REVOLVING NOTE

			
	 	 	 
	$6,000,000.00
	 	As of March 2nd, 2006

     FOR VALUE RECEIVED, Horne Engineering Services, LLC, and Spectrum Sciences & Software Holdings
Corp. (jointly and severally, the “Borrower”), both having an address at c/o Horne Engineering
Services, LLC, 3130 Fairview Park Drive, Suite 400, Falls Church, Virginia 22042, promise to pay to
the order of Bank of America, N.A., a national banking association (the “Lender”), the principal
sum of Six Million and 00/100 Dollars ($6,000,000.00) (the “Principal Sum”), or so much thereof as
has been or may be advanced or readvanced to or for the account of the Borrower pursuant to the
terms and conditions of the Loan Agreement (as hereinafter defined), together with interest thereon
at the rate or rates hereinafter provided, in accordance with the following terms:

1. Interest.

     a. Commencing as of the date hereof and continuing thereafter, the unpaid Principal
Sum shall bear interest at a fluctuating annual rate equal to the LIBOR Rate (as hereafter
defined), plus Two and One Half of a percent (2.50%). The “LIBOR Rate” means the interest rate
determined by the following formula, rounded upward to the nearest 1/100 of one percent.

	 	 	 	 	 
	LIBOR Rate =

	 	London Inter-Bank Offered Rate	 	 
	 

	 	 	 	 
	 

	 	(1.00 - Reserve Percentage)	 	 

“London Inter-Bank Offered Rate” means the average per annum interest rate at which U.S. dollar
deposits would be offered for an “Interest Period” of one (1) month by major banks in the London
inter-bank market, as shown on the Telerate Page 3750 (or any successor page) at approximately
11:00 a.m. London time two (2) London Banking Days before the commencement of the Interest Period.
If such rate does not appear on the Telerate Page 3750 (or any successor page), the rate for that
Interest Period will be determined by such alternate method as reasonably selected by Lender. A
“London Banking Day” is a day on which Lender’s London Banking Center is open for business and
dealing in offshore dollars. “Reserve Percentage” means the total of the maximum reserve
percentages for determining the reserves to be maintained by member banks of the Federal Reserve
System for Eurocurrency Liabilities, as defined in Federal

 

 

Reserve Board Regulation D, rounded upward to the nearest 1/100 of one percent. The percentage will be
expressed as a decimal, and will include, but not be limited to,
marginal, emergency,
supplemental, special, and other reserve percentages. The first day of the Interest Period must
be a day other than a Saturday, or a Sunday on which Lender is open for business in New York and
London and dealing in offshore dollars (a “LIBOR Banking Day”). The last day of the Interest
Period and the actual number of days during the Interest Period will be determined by Lender using
the practices of the London inter-bank market. Absent manifest error, the Lender’s certificate to
the Borrower stating the LIBOR Rate for each Interest Period shall be conclusive.

     The rate at which interest shall accrue under this Note may change immediately upon any change
at the commencement of each Interest Period (if the London Inter-Bank Offered Rate has changed).

     All interest payable under the terms of this Note shall be calculated by applying a daily
interest rate, determined by multiplying the outstanding principal balance by the applicable annual
interest rate and dividing the resulting product by 360, to the actual number of days principal is
outstanding.

2. Payments and Maturity. The unpaid Principal Sum, together with interest thereon at the
rate or rates provided above, shall be payable as follows:

     a. interest shall be due and payable monthly, commencing on the first day of the first
calendar month after the date of this Note, and on the first day of each succeeding calendar month.

     b. unless sooner paid, the unpaid Principal Sum, together with all interest accrued and unpaid
thereon, and all other amounts owing under this Note shall be due and payable in full on April 30,
2007 (the “Maturity Date”). If the Loan Agreement provides for the Borrower to make additional
payments on account of the Principal Sum from time to time, Borrower promises to make those
payments at the time and in the manner specified in the Loan Agreement.

3. Default Interest. Upon the occurrence of an Event of Default (as hereinafter defined),
the unpaid Principal Sum shall bear interest thereafter, until the Event of Default is cured, at a
rate of two percent (2%) per annum in excess of the rate or rates of interest that would otherwise
be in effect under this Note.

4. Late Charges. If the Borrower fails to make any payment under the terms of this Note
within ten (10) days after the date such payment is due, the Borrower shall pay to the Lender on
demand a late charge equal to five percent (5%) of such payment.

5. Application and Place of Payments. Except as otherwise provided in the Loan Agreement
(hereinafter defined), all payments, made on account of this Note shall be applied

2

 

first to the payment of accrued and unpaid interest then due hereunder, second to the unpaid principal
balance and the remainder, if any, shall be applied to any other
amounts which remain owing
hereunder. All payments on account of this Note shall be paid in lawful money of the United States
of America in immediately available funds during regular business hours of the Lender at its office
at 1101 Wootton Parkway, 4th Floor, Rockville, Maryland 20852, or at such other times
and places as the Lender may at any time and from time to time designate in writing to the
Borrower.

6. Loan Agreement. This Note is the “Revolving Note” described in a Revolving Line of
Credit Loan Agreement and Security Agreement of even date herewith by and between the Borrower and
the Lender (the “Loan Agreement”). The indebtedness evidenced by this Note is included within the
meaning of the term “Debt” as defined in the Loan Agreement. The term “Loan Documents” as used in
this Note shall have the meaning ascribed to that term in the Loan Agreement. Capitalized terms
used in this Note but not defined herein have the meanings ascribed to them in the Loan Agreement.

7. Security. This Note is secured by the Collateral described in the Loan Agreement.

8. Events of Default. The occurrence of any one or more of the following events shall
constitute an event of default (individually, an “Event of Default” and collectively, the “Events
of Default”) under this Note:

     a. the failure of the Borrower to pay to the Lender when due any amount payable by the
Borrower to the Lender under the terms of this Note, or the failure of the Borrower to perform any
other obligation under the terms of the Note; or

     b. the occurrence of an event of default under any of the other Loan Documents.

9. Remedies. Upon the occurrence of an Event of Default, at the option of the Lender, all
principal, accrued interest and other sums payable by the Borrower to the Lender under the terms of
this Note shall become immediately due and payable, and the Lender shall have all of the rights,
powers, and remedies available under the terms of this Note, any of the other Loan Documents and
all applicable laws. The Borrower and all endorsers hereby jointly and severally waive
presentment, protest and demand, notice of protest, notice of demand and of dishonor and
non-payment of this Note and expressly agree that this Note or any payment hereunder may be
extended from time to time without in any way affecting the liability of the Borrower or any
endorsers.

     Confession of Judgment. The Borrower hereby appoints Joseph P. Corish and Jennifer A.
Brust, and each of them, as the Borrower’s true and lawful attorney-in-fact, for the Borrower, in
the Borrower’s name, place and stead, to confess judgment against the Borrower, if an Event of
Default should occur, in the Circuit Court of Fairfax County, Virginia, for the principal
outstanding under this Note, together with interest, late payment charges, court costs and

3

 

attorney’s fees equal to fifteen percent (15%) of the unpaid principal balance for which judgment
is confessed, hereby ratifying and confirming the acts of said attorney-in-fact as fully as if done
by the Borrower. The Borrower consents to immediate execution of any such confessed
judgment and waives the benefit of any exemption laws. No single exercise of the foregoing 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 Lender may elect until all amounts owing under this Note have been
paid in full.

10. Expenses. The Borrower promises to pay to the Lender on demand by the Lender all costs
and expenses incurred by the Lender in connection with the collection, enforcement and/or defense
of this Note, including, without limitation, all attorneys’ fees and expenses, all court costs and
all arbitration fees and costs.

11. Notices. Any notice, request, or demand to or upon the Borrower or the Lender shall be
deemed to have been properly given or made when delivered in accordance with the Loan Agreement.

