You can either start with the 3-clause BSD license or MIT license and  
add something like this from the OSL:

"6) Attribution Rights. You must retain, in the Source Code of any  
Derivative Works that You create, all copyright, patent, or trademark  
notices from the Source Code of the Original Work, as well as any  
notices of licensing and any descriptive text identified therein as an  
"Attribution Notice." You must cause the Source Code for any  
Derivative Works that You create to carry a prominent Attribution  
Notice reasonably calculated to inform recipients that You have  
modified the Original Work."

...or you might use the OSL directly if you are happy with its  
intent.  It's not commonly used as a license, but the OSL(v3) is well- 
crafted and might suit you better.  Other people might prefer the GNU  
LGPL or even plain GPL, as they also require modified versions to be  
prominently renamed and documented.
