Can you ID these artists from the signatures?

I got the attached sketches at a convention back in 2005. Can anyone ID the artists from the signatures?

The second one matches Jamal Igle's signature. As seen here:

The first one looks like it says 'Mark' but I can't figure out who that could be or the style - even tho it's familiar.
