ARTICLE II
THE CREDIT FACILITIES

Subject to and upon the provisions of this Agreement, the Lender establishes a revolving credit facility in favor of the Borrower. The aggregate of all advances under the Revolving Credit Facility is sometimes referred to in this Agreement as the “Revolving Loan”.

The principal amount of Forty Million Dollars ($40,000,000) is the “Revolving Credit Committed Amount”. If at any time the unpaid principal balance of the Revolving Loan exceeds the Revolving Credit Committed Amount in effect from time to time, the Borrower shall pay such excess to the Lender ON DEMAND.

During the Revolving Credit Commitment Period, the Borrower may request advances under the Revolving Credit Facility in accordance with the provisions of this Agreement; provided that after giving effect to the Borrower’s request the aggregate outstanding principal balance of the Revolving Loan and all Letter of Credit Obligations would not exceed the Revolving Credit Committed Amount.

Unless sooner paid, the unpaid Revolving Loan, together with interest accrued and unpaid thereon, and all other Obligations shall be due and payable in full on the Revolving Credit Expiration Date.

The Borrower may borrow under the Revolving Credit Facility on any Business Day. Advances under the Revolving Loan shall be deposited to a demand deposit account of the Borrower with the Lender (or an Affiliate of the Lender) or shall be otherwise applied as directed by the Borrower, which direction the Lender may require to be in writing. Not later than 12:00 noon. (Eastern Time) on the date of the requested borrowing, the Borrower shall give the Lender oral or written notice (a “Loan Notice”) of the amount and (if requested by the Lender) the purpose of the requested borrowing. Any oral Loan Notice shall be confirmed in writing by the Borrower within three (3) Business Days after the making of the requested advance under the Revolving Loan. Each Loan Notice shall be irrevocable.

In addition, the Borrower hereby irrevocably authorizes the Lender at any time and from time to time, without further request from or notice to the Borrower, to make advances under the Revolving Loan, which the Lender, in its sole and absolute discretion, deems necessary or appropriate to protect the interests of the Lender, including, without limitation, advances and reserves under the Revolving Loan made to cover debit balances in the Revolving Loan Account, principal of, and/or interest on, any Loan, the Obligations (including, without limitation, any Letter of Credit Obligations), and/or Enforcement Costs, prior to, on, or after the termination of other advances under this Agreement, regardless of whether the outstanding principal amount of the Revolving Loan that the Lender may advance or reserve hereunder exceeds the Revolving Credit Committed Amount.

The obligation of the Borrower to pay the Revolving Loan, with interest, shall be evidenced by a promissory note (as from time to time extended, amended, restated, supplemented or otherwise modified, the “Revolving Credit Note”) substantially in the form of EXHIBIT “A” attached hereto and made a part hereof, with appropriate insertions. The Revolving Credit Note shall be dated as of the Closing Date, shall be payable to the order of the Lender at the times provided in the Revolving Credit Note, and shall be in the principal amount of the Revolving Credit Committed Amount. The Borrower acknowledges and agrees that, if the outstanding principal balance of the Revolving Loan outstanding from time to time exceeds the face amount of the Revolving Credit Note, the excess shall bear interest at the Post-Default Rate for the Revolving Loan and shall be payable, with accrued interest, ON DEMAND. The Revolving Credit Note shall not operate as a novation of any of the Obligations or nullify, discharge, or release any such Obligations or the continuing contractual relationship of the parties hereto in accordance with the provisions of this Agreement.

The Borrower shall have the option, at any time and from time to time, to prepay (each a “Revolving Loan Optional Prepayment” and collectively the “Revolving Loan Optional Prepayments”) the Revolving Loan, in whole or in part without premium or penalty.

If so directed by the Lender, the Borrower will deposit, or cause to be deposited, all Items of Payment to a bank account designated by the Lender and from which the Lender alone has power of access and withdrawal (the “Collateral Account”). Each deposit shall be made not later than the next Business Day after the date of receipt of the Items of Payment. The Items of Payment shall be deposited in precisely the form received, except for the endorsements of the Borrower where necessary to permit the collection of any such Items of Payment, the Borrower hereby agreeing to make such endorsement. In the event the Borrower fails to do so, the Lender is hereby authorized by the Borrower to make the endorsement in the name of the Borrower. Prior to such a deposit, the Borrower will not commingle any Items of Payment with any of the Borrower’s other funds or property, but will hold them separate and apart in trust and for the account of the Lender.

In addition, if so directed by the Lender, the Borrower shall direct the mailing of all Items of Payment from its Account Debtors to a post-office box designated by the Lender, or to such other additional or replacement post-office boxes pursuant to the request of the Lender from time to time (collectively, the “Lockbox”). The Lender shall have unrestricted and exclusive access to the Lockbox.

The Borrower hereby authorizes the Lender to inspect all Items of Payment, endorse all Items of Payment in the name of the Borrower, and deposit such Items of Payment in the Collateral Account. The Lender reserves the right, exercised in its sole and absolute discretion from time to time, to provide to the Collateral Account credit prior to final collection of an Item of Payment and to disallow credit for any Item of Payment which is unsatisfactory to the Lender. In the event Items of Payment are returned to the Lender for any reason whatsoever, the Lender may, in the exercise of its discretion from time to time, forward such Items of Payment a second time. Any returned Items of Payment shall be charged back to the Collateral Account, the Revolving Loan Account, or other account, as appropriate.

The Lender will apply the whole or any part of the collected funds credited to the Collateral Account against the Revolving Loan (or with respect to Items of Payment that are not proceeds of Accounts or after a Default or Event of Default, against any of the Obligations) or credit such collected funds to a depository account of the Borrower with the Lender (or an Affiliate of the Lender), the order and method of such application to be in the reasonable discretion of the Lender.

The Lender will establish and maintain a loan account on its books (the “Revolving Loan Account”) to which the Lender will (a) debit (i) the principal amount of each advance of the Revolving Loan made by the Lender hereunder as of the date made, (ii) the amount of any interest accrued on the Revolving Loan as and when due, and (iii) any other amounts due and payable by the Borrower to the Lender from time to time under the provisions of this Agreement in connection with the Revolving Loan, including, without limitation, Enforcement Costs, Fees, late charges, and service, collection and audit fees, as and when due and payable, and (b) credit all payments made by the Borrower to the Lender on account of the Revolving Loan as of the date made including, without limitation, funds credited to the Revolving Loan Account from the Collateral Account. The Lender may debit the Revolving Loan Account for the amount of any Item of Payment that is returned to the Lender unpaid. All credit entries to the Revolving Loan Account are conditional and shall be readjusted as of the date made if final and indefeasible payment is not received by the Lender in cash or solvent credits. Any and all periodic or other statements or reconciliations, and the information contained in those statements or reconciliations, of the Revolving Loan Account shall be final, binding and conclusive upon the Borrower in all respects, absent manifest error, unless the Lender receives specific written objection thereto from the Borrower within thirty (30) Business Days after such statement or reconciliation shall have been received by the Borrower.

The Borrower shall pay to the Lender a quarterly revolving credit facility fee (collectively, the “Revolving Credit Unused Line Fees” and individually, a “Revolving Credit Unused Line Fee”) in an amount equal to one quarter of one percent (1/4%) per annum of the average daily unused portion of the Revolving Credit Committed Amount in effect from time to time accruing during each calendar quarter. The accrued and unpaid portion of the Revolving Credit Unused Line Fee shall be paid by the Borrower to the Lender on the first day of each calendar quarter, commencing on the first such date following the date hereof, and on the Revolving Credit Termination Date.

