Parent and each Stockholder are each sometimes referred to herein individually as a “Party” and collectively as the “Parties.”

WHEREAS, concurrently with or following the execution of this Agreement, the Company, Parent, and Enerflex US Holdings Inc., a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”), have entered, or will enter, into an Agreement and Plan of Merger (as the same may be amended from time to time, the “Merger Agreement”), providing for, among other things, the merger (the “Merger”) of Merger Sub and the Company pursuant to the terms and conditions of the Merger Agreement;

WHEREAS, the Company Board has unanimously (a) determined that it is in the best interests of the Company and its stockholders and declared it advisable to enter into the Merger Agreement; (b) approved the execution, delivery and performance by the Company of the Merger Agreement, the performance by the Company of its covenants and agreements contained therein and the consummation of the transactions contemplated by the Merger Agreement, including the Merger,; (c) resolved to recommend that the Company’s stockholders adopt the Merger Agreement; and (d) directed that the Merger Agreement be submitted to the Company’s stockholders for consideration of the stockholders at the Company Stockholder Meeting.

WHEREAS, in order to induce Parent to enter into the Merger Agreement, each Stockholder is willing to make certain representations, warranties, covenants, and agreements as set forth in this Agreement with respect to the shares of common stock, par value $0.01 per share, of the Company (“Company Common Stock”) of which such Stockholder is the record owner and “beneficial owner” (within the meaning of Rule 13d-3 under the Exchange Act) thereof as of the date hereof (with respect to such Stockholder, the “Original Shares” and, together with any additional shares of Company Common Stock pursuant to Section 6 hereof, the “Shares”); and

WHEREAS, as a condition to its willingness to enter into the Merger Agreement, Parent has required that each Stockholder, and each Stockholder has agreed to, execute and deliver this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants, and agreements set forth below and for other good and valuable consideration, the receipt, sufficiency, and adequacy of which are hereby acknowledged, the Parties hereto, intending to be legally bound, do hereby agree as follows:

As of the date hereof, such Stockholder (including through any of its controlled Affiliates) does not own of record or beneficially any shares of Company Common Stock other than (i) the Original Shares, and (ii) any options, warrants, restricted stock units, performance stock units, or other rights to acquire any additional shares of Company Common Stock or any security exercisable for or convertible into shares of Company Common Stock, set forth on the signature page of this Agreement (collectively, “Options”).

(d) No Conflict. The execution and delivery of this Agreement by such Stockholder does not, and the consummation of the transactions contemplated hereby and the compliance with the provisions hereof will not, conflict with or violate any Law applicable to such Stockholder or result in any breach of or violation of, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration, or cancellation of, or result in the creation of any Lien on any of the Shares pursuant to, any agreement or other instrument or obligation (including organizational documents) binding upon such Stockholder or any of the Shares.

Notwithstanding anything to the contrary in this Agreement, if at any time prior to the Expiration Time a Governmental Entity enters an order restraining, enjoining or otherwise prohibiting any Stockholder or its Affiliates from taking any action pursuant to Section 3(a) and/or Section 3(b) of this Agreement, then (i) the obligations of each Stockholder set forth in Section 3(a) and Section 3(b) of this Agreement, as applicable, shall be of no force and effect for so long as such order is in effect to the extent such order restrains, enjoins or otherwise prohibits such Stockholder or Affiliate from taking any such action, and (ii) each Stockholder shall cause the Shares to not be represented in person or by proxy at any meeting at which a vote of such Stockholder

3

on the Merger Agreement or the transactions contemplated thereby is sought or requested; provided, that neither the Stockholder or any of its controlled Affiliates solicited, knowingly encouraged or participated in any manner with any Governmental Entity in bringing action which resulted in such order.

4. No Voting Trusts or Other Arrangement.

Each Stockholder agrees that except as provided in this Agreement during the term of this Agreement such Stockholder will not deposit any of the Shares in a voting trust, grant any proxies with respect to the Shares, or subject any of the Shares to any arrangement with respect to the voting of the Shares other than agreements entered into with Parent.

5. Transfer and Encumbrance.

Each Stockholder agrees that during the term of this Agreement, such Stockholder will not, directly or indirectly, without the prior written consent of Parent, transfer, sell, offer, exchange, assign, pledge, convey any record or beneficial ownership in or otherwise dispose of (by merger (including by conversion into securities or other consideration), by tendering into any tender or exchange offer, by testamentary disposition, by operation of Law, or otherwise), or encumber (“Transfer”) any of the Shares or enter into any contract, option, or other agreement with respect to, or consent to, a Transfer of, any of the Shares or such Stockholder’s voting or economic interest therein. Any attempted Transfer of Shares or any interest therein in violation of this Section 5 shall be null and void. This Section 5 shall not prohibit a Transfer of the Shares by such Stockholder to an Affiliate of such Stockholder and if such Stockholder is an individual, to any member of such Stockholder’s immediate family, or to a trust for the benefit of such Stockholder or any member of such Stockholder’s immediate family, or upon the death of such Stockholder; provided, that a Transfer referred to in this sentence shall be permitted only if, as a precondition to such Transfer, the transferee agrees in a writing, reasonably satisfactory in form and substance to Parent, to be bound by all of the terms of this Agreement.

6. Additional Shares.

(a) Each Stockholder agrees that all shares of Company Common Stock that such Stockholder purchases, acquires the right to vote, or otherwise acquires record or beneficial ownership of after the execution of this Agreement and prior to the Expiration Time (including by way of any Option exercise) shall be subject to the terms and conditions of this Agreement and shall constitute Shares of such Stockholder for all purposes of this Agreement. In the event of any stock split, stock dividend, merger, reorganization, recapitalization, reclassification, combination, exchange of shares, or the like of the capital stock of the Company affecting the Shares, the terms of this Agreement shall apply to the resulting securities and such resulting securities shall be deemed to be “Shares” for all purposes of this Agreement.

(b) Promptly following the written request of Parent, or upon any Stockholder’s or any of its controlled Affiliates’ acquisition of record or beneficial ownership of

4

additional shares of Company Common Stock or other Company securities after the date hereof, such Stockholder shall send to Parent a written notice setting forth the number of Shares owned of record and beneficially by such Stockholder or any of its controlled Affiliates and indicating the capacity in which such Shares are owned. Each Stockholder agrees to cause any of its controlled Affiliates that acquires any shares of Company Common Stock or other Company securities on or after the date hereof to execute an agreement in a form reasonably acceptable to Parent to be bound with respect to this Agreement with respect to such shares to the same extent such shares would be subject to this Agreement had they been acquired by such Stockholder, and such shares or other Company securities shall be deemed as Shares for all purposes hereunder.
