+Exceptions
+----------
+
+.. exception:: tf2.TransformException
+
+    base class for tf exceptions.  Because :exc:`tf2.TransformException` is the
+    base class for other exceptions, you can catch all tf exceptions
+    by writing::
+
+        try:
+            # do some tf2 work
+        except tf2.TransformException:
+            print "some tf2 exception happened"
+        
+
+.. exception:: tf2.ConnectivityException
+
+   subclass of :exc:`TransformException`.
+   Raised when that the fixed_frame tree is not connected between the frames requested.
+
+.. exception:: tf2.LookupException
+
+   subclass of :exc:`TransformException`.
+   Raised when a tf method has attempted to access a frame, but
+   the frame is not in the graph.
+   The most common reason for this is that the frame is not
+   being published, or a parent frame was not set correctly 
+   causing the tree to be broken.  
+
+.. exception:: tf2.ExtrapolationException
+
+   subclass of :exc:`TransformException`
+   Raised when a tf method would have required extrapolation beyond current limits.
+
+
+.. exception:: tf2.InvalidArgumentException
+
+   subclass of :exc:`TransformException`.
+   Raised when the arguments to the method are called improperly formed.  An example of why this might be raised is if an argument is nan.
