IRIS Enters Exclusive Supply Agreement with Premier, Inc., A Group Purchasing Organization Representing 1,500 Hospitals

Provides Broad Sales and Marketing Exposure for New iQ200 System


CHATSWORTH, Calif., April 1, 2004 (PRIMEZONE) -- IRIS International, Inc. (AMEX:IRI), a manufacturer and marketer of automated IVD urinalysis systems and medical devices used in hospitals and reference clinical laboratories worldwide, today announced that it has entered into an exclusive supply agreement for its new iQ(r)200 Automated Urine Microscopy Analyzer with the Premier Purchasing Partners LP unit of Premier, Inc., a leading healthcare alliance that provides more than $17 billion in medical supplies and equipment annually to 1,500 participating hospitals and other healthcare facilities.

Premier has chosen Iris Diagnostics' iQ200 Automated Microscopy Analyzer to be its sole source product for urine microscopy, and IRIS is the only company with a Premier contract for a system combining both urine chemistry and microscopy. IRIS will share the Premier award for urine chemistry analyzers with one other company.

Iris Diagnostics will be able to sell to Premier participating members its new line of urinalysis products, including its flagship iQ200 System, the stand-alone iQ200 Automated Microscopy Analyzer, and the urine chemistry analyzers distributed by IRIS, the AUTION MAX(tm) AX-4280 and AUTION JET(tm) AJ-4270. The AX-4280 and AJ-4270 are manufactured by Arkray, Inc., Kyoto, Japan, IRIS's business partner. The combination of IRIS's iQ200 Automated Urine Microscopy Analyzer and the AUTION MAX AX-4280 Automated Urine Chemistry Analyzer, linked through proprietary hardware and software, becomes the iQ200 System.

"This is the first agreement IRIS has signed with a large group purchasing organization and provides IRIS an excellent opportunity to increase market penetration with the iQ200 and our extended line of urinalysis products and consumables," stated President and Chief Executive Officer Cesar Garcia. "Premier's broad reach into hundreds of medical institutions and healthcare facilities opens the way for accelerated sales of the iQ200 System," Mr. Garcia said. "We are particularly satisfied with the selection by Premier of the iQ200 Automated Microscopy Analyzer as the exclusive product for urine microscopy applications. The iQ200 already has established a reputation as a cutting-edge medical diagnostic tool since its launch in August 2003."

"After a comprehensive review of bids in each product category, Premier awards contracts that we believe represent the best overall value to its membership," stated David Gooden, Product Manager - Hematology, Coagulation and Urine, Premier Purchasing Partners LP. "Iris has received two such contract awards. IRIS's ability to provide a comprehensive solution for both urine chemistry and microscopy to our members was a major contributing factor to awarding the contract. We look forward to our partnership with Iris, which commences April 1, 2004."

Premier has a field force of 51 Regional Directors and 13 Regional Vice Presidents who promote contract uptake and compliance among their members. Iris Diagnostics's domestic sales force will sell the Company's instruments and consumables directly to Premier participating members with marketing support from Premier.

"Premier has the capability of extending IRIS's marketing efforts with tremendous group purchasing power that reaches into the buyers and purchasing managers of hundreds of major hospitals and institutions," Mr. Garcia noted. "We estimate that Premier represents some 500 laboratories performing more than 45 urine microscopies per day; our immediate target market for the iQ200 System."

The initial key target market for the iQ200 Automated Microscopy Analyzer is an estimated 2,500 laboratories in the U.S. and 6,000 internationally; those laboratories performing more than 45 urine microscopy tests per day.
