          2. Signed informed consent indicating that patients are aware of the investigational
             nature of this study prior to participation in the study and any related procedures
             being performed.

          4. Prior therapy with growth factor support, lenalidomide, 5-azacytidine, decitabine or
             other investigational agents is allowed if last dose was given more than 14 days prior
             to first dose of LBH 589.

          5. Previously untreated patients are eligible for this study.

          6. Patients must meet the following laboratory criteria: AST/SGOT and ALT/SGPT </= 2.5 x
             upper limit of normal (ULN) or </= 5.0 x ULN if the transaminase elevation is due to
             leukemic involvement; Serum bilirubin </= 1.5 x ULN; Serum creatinine </= 1.5 x ULN or

             serum ionized calcium >/= LLN; Serum magnesium >/= LLN; TSH and free T4 within normal
             limits (WNL) (patients may be on thyroid hormone replacement)

          7. Baseline MUGA or ECHO must demonstrate LVEF >/= the lower limit of the institutional
             normal of 50%.
