CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

Certain statements contained in this prospectus are not statements of historical fact and constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act (the “Act”), including, without limitation, the statements specifically identified as forward-looking statements within this prospectus. Many of these statements contain risk factors as well. Words such as “may,” “might,” “should,” “believe,” “expect,” “anticipate,” “estimate,” “continue,” “predict,” “forecast,” “project,” “plan,” “intend” or similar expressions, or statements regarding intent, belief, or current expectations, are forward-looking statements. These forward-looking statements are based upon current estimates and assumptions.

These forward–looking statements rely on a number of assumptions concerning future events and are subject to a number of uncertainties and factors that could cause actual results to differ materially from such statements, many of which are outside the control of the Company. Forward–looking information includes, but is not limited to statements regarding: guidance or estimates related to EBITDA growth, projected capital expenditures; returns on invested capital, fundamentals of the compression industry and related oil and gas industry, valuations, compressor demand assumptions and overall industry outlook, and the ability of the Company to capitalize on any potential opportunities.

While we believe that the assumptions concerning future events are reasonable, investors are cautioned that there are inherent difficulties in predicting certain important factors that could impact the financial condition or future performance or results of our business.

In addition, certain statements in future filings by the Company with the Securities and Exchange Commission (“SEC”), in press releases, and in oral and written statements made by or with the approval of the Company which are not statements of historical fact constitute forward-looking statements within the meaning of the Act. Examples of forward-looking statements, include, but are not limited to:

•    conditions in the oil and natural gas industry, including the supply and demand for oil and natural gas and wide fluctuations and possible prolonged depression in the prices of oil and natural gas;

•    our reliance on one or more major customers;

•    fluctuations in interest rates and our ability to service our outstanding debt obligations;

•    economic challenges presently faced by our customers in the oil and natural gas business that, in turn, could adversely affect our sales, rentals and collectability of our accounts receivable;

•    regulation or prohibition of new well completion techniques;

•    competition among the various providers of compression services and products;

    -1-


•    the Company’s ability to economically develop and deploy new technologies and services, including technology to comply with health, safety and environmental laws and regulations;

•    changes in economic or political conditions in the markets in which we operate;

•    failure of our customers to continue to rent equipment after expiration of the primary rental term;

•    our ability to find and retain highly skill personnel, key members of senior management and key technical and financial employees;

•    the inherent risks associated with our operations, such as equipment defects, malfunctions and natural disasters;

•    our inability to comply with covenants in our debt agreements and the decreased financial flexibility associated with our debt;

•    achieving increased utilization of assets, including rental fleet utilization and unlocking other non-cash balance sheet assets;

•    our inability to comply with covenants in our debt agreements and the decreased financial flexibility associated with our debt;

risks in connection with potential acquisitions and the integration of significant acquisitions or assets acquired through a merger or otherwise;

future capital requirements, availability of financing and inability to finance capital expenditures;

•    the possibility that acquisitions and divestitures may involve unexpected costs or delays, and those acquisitions may not achieve intended benefits;

•    unanticipated reductions in the borrowing base under the credit agreement we are party to;

•    capacity availability, costs and performance of our outsourced compressor fabrication providers and overall inflationary pressures;

• general economic conditions, whether internationally, nationally or in the regional and local market areas in which we conduct business, may be less favorable than expected, including the possibility that economic conditions in the United States will worsen and that capital markets for equity and debt will be disrupted or unavailable;

•    significant economic disruptions and adverse consequences resulting from current and possible long-term effects of the COVID-19 global pandemic and other potential pandemics and other public health crises;

    -2-


•    acts of terrorism or sabotage, social unrest, political instability, or armed conflict in major oil and natural gas producing regions outside the United States, including evolving geopolitical and military hostilities in the Middle East, Russia;

•    possible adverse results from litigation and the use of financial resources to defend ourselves; and

the other factors discussed elsewhere in this prospectus and under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2023.

Such forward-looking statements speak only as of the date on which such statements are made, and the Company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made to reflect the occurrence of unanticipated events.

RISK FACTORS

Any investment in our securities involves risk. You should consider carefully the risk factors described in our periodic reports filed with the SEC (including the risks, uncertainties and assumptions discussed under the heading “Risk Factors” included in our most recent annual report on Form 10-K, as such may be revised or supplemented prior to the completion of this offering by more recently filed quarterly reports on Form 10-Q, each of which is or upon filing will be incorporated herein by reference), which may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future, and those identified in any applicable prospectus supplement, as well as other information in this prospectus and any applicable prospectus supplement and the documents incorporated by reference herein before purchasing any of our securities. Each of these risk factors could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our securities. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations.

SECURITIES WE MAY OFFER

The descriptions of the securities contained in this prospectus, together with the applicable prospectus supplements, summarize all of the material terms and provisions of the various types of securities that we may offer. We will describe in the applicable prospectus supplement relating to any securities the particular terms of the securities offered by that prospectus supplement. We will indicate in the applicable prospectus supplement whether the terms of the securities differ from the terms we have summarized below. We will also include in the prospectus supplement information, where applicable, about material United States federal income tax considerations relating to the securities, and the securities exchange, if any, on which the securities will be listed.

DESCRIPTION OF COMMON STOCK AND PREFERRED STOCK

The following description of our common stock and preferred stock, together with any additional information we include in any applicable prospectus supplement or any related free writing prospectus, summarizes the material terms and provisions of our common stock and the preferred stock that we may offer under this prospectus. While the terms we have summarized below will apply generally to any future common stock or preferred stock that we may offer, we will describe the particular terms of any class or series of these securities in more detail in the applicable prospectus supplement. For the complete terms of our common stock and preferred stock, please refer to our Articles of Incorporation, as amended and Bylaws that are incorporated by reference into the registration statement of which this prospectus is a part or may be incorporated by reference in this prospectus or any applicable prospectus supplement. The terms of these securities may also be affected by the Colorado Business Corporation Act. The summary
    -5-


below and that contained in any applicable prospectus supplement or any related free writing prospectus are qualified in their entirety by reference to our Articles of Incorporation, as amended and our Bylaws.

Common Stock

We are currently authorized to issue 30,000,000 shares of Common Stock, and as of December 12, 2024, (i) 12,490,353 shares of Common Stock were issued and outstanding, (ii) 1,000,000 shares were reserved for issuance under our 1998 Stock Option Plan, of which 405,919 shares remain unissued; and (iii) 1,150,000 shares were reserved for issuance under our 2019 Equity Incentive Plan, as amended, of which 278,113 shares remain unissued and not subject to outstanding awards.

Voting Rights

Each share of Common Stock entitles the holder thereof to one vote on each matter for which shareholders are entitled to vote. A majority of the outstanding shares of our Common Stock of the Company entitled to vote at meetings of shareholders, present in person or by proxy, constitute a quorum at any meeting of shareholders. Matters are generally decided by the affirmative vote of a majority of the shares of our Common Stock present in person or by proxy and entitled to vote. Our Board of Directors is elected by plurality and cumulative voting is not allowed. Thus, at each election of directors, that number of candidates equaling the number of directors to be elected, having the highest number of votes cast in favor of their election, shall be elected to our Board of Directors.

Dividends

Holders of Common Stock are entitled to dividends out of funds legally available for such dividends when, if and as declared by the Board of Directors.

Liquidation

In event of the voluntary or involuntary liquidation, dissolution, distribution of assets or other winding up, holders of our common stock have the right to receive ratably all of the assets remaining after payment of liabilities and liquidation preferences of any preferred stock then outstanding.

Other Matters

Shares of Common Stock are not liable to assessment or further call. Our Common Stock has no preemptive, conversion or other subscription rights. There are no redemption or sinking fund provisions applicable to our Common Stock.

Preferred Stock
 
We are authorized to issue 5,000,000 shares of preferred stock, none of which are issued and outstanding as of the date of this prospectus. Our Board of Directors is authorized to classify
    -6-


or reclassify any unissued portion of our authorized shares of preferred stock to provide for the issuance of shares of other classes or series, including preferred stock in one or more series. We may issue preferred stock from time to time in one or more class or series, with the exact terms of each class or series established by our Board of Directors. Our Board of Directors may issue preferred stock with voting and other rights that could adversely affect the voting power of the holders of our common stock without seeking shareholder approval. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of the common stock and may adversely affect the voting power of holders of common stock and reduce the likelihood that common shareholders will receive dividend payments and payments upon liquidation.

The rights, preferences, privileges and restrictions of the preferred stock of each series will be fixed by a certificate of designation relating to each series. We will incorporate by reference into the registration statement of which this prospectus is a part the form of any certificate of designation that describes the terms of the series of preferred stock we are offering before the issuance of such related series of preferred stock. The applicable prospectus supplement will specify the terms of the series of preferred stock we are offering, including, but not limited to:

the distinctive designation and the maximum number of shares in the series;
the number of shares we are offering and purchase price per share;
the liquidation preference, if any;
the terms on which dividends, if any, will be paid;
the voting rights, if any, on the shares of the series;
the terms and conditions, if any, on which the shares of the series shall be convertible into, or exchangeable for, shares of any other class or classes of capital stock;
the terms on which the shares may be redeemed, if at all;
any listing of the preferred stock on any securities exchange or market;
a discussion of any material or special United States federal income tax considerations applicable to the preferred stock; and
any or all other preferences, rights, restrictions, including restrictions on transferability, and qualifications of shares of the series.

The issuance of preferred stock may delay, deter or prevent a change in control.
 
Anti-Takeover Effects of Provisions of our Charter Documents and Colorado Law
 
The following is a summary of certain provisions of Colorado law, our amended articles of incorporation and bylaws. This summary does not purport to be complete and is qualified in its entirety by reference to the corporate law of Colorado and our amended articles of incorporation and bylaws.

Size of Board. Our Bylaws provide that the size of our Board of Directors may not be changed except (i) by a resolution adopted by at least 80% of the votes entitled to be cast by each shareholder voting group entitled to vote thereon, or (ii) by unanimous consent of the Board of Directors. This provision of the Bylaws may not be changed except upon approval by at least 80% of the votes entitled to be cast by each voting group entitled to vote thereon.

    -7-


Filling Vacancies on Board. Except with respect to a vacancy on the Board of Directors due to the removal of a Director, any vacancy on the Board may be filled by the affirmative vote of a majority of the shareholders or the Board of Directors. As a result of the ability of the Board to fill a vacancy, such new directors may not be up for shareholder election at the next annual meeting due to the staggered Board classification described below. The overall effect of these provisions may be to prevent a person or entity from immediately acquiring Board control.

Removal of Directors. Our Bylaws provide that any Director or the entire Board of Directors may be removed for cause only at a special meeting of the shareholders by the affirmative vote of at least 80% of the votes entitled to be cast by each voting group entitled to vote thereon at such meeting, if notice of the intention to act upon such matter shall have been given in the notice calling the meeting. The Bylaws also provide that vacancies arising as a result of the removal of directors by shareholder action may be filled at such meeting by the affirmative vote of at least 80% of the shares of the votes entitled to be cast by each voting group entitled to vote thereon. This provision of the Bylaws may not be changed except upon approval by at least 80% of the votes entitled to be cast by each voting group entitled to vote thereon.

Staggered Board of Directors. Our amended articles of incorporation provide that the Board of Directors is to be divided into three classes, each class to be as nearly equal in number as possible. At each annual meeting of shareholders, members of one of the classes, on a rotating basis, are elected for a three year term. The staggered Board provision cannot be amended or repealed by the directors and cannot be amended or repealed without the affirmative vote of the holders of at least 80% of the votes entitled to be cast in the election of directors.

Requirements for Advance Notification of Stockholder Nominations and Proposals. Our bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors.

Limited Ability for Shareholders to Call a Special Meeting. Our Bylaws only permit shareholders to call a special meeting if we receive one or more written demands for the meeting, stating the purpose or purposes of the meeting, signed and dated by holders of shares representing at least 10% of all votes entitled to be cast on any issue proposed to be considered at the meeting.

No cumulative voting. Cumulative voting in the election of directors is not allowed.

Indemnification. Our Articles of Incorporation, as amended, and Bylaws provide that our directors and officers shall be indemnified and shall be advanced expenses incurred in defending a civil, criminal, administrative or investigative action, suit or proceeding arising out of their status as directors and officers to the fullest extent allowed by law.

The limitation of liability and indemnification provisions included in the articles of incorporation, bylaws and in any indemnification agreements that the Company may enter into with its directors and executive officers may discourage stockholders from bringing a lawsuit against its directors and executive officers for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against its directors and executive officers, even though an action, if successful, might benefit the Company and its stockholders. Further, a stockholder’s investment may be adversely affected to the extent that the Company pays the
    -8-


costs of settlement and damage awards against directors and executive officers as required by these indemnification provisions.

The Company has obtained insurance policies under which, subject to the limitations of the policies, coverage is provided to its directors and executive officers against loss arising from claims made by reason of breach of fiduciary duty or other wrongful acts as a director or executive officer, including claims relating to public securities matters, and to the Company with respect to payments that may be made by it to these directors and executive officers pursuant to its indemnification obligations or otherwise as a matter of law.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, the Company has been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Listing
Our common stock is listed on the NYSE under the symbol “NGS.”


DESCRIPTION OF DEBT SECURITIES AND GUARANTEES

The Debt Securities may be either our senior debt securities (“Senior Debt Securities”) or our subordinated debt securities (“Subordinated Debt Securities”) or a combination of both and may be secured or unsecured. The Senior Debt Securities and the Subordinated Debt Securities will be issued under separate indentures among us, the Subsidiary Guarantors of such Debt Securities, if any, and a trustee to be determined (the “Trustee”). Senior Debt Securities will be issued under a “Senior Indenture” and Subordinated Debt Securities will be issued under a “Subordinated Indenture.” Together, the Senior Indenture and the Subordinated Indenture are called “Indentures.”

The Debt Securities may be issued from time to time in one or more series. The particular terms of each series that are offered by a prospectus supplement will be described in such prospectus supplement.

Unless the Debt Securities are guaranteed by our subsidiaries as described below, the rights of The Company and its creditors, including holders of the Debt Securities, to participate in the assets of any subsidiary upon the latter’s liquidation or reorganization, will be subject to the prior claims of the subsidiary’s creditors, except to the extent that the Company may be a creditor with recognized claims against such subsidiary.

We have summarized selected provisions of the Indentures below. The summary is not complete. The form of each Indenture has been filed with the SEC as an exhibit to the registration statement of which this prospectus is a part, and you should read the Indentures for provisions that may be important to you. Capitalized terms used in the summary have the meanings specified in the Indentures.

    -9-


General

The Indentures provide that Debt Securities in separate series may be issued thereunder from time to time without limitation as to aggregate principal amount. We may specify a maximum aggregate principal amount for the Debt Securities of any series. We will determine the terms and conditions of the Debt Securities, including the maturity, principal and interest. Unless indicated in a prospectus supplement applicable to a series of Debt Securities, the Debt Securities may be our secured or unsecured obligations.

The Subordinated Debt Securities will be subordinated in right of payment to the prior payment in full of all of our Senior Debt as described under “—Subordination of Subordinated Debt Securities” and in the prospectus supplement applicable to any Subordinated Debt Securities. If the prospectus supplement so indicates, the Debt Securities will be convertible into our common stock.

If specified in the prospectus supplement respecting a particular series of Debt Securities, certain subsidiaries of the Company (each a “Subsidiary Guarantor”) will fully and unconditionally guarantee (the “Subsidiary Guarantee”) that series as described under “—Subsidiary Guarantee” and in the prospectus supplement. Each Subsidiary Guarantee will be an unsecured obligation of the Subsidiary Guarantor. A Subsidiary Guarantee of Subordinated Debt Securities will be subordinated to the Senior Debt of the Subsidiary Guarantor on the same basis as the Subordinated Debt Securities are subordinated to our Senior Debt.

The applicable prospectus supplement will set forth the price or prices at which the Debt Securities to be issued will be offered for sale and will describe the following terms of such Debt Securities:

(1)    the title of the Debt Securities;

(2)    whether the Debt Securities are Senior Debt Securities or Subordinated Debt Securities and, if Subordinated Debt Securities, the related subordination terms;

(3)    whether any Subsidiary Guarantor will provide a Subsidiary Guarantee of the Debt Securities;

(4)     any limit on the aggregate principal amount of the Debt Securities;

(5)     each date on which the principal of the Debt Securities will be payable;

(6)     the interest rate that the Debt Securities will bear and the interest payment dates for the Debt Securities;

(7)     each place where payments on the Debt Securities will be payable;

(8)     any terms upon which the Debt Securities may be redeemed, in whole or in part, at our option;

    -10-


(9)    any sinking fund or other provisions that would obligate us to redeem or otherwise repurchase the Debt Securities;

(10)     the portion of the principal amount, if less than all, of the Debt Securities that will be payable upon declaration of acceleration of the Maturity of the Debt Securities;

(11)     whether the Debt Securities are defeasible;

(12)     any addition to or change in the Events of Default;

(13)     whether the Debt Securities are convertible into our common stock and, if so, the terms and conditions upon which conversion will be effected, including the initial conversion price or conversion rate and any adjustments thereto and the conversion period;

(14)     any addition to or change in the covenants in the Indenture applicable to the Debt Securities; and

(15)     any other terms of the Debt Securities not inconsistent with the provisions of the Indenture, except as permitted by clause (12) of the first paragraph under the caption “—Modification and Waiver.”

Debt Securities, including any Debt Securities that provide for an amount less than the principal amount thereof to be due and payable upon a declaration of acceleration of the Maturity thereof (“Original Issue Discount Securities”), may be sold at a substantial discount below their principal amount. Special United States federal income tax considerations applicable to Debt Securities sold at an original issue discount may be described in the applicable prospectus supplement. In addition, special United States federal income tax or other considerations applicable to any Debt Securities that are denominated in a currency or currency unit other than United States dollars may be described in the applicable prospectus supplement.

Subordination of Subordinated Debt Securities

The indebtedness evidenced by the Subordinated Debt Securities will, to the extent set forth in the Subordinated Indenture with respect to each series of Subordinated Debt Securities, be subordinated in right of payment to the prior payment in full of all of our Senior Debt, including the Senior Debt Securities, and it may also be senior in right of payment to all of our Subordinated Debt. The prospectus supplement relating to any Subordinated Debt Securities will summarize the subordination provisions of the Subordinated Indenture applicable to that series including:

the applicability and effect of such provisions upon any payment or distribution respecting that series following any liquidation, dissolution or other winding-up, or any assignment for the benefit of creditors or other marshalling of assets or any bankruptcy, insolvency or similar proceedings;

    -11-


the applicability and effect of such provisions in the event of specified defaults with respect to any Senior Debt, including the circumstances under which and the periods during which we will be prohibited from making payments on the Subordinated Debt Securities; and

the definition of Senior Debt applicable to the Subordinated Debt Securities of that series and, if the series is issued on a senior subordinated basis, the definition of Subordinated Debt applicable to that series.

The prospectus supplement will also describe, as of a recent date, the approximate amount of Senior Debt to which the Subordinated Debt Securities of that series will be subordinated.

The failure to make any payment on any of the Subordinated Debt Securities by reason of the subordination provisions of the Subordinated Indenture described in the prospectus supplement will not be construed as preventing the occurrence of an Event of Default with respect to the Subordinated Debt Securities arising from any such failure to make payment.

The subordination provisions described above will not be applicable to payments in respect of the Subordinated Debt Securities from a defeasance trust established in connection with any legal defeasance or covenant defeasance of the Subordinated Debt Securities as described below under “—Legal Defeasance and Covenant Defeasance.”

Subsidiary Guarantee

If specified in the prospectus supplement, one or more of the Subsidiary Guarantors will guarantee the Debt Securities of a series. Unless otherwise indicated in the prospectus supplement, the following provisions will apply to the Subsidiary Guarantee of the Subsidiary Guarantor.

