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.

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;

     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

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

     ARTICLE 4. SECURITY.

4.1 Grant of Security Interest. As security for (i) the payment of the Loan, and any other extensions of credit, loans, letters of credit or other financial accommodations now or hereafter made by the Lender for the benefit of the Borrower, and (ii) the performance of the Borrower’s obligations under or in connection with any interest rate swap agreement as defined in 11 U.S.C. ‘101 by and between the Borrower and the Lender or any Affiliate of the Lender (whether absolute or contingent and whether now or hereafter becoming due or owing), and (iii) any other liability or 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, other applicable law and this Agreement. The Borrower covenants and agrees to execute and deliver, 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 any and all acts as are necessary in the opinion of the Lender to perfect, maintain and protect the security interest hereby granted. The Borrower shall not dispose of the Collateral, or any part thereof, other than in the ordinary course of its business or as otherwise may be permitted by this Agreement.

4.2 Covenants Regarding Inventory and Equipment. With regard to Collateral that constitutes Inventory or Equipment, the Borrower further covenants as follows:

     a. The Borrower shall not permit any of the Equipment to become a fixture to any real estate unless subordination agreements satisfactory to the Lender are obtained by any owner or mortgagee of such real estate.

     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.

4.3 Certain Rights of the Lender. The Lender shall have the right, but not the obligation, (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 rise to Accounts. Such payments and the costs of curing such defaults shall constitute Advances under the Revolving Note and shall be secured pursuant to this Agreement, irrespective of whether the Borrower would then be entitled to such Advances under this Agreement.

4.4 Financing Statements; Possession of Collateral by Lender; Control. At the 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 otherwise, in form satisfactory to the Lender, and Borrower will pay the cost of filing the same in 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

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

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

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.

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 and to prevent others from using such Intellectual Property without consent.

5.13 Disclosure. No representation or warranty of Borrower contained in this Agreement or any of the Loan Documents and no written statement of fact furnished or to be furnished by Borrower to the Lender pursuant to this Agreement or any of the Loan Documents, when viewed together, contains or will contain any untrue statement of a fact material to the financial condition of Borrower, or omits or will omit to state any material fact necessary in order to make the statements contained herein or therein, or furnished herewith or therewith, not misleading.

     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 contracting or subcontracting with the Government; or

     l. any material default by Borrower occurs under the terms of any Government Contract or any breach in Borrower’s performance obligations occurs under any Government Contract; or

     m. any Government Contract is terminated for default; or

     n. any loss, theft, damage or destruction of any material portion of the Collateral for which there is either no insurance coverage or for which, in the opinion of the Lender, there is insufficient insurance coverage; or

     o. a twenty five percent (25%) or greater voting control interest in Borrower is directly or indirectly sold, assigned, transferred, encumbered or otherwise conveyed (whether in a single or multiple transfers) without the prior written consent of the Lender; or

     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 of the Code) or breach of fiduciary responsibility shall occur which may subject the Borrower or any of its subsidiaries or any ERISA Affiliate to any liability under Section 406, 409, 502(i), or 502(l) of ERISA or Section 4975 of the Code, or under any agreement or other instrument pursuant to which the Borrower or any of its subsidiaries or any ERISA Affiliate has agreed or is required to indemnify any Person against any such liability; or

     q. Borrower or any other Person standing as a Guarantor for the Loan or providing security for the Loan shall fail to observe or perform any other term, covenant or agreement contained in this Agreement or in any other Loan Document or in any other agreement (including, 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.

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,

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;

     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

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

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.

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.

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.

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

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.
