DSM-IV criteria.

2. Have any significant, active medical or psychiatric illnesses (other than drug
dependence) which might inhibit their ability to complete the study or might be
complicated by administration of study medications.

3. Have clinically significant abnormal laboratory measurements in liver function tests
(AST and ALT levels greater than 3 times the upper limit of normal), hematology (CBC,
differential, platelet count), serum chemistries (SMA-24) and urinalysis at screening.

4. Test positive on the HIV blood screen.

5. Have a history of significant hepatic, renal, endocrine, cardiac, nervous,
psychiatric, gastrointestinal, pulmonary, hematologic or metabolic disorders.