Subject to and upon the provisions of this Agreement, and as a part of the Revolving Credit Commitment, the Borrower, upon the prior approval of Agent, may obtain standby or commercial letters of credit (as the same may from time to time be amended, supplemented or otherwise modified, each a “Letter of Credit” and collectively the “Letters of Credit”) from Lender from time to time from the Closing Date until the Business Day preceding the Revolving Credit Termination Date. The Borrower will not be entitled to obtain a Letter of Credit hereunder unless (a) after giving effect to the request, the outstanding principal balance of the Revolving Loan and of the Letter of Credit Obligations would not exceed the Revolving Credit Committed Amount (b) the sum of the aggregate face amount of the then outstanding Letters of Credit (including the face amount of the requested Letter of Credit) does not exceed Fifteen Million Dollars ($15,000,000) (the “Letter of Credit Sublimit”) and (c) the expiration date of the requested Letter of Credit is not later than nine (9) months following the Revolving Credit Expiration Date.

Prior to or simultaneously with the opening of each Letter of Credit, and annually thereafter, the Borrower shall pay to Lender, a letter of credit fee (each a “Letter of Credit Fee” and collectively the “Letter of Credit Fees”) in an amount equal to one and one-half percent (1.5%) per annum of the face amount of said Letter of Credit at the time said Letter of Credit Fee is due. Each Letter of Credit Fee shall be paid in advance on each anniversary of the date the related Letter of Credit was issued. In addition, the Borrower shall pay to the Lender any and all additional issuance, negotiation, processing, transfer or other fees to the extent and as and when required by the provisions of any Letter of Credit Agreement. The Lender is authorized to deduct any payment due hereunder from the Borrower’s account #004122817025 issued by the Lender, on or after the date any Letter of Credit Fee is due. All Letter of Credit Fees and all such other additional fees are included in and are a part of the “Fees” payable by the Borrower under the provisions of this Agreement and are a part of the Obligations.

Each Letter of Credit shall (a) be opened pursuant to a Letter of Credit Agreement and (b) expire on a date not later than the Business Day preceding the Revolving Credit Expiration Date; provided, however, if any Letter of Credit does have an expiration date later than the Business Day preceding the Revolving Credit Termination Date (each a “Post-Expiration Date Letter of Credit” and collectively, the “Post-Expiration Date Letters of Credit”), effective as of the Business Day preceding the Revolving Credit Termination Date and without prior notice to or the consent of the Borrower, the Lender shall make advances under the Revolving Loan for the account of the Borrower in the aggregate face amount of all such Letters of Credit. The Lender shall deposit the proceeds of such advances into one or more non-interest bearing accounts with and in the name of the Lender and over which the Lender alone shall have exclusive power of access and withdrawal (collectively, the “Letter of Credit Cash Collateral Account”). The Letter of Credit Cash Collateral Account is to be held by the Lender as additional collateral and security for any Letter of Credit Obligations relating to the Post-Expiration Date Letters of Credit. The Borrower hereby assigns, pledges, grants and sets over to the Lender a first priority security interest in, and Lien on, all of the funds on deposit in the Letter of Credit Cash Collateral Account, together with any and all Proceeds and products thereof as additional collateral and security for the Letter of Credit Obligations relating to the Post-Expiration Date Letters of Credit. The Borrower acknowledges and agrees that the Lender shall be entitled to fund any draw or draft on any Post-Expiration Date Letter of Credit from the monies on deposit in the Letter of Credit Cash Collateral Account without notice to or consent of the Borrower or the Lender. The Borrower further acknowledges and agrees that the Lender’s election to fund any draw or draft on any Post-Expiration Date Letter of Credit from the Letter of Credit Cash Collateral shall in no way limit, impair, lessen, reduce, release or otherwise adversely affect the Borrower’s obligation to pay any Letter of Credit Obligations under or relating to the Post-Expiration Date Letters of Credit. At such time as all Post-Expiration Date Letters of Credit have expired and all Letter of Credit Obligations relating to the Post-Expiration Date Letters of Credit have been paid in full, the Lender agrees to apply the amount of any remaining funds on deposit in the Letter of Credit Cash Collateral Account to the then unpaid balance of the Obligations under the Revolving Credit Facility in such order and manner as the Lender shall determine in its sole and absolute discretion in accordance with the provisions of this Agreement.

The aggregate face amount of all Letters of Credit at any one time outstanding and issued by the Lender pursuant to the provisions of this Agreement, including, without limitation, any and all Post-Expiration Date Letters of Credit, plus the amount of any unpaid Letter of Credit Fees accrued or scheduled to accrue thereon, and less the aggregate amount of all drafts issued under or purporting to have been issued under such Letters of Credit that have been paid by the Lender and for which the Lender has been reimbursed by the Borrower in full in accordance with Section 2.2.5 (Payments of Letters of Credit) and the Letter of Credit Agreements, and for which the Lender has no further obligation or commitment to restore all or any portion of the amounts drawn and reimbursed, is herein called the “Outstanding Letter of Credit Obligations”.

The Borrower shall give the Lender written notice at least five (5) Business Days prior to the date on which the Borrower desires the Lender to issue a Letter of Credit. The Borrower shall give the Lender written notice at least three (3) Business Days prior to the date on which a Letter of Credit is requested to be opened of their request for a Letter of Credit. Such notice shall be accompanied by a duly executed and delivered Letter of Credit Agreement. Upon receipt of the Letter of Credit Agreement and the Letter of Credit Fee, the Lender shall process such Letter of Credit Agreement in accordance with its customary procedures and open such Letter of Credit on the Business Day specified in such notice.

The Borrower hereby promises to pay to the Lender, ON DEMAND and in United States Dollars, the following which are herein collectively referred to as the “Current Letter of Credit Obligations”:

(a) the amount which the Lender has paid or will be required to pay under each draft or draw on a Letter of Credit, whether such demand be in advance of the Lender’s payment or for reimbursement for such payment;

(b) any and all reasonable charges and expenses which the Lender may pay or incur relative to the Letter of Credit and/or such draws or drafts; and

(c) interest on the amounts described in (a) and (b) not paid by the Borrower as and when due and payable under the provisions of (a) and (b) above from the day the same are due and payable until paid in full at a rate per annum equal to the then current highest rate of interest on the Revolving Loan.

In addition, the Borrower hereby promises to pay any and all other Letter of Credit Obligations as and when due and payable in accordance with the provisions of this Agreement and the Letter of Credit Agreements. The obligation of the Borrower to pay Current Letter of Credit Obligations and all other Letter of Credit Obligations shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Borrower or any other account party may have or have had against the beneficiary of such Letter of Credit, the Lender, or any other Person, including, without limitation, any defense based on the failure of any draft or draw to conform to the terms of such Letter of Credit, any draft or other document proving to be forged, fraudulent or invalid, or the legality, validity, regularity or enforceability of such Letter of Credit, any draft or other documents presented with any draft, any Letter of Credit Agreement, this Agreement, or any of the other Financing Documents, all whether or not the Lender had actual or constructive knowledge of the same, and irrespective of any Collateral, security or guarantee therefore or right of offset with respect thereto and irrespective of any other circumstances whatsoever which constitutes, or might be construed to constitute, an equitable or legal discharge of the Borrower for any Letter of Credit Obligations, in bankruptcy or otherwise; provided, however, that the Borrower shall not be obligated to reimburse the Lender for any wrongful payment under such Letter of Credit made as a result of the Lender’s willful misconduct. The obligation of the Borrower to pay the Letter of Credit Obligations shall not be conditioned or contingent upon the pursuit by the Lender or any other Person at any time of any right or remedy against any Person which may be or become liable in respect of all or any part of such obligation or against any Collateral, security or guarantee therefore or right of offset with respect thereto.

