E. fifth, so long as no Event of Default has occurred and is continuing, to pay the principal of all Advances (exclusive of LIBOR Rate Loans prior to the end of the applicable Interest Period if, and only if, Lender charges Borrowers for a Funding Loss with respect to the prepayment of the LIBOR Rate Loan to which the payment is to be applied, except to the extent otherwise agreed by Administrative Borrower in writing) until paid in full,

F. sixth, if an Event of Default has occurred and is continuing, ratably (i) to pay the principal of all Advances until paid in full, (ii) to Lender, to be held by Lender as cash collateral in an amount up to 105% of the then extant Letter of Credit Usage until paid in full, and (iii) to Lender, to be held by Lender, for the benefit of the Bank Products Providers, as cash collateral in an amount up to the amount of the Bank Product Reserve established prior to the occurrence of, and not in contemplation of, the subject Event of Default, until Borrowers’ and their Domestic Subsidiaries’ obligations in respect of the then extant Bank Products have been paid in full or the cash collateral amount has been exhausted,

LOAN AND SECURITY AGREEMENT - Page 26

including interest accrued after the commencement of any Insolvency Proceeding), default interest, interest on interest, and expense reimbursements, whether or not any of the foregoing would be allowed or disallowed in whole or in part in any Insolvency Proceeding.

(iv) In the event of a direct conflict between the priority provisions of this Section 2.4 and other provisions contained in any other Loan Document, it is the intention of the parties hereto that such priority provisions in such documents shall be read together and construed, to the fullest extent possible, to be in concert with each other. In the event of any actual, irreconcilable conflict that cannot be resolved as aforesaid, the terms and provisions of this Section 2.4 shall control and govern.

2.5 Overadvances. If, at any time or for any reason, the amount of Obligations (other than Bank Product Obligations) owed by Borrowers to Lender pursuant to Section 2.1 or Section 2.12 is greater than either the Dollar or percentage limitations set forth in Section 2.1 or Section 2.12, as applicable (an “Overadvance”), Borrowers immediately shall pay to Lender, in cash, the amount of such excess, which amount shall be used by Lender to reduce the Obligations in accordance with the priorities set forth in Section 2.4(b). In addition, Borrowers hereby promise to pay the Obligations (including principal, interest, fees, costs, and expenses) in Dollars in full as and when due and payable under the terms of this Agreement and the other Loan Documents.

2.6 Interest Rates and Letter of Credit Fee: Rates, Payments, and Calculations.

(a) Interest Rates. Except as provided in clause (c) below, all Obligations (except for undrawn Letters of Credit and except for Bank Product Obligations) that have been charged to the Loan Account pursuant to the terms hereof shall bear interest on the Daily Balance thereof as follows: (i) if the relevant Obligation is an Advance that is a LIBOR Rate Loan, at a per annum rate equal to the LIBOR Rate plus the LIBOR Rate Margin, and (ii) otherwise, at a per annum rate equal to the Base Rate plus the Base Rate Margin.

(b) Letter of Credit Fee. Borrowers shall pay Lender monthly, in arrears, a Letter of Credit fee (in addition to the charges, commissions, fees, and costs set forth in Sections 2.12(d) and (e)) which shall accrue at a rate equal to three percent (2.50%) per annum times the original “face” or stated amount of all issued but undrawn Letters of Credit.

(i) all Obligations (except for undrawn Letters of Credit and except for Bank Product Obligations) that have been charged to the Loan Account pursuant to the terms hereof shall bear interest on the Daily Balance thereof at a per annum rate equal to two (2) percentage points above the per annum rate otherwise applicable hereunder, and

LOAN AND SECURITY AGREEMENT - Page 27

(ii) the Letter of Credit fee provided for above shall be increased to two (2) percentage points above the per annum rate otherwise applicable hereunder.

(d) Payment. Except as provided to the contrary in Section 2.13(a), interest and all fees payable hereunder (other than Letter of Credit fees) shall be due and payable, in arrears, on the first day of each month at any time that Obligations or obligation to extend credit hereunder are outstanding. Letter of Credit fees shall be due and payable, in advance, on the first day of each month at any time that Obligations or obligation to extend credit hereunder are outstanding. Borrowers hereby authorize Lender, from time to time, without prior notice to Borrowers, to charge such interest and fees, all Lender Expenses (as and when incurred), the charges, commissions, fees, and costs provided for in Section 2.12(d) (as and when accrued or incurred), the fees and costs provided for in Section 2.11 (as and when accrued or incurred), and all other payments as and when due and payable under any Loan Document (including any amounts due and payable to the Bank Product Providers in respect of Bank Products up to the amount of the then extant Bank Products Reserve) to Borrowers’ Loan Account, which amounts thereafter shall constitute Advances hereunder and shall accrue interest at the rate then applicable to Advances hereunder. Any interest not paid when due shall be compounded by being charged to Borrowers’ Loan Account and shall thereafter constitute Advances hereunder and shall accrue interest at the rate then applicable to Advances that are Base Rate Loans hereunder.

(e) Computation. All interest and fees chargeable under the Loan Documents shall be computed on the basis of a 360-day year for the actual number of days elapsed. In the event the Base Rate is changed from time to time hereafter, the rates of interest hereunder based upon the Base Rate automatically and immediately shall be increased or decreased by an amount equal to such change in the Base Rate.

(f) Intent to Limit Charges to Maximum Lawful Rate. In no event shall the interest rate or rates payable under this Agreement, plus any other amounts paid in connection herewith, exceed the highest rate permissible under any law that a court of competent jurisdiction shall, in a final determination, deem applicable. Borrowers and Lender, in executing and delivering this Agreement, intend legally to agree upon the rate or rates of interest and manner of payment stated within it; provided, however, that, anything contained herein to the contrary notwithstanding, if said rate or rates of interest or manner of payment exceeds the maximum allowable under applicable law, then, ipso facto, as of the date of this Agreement, Borrowers are and shall be liable only for the payment of such maximum as allowed by law, and payment received from or in respect of Borrowers in excess of such legal maximum, whenever received, shall be applied to reduce the principal balance of the Obligations to the extent of such excess.

2.7 Cash Management.

(a) Borrowers shall and shall cause each of their Domestic Subsidiaries to (i) establish and maintain cash management services of a type and on terms satisfactory to Lender at one or more of the banks set forth on Schedule 2.7(a) (each a “Cash Management Bank”), and shall request in writing and otherwise take such reasonable steps to direct that all of their and their Domestic Subsidiaries’ Account Debtors forward payment of the amounts owed by them

LOAN AND SECURITY AGREEMENT - Page 28

directly to such Cash Management Bank, and (ii) deposit or direct each applicable Cash Management Bank to deposit promptly, and in any event no later than the first Business Day after the date of receipt thereof, all of their Collections (including those sent directly by their Account Debtors to a Cash Management Bank) into a bank account in Lender’s name (a “Cash Management Account”) at one of the Cash Management Banks.

(b) Each Cash Management Bank shall establish and maintain Cash Management Agreements with Lender and Borrowers, in form and substance acceptable to Lender in the exercise of its Permitted Discretion. Each such Cash Management Agreement shall provide, among other things, that (i) all items of payment deposited in such Cash Management Account and proceeds thereof are held by such Cash Management Bank on behalf of Lender as bailee-in-possession for Lender, (ii) the Cash Management Bank has no rights of setoff or recoupment or any other claim against the applicable Cash Management Account, other than for payment of its service fees and other charges directly related to the administration of such Cash Management Account and for returned checks or other items of payment, and (iii) from and after the first Advance under the Revolving Credit Facility resulting from a request for a Borrowing for purposes other than payment of Lender Expenses that have been outstanding and unpaid for less than thirty (30) days, the Cash Management Bank will immediately forward by daily sweep all amounts in the applicable Cash Management Account to the Lender’s Account; the parties intending that requests for Borrowings solely to pay Lender Expenses, prior to other Advances under the Revolving Credit Facility, will not trigger the daily sweep of amounts in the Cash Management Accounts, unless the Lender Expenses have remained unpaid for thirty (30) days after the due date thereof.

(c) So long as no Default or Event of Default has occurred and is continuing, Administrative Borrower may amend Schedule 2.7(a) to add or replace a Cash Management Bank; provided, however, that (i) such prospective Cash Management Bank shall be satisfactory to Lender in the exercise of its Permitted Discretion and Lender shall have consented in writing (which consent will not, in the exercise of Lender’s Permitted Discretion, be withheld, delayed or conditioned) in advance to the opening of a Cash Management Account with the prospective Cash Management Bank, and (ii) prior to the time of the opening of such Cash Management Account, a Borrower or a Domestic Subsidiary of a Borrower, as applicable, and such prospective Cash Management Bank shall have executed and delivered to Lender a Cash Management Agreement. A Borrower or a Domestic Subsidiary of a Borrower, as applicable, shall close any of their Cash Management Accounts (and establish replacement cash management accounts in accordance with the foregoing sentence) promptly and in any event within 30 days of notice from Lender that the creditworthiness of any Cash Management Bank is no longer acceptable in Lender’s reasonable judgment, or as promptly as practicable and in any event within 60 days of notice from Lender that the operating performance, funds transfer, or availability procedures or performance of the Cash Management Bank with respect to Cash Management Accounts or Lender’s liability under any Cash Management Agreement with such Cash Management Bank is no longer acceptable in Lender’s reasonable judgment.

