 Exhibit 10.5 

INDEMNITY AGREEMENT 
 THIS
INDEMNITY AGREEMENT (this “Agreement”) is made as of [ ● ], 2021, by and between Supernova Partners Acquisition Company III, Ltd., a Cayman Islands exempted company (the “Company”),
and (“Indemnitee”). 
 WHEREAS, highly competent persons have become more reluctant to serve publicly-held companies and
corporations as directors, officers or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to
and activities on behalf of such companies and corporations; 
 WHEREAS, the Board of Directors of the Company (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. The amended and restated memorandum and articles of association of the Company (the “Articles”) provide for the indemnification of the officers and directors of the Company. Indemnitee may also be entitled to
indemnification pursuant to applicable Cayman Islands law. The Articles 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, officers and other persons with respect to indemnification, hold harmless, exoneration, advancement and reimbursement rights; 
 WHEREAS,
the uncertainties relating to such insurance and to indemnification have increased 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’s shareholders 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, hold harmless, exonerate and to advance
expenses on behalf of, such persons to the fullest extent permitted by applicable law and the Articles so that they will serve or continue to serve the Company free from undue concern that they will not be so protected against liabilities; 

WHEREAS, this Agreement is a supplement to and in furtherance of the Articles of the Company and any resolutions adopted pursuant thereto, and shall
not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; and 
 WHEREAS, Indemnitee may not be willing
to serve as an officer or director without adequate protection, and the Company desires Indemnitee 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 he or she be so indemnified. 
 NOW, THEREFORE, in consideration of the premises and the covenants contained herein and subject to the
provisions of the letter agreement dated as of [ ● ], 2021, the Company and Indemnitee do hereby covenant and agree as follows: 
  

	1.	 SERVICES TO THE COMPANY 



In consideration of the Company’s covenants and obligations hereunder, Indemnitee will serve or continue to serve as an officer, director, advisor, key
employee or in any other capacity of the Company, as applicable, for so long as Indemnitee is duly elected or appointed or retained or until Indemnitee 

  
 1 













 
tenders his or her resignation or until Indemnitee is removed. The foregoing notwithstanding, this Agreement shall continue in full force and effect after Indemnitee has ceased to serve as a
director, officer, advisor, key employee or in any other capacity of the Company, as provided in Section 17. This Agreement, however, shall not impose any obligation on Indemnitee or the Company to continue Indemnitee’s service to the
Company beyond any period otherwise required by applicable law and the Articles or by other agreements or commitments of the parties, if any.

reason of the fact that Indemnitee is or was a director or officer of the Company, by reason of any action (or failure to act) taken by him or her or of any action (or failure to act) on his or her part while acting as a director or officer of the
Company, or by reason of the fact that he or she is or was serving at the request of the Company as a director, officer, trustee, general partner, managing member, fiduciary, employee or agent of 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, reimbursement, or advancement of expenses can be provided under this Agreement.

	3.	 INDEMNITY IN THIRD-PARTY PROCEEDINGS 



To the fullest extent permitted by applicable law and the Articles, the Company shall indemnify, hold harmless and exonerate Indemnitee in accordance with the
provisions of this Section 3 if Indemnitee was, is, or is threatened to be made, a party to or a participant (as a witness, deponent or otherwise) in any Proceeding, other than a Proceeding by or in the right of the Company to procure a
judgment in its favor by reason of Indemnitee’s Corporate Status. Pursuant to this Section 3, Indemnitee shall be indemnified, held harmless and exonerated against all Expenses, judgments, liabilities, fines, penalties 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, penalties and amounts paid in settlement) actually, and reasonably incurred by Indemnitee or on
his or her behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he or she 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 his or her conduct was unlawful; provided, in no event shall Indemnitee be entitled to be indemnified, held harmless or advanced any amounts hereunder in respect of any Expenses,
judgments, liabilities, fines, penalties and amounts paid in settlement (if any) that Indemnitee may incur by reason of his or her own actual fraud or intentional misconduct. Indemnitee shall not be found to have committed actual fraud or
intentional misconduct for any purpose of this Agreement unless or until a court of competent jurisdiction shall have made a finding to that effect. 
  

