Dear Paul,

 

We are pleased to confirm and memorialize
our agreement with you as President and Chief Executive Officer of JFL-NRC Holdings, L.L.C. (together with its subsidiaries and
successors and assigns, the “Company”), as follows:

 

		I.	Offices and Duties 

 

You shall serve as President and Chief
Executive Officer of the Company and be employed by National Response Corporation (“NRC”) starting by July 1, 2015.
You shall devote your full business time and attention and best efforts to the performance of your duties to the Company hereunder
without commitment to other business endeavors, provided however you may undertake and discharge such civic or charitable responsibilities
as you may assume from time-to-time during your employment with NRC. You shall perform such duties as are consistent with your
positions or as reasonably assigned to you by the Board of Directors, or equivalent, of the Company (the “Board”) from
time to time, as long as such assigned duties are reasonably consistent with your positions. You will be the most senior officer
of the Company. All other senior officers of the Company shall report directly to you (unless otherwise determined by the Board,
or as required by applicable law or the principles of good corporate governance).

 

Your employment with NRC is at will, which
means that either you or NRC can terminate your employment at any time for any reason, with or without cause and with or without
notice. This agreement as to at-will employment status sets forth the complete and exclusive agreement between you and NRC regarding
your employment status, and it supersedes any prior express or implied agreement or understanding between you and NRC regarding
that status, whether oral or in writing. You understand that your status as an at-will employee can be modified only in a written
agreement signed by an officer of NRC. Any notice of termination by NRC shall be communicated in writing.

		II.	Compensation

 

		(a)	Annual Base Salary:

 

Your annual salary compensation
will be set by the Compensation Committee of the Board and will initially be $325,000. Salary shall be payable in equal installments
in conformance with NRC’s regular payroll practices and dates for salaried personnel but no less frequently than monthly.

 

		(b)	Annual Bonus:

 

Your annual bonus for each calendar
year (“Annual Bonus”) will be set by the Compensation Committee of the Board and will be based upon attaining the annual
budget targets set by the Board. Your Annual Bonus will be paid within 15 days of completion of that year’s audit or at any
earlier time approved by the Compensation Committee of the Board, but in no event later than December 31 of the calendar year subsequent
to the calendar year to which such bonus relates. Your Annual Bonus is contingent upon your continued employment with NRC at the
time of payment (except as otherwise expressly provided for in this letter agreement).

 

The current Annual Bonus has two
components. The first component is based on the Company’s calendar year performance excluding the contribution of the U.S.
marine spill response business (“Base Annual Bonus”). The second component is based on the calendar year performance
of the U.S. marine spill response business (“NRC Response Annual Bonus”).

 

		(i)	Base Annual Bonus:

 

Your Base Annual Bonus will be
calculated as a percentage of your base salary (“Base Bonus Amount”), which Base Bonus Amount will be set by the Compensation
Committee of the Board and will be no less than 60% of your base salary. This percent is based 100% on the Company’s calendar
year performance (excluding the contribution of the U.S. marine spill response business) unless otherwise set by the Compensation
Committee of the Board. The applicable percentage of the Base Bonus Amount will be based (i) 60% on EBITDA performance, (ii) 30%
on free cash flow (defined as cash generated excluding any financing activities 3⁄4
e.g., the borrowing or repayment of debt), and (iii) 10% on the discretion of the Compensation Committee of the Board. EBITDA and
free cash flow will be determined based upon the audited financial results of the Company, consistently applied. The figures below
outline the scale that will be used to develop your Base Annual Bonus.

	 	125% of Target	 	=	 	 	150	%
	 	> 125% of Target	 	=	 	 	150	%

 

Payouts between 85% and 100%
performance and between 100% and 125% performance will be linear.

 

		(ii)	NRC Response Annual Bonus:

 

Your NRC Response Annual Bonus
will be calculated as a percentage of your salary (“NRC Response Bonus Amount”), which NRC Response Bonus Amount will
be set by the Compensation Committee of the Board and will be no less than 20% of your base salary. This percent is based 100%
on the Company’s U.S. marine spill response business performance unless otherwise set by the Compensation Committee of the
Board. The applicable percentage of the NRC Response Bonus Amount will be based (i) 60% on EBITDA performance, (ii) 30% on free
cash flow (defined as cash generated excluding any financing activities — e.g., the borrowing or repayment of debt), and
(iii) 10% on the discretion of the Compensation Committee of the Board. EBITDA and free cash flow will be determined based upon
the audited financial results of the Company, consistently applied. The figures below outline the scale that will be used to develop
your NRC Response Annual Bonus.

Payouts between 85% and 100%
performance and between 100% and 2,000% performance will be linear.

