PRELIMINARY PROXY STATEMENT, SUBJECT TO COMPLETION, DATED FEBRUARY 24, 2022

Dear Shareholder:

You are cordially invited to attend a special meeting of the shareholders (the “Special Meeting”) of Armata Pharmaceuticals, Inc., a Washington corporation (“Armata,” the “Company,” “we,” “our” or “us”). The Special Meeting will be held on March 30, 2022 at 9:00 am local time at our principal executive offices at 4503 Glencoe Avenue, Marina del Rey, California 90292, unless postponed or adjourned to a later date.

On February 9, 2022, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Innoviva Strategic Opportunities LLC (“Innoviva LLC”), a wholly-owned subsidiary of Innoviva, Inc. (Nasdaq: INVA) (collectively, “Innoviva”), pursuant to which the Company agreed to issue and sell to Innoviva LLC, in a private placement (the “Private Placement”), up to 9,000,000 newly issued shares (the “Shares”) of our common stock, par value $0.01 (the “Common Stock”), and warrants (the “Warrants”) to purchase up to 4,500,000 shares of Common Stock, with an exercise price per share of $5.00. The Purchase Agreement provides for the sale of the Shares and Warrants to Innoviva LLC in units, each consisting of one Share and one Warrant, for a per unit price of $5.00. Each Warrant is convertible into one-half Share of Common Stock.

The Private Placement is expected to occur in two tranches. The closing of the first tranche (the “First Closing”, and the issuance of Shares in the First Closing, the “First Placement”) occurred on February 9, 2022. In connection with the First Closing, Armata issued 3,614,792 shares of Common Stock and Warrants to purchase up to 1,807,396 shares of Common Stock (which was the maximum number of Shares and Warrants issuable to Innoviva LLC in compliance with any and all applicable laws and without the requirement for the prior receipt of the shareholders’ approval under the listing requirements of the NYSE American) in exchange for net proceeds of approximately $18.1 million.

At the closing of the second tranche (the “Second Closing”, and the issuance of Shares in the Second Closing, the “Second Placement”), subject to satisfaction of certain closing conditions, including the Company’s shareholders voting in favor of the transaction at this Special Meeting, Innoviva LLC will purchase approximately 5,385,208 shares of Common Stock and Warrants to purchase up to 2,692,604 shares of Common Stock for an aggregate purchase price of approximately $26.9 million.

At the First Closing, Innoviva and the Company entered into an amended and restated investor rights agreement (the “A&R IRA”), which amended and restated the existing investor rights agreement entered into by the Company and Innoviva, Inc. on February 12, 2020, as amended and restated on January 26, 2021 (the “Prior IRA”). The A&R IRA did not substantively modify or amend the Prior IRA and provides that, for so long as Innoviva and its affiliates hold at least 12.5% of the outstanding shares of Common Stock on a fully-diluted basis, Innoviva and its affiliates shall have the right to designate two directors to the Board of Directors of the Company (the “Board”), and, for so long as Innoviva and its affiliates hold at least 8% but less than 12.5% of the outstanding shares of Common Stock on a fully-diluted basis, Innoviva and its affiliates shall have the right to designate one director to the Board, subject to certain qualifications and conditions in the A&R IRA. The A&R IRA also provides for participation rights for Innoviva and its affiliates to participate in future offerings of equity securities by the Company.

Following the First Closing, the Company may be considered a “controlled company” under the rules of the NYSE American. As a controlled company, our Board would no longer be required by the NYSE American to be composed of a majority of independent directors, and our Compensation Committee and Nominating and Corporate Governance Committee would no longer be required by the NYSE American to be composed solely of independent directors. At present, we do not intend to take advantage of any of the foregoing exceptions to the NYSE American corporate governance requirements. Under the rules of the

NYSE American and the SEC, our Audit Committee must continue to be composed solely of independent directors, regardless of whether or not Armata is a controlled company.

As part of the First Closing, the Company also entered into a registration rights agreement (the “Registration Rights Agreement”) with Innoviva LLC. Pursuant to the Registration Rights Agreement, the Company must file a registration statement on Form S-1 or Form S-3 (the “Shelf Registration Statement”) covering the resale of the securities issued and sold pursuant to the Purchase Agreement with the U.S. Securities and Exchange Commission (the “Commission”) on a continuous basis pursuant to Rule 415 promulgated under the Securities Act of 1933, as amended (the “Securities Act”), or if Rule 415 is not available for offers and sales of such securities, by such other means of distribution of such securities as Innoviva may reasonably specify.

The Company also entered into an amended and restated Voting Agreement with Innoviva and Innoviva LLC (the “Voting Agreement”), which amended and restated in its entirety that certain Voting Agreement dated January 26, 2021, as amended and restated as of October 28, 2021 (the “Prior Voting Agreement”) concurrently with the First Closing, pursuant to which Innoviva and Innoviva LLC agreed not to vote or take any action by written consent with respect to any shares of common stock of the Company held by Innoviva or any of its subsidiaries which represent, in the aggregate, in excess of 49.5% of the total number of shares of common stock voting with respect to certain matters (such shares, the “Excess Shares”) related to the election or removal of directors or amendment of the bylaws of the Company to reduce the maximum number of directors or set the number of directors who may serve on the Board (“Board Matters”) presented at any meeting of the shareholders of the Company (or any adjournment or postponement thereof), or for their action by written consent, in each case, unless the Board authorizes Innoviva or its affiliates to vote such Excess Shares with respect to Board Matters.

The Second Closing is expected to occur by the end of the first quarter of 2022, subject to the satisfaction of certain closing conditions referenced above. Following the Second Closing, Innoviva and its affiliates will remain our largest shareholder, owning approximately 69.4% of the outstanding Common Stock of the Company, assuming no exercise of the Warrants, and if Innoviva and its affiliates exercise all of the Warrants, it will own approximately 77.6% of the outstanding Common Stock of the Company.

In connection with the transactions described above, the Company is holding the Special Meeting for the following purposes, as more fully described in the accompanying proxy statement:

To approve the closing of the Second Placement, which, combined with the First Placement, will result in the issuance of shares equal to 20% or more of the outstanding common stock of the Company for less than the greater of book or market value of the Company’s Common Stock, as required by and in accordance with NYSE American Company Guide Rule 713 (the “Private Placement Proposal”);

To authorize the adjournment of the Special Meeting in order to permit the solicitation of additional proxies if there are not sufficient votes to approve Proposal 1 described above at the time of the Special Meeting; and

To conduct any other business properly brought before the Special Meeting or any adjournment or postponement thereof.

Innoviva will remain the majority shareholder of the Company after the closing of the Second Placement. The Company’s Common Stock will continue to be listed on the NYSE American, and the Company will continue as a public reporting company under the rules of the Commission.

After careful consideration, the Board, acting upon the unanimous approval and recommendation of the qualified independent director committee of the Board comprised of Todd C. Peterson, Joseph M. Patti, and Robin C. Kramer and the recommendation of the audit committee of the Board, in addition to reliance upon a fairness opinion issued by the Board’s financial advisory firm, Ladenburg Thalmann & Co. Inc, opining that the transaction is fair, from a financial point of view, to the stockholders of the Company, determined that the Purchase Agreement and the transactions contemplated thereby, including the Private Placement, are expedient and in the best interests of the Company and its shareholders, and has determined to recommend that the Company’s shareholders vote to approve each of the proposals set

forth in this proxy statement. Accordingly, the Board unanimously recommends that you vote FOR Proposal 1 described above and FOR Proposal 2 for the authorization to adjourn the Special Meeting in order to permit the solicitation of additional proxies if there are not sufficient votes to approve Proposal 1 at the time of the Special Meeting.

The Proxy Statement attached to this letter provides you with more specific information concerning the Special Meeting, the Purchase Agreement, the transactions contemplated by the Purchase Agreement, including the Private Placement, and other related matters, including information as to how to cast your vote. The Company encourages you to read the entire proxy statement, the copy of the Purchase Agreement attached as Annex A to the proxy statement, and the other annexes to the proxy statement carefully and in their entirely.

Your vote is important, regardless of the number of shares of Common Stock that you own. Under the rules of the NYSE American, the affirmative vote of the majority of votes cast at a meeting where a quorum is present is required for the approval of Proposal 1. Under our Bylaws, the affirmative vote of the majority of votes represented at a meeting, whether in person or by proxy, is required for approval of Proposal 2.

We intend to hold the Special Meeting in person. However, we are sensitive to the public health and travel concerns our shareholders may have and recommendations that public health officials may issue due to the evolving COVID-19 coronavirus situation. Your contributions are valued by the Company, however, shareholders are strongly encouraged to vote their shares by proxy as the preferred means of fully and safely exercising their rights. Personal attendance at the meeting may present a health risk to shareholders and others. In addition, we request that individuals (1) who have been in contact with someone diagnosed with COVID-19 within two weeks prior to the Special Meeting, or (2) who are experiencing a fever, cough, difficulty breathing, or cold- or flu-like symptoms, refrain from attending the Special Meeting in person.

In light of the COVID-19 pandemic, it could become necessary to change the date, time, location, and/or means of holding the Special Meeting (including by means of remote communication). If such a change is made, we will announce the change in advance, and details on how to participate will be issued by press release, posted on our website, and filed with the Commission as additional proxy materials.