	4.	 INDEMNITY IN PROCEEDINGS BY OR IN THE RIGHT OF THE COMPANY 



To the fullest extent permitted by applicable law and the Articles, the Company shall indemnify, hold harmless and exonerate Indemnitee in accordance with the
provisions of this Section 4 if Indemnitee was, is, or is threatened to be made, a party to or a participant (as a witness, deponent or otherwise) in any Proceeding by or in the right of the Company to procure a judgment in its favor by reason
of Indemnitee’s Corporate Status. Pursuant to this Section 4, Indemnitee shall be indemnified, held harmless and exonerated against all Expenses actually and reasonably incurred by him or her or on his or her behalf in connection with such
Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company. No indemnification, hold harmless or exoneration for
Expenses shall be made under this Section 4 in respect of any claim, issue or matter as to which Indemnitee shall have been finally adjudged by a court of competent jurisdiction to be liable to the Company, unless and only to the extent that
any court in which the Proceeding was brought or the Delaware Court 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, to be held harmless or to exoneration. 
  

	5.	 INDEMNIFICATION FOR EXPENSES OF A PARTY WHO IS WHOLLY OR PARTLY SUCCESSFUL 



Notwithstanding any other provisions of this Agreement, but subject to Section 27, to the extent that Indemnitee was or is, by reason of Indemnitee’s
Corporate Status, a party to (or a participant in) and is successful, on the merits or otherwise, in any Proceeding or in defense of any claim, issue or matter therein, in whole or in part, the Company shall, to the fullest extent permitted by
applicable law and the Articles, indemnify, hold harmless and exonerate Indemnitee against all Expenses actually and reasonably incurred by him or her in connection therewith. If Indemnitee is not wholly successful in such Proceeding


  
 5 













 
but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall, to the fullest extent permitted by applicable
law and the Articles, indemnify, hold harmless and exonerate Indemnitee against all Expenses actually and reasonably incurred by him or her or on his or her behalf in connection with each successfully resolved claim, issue or matter. If Indemnitee
is not wholly successful in such Proceeding, the Company also shall, to the fullest extent permitted by applicable law and the Articles, indemnify, hold harmless and exonerate Indemnitee against all Expenses reasonably incurred in connection with a
claim, issue or matter related to any claim, issue, or matter on which Indemnitee was successful. 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, shall be deemed to be a successful result as to such claim, issue or matter. 
  

	6.	 INDEMNIFICATION FOR EXPENSES OF A WITNESS 



Notwithstanding any other provision of this Agreement, but subject to Section 27, to the extent that Indemnitee is, by reason of his or her Corporate
Status, a witness or deponent in any Proceeding to which Indemnitee is not a party or threatened to be made a party, he or she shall, to the fullest extent permitted by applicable law and the Articles, be indemnified, held harmless and exonerated
against all Expenses actually and reasonably incurred by him or her or on his or her behalf in connection therewith. 
  

	7.	 ADDITIONAL INDEMNIFICATION, HOLD HARMLESS AND EXONERATION RIGHTS 



Notwithstanding any limitation in Sections 3, 4 or 5, but subject to Section 27, the Company shall, to the fullest extent permitted by applicable law and
the Articles, indemnify, hold harmless and exonerate Indemnitee 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) against all
Expenses, judgments, fines, penalties 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, penalties and amounts paid in
settlement) actually and reasonably incurred by Indemnitee in connection with the Proceeding. No indemnification, hold harmless or exoneration rights shall be available under this Section 7 on account of Indemnitee’s conduct which
constitutes a breach of Indemnitee’s duty of loyalty to the Company or its shareholders or is an act or omission not in good faith or which involves intentional misconduct or a knowing violation of the law. 

 

	8.	 CONTRIBUTION IN THE EVENT OF JOINT LIABILITY 



(a) To the fullest extent permissible under applicable law and the Articles, if the indemnification, hold harmless and/or exoneration rights provided for in
this Agreement are unavailable to Indemnitee in whole or in part for any reason whatsoever, the Company, in lieu of indemnifying, holding harmless or exonerating Indemnitee, shall pay, in the first instance, the entire amount incurred by Indemnitee,
whether for judgments, liabilities, fines, penalties, amounts paid or to be paid in settlement and/or for Expenses, in connection with any Proceeding without requiring Indemnitee to contribute to such payment, and the Company hereby waives and
relinquishes any right of contribution it may have at any time against Indemnitee. 
 (b) The Company shall not enter into any settlement of any Proceeding
in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee. 

