Item 2.  Acquisition or Disposition of Assets.
- ------   ------------------------------------

      On June 10, 2004, we acquired all of the capital stock of Kali
Laboratories, Inc., or Kali, a privately-held research and development company
located in Somerset, New Jersey, under a stock purchase agreement, as amended,
that we entered into with Kali, VGS Holdings, Inc. and the shareholders of Kali
(we refer to the stock purchase agreement as the Agreement). The purchase price
of the acquisition was $130 million in cash, warrants with a deemed value of $5
million. The Kali shareholders may be entitled to up to an additional $10
million based upon certain product related performance criteria.

      Kali's business consists of a leased facility in Somerset, New Jersey,
inventory, intellectual property and other assets related to the manufacture,
sale, research and development of pharmaceutical products. Kali currently has 25
pharmaceutical products in development and has filed 14 abbreviated new drug
applications for approval by the United States Food and Drug Administration.
Kali will be operated by us as a wholly-owned subsidiary.

      In determining the purchase price of Kali, we considered, among various
factors, the prices of comparative businesses and the estimated cost and time
required to start and operate a business comparable to Kali's. The purchase
price was determined also on the basis of the negotiated terms and conditions
contained in the Agreement and the projected cash flows of the products that
Kali has and is anticipated by our management to develop, taking into account
expected synergies between our existing businesses and the assets and businesses
to be acquired. The acquisition was financed by cash-on-hand and is not
expected to have a material adverse effect on earnings in 2004 and will be
accounted for using the purchase method.

      Dr. Veerappan Subramanian, the founder and President of Kali, will
continue as President of Kali and he will become Executive Vice President of Par
Pharmaceuticals, Inc., another wholly-owned subsidiary of ours. We have entered
into a 30-month employment arrangement with Dr. Subramanian with appropriate
non-competition provisions and stock option grants.

      The above description is a summary of the principal terms of the
Agreement, as amended. A complete copy of the Agreement was attached as an
exhibit to a Form 8-K filed April 13, 2004. The First Amendment to the
Agreement, dated as of June 9, 2004, is attached to this Form 8-K as an exhibit.
Our description of the terms and conditions of the Agreement, as amended, is
qualified in its entirety by, and subject to, reference to such exhibits.

      On June 10, 2004, the Registrant issued a press release announcing that it
had acquired Kali. The press release is attached hereto as Exhibit 99.1 and is
incorporated herein by reference.
