ITEM 1.  BUSINESS.

     ABM Industries Incorporated ("ABM") is the largest facility services
contractor listed on the New York Stock Exchange. With annual revenues exceeding
$1.6 billion and more than 57,000 employees, ABM and its subsidiaries (the
"Company") provide air conditioning, elevator, engineering, janitorial,
lighting, parking and security services to thousands of commercial, industrial
and institutional customers who outsource these services in hundreds of cities
across North America.

     ABM was reincorporated in Delaware on March 19, 1985, as the successor to a
business founded in California in 1909. The Corporate Headquarters of the
Company are located at 160 Pacific Avenue, Suite 222, San Francisco, California
94111, and its telephone number is 415/733-4000.

INDUSTRY SEGMENT INFORMATION

     The Company's operations are grouped into nine industry segments or
divisions (comprised of one or more subsidiaries of the Company). Referred to as
"ABM Industries Incorporated Family of Services", they are listed below by their
respective division name:

<TABLE>
<S>                           <C>
- - ABM Engineering Services    - Amtech Elevator Services
- - ABM Facility Services       - Amtech Lighting Services
- - ABM Janitorial Services     - CommAir Mechanical
- - American Commercial           Services
  Security                    - Easterday Janitorial
- - Ampco System Parking        Supply Company
</TABLE>

     Additional information relating to the Company's industry segments appears
in Note 14 of Notes to Consolidated Financial Statements contained in Item 8,
Financial Statements and Financial Statement Schedule. The business activities
of the Company's industry segments, as they existed at October 31, 1999, are
more fully described below.

          M ABM ENGINEERING SERVICES provides building owners and managers with
     on-site engineers to operate, maintain and repair electrical, energy
     management, mechanical, and plumbing systems utilizing computerized
     maintenance management systems (CMMS). This service is primarily for
     high-rise office buildings, but customers also include schools, warehouses,
     factories, shopping malls and universities. ABM Engineering Services
     operates in 25 states through seven regional offices, two of which are in
     California and one each in Chicago, Illinois; Denver, Colorado;
     Philadelphia, Pennsylvania; New York, New York; and Phoenix, Arizona. In
     1999, this Division earned ISO 9002 Certification, the first national
     engineering services provider of on-site operating engineers to earn this
     exclusive designation. ISO is a quality standard comprised of a rigorous
     set of guidelines and good business practices against which companies are
     rated through a comprehensive independent audit process that can take
     several years.

          M ABM FACILITY SERVICES provides customers with streamlined,
     centralized control and coordination of multiple facility service needs.
     This process is consistent with the greater competitive demands on
     corporate organizations to become more efficient in the business market
     today. By leveraging the core competencies of the Company's other
     affiliated divisions, this Division attempts to reduce overhead, such as
     redundant personnel, for its customers by providing multiple services under
     a single contract, with one contact and one invoice. Its National Service
     Center provides centralized dispatching, emergency services, accounting and
     related reports to financial institutions, high-tech companies, and other
     customers regardless of industry or size. ABM Facility Services is
     headquartered in San Francisco, where it also maintains its National
     Service Center.

          M ABM JANITORIAL SERVICES (also known as "American Building
     Maintenance") provides a wide range of basic janitorial services for a
     variety of structures and organizations, including office buildings,
     industrial plants, banks, department stores, theaters, warehouses,
     educational and health institutions and airport terminals. Services
     provided include floor cleaning and finishing, wall and window washing,
     furniture polishing, rug cleaning, dusting, as well as other building
     cleaning services. ABM Janitorial Services maintains 106 offices in 35
     states, the District of Columbia and one Canadian province, and operates
     under thousands of individually negotiated building maintenance contracts,
     the majority of which are obtained by competitive bidding. Generally,
     profit margins on maintenance contracts tend to be inversely proportional
     to the size of the contract. Although many of this Division's maintenance
     contracts are fixed-price agreements, others contain clauses under which
     the customer agrees to reimburse the full amount of wages, payroll taxes,
     insurance charges and

                                        3
<PAGE>   4

     other expenses plus a profit percentage. The majority of ABM Janitorial
     Services contracts are for one-year periods, contain automatic renewal
     clauses and are subject to termination by either party upon 30 to 90 days
     written notice.

          M AMERICAN COMMERCIAL SECURITY (also known as "ACS" and "ABM Security
     Services") provides security guards, electric monitoring of fire, life,
     safety, and access control devices, and security consulting services to a
     wide range of businesses in the major metropolitan areas of Phoenix,
     Arizona; San Francisco, San Diego and Los Angeles, California; Chicago,
     Illinois; New Orleans, Louisiana; Minneapolis, Minnesota; Portland, Oregon;
     Houston, Dallas, Fort Worth, Austin and San Antonio, Texas; Seattle,
     Washington; and Salt Lake City, Utah. Much like ABM Janitorial Services,
     the majority of this Division's contracts are for one-year periods, contain
     automatic renewal clauses and are subject to termination by either party
     upon 30 to 90 days written notice.

          M AMPCO SYSTEM PARKING (also known as "Ampco System Airport Parking"
     and "Ampco Express Airport Parking") operates approximately 1,500 parking
     lots and garages, which are either leased from or operated for third
     parties. The lease terms generally range from 5 to 20 years and usually
     contain provisions for renewal options. Leases which expire may continue on
     a month-to-month basis or are replaced by similar leases. Many leases
     contain provisions for contingent rentals based on revenues. Ampco System
     Parking currently operates in 24 states, including five of the 20 busiest
     international airports in the U.S.: Denver, Honolulu, Newark, Phoenix, and
     San Francisco. In conjunction with its on-airport parking services, this
     Division also operates off-airport parking facilities in Philadelphia,
     Houston, and Los Angeles, and parking shuttle bus service at thirteen
     locations.

          M AMTECH ELEVATOR SERVICES maintains, modernizes and repairs elevators
     and escalators in major metropolitan areas of California; Houston, Texas;
     Cincinnati, Ohio; Detroit, Michigan; Upper Marlboro, Maryland; Las Vegas,
     Nevada; Pennsauken, New Jersey; Atlanta, Georgia; Philadelphia,
     Pennsylvania; Phoenix, Arizona; Denver, Colorado; Chicago, Illinois; and
     Washington, D.C. Amtech Elevator Services maintains 17 offices and several
     parts warehouses, and operates a fleet of radio-equipped service vehicles.

          M AMTECH LIGHTING SERVICES (also known as "Sica Lighting & Electrical
     Services") provides relamping, fixture cleaning and periodic maintenance
     service to its customers. Amtech Lighting Services also repairs, services,
     designs and installs outdoor signage. This Division maintains 24 offices,
     eight of which are located in California; four of which are in Texas; and
     one office in each of the following states: Arizona, Florida, Georgia,
     Illinois, Maryland, Minnesota, Nevada, New Jersey, New Mexico, New York,
     Louisiana, and Oklahoma.

          M COMMAIR MECHANICAL SERVICES (also known as "CommAir Preferred
     Mechanical Services") installs, maintains, and repairs heating, ventilation
     and air conditioning equipment, performs chemical water treatment, and
     provides energy conservation services for commercial, industrial and
     institutional facilities. CommAir Mechanical Services maintains ten
     offices, nine of which are located in California, and one in Phoenix,
     Arizona.

          M EASTERDAY JANITORIAL SUPPLY markets janitorial supplies and
     equipment through six sales offices located in San Francisco, Los Angeles
     and Sacramento, California; Portland, Oregon; Reno, Nevada; and Houston,
     Texas. Easterday has also approved over 30 sub-distributors to serve ABM
     Janitorial Services and any customer in 26 other states and the District of
     Columbia. Aside from sales to ABM Janitorial Services, which, in 1999,
     accounted for approximately 29% of Easterday Janitorial Supply's total
     revenues, the principal customers for this Division are industrial plants,
     schools, commercial buildings, industrial organizations, transportation
     terminals, theaters, hotels, retail stores, restaurants, military
     establishments and janitorial service companies. Among the products sold
     are cleaning equipment, disinfectants, floor cleaners, floor finishes,
     glass cleaners, paper products and polishes. The products sold include many
     nationally advertised brands, which, in large part, are manufactured by
     others. This Division blends certain cleaning agents and floor finishes,
     which it sells under the Easterday trade name, and provides sanitation
     services to the food industry.

TRADEMARKS

     The Company believes that it owns or is licensed to use all corporate
names, trade names, trademarks, service marks, copyrights, patents and trade
secrets which are material to the Company's operations.

                                        4
<PAGE>   5

COMPETITION

     The Company believes that each aspect of its business is highly
competitive, and that such competition is based primarily on price and quality
of service. Many contracts are obtained through competitive bidding. The
Company's competitors include a large number of regional and local companies
located in major cities throughout the United States and Canada. While the
majority of the Company's competitors operate in a limited geographic area, the
operating divisions of a few large, diversified facility service companies
compete with the Company on a national basis.

SALES AND MARKETING

     The Company's sales and marketing efforts are conducted by its corporate,
division, region, branch and district offices. Sales, marketing, management and
operations personnel in each of these offices participate directly in selling
and servicing customers. The broad geographic scope of these offices enables the
Company to provide a full range of facility services through intercompany sales
referrals, multi-service "bundled" sales and national account sales. The Company
also has designated a nationwide group of "ABM Family of Services" executives to
market all of the Company's facility services capabilities.

     The Company has a broad customer base including airports, apartment
complexes, city centers, colleges and universities, financial institutions,
industrial plants, office buildings, retail stores, shopping centers and theme
parks. No customer accounted for more than 5% of its revenues during the fiscal
year ended October 31, 1999.

EMPLOYEES

     The Company employs over 57,000 persons, of whom the vast majority are
service employees who perform air conditioning, elevator, engineering,
janitorial, lighting, parking and security services. Approximately 24,400 of
these employees are covered under collective bargaining agreements. There are
about 3,300 employees with executive, managerial, supervisory, administrative,
professional, sales, marketing, clerical and other office assignments.

ENVIRONMENTAL MATTERS

     The discussion of the Company's environmental matters can be found in Item
7, Management's Discussion and Analysis of Financial Condition and Results of
Operations.

ITEM 2.  PROPERTIES.

     The Company has corporate, division, regional, branch, or district offices
in over 250 locations throughout the United States, and Canada. Twelve of these
facilities are owned by the Company and the remainder are leased. At October 31,
1999, the real estate owned by the Company had an aggregate net book value of
$3.2 million and was located in: Phoenix, Arizona; Fresno, California;
Jacksonville and Tampa, Florida; Elko, Nevada; Portland, Oregon; Houston and San
Antonio, Texas; and Kennewick, Seattle, Spokane and Tacoma, Washington.

