     Jones Lang LaSalle Reports Solid Revenue Growth in First Quarter Results

     CHICAGO, April 27 /PRNewswire-FirstCall/ -- Jones Lang LaSalle Incorporated
(NYSE: JLL), the leading global real estate services and money management firm,
today reported a net loss of $8.6 million, or $0.27 per share of common stock,
for the quarter ended March 31, 2005. The loss is consistent both with the
seasonal nature of the business and the planned increases in the investments the
firm has made in people and infrastructure to support future growth. The net
loss for the same period in the prior year was $6.1 million, or $0.20 per share.

     Revenues increased 9 percent in U.S. dollars, 6 percent in local
currencies, to $240.2 million for the first quarter 2005 compared to $220.7
million for the same period in 2004. Revenues for LaSalle Investment Management,
the firm's money management business, contributed a 10 percent year-over-year
increase in U.S. dollars, 7 percent in local currencies, leading to an increase
in operating income from the prior year of 35 percent in U.S. dollars and 30
percent in local currencies. Strong performance in both Corporate Property
Services ("CPS") and Project and Development Services ("PDS") across all
Investor and Occupier Services ("IOS") businesses also contributed to the
revenue improvement. The continued economic and business improvement,
principally in the Americas and Asia Pacific, has had a positive impact on the
increase in revenues.

     First Quarter Highlights:

     --  Revenues increased 9 percent in U.S. dollars and 6 percent in local
         currencies
     --  Operating income increased 35 percent for LaSalle Investment
         Management
     --  Net debt decreased $69 million from first quarter of 2004

     "Our strong revenues in the first quarter demonstrate how our people
continue to take advantage of generally healthy market conditions to deliver
value to clients around the world," said Colin Dyer, the firm's Chief Executive
Officer. "While a first-quarter loss is typical for our business -- with most of
our profits coming later in the year -- it also reflects the operational
investments we are making to strengthen our presence in key markets, extend our
global service lines and improve our client-service delivery capabilities," Dyer
added.



     Operating expenses were $250.5 million for first quarter 2005 and $227.4
million for the same period in 2004, an increase of 10 percent in U.S. dollars,
8 percent in local currencies. The increase includes added staffing to service
client and business wins, particularly in the IOS and LaSalle Investment
Management segments in Asia Pacific, as well as the impact of strategic
investments, such as the Quartararo & Associates acquisition made in the
Americas during the third quarter of 2004. Offsetting the 2005 operating
expenses is a $1.6 million pre-tax benefit from the agreed settlement of
litigation relating to the 2003 abandonment of a property management software
system in the Australian business. Through March 31, 2005, $5.9 million of the
total settlement of $7.3 million has been received and recognized.

     Interest expense of $0.3 million for the quarter was significantly lower
than the $3.8 million incurred in the first quarter of 2004, reflecting the
continued pay-down of debt and the early redemption of the 9 percent Senior
Notes in June 2004. The first quarter traditionally represents the firm's peak
borrowing requirements in the year as annual bonuses are paid. During the first
quarter of 2005, approximately 340,000 shares of common stock were repurchased
for $15.2 million. Net debt as of March 31, 2005 was $121 million, a $69 million
reduction from the prior year. The estimated effective tax rate for the first
quarter of 2005 was 25.4 percent, as compared to 28.0 percent for the same
period last year. This rate improvement, based on disciplined global tax
planning, will favorably affect the full year's projected results, but when
applied to the seasonal net loss it negatively impacts the first quarter
year-over-year results by $0.3 million.

     Business Segment First Quarter Highlights

     Investor and Occupier Services

     --   The Americas region continued the momentum of its strong 2004 finish
          into the first quarter of 2005, reporting a 16 percent year-over-year
          increase in revenues. Management services revenues were the main
          driver of the growth, increasing 18 percent for the quarter, while the
          transaction revenues grew 13 percent compared to 2004. The strategic
          acquisition of Quartararo & Associates, now part of the PDS business
          serving the greater New York area, contributed to the firm's
          performance as demonstrated by the revenue increase of 20 percent from
          that business in the Americas overall. The region also had strong
          performance in Public Institutions and its facility management
          business, CPS.

          Total operating expenses increased 22 percent for the quarter compared
          to 2004, with the increase reflecting higher staffing levels necessary
          to service new client wins as well as strategic hiring to expand
          market coverage in both leasing and capital markets.

