Subject to the foregoing limitation, the Borrowers (acting through the Agent) may borrow, repay without penalty and re-borrow hereunder from the date hereof until the Termination Date. (b) Subject to the terms and conditions of this Agreement, the Application applicable thereto and the other Loan Documents, the Lender agrees to issue Letters of Credit to QuesTech in an aggregate amount not to exceed Five Hundred Thousand and no/100 Dollars ($500,000.00); provided, however, that the Principal Balance plus the available face amount of outstanding Letters of Credit plus the aggregate amount of drafts drawn under or purporting to be drawn under the Letters of Credit that have been paid by the Lender and for which the Lender has not been reimbursed pursuant hereto shall never exceed the Maximum Amount, with the face amount of Letters of Credit to be replaced by Letters of Credit to be issued on such date being excluded from the calculation of the outstanding face amount of Letters of Credit for such purposes. The expiration date for each Letter of Credit shall be acceptable to the Lender in its sole and absolute discretion. (c) If the Principal Balance, plus the available face amount of outstanding Letters of Credit, plus the aggregate amount of drafts drawn under or purporting to be drawn under the Letters of Credit that have been paid by the Lender and for which the Lender has not been reimbursed pursuant hereto exceeds the Maximum Amount, the Borrowers shall immediately prepay the Loans to the extent necessary to reduce such excess. If after such prepayment the available face amount of outstanding Letters of Credit plus the aggregate amount of drafts drawn under or purporting to be drawn under the Letters of Credit that have been paid by the Lender and for which the Lender has not been reimbursed pursuant hereto exceeds the Maximum Amount, the Borrowers shall immediately deliver to the Lender such additional collateral as the Lender shall deem necessary to adequately secure the Borrowers' obligations with respect to such Letters of Credit and unrepaid drawings. (d) At Closing, all Loans outstanding under the Original Agreement shall become Loans under this Agreement. Except as provided by the preceding sentence, the proceeds of the Loans shall be used for business or commercial purposes, including supporting the issuance by the Lender of Letters of Credit at the request of QuesTech, and for no other purposes. (e) Only the Agent may request Loans. Any request for a Loan must be received by the Lender not later than 1:00 p.m. (Washington, D.C. time) on the date on which the Loan is to be made. Each request must specify the amount of the Loan and, at the option of the Lender, shall be accompanied by a current Borrowing Base Certificate, which may be transmitted by telecopy to the Lender at (703) 506-9553, or such other number as the Lender may designate in written notice to the Agent. If a Borrowing Base Certificate is transmitted by telecopy, the Agent shall maintain the original of such Borrowing Base Certificate as a permanent record for so long as any of the Obligations remain outstanding and shall allow the Lender to inspect such Borrowing Base Certificate and shall provide copies of such original to the Lender upon its request therefor. The proceeds of the Loans will be credited to the Operating Account. Loans may be requested by those individuals designated by the Agent from time to time in written instruments delivered to the Lender; provided, however, that the Borrowers shall remain liable with respect to any Loan disbursed by the Lender in good faith hereunder, even if such a Loan is requested by an individual who has not been so designated. The Borrowers agree to confirm in writing from time to time, when and as requested by the Lender, the purpose for which the proceeds of each Loan were used. (f) Any request for a Letter of Credit to be issued must be made by delivery to the Lender, not later than five (5) Business Days prior to the date of issuance of such requested Letter of Credit, of a properly completed and executed Application. The fee for each Letter of Credit shall be an amount equal to an opening fee of Five Hundred and no/100 Dollars ($500.00) plus a non-refundable commission of two percent (2%) per annum of the undrawn portion of the Letter of Credit, payable in advance upon issuance and thereafter on each anniversary of the date of issuance of such Letter of Credit. The Lender is authorized to advance on behalf of QuesTech as a Loan all sums required to be paid by QuesTech to the Lender in respect of any such Letter of Credit pursuant to the terms of the Application (including the fee set forth above), provided that the Lender may, but shall not be obligated to make such Loans if, after the disbursement thereof, the Principal Balance, plus the available face amount of outstanding Letters of Credit, plus the aggregate amount of drafts drawn under or purporting to be drawn under the Letters of Credit that have been paid by the Lender and for which the Lender has not been reimbursed pursuant hereto would exceed the Maximum Amount. The provisions of the Application are deemed incorporated in this Agreement by this reference and shall be binding upon the Lender and the Borrowers as if fully set forth herein. If a conflict exists between the terms of the Application and any other Loan Document, the terms of the Application shall control with respect to any Letter of Credit issued pursuant to such Application but not as to other matters governed by this Agreement or such Loan Document. 2.2. Interest. Each Loan shall bear interest on the unpaid principal balance thereof from time to time outstanding, for each day from the date such Loan is made until it becomes due, at a per annum rate equal to the Prime Rate plus one-quarter percent (1/4%). Payments of interest on each Loan shall be made on each Interest Payment Date beginning on the Interest Payment Date next succeeding the date of disbursement of such Loan. At the option of the Lender, the Loans shall bear interest at the Default Rate, payable on demand, for each day during any period of Default hereunder. 2.3. Note. The obligation of the Borrowers to repay the Loans, together with interest thereon, shall be evidenced by the Note. The unpaid principal balance of the Note shall be payable on the Termination Date, subject to acceleration, termination or prepayment under the terms of this Agreement. 2.4. Administrative Fee.

