1.2. Revolving Credit Facility.

(a) Advances and Letters of Credit. Subject to and upon the provisions of this Agreement and relying upon the representations and warranties herein set forth, the Lender

agrees at any time and from time to time to make Advances to the Borrowers and issue Letters of Credit for the account of the Borrowers from the date hereof until the earlier of the Revolving Credit Expiration Date or the date on which this Revolving Credit Facility is terminated pursuant to Section 7 hereof, in an aggregate principal amount at any time outstanding not to exceed the Revolving Credit Amount; provided however, that in no event shall the total Letter of Credit Exposure exceed Two Million Dollars ($2,000,000) at any one time.

In no event shall the Lender be obligated to make an Advance or issue a Letter of Credit hereunder if a Default shall have occurred and be continuing. Unless sooner terminated pursuant to other provisions of this Agreement, this Revolving Credit Facility and the obligation of the Lender to make Advances and issue Letters of Credit hereunder shall automatically terminate on the Revolving Credit Expiration Date without further action by, or notice of any kind from, the Lender. Within the limitations set forth herein and subject to the provisions of this Agreement, the Borrowers may borrow, repay and reborrow under this Revolving Credit Facility. The fact that there may be no Advances or Letters of Credit outstanding at any particular time shall not affect the continuing validity of this Agreement.

(b) Use of Proceeds of Advances. Each Advance shall be advanced by the Lender not later than the Business Day following the day (which shall be a Business Day) of the Borrowers’ request therefor. The proceeds of each Advance may be deposited by the Lender in the Borrowers’ demand deposit account with the Lender. The proceeds of the Advances shall be used solely for working capital, for acquisitions permitted by the terms of this Agreement, and for other lawful purposes.

(c) Liability of Lender. Lender shall in no event be responsible or liable to any person other than Borrowers for the disbursement of or failure to disburse Advances or any part thereof, and no other party shall have any right or claim against Lender under this Agreement or the other Financing Documents.

(d) Interest on Advances; Repayment of Advances. Except for any period during which an Event of Default shall have occurred and be continuing, the Borrowers shall pay interest (calculated on a daily basis) on the unpaid principal balance of the Advances until maturity (whether by acceleration, extension or otherwise) at a per annum rate of interest equal at all times to the LIBOR-Based Rate in effect from time to time.

After maturity, or during any period in which an Event of Default exists and remains continuing, the unpaid principal balance of the Advances shall bear interest at a rate equal to the Default Rate.

Notwithstanding any other provision of this Agreement, if the Lender determines in good faith (which determination shall be conclusive) (i) that any applicable law, rule, or regulation, or any change in the interpretation of any such law, rule, or regulation shall make it unlawful or impossible for the Lender to charge or collect interest at the LIBOR-Based Rate, or (ii) that quotations of interest rates for the relevant deposits referred to in the definition of the LIBOR-Based Rate are not being provided in the relevant amounts or for the relevant maturities, then upon notice from the Lender to the Borrowers, the entire outstanding principal balance of the Revolving Credit Facility shall bear interest at the Prime-Based Rate.

Until the maturity of the Revolving Credit Facility, all accrued and unpaid interest on all Advances shall be paid monthly on the first day of each month (each, an “Interest Payment Date”).

If not sooner paid, the entire outstanding principal balance of the Advances, together with all accrued and unpaid interest thereon, shall be due and payable on the Revolving Credit Expiration Date.

(e) Unused Commitment Fee. During the period from the date hereof until the earlier of the Revolving Credit Expiration Date or the date on which the Revolving Credit Facility is terminated pursuant to the provisions hereof, the Borrowers shall pay to the Lender an availability fee in a per annum amount equal to the Unused Commitment Fee Percentage times the average daily unused portion of the Revolving Credit Amount. Such availability fee shall commence to accrue on the date hereof and shall be due and payable by the Borrowers quarterly, in arrears, commencing on March 31, 2006 and on the last Business Day of each third month thereafter, and on the earlier of the Revolving Credit Expiration Date or on the date on which the Revolving Credit Facility is terminated pursuant to Section 7 hereof.

