               McGrath RentCorp Announces Second Quarter Results;
                      Q2 2004 EPS Increases 26% to $0.49;
                           Company Increases Guidance

     LIVERMORE, Calif.--(BUSINESS WIRE)--Aug. 5, 2004--McGrath RentCorp
(Nasdaq:MGRC), a leading rental provider of modular buildings for classroom and
office space, and test equipment for communications, fiber optic and general
purpose needs, today announced revenues for the quarter ended June 30, 2004 of
$40.8 million, compared to $31.6 million in the second quarter of 2003. The
Company reported net income of $6.1 million, or $0.49 per share, compared to
$4.7 million, or $0.39 per share in second quarter 2003. The Company's improved
quarter over quarter revenues and net income resulted from record rental
revenues at the Company's Mobile Modular division and from contributing revenues
and income related to the Technology Rentals & Services ("TRS") assets acquired.
     The Company completed the purchase of substantially all the assets of TRS,
a division of CIT Group Inc. (NYSE:CIT) on June 2, 2004. Based in Dallas, Texas,
TRS is similar to the Company's existing electronics rental business, RenTelco,
and is one of the leading providers of general purpose and communications test
equipment in North America. Since June 2nd, the electronics business has
operated as TRS-RenTelco and the results for second quarter and first six months
of 2004 include TRS' results since that date. The second quarter 2004 results
also included nonrecurring expenses of $0.6 million, related to the prepayment
of debt, and $0.9 million in severance costs, related to the consolidation of
the Company's RenTelco and TRS operations. These nonrecurring expenses decreased
net income by $0.9 million or $0.07 per share.
     In the second quarter 2004, rental operations revenues for the Mobile
Modular division increased 21% to $22.7 million compared to the same period in
2003 as a result of the continued strength in the California education market,
resulting in a 27% increase of pre-tax income to $9.1 million. For Enviroplex,
the Company's classroom manufacturer, net sales during the quarter declined to
$0.4 million after the elimination of $3.5 million of intercompany sales, with
quarter-end backlog slightly higher than a year ago at $9.6 million. Looking
forward, in third quarter 2004 Mobile Modular is expected to complete a $9.0
million sale project to provide classroom product, manufactured by Enviroplex,
and site related improvements to a California school district scheduled for
completion by September 30, 2004. This sale project is not included in
Enviroplex's quarter-end backlog. At TRS-RenTelco, the Company's electronic test
equipment rental division, rental revenues increased to $8.5 million from $3.0
million in the second quarter of 2003, primarily due to TRS' contribution,
resulting in pre-tax income of $1.2 million after recognition of nonrecurring
severance costs of $0.9 million, as compared to pre-tax income of $0.4 million
in 2003.
     "Mobile Modular had record rental revenues in the second quarter," stated
Dennis Kakures, President & CEO. "Our educational rental business in the
California market continues to see very favorable demand for interim classroom
space to serve local and state bond-funded modernization and reconstruction
projects. We are also progressing well with our entrance in the Florida market,
having launched operations there in the first quarter. Although no rental
revenues were recognized for Florida in the second quarter, we were pleased with
our order activity and will begin to see the rental revenue impact from these
bookings in the third quarter. Given time, we are confident that we can create a
meaningful educational rental business in Florida.
     "To date our electronic test equipment division has made good progress with
its integration efforts in merging TRS and RenTelco. We recently completed the
consolidation of RenTelco inventory and transitioning of employees into the
Dallas-Fort Worth facility. Most importantly, we expect to continue our success
to date in customer and revenue retention throughout the integration period.
Rental revenues for the combined TRS-RenTelco business for the month of June
were $6.2 million. These results are also reflective of continuing improving
test equipment market conditions.
     "As we continue to hone our TRS-RenTelco business platform over the next
few months, we will further refine our operations and overhead cost structures.
By the beginning of the fourth quarter, we should have a much better view of the
earnings horsepower of the new enterprise. With continuing favorable integration
efforts, we expect to realize both the market positioning and financial
objectives in making the acquisition. TRS-RenTelco is being set-up for success
over the long run and I couldn't be more excited about the opportunity."
     Total revenues for the six months ended June 30, 2004, were $70.7 million,
compared to $59.0 million in the same six-month period in 2003. Net income for
the six months ended June 30, 2004, was $11.9 million or $0.96 per share,
compared to net income of $9.6 million, or $0.78 per share, in the prior-year
period.

     SECOND QUARTER 2004 HIGHLIGHTS (AS COMPARED TO SECOND QUARTER 2003)

     --   Rental revenues increased 40% to $25.6 million. Within rental
          revenues, Mobile Modular increased 12% to $17.1 million, driven by
          educational rentals, and RenTelco increased 181% to $8.5 million
          primarily due to TRS's contribution since to June 2, 2004.

     --   Sales revenues decreased 3% to $9.2 million from decreased sales by
          Enviroplex, partially offset by increased equipment sales by Mobile
          Modular and TRS-RenTelco. Lower sales volume, combined with a lower
          overall margin of 23.0% compared to 27.8% in 2003, resulted in a gross
          margin decline of $0.5 million compared to 2003. Sales revenues can
          fluctuate from quarter to quarter depending on customer requirements
          and funding.

     --   Depreciation of rental equipment increased 88% to $5.9 million,
          primarily due to the purchase of TRS rental assets valued at $107.6
          million on June 2, 2004.

     --   Operating cash flow increased 235% to $12.1 million, primarily due to
          the collection of certain accounts receivable of MMMC and Enviroplex,
          and TRS' contribution since June 2, 2004.

     --   Debt increased $124.6 million during the quarter to $168.5 million
          primarily due to the financing of the purchase of TRS' assets. During
          the quarter, the Company opted to prepay the remaining $16.0 million
          of 6.44% senior notes, incurring a $0.6 million prepayment fee. In
          addition, the Company renewed and extended its lines of credit through
          June 2007 to borrow up to $135.0 million, and completed a private
          placement of $60.0 million of 5.08% senior notes to facilitate the TRS
          purchase. Total liabilities to equity ratio increased from 1.19 to 1
          as of March 31, 2004 to 2.08 to 1 as of June 30, 2004, which was
          directly attributable to the TRS purchase. At June 30, 2004, the
          Company, under existing bank lines of credit, had capacity to borrow
          up to an additional $26.5 million.

     --   Dividend rate increased to $0.22 per share for the second quarter
          2004. On an annualized basis, this dividend represents a 2.8% yield on
          the August 4, 2004 close price of $31.33.

     It is suggested that the press release be read in conjunction with the
financial statements and notes thereto included in the Company's latest Form
10-K and Forms 10-Q. You can visit the Company's web site at www.mgrc.com to

     FINANCIAL GUIDANCE

     As a result of the purchase of TRS on June 2, 2004 and recent operating
trends of the business, the Company has increased and broadened its 2004
full-year earnings per share guidance and expects it to be in a range of $2.30
to $2.40 per diluted share. Such a forward-looking statement reflects McGrath
RentCorp's expectations as of August 5, 2004. Results may be materially affected
by many factors, as outlined in the "forward-looking statements" paragraph at
the end of this press release.

     This press release 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. These include, our expectation regarding a $9.0 million
sale by Enviroplex by September 30, 2004, our expectation regarding rental
revenues generated in the third quarter of 2004 from our Florida rental
operations, our expectation regarding meaningful rental business in Florida, our
expectation regarding customer and revenue retention during the integration of
RenTelco and TRS, our expectation regarding having visibility to the earnings
capacity of the TRS-RenTelco business in the fourth quarter of 2004, our
expectation about the TRS-RenTelco realizing market positions and financial
objectives, our annualized dividend yield, and our guidance on per share range
for 2004 full-year earnings. These forward-looking statements are not guarantees
of future performance and involve significant risks and uncertainties. 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,
the condition of the telecommunications industry, new or modified statutory or
regulatory requirements, continuing demand for modular products, timely delivery
and installation of modular products, delays of future sales projects, changing
prices and market conditions, that the acquired TRS assets may not be integrated
successfully and that the TRS transaction may have a negative impact on our
future business or operations, that there may be unanticipated costs of
integrating the acquired assets, that our Florida initiatives may not be
successful or provide meaningful revenue or earnings, and that and that we may
have difficulties in managing a larger, more geographically dispersed
organization. There may be other factors not listed above that could cause
actual results to vary materially from the forward-looking statements described
in this press release.
