(the “Company”) entered into a first amendment (the “First Amendment”) to its Credit Agreement, dated as of August 2, 2010, among the Company, the lenders party thereto and Bank of America, N.A., as Administrative Agent (the “Credit Agreement”). The First Amendment to the Credit Agreement: (i) increases the revolving commitment amount by $50 million, to $150 million in the aggregate, and provides the Company the right to increase the aggregate commitment amount by an additional $25 million, to $175 million; (ii) extends the maturity date of the revolving credit facility from August 2, 2014 to August 2, 2015; (iii) decreases the ranges of applicable rates charged for interest on outstanding loans and letters of credit by 0.35%, from 2.50%-1.50% to 2.15%-1.15% for letter of credit fees and loans based on the Eurodollar rate and from 1.50%-0.50% to 1.15%-0.15% for loans based on the base rate; and (iv) permits the Company to incur certain securitization transactions of up to $50 million in the aggregate, so long as certain tests are met, including a maximum Consolidated Leverage Ratio test (as defined in the First Amendment) and a minimum Consolidated EBITDA test (as defined in the First Amendment). In the event the Company elects to incur securitization transactions in the future pursuant to (iv) above, (a) a new mandatory prepayment test will be implemented that will trigger prepayments based on the sum of the total outstanding borrowings under the revolving credit facility and any such securitization transaction measured against certain of the Company’s account receivables and (b) the quarterly maximum Consolidated Leverage Ratio test will be adjusted from 3.00:1.00 to 2.75:1.00.

The foregoing description of the First Amendment does not purport to be complete and is qualified in its entirety by reference to the First Amendment, which is attached hereto as Exhibit 10.1 and incorporated herein by reference.

(b) At the end of his term, on June 20, 2012, Peter J. Barris will retire as a director of the Company and will not stand for re-election at the 2012 Annual Meeting of Stockholders, which will take place on June 21, 2012.
