                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1998

NOTE 1.   CONSOLIDATED FINANCIAL INFORMATION

        The consolidated financial information for the nine months ended
September 30, 1998 has not been audited, but in the opinion of management, all
adjustments (consisting of only normal recurring accruals, consolidation and
eliminating entries) necessary for the fair presentation of the consolidated
results of operations, financial position, and cash flows of McGrath RentCorp
(the "Company") have been made. The consolidated results of the nine months
ended September 30, 1998 should not be considered as necessarily indicative of
the consolidated results for the entire year. It is suggested that these
consolidated financial statements be read in conjunction with the financial
statements and notes thereto included in the Company's latest Form 10-K.

NOTE 2.  NOTES PAYABLE

        On July 31, 1998, the Company restructured a portion of its debt to a
fixed rate by completing a private placement of $40,000,000 of 6.44% senior
notes due in 2005 through BancAmerica Robertson Stephens. Interest on the notes
is due semi-annually in arrears and the principal is due in 5 equal installments
commencing on July 31, 2001. Upon completion of the private placement, the
Company repaid a $15,000,000 interim loan with one of its banks. The remainder
of the proceeds was applied to reduce the existing revolver.

        In August 1998, the Company reduced its capacity to borrow under its
unsecured line of credit with its banks from $90,000,000 to $75,000,000. All
other terms and conditions under this facility remained the same. In addition,
the Company extended the expiration date of its $3,000,000 committed line of
credit facility related to its cash management services to June 30, 1999 and
allowed the $10,000,000 of uncommitted optional facilities to expire.

NOTE 3.  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, 242,000
options have been granted with exercise prices ranging from $20.25 to $20.81. Of
the 242,000 options granted, key employees received 192,000. The options become
exercisable during term of the related option agreement and expire ten years
after grant.

ITEM 2. MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

THREE AND NINE MONTHS ENDED SEPTEMBER 30, 1998 AND 1997

         Rental revenues for the three and nine months ended September 30, 1998
increased $2,317,285 (14%) and $7,567,342 (17%), respectively, over the
comparative periods in 1997. Of the nine-month increase, Mobile Modular
Management Corporation ("MMMC") contributed $5,046,487 (67%) increasing from
$30,311,031 to $35,357,518 and ELECTRONICS contributed $2,520,855 (33%)
increasing from $14,827,521 to $17,348,376. The significant rental revenue
increase by MMMC resulted from the large quantities of equipment shipped to
schools in the latter part of 1997 and the ELECTRONICS rental revenue increase
resulted in part from market penetration by telemarketing and regional sales
efforts on the East Coast. As of September 30, 1998, rental equipment on rent
increased for MMMC by $19,224,379 and for ELECTRONICS increased by $4,961,500
compared to a year earlier. Average utilization for ELECTRONICS during the first
nine months increased from 54.7% in 1997 to 55.0% in 1998 and increased for
modulars from 81.0% in 1997 to 82.7% in 1998, exclusive of new equipment not
previously rented.

         Rental related services revenues for the three and nine months ended
September 30, 1998 increased $704,102 (21%) and $880,015 (11%), respectively, as
compared to the same periods in 1997. Gross margins increased from 40% to 43% in
1998 for the comparative nine-month period.

         Sales for the three and nine months ended September 30, 1998 declined
$3,888,162 (15%) and $8,648,798 (17%), respectively, as compared to the same
periods in 1997 due to fewer new classroom sales to school districts by MMMC.
Enviroplex and ELECTRONICS sales volumes increased 9% and 6%, respectively, over
the 1997 comparative nine-month period which partially offset MMMC's expected
decline in new classroom sales. (See 1997 Form 10-K Management Discussion and
Analysis for Fiscal Years 1997 and 1996.) Consolidated gross margin on sales
remained constant at 31% for 1997 and 1998. The single largest sale was for
$6,109,692 by MMMC to a school district during the third quarter of 1998
consisting of new classrooms of which 69% of the total contract was the
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. 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 and requirements.

         Depreciation on rental equipment for the three and nine months ended
September 30, 1998 increased $968,103 (27%) and $1,737,253 (16%) over the
comparative periods in 1997 as a result of additions to the rental equipment of
both modulars and electronics. Rental equipment, at cost, increased 18% between
September 30, 1997 and September 30, 1998. Other direct costs of rental
operations for the three and nine months ended September 30, 1998 increased
$1,006,185 (38%) and $2,721,118 (36%) over the comparative periods in 1997
primarily due to increased maintenance and repair expenses of the modular fleet.
Additionally, during 1997, a significant number of 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 for the three and nine months ended
September 30, 1998 decreased $401,835 (8%) and increased $95,343 (1%),
respectively, compared to the same periods in 1997. Even though selling and
administrative expenses for the nine month comparative period were approximately
the same, the three-month comparative period declined by 8% primarily due to
higher expenses for facility and equipment depreciation ($174,819) and personnel
and benefit costs ($176,883) offset by reduced performance and incentive bonuses
($528,384), fewer bad debt writeoffs ($114,023), and eliminated facility rental,
cleanup and moving expenses ($114,215).

         Interest expense for the three and nine months ended September 30, 1998
increased $643,189 (62%) and $1,814,588 (62%) over the comparative periods in
1997 as a result of higher average borrowing 



                                       6

levels in 1998. The debt increase was primarily due to rental equipment
purchases made during 1997 and 1998.

         Net income for the three and nine months ended September 30, 1998
decreased slightly as compared to the comparative periods in 1997. Earnings per
share decreased slightly for the three-month and increased for the nine-month
periods in 1998 to $0.50 per share and $1.27 per share, respectively, due to
fewer shares outstanding.


LIQUIDITY AND CAPITAL RESOURCES

        The Company had total liabilities to equity ratio of 1.72 to 1 and 1.56
to 1 as of September 30, 1998 and December 31, 1997, respectively. The debt
(notes payable) to equity ratio was 0.99 to 1 and 0.83 to 1 as of September 30,
1998 and December 31, 1997, respectively.

        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 cancelled and returned to the
status of authorized but unissued stock. As of November 5, 1998, the Company has
repurchased 587,050 shares of its outstanding common stock during the year for
an aggregate purchase price of $11,617,155 (or an average price of $19.79 per
share). As of November 5, 1998, 852,400 shares remain authorized for repurchase.

        The Company believes that its needs for working capital and capital
expenditures through 1998 and beyond will adequately be met by cash flow and
bank borrowings.


PART II OTHER INFORMATION

ITEM 3.  OTHER INFORMATION

        On September 18, 1998, the Company declared a quarterly dividend on its
Common Stock; the dividend was $0.10 per share. Subject to its continued
profitability and favorable cash flow, the Company intends to continue the
payment of quarterly dividends.
