ITEM 3.  INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

         The following documents are incorporated by reference in this
registration statement: (i) ABM Industries Incorporated's (the "Company") latest
annual report filed pursuant to Sections 13(a) or 15(d) of the Securities
Exchange Act of 1934 (the "Exchange Act"); (ii) all other reports filed by the
Company pursuant to Sections 13(a) or 15(d) of the Exchange Act since the end of
the fiscal year covered by the Company's latest annual report; and (iii) the
description of the Company's common stock set forth in the Company's
Registration Statement on Form 8-A relating thereto, including any amendment or
report filed for the purpose of updating such description. All documents filed
by the Company after the date of this registration statement pursuant to
Sections 13(a), 13(c), 14, and 15(d) of the Exchange Act, prior to the filing of
a post-effective amendment (that indicates all securities offered have been sold

from the date of filing of such documents.

ITEM 4.  DESCRIPTION OF SECURITIES

Inapplicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

Inapplicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         As authorized by Section 145 of the Delaware Corporation Law, the
Company's Certificate of Incorporation eliminates the personal liability of its
directors to the Company or its stockholders for monetary damages for any breach
of fiduciary duty as a director, except for: (i) any breach of the duty of
loyalty to the Company or its stockholders, (ii) acts or omissions not in good
faith, (iii) intentional misconduct or a knowing violation of law, or (iv) any
transaction from which the director derived an improper personal benefit.

         As authorized by Section 145 of the Delaware Corporation Law, the
Company's By-Laws provide for the indemnification of the directors, officers,
employees or agents of the Company in




                                       2
<PAGE>   3
certain cases. Indemnification shall be provided to directors and officers of
the Company, or of other enterprises if serving at the request of the Company,
against actual and reasonable costs, charges, expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement in connection with
pending or completed actions, suits or proceedings, whether civil, criminal,
administrative or investigative (other than action by or in the right of the
Company) if the director or officer acted in good faith and in a manner
reasonably believed to be in or not opposed to the best interest of the Company,
and, with respect to any criminal action or proceeding, had no reasonable cause
to believe the conduct was unlawful.

         If such proceeding is brought by or on the behalf of the Company, a
similar standard of care is applicable, except that no indemnification shall be
made with respect to any matter as to which such person is adjudged to be liable
to the Company unless and only to the extent that the court shall determine such
person is fairly and reasonably entitled to indemnification of such costs.

         The Company's By-Laws further provide that, notwithstanding the
foregoing, directors, officers, employees and agents shall be indemnified of all
actual and reasonable costs to the extent that such persons are successful on
the merits or otherwise.

                  In addition to the above, the Company has entered into an
Indemnification Agreement with its directors. The Indemnification Agreement
provides directors with the same indemnification by the Company as set forth in
the preceding paragraphs except that the Indemnification Agreement differs from
the By-Laws in the following significant respects: (1) indemnification is
provided to directors in excess of that provided by any insurance coverage; and
(2) no indemnification shall be provided on account of any action commenced by
the director in his or her individual right against the Company, its directors,
officers and stockholders unless authorized by a majority of disinterested
directors.

         There exists directors and officers liability insurance presently
outstanding which insures directors and officers of the Company. The losses
covered by the policy are subject to certain exclusions and the policy contains
certain deductible provisions. All exclusions and deductibles are specifically
indemnified in the Indemnification Agreement discussed in the preceding
paragraph.

ITEM 9.  UNDERTAKINGS

         (a)      The undersigned registrant hereby undertakes:

                  (1) To file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement:

                           (i) To include any prospectus required by section
10(a)(3) of the Securities Act of 1933;

                           (ii) To reflect in the prospectus any facts or events
arising after the effective date of the registration statement (or the most
recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
registration statement;

                           (iii) To include any material information with
respect to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in the registration
statement;

                  Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
not apply if the registration statement is on Form S-3 or Form S-8 and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
section 13 or section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the registration statement.