(d) The Cash Management Accounts shall be cash collateral accounts, with all cash, checks and similar items of payment in such accounts securing payment of the Obligations, and in which Borrowers hereby grant a Lien to Lender.

LOAN AND SECURITY AGREEMENT - Page 29

2.8 Crediting Payments. The receipt of any payment item by Lender (whether from transfers to Lender by the Cash Management Banks pursuant to the Cash Management Agreements or otherwise) shall not be considered a payment on account unless such payment item is a wire transfer of immediately available federal funds made to the Lender’s Account or unless and until such payment item is honored when presented for payment. Should any payment item not be honored when presented for payment, then Borrowers shall be deemed not to have made such payment and interest shall be calculated accordingly. Anything to the contrary contained herein notwithstanding, any payment item shall be deemed received by Lender only if it is received into the Lender’s Account on a Business Day on or before 2:00 p.m. (Georgia time). If any payment item is received into the Lender’s Account on a non-Business Day or after 2:00 p.m. (Georgia time) on a Business Day, it shall be deemed to have been received by Lender as of the opening of business on the immediately following Business Day.

2.9 Designated Account. Lender is authorized to make the Advances, and Lender is authorized to issue the Letters of Credit, under this Agreement based upon telephonic or other instructions received from anyone purporting to be an Authorized Person, or without instructions if pursuant to Section 2.6(d). Administrative Borrower agrees to establish and maintain the Designated Account with the Designated Account Bank for the purpose of receiving the proceeds of the Advances requested by Borrowers and made by Lender hereunder. Unless otherwise agreed by Lender and Administrative Borrower, any Advance requested by Borrowers and made by Lender hereunder shall be made to the Designated Account.

2.10 Maintenance of Loan Account; Statements of Obligations. Lender shall maintain an account on its books in the name of Borrowers (the “Loan Account”) on which Borrowers will be charged with all Advances made by Lender to Borrowers or for Borrowers’ account, the Letters of Credit issued by Lender for Borrowers’ account, and with all other payment Obligations hereunder or under the other Loan Documents (except for Bank Product Obligations), including, accrued interest, fees, and Lender Expenses. In accordance with Section 2.8, the Loan Account will be credited with all payments received by Lender from Borrowers or for Borrowers’ account, including all amounts received in the Lender’s Account from any Cash Management Bank. Lender shall, within 20 days after the close of each calendar month, render to Administrative Borrower statements regarding all activities in the Loan Account during such month, including principal, interest, fees, and including an itemization of all charges and expenses constituting Lender Expenses owing, and such statements, absent manifest error, shall be conclusively presumed to be correct and accurate and constitute an account stated between Borrowers and Lender unless, within 60 days after receipt thereof by Administrative Borrower, Administrative Borrower shall deliver to Lender written objection thereto describing the error or errors contained in any such statements.

2.11 Fees. Borrowers shall pay to Lender the following fees and charges, which fees and charges shall be non-refundable when paid (irrespective of whether this Agreement is terminated thereafter):

(a) Unused Line Fee. As an unused line fee (the “Unused Line Fee”), the Borrowers shall pay to Lender monthly, in arrears, for the previous month, on the first day of each calendar month following the Closing Date, and continuing during the remainder of the term of this Agreement, a fee equal to one-quarter of one percent (0.250%) per annum times the

LOAN AND SECURITY AGREEMENT - Page 30

result of (i) the Maximum Revolver Amount, minus (ii) the sum of (A) the average Daily Balance of Advances that were outstanding during the immediately preceding month, plus (B) the average Daily Balance of the Letter of Credit Usage during the immediately preceding month.

(b) Other Fees. Borrowers shall pay to Lender the fees set forth in the Fee Letter as and when due and payable pursuant to the terms of the Fee Letter.

2.12 Letters of Credit.

(a) Generally. Subject to the terms and conditions of this Agreement, Lender agrees to issue letters of credit for the account of Borrowers (each, an “L/C”) or to purchase participations or execute indemnities or reimbursement obligations (each such undertaking, an “L/C Undertaking”) with respect to letters of credit issued by an Underlying Issuer (as of the Closing Date, the prospective Underlying Issuer is to be Wells Fargo) for the account of Borrowers. To request the issuance of an L/C or an L/C Undertaking (or the amendment, renewal, or extension of an outstanding L/C or L/C Undertaking), Administrative Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by Lender) to Lender (reasonably in advance of the requested date of issuance, amendment, renewal, or extension) a notice requesting the issuance of an L/C or L/C Undertaking, or identifying the L/C or L/C Undertaking to be amended, renewed, or extended, the date of issuance, amendment, renewal, or extension, the date on which such L/C or L/C Undertaking is to expire, the amount of such L/C or L/C Undertaking, the name and address of the beneficiary thereof (or of the Underlying Letter of Credit, as applicable), and such other information as shall be necessary to prepare, amend, renew, or extend such L/C or L/C Undertaking. If requested by Lender, Borrowers also shall be an applicant under the application with respect to any Underlying Letter of Credit that is to be the subject of an L/C Undertaking. Lender shall have no obligation to issue a Letter of Credit if any of the following would result after giving effect to the requested Letter of Credit:

(i) the Letter of Credit Usage would exceed the Borrowing Base less the then extant amount of outstanding Advances, or

(ii) the Letter of Credit Usage would exceed Ten Million Dollars ($10,000,000), or

(iii) the Letter of Credit Usage would exceed the Maximum Revolver Amount less the then extant amount of outstanding Advances.

Borrowers and Lender acknowledge and agree that certain Underlying Letters of Credit may be issued to support letters of credit that already are outstanding as of the Closing Date. Each Letter of Credit (and corresponding Underlying Letter of Credit) shall be in form and substance acceptable to Lender (in the exercise of its Permitted Discretion), including the requirement that the amounts payable thereunder must be payable in Dollars. If Lender is obligated to advance funds under a Letter of Credit, Borrowers immediately shall reimburse such L/C Disbursement to Lender by paying to Lender an amount equal to such L/C Disbursement not later than 2:00 p.m., Georgia time, on the date that such L/C Disbursement is made, if

LOAN AND SECURITY AGREEMENT - Page 31

Administrative Borrower shall have received written or telephonic notice of such L/C Disbursement prior to 1:00 p.m., Georgia time, on such date, or, if such notice has not been received by Administrative Borrower prior to such time on such date, then not later than 2:00 p.m., Georgia time, on (i) the Business Day that Administrative Borrower receives such notice, if such notice is received prior to 1:00 p.m., Georgia time, on the date of receipt, and, in the absence of such reimbursement, the L/C Disbursement immediately and automatically shall be deemed to be an Advance hereunder and, thereafter, shall bear interest at the rate then applicable to Advances that are Base Rate Loans under Section 2.6. To the extent an L/C Disbursement is deemed to be an Advance hereunder, Borrowers’ obligation to reimburse such L/C Disbursement shall be discharged and replaced by the resulting Advance.

(b) Indemnification. Each Borrower hereby agrees to indemnify, save, defend, and hold Lender harmless from any loss, cost, expense, or liability, and reasonable attorneys fees incurred by Lender arising out of or in connection with any Letter of Credit; provided, however, that no Borrower shall be obligated hereunder to indemnify for any loss, cost, expense, liability, or related attorneys’ fees, to the extent that it is caused by the gross negligence or willful misconduct of Lender. Each Borrower agrees to be bound by the Underlying Issuer’s regulations and interpretations of any Underlying Letter of Credit or by Lender’s interpretations of any L/C issued by Lender to or for such Borrower’s account, even though this interpretation may be different from such Borrower’s own, and each Borrower understands and agrees that Lender shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following Borrowers’ instructions or those contained in the Letter of Credit or any modifications, amendments, or supplements thereto. Each Borrower understands that the L/C Undertakings may require Lender to indemnify the Underlying Issuer for certain costs or liabilities arising out of claims by Borrowers against such Underlying Issuer. Each Borrower hereby agrees to indemnify, save, defend, and hold Lender harmless with respect to any loss, cost, expense (including reasonable attorneys fees), or liability incurred by Lender under any L/C Undertaking as a result of Lender’s indemnification of any Underlying Issuer; provided, however, that no Borrower shall be obligated hereunder to indemnify for any loss, cost, expense, liability, or related attorneys’ fees, to the extent that it is caused by the gross negligence or willful misconduct of Lender.

(c) Authorization to Underlying Issuer. Each Borrower hereby authorizes and directs any Underlying Issuer to deliver to Lender all instruments, documents, and other writings and property received by such Underlying Issuer pursuant to such Underlying Letter of Credit and to accept and rely upon Lender’s instructions with respect to all matters arising in connection with such Underlying Letter of Credit and the related application.

(d) Charges, Fees, and Costs. Any and all charges, commissions, fees, and costs incurred by Lender relating to Underlying Letters of Credit shall be Lender Expenses for purposes of this Agreement and immediately shall be reimbursable by Borrowers to Lender for the account of Lender; it being acknowledged and agreed by each Borrower that, as of the Closing Date, the usage charge imposed by the prospective Underlying Issuer is 0.825% per annum times the face amount of each Underlying Letter of Credit, that such issuance charge may be changed from time to time, and that the Underlying Issuer also imposes a schedule of charges for amendments, extensions, drawings, and renewals.