 

The Annual Bonus for 2015 will
be pro-rated for the portion of 2015 that you are employed.

		(d)	Equity Interests:

 

Within 60 days of your start date,
you will be granted as a profits interests a number of Class B Common Units initially equivalent, on the date you commence employment,

		(i)	Severability. The invalidity or unenforceability of any provision or provisions of this
Agreement shall not affect the validity or enforceability of any other provision of this letter agreement; and, in the event that
any one or more of the words, phrases, sentences, clauses, provisions, sections or articles contained in this letter agreement
shall be declared invalid, this letter agreement shall be construed as if such invalid word or words, phrase or phrases, sentence

of the expense reimbursement during any other taxable year, (ii) the expense reimbursement shall be made on or before the last
day of your taxable year following the year in which the expense was incurred and (iii) the right to expense reimbursement hereunder
shall not be subject to liquidation or exchange for another benefit.

FORM
OF

 

DIRECTOR
AND OFFICER INDEMNIFICATION AGREEMENT

 

This
Director and Officer Indemnification Agreement, dated as of _____________ (this “Agreement”), is made by and
between NRC Group Holdings Corp. (f/k/a Hennessy Capital Acquisition Corp. III), a Delaware corporation (the “Company”),
and _____________________ (“Indemnitee”).

 

RECITALS:

 

A.
Section 141 of the Delaware General Corporation Law provides that the business and affairs of a corporation shall be managed by
or under the direction of its board of directors.

 

B.
Pursuant to Sections 141 and 142 of the Delaware General Corporation Law, significant authority with respect to the management
of the Company has been delegated to the officers of the Company.

 

C.
By virtue of the managerial prerogatives vested in the directors and officers of a Delaware corporation, directors and officers
act as fiduciaries of the corporation and its stockholders.

 

D.
Thus, it is critically important to the Company and its stockholders that the Company be able to attract and retain the most capable
persons reasonably available to serve as directors and officers of the Company.

 

E.
In recognition of the need for corporations to be able to induce capable and responsible persons to accept positions in corporate
management, Delaware law authorizes (and in some instances requires) corporations to indemnify their directors and officers, and
further authorizes corporations to purchase and maintain insurance for the benefit of their directors and officers.

 

F.
The Delaware courts have recognized that indemnification by a corporation serves the dual policies of (1) allowing corporate officials
to resist unjustified lawsuits, secure in the knowledge that, if vindicated, the corporation will bear the expense of litigation
and (2) encouraging capable women and men to serve as corporate directors and officers, secure in the knowledge that the corporation
will absorb the costs of defending their honesty and integrity.

 

G.
The number of lawsuits challenging the judgment and actions of directors and officers of Delaware corporations, the costs of defending
those lawsuits, and the threat to directors’ and officers’ personal assets have all materially increased over the
past several years, chilling the willingness of capable women and men to undertake the responsibilities imposed on corporate directors
and officers.

 

H.
Federal legislation and rules adopted by the Securities and Exchange Commission and the national securities exchanges have imposed
additional disclosure and corporate governance obligations on directors and officers of public companies and have exposed such
directors and officers to new and substantially broadened civil liabilities.

 

     

     

    

 

I.
These legislative and regulatory initiatives have also exposed directors and officers of public companies to a significantly greater
risk of criminal proceedings, with attendant defense costs and potential criminal fines and penalties.

 

J.
Under Delaware law, a director’s or officer’s right to be reimbursed for the costs of defense of criminal actions,
whether such claims are asserted under state or federal law, does not depend upon the merits of the claims asserted against the
director or officer and is separate and distinct from any right to indemnification the director or officer may be able to establish,
and indemnification of the director or officer against criminal fines and penalties is permitted if the director or officer satisfies
the applicable standard of conduct.

 

K.
Indemnitee is a director or officer of the Company and his or her willingness to serve in such capacity is predicated, in substantial
part, upon the Company’s willingness to indemnify him or her in accordance with the principles reflected above, to the fullest
extent permitted by the laws of the state of Delaware, and upon the other undertakings set forth in this Agreement.

 

L.
Therefore, in recognition of the need to provide Indemnitee with substantial protection against personal liability, in order to
procure Indemnitee’s continued service as a director or officer of the Company and to enhance Indemnitee’s ability
to serve the Company in an effective manner, and in order to provide such protection pursuant to express contract rights (intended
to be enforceable irrespective of, among other things, any amendment to the Company’s certificate of incorporation or bylaws
(collectively, the “Constituent Documents”), any change in the composition of the Company’s Board of
Directors (the “Board”) or any change-in-control or business combination transaction relating to the Company),
the Company wishes to provide in this Agreement for the indemnification of and the advancement of Expenses (as defined in Section
1(f)) to Indemnitee as set forth in this Agreement and for the continued coverage of Indemnitee under the Company’s
directors’ and officers’ liability insurance policies.

