The term “Counterparty” refers to GFOR until the Business Combination (as defined below), then following the Business Combination, to NKGen Biotech, Inc., a Delaware corporation (“PubCo”), which such name change will happen at or immediately prior to the closing of the Business Combination, concurrently with Target being renamed as “NKGen Operating Biotech, Inc.” In connection with the transactions contemplated by the BCA (as defined below), (i) Austria Merger Sub, Inc., a Delaware corporation and a direct wholly-owned subsidiary of PubCo (“Merger Sub”) will merge with and into Target, with Target as the surviving entity and a wholly-owned subsidiary of PubCo (the “Merger”, and together with the other transactions contemplated by the BCA, the “Business Combination”). Certain terms of the Transaction shall be as set forth in this Confirmation, with additional terms as set forth in a pricing date notice (the “Pricing Date Notice”) in the form of Schedule A hereto. This Confirmation, together with the Pricing Date Notice(s), constitutes a “Confirmation” and the Transaction constitutes a separate “Transaction” as referred to in the ISDA Form (as defined below).

This Confirmation, together with the Pricing Date Notice, shall supplement, form a part of, and be subject to an agreement in the form of the ISDA 2002 Master Agreement (the “ISDA Form”) as if Seller, Target and Counterparty had executed an agreement in such form (but without any Schedule except as set forth herein under “Schedule Provisions”) on the Trade Date of the Transaction.

Settlement Amount:		With respect to Recycled Shares or Additional Shares that have been sold by Seller as of the Valuation Date and that are not Terminated Shares, a cash amount equal to the product of (x) the number of such Shares and (y) the Reset Price in respect of such Valuation Date. With respect to Recycled Shares or Additional Shares that have not been sold by Seller as of the Valuation Date, a cash amount equal to (x) the number of such Shares as of the Valuation Date less the number of Unregistered Shares (as defined below), multiplied by (y) the volume weighted daily VWAP Price over the Valuation Period; provided that the Settlement Amount shall not be less than zero. In the event that Seller has delivered a Registration Request at least 90 days prior to the Valuation Date, Shares which are set forth in Pricing Date Notices that are neither registered for resale under an effective resale Registration Statement nor transferable without any restrictions pursuant to an exemption from the registration requirements of Section 5 of the Securities Act, including pursuant to Rule 144 (so long as not subject to the requirement for the Counterparty to be in compliance with the current public information required under Rule 144I(1) (or Rule 144(i)(2), if applicable) the volume and manner of sale limitations under Rule 144(e), (f) and (g)) (in either event, “Unregistered Shares”) will not be included in the calculation of the Settlement Amount with respect to Recycled Shares or Additional Shares that have not been sold by Seller prior to the Valuation Date.
Settlement Amount Adjustment:		A cash amount equal to the product of (1) the number of Recycled Shares and Additional Shares that have not been sold by Seller as of the Valuation Date multiplied by (2) $2.00. The Settlement Amount Adjustment shall be paid (x) in the event that the expected Settlement Amount determined by the VWAP Price over the 15 scheduled trading days ending on but excluding the Valuation Date exceeds the Settlement Amount Adjustment, in cash (in which case the Settlement Amount Adjustment will be automatically netted from the Settlement Amount and any remaining amount paid in cash), or (y) otherwise, at the option of Counterparty, in cash or Shares (such Shares, the “Maturity Shares”) (other than in the case of a Delisting Event, in which case the Settlement Amount Adjustment must be paid in cash).  In the event that Counterparty is eligible to pay the Settlement Amount Adjustment using Maturity Shares, Counterparty will be deemed to have elected to pay the Settlement Amount Adjustment in Maturity Shares unless Counterparty notifies Seller no later than ten Local Business Days prior to the Valuation Date that Counterparty elects to pay the Settlement Amount Adjustment in cash.  In the event the Settlement Amount Adjustment is paid in Maturity Shares then, on the Valuation Date, Counterparty shall deliver to Seller an initial calculation of the Maturity Shares equal to (a) the Settlement Amount Adjustment divided by (b) the volume weighted daily VWAP Price over the 15 scheduled trading days ending on but excluding the Valuation Date (the “Estimated Maturity Shares”).  The total number of Maturity Shares to be delivered to Seller by Counterparty shall be based on the volume weighted daily VWAP Price over the Valuation Period (the “Final Maturity Shares”).  On the Local Business Day following the end of the Valuation Period, (i) if the Final Maturity Shares exceeds the Estimated Maturity Shares, Counterparty shall deliver to Seller an additional number of Maturity Shares equal to such excess, and (ii) if the volume weighted daily VWAP Price over the Valuation Period multiplied by the Estimated Maturity Shares exceeds the Settlement Amount Adjustment, Seller shall deliver to Counterparty a cash amount equal to such excess.  By no later than the start of the Valuation Period, all Maturity Shares shall be registered for resale by the Counterparty under an effective resale Registration Statement pursuant to the Securities Act under which Seller may sell or transfer the Shares and, subject to the receipt of Seller representation letters and such other customary supporting documentation as requested by (and in a form reasonably acceptable to) Counterparty and its counsel, bear no restrictive legend; provided, however, that Counterparty shall not be able to pay the Settlement Amount Adjustment with Maturity Shares if following the issuance of the Maturity Shares, Seller’s ownership of Shares would exceed 9.9% ownership of the total Shares outstanding immediately after giving effect to such issuance unless Seller at its sole discretion waives such 9.9% ownership limitation.  To the extent that a Delisting Event occurs during the Valuation Period, the VWAP Price for the remainder of the Valuation Period shall be deemed to be zero and any election to pay the Settlement Amount Adjustment with Maturity Shares will automatically revert to a requirement that the Settlement Amount Adjustment be paid in cash such that any further payment that is to be made of the Settlement Amount Adjustment as provided above shall be made by Seller in cash.

