                                4




          SECTION 2.4    GLOBAL NOTE

principal amount equal to all Outstanding Notes, to be registered in the name 
of the Depository, or its nominee, and delivered by the Trustee to the 
Depository for crediting to the accounts of its participants pursuant to the 
instructions of the Regular Trustees.  The Company upon any such presentation 
shall execute a Global Note in such aggregate principal amount and deliver 
the same to the Trustee for authentication and delivery in accordance with 
the Indenture and this [      ] Supplemental Indenture. Payments on the Notes 
issued as a Global Note will be made to the Depository; and

          (b)  if any Preferred Securities are held in non book-entry 
certificated form, the Notes in certificated form may be presented to the 
Trustee by the Property Trustee and any Preferred Security Certificate which 
represents Preferred Securities other than Preferred Securities held by the 
Clearing Agency or its nominee ("Non Book-Entry Preferred Securities") will 
be deemed to represent beneficial interests in Notes presented to the Trustee 
by the Property Trustee having an aggregate principal amount equal to the 
aggregate liquidation amount of the Non Book-Entry Preferred Securities until 
such Preferred Security Certificates are presented to the Security Registrar 
for transfer or reissuance at which time such Preferred Security Certificates 
will be cancelled and a Note registered in the name of the holder of the 
Preferred Security Certificate or the transferee of the holder of such 
Preferred Security Certificate as the case may be, with an aggregate 
principal amount equal to the aggregate liquidation amount of the Preferred 
Security Certificate cancelled will be executed by the Company and delivered 
to the Trustee for authentication and delivery in accordance with the 
Indenture and this [      ] Supplemental Indenture.  On issue of such Notes, 
Notes with an equivalent aggregate principal amount that were presented by 
the Property Trustee to the Trustee will be deemed to have been cancelled.

          SECTION 2.5    INTEREST

          (a)  Each Note will bear interest at the rate of [  ]% per annum 
(the "Coupon Rate") from the original date of issuance until the principal 
thereof becomes due and payable, and on any overdue principal and (to the 
extent that payment of such interest is enforceable under applicable law) on 
any overdue installment of interest at the Coupon Rate, payable (subject to 
the provisions of Article Four) [        ] in arrears on [        ] of each 
year (each, an "Interest Payment Date"), commencing on [      ], 199[ ], to 
the person in whose name such Note or any 

                               5



predecessor Note is registered, at the close of business on the regular 
record date for such interest installment, which, in respect of any Notes of 
which the Property Trustee is the registered holder of or a Global Note, 
shall be the close of business on the Business Day next preceding that 
Interest Payment Date. Notwithstanding the foregoing sentence, if (i) the 
Preferred Securities are no longer in book-entry only form or (ii) a 
Dissolution Event has occurred and subsequent thereto the Notes are not 
represented by a Global Note pursuant to the provisions of Section 2.11(c) of 
the Indenture, the Company may select a regular record date for such interest 
installment which shall be any date at least one Business Day before an 
Interest Payment Date.

          (b)  The amount of interest payable for any period will be computed 
on the basis of a 360-day year of twelve 30-day months.  Except as provided 
in the following sentence, the amount of interest payable for any period 
shorter than a full [       ] period for which interest in computed, will be 
computed on the basis of the actual number of days elapsed per 30-day month.  
In the event that any date on which interest is payable on the Notes is not a 
Business Day, then payment of interest payable on such date will be made on 
the next succeeding day which is a Business Day (and without any interest or 
other payment in respect of any such delay), except that, if such Business 
Day is in the next succeeding calendar year, such payment shall be made on 
the immediately preceding Business Day, in each case with the same force and 
effect as if made on such date.

          (c)  If at any time while the Property Trustee is the holder of any 
Notes, the Trust or the Property Trustee is required to pay any taxes, duties 
assessments or governmental changes of whatever nature (other than 
withholding taxes) imposed by the United States, or any other taxing 
authority, then, in any case, the Company will pay as additional interest 
("Additional Interest") on the Notes held by the Property Trustee, such 
additional amounts as shall be required so that the net amounts received and 
retained by the Trust and the Property Trustee after paying such taxes, 
duties assessments or other governmental changes will be equal to the amounts 
the Trust and the Property Trustee would have received had no such taxes, 
duties, assessments or other government changes been imposed.

                                  ARTICLE III

                             REDEMPTION OF THE NOTES

          SECTION 3.1     SPECIAL EVENT REDEMPTION

          If a Special Event has occurred and is continuing then, 
notwithstanding Section 3.2 but subject to Section 3.3(c), the Company shall 
have the right, upon not less than 30 days' nor 

                                     6



more than 60 days' notice to the registered holders of the Notes to redeem 
the Notes in whole or in part for cash within 90 days following the 
occurrence of such Special Event at a redemption price (the "Special Event 
Redemption Price") equal to [   ]% of the principal amount of such Notes to 
be redeemed plus any accrued and unpaid interest thereon to the date of such 
redemption.

          SECTION 3.2     OPTIONAL REDEMPTION BY COMPANY.

