two strategic acquisitions - one closed, one pending - are decisive
moves toward executing our corporate growth strategy. While we worked
toward these important deals, we also continued to demonstrate our
ability to drive organic growth by delivering both a solid quarter and
an important new product release - eHealth(R) Suite 5.7. In addition,
I am pleased by the speed with which our new Executive Vice President
of Worldwide Field Operations, Ted Williams, has assumed leadership of
our sales and service organizations."

    Fourth Quarter Results

    Acquisitions - Closed and Pending - to Expand Product Offering

    --  Aprisma Management Technologies - Concord's vision of managing
        IT services end-to-end, including networks, systems, and
        applications will be broadened with the addition of SPECTRUM's
        functionality. Post acquisition, Concord's capabilities will
        include patented event correlation, root cause analysis,
        technology relationship mapping, topology discovery and
        display, and service modeling.

    --  Vitel Software - With the acquisition of Vitel Software,
        Concord becomes the only software company to proactively
        manage the performance of voice networks that are based on
        next-generation voice over IP, legacy TDM technology, or both.

    Number of Large eHealth(R) Suite Deals Increases, Revenue Grows

    --  The number of eHealth(R) Suite deals over $100,000 increased
        to 46, from 40 in the previous quarter.

        accounts was $124,000. New customers include Walgreens, the

        revenue grew 14% sequentially from Q3.

        customer interest, including organizations such as
        Northwestern Medical Faculty Foundation in Chicago, CheckFree
        Corporation in Georgia, Bayer Business Services in Germany,
        and SPT, a service provider in Australia.

    --  Voice - Vitel attracted new business for its voice network
        performance management solution from organizations like the

        Kline, purchase more modules to expand management of its
        hybrid voice network and voice mail system.

    --  Mobile Wireless - Concord continued to see customer traction
        from major mobile wireless carriers such as Verizon Wireless

    Forward-looking statements made in this press release, including
forward-looking statements regarding revenue and profit and loss
expectations, market information and statements regarding our
acquisitions and the expected benefits therefrom, are made pursuant to
the safe harbor provisions Section 21E of the Securities Exchange Act
of 1934. Readers are cautioned that all forward-looking statements
involve risks and uncertainties, and actual results could differ
materially from the forward-looking statements contained herein. Risks
and uncertainties include, without limitation, continuation of the
slower than expected economic recovery in certain of our markets; the
failure to consummate the Aprisma acquisition; our customers' ability
to obtain funding, specifically in light of the aforementioned
economic climate, and the resulting potential delay or cancellation of
pending customer purchases; risks of operating losses including the
cost of development and sale of our products; the integration of
acquired products and technologies; the ability to attract and retain
key employees; issues that impact the use of our intellectual
property; risks associated with our debt service obligations; market
acceptance of, and demand for, our products; risks associated with
competition, including competition in the business service management
market and the network, system, and application fault and performance
markets; risks associated with international sales, including foreign
currency risks and longer payment cycles; and other risks detailed in
the Company's filings with the Securities and Exchange Commission,
including but not limited to, the Company's annual report on Form 10-K
and quarterly reports on Form 10-Q. Any forward-looking statements
should be considered in light of all these factors. The information
contained in this press release is applicable only today and should
thereafter be considered historical and will no longer constitute the
Company's current expectations. The Company undertakes no obligation
to update information contained in this press release.

    Pro Forma Financial Results

    We prepare and release quarterly unaudited financial statements
prepared in accordance with generally accepted accounting principles
("GAAP"). We also disclose and discuss certain pro forma financial
information, used to evaluate our performance, in this and other
earnings releases and investor conference calls. We believe that
current shareholders and potential investors in our company use
multiples of pro forma EPS in making investment decisions about our
company. We use pro forma EPS to evaluate the results of our ongoing
operations and to assist in historical comparisons. This measure, and
other pro forma information, should not be considered an alternative
to measurements required by accounting principles generally accepted
in the United States of America such as net income and net cash
provided by operations and should not be considered measures of our
liquidity. In addition, our non-GAAP measures may not be comparable to
similar measures reported by other companies. Our key non-GAAP measure
is: pro forma EPS and is calculated by dividing pro forma net income
by the diluted number of shares.

    Pro forma net income excludes certain non-cash and special
charges, considered non-recurring, which consist primarily of non-cash
and cash compensation expenses, in-process-research-and-development
costs, acquisition related costs and amortization of intangible
assets. In the quarter ending March 31, 2005, pro forma net income
also excludes acquisition related expenses related to the acquisitions
of Vitel (closed) and Aprisma (pending); and acquisition-related
compensation charges stemming from Aprisma.

    This pro forma calculation also substitutes current period GAAP
tax provisions with a pro forma tax rate of 28%.

    From a tax return perspective, and thus cash flow perspective, we
do not believe Concord will pay significant state or federal income
taxes for at least 2 years. We will continue incurring small foreign,
federal minimum and state minimum tax payments. We will continue
providing pro forma guidance and results at a 28% tax rate to
normalize our results against historical reported results, and such
pro forma guidance and results are provided for comparative purposes
only.
