(2)         Upon
the termination of the Commitment for any reason whatsoever, or upon the occurrence of a Default, the Bank may, at its option,
demand that the Borrower, within ten (10) days of such demand, arrange for the cancellation of any or all of the Letters of Credit
such that the Bank has no further liability under said Letters of Credit, or in the event the Borrower fails to procure the cancellation
of either Letter of Credit within such ten (10) day period, demand that the Borrower pay to the Bank, as cash collateral, the remaining
amount available to be drawn, if any, under said Letter of Credit and such amount shall thereupon become immediately due and payable.
In the event the Borrower pays to the Bank or the Bank collects from the Borrower sums representing the remaining amount available
to be drawn under said Letter of Credit, the Bank shall hold such sums in a non-interest-bearing account as security for the Borrower’s
obligation to reimburse the Bank for amounts paid by the Bank under said Letter of Credit or otherwise due hereunder. Upon the
expiration of said Letter of Credit and the Bank's reasonable determination that it has no further liability thereunder, the Bank
shall repay such sums to the Borrower to the extent they exceed the remaining amounts actually paid by the Bank under said Letter
of Credit. The Bank's rights under this Section II(F) are in addition to other rights and remedies which the Bank may have.

 

(G)         The
Term Loan. The Bank agrees, on the terms and conditions set forth in this Agreement and the Term Note, to make a term loan
(the “Term Loan”) to the Borrower on the Effective Date in the principal amount of $5,000,000.00. The Term Loan shall
be evidenced by, and repayable with interest in accordance with, the Term Note.

 

III.         THE
SECURITY INTERESTS.

 

(A)         Grant
of Security Interests. To secure the due and punctual payment of all Obligations, howsoever created, arising or evidenced,
whether direct or indirect, absolute or contingent, now or hereafter existing or due or to become due, in accordance with the terms
thereof and to secure the due and punctual performance of all of the obligations of the Borrower contained in the Notes and this
Agreement and in the other Loan Documents to which it is a party and in order to induce the Bank to enter into this Agreement and
make the Advances and the Term Loan provided for therein and herein in accordance with the terms hereof and thereof, the Borrower
hereby grants to the Bank a security interest in all of the Borrower's right, title and interest in, to and under the following,
whether now existing or hereafter acquired (all of which are herein collectively called the "Collateral"):

 

    	-11-

    	 

    

  

(1)         all
Receivables;

 

(2)         all
Other Intangibles;

 

(3)         all
Equipment;

 

(4)         all
Inventory;

 

(5)         to
the extent not included in the foregoing, all other personal property, whether tangible or intangible, and wherever located, including,
but not limited to, the balance of every deposit account now or hereafter existing of the Borrower with any bank and all monies
of the Borrower and all rights to payment of money of the Borrower;

 

(6)         to
the extent not included in the foregoing, all books, ledgers and records and all computer programs, tapes, discs, punch cards,
data processing software, transaction files, master files and related property and rights (including computer and peripheral equipment)
necessary or helpful in enforcing, identifying or establishing any item of Collateral; and

 

(7)         to
the extent not otherwise included, all Proceeds and products of any or all of the foregoing, whether existing on the date hereof
or arising hereafter.

 

Notwithstanding any provision herein to the contrary, the Bank
shall not have a security interest in any of the above property to the extent the granting of a security interest therein violates
any provision of applicable law or any contract with an Account Debtor giving rise to a Receivable.

 

(B)         Continuing
Liability of the Borrower. Anything herein to the contrary notwithstanding, the Borrower shall remain liable to observe and
perform all the terms and conditions to be observed and performed by it under any contract, agreement, warranty or other obligation
with respect to the Collateral, and shall do nothing to impair the security interests herein granted. The Bank shall not have any
obligation or liability under any such contract, agreement, warranty or obligation by reason of or arising out of this Agreement
or the receipt by the Bank of any payment relating to any Collateral, nor shall the Bank be required to perform or fulfill any
of the obligations of the Borrower with respect to the Collateral, to make any inquiry as to the nature or sufficiency of any payment
received by it or the sufficiency of the performance of any party's obligations with respect to any Collateral. Furthermore, the
Bank shall not be required to file any claim or demand to collect any amount due or to enforce the performance of any party's obligations
with respect to, the Collateral.

 

(C)         Sales
and Collections.

 

(1)         The
Borrower is authorized (a) to sell in the ordinary course of its business for fair value and on an arm's-length basis any of its
Inventory normally held by it for such purpose and (b) to use and consume, in the ordinary course of its business, any raw materials,
supplies and materials normally held by it for such purpose. The Bank may upon the occurrence of any Default Condition, without
cause or notice, curtail or terminate such authority at any time.

 

    	-12-

    	 

    

 

(2)         Upon
the request of the Bank, in the Bank’s sole discretion, all Account Debtors shall be notified to make payments under Receivables
directly to the Bank, in accordance with the Bank’s standard lockbox agreement. The Borrower will use all reasonable efforts
to cause each Account Debtor to comply with the foregoing instruction. In furtherance of the foregoing, the Borrower authorizes
the Bank (a) to ask for, demand, collect, receive and give acquittances and receipts for any and all amounts due and to become
due under any Collateral and, in the name of the Borrower or its own name or otherwise, (b) to take possession of, indorse and
collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due under any Collateral and (c)
to file any claim or take any other action in any court of law or equity or otherwise which it may deem appropriate for the purpose
of collecting any amounts due under any Collateral. The Bank shall have no obligation to obtain or record any information relating
to the source of such funds or the obligations in respect of which payments have been made.

 

(D)         Segregation
of Proceeds.