6

Valuation Period:		The period commencing on the Valuation Date (or if the Valuation Date is not an Exchange Business Day, the first Exchange Business Day thereafter) and ending at 4:00 pm on the Exchange Business Day on which 10% of the total volume traded in the Shares over the period, excluding any volumes traded during the opening and closing auctions, has reached an amount equal to the Number of Shares outstanding as of the Valuation Date plus the Estimated Maturity Shares, less the number of Shares owned by Seller that are neither registered for resale under an effective resale Registration Statement nor eligible for resale under Rule 144 without volume or manner of sale limitations (but only counting such Shares that are eligible for resale under Rule 144 to the extent the Counterparty is in compliance with the requirements of Rule 144(i)(2) for the entire period).
Settlement Currency:		USD.
Cash Settlement Payment Date:		The tenth Local Business Day immediately following the last day of the Valuation Period.
Excess Dividend Amount:		Ex Amount.
Optional Early Termination:		From time to time and on any date following the Trade Date (any such date, an “OET Date”) and subject to the terms and conditions below, Seller may, in its absolute discretion, terminate the Transaction in whole or in part by providing written notice to Counterparty, and if applicable, the Escrow Agent (the “OET Notice”), no later than the next Payment Date following the OET Date, (which shall specify the quantity by which the Number of Shares shall be reduced (such quantity, the “Terminated Shares”)); provided that “Terminated Shares” includes only such quantity of Shares by which the Number of Shares is to be reduced and included in an OET Notice and does not include any other Share sales, Shortfall Sale Shares or sales of Shares that are designated as Shortfall Sales (which designation can be made only up to the amount of Shortfall Sale Proceeds), any Share Consideration Shares sales or any other Shares, whether or not sold, which Shares will not be included in any OET Notice or included in the definition, or when calculating the number, of Terminated Shares.  The effect of an OET Notice shall be to reduce the Number of Shares by the number of Terminated Shares specified in such OET Notice with effect as of the related OET Date.  As of each OET Date, Counterparty shall be entitled to an amount from Escrow Account and the Escrow Agent shall pay to Counterparty an amount, equal to the product of (x) the number of Terminated Shares and (y) the Reset Price in respect of such OET Date (an “Early Termination Obligation”), except that no such amount will be due to Counterparty upon any Shortfall Sale; provided, that, the Escrow Agent shall pay the Early Termination Obligation to the accounts and in the amounts as directed by Counterparty.  The remainder of the Transaction, if any, shall continue in accordance with its terms.  The Early Termination Obligation shall be payable by the Escrow Agent on the first Local Business Day following the date of delivery by the Escrow Agent of the OET Notice.  For the avoidance of doubt, no other amounts as may be set forth in Sections 16.1 and 18.1 of the Swap Definitions shall be due to Counterparty upon an Optional Early Termination.  The payment date may be changed within a quarter at the mutual agreement of the parties.

