as security for any and all obligations of the Company under the Indenture, this
Supplemental Indenture and the Related Issue of Securities, including but not

Quarterly Note is not a business Day, then payment of the interest payable on
such date will be made on the next succeeding day that is a Business Day (and
without any interest or payment in respect of any such delay) with the same
force and effect as if made on the date the payment was originally payable.

which banking institutions in New York, New York are authorized or obligated by
law or executive order to remain closed or (iii) a day on which the Corporate
Trust Office is closed for business.

         Payment of principal of, premium, if any, and interest on the

transfer of immediately available funds to the Holder of such Global Security,
provided that, in the case of payments of principal and premium, if any, such
Global Security is first surrendered to the Paying Agent (as defined in the
Senior Indenture). If any of the securities of this series are not longer
represented by a Global Security, (i) payments of principal, premium, if any,
and interest due at the Stated Maturity or earlier redemption of such Securities
shall be made at the office of the Paying Agent upon surrender of such
Securities to the Paying Agent, and (ii) payments of interest shall be made, at
the option of the Company, subject to such surrender where applicable, (A) by
check mailed to the address of the Person entitled thereto as such address shall
appear in the Security Register or (B) by wire transfer at such place and to
such account at a banking institution in the United States as may be designated
in writing to the Trustee at least sixteen (16) days prior to the date for
payment by the Person entitled thereto.

         UNTIL THE RELEASE DATE (AS DEFINED ON THE REVERSE HEREOF), THIS SENIOR
SECURED INSURED QUARTERLY NOTE SHALL BE SECURED BY FIRST MORTGAGE BONDS (THE
"FIRST MORTGAGE BONDS") ISSUED AND DELIVERED BY THE COMPANY TO THE SENIOR
TRUSTEE (AS DEFINED ON THE REVERSE HEREOF) UNDER THE COMPANY'S TWENTY-NINTH
SUPPLEMENTAL INDENTURE DATED AS OF JULY 15, 1989, PROVIDING FOR THE RESTATEMENT
OF THE INDENTURE OF MORTGAGE AND DEED OF TRUST DATED AS OF MARCH 1, 1994 BETWEEN
THE COMPANY AND CITIBANK, N.A. (THE "MORTGAGE TRUSTEE") AND ROBERT T. KIRCHNER

INDENTURE (AS SO SUPPLEMENTED, THE "MORTGAGE INDENTURE"). ON THE RELEASE DATE,
THE SENIOR SECURED INSURED QUARTERLY NOTES SHALL CEASE TO BE SECURED BY SUCH
FIRST MORTGAGE BONDS AND, AT THE COMPANY'S OPTION, EITHER (i) SHALL BECOME
UNSECURED GENERAL OBLIGATIONS OF THE COMPANY OR (ii) SHALL BE SECURED BY FIRST
MORTGAGE BONDS UNDER A SECURED MORTGAGE INDENTURE OTHER THAN THE MORTGAGE
INDENTURE.

         Reference is made to the further provisions of this Senior Secured
Insured Quarterly Note set forth on the reverse hereof. Such further provisions
shall for all purposes have the same effect as though fully set forth at this
place.

         This Senior Secured Insured Quarterly Note shall not be valid or become
obligatory for any purpose until the certificate of authentication hereon shall
have been manually signed by the Senior Trustee under the Senior Indenture
referred to on the reverse hereof.

on or after June 1, 2004 at a Redemption Price equal to 100% of the principal
amount to be redeemed plus accrued but unpaid interest to the Redemption Date.

         In the event of redemption of the Senior Secured Insured Quarterly
Notes in part only, a new Senior Secured Insured Quarterly Note or Notes for the
unredeemed portion will be issued in the name or names of the Holders thereof
upon the surrender thereof.

         The Senior Secured Insured Quarterly Notes will not have a sinking
fund.

         Notice of redemption shall be given as provided in Section 12.4 of the
Indenture.

         Any redemption of less than all of the Senior Secured Insured Quarterly
Notes shall, with respect to the principal thereof, be divisible by $1,000.

         (f) Redemption at the Holder's Option. For purposes of this provision a
"Beneficial Owner" means the Person who has the right to sell, transfer or
otherwise dispose of an interest in Senior Secured Insured Quarterly Notes and
the right to receive the proceeds therefrom, as well as the interest and
principal payable to the Holder thereof. In general, a determination of
beneficial ownership in the Senior Secured Insured Quarterly Notes will be
determined by the Company, in its sole discretion, which determinations shall be
final and binding on all parties.

