new owners - plan termination

[Santo Gold]

A small business sells to a larger business.  The new owners have their own 401k plan.

The small business 401k plan and business fiscal year are 7/1 - 6/30.  The business was sold on October 1.  The status of the small biz 401k plan was not addressed in the sales agreement (crazy, i know.  We just found out about the sale today, almost 2 months later).

Theres more involved but an initial question:  Who would make the decisions on if/when to terminate the small biz 401k (I do not believe a plan merger is being considered)?  The plan document and trust agreement still show the small biz owners as the trustee.  

Thank  you
