Subject to the terms of this Agreement, the Purchaser will, and will cause Acquireco to:

At the Effective Time, as a result of the Merger and without any action on the part of the Purchaser, Acquireco, the Company or the holder of any capital stock or shares, as applicable, of the Purchaser, Acquireco or the Company:

and promptly deliver written notice to the other Party setting out full particulars thereof.

provided, however, that subject to the terms of this Agreement, the Company shall not be required to cooperate with the Purchaser with respect to any of the foregoing that relates to a Company Acquisition Proposal, a Company Superior Proposal or a Company Change of Recommendation.

and promptly deliver written notice to the other Party setting out full particulars thereof.

including, engaging the services of a firm acceptable to the Purchaser (acting reasonably) as proxy solicitation agent to solicit proxies in favour of the approval of the Merger Resolution;

together with their record addresses and their respective holdings of shares of Company Stock, Company Options, Company RSUs and Company Warrants, as applicable;

provided, however, that the foregoing shall be subject to the Company’s and Purchaser’s overriding obligation to make any disclosure or filing required by applicable Laws or stock exchange rules.

provided, however, that the foregoing shall be subject to the Company’s overriding obligation to make any disclosure or filing required by applicable Laws or stock exchange rules.

At the Effective Time, each outstanding Company Option, whether vested or unvested, shall, automatically and without any action on the part of the holder thereof, be cancelled and converted into the right to receive (without interest), as soon as reasonably practicable following the Effective Time, the Common Stock Consideration in respect of each share of Company Common Stock which would have been issued upon the net exercise of the Company Option calculated as follows: the number of shares of Company Common Stock otherwise deliverable pursuant to the Company Option shall be reduced by the number of such shares having a Fair Market Value on the Closing Date equal to the exercise price. Any Company Option that has an exercise price per share that is greater than or equal to the Fair Market Value on the Closing Date shall be cancelled at the Effective Time for no consideration or payment.

Promptly following the Effective Time, the Purchaser shall, in compliance with all applicable Laws, deliver or cause the Surviving Corporation to deliver, to each holder of Company Options at the Effective Time, the Common Stock Consideration, if any, to which such holder is entitled in respect of his or her Company Options. To the extent the delivery of such Common Stock Consideration constitutes a payment of wages, (i) the Purchaser shall cause the payment to be processed by the Surviving Corporation through its payroll system, (ii) the Common Stock Consideration deliverable shall be reduced by a number of Purchaser Shares having a Fair Market Value equal to all required tax withholdings, and (iii) the Purchaser shall cause the Surviving Corporation to remit timely such required withholdings in cash to the relevant taxing authorities.

At the Effective Time, each outstanding Company RSU, whether vested or unvested, shall, automatically and without any required action on the part of the holder thereof, be cancelled and converted into the right to receive (without interest), as soon as reasonably practicable following the Effective Time, the Common Stock Consideration in respect of each share of Company Common Stock underlying such Company RSU, without interest.

Promptly following the Effective Time, the Purchaser shall, in compliance with all applicable Laws, deliver or cause the Surviving Corporation to deliver, to each holder of Company RSUs at the Effective Time, the Common Stock Consideration to which such holder is entitled in respect of his or her Company RSUs. To the extent the delivery of such Common Stock Consideration constitutes a payment of wages, (i) the Purchaser shall cause the payment to be processed by the Surviving Corporation through its payroll system, (ii) the Common Stock Consideration deliverable shall be reduced by a number of Purchaser Shares having a Fair Market Value equal to all required tax withholdings, and (iii) the Purchaser shall cause the Surviving Corporation to remit timely such required withholdings in cash to the relevant taxing authorities.

The Company shall, to the extent permitted by the Company Warrant, require that the holder exercise the Company Warrant prior to the Closing Date, and if the Company Warrant is not exercised, that the Company Warrant shall terminate. If the Company Warrant does not permit the treatment outlined in the foregoing sentence, then the applicable Company Warrants shall in accordance with their terms be exchanged for warrants of the Purchaser having economically equivalent terms in accordance with the terms of the Company Warrants, such that the holder of a Company Warrant shall be entitled to receive, in lieu of shares of Company Common Stock to which such holder was theretofore entitled upon such exercise and for the consideration payable therefor, the number of Purchaser Shares which the holder would have been entitled to receive as a result of the transactions contemplated by the Merger if, immediately prior to the Closing Date, such holder had been the registered holder of the number of shares of Company Common Stock to which such holder would have been entitled if such holder had exercised such holder’s Company Warrants immediately prior to the Effective Time.

The Purchaser will, following receipt by the Company of the Regulatory Approvals, ensure that on the Closing Date the Depositary has been provided with Purchaser Shares and Purchaser Preferred Shares in escrow to satisfy the aggregate Merger Consideration payable to Company Stockholders pursuant to the Merger (other than payments to Company Preferred Stockholders exercising dissenter’s rights and who have not withdrawn their notice of exercise).
