Ladies
and Gentlemen:

 

This
letter agreement (this “Agreement”) relates to a Purchase Agreement entered into as of June 25, 2018 (“Purchase
Agreement”) by and between Hennessy Capital Acquisition Corp. III, a Delaware corporation (“Purchaser”),
and JFL-NRC-SES Partners, LLC, a Delaware limited liability company. Capitalized terms used and not otherwise defined herein are
defined in the Purchase Agreement and shall have the meanings given to such terms in the Purchase Agreement.

 

1.  In
order to induce all parties to consummate the transactions contemplated by the Purchase Agreement, the undersigned hereby agrees
that, from the date hereof until the earliest of: (a) the 180th day after the Closing Date, (b) the date
following the completion of the transactions contemplated by the Purchase Agreement on which Purchaser completes a liquidation,
merger, stock exchange or other similar transaction that results in all of Purchaser’s stockholders having the right to
exchange their shares of Purchaser Common Stock for cash, securities or other property and (c) the Alternative Lock-up Termination
Date (as defined in the Exchange and Forfeiture Agreement) (the period between the Closing Date and the earliest of clauses (a),
(b) and (c), the “Lock-Up Period”), the undersigned will not: (i) sell, offer to sell, contract or agree
to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly,
or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16
of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Securities and Exchange Commission promulgated
thereunder (the “Exchange Act”), with respect to the shares of Purchaser Common Stock received as Purchase
Price Common Stock pursuant to the Purchase Agreement (such shares, collectively, the “Lock-up Shares”), (ii) enter
into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership
of any of the Lock-up Shares, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified
in clause (i) or (ii).

 

2.  The
undersigned hereby authorizes Purchaser during the Lock-Up Period to cause its transfer agent for the Lock-up Shares to decline
to transfer, and to note stop transfer restrictions on the stock register and other records relating to, Lock-up Shares for which
the undersigned is the record holder and, in the case of Lock-up Shares for which the undersigned is the beneficial but not the
record holder, agrees during the Lock-Up Period to cause the record holder to cause the relevant transfer agent to decline to
transfer, and to note stop transfer restrictions on the stock register and other records relating to, such Lock-up Shares, if
such transfer would constitute a violation or breach of this Agreement.

 

    

    

    

 

3.  Notwithstanding
the foregoing, the undersigned may sell or otherwise transfer Lock-up Shares during the undersigned’s lifetime or on death
(or, if the undersigned is not a natural person, during its existence) (i) if the undersigned is not a natural person, to
its direct or indirect equity holders or to any of its other Affiliates, (ii) to the immediate family members (including
spouses, significant others, lineal descendants, brothers and sisters) of the undersigned, (iii) to a family trust, foundation
or partnership established for the exclusive benefit of the undersigned, its equity holders or any of their respective immediate
family members, or (iv) to a charitable foundation controlled by the undersigned, its equityholders or any of their respective
immediate family members; provided, however, that in each such case, any such sale or transfer shall be conditioned upon entry
by such transferees into a written agreement, addressed to Purchaser, agreeing to be bound by these transfer restrictions and
the other terms and conditions of this Agreement.

  

4.  The
undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Agreement and
that this Agreement constitutes the legal, valid and binding obligation of the undersigned, enforceable in accordance with its
terms. Upon request, the undersigned will execute any additional documents necessary in connection with enforcement hereof. Any
obligations of the undersigned shall be binding upon the successors and assigns of the undersigned from the date first above written.

 

5.  This
Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and
supersedes all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent
they relate in any way to the subject matter hereof. This Agreement may not be changed, amended, modified or waived (other than
to correct a typographical error) as to any particular provision, except by a written instrument executed by all parties hereto.

 

6.  No
party hereto may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written
consent of the other party. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not
operate to transfer or assign any interest or title to the purported assignee. This Agreement shall be binding on the undersigned
and its successors and assigns.

 

7.  This
Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware, without giving
effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The
parties hereto (i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this
Agreement shall be brought and enforced in the Court of Chancery of the State of Delaware (or, if the Court of Chancery of the
State of Delaware lacks jurisdiction, then in the applicable Delaware state court), or if under applicable Law exclusive jurisdiction
of such action is vested in the federal courts, then the United States District Court for the District of Delaware courts, and
irrevocably submits to such jurisdiction and venue, which jurisdiction and venue shall be exclusive, and (ii) waives any
objection to such exclusive jurisdiction and venue or that such courts represent an inconvenient forum.

 

8.  Any
notice, consent or request to be given in connection with any of the terms or provisions of this Agreement shall be in writing
and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested) or email transmission

NOW,
THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties
agree as follows:

 

1.  Definitions.
As used in this Agreement, the following terms shall have the meanings ascribed to them below:

 

(a)  “Affiliate”
means, with respect to any specified Person, any other Person who, directly or indirectly, controls, is controlled by, or is under
common control with such Person.

 

(b)  “beneficially
own” shall have the meaning ascribed to such term under Rule 13d-3 of the Exchange Act.