     Rental payments under long and short-term lease agreements amounted to
$96.4 million for the fiscal year ended October 31, 1999. Of this amount, $72.0
million in rental expense was attributable to public parking lots and garages
that Ampco System Parking leases and operates. The remaining expense was for the
rental or lease of office space, computers, operating equipment and motor
vehicles.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
         CONDITION AND RESULTS
         OF OPERATIONS.

FINANCIAL CONDITION

     The following discussion should be read in conjunction with the
consolidated financial statements of the Company and the notes thereto contained
in Item 8. All information in the discussion and references to the years are
based on the Company's fiscal year that ends on October 31.

     Funds provided from operations and bank borrowings have historically been
the sources for meeting working capital requirements, financing capital
expenditures, acquisitions and paying cash dividends. Management believes that
funds from these sources will remain available and adequately serve the
Company's liquidity needs. The Company has an unsecured revolving credit
agreement with a syndicate of U.S. banks that provides a $150 million line of
credit expiring July 1, 2002. At the Company's option, the credit facility
provides interest at the prime rate or IBOR+.35%. As of October 31, 1999, the
total amount outstanding was approximately $90 million, which was comprised of
loans in the amount of $26 million and standby letters of credit of $64 million.
This agreement requires the Company to meet certain financial ratios, places
some limitations on outside borrowing and prohibits declaring or paying cash
dividends exceeding 50% of the Company's net income for any fiscal year. In
addition, the Company has a loan agreement with a major U.S. bank with a balance
of $3,386,000 at October 31, 1999. This loan bears interest at a fixed rate of
6.78% with annual payments of principal, in varying amounts, and interest due
each February 15 through 2003. The Company's effective interest rate for all
long-term debt bank borrowings for the year ended October 31, 1999 was 6.8%.

     Operating activities generated cash flows in 1997, 1998 and 1999 of $27.7
million, $32.1 million and $35.3 million, respectively. Cash paid for
acquisitions during the fiscal years ended October 31, 1997, 1998 and 1999,
including payments pursuant to contractual arrangements involved in prior
acquisitions, were approximately $28.6 million, $10.0 million and $11.0 million,
respectively. Capital expenditures during fiscal years 1997, 1998 and 1999 were
$13.3 million, $11.7 million and $19.5 million, respectively. Cash dividends
paid to stockholders of common and redeemable preferred stock and amounts used
to repurchase common stock were approximately $8.6 million in 1997, $10.7
million in 1998 and $18.5 million in 1999. At October 31, 1998, working capital
was $165.8 million as compared to $184.3 million at October 31, 1999.

EFFECT OF INFLATION

     The low rates of inflation experienced in recent years have had no material
impact on the financial statements of the Company. The Company attempts to
recover inflationary costs by increasing sales prices to the extent permitted by
contracts and competition.

ENVIRONMENTAL MATTERS

     The nature of the Company's operations, primarily services, would not
ordinarily involve it in environmental contamination. However, the Company's
operations are subject to various federal, state and/or local laws regulating
the discharge of materials into the environment or otherwise relating to the
protection of the environment, such as discharge into soil, water and air, and
the generation, handling, storage, transportation and disposal of waste and
hazardous substances. These laws generally have the effect of increasing costs
and potential liabilities associated with the conduct of the Company's
operations, although historically they have not had a material adverse effect on
the Company's financial position, cash flows or its results of operations.

     The Company is currently involved in four proceedings relating to
environmental matters: one involving alleged potential soil and groundwater
contamination at a Company facility in Florida; one involving alleged potential
soil contamination at a former Company facility in Arizona; one involving
alleged potential soil and groundwater contamination of a parking garage
previously operated by the Company in Washington; and, one involving alleged
potential soil and groundwater contamination at a former dry-cleaning facility
leased by the Company in Nevada. While it is difficult to predict the ultimate
outcome of these matters, based on information currently available, management
believes that none of these matters, individually or in the aggregate, are
reasonably likely to have a material adverse effect on the Company's financial
position, cash flows, or its results of operations.

YEAR 2000 ISSUE

     The Year 2000 Issue is the result of computer programs being written and
embedded chips being designed that used two digits rather than four digits to
define the applicable year. As a result, there

                                        9
<PAGE>   10

existed a potential that existing computer programs and hardware would be unable
to accurately process dates beyond the year 1999. In mid-1997, the Company
established a dedicated project team that developed a detailed plan for making
the Company Year 2000 compliant. The plan encompassed both information
technology-related systems, such as the Company's accounting software and non-IT
related systems, as well as the impact to the Company due to the non-compliance
of major vendors or customers. The Company completed its plan with respect to
hardware and software prior to the end of 1999. It also surveyed significant
vendors with respect to their Year 2000 compliance and where deemed appropriate
identified alternate suppliers. The Company also established contingency plans.
The aggregate expense of these efforts was approximately $3.0 million. As of
January 26, 2000, the Company has not experienced any significant Y2K failures.
Several minor issues were reported to the Y2K project team, but did not affect
business and have been corrected. There can be no certainty that failures or
problems related to Year 2000 might not develop in the future, but management
believes no such failure or problem is reasonably likely to materially disrupt
the Company's business.

ACQUISITIONS

     The operating results of businesses acquired have been included in the
accompanying consolidated financial statements from their respective dates of
acquisition and are fully discussed in Note 12 to the Consolidated Financial
Statements. Acquisitions made during the three fiscal years ended October 31,
1999, contributed approximately $235 million to fiscal 1999 revenues, including
the August 1997 acquisition in New York which contributed $153 million of these
revenues.

INTERNAL INVESTIGATION

     During fiscal year 1999, the Audit Committee of the Board of Directors
conducted an investigation of alleged questionable payments and related
accounting practices in connection with janitorial service contracts
representing less than 5% of the Company's consolidated revenues. The Company
does not believe that the matter investigated will have any material impact on
its financial condition, cash flow or results of operations. However, in an
abundance of caution, the Company has referred the matter to appropriate
government authorities.

RESULTS OF OPERATIONS

COMPARISON OF 1999 TO 1998

     The Company reported record revenues and earnings for 1999. Revenues and
other income (hereinafter called "revenues") were $1.6 billion in 1999, up $128
million or 9%, from $1.5 billion reported in 1998. The increase in revenues in
1999 over 1998 was attributable to new business and price increases as well as
acquisitions made during the prior years. Acquisitions during 1999 accounted for
approximately $11 million, or approximately 9% of the total revenue increase of
$128 million for 1999.

     As a percentage of revenues, operating expenses and cost of goods sold was
86.7% for 1999, compared to 86.5% in 1998. Consequently, as a percentage of
revenues, the Company's gross profit (revenues minus operating expenses and cost
of goods sold) of 13.3% in 1999 was slightly lower than the gross profit of
13.5% in 1998. The decrease in gross profit as a percentage of revenues was
mostly due to higher labor and related costs, particularly workers' compensation
insurance and continued competitive pressure to maintain or lower prices. The
Company anticipates such increased costs may be gradually recovered through
future price increases. For the next fiscal year, management has committed to
negotiating with its customers appropriate price increases.

     Selling, general and administrative expenses increased 3.2% for 1999
compared to 1998. However, as a percentage of revenues, selling, general and
administrative expenses decreased from 9.5% for 1998, to 9.0% for 1999,
primarily due to certain costs (such as health insurance and legal fees) that do
not increase at the same rate as sales. The dollar increase in selling, general
and administrative expenses is primarily due to salaries and expenses associated
with acquisitions including the amortization of goodwill.

     Interest expense was $2.0 million in 1999 compared to $3.5 million for
1998, a decrease of $1.5 million. This decrease was primarily due to lower
weighted average borrowings.

     The income before income taxes (pre-tax income) for 1999 was $67.2 million
compared to $57.5 million, an increase of 17% over 1998. The growth in pre-tax
income outpaced the revenue growth for 1999 primarily due to the reduction (as a
percentage of revenues) of selling, general and administrative expenses.

                                       10
<PAGE>   11

     The estimated effective income tax rate for 1999 and 1998 was 41.0%.

     Net income for 1999 was $39.7 million, an increase of 17%, compared to net
income of $33.9 million in 1998. Diluted net income per common share rose 15% to
$1.65 for 1999 compared to $1.44 for the same period in 1998. The percentage
increase in diluted net income per share was less than the increase in net
income due to the 3% increase in number of diluted shares outstanding that
primarily resulted from stock purchased by employees under the Company's
Employee Stock Purchase Plan as well as stock options exercised. On September
22, 1999 the Company announced a stock repurchase program for up to one million
outstanding shares. As of October 31, 1999, 220,000 shares had been reacquired.
Earnings per share calculations also include the effect of a preferred stock
dividend deduction of $512,000 in both 1999 and 1998.

     The Company is organized into nine separate operating divisions as defined
under Statement of Financial Accounting Standards (SFAS) No. 131, "Disclosures
about Segments of an Enterprise and Related Information". However, only the ABM
Janitorial, Amtech Elevator, ABM Engineering, Amtech Lighting, and Ampco System
Parking Divisions are reportable using the criteria under SFAS 131. The results
of operations from these five reportable operating divisions for 1999 as
compared to 1998 are more fully described below:

     The ABM Janitorial Services Division reported revenues for 1999 of $933.7
million, an increase of approximately $74.2 million, or 9%, over 1998. This is
the Company's largest Division and accounted for approximately 57% of the
Company's consolidated revenues in 1999. ABM Janitorial Services revenues
increased as a result of new business, particularly in the Gulf Central,
Mid-Atlantic and Southwest regions. Revenues generated from acquisitions during
the prior year contributed about $8.7 million of the 1999 increase while the
current year acquisitions added $9.1 million. ABM Janitorial Services' operating
profits increased 11% in 1999 to $49.5 million when compared to 1998. This
profit increase was due primarily to the increase in revenues, reduced legal
fees and slightly lower labor and labor related costs.

     Revenues for Amtech Elevator Services were $96.6 million, up by 8% for 1999
over 1998, largely due to an increased customer base in the maintenance and
repair sector. The Amtech Elevator Division reported a 3% increase in operating
profits in 1999 to $6.7 million compared to 1998. The smaller increase in
operating profits can be attributed primarily to the inability of the Division
to pass on increased labor and insurance costs.

     The ABM Engineering Services Division increased revenues by 13% to $153.9
million and its operating profits increased 4% to $8.4 million for 1999 compared
to 1998. The large revenue increase was due primarily to new business in the
Midwest, Arizona, and Southern California regions. The smaller percentage
increase in operating profits is due to lower margins on contracts particularly
in the New York and Philadelphia regions and pressure from competition to reduce
fees.

     Amtech Lighting Services reported a 9% revenue increase to $95.8 million
due to increased business in the Atlanta, Chicago, New Orleans, New York, and
Oakland markets. Operating profits increased by 8% to $7.5 million during 1999
compared to the prior year primarily due to the increased sales.

     Ampco System Parking increased revenues to $162.4 million or 5% over 1999,
while its operating profits increased 22% to $8.5 million during 1999 compared
to 1998. The increase in revenues was mostly due to growth in its California
region. The operating profit increase was due for the most part to the
conversion from leased lots to management contracts, which have higher margins,
as well as improved profits related to off-airport parking operations.

COMPARISON OF 1998 TO 1997

     Revenues were $1.5 billion in 1998, up $249 million or 20%, from $1.3
billion reported in 1997. The 20% increase in revenues in 1998 over 1997 was
attributable to 1997 acquisitions, particularly large acquisitions in New York
of janitorial, engineering and lighting businesses, as well as sales and price
increases. Acquisitions made during 1998 accounted for approximately $6 million,
or approximately 2.4% of the total revenue increase of $249 million for 1998.

     As a percentage of revenues, operating expenses and cost of goods sold was
86.5% for 1998, compared to 85.9% in 1997. Consequently, the Company's gross
profit as a percentage of revenues of 13.5% in 1998 was lower than the gross
profit of 14.1% in 1997. The gross profit percentage declined mostly due to
higher labor and related costs and continued competitive pressure to lower
prices.

     Selling, general and administrative expenses for 1998 were $142.4 million
compared to $126.8 million in 1997. As a percentage of revenues, selling,
general and administrative expenses decreased from 10.1% for 1997, to 9.5% for
1998, primarily as a result of
                                       11
<PAGE>   12

certain costs not increasing at the same rate as sales. The dollar increase in
selling, general and administrative expenses of $15.6 million is primarily due
to expenses related to growth and to a lesser extent expenses associated with
acquisitions including the amortization of goodwill.

     Interest expense was $3.5 million in 1998 compared to $2.7 million for
1997, an increase of $790,000. This increase was primarily due to higher
weighted average borrowings during 1998, which were needed to fund acquisitions
and working capital.

     The income before income taxes (pre-tax income) for 1998 was $57.5 million
compared to $47.0 million, an increase of 22% over 1997. The growth in pre-tax
income outpaced the revenue growth for 1998 primarily due to lower insurance
costs as a percent of revenues.

     The estimated effective income tax rate for 1998 was 41.0%, compared to
42.0% in 1997. The lower tax rate was due for the most part to an increase in
various federal and state tax credits.

     Net income for 1998 was $33.9 million, an increase of 25%, compared to net
income of $27.2 million in 1997. Diluted net income per common share rose 18% to
$1.44 for 1998 compared to $1.22 for the same period in 1997. The increase in
diluted net income per share was not proportional to the increase in net income
due to the 6% increase in number of diluted shares outstanding primarily a
result of purchases made by employees under the Company's Employee Stock
Purchase Plan. Earnings per share calculations also include the effect of a
preferred stock dividend deduction of $512,000 in both 1998 and 1997.

     The results of operations from the Company's five reportable operating
divisions for 1998 as compared to 1997 are more fully described below:

     Revenues of the ABM Janitorial Services Division increased by 25% during
1998 to $859.4 million, as compared to 1997, as a result of several acquisitions
made during 1997, particularly in the Northeast and the Southwest regions.
Revenues generated from those acquisitions during 1997 contributed $142 million
of the 1998 increase. Operating profits increased to $44.6 million in 1998, or
36%, when compared to 1997. This profit increase was due primarily to the
increase in revenues and lower labor and labor related costs.

     Revenues for the Amtech Elevator Services Division were $89.3 million, up
by 8% for 1998 over 1997, largely due to an increased customer base in the
maintenance and repair sector. The Amtech Elevator Division reported operating
profits of $6.5 million in 1998, a 39% increase compared to 1997. This increase
in operating profits can be attributed primarily to a higher profit margin on
service contracts and a substantial reduction of insurance costs.

     The ABM Engineering Services Division's revenues increased by 45% to $136.8
million and its operating profits increased 9% to $8.0 million for 1998 compared
to 1997. The revenue increase was due primarily to an acquisition in New York in
August 1997 and new business in the Midwest and West Central regions. The
smaller percentage increase in operating profits is due to lower margins
particularly on contracts purchased through the New York acquisition, increased
insurance costs and pressure from competition to reduce fees.

     Amtech Lighting Services reported a 10% revenue increase to $88.2 million
due to increased revenues in the Northeast and Dallas markets as well as from a
small acquisition in the Midwest. Operating profits increased by 11% to $6.9
million during 1998 compared to the prior year primarily due to the increased
sales.

     The Ampco System Parking Division's revenues increased by 7% to $154.1
million, while its profits increased 10% to $7.0 million during 1998 compared to
1997. The increase in revenues was mostly due to growth in its national airport
business and its Texas region. The operating profit increase was due for the
most part to lower payroll tax expense and the increased sales.

SAFE HARBOR STATEMENT

     Cautionary Safe Harbor Disclosure for Forward Looking Statements under the
Private Securities Litigation Reform Act of 1995: Because of the factors set
forth below, as well as other variables affecting the Company's operating
results, past financial performance, should not be considered a reliable
indicator of future performance, and investors should not use historical trends
to anticipate results or trends in future periods. The statements contained
herein which are not historical facts are forward-looking statements that are
subject to meaningful risks and uncertainties, including but not limited to: (1)
significant decreases in commercial real estate occupancy, resulting in reduced
demand and prices for building maintenance and other facility services in the
Company's major markets, (2) loss or bankruptcy of one or more of the Company's
major customers, which could adversely affect the Company's ability to collect
its accounts receivable or recover its deferred costs,

                                       12
<PAGE>   13

(3) major collective bargaining issues that may cause loss of revenues or cost
increases that non-union companies can use to their advantage in gaining market
share, (4) significant shortfalls in adding additional customers in existing and
new territories and markets, (5) a protracted slowdown in the Company's
acquisition program, (6) legislation or other governmental action that severely
impacts one or more of the Company's lines of business, such as price controls
that could restrict price increases, or the unrecovered cost of any universal
employer-paid health insurance, as well as government investigations that
adversely affect the Company, (7) reduction or revocation of the Company's line
of credit, which would increase interest expense or the cost of capital, (8)
cancellation or nonrenewal of the Company's primary insurance policies, as many
customers contract out services based on the contractor's ability to provide
adequate insurance coverage and limits, (9) catastrophic uninsured or
underinsured claims against the Company, the inability of the Company's
insurance carriers to pay otherwise insured claims, or inadequacy in the
Company's reserve for self-insured claims, (10) resignation, termination, death
or disability of one or more of the Company's key executives, which could
adversely affect customer retention and day-to-day management of the Company,
(11) inability to employ entry level personnel due to labor shortages, and (12)
other material factors that are disclosed from time to time in the Company's
public filings with the United States Securities and Exchange Commission, such
as reports on Forms 8-K, 10-K and 10-Q.

ITEM 7A.  QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK.

     The Company does not issue or invest in financial instruments or their
derivatives for trading or speculative purposes. The operations of the Company
are conducted primarily in the United States, and, as such, are not subject to
material foreign currency exchange rate risk. Although the Company has
outstanding debt and related interest expense, market risk in interest rate
exposure in the United States is currently not material.

ABM Industries Incorporated and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     PRINCIPLES OF CONSOLIDATION: The consolidated financial statements include
the accounts of ABM Industries Incorporated and its subsidiaries ("the
Company"). All material intercompany transactions and balances have been
eliminated. Certain reclassifications of prior year amounts have been made to
conform with the current year presentation.

     USE OF ESTIMATES: The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the consolidated
financial statements and related notes to financial statements. Changes in such
estimates may affect amounts reported in future periods.

     ACCOUNTS RECEIVABLE: The Company's accounts receivable are principally
trade receivables arising from services provided to its customers and are
generally due and payable on terms varying from the receipt of invoice to net
thirty days. The Company does not believe that it has any material exposure due
to either industry or regional concentrations of credit risk.

     INVENTORIES: Inventories are valued at amounts approximating the lower of
cost (first-in, first-out basis) or market.

     PROPERTY, PLANT AND EQUIPMENT: Property, plant and equipment are stated at
cost less accumulated depreciation and amortization. At the time property, plant
and equipment is retired or otherwise disposed of, the cost and accumulated
depreciation are removed from the accounts and any resulting gain or loss is
reflected in income. Maintenance and repairs are charged against income.

     Depreciation and amortization are calculated principally on the
straight-line method. Lives used in computing depreciation for transportation
equipment average 3 to 5 years and 2 to 20 years for machinery and other
equipment. Buildings are depreciated over periods of 20 to 40 years. Leasehold
improvements are amortized over the shorter of the terms of the respective
leases, or the assets' useful lives.

     The Company is implementing an enterprise-wide information system. External
direct costs of materials and services and payroll-related costs of employees
working solely on the development of the system are capitalized. In addition, in
1999 related interest costs of approximately $135,000 were capitalized.
Capitalized costs of the project will be amortized over a period of five years
beginning when the system is placed in service. Training costs are expensed as
incurred.

     INTANGIBLE ASSETS: Intangible assets consist of goodwill in the amount of
$152,477,000 and other intangible assets in the amount of $2,403,000, net of
accumulated amortization of $49,297,000. Goodwill, which represents the excess
of cost over fair value of tangible assets of businesses acquired, is amortized
on a straight-line basis over periods not exceeding 40 years. It is the
Company's policy to carry goodwill applicable to acquisitions prior to 1971 of
$1,450,000 at cost until such time as there may be evidence of diminution in
value.

     IMPAIRMENT OF LONG-LIVED ASSETS: The Company annually reviews its
long-lived assets, including goodwill. Impairment is evaluated on the basis of
whether the asset is fully recoverable from projected, undiscounted net cash
flows of the related business unit, in accordance with Statement of Financial
Accounting Standards No. 121. Impairment is recognized in operating results when
a permanent diminution in value is believed to have occurred. The Company
measures impairment as the excess of any unamortized goodwill over the estimated
future discounted cash flows over the remaining life of the asset. During the
year ended October 31, 1997, the Company's ABM Janitorial Division wrote off
$2,700,000 of goodwill that was deemed to be permanently impaired.

     INCOME TAXES: Income tax expense is based on reported results of operations
before income taxes. In accordance with Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes", deferred income taxes reflect
the impact of temporary differences between the amount of assets and liabilities
recognized for financial reporting purposes and such amounts recognized for tax
purposes. These deferred taxes are measured using enacted tax rates expected to
apply to taxable income in the years in which those temporary differences are
expected to be recovered or settled.

     REVENUE RECOGNITION: Revenues are generally recorded at the time services
are performed or when products are shipped.

                                       17

     NET INCOME PER COMMON SHARE: The company has reported its earnings in
accordance with Statement of Financial Accounting Standards No. 128, "Earnings
per Share". Basic net income per common share, after the reduction for preferred
stock dividends, is based on the weighted average number of shares actually
outstanding during the period. Diluted net income per common share, after the
reduction for preferred stock dividends, is based on the weighted average number
of shares outstanding during the period, including common stock equivalents.
Diluted net income per common share is consistent with the Company's former
presentation of primary net income per common share. The calculation of these
amounts is as follows:

     For the purposes of computing diluted net income per common share, weighted
average common share equivalents do not include stock options with an exercise
price that exceeds the average fair market value of the Company's common stock
for the period. On October 31, 1999, options to purchase approximately 1,268,000
shares of common stock at a weighted average exercise price of $31.09 were
outstanding, but were excluded from the computation because the options'
exercise price was greater than the average market price of the common shares.
At October 31, 1998, 938,000 shares of common stock at a weighted average
exercise price of $31.78 were outstanding, but were excluded from the
computation because the options' exercise price was greater than the average
market price of the common shares.
     CASH AND CASH EQUIVALENTS: The Company considers all highly liquid
instruments with original maturities of three months or less to be cash and cash
equivalents.
     STOCK-BASED COMPENSATION: The Company accounts for its stock-based awards
using the intrinsic value method in accordance with Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees".

     COMPREHENSIVE INCOME: In 1997, the Financial Accounting Standards Board
issued Statement of Financial Accounting Standards (SFAS) No. 130, "Reporting
Comprehensive Income". The Company adopted SFAS 130 during fiscal 1999. The new
rules established standards for the reporting of comprehensive income and its
components in financial statements. Comprehensive income consists of net income
and other related gains and losses affecting shareholder's equity that, under
generally accepted accounting principles, are excluded from net income. For the
Company, such comprehensive income items consist of foreign currency gains and
losses, the tax effect of such was insignificant. The adoption of SFAS 130
affected the presentation in the accompanying consolidated balance sheets and
consolidated statements of stockholders' equity and comprehensive income. Prior
year financial statements have been reclassified to conform to the new
requirements.

2. INSURANCE

     Certain insurable risks such as general liability, property damage and
workers' compensation are self-insured by the Company. However, the Company has
umbrella insurance coverage for certain risk exposures subject to specified
limits. Accruals for claims under the Company's self-insurance program are
recorded on a claim-incurred basis. Under this program, the estimated liability
for claims incurred but unpaid at October 31, 1998 and 1999 was $79,165,000 and
$83,665,000, respectively. In connection with certain self-insurance agreements,
the Company has standby letters of credit at October 31, 1999 supporting the
estimated unpaid liability in the amounts of $62,557,000.

5. LONG-TERM DEBT AND CREDIT AGREEMENT

     The Company has a $150 million syndicated line of credit expiring July 1,
2002. The unsecured revolving credit facility provides, at the Company's option,
interest at the prime rate or IBOR+.35%. The facility calls for a commitment fee
payable quarterly, in arrears, of .12% based on the average, daily, unused
portion. For purposes of this calculation, irrevocable standby letters of credit
issued in conjunction with the Company's self-insurance program plus cash
borrowings are considered to be outstanding amounts. As of October 31, 1999, the
total outstanding amount under this facility was $90 million comprised of $26
million in loans and $64 million in standby letters of credit. The interest
rates at October 31, 1999 on loans outstanding under this agreement ranged from
5.79% to 8.25%. The Company is required, under this agreement to maintain
financial ratios and places certain limitations on dividend payments. The
Company is prohibited from paying cash dividends exceeding 50% of its net income
for any fiscal year.

     The Company has a loan agreement with a major U.S. bank with a balance of
$3,386,000 at October 31, 1999. This loan bears interest at a fixed rate of
6.78% with annual payments of principal, in varying amounts, and interest due
each February 15 through 2003.

     The long-term debt of $29,801,000 matures in the years ending October 31 as
follows: $898,000 in 2000; $902,000 in 2001; $26,916,000 in 2002, $990,000 in
2003, $47,000 in 2004, and $48,000 in subsequent years.

6. EMPLOYEE BENEFIT PLANS

(A) RETIREMENT AGREEMENTS

     The Company has unfunded retirement agreements for approximately 44 current
and former directors and senior executives, many of which are fully vested. The
agreements provide for annual benefits for ten years commencing at the later of
the respective retirement dates of those executives or age 65. The benefits are
accrued over the period these directors and senior executives are expected to be
employed by the Company. During 1997, 1998 and 1999, amounts accrued under these
agreements were $629,000, $513,000 and $674,000, respectively. Payments were
made in 1997, 1998 and 1999 in the amounts of $124,000, $207,000 and $231,000,
respectively.

(B) 401(K) AND PROFIT SHARING PLAN

     The Company has a profit sharing and 401(k) plan covering certain qualified
employees, which includes employer participation in accordance with the
provisions of Section 401(k) of the Internal Revenue Code. The plan allows
participants to make pretax contributions and the Company matches certain
percentages of employee contributions depending on the participant's length of
service. The profit sharing portion of the plan is discretionary and
noncontributory. All amounts contributed to the plan are deposited into a trust
fund administered by independent trustees.

     The Company provided for profit sharing contributions of $1,336,000,
$1,534,000 and $1,643,000 for 1997, 1998 and 1999, respectively. The Company's
matching 401(k) contributions required by the 401(k) plan for 1997, 1998 and
1999 were approximately $873,000, $1,066,000 and $1,210,000, respectively.

(C) SERVICE AWARD BENEFIT PLAN

     In 1989 the Company adopted an unfunded service award benefit plan, with a
retroactive vesting period of five years. This plan is a "severance pay plan" as
defined by the Employee Retirement Income Security Act (ERISA) and covers
certain qualified employees. The plan provides participants, upon termination,
with a guaranteed seven days pay for each year of employment subsequent to
November 1, 1989. The Company, at its discretion, may also award additional days
each year.
     Net cost of the plan is comprised of:

     Contingent rentals are applicable to leases of parking lots and garages and

8. COMMITMENTS AND CONTINGENCIES

     The Company and certain of its subsidiaries have been named defendants in
certain litigation arising in the ordinary course of business. In the opinion of
management, based on advice of legal counsel, such matters should have no
material effect on the Company's consolidated financial statements taken as a
whole.

9. REDEEMABLE CUMULATIVE PREFERRED STOCK

     On June 23, 1993, the Company authorized 6,400 shares of preferred stock
having a par value of $0.01 per share. These shares designated as Series B 8%
Senior Redeemable Cumulative Preferred Stock (Series B Preferred Stock) shall be
entitled to one vote per share on all matters upon which common stockholders are
entitled to vote and have a redemption price of $1,000 per share, together with
accrued and unpaid dividends thereon. Redemption of the Series B Preferred Stock
is at the option of the holders for any or all of the outstanding shares after
September 1, 1998 or at the option of the Company after September 1, 2002. The
total redemption value of the shares outstanding at October 31, 1998 and

                                       20
<PAGE>   21

1999 in an amount of $6,400,000 is classified on the Company's balance sheet as
redeemable cumulative preferred stock. In the event of any liquidation,
dissolution or winding up of the affairs of the Company, holders of the Series B
Preferred Stock shall be paid the redemption price plus all accrued dividends to
the date of liquidation, dissolution or winding up of affairs before any payment
to other stockholders.

     On September 1, 1993, the Company issued 6,400 shares of its Series B
Preferred Stock in conjunction with the acquisition of System Parking. The
acquisition agreement provided that one-half, or 3,200 shares, of the Series B
Preferred Stock be placed in escrow and will be released upon certain earnout
requirements. As of October 31, 1999, none of these shares have been released.

     Dividends of $128,000 are due and payable each quarter and are deducted
from net income in determining net income per common share.

10. CAPITAL STOCK

     In March 1999, the stockholders approved an amendment to the Company's
Certificate of Incorporation to increase the number of shares of common stock,
par value $.01 per share, authorized for issue from 28,000,000 to 100,000,000.

     The Company is also authorized to issue 500,000 shares of preferred stock,
of which 50,000 shares have been designated as Series A Junior Participating
Preferred Stock of $.01 par value. None of these preferred shares have been
issued.

     In March 1998, the Company's Board of Directors adopted a stockholder
rights plan to replace an existing rights plan that expired on April 22, 1998.
The new plan provides for a dividend distribution of one preferred stock
purchase right (a "Right") for each outstanding share of common stock,
distributed to stockholders of record on April 22, 1998. The Rights will be
exercisable only if a person or group acquires 20% or more of the Company's
common stock (an "Acquiring Person") or announces a tender offer for 20% or more
of the common stock. Each Right will entitle stockholders to buy one-thousandth
of a share of newly created Participating Preferred Stock, par value $.01 per
share, of the Company at an initial exercise price of $175 per Right, subject to
adjustment from time to time. However, if any person becomes an Acquiring
Person, each Right will then entitle its holder (other than the Acquiring
Person) to purchase at the exercise price common stock (or, in certain
circumstances, Participating Preferred Stock) of the Company having a market
value at that time of twice the Right's exercise price. These Rightsholders
would also be entitled to purchase an equivalent number of shares at the
exercise price if the Acquiring Person were to control the Company's Board of
Directors and cause the Company to enter into certain mergers or other
transactions. In addition, if an Acquiring Person acquired between 20% and 50%
of the Company's voting stock, the Company's Board of Directors may, at its
option, exchange one share of the Company's common stock for each Right held
(other than Rights held by the Acquiring Person). Rights held by the Acquiring
Person will become void. The Rights Plan excludes from its operation The
Theodore Rosenberg Trust and The Sydney J. Rosenberg Trust, and certain related
persons, and, as a result, their holdings will not cause the Rights to become
exercisable or nonredeemable or trigger the other features of the Rights. The
Rights will expire on April 22, 2008, unless earlier redeemed by the Board at
$0.01 per Right.

     As discussed in Note 1, the Company continues to account for its
stock-based awards using the intrinsic value method in accordance with
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees", and its related interpretations. Accordingly, no compensation
expense has been recognized in the financial statements for employee stock
awards.

     Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock-Based Compensation", requires the disclosure of pro forma net earnings and
earnings per share had the Company adopted the fair value method as of the
beginning of fiscal 1996. Under SFAS 123, the fair value of stock-based awards
to employees is calculated through the use of option pricing models. The use of
these models requires subjective assumptions, including future stock price
volatility and expected time to exercise, which can have a significant effect on
the calculated values. The Company's calculations were made using the
Black-Scholes option pricing model with the following weighted average
assumptions: expected life 9.8 years, 11.4 years, and 11.9 years from the date
of grant in fiscal 1997, 1998, and 1999, respectively; expected stock price
volatility of 19.5%, 25.3%, and 26.2%, respectively; expected dividend yields of
2.6%, 1.5%, and 1.9%, and risk free interest rates of 6.5%, 6.0%, and 5.0% in
fiscal 1997, 1998, and 1999, respectively.

     The Company's calculations are based on a single option valuation approach
and forfeitures are

                                       21
<PAGE>   22

recognized as they occur. If the computed fair values of the fiscal awards had
been amortized to expense over the vesting period of the awards, pro forma net
earnings would have been $24,376,000 ($1.09 per share) for fiscal 1997,
$27,496,000 ($1.17 per share) for fiscal 1998, and $35,409,000 ($1.47 per share)
for fiscal 1999. The impact of outstanding stock options granted prior to fiscal
1996 has been excluded from the pro forma calculation; accordingly, the fiscal
1997, 1998, and 1999 pro forma adjustments are not indicative of future period
pro forma adjustments, when the calculation will apply to all future applicable
stock grants.

     Although most of the options granted under the "Price-Vested" Performance
Stock Option Plan adopted in fiscal 1996 were granted in fiscal 1997, the
recognition of expense in the SFAS 123 footnote for this Plan increased from
$724,296 in fiscal 1997 to $5,879,059 in fiscal 1998. This accounts for the
majority of the increase in the total recognition from all plans from $4,682,235
in fiscal 1997 to $10,513,464 in fiscal 1998. This large increase results from
the requirements contained in SFAS 123. The options from this Plan were granted
with a ten-year term. If, during the first four years, the stock price achieved
and maintained a set price for ten out of thirty consecutive trading days, the
options associated with the price would vest. The prices established were $25,
$30, $35 and $40, with 25% of the options vesting at each price point. If, at
the end of four years, any of the stock price performance targets were not
achieved, then the remaining options would vest at the end of eight years from
the date the options were granted. SFAS 123 requires that the projected value of
the options be determined on the grant date and recognized over the period in
which the options are earned (the vesting period). For these options, the
projected value of the options was determined and that value was to be
recognized over the eight-year vesting period unless vesting occurred at an
earlier date. In fiscal 1998 ABM stock achieved and maintained for the requisite
ten-day period, the first three price targets. As a result, 75% of the options
are now vested, and the projected value of that 75% less the amount recognized
in fiscal 1997 for those options is recognized in this year's footnote. Of the
remaining 25% of the originally granted options yet to be vested, one-eighth was
recognized in each of the last three years. The remaining amount will be
recognized over the next five years unless sooner vested by the stock achieving
a price of $40 per share and maintaining that price for ten out of 30
consecutive trading days.

     "Time-Vested" Incentive Stock Option Plan adopted in 1987, as amended

     In 1987, the Company adopted a stock option plan under which 1,200,000
shares were reserved for grant until December 31, 1996. In March 1994, this plan
was amended to reserve an additional 1,000,000 shares. In March 1996, the plan
was amended again to reserve another 2,000,000 shares. Options which terminate
without being exercised may be reissued. At October 31, 1999, 1,017,210 shares
remained available for grant.

     Transactions under this plan are summarized as follows:

     "Price-Vested" Performance Stock Option Plan adopted in 1996

     In December 1996, the Company adopted a stock option plan under which
1,500,000 shares have been reserved. The options expire 10 years after the date
of grant and any options which terminate without being exercised may be
reissued. Each option will have a pre-defined vesting price which provides for
accelerated vesting if the fair market value of the Company's common stock is
equal to or greater than the pre-defined vesting price for 10 trading days in
any period of 30 consecutive trading days. Vested options will become
exercisable only after the first anniversary of its grant date. Any option that
has not

     vested prior to the fourth anniversary of its grant date will vest on the
eighth anniversary of its grant date. At October 31, 1999, 310,000 shares
remained available for grant.

     "Age-Vested" Career Stock Option Plan
       adopted in 1984, as amended

     In 1984, the Company adopted a stock option plan whereby 680,000 shares
were reserved for grant. In March of 1996, another 1,000,000 shares were
reserved for grant under the plan. As amended December 20, 1994, options which
have been granted at fair market value are 50% exercisable when the option
holders reach their 61st birthday and the remaining 50% will vest on their 64th
birthday. To the extent vested, the options may be exercised at any time prior
to one year after termination of employment. Options which terminate without
being exercised may be reissued. At October 31, 1999, 434,000 shares remained
available for grant.

     Transactions under this plan are summarized as follows:

     Employee Stock Purchase Plan
       adopted in 1985, as amended

     In 1985, the Company adopted an employee stock purchase plan under which
sale of 5 million shares of its common stock has been authorized. In March of
1996, the sale of an additional 1,200,000 shares were authorized, and again in
March of 1999, 1,200,000 additional shares were authorized under this plan. The
purchase price of the shares under the plan is the lesser of 85% of the fair
market value at the commencement of each plan year or 85% of the fair market
value on the date of purchase. Employees may designate up to 10% of their
compensation for the purchase of stock. During 1997, 1998, and 1999, 520,000,
562,160, and 602,000 shares of stock were issued under the plan for an aggregate
purchase price of $7,841,000, $10,873,000, and $13,632,000, respectively. The
weighted average fair value per share of purchases in 1997, 1998, and 1999 was
$5.75, $5.11, and $7.32, respectively, and were issued at a weighted-average
price of $15.08, $19.34, and $23.25, respectively. At October 31, 1999, 908,000
shares remained unissued under the plan.

     At October 31, 1999, ABM has a capital loss carryover of $1,135,516, which
can be carried forward to offset capital gains, if any, to reduce future federal
income taxes through October 31, 2001.

12. ACQUISITIONS AND DIVESTITURES

     All acquisitions have been accounted for using the purchase method of
accounting; operations of the companies and businesses acquired have been
included in the accompanying consolidated financial statements from their
respective dates of acquisition. The excess of the purchase price over fair
value of the net assets acquired is generally included in goodwill. Most
purchase agreements provide for contingent payments based on the annual pretax
income for subsequent periods ranging generally from three to five years. Any
such future payments are generally capitalized as goodwill when paid. Cash paid
for acquisitions, including any contingent amounts based on subsequent earnings,
were approximately $11 million in 1999. In addition, common shares, with a fair
market value of approximately $1.7 million at the date of issuance, were issued

     Effective July 1, 1999, the Company acquired the operations and selected
assets of Suburban Lighting Company, with customers located in Minnesota and
other parts of the upper Midwest. The terms for the purchase of this acquisition
were a cash downpayment made at closing plus annual contingent payments based on

     Effective August 1, 1999, the Company acquired the operations and selected
assets of FaciliTech, with customers located in the Minneapolis/St. Paul
metropolitan area of Minnesota. The terms for the purchase of this acquisition

     Effective August 1, 1999, the Company acquired the operations and selected
assets of Private Patrol Agency, with customers located in San Jose, California.
The terms for the purchase of this acquisition were a cash payment made at
closing.

     These seven business combinations were accounted for under the purchase
method of accounting. The aggregate consideration paid for these acquisitions
consisted of $7,199,000. The aggregate purchase price does not include payments
of contingent consideration based upon the results of operations of the
businesses acquired.

     Effective November 1, 1999, the Company acquired the operations and
selected assets of NPS Corporation, with customers located in Anchorage, Alaska.
The terms for the purchase of this acquisition were a cash downpayment made at

selected assets of Centre City Parking, with customers located in Miami,
Florida. The terms for the purchase of this acquisition were a cash downpayment

made over five years.

13. DISCLOSURES ABOUT FAIR VALUE OF
    FINANCIAL INSTRUMENTS

     The carrying amounts reported in the balance sheet for cash and cash
equivalents approximate fair value due to the short-maturity of these
instruments.

     Financial instruments included in investments and long-term receivables
have no quoted market prices and, accordingly, a reasonable estimate of fair
market value could not be made without incurring excessive costs. However, the
Company believes by reference to stated interest rates and security held, the
fair value of the assets would not differ significantly from the carrying value.

     The fair value of the Company's long-term debt approximates carrying value
based on the quoted market prices for the same or similar issues or on the
current rates offered to the Company for debt of the same remaining maturities.

     The Company believes that it is not practical to estimate a fair market
value different from the redeemable cumulative preferred stock's carrying value
of $6.4 million, as this security was issued in conjunction with an acquisition
and has numerous features unique to this security as described in Note 9.
However, the Company believes the carrying value would not differ significantly
from the fair value.

14. SEGMENT INFORMATION

     In fiscal 1999, the Company adopted Statements of Financial Accounting
Standards (SFAS) No. 131, "Disclosures about Segments of an Enterprise and
Related Information". SFAS 131 supersedes SFAS 14, "Financial Reporting for
Segments of a Business Enterprise", replacing the industry segment approach with
the management approach. The management approach designates the internal
organization that is used by management for making operating decisions and
assessing performance as the source of the Company's reportable segments. SFAS
131 also requires disclosures about products and services, geographic areas and
major customers. The Company is organized into nine separate operating segments
as defined under SFAS 131. However the ABM Janitorial, Amtech Elevator, ABM
Engineering, Amtech Lighting and Ampco System Parking operating segments are
reportable using the quantitative threshold criteria under SFAS 131. Included in
all other segments are the ABM Facility Services, American Commercial Security,
CommAir Mechanical Services and Easterday Janitorial Supply Company segments. In
addition, the corporate expenses are not allocated, and, therefore, have been
included, as

                                       25
<PAGE>   26

in the past, to provide more meaningful information. All of these segments are
distinct business units. They are managed separately because of their unique
services, technology and marketing requirements. Nearly 100% of the operations
and related revenues are within the United States and no single customer
accounts for more than 10% of sales. The adoption of SFAS 131 had no impact on
the results of operations or financial position.

         Notwithstanding anything in these Bylaws to the contrary, no business

set forth in this Bylaw. The chairman of the meeting may, if the facts warrant,
determine that the business was not properly brought before the meeting in
accordance with the provisions of this Bylaw; and if the chairman should so
determine, the chairman shall so declare to the meeting, and any such business
not properly brought before the meeting shall not be transacted. Notwithstanding
the foregoing provisions of this Bylaw, a stockholder shall also comply with all
applicable requirements of the Exchange Act and the rules and regulations
thereunder with respect to the matters set forth in this Bylaw. Nothing in this
Bylaw shall be deemed to affect any rights of stockholders to request inclusion
of proposals in the Corporation's proxy statement pursuant to Rule 14a-8 under
the Exchange Act.

         Section 2.5. List of Stockholders. The officer who has charge of the
stock ledger of the Corporation shall prepare and make, at least ten days before
every meeting of stockholders, a complete list of stockholders entitled to vote
at the meeting, arranged in alphabetical order, and showing the address of the

Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten days prior to the meeting, either at a place within the city where the
meeting is to be held, or, if not so specified, at the place where the meeting
is to be held. The list shall also be produced and kept at the time and place of
the meeting during the whole time thereof, and may be inspected by any
stockholder who is present.

         Section 2.6. Special Meetings. Special meetings of the stockholders,
for any purpose or purposes, may be called at any time by the Board of
Directors, or by a committee of the Board of Directors which has been duly

persons.

special meeting of stockholders stating the place, date and hour of the meeting

         Section 2.9. Adjourned Meetings and Notice Thereof. Any stockholders'
meeting, annual or special, whether or not a quorum is present, may be adjourned
from time to time by the vote of a majority of the shares represented either in
person or by proxy, but in the absence of a quorum, no other business may be
transacted at such meeting, except as provided in Section 2.10 of these by-laws.

         When a stockholders' meeting is adjourned to another time or place,
notice of the adjourned meeting need not be given if the time and place thereof
are announced at the meeting at which the adjournment is taken; except that if
the adjournment is for more than thirty days or if after the adjournment a new
record date is fixed for the adjourned meeting, notice of the adjourned meeting
shall be given to each stockholder of record entitled to vote thereat.

         At the adjourned meeting, the Corporation may transact any business
which might have been transacted at the original meeting.

         Section 2.10. Quorum. The holders of a majority of the shares issued
and outstanding and entitled to vote thereat, present in person or represented
by proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise provided by statute or by the
certificate of incorporation.

         Section 2.11. Majority Vote. If a quorum is present at any meeting, the
vote of the holders of a majority of the shares having voting power, present in
person or represented by proxy, shall decide any question brought before such
meeting, unless a different vote is required on that question by express
provision of statute or of the certificate of incorporation, in which case such
express provision shall govern and control.

         The stockholders present at a duly called or held meeting at which a
quorum is present may continue to do business until adjournment, notwithstanding
the withdrawal of enough stockholders to leave less than a quorum, in any action
taken (other than adjournment) is approved by at least a majority of the shares
required to constitute a quorum, unless a different vote is required as set
forth above.

         Section 2.12. Voting. Except as otherwise provided in the certificate
of incorporation and subject to Section 8.4 of these by-laws, each stockholder
shall be entitled to one vote, in person or by proxy, for each share of capital
stock having voting power held by such stockholder, but no proxy shall be voted
or acted upon after three years from its date, unless the proxy provides for a
longer period. Vote may be viva voce or by ballot; provided, however, that
elections for directors must be by ballot.

         Any holder of shares entitled to vote on any matter may vote part of
the shares in favor of the proposal and refrain from voting the remaining shares
or vote them against the proposal, other than elections to office but, if the
stockholder fails to specify the number of shares such stockholder is voting
affirmatively, it shall be conclusively presumed that the stockholder's
approving vote is with respect to all shares said stockholder is entitled to
vote.

         Section 2.13. Stockholder Action. Any action required or permitted to
be taken by the stockholders must be effected at a duly called annual or special
meeting of such holders and may not be effected by any consent in writing by
such holders.

         Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when a person objects, at the beginning of the meeting,
to the transaction of any business because the meeting is not lawfully called or
convened; provided, that attendance at a meeting is not a waiver of any right to
object to the consideration of matters required by law or these by-laws to be
included in the notice but not so included if such objection is expressly made
at the meeting.

         Section 2.14.  Presiding  Officer.  The chairman of the Board of
Directors, if there be such officer, shall, if present, call the meetings of the
stockholders to order and shall act as the presiding officer thereof.

         Section 2.15. Secretary. The secretary of the Corporation, if present,
shall act as secretary of all meetings of the stockholders. In the absence of
the secretary, an assistant secretary if present shall act as secretary of the

such meeting.

                                    DIRECTORS

         Section 3.1. Number of Directors, Election and Term of Office. The
number of directors which shall constitute the whole board shall be nine. The
Board of Directors shall be classified, with respect to the time for which they
severally hold office, into three classes, as nearly equal in number as
possible, as determined by the Board of Directors, one class to hold office
initially for a term expiring at the annual meeting of stockholders to be held
in 1986, another class to hold office initially for a term expiring at the
annual meeting of stockholders to be held in 1987, and another class to hold
office initially for a term expiring at the annual meeting of stockholders

                                       5
<PAGE>   6

to be held in 1988, with the members of each class to hold office until their
successors are elected and qualified. At each annual meeting of stockholders,
the successors of the class of directors whose term expires at that meeting
shall be elected to hold office for a term expiring at the annual meeting of
stockholders held in the third year following the year of their election.

                  The term "entire board" as used in these by-laws means the
total number of directors which the Corporation would have if there were no
vacancies.

         Section 3.2. Vacancies. A vacancy in the Board of Directors shall be
deemed to exist in case of the death, resignation, or removal of any director,
or if the authorized number of directors be increased, or if the stockholders
fail at any annual or special meeting of stockholders to elect the full
authorized number of directors to be voted for at that meeting.

         Unless otherwise provided in the certificate of incorporation,
vacancies and newly created directorships resulting from any increase in the
authorized number of directors may be filled by a majority of the directors then
in office, although less than a quorum, or by a sole remaining director, and any
director so chosen shall hold office until the next election of the class for
which he was chosen and until his successor is fully elected and qualified,
unless sooner displaced. If at any time the Corporation should have no directors
in office, then an election of directors may be held in the manner provided by
statute. If, at the time of filling any vacancy or any newly created
directorship, the directors then in office constitute less than a majority of
the entire board (as constituted immediately prior to any such increase), the
Court of the Chancery may upon application of any stockholder or stockholders
holding at least ten percent (10%) of the total number of the shares at the time
outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships or
to replace the directors chosen by the directors then in office.

                  Section  3.3.  Powers.  The business and affairs of the
Corporation shall be managed by its Board of Directors which may exercise all
such powers of the Corporation and do all such lawful acts and things as are not
by statute or by the certificate of incorporation or by these by-laws directed
or required to be exercised or done by the stockholders.

                  Section 3.4. Compensation of Directors. The Board of Directors
shall have the authority to fix the compensation of directors. No such
compensation shall preclude any director from serving the Corporation in any
other capacity and receiving compensation therefor.

                                       6
<PAGE>   7

                  Section 3.5. Resignation. Any director may resign effective
upon giving written notice to the chief executive officer, the secretary, or the
Board of Directors of the Corporation, unless the notice specifies a later time
for the effectiveness of such resignation. If the resignation is effective at a
future time, a successor may be elected to take office when the resignation
becomes effective.

                  Section 3.6. Nominations of Directors. Only persons who are
nominated in accordance with the procedures set forth in these Bylaws shall be
eligible for election as directors. Nominations of persons for election to the
Board of Directors may be made at a meeting of stockholders (i) by the Board of
Directors or a committee appointed by the Board of Directors authorized to make
such nominations or (ii) by any stockholder of the Corporation who is a
stockholder of record at the time of giving of the notice provided for in this
Bylaw, who shall be entitled to vote for the election of directors at the
meeting and who complies with the notice procedures set forth in this Bylaw.
Nominations by stockholders shall be made pursuant to notice in writing,
delivered or mailed, postage prepaid, to the Secretary of the Corporation and
received at the principal executive offices of the Corporation (i) in the case
of an annual meeting, not less than 60 days prior to the first anniversary of
the date on which the Corporation first mailed its proxy materials for the
preceding year's annual meeting of stockholders, provided, however, that in the
event that the date of the meeting is advanced by more than 30 days or delayed
by more than 60 days from such anniversary date, notice by the stockholder must
be received not later than the close of business on the later of the 60th day
prior to such date of mailing of proxy materials or the 10th day following the
day on which public announcement of the date of the meeting is first made; or
(ii) in the case of a special meeting at which directors are to be elected, not
later than the close of business on the later of the 60th day prior to such
special meeting or the 10th day following the day on which public announcement
of the date of the meeting and of the nominees proposed by the Board of
Directors to be elected at such meeting is first made. Such stockholder's notice
shall set forth (i) the name and address of the stockholder who intends to make
the nomination and of the person or persons to be nominated; (ii) a
representation that the stockholder is a holder of record of stock of the
Corporation entitled to vote at such meeting and intends to appear in person or
by proxy at the meeting to nominate the person or persons specified in the
notice; (iii) a description of all arrangements or understandings between the
stockholder and each nominee and

                                       7
<PAGE>   8

any other person or persons (naming such person or persons) pursuant to which
the nomination or nominations are to be made by the stockholder; (iv) such other
information regarding each nominee proposed by such stockholder as would be
required to be included in a proxy statement filed pursuant to the proxy rules
of the Securities and Exchange Commission, had the nominee been nominated, or
intended to be nominated by the Board of Directors; and (v) the written consent
of such nominee to serve as a director of the Corporation if elected. At the
request of the Board of Directors, or any committee appointed by the Board of
Directors authorized to make such nominations, any person nominated by the Board
of Directors, or such committee, for election as a director shall furnish to the
Secretary of the Corporation that information required to be set forth in a
stockholder's notice of nomination that pertains to the nominee. Notwithstanding
anything in this Bylaw to the contrary, in the event that the number of
directors to be elected to the Board of Directors of the Corporation is
increased and there is no public statement naming all the nominees for Director
or specifying the size of the increased Board of Directors made by the
Corporation at least 70 days prior to the first anniversary of the preceding
year's annual meeting, a stockholder's notice required by this Bylaw shall also
be considered timely, but only with respect to nominees for any new positions
created by such increase, if it shall be delivered to the Secretary at the
principal executive offices of the Corporation not later than the close of
business on the 10th day following the day on which such public announcement is
first made by the Corporation.