The Letter of Credit Obligations shall continue to be effective, or be reinstated, as the case may be, if at any time payment of all or any portion of the Letter of Credit Obligations is rescinded or must otherwise be restored or returned by the Lender upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of any Person, or upon or as a result of the appointment of a receiver, intervenor, or conservator of, or trustee or similar officer for, any Person, or any substantial part of such Person’s property, all as though such payments had not been made.

If any change in any law or regulation or in the interpretation thereof by any court or other Governmental Authority charged with the administration thereof shall either (a) impose, modify or deem applicable any reserve, special deposit or similar requirement against Letters of Credit issued by the Lender, or (b) impose on the Lender any other condition regarding this Agreement or any Letter of Credit, and the result of any event referred to in clauses (a) or (b) above shall be to increase the cost to the Lender of issuing, maintaining or extending the Letter of Credit or the cost to Lender of funding any obligation under or in connection with the Letter of Credit, then, upon demand by the Lender, the Borrower shall immediately pay to the Lender from time to time as specified by the Lender, additional amounts which shall be sufficient to compensate the Lender for such increased cost, together with interest on each such amount from the date demanded until payment in full thereof at a rate per annum equal to the then highest current rate of interest on the Revolving Loan. A certificate as to such increased cost incurred by the Lender, submitted by the Lender to the Borrower, shall be conclusive, absent manifest error.

The Borrower hereby instructs the Lender to pay any draft complying with the terms of any Letter of Credit irrespective of any instructions of the Borrower to the contrary. The Borrower assumes all risks of the acts and omissions of the beneficiary and other users of any Letter of Credit. The Lender and its respective branches, Affiliates and/or correspondents shall not be responsible for and the Borrower hereby indemnifies and holds the Lender and its branches, Affiliates and/or correspondents harmless from and against all liability, loss and expense (including reasonable attorney’s fees and costs) incurred by the Lender and/or its respective branches, Affiliates and/or correspondents relative to and/or as a consequence of (a) any failure by the Borrower to perform the agreements hereunder and under any Letter of Credit Agreement, (b) any Letter of Credit Agreement, this Agreement, any Letter of Credit and any draft, draw and/or acceptance under or purported to be under any Letter of Credit, (c) any action taken or omitted by the Lender and/or any of its respective branches, Affiliates and/or correspondents at the request of the Borrower, (d) any failure or inability to perform in accordance with the terms of any Letter of Credit by reason of any control or restriction rightfully or wrongfully exercised by any de facto or de jure Governmental Authority, group or individual asserting or exercising governmental or paramount powers, and/or (e) any consequences arising from causes beyond the control of the Lender and/or any of its respective branches, Affiliates and/or correspondents.

Except for willful misconduct, the Lender and its respective branches, Affiliates and/or correspondents, shall not be liable or responsible in any respect for any (a) error, omission, interruption or delay in transmission, dispatch or delivery of any one or more messages or advices in connection with any Letter of Credit, whether transmitted by cable, telegraph, mail or otherwise and despite any cipher or code which may be employed, and/or (b) action, inaction or omission which may be taken or suffered by it or them in good faith or through inadvertence in identifying or failing to identify any beneficiary or otherwise in connection with any Letter of Credit.

Any Letter of Credit may be amended, modified or revoked only upon the receipt by the Lender from the Borrower and the beneficiary (including any transferee and/or assignee of the original beneficiary), of a written consent and request therefore.

If any Laws, order of court and/or ruling or regulation of any Governmental Authority of the United States (or any state thereof) and/or any country other than the United States permits a beneficiary under a Letter of Credit to require the Lender and/or any of its respective branches, Affiliates and/or correspondents to pay drafts under or purporting to be under a Letter of Credit after the expiration date of the Letter of Credit, the Borrower shall reimburse the Lender, as appropriate, for any such payment pursuant to provisions of Section 2.2.6 (Change in Law; Increased Cost).

Except as may otherwise be specifically provided in a Letter of Credit or Letter of Credit Agreement, the laws of the State and the Uniform Customs and Practice for Documentary Credits, 1993 Revision, International Chamber of Commerce Publication No. 500 shall govern the Letters of Credit. The Laws, rules, provisions and regulations of the Uniform Customs and Practice for Documentary Credits are hereby incorporated by reference. In the event of a conflict between the Uniform Customs and Practice for Documentary Credits and the laws of the State, the Uniform Customs and Practice for Documentary Credits shall prevail.

Each Borrower hereby represents and warrants to the Lender that each of them will derive benefits, directly and indirectly, from each Letter of Credit and from each Loan, both in their separate capacity and as a member of the integrated group to which each of the Borrowers belong and because the successful operation of the integrated group is dependent upon the continued successful performance of the functions of the integrated group as a whole, because (a) the terms of the consolidated financing provided under this Agreement are more favorable than would otherwise be obtainable by the Borrowers individually and (b) Borrowers’ additional administrative and other costs and reduced flexibility associated with individual financing arrangements which would otherwise be required if obtainable would substantially reduce the value to the Borrowers of the financing. The Borrowers in the discretion of their respective managements are to agree among themselves as to the allocation of the benefits of Letters of Credit and the proceeds of the Loan, provided, however, that the Borrowers shall be deemed to have represented and warranted to the Lender at the time of allocation that each benefit and use of proceeds is a Permitted Use.

For administrative convenience, each Borrower hereby irrevocably appoints Argon as the Borrower’s attorney-in-fact, with power of substitution (with the prior written consent of the Lender in the exercise of its sole and absolute discretion), in the name of Argon or in the name of the Borrower or otherwise to take any and all actions with respect to the this Agreement, the other Financing Documents, the Obligations and/or the Collateral (including, without limitation, the Proceeds thereof) as Argon may so elect from time to time, including, without limitation, actions to (i) request advances under the Loan, apply for and direct the benefits of Letters of Credits, and direct the Lender to disburse or credit the proceeds of any Loan directly to an account of Argon, any one or more of the Borrowers or otherwise, which direction shall evidence the making of such Loan and shall constitute the acknowledgment by each of the Borrowers of the receipt of the proceeds of such Loan or the benefit of such Letter of Credit, (ii) enter into, execute, deliver, amend, modify, restate, substitute, extend and/or renew this Agreement, any Additional Borrower Joinder Supplement, any other Financing Documents, security agreements, mortgages, deposit account agreements, instruments, certificates, waivers, letter of credit applications, releases, documents and agreements from time to time, and (iii) endorse any check or other item of payment in the name of the Borrower or in the name of Argon. The foregoing appointment is coupled with an interest, cannot be revoked without the prior written consent of the Lender, and may be exercised from time to time through Argon’s duly authorized officer, officers or other Person or Persons designated by Argon to act from time to time on behalf of Argon.

Each of the Borrowers hereby irrevocably authorizes the Lender to make Loans to any one or more of the Borrowers, and hereby irrevocably authorizes the Lender to issue or cause to be issued Letters of Credit for the account of any or all of the Borrowers, pursuant to the provisions of this Agreement upon the written, oral or telephone request of any one or more of the Persons who is from time to time a Responsible Officer of a Borrower under the provisions of the most recent certificate of corporate resolutions and/or incumbency of the Borrowers on file with the Lender and also upon the written, oral or telephone request of any one of the Persons who is from time to time a Responsible Officer of Argon under the provisions of the most recent certificate of corporate resolutions and/or incumbency for Argon on file with the Lender.

