The Exchange Agent shall, following the Effective Time, pursuant to irrevocable instructions from Parent, deliver the Merger Consideration to be issued pursuant to this Article III out of the Exchange Fund. The cash portion, if any, of the Exchange Fund shall be invested by the Exchange Agent as directed by Parent; provided, that (i) no such investment of or losses thereon shall relieve Parent from making or causing to be made the

-31-

payments required by this Section 3.2 or elsewhere in this Article III, or affect the amount payable in respect of the shares of SpinCo Common Stock and/or SpinCo Equity Awards outstanding as of immediately prior to the Effective Time, (ii) to the extent the Exchange Fund is insufficient at any time to make such payments, Parent shall promptly provide additional funds to the Exchange Agent in the amount of any such deficiency and (iii) no such investment shall have maturities that would reasonably be expected to prevent or delay the payments to be made pursuant to this Section 3.2. Any interest or other income from such investments shall be paid to and become the property of Parent. The Exchange Fund shall not be used for any purpose other than as specified in this Section 3.2(b). No later than five (5) Business Days prior to the Effective Time, Parent shall enter into an agreement with the Exchange Agent, in form and substance reasonably satisfactory to the Company, to effect the applicable terms of this Agreement (the “Exchange Agent Agreement”).

(c) As promptly as practicable after the Effective Time, Parent shall cause the Exchange Agent to deliver to each holder of shares of SpinCo Common Stock and/or SpinCo Equity Awards as of immediately prior to the Effective Time, from the Exchange Fund, the shares of Domesticated Parent Stock issuable in respect of such shares of SpinCo Common Stock and/or SpinCo Equity Awards pursuant to the Merger, which shares shall, for the sake of clarity, be delivered to the same Persons who received shares of SpinCo Common Stock and/or SpinCo Equity Awards in the Distribution. Each holder of shares of SpinCo Common Stock and/or SpinCo Equity Awards as of immediately prior to the Effective Time shall be entitled to receive in respect of such shares of SpinCo Common Stock and/or SpinCo Equity Awards held by such Person (i) a book-entry authorization representing the number of whole shares of Domesticated Parent Common Stock that such holder has the right to receive pursuant to Section 3.1(a)(i)(A) (and cash in lieu of fractional shares of Domesticated Parent Common Stock, as contemplated by Section 3.2(e), and any dividends or distributions and other amounts pursuant to Section 3.2(d)) and/or (ii) a book-entry authorization representing the number of Earnout Shares that such holder has the right to receive pursuant to Section 3.1(a)(i)(B), Section 3.3 and Section 3.5, in each case, without duplication. The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to Domesticated Parent Stock held by it from time to time hereunder or under the Exchange Agent Agreement.

(d) Distributions After the Effective Time. Subject to the following sentence, no dividends or other distributions declared after the Effective Time with respect to Domesticated Parent Common Stock shall be paid with respect to any shares of Domesticated Parent Stock that are not able to be delivered by the Exchange Agent promptly after the Effective Time, whether due to a legal impediment to such delivery or otherwise. Subject to the effect of abandoned property, escheat, Tax or other applicable Laws, following the delivery of any such previously undelivered shares of Domesticated Parent Stock, there shall be paid to the record holder of such shares of Domesticated Parent Common Stock, without interest, at the time of delivery, to the extent not previously paid, (i) the amount of cash payable in lieu of a fractional share of Domesticated Parent Common Stock to which such holder is entitled pursuant to Section 3.2(e) and (ii) the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Domesticated Parent Stock.

-32-

(e) No Fractional Shares.

(i) No certificates or scrip representing fractional shares of Domesticated Parent Stock or book-entry credit of the same shall be issued on conversion of SpinCo Common Stock and/or SpinCo Equity Awards, and such fractional share interests will not entitle the owner thereof to vote, or to any other rights of a stockholder of Parent. All fractional shares of Domesticated Parent Common Stock that a holder of shares of SpinCo Common Stock would otherwise be entitled to receive as a result of the Merger shall be aggregated by the Exchange Agent. The Exchange Agent shall cause the whole shares obtained thereby to be sold on behalf of such holders that would otherwise have been entitled to receive a fractional share of Domesticated Parent Common Stock pursuant to the Merger in the open market (or otherwise as reasonably directed by Parent), in each case at then-prevailing market prices as soon as reasonably practicable and in no case later than ten (10) Business Days after the Effective Time. The Exchange Agent shall make available the net proceeds thereof, subject to the deduction of the amount of any withholding Taxes as contemplated in Section 3.2(j) and brokerage charges, commissions and conveyance and similar Taxes, to the holders of SpinCo Common Stock that would otherwise have been entitled to receive a fractional share of Domesticated Parent Common Stock pursuant to the Merger (after the aggregation contemplated by this Section 3.2(e)) on a pro rata basis based on such fractional interest, without interest, as soon as practicable thereafter. The payment of cash in lieu of fractional shares is solely for the purpose of avoiding the expense and inconvenience of issuing fractional shares and does not represent separately bargained-for consideration.

(ii) Notwithstanding anything to the contrary herein, no fraction of an Earnout Share will be issued by virtue of the Merger, and each holder of SpinCo Common Stock and/or SpinCo Equity Awards who would otherwise be entitled to a fraction of an Earnout Share (after aggregating all fractional Earnout Shares that otherwise would be received by such holder of SpinCo Common Stock and/or SpinCo Equity Awards) shall not receive from Parent any shares of Domesticated Parent Stock or other consideration in lieu of any such fractional share.

(f) No Further Ownership Rights in SpinCo Common Stock. All shares of Domesticated Parent Stock issued in respect of shares of SpinCo Common Stock and/or SpinCo Equity Awards in accordance with the terms of this Section 3.2 (including any cash paid pursuant to Section 3.2(d) or Section 3.2(e)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of SpinCo Common Stock and/or SpinCo Equity Awards.

(g) Termination of Exchange Fund. Any portion of the Exchange Fund made available to the Exchange Agent that remains undistributed to the former holders of SpinCo Common Stock and/or SpinCo Equity Awards on the one-year anniversary of the Effective Time shall be delivered to Parent, and any former holders of SpinCo Common Stock and/or SpinCo Equity Awards who have not received shares of Domesticated Parent Stock in accordance with this Article III shall thereafter look only to Parent for (i) in the case of former holders of SpinCo Common Stock, the Merger Consideration to which they are entitled pursuant to Section 3.1(a)(i), any cash in lieu of fractional shares of Domesticated Parent Common Stock to which they are entitled pursuant to Section 3.2(e) and any dividends or other distributions with respect to the Domesticated Parent Common Stock to which they are entitled pursuant to

-33-

Section 3.2(d) (subject to any applicable abandoned property, escheat or similar Law) and (ii) in the case of former holders of SpinCo Equity Awards, the Earnout Shares to which they are entitled pursuant to Section 3.3 and Section 3.5 and any dividends or other distributions with respect to the Earnout Shares to which they are entitled pursuant to Section 3.2(d) or Section 3.3(g).

To the extent that amounts are so deducted or withheld and paid over to the appropriate Governmental Authority, such deducted or withheld amounts will be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction or withholding was made.

Section 3.3 Earnout.

(a) Pursuant to the Merger, there shall be issued to each holder of a share of SpinCo Common Stock and each holder of a SpinCo Equity Award, their pro rata portion, as determined in accordance with the terms of Section 3.1(a) and the Employee Matters Agreement, as applicable, of an aggregate of 15,000,000 shares of Domesticated Parent Common Stock (without duplication), subject to the forfeiture provisions set forth in Section 3.3(d) (the “Earnout Shares”).

(b) The Earnout Shares shall be subject to the following vesting conditions:

(i) If, at any time during the period commencing on the Closing Date and ending on the date that is five years after the Closing Date (the “Earnout Period”), the Parent Trading Price is greater than or equal to $12.50, 50% of the Earnout Shares held by each holder of Earnout Shares shall immediately vest and no longer be subject to the forfeiture conditions provided in Section 3.3(d).

(ii) If, at any time during the Earnout Period, the Parent Trading Price is greater than or equal to $15.00, the remaining 50% of the Earnout Shares held by each holder of Earnout Shares shall immediately vest and no longer be subject to the forfeiture conditions provided in Section 3.3(d).

-34-

(c) For the avoidance of doubt, if the vesting conditions applicable to more than one of the provisions of Section 3.3(b) have been satisfied at any one time, then all of the Earnout Shares subject to such satisfied vesting conditions shall immediately vest and no longer be subject to the forfeiture conditions provided in Section 3.3(d).

(d) If, upon the expiration of the Earnout Period, the vesting of any of the Earnout Shares has not occurred, then the applicable Earnout Shares that failed to vest pursuant to Section 3.3(b), as applicable, shall be automatically forfeited and deemed transferred to Parent for cancellation for no consideration, and no Person (other than Parent) shall have any further right with respect thereto.

(e) If, during the Earnout Period, the Domesticated Parent Common Stock outstanding as of immediately following the Merger Effective Time shall have been changed into a different number of shares or a different class, by reason of any Equity Adjustment, or any similar event shall have occurred, then the applicable Parent Trading Price specified in Section 3.3(b) shall be equitably adjusted to reflect such change.

(f) If, during the applicable portion of the Earnout Period, there is a Change of Control that will result in the holders of Domesticated Parent Common Stock receiving a per share price equal to or in excess of the applicable Parent Trading Price required in connection with an applicable vesting event (an “Acceleration Event”), then immediately prior to the consummation of such Change of Control, any applicable Earnout Shares that have not previously been vested shall be deemed vested; provided, that such Earnout Shares shall be deemed vested (and such vesting event achieved) only (x) if such Change of Control has been approved by a majority of the independent directors on the Parent Board and (y) to the extent the price per share of Domesticated Parent Common Stock in the Change of Control equals or exceeds the applicable Parent Trading Price required in connection with such vesting event. For the avoidance of doubt, in the event of a Change of Control, including where the consideration payable is other than a specified price per share, for purposes of determining whether a Parent Trading Price required in connection with an applicable vesting event has been achieved, the price paid per share of Domesticated Parent Common Stock shall be calculated taking into account all of the Earnout Shares (whether or not then vested).

(g) For so long as any Earnout Shares remains subject to the vesting and forfeiture conditions specified in Section 3.3(b) and Section 3.3(d), the holder thereof shall be entitled to (i) exercise the voting rights carried by such Earnout Shares and (ii) receive any dividends or other distributions in respect of such Earnout Shares. For the avoidance of doubt, prior to vesting in accordance with the terms of this Section 3.3, holders of the Earnout Shares shall not be entitled to transfer such shares, and such shares shall bear a legend prohibiting transfer until such time as the vesting conditions with respect to such share have been satisfied (the “Transfer Restriction”). Any attempted transfer in violation of the Transfer Restriction shall be void ab initio. For the avoidance of doubt, the Company, Parent, SpinCo and any other applicable withholding agent shall each be entitled to deduct and withhold from any amounts payable or distributions made in respect of the Earnout Shares.

Continental Stock Transfer & Trust Company, as trustee (the “Trustee”) (the “Trust Agreement”). There are no separate Contracts, side letters or other arrangements or understandings (whether written or unwritten, express or implied) that would cause the description of the Trust Agreement in the Parent SEC Filings to be inaccurate or that would entitle any Person (other than the Parent Shareholders holding shares of Parent Common Stock sold in Parent’s initial public offering who shall have elected to redeem their shares of Parent Common Stock pursuant to Parent’s Governing Documents and the underwriters of Parent’s initial public offering with respect to deferred underwriting commissions) to any portion of the proceeds in the Trust Account. Prior to the Closing, none of the funds held in the Trust Account may be released other than (i) to pay Taxes and (ii) payments with respect to all Parent Share Redemptions. There are no claims or proceedings pending or, to the Knowledge of Parent, threatened with respect to the Trust Account. Parent has performed all material obligations required to be performed by it to date under, and is not in material default, breach or delinquent in performance or any other respect (claimed or actual) in connection with, the Trust Agreement, and no event has occurred which, with due notice or lapse of time or both, would constitute such a default or breach thereunder. As of the Effective Time, the obligations of Parent to dissolve or liquidate pursuant to Parent’s Governing Documents shall terminate, and as of the Effective Time, Parent shall have no obligation whatsoever pursuant to Parent’s Governing Documents to dissolve and liquidate the assets of Parent by reason of the consummation of the Transactions. To Parent’s Knowledge, as of the date hereof, following the Effective Time, no shareholder of Parent shall be entitled to receive any amount from the Trust Account except to the extent such shareholder of Parent is exercising a Parent Share Redemption. As of the date hereof, assuming the accuracy of the representations and warranties of the Company contained herein and the compliance by the Company and SpinCo with its obligations hereunder and under the other Transaction Documents, neither Parent or Merger Sub have any reason to believe that any of the conditions to the use of funds in the Trust Account will not be satisfied or funds available in the Trust Account will not be available to Parent and Merger Sub on the Closing Date.

Section 7.3 Tax Matters.

(a) This Agreement is intended to constitute a “plan of reorganization” for purposes of Section 368 of the Code and the Parties hereby adopt it as such. From and after the date of this Agreement and until the Effective Time, each Party shall use its reasonable best efforts to (A) ensure that (i) the Domestication will qualify as a “reorganization” within the meaning of Section 368(a)(1)(F), (ii) the Contribution and Distribution, taken together, will qualify as a “reorganization” within the meaning of Sections 368(a)(1)(D) and 355(a) of the Code, (iii) the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code and (iv) the Merger (taking into account the PIPE Investment) will not cause Section 355(e) of the Code to apply to the Distribution (with respect clauses (ii)-(iv), the “Tax-Free Status”) and (B) not take any action, cause or permit any action to be taken, fail to take any action or cause any action to fail to be taken, which action or failure to act could prevent (i) the Domestication from qualifying as a “reorganization” within the meaning of Section 368(a)(1)(F) or (ii) the Tax-Free Status. Following the Effective Time, none of the Company, Parent or any of their respective Affiliates shall take any action, cause or permit any action to be taken, fail to take any action or cause any action to fail to be taken, which action or failure to act could prevent the Tax-Free Status.

(b) Each of the Company, SpinCo and Parent shall cooperate with one another and shall use its reasonable best efforts for the Company to obtain a written opinion of LW, reasonably satisfactory in form and substance to the Company (the “Company Distribution Tax Opinion”), dated as of the Closing Date, to the effect that, on the basis of the facts, customary representations and assumptions set forth or referred to in such opinion, (i) the Contribution and Distribution, taken together, will qualify as a “reorganization” within the meaning of Sections 368(a)(1)(D) and 355(a) of the Code and (ii) the Merger will not cause Section 355(e) of the Code to apply to the Distribution. In delivering the Company Distribution Tax Opinion, LW shall be entitled to receive and rely upon the Parent Distribution Tax Representations and the Company Distribution Tax Representations.

(c) Company and SpinCo, on the one hand, and Parent, on the other hand, shall cooperate with one another in obtaining, and shall use their respective reasonable best efforts to obtain, a written opinion of LW (the “Company Merger Tax Opinion”), in the case of Company and SpinCo, and a written opinion of Weil (the “Parent Merger Tax Opinion”), in the case of Parent, reasonably satisfactory in form and substance to the Company and Parent, respectively, dated as of the Closing Date, to the effect that, on the basis of the facts, customary representations and assumptions set forth or referred to in such opinion, the Merger will be treated as a “reorganization” within the meaning of Section 368(a) of the Code. In delivering the Company Merger Tax Opinion and the Parent Merger Tax Opinion, LW and Weil shall both be entitled to receive and rely upon the SpinCo Merger Tax Representations and the Parent Merger Tax Representations.

-75-

(d) Company and SpinCo, on the one hand, and Parent, on the other hand, shall cooperate with one another in obtaining, and Parent shall use its reasonable best efforts to obtain a written opinion of Weil (the “Parent Domestication Tax Opinion”) reasonably satisfactory in form and substance to Parent, dated as of the Closing Date, to the effect that, on the basis of the facts, customary representations and assumptions set forth or referred to in such opinion, the Domestication will qualify as a “reorganization” under Section 368(a)(1)(F) of the Code. In delivering the Parent Domestication Tax Opinion, Weil shall be entitled to receive and rely upon representations, as necessary, of an officer of each of the Company, SpinCo and Parent dated as of the Closing Date, in form and substance reasonably satisfactory to Weil and delivered to Weil in connection with the Domestication. For the avoidance of doubt, the receipt of the Parent Domestication Tax Opinion is not a condition to closing under Article VIII.

(e) The Company and SpinCo, on the one hand, and Parent, on the other hand, shall cooperate with each other in obtaining, and shall use their respective reasonable best efforts to obtain, any Tax opinions required to be filed with the SEC in connection with the filing of the Parent Registration Statement and shall each use its respective reasonable best efforts to cause such opinions to be timely filed.

(f) Parent will promptly notify the Company if, before the Effective Time, it knows or has reason to believe that Parent is not reasonably expected to be able to obtain the Parent Merger Tax Opinion.

(g) The Company will promptly notify Parent if, before the Effective Time, it knows or has reason to believe that the Company is not reasonably expected to be able to obtain any of the Company Tax Opinions.

As promptly as practicable after the Parent Registration Statement and the SpinCo Registration Statement shall have become effective, each of the Company and Parent, as applicable, shall cause the Distribution Documents or the Parent Registration Statement (which shall include the Proxy Statement), as applicable, to be mailed or made available to the Company’s stockholders or the Parent’s stockholders, as applicable, in each case, pursuant to applicable Law. No filing of, or amendment or supplement to, the Parent Registration Statement or the Proxy Statement will be made by Parent without providing the Company and SpinCo with a reasonable opportunity to review and comment thereon (and such comments shall be reasonably considered by Parent in good faith).

(a) by mutual written agreement of the Company and Parent;

(b) by the Company or Parent, if the Closing shall not have occurred on or prior to the date that is nine (9) months after the date of this Agreement (the “Outside Date”); provided, that the right to terminate this Agreement pursuant to this Section 9.1(b) shall not be available to any Party whose action or failure to comply with its obligations under this Agreement or any of the other Transaction Documents has been the primary cause of, or has primarily resulted in, the failure of the Closing to occur on or prior to such date;

The Confidentiality Agreement shall not be affected by any termination of this Agreement.

Section 9.3 Termination Fee.

(a) In the event that this Agreement is terminated pursuant to Section 9.1(i), concurrently with such termination, the Company shall be obligated to pay Parent or its designee(s) a termination fee of (i) if terminated within 60 days of the date of this Agreement, $40,000,000, (ii) if terminated between 61 and 120 days after the date of this Agreement, $50,000,000, and (iii) if terminated between 121 and 180 days after the date of this Agreement, $70,000,000 (each such amount, the “Termination Fee”), by wire transfer of immediately available funds to an account designated by Parent in writing.

(b) In addition to payment of the Termination Fee, in the event that this Agreement is terminated pursuant to Section 9.1(i), the Company also shall pay the Parent Expenses (the “Parent Expenses Reimbursement”) by wire transfer of immediately available funds to an account designated by Parent in writing no later than two (2) Business Days after the date on which Parent delivers to the Company a written invoice for the Parent Expenses. As used herein, “Parent Expenses” means the amount of all reasonable and documented out-of-pocket fees and expenses, but not to exceed $7,500,000, incurred or paid by Parent and its Affiliates in connection with this Agreement and the Transactions, including fees and expenses of law firms, accounting firms, financial advisors, outside experts and consultants.

(c) Notwithstanding anything to the contrary set forth in this Agreement, except in the case of Actual Fraud or Willful Breach, if the Termination Fee and the Parent Expenses Reimbursement are paid pursuant to Section 9.3(a) and Section 9.3(b), respectively, such payment(s) shall constitute the sole and exclusive remedy of Parent, Merger Sub, any of their respective Subsidiaries or any of their respective former, current or future general or limited partners, shareholders, Representatives or assignees against the Company, SpinCo, any of their respective Subsidiaries and any of their respective former, current or future general or limited partners, shareholders, Representatives or assignees (together with the Company, collectively, the “Company Related Parties”) for all losses and damages suffered as a result of the failure of the Transactions to be consummated or for a breach or failure to perform hereunder or otherwise, and none of the Company Related Parties shall have any further liability or obligation relating to or arising out of this Agreement or the Transactions.

-94-

(d) If the Company fails to pay promptly any amount due under this Section 9.3, as applicable, and in order to obtain such payment, the Parent commences an Action that results in a judgment against the Company for any amount owed thereby under this Section 9.3, as applicable, the Company shall reimburse Parent for its reasonable and documented costs and expenses (including reasonable and documented attorneys’ fees) in connection with such Action, together with interest on such amount at a rate equal to (x) the prime rate as published in The Wall Street Journal in effect on the date such payment was required to be made through the date such payment was actually received, plus (y) five percent (5%).

(e) Each of the Parties acknowledges that (i) the agreements contained in this Section 9.3 are an integral part of the Transactions, (ii) without these agreements, the Parties would not enter into this Agreement and (iii) the Termination Fee does not constitute a penalty, but rather is liquidated damages in a reasonable amount that will compensate Parent for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions, which amount would otherwise be impossible to calculate with precision.

Section 9.4 Fees and Expenses. Except as otherwise provided in the Separation and Distribution Agreement or this Agreement, including this Section 9.4, and except for filing fees payable to any Governmental Authority in connection with the approvals required under Section 7.5(b), which shall be borne equally by the Company and Parent in the event that this Agreement is terminated in accordance with its terms and by SpinCo in the event that the Closing occurs, all fees and expenses incurred by the Parties shall be borne solely by the Party that has incurred such fees and expenses, whether or not the Merger is consummated.

ARTICLE X

MISCELLANEOUS

Section 10.1 Trust Account Waiver. The Company acknowledges that Parent is a blank check company with the powers and privileges to effect a Business Combination. The Company further acknowledges that, as described in the prospectus dated August 9, 2021 (the “Prospectus”) available at www.sec.gov, substantially all of Parent’s assets consist of the cash proceeds of Parent’s initial public offering and private placements of its securities and substantially all of those proceeds have been deposited in a trust account for the benefit of Parent, certain of its public stockholders and the underwriters of Parent’s initial public offering (the “Trust Account”). The Company acknowledges that it has been advised by Parent that, except with respect to interest earned on the funds held in the Trust Account that may be released to Parent to pay its franchise Tax, income Tax and similar obligations, the Trust Agreement provides that cash in the Trust Account may be disbursed only (i) if Parent completes one or more transactions that constitute a Business Combination, then to those Persons and in such amounts as described in the Prospectus; (ii) if Parent fails to complete a Business Combination within the allotted time period and liquidates, subject to the terms of the Trust Agreement, to

-95-

Parent in limited amounts to permit Parent to pay the costs and expenses of its liquidation and dissolution, and then to Parent’s public stockholders; and (iii) if Parent holds a shareholder vote to amend Parent’s amended and restated memorandum and articles of association to modify the substance or timing of the obligation to redeem 100% of the shares of Parent Common Stock if Parent fails to complete a Business Combination within the allotted time period, then for the redemption of any shares of Parent Common Stock properly tendered in connection with such vote. For and in consideration of Parent entering into this Agreement, the receipt and sufficiency of which are hereby acknowledged, the Company hereby irrevocably waives any right, title, interest or claim of any kind it has or may have in the future in or to any monies in the Trust Account (including any distributions therefrom) and agrees not to seek recourse against the Trust Account or any funds distributed therefrom as a result of, or arising out of, this Agreement and any negotiations, Contracts or agreements with Parent; provided, (x) that nothing herein shall serve to limit or prohibit the Company’s right to pursue a claim against Parent for legal relief against monies or other assets held outside the Trust Account, for specific performance or other equitable relief in connection with the consummation of the Transactions (including a claim for Parent to specifically perform its obligations under this Agreement and cause the disbursement of the balance of the cash remaining in the Trust Account (after giving effect to the Parent Share Redemptions) to Parent in accordance with the terms of this Agreement and the Trust Agreement) so long as such claim would not affect Parent’s ability to fulfill its obligation to effectuate the Parent Share Redemptions, and (y) nothing herein shall serve to limit or prohibit any claims the Company may have in the future against Parent’s assets or funds that are not held in the Trust Account (including any funds that have been released from the Trust Account to Parent and any assets that have been purchased or acquired with any such funds). The Company agrees and acknowledges that such irrevocable waiver is material to this Agreement and specifically relied upon by Parent to induce it to enter in this Agreement, and the Company further intends and understands such waiver to be valid, binding and enforceable under applicable Law. To the extent the Company commences any Action or proceeding based upon, in connection with, relating to or arising out of any matter relating to Parent, which proceeding seeks, in whole or in part, monetary relief against Parent, the Company hereby acknowledges and agrees that its sole remedy shall be against funds held outside of the Trust Account and that such claim shall not permit the Company (or any party claiming on the Company’s behalf or in lieu of the Company) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein. In the event that the Company commences any Action or proceeding based upon, in connection with, relating to or arising out of any matter relating to Parent, which proceeding seeks, in whole or in part, relief against the Trust Account (including any distributions therefrom) or the holders of Parent Common Stock, whether in the form of money damages or injunctive relief, the prevailing party shall be entitled to recover from the other party the associated legal fees and costs in connection with any such Action.

Section 10.2 Non-Survival of Representations, Warranties and Agreements. The obligations, covenants and agreements that by their terms are to be performed following the Closing pursuant to any Transaction Document, including the Separation and Distribution Agreement, or this Agreement shall survive the Effective Time in accordance with their terms and all other obligations, covenants and agreements herein and therein shall terminate and shall not survive the Closing. None of the representations or warranties in this Agreement or in any certificate or instrument delivered pursuant to this Agreement shall survive the Effective Time. The Confidentiality Agreement shall survive the execution and delivery of this Agreement and

-96-

any termination of this Agreement, and the provisions of the Confidentiality Agreement shall apply to all information and material furnished by any Party or its Representatives thereunder or hereunder; provided, that, following the Effective Time, Parent shall have no obligations under the Confidentiality Agreement with respect to information related solely to the SpinCo Entities, the SpinCo Business or the SpinCo Assets, which information shall no longer be considered “Evaluation Material” for purposes thereof.

Section 10.3 Governing Law; Jurisdiction. This Agreement, and all claims, disputes, controversies or causes of action (whether in contract, tort, equity or otherwise) that may be based upon, arise out of or relate to this Agreement (including any schedule or exhibit hereto) or the negotiation, execution or performance of this Agreement (including any claim, dispute, controversy or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement), shall be governed by and construed in accordance with the Laws of the State of Delaware, without regard to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware; provided, that the Domestication shall be effected in accordance with both the DGCL and the CICA (as applicable), without giving effect to principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of Laws of another jurisdiction. Each of the Parties agrees that any Action related to this agreement shall be brought exclusively in the Court of Chancery of the State of Delaware or, if under applicable Law, exclusive jurisdiction over such matter is vested in the federal courts, any federal court in the State of Delaware and any appellate court from any thereof (the “Chosen Courts”). By executing and delivering this Agreement, each of the Parties irrevocably: (i) accepts generally and unconditionally submits to the exclusive jurisdiction of the Chosen Courts for any Action relating to this Agreement, including any Action brought for any remedy contemplated by Section 10.9; (ii) waives any objections which such party may now or hereafter have to the laying of venue of any such Action contemplated by this Section 10.3 and hereby further irrevocably waives and agrees not to plead or claim that any such Action has been brought in an inconvenient forum; (iii) agrees that it will not attempt to deny or defeat the personal jurisdiction of the Chosen Courts by motion or other request for leave from any such court; (iv) agrees that it will not bring any Action contemplated by this Section 10.3 in any court other than the Chosen Courts; (v) agrees that service of all process, including the summons and complaint, in any Action may be made by registered or certified mail, return receipt requested, to such party at their respective addresses provided in accordance with Section 10.4 or in any other manner permitted by Law; and (vi) agrees that service as provided in the preceding clause (v) is sufficient to confer personal jurisdiction over such party in the Action, and otherwise constitutes effective and binding service in every respect. Each of the parties hereto agrees that a final judgment in any Action in a Chosen Court as provided above may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law, and each party further agrees to the non-exclusive jurisdiction of the Chosen Courts for the enforcement or execution of any such judgment.

ARTICLE II

THE SEPARATION

Section 2.1 General. Subject to the terms and conditions of this Agreement, the Parties shall use, and shall cause their respective Affiliates to use, their respective commercially reasonable efforts to consummate the transactions contemplated hereby, including the completion of the Internal Reorganization, a portion of which may have already been implemented prior to the date hereof.

Section 2.2 Restructuring: Transfer of Assets; Assumption of Liabilities.

(a) Internal Reorganization. Prior to the Distribution Time, except for Transfers contemplated by the Internal Reorganization or this Agreement or the Ancillary Agreements to occur after the Distribution Time, the Parties shall complete the Internal Reorganization, including by taking the actions referred to in Sections 2.2(b) and 2.2(c) below.

(b) Transfer of Assets. At or prior to the Distribution Time (it being understood that some of such Transfers may occur following the Distribution Time in accordance with Section 2.2(a) and Section 2.6), pursuant to the Conveyancing and Assumption Instruments and in connection with the Contribution:

(i) Ligand shall, and shall cause the applicable Asset Transferors to, transfer, contribute, distribute, assign and/or convey or cause to be transferred, contributed, distributed, assigned and/or conveyed (“Transfer”) to OmniAb and/or the respective OmniAb Asset Transferees, all of its and the applicable Asset Transferors’ right, title and interest in and to the OmniAb Assets, and the applicable OmniAb Asset Transferees shall accept from Ligand and the applicable members of the Ligand Group all of Ligand’s and the other members of the Ligand Group’s respective direct or indirect rights, title and interest in and to the applicable Assets, including all of the outstanding shares of capital stock or other ownership interests, that are included in the OmniAb Assets.

