with the U.S. Borrower, the "BORROWERS"), the various financial institutions as
are or may become parties thereto which extend a Commitment under the U.S.
Facility (collectively, the "U.S. LENDERS"), the various financial institutions
as are or may become parties thereto which extend a Commitment under the
Canadian Facility (collectively, the "CANADIAN LENDERS", and together with the
U.S. Lenders, the "LENDERS"), The Bank of Nova Scotia ("SCOTIABANK") as agent
for the U.S. Lenders under the U.S. Facility (in such capacity, the "U.S.
AGENT"), Scotiabank, as agent for the Canadian Lenders under the Canadian
Facility (in such capacity, the "CANADIAN AGENT", and together with the U.S.

Agent. Unless otherwise defined in this waiver letter (this "WAIVER LETTER") or
the context otherwise requires, terms used in this Waiver Letter have the
meanings provided in the Credit Agreement.



     By this Waiver Letter, the Borrowers hereby request that the Required
Lenders waive, for a limited period ending on the earlier of (x) 5:00 p.m. on
March 30, 2001 and (y) the occurrence of an Event of Default (other than those
referred to in this sentence), the Defaults or Events of Default resulting from
the Borrowers' noncompliance with the financial covenants set forth in Section
9.2.4 of the Credit Agreement for the Fiscal Quarter ending December 31, 2000
and any breach of the representations or warranties under the Loan Documents
made on January 12, 2001 and January 17, 2001 pursuant to Sections 7.2.1 and
7.2.2 of the Credit Agreement. Consequently, we further request that the Lenders
agree not to exercise any of their rights and remedies under the Loan Documents
or under applicable law with respect to such Defaults or Events of Default for
the period specified above.

     In consideration of the waivers and the Lenders' forbearance from
exercising remedies (as described above), the Borrowers agree that they will,
and will cause their Subsidiaries to, comply with the following covenants:

     1.   Promptly and in any event no later than 4:00 p.m. on March 27, 2001,
          the Borrowers will deliver to the Agents a draft of an engagement
          letter which has been fully negotiated by the Borrowers and an
          investment banking firm reasonably satisfactory to the Agents, the
          scope and substance of which shall be satisfactory to the Agents and
          pursuant to which, in any event, such investment banking firm will
          (upon the execution and delivery of such engagement letter) be engaged
          to explore strategic alternatives for the Borrowers and their
          Subsidiaries.

     2.   Commencing on February 20, 2001, no later than 4:00 p.m. on the first
          Business Day of each week, the Borrowers will deliver to the Agents
          updated weekly rolling cash flow forecasts for the following twelve
          week period, together with (commencing on February 27, 2001) an actual
          to forecast variance analysis for the preceding week, which forecasts
          shall also include a certification from an Authorized Officer of the
          U.S. Borrower representing to the information required pursuant to
          paragraph 6 hereof.

     3.   Promptly and in any event no later than 4:00 p.m. on March 23, 2001,
          the Borrowers will deliver to each Lender a preliminary business plan
          (the "BUSINESS PLAN") in form and scope satisfactory to the Agents.

     4.   The Borrowers (and their representatives and management) will meet
          with the Lenders on March 28, 2001 in either Carson, California or New
          York, New York to, among other things, discuss the Business Plan, and
          the Borrowers will, no later than February 28, 2001, inform the Agents
          of the exact time and location of such meeting.

                                      -2-



     5.   As soon as available and in any event within 30 days after the end of
          each month (beginning with 30 days after January 31, 2001), the
          Borrowers will deliver to the Agents consolidated and consolidating
          balance sheets of the U.S. Borrower and its Subsidiaries (including
          consolidating balance sheets of the Canadian Borrower and its
          Subsidiaries) as of the end of such month and consolidated and
          consolidating statements of earnings and cash flow of the U.S.
          Borrower and its Subsidiaries (including consolidating statements of
          earnings and cash flow of the Canadian Borrower and its Subsidiaries)
          for such month and for the period commencing at the end of the
          previous Fiscal Year and ending with the last day of such month;
          PROVIDED that the required financial statements for the month of
          February, 2001 shall be delivered to the Lenders no later than 4:00
          p.m. on March 25, 2001. The Borrowers agree that this covenant shall
          survive termination or expiration of this Waiver Letter.

     6.   The Borrowers will not permit any of the disbursements for any month
          set forth in the Initial Forecast (as defined below) to exceed 110% of
          the amounts set forth therefor in the Initial Forecast and will not
          permit the cash balance at the end of any month to be less than 90% of
          the cash balance set forth in the Initial Forecast for such month.

