The Purchase Agreement required the Issuer immediately after its execution to use reasonable best efforts to deliver an irrevocable stockholder written consent (the “Written Consent”) executed by Gary Winemaster and Kenneth Winemaster, the Issuer’s majority controlling stockholders (the “Founding Stockholders”), consenting to the adoption of resolutions approving the conversion of the Series B Preferred Stock into Common Stock, the issuance of Common Stock and/or Series B Preferred Stock upon the exercise of the 2018 Warrant and the Additional Warrant (as defined in Item 4 below), and the proxy, board representation and voting rights set forth in the Shareholders Agreement and the Investor Rights Agreement (collectively, the “Stockholder Proposal”).

Series B Preferred Stock

On March 31, 2017, pursuant to the Purchase Agreement, the Issuer issued to Weichai America 2,385,624 shares of Series B Preferred Stock, with rights, preferences and designations set forth in a Certificate of Designation of Series B Convertible Perpetual Preferred Stock (the “Certificate of Designation”) filed with the Secretary of State of the State of Delaware on March 30, 2017.

Effective as of the close of business on the effectiveness of the approval of the Stockholder Proposals which include proposals to issue Common Stock upon conversion of the Series B Preferred Stock and exercise of the 2018 Warrant and the Additional Warrant for purposes of Nasdaq Listing Rule 5635 (the “Stockholder Approval Date”), each share of Series B Preferred Stock will automatically, without any action of the holder thereof, convert into a number of shares of Common Stock equal to the aggregate liquidation preference of such share of Series B Preferred Stock (but excluding any accrued but unpaid dividends, which shall be cancelled upon such conversion) divided by the conversion price then in effect. The Series B Preferred Stock is not otherwise convertible into shares of Common Stock.

The conversion price of the Series B Preferred Stock is initially equal to $8.00 per share of Common Stock (so each share of Series B Preferred Stock initially converts into two shares of Common Stock). The conversion price of the Series B Preferred Stock is subject to adjustment upon the occurrence of any of the following events: (i) the payment of distributions payable in Common Stock; (ii) the issuance to all holders of Common Stock of certain options, warrants or other rights entitling them to subscribe for or purchase Common Stock for a period expiring within 60 days from the date of issuance of such options, warrants or other rights at a price per share of Common Stock less than 100% of the market value on the date fixed for the determination of stockholders of the Issuer entitled to receive such options, warrants or other rights; (iii) subdivisions, splits or reclassifications of the Common Stock into a greater number of Common Stock; (iv) distributions to all holders of outstanding Common Stock, including evidences of indebtedness, assets or securities, but excluding any dividends or distributions of options, warrants or other rights referred to in (i) or (ii) above, dividends and distributions paid exclusively in cash; (v) dividends and distributions of capital stock or equity interests in connection with spin offs; and (vi) a tender or exchange offer that requires a payment in excess of the closing sales price for the Common Stock.

Prior to 180 days after the Closing Date (the “Accrual Date”), holders of the Series B Preferred Stock will participate equally and ratably with the holders of shares of Common Stock in all dividends on the shares of Common Stock on an as converted basis. Commencing on the Accrual Date, holders of Series B Preferred Stock shall be entitled to quarterly cumulative dividends and if declared will be payable quarterly in cash on January 15, April 15, July 15 and October 15 of each year at the annual rate of 10% of the $16.00 per share liquidation preference. Such dividends shall be declared and payable unless the Issuer is not permitted to declare or pay such dividend or incur such liability either (x) as a matter of law or (y) under the terms of the Issuer’s debt financing agreements. In the event any dividends on the Series B Preferred Stock are prohibited from being declared or paid by the Issuer, all deferred dividends shall be payable on the first dividend payment date when the Issuer is no longer being prohibited from doing so.

The Series B Preferred Stock contains limitations on the Issuer’s ability to pay distributions on its shares ranking, as to the payment of distributions or rights upon the Issuer’s liquidation, dissolution or winding up, on a parity with or junior to the Series B Preferred Stock, including the Common Stock, for any period unless all accrued and unpaid dividends all have been or contemporaneously are declared and paid, or are declared and a sum of cash sufficient for the payment thereof is set apart for such payment.

In the event of voluntary or involuntary liquidation, dissolution or winding-up of the Issuer, the holders of the Series B Preferred Stock will be entitled to receive out of the assets of the Issuer available for distribution to stockholders of the Issuer, before any distributions on the Common Stock or any other junior stock, an amount equal to the greater of the liquidation preference plus accrued and unpaid dividends, or the amount that would otherwise be payable on an as converted basis assuming the conversion of the Series B Preferred Stock into Common Stock.

If, upon the Issuer’s liquidation, winding-up or dissolution, the assets are insufficient to make the full payment due to holders of the Series B Preferred Stock, no distribution of assets shall be made on any junior stock, and no distribution shall be made in respect of any parity stock unless the Series B Preferred Stock shares ratably in any such distribution.

Page 7 of 14

Upon the election of the holder, the Issuer is obligated to redeem the Series B Preferred Stock at any time after March 31, 2018, first anniversary of the Closing Date, an obligation that will be extinguished upon the automatic conversion of the Series B Preferred Stock into Common Stock on the Stockholder Approval Date.

Pursuant to the terms of the Purchase Agreement, the Issuer must ensure that the Stockholder Proposal is approved by way of written consent of the Issuer’s stockholders within one hundred eighty (180) days following the Closing Date. In the event that the Issuer is unable to obtain, as a matter of law, the approval of the Stockholder Proposal by written consent within one hundred eighty (180) days following Closing Date, at the request of Weichai America, the Issuer is required to immediately call and hold a meeting of its stockholders for the purpose of approving the Stockholder Proposal no less than once in each three (3)-month period beginning on the one hundred eightieth (180) days following Closing Date until the Stockholder Proposal has been duly approved.

The holders of Series B Preferred Stock do not have any voting rights, including the right to elect any directors, except for voting rights required by law or those explicitly provided in the Certificate of Designations, which solely include voting rights with respect to (i) any amendment of the Certificate of Incorporation if the amendment would alter or change the powers, preferences, privileges or rights of the holders with respect to Series B Preferred Stock so as to affect them adversely, (ii) issuances or any class of securities that would have parity with or be senior to the Series B Preferred Stock, or (iii) reclassifications of any authorized stock of the Issuer into any parity stock or senior stock, or any obligation or security convertible into or evidencing a right to purchase any senior stock.

The Warrants

On March 31, 2017, pursuant to the Purchase Agreement, the Issuer issued to Weichai America the 2018 Warrant, pursuant to which Weichai America (including any permitted transferee or assignee of the 2018 Warrant under the terms thereof) has the right to purchase from the Issuer, the sum of (a) 4,055,709 shares of Common Stock, and (b) any additional shares of Common Stock so that after the full and complete exercise of the 2018 Warrant (including the aggregate number of shares of Common Stock previously issued from time to time as a result of any partial exercise of the 2018 Warrant), Weichai America, together with all of its affiliates and all persons to which it or its affiliates have transferred any shares of Common Stock or Series B Preferred Stock acquired under the Purchase Agreement, hold an aggregate number of shares of Common Stock (assuming the conversion of Series B Preferred Stock into Common Stock as of such time of such exercise) equal to 51% of the Common Stock deemed outstanding on the date of final exercise of the Warrant in full, subject to adjustment as provided therein.

The 2018 Warrant will become exercisable for a three-month period commencing upon the 18 month anniversary of the Closing Date, provided, however, that the 2018 Warrant may become exercisable prior to such date to the extent that the Issuer is in default under certain of its debt obligations and the Issuer’s lenders accelerate such obligations. The 2018 Warrant will be exercisable at a price per share of Common Stock equal to 85% of the volume weighted average price of the Common Stock (“VWAP”) during the 20 consecutive trading day period preceding the date of exercise, or 50% of such preceding VWAP price if the Issuer is delisted from Nasdaq as of the 18 month anniversary of the Closing Date (and if the 2018 Warrant is exercised prior to such date, the exercise price shall be appropriately adjusted depending on whether the Issuer is or is not delisted from Nasdaq on such date). The 2018 Warrant exercise price is subject to further reduction pursuant to a formula that provides for such adjustment in case the Issuer’s 2017 adjusted EBITDA is less than $22,000,000 or its net book value per share as of December 31, 2016 is less than $8.00 (in each case as determined from the Issuer’s audited financial statements for such fiscal years), provided that the aggregate amount of such downward adjustments in the 2018 Warrant exercise price shall not exceed $15,000,000. If the Stockholder Proposal has not been approved prior to the exercise of the 2018 Warrant, the 2018 Warrant shall be exercisable for a number of shares of Series B Preferred Stock (instead of Common Stock) which are convertible into the number of shares of Common Stock for which the 2018 Warrant would otherwise be exercisable. In addition, if the Issuer is obligated to issue shares to resolve a specified dispute following the 18 month anniversary of the Closing Date, the Issuer will issue to Weichai America an additional Warrant (the “Additional Warrant”) to offset the dilutive effect of such issuance, and the terms of such Additional Warrant shall be similar to the terms of the 2018 Warrant.

Investor Rights Agreement

The Investor Rights Agreement provides Weichai America with representation on the Issuer’s board of directors (the “Board”) and management representation rights. On the Closing Date, the Issuer increased the size of its Board to seven and appointed two individuals designated by Weichai America to its Board, one of whom is serving as the chairman of the Board. Thereafter, the Rights Agreement requires the Issuer to nominate for election to the Board three individuals designated by Weichai America and use best efforts to cause their election in connection with each annual meeting of stockholders of the Issuer. Subject to applicable law and applicable stock exchange requirements, Weichai America shall have the right to designate at least three (3) directors, two (2) directors or one (1) director, respectively, for election to the Board for so long as it beneficially owns securities representing, in the aggregate, no less than 30%, 20%, and 10%, respectively, of the total outstanding Common Stock (calculated on a fully-diluted as-converted basis and excluding all Issuer securities issued pursuant to certain exceptions as provided therein). Upon the exercise of the 2018 Warrant in full, and so long as Weichai America beneficially owns at least 40% of the outstanding shares of Common Stock (calculated on a fully-diluted as-converted basis and excluding all Issuer securities issued pursuant to certain exceptions as provided therein), the Issuer shall cause the appointment to the Board of one additional individual designated by Weichai America, and Weichai America shall thereafter have the right to nominate for election four directors or any additional number of designees necessary to ensure that its designees constitute the majority of the directors serving on the Board. The Issuer also agreed in the Investor Rights Agreement, that during any period when the Issuer is a “controlled company” within the meaning of the NASDAQ Listing Rules, it will take such measures as to avail itself of the “controlled company” exemptions available to it under Rule 5615 of the Nasdaq Listing Rules of Rules 5605(b), (d) and (e).

Pursuant to the management representation rights contained in the Investor Rights Agreement, Weichai America has the right to appoint an individual to serve in a management role as a vice president of the Issuer (or such position with an equivalent role and title), and once appointed, such individual shall be primarily responsible for overseeing the collaboration between the Issuer and Weichai Power under the Collaboration Agreement. The Investor Rights Agreement also requires the Issuer to promptly inform and consult with Weichai America regarding the recruitment of the chief executive officer, chief financial officer, and chief operating officer of the Issuer, and provides Weichai America with the right to propose candidates for such positions.

Weichai America has certain governance rights under the Investor Rights Agreement. The Investor Rights Agreement requires the Issuer to provide notice and consult with Weichai America before taking any of the following actions: (a) creating, participating or terminating any partnership, joint venture, consortium or similar business arrangement, (b) approving the annual budget and business plan and material amendments thereof, (c) causing or permitting encumbrances except as contemplated in the approved annual budget plan, on assets with value not in excess of $500,000 or arising in the ordinary course of business under law, (d) appointing, removing or replacing any “C-suite level” executive and (e) approving, amending, modifying or terminating any employee equity incentive plans. Following consultation with Weichai America, the Issuer is permitted to take the foregoing actions if approved by a majority of the Board (including one director designated by Weichai America). The following actions require the approval of Weichai America or a director designated by Weichai America: (i) declaration of dividends and other distributions, (ii) the creation of any new class of equity security, the repurchase, redemption or retirement of equity securities and the amendment of the rights, preferences and privileges of any equity security and (iii) the increase or decrease in the size of the Board other than to increase the size to seven on the Closing Date as contemplated under the Purchase Agreement and the Investor Rights Agreement.

The Investor Rights Agreement also contains customary standstill restrictions which prohibit Weichai America, the Founding Stockholders and each of their respective affiliates from acquiring beneficial ownership of additional shares of Common Stock (excluding certain limited exceptions) or taking other specified actions with respect to the Issuer until the earlier of (a) three (3) years following Closing Date, (b) the date when Weichai exercises the 2018 Warrant in full, or (c) the occurrence of a change of control sale event, other than certain limited exceptions or with the consent of at least seventy-five percent (75%) of the members of the Board.

Weichai America also has certain registration rights with respect to the Common Stock for so long as it beneficially owns a number of Common Stock (including Common Stock issuable upon conversion of the Series B Preferred Stock) that, in aggregate, is equal to at least 5% of the Common Stock of the Issuer. These include demand registration right and piggyback registration rights. The Issuer is obligated to pay all registration expenses (other than underwriting discounts and selling commissions) in connection with any demand registration or piggyback registration.

Page 9 of 14

The Investor Rights Agreement also provides Weichai America with preemptive rights pursuant to which Weichai America has a right to purchase a pro rata portion of any new issue of securities issued by the Issuer, including Common Stock (excluding certain excepted issuances).

Shareholders Agreement

Concurrent with the Purchase Agreement, the Issuer, Weichai America, and the Founding Stockholders entered into a Shareholders Agreement which requires, inter alia, the Founding Stockholders to refrain from revoking or seeking to revoke the Written Consent and to reject any other transaction, proposal, agreement or action which is made in opposition to the Stockholder Proposal or in competition or inconsistent with the Stockholder Proposal. The Shareholders Agreement prohibits the Founding Stockholders from voting on certain prescribed fundamental corporate matters unless previously agreed in writing by Weichai America and obligates the Founding Stockholders to not vote to remove any of the directors designated by Weichai America for election to the Board, or vote on any action to reduce or increase the size of the Board, and requires the Founding Stockholders to vote in favor of the individuals designated by Weichai America for election to the Board at any annual or special meeting of stockholders or in connection with any action by written consent in lieu of any such meeting. The Shareholders Agreement requires the Issuer to maintain a Nominating and Governance Committee comprised of a majority of independent directors. The Shareholders Agreement provides that the Nominating Committee shall have the exclusive authority to nominate directors other than those designated by Weichai America (pursuant to Weichai America’s rights under the Investor Rights Agreement) for election by the stockholders of the Issuer, but does not otherwise obligate Weichai America or the Founding Stockholders to vote in favor of or against the election of any such nominees. The Shareholders Agreement further provides that unless prohibited by applicable laws or stock exchange requirements, Weichai shall have the right to nominate all of the Weichai directors as non-independent directors.

The Shareholders Agreement contains a right of first refusal which obligates the Founding Stockholders prior to the transfer of any shares of Common Stock (or other equity securities of the Issuer), other than to certain prescribed permitted transferees and certain excepted transfers, to first offer to sell such securities to Weichai America in accordance with the procedures set forth in the agreement.

Stock Pledge Agreement

On March 31, 2017, the Founding Shareholders and Weichai America entered into the Stock Pledge Agreement pursuant to which the Founding Stockholders have pledged an aggregate of 4,180,545 shares of Common Stock beneficially owned by them in favor of Weichai America to secure the obligations of the Issuer to obtain stockholder approval of the Stockholder Proposals (whether by Written Consent or otherwise) on or before the first anniversary of the Closing Date. Under the Stock Pledge Agreement, Weichai America will either (A) obtain record ownership of such pledged shares of Common Stock and the voting power of additional 590,703 shares of Common Stock held by Founding Stockholders or (B) the voting power associated with such pledged shares of Common Stock effective, in each case if the Stockholder Proposals are not approved by the Issuer’s stockholders within one year following the Closing Date. The Stock Pledge Agreement, and the pledge by the Founding Stockholders of the shares of Common Stock thereunder, shall terminate upon the Shareholder Approval Date and the conversion of the Series B Preferred Stock into Common Stock.

Strategic Collaboration Agreement

In connection with the transactions contemplated under the Purchase Agreement, on March 20, 2017, the Issuer and Weichai Power entered into the Collaboration Agreement. Among other things, the Collaboration Agreement establishes a joint steering committee, permits Weichai Power to second a limited number of technical, marketing, sales, procurement and financing personnel to work with the Issuer and establishes the parameters for several collaboration projects, including with respect to Stationary National Gas Application and Weichai Diesel Engines. The Collaboration Agreement provides for the joint steering committee to create various sub-committees with operating roles and otherwise specifies the treatment of intellectual property of parties prior to the collaboration and the intellectual property developed in the collaboration. The Collaboration Agreement has a term of three years.

(b)    In furtherance and not in limitation of the foregoing, following the Closing, in the event that the conversion of the Company Preferred Stock to Company Common Stock or the exercise of the Warrants by the Purchaser would require a filing under the HSR Act, then, the Purchaser, on the one hand, and the Company, on the other hand, shall (i) make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby as required by the HSR Act as promptly as practicable following such determination, (ii) supply as promptly as practicable any additional information and documentary material that may be requested pursuant to the HSR Act and (iii) use its reasonable best efforts to take all other actions necessary to cause the expiration or termination of the applicable waiting periods under the HSR Act as soon as practicable; provided, that nothing herein shall prohibit the Purchaser or the Company from, in good faith, seeking to limit the scope or content of any such request.

