Both 1G and 2G LH engines are interference - damage can likely occur if the timing belt goes and you're out on the freeway...
While you don't meet the recommended mileage (105K for TB), you do exceed the 'time' factor that is also referenced (FSM?) - I believe it to be 84 months?
While it's probably not critical that you get the timing belt changed immediately, I would definitely plan on doing it soon. Of course, you'll want to do the water pump and probably the timing belt tensioner pulley.
Other items to think about at your mileage - trans fluid & filter and differential oil change.
