CHANGE IN CIRCUMSTANCES SECTION 9.01 Basis for Determining Interest Rate Inadequate or Unfair. If on or prior to the first day of any LIBOR Rate Loan: (a) the Lender determines that deposits in Dollars (in the applicable amounts) are not being offered in the relevant market, or (b) the London Interbank Offered Rate as determined by the Lender will not adequately and fairly reflect the cost to the Lender of funding LIBOR Rate Loans, the Lender shall forthwith give notice thereof to the Borrower, whereupon until the Lender notifies the Borrower that the circumstances giving rise to such suspension no longer exist, the obligation of the Lender to make LIBOR Rate Loans specified in such notice, or to permit continuations or conversions into LIBOR Rate Loans, shall be suspended. Unless the Borrower notifies the Lender at least 2 Business Days before the date of any Borrowing of LIBOR Rate Loans for which a Notice of Borrowing has previously been given, or continuation or conversion into such LIBOR Rate Loans for which a Notice of Continuation or Conversion has previously been given, that it elects not to borrow or so continue or convert on such date, such Borrowing shall instead be made as a Base Rate Borrowing, or such LIBOR Rate Loan shall be converted to a Base Rate Loan. SECTION 9.02 Illegality. If, after the date hereof, the adoption of any applicable law, rule or regulation, or any change therein or any existing or future law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof (any such agency being referred to as an "Governing Authority" and any such event being referred to as a "Change of Law"), or compliance by the Lender (or its Lending Office) with any request or 44 directive (whether or not having the force of law) of any Governing Authority shall make it unlawful or impossible for the Lender (or its Lending Office) to make, maintain or fund its LIBOR Rate Loans, the Lender shall forthwith give notice thereof to the Borrower, whereupon until the Lender notifies the Borrower that the circumstances giving rise to such suspension no longer exist, the obligation of the Lender to make or permit continuations or conversions of LIBOR Rate Loans shall be suspended. Before giving any notice to the Borrower pursuant to this Section, the Lender shall designate a different Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of the Lender, be otherwise disadvantageous to the Lender. If the Lender shall determine that it may not lawfully continue to maintain and fund any of its outstanding LIBOR Rate Loans to maturity, and shall so specify in such notice, the Borrower shall immediately prepay in full the then outstanding principal amount of each LIBOR Rate Loan of the Lender, together with accrued interest thereon. SECTION 9.03 Increased Cost and Reduced Return. (a) If after the date hereof, a Change of Law or compliance by the Lender (or its Lending Office) with any request or directive (whether or not having the force of law) of any Governing Authority: (i) shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding with respect to any LIBOR Rate Loan any such requirement included in an applicable LIBOR Rate Reserve Percentage) against assets of, deposits with or for the account of, or credit extended by, the Lender (or its Lending Office); or (ii) shall impose on the Lender (or its Lending Office) or on the London interbank market any other condition affecting its LIBOR Rate Loans, its Note or its obligation to make LIBOR Rate Loans; and the result of any of the foregoing is to increase the cost to the Lender (or its Lending Office) of making or maintaining the Loan, or to reduce the amount of any sum received or receivable by the Lender (or its Lending Office) under this Agreement or under its Note with respect thereto, by an amount deemed by the Lender to be material, then the Lender shall give notice thereof to the Borrower within 90 days after the Lender becomes aware of such matters and, within 15 days after demand by the Lender, the Borrower shall pay to the Lender such additional amount or amounts as will compensate the Lender for such increased cost or reduction. (b) If the Lender shall have determined that after the date hereof the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof, or compliance by the Lender (or its Lending Office or the bank holding company of which the Lender is a subsidiary) with any request or directive regarding capital adequacy (whether or not having the force of law) of any Governing Authority, has or would have the effect of reducing the rate of return on the Lender's (or such bank holding company's) capital as a consequence of its obligations hereunder to a level below that which the Lender (or such bank holding company) could have achieved but for such adoption, change or compliance (taking into consideration the Lender's (or such bank holding 45 company's) policies with respect to capital adequacy) by