EX-10.9




 Exhibit 10.9 

Indemnification Agreement 

This Indemnification Agreement (this “Agreement”) is dated as of [●], 2022, and is between Apexigen, Inc., a
Delaware corporation (the “Company”), and [●], an individual (“Indemnitee”). 

Recitals 

A.    Indemnitee’s service to the Company substantially benefits the Company. 

B.    Individuals are reluctant to serve as directors or officers of corporations or in certain other capacities unless
they are provided with adequate protection through insurance or indemnification against the risks of claims and actions against them arising out of such service. 

C.    Indemnitee does not regard the protection currently provided by applicable law, the Company’s governing
documents and any insurance as adequate under the present circumstances, and Indemnitee may not be willing to serve as a director or officer without additional protection. 

D.    In order to induce Indemnitee to continue to provide services to the Company, it is reasonable, prudent and
necessary for the Company to contractually obligate itself to indemnify, and to advance expenses on behalf of, Indemnitee as permitted by applicable law. 

E.    This Agreement is a supplement to and in furtherance of the indemnification provided in the Company’s
certificate of incorporation and bylaws, and any resolutions adopted pursuant thereto, and this Agreement shall not be deemed a substitute therefor, nor shall this Agreement be deemed to limit, diminish or abrogate any rights of Indemnitee
thereunder. 
 The parties therefore agree as follows: 

1.    Definitions.  

(a)    A “Change in Control” shall be deemed to occur upon the earliest to occur after the date of
this Agreement of any of the following events: 
 (i)    the acquisition of the Company by another entity by means of
any transaction or series of related transactions (including, without limitation, any reorganization, merger or consolidation or stock transfer, but excluding any such transaction effected primarily for the purpose of changing the domicile of the
Company), unless the Company’s stockholders of record immediately prior to such transaction or series of related transactions hold, immediately after such transaction or series of related transactions, at least 50% of the voting power of the
surviving or acquiring entity (provided that the sale by the Company of its securities for the purposes of raising additional funds shall not constitute a Change in Control hereunder); or 











 (ii)    the sale of all or substantially all of the assets of the
Company. 
 (b)    “Corporate Status” describes the status of a person who is or was a director,
trustee, general partner, managing member, officer, employee, agent or fiduciary of the Company or any other Enterprise. 

(c)    “DGCL” means the General Corporation Law of the State of Delaware. 

(d)    “Disinterested Director” means a director of the Company who is not and was not a party to
the Proceeding in respect of which indemnification is sought by Indemnitee. 

(e)    “Enterprise” means the Company and any other corporation, partnership, limited liability
company, joint venture, trust, employee benefit plan or other enterprise of which Indemnitee is or was serving at the request of the Company as a director, trustee, general partner, managing member, officer, employee, agent or fiduciary. 

(f)    “Expenses” include all reasonable attorneys’ fees, retainers, court costs, transcript
costs, fees and costs of experts, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees, and all other disbursements or expenses of the types customarily incurred in
connection with prosecuting, defending, preparing to prosecute or defend, investigating, being or preparing to be a witness in, or otherwise participating in, a Proceeding. Expenses also include (i) Expenses incurred in connection with any
appeal resulting from any Proceeding, including without limitation the premium, security for, and other costs relating to any cost bond, supersedeas bond or other appeal bond or their equivalent, and (ii) for purposes of Section 12(d),
Expenses incurred by Indemnitee in connection with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company.
Expenses, however, shall 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 partner or member of a law firm, that is
experienced in matters of corporation law and neither presently is, nor in the past five years has been, retained to represent (i) the Company or Indemnitee in any matter material to either such party (other than as Independent Counsel with
respect to matters concerning Indemnitee under this Agreement, or other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the
foregoing, the term “Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or
Indemnitee in an action to determine Indemnitee’s rights under this Agreement. 

  
 -2- 












 (h)    “Proceeding” means any threatened,
pending or completed action, suit, arbitration, mediation, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or proceeding, whether brought in the right of the Company or otherwise and whether of a civil,
criminal, administrative or investigative nature, including any appeal therefrom, in which Indemnitee was, is or will be involved as a party, a potential party, a non-party witness or otherwise by reason of
(i) the fact that Indemnitee is or was a director or officer of the Company, (ii) any action taken by Indemnitee or any action or inaction on Indemnitee’s part while acting as a director or officer of the Company, or (iii) the
fact that they are or was serving at the request of the Company as a director, trustee, general partner, managing member, officer, employee, agent or fiduciary of the Company or any other Enterprise, in each case whether or not serving in such
capacity at the time any liability or Expense is incurred for which indemnification or advancement of expenses can be provided under this Agreement. 

(i)    Reference to “other enterprises” shall include employee benefit plans; references to
“fines” shall include any excise taxes assessed on a person with respect to any employee benefit plan; references to “serving at the request of the Company” shall include any service as a director,
officer, employee or agent of the Company which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith
and in a manner they reasonably believed to be in the best interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the
Company” as referred to in this Agreement. 
 2.    Indemnity in Third-Party Proceedings. The
Company shall indemnify Indemnitee in accordance with the provisions of this Section 2 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 2, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses, judgments, fines and amounts paid in settlement actually and reasonably
incurred by Indemnitee or on their behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the
Company and, with respect to any criminal action or proceeding, had no reasonable cause to believe that their conduct was unlawful. 

3.    Indemnity in Proceedings by or in the Right of the Company. The Company shall 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 by or in the right of the Company to procure a judgment in its favor. Pursuant to this Section 3,
Indemnitee shall be indemnified 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 they reasonably believed to be in or not opposed to the best interests of the Company. No indemnification for Expenses shall be made under this Section 3 in respect of any claim,


  
 -3- 












 
issue or matter as to which Indemnitee shall have been adjudged by a court of competent jurisdiction 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 shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification for such
expenses as the Delaware Court of Chancery or such other court shall deem proper. 
 4.    Indemnification for
Expenses of a Party Who is Wholly or Partly Successful. To the extent that Indemnitee is a party to or a participant in and is successful (on the merits or otherwise) in defense of any Proceeding or any claim, issue or matter therein, the
Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. To the extent permitted by applicable law, if Indemnitee is not wholly successful in such
Proceeding but is successful, on the merits or otherwise, in defense of one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by
Indemnitee or on Indemnitee’s behalf in connection with (a) each successfully resolved claim, issue or matter and (b) any claim, issue or matter related to any such successfully resolved claim, issue or matter. For purposes of this
section, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 

5.    Indemnification for Expenses of a Witness. To the extent that Indemnitee is, by reason of their Corporate
Status, a witness in any Proceeding to which Indemnitee is not a party, Indemnitee shall be indemnified to the extent permitted by applicable law against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in
connection therewith. 
 6.    Additional Indemnification. 

(a)    Notwithstanding any limitation in Sections 2, 3 or 4, the Company shall indemnify Indemnitee to the fullest
extent permitted by applicable law if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against all Expenses,
judgments, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee or on their behalf in connection with the Proceeding or any claim, issue or matter therein. 

(b)    For purposes of Section 6(a), the meaning of the phrase “to the fullest extent permitted by
applicable law” shall include, but not be limited to: 
 (i)    the fullest extent permitted by the
provision of the DGCL that authorizes or contemplates additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the DGCL; and 

  
 -4- 












 (ii)    the fullest extent authorized or permitted by any amendments to
or replacements of the DGCL adopted after the date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors. 

7.    Exclusions. Notwithstanding any provision in this Agreement, the Company shall not be obligated under this
Agreement to make any indemnity in connection with any Proceeding (or any part of any Proceeding): 
 (a)    for which
payment has actually been made to or on behalf of Indemnitee under any statute, insurance policy, indemnity provision, vote or otherwise, except with respect to any excess beyond the amount paid; 

(b)    for an accounting or disgorgement of profits pursuant to Section 16(b) of the Securities Exchange Act of 1934,
as amended, or similar provisions of federal, state or local statutory law or common law, if Indemnitee is held liable therefor (including pursuant to any settlement arrangements); 

(c)    for any reimbursement of the Company by Indemnitee of any bonus or other incentive-based or equity-based
compensation or of any profits realized by Indemnitee from the sale of securities of the Company, as required in each case under the Securities Exchange Act of 1934, as amended (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), if Indemnitee is held liable therefor (including pursuant to any settlement arrangements); 

(d)    initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against
the Company or its directors, officers, employees, agents or other indemnitees, unless (i) the Company’s board of directors authorized the Proceeding (or the relevant part of the Proceeding) prior to its initiation, (ii) the Company
provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law, (iii) otherwise authorized in Section 12(d) or (iv) otherwise required by applicable law; or 

(e)    if prohibited by applicable law. 

8.    Advances of Expenses. The Company shall advance the Expenses incurred by Indemnitee in connection with any
Proceeding, and such advancement shall be made as soon as reasonably practicable, but in any event no later than 60 days, after the receipt by the Company of a written statement or statements requesting such advances from time to time (which shall
include invoices received by Indemnitee in connection with such Expenses but, in the case of invoices in connection with legal services, any references to legal work performed or to expenditure made that would cause Indemnitee to waive any privilege
accorded by applicable law shall not be included with the invoice). Advances shall be unsecured and interest free and made without regard to Indemnitee’s ability to repay such advances. Indemnitee hereby


  
 -5- 












 
undertakes to repay any advance to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company. This Section 8 shall not apply to the extent
advancement is prohibited by law and shall not apply to any Proceeding for which indemnity is not permitted under this Agreement, but shall apply to any Proceeding referenced in Section 7(b) or 7(c) prior to a determination that Indemnitee is
not entitled to be indemnified by the Company. 
 9.    Procedures for Notification and Defense of Claim. 

(a)    Indemnitee shall notify the Company in writing of any matter with respect to which Indemnitee intends to seek
indemnification or advancement of Expenses as soon as reasonably practicable following the receipt by Indemnitee of notice thereof. The written notification to the Company shall include, in reasonable detail, a description of the nature of the
Proceeding and the facts underlying the Proceeding. The failure by Indemnitee to notify the Company will not relieve the Company from any liability which it may have to Indemnitee hereunder or otherwise than under this Agreement, and any delay in so
notifying the Company shall not constitute a waiver by Indemnitee of any rights. 
 (b)    If, at the time of the
receipt of a notice of a Proceeding pursuant to the terms hereof, the Company has directors’ and officers’ liability insurance in effect, the Company shall give prompt notice of the commencement of the Proceeding to the insurers in
accordance with the procedures set forth in the applicable policies. The Company shall thereafter take all commercially-reasonable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in
accordance with the terms of such policies. 
 (c)    In the event the Company may be obligated to make any indemnity in
connection with a Proceeding, the Company shall be entitled to assume the defense of such Proceeding with counsel approved by Indemnitee, which approval shall not be unreasonably withheld, upon the delivery to Indemnitee of written notice of its
election to do so. After delivery of such notice, approval of such counsel by Indemnitee and the retention of such counsel by the Company, the Company will not be liable to Indemnitee for any fees or expenses of counsel subsequently incurred by
Indemnitee with respect to the same Proceeding. Notwithstanding the Company’s assumption of the defense of any such Proceeding, the Company shall be obligated to pay the fees and expenses of Indemnitee’s counsel to the extent (i) the
employment of counsel by Indemnitee is authorized by the Company, (ii) counsel for the Company or Indemnitee shall have reasonably concluded that there is a conflict of interest between the Company and Indemnitee in the conduct of any such
defense such that Indemnitee needs to be separately represented, (iii) the fees and expenses are non-duplicative and reasonably incurred in connection with Indemnitee’s role in the Proceeding despite
the Company’s assumption of the defense, (iv) the Company is not financially or legally able to perform its indemnification obligations or (v) the Company shall not have retained, or shall not continue to retain, such counsel to
defend such Proceeding. The Company shall have the right to conduct such defense as it sees fit in its sole discretion. Regardless of any provision in this Agreement, Indemnitee shall have the right to employ counsel in any


  
 -6- 












 
Proceeding at Indemnitee’s personal expense. The Company shall not be entitled, without the consent of Indemnitee, to assume the defense of any claim brought by or in the right of the
Company. 
 (d)    Indemnitee shall give the Company such information and cooperation in connection with the Proceeding
as may be reasonably appropriate. 
 (e)    The Company shall not be liable to indemnify Indemnitee for any settlement
of any Proceeding (or any part thereof) without the Company’s prior written consent, which shall not be unreasonably withheld. 

(f)    The Company shall not settle any Proceeding (or any part thereof) without Indemnitee’s prior written consent,
which shall not be unreasonably withheld. 
 10.    Procedures upon Application for Indemnification.  

(a)    To obtain indemnification, Indemnitee shall submit to the Company a written request, including therein or therewith
such documentation and information as is reasonably available to Indemnitee and as is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification following the final disposition of the Proceeding. The
Company shall, as soon as reasonably practicable after receipt of such a request for indemnification, advise the board of directors that Indemnitee has requested indemnification. Any delay in providing the request will not relieve the Company from
its obligations under this Agreement, except to the extent such failure is prejudicial. 
 (b)    Upon written request
by Indemnitee for indemnification pursuant to Section 10(a), a determination, if required by applicable law, with respect to Indemnitee’s entitlement thereto shall be made in the specific case (i) if a Change in Control shall have
occurred, by Independent Counsel in a written opinion to the Company’s board of directors, a copy of which shall be delivered to Indemnitee or (ii) if a Change in Control shall not have occurred, (A) by a majority vote of the
Disinterested Directors, even though less than a quorum of the Company’s board of directors, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum of the
Company’s board of directors, (C) if there are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Company’s board of directors, a copy of which shall be
delivered to Indemnitee or (D) if so directed by the Company’s board of directors, by the stockholders of the Company. If it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten
days after such determination. Indemnitee shall 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 that is not privileged or otherwise protected from disclosure and that is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or expenses (including
attorneys’ fees and disbursements) reasonably incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company, to the extent permitted by applicable law. 

  
 -7- 












 (c)    In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section 10(b), the Independent Counsel shall be selected as provided in this Section 10(c). If a Change in Control shall not have occurred, the Independent Counsel shall be selected by the
Company’s board of directors, and the Company shall give written notice to Indemnitee advising him or her of the identity of the Independent Counsel so selected. If a Change in Control shall have occurred, the Independent Counsel shall be
selected by Indemnitee (unless Indemnitee shall request that such selection be made by the Company’s board of directors, in which event the preceding sentence shall apply), and Indemnitee shall give written notice to the Company advising it of
the identity of the Independent Counsel so selected. In either event, Indemnitee or the Company, as the case may be, may, within ten days after such written notice of selection shall have been given, deliver to the Company or to Indemnitee, as the
case may be, 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 1 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall 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 a court has determined that such objection is without merit. If, within 20 days after
the later of (i) submission by Indemnitee of a written request for indemnification pursuant to Section 10(a) hereof and (ii) the final disposition of the Proceeding, the parties have not agreed upon an Independent Counsel, either the
Company or Indemnitee may petition a court of competent jurisdiction for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and for the appointment as Independent
Counsel of a person selected by the court or by such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 10(b)
hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 12(a) of this Agreement, the Independent Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the
applicable standards of professional conduct then prevailing). 
 (d)    The Company agrees to pay the reasonable fees
and expenses of any Independent Counsel and to fully indemnify such counsel against any and all Expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. 

11.    Presumptions and Effect of Certain Proceedings. 

(a)    In making a determination with respect to entitlement to indemnification hereunder, the person, persons or entity
making such determination shall, to the fullest extent not prohibited by law, presume that Indemnitee is entitled to 

  
 -8- 












 
indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 10(a) of this Agreement, and the Company shall, to the fullest
extent not prohibited by law, have the burden of proof to overcome that presumption in connection with the making by such person, persons or entity of any determination contrary to that presumption. 

(b)    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, shall 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 they 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 their
conduct was unlawful. 
 (c)    For purposes of any determination of good faith, Indemnitee shall be deemed to have
acted in good faith to the extent Indemnitee relied in good faith on (i) the records or books of account of the Enterprise, including financial statements, (ii) information supplied to Indemnitee by the officers of the Enterprise in the
course of their duties, (iii) the advice of legal counsel for the Enterprise or its board of directors or counsel selected by any committee of the board of directors or (iv) information or records given or reports made to the Enterprise by
an independent certified public accountant, an appraiser, investment banker or other expert selected with reasonable care by the Enterprise or its board of directors or any committee of the board of directors. The provisions of this
Section 11(c) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement. 

(d)    Neither the knowledge, actions nor failure to act of any other director, officer, agent or employee of the
Enterprise shall be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 

12.    Remedies of Indemnitee. 

(a)    Subject to Section 12(e), in the event that (i) a determination is made pursuant to Section 10 of
this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 8 or 12(d) of this Agreement, (iii) no determination of entitlement to
indemnification shall have been made pursuant to Section 10 of this Agreement within 90 days after the later of the receipt by the Company of the request for indemnification or the final disposition of the Proceeding, (iv) payment of
indemnification pursuant to this Agreement is not made (A) within ten days after a determination has been made that Indemnitee is entitled to indemnification or (B) with respect to indemnification pursuant to Sections 4, 5 and 12(d)
of this Agreement, within 30 days after receipt by the Company of a written request therefor, or (v) the Company or any other person or entity 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 

  
 -9- 












 
deny, or to recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee hereunder, Indemnitee shall be entitled to an adjudication by a court of competent jurisdiction
of their entitlement to such indemnification or advancement of Expenses. Alternatively, Indemnitee, at their option, may seek an award in arbitration with respect to their entitlement to such indemnification or advancement of Expenses, to be
conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall 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 12(a); provided, however, that the foregoing clause shall not apply in respect of a proceeding brought by Indemnitee to enforce their rights under
Section 4 of this Agreement. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration in accordance with this Agreement. 