If any of the Obligations, including, without limitation, the Loans, shall be evidenced by a demand instrument, the right of the Lender to declare any and all Obligations to be immediately due and payable, as well as the recitation of the above events permitting the Lender to declare all Obligations due and payable, shall not constitute an election by the Lender to waive its right to demand payment under a demand instrument at any time and in any event, as the Lender, in its discretion, may deem appropriate. In addition, the Lender may exercise all of its rights and remedies against the Borrowers and any Collateral. (b) The Lender may foreclose its lien and security interest in the Collateral in any way permitted by law and shall have without limitation, the remedies of a secured party under the UCC. The Lender may notify the account debtors obligated on any of the Collateral to make payments thereon directly to the Lender, take control of the cash and non-cash proceeds of any such Collateral and may enter each Borrower's premises with legal process and without incurring liability to the Borrowers and remove the Collateral to such place or places as the Lender may deem advisable, or the Lender may require the Borrowers to assemble the Collateral and make the Collateral available to the Lender at a convenient place and, with or without having the Collateral at the time or place of sale, the Lender may sell or otherwise dispose of all or any part of the Collateral whether in its then condition or after further preparation or processing, either at public or private sale or at any broker's board, in lots or in bulk, for cash or for credit, at any time or place, in one or more sales, and upon such terms and conditions as the Lender may elect. The Lender shall give not less than five (5) Business Days prior written notice to the Borrowers of the time and place of any sale of the Collateral, which each Borrower hereby agrees constitutes commercially reasonable notice. At any such sale the Lender may be the purchaser. (c) The Borrowers recognize that the Lender may be unable to effect a public sale of all or a part of the Collateral by reason of certain prohibitions contained in the Act and/or the Blue Sky Laws, but may be compelled to resort to one or more private sales to a restricted group of purchasers who will be obliged to agree, among other things, to acquire the Collateral for their own account, for investment and without a view to the distribution or resale thereof. The Borrowers understand that private sales so made may be at prices and on other terms less favorable than if the Collateral were sold at public sales, and agrees that the Lender has no obligation to delay the sale of any of the Collateral for the period of time necessary to permit the issuer of the Collateral (even if the issuer agrees) to register the Collateral for sale under the Act or the Blue Sky Laws. Each Borrower agrees that private sales made under the foregoing circumstances shall be deemed to have been made in a commercially reasonable manner. (d) The proceeds from any sale of the Collateral by the Lender shall first be applied to any costs and expenses in securing possession of the Collateral, and to any expenses in connection with the sale. The net proceeds will be applied toward the payment of the Obligations. Application of the net proceeds as to particular Obligations or as to principal or interest shall be in the Lender's absolute discretion. Any deficiency will be paid to the Lender forthwith upon demand, and any surplus will be paid to the Borrowers or in accordance with law if the Borrowers are not otherwise indebted to the Lender. (e) To the extent that the Obligations are now or hereafter secured by property other than the Collateral described herein or by the guarantee, endorsement or property of any other Person, then the Lender shall have the right to proceed against such other property, guarantee or endorsement upon the occurrence of Event of Default, and the Lender shall have the right in its sole discretion to determine which rights, security, liens, security interests or remedies the Lender shall at any time pursue, relinquish, subordinate, modify or take any other action with respect thereto, without in any way modifying or affecting any of them or any of the Lender's rights hereunder. (f) The Lender is hereby authorized at any time or from time to time, without notice to the Borrowers (any such notice being expressly waived by each Borrower) to set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held, including any certificate of deposit, and other indebtedness at any time owed by the Lender to or for the credit of account of a Borrower against any and all of the Obligations. (g) EACH BORROWER, HAVING KNOWLEDGE THAT IT MAY BE ENTITLED TO NOTICE AND A HEARING PRIOR TO REPOSSESSION OF THE COLLATERAL, HEREBY WAIVES ANY RIGHT THAT IT MAY HAVE UNDER EXISTING OR FUTURE LAW TO NOTICE OF FORECLOSURE AND ANY OTHER ACT DESCRIBED HEREIN, TO ANY HEARING THAT MAY BE HELD