34. Upon the application of any interested person, the Board may, after a public inquiry announced and held in accordance with the first paragraph of section 33, and after giving the holder of the exclusive right the opportunity to be heard, compel such holder, upon such conditions as it fixes, to extend his undertaking to any part of the territory for which the exclusive right was granted to him.
It may also, upon the application of any interested person, compel the holder of the exclusive right to extend his undertaking beyond the territory for which such right was granted to him; the order may be made only after the proceedings contemplated in the preceding paragraph have been had and if the Government, upon the recommendation of the Board, has extended the territory for which the exclusive right had been granted.
In both cases, the Board must make certain that the profitability and the efficiency of the undertaking will not be impaired as a result of its decision.
