You are in pretty good shape here with 7k with blinds of 400. You can fold it here and just wait out those 8 remaining people to the money but... pocket tens are not a bad hand so I would call it here and push on a non scary flop. If UTG decides to move all in after my call I will fold.

So in short, call and hope for UTG to either call or fold. Best would be that he would fold since you have MP1 covered. Push to a non scary flop. You have position too after the flop.