Shortfall Sales:		From time to time and on any date following the Trade Date (any such date, a “Shortfall Sale Date”) and subject to the terms and conditions below, Seller may, in its absolute discretion, sell Shortfall Sale Shares, with sales during the first six months following the Trade Date being sold at a price no less than the Reset Price, and in connection with such sales, Seller shall provide written notice to Counterparty (the “Shortfall Sale Notice”) no later than the later of (a) the fifth Local Business Day following the Shortfall Sales Date and (b) the first Payment Date after the Shortfall Sales Date, specifying the quantity of the Shortfall Sale Shares and the allocation of the Shortfall Sale Proceeds. Seller shall not have any Early Termination Obligation in connection with any Shortfall Sales. The Counterparty covenants and agrees for a period of at least sixty Local Business Days (commencing on the Prepayment Date or if an earlier Registration Request is submitted by Seller on the Registration Statement Effective Date) not to issue, sell or offer or agree to sell more than $20 million of Shares, or securities or debt that is convertible, exercisable or exchangeable into Shares, including under any existing or future equity line of credit, until the Shortfall Sales equal the Prepayment Shortfall, without the Seller’s consent; provided, however, that nothing in the foregoing covenant shall prohibit (i) the grant, issuance or exercise of employee stock options or other equity awards under the Counterparty’s equity compensation plans, (ii) the issuance of any securities issued or assumed in connection with the Business Combination, or (iii) repricing of Counterparty’s warrants in connection with the closing of the Business Combination.
		Unless and until the proceeds from Shortfall Sales equal 100% of the Prepayment Shortfall, in the event that the product of (x) the difference between (i) the number of Shares as specified in the Pricing Date Notice(s), less (ii) any Shortfall Sale Shares as of such measurement time, multiplied by (y) the VWAP Price, is less than (z) the difference between (i) the Prepayment Shortfall, less (ii) the proceeds from Shortfall Sales as of such measurement time (the “Shortfall Variance”), then the Counterparty, as liquidated damages in respect of such Shortfall Variance, at its option shall within five (5) Local Business Days either:
		(A) Pay in cash an amount equal to the Shortfall Variance; or
		(B) Issue and deliver to Seller such number of additional Shares that are equal to (1) the Shortfall Variance, divided by (2) 90% of the VWAP Price (the “Shortfall Variance Shares”).