27

(f)    For the purposes of this Section 4.01, “reasonable best efforts” shall be deemed to include, subject to the proviso below, complying with any requirements of applicable Law or order of any Governmental Authority that may be imposed in connection with seeking and obtaining any consents, approvals, authorizations, waivers or exemptions of any Governmental Authority necessary to consummate the transactions contemplated by this Agreement; provided, that, for the purposes of this Section 4.01, “reasonable best efforts” shall not require, or be deemed to require either party or any of its Affiliates to agree to or take any action that would result in any arrangements, conditions or restrictions imposed by any Governmental Authority that would, individually or in the aggregate, reasonably be expected to have (A) a material adverse effect on the anticipated economic benefit or value that such party reasonably expects to be realized from the transactions contemplated under this Agreement or the other Transaction Documents or (B) a material adverse effect on the businesses of such party and its Subsidiaries and Affiliates, taken as a whole.

(g)    Notwithstanding anything to the contrary herein or in any of the other Transaction Documents (including the Warrants), if the conversion of the Company Preferred Stock or Company Common Stock or the exercise of the Warrants by the Purchaser following Closing would result in the requirement for any material approval of a Governmental Authority to be obtained, the Company shall use reasonable best efforts to promptly obtain such approval of such Governmental Authority so that the conversion of the Company Preferred Stock or Company Common Stock or the exercise of the Warrants by the Purchaser can be completed without delay.

Except as expressly set forth in Schedule 4.02, between the date of this Agreement and the Closing, the Company and its Subsidiaries shall operate their respective businesses only in the ordinary course consistent with past practice. Without limiting the generality of the foregoing, except as expressly set forth in Schedule 4.02, from the date hereof until the date of the Closing, other than as contemplated by this Agreement or any other Transaction Documents, the Company shall not, and shall cause each of its Subsidiaries not to, without the Purchaser’s prior written consent, take any action that, if taken prior to the date hereof, would constitute a breach or violation of clauses (i) through (xii) of Section 3.01(i).

Section 4.03.    Access to Information; Confidentiality.

(a)    Subject to compliance with applicable Laws, the Company shall, and shall cause each of its Subsidiaries to, afford to the Purchaser and its representatives reasonable access upon reasonable advance notice and during normal business hours during the period prior to the Closing or the termination of this Agreement to all their respective properties, assets, books, records, Contracts, permits, documents, information, directors and officers, and during such period the Company shall, and shall cause each of its Subsidiaries to, make available to the Purchaser any information concerning its business as the Purchaser may reasonably request. For the avoidance of doubt, the foregoing provision shall not be deemed to provide the Purchaser the right to contact the Company’s customers or vendors alone without the Company’s prior written consent, which shall not be unreasonably withheld or delayed.

(b)    No investigation by the Purchaser or any of its representatives and no other receipt of information by the Purchaser or any of its representatives shall operate as a waiver or otherwise affect any representation, warranty, covenant, agreement or other provision of this Agreement, or the obligations of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under the Agreement.

(c)    The terms of the Confidentiality Agreement are hereby incorporated herein by reference and shall continue in full force and effect until the Closing. Nothing provided to the Purchaser pursuant to this Section 4.03 shall in any way amend or diminish the Purchaser’s obligations under the Confidentiality Agreement. The Purchaser acknowledges and agrees that any Confidential Information (as defined in the Confidentiality Agreement) provided to the Purchaser pursuant to this Section 4.03 or otherwise by or on behalf of the Company or any representative thereof shall be subject to the terms and conditions of the Confidentiality Agreement. If this Agreement is, for any reason, terminated prior to the Closing, the Confidentiality Agreement and the obligations of the Purchaser thereunder shall nonetheless continue in full force and effect.

Section 4.04.    Notification of Certain Matters. The Company shall give prompt notice to the Purchaser, and the Purchaser shall give prompt notice to the Company, of the occurrence, or non-occurrence, of any event the occurrence or non-occurrence of which would

In the event that the Company issues or agrees to issue shares of Company Common Stock or any other Securities pursuant to or in connection with the PPPI Purchase Agreement (including the settlement of any Action relating thereto) at any time after the eighteen (18) month anniversary of the Closing, the Company shall promptly issue to the Purchaser the Additional Warrant.

Section 4.08.    Securities Laws; Legends.

(a)    The Purchaser acknowledges and agrees that the Securities have not been registered under the Securities Act or the securities laws of any state and that they may be sold or otherwise disposed of only in one or more transactions registered under the Securities Act and, where applicable, such laws, or as to which an exemption from the registration requirements of the Securities Act and, where applicable, such laws, is available. The Purchaser acknowledges that, except as provided in the Investor Rights Agreement, the Purchaser has no right to require the Company to register the Securities. The Purchaser further acknowledges and agrees that any certificate or evidence of book-entry notation for the Securities shall bear a legend substantially as set forth in paragraph (b) of this Section 4.08 (and any shares evidenced in book entry form shall contain appropriate comparable notation and reflect related stop transfer instructions).

(b)    Any certificates for the Securities shall bear a legend in substantially the following form:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO A

30

REGISTRATION STATEMENT IN EFFECT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT OR SUCH LAWS.

(c)    When issued pursuant hereto, the certificates evidencing the Securities shall also bear any legend required by any applicable state blue sky law.

(d)    Any holder of Securities may request the Company to remove any or all of the legends described in this Section 4.08 from the certificates evidencing such Securities by submitting to the Company such certificates, and, in the case of the legend relating to restrictions on transfer under the Securities Act or applicable state laws, together with an opinion of counsel, to the effect that such legend or legends are no longer required under the Securities Act or applicable state laws, as the case may be. Following the first anniversary of the Closing Date, the Company shall, if requested, promptly remove the restrictive legend relating to restrictions on transfer in this Agreement from any certificates representing the Purchaser’s Securities.

Section 4.09.    Lost, Stolen, Destroyed or Mutilated Securities. Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of any certificate for any security of the Company and, in the case of loss, theft or destruction, upon delivery of an undertaking by the holder thereof to indemnify the Company (and, if requested by the Company, the delivery of an indemnity bond sufficient in the reasonable judgment of the Company to protect the Company from any loss it may suffer if a certificate is replaced), or, in the case of mutilation, upon surrender and cancellation thereof, the Company will issue a new certificate or, at the Company’s option, a share ownership statement representing Securities for an equivalent number of shares or another security of like tenor, as the case may be.

Section 4.10.    Stockholder Approval. Immediately after the execution of this Agreement and in lieu of calling a stockholders meeting, the Company shall use its reasonable best efforts to deliver to the Purchaser an irrevocable stockholder written consent (the “Stockholder Written Consent”) executed by the Founder Stockholders (who will then collectively hold a majority of the Company’s issued and outstanding Company Common Stock) adopting resolutions to approve: (i) the conversion of the Company Preferred Stock to the Company Common Stock; (ii) issuance of Company Common Stock upon exercise of the Warrants; and (iii) the proxy, board representation and voting rights set forth in the Shareholder Agreement and Investor Rights Agreement (collectively, the “Stockholder Proposal”). The Company represents that the Stockholder Written Consent shall be sufficient to approve the Stockholder Proposal without requiring any additional written consent from other stockholders or convening any stockholders meeting to vote on the Stockholder Proposal pursuant to the applicable Law, certificate of incorporation and/or bylaws of the Company. If such Stockholder Written Consent is not delivered to the Purchaser within one (1) calendar day following the execution of this Agreement, Purchaser shall have the right to terminate this Agreement pursuant to Section 6.01(b) herein. The Company shall, in accordance with applicable Law, mail to any stockholder of the Company that did not execute the Stockholder Written Consent approving the transactions contemplated hereby, notice of such Stockholder Written Consent as required by

31

Section 228 of the Delaware Corporation Law. The Company shall promptly prepare (and the Purchaser will reasonably cooperate with the Company to prepare) and file (but in no event more than sixty (60) days following the Closing) with the SEC a preliminary information statement relating to the Stockholder Written Consent, shall respond to any comments of the SEC or its staff to as promptly as practicable for the purpose of clearing the Company’s information statement with the SEC in accordance with applicable Law and satisfaction of any other regulatory requirements, and cause a definitive information statement related to such Stockholder Written Consent to be mailed to the Company’s stockholders as promptly as practicable after clearance by the SEC. The Company agrees that each information statement referred to in this Section 4.10, when mailed to the Company’s stockholders, shall comply as to form in all material respects with the requirements of the Exchange Act and the rules and regulations promulgated thereunder and that none of the information included or incorporated by reference in any such information statement will, at the date it is mailed to the stockholders of the Company, or at the time of any amendment or supplement thereof, to the best of Company’s knowledge contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading, except for statements made in such information statement based exclusively on information supplied in writing by or on behalf of the Purchaser specifically and explicitly for inclusion or incorporation by reference therein. The Purchaser and the Company agree promptly to correct any information provided by it or on its behalf for use in the information statement if and to the extent that such information shall have become false or misleading in any material respect, and the Company shall as promptly as practicable prepare and mail to its stockholders an amendment or supplement to correct such information to the extent required by applicable laws and regulations. The Company shall consult with the Purchaser prior to mailing any such information statement, or any amendment or supplement thereto, and provide the Purchaser with a reasonable opportunity to comment thereon. The Company shall promptly notify the Purchaser upon the receipt of any comments from the SEC or its staff or any request from the SEC or its staff for amendments or supplements to any information statement and shall provide the Purchaser with copies of all correspondence between it and its representatives, on the one hand, and the SEC, on the other hand. The Stockholder Written Consent shall become effective twenty (20) calendar days following the distribution of such information statement to the Company’s stockholders (the “Stockholder Approval”), and the Company shall ensure that the Stockholder Approval is obtained within one hundred eighty (180) days following Closing. In the event that the Company is unable to obtain, as a matter of Law, the approval of the transactions contemplated under this Agreement by Company stockholders through the Stockholder Written Consent and the mailing of the information statement to Company stockholders as contemplated under the provisions in this Section 4.10 above within one hundred eighty (180) days following Closing, at the request of the Purchaser, the Company shall immediately call and hold a meeting of its stockholders and include a proposal to approve (and, the Board of Directors shall recommend approval of) the Stockholder Proposal at its stockholders meeting no less than once in each three (3)-month period beginning on the one hundred eightieth (180) days following Closing until stockholders approve Stockholder Proposal in its entirety.

Section 4.11.    Listing. The Company shall, following the Closing Date, use reasonable best efforts to effect the listing of the Purchased Common Shares and Company Common Stock issuable upon conversion of the Purchased Preferred Shares and the exercise of the Warrants on Nasdaq.

32

Section 4.12.    Reservation of Shares. From and after the Closing, the Company shall at all times reserve and keep available out of its authorized but unissued shares of Company Common Stock, solely for the purpose of providing for the conversion of the Purchased Preferred Shares and the exercise of the Warrants, such number of shares of Company Common Stock as shall from time to time equal the number of shares sufficient to permit the conversion of the shares of Purchased Preferred Shares and the exercise of the Warrants issued pursuant to this Agreement in accordance with their respective terms. The Company covenants that all shares of Company Common Stock issuable upon conversion of the Purchased Preferred Shares and the exercise of the Warrants shall, upon such issue, be duly and validly issued and fully paid and non-assessable. If at any time the number of authorized but unissued shares of Company Common Stock shall not be sufficient to effect the conversion of the Purchased Preferred Shares and the exercise of the Warrants or otherwise to comply with the terms of this Agreement, the Company shall take all corporate action as may be necessary to increase its authorized but unissued shares of Company Common Stock to such number of shares as shall be sufficient for such purposes. The Company will use its reasonable best efforts to obtain any authorization, consent, approval or other action by, and shall make any filing with any court or administrative body that may be required under, applicable state securities laws in connection with the issuance of shares of Company Common Stock upon conversion of the Purchased Preferred Shares and the exercise of the Warrants.

Section 4.13.    Third Party Consents.

(a)    The Company shall, and shall cause its Subsidiaries to, use their respective reasonable best efforts to obtain all necessary consents required to be obtained, and to make all necessary notices required to be made, by it from third parties (other than Governmental Authorities) to avoid the breach or termination of any Contract to which the Company or any of its Subsidiaries are party and, by its terms, requires the notice to or consent of such third party or provides such third party any termination rights in connection with the transactions contemplated by this Agreement and the other Transaction Documents, including certain specific consents of counterparties to those Contracts set forth on Section 4.13 of the Company Disclosure Schedule (such specific consents, the “Required Third Party Consents”) which shall be obtained prior to Closing, unless the Company and the Purchaser mutually agree that any consents are not desired. The Company shall consult with and keep the Purchaser reasonably informed on a reasonably current basis of the status of the Required Third Party Consents, including promptly providing any material communications to or from any third parties in connection with the procurement of the Required Third Party Consents

(b)    The Company and the Purchaser agree that, in the event that any consent, approval or authorization necessary to preserve for the Company or any of its Subsidiaries any right or benefit under any Contract to which the Company or any of its Subsidiaries is a party is not obtained prior to the Closing, the parties hereto will use their commercially reasonable efforts to obtain such consent, approval or authorization as promptly thereafter as reasonably practicable.

33

Section 4.14.    Stock Pledge Agreement. The Purchaser agrees to, and the Company shall cause the Founder Stockholders to, enter into definitive documentation with each other prior to or concurrently with the Closing, negotiated in good faith with the other Parties, in respect of a Stock Pledge Agreement relating to a pledge by the Founder Stockholders of an aggregate of 4,180,545 shares of Company Common Stock beneficially owned by them on terms consistent in all material respects with those set forth on Exhibit F hereto and, to the extent not inconsistent with the terms set forth on Exhibit F hereto, other customary provisions for agreements of this kind as mutually agreed by the Parties (the “Stock Pledge Agreement”).

Section 4.15.    Key Employee Retention Program. Subject to the approval by the Board of Directors, the Company will prepare a retention program for the key employees of the Company including any equity incentive plan (“Key Employee Retention Program”) which shall be consistent with industry standards and present such Key Employee Retention Program to the Purchaser. The Parties shall discuss in good faith and agree on the Key Employee Retention Program before it is adopted and implemented, the Purchaser shall not unreasonably withhold its consent.

This Agreement, the Company Disclosure Schedules and any other document or instrument delivered pursuant hereto, and all claims or causes of Action (whether in contract or tort) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution, termination, performance or nonperformance of this Agreement (including any claim or cause of Action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement) shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflicts of law rules of such state.

Section 7.06.    Public Announcements. The press release announcing the execution of this Agreement shall be issued only in such form as shall be previously agreed upon by the Purchaser and the Company. Thereafter, at any time prior to Closing or the termination of this Agreement in accordance with ARTICLE VI, the Purchaser and the Company shall consult with each other before issuing any press release scheduling any press conference or conference call with investors or analysts with respect to this Agreement and, except in respect of any such press release, press conference or conference call as may be required by applicable Law or rules and policies of Nasdaq or the rules of any stock exchange on which the securities of the Purchaser or any of its Affiliates are listed, shall not issue any such press release, have any such communication, make any such other public statement or schedule any such press conference or conference call prior to such consultation.

Section 7.07.    Expenses. Except as otherwise provided herein, each party shall pay all costs and expenses that it incurs with respect to the negotiation, execution, delivery and performance of this Agreement.

Section 7.08.    Indemnification.

(a)    From and after the Closing, the Company agrees to indemnify and hold harmless the Purchaser, each person who controls the Purchaser within the meaning of the Exchange Act, and each of the respective officers, directors, employees, agents and Affiliates of the foregoing in their respective capacities as such (the “Purchaser Indemnified Parties”), to the fullest extent lawful, from and against any and all costs, expenses, damages, obligations, liabilities, assessments, judgments, losses (including diminution in value), settlements, awards and fees (including but not limited to any investigative fees, reasonable legal fees and other expenses incurred in connection with, and any amounts paid in settlement of, any pending or threatened Action) (collectively, “Losses”) arising out of or resulting from:

(i)    the failure of any representation or warranty of the Company set forth in this Agreement or any certificate delivered pursuant to this Agreement to be true and correct in all respects as at the date hereof and as of the Closing Date;

(ii)    any breach or non-fulfillment of any covenant or agreement made or to be performed by the Company in this Agreement;

(iii)    any aggregate net reduction in the Company’s and its Subsidiaries’ consolidated net income or consolidated net assets (including accounts receivable) or increases in the Company’s and its Subsidiaries’ consolidated liabilities as reflected on the Company’s and its Subsidiaries’ consolidated financial statements included in the SEC Filings as a result of any financial accounting issue(s) or restatement(s) arising out of or in connection with the Company’s historical accounting practices or internal controls over financial reporting, other than the specific issues or restatements (and amounts thereof) set forth in the Identified Matters, and other than shifts of consolidated net income, consolidated net assets or consolidated liabilities from one period to another period or periods (including periods subsequent to the periods included in the SEC Filings); and

(iv)    any Action, including any Action or investigation by any third party (including any Governmental Authority), and any liability to any third party (including any Governmental Authority) in defense, settlement or judgment in respect of any such Action, arising out of or in connection with the Identified Matters or any other facts, issues or circumstances relating to the Company’s historical accounting practices, internal controls over financial reporting and financial accounting restatement(s) or allegations of misstatements or omissions in any SEC Filings relating thereto.