 

M.
In light of the considerations referred to in the preceding recitals, it is the Company’s intention and desire that the
provisions of this Agreement be construed liberally, subject to their express terms, to maximize the protections to be provided
to Indemnitee hereunder.

by reason of an acquisition by the Company, and such person shall, after such acquisition by the Company, become the beneficial

interests in an entity or enterprise entitling the holder to cast 20% or more of the total number of votes generally entitled
to be cast in the election of directors (or persons performing comparable functions) of such entity or enterprise shall be deemed

approval of the proxy statement of the Company in which such person is named as a nominee for director, without objection to such
nomination); provided, however, that an individual shall not be an Incumbent Director if such individual’s election or appointment
to the Board occurs as a result of an actual or threatened election contest (as described in Rule 14a-12(c) of the Exchange Act)
with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on
behalf of a person other than the Board.

the Company, for purposes of this Agreement, Indemnitee shall be deemed to be serving or to have served at the request of the
Company as a director, officer, employee, member, manager, trustee or agent of another entity or enterprise if Indemnitee is or
was serving as a director, officer, employee, member, manager, trustee or agent of such entity or enterprise and (i) such entity
or enterprise is or at the time of such service was a Controlled Affiliate, (ii) such entity or enterprise is or at the time of

2.
Indemnification Obligation. Subject to Section 8, the Company shall indemnify, defend and hold harmless Indemnitee,
to the fullest extent permitted or required by the laws of the State of Delaware in effect on the date hereof or as such laws
may from time to time hereafter be amended to increase the scope of such permitted or required indemnification, against any and
all Indemnifiable Claims and Indemnifiable Losses; provided, however, that (a) except as provided in Sections
4 and 22, Indemnitee shall not be entitled to indemnification pursuant to this Agreement in connection with any Claim
initiated by Indemnitee against the Company or any director or officer of the Company unless the Company has joined in or consented
to the initiation of such Claim and (b) no repeal or amendment of any law of the State of Delaware shall in any way diminish or
adversely affect the rights of Indemnitee pursuant to this Agreement in respect of any occurrence or matter arising prior to any
such repeal or amendment.

 

3.
Advancement of Expenses. Indemnitee shall have the right to advancement by the Company prior to the final disposition of
any Indemnifiable Claim of any and all Expenses relating to, arising out of or resulting from any Indemnifiable Claim paid or
incurred by Indemnitee or which Indemnitee determines are reasonably likely to be paid or incurred by Indemnitee. Indemnitee’s
right to such advancement is not subject to the satisfaction of any standard of conduct and is not conditioned upon any prior
determination that Indemnitee is entitled to indemnification under this Agreement with respect to the Indemnifiable Claim or the
absence of any prior determination to the contrary. Without limiting the generality or effect of the foregoing, within five business
days after any request by Indemnitee, the Company shall, in accordance with such request (but without duplication), (a) pay such
Expenses on behalf of Indemnitee, (b) advance to Indemnitee funds in an amount sufficient to pay such Expenses, or (c) reimburse
Indemnitee for such Expenses; provided that Indemnitee shall repay, without interest any amounts actually advanced to Indemnitee
that, at the final disposition of the Indemnifiable Claim to which the advance related, were in excess of amounts paid or payable
by Indemnitee in respect of Expenses relating to, arising out of or resulting from such Indemnifiable Claim. In connection with
any such payment, advancement or reimbursement, if delivery of an undertaking is a legally required condition precedent to such
payment, advance or reimbursement, Indemnitee shall execute and deliver to the Company an undertaking in the form attached hereto
as Exhibit A (subject to Indemnitee filling in the blanks therein and selecting from among the bracketed alternatives therein),
which need not be secured and shall be accepted without reference to Indemnitee’s ability to repay the Expenses. In no event
shall Indemnitee’s right to the payment, advancement or reimbursement of Expenses pursuant to this Section 3 be conditioned
upon any undertaking that is less favorable to Indemnitee than, or that is in addition to, the undertaking set forth in Exhibit
A.

