PROSPECTUS

EXLSERVICE HOLDINGS, INC.

1,551,970 Shares of Common Stock

On August 27, 2021, ExlService Holdings, Inc. (“we,” “us,” “our” or the “Company”) entered into a Payoff and Termination Agreement (the “Payoff and Termination Agreement”) with Orogen Echo LLC (“Orogen” or the “selling securityholder”), an affiliate of The Orogen Group, pursuant to which we agreed to (i) a negotiated private exchange and prepayment of the Company’s $150,000,000 aggregate principal amount of 3.50% Convertible Senior Notes due October 1, 2024 (the “Notes”) and (ii) except as set forth in the Payoff and Termination Agreement, terminate the Investment Agreement, dated as of October 1, 2018, between the Company and Orogen related to the initial issuance of the Notes and other matters set forth therein. In accordance with the terms of the Payoff and Termination Agreement, we settled our outstanding obligations under the Notes by making a cash payment plus an issuance directly to Orogen of 1,551,970 shares of our common stock, par value $0.001 per share (“common stock”). Unless otherwise indicated, all information contained in this prospectus, including the number of our shares of common stock outstanding, gives effect to the 5-for-1 forward stock split effective August 1, 2023.

This prospectus relates to the resale by the selling securityholder from time to time, and in any manner described under “Plan of Distribution” in this prospectus, of up to an aggregate of 1,551,970 shares of our common stock. We are registering the sale of these shares on behalf of the selling securityholder, to be offered and sold by it from time to time, to satisfy certain registration rights that we have granted to the selling securityholder.

The selling securityholder may sell such shares of common stock in one or more transactions at fixed prices, at prevailing market prices at the time of sale, at prices related to such prevailing market prices, at varying prices determined at the time of sale or at privately negotiated prices directly to purchasers or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions. If the selling securityholder uses underwriters, broker-dealers or agents, we will name them and describe their compensation in a supplement to this prospectus as may be required. We will receive no proceeds from any sale by the selling securityholder of the securities offered by this prospectus, but in some cases we have agreed to pay certain registration expenses. Please read this prospectus and any applicable prospectus supplement carefully before you invest.

Our common stock is listed on the Nasdaq Global Select Market and trades under the symbol “EXLS”. On February 24, 2025, the closing sale price of our common stock on the Nasdaq Global Select Market was $48.21 per share.

Investing in our securities involves risks. You should carefully read and consider the risk factors included in this prospectus under the section entitled “Risk Factors” on page 4 of this prospectus, in any applicable prospectus supplement relating to a specific offering of securities, in our periodic reports filed with the Securities and Exchange Commission (the “SEC”) and in any other documents we file with the SEC.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements within the meaning of the United States Private Securities Litigation Reform Act of 1995. You should not place undue reliance on these statements because they are subject to numerous uncertainties and factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control. These statements often include words such as “may,” “will,” “should,” “believe,” “expect,” “anticipate,” “intend,” “plan,” “estimate” or similar expressions. These statements are based on assumptions that we have made in light of our experience in the industry as well as our perceptions of historical trends, current conditions, expected future developments and other factors we believe are appropriate under the circumstances. As you read and consider this prospectus, you should understand that these statements are not guarantees of performance or results. They involve known and unknown risks, uncertainties and assumptions. Although we believe that these forward-looking statements are based on reasonable assumptions, you should be aware that many factors could affect our actual financial results or results of operations and could cause actual results to differ materially from those in the forward-looking statements. These factors include but are not limited to:

iii

These and other factors are more fully discussed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. These and other risks could cause actual results to differ materially from those implied by forward-looking statements in this prospectus.

The forward-looking statements made by us in this prospectus, or elsewhere, speak only as of the date on which they were made. New risks and uncertainties may occur from time to time, and it is impossible for us to predict those events or how they may affect us. We have no obligation to update any forward-looking statements in this prospectus after the date of this prospectus, except as required by federal securities laws.

Orogen Transaction

On August 27, 2021, we entered into a Payoff and Termination Agreement (the “Payoff and Termination Agreement”) with Orogen Echo LLC (“Orogen” or the “selling securityholder”), an affiliate of The Orogen Group, pursuant to which we agreed to (i) a negotiated private exchange and prepayment of the Company’s $150,000,000 aggregate principal amount of 3.50% Convertible Senior Notes due October 1, 2024 (the “Notes”) and (ii) except as set forth in the Payoff and Termination Agreement, terminate the Investment Agreement, dated as of October 1, 2018, between the Company and Orogen (the “Investment Agreement”) related to the initial issuance of the Notes and other matters set forth therein.

In accordance with the terms of the Payoff and Termination Agreement, we settled our outstanding obligations under the Notes by making a cash payment to Orogen of $200 million, plus accrued and unpaid interest under the Notes through, and including, August 26, 2021, and by issuing directly to Orogen 1,551,970 shares of our common stock. In addition, subject to certain exceptions, Orogen agreed to a 90-day lock-up with respect to the transferability of shares of our common stock issued pursuant to the Payoff and Termination Agreement.

Forward Stock Split

On June 20, 2023, subsequent to the approval and recommendation of our board of directors, our stockholders approved an amendment to our amended and restated certificate of incorporation, which upon filing with the Secretary of State of the State of Delaware on August 1, 2023, and effectiveness thereof, effected a 5-for-1 forward stock split of our common stock and an increase in the number of authorized shares of our common stock from 100,000,000 shares to 400,000,000 shares. The par value of each share of common stock, $0.001, remained unchanged. All share and per share information in this prospectus has been adjusted to reflect the forward stock split.

Our common stock is currently listed on the Nasdaq Global Select Market under the symbol “EXLS.” We will not receive any of the proceeds of sales by the selling securityholder of any of the shares covered by this prospectus. When we refer to the “selling securityholder” in this prospectus, we are referring to the holder of the foregoing securities, and its transferees, pledgees or donees, or its respective successors-in-interest that may be identified in a supplement to this prospectus or, if required, a post-effective amendment to the registration statement of which this prospectus is a part.

See “Description of Capital Stock” below for a more detailed summary of the terms of our common stock.

RISK FACTORS

Investing in our securities involves risks. You should carefully consider the risk factors described below, as well as the risk factors in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, which are incorporated by reference into this prospectus, as the same may be amended, supplemented or superseded from time to time by our filings under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as well as any applicable prospectus supplement. Before making any investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus or in any applicable prospectus supplement. For more information, see the section entitled “Where You Can Find More Information” on page 19 of this prospectus. These risks could materially affect our business, results of operations or financial condition and affect the value of our securities. You could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business, results of operations or financial condition.

Risks Related to Our Common Stock

Our stock price continues to be volatile.

Our common stock has at times experienced substantial price volatility as a result of, among other reasons, variations between our actual and anticipated financial results, announcements by us and our competitors, terrorist attacks, natural disasters, epidemics or pandemics, or other such events impacting countries where we or our clients have operations, loss of one or more significant clients, announcements of technological developments, projections or speculation about our business or that of our competitors by the media or investment analysts or uncertainty about current global economic conditions. The stock market, as a whole, experiences extreme price and volume fluctuations that affect the market price of many companies, including technology companies, in ways that may have been unrelated to these companies’ operating performance. Furthermore, we believe our stock price should reflect future growth and profitability expectations and, if we fail to meet these expectations, this may have a materially adverse effect on the trading price of our common stock.

Delaware law and our fourth amended and restated certificate of incorporation and sixth amended and restated by-laws contain certain anti-takeover provisions that could delay or discourage business combinations and takeover attempts that stockholders may consider favorable.

Our fourth amended and restated certificate of incorporation and sixth amended and restated by-laws contain provisions that may make it more difficult, expensive or otherwise discourage a tender offer or a change in control or takeover attempt by a third-party that is opposed by our board of directors. These provisions include provisions permitting the board of directors to fill vacancies created by its expansion, provisions permitting the removal of directors only for cause and with the vote of holders of two thirds of our common stock, provisions requiring the vote of holders of two thirds of our common stock for certain amendments to our organizational documents, provisions barring stockholders from calling a special meeting of stockholders or requiring one to be called or from taking action by written consent and provisions that set forth advance notice procedures for stockholders’ nominations of directors and proposals for consideration at meetings of stockholders. These provisions may have the effect of delaying or preventing a change of control or changes in management that stockholders consider favorable. Additionally, because we are incorporated in Delaware, we are subject to Section 203 of the Delaware General Corporation Law. Section 203 may prohibit large stockholders, in particular those owning 15.0% or more of our outstanding voting stock, from merging or combining with us. These provisions of our fourth amended and restated certificate of incorporation, sixth amended and restated by-laws and Delaware law could discourage potential takeover attempts and reduce the price that investors might be willing to pay for shares of our common stock in the future which could reduce the market price of our stock.

We do not intend to pay dividends in the foreseeable future, and, because we are also a holding company, we may be unable to pay dividends.

For the foreseeable future, we intend to retain any earnings to finance the development and expansion of our business, and we do not anticipate paying any cash dividends on our common stock. Any future determination to pay dividends will be at the discretion of our board of directors and will be dependent on then-existing conditions, including our financial condition and results of operations, capital requirements, contractual restrictions, including restrictions under our credit agreement, business prospects and other factors that our board of directors considers relevant.

4

Furthermore, because we are also a holding company, any dividend payments would also depend on the cash flow from our subsidiaries. Accordingly, under certain circumstances, we may not be able to pay dividends even if our board of directors would otherwise deem it appropriate.

5

USE OF PROCEEDS

The selling securityholder will receive all of the proceeds from its sale from time to time of common stock under this prospectus and any accompanying prospectus supplement. We will not receive any proceeds from these sales.

