                 JONES LANG LASALLE REPORTS RECORD EARNINGS;
               2005 NET INCOME OF $104 MILLION, $3.12 PER SHARE

    CHICAGO, Jan. 31 /PRNewswire-FirstCall/ -- Jones Lang LaSalle Incorporated
(NYSE: JLL), the leading global real estate services and money management firm,
today reported record net income of $104 million, or $3.12 per diluted share of
common stock, for the year ended December 31, 2005. The prior year's net income
was $64 million, or $1.96 per diluted share. Included in the 2004 figures was a
$0.26 per share expense related to the redemption of the firm's euro 165 million
Senior Notes. Also included in the 2004 results were restructuring charges of
$5.4 million, or $0.12 per share, compared with $1.4 million or $0.03 per share
recorded in 2005. Revenues for the full year 2005 were $1.39 billion, an
increase of 19 percent from the prior year that resulted from growth in all
operating segments. Operating income for the current year was $132 million
compared with $90 million for the prior year, which represented an increase of
47 percent.

    For the fourth quarter of 2005, net income was $67 million, or $1.99 per
diluted share, compared with net income of $50 million, or $1.52 per diluted
share, for the same period in 2004. Restructuring charges of $4.3 million, or
$0.10 per share, were included in the fourth quarter results of the prior year
compared with $0.9 million, or $0.02 per share, recorded in the same period of
this year. Revenue for the fourth quarter of 2005 was $499 million, an increase
of 21 percent from 2004, with all segments showing healthy increases. Operating
income for the fourth quarter increased 43 percent to $86 million from $60
million in the prior year.

     Full Year 2005 Highlights:

     -- Revenues increased 19 percent with growth in all business segments

     -- Operating income increased 47 percent driven by LaSalle Investment
        Management and the Asia Pacific region

     -- Net income increased 61 percent

     -- LaSalle Investment Management completed record capital raise, $30
        billion of assets currently under management

    "We are extremely pleased with our record 2005 performance," said Colin
Dyer, the firm's Chief Executive Officer. "Our results reflect both the quality
of the products and services we deliver to clients and the commitment and
client-service focus of our people. Working from this position of strength, we
will continue to focus on growth in all our regions and in each of our major
service lines," Dyer added.

    Operating expenses were $413 million for the fourth quarter of 2005 compared
with $353 million for the same period in 2004, an increase of 17 percent in U.S.
dollars and 22 percent in local currencies. For the full year, operating
expenses were $1.26 billion in 2005 and $1.08 billion in 2004, an increase of 17
percent in both U.S. dollars and local currencies from the prior year. The
increase was driven by increases in compensation costs related to revenue
generation activities in addition to strategic investments the firm made to
strengthen positions in key local and regional markets and extend global service
lines.

    Prior to the third quarter of 2005, non-recurring and restructuring charges
were presented as a separate line item in the consolidated statements of
operations. Beginning in the third quarter of 2005, the firm refined its
presentation policy to separately present only restructuring charges, which are
costs to exit operations. The final payment from the litigation settlement of
the 2003 abandonment of a property management software system in Asia Pacific of
$0.6 million was received in the fourth quarter of 2005 and was recorded as a
credit to "Operating, administrative and other" expenses. The settlement amounts
received during the first half of 2005 and for the full year 2004 of $1.6
million and $2.8 million, respectively, were reclassified in the third quarter
from "non-recurring and restructuring" to conform to the current presentation.
Such reclassification had no impact on consolidated total operating expenses or
operating income.



    The current year's interest expense for the full year 2005 was $4.0 million
compared with $20.9 million for 2004. The prior year's interest expense included
an $11.6 million expense related to the redemption of the Senior Notes. The
improved interest expense in 2005 was a result of significantly lower debt
levels throughout the year and a lower effective interest rate compared with
2004. In 2005, the firm repurchased approximately 1.6 million shares of its
common stock.