40

(b)    From and after the Closing, the Purchaser agrees to indemnify and hold harmless the Company, each person who controls the Company within the meaning of the Exchange Act, and each of the respective officers, directors, employees, agents and Affiliates of the foregoing in their respective capacities as such, to the fullest extent lawful, from and against any and all Losses arising out of or resulting from any misrepresentation or breach of any representation or warranty made by the Purchaser in this Agreement or any breach or non-fulfillment of any covenant or agreement made or to be performed by the Purchaser in this Agreement.

(c)    Notwithstanding anything to the contrary contained in this Agreement, the Company shall not be liable for any claim to any Purchaser Indemnified Party pursuant to Section 7.08(a)(iv) unless and until the aggregate amount of indemnifiable Losses which may be recovered equals or exceeds $5,000,000, after which the Company shall only be liable to the Purchaser Indemnified Parties for those Losses in excess of $5,000,000.

(d)    The party making a claim of indemnification under this Section 7.08 (the “Indemnified Party”) shall give written notice to the party against whom such claim is asserted (the “Indemnifying Party”) promptly after the discovery by such party of any matters giving rise to a claim for indemnification; provided that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 7.08 unless and to the extent that the Indemnifying Party shall have been actually prejudiced by the failure of such Indemnified Party to so notify such party. In case any such action, suit, claim or proceeding is brought against an Indemnified Party, the Indemnified Party shall be entitled to hire, at its own expense, separate counsel and participate in the defense thereof; provided, however, that the Indemnifying Party shall be entitled to assume and conduct the defense, unless (i) the Indemnifying Party shall have failed to assume the defense of such claim within a reasonable time after receipt of notice of such claim from the Indemnified Party, (ii) the Indemnified Party has reasonably concluded (based upon advice of its counsel) that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Party, or (iii) in the reasonable judgment of any Indemnified Party (based upon advice of its counsel) a conflict of interest may exist between the Indemnified Party and the Indemnifying Party with respect to such claims, then, in each case, the Indemnified Party may assume responsibility for conducting the defense (in which case the Indemnifying Party shall be liable for any reasonable legal or other expenses reasonably incurred by the Indemnified Party in connection with assuming and conducting the defense). No Indemnifying Party shall be liable for any settlement of any action, suit, claim or proceeding effected without its written consent; provided, however, the Indemnifying Party shall not unreasonably withhold its consent. The Indemnifying Party further agrees that it will not, without the Indemnified Party’s prior written consent, settle or compromise any claim or consent to entry of any judgment in respect thereof in any pending or threatened action, suit,

41

claim or proceeding in respect of which indemnification could reasonably be expected to be available hereunder (whether or not any Indemnified Party is an actual or potential party to such action, suit, claim or proceeding) unless such settlement or compromise includes an unconditional release of each Indemnified Party from all liability arising out of such action, suit, claim or proceeding. If written notice of a bona fide claim for indemnification under Section 7.08 has been given in respect of any breach of the representations or warranties made by a party in this Agreement prior to the expiration of the applicable representation or warranty, then the obligation to indemnify in respect of such breach shall survive as to such claim, until such claim has been finally resolved.

(e)    Notwithstanding anything to the contrary contained in this Agreement, after the Closing, none of the parties hereto and none of their respective Affiliates shall have any liability under any provision of this Agreement for any (i) special, speculative, indirect or consequential Loss or lost profits (including loss of future revenue or income, loss of business reputation or opportunity relating to the breach or alleged breach of this Agreement, or damages based on any type of multiple of earnings or similar basis) or (ii) punitive damages, except, in each case, any such indemnifiable Losses that are recovered by a third party in connection with a third-party claim or resulting from a Governmental Order.

(f)    For all purposes of this Section 7.08, “Losses” shall be net of (i) payments actually paid to the Indemnified Party under any insurance policy with respect to such Losses, and (ii) any prior or subsequent actual recovery by the Indemnified Party from any third party Claim with respect to such Losses, in either case net of any fees or expenses incurred in obtaining such recovery, including any increase in premiums resulting from such claim. Each Indemnifying Party shall use reasonable best efforts to collect any amounts available under applicable insurance policies, or from any other Person alleged to be responsible, for any Losses payable under this Section 7.08; provided that in no event shall this Section 7.08 require any party to institute an Action against any Person.

(g)    The Indemnified Parties shall be entitled to only a single recovery (without duplication) for indemnified Losses that arise in connection with each matter giving rise to a breach of representation, warranty or covenant, even if such matter shall involve breaches of multiple representations, warranties and covenants.

(h)    For the avoidance of doubt, the Identified Matters shall be deemed to qualify all of the Company’s representations and warranties set forth in Article III herein.

(i)    For the avoidance of doubt, in calculating any Losses suffered by the Purchaser Indemnifying Parties due to the Losses suffered by the Company or the obligation of the Company to pay any monetary damages to any third party (including any Governmental Authority) (including any Losses of the types described in Sections 7(a)(iii) or 7(a)(iv) (other than, with respect to Section 7(a)(iv), Losses

42

suffered directly by the Purchaser Indemnified Parties), the calculation for the amount to be indemnified by the Company to the Purchaser Indemnified Parties shall be (x) the total Losses and monetary damages suffered by the Company, multiplied by (y) the Purchaser’s percentage ownership of the Company Common Stock (on a fully-diluted as-converted basis) as of the Closing, assuming for the purposes of such calculation the conversion of the Purchased Preferred Shares into Company Common Stock as of such time but excluding for purposes of such calculation all Company Common Stock or Company Preferred Stock issuable upon exercise of the Warrants; and with respect to Losses actually suffered directly by the Purchaser Indemnified Parties under this Agreement, the amount to be indemnified by the Company to the Purchaser Indemnified Parties shall be the entire amount of such Losses irrespective of Purchaser’s percentage ownership of the Company Common Stock.

(j)    The obligations of the Indemnifying Party under this Section 7.08 shall survive the transfer of the Securities. The agreements contained in this Section 7.08 shall be in addition to any other rights of the Indemnified Party against the Indemnifying Party or others, at common law or otherwise, including for actual fraud involving a knowing and intentional misrepresentation of a fact material to the transactions contemplated by this Agreement made with the intent of inducing any other party hereto to enter into this Agreement and upon which such other party has relied (as opposed to any fraud claim based on constructive knowledge, negligent misrepresentation or a similar theory) under applicable tort laws.

(k)    Notwithstanding anything in this Agreement to the contrary, the Purchaser may, at its sole discretion and without prejudice to any other rights it may have, deduct, set off and net all or a portion of indemnified Losses finally determined to be owed by the Company to the Purchaser Indemnified Parties pursuant to this Section 7.08 against the equivalent amount payable by the Purchaser to the Company under this Agreement or any other Transaction Documents, including without limitation the exercise price of the 2018 Warrant. Neither the exercise of nor the failure to exercise of such right of set off by the Purchaser will limit the Purchaser in any manner in the enforcement of any other remedies that may be available to it in connection with this Agreement under applicable Law.

Section 7.09.    Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the Company’s successors and assigns and the Purchaser’s successors and assigns, and no other person. Neither party may assign its rights or obligations hereunder without the prior written consent of the other party, which consent shall not be unreasonably withheld or delayed; provided, however, that (i) that the Purchaser may assign its rights under this Agreement to one or more of its Affiliates and (ii) the Company shall have the right to collaterally assign its rights under this Agreement to any party that provides financing to the Company, provided, however, that if such collateral assignment would adversely affect the Purchaser in any manner, such collateral assignment shall require the prior written consent from the Purchaser. No assignment shall relieve the assigning party of any of its obligations hereunder.

43

Section 7.10.    Arbitration.

(a)    Any and all disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision) shall be referred to and finally resolved by arbitration under the Rules of Arbitration of the London Court of International Arbitration (“LCIA Rules”) by one or more arbitrators appointed in accordance with the LCIA Rules (the “Arbitral Tribunal”).

(b)    The arbitration shall be conducted by a sole arbitrator unless either party objects, in which case the arbitration shall be conducted by a panel of three arbitrators. Where the arbitration is to be conducted by a sole arbitrator, the parties shall attempt to agree upon the selection of the sole arbitrator. If they cannot reach agreement within 30 days from the commencement of the arbitration, the sole arbitrator shall be appointed by the Court of the LCIA (the “LCIA Court”) in accordance with the LCIA Rules. Where the arbitration is to be conducted by a panel of three arbitrators, each party shall nominate one arbitrator and the two party-nominated arbitrators shall then select the chairman of the Arbitral Tribunal. If the two party-nominated arbitrators are unable to do so within 30 days after the commencement of the arbitration or any mutually agreed extension thereof, the chairman shall be selected by the LCIA Court in accordance with the LCIA Rules.

(c)    The place of arbitration shall be London.

(d)    The language of the arbitration shall be English.

(e)    Each arbitrator shall be licensed to practice law in New York.

(f)    Each party shall have the right to apply to any court of competent jurisdiction and/or to the Arbitral Tribunal for an order or award of temporary or preliminary injunctive relief or other measures of interim, provisional or conservatory measures in order to maintain the status quo or to protect its rights or property pending arbitration pursuant to this Agreement or for the purpose of compelling a party to arbitrate and seeking temporary or preliminary injunctive relief in aid of an arbitration hereunder, and any such application shall not be deemed incompatible with, or a waiver of, the parties’ agreement to arbitrate.

(g)    The Arbitral Tribunal shall have power to take whatever interim measures it deems necessary, including injunctive relief, specific performance and other equitable relief, including in accordance with the provisions set forth in Section 7.14 of this Agreement.

(h)    The award rendered by the Arbitral Tribunal shall be final and binding between the parties and not subject to appeal or other recourse.

(i)    Recognition and enforcement of any award rendered by the Arbitral Tribunal may be sought in any court of competent jurisdiction. Disclosure Schedule References.

44

Section 7.11.    Disclosure Schedule References(a) . The Parties agree that any reference in a particular Section of the Company Disclosure Schedule shall only be deemed to be an exception to (or, as applicable, a disclosure for purposes of) (a) the representations and warranties (or covenants, as applicable) of the Company that are contained in the corresponding Section of this Agreement and (b) any other representations and warranties of the Company that is contained in this Agreement, but only if the relevance of that reference as an exception to (or a disclosure for purposes of) such representations and warranties would be readily apparent to a reasonable person who has read that reference and such representations and warranties, without any prior knowledge on the part of the reader regarding the matter(s) so disclosed. The inclusion of an item in the Company Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission that such item represents a material exception or material fact, event or circumstance or that such item would reasonably be expected to, individually or in the aggregate, prevent, materially delay or materially impede the ability of the Company to consummate the transactions contemplated by this Agreement.

Section 7.12.    Severability. If any provision of this Agreement is determined to be invalid, illegal, or unenforceable, the remaining provisions of this Agreement shall remain in full force and effect provided that the economic and legal substance of, any of the Transactions is not affected in any manner materially adverse to any party. In the event of any such determination, the parties agree to negotiate in good faith to modify this Agreement to fulfill as closely as possible the original intent and purpose hereof. To the extent permitted by law, the parties hereby to the same extent waive any provision of law that renders any provision hereof prohibited or unenforceable in any respect.

Section 7.13.    Specific Performance; Remedies. Each Party agrees that (i) irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the other Party does not perform the provisions of this Agreement (including failing to take such actions as are required of them hereunder in order to consummate the transactions contemplated by this Agreement) in accordance with its specified terms or otherwise breach such provisions and (ii) the right of such Party to specific enforcement is an integral part of the transactions contemplated by this Agreement and without that right, such Party would not have entered into this Agreement. Each Party acknowledges and agrees that the other Party shall be entitled to seek an injunction, specific performance and other equitable relief to prevent breaches of this Agreement by the other Party and to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which such Party is entitled at law or in equity. Each Party agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that (x) the other Party has an adequate remedy at law or (y) an award of specific performance is not an appropriate remedy for any reason at law or equity. If a Party seeks an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, it shall not be required to provide any bond or other security in connection with any such order or injunction.

Section 7.14.    Cumulative Remedies. Except as otherwise expressly provided herein, any and all remedies provided herein will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

CERTIFICATE OF DESIGNATION OF

SERIES B CONVERTIBLE PERPETUAL PREFERRED STOCK OF

POWER SOLUTIONS INTERNATIONAL, INC.

Pursuant to Section 151 of the

General Corporation Law of the State of Delaware

Power Solutions International, Inc., a Delaware corporation (the “Company”), certifies that pursuant to the authority contained in its Amended and Restated Certificate of Incorporation (as amended, the “Certificate of Incorporation”), and in accordance with the provisions of Section 151 of the General Corporation Law of the State of Delaware (the “DGCL”), the Board of Directors of the Company (the “Board of Directors”), on March     , 2017, duly approved and adopted the following resolution, which resolution remains in full force and effect on the date hereof:

RESOLVED, that pursuant to the authority vested in the Board of Directors by the Certificate of Incorporation, the Board of Directors does hereby designate, create, authorize and provide for the issue of a series of the Company’s preferred stock, par value $0.001 per share, with a liquidation preference (as further set out in Section 3) of $16.00 per share (the “Liquidation Preference”), which shall be designated as Series B Convertible Perpetual Preferred Stock (the “Series B Preferred Stock”), consisting of 2,385,624 shares, no shares of which have heretofore been issued by the Company, having the following powers, designations, preferences and relative, participating, optional and other special rights, and qualifications, limitations and restrictions thereof:

Certain defined terms used in this Certificate of Designation have the meanings assigned thereto in Section 14.

Section 1.    Ranking. The Series B Preferred Stock shall rank, with respect to payment of dividends and distribution of assets upon the liquidation, winding-up or dissolution of the Company, (a) senior to the common stock, par value $0.001 per share, of the Company (the “Common Stock”), whether now outstanding or hereafter issued, and to each other class or series of stock of the Company (including any series of preferred stock established after March     , 2017 (the “Issue Date”) by the Board of Directors) the terms of which do not expressly provide that such class or series ranks senior to, or pari passu, with the Series B Preferred Stock as to payment of dividends and distribution of assets upon the liquidation, winding-up or dissolution of the Company (collectively referred to as “Junior Stock”); (b) pari passu with each other class or series of stock of the Company (including any series of preferred stock established after the Issue Date by the Board of Directors) the terms of which expressly provide that such class or series ranks pari passu with the Series B Preferred Stock as to payment of dividends and distribution of assets upon the liquidation, winding-up or dissolution of the Company (collectively referred to as “Parity Stock”); and (c) junior to each other class or series of stock of the Company (including any series of preferred stock established after the Issue Date by the Board of Directors) the terms of which expressly provide that such class or series ranks senior to the Series B Preferred Stock as to payment of dividends and distribution of assets upon

the liquidation, winding-up or dissolution of the Company (collectively referred to as “Senior Stock”). The Company’s ability to issue Capital Stock that ranks pari passu with or senior to the Series B Preferred Stock shall be subject to the provisions of Section 4.

Section 2.    Dividends.

(a)    Prior to the Dividend Accrual Date. Prior to the Dividend Accrual Date, Holders of shares of Series B Preferred Stock shall be entitled to participate equally and ratably with the holders of shares of Common Stock in all dividends on the shares of Common Stock as if immediately prior to each record date for the Common Stock, shares of Series B Preferred Stock then outstanding were converted into shares of Common Stock in accordance with the terms hereof. Dividends payable pursuant to this Section 2(a) shall be payable on the same date that such dividends are payable to holders of shares of Common Stock, and no dividends shall be payable to holders of shares of Common Stock unless dividends contemplated by this Section 2(a) are also paid at the same time in respect of the Series B Preferred Stock on a pro rata basis. Each dividend shall be payable to the holders of record of shares of Series B Preferred Stock as they appear on the stock records of the Company at the close of business on the same day as the record date for the payment of dividends to the holders of shares of Common Stock.

(b)    Following the Dividend Accrual Date. Commencing on and following the Dividend Accrual Date, Holders of shares of Series B Preferred Stock shall be entitled to cumulative dividends on the Series B Preferred Stock payable quarterly, which dividend shall be declared by the Board of Directors or a duly authorized committee thereof, out of the assets of the Company legally available therefor, and thereafter, if so declared, be payable on the 15th calendar day (or the following Business Day if the 15th is not a Business Day) of January, April, July and October of each year (each such date being referred to herein as a “Dividend Payment Date”) (the period between each such Dividend Payment Date, a “Dividend Period”) at the rate per annum of 10% per share on the Liquidation Preference; provided that, in the event that on any Dividend Payment Date, the Company is not permitted to declare or pay such dividend or incur such liability either (x) as a matter of law or (y) under the terms of the Company’s debt financing agreements, such dividend (a “Deferred Dividend”) shall not be declared by the Board of Directors, shall not be paid or payable on such Dividend Payment Date and no liability shall be incurred in respect thereof, and instead, such Deferred Dividend shall be declared, become payable and be paid and the liability in respect thereof be incurred on the first succeeding Dividend Payment Date on which the Company is not prohibited from declaring, paying and incurring the liability in respect of such Deferred Dividend (and, for the avoidance of doubt, such Deferred Dividend shall be payable in addition to, and not in lieu of, any dividend which would ordinarily be payable on such succeeding Dividend Payment Date). The amount of dividends payable for any other period that is shorter or longer than a full quarterly dividend period will be computed on the basis of a 360-day year consisting of twelve 30-day months.

For purposes of this Section 2(b), a dividend period with respect to a Dividend Payment Date is the period commencing on the preceding Dividend Payment Date (or, if there is no preceding Dividend Payment Date, the Dividend Accrual Date) and ending on the day immediately prior to the next Dividend Payment Date. Dividends payable on a Dividend Payment Date shall be payable to Holders of record on the later of (i) the close of business on the first calendar day (or the following Business Day if such first calendar day is not a Business

2

Day) of the calendar month in which the applicable Dividend Payment Date falls and (ii) the close of business on the day on which the Board of Directors or a duly authorized committee thereof declares the dividend payable (each, a “Dividend Record Date”).