                                       4
<PAGE>   5
                  (2) That, for the purpose of determining any liability under
the Securities Act of 1933, each such post-effective amendment shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

                  (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933 each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of the
Plan's annual report pursuant to section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                  the Company and its affiliated companies (other than a breach
                  arising from the failure of The Optionee to work as a result
                  of incapacity due to physical or mental illness) and which is
                  not remedied in a reasonable period of time after receipt of
                  written notice from the Company specifying such breach, or

         r. "Rule 16b-3" means Rule 16b-3, as promulgated by The Commission
         under Section 16(b) of The Exchange Act, as amended from time to time.

         s. "Stock" means common stock, par value $0.01 per share, of the
         Company.

         t. "Stock Option" or "Option" means an option granted under Section 5
         of The Plan.

         u. "Termination of Employment" means the termination of an Optionee's
         employment with the Company or any of its Affiliates, excluding any
         such termination where there is a simultaneous reemployment by the
         Company or any of its Affiliates. An Optionee shall be deemed to have
         terminated employment if he or she ceases to perform services for the
         Company or any of its Affiliates on an active full-time basis,
         notwithstanding the fact that such Optionee continues to receive
         compensation or benefits pursuant to an employment contract or other
         agreement or arrangement with the Company or any of its Affiliates. A
         non-medical leave of absence shall, unless such leave of absence is
         otherwise approved by The Committee, be deemed a Termination of
         Employment. An Optionee employed by an Affiliate of the Company shall
         also be deemed to incur a Termination of Employment if that Affiliate
         ceases to be an Affiliate of the Company, as the case may be, and that
         Optionee does not immediately thereafter become an employee of the
         Company or any other Affiliate of the Company.

         In addition, certain other terms have definitions given to them as they
         are used herein.

2.       Administration.

         The Plan shall be administered by the Executive Officer Compensation &
         Stock Option Committee of The Board or such other committee of The
         Board, composed solely of not less than two Non-Employee Directors,
         each of whom shall be appointed by and serve at the pleasure of The
         Board. If at any time no such committee(s) shall be in office, the
         functions of The Committee specified in The Plan shall be exercised by
         The Board.

         The Committee shall have all discretionary authority to administer the
         Plan and to grant Stock Options pursuant to the terms of The Plan to
         senior executives of the Company and any of its Affiliates.

         Among other things, The Committee shall have the discretionary
         authority, subject to the terms of The Plan:

         a. to select the Eligible Persons to whom Stock Options may from time
         to time be granted;

                                       11
<PAGE>   4
         b. to determine the number of shares of Stock to be covered by each
         Stock Option granted hereunder; and

         c. to determine the terms and conditions of any Stock Option granted
         hereunder including, but not limited to, the option price (subject to
         Section 5a of The Plan) and any vesting condition, restriction or
         limitation based on such factors as The Committee shall determine.

         The Committee shall have the authority to adopt, alter and repeal such
         administrative rules, guidelines and practices governing The Plan as it
         shall, from time to time, deem advisable, to interpret the terms and
         provisions of The Plan and any Stock Option issued under The Plan (and
         any agreement relating thereto) and to otherwise supervise the
         administration of The Plan.

         The Committee may act only by a majority of its members then in office,
         except that the members thereof may authorize any one or more of their
         number or any officer of the Company to execute and deliver documents
         on behalf of The Committee.

         Any determination made by The Committee or pursuant to delegated
         authority pursuant to the provisions of The Plan with respect to any
         Stock Option shall be made in the sole discretion of The Committee or
         such delegate at the time of the grant of the Stock Option or, unless
         in contravention of any express term of The Plan, at any time
         thereafter. All decisions made by The Committee or any appropriately
         delegated officer pursuant to the provisions of The Plan shall be final
         and binding on all persons, including the Company and Plan
         participants, and shall be given the maximum deference permitted by
         law.

3.       Stock Subject to Plan.

         Subject to adjustment as provided herein, the total number of shares of
         Stock available for grant under The Plan shall be one million five
         hundred thousand 1,500,000). No individual shall be eligible to receive
         Stock Options to purchase more than 100,000 shares of Stock under The
         Plan. Shares subject to a Stock Option under The Plan may be authorized
         and unissued shares or may be treasury shares.

         If any Stock Option terminates without being exercised, shares subject
         to such Stock Option shall be available for further grants under The
         Plan.

         In the event of any merger, reorganization, consolidation,
         recapitalization, stock dividend, stock split, or extraordinary
         distribution with respect to the Stock or other change in corporate
         structure affecting the Stock, The Committee or The Board may make such
         substitution or adjustments in the number, kind and option price of
         shares authorized or outstanding as Stock Options, and/or such other
         equitable substitution or


                                       12
<PAGE>   5
         adjustments as its may determine to be appropriate in its sole
         discretion; provided, however, that the number of shares subject to any
         Stock Option shall always be a whole number.


4.       Eligibility.

         Senior executives who are actively employed on a full-time basis by the
         Company or any of its Affiliates, and who are responsible for or
         contribute to the management, growth and profitability of the business
         of the Company or any of Affiliates, are eligible to be granted Stock
         Options under The Plan ("Eligible Persons").

5.       Stock Options.

         Any Stock Option granted under The Plan shall be in the form attached
         hereto as Annex "A", which is incorporated herein and made a part of
         The Plan, with such changes as The Committee may from time to time
         approve which are consistent with The Plan. None of the Stock Options
         granted under The Plan shall be "incentive stock options" within the
         meaning of Section 422 of The Code.

         The grant of a Stock Option shall occur on the date The Committee
         selects a Senior Executive of the Company or any of its Affiliates to
         receive any grant of a Stock Option, determines the number of shares of
         Stock to be subject to such Stock Option to be granted to such Senior
         Executive, and specifies the terms and provisions of said Stock Option.
         Such selection shall be evidenced in the records of the Company whether
         in the minutes of the meetings of The Committee or by their consent in
         writing. The Company shall notify an Optionee of any grant of a Stock
         Option, and a written option agreement or agreements shall be duly
         executed and delivered by the Company to the Optionee.

         Stock Options granted under The Plan shall be subject to the following
         terms and conditions and shall contain such additional terms and
         conditions as The Committee shall deem desirable:

         a. Option Price. The option price per share of Stock purchasable under
         a Stock Option shall be the greater of: (i) $20.00 per share, (ii) the
         Fair Market Value per share of Stock on the grant date, or (iii) the
         Fair Market Value per share of Stock on the date of Stockholder
         approval of The Plan .

         b. Option Term. The term of each Stock Option shall be ten (10) years
         from its date of grant, unless earlier terminated.

         c. Exercisability. Except as otherwise provided herein, each Stock
         Option shall be exercisable during its term only if such Stock Option
         has vested, and only after the first (1st) anniversary of its date of
         grant.

                                       13
<PAGE>   6
         d. Vesting. Each Stock Option shall have assigned to it by The
         Committee a vesting price (the "Vesting Price") which will be used to
         provide for accelerated vesting so that such Stock Option will vest
         immediately if, on or before the close of business on the fourth (4th)
         anniversary of its date of grant, the Fair Market Value of the Common
         Stock shall have been equal to or greater than the Vesting Price with
         respect to such Stock Option for ten (10) trading days in any period of
         thirty (30) consecutive trading days. Any Stock Option that has not
         vested on or before the close of business on the fourth (4th)
         anniversary of its date of grant shall vest at the close of business on
         the business day immediately preceding the eighth (8th) anniversary of
         its date of grant, if such Option has not previously terminated.

         e. Method of Exercise. Subject to the provisions of this Section 5 of
         The Plan, Stock Options may be exercised, in whole or in part, by
         giving written notice of exercise to the Company specifying the number
         of shares of Stock subject to the Stock Option to be purchased.

