Borrower shall not request any advance of proceeds of the Line of Credit which exceeds the Maximum Line of Credit Amount or the Borrowing Base or which would cause the aggregate amount of advances made and outstanding under the Line of Credit to exceed the Maximum Line of Credit Amount or the Borrowing Base. If the aggregate amount of advances made and outstanding under the Line of Credit shall at any time and for any reason exceed the Maximum Line of Credit Amount or the Borrowing Base, Borrower shall immediately pay Bank the excess. Each advance shall be by automatic credit. Bank shall make all advances by depositing funds in Borrower’s commercial account number 20-65310679 or such Bank account as may be agreed upon by Borrower and Bank. Borrower shall use the proceeds of the Line of Credit for short term working capital purposes including the financing of Borrower’s contracts and accounts receivable.

Borrower shall not request any advance of proceeds of the Auxiliary Revolver Facility which exceeds the Auxiliary Maximum Credit Amount or the Auxiliary Borrowing Base or which would cause the aggregate amount of advances made

With respect to each advance and all matters and transactions in connection therewith, Borrower hereby irrevocably authorizes Bank to accept, rely upon, act upon and comply with any oral or written instructions, requests, confirmations and orders of any employee or representative of Borrower who is so authorized or designated as a signer of Loan documents under the provisions of Borrower’s most recent Banking and Borrowing Resolutions or similar document on file with Bank. Borrower acknowledges that the transmission between Borrower and Bank of any such instructions, requests, confirmations and orders involves the possibility of errors, omissions, mistakes and discrepancies and agrees to adopt such internal measures and operational procedures as may be necessary to protect its interest. By reason thereof, Borrower hereby assumes all risk of loss and responsibility for, releases and discharges Bank from any and all responsibility or liability for, and agrees to indemnify, reimburse on demand and hold Bank harmless from, any and all claims, actions, damages, losses, liability and expenses by reason of, arising out of, or in any way connected with or related to: (i) Bank’s accepting, relying and acting upon, complying with or observing any such instruction, request, confirmation or order; and (ii) any such error, omission, mistake, or discrepancy, provided such error, omission, mistake or discrepancy is not the result of negligence on the part of Bank. Borrower may request an advance under the Auxiliary Revolver Facility only if such request is accompanied with documents, acceptable to the Bank in its sole discretion, supporting the request and indicating that the proceeds of such advance will be used only for a Permitted Auxiliary Use.
	C.		Evidence of Loan; Terms of Repayment. The interest rates on the Loan and the method of calculating interest upon the Loan, the term of the Loan, the method and times of repayment, and other conditions pertaining to the repayment of the Loan shall at the option of Bank be evidenced by Bank’s form of promissory note or as otherwise set forth in appropriate writings between the parties as determined by Bank. The Loans shall be subject to annual internal reviews of the Bank concurrent with the delivery of the Borrowers’ annual modified financial statements. In the absence of a promissory note or other applicable writing, the Loan shall be deemed to be otherwise conclusively evidenced by Bank’s record of advances of proceeds of the Loan and Bank’s record of receipt of repayments and other bookkeeping entries reflecting the payment of principal and interest, and interest shall be deemed to accrue at the interest rate reflected on Bank’s records.
	D.		Statement of Account. Bank may at any time or from time to time render a statement or statements of account to Borrower for the Obligations or any portion thereof. Each such statement shall be deemed to be correct and conclusively binding on Borrower unless Borrower notifies Bank to the contrary in writing within thirty (30) days from the date of any such statement which Borrower deems to be incorrect.
	E.		ARTS Fee. Borrower shall pay Bank a monthly ARTS fee of $1,000 per month subject to change as announced by the Bank from time to time. Bank may debit Borrower’s operating account to effectuate such payment, payable in arrears.
	F.		Unused Commitment Fee. Borrower agrees to pay an unused commitment fee on any difference between the Maximum Line of Credit Amount and the amount of advances under the Line of Credit, determined by the average of the daily amount of credit outstanding during the specified period. The fee will be calculated by multiplying such difference by one-quarter percent (0.25%). This fee is due on September 30, 2006, and on the last day of each following quarter until the Line of Credit has been terminated, payable in arrears. Bank may debit Borrower’s operating account to effectuate such payment.

