 APPENDIX A 

Right of First Refusal 

1.    General. Prior to the effective date of a registration statement under the Securities Act, covering
any shares of the Company’s Common Stock and until such time as the Company shall have effected a public offering of its Common Stock registered under the Securities Act, in the event that, at any time when the Holder (which term for purposes
of this section shall mean the Holder and his or her executors, administrators and any other person to whom this Option may be transferred by will or the laws of descent and distribution) is permitted to do so, the Holder desires to sell, assign or
otherwise transfer any of the shares issued upon the exercise of this Option, the Holder shall first offer such shares to the Company by giving written notice of the Holder’s desire so to sell, assign or transfer such shares. 

2.    Notice of Intended Transfer. The notice shall state the number of shares offered, the name of the
person or persons to whom it is proposed to sell, assign or transfer such shares and the price at which such shares are intended to be sold, assigned or transferred. Such notice shall constitute an offer to the Company for the Company to purchase
the number of shares set forth in the notice at a price per share equal to the price stated therein. 

3.    Company to Accept or Decline Within 30 Days. The Company may accept the offer as to all, but not less
than all, such shares by notifying the Holder in writing within 30 days after receipt of such notice of its acceptance of the offer. If the offer is accepted, the Company shall have 60 days within which to purchase the offered shares at a price per
share as aforesaid. If within the applicable time periods the Holder does not receive notice of the Company’s intention to purchase the offered shares, or if payment in full of the purchase price is not made by the Company, the offer shall be
deemed to have been rejected and the Holder may transfer title to such shares within 90 days from the date of the Holder’s written notice to the Company of the Holder’s intention to sell, but such transfer shall be made only to the
proposed transferee and at the proposed price as stated in such notice and after compliance with any other provisions of this Option applicable to the transfer of such shares. 

4.    Permitted Transfers. The following transactions shall be exempt from the provisions of this Appendix
A: 
  

	 	(a)	 any transfer of Shares to or for the benefit of any spouse, child or grandchild of the Holder, or to a trust
for their benefit; 

  

	 	(b)	 any transfer pursuant to an effective registration statement filed by the Company under the Act; and

  

	 	(c)	 the sale of all or substantially all of the shares of capital stock of the Company (including pursuant to a
merger or consolidation). 

 5.    Transferred Shares to Remain Subject to Right of First
Refusal. Shares that are so transferred to such transferee shall remain subject to the rights of the Company set forth in this Appendix A. As a condition to such transfer, such transferee shall execute and deliver all such documents as the
Company may require to evidence the binding agreement of such transferee so to remain subject to the rights of the Company. 

6.    Remedies of Company. No sale, assignment, pledge or transfer of any of the shares covered by this
Option shall be effective or given effect on the books of the Company unless all of the applicable provisions of this Appendix A have been duly complied with, and the Company may inscribe on the face of any certificate representing any of such
shares a legend referring to the provisions of this Appendix A. If any transfer of shares is made or attempted in violation of the foregoing restrictions, or if shares are not offered to the Company as required hereby, the Company shall have the
right to purchase such shares from the owner thereof or his transferee at any time before or after the transfer, as herein provided. In addition to any other legal or equitable remedies which it may have, the Company may enforce its rights by
actions for specific performance (to the extent permitted by law) and may refuse to recognize any transferee as one of its stockholders for any purpose, including, without limitation, for purposes of dividend and voting rights, until all applicable
provisions hereof have been complied with. 
 7.    Shares Subject to Right of First Refusal. For purposes
of the Right of First Refusal pursuant to this Appendix A, the term “shares” shall mean any and all new, substituted or additional securities or other property issued to the Holder, by reason of his or her ownership of Common Stock
pursuant to the exercise of this Option, in connection with any stock dividend, liquidating dividend, stock split or other change in the character or amount of any of the outstanding securities of the Company, or any consolidation, merger or sale of
all or substantially all of the assets of the Company. 
 8.    Legends on Stock Certificates. Any
certificate representing shares of stock subject to the provisions of this Appendix A may have endorsed thereon one or more legends, substantially as follows: 
  

	 	(i)	 “Any disposition of any interest in the securities represented by this certificate is subject to
restrictions, and the securities represented by this certificate are subject to certain options, contained in a certain agreement between the record holder hereof and the Company, a copy of which will be mailed to any holder of this certificate
without charge upon receipt by the Company of a written request therefor.” 

  

	 	(ii)	 “The shares of stock represented by this certificate have not been registered under the Securities Act of
1933 or under the securities laws of any state and may not be pledged, hypothecated, sold or otherwise transferred except upon such registration or upon receipt by the Company of an opinion of counsel satisfactory to the Company, in form and
substance satisfactory to the Company, that such registration is not required.” 

9.    Right of First Refusal to Lapse Upon Registration. The restrictions imposed by this Appendix A shall
terminate in all respects upon the effective date of a registration statement under the Securities Act covering any of the Company’s Common Stock.

