THIS RECAPITALIZATION AGREEMENT AND PLAN OF MERGER (this “Agreement”) is entered into as of April 15, 2004, by and among Leiner Health Products Inc., a Delaware corporation (the “Company”) and Leiner Merger Corporation, a Delaware corporation (“Leiner Merger Corp.”). Capitalized terms used herein have the meanings set forth in Article X.

WHEREAS, certain stockholders of the Company have agreed to contribute shares of common stock of the Company to Leiner Merger Corp. in exchange for shares of common stock of Leiner Merger Corp. (the “Stock Contributions”) and certain purchasers (“Purchasers”) of new equity have agreed to subscribe for new equity of Leiner Merger Corp.;

WHEREAS, the Board of Directors of the Company approved and declared it advisable and in the best interests of the stockholders of the Company to recapitalize the Company and to effect the merger of Leiner Merger Corp. with and into the Company, with the Company as the surviving corporation, in accordance with the General Corporation Law of the State of Delaware, as amended (the “DGCL”) upon the terms and subject to the conditions set forth herein;

WHEREAS, the Board of Directors of Leiner Merger Corp. approved and declared it advisable and in the best interests of the stockholders of the Leiner Merger Corp. to effect the merger of Leiner Merger Corp. with and into the Company, with the Company as the surviving corporation, in accordance with the DGCL upon the terms and subject to the conditions set forth herein; and

WHEREAS, immediately following the execution and delivery of this Agreement, a majority of the voting power represented by all outstanding shares of all classes of capital stock of the Company will execute and deliver written consents adopting this Agreement and approving the Merger (the “Leiner Consent”).

NOW, THEREFORE, in consideration of the premises and the mutual covenants herein set forth, the parties agree as follows:

(a) Merger Corp. Stock Purchase. On the terms and subject to the conditions of this Agreement, at the Closing and prior to the Effective Time, Leiner Merger Corp. shall, in consideration for the investment by each Purchaser of the amount set forth in the subscription agreement entered into as of the date of this Agreement among Leiner Merger Corp. and each such Purchaser (the “Subscription Agreement”), issue, transfer, deliver and sell to each Purchaser, and each Purchaser shall receive from Leiner Merger Corp. (the “Stock Purchase”), such Purchaser’s portion of newly issued shares (the “Purchasers Merger Corp. Shares”) of Common Stock, par value $0.01 per share, of Leiner Merger Corp. (“Leiner Merger Corp. Common Stock”) pursuant to the terms of the Subscription Agreement.

(b) Working Capital Adjustments. On the seventh Business Day prior to the anticipated Closing Date, the Company shall deliver to Leiner Merger Corp. a certificate certified by the chief financial officer of the Company (“CFO Certificate”) setting forth the Company’s good faith estimate, as of the Closing Date, of Net Working Capital (“Estimated Net Working Capital”).

(c) Working Capital Adjustment Procedures. Upon delivery of the CFO Certificate by the Company, the Company shall provide Leiner Merger Corp. and its representatives with access to the officers, employees and books and records of the Company and each of its Subsidiaries in order to allow Leiner Merger Corp. to verify the accuracy of such Estimated Net Working Capital. Prior to the anticipated Closing Date, Leiner Merger Corp. and the Company will use their respective reasonable best efforts to mutually agree on the estimate, as of the Closing Date, of the Net Working Capital. In the event the Company and Leiner Merger Corp are unable to agree on the estimate, as of the Closing Date, of the Net Working Capital, all items in dispute will be discussed among the senior officers of the parties and their respective accounting representative. If such parties are unable to resolve the dispute, all items in dispute shall be submitted by the parties to the New York office of Deloitte & Touche LLP (the “Neutral Auditor”) at least two Business Days prior to the anticipated Closing Date. The parties shall instruct the Neutral Auditor to render its reasoned written decision as soon as practicable, but in no event later than 14 days after its engagement. The Neutral Auditor shall act as an arbitrator to determine only those items in dispute and shall determine whether the Company’s position or Leiner Merger Corp.’s position is correct with respect to the disputed items. If the parties do not engage the Neutral Auditor, the Estimated Net Working Capital shall become the Closing Net Working Capital as of the Closing Date. If the parties engage the Neutral Auditor, the Net Working Capital, as of the Closing

Date, as determined by the Neutral Auditor shall be the Closing Net Working Capital. The Closing Date will not occur until the amount of Closing Net Working Capital is finally determined pursuant to this Section 1.1(c). All fees and expenses relating to the work, if any, performed by the Neutral Auditor shall be borne by the Surviving Corporation; provided that 50% of such fees and expenses shall be treated as a Sellers’ Expense.

(d) Merger. On the terms and subject to the conditions of this Agreement and in accordance with the applicable provisions of the DGCL, at the Effective Time, which shall be after the consummation of the Stock Purchase and the Stock Contributions, Leiner Merger Corp. shall be merged with and into the Company and the separate corporate existence of Leiner Merger Corp. shall cease (the “Merger”). After the Merger, the Company shall continue as the surviving corporation (sometimes hereinafter referred to as the “Surviving Corporation”) and shall continue to be governed by the laws of the State of Delaware.