          (a)  Subject to the provisions of Section 3.3(c) and to the 
provisions of Article Three of the Indenture, the Company shall have the 
right to redeem the Notes, in whole or in part, from time to time, on or 
after [         ], at a redemption price (the "Optional Redemption Price") 
equal to [      ]% of the principal amount per Note, plus, in each case, 
accrued and unpaid interest thereon to the date of the redemption for the 
Notes.  Any redemption pursuant to this paragraph will be made upon not less 
than 30 days nor more than 60 days notice before the redemption date to each 
Holder of the Notes, at the Redemption Price.  

          SECTION 3.3     REDEMPTION PROCEDURES

          (a)If the Notes are only partially redeemed pursuant to  
Section 3.1 or Section 3.2, the Notes will be redeemed PRO RATA or by lot or 
by any other method utilized by the Trustee; PROVIDED, that if at the time of 
redemption the Notes are registered as Global Notes, the Depositary shall 
determine, in accordance with its procedures, the principal amount of such 
Notes held by each Holder of Notes to be redeemed.

                                  ARTICLE IV

                      EXTENSION OF INTEREST PAYMENT PERIOD

          SECTION 4.1     EXTENSION OF INTEREST PAYMENT PERIOD

          The Company shall have the right, at any time during the term of 
the Notes, from time to time to extend the interest payment period of such 
Notes for up to [  ] consecutive [            ] periods (the "Extended 
Interest Payment Period").  To the extent permitted by applicable law, 
interest, the payment of which has been deferred because of the extension of 
the interest payment period pursuant to this Section 4.1, will bear interest 
thereon at the Coupon Rate for each [            ] period of the Extended 
Interest Payment Period.  At the end of the Extended Interest Payment Period 
the Company shall pay all interest accrued and unpaid on the Notes including 
any Additional Interest ("Deferred Interest") which shall be payable to the 
holders of the Notes in whose names the Notes are registered in the Security 
Register on the first record date after the end of the Extended Interest 
Payment Period.  Before the termination of any Extended Interest Payment 
Period, the Company may further extend such period, PROVIDED that such period 
together with all such further extensions thereof shall not exceed [  ] 
consecutive [          ] periods.  Upon the termination of any Extended 
Interest Payment Period and upon the payment of all Deferred Interest then 
due, the Company may select a new Extended Interest Payment Period, subject 
to the foregoing requirements.  No interest shall be due and payable during 
an Extended Interest Payment Period, except at the end thereof.

          SECTION 4.2     NOTICE OF EXTENSION

          (a)  If the Property Trustee is the only registered holder of the 
Notes at the time the Company selects an Extended Interest Payment Period, 
the Company shall give written notice to both the Regular Trustees and the 
Property Trustee of its selection of such Extended Interest Payment Period 
one Business Day before the earlier of (i) the next succeeding date on which 
Distributions on the Trust Securities issued by the Trust are payable, or 
(ii) the date the Trust is required to give notice of the record date or the 
date such Distributions are payable to the New York Stock Exchange or other 
applicable self-regulatory organization or to holders of the Preferred 
Securities issued by the Trust, but in any event at least one Business Day 
before such record date.

          (b)  If the Property Trustee is not the only holder of the Notes at 
the time the Company selects an Extended Interest Payment Period, the Company 
shall give the holders of the Notes written notice of its selection of such 
Extended Interest Payment Period 10 Business Days before the earlier of (i) 
the next 

                               8



succeeding Interest Payment Date, or (ii) the date the Company is required to 
give notice of the record or payment date of such interest payment to the New 
York Stock Exchange or other applicable self-regulatory organization or to 
holders of the Notes.

          (c)  The [            ] period in which any notice is given 
pursuant to paragraphs (a) or (b) of this Section 4.2 shall be counted as one 
of the [  ] [            ] periods permitted in the maximum Extended Interest 
Payment Period permitted under Section 4.1.

Company to any Person pursuant to Section 5.1.

                                  ARTICLE VI

                                 SUBORDINATION

          SECTION 6.1    AGREEMENT TO SUBORDINATE

          The Company and the Guarantor covenant and agree, and each holder 
of Notes issued hereunder by holder's acceptance thereof likewise covenants 
and agrees, that all Notes shall be issued subject to the provisions of this 
Article Six; and each holder of a Note, whether upon original issue or upon 
transfer or assignment thereof, accepts and agrees to be bound by such 
provisions.

          The payment by the Company of the principal of, premium, if any, 
and interest on all Notes issued hereunder shall, to the extent and in the 
manner hereinafter set forth, be subordinated and junior in right of payment

The payment by the Guarantor of any obligation due under the Note Guarantee 
issued hereunder shall, to the extent and in the manner hereinafter set

date of this Indenture or thereafter incurred.

          No provision of this Article Six shall prevent the occurrence of 
any default or Event of Default hereunder.

