THIS AGREEMENT, made as of                      (the “Grant Date”), between Zep
Inc., a Delaware corporation (the “Company”), and
                                         (the “Optionee”).

WHEREAS, the Company has adopted the Zep Inc. Long-Term Incentive Plan (the
“Plan”) in order to provide additional incentive to certain officers, key
employees and nonemployee directors of the Company and its Subsidiaries; and

WHEREAS, the Optionee performs services as a nonemployee director of the
Company; and

WHEREAS, the Committee responsible for administration of the Plan has determined
to grant the Option to the Optionee as provided herein.

NOW, THEREFORE, the parties hereto agree as follows:

 

  1. Grant of Option.

1.1 The Company hereby grants to the Optionee the right and option (the
“Option”) to purchase all or any part of an aggregate of              whole
Shares subject to, and in accordance with, the terms and conditions set forth in
this Agreement and the Plan.

1.2 The Option is not intended to qualify as an Incentive Stock Option within
the meaning of Section 422 of the Code.

subject to, the provisions of the Plan (the provisions of which are incorporated
herein by reference) and, except as otherwise expressly set forth herein, the
capitalized terms used in this Agreement shall have the same definitions as set
forth in the Plan.

1.4 The Option is conditioned upon Optionee’s execution of this Agreement. If
the Agreement is not executed by the Optionee, the Option may be canceled by the
Committee.

 

  2. Purchase Price.

The price at which the Optionee shall be entitled to purchase Shares upon the
exercise of the Option shall be              per Share.

--------------------------------------------------------------------------------

  3. Duration of Option.

The Option shall be exercisable to the extent and in the manner provided herein
for a period of ten (10) years from the Grant Date (the “Exercise Term”);
provided, however, that the Option may be earlier terminated as provided in
Sections 1.4 and 6 hereof.

 

  4. Vesting and Exercisability of Option.

The Option shall vest, and may be exercised, with respect to the Shares as set
forth in the Optionee Statement attached hereto and made a part hereof, subject
to earlier termination of the Option as provided in Sections 1.4 and 6 hereof or
in the Plan. The right to purchase the Shares as they become vested shall be
cumulative and shall continue during the Exercise Term unless sooner terminated
as provided herein.

 

  5. Manner of Exercise and Payment.

5.1 Subject to the terms and conditions of this Agreement and the Plan, the
Option may be exercised by either (i) delivery of written notice to the Company,
at its principal executive office or (ii) online notice given to an online
broker with which the Company has made arrangement for the exercise of employee
stock options, which notice satisfies the form and conditions set forth in such
arrangement, which shall be provided to the Grantee from time to time. Such
notice shall state that the Optionee is electing to exercise the Option and the
number of Shares in respect of which the Option is being exercised and, if
delivered in writing to the Company, shall be signed by the person or persons
exercising the Option. If requested by the Committee, such person or persons
shall (i) deliver this Agreement to the Secretary of the Company who shall
endorse thereon a notation of such exercise and (ii) provide satisfactory proof
as to the right of such person or persons to exercise the Option.

5.2 The notice of exercise described in Section 5.1 shall be accompanied by the
full purchase price for any Shares purchased pursuant to the exercise of an
Option and shall be paid in full upon such exercise, (i) in cash, by check, by
transferring Shares to the Company or by attesting to the ownership of Shares,
upon such terms and conditions as may be acceptable to the Committee or (ii) by
such arrangement as is made by the Company with the designated online broker.
Any Shares the Optionee transfers to the Company or attests to owning as payment
of the purchase price under an Option shall be valued at their Fair Market Value
on the day preceding the date of exercise of such Option.

5.2 Upon receipt of notice of exercise and full payment for the Shares in
respect of which the Option is being exercised, the Company shall, subject to
Section 15 of the Plan, take such action as may be necessary to effect the
transfer to the Optionee of the number of Shares as to which such exercise was
effective.

5.3 The Optionee shall not be deemed to be the holder of, or to have any of the
rights of a holder with respect to any Shares subject to the Option until
(i) the Option shall have been exercised pursuant to the terms of this Agreement
and the Optionee shall have paid the

full purchase price for the number of Shares in respect of which the Option was
exercised, (ii) the Company shall have issued and delivered the Shares to the

of record on the books of the Company, whereupon the Optionee shall have full
voting and other ownership rights with respect to such Shares.

subject to the Option and the purchase price for such Shares or other stock or
securities. The Committee’s adjustment shall be made in accordance with the
provisions of Section 4(d) of the Plan and shall be effective and final,
