        reviewed, discussed and signed by each potential participant before full implementation of
        screening procedures.

        Screening will include general observations, physical examination, demographics, medical
        and medication history, an electrocardiogram, sitting blood pressure and heart rate,
        respiratory rate and temperature. The physical examination will include, but may not be
        limited to, an evaluation of the cardiovascular, gastrointestinal, respiratory and central
        nervous systems.

        The screening clinical laboratory procedures will include:

          -  CLINICAL CHEMISTRY: serum creatinine, BUN, glucose, AST(GOT), ALT(GPT), albumin, total
             bilirubin, total protein, and alkaline phosphatase

          -  HIV antibody, hepatitis B surface antigen, hepatitis C antibody screens

        psychiatric disease (as determined by the clinical investigators).

        Subjects whose clinical laboratory test values are outside the accepted reference range and

        screen or a reactive HIV antibody screen.

        Subjects demonstrating a positive drug abuse screen when screened for this study.