         The option price of Stock to be purchased upon exercise of any Option
         shall be paid in full:

                  (1) in cash (by certified or bank check or such other
                  instrument as the Company may accept),

                  (2) in the discretion of The Committee, in the form of
                  unrestricted Stock already owned by The Optionee for six (6)
                  months or more and based on the Fair Market Value of the Stock
                  on the date the Stock Option is exercised,

                  (3) in any other form approved in the discretion of The
                  Committee, or

                  (4) by any combination thereof.

         In the discretion of The Committee, payment for any shares subject to a
         Stock Option may also be made by delivering a properly executed
         exercise notice to the Company, together with a copy of irrevocable
         instructions to a broker to deliver promptly to the Company the amount
         of sale or loan proceeds to pay the purchase price, and, if requested,
         the amount of any federal, state, local or foreign withholding taxes.
         To facilitate the foregoing, the Company may enter into agreements for
         coordinated procedures with one or more brokerage firms.

         No shares of Stock shall be issued until full payment therefor has been
         made. The Optionee shall have all of the rights of a stockholder of the
         Company holding the Stock that is subject to such Stock Option
         (including, if applicable, the right to vote the share and the right to
         receive dividends), only when The Optionee has given written notice of
         exercise, has paid in full



                                       14
<PAGE>   7
         for such shares and, if requested, has given the representation
         described in Section 9a of The Plan.

         f. Non-transferability of Stock Options. No Stock Option shall be
         transferable by The Optionee other than:

                  (1) to a beneficiary designation satisfactory to The
                  Committee, or

                  (2) by will or by the laws of descent and distribution.

         All Stock Options shall be exercisable, during The Optionee's lifetime,
         only by The Optionee or by the guardian or legal representative of The
         Optionee, it being understood that the terms "holder" and "Optionee"
         include the guardian and legal representative of The Optionee named in
         the option agreement and any person to whom an option is transferred by
         will or the laws of descent and distribution or pursuant to a qualified
         domestic relations order. The Committee may establish such procedures
         as it deems appropriate for an Optionee to designate a beneficiary to
         whom any amounts payable in the event of the Optionee's death are to be
         paid or by whom any rights of the Optionee, after the Optionee's death,
         may be exercised.

         g. Termination by Death, Disability, Retirement or by the Company
         Without Cause. If The Optionee's employment terminates by reason of
         death, Disability or Retirement, or if such employment is terminated by
         the Company without Cause, in each case prior to the vesting of a Stock
         Option held by The Optionee, the following provisions shall apply:

                  (1) if termination occurs by death or Disability, or by the
                  Company without Cause, such Stock Options shall be exercisable
                  only within ninety (90) days of such termination, and only if
                  such Stock Options are then vested;

                  (2) if termination occurs by Retirement or other "voluntary
                  quit," such Stock Options shall terminate immediately; and

         h. Termination by the Company for Cause. If The Optionee's employment
         is terminated by the Company for Cause prior to the vesting of a Stock
         Option, such Stock Options shall terminate immediately.

         i. Termination After Vesting. If The Optionee's employment is
         terminated for any reason after a Stock Option has vested, such Stock
         Options shall be exercisable only within ninety (90) days of such
         termination,

         j. Change in Control Cash Out. Notwithstanding any other provision of
         The Plan, upon the occurrence of a Change of Control



                                       15
<PAGE>   8
         all outstanding Stock Options shall immediately vest and become fully
         exercisable, and during the ninety (90) day period from and after such
         Change in Control (the "Exercise Period"), The Optionee shall have the
         right, in lieu of the payment of the exercise price for the shares of
         Stock being purchased under the Stock Option and by giving notice to
         the Company, to elect (within the Exercise Period) to surrender all or
         part of the Stock Option to the Company and to receive cash, within
         ninety (90) days of such notice, in an amount equal to the amount by
         which the Change in Control Price per share of Stock on the date of
         such election shall exceed the exercise price per share of Stock under
         the Stock Option (the "Spread"), multiplied by the number of shares of
         Stock granted under the Stock Option as to which the right granted
         under this Section 5j of The Plan shall have been exercised.

