                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 30, 1998

NOTE 1.   CONSOLIDATED FINANCIAL INFORMATION

     The consolidated financial information for the six months ended June 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 six months ended June
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.

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

THREE AND SIX MONTHS ENDED JUNE 30, 1998 AND 1997

     Rental revenues for the three and six months ended June 30, 1998 increased
$2,596,165 (18%) and $5,250,057 (18%), respectively, over the comparative
periods in 1997. Mobile Modular Management Corporation ("MMMC") contributed
$3,552,623 (68%) and electronics contributed $1,697,434 (32%) of the six-month
increase. The significant rental revenue increase by MMMC resulted from the
large quantities of equipment shipped to schools in the latter part of 1997.
Average utilization for electronics during the first six months increased from
53.9% in 1997 to 55.8% in 1998 and declined for modulars from 79.0% in 1997 to
75.8% in 1998. Modular utilization declined primarily due to a substantial
increase in inventory from the addition of new classrooms for the 1998 school
year. Modular utilization excluding new equipment inventory was 82.2% compared
to 81.0% as of June 30, 1998 and 1997, respectively, with an additional
$17,643,000 of modular equipment on rent as of June 30, 1998 compared to a year
earlier. 

     Rental related services revenues for the three and six months ended June
30, 1998 increased $594,136 (28%) and $176,003 (4%), respectively, as compared
to the same periods in 1997. Gross margins increased from 34% to 35% in 1998 for
the comparative six-month period.

     Sales for the three and six months ended June 30, 1998 declined $3,111,286
(19%) and $4,760,636 (18%), 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 15% and 11%, respectively, over the 1997
comparative six-month period which partially offset MMMC's expected decline in
new classroom sales. (See 1997 Form 10K Management Discussion and Analysis for
Fiscal Years 1997 and 1996.) Gross margin on sales improved for the six-month
period from 32% in 1997 to 34% in 1998. 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 six months ended June
30, 1998 increased $345,900 (10%) and $769,150 (11%) 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 23% between June
30, 1997 and June 30, 1998. Other direct costs of rental operations for the
three and six months ended June 30, 1998 increased $1,331,388 (60%) and
$1,714,933 (35%) over the comparative periods in 1997 due to increased
maintenance costs of the modular fleet and higher amortization of lease expenses
included in the rental rate.

     Selling and administrative expenses for the three and six months ended June
30, 1998 increased $150,079 (4%) and $497,178 (7%), respectively, compared to
the same periods in 1997 primarily due to higher personnel and benefit costs.
Personnel and benefit costs increased $433,225 over the comparative six-month
period in 1997 resulting from additional staff for sales and support, including
the addition of electronics sales people on the East Coast, and higher health
insurance costs.

     Interest expense for the three and six months ended June 30, 1998 increased
$593,438 (60%) and $1,171,399 (63%) over the comparative periods in 1997 as a
result of higher average borrowing levels in 1998. The debt increase was
primarily due to rental equipment purchases made during 1997.

     Net income for the three and six months ended June 30, 1998 decreased
slightly as compared to the comparative periods in 1997 and amounted to
$5,974,336 and $10,942,035, respectively. Earnings per share increased slightly
for the three and six-month periods in 1998 to $0.42 per share and $0.77 per
share, respectively, on fewer shares outstanding.

LIQUIDITY AND CAPITAL RESOURCES

     The Company had total liabilities to equity ratio of 1.74 to 1 and 1.56 to
1 as of June 30, 1998 and December 31, 1997, respectively. The debt (notes
payable) to equity ratio was 1.07 to 1 and 0.83 to 1 as of June 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 August 7, 1998, the Company has
repurchased 519,550 shares of its outstanding common stock for an aggregate
purchase price of $10,424,093 (or an average price of $20.06 per share). As of
August 7, 1998, 919,900 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 June 11, 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.