 

(1)         The
Bank shall have the right at any time (regardless of whether or not a Default shall have occurred) to cause to be opened and maintained
at the principal office of the Bank a non-interest bearing bank account (the "Cash Collateral Account") which will contain
only Proceeds. Any cash proceeds (as such term is defined in Section 8.9A-102(a)(9) of the UCC) received by the Bank from the Borrower
pursuant to paragraph (2) of this subsection (D), whether consisting of checks, notes, drafts, bills of exchange, money orders,
commercial paper or other Proceeds received on account of any Collateral, shall be promptly deposited in the Cash Collateral Account,
and until so deposited shall be held in trust for and as the Bank's property and shall not be commingled with any funds of the
Borrower not constituting Proceeds of Collateral. The name in which the Cash Collateral Account is carried shall clearly indicate
that the funds deposited therein are the property of the Borrower, subject to the security interest of the Bank hereunder. Such
Proceeds, when deposited, shall continue to be security for the Obligations and shall not constitute payment thereof until applied
as hereinafter provided. The Bank shall have sole dominion and control over the funds deposited in the Cash Collateral Account,
and such funds may be withdrawn therefrom only by the Bank; provided, however, that until a Default shall occur,
all collected funds on deposit in the Cash Collateral Account, or so much thereof as is not required to make payment of the Obligations
which have become due and payable, shall be withdrawn by the Bank on the Business Day next following the day on which the Bank
considers the funds deposited therein to be collected funds and disbursed to the Borrower or its order.

 

(2)         Upon
notice by the Bank to the Borrower that the Cash Collateral Account has been opened, the Borrower shall cause all cash Proceeds
collected by it pursuant to paragraph (1), above, to be delivered to the Bank forthwith upon receipt, in the original form in which
received (with such indorsements or assignments as may be necessary to permit collection thereof by the Bank), and for such purpose
the Borrower hereby irrevocably authorizes and empowers the Bank, its officers, employees and authorized agents to indorse and
sign the name of the Borrower on all checks, drafts, money orders or other media of payment so delivered, and such indorsements
or assignments shall, for all purposes, be deemed to have been made by the Borrower prior to any indorsement or assignment thereof
by the Bank. The Bank may use any convenient or customary means for the purpose of collecting such checks, drafts, money orders
or other media of payment.

 

    	-13-

    	 

    

 

(E)         Verification
of Receivables. The Bank shall have the right to make test verifications of Receivables in any manner and through any medium
that it considers advisable, and the Borrower agrees to furnish all such assistance and information as the Bank may require in
connection therewith. The Borrower at its expense will cause either independent certified public accountants or, if agreeable to
the Bank in its sole discretion, the Borrower's chief financial officer, to furnish to the Bank at any time and from time to time
promptly upon the Bank's request, the following reports: (i) a reconciliation of all Receivables, (ii) an aging of all Receivables,
(iii) trial balances and (iv) a test verification of such Receivables as the Bank may request.

 

(F)         Release of Collateral.

 

(1)         The
Borrower may sell or realize upon or transfer or otherwise dispose of Collateral as permitted by Section VI(B)(13), and the security
interests of the Bank in such Collateral so sold, realized upon or disposed of (but not in the Proceeds arising from such sale,
realization or disposition) shall cease immediately upon such sale, realization or disposition, without any further action on the
part of the Bank. The Bank, if requested in writing by the Borrower but at the expense of the Borrower, is hereby authorized and
instructed to deliver to the Account Debtor or the purchaser or other transferee of any such Collateral a certificate stating that
the Bank no longer has a security interest therein, and such Account Debtor or such purchaser or other transferee shall be entitled
to rely conclusively on such certificate for any and all purposes.

 

(2)         Upon
the payment in full of all of the Obligations and if there is no commitment by the Bank to make further Advances, incur obligations
or otherwise give value, the Bank will (as soon as reasonably practicable after receipt of notice from the Borrower requesting
the same but at the expense of the Borrower) send the Borrower, for each jurisdiction in which a UCC financing statement is on
file to perfect the security interests granted to the Bank hereunder, a termination statement to the effect that the Bank no longer
claims a security interest under such financing statement.

of covenant under this Agreement.

 

V.          REPRESENTATIONS AND WARRANTIES.

 

The Borrower represents and warrants that:

 

(A)         Existence
and Power.

 

(1)         Each
corporate Borrower is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of
its incorporation, and no other jurisdiction. The name of the Borrower, as set forth on the signature pages of this Agreement,
is as said name appears in the public records of said jurisdiction. The Borrower has all corporate powers and all material governmental
licenses, authorizations, consents and approvals required to carry on its business as now conducted. The Borrower is duly qualified
as a foreign entity, licensed and in good standing in each jurisdiction where qualification or licensing is required by the nature
of its business or the character and location of its property, business or customers and in which the failure to so qualify or
be licensed, as the case may be, in the aggregate, could have a material adverse effect on the business, financial position, results
of operations, properties or prospects of the Borrower.

 

    	-16-

    	 

    

 

(2)         Each
limited liability company Borrower is a limited liability company duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization, and no other jurisdiction. The name of the Borrower, as set forth on the signature
pages of this Agreement, is as said name appears in the public records of said jurisdiction. The Borrower has all organizational
powers and all material governmental licenses, authorizations, consents and approvals required to carry on its business as now
conducted. The Borrower is duly qualified as a foreign entity, licensed and in good standing in each jurisdiction where qualification
or licensing is required by the nature of its business or the character and location of its property, business or customers and
in which the failure to so qualify or be licensed, as the case may be, in the aggregate, could have a material adverse effect on
the business, financial position, results of operations, properties or prospects of the Borrower.

 

(B)         Organizational
and Governmental Authorization; Contravention. The execution, delivery and performance by the Borrower of this Agreement, the
Notes and the other Loan Documents to which it is a party are within its organizational power, have been duly authorized by all
necessary corporate action, or action of its members, as the case may be, require no action by or in respect of, or filing with,
any governmental body, agency or official and do not contravene, or constitute (with or without the giving of notice or lapse of
time or both) a default under, any provision of applicable law or of the organizational documents of the Borrower or of any agreement,
judgment, injunction, order, decree or other instrument binding upon or affecting the Borrower or result in the creation or imposition
of any Lien (other than the Lien of this Agreement and the other Loan Documents) on any of its assets.

 

(C)         Binding
Effect. This Agreement constitutes a valid and binding agreement of the Borrower and the Notes and Applications, when executed
and delivered in accordance with this Agreement, will constitute valid and binding obligation of the Borrower, in each case enforceable
against the Borrower in accordance with its terms, except as (1) the enforceability hereof and thereof may be limited by bankruptcy,
insolvency or similar laws affecting creditors' rights generally and (2) rights of acceleration and the availability of equitable
remedies may be limited by equitable principles of general applicability.