         Unless the Senior Secured Insured Quarterly Notes have been declared
due and payable prior to their maturity by reason of an Event of Default, the
personal representative or other Person authorized to represent the estate of
the deceased Beneficial Owner or from a surviving joint tenant(s) or tenant(s)
by the entirety (each, a "Representative") of a deceased Beneficial



   14



Owner has the right to request redemption prior to Stated Maturity of all or
part of such interest, expressed in integral multiples of $1,000 principal
amount, in the Senior Secured Insured Quarterly Notes, and the Company will
redeem the same subject to the limitations that the Company will not be
obligated to redeem, during the period from the Original Issue Date through and
including June 1, 2000 (the "Initial Period"), and during any twelve-month
period which ends on and includes each June 1, thereafter (each such
twelve-month period being hereinafter referred to as a "Subsequent Period"), (i)
on behalf of a deceased Beneficial Owner any interest principal amount of
$25,000 or (ii) interests in the Senior Secured Insured Quarterly Notes in an
aggregate principal amount exceeding $1,650,000. A request for redemption may
initiated by the Representative of a deceased Beneficial Owner at any time and
in any principal amount in integral multiples of $1,000. Representatives of
deceased Beneficial Owners must make arrangements with the Participant through
whom such interest is owned in order that timely presentation of redemption
requests can be made by the Participant to the Senior Trustee. If the Company,
although not obligated to do so, chooses to redeem interests of any deceased
Beneficial Owner in the Senior Secured Insured Quarterly Notes in the Initial
Period or any Subsequent Period in excess of the $25,000 limitation, such
redemption, to the extent that it exceeds the $25,000 limitation for any
deceased Beneficial Owner, shall not be included in the computation of the
$1,650,000 limitation for such initial Period or such Subsequent Period, as the
case may be, or for any succeeding Subsequent Period. Any Senior Secured Insured
Note (or portion thereof) tendered pursuant to the redemption request may be
withdrawn by a written request by the Representative received by the Senior
Trustee at least 10 days prior to its repayment.

         Subject to the $25,000 and $1,650,000 limitations, the Company will,
after the death of any Beneficial Owner, redeem the interest of such Beneficial
Owner in the Senior Secured Insured Quarterly Notes within 60 days following
receipt by the Senior Trustee of a redemption request. The Senior Trustee will
notify the Company promptly after receipt of any redemption request and the
Company will provide all funds necessary for such redemption prior to the date
of redemption to the Paying Agent. If redemption requests exceed the aggregate
principal amount of interests in Senior Secured Insured Quarterly Notes required
to be redeemed during the Initial Period or during any Subsequent Period, then
such excess redemption requests will be applied in the order received by the
Senior Trustee to successive Subsequent Periods, regardless of the number of
Subsequent Periods required to redeem such interests. All redemption requests
will be redeemed in the order in which trustee receives the redemption request.
To obtain repayment pursuant to a redemption request, the Representative must
provide to the Participant (i) a written request for repayment signed by the
Representative, and such signature must be guaranteed by a member firm of a
registered national securities exchange or of the NASD or a commercial bank or
trust company having an office or correspondent in the United States, (ii)
appropriate evidence satisfactory to the Company and the Senior Trustee that (A)
the Representative has authority to act on behalf of the deceased Beneficial
Owner, (B) the death of such Beneficial Owner has occurred and (C) the deceased
was the owner of a beneficial interest in such Senior Secured Insured Quarterly
Note at the time of death, (iii) if applicable, a properly executed assigned or
endorsed, and (iv) if the beneficial interest in such Senior Secured Insured
Quarterly Note is held by a nominee of the deceased Beneficial Owner, a
certificate satisfactory to the Senior Trustee from such nominee attesting to
the deceased's ownership of a beneficial interest in such Senior



   15



Secured Insured Quarterly Note. The Participant will provide these documents to
the Senior Trustee. All questions as to the eligibility or validity of any
exercise of redemption on behalf of a deceased Beneficial Owner will be
determined by the Company, in its sole discretion, which determinations will be
final and binding on all parties.

         For purposes of this provision an interest in Senior Secured Insured
Quarterly Notes held in tenancy by the entirety, joint tenancy or by tenants in
common will be deemed to be held by a single Beneficial Owner and the death of a
tenant by the entirety, joint tenant or tenant in common will be deemed the
death of a Beneficial Owner. The death of a Person who, during his lifetime, was
entitled to subsequently all of the rights of a Beneficial Owner of an interest
in the Senior Secured Insured Quarterly Notes will be deemed the death of the
Beneficial Owner, regardless of the recordation of such interest on the records
of the Participant, if such rights can be established to the satisfaction of the
Participant and the Company.

         In the case of any redemption request which is presented pursuant to
this provision and which has not been fulfilled at the time of the Company gives
notice of its election to partially redeem Senior Secured Insured Quarterly
Notes as described in item 3 above, such interest or portion thereof shall not
be subject to redemption pursuant to such item 3 subject to redemption pursuant
to this provision.

         (g)      Special Insurance Provisions.

                  (1) Supplemental Indentures. The consent of the Insurer shall

Indenture requiring the consent of the Holders of the Senior Secured Insured
Quarterly Notes pursuant to Section 10.2 of the Senior Indenture.

                  (2) Events of Default and Remedies. Subject to Section 1.7 of
the Senior Indenture and to the Trust Indenture Act, including, without
limitation, Sections 316(a)(1) and 317(a) thereof, if an Event of Default with
respect to the Senior Secured Insured Quarterly Notes occurs and is continuing,

to the Senior Secured Insured Quarterly Notes, the obligation of the Senior
Trustee to comply with any direction to be subject to compliance with the
conditions set forth in Sections 7.3(e) of the Senior Indenture (as if
references in those Sections to Holders were references to the Insurer) and the
protections provided to the Senior Trustee by Sections 315(d)(3) of the Trust
Indenture Act shall be applicable with respect to any direction from the Insurer
given pursuant thereto (as if references in said Section to Holders were
references to the Insurer).



   16



                  (3) Insurance Policy Payment Procedures. (a) If, as of the
close of business on the second day next preceding any date on which payment of
principal or interest is due, the Senior Trustee does not have sufficient funds
for any payment of principal or interest on the due date or if the Senior
Trustee has notice that any Holder has been required to disgorge payments of
principal or interest on the Senior Secured Insured Quarterly Notes to a trustee
in bankruptcy or creditors or others pursuant to a final judgement by a court of
competent jurisdiction that such payment constitutes an avoidable preference to
such Holder within the meaning of any applicable bankruptcy laws, then the
Senior Trustee shall notify the Insurer or its designee of such fact by
telephone or telegraph notice, confirmed in writing by registered or certified
mail.

                  (b) The Senior Trustee is hereby irrevocably designated,
appointed, directed and authorized to act as attorney-in-fact for Holders of the
Senior Secured Insured Quarterly Notes as follows:

                           (i) If and to the extent there is a deficiency in
                  amounts required to pay interest on the Senior Secured Insured
                  Quarterly Notes, the Senior Trustee shall (x) execute and

                  deficiency relates and which are paid by the Insurer, (y)
                  receive as designee of the respective Holders (and not as
                  Senior Trustee) in accordance with the tenor of the Policy
                  payment from the Insurance Paying Agent with respect to the
                  claims for interest to assigned, and (z) disburse the same to
                  such respective Holders; and

                  required to pay principal of the Senior Secured Insured
                  Quarterly Notes, the Senior Trustee shall (x) execute and
                  deliver to the Insurance Paying Agent in form satisfactory to
                  the Insurance Paying Agent an instrument appointing the
                  Insurer as agent for such Holders in any legal proceeding
                  relating to the payment of such principal and an assignment to
                  the Insurer of any of the Senior Secured Insured Quarterly
                  Notes surrendered to the Insurance Paying Agent to the extent
                  of the principal amount thereof as has not previously been
                  paid or for which moneys are not held by the Senior Trustee
                  and available for such payment (but such assignment shall be
                  delivered only if payment from the Insurance Payment Agent is
                  received), (y) receive as designee of the respective Holders
                  (and not as Trustee) in accordance with the tenor of the
                  Policy payment therefor from the Insurance Paying Agent, and
                  (z) disburse the same to such Holders.

                  (c) Payments with respect to claims for interest on and
principal of Senior Secured Insured Quarterly Notes disbursed by the Senior
Trustee from proceeds of the Policy shall not be considered to discharge the
obligation of the Company with respect to such Senior Secured Insured Quarterly
Notes, and the Insurer shall become the owner of such Senior Secured Insured


   17



Quarterly Notes and claims for the interest thereon in accordance with the tenor
of the assignment made to it under the provisions of this subsection or
otherwise.

