As used in this Guarantee, terms defined in the Revolving Credit Agreement (unless otherwise defined herein) are used herein as therein defined, and the following terms shall have the following meanings (such meanings to be, when appropriate, equally applicable to both the singular and plural forms of the terms defined): "Agent" shall have the meaning specified in the preamble hereof. "Guarantee" shall have the meaning specified in the preamble hereof. "Guarantors" shall have the meaning specified in the preamble hereof.

"Maximum Guaranteed Amount" for any Guarantor shall mean the amount which can be guaranteed by such Guarantor under applicable federal and state laws relating to the insolvency of debtors. "Revolving Credit Agreement" shall have the meaning specified in the first whereas clause hereof. SECTION 2. Guarantee. (a) Each of the Guarantors hereby, jointly and severally, absolutely, unconditionally and irrevocably guarantees to the Agent and the Lenders and their respective successors, indorsees, transferees and assigns the prompt and complete payment by the Company when due (whether at the stated maturity, by acceleration or otherwise) of the Obligations, and each Guarantor further agrees to pay any and all expenses (including, without limitation, all reasonable fees and disbursements of counsel) which may be paid or incurred by the Agent or any Lender in enforcing, or obtaining advice of counsel in respect of, any rights with respect to, or collecting, any or all of the Obligations and/or enforcing any rights with respect to, or collecting against, such Guarantor under this Guarantee; provided, however, that, notwithstanding anything to the contrary contained herein or in any other Credit Document, the maximum liability of each Guarantor hereunder and under the other Credit Documents shall in no event exceed such Guarantor's Maximum Guaranteed Amount. This Guarantee constitutes a present and continuing guarantee of payment and performance when due and not of collection, and each of the Guarantors, as a primary obligor and not as a surety, specifically agrees that no Guarantor shall be entitled to require that the Agent or any Lender exercise any right, assert any claim or demand, foreclose against or enforce any remedy whatsoever against the Company (or any other Person) before or as a condition to the obligations of such Guarantor hereunder. Each Guarantor hereby acknowledges that it is fully aware of the terms and conditions and has received a copy of each Credit Document to which it or any other Credit Party is a party and is fully aware of the transactions contemplated thereby. (b) Each Guarantor agrees that the Obligations may at any time and from time to time exceed the Maximum Guaranteed Amount of such Guarantor or of all of the Guarantors without impairing this Guarantee or affecting the rights and remedies of the Agent and the Lenders hereunder. (c) No payment or payments made by the Company, any of the Guarantors, any other guarantor or any other Person or received or collected by the Agent or any Lender from the Company, any of the Guarantors, any other guarantor or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder which shall, notwithstanding any such payment or payments other than payments made by such Guarantor in respect of the Obligations or payments received or collected from such Guarantor in respect of the Obligations, remain liable for the Obligations up to its Maximum Guaranteed Amount until such time as the Obligations are paid in full, no Standby Letters of Credit are outstanding or not fully cash collateralized and the Commitments are terminated. (d) Each Guarantor agrees that whenever, at any time or from time to time, it shall make any payment to the Agent or any Lender on account of its liability hereunder, it will notify the Agent in writing that such payment is made under this Guarantee for such purpose. SECTION 3. Right of Contribution. Each Guarantor hereby agrees that to the extent that a Guarantor shall have paid more than its proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and receive contribution from and against any other Guarantor hereunder who has not paid its proportionate share of such payment. Each Guarantor's right of contribution shall be subject to the terms and conditions of Section 5 hereof. The provisions of this Section 3 shall in no respect limit the obligations and liabilities of any Guarantor to the Agent and the Lenders, and each Guarantor shall remain liable to the Agent and the Lenders for the full amount guaranteed by such Guarantor hereunder. SECTION 4. Right of Set-off. Upon the occurrence and during the continuance of any Event of Default specified in the Revolving Credit Agreement, each Guarantor hereby irrevocably authorizes each Lender at any time and from time to time without notice to such Guarantor or any other Guarantor, any such notice being expressly waived by each Guarantor, to set-off and appropriate and apply any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender to or for the credit or the account of such Guarantor, or any part thereof, in such amounts as