 

(D)         Title
to Collateral. Except for the security interests granted to the Bank pursuant to this Agreement, the Borrower is the sole owner
of each item of the Collateral, having good and marketable title thereto, free and clear of any and all Liens, except Permitted
Liens.

 

(E)         Validity,
Perfection and Priority of Security Interests.

 

(1)         By
complying with Section VI(B)(1), the Borrower will have created a valid security interest in favor of the Bank in all existing
Collateral and in all identifiable Proceeds of such Collateral, which security interest (except in respect of motor vehicles for
which the exclusive manner of perfecting a security interest therein is by noting such security interest on the certificate of
title in accordance with local law) would be prior to the claims of a trustee in bankruptcy under Section 544(a) of the federal
Bankruptcy Code. Continuing compliance by the Borrower with the provisions of Section VI(B)(2) will also (a) create valid security
interests in all Collateral acquired after the date hereof and in all identifiable Proceeds of such Collateral and (b) cause such
security interests in all Collateral and in all Proceeds which are (i) identifiable cash Proceeds of Collateral covered by financing
statements required to be filed hereunder, (ii) identifiable Proceeds in which a security interest may be perfected by such filing
under the UCC and (iii) any Proceeds in the Cash Collateral Account to be duly perfected under the UCC, in each case prior to the
claims of a trustee in bankruptcy under the federal Bankruptcy Code.

 

    	-17-

    	 

    

 

(2)         The
security interests of the Bank in the Collateral rank first in priority. Other than financing statements or other similar documents
perfecting the security interests of the Bank, no financing statements or similar documents covering all or any part of the Collateral
are on file or of record in any government office in any jurisdiction in which such filing or recording would be effective to perfect
a security interest in such Collateral, nor is any of the Collateral in the possession of any person (other than the Borrower)
asserting any claim thereto or security interest therein.

 

(F)         Enforceability
of Receivables and Other Intangibles. To the best knowledge of the Borrower, each Receivable and Other Intangible is a valid
and binding obligation of the related Account Debtor in respect thereof, enforceable in accordance with its terms, except as such
enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement
of creditors' rights generally and by general provisions of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law), and complies with any applicable legal requirements.

 

(G)         Places
of Business; Location of Collateral. Appendix 1 hereto correctly sets forth each Borrower’s current chief executive office,
any and all chief executive offices of said Borrower within the previous four (4) months, all other places of business of said
Borrower and the offices of said Borrower where records concerning Receivables and Other Intangibles are kept. Appendix 2 hereto
correctly sets forth the location of all Equipment and Inventory, other than rolling stock, aircraft, goods in transit and Inventory
sold in the ordinary course of business as permitted by Section VI(B)(13) of this Agreement. Except as otherwise specified in Appendix
2 hereto , all Inventory and Equipment has been located at the address specified on said Appendix 2 at all times during the four-month
period prior to the date hereof while owned by said Borrower. All Inventory has been and will be produced in compliance with the
Fair Labor Standards Act, 29 U.S.C. §§ 201-219. No Inventory is evidenced by a negotiable document of title, warehouse
receipt or bill of lading. No non-negotiable document of title, warehouse receipt or bill of lading has been issued to any person
other than said Borrower, and said Borrower has retained possession of all of such non-negotiable documents, warehouse receipts
and bills of lading. No amount payable under or in connection with any of the Collateral is evidenced by promissory notes or other
instruments.

 

(H)         Trade
Names. Any and all trade names, division names, assumed names or other names under which each Borrower transacts, or within
the four-month period prior to the date hereof has transacted, business are specified on Appendix 3 hereto.

 

(I)           Financial Information.

 

(1)         The
most recent fiscal year end consolidated balance sheet of Versar and the related consolidated financial statements, reported on
by Versar's independent public accountants, copies of which have been delivered to the Bank, fairly present, in conformity with
GAAP, the financial position of Versar and its Consolidated Subsidiaries as of the date thereof and its results of operations and
cash flows for such fiscal year. As of the date of such financial statements, no Borrower has had any material contingent obligation,
contingent liability or liability for Taxes, long-term lease or unusual forward or long-term commitment, which is not reflected
in any of such financial statements or notes thereto.

 

    	-18-

    	 

    

 

(2)         Since
the date of the most recent balance sheet, there has been no material adverse change in the business, financial position, results
of operations or prospects of the Borrower.

 

(J)         Litigation.
There is no action, suit or proceeding pending against, or to the knowledge of the Borrower threatened against or affecting, the
Borrower before any Government in which there is a reasonable possibility of an adverse decision which could materially adversely
affect the business, financial position or results of operations of the Borrower or which in any manner draws into question the
validity of this Agreement, the Notes, or any other Loan Document and there is no basis known to the Borrower for any such action,
suit or proceeding.

 

(K)         Marketable
Title. The Borrower has good and marketable title to all its properties and assets subject to no Lien, except Permitted Liens.

 

(L)         Filings.
All actions by or in respect of, and all filings with, any governmental body, agency or official required in connection with the
execution, delivery and performance of this Agreement, the Notes and the other Loan Documents, or necessary for the validity or
enforceability thereof or for the protection or perfection of the rights and interests of the Bank thereunder, will, prior to the
date of delivery thereof, have been duly taken or made, as the case may be, and will at all times thereafter remain in full force
and effect.

 

(M)         Regulation
U. The proceeds of the Advances and the Term Loan will be used by the Borrower only for the purposes set forth in Section VI(C)(14)
hereof. None of the proceeds of the Term Loan or any Advance will be used, directly or indirectly, for the purpose of purchasing
or carrying any "margin stock" or for the purpose of reducing or retiring any indebtedness which was originally incurred
to purchase or carry margin stock or for any other purpose which might constitute the loan evidenced by the Revolving Note, or
any Advance, a "purpose credit" within the meaning of Regulation U or Regulation X of the Board of Governors of the Federal
Reserve System. The proceeds of the Term Loan will be used for the purpose of purchasing and carrying the stock of Geo-Marine,
but said stock is not "margin stock", and the Term Loan is therefore not a "purpose credit" within the meaning
of said Regulation U.

