	II.	 AGREEMENT 

1. Grant of Option. The Administrator of the Company hereby grants to the Participant named in the Notice of Stock Option Grant in Part
I of this Agreement (“Participant”), an option (the “Option”) to purchase the number of Shares set forth in the Notice of Stock Option Grant, at the exercise price per Share set forth in the Notice of
Stock Option Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein by reference. Subject to Section 18 of the Plan, in the event of a conflict between the terms
and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail. 
 If designated in the Notice of
Stock Option Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000
rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option (“NSO”). Further, if for any reason this Option (or portion thereof) shall not qualify as an ISO, then, to the extent of such
nonqualification, such Option (or portion thereof) shall be regarded as a NSO granted under the Plan. In no event shall the Administrator, the Company or any Parent or Subsidiary or any of their respective employees or directors have any liability
to Participant (or any other person) due to the failure of the Option to qualify for any reason as an ISO. 
 2. Exercise of Option.

 (a) Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the
Notice of Stock Option Grant and with the applicable provisions of the Plan and this Option Agreement. 
 (b) Method of Exercise. This
Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which shall
state the election to exercise the Option, the number of Shares with respect to which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company.
The Exercise Notice shall be accompanied by (i) payment of the aggregate Exercise Price as to all Exercised Shares, together with any applicable tax withholding and (ii) if required by the terms of such agreements, counterpart signatures
pages or joinder or adoption agreements to any agreements then in effect with the preferred stockholders of the Company (such as voting agreements, right of first refusal and co-sale agreements and the like)
(the “Preferred Stockholder Agreements”). This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by (i) the aggregate Exercise Price, together with any
applicable tax withholding and (ii) any required Preferred Stockholder Agreement signature pages. 
 III. No Shares shall be
issued pursuant to the exercise of an Option unless such issuance and such exercise comply with Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Participant on the date on which the
Option is exercised with respect to such Shares. 
 1. Participant’s Representations. In the event the Shares have not been
registered under the Securities Act of 1933, as amended (the “Securities Act”), at the time this Option is exercised, Participant shall, if required by the Company, concurrently with the exercise of all or any portion of this
Option, deliver to the Company his or her Investment Representation Statement in the form attached hereto as Exhibit B. 

  
 2 

 2. Lock-Up Period. Participant hereby agrees
that Participant shall not offer, pledge, 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, lend, or otherwise transfer or dispose of, directly
or indirectly, any Common Stock (or other securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other
securities) of the Company held by Participant (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred and eighty
(180) days following the effective date of any registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to accommodate regulatory restrictions on
(i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor
provisions or amendments thereto). 
 Participant agrees to execute and deliver such other agreements as may be reasonably requested by the
Company or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the
Company, Participant shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities
pursuant to a registration statement filed under the Securities Act. The obligations described in this Section 4 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or
Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that
may be promulgated in the future. 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 said one hundred and eighty (180) day (or
other) period. Participant agrees that any transferee of the Option or shares acquired pursuant to the Option shall be bound by this Section 4. 

3. Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the
election of the Participant: 
 (a) cash; 

(b) check; 
 (c) consideration
received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or 
 (d) surrender of
other Shares which (i) shall be valued at their Fair Market Value on the date of exercise, and (ii) must be owned free and clear of any liens, claims, encumbrances or security interests, if accepting such Shares, in the sole discretion of
the Administrator, shall not result in any adverse accounting consequences to the Company. 
 4. Restrictions on Exercise. This Option
may not be exercised until such time as the Plan has been approved by the stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any
Applicable Law. 
 5. Non-Transferability of Option. 

  
 3 

 (a) This Option may not be transferred in any manner otherwise than by will or by the laws
of descent or distribution and may be exercised during the lifetime of Participant only by Participant. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of
Participant. 
 (b) Further, until the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act,
or after the Administrator determines that it is, will, or may no longer be relying upon the exemption from registration of Options under the Exchange Act as set forth in Rule 12h-1(f) promulgated under the
Exchange Act (the “Reliance End Date”), Participant shall not transfer this Option or, prior to exercise, the Shares subject to this Option, in any manner other than (i) to persons who are “family members” (as
defined in Rule 701(c)(3) of the Securities Act) through gifts or domestic relations orders, or (ii) to an executor or guardian of Participant upon the death or disability of Participant. Until the Reliance End Date, the Options and, prior to
exercise, the Shares subject to this Option, may not be pledged, hypothecated or otherwise transferred or disposed of, including by entering into any short position, any “put equivalent position” or any “call equivalent position”
(as defined in Rule 16a-1(h) and Rule 16a-1(b) of the Exchange Act, respectively), other than as permitted in clauses (i) and (ii) of this paragraph. 

