(d) No Subsidiary is a party to, or otherwise subject to, any legal restriction or any agreement (other than this Agreement, the agreements listed on Schedule 5.4 and customary limitations imposed by corporate law or limited liability company law statutes) restricting the ability of such Subsidiary to pay dividends out of profits or make any other similar distributions of profits to the Company or any Subsidiary that owns outstanding shares of capital stock or similar equity interests of such Subsidiary. 6

Section 5.5. Financial Statements; Financial Projections. The Company has delivered to each Purchaser copies of the consolidated financial statements of the Company and the Subsidiaries listed on Schedule 5.5. All of such consolidated financial statements (including in each case the related schedules and notes) fairly present in all material respects the consolidated financial position of the Company and its Subsidiaries as of the respective dates specified in such financial statements and the consolidated results of their operations and cash flows for the respective periods so specified and have been prepared in accordance with GAAP consistently applied throughout the periods involved except as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments and other adjustments described therein). The financial projections for the Company and its Subsidiaries for the fiscal year ending December 31, 2002 are set forth in the Memorandum under tab number VI.

The Company has no reason to believe that such forecasts are unreasonable in any material respect. Section 5.6. Compliance with Laws, Other Instruments, Etc. The execution, delivery and performance by the Company of this Agreement, the Collateral Documents and the Notes will not (a) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of the Company or any Subsidiary under, any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, corporate charter or by-laws, or any other agreement or instrument to which the Company or any Subsidiary is bound or by which the Company or any Subsidiary or any of their respective properties may be bound or affected, (b) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable to the Company or any Subsidiary or (c) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Company or any Subsidiary.

(b) Neither the Company nor any Subsidiary is in default under any term of any agreement or instrument to which it is a party or by which it is bound, or any order, judgment, decree or ruling of any court, arbitrator or Governmental Authority or is in violation 7

of any applicable law, ordinance, rule or regulation (including, without limitation, Environmental Laws) of any Governmental Authority, which default or violation, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect. Section 5.9. Taxes. The Company and its Subsidiaries have filed all tax returns that are required to have been filed in any jurisdiction, and have paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon them or their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for any taxes and assessments (a) the amount of which is not individually or in the aggregate Material or (b) the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the Company or a Subsidiary, as the case may be, has established adequate reserves in accordance with GAAP. The Company knows of no basis for any other tax or assessment that could reasonably be expected to have a Material Adverse Effect.

If such Proposed Purchase Date is in connection with an offer contemplated by subparagraph (a) of this Section 8.3, such date shall be not less than 30 days 17

and not more than 60 days after the date of such offer (if the Proposed Purchase Date shall not be specified in such offer, the Proposed Purchase Date shall be the 45th day after the date of such offer).

The purchase shall be made on the Proposed Purchase Date. (f) Deferral Pending Change in Control. The obligation of the Company to purchase Notes pursuant to the offers required by subparagraph (b) and accepted in accordance with subparagraph (d) of this Section 8.3 is subject to the occurrence of the Change in Control in respect of which such offers and acceptances shall have been made. In the event that such Change in Control does not occur on or prior to the Proposed Purchase Date in respect thereof, the purchase shall be deferred in accordance with the terms and provisions of this clause (f) until and shall be made on the date on which such Change in Control occurs. The Company shall keep each holder of Notes reasonably and timely informed of (i) any such deferral of the date of purchase, (ii) the date on which such Change in Control and the purchase are expected to occur, and (iii) any determination by the Company that efforts to effect such Change in Control have ceased or been abandoned (in which case the offers and acceptances made pursuant to this Section 8.3 in respect of such Change in Control shall be deemed rescinded). The deferred purchase of the Notes by the Company pursuant to this clause (f) is conditioned upon the payment by the Company to the holders who accept such purchase offer pursuant to this Section 8.3 of all losses, expenses, liabilities and costs suffered by such holder as a result of the deferral of such purchase in connection with any hedging contract or position entered into by such holder in reliance on the determination of the original Proposed Purchase Date (the "Deferred Payment Hedging Loss"). Such Deferred Payment Hedging Loss, if any, shall be reasonably determined and established by such holder and a reasonable explanation of the same shall be communicated to the Company. Such Deferred Payment Hedging Loss shall be due and payable on the deferred Proposed Purchase Date.

Section 8.6. Purchase of Notes. The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except upon the purchase, payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes. Section 8.7. Make-Whole Amount. The term "Make-Whole Amount" means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings: "Called Principal" means, with respect to any Note, the principal of such Note that is to be prepaid or purchased pursuant to Section 8.2 or Section 8.3 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. "Discounted Value" means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal. "Reinvestment Yield" means, with respect to the Called Principal of any Note, .50% over the yield to maturity implied by (i) the yields reported, as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated the "PX Screen" on the Bloomberg Financial Markets Service Screen (or such other display as may replace "PX Screen" on Bloomberg Financial Markets Service) for actively traded U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable, the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. Such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond-equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) 20

the actively traded U.S. Treasury security with the maturity closest to and greater than the Remaining Average Life and (2) the actively traded U.S. Treasury security with the maturity closest to and less than the Remaining Average Life. "Remaining Average Life" means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment. "Remaining Scheduled Payments" means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment or purchase of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2, 8.3 or 12.1. "Settlement Date" means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid or purchased pursuant to Section 8.2 or Section 8.3 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances. 31

Section 12.2. Other Remedies. If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise. Section 12.3. Rescission. At any time after any Notes have been declared due and payable pursuant to the second or third sentence of Section 12.1, the holders of not less than 66-2/3% in principal amount of the Notes then outstanding, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and Make-Whole Amount, if any, and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 17, and (c) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment under this Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right consequent thereon. Section 12.4. No Waivers or Election of Remedies, Expenses, Etc. No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder's rights, powers or remedies. No right, power or remedy conferred by this Agreement or by any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 15, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys' fees, expenses and disbursements.

Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of Notes. Notes shall not be transferred in denominations of less than $1,000,000, provided that if necessary to enable the registration of transfer by a holder of its entire holding of Notes, one Note may be in a denomination of less than $1,000,000.

Subject to Section 14.2, payments of principal, Make-Whole Amount, if any, and interest becoming due and payable on the Notes shall be made in New York, New York at the principal office of The Chase Manhattan Bank in such jurisdiction.

Section 14.2. Home Office Payment. So long as you or your nominee shall be the holder of any Note, and notwithstanding anything contained in Section 14.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole 33

Amount, if any, and interest by the method and at the address specified for such purpose below your name in Schedule A, or by such other method or at such other address as you shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, you shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 14.1. Prior to any sale or other disposition of any Note held by you or your nominee you will, at your election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 13.2.

(b) Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security, to any holder of Notes as consideration for or as an inducement to the entering into by any holder of Notes of any waiver or amendment of any of the terms and provisions hereof or of the Notes unless such remuneration is concurrently paid, or security is concurrently granted, on the same terms, ratably to each holder of Notes then outstanding whether or not such holder consented to such waiver or amendment. Section 17.3. Binding Effect, Etc.

No course of dealing between the Company and the holder of any Note nor any delay in exercising any rights hereunder or under any Note 35

This Section 19 shall not prohibit the Company or any other holder of Notes from contesting any such reproduction to the same extent that it could 36

contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction. SECTION 20 Confidential Information. For the purposes of this Section 20, "Confidential Information" means information delivered to you by or on behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified in writing when received by you as being confidential information of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to you prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by you or any Person acting on your behalf, (c) otherwise becomes known to you other than through disclosure by the Company or any Subsidiary or (d) constitutes financial statements delivered to you under Section 7.1 that are otherwise publicly available.

Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee or any holder that shall have previously delivered such a confirmation), such holder will confirm in writing that it is bound by the provisions of this Section 20. SECTION 21 Substitution of Purchaser. 37

You shall have the right to substitute any one of your Affiliates as the purchaser of the Notes that you have agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by both you and such Affiliate, shall contain such Affiliate's agreement to be bound by this Agreement and shall contain a confirmation by such Affiliate of the accuracy with respect to it of the representations set forth in Section 6. Upon receipt of such notice, wherever the word "you" is used in this Agreement (other than in this Section 21), such word shall be deemed to refer to such Affiliate in lieu of you. In the event that such Affiliate is so substituted as a purchaser hereunder and such Affiliate thereafter transfers to you all of the Notes then held by such Affiliate, upon receipt by the Company of notice of such transfer, wherever the word "you" is used in this Agreement (other than in this Section 21), such word shall no longer be deemed to refer to such Affiliate, but shall refer to you, and you shall have all the rights of an original holder of the Notes under this Agreement. SECTION 22 Release of Collateral. You and each subsequent holder of a Note agree to release any Collateral from the Collateral Documents at such time as either (a) the Bank Lender releases such Collateral from the Collateral Documents with respect to Revolving Credit Loan Obligations; or (b) all amounts due and owing under the Credit Agreement as in effect on the Closing or as amended (but not refinanced or replaced) with respect to the Revolving Credit Loan Obligations is paid in full and the Company shall not have executed and delivered a Qualified Replacement Credit Agreement and no other holder of Debt of the Company shall have required that the Collateral be pledged to secured such Debt; provided, however, that you and each subsequent holder will not be required to release any Collateral from the Collateral Documents under the circumstances contemplated herein if a Default or Event of Default has occurred and is continuing. Your obligation to release any Collateral from the Collateral Documents is conditioned upon your prior receipt of a certificate from a Senior Financial Officer of the Company stating that the circumstances and conditions described in this Section 22 have occurred and have been satisfied. If at any time subsequent to the release above, the Bank Lender or any other holder of Debt requires that the Collateral be pledged or repledged to secure the Company's obligations under the Credit Agreement or such other evidence of Debt, the Company shall grant a first perfected security interest in the Collateral to the Noteholders, in addition to any such party. In addition to the execution of a valid Security Agreement in the form of Exhibit 4.10 hereto, the Company shall provide to you and the Other Purchasers and you and the Other Purchasers shall have received the following, in form and substance satisfactory to you and the Other Purchasers: (i) evidence that all filings, registrations and recordings have been made in the appropriate governmental offices, and all other action has been taken, which shall be necessary to create, in favor of the Collateral Agent on behalf of the Secured Parties, a perfected first priority Lien on the Collateral, including evidence of filing of completed UCC-1 financing statements, in each case in the appropriate governmental offices; (ii) the results, dated as of a recent date prior to the filing date, of searches conducted in the UCC filing records in each of the governmental offices in each jurisdiction in which Collateral is located, which shall have revealed no Liens with respect to any of the Collateral; 38

(iii) an opinion of counsel for the Company in form and substance satisfactory to you and the Other Purchasers in your reasonable discretion regarding the transactions contemplated thereby; and (iv) such due diligence and resolutions or other authorizations from the Company reasonably acceptable to you and the Other Purchasers. SECTION 23 Miscellaneous. Section 23.1. Successors and Assigns. All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not. Section 23.2. Payments Due on Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding, any payment of principal of or Make-whole Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day. Section 23.3. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction. Section 23.4. Construction. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. Section 23.5. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto. Section 23.6. Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the State of New York excluding choice-of-law principles of the law of such State that would require the application of the laws of a jurisdiction other than such State. * * * * 39

SECTION 5 - COVENANTS Until all of the Obligations have been finally and indefeasibly paid and satisfied in full and the Revolving Commitment terminated, the Debtor covenants and agrees that: 5.1 Perfection and Protection of Security Interest. (a) The Debtor shall, at its expense, perform all steps reasonably requested by the Collateral Agent at any time to perfect, maintain, protect, and enforce the Collateral Agent's Liens, including: (i) filing financing or continuation statements, and amendments thereof, in form and substance reasonably satisfactory to the Collateral Agent; (ii) delivering to the Collateral Agent warehouse receipts covering any portion of the Collateral located in warehouses and for which warehouse receipts are issued and certificates of title covering any portion of the Collateral for which certificates of title have been issued; (iii) when any Event of Default has occurred and is continuing, transferring Inventory to warehouses or other locations designated by the Collateral Agent; (iv) placing notations on the Debtor's books of account to disclose the Collateral Agent's security interest; and (v) taking such other steps as are deemed reasonably necessary or desirable by the Collateral Agent to maintain and protect the Collateral Agent's Liens. Notwithstanding the foregoing, unless any Event of Default shall have occurred and be continuing, the Debtor shall not be required to take any action to perfect the Collateral Agent's Liens in (w) Investment Property with an aggregate value less than $100,000, (x) any Letter-of-Credit Rights with respect to any letter of credit with a face amount of $150,000 or less, but only to the extent that the aggregate face amount of all letters of credit does not exceed $750,000, (y) any Deposit Account with a balance of $150,000 or less at the close of any Business Day, but only to the extent that the aggregate number of Deposit Accounts does not exceed five (5) at any time, or (z) electronic chattel paper in an aggregate amount of less than $100,000. The Debtor agrees that a carbon, photographic, photostatic, or other reproduction of this Security Agreement or of a financing statement is sufficient as a financing statement. (b) Upon the Collateral Agent's request, the Debtor shall deliver to the Collateral Agent all Collateral consisting of negotiable Documents, certificated securities (accompanied by stock powers executed in blank), Chattel Paper and Instruments promptly after the Debtor receives the same. (c) Subject to Section 5.1(a) hereof, the Debtor shall take all steps necessary to grant the Collateral Agent control of all electronic chattel paper in accordance with the UCC. (d) The Debtor hereby irrevocably authorizes the Collateral Agent at any time and from time to time to file in any filing office in any Uniform Commercial Code jurisdiction -8-

any initial financing statements and amendments thereto that (a) indicate the Collateral (i) as all personal property assets of the Debtor or words of similar effect, regardless of whether any particular asset comprised in the Collateral falls within the scope of Article 9 of the UCC of the State of Delaware or such jurisdiction, or (ii) as being of an equal or lesser scope or with greater detail, and (b) contain any other information required by part 5 of Article 9 of the UCC of the State of Delaware for the sufficiency or filing office acceptance of any financing statement or amendment, including (A) whether the Debtor is an organization, the type of organization and any organizational identification number issued to the Debtor, and (B) in the case of a financing statement filed as a fixture filing or indicating Collateral as as-extracted collateral or timber to be cut, a sufficient description of the real property to which the Collateral relates. The Debtor agrees to furnish any such information to the Collateral Agent promptly upon request, and to pay on demand all fees, costs and expenses associated with all such filings. The Debtor also ratifies its authorization for the Collateral Agent to have filed in any Uniform Commercial Code jurisdiction any like initial financing statements or amendments thereto if filed prior to the date hereof. (e) The Debtor shall promptly notify the Collateral Agent of any commercial tort claim (as defined in the UCC) in excess of $250,000 acquired by it and unless otherwise consented to by the Collateral Agent, the Debtor shall enter into a supplement to this Security Agreement, granting to the Collateral Agent a Lien in such commercial tort claim. (f) Upon the Collateral Agent's request, but not more frequently than once during each calendar year, the Debtor shall provide to the Collateral Agent a certificate of good standing from its state of incorporation or organization. (g) Without limiting the prohibitions on mergers involving the Debtor contained in the Credit Agreement and the Note Agreement, the Debtor will not change its name, operate under any assumed name, change its structure, reincorporate or reorganize itself, or change its jurisdiction of incorporation without giving the Collateral Agent at least thirty (30) days' prior written notice and, unless prior to such change, the Debtor shall have taken all action reasonably necessary or desirable or that the Collateral Agent may reasonably request, to preserve, perfect, confirm and protect in the manner and to the extent provided for in this Security Agreement the security interests granted hereby. (h) The Debtor acknowledges that it is not authorized to file any financing statement or amendment or termination statement with respect to any financing statement without the prior written consent of the Collateral Agent and agrees that it will not do so without the prior written consent of the Collateral Agent, subject to the Debtor's rights under Section 9-509(d)(2) of the UCC. (i) The Debtor shall not, except in connection with any Permitted Lien, enter into any contract or agreement that restricts or prohibits the grant of a security interest in Accounts, Chattel Paper, Instruments or payment intangibles or the proceeds of the foregoing to the Collateral Agent. 5.2 Accounts. (a) The Debtor shall not re-date any invoice, provided that the Debtor shall have the right, in the exercise of its reasonable business judgment, to re-date -9-