 

    	 	6	 

     

    

 

4.
Indemnification for Additional Expenses. Without limiting the generality or effect of the foregoing, the Company shall
indemnify and hold harmless Indemnitee against and, if requested by Indemnitee, shall reimburse Indemnitee for, or advance to
Indemnitee, within five business days of such request, any and all Expenses paid or incurred by Indemnitee or which Indemnitee
determines are reasonably likely to be paid or incurred by Indemnitee in connection with any Claim made, instituted or conducted
by Indemnitee for (a) indemnification or payment, advancement or reimbursement of Expenses by the Company under any provision
of this Agreement, or under any other agreement or provision of the Constituent Documents now or hereafter in effect relating
to Indemnifiable Claims, and/or (b) recovery under any directors’ and officers’ liability insurance policies maintained
by the Company, regardless in each case of whether Indemnitee ultimately is determined to be entitled to such indemnification,
reimbursement, advance or insurance recovery, as the case may be; provided, however, that Indemnitee shall return,
without interest, any such advance of Expenses (or portion thereof) which remains unspent at the final disposition of the Claim
to which the advance related.

 

5.
Contribution. To the fullest extent permissible under applicable law in effect on the date hereof or as such law may from
time to time hereafter be amended to increase the scope of permitted or required indemnification, if the indemnification provided
for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee,
shall contribute to the payment of any and all Indemnifiable Claims or Indemnifiable Losses, in such proportion as is fair and
reasonable in light of all of the circumstances in order to reflect (i) the relative benefits received by the Company and Indemnitee
as a result of the event(s) and/or transaction(s) giving cause to such Indemnifiable Claim or Indemnifiable Loss and/or (ii) the
relative fault of the Company (and its other directors, officers, employees and agents) and Indemnitee in connection with such
event(s) and/or transaction(s); provided that such contribution shall not be required where it is determined, pursuant
to a final disposition of such Indemnifiable Claim or Indemnifiable Loss in accordance with Section 8, that Indemnitee
is not entitled to indemnification by the Company with respect to such Indemnifiable Claim or Indemnifiable Loss.

 

6.
Partial Indemnity. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for
some or a portion of any Indemnifiable Loss, but not for all of the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion thereof to which Indemnitee is entitled.

 

7.
Procedure for Notification. To obtain indemnification under this Agreement in respect of an Indemnifiable Claim or Indemnifiable
Loss, Indemnitee shall submit to the Company a written request therefor, including a brief description (based upon information
then available to Indemnitee) of such Indemnifiable Claim or Indemnifiable Loss. If, at the time of the receipt of such request,
the Company has directors’ and officers’ liability insurance in effect under which coverage for such Indemnifiable
Claim or Indemnifiable Loss is potentially available, the Company shall give prompt written notice of such Indemnifiable Claim
or Indemnifiable Loss to the applicable insurers in accordance with the procedures set forth in the applicable policies. The Company
shall provide to Indemnitee a copy of such notice delivered to the applicable insurers, and copies of all subsequent correspondence
between the Company and such insurers regarding the Indemnifiable Claim or Indemnifiable Loss, in each case substantially concurrently
with the delivery or receipt thereof by the Company. The failure by Indemnitee to timely notify the Company of any Indemnifiable
Claim or Indemnifiable Loss shall not relieve the Company from any liability hereunder unless, and only to the extent that, the
Company did not otherwise learn of such Indemnifiable Claim or Indemnifiable Loss and such failure results in forfeiture by the
Company of substantial defenses, rights or insurance coverage.

 

    	 	7	 

     

    

 

8.
Determination of Right to Indemnification.

 

(a)
To the extent that Indemnitee shall have been successful on the merits or otherwise in defense of any Indemnifiable Claim or any
portion thereof or in defense of any issue or matter therein, including dismissal without prejudice, Indemnitee shall be indemnified
against Indemnifiable Losses relating to, arising out of or resulting from such Indemnifiable Claim in accordance with Section
2 and no Standard of Conduct Determination (as defined in Section 8(c)) shall be required.

 

(b)
After a Change in Control (other than a Change in Control approved by a majority of the Board (including a majority of Incumbent
Directors), the determination of whether Indemnitee has satisfied any applicable standard of conduct under Delaware law that is
a legally required condition precedent to indemnification of Indemnitee hereunder shall be made by Independent Counsel, selected
by the Board, subject to the consent of Indemnitee, which consent shall only be withheld if Independent Counsel selected by the
Board does not meet the requirements set forth in the definition of “Independent Counsel.” With respect to
all matters arising from such a Change in Control concerning the rights of the Indemnitee to indemnity payments and Expense advances
under this agreement or any other agreement or under applicable law or the Constituent Documents now or hereafter in effect relating
to indemnification for purported Indemnifiable Claims, the Company shall seek legal advice only from Independent Counsel. Such
counsel, among other things, shall render its written opinion to the Board and Indemnitee as to whether and to what extent the
Indemnitee should be indemnified under applicable law.

