 Exhibit 10.11 

INDEMNIFICATION AND ADVANCEMENT AGREEMENT 

This Indemnification and Advancement Agreement (“Agreement”) is made as of
                    , 2021 by and between Imago BioSciences, Inc., a Delaware corporation (the “Company”), and
                    , [a member of the Board of Directors / an officer] of the Company (“Indemnitee”). This Agreement supersedes and
replaces any and all previous Agreements between the Company and Indemnitee covering indemnification and advancement. 
 RECITALS 

WHEREAS, the Board of Directors of the Company (the “Board”) believes that highly competent persons have become more reluctant to
serve publicly-held corporations as directors, officers, or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification and advancement of expenses against inordinate risks of claims and
actions against them arising out of their service to and activities on behalf of the corporation; 
 WHEREAS, the Board has determined that,
in order to attract and retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although
the furnishing of such insurance has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be
available to it in the future only at higher premiums and with more exclusions. At the same time, directors, officers, and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and
time-consuming litigation relating to, among other things, matters that traditionally would have been brought only against the Company or business enterprise itself. The Bylaws and Certificate of Incorporation of the Company require indemnification
of the officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware (the “DGCL”). The Bylaws, Certificate of Incorporation, and the DGCL
expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the board of directors, officers and other persons with respect
to indemnification and advancement of expenses; 
 WHEREAS, the uncertainties relating to such insurance, to indemnification, and to
advancement of expenses may increase the difficulty of attracting and retaining such persons; 
 WHEREAS, the Board has determined that the
increased difficulty in attracting and retaining such persons is detrimental to the best interests of the Company and its stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection
in the future; 
 WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to
advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

  
 1 













 WHEREAS, this Agreement is a supplement to and in furtherance of the Bylaws, Certificate of
Incorporation and any resolutions adopted pursuant thereto, and is not a substitute therefor, nor diminishes or abrogates any rights of Indemnitee thereunder; and 

WHEREAS, Indemnitee does not regard the protection available under the Bylaws, Certificate of Incorporation, DGCL and insurance as adequate in
the present circumstances, and may not be willing to serve or continue to serve as an officer or director without adequate additional protection, and the Company desires Indemnitee to serve or continue to serve in such capacity. Indemnitee is
willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that Indemnitee be so indemnified and be advanced expenses. 

NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree
as follows: 
 Section 1.    Services to the Company. Indemnitee agrees to serve as a [director/officer] of
the Company. Indemnitee may at any time and for any reason resign from such position (subject to any other contractual obligation or any obligation imposed by operation of law). This Agreement does not create any obligation on the Company to
continue Indemnitee in such position and is not an employment contract between the Company (or any of its subsidiaries or any Enterprise) and Indemnitee. 

Section 2.    Definitions. As used in this Agreement: 

(a)    “Agent” means any person who is authorized by the Company or an Enterprise to act for or represent the
interests of the Company or an Enterprise, respectively. 
 (b)    A “Change in Control” occurs upon the

Third Party. Any Person (as defined below) is or becomes the Beneficial Owner (as defined below), directly or indirectly, of securities of the Company representing fifteen percent (15%) or more of the combined voting power of the Company’s then
outstanding securities unless the change in relative beneficial ownership of the Company’s securities by any Person results solely from a reduction in the aggregate number of outstanding shares of securities entitled to vote generally in the
election of directors; 
 ii.    Change in Board of Directors. During any period of two (2) consecutive years (not
including any period prior to the execution of this Agreement), individuals who at the beginning of such period constitute the Board, and any new director (other than a director designated by a person who has entered into an agreement with the
Company to effect a transaction described in Sections 2(b)(i), 2(b)(iii) or 2(b)(iv)) whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least
two-thirds of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to
constitute at least a majority of the members of the Board; 

  
 2 













 iii.    Corporate Transactions. The effective date of a merger or
consolidation of the Company with any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by

with the power to elect at least a majority of the board of directors or other governing body of such surviving entity; 

iv.    Liquidation. The approval by the stockholders of the Company of a complete liquidation of the Company or an