(f) Note; Revolving Credit Account. The Borrowers’ obligation to pay the Advances with interest shall be evidenced by the Note. The Lender will maintain the Revolving Credit Account with respect to advances, repayments and prepayments of Advances, the accrual and payment of interest on Advances and all other amounts and charges owing to the Lender in connection with Advances. Except for demonstrable error, the Revolving Credit Account shall be conclusive as to all amounts owing by the Borrowers to the Lender in connection with and on account of Advances.

(g) Notwithstanding anything contained herein to the contrary, so long as the Borrowers opt to use the Lender’s “AutoBorrow” program and have executed and delivered to the Lender an AutoBorrow Service Agreement (which AutoBorrow Service Agreement remains in full force and effect), all Advances to be made hereunder shall be made in accordance with, and all interest accrued on such Advances and all repayments of such Advances shall be payable at the times and in the manner provided for in, the AutoBorrow Service Agreement. To the extent that any of the provisions of Section 1.2(a) through 1.2(g) hereof are inconsistent with provisions of the AutoBorrow Service Agreement, the provisions of the AutoBorrow Service Agreement shall govern. Any Advances made to the Borrowers under the AutoBorrow Service Agreement shall nonetheless be deemed to be an Advance hereunder, subject to all other terms hereof.

(h) Voluntary Prepayments; Voluntary Termination. The Borrowers may prepay any Advance in whole or in part, from time to time without premium or penalty. Any permitted prepayment need not be accompanied by payment of interest on the amount prepaid except that any prepayment of Advances which constitutes a final payment of all Advances shall be accompanied by payment of all interest thereon accrued through the date of prepayment.

(i) Terms of Letters of Credit. Each Letter of Credit shall (i) be a commercial Letter of Credit or a standby Letter of Credit, (ii) be opened pursuant to a Letter of Credit Agreement duly executed and delivered to the Lender by the Borrowers prior to the issuance of such Letter of Credit, (iii) expire not later than six (6) months after the Revolving Credit Expiration Date (unless such are secured by cash or cash-equivalent collateral satisfactory to the Lender in the Lender’s sole discretion) provided, however, that if the Revolving Credit Facility is not renewed or extended, the Borrower shall provide cash security for all outstanding Letters of Credit scheduled to expire after the Revolving Credit Expiration date, not later than fifteen (15) days prior to the Revolving Credit Expiration Date, (iv) be in an amount not less than $10,000, (v) be issued in the ordinary course of the Borrowers’ business, and (vi) be issued in accordance with the Lender’s then current practices relating to the issuance of letters of credit. All powers, right, remedies and provisions set forth in any Letter of Credit Agreement shall be in addition to those set forth herein. In the event of any conflict between the provisions of this Agreement and the provisions of any Letter of Credit Agreement, the provisions of this Agreement shall prevail and control unless expressly provided otherwise herein or in the Letter of Credit Agreement.

(j) Procedures for Letters of Credit. The Borrowers shall give the Lender written notice of its request for a Letter of Credit at least three (3) Business Days prior to the date on which the Letter of Credit is to be opened by delivering to the Lender a duly executed Letter of Credit Agreement in form and content acceptable to the Lender setting forth (i) the face amount of the Letter of Credit, (ii) the name and address of the beneficiary of the Letter of Credit, (iii) whether the Letter of Credit is irrevocable or revocable, (iv) whether the Letter of Credit requested is a standby or commercial Letter of Credit, (v) the date the Letter of Credit is to be opened and the date the Letter of Credit is to expire, (vi) the purpose of the Letter of Credit, (vii) the terms and conditions for any draws under the Letter of Credit, and (viii) such other information as the Lender may reasonably deem to be necessary or desirable.