Subject to the limitations described below and in the prospectus supplement, one or more of the Subsidiary Guarantors will jointly and severally, fully and unconditionally guarantee the punctual payment when due, whether at Stated Maturity, by acceleration or otherwise, of all our payment obligations under the Indentures and the Debt Securities of a series, whether for principal of, premium, if any, or interest on the Debt Securities or otherwise (all such obligations guaranteed by a Subsidiary Guarantor being herein called the “Guaranteed Obligations”). The Subsidiary Guarantors will also pay all expenses (including reasonable counsel fees and expenses) incurred by the applicable Trustee in enforcing any rights under a Subsidiary Guarantee with respect to a Subsidiary Guarantor.

In the case of Subordinated Debt Securities, a Subsidiary Guarantor’s Subsidiary Guarantee will be subordinated in right of payment to the Senior Debt of such Subsidiary Guarantor on the same basis as the Subordinated Debt Securities are subordinated to our Senior Debt. No payment will be made by any Subsidiary Guarantor under its Subsidiary Guarantee during any period in which payments by us on the Subordinated Debt Securities are suspended by the subordination provisions of the Subordinated Indenture.

    -12-


Each Subsidiary Guarantee will be limited in amount to an amount not to exceed the maximum amount that can be guaranteed by the relevant Subsidiary Guarantor without rendering such Subsidiary Guarantee voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally

Each Subsidiary Guarantee will be a continuing guarantee and will:

(1)    remain in full force and effect until either (a) payment in full of all the applicable Debt Securities (or such Debt Securities are otherwise satisfied and discharged in accordance with the provisions of the applicable Indenture) or (b) released as described in the following paragraph;

(2)    be binding upon each Subsidiary Guarantor; and

(3)    inure to the benefit of, and be enforceable by, the applicable Trustee, the Holders and their successors, transferees and assigns.

In the event that (a) a Subsidiary Guarantor ceases to be a Subsidiary, (b) either legal defeasance or covenant defeasance occurs with respect to the series or (c) all or substantially all of the assets or all of the Capital Stock of such Subsidiary Guarantor is sold, including by way of sale, merger, consolidation or otherwise, such Subsidiary Guarantor will be released and discharged of its obligations under its Subsidiary Guarantee without any further action required on the part of the Trustee or any Holder, and no other person acquiring or owning the assets or Capital Stock of such Subsidiary Guarantor will be required to enter into a Subsidiary Guarantee. In addition, the prospectus supplement may specify additional circumstances under which a Subsidiary Guarantor can be released from its Subsidiary Guarantee.

Form, Exchange and Transfer

The Debt Securities of each series will be issuable only in fully registered form, without coupons, and, unless otherwise specified in the applicable prospectus supplement, only in denominations of $1,000 and integral multiples thereof.

At the option of the Holder, subject to the terms of the applicable Indenture and the limitations applicable to Global Securities, Debt Securities of each series will be exchangeable for other Debt Securities of the same series of any authorized denomination and of a like tenor and aggregate principal amount.

Subject to the terms of the applicable Indenture and the limitations applicable to Global Securities, Debt Securities may be presented for exchange as provided above or for registration of transfer (duly endorsed or with the form of transfer endorsed thereon duly executed) at the office of the Security Registrar or at the office of any transfer agent designated by us for such purpose. No service charge will be made for any registration of transfer or exchange of Debt Securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in that connection. Such transfer or exchange will be effected upon the Security Registrar or such transfer agent, as the case may be, being satisfied with the documents of title and identity of the person making the request. The Security Registrar and any
    -13-


other transfer agent initially designated by us for any Debt Securities will be named in the applicable prospectus supplement. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each Place of Payment for the Debt Securities of each series.

If the Debt Securities of any series (or of any series and specified tenor) are to be redeemed in part, we will not be required to (1) issue, register the transfer of or exchange any Debt Security of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any such Debt Security that may be selected for redemption and ending at the close of business on the day of such mailing or (2) register the transfer of or exchange any Debt Security so selected for redemption, in whole or in part, except the unredeemed portion of any such Debt Security being redeemed in part.

Global Securities

Some or all of the Debt Securities of any series may be represented, in whole or in part, by one or more Global Securities that will have an aggregate principal amount equal to that of the Debt Securities they represent. Each Global Security will be registered in the name of a Depositary or its nominee identified in the applicable prospectus supplement, will be deposited with such Depositary or nominee or its custodian and will bear a legend regarding the restrictions on exchanges and registration of transfer thereof referred to below and any such other matters as may be provided for pursuant to the applicable Indenture.

Notwithstanding any provision of the Indentures or any Debt Security described in this prospectus, no Global Security may be exchanged in whole or in part for Debt Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or any nominee of such Depositary unless:

(1)the Depositary has notified us that it is unwilling or unable to continue as Depositary for such Global Security or has ceased to be qualified to act as such as required by the applicable Indenture, and in either case we fail to appoint a successor Depositary within 90 days;

(2)an Event of Default with respect to the Debt Securities represented by such Global Security has occurred and is continuing and the Trustee has received a written request from the Depositary to issue certificated Debt Securities;

(3)subject to the rules of the Depositary, we shall have elected to terminate the book-entry system through the Depositary; or

(4)other circumstances exist, in addition to or in lieu of those described above, as may be described in the applicable prospectus supplement.

    -14-


All certificated Debt Securities issued in exchange for a Global Security or any portion thereof will be registered in such names as the Depositary may direct.

As long as the Depositary, or its nominee, is the registered holder of a Global Security, the Depositary or such nominee, as the case may be, will be considered the sole owner and Holder of such Global Security and the Debt Securities that it represents for all purposes under the Debt Securities and the applicable Indenture. Except in the limited circumstances referred to above, owners of beneficial interests in a Global Security will not be entitled to have such Global Security or any Debt Securities that it represents registered in their names, will not receive or be entitled to receive physical delivery of certificated Debt Securities in exchange for those interests and will not be considered to be the owners or Holders of such Global Security or any Debt Securities that it represents for any purpose under the Debt Securities or the applicable Indenture. All payments on a Global Security will be made to the Depositary or its nominee, as the case may be, as the Holder of the security. The laws of some jurisdictions may require that some purchasers of Debt Securities take physical delivery of such Debt Securities in certificated form. These laws may impair the ability to transfer beneficial interests in a Global Security.

Ownership of beneficial interests in a Global Security will be limited to institutions that have accounts with the Depositary or its nominee (“participants”) and to persons that may hold beneficial interests through participants. In connection with the issuance of any Global Security, the Depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of Debt Securities represented by the Global Security to the accounts of its participants. Ownership of beneficial interests in a Global Security will be shown only on, and the transfer of those ownership interests will be effected only through, records maintained by the Depositary (with respect to participants’ interests) or any such participant (with respect to interests of Persons held by such participants on their behalf). Payments, transfers, exchanges and other matters relating to beneficial interests in a Global Security may be subject to various policies and procedures adopted by the Depositary from time to time. None of us, the Subsidiary Guarantors, the Trustees or the agents of us, the Subsidiary Guarantors or the Trustees will have any responsibility or liability for any aspect of the Depositary’s or any participant’s records relating to, or for payments made on account of, beneficial interests in a Global Security, or for maintaining, supervising or reviewing any records relating to such beneficial interests.

Payment and Paying Agents

Unless otherwise indicated in the applicable prospectus supplement, payment of interest on a Debt Security on any Interest Payment Date will be made to the Person in whose name such Debt Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Unless otherwise indicated in the applicable prospectus supplement, payment of interest on a Debt Security on any Interest Payment Date will be made to the Person in whose name such Debt Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Unless otherwise indicated in the applicable prospectus supplement, principal of and any premium and interest on the Debt Securities of a particular series will be payable at the office of
    -15-


such Paying Agent or Paying Agents as we may designate for such purpose from time to time, except that at our option payment of any interest on Debt Securities in certificated form may be made by check mailed to the address of the Person entitled thereto as such address appears in the Security Register. Unless otherwise indicated in the applicable prospectus supplement, the corporate trust office of the Trustee under the Senior Indenture in The City of New York will be designated as sole Paying Agent for payments with respect to Senior Debt Securities of each series, and the corporate trust office of the Trustee under the Subordinated Indenture in The City of New York will be designated as the sole Paying Agent for payment with respect to Subordinated Debt Securities of each series. Any other Paying Agents initially designated by us for the Debt Securities of a particular series will be named in the applicable prospectus supplement. We may at any time designate additional Paying Agents or rescind the designation of any Paying Agent or approve a change in the office through which any Paying Agent acts, except that we will be required to maintain a Paying Agent in each Place of Payment for the Debt Securities of a particular series.

Subject to applicable abandoned property laws, all money paid by us to a Paying Agent for the payment of the principal of or any premium or interest on any Debt Security which remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the Holder of such Debt Security thereafter may look only to us for payment.

Consolidation, Merger and Sale of Assets

Unless otherwise specified in the prospectus supplement, we may not consolidate with or merge into, or transfer, lease or otherwise dispose of all or substantially all of our assets to, any Person (a “successor Person”), and may not permit any Person to consolidate with or merge into us, unless:

(1)     the successor Person (if not us) is a corporation, partnership, trust or other entity organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia and assumes our obligations on the Debt Securities and under the Indentures;

(2)     immediately before and after giving pro forma effect to the transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, has occurred and is continuing; and

(3)     several other conditions, including any additional conditions with respect to any particular Debt Securities specified in the applicable prospectus supplement, are met.

The successor Person (if not us) will be substituted for us under the applicable Indenture with the same effect as if it had been an original party to such Indenture, and, except in the case of a lease, we will be relieved from any further obligations under such Indenture and the Debt Securities.

    -16-


Events of Default

Unless otherwise specified in the prospectus supplement, each of the following will constitute an Event of Default under the applicable Indenture with respect to Debt Securities of any series:

(1)failure to pay principal of or any premium on any Debt Security of that series when due, whether or not, in the case of Subordinated Debt Securities, such payment is prohibited by the subordination provisions of the Subordinated Indenture;

(2)failure to pay any interest on any Debt Securities of that series when due, continued for 30 days, whether or not, in the case of Subordinated Debt Securities, such payment is prohibited by the subordination provisions of the Subordinated Indenture;

(3)failure to deposit any sinking fund payment, when due, in respect of any Debt Security of that series, whether or not, in the case of Subordinated Debt Securities, such deposit is prohibited by the subordination provisions of the Subordinated Indenture;

(4)failure to perform or comply with the provisions described under “—Consolidation, Merger and Sale of Assets” above;

(5)failure to perform any of our other covenants in such Indenture (other than a covenant included in such Indenture solely for the benefit of a series other than that series), continued for 60 days after written notice has been given by the applicable Trustee, or the Holders of at least 25% in principal amount of the Outstanding Debt Securities of that series, as provided in such Indenture;

(6)any Debt of ours, any Significant Subsidiary or, if a Subsidiary Guarantor has guaranteed the series, such Subsidiary Guarantor, is not paid within any applicable grace period after final maturity or is accelerated by its holders because of a default and the total amount of such Debt unpaid or accelerated exceeds $25.0 million; provided, however, that if any such default is cured or waived or any such acceleration rescinded, or such Debt is repaid, within a period of 30 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequential acceleration of the Debt Securities shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree;

(7)any judgment or decree for the payment of money in excess of $25.0 million (net of any amounts covered by insurance or a binding indemnity agreement) is entered against us, any Significant Subsidiary or, if a Subsidiary Guarantor has guaranteed the series, such Subsidiary Guarantor, remains outstanding for a
    -17-


period of 60 consecutive days following entry of such judgment and is not discharged, waived or stayed;

(8)certain events of bankruptcy, insolvency or reorganization affecting us, any Significant Subsidiary or, if a Subsidiary Guarantor has guaranteed the series, such Subsidiary Guarantor; and

(9)if any Subsidiary Guarantor has guaranteed such series, the Subsidiary Guarantee of any such Subsidiary Guarantor is held by a final non-appealable order or judgment of a court of competent jurisdiction to be unenforceable or invalid or ceases for any reason to be in full force and effect (other than in accordance with the terms of the applicable Indenture) or any Subsidiary Guarantor or any Person acting on behalf of any Subsidiary Guarantor denies or disaffirms such Subsidiary Guarantor’s obligations under its Subsidiary Guarantee (other than by reason of a release of such Subsidiary Guarantor from its Subsidiary Guarantee in accordance with the terms of the applicable Indenture).

If an Event of Default (other than an Event of Default with respect to Natural Gas Services Group, Inc. described in clause (8) above) with respect to the Debt Securities of any series at the time Outstanding occurs and is continuing, either the applicable Trustee or the Holders of at least 25% in principal amount of the Outstanding Debt Securities of that series by notice as provided in the Indenture may declare the principal amount of the Debt Securities of that series (or, in the case of any Debt Security that is an Original Issue Discount Debt Security, such portion of the principal amount of such Debt Security as may be specified in the terms of such Debt Security) to be due and payable immediately, together with any accrued and unpaid interest thereon. If an Event of Default with respect to Natural Gas Services Group, Inc. described in clause (8) above with respect to the Debt Securities of any series at the time Outstanding occurs, the principal amount of all the Debt Securities of that series (or, in the case of any such Original Issue Discount Security, such specified amount) will automatically, and without any action by the applicable Trustee or any Holder, become immediately due and payable, together with any accrued and unpaid interest thereon. After any such acceleration and its consequences, but before a judgment or decree based on acceleration, the Holders of a majority in principal amount of the Outstanding Debt Securities of that series may, under certain circumstances, rescind and annul such acceleration if all Events of Default with respect to that series, other than the non-payment of accelerated principal (or other specified amount), have been cured or waived as provided in the applicable Indenture. For information as to waiver of defaults, see “—Modification and Waiver” below.

Subject to the provisions of the Indentures relating to the duties of the Trustees in case an Event of Default has occurred and is continuing, no Trustee will be under any obligation to exercise any of its rights or powers under the applicable Indenture at the request or direction of any of the Holders, unless such Holders have offered to such Trustee reasonable security or indemnity. Subject to such provisions for the indemnification of the Trustees, the Holders of a majority in principal amount of the Outstanding Debt Securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Debt Securities of that series.
    -18-



No Holder of a Debt Security of any series will have any right to institute any proceeding with respect to the applicable Indenture, or for the appointment of a receiver or a trustee, or for any other remedy thereunder, unless:

(1)such Holder has previously given to the Trustee under the applicable Indenture written notice of a continuing Event of Default with respect to the Debt Securities of that series;

(2)the Holders of at least 25% in principal amount of the Outstanding Debt Securities of that series have made written request, and such Holder or Holders have offered reasonable security or indemnity, to the Trustee to institute such proceeding as trustee; and

(3)the Trustee has failed to institute such proceeding and has not received from the Holders of a majority in principal amount of the Outstanding Debt Securities of that series a direction inconsistent with such request, within 60 days after such notice, request and offer.

However, such limitations do not apply to a suit instituted by a Holder of a Debt Security for the enforcement of payment of the principal of or any premium or interest on such Debt Security on or after the applicable due date specified in such Debt Security or, if applicable, to convert such Debt Security.

We will be required to furnish to each Trustee annually a statement by certain of our officers as to whether or not we, to their knowledge, are in default in the performance or observance of any of the terms, provisions and conditions of the applicable Indenture and, if so, specifying all such known defaults.

Modification and Waiver

We may modify or amend an Indenture without the consent of any holders of the Debt Securities in certain circumstances, including:

(1)to evidence the succession under the Indenture of another Person to us or any Subsidiary Guarantor and to provide for its assumption of our or such Subsidiary Guarantor’s obligations to holders of Debt Securities;

(2)to add any additional covenants of us or the Subsidiary Guarantors for the benefit of the holders of all or any series of Debt Securities or to surrender any right or power under the applicable Indenture conferred upon us or any Subsidiary Guarantor;

(3)to add any additional Events of Default with respect to all or any series of Debt Securities;

(4)to provide for uncertificated notes in addition to, or in place of, certificated notes;
    -19-



(5)to secure the Debt Securities;

(6)to establish the form or terms of any series of Debt Securities;

(7)to evidence and provide for the acceptance of appointment under the Indenture of a successor Trustee;

(8)to cure any ambiguity, defect or inconsistency;

(9)to add Subsidiary Guarantors;

(10)in the case of any Subordinated Debt Security, to make any change in the subordination provisions that limits or terminates the benefits applicable to any holder of Senior Debt;

(11)to make other changes that do not adversely affect the interests of the Holders of Debt Securities of any series issued thereunder in any material respect; or

(12)to add to, change or eliminate any of the provisions of the applicable Indenture in respect of one or more series of Debt Securities, provided that any such addition, change or elimination (a) shall neither (i) apply to any Debt Security of any series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor (ii) modify the rights of the Holder of any such Debt Security with respect to such provision or (b) shall become effective only when there is no such Debt Security Outstanding.

Other modifications and amendments of an Indenture may be made by us, the Subsidiary Guarantors, if applicable, and the applicable Trustee with the consent of the Holders of a majority in principal amount of the Outstanding Debt Securities of each series affected by such modification or amendment; provided, however, that no such modification or amendment may, without the consent of the Holder of each Outstanding Debt Security affected thereby:

(1)change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Debt Security;

(2)reduce the principal amount of, or any premium or interest on, any Debt Security;

(3)reduce the amount of principal of an Original Issue Discount Security or any other Debt Security payable upon acceleration of the Maturity thereof;

(4)change the place or currency of payment of principal of, or any premium or interest on, any Debt Security;

(5)impair the right to institute suit for the enforcement of any payment due on or any conversion right with respect to any Debt Security;

    -20-


(6)modify the subordination provisions in the case of Subordinated Debt Securities, or modify any conversion provisions, in either case in a manner adverse to the Holders of such Debt Securities;

(7)except as provided in the applicable Indenture, release the Subsidiary Guarantee of a Subsidiary Guarantor;

(8)reduce the percentage in principal amount of Outstanding Debt Securities of any series, the consent of whose Holders is required for modification or amendment of the Indenture;

(9)reduce the percentage in principal amount of Outstanding Debt Securities of any series necessary for waiver of compliance with certain provisions of the Indenture or for waiver of certain defaults;

(10)modify such provisions with respect to modification, amendment or waiver; or

(11)following the making of an offer to purchase Debt Securities from any Holder that has been made pursuant to a covenant in such Indenture, modify such covenant with respect to such offer in a manner adverse to such Holder.

The Holders of a majority in principal amount of the Outstanding Debt Securities of any series may waive compliance by us with certain restrictive provisions of the applicable Indenture. The Holders of a majority in principal amount of the Outstanding Debt Securities of any series may waive any past default under the applicable Indenture, except a default in the payment of principal, premium or interest and certain covenants and provisions of the Indenture which cannot be amended without the consent of the Holder of each Outstanding Debt Security of such series.

Each of the Indentures provides that in determining whether the Holders of the requisite principal amount of the Outstanding Debt Securities have given or taken any direction, notice, consent, waiver or other action under such Indenture as of any date:

(1)the principal amount of an Original Issue Discount Security that will be deemed to be Outstanding will be the amount of the principal that would be due and payable as of such date upon acceleration of Maturity to such date;

(2)if, as of such date, the principal amount payable at the Stated Maturity of a Debt Security is not determinable (for example, because it is based on an index), the principal amount of such Debt Security deemed to be Outstanding as of such date will be an amount determined in the manner prescribed for such Debt Security;

(3)the principal amount of a Debt Security denominated in one or more foreign currencies or currency units that will be deemed to be Outstanding will be the United States-dollar equivalent, determined as of such date in the manner prescribed for such Debt Security, of the principal amount of such Debt Security
    -21-


(or, in the case of a Debt Security described in clause (1) or (2) above, of the amount described in such clause); and

(4)certain Debt Securities, including those owned by us, any Subsidiary Guarantor or any of our other Affiliates, will not be deemed to be Outstanding.