Company in substantially the same proportions as their ownership of stock of the Company.

enforcement or defense of Indemnitee’s rights under this Agreement, by litigation or otherwise. The parties agree that for the purposes of any advancement of Expenses for which Indemnitee has made written demand to the Company in accordance
with this Agreement, all Expenses included in such demand that are certified by affidavit of Indemnitee’s counsel as being reasonable in the good faith judgment of such counsel will be presumed conclusively to be reasonable. Expenses, however,
do not include amounts paid in settlement by Indemnitee or the amount of judgments or fines against Indemnitee. 

(g)    “Independent Counsel” means a law firm, or a member of a law firm, that is experienced in matters of

or completed action, suit, claim, counterclaim, cross claim, arbitration, mediation, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought in
the right of the Company or otherwise and whether of a civil, criminal, administrative, legislative, or investigative (formal or informal) nature, including any appeal therefrom, in which Indemnitee was, is or will be involved as a party, potential
party, non-party witness or otherwise by reason of Indemnitee’s Corporate Status or by reason of any action taken by Indemnitee (or a failure to take action by Indemnitee) or of any action (or failure to
act) on Indemnitee’s part while acting pursuant to Indemnitee’s Corporate Status, in each case whether or not serving in such capacity at the time any liability or Expense is incurred for which indemnification, reimbursement, or
advancement of Expenses can be provided under this Agreement. A Proceeding also includes a situation the Indemnitee believes in good faith may lead to or culminate in the institution of a Proceeding. 

Section 3.    Indemnity in Third-Party Proceedings. The Company will indemnify Indemnitee in accordance with
the provisions of this Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this
Section 3, the Company will indemnify Indemnitee to the fullest extent permitted by applicable law against all Expenses, judgments, fines and amounts paid in settlement (including all interest, assessments and other charges paid or payable in
connection with or in respect of such Expenses, judgments, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein,
if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company and, in the case of a criminal Proceeding had no reasonable cause to believe that Indemnitee’s conduct
was unlawful. 
 Section 4.    Indemnity in Proceedings by or in the Right of the Company. The Company will
indemnify Indemnitee in accordance with the provisions of this Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant
to this Section 4, the Company will indemnify Indemnitee to the fullest extent permitted by applicable law against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or
any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. The Company will not indemnify Indemnitee for Expenses under this
Section 4 related to any claim, issue or matter in a Proceeding for which Indemnitee has been finally adjudged by a court to be liable to the Company, unless, and only to the extent that, the Delaware Court of Chancery or any court in which the
Proceeding was brought determines upon application by Indemnitee that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification. 

Section 5.    Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any
other provisions of this Agreement, to the fullest extent permitted by applicable law, the Company will indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee in connection with any Proceeding the extent that
Indemnitee is successful, on the merits or otherwise. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all 

  
 5 













 
claims, issues or matters in such Proceeding, the Company will indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in
connection with or related to each successfully resolved claim, issue or matter to the fullest extent permitted by law. For purposes of this Section 5 and without limitation, the termination of any claim, issue or matter in such a Proceeding by
dismissal, with or without prejudice, will be deemed to be a successful result as to such claim, issue or matter. 

Section 6.    Indemnification For Expenses of a Witness. Notwithstanding any other provision of this Agreement
and to the fullest extent permitted by applicable law, the Company will indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with any Proceeding to which Indemnitee is
not a party but to which Indemnitee is a witness, deponent, interviewee, or otherwise asked to participate. 

Section 7.    Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to
indemnification by the Company for some or a portion of Expenses, but not, however, for the total amount thereof, the Company will indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. 

Section 8.    Additional Indemnification. Notwithstanding any limitation in Sections 3, 4, or 5, the Company
will indemnify Indemnitee to the fullest extent permitted by applicable law (including but not limited to, the DGCL and any amendments to or replacements of the DGCL adopted after the date of this Agreement that expand the Company’s ability to
indemnify its officers and directors) if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor). 

