and agreements of the undersigned contained in this letter agreement in consummating the Transaction.

 

Annex A sets forth

definitions are a part of this letter agreement.

 

In consideration of
the foregoing, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the
undersigned hereby agrees that, during the applicable Lock-up Period, the undersigned will not (and will cause any Family Member
not to), without the prior written consent of the Company, which may withhold its consent in its sole discretion:

 

		·	Sell or Offer to Sell any of the Merger Shares,

 

		·	enter into any Swap,

 

		·	make any demand for, or exercise any right with respect to, the registration under the Securities

		·	publicly announce any intention to do any of the foregoing.

 

The foregoing restrictions

the avoidance of doubt, a fund managed by the same manager or managing member or general partner or management company or by an
entity controlling, controlled by, or under common control with such manager or managing member or general partner or management
company as the undersigned or who shares a common investment advisor with the undersigned), and (v) transfers
of Merger Shares pursuant to a bona fide third party tender offer, merger, consolidation or other similar transaction made to
all holders of Merger Shares involving a Change of Control of the Company, provided that in the event that the tender offer,
merger, consolidation or other such transaction is not completed, the Merger Shares owned by the undersigned shall remain subject
to the restrictions contained in this letter agreement; provided, however, that in any such case (except (v)), it shall
be a condition to such transfer that:

 

    

     

    

 

		·	each transferee executes and delivers to the Company an agreement in form and substance satisfactory
to the Company stating that such transferee is receiving and holding such Merger Shares subject to the provisions of this letter
agreement and agrees not to Sell or Offer to Sell such Merger Shares, engage in any Swap or engage in any other activities restricted
under this letter agreement except in accordance with this letter agreement (as if such transferee had been an original signatory
hereto),

 

		·	prior to the expiration of the applicable Lock-up Period, no public disclosure or filing under
the Exchange Act by any party to the transfer (donor, donee, transferor or transferee) shall be required, or made voluntarily,
reporting a reduction in beneficial ownership of Merger Shares in connection with such transfer, and

 

		·	any such transfers shall not involve a disposition for value.

 

“Change
of Control” shall mean the transfer (whether by tender offer, merger, consolidation or other similar transaction), in
one transaction or a series of related transactions, to a person or group of affiliated persons (other than a placement agent pursuant
to the Transaction), of the Company’s voting securities if, after such transfer, such person or group of affiliated persons
would hold more than 50% of the outstanding voting securities of the Company (or the surviving entity).

 

Despite anything to the contrary set forth
herein, none of the provisions of this letter agreement will apply to any Shares or Related Securities owned either of record or
beneficially (as defined in Rule 13d-3 under the Exchange Act), whether acquired prior to or after the date of this letter agreement,
by the undersigned (other than the Merger Shares).

 

The undersigned also agrees and consents
to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of Merger
Shares held by the undersigned and the undersigned’s Family Members, if any, except in compliance with the foregoing restrictions.

 

The undersigned confirms that the undersigned
has not, and has no knowledge that any Family Member has, directly or indirectly, taken any action designed to or that might reasonably
be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the
sale of the Merger Shares. The undersigned will not, and will cause any Family Member not to take, directly or indirectly, any
such action.

 

The undersigned hereby represents and warrants
that the undersigned has full power, capacity and authority to enter into this letter agreement. This letter agreement is irrevocable
and will be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned.

 

This letter agreement shall be governed

NOW, THEREFORE,
in consideration of the premises herein contained, and for other good and valuable consideration (the receipt, sufficiency and
adequacy of which are hereby acknowledged), the parties hereto (intending to be legally bound) hereby agree as follows:

 

1.       Incorporation.
The foregoing preamble and recitals are incorporated herein by this reference.

 

    

     

    

 

2.       Joinder
and Assumption. From and after the Effective Date, New Borrower hereby absolutely and unconditionally:

 

(a) (i) joins as and
becomes a party to the Loan Agreement as a Borrower thereunder, (ii) assumes, as a joint and several obligor thereunder, all of
the obligations, liabilities and indemnities of a Borrower under the Loan Agreement and all other Loan Documents, and (iii) covenants
and agrees to be bound by and adhere to all of the terms, covenants, waivers, releases, agreements and conditions of or respecting
a Borrower with respect to the Loan Agreement and the other Loan Documents and all of the representations and warranties contained
in the Loan Agreement (in the manner set forth in Section 5 of this Joinder) and the other Loan Documents with respect to New Borrower;
and

 

(b)       hereby
grants and pledges to the Bank, a continuing security interest in all of such New Borrower’s now owned and existing and hereafter
acquired and arising Collateral, as collateral security for the prompt and complete payment and performance when due (whether at
the stated maturity, by acceleration or otherwise) of all Obligations. New Borrower hereby authorizes the Bank to file at any time
uniform commercial code financing statements in such jurisdictions and offices as the Bank deems necessary in connection with the
perfection of a security interest in all of such New Borrower’s now owned or hereafter arising or acquired assets and property,
including, without limitation, accounts receivable, deposit accounts, equipment, general intangibles, inventory, and any and all
other personal property of such New Borrower, and all products, substitutions, replacements, and proceeds of such property and
assets. New Borrower has read the Loan Agreement and affirmatively grants to Bank all rights to New Borrower’s assets as
set forth in said Loan Agreement and the Loan Documents.