LOAN AND SECURITY AGREEMENT - Page 32

(e) Changes in Law. If by reason of (i) any change after the Closing Date in any applicable law, treaty, rule, or regulation or any change in the interpretation or application thereof by any Governmental Authority, or (ii) compliance by the Underlying Issuer or Lender with any direction, request, or requirement (irrespective of whether having the force of law) of any Governmental Authority or monetary authority including, Regulation D of the Federal Reserve Board as from time to time in effect (and any successor thereto):

(i) any reserve, deposit, or similar requirement is or shall be imposed or modified in respect of any Letter of Credit issued hereunder, or

(ii) there shall be imposed on the Underlying Issuer or Lender any other condition regarding any Underlying Letter of Credit or any Letter of Credit issued pursuant hereto;

and the result of the foregoing is to increase, directly or indirectly, the cost to Lender of issuing, making, guaranteeing, or maintaining any Letter of Credit or to reduce the amount receivable in respect thereof by Lender, then, and in any such case, Lender may, at any time within a reasonable period after the additional cost is incurred or the amount received is reduced, notify Administrative Borrower, and Borrowers shall pay on demand such amounts as Lender may specify to be necessary to compensate Lender for such additional cost or reduced receipt, together with interest on such amount from the date of such demand until payment in full thereof at the rate then applicable to Base Rate Loans hereunder. The determination by Lender of any amount due pursuant to this Section, as set forth in a certificate setting forth the calculation thereof in reasonable detail (which certificate shall, if requested by Administrative Borrower, shall be delivered within thirty (30) days after such request), shall, in the absence of manifest or demonstrable error, be final and conclusive and binding on all of the parties hereto.

2.13 LIBOR Option.

(a) Interest and Interest Payment Dates. In lieu of having interest charged at the rate based upon the Base Rate, Borrowers shall have the option (the “LIBOR Option”) to have interest on all or a portion of the Advances be charged at a rate of interest based upon the LIBOR Rate. Interest on LIBOR Rate Loans shall be payable as follows: (i) on the last day of the Interest Period applicable thereto; (ii) upon the occurrence of an Event of Default in consequence of which Lender has elected to accelerate the maturity of all or any portion of the Obligations (provided, that Lender shall not accelerate any LIBOR Rate Loans unless all Base Rate Loans are or have been accelerated); or (iii) upon termination of this Agreement pursuant to the terms hereof. On the last day of each applicable Interest Period, unless Administrative Borrower properly has exercised the LIBOR Option with respect thereto, the interest rate applicable to such LIBOR Rate Loan automatically shall convert to the rate of interest then applicable to Base Rate Loans hereunder. At any time that an Event of Default has occurred and is continuing, Borrowers no longer shall have the option to request that Advances bear interest at the LIBOR Rate and Lender shall have the right to convert the interest rate on all outstanding LIBOR Rate Loans to the rate then applicable to Base Rate Loans hereunder.

(b) LIBOR Election.

(i) Administrative Borrower may, at any time and from time to time, so long as no Event of Default has occurred and is continuing, elect to exercise the LIBOR Option by notifying Lender prior to 2:00 p.m. (Georgia time) at least 3 Business Days prior to the commencement of the proposed Interest Period (the “LIBOR Deadline”). Notice of Administrative Borrower’s election of the LIBOR Option for a permitted portion of the Advances and an Interest Period pursuant to this Section shall be made by delivery to Lender of a LIBOR Notice received by Lender before the LIBOR Deadline, or by telephonic notice received by Lender before the LIBOR Deadline (to be confirmed by delivery to Lender of a LIBOR Notice received by Lender prior to 5:00 p.m. (Georgia time) on the same day).

(ii) Each LIBOR Notice shall be irrevocable and binding on Borrowers. In connection with each LIBOR Rate Loan, each Borrower shall indemnify, defend, and hold Lender harmless against any loss, cost, or expense incurred by Lender as a result of (a) the payment of any principal of any LIBOR Rate Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any LIBOR Rate Loan other than on the last day of the Interest Period applicable thereto, or (c) the failure to borrow, convert, continue or prepay any LIBOR Rate Loan on the date specified in any LIBOR Notice delivered pursuant hereto (such losses, costs, and expenses, collectively, “Funding Losses”). Funding Losses shall, with respect to Lender, be deemed to equal the amount determined by Lender to be the excess, if any, of (i) the amount of interest that would have accrued on the principal amount of such LIBOR Rate Loan had such event not occurred, at the LIBOR Rate that would have been applicable thereto, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period therefor), minus (ii) the amount of interest that would accrue on such principal amount for such period at the interest rate which Lender would be offered were it to be offered, at the commencement of such period, Dollar deposits of a comparable amount and period in the London interbank market. A certificate of Lender delivered to Administrative Borrower setting forth any amount or amounts that Lender is entitled to receive pursuant to this Section shall be conclusive absent manifest error.

(iii) Borrowers shall have not more than five (5) LIBOR Rate Loans in effect at any given time. Borrowers only may exercise the LIBOR Option for LIBOR Rate Loans of at least $1,000,000.00 and integral multiples of $500,000.00 in excess thereof.

(c) Prepayments. Borrowers may prepay LIBOR Rate Loans at any time; provided, however, that in the event that LIBOR Rate Loans are prepaid on any date that is not the last day of the Interest Period applicable thereto, including as a result of any automatic prepayment through any required application by Lender of proceeds of Borrowers’ and their Domestic Subsidiaries’ Collections in accordance with Section 2.4(b) or for any other reason

LOAN AND SECURITY AGREEMENT - Page 34

(other than as described in Section 2.13(d)(ii)(1)), including early termination of the term of this Agreement or acceleration of all or any portion of the Obligations pursuant to the terms hereof, each Borrower shall indemnify, defend, and hold Lender and its Participants harmless against any and all Funding Losses in accordance with clause (b) above.

(d) Special Provisions Applicable to LIBOR Rate.

(i) The LIBOR Rate may be adjusted by Lender on a prospective basis to take into account any additional or increased costs to Lender of maintaining or obtaining any eurodollar deposits or increased costs due to changes in applicable law occurring subsequent to the commencement of the then applicable Interest Period, including changes in tax laws (except changes of general applicability in corporate income tax laws) and changes in the reserve requirements imposed by the Board of Governors of the Federal Reserve System (or any successor), excluding the Reserve Percentage, which additional or increased costs would increase the cost of funding loans bearing interest at the LIBOR Rate. In any such event, Lender shall give Administrative Borrower notice of such a determination and adjustment and, upon its receipt of the notice from Lender, Administrative Borrower may, by notice to Lender (y) require Lender to furnish to Administrative Borrower a statement setting forth the basis for adjusting such LIBOR Rate and the method for determining the amount of such adjustment, or (z) repay the LIBOR Rate Loans with respect to which such adjustment is made (together with any amounts due under clause (b)(ii) above).

(ii) In the event that any change in market conditions or any law, regulation, treaty, or directive, or any change therein or in the interpretation of application thereof, shall at any time after the date hereof, in the reasonable opinion of Lender, make it unlawful or impractical for Lender to fund or maintain LIBOR Advances or to continue such funding or maintaining, or to determine or charge interest rates at the LIBOR Rate, Lender shall give notice of such changed circumstances to Administrative Borrower and (1) in the case of any LIBOR Rate Loans that are outstanding, the date specified in Lender’s notice shall be deemed to be the last day of the Interest Period of such LIBOR Rate Loans, and interest upon the LIBOR Rate Loans of Lender thereafter shall accrue interest at the rate then applicable to Base Rate Loans, and (2) Borrowers shall not be entitled to elect the LIBOR Option until Lender determines that it would no longer be unlawful or impractical to do so.

(e) No Requirement of Matched Funding. Anything to the contrary contained herein notwithstanding, neither Lender, nor any of its Participants, is required actually to acquire eurodollar deposits to fund or otherwise match fund any Obligation as to which interest accrues at the LIBOR Rate. The provisions of this Section shall apply as if Lender or its Participants had match funded any Obligation as to which interest is accruing at the LIBOR Rate by acquiring eurodollar deposits for each Interest Period in the amount of the LIBOR Rate Loans.

LOAN AND SECURITY AGREEMENT - Page 35

2.14 Capital Requirements. If, after the date hereof, Lender determines that (i) the adoption of or change in any law, rule, regulation or guideline regarding capital requirements for banks or bank holding companies, or any change in the interpretation or application thereof by any Governmental Authority charged with the administration thereof, or (ii) compliance by Lender or its parent bank holding company with any guideline, request or directive of any such entity regarding capital adequacy (whether or not having the force of law), has the effect of reducing the return on Lender’s or such holding company’s capital as a consequence of Lender’s obligations hereunder to a level below that which Lender or such holding company could have achieved but for such adoption, change, or compliance (taking into consideration Lender’s or such holding company’s then existing policies with respect to capital adequacy and assuming the full utilization of such entity’s capital) by any amount deemed by Lender to be material, then Lender may notify Administrative Borrower thereof. Following receipt of such notice, Borrowers agree to pay Lender on demand the amount of such reduction of return of capital as and when such reduction is determined, payable within 90 days after presentation by Lender of a statement of the amount and setting forth in reasonable detail Lender’s calculation thereof and the assumptions upon which such calculation was based (which statement shall be deemed true and correct absent manifest error). In determining such amount, Lender may use any reasonable averaging and attribution methods.

