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

     As of April 2, 2004, Pharmaceutical Resources, Inc. (the "Registrant")
entered into a stock purchase agreement with Kali Laboratories, Inc. ("Kali"),
VGS Holdings, Inc. and the shareholders of Kali (the "Kali Shareholders") to
acquire all of the capital stock of Kali, a privately-held research and
development company located in Somerset, New Jersey.

     The stock purchase agreement requires the Registrant to pay to the Kali
Shareholders approximately $135,000,000 in cash and warrants to purchase shares
of the Registrant's common stock and up to $10,000,000 of contingent cash
consideration. The cash purchase price is subject to reduction, on a
dollar-for-dollar basis, if and to the extent that the cash and cash equivalents
held by Kali as of December 31, 2003 are expended outside of the ordinary course
of its business. The stock purchase agreement contains both customary and
deal-specific representations, warranties, non-compete provisions and other
covenants of Kali and the Kali Shareholders.

     The closing of the proposed acquisition is subject, in addition to other
customary conditions, to obtaining clearance to transfer Kali's facility in
Somerset, New Jersey under the New Jersey Industrial Site Recovery Act and
reaching a mutually satisfactory business arrangement with Perrigo Company. The
stock purchase agreement provides for the payment of a termination fee if a
party seeks to terminate the proposed transaction, except for specified rights
to do so.

     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.

     The Registrant's Board of Directors has authorized its management to
proceed with the proposed transaction. As of the date of this Form 8-K, the
Registrant's management has determined that it is reasonably likely that the
conditions to the closing of the acquisition will be satisfied. Accordingly, the
Registrant is filing this Form 8-K now, prior to a closing.

     In determining the purchase price of Kali, the Registrant 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 stock purchase agreement and the projected cash flows of the
products that Kali has and is anticipated by management of the Registrant to
develop, taking into account expected synergies between the Registrant's
existing businesses and the assets and businesses to be acquired.

     It is presently contemplated that the proposed acquisition will close in
the second quarter of 2004. The Registrant currently intends to finance the
acquisition through the use of available cash.

     If the proposed acquisition is completed, Dr. Veerappan Subramanian will
continue as President of Kali, which will become a wholly-owned subsidiary of
the Registrant, and he will become Executive Vice President of Par



Pharmaceuticals, Inc., another wholly-owned subsidiary of the Registrant. The
Registrant will enter into a 30-month employment arrangement with Dr.
Subramanian with appropriate non-competition provisions and stock option grants.

     If the Registrant completes the proposed acquisition, it presently expects
to operate the business of Kali as a separate subsidiary. The Registrant
currently intends to use the assets of, and to operate, the business to be
acquired in substantially the same manner as Kali is currently using those
assets and operating the business. The Registrant has no present intention of
selling any of those assets or divesting any portion of the business. The
acquisition will be accounted for using the purchase method.

     The above is a summary of the principal terms of the stock purchase
agreement, a complete copy of which is attached to this Form 8-K as an exhibit.
The above description of the terms and conditions of the stock purchase
agreement is qualified in its entirety by, and subject to, reference to such
agreement.

     On April 13, 2004, the Registrant issued a press release announcing that it
had entered into the stock purchase agreement. The press release is attached
hereto as Exhibit 99.1 and is incorporated herein by reference.