Section 9.    Exclusions. Notwithstanding any provision in this Agreement, the Company is not obligated under
this Agreement to make any indemnification payment to Indemnitee in connection with any Proceeding: 
 (a)    for which
payment has actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except to the extent provided in Section 16(b) of the Exchange Act (as defined in Section 2(b) hereof) and except with
respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; or 
 (b)    for
(i) an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act or similar provisions of state statutory law or common
law, (ii) any reimbursement of the Company by the Indemnitee of any bonus or other incentive-based or equity-based compensation or of any profits realized by the Indemnitee from the sale of securities of the Company, as required in each case
under the Exchange Act (including any such reimbursements that arise from an accounting restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment to the Company of
profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act) or (iii) any reimbursement of the Company by Indemnitee of any compensation pursuant to any compensation
recoupment or clawback policy adopted by the Board or the compensation committee of the Board, including but not limited to any such policy adopted to comply with stock exchange listing requirements implementing Section 10D of the Exchange Act;
or 

  
 6 













 (c)    initiated by Indemnitee, including any Proceeding (or any part of
any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Proceeding or part of any Proceeding is to enforce Indemnitee’s rights to indemnification or
advancement, of Expenses, including a Proceeding (or any part of any Proceeding) initiated pursuant to Section 14 of this Agreement, (ii) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation or
(iii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law. 

Section 10.    Advances of Expenses. 

(a)    The Company will advance, to the extent not prohibited by law, the Expenses incurred by Indemnitee in connection
with any Proceeding (or any part of any Proceeding) not initiated by Indemnitee or any Proceeding (or any part of any Proceeding) initiated by Indemnitee if (i) the Proceeding or part of any Proceeding is to enforce Indemnitee’s rights to
obtain indemnification or advancement of Expenses from the Company or Enterprise, including a proceeding initiated pursuant to Section 14 or (ii) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation.
The Company will advance the Expenses within thirty (30) days after the receipt by the Company of a statement or statements requesting such advances from time to time, whether prior to or after final disposition of any Proceeding. 

(b)    Advances will be unsecured and interest free. Indemnitee undertakes to repay the amounts advanced (without
interest) to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company, thus Indemnitee qualifies for advances upon the execution of this Agreement and delivery to the Company. No other form of
undertaking is required other than the execution of this Agreement. The Company will make advances without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to indemnification
under the other provisions of this Agreement. 
 Section 11.    Procedure for Notification of Claim for
Indemnification or Advancement. 
 (a)    Indemnitee will notify the Company in writing of any Proceeding with
respect to which Indemnitee intends to seek indemnification or advancement of Expenses hereunder as soon as reasonably practicable following the receipt by Indemnitee of written notice thereof. Indemnitee will include in the written notification to
the Company a description of the nature of the Proceeding and the facts underlying the Proceeding and provide such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what
extent Indemnitee is entitled to indemnification following the final disposition of such Proceeding. Indemnitee’s failure to notify the Company will not relieve the Company from any obligation it may have to Indemnitee under this Agreement, and
any delay in so notifying the Company will not constitute a waiver by Indemnitee of any rights under this Agreement. The Secretary of the Company will, promptly upon receipt of such a request for indemnification or advancement, advise the Board in
writing that Indemnitee has requested indemnification or advancement. 

  
 7 













 (b)    The Company will be entitled to participate in the Proceeding at
its own expense. 
 Section 12.    Procedure Upon Application for Indemnification. 

(a)    Unless a Change of Control has occurred, the determination of Indemnitee’s entitlement to indemnification will
be made: 
 i.    by a majority vote of the Disinterested Directors, even though less than a quorum of the Board; 

ii.    by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even
though less than a quorum of the Board; 
 iii.     if there are no such Disinterested Directors or, if such
Disinterested Directors so direct, by written opinion provided by Independent Counsel selected by the Board; or 

iv.    if so directed by the Board, by the stockholders of the Company. 