Except in certain limited circumstances, we will be entitled to set any day as a record date for the purpose of determining the Holders of Outstanding Debt Securities of any series entitled to give or take any direction, notice, consent, waiver or other action under the applicable Indenture, in the manner and subject to the limitations provided in the Indenture. In certain limited circumstances, the Trustee will be entitled to set a record date for action by Holders. If a record date is set for any action to be taken by Holders of a particular series, only persons who are Holders of Outstanding Debt Securities of that series on the record date may take such action. To be effective, such action must be taken by Holders of the requisite principal amount of such Debt Securities within a specified period following the record date. For any particular record date, this period will be 180 days or such other period as may be specified by us (or the Trustee, if it set the record date), and may be shortened or lengthened (but not beyond 180 days) from time to time.

Satisfaction and Discharge

Each Indenture will be discharged and will cease to be of further effect as to all outstanding Debt Securities of any series issued thereunder, when:

(1)either:

(a)    all outstanding Debt Securities of that series that have been authenticated (except lost, stolen or destroyed Debt Securities that have been replaced or paid and Debt Securities for whose payment money has theretofore been deposited in trust and thereafter repaid to us) have been delivered to the Trustee for cancellation; or

(b)    all outstanding Debt Securities of that series that have been not delivered to the Trustee for cancellation have become due and payable or will become due and payable at their Stated Maturity within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee and in any case we have irrevocably deposited with the Trustee as trust funds money in an amount sufficient, without consideration of any reinvestment of interest, to pay the entire indebtedness of such Debt Securities not delivered to the Trustee for cancellation, for principal, premium, if any, and accrued interest to the Stated Maturity or redemption date;

(2)we have paid or caused to be paid all other sums payable by us under the Indenture with respect to the Debt Securities of that series; and

    -22-


(3)we have delivered an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge of the Indenture with respect to the Debt Securities of that series have been satisfied.

Legal Defeasance and Covenant Defeasance

To the extent indicated in the applicable prospectus supplement, we may elect, at our option at any time, to have our obligations discharged under provisions relating to defeasance and discharge of indebtedness, which we call “legal defeasance,” or relating to defeasance of certain restrictive covenants applied to the Debt Securities of any series, which we call “covenant defeasance.”

Legal Defeasance. The Indentures provide that, upon our exercise of our option (if any) to have the legal defeasance provisions applied to any series of Debt Securities, we and, if applicable, each Subsidiary Guarantor will be discharged from all our obligations, and, if such Debt Securities are Subordinated Debt Securities, the provisions of the Subordinated Indenture relating to subordination will cease to be effective, with respect to such Debt Securities (except for certain obligations to convert, exchange or register the transfer of Debt Securities, to replace stolen, lost or mutilated Debt Securities, to maintain paying agencies and to hold moneys for payment in trust) upon the deposit in trust for the benefit of the Holders of such Debt Securities of money or U.S. Government Obligations, or both, which, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient (in the opinion of a nationally recognized firm of independent public accountants) to pay the principal of and any premium and interest on such Debt Securities on the respective Stated Maturities in accordance with the terms of the applicable Indenture and such Debt Securities. Such defeasance or discharge may occur only if, among other things:

(1)we have delivered to the applicable Trustee an Opinion of Counsel to the effect that we have received from, or there has been published by, the United States Internal Revenue Service a ruling, or there has been a change in tax law, in either case to the effect that Holders of such Debt Securities will not recognize gain or loss for federal income tax purposes as a result of such deposit and legal defeasance and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and legal defeasance were not to occur;

(2)no Event of Default or event that with the passing of time or the giving of notice, or both, shall constitute an Event of Default shall have occurred and be continuing at the time of such deposit (other than a default or an Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness) and the granting of liens to secure such borrowing) or, with respect to any Event of Default described in clause (8) under “—Events of Default,” at any time until 121 days after such deposit;

    -23-


(3)such deposit and legal defeasance will not result in a breach or violation of, or constitute a default under, any agreement or instrument (other than the applicable Indenture) to which we are a party or by which we are bound;

(4)in the case of Subordinated Debt Securities, at the time of such deposit, no default in the payment of all or a portion of principal of (or premium, if any) or interest on any Senior Debt shall have occurred and be continuing, no event of default shall have resulted in the acceleration of any Senior Debt and no other event of default with respect to any Senior Debt shall have occurred and be continuing permitting after notice or the lapse of time, or both, the acceleration thereof; and
(5)we have delivered to the Trustee an Opinion of Counsel to the effect that such deposit shall not cause the Trustee or the trust so created to be subject to the Investment Company Act of 1940.

Covenant Defeasance. The Indentures provide that, upon our exercise of our option (if any) to have the covenant defeasance provisions applied to any Debt Securities, we may fail to comply with certain restrictive covenants (but not with respect to conversion, if applicable), including those that may be described in the applicable prospectus supplement, and the occurrence of certain Events of Default, which are described above in clause (5) (with respect to such restrictive covenants) and clauses (6), (7) and (9) under “Events of Default” and any that may be described in the applicable prospectus supplement, will not be deemed to either be or result in an Event of Default and, if such Debt Securities are Subordinated Debt Securities, the provisions of the Subordinated Indenture relating to subordination will cease to be effective, in each case with respect to such Debt Securities. In order to exercise such option, we must deposit, in trust for the benefit of the Holders of such Debt Securities, money or U.S. Government Obligations, or both, which, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient (in the opinion of a nationally recognized firm of independent public accountants) to pay the principal of and any premium and interest on such Debt Securities on the respective Stated Maturities in accordance with the terms of the applicable Indenture and such Debt Securities. Such covenant defeasance may occur only if we have delivered to the applicable Trustee an Opinion of Counsel to the effect that Holders of such Debt Securities will not recognize gain or loss for federal income tax purposes as a result of such deposit and covenant defeasance and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and covenant defeasance were not to occur, and the requirements set forth in clauses (2), (3) and (4) above are satisfied. If we exercise this option with respect to any series of Debt Securities and such Debt Securities were declared due and payable because of the occurrence of any Event of Default, the amount of money and U.S. Government Obligations so deposited in trust would be sufficient to pay amounts due on such Debt Securities at the time of their respective Stated Maturities but may not be sufficient to pay amounts due on such Debt Securities upon any acceleration resulting from such Event of Default. In such case, we would remain liable for such payments .

If we exercise either our legal defeasance or covenant defeasance option, any Subsidiary Guarantee will terminate.

No Personal Liability of Directors, Officers, Employees and Stockholders
    -24-



No director, officer, employee, incorporator, stockholder, member, manager, partner or trustee of the Company or any Subsidiary Guarantor, as such, shall have any liability for any obligations of the Company or any Subsidiary Guarantor under the Debt Securities, the Indentures or any Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. By accepting a Debt Security, each Holder shall be deemed to have waived and released all such liability. The waiver and release shall be a part of the consideration for the issue of the Debt Securities. The waiver may not be effective to waive liabilities under the federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Notices

Notices to Holders of Debt Securities will be given by mail to the addresses of such Holders as they may appear in the Security Register.

Title

    We, the Subsidiary Guarantors, the Trustees and any agent of us, the Subsidiary Guarantors or a Trustee may treat the Person in whose name a Debt Security is registered as the absolute owner of the Debt Security (whether or not such Debt Security may be overdue) for the purpose of making payment and for all other purposes.

Governing Law

The Indentures and the Debt Securities will be governed by, and construed in accordance with, the law of the State of New York.

The Trustee

We will enter into the Indentures with a Trustee that is qualified to act under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and with any other Trustees chosen by us and appointed in a supplemental indenture for a particular series of Debt Securities. We may maintain a banking relationship in the ordinary course of business with our Trustee and one or more of its affiliates.

Resignation or Removal of Trustee. If the Trustee has or acquires a conflicting interest within the meaning of the Trust Indenture Act, the Trustee must either eliminate its conflicting interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and the applicable Indenture. Any resignation will require the appointment of a successor Trustee under the applicable Indenture in accordance with the terms and conditions of such Indenture.

The Trustee may resign or be removed by us with respect to one or more series of Debt Securities and a successor Trustee may be appointed to act with respect to any such series. The holders of a majority in aggregate principal amount of the Debt Securities of any series may remove the Trustee with respect to the Debt Securities of such series.
    -25-



Limitations on Trustee if It is Our Creditor. Each Indenture will contain certain limitations on the right of the Trustee, in the event that it becomes our creditor, to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise.

Certificates and Opinions to Be Furnished to Trustee. Each Indenture will provide that, in addition to other certificates or opinions that may be specifically required by other provisions of an Indenture, every application by us for action by the Trustee must be accompanied by an officers’ certificate and an opinion of counsel stating that, in the opinion of the signers, all conditions precedent to such action have been complied with by us.

DESCRIPTION OF DEPOSITARY SHARES

We may offer fractional interests in shares of preferred stock rather than full shares of preferred stock. In that event, depositary receipts will be issued to evidence depositary shares, each of which will represent a fraction of a share of a particular series of preferred stock, as described in the prospectus supplement relating to the particular issue of depositary shares.

The shares of preferred stock represented by depositary shares will be deposited under a deposit agreement between us and a depositary that is a bank or trust company, as depositary, that we select as set forth in the prospectus supplement relating to the particular issue of depositary shares. Unless otherwise specified in the prospectus supplement relating to a particular issue of depositary shares, each owner of a depositary share will be entitled, in proportion to the applicable fraction of a share of preferred stock represented by such depositary share, to all the rights and preferences of the shares of preferred stock represented by such depositary share, including dividend and liquidation rights and any right to convert the shares of preferred stock into common stock.

We will describe the terms of any depositary shares we offer and the related depositary agreement, as well as the terms of the shares of preferred stock represented thereby, in the prospectus supplement relating to the particular issue of depositary shares.

DESCRIPTION OF WARRANTS

We may issue warrants that entitle the holder to purchase common stock, preferred stock, debt securities or other securities. Warrants may be issued independently or together with common stock, preferred stock, debt securities or other securities offered by any prospectus supplement and may be attached to or separate from any such offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent, all as will be set forth in the prospectus supplement relating to the particular issue of warrants. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders of warrants or beneficial owners of warrants.

    -26-


The following summary of certain provisions of the warrants does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all provisions of the warrant agreements.

Reference is made to the prospectus supplement relating to the particular issue of warrants offered pursuant to such prospectus supplement for the terms of and information relating to such warrants, including, where applicable:

the number of shares of common stock purchasable upon the exercise of warrants to purchase common stock and the price at which such number of shares of common stock may be purchased upon such exercise;

the number of shares and series of preferred stock purchasable upon the exercise of warrants to purchase preferred stock and the price at which such number of shares of such series of preferred stock may be purchased upon such exercise;

the designation, aggregate principal amount, denominations and terms of the series of debt securities purchasable upon exercise of warrants to purchase debt securities and the price at which such debt securities may be purchased upon such exercise;

the number of other securities purchasable upon exercise of the warrants to purchase such other securities and the price at which such securities may be purchased upon exercise;

the date on which the right to exercise such warrants shall commence and the date on which such right shall expire;

United States federal income tax consequences applicable to such warrants;

the amount of warrants outstanding as of the most recent practicable date; and

any other terms of such warrants.

Warrants will be offered and exercisable for United States dollars only. Warrants will be issued in registered form only. The exercise price for warrants will be subject to adjustment in accordance with the applicable prospectus supplement.

Each warrant will entitle the holder thereof to purchase such number of shares of common stock, preferred stock or other securities or such principal amount of debt securities at such exercise price as shall in each case be set forth in, or calculable from, the prospectus supplement relating to the warrants, which exercise price may be subject to adjustment upon the occurrence of certain events as set forth in such prospectus supplement. After the close of business on the expiration date, or such later date to which such expiration date may be extended by us, unexercised warrants will become void. The place or places where, and the manner in which, warrants may be exercised shall be specified in the prospectus supplement relating to such warrants.
    -27-



Prior to the exercise of any warrants to purchase common stock, preferred stock, debt securities or other securities, holders of such warrants will not have any of the rights of holders of such common stock, preferred stock, debt securities or other securities, as the case may be, purchasable upon such exercise, including the right to receive payments of dividends, if any, on the common stock or preferred stock purchasable upon such exercise, or to receive payments of principal of, premium, if any, or interest, if any, on the debt securities purchasable upon such exercise or to enforce covenants in the applicable indenture.

DESCRIPTION OF RIGHTS

We may issue rights to purchase our common stock, preferred stock, debt securities or depositary shares. These rights may be offered independently or together with any other security offered hereby and may or may not be transferable by the stockholder receiving the rights in such offering. In connection with any offering of rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed for after such offering.

The prospectus supplement relating to any rights we offer, if any, will, to the extent applicable, include specific terms relating to the offering, including some or all of the following:

the price, if any, for the rights;

the exercise price payable for our common stock, preferred stock, debt securities or depositary shares upon the exercise of the rights;

the number of rights to be issued to each stockholder;

the number and terms of our common stock, preferred stock, debt securities or depositary shares which may be purchased per each right;

the extent to which the rights are transferable;

any other terms of the rights, including the terms, procedures and limitations relating to the exchange and exercise of the rights;

the date on which the right to exercise the rights shall commence, and the date on which the rights shall expire;

the extent to which the rights may include an over-subscription privilege with respect to unsubscribed securities or an over-allotment privilege to the extent the securities are fully subscribed; and

if applicable, the material terms of any standby underwriting or purchase arrangement which we may enter into in connection with the offering of rights.

    -28-


The description in the applicable prospectus supplement of any rights we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable rights certificate, which will be filed with the SEC if we offer rights. We urge you to read the applicable rights certificate and any applicable prospectus supplement in their entirety.
    
DESCRIPTION OF UNITS

We may issue units comprised of one or more of the other classes of securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The units may be issued under unit agreements to be entered into between us and a unit agent, as detailed in the prospectus supplement relating to the units being offered. The prospectus supplement will describe:

the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances the securities comprising the units may be held or transferred separately;

a description of the terms of any unit agreement governing the units;

a description of the provisions for the payment, settlement, transfer or exchange of the units;

a discussion of material federal income tax considerations, if applicable; and

whether the units if issued as a separate security will be issued in fully registered or global form.

The descriptions of the units in this prospectus and in any prospectus supplement are summaries of the material provisions of the applicable agreements. These descriptions do not restate those agreements in their entirety and may not contain all the information that you may find useful. We urge you to read the applicable agreements because they, and not the summaries, define your rights as holders of the units. For more information, please review the forms of the relevant agreements, which will be filed with the SEC promptly after the offering of units and will be available as described in the sections titled “Where You Can Find More Information” and “Incorporation of Certain Information by Reference.”
        

USE OF PROCEEDS

Except as may be stated in the applicable prospectus supplement, we intend to use the net proceeds we receive from any sales of securities by us under this prospectus and any accompanying prospectus supplement for general and other corporate purposes, which may include, among other things:

capital expenditures associated with our rental fleet;
potential future acquisitions of companies;
    -29-


reduction or refinancing of debt or other corporate obligations; and
additions to our working capital.

If, as of the date of any prospectus supplement, we have identified any such uses, we will describe them in the prospectus supplement. The amount of our securities offered from time to time pursuant to this prospectus and any prospectus supplement, and the precise amounts and timing of the application of net proceeds from the sale of those securities, will depend upon our funding requirements. If we elect at the time of an issuance of our securities to make different or more specific use of proceeds than described in this prospectus, such use will be described in the prospectus supplement relating to those securities.

PLAN OF DISTRIBUTION

We may sell the offered securities in and outside the United States pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods. We may sell our securities separately or together (1) through underwriters or dealers, (2) directly to purchasers, including our affiliates and stockholders, (3) through agents or (4) through a combination of any of these methods. The prospectus supplement will include the following information:

the terms of the offering;

the names of any underwriters or agents;

the name or names of any managing underwriter or underwriters;

the purchase price of the securities;

the estimated net proceeds to us from the sale of the securities;

any delayed delivery arrangements;

any underwriting discounts, commissions and other items constituting underwriters' compensation;

any discounts or concessions allowed or reallowed or paid to dealers; and

any commissions paid to agents.

    -30-


Sale Through Underwriters or Dealers

If underwriters are used in the sale or a firm commitment basis, the underwriters will acquire the securities for their own account for resale to the public. The underwriters may also be engaged to sell our securities on a best-efforts basis. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless we inform you otherwise in the prospectus supplement and except as described below, the obligations of the underwriters to purchase the securities will be subject to certain conditions. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers.

During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, which means that selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if the offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, the underwriters may discontinue these activities at any time.

If dealers are used, we will sell the securities to them as principals. The dealers may then resell the securities to the public at varying prices determined by the dealers at the time of resale. The dealers participating in any sale of the securities may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. We will include in the prospectus supplement the names of the dealers and the terms of the transaction.

At-the-Market Offerings

    Underwriters or agents could make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an “at-the-market” offering as defined in Rule 415 under the Securities Act, which includes sales made directly on or through the NYSE, the existing trading market for our common stock, or sales made to or through a market maker other than on an exchange.

To the extent that we make sales through one or more underwriters or agents in “at-the-market” offerings, we will do so pursuant to the terms of a sales agency financing agreement or other “at-the-market” offering arrangement with such underwriters or agents. If we engage in at-the-market sales pursuant to any such agreement, we will issue and sell securities through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such agreement, we may sell securities on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents. The agreement will provide that any securities sold will be sold at prices related to the then prevailing market prices for such
    -31-


securities. Therefore, exact figures regarding proceeds that will be raised or commissions to be paid cannot be determined at this time. Pursuant to the terms of the agreement, we also may agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of securities. The terms of each such agreement will be set forth in more detail in the applicable prospectus supplement and any related free writing prospectus. In the event that any underwriter or agent acts as principal, or any broker-dealer acts as underwriter, it may engage in certain transactions that stabilize, maintain, or otherwise affect the price of the securities. Any such activities will be described in the prospectus supplement or any related free writing prospectus relating to the transaction.

Direct Sales and Sales Through Agents

We may sell the securities directly. In this case, no underwriters or agents would be involved. We may also sell the securities through agents we designate from time to time. In the prospectus supplement, we will name any agent involved in the offer or sale of the offered securities, and we will describe any commissions payable by us to the agent. Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. We will describe the terms of any such sales in the prospectus supplement.

Remarketing Arrangements

Offered securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms, acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreements, if any, with us and its compensation will be described in the applicable prospectus supplement. Remarketing firms may be deemed to be underwriters, as that term is defined in the Securities Act, in connection with the securities remarketed.

Delayed Delivery Contracts

If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The prospectus supplement will describe the commission payable for solicitation of those contracts.

    -32-


General Information

We may have agreements with the agents, dealers, underwriters and remarketing firms to indemnify them against certain civil liabilities, including liabilities under the Securities Act, or to contribute with respect to payments that the agents, dealers, underwriters or remarketing firms may be required to make. Agents, dealers, underwriters and remarketing firms may be customers of, engage in transactions with, or perform services for us in the ordinary course of their businesses.

LEGAL MATTERS

Unless otherwise indicated in the applicable prospectus supplement, Jones & Keller, P.C., Denver, Colorado will provide opinions regarding the authorization and validity of the securities. Jones & Keller, P.C. may also provide opinions regarding certain other matters. Any underwriters will also be advised about legal matters by their own counsel, which will be named in the prospectus supplement.

DISCLOSURE OF SEC POSITION ON INDEMNIFICATION
FOR SECURITIES ACT LIABILITIES

OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION, ESTIMATED

The following is a statement of the estimated costs and expenses, other than underwriting compensation, incurred or expected to be incurred by us in connection with the issuance and distribution of an assumed amount of $200,000,000 of securities being registered pursuant to this registration statement. The assumed amount has been used to demonstrate the costs and expenses of an offering of the entire assumed amount of securities being registered and does not represent an estimate of the amount of securities that may be offered because such amount is unknown at this time.