(c)    Payment of Dividends. Notwithstanding anything to the contrary herein, the Company shall make each dividend payment on the Series B Preferred Stock in cash (or, if applicable, in the same form as such dividend is paid to holders of Common Stock). Each fractional share of Series B Preferred Stock outstanding shall be entitled to a ratably proportionate amount of all dividends accumulating with respect to each outstanding share of Series B Preferred Stock pursuant to Section 2, and all such dividends with respect to such outstanding fractional shares shall accumulate (whether or not declared) and shall be payable in the same manner and at such times as provided for in Section 2 with respect to dividends on each outstanding share of Series B Preferred Stock. Interest at a rate of 10% per annum shall be payable in respect of any Deferred Dividend.

(d)    Payment Restrictions. No dividends or other distributions (other than a dividend or distribution payable solely in shares of Parity Stock or Junior Stock (in the case of Parity Stock) or Junior Stock (in the case of Junior Stock) and other than cash paid in lieu of fractional shares) may be declared, made or paid, or set apart for payment upon, any Parity Stock or Junior Stock, nor may any Parity Stock or Junior Stock be redeemed, purchased or otherwise acquired for any consideration (or any money paid to or made available for a sinking fund for the redemption of any Parity Stock or Junior Stock) by or on behalf of the Company (except by conversion into or exchange for shares of Parity Stock or Junior Stock (in the case of Parity Stock) or Junior Stock (in the case of Junior Stock)), unless all accrued and unpaid dividends shall have been or contemporaneously are declared and paid, or are declared and a sum of cash sufficient for the payment thereof is set apart for such payment, on the Series B Preferred Stock and any Parity Stock for all dividend payment periods terminating on or prior to the date of such declaration, payment, redemption, purchase or acquisition. Notwithstanding the foregoing, if full dividends have not been paid on the Series B Preferred Stock and any Parity Stock, dividends may be declared and paid on the Series B Preferred Stock and such Parity Stock so long as the dividends are declared and paid pro rata so that the aggregate amounts of dividends declared per share on, and the amounts of such dividends declared per share on, the Series B Preferred Stock and such Parity Stock will in all cases bear to each other the same ratio that accrued and unpaid dividends per share on the shares of Series B Preferred Stock and such other Parity Stock bear to each other.

Section 3.    Liquidation Preference. In the event of any voluntary or involuntary liquidation, dissolution or winding-up of the Company, each Holder shall be entitled to receive out of the assets of the Company available for distribution to stockholders of the Company, before any distribution of assets is made on the Common Stock or any other Junior Stock, an amount equal to the greater of (i) the aggregate Liquidation Preference attributable to shares of Series B Preferred Stock held by such Holder plus an amount equal to the sum of all accrued and unpaid dividends for the then-current dividend period, and (ii) the product of (x) the amount per share that would have been payable upon such liquidation, dissolution or winding-up to the holders of shares of Common Stock or such other class or series of securities into which the Series B Preferred Stock is then convertible (assuming the conversion of each share of Series B Preferred Stock), multiplied by (y) the number of shares of Common Stock or such other securities into which the shares of Series B Preferred Stock held by such Holder are then convertible.

3

For the purposes of the immediately preceding paragraph, (i) the sale of all or substantially all of the property or business of the Company, (ii) the merger, conversion or consolidation of the Company into or with any other Person or (iii) the merger, conversion or consolidation of any other Person into or with the Company, shall constitute a voluntary or involuntary liquidation, dissolution or winding-up of the Company.

In the event the assets of the Company available for distribution to Holders upon any liquidation, winding-up or dissolution of the Company, whether voluntary or involuntary, shall be insufficient to pay in full all amounts to which such Holders are entitled pursuant to this Section 3, no such distribution shall be made on account of any shares of Parity Stock upon such liquidation, dissolution or winding-up unless proportionate distributable amounts shall be paid on account of the shares of Series B Preferred Stock, ratably, in proportion to the full distributable amounts for which Holders and holders of any Parity Stock are entitled upon such liquidation, winding-up or dissolution, with the amount allocable to each series of such stock determined on a pro rata basis of the aggregate liquidation preference of the outstanding shares of each series and accrued and unpaid dividends to which each series is entitled.

Section 4.    Voting Rights. (a) The Holders of shares of Series B Preferred Stock will not have any voting rights, including the right to elect any directors, except (i) voting rights, if any, required by law, and (ii) voting rights, if any, described in this Section 4.

(a)    So long as any Series B Preferred Stock is outstanding, in addition to any other vote of stockholders of the Company required under applicable law or the Certificate of Incorporation, the affirmative vote or consent of the Holders of at least a majority of the outstanding shares of Series B Preferred Stock, voting separately as a single class, will be required (i) for any amendment of the Certificate of Incorporation if the amendment would alter or change the powers, preferences, privileges or rights of the Holders with respect to the Series B Preferred Stock so as to affect them adversely, (ii) to issue, authorize or increase the authorized amount of, or issue or authorize any obligation or security convertible into or evidencing a right to purchase, any Parity Stock or Senior Stock, or (iii) to reclassify any authorized stock of the Company into any Parity Stock or Senior Stock, or any obligation or security convertible into or evidencing a right to purchase any Senior Stock.

Section 5.    Conversion.

(a)    Mandatory Conversion. Effective as of the close of business on the Stockholder Approval Date, with respect to the shares of Series B Preferred Stock of a Holder, such Holder’s shares of Series B Preferred Stock shall automatically, without any action of such Holder, convert into a number of shares of Common Stock equal to the aggregate Liquidation Preference of such shares of Series B Preferred Stock divided by the Conversion Price then in effect (such quotient, the “Conversion Shares”). Upon conversion, Holder shall become the largest stockholder of the Company (assuming it has not transferred any shares of Common Stock it acquired under the Stock Purchase Agreement).

4

(b)    In addition, effective as of the close of business on the Stockholder Approval Date, to the extent that the Company has deferred the payment of cash dividends on the Series B Preferred Stock pursuant to Section 2(b) herein, such unpaid Deferred Dividends shall be cancelled and null.

No Holder may convert shares of Series B Preferred Stock to Common Stock other than pursuant to Section 5(a).

(c)    Conversion Procedures.

(i)    In the event of conversion pursuant to Section 5(a), the Company shall deliver as promptly as practicable written notice to each Holder specifying: (A) the Stockholder Approval Date; (B) the number of shares of Common Stock to be issued in respect of each share of Series B Preferred Stock that is converted; (C) the place or places where certificates or evidence of book-entry notation for such shares of Series B Preferred Stock are to be surrendered for issuance of certificates or evidence of book-entry notation representing shares of Common Stock; and (D) that dividends on the shares of Series B Preferred Stock to be converted will cease to accrue on such Stockholder Approval Date. Unless the shares of Common Stock issuable upon such conversion are to be issued in the same name as the name in which such shares of Series B Preferred Stock are registered, each share surrendered for mandatory conversion shall be accompanied by instruments of transfer, in form satisfactory to the Company, duly executed by the holder thereof or such holder’s duly authorized attorney and an amount sufficient to pay any transfer or similar tax in accordance with Section 15(f).

(ii)    The conversion shall be deemed to have been effected at the close of business on the Stockholder Approval Date. At such time: (A) the person in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such mandatory conversion shall be deemed to have become the holder of record of the shares of Common Stock represented thereby at such time; and (B) such shares of Series B Preferred Stock so converted shall no longer be deemed to be outstanding, and all rights of a holder with respect to such shares shall immediately terminate except the right to receive the Common Stock and other amounts payable pursuant to this Section 5.

(iii)    [reserved]

(iv)    In connection with the mandatory conversion of shares of Series B Preferred Stock, no fractions of shares of Common Stock shall be issued, but in lieu thereof the Company shall pay an amount of cash in respect of such fractional interest equal to such fractional interest multiplied by the Market Value per share of Common Stock on the Stockholder Approval Date.

Section 6.    Settlement upon Conversion. The Company shall satisfy its obligation to deliver Conversion Shares (or such other class or series of securities into which the Series B Preferred Stock is then convertible) upon conversion of Series B Preferred Stock by delivering to each Holder surrendering shares of Series B Preferred Stock for conversion a number of shares of Common Stock (or such other class or series of securities into which the Series B Preferred

5

Stock is then convertible) equal to the Conversion Shares to which such Holder is entitled pursuant to Section 5 (provided that the Company will deliver cash in lieu of fractional shares), as soon as practicable but in no event later than the fifth Business Day following the Stockholder Approval Date.

Section 7.    Anti-dilution Adjustments. (a) The Conversion Price shall be subject to the following adjustments from time to time:

(i)    Stock Dividends. In case the Company shall pay or make a dividend or other distribution on the Common Stock in Common Stock, the Conversion Price, as in effect at the opening of business on the day following the date fixed for the determination of stockholders of the Company entitled to receive such dividend or other distribution, shall be adjusted by multiplying such Conversion Price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such adjustment to become effective immediately after the opening of business on the day following the date fixed for such determination; provided, however, that no such adjustment to the Conversion Price shall be made if the Holders would be entitled to receive such dividend or other distribution pursuant to Section 2.

(ii)    Stock Purchase Rights. In case the Company shall issue to all holders of its Common Stock options, warrants or other rights entitling them to subscribe for or purchase shares of Common Stock for a period expiring within 60 days from the date of issuance of such options, warrants or other rights at a price per share of Common Stock less than 100% of the Market Value on the date fixed for the determination of stockholders of the Company entitled to receive such options, warrants or other rights (other than pursuant to a dividend reinvestment, share purchase or similar plan), the Conversion Price in effect at the opening of business on the day following the date fixed for such determination shall be adjusted by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock which the aggregate consideration expected to be received by the Company upon the exercise, conversion or exchange of such options, warrants or other rights (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) would purchase at such Market Value and the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock so offered for subscription or purchase, either directly or indirectly, such adjustment to become effective immediately after the opening of business on the day following the date fixed for such determination; provided, however, that no such adjustment to the Conversion Price shall be made if the Holders would be entitled to receive such options, warrants or other rights pursuant to Section 2; provided, further, however, that if any of the foregoing options, warrants or other rights are only exercisable upon the occurrence of a Triggering Event, then the Conversion Price will not be adjusted until the earlier of (1) such Triggering Event occurs or (2) the date when the conversion of Series B Preferred Stock into Common Stock occurs.

6

(iii)    Stock Splits, Reverse Splits and Combinations. In case outstanding shares of Common Stock shall be subdivided, split or reclassified into a greater number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision, split or reclassification becomes effective shall be proportionately reduced, and, conversely, in case outstanding shares of Common Stock shall be combined or reclassified into a smaller number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such combination or reclassification becomes effective shall be proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision, split, reclassification or combination becomes effective.

(iv)    Debt, Asset or Security Distributions. (A) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness, assets or securities (but excluding any dividend or distribution of options, warrants or other rights referred to in paragraph (ii) of this Section 7(a), any dividend or distribution paid exclusively in cash, any dividend or distribution of shares of Capital Stock of any class or series, or similar equity interests, of or relating to a Subsidiary or other business unit in the case of a Spin-off referred to in the next subparagraph, or any dividend or distribution referred to in paragraph (i) of this Section 7(a)), the Conversion Price shall be reduced by multiplying the Conversion Price in effect immediately prior to the close of business on the date fixed for the determination of stockholders of the Company entitled to receive such distribution by a fraction, the numerator of which shall be such Market Value minus the fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) of the portion of the assets or evidences of indebtedness so distributed applicable to one share of Common Stock and the denominator of which shall be the Market Value on the date fixed for such determination, such adjustment to become effective immediately prior to the opening of business on the day following the date fixed for the determination of stockholders of the Company entitled to receive such distribution. In any case in which this subparagraph (iv)(A) is applicable, subparagraph (iv)(B) of this Section 7(a) shall not be applicable. No adjustment to the Conversion Price shall be made if the Holders would be entitled to receive such dividend or distribution pursuant to Section 2.

(A)    In the case of a Spin-off, the Conversion Price in effect immediately prior to the close of business on the date fixed for determination of stockholders of the Company entitled to receive such distribution shall be reduced by multiplying the Conversion Price by a fraction, the numerator of which shall be the Market Value minus the fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) of the shares (or fractions thereof) of Capital Stock or similar equity interests so distributed applicable to one share of Common Stock and the denominator of which shall be the Market Value. Any adjustment to the Conversion Price under this subparagraph (iv)(B) will occur on the date that is the earlier of (1) the tenth Trading Day from, and including, the effective date of the Spin-off and (2) the date of the Initial Public Offering of the securities being distributed in the Spin-off, if that Initial Public Offering is effected simultaneously with the Spin-off. No adjustment to the Conversion Price shall be made if the Holders would be entitled to receive such dividend or distribution pursuant to Section 2.

7

(v)    Tender Offers. In the case that a tender or exchange offer made by the Company or any Subsidiary of the Company for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended through the expiration thereof) shall require the payment to stockholders of the Company (based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of Purchased Shares) of aggregate consideration having a fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) per share of Common Stock that exceeds the Closing Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, then, immediately prior to the opening of business on the day after the date of the last time (the “Expiration Time”) tenders or exchanges could have been made pursuant to such tender or exchange offer (as amended through the expiration thereof), the Conversion Price shall be reduced by multiplying the Conversion Price immediately prior to the close of business on the date of the Expiration Time by a fraction (A) the numerator of which shall be equal to the product of (x) the Market Value on the date of the Expiration Time and (y) the number of shares of Common Stock outstanding (including any tendered or exchanged shares) on the date of the Expiration Time, and (B) the denominator of which shall be equal to (x) the product of (I) the Market Value on the date of the Expiration Time and (II) the number of shares of Common Stock outstanding (including any tendered or exchanged shares) on the date of the Expiration Time less the number of all shares validly tendered or exchanged, not withdrawn and accepted for payment on the date of the Expiration Time (such validly tendered or exchanged shares, up to any such maximum, being referred to as the “Purchased Shares”) plus (y) the amount of cash plus the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders of the Company pursuant to the tender or exchange offer (assuming the acceptance, up to any maximum specified in the terms of the tender or exchange offer, of Purchased Shares).

(b)    De Minimis Adjustments. Notwithstanding anything herein to the contrary, no adjustment under this Section 7 need be made to the Conversion Price unless such adjustment would require an increase or decrease of at least 1.0% of the Conversion Price then in effect. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent adjustment, if any, which, together with any adjustment or adjustments so carried forward, shall result in an increase or decrease of at least 1.0% of such Conversion Price. No adjustment under this Section 7 shall be made if such adjustment will result in a Conversion Price that is less than the par value of the Common Stock.

(c)    Tax-Related Adjustments. The Company may make such reductions in the Conversion Price, in addition to those required by this Section 7, as the Board of Directors considers advisable in order to avoid or diminish any income tax to any holders of shares of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes. In the event the Company elects to make such a reduction in the Conversion Price, the Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder if and to the extent that such laws and regulations are applicable in connection with the reduction in the Conversion Price.

8

(d)    Stockholder Rights Plans. Upon conversion of the Series B Preferred Stock, to the extent that the Holders receive Common Stock, such Holders shall receive, in addition to the shares of Common Stock, the rights issued under any future stockholder rights plan the Company may establish whether or not such rights are separated from the Common Stock prior to conversion. A distribution of rights pursuant to any stockholder rights plan will not result in an adjustment to the Conversion Price pursuant to Section 7(a)(ii) or 7(a)(iv), provided that the Company has provided for the Holders to receive such rights upon conversion, and provided, further, that the Holders shall not be permitted to receive such rights to the extent that any of the Holders or their respective Affiliates is the “Acquiring Person” under such stockholder rights plan or otherwise participates in any manner in the event that triggers the distribution of rights thereunder.

(e)    Notice of Adjustment. Whenever the Conversion Price is adjusted in accordance with this Section 7, the Company shall (i) compute the Conversion Price in accordance with this Section 7 and prepare and transmit to the Transfer Agent an Officer’s Certificate setting forth the Conversion Price, the method of calculation thereof in reasonable detail, and the facts requiring such adjustment and upon which such adjustment is based and (ii) as soon as practicable following the occurrence of an event that requires an adjustment to the Conversion Price pursuant to this Section 7 (or if the Company is not aware of such occurrence, as soon as practicable after becoming so aware), the Company or, at the request and expense of the Company, the Transfer Agent shall provide a written notice to the Holders of the occurrence of such event and a statement setting forth in reasonable detail the method by which the adjustment to the Conversion Price was determined and setting forth the adjusted Conversion Price.

(f)    Reversal of Adjustment. If the Company shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution, and shall thereafter (and before the dividend or distribution has been paid or delivered to stockholders) legally abandon its plan to pay or deliver such dividend or distribution, then thereafter no adjustment in the Conversion Price then in effect shall be required by reason of the taking of such record.