(b)    If a Change in Control has occurred, the determination of Indemnitee’s entitlement to indemnification will be
made by written opinion provided by Independent Counsel selected by Indemnitee (unless Indemnitee requests such selection be made by the Board). 

(c)     The party selecting Independent Counsel pursuant to subsection (a)(iii) or (b) of this Section 12 will
provide written notice of the selection to the other party. The notified party may, within ten (10) days after receiving written notice of the selection of Independent Counsel, deliver to the selecting party a written objection to such
selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 2 of this
Agreement, and the objection will set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected will act as Independent Counsel. If such written objection is so made and substantiated,
the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or the Delaware Court has determined that such objection is without merit. If, within thirty (30) days after the later of
submission by Indemnitee of a written request for indemnification pursuant to Section 11(a) hereof and the final disposition of the Proceeding, Independent Counsel has not been selected or, if selected, any objection to has not been resolved,
either the Company or Indemnitee may petition the Delaware Court for the appointment as Independent Counsel of a person selected by such court or by such other person as such court designates. Upon the due commencement of any judicial proceeding or
arbitration pursuant to Section 14(a) of this Agreement, Independent Counsel will be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 

  
 8 













 (d)    Indemnitee will cooperate with the person, persons or entity
making the determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise
protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. The Company will advance and pay any Expenses incurred by Indemnitee in so cooperating with the person, persons or entity
making the indemnification determination irrespective of the determination as to Indemnitee’s entitlement to indemnification and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. The Company promptly will advise
Indemnitee in writing of the determination that Indemnitee is or is not entitled to indemnification, including a description of any reason or basis for which indemnification has been denied and providing a copy of any written opinion provided to the
Board by Independent Counsel. 
 (e)    If it is determined that Indemnitee is entitled to indemnification, the Company
will make payment to Indemnitee within ten (10) days after such determination. 

Section 13.    Presumptions and Effect of Certain Proceedings. 

(a)    In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity
making such determination will, to the fullest extent not prohibited by law, presume Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 11(a) of
this Agreement, and the Company will, to the fullest extent not prohibited by law, have the burden of proof to overcome that presumption. Neither the failure of the Company (including by its directors or Independent Counsel) to have made a
determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including
by its directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, will be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(b)    If the determination of the Indemnitee’s entitlement to indemnification has not made pursuant to
Section 12 within sixty (60) days after the later of (i) receipt by the Company of Indemnitee’s request for indemnification pursuant to Section 11(a) and (ii) the final disposition of the Proceeding for which Indemnitee
requested Indemnification (the “Determination Period”), the requisite determination of entitlement to indemnification will, to the fullest extent not prohibited by law, be deemed to have been made and Indemnitee will be entitled to such
indemnification, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or
(ii) a prohibition of such indemnification under applicable law. The Determination Period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making the determination with
respect to entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto; and provided, further, the Determination Period may be extended an additional
fifteen (15) days if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 12(a)(iv) of this Agreement. 

  
 9 













 (c)    The termination of any Proceeding or of any claim, issue or
matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, will not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee
to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that
Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful. 
 (d)    For purposes of any
determination of good faith, Indemnitee will be deemed to have acted in good faith if Indemnitee acted based on the records or books of account of the Company, its subsidiaries, or an Enterprise, including financial statements, or on information
supplied to Indemnitee by the directors or officers of the Company, its subsidiaries, or an Enterprise in the course of their duties, or on the advice of legal counsel for the Company, its subsidiaries, or an Enterprise or on information or records
given or reports made to the Company or an Enterprise by an independent certified public accountant or by an appraiser, financial advisor or other expert selected with reasonable care by or on behalf of the Company, its subsidiaries, or an
Enterprise. Further, Indemnitee will be deemed to have acted in a manner “not opposed to the best interests of the Company,” as referred to in this Agreement if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed
to be in the best interests of the participants and beneficiaries of an employee benefit plan. The provisions of this Section 13(d) is not exclusive and does not limit in any way the other circumstances in which the Indemnitee may be deemed to
have met the applicable standard of conduct set forth in this Agreement. 
 (e)    The knowledge and/or actions, or
failure to act, of any director, officer, trustee, partner, managing member, fiduciary, agent or employee of the Enterprise may not be imputed to Indemnitee for purposes of determining Indemnitee’s right to indemnification under this Agreement.

