WHEREAS, the Parties desire to effect a merger of Merger Sub with and into Ambrx, with Ambrx continuing as the surviving company as a wholly-owned subsidiary of Parent (the “Merger”), upon the terms and subject to the conditions set forth in this Agreement and in accordance with the Cayman Islands Companies Act (as revised) (the “Companies Act”);

WHEREAS, the board of directors of Ambrx has determined that it is advisable and in the commercial interests of Ambrx to effect the Merger upon the terms and subject to the conditions set forth in this Agreement and in accordance with the provisions of Part XVI of the Companies Act;

WHEREAS, the board of directors of Merger Sub has determined that it is advisable and in the commercial interests of Merger Sub to effect the Merger upon the terms and subject to the conditions set forth in this Agreement and in accordance with the provisions of Part XVI of the Companies Act; and

WHEREAS, Parent, including as the sole shareholder of Merger Sub, has approved the form, terms and provisions of, and the transactions contemplated by, this Agreement.

NOW, THEREFORE, in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and intending to be legally bound hereby, the Parties agree as follows:

ARTICLE I

MERGER

1.1    Closing. Unless the transactions contemplated herein shall have been abandoned and this Agreement is terminated pursuant to Section 5.1, the closing of the Merger and the other transactions contemplated hereby (the “Closing”) shall be effected by the exchange of documents by electronic transmission on the date the conditions set forth in Section 1.4 have been satisfied, unless another date, time or place is agreed to in writing by the Parties. The date on which the Closing actually occurs is hereinafter referred to as the “Closing Date.”

1.2    Effective Time. On the Closing Date, a plan of merger, substantially in the form attached hereto as Exhibit A (the “Plan of Merger”), shall be filed with the Cayman Islands Registrar of Companies, and the Merger shall become effective at the time provided therein in accordance with applicable law (the “Effective Time”).


1.3    The Merger. The Merger shall have the effects set forth in this Agreement and in the applicable provisions of the Companies Act. Without limiting the generality of the foregoing, at the Effective Time, the separate company existence of Merger Sub shall cease and Ambrx shall be the surviving company (the “Surviving Company”) and the Surviving Company’s name shall be “Ambrx Biopharma Cayman, Inc.” Further, at the Effective Time, all the property, rights, privileges, powers and franchises of Merger Sub shall vest in the Surviving Company, and all debts, liabilities and duties of Merger Sub shall become the debts, liabilities and duties of the Surviving Company.

1.4    Conditions to Closing. The respective obligations of each Party to effect the Merger and the other transactions contemplated hereby are subject to the satisfaction or waiver of the following conditions:

(a)    no order by any court or other tribunal of competent jurisdiction shall have been entered and shall continue to be in effect and no law shall have been adopted or be effective, in each case that temporarily or permanently prohibits, enjoins or makes illegal the consummation of the Merger;

(b)    no suit, action or proceeding shall have been brought by any governmental entity, and remain pending, that seeks an order that would prohibit, enjoin or make illegal the consummation of the Merger;

(c)    the shareholders of Ambrx shall have approved the Merger in accordance with the governance documents of Ambrx and the Companies Act (the “Ambrx Shareholder Approval”); and

(d)    the registration statement on Form S-4 with respect to the share of common stock, par value $0.0001 per share, of Parent (“Parent Common Stock”) to be issued pursuant to the Merger (the “Registration Statement”) shall be effective, and there shall be no stop order suspending such effectiveness.

1.5    Conversion of Ordinary Shares. At the Effective Time, by virtue of the Merger and without any action on the part of the Parties, each ordinary share, par value $0.0001 per share, of Ambrx (each, an “Ordinary Share”), that is issued and outstanding immediately prior to the Effective Time (other than the Dissenting Shares (as defined below)) shall be (a) automatically canceled and shall cease to exist and (b) converted into the right to receive one-seventh (1/7th) of one (1) validly issued, fully paid and nonassessable share of common stock, par value $0.0001 per share, of Parent (“Parent Common Stock”) (the “Conversion”). No fractional shares of Parent Common Stock shall be issued in connection with the Conversion, and any such fractional share interests to which a holder of Ordinary Shares would otherwise be entitled shall not entitle such holder to vote or to any other rights as a stockholder of Parent. In lieu of any such fractional shares, each holder of Ordinary Shares who, but for the provisions of this section, would be entitled to receive a fractional share interest of Parent Common Stock pursuant to the Conversion, shall be paid cash, without any interest thereon, pursuant to Section 1.9(c). From and after the Effective

 

2


Time, the Ordinary Shares shall be cancelled and cease to exist, and the holders thereof shall have no further rights in respect thereof other than, and any share certificates formerly representing such Ordinary Shares will represent only, the right to receive shares of Parent Common Stock.

