The accompanying notes to consolidated condensed financial
statements are an integral part of these statements.

OMNICOM GROUP INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

1. We have prepared the consolidated condensed interim financial statements
included herein without audit pursuant to Securities and Exchange
Commission rules. Certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally
accepted accounting principles ("GAAP") have been condensed or omitted
pursuant to these rules.

2. The accompanying financial statements reflect all adjustments, consisting
of normally recurring accruals, which in the opinion of management are
necessary for a fair presentation, in all material respects, of the
information contained therein. Certain amounts in prior periods have been
reclassified to conform them to the quarter end March 31,ended June 30, 2005
presentation. These statements should be read in conjunction with the
consolidated financial statements and related notes included in our annual
report on Form 10-K for the year ended December 31, 2004.

3. Results of operations for interim periods are not necessarily indicative
of annual results.

4. Basic earnings per share is based upon the weighted average number of
common shares outstanding during the period. Diluted earnings per share is
based on the above, plus, if dilutive, common share equivalents which
include outstanding options and restricted shares. For purposes of
computing diluted earnings per share, 1,161,0001,346,000 and 832,0001,314,000 common share
equivalents were assumed to be outstanding for the three months ended March 31,June
30, 2005 and 2004, respectively, and 1,436,000 and 1,443,000 common share
equivalents were assumed to be outstanding for the six months ended June
30, 2005 and 2004, respectively. For the three months ended June 30, 2005
and 2004, respectively, 4,636,000 shares and 4,754,000 shares attributable
to outstanding stock options were excluded from the calculation of diluted
earnings per share because the exercise prices of the stock options were
greater than or equal to the average price of our common shares and
therefore their inclusion would have been anti-dilutive. For the six
months ended June 30, 2005 and 2004, respectively, 4,596,000 and 4,754,000
shares were excluded from the calculation of diluted earnings per share
because their effect would have been anti-dilutive.

The assumed increase in net income related to the after tax
compensation expense related to dividends on restricted shares was $314.8$224.0
thousand for each of the three month periods ended June 30, 2005 and 2004,
and $448.0 thousand and $274.8$424.0 thousand for the threesix months ended March 31,June 30,

6. Our wholly and partially owned agencies operate within the advertising,
marketing and corporate communications services industry. These agencies
are organized into agency networks, virtual client networks, regional
reporting units and operating groups. Consistent with the fundamentals of
our business strategy, our agencies serve similar clients, in similar
industries, and in many cases, the same clients across a variety of
geographies. In addition, our agency networks have similar economic
characteristics and similar long-term operating margins, as the main
economic components of each agency are the salary and service costs
associated with providing professional services, the office and general
costs associated with office space and occupancy, and the provision of
technology requirements which are generally limited to personal computers,
servers and off-the-shelf software. Therefore, given these similarities
and in accordance with the provisions of SFAS 131 - Disclosures about
Segments of an Enterprise and Related Information, most specifically
paragraph 17, we aggregate our operating segments, which are our agency
networks, into one reporting segment.

7. Bank loans at March 31,June 30, 2005 of $11.9$131.6 million are primarily comprised of
domestic borrowings and bank overdrafts of our international subsidiaries
which are treated as unsecured loans pursuant to our bank agreements. We
had unsecured committed revolving credit facilities of $2,000.0$2,500.0 million as
of March 31,June 30, 2005. There were no borrowings under the revolving credit
facilities and no commercial paper was outstanding as of March 31,June 30, 2005.

On May 23, 2005, we amended and extended our existing $1,500.0
million revolving credit facility with a consortium of banks, resulting in
a five-year $2,100.0 million revolving credit facility which matures May
23, 2010. On June 30, 2005, we entered into a new $400.0 million 364-day
revolving credit facility with a maturity date of June 29, 2006. This
facility replaced our previous $500.0 million 364-day revolving credit
facility that expired May 24, 2005. This facility includes a provision
that allows us to convert all amounts outstanding at expiration of the
facility into a one-year term loan.

