During the Commitment Period the Company may use the Commitment by borrowing, prepaying the Loans in whole or in part and reborrowing, all in accordance with the terms and conditions hereof.

(b) Any Excess Line Commitment of the Bank shall be a part of the Bank’s Available Commitment to the extent that the Company has given notice to the Bank on or prior to the first day of any month that the Company requests that the Bank

make that portion of the Excess Line Commitment available, in increments of $500,000, to the Company during such month; provided, however, that at any time as there may exist any outstanding Loans under the Excess Line Commitment, the Company shall be deemed to have given notice requesting availability under the Excess Line Commitment.

(c) The Loans may be, to the extent any such Type is available in accordance with Schedule I hereto, either (i) LIBOR Loans, (ii) Prime Rate Loans, (iii) C/D Rate Loans (iv) Fed Funds Rate Loans, (v) Negotiated Rate Loans or (vi) a combination thereof, provided that no LIBOR Loan or C/D Rate Loan shall be made within the period commencing one month or 30 days, respectively, prior to the Commitment Termination Date but excluding such date.

(d) The Loans made by the Bank shall be evidenced by a promissory note of the Company, substantially in the form of Schedule II, with appropriate insertions, payable to the order of the Bank and representing the obligation of the Company to pay the aggregate unpaid principal amount of all Loans made by the Bank with interest thereon as prescribed in subsection 2.3.

The Bank is hereby authorized to record the date, Type and amount of each Loan made by the Bank, each continuation thereof, each conversion of all or a portion thereof to another Type, the date and amount of each prepayment of principal thereof, and, in the case of LIBOR Loans, C/D Rate Loans or Negotiated Rate Loans, the length of each Interest Period and the interest rate with respect thereto, on the schedule annexed to and constituting a part of its Note, and any such recordation shall constitute prima facie evidence of the accuracy of the information so recorded; provided, however, that the failure of the Bank to make any such recordation or any error in any such recordation shall not affect the obligations of the Company hereunder or under such Note; provided, further, however, that in the absence of any such recordation, the loan accounts and records of the Bank shall constitute prima facie evidence of the outstanding amount of any Loans and interest accrued thereon.

2.2 Termination or Reduction of Commitments; Extension of Commitment Termination Date. (a) The Company shall have the right, upon not less than three Business Days’ notice to the Bank, to terminate the Commitment or, from time to time, reduce the amount of the Commitment, provided that (i) no such reduction or termination shall be permitted if, after giving effect thereto and to any prepayments of the Loans made on the effective date thereof, the then outstanding principal amount of the Loans would exceed the amount of the Commitment then in effect and (ii) any termination of the Commitment while LIBOR Loans or C/D Rate Loans are outstanding and any reduction of the aggregate amount of the Commitment that reduces the amount of the Commitment below the principal amount of the LIBOR Loans or C/D Rate Loans then outstanding may be made only on the last day of the respective Interest Period for such LIBOR Loans or C/D Rate Loans. Termination of the Commitment shall also terminate the obligation of the Bank to make Loans.

(b) The Commitment once terminated or reduced may not be reinstated.

(c) The Company may deliver to the Bank not earlier than 45 and not later than 15 days prior to the Commitment Termination Date a written notice requesting that the Bank extend the Commitment Termination Date for an additional 364-day period.

Interest shall be computed on the outstanding principal amount on the basis of a 365-day or 366-day year, as applicable, and actual days elapsed. If at any time there is no interest rate option in effect for an amount outstanding hereunder, the Company shall be deemed to have elected the Prime Rate for such amount.

(b) C/D Rate Loans.

A C/D Rate Loan shall bear interest at the Adjusted C/D Rate plus the applicable Rating Level Margin set forth on Schedule I for each Interest Period. Interest shall be computed on the outstanding principal amount for the actual number of days elapsed from the first day of the applicable Interest Period to, but not including, the last day thereof, on the basis of a 360-day year.

