Revolving Credit Facility Commitment. (a) Revolving Credit Loans. Subject to the terms and conditions and relying upon the representations and warranties set forth in this Note, the Bank agrees to make loans (the "Revolving Credit Loans") to the Makers at any time or from time to time on or after May 8, 2003 (the "Closing Date") and to and including the Business Day (as hereinafter defined) immediately preceding the Expiry Date (as hereinafter defined) in an aggregate principal amount which shall not exceed at any one time outstanding Five Million and 00/100 Dollars ($5,000,000.00) (the "Revolving Credit Facility Commitment"). Within the limits of time and amount set forth in this Section 1, and subject to the provisions of this Note including, without limitation, the Bank's right to demand repayment of the Revolving Credit Loans upon the occurrence of an Event of Default (as hereinafter defined), the Makers may borrow, repay and reborrow under this Section 1. (i) Making of Revolving Credit Loans. Subject to the terms and conditions set forth in this Note, and provided that the Makers have satisfied all applicable conditions specified herein, the Bank shall make Revolving Credit Loans to the Makers on such Business Day and in such amount as an Authorized Representative (as hereinafter defined) of the Makers shall request by written or telephonic notice (confirmed promptly, but in no event later than one Business Day thereafter, in writing) received by the Bank no later than 10:00 a.m. (Pittsburgh, Pennsylvania time) on the date of requested disbursement, which proceeds shall be available to the Makers at the Bank's Office (as hereinafter defined) in immediately available funds not later than 2:00 p.m. (Pittsburgh, Pennsylvania time) on such date. (b) Maximum Principal Balance of Revolving Credit Loans. The sum of the aggregate principal amount of all Revolving Credit Loans outstanding shall not exceed the amount of the Revolving Credit Facility Commitment. The Makers agree that if at any time the sum of the aggregate principal amount of all Revolving Credit Loans outstanding exceeds the amount of the Revolving Credit Facility Commitment (the "Excess Amount"), the Makers shall promptly, but in no event later than one Business Day thereafter, pay to the Bank such Excess Amount. If not sooner paid, the entire principal balance of all outstanding Revolving Credit Loans, together with all unpaid accrued interest thereon, and all other sums and costs owed to the Bank by the Makers pursuant to this Note, shall be immediately due and payable on the Expiry Date, without notice, presentment or demand of any kind. 2. Interest Rates. (a) Interest on the Revolving Credit Loans. Subject to the terms and conditions of this Note, the aggregate outstanding principal balance of the Revolving Credit Loans shall be bear interest for each day at a fluctuating rate per annum equal to the Prime Rate (as hereinafter defined). (b) Calculation of Interest and Fees; Adjustment to Prime Rate. Interest on the Revolving Credit Loans, unpaid fees and other sums payable hereunder shall be computed on the basis of a year of three hundred sixty (360) days and paid for the actual number of days elapsed. In the event of any change in the Prime Rate, the rate of interest on the Revolving Credit Loans shall be adjusted to immediately correspond with such change; provided, however, that any interest rate charged hereunder shall not exceed the Maximum Rate (as hereinafter defined). (c) Interest After Maturity or Default; Interest Laws. Upon the occurrence and during the continuance of an Event of Default, the unpaid principal amount of the Revolving Credit Loans or any portion thereof, accrued interest thereon, any fees or any other sums payable hereunder shall thereafter until paid in full bear interest at a rate per annum equal to the Prime Rate plus two percent (2.00%). Notwithstanding any provisions to the contrary contained in this Note, the Makers shall not be required to pay, and the Bank shall not be permitted to collect, any amount of interest in excess of the maximum amount of interest permitted by applicable Law (as hereinafter defined) ("Excess Interest"). If any Excess Interest is provided for or determined by a court of competent jurisdiction to have been provided for in this Note, then, in such event: (1) the provisions of this subsection shall govern and control; (2) the Makers shall not be obligated to pay any Excess Interest; (3) any Excess Interest that any Bank may have received hereunder shall be, at the Bank's option, (A) applied as a credit against the outstanding principal balance of the Indebtedness (as hereinafter defined) evidenced by this Note or accrued and unpaid interest thereon (not to exceed the maximum amount permitted by Law), (B) refunded to the payor thereof, or (C) any combination of the foregoing; (4) the interest rate(s) provided for herein shall be automatically reduced to the maximum lawful rate allowed from time to time under applicable Law (the "Maximum Rate"), and this Note shall be deemed to have been and shall be, reformed and modified to reflect such reduction; and (5) the Makers shall have no action against the Bank for any damages arising out of the payment or collection of any Excess Interest. 3. Description of Payments. (a) Interest Payments. The Makers shall pay to the Bank interest on the aggregate outstanding balance of the Revolving Credit Loans in arrears, on June 1, 2003 and on the first day of each calendar month thereafter through and including the Expiry Date. After maturity of any part of the Revolving Credit Loans (whether upon the occurrence of an Event of Default, by acceleration or otherwise), interest on such part of the Revolving Credit Loans shall -2- be immediately due and payable upon delivery by the Bank of an invoice for such interest without further notice, presentment, or demand of any kind. (b) Commitment Fee. The Makers shall pay to the Bank a commitment fee on the unused portion of the amount of the Revolving Credit Facility Commitment during the period from the date of this Note to the Expiry Date, payable in arrears on (i) July 1, 2003 (the "First Payment Date") and (ii) the Expiry Date (the "Second Payment Date"). The commitment fee payable on the First Payment Date shall be equal to the amount by which the amount of the Revolving Credit Facility Commitment has exceeded the average daily closing principal balance of the sum of the Revolving Credit Loans during the period beginning on the date of this Note and ending on June 30, 2003, multiplied by three-eighths of one percent (0.375%), multiplied by a fraction, the numerator of which is 54 and the denominator of which is 360. The commitment