12. Miscellaneous. Each right, power, and remedy of the Lender as provided for in this
Note or any of the other Loan Documents, now or hereafter existing under any applicable law or
otherwise, shall be cumulative and concurrent and shall be in addition to every other right, power,
or remedy provided for in this Note or any of the other Loan Documents now or hereafter existing
under any applicable law, and the exercise or beginning of the exercise by the Lender of any one or
more of such rights, powers, or remedies shall not preclude the simultaneous or later exercise by
the Lender of any or all such other rights, powers, or remedies. No failure or delay by the Lender
to insist upon the strict performance of any term, condition, covenant, or agreement of this Note
or any of the other Loan Documents, or to exercise any right, power, or remedy available upon a
breach thereof, shall constitute a waiver of any such term, condition, covenant, or agreement or of
any such breach, or preclude the Lender from exercising any such right, power, or remedy at a later
time or times. By accepting payment after the due date of any amount payable under the terms of
this Note, the Lender shall not be deemed to waive the right either to require prompt payment when
due of all other amounts payable under the terms of this Note or to declare an Event of Default for
the failure to effect such prompt payment of any such other amount. No course of dealing or
conduct shall be effective to amend, modify, waive, release, or change any provisions of this Note.

13. Partial Invalidity. If any term or provision of this Note or the application thereof
to any person or circumstance shall be invalid or unenforceable to any extent, the remainder of
this Note and the application of such term or provision to persons or circumstances other than
those as to which it is held invalid or unenforceable shall not be affected thereby, and each term
and provision of this Note shall be valid and be enforceable to the fullest extent permitted by
law.

14. Captions. The captions herein set forth are for convenience only and shall not be
deemed to define, limit, or describe the scope or intent of this Note.

4

 

15. Governing Law. The provisions of this Note shall be construed, interpreted and
enforced in accordance with the laws of the Commonwealth of Virginia (excluding Virginia’s choice
of law rules).

16. Consent to Jurisdiction. Provisions of the Loan Agreement concerning the Borrower’s
consent to the jurisdiction of state and federal courts sitting in the Commonwealth of Virginia are
incorporated into this Note by reference and shall have the same force and effect as if fully set
forth in this Note.

17. Waiver of Trial by Jury. Provisions of the Loan Agreement concerning the Borrower’s
and Lender’s mutual waiver of trial by jury in disputes between the Borrower and the Lender are
incorporated into this Note by reference and shall have the same force and effect as if fully set
forth in this Note.

18. Arbitration. Provisions of the Loan Agreement specifying that certain disputes between
the Borrower and the Lender shall be resolved by binding arbitration are incorporated into this
Note by reference and shall have the same force and effect as if fully set forth in this Note.

persons comprised by the term Borrower shall be joint and several. References in this Note to the
Borrower shall refer to each such person or to all of them as the context may require. Any notice

11

 

2.1 Revolving Line of Credit. The Lender agrees to extend the Revolving Loan to Borrower,
subject to the terms and conditions of this Agreement. Until the Ending Date, Borrower may borrow,
repay and reborrow Advances in accordance with this Agreement.

     a. Allowed Amount of Advances. The aggregate principal amount of Advances outstanding
at any time shall not exceed the lesser of:

     1. the difference between (i) the Maximum Revolving Commitment Amount and (ii) the LOC
Obligations; or

     2. the difference between (i) the Borrowing Base and (ii) the LOC Obligations.

     b. Mandatory Prepayments. If the principal outstanding under the Revolving Loan, at
any time exceeds the Allowed Amount of Advances, then Borrower shall make an immediate payment of
principal under the Revolving Loan in an amount sufficient that the principal outstanding under the
Revolving Loan will no longer exceed the Allowed Amount of Advances. If the amount of the
Borrower’s Funded Debt at any time exceeds the maximum amount that will enable Borrower to comply
with any of the affirmative covenants provided hereinafter (including, without limiting the
generality of the foregoing, any covenant limiting the Borrower’s ratio of Funded Debt to EBITDA),
then Borrower shall make an immediate payment of principal under the Revolving Loan in an amount
sufficient to enable Borrower to comply with all applicable financial covenants provided
hereinafter.

     c. Procedure for Advances. Unless Borrower has previously entered into a separate auto
borrow or similar cash management service with Lender, Borrower may request Advances by telephone
through its employees or agents, as hereinafter provided. Each Advance request must be received by
Lender not later than 1:00 p.m. (Eastern Standard time) on the date the Advance is to be made and
must specify the amount of the Advance. Lender shall deposit the Advance into Borrower’s Operating
Account if Borrower is entitled to the Advance, subject to the terms and conditions of this
Agreement. If Borrower has entered into a separate auto borrow or similar cash management service
with Lender, then the provisions of such service shall control with respect to the procedures for
making Advances to Borrower. Lender shall have the right to terminate such auto borrow or similar
cash management service at any time, as determined by Lender in its sole and absolute discretion.

     d. Letter of Credit Subfacility. At Lender’s discretion, Lender shall issue Letters
of Credit for the account of the Borrower from time to time upon request from the Closing Date
until the Ending Date, subject to the following terms and conditions:

     1. the aggregate amount of LOC Obligations shall at no time exceed the Letter of Credit
Sublimit;

12

 

     2. any request for a Letter of Credit to be issued must be delivered and received by
Lender not later than five (5) business days prior to the date that Borrower wishes to have
the Letter of Credit issued;

     3. no Letter of Credit shall have an original expiry date more than one year from the
date of issuance or beyond the Ending Date unless otherwise agreed to by Lender in writing
or unless Borrower’s obligation to reimburse Lender for drawings under the Letter of Credit
has been fully secured by a cash deposit with the Lender;

     4. Borrower shall execute and deliver to Lender a Letter of Credit Agreement
with respect to each Letter of Credit to be issued by Lender, using the Lender’s standard
reimbursement agreement form at the time the Letter of Credit is issued. The form and
substance of each Letter of Credit, and any reimbursement agreement required by Lender in
relation to a Letter of Credit, must be satisfactory to the Lender, in its sole judgment;

     5. issuance of the Letter of Credit shall not cause the aggregate outstanding principal
amount of all Advances to exceed the Allowed Amount of Advances, determined taking into
account the increase in the amount of the LOC Obligations caused by the issuance of the
Letter of Credit;

     6. Lender shall not be required to issue any Letter of Credit if any circumstance
exists that would entitle Lender not to honor a request for an Advance under the Revolving
Loan;

     7. upon notice from Lender of any drawing under any Letter of Credit, Borrower shall,
as to be determined in Lender’s sole and absolute discretion, either (a) deliver cash to
Lender, in an amount satisfactory to secure all LOC Obligations and all amounts payable by
the Borrower to the Lender under any Letter of Credit Agreement pertaining to such LOC
Obligations, or (b) immediately reimburse Lender for the amount of the drawing, plus
interest from the date of the drawing at the highest rate of interest then in effect under
the Revolving Note. The Borrower’s obligation to reimburse the Lender for any drawing under
a Letter of Credit shall be absolute and unconditional, irrespective of any rights of
set-off, counterclaim or defense to payment the Borrower may claim or have against the
Lender, the beneficiary of the Letter of Credit or any other Person;

     8. unless the Borrower makes reimbursement from another source on the day of the
drawing under any Letter of Credit, the Borrower shall be deemed to have requested an
Advance under the Revolving Loan in the amount of the drawing, and (i) Lender, at its
option, may make such an Advance (irrespective of whether Borrower would then be entitled to
an Advance under the terms of this Agreement) and apply the proceeds of the Advance to
satisfy the Borrower’s obligation to reimburse Lender for the

13

 

amount drawn on the Letter of Credit; and (ii) any such Advance shall be repayable,
with interest, in accordance with the terms and conditions of the Revolving Note; and

     9. the provisions of the Letter of Credit Agreement pertaining to each Letter of
Credit are deemed incorporated into this Agreement by this reference and shall be binding
upon the Lender and Borrower as if fully set forth herein. If a conflict exists between the
terms of the Letter of Credit Agreement and any other Loan Document, the terms of the Letter
of Credit Agreement shall control with respect to the Letter of Credit issued pursuant to
that Letter of Credit Agreement but not as to other matters governed by this Agreement or
such Loan Document.

2.2 Repayment of Revolving Loan; Auto Debit. Borrower promises to repay the Revolving
Loan, with interest, at the time and in the manner and in accordance with the terms provided in the
Revolving Note. Borrower has elected to authorize Lender to effect payment of sums due under the
Revolving Note and this Agreement by means of debiting Borrower’s account with Lender, account
number 004134369781. This authorization shall not affect the obligation of Borrower to pay such
sums when due, without notice, if there are insufficient funds in such account to make payment in
full on the due date thereof, or if Lender fails to debit the account.

2.3 Use of Revolving Loan Proceeds. The proceeds of the Revolving Loan shall be used for
working capital, for capital expenditures and to finance the performance of Government Contracts,
and for no other purpose.