In the event that the Counterparty issues and delivers to Seller Shortfall Variance Shares, within thirty calendar days of such issuance and delivery, Counterparty shall use its commercially reasonable efforts to file (at Counterparty’s sole cost and expense) with the U.S. Securities and Exchange Commission (the “Commission”) a registration statement registering the resale of all shares held by the Seller, including the Recycled Shares (the “Shortfall Variance Registration Statement”), provided, that, the Counterparty’s obligations to file such Shortfall Variance Registration Statement shall be contingent upon Seller furnishing in writing to the Counterparty a completed selling stockholder questionnaire in customary form that contains such information regarding Seller, the securities of the Counterparty held by Seller and the intended method of disposition of the shares as shall be reasonably requested by the Counterparty to effect the registration of the shares, and shall use its commercially reasonable efforts to have the Shortfall Variance Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earliest of (i) the 90th calendar day (or 120th calendar day if the Commission notifies the Counterparty that it will “review” the Shortfall Variance Registration Statement) following the issuance and delivery of the Shortfall Variance Shares and (ii) the 10th Local Business Day after the date the Counterparty is notified (orally or in writing, whichever is earlier) by the Commission that such Shortfall Variance Registration Statement will not be “reviewed” or will not be subject to further review. Upon notification by the Commission that the Shortfall Variance Registration Statement has been declared effective by the Commission, within two Local Business Days thereafter, the Counterparty shall file the final prospectus under Rule 424 of the Securities Act of 1933, as amended containing a “plan of distribution” reasonably agreeable to Seller. Counterparty shall not identify Seller as a statutory underwriter in the Registration Statement unless requested by the Commission. In the event that the SEC asks that Seller be identified as a statutory underwriter, Seller shall have the option, in its sole discretion and without any breach of this provision or without any Registration Failure deemed to have occur, to remove its shares from the Shortfall Variance Registration Statement. The Counterparty will use its commercially reasonable efforts to keep the Shortfall Variance Registration Statement covering the resale of the shares as described above continuously effective (except that the Counterparty shall be entitled to postpone and suspend the effectiveness or use of the Shortfall Variance Registration Statement (i) during any customary blackout or similar period or as permitted hereunder and (ii) as may be necessary in connection with the preparation and filing of a post-effective amendment to the Registration Statement following the filing of the Counterparty’s Annual Report on Form 10-K), until all such Shortfall Variance Shares have been sold or may be transferred without any restrictions, including the requirement for the Counterparty to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable) or the volume and manner of sale limitations under Rule 144(e), (f) and (g) under the Securities Act. Seller shall not be entitled to use the Shortfall Variance Registration Statement for an underwritten offering of Shortfall Variance Shares. Notwithstanding anything to the contrary contained herein, the Counterparty may delay or postpone filing of such Shortfall Variance Registration Statement, and from time to time require Seller not to sell under the Shortfall Variance Registration Statement or suspend the use or effectiveness of any such Shortfall Variance Registration Statement if it determines in good faith that in order for the registration statement to not contain a material misstatement or omission, an amendment thereto would be needed, or if such filing or use would reasonably be expected to materially affect a bona fide business or financing transaction of the Counterparty or would reasonably be expected to require premature disclosure of information that would materially adversely affect the Counterparty (each such circumstance, a “Suspension Event”); provided, that, (w) the Counterparty shall not so delay filing or so suspend the use of the Shortfall Variance Registration Statement for a period of more than sixty (60) consecutive days or more than two (2) times in any three hundred sixty (360) day period, and (x) the Counterparty shall use commercially reasonable efforts to make such registration statement available for the sale by Seller of such Shortfall Variance Shares as soon as practicable thereafter. If requested by Seller, the Counterparty shall within five (5) Local Business Days of receipt of such request, subject to receipt of a legal opinion of Counterparty’s counsel, instruct its transfer agent to remove any restrictive legend with respect to transfers under the Securities Act from Shortfall Variance Shares that have been sold pursuant to an effective registration statement or Rule 144 under the Securities Act (subject to all applicable requirements of Rule 144 being met); provided that Seller and its broker shall have timely provided customary representations and other documentation reasonably acceptable to the Counterparty, its counsel and/or its transfer agent in connection therewith. Any fees (with respect to the transfer agent, Counterparty’s counsel or otherwise) associated with the issuance of any legal opinion required by the Counterparty’s transfer agent or the removal of such legend shall be borne by the Counterparty.

Any Shortfall Variance Shares shall constitute Shortfall Shares, and the sale of such Shortfall Variance Shares after the Shortfall Variance Registration Statement is declared effective by the Commission shall be a Shortfall Sale. If the Shortfall Variance has not been paid in cash by the Counterparty, and after the sale of all Shortfall Variance Shares, the proceeds from all Shortfall Sales, including the Shortfall Variance Shares, is less than 100% of the Prepayment Shortfall, then there will be another Shortfall Variance, calculated in accordance with this provision, and the Counterparty shall address such Shortfall Variance as provided for by this provision. This shall continue until such time as the proceeds from all Shortfall Sales equal 100% of the Prepayment Shortfall or the Counterparty shall have paid any Shortfall Variance in cash.

With respect to the forgoing and any issuance of Shortfall Variance Shares, the Counterparty shall not issue any Shortfall Variance Shares pursuant to this provision to the extent that after giving effect thereto, the aggregate number of Shares that would be issued pursuant to this provision would exceed 19.99% of the Shares that are issued and outstanding immediately prior to such issuance, which number of shares shall be (i) reduced, on a share-for-share basis, by the number of Shares issued or issuable pursuant to any transaction or series of transactions that may be aggregated with the transactions contemplated hereby under applicable rules of the Nasdaq and (ii) appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split or other similar transaction that occurs after the date of this Confirmation (such maximum number of shares, the “Exchange Cap”), unless and until the Counterparty elects to solicit stockholder approval of the issuance of the Shortfall Variance Shares as contemplated hereby, and the stockholders of the Counterparty have in fact approved the issuance of the Shortfall Variance Shares as contemplated hereby in accordance with the applicable rules of the Nasdaq. In the event that there is an Exchange Cap, if the Counterparty does not elect to solicit stockholder approval and obtain such stockholder approval in accordance with the applicable rules of the Nasdaq, then the Counterparty will pay the Shortfall Variance in cash.