fee payable on the Second Payment Date shall be equal to the amount by which the amount of the Revolving Credit Facility Commitment has exceeded the average daily closing principal balance of the sum of the Revolving Credit Loans during the period beginning on July 1, 2003 and ending on the Expiry Date, multiplied by three-eighths of one percent (0.375%), multiplied by a fraction, the numerator of which is 39 and the denominator of which is 360. (c) Payments. All payments to be made with respect to principal, interest, fees or other amounts due from the Makers under this Note are payable at 12:00 noon (Pittsburgh, Pennsylvania time), on the day when due, without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived, and an action for the payments will accrue immediately. All such payments must be made to the Bank at its Office in U.S. Dollars and in funds immediately available at such Office, without setoff, counterclaim or other deduction of any nature. The Bank may in its discretion deduct such payments from the Makers' demand or deposit accounts with the Bank if the payments if not paid within five (5) days after the due date. All such payments shall be applied at the option of the Bank to accrued and unpaid interest, outstanding principal and other sums due under this Note in such order as the Bank, in its sole discretion, shall elect. All such payments shall be made absolutely net of, without deduction or offset, and altogether free and clear of any and all present and future taxes, levies, deductions, charges, and withholdings and all liabilities with respect thereto, excluding income and franchise taxes imposed on the Bank under the Laws of the United States or any state or political subdivision thereof. If the Makers are compelled by Law to deduct any such taxes or levies (other than such excluded taxes) or to make any such other deductions, charges, or withholdings (collectively, the "Required Deductions"), the Makers will pay to the Bank an additional amount equal to the sum of (i) the aggregate amount of all Required Deductions and (ii) the aggregate amount of United States federal or state income taxes required to be paid by the Bank in respect of such Required Deductions. (d) Additional Costs. (i) If, due to either (i) the introduction of, or any change in, or in the interpretation of, any Law or (ii) the compliance with any guideline or request from any central bank or other Official Body (whether or not having the force of Law), there shall be any increase in the cost to, or reduction in income receivable by, the Bank of making, funding or maintaining Revolving Credit Loans (or commitments to make the Revolving Credit Loans), then the Makers shall from time to time, upon demand by the Bank made within a reasonable -3- time after the Bank's determination thereof, pay to the Bank additional amounts sufficient to reimburse the Bank for any such additional costs or reduction in income. All such additional amounts shall be determined by the Bank in good faith using appropriate attribution and averaging methods ordinarily employed by the Bank. A certificate of the Bank submitted to the Makers in good faith as to the amount of such additional costs shall be conclusive and binding for all purposes, absent manifest error. (ii) If either (i) the introduction of, or any change in, or in the interpretation of, any Law or (ii) the compliance with any guideline or request from any central bank or other Official Body (whether or not having the force of Law), affects the amount of capital required to be maintained by the Bank or any corporation controlling the Bank and the Bank determines in good faith that the amount of such capital is increased by or based upon the existence of the Revolving Credit Loans (or commitment to make the Revolving Credit Loans), then, within ten (10) Business Days of demand by the Bank, the Makers shall pay to the Bank from time to time as specified by the Bank, additional amounts sufficient to compensate the Bank in the light of such circumstances, to the extent that the Bank determines in good faith such increase in capital to be allocable to the existence of the Bank's Revolving Credit Loans (or commitment to make the Revolving Credit Loans). Any such demand by the Bank must be made within a reasonable time. A certificate of the Bank in good faith submitted to the Makers as to such amounts shall be conclusive and binding for all purposes, absent manifest error. 4. Loan Account. The Bank will open and maintain on its books and records, including computer records, in accordance with its customary procedures, a loan account (the "Loan Account") for the Makers in which shall be recorded the date and amount of each Revolving Credit Loan made by the Bank and the date and amount of each payment and prepayment in respect thereof. The Bank shall record in the Loan Account the principal amount of the Revolving Credit Loans owing to the Bank from time to time. The Loan Account shall constitute presumptive evidence, absent manifest error, of the accuracy of the information contained therein. Any failure by the Bank to make any such notation or record shall not affect the obligations of the Makers to the Bank with respect to the Revolving Credit Loans. 5. Representations and Warranties. The Makers hereby acknowledge and agree that the representations and warranties set forth in Article III of the Loan Agreement shall be deemed to be set forth herein in their entirety, and the Makers hereby represent and warrant to the Bank that each such representation and warranty set forth in Article III of the Loan Agreement is true and correct on the Closing Date; provided, however, that the Makers hereby represent and warrant that the Makers will use the proceeds of the Revolving Credit Loans for general corporate and working capital purposes.

Each request by the Makers for any Revolving Credit Loan shall constitute a representation and warranty by the Makers that the conditions set forth in this Section 5 have been satisfied as of the date of such request. The failure of the Bank to receive notice from the Makers to the contrary before such Revolving Credit Loan is made shall constitute a further -4- representation and warranty by the Makers that the conditions referred to in this Section 5 have been satisfied as of the date such Revolving Credit Loan is made. 6. Affirmative Covenants. The Makers hereby acknowledge and agree that the affirmative covenants set forth in Article V of the Loan Agreement shall be deemed to be set forth herein in their entirety, and the Makers hereby covenant to the Bank that they shall comply with the terms and conditions of each such covenant set forth in Article V of the Loan Agreement. 7.