     7.   The Borrowers agree to cooperate fully with an independent third party
          (i.e., not affiliated with any Obligor) to be engaged by the Lenders
          in its audit and appraisal of the assets of the Borrowers and their
          Subsidiaries and with legal counsel to be engaged by the U.S. Agent
          (or by Mayer, Brown & Platt) to review various litigation issues (the
          "SPECIAL COUNSEL"), in each case at the Borrowers' expense. The
          Borrowers agree that the scope of the audit shall be satisfactory to
          the Agents.

     8.   Promptly and in any event no later than 4:00 p.m. on March 30, 2001,
          the Borrowers will cause each bank or financial institution located in
          the United States or in Canada (each referred to as a "COLLECTING
          BANK") to which any account obligor of either Borrower or any
          Subsidiary deposits payment for goods or services (including accounts
          receivables) to execute and deliver to the Agents "lock-box"
          agreements in form and substance satisfactory to the Agents which will
          provide for, among other things, (i) an acknowledgment by such
          Collecting Bank of the Agents' Lien on all money in such accounts,
          (ii) a waiver of such Collecting Bank's right to set-off (other than
          with respect to items returned for insufficient funds and for
          customary charges payable to such Collecting Bank arising from its
          maintenance of the account and services provided to the applicable
          Borrower or Subsidiary), and (iii) a daily deposit by such Collecting
          Bank into an account maintained with a Lender (or, if agreed to by the
          Agents, a non-Lender that has executed and delivered to the Agents a
          "concentration" account agreement in form and substance satisfactory
          to the Agents which shall include, among other things, the agreements
          set forth in clauses (i) and (ii) of this


                                      -3-




          sentence). In furtherance of the covenants contained in the Loan
          Documents, the Borrowers agree to promptly execute and deliver to the
          Agents all notices (including any notices permitted under the Uniform
          Commercial Code of the State of California) and other documents
          necessary to allow the Agents to perfect their security interests in
          all amounts held with any Collecting Bank or any other institutions
          which hold accounts of the Borrowers or their Subsidiaries.

     9.   Promptly and in any event no later than 4:00 p.m. on February 16,
          2001, the Borrowers will deliver to the Agents a perfection
          certificate in form and scope satisfactory to the Agents, certifying
          as to, among other things, all locations of the Borrowers' and their
          Subsidiaries' assets (other than motor vehicles, but including a list
          of all bank accounts and bank locations, and all intellectual
          property).

     10.  Promptly and in any event no later than 4:00 p.m. on February 16,
          2001, the Borrowers shall execute documentation acceptable to the
          Agents with respect to their grant of a security interest in their
          interests in any judgement, settlement or other proceeds or amounts,
          however characterized, arising from or in connection with any
          anti-trust claims (including the proceedings captioned "Leiner Health
          Products Inc. vs. F. Hoffmann-La Roche, Ltd., et al", case no.
          99-09832) (collectively, the "ANTI-TRUST LITIGATION").

Failure to comply with any of the covenants set forth above shall constitute an
immediate Event of Default.

     In order to induce the Lenders to grant the foregoing waivers and
forbearance from exercising their remedies under the Loan Documents, the
Borrowers hereby

          (a) represent and warrant that, after giving effect to this Waiver
     Letter, all of the statements set forth in Section 7.2.1 of the Credit

     LIBO Rate Loans or Canadian BAs, as applicable, (iii) from and after the
     date of the effectiveness of this Waiver Letter through (and including)
     March 30, 2001, the Applicable Margin shall in each case be increased by 1%

     Agreement, (iv) the Borrowers and their Subsidiaries are prohibited from

                                      -4-



     and (v) the Lenders have a perfected and continuing security interest that
     extends to all proceeds, pursuant to 11 U.S.C.S. 552, which includes, but
     is not limited to, any judgments or amounts of any settlement from the
     Anti-trust Litigation; and

          (c) agree that all interest for Base Rate Loans and Canadian Prime
     Rate Loans shall be payable in arrears on the fifteenth day of each month
     (instead of the Quarterly Payment Dates).

Furthermore, the Borrowers and the Lenders agree that the terms of the
immediately preceding clauses (a) through (c) shall continue to be in full force
and effect unless otherwise consented to by the Required Lenders, and regardless
of the expiration or termination of the waivers described above or this Waiver
Letter.