The Lender assumes no responsibility or liability for any errors, mistakes, and/or discrepancies in the oral, telephonic, written or other transmissions of any instructions, orders, requests and confirmations between the Lender and the Borrowers in connection with the Credit Facilities, any Loan, any Letter of Credit or any other transaction in connection with the provisions of this Agreement. Without implying any limitation on the joint and several nature of the Obligations, the Lender agrees that, notwithstanding any other provision of this Agreement, the Borrowers may create reasonable inter-company indebtedness between or among the Borrowers with respect to the allocation of the benefits and proceeds of the advances and Credit Facilities under this Agreement. The Borrowers agree among themselves, and the Lender consents to that agreement, that each Borrower shall have rights of contribution from all of the other Borrowers to the extent such Borrower incurs Obligations in excess of the proceeds of the Loans received by, or allocated to purposes for the direct benefit of, such Borrower. All such indebtedness and rights shall be, and are hereby agreed by the Borrowers to be, subordinate in priority and payment to the indefeasible repayment in full in cash of the Obligations, and, unless the Lender agrees in writing otherwise, shall not be exercised or repaid in whole or in part until all of the Obligations have been indefeasibly paid in full in cash. The Borrowers agree that all of such inter-company indebtedness and rights of contribution are part of the Collateral and secure the Obligations. Each Borrower hereby waives all rights of counterclaim, recoupment and offset between or among themselves arising on account of that indebtedness and otherwise. Each Borrower shall not evidence the inter-company indebtedness or rights of contribution by note or other instrument, and shall not secure such indebtedness or rights of contribution with any Lien or security. Notwithstanding anything contained in this Agreement to the contrary, the amount covered by each Borrower under the Obligations (including, without limitation, Section 2.3.9 (Guaranty) shall be limited to an aggregate amount (after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Borrower in respect of the Obligations) which, together with other amounts owing by such Borrowers to the Lender under the Obligations, is equal to the largest amount that would not be subject to avoidance under the Bankruptcy Code or any applicable provisions of any applicable, comparable state or other Laws.

The proceeds of each advance under the Loan shall be used by the Borrower for Permitted Uses, and for no other purposes except as may otherwise be agreed by the Lender in writing. The Borrower shall use the proceeds of the Loan promptly.

The Borrower shall pay to the Lender an annual administrative fee (each an “Administrative Fee” and collectively, the “Administrative Fees”) for administrative services performed in conjunction with the Revolving Credit Facility. The Administrative Fee shall be payable each year in advance on the first (1^st) day of each March until the Revolving Credit Termination Date and equal to the product of (a) 0.0015 multiplied by (b) the Revolving Credit Committed Amount; provided that if the Borrower and the Lender agree to increase the Revolving Credit Committed Amount during the course of any year, the Borrower shall pay to the Lender at the time of such increase, an additional amount equal to the product of (x) 0.0015 multiplied by (y) such increase in the Revolving Credit Committed Amount.

All applicable Fees and interest shall be calculated on the basis of a year of 360 days for the actual number of days elapsed.

All payments of the Obligations, including, without limitation, principal, interest, Prepayments, and Fees, shall be paid by the Borrower without setoff, recoupment or counterclaim to the Lender in immediately available funds not later than 12:00 p.m. (Eastern Time) on the due date of such payment. All payments received by the Lender after such time shall be deemed to have been received by the Lender for purposes of computing interest and Fees and otherwise as of the next Business Day. Payments shall not be considered received by the Lender until such payments are paid to the Lender in immediately available funds to the Lender’s principal office in McLean, Virginia or at such other location as the Lender may at any time and from time to time notify the Borrower. Alternatively, at its sole discretion, the Lender may charge any deposit account of the Borrower at the Lender or any Affiliate of the Lender with all or any part of any amount due to the Lender under this Agreement or any of the other Financing Documents to the extent that the Borrower shall have not otherwise tendered payment to the Lender. All payments shall be applied first to any unpaid Fees, second to any and all accrued and unpaid late charges and Enforcement Costs, third to any and all accrued and unpaid interest on the Obligations, and then to the then unpaid principal balance of the Obligations, all in such order and manner as shall be determined by the Lender in its sole and absolute discretion.

The Borrower hereby grants to the Lender as additional collateral and security for all of the Obligations, a continuing Lien on any and all monies, Investment Property, and other property of the Borrower and the proceeds thereof, now or hereafter held or received by or in transit to, the Lender, and/or any Affiliate of the Lender, from or for the account of, the Borrower, and also upon any and all deposit accounts (general or special) and credits of the Borrower, if any, with the Lender or any Affiliate of the Lender, at any time existing, excluding any deposit accounts held by the Borrower in its capacity as trustee for Persons who are not Affiliates of the Borrower. Without implying any limitation on any other rights the Lender may have under the Financing Documents or applicable Laws, during the continuance of an Event of Default, the Lender is hereby authorized by the Borrower at any time and from time to time, without notice to the Borrower, to set off, appropriate and apply any or all items hereinabove referred to against all Obligations then outstanding (whether or not then due), all in such order and manner as shall be determined by the Lender in its sole and absolute discretion.

In the event that the Lender shall have determined in good faith that (a) the adoption of any Capital Adequacy Regulation, or (b) any change in any Capital Adequacy Regulation or in the interpretation or application thereof or (c) compliance by the Lender or any corporation controlling the Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any central bank or Governmental Authority, does or shall have the effect of reducing the rate of return on the capital of the Lender or any corporation controlling the Lender, as a consequence of the obligations of the Lender hereunder to a level below that which the Lender or any corporation controlling the Lender would have achieved but for such adoption, change or compliance (taking into consideration the policies of the Lender and the corporation controlling the Lender, with respect to capital adequacy) by an amount deemed by the Lender, in its discretion, to be material, then from time to time, after submission by the Lender to the Borrower of a written request therefore and a statement of the basis for such determination, the Borrower shall pay to the Lender such additional amount or amounts in order to compensate the Lender or its controlling corporation for any such reduction.

The Borrower may request and the Lender or its affiliates may, in their sole and absolute discretion, provide ACH Transactions and Swap Contracts. In the event the Borrower requests Lender or its affiliates to procure ACH Transactions or Swap Contracts, then the Borrower agrees to indemnify and hold the Lender or its affiliates harmless from any and all obligations now or hereafter owing to the Lender or its affiliates. The Borrower agrees to pay the Lender or its affiliates all amounts owing to the Lender or its affiliates pursuant to ACH Transactions and Swap Contracts. In the event the Borrower shall not have paid to the Lender or its affiliates such amounts, the Lender may cover such amounts by an advance under the Revolving Loan, which advance shall be deemed to have been requested by the Borrower. The Borrower acknowledges and agrees that the obtaining of ACH Transactions and Swap Contracts from the Lender or its Affiliates (a) is in the sole and absolute discretion of the Lender or its Affiliates and (b) is subject to all rules and regulations of the Lender or its Affiliates.

(a) Each Borrower hereby unconditionally and irrevocably, guarantees to the Lender:

(i) the due and punctual payment in full (and not merely the collectibility) by the other Borrowers of the Obligations, including unpaid and accrued interest thereon, in each case when due and payable, all according to the terms of this Agreement, the Notes and the other Financing Documents;

(ii) the due and punctual payment in full (and not merely the collectibility) by the other Borrowers of all other sums and charges which may at any time be due and payable in accordance with this Agreement, the Notes or any of the other Financing Documents;

(iii) the due and punctual performance by the other Borrowers of all of the other terms, covenants and conditions contained in the Financing Documents; and

(iv) all the other Obligations of the other Borrowers.