 Section 14.    Remedies of Indemnitee. 

(a)    Indemnitee may commence litigation against the Company in the Delaware Court of Chancery to obtain indemnification
or advancement of Expenses provided by this Agreement in the event that (i) a determination is made pursuant to Section 12 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) the Company
does not advance Expenses pursuant to Section 10 of this Agreement, (iii) the determination of entitlement to indemnification is not made pursuant to Section 12 of this Agreement within the Determination Period, (iv) the Company
does not indemnify Indemnitee pursuant to Section 5 or 6 or the second to last sentence of Section 12(d) of this Agreement within ten (10) days after receipt by the Company of a written request therefor, (v) the Company does not
indemnify Indemnitee pursuant to Section 3, 4, 7, or 8 of this Agreement within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification, or (vi) in the event that the Company or any other
person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or Proceeding designed to deny, or to recover from, the 

  
 10 













 
Indemnitee the benefits provided or intended to be provided to the Indemnitee hereunder. Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in arbitration to be conducted
by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee must commence such Proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which
Indemnitee first has the right to commence such Proceeding pursuant to this Section 14(a); provided, however, that the foregoing clause does not apply in respect of a Proceeding brought by Indemnitee to enforce Indemnitee’s
rights under Section 5 of this Agreement. The Company will not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 

(b)    If a determination is made pursuant to Section 12 of this Agreement that Indemnitee is not entitled to
indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 14 will be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee may not be prejudiced by reason of that
adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section 14 the Company will have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be and
will not introduce evidence of the determination made pursuant to Section 12 of this Agreement. 
 (c)    If a
determination is made pursuant to Section 12 of this Agreement that Indemnitee is entitled to indemnification, the Company will be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 14,
absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a
prohibition of such indemnification under applicable law. 
 (d)    The Company is, to the fullest extent not prohibited
by law, precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 14 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and will stipulate in any such court
or before any such arbitrator that the Company is bound by all the provisions of this Agreement. 
 (e)    It is the
intent of the Company that, to the fullest extent permitted by law, the Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by
litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to the Indemnitee hereunder. The Company, to the fullest extent permitted by law, will (within ten (10) days
after receipt by the Company of a written request therefor) advance to Indemnitee such Expenses which are incurred by Indemnitee in connection with any action concerning this Agreement, Indemnitee’s right to indemnification or advancement of
Expenses from the Company, or concerning any directors’ and officers’ liability insurance policies maintained by the Company, and will indemnify Indemnitee against any and all such Expenses unless the court determines that each of the
Indemnitee’s claims in such Proceeding were made in bad faith or were frivolous or are prohibited by law.

 Section 15.    Establishment of Trust. 

