(NASDAQ:GIVN), today announced fourth quarter and year end results for the period ended December 31, 2001. The Company announced sales of $3.5 million for the fourth quarter of 2001 and $4.7 million for the full year. The fourth quarter was the first full quarter of sales for the Company for both the U.S. and European market following FDA clearance of the Given(R) Diagnostic Imaging system in August 2001. Sales reflect strong fourth quarter demand for the Given System from physicians, as well as an increase in capsule sales. On a geographic basis, sales of the Given System in the United States accounted for just under half of total annual revenues. A geographic breakdown of annual sales is as follows: <Table> <Caption> (MILLIONS OF US DOLLARS) United States $2.2 Europe $2.0 ROW $0.5 </Table> FOURTH QUARTER AND FULL YEAR 2001 FINANCIALS Revenues totaled $3.5 million during the fourth quarter.

FOURTH QUARTER HIGHLIGHTS During the Fourth quarter, Given Imaging accomplished the following milestones: - More than 3,600 M2A capsules were sold in 2001, of which approximately 2,000 represent reorders. - The Given System installed base reached 225, with 95 systems installed in the United States. Of this number, 166 systems were sold commercially and 59 were provided to physicians to support our sponsored clinical trials. - The Company entered into a group purchasing agreement with Premier, one of the largest purchasing organizations in the United States, for marketing the Given System to Premier's network of more than 1,600 members and affiliated hospitals. - Over 580 patients have ingested the M2A capsule as part of our ongoing sponsored clinical trials. Preliminary unpublished results from ongoing clinical trials support previous findings of the diagnostic yield of the M2A capsule, and consistently show the M2A capsule to produce a higher diagnostic yield than any other modality to which the capsule was compared. - Ten new distribution agreements, in Canada, Austria, Belgium, United Kingdom, Sweden, The Netherlands, Brazil, Puerto Rico, China and Taiwan, bringing the Company's global distribution coverage to 22 countries by the end of 2001. Our distributors in China and Taiwan are required to receive government clearance before marketing and selling the Given System.
