Do not use sed to edit a dumpfile. Use a tool designed for the task, like svndumptool.

Because this repository is now different than it was before (the history has been edited), you must give the new repository a new UUID.
svnadmin load --ignore-uuid Example2 < Example1-edited.dump
Since the UUID has changed, everyone must check out new working copies; it is not possible to update or switch existing working copies to this new changed repository.