                  Notwithstanding the foregoing, if any right granted pursuant
         to this Section 5j of The Plan would make a Change in Control
         transaction ineligible for pooling of interests accounting under APB
         No. 16 than but for this Section 5j of The Plan would otherwise be
         eligible for such accounting treatment, The Committee shall have the
         authority to replace the cash payable pursuant to this Section 5j of
         The Plan with Stock having a Fair Market Value equal to the cash that
         would otherwise be payable hereunder. For purposes of this Section 5j
         only, the date of grant of any Stock Option approved by The

                  Committee on December 17, 1996 shall be deemed to be the date
         on which The Plan is approved by the Company's stockholders.

         k. Initial Grants. On December 17, 1996, The Committee granted the
         following Stock Options to the senior executives set forth below, in
         the share amounts and at the Vesting Prices and exercise prices
         indicated, subject to approval by the Stockholders of the Company on
         March 18, 1997:

         for these and any other Options granted under The Plan, the Exercise
         Price shall be the greater of: (i) $20.00 per share, (ii) the Fair
         Market Value per share of Stock on the grant date of any such Options,
         or (iii) the Fair Market Value per share of Stock on the date of
         Stockholder approval of The Plan.

6.        Change in Control Provisions.

         a. Impact of Event. Notwithstanding any other provision of The Plan to
         the contrary, in the event of a Change in Control, any Stock Options
         outstanding as of the date such Change in Control is determined to have
         occurred, and not then vested and exercisable, shall become vested and
         exercisable to the full extent of the original grant, provided that
         such accelerated vesting shall occur only if The Optionee is an active
         full-time employee of the Company or any of its Affiliates as of such
         date.

         b. Definition of Change in Control. For purposes of The Plan, a "Change

                           (c) excluding, however, the following acquisitions of

                                    (iii) any acquisition by any employee

                                    maintained by the Company or any corporate

                                       18
<PAGE>   11
                                    following such reorganization, merger or
                                    consolidation, the conditions described in
                                    Section 6b(3) of The Plan are satisfied; or

                  (2) Individuals who, as of the effective date of The Plan,
                  constitute The Board (the "Incumbent Board") cease for any
                  reason to constitute at least a majority of The Board;
                  provided, however, that any individual who becomes a member of
                  The Board subsequent to such effective date, whose election,
                  or nomination for election by the Company's shareholders, was
                  approved by:

                           (a) a vote of at least a majority of Directors then

                           then constituting the Executive Committee of The

                           least five members and all members of such Committee
                           were either members of the Incumbent Board of
                           considered as being members of the Incumbent Board,
                           pursuant to Section 6b(2)(a), shall be considered as
                           though such individual were a member of the Incumbent
                           Board; but, provided further, that any such
                           individual whose initial assumption of office occurs
                           as a result of either an actual or threatened
                           election contest (as such terms are used in Rule
                           14a-11 of Regulation 14A promulgated under The
                           Exchange Act) or other actual or threatened
                           solicitation of proxies or consents by or on behalf
                           of a Person other than The Board shall not be so
                           considered as a member of the incumbent Board; or

                  (3) Approval by the shareholders of the Company of a
                  reorganization, merger or consolidation or sale or other
                  disposition of all or substantially all of the assets of the
                  Company ("Business Combination"); excluding, however, such a
                  Business Combination pursuant to which:

                           (a) all or substantially all of the individuals and
                           entities who are the beneficial owners, respectively,

                           indirectly, more than sixty percent (60%) of,
                           respectively, the outstanding shares of common stock,
                           and the combined voting power of the then outstanding
                           voting securities entitled to vote generally in the
                           election of directors, as the case may be, of the
                           corporation resulting from such Business Combination
                           (including, without limitation, a corporation which
                           as a result of such transaction owns the Company or
                           all or substantially all of the Company's assets

                           ownership, immediately prior to such Business
                           Combination, of the Outstanding Company Common Stock
                           and Outstanding Company Voting Securities, as the
                           case may be,