In funding our day-to-day liquidity, we are an active participant in
the commercial paper market with a $1,500.0 million program. Our $2,100.0
million revolving credit facility provides credit support for commercial
paper issued under this program.

The consortium for the five-year facility consists of 27 banks.
Citibank N.A. acts as administrative agent, ABN Amro acts as syndication
agent and JPMorgan Chase Bank and HSBC Bank USA act as co-documentation
agents for the facility. Other significant lending institutions include
Societe Generale, Bank of America, Wachovia and Sumitomo Mitsui.

OMNICOM GROUP INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued)

The consortium for the 364-day facility consists of eight banks.
Citibank N.A. acts as administrative agent. ABN Amro acts as syndication
agent and JPMorgan Chase Bank, Bank of America, and Banco Bilbao Vizcaya
Argentaria act as co-documentation agents for the facility.

These revolving credit facilities provide us with the ability to
classify our borrowings that could come due within one year as long-term
debt, as it is our intention to keep the borrowings outstanding on a
long-term basis.

8. Included in operating income for the threesix months ended March 31,June 30, 2005 is a
pre-tax net gain of $6.9 million arising from the sale in the first
quarter of a majority owned business located in Australia and New Zealand
and the disposal of a non-strategic business located in the United States.
Due to an unusually high book tax rate caused by the non-deductibility of
goodwill, the book tax cost of the transactions was $6.1 million. After
deducting minority interest expense, the impact of these transactions
increased net income by $0.4 million.

9. In 2002, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 148 (SFAS 148),
"Accounting for Stock-Based Compensation - Transition and Disclosure - An
Amendment of FASB No. 123". We adopted Statement of Financial Accounting
Standards No. 123 (SFAS 123), "Accounting for Stock-Based Compensation"
effective January 1, 2004. Pre-tax stock-based employee compensation costs
for the threesix months ended March 31,June 30, 2005 and 2004, were $26.0$47.4 million and
$31.7$61.6 million, respectively.

In December 2004, the FASB issued SFAS No. 123R which is effective for annual
reporting periods beginning after JuneDecember 15, 2005 and generally applies
to grants made after adoption. SFAS 123R is a revision of SFAS 123.
Recently, the SEC Staff delayed the effective date of SFAS 123R to the
first quarter of 2006 for grants made after January 1, 2006. As a result
of our adoption ofBecause we previously adopted SFAS 123, as amended by SFAS 148, on January

amount of compensatory damages plus costs and attorneys' fees. Defendants
moved to dismiss the complaint and on March 28, 2005, the court dismissed
portions (1) and (3) of the complaint detailed above. The court's decision
denying the defendants' motion to dismiss the remainder of the complaint
did not address the ultimate merits of the case, but only the sufficiency
of the pleading. Defendants have answered the complaint, and discovery has
commenced.

In addition, on June 28, 2002, a derivative action was filed
purportedly on behalf of Omnicom in New York stateState court. On February 18,
2005, a second shareholder derivative action, again purportedly brought on
behalf of the Company, was filed in New York State court. The derivative

Executive Summary

We are a strategic holding company. We provide professional services to
clients through multiple agencies around the world. On a global, pan-regional
and local basis, our agencies provide these services in the following
disciplines: traditional media advertising, customer relationship management,
public relations and specialty communications. Our business model was built and
evolves around clients. While our companies operate under different names and
frame their ideas in different disciplines, we organize our services around
clients. The fundamental premise of our business is that our clients' specific
requirements should be the central focus in how we structure our business
offering and allocate our resources. This client-centric business model results
in multiple agencies collaborating in formal and informal virtual networks that
cut across internal organizational structures to deliver consistent brand
messages for a specific client and execute against our clients' specific
marketing requirements. We continually seek to grow our business with our
existing clients by maintaining our client-centric approach, as well as
expanding our existing business relationships into new markets and new clients.
In addition, we pursue selective acquisitions of complementary companies with
strong entrepreneurial management teams that typically either currently serve or
have the ability to serve our existing client base.

