Unless he has 98 or 2s2h, I think you're ahead. I would assume most aggressive players dont like limping with middle pocket pairs and would raise preflop. I think he's much more likely to have JT, QT, Face9 or an overpair way more often than he has 98, 92, or a set.

Edit: oops didnt see EP limp and thought it was blind vs blind battle. I think that makes overpairs less likely and 99, 88 more likely, but I still think you're ahead of his range.