  
 6 













 (c) The Company hereby agrees to fully indemnify, hold harmless and exonerate Indemnitee from any claims for
contribution which may be brought by officers, directors or employees of the Company other than Indemnitee who may be jointly liable with Indemnitee. Indemnitee shall seek payments or advances from the Company only to the extent that such payments
or advances are unavailable from any insurance policy of the Company covering Indemnitee. 
  

	9.	 EXCLUSIONS 



Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnification, advance Expenses, hold
harmless or exoneration payment in connection with any claim made against Indemnitee: 
 (a) for which payment has actually been received by or on behalf of
Indemnitee under any insurance policy or other indemnity or advancement provision, except with respect to any excess beyond the amount actually received under any insurance policy, contract, agreement, other indemnity or advancement provision or
otherwise; 
 (b) for 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 any successor rule) or similar provisions of state statutory law or common law; or 
 (c) except as
otherwise provided in Sections 14(f) and (g) hereof, prior to a Change in Control, in connection with any Proceeding (or any part of any Proceeding) 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 Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the
indemnification, hold harmless or exoneration payment, in its sole discretion, pursuant to the powers vested in the Company under applicable law and the Articles. 
  

	10.	 ADVANCES OF EXPENSES; DEFENSE OF CLAIM 



(a) Notwithstanding any provision of this Agreement to the contrary, but subject to Section 27, and to the fullest extent not prohibited by applicable law
and the Articles, the Company shall pay the Expenses incurred by Indemnitee (or reasonably expected by Indemnitee to be incurred by Indemnitee within three months) in connection with any Proceeding within ten (10) days after the receipt by the
Company of a statement or statements requesting such advances from time to time, prior to the final disposition of any Proceeding. Advances shall, to the fullest extent permitted by applicable law and the Articles, be unsecured and interest free.
Advances shall, to the fullest extent permitted by applicable law and the Articles, be made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to be indemnified, held
harmless or exonerated under the other provisions of this Agreement. Advances shall include any and all reasonable Expenses incurred pursuing a Proceeding to enforce this right of advancement, including Expenses incurred preparing and forwarding
statements to the Company to support the advances claimed. To the fullest extent required by applicable law and the Articles, such payments of Expenses in advance of the final disposition of the Proceeding shall be made only upon the Company’s
receipt of an undertaking, by or on behalf of Indemnitee, to repay the advanced amounts to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company under the provisions of this Agreement,
applicable law and the Articles or otherwise. If it shall be determined by a final judgment or other final adjudication that Indemnitee was not so entitled to indemnification, any advancement shall be returned to the Company (without interest) by
the Indemnitee. This Section 10(a) shall not apply to any claim made by Indemnitee for which an indemnification, hold harmless or exoneration payment is excluded pursuant to Section 9, but shall apply to any Proceeding referenced in
Section 9(b) prior to a final determination that Indemnitee is liable therefor. 

  
 7 













 (b) The Company will be entitled to participate in the Proceeding at its own expense. 

(c) The Company shall not settle any action, claim or Proceeding (in whole or in part) which would impose any Expense, judgment, fine, penalty or limitation
on Indemnitee without Indemnitee’s prior written consent. 
  

	11.	 PROCEDURE FOR NOTIFICATION AND APPLICATION FOR INDEMNIFICATION 



(a) Indemnitee agrees to notify promptly the Company in writing upon being served with any summons, citation, subpoena, complaint, indictment, information or
other document relating to any Proceeding, claim, issue or matter therein which may be subject to indemnification, hold harmless or exoneration rights, or advancement of Expenses covered hereunder. The failure of Indemnitee to so notify the Company
shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement, or otherwise. 
 (b) Indemnitee may deliver to the
Company a written application to indemnify, hold harmless or exonerate Indemnitee in accordance with this Agreement. Such application(s) may be delivered from time to time and at such time(s) as Indemnitee deems appropriate in his or her sole
discretion. Following such a written application for indemnification by Indemnitee, Indemnitee’s entitlement to indemnification shall be determined according to Section 12(a) of this Agreement. 