Globally, during the past few years, the overall industry has continued to
be affected by geopolitical unrest, lagging economic conditions, lack of
consumer confidence and cautious client spending. All of these factors
contributed to a difficult business environment and industry-wide margin
contraction. DuringThroughout this period, we have continued to invest in our
businesses and our personnel, and have taken actions to reduce costs at some of
our agencies to address the changing economic circumstances.

Several long-term trends continue to positively affect our business, including our
clients increasingly expanding the focus of their brand strategies from national
markets to pan-regional and global markets. Additionally, in an effort to gain
greater efficiency and effectiveness from their marketing dollars, clients are
increasingly requiring greater coordination of their traditional advertising and
marketing activities and concentrating these activities with a smaller number of
service providers. In recent periods, these trends, coupled with improving
economic conditions, have had a positive impact on our business.

Given our size and breadth, we manage the business by monitoring several
financial and non-financial performance indicators. The key financial
performance indicators that we review focus on the areas of revenues and
operating expenses.

Revenue growth is analyzed by reviewing the components and mix of the
growth, including: growth by major geographic location; growth by major
marketing discipline; growth from currency changes; growth from acquisition and
growth from our largest clients.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (Continued)

In recent years, our revenue has historically been divided almost evenly
between domestic and international operations. For the three months ended March
31,June
30, 2005, our overall revenue growth was 7.7%8.6% compared to the prior year period,
of which 2.1%2.2% was related to changes in foreign exchange rates and (0.2)(0.6)% was
related to entities acquired, net of disposals. The remaining 5.8%7.0% was organic
growth. For the six months ended June 30, 2005, our overall revenue growth was
8.2% compared to the prior year period, of which 2.2% was related to changes in
foreign exchange rates, (0.4)% was related to entities acquired, net of
disposals and the remaining 6.4% was organic growth.

We measure operating expenses in two distinct cost categories: salary and
service costs, and office and general expenses. Salary and service costs are
comprised primarily of employee compensation related costs. Office and general
expenses are comprised primarily of rent and occupancy costs, technology related
costs and depreciation and amortization.

Each of our agencies require service professionals with a skill set that
is common across our disciplines. At the core is their ability to understand a
client's brand and its selling proposition, and their ability to develop a
unique message to communicate the value of the brand to the client's target
audience. The office space requirements of our agencies are also similar across
geographies and disciplines, and their technology requirements are generally
limited to personal computers, servers and off-the-shelf software.

Because we are a service business, we monitor these costs on a percentage
of revenue basis. Salary and service costs tend to fluctuate in conjunction with
changes in revenues, whereas office and general expenses, which are not directly
related to servicing clients, tend to decrease as a percentage of revenue as
revenues increase because a significant portion of these expenses are relatively
fixed in nature. During the first three monthssecond quarter of 2005, salary and service costs
increased slightly to 72.0%68.9% of revenue from 71.4%68.7% of revenue in the first three monthssecond
quarter of 2004, due toas these costs increased staffing levels at certain of our companies, and due in part to our continuing efforts to restore incentive-based compensation.line with the increase in revenues.
Office and general expenses declined to 17.3%16.5% of revenue in the first three monthssecond quarter
of 2005 from 18.3%17.0% in the first three monthssecond quarter of 2004, as a result of our continuing
efforts to leverage fixed costs and better align these costs with business
levels on a location-by-location basis. Similarly, during the first six months
of 2005, salary and service costs increased marginally to 70.4% of revenue from
70.0% of revenue in the first six months of 2004, and office and general
expenses declined to 16.8% of revenue in the first six months of 2005 from 17.7%
in the first six months of 2004.