invoices that in the aggregate do not exceed at any one time $100,000. The Debtor shall not make sales on extended terms dating beyond that customary in the Debtor's business (which customary terms include customer incentive terms) or extend or modify any Account except in the ordinary course of business. (b) The Debtor shall not accept any note or other instrument (except a check or other instrument for the immediate payment of money) with respect to any Account without providing to the Collateral Agent prompt written notice thereof. Any such instrument shall be considered as evidence of the Account and not payment thereof and the Debtor will promptly deliver such instrument to the Collateral Agent, endorsed without recourse by the Debtor to the Collateral Agent in a manner reasonably satisfactory in form and substance to the Collateral Agent. (c) The Debtor shall notify the Collateral Agent promptly of all disputes and claims in excess of $250,000 with any Account Debtor, and agrees to settle, contest, or adjust such dispute or claim at no expense to the Collateral Agent. No discount, credit or allowance shall be granted to any such Account Debtor without the Collateral Agent's prior written consent, except for discounts, credits and allowances made or given in the ordinary course of the Debtor's business when no Event of Default exists hereunder. The Debtor shall send the Collateral Agent a copy of each credit memorandum in excess of $250,000 as soon as issued, and the Debtor shall promptly report that credit on Borrowing Base Certificates submitted by it. (d) If an Account Debtor returns any Inventory to the Debtor when no Event of Default exists, then the Debtor shall promptly determine the reason for such return and shall issue a credit memorandum to the Account Debtor in the appropriate amount. The Debtor shall immediately report to the Collateral Agent any return involving an amount in excess of $250,000. Each such report shall indicate the reasons for the return and the locations and condition of the returned Inventory. In the event any Account Debtor returns Inventory to the Debtor when any Event of Default exists, the Debtor, upon the request of the Collateral Agent, shall: (i) hold the returned Inventory in trust for the Collateral Agent; (ii) segregate all returned Inventory from all of its other property; (iii) dispose of the returned Inventory solely according to the Collateral Agent's written instructions; and (iv) not issue any credits or allowances with respect thereto without the Collateral Agent's prior written consent. All returned Inventory shall be subject to the Collateral Agent's Liens thereon. Whenever any Inventory is returned, the related Account shall be deemed ineligible to the extent of the amount owing by the Account Debtor with respect to such returned Inventory and such returned Inventory shall not be Eligible Inventory. 5.3 Inventory. (a) The Debtor will keep its Inventory in good and marketable condition, except for damaged or defective goods arising in the ordinary course of the Debtor's business. The Debtor will not, without the prior written consent of the Collateral Agent, acquire or accept any Inventory on consignment or approval. The Debtor agrees that all Inventory produced by the Debtor in the United States of America will be produced in accordance with the Federal Fair Labor Standards Act of 1938, as amended, and all rules, regulations, and orders thereunder. The Debtor will conduct a physical count of the Inventory at least once during each of its fiscal years, and after and during the continuation of any Event of Default, at such other times as the Collateral Agent requests. The Debtor will maintain a perpetual inventory reporting -10-

system at all times. The Debtor will not, without the Collateral Agent's written consent, sell any Inventory on a bill-and-hold, guaranteed sale, sale and return, sale on approval, consignment, or other repurchase or return basis. (b) In connection with all Inventory financed by a Letter of Credit with a face amount in excess of $150,000, the Debtor will, at the Collateral Agent's request, instruct all suppliers, carriers, forwarders, customs brokers, warehouses or others receiving or holding cash, checks, Inventory, Documents or Instruments in which the Collateral Agent holds a security interest to deliver them to the Collateral Agent and/or subject to the Collateral Agent's order, and if they shall come into the Debtor's possession, to deliver them, upon request, to the Collateral Agent in their original form. The Debtor shall also, at the Collateral Agent's request, designate the Collateral Agent as the consignee on all bills of lading and other negotiable and non-negotiable documents. 5.4 Equipment. The Debtor shall keep and maintain its Equipment in good operating condition and repair (ordinary wear and tear excepted) and shall make all necessary replacements thereof. The Debtor shall not permit any Equipment that is part of the Collateral to become a fixture with respect to real property or to become an accession with respect to other personal property with respect to which real or personal property the Collateral Agent does not have a Lien. The Debtor will not, without the Collateral Agent's prior written consent, alter or remove any identifying symbol or number on any of the Debtor's Equipment constituting Collateral. Except to the extent permitted by the Credit Agreement and the Note Agreement, the Debtor shall not, without the Collateral Agent's prior written consent, sell, license, lease as a lessor, or otherwise dispose of any of the Equipment. The Debtor will not use the Equipment or any of the other Collateral illegally. 5.5 Patents, Trademarks and Copyrights. (a) The Debtor shall notify the Collateral Agent immediately if it knows or has reason to know that any application or registration relating to any patent, trademark or copyright (now or hereafter existing) will be abandoned or dedicated, or of any material adverse determination or development (including the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, the United States Copyright Office or any court) regarding the Debtor's ownership of any patent, trademark or copyright, its right to register the same, or to keep and maintain the same. (b) In no event shall the Debtor, either directly or through any agent, employee, licensee or designee, file an application for the registration of any patent, trademark or copyright with the United States Patent and Trademark Office, the United States Copyright Office or any similar office or agency without giving the Collateral Agent prior written notice thereof, and, upon request of the Collateral Agent, the Debtor shall execute and deliver any and all such agreements, assignments and security agreements as the Collateral Agent may reasonably request to evidence the Collateral Agent's Lien on such patent, trademark or copyright, and the General Intangibles of the Debtor relating thereto or represented thereby. (c) The Debtor shall take all actions necessary or advisable, in the exercise of its prudent business judgment, to maintain and pursue each application, to obtain the relevant -11-

registration and to maintain the registration of each of the patents, trademarks and copyrights (now or hereafter existing), including the filing of applications for renewal, affidavits of use, affidavits of noncontestability and opposition and interference and cancellation proceedings. (d) In the event that any of the patent, trademark or copyright Collateral is infringed upon, or misappropriated or diluted by a third party, the Debtor shall notify the Collateral Agent promptly after the Debtor learns thereof. The Debtor shall, unless it shall reasonably determines that such patent, trademark or copyright Collateral is not material to the conduct of its business or operations, take such actions as the Debtor shall deem appropriate to protect such patent, trademark or copyright Collateral. 5.6 Maintenance of Records. The Debtor will keep and maintain, at its own cost and expense, in a manner consistent with past practice, complete and current records of the Collateral owned by it, including, but not limited to, a record of all shipments received, deliveries made, contracts performed, payments received, credits granted thereon and other dealings therewith. The Debtor shall timely provide the Collateral Agent with all such collateral reports as are required by the Credit Agreement and the Note Agreement, and all such additional reports as the Collateral Agent shall reasonably require. These reports shall be in the form previously provided to the Collateral Agent for its review or in form and detail as is reasonably satisfactory to the Collateral Agent. The Debtor will use all reasonable efforts to protect its records and books pertaining to any Collateral against fire, theft, loss or any other manner of destruction or loss. Such protection will consist of such protective means and devices as from time to time reasonably deemed necessary by the Collateral Agent. If the Debtor maintains its records of Accounts on a computer, it will maintain backup copies of such records, updated at reasonable intervals. 5.7 Inspection and Delivery of Collateral, Books and Records. The Collateral Agent or the Secured Parties, or any of them, or their respective agents, may at any reasonable time and from time to time and, if no Event of Default has occurred, upon reasonable prior notice, inspect the Collateral, and the books and records of the Debtor pertaining thereto. Not more frequently than one (1) time during each calendar year if no Event of Default has occurred and is continuing (there being no such limitation if any Event of Default has occurred and is continuing), the Debtor shall, at its own expense and cost, deliver or make available, at the Collateral Agent's election, books and records pertaining to the Accounts (including chattel paper) to the Collateral Agent, or any designated agent of the Collateral Agent, at such time and place as the Collateral Agent may reasonably request. 5.8 Expenses. The Debtor shall be liable for, and agrees to pay the Collateral Agent on demand, any and all reasonable expenses incurred or paid by the Collateral Agent or the Secured Parties, or any of them, in protecting or enforcing their respective rights under this Security Agreement, including, without limitation, reasonable attorneys' fees, whether incurred in collecting specific Accounts or otherwise. If the Debtor shall fail, in violation of the terms of the Credit Agreement or the Note Agreement, to discharge taxes, liens, security interests or other encumbrances on the Collateral, other than Permitted Liens, or to repair any damage to the Collateral, or to maintain or preserve the Collateral or to maintain adequate insurance on the Collateral, in each case within twenty (20) days after written notice from the Collateral Agent, the Collateral Agent may, at its option, discharge such taxes, liens, security interests or other -12-

encumbrances on or in the Collateral, pay for the repair or damage to the Collateral, pay for the maintenance and preservation of the Collateral, and/or pay for insurance on the Collateral. The Debtor agrees to reimburse the Collateral Agent on demand for any payments so made and, until such reimbursement, to pay interest thereon at a fluctuating rate of interest equal to the Default Rate applicable to the Revolving Loans from the date of the payment until reimbursement therefor, which reimbursement and interest shall be a part of the Obligations. Any payment made or other action taken by the Collateral Agent under this Section 5.8 shall be without prejudice to any right to assert an Event of Default hereunder and to proceed thereafter as herein provided. 5.9 Insurance. The Debtor will continuously insure the Collateral with a responsible company or companies reasonably satisfactory to the Collateral Agent against fire (with extended coverage) in the full insurable value of the Collateral, and against such other casualties and in such amounts and with such deductibles as are usually carried by owners of similar businesses and properties in the same general areas in which the Debtor operates. The insurance policy (or policies) shall have attached thereto a standard loss payable clause, without contribution, in favor of the Collateral Agent as agent for the Secured Parties as its interest may appear, and shall otherwise be in form reasonably acceptable to the Collateral Agent, and the Debtor will cause such policy (or policies) to provide that it (they) may not be canceled without thirty (30) days' prior written notice to the Collateral Agent. The Debtor will deliver to the Collateral Agent as agent for the Secured Parties evidence of the renewal or continuation of insurance at least ten (10) days before the expiration of the existing insurance. The Debtor hereby assigns to the Collateral Agent as agent for the Secured Parties any return of unearned premiums which may be due upon cancellation of any such policy or policies for any reason whatsoever and, upon the occurrence of any Event of Default and during the continuance thereof, directs the insurer(s) to pay to the Collateral Agent as agent for the Secured Parties any amounts so due. 5.10 Damage or Loss and Replacement. (a) The Debtor shall promptly notify the Collateral Agent of any fire, theft, water damage, vandalism or other damage to or loss of any Inventory or Equipment to the extent that the uninsured portion of such damaged or lost Inventory or Equipment is in excess of $250,000. In the case of any loss, damage to or destruction of the Inventory or Equipment or any part thereof, the Debtor, whether or not the insurance proceeds, if any, received on account of such damage or destruction shall be sufficient for that purpose, at the Debtor's cost and expense, will promptly repair or replace the Inventory or Equipment so lost, damaged or destroyed. (b) In the event that the Debtor or the Collateral Agent shall receive any proceeds of insurance with respect to Inventory, provided no Default or Event of Default then exists, (a) the Debtor shall pay to the Collateral Agent, or the Collateral Agent shall retain, as applicable, an amount of such proceeds equal to the balance then outstanding under the Revolving Credit Loan Obligations, which amount the Collateral Agent shall promptly pay to BB&T-VA for application to the Revolving Credit Loan Obligations, and the Debtor shall be entitled to retain, or the Collateral Agent shall pay to the Debtor, as applicable, any such excess insurance proceeds or (b) if there is no balance then outstanding under the Revolving Credit Loan Obligations, then the Debtor shall be entitled to retain, or the Collateral Agent shall pay to the Debtor, as applicable, all such proceeds of insurance with respect to Inventory. -13-

(c) In the event the Debtor shall receive any proceeds of insurance with respect to the Equipment in excess of $1,000,000 in the aggregate in any fiscal year of the Debtor, the Debtor shall immediately pay over such proceeds in excess of $1,000,000 to the Collateral Agent. Insurance proceeds received by the Collateral Agent under the provisions hereof or under any policy or policies of insurance covering the Equipment or any part thereof pursuant to the terms hereof in excess of $1,000,000 in the aggregate in any fiscal year of the Debtor shall be applied to the reduction of, or otherwise held as security for, the Secured Obligations (whether or not then due); provided, however, that the Collateral Agent agrees to release such insurance proceeds to the Debtor for the replacement, repair or restoration of the portion of the Equipment lost, damaged or destroyed if, but only if, (i) at the time of release no Default or Event of Default exists, (ii) a written request for such release is received from the Debtor within thirty (30) calendar days of receipt of, or in the event received by the Collateral Agent notice of the Collateral Agent's receipt of, such insurance proceeds and (iii) the Debtor provides the Collateral Agent purchase orders or invoices for replacement property for, or for the repair or restoration of, the Equipment that was lost, damaged or destroyed giving rise to the payment of such insurance proceeds within 210 days of the occurrence of such loss, damage or destruction. Notwithstanding the foregoing, if, following the application of insurance proceeds to replace, repair or restore Equipment as provided in this Section 5.10(c), there is an amount of such proceeds which is less than $50,000 remaining, provided that no Default or Event of Default shall have occurred and be continuing, the Collateral Agent shall return such amount to the Debtor. 5.11 Further Assurances. Subject to the provisions of Section 5.1(a) hereof, the Debtor will from time to time, at the sole expense of the Debtor, promptly execute, deliver, file and record (as appropriate) all further instruments and documents, and take all further action as the Collateral Agent or the Secured Parties, or any of them, may reasonably deem necessary or prudent in order to perfect, continue and protect the security interests granted hereby or to enable the Collateral Agent or the Secured Parties, or any of them, to exercise and enforce its rights and remedies hereunder with respect to the Collateral or any part thereof. SECTION 6 - SALES AND COLLECTIONS 6.1 Processing and Sales of Inventory. So long as no Event of Default shall have occurred and be continuing and the Collateral Agent shall not have notified the Debtor to the contrary, the Debtor shall have the right in the regular course of its business to process and sell the Inventory. The security interests granted hereunder to the Collateral Agent as agent for the Secured Parties shall attach to all proceeds of all sales, leases, or other dispositions of the Inventory. 6.2 Inventory Controls. Upon the occurrence and during the continuation of any Event of Default, the Collateral Agent or its agents may secure all entrances to those parts of the premises of the Debtor in which any Inventory is stored and keep such entrances locked or otherwise sealed or institute such other control measures with respect to the movement of Inventory as the Collateral Agent may deem necessary or prudent, subject to the rights of third parties under the Leases. -14-