(ii) Any costs and expenses incurred after the Distribution Time to effect any Transfer contemplated by this Section 2.2(b) (including any transfer effected pursuant to Section 2.6) shall be paid by the Parties as set forth in Section 9.5. Other than costs and expenses incurred in accordance with the foregoing sentence, nothing in this Section 2.2(b) shall require any member of any Group to incur any material obligation or grant any material concession for the benefit of any member of any other Group in order to effect any transaction contemplated by this Section 2.2(b).

For the avoidance of doubt any OmniAb Assets already held by OmniAb prior to the Internal Reorganization shall not need to be Transferred and shall remain with OmniAb prior to and following the Distribution Time.

(c) Assumption of Liabilities. Except as pursuant to this Agreement or as otherwise specifically set forth in any Ancillary Agreement, in connection with the Internal Reorganization and the Contribution or, if applicable, from and after, the Distribution Time (i) pursuant to this Agreement or the applicable Conveyancing and Assumption Instruments, OmniAb shall, or shall cause a member of the OmniAb Group to accept, assume (or, as applicable, retain) and perform, discharge and fulfill, in accordance with their respective terms (“Assume”), all of the OmniAb Liabilities and (ii) pursuant to this Agreement or the applicable Conveyancing and Assumption Instruments, Ligand shall, or shall cause a member of the Ligand Group to, Assume all of the Ligand Retained Liabilities, in each case, regardless of (A) when or where such Liabilities arose or arise, (B) whether the facts upon which they are based occurred prior to, at or subsequent to the Distribution Time, (C) whether accruals for such Liabilities have been transferred to OmniAb or included on a combined balance sheet of the OmniAb Business or whether any such accruals are sufficient to cover such Liabilities, (D) where or against whom such Liabilities are asserted or determined, (E) whether arising from or alleged to arise from negligence, gross negligence, recklessness, violation of Law, fraud or misrepresentation by any member of the Ligand Group or the OmniAb Group, as the case may be, or any of their past or present respective directors, officers, employees, agents, Subsidiaries or Affiliates, (F) which entity is named in any Action associated with any Liability, or (G) any benefits, or lack thereof, that have been or may be obtained by the Ligand Group or the OmniAb Group in respect of such Liabilities.

(d) Consents. The Parties shall use their commercially reasonable efforts to obtain the Consents required to Transfer any Assets, Contracts, licenses, permits and authorizations issued by any Governmental Entity or parts thereof as contemplated by this Agreement. Notwithstanding anything herein to the contrary, no Contract or other Asset shall be transferred if it would violate applicable Law or, in the case of any Contract, the rights of any third party to such Contract; provided that Section 2.6, to the extent provided therein, shall apply thereto. The foregoing shall not preclude OmniAb or any member of the OmniAb Group from disputing in good faith with any third party (other than Ligand or any member of the Ligand Group) the validity of any OmniAb Liabilities or raising any available defenses in connection therewith.

(e) It is understood and agreed by the Parties that certain of the Transfers referenced in Section 2.2(b) or Assumptions referenced in Section 2.2(c) have occurred prior to the date hereof and, as a result, no additional Transfers or Assumptions by any member of the Ligand Group or the OmniAb Group, as applicable, shall be deemed to occur upon the execution of this Agreement with respect thereto. Moreover, to the extent that any member of the Ligand Group or the OmniAb Group, as applicable, is liable for any Ligand Retained Liability or OmniAb Liability, respectively, by operation of law immediately following any Transfer in accordance with this Agreement or any Conveyancing and Assumption Instruments, there shall be no need for any other member of the Ligand Group or the OmniAb Group, as applicable, to Assume such Liability in connection with the operation of Section 2.2(c) and, accordingly, no other member of such Group shall Assume any such Liability in connection with Section 2.2(c).

Section 2.3 Treatment of Shared Contracts. Without limiting the generality of the obligations set forth in Sections 2.2(a) and (b):

(a) Unless the Parties otherwise agree or the benefits of any Contract described in this Section 2.3 are expressly conveyed to the applicable Party pursuant to an Ancillary Agreement, and other than as provided by Article VIII, any Contract that is listed on Schedule 2.3(a) (a “Shared Contract”) shall be assigned in part to the applicable member(s) of the applicable Group, if so assignable, or appropriately amended prior to, at or after the Distribution Time, so that each Party or the members of their respective Groups as of the Distribution Time shall be entitled to the rights and benefits, and shall Assume the related portion of any Liabilities, inuring to their respective Businesses; provided, however, that (x) in no event shall any member of any Group be required to assign (or amend) any Shared Contract in its entirety or to assign a portion of any Shared Contract which is not assignable (or cannot be amended) by its terms (including any terms imposing consents or conditions on an assignment where such consents or conditions have not been obtained or fulfilled, subject to Section 2.2(d)), and (y) if any Shared Contract cannot be so partially assigned by its terms or otherwise, cannot be amended or has not for any other reason been assigned or amended, or if such assignment or amendment would impair the benefit the parties thereto derive from such Shared Contract, (A) at the reasonable request of the Party (or the member of such Party’s Group) to which the benefit of such Shared Contract inures in part, the Party for which such Shared Contract is, as applicable, a Ligand Retained Asset or OmniAb Asset shall, and shall cause each of its respective Subsidiaries

to, for a period ending not later than six (6) months after the Distribution Date (unless the term of a Shared Contract (excluding any extensions thereof) ends at a later date, in which case for a period ending on such date), take such other reasonable and permissible actions to cause such member of the OmniAb Group or the Ligand Group, as the case may be, to receive the benefit of that portion of each Shared Contract that relates to the OmniAb Business or the Ligand Retained Business, as the case may be (in each case, to the extent so related) as if such Shared Contract had been assigned to (or amended to allow) a member of the applicable Group pursuant to this Section 2.3 and to bear the burden of the corresponding Liabilities (including any Liabilities that may arise by reason of such arrangement) as if such Liabilities had been Assumed by a member of the applicable Group pursuant to this Section 2.3; provided that the Party for which such Shared Contract is a Ligand Retained Asset or an OmniAb Asset, as applicable, shall be indemnified for all Indemnifiable Losses or other Liabilities arising out of any actions (or omissions to act) of such retaining Party taken at the direction of the other Party (or relevant member of its Group) in connection with and relating to such Shared Contract, as the case may be, and (B) the Party to which the benefit of such Shared Contract inures in part shall use commercially reasonable efforts to enter into a separate contract pursuant to which it procures such rights and obligations as are necessary such that it no longer needs to avail itself of the arrangements provided pursuant to this Section 2.3(a); provided that, the Party for which such Shared Contract is, as applicable, a Ligand Retained Asset or OmniAb Asset, any such Party’s applicable Subsidiaries shall not be liable for any actions or omissions taken in accordance with clause (y) of this Section 2.3(a).

(b) Unless the Parties otherwise agree, each of Ligand and OmniAb shall, and shall cause the members of its Group to, (A) treat for all Tax purposes the portion of each Shared Contract inuring to its respective Businesses as Assets owned by, and/or Liabilities of, as applicable, such Party as of the Distribution Time and (B) neither report nor take any Tax position (on a Tax Return or otherwise) inconsistent with such treatment (unless required by applicable Law or good faith resolution of a Tax Contest).

Section 2.4 Intercompany Accounts, Loans and Agreements.

(a) Except as set forth in Section 5.1(b), all intercompany receivables and payables (other than (x) intercompany loans (which shall be governed by Section 2.4(c)), and (y) payables created or required by this Agreement, any Ancillary Agreement or any Continuing Arrangements) and intercompany balances, including in respect of any cash balances, any cash balances representing deposited checks or drafts or any cash held in any centralized cash management system between any member of the Ligand Group, on the one hand, and any member of the OmniAb Group, on the other hand, which exist and are reflected in the accounting records of the relevant Parties immediately prior to the Distribution Time, shall be paid, performed or otherwise settled on or prior to the Distribution Time, and all arrangements, understandings and agreements relating thereto are hereby terminated.

(b) As between the Parties (and the members of their respective Group) all payments and reimbursements received after the Distribution Time by one Party (or member of its Group) that relate to a Business, Asset or Liability of the other Party (or member of its Group), shall be held by such Party in trust for the use and benefit of the Party entitled thereto (at the expense of the Party entitled thereto) and, promptly upon receipt by such Party of any such

payment or reimbursement, such Party shall pay or shall cause the applicable member of its Group to pay over to the Party entitled thereto the amount of such payment or reimbursement without right of set-off.

(c) Each of Ligand or any member of the Ligand Group, on the one hand, and OmniAb or any member of the OmniAb Group, on the other hand, will settle with the other Party, as the case may be, all intercompany loans, including any promissory notes, owned or owed by the other Party on or prior to the Distribution Time, it being understood and agreed by the Parties that all guarantees and Credit Support Instruments shall be governed by Section 2.10.

Section 2.5 Limitation of Liability; Intercompany Contracts. No Party nor any Subsidiary thereof shall be liable to the other Party or any Subsidiary of the other Party based upon, arising out of or resulting from any Contract, arrangement, course of dealing or understanding between or among it and the other Party existing at or prior to the Distribution Time (other than pursuant to this Agreement, any Ancillary Agreement, any Continuing Arrangements, any Third Party Agreements, or pursuant to any other Contract entered into in connection herewith or in order to consummate the transactions contemplated hereby or thereby) and each Party hereby terminates any and all Contracts, arrangements, courses of dealing or understandings between or among it and the other Party effective as of the Distribution Time (other than as set forth in this Agreement, any Ancillary Agreement, any Continuing Arrangements, any Third Party Agreements, or pursuant to any Contract entered into in connection herewith or in order to consummate the transactions contemplated hereby or thereby), provided, however, that with respect to any Contract, arrangement, course of dealing or understanding between or among the Parties or any Subsidiaries thereof discovered after the Distribution Time, the Parties agree that such Contract, arrangement, course of dealing or understanding shall nonetheless be deemed terminated as of the Distribution Time with the only liability of the Parties in respect thereof to be the obligations incurred between the Parties pursuant to such Contract, arrangement, course of dealing or understanding between the Distribution Time and the time of discovery or later termination of any such Contract, arrangement, course of dealing or understanding.

Section 2.6 Transfers Not Effected at or Prior to the Distribution Time; Transfers Deemed Effective as of the Distribution Time.

(a) To the extent that any Transfers or Assumptions contemplated by this Article II shall not have been consummated at or prior to the Distribution Time, the Parties shall use commercially reasonable efforts (taking into account any applicable restrictions or considerations, in each case relating to the contemplated Tax treatment of the transactions contemplated hereby) to effect such Transfers or Assumptions as promptly following the Distribution Time as shall be practicable. Nothing herein shall be deemed to require or constitute the Transfer of any Assets or the Assumption of any Liabilities which by their terms or operation of Law cannot be Transferred; provided, however, that the Parties and their respective Subsidiaries shall cooperate and use commercially reasonable efforts to seek to obtain, in accordance with applicable Law, any necessary Consents or Governmental Approvals for the Transfer of all Assets and Assumption of all Liabilities contemplated to be Transferred and Assumed pursuant to this Article II to the fullest extent permitted by applicable Law. In the event that any such Transfer of Assets or Assumption of Liabilities has not been consummated,

from and after the Distribution Time, (i) the Party (or relevant member in its Group) retaining such Asset shall thereafter hold (or shall cause such member in its Group to hold) such Asset in trust for the use and benefit of the Party entitled thereto (at the expense of the Party entitled thereto) and (ii) the Party intended to Assume such Liability shall, or shall cause the applicable member of its Group to, pay or reimburse the Party retaining such Liability for all amounts paid or incurred in connection with the retention of such Liability. To the extent the foregoing applies to any Contracts (other than Shared Contracts, which shall be governed solely by Section 2.3) to be assigned for which any necessary Consents or Governmental Approvals are not received prior to the Distribution Time, the treatment of such Contracts shall, for the avoidance of doubt, be subject to Section 2.8 and Section 2.9, to the extent applicable. In addition, the Party retaining such Asset or Liability (or relevant member of its Group) shall (or shall cause such member in its Group to) treat, insofar as reasonably possible and to the extent permitted by applicable Law, such Asset or Liability in the ordinary course of business in accordance with past practice and take such other actions as may be reasonably requested by the Party to which such Asset is to be Transferred or by the Party Assuming such Liability in order to place such Party, insofar as reasonably possible and to the extent permitted by applicable Law, in the same position as if such Asset or Liability had been Transferred or Assumed as contemplated hereby and so that all the benefits and burdens relating to such Asset or Liability, including possession, use, risk of loss, potential for income and gain, and dominion, control and command over such Asset or Liability, are to inure from and after the Distribution Time to the relevant member or members of the Ligand Group or the OmniAb Group entitled to the receipt of such Asset or required to Assume such Liability. In furtherance of the foregoing, the Parties agree that, as of the Distribution Time, subject to Section 2.2(c) and Section 2.9(b), each Party shall be deemed to have acquired complete and sole beneficial ownership over all of the Assets, together with all rights, powers and privileges incident thereto, and shall be deemed to have Assumed in accordance with the terms of this Agreement all of the Liabilities, and all duties, obligations and responsibilities incident thereto, which such Party is entitled to acquire or required to Assume pursuant to the terms of this Agreement.

(b) If and when the Consents, Governmental Approvals and/or conditions, the absence or non-satisfaction of which caused the deferral of Transfer of any Asset or deferral of the Assumption of any Liability pursuant to Section 2.6(a), are obtained or satisfied, the Transfer, assignment, Assumption or novation of the applicable Asset or Liability shall be effected without further consideration in accordance with and subject to the terms of this Agreement (including Section 2.2) and/or the applicable Ancillary Agreement, and shall, to the extent possible without the imposition of any undue cost on any Party, be deemed to have become effective as of the Distribution Time.

(c) The Party (or relevant member of its Group) retaining any Asset or Liability due to the deferral of the Transfer of such Asset or the deferral of the Assumption of such Liability pursuant to Section 2.6(a) or otherwise shall (i) not be obligated, in connection with the foregoing, to expend any money unless the necessary funds are advanced, assumed, or agreed in advance to be reimbursed by the Party (or relevant member of its Group) entitled to such Asset or the Person intended to be subject to such Liability, other than reasonable attorneys’ fees and recording or similar or other incidental fees, all of which shall be promptly reimbursed by the Party (or relevant member of its Group) entitled to such Asset or the Person intended to be subject to such Liability and (ii) be indemnified for all Indemnifiable Losses or other Liabilities arising out of any actions (or omissions to act) of such retaining Party taken at the direction of the other Party (or relevant member of its Group) in connection with and relating to such retained Asset or Liability, as the case may be.

(d) After the Distribution Time, each Party (or any member of its Group) may receive mail, packages, electronic mail or other electronic communications and any other written communications properly belonging to another Party (or any member of its Group). Accordingly, at all times after the Distribution Time, each Party is hereby authorized to receive and, if reasonably necessary to identify the proper recipient in accordance with this Section 2.6(d), open all mail, packages, electronic mail or other electronic communication and any other written communications received by such Party that belongs to such other Party, and to the extent that they do not relate to the business of the receiving Party, the receiving Party shall promptly deliver such mail, packages, electronic mail or other electronic communication or any other written communications (or, in case the same also relates to the business of the receiving Party or another Party, copies thereof) to such other Party as provided for in Section 9.6; it being understood that if a Party receives a telephone call that relates to the business of the other Party, then the receiving Party shall inform the person making such telephone call to contact the other Party. The provisions of this Section 2.6(d) are not intended to, and shall not, be deemed to constitute an authorization by any Party to permit the other to accept service of process on its behalf and no Party is or shall be deemed to be the agent of any other Party for service of process purposes.

(e) With respect to Assets and Liabilities described in Section 2.6(a), each of Ligand and OmniAb shall, and shall cause the members of its respective Group to, (i) treat for all Tax purposes (A) the deferred Assets as assets having been Transferred to and owned by the Party entitled to such Assets not later than the Distribution Time and (B) the deferred Liabilities as liabilities having been Assumed and owned by the Person intended to be subject to such Liabilities not later than the Distribution Time and (ii) neither report nor take any Tax position (on a Tax Return or otherwise) inconsistent with such treatment (unless required by applicable Law or good faith resolution of a Tax Contest).

Section 2.7 Conveyancing and Assumption Instruments. In connection with, and in furtherance of, the Transfers of Assets and the Assumptions of Liabilities contemplated by this Agreement, the Parties shall execute or cause to be executed, on or after the date hereof by the appropriate entities to the extent not executed prior to the date hereof, any Conveyancing and Assumption Instruments necessary to evidence the valid Transfer to the applicable Party or member of such Party’s Group of all right, title and interest in and to its accepted Assets and the valid and effective Assumption by the applicable Party of its Assumed Liabilities for Transfers and Assumptions to be effected pursuant to Delaware Law or the Laws of one of the other states of the United States or, if not appropriate for a given Transfer or Assumption, and for Transfers or Assumptions to be effected pursuant to non-U.S. Laws, in such form as the Parties shall reasonably agree, including the Transfer of real property by mutually acceptable conveyance deeds as may be appropriate and in form and substance as may be required by the jurisdiction in which the real property is located; provided, that the allocation of Assets and Liabilities provided for in any Conveyancing and Assumption Instruments shall be consistent with the terms of this Agreement, unless otherwise approved in writing by the Parties and APAC . The Transfer of capital stock shall, to the extent necessary to evidence a valid Transfer, be effected by means of executed stock powers and notation on the stock record books of the corporation or other legal entities involved, or by such other means as may be required in any non-U.S. jurisdiction to Transfer title to stock and, only to the extent required by applicable Law, by notation on public registries.

Section 2.8 Further Assurances; Ancillary Agreements.

(a) In addition to and without limiting the actions specifically provided for elsewhere in this Agreement and subject to the limitations expressly set forth in this Agreement, including Section 2.6, each of the Parties shall cooperate with each other and use (and shall cause its respective Subsidiaries and Affiliates to use) commercially reasonable efforts, at and after the Distribution Time, to take, or to cause to be taken, all actions, and to do, or to cause to be done, all things reasonably necessary on its part under applicable Law or contractual obligations to consummate and make effective the transactions contemplated by this Agreement and the Ancillary Agreements.

(b) Without limiting the foregoing, at and after the Distribution Time, each Party shall cooperate with the other Party, and without any further consideration, but at the expense of the requesting Party (except as provided in Sections 2.2(b)(ii) and 2.6(c)) from and after the Distribution Time, to execute and deliver, or use commercially reasonable efforts to cause to be executed and delivered, all instruments, including instruments of Transfer or title, and to make all filings with, and to obtain all Consents and/or Governmental Approvals, any permit, license, Contract, indenture or other instrument (including any Consents or Governmental Approvals), and to take all such other actions as such Party may reasonably be requested to take by any other Party from time to time, consistent with the terms of this Agreement and the Ancillary Agreements, in order to effectuate the provisions and purposes of this Agreement and the Ancillary Agreements and the Transfers of the applicable Assets and the assignment and Assumption of the applicable Liabilities and the other transactions contemplated hereby and thereby. Without limiting the foregoing, each Party shall, at the reasonable request, cost and expense of any other Party (except as provided in Sections 2.2(b)(ii) and 2.6(c)), take such other actions as may be reasonably necessary to vest in such other Party such title and such rights as possessed by the transferring Party to the Assets allocated to such other Party under this Agreement or any of the Ancillary Agreements, free and clear of any Security Interest.

(c) Without limiting the foregoing, in the event that any Party (or member of such Party’s Group) receives or retains any Assets (including the receipt of payments made pursuant to Contracts and proceeds from accounts receivable with respect to such Asset) or is liable for any Liability that is otherwise allocated to any Person that is a member of the other Group pursuant to this Agreement or the Ancillary Agreements, such Party agrees to promptly Transfer, or cause to be Transferred such Asset or Liability to the other Party so entitled thereto (or member of such other Party’s Group as designated by such other Party) at such other Party’s expense. Prior to any such Transfer, such Asset or Liability, as the case may be, shall be held in accordance with the provisions of Section 2.6.

(a) Each Party, at the request of any member of the other Party’s Group (such other Party, the “Other Party”), shall use commercially reasonable efforts (taking into account any applicable restrictions or considerations, in each case relating to the contemplated Tax treatment of the transactions contemplated hereby) to obtain, or to cause to be obtained, any Consent, Governmental Approval, substitution or amendment required to novate or assign to the fullest extent permitted by applicable Law all obligations under Contracts (other than Shared Contracts, which shall be governed by Section 2.3) and Liabilities (other than with regard to guarantees or Credit Support Instruments, which shall be governed by Section 2.10), but solely to the extent that the Parties are jointly or each severally liable with regard to any such Contracts or Liabilities and such Contracts or Liabilities have been, in whole, but not in part, allocated to the first Party, or, if permitted by applicable Law, to obtain in writing the unconditional release of the applicable Other Party so that, in any such case, the members of the applicable Group shall be solely responsible for such Contracts or Liabilities; provided, however, that no Party shall be obligated to pay any consideration therefor to any third party from whom any such Consent, Governmental Approval, substitution or amendment is requested (unless such Party is fully reimbursed by the requesting Party). In addition, with respect to any Action where any Party hereto is a defendant, when and if requested by such Party, the Other Party at its own cost will use commercially reasonable efforts to remove the requesting Party as a defendant to the extent that such Action relates solely to Assets or Liabilities that the Other Party (or any member of such requesting Party’s Group) has been allocated pursuant to this Article II, and the Other Party will cooperate and assist in any required communication with any plaintiff or other related third party.

(b) If the Parties are unable to obtain, or to cause to be obtained, any such required Consent, Governmental Approval, release, substitution or amendment referenced in Section 2.9(a), the Other Party or a member of such Other Party’s Group shall continue to be bound by such Contract, license or other obligation that does not constitute a Liability of such Other Party and, unless not permitted by Law or the terms thereof, as agent or subcontractor for such Party, the Party or member of such Party’s Group who Assumed or retained such Liability as set forth in this Agreement (the “Liable Party”) shall, or shall cause a member of its Group to, pay, perform and discharge fully all the obligations or other Liabilities of such Other Party or member of such Other Party’s Group thereunder from and after the Distribution Time. For the avoidance of doubt, in furtherance of the foregoing, the Liable Party or a member of such Liable Party’s Group, as agent or subcontractor of the Other Party or a member of such Other Party’s Group, to the extent reasonably necessary to pay, perform and discharge fully any Liabilities, or retain the benefits (including pursuant to Section 2.6) associated with such Contract or license, is

hereby granted the right to, among other things, (i) prepare, execute and submit invoices under such Contract or license in the name of the Other Party (or the applicable member of such Other Party’s Group), (ii) send correspondence relating to matters under such Contract or license in the name of the Other Party (or the applicable member of such Other Party’s Group), (iii) file Actions in the name of the Other Party (or the applicable member of such Other Party’s Group) in connection with such Contract or license and (iv) otherwise exercise all rights in respect of such Contract or license in the name of the Other Party (or the applicable member of such Other Party’s Group); provided that (y) such actions shall be taken in the name of the Other Party (or the applicable member of such Other Party’s Group) only to the extent reasonably necessary or advisable in connection with the foregoing and (z) to the extent that there shall be a conflict between the provisions of this Section 2.9(b) and the provisions of any more specific arrangement between a member of such Liable Party’s Group and a member of such Other Party’s Group, such more specific arrangement shall control. The Liable Party shall indemnify each Other Party and hold each of them harmless against any Liabilities (other than Liabilities of such Other Party) arising in connection therewith; provided, that the Liable Party shall have no obligation to indemnify the Other Party with respect to any matter to the extent that such Liabilities arise from such Other Party’s willful breach, knowing violation of Law, fraud, misrepresentation or gross negligence in connection therewith, in which case such Other Party shall be responsible for such Liabilities; it being understood that any exercise of rights under this Agreement by such Other Party shall not be deemed to be willful breach, knowing violation of Law, fraud, misrepresentation or gross negligence. The Other Party shall, without further consideration, promptly pay and remit, or cause to be promptly paid or remitted, to the Liable Party or, at the direction of the Liable Party, to another member of the Liable Party’s Group, all money, rights and other consideration received by it or any member of its Group in respect of such performance by the Liable Party (unless any such consideration is an Asset of such Other Party pursuant to this Agreement). If and when any such Consent, Governmental Approval, release, substitution or amendment shall be obtained or such agreement, lease, license or other rights or obligations shall otherwise become assignable or able to be novated, the Other Party shall, to the fullest extent permitted by applicable Law, promptly Transfer or cause the Transfer of all rights, obligations and other Liabilities thereunder of such Other Party or any member of such Other Party’s Group to the Liable Party or to another member of the Liable Party’s Group without payment of any further consideration and the Liable Party, or another member of such Liable Party’s Group, without the payment of any further consideration, shall Assume such rights and Liabilities to the fullest extent permitted by applicable Law. Each of the applicable Parties shall, and shall cause their respective Subsidiaries to, take all actions and do all things reasonably necessary on its part, or such Subsidiaries’ part, under applicable Law or contractual obligations to consummate and make effective the transactions contemplated by this Section 2.9.

Notwithstanding the foregoing, nothing in this Agreement shall be deemed to limit APAC or any of its Affiliates from commencing any Actions against any Ligand officer, director, agent or employee, or their respective heirs, executors, administrators, successors and assigns with regard to matters arising from, or relating to, (i) theft of OmniAb Trade Secrets or (ii) intentional criminal acts by any such officers, directors, agents or employees.

(b) Nothing contained in this Agreement, including Section 5.1(a) or Section 2.5, shall impair or otherwise affect any right of any Party or APAC and, as applicable, a member of such Party’s Group or any of its Affiliates, as well as their respective heirs, executors, administrators, successors and assigns, to enforce this Agreement, the Merger Agreement any Ancillary Agreement or any agreements, arrangements, commitments or understandings contemplated in this Agreement, the Merger Agreement or in any Ancillary Agreement to continue in effect after the Distribution Time.

(iii) any Liability with respect to any Continuing Arrangements;

(v) the obligations of Ligand, OmniAb, APAC or the other parties to the Merger Agreement to consummate the Merger and the other transactions expressly contemplated to occur at the Closing, subject to the terms and conditions of the Merger Agreement; and

(vi) any Liability the release of which would result in a release of any Person other than the Persons released in Section 5.1(a); provided that the Parties and APAC agree not to bring any Action or permit any other member of their respective Group or any of their Affiliates to bring any Action against a Person released in Section 5.1(a) with respect to such Liability.

In addition, nothing contained in Section 5.1(a) shall release: (i) Ligand from indemnifying any director, officer or employee of the OmniAb Group who was a director, officer or employee of Ligand or any of its Affiliates prior to the Distribution Time, as the case may be, to the extent such director, officer or employee is or becomes a named defendant in any Action with respect to which he or she was entitled to such indemnification pursuant to then-existing obligations; it being understood that if the underlying obligation giving rise to such Action is an OmniAb Liability, OmniAb shall indemnify Ligand for such Liability (including Ligand’s costs to indemnify the director, officer or employee) in accordance with the provisions set forth in this Article V; and (ii) OmniAb from indemnifying any director, officer or employee of the Ligand Group who was a director, officer or employee of OmniAb or any of its Affiliates prior to the Distribution Time, as the case may be, to the extent such director, officer or employee is or becomes a named defendant in any Action with respect to which he or she was entitled to such indemnification pursuant to then-existing obligations; it being understood that if the underlying obligation giving rise to such Action is a Ligand Retained Liability, Ligand shall indemnify OmniAb for such Liability (including OmniAb’s costs to indemnify the director, officer or employee) in accordance with the provisions set forth in this Article V.

failure of any member of the Ligand Group or any other Person to pay, perform or otherwise discharge any Ligand Retained Liability in accordance with its respective terms, whether arising prior to, at or after the Distribution Time, (b) any Ligand Retained Asset or Ligand Retained Business, whether arising prior to, at or after the Distribution Time, or (c) any breach by Ligand of any provision of this Agreement or any Ancillary Agreement unless such Ancillary Agreement expressly provides for separate indemnification therein, in which case any such indemnification claims shall be made thereunder.

From and following the Closing, APAC shall and shall cause its Subsidiaries to indemnify, defend and hold harmless the Ligand Indemnitees from and against any and all Indemnifiable Losses of the Ligand Indemnitees pursuant to this Article V to the extent not paid by a member of the OmniAb Group.

Section 5.4 Procedures for Indemnification.

(a) Direct Claims. Other than with respect to Third Party Claims, which shall be governed by Section 5.4(b), each Ligand Indemnitee and OmniAb Indemnitee (each, an “Indemnitee”) shall notify in writing, with respect to any matter that such Indemnitee has determined has given or could give rise to a right of indemnification under this Agreement or any Ancillary Agreement, the Party which is or may be required pursuant to this Article V or pursuant to any Ancillary Agreement to make such indemnification (the “Indemnifying Party”), within forty-five (45) days of such determination, stating in such written notice the amount of the Indemnifiable Loss claimed, if known, and, to the extent practicable, method of computation thereof, and referring to the provisions of this Agreement in respect of which such right of indemnification is claimed by such Indemnitee or arises; provided, however, that the failure to provide such written notice shall not release the Indemnifying Party from any of its obligations except and solely to the extent the Indemnifying Party shall have been actually materially prejudiced as a result of such failure. The Indemnifying Party will have a period of forty-five (45) days after receipt of a notice under this Section 5.4(a) within which to respond thereto. If the Indemnifying Party fails to respond within such period, the Liability specified in such notice from the Indemnitee shall be conclusively determined to be a Liability of the Indemnifying Party hereunder. If such Indemnifying Party responds within such period and rejects such claim in whole or in part, the disputed matter shall be resolved in accordance with Article VII.