Our net income for the firstsecond quarter of 2005 increased by 11.0%9.6% to $150.5$225.8
million from $135.6$206.1 million in the firstsecond quarter of 2004, and our diluted EPS

The components and percentages are calculated as follows:

o The foreign exchange impact component shown in the table is
calculated by first converting the current period's local currency
revenue using the average exchange rates from the equivalent prior
period to arrive at a constant currency revenue (in this case
$2,355.3$2,561.9 million for the Total column in the table). The foreign
exchange impact equals the difference between the current period
revenue in U.S. dollars and the current period revenue in constant
currency (in this case $2,403.0$2,615.8 million less $2,355.3$2,561.9 million for
the Total column in the table).

o The acquisitions component shown in the table is calculated by
aggregating the applicable prior period revenue of the acquired
businesses. Netted against this number is the revenue of any
business included in the prior period reported revenue that was
disposed of subsequent to the prior period.

o The organic component shown in the table is calculated by
subtracting both the foreign exchange and acquisition revenue
components from total revenue growth.

o The percentage change shown in the table of each component is
calculated by dividing the individual component amount by the prior
period revenue base of that component (in this case $2,231.4$2,407.8 million
for the Total column in the table).

As indicated, foreign exchange impacts increased our international revenue
by $47.7$53.9 million during the quarter ended March 31,June 30, 2005. The most significant
impacts resulted from the continued period-over-period strengtheningstrength of the Euro and the British Pound against the
U.S. dollar, as our operations in these markets represented approximately 70% of
our international revenue.

increase resulted from $8.0 million of additional interest costs associated with
the amortization of payments we made to consenting holders of certain of our

Salary and service costs, which are comprised of direct service costs and
salary and related costs, increased by $286.9 million, or 8.8%, and represented
80.7% of total operating expenses in the first six months of 2005 versus 79.9%
in the first six months of 2004. Most, or $286.9 million and 91.5%, of the
$313.4 million total increase in operating expenses in the first six months of
2005 resulted from increases in salary and service costs. This increase was
primarily attributable to increased revenue levels and the required increases in
direct salary and salary related costs necessary to deliver our services and
pursue new business initiatives, including our continuing efforts to restore
incentive-based compensation pools commensurate with our performance and
increases in freelance labor costs. As a result, salary and service costs as a
percentage of revenues increased marginally from 70.0% in the first six months
of 2004 to 70.4% in the first six months of 2005.

Office and general expenses, which are comprised of office and equipment
rent, technology costs and depreciation and amortization of identifiable
intangibles, professional fees and other overhead expenses, increased by $26.5
million, or 3.2%, in the first six months of 2005 compared to the same period in
2004. Office and general expenses decreased as a percentage of our total
operating costs in the first six months of 2005 to 19.3% versus 20.1% in the
prior period. Additionally, as a percentage of revenue, office and general
expenses decreased in the first quartersix months of 2005 to 17.3%16.8% from 18.3%17.7% in the
first quartersix months of 2004, because theseas a result of our higher utilization of our fixed
cost base stemming in part from leveraging our real estate commitments and other
occupancy and office related costs over a higher revenue base. These expenses
are relatively fixed in nature and do not necessarily change relative to our
revenue growth or changes in our salary and
services costs.growth. Included in office and general expenses in the first quarter of
2005 was a pre-tax $6.9 million net gain related to the sale of a majority owned
business located in Australia and New Zealand and the disposal of a
non-strategic business located in the United States. Additionally, included in
office and general expenses in the first quarter of 2004 was a $3.2 million
pre-tax net gain arising from Seneca Investment LLC's recapitalization, offset
by losses from the disposal of other cost-based investments and costs incurred
in connection with the disposal of two non-strategic businesses.

The impact of these transactions
on our operating income, margins, income taxes and net income is summarized
below:

The table above is intended to facilitate the above discussion regarding
the results of our operations. As a result of the adjustments above, the
"Adjusted" numbers are non-GAAP measures. We believe that by making the
adjustments above, the "Adjusted" numbers are more comparable to previous
quarters and thus more meaningful for the purpose of this analysis. The impact
on revenue of these dispositions is included in our discussion of changes in the
Revenue section on page 10 and the impact on operating results was not
significant.

