other place in the United States of America as the registered holder hereof
shall be designated to the Company in writing.

      The principal amount hereof and interest due at maturity will be paid upon
maturity in immediately available funds against presentation of this Note at the
office of the Issuing and Paying Agent in New York, New York (as of the date of
this Note, such office being located at 111 Wall Street, New York, New York),
or at such other office or agency of the Company as the Company shall designate
by written notice to the registered holder of this Note. The Company may treat
the person in whose name this Note is registered as the owner of such Note for
the purpose of receiving payments of principal and interest on this Note and for

other obligations and indebtedness secured thereby so long as such other
obligations and indebtedness shall be so secured. The agreement of the Company

      incurred in the ordinary course of business not exceeding $50,000,000 in

      electric lines, telegraph and telephone lines and other similar purposes,
      or zoning or other restrictions as to the use of real properties, which
      encumbrances, easements, reservations, rights and restrictions do not in
      the aggregate materially detract from the value of said properties or
      materially impair their use in the operation of the business of the
      Company or any subsidiary thereof owning the same; and

            (xi) any extension, renewal or replacement (or successive
      extensions, renewals or replacements), in whole or in part, of any lien,
      charge or pledge referred to in the foregoing clauses (i) to (vi)
      inclusive of this paragraph, provided, however, that the amount of any and
      all obligations and indebtedness secured thereby shall not exceed the
      amount thereof so secured immediately prior to the time of such extension,
      renewal or replacement and that such extension, renewal or replacement
      shall be limited to all or a part of the property which secured the charge
      or lien so extended, renewed or replaced (plus improvements on such
      property).