ITEM 15.
INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 7-109-102 of the Colorado Business Corporation Act permits a Colorado corporation to indemnify any director against liability if such person acted in good faith and, in the case of conduct in an official capacity with the corporation, that the director’s conduct was in the corporation’s best interests and, in all other cases, that the director’s conduct was at least not
    II-1


opposed to the best interests of the corporation or, with regard to criminal proceedings, the director had no reasonable cause to believe the director’s conduct was unlawful.

Section 7-109-103 of the Colorado Business Corporation Act provides that, unless limited by its articles of incorporation, a Colorado corporation shall indemnify a person who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which the person was a party because the person is or was a director, against reasonable expenses incurred by him or her in connection with the proceeding.

Section 3 of Article IX of our Articles of Incorporation, as amended, provides that we shall indemnify, to the maximum extent permitted by law in effect from time to time, any person who is or was a director, officer, agent, fiduciary or employee of ours against any claim, liability or expense arising against or incurred by such person made party to a proceeding because such person is or was a director, officer, agent, fiduciary or employee of ours or because such person is or was serving another entity as a director, officer, partner trustee, employee, fiduciary or agent at our request. We further have the authority to the maximum extent permitted by law to purchase and maintain insurance providing such indemnification.
 
 Article VI of our bylaws provides for the indemnification of certain persons.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable.

At present, there is no pending litigation or proceeding involving any of our directors, officers, employees or agents where indemnification will be required or permitted. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable.

(1)           To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

i.To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

ii.To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

iii.To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that

(A)paragraphs (1)(i), (1)(ii) and (1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is a part of the registration statement.

(B)Provided further, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) above do not apply if the registration statement is for an offering of asset-backed securities on Form S-1 or Form S-3, and the information required to be included in a post-effective amendment is provided pursuant to Item 1100(c) of Regulation AB.

(2)           That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
    II-4


(3)           To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

i.Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

ii.Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
 
(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

i.Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

ii.Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

    II-5


iii.The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

iv.Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

The undersigned registrant hereby undertakes that:

(1)  For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part of this registration statement as of the time it was declared effective.
 
     (2)   For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by
    II-6


controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06.
The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 5.02, (iii) any request to institute proceedings referred to in Section 5.07(2) or (iv) any direction referred to in Section 5.12, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06.
With respect to any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date.
Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.
In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.
Section 1.07.     Conflict with Trust Indenture Act.
If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act which is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.
Section 1.08.     Effect of Headings and Table of Contents.
The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.
Section 1.09.     Successors and Assigns.
All covenants and agreements in this Indenture by the Company and any Subsidiary Guarantor shall bind their respective successors and assigns, whether so expressed or not.
Section 1.10.     Separability Clause.
In case any provision in this Indenture, the Securities or the Subsidiary Guarantees shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 1.13.     Legal Holidays.
In any case where any Interest Payment Date, Redemption Date, purchase date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities (other than a provision of any Security which specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date, Redemption Date or purchase date, or at the Stated Maturity.
Section 1.14.     No Recourse Against Others.
No director, officer, employee, incorporator, stockholder, member, partner or trustee of the Company or any Subsidiary Guarantor, as such, shall have any liability for any obligations of the Company or any Subsidiary Guarantor under the Securities, this Indenture or any Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. By accepting a Security, each Holder shall be deemed to have waived and released all such liability. The waiver and release shall be a part of the consideration for the issue of the Securities. The waiver may not be effective to waive liabilities under the federal securities laws, and it is the view of the Commission that such a waiver is against public policy
Section 1.15.     Indenture May Be Executed in Counterparts.
The parties may sign any number of copies of this Indenture, and each party hereto may sign any number of separate copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

The Securities shall be executed on behalf of the Company by its Chairman of the Board of Directors, its Chief Executive Officer, President or one of its Executive Vice Presidents. If its corporate seal is reproduced thereon, then it shall be attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile.
Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.
At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company and, if applicable, having endorsed thereon the notations of Subsidiary Guarantees executed as provided in Section 13.03 by the Subsidiary Guarantors to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 2.01 and 3.01, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 6.01) shall be fully protected in relying upon, an Opinion of Counsel stating,
(1)     if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 2.01, that such form has been established in conformity with the provisions of this Indenture;
(2)     if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 3.01, that such terms have been established in conformity with the provisions of this Indenture; and

Notwithstanding the provisions of Section 3.01 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 3.01 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued.
    19

Exhibit 4.2
Each Security shall be dated the date of its authentication.
No Security or Subsidiary Guarantee shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.09, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

Neither the Company nor the Trustee shall have any responsibility for any defect in the CUSIP number that appears on any Security, check, advice of payment or redemption notice, and any such document may contain a statement to the effect that CUSIP numbers have been assigned by an independent service for convenience of reference and that neither the Company nor the Trustee shall be liable for any inaccuracy in such numbers.
Section 3.04.     Temporary Securities.
Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities and, if applicable, having endorsed thereon the notations of Subsidiary Guarantees in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities and, if applicable, notations of Subsidiary Guarantees may determine, as evidenced by their execution of such Securities and notations of Subsidiary Guarantees.
If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount and, if applicable, having endorsed thereon the notations of Subsidiary Guarantees executed by the Subsidiary Guarantors. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor.
Section 3.05.     Registration, Registration of Transfer and Exchange.
The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided.
Upon surrender for registration of transfer of any Security of a series at the office or agency of the Company in a Place of Payment for that series, the Company shall execute, if applicable the Subsidiary Guarantors shall execute the notations of Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount.
At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the
    20

Exhibit 4.2
Company shall execute, if applicable the Subsidiary Guarantors shall execute the notations of Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.
All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.
Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.
No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.04, 9.06, 11.07 or otherwise not involving any transfer.
If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for redemption under Section 11.03 and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.
The provisions of clauses (1), (2), (3) and (4) below shall apply only to Global Securities:
(1)     Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture.
(2)     Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act, and in either case the Company fails to appoint a successor Depositary within 90 days, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security and the Depositary shall have notified the Trustee of its decision to exchange such Global Security for Securities in certificated form, (C) subject to the rules of the Depositary, the Company shall have elected to terminate the book-entry system through the Depositary or (D) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated by Section 3.01.
(3)     Subject to clause (2) above, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct.
(4)     Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 3.04, 3.06, 9.06 or 11.07 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.
Section 3.06.     Mutilated, Destroyed, Lost and Stolen Securities.
    21

Exhibit 4.2
If any mutilated Security is surrendered to the Trustee, the Company shall execute, and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding and, if applicable the Subsidiary Guarantors shall execute the notation of Subsidiary Guarantee endorsed thereon.
If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless from any loss that any of them may suffer if a Security is replaced, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a protected purchaser, the Company shall execute, and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding and, if applicable the Subsidiary Guarantors shall execute the notation of Subsidiary Guarantee endorsed thereon.
In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable or is to be converted, the Company in its discretion may, instead of issuing a new Security, pay or authorize the conversion of such Security (without surrender thereof save in the case of a mutilated Security).
Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.
Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.
The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement, payment or conversion of mutilated, destroyed, lost or stolen Securities.
Section 3.07.     Payment of Interest; Interest Rights Preserved.
Except as otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.
Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:
(1)     The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the
    22

Exhibit 4.2
Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 1.06, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).
(2)    The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.
Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.
Section 3.08.     Persons Deemed Owners.
Prior to due presentment of a Security for registration of transfer, the Company, the Subsidiary Guarantors, the Trustee and any agent of the Company, the Subsidiary Guarantors, or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 3.07) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, any Subsidiary Guarantor, the Trustee nor any agent of the Company, any Subsidiary Guarantor, or the Trustee shall be affected by notice to the contrary.
Section 3.09.     Cancellation.
All Securities surrendered for payment, redemption, purchase, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of in accordance with its standard procedures, unless as directed by a Company Order.
Section 3.10.     Computation of Interest.
Except as otherwise specified as contemplated by Section 3.01 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

(2)     the Company or a Subsidiary Guarantor has paid or caused to be paid all other sums payable hereunder by the Company and the Subsidiary Guarantors with respect to the Securities of such series; and
(3)     the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to the Securities of such series have been complied with.
Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 6.07, the obligations of the Company with respect to the Securities of such series under Sections 3.04, 3.05, 3.06, 10.02 and 10.03, any surviving rights of conversion, the obligations of the Trustee to any Authenticating Agent under Section 6.14 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under Section 4.02 and the last paragraph of Section 10.03 shall survive.
Section 4.02.     Application of Trust Money.
Subject to the provisions of the last paragraph of Section 10.03, all money deposited with the Trustee pursuant to Section 4.01 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and any premium and interest for whose payment such money has been deposited with the Trustee.
ARTICLE FIVE

Section 5.01.     Events of Default.
“Event of Default,” wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

Section 5.02.     Acceleration of Maturity; Rescission and Annulment.
If an Event of Default (other than an Event of Default with respect to the Company specified in Section 5.01(8) or 5.01(9)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount), together with any accrued and unpaid interest thereon, shall become immediately due and payable. If an Event of Default with respect to the Company specified in Section 5.01(8) or 5.01(9) with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof), together with any accrued and unpaid interest thereon, shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable.
At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if
(1)     the Company or, if applicable, any Subsidiary Guarantor has paid or deposited with the Trustee a sum sufficient to pay
(A)     all overdue interest on all Securities of that series,
(B)     the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities,
(C)     to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and
(D)     all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel;
    26

Exhibit 4.2
and
(2)     all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series which has become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13.
No such rescission shall affect any subsequent default or impair any right consequent thereon.
Section 5.03.     Collection of Indebtedness and Suits for Enforcement by Trustee.
The Company covenants that if
(1)     default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or
(2)     default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof,
the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.
If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.
Section 5.04.     Trustee May File Proofs of Claim.
In case of any judicial proceeding relative to the Company, any Subsidiary Guarantor or any other obligor upon the Securities, or the property or creditors of the Company, any Subsidiary Guarantor or any other obligor upon the Securities, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.07.
No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or any Subsidiary Guarantee or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.
Section 5.05.     Trustee May Enforce Claims Without Possession of Securities.
All rights of action and claims under this Indenture or the Securities or any Subsidiary Guarantee may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in
    27

Exhibit 4.2
any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.
Section 5.06.     Application of Money Collected.
Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or any premium or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:
FIRST: To the payment of all amounts due the Trustee under Section 6.07;
SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and any premium and interest, respectively; and
THIRD: The balance, if any, to the Company or to such other Person as a court of competent jurisdiction shall direct.
Section 5.07.     Limitation on Suits.
Subject to Section 5.08 hereof, no Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless
(1)     such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series;
(2)     the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;
(3)     such Holder or Holders have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities to be incurred in compliance with such request;
(4)     the Trustee for 60 days after its receipt of such notice, request and offer of security or indemnity has failed to institute any such proceeding; and
(5)     no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series;
it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders.
Section 5.08.     Unconditional Contractual Right of Holders to Receive Principal, Premium and Interest.
Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the contractual right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 3.07) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption or offer by the Company to purchase the Securities pursuant to the terms of this Indenture, on the Redemption Date or purchase date, as applicable) and, if applicable, to convert such Security in accordance with its
    28

Exhibit 4.2
terms, and to institute suit for the enforcement of any such right, and such rights shall not be impaired without the consent of such Holder.
Section 5.09.     Restoration of Rights and Remedies.
If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Subsidiary Guarantors, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.
Section 5.11.     Delay or Omission Not Waiver.
No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.
Section 5.12.     Control by Holders.
The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that
(1)     such direction shall not be in conflict with any rule of law or with this Indenture, and
(2)     the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.
Section 5.13.     Waiver of Past Defaults.
The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except a default
(1)     in the payment of the principal of or any premium or interest on any Security of such series (including any Security which is required to have been purchased by the Company pursuant to an offer to purchase by the Company made pursuant to the terms of this Indenture), or
(2)     in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.
Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.
    29

Exhibit 4.2
Section 5.14.     Undertaking for Costs.
In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided, however, that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company or any Subsidiary Guarantor.
Section 5.15.     Waiver of Usury, Stay or Extension Laws.
Each of the Company and the Subsidiary Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and each of the Company and the Subsidiary Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.
ARTICLE SIX
THE TRUSTEE
Section 6.01.     Certain Duties and Responsibilities.
The duties and responsibilities of the Trustee shall be as expressly set forth in this Indenture and as provided by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section.
Section 6.02.     Notice of Defaults.
If a default occurs hereunder with respect to Securities of any series, the Trustee shall give the Holders of Securities of such series notice of such default as and to the extent provided by the Trust Indenture Act; provided, however, that in the case of any default of the character specified in Section 5.01(5) with respect to Securities of such series, no such notice to Holders shall be given until at least 30 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to Securities of such series.
Section 6.03.     Certain Rights of Trustee.
Subject to the provisions of Section 6.01:
(1)     the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;
(2)     any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order, and any resolution of the Board of Directors shall be sufficiently evidenced by a Board Resolution;
    30

Exhibit 4.2
(3)     whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate;
(4)     the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;
(5)     the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction;
(6)    the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; and
(7)     the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder.
Section 6.04.     Not Responsible for Recitals or Issuance of Securities.
The recitals contained herein and in the Securities and the notations of Subsidiary Guarantees, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company or the Subsidiary Guarantors, as the case may be, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities or the Subsidiary Guarantees. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof.
Section 6.05.     May Hold Securities.
The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company or any Subsidiary Guarantor, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 6.08 and 6.13, may otherwise deal with the Company and any Subsidiary Guarantor with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

Subject to the limitations imposed by the Trust Indenture Act, nothing in this Indenture shall prohibit the Trustee from becoming and acting as trustee under other indentures under which other securities, or certificates of interest of participation in other securities, of the Company are outstanding in the same manner as if it were not Trustee hereunder.
Section 6.06.     Money Held in Trust.
Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company or any Subsidiary Guarantor, as the case may be.
Section 6.07.     Compensation and Reimbursement.
The Company and each Subsidiary Guarantor jointly and severally agree
    31

Exhibit 4.2
(1)     to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);
(2)    except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and
(3)     to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 5.1(5) or Section 5.1(6) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any applicable bankruptcy, insolvency, reorganization or similar law.
Section 6.08.     Conflicting Interests.
If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series.
Section 6.09.     Corporate Trustee Required; Eligibility.
There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, and has a combined capital and surplus of at least $50,000,000. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.
Section 6.10.     Resignation and Removal; Appointment of Successor.
No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.11.
The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.
The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company.
    32

Exhibit 4.2
If at any time:
(1)     the Trustee shall fail to comply with Section 6.08 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or
(2)     the Trustee shall cease to be eligible under Section 6.09 and shall fail to resign after written request therefor by the Company or by any such Holder, or
(3)     the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,
then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to Section 5.14, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.
If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 6.11. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 6.11, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 6.11, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.
The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 1.06. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.
Section 6.11.     Acceptance of Appointment by Successor.
In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company, the Subsidiary Guarantors and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.
In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the Subsidiary Guarantors, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be
    33

Exhibit 4.2
necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.
Upon request of any such successor Trustee, the Company and the Subsidiary Guarantors shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be.
No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.
Section 6.12.     Merger, Conversion, Consolidation or Succession to Business.
Any Person into which the Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such Person shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. As soon as practicable, the successor Trustee shall mail a notice of its succession to the Company and the Holders of the Securities then Outstanding. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.
Section 6.13.     Preferential Collection of Claims Against Company and Subsidiary Guarantors.
If and when the Trustee shall be or become a creditor of the Company, any Subsidiary Guarantor or any other obligor upon the Securities, the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company, such Subsidiary Guarantor or any such other obligor.
Section 6.14.     Appointment of Authenticating Agent.
The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer, conversion or partial redemption thereof or pursuant to Section 3.06, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a Person organized and doing
    34

Exhibit 4.2
business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.
Any Person into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any Person succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such Person shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.
An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment in the manner provided in Section 1.06 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.
The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 6.07.
If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

(1)     change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof, or reduce the amount of the principal of an Original Issue Discount Security or any other Security which would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 5.02, or change any Place of Payment where, or the coin or currency in which, any Security or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of (a) any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date or in the case of an offer to purchase Securities which has been made pursuant to a covenant contained in this Indenture, on or after the applicable purchase date) or (b) any conversion right with respect to any Security, or modify the provisions of this Indenture with respect to the conversion of the Securities, in a manner adverse to the Holders, or release any Subsidiary Guarantee other than as provided in this Indenture; or
(2)     reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture; or
(3)    modify any of the provisions of this Section, Section 5.13 or Section 10.09, except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; provided, however, that this clause shall not be deemed to require the consent of any Holder with respect to changes in the references to “the Trustee” and concomitant changes in this Section and Section 10.09, or the deletion of this proviso, in accordance with the requirements of Sections 6.11 and 9.01(8); or
(4)     following the making of an offer to purchase Securities from any Holder which has been made pursuant to a covenant contained in this Indenture, modify the provisions of this Indenture with respect to such offer to purchase in a manner adverse to such Holder.
A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series.

Exhibit 4.2
It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.
After a supplemental indenture under this Section 9.02 requiring the consent of the Holders of any series of Securities is approved, the Company shall mail to Holders of that series of Securities a notice briefly describing any amendment or supplement hereto effected by such supplemental indenture. The failure to give such notice to any such Holders, or any defect therein, shall not impair or affect the validity of any amendment or supplement hereto effected by such supplemental indenture with respect to other Holders.
Section 9.03.     Execution of Supplemental Indentures.
In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 6.01) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.
Section 9.04.     Effect of Supplemental Indentures.

Securities of any series authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company, if applicable the notations of Subsidiary Guarantees may be endorsed thereon and such new Securities may be authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series.