Net Interest Expense: Our net interest expense in the first quartersix months of
2005 was $12.1$26.4 million, up from $10.4$17.7 million in the same period in 2004. The
increase resulted from $3.6$13.1 million of additional interest costs associated
with the amortization of payments we made to consenting holders of certain of
our convertible notes during the second half of 2004, as an incentive to the
noteholders to consent to certain amendments to our indentures and not to
exercise certain put rights. In August 2004, we paid $24.5 million in the
aggregate to consenting holders of our Zero Coupon Zero Yield Convertible Notes
due 2032 and in November 2004, we paid $14.8 million and $1.2 million in the
aggregate to consenting holders of our Liquid Yield Option Notes due 2031 and
Zero Coupon Zero Yield Convertible Notes due 2033, respectively. Furthermore,
interest expense relative to our (euro)152.4 million 5.20% Euro notes increased
due to the foreign currency change of the Euro relative to the U.S. dollar. This
increase was partially offset by lower short-term interest rates and cash management efforts during the quarter.first-half
of 2005.

Critical Accounting Policies

To assist in better understanding our financial statements and the related
management's discussion and analysis of those results, readers are encouraged to
consider this information together with our discussion of our critical
accounting policies under the heading "Management's Discussion and Analysis of
Financial Condition and Results of Operations" in our Annual Report on Form 10-K
for the year ended December 31, 2004 (the "2004 Form 10-K"), as well as our
consolidated financial statements and the related notes included in our 2004
Form 10-K, for a more complete understanding of all of our accounting policies.

New Accounting Pronouncements

In December 2004 the FASB issued SFAS No. 123R which has becomeis effective for annual
reporting periods beginning after JuneDecember 15, 2005 and generally applies to
grants made after adoption. SFAS 123R is a revision of SFAS 123. Recently, the
SEC staff delayed the effective date of SFAS 123R to the first quarter of 2006
for grants made after January 1, 2006. As a result of our adoption ofBecause we
previously adopted SFAS 123, as amended by SFAS 148, on January 1, 2004, we
believe that the adoption of SFAS 123R will not have a material impact on our
consolidated results of operations or financial position. However, we are in the
process of assessing the full impact and related disclosure requirements of this
revision.

The FASB issued two staff proposals on accounting for income taxes to
address recent changes enacted by the United States Congress. Proposed Staff
Position FAS 109-a, Application of FASB Statement No. 109, Accounting for Income
Taxes, for the Tax Deduction Provided to U.S. Based Manufacturers by the
American Jobs Creation Act of 2004, and Proposed Staff Position FAS 109-b,
Accounting and Disclosure Guidance for the Foreign Earnings Repatriation
Provisions within the American Jobs Creation Act of 2004. We believe that
Proposed Staff Position FAS 109-a does not apply to our business and we are
currently assessing the impact of Proposed Staff Position FAS 109-b; however, we
do not believe it will have a material impact on our consolidated results of
operations or financial position.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (Continued)

Contingent Acquisition Obligations

Certain of our acquisitions are structured with contingent purchase price
obligations, often referred to as earn-outs. We utilize contingent purchase
price structures in an effort to minimize the risk to us associated with
potential future negative changes in the performance of the acquired entity
during the post-acquisition transition period. These payments are not contingent
upon future employment. The aggregate amount of future contingent purchase price
payments that we would be required to pay for prior acquisitions, assuming that
the businesses perform over the relevant future periods at their current profit
levels, is approximately $428$372 million as of March 31,June 30, 2005. The ultimate amounts
payable cannot be predicted with reasonable certainty because it is dependent
upon future results of operations of subject businesses and is subject to
changes in foreign currency exchange rates. In accordance with GAAP, we have not
recorded a liability for these items on our balance sheet since the definitive
amount is not determinable or distributable. Actual results can differ from
these estimates and the actual amounts that we pay are likely to be different
from these estimates. Our obligations change from period to period primarily as
a result of payments made during the current period, changes in the acquired
entities' performance and changes in foreign currency exchange rates. These
differences could be significant. The contingent purchase price obligations as
of March 31,June 30, 2005, calculated assuming that the acquired businesses perform over
the relevant future periods at their current profit levels, are as follows:

In addition, owners of interests in certain of our subsidiaries or
affiliates have the right in certain circumstances to require us to purchase
additional ownership stakes in those companies. Assuming that the subsidiaries
and affiliates perform over the relevant periods at their current profit levels,
the aggregate amount we could be required to pay in future periods is
approximately $250$246 million, $137$139 million of which relate to obligations that are
currently exercisable. If these rights are exercised, there would be an increase
in our net income as a result of our increased ownership and the reduction of
minority interest expense. The ultimate amount payable relating to these
transactions will vary because it is primarily dependent on the future results
of operations of the subject businesses, the timing of the exercise of these
rights and changes in foreign currency exchange rates. The actual amount that we
pay is likely to be different from this estimate and the difference could be
significant. The obligations that exist for these agreements as of March 31,June 30,
2005, calculated using the assumptions above, are as follows:

Liquidity and Capital Resources

Our principal non-discretionary funding requirement is our working
capital
requirement.capital. In addition, we have contractual obligations related to our debt and
convertible notes, our recurring business operations primarily related to lease
obligations, as well as certain contingent acquisition obligations related to
acquisitions made in prior years. Historically, substantially all of our
non-discretionary cash requirements have been funded from operating cash flow.

Our principal discretionary cash requirements include dividend payments to
our shareholders, repurchases of our stock, payments for strategic acquisitions
and capital expenditures. The repurchases of our stock during the second quarter
of 2005 are summarized in Part II, Item 2 "Unregistered Sales of Equity
Securities and Use of Proceeds" of this Report on Form 10-Q.

We have a seasonal working capital cycle. Working capital requirements are
lowest at year-end and higher during the first, second and third quarters. This
cycle occurs because in the majority of our businesses we act as agent on behalf
of our clients, including when we place media and incur production costs on
their behalf. We generally require collection from our clients prior to our
payment for the media and production cost obligations and these obligations are
greatest at the end of the year.

Historically, on an annual basis, our discretionary and non-discretionary
spending has been funded from operating cash flow. However, during the year we
manage liquidity by utilizing our credit facilities discussed below.

Liquidity: We had cash and cash equivalents totaling $588.1$343.5 million and
$1,165.6 million at March 31,June 30, 2005 and December 31, 2004, respectively. We also
had short-term investments totaling $17.3$21.6 million and $574.0 million at March
31,June 30,
2005 and December 31, 2004, respectively. Consistent with our historical trends
in the first threesix months of the year, we had negative cash flow from operations
of $717.0$570.2 million. We funded this deficit primarily with cash on hand,
liquidation of short-term investments and by managing our working capital.

Capital Resources: On May 24, 2004,23, 2005, we amended and extended our existing
revolving credit facilities with a consortium of banks, resulting in a five-year
$1,500.0$2,100.0 million revolving credit facility which matures May 24, 2009, and23, 2010. On June
30, 2005, we entered into a $500.0new $400.0 million 364-day revolving credit facility
with a maturity date of May 23,
2005, which we expect to amend and extend in the near future. These facilitiesJune 29, 2006. The five-year facility amended our
previous three-year, $835.0 million and $1,200.0 million, 364-day

The consortium for the 364-day facility consists of eight banks. Citibank
N.A. acts as administrative agent, ABN Amro acts as syndication agent and
JPMorgan Chase Bank, Bank of America, and Banco Bilbao Vizcaya Argentaria act as
co-documentation agents for the facility.

