No poles shall be erected by the grantee without the town’s prior approval, which shall not be unreasonably withheld, with regard to location, height, type and any other pertinent aspect. However, no location of any pole of the grantee shall be a vested right, and the poles shall be removed or modified by the grantee at its own expense whenever the town reasonably determines that the public convenience would be enhanced thereby. Grantee shall utilize existing poles and conduits, where possible. The town shall have the right, during the life of the franchise, to install and maintain free of charge upon the poles owned by the grantee, any wire and pole fixtures that do not unreasonably interfere with the cable system operations of the grantee; provided the town shall at all times indemnify and hold grantee harmless against any and all claims which might arise as a result of the town’s use.