6.3 Collection of Accounts. The Collateral Agent as agent for the Secured Parties hereby authorizes the Debtor to collect and dispose of the proceeds of the Accounts, which authority the Collateral Agent may curtail or terminate at any time following the occurrence and during the continuance of any Event of Default. After such authority has been curtailed or terminated, the Debtor shall, upon receipt of all checks, drafts, cash, and other remittances in payment of or on account of the Accounts, deposit the same in a special account designated by the Collateral Agent, over which account the Collateral Agent as agent for the Secured Parties alone shall have the power of withdrawal (the "Collection Account"). The remittance of the proceeds of such Accounts shall not, however, constitute payment or liquidation of such Accounts until the Collateral Agent as agent for the Secured Parties shall receive good funds for such proceeds. For purposes of computing interest, the Collateral Agent shall treat deposited checks, drafts and other items as collected in accordance with the Collateral Agent's normal availability schedule, but in doing so the Collateral Agent is not agreeing that such funds have in fact been paid, nor is the Collateral Agent as agent for the Secured Parties waiving any right it may have to charge back returned items to the Debtor and to collect interest on such charged-back items. Funds placed in the Collection Account shall be held by the Collateral Agent as agent for the Secured Parties as security for the Obligations. These proceeds shall be deposited in precisely the form received, except for the endorsement of the Debtor where necessary to permit collection of items, which endorsement the Debtor agrees to make, and which endorsement the Collateral Agent is also hereby authorized to make on behalf of the Debtor. Pending such deposit, the Debtor agrees that it will not commingle any such checks, drafts, cash or other remittances with any funds or other property of the Debtor but will hold them separate and apart therefrom, and upon an express trust for the Collateral Agent until deposit thereof is made in the Collection Account. The Collateral Agent as agent for the Secured Parties will from time to time apply the funds on deposit in the Collection Account against the Obligations in such order of application as is required by the Intercreditor Agreement. SECTION 7 - POWER OF ATTORNEY Effective upon the occurrence and during the continuance of any Event of Default, the Debtor hereby appoints the Collateral Agent and the Collateral Agent's designee as the Debtor's attorney-in-fact, with full power of substitution: (a) to endorse the Debtor's name on any checks, notes, acceptances, money orders, or other forms of payment or security that come into the Collateral Agent's or any Secured Party's possession; (b) to sign the Debtor's name on any invoice, bill of lading, warehouse receipt or other negotiable or non-negotiable Document constituting Collateral, on drafts against customers, on assignments of Accounts, on notices of assignment, financing statements and other public records and to file any such financing statements by electronic means with or without a signature as authorized or required by applicable law or filing procedure; (c) to execute loss claims and other applications for payment of benefits under any insurance policy covering any of the Collateral in the name of the Debtor or the Collateral Agent, to receive all monies and endorse drafts, checks, and other instruments for the payment of any proceeds of any insurance or in order to collect any return of unearned premiums, (d) to notify the post office authorities to change the address for delivery of the Debtor's mail to an address designated by the Collateral Agent and to receive, open and dispose of all mail addressed to the Debtor; (e) to send requests for verification of Accounts to customers -15-

or Account Debtors; (f) to complete in the Debtor's name or the Collateral Agent's name, any order, sale or transaction, obtain the necessary Documents in connection therewith, and collect the proceeds thereof; (g) to clear Inventory through customs in the Debtor's name, the Collateral Agent's name or the name of the Collateral Agent's designee, and to sign and deliver to customs officials powers of attorney in the Debtor's name for such purpose; (h) to the extent that the Debtor's authorization given in Section 5.1(d) of this Security Agreement is not sufficient (which authorization in Section 5.1(d) is effective, and which powers under Section 5.1(d) may be exercised by the Collateral Agent, before the occurrence of an Event of Default), to file such financing statements with respect to this Security Agreement, with or without the Debtor's signature, or to file a photocopy of this Security Agreement in substitution for a financing statement, as the Collateral Agent may deem appropriate and to execute in the Debtor's name such financing statements and amendments thereto and continuation statements which may require the Debtor's signature; and (i) to do all things necessary to carry out the terms of this Security Agreement. The Collateral Agent shall not be obligated to do any of the acts or exercise any of the powers hereinabove authorized, but, if the Collateral Agent elects to do any such act or exercise any such power, unless the Collateral Agent is guilty of gross negligence or willful misconduct in the exercise of such power, it shall not be accountable to the Debtor for more than it actually receives as a result of such exercise of power, and, in any event, none of the Collateral Agent or any of the Secured Parties, nor any of their respective attorneys, will be liable for any acts or omissions or for any error of judgment or mistake of fact or law except for their gross negligence or willful misconduct. This appointment shall be deemed a power coupled with an interest, shall be irrevocable, and shall not terminate until the Obligations have been fully satisfied, the Credit Agreement has been terminated and the Notes (as defined in the Note Agreement) have been paid in full under the Note Agreement. The Debtor hereby ratifies and approves all acts of such attorney-in-fact. SECTION 8 - NO LIABILITY (a) The Debtor assumes all responsibility and liability arising from or relating to the use, sale, license or other disposition of the Collateral. The Obligations shall not be affected by any failure of the Collateral Agent or any of the Secured Parties to take any steps to perfect the Collateral Agent's Liens or to collect or realize upon the Collateral, nor shall loss of or damage to the Collateral release the Debtor from any of the Obligations. Following the occurrence and during the continuation of any Event of Default, the Collateral Agent may (but shall not be required to), without notice to or consent from the Debtor, sue upon or otherwise collect, extend the time for payment of, modify or amend the terms of, compromise or settle for cash, credit, or otherwise upon any terms, grant other indulgences, extensions, renewals, compositions, or releases, and take or omit to take any other action with respect to the Collateral, any security therefor, any agreement relating thereto, any insurance applicable thereto, or any Person liable directly or indirectly in connection with any of the foregoing, without discharging or otherwise affecting the liability of the Debtor for the Obligations, or any other agreement now or hereafter existing between the Collateral Agent and/or any Secured Party and the Debtor. (b) It is expressly agreed by the Debtor that, anything herein to the contrary notwithstanding, the Debtor shall remain liable under each of its contracts and each of its licenses to observe and perform all the conditions and obligations to be observed and performed by it thereunder. None of the Collateral Agent or any of the Secured Parties shall have any -16-

obligation or liability under any contract or license by reason of or arising out of this Security Agreement or the granting herein of a Lien thereon or the receipt by the Collateral Agent or any Secured Party of any payment relating to any contract or license pursuant hereto. None of the Collateral Agent or any Secured Party shall be required or obligated in any manner to perform or fulfill any of the obligations of the Debtor under or pursuant to any contract or license, or to make any payment, or to make any inquiry as to the nature or the sufficiency of any payment received by it or the sufficiency of any performance by any party under any contract or license, or to present or file any claims, or to take any action to collect or enforce any performance or the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times. (c) The Collateral Agent may at any time after any Event of Default shall have occurred and be continuing (or if any rights of set-off (other than set-offs against an Account arising under the contract giving rise to the same Account) or contra accounts may be asserted with respect to the following), without prior notice to the Debtor, notify Account Debtors, and other Persons obligated on the Collateral that the Collateral Agent has a security interest therein, and that payments shall be made directly to the Collateral Agent, for the benefit of the Secured Parties. Upon the request of the Collateral Agent, the Debtor shall so notify Account Debtors, and other Persons obligated on Collateral. Once any such notice has been given to any Account Debtor or other Person obligated on the Collateral, the Debtor shall not give any contrary instructions to such Account Debtor or other Person without the Collateral Agent's prior written consent. (d) After the occurrence and during the continuance of any Event of Default, the Collateral Agent may at any time in the Collateral Agent's own name or in the name of the Debtor communicate with Account Debtors, parties to contracts and agreements to which the Debtor is a party, and obligors in respect of Instruments to verify with such Persons, to the Collateral Agent's satisfaction, the existence, amount and terms of Accounts, contracts and agreements, payment intangibles, Instruments or Chattel Paper. If any Event of Default shall have occurred and be continuing, the Debtor, at its own expense, shall cause the independent certified public accountants then engaged by the Debtor to prepare and deliver to the Collateral Agent and each of the Secured Parties at any time and from time to time promptly upon the Collateral Agent's request the following reports with respect to the Debtor: (i) a reconciliation of all Accounts; (ii) an aging of all Accounts; (iii) trial balances; and (iv) a test verification of such Accounts as the Collateral Agent may request. The Debtor, at its own expense, shall deliver to the Collateral Agent the results of each physical verification, if any, which the Debtor may in its discretion have made, or caused any other Person to have made on its behalf, of all or any portion of its Inventory. (e) The Collateral Agent shall use reasonable care with respect to the Collateral in its possession or under its control. The Collateral Agent shall not have any other duty as to any Collateral in its possession or control or in the possession or control of any agent or nominee of the Collateral Agent, or any income thereon or as to the preservation of rights against prior parties or any other rights pertaining thereto. -17-

SECTION 9 - DEFAULT AND REMEDIES (a) In addition to all other rights and remedies granted to it under this Security Agreement, the Credit Agreement, the other Loan Documents, the Note Agreement, and under any other instrument or agreement securing, evidencing or relating to any of the Obligations, upon the occurrence of any Event of Default, the Collateral Agent, as agent for the Secured Parties, may, subject to the provisions of the Intercreditor Agreement, exercise all rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing, the Debtor expressly agrees that in any such event the Collateral Agent, without demand of performance or other demand, advertisement or notice of any kind (except the notice specified below of time and place of public or private sale) to or upon the Debtor or any other Person (all and each of which demands, advertisements and notices are hereby expressly waived to the maximum extent permitted by the UCC and other applicable law), may forthwith enter upon the premises of the Debtor where any Collateral is located through self-help, without judicial process, without first obtaining a final judgment or giving the Debtor or any other Person notice and opportunity for a hearing on the Collateral Agent's claim or action and may collect, receive, assemble, process, appropriate and realize upon the Collateral, or any part thereof, and may forthwith sell, lease, license, assign, give an option or options to purchase, or sell or otherwise dispose of and deliver the Collateral (or contract to do so), or any part thereof, in one or more parcels at a public or private sale or sales, at any exchange at such prices as it may deem acceptable, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent shall have the right upon any such public sale or sales and, to the extent permitted by law, upon any such private sale or sales, to purchase for the benefit of the Collateral Agent and the Secured Parties the whole or any part of the Collateral so sold, free of any right or equity of redemption, which equity of redemption the Debtor hereby releases. Such sales may be adjourned and continued from time to time with or without notice. The Collateral Agent shall have the right to conduct such sales on the Debtor's premises or elsewhere and shall have the right to use the Debtor's premises without charge for such time or times as the Collateral Agent deems necessary or advisable. Expenses of retaking, holding, preparing for sale, selling and the like shall include the reasonable attorneys' fees and legal expenses of the Collateral Agent and the Secured Parties, and each of them. (b) After the occurrence and during the continuance of any Event of Default, the Debtor further agrees, at the Collateral Agent's request, to assemble the Collateral and make it available to the Collateral Agent at a place or places designated by the Collateral Agent which are reasonably convenient to the Collateral Agent and the Debtor, whether at the Debtor's premises or elsewhere. Until the Collateral Agent is able to effect a sale, lease, or other disposition of Collateral, the Collateral Agent shall have the right to hold or use Collateral, or any part thereof, to the extent that it deems appropriate for the purpose of preserving the Collateral or its value or for any other purpose deemed appropriate by the Collateral Agent. The Collateral Agent shall have no obligation to the Debtor to maintain or preserve the rights of the Debtor as against third parties with respect to Collateral while Collateral is in the possession of the Collateral Agent. The Collateral Agent may, if it so elects, seek the appointment of a receiver or keeper to take possession of Collateral and to enforce any of the Collateral Agent's remedies (for the benefit of the Collateral Agent and the Secured Parties), with respect to such appointment without prior notice or hearing as to such appointment. The Collateral Agent shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale -18-

to the Obligations in such order of application as is required by the Intercreditor Agreement, and only after so paying over such net proceeds, and after the payment by the Collateral Agent of any other amount required by any provision of law, need the Collateral Agent account for the surplus, if any, to the Debtor. To the maximum extent permitted by applicable law, the Debtor waives all claims, damages, and demands against the Collateral Agent and each Secured Party arising out of the repossession, retention or sale of the Collateral except such as arise solely out of the gross negligence or willful misconduct of the Collateral Agent or any Secured Party as finally determined by a court of competent jurisdiction. The Collateral Agent will give the Debtor reasonable notice of the time and place of any public sale of the Collateral or any part thereof or of the time after which any private sale or any other intended disposition thereof is to be made. The Debtor and the Collateral Agent agree that the requirements of reasonable notice shall be met if such notice is given to the Debtor at the address of the Debtor specified in Section 10.2 of this Security Agreement (or such other address that the Debtor may provide to the Collateral Agent in writing) at least ten (10) days before the time of the sale or disposition, but nothing contained herein shall be construed to mean that any other notice or a shorter period of time does not constitute reasonable notice for the sale of the Collateral or any part thereof. The Debtor shall remain liable for any deficiency if the proceeds of any sale or disposition of the Collateral are insufficient to pay all Obligations, including any attorneys' fees or other expenses incurred by the Collateral Agent or any Secured Party to collect such deficiency. (c) After the occurrence and during the continuance of any Event of Default, the Collateral Agent shall have the right to enter upon the premises of the Debtor at any time for the purpose of reducing to possession the Accounts (including Chattel Paper) and all cash or non-cash proceeds thereof, for the purpose of taking possession of and using the current version of the Debtor's accounts receivable computer software, and/or for the purpose of inspecting the Inventory and Equipment and inspecting and/or auditing the books, records and procedures of the Debtor. The Collateral Agent may deduct its expenses in collecting the Accounts from the proceeds applicable to the Obligations. Such expenses shall include, without limitation, the costs of posting transactions to the books of the Debtor and performing such other bookkeeping and accounting tasks as the Collateral Agent may deem appropriate to collect any Account. (d) Except as otherwise specifically provided herein, the Debtor hereby waives presentment, demand, protest or any notice (to the maximum extent permitted by applicable law) of any kind in connection with this Security Agreement or any Collateral. (e) For the purpose of enabling the Collateral Agent to exercise rights and remedies under this Section 9 (including, without limiting the terms of this Section, in order to take possession of, hold, preserve, process, assemble, prepare for sale, market for sale, sell or otherwise dispose of Collateral) at such time as the Collateral Agent shall be lawfully entitled to exercise such rights and remedies, the Debtor hereby grants to the Collateral Agent, for the benefit of the Collateral Agent and the Secured Parties, an irrevocable, nonexclusive license (exercisable without payment of royalty or other compensation to the Debtor) to use, license or sublicense any Proprietary Rights now owned or hereafter acquired by the Debtor, and wherever the same may be located, and including in such license access to all media in which any of the licensed items may be recorded or stored and to all computer software and programs used for the compilation or printout thereof. -19-