          SECTION 6.2    DEFAULT ON SENIOR INDEBTEDNESS

          In the event and during the continuation of any default by the 
Company or the Guarantor in the payment of principal, premium, interest or 
any other payment due on any Senior Indebtedness of the Company or the 
Guarantor, as the case may be, or in the event that the maturity of any 
Senior Indebtedness of the Company or the Guarantor, as the case may be, has 
been accelerated because of a default, then, in either case, no payment shall 
be made by the Company with respect to the principal (including redemption 
and sinking fund payments) of, or premium, if any, or interest on the Notes, 
including payment with respect to any obligation due under the Guarantees.

          In the event that, notwithstanding the foregoing, any payment
shall be received by the Trustee or any holder when such payment is
prohibited by the preceding paragraph of this Section 

                                      11


6.2, such payment shall be held in trust for the benefit of, and shall be 
paid over or delivered to, the holders of Senior Indebtedness or their 
respective representatives, or to the trustee or trustees under any indenture 
pursuant to which any of such Senior Indebtedness may have been issued, as 
their respective interests may appear, but only to the extent that the 
holders of the Senior Indebtedness (or their representative or 
representatives or a trustee) notify the Trustee within 90 days of such 
payment of the amounts then due and owing on the Senior Indebtedness and only 
the amounts specified in such notice to the Trustee shall be paid to the 
holders of Senior Indebtedness.

          SECTION 6.3    LIQUIDATION: DISSOLUTION; BANKRUPTCY

          Upon any payment by the Company or the Guarantor, or distribution

winding-up or liquidation or reorganization of the Company or the Guarantor, 
whether voluntary or involuntary or in bankruptcy, insolvency, receivership 
or other proceedings, all amounts due upon all Senior Indebtedness of the 
Company or the Guarantor, as the case may be, shall first be paid in full, or 
payment thereof provided for in money in accordance with its terms, before 
any payment is made by the Company or the Guarantor, as the case may be, on 
account of the principal (and premium, if any) or interest on the Notes; and 
upon any such dissolution or winding-up or liquidation or reorganization any 
payment by the Company or the Guarantor, or distribution of assets of the 
Company or the Guarantor of any kind or character, whether in cash, property 
or securities, to which the holders of the Note or the Trustee would be 
entitled to receive from the Company or the Guarantor, as the case may be, 
except for the provisions of this Article Six, shall be paid by the Company 
or the Guarantor, as the case may be, or by any receiver, trustee in 
bankruptcy, liquidating trustee, agent or other Person making such payment or 
distribution, or by the holders of the Notes or by the Trustee under this 
Indenture if received by them or it, directly to the holders of Senior 
Indebtedness of the Company or the Guarantor, as the case may be (pro rata to 
such holders on the basis of the respective amounts of Senior Indebtedness 
held by such holders, as calculated by the Company or the Guarantor, as the 
case may be) or their representative or representatives, or to the trustee or 
trustees under any indenture pursuant to which any instruments evidencing 
such Senior Indebtedness may have been issued, as their respective interests 
may appear, to the extent necessary to pay such Senior Indebtedness in full, 
in money or money's worth, after giving effect to any concurrent payment or 
distribution to or for the holders of such Senior Indebtedness, before any 
payment or distribution is made to the holders of Notes or to the Trustee.


                                      12


          In the event that, notwithstanding the foregoing, any payment or 
distribution of assets of the Company or the Guarantor of any kind or 
character, whether in cash, property or securities, prohibited by the 
foregoing, shall be received by the Trustee or the holders of the Notes 
before all Senior Indebtedness of the Company or the Guarantor is paid in 
full, or provision is made for such payment in money in accordance with its 
terms, such payment or distribution shall be held in trust for the benefit of 
and shall be paid over or delivered to the holders such Senior Indebtedness 
or their representative or representatives, or to the trustee or trustees 
under any indenture pursuant to which any instruments evidencing such Senior 
Indebtedness may have been issued, and their respective interests may appear, 
as calculated by the Company or the Guarantor, for application to the payment 
of all Senior Indebtedness of the Company or the Guarantor, as the case may 
be, remaining unpaid to the extent necessary to pay such Senior Indebtedness 
in full in money in accordance with its terms, after giving effect to any 
concurrent payment or distribution to or for the holders of such Senior 
Indebtedness.

          For purposes of this Article Six, the words "cash, property or 
securities" shall not be deemed to include shares of stock of the Company or 
the Guarantor as reorganized or readjusted, or securities of the Company or 
the Guarantor or any other corporation provided for by a plan of 
reorganization or readjustment, the payment of which is subordinated at least 
to the extent provided in this Article Six with respect to the Notes to the 
payment of all Senior Indebtedness of the Company or the Guarantor, as the 
case may be, that may at the time be outstanding, PROVIDED that (i) such 
Senior Indebtedness is assumed by the new corporation, if any, resulting from 
any such reorganization or readjustment, and (ii) the rights of the holders 
of such Senior Indebtedness are not, without the consent of such holders, 
altered by such reorganization or readjustment.  The consolidation of the 
Company or the Guarantor with, or the merger of the Company or the Guarantor 
into, another corporation or the liquidation or dissolution of the Company or 
the Guarantor following the conveyance or transfer of its property as an 
entirety, or substantially as an entirety, to another corporation upon the 
terms and conditions provided for in Article Ten of the Indenture shall not 
be deemed a dissolution, winding-up, liquidation or reorganization for the 
purposes of this Section 6.3 if such other corporation shall, as a part of 
such consolidation, merger, conveyance or transfer, comply with the 
conditions stated in Article Ten of the Indenture.  Nothing in Section 6.2 or 
in this Section 6.3 shall apply to claims of, or payments to, the Trustee 
under or pursuant to Section 7.6 of the Indenture.

          SECTION 6.4    SUBROGATION

          Subject to the payment in full of all Senior Indebtedness of the 
Company or the Guarantor, the rights of the holders of the Notes shall be 
subrogated to the rights of the holders of such Senior Indebtedness to 
receive payments or distributions of cash, property or securities of the 
Company or the Guarantor, as the case may be, applicable to such Senior 
Indebtedness until the principal of (and premium, if any) and interest on the 
Notes shall be paid in full; and, for the purposes of such subrogation, no 
payments or distributions to the holders for such Senior Indebtedness of any 
cash, property or securities to which the holders of the Notes or the Trustee 
would be entitled except for the provisions of this Article Six, and no 
payment over pursuant to the provisions of this Article Six, to or for the 
benefit of the holders of such Senior Indebtedness by holders of the Notes or 
the Trustee, shall, as between (i) the Company, its creditors other than 
holders of Senior Indebtedness of the Company, and the holders of the Notes 
or (ii) the Guarantor, its creditors other than the holders of Senior 
Indebtedness of the Guarantor, and the holders of the Notes, be deemed to be 
a payment by the Company or the Guarantor, as the case may be, to or on 
account of such Senior Indebtedness.  It is understood that the provisions of 
this Article Six are and are intended solely for the purposes of defining the 
relative rights of the holders of the Notes, on the one hand, and the holders 
of such Senior Indebtedness on the other hand.

          Nothing contained in this Article Six or elsewhere in this 
Indenture or in the Notes is intended to or shall impair, as between (i) the 
Company, its creditors other than the holders of Senior Indebtedness of the 
Company, and the holders of the Notes or (ii) the Guarantor, its creditors 
other than the holders of Senior Indebtedness of the Guarantor, and the 
holders of the Notes, the obligation of the Company or the Guarantor, as the 
case may be, which is absolute and unconditional, to pay to the holders of 
the Notes the principal of (and premium, if any) and interest on the Notes as 
and when the same shall become due and payable in accordance with their 
terms, or is intended to or shall affect the relative rights of the holders 
of the Notes and creditors of the Company or the Guarantor, as the case may 
be, other than the holders of Senior Indebtedness of the Company or the 
Guarantor, as the case may be, nor shall anything herein or therein prevent 
the Trustee or the holder of any Note from exercising all remedies otherwise 
permitted by applicable law upon default under the Indenture, subject to the 
rights, if any, under this Article Six of the holders of such Senior 
Indebtedness in respect of cash, property or securities of the Company or the 
Guarantor, as the case may be, received upon the exercise of any such remedy.


                                      14


          Upon any payment or distribution of assets of the Company or the 
Guarantor referred to in this Article Six, the Trustee, subject to the 
provisions of Section 7.1 of the Indenture, and the holders of the Notes, 
shall be entitled to rely upon any order or decree made by any court of 
competent jurisdiction in which such dissolution, winding-up, liquidation or 
reorganization proceedings are pending, or a certificate of the receiver, 
trustee in bankruptcy, liquidation trustee, agent or other Person making such 
payment or distribution, delivered to the Trustee or to the holders of the 
Notes, for the purposes of ascertaining the Persons entitled to participate 
in such distribution, the holders of Senior Indebtedness and other 
indebtedness of the Company or the Guarantor, as the case may be, the amount 
thereof or payable thereon, the amount or amounts paid or distributed thereon 
and all other facts pertinent thereto or to this Article Six.

          SECTION 6.5    TRUSTEE TO EFFECTUATE SUBORDINATION

          Each holder of Notes by such holder's acceptance thereof authorizes 
and directs the Trustee on such holder's behalf to take such action as may be 
necessary or appropriate to effectuate the subordination provided in this 
Article Six and appoints the Trustee such holder's attorney-in-fact for any 
and all such purposes.

          SECTION 6.6    NOTICE BY THE COMPANY AND THE GUARANTOR

          The Company or the Guarantor shall give prompt written notice to a 
Responsible Officer of the Trustee of any fact known to the Company or the 
Guarantor that would prohibit the making of any payment of monies to or by 
the Trustee in respect of the Notes pursuant to the provisions of this 
Article Six.  Notwithstanding the provisions of this Article Six or any other 
provision of the Indenture and this [      ]  Supplemental Indenture, the 
Trustee shall not be charged with knowledge of the existence of any facts 
that would prohibit the making of any payment of monies to or by the Trustee 
in respect of the Notes pursuant to the provisions of this Article Six, 
unless and until a Responsible Officer of the Trustee shall have received 
written notice thereof at the Principal Office of the Trustee from the 
Company or the Guarantor or a holder or holders of Senior Indebtedness or 
from any trustee therefor; and before the receipt of any such written notice, 
the Trustee, subject to the provisions of Section 7.1 of the Indenture, shall 
be entitled in all respects to assume that no such facts exist; PROVIDED, 
HOWEVER, that if the Trustee shall not have received the notice provided for 
in this Section 6.6 at least two Business Days prior to the date upon which 
by the terms hereof any money may become payable for any purpose (including, 
without limitation, the payment of the principal of (or premium, if any) or 
interest on any Note), then, anything herein contained to the contrary 

