Form of Stock Option Agreement under the Companys Fourth Amended and Restated 2002 Equity Incentive Plan

Pursuant to your grant notice (the “Grant Notice”) and this Stock Option Agreement (the “Agreement”), Impax Laboratories, Inc. (the “Company”) has granted you (the “Optionee”) a nontransferable option under the Company’s Fourth Amended and Restated 2002 Equity Incentive Plan, as the same may from time to time be amended (the “Plan”), to purchase the number of shares (the “Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”), indicated in the Grant Notice (collectively, the “Option”).

1.    Grant of Option. The Company has granted Optionee a nontransferable Option to purchase the number of Shares of the Company’s Common Stock as indicated in the Grant Notice at the exercise price set forth in the Grant Notice. In consideration of the grant of the Award pursuant hereto, Optionee agrees to render faithful and efficient services to the Company or any Affiliate.

If designated as an Incentive Stock Option by the Company in the Grant Notice, this Option is intended to qualify as an “incentive stock option” (“ISO”) within the meaning of Section 422 of the Code to the maximum extent permitted by law and in the event this Option is in any way inconsistent with the legal requirements of the Code or the regulations thereunder for an ISO, this Option shall be deemed automatically amended as of the date hereof to conform to such legal requirements, if such conformity may be achieved by amendment. To the extent that the number of Shares subject to this Option which are exercisable for the first time in any calendar year exceed the $100,000 limitation contained in Section 422(d) of the Code, this Option will not be considered an Incentive Stock Option.

2.    Right to Exercise. During Optionee’s continuous service with the Company or any of its Affiliates (hereinafter “Continuous Service”), this Option shall vest and become exercisable in accordance with the terms of the Grant Notice. Subject to earlier termination, to the extent that this Option has become vested and exercisable with respect to the Shares covered thereby, this Option may thereafter be exercised by Optionee, in whole or in part, at any time or from time to time prior to the date of the expiration of this Option.

3.    Restriction on Exercise. This Option may not be exercised unless such exercise is in compliance with the Securities Act and the regulations promulgated thereunder and all applicable state securities laws as they are in effect on the date of exercise, and the requirements of any stock exchange or national market system on which the Company’s Common Stock may be listed at the time of exercise.

4.    Termination of Service. Except as provided below in this Section 4, this Option shall terminate and may not be exercised if Optionee’s Continuous Service is terminated for any reason whatsoever. Optionee’s service shall not be deemed to have terminated if Optionee is transferred from the Company to one of its Affiliates, or vice versa, or from one of the Company’s Affiliates to another one of the Company’s Affiliates. The Board, or the Committee, if applicable, shall have discretion to determine whether Optionee’s Continuous Service with the Company or any of its Affiliates has terminated and the effective date on which such termination occurred (the “Termination Date”).

4.1    Death/Disability. If Optionee’s Continuous Service is terminated due to death or Disability, that portion of this Option that is exercisable (minus the number of Shares previously purchased upon exercise of this Option) on the Termination Date shall remain exercisable until the earlier of the date of the expiration of this Option or the first anniversary of the Termination Date and, to the extent not exercised during such period, shall thereupon terminate. Optionee’s executor, administrator, guardian or custodian, as the case may be, must present proof of his or her authority satisfactory to the Company prior to being allowed to exercise this Option.

4.2    Other Termination. If Optionee’s Continuous Service terminates for any reason other than death, Disability, or Cause, that portion of this Option that is exercisable (minus the number of Shares previously purchased upon exercise of this Option) on the Termination Date shall remain exercisable until the earlier of the date of the expiration of this Option or the end of the 30 day period commencing on the Termination Date and, to the extent not exercised during such period, shall thereupon terminate.

4.3    Cause. Notwithstanding anything herein to the contrary, if Optionee’s Continuous Service is terminated for Cause (or the Optionee’s Continuous Service terminates at a time when grounds for a termination for Cause exist), this Option (whether or not otherwise vested) shall terminate and cease to be exercisable in its entirety as of the Termination Date.

5.    Change of Control. The following shall apply in the event of a change of control.

5.1    Dissolution or Liquidation. In the event of a dissolution or liquidation of the Company, then this Option shall terminate if not exercised immediately prior to, or simultaneous with, such event.

5.2    Asset Sale, Merger, Consolidation or Reverse Merger. In the event of (i) a sale of all or substantially all of the assets of the Company, (ii) a merger in which the Company is not the surviving corporation, or (iii) a reverse merger in which the Company is the surviving corporation but the shares of Common Stock of the Company outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise, then any surviving corporation or acquiring corporation shall assume this Option, if outstanding under the Plan, or shall substitute a similar award (including an award to acquire the same consideration paid to the stockholders in the transaction described in this Section 5.2 for this Option, if outstanding under the Plan). In the event any surviving corporation or acquiring corporation refuses to assume this Option or to substitute similar awards for this Option, if outstanding under the Plan, then the vesting of this Option shall be accelerated in full and may be exercised with respect to up to 100% of the total number of Shares then subject to this Option minus the number of Shares previously purchased upon exercise of this Option, and this Option shall terminate if not exercised at or prior to such event, provided that if this Option is subject to performance-based vesting, this Option will vest based on the higher of (a) actual performance as of immediately prior to such event or (b) target performance, prorated based on a shortened performance period as of immediately prior to such event.