 

(N)         Taxes.
The Borrower has filed all United States Federal income Tax returns and all other material Tax returns which are required to be
filed by it and has paid all Taxes due pursuant to such returns or pursuant to any assessment received by the Borrower. The charges,
accruals and reserves on the books of the Borrower in respect of Taxes or other governmental charges are adequate.

 

(O)         Suspension
or Debarment. Neither the Borrower nor any Subsidiary, nor any of their respective directors, officers or employees, has received
any notice of, or information concerning, any proposed, contemplated or initiated suspension or debarment, be it temporary or permanent,
due to an administrative or a statutory basis, of the Borrower or any Subsidiary by any Government. The Borrower further warrants
and represents that neither the Borrower nor any Subsidiary has defaulted under any Government Contract which default would be
a basis of terminating such Government Contract.

 

(P)         Anti-Terrorism
Laws.

  

(1)         General.
Neither the Borrower nor or any Affiliate of the Borrower is in violation of any Anti-Terrorism Law or engages in or conspires
to engage in any transaction that evades or avoids, or has the purpose of evading or avoiding, or attempts to violate, any of the
prohibitions set forth in any Anti-Terrorism Law.

 

    	-19-

    	 

    

  

(2)         Executive
Order No. 13224. Neither the Borrower, nor or any Affiliate of the Borrower, or their respective agents acting or benefiting
in any capacity in connection with the Term Loan, the Advances, or other transactions hereunder, is any of the following (each
a “Blocked Person”): (a) a Person that is listed in the annex to, or is otherwise subject to the provisions of, Executive
Order No. 13224, (b) a Person owned or controlled by, or acting for or on behalf of, any Person that is listed in the annex to,
or is otherwise subject to the provisions of, Executive Order No. 13224, (c) a Person or entity with which any Bank is prohibited
from dealing or otherwise engaging in any transaction by any Anti-Terrorism Law, (d) a Person or entity that commits, threatens
or conspires to commit or supports “terrorism” as defined in Executive Order No. 13224, (e) a Person or entity that
is named as a “specially designated national” on the most current list published by the U.S. Treasury Department Office
of Foreign Asset Control at its official website or any replacement website or other replacement official publication of such list,
or (f) a person or entity who is affiliated or associated with a person or entity listed above.

 

The Borrower, or to the knowledge of any
Borrower, any of its agents acting in any capacity in connection with the Advances or the Term Loan or other transactions hereunder,
does not (i) conduct any business or engage in making or receiving any contribution of funds, goods or services to or for the benefit
of any Blocked Person, or (ii) deal in, or otherwise engage in any transaction relating to, any property or interests in property
blocked pursuant to Executive Order No. 13224.

 

(Q)         Subsidiaries.
Versar has no Subsidiary that is not a Borrower. Versar Global Solutions, Inc., VEC Corp., and Advent Environmental, Inc., which
were “Borrowers” under the Original Loan Agreement and the Original Note, are not Material Subsidiaries and either
no longer exist or are in the process of being dissolved as of the Effective Date.

 

(R)         Disclosure.
None of this Agreement, any other Loan Document, any schedule or exhibit thereto or document, certificate, report, statement or
other information furnished to the Bank in connection herewith or therewith or in connection with the consummation of the transactions
contemplated hereby or thereby contains any material misstatement of fact or omits to state a material fact necessary to make the

    	-29-

    	 

    

 

Nothing in this paragraph (10) shall prohibit the Borrower from
making sales to or purchases from any Affiliate and, in connection therewith, extending credit or making payments, or from making
payments for services rendered by any Affiliate, if such sales or purchases are made or such services are rendered in the ordinary
course of business and on terms and conditions at least as favorable to the Borrower as the terms and conditions which would apply
in a similar transaction with a person not an Affiliate, or prohibit the Borrower from participating in, or effecting any transaction
in connection with, any joint enterprise or other joint arrangement with any Affiliate if the Borrower participates in the ordinary
course of its business and on a basis no less advantageous than on the basis on which such Affiliate participates.

 

(11)        Restricted
Payments. The Borrower will not (a) declare or pay any dividend or other distribution on any shares of the Borrower's capital
stock, (except dividends payable solely in shares of its capital stock), (b) make any payment that would cause the aggregate amount
of all such payments in any fiscal year to exceed $500,000.00, on account of the purchase, redemption, retirement or acquisition

capital stock) or (ii) any option, warrant or other right to acquire shares of the Borrower's capital stock.

 

(12)        Investments.

of, and suppliers to, the Borrower, in each case in the ordinary course of business.

 

(13)        Transactions
with Other Persons. The Borrower shall not enter into any agreement with any person whereby any of them shall agree to any
restriction on the Borrower's right to amend or waive any of the provisions of this Agreement.

legal matters incident to such Subsidiary’s becoming a Borrower shall be reasonably satisfactory to counsel for the Bank
and the Subsidiary shall execute and deliver to the Bank, within 30 days after its acquisition or formation, such additional documents
and certificates relating to the Loan as the Bank reasonably may request.

 

(iii)        The
Bank shall have received, within 30 days after said acquisition or formation, an opinion of counsel to such Subsidiary, addressed
to the Bank, covering such matters as the Bank may reasonably request, in form and substance reasonably satisfactory to the Bank.

 

(iv)        Financing
statements in form and substance reasonably satisfactory to the Bank shall have been properly filed in each office where necessary
to perfect the security interest of the Bank in the Collateral of such Subsidiary, and, within 30 days after said acquisition or
formation, (A) termination statements shall have been filed with respect to any other financing statements covering all or any
portion of such Collateral (except with respect to Liens permitted by this Agreement), (B) all Taxes and fees with respect to such

Subsidiary is to become a Borrower, by its secretary or representative performing similar functions; copies of evidence of all
actions taken by such Subsidiary to authorize the execution and delivery of the applicable Loan Documents;  copies of the
articles or certificate of incorporation and bylaws (or the organizational documents for a Borrower that is not a corporation)
of such Subsidiary; and  a certificate as to the incumbency and signatures of the officers of such Subsidiary executing the
Loan Documents.