                  (d) Irrespective of whether any such assignment is executed
and delivered, the Company and the Senior Trustee hereby agree for the benefit
of the Insurer that,

                           (i) They recognize that to the extent the Insurer
                  makes payments, directly or indirectly (as by paying through
                  the Senior Trustee), on account of principal of or interest on
                  the Senior Secured Insured Quarterly Notes, the Insurer will
                  be subrogated to the rights of such Holders to receive the
                  amount of such principal and interest from the Company, with

                           (ii) They will accordingly pay to the Insurer the
                  amount of such principal and interest (including principal and
                  interest recovered under subparagraph (ii) of the first
                  paragraph of the Policy, which principal and interest shall be
                  deemed past due and not to have been paid), with interest
                  thereon as provided in the Senior Indenture and the Senior
                  Secured Insured Quarterly Note, but only from the sources and
                  in the manner provided herein for the payment of principal of
                  and interest on the Senior Secured Insured Quarterly Notes of
                  Holders, and will otherwise treat the Insurer as the owner of
                  such rights to the extent of the amount of such principal and
                  interest.

                  (4) Application of Term "Outstanding" to Senior Secured
Insured Quarterly Notes. In the event that the principal and/or interest due on
the Senior Secured Insured Quarterly Notes shall be paid by the Insurer pursuant
to the Policy, the Senior Secured Insured Quarterly Notes shall remain

or otherwise satisfied and not be considered paid by the Company, and the Senior
Indenture and all covenants, agreements and other obligations of the Company to
the Holders of Senior Secured Insured Quarterly Notes shall continue to exist
and such covenants, agreements and other obligations shall run to the benefit of
the Insurer, and the Insurer shall be subrogated to the rights of such Holders
to the extent of such payment.

                  (5) Insurer as Third Party Beneficiary. To the extent that the
Senior Indenture confers upon or gives or grants to the Insurer any right,
remedy or claim under or by reason of the Senior Indenture, the Insurer is

notwithstanding anything in the Senior Indenture to the contrary, but only so
long as the Policy shall be in full force and effect and the Insurer is not in
default thereunder.

                  (8) Amendments or Supplements. The Senior Trustee, in
determining whether any amendments or supplements to the Senior Indenture may be
made without the consent of the Holders, or in determining whether any action
should be taken, shall consider the effect of such action on the rights of the
Holders as if the Policy were not in effect.

     MICHIGAN CONSOLIDATED GAS COMPANY, a corporation duly organized and

date will be made on the next succeeding day that is a Business Day (and without
any interest or payment in respect of any such delay) with the same force and
effect as if made on the date the payment was originally payable. "Business Day"

   25



Agent (as defined in the Senior Indenture). If any of the Securities of this
series are not longer represented by a Global Security, (i) payments of
principal, premium, if any, and interest due at the Stated Maturity or earlier
redemption of such Securities shall be made at the office of the Paying Agent
upon surrender of such Securities to the Paying Agent, and (ii) payments of
interest shall be made, at the option of the Company, subject to such surrender
where applicable, (A) by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register or (B) by wire
transfer at such place and to such account at a banking institution in the
United States as may be designated in writing to the Trustee at least sixteen
(16) days prior to the date for payment by the Person entitled thereto.

     UNTIL THE RELEASE DATE (AS DEFINED ON THE REVERSE HEREOF), THIS SENIOR NOTE
SHALL BE SECURED BY FIRST MORTGAGE BONDS (THE "FIRST MORTGAGE BONDS") ISSUED AND
DELIVERED BY THE COMPANY TO THE SENIOR TRUSTEE (AS DEFINED ON THE REVERSE
HEREOF) UNDER THE COMPANY'S TWENTY-NINTH SUPPLEMENTAL INDENTURE DATED AS OF JULY
15, 1989, PROVIDING FOR THE RESTATEMENT OF THE INDENTURE OF MORTGAGE AND DEED OF

of principal or interest on the due date or if the Senior Trustee has notice
that any Holder has been required to disgorge payments of principal or interest
on the Senior Notes to a trustee in bankruptcy or creditors or others pursuant
to a final judgement by a court of competent jurisdiction that such payment
constitutes an avoidable preference to such Holder within the meaning of any
applicable bankruptcy laws, then the Senior Trustee shall notify the Insurer or
its designee of such fact by telephone or telegraph notice, confirmed in writing
by registered or certified mail.