5.3    Other Change of Control. In the event of the happening of any of the following events: (i) a change within a twelve-month period in the holders of more than 50% of the outstanding voting stock of the Company (other than by means provided for in Section 5.2 above and as provided for in Section 10.3 of the Plan); or (ii) any other event deemed to constitute a “Change of Control” (other than by means provided for in Sections 5.1 and 5.2 above and as provided for in Sections 10.2 and 10.3 of the Plan) by the Board, or the Committee, as applicable, then the vesting of this Option shall be accelerated in full and may be exercised with respect to up to 100% of the total number of Shares then subject to this Option minus the number of Shares previously purchased upon exercise of this Option, and this Option shall terminate if not exercised at or prior to such event.

6.    Manner of Exercise.

6.1    Exercise. To the extent exercisable under the provisions of this Option, this Option may be exercised by delivery to the Company of an executed written notice of exercise to the Company’s Chief Trading Compliance Office if the Optionee is in the position of Senior Director or higher (or otherwise so designated to do so by the Company) or by electronic notice to the Company’s broker if the Optionee is below the position of Senior Director (or not so designated by the Company), in each case, stating the number of full Shares with respect to which it is being exercised, and accompanied by payment of the exercise price for the number of Shares being purchased, together with payment of the amount, if any, required by the Company to satisfy its tax withholding obligations resulting from such exercise.

6.2    Payment of Exercise Price. To the extent permitted by applicable law, payment for the Shares may be made (i) in cash (or by check), (ii) by delivery (physically or by attestation) of shares of Common Stock of the Company having a Fair Market Value equal to the exercise price of this Option that have been owned by Optionee for such period of time, if any, necessary to avoid giving rise to an accounting charge (and which have been paid for within the meaning of Rule 144 promulgated under the Securities Act and, if such shares were purchased from the Company by use of a promissory note, such note has been fully paid with respect to such shares), or were obtained by Optionee in the open public market and are free and clear of all liens, security interests and third-party claims and accompanied by an assignment of such shares of Common Stock to the Company, (iii) at the discretion of the Board or the Committee, as applicable, by a “net exercise” method under which the Company reduces the number of shares issued upon exercise of this Option by the largest whole number of shares with a Fair Market Value as of the date of exercise that does not exceed the aggregate exercise price, (iv) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds, or (v) in any other manner as determined by the Board, or the Committee, as applicable.

6.3    Withholding Taxes.

6.3.1    Optionee hereby authorizes the Company to withhold from payroll and any other amounts payable to Optionee, and Optionee otherwise agrees to make adequate provision for (including by means of a cashless exercise to the extent permitted by the Company), any sums required to satisfy the federal, state, local, foreign, and any other tax withholding obligations of the Company or any of its Affiliate, if applicable, which arise in connection with this Option.

6.3.2    Upon Optionee’s request, subject to compliance with any applicable conditions or restrictions of law and at the discretion of the Board or Committee, as applicable, the Company may (but shall be under no obligation to) withhold from Shares otherwise issuable to Optionee upon the exercise of this Option, a number of whole Shares having a Fair Market Value, determined by the Company as of the date of exercise, to satisfy the tax withholding obligations of the Company (which shall be at a rate not in excess of the maximum individual statutory tax rate) or any of its Affiliates, as applicable.

6.3.3    If this Option is an Incentive Stock Option, by exercising this Option, Optionee agrees that he or she will notify the Company in writing within fifteen (15) days after the date of any disposition of any of the Shares that occurs within two (2) years after the date of this Option grant or within one (1) year after Shares are transferred upon exercise of this Option, and will otherwise provide the Company with such other information as the Company shall reasonably request.

6.4    Issuance of Shares/Stockholder Rights. Provided that such notice and payment are in form and substance satisfactory to the Company and counsel for the Company, the Company has received payment for the Shares and the applicable tax withholding obligations with respect to the exercise has been made or provided for, the Company shall cause the Shares to be issued in the name of Optionee or Optionee’s legal representative. Neither Optionee nor any person entitled to exercise Optionee’s rights in the event of death will have any of the rights of a stockholder with respect to the Shares except to the extent that certificates for such Shares shall have been issued upon the exercise of this Option.

7.    Nontransferability of Option. This Option may not be transferred in any manner other than by will or by the law of descent and distribution and may be exercised during the lifetime of Optionee only by Optionee.

8.    Independent Tax Advice. Optionee agrees that Optionee has or will obtain the advice of independent tax counsel regarding the federal and state income tax consequences of the receipt and exercise of this Option and of the disposition of Shares acquired upon exercise hereof, including advice regarding the imposition of the alternative minimum tax on tax preferences generated by exercise of stock options and regarding any holding period requirements for preferential tax treatment. OPTIONEE ACKNOWLEDGES THAT HE OR SHE HAS NOT RELIED AND WILL NOT RELY UPON ANY ADVICE OR REPRESENTATIONS BY THE COMPANY OR BY ITS EMPLOYEES OR REPRESENTATIVES WITH RESPECT TO THE TAX TREATMENT OF THIS OPTION OR ANY SHARES ISSUED PURSUANT HERETO.

9.    Optionee Service. Nothing in this Agreement shall limit the right of the Company or any of its Affiliates to terminate the Optionee’s service as an officer, employee, director or consultant of the Company or otherwise impose upon the Company or any of its Affiliates any obligation to employ or accept the services of the Optionee.
