 Exhibit 10.13 

IMAGO BIOSCIENCES, INC. 

CHANGE IN CONTROL AND SEVERANCE AGREEMENT 

This Change in Control and Severance Agreement (the “Agreement”) is made and entered into by and between
[            ] (“Executive”) and Imago BioSciences, Inc. (the “Company”). This Agreement shall become effective as of the closing of
the initial public offering of the Company’s common stock (the “Effective Date”). 
 R E
C I T A L S 
 A.    The Board of Directors of the Company (the “Board”) recognizes that the
possibility of an acquisition of the Company or an involuntary termination can be a distraction to Executive and can cause Executive to consider alternative employment opportunities. The Board has determined that it is in the best interests of the
Company and its stockholders to assure that the Company will have the continued dedication and objectivity of Executive, notwithstanding the possibility, threat or occurrence of such an event. 

B.    The Board believes that it is in the best interests of the Company and its stockholders to provide Executive with an
incentive to continue Executive’s employment and to motivate Executive to maximize the value of the Company upon a Change in Control (as defined below) for the benefit of its stockholders. 

C.    The Board believes that it is imperative to provide Executive with severance benefits upon certain terminations of
Executive’s service to the Company that enhance Executive’s financial security and provide incentive and encouragement to Executive to remain with the Company notwithstanding the possibility of such an event. 

D.     Unless otherwise defined herein, capitalized terms used in this Agreement are defined in Section 9 below. 

The parties hereto agree as follows: 

1.    Term of Agreement. This Agreement shall become effective as of the Effective Date and terminate upon the date that all
obligations of the parties hereto with respect to this Agreement have been satisfied. 

2.    At-Will Employment. The Company and Executive acknowledge that Executive’s
employment is and shall continue to be “at-will,” as defined under applicable law. If Executive’s employment terminates for any reason, Executive shall not be entitled to any payments, benefits,
damages, awards or compensation other than as provided by this Agreement. 












 3.    Covered Termination Other Than During a Change in Control Period. If
Executive experiences a Covered Termination other than during a Change in Control Period, and if Executive delivers to the Company a general release of all claims against the Company and its affiliates (a “Release

Termination, then in addition to any accrued but unpaid salary, bonus, benefits, vacation and expense reimbursement payable in accordance with applicable law, the Company shall provide Executive with the following: 

(a)    Severance. Executive shall be entitled to receive a severance payment equal to [twelve (12) OR nine (9) OR
six (6)]1 months of Executive’s base salary at the rate in effect immediately prior to the Termination Date payable in a cash lump sum, less applicable withholdings, on the first payroll date
following the date the Release of Claims becomes effective and irrevocable. 
 (b)    Continued Healthcare. If
Executive elects to receive continued healthcare coverage pursuant to the provisions of the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), the Company shall directly pay, or reimburse Executive
for, the premium for Executive and Executive’s covered dependents during the period (the “Non-CIC COBRA Period”) from the Termination Date through the earlier of (i) the
[twelve (12) OR nine (9) OR six (6)]2 month anniversary of the Termination Date and (ii) the date Executive and Executive’s covered dependents, if any, become eligible for healthcare

(or remaining portion thereof). After the Company ceases to pay or reimburse premiums pursuant to the preceding sentence, Executive may, if eligible, elect to continue healthcare coverage at Executive’s expense in accordance the provisions of
COBRA. 
 [CFO only: (c)    Accelerated Vesting. The vesting and, if applicable, exercisability of each unvested

resigned from all offices and directorships, if any, and then held with the Company or any of its affiliates, and, at the Company’s request, Executive shall execute such documents as are necessary or desirable to effectuate such resignations.

 7.    Other Terminations. If Executive’s service with the Company is terminated by the Company or by Executive for any or
no reason other than as a Covered Termination, then Executive shall not be entitled to any benefits hereunder other than accrued but unpaid salary, bonus, vacation and expense reimbursement in accordance with applicable law and to elect any
continued healthcare coverage as may be required under COBRA or similar state law. 
 8.    Limitation on Payments.
Notwithstanding anything in this Agreement to the contrary, if any payment or distribution Executive would receive pursuant to this Agreement or otherwise (“Payment”) would (a) constitute a “parachute payment”
within the meaning of Section 280G of the Code and (b) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall either be
(i) delivered in full, or (ii) delivered as to such lesser extent which would result in no portion of such Payment being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and
local income taxes and the Excise Tax, results in the receipt by Executive on an after-tax basis, of the largest payment, notwithstanding that all or some portion the Payment may be taxable under
Section 4999 of the Code. The accounting firm engaged by the Company for general audit purposes as of the day prior to the effective date of the Change in Control shall perform the foregoing calculations. The Company shall bear all expenses
with respect to the determinations by such accounting firm required to be made hereunder. The accounting firm shall provide its calculations to the Company and Executive within fifteen (15) calendar days after the date on which Executive’s
right to a Payment is triggered (if requested at that time by the Company or Executive) or such other time as requested by the Company or Executive. Any good faith determinations of the accounting firm made hereunder shall be final, binding and
conclusive upon the Company and Executive. Any reduction in payments and/or benefits pursuant to this Section 8 will occur in the following order: (1) reduction of cash payments; (2) cancellation of accelerated vesting of equity

 13.    Dispute Resolution. To ensure the timely and economical resolution of
disputes that arise in connection with this Agreement, Executive and the Company agree that any and all disputes, claims, or causes of action arising from or relating to the enforcement, breach, performance or interpretation of this Agreement,
Executive’s employment, or the termination of Executive’s employment, shall be resolved to the fullest extent permitted by law by final, binding and confidential arbitration in San Francisco County, California through Judicial
Arbitration & Mediation Services/Endispute (“JAMS”) in conformity with the then-existing JAMS employment arbitration rules and California law. A link to the current JAMS employment arbitration rules follows:
https://www.jamsadr.com/rules-employment-arbitration/english. By agreeing to this arbitration procedure, both Executive and the Company waive the right to resolve any such dispute through a trial by jury or judge or administrative
proceeding. The arbitrator shall: (a) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and (b) issue a written arbitration decision, to
include the arbitrator’s essential findings and conclusions and a statement of the award. The Company shall pay all JAMS’s arbitration fees in excess of the amount of court fees that would be required if the dispute were decided in a court
of law. Nothing in this Agreement is intended to prevent either Executive or the Company from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. Notwithstanding the foregoing, Executive
and the Company each have the right to resolve any issue or dispute over intellectual property rights by Court action instead of arbitration. 

14.    Miscellaneous Provisions. 

(a)    Section 409A. 

(i)    Separation from Service. Notwithstanding any provision to the contrary in this Agreement, no amount deemed
deferred compensation subject to Section 409A of the Code shall be payable pursuant to Sections 3 or 4 above unless Executive’s termination of employment constitutes a “separation from service” with the Company within the meaning
of Section 409A of the Code and the Department of Treasury regulations and other guidance promulgated thereunder (“Separation from Service”) and, except as provided under Section 14(a)(ii) of this Agreement, any such
amount shall not be paid, or in the case of installments, commence payment, until the sixtieth (60th) day following Executive’s Separation from Service. Any installment payments that would
have been made to Executive during the sixty (60) day period immediately following Executive’s Separation from Service but for the preceding sentence shall be paid to Executive on the sixtieth (60th) day following Executive’s Separation from Service and the remaining payments shall be made as provided in this Agreement. 

(ii)    Specified Employee. Notwithstanding any provision to the contrary in this Agreement, if Executive is deemed
at the time of Executive’s separation from service to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code, to the extent delayed commencement of any portion of the benefits to which Executive is
entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, such portion of Executive’s benefits shall not be provided to Executive prior to the earlier of (A) the
expiration of the six (6)-month period measured from the date of Executive’s Separation from Service or (B) the date of Executive’s death. Upon the first business day following the expiration of the applicable Code
Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this Section 14(a)(ii) shall be paid in a lump sum to Executive, and any remaining payments due under this Agreement shall be paid as otherwise provided herein.

Executive’s right to reimbursement under this Agreement will not be subject to liquidation or exchange for another benefit. 

(iv)    Installments. For purposes of Section 409A of the Code (including, without limitation, for purposes of
Treasury Regulation Section 1.409A-2(b)(2)(iii)), Executive’s right to receive any installment payments under this Agreement shall be treated as a right to receive a series of separate payments and,
accordingly, each such installment payment shall at all times be considered a separate and distinct payment. 

(b)    Waiver. No provision of this Agreement shall be modified, waived or discharged unless the modification,
waiver or discharge is agreed to in writing and signed by Executive and by an authorized officer of the Company (other than Executive). No waiver by either party of any breach of, or of compliance with, any condition or provision of this Agreement
by the other party shall be considered a waiver of any other condition or provision or of the same condition or provision at another time. 

(c)    Whole Agreement. This Agreement and the Confidential Information Agreement represent the entire
understanding of the parties hereto with respect to the subject matter hereof and supersede all prior promises, arrangements and understandings regarding same, whether written or written, including, without limitation, any severance or change in
control benefits in Executive’s offer letter agreement or employment agreement or previously approved by the Board. 

(d)    Choice of Law. The validity, interpretation, construction and performance of this Agreement shall be
governed by the laws of the state of Delaware. 
 (e)    Severability. The invalidity or unenforceability of any
provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision hereof, which shall remain in full force and effect.