         (b) The Trustee is hereby irrevocably designated, appointed, directed
and authorized to act as attorney-in-fact for Holders of the Senior Notes as
follows:

             1. If and to the extent there is a deficiency in amounts required
         to pay interest on the Senior Notes, the Senior Trustee shall (x)
         execute and deliver to the Insurance Paying Agent, in form satisfactory
         to the Insurance Paying Agent, an instrument appointing the Insurer as
         agent for such Holders in any legal proceeding related to the payment
         of such interest and an assignment to the Insurer of the claims for
         interest to which such deficiency relates and which are paid by the
         Insurer, (y) receive as designee of the respective Holders (and not as
         Senior Trustee) in accordance with the tenor of the Policy payment from
         the Insurance Paying Agent with respect to the claims for interest to
         assigned, and (z) disburse the same to such respective Holders; and

             2. If and to the extent of a deficiency in amounts required to pay
         principal of the Senior Notes, the Senior Trustee shall (x) execute and
         deliver to the Insurance Paying Agent in form satisfactory to the
         Insurance Paying Agent an instrument appointing the Insurer as agent
         for such Holders in any legal proceeding relating to the payment of
         such principal and an assignment to the Insurer of any of the Senior
         Notes surrendered to the Insurance Paying Agent to the extent of the
         principal amount thereof as has not previously been paid or for which
         moneys are not held by the Senior Trustee and available for such
         payment (but such assignment shall be delivered only if payment from
         the Insurance Payment Agent is received), (y) receive as designee of
         the respective Holders (and not as Trustee) in accordance with the
         tenor of the Policy payment therefor from the Insurance Paying Agent,
         and (z) disburse the same to such Holders.




   30



         (c) Payments with respect to claims for interest on and principal of
Senior Notes disbursed by the Senior Trustee from proceeds of the Policy shall
not be considered to discharge the obligation of the Company with respect to
such Senior Notes, and the Insurer shall become the owner of such Senior Notes
and claims for the interest thereon in accordance with the tenor of the
assignment made to it under the provisions of this subsection or otherwise.

         (d) Irrespective of whether any such assignment is executed and
delivered, the Company and the Senior Trustee hereby agree for the benefit of
the Insurer that,

             1. They recognize that to the extent the Insurer makes payments,
         directly or indirectly (as by paying through the Senior Trustee), on
         account of principal of or interest on the Senior Notes, the Insurer
         will be subrogated to the rights of such Holders to receive the amount
         of such principal and interest from the Company, with respect thereon
         as provided and solely from the sources stated in the Senior Indenture
         and the Senior Notes; and

             2. They will accordingly pay to the Insurer the amount of such
         principal and interest (including principal and interest recovered
         under subparagraph (ii) of the first paragraph of the Policy, which
         principal and interest shall be deemed past due and not to have been
         paid), with interest thereon as provided in the Senior Indenture and
         the Senior Note, but only from the sources and in the manner provided
         herein for the payment of principal of and interest on the Senior Notes
         of Holders, and will otherwise treat the Insurer as the owner of such
         rights to the extent of the amount of such principal and interest.

         (4) Application of Term "Outstanding" to Senior Notes. In the event
that the principal and/or interest due on the Senior Notes shall be paid by the
Insurer pursuant to the Policy, the Senior Notes shall remain Outstanding for
all purposes of the Senior Indenture, not be considered defeased or otherwise
satisfied and not be considered paid by the Company, and the Senior Indenture
and all covenants, agreements and other obligations of the Company to the
Holders of Senior Notes shall continue to exist and such covenants, agreements
and other obligations shall run to the benefit of the Insurer, and the Insurer
shall be subrogated to the rights of such Holders to the extent of such payment.

         (5) Insurer as Third Party Beneficiary. To the extent that the Senior
Indenture confers upon or gives or grants to the Insurer any right, remedy or
claim under or by reason of the Senior Indenture, the Insurer is hereby
explicitly recognized as being a third-party beneficiary hereunder and may
enforce any such right, remedy or claim conferred, given or granted hereunder.

         (6) Notices. Any notice that is required to be given to a Holder of the
Senior Note or to the Trustee pursuant to the Senior Indenture shall also be
provided to the Insurer. All notices required to be given to the Insurer under
the Senior Indenture shall be in writing and shall be sent by registered or
certified mail addressed to MBIA Insurance Corporation, 113 King Street, Armonk,
New York 10504, Attention: IPM-DCF.