(k) Letter of Credit Fees. With respect to each Letter of Credit issued hereunder, the Borrowers shall pay to the Lender a letter of credit fee (the “Letter of Credit Fee”) in an amount per annum set forth in the table attached hereto as Attachment I, payable quarterly in advance, plus the Lender’s then standard fee for the issuance, negotiation, processing and administration of letters of credit of the same type as the Letter of Credit. The amount of the Letter of Credit Fee payable per annum with respect to any Letter of Credit shall be a percentage of the face amount of such Letter of Credit, calculated on the basis of the table included as Attachment I hereto, based upon the Borrowers’ ratio of Total Funded Debt to EBITDA as of the end of the calendar quarter immediately preceding the date of calculation.

(l) Agreement to Pay Letter of Credit Obligations. The Borrowers shall pay to the Lender the Letter of Credit Obligations when due; provided, however, that (a) so long as the Borrowers have availability under the Revolving Credit Facility, the Lender may, and is hereby authorized to, make Advances to itself to pay when due any or all Letter of Credit Obligations incurred in connection with Letters of Credit. The Lender may maintain on its books a letter of credit account (the “Letter of Credit Account”) with respect to the Letter of Credit Obligations paid and payable from time to time hereunder. Except for demonstrable error, the Letter of Credit Account shall be conclusive as to all amounts owing by the Borrowers to the

Lender in connection with and on account of the Letter of Credit Obligations. From the date due until paid in full, all Letter of Credit Obligations shall bear interest at the rate then applicable to Advances.

(m) Agreement to Pay Absolute. The obligation of the Borrowers to pay Letter of Credit Obligations set forth above shall be absolute and unconditional and irrespective of (i) any lack of validity or enforceability of any Letter of Credit, (ii) the existence of any claim, setoff, defense or other right which the Borrowers may at any time have against the beneficiary under any Letter of Credit or the Lender, (iii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue provided that payment by the Lender under such Letter of Credit against presentation of such draft shall not have constituted gross negligence or willful misconduct, and (v) any other events or circumstances whatsoever, whether or not similar to any of the foregoing provided that the payment by the Lender under the Letter of Credit shall not have constituted gross negligence or willful misconduct of the Lender.

(n) Commitment Fee. In consideration for the agreements of the Lender as set forth herein, the Borrowers agree to pay to the Lender at closing the balance remaining of its commitment fee of twenty-five (25) basis points times the Revolving Credit Amount, which fee shall be deemed earned upon its receipt by the Lender.

Other than calculations with respect to the Prime Rate (which shall be computed on the basis of actual days elapsed in a 365/366 day year), all interest and fees payable under the provisions of this Agreement or the Note shall be computed on the basis of actual number of days elapsed over a year of 360 days.

Such 15-day period shall not be construed in any way to extend the due date of any such payment. Late charges are imposed for the purpose of defraying the Lender’s expenses incident to the handling of delinquent payments, and are in addition to, and not in lieu of, the exercise by the Lender of any rights and remedies hereunder or under applicable laws and any fees and expenses of any agents or attorneys which the Lender may employ upon the occurrence of an Event of Default.

All payments of principal, interest, fees or other amounts to be made by the Borrowers under the provisions of

this Agreement or the Note shall be paid without set-off or counterclaim to the Lender at the Lender’s office at 1101 Wooton Parkway, 4^th Floor, Rockville, Maryland 20852, or to such other place as the Lender shall direct in writing, in lawful money of the United States of America in immediately available funds.

The Borrowers shall pay all costs of, and incidental to, the filing, recording or registration of any such document as well as any recordation, transfer or other tax required to be paid in connection with any such filing, recordation or registration. The Borrowers hereby covenant to save harmless and indemnify the Lender from and against any liability resulting from the failure to pay any required documentary stamps, recordation and transfer taxes and recording costs incurred by the Lender in connection with this Agreement or the Collateral which covenant shall survive the termination of this Agreement and the payment of all other Obligations. The Borrowers agree that a carbon, photographic, photostatic or other reproduction of this Agreement or of a financing statement signed by the Borrowers in connection with this Agreement shall be sufficient as a financing statement. If, in the reasonable opinion of the Lender, any Equipment is or may become a part of any real estate owned or leased by the Borrowers, the Borrowers will, upon the request of the Lender, furnish to the Lender in form and content satisfactory to the Lender, a landlord’s waiver by the record owner of such real estate and a mortgagee’s waiver by any person who has a security interest or lien on such real estate which is or may be superior to the security interest and lien of the Lender on such Equipment.

4.14. Collections.

(a) At any time while an Event of Default shall occur and be continuing, the Borrowers shall notify and direct all account debtors promptly following written request by the Lender to make all payments on or in respect of Accounts and/or the sale or lease of Inventory (other than electronic funds transfers) directly to an account in the name of the Borrowers to be maintained at the Lender (the “Collection Account”). So long as no Event of Default has occurred, the Borrowers may continue to permit electronic payments to be made to the Borrowers’ operating accounts (collectively, the “Operating Accounts”).

(b) At any time while an Event of Default shall be continuing, the Lender may (1) terminate the authority of the Borrowers to receive electronic payments into the Operating Accounts, whereupon all account debtors shall be directed to remit all payments directly to the Collection Account, and (2) terminate the authority of the Borrowers to withdraw funds from the Collection Account whereupon (i) the Collection Account will automatically convert into an account over which the Lender has exclusive dominion, control and power of access and withdrawal, and, for that purpose, the Lender is hereby authorized to take all appropriate actions to block the Borrowers’ access to the Collection Account, including without limiting the generality of the foregoing, denying electronic access and returning unpaid any checks, drafts or other instruments theretofore or thereafter issued by the Borrowers and drawn upon the Collection Account, all without any liability whatsoever on the part of the Lender to the Borrowers or to any other person for having done so, (ii) any cash, checks, drafts or other remittances on or in respect of Accounts and/or the sale or lease of Inventory received by the Borrowers and held in trust for the Lender as above provided shall be immediately delivered to the Lender for deposit to the Collection Account in precisely the form received, except for the addition thereto of the endorsement of the Borrowers where required for collection of any such checks, drafts or other remittances which endorsement the Borrowers agree to make and with respect to such checks, drafts and other remittances the Borrowers waives notice of presentment, protest and non-payment and (iii) the Lender shall have the right at any time and from time to time to apply funds held by it in the Collection Account to the payment of all or any part of the Obligations, whether matured or unmatured, in such order and manner as the Lender may determine in its sole discretion.

4.15. Assignment of Payments Under Certain Government Contracts and Government Accounts. At any time while an Event of Default has occurred and is continuing, and thereafter upon the creation of any Government Contract, if so requested by the Lender, the Borrowers shall execute and deliver to the Lender specific assignments of payments due or to become due with respect to any Government Contracts. The Lender may, in its sole and absolute discretion, from time to time exclude from this requirement contracts that (a) provide for payments to Borrowers of less than $500,000, or (b) are less than six (6) months in duration; provided, however that any such exclusion, if granted, shall not release the Borrowers from the obligation to provide such assignments in the future, at the Lender’s discretion. 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, but rather the Lender’s security interest, as stated above, shall extend to payments under any and all Government Contracts and proceeds thereof, now or hereafter owned or acquired by Borrowers. Borrowers acknowledge that the Lender will be

irreparably harmed if Borrowers 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 Borrowers agree that the Lender shall be entitled, in addition to all other remedies allowed by law or under this Agreement, to injunctive or other equitable relief to compel Borrowers’ compliance with the provisions of this Agreement requiring the Borrowers to assign payments due or to become due under any Government Contract.

4.17. Primary Operating Accounts. The Borrowers hereby agree to maintain the primary operating account for the business operations of the Borrowers with the Lender. The Borrowers recognize and agree that the pricing for the Revolving Credit Facility set forth herein is based on the assumption that the Borrowers will so maintain their primary operating accounts with the Lender, and that, in the event that the Borrowers fail to do so, the Lender may, among other things, adjust the applicable interest rate or fees in order to maintain its required rate of return.