(b) The obligations and liabilities of each Borrower as a guarantor under this Section 2.3.9 shall be absolute and unconditional and joint and several, irrespective of the genuineness, validity, priority, regularity or enforceability of this Agreement, any of the Notes or any of the Financing Documents or any other circumstance which might otherwise constitute a legal or equitable discharge of a surety or guarantor. Each Borrower in its capacity as a guarantor expressly agrees that the Lender may, in its sole and absolute discretion, without notice to or further assent of such Borrower and without in any way releasing, affecting or in any way impairing the joint and several obligations and liabilities of such Borrower as a guarantor hereunder:

(i) waive compliance with, or any defaults under, or grant any other indulgences under or with respect to any of the Financing Documents;

(ii) modify, amend, change or terminate any provisions of any of the Financing Documents;

(iii) grant extensions or renewals of or with respect to the Credit Facilities, the Notes or any of the other Financing Documents;

(iv) effect any release, subordination, compromise or settlement in connection with this Agreement, any of the Notes or any of the other Financing Documents;

(vi) make advances for the purpose of performing any term, provision or covenant contained in this Agreement, any of the Notes or any of the other Financing Documents with respect to which the Borrowers shall then be in default;

(vii) make future advances pursuant to this Agreement or any of the other Financing Documents;

(viii) assign, pledge, hypothecate or otherwise transfer the Commitments, the Obligations, the Notes, any of the other Financing Documents or any interest therein, all as and to the extent permitted by the provisions of this Agreement;

(ix) deal in all respects with the other Borrowers as if this Section 2.3.9 were not in effect;

(x) effect any release, compromise or settlement with any of the other Borrowers, whether in their capacity as a Borrower or as a guarantor under this Section 2.3.9, or any other guarantor; and

(xi) provide debtor-in-possession financing or allow use of cash collateral in proceedings under the Bankruptcy Code, it being expressly agreed by all Borrowers that any such financing and/or use would be part of the Obligations.

(c) The obligations and liabilities of each Borrower, as guarantor under this Section 2.3.9, shall be primary, direct and immediate, shall not be subject to any counterclaim, recoupment, set off, reduction or defense based upon any claim that a Borrower may have against any one or more of the other Borrowers, the Lender, and/or any other guarantor and shall not be conditional or contingent upon pursuit or enforcement by the Lender of any remedies it may have against the Borrowers with respect to this Agreement, the Notes or any of the other Financing Documents, whether pursuant to the terms thereof or by operation of law. Without limiting the generality of the foregoing, the Lender shall not be required to make any demand upon any of the Borrowers, or to sell the Collateral or otherwise pursue, enforce or exhaust its remedies against the Borrowers or the Collateral either before, concurrently with or after pursuing or enforcing its rights and remedies hereunder. Any one or more successive or concurrent actions or proceedings may be brought against each Borrower under this Section 2.3.9, either in the same action, if any, brought against any one or more of the Borrowers or in separate actions or proceedings, as often as the Lender may deem expedient or advisable. Without limiting the foregoing, it is specifically understood that any modification, limitation or discharge of any of the liabilities or obligations of any one or more of the Borrowers, any other guarantor or any obligor under any of the Financing Documents, arising out of, or by virtue of, any bankruptcy, arrangement, reorganization or similar proceeding for relief of debtors under federal or state law initiated by or against any one or more of the Borrowers, in their respective capacities as borrowers and guarantors under this Section 2.3.9, or under any of the Financing Documents shall not modify, limit, lessen, reduce, impair, discharge, or otherwise affect the liability of each Borrower under this Section 2.3.9 in any manner whatsoever, and this Section 2.3.9 shall remain and continue in full force and effect. It is the intent and purpose of this Section 2.3.9 that each Borrower shall and does hereby waive all rights and benefits which might accrue to any other guarantor by reason of any such proceeding, and the Borrowers agree that they shall be liable for the full amount of the obligations and liabilities under this Section 2.3.9, regardless of, and irrespective to, any modification, limitation or discharge of the liability of any one or more of the Borrowers, any other guarantor or any obligor under any of the Financing Documents, that may result from any such proceedings.

(d) Each Borrower, as guarantor under this Section 2.3.9, hereby unconditionally, jointly and severally, irrevocably and expressly waives:

(i) presentment and demand for payment of the Obligations and protest of non-payment;

(ii) notice of acceptance of this Section 2.3.9 and of presentment, demand and protest thereof;

(iii) notice of any default hereunder or under the Notes or any of the other Financing Documents and notice of all indulgences;

(iv) notice of any increase in the amount of any portion of or all of the indebtedness guaranteed by this Section 2.3.9;

(v) demand for observance, performance or enforcement of any of the terms or provisions of this Section 2.3.9, the Notes or any of the other Financing Documents;

(vi) all errors and omissions in connection with the Lender’s administration of all indebtedness guaranteed by this Section 2.3.9, except errors and omissions resulting from acts of bad faith;

(vii) any right or claim of right to cause a marshalling of the assets of any one or more of the other Borrowers;

(viii) any act or omission of the Lender which changes the scope of the risk as guarantor hereunder; and

(ix) all other notices and demands otherwise required by law which the Borrower may lawfully waive.

Within ten (10) days following any request of the Lender so to do, each Borrower will furnish the Lender and such other persons as the Lender may direct with a written certificate, duly acknowledged stating in detail whether or not any credits, offsets or defenses exist with respect to this Section 2.3.9.

Subject to and upon the provisions of this Agreement, the Lender establishes a guidance line facility in favor of the Borrower. The aggregate of all advances under the Guidance Line Facility is sometimes referred to in this Agreement as the “Guidance Loan”.

The maximum principal amount of Twenty Million and No/100 Dollars ($20,000,000.00) is the “Guidance Line Amount”.

During the Guidance Line Availability Period, the Borrower may request advances under the Guidance Line Facility in accordance with the provisions of this Agreement; provided, that after giving effect to the Borrower’s request the aggregate outstanding principal balance of the Guidance Loan would not exceed the Guidance Line Amount and, provided further, that the Lender may elect, in its sole and absolute discretion exercised from time to time, to approve or to deny the Borrower’s request for an advance under the Guidance Line Facility, notwithstanding the occurrence or non-occurrence of a Default or an Event of Default.

From and after the Guidance Line Termination Date, the Borrower shall not be entitled to request any additional advances under the Guidance Line Facility. Unless sooner paid, the unpaid Guidance Loan, together with interest accrued and unpaid thereon, and all other Obligations shall be due and payable in full at maturity of the Guidance Line Note.

Notwithstanding anything to the contrary contained herein, no provision of this Agreement and no course of dealing shall impose upon the Lender any obligation to approve any request for an advance under the Guidance Line Facility to the Borrower. The Borrower acknowledges and agrees that it fully understands that it is not relying on the Lender to make or continue to make any advance under the Guidance Loan Facility for any purpose whatsoever.

Subject to the limitations set forth in and the consent of the Lender described in Section 2.5.1 hereof, the Borrower may borrow under the Guidance Line Facility on any Business Day. Advances approved under the Guidance Loan shall be deposited to a demand deposit account of the Borrower with the Lender (or an Affiliate of the Lender) or shall be otherwise applied as directed by the Borrower, which direction the Lender may require to be in writing. No later than 12:00 noon (Eastern Time) on the date of the requested borrowing under the Guidance Loan, the Borrower shall give the Lender a Loan Notice of the amount and (if requested by the Lender) the purpose of the requested borrowing and shall designate the requested borrowing as a borrowing under the Guidance Loan. Any oral Loan Notice shall be confirmed in writing by the Borrower within three (3) Business Days after the making of the requested advance under the Guidance Loan. Each Loan Notice shall be irrevocable.