(b) Third Party Claims. If a claim or demand is made against an Indemnitee by any Person who is not a member of the Ligand Group or the OmniAb Group or APAC or their respective Affiliates (a “Third Party Claim”) as to which such Indemnitee is or may be entitled to indemnification pursuant to this Agreement or any Ancillary Agreement, such Indemnitee shall notify the Indemnifying Party in writing (which notice obligation may be satisfied by providing copies of all notices and documents received by the Indemnitee relating to the Third Party Claim), and in reasonable detail, of the Third Party Claim promptly (and in any event within the earlier of (x) forty-five (45) days or (y) two (2) Business Days prior to the final date of the applicable response period under such Third Party Claim) after receipt by such Indemnitee of written notice of the Third Party Claim; provided, however, that the failure to provide notice of any such Third Party Claim pursuant to this or the preceding sentence shall not release the Indemnifying Party from any of its obligations except and solely to the extent the Indemnifying Party shall have been actually materially prejudiced as a result of such failure. Thereafter, the Indemnitee shall deliver to the Indemnifying Party, promptly (and in any event within ten (10) Business Days) after the Indemnitee’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnitee relating to the Third Party Claim. For all purposes of this Section 5.4(b), each Party shall be deemed to have notice of the matters set forth on Schedule 1.1(97)(vii).

(c) Other than in the case of (i) Taxes addressed in the Tax Matters Agreement or Employee Matters Agreement, which shall be addressed as set forth therein or (ii) indemnification by a beneficiary Party of a guarantor Party pursuant to Section 2.10(c) (the defense of which shall be controlled by the beneficiary Party), the Indemnifying Party shall be entitled, if it so chooses, to assume the defense thereof, and if it does not assume the defense of such Third Party Claim, to participate in the defense of any Third Party Claim in accordance with the terms of Section 5.5 at such Indemnifying Party’s own cost and expense and by such Indemnifying Party’s own counsel, that is reasonably acceptable to the Indemnitee, within thirty (30) days of the receipt of an indemnification notice from such Indemnitee; provided, however, that the Indemnifying Party shall not be entitled to assume the defense of any Third Party Claim to the extent such Third Party Claim (x) is an Action by a Governmental Entity, (y) involves an allegation of a criminal violation or (z) seeks injunctive relief against the Indemnitee. In connection with the Indemnifying Party’s defense of a Third Party Claim, such Indemnitee shall have the right to employ separate counsel and to participate in (but not control) the defense, compromise, or settlement thereof, at its own expense and, in any event, shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party, at the Indemnifying Party’s expense, all witnesses, pertinent Information, materials and information in such Indemnitee’s possession or under such Indemnitee’s control relating thereto as are reasonably required by the Indemnifying Party; provided, however, that in the event of a conflict of interest between the Indemnifying Party and the applicable Indemnitee(s), or in the event that any Third Party Claim seeks equitable relief which would restrict or limit the future conduct of the Indemnitee’s business or operations, such Indemnitee(s) shall be entitled to retain, at the Indemnifying Party’s expense, separate counsel as required by the applicable rules of professional conduct with respect to such matter; provided further, that if the Indemnifying Party has assumed the defense of the Third Party Claim but has specified, and continues to assert, any reservations or exceptions to such defense or to its liability therefor, then, in any such case, the reasonable fees and expenses of one separate counsel for all Indemnitees shall be borne by the Indemnifying Party. The Indemnifying Party shall have the right to compromise or settle a Third

Party Claim the defense of which it shall have assumed pursuant to this Section 5.4(c) and any such settlement or compromise made or caused to be made of a Third Party Claim in accordance with this Article V shall be binding on the Indemnitee, in the same manner as if a final judgment or decree had been entered by a court of competent jurisdiction in the amount of such settlement or compromise. Notwithstanding the foregoing sentence, the Indemnifying Party shall not settle any such Third Party Claim without the written consent of the Indemnitee unless such settlement (A) completely and unconditionally releases the Indemnitee in connection with such matter, (B) provides relief consisting solely of money damages borne by the Indemnifying Party and (C) does not involve any admission by the Indemnitee of any wrongdoing or violation of Law.

(d) If an Indemnifying Party fails for any reason to assume responsibility for defending a Third Party Claim within the period specified in this Section 5.4, such Indemnitee may defend such Third Party Claim at the cost and expense of the Indemnifying Party. If an Indemnifying Party has failed to assume the defense of the Third Party Claim within the time period specified in clause (c) above, it shall not be a defense to any obligation to pay any amount in respect of such Third Party Claim that the Indemnifying Party was not consulted in the defense thereof, that such Indemnifying Party’s views or opinions as to the conduct of such defense were not accepted or adopted, that such Indemnifying Party does not approve of the quality or manner of the defense thereof or that such Third Party Claim was incurred by reason of a settlement rather than by a judgment or other determination of liability.

(e) Except as otherwise set forth in Section 6.6 and Section 7.3, or to the extent set forth in any Ancillary Agreement, absent fraud or willful misconduct by an Indemnifying Party, the indemnification provisions of this Article V shall be the sole and exclusive remedy of an Indemnitee for any monetary or compensatory damages or losses resulting from any breach of this Agreement or any Ancillary Agreement and each Indemnitee expressly waives and relinquishes any and all rights, claims or remedies such Person may have with respect to the foregoing other than under this Article V against any Indemnifying Party. For the avoidance of doubt, all disputes in respect of this Article V shall be resolved in accordance with Article VII.

(f) Notwithstanding the foregoing, to the extent any Ancillary Agreement provides procedures for indemnification that differ from the provisions set forth in this Section 5.4, the terms of the Ancillary Agreement will govern.

(g) The provisions of this Article V shall apply to Third Party Claims that are already pending or asserted as well as Third Party Claims brought or asserted after the date of this Agreement. There shall be no requirement under this Section 5.4 to give a notice with respect to any Third Party Claim that exists as of the Distribution Time. The Parties acknowledge that Liabilities for Actions (regardless of the parties to the Actions) may be partly Ligand Liabilities and partly OmniAb Liabilities. If the Parties cannot agree on the allocation of any such Liabilities for Actions, they shall resolve the matter pursuant to the procedures set forth in Article VII. Neither Party shall, nor shall either Party permit its Subsidiaries to, file Third Party claims or cross-claims against the other Party or its Subsidiaries in an Action in which a Third Party Claim is being resolved.

Section 5.5 Cooperation in Defense and Settlement.

(a) With respect to any Third Party Claim that implicates both the OmniAb Group (or APAC and its Subsidiaries, as applicable) and the Ligand Group in any material respect due to the allocation of Liabilities, responsibilities for management of defense and related indemnities pursuant to this Agreement or any of the Ancillary Agreements, OmniAb (or APAC, as applicable) and Ligand agree to use commercially reasonable efforts to cooperate fully and maintain a joint defense (in a manner that, to the extent reasonably practicable, will preserve for all Parties any Privilege with respect thereto). The Party that is not responsible for managing the defense of any such Third Party Claim shall, upon reasonable request, be consulted with respect to significant matters relating thereto and may, if necessary or helpful, retain counsel to assist in the defense of such claims. Notwithstanding the foregoing, nothing in this Section 5.5(a) shall derogate from any Party’s rights to control the defense of any Action in accordance with Section 5.4.

(b) Notwithstanding anything to the contrary in this Agreement, with respect to any Action (i) by a Governmental Entity against OmniAb relating to matters involving anti-bribery, anti-corruption, anti-money laundering, export control and similar laws, where the facts and circumstances giving rise to the Action occurred prior to the Distribution Time and (ii) where the resolution of such Action by order, judgment, settlement or otherwise, would reasonably be expected to include any condition, limitation or other stipulation that adversely impacts the conduct of the Ligand Retained Businesses, Ligand shall have, at Ligand’s expense, the reasonable opportunity to consult, advise and comment on preparation regarding any such Action, including with regard to any drafts of notices and other conferences and communications to be provided or submitted by OmniAb to any third party involved in such Action (including any Governmental Entity), to the extent that Ligand’s participation does not affect the defense of any such Action or any privilege in an adverse manner; provided that to the extent that any such action requires the submission by OmniAb of any content relating to any current or former officer or director of Ligand, such content will only be submitted in a form approved by Ligand in its reasonable discretion.

(c) Notwithstanding anything to the contrary in this Agreement, with respect to any notices or reports to be submitted to, or reporting, disclosure, filing or other requirements to be made with, any Governmental Entity by OmniAb or its Subsidiaries (“Governmental Filing”) where the Governmental Filing requires disclosure of facts, information or data that relate, in whole or in part, to periods prior to the Distribution Time, Ligand shall have the reasonable opportunity to consult, advise and comment on the preparation and content of any such Governmental Filing in advance of its submission to a Governmental Entity, and OmniAb shall in good faith consider and take into account any comments so provided by Ligand with respect to such Governmental Filing.

(d) Each of Ligand and OmniAb agrees that at all times from and after the Distribution Time, if an Action is commenced by a third party naming two (2) or more Parties (or any member of such Parties’ respective Groups) as defendants and with respect to which one or more named Parties (or any member of such Party’s respective Group) is a nominal defendant and/or such Action is otherwise not a Liability allocated to such named Party under this Agreement or any Ancillary Agreement, then the other Party or Parties shall use commercially reasonable efforts at its own expense to cause such nominal defendant to be removed from such Action, as soon as reasonably practicable.

Section 5.6 Indemnification Payments. Indemnification required by this Article V shall be made by periodic payments of the amount of Indemnifiable Losses in a timely fashion during the course of the investigation or defense, as and when bills are received or an Indemnifiable Loss incurred.

Section 5.7 Indemnification Obligations Net of Insurance Proceeds and Other Amounts.

(a) Any recovery by any Indemnitee for any Indemnifiable Loss subject to indemnification pursuant to this Article V shall be calculated (i) net of Insurance Proceeds actually received by such Indemnitee with respect to any Indemnifiable Loss (which such proceeds shall be reduced by the present value, based on that Party’s then cost of short-term borrowing, of future premium increases known at such time) and (ii) net of any proceeds actually received by the Indemnitee from any unaffiliated third party with respect to any such Liability corresponding to the Indemnifiable Loss (“Third Party Proceeds”). Accordingly, the amount which any Indemnifying Party is required to pay pursuant to this Article V to any Indemnitee pursuant to this Article V shall be reduced by any Insurance Proceeds or Third Party Proceeds theretofore actually recovered by or on behalf of the Indemnitee corresponding to the related Indemnifiable Loss. If an Indemnitee receives a payment required by this Agreement from an Indemnifying Party corresponding to any Indemnifiable Loss (an “Indemnity Payment”) and subsequently receives Insurance Proceeds or Third Party Proceeds, then the Indemnitee shall pay to the Indemnifying Party an amount equal to the excess of the Indemnity Payment received over the amount of the Indemnity Payment that would have been due if the Insurance Proceeds or Third Party Proceeds had been received, realized or recovered before the Indemnity Payment was made.

(b) Any Indemnity Payment shall be increased as necessary so that after making all payments corresponding to Taxes imposed on or attributable to such Indemnity Payment, the Indemnitee receives an amount equal to the sum it would have received had no such Taxes been imposed.

(c) The Parties hereby agree that an insurer or other third party that would otherwise be obligated to pay any amount shall not be relieved of the responsibility with respect thereto or have any subrogation rights with respect thereto by virtue of any provision contained in this Agreement or any Ancillary Agreement, and that no insurer or any other third party shall be entitled to a “windfall” (e.g., a benefit they would not otherwise be entitled to receive, or the reduction or elimination of an insurance coverage obligation that they would otherwise have, in the absence of the indemnification or release provisions) by virtue of any provision contained in this Agreement or any Ancillary Agreement. Each Party shall, and shall cause its Subsidiaries to, use commercially reasonable efforts to collect or recover, or allow the Indemnifying Party to collect or recover, or cooperate with each other in collecting or recovering, any Insurance Proceeds that may be collectible or recoverable respecting the Liabilities for which indemnification may be available under this Article V. Notwithstanding the foregoing, an Indemnifying Party may not delay making any indemnification payment required under the terms of this Agreement, or otherwise satisfying any indemnification obligation, pending the outcome of any Actions to collect or recover Insurance Proceeds, and an Indemnitee need not attempt to collect any Insurance Proceeds prior to making a claim for indemnification or receiving any Indemnity Payment otherwise owed to it under this Agreement or any Ancillary Agreement.

Section 5.8 Contribution. If the indemnification provided for in this Article V is unavailable for any reason to an Indemnitee (other than failure to provide notice with respect to any Third Party Claims in accordance with Section 5.4(b)) in respect of any Indemnifiable Loss, then the Indemnifying Party shall, in accordance with this Section 5.8, contribute to the Indemnifiable Losses incurred, paid or payable by such Indemnitee as a result of such Indemnifiable Loss in such proportion as is appropriate to reflect the relative fault of OmniAb and each other member of the OmniAb Group, on the one hand, and Ligand and each other member of the Ligand Group, on the other hand, in connection with the circumstances which resulted in such Indemnifiable Loss. With respect to any Indemnifiable Losses arising out of or related to information contained in the Spin-off Disclosure Documents or other securities law filing, the relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact relates to information regarding the OmniAb Business supplied by a member of the OmniAb Group, on the one hand, or regarding the Ligand Retained Business supplied by a member of the Ligand Group, on the other hand.

Section 5.9 Additional Matters; Survival of Indemnities.

(a) The indemnity agreements contained in this Article V shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Indemnitee; and (ii) the knowledge by the Indemnitee of Indemnifiable Losses for which it might be entitled to indemnification hereunder. The indemnity agreements contained in this Article V shall survive the Distribution.

(b) The rights and obligations of any member of the Ligand Group, any member of the OmniAb Group or APAC, in each case, under this Article V shall survive (i) the sale or other Transfer by any Party or its Affiliates of any Assets or businesses or the assignment by it of any Liabilities and (ii) any merger, consolidation, business combination, restructuring, recapitalization, reorganization or similar transaction involving either Party or any of its Subsidiaries.

ARTICLE VI

CONFIDENTIALITY; PRIVILEGE

Section 6.1 Preservation of Corporate Records. Except as otherwise required or agreed in writing, or as otherwise provided in any Ancillary Agreement, with regard to any Information referenced in Section 6.2, each Party shall use its commercially reasonable efforts, at such Party’s sole cost and expense, to retain, until the latest of, as applicable, (i) the date on which such Information is no longer required to be retained pursuant to the applicable record retention policy of Ligand or such other member of the Ligand Group, respectively, as in effect immediately prior to the Distribution Time, including, without limitation, pursuant to any “Litigation Hold” issued by Ligand or any of its Subsidiaries prior to the Distribution Time, (ii) the concluding date of any period as may be required by any applicable Law, (iii) the concluding

date of any period during which such Information relates to a pending or threatened Action which is known to the members of the Ligand Group or the OmniAb Group, as applicable, in possession of such Information at the time any retention obligation with regard to such Information would otherwise expire, and (iv) the concluding date of any period during which the destruction of such Information could interfere with a pending or threatened investigation by a Governmental Entity which is known to the members of the Ligand Group or the OmniAb Group, as applicable, in possession of such Information at the time any retention obligation with regard to such Information would otherwise expire; provided that with respect to any pending or threatened Action arising after the Distribution Time, clause (iii) of this sentence applies only to the extent that whichever member of the Ligand Group or the OmniAb Group, as applicable, is in possession of such Information has been notified in writing pursuant to a “Litigation Hold” by the other Party of the relevant pending or threatened Action. The Parties agree that upon written request from the other that certain Information relating to the OmniAb Business, the Ligand Retained Businesses or the transactions contemplated hereby be retained in connection with an Action, the Parties shall use reasonable efforts to preserve and not to destroy or dispose of such Information without the consent of the requesting Party.

Section 6.2 Access to Information. Other than in circumstances in which indemnification is sought pursuant to Article V (in which event the provisions of such Article V shall govern) or for matters related to provision of Tax records (in which event the provisions of the Tax Matters Agreement and Employee Matters Agreement shall govern) and subject to appropriate restrictions for Privileged Information or Confidential Information:

(a) After the Distribution Time, and subject to compliance with the terms of the Ancillary Agreements, upon the prior written reasonable request by, and at the expense of, OmniAb for specific and identified Information:

(i) that (x) relates to OmniAb or the OmniAb Business, as the case may be, prior to the Distribution Time or (y) is necessary for OmniAb to comply with the terms of, or otherwise perform under, any Ancillary Agreement to which Ligand and/or OmniAb are parties, Ligand shall provide, as soon as reasonably practicable following the receipt of such request, appropriate copies of such Information (or the originals thereof if OmniAb has a reasonable need for such originals) in the possession or control of Ligand or any of its Affiliates or Subsidiaries, but only to the extent such items so relate and are not already in the possession or control of OmniAb; provided that, to the extent any originals are delivered to OmniAb pursuant to this Agreement or the Ancillary Agreements, OmniAb shall, at its own expense, return them to Ligand within a reasonable time after the need to retain such originals has ceased; provided further that, such obligation to provide any requested Information shall terminate and be of no further force and effect on the date that is the first anniversary of the date of this Agreement; provided further that, in the event that Ligand, in its sole discretion, determines that any such access or the provision of any such Information (including information requested under Section 6.3) would violate any Law or Contract with a third party or could reasonably result in the waiver of any Privilege, Ligand shall not be obligated to provide such Information requested by OmniAb;

Each Party will reasonably cooperate with, and permit and make any necessary employees available to, the other Party, in connection with the other Party’s preparation of any Amended Financial Reports.

Section 6.4 Witness Services. At all times from and after the Distribution Time, each of Ligand and OmniAb shall use its commercially reasonable efforts to make available to the other, upon reasonable written request, its and its Subsidiaries’ officers, directors, employees and agents (taking into account the business demands of such individuals) as witnesses to the extent that (i) such Persons may reasonably be required to testify in connection with the prosecution or defense of any Action in which the requesting Party may from time to time be involved (except for claims, demands or Actions in which one or more members of one Group is adverse to one or more members of the other Group) and (ii) there is no conflict in the Action between the requesting Party and the other Party. A Party providing a witness to the other Party under this Section 6.4 shall be entitled to receive from the recipient of such witness services, upon the presentation of invoices therefor, payments for such amounts, relating to supplies, disbursements and other out-of-pocket expenses (which shall not include the costs of salaries and benefits of employees who are witnesses or any pro rata portion of overhead or other costs of employing such employees which would have been incurred by such employees’ employer regardless of the employees’ service as witnesses), as may be reasonably incurred and properly paid under applicable Law.

Section 6.5 Reimbursement; Other Matters. Except to the extent otherwise contemplated by this Agreement or any Ancillary Agreement, a Party providing Information or access to Information to the other Party under this Article VI shall be entitled to receive from the recipient, upon the presentation of invoices therefor, payments for such amounts, relating to supplies, disbursements and other out-of-pocket expenses (which shall not include the costs of salaries and benefits of employees of such Party or any pro rata portion of overhead or other costs of employing such employees which would have been incurred by such employees’ employer regardless of the employees’ service with respect to the foregoing), as may be reasonably incurred in providing such Information or access to such Information.

Section 6.6 Confidentiality.

(a) Notwithstanding any termination of this Agreement, and except as otherwise provided in the Ancillary Agreements, each of Ligand and OmniAb shall hold, and shall cause their respective Affiliates and their officers, employees, agents, consultants and advisors to hold, in strict confidence (and not to disclose or release or, except as otherwise permitted by this Agreement or any Ancillary Agreement, use, including for any ongoing or future commercial purpose, without the prior written consent of the Party to whom the Confidential Information relates (which may be withheld in such Party’s sole and absolute discretion, except where disclosure is required by applicable Law)), any and all Confidential Information concerning or belonging to the other Party or its Affiliates; provided that each Party may disclose, or may permit disclosure of, Confidential Information (i) to its respective auditors, attorneys, financial advisors, bankers and other appropriate consultants and advisors who have a need to know such Information for auditing and other non-commercial purposes and are informed of the obligation to hold such Information confidential and in respect of whose failure to comply with such obligations, the applicable Party will be responsible, (ii) if any Party or any of its respective Subsidiaries is required or compelled to disclose any such Confidential Information by judicial or administrative process or by other requirements of Law or stock exchange rule or is advised by outside counsel in connection with a proceeding brought by a Governmental Entity that it is advisable to do so, (iii) as required in connection with any legal or other proceeding by one Party against the other Party or in respect of claims by one Party against the other Party brought in a proceeding, (iv) as necessary in order to permit a Party to prepare and disclose its financial statements in connection with any regulatory filings or Tax Returns, (v)

as necessary for a Party to enforce its rights or perform its obligations under this Agreement (including pursuant to Section 2.3) or an Ancillary Agreement, (vi) to Governmental Entities in accordance with applicable procurement regulations and contract requirements or (vii) to other Persons in connection with their evaluation of, and negotiating and consummating, a potential strategic transaction, to the extent reasonably necessary in connection therewith, provided an appropriate and customary confidentiality agreement has been entered into with the Person receiving such Confidential Information. Notwithstanding the foregoing, in the event that any demand or request for disclosure of Confidential Information is made by a third party pursuant to clause (ii), (iii), (v) or (vi) above, each Party, as applicable, shall promptly notify (to the extent permissible by Law) the Party to whom the Confidential Information relates of the existence of such request, demand or disclosure requirement and shall provide such affected Party a reasonable opportunity to seek an appropriate protective order or other remedy, which such Party will cooperate in obtaining to the extent reasonably practicable. In the event that such appropriate protective order or other remedy is not obtained, the Party which faces the disclosure requirement shall furnish only that portion of the Confidential Information that is required to be disclosed and shall take commercially reasonable steps to ensure that confidential treatment is accorded such Confidential Information.

(b) Each Party acknowledges that it and the other members of its Group may have in its or their possession confidential or proprietary Information of third parties that was received under confidentiality or non-disclosure agreements with such third party while such Party and/or members of its Group were part of the Ligand Group. Each Party shall comply, and shall cause the other members of its Group to comply, and shall cause its and their respective officers, employees, agents, consultants and advisors (or potential buyers) to comply, with all terms and conditions of any such third-party agreements entered into prior to the Distribution Time, with respect to any confidential and proprietary Information of third parties to which it or any other member of its Group has had access.

(c) Notwithstanding anything to the contrary set forth herein, (i) the Parties shall be deemed to have satisfied their obligations hereunder with respect to Confidential Information if they exercise at least the same degree of care that applies to Ligand’s confidential and proprietary information pursuant to policies in effect as of the Distribution Time and (ii) confidentiality obligations provided for in any Contract between each Party or its Subsidiaries and their respective employees shall remain in full force and effect. Notwithstanding anything to the contrary set forth herein, Confidential Information of any Party in the possession of and used by any other Party as of the Distribution Time may continue to be used by such Party in possession of the Confidential Information in and only in the operation of the OmniAb Business (in the case of the OmniAb Group) or the Ligand Retained Business (in the case of the Ligand Group); provided that such Confidential Information may only be used by such Party and its officers, employees, agents, consultants and advisors in the specific manner and for the specific purposes for which it is used as of the date of this Agreement, and may only be shared with additional officers, employees, agents, consultants and advisors of such Party on a need-to-know basis exclusively with regard to such specified use; provided further that such Confidential Information may be used only so long as the Confidential Information is maintained in confidence and not disclosed in violation of Section 6.6(a).

(d) The Parties agree that irreparable damage may occur in the event that the provisions of this Section 6.6 were not performed in accordance with their specific terms. Accordingly, it is hereby agreed that the Parties shall be entitled to seek an injunction or injunctions to enforce specifically the terms and provisions hereof in any court having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.

(e) For the avoidance of doubt and notwithstanding any other provision of this Section 6.6, (i) the disclosure and sharing of Privileged Information shall be governed solely by Section 6.7, and (ii) Information that is subject to any confidentiality provision or other disclosure restriction in any Ancillary Agreement shall be governed by the terms of such Ancillary Agreement.

(f) For the avoidance of doubt and notwithstanding any other provision of this Section 6.6, following the Distribution Time, the confidentiality obligations under this Agreement shall continue to apply to any and all Confidential Information concerning or belonging to each Party or its Affiliates that is shared or disclosed with the other Party or its Affiliates, whether or not such Confidential Information is shared pursuant to this Agreement, any Ancillary Agreement or otherwise.

Section 6.7 Privilege Matters.

(a) Pre-Distribution Services. The Parties recognize that legal and other professional services that have been and will be provided prior to the Distribution Time have been and will be rendered for the collective benefit of each of the members of the Ligand Group and the OmniAb Group, and that each of the members of the Ligand Group and the OmniAb Group should be deemed to be the client with respect to such pre-Distribution services for the purposes of asserting all privileges, immunities, or other protections from disclosure which may be asserted under applicable Law, including, but not limited to, the attorney-client privilege, business strategy privilege, joint defense privilege, common interest privilege, and protection under the work-product doctrine (“Privilege”). The Parties shall have a shared Privilege with respect to all Information subject to Privilege (“Privileged Information”) which relates to such pre-Distribution services. For the avoidance of doubt, Privileged Information within the scope of this Section 6.7 includes, but is not limited to, services rendered by legal counsel retained or employed by any Party (or any member of such Party’s respective Group), including outside counsel and in-house counsel.

(b) Post-Distribution Services. The Parties recognize that legal and other professional services will be provided following the Distribution Time to each of Ligand and OmniAb. The Parties further recognize that certain of such post-Distribution services will be rendered solely for the benefit of Ligand or OmniAb, as the case may be, while other such post-Distribution services may be rendered with respect to claims, proceedings, litigation, disputes, or other matters which involve both Ligand and OmniAb. With respect to such post-Distribution services and related Privileged Information, the Parties agree as follows:

(i) All Privileged Information relating to any claims, proceedings, litigation, disputes or other matters which involve both Ligand and OmniAb shall be subject to a shared Privilege among the Parties involved in the claims, proceedings, litigation, disputes, or other matters at issue; and

(ii) Except as otherwise provided in Section 6.7(c)(i), Privileged Information relating to post-Distribution services provided solely to one of Ligand or OmniAb shall not be deemed shared between the Parties, provided, that the foregoing shall not be construed or interpreted to restrict the right or authority of the Parties (x) to enter into any further agreement, not otherwise inconsistent with the terms of this Agreement, concerning the sharing of Privileged Information or (y) otherwise to share Privileged Information without waiving any Privilege which could be asserted under applicable Law.

(c) The Parties agree as follows regarding all Privileged Information with respect to which the Parties shall have a shared Privilege under Section 6.7(a) or (b):

(i) Subject to Section 6.7(c)(iii), neither Party may waive, allege or purport to waive, any Privilege which could be asserted under any applicable Law, and in which the other Party has a shared Privilege, without the written consent of the other Party, which shall not be unreasonably withheld or delayed;

(ii) If a dispute arises between or among the Parties or their respective Subsidiaries regarding whether a Privilege should be waived to protect or advance the interest of any Party, each Party agrees that it shall negotiate in good faith, and shall endeavor to minimize any prejudice to the rights of the other Party. Neither party shall unreasonably withhold consent to any request for waiver by the other Party, and each Party specifically agrees that it shall not withhold consent to waive for any purpose except to protect its own legitimate interests; and

(iii) In the event of any litigation or dispute between the Parties, or any members of their respective Groups, either such Party may waive a Privilege in which the other Party or member of such Group has a shared Privilege, without obtaining the consent of the other Party; provided that such waiver of a shared Privilege shall be effective only as to the use of Privileged Information with respect to the litigation or dispute between the Parties and/or the applicable members of their respective Groups, and shall not operate as a waiver of the shared Privilege with respect to third parties.

(d) The transfer of all Information pursuant to this Agreement is made in reliance on the agreement of Ligand and OmniAb as set forth in Section 6.6 and this Section 6.7, to maintain the confidentiality of Privileged Information and to assert and maintain any applicable Privilege. The access to Information being granted pursuant to Section 5.5, Section 6.1, Section 6.2 and Section 6.3 , the agreement to provide witnesses and individuals pursuant to Section 5.5 and Section 6.4, the furnishing of notices and documents and other cooperative efforts contemplated by Section 5.5, and the transfer of Privileged Information between the Parties and their respective Subsidiaries pursuant to this Agreement shall not be deemed a waiver of any Privilege that has been or may be asserted under this Agreement or otherwise.

Section 6.8 Ownership of Information. Any Information owned by one Party or any of its Subsidiaries that is provided to a requesting Party pursuant to this Article VI shall be deemed to remain the property of the providing Party. Unless expressly set forth herein, or unless expressly agreed in a subsequent and separate agreement, nothing contained in this Agreement shall be construed as granting a license or other rights to any Party with respect to any such Information, whether by implication, estoppel or otherwise.

Section 6.9 Processing of Personal Information.

(a) Both Parties shall cooperate to ensure that their respective Processing of Personal Information hereunder does and will materially comply with all applicable Privacy Requirements and take all reasonable precautions to avoid acts that place the other Party in breach of its obligations under any applicable Privacy Requirements. Nothing in this Section 6.9 shall be deemed to prevent any Party from taking the steps it reasonably deems necessary to comply with any applicable Privacy Laws.

(b) To the extent required to do so by applicable Privacy Requirements as a result of or in connection with the transactions contemplated hereby, including the completion of the Internal Reorganization, the Parties agree to enter into such data processing agreements as required to comply with applicable Privacy Laws and shall act reasonably and in good faith in doing so.

(c) It is understood and agreed by the Parties that the transfer of Personal Information in connection with the Transfer of Assets will not violate any Privacy Requirements in any material respect.

Section 6.10 Other Agreements. The rights and obligations granted under this Article VI are subject to any specific limitations, qualifications or additional provisions on the sharing, exchange or confidential treatment of Information set forth in any Ancillary Agreement.

ARTICLE VIII

INSURANCE

Section 8.1 Insurance Matters. The provisions of this Section 8.1 shall apply only to the extent not otherwise provided for in the Employee Matters Agreement.

(a) The Parties intend by this Agreement that, to the extent permitted under the terms of any applicable insurance policy, OmniAb, each other member of the OmniAb Group and each of their respective directors, officers and employees will be successors in interest and/or additional insureds and will have and be fully entitled to continue to exercise all rights that any of them may have as of the Distribution Time (with respect to events occurring or claimed to have occurred before the Distribution Time) as a Subsidiary, Affiliate, division, director, officer or employee of Ligand before the Distribution Time under any insurance policy, including any rights that OmniAb, any other member of the OmniAb Group or any of its or their respective directors, officers, or employees may have as an insured or additional named insured, Subsidiary, Affiliate, division, director, officer or employee to avail itself, himself or herself of any policy of insurance or any agreements related to the policies in effect before the Distribution Time, with respect to events occurring before the Distribution Time.

(b) After the Distribution Time, Ligand (and each other member of the Ligand Group) and OmniAb (and each other member of the OmniAb Group) shall not, without the consent of OmniAb or Ligand, respectively (such consent not to be unreasonably withheld, conditioned or delayed), provide any insurance carrier with a release or amend, modify or waive any rights under any insurance policy if such release, amendment, modification or waiver thereunder would materially adversely affect any rights of any member of the Group of the other Party with respect to insurance coverage otherwise afforded to such other Party for pre-Distribution claims; provided, however, that the foregoing shall not (i) preclude any member of any Group from presenting any claim or from exhausting any policy limit, (ii) require any member of any Group to pay any premium or other amount or to incur any Liability or (iii) require any member of any Group to renew, extend or continue any policy in force.

(d) No member of the Ligand Group or any Ligand Indemnitee will have any Liabilities whatsoever as a result of the insurance policies as in effect at any time before the Distribution Time, including as a result of (i) the level or scope of any insurance, (ii) the creditworthiness of any insurance carrier, (iii) the terms and conditions of any policy, or (iv) the adequacy or timeliness of any notice to any insurance carrier with respect to any claim or potential claim.

(e) Except to the extent otherwise provided in Section 8.1(b), in no event will Ligand, any other member of the Ligand Group or any Ligand Indemnitee have any Liability or obligation whatsoever to any member of the OmniAb Group if any insurance policy is terminated or otherwise ceases to be in effect for any reason, is unavailable or inadequate to cover any Liability of any member of the OmniAb Group for any reason whatsoever or is not renewed or extended beyond the current expiration date of any such insurance policy.

(f) This Agreement shall not be considered as an attempted assignment of any policy of insurance or as a contract of insurance and shall not be construed to waive any right or remedy of any members of the Ligand Group in respect of any insurance policy or any other contract or policy of insurance.

(g) Nothing in this Agreement will be deemed to restrict any member of the OmniAb Group from acquiring at its own expense any other insurance policy in respect of any Liabilities or covering any period. After the Distribution Time, OmniAb will acquire its own insurance policies covering the OmniAb Group and each of their respective directors, officers and employees.

(h) To the extent that any insurance policy provides for the reinstatement of policy limits, and both Ligand and OmniAb desire to reinstate such limits, the cost of reinstatement will be shared by Ligand and OmniAb as the Parties may agree. If either Party, in its sole discretion, determines that such reinstatement would not be beneficial, that Party shall not contribute to the cost of reinstatement and will not make any claim thereunder nor otherwise seek to benefit from the reinstated policy limits.

(i) For purposes of this Agreement, “Covered Matter” shall mean any matter, whether arising before or after the Distribution Time, with respect to which any OmniAb Indemnitee may seek to exercise any right under any insurance policy pursuant to this Section 8.1. If OmniAb receives notice or otherwise learns of any Covered Matter, OmniAb shall promptly give Ligand written notice thereof. Any such notice shall describe the Covered Matter in reasonable detail. With respect to each Covered Matter and any Joint Claim, OmniAb shall have sole responsibility for reporting the claim to the insurance carrier and will provide a copy of such report to OmniAb. If Ligand or another member of the Ligand Group fails to notify OmniAb within fifteen (15) days that it has submitted an insurance claim with respect to a Covered Matter or Joint Claim, OmniAb shall be permitted to submit (on behalf of the applicable OmniAb Indemnitee) such insurance claim.

(j) Each of OmniAb and Ligand will share such information as is reasonably necessary in order to permit the other Party to manage and conduct its insurance matters in an orderly fashion and provide the other Party with any assistance that is reasonably necessary or beneficial in connection with such Party’s insurance matters.

ARTICLE IX

EACH OF LIGAND, OMNIAB AND APAC CERTIFIES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, INSTRUMENT OR DOCUMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS SET FORTH ABOVE IN THIS SECTION 9.16(c).

The Parties and APAC agree that, from and after the Distribution Time, the remedies at law for any breach or threatened breach of this Agreement or any Ancillary Agreement, including monetary damages, are inadequate compensation for any Indemnifiable Loss, that any defense in any action for specific performance that a remedy at law would be adequate is hereby waived, and that any requirements for the securing or posting of any bond with such remedy are hereby waived.

Section 9.18 Severability. In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby. The Parties and APAC shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions, the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

Section 9.19 Interpretation. The Parties and APAC have participated jointly in the negotiation and drafting of this Agreement. This Agreement shall be construed without regard to any presumption or rule requiring construction or interpretation against the Party or APAC, as the case may be, drafting or causing any instrument to be drafted.

Section 9.20 No Duplication; No Double Recovery. Nothing in this Agreement is intended to confer to or impose upon any Party or APAC a duplicative right, entitlement, obligation or recovery with respect to any matter arising out of the same facts and circumstances (including with respect to the rights, entitlements, obligations and recoveries that may arise out of one or more of the following Sections: Section 5.2; Section 5.3; and Section 5.4).

Section 9.21 Tax Treatment of Payments. Unless otherwise required by a Final Determination, this Agreement or the Tax Matters Agreement or otherwise agreed to among the Parties and APAC, for U.S. federal Tax purposes, any payment made pursuant to this Agreement (other than any payment of interest pursuant to Section 9.11) by: (i) OmniAb to Ligand shall be treated for all Tax purposes as a distribution by OmniAb to Ligand with respect to stock of OmniAb occurring on or immediately before the Distribution Time; or (ii) Ligand to OmniAb shall be treated for all Tax purposes as a tax-free contribution by Ligand to OmniAb with respect to its stock occurring on or immediately before the Distribution Time; and in each case, no Party or APAC shall take any position inconsistent with such treatment. In the event that a Taxing Authority asserts that a Party’s treatment of a payment pursuant to this Agreement should be other than as set forth in the preceding sentence, such Party shall use its commercially reasonable efforts to contest such challenge.

Section 9.22 No Waiver. No failure to exercise and no delay in exercising, on the part of any Party, any right, remedy, power or privilege hereunder or under the other Ancillary Agreements shall operate as a waiver hereof or thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder or thereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

Section 9.23 No Admission of Liability. The allocation of Assets and Liabilities herein (including on the Schedules hereto) is solely for the purpose of allocating such Assets and Liabilities between Ligand and OmniAb and is not intended as an admission of liability or responsibility for any alleged Liabilities vis-à-vis any third party, including with respect to the Liabilities of any non-wholly owned Subsidiary of Ligand or OmniAb.

(f) Each of Remainco, on behalf of itself and all other members of the Remainco Group, Spinco, on behalf of itself and all other members of the Spinco Group, and Parent represents and warrants that it has no plan or intent to take any action which is inconsistent with any statements or representations made in the Tax Materials.

Section 13.2 Restrictions Relating to the Distribution.

(a) Remainco, on behalf of itself and all other members of the Remainco Group, hereby covenants and agrees that no member of the Remainco Group will take, fail to take, or to permit to be taken: (i) any action where such action or failure to act would be inconsistent with or cause to be untrue any statement, information, covenant or representation in the Tax Materials, (ii) any action where such action or failure to act would adversely affect, or could reasonably be expected to adversely affect, the Tax-Free Status of the Transactions or (iii) any action which constitutes a Remainco Disqualifying Action.

(b) Each of Spinco and Parent, on behalf of itself and all other members of their respective Groups, hereby covenants and agrees that no member of their Group will take, fail to take, or permit to be taken: (i) any action where such action or failure to act would be inconsistent with or cause to be untrue any statement, information, covenant or representation in the Tax Materials, (ii) any action where such action or failure to act would reasonably be expected to adversely affect the Tax-Free Status of the Transactions or (iii) any action which constitutes a Spinco Disqualifying Action.

(i) shall continue and cause to be continued the active conduct of the Spinco Business for purposes of Section 355(b)(2) of the Code, taking into account Section 355(b)(3) of the Code, as conducted immediately prior to the Distribution,

(ii) shall not voluntarily dissolve or liquidate themselves or any member of the Spinco Group (including any action that is a liquidation for U.S. federal income tax purposes),

(iii) shall not (1) enter into any Proposed Acquisition Transaction or, to the extent Spinco or Parent has the right to prohibit any Proposed Acquisition Transaction, permit any Proposed Acquisition Transaction to occur (whether by (A) redeeming rights under a shareholder rights plan, (B) finding a tender offer to be a “permitted offer” under any such plan or otherwise causing any such plan to be inapplicable or neutralized with respect to any Proposed Acquisition Transaction, (C) approving any Proposed Acquisition Transaction, whether for purposes of Section 203 of the General Corporation Law of the State of Delaware or any similar corporate statute, any “fair price” or other provision of the charter or bylaws of Parent or Spinco, (D) amending its certificate of incorporation to declassify its board of directors or approving any such amendment, or (E) otherwise), (2) redeem or otherwise repurchase (directly or through an Affiliate) any stock, or rights to acquire stock except (A) to the extent such repurchases satisfy Section 4.05(1)(b) of Revenue Procedure 96-30 (as in effect prior to the amendment of such Revenue Procedure by Revenue Procedure 2003-48), (B) to the extent reasonably necessary to pay the total tax liability arising from the vesting of an Equity Award, or (C) through a net exercise of an Equity Award, (3) amend its certificate of incorporation (or other organizational documents), or take any other action, whether through a stockholder vote or otherwise, affecting the relative voting rights of its capital stock (including through the conversion of any capital stock into another class of capital stock), (4) merge or consolidate, or agree to merge or consolidate, Parent or Spinco with any other Person (other than pursuant to the Merger) unless, in the case of a merger or consolidation, Parent or Spinco (as applicable) is the survivor of such merger or consolidation or (5) take any other action or actions (including any action or transaction that would be reasonably likely to be inconsistent with any representation made in the Tax Materials) which in the aggregate (and taking into account the Merger) would, when combined with any other direct or indirect changes in ownership of Parent or Spinco capital stock pertinent for purposes of Section 355(e) of the Code, have the effect of causing or permitting one or more Persons (whether or not acting in concert) to acquire directly or indirectly stock representing a fifty percent (50%) or greater interest in Parent or Spinco or would reasonably be expected to result in a failure to preserve the Tax-Free Status of the Transactions; and

(iv) shall not and shall not permit any member of the Spinco Group, to sell, transfer, or otherwise dispose of or agree to, sell, transfer or otherwise dispose (including in any transaction treated for U.S. federal income tax purposes as a sale, transfer or disposition) of assets (including, any shares of capital stock of a Subsidiary) that, in the aggregate, constitute more than thirty percent (30%) of the consolidated gross assets of Spinco or the Spinco Group; provided, that this clause (iv) shall not apply to (1) sales, transfers, or dispositions of assets in the ordinary course of business, (2) any cash paid to acquire assets from an unrelated Person in an arm’s-length transaction, (3) any assets transferred to a Person that is disregarded as an entity separate from the transferor for U.S. federal income tax purposes or (4) any mandatory or optional repayment (or pre-payment) of any indebtedness of Spinco or any member of the Spinco Group; provided, further that the percentages of gross assets or consolidated gross assets of Spinco or the Spinco Group, as the case may be, sold, transferred, or otherwise disposed of, shall be based on the fair market value of the gross assets of Spinco and the members of the Spinco Group as of the Distribution Date. For purposes of this Section 4.2(c)(iv), a merger of Spinco or one of its Subsidiaries with and into any Person that is not a wholly owned Subsidiary of Spinco shall constitute a disposition of all of the assets of Spinco or such Subsidiary.

(d) Notwithstanding the restrictions imposed by Sections 4.2(b) and 4.2(c), Parent, Spinco or a member of the Spinco Group may take any of the actions or transactions described therein if Spinco either (i) obtains an Unqualified Tax Opinion in form and substance reasonably satisfactory to Remainco, (ii) obtains a ruling from the IRS to the effect that such actions or transactions will not affect the Tax-Free Status of the Transactions (a “Post-Distribution Ruling”) or (iii) obtains the prior written consent of Remainco waiving the requirement that Spinco obtain an Unqualified Tax Opinion or Post-Distribution Ruling, such waiver to be provided in Remainco’s sole and absolute discretion. Remainco shall cooperate in good faith with any reasonable requests of Spinco in connection with securing any Post-Distribution Ruling or Unqualified Tax Opinion. Remainco’s evaluation of an Unqualified Tax Opinion may consider, among other factors, the appropriateness of any underlying assumptions, representations, and covenants made in connection with such opinion. Spinco shall bear all costs and expenses of securing any such Unqualified Tax Opinion or Post-Distribution Ruling and shall reimburse Remainco for all reasonable out-of-pocket expenses that Remainco or any of its Affiliates may incur in good faith in connection with obtaining or evaluating any such Unqualified Tax Opinion or Post-Distribution Ruling. Except as otherwise provided in Section 5.1(d), neither the delivery of an Unqualified Tax Opinion, receipt of a Post-Distribution Ruling nor Remainco’s waiver of Spinco’s obligation to deliver an Unqualified Tax Opinion or obtain a Post-Distribution Ruling shall limit or modify Parent’s or Spinco’s continuing indemnification obligation Pursuant to Article V.

ARTICLE XIV

INDEMNITY OBLIGATIONS

Section 14.1 Indemnity Obligations.

(a) Remainco shall indemnify and hold harmless Spinco from and against, and will reimburse Spinco for, (i) all liability for Taxes allocated to Remainco pursuant to Article II, (ii) all Taxes and Tax-Related Losses attributable thereto arising out of, based upon, or relating or attributable to any breach of or inaccuracy in, or failure to perform, as applicable, any representation, covenant, or obligation of any member of the Remainco Group pursuant to this Agreement, (iii) the amount of any Refund received by any member of the Remainco Group that is allocated to Spinco pursuant to Section 2.7(a) and (iv) any Distribution Taxes and Tax-Related Losses attributable to a Remainco Disqualifying Action.

(b) Except as otherwise provided in Section Error! Reference source not found., without regard to whether an Unqualified Tax Opinion may have been provided, any Post-Distribution Ruling obtained or whether any action is permitted or consented to hereunder and notwithstanding anything else to the contrary contained herein, in the Separation Agreement, the Merger Agreement or other Ancillary Agreement, Parent and Spinco shall indemnify and hold harmless Remainco from and against, and will reimburse Remainco for, (i) all liability for Taxes allocated to Spinco pursuant to Article II, (ii) all Taxes and Tax-Related Losses attributable thereto arising out of, based upon, or relating or attributable to any breach of or inaccuracy in, or failure to perform, as applicable, any representation, covenant, or obligation of any member of the Spinco Group pursuant to this Agreement, (iii) the amount of any Refund received by any member of the Spinco Group that is allocated to Remainco pursuant to Section 2.7(a) and (iv) any Distribution Taxes and Tax-Related Losses attributable to a Spinco Disqualifying Action .

(c) Except as otherwise provided in Section Error! Reference source not found., if any Distribution Taxes are (i) not attributable to either a Remainco Disqualifying Action or a Spinco Disqualifying Action or (ii) attributable to both a Remainco Disqualifying Action and a Spinco Disqualifying Action, then Remainco shall bear fifty percent (50%) and Parent and Spinco shall bear fifty percent (50%) of such Distribution Taxes and corresponding Tax-Related Losses.

(d) If any Distribution Taxes or Tax-Related Losses attributable thereto are attributable to any action or transaction constituting a Spinco Disqualifying Action with respect to which Spinco obtains both (i) the prior written consent of Remainco in satisfaction of Section 4.2(d)(iii) and (ii) either an Unqualified Tax Opinion in form and substance reasonably satisfactory to Remainco in satisfaction of Section 4.2(d)(i) or a Post-Distribution Ruling in satisfaction of Section 4.2(d)(ii), then Remainco shall bear fifty percent (50%) and Parent and Spinco shall bear fifty percent (50%) of such Distribution Taxes and corresponding Tax-Related Losses.

Section 14.2 Indemnification Payments.

(a) Except as otherwise provided in this Agreement, if either Party (the “Indemnitee”) is required to pay to a Taxing Authority a Tax or to another Person a payment in respect of a Tax that the other Party (the “Indemnifying Party”) is liable for under this Agreement, including as the result of a Final Determination, the Indemnitee shall notify the Indemnifying Party, in writing, of its obligation to pay such Tax and, in reasonably sufficient detail, its calculation of the amount due by such Indemnifying Party to the Indemnitee, including any Tax-Related Losses attributable thereto. The Indemnifying Party shall pay such amount, including any Tax-Related Losses attributable thereto, to the Indemnitee no later than the later of (i) five (5) Business Days prior to the date on which such payment is due to the applicable Taxing Authority or (ii) thirty (30) Business Days after the receipt of notice from the other Party. Any Tax indemnity payment required to be made pursuant to this Agreement shall be reduced by any corresponding Tax Benefit payment required to be made to the Indemnifying Party by the Indemnitee pursuant to Section 2.8. For the avoidance of doubt, a Tax Benefit payment is treated as corresponding to a Tax indemnity payment to the extent the Tax Benefit realized is directly attributable to the same Tax item (or adjustment of such Tax item pursuant to a Final Determination) that gave rise to the Tax indemnity payment.

(b) If, as a result of any change or redetermination, any amount previously allocated to and borne by one Party pursuant to the provisions of Article II is thereafter allocated to the other Party, then, no later than thirty (30) Business Days after such change or redetermination, such other Party shall pay to such Party the amount previously borne by such Party which is allocated to such other Party as a result of such change or redetermination.

(c) If an Indemnitee receives a Refund with respect to a Tax Contest for which the Indemnifying Party made an indemnity payment to the Indemnitee pursuant to Section 5.2(a), the Indemnitee shall pay the amount of such Refund to the Indemnifying Party, such payment to the Indemnifying Party not to exceed such indemnity payment, no later than thirty (30) Business Days after the receipt of such Refund.

Section 14.3 Payment Mechanics.

(a) All payments under this Agreement shall be made by Remainco directly to Spinco and by Spinco directly to Remainco; provided, however, that if the Parties mutually agree with respect to any such indemnification payment, any member of the Remainco Group, on the one hand, may make such indemnification payment to any member of the Spinco Group, on the other hand, and vice versa. All indemnification payments shall be treated in the manner described in Section 5.4.

(b) In the case of any payment of Taxes made by a Responsible Party or Indemnitee pursuant to this Agreement for which such Responsible Party or Indemnitee, as the case may be, has received a payment from the other Party, such Responsible Party or Indemnitee shall provide to the other Party a copy of any official government receipt received with respect to the payment of such Taxes to the applicable Taxing Authority (or, if no such official governmental receipts are available, executed bank payment forms or other reasonable evidence of payment).

Section 14.4 Treatment of Payments. The Parties agree that any payment made among the Parties pursuant to this Agreement (other than any payment of interest accruing after the Distribution Date) shall be treated, to the extent permitted by Law, for all U.S. federal income tax purposes as either (i) a non-taxable contribution by Remainco to Spinco or (ii) a distribution by Spinco to Remainco, and, with respect to any payment made among the Parties pursuant to this Agreement after the Distribution, such payment shall be treated as having been made immediately prior to the Distribution.

ARTICLE XV

TAX CONTESTS

Section 15.1 Notice. Each Party shall notify the other Party in writing within ten (10) Business Days after receipt by such Party or any member of its Group of a written communication from any Taxing Authority with respect to any pending or threatened audit, claim, dispute, suit, action, proposed assessment or other proceeding (a “Tax Contest”) concerning any Taxes for which the other Party may be liable pursuant to this Agreement, and thereafter shall promptly forward or make available to such Party copies of notices and communications relating to such Tax Contest.

Section 15.2 Separate Returns.

(a) If, pursuant to Article II hereof, Spinco has sole liability for the Taxes that are the subject of a Tax Contest with respect to any Separate Return, then subject to Section 6.5 and Section 6.6, Spinco shall have the sole responsibility and right to control the prosecution of such Tax Contest, including the exclusive right to communicate with agents of the applicable Taxing Authority and to control, resolve, settle, or agree to any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of such Tax Contest.

(b) With respect to any Tax Contest other than those described in Section 6.2(a), subject to Section 6.5 or Section 6.6, Remainco shall have the sole responsibility and right to control the prosecution of such Tax Contest, including the exclusive right to communicate with agents of the applicable Taxing Authority and to control, resolve, settle, or agree to any deficiency, claim or adjustment proposed, asserted or assessed in connection with or as a result of such Tax Contest.

Section 15.3 Joint Return. In the case of any Tax Contest with respect to any Joint Return, Remainco shall, subject to Section 6.5 and Section 6.6, have the sole responsibility and right to control the prosecution of such Tax Contest, including the exclusive right to communicate with agents of the applicable Taxing Authority and to control, resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted, or assessed in connection with or as a result of such Tax Contest.

Section 15.4 Obligation of Continued Notice. During the pendency of any Tax Contest or threatened Tax Contest, each of the Parties shall provide prompt notice to the other Party of any written communication received by it or a member of its respective Group from a Taxing Authority regarding any Tax Contest for which it is indemnified by the other Party hereunder or for which it may be required to indemnify the other Party hereunder. Such notice shall attach copies of the pertinent portion of any written communication from a Taxing Authority and contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any notice and other documents received from any Taxing Authority in respect of any such matters. Such notice shall be provided in a reasonably timely fashion; provided, however, that in the event that timely notice is not provided, a Party shall be relieved of its obligation to indemnify the other Party only to the extent that such delay results in actual increased costs or actual prejudice to such other Party.

Section 15.5 Settlement Rights. Unless waived by the Parties in writing, in connection with any potential adjustment in a Tax Contest as a result of which adjustment the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment to the Controlling Party under this Agreement: (i) the Controlling Party shall keep the Non-Controlling Party informed in a timely manner of all actions taken or proposed to be taken by the Controlling Party with respect to such potential adjustment in such Tax Contest; (ii) the Controlling Party shall timely provide the Non-Controlling Party with copies of any correspondence or filings submitted to any Taxing Authority or judicial authority in connection with such potential adjustment in such Tax Contest; (iii) the Controlling Party shall defend such Tax Contest diligently and in good faith; and (iv) the Controlling Party shall not settle or agree to any deficiency, claim or adjustment proposed, asserted or assessed without the prior written consent of the Non-Controlling Party (not to be unreasonably withheld, conditioned or delayed). The failure of the Controlling Party to take any action specified in the preceding sentence with respect to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement, except to the extent the Non-Controlling Party is actually harmed thereby, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party.

Section 15.6 Tax Contest Participation. Unless waived by the Parties in writing, the Controlling Party shall provide the Non-Controlling Party with written notice reasonably in advance of, and the Non-Controlling Party shall have the right to attend and participate in, any formally scheduled meetings with Taxing Authorities or hearings or proceedings before any judicial authorities in connection with any potential adjustment in a Tax Contest pursuant to which the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment to the Controlling Party under this Agreement (including any Tax Contest related to the Tax-Free Status of the Transactions) or may reasonably be expected to give rise to Tax liabilities of the Non-Controlling Party for any Post-Distribution Period. The failure of the Controlling Party to provide any notice specified in this Section 6.6 to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement except to the extent that the Non-Controlling Party was actually harmed by such failure, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party.

ARTICLE XVI

(a) Each Party shall fully cooperate, and shall cause all members of such Party’s Group to fully cooperate, with all reasonable requests in writing from the other Party, or from an agent, representative or advisor to such Party, in connection with the preparation and filing of any Tax Return, claims for Refunds, the conduct of any Tax Contest, and calculations of amounts required to be paid pursuant to this Agreement, in each case, related or attributable to or arising in connection with Taxes of either Party or any member of either Party’s Group covered by this Agreement and the establishment of any reserve required in connection with any financial reporting (a “Tax Matter”). Such cooperation shall include the provision of any information reasonably necessary or helpful in connection with a Tax Matter and shall include, without limitation, at each Party’s own cost:

(i) the provision of any Tax Returns of either Party or any member of either Party’s Group, books, records (including information regarding ownership and Tax basis of property), documentation and other information relating to such Tax Returns, including accompanying schedules, related work papers, and documents relating to rulings or other determinations by Taxing Authorities; and

ARTICLE XVII

RETENTION OF RECORDS; ACCESS

Section 17.1 Retention of Records. For so long as the contents thereof may become material in the administration of any matter under applicable Tax Law, but in any event until the later of (i) sixty (60) days after the expiration of any applicable statutes of limitation (including any waivers or extensions thereof) and (ii) seven (7) years after the Distribution Date, the Parties shall retain records, documents, accounting data and other information (including computer data)

ARTICLE XVIII

DISPUTE RESOLUTION

Section 18.1 Dispute Resolution. In the event of any dispute between the Parties as to any financial matter covered by this Agreement, the Parties shall appoint a nationally recognized independent public accounting firm (the “Accounting Firm”) to resolve such dispute. In this regard, the Accounting Firm shall make determinations with respect to the disputed items based solely on representations made by Remainco, Spinco, Parent, and their respective representatives, and not by independent review, and shall function only as an expert and not as an arbitrator and shall be required to make a determination in favor of one Party only. The Parties shall require the Accounting Firm to resolve all disputes no later than ninety (90) days after the submission of such dispute to the Accounting Firm, but in no event later than the due date for the payment of Taxes or the filing of the applicable Tax Return, if applicable, and agree that all decisions by the Accounting Firm with respect thereto shall be final and conclusive and binding on the Parties. The Accounting Firm shall resolve all disputes in a manner consistent with this Agreement and, to the extent not inconsistent with this Agreement, in a manner consistent with the Past Practices of Remainco and its Subsidiaries, except as otherwise required by applicable Law. The Parties shall require the Accounting Firm to render all determinations in writing and to set forth, in reasonable detail, the basis for such determination. The fees and expenses of the Accounting Firm shall be borne equally by Remainco, on the one hand, and Parent and Spinco, on the other hand.

ARTICLE XIX

Capitalized terms used in this Agreement, but not otherwise defined in this Agreement, the Separation Agreement or the Merger Agreement, shall have the meaning set forth in Section 1.1.

W I T N E S S E T H:

WHEREAS, the Company, acting through its direct and indirect Subsidiaries, currently conducts the Company Retained Business and the SpinCo Business;

NO PARTY TO THIS AGREEMENT SHALL SEEK A JURY TRIAL IN ANY LAWSUIT, PROCEEDING, COUNTERCLAIM OR ANY OTHER LITIGATION PROCEDURE BASED UPON, OR ARISING OUT OF, THIS AGREEMENT OR ANY RELATED INSTRUMENTS. NO PARTY WILL SEEK TO CONSOLIDATE ANY SUCH ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. EACH PARTY TO THIS AGREEMENT CERTIFIES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT OR INSTRUMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS SET FORTH ABOVE IN THIS SECTION 8.12. NO PARTY HAS IN ANY WAY AGREED WITH OR REPRESENTED TO ANY OTHER PARTY THAT THE PROVISIONS OF THIS SECTION 8.12 WILL NOT BE FULLY ENFORCED IN ALL INSTANCES.

8.13 Severability. If any provision of this Agreement, or the application of any such provision to any Person or circumstance, shall be held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision hereof.

8.14 Interpretation. The Parties have participated jointly in the negotiation and drafting of this Agreement. This Agreement shall be construed without regard to any presumption or rule requiring construction or interpretation against the Party drafting or causing any instrument to be drafted.

8.15 No Duplication; No Double Recovery. Nothing in this Agreement is intended to confer to or impose upon any Party a duplicative right, entitlement, obligation or recovery with respect to any matter arising out of the same facts and circumstances.

8.16 No Waiver. No failure to exercise and no delay in exercising, on the part of any Party, any right, remedy, power or privilege hereunder shall operate as a waiver hereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

8.17 No Admission of Liability. The allocation of Assets and Liabilities herein is solely for the purpose of allocating such Assets and Liabilities among the Parties and is not intended as an admission of liability or responsibility for any alleged Liabilities vis-à-vis any third party, including with respect to the Liabilities of any non-wholly owned subsidiary of any Party.

TRANSITION SERVICES PROVIDED

2.1 Transition Services.

(a) Upon the terms and subject to the conditions set forth in this Agreement, Provider shall provide, or cause one or more of its Representatives to provide, to Recipient each of the services set forth on Schedule A attached hereto (hereinafter referred to individually as a “Transition Service”, and collectively as the “Transition Services”), at the corresponding costs set forth on Schedule A, and Recipient agrees to receive the Transition Services and pay the costs therefor during the time period specified for each such Transition Service in such Schedule or for such other time period as permitted pursuant to this Agreement (hereinafter referred to collectively as the “Service Periods” for all of the Transition Services, and individually a “Service Period” for each Transition Service). The Parties may amend the scale and scope of the Transition Services from time to time upon mutual agreement by executing a signed amendment to Schedule A.

(b) If, within three (3) months following the Effective Date, Recipient identifies in good faith any service that was provided by Provider or one of its Affiliates (excluding the OmniAb Group) to the OmniAb Business during the six (6) month period (or twelve (12) month period solely with respect to activities that are customarily performed on an annual basis) prior to the Effective Date that is not listed on Schedule A and is necessary to effectuate the Separation (an “Omitted Service”), then Recipient shall notify Provider thereof and Schedule A will be deemed amended to include such Omitted Service.