1.6    Conversion of Ambrx Equity Awards.

(a)    At the Effective Time, each option to purchase Ordinary Shares granted under that certain Amended and Restated 2016 Share Incentive Plan of Ambrx (the “2016 Ambrx Incentive Plan”) that is outstanding immediately prior to the Effective Time (each, a “2016 Ambrx Option”), each option to purchase Ordinary Shares granted under that certain 2021 Equity Incentive Plan of Ambrx, as adopted by the Board of Directors of Ambrx on June 3, 2021, and approved by the shareholders of Ambrx on June 9, 2021 (the “2021 Ambrx Incentive Plan”) that is outstanding immediately prior to the Effective Time (each, a “2021 Ambrx Option”), and each option to purchase Ordinary Shares granted as an employment inducement award outside of a plan (each, an “Inducement Option” and together with the 2016 Ambrx Options and 2021 Ambrx Options, the “Ambrx Options”), shall be converted into an option to acquire a number of shares of Parent Common Stock at an adjusted exercise price per share, in each case, as determined under this Section 1.6(a) and those certain (x) Second Amended and Restated 2016 Equity Incentive Plan of Parent (the “Second A&R 2016 Parent Incentive Plan”) which will, as of the Effective Time, amend, restate and be a continuation of the 2016 Ambrx Incentive Plan, (y) Amended and Restated 2021 Equity Incentive Plan of Parent (the “A&R 2021 Parent Incentive Plan”) which will, as of the Effective Time amend, restate and be a continuation of the 2021 Ambrx Incentive Plan and (z) the award agreements applicable to the Inducement Options (the “Inducement Award Agreements” and together with the Second A&R 2016 Parent Incentive Plan and A&R 2021 Parent Incentive Plan, the “Parent Incentive Plans”) which will, as of the Effective Time, be assumed and continued by Parent, as applicable (each such resulting option, a “Converted Option”). Each Converted Option shall be subject to the same terms and conditions as were applicable to such corresponding Ambrx Option immediately prior to the Effective Time, except (i) that the grantor of such Converted Options shall be Parent, (ii) as otherwise provided in this Section 1.6(a), (iii) to the extent such terms or conditions are rendered inoperative by the transactions contemplated hereby and/or (iv) such other immaterial administrative or ministerial changes as Parent may determine are appropriate to effectuate the administration of the Converted Options under the Parent Incentive Plans. Accordingly, effective as of the Effective Time: (a) each such Converted Option shall be exercisable solely for shares of Parent Common Stock; (b) the number of shares of Parent Common Stock subject to each Converted Option shall be determined by dividing (x) the number of Ordinary Shares subject to the corresponding Ambrx Option as of immediately prior to the Effective Time by (y) seven (7), and rounding the resulting number down to the nearest whole number of share of Parent Common Stock (such shares of Parent Common Stock issuable upon exercise of a Converted Option, the “Converted Option Shares”); and (c) the per share exercise price for the Converted Option Shares issuable upon exercise of such Converted Option shall be determined by multiplying (x) the per share exercise price for the Ordinary Shares subject to the Ambrx Option, as in effect immediately prior to the Effective Time, by (y) seven (7), and rounding the resulting exercise price up to the nearest whole cent. Following the Effective Time, all Converted Options resulting from the conversion of 2016 Ambrx Options shall be governed in all respects by the terms and conditions of the Second A&R 2016 Parent Incentive Plan and all Converted Options resulting from the conversion of 2021 Ambrx Options shall be governed in all respects by the terms and conditions of the A&R 2021 Parent Incentive Plan. Following the

 

3


Effective Time, each Converted Option resulting from the conversion of Inducement Options shall be governed in all respects by the terms and conditions of the applicable Inducement Award Agreement.

(b)    At the Effective Time, each award of restricted share units representing the right to receive an issuance of Ordinary Shares granted under the 2021 Ambrx Incentive Plan that is outstanding immediately prior to the Effective Time (each, an “Ambrx RSU Award”), shall be converted into an award of restricted stock units representing the right to receive an issuance of shares of Parent Common Stock, in each case, as determined under this Section 1.6(b) and the A&R 2021 Parent Incentive Plan (each such resulting award of restricted stock units, a “Converted RSU Award”). Each Converted RSU Award shall be subject to the same terms and conditions as were applicable to such corresponding Ambrx RSU Award immediately prior to the Effective Time, except (i) that the grantor of such Converted RSU Award shall be Parent, (ii) as otherwise provided in this Section 1.6(b), (iii) to the extent such terms or conditions are rendered inoperative by the transactions contemplated hereby and/or (iv) such other immaterial administrative or ministerial changes as Parent may determine are appropriate to effectuate the administration of the Converted RSU Award under the Parent Incentive Plans. Accordingly, effective as of the Effective Time: (a) each such Converted RSU Award shall represent the right to receive solely an issuance of shares of Parent Common Stock; and (b) each such Converted RSU Award shall represent the right to receive an issuance of such number of shares of Parent Common Stock determined by dividing (x) the number of Ordinary Shares subject to the corresponding Ambrx RSU Award as of immediately prior to the Effective Time by (y) seven (7), and rounding the resulting number down to the nearest whole number of share of Parent Common Stock. Following the Effective Time, all Converted RSU Awards shall be governed in all respects by the terms and conditions of the A&R 2021 Parent Incentive Plan.