The obligation of the Borrower to pay the Guidance Loan, with interest, shall be evidenced by a promissory note (as from time to time extended, amended, restated, supplemented or otherwise modified, the “Guidance Line Note”), in form and substance satisfactory to the Lender. The Guidance Line Note shall be dated as of the Closing Date, shall be payable to the order of the Lender at the times provided in the Guidance Line Note, and shall be in the principal amount of the Guidance Line Amount. The Guidance Line Note shall not operate as a novation of any of the Obligations or nullify, discharge, or release any such Obligations or the continuing contractual relationship of the parties hereto in accordance with the provisions of this Agreement.

The Borrower shall have the option at any time and from time to time to prepay (each a “Guidance Loan Optional Prepayment” and collectively the “Guidance Loan Optional Prepayments”) the Guidance Loan, in whole or in part without premium or penalty.

(a) Subject to Section 2.5.1(b), each Loan shall bear interest until maturity (whether by acceleration, declaration, extension or otherwise) at a fluctuating rate per year which at all times shall be equal to the BBA LIBOR Daily Floating Rate plus one hundred seventy-five (175) basis points per annum (the “Interest Rate”).

(b) Notwithstanding the foregoing, following the occurrence and during the continuance of an Event of Default, at the option of the Lender, all Loans and all other Obligations shall bear interest at the Post-Default Rate.

Unpaid and accrued interest on the Loans shall be paid monthly, in arrears, on the first day of each calendar month (each, an “Interest Payment Date”), commencing on the first such date after the date of this Agreement, and on the first day of each calendar month thereafter, and at maturity (whether by acceleration, declaration, extension or otherwise).

Except as otherwise disclosed on Schedule 4.1.10 attached hereto and made a part hereof, there are no proceedings, actions or investigations pending or, so far as the Borrower knows, threatened before or by any court, arbitrator or any Governmental Authority which, in any one case or in the aggregate, if determined adversely to the interests of the Borrower or any Subsidiary, would have a material adverse effect on the business, properties, condition (financial or otherwise) or operations, present or prospective, of the Borrower.

The financial statements of the Borrower dated June 30, 2009, are complete and correct and fairly present the financial position of the Borrower and the results of its operations and transactions in its surplus accounts as of the date and for the period referred to and have been prepared in accordance with GAAP applied on a consistent basis throughout the period involved.

The Lender, or an agent designated by the Lender, shall be permitted to enter the premises of the Borrower and examine, audit and inspect the Collateral at any reasonable time and from time to time without notice. The Lender agrees to act in a commercially reasonable manner when inspecting the premises of the Borrower and when examining, auditing and/or inspecting the Collateral.

At its expense the Borrower will defend the title to the Collateral (and any part thereof), and will immediately execute, acknowledge and deliver any renewal, affidavit, deed, assignment, security agreement, certificate or other document which the Lender may require in order to perfect, preserve, maintain, continue, protect and/or extend the Lien granted to the Lender under this Agreement or under any of the other Financing Documents and the first priority of that Lien subject only to the Permitted Liens. The Borrower hereby authorizes the filing of any financing statement or continuation statement required under the Uniform Commercial Code. The Borrower will from time to time do whatever the Lender may require by way of obtaining, executing, delivering, and/or filing landlords’, mortgagees’ or bailees’ waivers, notices of assignment and other notices and amendments and renewals thereof and the Borrower will take any and all steps and observe such formalities as the Lender may require, in order to create and maintain a valid Lien upon, pledge of, or paramount security interest in, the Collateral, subject to the Permitted Liens. The Borrower shall pay to the Lender on demand all taxes, costs and expenses incurred by the Lender in connection with the preparation, execution, recording and filing of any such document or instrument. To the extent that the proceeds of any of the Accounts or Receivables of the Borrower are expected to become subject to the control of, or in the possession of, a party other than the Borrower or the Lender, the Borrower shall cause all such parties to execute and deliver on the Closing Date security documents or other documents as requested by the Lender and as may be necessary to evidence and/or perfect the security interest of the Lender in those proceeds. The Borrower hereby irrevocably appoints the Lender as the Borrower’s attorney-in-fact, with power of substitution, in the name of the Lender or in the name of the Borrower or otherwise, for the use and benefit of the Lender, but at the cost and expense of the Borrower and without notice to the Borrower, to execute and deliver any and all of the instruments and other documents and take any action which the Lender may require pursuant the foregoing provisions of this Section.

Any representation or warranty made in this Agreement or in any report, statement, schedule, certificate, opinion (including any opinion of counsel for the Borrower), financial statement or other document furnished in connection with this Agreement, any of the other Financing Documents, or the Obligations, shall prove to have been false or misleading when made (or, if applicable, when reaffirmed) in any material respect.

Unless adequately insured in the opinion of the Lender, the entry of a final judgment for the payment of money involving more than $250,000 against the Borrower, and the failure by the Borrower to discharge the same, or cause it to be discharged, within thirty (30) days from the date of the order, decree or process under which or pursuant to which such judgment was entered, or to secure a stay of execution pending appeal of such judgment.

Any execution or attachment shall be levied against the Collateral, or any part thereof, and such execution or attachment shall not be set aside, discharged or stayed within thirty (30) days after the same shall have been levied.

Default shall be made with respect to any Funded Debt (other than the Loan) if the effect of such default is to accelerate the maturity of such Funded Debt or to permit the holder or obligee thereof or other party thereto to cause any such Funded Debt to become due prior to its stated maturity.

The Borrower shall challenge the validity and binding effect of any provision of any of the Financing Documents or shall state its intention to make such a challenge of any of the Financing Documents or any of the Financing Documents shall for any reason (except to the extent permitted by its express terms) cease to be effective or to create a valid and perfected first priority Lien (except for Permitted Liens) on, or security interest in, any of the Collateral purported to be covered thereby.

The Lender in its reasonable discretion determines in good faith that a material adverse change has occurred in the financial condition of the Borrower.

The Lender in its reasonable discretion determines in good faith that an event has occurred which impairs the prospect of payment of the Obligations and/or the value of the Collateral.

The determination in good faith by the Lender that the security for the Obligations is inadequate.

Any change in control of the ownership of the Borrower. For purposes hereof, change in control of the ownership of the Borrower shall mean change of twenty percent (20%) or more of the aggregate of the ownership of the Borrower.

Default shall be made under any Government Contract, or any Government Contract is terminated for default by any Governmental Authority for any reason whatsoever, or if the Borrower is debarred or suspended, whether temporarily or permanently, by any Governmental Authority.

The Borrower shall liquidate, dissolve or terminate its existence or shall suspend or terminate a substantial portion of its business operations or any change occurs in the management or control of the Borrower without the prior written consent of the Lender.

The Borrower shall make any advance, loan, or extension of credit to or any payment on behalf of or guaranty any obligation of any Subsidiary in excess of $500,000 in the Aggregate without the Lender’s prior written consent.

An event occurs which gives the Lender the right or option to terminate any Swap Contract which is secured by the Collateral.

Upon the occurrence of any Default or Event of Default, the Lender may at any time thereafter exercise any one or more of the following rights, powers or remedies:

The Lender may declare the Obligations to be immediately due and payable, notwithstanding anything contained in this Agreement or in any of the other Financing Documents to the contrary, without presentment, demand, protest, notice of protest or of dishonor, or other notice of any kind, all of which the Borrower hereby waives.

The Lender may from time to time without notice to the Borrower suspend, terminate or limit any further loans or other extensions of credit under this Agreement and under any of the other Financing Documents. Further, upon the occurrence of an Event of Default or Default specified in Section 7.1.5 (Receiver; Bankruptcy) or Section 7.1.6 (Involuntary Bankruptcy, etc.), the Revolving Credit Commitment and any agreement in any of the Financing Documents to provide additional credit and/or to issue Letters of Credit shall immediately and automatically terminate and the unpaid principal amount of the Notes (with accrued interest thereon) and all other Obligations then outstanding, shall immediately become due and payable without further action of any kind and without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived by the Borrower.

