Validity of H1b stamped in 2008

My H1b visa was stamped in 2008 and I was in US from Feb 2009 till June 2010.
I am currently in US for few months on L1b visa from a different company. Is my H1b visa still valid for use now?

Yes, you can re-capture unused H1B period and apply as cap exempt. Read H1B Recapture Duration and Official Rule