 

(c)  “Bylaws”
means the Amended and Restated Bylaws of the Company, as may be amended from time to time.

 

(d)  “Certificate
of Incorporation” means the Second Amended and Restated Certificate of Incorporation of the Company, as may be amended
from time to time.

 

(e)  “DGCL”
means the General Corporation Law of the State of Delaware, as amended from time to time.

(g)  “Exchange
Act” means the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder.

 

(h)  “Person”
means a natural person or any legal, commercial or governmental entity, such as, but not limited to, a corporation, general partnership,
joint venture, limited partnership, limited liability company, limited liability partnership, trust, business association, group
acting in concert, or any person acting in a representative capacity.

 

(i)  “Total
Number of Directors” means the total number of directors constituting the Board.

 

2.  Board
Nominations.1

 

(a)  

 

(i)  Following
the Effective Date, JFLCo (on behalf of each JFL entity that owns JFL Shares or any other shares of capital stock of the Company)
shall have the right (but not the obligation) pursuant to this Section 2 to nominate to the Board at every meeting of the stockholders
of the Company in which directors are elected, including, without limitation, at every adjournment or postponement thereof, and
on any action approval by written consent of the stockholders of the Company relating to the election of directors, a number of
designees equal to at least: (i) a majority of the Total Number of Directors, so long as JFL collectively beneficially own 50%
or more of the shares of Common Stock; (ii) 50% of the Total Number of Directors, in the event that JFL collectively beneficially
own 40% or more, but less than 50%, of the shares of Common Stock; (iii) 40% of the Total Number of Directors, in the event
that JFL collectively beneficially own 30% or more, but less than 40%, of the shares of Common Stock; (iv) 30% of the Total
Number of Directors, in the event that JFL collectively beneficially own 15% or more, but less than 30%, of the shares of Common
Stock and (v) 20% of the Total Number of Directors, in the event that JFL collectively beneficially own 10% or more, but less
than 15%, of the shares of Common Stock (the “JFL Director” or “JFL Directors,” as the case
may be). For purposes of calculating the number of directors that JFLCo is entitled to designate pursuant to the immediately preceding
sentence, any fractional amounts shall automatically be rounded to the nearest whole number (e.g., one and three quarters (1-3/4)
directors shall equate to two (2) directors, one and one quarter (1-1/4) directors shall equate to one (1) director, or one and
one-half (1-1/2) directors shall equate to two (2) directors) and any such calculations shall be made after taking into account
any increase in the Total Number of Directors.

 

 

 

1
Note to Draft: Subject to Annex I of the Purchase Agreement.

 

    	 	- 2 -	 

    

    

 

(ii)  Subject
to the Federal Securities Laws and applicable national stock exchange requirements on which the Company’s Common Stock may
then be listed, at least one JFL Director shall be entitled to serve on each standing or ad hoc committee of the Board, and the
Board shall not create any new committees without the consent of at least one JFL Director.

 

(iii)  For
the avoidance of doubt, as of the Effective Date, each of Glenn M. Shor, C. Alexander Harman and James R. Baumgardner shall be
a JFL Director under the terms of this Agreement.

 

(b)  In
the event that the number of JFL Directors serving on the Board is less than the total number of JFL Directors that JFLCo shall
be entitled to nominate pursuant to Section 2(a)(i), then JFLCo shall have the right, at any time, to nominate such additional
nominee(s) to which JFLCo is entitled, in which case, the Board shall take all necessary corporate action (including as required
by Section 2(c) below) to (i) increase the size of the Board as required to enable JFLCo to so nominate such additional
nominee(s) and (ii) designate such additional nominee(s) to fill such newly created vacancies.

 

(c)  So
long as this Agreement remains in effect, in addition to any requirement of the Company’s Certificate of Incorporation,
Bylaws or the DGCL, the size of the Board shall not be increased without affirmative vote of at least one JFL Director.

 

(d)  The
following procedures shall be followed with respect to the nomination of JFL Directors pursuant to Section 2(a) and
any vacancy created by the death, resignation, retirement, disqualification or removal of any JFL Director:

 

(i)  For
purposes of whether JFLCo has a right to nominate a JFL Director pursuant to Section 2(a)(i), JFL’s beneficial ownership
of the outstanding Common Stock will be measured as of the record date for such meeting or written consent.

 

    	 	- 3 -	 

    

    

 

(ii)  Vacancies
arising through the death, resignation retirement, disqualification or removal of any JFL Director may be filled by the Board
only with a director nominee selected by JFLCo, and the JFL Director so chosen shall hold office until the next election and until
his or her successor is duly elected and qualified, or until his or her earlier death, resignation, retirement, disqualification
or removal.