A LIBOR Loan shall bear interest at the Adjusted LIBOR Rate plus the applicable Rating Level Margin for each Interest Period set forth on Schedule I .

Such request for a bid may be made by the Company at any time prior to the proposed Borrowing or conversion of outstanding Loans. Any Loan made at such bid rate shall be a Negotiated Rate Loan. The Bank shall advise Company of its bid rate and the Company may choose to accept such rate in its sole discretion by electing a Negotiated Rate Loan in its Notice of Election.

(c) On the date of a proposed Loan, the Bank shall transfer to the Company the principal amount of the Loan to such account in such bank as the Company instructs the Bank in writing. Loans shall be made and repaid in immediately available funds unless the Company and the Bank may otherwise agree in writing in their sole discretion.

2.5 Principal and Interest Payments; Prepayments.

All payments hereunder shall be applied first to interest, then to principal.

(d) Any overdue principal on any of the Loans, and to the extent permitted by law, overdue interest thereon, shall bear interest, payable on demand, for each day from the date on which payment was due until the date of payment at a rate per annum equal to the Prime Rate plus 1.5% per annum (computed on the basis of a 360-day year and the actual number of days elapsed).

2.6 Modification to Adjusted LIBOR Rate or Adjusted C/D Rate Calculations. If after the date of this Agreement there is a change in any law, rule or regulation, or in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency, or compliance by the Bank with any request or direction (whether or not having the force of law) of any such authority, central bank or comparable agency that subjects the Bank to additional costs in, or reduces, in the Bank’s opinion, the amount of any payment received or receivable by the Bank under this Agreement or under the Note by reason of obtaining funds in the LIBOR or domestic C/D markets, through imposition of additional taxes, reserves or any other conditions, then the formulas for calculating the Adjusted LIBOR Rate and Adjusted C/D Rate for LIBOR or C/D Rate Loans shall immediately be modified to reflect and include the impact of such change whether or not the Bank purchases funds in the applicable LIBOR or domestic C/D markets. The Bank shall provide the Company with a statement detailing any modification of calculation.

2.7 Unavailability of Certain Loans. If, with respect to any Interest Period for a C/D Rate Loan or LIBOR Loan, the Bank determines that deposits in dollars are not being offered in the relevant market for such Interest Period, or that

adequate and reasonable means do not exist for ascertaining the applicable rate for a LIBOR Loan or C/D Rate Loan, then the Bank shall promptly notify the Company thereof by telephone, confirmed in writing, and any request by the Company for such C/D Rate Loan or such LIBOR Loan shall be deemed to be rescinded. In the case of any outstanding C/D Rate Loans or LIBOR Loans so affected, on the last day of the then current Interest Period for such Loans, Borrower shall either repay the Loans in full or the Loans shall automatically be converted into Prime Rate Loans, or at the Company’s election, Loans of another available Type. Thereafter, the obligation of the Bank to make C/D Rate Loans or LIBOR Loans, as the case may be, shall be suspended until the Bank revokes the notice to the Company referenced in this subsection 2.7.

2.8 Changes in Law Rendering Certain Loans Illegal. If after the date of this Agreement there is a change in any law (including the adoption of any new law), rule or regulation or in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency that renders it illegal for the Bank to make or maintain C/D Rate Loans or LIBOR Loans, or makes it illegal for the Bank to fund itself in the applicable LIBOR or C/D markets, then the Bank shall promptly so notify the Company, and upon the effective date of such event, suspend availability of the LIBOR option or C/D Rate option for the duration of the illegality. If Bank requests, as may be required by the relevant law, rule, regulation, interpretation or administration, the Company shall repay or convert to another Type any such LIBOR Loan or C/D Rate Loan.