Upon the occurrence and during the continuation of any Event of Default, then in each and every case, the Lender shall be entitled to exercise in any jurisdiction in which enforcement thereof is sought, the following rights and remedies, in addition to the rights and remedies available to the Lender under the other provisions of this Agreement and the other Financing Documents, the rights and remedies of a secured party under the Uniform Commercial Code and all other rights and remedies available to the Lender under applicable law, all such rights and remedies being cumulative and enforceable alternatively, successively or concurrently:

(a) The Lender shall have the right to take possession of the Collateral, and for that purpose, so far as the Borrowers may give authority therefor or to the extent permitted under applicable laws, to enter upon any premises on which the Collateral or any part thereof may be situated and remove therefrom all or any of the Collateral without any liability for suit, action or other proceeding. THE BORROWERS HEREBY WAIVE ANY AND ALL RIGHTS TO PRIOR NOTICE AND TO JUDICIAL HEARING WITH RESPECT TO REPOSSESSION OF COLLATERAL, and require the Borrowers, at the Borrowers’ expense, to assemble and deliver all or any of the Collateral to such place or places as the Lender may designate.

(b) The Lender shall have the right to operate, manage and control all or any of the Collateral (including use of the Collateral and any other property or assets of the Borrowers in order to continue or complete performance of the Borrowers’ obligations under any contracts of Borrowers), or permit the Collateral or any portion thereof to remain idle or store the same, and collect all rents and revenues therefrom and sell, lease or otherwise dispose of any or all of the Collateral upon such terms and under such conditions as the Lender, in its sole discretion, may determine, and purchase or acquire any of the Collateral at any such sale or other disposition, all to the extent permitted by applicable law.

(c) The Lender shall have the right, and the Borrowers hereby irrevocably designate and appoint the Lender and its designees as the attorney-in-fact of the Borrowers, with power of substitution and with power and authority in the Borrowers’ name, the Lender’s name or otherwise and for the use and benefit of the Lender (i) to notify persons obligated to make payments or other remittances on or with respect to the Collateral to make such payments and other remittances directly to the Lender, (ii) to demand, collect, sue for, take control of, compromise, settle, change the terms of, release, exchange, substitute, extend, renew or otherwise deal with, the Collateral or any person obligated on or under the Collateral in any manner as the Lender may deem advisable, (iii) to remove from any place of business of the Borrowers copies of (or, if deemed by the Lender to be reasonably necessary, originals of) all records in respect of the Collateral and, at the cost and expense of the Borrowers, to make use of any place of business of the Borrowers as may be necessary or desirable to administer, control, collect, sell or otherwise dispose of the Collateral, (iv) to receive and endorse the Borrowers’ name on any checks, drafts, money orders or other instruments of payment relating to any of the Collateral, (v) to sign any proofs of claim or loss, (vi) to commence, prosecute or defend any action, suit or proceeding relating to the Collateral or the collection, enforcement or realization upon the Collateral, (vii) to adjust and compromise any claims under insurance policies, and (viii) to use, sell, assign, transfer, pledge, make any agreement with respect to or otherwise deal with any or all of the Collateral and to do all other acts and things necessary to carry out this Agreement as though the Lender were absolute owner of the Collateral.

Neither the Lender nor any of its designees shall be liable for any acts of commission or omission, nor for any error of judgment or mistake of fact or law other than acts of actual fraud, willful misconduct or gross negligence. The provisions of this subsection shall not (x) be construed as requiring or obligating the Lender or any designee to take any action authorized hereunder and any action taken or any action not taken hereunder shall not give rise to any liability on the part of the Lender or its designees or to any defense, claim, counterclaim or offset in favor of the

Borrowers, (y) be construed to mean the Lender has assumed any of the obligations of the Borrowers under any instrument or agreement as the Lender shall not be responsible in any way for the performance of the Borrowers of any of the provisions thereof, and (z) relieve the Borrowers of any of its obligations hereunder or in any way limit the exercise by the Lender of any other or further rights it may have hereunder, under the other Financing Documents, by law or otherwise.