2.2 Personnel; Affiliates; Vendors. In providing the Transition Services, Provider may, as it deems necessary or appropriate, (i) use the qualified personnel of Provider or its Affiliates, and (ii) employ the services of qualified third parties (“Vendors”) to the extent that, and subject to the condition that, such Vendor’s services (A) were utilized by or for the benefit of the OmniAb Business prior to the Effective Date, (B) are routinely utilized to provide similar services to other businesses of Provider or (C) are reasonably necessary for the efficient performance of such Transition Services. Furthermore, each Party shall, and shall cause its Representatives to, comply, in all material respects, with all Laws which may be applicable to the Transition Services. Each Party shall be responsible for its Representatives, including for such Representatives adhering to any health, safety, and security regulations and other published policies of the other Party while on the other Party’s premises or when given access to any equipment, computer, databases, systems, software, network or other files (collectively, “Systems”) owned or controlled by the other Party. If a Party or one or more of its Representatives needs access to the premises or Systems of the other Party or one or more of its Representatives to provide or receive the Transition Services (as applicable), then (x) the accessing Party shall advise the other Party in writing in advance of such access of the name of each of the accessing Party’s Representatives who shall require such access, (y) the accessing Party and its Representatives shall not attempt to obtain access to, use or interfere with any of the premises or Systems of the other Party or such other Party’s Representatives, except to the extent permitted by the other Party or required to do so to provide or receive the Transition Services (as applicable), and (z) the accessing Party and its Representatives shall not intentionally damage, disrupt or impair the normal operation of any of the premises or Systems of the other Party or such other Party’s Representatives.

2.3 Coordinators. Each of Provider and Recipient shall nominate a representative to act as its primary contact person to coordinate the provision of all Transition Services (collectively, the “Primary Coordinators”). Each Primary Coordinator may designate one or more service coordinators for each specific Transition Service (the “Service Coordinators”). Each Party may treat an act of a Primary Coordinator or Service Coordinator of another Party as being authorized by such other Party without inquiring behind such act or ascertaining whether such Primary Coordinator or Service Coordinator had authority to so act, provided, however, that no such Primary Coordinator or Service Coordinator has authority to amend this Agreement. Provider and Recipient shall advise each other promptly (in any case no more than five (5) business days) in writing of any change in the Primary Coordinators and any Service Coordinator for a particular Transition Service, setting forth the name of the Primary Coordinator or Service Coordinator to be replaced and the name of the replacement, and certifying that the replacement Primary Coordinator or Service Coordinator is authorized to act for such Party in all matters relating to this Agreement, in the case of a Primary Coordinator or, in the case of a Service Coordinator, with respect to the Transition Service for which such Service Coordinator has been designated. Provider and Recipient each agrees that all communications relating to the provision of the Transition Services shall be directed to the Service Coordinators for such Transition Service with copies to the Primary Coordinators. Provider’s initial Primary Coordinator shall be Matthew Korenberg. Recipient’s initial Primary Coordinator shall be Matt Foehr.

2.4 Level of Transition Services.

(a) Recipient acknowledges and agrees that Provider is not in the business of providing services to third parties and is entering into this Agreement only in connection with the Separation and Distribution Agreement. Provider shall, and shall cause each of its Representatives to, provide the Transition Services with substantially the same degree of skill, quality and standard of care as that utilized by Provider (or its Affiliates) to perform similar activities in the six (6) month period (or twelve (12) month period solely with respect to activities that are customarily performed on an annual basis) prior to the Effective Date, and, in any event, no less than with commercially reasonable care and diligence (collectively, the “Services Standard”). Under no circumstances shall Provider or any of its Representatives be held accountable to a greater standard of care, efforts or skill than the Services Standard in the performance of the Transition Services. Recipient acknowledges and agrees that (i) the Transition Services do not include the exercise of business judgment or general management for Provider and (ii) NEITHER PROVIDER NOR ANY OF ITS AFFILIATES MAKES ANY REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, WITH RESPECT TO THE TRANSITION SERVICES.

(b) If the Transition Services to be provided to Recipient materially increase in scale or in scope as compared to the level of the similar services provided in connection with the operation of the OmniAb Business as of the Effective Date, Provider may, at its election, choose to not provide such increased scale or scope of Transition Services, and if Provider elects to perform such increased scale or scope of Transition Services, all costs incurred in connection therewith shall be mutually agreed upon by Provider and Recipient prior to the time such additional Transition Services are performed, shall be set forth in an amended Schedule A, and shall be borne by Recipient.

(c) In addition to being subject to the terms and conditions of this Agreement for the provision of the Transition Services, Provider and Recipient each agree that the Transition Services provided by any Vendor shall be subject to the terms and conditions of any agreements between Provider and such Vendor, which agreements shall be on substantially the same conditions as Provider would enter into with such Vendor for its own account, and no such agreements shall be binding on Recipient after the Term hereof without Recipient’s express written consent. Provider shall consult with Recipient concerning the terms and conditions of any such agreements to be entered into, or proposed to be entered into, or amended, with any Vendors after the Effective Date.

(d) Without relieving Provider of its obligation to perform the Transition Services in accordance with the Services Standard, Provider shall not be (i) obligated to perform the Transition Services to the extent that such performance would be unlawful or that would require Provider to violate applicable Law; (ii) obligated to perform the Transition Services to the extent that such performance, in Provider’s reasonable determination, could create deficiencies in Provider’s controls over financial information or adversely affect the maintenance of Provider’s financial books and records or the preparation of its financial statements; (iii) obligated to hire any additional employees to perform the Transition Services or maintain the employment of any specific employee; (iv) obligated to hire replacements for employees that resign, retire or are terminated; (v) obligated to enter into retention agreements with employees or otherwise provide any incentive beyond payment of regular salary and benefits; (vi) prevented from transferring after the Effective Date any employees who were supporting the business operations as of the Effective Date to support other business operations for Provider or its Affiliates or to assume other roles with Provider or its Affiliates to the extent such employees are not required to provide Transition Services; (vii) prevented from determining, in its sole discretion, the individual employees who will provide Transition Services; or (viii) obligated to purchase, lease or license any additional equipment or software.

2.5 Transitional Nature of Services. Recipient acknowledges and agrees that the Transition Services are intended only to be transitional in nature, and shall be furnished by Provider only during the Service Periods. Recipient shall use commercially reasonable efforts to have sufficient resources available to it at the end of the Service Periods to perform the Transition Services (or have the Transition Services performed) without the involvement of Provider, its Affiliates or any of its or their respective employees or agents upon the termination or expiration of a Service Period for an applicable Transition Service.

2.6 Location of Services Provided; Travel Expenses. Provider shall provide the Transition Services to Recipient from locations of Provider’s choice in its sole discretion except to the extent the nature of the Transition Services necessitates performance at a specific location, as mutually agreed upon by the Parties. Subject to Section 3.1, should the provision of the Transition Services require any directors, officers, employees, agents, representatives, or subcontractors of Provider or its Affiliates to travel beyond fifty (50) miles from his or her employment location, Recipient shall reimburse Provider for all reasonable travel-related out-of-pocket costs, consistent with Provider’s travel policy as provided to Recipient in advance in writing.

2.7 Limitation of Liability.

The Parties hereto acknowledge and agree that the Transition Services are provided by Provider: (a) at the request of Recipient in order to accommodate it following the closing under the Separation and Distribution Agreement; (b) at the costs set forth on Schedule A hereto and with no expectation of profit being made by Provider thereon; and (c) with the expectation that Provider is not assuming any financial or operational risks, including those usually assumed by a service provider, except for those risks explicitly set forth herein. Accordingly, each Party agrees that, absent gross negligence or willful misconduct, and except for breaches of Article V (Confidentiality) and except for a Party’s obligations under Section 2.8 (Indemnification), the other Party, its Affiliates and their directors, officers, employees, representatives, consultants and agents shall not be liable for any indirect, special, incidental or consequential damages, including lost profits or savings, whether or not such damages are foreseeable, or for any third party claims relating to the Transition Services or each Party’s performance under this Agreement. Notwithstanding anything to the contrary contained herein, in the event Provider commits an error with respect to or incorrectly performs or fails to perform any Transition Service, at Recipient’s request, Provider shall use commercially reasonable efforts and in good faith attempt to correct such error, re-perform or perform such Transition Service at no additional cost to Recipient; provided that, absent gross negligence or willful misconduct, and assuming that Provider uses commercially reasonable data backup processes, Provider shall have no obligation to recreate any lost or destroyed data to the extent the same cannot be cured by the re-performance of the Transition Service in question.

2.8 Indemnification.

(a) Recipient shall indemnify, defend and hold harmless Provider and its Affiliates and its and their respective officers, directors, employees, representatives, subcontractors and agents from and against any and all damages, liabilities, losses, taxes, fines, penalties, costs and expenses (including, without limitation, reasonable fees of counsel) incurred by any of them in connection with any Third Party Claim (as defined below) (each, a “Loss” and, collectively, the “Losses”) relating to, arising out of or resulting from or based on (i) Recipient’s material breach of this Agreement or (ii) any gross negligence or willful misconduct of Recipient, (iii) Provider’s provision of the Transition Services as directed or requested by Recipient, or (iv) Recipient’s use or exploitation of any work product provided by Provider in the performance of the Transition Services, except in each case (i), (ii), (iii), and (iv) to the extent such Losses are subject to indemnification pursuant to Section 2.8(b).

(b) Provider hereby agrees to indemnify, defend and hold harmless Recipient and its Affiliates and its and their respective officers, directors, employees, representatives, subcontractors and agents from and against any and all Losses relating to, arising out of or resulting from (i) Provider’s material breach of this Agreement or (ii) any gross negligence or willful misconduct in the performance of its obligations under this Agreement, except in each case of (i) and (ii) to the extent such Losses are subject to indemnification pursuant to Section 2.8(a).

(c) To the maximum extent permitted by applicable Law, each Party’s and its Affiliates’ and each of its and their respective subcontractors’ officers’, directors’, employees’ and agents’ sole and exclusive remedy with respect to any and all claims relating to the Transition Services shall be pursuant to the indemnification provisions set forth in this Section 2.8.

2.9 Indemnification Procedures.

(a) If any claim or demand is made by a third party (including any action or proceeding commenced or threatened to be commenced) with respect to which a Party seeking indemnification (the “Indemnified Party”) intends to seek indemnity under Section 2.8 (a “Third Party Claim”), the Indemnified Party shall promptly give written notice thereof to the other Party (the “Indemnifying Party”) indicating, with reasonable specificity, the nature of such Third Party Claim, the basis therefor, and a copy of any documentation received from such third party. A failure by the Indemnified Party to give notice and to tender the defense of any action or proceeding in a timely manner pursuant to this Section 2.9(a) shall not limit the obligation of the Indemnifying Party under Section 2.8, except to the extent such Indemnifying Party is actually and materially prejudiced thereby.

(b) Upon receipt of a notice for indemnity from the Indemnified Party pursuant to Section 2.9(a) with respect to any Third Party Claim, the Indemnifying Party shall have the right to assume the defense of, at its own expense and by its own counsel, any such Third Party Claim. If the Indemnifying Party shall, in accordance with the immediately preceding sentence, undertake to compromise or defend any such Third Party Claim, it shall notify the Indemnified Party of its intention to do so, and the Indemnified Party shall agree to cooperate with the Indemnifying Party and its counsel in the compromise of, or defense against, any such Third Party Claim; provided that the Indemnifying Party shall not settle or compromise any such Third Party Claim without the written consent of the Indemnified Party (not to be unreasonably withheld, conditioned or delayed) unless such settlement or compromise fully and irrevocably releases the Indemnified Party in connection with such Third Party Claim and provides relief consisting solely of money damages borne by the Indemnifying Party. Notwithstanding an election of the Indemnifying Party to assume the defense of such Third Party Claim, the Indemnified Party shall have the right to employ separate legal counsel, its own cost and expense, and to participate in the defense thereof.

2.10 Modification of Transition Services Procedures.

(a) Subject to the procedure set forth in this Section 2.10 to the extent applicable, Provider may make changes from time to time in its standards and procedures for performing the Transition Services, provided that any such change shall not interfere in any material respect with the continued provision or cost of the Transition Services. Notwithstanding the foregoing sentence, unless required by Law, Provider shall not implement any substantial or material changes to such standards and procedures in a manner affecting the operation of the OmniAb Business unless Recipient agrees in writing to such changes and Provider gives Recipient ten (10) business days to adapt its operations to accommodate such changes to the extent commercially reasonable.

(b) During the term of this Agreement, if Recipient intends to make any changes that may affect the provision of any of the Transition Services, Recipient shall provide Provider with a plan identifying any changes as soon as reasonably practicable, but in any case no less than ten (10) business days before implementing such changes; provided, however, that Provider shall not be required to alter the method in which it provides any of the Transition Services or increase the level of any such Transition Services in any material manner except as expressly provided herein; provided, further, however, that the failure of Recipient to provide such notice shall not alter or diminish Provider’s obligations to provide the Transition Services on the terms set forth herein except where the failure to provide notice has materially increased Provider’s cost or burden to provide such Transition Service.

2.11 Cooperation. The Parties will use commercially reasonable efforts to reasonably cooperate and cause each of their respective Representatives to reasonably cooperate in a professional and workmanlike manner with each other to the extent necessary to assist the other Party in performance of its obligations under this Agreement, including with respect to the provision and receipt of the Transition Services. Such cooperation shall include exchanging information relevant to and reasonably necessary for the provision or receipt of the Transition Services hereunder and the performance of such other duties and tasks as may be reasonably required for the provision or receipt of the Transition Services. Without limiting the foregoing:

(a) Recipient shall permit Provider and its Representatives reasonable access during regular business hours (or otherwise upon reasonable prior notice) to any data, records and personnel involved in receiving or overseeing the Transition Services as reasonably requested by Provider to facilitate Provider’s performance of this Agreement. Any such data and records shall be subject to Article V. Before the Parties exchange any Personal Information in connection with the Transition Services, the Parties will enter into a data processing agreement in accordance with applicable Laws.

(b) Provider shall use commercially reasonable efforts to obtain any consents, licenses, waivers or approvals necessary to permit Provider to perform its obligations hereunder; provided, however, that under no circumstances shall Provider be obligated to provide the relevant part of any Transition Services to the extent that (i) Provider is unable to obtain necessary third party consents, licenses, waivers or approvals relating to such part of the Transition Services on commercially reasonable terms, (ii) in order to provide such part of the Transition Services, Provider will have an obligation to make any payments to any Third Party or incur any obligations in respect of any such consents, licenses, waivers or approvals, which payments are not subject to reimbursement by Recipient or which other obligations are not assumed by Recipient hereunder, (iii) Provider would be obligated to make any alternative arrangements in the event that any such consents, licenses, waivers or approvals are not obtained (but only to the extent such arrangements would not be commercially reasonable) or (iv) Provider would be required to seek broader rights or more favorable terms with respect to any consents, licenses, waivers or approvals than those applicable immediately prior to the date hereof where the costs of obtaining the same are not subject to reimbursement by Recipient.

(c) Recipient shall obtain all necessary consents, licenses, waivers and approvals necessary for it to receive the Transition Services and perform its obligations under this Agreement.

6.4 Accrued Rights. Termination or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of a Party prior to such termination or expiration. Such termination or expiration shall not relieve a Party from obligations that are expressly indicated to survive the termination or expiration of this Agreement.

During the term of this Agreement and for one (1) year thereafter (or such longer period as may be required by applicable Law), Provider and Recipient shall each use commercially reasonable efforts to maintain complete and accurate records related to any Transition Service provided, fees invoiced and payments made hereunder (the “Service Records”). Recipient may request a certified audit of Provider’s Service Records from the date of commencement of the Transition Services to be performed by an independent certified public accountant which (a) is reasonably acceptable to Provider and (b) may not be compensated on a contingency basis or otherwise have any financial interest in the outcome of such audit. Any such audit shall be at the expense of Recipient. Recipient may not request such an audit more than one (1) time within any twelve (12) month period with respect to any particular Transition Service. The accountant shall be required to execute a confidentiality and non-disclosure agreement if requested by Provider and shall hold all information confidential. The accountant may reveal to Recipient only the amounts of any underpayment or under reimbursement, or overbilling, as applicable. The accountant shall provide to Provider a final report of its work, including both overbilling and underpayment information. The audit shall take place during normal business hours and upon reasonable notice and such accountant shall use commercially reasonable efforts to minimize interference with the normal business activities of Provider. If any audit reveals an overpayment by Recipient, Provider shall promptly refund to Recipient any such overpayment. In addition, if any audit reveals an overpayment by Recipient exceeding five percent (5%) during the audited period, Provider shall reimburse Recipient for the costs of conducting such audit. If any audit reveals an underpayment by Recipient, Recipient shall promptly pay Provider such underpayment amount.

Furthermore, each Party shall, and shall cause its Representatives to, comply, in all material respects, with all Laws which may be applicable to the Transition Services. Each Party shall be responsible for its Representatives, including for such Representatives adhering to any health, safety, and security regulations and other published policies of the other Party while on the other Party’s premises or when given access to any equipment, computer, databases, systems, software, network or other files (collectively, “Systems”) owned or controlled by the other Party.

Each Party may treat an act of a Primary Coordinator or Service Coordinator of another Party as being authorized by such other Party without inquiring behind such act or ascertaining whether such Primary Coordinator or Service Coordinator had authority to so act, provided, however, that no such Primary Coordinator or Service Coordinator has authority to amend this Agreement. Provider and Recipient shall advise each other promptly (in any case no more than five (5) business days) in writing of any change in the Primary Coordinators and any Service Coordinator for a particular Transition Service, setting forth the name of the Primary Coordinator or Service Coordinator to be replaced and the name of the replacement, and certifying that the replacement Primary Coordinator or Service Coordinator is authorized to act for such Party in all matters relating to this Agreement, in the case of a Primary Coordinator or, in the case of a Service Coordinator, with respect to the Transition Service for which such Service Coordinator has been designated.

9.5 Transitional Nature of Services. Recipient acknowledges and agrees that the Transition Services are intended only to be transitional in nature, and shall be furnished by Provider only during the Service Periods. Recipient shall use commercially reasonable efforts to have sufficient resources available to it at the end of the Service Periods to perform the Transition Services (or have the Transition Services performed) without the involvement of Provider, its Affiliates or any of its or their respective employees or agents upon the termination or expiration of a Service Period for an applicable Transition Service.

9.6 Location of Services Provided; Travel Expenses. Provider shall provide the Transition Services to Recipient from locations of Provider’s choice in its sole discretion except to the extent the nature of the Transition Services necessitates performance at a specific location, as mutually agreed upon by the Parties. Subject to Section 3.1, should the provision of the Transition Services require any directors, officers, employees, agents, representatives, or subcontractors of Provider or its Affiliates to travel beyond fifty (50) miles from his or her employment location, Recipient shall reimburse Provider for all reasonable travel-related out-of-pocket costs, consistent with Provider’s travel policy as provided to Recipient in advance in writing.

The Parties will use commercially reasonable efforts to reasonably cooperate and cause each of their respective Representatives to reasonably cooperate in a professional and workmanlike manner with each other to the extent necessary to assist the other Party in performance of its obligations under this Agreement, including with respect to the provision and receipt of the Transition Services.

During the Term, Provider shall carry commercially appropriate and customary levels of insurance with a reputable insurance provider covering business interruptions and general liability insurance (including errors & omissions and contractual liability) to protect its own business and property interests.

14.17 Audit. During the term of this Agreement and for one (1) year thereafter (or such longer period as may be required by applicable Law), Provider and Recipient shall each use commercially reasonable efforts to maintain complete and accurate records related to any Transition Service provided, fees invoiced and payments made hereunder (the “Service Records”). Recipient may request a certified audit of Provider’s Service Records from the date of commencement of the Transition Services to be performed by an independent certified public accountant which (a) is reasonably acceptable to Provider and (b) may not be compensated on a contingency basis or otherwise have any financial interest in the outcome of such audit. Any such audit shall be at the expense of Recipient. Recipient may not request such an audit more than one (1) time within any twelve (12) month period with respect to any particular Transition Service.

The accountant shall provide to Provider a final report of its work, including both overbilling and underpayment information. The audit shall take place during normal business hours and upon reasonable notice and such accountant shall use commercially reasonable efforts to minimize interference with the normal business activities of Provider. If any audit reveals an overpayment by Recipient, Provider shall promptly refund to Recipient any such overpayment. In addition, if any audit reveals an overpayment by Recipient exceeding five percent (5%) during the audited period, Provider shall reimburse Recipient for the costs of conducting such audit. If any audit reveals an underpayment by Recipient, Recipient shall promptly pay Provider such underpayment amount.

REGISTRATIONS

2.1 Piggyback Registration.

2.1.1 Piggyback Rights. If, at any time on or after the date hereof, the Company proposes to file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company), other than a Registration Statement (i) filed in connection with any employee share option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) pursuant to a Registration Statement on Form S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto), (iv) for an offering of debt that is convertible into equity securities of the Company or (v) for a dividend reinvestment plan, then the Company shall give written notice of such proposed filing to all of the Holders of Registrable Securities as soon as practicable but not less than seven (7) days before the anticipated filing date of such Registration Statement, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to register the sale of such number of Registrable Securities as such Holders may request in writing within three (3) business days after receipt of such written notice (such Registration a “Piggyback Registration”). The Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use its commercially reasonable efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable Securities requested by the Holders pursuant to this subsection 2.1.1 to be included in a Piggyback Registration on the same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.1.1 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the Company. The notice periods set forth in this subsection 2.1.1 shall not apply to an Underwritten Shelf Takedown conducted in accordance with subsection 2.2.3.

2.1.2 Reduction of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Registration that is to be a Piggyback Registration (other than Underwritten Shelf Takedown), in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of the shares of Domesticated Parent Common Stock that the Company desires to sell, taken together with (i) the shares of Domesticated Parent Common Stock, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant Section 2.1 hereof, and (iii) the shares of Domesticated Parent Common Stock, if any, as to which Registration has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then:

(a) If the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (A) first, the shares of Domesticated Parent Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection 2.1.1 hereof, pro rata based on the respective number of Registrable Securities that each Holder has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the Holders have requested be included in such Underwritten Registration (such proportion is referred to herein as “Pro Rata”) exercising its rights to register its Registrable Securities pursuant to subsection 2.1.1 hereof, which can be sold without exceeding the

Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the shares of Domesticated Parent Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities;

(b) If the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Company shall include in any such Registration (A) first, the shares of Domesticated Parent Common Stock or other equity securities, if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection 2.1.1, Pro Rata, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the shares of Domesticated Parent Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the shares of Domesticated Parent Common Stock or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number of Securities.

2.1.3 Piggyback Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration. The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this subsection 2.1.3.

2.2 Shelf Registrations.

2.2.1 Initial Registration. The Company shall use commercially reasonable efforts to, within thirty (30) days after the date hereof, file a Registration Statement under the Securities Act to permit the public resale of all the Registrable Securities held by the Holders from time to time as permitted by Rule 415 under the Securities Act (or any successor or similar provision adopted by the Commission then in effect) (“Rule 415”) on the terms and conditions specified in this Section 2.2.1 and shall use its commercially reasonable efforts to cause such Registration Statement to be declared effective as soon as practicable after the filing thereof. The Registration Statement filed with the Commission pursuant to this Section 2.2.1 shall be a shelf registration statement on Form S-1 or such other form of registration statement as is then available to effect a registration for resale of such Registrable Securities, covering such Registrable Securities, and shall contain a Prospectus in such form as to permit any Holder to sell such Registrable Securities pursuant to Rule 415 at any time beginning on the effective date for such Registration Statement. A Registration Statement filed pursuant to this Section 2.2.1 shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holders. The Company shall use its commercially reasonable efforts to cause a Registration Statement filed pursuant to this Section 2.2.1 to remain effective, and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, that another Registration Statement is available, for the resale of all the Registrable Securities held by the Holders until all such Registrable Securities have ceased to be Registrable Securities. As soon as practicable following the effective date of a Registration Statement filed pursuant to this Section 2.2.1, the Company shall notify the Holders of the effectiveness of such Registration Statement. When effective, a Registration Statement filed pursuant to this Section 2.3.1 (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or

necessary to make the statements therein not misleading (in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which such statement is made). In the event the Company files a Shelf on Form S-1, the Company shall use its commercially reasonable efforts to convert the Form S-1 to a shelf registration statement on Form S-3 (“Form S-3”) as soon as practicable after the Company is eligible to use Form S-3.

2.2.2 Subsequent Shelf Registration. If any Shelf ceases to be effective under the Securities Act for any reason at any time while Registrable Securities included thereon are still outstanding or if the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement for any reason at any time while Registrable Securities are still outstanding, the Company shall, subject to Section 3.4, use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including using its commercially reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness of such Shelf) and correct any such Misstatement, and shall use its commercially reasonable efforts to as promptly as is reasonably practicable amend such Shelf in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf or file an additional registration statement (a “Subsequent Shelf Registration”) registering the resale of all Registrable Securities including on such Shelf (determined as of two (2) business days prior to such filing), and pursuant to any method or combination of methods legally available to, and requested by, any Holder. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof and (ii) keep such Subsequent Shelf Registration continuously effective and available for use to permit the Holders named therein to sell their Registrable Securities included therein, and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities included thereon. Any such Subsequent Shelf Registration shall be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on another appropriate form. In the event that any Holder holds Registrable Securities that are not registered for resale on a delayed or continuous basis, the Company, upon written request of a Holder shall promptly use its commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company’s option, a Shelf (including by means of a post-effective amendment) or a Subsequent Shelf Registration and cause the same to become effective as soon as practicable after such filing and such Shelf or Subsequent Shelf Registration shall be subject to the terms hereof; provided, however, the Company shall only be required to cause such Registrable Securities to be so covered once annually after inquiry of the Holder. The Company’s obligation under this Section 2.2.2, shall, for the avoidance of doubt, be subject to Section 3.4.

2.2.3 Requests for Underwritten Shelf Takedowns. Subject to Section 3.4, following the expiration of the applicable Lock-Up Period, the Sponsor may request to sell all or any portion of its Registrable Securities in an underwritten offering that is registered pursuant to the Shelf (each, an “Underwritten Shelf Takedown”); provided that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include securities with a total offering price (including piggy-back securities and before deduction of underwriting discounts) reasonably expected to exceed, in the aggregate, $15,000,000. All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company at least 48 hours prior to the public announcement of such Underwritten Shelf Takedown, which shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown and the expected price range (net of underwriting discounts and commissions) of such Underwritten Shelf Takedown. The Company shall include in any Underwritten Shelf Takedown the securities requested to be included by any Holder (each a “Takedown Requesting Holder”) at least 48 hours prior to the public announcement of such Underwritten Shelf Takedown pursuant to written contractual piggy-back registration rights of such holder (including to those set forth herein). The Sponsor shall have the right to select the underwriter(s) for such offering (which shall consist of one or more reputable nationally recognized investment banks), subject to the Company’s prior approval which shall not be unreasonably withheld, conditioned or delayed. The Sponsor may demand not more than one (1) Underwritten Shelf Takedowns pursuant to this Section 2.2.3 in any six (6)-month period. Notwithstanding anything to the contrary in this Agreement, the Company may effect any Underwritten Offering pursuant to any then effective Registration Statement, including a Form S-3, that is then available for such offering, subject to the provisions of Section 2.1.

2.2.4 Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in good faith, advises the Company, the Sponsor and the Takedown Requesting Holders (if any) in writing that the dollar amount or number of Registrable Securities that the Sponsor and the Takedown Requesting Holders (if any) desire to sell, taken together with all other shares of Domesticated Parent Common Stock or other equity securities that the Company desires to sell, exceeds the Maximum Number of Securities, then the Company shall include in such Underwritten Shelf Takedown, as follows: (i) first, the Registrable Securities of the Sponsor that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the shares of Domesticated Parent Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the shares of Domesticated Parent Common Stock or other equity securities of the Takedown Requesting Holders, if any, that can be sold without exceeding the Maximum Number of Securities, determined Pro Rata based on the respective number of Registrable Securities that each Takedown Requesting Holder has so requested to be included in such Underwritten Shelf Takedown.

2.2.5 Withdrawal. The Sponsor shall have the right to withdraw from an Underwritten Shelf Takedown for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of its intention to withdraw from such Underwritten Shelf Takedown prior to the public announcement of such Underwritten Shelf Takedown. If so withdrawn, a demand for an Underwritten Shelf Takedown shall constitute a demand for an Underwritten Shelf Takedown by the Sponsor for purposes of subsection 2.2.3, unless either (i) the Sponsor has not previously withdrawn any Underwritten Shelf Takedown or (ii) the Sponsor reimburses the Company for all Registration Expenses with respect to such Underwritten Shelf Takedown (or, if there is more than one Takedown Requesting Holders, a pro rata portion of such Registration Expenses based on the respective number of Registrable Securities that each Takedown Requesting Holder has requested be included in such Underwritten Shelf Takedown). Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with an Underwritten Shelf Takedown prior to and including a withdrawal under this subsection 2.2.5, unless the Sponsor elect to pay such Registration Expenses pursuant to clause (ii) of this subsection 2.2.5.

2.3 Market Stand-off. In connection with any Underwritten Offering of equity securities of the Company, if requested by the managing Underwriters, each Holder that is an executive officer, director or Holder in excess of five percent (5%) of the outstanding Common Stock agrees that it shall not Transfer any equity securities of the Company (other than those included in such offering pursuant to this Agreement), without the prior written consent of the Company, during the ninety (90)-day period (or such shorter time agreed to by the managing Underwriters) beginning on the date of pricing of such offering, except as expressly permitted by such lock-up agreement or in the event the managing Underwriters otherwise agree by written consent. Each such Holder that participates and sells Registrable Securities in such Underwritten Offering agrees to execute a customary lock-up agreement in favor of the Underwriters to such effect (in each case on substantially the same terms and conditions as all such Holders that execute a lock-up agreement).