NOTWITHSTANDING THE FOREGOING, NO SECURED PARTY SHALL EXERCISE, OR ATTEMPT TO EXERCISE, ANY RIGHT OF SET-OFF, BANKER'S LIEN, OR THE LIKE, AGAINST ANY DEPOSIT ACCOUNT OR PROPERTY OF THE COMPANY OR ANY OF ITS SUBSIDIARIES HELD OR MAINTAINED BY THE SECURED PARTY WITHOUT THE PRIOR WRITTEN CONSENT OF THE COLLATERAL AGENT AND THE REQUIRED SECURED PARTIES. Section 3.2. Representations and Warranties. (a) Each of the Secured Parties represents and warrants to the other parties hereto that: (1) It (i) is either (x) a corporation duly organized, existing and in good standing under the laws of the jurisdiction of its incorporation or (y) a national banking association duly incorporated and existing under the laws of the United States of America or a state-licensed branch of a foreign bank, and (ii) has all requisite power (corporate or otherwise) to own its property and conduct its business as now conducted and as presently contemplated. (2) The execution, delivery and performance by such Secured Party of this Agreement has been authorized by all necessary proceedings (corporate or otherwise) and does not and will not contravene any provision of law, its charter or by-laws or any 7

amendment thereof, or of any indenture, agreement, instrument or undertaking binding upon such Secured Party. (3) The execution, delivery and performance by such Secured Party of this Agreement will result in a valid and legally binding obligation of such Secured Party enforceable in accordance with its terms. (b) The Collateral Agent hereby represents and warrants as of the date hereof that: (1) Collateral Agent is a state banking corporation validly existing and in good standing under the laws of the State of Virginia. (2) Collateral Agent has full power, authority and legal right under the laws of Virginia pertaining to its banking powers to execute, deliver, and perform this Agreement and has taken all necessary action to authorize the execution, delivery and performance by it of this Agreement. (3) Execution, delivery and performance by the Collateral Agent of this Agreement will not contravene any law, rule or regulation of the United States or any United States governmental authority or agency regulating the Collateral Agent's banking activities or any judgment or order applicable to or binding on the Collateral Agent and will not contravene or result in any breach of, or constitute a default under, the Collateral Agent's constitutive documents or the provision of any indenture, mortgage, contract or other agreement to which it is a party or by which it or any of its properties is bound. (4) Execution, delivery and performance by the Collateral Agent of this Agreement will not require the authorization, consent, or approval of, the giving of notice to, the filing or registration with, or the taking of any other action in respect of, any United States governmental authority or agency regulating the banking activities of the Collateral Agent. (5) This Agreement has been duly executed and delivered by the Collateral Agent and constitutes the legal, valid, and binding agreement of the Collateral Agent, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent conveyance and similar laws affecting creditors' rights generally, and general principles of equity (regardless of whether the application of such principles is considered in a proceeding in equity or at law). Section 3.3. Cooperation; Accountings. Each of the parties hereto will, upon the reasonable request of another party, from time to time execute and deliver or cause to be executed and delivered such further instruments, and do and cause to be done such further acts as may be necessary or proper to carry out more effectively the provisions of this Agreement. The Secured Parties agree to provide to each other upon reasonable request a statement of all payments received in respect of Secured Obligations. Section 3.4. Termination of Credit Agreement and Note Agreement; Amendments to Credit Agreement or Note Agreement. (a) Upon final payment in full of all Secured Obligations owing to any Secured Party, and, in the case of BB&T-VA or any Additional Creditors under the 8

Qualified Replacement Credit Agreement, after the termination of BB&T-VA's Revolving Commitment (as defined in the Credit Agreement) or such Additional Creditors' commitment to lend under the Qualified Replacement Credit Agreement, as applicable, such Secured Party shall cease to be a party to this Agreement; provided, however, if all or any part of any payments to such Secured Party are invalidated or set aside or required to be paid or repaid to any Person in any Bankruptcy Proceeding or otherwise (including, without limitation, any payment required to be made by such Secured Party to one or more of the other Secured Parties pursuant to (S)6.15 hereof), then this Agreement shall be renewed as of such date and shall thereafter continue in full force and effect to the extent of the Secured Obligations so invalidated, set aside, paid or repaid. (b) The Secured Parties agree with each other that neither (i) the Noteholders in the case of the Note Agreement, (ii) BB&T-VA in the case of the Credit Agreement, and (iii) the relevant Additional Creditors party to any Qualified Replacement Credit Agreement, if any, will effect or agree to any waiver, amendment, restatement, extension or modification to the Note Agreement, the Credit Agreement, or the Qualified Replacement Credit Agreement, if any, as the case may be, which shall have the effect of (1) increasing the aggregate principal amount of indebtedness owed (or commitments to lend) thereunder other than additional Funded Debt (as defined in the Note Agreement) which the Company is permitted to incur under the relevant terms and provisions of the Note Agreement without giving effect to any amendment thereto after the date hereof, (2) shortening the scheduled amortization of the indebtedness (excluding the Term Debt) issued thereunder from the amortization in effect as of the date hereof or (3) (A) in the case of the Note Agreement, increase the rate of interest borne by the Notes by more than 100 basis points per annum (other than the imposition of the relevant default rate of interest; provided that there shall be no increase in any such default rate from the rate imposed on the date hereof), (B) in the case of the Credit Agreement, increase the interest rate on the Revolving Debt by increasing any margin over the LIBOR rate (as defined in the Credit Agreement) assessed with respect to the Revolving Debt by more than 100 basis points per annum from such margins which are in effect on the date hereof, and with respect to any interest rate or percentage fee assessed with respect to the Revolving Debt determined without reference to such LIBOR rate, no increase in such interest rate or percentage fee shall be made by an amount which exceeds 100 basis points per annum from such rate or percentage fee in effect on the date hereof (other than the imposition of the relevant default rate of interest; provided that there shall be no increase in any such default rate from the rate imposed on the date hereof), and (C) in the case of any Qualified Replacement Credit Agreement, increases the interest rate thereon which would result in an interest rate in excess of such rate which is or would have been permitted under clause (B) above if the Additional Funded Debt thereunder was considered to be Revolving Debt under the Credit Agreement, in each case without the prior written approval of BB&T-VA (or, if applicable, the Additional Creditors under any Qualified Replacement Credit Agreement) and the holders of at least 66-2/3% in principal amount of the Notes at the time outstanding. Section 3.5. Additional Creditor. Additional Creditors may, upon compliance with the relevant provisions of the Note Agreement, the Credit Agreement and any outstanding Additional Facility, become "Secured Parties" hereunder by executing and delivering to the Collateral Agent and to each of the then existing Secured Parties (a) a joinder agreement in the form attached hereto as Exhibit C and (b) a copy of the Additional Facility or Additional Facilities to which such Person is a party. Accordingly, upon the execution and delivery of any such copy of this Agreement by any such Person, such Person, shall, upon delivery thereof to the 9

then existing Secured Parties, thereafter become a Secured Party for all purposes of this Agreement. SECTION 4 Appointment and Authorization Of Collateral Agent. (a) Each Secured Party hereby irrevocably designates and appoints Branch Banking and Trust Company of Virginia as the Collateral Agent of such Secured Party under this Agreement and the Collateral Documents, and each Secured Party hereby irrevocably authorizes Branch Banking and Trust Company of Virginia as the Collateral Agent for such Secured Party to execute and enter into each of the Collateral Documents and all other instruments relating to said Collateral Documents and (i) to take action on its behalf and exercise such powers and use such discretion as are expressly permitted hereunder and under the Collateral Documents and all instruments relating hereto and thereto and (ii) to exercise such powers and perform such duties as are, in each case, expressly delegated to the Collateral Agent by the terms hereof and thereof together with such other powers and discretion as are reasonably incidental hereto and thereto. (b) Notwithstanding any provision to the contrary elsewhere in this Agreement or the Collateral Documents, the Collateral Agent shall not have any duties or responsibilities except those expressly set forth herein or therein or any fiduciary relationship with any Secured Party, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any Collateral Document or otherwise exist against the Collateral Agent. SECTION 5 Agency Provisions. Section 5.1. Delegation of Duties. The Collateral Agent may exercise its powers and execute any of its duties under this Agreement and the Collateral Documents by or through employees, agents or attorneys-in-fact and shall be entitled to take and to rely on advice of counsel concerning all matters pertaining to such powers and duties. The Collateral Agent shall not be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care. The Collateral Agent may utilize the services of such Persons as the Collateral Agent in its sole discretion may determine, and all reasonable fees and expenses of such Persons shall be borne by the Company. Section 5.2. Exculpatory Provisions. Neither the Collateral Agent nor any of the Collateral Agent's officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be (a) liable for any action taken or omitted to be taken by it or such Person under or in connection with this Agreement or any Collateral Document or any Collateral (except for its or such Person's own gross negligence or willful misconduct), or (b) responsible in any manner to any of the Secured Parties for any recitals, statements, representations or warranties made by the Grantors, any officer thereof or any other Person contained in, or made or deemed made in connection with, the Credit Agreement, the Note Agreement, any Additional Facility Document or any Collateral Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Agreement, the Credit Agreement, the Note Agreement, any Additional Facility Document or any Collateral Document, or for the due execution, legality, value, validity, effectiveness, genuineness, enforceability or sufficiency of the Credit Agreement, the Note Agreement, any Additional Facility Document or any Collateral Document or any other document or instrument 10

furnished pursuant thereto or of any of the Collateral or for any failure of any Grantor to perform its obligations under such documents. The Collateral Agent shall be under no obligation to the Secured Parties to ascertain or to inquire as to the observance or performance of any of the agreements contained in, statements made in, or conditions of the Credit Agreement, the Note Agreement, any Additional Facility Document or any Collateral Document or to inspect the property (including the books and records) of the Grantors. Section 5.3. Reliance by Collateral Agent. The Collateral Agent shall be entitled to rely, and shall be fully protected and shall incur no liability in acting and relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document or conversation reasonably believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Grantors), independent accountants and other experts selected by the Collateral Agent. Without limiting the generality of the foregoing, the Collateral Agent may treat the payee of any Revolving and Noteholder Debt or any Additional Facility Note as the registered holder thereof until it receives notice or otherwise has actual knowledge that such payee is no longer the registered holder of such Revolving and Noteholder Debt or Additional Facility Note. Notwithstanding anything to the contrary contained herein or in any Collateral Document, the Collateral Agent shall be fully justified in failing or refusing to take action under this Agreement or the Collateral Documents (including, without limitation, the exercise of any rights or remedies under, or the entering into of any agreement amending, modifying, supplementing, waiving any provision of, or the giving of consent pursuant to, any of the Collateral Documents) unless it shall first receive instructions of the Required Secured Parties as is contemplated by (S)6 hereof and it shall first be indemnified to its reasonable satisfaction by the relevant Secured Parties against any and all liability and expense which may be incurred by it by reason of taking, continuing to take or refraining from taking any such action. The Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the Collateral Documents in accordance with the provisions of (S)6.5 hereof and in accordance with written instructions of the Required Secured Parties pursuant to (S)6.3 hereof, and such instructions and any action taken or failure to act pursuant thereto shall be binding upon all the relevant Secured Parties. Section 5.4. Knowledge or Notice of Default, Event of Default. The Collateral Agent shall not be deemed to have actual, constructive, direct or indirect knowledge or notice of the occurrence of any Default or Event of Default unless and until the Collateral Agent has received written notice from a Secured Party or the Company referring to the Credit Agreement, the Note Agreement, the Additional Facility Documents, or the Collateral Documents, describing such Default or Event of Default and stating that it is a "notice of default" or a "notice of event of default", setting forth in reasonable detail the facts and circumstances thereof and stating that the Collateral Agent may rely on such notice without further inquiry; provided that if BB&T-VA (or any Additional Creditor under a Qualified Replacement Credit Agreement) is the Collateral Agent hereunder, the Collateral Agent shall be deemed to have actual knowledge and notice of the occurrence of any Default or Event of Default (as defined in the Credit Agreement or Qualified Replacement Credit Agreement) under the Credit Agreement or Qualified Replacement Credit Agreement if BB&T-VA (or such Additional Creditor) has actual knowledge of such Default or Event of Default or has declared an Event of Default under the Credit Agreement or Qualified Replacement Credit Agreement. The Collateral Agent shall have 11

no obligation or duty prior to or after receiving any such notice to inquire whether a Default or Event of Default has in fact occurred and shall be entitled to rely, and shall be fully protected in so relying, on any such notice furnished to it. Section 5.5. Non-Reliance on Collateral Agent and Other Secured Parties. Each Secured Party expressly acknowledges that, except as expressly set forth in this Agreement, neither the Collateral Agent nor any of the Collateral Agent's officers, directors, employees, agents, attorneys-in-fact or Affiliates has made any representations or warranties to it and that no act by the Collateral Agent hereafter taken, including any review of the affairs of the Grantors, shall be deemed to constitute any representation or warranty by the Collateral Agent to any Secured Party. Each Secured Party represents that it has, independently and without reliance upon the Collateral Agent or any other Secured Party, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and credit-worthiness of the Grantors and made its own decision to enter into this Agreement, the Credit Agreement, the Note Agreement, any Additional Facility Document or any Collateral Document. Each Secured Party also represents that it will, independently and without reliance upon the Collateral Agent or any other Secured Party, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under the Credit Agreement, the Note Agreement, any Additional Facility Document or any Collateral Document and this Agreement, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and credit-worthiness of the Grantors. Except for notices, reports and other documents expressly required to be furnished to the Secured Parties by the Collateral Agent hereunder, the Collateral Agent shall not have any duty or responsibility to provide the Secured Parties with any credit or other information concerning the business, operations, property, financial and other condition or credit-worthiness of the Grantors which may come into the possession of the Collateral Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates. Section 5.6. Indemnification. The Secured Parties agree to indemnify the Collateral Agent in its capacity as such (to the extent not reimbursed by the Company, but without limiting any obligation of the Company to do so) ratably in accordance with the Secured Parties' Pro Rata Shares, against, and hold the Collateral Agent harmless from, any and all liabilities, obligations, losses, claims, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever, which may be imposed on, incurred by, or asserted against the Collateral Agent, in any way relating to or arising out of this Agreement or any Collateral Document or the transactions contemplated hereby or thereby or any action taken or omitted by the Collateral Agent in connection with any of the foregoing; provided that no Secured Party shall be liable to the Collateral Agent for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements to the extent they are found by a final decision of a court of competent jurisdiction to have resulted from the Collateral Agent's gross negligence or willful misconduct. The agreements in this (S)5.6 shall survive the payment of the Secured Obligations. Section 5.7. Collateral Agent in Its Individual Capacity. BB&T-VA and its Affiliates may make loans to and generally engage in any kind of business with the Company or any other Grantor as though such Person was not the Collateral Agent hereunder and without any duty to 12

