  	Company:	 	ZYMERGEN INC., a Delaware corporation
	Number of Shares of Common Stock:	 	111,529
	Warrant Price:	 	$1.65 per Share
	Issue Date:	 	April 30, 2018
	Expiration Date:	 	April 30, 2028 See also Section 5.1(b).
	Credit Facility:	 	This Warrant to Purchase Common Stock (“Warrant”) is issued in connection with that certain Second Amended and Restated Loan and Security
            Agreement between Silicon Valley Bank and the Company dated as of December 27, 2017 (as the same may be amended, modified, supplemented or restated from time to time, including, without limitation, by that certain First Amendment to Second
            Amended and Restated Loan and Security Agreement dated as of April 30, 2018, collectively, the “Loan Agreement”).


   

  THIS WARRANT CERTIFIES THAT, for good and valuable consideration, SILICON VALLEY BANK (together with any successor or permitted assignee or transferee
    of this Warrant or of any shares issued upon exercise hereof, “Holder”) is entitled to purchase the number of fully paid and non-assessable shares (the “Shares”) of the above-stated common stock (the “Common Stock”)
    of the above-named company (the “Company”) at the above-stated Warrant Price, all as set forth above and as adjusted pursuant to Section 2 of this Warrant, subject to the provisions and upon the terms and conditions set forth in this
    Warrant. Reference is made to Section 5.4 of this Warrant whereby Silicon Valley Bank shall transfer this Warrant to its parent company, SVB Financial Group.

   

  SECTION 1. EXERCISE.

   

  1.1         Method of Exercise. Holder may at any time and from time to time exercise this Warrant, in whole or in part, by delivering to the
    Company the original of this Warrant together with a duly executed Notice of Exercise in substantially the form attached hereto as Appendix 1 and, unless Holder is exercising this Warrant pursuant to a cashless exercise set forth in Section 1.2, a
    check, wire transfer of same-day funds (to an account designated by the Company), or

   

  
  
     

  

  
     

  

  
    

  other form of payment acceptable to the Company for the aggregate Warrant Price for the Shares being purchased.

   

  1.2         Cashless Exercise. On any exercise of this Warrant, in lieu of payment of the aggregate Warrant Price in the manner as specified in
    Section 1.1 above, but otherwise in accordance with the requirements of Section 1.1, Holder may elect to receive Shares equal to the value of this Warrant, or portion hereof as to which this Warrant is being exercised. Thereupon, the Company shall
    issue to the Holder such number of fully paid and non-assessable Shares as are computed using the following formula:

   

  X = Y(A-B)/A

   

  where:

   

  		X =	the number of Shares to be issued to the Holder;


   

  		Y =	the number of Shares with respect to which this Warrant is being exercised (inclusive of the Shares surrendered to the Company in payment of the aggregate Warrant Price);


   

  		A=	the Fair Market Value (as determined pursuant to Section 1.3 below) of one Share; and


   

  		B =	the Warrant Price.


   

  1.3         Fair Market Value. If the Company’s Common Stock is then traded or quoted on a nationally recognized securities exchange,
    inter-dealer quotation system or over-the-counter market (a “Trading Market”), the fair market value of a Share shall be the closing price or last sale price of a share of Common Stock reported for the Business Day immediately before the
    date on which Holder delivers this Warrant together with its Notice of Exercise to the Company. If the Company’s Common Stock is not traded in a Trading Market, the Board of Directors of the Company shall determine the fair market value of a Share in
    its reasonable good faith judgment.

   

  1.4         Delivery of Certificate and New Warrant. Within a reasonable time after Holder exercises this Warrant in the manner set forth in
    Section 1.1 or 1.2 above, the Company shall deliver to Holder a certificate representing the Shares issued to Holder upon such exercise and, if this Warrant has not been fully exercised and has not expired, a new warrant of like tenor representing the
    Shares not so acquired.

   

  1.5         Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation
    of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form, substance and amount to the Company or, in the case of mutilation, on surrender of this Warrant to the Company for
    cancellation, the Company shall, within a reasonable time, execute and deliver to Holder, in lieu of this Warrant, a new warrant of like tenor and amount.

