Directors or by a supplemental indenture as permitted by Sections 2.01 and 2.07
in conformity with the provisions of this Indenture;

<PAGE>   23

any Securities under this Section if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken by the Company or if the
Trustee in good faith by its board of directors or board of trustees, executive
committee, or a trust committee of directors or trustees or Responsible Officers
shall determine that such action would expose the Trustee to personal liability
to existing Holders.

         SECTION 2.09 The Securities shall be issuable as registered Securities

numbered, lettered or otherwise distinguished in such manner or in accordance
with such plan as the officers of the Company executing the same may determine
with the approval of the Trustee as evidenced by the execution and
authentication thereof.

         Each Security shall be dated the date of authentication and shall bear
interest, if any, from the applicable date and shall be payable on the dates, in
each case, which shall be specified as contemplated by Section 2.07.

         The person in whose name any Security is registered at the close of
business on any record date applicable to a particular series with respect to
any interest payment date for such series shall be entitled to receive the
interest, if any, payable on such interest payment date notwithstanding the
cancellation of such Security upon any transfer or exchange thereof subsequent
to such record date and prior to such interest payment date; provided, however,
that if and to the extent the Company shall default in the payment of the
interest due, if any, on such interest payment date, such defaulted interest
shall be paid to the persons in whose names the Securities are registered at the
close of business on a record date established for such payment by notice by or
on behalf of the Company to the Holders of the Securities mailed by first class
mail not less than fifteen days prior to such record date to their last
addresses as they shall appear upon the Securities register, such record date to
be not less than five days preceding the date of payment of such defaulted
interest. The term "record date" as used with respect to any interest payment
date (except a date for payment of defaulted interest) shall mean the date
specified as such in the terms of the Securities of any particular series, or,
if no such date is so specified, if such interest payment date is the first day
of a calendar month, the fifteenth day of the next preceding calendar month, or,
if such interest payment date is the fifteenth day of a calendar month, the
first day of such calendar month, whether or not such record date is a Business
Day.

Guarantor signing any of the Securities of any particular issue shall cease to
be such officer before such Securities so signed shall have been authenticated
and made available for delivery by the Trustee or by the authenticating agent on
its behalf, or disposed of by the Company, such Securities nevertheless may be
authenticated and delivered or disposed of as though such person had not ceased
to be such officer of the Company or the Guarantor.

         Only such Securities as shall bear thereon either a certificate of
authentication substantially in the form recited in Section 2.03, above, or an
alternate certificate of authentication substantially in the form recited in
Section 2.04, above, duly executed by the Trustee or by the authenticating agent
on its behalf, respectively, shall be entitled to the benefits of this Indenture
and the Guarantees endorsed thereon or be valid or obligatory for any purpose.
Such certificate by the Trustee or by the authenticating agent on its behalf
upon any Security executed by the Company on which a Guarantee is endorsed by
the Guarantor shall be conclusive evidence that the Security so authenticated
has been duly authenticated and delivered hereunder and that the Holder is
entitled to the benefits of this Indenture and such Guarantee.

         Unless the Company shall establish pursuant to Section 2.07 that the
Securities of a series are to be issued in whole or in part in definitive form,
the Company shall execute and the Trustee shall, in accordance with this Section
and the order of the Company with respect to such series, authenticate and
deliver one or more Securities in global form that (i) shall represent and shall
be denominated in an amount equal to the aggregate principal amount of the
Outstanding Securities of such series to be represented by such Security or
Securities in global form, (ii) shall be registered, if a Registered Security,
in the name of the depositary for such Security or Securities in global form or
the nominee of such depositary, (iii) shall be delivered by the Trustee to such
depositary or pursuant to such depositary's instruction and (iv) shall bear the
legend set forth in Section 2.06 and the terms determined by or pursuant to the
Board Resolution or supplemental indenture relating to such series.

         Each depositary designated pursuant to Section 2.07 for a Registered
Security in global form must, at the time of its designation and at all times
while it serves as depositary, be a clearing agency registered under the
Securities Exchange Act of 1934 and any other applicable statute or regulation.
The Trustee shall have no responsibility to determine if the depositary is so
registered. Each depositary shall enter into an agreement with the Trustee
governing the


                                       12
<PAGE>   25

respective duties and rights of such depositary and the Trustee with regard to
Securities issued in global form.


         SECTION 2.11 Any Security of any series may be exchanged for a like
aggregate principal amount of any Security of the same series of other
authorized denominations. Securities of any series to be exchanged shall be
surrendered at the office or agency to be maintained by the Company as provided
in Section 4.02 (or at either of such offices or agencies if more than one), and
the Company shall execute and register and the Trustee or the authenticating
agent on its behalf shall authenticate and make available for delivery in
exchange therefor the Security or Securities of the same series which the Holder
making the exchange shall be entitled to receive.

         The Company shall keep or cause to be kept, at the office or agency to
be maintained by the Company as provided in Section 4.02 (or at least one of
said offices or agencies, if more than one), a register or registers in which,
subject to such reasonable regulations as it may prescribe, the Company shall
register Securities and shall register the transfer of Securities as in this
Article Two provided. Any such register shall be in written form or in any other
form capable of being converted into written form within a reasonable time. At
all reasonable times the information contained in such register or registers
shall be available for inspection by the Trustee. Upon due presentment for
registration of transfer of any Security of any series at such office or agency,
the Company shall execute and register and the Trustee or the authenticating
agent on its behalf shall authenticate and make available for delivery in the
name of the transferee or transferees a new Security or Securities for a like
aggregate principal amount of any such series.

         All Securities presented for registration of transfer or for exchange
or payment shall (if so required by the Company or the Trustee) be duly endorsed
by, or be accompanied by a written instrument or instruments of transfer in form
satisfactory to the Trustee duly executed by, the Holder or his or her attorney
duly authorized in writing.

         The Company may require payment of a sum sufficient to cover any tax or
other govern-mental charge that may be imposed in connection with any exchange
or transfer of Securities. No service charge shall be made for any such
transaction.

         The Company shall not be required (a) to issue, register the transfer
of or exchange any Securities of any series for a period of fifteen days
preceding the first mailing of notice of redemption of Securities of such series
to be redeemed and ending on the date of such mailing, or (b) to register the
transfer of or exchange any Securities selected, called or being called for
redemption as a whole or the portion being redeemed of any such Securities
selected, called or being called for redemption in part.

         All Securities issued upon any transfer or exchange of Securities shall
be valid obligations of the Company, evidencing the same debt, and entitled to
the same benefits under this Indenture, as the Securities surrendered upon such
transfer or exchange.

         Each Security issued in global form authenticated under this Indenture
shall be registered in the name of the depositary designated for such series or
a nominee thereof and delivered to 


                                       13
<PAGE>   26

such depositary or a nominee thereof or custodian therefor, and each such
Security issued in global form shall constitute a single Security for all
purposes of this Indenture.

         Notwithstanding any other provision (other than the provisions set
forth in the eleventh, twelfth and thirteenth paragraphs of this Section) of
this Section, unless and until it is exchanged in whole or in part for
Securities in certificated form in the circumstances described below, a Security
in global form representing all or a portion of the Securities of a series may
not be transferred except as a whole by the depositary for such series to a
nominee of such depositary or by a nominee of such depositary to such depositary
or another nominee of such depositary or by such depositary or any such nominee
to a successor depositary for such series or a nominee of such successor
depositary.

         If at any time the depositary for the Securities of a series notifies
the Company that it is unwilling or unable to continue as depositary for the
Securities of such series or if at any time the depositary for the Securities of
such series shall no longer be eligible under Section 2.10, the Company shall
appoint a successor depositary with respect to the Securities of such series. If
a successor depositary for the Securities of such series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such ineligibility, the Company shall execute, and the Trustee, upon receipt
of a order of the Company for the authentication and delivery of certificated
Securities of such series of like tenor, shall authenticate and deliver
Securities of such series of like tenor in certificated form, in authorized
denominations and in an aggregate principal amount equal to the principal amount
of the Security or Securities of such series of like tenor in global form in
exchange for such Security or Securities in global form.