The Lender shall have all of the rights and remedies of a secured party under the applicable Uniform Commercial Code and other applicable Laws. Upon demand by the Lender, the Borrower shall assemble the Collateral and make it available to the Lender, at a place designated by the Lender. The Lender or its agents may without notice from time to time enter upon the Borrower’s premises to take possession of the Collateral, to remove it, to render it unusable, to process it or otherwise prepare it for sale, or to sell or otherwise dispose of it.

Any written notice of the sale, disposition or other intended action by the Lender with respect to the Collateral which is sent by regular mail, postage prepaid, to the Borrower at the address set forth in Section 8.1 (Notices), or such other address of the Borrower which may from time to time be shown on the Lender’s records, at least ten (10) days prior to such sale, disposition or other action, shall constitute commercially reasonable notice to the Borrower. The Lender may alternatively or additionally give such notice in any other commercially reasonable manner. Nothing in this Agreement shall require the Lender to give any notice not required by applicable Laws.

If any consent, approval, or authorization of any state, municipal or other Governmental Authority or of any other Person or of any Person having any interest therein, should be necessary to effectuate any sale or other disposition of the Collateral, the Borrower agrees to execute all such applications and other instruments, and to take all other action, as may be required in connection with securing any such consent, approval or authorization.

The Borrower recognizes that the Lender may be unable to effect a public sale of all or a part of the Collateral consisting of Investment Property by reason of certain prohibitions contained in the Securities Act of 1933, as amended, and other applicable Federal and state Laws. The Lender may, therefore, in its discretion, take such steps as it may deem appropriate to comply with such Laws and may, for example, at any sale of the Collateral consisting of securities restrict the prospective bidders or purchasers as to their number, nature of business and investment intention, including, without limitation, a requirement that the Persons making such purchases represent and agree to the satisfaction of the Lender that they are purchasing such securities for their account, for investment, and not with a view to the distribution or resale of any thereof. The Borrower covenants and agrees to do or cause to be done promptly all such acts and things as the Lender may request from time to time and as may be necessary to offer and/or sell the securities or any part thereof in a manner which is valid and binding and in conformance with all applicable Laws. Upon any such sale or disposition, the Lender shall have the right to deliver, assign and transfer to the purchaser thereof the Collateral consisting of securities so sold.

In addition to all other rights and remedies provided hereunder or as shall exist at law or in equity from time to time, the Lender may (but shall be under no obligation to), without notice to the Borrower, and the Borrower hereby irrevocably appoints the Lender as its attorney-in-fact, with power of substitution, in the name of the Lender and/or in the name of the Borrower or otherwise, for the use and benefit of the Lender, but at the cost and expense of the Borrower and without notice to the Borrower:

(a) request any Account Debtor obligated on any of the Accounts to make payments thereon directly to the Lender, with the Lender taking control of the Proceeds thereof;

(b) compromise, extend or renew any of the Collateral or deal with the same as it may deem advisable;

(c) make exchanges, substitutions or surrenders of all or any part of the Collateral;

(d) copy, transcribe, or remove from any place of business of the Borrower or any Subsidiary all books, records, ledger sheets, correspondence, invoices and documents, relating to or evidencing any of the Collateral or without cost or expense to the Lender, make such use of the Borrower’s or any Subsidiary’s place(s) of business as may be reasonably necessary to administer, control and collect the Collateral;

(e) demand, collect, receipt for and give renewals, extensions, discharges and releases of any of the Collateral;

(f) institute and prosecute legal and equitable proceedings to enforce collection of, or realize upon, any of the Collateral;

(g) settle, renew, extend, compromise, compound, exchange or adjust claims in respect of any of the Collateral or any legal proceedings brought in respect thereof;

(h) endorse or sign the name of the Borrower upon any Items of Payment, certificates of title, Instruments, Investment Property, stock powers, documents, documents of title, financing statements, assignments, notices or other writing relating to or part of the Collateral and on any proof of claim in bankruptcy against an Account Debtor;

(i) notify the Post Office authorities to change the address for the delivery of mail to the Borrower to such address or Post Office Box as the Lender may designate and receive and open all mail addressed to the Borrower; and

(j) take any other action necessary or beneficial to realize upon or dispose of the Collateral or to carry out the terms of this Agreement.

Any proceeds of sale or other disposition of the Collateral will be applied by the Lender to the payment first of any and all Enforcement Costs, and any balance of such proceeds will be applied to the Obligations in such order and manner as the Lender shall determine. If the sale or other disposition of the Collateral fails to fully satisfy the Obligations, the Borrower shall remain liable to the Lender for any deficiency.

Upon the occurrence and continuation of an Event of Default, the Lender without notice to or demand upon the Borrower and without waiving or releasing any of the Obligations or any Default or Event of Default, may (but shall be under no obligation to) at any time thereafter make such payment or perform such act for the account and at the expense of the Borrower, and may enter upon the premises of the Borrower for that purpose and take all such action thereon as the Lender may consider necessary or appropriate for such purpose and the Borrower hereby irrevocably appoints the Lender as its attorney-in-fact to do so, with power of substitution, in the name of the Lender or in the name of the Borrower or otherwise, for the use and benefit of the Lender, but at the cost and expense of the Borrower and without notice to the Borrower. All sums so paid or advanced by the Lender together with interest thereon from the date of payment, advance or incurring until paid in full at the Post-Default Rate and all costs and expenses, shall be deemed part of the Enforcement Costs, shall be paid by the Borrower to the Lender on demand, and shall constitute and become a part of the Obligations.

The Lender may from time to time proceed to protect or enforce its rights by an action or actions at law or in equity or by any other appropriate proceeding, whether for the specific performance of any of the covenants contained in this Agreement or in any of the other Financing Documents, or for an injunction against the violation of any of the terms of this Agreement or any of the other Financing Documents, or in aid of the exercise or execution of any right, remedy or power granted in this Agreement, the Financing Documents, and/or applicable Laws. The Lender is authorized to offset and apply to all or any part of the Obligations all moneys, credits and other property of any nature whatsoever of the Borrower now or at any time hereafter in the possession of, in transit to or from, under the control or custody of, or on deposit with, the Lender or any Affiliate of the Lender.

(e) By accepting payment after the due date of any amount payable under this Agreement or under any of the other Financing Documents, the Lender shall not be deemed to waive the right either to require prompt payment when due of all other amounts payable under this Agreement or under any of the other Financing Documents, or to declare a default for failure to effect such prompt payment of any such other amount.

The rights, powers and remedies provided in this Agreement and in the other Financing Documents are cumulative, may be exercised concurrently or separately, may be exercised from time to time and in such order as the Lender shall determine, subject to the provisions of this Agreement, and are in addition to, and not exclusive of, rights, powers and remedies provided by existing or future applicable Laws.

(b) the obligation to be fulfilled shall be reduced to the limit of such validity;

(c) if such provision or part thereof pertains to repayment of the Obligations, then, at the sole and absolute discretion of the Lender, all of the Obligations of the Borrower to the Lender shall become immediately due and payable; and

(d) if the affected provision or part thereof does not pertain to repayment of the Obligations, but operates or would prospectively operate to invalidate this Agreement in whole or in part, then such provision or part thereof only shall be void, and the remainder of this Agreement shall remain operative and in full force and effect.

