Well, the character set is 26+26 = 52. Ten characters is 52^10 = 144,555,105,949,057,024 possible passwords. At 10m/sec (which is very low depending on the hash), ~458 years.
BUT...10m/sec is low for many types of hashes*, even using a cpu. Also, wordlists, if it is based on a dictionary word, are many times more efficient than brute forcing it.
As for the mask, just use a variable, e.g. -2 ?l?u ?2?2?2?2?2?2?2?2?2?2

*Many, but not all. Depends on the hash.
