protocol OR subjects with less than thirty percent decrease in angiomyolipomas at the
end of 12 months on study drug but with documented improvement, or stabilization, of
baseline clinical status per physical, pulmonary function and/or laboratory

of 12 months on study drug on the initial RAD001 study.

- Significant hematologic or hepatic abnormality (i.e. ALT and AST >2.5x ULN), serum
albumin <3 g/dl, HCT <30%, platelets <75,000/cumm, adjusted absolute neutrophil count
<1,000/cumm, total WBC <3,000/cumm).

- Continuous requirement for supplemental oxygen.

- Intercurrent infection at initiation of RAD001.

- Embolization of angiomyolipoma within one month; any other recent surgery (within 2
months of initiation of RAD001).
