ZymeTx, Inc. (OTCBB:ZMTX):

Agreement Expands ZstatFlu Availability into New Market Segment

And Utilizes MedCenterDirect Electronic Distribution System

The nation's largest trade association serving America's poor and medically underserved, the National Association of Community Health Centers (NACHC), with ZymeTx (OTCBB: ZMTX) will offer the Company's ZstatFlu(R) influenza diagnostic test to the 3,200 health center sites across the United States.

"This relationship establishes a product presence for ZstatFlu within a medically vulnerable segment of America's population, where unchecked flu can spur serious unintended health and financial consequences," observed Norman Proulx, President and Chief Executive Officer of ZymeTx, Inc. "Our alignment with the NACHC advances ZymeTx's strategic initiative to support organizations charged with health care responsibilities for significant population bases. This arrangement creates the potential for repetitive long-term, multi-unit sales opportunities for ZstatFlu," Proulx said.

Community Health Centers service 11 million people at delivery sites in all 50 states, the District of Columbia, Puerto Rico, Guam and the U.S. Virgin Islands. Community Health Centers strive to address access problems in areas with few or no physicians and other health and social services.

The partnership complements the broad initiative on behalf of the NACHC and Community Health Centers to establish an influenza disease management program at the grassroots level.

"The utilization of a rapid influenza diagnostic test is the first line of defense to prevent the spread of flu among this susceptible segment of our population," stated Dr. Tom Curtin, NACHC Chief Medical Officer. "The use of this test can lower health care costs while at the same time improve the overall quality of care."

"The agreement with ZymeTx for ZstatFlu is consistent with the NACHC's mission to promote and deliver quality health care to the medically underserved populations. ZstatFlu offers a proven method to detect flu so it can be properly and promptly treated," Curtin commented.

ZstatFlu is the first FDA-approved rapid flu diagnostic test to detect both Influenza A and B from a throat swab specimen with 99-percent specificity on positive tests, based on actual clinical trials. The test, which produces results in 20 minutes, will serve as the centerpiece of a new NACHC Influenza Starter Kit. Community Health Centers will receive kits for the 2001/2002 winter flu season.

The agreement designates MedCenterDirect as the exclusive electronic distributor of ZstatFlu to Community Health Centers, which will order ZstatFlu tests through the MedCenterDirect web site at www.medcenterdirect.com.

"MedCenterDirect will play a very important role in the success of this initiative by providing a highly efficient ordering process to ensure the timely delivery of products to Community Health Centers," stated Proulx.

MedCenterDirect links clinicians and suppliers through Internet e-commerce technology. "MedCenterDirect streamlines administrative and financial functions for providers," said Dr. Curtin. "Its cost-savings system will allow Community Health Centers to more effectively manage their medical inventories."
