                                     PART I


ITEM 1.  BUSINESS.

GENERAL


        McGrath RentCorp ("MGRC") is a California corporation organized in 1979.
McGrath RentCorp and its majority owned subsidiary, Enviroplex, Inc.
("Enviroplex"), collectively referred to herein as the "Company", manufactures,
rents, and sells relocatable modular offices and rents and sells communications,
fiber optic and electronic test equipment with related accessories primarily in
California and Texas. The Company's corporate offices are located in Livermore,
California. In addition to the corporate offices, certain branch functions are
conducted from this facility.


        Under the trade name "Mobile Modular Management Corporation" ("MMMC"),
the Company rents and sells modular equipment and related accessories to fulfill
customers' temporary space needs. These units are used as temporary offices
adjacent to existing facilities, and are used as sales offices, construction
field offices, classrooms and for a variety of other purposes. MMMC purchases
the modulars from various manufacturers who build them to MMMC's design
specifications. MMMC operates from two branch offices in California and one in
Texas. Although MMMC's primary emphasis is on rentals, sales of modulars
routinely occur and can fluctuate quarter to quarter and from year to year
depending on customer demands and requirements. Rentals and sales to school
districts by MMMC represent a significant portion of MMMC's total revenues.


        Under the trade name "McGrath-RenTelco", the Company rents and sells
electronic equipment from Livermore, California and Richardson, Texas.
Engineers, scientists and technicians use these instruments in evaluating the
performance of their own electrical and electronic equipment, developing
products, controlling manufacturing processes and in field service applications.
These instruments are rented primarily to electronics, communications, network
systems, industrial, research and aerospace companies. The majority of
McGrath-RenTelco's rental inventory consists of instruments manufactured by
Hewlett-Packard and Tektronix.


        MGRC owns 73.2% of Enviroplex, a California corporation organized in
1991. Enviroplex manufactures portable classrooms built to the requirements of
the California Division of the State Architect ("DSA") and sells directly to
school districts. Enviroplex conducts its sales and manufacturing operations
from its facility located in Stockton, California. Since inception, MGRC has
assisted Enviroplex in a variety of corporate functions such as accounting,
human resources, facility improvements, and insurance. MGRC has not purchased
significant quantities of manufactured product from Enviroplex. Enviroplex sales
revenues were $11,150,000, $20,672,000, and $21,287,000 for 1999, 1998, and
1997, respectively.


        The rental and sale of modulars to school districts for use as portable
classrooms, restroom buildings and administrative offices for kindergarten
through grade twelve (K-12) are a significant portion of the Company's revenues.
School business comprised approximately 34%, 45%, and 52% of the Company's
consolidated rental and sales revenues for 1999, 1998, and 1997 respectively.


        Please see Note 8 to the Consolidated Financial Statements on page 29
for more information on the Company's business segments.


        The Company has 364 employees, of whom 41 are primarily administrative
and executive personnel, and the remaining 323 are engaged in manufacturing or
rental operations. None of the employees are represented by unions. The
operations of the Company share common facilities, financing, senior management,
and operating and accounting systems which results in the efficient use of
overhead. Each product line has its own sales and technical personnel.


        No single customer has accounted for more than 10% of the Company's
total revenues generated in any given year. The Company's business is not
seasonal, except for the rental and sale of classrooms, which is heaviest in the
several months prior to the opening of school each fall.



                                       1
<PAGE>   3

        The Company operates with a marketing sense throughout. The Company is
constantly searching for ways to streamline its service and to raise the quality
of each relocatable office, classroom or instrument it rents, sells or
manufactures. The Company not only rents, sells and manufactures products, it
sells an old-fashioned idea: Paying attention to our customers pays off.


        The Company's common stock is traded on the NASDAQ National Market
System under the symbol "MGRC".


        This Annual Report on Form 10-K contains statements which constitute
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. These statements appear in a number of places.
Such statements can be identified by the use of forward-looking terminology such
as "believes", "expects", "may", "estimates", "will", "should", "plans" or
"anticipates" or the negative thereof or other variations thereon or comparable
terminology, or by discussions of strategy. Readers are cautioned that any such
forward-looking statements are not guarantees of future performance and involve
significant risks and uncertainties, and that actual results may vary materially
from those in the forward-looking statements as a result of various factors.
These factors include the effectiveness of management's strategies and
decisions, general economic and business conditions, new or modified statutory
or regulatory requirements and changing prices and market conditions. This
report identifies other factors that could cause such differences. No assurance
can be given that these are all of the factors that could cause actual results
to vary materially from the forward-looking statements.



                           RELOCATABLE MODULAR OFFICES


DESCRIPTION


        Modulars are designed for use as temporary office space and may be moved
from one location to another. Modulars vary from simple single-unit construction
site offices to attractive multi-modular facilities, complete with wood
exteriors and mansard roofs. The rental fleet includes a full range of styles
and sizes. The Company considers its modulars to be among the most attractive
and well designed available. The units are constructed with wood siding,
sturdily built and physically capable of a useful life often exceeding 18 years.
Units are provided with installed heat, air conditioning, lighting, electricity
and floor covering, and may have customized interiors including partitioning,
carpeting, cabinetwork and plumbing facilities.


        MMMC purchases new modulars from various manufacturers who build to
MMMC's design specifications. None of the principal suppliers are affiliated
with the Company. During 1999, the Company purchased 51% of its modular product
from one manufacturer with multiple operations in several states. The Company
believes that the loss of its primary manufacturer of modulars would not have a
material adverse effect on its operations, however the Company could experience
higher prices and longer lead times for modular product until other
manufacturers increased their capacity.


MARKETING


        The market for modulars is broad. Businesses which have a need for
additional space and have adjacent land or a parking lot are potential
customers. The Company's largest single demand is for temporary classrooms.
Management believes the demand for classrooms is caused by shifting and
fluctuating school populations, the lack of state funds for new construction,
the need for temporary classroom space during reconstruction of older schools
and, most recently, class size reduction (see "Classroom Rentals and Sales"
below). Other applications include sales offices, administrative offices for
health care facilities, universities and museums. Large multi-modular complexes
are used by manufacturing, entertainment, energy and utility companies, and
governmental agencies. The Company's branch offices, as well as the corporate
office, are housed in various sizes of modulars.


        Since most of MMMC's customer requirements are to fill temporary space
needs, the Company's marketing emphasis is on rentals rather than sales. MMMC
solicits customers through extensive yellow-page advertising, telemarketing and
direct mail. Customers are encouraged to visit an inventory center to view
different models on display and to see a branch office, which itself is a
working example of a modular application.


        Because service is a major competitive factor in the rental of modulars,
MMMC offers quick response to requests for information, assistance in the choice
of a suitable size and floor plan, rapid delivery and timely



                                       2
<PAGE>   4

maintenance of its units, both prior to delivery of the unit and while it is on
rent. MMMC has sales and maintenance staffs trained in the Company's
understanding of excellence in service.


RENTALS


        Rental periods range from one month to ten years with a typical rental
period of one year. Most rental agreements provide no purchase options; and when
a rental agreement does provide the customer with a purchase option, it is
generally on terms attractive to MMMC.


        The customer is responsible for the costs of insuring the unit,
transporting the unit to the site, preparation of the site, installation of the
unit, dismantle and return of the unit to one of MMMC's three inventory centers
and certain costs for customization. MMMC maintains the units in good working
order while on rent. Upon return, the units are refurbished for subsequent use.
Refurbishment work can include floor tile repairs, roof maintenance, cleaning,
painting and other cosmetic repairs.


        At December 31, 1999, MMMC had 16,230 new or previously rented modulars
in its rental fleet with an aggregate original cost including accessories of
$238,449,000 or an average cost per unit of $14,700. Utilization is calculated
each month by dividing the cost of rental equipment on rent by the total cost of
rental equipment, excluding accessory equipment. At December 31, 1999, fleet
utilization was 78.1% and average fleet utilization during 1999 was 78.4%.
Excluding new equipment not previously rented, fleet utilization at December 31,
1999 was 80.2% and average fleet utilization during 1999 was 81.6%.


SALES


        In addition to operating its rental fleet, MMMC sells modulars to
customers who have a permanent use for such units. These sales arise out of its
marketing efforts for the rental fleet. Such sales can be of either new units or
used units from the rental fleet, which permits an orderly turnover of older
units. During 1999, MMMC's largest sale of modulars was for new classrooms to a
school district for approximately $1,004,000. This sale represented
approximately 6% of MMMC's sales, 3% of the Company's consolidated sales, and
less than 1% of the Company's consolidated revenues.


        MMMC provides limited 90-day warranties on used modulars and passes
through manufacturers' warranties on new units. Warranty costs have not been
significant to MMMC's operations to date, and MMMC attributes this to its
commitment to high quality standards and regular maintenance programs.


        In addition to MMMC's sales, the Company's subsidiary, Enviroplex,
manufactures and sells portable classrooms to school districts in California
(see "Classroom Sales by Enviroplex" below).


COMPETITION


        This section contains statements that constitute "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. See "General" above for cautionary information with respect to such
forward-looking statements.


        Competition in the rental and sale of relocatable modular offices is
intense. Many firms are engaged in the rental of modulars, and some have
substantially greater financial resources than MMMC. Significant competitive
factors in the rental business include availability, price, services,
reliability, appearance and functionality of the product. MMMC markets
high-quality, well constructed and attractive modulars. MMMC believes that part
of the strategy for modulars should be to create facilities and infrastructure
capabilities that its competitors cannot easily duplicate. The Company's
facilities and related infrastructure enable it to modify modulars efficiently
and cost effectively to meet its customers' needs. Management's goal is to be
more responsive at less expense. Management believes this strategy, together
with its emphasis on prompt and efficient customer service, gives MMMC a
competitive advantage. The Company is determined to offer quick response to
requests for information, experienced assistance for the first-time user, rapid
delivery and timely maintenance of its units. The efficiency and responsiveness
continues to be enhanced by the Company's computer based relational database
programs that control its internal operations. MMMC anticipates strong
competition in the future and believes the process of improvement is ongoing.

CLASSROOM SALES BY ENVIROPLEX

        This section contains statements that constitute "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. See "General" above for cautionary information with respect to such
forward-looking statements.


        Enviroplex manufactures moment-resistant, rigid steel framed portable
classrooms built to the requirements of the DSA and sells directly to school
districts. The moment-resistant, rigid steel framed classroom is engineered to
have the structural columns support the weight of the building. This offers the
customer greater design flexibility as to overall classroom size and the
placement of doors and windows. Enviroplex fabricates most of the structural
steel component parts using only mill certified sheet steel. Enviroplex's
standard designs have been engineered for strength and durability using lighter
weight steel. Customers are offered a wide variety of the DSA pre-approved
classroom sizes and features with market established pricing which could save
them valuable time on their classroom project. Additional customization features
include restrooms, computer lab setups, interior offices, cabinetwork and
kitchen facilities. During 1999, Enviroplex's largest sale was for $1,596,000 of
new classrooms to a school district. This sale represented 14% of Enviroplex's
sales, 4% of the Company's consolidated sales and 1% of the Company's
consolidated revenues.


        Competition in the manufacture of DSA classrooms is broad, intense, and
highly competitive. Several manufacturers have greater capacity for production
and have been in business longer than Enviroplex. Larger manufacturers with
greater capacity have a larger appetite for the standard classroom while
Enviroplex caters to schools' requirements for more customized classrooms. The
remaining manufacturers are of a similar size or smaller and do not have the
production capacity nor the financial resources of Enviroplex.


        Enviroplex manufactures solid, attractive classrooms. Through value
engineering, Enviroplex has simplified its manufacturing process by changing
materials, determining which components are made in-house versus purchased,
reducing the number of components and increasing the production efficiency at an
overall lower cost without sacrificing quality. Enviroplex's strategy is to
improve the quality and flexibility of its product. Enviroplex understands that
its customers want more than a quality classroom, competitively priced and
delivered on time, and believes its niche is providing customers with choices in
design flexibility and customization. Management believes this strategy gives
Enviroplex a competitive edge.


        Enviroplex provides a one-year warranty on equipment manufactured.
Warranty costs have not been significant to Enviroplex's operations to date
which can be attributed to Enviroplex's dedication to manufacturing and
delivering a quality, problem-free product.


        Enviroplex purchases raw materials from a variety of suppliers. Each
component part has multiple suppliers. Enviroplex believes the loss of any one
of these suppliers would not have a material adverse affect on its operations.


CLASSROOM RENTALS AND SALES


        The rental and sales of modulars to public school districts for use as
portable classrooms, restroom buildings and administrative offices for
kindergarten through grade twelve (K-12) are a significant portion of the
Company's revenues. The following table shows the approximate percentages
schools are of the Company's modular rental and sales revenues, and of its
consolidated rental and sales revenues for the past five years:

Consolidated Rental and Sales Revenues      34%    45%     52%    37%    27%
</TABLE>

        The increased sales shown for 1998, 1997 and 1996 can be attributed to
the Class Size Reduction Program instituted by the state of California. School
districts were given great incentive to reduce class size in the lower grades
from a typical 30 students to no greater than 20 students. This highly popular
program created a great demand for both purchasing and renting classroom
buildings.



                                       4

        In California (where most of the Company's rentals to public school
districts have occurred), school districts are permitted to purchase only
portable classrooms built to the requirements of the DSA. However, school
districts may rent classrooms that meet either the Department of Housing ("DOH")
or the DSA requirements. Prior to 1988 the majority of the classrooms in the
Company's rental fleet were built to the DOH requirements, and since 1988 almost
all new classrooms have been built to the DSA requirements. In 1988, California
adopted a law which limited the term for which school districts may rent
portable classrooms built to DOH standards to three years (under a waiver
process), and which also required the school board to indemnify the State
against any claims arising out of the use of such classrooms. In 1993, a new law
went into effect that allowed school districts which already had DOH classrooms
to continue to rent them for an additional three years (i.e. up to six years in
total). New orders for DOH classrooms placed after 1992 were restricted to the
three year limitation as before. In 1996, legislation was adopted that
eliminated the issuance of new waivers after September 30, 1997. Prior to
September 30, 1997, additional legislation was passed to extend all existing
waivers until September 30, 2000. At December 31, 1999, the net book value of
DOH classrooms represented approximately 2% of the total assets of the Company
and management believes that actions it has taken will mitigate the impact of
the expiration. Currently, regulations are in place that allow the ongoing use
of the DOH classrooms to meet the shorter term space needs of school districts
for periods up to 24 months, provided they receive a "Temporary Certification"
from the DSA. As a consequence, the tendency is for school districts to rent the
DOH classrooms for shorter periods and to rent the DSA classrooms for longer
periods.


        The Company's DOH classrooms are also suitable for rent to non-school
customers for commercial uses; however, the 24' x 40' standard classrooms are
not as popular for commercial use. The following table shows the comparison of,
and shift from, 24' x 40' standard DOH classrooms to DSA classrooms marketed to
school districts as of December 31, 1999, 1998, 1997, 1996 and 1995. Please note
how the inventory has shifted to the DSA classrooms.

                   ELECTRONIC TEST AND MEASUREMENT INSTRUMENTS


DESCRIPTION


        The Company's rental inventory includes electronic instruments such as
oscilloscopes, spectrum analyzers, logic analyzers, signal generators, frequency
counters, protocol analyzers, cable locators, fiber optic and sonet equipment.
The Company also rents electronic instruments from other rental companies and
re-rents the instruments to customers.


        At December 31, 1999, the Company had an aggregate cost of electronics
rental inventory and accessories of $72,832,000. Utilization is calculated each
month by dividing the cost of the rental equipment on rent by the total cost of
the rental equipment, excluding accessory equipment. At December 31, 1999
utilization was 54.4%, and the average utilization during 1999 was 53.8%. The
Company rents electronic equipment for a typical rental period of one to six
months at monthly rental rates ranging from approximately 3.0% to 10.0% of the
current manufacturers' list price. The Company depreciates its equipment over 5
to 8 years.


        The Company endeavors to keep its equipment fresh and attempts to sell
equipment so that the majority of the inventory is less than five years old. The
Company generally sells used equipment after approximately four years of service
to permit an orderly turnover and replenishment of the electronics inventory. In
1999, approximately 26% of the electronics revenues were derived from sales. The
largest electronics sale during 1999 represented 1% of electronics sales and
less than 1% of the Company's consolidated revenues.


MARKET


        The business of renting electronic test and measurement instruments is
an industry which today has equipment on rent or available for rent in the
United States with an aggregate original cost in excess of a half billion
dollars. While there is a broad customer base for the rental of such
instruments, most rentals are to electronics, communications, network systems,
industrial, research and aerospace companies. The Company markets its electronic
equipment throughout the United States.


        The Company believes that customers rent electronic test and measurement
instruments for many reasons. Customers frequently need equipment for short-term
projects, for backup to avoid costly downtime and to evaluate new products.
Delivery times for the purchase of such equipment can be lengthy; thus, renting
allows the customer to obtain the equipment expeditiously. The Company also
believes that a substantial portion of electronic test and measurement
instruments is used for research and development projects where the relative
certainty of rental costs can facilitate cost control and be useful in bidding
for government contracts. Finally, as is true with the rental of any equipment,
renting rather than purchasing may better satisfy the customer's budgetary
constraints.


        The industry consists of three major companies. One of these companies
is much larger than the Company, has substantially greater financial resources
and is well established in the industry with a large inventory of equipment,
several branch offices and experienced personnel.

ITEM 2.  PROPERTIES.


        The Company currently conducts its operations from five locations.
Inventory centers, at which relocatable modular offices are displayed,
refurbished and stored are located in Livermore, California (San Francisco Bay
Area), Mira Loma, California (Los Angeles Area) and Pasadena, Texas (Houston
Area). These three branches conduct rental and sales operations from
multi-modular offices, serving as working models of the Company's product.
Electronic test and measurement instrument rental and sales operations are
conducted from the Livermore facility and from a facility in Richardson, Texas
(Dallas Area). The Company's majority owned subsidiary, Enviroplex, manufactures
portable classrooms from its facility in Stockton, California (San Francisco Bay
Area).


        During 1999, the Company purchased 2.6 acres of land in Plano, Texas for
the development of a 40,000 square foot office and warehouse facility. The
primary purpose for constructing the new facility is to relocate the currently
rented Richardson, Texas electronics operation. The Company intends to rent out
approximately half the facility. Construction of the facility started in January
2000 and will be completed by July 2000 at an estimated cost of $2,000,000.


        The following table sets forth for each property the total acres, square
footage of office space, square footage of warehouse space and total square
footage at December 31, 1999. Except as noted, all properties are owned by the
Company.

expanded the rental inventory of relocatable modular offices and electronic
instruments. This expansion has been funded through internal cash flow, private
placement of long-term debt and conventional bank financing.


        The major portion of the Company's revenue is derived from rental
operations comprising approximately 71% of consolidated revenues in 1999 and 62%
of consolidated revenues for the three years ended December 31, 1999. Over the
past three years modulars comprised 71% of the cumulative rental operations, and
electronics comprised 29% of the cumulative rental operations.


        The Company sells both modular and electronic equipment that is new,
previously available for rent, or manufactured by its majority owned subsidiary,
Enviroplex. In the case of some modular equipment, the Company acts as a dealer
of relocatable modular offices and is licensed as a dealer by governmental
agencies in California and Texas. Revenues from sales of both modular and
electronic equipment have comprised approximately 28% of the Company's
consolidated revenues in 1999 and 37% of the Company's consolidated revenues
over the last three years. During these three years, modular sales represented
84% and electronic sales represented 16%.


        The rental and sale of modulars to public school districts is a
significant part of the Company's business. School business comprised 34%, 45%,
and 52% of the Company's consolidated rental and sales revenues for 1999, 1998,
1997. The increases in the Company's sales and rental revenues in 1997 can be
attributed primarily to the Class Size Reduction Program implemented by the
state of California in 1996. Sales revenues declined significantly in 1999 and
1998 as school districts' demand for classrooms declined as school districts
finished implementing the Class Size Reduction Program. (See "Business -
Relocatable Modular Offices - Classroom Rentals and Sales" above.)

FISCAL YEARS 1999 AND 1998

        This section contains statements that constitute "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. See "General" above for cautionary information with respect to such
forward-looking statements.

        As anticipated, during 1999 increased revenues from rental operations
have significantly offset the decline in sales revenues. However, net income for
1999 was reduced by the impact of both a noncash pre-tax compensation charge of
$885,000, as well as a one-time, noncash, after-tax charge of $1,367,000
reflecting the cumulative effect through December 31, 1998 of the Company's
change in accounting method for rental revenues as of January 1, 1999. After
considering the impact of these two charges, net income for 1999 was
$22,466,000, or $1.68 per diluted share compared to last year's reported net
income of $23,895,000, or $1.67 per diluted share. Excluding the impact of these
two charges, net income in 1999 would have been $24,361,000, or $1.82 per
diluted share. Assuming the newly adopted accounting method had been in effect
in 1998, net income for 1998 would have been $23,697,000, or $1.65 per diluted
share, and comparative earnings per diluted share would have increased 10% in
1999 as a result of higher earnings and fewer outstanding shares.



                                       12

        Rental revenue is recognized under the "operating method" of accounting
for the majority of leases. Effective January 1, 1999, rental revenue is
recognized ratably over the month on a daily basis. Rental billings for periods
extending beyond the month end are recorded as deferred income. In prior years,
only rental billings extending beyond a one-month period were recorded as
deferred income. The new method of recognizing revenue was adopted in response
to the Security and Exchange Commission's Staff Accounting Bulletin (SAB) No.
101, "Revenue Recognition." The effect is reported as a change in accounting
method in accordance with Accounting Principles Board Opinion ("APB") No. 20,
"Accounting Changes." The cumulative effect of changing to a new method of
accounting effective January 1, 1999 was to decrease net income by $1,367,000
(net of taxes of $883,000) or $0.10 per diluted share. The pro forma amounts
shown on the consolidated statements of income have been adjusted as if the new
method of revenue recognition had been in effect for all periods presented.

        Rental revenues increased $6,787,000 (9%) over 1998, with MMMC
contributing $3,665,000 and McGrath-RenTelco contributing $3,122,000 of the
increase. As of December 31, 1999, rental equipment on rent increased for MMMC
by $16,586,000 and for McGrath-RenTelco by $5,331,000 compared to a year
earlier. Even though average utilization for modulars increased from 77.6% in
1998 to 78.4% in 1999, the annual yield declined for modulars from 23.4% to
22.7% as a result of lower rental rates due to competition. Average utilization
for electronics declined slightly from 54.6% in 1998 to 53.8% in 1999 with
electronics annual yield declining from 42.2% in 1998 to 39.7% in 1999 resulting
primarily from competitive pricing pressures.

        Rental related services revenues in 1999 increased $1,515,000 (13%),
over 1998 as a result of a higher volume of modular equipment movements and site
requirements in 1999. Gross margins on these services increased from 43.4% in
1998 to 45.2% in 1999.

        Sales in 1999 declined $14,005,000 (27%) primarily due to a reduction in
sales of manufactured classrooms by Enviroplex to school districts from the high
levels in 1998 caused by California's Class Size Reduction Program. Further,
increased business levels for Enviroplex anticipated from the $9.2 billion
California bond measure, which passed in November 1998, did not materialize in
1999. The single largest sale in 1999 was by Enviroplex for $1,596,000 of new
classrooms to a school district. Sales continue to occur routinely as a normal
part of the Company's rental business; however, these sales can fluctuate from
quarter to quarter and year to year depending on customer demands, requirements
and funding. Consolidated gross margin on sales declined slightly from 31.1% in
1998 to 29.6% in 1999 due to the lower margin classroom projects sold during
1999.

        Enviroplex's backlog of orders as of December 31, 1999 and 1998 was
$12,626,000 and $1,468,000, respectively. (Backlog is not significant in MMMC's
modular business or in McGrath-RenTelco's electronic business.)

        Depreciation on rental equipment in 1999 increased $2,918,000 (17%) over
1998 due to additional rental equipment purchased during 1999. The average
modular rental equipment, at cost, increased $22,321,000 (11%) and average
electronics rental equipment, at cost, increased $11,561,000 (20%) over 1998.
Other direct costs of rental operations increased $894,000 (7%) over 1998
primarily due to increased maintenance and repair expenses of the modular fleet.
Additionally, during 1998 as in the prior year, a significant number of school
customers opted to include upfront charges in the rental rate resulting in
higher amortization expense of these related upfront costs over the lease term
in subsequent periods.

        Selling and administrative expenses in 1999 increased $883,000 (5%) over
1998. During 1999, the Company repurchased 80,000 shares of stock at $18.00 per
share from an employee who had acquired the stock at $6.94 per share through the
exercise of a stock option, resulting in the recognition of a noncash
compensation expense of $885,000.

        Interest expense in 1999 increased $280,000 (4%) over 1998 as a result
of higher average borrowing levels in 1999 offset by a lower weighted average
interest rate. The debt increase funded part of the significant rental equipment
purchases made during 1999.

        Income before provision for taxes in 1999 decreased $1,952,000 (5%) from
1998 while net income before effect of the accounting change only decreased
$62,000 (less than 1%) from 1998. The lower percentage decrease for net income
before effect of the accounting change is due to the decrease in the minority
interest in income of Enviroplex combined with a lower effective tax rate in
1999 of 38.1% compared to 39.1% in 1998 as more business is derived outside of
California.

FISCAL YEARS 1998 AND 1997


        California's Class Size Reduction Program (a law enacted in July 1996)
provided for facility and operational funding for the reduction of classroom
size to 20 pupils for kindergarten through third grade. Due to the anticipated
increase in demand for the DSA classrooms at the time, MMMC increased its supply
of the DSA classrooms resulting in significantly higher levels of sales and
rentals to school districts in 1997 and 1998. In late 1997 and continuing into
1998, as the industry's capacity to produce classrooms increased and the school
districts' demand for new classrooms decreased, school districts were more often
able to purchase new classrooms directly from manufacturers rather than from
MMMC. MMMC's sales of new classrooms declined from $18,795,000 in 1997 to
$10,187,000 in 1998. Included in the 1998 MMMC classroom sales is one project
that accounted for 60% of the sales volume.


        Rental revenues increased $10,279,000 (17%) over 1997, with MMMC
contributing $6,443,000 and McGrath-RenTelco contributing $3,836,000 of the
increase. The significant rental revenue increase by MMMC resulted from the
large quantities of equipment shipped to schools in the latter part of 1997. The
McGrath-RenTelco rental revenue increase resulted from additional market
penetration including telemarketing and regional sales efforts on the East
Coast. As of December 31, 1998, rental equipment on rent increased for MMMC by
$17,760,000 and for McGrath-RenTelco by $7,759,000 compared to a year earlier.


        Rental related services revenues in 1998 increased $1,250,000 (12%),
over 1997. Gross margins on these services increased from 38.8% in 1997 to 43.4%
in 1998.


        Sales in 1998 declined $10,977,000 (18%) due to fewer new classroom
sales to school districts by MMMC. Enviroplex and McGrath-RenTelco sales volumes
each declined slightly from 1997 and added to MMMC's expected decline in new
classroom sales. The single largest sale was for $6,110,000 by MMMC to a school
district during the third quarter of 1998 consisting of new classrooms of which
69% of the total contract was for demolition of existing buildings, site
improvements and installation of the new classrooms. This sale was unique as to
the volume of new classrooms sold in conjunction with the amount of site work
performed and is not likely to be repeated in the future.

        Depreciation on rental equipment in 1998 increased $2,504,000 (17%) over
1997 due to additional rental equipment purchased during 1998. Average rental
equipment, at cost, during 1998 increased 19%. Other direct costs of rental
operations increased $3,015,000 (29%) over 1997 primarily due to increased
maintenance and repair expenses of the modular fleet. Additionally, during 1997,
a significant number of school customers opted to include upfront charges in the
rental rate resulting in higher amortization expense of these related upfront
costs over the lease term in the subsequent periods.

        Selling and administrative expenses in 1998 increased $263,000 (2%) over
1997. During 1998, the primary factors contributing to increased selling and
administrative expenses were higher expenses for facility and equipment
depreciation ($585,000) and personnel and benefit costs ($539,000) offset by
fewer bad debt write-offs ($220,000), fewer legal and consulting expenses
($214,000), and eliminated facility rental, cleanup and moving expenses
($253,000).

        Interest expense in 1998 increased $2,256,000 (55%) over 1997 as a
result of higher average borrowing levels in 1998. The debt increase funded in
part the rental equipment purchases made during 1998.

        Income before provision for taxes in 1998 decreased $469,000 (1%) from
1997 while net income decreased $150,000 from 1997. Basic earnings per share
increased 6% from $1.60 in 1997 to $1.69 in 1998 due to fewer shares
outstanding.

LIQUIDITY AND CAPITAL RESOURCES


        This section contains statements that constitute "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. See "General" above for cautionary information with respect to such
forward-looking statements.


        In 1999, as in prior years, the Company's primary use of cash has been
investing in its growth by purchasing additional rental inventory of relocatable
modular offices and electronic test and measurement instruments to satisfy



                                       14
<PAGE>   16

customer requirements. During 1999, the Company purchased $47,310,000 of
equipment to add to its inventory available for rent to customers. During the
last three years, this growth in the rental inventory has been financed by cash
flow from operations, private placement of long-term debt and bank borrowings.


        The Company's operations produced a positive cash flow of $53,235,000
during 1999 as compared to $41,967,000 and $41,405,000 during 1998 and 1997
respectively.


        In July, 1998, the Company completed a private placement of $40,000,000
of 6.44% Senior Notes due in 2005. Interest on the notes is due semi-annually in
arrears and the principal is due in five equal installments commencing on July
15, 2001 (and thus, the outstanding balance at December 31, 1999, was
$40,000,000).


        Bank borrowings have long been a source of funds for the Company's
purchase of rental equipment. As the Company's assets have grown, it has been
able to negotiate increases in the borrowing limit under its general bank lines
of credit, which limit is currently $100,000,000. The Company increased its
borrowings under this line by $13,300,000 during the year, and at December 31,
1999, the outstanding borrowings under this line were $70,300,000. In addition
to the $100,000,000 line of credit, the Company has a $5,000,000 committed line
of credit facility related to its cash management services. The Company had a
total liabilities to equity ratio of 2.12 to 1 and 1.64 to 1 as of December 31,
1999 and 1998, respectively; and the debt (notes payable) to equity ratio was
1.16 to 1 and 0.92 to 1 at December 31, 1999 and 1998, respectively. Although no
assurance can be given, the Company believes it will continue to be able to
negotiate higher limits on its general bank lines of credit adequate to meet
capital requirements not otherwise met by operational cash flows and long term
debt.


        In addition to increasing its rental inventory assets, the Company also
used $2,253,000 to add to its other fixed assets, and has used significant cash
to provide returns to its shareholders, both in the form of cash dividends and
by stock repurchases. The Company has made purchases of shares of its common
stock from time to time in the over-the-counter market (NASDAQ) and/or through
privately negotiated, large block transactions under an authorization of the
Board of Directors. Shares repurchased by the Company are canceled and returned
to the status of authorized but unissued stock. As of March 17, 2000, 1,000,000
shares remain authorized for repurchase. The following table summarizes the
dividends paid and the repurchases of the Company's common stock during the past
three years.

        Please see the Company's Consolidated Statements of Cash Flows on page
21 for a more detailed presentation of the sources and uses of the Company's
cash.

        The Company does not have any material commitments or obligations
requiring the expenditure of cash in the future inconsistent with its
expenditures in the periods reported herein. The Company believes that its needs
for working capital and capital expenditures through 2000 and beyond will be
adequately met by operational cash flow, bank borrowings and long-term debt. The
Company believes that it has the ability to reduce materially the amount of cash
it uses to purchase rental equipment, pay dividends and repurchase its common
stock in the future if a need to conserve cash should arise unexpectedly.

MARKET RISK

        This section contains statements that constitute "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. See "General" above for cautionary information with respect to such
forward-looking statements.

        The Company currently has no material derivative financial instruments
which expose the Company to significant market risk. The Company is exposed to
cash flow and fair value risk due to changes in interest rates with respect to
its notes payable. The table below presents principal cash flows and related
weighted average interest rates of the Company's notes payable at December 31,
1999 by expected maturity dates. Weighted average variable rates are based on
implied forward rates in the yield curve at the reporting date.

YEAR 2000

        The Company experienced no disruption in operations due to the
transition to the Year 2000. A number of major system projects were initiated in
1997, 1998 and 1999 to upgrade core computer hardware, networking and software
systems. These projects replaced existing systems as opposed to simply fixing
Year 2000 problems; they are now complete and operational. Capitalized
expenditures for this process totaled $1,850,000 for the period January 1, 1997
to December 31, 1999 for external labor, hardware and software costs. This
amount includes the cost of new software applications installed as a result of
strategic replacement projects. Prior to December 31, 1998, the Company did not
separately track the internal costs incurred related to Year 2000 issues or the
system conversions described above. Such internal costs are principally the
related payroll costs for its information systems personnel and are not
necessarily considered incremental costs to the Company. Effective January 1,
1999, the Company began to track and capitalize these internal costs in
accordance with Statement of Position 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use." During 1999, the
Company capitalized internal personnel costs of $300,000 for software
development. There has been no material change in total cost estimates related
to Year 2000 remediation efforts. There are no known trends or deferred capital
spending related to Year 2000 issues that are likely to affect the Company's
results of operations.


IMPACT OF INFLATION


        Although the Company cannot precisely determine the effect of inflation,
from time to time it has experienced increases in costs of rental equipment,
manufacturing costs, operating expenses and interest. Because most of its
rentals are relatively short term, the Company has generally been able to pass
on such increased costs through increases in rental rates and selling prices.

Report of Independent Public Accountants
- --------------------------------------------------------------------------------



To the Shareholders and Board of Directors of McGrath RentCorp:

        We have audited the accompanying consolidated balance sheets of McGrath
RentCorp (a California corporation) and subsidiary as of December 31, 1999 and
1998, and the related consolidated statements of income, shareholders' equity
and cash flows for each of the three years in the period ended December 31,
1999. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

        We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatements. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of McGrath RentCorp as
of December 31, 1999 and 1998, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1999, in
conformity with generally accepted accounting principles.

        As explained in Note 2 to the consolidated financial statements, the
Company changed its method of accounting for rental revenue whereby all rental
revenues are recognized ratably over the month on a daily basis.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1.  ORGANIZATION AND BUSINESS

        McGrath RentCorp is a California corporation organized in 1979. McGrath
RentCorp and its majority owned subsidiary, Enviroplex, Inc. ("Enviroplex"),
collectively referred to herein as the "Company", manufactures, rents and sells
relocatable modular offices and rents and sells communications, fiber optic and
electronic test equipment with related accessories primarily in California and
Texas. The Company's corporate offices are located in Livermore, California. In
addition to the corporate offices, certain branch functions are conducted from
this facility.

        Under the trade name "Mobile Modular Management Corporation", the
Company rents and sells modular equipment and related accessories from two
branch offices located in California and one located in Texas. The Company
purchases the modulars from various manufacturers who build them to the
Company's design specifications. Although Mobile Modular Management
Corporation's primary emphasis is on rentals, sales of modulars occur routinely
and can fluctuate quarter to quarter and from year to year depending on customer
demands and requirements.

        Under the trade name "McGrath-RenTelco", the Company rents and sells
electronic instruments from Livermore, California and Richardson, Texas.
Engineers, scientists, technicians and field-service personnel use these
instruments in evaluating the performance of their own electrical and electronic
equipment, developing products, controlling manufacturing processes and in-field
service applications. These instruments are rented primarily to electronics,
communications, network systems, industrial, research and aerospace companies.
The majority of McGrath-RenTelco's rental inventory consists of instruments
manufactured by Hewlett-Packard and Tektronix.

        McGrath RentCorp owns 73.2% of Enviroplex, a California corporation
organized in 1991. Enviroplex manufactures portable classrooms built to the
requirements of the California Division of the State Architect ("DSA") and sells
primarily to school districts. Enviroplex conducts its sales and manufacturing
operations from one facility located in Stockton, California.

        The rental and sale of modulars to public school districts for use as
portable classrooms, restroom buildings and administrative offices for
kindergarten through grade twelve (K-12) are a significant portion of the
Company's revenues. School business comprised approximately 34%, 45% and 52% of
the Company's consolidated rental and sales revenues for 1999, 1998 and 1997,
respectively.


NOTE 2.  SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

        The consolidated financial statements include the accounts of McGrath
RentCorp and Enviroplex. All significant intercompany accounts and transactions
are eliminated.

REVENUES

        Rental revenue is recognized under the "operating method" of accounting
for the majority of leases. Effective January 1, 1999, rental revenue is
recognized ratably over the month on a daily basis. Rental billings for periods
extending beyond the month end are recorded as deferred income. In prior years,
only rental billings extending beyond a one-month period were recorded as
deferred income. The new method of recognizing revenue was adopted in response
to the Security and Exchange Commission's Staff Accounting Bulletin (SAB) No.
101, "Revenue Recognition." The effect is reported as a change in accounting
method in accordance with Accounting Principles Board Opinion ("APB") No. 20,
"Accounting Changes." The cumulative effect of changing to a new method of
accounting effective January 1, 1999 was to decrease net income by $1,367,000
(net of taxes of $883,000) or $0.10 per diluted share. The pro forma amounts
shown on the consolidated statements of income have been adjusted as if the new
method of revenue recognition had been in effect for all periods presented.

        Rental related services revenue is primarily associated with relocatable
modular office leases and consists of billings to customers for delivery,
installation, modifications, skirting, additional site related work, and return
delivery and dismantle. Revenue related to these services is recognized in the
period the services are performed and accepted.



                                       22
<PAGE>   24

                                MCGRATH RENTCORP
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

        Sales revenue is recognized upon delivery of the equipment to the
customer. Certain leases meeting the requirements of Statement of Financial
Accounting Standards ("SFAS") No. 13, "Accounting for Leases," are accounted for
as sales type leases. For these leases, sales revenue and the related accounts
receivable are recognized upon execution of the lease and unearned interest is
recognized over the lease term on a basis which results in a constant rate of
return on the unrecovered lease investment (see Note 4).

DEPRECIATION AND MAINTENANCE

        Rental equipment, buildings, land improvements, equipment and furniture
are depreciated on a straight-line basis for financial reporting purposes and on
an accelerated basis for income tax purposes. The costs of major refurbishment
of relocatable modular offices are capitalized to the extent the refurbishment
significantly improves the quality and adds value or life to the equipment. Land
improvements consist of development costs incurred to build storage and
maintenance facilities at each of the relocatable modular branch offices. The
following estimated useful lives and residual values are used for financial
reporting purposes:

        Rental equipment:

<TABLE>
<S>                                                              <C>
             Relocatable modular offices                         7 to 18 years, 0% to 18% residual value

             Electronic test instruments                         5 to 8 years, no residual value

        Buildings, land improvements, equipment and furniture    5 to 50 years, no residual value
</TABLE>

Maintenance and repairs are expensed as incurred.

OTHER DIRECT COSTS OF RENTAL OPERATION

        Other direct costs of rental operations primarily relate to costs
associated with relocatable modular offices and include equipment supplies and
repairs, direct labor, amortization of lease costs included in the rental rate,
property and liability insurance, property taxes, and business and license fees.

WARRANTY SERVICE COSTS


        Sales of new relocatable modular offices, electronic test equipment and
related accessories not manufactured by the Company are typically covered by
warranties provided by the manufacturer of the products sold. The Company
provides limited 90-day warranties for certain sales of used rental equipment
and a one-year warranty on equipment manufactured by Enviroplex. Although the
Company's policy is to provide reserves for warranties when required for
specific circumstances, the Company has not found it necessary to establish such
reserves to date.


INCOME TAXES


        Provision has been made for deferred income taxes based upon the amount
of taxes payable in future years, after considering changes in tax rates and
other statutory provisions that will be in effect in those years (see Note 6).


FAIR VALUE OF FINANCIAL INSTRUMENTS


        The Company believes that the carrying amounts of its financial
instruments (cash and notes payable) approximate fair value.


USE OF ESTIMATES


        The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions in determining reported amounts of assets and liabilities,
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during each period
presented. Actual results could differ from those estimates.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

EARNINGS PER SHARE


        Basic earnings per share ("EPS") is computed as net income divided by
the weighted average number of shares of common stock outstanding for the
reported period, excluding the dilutive effects of stock options and other
potentially dilutive securities. Diluted EPS is computed as net income divided
by the weighted average number of shares outstanding of common stock and common
stock equivalents for the reported period. Common stock equivalents result from
dilutive stock options computed using the treasury stock method with the average
share price for the reported period. The weighted average number of dilutive
options outstanding at December 31, 1999, 1998 and 1997 were 147,789, 186,624
and 199,215, respectively.


COMPREHENSIVE INCOME


        SFAS No. 130, "Reporting Comprehensive Income," establishes standards to
measure all changes in equity that result from transactions and other economic
events other than transactions with shareholders. Comprehensive income is the
total of net income and all other non-shareholder changes in equity. Other than
net income, the Company has no comprehensive income.


RECLASSIFICATIONS

        Certain prior period amounts have been reclassified to conform to
current year presentation.




NOTE 3.  CONCENTRATION OF CREDIT RISK


        Financial instruments that potentially subject the Company to
concentration of credit risk consist primarily of trade accounts receivable. The
Company sells primarily on 30-day terms, individually performs credit evaluation
procedures on its customers on each transaction and will require security
deposits or personal guarantees from its customers when a significant credit
risk is identified. Historically, the Company has not incurred significant
credit related losses, however, an allowance for potential credit losses is
maintained. Typically, most customers are established companies or are publicly
funded entities located in California or Texas. Although no one customer
accounts for more than 10% of the Company's consolidated revenues, credit risk
exists in trade accounts receivable primarily due to the significant amount of
business transacted with California public school districts (K-12) which
represents a significant portion of the Company's revenues (see Note 1). The
lack of fiscal funding or a significant reduction of funding from the State of
California to the public schools could have a material adverse effect on the
Company.



NOTE 4.  SALES TYPE LEASE RECEIVABLES


        The Company has entered into several sales type leases. The minimum
lease payments receivable and the net investment included in accounts receivable
for such leases are as follows:

NOTE 5.  NOTES PAYABLE

        On July 31, 1998, the Company completed a private placement of
$40,000,000 of 6.44% Senior Notes due in 2005. Interest on the notes is due
semi-annually in arrears and the principal is due in 5 equal installments
commencing on July 15, 2001. The outstanding balance at December 31, 1999 was
$40,000,000. Among other restrictions, the agreement requires (i) the Company to
maintain a minimum net worth of $80,000,000 plus 25% of all net income generated
subsequent to June 30, 1998, less an aggregate amount not to exceed $15,000,000

(restricted equity at December 31, 1999 is $73,855,000), (ii) a fixed coverage
charge of not less than 2.0 to 1.0, (iii) a rolling fixed charges coverage ratio
of not less than 1.5 to 1.0, and (iv) senior debt not to exceed 275% of

        The Company maintains an unsecured line of credit agreement, as amended,
(the "Agreement") with its banks which expires on June 30, 2001 and permits it
to borrow up to $100,000,000 of which $70,300,000 was outstanding as of December
31, 1999. The Agreement requires the Company to pay interest at prime or, at the

amend or renegotiate the present Agreement for an additional time period prior
to its expiration date, the principal amount outstanding at that time will be
converted to a two-year term loan with principal due and payable in eight (8)
consecutive quarterly installments.

        In addition to the $100,000,000 unsecured line of credit, the Company
has a $5,000,000 committed line of credit facility (at prime rate) related to
its cash management services of which none was outstanding as of December 31,
1999. This committed line related to its cash management services will expire on
June 30, 2000.

NOTE 7.  COMMON STOCK AND STOCK OPTIONS

        The Company adopted a 1998 Stock Option Plan (the "1998 Plan"),
effective March 9, 1998, under which 2,000,000 shares are reserved for the grant
of options to purchase common stock to directors, officers, key employees and
advisors of the Company. The plan provides for the award of options at a price
not less than the fair market value of the stock as determined by the Board of
Directors on the date the options are granted. Under the 1998 Plan, 345,500
options have been granted with exercise prices ranging from $18.25 to $20.81.
The options vest over 5 years and expire 10 years after grant. To date, no
options have been issued to any of the Company's advisors. As of December 31,
1999, 1,654,500 options remain available to issue under the 1998 plan.