COVENANTS
Section 10.01.     Payment of Principal, Premium and Interest.
The Company covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay the principal of and any premium and interest on the Securities of that series in accordance with the terms of the Securities and this Indenture. Principal, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 11:00 A.M., New York City time, on the due date money deposited with it in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due.
Section 10.02.     Maintenance of Office or Agency.
    40

Exhibit 4.2
The Company will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment or, if applicable, for conversion, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company or any Subsidiary Guarantor in respect of the Securities of that series or any Subsidiary Guarantee and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and each of the Company and the Subsidiary Guarantors hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.
The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.
Section 10.03.     Money for Securities Payments to be Held in Trust.
If the Company or any Subsidiary Guarantor shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.
Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, prior to 11:00 A.M., New York City time, on each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.
The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Company, the Subsidiary Guarantors, if applicable, or any other obligor upon the Securities of that series in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series.
The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.
Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general
    41

Exhibit 4.2
circulation in The City of New York, New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

(a)     The Company and the Subsidiary Guarantors will deliver to the Trustee, within 90 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company or any Subsidiary Guarantor, as the case may be, is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company or any Subsidiary Guarantor shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge.
(b)     The Company shall, so long as any series of Securities is Outstanding, deliver to the Trustee, as soon as possible and in any event within five days after the Company becomes aware of the occurrence of an Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’ Certificate setting forth the details of such Event of Default or default, and the action which the Company proposes to take with respect thereto.
Section 10.05.     Existence.
Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect the existence, rights (charter and statutory) and franchises of the Company; provided, however, that the Company shall not be required to preserve any such right or franchise if it shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders.
Section 10.06.     Maintenance of Properties.
The Company will cause all properties used or useful in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order (reasonable wear and tear excepted) and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any Subsidiary and not disadvantageous in any material respect to the Holders.
Section 10.07.     Payment of Taxes and Other Claims.
The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and (2) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings.
Section 10.08.     Maintenance of Insurance.
The Company shall, and shall cause its Subsidiaries to, keep at all times all of their properties which are of an insurable nature insured against loss or damage with insurers believed by the Company to be responsible to the
    42

Exhibit 4.2
extent that property of similar character is usually so insured by corporations similarly situated and owning like properties in accordance with good business practice.
Section 10.09.     Waiver of Certain Covenants.
Except as otherwise specified as contemplated by Section 3.01 for Securities of such series, the Company and the Subsidiary Guarantors may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any of Sections 10.05 through 10.08 or in any covenant provided pursuant to Section 3.01(21), 9.01(2) or 9.01(5) or (7) for the benefit of the Holders of such series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.
ARTICLE ELEVEN
REDEMPTION OF SECURITIES
Section 11.01.     Applicability of Article.
Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 3.01 for such Securities) in accordance with this Article.
Section 11.02.     Election to Redeem; Notice to Trustee.
The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 3.01 for such Securities.
In case of any redemption at the election of the Company of less than all the Securities of any series (including any such redemption affecting only a single Security), the Company shall, at least five Business Days prior to giving notice of such redemption (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction.
Section 11.03.     Selection by Trustee of Securities to be Redeemed.
If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected by the Trustee, from the Outstanding Securities of such series not previously called for redemption, (i) in compliance with the requirements of the principal national securities exchange on which such Securities are listed, if such Securities are listed on any national securities exchange, and (ii) if such Securities are not so listed, on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of a portion of the principal amount of any Security of such series, provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected by the Trustee, from the
    43

Exhibit 4.2
Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with the preceding sentence.
The Trustee shall promptly notify the Company in writing of the Securities selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, the principal amount thereof to be redeemed.
The provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security.
For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. If any Security selected for partial redemption is surrendered for conversion after such selection, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Upon any redemption of less than all the Securities of a series, for purposes of selection for redemption the Company and the Trustee may treat as Outstanding Securities surrendered for conversion during the period of 15 days next preceding the mailing of a notice of redemption, and need not treat as Outstanding any Security authenticated and delivered during such period in exchange for the unconverted portion of any Security converted in part during such period.
Section 11.04.     Notice of Redemption.
Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register; provided, however, notice of redemption may be given more than 60 days prior to the Redemption Date if the notice is issued in connection with a satisfaction and discharge pursuant to Article Four.
All notices of redemption shall state:
(1)     the Redemption Date,
(2)     the Redemption Price, if then determinable and otherwise the method of its determination,
(3)     if less than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed, the identification (and, in the case of partial redemption of any such Securities, the principal amounts) of the particular Securities to be redeemed and, if less than all the Outstanding Securities of any series consisting of a single Security are to be redeemed, the principal amount of the particular Security to be redeemed,
(4)     that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,
(5)     the place or places where each such Security is to be surrendered for payment of the Redemption Price,
(6)     that the redemption is for a sinking fund, if such is the case; and
(7)     if applicable, the conversion price then in effect and the date on which the right to convert such Securities will expire.
Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company and shall be irrevocable. If any Security called for redemption is converted pursuant hereto, any money deposited with the Trustee or any Paying Agent or so segregated and held in trust for the redemption of such Security shall be paid to
    44

Exhibit 4.2
the Company upon delivery of a Company Request to the Trustee or such Paying Agent, or, if then held by the Company, shall be discharged from such trust.
Section 11.05.     Deposit of Redemption Price.
Prior to 11:00 A.M., New York City time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.03) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date.
Section 11.06.     Securities Payable on Redemption Date.
Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 3.01, installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.07.
If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security.
Section 11.07.     Securities Redeemed in Part.
Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, if applicable, the Subsidiary Guarantors shall execute the notations of Subsidiary Guarantees endorsed thereon, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

SUBSIDIARY GUARANTEES
Section 13.01.     Applicability of Article.
Unless the Company elects to issue any series of Securities without the benefit of the Subsidiary Guarantees, which election shall be evidenced in or pursuant to the Board Resolution or supplemental indenture establishing such series of Securities pursuant to Section 3.01, the provisions of this Article shall be applicable to each series of Securities except as otherwise specified in or pursuant to the Board Resolution or supplemental indenture establishing such series pursuant to Section 3.01.
    45

Exhibit 4.2
Section 13.02.     Subsidiary Guarantees.
Subject to Section 13.01, each Subsidiary Guarantor hereby, jointly and severally, fully and unconditionally guarantees to each Holder of a Security authenticated and delivered by the Trustee, the due and punctual payment of the principal of (and premium, if any) and interest on such Security when and as the same shall become due and payable, whether at the Stated Maturity, by acceleration, call for redemption, offer to purchase or otherwise, in accordance with the terms of such Security and of this Indenture, and each Subsidiary Guarantor similarly guarantees to the Trustee the payment of all amounts owing to the Trustee in accordance with the terms of this Indenture. In case of the failure of the Company punctually to make any such payment, each Subsidiary Guarantor hereby, jointly and severally, agrees to cause such payment to be made punctually when and as the same shall become due and payable, whether at the Stated Maturity or by acceleration, call for redemption, offer to purchase or otherwise, and as if such payment were made by the Company.
Each of the Subsidiary Guarantors hereby jointly and severally agrees that its obligations hereunder shall be absolute, unconditional, irrespective of, and shall be unaffected by, the validity, regularity or enforceability of such Security or this Indenture, the absence of any action to enforce the same or any release, amendment, waiver or indulgence granted to the Company or any other guarantor or any consent to departure from any requirement of any other guarantee of all or any of the Securities of such series or any other circumstances which might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor; provided, however, that, notwithstanding the foregoing, no such release, amendment, waiver or indulgence shall, without the consent of such Subsidiary Guarantor, increase the principal amount of such Security, or increase the interest rate thereon, or alter the Stated Maturity thereof. Each of the Subsidiary Guarantors hereby waives the benefits of diligence, presentment, demand for payment, any requirement that the Trustee or any of the Holders protect, secure, perfect or insure any security interest in or other lien on any property subject thereto or exhaust any right or take any action against the Company or any other Person or any collateral, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to such Security or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this Subsidiary Guarantee will not be discharged in respect of such Security except by complete performance of the obligations contained in such Security and in such Subsidiary Guarantee. Each Subsidiary Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Securities of a series, to collect interest on the Securities of a series, or to enforce or exercise any other right or remedy with respect to the Securities of a series, such Subsidiary Guarantor agrees to pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.
Each Subsidiary Guarantor shall be subrogated to all rights of the Holders of the Securities upon which its Subsidiary Guarantee is endorsed against the Company in respect of any amounts paid by such Subsidiary Guarantor on account of such Security pursuant to the provisions of its Subsidiary Guarantee or this Indenture; provided, however, that no Subsidiary Guarantor shall be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until the principal of (and premium, if any) and interest on all Securities of the relevant series issued hereunder shall have been paid in full.
Each Subsidiary Guarantor that makes or is required to make any payment in respect of its Subsidiary Guarantee shall be entitled to seek contribution from the other Subsidiary Guarantors to the extent permitted by applicable law; provided, however, that no Subsidiary Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of contribution until the principal of (and premium, if any) and interest on all Securities of the relevant series issued hereunder shall have been paid in full.
Each Subsidiary Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Securities of a series, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any Holder of the Securities, whether
    46

Exhibit 4.2
as a “voidable preference,” “fraudulent transfer,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Securities shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.
Section 13.03.     Execution and Delivery of Notations of Subsidiary Guarantees.
To further evidence the Subsidiary Guarantee set forth in Section 13.02, each of the Subsidiary Guarantors hereby agrees that a notation relating to such Subsidiary Guarantee, substantially in the form set forth in Section 2.04, shall be endorsed on each Security entitled to the benefits of the Subsidiary Guarantee authenticated and delivered by the Trustee and executed by either manual or facsimile signature of an officer of such Subsidiary Guarantor, or in the case of a Subsidiary Guarantor that is a limited partnership, an officer of the general partner of each Subsidiary Guarantor. Each of the Subsidiary Guarantors hereby agrees that the Subsidiary Guarantee set forth in Section 13.02 shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation relating to the Subsidiary Guarantee. If any officer of the Subsidiary Guarantor, or in the case of a Subsidiary Guarantor that is a limited partnership, any officer of the general partner of the Subsidiary Guarantor, whose signature is on this Indenture or a Security no longer holds that office at the time the Trustee authenticates such Security or at any time thereafter, the Subsidiary Guarantee of such Security shall be valid nevertheless. The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantors.
Section 13.04.     Release of Subsidiary Guarantors.
Unless otherwise specified pursuant to Section 3.01 with respect to a series of Securities, each Subsidiary Guarantee will remain in effect with respect to the respective Subsidiary Guarantor until the entire principal of, premium, if any, and interest on the Securities to which such Subsidiary Guarantee relates shall have been paid in full or otherwise satisfied and discharged in accordance with the provisions of such Securities and this Indenture and all amounts owing to the Trustee hereunder have been paid; provided, however, that if (i) such Subsidiary Guarantor ceases to be a Subsidiary in compliance with the applicable provisions of this Indenture, (ii) either Defeasance or Covenant Defeasance occurs with respect to such Securities pursuant to Article Fifteen or (iii) all or substantially all of the assets of such Subsidiary Guarantor or all of the Capital Stock of such Subsidiary Guarantor is sold (including by sale, merger, consolidation or otherwise) by the Company or any Subsidiary in a transaction complying with the requirements of this Indenture, then, in each case of (i), (ii) or (iii), upon delivery by the Company of an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent herein provided for relating to the release of such Subsidiary Guarantor from its obligations under its Subsidiary Guarantee and this Article Thirteen have been complied with, such Subsidiary Guarantor shall be released and discharged of its obligations under its Subsidiary Guarantee and under this Article Thirteen without any action on the part of the Trustee or any Holder, and the Trustee shall execute any documents reasonably required in order to acknowledge the release of such Subsidiary Guarantor from its obligations under its Subsidiary Guarantee endorsed on the Securities of such series and under this Article Thirteen.
Section 13.05.     Additional Subsidiary Guarantors.
Unless otherwise specified pursuant to Section 3.01 with respect to a series of Securities, the Company will cause any domestic Wholly Owned Subsidiary of the Company that becomes a Subsidiary after the date the Securities of a series are first issued hereunder to become a Subsidiary Guarantor as soon as practicable after such Subsidiary becomes a Subsidiary. The Company shall cause any such Wholly Owned Subsidiary to become a Subsidiary Guarantor with respect to the Securities by executing and delivering to the Trustee (a) a supplemental indenture, in form and substance satisfactory to the Trustee, which subjects such Person to the provisions (including the representations and warranties) of this Indenture as a Subsidiary Guarantor and (b) an Opinion of Counsel to the effect that such supplemental indenture has been duly authorized and executed by such Person and such supplemental indenture and such Person’s obligations under its Subsidiary Guarantee and this Indenture constitute the legal, valid, binding and enforceable obligations of such Person (subject to such customary exceptions concerning creditors’ rights and equitable principles as may be acceptable to the Trustee in its discretion).
    47

Exhibit 4.2
Section 13.06.     Limitation on Liability.
Any term or provision of this Indenture to the contrary notwithstanding, the maximum amount of the Subsidiary Guarantee of any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed by such Subsidiary Guarantor without rendering such Subsidiary Guarantee voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

The Company may elect, at its option at any time, to have Section 15.02 or Section 15.03 applied to any Securities or any series of Securities, as the case may be, designated pursuant to Section 3.01 as being defeasible pursuant to such Section 15.02 or 15.03, in accordance with any applicable requirements provided pursuant to Section 3.01 and upon compliance with the conditions set forth below in this Article. Any such election shall be evidenced in or pursuant to a Board Resolution or in another manner specified as contemplated by Section 3.01 for such Securities.
Section 15.02.     Defeasance and Discharge.
Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, the Company shall be deemed to have been discharged from its obligations, and each Subsidiary Guarantor shall be deemed to have been discharged from its obligations with respect to its Subsidiary Guarantee of such Securities, as provided in this Section on and after the date the conditions set forth in Section 15.04 are satisfied (herein called “Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of such Securities to receive, solely from the trust fund described in Section 15.04 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities when payments are due, or, if applicable, to convert such Securities in accordance with their terms, (2) the Company’s and each Subsidiary Guarantor’s obligations with respect to such Securities under Sections 3.04, 3.05, 3.06, 10.02 and 10.03, and, if applicable, their obligations with respect to the conversion of such Securities, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article.

Exhibit 4.2
effective, in each case with respect to such Securities and Subsidiary Guarantees as provided in this Section on and after the date the conditions set forth in Section 15.04 are satisfied (herein called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to such Securities, the Company and the Subsidiary Guarantors, as applicable, may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case of Section 5.01(5)) or Article Thirteen, whether directly or indirectly by reason of any reference elsewhere herein to any such Section or Article or by reason of any reference in any such Section or Article to any other provision herein or in any other document, but the remainder of this Indenture and such Securities shall be unaffected thereby.
Section 15.04.     Conditions to Defeasance or Covenant Defeasance.
The following shall be the conditions to the application of Section 15.02 or Section 15.03 to any Securities or any series of Securities, as the case may be:
(1)     The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee which satisfies the requirements contemplated by Section 6.09 and agrees to comply with the provisions of this Article applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefits of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, in each case sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge, the principal of and any premium and interest on such Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. As used herein, “U.S. Government Obligation” means (x) any security which is (i) a direct obligation of the United States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable at the option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S. Government Obligation which is specified in clause (x) above and held by such bank for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so specified and held, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal or interest evidenced by such depositary receipt.
(2)     In the event of an election to have Section 15.02 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this instrument, there has been a change in the applicable Federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Defeasance were not to occur.
(3)     In the event of an election to have Section 15.03 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur.
    49

Exhibit 4.2
(4)     The Company shall have delivered to the Trustee an Officers’ Certificate to the effect that neither such Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit.
(5)     No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to such Securities shall have occurred and be continuing at the time of such deposit (other than a default or an Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Debt) and the granting of liens to secure such borrowing) or, with regard to any such event specified in Sections 5.01(7) and (8), at any time on or prior to the 121st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 121st day).
(6)     Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act).
(7)     Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company or any Subsidiary is a party or by which it is bound.
(8)    The Company shall have delivered to the Trustee an Opinion of Counsel to the effect that such deposit shall not cause either the Trustee or the trust so created to be subject to the Investment Company Act of 1940.
(9)     The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with.
Section 15.05.     Deposited Money and U.S. Government Obligations to be Held in Trust; Miscellaneous Provisions.
Subject to the provisions of the last paragraph of Section 10.03, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 15.06, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 15.04 in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other funds except to the extent required by law.
The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 15.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of Outstanding Securities.
Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 15.04 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities.
Section 15.06.     Reinstatement.
If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities
    50

Exhibit 4.2
from which the Company has been discharged or released pursuant to Section 15.02 or 15.03 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 15.05 with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust.
ARTICLE SIXTEEN
SINKING FUNDS
Section 16.01.     Applicability of Article.
The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of any series except as otherwise specified as contemplated by Section 3.01 for such Securities.
The minimum amount of any sinking fund payment provided for by the terms of any Securities is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of such Securities is herein referred to as an “optional sinking fund payment.” If provided for by the terms of any Securities, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 16.02. Each sinking fund payment shall be applied to the redemption of Securities as provided for by the terms of such Securities.
Section 16.02.     Satisfaction of Sinking Fund Payments with Securities.
The Company (1) may deliver Outstanding Securities of a series (other than any previously called for redemption) and (2) may apply as a credit Securities of a series which have been (x) converted or (y) redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to any Securities of such series required to be made pursuant to the terms of such Securities as and to the extent provided for by the terms of such Securities; provided, however, that the Securities to be so credited have not been previously so credited. The Securities to be so credited shall be received and credited for such purpose by the Trustee at the Redemption Price, as specified in the Securities so to be redeemed, for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly.
Section 16.03.     Redemption of Securities for Sinking Fund.
Not less than 35 days prior to each sinking fund payment date for any Securities, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities pursuant to Section 16.02 and will also deliver to the Trustee any Securities to be so delivered. Not less than 32 days prior to each such sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 11.03 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 11.04. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 11.06 and 11.07.
This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.

Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority.

The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series, provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken.

If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06.
With respect to any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set
    8

Exhibit 4.4
forth in Section 1.06, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date.
Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.
In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.
Section 1.07.     Conflict with Trust Indenture Act.
If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act which is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium

Sections 2.01 and 3.01, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 6.01) shall be fully protected in relying upon, an Opinion of Counsel stating,

No Security or Subsidiary Guarantee shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.09, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount and, if applicable, having endorsed thereon the notations of Subsidiary Guarantees executed by the Subsidiary Guarantors.

The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided.
Upon surrender for registration of transfer of any Security of a series at the office or agency of the Company in a Place of Payment for that series, the Company shall execute, if applicable the Subsidiary Guarantors shall execute the notations of Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount.
At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, if applicable the Subsidiary Guarantors shall execute the notations of Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.
All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.
Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.
No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.04, 9.06, 11.07 or otherwise not involving any transfer.
    21

Exhibit 4.4
If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for redemption under Section 11.03 and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.
The provisions of clauses (1), (2), (3) and (4) below shall apply only to Global Securities:
(1)     Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture.
(2)     Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act, and in either case the Company fails to appoint a successor Depositary within 90 days, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security and the Depositary shall have notified the Trustee of its decision to exchange such Global Security for Securities in certificated form, (C) subject to the rules of the Depositary, the Company shall have elected to terminate the book-entry system through the Depositary or (D) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated by Section 3.01.
(3)     Subject to clause (2) above, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct.
(4)     Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 3.04, 3.06, 9.06 or 11.07 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.
Section 3.06.     Mutilated, Destroyed, Lost and Stolen Securities.
If any mutilated Security is surrendered to the Trustee, the Company shall execute, and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding and, if applicable the Subsidiary Guarantors shall execute the notation of Subsidiary Guarantee endorsed thereon.
If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless from any loss that any of them may suffer if a Security is replaced, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a protected purchaser, the Company shall execute, and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding and, if applicable the Subsidiary Guarantors shall execute the notation of Subsidiary Guarantee endorsed thereon.
In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable or is to be converted, the Company in its discretion may, instead of issuing a new Security, pay or authorize the conversion of such Security (without surrender thereof save in the case of a mutilated Security).
    22

Exhibit 4.4
Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.
Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.
The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement, payment or conversion of mutilated, destroyed, lost or stolen Securities.
Section 3.07.     Payment of Interest; Interest Rights Preserved.
Except as otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.
Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:
(1)     The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 1.06, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).
(2)     The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.
Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.
Section 3.08.     Persons Deemed Owners.
    23

Exhibit 4.4
Prior to due presentment of a Security for registration of transfer, the Company, the Subsidiary Guarantors, the Trustee and any agent of the Company, the Subsidiary Guarantors, or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 3.07) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, any Subsidiary Guarantor, the Trustee nor any agent of the Company, any Subsidiary Guarantor, or the Trustee shall be affected by notice to the contrary.

Section 3.09.     Cancellation.
    All Securities surrendered for payment, redemption, purchase, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of in accordance with its standard procedures, unless as directed by a Company Order.
Section 3.10.     Computation of Interest.
Except as otherwise specified as contemplated by Section 3.01 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

(2)     the Company or a Subsidiary Guarantor has paid or caused to be paid all other sums payable hereunder by the Company and the Subsidiary Guarantors with respect to the Securities of such series; and

ARTICLE FIVE

Section 5.01.     Events of Default.
“Event of Default,” wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be occasioned by the provisions of Article Twelve or be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

If an Event of Default (other than an Event of Default with respect to the Company specified in Section 5.01(8) or 5.01(9)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount), together with any accrued and unpaid interest thereon, shall become immediately due and payable. If an Event of Default with respect to the Company specified in Section 5.01(8) or 5.01(9) with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof), together with any accrued and unpaid interest thereon, shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable.
At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if

(A)     all overdue interest on all Securities of that series,
(B)     the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities,

(D)     all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel;
and
(2)     all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series which has become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13.
No such rescission shall affect any subsequent default or impair any right consequent thereon.