 

(c)
To the extent that the provisions of Section 8(a) and Section 8(b) are inapplicable to an Indemnifiable Claim that
shall have been finally disposed of, any determination of whether Indemnitee has satisfied any applicable standard of conduct
under Delaware law that is a legally required condition precedent to indemnification of Indemnitee hereunder against Indemnifiable
Losses relating to, arising out of or resulting from such Indemnifiable Claim (a “Standard of Conduct Determination”)
shall be made as follows: (i) by a majority vote of the Disinterested Directors, even if less than a quorum of the Board; (ii)
if such Disinterested Directors so direct, by a majority vote of a committee of Disinterested Directors designated by a majority
vote of all Disinterested Directors; or (iii) if there are no such Disinterested Directors or if Indemnitee so requests, by Independent
Counsel, selected by the Indemnitee and approved by the Board (such approval not to be unreasonably withheld, delayed or conditioned),
in a written opinion addressed to the Board, a copy of which shall be delivered to Indemnitee. Indemnitee will cooperate with
the person or persons making such Standard of Conduct Determination, including providing to such person or persons, 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. The Company shall indemnify and hold harmless
Indemnitee against and, if requested by Indemnitee, shall reimburse Indemnitee for, or advance to Indemnitee, within five business
days of such request, any and all costs and expenses (including attorneys’ and experts’ fees and expenses) incurred
by Indemnitee in so cooperating with the person or persons making such Standard of Conduct Determination.

 

    	 	8	 

     

    

 

(d)
The Company shall use its reasonable best efforts to cause any Standard of Conduct Determination required under Section 8(c)
to be made as promptly as practicable. If (i) the person or persons empowered or selected under Section 8(c) to
make the Standard of Conduct Determination shall not have made a determination within 30 days after the later of (A) receipt
by the Company of written notice from Indemnitee advising the Company of the final disposition of the applicable Indemnifiable
Claim (the date of such receipt being the “Notification Date”) and (B) the selection of an Independent Counsel,
if such determination is to be made by Independent Counsel, and (ii) Indemnitee shall have fulfilled his or her obligations set
forth in the second sentence of Section 8(c), then Indemnitee shall be deemed to have satisfied the applicable standard
of conduct; provided that such 30-day period may be extended for a reasonable time, not to exceed an additional 30 days,
if the person or persons making such determination in good faith requires such additional time for the obtaining or evaluation
or documentation and/or information relating thereto.

 

(e)
If (i) Indemnitee shall be entitled to indemnification hereunder against any Indemnifiable Losses pursuant to Section 8(a),
(ii) no determination of whether Indemnitee has satisfied any applicable standard of conduct under Delaware law is a legally required
condition precedent to indemnification of Indemnitee hereunder against any Indemnifiable Losses, or (iii) Indemnitee has
been determined or deemed pursuant to Section 8(c) or (d) to have satisfied any applicable standard of conduct under
Delaware law which is a legally required condition precedent to indemnification of Indemnitee hereunder against any Indemnifiable
Losses, then the Company shall pay to Indemnitee, within five business days after the later of (x) the Notification Date in respect
of the Indemnifiable Claim or portion thereof to which such Indemnifiable Losses are related, out of which such Indemnifiable
Losses arose or from which such Indemnifiable Losses resulted, and (y) the earliest date on which the applicable criterion specified
in clause (i), (ii) or (iii) above shall have been satisfied, an amount equal to the amount of such Indemnifiable Losses.

 

9.
Presumption of Entitlement.

 

(a)
In making any Standard of Conduct Determination, the person or persons making such determination shall presume that Indemnitee
has satisfied the applicable standard of conduct, and the Company may overcome such presumption only by its adducing clear and
convincing evidence to the contrary. Any Standard of Conduct Determination that is adverse to Indemnitee may be challenged by
Indemnitee in the Court of Chancery of the State of Delaware. No determination by the Company (including by its directors or any
Independent Counsel) that Indemnitee has not satisfied any applicable standard of conduct shall be a defense to any Claim by Indemnitee
for indemnification or reimbursement or advance payment of Expenses by the Company hereunder or create a presumption that Indemnitee
has not met any applicable standard of conduct.

 

(b)
Without limiting the generality or effect of Section 9(a), (i) to the extent that any Indemnifiable Claim relates to any
entity or enterprise referred to in clause (i) of the first sentence of the definition of “Indemnifiable Claim,”
Indemnitee shall be deemed to have satisfied the applicable standard of conduct if Indemnitee acted in good faith and in a manner
Indemnitee reasonably believed to be in or not opposed to the interests of such entity or enterprise (or the owners or beneficiaries
thereof, including in the case of any employee benefit plan the participants and beneficiaries thereof) and, with respect to any
criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful, and (ii) in all cases,
any belief of Indemnitee that is based on the records or books of account of the Company, including financial statements, or on
information supplied to Indemnitee by the directors or officers of the Company in the course of their duties, or on the advice
of legal counsel for the Company, its Board, any committee of the Board or any director, or on information or records given or
reports made to the Company, its Board, any committee of the Board or any director by an independent certified public accountant
or by an appraiser or other expert selected by or on behalf of the Company, its Board, any committee of the Board or any director
shall be deemed to be reasonable.