     Business Segment Fourth Quarter and Full Year Performance Highlights

     Investor and Occupier Services

     -- The Americas region continued its momentum through the end of the year.
        Revenues for the fourth quarter of 2005 were $164 million, an increase
        of 15 percent over 2004, and $435 million for the full year, an increase
        of 17 percent over the prior year. Management Services revenues
        increased 27 percent for the quarter, 23 percent for the full year,
        while Implementation Services grew six percent for the quarter and 11
        percent for the year compared with 2004. Capital Markets, recorded as
        Implementation Services revenues, continued its strong performance
        compared with the prior year, with full-year revenues increasing 67
        percent over 2004. The Real Estate Occupier Services products, marketed
        as Corporate Solutions, continued to generate at least 50 percent of the
        region's revenues for the full year. Compared with 2004, Corporate
        Solutions revenues grew 19 percent for the quarter and 15 percent for
        the year. Within Corporate Solutions, Project and Development Services
        revenues increased 18 percent for the quarter and 26 percent for the
        full year, while Public Institutions revenues increased 86 percent for
        the quarter and 51 percent for the full year. Partially offsetting these
        increases was Tenant Representation, where lower existing client
        activity in the U.S. resulted in a revenue decline. The Tenant
        Representation business did, however, expand nine of its top 60 clients
        into multi-regional accounts where activity was reported in the other
        geographic segments and therefore benefited the firm's consolidated
        results. The Americas Hotels business had a solid fourth quarter and
        full year, benefiting from its leadership position in a strong market as
        well as the acquisition during the year of ThompsonCalhounFair Hotel
        Brokerage, a hotel real estate broker and advisory firm.

        Total operating expenses increased 22 percent for the quarter and 21
        percent for the full year compared with 2004. The increase reflects
        strategic investments made to service new client wins and to expand
        market coverage in both Agency Leasing and Capital Markets. In addition,
        incentive compensation expenses increased as a result of the growth in
        revenue-supporting staff and the underlying mix of business profit
        contribution.

        As previously announced, on January 3, 2006, the Americas completed its
        merger transaction with Spaulding & Slye, a privately held real estate
        services and investment company with offices in Boston and Washington,
        DC.



     -- Europe's year-over-year revenue growth was driven by strong performances
        in Capital Markets, Agency Leasing and Advisory, primarily in Germany,
        United Kingdom and Russia. The region's revenues for the fourth quarter
        of 2005 were $177 million, an increase of 17 percent in U.S. dollars and
        28 percent in local currencies over 2004. For the full year, revenues
        were $493 million, an increase of 11 percent in U.S. dollars and 13
        percent in local currencies over the prior year. Germany had significant
        growth compared to the prior year as a result of an improving investment
        market that is increasingly attracting international capital. Revenues
        in Germany grew 75 percent in U.S. dollars for the quarter and 50
        percent for the full year compared with the prior year. The English
        business continued its upward trend, with revenues up six percent in
        U.S. dollars and eight percent in local currencies driven mainly by
        Capital Markets. Approximately 75 percent of the Capital Markets
        business involved cross-border transactions as a result of the firm's
        strong global platform, and the client base. The Corporate Finance
        business, which is included in Capital Markets, also achieved
        significant growth in revenues for the full year over the prior year,
        where the focus continues to be on developing structured financing
        activities and private investor products. Russia had significant growth
        in its business in 2005 compared with 2004. Revenues in Russia for the
        fourth quarter increased over 100 percent and increased over 50 percent
        for the full year in U.S. dollars compared with the prior year. Revenues
        for the full year 2005 from the French business declined modestly
        compared with 2004, a year in which several large Capital Markets and
        Agency Leasing transactions were recorded.

        Operating expenses increased by 11 percent in U.S. dollars for the
        quarter year over year and 20 percent in local currencies, and grew 10
        percent in U.S. dollars and 12 percent in local currencies on a
        full-year basis. The increase was primarily due to incentive
        compensation being higher due to the improved revenue and profit
        performance.

     -- Revenues for the Asia Pacific region were $92 million for the fourth
        quarter, an increase of 26 percent in U.S. dollars and 29 percent in
        local currencies from the prior year. On a full-year basis, revenues
        were $273 million, an increase of 23 and 21 percent in U.S. dollars and
        local currencies, respectively. Growth for the quarter and year to date
        in U.S. dollars came from both Implementation Services revenues, which
        grew 27 and 25 percent, respectively, and Management Services revenues,
        which grew 25 and 22 percent, respectively. Revenues from the growth
        markets of China and Japan increased over 60 percent in U.S. dollars for
        the full year 2005 over the prior year. The core markets of Hong Kong,
        Singapore and Australia continued the momentum across all business lines
        with full-year 2005 revenues increasing 15 percent in U.S. dollars over
        the prior year. The Asian Hotels business also had another very strong
        quarter as a result of increased transaction volume and increased market
        share.