   

  1.6         Treatment of Warrant Upon Acquisition of Company.

   

  
  
    2 

  

  
     

  

  
    

  (a)          Acquisition. For the purpose of this Warrant, “Acquisition” means any transaction or series of related transactions
    involving: (i) the sale, lease, exclusive license, or other disposition of all or substantially all of the assets of the Company (ii) any merger or consolidation of the Company into or with another person or entity (other than a merger or consolidation
    effected exclusively to change the Company’s domicile), or any other corporate reorganization, in which the stockholders of the Company in their capacity as such immediately prior to such merger, consolidation or reorganization, own less than a
    majority of the Company’s (or the surviving or successor entity’s) outstanding voting power immediately after such merger, consolidation or reorganization; or (iii) any sale or other transfer by the stockholders of the Company of shares representing at
    least a majority of the Company’s then-total outstanding combined voting power.

   

  (b)          Treatment of Warrant at Acquisition. In the event of an Acquisition in which the consideration to be received by the Company’s
    stockholders consists solely of cash, solely of Marketable Securities or a combination of cash and Marketable Securities (a “Cash/Public Acquisition”), either (i) Holder shall exercise this Warrant pursuant to Section 1.1 and/or 1.2 and
    such exercise will be deemed effective immediately prior to and contingent upon the consummation of such Acquisition or (ii) if Holder elects not to exercise the Warrant, this Warrant will expire immediately prior to the consummation of such
    Acquisition.

   

  (c)          The Company shall provide Holder with written notice of any Cash/Public Acquisition (together with such reasonable information as Holder
    may reasonably require regarding the treatment of this Warrant in connection with such contemplated Cash/Public Acquisition giving rise to such notice), which is to be delivered to Holder not less than seven (7) Business Days prior to the closing of
    the proposed Cash/Public Acquisition. In the event the Company does not provide such notice, then if, immediately prior to the Cash/Public Acquisition, the fair market value of one Share (or other security issuable upon the exercise hereof) as
    determined in accordance with Section 1.3 above would be greater than the Warrant Price in effect on such date, then this Warrant shall automatically be deemed on and as of such date to be exercised pursuant to Section 1.2 above as to all Shares (or
    such other securities) for which it shall not previously have been exercised, and the Company shall promptly notify the Holder of the number of Shares (or such other securities) issued upon such exercise to the Holder and Holder shall be deemed to have
    restated each of the representations and warranties in Section 4 of the Warrant as the date thereof.

   

  (d)          Upon the closing of any Acquisition other than a Cash/Public Acquisition defined above, the acquiring, surviving or successor entity shall
    assume the obligations of this Warrant, and this Warrant shall thereafter be exercisable for the same securities and/or other property as would have been paid for the Shares issuable upon exercise of the unexercised portion of this Warrant as if such
    Shares were outstanding on and as of the closing of such Acquisition, subject to further adjustment from time to time in accordance with the provisions of this Warrant.

   

  (e)          As used in this Warrant, “Marketable Securities” means securities meeting all of the following requirements: (i) the issuer
    thereof is then subject to the reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is then current in its filing of all required reports and other

   

  
  
    3 

  

  
     

  

  
    

  information under the Act and the Exchange Act; (ii) the class and series of shares or other security of the issuer that would be received by Holder in connection with
    the Acquisition were Holder to exercise this Warrant on or prior to the closing thereof is then traded in Trading Market, and (iii) following the closing of such Acquisition, Holder would not be restricted from publicly re-selling all of the issuer’s
    shares and/or other securities that would be received by Holder in such Acquisition were Holder to exercise or convert this Warrant in full on or prior to the closing of such Acquisition, except to the extent that any such restriction (x) arises solely
    under federal or state securities laws, rules or regulations, and (y) does not extend beyond six (6) months from the closing of such Acquisition.

   

  SECTION 2. ADJUSTMENTS TO THE SHARES AND WARRANT PRICE.

   

  2.1         Stock Dividends, Splits, Etc. If the Company declares or pays a dividend or distribution on the outstanding shares of the Common
    Stock payable in securities or property (other than cash), then upon exercise of this Warrant, for each Share acquired, Holder shall receive, without additional cost to Holder, the total number and kind of securities and property which Holder would
    have received had Holder owned the Shares of record as of the date the dividend or distribution occurred. If the Company subdivides the outstanding shares of the Common Stock by reclassification or otherwise into a greater number of shares, the number
    of Shares purchasable hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased. If the outstanding shares of the Common Stock are combined or consolidated, by reclassification or otherwise, into a lesser
    number of shares, the Warrant Price shall be proportionately increased and the number of Shares shall be proportionately decreased.