Share Registration:		Within 30 days after receipt of a written request of Seller (the “Registration Request”), which request may be made no earlier than the Trade Date (as defined above) and no later than the Valuation Date, Counterparty use commercially reasonable efforts to file (at Counterparty’s sole cost and expense) with the U.S. Securities and Exchange Commission (the “Commission”) a registration statement registering the resale of all shares held by the Seller, including the Recycled Shares and Share Consideration Shares (but excluding any Additional Shares, with registration rights for such Additional Shares governed by the PIPE Subscription Agreement) (the “Registration Statement”), provided, that, the Counterparty’s obligations to file the Registration Statement shall be contingent upon Seller furnishing in writing to the Counterparty a completed selling stockholder questionnaire in customary form that contains such information regarding Seller, the securities of the Counterparty held by Seller and the intended method of disposition of the shares as shall be reasonably requested by the Counterparty to effect the registration of the shares, and shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earliest of (i) the 90th calendar day (or 120th calendar day if the Commission notifies the Counterparty that it will “review” the Registration Statement) following the date of the Registration Request (provided, however, that in the event the Commission issues any written rules related to special purpose acquisition companies that would reasonably effect the timing of the effectiveness of the Registration Statement and such rules become effective following the date hereof and prior to the effectiveness of the Registration Statement, such number of calendar days in this subsection (i) shall be changed to the 120th calendar day (or 180th calendar day if the Commission notifies the Counterparty that it will “review” the Registration Statement) and (ii) the 10th Local Business Day after the date the Counterparty is notified (orally or in writing, whichever is earlier) by the Commission that such Registration Statement will not be “reviewed” or will not be subject to further review (each respective date as described above, the “Effectiveness Deadline”); provided, that (x) if such day falls on a Saturday, Sunday or other day that the Commission is closed for business, the Effectiveness Deadline shall be extended to the next Local Business Day on which the Commission is open for business and (y) if the Commission is closed for operations due to a government shutdown, the Effectiveness Deadline shall be extended by the same number of Local Business Days that the Commission remains closed for. Upon notification by the Commission that the Registration Statement has been declared effective by the Commission, within two Local Business Days thereafter, the Counterparty shall file the final prospectus under Rule 424 of the Securities Act of 1933, as amended, containing a “plan of distribution” reasonably agreeable to Seller.

Counterparty shall not identify Seller as a statutory underwriter in the Registration Statement unless requested by the Commission. In the event that the SEC asks that Seller be identified as a statutory underwriter, Seller shall have the option, in its sole discretion and without any breach of this provision or without any Registration Failure deemed to have occur, to remove its shares from the Registration Statement. The Counterparty will use its commercially reasonable efforts to keep the Registration Statement covering the resale of the shares as described above continuously effective (except that the Counterparty shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement (i) during any customary blackout or similar period or as permitted hereunder (a “Blackout Period Suspension”) and (ii) as may be necessary in connection with the preparation and filing of a post-effective amendment to the Registration Statement following the filing of the Counterparty’s Annual Report on Form 10-K (the “10-K Post-Effective Amendment Suspension”)), until all such shares have been sold or may be transferred without any restrictions, including the requirement for the Counterparty to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable) or the volume and manner of sale limitations under Rule 144(e), (f) and (g) under the Securities Act. Seller shall not be entitled to use the Registration Statement for an underwritten offering of Shares. Notwithstanding anything to the contrary contained herein, the Counterparty may delay or postpone filing of such Registration Statement, and from time to time require Seller not to sell under the Registration Statement or suspend the use or effectiveness of any such Registration Statement if there is a Suspension Event; provided, that, (w) the Counterparty shall not so delay filing or so suspend the use of the Registration Statement for a period of more than sixty (60) consecutive days or more than two (2) times in any three hundred sixty (360) day period, and (x) the Counterparty shall use commercially reasonable efforts to make such registration statement available for the sale by Seller of such Shares as soon as practicable thereafter, provided that Counterparty covenants and agrees to make all necessary filings, amendments, supplements and submissions in furtherance of the foregoing, including to register all of Seller’s Shares for resale; provided further, that it shall be a “Registration Failure” if (a) the Registration Statement covering all of the shares described above in this section is not declared effective after the 90th calendar day (or 120th calendar day if the Commission notifies the Counterparty that it will “review” the Registration Statement) after the Trade Date (provided, however, that in the event the Commission issues any written rules related to special purpose acquisition companies that would reasonably effect the timing of the effectiveness of the Registration Statement and such rules become effective following the date hereof and prior to the effectiveness of the Registration Statement, such number of calendar days in this subsection (i) shall be changed to the 120th calendar day (or 180th calendar day if the Commission notifies the Counterparty that it will “review” the Registration Statement) and or (b) the Registration Statement after it is declared effective ceases to be continuously effective (subject to the Blackout Period Suspensions and 10-K Post-Effective Amendment Suspension as indicated above and any Suspension Event) as set forth in the preceding sentence for more than 120 consecutive calendar days; provided, that (x) if such day falls on a Saturday, Sunday or other day that the Commission is closed for business, the Effectiveness Deadline shall be extended to the next Local Business Day on which the Commission is open for business and (y) if the Commission is closed for operations due to a government shutdown, the Effectiveness Deadline shall be extended by the same number of Local Business Days that the Commission remains closed for. Notwithstanding the foregoing, no Registration Failure will be deemed to have occurred with respect to any Shares that may be transferred at such time under Rule 144 (without volume or manner of sale limitations), so long as the Counterparty is in compliance with the requirements of Rule 144 (c)(1) and (i)(2), if applicable.

