         WHEREAS, the Company previously established the National Service

         WHEREAS, in connection with the planned distribution of the shares of

"Spin-Off"), the Company desires to amend the Plan to provide for the transfer
of accounts for certain employees and former employees of Acuity Brands, Inc.
and its subsidiaries to a deferred compensation plan being established by Acuity
Brands, Inc. and to provide for an appropriate adjustment of accounts to reflect
the Spin-Off; and

         WHEREAS, the Company desires to amend the Plan to eliminate the ability
to receive a distribution in shares of common stock of the Company;

         NOW, THEREFORE, for and in consideration of the premises, the Plan is
hereby amended as follows:

                                       1.

         Section 4.3(b)(ii) is hereby amended by deleting the present provision
in its entirety and substituting the following in lieu thereof:

         "The Participant's benefits shall be paid in cash."

                                       2.

         The Plan is hereby amended by inserting the following as a new Section
8.9:

                  "8.9     Spin-Off of Acuity Brands, Inc.

                  (a)      Transfer of Accounts. Pursuant to an Employee
         Benefits Agreement dated as of November 30, 2001, between the Company

         each subaccount) of each Participant who becomes or remains an employee
         of Acuity or its subsidiaries as of November 30, 2001 and of each
         Participant (including Participants and their beneficiaries in pay
         status) who was formerly employed by the businesses transferred to
         Acuity by the Company (including former employees of the corporate
         office of the Company) (collectively, the "Transferred Participants"),
         shall be transferred to the Acuity Brands, Inc. Supplemental Deferred
         Savings Plan ("Acuity Plan") as of November 30, 2001 or as soon as
         practical thereafter. The elections made by Transferred Participants
         under this Plan (including, without limitation, elections regarding
         deferral amounts, timing and manner or payment of benefits, and
         designation of Beneficiaries) shall be carried over and shall apply for
         purposes of the Acuity Plan.

                  (b)      Adjustment of Accounts. To the extent all or any
         portion of the Accounts (and subaccounts) of Participants (other than
         the Transferred Participants described in Section 8.9(a) above) are
         deemed to be invested in Shares of common stock of the Company as of
         November 30, 2001, the Accounts (and subaccounts) shall be adjusted in
         accordance with and in satisfaction of the requirements of Sections
         4.1(b) and (c) as follows:

                           (i)  The number of Shares in such Accounts (and
                  subaccounts) shall first be adjusted to reflect any dividends
                  (other than the distribution of shares of Acuity) between the
                  last Annual Valuation Date and November 30, 2001;

                           (ii) The adjusted number of Shares in such Accounts
                  (and subaccounts) determined under (i) above shall be further
                  adjusted to reflect the Spin-Off by (A) multiplying the number
                  of Shares in each such Account (and subaccounts) by the
                  closing per share price of Company common stock (trading with
                  a due bill) on November 30, 2001, and (B) dividing such dollar
                  amount by the per share price of Company common stock after
                  the spin-off [calculated as the difference between the closing
                  per share prices of Company common stock (trading with a due
                  bill) and Acuity common stock (trading on a when-issued basis)
                  on November 30, 2001 (or such other price or prices as
                  determined by the Plan Administrator to be appropriate and
                  equitable)]. Any additional adjustments to the portion of the
                  Accounts (and subaccounts) invested in Shares on the Annual
                  Valuation Date following the Spin-Off shall only reflect
                  dividends or similar actions after December 3, 2001."