RELATING TO FORECLOSURE OR ANY OTHER SUCH ACTS, AND TO ANY NOTICE THAT MAY BE REQUIRED TO BE GIVEN BY THE LENDER PRIOR TO SUCH HEARING. EACH BORROWER HEREBY EXPRESSLY RELEASES THE LENDER AND ITS AGENTS FROM ANY AND ALL LIABILITY RELATING TO SUCH FORECLOSURE AND ANY OTHER ACTS DESCRIBED HEREIN. THE FOREGOING WAIVER SHALL NOT APPLY TO SPECIFIC NOTICE OBLIGATIONS OF THE LENDER SET FORTH IN THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS. (h) The Lender may itself perform or comply, or otherwise cause performance or compliance with the obligations of the Borrowers contained in this Agreement, including, without limitation, the obligations of the Borrowers to defend and insure the Collateral. The expenses of the Lender incurred in connection with such performance or compliance, together with interest thereon at the Default Rate, shall be payable by the Borrowers to the Lender on demand and shall constitute Obligations. SECTION 9. Miscellaneous. 9.1. Collection Costs. The Borrowers shall pay all of the reasonable costs and expenses incurred by the Lender in connection with the enforcement of this Agreement and the other Loan Documents, including, without limitation, reasonable attorneys' fees and expenses. 9.2. Effect on Original Loan Documents, Modification and Waiver. (a) QuesTech and QTSC acknowledge and agree that their respective obligations under the Original Loan Documents remain valid and enforceable obligations and that the execution and delivery of this Agreement and the other Loan Documents executed in connection herewith shall not be construed as a novation of any of the Original Loan Documents. If any provision of this Agreement or any of the other Loan Documents is avoided or found to be unenforceable, the corresponding provision of the Original Loan Documents shall be automatically reinstated. QuesTech and QTSC further acknowledges and agrees that, as of the date hereof, they have no offsets or defenses against the payment of any of their obligations under the Original Loan Documents. As a specific inducement to the Lender without which QuesTech and QTSC acknowledge the Lender would not enter into this Agreement and the other Loan Documents, QuesTech and QTSC hereby waive any and all claims that they may have against the Lender, as of the date hereof, arising out of or relating to the Original Loan Documents, whether sounding in tort or any other basis. (b) The terms and conditions pursuant to which the Lender is making the Loans available to the Borrowers and the other terms and conditions generally related to the relationship between the Borrowers and the Lender are completely restated in this Agreement and the other Loan Documents executed in connection herewith. Accordingly, the Original Loan Documents are superseded by this Agreement and the other Loan Documents executed in connection herewith except as provided in the immediately following sentence. Notwithstanding the foregoing, the Original Loan Documents shall survive and remain in effect to the extent they grant collateral to the Lender as security for the obligations of any of the Borrowers outstanding on the date hereof or are otherwise necessary to support the grant of such collateral. In the event of a conflict between the terms of the Original Loan Documents and the terms of this Agreement and the other Loan Documents executed in connection herewith, the terms of this Agreement and the other Loan Documents executed in connection herewith shall control. (c) This Agreement, the other Loan Documents executed in connection herewith and the Original Loan Documents [subject, however, to the limitations set forth in Sections 9.2(a) and (b)] contain the entire agreement between the parties. (d) No modification or waiver of any provision of any of these documents and no consent by the Lender to any departure therefrom by the Borrowers shall be effective unless such modification or waiver shall be in writing and signed by an officer of the Lender with a title of assistant vice president or any higher office, and the same shall then be effective only for the period and on the conditions and for the specific instances and purposes specified in such writing. (e) No notice to or demand on the Borrowers in any case shall entitle the Borrowers to any other or further notice or demand in similar or other circumstances. (f) No failure or delay by the Lender in exercising any right, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided are cumulative and not exclusive of any rights or remedies otherwise provided by law. 9.3. Notices. All notices, requests, demands or other communications required or permitted by or in connection with this Agreement or any other Loan Document, without implying the obligation to provide any such notice, request, demand or other communication, shall be in writing addressed to the appropriate address set forth below or to such other address as may be hereafter specified by written notice by the Lender or the Borrowers, as applicable, forwarded in like manner.

