ARTICLE 1

AMENDMENTS TO THE MERGER AGREEMENT

Section 1.1 Amendment to Section 2.1(a)(iii) of the Merger Agreement. Section 2.1(a)(iii) of the Merger Agreement is hereby amended by deleting Section 2.1(a)(iii) of the Merger Agreement and replacing it in its entirety with the following:

(iii) Company Warrants. Immediately prior to the Effective Time, (x) the Company shall cause each Company Warrant (other than the Finback Warrant) that is issued and outstanding immediately prior to the Effective Time to be either exercised in full on a cash or cashless basis or terminated without exercise and (y) (A) the Company shall cause the portion of the Finback Warrant that is vested as of immediately prior to the Effective Time to be either exercised in full on a cash or cashless basis or terminated without exercise and (B) the portion of the Finback Warrant that is unvested as of immediately prior to the Effective Time (such portion, the “Unvested Finback Warrant”) shall be automatically, without any action on the part of Parent, the Company or the Company Warrant holder, converted into a warrant (the “Parent Finback Warrant”) to acquire shares of Parent Common Stock in accordance with this Section 2.1(a)(iii), in each case, in accordance with the respective terms of such Company Warrant (such actions, collectively the “Company Warrant Settlement”). Such Parent Finback Warrant as so assumed and converted shall continue to have, and shall be subject to, the same terms and conditions as applied to the Finback Warrant immediately prior to the Effective Time. As of the Effective Time, such Parent Finback Warrant as so assumed and converted shall be for that number of shares of Parent Common Stock determined by multiplying the number of shares of the Company Common Stock subject to the unvested portion of such Finback Warrant immediately prior to the Effective Time by the Exchange Ratio, which product shall be rounded down to the nearest whole number of shares, at a per share exercise price determined by dividing the per share exercise price of the Unvested Finback Warrant immediately prior to the Effective Time by the Exchange Ratio, which quotient shall be rounded down to the nearest whole cent. After the Company Warrant Settlement, all of the Company Warrants shall no longer be outstanding and shall cease to exist and each holder of Company Warrants shall thereafter cease to have any rights with respect to such securities except as set forth in this Section 2.1(a)(iii).

Section 1.2 Amendment to Section 2.1 of the Merger Agreement. Section 2.1 of the Merger Agreement is hereby amended by (x) deleting section 2.1(c)(ii) of the Merger Agreement and (y) adding the following provisions as new Section 2.1(d) and Section 2.1(e) of the Merger Agreement and the current Section 2.1(d) of the Merger Agreement (and all references thereto) shall be changed to Section 2.1(f):

(d) Treatment of Company RSUs. At the Effective Time, each outstanding award of Company RSUs, whether vested or unvested, shall, automatically and without any required action on the part of the holder thereof, cease to represent an award of restricted stock units covering shares of Company Common Stock and shall be converted into (i) an award of restricted stock units covering a number of shares of Parent Common Stock determined in accordance with this Section 2.1(d) (each, an “Assumed RSU”), and (ii) the right to receive a number of Earn-Out Shares in accordance with Section 2.8. Each award of Assumed RSUs shall be subject to the same terms and conditions as were applicable to such corresponding award of Company RSUs immediately prior to the Effective Time (including applicable vesting conditions), except to the extent such terms or conditions are rendered inoperative by the Transactions. Each Assumed RSU shall represent an award of restricted stock units of Parent Common Stock at such exercise price, in each case, determined as follows and as set forth in the Allocation Statement: the number of shares of Parent Common Stock awarded pursuant to the Assumed RSU shall be equal to (rounded down to the nearest whole number): (A) the number of shares of Company Common Stock covered by such Company RSU immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio.

(e) Parent Actions. Parent shall take all actions that are necessary for the assumption of the Company Options and the Company RSUs pursuant to this Section 2.1, including the reservation, issuance and listing of Parent Common Stock as necessary to consummate the transactions contemplated by this Section 2.1. If registration of any plan interests in the Stock Plan or other Company Benefit Plans or the shares of Parent Common Stock issuable thereunder is required under the Securities Act, Parent shall file with the SEC on the Closing Date a registration statement on Form S-8 with respect to such interests or Parent Common Stock, and shall use its reasonable best efforts to maintain the effectiveness of such registration statement for so long as the relevant Stock Plan or other Company Benefit Plans, as applicable, remain in effect and such registration of interests therein or the shares of Parent Common Stock issuable thereunder continues to be required.”