2.15 Joint and Several Liability of Borrowers.

(a) Each Borrower is accepting joint and several liability hereunder and under the other Loan Documents in consideration of the financial accommodations to be provided by Lender under this Agreement, for the mutual benefit, directly and indirectly, of each Borrower and in consideration of the undertakings of the other Borrowers to accept joint and several liability for the Obligations.

(b) Each Borrower, jointly and severally, hereby irrevocably and unconditionally accepts, not merely as a surety but also as a co-debtor, joint and several liability with the other Borrowers, with respect to the payment and performance of all of the Obligations (including, without limitation, any Obligations arising under this Section 2.15), it being the intention of the parties hereto that all the Obligations shall be the joint and several obligations of each Person composing Borrowers without preferences or distinction among them.

(c) If and to the extent that any of Borrowers shall fail to make any payment with respect to any of the Obligations as and when due or to perform any of the Obligations in accordance with the terms thereof, then in each such event the other Persons composing Borrowers will make such payment with respect to, or perform, such Obligation.

(d) The Obligations of each Person composing Borrowers under the provisions of this Section 2.15 constitute the absolute and unconditional, full recourse Obligations of each Person composing Borrowers enforceable against each such Borrower to the full extent of its properties and assets, irrespective of the validity, regularity or enforceability of this Agreement as against any other Borrower(s) or any other circumstances whatsoever.

(e) Except as otherwise expressly provided in this Agreement, each Person composing Borrowers hereby waives notice of acceptance of its joint and several liability, notice

LOAN AND SECURITY AGREEMENT - Page 36

of any Advances or Letters of Credit issued under or pursuant to this Agreement, notice of the occurrence of any Default, Event of Default, or of any demand for any payment under this Agreement, notice of any action at any time taken or omitted by Lender under or in respect of any of the Obligations, any requirement of diligence or to mitigate damages and, generally, to the extent permitted by applicable law, all demands, notices and other formalities of every kind in connection with this Agreement (except as otherwise provided in this Agreement). Each Person composing Borrowers hereby assents to, and waives notice of, any extension or postponement of the time for the payment of any of the Obligations, the acceptance of any payment of any of the Obligations, the acceptance of any partial payment thereon, any waiver, consent or other action or acquiescence by Lender at any time or times in respect of any default by any Person composing Borrowers in the performance or satisfaction of any term, covenant, condition or provision of this Agreement, any and all other indulgences whatsoever by Lender in respect of any of the Obligations, and the taking, addition, substitution or release, in whole or in part, at any time or times, of any security for any of the Obligations or the addition, substitution or release, in whole or in part, of any Person composing Borrowers. Without limiting the generality of the foregoing, each Borrower assents to any other action or delay in acting or failure to act on the part of Lender with respect to the failure by any Person composing Borrowers to comply with any of its respective Obligations, including, without limitation, any failure strictly or diligently to assert any right or to pursue any remedy or to comply fully with applicable laws or regulations thereunder, which might, but for the provisions of this Section 2.15, afford grounds for terminating, discharging or relieving any Person composing Borrowers, in whole or in part, from any of its Obligations under this Section 2.15, it being the intention of each Person composing Borrowers that, so long as any of the Obligations hereunder remain unsatisfied, the Obligations of such Person composing Borrowers under this Section 2.15 shall not be discharged except by performance and then only to the extent of such performance. The Obligations of each Person composing Borrowers under this Section 2.15 shall not be diminished or rendered unenforceable by any winding up, reorganization, arrangement, liquidation, reconstruction or similar proceeding with respect to any Person composing Borrowers or Lender. The joint and several liability of the Persons composing Borrowers hereunder shall continue in full force and effect notwithstanding any absorption, merger, amalgamation or any other change whatsoever in the name, constitution or place of formation of any of the Persons composing Borrowers or Lender.

(f) Each Person composing Borrowers represents and warrants to Lender that such Borrower is currently informed of the financial condition of Borrowers and of all other circumstances which a diligent inquiry would reveal and which bear upon the risk of nonpayment of the Obligations. Each Person composing Borrowers further represents and warrants to Lender that such Borrower has read and understands the terms and conditions of the Loan Documents. Each Person composing Borrowers hereby covenants that such Borrower will continue to keep informed of Borrowers’ financial condition, the financial condition of other guarantors, if any, and of all other circumstances which bear upon the risk of nonpayment or nonperformance of the Obligations.

(g) The provisions of this Section 2.15 are made for the benefit of Lender and its successors and Assignees, and may be enforced by it or them from time to time against any or all of the Persons composing Borrowers as often as occasion therefor may arise and without requirement on the part of Lender, successor, or assign first to marshal any of its or their claims or to exercise any of its or their rights against any of the other Persons composing Borrowers or

LOAN AND SECURITY AGREEMENT - Page 37

to exhaust any remedies available to it or them against any of the other Persons composing Borrowers or to resort to any other source or means of obtaining payment of any of the Obligations hereunder or to elect any other remedy. The provisions of this Section 2.15 shall remain in effect until all of the Obligations shall have been paid in full or otherwise fully satisfied. If at any time, any payment, or any part thereof, made in respect of any of the Obligations, is rescinded or must otherwise be restored or returned by Lender upon the insolvency, bankruptcy or reorganization of any of the Persons composing Borrowers, or otherwise, the provisions of this Section 2.15 will forthwith be reinstated in effect, as though such payment had not been made.

(h) Each of the Persons composing Borrowers hereby agrees that it will not enforce any of its rights of contribution or subrogation against the other Persons composing Borrowers with respect to any liability incurred by it hereunder or under any of the other Loan Documents, any payments made by it to Lender with respect to any of the Obligations or any collateral security therefor until such time as all of the Obligations have been paid in full in cash. Any claim which any Borrower may have against any other Borrower with respect to any payments to Lender hereunder or under any other Loan Documents are hereby expressly made subordinate and junior in right of payment, without limitation as to any increases in the Obligations arising hereunder or thereunder, to the prior payment in full in cash of the Obligations and, in the event of any insolvency, bankruptcy, receivership, liquidation, reorganization or other similar proceeding under the laws of any jurisdiction relating to any Borrower, its debts or its assets, whether voluntary or involuntary, all such Obligations shall be paid in full in cash before any payment or distribution of any character, whether in cash, securities or other property, shall be made to any other Borrower therefor.

(i) Each of the Persons composing Borrowers hereby agrees that, after the occurrence and during the continuance of any Event of Default, the payment of any amounts due with respect to the indebtedness owing by any Borrower to any other Borrower is hereby subordinated to the prior payment in full in cash of the Obligations. Each Borrower hereby agrees that after the occurrence and during the continuance of any Event of Default, such Borrower will not demand, sue for or otherwise attempt to collect any indebtedness of any other Borrower owing to such Borrower until the Obligations shall have been paid in full in cash. If, notwithstanding the foregoing sentence, such Borrower shall collect, enforce or receive any amounts in respect of such indebtedness, such amounts shall be collected, enforced and received by such Borrower as trustee for the Lender, and such Borrower shall deliver any such amounts to Lender for application to the Obligations in accordance with Section 2.4(b).

Lender in the exercise of its Permitted Discretion as sufficient to satisfy the reasonably estimated credit exposure) to be held by Lender for the benefit of the Bank Product Providers with respect to the then extant Bank Products Obligations), in full.

4.	CREATION OF SECURITY INTEREST

4.1 Grant of Security Interest. Each Borrower hereby grants to Lender for the benefit of Lender and the Bank Product Providers a continuing security interest in all of its right, title, and interest in all currently existing and hereafter acquired or arising Collateral, as security for the repayment of any and all of the Obligations in accordance with the terms and conditions of the Loan Documents and in order to secure prompt performance by Borrowers of each of their covenants and duties under the Loan Documents. Anything contained in this Agreement or any other Loan Document to the contrary notwithstanding, except for the use of cash in the ordinary course of business and for the purposes permitted under this Agreement, and except for Permitted Dispositions, Borrowers and their Domestic Subsidiaries have no authority, express or implied, to dispose of any item or portion of the Collateral.

4.2 Negotiable Collateral. In the event that any Borrower Collateral, including proceeds, is evidenced by or consists of Negotiable Collateral, and if and to the extent that Lender determines that perfection or priority of Lender’s security interest is dependent on or enhanced by possession, the applicable Borrower, immediately upon the request of Lender, shall endorse and deliver physical possession of such Negotiable Collateral to Lender.

4.3 Collection of Accounts, General Intangibles, and Negotiable Collateral. At any time after the occurrence and during the continuation of an Event of Default, Lender or Lender’s designee may (a) notify Account Debtors of Borrowers that Borrowers’ Accounts, chattel paper, or General Intangibles have been assigned to Lender or that Lender has a security interest therein, or (b) collect Borrowers’ Accounts, chattel paper, or General Intangibles directly and charge the reasonable collection costs and expenses to the Loan Account. Each Borrower agrees that it will hold in trust for Lender, as Lender’s trustee, any of its or its Domestic Subsidiaries’ Collections that it receives and immediately will deliver such Collections to Lender or a Cash Management Bank in their original form as received by such Borrower or its Domestic Subsidiaries.