 

(iii)  So
long as JFLCo is entitled to nominate any directors pursuant to Section 2(a)(i) hereof, the Company shall notify JFL Seller in
writing of the date on which proxy materials are expected to be mailed by the Company in connection with an election of directors
at an annual or special meeting of the shareholders (and the Company shall deliver such notice at least 60 days (or such shorter
period to which JFL Seller consents in writing) prior to such expected mailing date or such earlier date as may be specified by
the Company reasonably in advance of such earlier delivery date on the basis that such earlier delivery is necessary so as to
ensure that such nominee may be included in such proxy materials at the time such proxy materials are mailed). The Company shall
provide JFL Seller with a reasonable opportunity to review and provide comments on any portion of the proxy materials relating
to the JFL Director or the rights and obligations provided under this Agreement and to discuss any such comments with the Company.
The Company shall notify JFL Seller of any opposition to a JFL Director sufficiently in advance of the date on which such proxy
materials are to be mailed by the Company in connection with such election of directors so as to enable JFL Seller to propose
a replacement JFL Director, if necessary, in accordance with the terms of this Agreement, and JFL Seller shall have 10 business
days to designate another nominee.

 

(iv)  No
later than the latest date specified in or permitted by the Company’s Bylaws for stockholder director nominations for that
year’s annual meeting of stockholders, JFL Seller shall provide the Board with JFL Seller’s nominee(s), as the case
may be, for JFL Director(s), along with any other information reasonably requested by the Board to evaluate the suitability of
such candidate(s) for directorship; provided, that in no event shall JFL Seller be required to provide any such notice
of its nominees with respect to any JFL Director that is then currently serving on the Board and that has not provided notice
in writing to the Company of his or her decision not to stand for re-election at that year’s annual meeting; provided,
further, in no event will the failure to so timely nominate any JFL Director in accordance with the terms of this Section
2(d)(iv) or the Company’s Bylaws impair, restrict or limit the rights of JFL under this Agreement or the Company’s
obligation to nominate such directors at any meeting of stockholders or written consent related to the election of directors.
With respect to any JFLCo nominee, JFLCo shall use its reasonable best efforts to ensure that any such nominee substantially satisfies
all reasonable stated criteria and guidelines for director nominees of the Company (it being understood and agreed that each of
the JFL Directors on the Effective Date meet such criteria) and in compliance with applicable Federal Securities Laws and applicable
national stock exchange requirements on which the Company’s Common Stock may then be listed. The Company shall be entitled
to rely on any written direction from JFLCo regarding nominee(s) on behalf of JFL pursuant to this Agreement without further action
by the Company.

 

    	 	- 4 -	 

    

    

 

(v)  The
Board (or any authorized committee thereof) shall use all commercially reasonable efforts to the fullest extent of the DGCL and
other applicable law to nominate and include in the slate of nominees recommended by the Board for election at any meeting of
stockholders called for the purpose of electing directors the persons designated pursuant to this Section 2 and to nominate
and recommend each such individual to be elected as a JFL Director as provided herein, and to solicit proxies or consents in favor
thereof.

 

(e)  Notwithstanding
anything to the contrary in this Agreement and without any further action by the Company, JFL Seller’s right to nominate
any person to the Board shall automatically terminate, and be of no further force and effect, on the date that JFL collectively
beneficially own less than 10% of the Common Stock; provided that a reduction in the percentage of total voting power of
the Common Stock beneficially owned by JFL shall not shorten the term of any incumbent director. Notwithstanding the foregoing,
the Board may nominate an individual who previously served as JFL Director or any other Person associated or affiliated with JFL
for election or re-election to the Board at any time.

 

(f)  Each
of the JFL Directors, upon appointment or election to the Board, will be governed by the same protections and obligations as all
other directors of the Company, including, without limitation, protections and obligations regarding customary liability insurance
for directors and officers, confidentiality, conflicts of interests, fiduciary duties, trading and disclosure policies, director
evaluation process, director code of ethics, director share ownership guidelines, stock trading and pre-approval policies, and
other governance matters. The Company agrees that it shall enter into an indemnification agreement with each JFL Director as of
the Effective Date in the same form as indemnification agreements entered into with each of the other members of the Board, and
shall enter into substantially similar indemnification agreements whenever a new JFL Director becomes a member of the Board. The
Company shall at all times maintain paid and in effect directors and officers liability insurance policy coverage on terms commercially
reasonable and consistent with other similarly situated public companies which expressly cover all JFL Directors.

 

(g)  So
long as this Agreement shall remain in effect, subject to applicable legal requirements, the Bylaws and the Certificate of Incorporation
shall accommodate and be subject to and not in any respect conflict with the rights and obligations set forth herein.

 

3.  Miscellaneous.

 

(a)  Successors

hereto (whether by operation of law or otherwise) shall be void, invalid and of no effect without the prior written consent of

to one or more member(s) of JFL so long as the assignee(s) agree in writing to be bound by the terms and conditions of this Agreement.
The terms and conditions of this Agreement inure to the benefit of and are binding upon the respective successors and permitted
assignees of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties

of this Agreement, except as expressly provided herein.

 

    	 	- 5 -	 

    

    

 

(b)  Termination.

no longer has the authority to nominate a director to the Board of the Company pursuant to Section 2. Upon such termination,
no party shall have any further obligations or liabilities hereunder; provided that such termination shall not relieve
any party from liability for any breach of this Agreement prior to such termination.