2.4 Revolving Loan Fees. Borrower promises to pay Lender the following fees in
consideration of entering into this Agreement. These fees are in addition to interest payable
under the Revolving Note:

     a. an unused fee for each day that any part of the Maximum Revolving Commitment Amount is
unused. The unused fee shall be calculated and payable quarterly, in arrears, commencing on the
first day of the first fiscal quarter of Borrower after the date of this Agreement. The unused fee
shall be determined for each day by multiplying the part of the Maximum Revolving Commitment Amount
that is unused on that day by a per-diem rate equal to .35, divided by 360.

     b. the fees and costs associated with each field examination performed by the Lender or its
agents, for up to two (2) field examinations per year. However, the Lender shall have the right to
perform such additional field examinations at any time, in its sole discretion. Each additional
field examination will be at Lender’s own expense if no Event of Default has occurred and remains
uncured at the time of the additional field examination, but shall be at the Borrower’s expense if
an Event of Default has occurred and remains uncured at the time of the additional field
examination.

14

 

     c. an annual letter of credit fee for each day that any Letter of Credit is outstanding. The
letter of credit fee shall be calculated and payable in advance of the issuance of such Letter of
Credit. The letter of credit fee for each Letter of Credit to be issued in accordance with this
Agreement shall be determined by multiplying the amount of such Letter of Credit by a per-annum
rate equal to 1.50, divided by 360. Borrower shall also be obligated to pay to Lender, on demand,
the Lender’s standard fees then in effect for issuance of Letters of Credit and/or any amendments
thereto.

     ARTICLE 3. CONDITIONS PRECEDENT TO LOAN.

obligation of Borrower to Lender whether now or hereafter existing, of every kind and description,
whether or not evidenced by notes or other instruments, and whether or not such liability or
obligations are direct or indirect, fixed or contingent, liquidated or unliquidated, the Borrower
hereby assigns, grants and conveys to the Lender a security interest in the Collateral. In
addition, except as provided by law, Borrower grants to Lender a security interest in all deposit
accounts and other bank accounts of Borrower with Lender or any of Lender’s Affiliates. Proceeds
of the Collateral shall be allocated pari passu among the Loan and any outstanding interest
rate swap agreements. The Borrower further agrees that the Lender shall have in respect of the
Collateral all of the rights and remedies of a secured party under the Uniform Commercial Code,

and hereby authorizes Lender to prepare and file with the financing records for such jurisdictions
as Lender deems appropriate, such financing statements and other instruments and filings or perform

thereof, other than in the ordinary course of its business or as otherwise may be permitted by this
Agreement.

estate unless subordination agreements satisfactory to the Lender are obtained by any owner or

     b. The Lender’s security interest shall extend and attach to Inventory which is presently in
existence and is owned by the Borrower or in which the Borrower purchases or acquires an interest
at any time and from time to time in the future, whether such Inventory is in transit or in the
Borrower’s constructive, actual or exclusive occupancy or possession or not, and wherever the same
may be located, including, without limitation, all Inventory which may be located at the premises
of the Borrower or upon the premises of any carriers, forwarding agents, truckers, warehousemen,
vendors, selling agents, finishers, convertors or other third parties who may have possession of
the Inventory.

     c. Upon sale, exchange, lease or disposition of the Inventory or Equipment, the security
interest of the Lender shall without break in continuity and without further formality or act
continue in and attach to all cash and non-cash proceeds of such sale, exchange, lease or
disposition, including Inventory returned or rejected by customers or repossessed by either the
Borrower or the Lender. As to any such sale, exchange, lease or disposition, the Lender shall have
all of the rights of an unpaid seller, including stoppage in transit, replevin, detinue and
reclamation.

(i) to pay any taxes or levies on the Collateral or any costs to repair or to preserve the
Collateral; and (ii) to cure any defaults by Borrower on contracts by the Borrower intended to give

request of the Lender, Borrower will execute financing statements, continuation statements and
other documents with respect to the Collateral pursuant to the Uniform Commercial Code or

all public offices wherever the Lender deems filing to be necessary or desirable. Borrower agrees
that a carbon, photographic, photostatic or other reproduction of this Agreement or of a financing
statement is sufficient as a financing statement, provided however, that it shall not limit the
obligations of Borrower as previously set forth herein. Borrower grants the Lender the right, and
hereby authorizes Lender, at the Lender’s option, to file any or all such financing statements,
continuation statements and other documents pursuant to the UCC and otherwise, without Borrower’s
signature, and irrevocably appoints the Lender as Borrower’s attorney-in-fact to execute any such
statements and documents in Borrower’s name and to perform all other acts which the Lender deems
appropriate to perfect and to continue the security interests conferred by this Agreement.

In addition, upon request of Lender, Borrower shall immediately deliver to Lender, or authorize and
direct any and all Persons in possession of Collateral, to immediately deliver to Lender all
Collateral for which Lender requires possession to perfect its security interest in such
Collateral, properly endorsed or acknowledged. Furthermore, Borrower shall take all such actions
as may

19

 

be requested by Lender to allow Lender to exercise control over any Collateral for such purpose of
allowing Lender to perfect its security interest in Collateral, which Collateral may include
Deposit Accounts, Investment Property, Letter-of-Credit Rights and electronic Chattel Paper. At
Lender’s request, Borrower shall execute and deliver to Lender, and have any other Persons in
possession or control of Collateral, execute and deliver to Lender, control or other agreements, in
form and substance satisfactory to Lender.

4.5 Records of Collateral; Information. Borrower at all times will maintain accurate books
and records covering the Collateral. Borrower immediately will mark all books and records with an
entry showing the absolute assignment of and granting of a security interest in all Collateral to
Lender, and hereby grants the Lender the right to audit the books and records of Borrower relating
to Collateral at any time and from time to time. Borrower shall (i) promptly furnish the Lender
with any information with respect to Collateral requested by Lender; (ii) allow the Lender or its
representatives to inspect the Collateral, at any time and wherever located and in whomever’s
possession the Collateral may be, and to inspect and copy, or furnish the Lender or its
representatives with copies of all records relating to the Collateral; (iii) furnish the Lender or
its representatives such information as the Lender may request to identify the Collateral, at the
time and in the form requested by Lender; and (iv) deliver upon request to Lender shipping and
delivery receipts evidencing the shipment of goods and invoices evidencing the receipt of the
Collateral and payment for the Collateral.

4.6 No Release. No injury to the Collateral, loss or destruction of the Collateral,
failure to perfect or to continue the perfection of Lender’s security interest in the Collateral,
or release of Lender’s security interest in the Collateral, or any part of it, shall relieve
Borrower of any obligation under this Agreement or under any of the other Loan Documents. Borrower
expressly waives all defenses based on suretyship or impairment of collateral, and shall not be
released or discharged of any obligation under the Loan Documents, in whole or in part, by Lender’s
failure to protect or preserve the Collateral. No Person, in deciding to enter into this Loan
Agreement, has relied on the execution of this Loan Agreement or the granting of a security
interest in Collateral by any other Person. Each Person comprised by the term Borrower waives
notice of any change in financial condition of any Person liable for the Loans or any part thereof,
and agrees that maturity of the Loans or any part thereof may be accelerated, extended or renewed
one or more times by Lender in its discretion, without notice to the Person and without affecting
Lender’s security interest in the Collateral. Lender shall not be required to bring any action
against any other Person or to resort to any other security or to any balance of any deposit
account as a condition of enforcing its rights against any of the Collateral.

4.7 Assignment of Payments Under Certain Government Contracts and Government Accounts. On
the Closing Date, and thereafter upon the creation of any Government Contract or Government
Account, Borrower shall, at Lender’s option, execute and deliver to the Lender specific Assignments
of Payments due or to become due with respect to any Government Account designated by the Lender
which has at least Two Hundred Fifty Thousand and 00/100 Dollars ($250,000.00) in payment
obligations to Borrower and which has a duration of at least six months. Borrower shall execute
and deliver any and all documents and take any and all steps

20

 

necessary to provide the Lender with an Assignment. The separate Assignment to the Lender of a
right to payment under specific Government Contracts, as contemplated under this Section, shall not
be deemed to limit the Lender’s security interest to Payments under those particular Government
Contracts and the related Government Accounts, but rather the Lender’s security interest, as stated
above, shall extend to Payments under any and all Government Contracts and the related Government
Accounts and proceeds thereof, now or hereafter owned or acquired by Borrower.

4.8 Additional Remedy for Failure to Assign Payments. Borrower acknowledges that the
Lender will be irreparably harmed if Borrower fails to assign Payments due or to become due under
any Government Contract when required by this Agreement, and that the Lender shall have no adequate
remedy at law. Therefore, the Borrower agrees that the Lender shall be entitled to the following
remedies, in addition to all other remedies allowed by law or under this Agreement,

     a. an injunction compelling Borrower’s compliance with the provisions of this Agreement
requiring the Borrower to assign Payments due or to become due under any Government Contract;

     b. the appointment of a receiver, within instructions that the receiver shall comply, in the
Borrower’s name and on its behalf, with the provisions of this Agreement requiring the Borrower to
assign Payments due or to become due under any Government Contract; and

     c. such other or further equitable relief as may be necessary or desirable to secure to Lender
the benefits of the rights of an assignee under the Assignment of Claims Act.

4.9 Indemnification; Risk of Loss. In any suit, proceeding or action brought by or
against the Lender relating to the Collateral, the Borrower will defend, indemnify and keep the
Lender harmless from and against all expense, loss or damage (including reasonable attorneys’ fees)
suffered by reason of any defense, set-off, counterclaim, recoupment or reduction of liability
whatsoever of account debtor or other obligor of the Borrower. The foregoing obligation of the
Borrower to indemnify the Lender shall survive the payment of the Loans and the termination of this
Agreement, but shall not extend to any suit, proceeding or action arising out of the Lender’s gross
negligence or willful misconduct.

In addition, the risk of any loss or damage associated with the Collateral, including without
limitation, any Collateral in the possession of Lender shall be borne by the Borrower; provided,
that Lender shall be responsible for any loss resulting from Lender’s gross negligence or willful
misconduct. In the event that Lender is in possession of Collateral, (a) Borrower shall be liable
to Lender and shall pay to Lender, upon demand, all reasonable expenses, including the cost of
insurance and payment of taxes or other charges, incurred in the custody, preservation, use or
operation of the Collateral, and all such expenses shall be secured by the Collateral; and (b)
Lender may use and operate the Collateral, as determined in its sole and absolute discretion, (i)
to preserve the Collateral or its value, (ii) as permitted by an order of a court having competent

21

 

jurisdiction, or (iii) as otherwise set forth herein or as previously or hereafter agreed to by
Borrower. Notwithstanding anything in this Agreement to the contrary, Lender shall have no duty
and be under no obligation to collect any income accruing on the Collateral or to preserve any
rights relating to the Collateral.

perform the transactions contemplated by this Agreement or the other Loan Documents.

23

Borrower has paid all taxes, assessments and other government charges imposed upon it or its

or any of its properties. Borrower is not in default with respect to any Debt. Borrower will take
all necessary actions to remain in full compliance with such laws, ordinances, rules, regulations,
orders and any other requirements, the Governance Documents and all other agreements. Should
Borrower be deemed by any governmental authority or deem itself to be in violation of any relevant
law, ordinance, rule, regulation, orders or other requirement, Governance Document or agreement,
Borrower shall notify the Lender promptly of such violation and take all necessary remedial
actions. Without limiting the generality of the foregoing, Borrower represents to Lender that: (1)

any such product or service, may infringe any trademark, trade name, copyright, patent, trade
secret or legally protected right of any other Person.

Intellectual Property used in and material to the operation of its business or, for such
Intellectual Property that is not owned, possesses adequate licenses or other legally enforceable

which a claim adversely affecting any such Intellectual Property may be asserted against the
Borrower or any subsidiary. To the best knowledge of the Borrower, no Person is infringing upon
the Intellectual Property used by the Borrower or any subsidiary material to the operation of their
respective businesses. The Borrower has taken appropriate steps to protect the secrecy,
confidentiality and value of its and all subsidiaries’ rights in and to such Intellectual Property

Multiemployer Plan is, to the best knowledge of the Borrower, reasonably expected to be in
reorganization, insolvent or terminated.

4975 of the Code) or breach of fiduciary responsibility has occurred with respect to a Plan which
has subjected or may subject the Borrower or any of its subsidiaries or any ERISA Affiliate to any
liability under Sections 406, 409, 502(I), or 502(l) of ERISA or Section 4975 of the Code, or under

Fifty Thousand and 00/100 Dollars ($250,000.00) in payment obligations to Borrower and which has a

Accounts in intervals not greater than thirty (30) days, and shall contain such other information
and be accompanied by such supporting documents as the Lender may from time to time prescribe.
Borrower also shall deliver to the Lender copies of Borrower’s invoices, evidences of shipment or
delivery and such other schedules and information as the Lender may reasonably require. The items
to be provided under this Section are to be prepared and delivered to the Lender from time to time
solely for its convenience in maintaining records of the Collateral, and Borrower’s failure to give
any of such items to the Lender shall not affect, terminate, modify or otherwise limit the Lender’s
security interest granted in the Accounts. Without limiting the generality of the foregoing,
Borrower shall promptly notify the Lender when Borrower obtains any new Government Contract or
Government Account for which Payments are to be specifically assigned to the Lender pursuant to
this Agreement, and Borrower shall furnish to the Lender, upon request, a copy of each Government
Contract of Borrower and a copy of each amendment thereto or modification thereof which changes the
price of such contract or the amount funded to pay for such contract, except to the extent that
furnishing such copies may be prohibited by government security regulations. Borrower shall use
its best efforts and shall take any and all steps necessary to collect its Accounts, including
without limitation, the filing and pursuit of legal action in furtherance of said collection
efforts.

6.13 Collateral. Maintain all tangible Collateral in good condition; insure
insurable Collateral for its full replacement cost under an insurance policy acceptable to Lender
that names Lender as lender loss payee; execute, deliver and file, or cause the execution, delivery
and filing of, any and all documents (including without limitation, financing statements and
continuation statements), necessary or desirable for the Lender to create, perfect, preserve,
validate or otherwise protect a first priority lien and security interest in the Collateral;
maintain, or cause to be maintained, at all times, the Lender’s first priority lien and security
interest in the Collateral; immediately upon learning thereof, report to the Lender any
reclamation, return or repossession of any goods forming a part of the Collateral, any claim or
dispute asserted by any debtor or other obligor owing an obligation to Borrower, and any other
matters affecting the value or enforceability or collectibility of any of the Collateral; defend
the Collateral against all claims and demands of all Persons at any time claiming the same or any
interest therein adverse to the Lender, and pay all costs and expenses (including attorneys’ fees
and expenses) incurred in

31

 

connection with such defense; at Borrower’s sole cost and expense (including attorneys’ fees and
expenses), settle any and all claims, demands and disputes, and indemnify and protect the Lender
against any liability, loss or expenses arising from any such claims, demands or disputes or out of
any such reclamation, return or repossession of goods forming a part of the Collateral; however, if
the Lender shall so elect, the Lender shall have the right at all times to settle, compromise,
adjust or litigate all claims and disputes directly with the Customer or other obligor owing an
obligation to Borrower upon such terms and conditions as the Lender deems advisable, and all costs
and expenses thereof (including attorneys’ fees and expenses) shall be incurred for the account of
Borrower and shall constitute a part of the obligations owed to the Lender and secured pursuant to
this Agreement. The Borrower’s Equipment shall be kept and maintained at the locations set forth
in said Schedule 5.1; Borrower shall not relocate or move the Equipment without the
Lender’s prior written consent, which shall not be unreasonably withheld. If Lender consents to
the relocation of certain Equipment, Borrower shall execute all documents or financing statements
and take such action as Lender may request to assure that Lender’s first priority security interest
in the Equipment continues to be perfected under the Uniform Commercial Code or other applicable
laws.

6.14 Financial Covenants. Maintain:

     a. Minimum EBITDA. A minimum EBITDA, as follows: (i) Four Hundred Thousand and 00/100
Dollars ($400,000.00) for the six month period ending on June 30, 2006, (ii) Seven Hundred Thousand
and 00/100 Dollars ($700,000.00) for the nine month period ending on September 30, 2006, and (iii)

     b. Tangible Net Worth. A minimum Tangible Net Worth of Nineteen Million and 00/100
Dollars ($19,000,000.00) at all times from the closing of the Loan to the Ending Date.

Compliance with financial covenant 6.14 a. above shall be calculated from the financial statements
of Borrower for the calendar quarters of Borrower included in such period, which are to be
delivered by Borrower to Lender by the end of the quarter immediately following the last day of the
period for which such calculation is being made (e.g., the calculation of minimum EBITDA for the
period ending June 30, 2006 will be made from the financial statements of Borrower for the quarters
ending on March 31, 2006 and June 30, 2006, said financial statements being due by no later than
September 30, 2006).

Compliance with financial covenant 6.14 b. will be subject to calculation at all times.

6.15 Notice of Litigation, Default and Loss. Give immediate notice to the Lender
upon the occurrence of any Event of Default or event which with notice or lapse of time or
otherwise would constitute an Event of Default, and of any loss or damage to any of the Collateral.
Borrower also shall give immediate notice to the Lender of any action, suit or proceeding at law
or in equity or by or before any governmental instrumentality or agency (domestic or foreign),
commission, board, bureau, arbitrator or arbitration panel which, if adversely determined, could

32

 

materially impair or affect the right of Borrower to carry on its business substantially as now
conducted or could materially affect its respective business, operations, prospects, properties,
assets (including the Collateral) or condition, financial or otherwise. Immediately upon becoming
aware that the holder of any Debt or Encumbrance has given notice or taken any action with respect
to a claimed breach, default or event of default (including without limitation, any such action or
notice initiated, provided or taken by Tatonka Capital Corporation, or its affiliates, successors
or assigns), a written notice shall be given by Borrower to Lender specifying the notice given or
action taken by such holder and the nature of the claimed breach, default or event of default by
the Borrower thereunder, and the action being taken or proposed to be taken with respect thereto.
Borrower shall also give immediate notice to Lender of the incurrence by Borrower of any actual or
potential contingent liability, such notice to include, in detail, the basis for and amount of such
liability.

6.16 Proxy Statements, Etc. Promptly after the sending or filing thereof, copies of all
proxy statements, financial statements and reports which the Borrower sends to its stockholders,
and copies of all regular, periodic and special reports, and all registration statements which the
Borrower files with the Securities and Exchange Commission or any governmental authority which may
be substituted therefor, or with any national securities exchange.

6.17 ERISA. Give prompt notice to Lender of any of the following: (i) of any event or
condition, including, but not limited to, any Reportable Event, that constitutes, or might
reasonably lead to, a Termination Event; (ii) with respect to any Multiemployer Plan, the receipt

ERISA); (iii) the failure to make full payment on or before the due date (including extensions)
thereof of all amounts which the Borrower or any of its subsidiaries or ERISA Affiliate is required
to contribute to each Plan pursuant to its terms and as required to meet the minimum funding
standard set forth in ERISA and the Code with respect thereto; or (iv) any change in the funding
status of any Plan that could have a material adverse effect on the Borrower’s financial condition;
together, with a description of any such event or condition or a copy of any such notice and a
statement by the principal financial officer of the Borrower briefly setting forth the details
regarding such event, condition, or notice, and the action, if any, which has been or is being
taken or is proposed to be taken by Borrower with respect thereto. Promptly upon request, the
Borrower shall furnish to Lender such additional information concerning any Plan as may be
reasonably requested, including, but not limited to, copies of each annual report/return (Form 5500
series), as well as all schedules and attachments thereto required to file with the Department of
Labor or the Internal Revenue Service pursuant to ERISA and the Code, respectively, for each “plan
year” (within the meaning of Section 3(39) of ERISA). Such notice shall be given in any event
within five (5) business days after the occurrence of any event that Borrower is required to report
to Lender under this clause.

which consent the Lender agrees not to unreasonably withhold.

the Federal Reserve System; or for any purpose other than the purposes or purposes specified

which would be violated or breached by Borrower’s performance of its obligations under the Loan

terms no less favorable to the Borrower than would be applicable in a comparable arm’s-length
transaction with a Person not an Affiliate.

     ARTICLE 8. COLLECTION, DEPOSIT AND ASSIGNMENT OF PAYMENTS.

8.1 Operating Account. While the Loan remains in effect and until such time as Lender has
no further obligations hereunder, Borrower shall cause all Payments to be deposited into the
Operating Account, subject to Lender’s option to require Payments to be deposited into a Cash
Collateral Account, as provided in Section 8.2.

8.2 Cash Collateral Account. Lender may, at its option, require the establishment
of a Cash Collateral Account, in which event, Borrower shall cause all Payments to be deposited
into the Cash Collateral Account. In furtherance of this covenant, Borrower shall instruct all
Customers to make all Payments either by electronic funds transfer directly to the Cash Collateral
Account or by check to a post office box or other collection facility under Lender’s control for
deposit into the Cash Collateral Account. If any Payments are made directly to the Borrower or
otherwise come into the Borrower’s possession, the Borrower shall not commingle any such Payment
with the Borrower’s other funds or property, but shall hold the Payment separate and apart in trust
for the Lender and shall promptly deliver the Payment to the Lender (appropriately endorsed, if the
Payment is in the form of a check) for deposit into the Cash Collateral Account. Interest (if any)
earned on sums on deposit in the Cash Collateral Account shall be added to the Cash Collateral
Account. The Borrower hereby appoints the Lender and any officer, employee or agent of the Lender
as the Lender may from time to time designate as attorneys-in-fact for the Borrower to endorse and
sign the name of the Borrower on all checks, drafts, money orders or other Items delivered to the
Lender for deposit into the Cash Collateral Account. The Cash Collateral Account shall constitute
part of the Collateral, and funds on deposit in the Cash Collateral Account shall be applied
towards the amounts due and owing under the Revolving Note, this Agreement and/or the other Loan
Documents as determined by Lender in its sole and absolute discretion, and provided no event of
default has occurred and remains uncured, the remaining funds shall be deposited into Borrower’s
Operating Account. If an Event of Default has occurred and remains uncured, Payments received by
Lender shall be applied as the Lender may determine in its sole discretion. Borrower retains the
sole responsibility for assuring the Borrower’s Operating Account contains sufficient funds to pay
an Items that may be presented for payment from the Operating Account.

8.3 Overdrafts. At Lender’s sole option in each instance, Lender may do one of the
following:

36

 

     a. Lender may make Advances under the Revolving Note to prevent or to cover an overdraft on
account of Borrower with Lender. Each such Advance will accrue interest from the date of the
Advance or the date on which the account is overdrawn, whichever occurs first, at the interest rate
described in the Revolving Note. Lender may make such Advances even if the Advances may cause the
balance owing under the Revolving Note to exceed the Maximum Revolving Loan Commitment Amount; or

     b. Lender may reduce the amount of credit otherwise available under the Revolving Note by the
amount of any overdraft on any account of Borrower with Lender.

This section shall not be deemed to authorize Borrower to create overdrafts on any of Borrower’s
accounts with Lender.

     ARTICLE 9. EVENTS OF DEFAULT AND REMEDIES.

9.1 Events of Default. The occurrence of any one or more of the following events shall
constitute an Event of Default under this Agreement:

     a. Borrower shall fail to pay, when due, any sum payable under the Revolving Note; or

other Loan Documents which, in the Lender’s judgment, shall prove to have been materially incorrect

subsidiaries) or for any substantial part of Borrower’s (or any of Borrower’s subsidiaries) assets
or property shall be appointed, or the winding up or liquidation of Borrower’s (or any of
Borrower’s subsidiaries) affairs shall be ordered, or any action by any creditor (other than the
Lender) of Borrower (or any of Borrower’s subsidiaries) preparatory to or for the purpose of
commencing any such involuntary case, appointment, winding up or liquidation shall be taken, and
such proceeding shall not have been dismissed within thirty (30) days after the date it commenced;
or

     d. Borrower (or any of Borrower’s subsidiaries) shall commence a voluntary case under any
bankruptcy, insolvency or similar law now or hereafter in effect, or Borrower (or any of Borrower’s
subsidiaries) shall consent to the entry of an order for relief in an involuntary case under any
such law or to the appointment of or taking possession by a receiver, liquidator or other similar
agent for Borrower (or any of Borrower’s subsidiaries) or for any substantial part of Borrower’s
(or any of Borrower’s subsidiaries) assets or property, or Borrower (or any of

37

 

