Dollar Thrifty Automotive Group, Inc. announced that it amended its senior secured credit facility to extend the application of the current calculation of its leverage ratio test. Under the amended facility, compliance with the leverage ratio test at any date through Feb. 28, 2009 will be based on Corporate EBITDA for the trailing four quarters ended June 30, 2008, rather than for the most recently completed trailing four quarters.

The company also similarly amended fleet financing agreements with Chrysler Financial and another bank group.

In connection with the amendment of the senior secured credit facility, the company prepaid $10 million of its outstanding term loan and permanently reduced the aggregate outstanding enhancement letters of credit with respect to its commercial paper and medium-term note programs by $10 million.

Consistent with the prior amendment to this facility, during the amendment period, the company may not borrow under the revolving credit facility and must maintain at least $60 million of unrestricted cash and cash equivalents, among other restrictions. As of Sept. 30, 2008, the company had $209 million of unrestricted cash.

Pricing terms relating to borrowings under all of the amended agreements are unchanged.