(1)     default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or
(2)     default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof,
the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.
If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.
Section 5.04.     Trustee May File Proofs of Claim.
In case of any judicial proceeding relative to the Company, any Subsidiary Guarantor or any other obligor upon the Securities, or the property or creditors of the Company, any Subsidiary Guarantor or any other obligor upon the Securities, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.07.
No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or any Subsidiary Guarantee or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.
Section 5.05.     Trustee May Enforce Claims Without Possession of Securities.
All rights of action and claims under this Indenture or the Securities or any Subsidiary Guarantee may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

SECOND: Subject to Article Twelve and Article Fourteen, to the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and any premium and interest, respectively; and
THIRD: The balance, if any, to the Company or to such other Person as a court of competent jurisdiction shall direct.

(5)     no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series;
it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders.
Section 5.08.     Unconditional Contractual Right of Holders to Receive Principal, Premium and Interest.
Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the contractual right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 3.07) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption or offer by the Company to purchase the Securities pursuant to the terms of this Indenture, on the Redemption Date or purchase date, as applicable) and, if applicable, to convert such Security in accordance with its terms, and to institute suit for the enforcement of any such right, and such rights shall not be impaired without the consent of such Holder.
Section 5.09.     Restoration of Rights and Remedies.
If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such
    29

The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.
Section 5.11.     Delay or Omission Not Waiver.
No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.

(1)     in the payment of the principal of or any premium or interest on any Security of such series (including any Security which is required to have been purchased by the Company pursuant to an offer to purchase by the Company made pursuant to the terms of this Indenture), or
(2)     in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series.

Each of the Company and the Subsidiary Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and each of the Company and the Subsidiary Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

(6)     the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; and

Section 6.04.     Not Responsible for Recitals or Issuance of Securities.
The recitals contained herein and in the Securities and the notations of Subsidiary Guarantees, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company or the Subsidiary Guarantors, as the case may be, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities or the Subsidiary Guarantees. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof.
Section 6.05.     May Hold Securities.
The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company or any Subsidiary Guarantor, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 6.08 and 6.13, may otherwise deal with the Company and any Subsidiary Guarantor with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.
Section 6.06.     Money Held in Trust.
Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company or any Subsidiary Guarantor, as the case may be.
Section 6.07.     Compensation and Reimbursement.
The Company and each Subsidiary Guarantor jointly and severally agree
(1)     to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

Section 6.08.     Conflicting Interests.
If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series.
Section 6.09.     Corporate Trustee Required; Eligibility.
There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, and has a combined capital and surplus of at least $50,000,000. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.
Section 6.10.     Resignation and Removal; Appointment of Successor.
No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.11.
The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.
The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company.
If at any time:
(1)     the Trustee shall fail to comply with Section 6.08 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or
(2)     the Trustee shall cease to be eligible under Section 6.09 and shall fail to resign after written request therefor by the Company or by any such Holder, or
(3)     the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,
    33

Exhibit 4.4
then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to Section 5.14, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.
If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 6.11. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 6.11, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 6.11, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.
The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 1.06. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.
Section 6.11.     Acceptance of Appointment by Successor.
In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company, the Subsidiary Guarantors and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.
In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the Subsidiary Guarantors, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested
    34

Exhibit 4.4
with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.
Upon request of any such successor Trustee, the Company and the Subsidiary Guarantors shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be.
No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.
Section 6.12.     Merger, Conversion, Consolidation or Succession to Business.
Any Person into which the Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such Person shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. As soon as practicable, the successor Trustee shall mail a notice of its succession to the Company and the Holders of the Securities then Outstanding. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.
Section 6.13.     Preferential Collection of Claims Against Company and Subsidiary Guarantors.
If and when the Trustee shall be or become a creditor of the Company, any Subsidiary Guarantor or any other obligor upon the Securities, the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company, such Subsidiary Guarantor or any such other obligor.
Section 6.14.     Appointment of Authenticating Agent.
The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer, conversion or partial redemption thereof or pursuant to Section 3.06, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a Person organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.
Any Person into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any Person succeeding to the corporate agency or corporate trust business of an
    35

Exhibit 4.4
Authenticating Agent, shall continue to be an Authenticating Agent, provided such Person shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.
An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment in the manner provided in Section 1.06 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.
The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 6.07.
If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:
This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

With the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of each series affected by such supplemental indenture, by Act of said Holders delivered to the Company, the Subsidiary Guarantors and the Trustee, the Company, when authorized by a Board Resolution, the Subsidiary Guarantors, when authorized by their respective Board Resolutions, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Security affected thereby:
(1)     change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof, or reduce the amount of the principal of an Original Issue Discount Security or any other Security which would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 5.02, or change any Place of Payment where, or the coin or currency in which, any Security or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of (a) any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date or in the case of an offer to purchase Securities which has been made pursuant to a covenant contained in this Indenture, on or after the applicable purchase date) or (b) any conversion right with respect to any Security, or modify the provisions of this Indenture with respect to the conversion or subordination of the Securities or the Subsidiary Guarantees, in a manner adverse to the Holders, or release any Subsidiary Guarantee other than as provided in this Indenture; or
(2)     reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture; or
(3)     modify any of the provisions of this Section, Section 5.13 or Section 10.09, except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; provided, however, that this clause shall not be deemed to require the consent of any Holder with respect to changes in the references to “the Trustee” and concomitant changes in this Section and Section 10.09, or the deletion of this proviso, in accordance with the requirements of Sections 6.11 and 9.01(8); or
(4)     following the making of an offer to purchase Securities from any Holder which has been made pursuant to a covenant contained in this Indenture, modify the provisions of this Indenture with respect to such offer to purchase in a manner adverse to such Holder.
A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series.
It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.
After a supplemental indenture under this Section 9.02 requiring the consent of the Holders of any series of Securities is approved, the Company shall mail to Holders of that series of Securities a notice briefly describing any amendment or supplement hereto effected by such supplemental indenture. The failure to give such notice to any such Holders, or any defect therein, shall not impair or affect the validity of any amendment or supplement hereto effected by such supplemental indenture with respect to other Holders.

ARTICLE TEN
COVENANTS
Section 10.01.     Payment of Principal, Premium and Interest.
The Company covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay the principal of and any premium and interest on the Securities of that series in accordance with the terms of the Securities and this Indenture. Principal, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 11:00 A.M., New York City time, on the due date money deposited with it in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due, and such Paying Agent is not prohibited from paying such money to the Holders entitled thereto on such date pursuant to the terms of Article Twelve or Article Fourteen of this Indenture.
Section 10.02.     Maintenance of Office or Agency.
The Company will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment or, if applicable, for conversion, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company or any Subsidiary Guarantor in respect of the Securities of that series or any Subsidiary Guarantee and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and each of the

The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.
Section 10.03.     Money for Securities Payments to be Held in Trust.
If the Company or any Subsidiary Guarantor shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.
Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, prior to 11:00 A.M., New York City time, on each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.
The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Company, the Subsidiary Guarantors, if applicable, or any other obligor upon the Securities of that series in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series.
The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.
Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The City of New York, New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

(b) The Company shall, so long as any series of Securities is Outstanding, deliver to the Trustee, as soon as possible and in any event within five days after the Company becomes aware of the occurrence of an Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’ Certificate setting forth the details of such Event of Default or default, and the action which the Company proposes to take with respect thereto.
Section 10.05.     Existence.
Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect the existence, rights (charter and statutory) and franchises of the Company; provided, however, that the Company shall not be required to preserve any such right or franchise if it shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders.
Section 10.06.     Maintenance of Properties.
The Company will cause all properties used or useful in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order (reasonable wear and tear excepted) and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any Subsidiary and not disadvantageous in any material respect to the Holders.
Section 10.07.     Payment of Taxes and Other Claims.
The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and (2) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings.
Section 10.08.     Maintenance of Insurance.
The Company shall, and shall cause its Subsidiaries to, keep at all times all of their properties which are of an insurable nature insured against loss or damage with insurers believed by the Company to be responsible to the extent that property of similar character is usually so insured by corporations similarly situated and owning like properties in accordance with good business practice.
Section 10.09.     Waiver of Certain Covenants.
    43

Exhibit 4.4
Except as otherwise specified as contemplated by Section 3.01 for Securities of such series, the Company and the Subsidiary Guarantors may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any of Sections 10.05 through 10.08 or in any covenant provided pursuant to Section 3.01(21), 9.01(2) or 9.01(5) or (7) for the benefit of the Holders of such series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.
ARTICLE ELEVEN
REDEMPTION OF SECURITIES
Section 11.01.     Applicability of Article.
Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 3.01 for such Securities) in accordance with this Article.
Section 11.02.     Election to Redeem; Notice to Trustee.
The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 3.01 for such Securities.
In case of any redemption at the election of the Company of less than all the Securities of any series (including any such redemption affecting only a single Security), the Company shall, at least five Business Days prior to giving notice of such redemption (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction.
Section 11.03.     Selection by Trustee of Securities to be Redeemed.
If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected by the Trustee, from the Outstanding Securities of such series not previously called for redemption, (i) in compliance with the requirements of the principal national securities exchange on which such Securities are listed, if such Securities are listed on any national securities exchange, and (ii) if such Securities are not so listed, on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of a portion of the principal amount of any Security of such series, provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with the preceding sentence.
The Trustee shall promptly notify the Company in writing of the Securities selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, the principal amount thereof to be redeemed.
    44

Exhibit 4.4
The provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security.
For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. If any Security selected for partial redemption is surrendered for conversion after such selection, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Upon any redemption of less than all the Securities of a series, for purposes of selection for redemption the Company and the Trustee may treat as Outstanding Securities surrendered for conversion during the period of 15 days next preceding the mailing of a notice of redemption, and need not treat as Outstanding any Security authenticated and delivered during such period in exchange for the unconverted portion of any Security converted in part during such period.
Section 11.04.     Notice of Redemption.
Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register; provided, however, notice of redemption may be given more than 60 days prior to the Redemption Date if the notice is issued in connection with a satisfaction and discharge pursuant to Article Four.
All notices of redemption shall state:
(1)     the Redemption Date,
(2)     the Redemption Price, if then determinable and otherwise the method of its determination,
(3)     if less than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed, the identification (and, in the case of partial redemption of any such Securities, the principal amounts) of the particular Securities to be redeemed and, if less than all the Outstanding Securities of any series consisting of a single Security are to be redeemed, the principal amount of the particular Security to be redeemed,
(4)     that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,
(5)     the place or places where each such Security is to be surrendered for payment of the Redemption Price,
(6)     that the redemption is for a sinking fund, if such is the case; and
(7)     if applicable, the conversion price then in effect and the date on which the right to convert such Securities will expire.
Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company and shall be irrevocable. If any Security called for redemption is converted pursuant hereto, any money deposited with the Trustee or any Paying Agent or so segregated and held in trust for the redemption of such Security shall be paid to the Company upon delivery of a Company Request to the Trustee or such Paying Agent, or, if then held by the Company, shall be discharged from such trust.
Section 11.05.     Deposit of Redemption Price.
Prior to 11:00 A.M., New York City time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as
    45

Exhibit 4.4
provided in Section 10.03) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date.
Section 11.06.     Securities Payable on Redemption Date.
Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 3.01, installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.07.
If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security.
Section 11.07.     Securities Redeemed in Part.
Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, if applicable, the Subsidiary Guarantors shall execute the notations of Subsidiary Guarantees endorsed thereon, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.
ARTICLE TWELVE
SUBORDINATION OF SECURITIES
Section 12.01.     Applicability of Article.

Section 12.02.     Securities Subordinate to Senior Debt.
The Company covenants and agrees, and each Holder of a Security, by his acceptance thereof, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article (subject to the provisions of Article Four and Article Fifteen), the payment of the principal of (and premium, if any) and interest on each and all of the Securities of such series is hereby expressly made subordinate and subject in right of payment to the prior payment in full of all Senior Debt of the Company.
No provisions of this Article Twelve shall prevent the occurrence of any Event of Default.
Section 12.03.     Payment Over of Proceeds Upon Dissolution, Etc.
    46

Exhibit 4.4
In the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the Company or to its creditors, as such, or to its assets, or (b) any liquidation, dissolution or other winding up of the Company, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or any other marshalling of assets and liabilities of the Company, then and in any such event specified in (a), (b) or (c) above (each such event, if any, herein sometimes referred to as a “Proceeding”) the holders of Senior Debt of the Company shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Debt of the Company, or provision shall be made for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Debt of the Company, before the Holders of the Securities are entitled to receive any payment or distribution of any kind or character, whether in cash, property or securities (including any payment or distribution which may be payable or deliverable by reason of the payment of any other indebtedness of the Company subordinated to the payment of the Securities, such payment or distribution being hereinafter referred to as a “Junior Subordinated Payment”), on account of principal of (or premium, if any) or interest on the Securities or on account of any purchase or other acquisition of Securities by the Company or any Subsidiary of the Company (all such payments, distributions, purchases and acquisitions, other than the payment or distribution of stock or securities of the Company referred to in the second succeeding paragraph, herein referred to, individually and collectively, as a “Securities Payment”), and to that end the holders of Senior Debt of the Company shall be entitled to receive, for application to the payment thereof, any Securities Payment which may be payable or deliverable in respect of the Securities in any such Proceeding.
In the event that, notwithstanding the foregoing provisions of this Section, the Trustee or the Holder of any Security shall have received any Securities Payment before all Senior Debt of the Company is paid in full or payment thereof provided for in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Debt of the Company, and if such fact shall, at or prior to the time of such Securities Payment, have been made known to the Trustee or, as the case may be, such Holder, then and in such event such Securities Payment shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other Person making payment or distribution of assets of the Company for application to the payment of all Senior Debt of the Company remaining unpaid, to the extent necessary to pay all Senior Debt of the Company in full, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt of the Company.
For purposes of this Article only, the words “any payment or distribution of any kind or character, whether in cash, property or securities” shall not be deemed to include a payment or distribution of stock or securities of the Company provided for by a plan of reorganization or readjustment authorized by an order or decree of a court of competent jurisdiction in a reorganization proceeding under any applicable bankruptcy law or of any other corporation provided for by such plan of reorganization or readjustment which stock or securities are subordinated in right of payment to all then outstanding Senior Debt of the Company to substantially the same extent as the Securities are so subordinated as provided in this Article. The consolidation of the Company with, or the merger of the Company into, another Person or the liquidation or dissolution of the Company following the conveyance or other disposition of all or substantially all of its assets to another Person upon the terms and conditions set forth in Article Eight shall not be deemed a Proceeding for the purposes of this Section if the Person formed by such consolidation or into which the Company is merged or the Person which acquires by conveyance or other disposition such assets, as the case may be, shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions set forth in Article Eight.
Section 12.04.     No Payment When Senior Debt of the Company in Default.
In the event that any Senior Payment Default (as defined below) shall have occurred and be continuing, then no Securities Payment shall be made unless and until such Senior Payment Default shall have been cured or waived or shall have ceased to exist or all amounts then due and payable in respect of Senior Debt of the Company shall have been paid in full, or provision shall have been made for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Debt of the Company; provided, however, that nothing in this Section shall prevent the satisfaction of any sinking fund payment in accordance with Article Sixteen by delivering and crediting pursuant to Section 16.02 Securities which have been acquired (upon redemption or otherwise) prior to such Senior Payment Default.
    47

Exhibit 4.4
“Senior Payment Default” means any default in the payment of principal of (or premium, if any) or interest on any Senior Debt of the Company when due, whether at the Stated Maturity of any such payment or by declaration of acceleration, call for redemption or otherwise.
In the event that any Senior Nonmonetary Default (as defined below) shall have occurred and be continuing, then, upon the receipt by the Company, the Subsidiary Guarantors and the Trustee of written notice of such Senior Nonmonetary Default from the agent for the Designated Senior Debt which is the subject of such Senior Nonmonetary Default, no Securities Payment shall be made during the period (the “Payment Blockage Period”) commencing on the date of such receipt of such written notice and ending on the earlier of (i) the date on which such Senior Nonmonetary Default shall have been cured or waived or shall have ceased to exist or all Designated Senior Debt the subject of such Senior Nonmonetary Default shall have been discharged; (ii) the 179th day after the date of such receipt of such written notice; or (iii) the date on which the Payment Blockage Period shall have been terminated by written notice to the Company, any Subsidiary Guarantor or the Trustee from the agent for the Designated Senior Debt initiating the Payment Blockage Period; provided, however, that nothing in this Section shall prevent the satisfaction of any sinking fund payment in accordance with Article Sixteen by delivering and crediting pursuant to Section 16.02 Securities which have been acquired (upon redemption or otherwise) prior to the date of such receipt of such written notice. No more than one Payment Blockage Period may be commenced with respect to the Securities of a particular series during any 360-day period and there shall be a period of at least 181 consecutive days in each 360-day period when no Payment Blockage Period is in effect. For all purposes of this paragraph, no Senior Nonmonetary Default that existed or was continuing on the date of commencement of any Payment Blockage Period shall be, or be made, the basis for the commencement of a subsequent Payment Blockage Period, whether or not within a period of 360 consecutive days, unless such Senior Nonmonetary Default shall have been cured for a period of not less than 90 consecutive days.
“Senior Nonmonetary Default” means the occurrence or existence and continuance of any event of default with respect to any Designated Senior Debt, other than a Senior Payment Default, permitting the holders of such Designated Senior Debt (or a trustee or agent on behalf of the holders thereof) to declare such Designated Senior Debt due and payable prior to the date on which it would otherwise become due and payable.
In the event that, notwithstanding the foregoing, the Company shall make any Securities Payment to the Trustee or any Holder prohibited by the foregoing provisions of this Section, and if such fact shall, at or prior to the time of such Securities Payment, have been made known to the Trustee or, as the case may be, such Holder, then and in such event such Securities Payment shall be paid over and delivered forthwith to the Company.
The provisions of this Section shall not apply to any Securities Payment with respect to which Section 12.03 would be applicable.
Section 12.05.     Payment Permitted If No Default.
Nothing contained in this Article or elsewhere in this Indenture or in any of the Securities shall prevent (a) the Company, at any time except during the pendency of any Proceeding referred to in Section 12.03 or under the conditions described in Section 12.04, from making Securities Payments, or (b) the application by the Trustee of any money deposited with it hereunder to Securities Payments or the retention of such Securities Payment by the Holders, if, at the time of such application by the Trustee, it did not have knowledge that such Securities Payment would have been prohibited by the provisions of this Article.
Section 12.06.     Subrogation to Rights of Holders of Senior Debt of the Company.
Subject to the payment in full of all amounts due or to become due on or in respect of Senior Debt of the Company, or the provision for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Debt of the Company, the Holders of the Securities shall be subrogated to the rights of the holders of such Senior Debt of the Company to receive payments and distributions of cash, property and securities applicable to the Senior Debt of the Company until the principal of (and premium, if any) and interest on the Securities shall be paid in full. For purposes of such subrogation, no payments or distributions to the holders of the Senior Debt of the Company of any cash, property or securities to which the Holders of the Securities or the Trustee