         No person shall be eligible for election as a director of the
Corporation unless nominated in accordance with the procedures set forth in
these Bylaws. The chairman of the meeting may, if the facts warrant, determine
that a nomination was not made in accordance with the procedures prescribed in
this Bylaw; and if the chairman should so determine, the chairman shall so
declare to the meeting, and the defective nomination shall be disregarded.
Notwithstanding the foregoing provisions of this Bylaw, a stockholder shall also
comply with all applicable requirements of the Exchange Act, and the rules and
regulations thereunder with respect to the matters set forth in this Bylaw.

                       MEETINGS OF THE BOARD OF DIRECTORS

                  Section 4.1.  Place of Meeting.  The Board of Directors of
the Corporation may hold meetings, both regular and special, either within or
without the State of Delaware.

                  Section 4.2. Organization Meeting. Immediately after each
annual meeting of stockholders, the Board of Directors shall hold a regular
meeting for the purpose of organization, electing officers and transacting other
business. No notice of such meeting need be given. In the event such meeting is
not so held, the meeting may be held at such time and place as shall be
specified in a notice given as hereafter provided for special meetings of the
Board of Directors, or as shall be specified in a written waiver signed by all
of the directors.

                  Section 4.3. Regular Meetings. Regular meetings of the Board
of Directors may be held at such time and at such place as shall from time to
time be determined by the Board of Directors; provided, however, that if the
date so designated falls upon a legal holiday, then the meeting shall be held at
the same time and place on the next succeeding day which is not a legal holiday.
Such regular meetings may be held without notice.

                  Section 4.4. Special Meetings. Special meetings of the Board
of Directors may be called by the chairman of the board of directors, chairman
of the executive committee of the Board of Directors, the chief executive
officer or the president or on the written request of the directors constituting
a majority of the entire board.

                  Section 4.5. Notice of Special Meetings. Notice of the time
and place of special meetings of the Board of Director shall be delivered
personally to each director, or sent to each director by mail, telephone, or
telegraph. In case such notice is sent by mail or telegraphed it shall be
deposited in the United States mail or delivered to the telegraph company in the
place in which the principal office of the Corporation is located at least 48
hours prior to the time of the holding of the meeting. In case such notice is
delivered personally or by telephone, it shall be so delivered at least 24 hours
prior to the time of the holding of the meeting. Such notice shall not be
necessary if appropriate waivers, consents and/or approvals are filed in
accordance with Section 4.6 of these by-laws.

                  Section 4.6. Waiver of Notice. Notice of a meeting need not be
given to any director who signs a waiver of notice, whether before or after the
meeting, or who

                                       9
<PAGE>   10

attends the meeting without protesting, prior thereto or at its commencement,
the lack of notice to such director.

                  The transactions of any meeting of the Board of Directors,
however called and noticed or wherever held, shall be as valid as though had at
a meeting duly held after regular call and notice if a quorum is present and if,
either before or after the meeting, each of the directors not present signs a
written waiver of notice, a consent to holding the meeting or an approval of the
minutes thereof. All such waivers, consents and approvals shall be filed with
the corporate records or made a part of the minutes of the meeting.

                  Section 4.7. Quorum. At all meetings of the board, the
presence of one-third of the entire board shall constitute a quorum for the
transaction of business, and the act of a majority of the directors present at
any meetings at which there is a quorum shall be the act of the Board of
Directors, except as may be otherwise specifically provided by statute or by the
certificate of incorporation. If a quorum shall not be present at any meeting of
the Board of Directors, the directors present thereat may adjourn the meeting
without notice other than announcement at the meeting, until a quorum shall be
present. A meeting at which a quorum is initially present may continue to
transact business, notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for such
meeting.

                  Section 4.8. Adjournment. Any meeting of the Board of
Directors, whether or not a quorum is present, may be adjourned to another time
and place by the vote of a majority of the directors present. Notice of the time
and place of the adjourned meeting need not be given to absent directors if said
time and place are fixed at the meeting adjourned.

                  Section 4.9. Action Without Meeting. Unless otherwise
restricted by the certificate of incorporation or these by-laws, any action
required or permitted to be taken at any meeting of the Board of Directors or of
any committee thereof may be taken without a meeting, if all members of the
board or committee, as the case may be, consent thereto in writing, and the
writing or writings are filed with the minutes of proceedings of the board or
committee.

                  Section 4.10. Conference Communication. Unless otherwise
restricted by the certificate of incorporation or these by-laws, members of the
Board of Directors or any committee designated by the board may participate in a

stock. Such committee or committees shall have such name or names as may be
determined from time to time by resolution adopted by the Board of Directors.

                  Section 5.2.  Committee  Minutes.  Each committee shall keep

                          INDEMNIFICATION OF DIRECTORS,
                         OFFICERS, EMPLOYEES AND AGENTS

                  Section 7.1. Actions, Suits or Proceedings Other Than by or in
the Right of the Corporation. The Corporation shall indemnify any person who was
or is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Corporation) by
reason of the fact that he is or was or has agreed to become a director,
officer, employee or agent of the Corporation, or is or was serving or has
agreed to serve at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, or by reason of any action alleged to have been taken or
omitted in such capacity, against costs, charges, expenses (including attorneys'
fees) judgments, fines and amounts paid in settlement actually and reasonably
incurred by him or on his behalf in connection with such action, suit or
proceeding and any appeal therefrom, if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful; provided however, that the
foregoing indemnity shall not be applicable as to any person who is or was or
agreed to become an employee or agent of the Corporation (other than employees
or agents who are or were also officers or directors of the Corporation), or is
or was serving or agreed to serve at the request of the Corporation as an
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise (other than employees or agents who are or were also officers
or directors of any such other corporation, partnership, joint venture, trust or
enterprise), unless and until such indemnity is specifically approved by the
Board of Directors. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which he reasonably believed to be in or
not opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

                                       15
<PAGE>   16

                  Section 7.2. Actions or Suits by or in the Right of the
Corporation. The Corporation shall indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action
or suit by or in the right of the Corporation to procure a judgment in its favor
by reason of the fact that he is or was or has agreed to become a director,
officer, employee or agent of the Corporation, or is or was serving or has
agreed to serve at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, or by reason of any action alleged to have been taken or
omitted in such capacity, against costs, charges and expenses (including
attorneys' fees) actually and reasonably incurred by him or on his behalf in
connection with the defense or settlement of such action or suit and any appeal
therefrom, if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Corporation except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the Court of Chancery of Delaware or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of such liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnify for such costs, charges and expenses which the Court of Chancery or
such other court shall deem proper; provided, however, that the foregoing
indemnity shall not be applicable as to any person who is or was or agreed to
become an employee or agent of the Corporation (other than employees or agents
who are or were also officers or directors of the Corporation), or is or was
serving or agreed to serve at the request of the Corporation as an employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise other than employees or agents who are or were also officers or
directors of any such other corporation, partnership, joint venture, trust or
enterprise), unless and until such indemnity is specifically approved by the
Board of Directors.

                  Section 7.3. Indemnification for Costs, Charges and Expenses
of Successful Party. Notwithstanding the other provisions of this Article, to
the extent that a director, officer, employee or agent of the Corporation has
been successful on the merits or otherwise, including, without limitation, the
dismissal of an action without prejudice, in defense of any action, suit or
proceeding referred to in Sections 7.1 and 7.2 of this Article, or in defense of
any claim, issue or matter therein, he shall be indemnified against all costs,
charges and expenses (including attorneys' fees) actually and reasonably
incurred by him or on his behalf in connection therewith.

                                       16
<PAGE>   17

                  Section 7.4. Determination of Right to Indemnification. Any
indemnification under Sections 7.1 and 7.2 of this Article (unless ordered by a
court) shall be paid by the Corporation unless a determination is made (1) by
the Board of Directors by a majority vote of the quorum consisting of directors
who were not parties to such action, suit or proceeding, or (2) if such a quorum
is not obtainable, or, even if obtainable a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (3) by the
stockholders, that indemnification of the director, officer, employee or agent
is not proper in the circumstances because he has not met the applicable
standard of conduct set forth in Sections 7.1 and 7.2 of this Article.

                  Section 7.5. Advance of Costs, Charges and Expenses. Costs,
charges and expenses (including attorneys' fees incurred by a person referred to
in Sections 7.1 and 7.2 of this Article in defending a civil or criminal action,
suit or proceeding shall be paid by the Corporation in advance of the final
disposition of such action, suit or proceeding; providing, however, that the
payment of such costs, charges and expenses incurred by a director or officer in
his capacity as a director or officer (and not in any other capacity in which
service was or is rendered by such person while a director or officer) in
advance of the final disposition of such action, suit or proceeding shall be
made only upon receipt of an undertaking by or on behalf of the director or
officer to repay all amounts so advanced in the event that it shall ultimately
be determined that such director or officer is not entitled to be indemnified by
the Corporation as authorized in this Article. Such costs, charges and expenses
incurred by other employees and agents may be so paid upon such terms and
conditions, if any, as the Board of Directors deems appropriate. The Board of
Directors may, in the manner set forth above, and upon approval of such
director, officer, employee or agent of the Corporation, authorize the
Corporation's counsel to represent such person, in any action, suit or
proceeding, whether or not the Corporation is a party to such action suit or
proceeding.

                  Section 7.6. Procedure for Indemnification. Any
indemnification under Sections 7.1., 7.2 or 7.3, or advance of costs, charges
and expenses under Section 7.5 of this Article, shall be made promptly, and in
any event within 30 days, upon the written request of the director, officer,
employee or agent. The right to indemnification or advances as granted by this
Article shall be enforceable by the director, officer, employee or agent in any
court of competent jurisdiction, if the Corporation denies such request, in
whole or in part, or if no disposition thereof is made within 30 days. Such
persons; costs and expenses incurred in connection with successfully
establishing his

                                       17
<PAGE>   18

right to indemnification, in whole or in part, in any such action shall also be
indemnified by the Corporation. It shall be a defense to any such action (other
than an action brought to enforce a claim for the advance of costs, charges and
expenses under Section 7.5 of this Article where the required undertaking, if
any, has been received by the Corporation) that the claimant has not met the
standard of conduct set forth in Sections 7.1 or 7.2 of this Article, but the
burden of proving such defense shall be on the Corporation. Neither the failure
of the Corporation (including its Board of Directors, its independent legal
counsel, and its stockholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he has met the applicable standard of conduct set
forth in Sections 7.1 or 7.2 of this Article, nor the fact that there has been
an actual determination by the Corporation (including its Board of Directors,
its independent legal counsel, and its stockholders) that the claimant has not
met such applicable standard of conduct, shall be a defense to the action or
create a presumption that the claimant has not met the applicable standard of
conduct.

