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, 1998 and
1997, and the related consolidated statements of income, shareholders' equity
and cash flows for each of the three years in the period ended December 31,
1998. 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, 1998 and 1997, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1998, in conformity
with generally accepted accounting principles.

                   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 electronic test and measurement
instruments with related accessories primarily in California and Texas. The
Company's corporate offices are located in Livermore, California. In addition to
the corporate offices, both modular and electronics operations 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 conducts electronics
operations 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.

     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
directly 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 45%, 52% and 37% of
the Company's consolidated rental and sales revenues for 1998, 1997 and 1996,
respectively. The increase in the Company's sales revenues in 1997 was
attributed to the Class Size Reduction Program implemented by the state of
California in 1996.

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. Rental billings for more than one month are recorded as
deferred income and recognized as rental revenue when earned.

     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.

     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 leases 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).

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

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.

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

                                        9

                                MCGRATH RENTCORP
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

the average share price for the reported period. The weighted average number of
options outstanding at December 31, 1998, 1997 and 1996 were 186,624, 199,215
and 203,414, respectively.

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 the
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
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 7. COMMON STOCK AND STOCK OPTIONS

     The Company adopted a 1998 Stock Option Plan (the "1998 Plan"), effective

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, 242,000
options have been granted with exercise prices ranging from $20.25 to $20.81.
The options vest over 5 years and expire 10 years after grant.

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

     The weighted average remaining life of the 541,122 options outstanding at
December 31, 1998, is 6.8 years. As of December 31, 1998, 1,758,000 options can
be issued under the 1998 plan.

     Statement of Financial Standards No. 123 "Accounting for Stock-Based
Compensation" ("SFAS 123") became effective for the Company in 1996. As allowed
by SFAS 123, the Company has elected to continue to follow Accounting Principles
Board Opinion No. 25 "Accounting for Stock Issued to Employees" ("APB 25") 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.

     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 contribution of $750,000 was approved for 1998 and 1997
and $650,000 for 1996.

     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, 1998, 172,408 shares
of common stock have been granted, of which 107,951 shares of common stock are
vested. Future grants of 41,109 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. Compensation expense for 1998, 1997
and 1996 under these plans was $485,000, $497,000 and $198,000 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.

     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
1996, the Company repurchased 841,100 shares of common stock for an aggregate
repurchase price of $8,779,000 or an average price of $10.44 per share. 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. As of
December 31, 1998, 819,900 shares remain authorized for repurchase (see Note 10
below).

NOTE 8. BUSINESS SEGMENTS

     As of January 1, 1998, the Company adopted Statement of Financial
Accounting Standard No. 131, "Disclosures about Segments of an Enterprise and
Related Information" (SFAS 131). The Company defined its business segments based
on the nature of operations for the purpose of reporting under SFAS 131. The
Company's three reportable segments are Mobile Modular Management 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, 1998, 1997, and 1996 for the Company's
reportable segments is shown in the following table:
