         automatically shall receive as of such date only, an Option to purchase
         12,000 shares of Stock, but subject to Section 6.2 (regarding the
         ineligibility of 10 percent ((10%) holders). Each Nonemployee Director

of ABM. No Participant or Beneficiary shall under any circumstances acquire any
property interest in any specific assets of ABM.

EXHIBIT 10.20

Section 3.03. Upon resignation, termination, Retirement or death of a
Participant, the value of the Supplemental Benefits payable to such Participant
or Beneficiary shall be determined with reference to the accrual account
maintained for such Participant.

Section 3.04. Payment of the amount allocated to a Participant shall be deferred
until the occurrence of a Payment Event. If the Participant dies before
receiving any or all of the payments due the Participant, any remaining amount
shall be paid, but not before the Participant would have reached age 65, to the
Beneficiary. After determining the value of the Supplemental Benefit for a
Participant entitled to payment, the Administrator shall arrange to pay 1/120th
of the value of the account to the Participant or Beneficiary each month for a
period of 10 years from the date of the Payment Event. There shall be no gains
or losses allocated to the account during the 10 year period of payment.

Section 3.05. Each Participant shall have the right to designate a Beneficiary
or Beneficiaries who are to succeed to his right to receive future payments
hereunder in the event of his death. In case of a failure of designation or the
death of a designated Beneficiary without a designated successor, distribution
shall be made to the Participant's estate or trust, if a trust for such purpose
is in existence. No designation of Beneficiary shall be valid unless in writing
signed by the Participant, dated, and filed with the Committee. Beneficiaries
may be changed without consent of any prior Beneficiaries.

Section 3.06. The right of a Participant or Beneficiary to receive future
payments hereunder shall be vested at all times; provided, however, that such
right shall be forfeited immediately upon the occurrence of either of the
following events: If the Participant is discharged from employment by ABM or a
subsidiary for acts which, in the opinion of the ABM, constitute embezzlement of
corporate funds or if, following the Participant's termination of employment, it
is determined that he or she has embezzled corporate funds.

Section 3.07. Nothing contained herein shall be deemed to create a trust of any
kind for the benefit of any Participant or Beneficiary, or create any fiduciary
relationship. Funds accrued hereunder shall continue for all purposes to be a
part of the general funds of ABM, and no person other than ABM shall, by virtue
of the provisions of this Plan, have any interest in such funds. To the extent
that any person acquires a right to receive payments from ABM under this Plan,
such right shall be no greater than the right of any unsecured general creditor
of ABM.

Section 3.08. The adoption of this Plan shall not confer upon any employee of
ABM or any of its subsidiaries or Participant any right to continued employment,
nor shall it interfere in any way with the right of ABM or any of its
Subsidiaries to terminate the employment or change the compensation of any of
its employees at any time.

                                                                               3

Administration

Section 4.01. The books and records to be maintained for the purpose of the Plan
shall be maintained by the officers and employees of ABM at its expense and
subject to the supervision and control of the Administrator. ABM shall pay all
expenses of administering the Plan.

Section 4.02. To the extent permitted by law, the right of any Participant or
any Beneficiary in any benefit or to any payment hereunder shall not be subject
in any manner to attachment or other legal process for the debts of such
Participant or Beneficiary; and any such benefit or payment shall not be subject
to anticipation, alienation, sale, transfer, assignment or encumbrance. In the
event that the Plan is presented with an appropriate order from a family court
or other court of competent jurisdiction dividing the right to benefits under
this Plan or to receiving continuing payments under this Plan between the
Participant and the Participant's spouse, the Administrator shall establish such
accounts and sub-accounts and make arrangement for such payments as the order
may require. In no event shall the Plan be required to pay a benefit in a
greater amount or earlier than would otherwise be required by the Plan for
payments to the Participant.

Section 4.03. No member of the Committee or the Administrator and no officer or
employee of ABM shall be liable to any person for any action taken or omitted in
connection with the administration of this Plan unless attributable to his own
fraud or willful misconduct; nor shall ABM be liable to any person for any such
action unless attributable to fraud or willful misconduct on the part of a
director, officer or employee of ABM.

Section 4.04. The Committee shall establish procedures for handling claims for
benefits under the Plan and appeals from denied claims.

ARTICLE V

Amendment of Plan

Section 5.01. The Committee may amend the Plan in whole or in part from time to
time.

Section 5.02. Notice of every such amendment shall be given in writing to each
Participant and Beneficiary of each deceased Participant.