 

    	-31-

    	 

    

 

(vi)        The
Bank shall have received current certificates of good standing and qualification issued by the appropriate state official of the
state of formation of such Subsidiary and in each jurisdiction in which it is qualified to do business.

 

(vii)       The
Bank shall have received, within 30 days after said acquisition or formation, such information and documents the Bank may reasonably
request with respect to the Collateral of such Subsidiary.

 

(viii)      If
required by the Bank, the Bank shall have received, within 30 days after said acquisition or formation, a satisfactory field examination

with Geomet Technologies, LLC, Charron Construction Consulting, Incorporated, Geo-Marine, Inc., and J.M. Waller Associates, Inc.

opinion of counsel to such Specified Subsidiary, addressed to the Bank, covering such matters as the Bank may reasonably request,
in form and substance reasonably satisfactory to the Bank.

 

(D)         Independence
of Covenants. All covenants contained in this Agreement shall be given independent effect so that if a particular action or
condition is not permitted by any of such covenants, the fact that such action or condition would be permitted by an exception
to, or otherwise be within the limitations of another covenant shall not avoid the occurrence of a Default Condition if such action
is taken or condition exists.

 

VII.         REMEDIES.

 

(A)         UCC
Rights. If any Default shall have occurred, the Bank may in addition to all other rights and remedies granted to it in this
Agreement, the Note, any and all other Loan Documents and in any other instrument or agreement securing, evidencing or relating
to the Obligations, exercise all rights and remedies of a secured party under the UCC and all other rights available to the Bank
at law or in equity.

 

(B)         Payments
on Collateral. Without limiting the rights of the Bank under any other provision of this Agreement, if a Default shall occur
and be continuing:

 

    	-32-

    	 

    

 

(1)         all
payments received by the Borrower under or in connection with any of the Collateral shall be held by the Borrower in trust for
the Bank, shall be segregated from other funds of the Borrower and shall forthwith upon receipt by the Borrower be turned over
to the Bank, in the same form as received by the Borrower (duly indorsed by the Borrower to the Bank, if required to permit collection
thereof by the Bank); and

 

(2)         all
such payments received by the Bank (whether from the Borrower or otherwise) may, in the sole discretion of the Bank, be held by
the Bank as collateral security for, and then or at any time thereafter applied in whole or in part by the Bank to the payment
of the expenses and Obligations as set forth in subsection (J), below.

 

(C)         Possession
of Collateral. In furtherance of the foregoing, the Borrower expressly agrees that, if a Default shall occur and be continuing,
the Bank may (i) by judicial powers, or without judicial process if it can be done without breach of the peace, enter any premises
where any of such Collateral is or may be located, and without charge or liability to the Bank seize and remove such Collateral
from such premises and (ii) have access to and use of the Borrower's books and records relating to such Collateral.

 

(D)         Sale
of Collateral.

 

(1)         The
Borrower expressly agrees that if a Default shall occur and be continuing, the Bank, without demand of performance or other demand
or notice of any kind (except the notice specified below of the time and place of any public or private sale) to the Borrower or
any other person (all of which demands and notices are hereby waived by the Borrower), may forthwith collect, receive, appropriate
and realize upon the Collateral and forthwith sell, lease, assign, give an option or options to purchase or otherwise dispose of
and deliver the Collateral or any part thereof (or contract to do so) in one or more parcels at public or private sale, at any
exchange, broker's board or at any office of the Bank or elsewhere in such manner as is commercially reasonable and as the Bank
may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Bank shall have the right
upon any such public sale, and, to the extent permitted by law, upon any such private sale, to purchase the whole or any part of
the Collateral so sold. The Borrower further agrees, at the Bank's request, to assemble the Collateral, and to make it available
to the Bank at places which the Bank may reasonably select. To the extent permitted by applicable law, the Borrower waives all
claims, damages and demands against the Bank arising out of the foreclosure, repossession, retention or sale of the Collateral.

 

(2)         Unless
the Collateral threatens to decline speedily in value or is of a type customarily sold in a recognized market, the Bank shall give
the Borrower five (5) days' written notice of its intention to make any such public or private sale or sale at a broker's board
or on a securities exchange. Such notice shall (a) in the case of a public sale, state the time and place fixed for such sale,
(b) in the case of a sale at a broker's board or on a securities exchange, state the board or exchange at which such sale is to
be made and the day on which the Collateral, or any portion thereof being sold, will first be offered for sale and (c) in the case
of a private sale, state the day after which such sale may be consummated. The Bank shall not be required or obligated to make
any such sale pursuant to any such notice. The Bank may adjourn any public or private sale or cause the same to be adjourned from
time to time by announcement at the time and place fixed for the sale, and such sale may be made at any time or place to which
the same may be so adjourned. In the case of any sale of all or any part of the Collateral for credit or for future delivery, the
Collateral so sold may be retained by the Bank until the selling price is paid by the purchaser thereof, but the Bank shall not
incur any liability in case of failure of such purchaser to pay for the Collateral so sold and, in the case of such failure, such
Collateral may again be sold upon like notice.

 

    	-33-

    	 

    

 

(E)         Rights
of Purchasers. Upon any sale of the Collateral (whether public or private), the Bank shall have the right to deliver, assign
and transfer to the purchaser thereof the Collateral so sold. Each purchaser (including the Bank) at any such sale shall hold the
Collateral so sold free from any claim or right of whatever kind, including any equity or right of redemption of the Borrower,
and the Borrower, to the extent permitted by law, hereby specifically waives all rights of redemption and any right to a judicial
or other stay or approval which it has or may have under any law now existing or hereafter adopted.

 

(F)         Additional
Rights of the Bank.

 

(1)         The
Bank shall have the right and power to institute and maintain such suits and proceedings as it may deem appropriate to protect
and enforce the rights vested in it by this Agreement and may proceed by suit or suits at law or in equity to enforce such rights
and to foreclose upon and sell the Collateral or any part thereof pursuant to the judgment or decree of a court of competent jurisdiction.

 

(2)         The
Bank shall, to the extent permitted by law and without regard to the solvency or insolvency at the time of any Person then liable
for the payment of any of the Obligations or the then value of the Collateral, and without requiring any bond from any party to
such proceedings, be entitled to the appointment of a special receiver or receivers (who may be the Bank) for the Collateral or
any part thereof and for the rents, issues, tolls, profits, royalties, revenues and other income therefrom, which receiver shall
have such powers as the court making such appointment shall confer, and to the entry of an order directing that the rents, issues,
tolls, profits, royalties, revenues and other income of the property constituting the whole or any part of the Collateral be segregated,
sequestered and impounded for the benefit of the Bank, and the Borrower irrevocably consents to the appointment of such receiver
or receivers and to the entry of such order.

 

(G)         Remedies
Not Exclusive.

 

(1)         No
remedy conferred upon or reserved to the Bank in this Agreement is intended to be exclusive of any other remedy or remedies, but
every such remedy shall be cumulative and shall be in addition to every other remedy conferred herein or now or hereafter existing
at law, in equity or by statute.

 

(2)         If
the Bank shall have proceeded to enforce any right, remedy or power under this Agreement and the proceeding for the enforcement
thereof shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Bank, the Borrower
and the Bank shall, subject to any determination in such proceeding, severally and respectively be restored to their former positions
and rights under this Agreement, and thereafter all rights, remedies and powers of the Bank shall continue as though no such proceedings
had been taken.

 

(3)         All
rights of action under this Agreement may be enforced by the Bank without the possession of any instrument evidencing any Obligation
or the production thereof at any trial or other proceeding relative thereto, and any suit or proceeding instituted by the Bank
shall be brought in its name and any judgment shall be held as part of the Collateral.

 

    	-34-

    	 

    

 

(H)         Waiver
and Estoppel.

 

(1)         The
Borrower, to the extent it may lawfully do so, agrees that it will not at any time in any manner whatsoever claim or take the benefit
or advantage of any appraisement, valuation, stay, extension, moratorium, turnover or redemption law, or any law now or hereafter
in force permitting it to direct the order in which the Collateral shall be sold which may delay, prevent or otherwise affect the
performance or enforcement of this Agreement and the Borrower hereby waives the benefits or advantage of all such laws, and covenants
that it will not hinder, delay or impede the execution of any power granted to the Bank in this Agreement but will permit the execution
of every such power as though no such law were in force; provided that nothing contained in this subsection (H) shall be
construed as a waiver of any rights of the Borrower under any applicable federal bankruptcy law.

 

(2)         The
Borrower, to the extent it may lawfully do so, on behalf of itself and all who may claim through or under it, including without
limitation any and all subsequent creditors, vendees, assignees and lienors, waives and releases all rights to demand or to have
any marshalling of the Collateral upon any sale, whether made under any power of sale granted herein or pursuant to judicial proceedings
or upon any foreclosure or any enforcement of this Agreement and consents and agrees that all the Collateral may at any such sale
be offered and sold as an entirety.

 

(3)         The
Borrower, to the extent it may lawfully do so, waives presentment, demand, protest and any notice of any kind (except notices explicitly
required hereunder) in connection with this Agreement and any action taken by the Bank with respect to the Collateral.

 

(I)         Power
of Attorney. The Borrower hereby irrevocably constitutes and appoints the Bank, with full power of substitution, as its true
and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Borrower and in the name of
the Borrower or in its own name, from time to time in the Bank's reasonable discretion for the purpose of carrying out the terms
of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary
or desirable to accomplish the purposes of this Agreement and, without limiting the generality of the foregoing, hereby gives the
Bank the power and right, on behalf of the Borrower, without notice to or assent by the Borrower to do the following:

 

(1)         to
pay or discharge Taxes, Liens, security interests or other encumbrances levied or placed on or threatened against the Collateral;

 

(2)         to
effect any repairs or any insurance called for by the terms of this Agreement and to pay all or any part of the premiums therefor
and the costs thereof; and

 

    	-35-

    	 

    

 

(3)         upon
the occurrence and continuance of any Default and otherwise to the extent provided in this Agreement, (a) to direct any party liable
for any payment under any of the Collateral to make payment of any and all moneys due and to come due thereunder directly to the
Bank or as the Bank shall direct; (b) to receive payment of and receipt for any and all moneys, claims and other amounts due and
to become due at any time in respect of or arising out of any Collateral; (c) to sign and indorse any invoices, freight or express
bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications and notices in connection
with accounts and other documents relating to the Collateral; (d) to commence and prosecute any suits, actions or proceedings at
law or in equity in any court of competent jurisdiction to collect the Collateral or any part thereof and to enforce any other
right in respect of any Collateral; (e) to defend any suit, action or proceeding brought against the Borrower with respect to any
Collateral; (f) to settle, compromise and adjust any suit, action or proceeding described above and, in connection therewith, to
give such discharges or releases as the Bank may deem appropriate; (g) to assign any patent or trademark (along with the goodwill
of the business to which such trademark pertains), for such term or terms, on such conditions, and in such manner, as the Bank
shall in its sole discretion determine; and (h) generally to sell, transfer, pledge, make any agreement with respect to or otherwise
deal with any of the Collateral as fully and completely as though the Bank were the absolute owner thereof for all purposes, and
to do, at the Bank's option and the Borrower's expense, at any time, or from time to time, all acts and things which the Bank deems
necessary to protect, preserve or realize upon the Collateral and the Bank's security interest therein, in order to effect the
intent of this Agreement, all as fully and effectively as the Borrower might do.

 

The Borrower hereby ratifies all that said
attorney shall lawfully do or cause to be done by virtue hereof. This power of attorney is a power coupled with an interest and
shall be irrevocable.