4.4 Filing of Financing Statements; Commercial Tort Claims; Delivery of Additional Documentation Required. (a) Borrowers authorize Lender to file any financing statement necessary or, in the exercise of Lender’s Permitted Discretion, desirable to effectuate the transactions contemplated by the Loan Documents, and any continuation statement or

LOAN AND SECURITY AGREEMENT - Page 45

Borrowers also shall maintain public liability and product liability insurance, as well as insurance against larceny, embezzlement, and criminal misappropriation. All such policies of insurance shall be in such amounts and with such insurance companies as are reasonably satisfactory to Lender. Borrowers shall deliver copies of all such policies to Lender with a satisfactory lender’s loss payable endorsement (other than in respect of workers’ compensation insurance) naming Lender as loss payee (as its interests appear) or additional insured, as appropriate. Each policy of insurance or endorsement shall contain a clause requiring the insurer to give not less than 30 days prior written notice to Lender in the event of cancellation of the policy for any reason whatsoever.

(b) Administrative Borrower shall give Lender prompt notice of any loss covered by such insurance. Lender shall have the exclusive right to adjust any losses claimed under any such insurance policies in excess of $1,000,000 (or in any amount after the occurrence and during the continuation of an Event of Default), without any liability to Borrowers whatsoever in respect of such adjustments absent gross negligence or willful misconduct by Lender. Any monies received as payment for any loss under any insurance policy mentioned above (other than liability insurance policies) or as payment of any award or compensation for condemnation or taking by eminent domain, shall be paid over to Lender to be applied at the option of Lender either to the prepayment of the Obligations; provided, that in the case of proceeds of casualty insurance involving a casualty where the proceeds are in an amount less than $1,000,000 and so long as no Event of Default shall then be continuing, then such proceeds shall be disbursed to Administrative Borrower under staged payment terms reasonably satisfactory to Lender in the exercise of its Permitted Discretion for application to the cost of repairs, replacements, or restorations. Any such repairs, replacements, or restorations shall be effected with reasonable promptness and shall be of a value at least equal to the value of the items or property destroyed prior to such damage or destruction.

(c) Borrowers shall not, and shall not suffer or permit their Domestic Subsidiaries to, take out separate insurance concurrent in form or contributing in the event of loss with that required to be maintained under this Section 6.7, unless Lender is included thereon as named insured with the loss payable to Lender under a lender’s loss payable endorsement or its equivalent. Administrative Borrower immediately shall notify Lender whenever such separate insurance is taken out, specifying the insurer thereunder and full particulars as to the policies evidencing the same, and copies of such policies promptly shall be provided to Lender.

6.8 Location of Inventory and Equipment. Keep Borrowers’ and their Domestic Subsidiaries’ Inventory and Equipment only at the locations identified on Schedule 5.4 and their chief executive offices only at the locations identified on Schedule 5.6(b); provided, however,

LOAN AND SECURITY AGREEMENT - Page 58

that Administrative Borrower may amend Schedule 5.4 and Schedule 5.6(b) so long as such amendment occurs by written notice to Lender not less than 30 days prior to the date on which such Inventory or Equipment is moved to such new location or such chief executive office is relocated, so long as such new location is within the continental United States, and so long as, at the time of such written notification, the applicable Borrower provides to Lender a Collateral Access Agreement with respect thereto.

6.9 Compliance with Laws. Comply with the requirements of all applicable laws, rules, regulations, and orders of any Governmental Authority, including the Fair Labor Standards Act and the Americans With Disabilities Act, other than laws, rules, regulations, and orders the non-compliance with which, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Change.

6.10 Leases. Pay when due all rents and other amounts payable under any leases to that any Borrower or any Domestic Subsidiary of a Borrower is a party or by which any Borrower’s or any Domestic Subsidiary of a Borrower’s properties and assets are bound, unless such payments are the subject of a Permitted Protest or, in the case of any leases other than the Borrowers’ lease of the premises at 10811 S. Westview Circle, Houston, Texas (which premises are the storage site for the US Seismic Library), the loss or forfeiture of such lease would not cause a Material Adverse Change.

6.11 Existence. At all times preserve and keep in full force and effect each Borrower’s and each Domestic Subsidiary of a Borrower’s valid existence and good standing and any rights and franchises material to their businesses; provided, however, that nothing herein contained shall be deemed to prohibit or limit any Non-Material Domestic Subsidiary from liquidating, winding up or dissolving, or merging or consolidating with or into a Borrower or another Domestic Subsidiary.

6.12 Environmental.

(a) Keep any property either owned or operated by any Borrower or any Subsidiary of a Borrower free of any Environmental Liens or post bonds or other financial assurances sufficient to satisfy the obligations or liability evidenced by such Environmental Liens, (b) comply, in all material respects, with Environmental Laws and provide to Lender documentation of such compliance which Lender reasonably requests, (c) notify Lender, promptly upon obtaining knowledge thereof, of any release of a Hazardous Material of any reportable quantity from or onto property owned or operated by any Borrower or any Subsidiary of a Borrower and take any Remedial Actions required to abate said release or otherwise to come into compliance with applicable Environmental Law, and (d) promptly, but in any event within 5 days of its receipt thereof, provide Lender with written notice of any of the following: (i) notice that an Environmental Lien has been filed against any of the real or personal property of any Borrower or any Subsidiary of a Borrower, (ii) commencement of any Environmental Action or notice that an Environmental Action will be filed against any Borrower or any Subsidiary of a Borrower, and (iii) notice of a violation, citation, or other administrative order which reasonably could be expected to result in a Material Adverse Change.

6.13 Disclosure Updates. Promptly and in no event later than 5 Business Days after obtaining knowledge thereof, notify Lender if any written information, exhibit, or report furnished to Lender contained any untrue statement of a material fact or omitted to state any material fact necessary to make the statements contained therein not misleading in light of the circumstances in which made. The foregoing to the contrary notwithstanding, any notification pursuant to the foregoing provision will not cure or remedy the effect of the prior untrue statement of a material fact or omission of any material fact nor shall any such notification have the affect of amending or modifying this Agreement or any of the Schedules hereto.

6.14 Formation of Subsidiaries. At the time that any Borrower or any Guarantor forms any direct or indirect Domestic Subsidiary or acquires any direct or indirect Domestic Subsidiary after the Closing Date, such Borrower or such Guarantor shall (a) cause such new Domestic Subsidiary to provide to Lender a joinder to this Agreement or to the Guaranty and the Guarantor Security Agreement, together with such other security documents, as well as appropriate UCC-1 financing statements, all in form and substance satisfactory to Lender in the exercise of its Permitted Discretion (including being sufficient to grant Lender a first priority Lien (subject to Permitted Liens) in and to the assets of such newly formed or acquired Domestic Subsidiary), (b) provide to Lender a pledge agreement and appropriate certificates and powers or UCC-1 financing statements, hypothecating all of the direct or beneficial ownership interest owned by the subject Borrower or Guarantor in such new Domestic Subsidiary, in form and substance satisfactory to Lender in the exercise of its Permitted Discretion, and (c) provide to Lender all other documentation, including one or more opinions of counsel satisfactory to Lender in the exercise of its Permitted Discretion, which in its Permitted Discretion is appropriate with respect to the execution and delivery of the applicable documentation referred to above. Any document, agreement, or instrument executed or issued pursuant to this Section 6.14 shall be a Loan Document.

6.15 Mergers and Transfers of Assets. In the event that any Domestic Subsidiary merges into another Domestic Subsidiary or Borrower or sells, assigns, or conveys assets to another Domestic Subsidiary or Borrower, Borrowers will (i) give Lender telephonic or written notice at least one week but not more than one month prior to any such merger, sale, assignment or conveyance, (ii) will promptly thereafter deliver to Lender such amendments to and reaffirmations of the Loan Documents, each in form and substance satisfactory to Lender, that Lender may request in connection therewith, and (iii) cause to filed, if necessary, appropriate amendments to financing statements on Form UCC-3 in such office or offices and to take such other actions as may be necessary or, in the Permitted Discretion of Lender, desirable to continue the perfection the Lender’s Liens in the Collateral.

(b) If a notice of Lien is filed of record either (i) with respect to any Borrower’s or any Material Domestic Subsidiary’s assets, or (ii) with respect to the assets of any one or more Non-Material Domestic Subsidiaries that owns assets (exclusive of intercompany balances) in excess of $250,000.00 (measured on the basis of book value or fair market value, whichever is greater, on an aggregate, cumulative basis for all such Non-Material Domestic Subsidiaries, from the Closing Date through any date of measurement), by any state, county, municipal, or governmental agency that is not a Non-Federal Priority Lien (a “Non-Federal Non-Priority Lien”); provided, however, that, if the aggregate amount claimed with respect to any such Non-Federal Non-Priority Liens, or combination thereof, is less than $500,000, an Event of Default shall not occur under this subsection if the claims that are the subject of such Liens are the subject of Permitted Protests and if the Liens are released, discharged, or bonded against within 30 days of each such Lien first being filed of record or, if earlier, at least 5 days prior to the date on which assets that are subject to such Liens are subject to being sold or forfeited and, in any such case, Lender shall have the absolute right to establish and maintain a reserve against the Borrowing Base and the Maximum Revolver Amount in an amount equal to the aggregate amount of the underlying claims (determined by Lender, in its Permitted Discretion, and irrespective of any Permitted Protests with respect thereto and including any penalties or interest that are estimated by Lender, in its Permitted Discretion, to arise in connection therewith);

8.8 If one or more judgments or other claims involving an aggregate amount of $250,000 or more, in excess of the amount covered by insurance, becomes a Lien or encumbrance upon any material portion of the assets of any Borrower, any Material Domestic Subsidiary, or any Non-Material Domestic Subsidiary with intercompany receivables in excess

LOAN AND SECURITY AGREEMENT - Page 69

of $250,000, and the same is not released, discharged, bonded against, or stayed pending appeal before the earlier of 30 days after the date it first arises or 5 days prior to the date on which such asset is subject to being forfeited by such Borrower, Material Domestic Subsidiary, or Non-Material Domestic Subsidiary;

8.9(a) If there is a default in one or more agreements to which Borrower is a party with one or more third Persons relative to Borrower’s Indebtedness involving an aggregate amount of $250,000, or more, and such default (i) occurs at the final maturity of obligations thereunder, or (ii) results in a right by such third Person(s), irrespective of whether exercised, to accelerate the maturity of Borrower’s obligations thereunder, or (b) if there is a default in any other material agreement to which Borrower is a party with one or more third Persons and such default results in a right by such third Person(s), irrespective of whether exercised, to terminate such agreement;

8.10 If any Borrower, any Material Domestic Subsidiary, or one or more Non-Material Domestic Subsidiaries that owns assets (exclusive of intercompany balances) in excess of $250,000.00 (measured on the basis of book value or fair market value, whichever is greater, on an aggregate, cumulative basis for all such Non-Material Domestic Subsidiaries, from the Closing Date through any date of measurement) makes any payment on account of Indebtedness that has been contractually subordinated in right of payment to the payment of the Obligations, except to the extent such payment is permitted by the terms of the subordination provisions applicable to such Indebtedness;

8.11 If any material misstatement or misrepresentation exists now or hereafter in any warranty, representation, statement, or Record made to Lender by any Borrower, any Subsidiary of a Borrower, or any officer, employee, agent, or director of any Borrower or any Subsidiary of a Borrower;

8.12 If the obligation of any Guarantor under the Guaranty is limited or terminated by operation of law or by such Guarantor thereunder, other than as expressly permitted pursuant to Section 7.3 above;

8.13 If this Agreement or any other Loan Document that purports to create a Lien, shall, for any reason (other than Lender’s acts or omissions), fail or cease to create a valid and perfected and, except to the extent permitted by the terms hereof or thereof, first priority Lien on or security interest in the Collateral covered hereby or thereby;

8.14 Any provision of any Loan Document shall at any time for any reason be declared to be null and void by a court of competent jurisdiction, or the validity or enforceability thereof shall be contested by any Borrower or any Domestic Subsidiary of a Borrower, or a proceeding shall be commenced by any Borrower or any Domestic Subsidiary of a Borrower, or by any Governmental Authority having jurisdiction over any Borrower or any Domestic Subsidiary of a Borrower, seeking to establish the invalidity or unenforceability thereof, or any Borrower or any Domestic Subsidiary of a Borrower shall deny that it has any liability or obligation purported to be created under any Loan Document;

LOAN AND SECURITY AGREEMENT - Page 70

9.	THE LENDER’S RIGHTS AND REMEDIES.

9.1 Rights and Remedies. Upon the occurrence, and during the continuation, of an Event of Default, Lender (at its election but without notice of its election and without demand) may do any one or more of the following, all of which are authorized by Borrowers:

(a) Declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or otherwise, immediately due and payable;

(b) Cease advancing money or extending credit to or for the benefit of Borrowers under this Agreement, under any of the Loan Documents, or under any other agreement between Borrowers and Lender;

(c) Terminate this Agreement and any of the other Loan Documents as to any future liability or obligation of Lender, but without affecting any of the Lender’s Liens in the Collateral and without affecting the Obligations;

(d) Settle or adjust disputes and claims directly with Borrowers’ Account Debtors for amounts and upon terms which Lender considers advisable in the exercise of its Permitted Discretion, and in such cases, Lender will credit the Loan Account with only the net amounts received by Lender in payment of such disputed Accounts after deducting all Lender Expenses incurred or expended in connection therewith;

(e) Cause Borrowers to hold all of their returned Inventory in trust for Lender, and segregate all such Inventory from all other assets of Borrowers or in Borrowers’ possession;

(f) Without notice to or demand upon any Borrower, make such payments and do such acts as Lender considers necessary or reasonable in its Permitted Discretion to protect its security interests in the Collateral. Each Borrower agrees to assemble the Collateral if Lender so requires, and to make the Collateral available to Lender at a place that Lender may designate which is reasonably convenient to both parties. Each Borrower authorizes Lender to enter the premises where the Collateral is located, to take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any Lien that in Lender’s Permitted Discretion appears to conflict with the Lender’s Liens in and to the Collateral and to pay all reasonable expenses incurred in connection therewith and to charge Borrowers’ Loan Account therefor. With respect to any of Borrowers’ owned or leased premises, each Borrower hereby grants Lender a license to enter into possession of such premises and to occupy the same, without charge, in order to exercise any of Lender’s rights or remedies provided herein, at law, in equity, or otherwise;

LOAN AND SECURITY AGREEMENT - Page 71

(g) Without notice to any Borrower (such notice being expressly waived), and without constituting an acceptance of any collateral in full or partial satisfaction of an obligation (within the meaning of the Code), set off and apply to the Obligations any and all (i) balances and deposits of any Borrower held by Lender (including any amounts received in the Cash Management Accounts), or (ii) Indebtedness at any time owing to or for the credit or the account of any Borrower held by Lender;

(h) Hold, as cash collateral, any and all balances and deposits of any Borrower held by Lender, and any amounts received in the Cash Management Accounts, to secure the full and final repayment of all of the Obligations;

(i) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein) the Borrower Collateral. Each Borrower hereby grants to Lender a license or other right to use, without charge, such Borrower’s labels, patents, copyrights, trade secrets, trade names, trademarks, service marks, and advertising matter, or any property of a similar nature, as it pertains to the Borrower Collateral, in completing production of, advertising for sale, and selling any Borrower Collateral and such Borrower’s rights under all licenses and all franchise agreements shall inure to Lender’s benefit;

(j) Sell the Borrower Collateral at either a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including Borrowers’ premises) as Lender, in the exercise of its Permitted Discretion, determines is commercially reasonable. It is not necessary that the Borrower Collateral be present at any such sale;

(k) Lender shall give notice of the disposition of the Borrower Collateral as follows:

(i) Lender shall give Administrative Borrower (for the benefit of the applicable Borrower) a notice in writing of the time and place of public sale, or, if the sale is a private sale or if some other disposition other than a public sale is to be made of the Borrower Collateral, the time on or after which the private sale or other disposition is to be made; and

(ii) The notice shall be personally delivered or mailed, postage prepaid, to Administrative Borrower as provided in Section 12, at least 10 days before the earliest time of disposition set forth in the notice; no notice needs to be given prior to the disposition of any portion of the Borrower Collateral that is perishable or threatens to decline speedily in value or that is of a type customarily sold on a recognized market;

(l) Lender may credit bid and purchase at any public sale;

(m) Lender may seek the appointment of a receiver or keeper to take possession of all or any portion of the Borrower Collateral or to operate same and, to the maximum extent permitted by law, may seek the appointment of such a receiver without the requirement of prior notice or a hearing; and

LOAN AND SECURITY AGREEMENT - Page 72

(n) Lender shall have all other rights and remedies available to it at law or in equity pursuant to any other Loan Documents.

9.2 Remedies Cumulative. The rights and remedies of Lender under this Agreement, the other Loan Documents, and all other agreements shall be cumulative. Lender shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Lender of one right or remedy shall be deemed an election, and no waiver by Lender of any Event of Default shall be deemed a continuing waiver. No delay by Lender shall constitute a waiver, election, or acquiescence by it.

10.

TAXES AND EXPENSES.

If any Borrower fails to pay any monies (whether taxes, assessments, insurance premiums, or, in the case of leased properties or assets, rents or other amounts payable under such leases) due to third Persons, or fails to make any deposits or furnish any required proof of payment or deposit, all if, as, and to the extent required under the terms of this Agreement, then, Lender, in its sole discretion and without prior notice to any Borrower, may do any or all of the following: (a) make payment of the same or any part thereof, (b) set up such reserves in Borrowers’ Loan Account as Lender deems necessary to protect Lender from the exposure created by such failure, or (c) in the case of the failure to comply with Section 6.7 hereof, obtain and maintain insurance policies of the type described in Section 6.7 and take any action with respect to such policies as Lender deems prudent in the exercise of its Permitted Discretion. Any such amounts paid by Lender shall constitute Lender Expenses and any such payments shall not constitute an agreement by Lender to make similar payments in the future or a waiver by Lender of any Event of Default under this Agreement. Lender need not inquire as to, or contest the validity of, any such expense, tax, or Lien and the receipt of the usual official notice for the payment thereof shall be conclusive evidence that the same was validly due and owing.

11.

WAIVERS; INDEMNIFICATION.

11.1 Demand; Protest. Each Borrower waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment, nonpayment at maturity, release, compromise, settlement, extension, or renewal of documents, instruments, chattel paper, and guarantees at any time held by Lender on which any such Borrower may in any way be liable.

11.2 Lender’s Liability for Collateral. Each Borrower hereby agrees that: (a) so long as Lender complies with its obligations, if any, under the Code, Lender shall not in any way or manner be liable or responsible for: (i) the safekeeping of the Borrower Collateral, (ii) any loss or damage thereto occurring or arising in any manner or fashion from any cause, (iii) any diminution in the value thereof, or (iv) any act or default of any carrier, warehouseman, bailee, forwarding agency, or other Person (provided that, if such Person has been chosen by Lender, such choice was made in Lender’s Permitted Discretion), and (b) all risk of loss, damage, or destruction of the Borrower Collateral shall be borne by Borrowers.

