(b) the amount of all then outstanding and unpaid Obligations (but not including for this purpose the then outstanding principal amount of the Term Loan).

provided, however, that solely for the purposes of determining the Prime Rate Margin and the Eurodollar Rate Margin, to the extent the amount set forth in clause (a)(i) above exceeds the amount set forth in clause (a)(ii) above at any time, the Excess Availability as of such time shall be increased by up to Ten Million Dollars ($10,000,000) of the difference between those two (2) amounts.”

“1.43 ‘Maximum Credit’ shall mean, with reference to the Revolving Loans, the Term Loans and the Letter of Credit Accommodations, the amount of One Hundred Million Dollars ($100,000,000); provided, however, that so long as no Event of Default and no event or condition that, with notice or passage of time or both, would constitute an Event of Default, shall exist or have occurred and be continuing, Borrowers may, upon written request delivered to Agent from time to time, permanently increase the Maximum Credit, in increments of Five Million Dollars ($5,000,000) or an integral multiple of Five Million Dollars ($5,000,000), up to a total maximum amount not to exceed One Hundred Fifty Million Dollars ($150,000,000); and provided, further, that any increase of the

Maximum Credit to a total amount in excess of One Hundred Twenty Million ($120,000,000) shall be subject to the condition that an assignee or assignees shall have accepted an assignment by Wachovia Capital Finance Corporation (Western) or any successor Agent hereunder, in its capacity as a Revolving Loan Lender, of that portion of its Revolving Loan Commitment that is in excess of Seventy Million Dollars ($70,000,000) pursuant to Section 13.5 hereof.”

(c) Availability of Eurodollar Rate Loans. Clause (iv) of Section 3.1(b) of the Loan Agreement is hereby amended and restated to read in its entirety as follows:

“(iv)

(d) Unused Line Fee. Section 3.6 of the Loan Agreement is hereby amended and restated to read in its entirety as follows:

“3.6 Unused Line Fee. Borrowers shall pay to Agent, for the benefit of Lenders, monthly, an unused line fee equal to one-quarter of one percent (0.25%) per annum calculated upon the amount, if any, by which eighty percent (80%) of the Maximum Credit then in effect, exceeds the average daily principal balance of the outstanding Loans and Letter of Credit Accommodations during the immediately preceding month while this Agreement is in effect and for so long thereafter as any of the Obligations are outstanding, which fee shall be payable on the first day of each month in arrears.”

(e) Interim Financial Statements. The proviso in clause (i) of Section 9.6(a) of the Loan Agreement is hereby amended and restated to read in its entirety as follows:

“provided, that, if the average daily Excess Availability during any fiscal quarter (as determined on the dates on which Agent approves the weekly borrowing base certificates provided pursuant to clause (a) of Section 7.1 hereof) is not less than the greater of Ten Million Dollars ($10,000,000) or ten percent (10%) of the Maximum Credit then in effect, and so long as no Event of Default has occurred and is continuing, then during the immediately following fiscal quarter, such financial statements may be provided on a fiscal quarter basis on or before the earlier of the forty-fifth (45th) day after the end of such fiscal quarter or the date on which Borrowers file their Form 10Q with the Securities and Exchange Commission for such fiscal quarter.”

(f) Permitted Acquisitions. Clause (iii) of Section 9.10(d) of the Loan Agreement is hereby amended and restated to read in its entirety as follows:

“(iii) As of the date of the acquisition of the subject Target and any related Targets or the making of the subject Subsidiary Investments (as applicable) and after giving effect thereto, the Excess Availability would not be less than the greater of Ten Million Dollars ($10,000,000) or ten percent (10%) of the Maximum Credit then in effect;”

2. Wachovia Revolving Loan Commitment. Effective upon any increase in the Maximum Credit (pursuant to the proviso in the definition of “Maximum Credit” in Section 1.43 of the Loan Agreement as amended and restated above), the Revolving Loan Commitment of Wachovia Capital Finance Corporation (Western) or any successor Agent under the Loan Agreement, in its capacity as a Revolving Loan Lender (“Wachovia”) shall be increased by the amount of such increase in the Maximum Credit. In consideration of each such increase, Borrowers shall pay Wachovia (for its own account and not the account of any other Lender) a line increase fee equal to one-quarter of one percent (0.25%) of the amount of such increase, which fee shall be due and payable by Borrowers, and fully earned by Wachovia, on and as of the date of such increase. If the Maximum Credit and Wachovia’s Revolving Loan Commitment are increased as set forth above and Wachovia assigns a portion of its Revolving Loan Commitment to an assignee pursuant to Section 13.5 of the Loan Agreement, then to the extent and only to the extent required by such assignee as a condition to its acceptance of such assignment, Borrowers shall pay such assignee (for its own account and not the account of any other Lender) an acceptance fee which shall be due and payable by Borrowers, and fully earned by such assignee, on and as of the date of such acceptance; provided, however, that the aggregate sum of such acceptance fees shall not exceed one-eighth of one percent (0.125%) of the aggregate sum of the foregoing increases in the Maximum Credit and Wachovia’s Revolving Loan Commitment.
