Exhibit 10.7


 


INDEMNITY AGREEMENT


 





THIS INDEMNITY AGREEMENT (this
“Agreement”) is made as of [            ], 2018,
by and between Nebula Acquisition Corporation, a Delaware corporation (the “Company”), and [           
] (“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. Although the furnishing of such insurance has been a
customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that,
given current market conditions and trends, such insurance may be available to it in the future only at higher premiums and with
more exclusions. At the same time, directors, officers and other persons in service to corporations or business enterprises are
being increasingly subjected to expensive and time-consuming litigation relating to, among other things, matters that traditionally
would have been brought only against the Company or business enterprise itself.  The 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 of the Company and any resolutions adopted pursuant
thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder;


 


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; and


 


NOW, THEREFORE,
in consideration of the premises and the covenants contained herein and subject to the provisions of the letter agreement dated
as of [               ], 2018, the Company and Indemnitee do hereby covenant and agree as follows:

as Indemnitee is duly elected or appointed or retained 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, officer, advisor, key employee or in any other capacity of the Company, as provided in Section 17.

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

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

Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. No indemnification, hold harmless
or exoneration for Expenses shall be made under this Section 4 in respect of any claim, issue or matter as to which Indemnitee
shall have been finally adjudged by a court to be liable to the Company, unless and only to the extent that any court in which
the Proceeding was brought or the Delaware Court shall determine upon application that, despite the adjudication of liability
but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification, to be
held harmless or to exoneration.

5. INDEMNIFICATION
FOR EXPENSES OF A PARTY WHO IS WHOLLY OR PARTLY SUCCESSFUL. Notwithstanding any other provisions of this Agreement 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

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.


 


7. ADDITIONAL
INDEMNIFICATION, HOLD HARMLESS AND EXONERATION RIGHTS.


 


(a) 
Notwithstanding any limitation in Sections 3, 4, or 5, 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, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable
in connection with or in respect of such Expenses, judgments, fines, penalties and amounts paid in settlement) actually and reasonably
incurred by Indemnitee in connection with the Proceeding. No indemnification, hold harmless or exoneration rights shall be available
under this Section 7(a) on account of Indemnitee’s conduct which constitutes a breach of Indemnitee’s duty
of loyalty to the Company or its stockholders or is an act or omission not in good faith or which involves intentional misconduct
or a knowing violation of the law.


 


(b) 
Notwithstanding any limitation in Sections 3, 4, 5 or 7(a), 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, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges
paid or payable in connection with or in respect of such Expenses, judgments, fines, penalties and amounts paid in settlement)
actually and reasonably incurred by Indemnitee in connection with the Proceeding.


 


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.


 






    	 	5	 



     


    

 


(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.


 


9. EXCLUSIONS.
Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnification,
advance expenses, hold harmless or exoneration payment in connection with any claim made against Indemnitee:


 


(a) 
for which payment has actually been received by or on behalf of Indemnitee under any insurance policy or other indemnity or advancement
provision, except with respect to any excess beyond the amount actually received under any insurance policy, contract, agreement,
other indemnity or advancement provision or otherwise;


 


(b) 
for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company
within the meaning of Section 16(b) of the Exchange Act (or any successor rule) or similar provisions of state statutory
law or common law; or


 


(c) 
except as otherwise provided in Sections 14(f)-(g) hereof, prior to a Change in Control, in connection with any Proceeding
(or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated
by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board authorized
the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, hold
harmless or exoneration payment, in its sole discretion, pursuant to the powers vested in the Company under applicable law. 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.


 


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 of the Company, applicable law or otherwise. This Section 10(a) shall not apply to any claim
made by Indemnitee for which an indemnification, hold harmless or exoneration payment is excluded pursuant to Section 9.


 


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


 


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

11. PROCEDURE
FOR NOTIFICATION AND APPLICATION FOR INDEMNIFICATION.


 


(a) 
Indemnitee agrees to notify promptly the Company in writing upon being served with any summons, citation, subpoena, complaint,
indictment, information or other document relating to any Proceeding, claim, issue or matter therein which may be subject to indemnification,
hold harmless or exoneration rights, or advancement of Expenses covered hereunder. The failure of Indemnitee to so notify the Company
shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement, or otherwise.


 


(b) 
Indemnitee may deliver to the Company a written application to indemnify, hold harmless or exonerate Indemnitee in accordance with
this Agreement. Such application(s) may be delivered from time to time and at such time(s) as Indemnitee deems appropriate
in his 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, (ii) by a committee of such directors designated
by majority vote of such directors, (iii) if there are no Disinterested Directors or if such directors so direct, by Independent
Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee, or (iv) by vote of the stockholders.
The Company promptly will advise Indemnitee in writing with respect to any determination that Indemnitee is or is not entitled
to indemnification, including a description of any reason or basis for which indemnification has been denied. If it is so determined
that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days after such determination.
Indemnitee shall reasonably cooperate with the person, persons or entity making such determination with respect to Indemnitee’s
entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation
or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and
reasonably necessary to such determination. Any costs or Expenses (including reasonable attorneys’ fees and disbursements)
incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company
(irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby agrees to indemnify
and to hold Indemnitee harmless therefrom.


 


(b) 
In the event the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 12(a) hereof,
the Independent Counsel shall be selected as provided in this Section 12(b). The Independent Counsel shall be selected by
Indemnitee (unless Indemnitee shall request that such selection be made by the Board), and Indemnitee shall give written notice
to the Company advising it of the identity of the Independent Counsel so selected and certifying that the Independent Counsel so
selected meets the requirements of “Independent Counsel” as defined in Section 2 of this Agreement. If the Independent
Counsel is selected by the Board, the Company shall give written notice to Indemnitee advising 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).


 






    	 	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 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 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, manager, or officers of the Enterprise in the course of their duties, or on the advice of legal
counsel for the Enterprise, its Board, any committee of the Board or any director, trustee, general partner, manager or managing
member, or on information or records given or reports made to the Enterprise, its Board, any committee of the Board or any director,
trustee, general partner, manager or managing member, by an independent certified public accountant or by an appraiser or other
expert selected by the Enterprise, its Board, any committee of the Board or any director, trustee, general partner, manager or
managing member. The provisions of this Section 13(d) shall not be deemed to be exclusive or to limit in any way the
other circumstances in which Indemnitee may be deemed or found to have met the applicable standard of conduct set forth in this
Agreement.


 


(e) 
The knowledge and/or actions, or failure to act, of any other director, officer, trustee, partner, manager, managing member, fiduciary,
agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification
under this Agreement.

14. REMEDIES
OF INDEMNITEE.


 


(a) 
In the event that (i) a determination is made pursuant to Section 12 of this Agreement that Indemnitee is not entitled
to indemnification under this Agreement, (ii) advancement of Expenses, to the fullest extent permitted by applicable law,
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 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 his 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, 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.


 


(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 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.


 






    	 	10	 



     


    

 


(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.


 


(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 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.


 


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 of the Company as they may be amended from time to
time, this Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and
supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject
matter hereof.


 


(c) 
The indemnification, hold harmless, exoneration and advancement of expenses rights provided by or granted pursuant to this Agreement
shall be binding upon and be enforceable by the parties hereto and their respective successors and assigns (including any direct
or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business and/or assets
of the Company), shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company
or a director, officer, trustee, general partner, manager, managing member, fiduciary, employee or agent of any other Enterprise
at the Company’s request, and shall inure to the benefit of Indemnitee and 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 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 arising out of or in connection with this Agreement; (c) waive
any objection to the laying of venue of any such action or proceeding in the Delaware Court; and (d) waive, and agree not
to plead or to make, any claim that any such action or proceeding brought in the Delaware Court has been brought in an improper
or inconvenient forum, or is subject (in whole or in part) to a jury trial. To the fullest extent 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 whom enforceability is sought needs to be produced to evidence the existence of this Agreement.


 


24. MISCELLANEOUS.
Use of the masculine pronoun shall be deemed to include usage of the feminine pronoun where appropriate. The headings of the paragraphs
of this Agreement are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect the
construction thereof.


 


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


 


26. ADDITIONAL
ACTS. If for the validation of any of the provisions in this Agreement any act, resolution, approval or other procedure is
required to the fullest extent permitted by 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. 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.


 


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.
