                 JONES LANG LASALLE REPORTS STRONG FIRST QUARTER
                   NET INCOME OF $4.6 MILLION, $0.14 PER SHARE

     CHICAGO, April 25 /PRNewswire-FirstCall/ -- Jones Lang LaSalle Incorporated
(NYSE: JLL), the leading global real estate services and money management firm,
today reported net income of $4.6 million, or $0.14 per diluted share of common
stock, for the quarter ended March 31, 2006, compared with a net loss of $8.6
million or $0.27 per share for the first quarter of 2005. Operating income
improved by $19.0 million from a year ago to $8.7 million for the first quarter
of 2006 compared with an operating loss of $10.3 million for the same period in
2005. Due to the seasonal nature of the business, the firm has historically
reported an operating loss in the first quarter; however, in 2006, the firm
benefited from improved results in all segments, the acquisition of Spaulding &
Slye and particularly strong results in the firm's money management business,
LaSalle Investment Management.

     All operating segments achieved strong increases in revenue in the first
quarter of 2006 compared with the same period of the prior year. Revenue for the
first quarter of 2006 was $337 million, an increase of $97 million, or 40
percent in U.S. dollars and 46 percent in local currencies. Spaulding & Slye
contributed approximately eight percent to the year-over-year increase.

     First Quarter 2006 Highlights:

     --   Revenue increased 40 percent with significant growth in all business
          segments
     --   Operating income improved by $19.0 million to $8.7 million
     --   LaSalle Investment Management closed the $3.4 billion CenterPoint
          acquisition

     "Clearly, we are pleased by our first-quarter performance," said Colin
Dyer, Chief Executive Officer of Jones Lang LaSalle. "Our results are the
product of investments throughout our business and improved execution
capabilities across our organization. With the continuing strength of global
real estate markets, we remain confident about our firm's prospects and
performance for the remainder of the year," Dyer added.

     Operating expenses were $328 million for the first quarter of 2006 compared
with $250 million for the same period in 2005, an increase of 31 percent in U.S.
dollars and 37 percent in local currencies. The increase was driven in part by
the acquisition of Spaulding & Slye that was completed on January 3, 2006, as
well as increased compensation costs related to revenue-generation activities.

     Interest expense of $3.2 million for the first quarter of 2006 was
significantly higher than the $0.3 million incurred for the same period in 2005
due to a higher debt balance related to the Spaulding & Slye acquisition as well
as higher interest rates compared with a year ago.



     Included in the 2006 first-quarter results was a $1.2 million, or $0.04
earnings per share, benefit from a cumulative effect adjustment for a change in
accounting for stock-based compensation, which was triggered by the adoption of
the Financial Accounting Standards Board's SFAS No. 123R, "Share-Based Payment,"
effective January 1, 2006. The adjustment represents the after-tax difference
between compensation cost recognized to date using actual forfeitures and the
cost that would have been recognized using estimated forfeitures as required
pursuant to SFAS No. 123R.

     Business Segment First Quarter Performance Highlights

     Investor and Occupier Services

     --   In the Americas, revenue for the first quarter of 2006 was $113
          million, an increase of 53 percent over the same period in 2005. The
          growth is the result of the acquisition of Spaulding & Slye, and
          effective execution within an improving market. Revenue excluding the
          Spaulding & Slye acquisition was up 29 percent.

          In the fourth quarter of 2005, the region reorganized part of its
          operations to focus on "Markets" and "Accounts." The goal of the
          Markets organization is to maximize the firm's local competitive
          position in its targeted markets. The Accounts organization focus is
          on service delivery and strategic advice to multi-geographic corporate
          clients. Capital Markets, Public Institutions, Retail and Regional
          Operations (Canada and Latin America) remain separate Americas product
          lines.

          Revenue was strong in both the Markets and Accounts organizations,
          which include Spaulding & Slye, and in aggregate increased 53 percent
          in the first quarter of 2006 compared with the prior year. Transaction
          revenue was up 78 percent due to a significant number of large
          transactions that closed in the first quarter as compared with the
          prior year, while Management services revenue was up 38 percent due to
          the growth of Project and Development Management services. Regional
          Operations also had a strong first quarter in 2006 compared with the
          prior year, where revenue increased 50 percent in total primarily
          driven by Latin America.

          Capital Markets, recorded as Transaction Services revenue, continued
          its strong performance compared with the prior year, as 2006
          first-quarter revenue increased 42 percent over 2005. Revenue in the
          Americas Hotels business more than doubled, resulting from several
          large transactions closed in the quarter and the impact of the
          acquisition of a select service hotel real estate broker and advisory
          firm completed in the second quarter of 2005.



          Total operating expenses increased 44 percent over the prior year as
          the result of the Spaulding & Slye acquisition and higher compensation
          costs associated with revenue-generating activities.

     --   Europe's revenue for the first quarter of 2006 was $103 million, an
          increase of 22 percent in U.S. dollars and 32 percent in local
          currencies over the same period in 2005. Transaction Services revenue
          was up 34 percent over the prior year, driven by Capital Markets,
          Agency Leasing and Advisory services.

          Geographic contributions to this revenue growth were primarily from
          Germany, France and the United Kingdom. Germany's real estate
          investment market continued to improve with an increase in
          international capital flowing into the country. Revenue in Germany for
          the first quarter of 2006 grew 43 percent in U.S. dollars and 55
          percent in local currencies compared with the same period of the prior
          year. The French business was up significantly as revenue increased
          more than 100 percent in both U.S. dollars and local currencies. The
          English business continued its momentum, with revenue up 14 percent in
          U.S. dollars and 24 percent in local currencies.