such Lender may elect, against and on account of the obligations and liabilities of such Guarantor to such Lender hereunder and claims of every nature and description of such Lender against such Guarantor, in any currency, whether arising hereunder, under the Revolving Credit Agreement, the Revolving Notes, the Swing Line Note, the Standby Letters of Credit or otherwise under any other Credit Document, as such Lender may elect, whether or not the Agent or any Lender has made any demand for payment and although such obligations, liabilities and claims may be contingent or unmatured. Each Lender agrees to notify such Guarantor promptly of any such set-off and the application made by such Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) which such Lender may have. SECTION 5. Subrogation, etc. Notwithstanding any payment or payments made by any of the Guarantors hereunder or any set-off or application of funds of any of the Guarantors by any Lender, no Guarantor shall exercise any of the rights of the Agent or any Lender which the Guarantor may acquire by way of subrogation, by any payment made hereunder, by reason of such set-off or application of funds or otherwise, against the Company or any other Guarantor or any collateral security or guarantee or right of set-off held by any Lender for the payment of the Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Agent and the Lenders by the Company on account of the Obligations are paid in full, no Standby Letters of Credit are outstanding or not fully cash collateralized and the Commitments are terminated. If any amount shall be paid to any Guarantor on account of such subrogation or reimbursement rights at any time when all of the Obligations shall not have been paid in full, any Standby Letter of Credit shall be outstanding or not fully cash collateralized or the Commitments shall not have been terminated, such amount shall be held by such Guarantor in trust for the Agent and the Lenders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Agent in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Agent, if required), to be applied against the Obligations, whether matured or unmatured, in such order as required by the applicable Credit Documents. SECTION 6. Amendments, etc. with respect to the Obligations; Waiver of Rights. Each Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, (i) any demand for payment of any of the Obligations made by the Agent or any Lender may be rescinded by such party and any of the Obligations continued, (ii) the Obligations, or the liability of any other party upon or for any part thereof, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Agent or any Lender, (iii) the Revolving Credit Agreement, the Revolving Notes, the Swing Line Note, the other Credit Documents, any Standby Letter of Credit and any other collateral security document or other guarantee or document in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Agent and/or any Lender may deem advisable from time to time, and (iv) any collateral security, guarantee or right of set-off at any time held by the Agent or any Lender for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. Neither the Agent nor any Lender shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for this Guarantee or any property subject thereto. When making any demand hereunder against any of the Guarantors, the Agent or any Lender may, but shall be under no obligation to, make a similar demand on the Company or any other Guarantor or guarantor, and any failure by the Agent or any Lender to make any such demand or to collect any payments from the Company or any such other Guarantor or guarantor or any release of the Company or such other Guarantor or guarantor shall not relieve any of the Guarantors in respect of which a demand or collection is not made or any of the Guarantors not so released of their several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Agent or any Lender against any of the Guarantors. For the purposes hereof "demand" shall include the commencement and continuance of any legal proceedings. EACH GUARANTOR EXPRESSLY AND IRREVOCABLY WAIVES THE BENEFITS AFFORDED TO IT UNDER SECTIONS 49-25 AND 49-26 OF THE CODE OF VIRGINIA (1950), AS AMENDED, OR ANY SIMILAR STATUTE OR COMMON LAW. SECTION 7. Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of reliance by the Agent or any Lender upon this Guarantee or acceptance of this Guarantee. The Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, annexed or waived, in reliance upon this Guarantee, and all dealings between the Company or any of the Guarantors and the Agent or any Lender shall likewise be conclusively presumed to have been had or consummated in reliance upon this Guarantee. Each Guarantor waives diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the Company or any of the Guarantors with respect to the Obligations or this Guarantee. Each Guarantor understands and agrees that this Guarantee shall be construed as a continuing, absolute and unconditional guarantee of payment, and not of collection, without regard to (whether or not the Guarantor or the Company