BETHESDA, Md.--(BUSINESS WIRE)--April 10, 2000

e-MEDx Inc., a leader in Web-based care management software solutions, today announced that it has signed a joint agreement with XCare.net (Nasdaq:XCAR), a leading eBusiness solutions and service provider for healthcare organizations.

Through this agreement, XCare.net can begin integrating three e-MEDx products into eHealth solutions for its business clients -- e-PHA, e-POC and MedAdvice(R) 2001. These products will enhance XCare.net's ability to effectively deliver end-to-end Web-based solutions to healthcare organizations. Likewise, e-MEDX will begin selling XCare.net products as an extension of e-MEDx's current product offering.

"This agreement expands our existing product suite and increases our distribution channels by partnering with the leader in XML-based managed care applications," said John Dwyer, CEO of e-MEDx. "By using e-MEDx products, XCare.net will be able to help its business clients streamline the preventive healthcare process and provide additional technology solutions so their clients can deliver a higher level of care to patients."

XCare.net will deploy the following products:

-- e-PHA (Predictive Health Assessment)--Enables care management

organizations and employers to assess quickly and efficiently

the health of their member or employee population and

identify those individuals with the highest potential for

having high cost health conditions.

-- e-POC (Plan Of Care)--Allows medical management organizations

to quickly identify the most appropriate plan of care for

patients with chronic diseases and create a care plan based

on an online library of guidelines and care plans.

-- MedAdvice(R) 2001--Automates a case manager's workflow 

through an integrated system of checks and balances,

providing the information needed by a reviewer to effectively

handle any type of authorization at any level of service.

"Both XCare.net and e-MEDx are technology enablers and use XML," said Tom Pianko, XCare.net's senior vice president of sales and business development. "Both companies have core `engine' products, but e-MEDx primarily focuses on clinical transactions, while XCare.net primarily focuses on developing end-to-end, web-based solutions, including back-office managed care business and administrative transactions. There is minimal overlap in our product lines and tremendous synergy in our business models."

By partnering to distribute complementary products, both e-MEDx and XCare.net will improve the ability to deliver complete Web-based solutions to their target healthcare markets.