 

	12.	 PROCEDURE UPON APPLICATION FOR INDEMNIFICATION 



(a) A determination, if required by applicable law and the Articles, with respect to Indemnitee’s entitlement to indemnification shall be made in the
specific case by one of the following methods, which shall be at the election of Indemnitee: (i) by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (ii) by a committee of such directors
designated by majority vote of such directors, (iii) if there are no Disinterested Directors or if such directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee, or
(iv) by vote of the shareholders by ordinary resolution. The Company promptly will advise Indemnitee in writing with respect to any determination that Indemnitee is or is not entitled to indemnification, including a description of any reason or
basis for which indemnification has been denied. If it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days after such determination. Indemnitee shall reasonably cooperate
with the person, persons or entity making such 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. Any costs or Expenses (including reasonable attorneys’ fees and disbursements)
incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby
agrees to indemnify and to hold Indemnitee harmless therefrom. 
 (b) In the event the determination of entitlement to indemnification is to be made by
Independent Counsel pursuant to Section 12(a) hereof, the Independent Counsel shall be selected as provided in this Section 12(b). The Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection
be made by the Board), and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected and certifying that the Independent Counsel so selected meets the requirements of “Independent
Counsel” as defined in Section 2 of this Agreement. If the Independent Counsel is selected by the Board, the Company shall give written notice to Indemnitee advising him or her of the identity of the Independent Counsel so selected and
certifying that 

  
 8 













 
the Independent Counsel so selected meets the requirements of “Independent Counsel” as defined in Section 2 of this Agreement. In either event, Indemnitee or the Company, as the
case may be, may, within ten (10) days after such written notice of selection shall have been received, 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 2 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 of competent jurisdiction has determined that such objection is without merit. If, within twenty (20) days after submission by Indemnitee of a written request for indemnification
pursuant to Section 11(b) hereof, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition the Delaware Court for resolution of any objection which shall have been made by the Company or
Indemnitee to the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the Delaware Court, and the person with respect to whom all objections are so resolved or the person so
appointed shall act as Independent Counsel under Section 12(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 14(a) of this Agreement, Independent Counsel shall be discharged and relieved of
any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 
 (c) The Company agrees to pay
the reasonable fees and expenses of Independent Counsel and to fully indemnify and hold harmless such Independent Counsel against any and all Expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement
pursuant hereto. 
  

	13.	 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 presume
that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 11(b) of this Agreement, and the Company shall have the burden of proof to overcome that
presumption in connection with the making by any person, persons or entity of any determination contrary to that presumption. Neither the failure of the Company (including by the Disinterested 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 the Disinterested Directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(b) If the person, persons or entity empowered or selected under Section 12 of this Agreement to determine whether Indemnitee is entitled to
indemnification shall not have made a determination within thirty (30) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall, to the fullest extent permitted by applicable
law and the Articles, be deemed to have been made and Indemnitee shall 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 final judicial determination that any or all such indemnification is expressly prohibited under applicable law and the Articles; provided,
however, that such 30-day period may be extended for a reasonable time, not to exceed an additional fifteen (15) 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. 

  
 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, 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 he or she 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
his or her conduct was unlawful. 
 (d) For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if
Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the directors, manager, or officers of the Enterprise in the course of their duties,
or on the advice of legal counsel for the Enterprise, its Board, any committee of the Board or any director, trustee, general partner, manager or managing member, or on information or records given or reports made to the Enterprise, its Board, any
committee of the Board or any director, trustee, general partner, manager or managing member, by an independent certified public accountant or by an appraiser or other expert selected by the Enterprise, its Board, any committee of the Board or any
director, trustee, general partner, manager or managing member. The provisions of this Section 13(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed or found 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 other director, officer, trustee,
partner, manager, managing member, fiduciary, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 

 

	14.	 REMEDIES OF INDEMNITEE 



(a) 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) advancement of Expenses, to the fullest extent permitted by applicable law and the Articles, is not timely made pursuant to Section 10 of this Agreement, (iii) no determination of entitlement to indemnification
shall have been made pursuant to Section 12(a) of this Agreement within thirty (30) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Sections 5, 6, 7 or the
last sentence of Section 12(a) of this Agreement within ten (10) days after receipt by the Company of a written request therefor, (v) a contribution payment is not made in a timely manner pursuant to Section 8 of this Agreement,
(vi) payment of indemnification pursuant to Section 3 or 4 of this Agreement is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification, or (vii) payment to Indemnitee
pursuant to any hold harmless or exoneration rights under this Agreement or otherwise is not made in accordance with this Agreement within ten (10) days after receipt by the Company of a written request therefor, Indemnitee shall be entitled to
an adjudication by the Delaware Court to such indemnification, hold harmless, exoneration, contribution or advancement rights. Alternatively, Indemnitee, at his or her option, may seek an award in arbitration to be conducted by a single arbitrator
pursuant to the Commercial Arbitration Rules and Mediation Procedures of the American Arbitration Association. Except as set forth herein, the Commercial Arbitration Rules and Mediation Procedures of the American Arbitration Association shall apply
to any such arbitration. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 