an amount deemed by the Lender to be material, then from time to time the Lender shall give notice thereof to the Borrower within 90 days after the Lender becomes aware of such matters and, within 15 days after demand by the Lender, the Borrower shall pay to the Lender such additional amount or amounts as will compensate the Lender (or such bank holding company) for such reduction. (c) The Lender will promptly notify the Borrower of any event of which it has knowledge, occurring after the date hereof, which will entitle the Lender to compensation pursuant to this Section and will designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of the Lender, be otherwise disadvantageous to the Lender. A certificate of the Lender claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, the Lender may use any reasonable averaging and attribution methods. (d) The provisions of this Section 9.03 shall be applicable with respect to any Participant, Assignee or other Transferee, and any calculations required by such provisions shall be made based upon the circumstances of such Participant, Assignee or other Transferee. The Lender agrees that it will not seek compensation or reimbursement provided for in this Section 9.03 unless the Lender as a matter of policy intends generally to seek comparable compensation or reimbursement from other borrowers similarly situated and with similarly documented financial accommodations. SECTION 9.04 Base Rate Loans Substituted for LIBOR Rate Loans. If (i) the obligation of the Lender to make or maintain LIBOR Rate Loans has been suspended pursuant to Section 9.02 or (ii) the Lender has demanded compensation under Section 9.03, and the Borrower shall, by at least 5 Business Days' prior notice to the Lender, have elected that the provisions of this Section shall apply, then, unless and until the Lender notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer apply: (a) all Loans which would otherwise be made by the Lender as, or permitted to be continued as or converted into LIBOR Rate Loans shall instead be made as or converted into Base Rate Loans, and (b) after each of its LIBOR Rate Loans has been repaid, all payments of principal which would otherwise be applied to repay such LIBOR Rate Loans shall be applied to repay its Base Rate Loans instead.

The Borrower shall indemnify the Lender and each Affiliate thereof and its respective directors, officers and employees from, and hold each of them harmless against, any and all losses, liabilities, claims or damages to which any of them may become subject, insofar as such losses, liabilities, claims or damages arise out of or result from any transaction contemplated by this Agreement or any other Loan Document or any actual or proposed use by the Borrower of the proceeds of any extension of credit by the Lender 48 hereunder or breach by the Borrower of this Agreement or any other Loan Document or from any investigation, litigation (including, without limitation, any actions taken by the Lender or to enforce this Agreement or any of the other Loan Documents) or other proceeding (including, without limitation, any threatened investigation or proceeding) relating to the foregoing, and the Borrower shall reimburse the Lender, and each Affiliate thereof and its respective directors, officers, and employees, upon demand for any expenses (including, without limitation, legal fees) incurred in connection with any such investigation or proceeding; but excluding any such losses, liabilities, claims, damages or expenses which are determined by a final, non-appealable judgment of a court to have been incurred by reason of the gross negligence or willful misconduct of the Person to be indemnified. In the case of any investigation, litigation or other proceeding to which the indemnity in this Section applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by the Borrower or any Subsidiary or Affiliate thereof, or any of their respective directors, shareholders, or creditors or an Indemnified Party, or any other Person or any Indemnified Party is otherwise a party thereto and whether or not any transaction contemplated by this Agreement or any other Loan Document is consummated. SECTION 11.05 Setoff; Sharing of Setoffs. (a) The Borrower hereby grants to the Lender a lien for all indebtedness and obligations owing to them from the Borrower upon all deposits or deposit accounts, of any kind, or any interest in any deposits or deposit accounts thereof, now or hereafter pledged, mortgaged, transferred or assigned to the Lender or otherwise in the possession or control of the Lender for any purpose for the account or benefit of the Borrower and including any balance of any deposit account or of any credit of the Borrower with the Lender, whether now existing or hereafter established, hereby authorizing the Lender at any time or times with or without prior notice to apply such