(g)    Exceptions to Adjustment. The applicable Conversion Price shall not be adjusted:

(i)    upon the issuance of any shares of Common Stock or options or rights to purchase shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any such plan;

(ii)    upon the issuance of any shares of Common Stock or options or rights to purchase shares of Common Stock pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries;

(iii)    upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the Issue Date;

9

(iv)    upon the issuance of any shares of Common Stock or any other security of the Company in connection with acquisitions of assets or securities of another Person, including with respect to any merger or consolidation or similar transaction, including any such obligations in effect as of the Issue Date and any such obligations entered into after the Issue Date;

(v)    for a change in the par value of the Common Stock;

(vi)    upon the issuance of any shares of Common Stock or any other security of the Company in connection with the exercise of the Warrants;

(vii)    upon the issuance of any shares of Common Stock or any other security of the Company to the Holders or their Affiliates pursuant to the terms of the Stock Purchase Agreement;

(viii)    for accrued and unpaid dividends on the Series B Preferred Stock; or

(ix)    for any other issuance of securities of the Company for which the Holders then holding a majority of the outstanding shares of Series B Preferred Stock provide a waiver of such adjustment in such Holders’ sole discretion.

Section 8.    Redemption

(a)    Redemption at the Holder’s Option. Subject to the terms of this Section 8, at any time after the first anniversary of the Issue Date, any Holder may require the Company to redeem up to one hundred percent (100%) of the outstanding shares of Series B Preferred Stock held by such Holder at such time. Any election by the Holders of Series B Preferred Stock to exercise such Holders’ right of redemption as provided below shall be effected by providing written notice to the Company, which shall set forth the date for such redemption that shall be at least ten (10) business days following the date of such notice.

(b)    Redemption Date; Redemption Price. Any date upon which a redemption is to occur in accordance with this Section 8 shall be referred to as a “Redemption Date.” The redemption price for each share of Series B Preferred Stock redeemed pursuant to this Section 8 shall be the Liquidation Preference plus an amount equal to all accrued and unpaid dividends (the “Redemption Price”). The aggregate Redemption Price in respect of shares of Series B Preferred Stock to be redeemed shall be payable in cash in immediately available funds on the Redemption Date. Following the Company’s receipt of the redemption notice specified in Section 8(a) and until the aggregate Redemption Price has been paid in cash for all shares of Series B Preferred Stock to be redeemed as of the applicable Redemption Date: (A) no cash dividend whatsoever shall be paid or declared, and no distribution shall be made on any capital stock of the Company (other than the Series B Preferred Stock); and (B) no shares of capital stock of the Company (other than the Series B Preferred Stock) or any direct or indirect subsidiary shall be purchased, redeemed, or acquired (and no monies shall be paid into or set aside or made available for a sinking fund or otherwise for the purchase, redemption, or acquisition thereof).

10

(c)    Redemption Prohibited. If, at a Redemption Date, the Company is prohibited under DGCL from redeeming all shares of Series B Preferred Stock for which redemption is required hereunder, then it shall redeem such shares on a pro-rata basis among the holders of Series B Preferred Stock in proportion to the full respective redemption amounts to which they are entitled hereunder to the fullest extent possible under DGCL and shall redeem the remaining shares to be redeemed as soon as the Company is not prohibited from redeeming some or all of such shares under DGCL. The shares of Series B Preferred Stock not redeemed shall remain outstanding and entitled to all of the rights, dividends and preferences provided in this Certificate and this Section 8(c) shall continue to apply until all shares of Series B Preferred Stock are redeemed.

(d)    Dividend After Redemption Date. From and after the date specified for redemption in the election notice as set forth in Section 8(a), no shares of Series B Preferred Stock subject to redemption shall be entitled to any further dividends; provided, however, that in the event that shares of Series B Preferred Stock are unable to be redeemed and continue to be outstanding in accordance with Section 8(c), such shares shall continue to be entitled to dividends and interest thereon until the date on which such shares are actually redeemed by the Company.

(e)     Surrender of Certificates. Upon receipt of the applicable Redemption Price by certified check or wire transfer, Holders of shares of Series B Preferred Stock to be redeemed shall surrender the certificate or evidence of book-entry notation for such shares of Series B Preferred Stock to the Company, duly assigned or endorsed for transfer (or accompanied by duly executed stock powers relating thereto).

Section 9.    Recapitalizations, Reclassifications and Changes in the Company’s Stock. In the event of any reclassification of outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value), or any consolidation or merger of the Company with or into another Person (other than with a Subsidiary of the Company) or any merger of another Person with or into the Company (other than a consolidation or merger in which the Company is the resulting or surviving Person and that does not result in any reclassification or change of outstanding Common Stock), or any sale or other disposition to another Person of all or substantially all of the assets of the Company (computed on a consolidated basis) (any of the foregoing, a “Transaction”), upon conversion of its shares of Series B Preferred Stock, a Holder will be entitled to receive the kind and amount of securities (of the Company or another issuer), cash and other property receivable upon such Transaction by a holder of the number of shares of Common Stock into which such shares of Series B Preferred Stock were convertible immediately prior to such Transaction, after giving effect to any adjustment event or, in the event holders of Common Stock have the opportunity to elect the form of consideration to be received in any Transaction, the weighted average of the forms and amounts of consideration received by the holders of the Common Stock. In the event that at any time, as a result of an adjustment made pursuant to this Certificate of Designation, the Holders shall become entitled upon conversion to any securities other than, or in addition to, shares of Common Stock, thereafter the number or amount of such other securities so receivable upon conversion shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Common Stock set forth in this Certificate of Designation.

11

Section 10.    Consolidation, Merger and Sale of Assets. (a) The Company, without the consent of the Holders, may consolidate with or merge into any other Person or convey, transfer or lease all or substantially all its assets to any Person or may permit any Person to consolidate with or merge into, or transfer or lease all or substantially all its properties to, the Company (any of the foregoing, “Reorganization”); provided, however, that (i) the shares of Series B Preferred Stock will become the kind and amount of securities of such successor, transferee or lessee, cash and other property receivable by a holder of the number of shares of Common Stock into which such shares of Series B Preferred Stock were convertible immediately prior to such Reorganization; and (ii) the Company delivers to the Transfer Agent an Officer’s Certificate and an Opinion of Counsel, acceptable to the Transfer Agent, stating that such Reorganization complies with this Certificate of Designation.

(a)    Upon any consolidation by the Company with, or merger by the Company into, any other Person or any conveyance, transfer or lease of all or substantially all the assets of the Company as described in Section 10(a), the successor resulting from such consolidation or into which the Company is merged or the transferee or lessee to which such conveyance, transfer or lease is made, will succeed to, and be substituted for, and may exercise every right and power of, the Company under the shares of Series B Preferred Stock, and thereafter, except in the case of a lease, the predecessor (if still in existence) will be released from its obligations and covenants with respect to the Series B Preferred Stock.

Section 11.    Notices. (a) When the Company is required, pursuant to this Certificate of Designation, to give notice to Holders by issuing a press release, rather than directly to Holders, the Company shall do so in a public medium that is customary for such press release; provided, however, that in such cases, publication of a press release through the Dow Jones News Service shall be considered sufficient to comply with such notice obligation.

(a)    When the Company is required, pursuant to this Certificate of Designation, to give notice to Holders without specifying the method of giving such notice, the Company shall do so by sending notice via first class mail or by overnight courier to the Holders of record as of a reasonably current date.

Section 12.    Transfer of Securities. (a) The shares of Series B Preferred Stock and the shares of Common Stock issuable upon conversion of the Series B Preferred Stock (collectively, the “Securities”) have not been registered under the Securities Act or any other applicable securities laws and may not be offered or sold except in compliance with the registration requirements of the Securities Act and any other applicable securities laws, or pursuant to an exemption from registration under the Securities Act and any other applicable securities laws, or in a transaction not subject to such laws.

(a)    Except in connection with a registration statement relating to the Securities, if shares of Series B Preferred Stock in certificated form are delivered upon the transfer, exchange or replacement of shares of Series B Preferred Stock bearing the Restricted Stock Legend, or if a request is made to remove such Restricted Stock Legend on shares of

12

Series B Preferred Stock, the shares of Series B Preferred Stock so issued shall bear the Restricted Stock Legend and the Restricted Stock Legend shall not be removed unless there is delivered to the Company and the Transfer Agent such satisfactory evidence, which may include an Opinion of Counsel licensed to practice law in the State of New York, as may be reasonably required by the Company, that such shares of Series B Preferred Stock are not “restricted securities” within the meaning of Rule 144 under the Securities Act. Upon provision of such satisfactory evidence, the Transfer Agent, at the direction of the Company, shall countersign and deliver shares of Series B Preferred Stock that do not bear the Restricted Stock Legend.

(b)    Shares of Common Stock issued upon a conversion of the shares of Series B Preferred Stock bearing the Restricted Stock Legend, prior to the first anniversary of the Issue Date, shall be in global form and bear a restricted common stock legend that corresponds to the Restricted Stock Legend (the “Restricted Common Stock Legend”).

(c)    The Company will refuse to register any transfer of Securities that is not made in accordance with the provisions of the Restricted Stock Legend or the Restricted Common Stock Legend, as applicable, provided that the provisions of this Section 12(c) shall not be applicable to any Security that does not bear any Restricted Stock Legend or any Restricted Common Stock Legend.

Section 13.    Certain Tax Matters. The Company and the Holders acknowledge and agree that it is intended that the Series B Preferred Stock not constitute “preferred stock” within the meaning of Section 305 of the Internal Revenue Code of 1986, as amended, and the Treasury Regulations promulgated thereunder, and that neither the Company nor the Holders shall treat the Series B Preferred Stock as such. The Company shall be entitled to deduct and withhold from any payment of cash, shares of Series B Preferred Stock, shares of Common Stock or other consideration deliverable to a Holder of a share of Series B Preferred Stock, any amounts required to be deducted or withheld under applicable U.S. federal, state, local or foreign tax laws with respect to such payment or issuance. In the event the Company paid withholding taxes to a governmental authority in respect of any amount treated as a distribution on a share of Series B Preferred Stock, the Company shall be entitled to deduct any such taxes from any subsequent payment of cash, shares of Series B Preferred Stock, shares of Common Stock or other consideration otherwise deliverable to a Holder of a share of Series B Preferred Stock.

Holder agrees with the Company that this Warrant to Purchase Shares of the Company (this “Warrant” or this “Agreement”) is issued, and all rights hereunder shall be held, subject to all of the conditions, limitations and provisions set forth herein.

This Warrant was issued in conjunction with that certain Share Purchase Agreement by and between the Company and Weichai America Corp.

(c)    Acceleration. Notwithstanding the foregoing, to the extent that, prior to the beginning of the Term set forth in Section 1(b) herein, (i) the Company is in default under the TPG Credit Agreement (as defined under Share Purchase Agreement) or any refinancings or replacements thereof, or (ii) any other credit agreement, bond, note, mortgage, indenture or other debt financing or refinancing arrangement with an outstanding obligation of $5,000,000 or more, (ii) as a result of such default, the lender under such debt financing arrangement has accelerated all outstanding obligations of the Company under such debt financing arrangement by written notice to the Company thereof (the amount of such accelerated obligation, the “Accelerated Obligation”), and (iii) the Company does not cure such default within any cure period set out in such notice of default or within 10 days in case there is no cure period set out in such notice of default, if any (the “Cure Period”), the Warrant shall become exercisable for a number of shares of Common Stock equal to the ratio of (x) the amount of the Accelerated Obligation, divided by (y) the Exercise Price for the Warrant, and the portion of the Warrant that is so exercisable shall continue to be exercisable for a period of ten (10) days following the expiration of the Cure Period (each such period, an “Accelerated Term”). To the extent such exercisable portion of the Warrant is not fully exercised during such Accelerated Term, the Warrant (including such portion) shall continue to be exercisable pursuant to the terms hereof. Notwithstanding the foregoing, if the Company has cured such default on or prior to the date of Exercise of the Warrant pursuant to this Section 1(c) or the Holder fails to exercise the Warrant within the Accelerated Term, the Warrant shall no longer be accelerated pursuant to this Section 1(c) but still be exercisable pursuant to Section 1(b).

If Holder intends to Exercise the Warrant and provides a written notice indicating the number of Warrant Shares to be Exercised and the approximate Date of Exercise at any time at least one (1) month prior to the start of the Term, the Company shall take all necessary actions in a timely manner to obtain consents or approvals from any and all third parties and government authorities that failure of which would constitute a Material Adverse Effect (as defined in the Share Purchase Agreement) (“Material Third Party Consents”) prior to the Date of Exercise.

Notwithstanding the foregoing, the Company shall not be required to pay any tax or other charge imposed in connection with any transfer involved in the issuance of any certificate for Exercise Shares in any name other than that of the original registered holder of this Warrant.

(d)    Delivery Failure. In addition to any other remedies which may be available to the Holder, in the event that the Company fails for any reason to effect delivery of the Exercise Shares by the end of the Delivery Period (a “Delivery Failure”), the Holder will be entitled to revoke all or part of the relevant Exercise Form by delivery of a notice to such effect to the Company not later than three (3) Trading Days after the end of the Delivery Period, whereupon the Company and the Holder shall each be restored to their respective positions immediately prior to the delivery of such notice, including without limitation the return of the Warrant to the Holder and the return of certificates representing Exercise Shares to the Company.

(e)    Legends.

(i)    Restrictive Legend. The Holder understands that this Warrant shall bear a restrictive legend in substantially the form set forth on the first page of this Warrant (and a stop-transfer order may be placed against transfer of such securities). The Holder further understands that until such time as the Exercise Shares have been registered under the Securities Act as contemplated by the Investor Rights Agreement, or otherwise may be sold pursuant to Rule 144 under the Securities Act or an exemption from registration under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold, the Exercise Shares shall bear a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of the certificates for such securities):

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER SAID ACT, OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SAID ACT INCLUDING, WITHOUT LIMITATION, PURSUANT TO RULES 144 OR 144A UNDER SAID ACT OR PURSUANT TO A PRIVATE SALE EFFECTED UNDER

APPLICABLE FORMAL OR INFORMAL SEC INTERPRETATION OR GUIDANCE, SUCH AS A SO-CALLED “4(1) AND A HALF” SALE”, SUBJECT TO DELIVERY OF AN OPINION, AS PROVIDED IN THE WARRANT, DATED AS OF                 , 20    , ISSUED BY THE COMPANY.”

“THE SALE, TRANSFER OR ASSIGNMENT OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN INVESTOR RIGHTS AGREEMENT DATED AS OF             , 2017, AS AMENDED FROM TIME TO TIME, AMONG THE COMPANY AND CERTAIN HOLDERS OF ITS OUTSTANDING SECURITIES. COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY.”

(ii)    Removal of Restrictive Legends. The certificates evidencing the Exercise Shares shall not contain any legend restricting the transfer thereof (including the legend set forth above in subsection 2(e)(i)): (A) while a registration statement (including a Registration Statement, as defined in the Investor Rights Agreement) covering the resale of such security is effective under the Securities Act, or (B) following any sale of such Exercise Shares pursuant to Rule 144, or (C) if such Exercise Shares are eligible for sale under Rule 144(b)(1), or (D) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC) (collectively, the “Unrestricted Conditions”). If the Unrestricted Conditions are satisfied, the Company shall cause its counsel to issue a legal opinion to the Transfer Agent promptly after the Unrestricted Conditions are satisfied, if required and to the extent permitted by the Transfer Agent, to effect the issuance of the Exercise Shares without a restrictive legend or removal of the legend hereunder. The Company agrees that, following the Effective Date, at such time as the Unrestricted Conditions are met or such legend is otherwise no longer required under this Section 2(e), it will, no later than five (5) Trading Days following the delivery (the “Unlegended Shares Delivery Deadline”) by the Holder to the Company of a certificate representing Exercise Shares containing a restrictive legend (such fifth Trading Day, the “Legend Removal Date”), deliver or cause to be delivered to such Holder a certificate (or electronic transfer) representing such shares that is free from all restrictive and other legends. For purposes hereof, “Effective Date” shall mean the date that the Registration Statement that the Company is required to file pursuant to the Investor Rights Agreement has been declared effective by the SEC.

(iii)    Sale of Unlegended Shares. Holder agrees that the removal of the restrictive legend from any certificates representing securities as set forth in Section 2(e) above is predicated upon the Company’s reliance that the Holder will sell, transfer, assign, pledge, hypothecate or otherwise dispose of this Warrant or any Exercise Shares pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if such securities are sold pursuant to a Registration Statement, they will be sold in compliance with the plan of distribution set forth therein.

(f)    Cancellation of Warrant. This Warrant shall be canceled upon the earliest to occur of the following: (i) expiration at the end of the Term; (ii) the full Exercise of this Warrant; or (iii) the consummation of a Major Transaction. If this Warrant is partially (and not fully) Exercised, Holder shall be entitled to receive a new Warrant (containing terms identical to this Warrant) representing any unexercised and unexpired portion of this Warrant. In the event of a Major Transaction (as defined below), any portion of this Warrant that is not Exercised pursuant to the terms of this Warrant prior to the closing of such Major Transaction shall be cancelled and terminated without further action by the Holder or the Company upon consummation of such Major Transaction.

(g)     Delivery of Electronic Shares. In lieu of delivering physical certificates representing the Exercise Shares or shares of Common Stock submitted for legend removal, provided the Transfer Agent is participating in the DTC Fast Automated Securities Transfer (“FAST”) program, upon written request of the Holder, the Company shall use commercially reasonable efforts to cause its Transfer Agent to electronically transmit such securities by crediting the account of the Holder’s prime broker with DTC through its Deposit Withdrawal Agent Commission (DWAC) system. The time periods for delivery and penalties described herein shall apply to the electronic transmittals described herein. Any delivery not effected by electronic transmission shall be effected by delivery of physical certificates.

