         3. Company's Obligations. In consideration for this Agreement, and in
addition to the Release set forth in Paragraph 2 above, the Company agrees that:

     (a) it shall, starting April 3, 2005 through March 31, 2006, pay Spiegler a
         base compensation of $204,100 per year, payable weekly in the gross
         amount of $3925, although Spiegler's services to the Company as CFO and
         Secretary shall cease effective April 1, 2005 upon his retirement;


     (b) it shall, through the earlier of March 31, 2006, or such time as
         Spiegler finds replacement health care and dental coverage, pay the
         COBRA premiums for Spiegler to continue the health and dental coverage
         that he had while actively employed by the Company, after which time,
         Spiegler can continue the COBRA coverage under the terms of COBRA if he
         desires to do so. All other benefits Spiegler enjoyed as an employee
         shall cease on April 2, 2005, and Spiegler shall not be eligible for
         any bonus awarded by the Company under any 2005 or 2006 bonus plan or
         for any stock options issued in 2005 or 2006;

     (c) Spiegler's Executive Life Plan shall continue one year beyond the
         current term, which expires on October 28, 2005 until October 28, 2006;

     (d) Spiegler's Executive Long Term Disability Plan shall continue through
         the current term, which expires on January 10, 2006;

         by Spiegler shall automatically become exercisable;

     (f) the Compensation Committee of the Board of Directors has determined

         will remain in the "Continuous Service" of the Company during the
         Consulting Term referenced in P. 4 below and, accordingly, all of
         Spiegler's outstanding stock options will continue to be exercisable
         throughout the Consulting Term and thereafter for a period ending on
         the earlier of (i) 180 days after the end of the Consulting Term or
         (ii) the Expiration Date of the option;

     (g) Spiegler will be eligible to participate in the Impax Laboratories,
         Inc. Executive Non-Qualified Deferred Compensation Plan ("the Plan")
         pursuant to the terms of the Plan and subject to the approval of the
         Compensation Committee of the Board of Directors; and that he shall be
         entitled to matching contributions as provided in the Plan; and that
         such contributions shall be forfeited in the event Spiegler does not
         comply with the terms of this Agreement; and

     (h) recognizing that the payments for those benefits described in (b), (c)
         and (d) above will result in taxable income to Spiegler, it shall, at
         the end of the 2005 tax year, and at the end of the first quarter of
         2006, pay Spiegler an amount equal to the state and federal tax he will
         owe as a result of the Company's payment for those benefits.

         4. Spiegler's Obligation. In consideration of this Agreement, and in
addition to the release set forth in paragraph 2 above, Spiegler agrees that he
shall:

     (a) make himself available to the Company as a consultant until such time
         as he begins employment with another entity, but in no event shall he
         be obligated to act as a consultant beyond March 31, 2006 ("the
         Consulting Term");

     (b) not solicit, on behalf of himself or any other person or entity, any
         current employees of the Company; (c) for a period of one (1) year

         indirectly, any directly competitive specialty pharmaceutical company,
         unless the Company agrees in writing that Spiegler may do so;

     (d) keep confidential the terms of this Agreement, and not disclose or
         publish same, except in response to a subpoena, or except to his
         immediate family members, his financial advisor, his attorney, or to
         his accountant for the purpose of filing government tax returns;

     (e) make no negative or disparaging comments of any kind about the Company
         to any person or entity; (f) with the exception of the laptop computer

         equipment or documents that have not already been returned; and (g)

any of the provisions of paragraph 4 of this Agreement, in addition to any other
of the Company's rights and remedies, the Company shall immediately cease all
payments or benefits described in paragraph 3 above. Spiegler further
acknowledges that the consideration being provided by the Company is more than
the Employer is required to provide under its normal policies, practices or
Spiegler benefit plans and represents benefits to which Spiegler is not
otherwise entitled.

         6. Covenant Not To Sue. Spiegler warrants that he has not filed any
complaints, charges or claims for relief against the Company with any local,
state or federal court or administrative agency that are currently outstanding.
