Seller hereby waives the redemption rights (“Redemption Rights”) set forth in the Certificate of Incorporation in connection with the Business Combination with respect to the Recycled Shares only during the term of this Confirmation. Subject to any restrictions set forth in this Confirmation, Seller may sell or otherwise transfer, loan or dispose of any of the Shares or any other shares or securities of the Counterparty in one or more public or private transactions at any time.

Unless specified in an OET Notice, no sale of Shares by Seller shall terminate all or any portion of this Confirmation and provided that Seller complies with all of its other obligations hereunder nothing contained herein shall limit any of Seller’s purchases and sales of Shares.

Counterparty represents and warrants to Seller that Counterparty is not entering into the Transaction to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) for the purpose of inducing the purchase or sale of such securities or otherwise in violation of the Exchange Act, and Counterparty represents and warrants to Seller that Counterparty has not entered into or altered, and agrees that Counterparty will not enter into or alter, any corresponding or hedging transaction or position with respect to the Shares.

Counterparty acknowledges and agrees that any amendment, modification, waiver or termination of this Confirmation must be effected in accordance with the requirements for the amendment or termination of a written trading plan for trading securities. Without limiting the generality of the foregoing, Counterparty acknowledges and agrees that any such amendment, modification, waiver or termination shall be made in good faith and not as part of a plan or scheme to evade compliance with the federal securities laws, including without limitation the prohibition on manipulative and deceptive devises under the Exchange Act and no such amendment, modification or waiver shall be made at any time at which Counterparty or any officer, director, manager or similar person of Counterparty is aware of any material non-public information regarding Counterparty or the Shares.

Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares (other than in connection with a Counterparty equity compensation program (e.g., to fund taxes in connection with vested RSUs)), promptly give Seller a written notice of such repurchase (a “Repurchase Notice”), if following such repurchase, the number of outstanding Shares as determined on such day is (i) less than the number of Shares outstanding that would result in the percentage of total Shares outstanding represented by the number of Shares underlying the Transaction increasing by 0.10% (in the case of the first such notice) or (ii) thereafter more than the number of Shares that would need to be repurchased to result in the percentage of total Shares outstanding represented by the number of Shares underlying the Transaction increasing by a further 0.10% less than the number of Shares included in the immediately preceding Repurchase Notice; provided that Counterparty agrees that this information does not constitute material non-public information; provided further if this information shall be material non-public information, it shall publicly disclosed immediately. Counterparty agrees to indemnify and hold harmless Seller and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses (including losses relating to Seller’s hedging activities as a consequence of remaining or becoming a Section 16 “insider” following the closing of the Business Combination, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and reasonable and documented out-of-pocket expenses (including reasonable and documented attorney’s fees), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Seller with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within thirty days, upon written request, each of such Indemnified Persons for any reasonable and documented legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing; provided, however, for the avoidance of doubt, Counterparty has no indemnification or other obligations with respect to Seller becoming a Section 16 “insider” prior to the closing of the Business Combination. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Seller with a Repurchase Notice in accordance with this paragraph, such Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall

Transfer or Assignment. The rights and duties under this Confirmation may not be transferred or assigned by any party hereto without the prior written consent of the other party, such consent not to be unreasonably withheld, subject to the immediately following sentence. If at any time following the closing of the Business Combination at which (A) the Section 16 Percentage exceeds 9.9%, or (B) the Share Amount exceeds the Applicable Share Limit, if any applies (any such condition described in clause (A) or (B), an “Excess Ownership Position”), Seller is unable to effect a transfer or assignment of a portion of the Transaction to a third party on pricing terms reasonably acceptable to Seller and within a time period reasonably acceptable to Seller such that no Excess Ownership Position exists, then Seller may designate any Local Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”), such that following such partial termination no Excess Ownership Position exists. In the event that Seller so designates an Early Termination Date with respect to a portion of the Transaction, a portion of the Shares with respect to the Transaction shall be delivered to Counterparty as if the Early Termination Date was the Valuation Date in respect of a Transaction having terms identical to the Transaction and a Number of Shares equal to the number of Shares underlying the Terminated Portion. The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, as determined by Seller, (A) the numerator of which is the number of Shares that Seller and each person subject to aggregation of Shares with Seller under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder and all persons who may form a “group” (within the meaning of Rule 13d-5(b)(1) of the Exchange Act) with Seller directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) (the “Seller Group” ) and (B) the denominator of which is the number of Shares outstanding.

Indemnification. Counterparty agrees to indemnify and hold harmless each Indemnified Person from and against any and all losses (but not including financial losses to an Indemnified Person relating to the economic terms of the Transaction provided that the Counterparty performs its obligations under this Confirmation in accordance with its terms), claims, damages and liabilities (or actions in respect thereof) expenses (including reasonable attorney’s fees), joint or several, incurred by or asserted against such Indemnified Person arising out of, in connection with, or relating to, and to reimburse, within thirty days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, whether arising out of any action between any of the Indemnified Parties and the Counterparty or between any of the Indemnified Parties and any third party, or otherwise) to which they or any of them may become subject under the Securities Act, the Exchange Act or any other statute or at common law or otherwise or under the laws of foreign countries, arising out of or based upon the Transaction, including the execution or delivery of this Confirmation, the performance by Counterparty of its obligations under the Transaction, any material breach of any covenant, representation or warranty made by Counterparty or Target in this Confirmation or the ISDA Form, regulatory filings and submissions made by or on behalf of the Counterparty related to the Transaction (other than as relates

In the event that another investor is afforded any such more favorable terms than Seller, the Counterparty shall promptly inform Seller of such more favorable terms in writing, and Seller shall have the right to elect to amend this Confirmation and to the extent required to ensure that the terms of this Confirmation are as favorable to Seller as the terms of such other agreements are to such other investors, in which case the parties hereto shall promptly amend this Confirmation to effect the same.