10.
No Adverse Presumption. For purposes of this Agreement, the termination of any Claim by judgment, order, settlement (whether
with or without court approval) or conviction, or upon a plea of nolo contendere or its equivalent, will not create a presumption
that Indemnitee did not meet any applicable standard of conduct or that indemnification hereunder is otherwise not permitted.

 

11.
Non-Exclusivity. The rights of Indemnitee hereunder will be in addition to any other rights Indemnitee may have under the
Constituent Documents, or the substantive laws of the Company’s jurisdiction of incorporation, any other contract or otherwise
(collectively, “Other Indemnity Provisions”); provided, however, that (a) to the extent that
Indemnitee otherwise would have any greater right to indemnification under any Other Indemnity Provision, Indemnitee will be deemed
to have such greater right hereunder and (b) to the extent that any change is made to any Other Indemnity Provision which permits
any greater right to indemnification than that provided under this Agreement as of the date hereof, Indemnitee will be deemed
to have such greater right hereunder. If the Indemnitee is entitled to indemnification under certain agreements containing indemnity
provisions with another entity or protections under the organization documents of such other entity, the Company is still wholly
liable for making any indemnification payments for all Indemnifiable Claims or Indemnifiable Losses notwithstanding the payment
obligation of such amounts by a third party to the Indemnitee. The Company will not adopt any amendment to any of the Constituent
Documents the effect of which would be to deny, diminish or encumber Indemnitee’s right to indemnification under this Agreement
or any Other Indemnity Provision.

 

12.
Liability Insurance and Funding. For the duration of Indemnitee’s service as a director and/or officer of the Company,
and thereafter for so long as Indemnitee shall be subject to any pending or possible Indemnifiable Claim, the Company shall use
commercially reasonable efforts (taking into account the scope and amount of coverage available relative to the cost thereof)
to cause to be maintained in effect policies of directors’ and officers’ liability insurance providing coverage for
directors and/or officers of the Company that is at least substantially comparable in scope and amount to that provided by the
Company’s current policies of directors’ and officers’ liability insurance. The Company shall provide Indemnitee
with a copy of all directors’ and officers’ liability insurance applications, binders, policies, declarations, endorsements
and other related materials, and shall provide Indemnitee with a reasonable opportunity to review and comment on the same. Without
limiting the generality or effect of the two immediately preceding sentences, the Company shall not discontinue or significantly
reduce the scope or amount of coverage from one policy period to the next (a) without the prior approval thereof by a majority
vote of the Incumbent Directors, even if less than a quorum, or (b) if at the time that any such discontinuation or significant
reduction in the scope or amount of coverage is proposed there are no Incumbent Directors, without the prior written consent of
Indemnitee (which consent shall not be unreasonably withheld or delayed). In all policies of directors’ and officers’
liability insurance obtained by the Company, Indemnitee shall be named as an insured in such a manner as to provide Indemnitee
the same rights and benefits, subject to the same limitations, as are accorded to the Company’s directors and officers most
favorably insured by such policy. The Company may, but shall not be required to, create a trust fund, grant a security interest
or use other means, including a letter of credit, to ensure the payment of such amounts as may be necessary to satisfy its obligations
to indemnify and advance expenses pursuant to this Agreement.

 

    	 	10	 

     

    

  

13.
Subrogation. In the event of payment under this Agreement, the Company shall be subrogated to the extent of such payment
to all of the related rights of recovery of Indemnitee against other persons or entities (other than Indemnitee’s successors),
including any entity or enterprise referred to in clause (i) of the definition of “Indemnifiable Claim” in
Section 1(h). Indemnitee shall execute all papers reasonably required to evidence such rights (all of Indemnitee’s
reasonable Expenses, including attorneys’ fees and charges, related thereto to be reimbursed by or, at the option of Indemnitee,
advanced by the Company).

 

14.
No Duplication of Payments. The Company shall not be liable under this Agreement to make any payment to Indemnitee in respect
of any Indemnifiable Losses to the extent Indemnitee has otherwise actually received payment (net of any Expenses incurred in
connection therewith and any repayment by Indemnitee made with respect thereto) under any insurance policy, the Constituent Documents
and Other Indemnity Provisions or otherwise (including from any entity or enterprise referred to in clause (i) of the definition
of “Indemnifiable Claim” in Section 1(h)) in respect of such Indemnifiable Losses otherwise indemnifiable
hereunder.