6

SELLING SECURITYHOLDER

On August 27, 2021, we entered into the Payoff and Termination Agreement pursuant to which the shares of common stock to be sold under this prospectus relates. We have filed with the SEC under the Securities Act of 1933, as amended (the “Securities Act”), the registration statement of which this prospectus forms a part pursuant to the Investment Agreement. Pursuant to the Investment Agreement, we have agreed to use our reasonable efforts to keep the shelf registration statement of which this prospectus is a part effective until the earlier of such time as all registrable securities (a) have been sold in accordance with the plan of distribution disclosed in this prospectus and (b) otherwise cease to be deemed “Registrable Securities” (as defined in the Investment Agreement).

For purposes of this prospectus, “selling securityholder” includes Orogen and its permitted transferees, pledgees, assignees, distributees, donees or successors or others who later hold any of the selling securityholder’s interests. Our registration of the shares of our common stock does not necessarily mean that the selling securityholder will sell all or any of such common stock. Information about the selling securityholder may change over time. In particular, the selling securityholder identified below may have sold, transferred or otherwise disposed of all or a portion of its shares of common stock since the date on which it provided us with information regarding its ownership. Any changed or new information given to us by the selling securityholder will be set forth in supplements to this prospectus or amendments to the registration statement of which this prospectus is a part, if and when necessary.

Except as described above under “Risk Factors,” “Prospectus Summary—Orogen Transaction,” or in the footnotes in the beneficial ownership table below, the selling securityholder has not held any position or office, or has otherwise had a material relationship, with us or any of our subsidiaries within the past three years other than as a result of the ownership of our shares or other securities. Unless otherwise indicated below, to our knowledge, all persons named in the table have sole voting and investment power with respect to their shares of common stock, except to the extent authority is shared by their spouses under applicable law.

DESCRIPTION OF CAPITAL STOCK

General

The following descriptions of our capital stock and of certain provisions of our fourth amended and restated certificate of incorporation (“certificate of incorporation”) and sixth amended and restated by-laws (“by-laws”) and certain provisions of Delaware law do not purport to be complete and are subject to and qualified in their entirety by reference to the full text of our certificate of incorporation and our by-laws and the General Corporation Law of the State of Delaware (the “DGCL”). Our certificate of incorporation and by-laws are filed herewith and incorporated herein by reference. References in this section to the “Company,” “EXL,” “we,” “us” and “our” refer to ExlService Holdings, Inc. and not to any of its subsidiaries.

Our authorized capital stock consists of 400,000,000 shares of common stock and 15,000,000 of preferred stock. As of February 21, 2025, we had 162,304,673 shares of our common stock issued and outstanding. No shares of preferred stock are outstanding.

Common Stock

Voting Rights

The holders of our common stock are entitled to one vote per share on all matters submitted to a vote of stockholders, including the election of directors. Holders of the common stock do not have cumulative voting rights, which means that the holders of a majority of the shares of common stock cast in the election of a director in an uncontested election (as defined in our by-laws) can elect each director then being elected.

Preemptive Rights

Holders of the common stock do not have any preemptive rights under our certificate of incorporation or by-laws.

Dividends; Liquidation Rights

The holders of our common stock are entitled to receive dividends when, as, and if declared by our board out of legally available funds. Upon our liquidation or dissolution, the holders of common stock will be entitled to share ratably in those of our assets that are legally available for distribution to stockholders after payment of liabilities and subject to the prior rights of any holders of preferred stock then outstanding.

Other Rights

No conversion, redemption or sinking fund provisions apply to our common stock, and all of the outstanding shares of common stock are fully paid and nonassessable. The rights, preferences and privileges of holders of common stock are subject to the rights of the holders of shares of any series of preferred stock that may be issued in the future.

Preferred Stock

We are authorized, without shareholder approval, to issue up to 15,000,000 shares of preferred stock. Our board of directors is authorized, subject to limitations prescribed by Delaware law and our certificate of incorporation, to determine the terms and conditions of the preferred stock, including whether the shares of preferred stock will be issued in one or more series, the number of shares to be included in each series and the powers, designations, preferences and rights of the shares. Our board of directors also is authorized to designate any qualifications, limitations or restrictions on the shares without any further vote or action by the stockholders. The issuance of preferred stock may have the effect of delaying, deferring or preventing a change in control of our company and may adversely affect the voting and other rights of the holders of our common stock.

8

Certain Certificate of Incorporation, By-Law and Statutory Provisions

Certain of the provisions of our certificate of incorporation and by-laws and of the DGCL summarized below may have an anti-takeover effect and may delay, defer or prevent a tender offer or takeover attempt that a holder of shares of our common stock might consider in its interest, including an attempt that might result in a receipt of a premium over the market price for such shares.

Directors’ Liability; Indemnification of Directors and Officers

Our certificate of incorporation provides that a director or officer will not be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director or officer, except that under Section 102(b)(7) of the DGCL, this provision will not eliminate or limit liability:

This provision does not limit or eliminate our rights or those of any stockholder to seek non-monetary relief such as an injunction or rescission in the event of a breach of a director’s or officer’s duty of care. The provisions do not alter the liability of directors or officers under federal securities laws. In addition, our certificate of incorporation and by-laws provide that we indemnify each director and the officers, employees, and agents determined by our board of directors to the fullest extent provided by the laws of the State of Delaware.

