EXHIBIT 99(a)(1)(11) FLIPSIDE, INC. ANNOUNCES SUCCESSFUL COMPLETION OF UPROAR TENDER OFFER BERKELEY, CA - MARCH 21, 2001 - Flipside, Inc. today announced the expiration of the subsequent offering period to the previously announced cash tender offer by a wholly owned subsidiary of Flipside to purchase all of the outstanding shares of common stock, par value $0.01 per share, of Uproar Inc. (Nasdaq: UPRO; EASDAQ: UPRO/UPROrs), at a price of $3.00 per share, net to the seller in cash, without interest thereon. The subsequent offering period to the tender offer expired, as scheduled, at 5:00 p.m. EST time on Wednesday, March 21, 2001. Based on information provided by the depositary for the tender offer, 42,637,377 shares of Uproar common stock were validly tendered, including guaranteed deliveries, representing approximately 92% of the outstanding shares of Uproar common stock. Pursuant to the terms of the offer, a wholly owned subsidiary of Flipside has accepted for payment, and will promptly pay for, all shares validly tendered in the offer. Flipside will acquire the remaining outstanding shares of Uproar common stock pursuant to a merger of its wholly owned subsidiary with and into Uproar. Flipside intends to send stockholders of Uproar who did not tender their shares in the tender offer instructions as to how to exchange their shares of Uproar stock for the $3.00 per share merger consideration. No further action is required by the remaining stockholders of Uproar to effect the merger. As a result of the merger, the remaining outstanding shares of Uproar common stock (except for shares held by Flipside or any of its subsidiaries, or by stockholders exercising dissenter's rights under Delaware law, if available) will be converted into the right to receive $3.00 in cash, without interest, and Uproar will thereby become a wholly owned subsidiary of Flipside.