                                      15


notwithstanding, the Trustee shall have full power and authority to receive 
such money and to apply the same to the purposes for which they were 
received, and shall not be affected by any notice to the contrary that may be 
received by it within two Business Days prior to such date.

          The Trustee, subject to the provisions of Section 7.1 of the 
Indenture, shall be entitled to rely on the delivery to it of a written 
notice by a Person representing himself to be a holder of Senior Indebtedness 
of the Company or the Guarantor, as the case may be (or a trustee on behalf 
of such holder) to establish that such notice has been given by a holder of 
such Senior Indebtedness or a trustee on behalf of any such holder or 
holders.  In the event that the Trustee determines in good faith that further 
evidence is required with respect to the right of any Person as a holder of 
such Senior Indebtedness to participate in any payment or distribution 
pursuant to this Article Six, the Trustee may request such Person to furnish 
evidence to the reasonable satisfaction of the Trustee as to the amount of 
such Senior Indebtedness held by such Person, the extent to which such Person 
is entitled to participate in such payment or distribution and any other 
facts pertinent to the rights of such Person under this Article Six, and if 
such evidence is not furnished the Trustee may defer any payment to such 
Person pending judicial determination as to the right of such Person to 
receive such payment.

          SECTION 6.7    RIGHTS OF THE TRUSTEE; HOLDERS OF SENIOR
                         INDEBTEDNESS

          The Trustee in its individual capacity shall be entitled to all the 
rights set forth in this Article Six, in respect of any Senior Indebtedness 
at any time held by it, to the same extent as any other holder of Senior 
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any 
of its rights as such holder.

          With respect to the holders of Senior Indebtedness of the Company 
or the Guarantor, the Trustee undertakes to perform or to observe only such 
of its covenants and obligations as are specifically set forth in this 
Article Six, and no implied covenants or obligations with respect to the 
holders of such Senior Indebtedness shall be read into this Indenture against 
the Trustee.  The Trustee shall not be deemed to owe any fiduciary duty to 
the holders of such Senior Indebtedness and, subject to the provisions of 
Section 7.1 of the Indenture, the Trustee shall not be liable to any holder 
of such Senior Indebtedness if it shall pay over or deliver to holders of 
Notes, the Company, the Guarantor or any other Person money or assets to 
which any holder of such Senior Indebtedness shall be entitled by virtue of 
this Article Six or otherwise.

                                      16


          SECTION 6.8    SUBORDINATION MAY NOT BE IMPAIRED

          No right of any present or future holder of any Senior Indebtedness 
of the Company or the Guarantor to enforce subordination as herein provided 
shall at any time in any way be prejudiced or impaired by any act or failure 
to act on the part of the Company or the Guarantor, as the case may be, or by 
any act or failure to act, in good faith, by any such holder, or by any 
noncompliance by the Company or the Guarantor, as the case may be, with the 
terms, provisions and covenants of this Indenture, regardless of any 
knowledge thereof that any such holder may have or otherwise be charged with.

          Without in any way limiting the generality of the foregoing 
paragraph, the holders of Senior Indebtedness of the Company or the Guarantor 
may, at any time and from time to time, without the consent of or notice to 
the Trustee or the holders of the Notes, without incurring responsibility to 
the holders of the Notes and without impairing or releasing the subordination 
provided in this Article Six or the obligations hereunder of the holders of 
the Notes to the holders of such Senior Indebtedness, do any one or more of 
the following: (i) change the manner, place or terms of payment or extend the 
time of payment of, or renew or alter, such Senior Indebtedness, or otherwise 
amend or supplement in any manner such Senior Indebtedness or any instrument 
evidencing the same or any agreement under which such Senior Indebtedness is 
outstanding; (ii) sell, exchange, release or otherwise deal with any property 
pledged, mortgaged or otherwise securing such Senior Indebtedness; (iii) 
release any Person liable in any manner for the collection of such Senior 
Indebtedness; and (iv) exercise or refrain from exercising any rights against 
the Company or the Guarantor, as the case may be, and any other Person.

efforts to list such Notes on the New York Stock Exchange or on such other

          The Company, the Guarantor and the Trustee acknowledge that 
pursuant to the Declaration, the holders of Preferred Securities are

"Company", which term includes any successor corporation under the Indenture 
hereinafter referred to), for value received, hereby promises to pay to 
_________ or registered assigns, 