6. Term of Option. This Option may be exercised only within the term set out in the Notice of Stock Option Grant, and may be exercised
during such term only in accordance with the Plan and the terms of this Option Agreement. 
 7. Tax Obligations. 

(a) Tax Withholding. Participant agrees to make appropriate arrangements with the Company (or the Parent or Subsidiary employing or
retaining Participant) for the satisfaction of all Federal, state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Participant acknowledges and agrees that the Company may refuse to honor the
exercise and refuse to deliver the Shares if such withholding amounts are not delivered at the time of exercise. 
 (b) Notice of
Disqualifying Disposition of ISO Shares. If the Option granted to Participant herein is an ISO, and if Participant sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the date two
(2) years after the Date of Grant, or (ii) the date one (1) year after the date of exercise, Participant shall immediately notify the Company in writing of such disposition. Participant agrees that Participant may be subject to income
tax withholding by the Company on the compensation income recognized by Participant. 
 (c) Code Section 409A.
Under Code Section 409A, an Option that vests after December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per Share exercise price that is
determined by the Internal Revenue Service (the “IRS”) to be less than the Fair Market Value of a Share on the date of grant (a “discount option”) may be considered “deferred compensation.”
An Option that is a “discount option” may result in (i) income recognition by Participant prior to the exercise of the Option, (ii) an additional twenty percent (20%) federal income tax, and (iii) potential penalty and
interest charges. The “discount option” may also result in additional state income, penalty and interest tax to the Participant. Participant acknowledges that the Company cannot and has not guaranteed that the IRS will agree that the per
Share exercise price of this Option equals or exceeds the Fair Market Value of a Share on the date of grant in a later examination. Participant agrees that if the IRS determines that the Option was granted with a per Share exercise price that was
less than the Fair Market Value of a Share on the date of grant, Participant shall be solely responsible for Participant’s costs related to such a determination. 

  
 4 

 8. Entire Agreement; Governing Law. The Plan is incorporated herein by reference. The
Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject
matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant. This Option Agreement is governed by the internal substantive laws but not the choice of law
rules of California. 
 9. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT
TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR
ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS
A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE
PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 

  
 5 

 Participant acknowledges receipt of a copy of the Plan and represents that he or she is
familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Participant has reviewed the Plan and this Option in their entirety, has had an opportunity to obtain the advice of
counsel prior to executing this Option and fully understands all provisions of the Option. Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under
the Plan or this Option. Participant further agrees to notify the Company upon any change in the residence address indicated below.

Inc. 
 1715 Spruce St. Apt. 2 
 Berkeley, CA 94709-1726 

Attention: Chief Financial Officer 
 1.
Exercise of Option. Effective as of today, _________________, _____, the undersigned (“Participant”) hereby elects to exercise Participant’s option (the “Option”) to purchase
________________ shares of the Common Stock (the “Shares”) of Rigetti & Co, Inc. (the “Company”) under and pursuant to the 2013 Equity Incentive Plan (the “Plan”) and
the Stock Option Agreement dated ________ (the “Option Agreement”). 
 2. Delivery of Payment. Participant
herewith delivers to the Company the full purchase price of the Shares, as set forth in the Option Agreement, and any and all withholding taxes due in connection with the exercise of the Option. 

3. Delivery of Counterpart Signature Pages. If requested by the Company, Participant herewith delivers duly executed counterpart
signature pages to the Preferred Stockholder Agreements (as defined in the Option). 
 4. Representations of Participant. Participant
acknowledges that Participant has received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions. 

5. Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a
duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Common Stock subject to an Award, notwithstanding the exercise of the Option. The Shares shall
be issued to Participant as soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance except as
provided in Section 13 of the Plan. 
 6. Company’s Right of First Refusal. Before any Shares held by Participant or any
transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal
to purchase the Shares on the terms and conditions set forth in this Section 5 (the “Right of First Refusal”). 

(a) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the
“Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”);
(iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Shares (the “Offered Price”), and the
Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 

  
 7 

 (b) Exercise of Right of First Refusal. At any time within thirty (30) days
after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at
the purchase price determined in accordance with subsection (c) below. 
 (c) Purchase Price. The purchase price
(“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 5 shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 

(d) Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or
in the manner and at the times set forth in the Notice. 
 (e) Holder’s Right to Transfer. If all of the Shares proposed in the
Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section 5, then the Holder may sell or otherwise transfer such Shares to such Proposed Transferee at the Offered
Price or at a higher price, provided that such sale or other transfer is consummated within one hundred and twenty (120) days after the date of the Notice, that any such sale or other transfer is effected in accordance with any
applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section 5 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not
transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or
otherwise transferred. 
 (f) Exception for Certain Family Transfers. Anything to the contrary contained in this Section 5
notwithstanding, the transfer of any or all of the Shares during the Participant’s lifetime or on the Participant’s death by will or intestacy to the Participant’s immediate family or a trust for the benefit of the Participant’s
immediate family shall be exempt from the provisions of this Section 5. “Immediate family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other
recipient shall receive and hold the Shares so transferred subject to the provisions of this Section 5, and there shall be no further transfer of such Shares except in accordance with the terms of this Section 5. 

(g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the earlier of (i) the
first sale of Common Stock of the Company to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 

7. Tax Consultation. Participant understands that Participant may suffer adverse tax consequences as a result of Participant’s
purchase or disposition of the Shares. Participant represents that Participant has consulted with any tax consultants Participant deems advisable in connection with the purchase or disposition of the Shares and that Participant is not relying on the
Company for any tax advice. 

  
 8 

 8. Restrictive Legends and Stop-Transfer Orders. 

(a) Legends. Participant understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE
OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN
COMPLIANCE THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST
REFUSAL HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT
OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON
TRANSFER FOR A PERIOD OF TIME FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES AND MAY NOT BE SOLD OR OTHERWISE
DISPOSED OF BY THE HOLDER PRIOR TO THE EXPIRATION OF SUCH PERIOD WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER. 
 (b)
Stop-Transfer Notices. Participant agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the
Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 
 (c) Refusal to
Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Exercise Notice or (ii) to treat as owner of such Shares or
to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred. 
 9.
Successors and Assigns. The Company may assign any of its rights under this Exercise Notice to single or multiple assignees, and this Exercise Notice shall inure to the benefit of the successors and assigns of the Company. Subject to the
restrictions on transfer herein set forth, this Exercise Notice shall be binding upon Participant and his or her heirs, executors, administrators, successors and assigns. 

10. Interpretation. Any dispute regarding the interpretation of this Exercise Notice shall be submitted by Participant or by the Company
forthwith to the Administrator, which shall review such dispute at its next regular meeting. The resolution of such a dispute by the Administrator shall be final and binding on all parties. 

  
 9 

 11. Governing Law; Severability. This Exercise Notice is governed by the internal
substantive laws, but not the choice of law rules, of California. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Exercise Notice shall continue in full
force and effect. 
 12. Entire Agreement. The Plan and Option Agreement are incorporated herein by reference. This Exercise Notice,
the Plan, the Option Agreement and the Investment Representation Statement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company
and Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant.

INVESTMENT REPRESENTATION STATEMENT 
  

					
	PARTICIPANT	  	:	  	
	COMPANY	  	:	  	RIGETTI & CO, INC.
	SECURITY	  	:	  	COMMON STOCK
	AMOUNT	  	:	  	
	DATE	  	:	  	

 In connection with the purchase of the above-listed Securities, the undersigned Participant represents to the
Company the following: 
 (a) Participant is aware of the Company’s business affairs and financial condition and has acquired sufficient
information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Participant is acquiring these Securities for investment for Participant’s own account only and not with a view to, or for resale in
connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 

(b) Participant acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have
not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Participant’s investment intent as expressed herein. In this connection,
Participant understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Participant’s representation was predicated solely upon a present intention to hold these
Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one (1) year or any other fixed period in the
future. Participant further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Participant further acknowledges and
understands that the Company is under no obligation to register the Securities. Participant understands that the certificate evidencing the Securities shall be imprinted with any legend required under applicable state securities laws. 

(c) Participant is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance,
permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701
provides that if the issuer qualifies under Rule 701 at the time of the grant of the Option to Participant, the exercise shall be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting
requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt
under Rule 701 may be resold, subject to the satisfaction of the applicable conditions specified by Rule 144, including in the case of affiliates (1) the availability of certain public information about the Company, (2) the amount of
Securities being sold during any three (3) month period not exceeding specified limitations, (3) the resale being made in an unsolicited “broker’s transaction”, transactions directly with a “market maker” or
“riskless principal transactions” (as those terms are defined under the Securities Exchange Act of 1934) and (4) the timely filing of a Form 144, if applicable. 

  
 11 

 In the event that the Company does not qualify under Rule 701 at the time of grant of the
Option, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which may require (i) the availability of current public information about the Company; (ii) the resale to occur more than a
specified period after the purchase and full payment (within the meaning of Rule 144) for the Securities; and (iii) in the case of the sale of Securities by an affiliate, the satisfaction of the conditions set forth in sections (2), (3) and
(4) of the paragraph immediately above. 
 (d) Participant further understands that in the event all of the applicable requirements of
Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption shall be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of
the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 shall have a substantial burden of proof
in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Participant understands that no assurances
can be given that any such other registration exemption shall be available in such event.

 RIGETTI & CO, INC. 

2013 EQUITY INCENTIVE PLAN 

RESTRICTED STOCK UNIT GRANT NOTICE 

EXHIBIT A 

VESTING SCHEDULE 

The RSU Award will vest and the shares of Common Stock subject to the RSUs will be issued in accordance with the terms of the applicable
Restricted Stock Unit Agreement upon the satisfaction of both the Time-Based Vesting Requirement and the Liquidity-Event Vesting Requirement. Failure to satisfy both of the vesting requirements will result in termination and forfeiture of the RSUs.
A RSU that has satisfied both the Time-Based Vesting Requirement and the Liquidity-Event Vesting Requirement is a “Vested RSU.” As used in the Restricted Stock Unit Agreement, the word “vests” or “vested” means that the
RSU has met both such conditions (unless otherwise specifically provided in the RSU Agreement). 
 Time-Based Vesting Requirement.
The time-based vesting requirement with respect to the RSUs or any time-based installment or tranche of the RSUs is satisfied if the Participant has remained a Service Provider from the Date of Grant of the RSUs through the applicable time-based
vesting date set forth in the Participant’s Grant Notice. Time-based vesting shall cease as of the date that the Participant’s status as a Service Provider ceases for any reason, whether initiated by Participant or the Company, and with or
without Cause, and any RSUs that have not vested under the time-based vesting requirement shall terminate and be forfeited back to the Company on the date that Participant’s Service Provider status terminates. For clarity, once a RSU has
satisfied the time-based vesting requirement, Participant can thereafter terminate its status as a Service Provider before the consummation of a Liquidity Event and the Participant will retain the RSUs that have satisfied time-based vesting, but the
RSUs will terminate upon the Expiration Date. 
 Liquidity-Event Vesting Requirement. The liquidity-event vesting requirement with
respect to the RSUs is satisfied upon the consummation of a Liquidity Event before the Expiration Date of the RSUs. A “Liquidity Event” is the consummation before the Expiration Date of the first to occur of any of the
following: (i) a Change in Control (as defined in the Plan and including the requirement that a transaction will not be deemed a Change in Control unless the transaction qualifies as a change in control event within the meaning of Code
Section 409A of the Code), (ii) the date following the effective date of a registration statement of the Company filed under the Securities Act (as defined in the Plan) for the sale of the Company’s common stock (an
“IPO”), (iii) the settlement of the initial trade of shares of the Company’s common stock on the Nasdaq Global Select Market, the New York Stock Exchange or another exchange or marketplace approved by the Board by means
of an effective registration statement under the Securities Act that registers shares of existing common stock of the Company for resale (a “Direct Listing”), or (iv) the Company’s consummation of a merger or
consolidation with a special purpose acquisition company (“SPAC”) or its subsidiary in which the common stock (or similar securities) of the surviving or parent entity are publicly traded in a public offering pursuant to an
effective registration statement under the Securities Act (a “SPAC Transaction”). 

 RIGETTI & CO, INC. 

2013 EQUITY INCENTIVE PLAN 

RESTRICTED STOCK UNIT AGREEMENT 

Pursuant to the Restricted Stock Unit Grant Notice (the “Grant Notice”) and this Restricted Stock Unit Agreement (the
“Agreement”), Rigetti & Co, Inc. (the “Company”) has awarded you (“Participant”) Restricted Stock Units (sometimes referred to generally herein as the
“Award”) pursuant to Section 9 of the Company’s 2013 Equity Incentive Plan (the “Plan”) for the number of shares of Common Stock (“Stock”) indicated in the Grant
Notice. Capitalized terms not explicitly defined in this Agreement or the Grant Notice will have the same meanings given to them in the Plan. The details of your Award, in addition to those set forth in the Grant Notice, are as follows. 

1. GRANT OF THE RSUS. This Award
represents the right to be issued on a future date one (1) share of Stock for each Restricted Stock Unit that vests on the applicable vesting date(s) (subject to any adjustment under Section 3 below) as indicated in the Grant Notice.
Notwithstanding the foregoing, the Company reserves the right to pay you the cash equivalent of Common Stock, in part or in full satisfaction of the delivery of Stock in connection with the vesting of the RSUs, and, to the extent applicable,
references in this Agreement and the Grant Notice to Stock or Common Stock issuable in connection with your RSUs will include the potential issuance of its cash equivalent pursuant to such right. This Award was granted in consideration of your
services to the Company. 
 2. VESTING. Subject to the limitations contained
herein, your RSUs will vest, if at all, in accordance with the vesting provisions set forth in the Grant Notice, provided that any additional time-based vesting will cease upon the termination of your relationship with the Company as a Service
Provider. Upon such termination of your relationship as a Service Provider, any RSUs that have not satisfied the time-based vesting requirements on the date of such termination will be forfeited at no cost to the Company and you will have no further
right, title or interest in or to the RSUs that are forfeited or such underlying shares of Common Stock. Any RSUs, for which time-based vesting has been satisfied as of the date your status as a Service Provider ends, will remain in existence
following your termination as a Service Provider until the earliest of the Expiration Date of the RSUs, the occurrence of a Liquidity Event (as defined in the Grant Notice), or until any date that termination of the RSUs is otherwise permitted under
the Plan. 
 3. NUMBER OF SHARES. The number of
shares of Stock subject to your Award may be adjusted from time to time for Capitalization Adjustments, as provided in the Plan. Any additional Stock, cash or other property that becomes subject to the Award pursuant to this Section 3, if any,
will be subject, in a manner determined by the Board, to the same forfeiture restrictions, restrictions on transferability, and time and manner of delivery as applicable to the other RSUs and Stock covered by your Award. Notwithstanding the
provisions of this Section 3, no fractional shares or rights for fractional shares of Common Stock will be created pursuant to this Section 3. Any fraction of a share will be rounded down to the nearest whole share. 

4. SECURITIES LAW COMPLIANCE. You may not be issued any Stock under
your Award unless the shares of Stock underlying the RSUs are either (i) then registered under the Securities Act, or (ii) the Company has determined that such issuance would be exempt from the registration requirements of the Securities
Act. Your Award must also comply with other applicable laws and regulations governing the Award, and you will not receive such Stock if the Company determines that such receipt would not be in material compliance with such laws and regulations. 

 5. TRANSFER RESTRICTIONS. Prior
to the time that the Stock subject to your RSUs has been delivered to you, you may not transfer, pledge, sell or otherwise dispose of the RSUs or the Stock issuable in respect of your RSUs, except as expressly provided in this Section 5. For
example, you may not use Stock that may be issued in respect of your RSUs as security for a loan. The restrictions on transfer set forth herein will lapse upon delivery to you of Stock in respect of your vested RSUs. 

(a) Death. Your Award is transferable by will and by the laws of descent and distribution. At your death, vesting of your RSUs will
cease and the executor or administrator of your estate will be entitled to receive, on behalf of your estate, any Stock or other consideration that was payable upon your death in respect of vested RSUs, but which was not paid or issued before your
death. 
 (b) Domestic Relations Orders. Upon receiving written permission from the Board or its duly authorized designee, and
provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your right to receive the distribution of Stock or other consideration hereunder, pursuant to a domestic relations
order or marital settlement agreement or other divorce or separation instrument as permitted by applicable law that contains the information required by the Company to effectuate the transfer. You are encouraged to discuss the proposed terms of any
division of this Award with the Company General Counsel prior to finalizing the domestic relations order or marital settlement agreement to verify that you may make such transfer, and if so, to help ensure the required information is contained
within the domestic relations order or marital settlement agreement. 
 6. DATE OF ISSUANCE.