1.7    Treatment of Pre-Closing Parent Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of the issued and outstanding shares of Parent Common Stock as of immediately prior to the Effective, all shares of Parent Common Stock issued and outstanding immediately prior to the Effective Time (including, for the avoidance of doubt, immediately prior to the Conversion and the transactions set forth in Section 1.6), shall be cancelled and no consideration shall be issued in respect thereof.

1.8    Dissenting Shares. Notwithstanding any provision of this Agreement to the contrary and to the extent available under the Companies Act, Ordinary Shares that are issued and outstanding immediately prior to the Effective Time and that are held by shareholders of Ambrx who shall have validly exercised and not effectively withdrawn or lost their rights to dissent from the Merger, or dissenter rights, in accordance with Section 238 of the Companies Act (collectively, “Dissenting Shares”, and holders of Dissenting Shares collectively being referred to as “Dissenting Shareholders”), shall be cancelled and cease to exist at the Effective Time and the Dissenting Shareholders shall not be entitled to receive any shares of Parent Common Stock upon the Conversion and shall instead be entitled to receive only the payment of the fair value of such Dissenting Shares held by them as determined in accordance with the provisions of Section 238 of the Companies Act.

1.9    Exchange Agent and Exchange Procedures.

(a)    Prior to or at the Effective Time, Parent shall deposit or cause to be deposited with Equiniti Trust Company (as exchange agent, the “Exchange Agent”), in trust for the benefit of the holders of Ordinary Shares, issuable upon due surrender by each holder of a certificate representing any such Ordinary Shares (a “Certificate”) (or effective affidavits of loss or stock cancellation and destruction certificate, in the form provided by Ambrx, in lieu thereof) or upon cancellation of any non-certificated Ordinary Shares represented in book-entry form immediately prior to the Effective Time (“Book-Entry Shares”) pursuant to the provisions of this Section 1.9 (the “Exchange Fund”).

(b)    Each holder of Ordinary Shares, upon surrender of a Certificate (or effective affidavit of loss or stock cancellation and destruction certificate, in the form provided by Ambrx, in lieu thereof with respect to certificated Ordinary Shares) or upon cancellation of Book-Entry Shares and delivery of such other documents as may reasonably be required by the Exchange Agent (including with respect to Book-Entry Shares), will be entitled to receive in exchange therefor the number of Parent Common Stock representing, in the aggregate, the whole number of Parent Common Stock, from the Exchange Fund, that such holder has the right to receive pursuant to the Conversion. Any and all Parent Common Stock delivered in accordance with this Section 1.9(b) shall be uncertificated and shall be registered in book-entry form. The amounts as reflected in the immediately preceding sentence shall be delivered as promptly as practicable after receipt by the Exchange Agent of the Certificate (or effective affidavit of loss or stock cancellation and destruction certificate, in the form provided by Ambrx, in lieu thereof with respect to certificated Ordinary Shares) or any applicable documentation with respect to the surrender of Book-Entry Shares, in accordance with the foregoing. Until so surrendered, each such Certificate and Book-Entry Share shall, after the Effective Time, represent for all purposes only the right to receive such Parent Common Stock. The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to Parent Common Stock held by it from time to time hereunder, except that it shall receive and hold all dividends or other distributions paid or distributed with respect thereto for the account of the Persons entitled thereto.

(c)    Parent will direct the Exchange Agent to determine the number of whole shares and fractional shares of Parent Common Stock allocable to each holder of Ordinary Shares entitled to Parent Common Stock pursuant to the Conversion, to aggregate all such fractional shares into whole shares, to sell the whole shares obtained thereby in the open market at the then-prevailing prices on behalf of each holder of Ordinary Shares who otherwise would be entitled to receive fractional share interests and to distribute to each such holder his, her or its ratable share of the total proceeds of such sale, after making appropriate deductions of the amounts required for U.S. federal income tax withholding purposes and after deducting any applicable transfer taxes. The costs and expenses of such sale and distribution, including brokers fees and commissions will be paid by Parent. The sales of fractional shares shall occur as soon after the Effective Time as practicable and as determined by the Exchange Agent. None of the Parties nor the Exchange Agent shall guarantee any minimum sale price for the fractional shares of Parent Common Stock. None of the Parties shall pay any interest on the proceeds from the sale of fractional shares. The Exchange Agent shall have the sole discretion to select the broker-dealers through which to sell the aggregated fractional shares and to determine when, how and at what price to sell such shares.

ARTICLE III

TAX MATTERS

3.1    Tax Treatment. The Parties intend that, for United States federal income tax purposes, (i) the transactions occurring pursuant to this Agreement will qualify as both a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”) and as an exchange described in Section 351(a) of the Code and (ii) with respect to the Merger, this Agreement constitutes a “plan of reorganization” within the meaning of Treasury Regulations Section 1.368-2(g) and Ambrx, Parent and Merger Sub will each be a “party to a reorganization” within the meaning of Section 368(b) of the Code.