  
 10 













 (b) In the event that a determination shall have been made pursuant to Section 12(a) of this Agreement
that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 14 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. 
 (c) In any judicial proceeding or arbitration commenced pursuant to this Section 14, Indemnitee
shall be presumed to be entitled to be indemnified, held harmless, exonerated to receive advancement of Expenses under this Agreement and the Company shall have the burden of proving Indemnitee is not entitled to be indemnified, held harmless,
exonerated and to receive advancement of Expenses, as the case may be, and the Company may not refer to or introduce into evidence any determination pursuant to Section 12(a) of this Agreement adverse to Indemnitee for any purpose. If
Indemnitee commences a judicial proceeding or arbitration pursuant to this Section 14, Indemnitee shall not be required to reimburse the Company for any advances pursuant to Section 10 until a final determination is made with respect to
Indemnitee’s entitlement to indemnification (as to which all rights of appeal have been exhausted or lapsed). 
 (d) If a determination shall have been
made pursuant to Section 12(a) 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 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 and the Articles. 
 (e) The Company shall be 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 shall stipulate in any such court or before any such arbitrator that the Company is bound by all the
provisions of this Agreement. 
 (f) The Company shall indemnify and hold harmless Indemnitee to the fullest extent permitted by applicable law and the
Articles against all Expenses and, if requested by Indemnitee, shall (within ten (10) days after the Company’s receipt of such written request) pay to Indemnitee, to the fullest extent permitted by applicable law, such Expenses which are
incurred by Indemnitee in connection with any judicial proceeding or arbitration brought by Indemnitee: (i) to enforce his or her rights under, or to recover damages for breach of, this Agreement or any other indemnification, hold harmless,
exoneration, advancement or contribution agreement or provision of the Articles now or hereafter in effect; or (ii) for recovery or advances under any insurance policy maintained by any person for the benefit of Indemnitee, regardless of the
outcome and whether Indemnitee ultimately is determined to be entitled to such indemnification, hold harmless or exoneration right, advancement, contribution or insurance recovery, as the case may be (unless such judicial proceeding or arbitration
was not brought by Indemnitee in good faith). 
 (g) Interest shall be paid by the Company to Indemnitee at the legal rate under New York law for amounts
which the Company indemnifies, holds harmless or exonerates, or advances, or is obliged to indemnify, hold harmless or exonerate or advance for the period commencing with the date on which Indemnitee requests indemnification, to be held harmless,
exonerated, contribution, reimbursement or advancement of any Expenses and ending with the date on which such payment is made to Indemnitee by the Company. 

  
 11 














	15.	 SECURITY 



Notwithstanding anything herein to the contrary, but subject to Section 27, to the extent requested by Indemnitee and approved by the Board, the Company
may at any time and from time to time provide security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line of credit, funded trust or other collateral. Any such security, once provided to Indemnitee, may not
be revoked or released without the prior written consent of Indemnitee. 
  

