(c) The execution and delivery of this Agreement by Parent and Merger Sub, the performance by Parent and Merger Sub of their obligations hereunder and the consummation by Parent and Merger Sub of the transactions contemplated hereby does not and will not result in a violation or breach of, or constitute (with or without notice or lapse of time or both) a default under, or conflict with (i) any provisions of the organizational documents of Parent or Merger Sub or (ii) any judgment, Order, decree, statute, Law, rule or regulation to which Parent or Merger Sub or any of their assets is subject or bound.

Section 4. Tender of the Shares. Unless this Agreement shall have been terminated in accordance with its terms, the Stockholder hereby agrees that he, she or it shall (i) tender the Shares (and deliver any certificates evidencing the Shares or an appropriate affidavit of lost certificate with respect thereto to the extent any of such certificates have been lost, misplaced or destroyed), or cause the Shares to be tendered, into the Offer promptly following the date hereof, and in any event no later than five Business Days prior to the Initial Expiration Time of the Offer, free and clear of all Encumbrances, and (ii) not withdraw the Shares, or cause the Shares to be withdrawn, from the Offer at any time. If the Stockholder acquires Shares after the date hereof, the Stockholder shall (A) tender or cause to be tendered such Shares on or before the fifth Business Day prior to the Initial Expiration Time or, if later, on or before the Business Day after such acquisition but in any event prior to the Expiration Time, and (B) not withdraw such Shares, or cause such Shares to be withdrawn, from the Offer at any time.

Section 5. Transfer of the Shares; Other Actions. Prior to the termination of this Agreement, except as otherwise provided herein (including pursuant to Section 4 hereof), the Stockholder shall not: (i) tender into any tender or exchange offer or otherwise directly or indirectly transfer, assign, sell, gift-over, pledge or otherwise dispose (whether by sale, distribution or otherwise) of, or consent to any of the foregoing (“Transfer”), any Shares or any right or interest therein; (ii) enter into any Contract, option or other arrangement or undertaking with respect to any Transfer of Shares or any other securities of the Company (other than an agreement with the Company whereby all Company Stock Options shall be terminated at the Effective Time or other agreements pursuant to Section 3.07 of the Merger Agreement), or offer to do or consent to any of the foregoing; (iii) grant any proxy or power-of-attorney with respect to any of the Shares in contravention of the obligations of the Stockholder hereunder or the transactions contemplated hereby; (iv) deposit any of the Shares into a voting trust, or enter into a voting agreement or arrangement with respect to any of the Shares in contravention of the obligations of the Stockholder hereunder or the transactions contemplated hereby; or (v) take any other action that would restrict, limit or interfere in any material respect with the performance of the Stockholder’s obligations hereunder or the transactions contemplated hereby. Notwithstanding the foregoing, the preceding sentence shall not prohibit a Transfer of Shares by the Stockholder: (1) to any member of Stockholder’s immediate family, (2) to a trust established for the benefit of Stockholder and/or for the benefit of one or more members of Stockholder’s immediate family, or (3) upon the death of the Stockholder, provided that any Transfer permitted pursuant to (1) to (3) above shall be permitted only if, as a precondition to such transfer, the transferee of such Shares agrees in writing with Parent to be bound by the terms and conditions of this Agreement (a “Permitted Transfer”). Any attempted Transfer of any Shares or any interest therein in violation of this Section 5 shall be null and void ab initio.

Section 6. Covenant to Vote. Prior to termination of this Agreement in accordance with its terms, the Stockholder hereby agrees to vote (or cause to be voted) the Shares (to the extent the Shares are entitled to vote), or to provide (or cause to be provided) a written consent in respect of the Shares, in connection with any meeting of the stockholders of the Company or any action by written consent in lieu of a meeting of stockholders of the Company (i) in favor of approval and adoption of the Merger Agreement, the approval of the Merger and the other transactions contemplated by the Merger Agreement, the other transactions contemplated thereby and any other matter that must be approved by the stockholders of the Company in order for the transactions contemplated by the Merger Agreement to be consummated, (ii) in favor of any adjournment or postponement recommended by Parent with respect to any stockholder meeting with respect to the Merger Agreement and the Merger, and (iii) against any Takeover Proposal or any other action, proposal or agreement that would likely, in Parent’s view, (A) impede, interfere with, materially delay or postpone the Merger and the other transactions contemplated by the Merger Agreement, (B) result in a breach in any respect of any covenant, representation or warranty, or any other obligation or agreement of the Company under the Merger Agreement, (C) change the dividend policy or in any material respect the capitalization of, including the voting rights of any class of equity interests in, the Company, (D) result in any of the conditions set forth in Section 7 or Annex I of the Merger Agreement not being fulfilled or satisfied, or (E) change a majority of the Company Board (other than as directed by Parent or Merger Sub). In the event that a meeting of the stockholders of the Company is held, the Stockholder shall, or shall cause the holder of record on any applicable record date to, appear at such meeting,

in person or by proxy, or otherwise cause the Shares to be counted as present thereat for purposes of establishing a quorum.