Borrower constitutes Bank or Bank’s designee as Borrower’s attorney-in-fact with power with respect to the Receivables: (i) to endorse Borrower’s name upon any notes, acceptances, checks, drafts, money orders or other evidences of payment of Collateral that may come into Bank’s possession; (ii) to sign Borrower’s name on any invoices relating to any of the Receivables, drafts against Account Debtors, assignments and verifications of Receivables and notices to Account Debtors; (iii) to notify the post office authorities to change the address for delivery of mail addressed to Borrower to such address as Bank may designate; (iv) to receive, open, and dispose of mail addressed to Borrower; (v) to do all other acts and things necessary, proper, or convenient to carry out the terms and conditions and purposes and intent of this Agreement. The power of attorney hereby granted, being coupled with an interest, is irrevocable while any of the Obligations remain unpaid or unperformed. Bank may, without notice to or consent from Borrower and without affecting

			Borrower’s obligations hereunder, sue upon or otherwise collect, extend the time of payment of or compromise or settle for cash, credit or otherwise upon any terms, any of the Receivables or any securities, guaranties, instruments or insurances applicable thereto or release the obligor thereon. Bank is authorized and empowered to accept the return of any Collateral represented by any of the Receivables without notice to or consent by Borrower, all without discharging or in any way affecting Borrower’s liability to Bank. Bank does not, by anything herein or in any assignment or otherwise, assume any of Borrower’s obligations under any contract or agreement assigned to Bank, and Bank shall not be responsible in any way for the performance by Borrower of any of the terms and conditions thereof.
	6.		Cash Collateral Account. All remittances in payment of the Receivables securing the Obligations shall be deposited with Bank (or any other bank designated by Bank) in an account designated as “Provident Bank (name of Borrower), Cash Collateral Account”, if the Bank should desire. Such deliveries and deposits shall be made daily and each deposit shall be accompanied by a report in such form as Bank shall require. All funds held in the Cash Collateral Account may be applied against the Obligations at the discretion of Borrower. In the event any checks or drafts deposited in the Cash Collateral Account are dishonored, Bank is hereby irrevocably authorized to debit any other account of Borrower at Bank in an amount equal to the amount of the checks or drafts dishonored and deposit such sums in the Cash Collateral Account. If thereafter the dishonored check or draft is honored and Bank receives immediately available funds therefore, Bank shall deposit such funds into the account of Borrower which was previously debited. If any checks or drafts deposited in the Cash Collateral Account are drawn on a financial institution located outside of the United States of America, Bank is hereby irrevocably authorized to debit any other account of Borrower at Bank in an amount equal to the United States dollar equivalent of the amount of such checks or drafts and deposit such sums in the Cash Collateral Account. Upon receipt of immediately available funds for any such checks or drafts Bank shall deposit the collected funds into Borrower’s account at Bank which was previously debited. All of the Borrower’s primary operating accounts shall be maintained with the Bank as long as this Agreement is in effect.
	7.		Cancellation of Contracts. Borrower shall notify Bank in writing of any cancellation of a contract having annual revenues in excess of $250,000.
	8.		Government Contracts. In the event any Receivables arise out of contracts with the Government, Borrower shall assign to Bank all Government Contracts with amounts payable of $100,000 or greater and in duration of six (6) months or longer, and execute all other agreements, instruments and documents and shall perform all further acts that Bank may require to ensure compliance with the Assignment of Claims Act with respect to such Government Contracts.
	9.		VDOT Contract Amendments. Borrower shall promptly provide Bank with copies of all amendments to the VDOT Contract.
	10.		VDOT Vendor Liens/Assignments. Upon request, Borrower shall promptly provide Bank with copies of all documents effectuating or related to any VDOT Vendor Liens/Assignments.

O.

Investment Property. If the Collateral includes stocks, bonds or other Investment Property of Borrower, then the covenants in this Paragraph V.O. apply:

	1.		Transfers. All certificates or instruments representing or evidencing such investment property shall be in suitable form for transfer by delivery, shall be in form and substance satisfactory to Bank and shall be delivered to and held by or on behalf of Bank; Bank is hereby authorized, at its option and without any obligation to do so, to transfer to or to register in the name of its nominee(s) all of any part of such Investment Property, and to do so before or after default or the maturity of the Obligations secured hereby, with or without notice to Borrower; Bank shall have the right at any time to exchange certificates or instruments representing or evidencing such Investment Property for certificates or instruments of smaller or larger denominations; Bank shall have control over any securities accounts or security entitlements which constitute Collateral, pursuant to terms acceptable to Bank.