	16.	 NON-EXCLUSIVITY; SURVIVAL OF RIGHTS; INSURANCE; SUBROGATION;
PRIORITY OF OBLIGATIONS 


 (a) The rights of Indemnitee 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 and the Articles, the Articles, any agreement, a vote of shareholders or a resolution of directors, or otherwise. No amendment, alteration or repeal of this Agreement or of any
provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any Proceeding (regardless of when such Proceeding is first threatened, commenced or completed) or claim, issue or matter therein arising out of, or
related to, any action taken or omitted by such Indemnitee in his or her Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in applicable law and the Articles, whether by statute or judicial decision, permits
greater indemnification, hold harmless or exoneration rights or advancement of Expenses than would be afforded currently under the Articles or this Agreement, then this Agreement (without any further action by the parties hereto) shall automatically
be deemed to be amended to require that the Company indemnifies the Indemnitee to the fullest extent permitted by applicable law and the Articles. 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. 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. 
 (b) The Articles permit the Company to purchase and
maintain insurance or furnish similar protection or make other arrangements including, but not limited to, providing a trust fund, letter of credit, or surety bond (“Indemnification Arrangements”) on behalf of Indemnitee
against any liability asserted against him or her or incurred by or on behalf of him or in such capacity as a director, officer, employee or agent of the Company, or arising out of his or her status as such, whether or not the Company would have the
power to indemnify him or her against such liability under the provisions of this Agreement and the Articles. The purchase, establishment, and maintenance of any such Indemnification Arrangement shall not in any way limit or affect the rights and
obligations of the Company or of Indemnitee under this Agreement except as expressly provided herein, and the execution and delivery of this Agreement by the Company and Indemnitee shall not in any way limit or affect the rights and obligations of
the Company or the other party or parties thereto under any such Indemnification Arrangement. 
 (c) To the extent that the Company maintains an insurance
policy or policies providing liability insurance for directors, officers, trustees, partners, managers, managing members, fiduciaries, employees, or agents of the Company or of any other Enterprise which such person serves at the request of the
Company, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, trustee, partner, managers, managing member, fiduciary, employee or
agent under such policy or policies. If, at the time the Company receives notice from any source of a Proceeding as to which Indemnitee is a party or a participant (as a witness, deponent or otherwise), the Company has director and officer liability
insurance in effect, the Company shall give prompt notice of such Proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter use commercially reasonable efforts 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. 

  
 12 













 (d) In the event of any payment under this Agreement, the Company, to the fullest extent permitted by
applicable law and the Articles, 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. No such payment by the Company shall be deemed to relieve any insurer of its obligations. 

(e) The Company’s obligation to indemnify, hold harmless, exonerate or advance Expenses hereunder to Indemnitee who is or was serving at the request of
the Company as a director, officer, trustee, partner, manager, managing member, fiduciary, employee or agent of any other Enterprise shall be reduced by any amount Indemnitee has actually received as indemnification, hold harmless or exoneration
payments or advancement of expenses from such Enterprise. Notwithstanding any other provision of this Agreement to the contrary, but subject to Section 27, (i) Indemnitee shall have no obligation to reduce, offset, allocate, pursue or apportion
any indemnification, hold harmless, exoneration, advancement, contribution or insurance coverage among multiple parties possessing such duties to Indemnitee prior to the Company’s satisfaction and performance of all its obligations under this
Agreement, and (ii) the Company shall perform fully its obligations under this Agreement without regard to whether Indemnitee holds, may pursue or has pursued any indemnification, advancement, hold harmless, exoneration, contribution or
insurance coverage rights against any person or entity other than the Company. 
 (f) Notwithstanding anything contained herein, the Company is the primary
indemnitor, and any indemnification or advancement obligation of the Sponsor or its affiliates or members or any other Person is secondary. 
  

	17.	 DURATION OF AGREEMENT 



All agreements and obligations of the Company contained herein shall continue during the period Indemnitee serves as a director or officer of the Company or as
a director, officer, trustee, partner, manager, managing member, fiduciary, employee or agent of any other company or corporation, partnership, joint venture, trust, employee benefit plan or other Enterprise which Indemnitee serves at the request of
the Company and shall continue thereafter so long as Indemnitee shall be subject to any possible Proceeding (including any rights of appeal thereto and any Proceeding commenced by Indemnitee pursuant to Section 14 of this Agreement) by reason
of his or her Corporate Status, whether or not he or she is acting in any such capacity at the time any liability or expense is incurred for which indemnification or advancement can be provided under this Agreement. 

 

	18.	 SEVERABILITY 



If any provision or provisions of this Agreement shall be 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, paragraph or sentence 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 applicable law and the Articles; (b) such provision or
provisions shall be deemed reformed to the extent necessary to conform to applicable law and the Articles 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, paragraph or sentence 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. 

  
 13 














	19.	 ENFORCEMENT AND BINDING EFFECT 



(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, officer or key employee of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director, officer or key employee of the Company. 

(b) Without limiting any of the rights of Indemnitee under the Articles of the Company as they may be amended from time to time, 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. 

(c) The indemnification, hold harmless, exoneration and advancement of expenses rights provided by or granted pursuant to this Agreement shall be 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 and/or assets of the
Company), shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company or a director, officer, trustee, general partner, manager, managing member, fiduciary, employee or agent of any other Enterprise
at the Company’s request, and shall inure to the benefit of Indemnitee and his or her spouse, assigns, heirs, devisees, executors and administrators and other legal representatives. 

