CB Richard Ellis Reports Operating Results for First-Quarter 2001

EL SEGUNDO, Calif. - CB Richard Ellis (NYSE:CBG) today reported an increase in
revenue over the prior year and positive operating results from its North
America operations. These results were mitigated by a softening of revenue in
Asia and in Europe.

Revenue for the first quarter was $272.5 million, a 4% improvement over revenue
generated during the first quarter of last year. This increase in revenue was
the result of higher lease revenue, improved property and facility management
fees, strong results by the valuation unit, and solid revenue growth of the
mortgage banking unit.

These revenue improvements were primarily achieved in the North America
Division, partially mitigated by softening of revenue in Asia and Europe.

EBITDA for the quarter was $14.0 million, as compared to a robust $19.8 million
reported during the same period last year. Due to the seasonal nature of its
operations, the company typically reports small losses or break-even results
during its first calendar quarter. The company recorded a net loss for the first
quarter of $2.8 million, which represents a net loss of $0.13 per share.
Comparatively, during the first quarter of 2000, the company reported break-even
net income.

Operating results during the first quarter of 2001 and 2000 were impacted by the
occurrence of non-recurring sales of business operations. The company recognized

gains from one-time sales, net of related expenses, of $5.4 million during the
first quarter of 2001 as compared to $4.7 million during the first quarter of
2000.

Additionally, the company disposed of other business operations during 2000,
which had generated approximately $1.8 million in revenues during the first
quarter of 2000, with no such revenue during 2001.

Chief Executive Officer Ray Wirta commented: "We are pleased with the revenue
growth of our business, particularly in North America. Despite economic softness
in several of our key markets in North America and internationally, each of our
business segments continued to generate revenue growth. A softening economy in
the United States has been evidenced by slower job growth, resulting in a
predictable negative impact on real estate activity by corporate clients.

"Our Transaction Management group produced quarter-over-quarter revenue growth
of 1%, led by the Corporate Services business unit, which posted a 23%
improvement in revenues. We believe that this affirms our strategy to focus
resources to help our corporate clients manage their real estate operations more
effectively."

Wirta noted: "Led by our mortgage banking group, the Financial Services
businesses continued to provide profitable growth, generating 22% growth in
revenue and 25% growth in EBITDA from recurring operations. Excluding non-
recurring items and adjusted for the effect of business disposals, Management
Services generated 6% growth in revenue from recurring operations.

"The growth in revenues was driven by our North America operations, which
posted a 7% increase in revenue during the first quarter of 2001 as compared to
the prior year. Asia operations were adversely affected by a reduction in the
level of U.S. corporate expansion and by the recent dispute between China and
the U.S.

"Additionally, our European operations did not perform at the same level as the
prior year. We are closely monitoring the situation in both Asia and Europe, and
have already taken steps to reduce our operating expenses.

"Although our North American results were positive, certain local regional
economies in the U.S. are experiencing an economic slowdown. This is
particularly evident in the Western United States, which we equate the economic
softness to the pronounced decline in the technology and telecommunication
sectors.

"We continue to believe in the fundamentals for our business for the long term;
however, if the softness in the U.S. economy continues, it will impact our
revenue growth for the balance of the year.

"Our business model allows for the flexibility to reduce expenses in response
to declining revenues. We have contingency plans in place to reduce our costs
should revenue begin to decline and have a history of successfully implementing
such programs."

Quarterly Segment Performance

The company reports its operations under three core business segments:

    .  Transaction Management. Transaction Management generated $180.0 million
       of revenue in the first quarter, up 1% over the same period last year.
       The transaction management revenues improved in North America by 5% over
       the comparable period of last year. This was partially offset by softness
       in revenues in Europe and Asia. The Corporate Services business unit
       generated $29.9 million of revenue, an improvement of 23% over the $24.4
       million of revenue during the same period of last year. The Investment
       Properties unit posted revenue of $38.0 million during the first quarter
       of 2001, which represents quarter-over-quarter growth of 11%. Transaction
       Management EBITDA for the first quarter was $2.0 million, a $7.6 million
       decrease from last year. Higher compensation costs relating to the
       expansion and retention of the sales force in North America, combined
       with the planned expansion of international operations, resulted in
       expenses being at a higher level than the prior year.

    .  Financial Services. Financial Services generated $55.9 million of revenue
       during the first quarter, up 35% over the first quarter of last year.
       Revenue improved in the three major business lines that compose this
       segment: valuation, mortgage and investment management. EBITDA rose to
       $10.1 million during the first quarter, an improvement of $6.3 million,
       compared to the same period last year. Additionally, contributing to the
       first-quarter 2001 results was a one-time gain, net of related expenses,
       of $5.6 million resulting from the sale of a managed fund in the
       investment management business. Financial Services was a more significant
       part of the company's operating performance in the first quarter of 2001,
       reflecting the company's strategy to concentrate on higher-margin
       business lines and improved market conditions for the mortgage and
       valuation business lines. Excluding non-recurring items, revenue from
       Financial Services represented approximately 19% of total revenues during
       the first quarter of 2001, as compared to 16% during the first quarter of
       2000.

    .  Management Services. Management Services' revenue for the first quarter
       totaled $36.6 million as compared to $34.5 million of recurring revenue
       for the first quarter of 2000. Although the company reported revenue of
       $41.1 million from this segment during the first quarter of 2000, such
       revenue included $6.5 million of non-recurring items. During the first
       quarter of 2000, the company recorded a one-time gain of $4.7 million
       from the sale of a Telecommunication business. Additionally, during the
       fourth quarter of 2000, the company sold its Strategic HR business. The
       Strategic HR business generated approximately $1.8 million of revenue
       during the first quarter of 2000. Management Services' EBITDA for the
       quarter ended March 31, 2001, totaled $1.9 million, an improvement of 15%
       over recurring EBITDA for the prior year. The company reported EBITDA of
       $6.4 million during the first quarter of 2000; however, this includes the
       $4.8 million of non-recurring EBITDA related to the sale of the
       Telecommunication and Strategic HR businesses.