11.3 Indemnification. Each Borrower shall indemnify, defend, and hold the Lender-Related Persons and each Participant (each, an “Indemnified Person”) harmless (to the fullest

LOAN AND SECURITY AGREEMENT - Page 73

extent permitted by law) from and against any and all claims, demands, suits, actions, investigations, proceedings, and damages, and all reasonable attorneys fees and disbursements and other costs and expenses actually incurred in connection therewith (as and when they are incurred and irrespective of whether suit is brought), at any time asserted against, imposed upon, or incurred by any of them (a) in connection with or as a result of or related to the execution, delivery, enforcement, performance, or administration (including any restructuring or workout with respect hereto) of this Agreement, any of the other Loan Documents, or the transactions contemplated hereby or thereby or the monitoring of Borrowers’ and their Domestic Subsidiaries’ compliance with the terms of the Loan Documents, and (b) with respect to any investigation, litigation, or proceeding related to this Agreement, any other Loan Document, or the use of the proceeds of the credit provided hereunder (irrespective of whether any Indemnified Person is a party thereto), or any act, omission, event, or circumstance in any manner related thereto (all the foregoing, collectively, the “Indemnified Liabilities”). The foregoing to the contrary notwithstanding, Borrowers shall have no obligation to any Indemnified Person under this Section 11.3 with respect to any Indemnified Liability that a court of competent jurisdiction finally determines to have resulted from the gross negligence or willful misconduct of such Indemnified Person or that is based on any theory of liability for special, indirect, consequential or punitive damages (as opposed to direct or actual damages). This provision shall survive the termination of this Agreement and the repayment of the Obligations. If any Indemnified Person makes any payment to any other Indemnified Person with respect to an Indemnified Liability as to which Borrowers were required to indemnify the Indemnified Person receiving such payment, the Indemnified Person making such payment is entitled to be indemnified and reimbursed by Borrowers with respect thereto. WITHOUT LIMITATION, THE FOREGOING INDEMNITY SHALL APPLY TO EACH INDEMNIFIED PERSON WITH RESPECT TO INDEMNIFIED LIABILITIES WHICH IN WHOLE OR IN PART ARE CAUSED BY OR ARISE OUT OF ANY NEGLIGENT ACT OR OMISSION OF SUCH INDEMNIFIED PERSON OR OF ANY OTHER PERSON.

12. NOTICES. Unless otherwise provided in this Agreement, all notices or demands by Borrowers or Lender to the other relating to this Agreement or any other Loan Document shall be in writing and (except for financial statements and other informational documents which may be sent by first-class mail, postage prepaid) shall be personally delivered or sent by registered or certified mail (postage prepaid, return receipt requested), overnight courier, electronic mail (at such email addresses as Administrative Borrower or Lender, as applicable, may designate to each other in accordance herewith), or telefacsimile to Borrowers in care of Administrative Borrower or to Lender, as the case may be, at its address set forth below:

14.

ASSIGNMENTS AND PARTICIPATIONS; SUCCESSORS.

14.1 Assignments and Participations

(a) Lender may assign and delegate to one or more assignees (each an “Assignee”) that are Eligible Transferees all, or any ratable part of all, of the Obligations and the other rights and obligations of Lender hereunder and under the other Loan Documents; provided, however, that Borrowers may continue to deal solely and directly with Lender in connection with the interest so assigned to an Assignee until (i) written notice of such assignment, together with payment instructions, addresses, and related information with respect to the Assignee, have been given to Administrative Borrower by Lender and the Assignee and (ii) Lender and its Assignee have delivered to Borrower an appropriate assignment and acceptance agreement. Anything contained herein to the contrary notwithstanding, the Assignee need not be an Eligible Transferee if such assignment is in connection with any merger, consolidation, sale, transfer, or other disposition of all or any substantial portion of the business or loan portfolio of Lender.

(b) From and after the date that Lender provides Administrative Borrower with such written notice and executed assignment and acceptance agreement, (i) the Assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such assignment and acceptance agreement, shall have the rights and obligations of Lender under the Loan Documents, and (ii) Lender shall, to the extent that rights and obligations hereunder and under the other Loan Documents have been assigned by it pursuant to such assignment and acceptance agreement, relinquish its rights (except with respect to Section 11.3 hereof) and be released from any future obligations under this Agreement (and in the case of an assignment and acceptance covering all or the remaining portion of Lender’s rights and obligations under this Agreement and the other Loan Documents, Lender shall cease to be a

LOAN AND SECURITY AGREEMENT - Page 76

party hereto and thereto), and such assignment shall effect a novation between Borrowers and the Assignee; provided, however, that nothing contained herein shall release Lender from obligations that survive the termination of this Agreement, including Lender’s obligations under Section 16.8 of this Agreement.

(c) Immediately upon Borrower’s receipt of such fully executed assignment and acceptance agreement, this Agreement shall be deemed to be amended to the extent, but only to the extent, necessary to reflect the addition of the Assignee and the resulting adjustment of the rights and duties of Lender arising therefrom.

(d) Lender may at any time sell to one or more commercial banks, financial institutions, or other Persons not Affiliates of Lender (a “Participant”) participating interests in Obligations and the other rights and interests of Lender hereunder and under the other Loan Documents; provided, however, that (i) Lender shall remain the “Lender” for all purposes of this Agreement and the other Loan Documents and the Participant receiving the participating interest in the Obligations and the other rights and interests of Lender hereunder shall not constitute a “Lender” hereunder or under the other Loan Documents and Lender’s obligations under this Agreement shall remain unchanged, (ii) Lender shall remain solely responsible for the performance of such obligations, (iii) Borrowers and Lender shall continue to deal solely and directly with each other in connection with Lender’s rights and obligations under this Agreement and the other Loan Documents, (iv) Lender shall not transfer or grant any participating interest under which the Participant has the right to approve any amendment to, or any consent or waiver with respect to, this Agreement or any other Loan Document, except to the extent such amendment to, or consent or waiver with respect to this Agreement or of any other Loan Document would (A) extend the final maturity date of the Obligations hereunder in which such Participant is participating, (B) reduce the interest rate applicable to the Obligations hereunder in which such Participant is participating, (C) release all or substantially all of the Collateral or guaranties (except to the extent expressly provided herein or in any of the Loan Documents) supporting the Obligations hereunder in which such Participant is participating, (D) postpone the payment of, or reduce the amount of, the interest or fees payable to such Participant through Lender, or (E) change the amount or due dates of scheduled principal repayments or prepayments or premiums, and (v) all amounts payable by Borrowers hereunder shall be determined as if Lender had not sold such participation, except that, if amounts outstanding under this Agreement are due and unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall be deemed to have the right of set-off in respect of its participating interest in amounts owing under this Agreement to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement. The rights of any Participant shall only be derivative through Lender and no Participant shall have any rights under this Agreement or the other Loan Documents or any direct rights as to Borrowers or Guarantors, the Collections of Borrowers or their Domestic Subsidiaries, the Collateral, or otherwise in respect of the Obligations. No Participant shall have the right to participate directly in the making of decisions by Lender.

(e) In connection with any such assignment or participation or proposed assignment or participation, Lender may, subject to the provisions of Section 16.8, disclose all documents and information which it now or hereafter may have relating to Borrowers and their Subsidiaries and their respective businesses.

LOAN AND SECURITY AGREEMENT - Page 77

(f) Any other provision in this Agreement notwithstanding, Lender may at any time create a security interest in, or pledge, all or any portion of its rights under and interest in this Agreement in favor of any Federal Reserve Bank in accordance with Regulation A of the Federal Reserve Bank or U.S. Treasury Regulation 31 CFR §203.24, and such Federal Reserve Bank may enforce such pledge or security interest in any manner permitted under applicable law.

14.2 Successors. This Agreement shall bind and inure to the benefit of the respective successors and Assignees of each of the parties; provided, however, that Borrowers may not assign this Agreement or any rights or duties hereunder without Lender’s prior written consent and any prohibited assignment shall be absolutely void ab initio. No consent to assignment by Lender shall release any Borrower from its Obligations. Lender may assign this Agreement and the other Loan Documents and its rights and duties hereunder and thereunder pursuant to Section 14.1 hereof and, except as expressly required pursuant to Section 14.1 hereof, no consent or approval by any Borrower is required in connection with any such assignment.

15.

AMENDMENTS; WAIVERS.

15.1 Amendments and Waivers. No amendment or waiver of any provision of this Agreement or any other Loan Document, and no consent with respect to any departure by Borrowers therefrom, shall be effective unless the same shall be in writing and signed by Lender and Administrative Borrower (on behalf of all Borrowers) and then any such waiver or consent shall be effective only in the specific instance and, if a specific purpose is set forth in such waiver or consent, for the specific purpose for which it was given.

15.2 No Waivers; Cumulative Remedies. No failure by any party to exercise any right, remedy, or option under this Agreement or any other Loan Document, or delay in exercising the same, will operate as a waiver thereof. No waiver by any party will be effective unless it is in writing, and then only to the extent specifically stated. No waiver on any occasion shall affect or diminish any party’s rights thereafter to require strict performance on any subsequent occasion of any provision of this Agreement. The parties’ rights under this Agreement and the other Loan Documents will be cumulative and not exclusive of any other right or remedy that the parties may have.