                                      18


the principal sum of Dollars on [      ] and to pay interest on said principal 
sum from [     ], 199[ ] or from the most recent interest payment date (each 
such date, an "Interest Payment Date") to which interest has been paid or duly
provided for, [            ] (subject to deferral as set forth herein) in
arrears on [              ] of each year commencing [            ], 199[  ]
at the rate of [   ]% per annum until the principal hereof shall have
become due and payable, and on any overdue principal and premium, if any,
and (without duplication and to the extent that payment of such interest is
enforceable under applicable law) on any overdue installment of interest at
the same rate per annum.  The amount of interest payable on any Interest
Payment Date shall be computed on the basis of a 360-day year of twelve
30-day months. In the event that any date on which interest is payable on
this Note is not a Business Day, then payment of interest payable on such
date will be made on the next succeeding day which is a Business Day (and
without any interest or other payment in respect of any such delay), except
that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each
case with the same force and effect as if made on such date.  The interest
installment so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in the Indenture, be paid to the
person in whose name this Note (or one or more Predecessor Securities, as
defined in said Indenture) is registered at the close of business on the
regular record date for such interest installment [which shall be the close
of business on the business day next preceding such Interest Payment Date
unless otherwise provided for in the Indenture].  [IF PURSUANT TO THE
PROVISIONS OF SECTION 2.11(C) OF THE INDENTURE THE NOTES ARE NO LONGER
REPRESENTED BY A GLOBAL NOTE -- which shall be the close of business on the
____ business day next preceding such Interest Payment Date.]  Any such
interest  installment not punctually paid or duly provided for shall
forthwith cease to be payable to the registered holders on such regular 
record date, and may be paid to the person in whose name this Note (or one or 
more Predecessor Securities) is registered at the close of business on a 
special record date to be fixed by the Trustee for the payment of such 
defaulted interest, notice whereof shall be given to the registered holders 
of this series of Notes not less than 10 days prior to such special record 
date, or may be paid at any time in any other lawful manner not inconsistent 
with the requirements of any securities exchange on which the Notes may be 
listed, and upon such notice as may be required by such exchange, all as more 
fully provided in the Indenture.  The principal of (and premium, if any) and 
the interest on this Note shall be payable at the office or agency of the 
Trustee maintained for that purpose in any coin or currency of the United 
States of America which at the time of payment is legal tender for payment of 
public and private debts; PROVIDED, HOWEVER, that payment of interest may be 
made at the option of the Company by check mailed to the registered 

                                      19


holder at such address as shall appear in the Security Register.  
Notwithstanding the foregoing, so long as the Holder of this Note is the 
Property Trustee, the payment of the principal of (and premium, if any) and 
interest on this Note will be made at such place and to such account as may 
be designated by the Property Trustee.

          The indebtedness evidenced by this Note is, to the extent provided 
in the Indenture, subordinate and junior in right of payment to the prior 
payment in full of all Senior Indebtedness, and this Note is issued subject 
to the provisions of the Indenture with respect thereto. Each Holder of this 
Note, by accepting the same, (a) agrees to and shall be bound by such 
provisions, (b) authorizes and directs the Trustee on his or her behalf to 
take such action as may be necessary or appropriate to acknowledge or 
effectuate the subordination so provided and (c) appoints the Trustee his or 
her attorney-in-fact for any and all such purposes. Each Holder hereof, by 
his or her acceptance hereof, hereby waives all notice of the acceptance of 
the subordination provisions contained herein and in the Indenture by each 
holder of  Senior Indebtedness, whether now outstanding or hereafter 
incurred, and waives reliance by each such Holder upon said provisions. 

          This Note shall not be entitled to any benefit under the Indenture 
hereinafter referred to, be valid or become obligatory for any purpose until 
the Certificate of Authentication hereon shall have been signed by or on 
behalf of the Trustee.

          The provisions of this Note are continued on the reverse side 
hereof and such continued provisions shall for all purposes have the same 
effect as though fully set forth at this place.


                                      20


          IN WITNESS WHEREOF, the Company has caused this instrument to be 
executed.

                               [FORM OF GUARANTEE]

          FOR VALUE RECEIVED, MediaOne Group, Inc., a Delaware corporation
(the "Guarantor"), hereby unconditionally guarantees to the holder of the
Security upon which this Guarantee is endorsed the due and punctual payment
of the principal of, sinking fund payment, if any, premium, if any, or
interest on said Security, when and as the same shall become due and
payable, whether at maturity, upon redemption or otherwise, according to
the terms thereof and of the Indenture referred to therein.

          The Guarantor agrees to determine, at least one Business Day
prior to the date upon which a payment of principal of, sinking fund
payment, if any, premium, if any, or interest on said Security is due and
payable, whether the Company has available the funds to make such payment
as the same shall become due and payable.  In case of the failure of the
Company punctually to pay any such principal, sinking fund payment, if any,
premium, if any, or interest, the Guarantor hereby agrees to cause any such
payment to be made punctually when and as the same shall become due and
payable, whether at maturity, upon redemption, or otherwise, and as if such
payment were made by the Company.