9

Seller will promptly deliver customary representations and other documentation reasonably acceptable to the Counterparty, its counsel and/or its transfer agent in connection with the Registration Statement, including those related to selling stockholders, and to respond to SEC comments. If requested by Seller, the Counterparty shall remove or instruct its transfer agent to remove any restrictive legend with respect to transfers under the Securities Act from Shares that have been sold pursuant to (i) an effective and available registration statement and current prospectus or (ii) Rule 144 under the Securities Act (subject to all applicable requirements of Rule 144 being met); provided that Seller and its broker shall have timely provided customary representations and other documentation reasonably acceptable to the Counterparty, its counsel and/or its transfer agent in connection therewith. Any reasonable and documented fees (with respect to the transfer agent, Counterparty’s counsel or otherwise) associated with the removal of such legend shall be borne by the Counterparty. If a legend is removed pursuant to the foregoing sentence, the Counterparty will, no later than five Local Business Days following the delivery by Seller to the Counterparty or the transfer agent (with notice to the Counterparty) of customary representations and other documentation reasonably acceptable to the Counterparty, its counsel and/or its transfer agent, remove the restrictive legend related to such Shares that have been sold.

Notwithstanding the registration obligations set forth in this Share Registration section, in the event the Commission informs the Counterparty that all of the Shares cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Counterparty agrees to promptly (i) inform Seller and use its commercially reasonable efforts to file amendments to the Registration Statement as required by the Commission and/or (ii) withdraw the Registration Statement and file a new registration statement (a “New Registration Statement”), on Form S-3, or if Form S-3 is not then available to the Counterparty for such registration statement, on such other form available to register for resale the Shares as a secondary offering; provided, however, that prior to filing such amendment or New Registration Statement, the Counterparty shall use its commercially reasonable efforts to advocate with the Commission for the registration of all of the Shares in accordance with any publicly-available written or oral guidance, comments, requirements or requests of the Commission staff (the “SEC Guidance”). Notwithstanding any other provision of this Agreement, if any SEC Guidance sets forth a limitation of the number of securities permitted to be registered on a particular Registration Statement as a secondary offering (and notwithstanding that the Counterparty used commercially reasonable efforts to advocate with the Commission for the registration of all or a greater number of the Shares), unless otherwise directed in writing by a selling stockholder as to its securities to register fewer securities, the number of securities to be registered on such Registration Statement will be reduced on a pro rata basis among all selling stockholders named in such Registration Statement (except that such pro rata reduction shall not apply with respect to any securities the registration of which is necessary to satisfy applicable listing rules of a national securities exchange). In the event the Counterparty amends the Registration Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, the Counterparty will use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Counterparty or to registrants of securities in general, one or more registration statements on Form S-3 or such other form available to register for resale that portion of Shares that were not registered for resale on the Registration Statement, as amended, or the New Registration Statement, and to use commercially reasonable efforts to seek effectiveness of the New Registration Statement, but in any event no later than thirty (30) calendar days after the filing of such Registration Statement (the “Additional Effectiveness Deadline”); provided, that the Additional Effectiveness Deadline shall be extended to ninety (90) calendar days (or one hundred twenty (120) calendar days if the Commission notifies the Counterparty that it will “review” the New Registration Statement) if such New Registration Statement is reviewed by, and comments thereto are provided from, the Commission; provided, further, that the Counterparty shall have such Registration Statement declared effective within five (5) Local Business Days after the date the Counterparty is notified (orally or in writing, whichever is earlier) by the staff of the Commission that such New Registration Statement will not be “reviewed” or will not be subject to further review; provided, further, that (x) if such day falls on a Saturday, Sunday or other day that the Commission is closed for business, the Additional Effectiveness Deadline shall be extended to the next Local Business Day on which the Commission is open for business and (y) if the Commission is closed for operations due to a government shutdown, the Additional Effectiveness Deadline shall be extended by the same number of Local Business Days that the Commission remains closed for. For the avoidance of doubt, any such amendments to or withdrawal of the Registration Statement or filing of the New Registration Statement shall not constitute a Registration Failure.