The Borrowers shall on demand from time to time pay such interest to the Lender and the same shall be a part of the Obligations hereunder.

7.3. Liens, Set-Off.

In addition to, and without limitation of, any rights of the Lender under applicable laws, if any Event of Default occurs and is continuing, the Lender may at any time and from time to time thereafter during the continuance of such Event of Default, without notice to the Borrowers, set-off, hold, segregate, appropriate and apply at any time and from time to time thereafter all such indebtedness, deposits, credits, balances (whether provisional or final and whether or not collected or available), monies, securities and other property toward the payment of all or any part of the Obligations in such order and manner as the Lender in its sole discretion may determine and whether or not the Obligations or any part thereof shall then be due or demand for payment thereof made by the Lender.

The Borrowers agree to pay to the Lender on demand (a) all Enforcement Costs paid, incurred or advanced by or on behalf of the Lender including, without limitation, reasonable attorneys’ fees, costs and expenses, and (b) interest on such Enforcement Costs from the date payment for the same is demanded until paid in full at a per annum rate of interest equal at all times to the Default Rate. All Enforcement Costs, with interest as above provided, shall be a part of the Obligations hereunder.

If any Event of Default shall occur and be continuing, and the Lender shall elect to terminate the Revolving Credit Facility, the Borrowers at any time and from time to time during the continuance of such Event of Default shall upon demand of the Lender deliver to the Lender cash or U.S. Treasury Bills with maturities of not more than thirty (30) days in an amount equal to the amount of issued or pending Letters of Credit as of such time. The Lender may also deposit to the Collateral Account (defined below) any cash, monies or funds received by the Lender from the collection of the Obligations or the sale or other

disposition of the Collateral which the Lender, in its discretion, designates as being held against issued or pending Letters of Credit as of such time. Such cash, monies, funds or U.S. Treasury Bills shall be held by the Lender in an account (the “Collateral Account”) and invested or reinvested (as the case may be) in U.S. Treasury Bills with maturities of no more than thirty (30) days from the date of investment. The Lender shall have the sole power of access and withdrawal from the Collateral Account. As collateral and security for the payment of the Obligations, the Borrowers hereby assigns and pledges to the Lender, and grants to the Lender a security interest in and to, all cash, monies, funds, U.S. Treasury Bills and other securities and instruments at any time and from time to time held by the Lender in the Collateral Account and any interest, income, earnings and proceeds thereof, all of which shall be a part of the Collateral hereunder. If any Event of Default shall occur and be continuing, the Lender is irrevocably authorized to make such withdrawals from the Collateral Account at any time and from time to time and apply the same to any of the Obligations (including, without limitation, Letter of Credit Obligations) in such order and manner as the Lender in its sole discretion may determine. After all Obligations have been indefeasibly paid in full and there are no Letters of Credit outstanding or any commitment on the part of the Lender to open and issue Letters of Credit, any cash, monies, funds, U.S. Treasury Bills or other securities and instruments held by the Lender in the Collateral Account will be turned over to the Borrowers or to such other person who may be entitled to the same under applicable laws.

7.6. Application of Proceeds. During the continuance of any Event of Default, any proceeds of the collection of the Obligations and/or the sale or other disposition of the Collateral will be applied by the Lender to the payment of Enforcement Costs, and any balance of such proceeds (if any) will be applied by the Lender to the payment of the remaining Obligations (whether then due or not), at such time or times and in such order and manner of application as the Lender may from time to time in its sole discretion determine. If the sale or other disposition of the Collateral fails to satisfy all of such Obligations, the Borrowers shall remain liable to the Lender for any deficiency.

7.7. Remedies, etc. Cumulative. Each right, power and remedy of the Lender as provided for in this Agreement or in the other Financing Documents or now or hereafter existing under applicable laws or otherwise shall be cumulative and concurrent and shall be in addition to every other right, power or remedy provided for in this Agreement or in the other Financing Documents or now or hereafter existing under applicable laws or otherwise, and the exercise or beginning of the exercise by the Lender of any one or more of such rights, powers or remedies shall not preclude the simultaneous or later exercise by the Lender of any or all such other rights, powers or remedies.

7.8. No Waiver, Etc. No failure or delay by the Lender to insist upon the strict performance of any term, condition, covenant or agreement of this Agreement or of the other Financing Documents, or to exercise any right, power or remedy consequent upon a breach thereof, shall constitute a waiver of any such term, condition, covenant or agreement or of any such breach, or preclude the Lender from exercising any such right, power or remedy at any later time or times. By accepting payment after the due date of any amount payable under this Agreement or under any of the other Financing Documents, the Lender shall not be deemed to waive the right either to require prompt payment when due of all other amounts payable under

this Agreement or under any of the other Financing Documents, or to declare an Event of Default for failure to effect such prompt payment of any such other amount. The payment by the Borrowers or any other person and the acceptance by the Lender of any amount due and payable under the provisions of this Agreement or the other Financing Documents at any time during which an Event of Default exists shall not in any way or manner be construed as a waiver of such Event of Default by the Lender or preclude the Lender from exercising any right of power or remedy consequent upon such Event of Default.

7.9 Arbitration.

(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 the 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 of 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 in Washington, D.C. All Claims shall be determined by one arbitrator; however, if Claims exceed Five Million Dollars ($5,000,000), upon the request of any party, the Claims shall be decided by three arbitrators. All arbitration hearings shall commence within ninety (90) days of the demand for arbitration and close within ninety (90) days of commencement and the award of the arbitrator(s) shall be issued within thirty (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 sixty (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 reasonable legal fees pursuant to the terms of this Agreement.

(f) This paragraph does not limit the right of any party to: (i) exercise self-help remedies, such as but not limited to, setoff; (ii) initiate judicial or non-judicial 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 not 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.

SECTION 8. Miscellaneous.

8.1. Course of Dealing; Amendment. No course of dealing between the Lender and the Borrowers shall be effective to amend, modify or change any provision of this Agreement or the other Financing Documents. The Lender shall have the right at all times to enforce the provisions of this Agreement and the other Financing Documents in strict accordance with the provisions hereof and thereof, notwithstanding any conduct or custom on the part of the Lender in refraining from so doing at any time or times. The failure of the Lender at any time or times to enforce its rights under such provisions, strictly in accordance with the same, shall not be construed as having created a custom in any way or manner contrary to specific provisions of this Agreement or the other Financing Documents or as having in any way or manner modified or waived the same. This Agreement and the other Financing Documents to which the Borrowers are a party may not be amended, modified, or changed in any respect except by an agreement in writing signed by the Lender and the Borrowers.

8.2. Waiver of Default. The Lender may, at any time and from time to time, execute and deliver to the Borrowers a written instrument waiving, on such terms and conditions as the Lender may specify in such written instrument, any of the requirements of this Agreement or of the other Financing Documents or any Event of Default or Default and its consequences, provided, that any such waiver shall be for such period and subject to such conditions as shall be specified in any such instrument. In the case of any such waiver, the Borrowers and the Lender shall be restored to their former positions prior to such Event of Default or Default and shall have the same rights as they had hereunder. No such waiver shall extend to any subsequent or other Event of Default or Default, or impair any right consequent thereto and shall be effective only in the specific instance and for the specific purpose for which given.

8.3. Notices. All notices, requests and demands to or upon the parties to this Agreement shall be deemed to have been given or made when delivered by hand, or when received after being deposited in the mail, postage prepaid by registered or certified mail, return receipt requested, one day after being sent by reputable overnight delivery service, or, in the case of notice by telegraph, telex or facsimile transmission, when properly transmitted, addressed as follows or to such other address as may be hereafter designated in writing by one party to the other:
