Set forth below is an excerpt of the transcript for the second quarter 2010 earnings conference call held by Avis Budget Group, Inc. on August 5, 2010.

Ron Nelson - Avis Budget Group, Inc. - Chairman and CEO

Thanks, Neal, and, good morning to all of you. Let me say a word about Dollar Thrifty, and then move on to the balance of the quarter. As you know, last week we submitted a bid to acquire Dollar Thrifty Automotive Group for $46.50 per share in cash and stock. We believe strongly that our bid constitutes a superior proposal to acquire the Company, and would note that Dollar Thrifty has not said otherwise. We want to reiterate our continued strong, but responsible interest in acquiring Dollar Thrifty, as it represents a substantial growth opportunity for our Company. Other than that, we don’t and won’t have anything else to say on this topic during today’s call, and would ask you to refrain from any questions or comments on the Dollar Thrifty situation during Q&A.