 (a) The issuance of Stock in respect of the RSUs is intended to comply with Treasury Regulations
Section 1.409A-1(b)(4) and will be construed and administered in such a manner. Subject to the satisfaction of the withholding obligations set forth in this Agreement, in the event one or more RSUs
becomes a Vested RSU, the Company will issue to you one (1) share of Stock for each RSU that vests on the applicable vesting date(s) (subject to any adjustment under Section 3 above). The issuance date determined by this paragraph is
referred to as the “Original Issuance Date.” 
 (b) If the Original Issuance Date falls on a date that is not
a business day, delivery will instead occur on the next following business day. In addition, in the case of an RSU that vests after the first date upon which any security of the Company is listed (or approved for listing) upon notice of issuance on
a national securities exchange or quotation system, if: 
 (i) the Original Issuance Date does not occur
(1) during an “open window period” applicable to you, as determined by the Company in accordance with the Company’s then-effective policy on trading in Company securities, or (2) on a date when you are otherwise permitted to
sell shares of Common Stock on an established stock exchange or stock market, (including but not limited to under a previously established written trading plan that meets the requirements of Rule 10b5-1 under
the Exchange Act and was entered into in compliance with the Company’s policies (a “10b5-1 Arrangement”)), and  

(ii) either: (1) Withholding Taxes (as defined in Section 11) do not apply; or (2) the Company decides, prior to the
Original Issuance Date: (A) not to satisfy the Withholding Taxes by withholding shares of Common Stock from the shares otherwise due, on the Original Issuance Date, to you under this Award; (B) not to permit you to enter into a “same
day sale” commitment with a broker-dealer pursuant to Section 11 of this Agreement (including but not limited to a commitment under a 10b5-1 Arrangement); and (C) not to permit you to pay your
Withholding Taxes in cash, then the shares that would otherwise be issued to you on the Original Issuance Date will not be delivered on such Original Issuance Date and will instead be delivered on the first business day when you are not
prohibited from selling shares of the Company’s Common Stock in the open public market, but in no event later than December 31 of the 

 
calendar year in which the Original Issuance Date occurs (that is, the last day of your taxable year in which the Original Issuance Date occurs), or, if and only if permitted in a manner
that complies with Treasury Regulations Section 1.409A-1(b)(4), no later than the date that is the 15th day of the third calendar month of the applicable year following the year in which the shares of
Common Stock under this Award are no longer subject to a “substantial risk of forfeiture” within the meaning of Treasury Regulations Section 1.409A-1(d). 

(c) The form of delivery (e.g., a stock certificate or electronic entry evidencing such shares) will be determined by the
Company. 
 7. DIVIDENDS. You will receive no benefit or adjustment to your Award
with respect to any cash dividend, stock dividend or other distribution that does not result from a Capitalization Adjustment; provided, however, that this sentence will not apply with respect to any shares of Stock that are delivered to you in
connection with your Award after such shares have been delivered to you. 
 8. RESTRICTIVE
LEGENDS. The shares of Stock issued under your Award will be endorsed with appropriate legends as determined by the Company. 

9. EXECUTION OF DOCUMENTS. You hereby acknowledge and
agree that the manner selected by the Company by which you indicate your consent to your Grant Notice is also deemed to be your execution of your Grant Notice and of this Agreement. You further agree that such manner of indicating consent may be
relied upon as your signature for establishing your execution of any documents to be executed in the future in connection with your Award. 

10. AWARD NOT A SERVICE CONTRACT. 

(a) Nothing in this Agreement (including, but not limited to, the vesting of your RSUs or the issuance of the Stock subject to your
RSUs), the Plan or any covenant of good faith and fair dealing that may be found implicit in this Agreement or the Plan, will: (i) confer upon you any right to continue in the employ of, or affiliation with, the Company or a Parent or
Subsidiary (an “Affiliate”); (ii) constitute any promise or commitment by the Company or an Affiliate regarding the fact or nature of future positions, future work assignments, future compensation or any other term or
condition of employment or affiliation; (iii) confer any right or benefit under this Agreement or the Plan unless such right or benefit has specifically accrued under the terms of this Agreement or Plan; or (iv) deprive the Company of the
right to terminate you at will and without regard to any future vesting opportunity that you may have. 
 (b) By accepting this Award,
you acknowledge and agree that the right to continue vesting in the RSUs pursuant to the vesting schedule provided in the Grant Notice may not be earned unless (in addition to any other conditions described in the Grant Notice and this Agreement)
you continue as an employee, director or consultant at the will of the Company and affiliate, as applicable (not through the act of being hired, being granted this Award or any other award or benefit) and that the Company has the right to
reorganize, sell, spin-out or otherwise restructure one or more of its businesses or Affiliates at any time or from time to time, as it deems appropriate (a “reorganization”). You
acknowledge and agree that such a reorganization could result in the termination of your relationship as a Service Provider, or the termination of Affiliate status of your employer and the loss of benefits available to you under this Agreement,
including but not limited to, the termination of the right to continue vesting in the RSUs. You further acknowledge and agree that this Agreement, the Plan, the transactions contemplated hereunder and the vesting schedule set forth herein or any
covenant of good faith and fair dealing that may be found implicit in any of them do not constitute an express or implied promise of continued engagement as an employee or consultant for the term of this Agreement, for any period, or at all, and
will not interfere in any way with the Company’s right to terminate your relationship as a Service Provider at any time, with or without your cause or notice, or to conduct a reorganization. 