(a)    In the event of a Potential Change in Control or a Change in Control, the Company will, upon written request by
Indemnitee, create a trust for the benefit of Indemnitee (the “Trust”) and from time to time upon written request of Indemnitee will fund such Trust in an amount sufficient to satisfy the reasonably anticipated indemnification and
advancement obligations of the Company to the Indemnitee in connection with any Proceeding for which Indemnitee has demanded indemnification and/or advancement prior to the Potential Change in Control or Change in Control (the “Funding
Obligation”). The trustee of the Trust (the “Trustee”) will be a bank or trust company or other individual or entity chosen by the Indemnitee and reasonably acceptable to the Company. Nothing in this Section 15 relieves the
Company of any of its obligations under this Agreement. 
 (b)    The amount or amounts to be deposited in the Trust
pursuant to the Funding Obligation will be determined by mutual agreement of the Indemnitee and the Company or, if the Company and the Indemnitee are unable to reach such an agreement, by Independent Counsel selected in accordance with
Section 12(b) of this Agreement. The terms of the Trust will provide that, except upon the consent of both the Indemnitee and the Company, upon a Change in Control: (i) the Trust may not be revoked, or the principal thereof invaded,
without the written consent of the Indemnitee; (ii) the Trustee will advance Expenses incurred by Indemnitee, to the fullest extent permitted by applicable law, within two (2) business days of a request by the Indemnitee; (iii) the
Company will continue to fund the Trust in accordance with the Funding Obligation; (iv) the Trustee will promptly pay to the Indemnitee all amounts for which the Indemnitee is entitled to indemnification pursuant to this Agreement or otherwise;
and (v) all unexpended funds in such Trust revert to the Company upon mutual agreement by the Indemnitee and the Company or, if the Indemnitee and the Company are unable to reach such an agreement, by Independent Counsel selected in accordance
with Section 12(b) of this Agreement, that the Indemnitee has been fully indemnified under the terms of this Agreement. New York law (without regard to its conflicts of laws rules) governs the Trust and the Trustee will consent to the exclusive
jurisdiction of Delaware Court of Chancery, in accordance with Section 25 of this Agreement. 

Section 16.    Non-exclusivity; Survival of Rights; Insurance;
Subrogation. 
 (a)    The indemnification and advancement of Expenses provided by this Agreement are not exclusive
of any other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders or a resolution of directors, or otherwise. The indemnification and
advancement of Expenses provided by this Agreement may not be limited or restricted by any amendment, alteration or repeal of this Agreement in any way with respect to any action taken or omitted by Indemnitee in Indemnitee’s Corporate Status
occurring prior to any amendment, alteration or repeal of this Agreement. To the extent that a change in Delaware law, whether by statute or judicial decision, permits greater indemnification or advancement of Expenses than would be afforded
currently under the Bylaws, Certificate of Incorporation, or this Agreement, it is the intent of the parties hereto that Indemnitee enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is
intended to be exclusive of any other right or remedy, and every other right and remedy is cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, will not prevent the concurrent assertion or employment of any other right or remedy.

 (b)    The Company hereby acknowledges that Indemnitee may have certain
rights to indemnification, advancement of Expenses and/or insurance provided by one or more Persons with whom or which Indemnitee may be associated [(including, without limitation, [Entity] and certain of its affiliates, collectively, the
“Entity Indemnitors”)]). 
 i.    The Company hereby acknowledges and agrees: 

1)    the Company is the indemnitor of first resort with respect to any request for indemnification or advancement of
Expenses made pursuant to this Agreement concerning any Proceeding arising from or related to Indemnitee’s Corporate Status with the Company; 

2)     the Company is primarily liable for all indemnification and indemnification or advancement of Expenses obligations
for any Proceeding arising from or related to Indemnitee’s Corporate Status, whether created by law, organizational or constituent documents, contract (including this Agreement) or otherwise; 

3)    any obligation of any other Persons with whom or which Indemnitee may be associated [(including, without
limitation, any Entity Indemnitor)] to indemnify Indemnitee and/or advance Expenses to Indemnitee in respect of any proceeding are secondary to the obligations of the Company’s obligations; 

4)    the Company will indemnify Indemnitee and advance Expenses to Indemnitee hereunder to the fullest extent provided
herein without regard to any rights Indemnitee may have against any other Person with whom or which Indemnitee may be associated [(including any Entity Indemnitor)] or insurer of any such Person; and 

ii.    the Company irrevocably waives, relinquishes and releases [(A)] any other Person with whom or which Indemnitee may
be associated [(including, without limitation, any Entity Indemnitor)] from any claim of contribution, subrogation, reimbursement, exoneration or indemnification, or any other recovery of any kind in respect of amounts paid by the Company to
Indemnitee pursuant to this Agreement [and (B) any right to participate in any claim or remedy of Indemnitee against any Entity Indemnitor (or former Entity Indemnitor)], whether or not such claim, remedy or right arises in equity or under
contract, statute or common law[, including, without limitation, the right to take or receive from any Entity Indemnitor (or former Entity Indemnitor), directly or indirectly, in cash or other property or by
set-off or in any other manner, payment or security on account of such claim, remedy or right]. 