account therefor to the Secured Parties. With respect to any Revolving and Noteholder Debt issued to it and advances made by it under the Credit Agreement, if any, BB&T-VA shall have the same rights and powers under this Agreement as any Secured Party and may exercise the same as though it were not the Collateral Agent, and the terms "Secured Party" and "Secured Parties" shall include BB&T-VA in its individual capacity. Any Additional Creditor which succeeds BB&T-VA as Collateral Agent shall have the same rights as BB&T-VA under this Section 5.7 with respect to Debt issued to it and advances made by it under the Additional Facilities. Section 5.8. Successor Collateral Agent. (a) The Collateral Agent may resign at any time upon thirty days' notice to the Secured Parties and the Company and may be removed at any time, with or without cause, by the Required Secured Parties by written notice delivered to the Company, the Collateral Agent and the Secured Parties. If the Collateral Agent is also BB&T-VA, or an Additional Creditor under the Qualified Replacement Credit Agreement, then the Noteholders may remove the Collateral Agent for a material breach of its obligations under this Agreement at any time upon a vote of the holders of 75% or more of the aggregate principal amount of outstanding Notes. After any resignation or removal hereunder of the Collateral Agent, the provisions of this (S)5 shall continue to inure to its benefit as to any actions taken or omitted to be taken by it in connection with its role as Collateral Agent hereunder while it was the Collateral Agent under this Agreement and it shall be entitled to be paid promptly when due any amounts owing to it pursuant to (S)5.6. (b) Upon receiving notice of any such resignation or removal, a successor Collateral Agent shall be appointed by the Required Secured Parties; provided, however, that such successor Collateral Agent shall be (i) a bank or trust company having a combined capital and surplus of at least $500,000,000, subject to supervision or examination by a federal or state banking authority; and (ii) authorized under the laws of the jurisdiction of its incorporation or organization to assume the functions of the Collateral Agent. If the appointment of such successor shall not have become effective (as hereafter provided) (x) within such thirty day period after the Collateral Agent's notice of resignation or (y) upon removal of the Collateral Agent, then the Collateral Agent may assign the Liens and its duties hereunder and under the Collateral Documents to the Secured Parties, as their interests may appear, and in such case all references herein to "Collateral Agent" shall be deemed to refer to the "Required Secured Parties." Any Secured Party may petition a court of competent jurisdiction for the appointment of a successor Collateral Agent. Such court shall, after such notice as it may deem proper, appoint a successor Collateral Agent meeting the qualifications specified in this (S)5.8(b). The Secured Parties hereby consent to such petition and appointment so long as such criteria are met. (c) The resignation or removal of a Collateral Agent shall become effective upon the execution and delivery of such documents or instruments as are necessary to transfer the rights and obligations of the Collateral Agent under the Collateral Documents, including, without limitation, the delivery and recordation of all amendments, instruments, deed of trusts, financing statements, continuation statements and other documents necessary to maintain the perfection of the security interests held by the Collateral Agent hereunder. Copies of each such document or instrument shall be delivered to all Secured Parties. Subject to the foregoing provisions of this (S)5.8(c), the appointment of a successor Collateral Agent pursuant to this (S)5.8 13

shall become effective upon the acceptance of the appointment as Collateral Agent hereunder by a successor Collateral Agent. Upon such effective appointment, the successor Collateral Agent shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent and the retiring Collateral Agent shall be discharged from its rights, powers, privileges and duties under this Agreement and the other Collateral Documents; provided, however, that the provisions of this (S)5 shall continue to inure to the retiring Collateral Agent's benefit as to any actions taken or omitted to be taken by it in connection with its role as Collateral Agent hereunder while it was the Collateral Agent under this Agreement. SECTION 6 Actions By The Collateral Agent. Section 6.1. Duties and Obligations. The duties and obligations of the Collateral Agent are only those set forth in this Agreement and in the Collateral Documents. Section 6.2. Notification of Default. If the Collateral Agent has been notified in a writing conforming to the requirements of (S)5.4 by any Secured Party that a Default, an Event of Default or a Special Event of Default has occurred, the Collateral Agent shall furnish to the Secured Parties a copy of such written notice and may, but is under no obligation to, furnish to the Company a copy of the notice received by the Collateral Agent and a copy of the Collateral Agent's notice to the Secured Parties. The failure of any Secured Party having knowledge of the occurrence of a Default, an Event of Default or a Special Event of Default to notify the Collateral Agent or any Secured Party of such occurrence, however, does not constitute a waiver of such Default, Event of Default or Special Event of Default by the Secured Parties. Upon receipt of a notice conforming to the requirements of (S)5.4 from a Secured Party of the occurrence of an Event of Default or a Special Event of Default, the Collateral Agent shall (in addition to the action required by the first sentence of this (S)6.2) promptly (and in any event no later than three Business Days after receipt of such notice) issue its Notice of Default to all Secured Parties. Such Notice of Default shall indicate the nature of such Event of Default or Special Event of Default. The Notice of Default may contain a recommendation of actions to be taken by the Secured Parties and/or request instructions from the Secured Parties and shall specify the date on which responses are due in order to be timely within (S)6.4 hereof. Section 6.3. Exercise of Remedies. Except as otherwise provided in (S)6.5, the Collateral Agent shall take only such actions and exercise only such remedies under the Collateral Documents as are approved in written instructions delivered to the Collateral Agent and signed by the Required Secured Parties required under (S)6.4. In the event that the Collateral Agent shall determine in good faith that taking the actions specified in such instructions is contrary to law, it may refrain (and shall be fully protected in so refraining) from taking such action and shall immediately give notice of such fact to each of the Secured Parties. In the event that instructions received by the Collateral Agent are in its good faith judgment ambiguous or conflict with other instructions received by the Collateral Agent, the Collateral Agent (a) shall promptly notify the Secured Parties of such ambiguity or conflict and request clarifying instructions, and (b) may either (1) delay taking any such action or exercising any such remedy pending the receipt of such clarifying instructions (and shall be fully protected in so delaying) or (2) take such actions as it is entitled under (S)6.5. Section 6.4. Instructions from Secured Parties. 14

Notwithstanding anything express or implied to the contrary in any Collateral Document: (a) remedies and other actions to be taken under the Collateral Documents or applicable law with respect to the Collateral shall be directed by the Required Secured Parties; and (b) if any Secured Party does not respond in a timely manner to any notice (including, without limitation, a Notice of Default) from the Collateral Agent or request for instructions within the time period specified by the Collateral Agent in such notice or request for instructions (which shall be a minimum of five Business Days), the Secured Obligations held by such Secured Party which would otherwise be included in a determination of Required Secured Parties shall not be included in the determination of Required Secured Parties for purposes of such notice or request for instructions. Any action taken or not taken without the vote of such Secured Party or Secured Parties under this (S)6.4 shall nevertheless be binding on such Secured Party or Secured Parties. Section 6.5. Emergency Actions. If the Collateral Agent has asked the Secured Parties for instruction and if the Required Secured Parties have not yet responded to such request, the Collateral Agent shall be authorized to take, but shall not be required to take and shall in no event have any liability for the taking or the failure to take, such actions (other than any action described or permitted under (S)6.7 hereof) with regard to a Default or Event of Default which the Collateral Agent, in good faith, believes to be reasonably required to promote and protect the interests of the Secured Parties and to preserve the value of the Collateral and shall give the Secured Parties appropriate notice of such action; provided that once instructions with respect to such request have been received by the Collateral Agent from the Required Secured Parties, the actions of the Collateral Agent shall be governed thereby and the Collateral Agent shall not take any further action which would be contrary thereto. Section 6.6. Changes to Collateral Documents. Any term of the Collateral Documents may be amended, and the performance or observance by the parties to a Collateral Document of any term of such Collateral Document may be waived (either generally or in a particular instance and either retroactively or prospectively) with the written consent of the Required Secured Parties. Section 6.7. Release of Collateral. The release of any Collateral by the Collateral Agent from the Lien of any Collateral Document shall be permitted with the written consent of all of the Secured Parties; provided, however, that if the Company or its Subsidiaries disposes of Collateral pursuant to a disposition that is permitted under both the Credit Agreement and the Note Agreement or Collateral is released as permitted under the terms of the Collateral Documents, then the written consent of the Secured Parties to the release by the Collateral Agent of such Collateral shall not be required. Section 6.8. Other Actions. The Collateral Agent shall have the right to take such actions, or omit to take such actions, hereunder and under the Collateral Documents not inconsistent with the written instructions of the Required Secured Parties delivered pursuant to (S)6.3 hereof or the terms of this Agreement, including actions the Collateral Agent deems necessary or appropriate to perfect or continue the perfection of the Liens on the Collateral for 15

the benefit of the Secured Parties. Except as otherwise provided by applicable law, the Collateral Agent shall have no duty as to any Collateral, the collection or protection of the Collateral or any income therefrom (including any duty to ascertain or take action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not the Collateral Agent has or is deemed to have knowledge of such matters), nor as to the preservation of rights against prior parties, nor as to the preservation of rights pertaining to the Collateral beyond the safe custody of any Collateral in the Collateral Agent's actual possession. Section 6.9. Cooperation. To the extent that the exercise of the rights, powers and remedies of the Collateral Agent in accordance with this Agreement requires that any action be taken by any Secured Party, such Secured Party shall take such action and cooperate with the Collateral Agent to ensure that the rights, powers and remedies of all Secured Parties are exercised in full. Section 6.10. Distribution of Proceeds of Collateral and Subsidiary Guaranties. (a) Upon any realization upon the Collateral, the Secured Parties agree that the proceeds thereof shall be applied (i) first, to the amounts owing to the Collateral Agent, solely in its capacity as Collateral Agent (or owing to the Secured Parties in such capacity if the Collateral Agent has resigned or has been removed), by the Grantors or the Secured Parties pursuant to this Agreement or the Collateral Documents; (ii) second, to reimburse the Secured Parties for any amounts paid under (S)5.6 hereof ratably; (iii) third, ratably to the payment of all amounts of accrued and unpaid interest (other than breakage costs or any Make-Whole Amount) which constitute Secured Obligations according to the aggregate amounts of such interest then owing to each Secured Party; (iv) fourth, ratably to all amounts of principal outstanding in respect of the Secured Obligations (including therein the unpaid reimbursement obligations relating to any drawings under letters of credit issued under the Credit Agreement or any Qualified Replacement Credit Agreement and, without duplication, in the manner set forth in the following paragraph the undrawn portion of any face amount of any such letters of credit) according to the aggregate amounts of such principal then owing to each Secured Party; (v) fifth, ratably to all other Secured Obligations then owing to the Secured Parties according to the aggregate amounts of such Secured Obligations then owing to each Secured Party; and (vi) sixth, the balance, if any, shall be returned to the Grantors or such other Persons as are entitled thereto. Any payment pursuant to this (S)6.10 with respect to the undrawn amount of any letters of credit shall be paid to the Collateral Agent for deposit in an account (the "Letter of Credit Collateral Account") to be held as collateral for the Secured Obligations and disposed of as provided herein. On each date after the occurrence of a Special Event of Default on which a payment is made to a beneficiary pursuant to a draw on a letter of credit, the Collateral Agent shall distribute from the Letter of Credit Collateral Account for application to the payment of the reimbursement obligation due to BB&T-VA or any Additional Creditors under the Qualified Replacement Credit Agreement, as applicable, with respect to such draw an amount equal to the product of (1) the amount then on deposit in the Letter of Credit Collateral Account, and (2) a fraction, the numerator of which is the amount of such draw and the denominator of which is the aggregate amount of all undrawn letters of credit with respect to the Revolving Debt (or, if applicable, revolving debt under the Qualified Replacement Credit Agreement) immediately prior to such draw. On each date on which a reduction in the aggregate amount of all undrawn 16

letters of credit occurs other than on account of a payment made to a beneficiary pursuant to a draw on a letter of credit, then the Collateral Agent shall distribute from the Letter of Credit Collateral Account an amount equal to the product of (1) the amount then on deposit in the Letter of Credit Collateral Account, and (2) a fraction, the numerator of which is the amount of such reduction in the aggregate amount of all undrawn letters of credit and the denominator of which is the aggregate amount of all undrawn letters of credit with respect to the Revolving Debt (or, if applicable, revolving debt under the Qualified Replacement Credit Agreement), immediately prior to such reduction, which amount shall be distributed as provided in the first paragraph of this (S)6.10. At such time as the aggregate amount of all undrawn letters of credit is reduced to zero, any amount remaining in the Letter of Credit Collateral Account, after the distribution therefrom as provided above, shall be distributed as provided in the first paragraph of this (S)6.10. (b) Upon the request of the Collateral Agent prior to any distribution under this (S)6.10, each Secured Party shall provide to the Collateral Agent certificates, in form and substance reasonably satisfactory to the Collateral Agent, setting forth the respective amounts referred to in (S)6.10(a) hereof which each such Secured Party believes it is entitled to receive. Section 6.11. Senior Preferential Payments and Special Trust Account. (a) After the receipt by each Secured Party of a Notice of Default pursuant to (S)6.2 stating that a Special Event of Default has occurred, all Senior Preferential Payments other than those payments received pursuant to subsection (b) of this (S)6.11 shall be delivered to the Collateral Agent for deposit into the Special Trust Account. (b) If (i) such Special Event of Default is waived by BB&T-VA, the Additional Creditors, and the Noteholders and if no other Event of Default has occurred and is continuing, (ii) such Special Event of Default is cured by the Company or by any amendment of the Credit Agreement, the Additional Facility Documents, or the Note Agreement, as the case may be, and if no other Event of Default has occurred and is continuing or (iii) any or all of the Secured Obligations have not been accelerated and the Required Secured Parties have not instructed the Collateral Agent to foreclose on a substantial portion of the Collateral, seek the appointment of a receiver, commence litigation against the Company, liquidate the Collateral, commence a Bankruptcy Proceeding against the Company, seize Collateral, or exercise other remedies of similar character prior to the 180th day following such Special Event of Default, the Collateral Agent thereupon shall return all amounts, together with their pro rata share of any interest earned thereon, held in the Special Trust Account representing payment of any Secured Obligations to the Secured Party initially entitled thereto, and no payments thereafter received by a Secured Party shall constitute a Senior Preferential Payment by reason of such cured or waived Special Event of Default. No payment returned to a Secured Party for which such Secured Party has been obligated to make a deposit into the Special Trust Account shall thereafter ever be characterized as a Senior Preferential Payment. (c) Each Secured Party agrees that upon the occurrence of a Special Event of Default it shall (i) promptly notify the Collateral Agent of the receipt of any Senior Preferential Payments, (ii) hold such amounts in trust for the Secured Parties and act as agent of the Secured Parties during the time any such amounts are held by it, and (iii) deliver promptly to the Collateral Agent such amounts for deposit into the Special Trust Account as soon as practicable. 17