Exhibit 4.4
would be entitled except for the provisions of this Article, and no payments over pursuant to the provisions of this Article to the holders of Senior Debt of the Company by Holders of the Securities or the Trustee, shall, as among the Company, its creditors other than holders of Senior Debt of the Company and the Holders of the Securities, be deemed to be a payment or distribution by the Company to or on account of the Senior Debt of the Company.
Section 12.07.     Provisions Solely to Define Relative Rights.
The provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders on the one hand and the holders of Senior Debt of the Company on the other hand. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall (a) impair, as among the Company, its creditors other than holders of Senior Debt of the Company and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional (and which, subject to the rights under this Article of the holders of Senior Debt of the Company, is intended to rank equally with all other general obligations of the Company), to pay to the Holders of the Securities the principal of (and premium, if any) and interest on the Securities as and when the same shall become due and payable in accordance with their terms; or (b) affect the relative rights against the Company of the Holders of the Securities and creditors of the Company other than the holders of Senior Debt of the Company; or (c) prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior Debt of the Company to receive cash, property and securities otherwise payable or deliverable to the Trustee or such Holder.
Section 12.08.     Trustee to Effectuate Subordination.
Each Holder of a Security by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee his attorney-in-fact for any and all such purposes.
Section 12.09.     No Waiver of Subordination Provisions.
No right of any present or future holder of any Senior Debt of the Company to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with.
Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Debt of the Company may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Securities, without incurring responsibility to the Holders of the Securities and without impairing or releasing the subordination provided in this Article or the obligations hereunder of the Holders of the Securities to the holders of Senior Debt of the Company, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Debt of the Company, or otherwise amend or supplement in any manner Senior Debt of the Company or any instrument evidencing the same or any agreement under which Senior Debt of the Company is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Debt of the Company; (iii) release any Person liable in any manner for the collection of Senior Debt of the Company; and (iv) exercise or refrain from exercising any rights against the Company and any other Person.
Section 12.10.     Notice to Trustee.
The Company shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit the making of any payment to or by the Trustee in respect of the Securities. Notwithstanding the provisions of this Article or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect of the Securities, unless and until the Trustee shall have received written notice thereof from the Company or a holder of Senior Debt of the Company or from any trustee therefor; and, prior to the receipt of any such written notice, the
    49

Exhibit 4.4
Trustee, subject to the provisions of Section 6.01, shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received the notice provided for in this Section at least three Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without limitation, the payment of the principal of (and premium, if any) or interest on any Security), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it within three Business Days prior to such date.
Subject to the provisions of Section 6.01, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Debt of the Company (or a trustee therefor) to establish that such notice has been given by a holder of Senior Debt of the Company (or a trustee therefor). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Debt of the Company to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Debt of the Company held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article, and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment.
Section 12.11.     Reliance on Judicial Order or Certificate of Liquidating Agent.
Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee, subject to the provisions of Section 6.01, and the Holders of the Securities shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such Proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Debt of the Company and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article.
Section 12.12.     Trustee Not Fiduciary for Holders of Senior Debt of the Company.
The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt of the Company and shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company, a Subsidiary Guarantor or to any other Person cash, property or securities to which any holders of Senior Debt of the Company shall be entitled by virtue of this Article or otherwise.
Section 12.13.     Rights of Trustee as Holder of Senior Debt of the Company; Preservation of Trustee’s Rights.
The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article with respect to any Senior Debt of the Company which may at any time be held by it, to the same extent as any other holder of Senior Debt of the Company, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder.
Nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.07.
Section 12.14.     Article Applicable to Paying Agents.
In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee; provided, however, that Section 12.13 shall not apply to the Company, any Subsidiary Guarantor or any Affiliate of the Company if it or such Subsidiary Guarantor or Affiliate acts as Paying Agent.
    50

Exhibit 4.4
Section 12.15.     Defeasance of this Article Twelve.
The subordination of the Securities of a series provided by this Article Twelve is expressly made subject to the provisions for Defeasance or Covenant Defeasance in Article Fifteen hereof and, anything herein to the contrary notwithstanding, upon the effectiveness of any such Defeasance or Covenant Defeasance, the Securities of such series then outstanding shall thereupon cease to be subordinated pursuant to this Article Twelve.
ARTICLE THIRTEEN
SUBSIDIARY GUARANTEES
Section 13.01.     Applicability of Article.
Unless the Company elects to issue any series of Securities without the benefit of the Subsidiary Guarantees, which election shall be evidenced in or pursuant to the Board Resolution or supplemental indenture establishing such series of Securities pursuant to Section 3.01, the provisions of this Article shall be applicable to each series of Securities except as otherwise specified in or pursuant to the Board Resolution or supplemental indenture establishing such series pursuant to Section 3.01.
Section 13.02.     Subsidiary Guarantees.
Subject to Section 13.01, each Subsidiary Guarantor hereby, jointly and severally, fully and unconditionally guarantees to each Holder of a Security authenticated and delivered by the Trustee, the due and punctual payment of the principal of (and premium, if any) and interest on such Security when and as the same shall become due and payable, whether at the Stated Maturity, by acceleration, call for redemption, offer to purchase or otherwise, in accordance with the terms of such Security and of this Indenture, and each Subsidiary Guarantor similarly guarantees to the Trustee the payment of all amounts owing to the Trustee in accordance with the terms of this Indenture. In case of the failure of the Company punctually to make any such payment, each Subsidiary Guarantor hereby, jointly and severally, agrees to cause such payment to be made punctually when and as the same shall become due and payable, whether at the Stated Maturity or by acceleration, call for redemption, offer to purchase or otherwise, and as if such payment were made by the Company.
Each of the Subsidiary Guarantors hereby jointly and severally agrees that its obligations hereunder shall be absolute, unconditional, irrespective of, and shall be unaffected by, the validity, regularity or enforceability of such Security or this Indenture, the absence of any action to enforce the same or any release, amendment, waiver or indulgence granted to the Company or any other guarantor or any consent to departure from any requirement of any other guarantee of all or any of the Securities of such series or any other circumstances which might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor; provided, however, that, notwithstanding the foregoing, no such release, amendment, waiver or indulgence shall, without the consent of such Subsidiary Guarantor, increase the principal amount of such Security, or increase the interest rate thereon, or alter the Stated Maturity thereof. Each of the Subsidiary Guarantors hereby waives the benefits of diligence, presentment, demand for payment, any requirement that the Trustee or any of the Holders protect, secure, perfect or insure any security interest in or other lien on any property subject thereto or exhaust any right or take any action against the Company or any other Person or any collateral, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to such Security or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this Subsidiary Guarantee will not be discharged in respect of such Security except by complete performance of the obligations contained in such Security and in such Subsidiary Guarantee. Each Subsidiary Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Securities of a series, to collect interest on the Securities of a series, or to enforce or exercise any other right or remedy with respect to the Securities of a series, such Subsidiary Guarantor agrees to pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.
    51

Exhibit 4.4
The indebtedness of each Subsidiary Guarantor evidenced by the Subsidiary Guarantees is, to the extent provided in this Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Debt of each Subsidiary Guarantor, and the Subsidiary Guarantees are issued subject to the provisions of this Indenture with respect thereto. Each Holder of such Security, by accepting the same, will be deemed to have (a) agreed to and be bound by such provisions, (b) authorized and directed the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and (c) appointed the Trustee his attorney-in-fact for any and all such purposes.
Each Subsidiary Guarantor shall be subrogated to all rights of the Holders of the Securities upon which its Subsidiary Guarantee is endorsed against the Company in respect of any amounts paid by such Subsidiary Guarantor on account of such Security pursuant to the provisions of its Subsidiary Guarantee or this Indenture; provided, however, that no Subsidiary Guarantor shall be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until the principal of (and premium, if any) and interest on all Securities of the relevant series issued hereunder shall have been paid in full.
Each Subsidiary Guarantor that makes or is required to make any payment in respect of its Subsidiary Guarantee shall be entitled to seek contribution from the other Subsidiary Guarantors to the extent permitted by applicable law; provided, however, that no Subsidiary Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of contribution until the principal of (and premium, if any) and interest on all Securities of the relevant series issued hereunder shall have been paid in full.
Each Subsidiary Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Securities of a series, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any Holder of the Securities, whether as a “voidable preference,” “fraudulent transfer,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Securities shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.
Section 13.03.     Execution and Delivery of Notations of Subsidiary Guarantees.
To further evidence the Subsidiary Guarantee set forth in Section 13.02, each of the Subsidiary Guarantors hereby agrees that a notation relating to such Subsidiary Guarantee, substantially in the form set forth in Section 2.04, shall be endorsed on each Security entitled to the benefits of the Subsidiary Guarantee authenticated and delivered by the Trustee and executed by either manual or facsimile signature of an officer of such Subsidiary Guarantor, or in the case of a Subsidiary Guarantor that is a limited partnership, an officer of the general partner of each Subsidiary Guarantor. Each of the Subsidiary Guarantors hereby agrees that the Subsidiary Guarantee set forth in Section 13.02 shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation relating to the Subsidiary Guarantee. If any officer of the Subsidiary Guarantor, or in the case of a Subsidiary Guarantor that is a limited partnership, any officer of the general partner of the Subsidiary Guarantor, whose signature is on this Indenture or a Security no longer holds that office at the time the Trustee authenticates such Security or at any time thereafter, the Subsidiary Guarantee of such Security shall be valid nevertheless. The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantors.
Section 13.04.     Release of Subsidiary Guarantors.
Unless otherwise specified pursuant to Section 3.01 with respect to a series of Securities, each Subsidiary Guarantee will remain in effect with respect to the respective Subsidiary Guarantor until the entire principal of, premium, if any, and interest on the Securities to which such Subsidiary Guarantee relates shall have been paid in full or otherwise satisfied and discharged in accordance with the provisions of such Securities and this Indenture and all amounts owing to the Trustee hereunder have been paid; provided, however, that if (i) such Subsidiary Guarantor
    52

Exhibit 4.4
ceases to be a Subsidiary in compliance with the applicable provisions of this Indenture, (ii) either Defeasance or Covenant Defeasance occurs with respect to such Securities pursuant to Article Fifteen or (iii) all or substantially all of the assets of such Subsidiary Guarantor or all of the Capital Stock of such Subsidiary Guarantor is sold (including by sale, merger, consolidation or otherwise) by the Company or any Subsidiary in a transaction complying with the requirements of this Indenture, then, in each case of (i), (ii) or (iii), upon delivery by the Company of an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent herein provided for relating to the release of such Subsidiary Guarantor from its obligations under its Subsidiary Guarantee and this Article Thirteen have been complied with, such Subsidiary Guarantor shall be released and discharged of its obligations under its Subsidiary Guarantee and under this Article Thirteen without any action on the part of the Trustee or any Holder, and the Trustee shall execute any documents reasonably required in order to acknowledge the release of such Subsidiary Guarantor from its obligations under its Subsidiary Guarantee endorsed on the Securities of such series and under this Article Thirteen.
Section 13.05.     Additional Subsidiary Guarantors.
Unless otherwise specified pursuant to Section 3.01 with respect to a series of Securities, the Company will cause any domestic Wholly Owned Subsidiary of the Company that becomes a Subsidiary after the date the Securities of a series are first issued hereunder to become a Subsidiary Guarantor as soon as practicable after such Subsidiary becomes a Subsidiary. The Company shall cause any such Wholly Owned Subsidiary to become a Subsidiary Guarantor with respect to the Securities by executing and delivering to the Trustee (a) a supplemental indenture, in form and substance satisfactory to the Trustee, which subjects such Person to the provisions (including the representations and warranties) of this Indenture as a Subsidiary Guarantor and (b) an Opinion of Counsel to the effect that such supplemental indenture has been duly authorized and executed by such Person and such supplemental indenture and such Person’s obligations under its Subsidiary Guarantee and this Indenture constitute the legal, valid, binding and enforceable obligations of such Person (subject to such customary exceptions concerning creditors’ rights and equitable principles as may be acceptable to the Trustee in its discretion).
Section 13.06.        Limitation on Liability.
Any term or provision of this Indenture to the contrary notwithstanding, the maximum amount of the Subsidiary Guarantee of any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed by such Subsidiary Guarantor without rendering such Subsidiary Guarantee voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.
ARTICLE FOURTEEN
SUBORDINATION OF SUBSIDIARY GUARANTEES
Section 14.01.     Applicability of Article.
Unless otherwise provided with respect to the Securities of any series in or pursuant to the Board Resolution or supplemental indenture establishing such series of Securities pursuant to Section 3.01, the provisions of this Article shall be applicable to each series of Securities.
Section 14.02.     Subsidiary Guarantees Subordinate to Senior Debt of Subsidiary Guarantors.
Each Subsidiary Guarantor covenants and agrees, and each Holder of a Security, by his acceptance thereof, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article (subject to the provisions of Article Four and Article Fifteen), the Subsidiary Guarantee of such Subsidiary Guarantor is hereby expressly made subordinate and subject in right of payment to the prior payment in full of all Senior Debt of such Subsidiary Guarantor.
No provisions of this Article Fourteen shall prevent the occurrence of any Event of Default.
    53

Exhibit 4.4
Section 14.03.     Payment Over of Proceeds Upon Dissolution, Etc.
In the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to any Subsidiary Guarantor or to its creditors, as such, or to its assets, or (b) any liquidation, dissolution or other winding up of any Subsidiary Guarantor, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or any other marshalling of assets and liabilities of any Subsidiary Guarantor, then and in any such event specified in (a), (b) or (c) above (each such event, if any, herein sometimes referred to as a “Guarantor Proceeding”) the holders of Senior Debt of such Subsidiary Guarantor shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Debt of such Subsidiary Guarantor, or provision shall be made for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Debt of such Subsidiary Guarantor, before the Holders of the Securities are entitled to receive any payment or distribution of any kind or character, whether in cash, property or securities (including any payment or distribution which may be payable or deliverable by reason of the payment of any other indebtedness of such Subsidiary Guarantor subordinated to the payment of the Securities, such payment or distribution being hereinafter referred to as a “Guarantor Junior Subordinated Payment”), on account of the Subsidiary Guarantee of such Subsidiary Guarantor (all such payments, other than the payment or distribution of stock or securities of a Subsidiary Guarantor referred to in the second succeeding paragraph, herein referred to, individually and collectively, as a “Guarantee Payment”), and to that end the holders of Senior Debt of such Subsidiary Guarantor shall be entitled to receive, for application to the payment thereof, any Guarantee Payment which may be payable or deliverable in respect of such Subsidiary Guarantor’s Subsidiary Guarantee in any such Guarantor Proceeding.
In the event that, notwithstanding the foregoing provisions of this Section, the Trustee or the Holder of any Security shall have received any Guarantee Payment before all Senior Debt of such Subsidiary Guarantor is paid in full or payment thereof provided for in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Debt of such Subsidiary Guarantor, and if such fact shall, at or prior to the time of such Guarantee Payment, have been made known to the Trustee or, as the case may be, such Holder, then and in such event such Guarantee Payment shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other Person making payment or distribution of assets of such Subsidiary Guarantor for application to the payment of all Senior Debt of such Subsidiary Guarantor remaining unpaid, to the extent necessary to pay all Senior Debt of such Subsidiary Guarantor in full, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt of such Subsidiary Guarantor.
For purposes of this Article only, the words “any payment or distribution of any kind or character, whether in cash, property or securities” shall not be deemed to include a payment or distribution of stock or securities of a Subsidiary Guarantor provided for by a plan of reorganization or readjustment authorized by an order or decree of a court of competent jurisdiction in a reorganization proceeding under any applicable bankruptcy law or of any other corporation provided for by such plan of reorganization or readjustment which stock or securities are subordinated in right of payment to all then outstanding Senior Debt of such Subsidiary Guarantor to substantially the same extent as the Subsidiary Guarantees are so subordinated as provided in this Article. The consolidation of a Subsidiary Guarantor with, or the merger of a Subsidiary Guarantor into, another Person or the liquidation or dissolution of such Subsidiary Guarantor following the conveyance or other disposition of all or substantially all of its assets to another Person upon the terms and conditions set forth in Article Eight shall not be deemed a Guarantor Proceeding for the purposes of this Section if the Person formed by such consolidation or into which such Subsidiary Guarantor is merged or the Person which acquires by conveyance or transfer such assets, as the case may be, shall, as a part of such consolidation, merger, conveyance or other disposition, comply with the conditions set forth in Article Eight.
Section 14.04.     No Payment When Senior Debt of such Subsidiary Guarantor in Default.
In the event that any Senior Payment Default shall have occurred and be continuing, then no Guarantee Payment shall be made unless and until such Senior Payment Default shall have been cured or waived or shall have ceased to exist or all amounts then due and payable in respect of the relevant Senior Debt of the Company shall have been paid in full, or provision shall have been made for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of such Senior Debt; provided, that nothing in this Section shall prevent the
    54

Exhibit 4.4
satisfaction of any sinking fund payment in accordance with Article Sixteen by delivering and crediting pursuant to Section 16.02 Securities which have been acquired (upon redemption or otherwise) prior to such Senior Payment Default.
In the event that any Senior Nonmonetary Default shall have occurred and be continuing, then, upon the receipt by the Company, the Subsidiary Guarantors and the Trustee of written notice of such Senior Nonmonetary Default from any holder, or agent for the holders, of any Designated Senior Debt of the Company, no Guarantee Payment shall be made during the applicable Payment Blockage Period; provided, however, that nothing in this Section shall prevent the satisfaction of any sinking fund payment in accordance with Article Sixteen by delivering and crediting pursuant to Section 16.02 Securities which have been acquired (upon redemption or otherwise) prior to the date of such receipt of such written notice. No more than one Payment Blockage Period may be commenced with respect to the Subsidiary Guarantees during any 360-day period and there shall be a period of at least 181 consecutive days in each 360-day period when no Payment Blockage Period is in effect. For all purposes of this paragraph, no Senior Nonmonetary Default that existed or was continuing on the date of commencement of any Payment Blockage Period shall be, or be made, the basis for the commencement of a subsequent Payment Blockage Period, whether or not within a period of 360 consecutive days, unless such Senior Nonmonetary Default shall have been cured for a period of not less than 90 consecutive days.
In the event that, notwithstanding the foregoing, a Subsidiary Guarantor shall make any Guarantee Payment to the Trustee or any Holder prohibited by the foregoing provisions of this Section, and if such fact shall, at or prior to the time of such Guarantee Payment, have been made known to the Trustee or, as the case may be, such Holder, then and in such event such Guarantee Payment shall be paid over and delivered forthwith to the Company.
The provisions of this Section shall not apply to any Guarantee Payment with respect to which Section 14.03 would be applicable.
Section 14.05.     Payment Permitted If No Default.
Nothing contained in this Article or elsewhere in this Indenture or in any of the Subsidiary Guarantees shall prevent (a) a Subsidiary Guarantor, at any time except during the pendency of any Guarantor Proceeding referred to in Section 14.03 or under the conditions described in Section 14.04, from making Guarantee Payments, or (b) the application by the Trustee of any money deposited with it hereunder to Guarantee Payments or the retention of such Guarantee Payment by the Holders, if, at the time of such application by the Trustee, it did not have knowledge that such Guarantee Payment would have been prohibited by the provisions of this Article.
Section 14.06.     Subrogation to Rights of Holders of Senior Debt of such Subsidiary Guarantor.
Subject to the payment in full of all amounts due or to become due on or in respect of Senior Debt of a Subsidiary Guarantor, or the provision for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Debt of such Subsidiary Guarantor, the Holders of the Securities shall be subrogated to the rights of the holders of such Senior Debt of such Subsidiary Guarantor to receive payments and distributions of cash, property and securities applicable to the Senior Debt of such Subsidiary Guarantor until the principal of (and premium, if any) and interest on the Securities shall be paid in full. For purposes of such subrogation, no payments or distributions to the holders of the Senior Debt of a Subsidiary Guarantor of any cash, property or securities to which the Holders of the Securities or the Trustee would be entitled except for the provisions of this Article, and no payments over pursuant to the provisions of this Article to the holders of Senior Debt of a Subsidiary Guarantor by Holders of the Securities or the Trustee, shall, as among a Subsidiary Guarantor, its creditors other than holders of Senior Debt of such Subsidiary Guarantor and the Holders of the Securities, be deemed to be a payment or distribution by such Subsidiary Guarantor to or on account of the Senior Debt of such Subsidiary Guarantor.
Section 14.07.     Provisions Solely to Define Relative Rights.
The provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders on the one hand and the holders of Senior Debt of a Subsidiary Guarantor on the other hand. Nothing
    55

