Companies, Inc. today announced that its Par Pharmaceutical, Inc. operating
subsidiary has entered into an exclusive acquisition and license agreement
with Handa Pharmaceuticals, LLC to acquire Handa's Abbreviated New Drug
Application (ANDA) for quetiapine fumarate extended-release tablets, the
generic version of AstraZeneca's Seroquel XR^®. Handa believes it is the
first applicant to file an ANDA containing a paragraph IV certification for
the 50 mg, 150 mg, 200 mg and 300 mg strengths of the product, which would

approximately $808 million. The ANDA also includes a 400 mg dosage strength.

Under the terms of the agreement, Par has made a payment for the ANDA and for
exclusive rights to market, sell and distribute quetiapine fumarate
extended-release tablets in the U.S. under the ANDA, subject to its final
approval by the U.S. Food and Drug Administration. Par will receive a share
of profits from the sales of the product. Under the terms of a prior
settlement agreement with AstraZeneca, which has been assigned to Par, Par has
a license to enter the U.S. market with quetiapine fumarate extended-release
tablets on November 1, 2016 or earlier under certain circumstances.
