The offers remain open and are each scheduled to expire at 12:00 midnight, New York City time, on August 31, 2005, unless extended or earlier terminated. If the Expiration Date of the offers is extended by more than three business days then the Total Consideration and the Tender Offer Consideration will be recalculated as of the tenth business day prior to such Expiration Date. The tender offers and the consent solicitations are being conducted in connection with Penn's pending acquisition of Argosy. The closing of the acquisition of Argosy remains subject to certain conditions, including the receipt of gaming approvals in Illinois. Penn's pending acquisition of Argosy is on the August 25 agenda for review by the Illinois Gaming Board. Though there can be no assurances on the outcomes of this meeting, if the Illinois regulatory approval is secured, Penn expects the acquisition of Argosy to close on September 1, 2005.

The obligation to accept for payment and to pay for notes and consents in each tender offer and consent solicitation is subject to customary conditions, including, among other things, the consummation of Penn's acquisition of Argosy, or TAC being satisfied in its sole discretion that such consummation will occur substantially concurrently with the expiration date of the tender offers, and TAC having received the proceeds of the financing on terms satisfactory to Penn, or being satisfied in its sole discretion that such financing and such proceeds will be received substantially concurrently with the expiration date of the tender offers.