(h)    Buy-In. In addition to any other rights available to the Holder, if the Company fails to cause its Transfer Agent to transmit to the Holder a certificate or certificates, or electronic shares through DWAC, representing Exercise Shares on or before the end of the applicable Delivery Period (other than a failure caused by incorrect or incomplete information provided by Holder to the Company hereunder), and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise), or the Holder’s brokerage firm otherwise purchases shares of Warrant Shares to deliver in satisfaction of a sale by the Holder of the Exercise Shares that the Company was required to deliver to the Holder in connection with such Exercise (a “Buy-In”), then the Company shall (1) pay in cash to the Holder the amount by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Warrant Shares so purchased exceeds (y) the amount (the “Sales Price”) obtained by multiplying (A) the number of Exercise Shares that the Company was required to deliver to the Holder in connection with the Exercise at issue times (B) the price at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Exercise Shares for which such Exercise was not timely honored or deliver to the Holder the Exercise Shares that would have been issued had the Company timely complied with its Exercise and delivery obligations hereunder. For example, if the Holder purchases Warrant Shares having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted Exercise to cover the sale of Warrant Shares with an aggregate Sales Price of $10,000, under clause (1) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice, within three (3) Trading Days after the occurrence of a Buy-In, indicating the amounts payable to the Holder in respect of such Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing Exercise Shares upon Exercise of the Warrant as required pursuant to the terms hereof; provided, however, that the Holder shall not be entitled to both (i) reinstate the portion of the Warrant and equivalent number of Exercise Shares for which such Exercise was not timely honored and (ii) receive such Exercise Shares.

(a)    Exercise Price. Subject to adjustment pursuant to terms of Section 3(b) and 5(f) herein, the exercise price per exercised Warrant Share (“Exercise Price”) shall be equal to the average Volume Weighted Average Price of one (1) share of the Company’s Common Stock during the twenty (20)

consecutive Trading Day period immediately preceding the Date of Exercise multiplied by 85%; provided that in the case that Delisting Condition exists, the Exercise Price shall be equal to the following: (x) the average Volume Weighted Average Price of one (1) share of the Company’s Common Stock during the twenty (20) consecutive Trading Day (or if the Common Stock is not then listed or quoted on NASDAQ) Business Day (as applicable) period immediately preceding the Date of Exercise multiplied by 50%; or (y) if no Volume Weighted Average Price is available for the twenty (20) consecutive Trading Day period immediately preceding the Date of Exercise, the Volume Weighted Average Price for twenty (20) Trading Days which are most recently available preceding the Date of Exercise multiplied by 50%.

Payment of the Exercise Price shall be made in cash, cashier’s check or wire transfer.

(b)    Adjustment to the Exercise Price.

(A) Subject to the limitation set forth in Section 3(b)(C) below, in the event that the Company’s 2017 EBITDA is less than $22 million, the aggregate Exercise Price for the Warrant Shares shall be adjusted by deducting an amount derived from the following formula (“EBITDA Adjustment Amount”):

EBITDA Adjustment Amount = $27.5 million – (2017 EBITDA × 1.25)

(B)    Subject to the limitation set forth in Section 3(b)(C) below, to the extent that the net book value per share of Common Stock as of December 31, 2016 (based on the audited consolidated balance sheet of the Company and its subsidiaries as of December 31, 2016) (“Actual 2016 Net Book Value Per Share“) is less than $8.00, then the aggregate Exercise Price for the Warrant Shares shall be further adjusted by deducting an amount derived from the following formula (“Net Book Value Adjustment Amount”):

Net Book Value Adjustment Amount = ($8.00 - Actual 2016 Net Book Value Per Share) × 7,500,000

provided that, if the Actual 2016 Net Book Value Per Share is equal to or greater than $8.00, there will be no adjustment.

(C)    Notwithstanding the foregoing, the aggregate amount of the EBITDA Adjustment Amount and the Net Book Value Adjustment Amount (collectively, “Aggregate Adjustment Amount”) shall not exceed $15 million. If the aggregate Exercise Price for the Warrant Shares is less than the Aggregate Adjustment Amount, then following the full Exercise of the Warrant the Company shall be liable to pay the shortfall between the aggregate Exercise Price for the Warrant Shares and the Aggregate Adjustment Amount to the Holder. In the event that either the 2017 EBITDA or Actual 2016 Net Book Value Per Share is zero or a negative number, then 2017 EBITDA or Actual 2016 Net Book Value Per Share, as the case may be, shall be deemed to be 0.01 for the purposes of calculation of the adjustments.

(c)    Payment of Additional Amounts for Warrant Shares. In the event that the Holder exercises all or any part of the Warrant during the Accelerated Term for the Exercise Price pursuant to Section 3(a)(x) or (y) and (i) there exists a Delisting Condition at the time of exercise of the Warrant; but (ii) the Company Common Stock is listed on Nasdaq as of the date that is the eighteen (18) month anniversary of the Closing, the Holder shall pay to the Company by wire transfer of immediately available funds to an account designated in writing by the Company, promptly following the date that is the eighteen (18) month anniversary of the Closing, an additional amount equal to the quotient of (a) the aggregate Exercise Price paid in respect of all of the Warrant Shares exercised by the Holder during the Accelerated Term, multiplied by (b) 0.7. In the event that (i) there is no Delisting Condition when the Holder exercises the Warrant during the Accelerated Term; and (ii) the Company Common Stock is not listed on Nasdaq as of the date that is the eighteen (18) month anniversary of the Closing, the Company shall pay to the Holder by wire transfer of immediately available funds to an account designated in writing by the Holder, promptly following the date that is the eighteen (18) month anniversary of the Closing, an additional amount equal to the quotient of (a) the aggregate Exercise Price paid in respect of all of the Warrant Shares exercised by the Holder during the Accelerated Term, multiplied by (b) 35/85.

(d)    Dispute Resolution. In the case of a dispute as to the determination of the closing price or the Volume Weighted Average Price of the Company’s Common Stock or the arithmetic calculation of the Exercise Price or Market Price, the Company shall submit the disputed determinations or arithmetic calculations via facsimile within four (4) Business Days of receipt, or deemed receipt, of the Exercise Notice, or other event giving rise to such dispute, as the case may be, to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation within two (2) Business Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two (2) Business Days submit via facsimile (i) the disputed determination of the closing price or the Volume Weighted Average Price of the Company’s Common Stock to an independent, reputable investment bank selected by the Company and approved by the Holder, which approval shall not be unreasonably withheld or delayed or (ii) the disputed arithmetic calculation of the Exercise Price or Market Price to the Company’s independent, outside accountant, or another accounting firm of national standing selected by the Company. The Company shall cause the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than the later of (i) five (5) Business Days from the time it receives the disputed determinations or calculations or (ii) five (5) Business Days from the selection of the investment bank and accounting firm, as applicable. Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error.

(a)    Transfer Rights. Subject to the provisions of Section 8 of this Warrant, this Warrant may be transferred on the books of the Company, in whole or in part, in person or by attorney, upon surrender of this Warrant properly completed and endorsed. This Warrant shall be canceled upon such surrender and, as soon as practicable thereafter, the person to whom such transfer is made shall be entitled to receive a new Warrant or Warrants as to the portion of this Warrant transferred, and Holder shall be entitled to receive a new Warrant as to any portion hereof retained.

(b)    Registrable Securities. Subject to the terms of the Investor Rights Agreement, the Warrant Shares issuable upon the Exercise of this Warrant may be registered under the Securities Act as contemplated by the Investor Rights Agreement.

(a)    Participation. The Holder, as the holder of this Warrant, shall be entitled to receive such dividends paid and distributions of any kind made to the holders of equity securities of the Company to the same extent as if the Holder had Exercised this Warrant (without regard to any limitations on exercise herein or elsewhere and without regard to whether or not a sufficient number of shares are authorized and reserved to effect any such exercise and issuance) and had held such shares of equity securities on the record date for such dividends and distributions. Payments under the preceding sentence shall be made concurrently with the dividend or distribution to the holders of equity securities.

(b)    Recapitalization or Reclassification; Consolidation, Merger or Sale. If the Company shall at any time effect a stock split, payment of stock dividend, recapitalization, reclassification or other similar transaction of such character that the shares of equity securities shall be changed into or become

exchangeable for a larger or smaller number of shares, then upon the effective date thereof, the number of shares of Warrant Shares which Holder shall be entitled to purchase upon Exercise of this Warrant shall be increased or decreased, as the case may be, in direct proportion to the increase or decrease in the number of shares of equity securities by reason of such stock split, payment of stock dividend, recapitalization, reclassification or similar transaction, and the Exercise Price shall be, in the case of an increase in the number of shares, proportionally decreased and, in the case of decrease in the number of shares, proportionally increased. In addition, if any recapitalization, reclassification or reorganization of the share capital of the Company, or any consolidation or merger of the Company with another corporation, or the sale of all or substantially all of its shares and/or assets or other transaction (including, without limitation, a sale of substantially all of its assets followed by a liquidation) shall be effected in such a way that holders of shares of equity securities shall be entitled to receive shares, securities or other assets or property (a “Change”), then, lawful and adequate provisions shall be made by the Company whereby the Holder shall thereafter have the right to purchase and receive (in lieu of the shares of Warrant Shares immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby) such shares, securities or other assets or property as may be issued or payable with respect to or in exchange for the number of outstanding shares of equity securities which such Holder would have been entitled to receive had such Holder exercised this Warrant immediately prior to the consummation of such Change. The provisions of this Section 5(b) shall similarly apply to successive Changes. The Company shall give Holder the same notice it provides to holders of equity securities of any transaction or Change described in this Section 5(b).

(c)    Rights Upon Major Transaction.

(i)    Major Transaction. In the event that a Major Transaction (as defined below) is consummated prior to the beginning of the Term, the Warrant shall expire and shall not be exercisable. In the event that a Major Transaction is consummated during the Term, then the Holder shall have the right to exercise this Warrant and to make such exercise effective immediately prior to the consummation of such Major Transaction.

Consummation of each of the following events shall constitute a “Major Transaction”:

(A)    a consolidation, merger, exchange of shares, recapitalization, reorganization, business combination or other similar event, following which the holders of Common Stock immediately preceding such consolidation, merger, exchange, recapitalization, reorganization, combination or event either (a) no longer hold a majority of the shares of Common Stock or a majority of the voting power of the Successor Entity on a fully diluted basis or (b) no longer have the ability to elect a majority of the board of directors of the Company or the Successor Entity (collectively, a “Change of Control Transaction”); or

(B)    a purchase, tender or exchange offer (other than any purchase, tender or exchange offer made by the Holder or its Affiliates) made to the holders of outstanding shares of equity securities, such that following the consummation of such purchase, tender or exchange offer a Change of Control Transaction shall have occurred.

(ii)    Notice of Major Transaction. At least fifteen (15) days prior to the consummation of any Major Transaction during the Term, but, in any event, within two (2) Trading Days following the date of the

public announcement of any Major Transaction which is reasonably expected to be consummated during the Term, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a “Major Transaction Notice”).

For purposes hereof:

“Eligible Market” means NASDAQ, the New York Stock Exchange, Inc., the NYSE Arca, the NASDAQ Capital Market, the NASDAQ Global Select Market or the NYSE Alternext U.S. or any successor exchanges or markets thereof.

“Parent Entity” of a Person means an entity that, directly or indirectly, controls the applicable Person and whose common stock or equivalent equity security is quoted or listed on an Eligible Market, or, if there is more than one such Person or Parent Entity, the Person or Parent Entity with the largest public market capitalization as of the date of consummation of a Major Transaction.

“Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization, any other entity and a government or any department or agency thereof.

(d)    Adjustments: Additional Shares, Securities or Assets. In the event that at any time, as a result of an adjustment made pursuant to this Section 5 or otherwise, Holder shall, upon Exercise of this Warrant, become entitled to receive shares and/or other securities or assets (other than Warrant Shares) then, wherever appropriate, all references herein to Warrant Shares shall be deemed to refer to and include such shares and/or other securities or assets; and thereafter the number of such shares and/or other securities or assets shall be subject to adjustment from time to time in a manner and upon terms as nearly equivalent as practicable to the provisions of this Section 5.

(e)    Other Adjustments.

Preferred Shares. In the event that the Stockholder Approval (as defined in the Share Purchase Agreement) is not obtained prior to the Exercise of the Warrant, this Warrant shall be exercisable for a number of shares of the Company’s Preferred Shares (as defined in the Share Purchase Agreement) that are convertible into the number of shares of Common Stock for which this Warrant would otherwise have been exercisable if such Stockholder Approval had been obtained (and the Exercise Price shall be adjusted accordingly), and shall not be exercisable for the purchase of shares of Common Stock.

(f)    Notice of Adjustments. Whenever the Exercise Price is adjusted pursuant to the terms of this Warrant, the Company shall promptly mail to the Holder a notice (an “Exercise Price Adjustment Notice”) setting forth the Exercise Price after such adjustment and setting forth a statement of the facts requiring such adjustment. The Company shall, upon the written request at any time of the Holder, furnish to such Holder a like Warrant setting forth (i) such adjustment or readjustment, (ii) the Exercise Price at the time in effect and (iii) the number of shares of Warrant Shares and the amount, if any, of other securities or property which at the time would be received upon Exercise of the Warrant. For purposes of clarification, whether or not the Company provides an Exercise Price Adjustment Notice pursuant to this Section 5(f), upon the occurrence of any event that leads to an adjustment of the Exercise Price, the Holder would be entitled to receive a number of Exercise Shares based upon the new Exercise Price, as adjusted, for exercises occurring on or after the date of such adjustment, regardless of whether the Holder accurately refers to the adjusted Exercise Price in the Exercise Form.

No fractional shares or scrip representing fractional shares shall be issuable upon the Exercise of this Warrant, but on Exercise of this Warrant, Holder may purchase only a whole number of shares of Warrant

Shares. If, on Exercise of this Warrant, Holder would be entitled to a fractional share of Warrant Shares, such fractional share shall be disregarded and the Company shall calculate and pay to the Holder an amount of cash in lieu of such fractional share, with such cash amount based on the Market Price (as defined in Section 3(a)(ii) above). If more than one Warrant shall be exercised concurrently by Holder, the number of whole shares which shall be issuable upon exercise thereof shall be computed on the basis of the aggregate Warrants so exercised.

From and after the date hereof, the Company shall at all times reserve for issuance such number of authorized and unissued shares of Common Stock (or Series B Preferred Stock or other securities substituted therefor as herein above provided) as shall be sufficient for the Exercise of this Warrant. If at any time the number of shares of equity securities authorized and reserved for issuance is below the number of shares sufficient to permit the Exercise of this Warrant (a “Share Authorization Failure”) (based on the Exercise Price in effect from time to time), the Company will promptly take all corporate action reasonably necessary to authorize and reserve a sufficient number of shares, including, without limitation, calling a special meeting of stockholders to authorize additional shares to meet the Company’s obligations under this Section 7, and using commercially reasonable efforts to obtain stockholder approval of an increase in such authorized number of shares. The Company covenants and agrees that upon the Exercise of this Warrant, other than in the event of a Share Authorization Failure, if any, all Exercise Shares shall be duly and validly issued, fully paid and nonassessable and not subject to preemptive rights, rights of first refusal or similar rights of any Person.

(a)    Registration or Exemption Required. This Warrant has been issued in a transaction exempt from the registration requirements of the Securities Act by virtue of Regulation D and exempt from state registration or qualification under applicable state laws. Neither the Warrant nor the Exercise Shares may be pledged, transferred, sold, assigned, hypothecated or otherwise disposed of except pursuant to an effective registration statement covering the resale of such securities or an exemption to the registration requirements of the Securities Act and applicable state laws including, without limitation, a so-called “4(1) and a half” transaction. This Warrant shall be subject to the restrictions on transfer set forth in the Shareholders Agreement.

(b)    Assignment. Subject to applicable securities laws and Section 8(a) (including the Holder’s compliance with the transfer restrictions set forth in the Shareholders Agreement), the Holder may sell, transfer, assign, pledge, or otherwise dispose of this Warrant, in whole or in part. Holder shall deliver a written notice to Company, substantially in the form of the Assignment attached hereto as Exhibit B, indicating the Person or Persons to whom the Warrant shall be assigned and the respective number of warrants to be assigned to each assignee. The Company shall effect the assignment within five (5) Trading Days (the “Transfer Delivery Period”), and shall deliver to the assignee(s) designated by Holder a Warrant or Warrants of like tenor and terms for the appropriate number of shares. Subject to the foregoing, this Warrant and the rights evidenced hereby shall inure to the benefit of and be binding upon the successors and assigns of the Holder. The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant, and shall be enforceable by any such Holder. For avoidance of doubt, in the event Holder notifies the Company that such sale or transfer is a so called “4(1) and half” transaction, the parties hereto agree that a legal opinion from outside counsel for the Holder delivered to counsel for the Company shall be the only requirement to satisfy an exemption from registration under the Securities Act to effectuate such “4(1) and half” transaction.

The Company hereby covenants and agrees that the Company will not, by amendment of its certificate of incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be reasonably required to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Warrant Shares receivable upon the exercise of this Warrant above the Exercise Price then in effect, and (ii) shall take all such actions as may be reasonably necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Warrant Shares upon the exercise of this Warrant.

The occurrence of each of the following shall be considered to be an “Event of Failure.”