                           (b) no Person (other than the Company, any employee
                           benefit plan (or related trust) sponsored or
                           maintained by the Company or any corporation
                           controlled by the Company or such corporation
                           resulting from such Business Combination and any
                           Person beneficially owning, immediately prior to such
                           Business Combination, directly or indirectly, twenty
                           percent (20%) or more of the Outstanding Company
                           Common Stock or Outstanding Company Voting
                           Securities, as the case may be) will beneficially
                           own, directly or indirectly, twenty (20%) or more of,
                           respectively, the outstanding shares of common stock
                           of the corporation resulting from such Business
                           Combination or the combined voting power of the
                           outstanding voting securities of such corporation
                           entitled to vote generally in the election of
                           directors, and

                           (c) at least a majority of the members of the board
                           of directors of the corporation resulting from such
                           Business Combination were members of the Incumbent
                           Board at the time of the execution of the initial
                           agreement, or of the action of The Board, providing
                           for such Business Combination; or

                  (4) The approval by the shareholders of the Company of a
                  complete liquidation or dissolution of the Company.

         c. Change in Control Price. For purposes of The Plan, "Change in
         Control Price" means the higher of:

                  (1) the highest reported sales price, regular way, of a share
                  of Stock in any transaction reported on the New York Stock
                  Exchange Composite Tape or other national securities exchange
                  on which such shares are listed or on NASDAQ, as applicable,
                  during the ninety (90) day period prior to and including the
                  date of a Change in Control, and or

                  (2) if the Change in Control is the result of a tender or
                  exchange offer or a Business Combination, the highest price
                  per share of Stock paid in such tender or exchange offer or
                  Business Combination; provided, however, that in the case of a
                  Stock Option which:

                           (a) is held by an Optionee who is an officer of the
                           Company and is subject to Section 16(b) of The
                           Exchange Act, and


                                       20
<PAGE>   13
                           (b) was granted within two hundred and forty (240)
                           days of the Change in Control,

                           then the Change in Control Price for such Stock
                           Option shall be the Fair Market Value of the Stock on
                           the date such Stock Option is exercised or canceled.
                           To the extent that the consideration paid in any such
                           transaction described above consists all or in part
                           of securities or other non-cash consideration, the
                           value of such securities or other non-cash
                           consideration shall be determined in the sole
                           discretion of The Board.

7.       Term, Amendment and Termination.

         The Plan will terminate on December 17, 2006. Stock Options outstanding
         as of December 17, 2006 shall not be affected or impaired by the
         termination of The Plan.

         The Committee shall have authority to amend The Plan without the
         approval of the Company's stockholders to take into account changes in
         law and tax and accounting rules, including Rule 16b-3 and Section
         162(m) of The Code; provided that no amendment shall be made without
         the Optionee's consent which would impair the rights of an Optionee
         under a Stock Option theretofore granted without the Optionee's
         consent.

8.       Unfunded Status of Plan.

         It is presently intended that The Plan constitute an "unfunded" plan
         for incentive and deferred compensation. The Committee may authorize
         the creation of trusts or other arrangements to meet the obligations
         created under The Plan to deliver Stock or make payments; provided,
         however, that, unless The Committee otherwise determines, the existence
         of such trusts or other arrangements is consistent with the "unfunded"
         status of The Plan.

9.       General Provisions.

         a. The Committee may require each person purchasing shares pursuant to
         a Stock Option to represent to and agree with the Company in writing
         that such person is acquiring the shares without a view to the
         distribution thereof. The certificates for such shares may include any
         legend which The Committee deems appropriate to reflect any
         restrictions on transfer.