 

From and after the
Effective Date, any reference to the term “Borrower” in the Loan Agreement shall also include New Borrower. Except
as expressly provided herein, the Loan Agreement remains in full force and effect and is hereby ratified and confirmed in all respects.

 

3.      Amendments
on the Effective Date. Effective as of the Effective Date, the Loan Agreement is hereby amended as follows:

 

(a) A new Section 4.3
is hereby added to the Loan Agreement, as follows:

 

4.3       Pledge
of Collateral. Borrower hereby pledges, assigns and grants to Bank a security interest in all the Shares, together with
all proceeds and substitutions thereof, all cash, stock and other moneys and property paid thereon, all rights to subscribe
for securities declared or granted in connection therewith, and all other cash and noncash proceeds of the foregoing, as
security for the performance of the Obligations. Borrower will deliver to Bank (i) on the Closing Date, the certificate or
certificates for any then-certificated Shares, and (ii) with respect to any Shares uncertificated as of the Closing Date,
immediately upon certification, the certificate or certificates for the Shares, in each case accompanied by an instrument of
assignment duly governing the Shares. Borrower shall cause the books of each entity whose Shares are part of the Collateral
and any transfer agent to reflect the pledge of the Shares. Upon the occurrence and during the continuance of an Event of
Default hereunder, Bank may effect the transfer of any securities included in the Collateral (including but not limited to
the Shares) into the name of Bank and cause new certificates representing such securities to be issued in the name of Bank or
its transferee. Unless an Event of Default shall have occurred and be continuing, Borrower shall be entitled to exercise any
voting rights with respect to the Shares and to give consents, waivers and ratifications in respect thereof, provided that no
vote shall be cast or consent, waiver or ratification given or action taken which would be inconsistent with any of the terms
of this Agreement or which would constitute or create any violation of any of such terms. All such rights to vote and give
consents, waivers and ratifications shall terminate upon the occurrence and continuance of an Event of Default.

 

    2

     

    

 

(b) A new Section
5.14 is hereby added to the Loan Agreement, as follows:

 

5.14     Shares.
Borrower has full power and authority to create a first lien on the Shares, and no disability or contractual obligation exists
that would prohibit Borrower from pledging the Shares pursuant to this Agreement. To Borrower’s knowledge, there are no subscriptions,
warrants, rights of first refusal or other restrictions on transfer relative to, or options exercisable with respect to the Shares.
The Shares have been and will remain duly authorized and validly issued, and are fully paid and non-assessable. To Borrower’s
knowledge, the Shares are not the subject of any present or threatened suit, action, arbitration, administrative or other proceeding,
and Borrower knows of no reasonable grounds for the institution of any such proceedings. No interest in any limited liability company
or limited partnership controlled by Borrower is represented by a certificate unless (a) the limited liability company agreement
or limited partnership agreement expressly provides that such interest shall be a “Security” within the meaning of
Article 8 of the Code, and (b) such certificate has been delivered to Bank. With respect to each limited liability company or limited
partnership controlled by Borrower whose interests are uncertificated, such limited liability company or limited partnership has
not elected, whether in its limited liability company agreement or limited partnership agreement or otherwise, to have such interests
be treated as a “Security” within the meaning of Article 8 of the Code.

 

(c) A new Article
13 is hereby added to the Loan Agreement, as follows:

 

13.      
 CO-BORROWER PROVISIONS.

 

13.1     Primary
Obligation. This Agreement is a primary and original obligation of each Borrower and shall remain in effect notwithstanding
future changes in conditions, including any change of law or any invalidity or irregularity in the creation or acquisition of any
Obligations or in the execution or delivery of any agreement between Bank and any Borrower. Each Borrower shall be liable for existing
and future Obligations as fully as if all of all Credit Extensions were advanced to such Borrower. Bank may rely on any certificate
or representation made by any Borrower as made on behalf of, and binding on, all Borrowers, including without limitation Disbursement
Request Forms, Borrowing Base Certificates and Compliance Certificates.