Borrower’s subsidiaries) shall make any general assignment for the benefit of creditors, or
Borrower shall take any action preparatory to or otherwise in furtherance of any of the foregoing,

come due; or

of maturity; or

have not been vacated, discharged, stayed or bonded pending appeal within thirty (30) days from the
entry thereof, or any attachment or garnishment shall be issued against Borrower or Borrower’s
property or any subsidiaries of Borrower of any property of such subsidiaries; or

     h. any material change in the business, operations, property, assets or condition (financial
or otherwise) of Borrower shall occur which adversely affects the ability of Borrower to meet and
carry out its obligations under this Agreement or any of the other Loan Documents or to perform the
transactions contemplated herein or thereby, the materiality of such change to be determined by the
Lender in its sole discretion; or

     i. any investigative proceeding, audit or other action shall be initiated by or on behalf of
any Customer, which is based upon a claim or contest with respect to any Government Contract or
Government Account that, if adversely determined to the Borrower, would have a material adverse
effect on the Borrower’s financial condition, as determined by the Lender in its sole discretion;
or

     j. the issuance to the Borrower of any cure notice, show-cause notice, or notice of
whole or partial termination, for default or alleged default, under any contract which is either a
Government Contract or is a subcontract (at any tier) which is related to a contract between a
third party and the Government; or

     k. with respect to the Borrower, the occurrence of any debarment or suspension from

     p. any of the following events or conditions shall occur: (1) any “accumulated funding
deficiency,” as such term is defined in Section 302 of ERISA and Section 412 of the Code, whether
or not waived, shall exist with respect to any Plan, or any lien shall arise on the assets of the
Borrower or any of its subsidiaries or any ERISA Affiliate in favor of the PBGC or a Plan; (2) a
Termination Event shall occur with respect to a Single Employer Plan, which, in the Lender’s
opinion, is likely to result in the termination of such Plan for purposes of Title IV of ERISA; (3)
a Termination Event shall occur with respect to a Multiemployer Plan or Multiple Employer Plan,
which in the Lender’s opinion, is likely to result in (i) the termination of such Plan for purposes
of Title IV of ERISA, or (ii) the Borrower or any of its subsidiaries or any ERISA Affiliate
incurring any liability in connection with a withdrawal from, reorganization of (within the meaning
of Section 4241 of ERISA), or insolvency or (within the meaning of Section 4245 of ERISA) such
Plan; or (4) any prohibited transaction (within the meaning of Section 406 of ERISA or Section 4975

without limitation, any Swap Agreement) with the Lender or any of Lender’s Affiliates to be
observed or performed on its part and such default shall continue unremedied for a period of ten
(10) Business Days after written notice of the existence of such default is given by Lender. The
cure period described in this paragraph is inapplicable to the Events of Default listed in the
paragraphs above.

If one of the foregoing events or circumstances occurs to which a cure period applies, Lender will
not exercise its rights and remedies under this Agreement to collect the Loans except as Lender
reasonably deems necessary to protect its interests in the Collateral, but Lender shall not be
required to make any new Loans or other financial accommodations unless and until the default is
timely cured under this Agreement. Notwithstanding anything in this Agreement to the contrary, any
right to cure a default is applicable only to defaults for which a cure period has been provided,
and only to the occurrence of a single default during any one calendar year period.

39

 

Borrower shall have no right to cure more than one default in any one calendar year period, nor
shall Borrower have the right at any time to cure any default for which no cure period has been
provided.

9.2 Rights and Remedies of the Lender. Upon the occurrence of any Event of Default, the
Lender may, at its option, exercise any one or more of the following rights and remedies:

     a. Declare this Agreement and the Lender’s obligation to make or extend any Advances on the
Revolving Loan to be terminated, and declare the entire unpaid principal amounts of the Revolving
Loan, all interest accrued and unpaid thereon, and all other amounts payable under this Agreement
and the other Loan Documents to be accelerated, and to be immediately due and payable (except that
upon the occurrence of an Event of Default arising out of voluntary or involuntary bankruptcy
proceedings in which the Borrower is the debtor, such acceleration shall occur automatically and
immediately without any declaration or other action on the part of the Lender) whereupon the
Revolving Loan, all such accrued interest, and all such amounts shall become and be immediately due
and payable, without presentment, demand, protest or further notice of any kind, all of which are
hereby expressly waived by Borrower, anything contained herein or in any of the other Loan
Documents to the contrary notwithstanding;

     b. Take possession or control of, store, lease, operate, manage, sell or otherwise
dispose of all or any part of the Collateral in accordance with the remedies provided to secured
parties under the Uniform Commercial Code, this Agreement, the Loan Documents or other applicable
law. In taking possession of the Collateral, the Lender may enter the Borrower’s premises and
otherwise proceed without legal process, and the Borrower shall on the Lender’s demand, promptly
assemble and make the Collateral available to the Lender at a place designated by the Lender. The
Lender shall be entitled to immediate possession of all books and records evidencing or pertaining
to any of the Collateral. In the event of any sale or other disposition of the Collateral, Lender
may disclaim any warranty relating to title, possession, quiet enjoyment or any other warranty of
the like, including without limitation, any warranty of merchantability or fitness for a particular
purpose;

     c. Notify any or all Customers to make any Payments due to Borrower from such Customers
directly to the Lender and render performance to or for the benefit of Lender of any obligations of
such Customers to Borrower. To facilitate direct collection, Borrower hereby appoints the Lender
and any officer or employee of the Lender, as the Lender may from time to time designate, as
attorney-in-fact for Borrower to (i) receive, open and dispose of all mail addressed to Borrower
and take therefrom any Payments on or proceeds of Accounts; (ii) take over Borrower’s post office
boxes or make such other arrangements, in which Borrower shall cooperate, to receive Borrower’s
mail, including notifying the post office authorities to change the address for delivery of mail
addressed to Borrower to such address as the Lender shall designate; (iii) endorse the name of
Borrower in favor of the Lender upon any and all checks, drafts, money orders, notes, acceptances
or other evidences of payment or Collateral that may come into the Lender’s possession; (iv) sign
and endorse the name of Borrower on any invoice or bill of lading relating to any of the Accounts,
on verifications of Accounts sent to any Customer,

40

 

to drafts against any Customer, to assignments of Accounts, and to notices to any Customer;
and (v) do all acts and things necessary to carry out this Agreement and the transactions
contemplated hereby, including signing the name of Borrower on any instruments required by law in
connection with the transactions contemplated hereby and on financing statements as permitted under
the Uniform Commercial Code of any appropriate state. Borrower hereby ratifies and approves all
acts of such attorneys-in-fact, and neither the Lender nor any other such attorney-in-fact shall be
liable for any acts of commission or omission, or for any error of judgment or mistake of fact or
law of any such attorney-in-fact. This power, being coupled with an interest and given to secure
an obligation, is irrevocable so long as the Revolving Loan remains unsatisfied, or any Loan
Document remains effective, as solely determined by the Lender. Lender shall have no obligation or
duty to pursue any Person other than Borrower for the amounts owing under or in connection with the
Revolving Loan, this Agreement or the other Loan Documents, including without limitation, any
Persons pledging property to secure the Loans. To the extent such rights may now or hereafter
exist, Borrower waives the right to require Lender to pursue any Persons other than Borrower to pay
the amounts owing under the Revolving Note, Loan Agreement or other Loan Documents;

     d. In the Lender’s own name, or in the name of Borrower, demand, collect, receive, sue for and
give receipts and releases for, any and all amounts due on Accounts, but the Lender shall not,
under any circumstances, be liable for any error or omission or delay of any kind occurring in the
settlement, collection or payment of any Accounts or any instrument received in payment thereof or
for any damage resulting therefrom;

     e. Endorse as the agent of Borrower any chattel paper, documents or instruments forming
all or any part of the Collateral;

     f. Make formal application for the transfer of all of Borrower’s permits, licenses, approvals,
agreements and the like relating to the Collateral or to Borrower’s business to the Lender or to
any assignee of the Lender or to any purchaser of any of the Collateral;

     g. Obtain appointment of a receiver for all or any of the Collateral, Borrower hereby
consenting to the appointment of such a receiver and agreeing not to oppose any such appointment.
Any receiver so appointed shall have such powers as may be conferred by the appointing authority
including any or all of the powers, rights and remedies which the Lender is authorized to exercise
by the Loan Documents, and shall have the right to incur such obligations and to issue such
certificates therefor as the appointing authority shall authorize;

     h. Take any other action which the Lender deems necessary or desirable to protect and realize
upon its security interest in the Collateral;

     i. File any legal action or lawsuit and obtain a judgement for any and all amounts owing under
the Revolving Note, this Agreement or the other Loan Documents, and in conjunction with any such
action, Lender may pursue any ancillary remedies provided by law, including without limitation,
attachment, garnishment, execution and levy;

41

 

     j. Borrower acknowledges that any failure to comply with its obligation regarding the
Collateral, including (without limiting the generality of the foregoing) granting of Assignments
and collection of the Accounts, shall cause irreparable harm to the Lender for which the Lender has
no adequate remedy at law, and agrees that the Lender shall be entitled to specific performance, an
injunction or other equitable relief to enforce the Borrower’s obligations under this Agreement;
and

     k. In addition to the foregoing, and not in substitution therefor, exercise any one or more of
the rights and remedies exercisable by the Lender under other provisions of this Agreement, under
any of the other Loan Documents, or provided by applicable law (including, without limiting the
generality of the foregoing, the Uniform Commercial Code), including without limitation, generally
enforcing any or all of the Borrower’s rights and remedies against any Customers, provided that
Lender shall be under no obligation to do so.