(d) If the Secured Obligations have been accelerated or the Required Secured Parties have instructed the Collateral Agent to foreclose on a substantial portion of the Collateral, seek the appointment of a receiver, commence litigation against the Company, liquidate the Collateral, commence a Bankruptcy Proceeding against the Company, seize Collateral, or exercise other remedies of similar character, then all funds, together with interest earned thereon, held in the Special Trust Account and all subsequent Senior Preferential Payments shall be applied in accordance with the provisions of (S)6.10 above. Section 6.12. Authorized Investments. Any and all funds held by the Collateral Agent in its capacity as Collateral Agent, whether pursuant to any provision of this Agreement or any of the Collateral Documents, shall to the extent feasible within a reasonable time be invested by the Collateral Agent in Cash Equivalent Investments. Prior to making such investment or to the extent it is not feasible to invest such funds in Cash Equivalent Investments, the Collateral Agent shall hold any such funds in an interest bearing account. Any interest earned on such funds shall be disbursed to the Secured Parties in accordance with (S)6.10 or (S)6.11, as applicable. The Collateral Agent shall have no duty to place funds held and invested pursuant to this (S)6.12 in investments which provide a maximum return. The Collateral Agent shall not be responsible for any loss of any funds invested in accordance with this (S)6.12. Section 6.13. Restoration of Obligations. For the purposes of determining the amount of outstanding Secured Obligations, if any Secured Party is required to deposit any Senior Preferential Payment in the Special Trust Account, then the obligations intended to be satisfied by such Senior Preferential Payment shall be revived, as of the date of the deposit of such amount with the Collateral Agent, in the amount of such Senior Preferential Payment and such obligation shall continue in full force and effect (and, if applicable, bear interest from such deposit date at the non-default rate as provided in the Notes or in the Credit Agreement or in the Additional Facility Documents, as the case may be) as if such Secured Party had not received such payment. All such revived obligations shall be included as Secured Obligations for purposes of allocating any payments under (S)6.10 and for applying the definition of Required Secured Parties. If any such revived obligation shall not be allowed as a claim under the Bankruptcy Code due to the fact that the Senior Preferential Payment has in fact been made by the Company, the Secured Parties shall make such other equitable arrangements for the purchase and sale of participations in the Secured Obligations to effectuate the intent of this (S)6.13. Section 6.14. Bankruptcy, Preferences, etc. If any payment to a Secured Party is subsequently invalidated, declared to be fraudulent or preferential or set aside and is required to be repaid to a trustee, receiver or any other party under any bankruptcy law, state or Federal law, common law or equitable cause, and such Secured Party has previously made a deposit in respect of such payment into the Special Trust Account pursuant to (S)6.11, then the Collateral Agent shall distribute to such Secured Party proceeds from the Special Trust Account in an amount equal to such deposit or so much thereof as is affected by such events and if, due to previous disbursements to the Secured Parties pursuant to (S)6.11(d), the proceeds in the Special Trust Account are insufficient for such purpose, then each other Secured Party shall pay to such Secured Party upon demand an amount equal to a ratable portion of such disbursements of the deposit which was distributed to each such Secured Party according to the aggregate amounts so distributed to each such Secured Party. 18

Section 6.15. Sharing of Proceeds. If, despite the provisions of this Agreement, any Secured Party shall receive any payment or other recovery in excess of its portion of payments on account of the Secured Obligations to which it is then entitled in accordance with this Agreement, such Secured Party shall hold such payment or other recovery in trust for the benefit of the parties entitled thereto and promptly pay over or deliver such payment or other recovery to the Collateral Agent for application by the Collateral Agent in accordance with this Agreement. SECTION 7 Bankruptcy Proceedings. The following provisions shall apply during any Bankruptcy Proceeding of any Grantor: (a) The Collateral Agent shall represent all Secured Parties in connection with all matters directly relating to the Collateral, including without limitation, use, sale or lease of Collateral, use of cash collateral, relief from the automatic stay and adequate protection. The Collateral Agent shall act on the instructions of the Required Secured Parties; provided that such instructions by the Required Secured Parties shall not treat any Secured Party differently with respect to rights in the Collateral from any other Secured Party; and provided further that if action is required prior to the time such instructions are received or if the Required Secured Parties fail to give instructions with respect to any matter, the Collateral Agent shall be authorized to act, or refrain from acting, in accordance with (S)6.5 hereof. (b) Each Secured Party shall be free to act independently on any issue not directly relating to the Collateral, including without limitation, matters relating to appointment of a trustee, conversion of a case, filing of claims, and plans of reorganization. Each Secured Party shall give prior notice to the Collateral Agent of any such action to the extent that such notice is possible. If such prior notice is not given, such Secured Party shall give prompt notice following any such action. SECTION 8 Additional Agreements of Secured Parties. (a) BB&T-VA, in its capacity as the Lender under the Credit Agreement agrees that the Secured Parties, through their authorized representatives or agents, may (to the extent BB&T-VA has the right to restrict access to the Winchester Collateral) enter upon any real property constituting Winchester Collateral from time to time during normal business hours for the sole purpose of inspecting, repairing, removing, caring for, protecting or conducting a sale or sales of any or all of the Collateral if the Collateral Agent provides BB&T-VA notice prior to each entry (which shall not be less than two (2) business days except in the case of emergency). BB&T-VA further agrees that neither the Collateral Agent nor any Secured Party shall have any obligation or liability to BB&T-VA, except, however, that the Secured Parties shall promptly repair any damage to the Winchester Collateral caused by the removal, repair, sale or inspection and the Secured Parties shall be liable for, and shall indemnify, defend and hold the Collateral Agent and BB&T-VA harmless from the gross negligence or willful misconduct of their employees or agents in connection with such removal, repairs, sale or inspection. The Collateral Agent and the Secured Parties agree that neither the Collateral Agent nor BB&T-VA shall have any obligation or liability to preserve, protect, manage, maintain, safekeep or otherwise have any responsibility for the Collateral beyond the safe custody of any Collateral in any such Person's actual possession. 19

(b) The Collateral Agent agrees to use its best efforts to give to BB&T-VA, via certified mail, written notice prior to the exercise by the Collateral Agent of any of its rights or remedies against the Collateral at the address provided for in (S)10.2 below; provided, however, that any failure to so provide such notice shall have no effect on the ability of the Collateral Agent to exercise any of its rights or remedies against the Collateral. (c) BB&T-VA agrees to use its best efforts to give to the Secured Parties, via certified mail, written notice prior to the exercise by BB&T-VA of any of its rights or remedies against the Winchester Collateral at the address provided for in (S)10.2 below; provided, however, that any failure to so provide such notice shall have no effect on the ability of BB&T-VA to exercise any of its rights or remedies against the Winchester Collateral. (d) If the Collateral Agent takes possession of the Grantors' books and records included in the Collateral, the Collateral Agent shall provide BB&T-VA reasonable access to inspect and copy such books and records if BB&T-VA provides prior notice (which shall be not less than two (2) business days except in the case of emergency) and if such access is necessary to exercise its rights and remedies in the Winchester Collateral. (e) If the Collateral Agent or the Secured Parties receives any Winchester Collateral or any proceeds thereof or if BB&T-VA (in its capacity as lender of the Term Debt under the Credit Agreement) receives any Collateral or any proceeds thereof in which the Secured Parties have a prior perfected security interest, such party shall (i) notify the other party in writing of the nature of such receipt, the date of the receipt and the amount thereof; (ii) deduct from the proceeds received any costs or expenses (including attorneys' fees and expenses) incurred in connection with the acquisition of such proceeds; (iii) hold the remaining amount of such proceeds in trust for the benefit of the other party until paid over to the other party; and (iv) pay the remaining amount of such proceeds or deliver the applicable Collateral to the other party hereto promptly upon receipt thereof. If at any time payment, in whole or in part, of any Collateral or proceeds of Collateral distributed hereunder is rescinded or must otherwise be restored or returned as a preference, fraudulent conveyance or otherwise under any bankruptcy, insolvency or similar law, then each party receiving any portion of such proceeds agrees, upon demand, to return the portion of such proceeds it has received to the party responsible for restoring or returning such proceeds. (f) References to BB&T-VA in this Section 8 shall also refer to all Additional Creditors under the Qualified Replacement Credit Agreement if such Additional Creditors are also the holders of a Lien on the Winchester Collateral. SECTION 9 Miscellaneous. Section 9.1. Entire Agreement. This Agreement represents the entire Agreement among the Collateral Agent, the Secured Parties and the Grantors in respect of the subject matter hereof. Section 9.2. Notices. Notices hereunder shall be given to the Secured Parties at their addresses as set forth in the Note Agreement or the Credit Agreement or at such other address as may be designated by each in a written notice to the other parties hereto. 20

Section 9.3. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Collateral Agent and each of the Secured Parties and their respective successors and assigns, whether so expressed or not, and, in particular, shall inure to the benefit of and be enforceable by and against any future holder or holders of any Secured Obligations, and the term "Secured Party" shall include any such subsequent holder of Secured Obligations, wherever the context permits. Section 9.4. Consents, Amendment, Waivers. All amendments, waivers or consents of any provision of this Agreement shall be effective only if the same shall be in writing and signed by the Collateral Agent and all of the Secured Parties. Section 9.5. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without giving effect to any conflicts of law principles. Section 9.6. Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one Agreement, and any of the parties hereto may execute this Agreement by signing any such counterpart. Section 9.7. Sale of Interest. No Secured Party will sell, transfer or otherwise dispose of any interest in the Secured Obligations unless such purchaser or transferee shall agree, in writing, to be bound by the terms of this Agreement. Section 9.8. Severability. In case any one or more of the provisions contained in this Agreement shall be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions of this Agreement shall not in any way be affected or impaired thereby. Section 9.9. Expenses. In the event of any litigation to enforce this Agreement, the prevailing party shall be entitled to its reasonable attorney's fees (including the allocated costs of in-house counsel). Section 9.10. Term of Agreement. This Agreement shall terminate when all Secured Obligations are paid in full and such payments are not subject to any possibility of revocation or rescission and no Secured Party has any commitment to extend any additional credit constituting Secured Obligations under the terms of the Credit Agreement or any Qualified Replacement Credit Agreement, or when the Collateral Agent, BB&T-VA (if then a Secured Party) and all of the other Secured Parties mutually agree in a writing to terminate this Agreement, whichever occurs earlier. Section 9.11. Obligations Several. The obligations of the Secured Parties and the Collateral Agent hereunder are several. The failure of any Secured Party or the Collateral Agent to carry out its obligations hereunder shall not relieve any other Secured Party or the Collateral Agent of any obligation hereunder, nor shall any Secured Party or the Collateral Agent be responsible for the obligations of, or any action taken or omitted by, any other Person hereunder. Nothing contained in this Agreement shall be deemed to cause any Secured Party or the Collateral Agent to be considered a partner of or joint venturer with any other Secured Party, the Collateral Agent, the Subsidiary Guarantors or the Company. 21

The above-described indebtedness, liabilities, obligations, covenants, duties and conditions are hereinafter referred to collectively as the "Secured Obligations." The Grantor does also hereby irrevocably assign and convey unto the Noteholder, and hereby grants to the Noteholder a security interest in, all leases now or hereafter existing on any part of the Property and any guaranties thereof and all rents from the Property to secure additionally the Secured Obligations. The Grantor does hereby irrevocably appoint the Noteholder as its attorney-in-fact to do all things which the Grantor might otherwise do with respect to the leasing of the Property, including, without limitation, (i) collecting such rents with or without suit and applying 3

the same, less expenses of collection, to any of the Secured Obligations in such manner as may be determined by the Noteholder, or at the option of the Noteholder, holding the same as security for the payment of all of the Secured Obligations, (ii) leasing, in the name of the Grantor, the whole or any part of the Property which may become vacant, and (iii) employing agents therefor and paying such agents reasonable compensation for their services; provided, however, that until there be an Event of Default (as hereinafter defined), the Grantor may continue to collect and enjoy such rents in the ordinary course of business as the rents become due and payable without accountability to the Noteholder. The curing of such Event of Default, however, shall not entitle the Grantor to do any such things which the Grantor might otherwise do with respect to the Property and the leases thereon or again to collect such rents unless consented to in writing by the Noteholder. The powers and rights granted in this paragraph shall be in addition to the other remedies herein provided for upon the occurrence of an Event of Default and may be exercised independently of or concurrently with any of such remedies. Nothing in the foregoing shall be construed to impose any obligation upon the Noteholder to exercise any power or right granted in this paragraph or to assume any liability under any lease of any part of the Property, and no liability shall attach to the Noteholder for failure or inability to collect any rents under any such lease. The Grantor covenants and warrants that (i) it will comply with all terms and conditions of all leases now existing or that may hereafter come into existence in respect of the Property or of any part thereof; (ii) all leases with respect to the Property now or hereafter in effect are and shall be valid and subsisting leases; (iii) it has not sold, assigned, transferred, mortgaged or pledged, and will not sell, assign, transfer, mortgage or pledge, without the Noteholder's prior written consent, the rents, issues or profits from the Property and leases thereof to any person other than the Noteholder; (iv) no rents, issues or profits derived from the Property and leases, and becoming due subsequent to the date hereof, have been collected or anticipated in advance of their due date by more than thirty (30) days; (v) it will not reduce the rental due under any lease of all or any part of the Property without the Noteholder's prior written consent; and (vi) upon request of the Noteholder, it will serve such written notice or notices as the Noteholder may from time to time require upon the tenant(s) under such leases or occupant(s) of the Property or any part thereof, it will execute and deliver to the Noteholder such other instruments or documents reasonably requested by the Noteholder for the purpose of securing or exercising its rights herein and it will provide to the Noteholder true copies or originals of such leases and all amendments, supplements, renewals or correspondence related thereto. All leases and renewals and extensions of existing leases shall be subject in all respects to the Noteholder's advance written approval. Whenever in this paragraph there is a reference to "leases," such reference shall also apply to subleases and any other forms of agreement for the use of the Property or any part thereof. So long as no Event of Default exists under this Deed of Trust, and except as specifically provided herein to the contrary, the Grantor shall remain in quiet use, possession and management of the Property, and in the enjoyment of the income, revenue and profits therefrom. So long as any part of the Secured Obligations remains outstanding, the Grantor covenants and agrees as follows: 1. TAXES AND ASSESSMENTS. The Grantor will pay, promptly when due, all taxes, assessments and public charges upon the Property, except for those being contested in good faith, by appropriate proceedings, and for which adequate reserves have been established (in accordance with GAAP (as defined in the Credit Agreement)), and immediately thereafter will 4

