("Parent"), to purchase all outstanding shares of Class A Common Stock, par

(collectively, the "Shares"), of U.S. Franchise Systems, Inc., a Delaware

conditions of the Offer. Also enclosed herewith are certain other materials
related to the Offer, including the Company's Solicitation/Recommendation
Statement on Schedule 14D-9, as filed with the Securities and Exchange
Commission.

    WE ARE THE HOLDER OF RECORD OF SHARES HELD FOR YOUR ACCOUNT OR BENEFIT. A

    We request instructions as to whether you wish us to tender any or all of

Transmittal.

    Your attention is directed to the following:

        1.  The Offer price is $5.00 per Share net to the seller in cash,

    Properties, Inc., pursuant to which, as soon as practicable following the
    consummation of the Offer and the satisfaction or waiver of certain
    conditions, the Purchaser will be merged with and into the Company, with the
    Company surviving the merger as a majority owned subsidiary of Parent (the

    the Purchaser) will be converted into the right to receive $5.00 per Share
    in cash, without interest, as set forth in the Acquisition Agreement and

    Transmittal, stock transfer taxes on the purchase of Shares by the Purchaser
    pursuant to the Offer. However, backup withholding at a 31% rate may be