   

  2.2         Reclassification, Exchange, Combinations or Substitution. Upon any event whereby all of the outstanding shares of the Common Stock
    are reclassified, exchanged, combined, substituted, or replaced for, into, with or by Company securities of a different class and/or series, then from and after the consummation of such event, this Warrant will be exercisable for the number, class and
    series of Company securities that Holder would have received had the Shares been outstanding on and as of the consummation of such event, and subject to further adjustment thereafter from time to time in accordance with the provisions of this Warrant.
    The provisions of this Section 2.2 shall similarly apply to successive reclassifications, exchanges, combinations substitutions, replacements or other similar events.

   

  2.3         Intentionally Omitted.

   

  2.4         Intentionally Omitted.

   

  2.5         No Fractional Share. No fractional Share shall be issuable upon exercise of this Warrant and the number of Shares to be issued
    shall be rounded down to the nearest whole Share. If a fractional Share interest arises upon any exercise of the Warrant, the Company shall eliminate such fractional Share interest by paying Holder in cash the amount computed by multiplying the
    fractional interest by (i) the fair market value (as determined in accordance with Section 1.3 above) of a full Share, less (ii) the then-effective Warrant Price.

   

  2.6         Notice/Certificate as to Adjustments. Upon each adjustment of the Warrant Price, Common Stock and/or number of Shares, the Company,
    at the Company’s expense, shall notify

   

  
  
    4 

  

  
     

  

  
   

   

  Holder in writing within a reasonable time setting forth the adjustments to the Warrant Price, class and/or number of Shares and facts upon which such adjustment is
    based. The Company shall, upon written request from Holder, furnish Holder with a certificate of its Chief Financial Officer, including computations of such adjustment and the Warrant Price, class and number of Shares in effect upon the date of such
    adjustment.

   

  SECTION 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

   

  3.1         Representations and Warranties. The Company represents and warrants to, and agrees with, the Holder as follows:

   

  (a)          The initial Warrant Price referenced on the first page of this Warrant is not greater than the Company’s current 409a valuation price per
    share on the Issue Date hereof.

   

  (b)          All Shares which may be issued upon the exercise of this Warrant shall, upon issuance, be duly authorized, validly issued, fully paid and
    non-assessable, and free of any liens and encumbrances except for restrictions on transfer provided for herein or under applicable federal and state securities laws. The Company covenants that it shall at all times cause to be reserved and kept
    available out of its authorized and unissued capital stock such number of securities as will be sufficient to permit the exercise in full of this Warrant.

   

  (c)          The Company’s capitalization table attached hereto as Schedule 1 is true and complete, in all material respects, as of the Issue Date.

   

  3.2         Notice of Certain Events. If the Company proposes at any time to:

   

  (a)          declare any dividend or distribution upon the outstanding shares of the Company’s common stock, whether in cash, property, stock, or other
    securities and whether or not a regular cash dividend;

    Company’s stock (other than pursuant to contractual pre-emptive rights);

   

  (c)          effect any reclassification, exchange, combination, substitution, reorganization or recapitalization of the outstanding shares of the

  (e)          effect an initial, underwritten offering and sale of its securities to the public pursuant to an effective registration statement under the
    Act (the “IPO”);

   

  then, in connection with each such event, the Company shall give Holder:

   

  (1)          in the case of the matters referred to in (a) and (b) above, at least seven (7) Business Days prior written notice of the

  rights (and specifying the date on which the holders of outstanding shares of the Common Stock will be entitled thereto) or for determining rights to vote, if
    any;

   

  (2)          in the case of the matters referred to in (c) and (d) above at least seven (7) Business Days prior written notice of the date

  SECTION 4. REPRESENTATIONS, WARRANTIES OF THE HOLDER.

   

  The Holder represents and warrants to the Company as follows:

   

  4.1         Purchase for Own Account. This Warrant and the Shares to be acquired upon exercise of this Warrant by Holder are being acquired for
    investment for Holder’s account, not as a nominee or agent, and not with a view to the public resale or distribution within the meaning of the Act. Holder also represents that it has not been formed for the specific purpose of acquiring this Warrant or
    the Shares.