        The Company adopted a 1987 Incentive Stock Option Plan (the "1987
Plan"), effective December 14, 1987, under which options to purchase common
stock may be granted to officers and key employees of the Company. The plan
provides for the award of options at a price not less than the fair market value
of the stock as determined by the Board of Directors on the date the options are
granted. Under the 1987 Plan, options have been granted with an exercise price
of $3.06, $6.94 and $10.75 per share. The options vest over 9.3 years and expire
10 years after grant. The 1987 Plan expired in December 1997 and no further
options can be issued under this plan.

        Option activity and options exercisable including weighted average
exercise price for the three years ended December 31, 1999 are as follows:

        SFAS 123 "Accounting for Stock-Based Compensation" became effective for
the Company in 1996. As allowed by SFAS 123, the Company has elected to continue
to follow APB 25 "Accounting for Stock Issued to Employees" in accounting for
its stock option plans. Under APB 25, the Company does not recognize
compensation expense on the issuance of stock options because the option terms
are fixed and the exercise price equals the market price of the underlying stock
on the grant date. However, APB 25 requires recognition of noncash compensation
when the Company repurchases stock acquired by an employee through the exercise
of an incentive stock option. During 1999, the Company repurchased 80,000 shares
of stock at $18.00 per share from an employee who had acquired the stock at
$6.94 per share through the exercise of a stock option, resulting in the
recognition of noncash compensation expense of $885,000. The noncash
compensation of $885,000 is included in the Company's consolidated statements of
income in selling and administrative expense.


        In accordance with SFAS 123, the fair value of each option grant is
estimated at the date of grant using the Black-Scholes option-pricing model. The
assumptions used in the 1999 and 1998 grants are as follows:

     In 1985, the Company established an Employee Stock Ownership Plan, as
amended. Under the terms of the plan, the Company makes annual contributions in
the form of cash or common stock of the Company to a trust for the benefit of
eligible employees. The amount of the contribution is determined annually by the
Board of Directors. A cash contribution of $750,000 was approved in each year
for 1999, 1998 and 1997.


     In 1991, the Board of Directors adopted a Long-Term Stock Bonus Plan (the
"LTB Plan") under which 400,000 shares of common stock are reserved for grant to
officers and key employees. The stock bonuses granted under the LTB Plan are
evidenced by written Stock Bonus Agreements covering specified performance
periods. The LTB Plan provides for the grant of stock bonuses upon achievement
of certain financial goals during a specified period. Stock bonuses earned under
the LTB Plan vest over 5 years from the grant date contingent on the employee's
continued employment with the Company. As of December 31, 1999, 198,559 shares
of common stock have been granted, of which 137,211 shares are vested. Future
grants of 35,364 shares of common stock are authorized by the Board of Directors
to be issued under the LTB Plan in the event the Company reaches the highest
level of achievement. The LTB Plan expired in December 1999 and no further
grants of common stock can occur under the LTB Plan. Compensation expense for
1999, 1998 and 1997 under these plans was $458,000, $485,000 and $497,000
respectively, and is based on a combination of the anticipated shares to be
granted, the amount of vested shares previously issued and fluctuations in
market price of the Company's common stock. As of December 31, 1999, 1998, and
1997, the unvested shares were 61,348, 64,457 and 57,709, respectively, with the
related weighted average grant-date fair value of these unvested shares of
$20.23, $20.42 and $18.10 per share, respectively.


     The Board of Directors has authorized the repurchase of shares of the
Company's outstanding common stock. These purchases are to be made in the
over-the-counter market and/or through large block transactions at such
repurchase price as the officers shall deem appropriate and desirable on behalf
of the Company. All shares repurchased by the Company are to be canceled and
returned to the status of authorized but unissued shares of common stock. In
1997, the Company repurchased 502,408 shares of common stock for an aggregate
repurchase price of $10,545,000 or an average price of $20.99 per share. In
1998, the Company repurchased 619,550 shares of common stock for an aggregate
repurchase price of $12,247,000 or an average price of $19.77 per share. In
1999, the Company repurchased 1,549,526 shares of common stock for an aggregate
repurchase price of $28,212,000 or an average price of $18.21 per share. As of
December 31, 1999, 685,940 shares remain authorized for repurchase.

Corporation (Modulars), McGrath-RenTelco (Electronics), and Enviroplex. The
operations of each of these segments is described in Note 1, Organization and
Business, and the accounting policies of the segments are described in Note 2,
Significant Accounting Policies. As a separate corporate entity, Enviroplex
revenues and expenses are separately maintained from Modulars and Electronics.
Excluding interest expense, allocations of revenues and expenses not directly
associated with Modulars or Electronics are generally allocated to these
segments based on their pro-rata share of direct revenues. Interest expense is
allocated between Modulars and Electronics based on their pro-rata share of
average rental equipment, accounts receivable and customer security deposits.
The Company does not report total assets by business segment. Summarized
financial information for the years ended December 31, 1999, 1998, and 1997 for
the Company's reportable segments is shown in the following table:

                                 AMENDMENT NO. 1
                                       TO
                      AMENDED AND RESTATED CREDIT AGREEMENT

      This Amendment No. 1 to Amended and Restated Credit Agreement (this
"Amendment") is dated as of December 15, 1999, by and among McGRATH RENTCORP, a
California corporation (the "Borrower"), the banks listed on the signature pages
hereof (individually a "Bank" and collectively "Banks"), and UNION BANK OF
CALIFORNIA, N.A., as agent (the "Agent") for Banks.

                                    Recitals

        A. Agent, Banks and Borrower are parties to an Amended and Restated Loan
Agreement dated as of June 30, 1999 (as amended, modified and supplemented from
time to time, the "Credit Agreement").

        B. Borrower wishes to increase the aggregate Commitment from the Banks
from $75 million to $100 million and to relax the minimum tangible net worth
requirements of the Credit Agreement. Banks are willing to so increase the
Commitment and to amend the Credit Agreement in other respects on and subject to
the terms and conditions set forth in this Amendment.

        C. Each capitalized term used but not otherwise defined herein shall
have the meaning ascribed thereto in the Credit Agreement.

        NOW, THEREFORE, the parties hereto hereby agree as follows:


                                    ARTICLE I
                         AMENDMENTS TO CREDIT AGREEMENT

        This Amendment shall be deemed to be an amendment to the Credit
Agreement and shall not be construed in any way as a replacement or substitution
therefor. All of the terms and conditions of, and terms defined in, this
Amendment are hereby incorporated by reference into the Credit Agreement as if
such terms and provisions were set forth in full therein.

        1.1 Borrower has requested that Banks amend the Credit Agreement in
certain respects, including the extension of additional credit in the form of a
$25 million increase in the Commitment. Banks are willing to increase the
Commitment and to amend the Credit Agreement on the terms and conditions set
forth in this Amendment .

        1.2 Article 1 of the Credit Agreement, entitled "Definitions," is hereby
amended as follows:

               (a) The definition of "Commitment" is amended by replacing the
reference to "Seventy-Five Million Dollars ($75,000,000)" therein to "One
Hundred Million Dollars ($100,000,000)."

               (b) A new defined term "Leverage Ratio" is added, as follows:

               "Leverage Ratio" means, as of any date of determination, the
               ratio of Borrower's Liabilities as of such date to Tangible Net
               Worth as of such date.

               (c) The first sentence of Section 1.2 of the Credit Agreement,
"Accounting Terms," is hereby amended and restated in its entirety, to read
follows:

               "All accounting terms not specifically defined in this Agreement
               shall be construed, and all financial data and ratios required to
               be submitted pursuant to this Agreement shall be prepared in
               conformity with GAAP and on a consolidated basis for Borrower and
               its Subsidiaries, except as otherwise specifically provided in
               this Agreement."

        1.3 Section 2.3.2 of the Credit Agreement is hereby amended and restated
in its entirety as follows:

               2.3.2 Rate Options and Applicable Margins. The Rate Options and
               Applicable Margins for Loans shall be determined based upon the
               type of Loan and the current Leverage Ratio, as set forth in the
               table below:

               The Applicable Margin shall be subject to reduction or increase,
               as applicable and as set forth in the table above, on a quarterly
               basis according to the performance of Borrower as measured by the
               Leverage Ratio for the immediately preceding fiscal quarter of
               Borrower. Any such increase or reduction in the Applicable Margin
               shall be effective on the next Business Day after receipt by
               Agent of the applicable financial statements and the
               corresponding Compliance Certificate. If the financial statements
               and the Compliance Certificate of Borrower setting forth the
               Leverage Ratio is not received by the Agent by the date required
               pursuant to this Agreement, the Applicable Margin shall be
               determined as if the Leverage Ratio exceeds 2.25 to 1.00,
               commencing on the date when Borrower's time to deliver such
               financial statements and Compliance Certificate shall have
               expired and continuing until such time as such financial
               statements and Compliance Certificate are received and any Event
               of Default resulting from a failure to timely deliver such
               financial statements or Compliance Certificate has been waived in
               writing by the Required Banks.

               Effective as of the date of this Amendment and continuing until
the next adjustment required under Section 2.3.2, the Applicable Margin on
outstanding Revolving Loans is 0.85%, based on Borrower's most recently reported
Leverage Ratio.

        1.4 The form of Compliance Certificate referenced in Section 7.3(c) of
the Credit Agreement and attached thereto as Exhibit A is hereby replaced in its
entirety with the form of Compliance Certificate attached to this Amendment as
Exhibit "A".

        1.5 Section 7.11(a) of the Credit Agreement is hereby amended and
restated in its entirety as follows:

               (a) Tangible Net Worth at all times of at least the sum of (i)
            Seventy-Five Million Dollars ($75,000,000), plus (ii) fifty percent
            (50%) of Borrower's Net Income (without reduction for any Net Loss)
            generated after September 30, 1999, plus (iii) ninety percent (90%)
            of the proceeds from the issuance of Borrower's capital stock after
            September 30, 1999, excluding the first Two Million Dollars
            ($2,000,000) of such proceeds from the exercise of stock options
            after September 30, 1999.

        1.6 A new Section 10.9 is added to Article 10 of the Credit Agreement,
as follows:

               10.9 IRS WITHHOLDING REPRESENTATION. Each Bank represents and
            warrants that it is entitled to receive any payments hereunder
            without the withholding of any tax and will furnish to Agent such
            forms, certifications, statements and other documents as Agent may
            request from time to time to evidence such Bank's exemption from the
            withholding of any tax imposed by any jurisdiction or to enable
            Agent to comply with any applicable laws or regulations relating
            thereto.

            Without limiting the effect of the foregoing, if any Bank is not
            created or organized under the laws of the United States or any
            state thereof, such Bank further represents and warrants that it is
            engaged in the conduct of a business within the United States and
            that the payments made hereunder are or are reasonably


<PAGE>   3
            expected to be effectively connected with the conduct of that trade
            or business and are or will be includible in its gross income or, if
            Bank is not engaged in a U.S. trade or business with which such
            payments are effectively connected, that such Bank is entitled to
            the benefits of a tax convention which exempts the income from U.S.
            withholding tax and that it has satisfied all requirements to
            qualify for the exemption from tax.

            Each Bank agrees that it will, immediately upon the request of
            Agent, furnish to Agent Form 4224 or Form 1001 of the Internal
            Revenue Service, or such other forms, certifications, statements or
            documents, duly executed and completed by such Bank as evidence of
            its exemption from the withholding of U.S. tax with respect thereto.
            If any Bank determines that, as a result of any change in applicable
            law, regulation, or treaty or in any official application or
            interpretation thereof, it ceases to qualify for exemption from any
            tax imposed by any jurisdiction with respect to payments made
            hereunder, such Bank shall promptly notify Agent of such fact and
            Agent may, but shall not be required to withhold the amount of any
            such applicable tax from amounts paid to such Bank hereunder. Agent
            shall not be obligated to make any payments hereunder to such Bank
            in respect of its Loans until such Bank shall have furnished to
            Agent the requested form, certification, statement or document and
            may withhold the amount of such applicable tax from amounts paid to
            Bank hereunder.

            Each Bank shall reimburse, indemnify and hold Agent harmless for any
            and all liabilities, obligations, losses, damages, penalties,
            actions, judgments, suits, costs, expenses or disbursements of any
            kind or nature whatsoever which may be imposed upon, incurred by or
            asserted against Agent due to its reliance upon the representation
            hereby made that such Bank is exempt from withholding of tax. Unless
            Agent receives written notice to the contrary, each Bank shall be
            deemed to have made the representations contained in this Section
            and in each subsequent tax year of such Bank.

        1.7 For purposes of Section 11.20 of the Credit Agreement, the addresses
of the parties set forth on the signature pages to this Amendment shall
supercede, and be used for notices and other communications after the date
hereof instead of the addresses set forth on the signature pages to the Credit
Agreement.


                                   ARTICLE II
                           CONDITIONS TO EFFECTIVENESS
                                  OF AMENDMENT

        2.1 The effectiveness of this Amendment is subject to the fulfillment to
the satisfaction of Agent, in its sole discretion, of the following conditions
precedent:

               (a) Borrower shall have executed and delivered to Banks this
Amendment, and the three (3) replacement Revolving Notes, one payable to each
Bank, in the form attached hereto as Exhibit "B";

               (b) Borrower shall have paid to Agent for ratable distribution to
Banks, a one-time facility fee in the amount of $40,000 in connection with the
increase in the Commitment and this Amendment, and shall have reimbursed Agent
its costs and expenses, including attorneys' fees and costs not to exceed
$1,500.00, incurred in connection with the negotiation, preparation and closing
of this Amendment.

               (c) Agent shall have received appropriate authorization
documents, including borrowing resolutions and certificates of incumbency,
confirming to Agent's satisfaction that all necessary corporate and
organizational actions have been taken to authorize Borrower to enter into this
Amendment ; and

               (d) Agent shall have received such other documents, instruments
or agreements as Agent may require to effectuate the intents and purposes of
this Amendment.

                                   ARTICLE III

Credit Agreement after giving effect to this Amendment.

        3.2 Borrower has full corporate power and authority to execute and
deliver this Amendment, to make and deliver the replacement Revolving Notes, and
to perform the obligations of its part to be performed thereunder and under the
Credit Agreement as amended hereby. Borrower has taken all necessary action,
corporate or otherwise, to authorize the execution and delivery of this
Amendment and each of the documents described herein. No consent or approval of
any person, no consent or approval of any landlord or mortgagee, no waiver of

any governmental authority or agency is or will be required in connection with
the execution or delivery by Borrower of this Amendment or the performance by
Borrower of the Credit Agreement as amended hereby.

        3.3 This Amendment, the replacement Revolving Notes and the Credit
Agreement as amended hereby are, or upon delivery thereof to Banks will be, the
legal, valid and binding obligations of Borrower, enforceable against Borrower
in accordance with their respective terms, except as such enforceability may be
limited by bankruptcy, insolvency, reorganization or similar laws affecting
creditors' rights generally.


                                   ARTICLE IV
                                  MISCELLANEOUS
