mortgaged and pledged, the nature and extent of the security,  the rights of the
holders  of the bonds and of the  Trustee  in  respect  thereof,  the duties and
immunities of the Trustee, the terms and conditions upon which the bonds are and
are to be secured,  and the  circumstances  under which  additional bonds may be
issued.  With the consent of the Company and to the extent  permitted  by and as
provided in the Mortgage,  the rights and  obligations of the Company and/or the
rights of the  holders  of the bonds  and/or  the  terms and  provisions  of the
Mortgage  may be  modified or altered by  affirmative  vote of the holders of at
least seventy per centum (70%) in principal amount of the bonds then outstanding
under the  Mortgage  and, if the rights of the holders of one or more,  but less
than all,  series of bonds then  outstanding  are to be  affected,  then also by
affirmative  vote of the  holders  of at  least  seventy  per  centum  (70%)  in
principal  amount of the bonds then outstanding of each series of bonds so to be
affected  (excluding in any case bonds disqualified from voting by reason of the

the consent of the holder  hereof,  no such  modification  or alteration  shall,
among other things,  impair or affect the right of the holder to receive payment
of the principal of and interest on this bond and other amounts, if any, payable
upon the  redemption  hereof on or after  the  respective  due  dates  expressed
herein,  or permit  the  creation  of any lien equal or prior to the lien of the
Mortgage  or deprive the holder of the  benefit of a lien on the  mortgaged  and
pledged property.

         The Company has issued One Hundred  Million Dollars  ($100,000,000)  in
aggregate  principal  amount of its 6-3/4%  Senior  Notes Due 2006 (the  "Senior

November  15, 1996 (the "Senior  Note  Indenture"),  between the Company and The

Senior  Note  Indenture  being  hereinafter  referred  to as  the  "Senior  Note
Trustee"),  as supplemented  by the First  Supplemental  Indenture,  dated as of
November 15,  1996,  between the Company and the Senior Note Trustee (the "First
Supplemental Indenture").

         The Company has issued the bonds of this series to secure the Company's
obligation to pay principal,  premium,  if any, and interest on the Senior Notes

         The  Company's   obligation  to  make  payments  with  respect  to  the
principal, premium and/or interest on the bonds of this series shall be fully or
partially,  as the case may be,  satisfied and discharged to the extent that, at
the time  that any  such  payment  shall be due,  the  corresponding  amount  of
principal of, premium,  if any, and/or interest then due on the Senior Notes Due
2006 shall have been fully or partially paid, as the case may be, or there shall
have been  deposited  with the Senior  Note  Trustee  pursuant  to Section  501,

Indenture,  bonds of this series in a principal  amount  equal to the  principal
amount of Senior Notes Due 2006 so paid or for which such
                                        2

provision  for payment has been made shall be deemed fully paid,  satisfied  and
discharged and the obligations of the Company thereunder shall be terminated and
such bonds of this series shall be  surrendered to and cancelled by the Trustee.
From and after such date as all bonds  issued  under the  Mortgage  (other  than
Senior  Note First  Mortgage  Bonds,  as such term is defined in the Senior Note
Indenture)  have been retired  through  payment,  redemption,  or otherwise  at,
before or after maturity thereof (the "Release Date"),  the bonds of this series
shall be deemed fully paid,  satisfied and  discharged and the obligation of the
Company  hereunder  shall be terminated.  On the Release Date, the bonds of this
series shall be surrendered to and cancelled by the Trustee.

         This  bond  is  transferable  as  prescribed  in  the  Mortgage  by the
registered owner hereof in person,  or by his duly authorized  attorney,  at the
office or agency of the Company or at the office or agency of the Company in the
Borough  of  Manhattan,  The City of New York,  New  York,  upon  surrender  and
cancellation of this bond, and thereupon a new fully registered bond of the same
series for a like principal  amount will be issued to the transferee in exchange
herefor as provided in the Mortgage.

         In the manner  prescribed in the Mortgage,  bonds of this series,  upon
surrender thereof,  for cancellation,  at the office or agency of the Company in
the  Borough  of  Manhattan,  The City of New York,  New York,  together  with a
written  instrument  of transfer,  if required by the Company or by the Trustee,
duly executed by the registered  owner or by his duly authorized  attorney,  are
exchangeable  for a like aggregate  principal amount of bonds in registered form
of the same series of other authorized  denominations.  Bonds of this series are
issuable in  denominations  of One Thousand  Dollars or any  integral  multiples
thereof.

         No service charge shall be made for any such transfer or exchange,  but
the Company may  require  the  payment of a sum  sufficient  to cover any tax or
other governmental charge payable in connection therewith.

         The bonds of this series shall be redeemed,  in whole or in part,  from
time to time, on the date on which a  corresponding  principal  amount of Senior
Notes Due 2006 are  redeemed,  as provided in the Senior Note  Indenture and the
First Supplemental  Indenture upon the Senior Note Trustee's notification of the
Trustee of such redemption, at a redemption  price equal to the redemption price
of such  Senior  Notes Due 2006  being so  redeemed . Any such  notice  shall be
received by the Trustee no later than 5 days prior to any redemption  date fixed
for the bonds of this series to be  redeemed  and shall  specify  the  principal
amount of such bonds of this series to be redeemed, the redemption date, and the
amount of accrued interest and premium, if any, to be paid thereon.  The Company

money sufficient to pay the principal amount including accrued interest, if any,
and  premium,  if  any,  on the  bonds  of  this  series  to be  redeemed.  Upon
presentation  to the  Trustee  of any bonds of this  series by the  Senior  Note
Trustee for payment,  such bonds of this series so  presented  shall be redeemed
and paid in full.

         In the event the principal of all Senior Notes Due 2006 is declared due
and payable or becomes  automatically due and payable pursuant to Section 602 of
the Senior Note Indenture,  upon the filing with the Trustee of a written demand
for the  acceleration  of the payment of principal of all the bonds,  such bonds
shall become immediately due and payable.

         Redemption  of the  bonds of this  series  shall be  effected,  without
further  notice by the Company to the Trustee,  by the payment by the Company of
the applicable  redemption  price  specified in this bond at the place specified
for payment of principal of and interest on such bonds.
                                       3

         The Senior  Note  Series A Bonds will not be subject to  prepayment  or
redemption  prior to maturity  except as provided  herein,  notwithstanding  the
provisions  of Section 39 or Section 64 of the  Mortgage,  or with  "Proceeds of
Released Property," as defined in the Mortgage.

         The bonds of this series will not be subject to any sinking fund.

         The Company  covenants and agrees that,  prior to Release Date, it will
not take any action  (except  as  described  in this bond) that would  cause the
outstanding  principal  amount of the  bonds of this  series to be less than the
then outstanding principal amount of the Senior Notes Due 2006.

         The Company and the Trustee may deem and treat the person in whose name
this  bond is  registered  as the  absolute  owner  hereof  for the  purpose  of
receiving  payment and for all other  purposes,  and neither the Company nor the
Trustee shall be affected by any notice to the contrary.

         No  recourse  shall  be had  for the  payment  of the  principal  of or
interest on this bond against any  incorporator  or any past,  present or future
subscriber to the capital stock, stockholder, officer or director of the Company
or of any  predecessor or successor  corporation,  as such,  either  directly or
through the Company or any predecessor or successor corporation,  under any rule
of law,  statute or  constitution  or by the  enforcement  of any  assessment or
otherwise,  all such  liability  of  incorporators,  subscribers,  stockholders,
officers  and  directors  being  released  by the holder or owner  hereof by the
acceptance of this bond and being  likewise  waived and released by the terms of
the Mortgage.