          Operating expenses increased by 16 percent in U.S. dollars for the
          first quarter year over year and 26 percent in local currencies. The
          increase was primarily due to higher incentive compensation resulting
          from improved revenue performance.

     --   Revenue for the Asia Pacific region was $58 million for the first
          quarter of 2006, an increase of 18 percent in U.S. dollars and 22
          percent in local currencies over the prior year. The growth in revenue
          in U.S. dollars came from both Transaction Services revenue, which
          grew 15 percent, and from Management Services revenue, which grew 19
          percent due to the expansion of property and facility management
          services. The growth markets of China, Japan, Korea and India
          experienced healthy increases in revenue in the first quarter of 2006
          compared with the prior year. Revenue in total for these markets
          increased 38 percent in local currencies, and 33 percent in U.S.
          dollars, led by China. The core markets of Hong Kong and Australia
          continued their momentum from 2005 with strong performance across all
          business lines, with first-quarter 2006 revenue increasing 21 percent
          in U.S. dollars and 24 percent in local currencies over the prior
          year.



          Year-over-year operating expenses for the Asia Pacific region for the
          first quarter of 2006 increased 15 percent in U.S. dollars, 19 percent
          in local currencies, primarily as a result of the firm's investment in
          people and technology infrastructure in the region. Market expansion
          with the opening of new offices across the region also contributed to
          the increase in operating expenses.

          Operating income in the first quarter on a comparable basis improved
          by $2.7 million from the prior year, as 2005 included the benefit of a
          credit of $1.6 million received from a litigation settlement.

     LaSalle Investment Management

     --   LaSalle Investment Management's first-quarter revenue in 2006 was $62
          million, an increase of 95 percent over the 2005 first quarter. During
          the first quarter of 2006, the firm completed the acquisition of
          CenterPoint Properties Trust on behalf of a joint venture with a key
          client in which LaSalle Investment Management has a minority interest.
          The acquisition resulted in both a large one-time fee recorded as
          Transaction revenue, as well as on-going Advisory Fees.

          Advisory Fees, which provide annuity revenue, were $38 million for the
          first quarter of 2006, compared with $28 million in 2005, an increase
          of 35 percent over the prior year. The growth in Advisory Fees is
          driven by the continued strong growth in assets under management.

          For the first quarter of 2006, incentive fees were $13.5 million, an
          increase of $11.2 million over the prior year. These fees were earned
          on the final disposition of assets, completing the liquidation of two
          funds. Incentive fees vary significantly from period to period and are
          determined by both the performance of the underlying funds'
          investments and the contractual timing of the measurement period with
          clients. In the second quarter of 2006, the firm is contractually due
          a significant gross incentive fee of approximately $60 million from a
          single client, which will contribute a net operating margin, after the
          deduction of all related expenses including compensation, of
          approximately 40 percent. The fee is larger than usual due to the
          eight-year contractual measurement period, as well as outstanding
          performance execution by the firm. The actual amount of the fee will
          not be finalized until after the end of the second quarter and may
          increase or decrease based on required external valuations.



          LaSalle Investment Management's assets under management grew to $34
          billion at the end of the first quarter of 2006 including the
          CenterPoint acquisition. Total investments made during the first
          quarter of 2006 on behalf of clients, including the CenterPoint
          acquisition, were $4.9 billion.

     Summary

     The firm experienced strong growth across all segments in the first
quarter, the result of effective execution, favorable market conditions and
performance resulting from the firm's strategic initiatives. These initiatives
include the completion of acquisitions in the Americas and LaSalle Investment
Management, the organizational change in the Americas and strategic investments
made in 2005. As the firm also continues to benefit from its globally diverse
business platform and the continued strength of the real estate markets, it is
well-positioned for the remainder of the year.

                            Financial Statement Notes

1.   EBITDA represents earnings before interest expense, net of interest income,
     income taxes, depreciation and amortization. Although EBITDA is a non-GAAP
     financial measure, it is used extensively by management and is useful to
     investors as one of the primary metrics for evaluating operating
     performance and liquidity. The firm believes that an increase in EBITDA is
     an indicator of improved ability to service existing debt, to sustain
     potential future increases in debt and to satisfy capital requirements.
     EBITDA is also used in the calculations of certain covenants related to the
     firm's revolving credit facility. However, EBITDA should not be considered
     as an alternative either to net income or net cash provided by operating
     activities, both of which are determined in accordance with GAAP. Because
     EBITDA is not calculated under GAAP, the firm's EBITDA may not be
     comparable to similarly titled measures used by other companies.

     2.   Net debt represents the aggregate of 'Short-term borrowings' and
          'Credit facilities,' less 'Cash and cash equivalents.'

     3.   For purposes of segment operating results, the allocation of
          restructuring charges (credits) to our segments has been determined to
          not be meaningful to investors. Additionally, the performance of
          segment results has been evaluated without these charges (credits)
          being allocated.

     4.   The consolidated statements of cash flows are presented in summarized
          form. For complete consolidated statements of cash flows, please refer
          to the firm's Quarterly Report on Form 10-Q for the quarter ended
          March 31, 2006, to be filed with the Securities and Exchange
          Commission shortly.

     5.   Beginning in 2006, we have renamed 'Implementation Services' to
          'Transaction Services.'