(i) A Delivery Failure Default occurs, where a “Delivery Failure Default” shall be deemed to have occurred if the Company fails to use its reasonable best efforts to deliver Exercise Shares to the Holder within any applicable Delivery Period (other than due to the limitation contained in the provisions contained in the second paragraph of Section 1);

(ii) A Legend Removal Failure occurs, where a “Legend Removal Failure” shall be deemed to have occurred if the Company fails to use its reasonable best efforts to issue Exercise Shares without a restrictive legend, or fails to use it reasonable best efforts to remove a restrictive legend, when and as required under Section 2(e) hereof;

(iii) a Transfer Delivery Failure occurs, where a “Transfer Delivery Failure” shall be deemed to have occurred if the Company fails to use its reasonable best efforts to deliver a Warrant within any applicable Transfer Delivery Period; and

(iv) a Registration Failure (as defined below).

For purposes hereof, “Registration Failure” means that (A) the Company fails to use its best efforts to file with the SEC on or before the filing deadline any Registration Statement required to be filed pursuant to Section 4 of the Investor Rights Agreement, and (B) the Company fails to use commercially reasonable efforts to cause a Registration Statement to be declared effective by the SEC, or fails to use commercially reasonable efforts to keep such Registration Statement current and effective as required in Section 4 of the Investor Rights Agreement, provided that in each case, a Registration Failure shall be deemed to not have occurred if such Registration Failure results from a breach by any holder of a Registrable Security of its obligations pursuant to Section 4 of the Investor Rights Agreement.

(a)    Events Of Default. Each of the following events shall be considered to be an “Event of Default,” unless waived by the Holder:

(i) Failure To Effect Registration. With respect to all Registration Failures, a Registration Failure occurs and remains uncured for a period of more than sixty (60) days after written notice thereof by Holder to the Company; provided that in each case, a Registration Failure shall be deemed to not have occurred if such Registration Failure results from a breach by any holder of a Registrable Security of its obligations pursuant to Section 4 of the Investor Rights Agreement.

(ii) Failure To Deliver Warrant Shares. Other than as provided in Section 13(a) below, a Delivery Failure (as defined above) occurs and the Company fails for any reason to effect delivery of the applicable Exercise Shares for a period of more than twenty (20) days after written notice thereof by Holder to the Company; or at any time, the Company announces or states in writing that it will not honor its obligations to issue shares of Warrant Shares to the Holder upon Exercise by the Holder of the Exercise rights of the Holder in accordance with the terms of this Warrant.

(iii) Legend Removal Failure. A Legend Removal Failure (as defined above) occurs and remains uncured for a period of thirty (30) days after written notice thereof by Holder to the Company; and

(iv) Notice of Major Transaction. The Company has failed to satisfy the requirements of Section 5(c)(iii) above.

(b)    Remedies, Other Obligations, Breaches And Injunctive Relief. The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant, the Share Purchase Agreement and the Investor Rights Agreement, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required.

Nothing in this Warrant shall be construed to confer upon any person other than the Company and Holder any legal or equitable right, remedy or claim under this Warrant and this Warrant shall be for the sole and exclusive benefit of the Company and Holder.

All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that (a) any and all disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision) shall be referred to and finally resolved by arbitration under the Rules of Arbitration of the London Court of International Arbitration (“LCIA Rules”) by one or more arbitrators appointed in accordance with the LCIA Rules (the “Arbitral Tribunal”); (b) the arbitration shall be conducted by a sole arbitrator unless either party objects, in which case the arbitration shall be conducted by a panel of three arbitrators. Where the arbitration is to be conducted by a sole arbitrator, the parties shall attempt to agree upon the selection of the sole arbitrator. If they cannot reach agreement within 30 days from the

commencement of the arbitration, the sole arbitrator shall be appointed by the Court of the LCIA (the “LCIA Court”) in accordance with the LCIA Rules. Where the arbitration is to be conducted by a panel of three arbitrators, each party shall nominate one arbitrator and the two party-nominated arbitrators shall then select the chairman of the Arbitral Tribunal. If the two party-nominated arbitrators are unable to do so within 30 days after the commencement of the arbitration or any mutually agreed extension thereof, the chairman shall be selected by the LCIA Court in accordance with the LCIA Rules; (c) the place of arbitration shall be London; (d) the language of the arbitration shall be English; (e) each arbitrator shall be licensed to practice law in New York; (f) each party shall have the right to apply to any court of competent jurisdiction and/or to the Arbitral Tribunal for an order or award of interim, provisional or conservatory measures in order to maintain the status quo or to protect its rights or property pending arbitration pursuant to this Agreement or for the purpose of compelling a party to arbitrate and seeking temporary or preliminary relief in aid of an arbitration hereunder, and any such application shall not be deemed incompatible with, or a waiver of, the parties’ agreement to arbitrate; (g) the Arbitral Tribunal shall have power to take whatever interim measures it deems necessary, including injunctive relief, specific performance and other equitable relief, including in accordance with the provisions set forth in Section 11(b) of this Agreement. (h) the award rendered by the Arbitral Tribunal shall be final and binding between the parties and not subject to appeal or other recourse; and (i) recognition and enforcement of any award rendered by the Arbitral Tribunal may be sought in any court of competent jurisdiction.

Upon receipt by the Company of evidence of the loss, theft, destruction or mutilation of this Warrant, and (in the case of loss, theft or destruction) of indemnity or security reasonably satisfactory to the Company, and upon surrender and cancellation of this Warrant, if mutilated, the Company shall execute and deliver a new Warrant of like tenor and date.

Notices or demands pursuant to this Warrant to be given or made by Holder to or on the Company shall be sufficiently given or made if sent by certified or registered mail, return receipt requested, postage prepaid or via overnight delivery with a nationally recognized courier service, and addressed, until another address is designated in writing by the Company, to the address set forth in Section 2(a) above. Notices or demands pursuant to this Warrant to be given or made by the Company to or on Holder shall be sufficiently given or made if sent by certified or registered mail, return receipt requested, postage prepaid or via overnight delivery with a nationally recognized courier service, and addressed, to the address of Holder set forth in the Company’s records, until another address is designated in writing by Holder.

of Registrable Securities for which registration is requested and the intended method or methods of distribution thereof. Upon receipt of such a request, the Company shall as soon as practicable cause the Registrable Securities specified in such Demand Notice to be Registered and/or qualified for sale and distribution in such jurisdictions as the Investor may reasonably request, to the extent necessary to permit the disposition (in accordance with the intended methods as aforesaid). The Company shall use its reasonable best efforts to cause such Registration and/or qualification to be complete as soon as practicable, but in no event later than ninety (90) days, after receipt of the Demand Notice. The Company shall be obligated to effect no more than one (1) Registration requested by the Investor during any twelve-month period; provided that a Registration shall not be deemed to have been effected under this Section 4.1 if (i) less than all Registrable Securities set forth in such Demand Notice are Registered in such Registration or (ii) prior to the sale of all of the Registrable Securities included in the applicable registration relating to such request, such Registration is adversely affected by any stop order, injunction or other order or requirement of the Commission (other than any such stop order, injunction, or other requirement of the Commission prompted by act or omission of the Investor). The Investor acknowledges and agrees that the Company is not current in its reporting obligations under the U.S. Securities Laws and that it will not be able to effect a Registration while the Company is not current in its reporting obligations under the U.S. Securities Laws, provided that the Company shall use its reasonable best efforts to become current in its reporting obligations under the U.S. Securities Laws as soon as practicable.

Upon the written request of the Investor, and provided that the Company is eligible to use a Shelf Registration Statement, the Company shall file a Shelf Registration Statement covering all of the Registrable Securities of the Investor as soon as practicable, but in no event later than thirty (30) days, after receipt of such request.

The Company will reimburse any Person intended to be indemnified pursuant to this Section 4.5(a) for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action.

(ii)    The indemnity agreement contained in this Section 4.5(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld or delayed), nor shall the Company be liable for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such Registration by the Investor, underwriter or controlling Person.

(iii)    The foregoing indemnity of the Company is subject to the condition that, insofar as they relate to any defect in a preliminary prospectus but such defect has been eliminated or remedied in the amended prospectus on file with the Commission at the time the applicable Registration becomes effective (the “Final Prospectus”), such indemnity shall not inure to the benefit of any Person if a copy of the Final Prospectus was timely furnished to the Investor or underwriter and was not furnished to the Person asserting the loss, liability, claims or damages at or prior to the time such action is required by the Securities Act.

(b)    Investor Indemnification.

(i)    To the extent permitted by applicable Law, the Investor will indemnify and hold harmless the Company, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) and each of their respective officers, directors, partners, members, managers, shareholders, accountants, attorneys, agents and

20

employees from and against all losses, claims, costs, damages or liabilities (whether joint or several) to which any of the foregoing Persons may become subject, under U.S. Securities Laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based on any untrue statement (or alleged untrue statement) of a material fact contained in any such Registration Statement, including any preliminary prospectus or Final Prospectus contained therein or any amendments or supplements thereto, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse any Person intended to be indemnified pursuant to this Section 4.5(b) for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such Registration Statement, including any preliminary prospectus or Final Prospectus contained therein or any amendments or supplements thereto, in reliance upon and in conformity with written information furnished to the Company and signed by the Investor and intended to be specifically for use therein.

The Investor will not be required to enter into any agreement or undertaking in connection with any Registration providing for any indemnification or contribution on the part of the Investor greater than the Investor’s obligations under this Section 4.5.

An indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the reasonably incurred fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. It is understood and agreed that the Indemnifying Party shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Parties and that all such fees and expenses shall be reimbursed as they are incurred. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of liability to the indemnified party under this Section 4.5to the extent the indemnifying party is so prejudiced, but the omission to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 4.5.

21

The relative fault of the indemnifying party and of the indemnified party shall be determined 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 party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.5(b) 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 paragraph. Notwithstanding the provisions of this Section 4.5(d), (i) the Investor as an indemnifying party shall not be required to contribute any amount in excess of the amount that the Investor has otherwise been, or would otherwise be, required to pay pursuant to this Section 4.5(d) by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to a contribution from any Person who was not guilty of such fraudulent misrepresentation.

(a)    make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times so long as the Company remains subject to the periodic reporting requirements under Sections 13 or 15(d) of the Exchange Act;

(b)    file with the Commission in a timely manner all reports and other documents required of the Company under all U.S. Securities Laws;

(c)    promptly furnish to the Investor upon request (i) a written statement by the Company that it has complied with the reporting requirements of all U.S. Securities Laws or, at any time after so qualified, that it qualifies as a registrant whose securities may be resold pursuant to a Shelf Registration Statement, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents as may be filed by the Company with the Commission, and (iii) such other information as may be reasonably requested in availing the Investor of any rule or regulation of the Commission, that permits the selling of any such securities without Registration or pursuant to a Shelf Registration Statement; and

22

(d)    if the Company is no longer subject to the periodic reporting requirements under Section 13 or 15(d) of the Exchange Act, prepare and furnish to the Investor and make publicly available in accordance with Rule 144(c) such information as is required for the Investor to sell shares under Rule 144, and take such further action as any holder of the Investor shares may reasonably request to the extent required from time to time to enable such Person to sell the shares without registration under the Securities Act within the limitation of the exemptions provided by Rule 144.

Section 4.7    Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the approval of the Investor, enter into any agreement with any holder or prospective holder of any Securities that would (i) grant such holder or prospective holder any registration rights more favorable to such holder or prospective holder than those rights granted pursuant to this ARTICLE IV, (ii) allow such holder or prospective holder to demand Registration of their securities, unless under the terms of such agreement, such holder or prospective holder may demand such Securities in any such Registration only to the extent that the demand of such securities will not reduce the amount of the Registrable Securities of the Investor that are demanded or (iii) allow such holder or prospective holder to include such securities in any Registration filed under Section 4.1(d), Section 4.1(e) or Section 4.2, unless under the terms of such agreement such holder or prospective holder may include such Securities in any such Registration only to the extent that the inclusion of such securities will not reduce the amount of the Registrable Securities of the Investor that are included.

Section 4.8    Termination of the Investor’s Registration Rights. The right of the Investor to request Registration or inclusion of Registrable Securities in any Registration pursuant to Section 4.1 or Section 4.2 shall terminate when all of the Investor’s Registrable Securities may be sold without restriction or limitation under Rule 144.

Section 4.9    Assignment of the Investor’s Registration Rights. The rights and obligations of the Investor under this ARTICLE IV may be assigned by the Investor to any transferee or assignee of any of the Investor’s Registrable Securities; provided that: (a) the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the Securities with respect to which such registration rights are being assigned and (b) such transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of this ARTICLE IV.

In the event the Company has not issued and sold such New Securities within such sixty (60) Trading Day period, the Company shall not thereafter offer, issue or sell such New Securities without first offering such New Securities to the Investor in the manner provided in this ARTICLE V.

Section 5.5    In the case of the offering of New Securities for a consideration in whole or in part other than cash, including securities acquired in exchange therefor, the consideration other than cash shall be deemed to be the fair value thereof as determined in good faith by the Board; provided, however, that such fair value as determined by the Board shall not exceed the aggregate market price of the New Securities being offered as of the date the Board authorizes the offering of such New Securities.

Section 7.4    Reserved.

Section 7.5    Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to principles of conflict of laws thereunder other than New York General Obligations Law Section 5-1401.

Section 7.6    Dispute Resolution.

(a)    Any and all disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision) shall be referred to and finally resolved by arbitration under the Rules of Arbitration of the London Court of International Arbitration (“LCIA Rules”) by one or more arbitrators appointed in accordance with the LCIA Rules (the “Arbitral Tribunal”);

(b)    The arbitration shall be conducted by a sole arbitrator unless either party objects, in which case the arbitration shall be conducted by a panel of three arbitrators. Where the

29

arbitration is to be conducted by a sole arbitrator, the parties shall attempt to agree upon the selection of the sole arbitrator. If they cannot reach agreement within 30 days from the commencement of the arbitration, the sole arbitrator shall be appointed by the Court of the LCIA (the “LCIA Court”) in accordance with the LCIA Rules. Where the arbitration is to be conducted by a panel of three arbitrators, each party shall nominate one arbitrator and the two party-nominated arbitrators shall then select the chairman of the Arbitral Tribunal.

(c)    The place of arbitration shall be London;

(d)    The language of the arbitration shall be English;

(e)    Each arbitrator shall be licensed to practice law in New York;

(i)    Recognition and enforcement of any award rendered by the Arbitral Tribunal may be sought in any court of competent jurisdiction.

Section 7.7    Severability. If any provision of this Agreement is found to be invalid or unenforceable, then such provision shall be construed, to the extent feasible, so as to render the provision enforceable and to provide for the consummation of the transactions contemplated hereby on substantially the same terms as originally set forth herein, and if no feasible interpretation would save such provision, it shall be severed from the remainder of this Agreement, which shall remain in full force and effect unless the severed provision is essential to the rights or benefits intended by the parties. In such event, the parties shall use commercially reasonable efforts to negotiate, in good faith, a substitute, valid and enforceable provision or agreement, which most nearly effects the parties’ intent in entering into this Agreement.

Section 7.8    No Third Party Beneficiaries.

Section 7.10    Construction. Each of the parties has participated in the drafting and negotiation of this Agreement.

Section 7.11    Counterparts. This Agreement may be executed in one or more identical counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other parties. A facsimile or “PDF” signature shall be considered due execution and shall be binding upon the signatory thereto with the same force and effect as if the signature were an original.

Section 7.12    Aggregation of Shares. All Securities held or acquired by the Investor shall be aggregated together for the purpose of determining the availability of any rights of the Investor under this Agreement.

Section 7.13    Investor Rights Agreement to Control. If, and to the extent that, there are inconsistencies between the provisions of this Agreement and those of the Company Certificates and the Company Bylaws, the terms of this Agreement shall control to the extent permissible under any applicable Law. The parties agree to take all actions necessary or advisable, as promptly as practicable after the discovery of such inconsistency, to amend the Company Certificates and the Company Bylaws so as to eliminate such inconsistency to the extent permissible under any applicable Law.

Section 7.14    Specific Performance. The parties hereto acknowledge and agree irreparable harm may occur for which money damages would not be an adequate remedy in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that, in addition to any other remedies at law or in equity, the parties to this Agreement shall be entitled to injunction to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement without posting any bond or other undertaking.

Any amendment or waiver effected in accordance with this Section 7.15 shall be binding upon the Company and the Investor and their

31

respective assigns. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring.

Section 7.16    Expenses. Except as expressly provided herein, each party will bear its own costs and expenses incurred by it or on its behalf in connection with the Transaction Documents and the transactions contemplated thereby.

Section 7.17    Public Announcements. Without limiting any other provision of this Agreement, the parties hereto, to the extent permitted by applicable Law, will consult with each other before issuance, and provide each other the opportunity to review, comment upon and concur with, and use all reasonable efforts to agree on any press release or public statement with respect to this Agreement and the other Transaction Documents and the transactions contemplated hereby and thereby, and will not (to the extent practicable) issue any such press release or make any such public statement prior to such consultation and agreement, except as may be required by Law or any listing agreement with or requirement of the Nasdaq or any other applicable securities exchange, provided that the disclosing party shall, to the extent permitted by applicable Law or any listing agreement with or requirement of the Nasdaq or any other applicable securities exchange and if reasonably practicable, inform the other parties about the disclosure to be made pursuant to such requirements prior to the disclosure.

(ii)    immediately after the Investor exercises the Warrant in full, the Company will be a “controlled company” within the meaning of the Nasdaq Listing Rules and, so long as it remains a controlled company, the Company shall be exempted from Rule 5615 of the Nasdaq Listing Rules of Rules 5605(b), (d) and (e) (except for the requirements of subsection (b)(2) which pertain to executive sessions of Independent Directors) of the Nasdaq Listing Rules,

(iii)    provided, in each case, unless prohibited by applicable Law and stock exchange requirements, the Investor shall have the right to nominate all of the Investor Directors as non-Independent Directors serving on the Board.

