PART II

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER
            MATTERS

(a)  Market for Our Common Stock

        The Company's common stock has been traded on the Nasdaq National Market tier of the Nasdaq Stock Market under the trading symbol "OMCL" since August 7, 2001. The following table sets forth for the period indicated the high and low closing sale prices for the common stock, as reported by the Nasdaq National Market. The reported last sale price of the Company's common stock on the Nasdaq National Market on February 28, 2003 was $3.00.

        The approximate number of holders of record of the shares of the Company's common stock was 411 as of February 28, 2003. This number does not include stockholders whose shares are held in trust by other entities. The actual number of stockholders is greater than this number of holders of record. Based on the number of annual reports requested by brokers, the Company estimates that it has approximately 1,900 beneficial owners of its common stock.

        The Company has never paid any cash dividends on its common stock and does not anticipate paying cash dividends in the foreseeable future. The Company has entered into a bank line of credit and the Company's agreement with such lender prohibits the payment of cash dividends without the prior written consent of the lender.

(b)  Recent Sales of Unregistered Securities

        In October 2001 the Company issued a five-year warrant to purchase 173,410 shares of the Company's common stock at an exercise price of $8.745 to Ascension Health Ventures, LLC. The sales and issuances of these securities were deemed to be exempt from registration under the Securities Act in reliance upon Regulation D.