2.9 Capital Adequacy Adjustment. If, after the date hereof, the adoption or effectiveness of any applicable law, rule or regulation regarding capital adequacy, or any change in any existing law, rule or regulation or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Bank with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on the Bank’s capital or assets as a consequence of the Bank’s Commitment, Loans, credits or obligations under this Agreement to a level below that which the Bank could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration the Bank’s policies with respect to capital adequacy), and the Bank demonstrates that the amount of the reduction reasonably attributable to such adoption, effectiveness, change or compliance is material to the Bank, then from time to time, within fifteen (15) days after demand by the Bank, the Company shall (a) pay to the Bank such additional amount or amounts as will compensate the Bank for such reduction or (b) prepay the outstanding balance hereunder without premium or penalty except as required in subsection 2.11. In determining such amount(s), the Bank may use any reasonable averaging and attribution methods.

2.10 Commitment, Standby and Upfront Fees. During the term of this Agreement, the Company shall pay to the Bank commitment fees, standby fees and upfront fees computed at the rates set forth in Schedule I. The commitment fees and standby fees shall be computed for the actual number of days elapsed on the basis of a 360-day year, as applicable, and shall be due and payable quarterly in arrears on the

last day of March, June, September and December and on the Commitment Termination Date, unless payment terms are otherwise provided on Schedule I. The upfront fees shall be due and payable upon execution of this Agreement. Payment of fees shall be made at the office of Bank designated by Bank on Schedule I for the purpose of payment.

2.11 Indemnity. The Company agrees to indemnify the Bank and to hold the Bank harmless from any loss or expense which such Bank may sustain or incur as a consequence of (a) default by the Company in payment when due of the principal amount of or interest on any Loan, (b) default by the Company in making a borrowing or conversion after the Company has given a Notice of Election in accordance with subsection 2.4, and/or (c) the making by the Company of a payment of any LIBOR Loan or C/D Rate Loan on a day which is not the last day of the Interest Period pertaining thereto, including, without limitation, any such loss or expense arising from the reemployment of funds obtained by it to maintain its Loans hereunder or from fees payable to terminate the deposits from which such funds were obtained, but excluding loss of margin for the period after a prepayment described in clause (c) above and, as to clauses (a), (b) and (c) of this subsection 2.11, excluding any consequential damages. This covenant shall survive termination of this Agreement and payment of the Note.

2.12 Use of Proceeds. The proceeds of the Loans shall be used for general corporate purposes of the Company. The Company will not, nor will it permit any Subsidiary to, use any of the proceeds of the Loans to purchase or carry any “Margin Stock” (as defined in Regulation U of the Board of Governors of the Federal Reserve System, as amended from time to time).

3.4 Compliance with Laws. The operations of the Company and its Significant Subsidiaries are in compliance with all Requirements of Law, (a) except to the extent that the failure to comply therewith could not, in the aggregate, be reasonably expected to have a material adverse effect on the ability of the Company to perform its obligations under this Agreement or the Note or (b) except as disclosed in the Company’s periodic reports filed prior to the date of this Agreement with the Securities and Exchange Commission under the Securities Exchange Act of 1934.

3.11 Environmental. In the ordinary course of its business, the Borrower conducts an ongoing review of the effect of environmental laws on the business, operations, and properties of the Borrower, in the course of which it identifies and evaluates associated liabilities and costs (including, without limitation, any capital or operating expenditures required for clean-up or closure of properties presently or previously owned or operated, any capital or operating expenditures required to achieve or maintain compliance with environmental protection standards imposed by law or as a condition of any license, permit or contract, any related constraints on operating activities, including any periodic or permanent shutdown of any facility or reduction in the level of or change in the nature of operations conducted thereat and any actual or potential liabilities to third parties, including employees, and any related costs and expenses). On the basis of these reviews, the Borrower has reasonably concluded that environmental laws are unlikely to have a material adverse effect on the business, financial condition, results of operations, or prospects of the Borrower. The Company hereby represents and warrants that its business and assets and those of its subsidiaries are operated in compliance with applicable environmental laws and that no enforcement action in respect thereof is threatened or pending. The Company covenants to continue to so operate.