   31



         (7) These Special Insurance Provisions shall apply notwithstanding
anything in the Senior Indenture to the contrary, but only so long as the Policy
shall be in full force and effect and the Insurer is not in default thereunder.

         (8) Amendments or Supplements. The Senior Trustee, in determining
whether any amendments or supplements to the Senior Indenture may be made
without the consent of the Holders, or in determining whether any action should
be taken, shall consider the effect of such action on the rights of the Holders
as if the Policy were not in effect.

     (s) Security; Release Date. Prior to the Release Date (as hereinafter
defined), the Senior Notes shall be secured by First Mortgage Bonds designated
as Collateral Bonds, Series D (the "Collateral Bonds"), delivered by the Company
to the Senior Trustee for the benefit of the Holders of the Senior Notes. Prior
to the Release Date, the Company shall make payments of the principal of, and
premium, if any, and or interest on, the Collateral Bonds to the Senior Trustee,
which payments shall be applied by the Senior Trustee to satisfaction of all
obligations then due on the Senior Notes. Reference is made to the Mortgage
Indenture and the Senior Indenture for a description of the rights of the Senior
Trustee as holder of the Collateral Bonds, the property mortgaged and pledged
under the Mortgage Indenture and the rights of the Company and of the Mortgage
Trustee in respect thereof, the duties and immunities of the Mortgage Trustee
and the terms and conditions upon which the Collateral Bonds are secured and the
circumstances under which additional First Mortgage Bonds mays issued.

     FROM AND AFTER SUCH TIME AS ALL FIRST MORTGAGE BONDS (OTHER THAN COLLATERAL
BONDS) ISSUED UNDER THE MORTGAGE INDENTURE HAVE BEEN RETIRED THROUGH PAYMENT,
REDEMPTION OR OTHERWISE AT, BEFORE OR AFTER THE MATURITY THEREOF (THE "RELEASE
DATE"), THE COLLATERAL BONDS SHALL CEASE TO SECURE THE SENIOR NOTES IN ANY
MANNER PROVIDED THAT NO DEFAULT OR EVENT OR DEFAULT HAS OCCURRED AND AT SUCH
TIME IS CONTINUING UNDER THE SENIOR INDENTURE. IN CERTAIN CIRCUMSTANCES PRIOR TO
THE RELEASE DATE AS PROVIDED IN THE SENIOR INDENTURE, THE COMPANY IS PERMITTED
TO REDUCE THE AGGREGATE PRINCIPAL AMOUNT OF A SERIES OF COLLATERAL BONDS HELD BY
THE TRUSTEE, BUT IN NO EVENT PRIOR TO THE RELEASE DATE TO AN AMOUNT LESS THAN
THE AGGREGATE OUTSTANDING PRINCIPAL AMOUNT OF THE SERIES OF SENIOR NOTES
INITIALLY ISSUED CONTEMPORANEOUSLY WITH SUCH COLLATERAL BONDS.

     (t) Effect of Event of Default. In case an Event of Default with respect to
the Senior Notes shall occur and be continuing, the unpaid principal of the
Senior Notes may be declared due and payable, in the manner, with the effect and
subject to the conditions provided in the Senior Indenture.

     (u) Amendments and Waivers. The Senior Indenture may be modified by the
Company and the Senior Trustee without consent of any Holder with respect to
certain matters as described in


   32



the Indenture. In addition, the Senior Indenture permits, with certain
exceptions as therein provided, the amendment thereof and the modification of
the rights and obligations of the Company and the rights of the Holders of the
Senior Note of each series to be affected under the Senior Indenture at any time
by the Company and the Senior Trustee with the consent of the Holders of a
majority in principal amount of the Senior Notes at the time Outstanding of each
series to be affected. The Senior Indenture also contains provisions permitting
the Holders of a majority in principal amount of the Senior Note of each series
at the time Outstanding, on behalf of the Holders of all Senior Notes of such
series, to waive compliance by the Company with certain provisions of the Senior
Indenture and certain past defaults under the Senor Indenture and their
consequences. Any such consent or waiver by the Holder of this Senior Note shall
bind such Holder and all future Holders of this Senior Note and of any note
issued upon the registration of transfer hereof or in exchange hereof or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Senior Note.

     (v) Obligations of Company. No reference herein to the Senior Indenture and
no provision of this Senior Note or of the Senior Indenture shall alter or
impair the obligation of the Company, which is absolute and unconditional, to
pay the principal of and any premium, if any, and interest on this Note at the
time, place, and rate and in the coin or currency herein prescribed.

     (w) Denominations, Transfer and Exchange. (1) The Senior Notes are issuable
only in registered form without coupons in denominations of $25 and any integral
multiple thereof. As provided in the Senior Indenture and subject to certain
limitations therein set forth, Senior Notes of this Series are exchangeable for
a like aggregate principal amount of Senior Notes of this series of a different
authorized denomination, as requested by the Holder surrendering the same.

         (2) As provided in the Senior Indenture and subject to certain
limitations therein set forth, the transfer of this Senior Note is registrable
in the Security Register, upon surrender of this Senior Note for registration of
transfer at the office or agency of the Company in any place where the principal
of (and premium, if any) and interest on this Senior Note are payable, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Senior Notes of this series, and of like tenor, of authorized

to close.

         The bonds represented by this certificate, of the series hereinafter
specified, are bonds of the Company (herein called the "bonds") known as its
"First Mortgage Bonds", issued and to be



   39

issued in one or more series under, and all equally and ratably secured by, an
Indenture of Mortgage and Deed of Trust dated as of March 1, 1944, duly executed
by the Company to City Bank Farmers Trust Company (now known as Citibank, N.A.,
successor trustee, as "Mortgage Trustee") Ralph E. Morton (Robert T. Kirchner,
successor individual trustee and, together with Citibank, N.A., the "Secured
Trustees") as restated in Part II of the Twenty-ninth Supplemental Indenture
dated as of July 15, 1989, which became effective on April 1, 1994, to which
indenture and all indentures supplemental thereto executed on and after July 15,
1989 reference is hereby made for a description of the property mortgaged and
pledged, the nature and extent of the security, the terms and conditions upon
which the bonds are, and are to be, issued and secured, and the rights of the
holders of the bonds of the Secured Trustees in respect of such security (which
indenture and all indentures supplemental thereto, including the Thirty-fifth
Supplemental Indenture dated as of June 18, 1998, are hereinafter collectively
called the "Secured Indenture"). As provided in the Secured Indenture, the bonds
may be for various principal sums and are issuable in series which may mature at
different times, may bear interest at different rates and may otherwise vary as
therein provided. The bonds represented by this certificate are part of a Series
designated "Collateral Bonds," herein called Collateral Bonds, created by the
Thirty-fifth Supplemental Indenture dated as of June 18, 1998, as provided for
in the Secured Indenture.

         With the consent of the Company and to the extent permitted by and as
provided in the Secured Indenture and the Senior Indenture, the rights and
obligations of the Company and/or the rights of the holders of the Collateral
Bonds of the thirty-second Series and/or the terms and provisions of the Secured
Indenture may be modified or altered by such affirmative vote or votes of the
holders of the Related Notes then outstanding as are specified in the Senior
Indenture.

Notes are redeemed, as provided in the Senior Indenture with respect to the
Related Notes and in the Related Notes.

Senior Indenture shall occur, the principal of the Collateral Bonds may become
or be declared due and payable in the manner, with the effect, and subject to
the conditions provided in the Secured Indenture and the Senior Indenture.

         The Senior Trustee has agreed pursuant to the Senior Indenture to hold
the Collateral Bonds as collateral for the benefit of the holders of the Related

trustee) such Collateral Bonds until the earlier of the Release Date or the
prior retirement of the Related Notes through redemption, purchase or otherwise.
"Release Date" means the date on which all First Mortgage Bonds of the Company
issued and outstanding under the Secured Indenture, other than the Collateral
Bonds (as defined in the Senior Indenture), have been retired (at, before or
after the maturity hereof) through payment, redemption or otherwise provided

Senior Indenture. On the Release Date, the Senior Trustee shall deliver to the
Company for cancellation all Collateral Bonds, and the Company shall cause the
Senior Trustee to provide notice to all holders of Related Notes of the
occurrence of the Release Date.

Related Notes. Following the Release Date, the Company shall cause the Secured
Indenture to be closed, and the Company shall issue any additional Collateral
Bonds to be issued thereunder. From and after the Release Date, the Company's
obligations in respect of the Collateral Bonds shall be satisfied and
discharged.

         No recourse shall be had for the payment of the principal of, or the
interest on, the Collateral Bonds, or for any claim based hereon or otherwise in
respect of the Collateral Bonds or the Secured Indenture, Senior Indenture or
any Indenture supplemental to either thereof, or against any incorporator,
stockholder, director or officer, past, present or future, the Company, as such,
or any predecessor or successor corporation, either directly or through the
Company or any such predecessor or successor corporation, whether by virtue of
any constitution, state or rule of law, or by the enforcement of any assessment
or penalty or otherwise, all such liability, whether at common law, in equity,
by any constitution, statute or otherwise, of incorporators, stockholders,
directors or officers being waived and released by the owner hereof and every
owner of any Related Note by the acceptance of the Collateral Bonds or such
Related Note, as the case may be, and as part of the consideration for the issue
thereof, and being likewise waived and released pursuant to the Secured
Indenture and the Senior Indenture.

         The Collateral Bonds shall not be valid or become obligatory for any
purpose unless and until the certificate of authentication hereon shall have
been manually executed by the Mortgage Trustee or its successor in trust under
the Secured Indenture.


   41

Supplemental Indenture dated as of June 18, 1998, are hereinafter collectively
called the "Secured Indenture"). As provided in the Secured Indenture, the bonds
may be for various principal sums and are issuable in series which may mature at
different times, may bear interest at different rates and may otherwise vary as
therein provided. The bonds represented by this certificate are part of a Series
designated "Collateral Bonds," herein called Collateral Bonds, created by the
Thirty-fifth Supplemental Indenture dated as of June 18, 1998, as provided for
in the Secured Indenture.

         With the consent of the Company and to the extent permitted by and as
provided in the Secured Indenture and the Senior Indenture, the rights and
obligations of the Company and/or the rights of the holders of the Collateral
Bonds of the thirty-second Series and/or the terms and provisions of the Secured
Indenture may be modified or altered by such affirmative vote or votes of the
holders of the Related Notes then outstanding as are specified in the Senior
Indenture.

         The Collateral Bonds shall be redeemed if and to the extent Related
Notes are redeemed, as provided in the Senior Indenture with respect to the
Related Notes and in the Related Notes.

         In case an event of default as defined in the Secured Indenture or the
Senior Indenture shall occur, the principal of the Collateral Bonds may become
or be declared due and payable in the manner, with the effect, and subject to
the conditions provided in the Secured Indenture and the Senior Indenture.

         The Senior Trustee has agreed pursuant to the Senior Indenture to hold
the Collateral Bonds as collateral for the benefit of the holders of the Related
Notes under all circumstances and not to transfer (except to a successor
trustee) such Collateral Bonds until the earlier of the Release Date or the
prior retirement of the Related Notes through redemption, purchase or otherwise.
"Release Date" means the date on which all First Mortgage Bonds of the Company
issued and outstanding under the Secured Indenture, other than the Collateral
Bonds (as defined in the Senior Indenture), have been retired (at, before or
after the maturity hereof) through payment, redemption or otherwise provided
that no default or event of default has occurred and is continuing under the
Senior Indenture. On the Release Date, the Senior Trustee shall deliver to the
Company for cancellation all Collateral Bonds, and the Company shall cause the
Senior Trustee to provide notice to all holders of Related Notes of the
occurrence of the Release Date.

   46

As a result, on the Release Date, the Collateral Bonds shall cease to secure the
Related Notes. Following the Release Date, the Company shall cause the Secured
Indenture to be closed, and the Company shall issue any additional Collateral
Bonds to be issued thereunder. From and after the Release Date, the Company's
obligations in respect of the Collateral Bonds shall be satisfied and
discharged.

         No recourse shall be had for the payment of the principal of, or the
interest on, the Collateral Bonds, or for any claim based hereon or otherwise in
respect of the Collateral Bonds or the Secured Indenture, Senior Indenture or
any Indenture supplemental to either thereof, or against any incorporator,
stockholder, director or officer, past, present or future, the Company, as such,
or any predecessor or successor corporation, either directly or through the
Company or any such predecessor or successor corporation, whether by virtue of
any constitution, state or rule of law, or by the enforcement of any assessment
or penalty or otherwise, all such liability, whether at common law, in equity,
by any constitution, statute or otherwise, of incorporators, stockholders,
directors or officers being waived and released by the owner hereof and every
owner of any Related Note by the acceptance of the Collateral Bonds or such
Related Note, as the case may be, and as part of the consideration for the issue
thereof, and being likewise waived and released pursuant to the Secured
Indenture and the Senior Indenture.

         The Collateral Bonds shall not be valid or become obligatory for any
purpose unless and until the certificate of authentication hereon shall have
been manually executed by the Mortgage Trustee or its successor in trust under
the Secured Indenture.