 

13.2     Enforcement
of Rights. Borrowers are jointly and severally liable for the Obligations and Bank may proceed against one or more of the Borrowers
to enforce the Obligations without waiving its right to proceed against any of the other Borrowers.

 

13.3     Borrowers
as Agents. Each Borrower appoints the other Borrower as its agent with all necessary power and authority to give and receive
notices, certificates or demands for and on behalf of both Borrowers, to act as disbursing agent for receipt of any Credit Extensions
on behalf of each Borrower and to apply to Bank on behalf of each Borrower for Credit Extensions, any waivers and any consents.
This authorization cannot be revoked, and Bank need not inquire as to each Borrower’s authority to act for or on behalf of
Borrower.

 

    3

     

    

 

13.4    Subrogation and Similar Rights. Notwithstanding any other provision of this Agreement or any other Loan Document, each
Borrower irrevocably waives all rights that it may have at law or in equity (including, without limitation, any law subrogating
the Borrower to the rights of Bank under the Loan Documents) to seek contribution, indemnification, or any other form of reimbursement
from any other Borrower, or any other Person now or hereafter primarily or secondarily liable for any of the Obligations, for any
payment made by the Borrower with respect to the Obligations in connection with the Loan Documents or otherwise and all rights
that it might have to benefit from, or to participate in, any security for the Obligations as a result of any payment made by the
Borrower with respect to the Obligations in connection with the Loan Documents or otherwise. Any agreement providing for indemnification,
reimbursement or any other arrangement prohibited under this Section 13.4 shall be null and void. If any payment is made to a Borrower
in contravention of this Section 13.4, such Borrower shall hold such payment in trust for Bank and such payment shall be promptly
delivered to Bank for application to the Obligations, whether matured or unmatured.

 

13.5   
Waivers of Notice. Except as otherwise provided in this Agreement, each Borrower waives notice of acceptance hereof;
notice of the existence, creation or acquisition of any of the Obligations; notice of an Event of Default; notice of the amount
of the Obligations outstanding at any time; notice of intent to accelerate; notice of acceleration; notice of any adverse change
in the financial condition of any other Borrower or of any other fact that might increase the Borrower’s risk; presentment
for payment; demand; protest and notice thereof as to any instrument; default; and all other notices and demands to which the Borrower
would otherwise be entitled. Each Borrower waives any defense arising from any defense of any other Borrower, or by reason of the
cessation from any cause whatsoever of the liability of any other Borrower. Bank’s failure at any time to require strict
performance by any Borrower of any provision of the Loan Documents shall not waive, alter or diminish any right of Bank thereafter
to demand strict compliance and performance therewith. Nothing contained herein shall prevent Bank from foreclosing on the Lien
of any deed of trust, mortgage or other security instrument, or exercising any rights available thereunder, and the exercise of
any such rights shall not constitute a legal or equitable discharge of any Borrower. Each Borrower also waives any defense arising
from any act or omission of Bank that changes the scope of the Borrower’s risks hereunder.

 

13.6   
Subrogation Defenses. Each Borrower hereby waives any defense based on impairment or destruction of its subrogation
or other rights against any other Borrower and waives all benefits which might otherwise be available to it under any statutory
or common law suretyship defenses or marshalling rights, now or hereafter in effect.

 

13.7    
Right to Settle, Release.

 

(a)       
The liability of Borrowers hereunder shall not be diminished by (i) any agreement, understanding or representation that
any of the Obligations is or was to be guaranteed by another Person or secured by other property, or (ii) any release or unenforceability,
whether partial or total, of rights, if any, which Bank may now or hereafter have against any other Person, including another Borrower,
or property with respect to any of the Obligations.

 

    4

     

    

 

(b)      
 Without affecting the liability of any Borrower hereunder, Bank may (i) compromise, settle, renew, extend the time
for payment, change the manner or terms of payment, discharge the performance of, decline to enforce, or release all or any of
the Obligations with respect to a Borrower, (ii) grant other indulgences to a Borrower in respect of the Obligations, (iii) modify
in any manner any documents relating to the Obligations with respect to a Borrower, (iv) release, surrender or exchange any deposits
or other property securing the Obligations, whether pledged by a Borrower or any other Person, or (v) compromise, settle, renew,
or extend the time for payment, discharge the performance of, decline to enforce, or release all or any obligations of any guarantor,
endorser or other Person who is now or may hereafter be liable with respect to any of the Obligations.

 

13.8    
Subordination. All indebtedness of a Borrower now or hereafter arising held by another Borrower is subordinated to the
Obligations and the Borrower holding the indebtedness shall take all actions reasonably requested by Bank to effect, to enforce
and to give notice of such subordination.

any time, Borrower shall cease to own and control, of record and beneficially, directly or indirectly, one hundred percent (100%)