Whether or not you plan to attend the Special Meeting in person, please vote your proxy as soon as possible to assure a quorum. Under our Bylaws, a majority of the votes entitled to be cast on a matter by the holders of shares that are entitled to vote and be counted collectively upon such matter, represented in person or by proxy, constitutes a quorum. You may vote by attending the Special Meeting in person, by submitting a proxy over the internet or by telephone, or by mailing the enclosed proxy card pursuant to the instructions provided in the accompanying proxy statement. If your shares of Common Stock are held in “street name” by your broker, bank, or other nominee, then in order to vote, you will need to instruct your broker, bank, or other nominee on how to vote your shares by using the instructions provided by your broker, bank, or other nominee. The proposals for consideration at the Special Meeting are considered “non-routine” matters, and, therefore, no broker has discretion to vote on any of the proposals to be considered at the meeting without voting instructions from the beneficial owner of the shares. A shareholder’s shares will not be counted as present for the purpose of determining the existence of a quorum if no instructions have been provided on how to vote on any of the proposals.

Only those shareholders who own shares of Common Stock at the close of business on March , 2022, the record date for the Special Meeting, will be entitled to vote at the Special Meeting or any adjournment or postponement thereof.

(“Armata,” the “Company,” “we,” “our” or “us”) to be held on March 30, 2022 at 9:00 am local time at our principal executive offices at 4503 Glencoe Avenue, Marina del Rey, California 90292, and at any adjournments or postponements thereof. This proxy statement, along with the accompanying Notice of Special Meeting of Shareholders, summarizes the information you need to know to vote by proxy or in person at the Special Meeting. We anticipate that on or about , 2022, we will begin mailing this proxy statement, along with a Notice of Special Meeting of Shareholders and a form of proxy, to all shareholders entitled to vote at the Special Meeting. The following are answers to certain questions that you may have regarding the Special Meeting. We urge you to read carefully the remainder of this proxy statement because the information in this section may not provide all the information that you may consider important in determining how to vote.

QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND THE SPECIAL MEETING

Why am I receiving this Proxy Statement?

The Board of Directors (the “Board” or “Board of Directors”) is inviting you to vote at the Special Meeting, including any adjournments or postponements of the Special Meeting, because you were a shareholder of record at the close of business on March , 2022 and are entitled to vote at the Special Meeting on the proposals specified below.

This proxy statement summarizes the information you need to know to vote at the Special Meeting. You are invited to attend the Special Meeting in person to vote on the proposals described in this proxy statement. However, you do not need to attend the Special Meeting to vote your shares. Instead, you may follow the instructions below to submit your proxy to vote your shares.

What am I voting on?

•

Proposal 1: To approve the closing of the Second Placement, which, combined with the First Placement, will result in the issuance of shares equal to 20% or more of the outstanding common stock of the Company for less than the greater of book or market value of the Company’s Common Stock, as required by and in accordance with NYSE American Company Guide Rule 713 (the “Private Placement Proposal”); and

•

Proposal 2: To authorize the adjournment of the Special Meeting in order to permit the solicitation of additional proxies if there are not sufficient votes to approve Proposal 1 described above at the time of the Special Meeting.

When is the Second Placement expected to be completed?

The Second Placement is expected to be completed by the end of the first quarter of 2022.

What are the primary terms of the Private Placement to Innoviva LLC?

In the Private Placement, we are issuing and selling, and Innoviva LLC is purchasing 9,000,000 newly issued Shares and Warrants to purchase up to 4,500,000 shares of Common Stock, with an exercise price

per share of $5.00. The Shares and Warrants are being issued and sold to Innoviva LLC as units, each consisting of one Share and one Warrant, for a per unit price of $5.00. Each Warrant is convertible into one-half share of Common Stock.

At the closing of the second tranche (the “Second Closing”, and the issuance of Shares in the Second Closing, the “Second Placement”), subject to satisfaction of certain closing conditions, including the Company’s shareholders voting in favor of the transaction at this Special Meeting, Innoviva LLC will purchase approximately 5,385,208 shares of Common Stock and Warrants to purchase approximately 2,692,604 shares of Common Stock for an aggregate purchase price of approximately $26.93 million.

If shareholders approve the Private Placement, will I be required to sell my Common Stock?

The Private Placement involves the purchase by Innoviva LLC of newly issued shares of Common Stock. It is not a purchase of shares from our existing shareholders or a merger, pursuant to which our shareholders would receive consideration in exchange for their Common Stock. You will not be required to sell your Common Stock.

If the Private Placement is approved, will we remain a public company?

Whether or not the Private Placement is approved, we will continue to remain a public company, with our shares listed for trading on the NYSE American and the requirement to file our annual reports (including the audited financial statements contained therein) and other reports with the U.S. Securities and Exchange Commission (the “SEC”).

What is the effect to us and our other shareholders of having Innoviva as our largest shareholder?

Except as set forth in the A&R IRA (as defined below) and the Voting Agreement (as defined below), all shares of Common Stock of the Company, regardless of who owns them, have the same rights and privileges. See “Proposal 1 — Purchase Agreement and Private Placement.”

Because of Innoviva’s significant ownership of us, any transaction or arrangement between us, on the one hand, and Innoviva or any of its affiliates, on the other hand, will need to be approved by the Board consistent with its fiduciary duties to all of our shareholders. This will entail full disclosure to the Board, as well as separate approval by the Audit Committee of the Board, which is composed solely of the independent directors. In addition, relationships, transactions or other arrangements between us and Innoviva and/or its affiliates must be disclosed by us in our filings with the SEC.

Following the Second Closing, Innoviva will remain our largest shareholder, owning approximately 69.4% of the outstanding common stock of the Company, assuming no exercise of the Warrants, and if Innoviva exercises all of the Warrants, it will own approximately 77.6% of the outstanding common stock of the Company.

Does the Board recommend shareholder approval of the Private Placement?

After careful consideration, the Board, acting upon the unanimous approval by and recommendation of the independent qualified director committee of the Board comprised of Todd C. Peterson, Joseph M. Patti, and Robin C. Kramer and the recommendation of the audit committee of the Board, in addition to reliance upon a fairness opinion issued by the Board’s independent financial advisory firm Ladenburg Thalmann & Co. Inc., opining that the transaction is fair, from a financial point of view, to the stockholders of the Company, determined that the Purchase Agreement and the transactions contemplated thereby, including the Private Placement, are expedient and in the best interests of the Company and our shareholders.

Accordingly, the Board recommends that our shareholders vote:

•

“FOR” Proposal 1: approval of Private Placement Proposal; and

•

“FOR” Proposal 2: to authorize the adjournment of the Special Meeting in order to permit the solicitation of additional proxies if there are not sufficient votes to approve Proposal 1 described above at the time of the Special Meeting.

What factors did the Board consider and what were its reasons for approving the Purchase Agreement and recommending that the shareholders approve the Private Placement?

The Board formed a special committee of independent directors to evaluate and approve an equity financing transaction of up to approximately $45.0 million. After careful consideration, the Board, acting upon the unanimous approval by and recommendation of the qualified independent director committee of the Board and the recommendation of the audit committee of the Board, in addition to reliance upon a fairness opinion issued by Ladenburg Thalmann & Co. Inc., determined that the Purchase Agreement and the transactions contemplated thereby, including the Private Placement, are expedient and in the best interests of the Company and our shareholders, and determined to recommend that our shareholders approve the Private Placement.

In making its determinations, the Board considered various factors, including:

•

The value Innoviva has provided as a principal shareholder in supporting Armata with its ongoing advancement of its bacteriophage development programs, including its FDA cleared first-in-human study, SWARM-P.a., which is evaluating the Company’s lead phage product candidate, AP-PA02, as a potential treatment for Pseudomonas aeruginosa airway infections in cystic fibrosis patients, and the expected clinical trial related to AP-SA02, a phage targeting Staphylococcus aureus, in patients with complicated bacteremia later this year.

•

The recent performance of the Company’s stock price on the NYSE American.

•

The immediate and long-term benefit to Armata’s financial condition of receiving approximately $45 million in cash from the sale of the Shares and Warrants, in light of the Company’s current cash position and longer-term liquidity needs.

•

The Company management’s analysis of alternative sources of capital, including public or private sales of common stock, warrants, or convertible or nonconvertible debt securities and the likely price and other terms and conditions of such sales, which revealed significant cost of such financing, assuming it could be obtained, to the Company and the associated significant dilution to its shareholders, which the Board determined was substantially less favorable to the Company than pursuing this transaction.

•

The number of shares of our Common Stock beneficially owned by Innoviva prior to the First Closing, which was approximately 59.3% of our outstanding shares assuming no exercise of warrants held by Innoviva, and approximately 70.7% of our issued and outstanding shares of common stock assuming full exercise of the warrants held by Innoviva.

•

That the shareholders approved the private placement transaction with Innoviva and the change in control of Armata in March 2020, making Innoviva the largest shareholder of the Company and entitling Innoviva to designate two directors to serve on the Board.

•

In consideration of the terms of a similarly structured private placement transaction with Innoviva and one other unrelated third-party investor which was concluded in October 2021.

•

Reliance upon the fairness opinion issued by Ladenburg & Thalmann Co. Inc., the Board’s financial advisor.

•

Armata’s prior exploration of opportunities for strategic partnership and/or investment, based on which the Board believes that the Private Placement offers the best opportunity with greatest financial benefit and likelihood of successful development of its clinical programs, including the risks that any such anticipated benefits could ultimately not materialize.

•

The terms and conditions of the Purchase Agreement, including, among other things, the representations, warranties, covenants and agreements of the parties, the conditions to closing, the form and governance of the Company post-closing and the termination rights of the parties, taken as a whole, which the Board determined were more favorable to the Company and its shareholders than those terms and conditions which could have been negotiated with or offered by other potential strategic partners and/or investors.