Use of Defined Terms. All terms defined in this Agreement shall have the defined meanings when used in certificates, reports or other documents made or delivered pursuant to this Agreement, unless the context shall otherwise require. 9.9. Successors and Assigns. (a) This Agreement shall inure to the benefit of and bind the respective parties hereto and their successors and assigns; provided, however, that no Borrower may assign its rights hereunder without the prior written consent of the Lender. (b) At any time and from time to time, the Lender may grant to one or more Banks participating interests in the Lender's commitment to make Loans hereunder or in any or all of the Loans or the Note. In the event of any such grant by the Lender of a participating interest to a Bank, whether or not upon notice to the Borrowers, the Lender shall remain responsible for the performance of its obligations hereunder, and the Lender shall continue to deal solely and directly with the Borrowers in connection with the Lender's rights and obligations under this Agreement. Any agreement pursuant to which the Lender may grant such a participation interest shall provide that the Lender shall retain the sole right and responsibility to enforce the obligations of the Borrowers hereunder including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement; provided that such participation agreement may provide that the Lender will not agree to any modification, amendment or waiver of this Agreement which would have the effect increasing or decreasing the Maximum Amount, extending the Termination Date, subjecting the Lender to any additional obligation, reducing the principal of or rate of interest on any Loan, or postponing the date fixed for any payment of principal of or interest on any Loan or fees hereunder or under the Note without the consent of such Bank. An assignment or other transfer which is not permitted by subsection (c) or (d) below shall be given effect for purposes of this Agreement only to the extent of a participating interest granted in accordance with this subsection (b). (c) At any time, the Lender may assign to one or more Banks all, or a proportionate part of all, of the Lender's rights and obligations under this Agreement and the Note, and such Bank shall assume such rights and obligations, pursuant to an instrument executed by such Bank and the Lender, with (and subject to) the consent of the Borrowers; provided that if such Bank is an affiliate of the Lender, the Borrowers' consent shall not be required. Upon execution and delivery of such an instrument and payment by such Bank to the Lender of an amount equal to the purchase price agreed between the Lender and such Bank, such Bank shall become a party to this Agreement and shall have all the rights and obligations of the Lender to the extent of such Bank's commitment to make Loans as set forth in such Bank's instrument of assumption, and the Lender shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required. Upon the consummation of any assignment pursuant to this subsection (c), the Lender and the Borrowers shall make appropriate arrangements so that, if required, a new Note is issued to the Bank. If the Bank is not incorporated under the laws of the United States of America or a state thereof, it shall, prior to the first date on which interest or fees are payable hereunder for its account deliver to the Borrowers certification as to exemption from deduction or withholding of any United States federal income taxes. (d) The Lender may at any time assign all or any portion of its rights under this Agreement and the Note to a Federal Reserve Bank. No such assignment shall release the Lender from its obligations hereunder. (e) The Lender may furnish any information concerning the Borrowers in its possession from time to time to any Bank which is or may become a participant or assignee under this Section 9.9 and may furnish such information in response to credit inquiries consistent with general banking practice. 9.10. Accounting Terms. All accounting terms used herein which are not otherwise expressly defined in this Agreement shall have the meanings respectively given to them in accordance with GAAP in effect on the date of this Agreement. Except as otherwise provided herein, all financial computations made pursuant to this Agreement shall be made in accordance with GAAP and all balance sheets and other financial statements shall be prepared in accordance with GAAP. Except as otherwise provided herein, whenever reference is made in any provision of this Agreement to a balance sheet or other financial statement or the information depicted therein for performing a financial computation, such terms shall mean the most recent consolidated balance sheet or other financial statement received by the Lender pursuant to the terms hereof. 9.11. Consent to Jurisdiction. Each Borrower irrevocably submits to the jurisdiction of any Virginia State court sitting in the County of Fairfax or the United States District Court for the Eastern District of Virginia, sitting in Alexandria, Virginia over any suit, action or proceeding arising out of or relating to this Agreement. To the fullest extent it may effectively do so under applicable law, each Borrower irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. 