The Lender may, without notice to or consent of the Borrower, assign to any Person (each an “Assignee” and collectively, the “Assignees”) all or a portion of the Lender’s Commitments. The Lender and its Assignee shall notify the Borrower in writing of the date on which the assignment is to be effective (the “Adjustment Date”). On or before the Adjustment Date, the Lender, the Borrower and the Assignee shall execute and deliver a written assignment agreement in a form acceptable to the Lender, which shall constitute an amendment to this Agreement to the extent necessary to reflect such assignment. Upon the request of the Lender following an assignment made in accordance with this Section 8.5, the Borrower shall issue new Notes to the Lender and its Assignee reflecting such assignment, in exchange for the existing Notes held by the Lender.

In addition, notwithstanding the foregoing, the Lender may at any time pledge all or any portion of the Lender’s rights under this Agreement, any of the Commitments or any of the Obligations to a Federal Reserve Bank.

The Lender may at any time sell to one or more financial institutions participating interests in any of the Lender’s Obligations or Commitments; provided, however, that (a) no such participation shall relieve the Lender from its obligations under this Agreement or under any of the other Financing Documents to which it is a party, (b) the Lender shall remain solely responsible for the performance of its obligations under this Agreement and under all of the other Financing Documents to which it is a party, and (c) the Borrower shall continue to deal solely and directly with the Lender in connection with the Lender’s rights and obligations under this Agreement and the other Financing Documents.

In connection with any sale, transfer, assignment or participation by the Lender in accordance with Section 8.5 (Assignments by Lender) or Section 8.6 (Participations by Lender), the Lender shall have the right to disclose to any actual or potential purchaser, assignee, transferee or participant all financial records, information, reports, financial statements and documents obtained in connection with this Agreement and/or any of the other Financing Documents or otherwise.

This Agreement and all other Financing Documents shall be binding upon and inure to the benefit of the Borrower and the Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lender.

All covenants, agreements, representations and warranties made by the Borrower in this Agreement, in any of the other Financing Documents, and in any certificate delivered pursuant hereto or thereto shall survive the making by the Lender of the Loans, the issuance of Letters of Credit and the execution and delivery of the Notes, shall be binding upon the Borrower regardless of how long before or after the date hereof any of the Obligations were or are incurred, and shall continue in full force and effect so long as any of the Obligations are outstanding and unpaid. From time to time upon the Lender’s request, and as a condition of the release of any one or more of the Security Documents, the Borrower and other Persons obligated with respect to the Obligations shall provide the Lender with such acknowledgments and agreements as the Lender may require to the effect that there exists no defenses, rights of setoff or recoupment, claims, counterclaims, actions or causes of action of any kind or nature whatsoever against the Lender and/or any of its agents and others, or to the extent there are, the same are waived and released.

The provisions of this Section shall survive the execution and delivery of this Agreement, the repayment of the other Obligations and shall survive the termination of this Agreement.

The Borrower acknowledges and agrees that the Financing Documents, including, this Agreement, shall be governed by the Laws of the State, as if each of the Financing Documents and this Agreement had each been executed, delivered, administered and performed solely within the State even though for the convenience and at the request of the Borrower, one or more of the Financing Documents may be executed elsewhere. The Lender acknowledges, however, that remedies under certain of the Financing Documents that relate to property outside the State may be subject to the laws of the state in which the property is located.

The Borrower irrevocably submits to the jurisdiction of any state or federal court sitting in the State over any suit, action or proceeding arising out of or relating to this Agreement or any of the other Financing Documents. The Borrower irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. Final judgment in any such suit, action or proceeding brought in any such court shall be conclusive and binding upon the Borrower and may be enforced in any court in which the Borrower is subject to jurisdiction, by a suit upon such judgment, provided that service of process is effected upon the Borrower in one of the manners specified in this Section or as otherwise permitted by applicable Laws.

The Borrower hereby irrevocably designates and appoints CT Corporation Systems, Inc., 4701 Cox Road, Suite 301, Glen Allen, Virginia 23060, as the Borrower’s authorized agent to receive on the Borrower’s behalf service of any and all process that may be served in any suit, action or proceeding of the nature referred to in this Section in any state or federal court sitting in the State. If such agent shall cease so to act, the Borrower shall irrevocably designate and appoint without delay another such agent in the State satisfactory to the Lender and shall promptly deliver to the Lender evidence in writing of such other agent’s acceptance of such appointment and its agreement that such appointment shall be irrevocable.

The Borrower hereby consents to process being served in any suit, action or proceeding of the nature referred to in this Section by (a) the mailing of a copy thereof by registered or certified mail, postage prepaid, return receipt requested, to the Borrower at the Borrower’s address designated in or pursuant to Section 8.1 (Notices), and (b) serving a copy thereof upon the agent, if any, designated and appointed by the Borrower as the Borrower’s agent for service of process by or pursuant to this Section. The Borrower irrevocably agrees that such service (y) shall be deemed in every respect effective service of process upon the Borrower in any such suit, action or proceeding, and (z) shall, to the fullest extent permitted by law, be taken and held to be valid personal service upon the Borrower. Nothing in this Section shall affect the right of the Lender to serve process in any manner otherwise permitted by law or limit the right of the Lender otherwise to bring proceedings against the Borrower in the courts of any jurisdiction or jurisdictions.

This Agreement may be executed in any number of duplicate originals or counterparts, each of such duplicate originals or counterparts shall be deemed to be an original and all taken together shall constitute but one and the same instrument.

The headings in this Agreement are included herein for convenience only, shall not constitute a part of this Agreement for any other purpose, and shall not be deemed to affect the meaning or construction of any of the provisions hereof.

Nothing herein contained shall be construed to constitute the Borrower as the agent of the Lender for any purpose whatsoever or to permit the Borrower to pledge any of the credit of the Lender. The Lender shall not be responsible or liable for any shortage, discrepancy, damage, loss or destruction of any part of the Collateral wherever the same may be located and regardless of the cause thereof. The Lender shall not, by anything herein or in any of the Financing Documents or otherwise, assume any of the Borrower’s obligations under any contract or agreement assigned to the Lender, and the Lender shall not be responsible in any way for the performance by the Borrower of any of the terms and conditions thereof.

Should the principal of or interest on the Notes become due and payable on other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day and in the case of principal, interest shall be payable thereon at the rate per annum specified in the Notes during such extension.

This Agreement and the Exhibits and Financing Documents referenced herein are intended by the Lender and the Borrower to be a complete, exclusive and final expression of the agreements contained herein. Neither the Lender nor the Borrower shall hereafter have any rights under any prior agreements pertaining to the matters addressed by this Agreement but shall look solely to this Agreement for definition and determination of all of their respective rights, liabilities and responsibilities under this Agreement.

THE BORROWER AND THE LENDER HEREBY JOINTLY AND SEVERALLY WAIVE TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO WHICH THE BORROWER AND THE LENDER MAY BE PARTIES, ARISING OUT OF OR IN ANY WAY PERTAINING TO (A) THIS AGREEMENT, (B) ANY OF THE FINANCING DOCUMENTS, OR (C) THE COLLATERAL. THIS WAIVER CONSTITUTES A WAIVER OF TRIAL BY JURY OF ALL CLAIMS AGAINST ALL PARTIES TO SUCH ACTIONS OR PROCEEDINGS, INCLUDING CLAIMS AGAINST PARTIES WHO ARE NOT PARTIES TO THIS AGREEMENT.

This waiver is knowingly, willingly and voluntarily made by the Borrower and the Lender, and the Borrower and the Lender hereby represent that no representations of fact or opinion have been made by any individual to induce this waiver of trial by jury or to in any way modify or nullify its effect.