 11. WITHHOLDING OBLIGATIONS. 

(a) On each vesting date, and on or before the time you receive a distribution of the Stock underlying your RSU, and at any other time
as reasonably requested by the Company in accordance with applicable tax laws, you hereby authorize any required withholding from the Common Stock issuable to you and/or otherwise agree to make adequate provision in cash for any sums required to
satisfy the federal, state, local and foreign tax withholding obligations of the Company or any Affiliate that arise in connection with your Award (the “Withholding Taxes”). Additionally, the Company or any Affiliate may, in
its sole discretion, satisfy all or any portion of the Withholding Taxes obligation relating to your Award by any of the following means or by a combination of such means: (i) withholding from any compensation otherwise payable to you by the
Company; (ii) causing you to tender a cash payment; (iii) permitting or requiring you to enter into a “same day sale” commitment, if applicable, with a broker-dealer that is a member of the Financial Industry Regulatory Authority
(a “FINRA Dealer”) whereby you irrevocably elect to sell a portion of the shares of Stock to be delivered in connection with your RSU to satisfy the Withholding Taxes and whereby the FINRA Dealer irrevocably commits to
forward the proceeds necessary to satisfy the Withholding Taxes directly to the Company and/or its Affiliates; or (iv) withholding shares of Common Stock from the Stock issued or otherwise issuable to you in connection with the RSUs with a Fair
Market Value (measured as of the date such Stock is issued to you pursuant to Section 6) equal to the amount of such Withholding Taxes; provided, however, that the number of such shares of Common Stock so withheld will not exceed the amount
necessary to satisfy the Company’s required tax withholding obligations using the minimum statutory withholding rates for federal, state, local and foreign tax purposes, including payroll taxes, that are applicable to supplemental taxable
income; and provided further, that to the extent necessary to qualify for an exemption from application of Section 16(b) of the Exchange Act, if applicable, such share withholding procedure will be subject to the express prior approval of the
Company’s Compensation Committee. 
 (b) Unless the tax withholding obligations of the Company and/or any Affiliate are
satisfied, the Company will have no obligation to deliver to you any Stock. 
 (c) In the event the Company’s obligation to
withhold arises prior to the delivery to you of Stock or it is determined after the delivery of Stock to you that the amount of the Company’s withholding obligation was greater than the amount withheld by the Company, you agree to indemnify and
hold the Company harmless from any failure by the Company to withhold the proper amount. 
 12. TAX
CONSEQUENCES. The Company has no duty or obligation to minimize the tax consequences to you of this Award and will not be liable to you for any adverse tax consequences to you arising in connection
with this Award. You are hereby advised to consult with your own personal tax, financial and/or legal advisors regarding the tax consequences of this Award and by signing the Grant Notice, you have agreed that you have done so or knowingly and
voluntarily declined to do so. You understand that you (and not the Company) will be responsible for your own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. 

13. UNSECURED OBLIGATION. Your Award is unfunded, and as a holder of a
vested RSUs, you will be considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to issue shares or other property pursuant to this Agreement. You will not have voting or any other rights as a
stockholder of the Company with respect to the Stock to be issued pursuant to this Agreement until such Stock is issued to you pursuant to Section 6 of this Agreement. Upon such issuance, you will obtain full voting and other rights as a
stockholder of the Company. Nothing contained in this Agreement, and no action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person.

 14. NOTICES. Any notice or request required or
permitted hereunder will be given in writing to each of the other parties hereto and will be deemed effectively given on the earlier of (i) the date of personal delivery, including delivery by express courier, or delivery via electronic means,
or (ii) the date that is five (5) days after deposit in the United States Post Office (whether or not actually received by the addressee), by registered or certified mail with postage and fees prepaid, addressed at the following addresses,
or at such other address(es) as a party may designate by ten (10) days’ advance written notice to each of the other parties hereto:

PARTICIPANT: Your address as on file with the Company at the time notice is given 

15. HEADINGS. The headings of the Sections in this Agreement are inserted for convenience only and
will not be deemed to constitute a part of this Agreement or to affect the meaning of this Agreement. 
 16. MISCELLANEOUS.