 Exhibit 10.16 

Ginkgo BioWorks, Inc. 
 Restricted
Stock Unit Agreement 
 Granted Under 2014 Stock Incentive Plan 

1. Grant of Restricted Stock Units. 
 (a)
This agreement (the “Agreement”) evidences the grant by Ginkgo BioWorks, Inc., a Delaware corporation (the “Company”), on                 ,
20     (the “Grant Date”) to                     , an [employee/consultant/director] of the Company (the
“Participant”), of an award of                      restricted stock units (“Restricted Stock Units” or “RSUs”) on the
terms provided herein and in the Company’s 2014 Stock Incentive Plan (the “Plan”). Each vested Restricted Stock Unit represents the right to receive one share (“Share”) of common stock, $0.01 par value per share, of
the Company (“Common Stock”). Unless earlier terminated, the RSUs shall expire and be forfeited at 5:00 p.m., Eastern time, on                 ,
20     (the “Expiration Date”).1 
 (b) Except as
otherwise indicated by the context, the term “Participant”, as used in this Agreement, shall be deemed to include any person who acquires the right to the RSUs validly under their terms. 

2. Vesting Schedule. 
 Subject to
Section 4 and Section 5 of this Agreement, the RSUs will become non-forfeitable (“vest”) upon the satisfaction of both an event condition (the “Event Condition”) and a service
condition (the “Service Condition”) on or before the Expiration Date. The Event Condition will be satisfied on the first to occur of (i) a Change in Control (as defined below) or (ii) the earlier of (x) the date six months
after the closing of the sale of shares of Common Stock in an underwritten public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “Securities Act”) (a “Public Offering”)
or (y) March 15 of the calendar year following the effective date of a Public Offering (the “March 15th Date”). The Service Condition will be satisfied as to 25% of the
original number of RSUs on the first anniversary of the Vesting Commencement Date (as defined below) and (A) prior to the effective date of a Public Offering, as to an additional 1/48th of the original number of RSUs on the corresponding
day of each month following the first anniversary of the Vesting Commencement Date (and if there is no corresponding day, the last day of the month) until the fourth anniversary of the Vesting Commencement Date and (B) on and after the
effective date of a Public Offering, as to an additional 1/16th of the original number of RSUs on the last day of each calendar quarter following the first anniversary of the Vesting Commencement Date until the fourth anniversary of the Vesting
Commencement Date; provided, however, that with respect to the calendar quarter in which the effective date of the Public Offering occurs, the number of RSUs that vest pursuant to clause (B) shall be reduced by the number of RSUs that
previously vested during any month occurring in such calendar quarter pursuant to clause (A). For purposes of this Agreement, “Vesting Commencement Date” shall mean
                , 20    .2 

 

	1 	 Note: Insert the date that is seven years from the date of grant. 

	2 	 The Vesting Commencement Date for new grantees is typically the date services begin. The Vesting Commencement
Date for existing participants (e.g., who are receiving a subsequent grant of RSUs) is typically the date the RSU is granted. 

 For purposes of this Agreement, “Change in Control” means (i) a merger or
consolidation of the Company with or into any other corporation or other entity or person, (ii) a sale, lease, exchange or other transfer in one transaction or a series of related transactions of all or substantially all of the Company’s
assets, or (iii) any other transaction, including the sale by the Company of new shares of its capital stock or a transfer of existing shares of capital stock of the Company, the result of which is that a third party that is not an affiliate of
the Company or its stockholders (or a group of third parties not affiliated with the Company or its stockholders) immediately prior to such transaction acquires or holds capital stock of the Company representing a majority of the Company’s
outstanding voting power immediately following such transaction; provided that the following events shall not constitute a “Change in Control”: (A) a transaction (other than a sale of all or substantially all of the Company’s assets)
in which the holders of the voting securities of the Company immediately prior to the merger or consolidation hold, directly or indirectly, at least a majority of the voting securities in the successor corporation or its parent immediately after the
merger or consolidation; (B) a sale, lease, exchange or other transaction in one transaction or a series of related transactions of all or substantially all of the Company’s assets to an affiliate of the Company; (C) an initial public
offering of any of the Company’s securities; (D) a reincorporation of the Company solely to change its jurisdiction; or (E) a transaction undertaken for the primary purpose of creating a holding company that will be owned in
substantially the same proportion by the persons who held the Company’s securities immediately before such transaction. 
 3. Issuance of Common
Stock Upon Vesting. 
 (a) As soon as administratively practicable following the vesting of any Restricted Stock Units pursuant to
Section 2 of this Agreement, but in no event later than (i) 30 days after the applicable vesting date, or (ii) the March 15th Date if the RSUs vest as a result of an Event Condition that
is a Public Offering, the Company shall deliver to Participant (or Participant’s permitted transferee, if applicable) a number of Shares (either by delivering one or more certificates for such shares or by entering such shares in book entry
form, as determined by the Company in its sole discretion) equal to the number of RSUs subject to this award that vest on the applicable vesting date, unless such RSUs terminate prior to the given vesting date pursuant to Section 5 of this
Agreement; provided, however, that if the RSUs vest as a result of an Event Condition that is a Change in Control, the Company may delay settlement of the RSUs in the same manner in which payment of the consideration payable to the stockholders of
the Company may be delayed in connection with the Change in Control and in all events in compliance with Section 409A of the Code. 