9.3 Application of Proceeds. Any proceeds from the collection or sale or other disposition
of the Collateral shall be applied in the following order of priority:

          First, to the payment of all expenses of collecting, storing, leasing,
operating, managing, selling or disposing of the Collateral, and to the payment of all sums which
the Lender may be required or may elect to pay, if any, for taxes, assessments, insurance and other
charges upon such Collateral or any part thereof, and of all other payments which the Lender may be
required or authorized to make under any provision of this Agreement or of any other Loan Document
(including in each such case legal costs and attorneys’ fees and expenses);

          Second, to the payment of all obligations on the Revolving Loan under this Agreement,
and under the other Loan Documents, and to the payment of any other obligations due to the Lender,
in such order as the Lender may determine in its sole discretion; and

          Third, to the payment of any surplus then remaining to Borrower, unless otherwise
provided by law or directed by a court of competent jurisdiction; provided that Borrower shall be
liable for any deficiency if the proceeds of the Collateral are insufficient to satisfy all
obligations due to the Lender.

9.4 Collection/Enforcement Costs. Borrower shall pay all costs and expenses incurred by
Lender in connection with the enforcement of its rights under this Agreement and the other Loan
Documents, including without limitation, legal costs and attorneys’ fees (whether or not suit is
instituted), paralegal and expert witness fees and costs, and arbitration fees and costs, and in
connection with the collection of any sums from Borrower.

     ARTICLE 10. MISCELLANEOUS PROVISIONS.

10.1 Additional Actions and Documents. Borrower shall take or cause to be taken such
further actions, shall execute, deliver and file or cause to be executed, delivered and filed such
further documents and instruments, and shall obtain such consents as may be necessary or

42

 

as the Lender may reasonably request in order fully to effectuate the purposes, terms and
conditions of this Agreement and the other Loan Documents, whether before, at or after the closing
of transactions contemplated hereby and thereby or the occurrence of an Event of Default hereunder,
including without limitation, executing such documents and taking such further actions as requested
by Lender to evidence or perfect the security interest(s) granted in accordance with this
Agreement, to maintain a first priority security interest in the Collateral for the benefit of
Lender, or to effectuate the rights of Lender hereunder.

10.2 Expenses. Borrower shall, whether or not the transactions contemplated hereby
are consummated, (i) reimburse the Lender and save the Lender harmless against liability for the
payment of all out-of-pocket expenses arising in connection with: (a) the preparation, execution,
delivery or filing of this Agreement or any of the Loan Documents; or (b) the administration or
enforcement of this Agreement or any of the Loan Documents; or (c) the preservation or exercise of
any rights (including the right to collect and dispose of the Collateral) under this Agreement or
any of the other Loan Documents; and (ii) pay and hold the Lender and each subsequent holder of the
Revolving Note harmless from and against, any and all present and future stamp taxes or similar
document taxes or recording taxes and any and all charges with respect to or resulting from any
delay in paying, or failure to pay, such taxes. Without limiting the generality of the foregoing,
the expenses covered by this paragraph include the Lender’s legal fees, the costs of audits or
examinations conducted by the Lender’s employees and any arbitration fees or court costs.

10.3 Notices. Except a may otherwise be provide herein, all notices, demands, requests or
other communications provided for herein or in the other Loan Documents shall be in writing and
shall be deemed to be effective one (1) day after dispatch if sent by Federal Express or any other
commercially recognized overnight delivery service or two (2) days after dispatch if sent by
registered or certified mail, return receipt requested and addressed as follows:

If to Borrower:

c/o Horne Engineering Services, LLC

3130 Fairview Park Drive, Suite 400

Falls Church, Virginia 22042

Attention: Darryl K. Horne

If to Lender:

Bank of America, N.A.

Joseph P. Corish

Bean, Kinney & Korman, P.C.

2000 N. 14th Street, Suite 100

Arlington, Virginia 22201

If the Borrower comprises more than one Person, notice to the Borrower at the address specified
above in this section for Horne Engineering Services, LLC shall constitute notice to all such
Persons, and each Person signing below as the Borrower hereby irrevocably appoints Horne
Engineering Services, LLC as that Person’s agent to receive notices from the Lender under this
Agreement or the other Loan Documents.

Each party may designate by notice in writing a new address to which any notice, demand,
request or communication thereafter may be so given, served or sent. Each notice, demand, request
or communication which is mailed, delivered or transmitted in the manner described above shall be
deemed sufficiently given, served, sent or received for all purposes at such time as it is
delivered: (i) to the United States Postal Service, in the case of a notice given by certified
mail; (ii) to Federal Express or any other commercially recognized overnight delivery service, in
accordance with the terms and procedures for such delivery.

Any notices required under the Uniform Commercial Code with respect to the sale or other
disposition of the Collateral shall be deemed reasonable if mailed by the Lender to the Persons
entitled thereto at their last known address at least ten (10) days prior to disposition of the
Collateral.

10.4 Severability. If fulfillment of any provision of the Loan Documents or performance of
any transaction related thereto, at the time such fulfillment or performance shall be due, shall
involve transcending the limit of validity prescribed by law, then the obligation to be fulfilled
or performed shall be reduced to the limit of such validity; and if any clause or provision
contained in any Loan Document operates or would operate prospectively to invalidate any Loan
Document, in whole or in part, then such clause or provision only shall be held ineffective, as
though not herein or therein contained, and the remainder of the Loan Documents shall remain
operative and in full force and effect.

10.5 Survival. It is the express intention and agreement of the parties hereto that all
covenants, agreements, statements, representations, warranties and indemnities made by Borrower in
the Loan Documents shall survive the execution and delivery of the Loan Documents and the making of
all Advances and extensions of credit thereunder.

10.6 Waivers. No waiver by the Lender of, or consent by the Lender to, a variation from
the requirements of any provision of the Loan Documents shall be effective unless made in a written
instrument duly executed on behalf of the Lender by its duly authorized officer, and any such
waiver shall be limited solely to those rights or conditions expressly waived.

44

 

10.7 Rights Cumulative. The rights and remedies of the Lender described in any of the Loan
Documents are cumulative and not exclusive of any other rights or remedies which the Lender or the
then holder of the Revolving Note otherwise would have at law or in equity or otherwise. No notice
to or demand on Borrower in any case shall entitle Borrower to any other notice or demand in
similar or other circumstances.

10.8 Entire Agreement; Modification; Benefit. This Agreement, the Schedules hereto,
and the other Loan Documents constitute the entire agreement of the parties hereto with respect to
the matters contemplated herein, supersede all prior oral and written agreements with respect to
the matters contemplated herein, and may not be modified, deleted or amended except by written
instrument executed by the parties. All terms of this Agreement and of the other Loan Documents
shall be binding upon, and shall inure to the benefit of and be enforceable by, the parties hereto
and their respective successors and assigns; however, Borrower may not assign or transfer any of
its rights or obligations hereunder without the prior written consent of the Lender. In the event
of any conflict between the terms of this Agreement and the terms of the other Loan Documents, the
terms of this Agreement shall control.

10.9 Setoff. In addition to any rights or remedies of the Lender provided by law, upon the
occurrence of any Event of Default hereunder, or any event or circumstance which, with the giving
of notice or the passage of time or both, would constitute an Event of Default hereunder, the
Lender is irrevocably authorized, at any time or times without prior notice to Borrower, to set
off, appropriate and apply any and all deposits, credits, indebtedness or claims at any time held
or owing by the Lender to or for the credit or the account of Borrower, in such amounts as the
Lender may elect, against and on account of the obligations and liabilities of Borrower to the
Lender hereunder or under any of the other Loan Documents, whether or not the Lender has made any
demand for payment, and although such obligations and liabilities may be contingent or unmatured.