 

(J)          Application
of Proceeds. The Bank shall retain the net proceeds of any collection, recovery, receipt, appropriation, realization or sale
of the Collateral and, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care
and safekeeping of any or all of the Collateral or in any way relating to the rights of the Bank hereunder, including reasonable
attorneys' fees and legal expenses, apply such net proceeds to the payment in whole or in part of the Obligations in such order
as the Bank may elect, the Borrower remaining liable for any amount remaining unpaid (and any attorneys' fees paid by the Bank
in collecting such deficiency) after such application. Only after applying such net proceeds and after the payment by the Bank
of any other amount required by any provision of law, including Section 9-504(1)(c) of the UCC, need the Bank account for the surplus,
if any, to the Borrower or to whomsoever may be lawfully entitled to the same.

provided that the Borrower shall not be liable to any Indemnitee for any Liability caused solely by the gross negligence
or willful misconduct of such Indemnitee. In no event shall any Indemnitee, as a condition to enforcing its rights under this subsection
(D) or otherwise, be obligated to make a claim against any other person (including, without limitation, the Bank) to enforce its
rights under this subsection (D).

REVOLVING COMMERCIAL NOTE

 

IMPORTANT NOTICE

 

THIS INSTRUMENT CONTAINS A CONFESSION
OF JUDGMENT PROVISION WHICH CONSTITUTES A WAIVER OF IMPORTANT RIGHTS YOU MAY HAVE AS A DEBTOR AND ALLOWS THE CREDITOR TO OBTAIN
A JUDGMENT AGAINST YOU WITHOUT ANY FURTHER NOTICE.

 

	$15,000,000.00	June 30, 2014

 

FOR VALUE RECEIVED, on or before September
30, 2015 (hereinafter called "Date of Maturity") the undersigned (individually and collectively, the "Borrower")
jointly and severally promise to pay to the order of UNITED BANK (the "Bank," which term shall include any holder of
this Note) without offset, at the Bank's office located at 2071 Chain Bridge Road, Vienna, Virginia 22182 (or at such other address
as the Bank shall designate), the principal sum of Fifteen Million and no/100 Dollars ($15.000,000.00) (hereinafter called "Principal
Sum"), or so much of that sum as the Bank may advance, together with interest on the principal balance outstanding from time
to time at the rate provided in this Note.

 

This Note is an amendment and restatement
of, and replaces, that certain Amended and Restated Revolving Commercial Note dated September 13, 2012, in the original principal
amount of Fifteen Million and No/100 Dollars ($15,000,000.00), made by the Borrower payable to the order of the Bank, the obligations
of the Borrower under which are suspended.

 

This Note is the “Revolving Note”
referenced in the Loan Agreement. Reference is hereby made to the Loan Agreement for provisions of this Note with respect to conditions
for advances, remedies on Default, and other terms.

 

INTEREST RATE. This Note shall bear
interest on the principal balance outstanding from time to time, from the date of this Note until paid in full, a variable rate
per annum equal, at all times, to the Prime Rate minus one-half of one percent (0.50%); provided, however, that at
no time shall the interest rate on the Note be less than three and one-half percent (3.50%) per annum. The "Prime Rate"
shall mean that variable rate of interest published in The Wall Street Journal from time to time as the domestic prime rate
under the heading "Money Rates". If The Wall Street Journal shall cease to publish the Prime Rate, the term “Prime
Rate” shall thereafter mean the rate announced from time to time by the Bank as its prime rate of interest and evidenced
by a certificate signed by any officer of the Bank setting forth said prime rate of interest in effect on any given date, whether
or not such rate is otherwise published or announced. The Prime Rate is not necessarily the lowest rate charged by the Bank to
borrowers. Interest on this Note shall be calculated on the basis of a 360-day year, for the actual number of days elapsed.

 

    	Page 1 of 7

    	 

    

 

PAYMENT TERMS. The Borrower agrees
to pay accrued interest beginning July 30, 2014, and on the same day of each consecutive month thereafter until this Note is paid
in full. On the Date of Maturity, all outstanding principal, interest and fees under this Note shall be due and payable in full.

 

PREPAYMENT. The Borrower may pay the
whole or any part of the outstanding indebtedness evidenced by this Note at any time without penalty by paying the principal amount
to be prepaid together with accrued interest thereon to the date of prepayment.

 

ADVANCES. If no Default Condition (as
defined in the Loan Agreement) has occurred and is then continuing, the Borrower may borrow at any time and from time to time from
the date hereof to the Date of Maturity, such amounts as the Borrower may request, subject to the provisions hereof and of the
Loan Agreement.

 

DEFAULT. Each of the following events
or conditions shall constitute a default ("Default") under this Note:

 

(a)            the failure to make any payment of
principal, interest or any other amount due under this Note when such payment is due;

 

(b)           any default under the terms of any
of the Loan Documents, or the failure to perform or observe any warranty, covenant, or other condition of any of the Loan Documents;
and the failure to cure said event or condition within 20 calendar days after the earlier to occur of (i) the date of notice thereof
to the Borrower, and (ii) the date notice thereof should have been given to the Bank pursuant to Section VI(C)(1)(c) of the Loan
Agreement.

 

(c)           any default by the Borrower or any
indorser or guarantor of the payment of this Note with respect to any Debt to the Bank (other than this Note) or to any other creditor
or obligee;

 

(d)           the merger, consolidation, reorganization,
dissolution, or termination of existence of any Party; or the pledge, lease or other disposition, without the prior written approval
of the Bank, of all or substantially all of the assets of any Party;

 

(e)           any change, or any transaction which
results or could result in a change, in the Control of any Party;

 

(f)            the determination by the Bank that
any warranty, representation, certificate, statement or information provided by any Party or any Person on behalf of a Party to
the Bank in connection with any of the Loan Documents, or to induce the Bank to make or extend or modify the terms of the loan
evidenced by this Note, was false or misleading, or that any Party or any Person on behalf of a Party failed to provide or disclose
any facts or information, which failure rendered such warranty, representation, certificate, statement or information misleading;

 

    	Page 2 of 7

    	 

    

 