(b)    Neither (i) the failure of the Company, its board of directors, any committee or subgroup of the board of
directors, Independent Counsel or stockholders to have made a determination that indemnification of Indemnitee is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor (ii) an actual determination by the
Company, its board of directors, any committee or subgroup of the board of directors, Independent Counsel or stockholders that Indemnitee has not met the applicable standard of conduct, shall create a presumption that Indemnitee has or has not met
the applicable standard of conduct. In the event that a determination shall have been made pursuant to Section 10 of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to
this Section 12 shall be conducted in all respects as a de novo trial, or arbitration, on the merits, and Indemnitee shall not be prejudiced by reason of that adverse determination. In any judicial proceeding or arbitration commenced
pursuant to this Section 12, the Company shall, to the fullest extent not prohibited by law, have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be. 

(c)    To the fullest extent not prohibited by law, the Company shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section 12 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company
is bound by all the provisions of this Agreement. If a determination shall have been made pursuant to Section 10 of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial
proceeding or arbitration commenced pursuant to this Section 12, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statements not materially misleading, in
connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d)    To the extent not prohibited by law, the Company shall indemnify Indemnitee against all Expenses that are incurred
by Indemnitee in connection with any action for indemnification or advancement of Expenses from the Company under this 

  
 -10- 












 
Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company to the extent Indemnitee is successful in such action, and, if requested by
Indemnitee, shall (as soon as reasonably practicable, but in any event no later than 60 days, after receipt by the Company of a written request therefor) advance such Expenses to Indemnitee, subject to the provisions of Section 8. 

(e)    Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification
shall be required to be made prior to the final disposition of the Proceeding. 
 13.    Contribution. To the
fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amounts incurred by Indemnitee, whether for
Expenses, judgments, fines or amounts paid or to be paid in settlement, 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 events and transactions giving rise to such Proceeding; and (ii) the relative fault of Indemnitee and the Company (and
its other directors, officers, employees and agents) in connection with such events and transactions. 
 14.    Non-exclusivity. The rights of indemnification and to receive advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be
entitled under applicable law, the Company’s certificate of incorporation or bylaws, any agreement, a vote of stockholders or a resolution of directors, or otherwise. 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 Company’s certificate of incorporation and bylaws and this Agreement, it is the intent of the parties hereto that Indemnitee shall
enjoy by this Agreement the greater benefits so afforded by such change, subject to the restrictions expressly set forth herein or therein. Except as expressly set forth herein, no right or remedy herein conferred is intended to be exclusive of any
other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. Except as expressly set forth herein, the
assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 

15.    Primary Responsibility. The Company acknowledges that Indemnitee has or may have certain rights to
indemnification, advancement of expenses, and/or insurance provided by outside sources other than the Company and its insurance providers (the “Secondary Indemnitor”). The Company agrees that, as between the Company and the
Secondary Indemnitor, the Company is primarily responsible for amounts required to be indemnified or advanced under the Company’s certificate of incorporation or bylaws or this Agreement and any obligation of the Secondary Indemnitor to provide
indemnification or advancement for the same amounts is 

  
 -11- 












 
secondary to those Company obligations. The Company waives, relinquishes and releases any right of contribution, subrogation or other recovery against the Secondary Indemnitor with respect to the
liabilities for which the Company is primarily responsible under this Section 15. In the event of any payment by the Secondary Indemnitor of amounts otherwise required to be indemnified or advanced by the Company under the Company’s
certificate of incorporation or bylaws or this Agreement, the Secondary Indemnitor shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee for indemnification or advancement of expenses under the
Company’s certificate of incorporation or bylaws or this Agreement. The Secondary Indemnitor is an express third-party beneficiary of the terms of this Section 15. 

