kh2gr,

Depends on the relationship between company and insurance underwriter. Some insurance companies are going to require certain total times and experience as well as training requirments (such as approved sim courses). Others might only require a "signoff" from the Chief Pilot.

That said, I would say that unless you have time in type, you're going to be a hard sell for a Chief pilot to bring on board with only 10 ME. I recently looked at bringing somebody with 3500TT and 50ME onboard to fly our same type (560) as SIC and some issues came up regarding insurance. That said, the single pilot certified captain in your case might help your argument since by all rights you're not a required crewmember when flying with him... We don't have the waiver/authorization at my company since the boss/corporate policy dictates two pilots at all times.
