                                ZERO CORPORATION
                            PENSION RESTORATION PLAN
                            ADOPTED JANUARY 19, 1994


1.  TITLE AND EFFECTIVE DATE

     This Plan shall be known as the ZERO Corporation Pension Restoration Plan
(the "Plan"), and shall be effective as of January 1, 1994.

2.  PLAN ADMINISTRATION

     The Plan shall be administered and interpreted by the Corporate Secretary
of ZERO Corporation.

     Subject to the terms of the Plan, the Corporate Secretary shall establish
rules, forms and procedures for the administration of the Plan, and shall
interpret the Plan and make, amend, interpret and enforce all provisions adopted
in connection with the Plan.

3.   ELIGIBILITY

     Participants in the Plan shall be required to be employed in the United
States (except as otherwise designated as set forth below), and shall include
all Corporate officers, and division and subsidiary presidents and general
managers, and such other management employees as may be designated by the
Employee Benefits Committee of the Board of Directors of ZERO Corporation (the
"Participants").

4.   ACTION TO PARTICIPATE

     The Participants under the Plan shall automatically be entitled to
participate in the Plan, with no action being necessary on the part of such
Participants.

5.   BENEFIT FORMULA

     Each Participant under the Plan shall be entitled to receive a contribution
from the Company in an amount which equals the reduction in the benefit
contributions as set forth in Article V of the ZERO Corporation Retirement
Savings Plan (the "Pension Plan") account of such eligible Participant as a
result of contribution limitations established by Internal Revenue Code Sections
415 and/or 401(a)(17) (the "Code").

6.   COMPUTATION AND CREDITING

     On the earlier of the date of separation from employment or December 31 of
each year, the Company shall determine the pension benefit to which the
Participant would be entitled without regard
<PAGE>
 
to the contribution limitations established by the Code.  In addition, the
maximum benefit allowable by the Code for the Participant shall be calculated.
For purposes of determining the maximum benefit allowable and any credits to a
Participant, the term "Compensation" shall be as defined in Section 2.14 of
Article II of the Pension Plan whether or not such Compensation is deferred
under the 1994 ZERO Corporation Executive Deferred Compensation Plan (the "1994
Deferred Compensation Plan").  To the extent that a Participant's benefit may
exceed the Code maximum, any contribution which would have been made under the
Pension Plan on the excess will be credited to the account established for such
Plan Participant under the 1994 Deferred Compensation Plan (the "Bookkeeping
Account") as of the last day of each quarter.  For example:
