Section 1.3 New Shares. In the event that, during the period commencing on the date hereof and ending at the Expiration Time, (a) any Subject Shares are issued to a Sponsor after the date of this Agreement pursuant to any share dividend, share split, recapitalization, reclassification, combination or exchange of Subject Shares or otherwise, (b) a Sponsor purchases or otherwise acquires (including by way of tender offer) beneficial ownership of any Subject Shares or (c) a Sponsor acquires (including by way of tender offer) the right to vote or share in the voting of any Subject Shares (collectively, the “New Securities”), then such New Securities acquired (including by way of tender offer) or purchased by such Sponsor shall be subject to the terms of this Agreement to the same extent as if they constituted the Subject Shares owned by such Sponsor as of the date hereof.

Section 1.4 Sponsor Agreements. Hereafter until the Expiration Time, each Sponsor hereby unconditionally and irrevocably agrees that, at any meeting of the stockholders of Acquiror (or any adjournment or postponement thereof), and in any action by written resolutions of the stockholders of Acquiror requested by the Board of Directors of Acquiror or otherwise undertaken as contemplated by the Transactions (which written resolutions shall be delivered promptly, and in any event within forty-eight (48) hours, after (x) the Proxy Statement/Registration Statement (as contemplated by the Business Combination Agreement) has been declared effective and has been delivered or otherwise made available (including on the Electronic Data Gathering, Analysis and Retrieval filing system of the SEC) to the stockholders of Acquiror and the shareholders of the Company, and (y) the Company or Acquiror requests such delivery), such Sponsor shall, if a meeting is held, appear at the meeting, in person or by proxy, or otherwise cause all of its, his or her Subject Shares (to the extent such Subject Shares have voting rights and are entitled to vote on or provide consent with respect to such matter) to be counted as present thereat for purposes of establishing a quorum, and such Sponsor shall vote or provide consent (or cause to be voted or consented), in person or by proxy, all of its, his or her Subject Shares (to the extent such Subject Shares have voting rights and are entitled to vote on or provide consent with respect to such matter):

(d) against any proposal, action or agreement that would reasonably be expected to (A) impede, frustrate, prevent or nullify any provision of this Agreement, the Business Combination Agreement, the Business Combination or the other Transactions, (B) result in a breach in any respect of any covenant, representation, warranty or any other obligation or agreement of Acquiror under the Business Combination Agreement, (C) result in any of the conditions set forth in Article IX of the Business Combination Agreement not being fulfilled or (D) change in any manner the dividend policy or capitalization of, including the voting rights of any class of capital stock of, Acquiror.

Each Sponsor hereby agrees that it shall not commit or agree to take any action inconsistent with the foregoing.

Upon the failure of a Sponsor to timely provide its consent or vote its Subject Shares in accordance with this Section 1.4 pursuant to any action by written resolution of the stockholders of Acquiror within the timeframe specified in this Section 1.4 or at any applicable meeting of the stockholders of Acquiror, such Sponsor shall be deemed to have irrevocably granted to, and appointed, Acquiror, and any designee thereof, and each of them individually, as such Sponsor’s proxy and attorney-in-fact (with full power of substitution), for and in such Sponsor’s name, place and stead, to deliver any action by written resolution of the stockholders of Acquiror concerning any of the matters specified in this Section 1.4 or attend any meeting of the stockholders of Acquiror concerning any of the matters specified in this Section 1.4, to include such Subject Shares in any computation for purposes of establishing a quorum at any such meeting of the stockholders of Acquiror and to provide consent or vote such Sponsor’s Subject Shares in any action by written resolution of the stockholders of Acquiror or at any meeting of the stockholders of Acquiror called with respect to any of the matters specified in, and in accordance and consistent with, this Section 1.4. Each Sponsor hereby affirms that the irrevocable proxy is coupled with an interest and may under no circumstances be revoked and that such irrevocable proxy is executed and intended to be irrevocable.