ARTICLE 3

3.1.9 notify the Holders at any time when a Prospectus relating to such Registration Statement is required to be delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in Section 3.4 hereof;

3.1.10 in the event of an Underwritten Offering or a sale by a placement agent or sales agent pursuant to such Registration, permit a representative of the Holders, the Underwriters, if any, and any attorney or accountant retained by such Holders, Underwriter, placement agent or sales agent to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, placement agent, sales agent attorney or accountant in connection with the Registration; provided, however, that such representatives, Underwriters, placement agents, sales agents, attorneys or accountant enter into a confidentiality agreement, in form

and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information; and provided further, that the Company will not include the name of any Holder or any information regarding any Holder not participating in such sale pursuant to such Registration unless required by the Commission or any applicable law, rules or regulations;

3.1.11 obtain a “cold comfort” letter from the Company’s independent registered public accountants in the event of an Underwritten Registration, in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders;

3.1.12 in the event of an Underwritten Offering or a sale by a placement agent or sales agent pursuant to such Registration, on the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of counsel representing the Company for the purposes of such Registration, addressed to the Holders, the placement agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given as the Holders, placement agent, sales agent, or Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters, and reasonably satisfactory to a majority in interest of the participating Holders;

3.1.13 in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing Underwriter of such offering;

3.1.15 with respect to an Underwritten Offering pursuant to Section 2.2.3, if the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $50,000,000, use its commercially reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter in such Underwritten Offering; and

3.1.16 otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the participating Holders, consistent with the terms of this Agreement, in connection with such Registration.

3.3 Requirements for Participation in Underwritten Offerings. Notwithstanding anything in this Agreement to the contrary, if any Holder does not provide the Company with its requested Holder Information, the Company may exclude such Holder’s Registrable Securities from the applicable Registration Statement or Prospectus if the Company determines, based on the advice of counsel, that such information is necessary to effect the Registration. No person may participate in any Underwritten Offering or other offering involving a Registration and an Underwriter for equity securities of the Company pursuant to a Registration initiated by the Company hereunder

unless such person (i) agrees to sell such person’s securities on the basis provided in any arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required under the terms of such arrangements.

3.4 Suspension of Sales; Adverse Disclosure; Restrictions on Registration Rights.

3.4.1 Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, or in the opinion of counsel for the Company it is necessary to supplement or amend such Prospectus to comply with law, each of the Holders shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed.

3.4.2 If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would (i) require the Company to make an Adverse Disclosure, (ii) would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, (iii) in the good faith judgment of the majority of the Board, be seriously detrimental to the Company and the majority of the Board concludes as a result that it is essential to defer such filing, the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities, and in each case maintain the confidentiality of such notice and its contents. The Company shall immediately notify the Holders of the expiration of any period during which it exercised its rights under this subsection 3.4.2.

3.4.3 Subject to subsection 3.4.4, if (i) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred twenty (120) days (or such shorter time as the managing Underwriters may agree) after the effective date of, a Company-initiated Registration and provided that the Company continues to actively employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become effective or maintain the effectiveness of the applicable Registration Statement, or (ii) pursuant to subsection 2.2.3, Holders have requested an Underwritten Shelf Takedown and the Company and Holders are unable to obtain the commitment of underwriters to firmly underwrite such offering, then, in each case, the Company may, upon giving prompt written notice of such action to the Holders, delay any other registered offering pursuant to subsection 2.2.3.

3.4.4 The right to delay or suspend any filing, initial effectiveness or continued use of a Registration Statement pursuant to subsection 3.4.2 or a registered offering pursuant to subsection 3.4.3 shall be exercised by the Company, in either case, for not more than sixty (60) consecutive calendar days or more than one hundred twenty (120) total calendar days during any twelve (12)-month period.

3.4.5 Notwithstanding anything to the contrary set forth herein, the Company shall not be required provide any Holder with any material, nonpublic information regarding the Company other than to the extent that providing notice to such Holder hereunder constitutes material, nonpublic information regarding the Company.

3.5 Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to use commercially reasonable efforts to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings; provided that any documents publicly filed or furnished with the Commission pursuant to the Electronic Data Gathering, Analysis and Retrieval System shall be deemed to have been furnished or delivered to the Holders pursuant to this Section 3.5. The Company further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from

time to time to enable such Holder to sell shares of Domesticated Parent Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule then in effect), including providing any customary legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

3.6 Transfer Restrictions.

3.6.1 Except with respect to a Transfer to a Permitted Transferee, during the applicable Lock-Up Periods, no Existing Holder or New Holder shall, directly or indirectly, (a) offer, sell, contract to sell, pledge, hypothecate, grant any option to purchase, make any short sale or otherwise dispose of or distribute, establish or increase a put equivalent position or liquidation with respect to or decrease of a call equivalent position within the meaning of Section 16 of the Exchange Act with respect to, any security, (b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (c) publicly announce any intention to effect any transaction specified in clause (a) or (b) (each, a “Transfer”) any (i) shares of Domesticated Parent Common Stock or any other shares of the Company’s capital stock, (ii) options or warrants to purchase any shares of Domesticated Parent Common Stock or any other shares of the Company’s capital stock or (iii) securities convertible into, exercisable for, exchangeable for or that represent the right to receive shares of Domesticated Parent Common Stock or any other shares of the Company’s capital stock, in each case, whether now owned or hereinafter acquired, that are owned directly by such Existing Holder or New Holder (including securities held as a custodian) or with respect to which such Existing Holder or New Holder has beneficial ownership within the rules and regulations of the Commission (collectively, the “Restricted Shares”). The foregoing restriction is expressly agreed to preclude each Existing Holder and New Holder from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Restricted Shares even if such Restricted Shares would be disposed of by someone other than such Existing Holder or each New Holder, as applicable. Such prohibited hedging or other transactions include any short sale or any purchase, sale or grant of any right (including any put or call option) with respect to any of the Restricted Shares of the applicable Existing Holder or New Holder or with respect to any security that includes, relates to, or derives any significant part of its value from such Restricted Shares; provided, however, that the foregoing restrictions are not intended to cover liens established in the ordinary course in favor of a broker-dealer over property held in an account with such broker-dealer generally.

3.6.2 Notwithstanding the provisions set forth in subsection 3.6.1:

(a) with respect to any Existing Holder, Transfers of Registrable Securities are permitted during the applicable Lock-Up Period:

provided that in the case of any Transfer pursuant to clauses (a)(i), (ii), (iii), (iv), (v), (vi) and (vii) such Transfer shall not involve a disposition for value; provided, further that in the case of any Transfer pursuant to clauses (a)(i), (ii), (iii), (iv) and (vi), each donee, devisee, transferee or distributee enters into a written agreement with the Company agreeing to be bound to the restrictions set forth herein; and provided, further, that in the case of any permitted Transfer no public filing, report or announcement shall be voluntarily made and if any filing under Section 16(a) of the Exchange Act, or other public filing, report or announcement reporting a reduction in beneficial ownership of shares of Domesticated Parent Common Stock in connection with such Transfer shall be legally required during the applicable Lock-Up Period, such filing, report or announcement shall clearly indicate in the footnotes thereto the nature and conditions of such transfer.

(b) with respect to any New Holder, Transfers of Domesticated Parent Common Stock are permitted during the applicable Lock-Up Period:

(i) to any New Holder’s Affiliate;

(ii) in the case of an individual, by gift to a member of one of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family, an affiliate of such person or to a charitable organization;

(vii) to the Company from an employee of the Company upon death, disability or termination of employment, in each case, of such employee;

(viii) to the Company in connection with the vesting, settlement, or exercise of restricted stock units, performance stock units, options, warrants or other rights to purchase shares of Domesticated Parent Common Stock (including, in each case, by way of “net” or “cashless” exercise), including for the payment of exercise price and tax and remittance payments due as a result of the vesting, settlement, or exercise of such restricted stock units, performance stock units, options, warrants or rights; provided that any such restricted stock units, performance stock units, options, warrants or other rights are held by a New Holder pursuant to an agreement or equity awards granted under a stock incentive plan or other equity award plan;

(ix) as part of a sale of Domesticated Parent Common Stock to cover the payment of any exercise price and tax and remittance payment due as the result of the vesting, settlement, or exercise of restricted stock units, performance stock units, options, warrants or other rights to purchase shares of Domesticated Parent Common Stock; provided that any such restricted stock units, performance stock units, options, warrants or other rights are held by a New Holder pursuant to an agreement or equity awards granted under a stock incentive plan or other equity award plan;

(c) the Board may, in its sole discretion, determine to waive, amend, or repeal the lock-up obligations set forth in subsection 3.6.1; provided that any such waiver, amendment or repeal shall require, in addition to any other vote of the members of the Board required to take such action pursuant to these bylaws or applicable law, the affirmative vote of the Sponsor Director.

3.6.3 Each Existing Holder and each New Holder hereby represents and warrants that it now has and, except as contemplated by Section 3.6.2 for the duration of the applicable Lock-Up Period, will have good and marketable title to its Restricted Shares, free and clear of all liens, encumbrances, and claims that could impact the ability of such Existing Holder or New Holder, as applicable, to comply with the foregoing restrictions. Each Existing Holder and each New Holder agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent against the Transfer of any Restricted Shares during the applicable Lock-Up Period, except in compliance with the foregoing restrictions.

ARTICLE 4

INDEMNIFICATION AND CONTRIBUTION

4.1 Indemnification.

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact

required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder.

4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus (the “Holder Information”) and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained or incorporated by reference in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in (or not contained in, in the case of an omission) any information or affidavit so furnished in writing by or on behalf of such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

4.1.3 Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement, which (a) cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement), (b) includes a statement or admission of fault and culpability on the part of such indemnified party or (c) does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the Transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

4.1.5 If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question,

including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this subsection 4.1.5 shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this subsection 4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this subsection 4.1.5 from any person who was not guilty of such fraudulent misrepresentation.

ARTICLE 5

STOCKHOLDER RIGHTS

5.1 Stockholder Rights. At any time and from time to time on or after the date hereof and until the later of (i) such time as the Sponsor ceases to beneficially own at least ten percent (10%) of the Company’s outstanding voting stock and (ii) subject to compliance with the rules of The Nasdaq Stock Market, the third anniversary of the date of this Merger Agreement:

5.1.1 The Sponsor shall have the right, but not the obligation, to designate one individual to be appointed or nominated, as the case may be, for election to the Board (including any successor, each, a “Nominee”) as a Class III director by giving written notice to the Company on or before the time such information is reasonably requested by the Board or the Nominating Committee of the Board, as applicable, for inclusion in a proxy statement for a meeting of stockholders provided to the Sponsor. Any Nominee shall be subject to the consent of the Board (not to be unreasonably withheld, conditioned or delayed); provided, that the Board’s consent shall not be required if such Nominee is Josh Tamaroff, Garrett Lustig, or any individual who is a director of the Company as of the date of the Merger Agreement.

5.1.2 The Company will, as promptly as practicable, use its commercially reasonable efforts to ensure that there is one Sponsor Director serving on the Board at all times that the Sponsor shall be entitled to nominate a Director.

5.1.3 The Company shall, to the fullest extent permitted by applicable law, use its commercially reasonable efforts to ensure that: (i) the Nominee is included in the Board’s slate of nominees to the stockholders of the Company for each election of the applicable class of Directors; and (ii) the Nominee is included in the proxy statement prepared by management of the Company in connection with soliciting proxies for such meeting of the stockholders of the Company called with respect to the election of members of the Board, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company or the Board with respect to the election of members of the Board.

5.1.4 If a vacancy occurs because of the death, disability, disqualification, resignation, or removal (or for any other reason) of a Sponsor Director, the Sponsor shall be entitled to designate such person’s successor, and the Company will promptly following such designation use its commercially reasonable efforts to ensure that such vacancy shall be filled with such successor Nominee.

5.1.5 If a Nominee is not elected for any reason, the Sponsor shall be entitled to designate promptly another Nominee and the Company will use its commercially reasonable efforts to ensure that the director position for which such Nominee was nominated shall not be filled pending such designation or that the size of the Board shall be increased by one and such vacancy shall be filled with such successor Nominee as promptly as practicable following such designation.

5.1.6 Promptly following the request of any Sponsor Director, the Company shall enter into an indemnification agreement with such Sponsor Director, in the form entered into with the other members of the Board. The Company shall pay the reasonable, documented out-of-pocket expenses incurred by the Sponsor Director in connection with his or her services provided to or on behalf of the Company, including attending meetings or events attended explicitly on behalf of the Company at the Company’s request.

5.1.7 Any Nominee will be subject to the Company’s customary due diligence process, including its review of a completed questionnaire and a background check. Based on the foregoing, the Company may object to any Nominee provided (a) it does so in good faith, and (b) such objection is based upon any of the following: (i) such Nominee was convicted in a criminal proceeding or is a named subject of a pending criminal proceeding (excluding traffic violations and other minor offenses), (ii) such Nominee was the subject of any order, judgment or decree not subsequently reversed, suspended or vacated of any court of competent jurisdiction, permanently or temporarily enjoining such proposed director from, or otherwise limiting, the following activities: (A) engaging in any type of business practice, or (B) engaging in any activity in connection with the purchase or sale of any security or in connection with any violation of federal or state securities laws, (iii) such Nominee was the subject of any order, judgment or decree, not subsequently reversed, suspended or vacated, of any federal or state authority barring, suspending or otherwise limiting the right of such person to engage in any activity described in clause (ii)(B), or to be associated with persons engaged in such activity, (iv) such proposed director was found by a court of competent jurisdiction in a civil action or by the Commission to have violated any federal or state securities law, and the judgment in such civil action or finding by the Commission has not been subsequently reversed, suspended or vacated, or (v) such proposed director was the subject of, or a party to any federal or state judicial or administrative order, judgment, decree or finding, not subsequently reversed, suspended or vacated, relating to a violation of any federal or state securities laws or regulations. In the event the Board reasonably finds the Nominee to be unsuitable based upon one or more of the foregoing clauses (i) through (v) and reasonably objects to the identified director, the Sponsor shall be entitled to propose a different nominee to the Board within thirty (30) calendar days of the Company’s notice to the Sponsor of its objection to the Nominee and such replacement Nominee shall be subject to the review process outlined above.

6.8 Amendments and Modifications. Upon the written consent of the Company and the Holders of at least a majority-in-interest of the Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, solely in its capacity as a holder of the shares of the Company, in a manner that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so affected; and provided, further, that the Company may waive the lockup restrictions as set forth in Section 3.6.2. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

Any party to this Agreement may waive any right, breach or default which such party has the right to waive, provided that such waiver will not be effective against the waiving party unless it is in writing, is signed by such party, and specifically refers to this Agreement. Waivers may be made in advance or after the right waived has arisen or the breach or default waived has occurred. Any waiver may be conditional. No waiver of any breach of any agreement or provision herein contained shall be deemed a waiver of any preceding or succeeding breach thereof nor of any other agreement or provision herein contained. No waiver or extension of time for performance of any obligations or acts shall be deemed a waiver or extension of the time for performance of any other obligations or acts.

6.11 Remedies Cumulative. In the event that the Company fails to observe or perform any covenant or agreement to be observed or performed under this Agreement, the Holders may proceed to protect and enforce its rights by suit in equity or action at law, whether for specific performance of any term contained in this Agreement or for an injunction against the breach of any such term or in aid of the exercise of any power granted in this Agreement or to enforce any other legal or equitable right, or to take any one or more of such actions, without being required to post a bond. None of the rights, powers or remedies conferred under this Agreement shall be mutually exclusive, and each such right, power or remedy shall be cumulative and in addition to any other right, power or remedy, whether conferred by this Agreement or now or hereafter available at law, in equity, by statute or otherwise.

6.12 Other Registration Rights. The Company represents and warrants that no person, other than a Holder of Registrable Securities, has any right to require the Company to register any securities of the Company for sale or to include such securities of the Company in any Registration filed by the Company for the sale of securities for its own account or for the account of any other person. Further, the Company represents and warrants that this Agreement supersedes any other registration rights agreement or agreement with similar terms and conditions and in the event of a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.

(c) Any certificates or book entries representing the Earnout Founder Shares shall bear a legend referencing that they are subject to forfeiture pursuant to the provisions of this Letter Agreement, and any transfer agent for the shares of Domesticated Parent Common Stock will be given appropriate stop transfer orders that will be applicable until the Earnout Founder Shares are vested; provided, however, that upon the vesting of any Earnout Founder Shares in accordance with the terms herein, Parent shall immediately cause the removal of such legend and direct such transfer agent that such stop transfer orders are no longer applicable. Holders of the Earnout Founder Shares shall be entitled to vote such Earnout Founder Shares and receive dividends and other distributions in respect thereof prior to the vesting of such Earnout Founder Shares in accordance with the terms herein; provided, that any such dividends and other distributions in respect of the Earnout Founder Shares that are subject to vesting pursuant to the terms herein shall be set aside by Parent and shall only be paid to the holder of such Earnout Founder Shares upon the vesting thereof.

(d) The Earnout Founder Shares shall immediately become fully vested and no longer subject to forfeiture upon the occurrence of the applicable Triggering Event during the Earnout Period.

(e) If Parent at any time combines or subdivides the Domesticated Parent Common Stock (by any stock split, stock dividend, recapitalization, reorganization, merger, amendment of the applicable Governing Documents, scheme, arrangement or otherwise or extraordinary dividend resulting from an asset sale or leveraged recapitalization), the number of Earnout Founder Shares and the share prices set forth in the definition of “Triggering Events” shall be equitably adjusted by Parent in good faith to take into account such stock split, stock dividend, recapitalization, reorganization, merger, amendment of the applicable Governing Documents, scheme, arrangement or extraordinary dividend or other applicable transaction.

ARTICLE III

PURPOSE

The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware (the “DGCL”) as it now exists or may hereafter be amended and supplemented.

ARTICLE IV

CAPITAL STOCK

The Corporation is authorized to issue two classes of stock to be designated, respectively, “Common Stock,” and “Preferred Stock.” The total number of shares of capital stock which the Corporation shall have authority to issue is 1,100,000,000. The total number of shares of Common Stock that the Corporation is authorized to issue is 1,000,000,000, having a par value of $0.0001 per share, and the total number of shares of Preferred Stock that the Corporation is authorized to issue is 100,000,000, having a par value of $0.0001 per share.

Upon the filing and effectiveness of this Certificate with the Secretary of State of the State of Delaware (the “Effective Time”), each Class A ordinary fully paid share, par value $0.0001 per share, and each Class B ordinary fully paid share, par value $0.0001 per share, of Avista Public Acquisition Corp. II, a Cayman Islands exempted company and the Corporation’s predecessor prior to its domestication as a Delaware corporation, issued and outstanding or held in treasury immediately prior to the Effective Time (“Old Common Stock”) and without any action on the part of the holder thereof, shall be reclassified as and converted into one share of Common Stock, with a par value of $0.0001 per share. Any stock certificate or book entry representing shares of Old Common Stock shall thereafter represent a number of whole shares of Common Stock into which such shares of Old Common Stock shall have been reclassified.

The designations and the powers, privileges and rights, and the qualifications, limitations or restrictions thereof in respect of each class of capital stock of the Corporation are as follows:

A. COMMON STOCK.

1. General. The voting, dividend, liquidation, and other rights and powers of the Common Stock are subject to and qualified by the rights, powers and preferences of any series of Preferred Stock as may be designated by the Board of Directors of the Corporation (the “Board of Directors”) and outstanding from time to time.

2. Voting. Except as otherwise provided herein or expressly required by law, each holder of Common Stock, as such, shall be entitled to vote on each matter submitted to a vote of stockholders and shall be entitled to one (1) vote for each share of Common Stock held of record by such holder as of the record date for determining stockholders entitled to vote on such matter. Except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate (including any Certificate of Designation (as defined below)) that relates solely to the terms of any outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Certificate (including any Certificate of Designation) or pursuant to the DGCL.

Subject to the rights of any holders of any outstanding series of Preferred Stock, the number of authorized shares of Common Stock or Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding), in each case by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the DGCL.

3. Dividends. Subject to applicable law and the rights and preferences of any holders of any outstanding series of Preferred Stock, the holders of Common Stock, as such, shall be entitled to the payment of dividends on the Common Stock when, as and if declared by the Board of Directors in accordance with applicable law.

4. Liquidation. Subject to the rights and preferences of any holders of any shares of any outstanding series of Preferred Stock, in the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation, and after payment or provision for payment of the debts and other liabilities of the Corporation, if any, the funds and assets of the Corporation that may be legally distributed to the Corporation’s stockholders shall be distributed among the holders of the then outstanding Common Stock pro rata in accordance with the number of shares of Common Stock held by each such holder.

B. PREFERRED STOCK

Shares of Preferred Stock may be issued from time to time in one or more series, each of such series to have such terms as stated or expressed herein and in the resolution or resolutions providing for the creation and issuance of such series adopted by the Board of Directors hereinafter provided.

Authority is hereby expressly granted to the Board of Directors from time to time to issue the Preferred Stock in one or more series, and in connection with the creation of any such series, by adopting a resolution or resolutions providing for the issuance of the shares thereof and by filing a certificate of designation relating thereto in accordance with the DGCL (a “Certificate of Designation”), to determine and fix the number of shares of such series and such voting powers, full or limited, or no voting powers, and such designations, preferences and relative participating, optional or other special rights, and qualifications, limitations or restrictions thereof, including without limitation thereof, dividend rights, conversion rights, redemption privileges and liquidation preferences, and to increase or decrease (but not below the number of shares of such series then outstanding) the number of shares of any series as shall be stated and expressed in such resolutions, all to the fullest extent now or hereafter permitted by the DGCL. Without limiting the generality of the foregoing, the resolution or resolutions providing for the creation and issuance of any series of Preferred Stock may provide that such series shall be superior or rank equally or be junior to any other series of Preferred Stock to the extent permitted by law and this Certificate (including any Certificate of Designation). Except as otherwise required by law, holders of any series of Preferred Stock shall be entitled only to such voting rights, if any, as shall expressly be granted thereto by this Certificate (including any Certificate of Designation).

The number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the DGCL.

ARTICLE V

BOARD OF DIRECTORS

For the management of the business and for the conduct of the affairs of the Corporation it is further provided that:

A. Other than those directors, if any, elected by the holders of any series of Preferred Stock, the directors of the Corporation shall be classified with respect to the time for which they severally hold office into three (3) classes, as nearly equal in number as possible, designated as Class I, Class II and Class III. Except for the terms of such additional directors, if any, as elected by the holders of any series of Preferred Stock, each director shall serve for a term ending on the date of the third (3rd) annual meeting of stockholders following the annual meeting at which the director was elected. The initial Class I directors shall serve for a term expiring at the first (1st) annual meeting of the stockholders following the date of this Certificate; the initial Class II directors shall serve for a term expiring at the second (2nd) annual meeting of the stockholders following the date of this Certificate; and the initial Class III directors shall serve for a term expiring at the third (3rd) annual meeting of the stockholders following the date of this Certificate. At each annual meeting of the stockholders of the Corporation beginning with the first annual meeting of the stockholders following the date of this Certificate, the successors of the class of directors whose term expires at that meeting shall be elected to hold office for a term expiring at the annual meeting of the stockholders held in the third year following the year of their election. If the number of directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain the number of directors in each class as nearly equal as possible, and any additional director of any class elected to fill a vacancy resulting from an increase in such class or from the removal from office, death, resignation, retirement, disqualification, removal of a director or other cause shall hold office for a term that shall coincide with the remaining term of that class. In no event, will a decrease in the number of directors have the effect of removing or shortening the term of any incumbent director. The Board of Directors is authorized to assign members of the Board of Directors already in office to Class I, Class II and Class III.

B. Except as otherwise expressly provided by the DGCL or this Certificate, the business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. Except as otherwise provided for or fixed pursuant to Part E of this Article V relating to the rights of the holders of any series of Preferred Stock to elect additional directors, the number of directors which shall constitute the whole Board of Directors shall be fixed exclusively by one or more resolutions adopted from time to time by the Board of Directors.

C. Subject to any special rights of the holders of one or more outstanding series of Preferred Stock to elect directors, the Board of Directors or any individual director may be removed from office at any time, but only for cause and only by the affirmative vote of the holders of at least two-thirds (66 and 2/3%) of the voting power of all of the then outstanding shares of voting stock of the Corporation entitled to vote generally in an election of directors.

D. Subject to any special rights of the holders of one or more outstanding series of Preferred Stock to elect directors, except as otherwise provided by law, any vacancies on the Board of Directors resulting from death, resignation, retirement, disqualification, removal or other causes and any newly created directorships resulting from any increase in the number of directors shall be filled exclusively by the affirmative vote of a majority of the directors then in office, even though less than a quorum, or by a sole remaining director (other than any directors elected by the separate vote of one or more outstanding series of Preferred Stock), and shall not be filled by the stockholders. Any director appointed in accordance with the preceding sentence shall hold office until the expiration of the term of the class to which such director shall have been appointed or until his or her earlier death, resignation, retirement, disqualification, or removal.

ARTICLE XVE. Whenever the holders of any one or more series of Preferred Stock issued by the Corporation shall have the right, voting separately as a series or separately as a class with one or more such other series, to elect directors at an annual or special meeting of stockholders, the election, term of office, removal and other features of such directorships shall be governed by the terms of this Certificate (including any Certificate of Designation). Notwithstanding anything to the contrary in this Article V, the number of directors that may be elected by the holders of any such series of Preferred Stock shall be in addition to the number fixed pursuant to Part B of this Article V, and the total number of directors constituting the whole Board of Directors shall be automatically adjusted accordingly. Except as otherwise provided in the Certificate of Designation(s) in respect of one or more series of Preferred Stock, whenever the holders of any series of Preferred Stock having such right to elect additional directors are divested of such right pursuant to the provisions of such Certificate of Designation(s), the terms of office of all such additional directors elected by the holders of such series of Preferred Stock, or elected to fill any vacancies resulting from the death, resignation, retirement, disqualification or removal of such additional directors, shall forthwith terminate (in which case each such director thereupon shall cease to be qualified as, and shall cease to be, a director) and the total authorized number of directors of the Corporation shall automatically be reduced accordingly.

F. In furtherance and not in limitation of the powers conferred by statute, the Board of Directors is expressly authorized to adopt, amend or repeal the Bylaws of the Corporation (as amended and/or restated from time to time, the “Bylaws”). The stockholders of the Corporation shall also have power to adopt, amend or repeal the Bylaws; provided, however, in addition to any vote of the holders of any class or series of stock of the Corporation required by applicable law or by this Certificate (including any Certificate of Designation in respect of one or more series of Preferred Stock) or the Bylaws of the Corporation, the adoption, amendment or repeal of the Bylaws of the Corporation by the stockholders of the Corporation shall require the affirmative vote of the holders of at least two-thirds (66 and 2/3%) of the voting power of all of the then outstanding shares of voting stock of the Corporation entitled to vote generally in an election of directors, voting together as a single class.

G. The directors of the Corporation need not be elected by written ballot unless the Bylaws so provide.

ARTICLE VI

STOCKHOLDERS

A. Any action required or permitted to be taken by the stockholders of the Corporation may be effected only at a duly called annual or special meeting of stockholders and may not be effected by any consent in writing by such stockholders in lieu of such meeting. Notwithstanding the foregoing, any action required or permitted to be taken by the holders of any series of Preferred Stock, voting separately as a series or separately as a class with one or more other such series, may be taken without a meeting, without prior notice and without a vote, to the extent expressly so provided by the applicable Certificate of Designation relating to such series of Preferred Stock, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding shares of the relevant series of Preferred Stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation in accordance with the applicable provisions of the DGCL.

B. Subject to the special rights of the holders of one or more series of Preferred Stock, special meetings of the stockholders of the Corporation may be called, for any purpose or purposes, at any time only by or at the direction of (i) the Board of Directors, (ii) the Chairperson of the Board of Directors, (iii) the Chief Executive Officer, or (iv) the President, and shall not be called by any other person or persons.

C. Advance notice of stockholder nominations for the election of directors and of other business proposed to be brought by stockholders before any meeting of the stockholders of the Corporation shall be given in the manner provided in the Bylaws of the Corporation.

ARTICLE VII

LIABILITY

No director of the Corporation shall have any personal liability to the Corporation or its stockholders for monetary damages for any breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or hereafter may be amended. Any amendment, repeal or modification of this Article VII, or the adoption of any provision of the Certificate inconsistent with this Article VII, shall not adversely affect any right or protection of a director of the Corporation with respect to any act or omission occurring prior to the time of such amendment, repeal, modification or adoption. If the DGCL is amended after approval by the stockholders of this Article VII to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL as so amended.

ARTICLE VIII

INDEMNIFICATION

The Corporation shall have the power to provide rights to indemnification and advancement of expenses to its current and former officers, directors, employees and agents and to any person who is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise.

ARTICLE IX

FORUM SELECTION

Unless the Corporation consents in writing to the selection of an alternative forum, (a) the Court of Chancery (the “Chancery Court”) of the State of Delaware (or, in the event that the Chancery Court does not have jurisdiction, the federal district court for the District of Delaware or other state courts of the State of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action, suit or proceeding (“Proceeding”) brought on behalf of the Corporation, (ii) any Proceeding asserting a claim of breach of a fiduciary duty owed by any director, officer or stockholder of the Corporation to the Corporation or to the Corporation’s stockholders, (iii) any Proceeding arising pursuant to any provision of the DGCL, this Certificate or the Bylaws (in each case, as may be amended from time to time) or (iv) any Proceeding asserting a claim against the Corporation governed by the internal affairs doctrine; and (b) subject to the preceding provisions of this Article IX, to the extent permitted by applicable law, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. If any action the subject matter of which is within the scope of clause (a) of the immediately preceding sentence is filed in a court other than the courts in the State of Delaware (a “Foreign Action”) in the name of any stockholder, such stockholder shall be deemed to have consented to (x) the personal jurisdiction of the state and federal courts in the State of Delaware in connection with any action brought in any such court to enforce the provisions of clause (a) of the immediately preceding sentence and (y) having service of process made upon such stockholder in any such action by service upon such stockholder’s counsel in the Foreign Action as agent for such stockholder. If any action the subject matter of which is within the scope of clause (b) of this Article IX is filed in a court other than the federal district courts of the United States of America (a “Foreign Securities Act Action”) in the name of any stockholder, such stockholder shall be deemed to have consented to (i) the personal jurisdiction of the federal district courts of the United States of America in connection with any action brought in any such court to enforce clause (b) (a “Securities Act Enforcement Action”), and (ii) having service of process made upon such stockholder in any such Securities Act Enforcement Action by service upon such stockholder’s counsel in the Foreign Securities Act Action as agent for such stockholder.

For the avoidance of doubt, clause (b) of this Article IX is intended to benefit and may be enforced by the Corporation, its officers and directors, the underwriters to any offering giving rise to any Proceeding, and any other professional or entity whose profession gives authority to a statement made by that person or entity and who has prepared or certified any part of the documents underlying the offering.

Any person or entity purchasing or otherwise acquiring any interest in any security of the Corporation shall be deemed to have notice of and consented to this Article IX.

Notwithstanding the foregoing, the provisions of this Article IX shall not apply to suits brought to enforce any liability or duty created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts of the United States have exclusive jurisdiction.

If any provision or provisions of this Article IX shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever, (i) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Article IX (including, without limitation, each portion of any paragraph of this Article IX containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and (ii) the application of such provision to other persons or entities and circumstances shall not in any way be affected or impaired thereby.

ARTICLE X

AMENDMENTS

A.

ARTICLE XX- CORPORATE OFFICES

Section 20.1 Registered Office. The address of the registered office of [OmniAb, Inc.] (the “Corporation”) in the State of Delaware, and the name of its registered agent at such address, shall be as set forth in the Corporation’s certificate of incorporation, as the same may be amended and/or restated from time to time (the “Certificate of Incorporation”).

Section 20.2 Other Offices. The Corporation may have additional offices at any place or places, within or outside the State of Delaware, as the Corporation’s board of directors (the “Board”) may from time to time establish or as the business of the Corporation may require.

ARTICLE XXI- MEETINGS OF STOCKHOLDERS

Section 21.1 Place of Meetings. Meetings of stockholders shall be held at any place, within or outside the State of Delaware, designated by the Board. The Board may, in its sole discretion, determine that a meeting of stockholders shall not be held at any place, but may instead be held solely by means of remote communication as authorized by Section 211(a) of the General Corporation Law of the State of Delaware (the “DGCL”). In the absence of any such designation or determination, stockholders’ meetings shall be held at the Corporation’s principal executive office.

Section 21.2 Annual Meeting.

The Board shall designate the date and time of the annual meeting. At the annual meeting, directors shall be elected and other proper business properly brought before the meeting in accordance with Section 2.4 may be transacted. The Board may postpone, reschedule or cancel any previously scheduled annual meeting of stockholders.

Section 21.3 Special Meeting.

Special meetings of the stockholders may be called only by such persons and only in such manner as set forth in the Certificate of Incorporation.

No business may be transacted at any special meeting of stockholders other than the business specified in the notice of such meeting. The Board may postpone, reschedule or cancel any previously scheduled special meeting of stockholders.

Section 21.4 Notice of Business to be Brought before a Meeting.

(a) At an annual meeting of the stockholders, only such business shall be conducted as shall have been properly brought before the meeting. To be properly brought before an annual meeting, business must be (i) specified in a notice of meeting given by or at the direction of the Board, (ii) if not specified in a notice of meeting, otherwise brought before the meeting by the Board or the Chairperson of the Board or (iii) otherwise properly brought before the meeting by a stockholder present in person who (A) (1) was a record owner of shares of the Corporation both at the time of giving the notice provided for in this Section 2.4 and at the time of the meeting, (2) is entitled to vote at the meeting and (3) has complied with this Section 2.4 in all applicable respects or (B) properly made such proposal in accordance with Rule 14a-8 under the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (as so amended and inclusive of such rules and regulations, the “Exchange Act”). The foregoing clause (iii) shall be the exclusive means for a stockholder to propose business to be brought before an annual meeting of the stockholders. The only matters that may be brought before a special meeting are the matters specified in the notice of meeting given by or at the direction of the person calling the meeting pursuant to Section 2.3, and stockholders shall not be permitted to propose business to be brought before a special meeting of the stockholders. For purposes of this Section 2.4, “present in person” shall mean that the stockholder proposing that the business be brought before the annual meeting of the Corporation, or a qualified representative of such proposing stockholder, appear at such annual meeting in person, or by remote communication, if applicable. A “qualified representative” of such proposing stockholder shall be a duly authorized officer, manager or partner of such stockholder or any other person authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders. Stockholders seeking to nominate persons for election to the Board must comply with Section 2.5, and this Section 2.4 shall not be applicable to nominations except as expressly provided in Section 2.5.

(b) Without qualification, for business to be properly brought before an annual meeting by a stockholder, the stockholder must (i) provide Timely Notice (as defined below) thereof in writing and in proper form to the Secretary of the Corporation and (ii) provide any updates or supplements to such notice at the times and in the forms required by this Section 2.4. To be timely, a stockholder’s notice must be delivered to, or mailed and received at, the principal executive offices of the Corporation not less than ninety (90) days nor more than one hundred twenty (120) days prior to the one-year anniversary of the preceding year’s annual meeting; provided, however, that if no annual meeting was held in the preceding year, to be timely, a stockholder’s notice must be so delivered, or mailed and received, not earlier than the close of business on the one hundred and twentieth (120^th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90^th) day prior to such annual meeting or, if later, the tenth (10^th) day following the day on which public disclosure of the date of such annual meeting was first made by the Corporation; provided, further, that if the date of the annual meeting is more than thirty (30) days before or more than sixty (60) days after such anniversary date, to be timely, a stockholder’s notice must be so delivered, or mailed and received, not later than the ninetieth (90^th) day prior to such annual meeting or, if later, the tenth (10^th) day following the day on which public disclosure of the date of such annual meeting was first made by the Corporation (such notice within such time periods, “Timely Notice”). In no event shall any adjournment or postponement of an annual meeting or the announcement thereof commence a new time period for the giving of Timely Notice as described above.

(c) To be in proper form for purposes of this Section 2.4, a stockholder’s notice to the Secretary of the Corporation shall set forth:

(i) As to each Proposing Person (as defined below), (A) the name and address of such Proposing Person (including, if applicable, the name and address that appear on the Corporation’s books and records); and (B) the class or series and number of shares of the Corporation that are, directly or indirectly, owned of record or beneficially owned (within the meaning of Rule 13d-3 under the Exchange Act) by such Proposing Person, except that such Proposing Person shall in all events be deemed to beneficially own any shares of any class or series of the Corporation as to which such Proposing Person has a right to acquire beneficial ownership at any time in the future (the disclosures to be made pursuant to the foregoing clauses (A) and (B) are referred to as “Stockholder Information”);

(ii) As to each Proposing Person, (A) the full notional amount of any securities that, directly or indirectly, underlie any “derivative security” (as such term is defined in Rule 16a-1(c) under the Exchange Act) that constitutes a “call equivalent position” (as such term is defined in Rule 16a-1(b) under the Exchange Act) (“Synthetic Equity Position”) and that is, directly or indirectly, held or maintained by such Proposing Person with respect to any shares of any class or series of shares of the Corporation; provided that, for the purposes of the definition of “Synthetic Equity Position,” the term “derivative security” shall also include any security or instrument that would not otherwise constitute a “derivative security” as a result of any feature that would make any conversion, exercise or similar right or privilege of such security or instrument becoming determinable only at some future date or upon the happening of a future occurrence, in which case the determination of the amount of securities into which such security or instrument would be convertible or exercisable shall be made assuming that such security or instrument is immediately convertible or exercisable at the time of such determination; and, provided, further, that any Proposing Person satisfying the requirements of Rule 13d-1(b)(1) under the Exchange Act (other than a Proposing Person that so satisfies Rule 13d-1(b)(1) under the Exchange Act solely by reason of Rule 13d-1(b)(1)(ii)(E)) shall not be deemed to hold or maintain the notional amount of any securities that underlie a Synthetic Equity Position held by such Proposing Person as a hedge with respect to a bona fide derivatives trade or position of such Proposing Person arising in the ordinary course of such Proposing Person’s business as a derivatives dealer, (B) any rights to dividends on the shares of any class or series of shares of the Corporation owned beneficially by such Proposing Person that are separated or separable from the underlying shares of the Corporation, (C) any material pending or threatened legal proceeding in which such Proposing Person is a party or material participant involving the Corporation or any of its officers or directors, or any affiliate of the Corporation, (D) any other

material relationship between such Proposing Person, on the one hand, and the Corporation or any affiliate of the Corporation, on the other hand, (E) any direct or indirect material interest in any material contract or agreement of such Proposing Person with the Corporation or any affiliate of the Corporation (including, in any such case, any employment agreement, collective bargaining agreement or consulting agreement), (F) a representation that such Proposing Person intends or is part of a group that intends to deliver a proxy statement or form of proxy to holders of at least the percentage of the Corporation’s outstanding capital stock required to approve or adopt the proposal or otherwise solicit proxies from stockholders in support of such proposal and (G) any other information relating to such Proposing Person that would be required to be disclosed in a proxy statement or other filing required to be made in connection with solicitations of proxies or consents by such Proposing Person in support of the business proposed to be brought before the meeting pursuant to Section 14(a) of the Exchange Act (the disclosures to be made pursuant to the foregoing clauses (A) through (G) are referred to as “Disclosable Interests”); provided, however, that Disclosable Interests shall not include any such disclosures with respect to the ordinary course business activities of any broker, dealer, commercial bank, trust company or other nominee who is a Proposing Person solely as a result of being the stockholder directed to prepare and submit the notice required by these bylaws on behalf of a beneficial owner; and

(iii) As to each item of business that the stockholder proposes to bring before the annual meeting, (A) a brief description of the business desired to be brought before the annual meeting, the reasons for conducting such business at the annual meeting and any material interest in such business of each Proposing Person, (B) the text of the proposal or business (including the text of any resolutions proposed for consideration and in the event that such business includes a proposal to amend the bylaws, the language of the proposed amendment), (C) a reasonably detailed description of all agreements, arrangements and understandings (x) between or among any of the Proposing Persons or (y) between or among any Proposing Person and any other person or entity (including their names) in connection with the proposal of such business by such stockholder, and (D) any other information relating to such item of business that would be required to be disclosed in a proxy statement or other filing required to be made in connection with solicitations of proxies in support of the business proposed to be brought before the meeting pursuant to Section 14(a) of the Exchange Act; provided, however, that the disclosures required by this Section 2.4(c)(iii) shall not include any disclosures with respect to any broker, dealer, commercial bank, trust company or other nominee who is a Proposing Person solely as a result of being the stockholder directed to prepare and submit the notice required by these bylaws on behalf of a beneficial owner.

For purposes of this Section 2.4, the term “Proposing Person” shall mean (i) the stockholder providing the notice of business proposed to be brought before an annual meeting, (ii) the beneficial owner or beneficial owners, if different, on whose behalf the notice of the business proposed to be brought before the annual meeting is made, and (iii) any participant (as defined in paragraphs (a)(ii)-(vi) of Instruction 3 to Item 4 of Schedule 14A) with such stockholder in such solicitation.

(d) A Proposing Person shall update and supplement its notice to the Corporation of its intent to propose business at an annual meeting, if necessary, so that the information provided or required to be provided in such notice pursuant to this Section 2.4 shall be true and correct as of the record date for stockholders entitled to vote at the meeting and as of the date that is ten (10) business days prior to the meeting or any adjournment or postponement thereof, and such update and supplement shall be delivered to, or mailed and received by, the Secretary of the Corporation at the principal executive offices of the Corporation not later than five (5) business days after the record date for stockholders entitled to vote at the meeting (in the case of the update and supplement required to be made as of such record date), and not later than eight (8) business days prior to the date for the meeting or, if practicable, any adjournment or postponement thereof (and, if not practicable, on the first practicable date prior to the date to which the meeting has been adjourned or postponed) (in the case of the update and supplement required to be made as of ten (10) business days prior to the meeting or any adjournment or postponement thereof). For the avoidance of doubt, the obligation to update and supplement as set forth in this paragraph or any other Section of these bylaws shall not limit the Corporation’s rights with respect to any deficiencies in any notice provided by a stockholder, extend any applicable deadlines hereunder or enable or be deemed to permit a stockholder who has previously submitted notice hereunder to amend or update any proposal or to submit any new proposal, including by changing or adding matters, business or resolutions proposed to be brought before a meeting of the stockholders.

(e) Notwithstanding anything in these bylaws to the contrary, no business shall be conducted at an annual meeting that is not properly brought before the meeting in accordance with this Section 2.4. The presiding officer of the meeting shall, if the facts warrant, determine that the business was not properly brought before the meeting in accordance with this Section 2.4, and if he or she should so determine, he or she shall so declare to the meeting and any such business not properly brought before the meeting shall not be transacted.

(f) This Section 2.4 is expressly intended to apply to any business proposed to be brought before an annual meeting of stockholders other than any proposal made in accordance with Rule 14a-8 under the Exchange Act and included in the Corporation’s proxy statement. In addition to the requirements of this Section 2.4 with respect to any business proposed to be brought before an annual meeting, each Proposing Person shall comply with all applicable requirements of the Exchange Act with respect to any such business. Nothing in this Section 2.4 shall be deemed to affect the rights of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act.

(g) For purposes of these bylaws, “public disclosure” shall mean disclosure in a press release reported by a national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Sections 13, 14 or 15(d) of the Exchange Act.

Section 21.5 Notice of Nominations for Election to the Board.

(a) Subject in all respects to the provisions of the Certificate of Incorporation, nominations of any person for election to the Board at an annual meeting or at a special meeting (but only if the election of directors is a matter specified in the notice of meeting given by or at the direction of the person calling such special meeting) may be made at such meeting only (i) by or at the direction of the Board, including by any committee or persons authorized to do so by the Board or these bylaws, or (ii) by a stockholder present in person (A) who was a record owner of shares of the Corporation both at the time of giving the notice provided for in this Section 2.5 and at the time of the meeting, (B) is entitled to vote at the meeting, and (C) has complied with this Section 2.5 as to such notice and nomination. For purposes of this Section 2.5, “present in person” shall mean that the stockholder proposing that the business be brought before the meeting of the Corporation, or a qualified representative of such stockholder, appear at such meeting in person, or by remote communication, if applicable. A “qualified representative” of such proposing stockholder shall be a duly authorized officer, manager or partner of such stockholder or any other person authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders. The foregoing clause (iii) shall be the exclusive means for a stockholder to make any nomination of a person or persons for election to the Board at an annual meeting or special meeting other than in accordance with the provisions of the Certificate of Incorporation.

(b) (i) For a stockholder to make any nomination of a person or persons for election to the Board at an annual meeting, the stockholder must (1) provide Timely Notice (as defined in Section 2.4) thereof in writing and in proper form to the Secretary of the Corporation, (2) provide the information, agreements and questionnaires with respect to such stockholder and its candidate for nomination as required to be set forth by this Section 2.5 and (3) provide any updates or supplements to such notice at the times and in the forms required by this Section 2.5.

(ii) If the election of directors is a matter specified in the notice of meeting given by or at the direction of the person calling a special meeting, then for a stockholder to make any nomination of a person or persons for election to the Board at a special meeting, the stockholder must (i) provide Timely Notice thereof in writing and in proper form to the Secretary of the Corporation at the principal executive offices of the Corporation, (ii) provide the information with respect to such stockholder and its candidate for nomination as required by this Section 2.5 and (iii) provide any updates or supplements to such notice at the times and in the forms required by this Section 2.5. To be timely, a stockholder’s notice for nominations to be made at

a special meeting must be delivered to, or mailed and received at, the principal executive offices of the Corporation not earlier than the one hundred twentieth (120^th) day prior to such special meeting and not later than the ninetieth (90^th) day prior to such special meeting or, if later, the tenth (10^th) day following the day on which public disclosure (as defined in Section 2.4) of the date of such special meeting was first made.

(iii) In no event shall any adjournment or postponement of an annual meeting or special meeting or the announcement thereof commence a new time period for the giving of a stockholder’s notice as described above.

(iv) In no event may a Nominating Person provide Timely Notice with respect to a greater number of director candidates than are subject to election by stockholders at the applicable meeting. If the Corporation shall, subsequent to such notice, increase the number of directors subject to election at the meeting, such notice as to any additional nominees shall be due on the later of (i) the conclusion of the time period for Timely Notice, (ii) the date set forth in Section 2.5(b)(ii) or (iii) the tenth day following the date of public disclosure (as defined in Section 2.4) of such increase.

(c) To be in proper form for purposes of this Section 2.5, a stockholder’s notice to the Secretary of the Corporation shall set forth:

(i) As to each Nominating Person (as defined below), the Stockholder Information (as defined in Section 2.4(c)(i) of these bylaws), except that for purposes of this Section 2.5, the term “Nominating Person” shall be substituted for the term “Proposing Person” in all places it appears in Section 2.4(c)(i));

(ii) As to each Nominating Person, any Disclosable Interests (as defined in Section 2.4(c)(ii), except that for purposes of this Section 2.5, the term “Nominating Person” shall be substituted for the term “Proposing Person” in all places it appears in Section 2.4(c)(ii) and the disclosure with respect to the business to be brought before the meeting in Section 2.4(c)(ii) shall be made with respect to the election of directors at the meeting); and

(iii) As to each candidate whom a Nominating Person proposes to nominate for election as a director, (A) all information with respect to such candidate for nomination that would be required to be set forth in a stockholder’s notice pursuant to this Section 2.5 if such candidate for nomination were a Nominating Person, (B) all information relating to such candidate for nomination that is required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors in a contested election pursuant to Section 14(a) under the Exchange Act (including such candidate’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected), (C) a description of any direct or indirect material interest in any material contract or agreement between or among any Nominating Person, on the one hand, and each candidate for nomination or

his or her respective associates or any other participants in such solicitation, on the other hand, including, without limitation, all information that would be required to be disclosed pursuant to Item 404 under Regulation S-K if such Nominating Person were the “registrant” for purposes of such rule and the candidate for nomination were a director or executive officer of such registrant and (D) a completed and signed questionnaire, representation and agreement as provided in Section 2.5(f).

For purposes of this Section 2.5, the term “Nominating Person” shall mean (i) the stockholder providing the notice of the nomination proposed to be made at the meeting, (ii) the beneficial owner or beneficial owners, if different, on whose behalf the notice of the nomination proposed to be made at the meeting is made, and (iii) any other participant (as defined in paragraphs (a)(ii)-(vi) of Instruction 3 to Item 4 of Schedule 14A) in such solicitation.

(d) A stockholder providing notice of any nomination proposed to be made at a meeting shall further update and supplement such notice, if necessary, so that the information provided or required to be provided in such notice pursuant to this Section 2.5 shall be true and correct as of the record date for stockholders entitled to vote at the meeting and as of the date that is ten (10) business days prior to the meeting or any adjournment or postponement thereof, and such update and supplement shall be delivered to, or mailed and received by, the Secretary of the Corporation at the principal executive offices of the Corporation not later than five (5) business days after the record date for stockholders entitled to vote at the meeting (in the case of the update and supplement required to be made as of such record date), and not later than eight (8) business days prior to the date for the meeting or, if practicable, any adjournment or postponement thereof (and, if not practicable, on the first practicable date prior to the date to which the meeting has been adjourned or postponed) (in the case of the update and supplement required to be made as of ten (10) business days prior to the meeting or any adjournment or postponement thereof). For the avoidance of doubt, the obligation to update and supplement as set forth in this paragraph or any other Section of these bylaws shall not limit the Corporation’s rights with respect to any deficiencies in any notice provided by a stockholder, extend any applicable deadlines hereunder or enable or be deemed to permit a stockholder who has previously submitted notice hereunder to amend or update any nomination or to submit any new nomination.

(e) In addition to the requirements of this Section 2.5 with respect to any nomination proposed to be made at a meeting, each Nominating Person shall comply with all applicable requirements of the Exchange Act with respect to any such nominations.

(f) To be eligible to be a candidate for election as a director of the Corporation at an annual or special meeting, a candidate must be nominated in the manner prescribed in Section 2.5 and the candidate for nomination, whether nominated by the Board or by a stockholder of record, must have previously delivered (in accordance with the time period prescribed for delivery in a notice to such candidate given by or on behalf of the Board), to the Secretary of the Corporation at the principal executive offices of the Corporation, (i) a completed written questionnaire (in a form provided by the Corporation) with respect to the background,

qualifications, stock ownership and independence of such proposed nominee and (ii) a written representation and agreement (in form provided by the Corporation) that such candidate for nomination (A) is not and, if elected as a director during his or her term of office, will not become a party to (1) any agreement, arrangement or understanding with, and has not given and will not give any commitment or assurance to, any person or entity as to how such proposed nominee, if elected as a director of the Corporation, will act or vote on any issue or question (a “Voting Commitment”) or (2) any Voting Commitment that could limit or interfere with such proposed nominee’s ability to comply, if elected as a director of the Corporation, with such proposed nominee’s fiduciary duties under applicable law, (B) is not, and will not become a party to, any agreement, arrangement or understanding with any person or entity other than the Corporation with respect to any direct or indirect compensation or reimbursement for service as a director that has not been disclosed to the Corporation and (C) if elected as a director of the Corporation, will comply with all applicable corporate governance, conflict of interest, confidentiality, stock ownership and trading and other policies and guidelines of the Corporation applicable to directors and in effect during such person’s term in office as a director (and, if requested by any candidate for nomination, the Secretary of the Corporation shall provide to such candidate for nomination all such policies and guidelines then in effect).

(g) The Board may also require any proposed candidate for nomination as a Director to furnish such other information as may reasonably be requested by the Board in writing prior to the meeting of stockholders at which such candidate’s nomination is to be acted upon in order for the Board to determine the eligibility of such candidate for nomination to be an independent director of the Corporation in accordance with the Corporation’s corporate governance guidelines.

(h) A candidate for nomination as a director shall further update and supplement the materials delivered pursuant to this Section 2.5, if necessary, so that the information provided or required to be provided pursuant to this Section 2.5 shall be true and correct as of the record date for stockholders entitled to vote at the meeting and as of the date that is ten (10) business days prior to the meeting or any adjournment or postponement thereof, and such update and supplement shall be delivered to, or mailed and received by, the Secretary of the Corporation at the principal executive offices of the Corporation (or any other office specified by the Corporation in any public announcement) not later than five (5) business days after the record date for stockholders entitled to vote at the meeting (in the case of the update and supplement required to be made as of such record date), and not later than eight (8) business days prior to the date for the meeting or, if practicable, any adjournment or postponement thereof (and, if not practicable, on the first practicable date prior to the date to which the meeting has been adjourned or postponed) (in the case of the update and supplement required to be made as of ten (10) business days prior to the meeting or any adjournment or postponement thereof). For the avoidance of doubt, the obligation to update and supplement as set forth in this paragraph or any other Section of these bylaws shall not limit the Corporation’s rights with respect to any deficiencies in any materials delivered pursuant to this Section 2.5 by a candidate for director, extend any applicable deadlines hereunder or enable or be deemed to permit a stockholder who has previously submitted notice hereunder to amend or update any proposal or to submit any new proposal, including by changing or adding nominees, matters, business or resolutions proposed to amend or update any nomination or to submit any new nomination.

(i) No candidate shall be eligible for nomination as a director of the Corporation unless such candidate for nomination and the Nominating Person seeking to place such candidate’s name in nomination has complied with this Section 2.5. The presiding officer at the meeting shall, if the facts warrant, determine that a nomination was not properly made in accordance with Section 2.5, and if he or she should so determine, he or she shall so declare such determination to the meeting, the defective nomination shall be disregarded and any ballots cast for the candidate in question (but in the case of any form of ballot listing other qualified nominees, only the votes cast for the nominee in question) shall be void and of no force or effect.

(j) Notwithstanding anything in these bylaws to the contrary, no candidate for nomination shall be eligible to be seated as a director of the Corporation unless nominated and elected in accordance with Section 2.5.

Section 21.6 Notice of Stockholders’ Meetings.

Unless otherwise provided by law, the Certificate of Incorporation or these bylaws, the notice of any meeting of stockholders shall be sent or otherwise given in accordance with Section 8.1 not less than ten (10) nor more than sixty (60) days before the date of the meeting to each stockholder entitled to vote at such meeting. The notice shall specify the place, if any, date and time of the meeting, the means of remote communication, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called.

Section 21.7 Manner of Giving Notice; Affidavit of Notice.

Notice of any meeting of stockholders shall be deemed given:

(a) if mailed, when deposited in the U.S. mail, postage prepaid, directed to the stockholder at his or her address as it appears on the Corporation’s records; or

(b) if electronically transmitted as provided in the DGCL.

An affidavit of the secretary or an assistant secretary of the Corporation or of the transfer agent or any other agent of the Corporation that the notice has been given by mail or by a form of electronic transmission, as applicable, shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

Section 21.8 Quorum.

Unless otherwise provided by law, the Certificate of Incorporation or these bylaws, the holders of a majority in voting power of the stock issued and outstanding and entitled to vote, present in person, or by remote communication, if applicable, or represented by proxy, shall constitute a quorum for the transaction of business at all meetings of the stockholders. A quorum, once established at a meeting, shall not be broken by the withdrawal of enough votes to leave less than a quorum. If, however, a quorum is not present or represented at any meeting of the stockholders, then either (i) the person presiding over the meeting or (ii) a majority in voting power of the stockholders entitled to vote at the meeting, present in person, or by remote communication, if applicable, or represented by proxy, shall have power to recess the meeting or adjourn the meeting from time to time in the manner provided in Section 2.9 until a quorum is present or represented. At any recessed or adjourned meeting at which a quorum is present or represented, any business may be transacted that might have been transacted at the meeting as originally noticed.

Section 21.9 Adjourned Meeting; Notice.

When a meeting is adjourned to another time or place, unless these bylaws otherwise require, notice need not be given of the adjourned meeting if the time, place, if any, thereof, and the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting are announced at the meeting at which the adjournment is taken. At any adjourned meeting, the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than thirty (30) days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. If after the adjournment a new record date for determination of stockholders entitled to vote is fixed for the adjourned meeting, the Board shall fix as the record date for determining stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote at the adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record entitled to vote at such meeting as of the record date so fixed for notice of such adjourned meeting.

Section 21.10 Conduct of Business.

The date and time of the opening and the closing of the polls for each matter upon which the stockholders will vote at a meeting shall be announced at the meeting by the person presiding over the meeting. The Board may adopt by resolution such rules and regulations for the conduct of the meeting of stockholders as it shall deem appropriate. At every meeting of the stockholders, the Chairperson of the Board, or in his or her absence or inability to act, the Chief Executive Officer, or in his or her absence or inability to act, the officer or director whom the Board shall appoint, shall act as chairperson of, and preside at the meeting. Except to the extent inconsistent with such rules and regulations as adopted by the Board, the person presiding over any meeting of stockholders shall have the right and authority to convene and (for any or no reason) to recess and/or adjourn the meeting, to prescribe such rules, regulations and procedures (which need not be in writing) and to do all such acts as, in the judgment of such presiding person, are appropriate

for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board or prescribed by the person presiding over the meeting, may include, without limitation, the following: (i) the establishment of an agenda or order of business for the meeting; (ii) rules and procedures for maintaining order at the meeting and the safety of those present (including, without limitation, rules and procedures for removal of disruptive persons from the meeting); (iii) limitations on attendance at or participation in the meeting to stockholders entitled to vote at the meeting, their duly authorized and constituted proxies or such other persons as the person presiding over the meeting shall determine; (iv) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (v) limitations on the time allotted to questions or comments by participants. The presiding person at any meeting of stockholders, in addition to making any other determinations that may be appropriate to the conduct of the meeting (including, without limitation, determinations with respect to the administration and/or interpretation of any of the rules, regulations or procedures of the meeting, whether adopted by the Board or prescribed by the person presiding over the meeting), shall, if the facts warrant, determine and declare to the meeting that a matter of business was not properly brought before the meeting and if such presiding person should so determine, such presiding person shall so declare to the meeting and any such matter or business not properly brought before the meeting shall not be transacted or considered. Unless and to the extent determined by the Board or the person presiding over the meeting, meetings of stockholders shall not be required to be held in accordance with the rules of parliamentary procedure.

Section 21.11 Voting.

Except as may be otherwise provided in the Certificate of Incorporation, these bylaws or the DGCL, each stockholder shall be entitled to one (1) vote for each share of capital stock held by such stockholder.

Except as otherwise provided by the Certificate of Incorporation, at all duly called or convened meetings of stockholders at which a quorum is present, for the election of directors, a plurality of the votes cast shall be sufficient to elect a director. Except as otherwise provided by the Certificate of Incorporation, these bylaws, the rules or regulations of any stock exchange applicable to the Corporation, or applicable law or pursuant to any regulation applicable to the Corporation or its securities, each other matter presented to the stockholders at a duly called or convened meeting at which a quorum is present shall be decided by the affirmative vote of the holders of a majority in voting power of the votes cast (excluding abstentions and broker non-votes) on such matter.

Section 21.12 Record Date for Stockholder Meetings and Other Purposes.

In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date shall, unless otherwise required by law, not be more than sixty (60) days nor less than ten (10) days before the date of such meeting. If the Board so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the

Board, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be the close of business on the next day preceding the day on which notice is first given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for determination of stockholders entitled to vote at the adjourned meeting; and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance herewith at the adjourned meeting.

In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment or any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of capital stock, or for the purposes of any other lawful action, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than sixty (60) days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board adopts the resolution relating thereto.

Section 21.13 Proxies.

Each stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for such stockholder by proxy authorized by an instrument in writing or by a transmission permitted by law filed in accordance with the procedure established for the meeting, but no such proxy shall be voted or acted upon after three (3) years from its date, unless the proxy provides for a longer period. The revocability of a proxy that states on its face that it is irrevocable shall be governed by the provisions of Section 212 of the DGCL. A proxy may be in the form of an electronic transmission which sets forth or is submitted with information from which it can be determined that the electronic transmission was authorized by the stockholder.

Any stockholder directly or indirectly soliciting proxies from other stockholders must use a proxy card color other than white, which shall be reserved for the exclusive use by the Board.

Section 21.14 List of Stockholders Entitled to Vote.

The Corporation shall prepare, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting (provided, however, that if the record date for determining the stockholders entitled to vote is less than ten (10) days before the date of the meeting, the list shall reflect the stockholders entitled to vote as of the tenth (10^th) day before the meeting date), arranged in alphabetical order, and showing the

address of each stockholder and the number of shares registered in the name of each stockholder. The Corporation shall not be required to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting for a period of at least ten (10) days prior to the meeting: (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (ii) during ordinary business hours, at the Corporation’s principal executive office. In the event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting. Such list shall presumptively determine the identity of the stockholders entitled to vote at the meeting and the number of shares held by each of them. Except as otherwise provided by law, the stock ledger shall be the only evidence as to who are the stockholders entitled to examine the list of stockholders required by this Section 2.14 or to vote in person or by proxy at any meeting of stockholders.

Section 21.15 Inspectors of Election.

Before any meeting of stockholders, the Corporation shall appoint an inspector or inspectors of election to act at the meeting or its adjournment and make a written report thereof. The Corporation may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If any person appointed as inspector or any alternate fails to appear or fails or refuses to act, then the person presiding over the meeting shall appoint a person to fill that vacancy.

Such inspectors shall:

(a) determine the number of shares outstanding and the voting power of each, the number of shares represented at the meeting and the validity of any proxies and ballots;

(b) count all votes or ballots;

(d) determine and retain for a reasonable period a record of the disposition of any challenges made to any determination by the inspector(s); and

(e) certify its or their determination of the number of shares represented at the meeting and its or their count of all votes and ballots.

Each inspector, before entering upon the discharge of the duties of inspector, shall take and sign an oath faithfully to execute the duties of inspection with strict impartiality and according to the best of such inspector’s ability. Any report or certificate made by the inspectors of election is prima facie evidence of the facts stated therein. The inspectors of election may appoint such persons to assist them in performing their duties as they determine.

Section 21.16 Delivery to the Corporation.

Whenever this Article II requires one or more persons (including a record or beneficial owner of stock) to deliver a document or information to the Corporation or any officer, employee or agent thereof (including any notice, request, questionnaire, revocation, representation or other document or agreement), such document or information shall be in writing exclusively (and not in an electronic transmission) and shall be delivered exclusively by hand (including, without limitation, overnight courier service) or by certified or registered mail, return receipt requested, and the Corporation shall not be required to accept delivery of any document not in such written form or so delivered. For the avoidance of doubt, the Corporation expressly opts out of Section 116 of the DGCL with respect to the delivery of information and documents to the Corporation required by this Article II.

Section 21.17 Stockholder Action by Written Consent Without a Meeting.

Subject to the rights of the holders of any series of Preferred Stock of the Corporation, any action required or permitted to be taken by the stockholders of the Corporation may be effected only at a duly called annual or special meeting of stockholders and may not be effected by any consent in writing by such stockholders in lieu of such meeting. Notwithstanding the foregoing, any action required or permitted to be taken by the holders of any series of preferred stock of the Corporation, voting separately as a series or separately as a class with one or more other such series, may be taken without a meeting, without prior notice and without a vote, to the extent expressly so provided by the applicable certificate of designation relating to such series of preferred stock of the Corporation, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding shares of the relevant series of preferred stock of the Corporation having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation in accordance with the applicable provisions of the DGCL.

At all meetings of the Board, unless otherwise provided by the Certificate of Incorporation, a majority of the total number of directors shall constitute a quorum for the transaction of business.

ARTICLE XXVII- NOTICE

Section 27.1 Delivery of Notice; Notice by Electronic Transmission.

Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the Corporation under any provisions of the DGCL, the Certificate of Incorporation, or these bylaws may be given in writing directed to the stockholder’s mailing address (or by electronic transmission directed to the stockholder’s electronic mail address, as applicable) as it appears on the records of the Corporation and shall be given (1) if mailed, when the notice is deposited in the U.S. mail, postage prepaid, (2) if delivered by courier service, the earlier of when the notice is received or left at such stockholder’s address or (3) if given by electronic mail, when directed to such stockholder’s electronic mail address unless the stockholder has notified the Corporation in writing or by electronic transmission of an objection to receiving notice by electronic mail. A notice by electronic mail must include a prominent legend that the communication is an important notice regarding the Corporation.

Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the Corporation under any provision of the DGCL, the Certificate of Incorporation or these bylaws shall be effective if given by a form of electronic transmission consented to by the stockholder to whom the notice is given. Any such consent shall be revocable by the stockholder by written notice or electronic transmission to the Corporation. Notwithstanding the provisions of this paragraph, the Corporation may give a notice by electronic mail in accordance with the first paragraph of this section without obtaining the consent required by this paragraph.

Any notice given pursuant to the preceding paragraph shall be deemed given:

(a) if by facsimile telecommunication, when directed to a number at which the stockholder has consented to receive notice;

(b) if by a posting on an electronic network together with separate notice to the stockholder of such specific posting, upon the later of (A) such posting and (B) the giving of such separate notice; and

Notwithstanding the foregoing, a notice may not be given by an electronic transmission from and after the time that (1) the Corporation is unable to deliver by such electronic transmission two (2) consecutive notices given by the Corporation and (2) such inability becomes known to the Secretary or an Assistant Secretary of the Corporation or to the transfer agent, or other person responsible for the giving of notice; provided, however, that the inadvertent failure to discover such inability shall not invalidate any meeting or other action.

An affidavit of the Secretary or an Assistant Secretary of the Corporation or of the transfer agent or other agent of the Corporation that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

ARTICLE XXVIII- INDEMNIFICATION

Section 28.1 Indemnification of Directors and Officers.

is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or non-profit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses reasonably incurred by such person in connection with any such Proceeding.

Section 28.3 Prepayment of Expenses.

The Corporation shall to the fullest extent not prohibited by applicable law pay the expenses (including, without limitation, attorneys’ fees) incurred by any covered person, and may also pay the expenses incurred by any employee or agent of the Corporation, in defending any Proceeding in advance of its final disposition; provided, however, that such payment of expenses in advance of the final disposition of the Proceeding shall be made only upon receipt of an undertaking by the person to repay all amounts advanced if it should be ultimately determined that the person is not entitled to be indemnified under this Article IX or otherwise.

Section 28.4 Determination; Claim.

If a claim for indemnification (following the final disposition of such Proceeding) under this Article IX is not paid in full within sixty (60) days, or a claim for advancement of expenses under this Article IX is not paid in full within thirty (30) days, after a written claim therefor has been received by the Corporation the claimant may thereafter (but not before) file suit to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim to the fullest extent permitted by law. In any such action the Corporation shall have the burden of proving that the claimant was not entitled to the requested indemnification or payment of expenses under applicable law.

Section 28.5 Non-Exclusivity of Rights.

The rights conferred on any person by this Article IX shall not be exclusive of any other rights which such person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, these bylaws, agreement, vote of stockholders or disinterested directors or otherwise.

Section 28.7 Other Indemnification.

The Corporation’s obligation, if any, to indemnify or advance expenses to any person who was or is serving at its request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, enterprise or non-profit entity shall be reduced by any amount such person actually collects as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, enterprise or non-profit enterprise.

Section 28.8 Continuation of Indemnification.

The rights to indemnification and to prepayment of expenses provided by, or granted pursuant to, this Article IX shall continue notwithstanding that the person has ceased to be a director or officer of the Corporation and shall inure to the benefit of the estate, heirs, executors, administrators, legatees and distributees of such person.

Section 28.9 Amendment or Repeal; Interpretation.

The provisions of this Article IX shall constitute a contract between the Corporation, on the one hand, and, on the other hand, each individual who serves or has served as a director or officer of the Corporation (whether before or after the adoption of these bylaws), in consideration of such person’s performance of such services, and pursuant to this Article IX the Corporation intends to be legally bound to each such current or former director or officer of the Corporation. With respect to current and former directors and officers of the Corporation, the rights conferred under this Article IX are present contractual rights and such rights are fully vested, and shall be deemed to have vested fully, immediately upon adoption of theses bylaws. With respect to any directors or officers of the Corporation who commence service following adoption of these bylaws, the rights conferred under this provision shall be present contractual rights and such rights shall fully vest, and be deemed to have vested fully, immediately upon such director or officer commencing service as a director or officer of the Corporation. Any repeal or modification of the foregoing provisions of this Article IX shall not adversely affect any right or protection (i) hereunder of any person in respect of any act or omission occurring prior to the time of such repeal or modification or (ii) under any agreement providing for indemnification or advancement of expenses to an officer or director of the Corporation in effect prior to the time of such repeal or modification.

Any reference to an officer of the Corporation in this Article IX shall be deemed to refer exclusively to the Chief Executive Officer, the President and the Secretary of the Corporation, or other officer of the Corporation appointed by (x) the Board pursuant to Article V or (y) an officer to whom the Board has delegated the power to appoint officers pursuant to Article V, and any reference to an officer of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be deemed to refer exclusively to an officer appointed by the board of directors (or equivalent governing body) of such other entity pursuant to the certificate of incorporation and bylaws (or equivalent organizational documents) of such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. The fact that any person who is or was an employee of the Corporation or an employee of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise has been

given or has used the title of “Vice President” or any other title that could be construed to suggest or imply that such person is or may be an officer of the Corporation or of such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall not result in such person being constituted as, or being deemed to be, an officer of the Corporation or of such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise for purposes of this Article IX.

ARTICLE XXIX- AMENDMENTS

The Board is expressly empowered to adopt, amend or repeal the bylaws of the Corporation. The stockholders also shall have power to adopt, amend or repeal the bylaws of the Corporation; provided, however, in addition to any vote of the holders of any class or series of stock of the Corporation required by applicable law or by the Certificate of Incorporation (including any Certificate of Designation in respect of one or more series of Preferred Stock), the adoption, amendment or repeal of the bylaws of the Corporation by the stockholders of the Corporation shall require the affirmative vote of the holders of at least two-thirds (66 and 2/3%) of the voting power of all of the then outstanding shares of voting stock of the Corporation entitled to vote generally in an election of directors, voting together as a single class.

WHEREAS, in connection with the entry into the Merger Agreement, an allocation of up to $100,000,000.00 of committed capital of the Purchaser has been made to subscribe for up to 10,000,000 shares of Domesticated Parent Common Stock and up to 1,666,667 Domesticated Parent Warrants to the extent that the number of shares of Domesticated Parent Common Stock that are redeemed in connection with the consummation of the Transactions would result in the Trust Amount being less than $100,000,000.00, on the terms and conditions set forth herein (the “Backstop Commitment”).

NOW, THEREFORE, in consideration of the premises, representations, warranties and the mutual covenants contained in this Agreement, and for other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

1. Backstop Subscription; Funding Notice.

(a) Backstop Subscription.

To the extent that the Trust Amount is less than $100,000,000 immediately prior to the Effective Time, the Purchaser agrees to purchase (i) a number of shares of Domesticated Parent Common Stock equal to (A) (x) $100,000,000 minus (y) the Trust Amount (such amount, the “Backstop Subscription Amount”), divided by (B) $10.00, rounded down to the nearest whole number (the “Backstop Shares”) and (ii) a number of Domesticated Parent Warrants equal to (I) 1,666,667 multiplied by (II) a number, the numerator of which is the Backstop Subscription Amount and the denominator of which is $100,000,000 (the “Backstop Warrants” and, together with the Backstop Shares, the “Backstop Securities”).

(b) Funding Notice.

(i) the Parent Share Redemption Amount;

(ii) the Backstop Subscription Amount (as calculated in accordance with Section 1(a) of this Agreement);

(iii) the number of Backstop Shares;

(iv) the number of Backstop Warrants;

(v) the anticipated Closing Date; and

(vi) the Company’s wire instructions.

Notwithstanding the foregoing, for the avoidance of doubt, the “Backstop Subscription Amount” shall be finally calculated without including any shares of Domesticated Parent Common Stock subject to the Parent Shareholder Redemption that have been offered for redemption but subsequently and validly withdrawn by the applicable holder in accordance with the Company’s Memorandum and Articles and applicable Law.

2. Sale and Purchase.

(a) Forward Purchase Securities; Backstop Securities.

(i) The Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, on a private placement basis, 1,500,000 Forward Purchase Shares and 1,666,667 Forward Purchase Warrants for an aggregate purchase price of $15,000,000 (the “FPS Purchase Price”).

(ii) Subject to the terms and conditions hereof, the Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, on a private placement basis, the Backstop Shares and the Backstop Warrants for an aggregate purchase price equal to the Backstop Subscription Amount.

(iii) Each Forward Purchase Warrant and Backstop Warrant will have the same terms as the Parent Private Placement Warrants, and will be subject to the terms and conditions of the Warrant Agreement. Each Forward Purchase Warrant and Backstop Warrant will entitle the holder thereof to purchase one share of Domesticated Parent Common Stock at a price of $11.50 per share, subject to adjustment as described in the Warrant Agreement. The Forward Purchase Warrants and Backstop Warrants will become exercisable thirty (30) days after the Merger Closing and will expire five (5) years after the Merger Closing or upon redemption or the liquidation of the Company, if earlier, as described in the Warrant Agreement.

(iv) The delivery of the Funding Notice hereunder shall serve as notice to the Purchaser that the Purchaser will be required to pay the FPS Purchase Price and the Backstop Subscription Amount, and acquire the Forward Purchase Securities and the Backstop Securities, at the FPS/BPS Closing (as defined below).

(v) The closing of the sale of the Forward Purchase Securities and the Backstop Securities (the “FPS/BPS Closing”) shall be held on the Closing Date and immediately prior to the Merger Closing. At the FPS/BPS Closing, the Company will issue to the Purchaser the Forward Purchase Securities and the Backstop Securities, if any, each registered in the name of the Purchaser, against (and concurrently with) the payment of the FPS Purchase Price and the Backstop Subscription Amount to the Company by wire transfer of immediately available funds to the account notified to the Purchaser by the Company in the Funding Notice.

(b) Delivery of Securities.

(i) The Company shall register the Purchaser as the owner of the Forward Purchase Securities and the Backstop Securities purchased by the Purchaser hereunder (together, the “Securities”) on the Company’s share register and with the Company’s transfer agent by book entry on or promptly after (but in no event more than two (2) Business Days after) the date of the FPS/BPS Closing.

(ii) Each register and book entry for the Securities shall contain a notation, and each certificate (if any) evidencing the Securities shall be stamped or otherwise imprinted with a legend, in substantially the following form:

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE TRANSFERRED IN VIOLATION OF SUCH ACT AND LAWS.”

(c) Legend Removal. If the Securities are eligible to be sold without restriction under, and without the Company being in compliance with the current public information requirements of, Rule 144 under the Securities Act, then at the Purchaser’s request, the Company will cause the Company’s transfer agent to remove the legend set forth in Section 2(b)(ii). In connection therewith, if required by the Company’s transfer agent, the Company will promptly cause an opinion of counsel to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent that authorize and direct the transfer agent to transfer such Securities without any such legend; provided, however, that the Company will not be required to deliver any such opinion, authorization or certificate or direction if it reasonably believes that removal of the legend could result in or facilitate transfers of the Securities in violation of applicable Law.

(d) Registration Rights. The Purchaser shall have registration rights with respect to the Securities as referenced in the Amended and Restated Registration Rights Agreement that will be entered into by and among the Company, the Purchaser, SpinCo and certain other parties thereto in connection with the consummation of the Transactions and the form of which is attached to the Merger Agreement as Exhibit E (the “Registration Rights Agreement”).

(e) Adjustments to Notional Amounts. In the event of any change to the capital structure of the Company, whether dilutive or otherwise, by way of a share dividend, share split, or any other similar transaction however described, the number of Forward Purchase Securities and Backstop Securities, and/or the FPS Purchase Price and Backstop Subscription Amount, as applicable, will be adjusted as necessary to account for such changes.

3. Representations and Warranties of the Purchaser. The Purchaser represents and warrants to each of the Company and SpinCo as follows, as of the date hereof:

(b) Authorization. The Purchaser has full power and authority to enter into this Agreement. This Agreement, when executed and delivered by the Purchaser, will constitute the valid and legally binding obligation of the Purchaser, enforceable in accordance with its terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and any other Laws of general application affecting enforcement of creditors’ rights generally, (b) as limited by Laws relating to the availability of specific performance, injunctive relief or other equitable remedies, or (c) to the extent the indemnification provisions contained in the Registration Rights Agreement may be limited by applicable federal or state securities Laws.

(c) Governmental Consents and Filings.

(n) No Other Representations and Warranties; Non-Reliance. Except for the specific representations and warranties contained in this Section 3 and in any certificate or agreement delivered pursuant hereto, none of the Purchaser nor any person acting on behalf of the Purchaser nor any of the Purchaser’s affiliates (the “Purchaser Parties”) has made, makes or shall be deemed to make any other express or implied representation or warranty with respect to the Purchaser or the purchase and sale of the Securities, and the Purchaser Parties disclaim any such representation or warranty. Except for the specific representations and warranties expressly made by the Company in Section 4 of this Agreement and in any certificate or agreement delivered pursuant hereto, the Purchaser Parties specifically disclaim that they are relying upon any other representations or warranties that may have been made by the Company, any person on behalf of the Company or any of the Company’s affiliates (collectively, the “Company Parties”).

5. Additional Agreements, Acknowledgements and Waivers of the Purchaser.

(a) Trust Account. The Purchaser acknowledges that the Company is a blank check company with the powers and privileges to effect a Business Combination. The Purchaser further acknowledges that, as described in the prospectus included in the registration statement of the Company (the “Prospectus”) available at www.sec.gov, substantially all of the Company’s assets consist of the cash proceeds of the IPO and private placements of its securities, and substantially all of those proceeds have been deposited in a trust account for the benefit of the Company, certain of its public shareholders and the underwriters of the IPO (the “Trust Account”). The Purchaser acknowledges that, except with respect to interest earned on the funds held in the Trust Account that may be released to the Company to pay its franchise Tax, income Tax and similar obligations, the Trust Agreement provides that cash in the Trust Account may be disbursed only (i) if the Company completes one or more transactions that constitute a Business Combination, then to those Persons and in such amounts as described in the Prospectus; (ii) if the Company fails to complete a Business Combination within the allotted time period and liquidates, subject to the terms of the Trust Agreement, to the Company in limited amounts to permit the Company to pay the costs and expenses of its liquidation and dissolution, and then to the Company’s public shareholders; and (iii) if the Company holds a shareholder vote to amend the Company’s Governing Documents to modify the substance or timing of the obligation to redeem 100% of the shares of Parent Common Stock if the Company fails to complete a Business Combination within the allotted time period, then for the redemption of any shares of Parent Common Stock properly tendered in connection with such vote. For and in consideration of the Company entering

into this Agreement, the receipt and sufficiency of which are hereby acknowledged, the Purchaser hereby irrevocably waives any right, title, interest or claim of any kind they have or may have in the future in or to any monies in the Trust Account (including any distributions therefrom) and agree not to seek recourse against the Trust Account or any funds distributed therefrom as a result of, or arising out of, this Agreement and any negotiations, Contracts or agreements with the Company; provided, however, that nothing herein shall serve to limit or prohibit the Purchaser’s right to pursue a claim against the Company for legal relief against monies or other assets held outside the Trust Account, for specific performance or other equitable relief in connection with the consummation of the Transactions so long as such claim would not affect the Company’s ability to fulfill its obligation to effectuate the Parent Share Redemptions. The Purchaser agrees and acknowledges that such irrevocable waiver is material to this Agreement and specifically relied upon by the Company to induce it to enter in this Agreement, and the Purchaser further intends and understands such waiver to be valid, binding and enforceable under applicable Law. To the extent the Purchaser commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating to the Company, which proceeding seeks, in whole or in part, monetary relief against the Company, the Purchaser hereby acknowledges and agrees that its sole remedy shall be against funds held outside of the Trust Account and that such claim shall not permit the Purchaser (or any party claiming on the Purchaser’s behalf or in lieu of the Purchaser) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein. In the event that the Purchaser commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating to the Company, which proceeding seeks, in whole or in part, relief against the Trust Account (including any distributions therefrom) or the holders of Parent Common Stock, whether in the form of money damages or injunctive relief, the Company shall be entitled to recover from the Purchaser the associated legal fees and costs in connection with any such action, in the event the Company prevails in such action or proceeding.

(b) No Short Sales. The Purchaser hereby agrees that neither it, nor any person or entity acting on its behalf or pursuant to any understanding with it, will engage in any Short Sales with respect to securities of the Company prior to the Merger Closing. For purposes of this Section 5, “Short Sales” shall include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act and all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers.

(c) Voting. The Purchaser hereby agrees that if the Company seeks shareholder approval of the Transaction Proposals, then the Purchaser shall vote any shares of Parent Class A Common Stock owned by it in favor of such Transaction Proposals. If the Purchaser fails to vote any shares of Parent Class A Common Stock it is required to vote hereunder in favor of the Transaction Proposals, the Purchaser hereby grants hereunder to the Company and any representative designated by the Company, without further action by the Purchaser or any other Person, a limited irrevocable power of attorney to effect such vote on behalf of the Purchaser, which power of attorney shall be deemed to be coupled with an interest.

6. QEF Election Information. The Company shall use commercially reasonable efforts to determine whether, in any year, the Company or any subsidiary of the Company is deemed to be a “passive foreign investment company” (a “PFIC”) within the meaning of U.S. Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder (collectively, the “Code”). If the Company determines that the Company or any subsidiary of the Company is a PFIC in any year, for the year of determination and for each year thereafter during which the Purchaser holds an equity interest in the Company, including any Parent Warrants, the Company or such subsidiary shall use commercially reasonable efforts to (a) make available to the Purchaser the information that may be required to make or maintain a “qualified electing fund” election under the Code with respect to the Company and (b) furnish the information required to be reported under Section 1298(f) of the Code.

7. Listing. The Company will use commercially reasonable efforts to maintain the listing of the Parent Class A Common Stock and Domesticated Class A Common Stock (as applicable) on the NASDAQ (or another national securities exchange).

8. FPS/BPS Closing Conditions.

(a) The obligation of the Purchaser to purchase the Securities at the FPS/BPS Closing under this Agreement shall be subject to the fulfillment, at or prior to the FPS/BPS Closing of each of the following conditions, any of which, to the extent permitted by applicable Laws, may be waived by the Purchaser:

(iii) The representations and warranties of the Company set forth in Section 4 of this Agreement shall have been true and correct as of the date hereof and shall be true and correct as of the FPS/BPS Closing, as applicable, with the same effect as though such representations and warranties had been made on and as of such date (other than any such representation or warranty that is made by its terms as of a specified date, which shall be true and correct as of such specified date), except where the failure to be so true and correct would not have a material adverse effect on the Company, or its ability to consummate the transactions contemplated by this Agreement;

(iv) The Company shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by the Company, at or prior to the FPS/BPS Closing; and

(v) No order, writ, judgment, injunction, decree, determination, or award shall have been entered by or with any governmental, regulatory, or administrative authority or any court, tribunal, or judicial, or arbitral body, and no other legal restraint or prohibition shall be in effect, preventing the purchase by the Purchaser of the Securities.

(b) The obligation of the Company to sell the Securities at the FPS/BPS Closing under this Agreement shall be subject to the fulfillment, at or prior to the FPS/BPS Closing of each of the following conditions, any of which, to the extent permitted by applicable Laws, may be waived by the Company:

(i) The Transactions shall be completed substantially concurrently with, and (except in the case of the Domestication) immediately following, the purchase and sale of the Securities hereunder;

(ii) The representations and warranties of the Purchaser set forth in Section 3 of this Agreement shall have been true and correct as of the date hereof and shall be true and correct as of the FPS/BPS Closing, as applicable, with the same effect as though such representations and warranties had been made on and as of such date (other than any such representation or warranty that is made by its terms as of a specified date, which shall be true and correct as of such specified date), except where the failure to be so true and correct would not have a material adverse effect on the Purchaser or its ability to consummate the transactions contemplated by this Agreement;

(iii) The Purchaser shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by the Purchaser at or prior to the FPS/BPS Closing; and

(iv) No order, writ, judgment, injunction, decree, determination, or award shall have been entered by or with any governmental, regulatory, or administrative authority or any court, tribunal, or judicial, or arbitral body, and no other legal restraint or prohibition shall be in effect, preventing the purchase by the Purchaser of the Securities.

9. Termination. This Agreement may be terminated at any time prior to the FPS/BPS Closing:

(a) by mutual written consent of the Company, the Purchaser and SpinCo; or

(b) automatically:

(i) if a Business Combination is not completed within eighteen (18) months from the closing of the IPO, or such later date as may be approved by the Company’s shareholders in accordance with its Governing Documents; or

(ii) upon the termination of the Merger Agreement in accordance with the terms and conditions thereof.

In the event of any termination of this Agreement pursuant to this Section 9, the FPS Purchase Price and the Backstop Subscription Amount (and interest thereon, if any), if previously paid, and all Purchaser’s funds paid in connection herewith shall be promptly returned to the Purchaser, and thereafter this Agreement shall forthwith become null and void and have no effect, without any liability on the part of the Purchaser or the Company and their respective directors, officers, employees, partners, managers, members, or shareholders and all rights and obligations of each party shall cease; provided, however, that nothing contained in this Section 9 shall relieve either party from liabilities or damages arising out of any fraud or willful breach by such party of any of its representations, warranties, covenants or agreements contained in this Agreement. Notwithstanding anything herein to the contrary, from and after any termination of this Agreement pursuant to Section 9(b), the Original Agreement shall automatically resume and continue in full force and effect in accordance with its terms as though it were never amended and restated by this Agreement.

10. Termination Fee.

(a) In the event that this Agreement is terminated by reason of a termination of the Merger Agreement pursuant to Section 9.1(i) thereof, then, concurrently with and as a condition to such termination, the Company shall pay the Purchaser or its designee(s) a termination fee of $12,500,000.00 (the “FPA Termination Fee”) by wire transfer of immediately available funds to an account designated by the Purchaser in writing.

(b) Notwithstanding anything to the contrary set forth in this Agreement, except in the case of Actual Fraud or Willful Breach, if the FPA Termination Fee is paid pursuant to Section 10(a), such payment shall constitute the sole and exclusive remedy of the Purchaser, any of its Subsidiaries or any of its or their respective former, current or future general or limited partners, shareholders, Representatives or assignees against the Company Related Parties for all losses and damages suffered as a result of the failure of the Transactions to be consummated or for a breach or failure to perform hereunder or otherwise, and none of the Company Related Parties shall have any further liability or obligation to Purchaser and such other Persons relating to or arising out of this Agreement or the Transactions.

(c) If the Company fails to pay promptly the FPA Termination Fee when due under this Section 10, and in order to obtain such payment, the Purchaser commences an Action that results in a judgment against the Company for any amount owed thereby under this Section 10, the Company shall reimburse the Purchaser for its reasonable and documented costs and expenses (including reasonable and documented attorneys’ fees) in connection with such Action, together with interest on such amount at a rate equal to (x) the prime rate as published in The Wall Street Journal in effect on the date such payment was required to be made through the date such payment was actually received, plus (y) five percent (5%).

(d) Each of the parties acknowledges that (i) the agreements contained in this Section 10 are an integral part of the Transactions, (ii) without these agreements, the parties would not enter into this Agreement and (iii) the FPA Termination Fee does not constitute a penalty, but rather represents liquidated damages in a reasonable amount that will compensate the Purchaser for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions, which amount would otherwise be impossible to calculate with precision.

(g) Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument.

(h) Headings. The section headings contained in this Agreement are inserted for convenience only and will not affect in any way the meaning or interpretation of this Agreement.

(i) Governing Law. This Agreement, the entire relationship of the parties hereto, and any dispute between the parties (whether at law or in equity, and whether grounded in contract, tort or statute) shall be governed by, construed in accordance with, and interpreted pursuant to the Laws of the State of Delaware, without giving effect to its choice of laws principles.

If any party hereto has breached any representation, warranty or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty or covenant.

(p) Waiver. No waiver by any party hereto of any default, misrepresentation or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation or breach of warranty or covenant hereunder or affect in any way any rights arising because of any prior or subsequent occurrence.

(q) Confidentiality. Except as may be required by Law, regulation or applicable stock exchange listing requirements, unless and until the transactions contemplated hereby and the terms hereof are publicly announced or otherwise publicly disclosed by the Company, the parties hereto shall keep confidential and shall not publicly disclose the existence or terms of this Agreement.

(r) Specific Performance; Enforcement. Each party hereto agrees that irreparable damage may occur in the event any provision of this Agreement was not performed by the Purchaser in accordance with the terms hereof and that the other party(ies) shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or in equity.