Special Meetings of Stockholders

Our certificate of incorporation provides that special meetings of stockholders may be called only by the chairman or by a majority of the members of our board. Stockholders are not permitted to call a special meeting of stockholders, to require that the chairman call such a special meeting, or to require that our board request the calling of a special meeting of stockholders.

Stockholder Action; Advance Notice Requirements for Stockholder Proposals and Director Nominations

Our certificate of incorporation provides that stockholders may not take action by written consent, but may only take action at duly called annual or special meetings, unless the action to be effected by written consent and the taking of such action by written consent have expressly been approved in advance by the board. In addition, our by-laws establish advance notice procedures for:

Stockholders must notify our corporate secretary in writing prior to the meeting at which the matters are to be acted upon or directors are to be elected. The notice must contain the information specified in our by-laws. To be timely, the notice must be received at our corporate headquarters not less than 90 days nor more than 120 days prior to the first anniversary of the date of the prior year’s annual meeting of stockholders. If the annual meeting is advanced by more than 30 days, or delayed by more than 70 days, from the anniversary of the preceding year’s annual meeting, or if no annual meeting was held in the preceding year or for the first annual meeting following this offering, notice by the stockholder, to be timely, must be received not earlier than the 120^th day prior to the annual meeting and not later than the later of the 90^th day prior to the annual meeting or the 10th day following the day on which we notify stockholders of the date of the annual meeting, either by mail or other public disclosure. In the case of a special meeting of stockholders called to elect directors, the stockholder notice must be received not earlier than 120 days prior to the special meeting and not later than the later of the 90th day prior to the special meeting or 10th

9

day following the day on which we notify stockholders of the date of the special meeting, either by mail or other public disclosure. Notwithstanding the above, in the event that the number of directors to be elected to the board at an annual meeting is increased and we do not make any public announcement naming the nominees for the additional directorships at least 100 days before the first anniversary of the preceding year’s annual meeting, a stockholder notice of nomination shall also be considered timely, but only with respect to nominees for the additional directorships, if it is delivered not later than the close of business on the tenth day following the day on which such public announcement is first made. These provisions may preclude some stockholders from bringing matters before the stockholders at an annual or special meeting or from nominating candidates for director at an annual or special meeting.

Election and Removal of Directors

We do not have a classified board of directors. All of our directors are elected annually. The number of directors comprising our board of directors is fixed from time to time by the board of directors. Our certificate of incorporation and by-laws provide that our stockholders may remove directors with or without cause by the affirmative vote of the holders of at least a majority of the total voting power of our issued and outstanding capital stock entitled to vote in the election of directors. Our board of directors may elect a director to fill a vacancy, including vacancies created by the expansion of the board of directors. This system of electing and removing directors may discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for stockholders to replace a majority of our directors by limiting the methods available for removing directors.

Our certificate of incorporation and by-laws do not provide for cumulative voting in the election of directors.

Amendment of the Certificate of Incorporation and By-Laws

Our certificate of incorporation provides that the affirmative vote of the holders of at least 66²/₃% of the voting power of our issued and outstanding capital stock entitled to vote in the election of directors, is required to amend the following provisions of our certificate of incorporation:

In addition, the board of directors is permitted to alter our by-laws without obtaining stockholder approval and the affirmative vote of holders of at least 66²/₃% of the voting power of our issued and outstanding capital stock entitled to vote in the election of directors is required for any amendment to our by-laws by the stockholders.

Anti-Takeover Provisions of Delaware Law

We are subject to the provisions of Section 203 of the DGCL. In general, Section 203 prevents an interested stockholder (defined generally as a person owning 15% or more of the corporation’s outstanding capital stock entitled to vote generally in the election of directors) of a Delaware corporation from engaging in a business combination (as defined) for three years following the date that person became an interested stockholder unless various conditions are satisfied.

Exclusive Forum

Our by-laws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for any state law claim for (i) any derivative action or proceeding brought on our behalf; (ii) any action or proceeding asserting a claim of breach of a fiduciary duty owed by, or other wrongdoing by, any of our directors, officers, employees and agents to us or our

10

stockholders; (iii) any action or proceeding asserting a claim arising pursuant to any provision of the DGCL, our certificate of incorporation or our by-laws; (iv) any action or proceeding as to which the DGCL confers jurisdiction on the Court of Chancery; or (v) any action or proceeding asserting a claim that is governed by the internal affairs doctrine (the “Delaware Forum Provision”). In the event that the Court of Chancery does not have jurisdiction, the United States District Court for the District of Delaware shall be the sole and exclusive forum for each of the actions or proceedings described above. In the event that the United States District Court for the District of Delaware does not have jurisdiction, any competent state court of the State of Delaware shall be the sole and exclusive forum for each of the actions or proceedings described above. The Delaware Forum Provision will not apply to any causes of action arising under the Securities Act or the Exchange Act.

Further, our by-laws provide that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act (the “Federal Forum Provision”). In addition, our by-laws provide that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is deemed to have notice of and consented to the Delaware Forum Provision and the Federal Forum Provision; provided, however, that stockholders cannot and will not be deemed to have waived our compliance with the U.S. federal securities laws and the rules and regulations thereunder. The Delaware Forum Provision and the Federal Forum Provision may impose additional costs on stockholders, may limit our stockholders’ ability to bring a claim in a forum they find favorable, and the designated courts may reach different judgments or results than other courts. However, it is possible that a court could find our forum selection provisions to be inapplicable or unenforceable.

PLAN OF DISTRIBUTION

The selling securityholder, including its pledgees, donees, transferees, distributees, beneficiaries or other successors in interest, may from time to time offer some or all of the shares of common stock (the “Securities”) covered by this prospectus. To the extent required, this prospectus may be amended and supplemented from time to time to describe a specific plan of distribution designated by the selling securityholder.

The selling securityholder will not pay any of the costs, expenses and fees in connection with the registration and sale of the Securities covered by this prospectus, but it will pay any and all underwriting discounts, selling commissions and stock transfer taxes, if any, attributable to sales of the Securities. We will not receive any proceeds from the sale of the Securities covered hereby.

The selling securityholder may sell the Securities covered by this prospectus from time to time, and may also decide not to sell all or any of the Securities that it is allowed to sell under this prospectus. The selling securityholder will act independently of us in making decisions regarding the timing, manner and size of each sale. These dispositions may be at fixed prices, at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at varying prices determined at the time of sale, or at privately negotiated prices. Sales may be made by the selling securityholder in one or more types of transactions, which may include:

The selling securityholder may also resell all or a portion of its Securities in open market transactions in reliance upon Rule 144 under the Securities Act, provided the selling securityholder meets the criteria and conforms to the requirements of Rule 144 and all applicable laws and regulations.

The selling securityholder may enter into sale, forward sale and derivative transactions with third parties, or may sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with those sale, forward sale or derivative transactions, the third parties may sell securities covered by this prospectus, including in short sale transactions and by issuing securities that are not covered by this prospectus but are exchangeable for or represent beneficial interests in the common stock. The third parties also may use shares received under those sale, forward sale or derivative arrangements or shares pledged by the selling securityholder or

12

borrowed from the selling securityholder or others to settle such third-party sales or to close out any related open borrowings of common stock. The third parties may deliver this prospectus in connection with any such transactions. Any third party in such sale transactions will be an underwriter and will be identified in a supplement or a post-effective amendment to the registration statement of which this prospectus is a part as may be required.

In addition, the selling securityholder may engage in hedging transactions with broker-dealers in connection with distributions of Securities or otherwise. In those transactions, broker-dealers may engage in short sales of securities in the course of hedging the positions they assume with the selling securityholder. The selling securityholder may also sell securities short and redeliver securities to close out such short positions. The selling securityholder may also enter into option or other transactions with broker-dealers which require the delivery of securities to the broker-dealer. The broker-dealer may then resell or otherwise transfer such securities pursuant to this prospectus. The selling securityholder also may loan or pledge shares, and the borrower or pledgee may sell or otherwise transfer the Securities so loaned or pledged pursuant to this prospectus. Such borrower or pledgee also may transfer those Securities to investors in our securities or the selling securityholder’s securities or in connection with the offering of other securities not covered by this prospectus.

To the extent necessary, the specific terms of the offering of Securities, the name of the selling securityholder, the respective purchase prices and public offering prices, the names of any underwriter, broker-dealer or agent, if any, and any applicable compensation in the form of discounts, concessions or commissions paid to underwriters or agents or paid or allowed to dealers will be set forth in a supplement to this prospectus or a post-effective amendment to this registration statement of which this prospectus forms a part. The selling securityholder may, or may authorize underwriters, dealers and agents to, solicit offers from specified institutions to purchase Securities from the selling securityholder. These sales may be made under “delayed delivery contracts” or other purchase contracts that provide for payment and delivery on a specified future date. If necessary, any such contracts will be described and be subject to the conditions set forth in a supplement to this prospectus or a post-effective amendment to this registration statement of which this prospectus forms a part.

Broker-dealers or agents may receive compensation in the form of commissions, discounts or concessions from the selling securityholder. Broker-dealers or agents may also receive compensation from the purchasers of Securities for whom they act as agents or to whom they sell as principals, or both. Compensation as to a particular broker-dealer might be in excess of customary commissions and will be in amounts to be negotiated in connection with transactions involving Securities. In effecting sales, broker-dealers engaged by the selling securityholder may arrange for other broker-dealers to participate in the resales.

In connection with sales of Securities covered hereby, the selling securityholder and any underwriter, broker-dealer or agent and any other participating broker-dealer that executes sales for the selling securityholder may be deemed to be an “underwriter” within the meaning of the Securities Act. Accordingly, any profits realized by the selling securityholder and any compensation earned by such underwriter, broker-dealer or agent may be deemed to be underwriting discounts and commissions. If the selling securityholder is an “underwriter” under the Securities Act, it must deliver this prospectus in the manner required by the Securities Act. This prospectus delivery requirement may be satisfied through the facilities of the NASDAQ Stock Market in accordance with Rule 153 under the Securities Act or satisfied in accordance with Rule 174 under the Securities Act.

In connection with an offering of Securities under this prospectus, the underwriters may purchase and sell securities of the Company in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of securities than they are required to purchase in an offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the securities while an offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased securities sold by or for the account of that underwriter in stabilizing or short-covering transactions.

13

These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the Securities offered under this prospectus. As a result, the price of the Securities may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected on the NASDAQ Stock Market or another securities exchange or automated quotation system, or in the over-the-counter market or otherwise.

We and the selling securityholder have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act. In addition, we or the selling securityholder may agree to indemnify any underwriters, broker-dealers and agents against or contribute to any payments the underwriters, broker-dealers or agents may be required to make with respect to, civil liabilities, including liabilities under the Securities Act. Underwriters, broker-dealers and agents and their affiliates are permitted to be customers of, engage in transactions with, or perform services for us and our affiliates or the selling securityholder or its affiliates in the ordinary course of business.

The selling securityholder will be subject to applicable provisions of Regulation M of the Exchange Act and the rules and regulations thereunder, which provisions may limit the timing of purchases and sales of any of the Securities by the selling securityholder. Regulation M may also restrict the ability of any person engaged in the distribution of the Securities to engage in market-making activities with respect to the Securities. These restrictions may affect the marketability of such Securities.

In order to comply with applicable securities laws of some states or countries, the Securities may only be sold in those jurisdictions through registered or licensed brokers or dealers and in compliance with applicable laws and regulations. In addition, in certain states or countries the Securities may not be sold unless they have been registered or qualified for sale in the applicable state or country or an exemption from the registration or qualification requirements is available. In addition, any Securities of a selling securityholder covered by this prospectus that qualify for sale pursuant to Rule 144 under the Securities Act may be sold in open market transactions under Rule 144 rather than pursuant to this prospectus.

CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a general summary of certain material U.S. federal income tax consequences of the purchase, ownership and disposition of shares of our common stock by Non-U.S. Holders (as defined below), as of the date of this prospectus. This summary does not purport to be a comprehensive description of all the potential tax considerations that may be relevant to a holder’s decision to purchase our common stock, including any tax consequences that arise from rules of general application to all taxpayers or certain classes of taxpayers. This summary is based upon the provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations (including proposed Treasury regulations) promulgated thereunder, administrative rulings and judicial decisions, each as of the date hereof. These authorities may be changed, or subject to differing interpretations, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those set forth below. We have not sought any ruling from the U.S. Internal Revenue Service (the “IRS”) with respect to the matters discussed below, and there can be no assurance that the IRS or a court will not take a contrary position regarding the tax consequences of the purchase, ownership or disposition of our common stock.

This summary assumes that our common stock will be held as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all aspects of U.S. federal income taxes that may be relevant to Non-U.S. Holders in light of their particular circumstances, does not deal with state or local taxes, U.S. federal gift and estate tax laws or any non-U.S. tax consequences. In addition, this discussion does not address all tax considerations that may be applicable to a Non-U.S. Holder’s particular circumstances or to holders that may be subject to special tax rules, including, without limitation:

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our common stock, the U.S. federal income tax treatment of a partner in the partnership generally will depend on the activities of the partnership and the status of the partner. Prospective investors that are partners in partnerships (or entities or arrangements treated as partnerships for U.S. federal income tax purposes) should consult their tax advisors regarding the U.S. federal income tax consequences to them of the purchase, ownership and disposition of our common stock.

THIS SUMMARY OF CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. YOU SHOULD CONSULT YOUR TAX ADVISOR WITH RESPECT TO THE APPLICATION OF U.S. FEDERAL INCOME TAX LAWS TO YOUR PARTICULAR SITUATION AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER U.S. FEDERAL ESTATE OR GIFT TAX RULES OR UNDER THE LAWS OF ANY STATE, LOCAL, NON-U.S. OR ANY OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

15

As used herein, the term “U.S. holder” means a beneficial owner of our common stock that is, for U.S. federal income tax purposes:

For purposes of this discussion, a “Non-U.S. Holder” is a beneficial owner of our common stock that is neither a U.S. Holder nor a partnership for U.S. federal income tax purposes.

Distributions

Distributions of cash or property, if any, made on our common stock to a Non-U.S. Holder of our common stock generally will constitute dividends for U.S. federal income tax purposes to the extent made out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles) and will be subject to withholding tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and such Non-U.S. Holder’s country of residence. A Non-U.S. Holder who claims the benefit of an applicable income tax treaty between the United States and such holder’s country of residence generally will be required to provide a properly executed IRS Form W-8BEN or W-8BEN-E (or successor form) and satisfy applicable certification and other requirements. Special certifications and requirements may apply to a Non-U.S. Holder that is an intermediary or that owns stock through an intermediary. A Non-U.S. Holder that is eligible for a reduced rate of U.S. withholding tax under an income tax treaty may generally obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim with the IRS. Non-U.S. Holders are urged to consult their tax advisors regarding their entitlement to benefits under a relevant income tax treaty.

Dividends that are treated as effectively connected with a trade or business conducted by a Non-U.S. Holder within the United States and, if an applicable income tax treaty so provides, that are attributable to a permanent establishment or a fixed base maintained by the Non-U.S. Holder within the United States are generally exempt from the 30% withholding tax if the Non-U.S. Holder satisfies applicable certification and disclosure requirements. However, such U.S. effectively connected income is taxed on a net income basis at the same U.S. federal income tax rates applicable to United States persons (as defined in the Code). Any U.S. effectively connected income received by a Non-U.S. Holder that is a corporation may also, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and such Non-U.S. Holder’s country of residence.

If the amount of a distribution exceeds our current and accumulated earnings and profits, such excess will be allocated ratably among each share of our common stock and will be treated as a tax-free return of capital to the extent of a Non-U.S. Holder’s adjusted tax basis in such share of our common stock, and thereafter will be treated as capital gain. See “—Gain on Sale or Other Taxable Disposition” below.

Gain on Sale or Other Taxable Disposition

Subject to the discussion below under “—Information Reporting and Backup Withholding,” a Non-U.S. Holder generally will not be subject to U.S. federal income tax on gain recognized on a sale or other taxable disposition of our common stock unless:

16

Information Reporting and Backup Withholding

Generally, distributions in respect of our common stock to a Non-U.S. Holder, and the amount of any tax withheld from such payments must be reported annually to the IRS and to the Non-U.S. Holder. Copies of these information returns may be made available by the IRS to the tax authorities of the country in which the Non-U.S. Holder is a resident under the provisions of an applicable income tax treaty. Under certain circumstances, backup withholding of U.S. federal income tax may apply to distributions in respect of our common stock to a Non-U.S. Holder if the Non-U.S. Holder fails to certify under penalties of perjury that it is not a United States person.

Payments of the proceeds of the sale or other disposition of our common stock to or through a foreign office of a U.S. broker or of a foreign broker with certain specified U.S. connections will be subject to information reporting requirements, unless (i) the broker has evidence in its records that the payee is not a United States person, and the broker has no actual knowledge or reason to know to the contrary, or (ii) the payee otherwise establishes an exemption; and generally will not be subject to backup withholding. Payments of the proceeds of a sale or other disposition of our common stock to or through the U.S. office of a broker will be subject to information reporting and backup withholding unless the payee certifies under penalties of perjury that it is not a United States person (and the payor has no actual knowledge or reason to know to the contrary) or otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules generally will be allowed as a refund or credit against a Non-U.S. Holder’s U.S. federal income tax liability (if any); provided that the required information is timely furnished to the IRS. Non-U.S. Holders should consult their tax advisors about the filing of a U.S. federal income tax return in order to obtain a refund.

Foreign Accounts

The Foreign Account Tax Compliance Act (“FATCA”) imposes withholding at a 30% rate on certain types of “withholdable payments” (including interest paid on debt instruments and dividends paid on stock in a U.S. corporation) made to a “foreign financial institution” or to a “non-financial foreign entity” (all as defined in the Code) (whether such foreign financial institution or non-financial foreign entity is the beneficial owner or an intermediary), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain U.S. persons or U.S.-owned foreign entities (as defined in applicable

17

Treasury Regulations), annually report certain information about such accounts and withhold 30% on payments to noncompliant foreign financial institutions and certain other account holders. Foreign entities that hold our common stock generally will be subject to this tax unless they certify on an applicable IRS Form W-8 (generally, IRS Form W-8BEN-E) that they comply with, or are deemed to comply with, or are exempted from the application of, these rules.

Various requirements and exceptions are provided under FATCA and additional requirements and exceptions may be provided in subsequent guidance. Further, the United States has entered into many intergovernmental agreements (“IGAs”) with foreign governments relating to the implementation of, and information sharing under, FATCA, and such IGAs may alter one or more of the FATCA information reporting rules. Non-U.S. Holders should consult their tax advisors regarding the potential application and impact of these requirements based on their particular circumstances. Particularly, Non-U.S. Holders should consult their tax advisors regarding the possible implications of FATCA on their investment in our common stock and the entities through which they hold our common stock.

THE PRECEDING DISCUSSION OF MATERIAL U.S. FEDERAL TAX CONSIDERATIONS IS FOR PROSPECTIVE INVESTORS’ INFORMATION ONLY. IT IS NOT TAX ADVICE. PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE PARTICULAR U.S. FEDERAL, STATE, LOCAL, AND NON-U.S. TAX CONSEQUENCES OF THE PURCHASING, OWNING AND DISPOSING OF OUR COMMON STOCK, INCLUDING THE CONSEQUENCES OF ANY PROPOSED CHANGES IN APPLICABLE LAWS.

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 14. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION.

The following is an estimate, subject to future contingencies of the expenses to be incurred by the Registrant in connection with the sale and distribution of the securities being registered:

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Section 145(a) of the DGCL provides, in general, that a corporation has the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with the action, suit or proceeding, if such person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.

