ARTICLE I

EQUITYHOLDER SUPPORT; COVENANTS

Section 1.1 No Pre-Closing Transfer. During the period commencing on the date hereof and ending on the earliest to occur of (a) the Effective Time, and (b) such date and time as the Business Combination Agreement shall be terminated in accordance with the terms thereof (the earlier of clauses (a) and (b), the “Expiration Time”), the Equityholder shall not (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, file (or participate in the filing of) a registration statement with the SEC (other than the Proxy Statement/Registration Statement) or establish or increase a put equivalent position or liquidate or decrease a call equivalent position, with respect to any Subject Units owned by the Equityholder, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Subject Units owned by the Equityholder or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii) (clauses (i) to (iii) collectively, a “Transfer’’).

Section 1.2 New Units. In the event that, during the period commencing on the date hereof and ending at the Expiration Time, (a) any Subject Units are issued to the Equityholder after the date of this Agreement pursuant to any unit distribution, unit split, recapitalization, reclassification, combination or exchange of Subject Units or otherwise, (b) an Equityholder purchases or otherwise acquires (including by way of tender offer) beneficial ownership of any Subject Units or (c) an Equityholder acquires (including by way of tender offer) the right to vote or share in the voting of any Subject Units (collectively, the “New Securities”), then such New Securities acquired (including by way of tender offer) or purchased by the Equityholder shall be subject to the terms of this Agreement to the same extent as if they constituted the Subject Units owned by the Equityholder as of the date hereof.

ARTICLE II

EQUITYHOLDER LOCK-UP; COVENANTS

Section 2.1 Lock-up Restriction. The Equityholder 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) until seven (7) days after the Closing (the “Lock-Up Period’’).

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 individual, Transfers by virtue of laws of descent and distribution upon death of the individual;

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

(c) 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;

(d) 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 l 3F, 13G or 130/A) during the Lock-Up Period;

(e) transactions in the event of completion of a liquidation, merger, consolidation, 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; and

(f) transactions to satisfy any U.S. federal, state, or local income tax obligations of the Equityholder 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 hereof, and such change prevents the Merger from qualifying as a transfer to a corporation controlled by transferors under Section 351 of the Code (and the Merger 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;

provided, however, that in the case of clauses (a) through (c), these permitted transferees must enter into a written agreement, in substantially the form of this Agreement, 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 term shall have the following meaning: “Acquiror Securities” shall mean any Acquiror Common Shares held by the Equityholder at Closing, any Acquiror Common Shares issuable upon the exercise of options to purchase Acquiror Common Shares held by the Equityholder at Closing, or any securities convertible into or exercisable or exchangeable for Acquiror Common Shares held by the Equityholder at Closing (in each case, after giving effect to the Transactions and which, for the avoidance of doubt, shall include the Acquiror Common Shares issued or issuable at Closing).
