    Customer Highlights

    Citrix closed several large customer agreements during the
quarter, including France Telecom, London Borough of Haringey, and US
Air Force Personnel Command.
    France Telecom, one of the world's leading telecommunications
carriers with 118.6 million customers on five continents, continued
its rollout of Citrix access infrastructure with the implementation of
more than 14,000 additional seats of Citrix(R) MetaFrame(R)
Presentation Server. This expansion of the Citrix deployment enables
secure, easy and instant access to business-critical applications,
including SAP, Vantive and many applications geared specifically to
the telecommunications industry, regardless of location or network
connection.
    Haringey, one of London's 32 boroughs, has licensed 3,800 Citrix
MetaFrame Presentation Server seats. With Citrix access
infrastructure, Haringey will provide managed access to shared
resources, allowing borough employees to securely access more than
70 Microsoft(R) and proprietary applications used daily in the
ongoing management and development of the borough.
    US Air Force Personnel Command has implemented 5,000 licenses of
Citrix MetaFrame Presentation Server and MetaFrame Password Manager to
facilitate centralized and cost-effective application deployment and
ensure the security of its network. With Citrix access infrastructure,
the US Air Force Personnel Command benefits from secure, easy and
instant access to its Oracle human resources applications.

    Citrix Online

    Since its acquisition on March 1, 2004, the Citrix Online business
has performed on plan and has generated excitement from Citrix's
customer base. Beginning this quarter, Citrix will take the next step
in its plan to integrate Citrix Online and further leverage the Citrix
brand, channel partners and installed base for its new service-based
products.
    In conjunction with the next phase of the integration process,
Andreas von Blottnitz, who has successfully led Citrix Online for the
past five years, will be leaving Citrix in the fourth quarter. von
Blottnitz sees this new phase of integration as the best time for a
smooth transition. Brett Caine, senior vice president of sales for
Citrix Online, will assume the responsibilities of president beginning
August 1, 2004. von Blottnitz will continue to consult with the
company to ensure a smooth transition through October 1, 2004.
    Caine has successfully run sales for Citrix Online for the past
year, helping the business reach its sales goals and providing
additional operational discipline. Caine will report to John Burris,
senior vice president of worldwide sales and services for Citrix.
    "Brett has delivered outstanding results since joining the
division," said Klaus Schauser, founder and chief technology officer
for Citrix Online. "Brett has the full support of the management team
in Santa Barbara as well as the executive team at Citrix to lead the
division and drive a smooth hand-off. We look forward to much closer
sales and marketing coordination to gain partner and customer synergy
and leverage."

    Product Highlights

    During the second quarter, Citrix introduced MetaFrame Access
Suite 3.0, delivering to customers a complete and integrated access
infrastructure solution. This new version of the MetaFrame Access
Suite delivers security, mobility, flexibility, productivity and
performance, including the comprehensive management of MetaFrame
Presentation Server, the mobility and flexibility benefits of
MetaFrame Secure Access Manager, the single sign-on (SSO) and password
security offered by MetaFrame Password Manager, and the collaborative
resources of MetaFrame Conferencing Manager. One of the most important
advances of the Citrix MetaFrame Access Suite 3.0 is SmoothRoaming, a
new capability that ensures consistent mobile access that is always
on, and allows computing environments to follow users across
locations, devices and access outages.
    In other product news of the quarter, the popular products of the
Citrix Online Division continued to draw industry accolades. In April,
Citrix GoToMyPC(R) Corporate was chosen as a finalist in eWeek's
Excellence Awards program in the Personal Productivity category. The
finalists were selected from hundreds of high-quality entries by teams
composed of eWeek Labs analysts, eWeek Corporate Partners, and senior
IT professionals who represent eWeek's readers. Citrix GoToMyPC also
received PC World's 2004 World Class Award for best remote-access
software for the second consecutive year, clearly establishing itself
as the market leader in the Web-based remote access software category
for its fast, easy and secure access to desktop PCs. Additionally,
Citrix GoToAssist(TM) earned top distinctions from Customer
Interaction Solutions magazine, which awarded GoToAssist the 2004 CRM
Excellence Award, and CRM Advocate, which named GoToAssist the winner
in The Sixth Annual Users Choice Awards in the service and support

    Reconciliation of Non-GAAP Financial Measures to Comparable U.S.
GAAP Measures

    (Unaudited)

    We utilize certain non-GAAP financial measures to evaluate our
performance. We consider these measures important indicators of our
success. In addition, Citrix provides these non-GAAP measures of the
company's performance to investors to enable them to, among other
things, better compare Citrix's most recent results of operations
against financial models prepared by the company's investors and
securities analysts, and to provide additional information concerning
the impact of business acquisitions on Citrix's results of operations.
These measures should not be considered an alternative to measurements
required by accounting principles generally accepted in the
United States ("U.S. GAAP") such as net income and earnings per share
and should not be considered measures of our liquidity. In addition,
our non-GAAP financial measures may not be comparable to similar
measures reported by other companies.
    The following tables reconcile non-GAAP financial measures used in
this release to the most comparable U.S. GAAP measure for the
respective periods (in thousands, except for per share information and
percentages):
