Exhibit 10.3


 


INDEMNITY AGREEMENT


 


THIS INDEMNITY
AGREEMENT (this “Agreement”) is made as of November 1, 2022, by and between M3-Brigade Acquisition III Corp.,
a Delaware corporation (the “Company”), and William L. Transier (“Indemnitee”).


 


RECITALS


 


WHEREAS,
highly competent persons have become more reluctant to serve publicly-held corporations as directors, officers or in other capacities
unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and
actions against them arising out of their service to and activities on behalf of such 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;


 


WHEREAS,
directors, officers and other persons in service to corporations or business enterprises are being increasingly subjected to expensive
and time-consuming litigation relating to, among other things, matters that traditionally would have been brought only against the Company
or business enterprise itself;


 


WHEREAS,
the Amended and Restated Certificate of Incorporation (the “Charter”) and the Bylaws (the “Bylaws”)
of the Company require indemnification of the officers and directors of the Company. Indemnitee may also be entitled to indemnification
pursuant to applicable provisions of the Delaware General Corporation Law (“DGCL”). The Charter, Bylaws and
the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts
may be entered into between the Company and members of the Board, 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 stockholders and that the Company should act to assure such persons that there will be increased certainty of such
protection in the future;


 


WHEREAS,
it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, hold harmless, exonerate and to
advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve
the Company free from undue concern that they will not be so protected against liabilities;


 


WHEREAS,
this Agreement is a supplement to and in furtherance of the Charter and Bylaws 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, advisor or in another capacity 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 Indemnitee be so indemnified.

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, in each case as
provided in Section 17. This Agreement, however, shall not impose any obligation on Indemnitee or the Company to continue Indemnitee’s

with such Proceeding or any claim, issue or matter therein.


 


4.  [INTENTIONALLY
OMITTED.]


 


5.  INDEMNIFICATION
FOR EXPENSES OF A PARTY WHO IS WHOLLY OR PARTLY SUCCESSFUL. Notwithstanding any other provisions of this Agreement except for 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, indemnify, hold harmless and exonerate Indemnitee against all Expenses
actually and reasonably incurred by Indemnitee in connection therewith. If Indemnitee is not wholly successful in such Proceeding but
is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company
shall, to the fullest extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee against all Expenses actually
and reasonably incurred by Indemnitee or on Indemnitee’s 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,
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 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 except for Section 27, to the extent that Indemnitee
is, by reason of Indemnitee’s Corporate Status, a witness or deponent in any Proceeding to which Indemnitee was or is not a party
or threatened to be made a party, Indemnitee shall, to the fullest extent permitted by applicable law, be indemnified, held harmless and
exonerated against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith.


 






    	 	5	 



     


    

 


7.  ADDITIONAL
INDEMNIFICATION, HOLD HARMLESS AND EXONERATION RIGHTS. Notwithstanding any limitation in Sections 3, or 5 and except for Section 27,
the Company shall, to the fullest extent permitted by applicable law, 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, 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, liabilities, fines,
penalties and amounts paid in settlement) actually and reasonably incurred by Indemnitee in connection with the Proceeding.


 


8.  CONTRIBUTION
IN THE EVENT OF JOINT LIABILITY.


 


(a) To
the fullest extent permissible under applicable law, 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.


 


(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.  JOINTLY
INDEMNIFIABLE CLAIMS.


 


Except as set forth
in Section 27, given that certain Jointly Indemnifiable Claims may arise due to the relationship between the Indemnitee-Related Entities
and the Company and the service of the Indemnitee as a director and/or officer of the Company, the Company acknowledges and agrees that
the Company shall be fully and primarily responsible for the payment to the Indemnitee in respect of indemnification and advancement of
expenses in connection with any such Jointly Indemnifiable Claim, pursuant to and in accordance with the terms of this Agreement, irrespective
of any right of recovery the Indemnitee may have from the Indemnitee-Related Entities. Notwithstanding anything contained herein to the
contrary, under no circumstance shall the Company be entitled to any right of subrogation or contribution by the Indemnitee-Related Entities
and no right of recovery the Indemnitee may have from the Indemnitee-Related Entities shall reduce or otherwise alter the rights of the
Indemnitee or the obligations of the Company hereunder. In the event that any of the Indemnitee-Related Entities shall make any payment
to the Indemnitee in respect of indemnification or advancement of Expenses with respect to any Jointly Indemnifiable Claim, the Company
agrees that such payment or advancement shall not extinguish or affect in any way the rights of the Indemnitee under this Agreement and
further agrees that the Indemnitee-Related Entity making such payment shall be subrogated to the extent of such payment to all of the
rights of recovery of the Indemnitee against the Company. Each of the Indemnitee-Related Entities shall be third-party beneficiaries with
respect to this Section 9, entitled to enforce this Section 9 against the Company as though each such Indemnitee-Related Entity were a
party to this Agreement.

10.  ADVANCES
OF EXPENSES; DEFENSE OF CLAIM.


 


(a) Notwithstanding
any provision of this Agreement to the contrary, except for Section 27, and to the fullest extent not prohibited by applicable law, 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
law, be unsecured and interest free. Advances shall, to the fullest extent permitted by law, 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, 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, held harmless or exonerated by the Company
under the provisions of this Agreement, the Charter, the Bylaws, applicable law or otherwise.


 


(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, liability, fine,
penalty or limitation on Indemnitee without Indemnitee’s prior written consent.


 


11.  PROCEDURE
FOR NOTIFICATION AND APPLICATION FOR INDEMNIFICATION; EXCLUSION.


 


(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.


 


(c) Notwithstanding
anything in this Agreement to the contrary, except as set forth in Sections 14(f) and (g), prior to a Change of Control, the Company shall
not be obligated under this Agreement to make any indemnification, advance Expenses, hold harmless or exoneration payment 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 prior to its initiation or (ii) the Proceeding is one to enforce Indemnitee’s rights under this Agreement.

12.
 PROCEDURE UPON APPLICATION FOR INDEMNIFICATION.


 


(a) A
determination, if required by applicable law, with respect to Indemnitee’s entitlement to indemnification shall be made in the specific
case by one of the following methods: (i) if no Change in Control has occurred (x) by a majority vote of the Disinterested Directors,
even though less than a quorum of the Board, (y) by a committee of Disinterested Directors, even though less than a quorum of the Board,
or (z) if there are no Disinterested Directors, or if such Disinterested Directors so direct, by Independent Counsel in a written opinion
to the Board, a copy of which shall be delivered to Indemnitee; or (ii) if a Change in Control has occurred, by Independent Counsel in
a written opinion to the Board, a copy of which shall be delivered to Indemnitee. 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 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 Indemnitee 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.
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 law, 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; 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.


 


(c) The
termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement (whether with or without court
approval) or conviction, or upon a plea of nolo contendere or its equivalent, shall not of itself adversely affect the right of Indemnitee
to indemnification or create a presumption that Indemnitee did not meet any particular standard of conduct or have any particular belief
or that a court has determined that indemnification is not permitted by applicable law. In addition, neither the failure of the Independent
Counsel to have made a determination as to whether Indemnitee has met any particular standard of conduct or had any particular belief,
nor an actual determination by the Independent Counsel that Indemnitee has not met such standard of conduct or did not have such belief,
prior to the commencement of legal proceedings by Indemnitee to secure a judicial determination that Indemnitee should be indemnified
under applicable law shall be a defense to Indemnitee’s claim or create a presumption that Indemnitee has not met any particular
standard of conduct or did not have any particular belief.

(d) For
purposes of any determination of good faith, Indemnitee shall be deemed to have 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 if Indemnitee’s actions or omissions to act are taken in good
faith reliance upon the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee
by the directors, trustees, general partners, managers or managing members 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 of the Enterprise, 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 of the Enterprise, 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, 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 Section 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, Indemnitee shall be entitled to an adjudication
by the Delaware Court to such indemnification, hold harmless, exoneration, contribution or advancement rights. Alternatively, Indemnitee,
at Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration
Rules and Mediation Procedures of the American Arbitration Association. Except as set forth herein, the provisions of Delaware law (without
regard to its conflict of laws rules) shall apply to any such arbitration. The Company shall not oppose Indemnitee’s right to seek
any such adjudication or award in arbitration.


 


(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, and exonerated and 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, and 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).


 






    	 	10	 



     


    

 


(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.


 


(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 law 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 Charter, or the Bylaws 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 Delaware 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.


 


15.  SECURITY.
Notwithstanding anything herein to the contrary, except for 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, the Charter, the Bylaws, any agreement, a vote of stockholders 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 Indemnitee’s Corporate
Status prior to such amendment, alteration or repeal. To the extent that a change in applicable law, 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 Charter, the Bylaws or this Agreement, then this Agreement shall automatically be deemed to be amended to require that the Company
indemnify the Indemnitee to the fullest extent permitted by law. 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.


 






    	 	11	 



     


    

 


(b) The
DGCL, the Charter and the Bylaws 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 Indemnitee or incurred by or on behalf of Indemnitee or in such capacity
as a director, officer, employee or agent of the Company, or arising out of Indemnitee’s status as such, whether or not the Company
would have the power to indemnify Indemnitee against such liability under the provisions of this Agreement or under the DGCL, as it may
then be in effect. 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 take all necessary or desirable 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.


 


(d) In
the event of any payment under this Agreement, the Company, to the fullest extent permitted by law, 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. 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 except for 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.


 


(e) Notwithstanding
anything contained herein, the Company is the primary indemnitor.


 


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 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 Indemnitee’s
Corporate Status, whether or not Indemnitee 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 law; (b) 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 (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.


 


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 Charter or Bylaws 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 Indemnitee’s 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.


 


(d) 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 law, 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 Indemnitee may
be entitled. The Company and Indemnitee further agree that Indemnitee shall, to the fullest extent permitted by law, 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. The Company hereby waives any such requirement
of such a bond or undertaking to the fullest extent permitted by law.


 


20.  MODIFICATION
AND WAIVER. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by the Company
and Indemnitee. 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.

22.  APPLICABLE
LAW AND CONSENT TO JURISDICTION. 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 Delaware, without regard to its conflict of laws rules. Except with respect to any
arbitration commenced by Indemnitee pursuant to Section 14(a) of this Agreement, to the fullest extent permitted by law, 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

permitted by law, the parties hereby agree that the mailing of process and other papers in connection with any such action or proceeding
in the manner provided by Section 21 or in such other manner as may be permitted by law, 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

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.


 






    	 	14	 



     


    

 


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 law, 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 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.
