ITEM 1.01       ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

         The Company amended and restated its Executive Non-Qualified Deferred
Compensation Plan effective as of January 1, 2005. A copy of this plan is
attached as Exhibit 10.1 to this Form 8-K and is incorporated herein by
reference.

         The Impax Laboratories, Inc Executive Non-Qualified Deferred
Compensation Plan ("Plan") is a deferred compensation plan established to permit
certain key employees to defer compensation in excess of the deferral limits
under the Impax 401(k) Plan. Participation in the Plan is limited to certain
executive-level employees and consultants as selected by the Board of Directors.
Participants are eligible to elect deferral contributions of up to 10% of
combined base and bonus compensation. The Company makes a matching contribution
equal to 50% of an employee's deferral contribution; provided however, that the
matching contribution for an employee shall not exceed 5% of the employee's
compensation. The matching contribution is 20% vested after the employee's first
year of service and the vesting percentage increases in increments of 20% for
each subsequent year of service.

         Participants may elect to have their accounts measured by a number of
investment options. Benefits are payable upon the participant's termination of
employment in a lump sum or installments as elected by the participant. Benefits
are also payable upon the occurrence of the participant's death or disability. A
participant may request an early distribution in the event of an "unforeseeable
emergency". The Plan is designed to comply with the applicable provisions of
Section 409A of the Internal Revenue Code.