balances or any part thereof to such of the indebtedness and obligations owing by the Borrower to the Lender then past due and in such amounts as they may elect, and whether or not the Collateral, if any, or the responsibility of other Persons primarily, secondarily or otherwise liable may be deemed adequate. For the purposes of this paragraph, all remittances and property shall be deemed to be in the possession of the Lender as soon as the same may be put in transit to it by mail or carrier or by other bailee. (b) The Borrower agrees, to the fullest extent it may effectively do so under applicable law, that any holder of a participation in the Note, whether or not acquired pursuant to the foregoing arrangements, may exercise rights of setoff or counterclaim and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of the Borrower in the amount of such participation. SECTION 11.06 Amendments and Waivers. Any provision of this Agreement, the Note or any other Loan Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Lender. SECTION 11.07 Independence of Covenants. All covenants under this Agreement and the other Loan Documents shall be given independent effect so that if a particular action or condition is not permitted by any such covenant, the fact that it would be permitted by an 49 exception to, or would be otherwise allowed by, another covenant shall not avoid the occurrence of a Default if such action is taken or such condition exists. SECTION 11.08 Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns; provided that the Borrower may not assign or otherwise transfer any of its rights or obligations under this Agreement. (b) The Lender may at any time sell to one or more financial institutions (each a "Participant") participating interests in any Loan owing to the Lender, the Note held by the Lender, the Commitment hereunder or any other interest of the Lender hereunder. In the event of any such sale by the Lender of a participating interest to a Participant, the Lender's obligations under this Agreement shall remain unchanged, the Lender shall remain solely responsible for the performance thereof, the Lender shall remain the holder of the Note for all purposes under this Agreement, and the Borrower shall continue to deal solely and directly with the Lender in connection with the Lender's rights and obligations under this Agreement. The Lender selling a participating interest to any Participant other than an Affiliate or Related Fund of the Lender in any Loan, the Note, the Commitment or other interest under this Agreement shall, within 10 Domestic Business Days of such sale, provide the Borrower with written notification stating that such sale has occurred and identifying the Participant and the interest purchased by such Participant. (c) The Lender may at any time assign to one or more commercial banks, finance companies, insurance companies or other financial institution or fund which, in each case, in the ordinary course of business extends credit of the type contemplated herein and whose becoming an assignee would not constitute a prohibited transaction under Section 4975 of ERISA (each an "Assignee") all or a proportionate part of its rights and obligations under this Agreement, the Note and the other Loan Documents, and such Assignee shall assume all such rights and obligations, pursuant to an Assignment and Acceptance, executed by such Assignee, the Lender, subject to clause (iii) below, by the Borrower); provided that (i) no interest may be sold by the Lender pursuant to this paragraph (c) unless the Assignee shall agree to assume ratably equivalent portions of the Commitment, (ii) if the Lender is assigning only a portion of the Commitment, then, the amount of the Commitment being assigned (determined as of the effective date of the assignment) shall be in an amount not less than $2,000,000 (except that there shall be no such minimum if the assignment is to any Affiliate or Related Fund of the Lender), and (iii) no interest may be sold by the Lender pursuant to this paragraph (c) to any Assignee that is not an Affiliate or Related Fund of the Lender without the consent of (unless a Default has occurred and is continuing) the Borrower, which consent shall not be unreasonably withheld. Upon (A) execution of the Assignment and Acceptance by the Lender, such Assignee, and (if applicable) the Borrower, (B) delivery of an executed copy of the Assignment to the Borrower, and (C) payment by such Assignee to the Lender of an amount equal to the purchase price agreed between the Lender and such Assignee, such Assignee shall for all purposes be a Lender party to this Agreement and shall have all the rights and obligations of the Lender under this Agreement to the same extent as if it were an original party hereto with a Commitment as set forth in such instrument of assumption, and the Lender shall be released from its obligations 50 hereunder