to the restrictions on the disposition of Common Stock set forth in the
respective trust agreements (as described in Item 6).

         Other than as set forth above, none of the Reporting Persons has any

      STOCK, T & S REALTY, 9831 PICO PARTNERS AND OTHERS AND RELATED MATTERS

      A.    AGREEMENT WITH THEODORE ROSENBERG AND THE THEODORE ROSENBERG TRUST.
            Trustor, both individually and as trustor of this trust has entered
            into an agreement with Theodore Rosenberg and the Theodore
            Rosenberg Trust which provides that this Trust and the Theodore
            Rosenberg Trust will both contain this section. The agreement
            further provides that this section shall not be changed in either
            Trust during the joint lifetime of Sydney J. Rosenberg and Theodore

            After the death of either of them, this section shall not be
            changed in either of the Trusts.

      B.    MATTERS IN COMMON WITH THEODORE ROSENBERG AND THE THEODORE ROSENBERG
            TRUST. Within the Trust Estate, there are significant interests in
            ABM, T & S Realty Co., 9831 Pico Partners and other investments that
            are owned in conjunction with Trustor's brother, namely Theodore
            Rosenberg or The Theodore Rosenberg Trust. With regard to these
            investments and to other matters of mutual interest, Trustor urges
            the Trustees of All Trusts to act in concert with Theodore
            Rosenberg, the Theodore Rosenberg Trust, and the respective
            successors, trustees and beneficiaries of Theodore Rosenberg and the
            Theodore Rosenberg Trust.

      C.    CONTINUATION OF TRUST. Trustor recognizes that a large portion of
            the Trust Estate consists of closely-held business interests. The
            continuation of Any Trusts hereunder is hereby authorized for as
            long as may be reasonably necessary, including possibly throughout
            the period of payment of installments of federal estate tax.


                                       1

     D.   UNPRODUCTIVE PROPERTY. Notwithstanding any other provision in this
          Trust Agreement to the contrary: No beneficiary of Any Trust shall
          have the power to compel the Trustees of That Trust to make productive
          or more productive, in terms of ordinary income and/or capital gain,
          any unproductive or under-productive property held in That Trust,
          including but not limited to any common stock and or real property.
          This paragraph is also included in the last Section of this Trust
          solely to show that this provision not only falls within this Section
          VI, but also applies to all of the property within the Trust.

     E.   COMMON STOCK OF ABM OR ITS SUCCESSORS IN INTEREST ("ABM STOCK").

          1.   Subject only to the exceptions set forth in Subsection VI.E.3.
               below, no ABM Stock held in Any Trust may be sold or transferred
               to anyone or distributed to any beneficiary of That Trust until
               January 1, 2006, or until five (5) years have elapsed since the
               death of the last to die of Trustor or Trustor's brother Theodore
               Rosenberg if the five-year period should elapse before January 1,
               2006.

          2.   The foregoing period of time is designated as the "Minimum ABM
               Holding Period". Any trust created pursuant to this Trust
               Agreement which contains ABM Stock and is scheduled to terminate
               in whole or in part during the Minimum ABM Holding Period, with
               distribution free of trust to one or more beneficiaries shall,
               notwithstanding any other provisions of this Trust Agreement,
               continue only with respect to such stock on the same terms and
               conditions, but as if the time for termination did not occur
               until after the expiration of the Minimum ABM Holding Period. If
               a beneficiary shall die prior to such termination, such
               beneficiary's interest shall pass as if the beneficiary had died
               prior to the

                                       2
   5
          age or time for termination and such interest shall continue to be
          held, administered and distributed by the Trustees hereunder for the
          benefit of the beneficiaries thereof. Until expiration of the Minimum
          ABM Holding Period, no distribution or calculation of principal shall
          include any ABM Stock or the value thereof.

     3.   There are no exceptions to the Minimum ABM Holding Period for the
          sale, transfer or distribution of ABM Stock; however ABM Stock may be
          sold for cash or exchanged for other stock prior to expiration of the
          ABM Holding Period, but only if such sale or exchange is:


          a.   in conjunction with the sale or exchange of all or substantially
               all of the ABM Stock owned by Trustor's brother Theodore
               Rosenberg and/or The Theodore Rosenberg Trust; or

          b.   in conjunction with the sale or exchange of all or substantially
               all of the stock of the legal successors to Theodore Rosenberg
               and/or The Theodore Rosenberg Trust after the death of Theodore
               Rosenberg.

     4.   The Minimum ABM Holding Period shall not apply to the proceeds from
          any such sale or exchange of ABM Stock unless the Trustees determine
          in their sole and absolute discretion that the voting securities of
          any other entity received in exchange for ABM Stock constitutes a
          significant block of stock in such other entity, in which case the
          Minimum ABM Holding Period shall remain in effect with respect to such
          other voting securities.

     5.   Trustor understands that any Trustee who is also a stockholder,
          director an/or officer of ABM may have conflicting duties and
          obligations to Any/All Trusts, to other stockholders, directors and
          officers of ABM, and to other persons interested in ABM. Trustor holds
          the Trustee
   6


            harmless from any action or inaction with regard to ABM by that
            Trustee and Any/All Trusts related to ABM, both before and after
            the Minimum ABM Holding Period.

F.    T & S REALTY. The following provisions shall apply to T & S Realty Co.
      which is a California general partnership between This Trust and The
      Theodore Rosenberg Trust, as applicable, held in any trust subsequent to
      Trustor's death:

      1.    Any distributions to or from Any Trust on account of its interest
            in T & S Realty Co. shall, to the fullest extent deemed practical
            by the Trustees, be converted into cash, notes or other
            non-partnership property prior to such distribution. Trustor does
            not intend that the interests per se of Any Trust in T & S Realty
            Co. shall be distributed to any beneficiary.

      2.    In connection with raising funds for estate and any other death
            taxes, expenses and distributions, Trustor directs that, to the
            fullest extent deemed practical by the Trustees, other portions of
            the Trust Estate that are not specifically disposed of or provided
            for in This Trust Agreement shall be utilized for distributions
            before obtaining loans or withdrawals from T & S Realty Co., or
            requiring T & S Realty Co. to sell or refinance any of its real
            properties.

      3.    Portions of the Trust Estate that are specifically disposed of or
            provided for in This Trust Agreement include, but are not limited
            to, the Outright Gifts and ABM Stock.

Trust Agreement to the contrary: No beneficiary of Any Trust shall have the
power to compel the Trustees of That Trust to make productive or more
productive, in terms of ordinary income and/or capital gain, any unproductive or
under-productive property held in That Trust, including but not limited to any
common stock and or real property. This paragraph is also included in the last
Section of this Trust solely to show that this provision not only falls within
this Section VI, but also applies to all of the property within the Trust.

     E.   COMMON STOCK OF ABM OR ITS SUCCESSORS IN INTEREST ("ABM STOCK").

               Period. If a beneficiary shall die prior to such termination,

               shall continue to be held, administered and distributed by the
               Trustees hereunder for the benefit of the beneficiaries thereof.
               Until expiration of the Minimum ABM Holding Period, no

          4.   The Minimum ABM Holding Period shall not apply to the proceeds
               from any such sale or exchange of ABM Stock unless the Trustees