forward to the Noteholder official receipts evidencing such payments; or in the alternative and at the option of the Noteholder, exercisable at any time upon the occurrence and during the continuance of an Event of Default, will deposit with the Noteholder, at such time or times as the Noteholder directs, such amounts as are necessary, in the sole and absolute discretion of the Noteholder, to enable the Noteholder to make timely payment of such taxes, assessments and charges. Such amounts so deposited shall bear no interest and may be commingled with other funds held by the Noteholder. If, at any time, the Noteholder determines in its sole and absolute discretion that a deficiency exists between the amounts deposited and the actual amount required to be paid with respect to taxes, assessments and charges, then the Grantor shall immediately pay such deficiency upon notification thereof by the Noteholder. The Grantor does hereby grant to the Noteholder a security interest in the funds it receives under this paragraph 1 to secure the payment of the Secured Obligations. 2. INSURANCE; DAMAGE TO PROPERTY. a. The Grantor will continuously insure the Property with a responsible company or companies reasonably satisfactory to the Noteholder against fire (with extended coverage) in the full insurable value of the Property, and against such other casualties and in such amounts as required by the Noteholder pursuant to the Credit Agreement. The insurance policy (or policies) will have attached thereto a standard mortgagee clause, without contribution, in favor of the Noteholder, as its interest may appear, and will otherwise be in form reasonably acceptable to the Noteholder, and the Grantor will cause such policy (or policies) to provide that it (they) may not be canceled without thirty (30) days' prior written notice to the Noteholder. The Grantor will deliver to the Noteholder certificates evidencing that the Noteholder has been named as loss payee and additional insured on all such insurance, and certificates of insurance at least fifteen (15) days prior to the renewal of such insurance policy (or policies). The Noteholder shall have the right, exercisable at any time upon the occurrence and during the continuance of an Event of Default, to require the Grantor to deposit with the Noteholder, at such time or times as the Noteholder directs, such amounts as are necessary, in the sole and absolute discretion of the Noteholder, to enable the Noteholder to make timely payment of the premiums on such policy or policies. Such amounts so deposited shall bear no interest and may be commingled with other funds held by the Noteholder. If, at any time, the Noteholder determines in its sole and absolute discretion that a deficiency exists between the amounts deposited and the actual amount required to be paid with respect to such premiums, then the Grantor shall immediately pay such deficiency upon notification thereof by the Noteholder. The Grantor does hereby grant to the Noteholder for the benefit of the Noteholder a security interest in the funds it receives under this paragraph 2 to secure the payment of the Secured Obligations. As to such insurance, upon the occurrence and during the continuance of an Event of Default, the Noteholder may, after ten (10) days' written notice mailed to the Grantor at its last known address, change any or all of the coverages, terms, amounts or insurers, cause any policy to name the Noteholder as insured as its interest may appear, surrender existing policies for cancellation, obtain any cancellation, obtain any additional insurance it so desires, pay any required premiums and receive premium refunds, and in any such event any premium adjustments shall be charged against or credited to the Secured Obligations. In the event any claim for loss covered by such insurance is not settled within one hundred twenty (120) days after the occurrence of such loss, the Noteholder may negotiate with any insurance companies involved and make a reasonable settlement of such claim, and the Noteholder and such insurance companies, upon such settlement 5

being made, shall not be liable in any manner to the Grantor with respect to such claim and settlement. b. The Grantor shall promptly notify the Noteholder of any damage to or destruction of the Property or any part thereof having an aggregate fair market value in excess of $250,000. In case of any damage to or destruction of the Property or any part thereof, the Grantor, whether or not the insurance proceeds, if any, received on account of such damage or destruction shall be sufficient for the purpose, at the Grantor's expense, will promptly commence and complete the restoration, replacement or rebuilding of the Property as nearly as possible to its value, condition and character immediately prior to such damage or destruction. Insurance proceeds received by the Noteholder in the aggregate amount of less than $1,000,000 in any fiscal year of the Grantor under any policy or policies covering the Property or any part thereof shall be remitted to the Grantor, provided that (i) no Default (as defined in the Credit Agreement) or Event of Default then exists and (ii) the Grantor restores that portion of the Property so damaged or destroyed within 360 days of the occurrence of such damage or destruction. Insurance proceeds received by the Noteholder in the aggregate amount of more than $1,000,000 in any fiscal year of the Grantor under any policy or policies of insurance covering the Property or any part thereof shall first be applied toward the payment of the amount owing on the Secured Obligations in such order of application as the Noteholder may elect whether or not the same may then be due or be otherwise adequately secured; provided, however, that such proceeds shall be made available for the restoration of the portion of the Property damaged or destroyed if written application for such use is made within thirty (30) calendar days of receipt of such proceeds and the following conditions are satisfied: (i) the Grantor has in effect business interruption insurance in the amounts required by the Credit Agreement; (ii) no Default or Event of Default exists (and if an Event of Default shall occur during restoration the Noteholder may, at its election, apply any insurance proceeds then remaining in its hands to the reduction of the Secured Obligations); (iii) the Grantor shall have submitted to the Noteholder plans and specifications for the restoration which shall be reasonably satisfactory to it; (iv) the Grantor shall submit to the Noteholder fixed price contracts with good and responsible contractors and materialmen covering all work and materials necessary to complete restoration and providing for a total completion price not in excess of the amount of insurance proceeds available for restoration, or, if a deficiency shall exist, the Grantor shall have deposited the amount of such deficiency with the Noteholder; and (v) the Grantor shall have provided to the Noteholder a written release from each insurer under such policies of insurance to the effect that all such proceeds are paid without any reservation of rights and that such insurer has no cause of action, right of set-off or other claim against the Grantor or the insured under such policies. Any insurance proceeds to be released pursuant to the foregoing provisions may at the option of the Noteholder be disbursed from time to time as restoration progresses to pay for restoration work completed and in place and such disbursements may at the Noteholder's option be made directly to the Grantor or to or through any contractor or materialman to whom payment is due or to or through a construction escrow to be maintained by a title insurer acceptable to the Noteholder. The Noteholder may impose such further conditions upon the release of insurance proceeds (including the receipt of title insurance) as are customarily imposed by prudent construction lenders to insure the completion of the restoration work free and clear of all liens or claims for liens. All title insurance charges and other costs and expenses paid to or for the account of the Grantor in connection with the release of such insurance proceeds shall constitute so much additional indebtedness hereby secured to be payable upon demand with interest at the rate 6

applicable to Real Estate Term Loans 1, 2, 3 & 4 at the time such costs or expenses are incurred. The Noteholder may deduct any such costs and expenses from insurance proceeds at any time standing in its hands. If the Grantor fails to request that insurance proceeds be applied to the restoration of the Property or if the Grantor makes such a request but fails to complete restoration within twelve (12) months of the occurrence of the damage or destruction of the Property giving rise to payment of such insurance proceeds, the Noteholder shall have the right, but not the duty, to release the proceeds thereof for use in restoring the Property or any part thereof for or on behalf of the Grantor in lieu of applying said proceeds to the Secured Obligations and for such purpose may do all acts necessary to complete such restoration, including advancing additional funds, and any additional funds so advanced shall constitute part of the indebtedness hereby secured and shall be payable on demand with interest at the Default Rate applicable to Real Estate Term Loans 1, 2, 3 & 4. Notwithstanding the foregoing, if, despite the exercise of reasonable diligence, the Grantor is unable to complete the restoration of the Property within twelve (12) months of the occurrence of the damage or destruction of the Property giving rise to the payment of insurance proceeds, the Grantor shall have not more than three (3) additional months (the "Extended Restoration Period") to complete such restoration, provided that (i) no Default or Event of Default shall have occurred and be continuing at the commencement of or at any time during the Extended Restoration Period and (ii) the Noteholder remains satisfied during the Extended Restoration Period that the Grantor is pursuing such completion with reasonable diligence at all times. 3. PRESERVATION AND MAINTENANCE OF PROPERTY. Except as otherwise may be permitted in the Credit Agreement, the Grantor will keep the Property (including any private roads on or over which the Grantor has any easement or right appurtenant to the Property) in good order and repair, including the making of such replacements as may be necessary for that purpose, and the Grantor will promptly restore any part of the Property which may be damaged by fire or other casualty as required by paragraph 2 hereof. 4. WASTE. The Grantor will not permit, suffer or commit any material waste, impairment or deterioration of, nor allow any material nuisance to exist upon, the Property or any part thereof. 5. ASSURANCES OF TITLE. The Grantor will execute, or cause to be executed, such further assurances of title to the Property, and will take, and cause to be taken, such steps, including legal proceedings, as may at any time be reasonably necessary to perfect the title to the Property in the Trustee. 6. CONTRACTS. The Grantor will keep and maintain at its principal place of business copies of all written contracts, leases and other instruments which affect the Property. Such contracts, leases and other instruments shall be subject to examination and inspection by the Noteholder at any reasonable time and from time to time, and, if no Event of Default has occurred, upon reasonable prior notice. 7. LIENS AND ENCUMBRANCES. The Grantor will not, without the prior written consent of the Noteholder, permit or suffer to exist any lien or encumbrance on the Property, or interest therein (legal or equitable), or any part thereof, either inferior or superior in right to the lien of this Deed of Trust, other than Permitted Exceptions. 7

8. WAIVER OF EXEMPTIONS. The Grantor will not set up or claim the benefit of any homestead or other exemption of law, or any other law or rule of law intended for its advantage or protection as an obligor under any note evidencing the Secured Obligations (collectively, the "Notes"), under the ISDA Master Agreement or under this Deed of Trust or providing for its release or discharge from any liability under the Notes, the ISDA Master Agreement or this Deed of Trust on account of any facts or circumstances other than full and complete payment of all amounts due under the Notes, the ISDA Master Agreement and this Deed of Trust, all of such exemptions and benefits being hereby expressly waived. 9. EMINENT DOMAIN. The Grantor covenants and agrees to give prompt written notice to the Noteholder by certified mail, postage prepaid, return receipt requested, of any taking or condemnation, or any threatened or pending proceedings for the taking or condemnation, of any part of the Property under any power of eminent domain; and in the event that title to, or possession of, the Property or any portion thereof, is taken or condemned under any power of eminent domain, then the Grantor will (and hereby does) assign to the Noteholder, and will forthwith upon receipt pay to the Noteholder, the proceeds and consideration resulting from taking or condemnation, not to exceed the unpaid balance of the Secured Obligations, such proceeds so paid to be applied to the Secured Obligations. 10. TRANSFER OF PROPERTY. The Grantor will not, without the prior written consent of the Noteholder, lease, bargain, sell, transfer, assign or convey the Property, or any portion thereof, or any legal or equitable interest therein. NOTICE -- THE DEBT SECURED HEREBY IS SUBJECT TO CALL IN FULL OR THE TERMS THEREOF BEING MODIFIED IN THE EVENT OF SALE OR CONVEYANCE OF THE PROPERTY CONVEYED. 11. USE OF PROPERTY. The Grantor will not, without the prior written consent of the Noteholder, (a) change, or permit any material changes in, the general use for which all or any part of the Property was intended at the time of the execution of this Deed of Trust, or (b) initiate or acquiesce in a change in the zoning classification of the Property. 12. ENTRY; PROTECTION OF THE NOTEHOLDER'S SECURITY. The Grantor does hereby grant to the Noteholder, the Trustee and their designees the right to enter, examine and inspect the Property, and to do such other things as are permitted under this Deed of Trust, at any reasonable time and from time to time, and if no Event of Default has occurred, upon reasonable prior notice. In the event (a) the Grantor fails to perform any of its covenants or agreements herein contained, or (b) any action or proceeding is commenced or threatened which affects the Property or title thereto or the interest of the Trustee or the Noteholder therein, including, without limitation, eminent domain, insolvency, arrangements or proceedings involving a bankrupt or decedent, then, in any of such events, the Noteholder may, at its option, make such appearances, disburse such amount and take such action as the Noteholder deems necessary, in its reasonable discretion, to protect its interest, including, without limitation, (i) the employment of attorneys and disbursement of attorneys' fees, (ii) the entry upon the Property to make repairs, (iii) the procurement of insurance as provided in paragraph 2 hereof, and (iv) if the Property is subject to another deed of trust or lien, whether inferior or superior hereto, the curing of any default in the performance of any of the terms and provisions thereof, or if the indebtedness thereby secured is 8

accelerated, the purchase or payment in full of such indebtedness, all on such terms as the Noteholder shall, in its sole and absolute discretion, deem necessary or advisable. Any amounts disbursed by the Noteholder pursuant to the provisions of this paragraph 12 shall be added to, and deemed a part of, the Secured Obligations, shall be secured in the same manner as the Notes and the other Real Estate Term Loan Obligations are secured, shall bear interest from the date of the disbursement thereof at a fluctuating rate of interest equal to the Default Rate (as defined in the Credit Agreement) applicable to Real Estate Term Loans 1, 2, 3 & 4, and shall, together with the interest thereon, be repayable by the Grantor on demand. 13. ESTOPPEL CERTIFICATE. The Grantor will, within ten (10) days of being requested in writing by the Noteholder so to do, furnish a written statement to the Noteholder, duly acknowledged, setting forth in detail the Secured Obligations and any right of setoff, counterclaim or other defense which exists against the payment or performance thereof. 14. ENVIRONMENTAL PROTECTION. The Grantor covenants and agrees as follows: a. The Grantor warrants and represents that it has investigated or caused to be investigated the previous ownership and uses of the Property, in a manner consistent with good commercial practices, to determine whether activities have been conducted which might involve the use, manufacturing, storage or disposal of Hazardous Substances (as defined in the Credit Agreement), and this investigation has revealed no fact which would indicate that the Property has been involved in the use, manufacturing, storage or disposal of Hazardous Substances other than in accordance with all applicable Environmental Laws (as defined in the Credit Agreement). This investigation has taken into account, among other factors, (i) the relationship of the purchase price to the value of the Property if uncontaminated when originally purchased by the Grantor, (ii) commonly known or reasonably ascertainable information about the Property, and (iii) the obviousness of the presence or likely presence of contamination at the Property. b. The Grantor warrants and represents to the best of its knowledge after due investigation that it has disclosed to the Noteholder all pending or threatened litigation and all orders, rulings, notices, permits or investigations regarding Hazardous Substances on the Property. c. The Grantor and any other parties, including, but not limited to, tenants, licensees and occupants, will not be involved in any activity at or near the Property, which activity is likely to involve or lead to (i) the use, manufacture, storage or disposal of Hazardous Substances except in accordance with all applicable Environmental Laws and all other laws, ordinances and regulations, or (ii) the imposition of liability on the Grantor or any other subsequent or former owner of the Property or the creation of a lien on the Property under any Environmental Laws. d. The Grantor will comply in all material respects with the requirements of all Environmental Laws and shall promptly notify the Noteholder in the event of the discovery of Hazardous Substances at the Property which are not in compliance with applicable Environmental Laws. Further, the Grantor will promptly forward to the Noteholder copies of all orders, notices, permits, applications and other communications and reports in connection with any discharge, spillage, use or discovery of Hazardous Substances on the Property which constitutes or is alleged to constitute a violation of any Environmental Law. Grantor will not permit any other party, 9

