Pggy stated one.
The other one is that taking the reciprocal of both sides flips the sign.

When you say exception, if you mean what you *can* do in an inequality that you cannot do in an equality, one of the "exceptions" is multiplying/dividing by a negative number. This flips the inequality sign.