 (a) The rights and obligations of the Company under your Award will be transferable by the Company to any one or more persons
or entities, and all covenants and agreements hereunder will inure to the benefit of, and be enforceable by, the Company’s successors and assigns. 

(b) You agree upon request to execute any further documents or instruments necessary or desirable in the sole determination of the
Company to carry out the purposes or intent of your Award.

national securities exchanges as may be required. 
 (e) All obligations of the Company under the Plan and this Agreement will be
binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company. 

17. GOVERNING PLAN DOCUMENT. Your RSUs are subject to all the
provisions of the Plan, the provisions of which are hereby made a part of your Award, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan. Your
RSU (and any compensation paid or Stock issued under your RSU) is subject to recoupment in accordance with The Dodd–Frank Wall Street Reform and Consumer Protection Act and any implementing regulations thereunder, any clawback policy adopted by
the Company and any compensation recovery policy otherwise required by applicable law. No recovery of compensation under such a clawback policy will be an event giving rise to a right to voluntarily terminate employment upon a resignation for
“good reason,” or for a “constructive termination” or any similar term under any plan of or agreement with the Company. 

 18. EFFECT ON OTHER
EMPLOYEE BENEFIT PLANS. The value of the RSUs subject to this Agreement will not be included as compensation, earnings, salaries, or other similar terms used when
calculating benefits under any employee benefit plan (other than the Plan) sponsored by the Company or any Affiliate except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any or
all of the employee benefit plans of the Company or any Affiliate. 
 19. CHOICE OF
LAW. The interpretation, performance and enforcement of this Agreement will be governed by the law of the state of Delaware without regard to that state’s conflicts of laws rules. The parties
submit to the jurisdiction of any state or federal courts encompassing the Company’s then principal offices for the resolution of any claims or disputes arising under this Agreement. 

20. SEVERABILITY. If all or any part of this Agreement or the Plan is declared by any
court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Agreement (or part of such a
Section) so declared to be unlawful or invalid will, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 

21. AMENDMENT. This Agreement may not be modified, amended or terminated except by an
instrument in writing, signed by you and by a duly authorized representative of the Company. Notwithstanding the foregoing, this Agreement may be amended solely by the Board by a writing which specifically states that it is amending this Agreement,
so long as a copy of such amendment is delivered to you, and provided that, except as otherwise expressly provided in the Plan, no such amendment materially adversely affecting your rights hereunder may be made without your written consent. Without
limiting the foregoing, the Board reserves the right to change, by written notice to you, the provisions of this Agreement in any way it may deem necessary or advisable to carry out the purpose of the Award as a result of any change in applicable
laws or regulations or any future law, regulation, ruling, or judicial decision, provided that any such change will be applicable only to rights relating to that portion of the Award which is then subject to restrictions as provided herein. 

 22. COMPLIANCE WITH
SECTION 409A OF THE CODE. The RSUs are intended to be exempt from the application of Section 409A of the Code,
including but not limited to by reason of complying with the “short-term deferral” rule set forth in Treasury Regulation Section 1.409A-1(b)(4) and any ambiguities herein will be interpreted
accordingly. Notwithstanding the foregoing, if it is determined that the RSUs fail to satisfy the requirements of the short-term deferral rule and are otherwise not exempt from, and determined to be deferred compensation subject to Section 409A
of the Code, this Award will comply with Section 409A to the extent necessary to avoid adverse personal tax consequences and any ambiguities herein will be interpreted accordingly. If it is determined that the RSUs are deferred compensation
subject to Section 409A and you are a “specified employee” (within the meaning set forth in Section 409A(a)(2)(B)(i) of the Code) as of the date of your “separation from service” (within the meaning of Treasury
Regulation Section 1.409A-1(h) and without regard to any alternative definition thereunder), then the issuance of any Stock that would otherwise be made upon the date of the separation from service, or
within the first six (6) months thereafter will not be made on the originally scheduled date(s) and will instead be issued in a lump sum on the date that is six (6) months and one day after the date of the separation from service, with the
balance of the Stock issued thereafter in accordance with the original vesting and issuance schedule set forth above, but if and only if such delay in the issuance of the Stock is necessary to avoid the imposition of adverse taxation on you in
respect of the Stock under Section 409A of the Code. Each installment of RSUs that vests, and the issuance of Stock or other payment thereby, is intended to constitute a “separate payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2).