•

Restrictions under the Purchase Agreement on the Company’s ability to operate its business in the ordinary course until the consummation of the Second Closing.

•

Potential risks associated with alternatives to the Private Placement, including the potential impact on the price of Armata’s common stock and ability to generate sufficient capital to support the ongoing advancement of its bacteriophage development programs.

How do I attend the Special Meeting?

The Special Meeting will be held on March 30, 2022 at 9:00 am local time at our principal executive offices at 4503 Glencoe Avenue, Marina del Rey, California 90292. Information on how to vote in person at the Special Meeting is discussed below.

Who can vote at the Special Meeting?

Only shareholders of record at the close of business on March , 2022 will be entitled to vote at the Special Meeting. On this record date, there were shares of Common Stock outstanding and entitled to vote.

Shareholder of Record: Shares Registered in Your Name

If on the record date your shares were registered directly in your name with our transfer agent, Computershare, Inc., then you are a shareholder of record.

Whether or not you plan to attend the Special Meeting, we urge you to vote your shares over the internet, by telephone, or by mail by filling out and returning the enclosed proxy card in the postage-paid envelope provided.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank

If on the record date your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and our proxy materials are being forwarded to you by that organization. The broker, bank, or other agent holding your account is considered to be the shareholder of record for purposes of voting at the Special Meeting. As a beneficial owner, you have the right to direct your broker, bank, or other agent regarding how to vote the shares in your account. You are also invited to attend the Special Meeting. However, since you are not the shareholder of record, you may not vote your shares in person at the Special Meeting unless you request and obtain a valid proxy from your broker, bank, or other agent.

How do I vote?

For each of the proposals at the Special Meeting, you may vote “For” the proposal, “Against” the proposal, or abstain from voting.

The procedures for voting are fairly simple:

Shareholder of Record: Shares Registered in Your Name

Whether or not you plan to attend the Special Meeting, we urge you to vote by proxy to ensure your vote is counted.

•

•

To vote through the internet, go to [www. ] to complete an electronic proxy card. You will be asked to provide the control number from the enclosed proxy card. Your vote must be received by 11:59 p.m. Eastern Time on , , 2022 to be counted.

•

To vote over the telephone, dial toll-free [( ) - ] using a touch-tone phone and follow the recorded instructions. You will be asked to provide the control number from the enclosed proxy card. Your vote must be received by 11:59 p.m. Eastern Time on , , 2022 to be counted.

Your proxy (one of the individuals named in your proxy card) will vote your shares per your instructions. If you are a shareholder of record, your shares will not be voted if you do not vote by internet or telephone, return your proxy card by mail, or vote in person at the Special Meeting as described above; however, if you properly submit a proxy, but do not specify your voting choice on one or more of the proposals included thereon, your shares will be voted, as recommended by the Board, acting upon the unanimous approval by and recommendation of the qualified independent director committee of the Board comprised of Todd C. Peterson, Joseph M. Patti, and Robin C. Kramer, the recommendation of the audit committee of the Board and reliance upon the fairness opinion issued by Ladenburg & Thalmann Co. Inc.: (1) to approve the Private Placement; and (2) to authorize the adjournment of the Special Meeting in order to permit the solicitation of additional proxies if there are not sufficient votes to approve Proposal 1 at the time of the Special Meeting.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you have shares held by a broker, bank, or other agent, you may instruct such agent to vote your shares by following the instructions that such broker, bank, or other agent provides to you. Most brokers and nominees allow you to vote by mail, telephone, and on the internet. As discussed further below, under New York Stock Exchange rules, the approval of the Private Placement Proposal (Proposal 1) is considered “non-routine,” meaning that brokers, banks, or other agents who have not been furnished voting instructions from their clients will not be authorized to vote in their discretion on these proposals. The adjournment proposal (Proposal 2) is considered a “routine” matter, meaning that brokers, banks, or other agents who have not been furnished voting instructions from their clients will be authorized to vote on that proposal.

To vote in person at the Special Meeting, you must obtain a valid proxy form from your broker, bank, or other agent. Follow the provided instructions from your broker or bank, or contact your broker or bank to request a proxy form.

We provide internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your internet access, such as usage charges from internet access providers and telephone companies.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of Common Stock you owned as of the close of business on the record date.

What happens if I do not vote?

Shareholder of Record: Shares Registered in Your Name

If you are a shareholder of record and do not vote through the internet, by completing your proxy card, by telephone, or in person at the Special Meeting, your shares will not be voted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner and do not instruct your broker, bank, or other agent how to vote your shares, the question of whether such agent will still be able to vote your shares depends on whether the New York Stock Exchange deems the particular proposal to be a “routine” matter. Brokers, banks, and other agents can use their discretion to vote “uninstructed” shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the rules and interpretations of the New York Stock Exchange, “non-routine” matters are matters that may substantially affect the rights or privileges of shareholders, such as mergers, shareholder proposals, elections of directors (even if not contested), and certain corporate governance proposals, even if management-supported. For these “non-routine” matters for which a broker, bank or other agent has not received voting instructions, a “broker non-vote” occurs. Accordingly, your broker, bank or other agent may not vote your shares on Proposal 1 without your instructions (resulting in “broker non-votes” for such matters), but may vote your shares on Proposal 2 even in the absence of your instruction.

What if I return a proxy card or otherwise vote but do not make specific choices?

If you return a signed and dated proxy card or otherwise vote without marking your voting selections, your shares will be voted, as applicable: “For” Proposal 1, the approval of the Private Placement Proposal; and “For” Proposal 2, the authorization of the adjournment of the Special Meeting in order to permit the solicitation of additional proxies if there are not sufficient votes to approve Proposal 1 at the time of the Special Meeting.

Do shareholders have any dissenters’ right with regards to the matters proposed to be acted upon?

There are no rights of appraisal or other similar rights of dissenters under the laws of the State of Washington with respect to any of the matters proposed to be acted upon herein.

Are any of the Company shareholders already committed to vote in favor of the proposals?

We anticipate that Innoviva will vote the shares held by it in favor of Proposal 1 and Proposal 2.

What happens if I sell my shares of Common Stock before the Special Meeting?

The record date for shareholders entitled to vote at the Special Meeting is earlier than the date of the Special Meeting. If you transfer your shares of common stock after the record date but before the Special Meeting, you will, unless special arrangements are made to confer the voting rights with respect to such shares to the transferee, retain your right to vote at the Special Meeting.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies and have paid the entire expense of preparing, printing, and mailing this proxy statement and any additional materials furnished to shareholders. In addition to solicitations by mail, our officers, directors, and employees may also solicit proxies in person, by telephone, or by other means of communication. Any officers, directors, and employees will not be paid any additional compensation for soliciting proxies. We will also reimburse brokerage firms, banks, and other agents for the cost of forwarding proxy materials to beneficial owners.

What does it mean if I receive more than one set of proxy materials?

If you receive more than one set of proxy materials, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions in each proxy card in the proxy materials, as applicable, to ensure that all of your shares are voted.

Can I change my vote or revoke my proxy after submission?

Shareholder of Record: Shares Registered in Your Name

Yes. You may revoke your proxy and change your vote at any time before the final vote at the Special Meeting. The cutoff time for voting through the internet or by telephone will be 11:59 P.M., Eastern Time, on , , 2022, the day before the Special Meeting. You may change your vote on the internet or by telephone (only your latest internet or telephone proxy submitted prior to the Special Meeting will be counted); by signing and returning a new proxy card with a later date; by sending a timely written notice that you are revoking your proxy to our Secretary at Armata Pharmaceuticals, Inc., 4503 Glencoe Avenue, Marina del Rey, California 90292; or by attending the Special Meeting and voting in person. However, your attendance at the Special Meeting will not automatically revoke your proxy unless you vote again at the Special Meeting or specifically request in writing that your prior proxy be revoked.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.

How are votes counted?

Votes generally. Votes will be counted by the inspector of election appointed for the Special Meeting, who will separately count, for each proposal, votes “For” and “Against,” abstentions, and, if applicable, broker non-votes.

Abstentions and Broker Non-Votes. Abstentions will count towards the quorum. Shares constituting broker “non-votes” are not counted or deemed to be present or represented for the purpose of determining whether shareholders have approved a matter or, unless the beneficial holder has provided voting instructions on at least one proposal, whether a quorum exists at the Special Meeting.

Required Vote. The following table summarizes the minimum vote needed to approve each proposal and the effect of abstentions and broker non-votes.

What is the quorum requirement?

A quorum of shareholders is necessary to hold a valid meeting. A quorum will be present if shareholders holding at least a majority of the outstanding shares entitled to vote on a matter and be counted collectively upon such matter are present at the Special Meeting in person or represented by proxy. On the record date, there were shares outstanding and entitled to vote. Thus, the holders of at least shares must be present in person or represented by proxy at the Special Meeting in order to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other agent) or if you vote in person at the Special Meeting. Abstentions will be counted towards the quorum requirement, but broker non-votes will not be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares at the Special Meeting present in person or represented by proxy may adjourn the Special Meeting to another date.

Could other matters be decided at the Special Meeting?

The Board knows of no other matters that will be presented for consideration at the Special Meeting. If any other matters are properly brought before the Special Meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.

How can I find out the results of the voting at the Special Meeting?

Preliminary voting results will be announced at the Special Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Special Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the Special Meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an amended Form 8-K to publish the final results.

How do Armata’s insiders intend to vote their shares?

All of Armata’s current directors and executive officers, and Innoviva and its affiliates, are expected to vote their shares of common stock in favor of all proposals. On the record date, Armata’s current directors and executive officers, and Innoviva and its affiliates, beneficially owned and were entitled to vote an aggregate of shares, representing approximately % of Armata’s issued and outstanding common stock.