          The Guarantor hereby agrees that its obligations hereunder shall
be unconditional, irrevocable, and absolute, irrespective of the validity,
regularity, or enforceability of said Security of said Indenture, the
absence of any action to enforce the same, any waiver or consent by the
Holder of said Security with respect to any provisions thereof, the
recovery of any judgment against the Company or any action to enforce the
same, or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a guarantor.  The Guarantor hereby waives
diligence, presentment, demand of payment, filing of claims with a court in
the event of merger or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest or notice with respect to
said Security or indebtedness evidenced thereby, and all demands whatsoever
and covenants that this Guarantee will not be discharged except by complete
performance of the obligations contained in said Security and in this
Guarantee.

          The Guarantor shall be subrogated to all rights of the holder of
said Security against the Company in respect of any amounts paid by the
Guarantor pursuant to the provisions of this Guarantee; provided, however,
that the Guarantor shall not, without the consent of the holders of all of
the Securities then outstanding, be entitled to enforce or to receive any
payments arising out of or based upon such right of subrogation until the
principal of and premium, if any, and interest on all Securities shall have
been paid in full or payment thereof shall have been provided for in
accordance with said Indenture.

                                      22


          Notwithstanding anything to the contrary contained herein, if
following any payment of principal or interest by the Company on the
Securities to the holders of the Securities it is determined by a final
decision of a court of competent jurisdiction that such payment shall be
avoided by a trustee in bankruptcy (including any debtor-in-possession) as
a preference under 11 U.S.C. Section 547 and such payment is paid by such
holder to such trustee in bankruptcy, then and to the extent of such
repayment, the obligations of the Guarantor hereunder shall remain in full
force and effect.

          The obligations of the Guarantor under this Guarantee are, to the
extent provided in the Indenture, subordinate and junior in right of
payment to the prior payment in full of all Senior Indebtedness, and this
Guarantee is issued subject to the provisions of the Indenture with respect
thereto.  Each Holder of the Security upon which this Guarantee is
endorsed, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his or her behalf to
take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination so provided and (c) appoints the Trustee his
or her attorney-in-fact for any and all such purposes.  Each Holder of the
Security upon which this Guarantee is endorsed, by his or her acceptance
thereof, hereby waives all notice of the acceptance of the subordination
provisions contained herein and in the Indenture by each holder of Senior
Indebtedness, whether now outstanding or hereafter incurred, and waives
reliance by each Holder upon said provisions.

          This Guarantee shall not be valid or become obligatory for any
purpose with respect to a Security until the certificate of authentication
on such Security shall have been signed by the Trustee (or the
Authentication Agent).

          This Guarantee shall be governed by the laws of the State of New
York.

          IN WITNESS WHEREOF, MediaOne Group, Inc. has caused this
Guarantee to be executed.

                            (FORM OF REVERSE OF NOTE)

          This Note is one of a duly authorized series of Securities of the
Company (herein sometimes referred to as the "Notes"), specified in the
Indenture, all issued or to be issued in one or more series under and
pursuant to an indenture (the "Base Indenture") dated as of June 12, 1998
among the Company, MediaOne Group, Inc., a Delaware corporation, as
Guarantor (the "Guarantor") and Norwest Bank Minnesota, National
Association, as Trustee (the "Trustee"), as supplemented by the [     ]
Supplemental Indenture dated as of [      ], 199[ ] among the Company, the
Guarantor and the Trustee (the Base Indenture as so supplemented, the
"Indenture"), to which Indenture and all indentures supplemental thereto
reference is hereby made for a description of the rights, limitations of
rights, obligations, duties and immunities thereunder of the Trustee, the
Company and the holders of the Notes.  By the terms of the Indenture, the
Notes are issuable in series which may vary as to amount, date of maturity,
rate of interest and in other respects as in the Indenture provided.  This
series of Notes is limited in aggregate principal amount as specified in
said [      ] Supplemental Indenture.

          Because of the occurrence and continuation of a   Special Event,
the Company shall have the right to redeem this Note at the option of the
Company, without premium or penalty, in whole or in part within 90 days of
the occurrence of such Special Event, at a redemption price (the "Special
Event Redemption Price") equal to [    ]% of the principal amount of this
Note plus any accrued and unpaid interest thereon to the date of such
redemption.

          The Company shall have the right to redeem this Note at the
option of the Company, without premium or penalty, in whole or in part, on
or after [          ] (an "Optional Redemption"), at a redemption price
(the "Optional Redemption Price") equal to [     ]% of the principal amount
per Note, plus, in each case, accrued and unpaid interest thereon to the
date of redemption for the Notes.  

          Any redemption will be made upon not less than 30 days nor more
than 60 days notice before the redemption date, at the Redemption Price. 
If the Notes are only partially redeemed by the Company, the Notes will be
redeemed PRO RATA or by lot or by any other method utilized by the Trustee;
provided that if, at the time of redemption, the Notes are registered as a
Global Note, the Depositary shall determine the principal amount of such
Notes held by each Noteholder to be redeemed in accordance with its
procedures.