Exhibit 4.4
contained in this Article or elsewhere in this Indenture or in the Subsidiary Guarantees is intended to or shall (a) impair, as among a Subsidiary Guarantor, its creditors other than holders of Senior Debt of such Subsidiary Guarantor and the Holders of the Securities, the obligation of such Subsidiary Guarantor, which is absolute and unconditional (and which, subject to the rights under this Article of the holders of Senior Debt of such Subsidiary Guarantor, is intended to rank equally with all other general obligations of such Subsidiary Guarantor), to guarantee payment to the Holders of the Securities of the principal of (and premium, if any) and interest on the Securities as and when the same shall become due and payable in accordance with their terms; or (b) affect the relative rights against a Subsidiary Guarantor of the Holders of the Securities and creditors of such Subsidiary Guarantor other than the holders of Senior Debt of such Subsidiary Guarantor; or (c) prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior Debt of a Subsidiary Guarantor to receive cash, property and securities otherwise payable or deliverable to the Trustee or such Holder.
Section 14.08.     Trustee to Effectuate Subordination.
Each Holder of a Security by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee his attorney-in-fact for any and all such purposes.
Section 14.09.     No Waiver of Subordination Provisions.
No right of any present or future holder of any Senior Debt of a Subsidiary Guarantor to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of such Subsidiary Guarantor or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by such Subsidiary Guarantor with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with.
Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Debt of a Subsidiary Guarantor may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Securities, without incurring responsibility to the Holders of the Securities and without impairing or releasing the subordination provided in this Article or the obligations hereunder of the Holders of the Securities to the holders of Senior Debt of such Subsidiary Guarantor, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Debt of such Subsidiary Guarantor, or otherwise amend or supplement in any manner Senior Debt of such Subsidiary Guarantor or any instrument evidencing the same or any agreement under which Senior Debt of such Subsidiary Guarantor is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Debt of such Subsidiary Guarantor; (iii) release any Person liable in any manner for the collection of Senior Debt of such Subsidiary Guarantor; and (iv) exercise or refrain from exercising any rights against such Subsidiary Guarantor and any other Person.
Section 14.10.     Notice to Trustee.
Each Subsidiary Guarantor shall give prompt written notice to the Trustee of any fact known to such Subsidiary Guarantor which would prohibit the making of any payment to or by the Trustee in respect of its Subsidiary Guarantee. Notwithstanding the provisions of this Article or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect of the Subsidiary Guarantees, unless and until the Trustee shall have received written notice thereof from a Subsidiary Guarantor or a holder of Senior Debt of such Subsidiary Guarantor or from any trustee therefor; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Section 6.01, shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received the notice provided for in this Section at least three Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without limitation, the payment of the principal of (and premium, if any) or interest on any Security), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the
    56

Exhibit 4.4
same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it within three Business Days prior to such date.
Subject to the provisions of Section 6.01, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Debt of a Subsidiary Guarantor (or a trustee therefor) to establish that such notice has been given by a holder of Senior Debt of such Subsidiary Guarantor (or a trustee therefor). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Debt of a Subsidiary Guarantor to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Debt of such Subsidiary Guarantor held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article, and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment.
Section 14.11.     Reliance on Judicial Order or Certificate of Liquidating Agent.
Upon any payment or distribution of assets of a Subsidiary Guarantor referred to in this Article, the Trustee, subject to the provisions of Section 6.01, and the Holders of the Securities shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such Guarantor Proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Debt of such Subsidiary Guarantor and other indebtedness of such Subsidiary Guarantor, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article.
Section 14.12.     Trustee Not Fiduciary for Holders of Senior Debt of such Subsidiary Guarantor.
The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt of a Subsidiary Guarantor and shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company, a Subsidiary Guarantor, or to any other Person cash, property or securities to which any holders of Senior Debt of such Subsidiary Guarantor shall be entitled by virtue of this Article or otherwise.
Section 14.13.     Rights of Trustee as Holder of Senior Debt of such Subsidiary Guarantor; Preservation of Trustee’s Rights.
The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article with respect to any Senior Debt of a Subsidiary Guarantor which may at any time be held by it, to the same extent as any other holder of Senior Debt of such Subsidiary Guarantor, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder.
Nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.07.
Section 14.14.     Article Applicable to Paying Agents.
In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee; provided, however, that Section 14.13 shall not apply to the Company, any Subsidiary Guarantor or any Affiliate of the Company if it or such Subsidiary Guarantor or Affiliate acts as Paying Agent.

Exhibit 4.4
Section 14.15.     Defeasance of this Article Fourteen.
The subordination of the Subsidiary Guarantees provided by this Article Fourteen is expressly made subject to the provisions for Defeasance or Covenant Defeasance of a series of Securities in Article Fifteen hereof and, anything herein to the contrary notwithstanding, upon the effectiveness of any such Defeasance or Covenant Defeasance with respect to a series of Securities, the Subsidiary Guarantees of the Securities of such series shall thereupon cease to be subordinated pursuant to this Article Fourteen.
ARTICLE FIFTEEN
DEFEASANCE AND COVENANT DEFEASANCE
Section 15.01.     Company’s Option to Effect Defeasance or Covenant Defeasance.
The Company may elect, at its option at any time, to have Section 15.02 or Section 15.03 applied to any Securities or any series of Securities, as the case may be, designated pursuant to Section 3.01 as being defeasible pursuant to such Section 15.02 or 15.03, in accordance with any applicable requirements provided pursuant to Section 3.01 and upon compliance with the conditions set forth below in this Article. Any such election shall be evidenced in or pursuant to a Board Resolution or in another manner specified as contemplated by Section 3.01 for such Securities.
Section 15.02.     Defeasance and Discharge.
Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, the Company shall be deemed to have been discharged from its obligations, and each Subsidiary Guarantor shall be deemed to have been discharged from its obligations with respect to its Subsidiary Guarantee of such Securities, and the provisions of Articles Twelve and Fourteen shall cease to be effective, with respect to such Securities and Subsidiary Guarantees as provided in this Section on and after the date the conditions set forth in Section 15.04 are satisfied (herein called “Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of such Securities to receive, solely from the trust fund described in Section 15.04 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities when payments are due, or, if applicable, to convert such Securities in accordance with their terms, (2) the Company’s and each Subsidiary Guarantor’s obligations with respect to such Securities under Sections 3.04, 3.05, 3.06, 10.02 and 10.03, and, if applicable, their obligations with respect to the conversion of such Securities, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article.

Section 15.03.    Covenant Defeasance.
Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, (1) the Company shall be released from its obligations under Section 8.01(3), Sections 10.05 through 10.08, inclusive, and any covenants provided pursuant to Section 3.01(21), 9.01(2) or 9.01(7) for the benefit of the Holders of such Securities, and (2) the occurrence of any event specified in Sections 5.01(5) (with respect to any of Section 8.01(3), Sections 10.05 through 10.08, inclusive, and any such covenants provided pursuant to Section 3.01(21), 9.01(2) or 9.01(5) or (7)), 5.01(6), 5.01(7), 5.01(10) and 5.01(11) shall be deemed not to be or result in an Event of Default and (3) the provisions of Articles Twelve, Thirteen and Fourteen shall cease to be effective, in each case with respect to such Securities and Subsidiary Guarantees as provided in this Section on and after the date the conditions set forth in Section 15.04 are satisfied (herein called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to such Securities, the Company and the Subsidiary Guarantors, as applicable, may omit to comply with and shall have no liability in
    58

Exhibit 4.4
respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case of Section 5.01(5)) or Articles Twelve, Thirteen or Fourteen, whether directly or indirectly by reason of any reference elsewhere herein to any such Section or Article or by reason of any reference in any such Section or Article to any other provision herein or in any other document, but the remainder of this Indenture and such Securities shall be unaffected thereby.
Section 15.04.     Conditions to Defeasance or Covenant Defeasance.
The following shall be the conditions to the application of Section 15.02 or Section 15.03 to any Securities or any series of Securities, as the case may be:
(1)     The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee which satisfies the requirements contemplated by Section 6.09 and agrees to comply with the provisions of this Article applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefits of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, in each case sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge, the principal of and any premium and interest on such Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. As used herein, “U.S. Government Obligation” means (x) any security which is (i) a direct obligation of the United States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable at the option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S. Government Obligation which is specified in clause (x) above and held by such bank for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so specified and held, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal or interest evidenced by such depositary receipt.
(2)    In the event of an election to have Section 15.02 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this instrument, there has been a change in the applicable Federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Defeasance were not to occur.
(3)     In the event of an election to have Section 15.03 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur.
(4)     The Company shall have delivered to the Trustee an Officers’ Certificate to the effect that neither such Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit.
    59

Exhibit 4.4
(5)     No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to such Securities shall have occurred and be continuing at the time of such deposit (other than a default or an Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Debt) and the granting of liens to secure such borrowing) or, with regard to any such event specified in Sections 5.01(7) and (8), at any time on or prior to the 121st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 121st day).
(6)     Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act).
(7)     Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company or any Subsidiary is a party or by which it is bound.
(8)     At the time of such deposit, (A) no default in the payment of any principal of or premium or interest on any Senior Debt of the Company or any Subsidiary Guarantor shall have occurred and be continuing, (B) no event of default with respect to any Senior Debt of the Company or any Subsidiary Guarantor shall have resulted in such Senior Debt becoming, and continuing to be, due and payable prior to the date on which it would otherwise have become due and payable (unless payment of such Senior Debt has been made or duly provided for), and (C) no other event of default with respect to any Senior Debt of the Company or any Subsidiary Guarantor shall have occurred and be continuing permitting (after notice or lapse of time or both) the holders of such Senior Debt (or a trustee on behalf of such holders) to declare such Senior Debt due and payable prior to the date on which it would otherwise have become due and payable.
(9)     The Company shall have delivered to the Trustee an Opinion of Counsel to the effect that such deposit shall not cause either the Trustee or the trust so created to be subject to the Investment Company Act of 1940.
(10)     The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with.
Section 15.05.     Deposited Money and U.S. Government Obligations to be Held in Trust; Miscellaneous Provisions.
Subject to the provisions of the last paragraph of Section 10.03, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 15.06, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 15.04 in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other funds except to the extent required by law. Money and U.S. Government Obligations so held in trust shall not be subject to the provisions of Article Twelve or Article Fourteen.
The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 15.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of Outstanding Securities.
Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 15.04 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount
    60

Exhibit 4.4
thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities.
Section 15.06.     Reinstatement.
If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant to Section 15.02 or 15.03 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 15.05 with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust.
ARTICLE SIXTEEN

Re: Registration Statement on Form S-3

Ladies and Gentlemen:

This Opinion Letter is furnished to you in connection with your Registration Statement on Form S-3 (as amended or supplemented, the “Registration Statement”) filed on December 13, 2024 with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration by Natural Gas Services Group, Inc., a Colorado corporation (the “Company”) and its wholly owned subsidiary, NGSG Properties, LLC, a Colorado limited liability company (the “Subsidiary”) (collectively, the “Registrant”), of an indeterminate number of (i) shares of Common Stock, $0.01 par value per share of the Company (the “Common Stock”), (ii) shares of Preferred Stock, $0.01 par value per share of the Company (the “Preferred Stock”), (iii) senior and subordinated debt securities (the “Debt Securities”), (iv) guarantee (the “Guarantee”) of the Debt Securities by the Subsidiary (the “Guarantor”), (v) depositary shares of the Company representing a fractional interest in a share of Preferred Stock (the “Depositary Shares”), (vi) rights to purchase Common Stock, Preferred Stock, Debt Securities or Depositary Shares (the “Rights”), (vii) warrants to purchase Common Stock, Preferred Stock, Debt Securities or other securities (the “Warrants”), and (viii) units consisting of two or more of the foregoing securities (“Units”), having a maximum aggregate public offering price of $200,000,000.00. The Registration Statement provides that the Common Stock, Preferred Stock, Debt Securities, Guarantee, Depositary Shares, Rights, Warrants and Units may be sold from time to time in one or more offerings up to a total public offering price of $200,000,000.00 on terms and subject to limitations to be set forth in one or more prospectus supplements (each, a “Prospectus Supplement”) to the prospectus contained in the Registration Statement.

We have reviewed such documents and made such examination of law as we have deemed necessary or appropriate to give the opinions expressed below. We have relied, without independent verification, on certificates of public officials and, as to matters of fact material to the opinions set forth below, on certificates of officers of the Company.

This opinion letter is limited to matters governed by the Federal laws of the United States of America, the laws of the State of New York and the laws of the State of Colorado.

This Opinion Letter is limited to the matters stated herein, and no opinion is implied or may be inferred beyond the matters expressly stated.

For purposes of the opinions expressed in paragraphs (1) through (9) below, without limiting any other exceptions or qualifications set forth herein, we have assumed that after the issuance of the Common Stock offered pursuant to the Registration Statement, the total number of issued shares of Common Stock, together with the total number of shares of Common Stock reserved for issuance upon the exercise, exchange or conversion, as the case may be, of any exercisable, exchangeable or convertible security then outstanding, will not exceed the total number of authorized shares of Common Stock under the Company’s Articles of Incorporation, as amended and then in effect.

For purposes of the opinions expressed in paragraphs (1) through (9) below, without limiting any other exceptions or qualifications set forth herein, we have also assumed that after the issuance of the Preferred Stock offered pursuant to the Registration Statement, the total number of issued shares of Preferred Stock, together with the total number of shares of Preferred Stock reserved for issuance upon the exercise, exchange or conversion of any exercisable, exchangeable or convertible security then outstanding, will not exceed the total number of authorized shares of


Exhibit 5.1
Preferred Stock under the Company’s Articles of Incorporation, as amended and then in effect, and that the Company will not create a series of Preferred Stock that is assessable.

Based upon the foregoing and subject to the limitations, qualifications, exceptions and assumptions set forth herein, it is our opinion that:

1. When (i) specifically authorized for issuance by the Board of Directors of the Company or a duly authorized committee thereof (the “Common Stock Authorizing Resolution”) and (ii) shares of Common Stock have been issued as contemplated in the Common Stock Authorizing Resolution against receipt by the Company of the consideration therefor provided in the Common Stock Authorizing Resolution, such shares of Common Stock will be validly issued, fully paid and non-assessable.

2. When (i) specifically authorized for issuance by the Board of Directors of the Company or a duly authorized committee thereof (the “Preferred Stock Authorizing Resolution”) and (ii) shares of Preferred Stock have been issued as contemplated in the Preferred Stock Authorizing Resolution against receipt by the Company of the consideration therefor provided for in the Preferred Stock Authorizing Resolution, then (A) the Preferred Stock will be validly issued, fully paid and non-assessable and (B) if the Preferred Stock is convertible into Common Stock, the Common Stock, if and when duly issued upon the conversion of such Preferred Stock, will be validly issued, fully paid and non-assessable.

3. When (i) specifically authorized for issuance by the Board of Directors of the Company or a duly authorized committee thereof (the “Debt Securities Authorizing Resolution”); (ii) any required indenture relating either to senior Debt Securities or subordinated Debt Securities has been duly qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”); (iii) the trustee under the applicable indenture has been duly qualified under the Trust Indenture Act; (iv) the terms of the Debt Securities and of their issuance and sale have been duly established in conformity with the applicable indenture so as not to violate any law or result in any default under or breach of any agreement or instrument binding upon the Company and so as to comply with any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company; (v) any shares of Common Stock or Preferred Stock issuable upon conversion of the Debt Securities, if applicable, have been duly and validly authorized for issuance; (vi) the Debt Securities have been duly executed and authenticated in accordance with the applicable indenture; and (vii) the Debt Securities have been issued as contemplated in the Debt Securities Authorizing Resolution against receipt by the Company of the consideration therefor provided in the Debt Securities Authorizing Resolution, then (A) the Debt Securities will constitute valid and legally binding obligations of the Company and (B) if the Debt Securities are convertible into Common Stock or Preferred Stock, the Common Stock or Preferred Stock, if and when issued upon conversion of the Debt Securities will be validly issued, fully paid and non-assessable.

4. When (i) the terms of the Rights and the applicable rights agreement are established or authorized and the Rights are specifically authorized for issuance by the Board of Directors of the Company or a duly authorized committee thereof (the “Rights Authorizing Resolution”); (ii) the Rights are duly executed by the Company and all conditions for delivery of the Rights established in the Rights Authorizing Resolution have been met; and (iii) the Rights are delivered by the Company against receipt by the Company of the consideration, if any, therefor provided for in the Rights Authorizing Resolution, then such Rights will be binding obligations of the Company.

5. When (i) the terms of the Warrants and the applicable warrant agreement are established or authorized and the Warrants are specifically authorized for issuance by the Board of Directors of the Company or a duly authorized committee thereof (the “Warrants Authorizing Resolution”); (ii) the Warrants are duly executed by the Company and all conditions for delivery of the Warrants established in the Warrants Authorizing Resolution have been met; and (iii) the Warrants are delivered by the Company against receipt by the Company of the consideration therefor provided for in the Warrants Authorizing Resolution, then such Warrants will be binding obligations of the Company.

6. When: (i) the Board of Directors of the Company or a duly authorized committee thereof (the “Depositary Shares Authorizing Resolution”) has taken all necessary corporate action to approve the issuance and terms of the Depositary Shares, the terms of the offering thereof, and related matters, including the adoption of an amendment to the Articles of Incorporation (“Amendment”) relating to the designation of Preferred Stock


Exhibit 5.1
underlying such Depositary Shares and the filing of the Amendment with the Secretary of State of the State of Colorado; (ii) the deposit agreement (the “Deposit Agreement”) or agreements relating to the Depositary Shares and the related depositary receipts (the “Depositary Receipts”) have been duly authorized in the Depositary Shares Authorizing Resolution and validly executed and delivered by the Company and the depositary appointed by the Company; (iii) the shares of Preferred Stock underlying such Depositary Shares have been deposited with a bank or trust company (which meets the requirements for the depositary set forth in the Registration Statement) under the applicable Deposit Agreement; and (iv) the Depositary Receipts representing the Depositary Shares have been duly executed, countersigned, registered and delivered in accordance with the appropriate Deposit Agreement and the applicable definitive purchase, underwriting or similar agreement approved by the Board of Directors upon payment of the consideration therefor provided for therein, the Depositary Shares will be validly issued, fully paid and nonassessable.

7. When (i) the terms of the Units and the applicable terms of the securities included in the Units are established and the Units are specifically authorized for issuance by the Board of Directors of the Company or a duly authorized committee thereof (the “Units Authorizing Resolution”); (ii) the Units are duly executed by the Company and all conditions for delivery of the Units established in the Units Authorizing Resolution have been met; and (iii) the Units are delivered by the Company against receipt by the Company of the consideration therefor provided for in the Units Authorizing Resolution, then such Units will be binding obligations of the Company.

8. When (i) the indenture has been duly executed and delivered by the Company, Guarantor, and the trustee and (ii) the Guarantee has been executed and delivered by the Guarantor in accordance with the indenture and assuming the issuance has been authorized by the Board of Directors or governing body of the Guarantor, then the Guarantee will constitute a valid and binding obligation of the Guarantor enforceable against the Guarantor in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium and other laws affecting the enforceability of creditors’ rights generally and to court decisions with respect thereto and to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

9. The Company validly exists as a corporation under the laws of the State of Colorado. The Subsidiary validly exists as a limited liability company under the laws of the State of Colorado.

The opinions expressed in this Opinion Letter are subject to and qualified and limited by (i) applicable bankruptcy, insolvency, fraudulent transfer, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and (ii) general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance, injunctive relief or other equitable remedies regardless of whether enforceability is considered in a proceeding in equity or at law.

We hereby consent to the filing of this Opinion Letter as an exhibit to the Registration Statement and to the references to our firm under the caption “Legal Matters” in the prospectus forming a part of the Registration Statement. In giving our consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.
