(NASDAQ:SUPG), a pharmaceutical company dedicated to the discovery and development of novel cancer therapies, announced that stockholders have approved the issuance of shares to be issued in connection with the proposed acquisition of Astex Therapeutics Limited (“Astex”), a privately held, U.K.-based biotechnology company developing targeted therapies. The proposal to approve the share issuances in connection with the proposed acquisition of Astex passed by those voting either in person or by proxy at SuperGen’s annual meeting of stockholders on June 16, 2011. On June 13, 2011, the shareholders of Astex voted to approve the transaction.

“We are very pleased that voting stockholders voted more than 90% of their shares in favor of this transformational transaction,” said James S. J.

Pursuant to the terms of the agreement between the two companies, SuperGen will purchase all of the outstanding shares of Astex, paying Astex security holders $25 million in cash, plus shares in SuperGen common stock representing 35 percent of the total post closing shares outstanding. Subsequently, SuperGen will pay deferred consideration in the amount of $30 million in either stock or cash, at the discretion of the combined entity, over a period of 30 months. Additionally, SuperGen will assume all of the currently outstanding stock options of Astex.

The transaction is expected to close in July 2011, subject to satisfaction of customary closing conditions. After the close of the transaction, the combined entity, to be named Astex Pharmaceuticals, Inc., is expected to be listed on NASDAQ under the symbol ASTX.

If the transaction is completed, Astex Pharmaceuticals, Inc. will be headquartered in Dublin, California. Under the new management structure, James S.J. Manuso would serve as chairman and chief executive officer of Astex Pharmaceuticals, Inc.

Management expects that Astex Pharmaceuticals, Inc. will become recognized as a global leader in innovative oncology drug discovery, development and commercialization, with an estimated cash and cash equivalents position of more than $120 million post deal closure.