          In the event of redemption of this Note in part only, a new Note
or Notes of this series for the unredeemed portion 

                                      24


hereof will be issued in the name of the Holder hereof upon the cancellation 
hereof.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Notes may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the
Indenture.

     The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Notes of each series affected at the time
outstanding, as defined in the Indenture, to execute supplemental
indentures for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of the Indenture or of any
supplemental indenture or of modifying in any manner the rights of the
Holders of the Notes; PROVIDED, HOWEVER, that no such supplemental
indenture shall (i) extend the fixed maturity of any Notes of any series,
or reduce the principal amount thereof, or reduce the rate or extend the
time of payment of interest thereon, or reduce any premium payable upon the
redemption thereof, without the consent of the Holder of each Note so
affected or (ii) reduce the aforesaid percentage of Notes, the Holders of
which are required to consent to any such supplemental indenture, without
the consent of the Holders of each Note then outstanding and affected
thereby.  The Indenture also contains provisions permitting the Holders of
a majority in aggregate principal amount of the Notes of any series at the
time outstanding affected thereby, on behalf of all of the Holders of the
Notes of such series, to waive any past default in the performance of any
of the covenants contained in the Indenture, or established pursuant to the
Indenture with respect to such series, and its consequences, except a
default in the payment of the principal of or premium, if any, or interest
on any of the Notes of such series and except as provided in Section 4.06
of the Base Indenture.  Any such consent or waiver by the registered Holder
of this Note (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such Holder and upon all future Holders and
owners of this Note and of any Note issued in exchange herefor or in place
hereof (whether by registration of transfer or otherwise), irrespective of
whether or not any notation of such consent or waiver is made upon this
Note.

     No reference herein to the Indenture and no provision of this Note 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 Note at the time and place and at the rate and in the
money herein prescribed.

                                      25


     The Company shall have the right at any time during the term of the
Notes from time to time to extend the interest payment period of such Notes
to up to [  ] consecutive [         ] periods (an "Extended Interest
Payment Period"), at the end of which period the Company shall pay all
interest then accrued and unpaid (together with interest thereon at the
rate specified for the Notes to the extent that payment of such interest is
enforceable under applicable law).  Before the termination of any such
Extended Interest Payment Period, the Company may further extend such
Extended Interest Payment Period, PROVIDED that such Extended Interest
Payment Period together with all such further extensions thereof shall not
exceed [  ] consecutive [         ] periods.  At the termination of any
such Extended Interest Payment Period and upon the payment of all accrued
and unpaid interest and any additional amounts then due, the Company may
select a new Extended Interest Payment Period.

     As provided in the Indenture and subject to certain limitations
therein set forth, this Note is transferable by the registered holder
hereof on the Security Register of the Company, upon surrender of this Note
for registration of transfer at the office or agency of the Company in the
borough of Manhattan, the City and State of New York accompanied by a
written instrument or instruments of transfer in form satisfactory to the
Company or the Trustee duly executed by the registered holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Notes of
authorized denominations and for the same aggregate principal amount and
series will be issued to the designated transferee or transferees.  No
service charge will be made for any such transfer, but the Company may
require payment of a sum sufficient to  cover any tax or other governmental
charge payable in relation thereto.

     Prior to due presentment for registration of transfer of this Note,
the Company, the Trustee, any paying agent and any Security Registrar may
deem and treat the registered holder hereof as the absolute owner hereof
(whether or not this Note shall be overdue and notwithstanding any notice
of ownership or writing hereon made by anyone other than the Security
Registrar) for the purpose of receiving payment of or on account of the
principal hereof and premium, if any, and interest due hereon and for all
other purposes, and neither the Company nor the Trustee nor any paying
agent nor any Note Registrar shall be affected by any notice to the
contrary.

     No recourse shall be had for the payment of the principal of or the
interest on this Note, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement 

                                      26


of any assessment or penalty or otherwise, all such liability being, by the 
acceptance hereof and as part of the consideration for the issuance hereof, 
expressly waived and released.

     [The debentures of this series are issuable only in registered form
without coupons in denominations of $[      ] and any integral multiple
thereof.]  [This Global Note is exchangeable for Notes in definitive form
only under certain limited circumstances set forth in the Indenture.  Notes
of this series so issued are issuable only in registered form without
coupons in denominations of $[     ] and any integral multiple thereof.] 
As provided in the Indenture and subject to certain limitations [herein
and] therein set forth, Notes of this series [so issued] are exchangeable
for a like aggregate principal amount of Notes of this series of a
different authorized denomination, as requested by the Holder surrendering
the same.

     All terms used in this Note which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

Such Notes and Note Guarantees endorsed thereon may be delivered to the

 ]  Supplemental Indenture shall supersede the provisions of the Indenture

          In case any one or more of the provisions contained in this [      ]

be invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect any other provisions of
this [      ] Supplemental Indenture or of the Notes, but this [      ]
Supplemental Indenture and the Notes shall be construed as if such invalid
or illegal or unenforceable provision had never been contained herein or
therein.

     SECTION 10.5   COUNTERPARTS

          This [      ] Supplemental Indenture may be executed in any