including, but not limited to, tenants, licensees and occupants to conduct any such discharge, spillage or use of any Hazardous Substances except in compliance with all applicable Environmental Laws and shall take immediate action to stop any such activity and to correct any violations resulting therefrom. e. The Grantor agrees that if at any time the Noteholder has reasonable cause to believe there are Hazardous Substances upon the Property that are being used, stored, manufactured or disposed of other than in accordance with all applicable Environmental Laws, the Noteholder may with prior notice to Grantor obtain, at Grantor's cost, an environmental site assessment or environmental audit report of reasonable scope under the circumstances from a firm acceptable to the Noteholder, to assess with a reasonable degree of certainty (i) the presence of any such Hazardous Substances and (ii) the cost in connection with the abatement, cleanup or removal of such. f. The Grantor agrees that in the event of the presence of any Hazardous Substances upon the Property which is not in compliance with all applicable Environmental Laws, whether or not the same originates or emanates from the Property, or if Grantor shall fail to comply with all requirements of all applicable Environmental Laws, the Noteholder may at its election, but without the obligation to do so, (i) give such notices as are required by applicable Environmental Laws, (ii) cause such work to be performed at the Property or (iii) take any and all other actions as the Noteholder shall deem necessary or advisable in order to abate, remove and clean up the Hazardous Substances or otherwise cure the Grantor's noncompliance. g. The Grantor shall be liable for all reasonable costs and expenses incurred by or asserted against the Noteholder arising under this paragraph even if said costs and expenses exceed the amount of the loans secured by this Deed of Trust. h. Any amounts disbursed by the Noteholder pursuant to the provisions of this paragraph 14 shall be added to, and deemed a part of, the Secured Obligations, shall be secured in the same manner as the Notes and the other Real Estate Term Loan Obligations are secured, shall bear interest from the date of the disbursement thereof at a fluctuating rate of interest equal to the Default Rate (as defined in the Credit Agreement) applicable to Real Estate Term Loans 1, 2, 3 & 4, and shall, together with the interest thereon, be repayable by the Grantor on demand. 15. COMPLIANCE WITH LAWS. Except as otherwise may be permitted in the Credit Agreement, the Grantor shall comply with all applicable laws, ordinances, rules, regulations and judicial or administrative orders (collectively, "Laws") now in force or hereafter enacted or promulgated relating to the construction, maintenance, operation and use of the Property, or any part thereof, including, but not limited to, Environmental Laws. Without limiting the generality of the foregoing, the Grantor shall apply for, obtain, keep in force and comply with all governmental permits, licenses and approvals (collectively, "Permits") now or hereafter at any time required in connection with the construction, maintenance, operation and use of the Property, or any part thereof, except where the failure to apply for, obtain, keep in force and comply with all Permits could not reasonably be expected to have a Material Adverse Effect (as defined in the Credit Agreement). The Grantor represents and warrants that, as of the date hereof, its activities and the Property are in compliance with all Laws in all material respects and that all Permits are in full force and effect in all material respects. To the extent required under the Credit Agreement, the Grantor 10

covenants and agrees to give prompt written notice to the Noteholder by certified mail, postage prepaid, return receipt requested, of any present or future pending or threatened litigation and any orders, rulings, notices, permits or investigations with respect to Laws and/or Permits if such litigation, orders, rulings, notices, permits or investigations with respect to the Property. 16. EVENTS OF DEFAULT AND FORECLOSURE. If any one or more of the following events (herein sometimes referred to as "Events of Default") shall occur: a. An Event of Default as defined in the Credit Agreement or any renewal, extension or modification thereof or any substitution or replacement therefor; or b. Default under any other lien or encumbrance placed on the Property, or any interest therein (legal or equitable), or any part thereof, either inferior or superior in right to the lien of this Deed of Trust, and such default shall continue beyond any applicable grace period; or c. The termination of, or occurrence of any event affecting, the validity of this Deed of Trust or the priority of this Deed of Trust as to all outstanding or future advances intended to be secured hereby; or d. The passage after the date of this Deed of Trust of any law of the Commonwealth of Virginia deducting from the value of the land, for the purposes of taxation, any lien thereon, or providing for, or changing in any way the laws relating to, the taxation of deeds of trust or the notes or debts secured by deeds of trust for state or local purposes, or the manner of the collection of any such taxes, so as to impair the lien of this Deed of Trust or the security afforded hereunder, unless the Grantor is permitted by law to pay the whole of such tax imposed upon this Deed of Trust and/or the Secured Obligations (in addition to all other payments required hereunder) and the Grantor pays such tax and agrees to pay and thereafter pay such tax whenever levied; or e. The passage of any law or the decision of any court rendering or declaring any material covenant or agreement set out in any Note, the ISDA Master Agreement, any agreement evidencing or securing any of the other Real Estate Term Loan Obligations, or in this Deed of Trust to be legally unenforceable, inoperative, void or voidable; then, in any of such events, the Trustee and the Noteholder shall, in addition to any other rights and remedies provided in the Credit Agreement, or by law or in equity, have the following rights and remedies, any one or more of which shall be exercisable from time to time at the Noteholder's option and without notice to the Grantor: (i) The Noteholder may declare the Notes, or any of them, and all of the other Secured Obligations immediately due and payable, without demand; (ii) The Noteholder may dispossess the Grantor of the Property and exercise any right or remedy provided in this Deed of Trust with respect to taking possession of the Property and collecting the rents relating thereto; (iii) The Noteholder may apply for and obtain the appointment of a receiver for the Property, with the power to collect the rents, issues and profits therefrom, without regard to the value of the Property or of the solvency of any person or persons liable 11

for the payment of the Secured Obligations, and the Grantor does hereby waive any and all defenses to the application for appointment of such receiver and consent to the appointment of such receiver without notice, but reserves the right to apply for vacation of any order of appointment of such receiver, or for any other appropriate relief, upon showing that none of the foregoing events of default occurred prior to application for the appointment of such receiver or during the pendency of such application in court; and (iv) The Trustee may foreclose by a sale of the Property as follows: (A) The Trustee may take possession of the Property and proceed to sell the same at auction at the premises or at such other place in the city or county in which the Property or the greater part thereof lies, or in the corporate limits of any city surrounded by or contiguous to such county, or in the case of annexed land, in the county of which the land was formerly a part, as the Trustee may select upon such terms and conditions as the Trustee may deem best, after first advertising the time, place and terms of sale in at least three (3) consecutive issues (which may be on consecutive days), in advance of the date of such sale, of a newspaper published or having general circulation in the county or city in which the Property or some portion thereof is located. (B) The power of sale above granted may be exercised at different times as to different portions of the Property, and if for any reason any executory contract of sale shall not be performed, then new contracts may be made with respect to the same portion of the Property (with or without other portions). If the Trustee deems it best for any reason to postpone or continue the sale at any time or from time to time, they may do so. (C) Full power and authority is hereby expressly granted and conferred upon the Trustee to make, execute, and deliver all necessary deeds of conveyance for the purpose of vesting in the purchaser or purchasers complete and entire legal and equitable title to the Property, or the portion thereof so sold, and the recitals therein shall be received in all courts of law and equity as prima facie evidence of the matters therein stated; and at such sale the Noteholder may become a purchaser, and no purchaser shall be required to see to the proper application of the purchase money. (D) The proceeds of such sale shall be applied, first, to discharge the expenses of executing their Deed of Trust, including a commission to the Trustee of three percent (3%) of the gross proceeds of sale; next, to discharge all taxes, levies, and assessments on the Property, with costs and interest, including a proper proration thereof for the current year; next, to reimburse the Trustee and the Noteholder for all amounts expended by them or any of them pursuant to the provisions of this Deed of Trust, with interest thereon; next, to pay the accrued interest on the unpaid principal balance due under the Notes and under the other Secured Obligations; next, to pay such unpaid principal balance of the Notes and the other Secured Obligations; next to pay any remaining Secured Obligations; next, to pay any indebtedness secured by any lien of record inferior to the lien of this Deed 12

of Trust; and any residue of such proceeds shall be paid to the Grantor provided, however, that the Trustee as to such residue shall not be bound by any inheritance, devise, conveyance, assignment or lien of or upon the Grantor's equity, without actual notice thereof prior to distribution. 17. [Reserved.] 18. NONWAIVER. No delay, act or failure to act, by the Trustee and the Noteholder, or any of them, however long continued, shall be construed as a waiver of any of their rights hereunder or of any default by the Grantor. 19. NO LIABILITY OR OBLIGATION ON THE TRUSTEE OR THE NOTEHOLDER. Nothing in this Deed of Trust shall be construed to impose any obligation upon the Noteholder or the Trustee to expend any money or to take any other discretionary act herein permitted, and neither the Noteholder nor the Trustee shall have any liability or obligation for any delay or failure to take any discretionary act. The Trustee shall not be required to see that this Deed of Trust is recorded and shall not be liable for the default or misconduct of the Noteholder or any agent or attorney appointed by them in pursuance hereof, or for anything whatever in connection with this Deed of Trust, except willful misconduct or gross negligence. The Trustee may act upon any instrument or paper believed by it in good faith to be genuine and to be signed by the proper party or parties, and shall be fully protected for any action taken or suffered by them in reliance thereon. 20. RELEASE UPON FULL PAYMENT. Upon full payment of all sums due under the Notes, the ISDA Master Agreement, this Deed of Trust and the other Secured Obligations, the Trustee shall, upon the request of, and at the cost of, the Grantor, execute a proper release of this Deed of Trust. 21. SUBSTITUTION OF THE TRUSTEE. Notwithstanding anything herein contained to the contrary, if the Trustee fails, refuses, or becomes unable to act, or if for any reason the Noteholder, in its sole and absolute discretion, deems it advisable, the Noteholder is hereby authorized and empowered to appoint, by an instrument recorded wherever this Deed of Trust is recorded, one or more other Trustees, in the place and stead of the Trustee named herein, which substitute Trustee or Trustees shall have all rights, powers, and authority and be charged with all the duties that are conferred or charged upon the Trustee named herein; and if more than one Trustee is so named, any one or more of such Trustees may act hereunder without the joinder of any other Trustee or Trustees and any act taken hereunder by any one or more Trustees shall be as effective as if taken by all Trustees. 22. ADVANCES AND FUTURE ADVANCES. It is understood and agreed that the Noteholder reserves the right, but shall have no obligation, to make additional advances of proceeds in connection with the Real Estate Term Loan Obligations from time to time, including the advance of the proceeds of Real Estate Term Loan 4 (as defined in the Credit Agreement) and the readvance of any sums previously repaid on the Notes. 23. INDEMNIFICATION BY THE GRANTOR. The Grantor shall protect and indemnify the Trustee and the Noteholder from and against all liabilities, obligations, claims, 13

damages, penalties, causes of action, costs and expenses (including, without limitation, reasonable attorneys' fees and disbursements), imposed upon or incurred by or asserted against the Trustee, the Noteholder or the directors, officers or employees of the Noteholder by reason of (a) ownership of the Property or any interest therein, or receipt of any rent or other sum therefrom, (b) any accident to, injury to or death of persons or loss of or damage to property occurring on or about the Property or the adjoining sidewalks, curbs, vaults or vault space, if any, streets or ways, (c) any use, nonuse or condition of the Property or the adjoining sidewalks, curbs, vaults or vault space, if any, streets or ways, (d) any failure on the part of the Grantor to perform or comply with any of the terms, covenants, conditions and agreements set forth in this Deed of Trust, any of the Notes, the ISDA Master Agreement, or any other agreements executed by the Grantor or any other persons liable for the payment of the Secured Obligations, (e) performance of any labor or services or the furnishing of any materials or other property in respect of the Property or any part thereof for construction or maintenance or otherwise, (f) any action brought against the Trustee or the Noteholder, or any of them, attacking the validity, priority or enforceability of this Deed of Trust, any Note, the ISDA Master Agreement, or any other agreements executed by the Grantor or any other persons liable for the payment of the Secured Obligations, and/or (g) the presence of Hazardous Substances on the Property; provided, however, that the Grantor shall not be obligated to indemnify the Trustee or the Noteholder from any loss, damage, cost or expense directly attributable to their or any of their gross negligence or willful misconduct. Any amounts payable to the Trustee or the Noteholder under this paragraph 23 which are not paid within ten (10) days after written demand therefor by the Trustee or the Noteholder shall be added to, and deemed a part of, the Secured Obligations, shall be secured in the same manner as the Notes and the other Real Estate Term Loan Obligations are secured, shall bear interest from the date of the disbursement thereof at a fluctuating rate of interest equal to the Default Rate (as defined in the Credit Agreement) applicable to Real Estate Term Loans 1, 2, 3 & 4, and shall, together with the interest thereon, be repayable by the Grantor on demand.

Exhibit 99 Wednesday June 19, 5:20 pm Eastern Time Press Release SOURCE: Trex Company, Inc. Trex Company Completes Debt Refinancing WINCHESTER, Va.--(BUSINESS WIRE)--June 19, 2002--Trex Company, Inc. (NYSE: TWP - News), manufacturer of Trex(R) Easy Care Decking(R), today completed a refinancing of total indebtedness of $47.6 million outstanding under its existing senior credit facility and various real estate loans. The Company refinanced this indebtedness from the proceeds of its sale of $40 million principal amount of senior secured notes due 2009 and borrowings under new real estate loans having a total principal amount of $12.6 million. In connection with the refinancing, the Company replaced its existing $17 million revolving credit facility with a $20 million revolving credit facility with a new lender. The senior secured notes, which were privately placed with institutional investors, will accrue interest at an annual rate of 8.32%. Five principal payments of $8 million annually to retire the notes will be payable beginning on the third anniversary of the closing date. The new revolving credit facility and real estate loans will accrue interest at annual rates equal to LIBOR plus specified margins and will mature on the third anniversary of the closing date. Branch Banking and Trust Company of Virginia is the lender under the credit facility and real estate loans. "This financing provides us with a stable capital structure for the long term, at attractive terms," said Trex Company President Robert Matheny. "In addition, by refinancing this debt we have eliminated the former lender's conditional right under an existing warrant to purchase 353,778 shares of common stock at $14.89 per share." Early retirement of the outstanding indebtedness will result in a one-time non-cash charge to interest expense of $2.4 million in the second quarter of 2002 as a result of accelerated amortization of the remaining debt discount balance. This debt discount was previously scheduled to be amortized through January 31, 2003.

"We are pleased that this refinancing has been successfully executed," concluded Matheny. "Having this financial foundation is another important step in the continuing development of the Trex Company."