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING INFORMATION

This Proxy Statement contains statements that constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Safe Harbor Provisions”), including statements about our beliefs or current expectations of our future financial prospects, operations and corporate governance procedures following the Private Placement with Innoviva LLC, as well as our current beliefs of our future prospects if the Second Closing does not occur, whether as a result of a failure of our shareholders to approve the Second Closing or otherwise. We intend the forward-looking statements throughout this Proxy Statement to be covered by the Safe Harbor Provisions for forward-looking statements. These forward-looking statements involve risks and uncertainties that could cause actual outcomes to differ materially from those expressed or implied in such forward-looking statements. The forward-looking statements are based on assumptions that the Company believes to be reasonable; however, risks and uncertainties associated with such assumptions are difficult to predict and in many cases may be beyond the control of the Company. Investors are cautioned not to place undue reliance on such forward-looking statements.

PROPOSAL 1

Approval of Private Placement

Background of the Proposal; Reasons for Seeking Shareholder Approval

We are submitting this proposal for shareholder approval in order to comply with certain provisions of the NYSE American rules applicable to us and to comply with the terms of the Purchase Agreement. Our Common Stock is listed on the NYSE American, which makes us subject to a variety of rules and requirements set forth in the NYSE American Company Guide (the “Company Guide”). The closing of the Second Placement, together with the First Placement, will result in the issuance of shares equal to 20% or more of the outstanding common stock of the Company for less than the greater of book or market value of the Company’s Common Stock, as required by and in accordance with the Company Guide Rule 713.

NYSE Private Placement Rule

Section 713 of the Company Guide requires us to obtain shareholder approval prior to the issuance of our Common Stock in connection with certain non-public offerings involving the sale, issuance or potential issuance by the Company of common stock (and/or securities convertible into or exercisable for common stock) equal to 20% or more of the common stock outstanding before the issuance. Shares of our Common Stock issuable upon the exercise or conversion of warrants, options, debt instruments, preferred stock or other equity securities issued or granted in such non-public offerings will be considered shares issued in such a transaction in determining whether the 20% limit has been reached. The closing of the Second Placement, together with the First Placement, will result in the issuance of shares equal to 20% or more of the outstanding common stock of the Company for less than the greater of book or market value of the Company’s Common Stock within the meaning of Company Guide Rule 713.

The issuance of shares of our Common Stock, or other securities convertible into shares of our Common Stock, in accordance with any offerings would dilute, and thereby reduce, each existing shareholder’s proportionate ownership in our Common Stock. Our existing shareholders, other than Innoviva, do not have preemptive rights to subscribe to additional shares that may be issued by the Company in private offerings in order to maintain their proportionate ownership of the Common Stock. In addition, the issuance of shares of Common Stock in one or more non-public offerings could have an anti-takeover effect. Such issuance could dilute the voting power of a person seeking control of the Company, thereby deterring or rendering more difficult a merger, tender offer, proxy contest or an extraordinary corporate transaction opposed by the Company.

Purchase Agreement and Private Placement

As previously disclosed, on February 9, 2022, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Innoviva Strategic Opportunities LLC (“Innoviva LLC”), a wholly-owned subsidiary of Innoviva, Inc. (Nasdaq: INVA) (collectively, “Innoviva”), pursuant to which the Company agreed to issue and sell to Innoviva LLC, in a private placement (the “Private Placement”), up to 9,000,000 newly issued shares (the “Shares”) of our common stock, par value $0.01 (the “Common Stock”), and warrants (the “Warrants”) to purchase up to 4,500,000 shares of Common Stock, with an exercise price per share of $5.00. The Purchase Agreement provides for the sale of the Shares and Warrants to Innoviva LLC in units, each consisting of one Share and one Warrant, for a per unit price of $5.00. Each Warrant is convertible into one-half Share of Common Stock.

Following the First Closing, the Company may be considered a “controlled company” under the rules of the NYSE American. As a controlled company, our Board of Directors (the “Board”) would no longer be required by the NYSE American to be composed of a majority of independent directors, and our Compensation Committee and Nominating and Corporate Governance Committee would no longer be required by the NYSE American to be composed solely of independent directors. We do not intend to take advantage of any of the foregoing exceptions to the NYSE American corporate governance requirements. Under the rules of the NYSE American and the SEC, our Audit Committee must continue to be composed solely of independent directors, regardless of whether or not Armata is a controlled company.

The foregoing descriptions of the terms of the Purchase Agreement, the Voting Agreement, the A&R IRA, and the Registration Rights Agreement are only a summary and are qualified in their entirety by reference to the full text of such agreements, which are attached to this proxy statement as Annex A, Annex B, Annex C, and Annex D, respectively.

If Proposal 1 is approved by our shareholders, Innoviva will be able to purchase the full amount of 9,000,000 newly issued Shares and Warrants to purchase up to 4,500,000 shares of Common Stock for less than the greater of book or market value of the Company’s Common Stock. Following the Second Closing, Innoviva would remain our largest shareholder, owning approximately 69.4% of the outstanding common

stock of the Company, assuming no exercise of the Warrants, and if Innoviva exercises all of the Warrants, it will own approximately 77.6% of the outstanding Common Stock of the Company.

We intend to use the net proceeds of the Private Placement for our U.S. Food and Drug Administration cleared first-in-human study, SWARM-P.a., which is evaluating the Company’s lead phage product candidate, AP-PA02, as a potential treatment for Pseudomonas aeruginosa airway infections in cystic fibrosis patients, and the expected clinical trial related to AP-SA02, a phage targeting Staphylococcus aureus, in patients with complicated bacteremia. We may also use a portion of the net proceeds from the Private Placement to in-license, acquire, or invest in complementary businesses, technologies, products, or assets. Our expected use of net proceeds from the Private Placement represents our current intentions based upon our present plans and business condition. As of the date of this proxy statement, we cannot currently allocate specific percentages of the net proceeds that we may use for the purposes specified above, and we cannot predict with certainty all of the particular uses for the net proceeds to be received upon the completion of the Private Placement, or the amounts that we will actually spend on the uses set forth above. The amounts and timing of our actual use of the net proceeds will vary depending on numerous factors, including our ability to obtain additional financing, the progress, cost and results of our preclinical and clinical development programs and single-patient expanded access program, and whether we are able to enter into future licensing or collaboration arrangements. We may find it necessary or advisable to use the net proceeds for other purposes, and our management will have broad discretion in the application of the net proceeds. Pending the use of the net proceeds from the Private Placement, we intend to invest the net proceeds in investment-grade, interest-bearing instruments.

If Proposal 1 is not approved by our shareholders, Innoviva will still hold approximately 19,691,561 shares of Common Stock and warrants to purchase up to approximately 16,672,043 shares of Common Stock, but will be unable to complete the Second Closing. In that case, we will not receive the additional proceeds of approximately $26.9 million from Innoviva as payment for the additional shares of common stock and additional warrants to purchase shares of common stock, and such funds will not be available to pursue the activities described above and substantially limit our growth potential.

Factors Considered by the Board in its Recommendation

The Board formed a qualified independent committee of directors comprised of Todd C. Peterson, Joseph M. Patti, and Robin C. Kramer to evaluate and approve an equity financing transaction of up to approximately $45.0 million. After careful consideration, the Board, acting upon the unanimous approval by and recommendation of the qualified independent director committee of the Board, the recommendation of the audit committee of the Board and reliance upon the fairness opinion issued by Ladenburg & Thalmann Co. Inc. determined that the Purchase Agreement and the transactions contemplated thereby, including the Private Placement, are expedient and in the best interests of us and our shareholders, and determined to recommend that our shareholders approve the Private Placement.

In making its determinations, the Board, acting upon the unanimous recommendation of the special committee of the Board and the recommendation of the audit committee of the Board considered various factors, including:

•

The recent performance of the Company’s stock price on the NYSE American.

•

and other terms and conditions of such sales, which revealed significant cost of such financing, assuming it could be obtained, to the Company and the associated significant dilution to its shareholders, which the Board determined was substantially less favorable to the Company than pursuing this transaction.

•

In consideration of the terms of a similarly structured private placement transaction with Innoviva and one other unrelated third-party investor which was concluded in October 2021.

•

Reliance upon the fairness opinion issued by Ladenburg & Thalmann Co. Inc., the Board’s financial advisor.

•

Restrictions under the Purchase Agreement on the Company’s ability to operate its business in the ordinary course until the consummation of the Second Closing.

•

Interests of the Company’s Directors and Executive Officers in the Private Placement

Our directors and executive officers may have interests in the Private Placement that are different from, or in addition to, yours. Mr. Haimovitz, Dr. Schlesinger and Dr. Kostas, are all affiliated with Innoviva and are expected to continue as members of the Board following the closing of the Private Placement.

Vote Required

The approval of Proposal 1 requires that the number of votes cast by shareholders, either in person or by proxy, “For” this proposal exceed the number of votes cast “Against” this proposal. Under exchange rules, abstentions and broker non-votes will count as a vote “Against” this proposal.

The Board of Directors Recommends
a Vote “For” Proposal 1.

PROPOSAL 2

Approval of Possible Adjournment of the Special Meeting

If the Special Meeting is convened and a quorum is not present, or if a quorum is present but there are not sufficient votes to approve Proposal 1, our proxy holders may move to adjourn the Special Meeting at that time in order to enable the Company to solicit additional proxies.

In this proposal, we are asking our shareholders to authorize and grant discretionary authority to the holder of any proxy solicited by this proxy statement to vote in favor of adjourning the Special Meeting to another time and place, if necessary, in order for the Company to solicit additional proxies in the event there are not sufficient votes to approve Proposal 1. If our shareholders approve this proposal, we would adjourn the Special Meeting and any adjourned session of the Special Meeting, if needed, and use the additional time to solicit additional proxies, including the solicitation of proxies from our shareholders that have previously voted. Among other things, approval of this proposal could mean that, even if we had received proxies representing a sufficient number of votes to defeat Proposal 1, we could adjourn the Special Meeting without a vote on such proposal and seek to convince our shareholders to change their votes in favor of such proposal. We currently do not intend to propose adjournment at the Special Meeting if there are sufficient votes to approve Proposal 1.

If it is necessary to adjourn the Special Meeting, no notice of the adjourned meeting is required to be given to our shareholders, other than an announcement at the Special Meeting of the time and place to which the Special Meeting is adjourned, so long as no new record date is fixed for the adjourned meeting. At the adjourned meeting, we may transact any business which might have been transacted at the original meeting.

Vote Required

The approval of Proposal 2 requires that the number of votes cast by shareholders, either in person or by proxy, “For” this proposal exceed the number of votes cast “Against” this proposal. Abstentions and broker non-votes will have no effect on this proposal.

The Board of Directors Recommends
a Vote “For” Proposal 2.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information regarding beneficial ownership of our capital stock by:

•

each person, or group of affiliated persons, known by us to beneficially own more than 5% of our Common Stock;

•

each of our current directors;

•

each of our executive officers; and

•

all of our current executive officers and directors as a group.

The percentage ownership information in the table below is based on 27,112,299 shares of Common Stock outstanding as of January 31, 2022.

Information with respect to beneficial ownership provided in the table below is based upon information supplied by officers and directors and based upon Schedules 13D and 13G and Forms 4 filed with the SEC. We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of Common Stock issuable pursuant to the exercise of stock options or warrants that are either immediately exercisable or exercised on or before April 1, 2022, which is 60 days after January 31, 2022. These shares are deemed to be outstanding and beneficially owned by the person holding those options or warrants for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.

Except as otherwise noted below, the address for each person or entity listed in the table is c/o Armata Pharmaceuticals, Inc., 4503 Glencoe Avenue, Marina del Rey, California 90292.

HOUSEHOLDING OF PROXY MATERIALS

The Commission has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for shareholder meeting materials with respect to two or more shareholders sharing the same address by delivering a single set of shareholder meeting materials addressed to those shareholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for shareholders and cost savings for companies.

A number of brokers with account holders who are Armata shareholders will be “householding” our proxy materials. A single set of shareholder meeting materials will be delivered to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate set of the shareholder meeting materials, please notify your broker or Armata. Direct your written request to Armata Pharmaceuticals, Inc., Attention: Investor Relations, 4503 Glencoe Avenue, Marina del Rey, California 90292 or contact Joyce Allaire at (212) 915-2569. If so requested, a separate copy of the shareholder meeting materials will be delivered to you promptly and without charge. Shareholders who currently receive multiple copies of the shareholder meeting materials at their addresses and would like to request “householding” of their communications should contact their brokers.

SHAREHOLDER PROPOSALS FOR THE 2022 ANNUAL MEETING OF SHAREHOLDERS

To be considered for inclusion in the proxy materials for the 2022 Annual Meeting of Shareholders, your proposal must be submitted in writing to our Secretary at Armata Pharmaceuticals, Inc., 4503 Glencoe Avenue, Marina del Rey, California 90292 by (i) December 29, 2021, or (ii) if the date of our 2022 Annual Meeting of Shareholders has changed by more than 30 days from the one-year anniversary of the date of the 2021 Annual Meeting of Shareholders, by a date that constitutes a reasonable time before we print and send our proxy materials to shareholders, which date will be disclosed in a report filed by us with the Commission. Any such proposals must meet the requirements of Rule 14a-8 under the Securities Exchange Act of 1934, as amended.

If you wish to submit a proposal (including a director nomination) that is not to be included in the proxy materials for the 2022 Annual Meeting of Shareholders, your proposal generally must be submitted in writing to the same address not fewer than 60 nor more than 90 days prior to the date approved by the Board to hold the 2022 Annual Meeting of Shareholders; provided, that if we provide less than 60 days’ notice of such date, your proposal (including a director nomination) must be received by our Secretary not later than the tenth day following the day on which the notice of the date of the 2022 Annual Meeting of Shareholders is mailed or publicly disclosed. Please review our Amended and Restated Bylaws, which contain additional requirements regarding advance notice of shareholder proposals and nominations.

OTHER MATTERS

The Board of Directors knows of no other matters that will be presented for consideration at the Special Meeting. If any other matters are properly brought before the Special Meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.

ARTICLE VII

TERMINATION

Section 7.1 Termination. This Agreement may be terminated, and the transactions contemplated hereby may be abandoned, at any time prior to the First Closing:

(a) by mutual written consent of the Company and the Purchaser;

(b) by the Company or the Purchaser, upon written notice to the other Party, if a Governmental Entity of competent jurisdiction has issued an Order or has taken any other action permanently enjoining or otherwise prohibiting the consummation of the transactions contemplated by this Agreement, and such Order or action has become final and non-appealable; provided, however, that the right to terminate this Agreement pursuant to this Section 7.1(b) shall not be available to any Party whose breach of any representation, warranty, covenant or other agreement contained in this Agreement is the primary cause of the failure to avoid such Order or other action; or

(i) (A) the Company has breached any representation, warranty, covenant or other agreement made by the Company in this Agreement or such representation or warranty shall have become inaccurate and such breach or inaccuracy would, individually or in the aggregate, cause a condition to the Second Closing to not be able to be satisfied, (B) the Purchaser shall have delivered written notice of such breach or inaccuracy to the Company and (C) such breach or inaccuracy is not cured by the Company before the 10th day following the delivery of such notice; or

(ii) the Company or any of its direct or indirect Subsidiaries (A) voluntarily commences any case or files any petition seeking bankruptcy, winding up, dissolution, liquidation, administration, moratorium, reorganization or other relief under any federal, state or foreign bankruptcy, insolvency, administrative receivership or similar law now or hereafter in effect; (B) consents to the

Upon delivery of a Second Closing Abandonment Notice, the obligation of each party to consummate the Second Closing shall terminate and no party shall thereafter be required to take any action contemplated herein necessary to cause the Second Closing to occur (the “Second Closing Abandonment”).

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below intending to be legally bound, the parties hereto agree as follows:

1. Certain Definitions. For all purposes of and under this Agreement, the following terms shall have the following respective meanings:

“Applicable Law” means with respect to any Person, any supranational, national, federal, state, provincial, local or other law, constitution, treaty, convention, statute, ordinance, code, rule, regulation or common law or other similar requirement enacted, adopted, promulgated or applied by any Governmental Authority, in each such case that is binding on or applicable to such Person, or its subsidiaries or its or their respective properties, assets or businesses.

B-1

“Business Day” means a day, other than Saturday, Sunday or other day on which commercial banks in New York, New York are authorized or required by Applicable Law to close.

“Common Shares” means all shares of Common Stock beneficially owned by Stockholders as of the date hereof (including the Purchased Shares and the Newly Purchased Shares) and as may be voluntarily acquired by Stockholders from time to time during the period from the Effective Date through the Expiration Date (including by the exercise of the Purchased Warrants).

“Expiration Date” means the earlier to occur of: (i) the second (2nd) anniversary of the Effective Date, and (ii) approval by the U.S. Food and Drug Administration of any of the product candidates of the Company for marketing and commercial distribution.

“Governmental Authority” means any supranational, national, federal, state, provincial, local or other government, department, authority, court, tribunal, commission, regulatory body or self-regulatory body (including any securities exchange), or any political or other subdivision, department, agency or branch of any of the foregoing.

“Order” means, with respect to any Person, any order, injunction, judgment, decision, determination, award, writ, ruling, stipulation, assessment or decree or other similar requirement of, or entered, enacted, adopted, promulgated or applied by, with or under the supervision of, a Governmental Authority or arbitrator, in each such case, that is binding upon or applicable to such Person or its subsidiaries or its or their respective properties, assets or businesses.

“Person” means any individual, general or limited partnership, corporation, limited liability company, business trust, joint stock company, trust, unincorporated organization, joint venture, firm, association or other entity or organization (whether or not a legal entity), including any Governmental Authority.

“Purchased Securities” means the Purchased Shares, the Newly Purchased Shares and the Purchased Warrants.

“Proceeding” means any suit (whether civil, criminal, administrative, judicial or investigative), claim, action, litigation, arbitration, mediation, proceeding (including any civil, criminal, administrative, investigative or appellate proceeding), hearing, audit, criminal prosecution, in each case commenced, brought, conducted or heard by or before, or otherwise involving, any court or other Governmental Authority or any mediator, arbitrator or arbitration panel.

2. Share Voting Cap.

(a) Following the Effective Date, at every meeting of the stockholders of the Company, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company in each case that are expressly for the purpose of electing directors to the board of directors (the “Board”) or removing directors from the Board or amending the bylaws of the Company to reduce the maximum number of directors or set the number of directors who may serve on the Board (collectively, “Board Matters”), the Stockholders (in their capacity as stockholders of the Company) shall not vote (including by written consent) any Common Shares held by the Stockholders collectively that exceed 49.5% of the total number of shares of Common Stock voting with respect to the applicable Board Matter at such meeting or in such action by written consent (the “Share Voting Cap”).

(b) Following the Effective Date, Common Shares held or otherwise beneficially owned by Stockholders in excess of the Share Voting Cap (“Excess Shares”) shall be voted at every meeting of the stockholders of the Company, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company, in each case solely with respect to Board Matters, only if the Board authorizes Stockholders to vote such Excess Shares and such authorization is confirmed in writing by the Company. If such authorization is given, and such confirmation is provided, the Stockholders shall be entitled to vote such Excess Shares in their sole discretion. By way of example, if 500 shares of Common Stock held by holders other than the Stockholders are voted with respect to any Board Matter, the Share Voting Cap with respect to such

B-2

Board Matter would be 490.1 Common Shares, and any Common Shares held by the Stockholders in excess of 490.1 would constitute Excess Shares.

(c) For the avoidance of doubt, nothing herein shall limit the Stockholders’ right to vote any Common Shares (including Excess Shares) in any manner that Stockholders may determine in their sole discretion with respect to any matters submitted to the vote (or written consent) of stockholders of the Company that are not Board Matters.

(d) Stockholders shall not enter into any agreement, arrangement or understanding with any Person to vote or give instructions in any manner inconsistent with the terms of this Section 2.

(e) In the event of any issuance of shares of the Company’s voting securities hereafter to a Stockholder or a Stockholder’s subsidiaries (including, without limitation, in connection with any stock split, stock dividend, recapitalization, reorganization, or the like), in relation to such Stockholder’s Common Shares, such additional shares shall automatically become subject to this Agreement and such Stockholder shall cause such subsidiary transferee to become a party to this Agreement by executing a joinder hereto.

3. Representations and Warranties of Stockholders. Stockholders hereby represent and warrant to the Company as follows:

(a) Ownership. Stockholders (i) are the beneficial owner of the Purchased Securities and will be the beneficial owner of any other Common Shares they may acquire; (ii) do not own as of the date hereof, of record or beneficially, any shares of capital stock of the Company (or rights to acquire any such shares) other than the Purchased Securities; and (iii) have the sole right to vote, dispose of and exercise and holds sole power to issue instructions with respect to the matters set forth in Section 2 hereof and sole power to agree to all of the matters set forth in this Agreement with respect to all of its Common Shares, subject to the terms of this Agreement.

This Agreement has been duly and validly executed and delivered by Stockholders, and, assuming this Agreement constitutes a valid and binding obligation of the Company, constitutes a valid and binding obligation of Stockholders, enforceable against Stockholders in accordance with its terms, except that such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar Applicable Laws affecting or relating to creditors’ rights generally and is subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or law).

(c) No Conflicts. The execution and delivery by Stockholders of this Agreement and the performance by Stockholders of its obligations hereunder will not: (i) result in a violation or breach of, or constitute (with or without notice or lapse of time or both) a default under, or conflict with any agreement to which either Stockholder is a party or by which the Purchased Securities are bound, or (ii) violate, or require any consent, approval, or notice under, any provision of any judgment, Order or decree or any Applicable Law that is applicable to either Stockholder or any of the Purchased Securities (other than filings required pursuant to securities laws), except, in the case of (i) or (ii) above, as would not reasonably be expected, either individually or in the aggregate, to impair the ability of Stockholders to perform their obligations hereunder on a timely basis.

4. Representations and Warranties of the Company. The Company hereby represents and warrants to Stockholders as follows:

(a) Power; Binding Agreement. The Company has the legal capacity and all requisite power and authority to execute and deliver this Agreement, to perform its obligations hereunder. This Agreement has been duly authorized, executed and delivered by the Company, and, assuming this Agreement constitutes a valid and binding obligation of Stockholders, constitutes a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except that such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium

B-3

and other similar Applicable Laws affecting or relating to creditors’ rights generally and is subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or law).

(b) No Conflicts. The execution, delivery, and performance of this Agreement by the Company will not (i) result in a violation or breach of, or constitute (with or without notice or lapse of time or both) a default under, or conflict with (A) any provisions of the certificate of incorporation or bylaws of the Company, (B) any contract to which the Company is a party or by which the Company’s assets or securities may be bound, or (ii) violate, or require any consent, approval, or notice under, any provision of any Order or any Applicable Law that is applicable to the Company or its assets or securities, except, in the case of (i) or (ii) above, as would not reasonably be expected, either individually or in the aggregate, to impair the ability of the Company to perform its obligations hereunder on a timely basis.

5. Further Assurances. Subject to the terms and conditions of this Agreement, each party hereto shall execute and deliver any additional documents and instruments and take, or cause to be taken, all actions, and do, or cause to be done, all things as may reasonably be deemed by the other party to be necessary or desirable to fulfill the intended purpose of this Agreement.

6. Effectiveness and Termination.

(a) Effectiveness. This Agreement shall become effective on the Effective Date.

(b) Termination. This Agreement, and all rights and obligations of the parties hereunder, shall terminate and shall have no further force or effect as of the Expiration Date.

(c) Survival. Notwithstanding the foregoing, nothing set forth in this Section 6 or elsewhere in this Agreement shall relieve any party hereto from liability, or otherwise limit the liability of any party hereto, for any material breach of this Agreement prior to such termination. This Section 6 and Sections 1 and 7 (as applicable) shall survive any termination of this Agreement.

7. Miscellaneous.

(a) Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated. Upon such a determination, the parties hereto agree to negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner, in order that substance of this Agreement be consummated as originally contemplated to the fullest extent possible.

(b) Binding Effect and Assignment. Neither this Agreement nor any of the rights, interests or obligations of Stockholders hereunder may be assigned by Stockholders (whether by operation of law or otherwise) without prior written consent of the Company. Notwithstanding the foregoing, either Stockholder may assign this Agreement and its rights, interests or obligations hereunder to an affiliate of such Stockholder without the consent of the Company. This Agreement and all of the provisions hereof shall be binding upon, inure to the benefit of and be enforceable by, the parties and their respective successors and permitted assigns and the provisions of this Agreement are not intended to confer upon any Person other than the parties hereto any rights or remedies hereunder.

(c) Amendments. This Agreement may be amended by the parties hereto only by an instrument in writing signed on behalf of each of the parties hereto.

(d) Specific Performance; Injunctive Relief. The parties hereto acknowledge that they will be irreparably harmed and that there shall be no adequate remedy at law for a violation of any of the covenants or agreements set forth herein. Therefore, it is agreed that, in addition to any other remedies that may be available to the non-breaching party at law, the non-breaching party shall have the right to enforce such covenants and agreements by specific performance, injunctive relief or by any other means available to it in equity, without the requirement of posting a bond or other security.

Reserved.

Participation Rights.

(a) Subject to the terms and conditions of this Section 3 and applicable securities or blue sky laws, if the Company proposes to offer or sell any New Securities, the Company shall first offer such New Securities to the Purchasers in accordance with the terms hereof.

(b) The Company shall give notice (the “Offer Notice”) to the Purchasers, stating (i) its bona fide intention to offer or sell such New Securities, (ii) the number of such New Securities to be offered, and (iii) the price and terms, if any, upon which it proposes to offer such New Securities.

(c) By written notification to the Company within thirty (30) days after the Offer Notice is delivered to the Purchaser, the Purchasers may elect to purchase or otherwise acquire, at the price and on the terms specified in the Offer Notice, up to that portion of such New Securities which equals the Purchaser’s Applicable Percentage. The failure of the Purchasers to deliver such written notice within such time period shall be deemed an election by the Purchasers not to exercise its purchase rights with respect to such Offer Notice. To the extent that the Company offers two (2) or more New Securities or other securities in units, the Purchasers must purchase such units as a whole and will not be given the opportunity to purchase only one of the securities making up such unit.

(d) The Company shall sell all applicable New Securities to the Purchasers or either of them if either Purchaser has elected to purchase such New Securities on a date to be mutually determined by the Company and the Purchasers (or either Purchaser), which date shall be not later than end of the ten (10) day period commencing at the expiration of the initial thirty (30) day election period; provided, however, that such ten (10) day period shall be extended automatically if any approvals or consents of any Governmental Entities are required to consummate the transaction and such approvals or consents are not received within such ten (10) day period for up to an additional one hundred twenty (120) days as long as such approvals or consents remain outstanding and the parties are continuing to exercise commercially reasonable efforts to obtain them.

(e) Upon the expiration of the offering period described in Section 3(d), the Company will be free to sell, during the one hundred twenty (120) day period commencing at the expiration of, as applicable, the

C-2

initial thirty (30) day election period following delivery of an Offer Notice (as may be extended in accordance with Section 3(d)), any New Securities that the Purchasers have not elected to purchase, at a sale price not less than, and on other terms no less favorable to the Company than, those offered to the Purchasers as set forth in the Offer Notice, provided, that such one hundred twenty (120) day period shall be extended automatically if any approvals or consents of any Governmental Entities are required to consummate the transaction and such approvals or consents are not received within such one hundred twenty (120) day period for up to an additional one hundred twenty (120) days as long as such approvals or consents remain outstanding and the parties are continuing to exercise commercially reasonable efforts to obtain them. Any New Securities offered or sold by the Company after such one hundred twenty (120) day period (as such period may be extended in accordance with the immediately preceding sentence) must be reoffered to the Purchasers pursuant to this Section 3.

(f) The election by the Purchasers not to exercise its subscription rights under this Section 3 in any one instance shall not affect its right (other than in respect of a reduction in its Applicable Percentage) as to any subsequent proposed issuance of New Securities under this Section 3. The provisions of this Section 3 shall apply equally to any issuance or sale by the Company or any of its Subsidiaries of equity securities that would be deemed New Securities if issued by the Company which, for the avoidance of doubt, shall not include any issuance of New Securities by a wholly-owned Subsidiary to the Company or to another wholly-owned Subsidiary of the Company. Subject to the terms of this Section 3, any sale of New Securities by the Company or any other entity covered by the preceding sentence without first giving the Purchasers the rights described in this Section 3 shall be null and void and of no force and effect.

(g) Notwithstanding the terms set forth in this Section 3, if the Board determines in good faith that the Company must issue New Securities on an expedited basis without prior compliance with the terms of this Section 3 in order to avoid material harm to the Company (an “Expedited Issuance”), then, subject to compliance with the terms of the immediately following sentence, the Company may effect and consummate such Expedited Issuance without complying with the terms set forth in this Section 3 and shall not be deemed to be in breach of this Section 3 as a result thereof. As promptly as practicable following the consummation of such Expedited Issuance, the Company and the Purchasers shall comply with the terms of this Section 3 in respect of the New Securities issued in such Expedited Issuance such that the Purchasers have the opportunity to participate in such Expedited Issuance of New Securities and be put in the same place (including in respect of the percentage ownership of the equity securities of the Company) they would have been had such Expedited Issuance been effected in accordance with the terms of this Section 3.

(h) (i) The provisions of this Section 3 (i) shall not apply to the issuance of Exempted Securities and (ii) shall terminate and be of no further force or effect as of such time that the Purchaser, together with its Affiliates, have an Applicable Percentage of less than 10%.

4. Board Matters.

(a) For so long as the Purchasers, together with their respective Affiliates and permitted assignees (collectively, the “Investors”) have an Applicable Percentage of at least 8%, the Company shall cause the Board to consist of not more than eight (8) members without the prior written consent of the Investors (which shall not be unreasonably withheld).

(b) For so long as the Investors have an Applicable Percentage of at least 12.5%, the Investors shall have the right to designate two (2) directors to the Board, and for so long as the Investors, collectively, and together with their Affiliates, continue to have an Applicable Percentage of at least 8% but less than 12.5%, the Investors shall have the right to designate one (1) director to the Board, in each case, in accordance with the terms of this Section 4. Any directors designated by the Investors in accordance with this Section 4 shall be referred to as “Investor Designees”. As of the date of this Agreement, Dr. Odysseas Kostas MD and Jules Haimovitz are the Investor Designees. The right to designate one (1) or more Investor Designees shall terminate and be of no further force or effect as of such time that the Investors have an Applicable Percentage of less than an applicable threshold percentage referenced in the first sentence of this Section 4(b). At any point in which the Investors are entitled to designate an Investor Designee, the Investors may provide written notice (a “Designation Notice”) to the Company naming the applicable Investor Designee(s) and demanding that the applicable Investor Designee(s) be appointed to the Board. Promptly, and in any event within five (5) Business Days, following receipt of the Designation Notice, the Company shall (i) cause a number of

C-3

existing members of the Board equal to the number of Investor Designees so designated to resign from the Board and (ii) cause the Investor Designees to be appointed to the Board. Following the delivery of a Designation Notice and prior to the appointment of the Investor Designees to the Board, the Company shall not (and shall cause its Subsidiaries not to) take or approve any action outside of the ordinary course of business including (without limitation) in respect of:

(i) strategic transactions, joint ventures and collaborations;

(ii) sale or acquisition of assets or shares of the Company or any of its Subsidiaries, whether by merger, consolidation or otherwise;

(iii) issuance of equity or debt securities;

(iv) incurrence or prepayment of indebtedness;

(v) declaration or payment of any dividend or distribution;

(vi) amendment of any provision of this Agreement or any other governing documents of the Company or any of its Subsidiaries in a manner that would be inconsistent with the provisions of this Agreement;

(vii) any change to the Company’s or any Subsidiary’s legal form, domicile or tax structure, or make any material change to the Company’s accounting or tax policies or practices; or

(viii) amend or alter the compensation of any of the Company’s or Subsidiary’s executives.

(c) With respect to any vote of the Board, each director shall have one (1) vote and approval of all matters shall require the affirmative vote of a majority of directors.

(d) Subject to the terms of this Section 4, from and after the date hereof, the Company shall take all action within its power to cause the covenants set forth in Section 4(a) and Section 4(b) to be fulfilled in all respects including: (i) causing the Investor Designees to be named in any proxy statement of the Company with respect to the election of members of the Board, (ii) soliciting the votes of shareholders in respect of the Investor Designees in the same manner and with the same level of effort as with the solicitation in respect of other members of the Board, (iii) seeking to amend any organizational documents of the Company necessary to give effect to the Investors’ rights hereunder as may reasonably be requested by the Investors and (iv) take all actions permitted by applicable law to cause the Investor Designees to be members of the Board (including the appointment of the Investor Designees to the Board).

(e) Subject to clause (f) immediately below, in the event that an Investor Designee ceases to serve on the Board for any reason (including the death, disability or resignation of such person), the Investors shall be entitled to appoint a new Investor Designee in the place of such person, and the terms of this Section 4 shall apply equally to such replacement.

(f) In the event that the Applicable Percentage of the Investors falls below a threshold set forth in Section 4(b) such that the Investors shall lose the right to designate one or more Investor Designees, if one or more Investor Designee has been designated, the Investors shall identify, if applicable, which of the Investor Designees shall no longer be an Investor Designee (such person, a “Departing Designee”), and which Investor Designee(s) (if any) will remain as such; for the avoidance of doubt, the terms of this Section 4 shall continue to apply to any Investor Designee who is not a Departing Designee. In the event of a Departing Designee, the Investors shall cause the removal or resignation of such Departing Designee prior to the next annual meeting of the Company shareholders, and the provisions of Section 4(b) and (c) shall not apply to such Departing Designee, and in connection therewith, the Company shall not be required to name such Departing Designee on its proxy statement or solicit votes in favor of such Departing Designee.

(g) For so long as the Investor holds the Applicable percentages set forth above, in the event that any member of the Board serves on the board of directors or similar governing body of any Subsidiary of the Company (a “Subsidiary Board”) or in the event that any shareholder of the Company has appointed or designated a person to serve on a Subsidiary Board, the Investors shall be entitled to designate a number of Investor Designees to the Subsidiary Board equal to the greater of (x) one Investor Designee or (y) such

C-4

other number of Investor Designees such that the proportionate representation of Investor Designees on such Subsidiary Board approximates, as closely as possible, the proportionate representation of Investor Designees on the Board. Subject to applicable law and listing requirements, the Investor Designees shall be entitled to be a member of any committee of the Board (including an executive or similar committee).

(h) Any person designated by the Investor as an Investor Designee must possess the requisite financial and business experience to serve as a director of the Company (it being understood that the directors and each of the executives and investment professionals employed by the Investor or its Affiliates shall be deemed to possess such experience). If the Board and all applicable committees of the Board reasonably determine that an Investor Designee satisfies the criteria in the foregoing sentence, the Board shall nominate and appoint such Investor Designee to the Board.

(i) For purposes of this Section 4, whenever the action of the Investors is required, such action shall be effected by vote of Investors holding a majority of the Common Stock held by all Investors.

5. Information and Confidentiality.

(a) The Company shall provide to Purchasers all information and documentation reasonably requested by Purchasers, within the periods reasonably requested by Purchasers, as is necessary for the Purchasers to complete and file all public filings required to be made by Purchasers under applicable Law and the rules and regulations of the Securities Exchange Commission.

(b) The Purchasers agrees that they will keep confidential and will not disclose or divulge any confidential information obtained from the Company pursuant to the terms of this Agreement, unless such confidential information (a) is known or becomes known to the public in general (other than as a result of a breach of this Section 5 by either Purchaser), (b) is or has been independently developed or conceived by either Purchaser without use of the Company’s confidential information, or (c) is or has been made known or disclosed to either Purchaser by a third party without a breach of any obligation of confidentiality such third party may have to the Company; provided, however, that the Purchasers may disclose confidential information (i) to their attorneys, accountants, consultants and other professionals to the extent necessary to obtain their services in connection with matters related to the Company; (ii) to any prospective purchaser of any Registrable Securities from either Purchaser, if such prospective purchaser agrees to be bound by the provisions of this Section 5; (iii) to any of their respective Affiliates or their or such Affiliates’ general or limited partners, members, stockholders, employees, officers or directors, in the ordinary course of business, provided that the applicable Purchasers informs such person that such information is confidential and directs such person to maintain the confidentiality of such information; or (iv) as may otherwise be required by law, regulation, rule, court order, arbitration order or subpoena, provided that the applicable Purchaser promptly notifies the Company of such disclosure and takes reasonable steps to minimize the extent of any such required disclosure. The Purchasers acknowledge and agree that the securities laws of the United States and other jurisdictions contain prohibitions on the trading in the securities of the Company while in possession of material nonpublic information regarding the Company, and agree to comply with such restrictions.

6. Miscellaneous.

(a) Amendments and Waivers. This Agreement may be amended only by a writing signed by the Company and the Purchasers. The failure or delay in enforcing compliance at any time with respect to any of the provisions, terms or conditions of this Agreement shall not be considered a waiver of such provision, term or condition itself or of any of the other provisions, terms or conditions hereof.

(b) Notices. All notices and other communications provided for or permitted hereunder shall be made as set forth in the Purchase Agreements.

(c) Assignments and Transfers by the Purchasers. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and permitted assigns. The Purchasers may transfer or assign, in whole or from time to time in part, to one or more persons their rights hereunder in connection with the transfer of Company Common Stock or Warrants by the Purchasers to such person, provided that the Purchasers comply with all laws applicable thereto and the provisions of the applicable Purchase Agreement and the Warrant and provide written notice of assignment to the Company

C-5

prior to such assignment or transfer being effected, and such transferee agrees in writing and as a condition to the receipt of the Company Common Stock or Warrants to be bound by all of the provisions contained herein.

(d) Assignments and Transfers by the Company. This Agreement may not be assigned by the Company (whether by operation of law or otherwise) without the prior written consent of the Purchasers; provided, however, that in the event that the Company is a party to a merger, consolidation, share exchange or similar business combination transaction in which the Company Common Stock are converted into the equity securities of another person, from and after the effective time of such transaction, such person shall, by virtue of such transaction, be deemed to have assumed the obligations of the Company hereunder, and the term “Company” shall be deemed to refer to such person and the term “Company Common Stock” shall be deemed to include the securities received by the Purchasers in connection with such transaction unless such securities are otherwise freely tradable by the Purchasers after giving effect to such transaction.

(h) Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof but shall be interpreted as if it were written so as to be enforceable to the maximum extent permitted by applicable law, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereby waive any provision of law which renders any provisions hereof prohibited or unenforceable in any respect.

(i) Further Assurances. The parties shall execute and deliver all such further instruments and documents and take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained.

(j) Entire Agreement.

This Agreement supersedes all prior agreements and understandings between the parties with respect to such subject matter.

(k) Specific Performance. Without limiting remedies that may be available at law or in equity, the parties acknowledge that any failure by any party to comply with their respective obligations under this Agreement would result in material irreparable injury to the other party for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the non-breaching party may specifically enforce the breaching party’s obligations under this Agreement without the need to show actual damages and without the need to post a bond or other security.

(l) Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware without regard to the choice of law principles thereof.

C-6

irrevocably submits to the exclusive jurisdiction of such courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or other proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding.

The Holder agrees to furnish such information to the Company and to cooperate with the Company as reasonably necessary to enable the Company to comply with the provisions of this Agreement.

(b) In connection with any Registration Statement filed by the Company pursuant to Section 2(a) hereof in which the Holder has registered for sale its Registrable Securities, the Holder agrees to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors and officers, employees, agents and each Person who controls the Company (within the meaning of the Securities Act or the Exchange Act) (collectively, “Holder Indemnified Persons”, and together with the Company Indemnified Persons, each an “Indemnified Person”, and collectively, the “Indemnified Persons”) from and against any Losses resulting from (i) any untrue or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Securities were registered or sold under the Securities Act, Prospectus (including in any preliminary prospectus (if used prior to the effective date of such Registration Statement)), or in any summary or final prospectus or in any amendment or supplement thereto or in any documents incorporated by reference in any of the foregoing, (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the Prospectus, in light of the circumstances under which they were made) not misleading, or (iii) any violation or alleged violation by the Holder of any federal, state or common law rule or regulation relating to action or inaction in connection with any information provided by the Holder in such registration, disclosure document or related document or report in the case of clauses (i) and (ii) to the extent, but only to the extent, that such untrue statement or omission occurs in reliance upon and in conformity with any information furnished in writing by or on behalf of the Holder specifically for inclusion in such registration, disclosure document or related document or report and has not been corrected in a subsequent writing prior to the sale of the Registrable Securities thereunder, and the Holder will reimburse the Company for any legal or other expenses reasonably incurred by it in connection with investigating or defending such Losses. In no event shall the liability of the Holder hereunder be greater in amount than the dollar amount of the net proceeds received by the Holder under the sale of Registrable Securities giving rise to such indemnification obligation.

D-8

(c) Any Indemnified Person under paragraph (a) or (b) of this Section 5 shall (i) give prompt written notice to the indemnifying person under paragraph (a) or (b) of this Section 5 of any claim with respect to which it seeks indemnification (provided that any delay or failure to so notify the indemnifying person shall not relieve the indemnifying party of its obligations hereunder except to the extent, if at all, that the indemnifying person’s ability to defend such claim (through the forfeiture of substantive rights or defenses) is actually and materially prejudiced by reason of such delay or failure) and (ii) permit such indemnifying person to assume the defense of such claim with counsel reasonably satisfactory to the Indemnified Person; provided, however, that any Indemnified Person shall have the right to select and employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (A) the indemnifying person has agreed in writing to pay such fees or expenses, (B) the Indemnified Person has reasonably concluded (based upon advice of its counsel) that there may be legal defenses available to it or other Indemnified Persons that are different from or in addition to those available to the indemnifying person, or (C) in the reasonable judgment of any such Indemnified Person (based upon advice of its counsel) a conflict of interest may exist between such Indemnified Person and the indemnifying person with respect to such claims (in which case, if the Indemnified Person notifies the indemnifying person in writing that such Indemnified Person elects to employ separate counsel at the expense of the indemnifying person, the indemnifying person shall not have the right to assume the defense of such claim on behalf of such Indemnified Person). If any action is settled or if there be a final judgment for the plaintiff, the indemnifying person agrees to indemnify each Indemnified Person from and against any Losses by reason of such settlement or judgment. No action may be settled without the written consent of the Indemnified Person (which consent shall not be unreasonably withheld, delayed or conditioned), provided that the consent of the Indemnified Person shall not be required if (A) such settlement includes an unconditional release of such Indemnified Person in form and substance satisfactory to such Indemnified Person from all liability on the claims that are the subject matter of such settlement; (B) such settlement provides for the payment by the indemnifying person of money as the sole relief for such action and (C) such settlement does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person. It is understood that the indemnifying person or persons shall not, except as specifically set forth in this Section 5(c), in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements or other charges of more than one separate firm (in addition to any local counsel that is required to effectively defend against any such proceeding) for all Indemnified Persons and that all such fees and expenses shall be paid or reimbursed promptly.

(d) If the indemnification provided for in this Section 5 is held by a court of a competent jurisdiction to be unavailable to an Indemnified Person with respect to any loss, damage, claim or liability, the indemnifying party, in lieu of indemnifying such Indemnified Person thereunder, shall to the extent permitted by law, contribute to the amount paid or payable by such Indemnified Person as a result of such loss, damage, claim or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the Indemnified Person on the other in connection with the actions that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying person and of the Indemnified Person shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying person or Indemnified Person and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Parties agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding sentences. Notwithstanding the provisions of this Section 5(d), the Holder shall not be required to contribute any amount in excess of the net proceeds (after deducting the underwriters’ discounts and commissions) received by it in the offering. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

(e) The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. The obligations of the Company and the Holder under this Section 5 shall survive completion of any offering of Registrable Securities pursuant to a Registration Statement and the termination of this Agreement.

The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

(b) Amendment; Modification; Waivers. This Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed by the Company and the Holder, which writing shall specifically reference this Agreement, specify the provision(s) hereof that it is intended to amend or waive and further specify that it is intended to amend or waive such provision(s).

(c) Notices.

(d) Governing Law; Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws. In any action or proceeding between any of the parties arising out of or relating to this Agreement, each of the parties: (a) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Delaware Chancery Court or, to the extent such court does not have subject matter jurisdiction, the United States District Court sitting in the State of Delaware; (b) agrees that all claims in respect of such action or proceeding shall be heard and determined exclusively in accordance with clause (a) of this Section 7(d); (c) waives any objection to laying venue in any such action or proceeding in such courts; (d) waives any objection that such courts are an inconvenient forum or do not have jurisdiction over any party hereto; and (e) irrevocably and unconditionally waives the right to trial by jury.

(e) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective heirs, executors, administrators, successors, legal representatives, and permitted assigns.

(g) Waiver of Trial by Jury. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT OR IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PERSON HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PERSON MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT.

(h) Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision hereof shall not affect the validity or enforceability of any other provision. Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement, or the application thereof to any Person or any circumstance, is invalid or unenforceable, (i) a suitable and equitable provision shall be substituted therefor to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (ii) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction; provided, that, if any one or more of the provisions contained in this Agreement shall be determined to be excessively broad as to activity, subject, duration or geographic scope, it shall be reformed by limiting and reducing it to the minimum extent necessary, so as to be enforceable under applicable law.

(i) Business Days. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall be a day other than a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.

(j) Entire Agreement. This Agreement constitutes the entire agreement among the Parties with respect to the subject matter hereof and supersedes all prior contracts or agreements with respect to the subject matter hereof and supersedes any and all prior or contemporaneous discussions, agreements and understandings, whether oral or written, that may have been made or entered into by or among any of the Parties or any of their respective Affiliates relating to the transactions contemplated hereby.

(k) Execution of Agreement. This Agreement may be executed and delivered (by facsimile, by electronic mail in Adobe Portable Document Format (.pdf) or otherwise) in any number of counterparts, each of which, when executed and delivered, shall be deemed an original, and all of which together shall constitute the same agreement.

(l) Determination of Ownership. In determining ownership of Company Common Stock hereunder for any purpose, the Company may rely solely on the records of the transfer agent for the Company Common Stock from time to time, or, if no such transfer agent exists, the Company’s stock ledger.

(m) No Recourse. Notwithstanding anything that may be expressed or implied in this Agreement, each Party covenants, agrees and acknowledges that no recourse under this Agreement or any documents or instruments delivered in connection with this Agreement shall be had against any of the Company’s or the Holder’s former, current or future direct or indirect equity holders, controlling persons, stockholders, directors, officers, employees, agents, Affiliates, members, financing sources, managers, general or limited partners or assignees (each, a “Related Person” and collectively, the “Related Persons”), in each case other than the Company, the Holder or any of their respective permitted assigns under this Agreement, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any of the Related Persons, as such, for any obligation or liability of the