	3.		Attorney-in-Fact. Borrower hereby appoints Bank Borrower’s attorney-in-fact with full authority in the place and stead of Borrower and in the name of Borrower or otherwise, from time to time in Bank’s discretion to take any action and to execute any instrument which Bank may deem necessary or advisable to accomplish the purposes of this Agreement, including, but

not limited to, receiving, endorsing and collecting all checks and other Instruments made payable to Borrower representing any dividend, interest payment, or other distribution in respect of the pledged Investment Property or any part thereof and giving full discharge for the same.

	P.		Government Contract Audits. Promptly after Borrower’s receipt thereof, Borrower shall furnish Bank with notice of any final decision of a contracting officer disallowing costs aggregating more than $100,000 which disallowed costs arise out of any audit of Government Contracts of Borrower.
	Q.		Subsidiaries. If any Borrower creates or acquires a subsidiary containing assets having a value in excess of $100, Borrower shall cause such subsidiary to become a Borrower or Other Obligor hereunder (in a form acceptable to Bank).

VII. REMEDIES

	A.		Specific Rights and Remedies. In addition to all other rights and remedies provided by law and the Loan documents, Bank, on the occurrence of any default, may: (i) accelerate and call due and payable any and all of the Obligations, including all principal, accrued interest and other sums due as of the date of default; (ii) impose the default rate of interest provided in any promissory note evidencing the Loan, with or without acceleration; (iii) file suit against Borrower or against any Other Obligor; (iv) seek specific performance or injunctive relief to enforce performance of the Obligations, whether or not a remedy at law exists or is adequate; (v) exercise any rights of a secured creditor under the Uniform Commercial Code, including the right to take possession of the Collateral without the use of judicial process or hearing of any kind and the right to require Borrower to assemble the Collateral at such place as Bank may specify; (vi) cease making advances or extending credit to Borrower and stop and retract the making of any advance which may have been requested by Borrower; and (vii) reduce the Maximum Line of Credit Amount. Borrower also hereby authorizes Bank, upon a default, but without prior notice to or demand upon Borrower and without prior opportunity of Borrower to be heard, to institute an action for replevin, with or without bond as Bank may elect, to obtain possession of any of the Collateral. In such action for replevin, a copy of this Agreement verified by affidavit of Bank or sworn on behalf of Bank shall constitute evidence of Bank’s right to possession of the Collateral.
	B.		Costs of Collection. Upon the occurrence of any default, Bank shall be entitled to recover from Borrower reasonable attorneys’ fees, plus court costs and other expenses which may be incurred by Bank in the enforcement or attempted enforcement of its rights hereunder, whether against any third party, Borrower, or any Other Obligor. Expenses recoverable from Borrower shall (to the extent not prohibited by law) include costs of collection, including such portion of Bank’s overhead as Bank shall allocate to collection and enforcement of the Obligations in Bank’s sole but reasonable discretion, salaries, out-of-pocket travel, living expenses and the hiring of agents, consultants, accountants, or otherwise. All sums of money thus expended, and all other monies expended by Bank to protect its interest in the Collateral (including insurance, taxes or repairs) shall be repayable by Borrower to Bank on demand, such repayment to be secured as provided in Paragraph III hereof.
	C.		Foreclosure. Upon the occurrence of any default, in addition to other remedies provided under the Uniform Commercial Code, Bank at any time then or thereafter, in its discretion, may lawfully enter any of Borrower’s premises or the premises where the Collateral is located, and with or without judicial process, lawfully remove, under Section 9-609 of the Uniform Commercial Code, the Collateral or records thereof to such place as Bank may deem advisable, or require Borrower to assemble and make any or all such Collateral available at such reasonable place as Bank may direct, and realize upon (by public or private sale or in any other manner) all or any part of the Collateral and, unless the Collateral is perishable or threatens to decline speedily in value, or is of a type customarily sold on a recognized market, Bank shall give Borrower, and other parties entitled to notice, reasonable notice in writing before the sale of the Collateral or any part thereof at public auction or private sale, in one or more sales, at such price or prices, and upon such terms either for cash or credit or future delivery as Bank may elect, and at any such public sale Bank may bid for and become the purchaser of any or all of such Collateral; and/or Bank may foreclose its security interest in the Collateral in any way permitted by law. In connection with any notices to be given pursuant to this Paragraph VII.C., it is agreed in all instances that five (5) business days notice constitutes reasonable notice. Any such notice shall be deemed given when delivered or deposited in the U.S. mail with first class postage. The net proceeds of any such sale or sales and any amounts received in liquidation of the Collateral, less all costs and expenses incurred in connection therewith, including the costs of collection described in Paragraph VII.B above and, at the option of Bank or as required by law, less any prior lien claims, shall be applied against the Obligations in the order that Bank in its sole discretion shall decide, and Borrower or other party entitled thereto shall be entitled to any surplus resulting therefrom. No action taken by Bank pursuant hereto shall affect Borrower’s continuing liability to Bank for any deficiency remaining after any foreclosure. It is mutually agreed that it is commercially reasonable for Bank to disclaim all warranties which arise with respect to the disposition of the Collateral.
	D.		Redemption. The purchaser at any such sale shall thereafter hold the Collateral absolutely free from any claim or right of whatsoever kind including any equity of redemption of Borrower, and such demand, notice or right in equity are hereby expressly waived and released by Borrower.