Other Provisions.

(a) Rule 10b-5.

(i) 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, in each case, except for other forward purchase agreements.

(ii) Counterparty acknowledges and agrees that Counterparty does not have, and shall not attempt to exercise, any influence over how, when or whether Seller effects any purchases of Shares in connection with the Transaction. Counterparty represents and warrants that it has consulted with its own advisors as to the legal aspects of its adoption and implementation of this Confirmation and the Transaction under the federal securities laws, including without limitation, the prohibitions on manipulative and deceptive devices under the Exchange Act.

(iii) 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.

(b) 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 contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the Transaction.

20

(c) 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.   The “Share Amount” as of any day is the number of Shares that Seller and any person whose ownership position would be aggregated with that of Seller and any group (however designated) of which Seller is a member (Seller or any such person or group, a “Seller Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Seller in its sole discretion.   The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting (other than on Schedule 13D or 13G) or registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Seller Person, or could result in an adverse effect on a Seller Person, under any Applicable Restriction, as determined by Seller in its sole discretion, minus (B) 0.1% of the number of Shares outstanding.

(d) 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 to any information provided in writing by or on behalf of Seller or its affiliates), or the consummation of the transactions contemplated hereby, including the Registration Statement or any untrue statement or alleged untrue statement of a material fact contained in any registration statement, press release, filings or other document, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. Counterparty will not be liable under the foregoing indemnification provision to the extent that any loss, claim, damage, liability or expense is related to the manner in which Seller sells, or arising out of any sales by Seller of, any Shares, including the Recycled Shares and the Additional Shares or found in a nonappealable judgment by a court of competent jurisdiction to have resulted from Seller’s material breach of any covenant, representation or other obligation in this Confirmation or the ISDA Form or from Seller’s willful misconduct, bad faith or gross negligence in performing the services that are subject of the Transaction. If for any reason the foregoing indemnification is unavailable to any Indemnified Person or insufficient to hold harmless any Indemnified Person, then Counterparty shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Person as a result of such loss, claim, damage or liability. In addition (and in addition to any other Reimbursement of Legal Fees and other Expenses contemplated by this Confirmation), Counterparty will reimburse any Indemnified Person for all reasonable, out-of-pocket, expenses (including reasonable counsel fees and expenses) as they are incurred in connection with the investigation of, preparation for or defense or settlement of any pending or threatened claim or any action, suit or proceeding arising therefrom, whether or not such Indemnified Person is a party thereto and whether or not such claim, action, suit or proceeding is initiated or brought by or on behalf of Counterparty. Counterparty also agrees that no Indemnified Person shall have any liability to Counterparty or any person asserting claims on behalf of or in right of Counterparty in connection with or as a result of any matter referred to in this Confirmation except to the extent that any losses, claims, damages, liabilities or expenses incurred by Counterparty result from such Indemnified Person’s breach of any covenant, representation or other obligation in this Confirmation or the ISDA Form or from the gross negligence, willful misconduct or bad faith of the Indemnified Person or breach of any U.S. federal or state securities laws or the rules, regulations or applicable interpretations of the Commission. The provisions of this paragraph shall survive the completion of the Transaction contemplated by this Confirmation and any assignment and/or delegation of the Transaction made pursuant to the ISDA Form or this Confirmation shall inure to the benefit of any permitted assignee of Seller.

21

(f) Waiver of Jury Trial.

(g) Attorney and Other Fees.
