series of  Collateral  Trust Bonds to be known as  "Collateral  Trust
Bonds, 7.65%    Series  Due  March  28,  2000  (referred  to   herein
as "Collateral    Trust  Bonds  of  the  7.65%  Series").     The
Collateral Trust    Bonds   of  the  7.65%  Series  shall  be   executed,
authenticated and  delivered in accordance with the provisions of, and shall
in all   respects  be  subject to, all of the terms,   conditions
and covenants of the Indenture, as supplemented and modified.

           The commencement of the first interest period shall

Series shall  mature March 28, 2000, and shall bear interest  at  the
rate of   7.65%  per annum, payable semi-annually on the  28th  day
of March   and the 28th day of September in each year, commencing

defined) with   respect to any interest payment date shall be  entitled
to receive   the   interest  payable on  such  interest   payment
date notwithstanding  the  cancellation of such  Collateral   Trust
Bonds of   the 7.65% Series upon any transfer or exchange subsequent
to the   record   date   and  prior  to  such  interest   payment
date; provided,   however,  that if and to the extent  the   Company
shall default   in   the   payment of the  interest  due   on   such
interest payment   date,  such  defaulted interest  shall  be  paid  as
provided in Section 307 of the Indenture.

            The   term  "record date" as used in this  Section
with respect to any interest payment date shall mean the March 15
or September 15, as the case may be, next preceding  the  semi-
annual interest   payment  date, or, if such  March 15  or  September
15 shall   be   a  legal  holiday  or  a  day  on  which  banking
institutions in the Borough of Manhattan, The City of New York, State  of
New York  or  in  the  City  of Chicago, State  of  Illinois,  are
authorized by  law to close, then the next preceding day which shall  not

Bonds without   coupons  of  the denomination  of  $1,000,  or   any
integral multiple  of $1,000, appropriately numbered.  Subject  to  the
terms and   conditions  set forth in the Indenture,  the  Collateral
Trust Bonds   of  the 7.65% Series may be exchanged for one or  more
new Collateral   Trust   Bonds  of  the  7.65%  Series  of   other
authorized denominations,   for  the  same aggregate  principal   amount,
upon surrender  thereof to the agency of the Company in  the   City
of Chicago,  Illinois, or, at the option of the  holder,  at  the
agency of the Company in the City of New York.

            Collateral  Trust  Bonds of the 7.65%  Series  may
be exchanged  or  transferred without expense to  the  registered
owner thereof  except  that any taxes or other governmental  charges
that may  be  imposed in connection with such transfer or  exchange
shall be   paid  by  the  registered owner requesting such  transfer
or exchange   as   a  condition  precedent to  the  exercise   of
such privilege.

Series and the  Trustee's  Certificate  of  Authentication   shall
be substantially in the following forms respectively:

           [FORM OF REVERSE OF COLLATERAL TRUST BOND]

            This  Collateral  Trust Bond  is  one  of  a  duly
authorized issue   of   Collateral  Trust Bonds  of  the  Company  in  an
aggregate principal   amount  of  up  to  $50,000,000,  of  the   series

secured by    an  Indenture  of  Mortgage  and  Deed  of  Trust   (the

The First   National  Bank of Chicago, as Trustee (the "Trustee"),
as supplemented  by  three supplemental indentures  (including  a
Third Supplemental   Indenture  dated as  of  March  1,  1995)  each
executed by    the  Company  to  said  Trustee  (said  Indenture,    as
so supplemented,   being  herein  sometimes  referred    to    as
the "Indenture"),   to   which  Indenture   and   all   indentures
supplemental thereto   reference  is  hereby made  for  a  description   of
the properties  mortgaged and pledged, the nature and  extent   of
the security,  the  rights of registered owners of the  Collateral
Trust Bonds   and  of the Trustee in respect thereof, and the  terms
and conditions upon which the Collateral Trust Bonds are, and  are
to be,  secured.   The Collateral Trust Bonds may  be  issued  in
series, for   various principal sums, may mature at different   times,
may bear   interest  at  different rates and  may  otherwise  vary
as provided in the Indenture.  This Collateral Trust Bond is  one

Series Due   March   28, 2000" (the "Collateral Trust Bonds  of   the
7.65% Series") of the Company, in an aggregate principal amount   of
up to   $50,000,000,  issued under and secured by the   Indenture
and described in the Third Supplemental Indenture thereto dated as

the Company and the Trustee.

           The Collateral Trust Bonds of the 7.65% Series will

redemption price  equal  to  100% of the principal amount  thereof,  plus
accrued interest   to  the date of redemption, through the application
of cash   received  by the Trustee as a result of properties   of
the Company  being  taken by eminent domain or being  sold  to  an
entity possessing the power of eminent domain.

            In  case  an  Event  of Default,  as  defined   in
the Indenture,  shall occur, the principal of all  the  Collateral
Trust Bonds  of the 7.65% Series at any such time outstanding  under
the Indenture may be declared or may become due and payable,  upon
the conditions  and in the manner and with the effect provided  in
the Indenture.  The Indenture provides that such declaration   may
be rescinded under certain circumstances.

            No   reference  herein  to the  Indenture  and  no
provision of  this Collateral Trust Bond or of the Indenture shall alter
or impair   the  obligation  of the Company, which  is   absolute
and unconditional, to pay the principal of and premium,  if   any,
and interest   on this Collateral Trust Bond at the times,   place
and rate,   in   the   coin  or  currency, and  in   the   manner,
herein prescribed.

or transferred  without  expense to the registered  owner  hereof
except that   any  taxes or other governmental charges  that  may  be
imposed in  connection with such transfer or exchange shall be paid by
the registered  owner  requesting such  transfer  or  exchange  as
a condition precedent to the exercise of such privilege.

            Prior to due presentment of this Collateral  Trust
Bond for   registration of transfer, the Company, the Trustee   and
any agent  of  the Company or the Trustee may treat the Person  in
whose name   this   Collateral  Trust Bond  is  registered  as   the
absolute owner   hereof   for  all  purposes,  whether  or  not    this
Collateral Trust   Bond be overdue, and neither the Company, the  Trustee
nor any such agent shall be affected by notice to the contrary.

            As provided in the Indenture, no recourse shall be
had for   the  payment  of  the principal of or premium,  if  any,
or interest   on  any Collateral Trust Bonds or any part thereof,
or for   any claim based thereon or otherwise in respect thereof,
or of    the  indebtedness  represented  thereby,  or  upon   any
obligation, covenant  or  agreement  under the  Indenture,  against, and
no personal  liability whatsoever shall attach to, or be incurred
by, any   incorporator,  stockholder, officer  or   director,   as
such, past,   present or future of the Company or of any predecessor
or successor corporation (either directly or through the  Company
or a  predecessor or successor corporation), whether by virtue of
any constitutional  provision, statute or rule  of  law,   or   by
the enforcement  of  any assessment or penalty or  otherwise;   it
being expressly  agreed and understood that the Indenture  and   all
the Collateral  Trust Bonds are solely corporate  obligations  and
that any   such  personal  liability  is hereby  expressly   waived
and released  as  a condition of, and as part of the consideration
for, the  execution  of  the  Indenture and  the  issuance  of  the
Collateral Trust Bonds.