         Notwithstanding any other provision of The Plan or agreements made
         pursuant thereto, the Company shall not be required to issue or deliver
         any certificate or certificates for shares of Stock under The Plan
         prior to fulfillment of all of the following conditions:

                  (1) the listing or approval for listing

                                       21
<PAGE>   14
                  (2) any registration or other qualification

                  (3) the obtaining of any other consent, approval, or permit
                  from any state or federal governmental agency which The
                  Committee shall, in its absolute discretion after receiving
                  the advice of counsel, determine to be necessary or advisable.

         b. Nothing contained in The Plan shall prevent the Company or any of
         its Affiliates from adopting other or additional compensation
         arrangements for any Optionee.

         c. The adoption of The Plan shall not confer upon any Optionee any
         right to continued employment, nor shall it interfere in any way with
         the right of the Company or any of its Affiliates to terminate the
         employment of any Optionee with or without cause at any time whatsoever
         absent a written employment contract to the contrary.

         d. No later than the date as of which an amount first becomes
         includable in the gross income of the Optionee for federal income tax
         purposes with respect to any Stock Option under The Plan, and prior to
         the delivery of any shares of Stock to any Optionee, the Optionee shall
         pay to the Company, or make arrangements satisfactory to the Company
         regarding the payment of, any federal, state, local or foreign taxes of
         any kind required by law to be withheld by the Company with respect to
         such amount. In the discretion of The Committee, withholding
         obligations may be settled with Stock in an amount having a Fair Market
         Value not exceeding the minimum withholding tax payable by the Optionee
         with respect to the income recognized, including Stock that is subject
         to the Stock Option that gives rise to the withholding requirement. The
         obligations of the Company under The Plan shall be conditional on such
         payment or arrangements, and the Company and any of its Affiliates
         shall, to the extent permitted by law, have the right to deduct any
         such taxes from any payment otherwise due to the Optionee. The
         Committee shall establish such procedures as it deems appropriate,
         including the making of irrevocable elections, for the settlement of
         withholding obligations with Stock.

         e. In the case of a grant of a Stock Option to any employee of a
         Company Affiliate, the Company, may, if The Committee so directs, issue
         or transfer the shares of Stock covered by the Stock Option to the
         Affiliate, for such lawful consideration as The Committee may specify,
         upon the condition or understanding that the Affiliate will transfer
         the shares of Stock to that Optionee in accordance with the terms of
         the Stock Option specified by The Committee pursuant to the provisions
         of The Plan.

         f. The Plan and all Stock Options made and actions taken thereunder
         shall be governed by and construed in accordance with



                                       22
<PAGE>   15
         the laws of the State of California, without reference to principles of
         conflict of law.

10.      Effective Date of Plan.

         Subject to approval by the Stockholders of the Company on March 18,
         1997, The Plan shall be effective on December 17, 1996.

         Re:      ABM Industries Incorporated Registration Statement on Form
                  S-8/ Long-Term Senior Executive Stock Option Plan

Ladies and Gentlemen:

                  At your request, I am rendering this opinion in connection
with the proposed issuance pursuant to the ABM Industries Incorporated Long-Term
Senior Executive Stock Option Plan (the "Plan"), of up to 1,500,000 shares of
common stock, $0.01 par value ("Common Stock"), of ABM Industries Incorporated,
a Delaware corporation (the "Company").

                  I have examined instruments, documents, and records which I
deemed relevant and necessary for the basis of my opinion hereinafter expressed.
In such examination, I have assumed the following: (a) the authenticity of
original documents and the genuineness of all signatures; (b) the conformity to
the originals of all documents submitted to me as copies; and (c) the truth,
accuracy and completeness of the information, representations and warranties
contained in the records, documents, instruments and certificates I have
reviewed.

                  Based on such examination, I am of the opinion that the
1,500,000 shares of Common Stock to be issued by the Company pursuant to the
Plan are validly authorized shares of Common Stock and, when issued in
accordance with the provisions of the Plan, will be legally issued, fully paid
and nonassessable.

                  I hereby consent to the filing of this opinion as an exhibit
to this Registration Statement on Form S-8 and to the use of our name whenever
it appears in said Registration Statement. In giving such consent, I do not
consider that I am an "expert" within the meaning of such term as used in the
Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission issued thereunder, with respect to any part
of the Registration Statement, including this opinion as an exhibit or
otherwise.

                                                     Very truly yours,



                                                     /s/  Harry H. Kahn