These facilities are a critical component in our analysis of the liquidity
and capital resources that provide us with the ability to classify up to
$2.0 billion$2,500.0 million of our borrowings that could come due within one year as
long-term debt, when it is our intention to keep the borrowings outstanding on a
long-term basis.

Debt: We had short-term bank loans of $11.9$131.6 million and $17.5 million at
March 31,June 30, 2005 and December 31, 2004, respectively, which are comprised of
domestic borrowings and bank overdrafts of our international subsidiaries and
are treated as unsecured loans pursuant to our bank agreements.

At March 31,June 30, 2005, we also had a total of $2,339.3 million aggregate
principal amount of convertible notes outstanding, including $847.0 million
Liquid Yield Option Notes due 2031, which were issued in February 2001, $892.3
million Zero Coupon Zero Yield Convertible Notes due 2032, which were issued in
March 2002, and $600.0 million Zero Coupon Zero Yield Convertible Notes due

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

Our results of operations are subject to risk from the translation to the
U.S. dollar of the revenue and expenses of our foreign operations, which are
generally denominated in the local currency. For the most part, our revenues and
the expenses incurred related to those revenues are denominated in the same
currency. This minimizes the impact that fluctuations in exchange rates have on
our profit margins.

Our Annual Report on Form 10-K for the year ended December 31, 2004
provides a more detailed discussion of the market risks affecting our
operations. As of March 31,June 30, 2005, no material change had occurred in our market
risks from the disclosure contained in that 10-K.

Forward-Looking Statements

"Management's Discussion and Analysis of Financial Condition and Results
of Operations" and "Quantitative and Qualitative Disclosures About Market Risk"
and other information set forth in, or incorporated by reference into or
referenced in, this report contain disclosures which are forward-looking
statements within the meaning of the federal securities laws. Forward-looking
statements include all statements that do not relate solely to historical or
current facts, and can be identified by the use of words such as "may," "will,"
"expect," "project," "estimate," "anticipate," "envisage," "plan" or "continue."
These forward-looking statements are based upon our current plans or
expectations and are subject to a number of uncertainties and risks that could
significantly affect current plans and anticipated actions and our future
financial condition and results. The uncertainties and risks include, but are
not limited to, changes in general economic conditions, competitive factors,
client communication requirements, the hiring and retention of human resources
and other factors. In addition, our international operations are subject to the
risk of currency fluctuations, exchange controls and similar risks discussed
above. As a consequence, current plans, anticipated actions and future financial
condition and results may differ from those expressed in any forward-looking
statements made by us or on our behalf, and those differences could be material.

ITEM 4. CONTROLS AND PROCEDURES

We have established and maintain disclosure controls and procedures and
internal controls over financial reporting designed to ensure that information
required to be disclosed in our SEC reports is recorded, processed, summarized
and reported within applicable time periods. We conducted an evaluation, under
the supervision and with the participation of our management, including our CEO
and CFO, of the effectiveness of our disclosure controls and procedures as of
March 31,June 30, 2005. There have not been any changes in our internal controls over
financial reporting that occurred during our first fiscal quarter that has
materially affected or is reasonably likely to materially affect our internal
controls over financial reporting. Based on that evaluation, our CEO and CFO concluded that as of
March 31,June 30, 2005, our disclosure controls and procedures are effective to ensure
recording, processing, summarization and reporting of information required to be
included in our Quarterly Report on Form 10-Q for the quarter ended March 31,June 30,
2005 as appropriate to allow timely decisions regarding required disclosure.
There have not been any changes in our internal controls over financial
reporting that occurred during our first and second fiscal quarter that has
materially affected or is reasonably likely to materially affect our internal
controls over financial reporting. Our independent registered public accounting
firm, KPMG LLP, has audited our financial statements for the year ended December
31, 2004 and issued an attestation report, dated March 11, 2005, on our
assessment of our internal control over financial reporting.
