1. Some S are R. (I)
2. No B are S. (O)
3. All R are H. (A)
4. All M are B. (A)
5. Some H are not M. (I)
From (3), (4) and AAI-3, we can infer that some H are R. 
From (1), (2), and IEO-2, we can infer that some R are not B. 
From the above two inferences and (5), we can conclude that some H are not M. Thus, the argument is valid.
