Explanation of Responses:

1. As previously reported, 15,607,882 shares of Common Stock of Digital Generation Systems, Inc. that have been beneficially owned by Mr. Ginsburg since January 18, 2001 have been subject to a pledge by Mr. Ginsburg to United Stated Media Corporation ("USMC") since they were acquired by Mr. Ginsburg. On December 12, 2003, Mr. Ginsburg and USMC agreed to amend the promissory note underlying the pledge, by extending the maturity date. As part of the amendment, 1,000,000 shares of the pledged Common Stock were released to Mr. Ginsburg, and the remaining 14,607,882 shares remain subject to the pledge. The price listed reflects the public trading price of Digital Generation Systems, Inc.'s Common Stock on the effective date of the amendment to Mr. Ginsburg's promissory note. Mr. Ginsburg's beneficial ownership of Common Stock of Digital Generation Systems, Inc. was not affected by this transaction.
