                 UNITED RENTALS ANNOUNCES REVISED OUTLOOK FOR
                    FOURTH QUARTER 2000 AND FULL YEAR 2001

     GREENWICH, CT, December 18, 2000 - United Rentals, Inc. (NYSE:URI)
announced today that it expects revenues for the fourth quarter ending December
31, 2000 to be approximately $750 million, or 12% below previously expected
levels.  Earnings for the quarter are expected to be approximately $0.40 per
share, compared with analysts' consensus estimates of $0.62 per share. The
Company expects that revenues for the full year 2000 will be approximately $2.92
billion, a 31% increase over the $2.23 billion reported in 1999, and that
earnings per share for the year will be approximately $1.89, a 15% increase over
the $1.65 reported for 1999.

     Bradley Jacobs, chairman and chief executive officer, said, "Our revised
projections for the fourth quarter reflect unusually bad weather in several
parts of the country and the impact of TEA-21 project delays on our traffic
control business. In addition, the slowing economy has reduced demand for
equipment rentals from many of our customers. In our projections for 2001, we
are assuming that the weakness in the economy will accelerate."

     The Company anticipates that rental revenues for 2001 will be approximately
$2.37 billion (up 15% from projected results for 2000), revenues from the sale
of used equipment will be approximately $100 million (down 71%), and sales of
equipment, merchandise and other revenues will be approximately $535 million (up
4%), for total anticipated 2001 revenues of $3.0 billion.  The Company also
projects 2001 earnings per share to be $2.00 to $2.10, a 6 to 11% increase over
projected 2000 results, but below analysts' consensus estimates of $2.53 per
share. The projected decrease in earnings primarily reflects the planned
reduction in used equipment sales.

     Mr. Jacobs continued, "We are responding to the softness in the economy by
reducing our planned capital expenditures for new equipment, decreasing the
amount of used equipment we intend to sell, and taking steps to improve our
overall cost structure. These actions are designed to substantially increase our
free cash flow from operations next year. We anticipate free cash flow from
operations in 2001 will be approximately $390 million, or about $300 million
more than previously expected.

     "Notwithstanding the current economic environment, we remain confident
about the underlying strength of the equipment rental industry. We will continue
to benefit from the longer term trend that has more customers renting equipment
rather than buying."