        Total operating expenses for the Asia Pacific region for the fourth
        quarter of 2005 increased 20 percent in U.S. dollars, 22 percent in
        local currencies, over the prior year. On a full-year basis, operating
        expenses were up 18 percent in U.S. dollars and 16 percent in local
        currencies. Operating expenses include the reclassified benefits from
        "non-recurring and restructuring" expenses, which are excluded from
        segment reporting. Continued investment in people and technology in the
        growth markets, as well as new office openings, contributed to the
        increase in operating expenses. As a result of expansion during 2005,
        the firm operates in 16 markets in China and in six markets in India.



     LaSalle Investment Management

     -- LaSalle Investment Management's fourth quarter revenues in 2005 were $72
        million, an increase of 34 percent in U.S. dollars and 38 percent in
        local currencies. For the full year, revenues grew to $203 million, up
        35 percent in both U.S. dollars and local currencies over the prior
        year. Incentive fees, resulting from strong performance of clients'
        investments and the continued growth of the annuity-based business,
        drove the increase in revenues.

        In 2005, fourth quarter incentive fees were $26 million, an increase of
        $11 million over the prior year, and $43 million for the full year in
        2005, an increase of $23 million over 2004. Incentive fees can vary
        significantly from period to period due to both the performance of the
        underlying funds' investments and the contractual timing of the
        measurement period with different clients. For example, in 2005,
        incentive fees of $2 million or greater were earned from eight separate
        clients, double the number from the previous year.

        The continued focus on the growth in annuity revenues led to a fourth
        quarter increase in Advisory fees of 29 percent over 2004 and an
        increase of 26 percent over 2004 for the full year. Advisory fees, which
        were $35 million for the fourth quarter of 2005 and $128 million for the
        full year in 2005, accounted for nearly two-thirds of LaSalle Investment
        Management's full-year revenues.

        Equity earnings were down for the full year, from $17 million to $12
        million, as several larger transactions closed in 2004.

        LaSalle Investment Management raised over $3 billion of equity during
        2005, as it launched six new private equity funds and secured nine
        global securities mandates. Investments made on behalf of clients in
        2005 were approximately $6 billion and assets under management grew to
        $30 billion, a 24 percent increase over the prior year.

    Summary

    As the leading global real estate services provider and money manager,
during 2005 the firm benefited from favorable market conditions and capitalized
on the growth in cross-border capital flows into real estate. The firm's
corporate clients continued increasingly to outsource their real estate
management and to rely on the firm's advice and execution to manage their global
real estate needs. In addition, LaSalle Investment Management's strong financial
results were a reflection of its outstanding track record and its research-based
approach that delivered performance for its clients. These favorable trends,
combined with the overall positive environment for commercial real estate, are
expected to continue into 2006.

     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.

     Below is a reconciliation of net income to EBITDA (in thousands):

                                                Years Ended December 31,
                                               -------------------------
                                                  2005            2004

2.   Effective the fourth quarter of 2004, 'Equity in earnings from
     unconsolidated ventures' has been reclassified, for all periods presented
     on the Consolidated Statement of Earnings, from 'Revenue' to be presented
     as a separate line item between 'Total interest and other costs' and
     'Income before provision for income taxes,' in accordance with Rule 5-03 of
     Regulation S-X. As a result, 'Operating income' has been adjusted for the
     comparative year. Since equity earnings are an integral part of the money
     management business, equity earnings have been included within 'Revenue' in
     segment operating results for discussion purposes only.

3.   Net debt represents the aggregate of 'Short-term borrowings,' 'Credit
     facilities,' and '9 percent Senior Euro Notes' less 'Cash and cash
     equivalents.'

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

5.   The consolidated statements of cash flows are presented in summarized form.
     For complete consolidated statements of cash flows, please refer to the
     firm's Annual Report on Form 10-K for the year ended December 31, 2005, to
     be filed with the Securities and Exchange Commission shortly.

6.   Net income available to common shareholders is net income less dividends
     declared on unvested common shares of $0.4 million.
