Exhibit 10.4


 


INDEMNIFICATION AGREEMENT


 


THIS INDEMNIFICATION
AGREEMENT (this “Agreement”) is made as of October 1, 2020, by and between HYLIION HOLDINGS CORP.,
a Delaware corporation (the “Company”), and [___] (“Indemnitee”).


 


RECITALS


 


WHEREAS, highly
competent persons have become more reluctant to serve publicly-held corporations as directors or officers 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 as directors and officers, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability
insurance to protect such persons serving the Company and its subsidiaries from certain liabilities. Although the furnishing of
such insurance has been a customary and widespread practice among United States-based corporations and other business enterprises,
the Company believes that, given current market conditions and trends, such insurance may be available to it in the future only
at higher premiums and with more exclusions. At the same time, directors and officers are being increasingly subjected to expensive
and time-consuming litigation. The Second 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 of directors, 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 without adequate protection, and the Company desires Indemnitee to serve
in such capacity. Indemnitee is willing to serve or continue to serve for or on behalf of the Company on the condition that Indemnitee
be so indemnified.


 


NOW, THEREFORE,
in consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree as
follows:


 


TERMS AND CONDITIONS


 


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 or key employee of the Company for so long as Indemnitee is duly elected or appointed or until
Indemnitee tenders Indemnitee’s 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 or officer 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 law or by other agreements or commitments of the parties, if any.

(including, without limitation, a corporation which as a result of such transaction owns the Company or all or substantially all

the election of directors; (2) other than an affiliate of Thomas Healy, no Person (excluding any corporation resulting from such
Business Combination) is the Beneficial Owner, directly or indirectly, of twenty percent (20%) or more of the combined voting power

to the extent that such ownership existed prior to the Business Combination; and (3) at least a majority of the Board of Directors

witness or otherwise by 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 Indemnitee or of any action (or failure to act) on Indemnitee’s part while acting as a director

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, 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 Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee
acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company
and, in the case of a criminal Proceeding, had no reasonable cause to believe that Indemnitee’s conduct was unlawful.


 


4. INDEMNITY
IN PROCEEDINGS BY OR IN THE RIGHT OF THE COMPANY. To the fullest extent permitted by applicable law, 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 Indemnitee
or on Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in
good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. Notwithstanding
the foregoing, 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 provision of this Agreement (other
than the provisions of Section 27 hereof), 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 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 (other than the provisions of Section
27 hereof), 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.


 


7. 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.


 


8. EXCLUSIONS.
Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnification,
advance of 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, contract, agreement or other indemnity or
advancement provision or otherwise, except (i) with respect to any excess beyond the amount actually received under any insurance
policy, contract, agreement, other indemnity or advancement provision or otherwise and (ii) as provided in Section 9 hereof;


 


(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


 




    5


     


    

 


(c) except as otherwise
provided in Sections 14(f)-(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, advance of Expenses, hold harmless
or exoneration payment, in its sole discretion, pursuant to the powers vested in the Company under applicable law. 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. INDEMNITOR
OF FIRST RESORT. The Company hereby acknowledges that Indemnitee may have certain rights to indemnification, advancement
of Expenses and/or insurance provided by one or more Persons with whom or which Indemnitee may be associated (collectively, the
“Alternative Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e.,
its obligations to Indemnitee are primary and any obligation of the Alternative Indemnitors to advance Expenses or to provide indemnification
for the same Expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full
amount of Expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, Fines
and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Certificate
of Incorporation or Bylaws of the Company (or any other agreement between the Company and Indemnitee), without regard to any rights
Indemnitee may have against the Alternative Indemnitors, and, (iii) that it irrevocably waives, relinquishes and releases the Alternative
Indemnitors from any and all claims against the Alternative Indemnitors for contribution, subrogation or any other recovery of
any kind in respect thereof. The Company further agrees that no advancement or payment by the Alternative Indemnitors on behalf
of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing
and the Alternative Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment
to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Alternative Indemnitors
are express third party beneficiaries of the terms of this Section 9.


 


10. ADVANCES
OF EXPENSES; DEFENSE OF CLAIM.


 


(a) Notwithstanding any
provision of this Agreement to the contrary (other than the provisions of Section 27 hereof), 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 (3) 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. This Section 10(a) shall not apply to any claim made by Indemnitee
for which an indemnification, advance of Expenses, hold harmless or exoneration payment is excluded pursuant to Section 8.


 


(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.


 




    6


     


    

 


1. PROCEDURE
FOR NOTIFICATION AND APPLICATION FOR INDEMNIFICATION.


 


(a) Indemnitee agrees
to promptly notify 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 Indemnitee’s 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, 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 or (ii) if there are no Disinterested Directors or if the Disinterested
Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee.
The Company will promptly 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 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 or law firm 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).


 




    7


     


    

 


(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 such Independent
Counsel’s 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 thirty-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 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 Indemnitee
reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that
Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful.


 


(d) For purposes of any
determination of good faith, Indemnitee 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, managers or officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise,
the 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, the 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, the Board, any committee of the Board or any director, trustee, general partner, manager
or managing member of the Enterprise. 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 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 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
7 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 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, 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, 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.


 


(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 Indemnitee’s 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).


 




    9


     


    

 


(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, 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.


 


(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, it is the intent of the parties hereto that Indemnitee shall
enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be
exclusive of any other right or remedy, and every other right and remedy 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 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 is or
was Serving 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.


 




    10


     


    

 


(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, (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.


 


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 is Serving 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.


 




    11


     


    

 


(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
to prove, 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 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

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 (including by electronic delivery of a counterpart
in pdf format), 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

24. MISCELLANEOUS.
Use of the masculine pronoun shall be deemed to include usage of the feminine pronoun where appropriate and vice versa. 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
(2) 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 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.
