        HIV-Related Criteria:

          -  Willingness to receive HIV test results

          -  Willingness to discuss HIV infection risks and amenable to HIV risk reduction
             counseling.

          -  Assessed by the clinic staff as being at 'low risk' for HIV infection and committed to
             maintaining behavior consistent with those criteria through the last required protocol