Section 2.1 Lock-up Restriction. Each Sponsor agrees not to, without the prior written consent of the Company and the Board of Directors of Acquiror, Transfer any Acquiror Securities (as defined below), in each case, until the earlier of (a) 180 days after the Closing and (b) the date on which the Closing Price per share of Acquiror Common Shares equals or exceeds $12.50 for any twenty (20) Trading Days within any thirty (30) consecutive Trading Day period; provided, however, that fifty percent (50%) of Acquiror Securities held by such Sponsor shall remain subject to the restriction in the foregoing (a) (the “Lock-Up Period”). “Trading Day” means any day on which Acquiror Common Shares are tradeable on the principal securities exchange or securities market on which Acquiror Common Shares are then traded.

Section 2.2 Exceptions to Lock-up Restriction. The restrictions set out in Section 2.1 above shall not apply to:

(a) in the case of an entity, Transfers to or distributions to any direct or indirect shareholder, partner, member or affiliate of such entity (or to any executive officer or director of such entity or of such entity’s affiliates) or to any investment fund or other entity controlling, controlled by, managing or managed by or under common control or management with such entity or affiliates of such entity (including, for the avoidance of doubt, where the undersigned is a partnership, to its general partner or a successor partnership or fund, or any other funds managed by or under common management as such partnership);

(b) in the case of an individual, Transfers by gift to members of such Sponsor’s immediate family (as defined below) or to a trust, the beneficiary of which is a member of one of such Sponsor’s immediate family, an affiliate of such person or to a charitable organization;

(c) in the case of an individual, Transfers by virtue of laws of descent and distribution upon death of the individual;

(d) in the case of an individual, Transfers pursuant to a qualified domestic relations order or divorce settlement;

(e) in the case of an entity, Transfers by virtue of the laws of the state or jurisdiction of the entity’s organization and the entity’s organizational documents upon dissolution of the entity;

(f) transactions relating to Acquiror Securities acquired in open market transactions after the Closing, provided that no such transaction is required to be, or is, publicly announced (whether on Form 4, Form 5 or otherwise, other than a required filing on Schedule 13F, 13G or 13G/A) during the Lock-Up Period;

(g) the exercise of any options or warrants to purchase Acquiror Securities (which exercises may be effected on a cashless basis to the extent the instruments representing such options or warrants permit exercises on a cashless basis);

(h) Transfers (including forfeitures) (x) to Acquiror to satisfy tax withholding obligations pursuant to equity incentive plans or arrangements of Acquiror or (y) pursuant to escrow arrangement with Acquiror with respect to tax withholding obligations pursuant to the Code;

(i) Transfers to Acquiror pursuant to any contractual arrangement in effect at the Closing that provides for the repurchase by Acquiror or forfeiture of such Sponsor’s Acquiror Securities in connection with the termination of such Sponsor’s service to Acquiror;

(j) the establishment of a trading plan that meets the requirements of Rule 10b5-1(c) under the Exchange Act (a “Trading Plan”); provided, however, that (a) no sales of Acquiror Securities, shall be made by such Sponsor pursuant to such Trading Plan during the Lock-Up Period, and (b)(x) no public announcement or filing shall be made voluntarily regarding such plan during the Lock-Up Period or (y) if any public announcement is required of or voluntarily made by or on behalf of such Sponsor or Acquiror regarding such plan, then such announcement or filing shall include a statement to the effect that no Transfer may be made under such plan during the Lock-Up Period;

(k) transactions in the event of completion of a liquidation, merger, consolidation, stock exchange, reorganization, tender offer or other similar transaction which results in all of Acquiror’s shareholders having the right to exchange their shares of Common Stock of Acquiror for cash, securities or other property;

(l) transactions to satisfy any U.S. federal, state, or local income tax obligations of such Sponsor (or its direct or indirect owners) arising from a change in the U.S. Internal Revenue Code of 1986, as amended (the “Code”), or the U.S. Treasury Regulations promulgated thereunder (the “Regulations”) after the date on which the Business Combination Agreement was executed by the parties, and such change prevents the Business Combination from qualifying as a “reorganization” pursuant to Section 368 of the Code (and the Business Combination does not qualify for similar tax-free treatment pursuant to any successor or other provision of the Code or Regulations taking into account such changes), in each case, solely to the extent necessary to cover any tax liability as a result of the transaction; and

(m) Transfers to an unaffiliated charity or educational institution,

provided, however, that in the case of clauses (a) through (e), these permitted transferees must enter into a written agreement, in substantially the form of this Agreement (it being understood that any references to “immediate family” in the agreement executed by such transferee shall expressly refer only to the immediate family of such Sponsor and not to the immediate family of the transferee), agreeing to be bound by these Transfer restrictions.