Section 7. Proxy and Power of Attorney. The Stockholder, by this Agreement, does hereby constitute and appoint Mark Dennison and Bryce Cooper, or any nominee thereof, with full power of substitution, during and for the term of this Agreement, as the Stockholder’s true and lawful attorney and proxy for and in the Stockholder’s name, place and stead, to vote all the Shares that the Stockholder beneficially owns at the time of such vote, at any annual, special, postponed or adjourned meeting of the stockholders of the Company or to grant a consent or approval in respect of the Shares in any written consent in lieu of such a meeting (and to appear at each such meeting or otherwise cause all of the Shares to be counted as present thereat for purposes of calculating a quorum) in a manner consistent with the provisions of Section 6 hereof, in each case, in the event that (i) the Stockholder fails to comply with its obligations pursuant to Section 6, (ii) any action is commenced, or any Order is entered, which challenges or impairs the enforceability or validity of the obligations of the Stockholder set forth in Section 6, or (iii) otherwise if Parent deems it necessary or advisable. This proxy and power of attorney is a proxy and power coupled with an interest, and the Stockholder declares that it is irrevocable during and for the term of this Agreement and that such proxy shall be revoked automatically, without any notice or other action by any Person, upon termination of this Agreement in accordance with its terms. This proxy is executed and intended to be irrevocable in accordance with the provisions of Section 212 of the DGCL. For the avoidance of doubt, if for any reason this proxy is not irrevocable, the Stockholder shall vote the Shares in accordance with Section 6. For Shares as to which the Stockholder is the beneficial but not the record owner, the Stockholder shall cause the record owner of any such Shares to grant to Parent and Merger Sub a proxy to the same effect as that contained herein.

Section 8. Directors and Officers. Neither the Stockholder nor any Representative of the Stockholder, if any such Person is or becomes during the term of this Agreement a director or officer of the Company, shall be deemed to make any agreement or understanding in this Agreement in such person’s capacity as a director or officer. The Stockholder is entering into this Agreement solely in the Stockholder’s capacity as the owner of the Shares (beneficially and in any other capacity) and nothing herein shall in any way restrict or limit the Stockholder from taking (or omitting to take) any action solely in the Stockholder’s capacity as a director or officer of the Company (including, without limitation, pursuant to Section 6.04 of the Merger Agreement) or otherwise fulfilling the Stockholder’s fiduciary obligations as a director or officer of the Company, in each case subject to the limitations set forth in the Merger Agreement.

Section 9. No Solicitation; Notification. Except as set forth in Section 8 hereof, the Stockholder hereby agrees that during and for the term of this Agreement, the Stockholder shall not, nor shall the Stockholder authorize any of his, her or its Representatives to, directly or indirectly, (a) solicit, initiate, encourage or facilitate the making, submission or announcement of any Takeover Proposal with respect to the Company; (b) furnish any information regarding the Company to any Person in connection with or in response to any Takeover Proposal with respect to the Company; (c) engage in discussions or negotiations with any Person relating to any Takeover Proposal with respect to the Company; (d) approve, endorse or recommend any Takeover Proposal with respect to the Company; (e) make any public statement contrary to the Company Board Recommendation unless the Stockholder reasonably believes after consultation

with legal counsel that such public statement is required under applicable Law; or (f) enter into any Company Acquisition Agreement or enter into any agreement or agreement in principle requiring the Stockholder to abandon, terminate or breach his, her or its obligations hereunder or fail to consummate the transactions contemplated hereby. The Stockholder shall, and shall advise its Representatives to, immediately cease and cause to be terminated all existing communications and negotiations with any Person conducted prior to the execution of this Agreement by or on behalf of the Stockholder or any of his, her or its Representatives with respect to any Takeover Proposal. The Stockholder further acknowledges the obligations of the Company under Section 6.04 of the Merger Agreement and agrees that the Stockholder (solely in the Stockholder’s capacity as such) shall not, and shall not authorize or permit any of its Representatives to act on the Stockholder’s behalf in order to, directly or indirectly, take any action or omit to take any action in contravention of such obligations or to circumvent the purposes of Section 6.04 of the Merger Agreement. The Stockholder agrees to promptly notify Parent of any development occurring after the date hereof that causes, or that would reasonably be expected to cause, any breach of any of the representations and warranties of the Stockholder set forth herein.

Section 10. Waiver of Appraisal and Dissenter’s Rights and Actions. The Stockholder hereby (a) waives and agrees not to exercise any rights of appraisal or rights to dissent from the Merger that the Stockholder may have and (b) agrees not to commence or join in, and agrees to take all actions necessary to opt out of any class in any class action with respect to, any Legal Action, derivative or otherwise, against Parent, Merger Sub, Guarantor, the Company or any of their respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Offer or the Merger, including any Legal Action (i) challenging the validity of, or seeking to enjoin the operation of, any provision of this Agreement or the Merger Agreement or (ii) alleging a breach of any fiduciary duty of any Person in connection with the Merger Agreement or the transactions contemplated thereby.

Section 11. Further Assurances. Subject to the terms and conditions of this Agreement, each of the parties hereto agrees to use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or advisable under applicable Law to consummate and make effective the transactions contemplated hereby. Each party hereto will execute and deliver all such further instruments, documents and agreements and take all such further action as may be necessary or desirable in order to consummate the transactions contemplated hereby. Without limiting the foregoing, Stockholder shall execute and deliver to Parent and any of its designees any additional proxies as may be reasonably necessary to effectuate the intent of the proxy and power of attorney contained in Section 7, including with respect to any Shares acquired after the date hereof, reasonably requested by Parent in furtherance of this Agreement.

Section 12. Adjustments. In the event of any stock dividend, stock split, recapitalization, reclassification, combination or exchange of shares of capital stock or other securities of the Company on, of or affecting the Shares or the like or any other action that would have the effect of changing the Stockholder’s ownership of Company Capital Stock or other securities of the Company, then the terms of this Agreement will apply to the shares of capital

stock or any other equity interest in the Company held by the Stockholder immediately following the effectiveness of such events as though they were Shares hereunder.

Section 13. Termination. This Agreement shall automatically terminate without any notice or other action by any of the parties hereto upon the earliest to occur of: (a) the purchase of all of the Shares pursuant to the Offer in accordance with Section 4 hereof, (b) the Effective Time, (c) the date the Merger Agreement is validly terminated in accordance with its terms, (d) the date of any modification, waiver, change or amendment of the Merger Agreement executed after the date hereof that results in a decrease in the Offer Price or Merger Consideration, and (e) the written agreement of the parties hereto to terminate this Agreement. Termination of this Agreement shall not relieve any party from liability for any willful breach hereof prior to such termination. Sections 10, 14 and 17 hereof shall survive any termination of this Agreement.

Section 14. Expenses. All fees, costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such fees, costs and expenses.

Section 15. Stop Transfer Order. In furtherance of this Agreement, concurrently herewith, the Stockholder shall, and hereby does authorize the Company or its counsel to, notify the Company’s transfer agent that there is a stop transfer order with respect to all of the Shares, other than Permitted Transfers (and that this Agreement places limits on the voting and transfer of the Shares).

Section 16. Disclosure. The Stockholder hereby authorizes Parent, Merger Sub, Guarantor and the Company to publish and disclose in all documents and schedules required to be filed with the Securities and Exchange Commission or similar authority in Canada or elsewhere, and in any press release or other disclosure document that Parent, Merger Sub, Guarantor or the Company reasonably determines to be necessary or desirable in connection with the Offer or Merger and any transactions related to the Offer or Merger, the Stockholder’s identity and ownership of Shares and the nature of the Stockholder’s commitments, arrangements and understandings under this Agreement.

Upon such determination that any term or other provision is invalid, illegal or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the greatest extent possible.

(j) Specific Performance. The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.

Each party agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that the party seeking such injunction, specific performance or other equitable relief has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or equity. In the event that any party seeks an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the terms and provisions of this Agreement, such party shall not be required to provide any bond or other security in connection with any such injunction or other judgment.

(k) Amendment. No amendment, modification or waiver in respect of this Agreement shall be effective against any party unless it shall be in writing and signed by such party.