16.    No Duplication of Payments. Subject to Section 15 above, the Company shall not be liable under this
Agreement to make any payment of amounts otherwise indemnifiable hereunder (or for which advancement is provided hereunder) if and to the extent that Indemnitee has otherwise actually received payment for such amounts under any insurance policy,
contract, agreement or otherwise. 
 17.    Insurance. To the extent that the Company maintains an insurance
policy or policies providing liability insurance for directors, trustees, general partners, managing members, officers, employees, agents or fiduciaries of the Company or any other Enterprise, Indemnitee shall be covered by such policy or policies
to the same extent as the most favorably-insured persons under such policy or policies in a comparable position. 

18.    Subrogation. Subject to Section 15, in the event of any payment under this Agreement, the Company shall
be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall 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. 
 19.    Services to the Company. Indemnitee agrees to serve
as a director or officer of the Company or, at the request of the Company, as a director, trustee, general partner, managing member, officer, employee, agent or fiduciary of another Enterprise, for so long as Indemnitee is duly elected or appointed
or until Indemnitee tenders their resignation or is removed from such position. 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), in
which event the Company shall have no obligation under this Agreement to continue Indemnitee in such position. This Agreement shall not be deemed an employment contract between the Company (or any of its subsidiaries or any Enterprise) and
Indemnitee. Indemnitee specifically acknowledges that any employment with the Company (or any of its subsidiaries or any Enterprise) is at will, and Indemnitee may be discharged at any time for any reason, with or without cause, with or without
notice, except as may be otherwise expressly provided in any executed, written employment contract between Indemnitee and the Company (or any of its subsidiaries or any Enterprise), any existing formal severance policies adopted by the
Company’s board of directors or, with respect to service as a director or officer of the Company, the Company’s certificate of incorporation or bylaws or the DGCL. No such document shall be subject to any oral modification thereof.

 20.    Duration. This Agreement shall continue until and
terminate upon the later of (a) ten years after the date that Indemnitee shall have ceased to serve as a director or officer of the Company or as a director, trustee, general partner, managing member, officer, employee, agent or fiduciary of
any other Enterprise, as applicable; or (b) one year after the final termination of any Proceeding, including any appeal, then 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 12 of this Agreement relating thereto. 

21.    Successors. This Agreement shall be binding upon the Company and its 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, and shall inure to the benefit of Indemnitee and Indemnitee’s heirs, executors and
administrators. The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company, by written agreement, expressly to
assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. 

22.    Severability. Nothing in this Agreement is intended to require or shall be construed as requiring the
Company to do or fail to do any act in violation of applicable law. The Company’s inability, pursuant to court order or other applicable law, to perform its obligations under this Agreement shall not constitute a breach of this Agreement. If
any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (i) 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) shall not in any way be affected or impaired thereby and
shall remain enforceable to the fullest extent permitted by law; (ii) such provision or provisions shall 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 (iii) 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) shall be construed so as to give effect to the intent manifested thereby. 

23.    Enforcement. 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 as a director or officer of the Company.

however, that this Agreement is a supplement to and in furtherance of the Company’s certificate of incorporation and bylaws and applicable law. 

25.    Modification and Waiver. No supplement, modification or amendment to this Agreement shall be binding unless
executed in writing by the parties hereto. No amendment, alteration or repeal of this Agreement shall adversely affect any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in their Corporate
Status prior to such amendment, alteration or repeal. No waiver of any of the provisions of this Agreement shall constitute or be deemed a waiver of any other provision of this Agreement nor shall any waiver constitute a continuing waiver.

be mailed by registered or certified mail, postage prepaid, sent by facsimile or electronic mail or otherwise delivered by hand, messenger or courier service addressed:

to the relevant electronic mail address, if sent during normal business hours of the recipient, or if not sent during normal business hours of the recipient, then on the recipient’s next business day.

validity as if served upon such party personally within the State of Delaware, (iv) waive any objection to the laying of venue of any such action or proceeding in the Delaware Court of Chancery, and (v) waive, and agree not to plead or to
make, any claim that any such action or proceeding brought in the Delaware Court of Chancery has been brought in an improper or inconvenient forum. 

28.    Counterparts. This Agreement may be executed in one or more counterparts, each of which shall for all
purposes be deemed to be an original but all of which together shall constitute one and the same Agreement. This Agreement may also be executed and delivered by facsimile signature and in counterparts, each of which shall for all purposes be deemed
to be an original but all of which together shall constitute 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.
