Anti-matter is not an exception to the law of conservation (I assume you mean conservation of energy). When anti-matter comes into contact with matter, they both convert each other into energy.
It is not possible to measure location with infinite accuracy.
You can measure it with an arbitrarily small error, but not zero error. If error in location is zero, then error_location * error_momentum = 0, which is impossible.

Except nature created dirt and water too.