to a corresponding extent, and no further consent or action by the Borrower or the Lender shall be required. Upon the consummation of any transfer to an Assignee pursuant to this Section 11.08(c), the Lender and the Borrower shall make appropriate arrangements so that, if required, a new Note is issued to such Assignee. (d) Subject to the provisions of this Section 11.08, the Borrower authorizes the Lender to disclose to any Participant, Assignee or other transferee (each a "Transferee") and any prospective Transferee which has executed a confidentiality agreement any and all financial information in the Lender's possession concerning the Borrower which has been delivered to the Lender by the Borrower pursuant to this Agreement or which has been delivered to the Lender by the Borrower in connection with the Lender's credit evaluation prior to entering into this Agreement. (e) No Transferee shall be entitled to receive any greater payment under Section 8.03 than the transferor Lender would have been entitled to receive with respect to the rights transferred, unless such transfer is made with the Borrower's prior written consent or by reason of the provisions of Section 9.02 or 9.03 requiring the Lender to designate a different Lending Office under certain circumstances or at a time when the circumstances giving rise to such greater payment did not exist. (f) Anything in this Section 11.08 to the contrary notwithstanding, the Lender may assign and pledge all or any portion of the Loans and/or obligations owing to it to any Federal Reserve Bank or the United States Treasury as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank, provided that any payment in respect of such assigned Loans and/or obligations made by the Borrower to the assigning and/or pledging Lender in accordance with the terms of this Agreement shall satisfy the Borrower's obligations hereunder in respect of such assigned Loans and/or obligations to the extent of such payment. No such assignment shall release the assigning and/or pledging Lender from its obligations hereunder. SECTION 11.09 Confidentiality. The Lender agrees to exercise the same standard of care that it exercises in the handling of its own confidential information to keep any information delivered or made available by the Loan Parties to it which is clearly indicated to be confidential information, confidential from anyone other than persons employed or retained by the Lender who are or are expected to become engaged in evaluating, approving, structuring or administering the Loans; provided that nothing herein shall prevent the Lender from disclosing such information (i) to an Affiliate of the Lender, but subject to the same confidentiality obligations, (ii) upon the order of any court or administrative agency, (iii) upon the request or demand of any regulatory agency or authority having jurisdiction over the Lender, (iv) which has been publicly disclosed, (v) to the extent reasonably required in connection with the exercise of any remedy hereunder, (vi) to the Lender's legal counsel and independent auditors, and (vii) to any actual or proposed Participant, Assignee or other Transferee of all or part of its rights hereunder; provided that should disclosure of any such confidential information be required by virtue of clause (ii) of the immediately preceding sentence, to the extent permitted by law, the Lender shall promptly notify the Borrower of same so as to allow the Borrower to seek a protective order or to take any other appropriate action; provided, further, that, the Lender shall 51 not be required to delay compliance with any directive to disclose any such information so as to allow the Borrower to effect any such action. SECTION 11.10 Representation by Lender. The Lender hereby represents that it is a commercial lender or financial institution which makes loans in the ordinary course of its business and that it will make its Loans hereunder for its own account in the ordinary course of such business; provided that, subject to Section 11.08, the disposition of the Note held by the Lender shall at all times be within its exclusive control. SECTION 11.11 Virginia Law. This Agreement, the Note and all of the other Loan Documents shall be construed in accordance with and governed by the law of the Commonwealth of Virginia. SECTION 11.12 Severability. In case any one or more of the provisions contained in this Agreement, the Note or any of the other Loan Documents should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby and shall be enforced to the greatest extent permitted by law. SECTION 11.13 Interest. In no event shall the amount of interest, and all charges, amounts or fees contracted for, charged or collected pursuant to this Agreement, the Note or the other Loan Documents and deemed to be interest under applicable law (collectively, "Interest") exceed the highest rate of interest allowed