   

  4.2         Disclosure of Information. Holder is aware of the Company’s business affairs and financial condition and has received or has had
    full access to all the information it considers necessary or appropriate to make an informed investment decision with respect to the acquisition of this Warrant and its underlying securities. Holder further has had an opportunity to ask questions and
    receive answers from the Company regarding the terms and conditions of the offering of this Warrant and its underlying securities and to obtain additional information (to the extent the Company possessed such information or could acquire it without
    unreasonable effort or expense) necessary to verify any information furnished to Holder or to which Holder has access.

   

  4.3         Investment Experience. Holder understands that the purchase of this Warrant and its underlying securities involves substantial
    risk. Holder has experience as an investor in securities of companies in the development stage and acknowledges that Holder can bear the economic risk of such Holder’s investment in this Warrant and its underlying securities and has such knowledge and
    experience in financial or business matters that Holder is capable of evaluating the merits and risks of its investment in this Warrant and its underlying securities and/or has a preexisting personal or business relationship with the Company and
    certain of its officers, directors or controlling persons of a nature and duration that enables Holder to be aware of the character, business acumen and financial circumstances of such persons.

   

  
  
    6 

  

  
     

  

  
    

  4.4         Accredited Investor Status. Holder is an “accredited investor” within the meaning of Regulation D promulgated under the Act.

   

  4.5         The Act. Holder understands that this Warrant and the Shares issuable upon exercise hereof have not been registered under the Act
    in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Holder’s investment intent as expressed herein. Holder understands that this Warrant and the Shares issued upon any exercise
    hereof must be held indefinitely unless subsequently registered under the Act and qualified under applicable state securities laws, or unless exemption from such registration and qualification are otherwise available. Holder is aware of the provisions
    of Rule 144 promulgated under the Act.

   

  4.6         Market Stand-off Agreement. The Holder agrees that the Shares shall be subject to the Market Standoff provisions in Section 2.12 of
    its Amended and Restated Investor Rights Agreement, as the same may be amended or amended and restated from time to time.

   

  4.7         No Voting Rights. Holder, as a Holder of this Warrant, will not have any voting rights until the exercise of this Warrant.

   

  4.8         Disqualification. Neither Holder, nor any person or entity with whom Holder shares beneficial ownership of Company securities, is
    subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(l)(i) to (viii) under the Act.

   

  SECTION 5. MISCELLANEOUS.

   

  5.1         Term and Automatic Conversion Upon Expiration.

   

  (a)          Term. Subject to the provisions of Section 1.6 above, this Warrant is exercisable in whole or in part at any time and from time to
    time on or before 6:00 PM, Pacific time, on the Expiration Date and shall be void thereafter.

   

  (b)          Automatic Cashless Exercise upon Expiration. In the event that, upon the Expiration Date, the fair market value of one Share (or
    other security issuable upon the exercise hereof) as determined in accordance with Section 1.3 above is greater than the Warrant Price in effect on such date, then this Warrant shall automatically be deemed on and as of such date to be exercised
    pursuant to Section 1.2 above as to all Shares (or such other securities) for which it shall not previously have been exercised, and the Company shall, within a reasonable time, deliver a certificate representing the Shares (or such other securities)
    issued upon such exercise to Holder.

   

  5.2         Legends. The Shares (and the securities issuable, directly or indirectly, upon conversion of the Shares, if any) shall be imprinted
    with a legend in substantially the following form, together with any such legends as may be required by the Company’s bylaws as in effect from time to time or by applicable federal or state securities laws:

    without limitation, the delivery of investment representation letters and legal opinions reasonably satisfactory to the Company, as reasonably requested by the Company). The Company shall not require Holder to provide an opinion of counsel if the
    transfer is to SVB Financial Group (Silicon Valley Bank’s parent company) or any other affiliate of Holder, provided that any such transferee is an “accredited investor” as defined in Regulation D promulgated under the Act. Additionally, the Company
    shall also not require an opinion of counsel if there is no material question as to the availability of Rule 144 promulgated under the Act.

   

  5.4         Transfer Procedure. After receipt by Silicon Valley Bank of the executed Warrant, Silicon Valley Bank will transfer all of this
    Warrant to its parent company, SVB Financial Group. By its acceptance of this Warrant, SVB Financial Group hereby makes to the Company each of the representations and warranties set forth in Section 4 hereof and agrees to be bound by all of the terms