9.12. Enforcement of Judgments. Each Borrower agrees, to the fullest extent it may effectively do so under applicable law, that a judgment in any suit, action or proceeding of the nature referred to in Section 9.11 brought in any such court shall be conclusive and binding upon such Borrower and may be enforced in the courts of the United States of America or the Commonwealth of Virginia (or any other courts to the jurisdiction of which such Borrower is or may be subject) by a suit upon such judgment. 9.13. Waiver of Jury Trial. [INTENTIONALLY DELETED] 9.14. Service of Process. Each Borrower consents to process being served in any suit, action or proceeding of the nature referred to in Section 9.11 by mailing a copy thereof by registered or certified mail postage prepaid, return receipt requested, to the Borrowers' address specified in or designated pursuant to Section 9.3. Each Borrower agrees that such service (i) shall be deemed in every respect effective service of process upon such 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 such Borrower. 9.15. No Limitation on Service or Suit. Nothing in this Section 9 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 Borrowers in the courts of any jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction. 9.16. Indemnification. At all times prior to and after the consummation of the transactions contemplated by this Agreement, the Borrowers will indemnify and hold each Indemnitee harmless from and against all losses, damages, claims, fines, costs and expenses (including, without limitation, reasonable attorneys' fees, costs and expenses) incurred by any such Indemnitee, whether direct or indirect, as a result of or arising from or relating to any Proceedings by any Person, whether threatened or initiated, asserting a claim for any legal or equitable remedy against any Indemnitee arising from or in connection with this Agreement, the Note or any of the other Loan Documents, and any of the transactions contemplated herein or therein, except to the extent such losses, damages, claims, fines, costs or expenses are due to the willful misconduct or gross negligence of the Lender; provided that in connection with such indemnification obligations, the Borrowers shall not be liable for any settlement effected by any Indemnitee without the Borrowers' prior consent (which the Borrowers shall not unreasonably withhold, delay or condition) and the Borrowers shall have the right to participate at their sole cost and expense in the defense of any proceeding for which such indemnification may be sought. In the event of any Proceeding, the Lender shall promptly and as soon as is practicable notify the Borrowers of the existence of such Proceeding, provided that the Lender's failure to do so shall not preclude any Indemnitee from seeking indemnification hereunder. At the request of the Lender, the Borrowers will indemnify any Person to whom the Lender transfers or sells all or any portion of its interest in the Loans or participations therein on the terms set forth above. The obligations of the Borrowers under this Section 9.16 shall survive the termination of this Agreement and payment of the Obligations. 9.17. No Partnership, Joint Venture or Agency. Neither this Agreement nor any of the Loan Documents shall in any respect be interpreted, deemed or construed as making the Lender a partner or joint venturer with the Borrowers, nor shall they be interpreted, deemed or construed as making the Lender the agent of representative of the Borrowers, and each Borrower agrees not to make any contrary assertion, contention, claim or counterclaim in any action, suit or other legal proceeding involving the Lender. 9.18. Interpretation. (a) This Agreement and the rights and obligations of the parties hereunder shall be construed and interpreted in accordance with the laws of the Commonwealth of Virginia, excluding principles of conflict of laws. (b) The Lender hereby acknowledges and agrees that this Agreement shall be subject to and interpreted in accordance with all applicable legal, regulatory and contractual obligations of the Borrowers with respect to the security, privacy or nondisclosure of certain information regarding the business of the Borrowers. By way of example and not limitation, the Lender acknowledges and agrees that the Borrowers may be prohibited from (i) disclosing the location of certain information with respect to certain Accounts Receivable, (ii) providing access to certain books and records and (iii) permitting the Lender to inspect certain Collateral. The Lender hereby agrees that the compliance of the Borrowers with such legal, regulatory and contractual obligations shall not give rise to an Event of Default hereunder, even if such compliance conflicts with the representations, warranties, covenants, agreements and conditions set forth herein. 9.19 Joint and Several Obligations. The Borrowers are jointly and severally liable for all Obligations. IN WITNESS WHEREOF, the Borrowers and the Lender have caused this Agreement to be signed by their duly authorized representatives all as of the day and year first above written, with the specific intention that this Agreement constitute a document under seal.