10.10 Construction. This Agreement and the other Loan Documents, the rights and
obligations of the parties hereto, and any claims or disputes relating thereto shall be governed by
and construed in accordance with the laws of the Commonwealth of Virginia (excluding the choice of
law rules thereof) except to the extent that the UCC provides for either (a) the application of the
laws of the state in which Borrower maintains its chief executive office, (b) the application of
the laws of the state in which the collateral is located, (c) the application of the laws of the
state in which the Debtor is located or (d) otherwise mandates the application of the laws of
another state or jurisdiction. Each party hereto hereby acknowledges that all parties hereto
participated equally in the negotiation and drafting of this Agreement and that, accordingly, no
court construing this Agreement shall construe it more stringently against one party than against
the other.

10.11 Pronouns. All pronouns and any variations thereof shall be deemed to refer to the
masculine, feminine, neuter, singular or plural, as the identity of the Person may require.

45

 

10.12 Headings. Article, section and subsection headings contained in this Agreement are
inserted for convenience of reference only, shall not be deemed to be a part of this Agreement for
any purpose, and shall not in any way define or affect the meaning, construction or scope of any of
the provisions hereof.

10.13 Payments. If any payment or performance of any of the obligations under this
Agreement or any of the other Loan Documents becomes due on a day other than a Business Day, the
due date shall be extended to the next succeeding Business Day, and interest thereon (if
applicable) shall be payable at the then applicable rate during such extension.

10.14 Execution. To facilitate execution, this Agreement and any of the other Loan
Documents may be executed in as many counterparts as may be required; and it shall not be necessary
that the signature of, or on behalf of, each party, or the signatures of all Persons required to
bind any party, appear on each counterpart; but it shall be sufficient that the signature of, or on
behalf of, each party, or the signatures of the Persons required to bind any party, appear on one
or more of the counterparts. All counterparts shall collectively constitute a single agreement.
It shall not be necessary in making proof of this Agreement or any other Loan Document to produce
or account for any particular number of counterparts; but rather any number of counterparts shall
be sufficient so long as those counterparts contain the respective signatures of, or on behalf of,
all of the parties hereto.

10.15 Consent to Jurisdiction. Subject to any provision of this Agreement requiring that
disputes be submitted to arbitration, the Borrower irrevocably consents to the jurisdiction of any
state or federal court sitting in the Commonwealth of Virginia over any suit, action, or proceeding
arising out of or relating to this Agreement or the other Loan Documents. The Borrower irrevocably
waives, to the fullest extent permitted by law, any objection that the Borrower may now or
hereafter have to the laying of venue of any such suit, action, or proceeding brought in any such
court, or any claim that any such suit, action, or proceeding brought in any such court has been
brought in an inconvenient forum. Final judgment in any such suit, action, or proceeding brought
in any such court shall be conclusive and binding upon the Borrower.

10.16 Service of Process. The Borrower consents to process being served in any suit,
action or proceeding by mailing a copy thereof by registered or certified mail postage prepaid,
return receipt requested, to the Borrower’s address specified in or designated in this Agreement.
The Borrower agrees that such service (I) shall be deemed in every respect effective service of
process upon the Borrower in any such suit, action or proceeding and (ii) shall, to the fullest
extent permitted by law, be taken and held to be valid personal service upon and personal delivery
to the Borrower. Nothing in this Section shall affect the right of the Lender to serve process in
any manner permitted by law, or limit any right that the Lender may have to bring proceedings
against the Borrower in the courts of any jurisdiction or to enforce in any lawful manner a
judgment obtained in one jurisdiction in any other jurisdiction.

46

 

10.17 Sale of Loan Documents; Disclosure of Information. Borrower hereby consents to and
agrees that Lender may disclose to any Person any and all information connected with or related to
the Revolving Loan or other Loan Documents for the purpose of selling or assigning any rights of
Lender in the Loan Documents. The information which may be disclosed by Lender includes but is not
limited to all Loan Documents, credit files and correspondence files and all other writings and
oral communications which Lender wishes to disclose, in its sole and absolute discretion. Borrower
also hereby consents to and agrees that Lender may sell or assign any rights of Lender in any or
all of the Loan Documents pursuant to such terms and conditions as may be acceptable to Lender in
its sole and absolute discretion, to any interested Person, and nothing in this Agreement or the
other Loan Documents shall prevent, delay or otherwise impede or effect the right of Lender to
immediately sell or assign any rights of Lender in the Loan Documents on such terms as it deems
acceptable.

10.18 Arbitration and Waiver of Jury Trial.

     (a) This paragraph concerns the resolution of any controversies or claims between the
parties, whether arising in contract, tort or by statute, including but not limited to
controversies or claims that arise out of or relate to: (i) this Agreement (including any renewals,
extensions or modifications); or (ii) any document related to this Agreement; (collectively a
“Claim”). For the purposes of this arbitration provision only, the term “parties” shall include
any parent corporation, subsidiary or affiliate of Lender involved in the servicing, management or
administration of any obligation described or evidenced by this Agreement.

     (b) At the request of any party to this Agreement, any Claim shall be resolved by binding
arbitration in accordance with the Federal Arbitration Act (Title 9, U.S. Code) (the “Act”). The
Act will apply even though this Agreement provides that it is governed by the law of a specified
state. The arbitration will take place on an individual basis without resort to any form of class
action.

     (c) Arbitration proceedings will be determined in accordance with the Act, the then-current
rules and procedures for the arbitration of financial services disputes of the American Arbitration
Association or any successor thereof (“AAA”), and the terms of this paragraph. In the event of any
inconsistency, the terms of this paragraph shall control. If AAA is unwilling or unable to (i)
serve as the provider or arbitration or (ii) enforce any provision of this arbitration clause, any
party to this Agreement may substitute another arbitration organization with similar procedures to
serve as the provider of arbitration.

     (d) The arbitration shall be administered by AAA and conducted, unless otherwise required by
law, in any U.S. state where real or tangible personal property collateral for this credit is
located or if there is no such collateral, in the state specified in the governing law section of
this Agreement. All Claims shall be determined by one arbitrator; however, if Claims exceed
$5,000,000, upon the request of any party, the Claims shall be decided by three arbitrators. All
arbitration hearings shall commence within 90 days of the demand for arbitration and close within
90 days of commencement and the award of the arbitrator(s) shall be issued

47

 

within 30 days of the close of the hearing. However, the arbitrator(s), upon a showing of
good cause, may extend the commencement of the hearing for up to an additional 60 days. The
arbitrator(s) shall provide a concise written statement of reasons for the award. The arbitration
award may be submitted to any court having jurisdiction to be confirmed, judgment entered and
enforced.

     (e) The arbitrator(s) will give effect to statutes of limitation in determining any
Claim and may dismiss the arbitration on the basis that the Claim is barred. For purposes of the
application of the statute of limitations, the service on AAA under applicable AAA rules of a
notice of Claim is the equivalent of the filing of a lawsuit. Any dispute concerning this
arbitration provision or whether a claim is arbitrable shall be determined by the arbitrator(s).
The arbitrator(s) shall have the power to award legal fees pursuant to the terms of this Agreement.

     (f) This paragraph does not limit the right of the any party to: (i) exercise self-help
remedies, such as but not limited to, setoff; (ii) initiate judicial or nonjudicial foreclosure
against any real or personal property collateral; (iii) exercise any judicial or power of sale
rights, or (iv) act in a court of law to obtain an interim remedy, such as but no limited to,
injunctive relief, writ of possession or appointment of a receiver, or additional or supplementary
remedies.

     (g) The filing of a court action is not intended to constitute a waiver of the right of any
party, including the suing party, thereafter to require submittal of the Claim to arbitration.

     (h) By agreeing to binding arbitration, the parties irrevocably and voluntarily waive any
right they may have to a trial by jury in respect of any Claim. Furthermore, without intending in
any way to limit this Agreement to arbitrate, to the extent any Claim is not arbitrated, the
parties irrevocably and voluntarily waive any right they may have to a trial by jury in respect of
such Claim. This provision is a material inducement for the parties entering into this Agreement.