Section 2.3 Definitions. For the purposes of this Article II, notwithstanding the other provisions of this Agreement, the following terms shall have the following meanings:

(a) “affiliate” shall have the meaning set forth in Rule 405 under the Securities Act of 1933, as amended.

(b) “immediate family” shall mean a spouse, domestic partner, child, grandchild or other lineal descendant (including by marriage or adoption), father, mother, brother, sister or first cousin of the Sponsor.

(a) Organization; Due Authorization. If such Sponsor is not an individual, it is duly organized, validly existing and in good standing under the Laws of the jurisdiction in which it is incorporated, formed, organized or constituted, and the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby are within such Sponsor’s corporate, limited liability company or organizational powers and have been duly authorized by all necessary corporate, limited liability company or organizational actions on the part of such Sponsor. If such Sponsor is an individual, such Sponsor has full legal capacity, right and authority to execute and deliver this Agreement and to perform his or her obligations hereunder. This Agreement has been duly executed and delivered by such Sponsor and, assuming due authorization, execution and delivery by the other parties to this Agreement, this Agreement constitutes a legally valid and binding obligation of such Sponsor, enforceable against such Sponsor in accordance with the terms hereof (except as enforceability may be limited by bankruptcy Laws, other similar Laws affecting creditors’ rights and general principles of equity affecting the availability of specific performance and other equitable remedies). If this Agreement is being executed in a representative or fiduciary capacity, the Person signing this Agreement has full power and authority to enter into this Agreement on behalf of the applicable Sponsor.

(b) Ownership. Such Sponsor is the record and beneficial owner (as defined in the Securities Act), or nominee of such Persons, of, and has good title to, all of such Sponsor’s Subject Shares as set forth opposite such Sponsor’s name in Schedule I attached hereto, and there exist no Liens or any other limitation or restriction (including any restriction on the right to vote, sell or otherwise dispose of such Subject Shares (other than transfer restrictions under the Securities Act)) affecting any such Subject Shares, other than Liens pursuant to (i) this Agreement, (ii) the Acquiror Governing Documents, (iii) the Business Combination Agreement, (iv) the Sponsor Letter Agreement or (v) any applicable securities Laws. Such Sponsor’s Subject Shares are the only equity securities in Acquiror owned of record or beneficially by such Sponsor on the date of this Agreement, and none of such Sponsor’s Subject Shares are subject to any proxy, voting trust or other agreement or arrangement with respect to the voting of such Subject Shares, except as provided hereunder and under the Sponsor Letter Agreement. Aside from the Subject Shares, such Sponsor does not hold or own any rights to acquire (directly or indirectly) any equity securities of Acquiror or any equity securities convertible into, or which can be exchanged for, equity securities of Acquiror.

(c) No Conflicts. The execution and delivery of this Agreement by such Sponsor does not, and the performance by such Sponsor of his, her or its obligations hereunder will not, (i) if such Sponsor is not an individual, conflict with or result in a violation of the organizational documents of such Sponsor or (ii) require any consent or approval that has not been given or other action that has not been taken by any Person (including under any Contract binding upon such Sponsor or such Sponsor’s Subject Shares), in each case, to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by such Sponsor of his, her or its obligations under this Agreement.

(d) Litigation. There are no Actions pending against such Sponsor, or to the knowledge of such Sponsor threatened against such Sponsor, before (or, in the case of threatened Actions, that would be before) any arbitrator or any Governmental Authority, which in any manner challenges or seeks to prevent, enjoin or materially delay the performance by such Sponsor of its, his or her obligations under this Agreement.

(e) Brokerage Fees. Save as described on Section 5.13 of the Acquiror Disclosure Letter, no broker, finder, investment banker or other Person is entitled to any brokerage fee, finders’ fee or other commission in connection with the Transactions based upon arrangements made by such Sponsor, for which Acquiror or any of its Affiliates may become liable.

(f) Acknowledgment. Such Sponsor understands and acknowledges that each of Acquiror and the Company is entering into the Business Combination Agreement in reliance upon such Sponsor’s execution and delivery of this Agreement.