	E.		Offset. Upon the occurrence of any default, Bank is authorized to charge the sum then due to Bank against any and all monies held by or on deposit with Bank on account of Borrower or its affiliates, and to offset any amounts against any demand or depository accounts which Borrower, or its affiliates, may have with Bank and to enforce such other remedies as may be available at law or in equity, without necessity of election.
	F.		Alternative Remedies. Bank may exercise its rights and remedies hereunder either alternatively or concurrently with its rights under any and all other agreements between Bank and Borrower and shall have the full right to realize upon all available Collateral, collecting on the same or instituting proceedings in connection therewith, until Bank receives payment in full of all amounts owing to Bank under any of its agreements with Borrower, including principal, interest, costs and expenses, and costs of enforcement or attempted enforcement of this or any other agreement among or between Bank and Borrower or any Other Obligors. Bank shall be under no obligation to pursue Bank’s rights against any Other Obligor or any of the collateral of any Other Obligor securing any of the Obligations before pursuing Bank’s rights against Borrower, or the Collateral.

VIII.GENERAL PROVISIONS

	A.		Continuity and Termination. This Agreement shall become effective immediately and remain in effect so long as any of the Obligations are outstanding and unpaid, provided that the security interests hereunder shall continue in full force and effect and are noncancellable by Borrower prior to the termination of this Agreement. This Agreement may be terminated by Borrower upon actual delivery of written notice to Bank of such intention, and payment in full of all then existing Obligations; provided, however, that such notice and payment shall in no way affect, and this Agreement shall remain fully operative with respect to, any Obligations (including contingent Obligations), or commitments which may become Obligations, entered into between Borrower and Bank prior to receipt of such notice or payment, whichever is later.

The Obligations are or shall be evidenced by notes, guaranties, addenda or other documents which are separate agreements and may be negotiated by Bank without releasing Borrower, any Collateral or any Other Obligor. Without limitation of the foregoing, Borrower may have executed and delivered to Bank a Formula Advance Addendum, a Reporting Requirements Addendum and/or a Financial Covenants Addendum which modify and supplement this Agreement and Borrower’s obligations hereunder. This Agreement specifically incorporates by reference all of the language and provisions of such notes, guaranties, addenda or other documents. Borrower consents to any extension of time of payment of any Obligations. If there is more than one Borrower or Other Obligor, the obligation of each of them shall be primary, joint and several.

	G.		Non-Waiver. No indulgence or delay on the part of Bank in exercising any power, privilege or right hereunder or under any other agreement executed by Borrower to Bank in connection herewith shall operate as a waiver thereof. No single or partial exercise of any power, privilege or right shall preclude other or further exercise thereof, or the exercise of any other power, privilege or right.
	H.		Governing Law; Severability. This Agreement shall be construed and governed by the laws of the State of Maryland, If any part of this Agreement shall be adjudged invalid or unenforceable as of any term of court, then such partial invalidity or unenforceability shall not cause the remainder of this Agreement to be or become invalid or unenforceable, and if a provision hereof is held invalid or unenforceable in one or more of its applications, that provision shall remain in effect in all valid or enforceable applications that are severable from the invalid or unenforceable application or applications.