(d) The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all, substantially all
or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, 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. 
 (e) The Company and Indemnitee agree herein that a monetary remedy for breach
of this Agreement, at some later date, may be inadequate, impracticable and difficult of proof, and further agree that such breach may cause Indemnitee irreparable harm. Accordingly, the parties hereto agree that Indemnitee may, to the fullest
extent permitted by applicable law and the Articles, enforce this Agreement by seeking, among other things, injunctive relief and/or specific performance hereof, without any necessity of showing actual damage or irreparable harm and that by seeking
injunctive relief and/or specific performance, Indemnitee shall not be precluded from seeking or obtaining any other relief to which he or she may be entitled. The Company and Indemnitee further agree that Indemnitee shall, to the fullest extent
permitted by applicable law and the Articles, be entitled to such specific performance and injunctive relief, including temporary restraining orders, preliminary injunctions and permanent injunctions, without the necessity of posting bonds or other
undertaking in connection therewith. The Company acknowledges that in the absence of a waiver, a bond or undertaking may be required of Indemnitee by a court of competent jurisdiction, and the Company hereby waives any such requirement of such a
bond or undertaking to the fullest extent permitted by applicable law and the Articles. 
  

	20.	 MODIFICATION AND WAIVER 



No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by the parties hereto. No waiver of any of the
provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute a continuing waiver.

This Agreement and the legal relations among the parties shall be governed by, and construed and enforced in accordance with, the laws of the State of New
York, 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, to the fullest extent permitted by applicable law and the Articles, the Company and
Indemnitee hereby irrevocably and unconditionally: (a) agree that any action or proceeding arising out of or in connection with this Agreement shall be brought only in the Delaware Court and not in any other state or federal court in the United
States of America or any court in any other country; (b) 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; (c) waive any
objection to the laying of venue of any such action or proceeding in the Delaware Court; and (d) 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

such action or proceeding in the manner provided by Section 21 or in such other manner as may be permitted by applicable law and the Articles, shall be valid and sufficient service thereof.

	23.	 IDENTICAL 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. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the existence of this Agreement. 

 

	24.	 MISCELLANEOUS 



The headings of the paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect
the construction thereof. 
  

	25.	 PERIOD OF LIMITATIONS 



No legal action shall be brought and no cause of action shall be asserted by or in the right of the Company against Indemnitee, Indemnitee’s spouse,
heirs, executors or personal or legal representatives after the expiration of two years from the date of accrual of such cause of action, and any claim or cause of action of the Company shall be extinguished and deemed released unless asserted by
the timely filing of a legal action within such two-year period; provided, however, that if any shorter period of limitations is otherwise applicable to any such cause of action such shorter period shall
govern. 
  

	26.	 ADDITIONAL ACTS 



If for the validation of any of the provisions in this Agreement any act, resolution, approval or other procedure is required to the fullest extent permitted
by applicable law and the Articles, the Company undertakes to cause such act, resolution, approval or other procedure to be affected or adopted in a manner that will enable the Company to fulfill its obligations under this Agreement. 

 

	27.	 WAIVER OF CLAIMS TO TRUST ACCOUNT 



Notwithstanding anything contained herein to the contrary, Indemnitee hereby agrees that it does not have any right, title, interest or claim of any kind
(each, a “Claim”) in or to any monies in the trust account established in connection with the Company’s initial public offering for the benefit of the Company and holders of shares issued in such offering, and hereby
waives any Claim it may have in the future as a result of, or arising out of, any services provided to the Company and will not seek recourse against such trust account for any reason whatsoever. Accordingly, Indemnitee acknowledges and agrees that
any indemnification provided hereto will only be able to be satisfied by the Company if (i) the Company has sufficient funds outside of the Trust Account to satisfy its obligations hereunder or (ii) the Company consummates a Business
Combination. 
  

	28.	 MAINTENANCE OF INSURANCE 



The Company shall use commercially reasonable efforts to obtain and maintain in effect during the entire period for which the Company is obligated to indemnify
the Indemnitee under this Agreement, one or more policies of insurance with reputable insurance companies to provide the officers/directors of the Company with coverage for losses from wrongful acts and omissions and to ensure the Company’s


  
 16 













 
performance of its indemnification obligations under this Agreement. The Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the
coverage available for any such director or officer under such policy or policies. In all such insurance policies, the Indemnitee shall be named as an insured in such a manner as to provide the Indemnitee with the same rights and benefits as are
accorded to the most favorably insured of the Company’s directors and officers.
