Bentley Board Approves Spin-off of Drug Delivery Business.

Bentley Sets July 22, 2008 as Date for Stockholders to Vote on Proposed Acquisition by Teva Pharmaceutical Industries Ltd.

EXETER, N.H. -- The board of directors of Bentley Pharmaceuticals, Inc. (NYSE: BNT) today approved the spin-off of its drug delivery business into a new publicly traded company to be called CPEX Pharmaceuticals, Inc. CPEX is a drug delivery company involved in the business of development, licensing and commercialization of pharmaceutical products utilizing validated drug delivery technology. The Bentley board also set the date for stockholders to vote on the proposed acquisition of Bentley by Teva Pharmaceutical Industries Ltd.

Spin-off of CPEX

As part of its approval, the Bentley board authorized a dividend on its common stock of one CPEX share for every 10 shares of Bentley common stock, and established the close of business on June 20, 2008 as the record date for stockholders entitled to receive the distribution of CPEX shares. The distribution is expected to take place after the close of business on June 30, 2008.

The dividend of CPEX common stock will be issued in book-entry form only, which means that no physical CPEX stock certificates will be issued. No fractional shares of CPEX common stock will be issued. Instead, fractional shares will be aggregated and sold on behalf of all affected stockholders of record, who then will receive the pro rata net cash value of such fractional shares. As a result of the spin-off, Bentley will no longer own any shares of CPEX common stock.

On the distribution date, Bentley, with the assistance of American Stock Transfer and Trust Company, the distribution agent, will electronically issue shares of CPEX common stock to stockholders of record or their broker, bank or other nominee on their behalf by way of direct registration in book-entry form. Bentley stockholders will not be required to make any payment, surrender or exchange their shares of Bentley common stock or take any other action to receive shares of CPEX common stock. For additional information, stockholders should contact American Stock Transfer and Trust Company by e-mail at [e-mail] or by phone at 800-937-5449.

The distribution will be more fully described in the information statement that, prior to the distribution date, will be mailed to stockholders of record on the record date.

Bentley expects a "when issued" public market for CPEX common stock to begin on or about June 18, 2008 on the NASDAQ Capital Market (NASDAQ) under the symbol "CPEXV." Following the spin-off, "regular way" trading of CPEX common stock is expected to start on July 1, 2008 under the ticker symbol "CPEX." Bentley's common stock will continue to trade on the New York Stock Exchange under the ticker symbol "BNT."

If Bentley stockholders sell shares of their Bentley common stock in the "regular way" market after the record date but prior to the distribution date, they may also be selling the right to receive shares of CPEX common stock in connection with those shares. Investors should consult with their financial advisors about selling their shares of Bentley common stock on or before the distribution date.

Special Meeting to Approve Merger

As previously announced on March 31, 2008, Bentley entered into a merger agreement with Teva Pharmaceutical Industries Ltd. (NASDAQ: TEVA), an Israeli corporation, and Beryllium Merger Corporation, a wholly owned, newly formed subsidiary of Teva. Pursuant to the terms of the merger agreement, Beryllium will merge with and into Bentley, and as a result, Bentley will become a wholly owned subsidiary of Teva. The board of Bentley set Tuesday, July 22, 2008, as the meeting date for stockholders to vote on this merger. The special stockholders meeting is scheduled to start at 10:00 a.m. ET at the Hilton Garden Inn, 100 High Street, Portsmouth, New Hampshire.

Bentley previously set the close of business on June 2, 2008, as the record date for determining stockholders who will be entitled to vote on the merger. The company plans to begin mailing the proxy statement on or about June 16, 2008 to all Bentley stockholders of record as of the record date.