 

15.
Defense of Claims. The Company shall be entitled to participate in the defense of any Indemnifiable Claim or to assume
the defense thereof, with counsel reasonably satisfactory to Indemnitee; provided that if Indemnitee believes, after consultation
with counsel selected by Indemnitee, that (a) the use of counsel chosen by the Company to represent Indemnitee would present such
counsel with an actual or potential conflict, (b) the named parties in any such Indemnifiable Claim (including any impleaded parties)
include both the Company and Indemnitee and Indemnitee shall conclude that there may be one or more legal defenses available to
him or her that are different from or in addition to those available to the Company, or (c) any such representation by such counsel
would be precluded under the applicable standards of professional conduct then prevailing, the Indemnitee shall be entitled to
retain separate counsel (but not more than one law firm plus, if applicable, local counsel in respect of any particular Indemnifiable
Claim) at the Company’s expense. The Company shall not be liable to Indemnitee under this Agreement for any amounts paid
in settlement of any threatened or pending Indemnifiable Claim effected without the Company’s prior written consent. The
Company shall not, without the prior written consent of Indemnitee, effect any settlement of any threatened or pending Indemnifiable
Claim to which Indemnitee is, or could have been, a party unless such settlement solely involves the payment of money and includes
a complete and unconditional release of Indemnitee from all liability on any claims that are the subject matter of such Indemnifiable
Claim. Neither the Company nor Indemnitee shall unreasonably withhold its consent to any proposed settlement; provided
that Indemnitee may withhold consent to any settlement that does not provide a complete and unconditional release of Indemnitee.

 

    	 	11	 

     

    

  

16.
Liability of Company. Indemnitee agrees that neither the stockholders nor the directors nor any officer, employee, representative
or agent of the Company shall be personally liable for the satisfaction of the Company’s obligations under this Agreement
and Indemnitee shall look solely to the assets of the Company for satisfaction of any claims hereunder.

 

17.
Successors and Binding Agreement.

 

(a)
The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation, reorganization or otherwise)
to all or substantially all of the business or assets of the Company, by agreement in form and substance satisfactory to Indemnitee
and his or her counsel, expressly to assume and agree to perform this Agreement in the same manner and to the same extent the
Company would be required to perform if no such succession had taken place. This Agreement shall be binding upon and inure to
the benefit of the Company and any successor to the Company, including any person acquiring directly or indirectly all or substantially
all of the business or assets of the Company whether by purchase, merger, consolidation, reorganization or otherwise (and such
successor will thereafter be deemed the “Company” for purposes of this Agreement), but shall not otherwise
be assignable or delegable by the Company.

 

(b)
This Agreement shall inure to the benefit of and be enforceable by Indemnitee’s personal or legal representatives, executors,
administrators, heirs, distributees, legatees and other successors.

 

(c)
This Agreement is personal in nature and neither of the parties hereto shall, without the consent of the other, assign or delegate
this Agreement or any rights or obligations hereunder except as expressly provided in Sections 17(a) and 17(b).
Without limiting the generality or effect of the foregoing, Indemnitee’s right to receive payments hereunder shall not be
assignable, whether by pledge, creation of a security interest or otherwise, other than by a transfer by Indemnitee’s will
or by the laws of descent and distribution, and, in the event of any attempted assignment or transfer contrary to this Section
17(c), the Company shall have no liability to pay any amount so attempted to be assigned or transferred.

 

18.
Notices. For all purposes of this Agreement, all communications, including notices, consents, requests or approvals, required
or permitted to be given hereunder shall be in writing and shall be deemed to have been duly given when hand delivered or on the
date sent if delivered by email so long as such communication is furnished to a nationally recognized overnight courier for next
business day delivery or five business days after having been mailed by United States registered or certified mail, return receipt
requested, postage prepaid or one business day after having been sent for next-day delivery by a nationally recognized overnight
courier service, addressed to the Company (to the attention of the secretary of the Company) and to Indemnitee at the applicable
address shown on the signature page hereto, or to such other address as any party may have furnished to the other in writing and
in accordance herewith, except that notices of changes of address will be effective only upon receipt.

19.
Governing Law. The validity, interpretation, construction and performance of this Agreement shall be governed by and construed
in accordance with the substantive laws of the State of Delaware, without giving effect to the principles of conflict of laws
of such State. The Company and Indemnitee each hereby irrevocably consent to the jurisdiction of the Chancery Court of the State
of Delaware for all purposes in connection with any action or proceeding which arises out of or relates to this Agreement and
agree that any action instituted under this Agreement shall be brought only in the Chancery Court of the State of Delaware.