shall have any knowledge or notice of any of the following) (a) the validity, regularity or enforceability of the Revolving Credit Agreement, the Revolving Notes, the Swing Line Note, the Standby Letters of Credit, any of the other Credit Documents, any of the Obligations or any other collateral security therefore or guarantee or right of set-off with respect thereto at any time or from time to time held by the Agent or any Lender, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by the Company against the Agent or any Lender, (c) any termination, amendment or modification of, or deletion from, or addition or supplement to, or other change in any of the Credit Documents or any other instrument or agreement applicable to any of the parties to such agreements, or any furnishing or acceptance of additional security, or any release of, exchange or action with respect to any security, for the obligations of the Company under the Credit Documents, or the failure of any security or the failure of any Person to perfect any interest in any collateral security; (d) any exercise, nonexercise or waiver of any right, remedy, power or privilege under or in respect of any Credit Document or any obligation or liability contained therein or any failure to mitigate damages under any Credit Document or any waiver of any such right, remedy, power or privilege or any failure to give any notice (including notice of an Event of Default) to any Credit Party; (e) any extension of time for payment of any Obligation, or of the time for performance of any other obligations, covenants or agreements under or arising out of any Credit Document, or the extension or the renewal of any thereof; and (f) any other law, rule, regulation, event, condition or circumstance whatsoever (with or without notice to or knowledge of the Company or such Guarantor) which constitutes, or might be construed to constitute, an equitable or legal discharge of the Company for the Obligations, or of such Guarantor under this Guarantee (or of a guarantor or surety in general), in bankruptcy or in any other instance. When pursuing its rights and remedies hereunder against any Guarantor, the Agent and any Lender may, but shall be under no obligation to, pursue such rights and remedies as it may have against the Company or any other Person or against any collateral security or guarantee for the Obligations or any right of set-off with respect thereto, and any failure by the Agent or any Lender to pursue such other rights or remedies or to collect any payments from the Company or any such other Person or to realize upon any such collateral security or guarantee or to exercise any such right of set-off, or any release of the Company or any such other Person or any such collateral security, guarantee or right of set-off, shall not relieve such Guarantor of any liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Agent or any Lender against such Guarantor. This Guarantee shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon each Guarantor and the successors and assigns thereof, and shall inure to the benefit of the Agent and the Lenders, and their respective successors, indorsees, transferees and assigns, until all the Obligations and the obligations of each Guarantor under this Guarantee shall have been satisfied by payment in full, no Standby Letter of Credit shall remain outstanding or not fully cash collateralized and the Commitments shall be terminated, notwithstanding that from time to time during the term of the Revolving Credit Agreement the Company may be free from any Obligations.

If an event permitting the declaration of default under a Credit Document shall at any time have occurred and be continuing, and such declaration of default shall at such time be prevented by reason of the pendency against the Company or any other Person of a case or proceeding under a bankruptcy or insolvency law, each Guarantor agrees that, for purposes of this Guarantee and its obligations hereunder, such Credit Document shall be deemed to have been declared in default with the same effect as if such Credit Document had been enforceable in accordance with the terms thereof, and each Guarantor shall forthwith pay the amounts specified by the Agent or any Lenders to be paid thereunder, any interest thereon and any other amounts guaranteed hereunder without further notice or demand. SECTION 9. Payments; Execution and Delivery Taxes. Each Guarantor hereby guarantees that payments hereunder will be paid to the Agent without set-off or counterclaim in U.S. Dollars at the office of the Agent located at NationsBank, N.A., Kay Finlaw-Creel, VA-200-05-02, 8300 Greensboro Drive, Suite 550, McLean, VA 22102, or such other office of the Agent in the United States of America as the Agent may from time to time designate to the Guarantors by written notice.

No failure to exercise, nor any delay in exercising, on the part of the Agent or any Lender, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Agent or any Lender of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Agent or such Lender would otherwise have on any future occasion.