(g)           the inability of any Party to pay its
debts as they mature, the insolvency of any Party, the filing of a petition by or against any Party under the provisions of any
bankruptcy, reorganization, arrangement, insolvency, liquidation or similar law for relief of debtors, the appointment or application
for appointment of any receiver for any Party or the property of any Party, the issuance or service of any attachment, levy, garnishment,
tax lien or similar process against any Party or the property of any Party, the entry of a judgment against any Party, or an assignment
for the benefit of creditors by any Party; provided, however, that said Party shall have 20 calendar days to dismiss or
discharge any of the foregoing that is an involuntary proceeding;

 

(h)           any agreement or other document granting
the Bank security for the payment of this Note shall cease for any reason to be in full force and effect as such security with
the priority stated to be created thereby, or the grantor of such security shall contest the validity or enforceability of the
security or deny that it has any further liability or obligation under such agreement or other document;

 

(i)            any indorsement or guaranty of the
payment of this Note shall cease for any reason to be in full force and effect, or any indorser or guarantor shall contest the
validity or enforceability of the indorsement or guaranty or deny that it has any further liability or obligation under the indorsement
or guaranty; or

 

(j)            the determination by the Bank that
(i) there has occurred a material adverse change in the financial condition of any Party, (ii) the value of any property securing
this Note has been materially impaired, or (iii) there has occurred or developed an event or condition which materially impairs
the prospect of payment or performance of any of the obligations of any Party under the Loan Documents; and the failure of said
Party to cure said event or condition, or satisfy the Bank as to such event, condition, change or impairment, within 20 calendar
days after notice thereof to the Borrower.

 

ACCELERATION. At the option of the
Bank, upon the occurrence of a Default as defined above, the full amount remaining unpaid on this Note shall become immediately
due and payable without presentment, demand or notice of any kind; no additional advances shall be made to the Borrower under this
Note; and the Bank may exercise any or all remedies available to it under applicable law and the Loan Documents.

 

ACCOUNT RECORD. The Bank shall maintain
records of the dates and amounts of advances of principal and payments of principal and interest, the date to which interest has
been paid, accrued interest, the unpaid principal balance, and any other account information. Such records shall be maintained
unilaterally by the Bank without notice to the Borrower and shall be presumed to be correct, provided, however, any failure of
the Bank to maintain such records or any error therein or in any notice hereunder shall not in any manner affect the obligation
of the Borrower to pay this Note in accordance with the terms hereof.

 

IMMEDIATELY AVAILABLE FUNDS. The principal
of and interest on this Note shall be payable in immediately available funds in lawful money of the United States which shall be
legal tender for public and private debts at the time of payment. The making of any payment in other than immediately available
funds which the Bank, at its option, elects to accept shall be subject to collection, and interest shall continue to accrue until
the funds by which payment is made are available to the Bank for its use.

 

ADJUSTMENT TO BILLING NOTICE. If, because
a variable interest rate or the outstanding principal balance of this Note changes between the date of a billing notice and the
end of a billing period or the Date of Maturity, the actual amount due and payable is different from the amount billed, then the
amount billed must be paid. The next following billing notice shall be adjusted by the amount of the difference, or a supplemental
billing notice or rebate, as the case may be, shall be sent to the Borrower following the Date of Maturity. A supplemental billing
notice following the Date of Maturity shall be immediately due and payable in full.

 

    	Page 3 of 7

    	 

    

 

APPLICATION OF PAYMENTS. Payments will
be applied to interest, principal, and late charges and other charges due at the time such payments are received, in that order.
All payments shall be applied to satisfaction of scheduled payments in the order in which they become due.

 

CONFESSION OF JUDGMENT. The Borrower
appoints William L. Stauffer, Jr., Esquire, and W. Alexander Burnett, Esquire, either of whom may act, as its duly constituted
attorney-in-fact with authority, in the name, place, and stead of the Borrower, to confess judgment in the office of the clerk
of the Circuit Court of Fairfax County, Virginia against it, in the full amount due under this Note, upon the occurrence of a Default
under this Note. By a written instrument, the Bank may appoint a substitute for the above named attorneys-in-fact (or any of them).
If a copy of this Note, verified by an affidavit, shall have been filed in the proceeding, it will not be necessary to file the
original as a warrant of attorney. The Borrower waives the right to any stay of execution and the benefit of all exemption laws
now or hereinafter in effect. No single exercise of the foregoing warrant and power to confess judgment will be deemed to exhaust
the power, whether or not such exercise shall be held by any court to be invalid, voidable or void; but the power will continue
undiminished and may be exercised from time to time as the Bank may elect until all amounts owing on the Note shall have been paid
in full.

 

WAIVER. The Borrower and any indorser
of this Note (i) waive presentment, demand, protest and notice of dishonor and protest, (ii) waive the benefit of their homestead
exemptions as to this debt, (iii) waive any right which they may have to require the Bank to proceed against any other Party or
any collateral given to secure the payment of this Note, and (iv) agree that, without notice to the Borrower or any indorser and
without affecting the liability of the Borrower or any indorser, the Bank, at any time or times, may grant extensions of the time
for any payment due on this Note or any other indulgence or forbearance, release any Party from the obligation to make payments
on this Note, permit the renewal of this Note, or permit the substitution, exchange or release of any security for this Note.

 

LATE CHARGE; ATTORNEYS' FEES. If the
Borrower fails to pay any amount due under this Note within 7 days of the date due, the Borrower shall pay to the Bank on demand
a late charge equal to five percent (5%) of the amount due. The Borrower shall pay to the Bank on demand all costs incurred by
the Bank, and reasonable attorneys' fees, in the collection or enforcement of this Note in the event of Default, whether or not
suit is brought.

 

SET-OFF. The Bank will have the right,
in addition to all other remedies permitted by law (including, without limitation, other rights of set-off), to set off the amount
now or hereafter due under this Note or due under any other obligation of the Borrower to the Bank against any and all accounts,
credits, money, securities, or other property now or hereafter on deposit with, held by, or in the possession of the Bank to the
credit or for the account of the Borrower, without notice to or consent by the Borrower. In addition to the right of set-off, to
secure the payment of this Note the Borrower assigns and grants to the Bank a security interest in all accounts, credits, money,
securities, or other property now or hereafter on deposit with, held by, or in the possession of the Bank to the credit or for
the account of the Borrower.
