Is my non-compete and non-solicitation agreement enforceable?

I signed a 24 month non-compete and non-solicitation agreement with company A in 2006. In 2007 I formed company B which then hired all of company A's employees and provided all the services that an employment service would generally provide for company A. No employee received any pay from company A after 2007. Company A received payables, provided delivery trucks and processing facility. Company A would deposit money into Company B's account which would them pay expenses. In December of 2010, I was let go from company B and started another business which included former customers of company A. Seeing that I have not received a paycheck from company A since 2006 and did not sign a non-compete agreement with company B, is my first non-compete/solicitation agreement enforceable?