iii.    In the event any other Person with whom or which Indemnitee may be associated [(including, without limitation,
any Entity Indemnitor)] or their insurers advances or extinguishes any liability or loss for Indemnitee, the payor has a right of subrogation against the Company or its insurers for all amounts so paid which would otherwise be payable by the Company
or its insurers under this Agreement. In no event will payment by any other Person with whom or which Indemnitee may be associated [(including, without limitation, any Entity Indemnitor)] or 

  
 13 













 
their insurers affect the obligations of the Company hereunder or shift primary liability for the Company’s obligation to indemnify or advance of Expenses to any other Person with whom or
which Indemnitee may be associated [(including, without limitation, any Entity Indemnitor)]. 
 iv.    Any
indemnification or advancement of Expenses provided by any other Person with whom or which Indemnitee may be associated [(including, without limitation, any Entity Indemnitor)] is specifically in excess over the Company’s obligation to
indemnify and advance Expenses or any valid and collectible insurance (including but not limited to any malpractice insurance or professional errors and omissions insurance) provided by the Company. 

(c)    To the extent that the Company maintains an insurance policy or policies providing liability insurance for
directors, officers, employees, or agents of the Enterprise, the Company will obtain a policy or policies covering Indemnitee to the maximum extent of the coverage available for any such director, officer, employee or agent under such policy or
policies, including coverage in the event the Company does not or cannot, for any reason, indemnify or advance Expenses to Indemnitee as required by this Agreement. If, at the time of the receipt of a notice of a claim pursuant to this Agreement,
the Company has director and officer liability insurance in effect, the Company will give prompt notice of such claim or of the commencement of a Proceeding, as the case may be, to the insurers in accordance with the procedures set forth in the
respective policies. The Company will thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies.
Indemnitee agrees to assist the Company efforts to cause the insurers to pay such amounts and will comply with the terms of such policies, including selection of approved panel counsel, if required. 

(d)    The Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee for any Proceeding
concerning Indemnitee’s Corporate Status with an Enterprise will be reduced by any amount Indemnitee has actually received as indemnification or advancement of Expenses from such Enterprise. The Company and Indemnitee intend that any such
Enterprise (and its insurers) be the indemnitor of first resort with respect to indemnification and advancement of Expenses for any Proceeding related to or arising from Indemnitee’s Corporate Status with such Enterprise. The Company’s
obligation to indemnify and advance Expenses to Indemnitee is secondary to the obligations the Enterprise or its insurers owe to Indemnitee. Indemnitee agrees to take all reasonably necessary and desirable action to obtain from an Enterprise
indemnification and advancement of Expenses for any Proceeding related to or arising from Indemnitee’s Corporate Status with such Enterprise. 

(e)    In the event of any payment made by the Company under this Agreement, the Company will be subrogated to the extent
of such payment to all of the rights of recovery of Indemnitee from any Enterprise or insurance carrier. Indemnitee will execute all papers required and take all action necessary to secure such rights, including execution of such documents as are
necessary to enable the Company to bring suit to enforce such rights. 
 Section 17.    Duration of
Agreement. This Agreement continues until and terminates upon the later of: (a) ten (10) years after the date that Indemnitee ceases to serve as a [director / officer] of the Company or (b) one (1) year after the final termination of
any Proceeding then 

  
 14 













 
pending in respect of which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any Proceeding commenced by Indemnitee pursuant to Section 14 of this
Agreement relating thereto. The indemnification and advancement of Expenses rights provided by or granted pursuant to this Agreement are binding upon and be enforceable by the parties hereto and their respective successors and assigns (including any
direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the
Company or of any other Enterprise, and inure to the benefit of Indemnitee and Indemnitee’s spouse, assigns, heirs, devisees, executors and administrators and other legal representatives. 

Section 18.    Severability. If any provision or provisions of this Agreement is held to be invalid, illegal
or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any section of this Agreement containing any such provision
held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) will not in any way be affected or impaired thereby and remain enforceable to the fullest extent permitted by law; (b) such provision or
provisions will be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement (including,
without limitation, each portion of any section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) will be construed so as to give effect to the intent
manifested thereby. 
 Section 19.    Interpretation. Any ambiguity in the terms of this Agreement will be
resolved in favor of Indemnitee and in a manner to provide the maximum indemnification and advancement of Expenses permitted by law. The Company and Indemnitee intend that this Agreement provide to the fullest extent permitted by law for
indemnification and advancement in excess of that expressly provided, without limitation, by the Certificate of Incorporation, the Bylaws, vote of the Company stockholders or disinterested directors, or applicable law. 

Section 20.    Enforcement. 

(a)    The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations
imposed on it hereby in order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving or continuing to serve as a director or officer of the
Company. 
 (b)    This Agreement constitutes the entire agreement between the parties hereto with respect to the
subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in
furtherance of the Certificate of Incorporation, the Bylaws and applicable law, and is not a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 

  
 15 













 Section 21.    Modification and Waiver. No supplement,
modification or amendment of this Agreement is binding unless executed in writing by the parties hereto. No waiver of any of the provisions of this Agreement will be deemed or constitutes a waiver of any other provisions of this Agreement nor will
any waiver constitute a continuing waiver. 
 Section 22.    Notice by Indemnitee. Indemnitee agrees
promptly to notify the Company in writing upon being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advancement of
Expenses covered hereunder. The failure of Indemnitee to so notify the Company does not relieve the Company of any obligation which it may have to the Indemnitee under this Agreement or otherwise. 

Section 23.    Notices. All notices, requests, demands and other communications under this Agreement will be
in writing and will be deemed to have been duly given if (a) delivered by hand to the other party, (b) sent by reputable overnight courier to the other party or (c) sent by facsimile transmission or electronic mail, with receipt of
oral confirmation that such communication has been received: 
 (a)    If to Indemnitee, at the address indicated on

 or to any other address as may have been furnished to Indemnitee by the Company. 

Section 24.    Contribution. To the fullest extent permissible under applicable law, if the indemnification
provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, will contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes,
amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such
Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and its
directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 

Section 25.    Applicable Law and Consent to Jurisdiction. This Agreement and the legal relations among the
parties are governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its conflict of laws rules. Except with respect to any arbitration commenced by Indemnitee pursuant to Section 14(a) of
this Agreement, the 

  
 16 













 
Company and Indemnitee hereby irrevocably and unconditionally (i) agree that any action or Proceeding arising out of or in connection with this Agreement may be brought only in the Delaware
Court of Chancery and not in any other state or federal court in the United States of America or any court in any other country, (ii) consent to submit to the exclusive jurisdiction of the Delaware Court for purposes of any action or Proceeding
arising out of or in connection with this Agreement, (iii) waive any objection to the laying of venue of any such action or Proceeding in the Delaware Court, and (iv) waive, and agree not to plead or to make, any claim that any such action
or Proceeding brought in the Delaware Court has been brought in an improper or inconvenient forum. 

Section 26.    Identical Counterparts. This Agreement may be executed in one or more counterparts, each of
which will for all purposes be deemed to be an original but all of which together constitutes one and the same Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the
existence of this Agreement. 
 Section 27.    Headings. The headings of this Agreement are inserted for
convenience only and do not constitute part of this Agreement or affect the construction thereof. 
 IN WITNESS WHEREOF, the parties have
caused this Agreement to be signed as of the day and year first above written.
