Do anyone happen to know my situations? many thanks in advance.

Hi All, My HSMP was issued on 24/08/2007. I firstly arrived in UK on 01/10/2007 and my current visa (tier 1) expires on 24/08/2012. Will I be eligible for ILR in 07/2012 (being 5 years from date I have received HSMP), or do I have to apply for another visa extension to cover period between 24/08/201...