 

20.
Validity. If any provision of this Agreement or the application of any provision hereof to any person or circumstance is
held invalid, unenforceable or otherwise illegal, the remainder of this Agreement and the application of such provision to any
other person or circumstance shall not be affected, and the provision so held to be invalid, unenforceable or otherwise illegal
shall be reformed to the extent, and only to the extent, necessary to make it enforceable, valid or legal. In the event that any
court or other adjudicative body shall decline to reform any provision of this Agreement held to be invalid, unenforceable or
otherwise illegal as contemplated by the immediately preceding sentence, the parties thereto shall take all such action as may
be necessary or appropriate to replace the provision so held to be invalid, unenforceable or otherwise illegal with one or more
alternative provisions that effectuate the purpose and intent of the original provisions of this Agreement as fully as possible
without being invalid, unenforceable or otherwise illegal.

 

21.
Miscellaneous. No provision of this Agreement may be waived, modified or discharged unless such waiver, modification or
discharge is agreed to in writing signed by Indemnitee and the Company. No waiver by either party hereto at any time of any breach
by the other party hereto or compliance with any condition or provision of this Agreement to be performed by such other party
shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No
agreements or representations, oral or otherwise, expressed or implied with respect to the subject matter hereof have been made
by either party that are not set forth expressly in this Agreement. References to Sections are references to Sections of this
Agreement.

 

22.
Legal Fees and Expenses; Interest.

 

(a)
It is the intent of the Company that Indemnitee not be required to incur legal fees and/or other Expenses associated with the
interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or otherwise because the
cost and expense thereof would substantially detract from the benefits intended to be extended to Indemnitee hereunder. Accordingly,
without limiting the generality or effect of any other provision hereof, if it should appear to Indemnitee that the Company has
failed to comply with any of its obligations under this Agreement (including its obligations under Section 3) or in the
event that the Company or any other person takes or threatens to take any action to declare this Agreement void or unenforceable,
or institutes any litigation or other action or proceeding designed to deny, or to recover from, Indemnitee the benefits provided
or intended to be provided to Indemnitee hereunder, the Company irrevocably authorizes Indemnitee from time to time to retain
counsel of Indemnitee’s choice, at the expense of the Company as hereafter provided, to advise and represent Indemnitee
in connection with any such interpretation, enforcement or defense, including the initiation or defense of any litigation or other
legal action, whether by or against the Company or any director, officer, stockholder or other person affiliated with the Company,
in any jurisdiction. Notwithstanding any existing or prior attorney-client relationship between the Company and such counsel,
the Company irrevocably consents to Indemnitee’s entering into an attorney-client relationship with such counsel, and in
that connection the Company and Indemnitee agree that a confidential relationship shall exist between Indemnitee and such counsel.
Without respect to whether Indemnitee prevails, in whole or in part, in connection with any of the foregoing, the Company will
pay and be solely financially responsible for any and all attorneys’ and related fees and expenses incurred by Indemnitee
in connection with any of the foregoing to the fullest extent permitted or required by the laws of the State of Delaware in effect
on the date hereof or as such laws may from time to time hereafter be amended to increase the scope of such permitted or required
payment of such fees and expenses.

 

    	 	13	 

     

    

 

(b)
Any amount due to Indemnitee under this Agreement that is not paid by the Company by the date on which it is due will accrue interest
at the maximum legal rate under Delaware law from the date on which such amount is due to the date on which such amount is paid
to Indemnitee.

 

23.
Certain Interpretive Matters. Unless the context of this Agreement otherwise requires, (a) “it” or “its”
or words of any gender include each other gender, (b) words using the singular or plural number also include the plural or singular
number, respectively, (c) the terms “hereof,” “herein,” “hereby” and derivative or similar
words refer to this entire Agreement, (d) the terms “Article,” “Section,” “Annex” or
“Exhibit” refer to the specified Article, Section, Annex or Exhibit of or to this Agreement, (e) the terms “include,”
“includes” and “including” will be deemed to be followed by the words “without limitation”
(whether or not so expressed), and (f) the word “or” is disjunctive but not exclusive. Whenever this Agreement refers
to a number of days, such number will refer to calendar days unless business days are specified and whenever action must be taken
(including the giving of notice or the delivery of documents) under this Agreement during a certain period of time or by a particular
date that ends or occurs on a non-business day, then such period or date will be extended until the immediately following business
day. As used herein, “business day” means any day other than Saturday, Sunday or a United States federal holiday.
Any reference to a law shall include any amendment thereof or any successor thereto and any rules and regulations promulgated
thereunder. Any reference to a contract is a reference to it as amended, modified and supplemented from time to time.

 

24.
Counterparts. This Agreement may be executed in counterparts, each of which will be deemed to be an original but all of
which together shall constitute one and the same agreement.