by applicable law (the "Maximum Rate"), and in the event any such payment is inadvertently received by the Lender, then the excess sum (the "Excess") shall be credited as a payment of principal, unless the Borrower shall notify the Lender in writing that it elects to have the Excess returned forthwith. It is the express intent hereof that the Borrower not pay and the Lender not receive, directly or indirectly in any manner whatsoever, interest in excess of that which may legally be paid by the Borrower under applicable law. The right to accelerate maturity of any of the Loans does not include the right to accelerate any interest that has not otherwise accrued on the date of such acceleration, and the Lender does not intend to collect any unearned interest in the event of any such acceleration. All monies paid to the Lender hereunder or under any of the Note or the other Loan Documents, whether at maturity or by prepayment, shall be subject to rebate of unearned interest as and to the extent required by applicable law. By the execution of this Agreement, the Borrower covenants, to the fullest extent permitted by law, that (i) the credit or return of any Excess shall constitute the acceptance by the Borrower of such Excess, and (ii) the Borrower shall not seek or pursue any other remedy, legal or equitable, against the Lender, based in whole or in part upon contracting for charging or receiving any Interest in excess of the Maximum Rate. For the purpose of determining whether or not any Excess has been contracted for, charged or received by the Lender, all interest at any time contracted for, charged or received from the Borrower in connection with this Agreement, the Note or any of the other Loan Documents shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread in equal parts throughout the full term of the Commitment. The Borrower and the Lender shall, to the maximum extent permitted under applicable law, (i) characterize any non-principal payment as an expense, fee or premium rather than as Interest and (ii) exclude voluntary prepayments and the effects thereof. The provisions of this Section shall be deemed to be incorporated into the Note and each of the other Loan Documents (whether or not any provision of this Section is 52 referred to therein). All such Loan Documents and communications relating to any Interest owed by the Borrower and all figures set forth therein shall, for the sole purpose of computing the extent of obligations hereunder and under the Note and the other Loan Documents be automatically recomputed by the Borrower, and by any court considering the same, to give effect to the adjustments or credits required by this Section. SECTION 11.14 Interpretation. No provision of this Agreement or any of the other Loan Documents shall be construed against or interpreted to the disadvantage of any party hereto by any court or other governmental or judicial authority by reason of such party having or being deemed to have structured or dictated such provision. SECTION 11.15 Waiver of Jury Trial; Consent to Jurisdiction. The Loan Parties (a) and the Lender irrevocably waive, to the fullest extent permitted by law, any and all right to trial by jury in any legal proceeding arising out of this Agreement, any of the other Loan Documents, or any of the transactions contemplated hereby or thereby, (b) submit to the nonexclusive personal jurisdiction in the Commonwealth of Virginia, the courts thereof and the United States District Courts sitting therein, for the enforcement of this Agreement, the Note and the other Loan Documents, (c) waive any and all personal rights under the law of any jurisdiction to object on any basis (including, without limitation, inconvenience of forum) to jurisdiction or venue within the Commonwealth of Virginia for the purpose of litigation to enforce this Agreement, the Note or the other Loan Documents, and (d) agree that service of process may be made upon it at the address set forth in Section 11.01 for the giving of notice to the Borrower. Nothing herein contained, however, shall prevent the Lender from bringing any action or exercising any rights against any security and against the Borrower personally, and against any assets of the Borrower, within any other state or jurisdiction. SECTION 11.16 Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. SECTION 11.17 Source of Funds -- ERISA. The Lender hereby represents to the Borrower that no part of the funds to be used by the Lender to fund the Loans hereunder from time to time constitutes (i) assets allocated to any separate account maintained by the Lender in which any employee benefit plan (or its related trust) has any interest nor (ii) any other assets of any employee benefit plan. As used in this Section, the terms "employee benefit plan" and "separate account" shall have the respective meanings assigned to such terms in Section 3 of ERISA.