Section 2.4.    Grant of Irrevocable Proxy; Appointment of Proxy.

(a)    Each Founder and the Investor further agrees not to take any other actions as a stockholder of the Company or in any other capacity intended to or reasonably likely to, directly or indirectly, circumvent, avoid or nullify the voting arrangements required by this Article II.

(b)    Each Founder hereby irrevocably appoints the Investor and any designee thereof as its proxy and attorney-in-fact (with full power of substitution), to vote or cause to be voted (including by proxy, if applicable) such Founder’s Founder Shares (i) in accordance with Section 2.1 above, and (ii) subject to and commencing upon the Closing, in accordance with Section 2.3(a)(iii) above, in each case at any annual or special meeting of the shareholders of the Company, however called, including any adjournment or postponement thereof, at which any of the matters described in Section 2.1 or Section 2.3(a)(iii) above is to be considered. Each Founder represents that all proxies, powers of attorney, instructions or other requests given by such Founder prior to the execution of this Agreement in respect of the voting of such Founder’s Founder Shares, if any, are not irrevocable and each Founder hereby revokes any and all previous proxies, powers of attorney, instructions or other requests with respect to such Founder’s Founder Shares. Each Founder shall take such further action or execute such other instruments as may be necessary to effectuate the intent of this proxy.

(c)    Each Founder affirms that the irrevocable proxy set forth in this Section 2.4 is given in connection with the execution of the Share Purchase Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Founder under this

9

Agreement. Each Founder further affirms that the irrevocable proxy is coupled with an interest and, except as set forth in this Section 2.4, is intended to be irrevocable; provided, that such proxy shall be automatically terminated in respect of the matters described in Section 2.1 at the Expiration Time. If for any reason the proxy granted herein is not irrevocable, then each Shareholder agrees to vote such Shareholder’s Securities in accordance with Section 2.1 and Section 2.3(a)(iii) above (in the case of the matters described in Section 2.1, prior to the Expiration Time). The parties hereto agree that the foregoing is a voting agreement.

Section 2.5.    Restrictions on Transfers. Each Founder hereby agrees that, from the date hereof until the Expiration Time, such Founder shall not, and shall cause its Affiliates not to, directly or indirectly, (a) Transfer any Founder Shares if such Transfer (x) has, or would reasonably be expected to have, the effect of reducing or limiting such Founder’s economic interest in such Founder Shares or (y) grants a third party the right to vote or direct the voting of such Founder Shares, (b) deposit any Founder Shares into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect thereto that is inconsistent with this Agreement, (c) convert or exchange, or take any action which would result in the conversion or exchange of, any Founder Shares, (d) knowingly take any action that would make any representation or warranty of such Founder set forth in this Agreement untrue or incorrect or have the effect of preventing, disabling, or delaying such Founder from performing any of its obligations under this Agreement, or (e) agree (whether or not in writing) to take any of the actions referred to in the foregoing clauses (a), (b), (c) or (d).

ARTICLE III

RIGHT OF FIRST REFUSAL

Section 3.1.    Transfer Notice. Subject to Section 3.3, if at any time upon and after the Closing (a) any of the Founders (the “Selling Shareholder”) proposes to Transfer any Securities of the Company held by such Selling Shareholder, in whole or in part, to one or more Third Parties; or (b) any Securities held directly or indirectly by the Selling Shareholder are Transferred involuntarily pursuant to divorce, legal separation, bankruptcy or other proceedings, death or any other involuntary Transfer (collectively, “Involuntary Transfers”), then such Selling Shareholder (or its, his or her executor) shall first comply with the provisions of Section 3.2. Notwithstanding the foregoing, a Transfer resulting from the death of a Founder shall not be deemed to be an Involuntary Transfer if the transferee, upon request of any party hereto or receiving a Purchase Notice, executes the written agreement contemplated in the proviso at the end of Section 3.3, in which case such transferee shall be deemed to be a Permitted Transferee.

Section 3.2.    Right of First Refusal.

(a)    Prior to making or accepting an offer to Transfer any of its Securities to any third party, a Selling Shareholder (or its, his or her executor) shall give the Investor a written notice of its intention to make such Transfer (the “Transfer Notice”), which shall include (i) a description (including the class and the total number) of Securities to be Transferred (the “Offered Shares”); (ii) the identity of the prospective transferee(s); and (iii) the proposed offer price per Offered Shares (the “Offer Price”) and the material terms and conditions upon which the proposed Transfer is to be made. The Transfer Notice shall certify that the Transferor has received a firm offer from the prospective bona fide transferee(s) or otherwise believes in good faith that a

10

binding agreement for the Transfer is obtainable on the terms set forth in the Transfer Notice. The Transfer Notice shall also include a copy of any written proposal, term sheet or letter of intent or other agreement relating to the proposed Transfer. The Selling Shareholder and the Investor shall thereafter comply with the following provisions of Section 3.2.

(b)    The Investor shall be granted the right of first refusal by the terms of the Transfer Notice, which the Investor can exercise upon giving written notice to the Selling Shareholder (the “Purchase Notice”) within thirty (30) days after its receipt of the Transfer Notice. The Purchase Notice shall specify the maximum number of Offered Shares which the Investor desires to purchase. The Investor will have the right to purchase all of the Offered Shares, on the same terms and conditions as set forth in the Transfer Notice, subject to Section 3.2(d) and (e).

(c)    In the event that the Transfer in question is an Involuntary Transfer, the price per share shall be the greater of the original purchase price paid by the Selling Shareholder for such Offered Shares (appropriately adjusted for share splits, share dividends, combinations and the like) and the fair market value of such Offered Shares, which, if the Common Stock is at the relevant time listed on an established U.S. national or non-U.S. securities exchange or reported through or an established over-the-counter trading system, shall be determined with reference to the price per share of Common Stock based on the trailing average VWAP over the preceding ten (10) consecutive Trading Days prior to the effective date of the Involuntary Transfer.

(d)    In the event the consideration for the Offered Shares specified in a Transfer Notice is payable in property other than cash and the Selling Shareholder and the Investor cannot agree on the cash value of such property within ten (10) days after the Investor’s receipt of the Transfer Notice, the value of such property shall be determined by an appraiser of recognized standing selected jointly by the Selling Shareholder on one hand and the Investor on the other hand. If they cannot agree on an appraiser within twenty (20) days after receipt of the Transfer Notice by the Investor, within a further five (5)-day period, the Selling Shareholder on one hand and the Investor on the other hand shall each select an appraiser of recognized standing and the two appraisers shall designate a third appraiser of recognized standing to determine the value of such property. The value of such property shall be determined by the appraiser selected pursuant to this Section within one month from its appointment, and such determination shall be final and binding on the Selling Shareholder and the Investor. The cost of such appraisal shall be shared equally by the Selling Shareholder on one hand and the Investor on the other hand. If the thirty (30) day period as specified in Section 3.2(b) has expired but for the determination of the value of the consideration for the Offered Shares offered by the Selling Shareholder, then such thirty (30) day period shall be extended to the fifth (5th) Business Day after such valuation shall have been determined to be final and binding pursuant to this Section.

(e)    Notwithstanding anything to the contrary in this Section 3.2, in the event that a Investor elects to purchase any Offered Shares pursuant to its right of first refusal hereunder and the Common Stock is at the relevant time listed on an established U.S. national or non-U.S. securities exchange or reported through or an established over-the-counter trading system, the Offer Price payable by the Investor shall be the lower of (i) the Offer Price as set forth in the Transfer Notice, subject to Section 3.2(d), and (ii) the trailing average VWAP over the preceding ten (10) consecutive Trading Days immediately prior to the delivery of the Purchase Notice by the Investor to the Selling Shareholder in respect of such Offered Shares.

11

(f)    To the extent that the Investor has not exercised their rights to purchase the Offered Shares subject to the Transfer Notice, the Selling Shareholder shall have a period of sixty (60) days from the expiration of such rights in which to sell any remaining Offered Shares, upon terms and conditions (including, without limitation, the purchase price) no more favorable to the purchaser than those specified in the Transfer Notice, to the third party transferee(s) identified in the Transfer Notice and the Offered Shares that are sold shall not be subject to the terms and provisions of this Agreement and all proxies granted hereunder shall terminate but solely with respect to the Offered Shares that have been sold. In the event a Selling Shareholder does not consummate the sale or disposition of the Offered Shares within the sixty (60) day period from the expiration of these rights, the Investor’ right of first refusal shall continue to be applicable to any subsequent disposition of any Common Stock by any Selling Shareholder. Furthermore, the exercise or non-exercise by the Investor to purchase Offered Shares by the Selling Shareholder shall not adversely affect the Investor’s rights to make subsequent purchases from any Selling Shareholder. Any proposed Transfer on terms and conditions significantly different than those described in the Transfer Notice, as well as any subsequent proposed Transfer of any of the Offered Shares by a Selling Shareholder shall again be subject to the right of first refusal of the Investor as provided under this Section 3.2 and shall require compliance by the relevant Selling Shareholder with the procedures described in this Agreement.

Section 3.3.    Exempt Transfers. Subject to this Section 3.3, none of the restrictions and/or requirements contained in Section 3.1 and Section 3.2 with respect to Transfers of Securities shall apply to any:

(a)    Transfer of the Securities, directly or indirectly, by the Founder to the Founder’s ancestors, descendants, immediate family members, or spouse or to trusts for the benefit of such persons or parties or to the entities in which the Founder and/or his ancestors, descendants, immediate family members, or spouse holds 100% of the equity or beneficial interests;

(b)    Transfer of Securities by a Founder for estate planning purposes to a limited partnership, trust, association or other entity that is wholly-owned or controlled by such Founder;

(c)    Transfers of Securities by the Investor to any of its Affiliates (such transfers contemplated under clause (a) and clause (b) above and this clause (c) a “Permitted Transfer” and such transferees a “Permitted Transferee”);

(d)    issuance of Common Stock upon conversion of the Preferred Stock or exercise of the Warrant; or

(e)    bona fide sale of Securities by a Founder or the Investor to a Third Party of less than 3% of the Securities held by such Founder or the Investor, as applicable, during any three month period;

provided, that each Permitted Transferee shall, as a condition to the effectiveness of any such Permitted Transfer, furnish the parties hereto with a written agreement to be bound by and comply with this Agreement, including, without limitation, all provisions of ARTICLE II and ARTICLE III, as if such transferee(s) were the transferor hereunder, as well as the terms of the agreement pursuant to which such Offered Shares were issued; provided, further, that the transferor shall remain liable for any breach by such Permitted Transferee of any provision hereunder.

Section 5.11.    Calculation of Investor Shares. In calculating the Investor’s ownership of Common Stock at any given time and from time to time for purposes of determining the availability of any Investor rights under this Agreement, all Securities held or acquired by the Investor and/or its Affiliates shall be aggregated together and any Securities other than Common Stock which are ultimately convertible or exercisable into, or exchangeable for, Common Stock rights will be deemed to have been convertible or exercisable into Common Stock (regardless of whether at such time conversion or exercise is permissible under the terms of such Security).

Section 5.12.    Specific Performance. Except as otherwise expressly provided herein, any and all remedies provided herein will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by the parties hereto in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Investor, on the one hand, and each of the Founders, on the other hand, shall be entitled to seek an injunction or injunctions, specific performance and

18

other equitable remedies to prevent breaches of this Agreement by the other (as applicable) and to seek to enforce specifically the terms and provisions of this Agreement and to thereafter cause the transactions contemplated by this Agreement to be consummated on the terms and subject to the conditions thereto set forth in this Agreement. The foregoing rights are in addition to and without limitation of any other remedy to which the parties may be entitled at law or in equity. The parties further agree not to assert that a remedy of specific performance is unenforceable, invalid, contrary to law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy. Each of the parties hereto hereby waives (i) any defenses in any action for specific performance, including the defense that a remedy at law would be adequate and (ii) any requirement under any Law to post a bond or other security as a prerequisite to obtaining equitable relief.

Section 5.13.    Amendment; Waiver. Any provision of this Agreement may be amended, modified or supplemented only by a written instrument duly executed by all the parties hereto. The observance of any provision in this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only by the written consent of the party against whom such waiver is to be effective. Any amendment or waiver effected in accordance with this Section 5.13 shall be binding upon the Investor, the Founders and their respective assigns. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring.

Section 5.14.    Expenses. Except as expressly provided herein, each party will bear its own costs and expenses incurred by it or on its behalf in connection with the Transaction Documents and the transactions contemplated thereby.

Section 5.15.    Additional Securities. Each of the Founders and Investor covenants and agrees to promptly (and in any event within 48 hours) notify the other parties of any new Securities of the Company with respect to which beneficial ownership is acquired by such party or their respective Affiliates, including, without limitation, by purchase, as a result of a share dividend, share split, recapitalization, combination, reclassification, exchange or change of such shares, or upon exercise or conversion of any securities of the Company, if any, after the date hereof. Any such Securities shall automatically become subject to the terms of this Agreement and Schedule A hereto shall be deemed amended accordingly.

Section 5.16.    Disclosure. Unless required by Law, any stock exchange rules, or upon request of any Governmental Authority or stock exchange, each of the Parties shall not, and shall cause their respective Affiliates not to, make any press release, public announcement or other public communication that criticizes or disparages this Agreement or the Share Purchase Agreement or the transactions contemplated hereby or thereby, without the prior written consent of the other parties. Each party (a) consents to and authorizes the publication and disclosure by any party of the other parties’ identity and ownership of the Securities and the existence and terms of this Agreement (including, for the avoidance of doubt, the disclosure of this Agreement) and any other information, in each case, that a party reasonably determines in its good faith judgment is required to be disclosed by Law or any stock exchange rules in any press release,

19

any other disclosure document in connection with the Share Purchase Agreement or this Agreement and any filings with or notices to any Governmental Authority or stock exchange in connection with the Share Purchase Agreement or this Agreement (or the transactions contemplated thereby or hereby) and (b) agrees promptly to give to any party any information they may reasonably request for the preparation of any such documents.

“UCC” means the Uniform Commercial Code as in effect from time to time in the State of Delaware or, when the laws of any other state govern the method or manner of the perfection or enforcement of any security interest in any of the Pledged Shares, the Uniform Commercial Code as in effect from time to time in such state.

2. Pledge. Each Pledgor hereby pledges, assigns and grants to the Secured Party, and hereby creates a continuing first priority lien and security interest in favor of the Secured Party in and to such Pledgor’s Pledged Shares.

3. Secured Obligation. The Pledged Shares secure the obligation of the Company to effect the Stockholder Approval under the Stock Purchase Agreement, the Investor Rights Agreement and the Certificate of Designation for the Series B Redeemable Preferred Stock.

4. UCC Filings. Each Pledgor hereby irrevocably authorizes the Secured Party at any time and from time to time to file in any relevant jurisdiction any financing statements and amendments thereto that contain the information required by Article 9 of the UCC of each applicable jurisdiction for the filing of any financing statement or amendment relating to the Pledged Shares, without the signature of the Pledgor where permitted by law. Each Pledgor shall execute all such applications and other instruments as may be reasonably required by Secured Party in connection with securing the Pledged Shares or perfecting any Lien (including any UCC filings) on the Pledged Shares.

5. Representations and Warranties. Each Pledgor represents and warrants as follows:

Upon Stockholder Approval, (a) all of Pledgors’ obligations under this Agreement will terminate, (b) all Liens and security interests granted under this Agreement shall be released, (c) the Pledged Shares and any other property then held as part of the collateral in accordance with the provisions of this Agreement (including any monies at the time held by the Secured Party hereunder) shall be returned to the Pledgors or to such other Person as shall be legally entitled thereto, (d) any proxies granted pursuant to this Agreement shall automatically terminate without any further action by any person, and (e) all representations and warranties of Pledgor contained in this Agreement shall terminate.

15. Possession of Pledged Shares. Beyond the exercise of reasonable care to assure the safe custody of the Pledged Shares in the physical possession of Secured Party pursuant hereto, neither Secured Party nor any nominee of Secured Party shall have any duty or liability to collect any sums due in respect thereof or to protect, preserve or exercise any rights pertaining thereto (including any duty to ascertain or take action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to the Pledged Shares and any duty to take any necessary steps to preserve rights against any parties with respect to the Pledged Shares), and shall be relieved of all responsibility for the Pledged Shares upon surrendering them to Pledgor.

condition of the Company and of all other circumstances bearing upon the risk relating to failure to obtain stockholder approval of the matters required prior to the Pledge Effective Time, and Secured Party shall have no duty to advise Pledgor of information known to Secured Party regarding such condition or any such circumstance. Secured Party shall have no duty to inquire into the powers of any company or their respective officers, directors or agents thereof acting or purporting to act on their behalf except where reliance by Secured Party on the direction of a Person purporting to act on behalf of any company would amount to gross negligence or willful misconduct.

17. Taxes and Expenses. Each Pledgor will, upon demand, pay to Secured Party, (a) any taxes (excluding income taxes, franchise taxes or other taxes levied on gross earnings, profits or the like of Secured Party) due and payable or ruled due and payable by any federal or state authority in respect of this Agreement, together with interest and penalties, if any, and (b) all reasonable expenses, including the reasonable fees and expenses of counsel, of Secured Party to the extent (i) incurred by the Secured Party due to such Pledgor’s failure to perform or observe any provisions of this Agreement and (ii) the incurrence of such expenses are necessary for the Secured Party to exercise any of its rights or enforce any of such Pledgor’s obligations under this Agreement.
