Exhibit 10.4.3

CENTRAL GARDEN & PET COMPANY

2003 OMNIBUS EQUITY INCENTIVE PLAN

PERFORMANCE-BASED

NONQUALIFIED STOCK OPTION AGREEMENT

1. Grant of Option. Central Garden & Pet Company (the “Company”) hereby grants to                      (the “Employee”) under the Central Garden & Pet Company 2003 Omnibus Equity Incentive Plan (the “Plan”), as a separate incentive in connection with his or her employment and not in lieu of any salary or other compensation for his or her services, a nonqualified stock option to purchase, on the terms and subject to the fulfillment of the performance, vesting and other conditions set forth in this Agreement and the Plan, all or any part of an aggregate of          shares of authorized shares of the Class A Common Stock, at the purchase price set forth in paragraph 2 of this Agreement. The option granted hereby is not intended to be an Incentive Stock Option within the meaning of section 422 of the Internal Revenue Code of 1986, as amended.

2. Exercise Price. The purchase price per share (the “Option Price”) shall be $        , which is the fair market value per share of the Class A Common Stock. The effective date of this Agreement shall be             , 201  . The Option Price shall be payable in shares of the Class A Common Stock of the Company or, in the discretion of the Committee, in the legal tender of the United States or in a combination of such legal tender and such shares.

3. Number of Shares. The number and class of shares specified in paragraph 1 above, and/or the Option Price, are subject to appropriate adjustment in the event of changes in the capital stock of the Company by reason of stock dividends, split-ups or combinations of shares, reclassifications, mergers, consolidations, reorganizations or liquidations. Subject to any required action of the stockholders of the Company, if the Company shall be the surviving corporation in any merger or consolidation, the option granted hereunder (to the extent that it is still outstanding) shall pertain to and apply to the securities to which a holder of the same number of shares of Class A Common Stock that are then subject to the option would have been entitled. To the extent that the foregoing adjustments relate to stock or securities of the Company, such adjustments shall be made by the Committee, whose determination in that respect shall be final, binding and conclusive.

4. Commencement of Exercisability. Subject to the fulfillment of the performance conditions set forth on Schedule A to this Agreement, the shares granted under this Option Agreement are exercisable as follows:

5. Termination of Option. In the event of termination of employment with the Company and all Affiliates for any reason other than death, the Employee may, within one (1) month after the date of such termination or             , 201  , whichever shall first occur, exercise the option to the extent the right to exercise the option had accrued as of the date of such termination. If the Employee’s termination of employment is on account of his or her death, or if the Employee shall die within such one (1) month period, the option may be exercised by the Employee’s transferee, as hereinafter provided, to the same extent that the right to exercise the option had accrued immediately prior to the Employee’s death, for a period of two (2) months after the date of the Employee’s death.

6. Persons Eligible to Exercise. The option shall be exercisable during the Employee’s lifetime only by the Employee. The option shall be non-transferable by the Employee other than by a beneficiary designation made in a form and manner acceptable to the Committee, or by will or the applicable laws of descent and distribution.

7. After the Death of Employee. To the extent exercisable after the Employee’s death, the option shall be exercised only by the Employee’s designated beneficiary or beneficiaries as set forth in the Employee’s life insurance enrollment, or if no beneficiary survives the Employee, by the person or persons entitled to the option under the Employee’s will, or if the Employee shall fail to make testamentary disposition of the option, his or her legal representative. A transferee exercising the option must furnish the Company (a) written notice of his or her status as transferee, (b) evidence satisfactory to the Company to establish the validity of the transfer of the option and compliance with any laws or regulations pertaining to said transfer, and (c) written acceptance of the terms and conditions of the option as prescribed in this Agreement.

8. Exercise of Option. The option may be exercised by the person then entitled to do so as to any shares which may then be purchased (a) by giving written notice of exercise to the Company, specifying the number of full shares to be purchased and (b) if requested by the Company, by confirming in writing that the shares to be purchased upon the option exercise are being acquired for investment and not with a view to distribute them.

The Option Price upon exercise of any option shall be payable by having the Company withhold shares of Class A Common Stock having a value equal to the amount required to be withheld or by delivering to the Company already-owned shares to satisfy the Option Price, pursuant to such procedures as the Company may specify from time to time. The Company, in its sole discretion, also may permit (a) the Employee to pay the Option Price in full in cash, or (b) by any other means which the Company, in its sole discretion, determines to both provide legal consideration for the shares, and to be consistent with the purposes of the Plan. The value of the shares to be withheld or delivered will be based on their Fair Market Value on the date of exercise.

9. Suspension of Exercisability. If at any time the Company shall determine, in its discretion, that the listing, registration or qualification of the shares covered by the option upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory authority, is necessary or desirable as a condition of the purchase of shares hereunder, the option may not be exercised, in whole or in part, unless and until such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Company. The Company shall make reasonable efforts to meet the requirements of any such state or federal law or securities exchange and to obtain any such consent or approval of any such governmental authority.

10. No Rights of Stockholder. Neither the Employee nor any person claiming under or through said Employee shall be or have any of the rights or privileges of a stockholder of the Company in respect of any of the shares issuable upon the exercise of the option, unless and until certificates representing such shares shall have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to Employee.

11. Option has No Effect on Employment. The terms of Employee’s employment shall be determined from time to time by the Company, or the Subsidiary employing the Employee, as the case may be, and the Company, or the Subsidiary employing the Employee, as the case may be, shall have the right, which is hereby expressly reserved, to terminate or change the terms of the employment of the Employee at any time for any reason whatsoever, with or without good cause.

12. Addresses for Notices.

Any notice to be given to the Employee shall be addressed to the Employee address set forth beneath the Employee’s signature hereto, or at such other address as the Employee may hereafter designate in writing. Any such notice shall be deemed to have been duly given if and when enclosed in a properly sealed envelope, addressed as aforesaid, registered or certified and deposited, postage and registry fee prepaid, in a United States post office.