(b) As set forth in Section 10(e) of the Plan, the Company shall have the authority and the right to deduct or withhold, or to require
Participant to remit to the Company, an amount sufficient to satisfy all applicable federal, state and local taxes required by law to be withheld with respect to any taxable event arising in connection with the Restricted Stock Units, including
instructing a broker on Participant’s behalf to sell shares of Common Stock otherwise issuable to Participant upon vesting of the RSUs and submit the proceeds of such sale to the Company. The Company shall not be obligated to deliver any new
certificate representing Shares to Participant or Participant’s legal representative or enter such share of Common Stock in book entry form unless and until Participant or Participant’s legal representative shall have paid or otherwise
satisfied in full the amount of all federal, state and local taxes applicable to the taxable income of Participant resulting from the vesting of the Restricted Stock Units or the issuance of Shares. 

(c) Notwithstanding anything in this Agreement to the contrary, the Company may accelerate the vesting of any or all of the RSUs and may
settle any or all of the RSUs in cash instead of Shares. If an RSU is paid in cash, the amount of cash paid with respect to the RSU will equal the Fair Market Value of a Share on the day immediately preceding the payment date. 

  
 - 2 - 

 4. Continuous Relationship with the Company Required. 

Except as otherwise provided in this Agreement, the RSUs shall not vest unless the Participant, on the applicable vesting date, is, and has
been at all times since the Grant Date, an employee, officer or director of, or consultant or advisor to, the Company or any other entity the employees, officers, directors, consultants, or advisors of which are eligible to receive grants under the
Plan (an “Eligible Participant”). 
 5. Termination of Relationship with the Company. 

(a) Except as provided in subsection (b) below, if the Participant ceases to be an Eligible Participant for any reason, all Restricted
Stock Units which have not vested prior to or in connection with such cessation will thereupon automatically be forfeited, terminated and cancelled as of the applicable cessation date without payment of any consideration by the Company, and
Participant, or Participant’s beneficiary or personal representative, as the case may be, shall have no further rights hereunder. No portion of the RSUs which has not become vested as of the date on which Participant ceases to be an Eligible
Participant shall thereafter become vested. 
 (b) Notwithstanding subsection (a) above, if the Participant ceases to be an Eligible
Participant for any reason prior to the occurrence of the Event Condition after the Grant Date, then all RSUs for which the service condition as set forth in Section 2 of this Agreement has been satisfied shall vest upon the subsequent
occurrence of the Event Condition if the Event Condition occurs prior to the Expiration Date. 
 6. Unsecured Obligation to RSUs. 

Unless and until the RSUs have vested in the manner set forth in Section 2 of this Agreement, Participant will have no right to receive
Common Stock, or other payment, in respect of such RSUs. Prior to actual payment of any vested RSUs, such RSUs will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company. 

7. Agreement in Connection with Initial Public Offering. 

The Participant agrees, in connection with the initial Public Offering, (i) not to (a) offer, pledge, announce the intention to
sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock
or any other securities of the Company or (b) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of shares of Common Stock or other securities of the Company, whether any
transaction described in clause (a) or (b) is to be settled by delivery of securities, in cash or otherwise, during the period beginning on the date of the filing of such registration statement with the Securities and Exchange Commission and
ending 180 days after the date of the final prospectus relating to the offering (plus up to an additional 34 days to the extent requested by the managing underwriters for such offering in order to address FINRA Rule 2711(f)(4) or NYSE Rule 472(f)(4)
or any similar successor provision), and (ii) to execute any agreement reflecting clause (i) above as may be requested by the Company or the managing underwriters at the time of such offering. The Company may impose stop-transfer
instructions with respect to the shares of Common Stock or other securities subject to the foregoing restriction until the end of the “lock-up” period. 

  
 - 3 - 

 8. Withholding. 

No Shares will be issued pursuant to the settlement of the RSUs unless and until the Participant pays to the Company, or makes provision
satisfactory to the Company for payment of, any federal, state or local withholding taxes required by law to be withheld in respect of the RSUs. 
 9.
Transfer Restrictions. 
 (a) The RSUs may not be sold, assigned, transferred, pledged or otherwise encumbered by the Participant,
either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the lifetime of the Participant, this award shall be exercisable only by the Participant.
 
 (b) The Participant agrees that he or she will not transfer any Shares issued pursuant to the settlement of the RSUs unless the
transferee, as a condition to such transfer, delivers to the Company a written instrument confirming that such transferee shall be bound by all of the terms and conditions of Section 7 until the completion of the
lock-up period in connection with the Company’s initial Public Offering. 
 10. Provisions of the Plan.

 This award is subject to the provisions of the Plan (including the provisions relating to amendments to the Plan), a copy of which is
furnished to the Participant with this award. In the event of a conflict between the provisions of the Plan and this Agreement, the provisions of the Plan shall control.
