    BOCA RATON, Fla.--(BUSINESS WIRE)--April 21, 2003--Eclipsys
Corporation(R) (Nasdaq:ECLP), The Outcomes Company(R), today released
results for the first quarter ended March 31, 2003.

    First quarter results

    First quarter 2003 revenues were $56.8 million compared to
revenues of $62.8 million in Q1'02 and revenues of $53.4 million in
Q4'02. Net loss for the quarter was $(13.0) million, compared to net
income of $5.3 million in the same period a year ago and a net loss of
$(14.9) million in Q4'02. Basic earnings (loss) per share was $(0.29),
compared to $0.12 in Q1'02 and $(0.33) in Q4 '02. This represents a
sequential improvement of $0.04 over the preceding quarter.
    Operating cash flows were $1.2 million, compared to $10.5 million
in Q1'02 and $7.0 million in Q4'02. Cash and marketable securities
were $180.0 million as of March 31, 2003, up from $174.5 million as of
March 31, 2002 and down sequentially from $183.5 million as of
Dec. 31, 2002. Days sales outstanding were 71 as of March 31, 2003, a
decrease of 26 days from the previous year and a decrease of eight
days from the preceding quarter. Deferred revenue was $85.0 million as
of March 31, 2003 compared to $59.3 million as of March 31, 2002.
Deferred revenues sequentially increased $5.8 million from
$79.2 million as of Dec. 31, 2002.
    "We are pleased with the progress we have made over the past
several quarters," said Robert J. Colletti, senior vice president and
chief financial officer. "Our first quarter results are consistent
with our expectations and reflect our continued investment in research
and development, as well as the expansion of our sales and marketing
organizations. Additionally, we continue to make improvements in our
operations as evidenced by our improvement in days sales outstanding
which decreased sequentially by eight days. This quarter represents
our tenth consecutive quarter of positive operating cash flows."

    SunriseXA marketplace acceptance

    "SunriseXA, our Web services-based advanced health information
management solution, is increasingly being selected by healthcare
organizations looking for information technology to address patient
safety, quality of care and workflow issues," said Paul L. Ruflin,
Eclipsys president and CEO. "The changes we have made to our business
model, the investments we are making in sales and marketing, and our
decision to expedite SunriseXA development for additional advanced
clinical functionality, are all having the desired impact to create
demand for Eclipsys solutions. Because of the marketplace acceptance
of SunriseXA, we are very excited about the future of Eclipsys."
    "Additionally, we continue to be recognized by independent third
parties who evaluate healthcare information technology organizations,"
added Ruflin. "The momentum we are experiencing in the marketplace
with our Sunrise solutions has recently been reflected by Frost &
Sullivan, a leading consulting firm, who ranked Eclipsys as having the
largest market share of full computerized physician order entry (CPOE)
solutions in the US urban hospital market. The study evaluated CPOE
solutions from various vendors currently in use at urban hospitals
nationwide. The study stated that Eclipsys has probably been the
fastest CPOE provider 'out of the gate.'"
    This latest accomplishment is in addition to the top industry
rankings that Eclipsys achieved during 2002 from independent research
groups such as KLAS and Five Rights Consulting, Inc., and in The
Medical Records Institute's Towards an Electronic Patient Record
(TEPR) Awards. Frost & Sullivan predicts a major increase in CPOE
utilization by 2005, as healthcare organizations increasingly look to
CPOE solutions to address patient safety and cost-saving
opportunities.
    "We are well positioned to capitalize on the market's keen
interest in advanced core clinical solutions," stated Ruflin. "Based
on the number of sites going live in 2003 combined with the growing
market acceptance of Eclipsys' advanced core clinical solution, we
expect to maintain and expand our lead in the marketplace going
forward."