16.

GENERAL PROVISIONS.

16.1 Effectiveness. This Agreement shall be binding and deemed effective when executed by Borrowers and Lender.

16.2 Section Headings. Section headings and numbers have been set forth herein for convenience only. Unless the contrary is compelled by the context, everything contained in each Section applies equally to this entire Agreement.

16.3 Interpretation. Neither this Agreement nor any uncertainty or ambiguity herein shall be construed against Lender or Borrowers, whether under any rule of construction or otherwise. On the contrary, this Agreement has been reviewed by all parties and shall be construed and interpreted according to the ordinary meaning of the words used so as to accomplish fairly the purposes and intentions of all parties hereto.

LOAN AND SECURITY AGREEMENT - Page 78

16.4 Severability of Provisions. Each provision of this Agreement shall be severable from every other provision of this Agreement for the purpose of determining the legal enforceability of any specific provision.

16.5 Withholding Taxes. All payments made by Borrowers hereunder or under any note will be made without setoff, counterclaim, or other defense, except as required by applicable law other than for Taxes (as defined below). All such payments will be made free and clear of, and without deduction or withholding for, any present or future taxes, levies, imposts, duties, fees, assessments or other charges of whatever nature now or hereafter imposed by any jurisdiction (other than the United States) or by any political subdivision or taxing authority thereof or therein (other than of the United States) with respect to such payments (but excluding, any tax imposed by any jurisdiction or by any political subdivision or taxing authority thereof or therein (i) measured by or based on the net income or net profits of Lender, or (ii) to the extent that such tax results from a change in the circumstances of Lender, including a change in the residence, place of organization, or principal place of business of Lender, or a change in the branch or lending office of Lender participating in the transactions set forth herein) and all interest, penalties or similar liabilities with respect thereto (all such non-excluded taxes, levies, imposts, duties, fees, assessments or other charges being referred to collectively as “Taxes”). If any Taxes are so levied or imposed, each Borrower agrees to pay the full amount of such Taxes, and such additional amounts as may be necessary so that every payment of all amounts due under this Agreement or under any note, including any amount paid pursuant to this Section 16.5 after withholding or deduction for or on account of any Taxes, will not be less than the amount provided for herein; provided, however, that Borrowers shall not be required to increase any such amounts payable to Lender if the increase in such amount payable results from Lender’s own willful misconduct or gross negligence. Borrowers will furnish to Lender as promptly as possible after the date the payment of any Taxes is due pursuant to applicable law certified copies of tax receipts evidencing such payment by Borrowers.

16.6 Counterparts; Telefacsimile Execution. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Agreement. Delivery of an executed counterpart of this Agreement by telefacsimile shall be equally as effective as delivery of an original executed counterpart of this Agreement. Any party delivering an executed counterpart of this Agreement by telefacsimile also shall deliver an original executed counterpart of this Agreement but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Agreement. The foregoing shall apply to each other Loan Document mutatis mutandis.

16.7 Revival and Reinstatement of Obligations. If the incurrence or payment of the Obligations by any Borrower or Guarantor or the transfer to Lender of any property in respect of the Obligations shall for any reason subsequently be declared to be void or voidable under any state or federal law relating to creditors’ rights, including provisions of the Bankruptcy Code relating to fraudulent conveyances, preferences, or other voidable or recoverable payments of money or transfers of property (collectively, a “Voidable Transfer”), and if Lender is required to repay or restore, in whole or in part, any such Voidable Transfer, or elects to do so upon the reasonable advice of its counsel, then, as to any such Voidable Transfer, or the amount thereof

LOAN AND SECURITY AGREEMENT - Page 79

that Lender is required or elects to repay or restore, and as to all reasonable costs, expenses, and attorneys fees of Lender related thereto, the liability of Borrowers or Guarantor automatically shall be revived, reinstated, and restored and shall exist as though such Voidable Transfer had never been made.

16.8 Confidentiality. Lender agrees that material, non-public information regarding Borrowers and their Subsidiaries and other Affiliates, their operations, assets, and existing and contemplated business plans shall be treated by Lender in a confidential manner, and shall not be disclosed by Lender to Persons who are not parties to this Agreement, except: (a) to attorneys for and other advisors, accountants, auditors, and consultants to Lender, (b) to Subsidiaries and Affiliates of Lender (including the Bank Product Providers), provided that any such Subsidiary or Affiliate shall have agreed to receive such information hereunder subject to the terms of this Section 16.8, (c) as may be required by statute, decision, or judicial or administrative order, rule, or regulation, (d) as may be agreed to in advance by Administrative Borrower or as requested or required by any Governmental Authority pursuant to any subpoena or other legal process, (e) as to any such information that is or becomes generally available to the public (other than as a result of prohibited disclosure by Lender or any of its Subsidiaries or Affiliates), (f) in connection with any assignment, prospective assignment, sale, prospective sale, participation or prospective participations, or pledge or prospective pledge of Lender’s interest under this Agreement, provided that any such assignee, prospective assignee, purchaser, prospective purchaser, participant, prospective participant, pledgee, or prospective pledgee shall have agreed in writing to receive such information hereunder subject to the terms of this Section 16.8, and (g) in connection with any litigation or other adversary proceeding involving parties hereto which such litigation or adversary proceeding involves claims related to the rights or duties of such parties under this Agreement or the other Loan Documents. The provisions of this Section 16.8 shall survive for 2 years after the payment in full of the Obligations. Anything contained herein or in any other Loan Document to the contrary notwithstanding, the obligations of confidentiality contained herein and therein, as they relate to the transactions contemplated hereby, shall not apply to the federal tax structure or federal tax treatment of such transactions, and each party hereto (and any employee, representative, or agent of any party hereto) may disclose to any and all Persons, without limitation of any kind, the federal tax structure and federal tax treatment of such transactions (including all written materials related to such tax structure and tax treatment). The preceding sentence is intended to cause the transactions contemplated hereby to not be treated as having been offered under conditions of confidentiality for purposes of Section 1.6011-4(b)(3) (or any successor provision) of the Treasury Regulations promulgated under Section 6011 of the IRC, and shall be construed in a manner consistent with such purpose. In addition, each party hereto acknowledges that it has no proprietary or exclusive rights to the tax structure of the transactions contemplated hereby or any tax matter or tax idea related thereto.

16.9 Integration. This Agreement, together with the other Loan Documents, reflects the entire understanding of the parties with respect to the transactions contemplated hereby and shall not be contradicted or qualified by any other agreement, oral or written, before the date hereof.

16.10 USA PATRIOT Act. Agent hereby notifies Borrowers that pursuant to the requirements of the USA PATRIOT Act, Title III of Pub. L. 107-56, signed into law October 26, 2001 (“Patriot Act”), it is required to obtain, verify and record information that identifies each of the Loan Parties, which information includes the names and addresses of Loan Parties and other information that will allow Agent to identify the Loan Parties in accordance with the Patriot Act.

16.11 Parent as Agent for Borrowers. Each Borrower hereby irrevocably appoints Parent as the borrowing agent and attorney-in-fact for all Borrowers (the “Administrative Borrower”) which appointment shall remain in full force and effect unless and until Lender shall have received prior written notice signed by each Borrower that such appointment has been revoked and that another Borrower has been appointed Administrative Borrower. Each Borrower hereby irrevocably appoints and authorizes the Administrative Borrower (i) to provide Lender with all notices with respect to Advances and Letters of Credit obtained for the benefit of any Borrower and all other notices and instructions under this Agreement and (ii) to take such action as the Administrative Borrower deems appropriate on its behalf to obtain Advances and Letters of Credit and to exercise such other powers as are reasonably incidental thereto to carry out the purposes of this Agreement. It is understood that the handling of the Loan Account and Collateral of Borrowers in a combined fashion, as more fully set forth herein, is done solely as an accommodation to Borrowers in order to utilize the collective borrowing powers of Borrowers in the most efficient and economical manner and at their request, and that Lender shall not incur liability to any Borrower as a result hereof. Each Borrower expects to derive benefit, directly or indirectly, from the handling of the Loan Account and the Collateral in a combined fashion since the successful operation of each Borrower is dependent on the continued successful performance of the integrated group. To induce Lender to do so, and in consideration thereof, each Borrower hereby jointly and severally agrees to indemnify Lender harmless against any and all liability, expense, loss or claim of damage or injury, made against Lender by any Borrower or by any third party whosoever, arising from or incurred by reason of (a) the handling of the Loan Account and Collateral of Borrowers as herein provided, (b) Lender’s relying on any instructions of the Administrative Borrower, or (c) any other action taken by Lender hereunder or under the other Loan Documents, except that Borrowers will have no liability to any Lender-Related Person under this Section 16.10 with respect to any liability that has been finally determined by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Lender-Related Person.

16.12 Amendment and Restatement. Each Borrower acknowledges and agrees that (a) this Agreement amends, restates and replaces, but does not extinguish the indebtedness evidenced by, Prior Loan Agreement in its entirety, and (b) unless otherwise amended, restated or replaced, each of the Loan Documents executed in connection with the Prior Loan Agreement continues in full force and effect with each reference therein to the Prior Loan Agreement being changed to refer to this Agreement as the same may be further amended, modified, supplemented and restated from time to time.