                  Section 7.7. Other Rights; Continuation of Right to
Indemnification. The indemnification provided by this Article shall not be
deemed exclusive of any other rights to which a person seeking indemnification
may be entitled under any law (common or statutory), agreement, vote of
stockholders or disinterested director or otherwise, both as to action in his
official capacity and as to action in another capacity while holding office or
while employed by or acting as agent for the Corporation, and shall continue as
to a person who has ceased to be a director, officer, employee or agent, and
shall inure to the benefit of the estate, heirs, executors and administrators of
such person. All rights to indemnification under this Article shall be deemed to
be a contract between the Corporation and each director, officer, employee or
agent of the Corporation who serves or served in such capacity at any time while
this Article is in effect. Any repeal or modification of this Article or any
repeal or modification of relevant provisions of the Delaware General
Corporation Law or any other applicable laws shall not in any way diminish any
rights to indemnification of such director, officer, employee or agent or the
obligations of the Corporation arising hereunder.

                  Section 7.8. Insurance. The Corporation shall purchase and
maintain insurance on behalf of any person who is or was or has agreed to become
a director, officer, employee or agent of the Corporation, or is or was serving
at the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against any liability

                                       18
<PAGE>   19

asserted against him and incurred by him or on his behalf in any such capacity,
or arising out of his status as such, whether or not the Corporation would have
the power to indemnify him against such liability under the provisions of this
Article, provided that such insurance is available on acceptable terms, which
determination shall be made by a vote of a majority of the entire Board of
Directors.

                  Section 7.9. Savings Clause. If this Article or any portion
hereof shall be invalidated on any ground by any court of competent
jurisdiction, then the Corporation shall nevertheless indemnify each director,
officer, employee and agent of the Corporation as to costs, charges and expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
with respect to any action, suit or proceeding, whether civil, criminal,
administrative or investigative, including an action by or in the right of the
Corporation, to the full extent permitted by any applicable portion of this
Article that shall not have been invalidated and to the full extent permitted by
applicable law.

                                  ARTICLE VIII
                                  STOCKHOLDERS

                  Section 8.1. Certificates of Stock. Every holder of shares in
the Corporation shall be entitled to have a certificate, signed by, or in the
name of the Corporation by, the chairman, the president or a vice president and
the secretary or an assistant secretary of the Corporation, or the treasurer or
an assistant treasurer, certifying the number of shares owned by him in the
Corporation. Any or all the signatures on the certificate may be a facsimile. In
case any officer, transfer agent, or registrar who has signed or whose facsimile
signature has been placed upon a certificate shall have ceased to be such
officer, transfer agent or registrar before such certificate is issued, it may
be issued by the Corporation with the same effect as if he were such officer,
transfer agent or registrar at the date of issue.

                  Section 8.2. Lost Certificates. The Board of Directors may
direct a new certificate or certificates of stock to be issued in place of any
certificate or certificates theretofore issued by the Corporation alleged to
have been lost, stolen or destroyed, upon the making of an affidavit of that
fact by the person claiming the certificate of stock to be lost, stolen or
destroyed. When authorizing such issue of a new certificate or certificates the
Corporation may, in its discretion, and as a condition precedent to the issuance
thereof, require the owner of such

                                       19
<PAGE>   20

lost, stolen or destroyed certificate or certificates, or his legal
representative, to advertise the same in such manner as it shall require and/or
to give the Corporation a bond (or other adequate security) in such sum as it
may direct as indemnity against any claim that may be made against the
Corporation on account of the alleged loss, theft or destruction of any such
certificate or the issuance of such new certificate.

                  Section 8.3. Transfer of Stock. Upon surrender to the
Corporation or the transfer agent of the Corporation of a certificate for shares
duly endorsed or accompanied by proper evidence of succession, assignment or
authority to transfer, it shall be the duty of the Corporation to issue a new
certificate to the person entitled thereto, cancel the old certificate and
record the transaction upon its books.

                  Section 8.4. Stockholders of Record. In order that the
Corporation may determine the stockholders entitled to notice of or to vote at
any meeting of the stockholders or any adjournment thereof, or entitled to
receive payment of any dividend or other distribution or allotment of any
rights, or entitled to exercise any rights in respect of any change, conversion,
or exchange of stock or for the purpose of any other lawful action, the Board of
Directors may fix, in advance, a record date, which shall not be more than sixty
nor less than ten days before the date of such meeting, nor more than sixty days
prior to any other action. A determination of stockholders of record entitled to
notice of or to vote at a meeting of stockholders shall apply to any adjournment
of the meeting, unless the Board of Directors fixes a new record date for the
adjourned meeting, but the board shall fix a new record date if the meeting is
adjourned for more than forty-five days from the date set for the original
meeting.

                  Section 8.5. No Record Date. If no record date is fixed, the
record date for determining stockholders entitled to notice of or to vote at a
meeting of stockholders shall be at the close of business at the day next
preceding the day on which notice is given, or, if notice is waived, at the end
of business of the day next preceding the day on which the meeting is held. The
record date for determining stockholders for any other purpose shall be at the
close of business on the day on which the Board of Directors adopts the
resolution relating thereto.

                  Section 8.6. Registered Stockholders. The Corporation shall be
entitled to recognize the exclusive right of a person registered on its books as
the owner of shares to receive dividends, and to vote as such owner, and to hold
liable for calls and assessments a person registered on its books as the owner
of shares, and shall not be bound to recognize any equitable or other claim to
or interest in

                                       20
<PAGE>   21

such share or shares on the part of any other person, whether or not it shall
have express or other notice thereof, except as otherwise provided by the laws
of Delaware.



                                   ARTICLE IX
                               GENERAL PROVISIONS

                  Section 10.1. Amendments. Subject to the provisions of the
Certificate of Incorporation, these by-laws may be altered, amended or repealed
at any regular meeting of the stockholders (or at any special meeting thereof
duly called for that purpose) by a vote of not less than 70% of the outstanding
stock entitled to vote at such meeting; provided that in the notice of such
special meeting notice of such purpose shall be given. Subject to the laws of
the State of Delaware, the certificate of incorporation and these by-laws, the
Board of Directors may by majority vote of those present at any meeting at which
a quorum is present amend these by-laws, or enact such other by-laws as in their
judgment may be advisable for the regulation of the conduct of the affairs of
the Corporation.

                   "TIME-VESTED" INCENTIVE STOCK OPTION PLAN
                        (December 19, 1994 Restatement)


     ABM INDUSTRIES INCORPORATED, having established the ABM Industries
Incorporated "Time-Vested" Incentive Stock Option Plan (December 19, 1994
Restatement) (the "Plan"), hereby amends the Plan, effective as of September
22, 1999 as follows:

     1.   The second paragraph of Article III of the Plan is amended and
restated in its entirety to read as follows:

          If the Company shall be the surviving corporation in any merger or
     consolidation, each outstanding option shall pertain to and apply to the
     securities to which a holder of the same number of shares of Common Stock
     that are subject to that option would have been entitled (unless the
     Committee determines the provisions of the following sentences are
     applicable to such merger or consolidation). A Change in Control of the
     Company (as defined below) shall cause each outstanding option to
     terminate, provided that each optionee in the event of a Change in Control
     which will cause his option to terminate shall have the right immediately
     prior to such Change in Control to exercise his option in whole or in
     part, subject to every limitation on the exercisability of such option
     other than any vesting provisions. For purposes hereof, a "Change in
     Control" means:

          (1)  the acquisition (other than by ABM or by an employee benefit plan
     or related trust sponsored or maintained by ABM), directly or indirectly,
     in one or more transactions, by any person or by any group of persons,
     within the meaning of Section 13(d) or 14(d) of the Securities Exchange Act
     of 1934 or any comparable successor provisions (the "Exchange Act"), of
     beneficial ownership (within the meaning of Rule 13d-3 of the Exchange Act)
     of twenty-five percent or more of either the outstanding shares of common
     stock or the combined voting power of ABM's outstanding voting securities
     entitled to vote generally, if the acquisition was not previously approved
     by the existing directors;

          (2)  the acquisition (other than by ABM or by an employee benefit plan
     or related trust sponsored or maintained by ABM), directly or indirectly,
     in one or more transactions, by any such person or by any group of persons
     of beneficial ownership (within the meaning of Rule 13d-3 of the Exchange
     Act) of fifty percent or more of either the outstanding shares of common
     stock or the combined voting power of ABM's outstanding voting securities
     entitled to vote generally, whether or not the acquisition was approved by
     the existing directors, other than an acquisition that complies with clause
     (i) and (ii) of paragraph (3);
<PAGE>   2
          (3)  consummation of a reorganization, merger or consolidation of ABM
     or the sale or other disposition of all or substantially all of ABM's
     assets unless, immediately following such event, (i) all or substantially
     all of the stockholders of ABM immediately prior to such event own,
     directly or indirectly, seventy-five percent or more of the then
     outstanding voting securities entitled to vote generally of the resulting
     corporation (including without limitation, a corporation which as a result
     of such event owns ABM or all or substantially all of ABM's assets either
     directly or through one or more subsidiaries) in substantially the same
     proportions as their ownership of ABM's outstanding voting securities
     entitled to vote generally immediately prior to such event and (ii) the
     securities of the surviving or resulting corporation received or retained
     by the stockholders of ABM is publicly traded;


          (4)  approval by the stockholders of the complete liquidation or
     dissolution of ABM; or

          (5)  a greater than one-third change in the composition of the Board
     of Directors within 24 months if not approved by a majority of the
     pre-existing directors.

     provided that, with respect of options that are outstanding as of September
     22, 1999 the following shall also apply;

     A dissolution or liquidation of the Company, a merger or consolidation in
     which the Company is not the surviving corporation or a "change in
     control" of the Company (as defined below) (each a "Terminating
     Transaction"), shall cause each outstanding option to terminate, unless
     the agreement of merger or consolidation or any agreement relating to a
     dissolution, liquidation or change in control shall otherwise provide,
     provided that each optionee in the event of a Terminating Transaction
     which will cause his option to terminate shall have the right immediately
     prior to such Terminating Transaction to exercise his option in whole or in
     part, subject to every limitation on the exercisability of such option
     other than any vesting provisions. For purposes of this proviso only,
     a"change of control" shall be deemed to have occurred when (i) a person or
     group or persons acquires fifty percent (50%) or more of the Company's
     voting securities, and (ii) the Board of Directors of the company or the
     Committee shall have determined that such a "change of control," as
     established by the Board or Committee, has been satisfied.

     IN WITNESS WHEREOF, ABM INDUSTRIES INCORPORATED, by its duly authorized
officer, has executed this Amendment No. 2 on the date indicated below.