     --   The European region's revenues for the first quarter of 2005 declined
          5 percent in U.S. dollars, 9 percent in local currencies, as a result
          of delays in the closing of certain anticipated transactions into the
          second quarter. Certain fourth-quarter 2004 restructuring efforts,
          which included realigning resources and further consolidating the



          German business, together with hiring a new leader for that country,
          have started to have a positive impact in 2005. As a result, Germany
          showed early signs of improvement with an increase in revenues as
          compared to 2004. Overall, the European business is expected to have a
          stronger second quarter and anticipates achieving results that are
          above those of the prior year at second quarter end.

          Operating expenses continue to be aggressively managed, with a
          decrease from the prior year of 3 percent in local currencies,
          representing an increase of 1 percent from the prior year in U.S.
          dollars.

     --   Performance for the Asia Pacific region continued to confirm the
          commitment the firm has made to that region over the past few years,
          with revenues increasing more than 22 percent in U.S. dollars and 20
          percent in local currencies. The main growth was in transaction
          activity, which increased over 30 percent in U.S. dollars from 2004.
          Management services revenues increased 13 percent in U.S. dollars over
          the prior year. The growth markets of China and Japan continued the
          momentum from the end of 2004, with revenues increasing 58 and 33
          percent, respectively, in local currencies, for the first quarter of
          2005 compared to the same period in 2004. The firm's leading market
          position in Hong Kong produced another strong quarter with revenues
          increasing over 25 percent in local currency over the prior year. The
          Asian Hotels business had another robust quarter in the core market of
          Australia, where revenues more than tripled from 2004.

          Total operating expenses for the first quarter of 2005 increased 17
          percent in U.S. dollars, 15 percent in local currencies over the prior
          year, reflecting continued investment in people and technology in the
          growth markets of China, India and Japan. Additionally, new offices
          were opened in Macau and Osaka.

     LaSalle Investment Management

     --   Revenues for first-quarter 2005 were up 10 percent in U.S. dollars, 7
          percent in local currencies, over the prior year as the business
          continued to emphasize growth in its annuity revenues from advisory
          fees, which increased 10 percent from 2004 in U.S. dollars. First
          quarter transaction fees increased 23 percent over the prior year as
          capital flows into real estate remained strong. The business
          recognized total first quarter incentive fees of $2.3 million, with
          asset sales and portfolio performance producing strong investment
          returns for the firm's clients. Impairment charges were taken against
          two funds in the firm's co-investment portfolio resulting in a decline
          in equity earnings from 2004. For the year, the firm is expecting
          solid revenue contributions from its co-investment portfolio as
          additional assets are sold. The overall revenue strength resulted in
          operating income improvements of over 35 percent in U.S. dollars, 30
          percent in local currencies, from 2004.



          Strong response from investors to product offerings continues, and the
          business is ahead of its expected capital-raising activities with
          respect to funds planned for launch during 2005. In total, capital
          investments exceeded expectations in the first quarter of 2005.
          Specifically, capital investments in Asia Pacific funds during the
          first quarter of 2005 almost matched the levels seen for all of 2004.

     Outlook
     Consistent with prior years, the firm is not providing full-year earnings
guidance for the remainder of 2005 due to both the transactional nature of a
large part of the firm's service offerings as well as the seasonal nature of the
business. This seasonality back-ends the majority of the firm's profits into the
fourth quarter; it is therefore premature to predict the remaining 2005
operating environment at this time. The European business is expected to have a
stronger second quarter and anticipates an increase in revenues for the first
half of the year over the prior-year period. Overall, the firm continues to
emphasize growth in its annuity revenues as well as enhancement of the profit
margins in all its product and service lines. The firm has and will continue to
increase its strategic growth investments in 2005 to areas such as China, and to
its global Corporate Solutions and global Capital Markets service offerings. The
current economic environment appears stable globally for real estate services,
with continued strong growth expected in the Asia Pacific region.

                            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.

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

     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 Investment Management business,
         equity earnings has 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% Senior Euro Notes' less 'Cash and cash
         equivalents'.

     4.  For purposes of segment operating results, the allocation of the
         non-recurring charges (credits) to 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 Quarterly Report on Form 10-Q for the period
         ended March 31, 2005, to be filed with the Securities and Exchange
         Commission shortly.
