assigning an exception handler in a library

I have written an exception handler that needs to be used by multiple programs, so I put it in a bpl.  However, when I try to assign the exception handler in the program like this:

Application.OnException := MyLibrary.ExceptHandler;

Select allOpen in new window

I get "Incompatible types: 'method pointer and regular procedure'". I understand that method pointers and regular procedures are different, but I don't know how to declare the exception handler in the library so it's a method pointer. I tried putting it in a class in the library, but this didn't make a difference.
Thanks in advance for your help.
