ITEM 1.01.            ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On May 30, 2008, NBTY, Inc., entered into an Asset Purchase Agreement (the “Agreement”) for the purchase of substantially all of the assets of Leiner Health Products, Inc. (“Leiner”) for $230 million plus assumption of certain liabilities.  The Agreement is subject to higher or better offers that may be submitted by competing bidders in connection with a process conducted under the supervision of the bankruptcy court presiding over Leiner’s chapter 11 bankruptcy case.  If a higher or better offer is submitted, an auction will be conducted on June 9, 2008, in which case the terms of the Agreement may change.

The Agreement provides for a purchase price adjustment downward if the amount of actual working capital at closing is less than $116.5 million, and for a purchase price adjustment upward if the amount of actual working capital at closing is greater than $126.5 million. Simultaneously with the execution of the Agreement, NBTY and Leiner also entered into an escrow agreement pursuant to which a portion of the purchase price is held in escrow until the closing of the purchase transaction. In addition to the bankruptcy court process, the transaction is subject to regulatory and other customary approvals.  If no higher or better offer is submitted by a competing bidder, the purchase transaction contemplated by the Agreement is expected to close no later than September, 2008.