Section 145(b) of the DGCL provides, in general, that a corporation has the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor because the person is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of any other enterprise, against any expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

The Company’s fourth amended and restated certificate of incorporation and sixth amended and restated by-laws provide that the Company shall indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, which the Company refers to as a proceeding, by reason of the fact that he or she, or a person for whom he or she is the legal representative, is or was a director or officer of the Company or, while a director or officer of the Company, is or was serving at the request of the Company as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or nonprofit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including attorneys’ fees) reasonably incurred by such person; provided, however, that the Company shall be required to indemnify a person in connection with a proceeding (or part thereof) initiated by such person only if the commencement of such proceeding (or part thereof) was authorized by the board of directors.

II-1

Section 102 of the DGCL permits, and the Company’s fourth amended and restated certificate of incorporation provides for, the limitation of directors’ or officers’ personal liability to the corporation or its stockholders for monetary damages for breach of fiduciary duties as a director or officer, except for (i) any breach of the director’s or officer’s duty of loyalty to the corporation or its stockholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, (iii) breaches under section 174 of the DGCL, which relates to unlawful payments of dividends or unlawful stock repurchase or redemptions, (iv) any transaction from which the director or officer derived an improper personal benefit, and (v) with respect to officers, in any action by or in the right of the Company (i.e., derivative actions).

The Company is required to advance expenses, as incurred, to its directors and officers in connection with defending a proceeding, except that such director or officer shall undertake to repay such advances if it is ultimately determined that such person is not entitled to indemnification.

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

The Company maintains directors’ and officers’ liability insurance for its officers and directors.

ITEM 16. EXHIBITS

The Exhibits listed on the Exhibit Index of this Registration Statement are filed herewith or are incorporated herein by reference to other filings.

EXHIBIT INDEX

ITEM 17. UNDERTAKINGS.

The undersigned registrants hereby undertakes:

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

II-2

(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 the 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 paragraphs (i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act 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 part of the registration statement.

(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 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.

(i) Any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

II-3

(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;

(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.

That, for purposes of determining any liability under the Securities Act, 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.

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

Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to ExlService Holdings, Inc., a Delaware corporation (the “Company”), in connection with the Company’s registration statement on Form S-3 (the “Registration Statement”), including the prospectus that is part of the Registration Statement (the “Prospectus”), filed on the date hereof, with the U.S. Securities and Exchange Commission (the “Commission”), under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement relates to the registration of the resale by the selling stockholder named in the Prospectus (the “Selling Stockholder”) of up to 1,551,970 shares (the “Shares”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”). The Shares are described in the Registration Statement and may be sold from time to time by the Selling Stockholder.

This opinion letter is being furnished in accordance with the requirements of Item 16 of Form S-3 and Item 601(b)(5)(i) of Regulation S-K promulgated under the Securities Act. Capitalized terms used and not defined herein shall have the meanings assigned to them in the Registration Statement.

In connection with this opinion, we have reviewed the corporate proceedings taken by the Company with respect to the issue and sale, and registration of the resale of, the Shares. We have also examined and relied upon originals or copies of such corporate records, documents, agreements or other instruments of the Company, and such certificates and records of public officials, and such other documents, as we have deemed necessary or appropriate in connection herewith, including, but not limited to, the Company’s Fourth Amended and Restated Certificate of Incorporation and the Company’s Sixth Amended and Restated By-laws. As to all matters of fact (including, without limitation, factual conclusions and characterizations and descriptions of purpose, intention or other state of mind) we have relied entirely upon a certificate of an officer of the Company, and have assumed, without independent inquiry, the accuracy of that certificate.

In rendering this opinion, we have assumed the genuineness and authenticity of all signatures on the original documents; the legal capacity of all natural persons; the authenticity of all documents submitted to us as originals; the conformity to originals of all documents submitted to us as certified or photocopies; the accuracy and completeness of all documents and records reviewed by us; the accuracy, completeness and authenticity of certificates issued by any governmental

official, office or agency and the absence of change in the information contained therein from the effective date of any such certificate; and the due authorization, execution and delivery of all documents where authorization, execution and delivery are prerequisites to the effectiveness of such documents, except that we make no such assumption with respect to the Company.

Our opinion is expressed only with respect to the General Corporation Law of the State of Delaware. We are not opining as to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or, in the case of Delaware, any other laws, or as to matters of municipal law or the laws of any local agencies within any states (including “blue sky” or other state securities laws).

Based upon the foregoing, we are of the opinion that the Shares were validly issued, fully paid and non-assessable.

We assume no obligation to supplement this opinion if any applicable law changes after the date hereof or if we become aware of any fact that might change the opinion expressed herein after the date hereof.

We hereby consent to the filing of this opinion as a part of the Registration Statement and to the reference of our firm under the caption “Legal Matters” in the Prospectus. In giving such consent, we do not hereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission. Except as otherwise set forth herein, this opinion may not be used, circulated, quoted or otherwise referred to for any purpose or relied upon by any other person without the express written permission of this firm.
