H1B is expired- renewal under cap exempt

I got H1b visa filed through one of the consultants year 2007 & valid till Oct 2010. I have travelled on the same petition once to US on June 2008 and returned to India on Apr 2009.

My queries are:

  1. Is it possible to get the same H1b petition renewed this year 2014-15

  2. Is it eligible for Cap exempt ?.

  3. Is there any particular timeframe to file this if its valid Cap exempt. ?