         The Company may at any time in its sole discretion determine that
Securities of a series issued in global form shall no longer be represented by
such a Security or Securities in global form. In such event the Company shall
execute, and the Trustee, upon receipt of an order of the Company for the
authentication and delivery of certificated Securities of such series of like
tenor, shall authenticate and make available for delivery, Securities of such
series of like tenor in certificated form, in authorized denominations and in an
aggregate principal amount equal to the principal amount of the Security or
Securities of such series of like tenor in global form in exchange for such
Security or Securities in global form.

         If specified by the Company pursuant to Section 2.07 with respect to a
series of Securities, the Depositary for such series may surrender a Security in
global form of such series in exchange in whole or in part for Securities of
such series in certificated form on such terms as are acceptable to the Company
and such Depositary. Thereupon, the Company shall execute, and the Trustee shall
authenticate and deliver, without service charge,

                  (a) to each Person specified by such Depositary a new
         certificated Security or Securities of the same series of like tenor,
         of any authorized denomination as requested by such Person, in
         aggregate principal amount equal to and in exchange for such Person's
         beneficial interest in the Security in global form; and

                  (b) to such Depositary a new Security in global form of like
         tenor in a denomination equal to the difference, if any, between the
         principal amount of the 

                                       14
<PAGE>   27

         surrendered Security in global form and the aggregate principal amount
         of certificated Securities delivered to Holders thereof.

         Upon the exchange of a Security in global form for Securities in
certificated form, such Security in global form shall be canceled by the
Trustee. Securities in certificated form issued in exchange for a Security in
global form pursuant to this Section shall be registered in such names and in
such authorized denominations as the Depositary for such Security in global
form, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee. The Trustee shall make available for
delivery such Securities to the Persons in whose names such Securities are so
registered.


         SECTION 2.12 Pending the preparation of definitive Securities for any
series the Company may execute and register and the Trustee shall authenticate
and make available for delivery temporary Securities for such series (having
executed Guarantees endorsed thereon), which temporary Securities for such
series are printed, lithographed or typewritten. Temporary Securities for any
series may be of any denomination and substantially in the form of the
definitive Securities for such series, but with such omissions, insertions and
variations as may be appropriate for temporary Securities for any series all as
may be determined by the Company. Temporary Securities for any series may
contain such reference to any provisions of this Indenture as may be
appropriate. Every temporary Security shall be executed and registered by the
Company, have endorsed thereon an executed Guarantee of the Guarantor, and be
authenticated by the Trustee or by the authenticating agent on its behalf upon
the same conditions and in substantially the same manner, and with like effect,
as the definitive Securities for such series. In the case of Securities of any
series, such temporary Securities may be in global form, representing all or a
portion of the Outstanding Securities of such series. Except in the case of
temporary Securities in global form, each of which shall be exchanged in
accordance with the provisions thereof, without unreasonable delay the Company
shall execute and register and shall furnish definitive Securities for such
series (having executed Guarantees endorsed thereon) and thereupon temporary
Securities for such series may be surrendered in exchange therefor at the office
or agency to be maintained by the Company as provided in Section 4.02 (or at any
of said offices or agencies, if more than one), and the Trustee or the
authenticating agent on its behalf shall authenticate and make available for
delivery in exchange for such temporary Securities for such series a like
aggregate principal amount of definitive Securities for such series of
authorized denominations having endorsed thereon executed Guarantees of the
Guarantor. Until so exchanged, the temporary Securities for any series shall be
entitled to the same benefits under this Indenture as definitive Securities for
such series.


         SECTION 2.13 In case any temporary or definitive Security shall become
mutilated or be destroyed, lost or stolen, the Company in its discretion may
execute and register, and upon its request the Trustee shall authenticate and
make available for delivery, a new Security of the same series having an
executed Guarantee endorsed thereon, bearing a number not contemporaneously
outstanding, in exchange and substitution for the Security so mutilated, or in
lieu of and substitution for the Security so destroyed, lost or stolen. In every
case the applicant for a substituted Security of the same series shall furnish
to the Company, to the 


                                       15
<PAGE>   28

Guarantor and to the Trustee such security or indemnity as may be required by
them to save each of them harmless, and, in every case of destruction, loss or
theft, the applicant shall also furnish to the Company, to the Guarantor and to
the Trustee evidence to their satisfaction of the destruction, loss or theft of
such Security and of the ownership thereof. The Trustee may authenticate any
such substituted Security of the same series and make available for delivery the
same upon the written request or authorization of any officer of the Company.
Upon the issuance of any substituted Security, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses connected therewith.
In case any Security which has matured or is about to mature shall become
mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a
substitute Security of the same series, pay or authorize the payment of such
Security (without surrender thereof except in the case of a mutilated Security)
if the applicant for such payment shall furnish to the Company, to the Guarantor
and to the Trustee such security or indemnity as may be required by them to save
each of them harmless and, in case of destruction, loss or theft, evidence to
the satisfaction of the Company, the Guarantor and the Trustee of the
destruction, loss or theft of such Security and of the ownership thereof.

         Every substituted Security of any series issued pursuant to the
provisions of this Section 2.13 by virtue of the fact that any such Security is
destroyed, lost or stolen shall, with respect to such Security, constitute an
additional contractual obligation of the Company guaranteed by the Guarantor as
herein provided, whether or not the destroyed, lost or stolen Security shall at
any time be enforceable by anyone, and shall be entitled to all the benefits of
this Indenture equally and proportionately with any and all other Securities of
the same series duly issued under this Indenture. All Securities shall be held
and owned upon the express condition that (to the extent lawful) the foregoing
provisions shall be exclusive with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities and shall preclude any and all
other rights or remedies, notwithstanding any law or statute now existing or
hereafter enacted to the contrary with respect to the replacement or payment of
negotiable instruments or other securities without their surrender.

         SECTION 2.14 All Securities surrendered for payment, exchange or
registration of transfer shall, if surrendered to the Company, the
authenticating agent or any paying agent, be cancelled and delivered to the
Trustee or, if surrendered to the Trustee, be cancelled by it, and no Securities
shall be issued in lieu thereof except as expressly permitted by any of the
provisions of this Indenture. On written request of the Company, the Trustee
shall deliver to the Company cancelled Securities held by the Trustee. With the
consent of the Company, the Trustee may but shall not be required to destroy
cancelled Securities. If the Company shall acquire any of the Securities,
however, such acquisition shall not operate as a redemption or satisfaction of
the indebtedness represented by such Securities unless and until the same are
cancelled and delivered to the Trustee or surrendered to the Trustee for
cancellation.

         SECTION 2.15 Nothing in this Indenture, the Guarantees or in any
Security of any series, expressed or implied, shall give or be construed to give
to any person other than the parties hereto and their successors and the Holders
of the Securities any legal or equitable right, remedy or claim under or in
respect of this Indenture, or under any covenant, condition or 


                                       16
<PAGE>   29

provision herein contained, all the covenants, conditions and provisions hereof
being for the sole benefit of the parties hereto and their successors and of the
Holders of the Securities.

         SECTION 2.16 The Guarantor hereby guarantees to each Holder of a
Security of any series authenticated by the Trustee and delivered by or on
behalf of the Company the payment of the principal of (and premium, if any) and
interest, if any, on such Security, in accordance with the terms of such
Security and of this Indenture. In the event of any assignment of such Security,
the Guarantor shall have all defenses against the assignee which the Company or
the Guarantor may have against the assignor or any prior assignors. The
Guarantor hereby covenants that this Guarantee will not be discharged as to any
such Security except by payment in full of the principal of (and premium, if
any) and interest thereon.

         The Guarantor shall be subrogated to all rights of the Holder of any
Security against the Company in respect of any amounts paid by the Guarantor
pursuant to the provisions of the Guarantee endorsed thereon; provided, however,
that the Guarantor shall not 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 held by others shall have
been paid in full.

         The provisions of this Section 2.16 are subject to the provisions of
Article Fourteen, whereby the obligations of the Guarantor hereunder and under
the Guarantees are subordinated to the prior payment in full of all Senior
Indebtedness of the Guarantor.

         The Guarantee set forth in this Section 2.16 shall not be valid or
become obligatory for any purpose with respect to a Security of any series until
the certificate of authentication on such Security shall have been manually
executed by the Trustee.

        SECTION 2.17 The Company in issuing the Securities of any series may use
"CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use
"CUSIP" numbers in notices of redemption as a convenience to Holders; provided
that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities of the same
series or as contained in any notice of a redemption and that reliance may be
placed only on the other identification numbers printed on such Securities, and
any such redemption shall not be affected by any defect in or omission of such
numbers. The Company will promptly notify the Trustee of any change in the
"CUSIP" numbers.



                                  ARTICLE THREE

                            REDEMPTION OF SECURITIES

         SECTION 3.01 The provisions of this Article Three shall be applicable
to the Securities of any series which are redeemable before their maturity or to
any sinking fund for the retirement of Securities of a series except as
otherwise specified as contemplated by Section 2.05 for Securities of such
series.

                                       17
<PAGE>   30

         SECTION 3.02 In case the Company shall desire to exercise any right to
redeem all or any part of Securities of any series, as the case may be, in
accordance with the right reserved so to do, it shall fix a date for redemption
and shall give notice of such redemption to the Holders of the Securities of
such series to be redeemed as a whole or in part by mailing a notice of such
redemption by first class mail not less than thirty nor more than sixty days
prior to the date fixed for redemption to their last addresses as they shall
appear upon the Securities register. Any notice which is mailed in the manner
herein provided shall be conclusively presumed to have been duly given, whether
or not the Holder receives the notice. In any case, failure duly to give notice
by mail, or any defect in the notice, to the Holder of any Security of a series
designated for redemption as a whole or in part shall not affect the validity of
the proceedings for the redemption of any other Security of the same series.

         Each such notice of redemption shall identify the Securities to be
redeemed (including the CUSIP number), shall specify the date fixed for
redemption and the redemption price at which Securities of such series are to be
redeemed and shall state that payment of the redemption price of the Securities
of such series or portions thereof to be redeemed will be made at the office or
agency to be maintained by the Company as provided in Section 4.02 (or any of
said offices or agencies, if more than one) upon presentation and surrender of
such Securities, that interest accrued to the date fixed for redemption will be
paid as specified in said notice, and that on and after said date interest
thereon or on the portions thereof to be redeemed will cease to accrue. If less
than all the Securities of any series are to be redeemed, each notice of
redemption shall identify which of such Securities are to be redeemed. In case
any Security is to be redeemed in part only, the notice shall state the portion
of the principal amount thereof to be redeemed and shall state that on and after
the date fixed for redemption, upon presentation and surrender of such Security,
a new Security or Securities of such series in principal amount equal to the
unredeemed portion thereof will be issued.

         If any Securities are to be redeemed, the Company shall give the
Trustee forty-five (45) days' written notice (or such lesser period of time as
approved by the Trustee) in advance as to the aggregate principal amount of such
Securities to be redeemed, and if less than all the Securities of any one series
are to be redeemed, thereupon the Trustee shall select, in such manner as in its
sole discretion it shall deem appropriate and fair, the Securities or portions
thereof to be redeemed and shall thereafter promptly notify the Company in
writing which of the Securities of such series or portions thereof are to be
redeemed. If less than all the Securities of any series with differing issue
dates, interest rates or stated maturities are to be redeemed, the Company, in
its sole discretion, shall select the particular Securities to be redeemed and
shall notify the Trustee in writing thereof at least forty-five (45) days prior
to the relevant redemption date.

         SECTION 3.03 If the giving of notice of redemption shall have been
completed as above provided, the Securities or portions of such Securities
identified in such notice shall become due and payable on the date and at the
place or places stated in such notice at the applicable redemption price,
together with interest accrued to the date fixed for redemption, and unless the
Company shall default in the payment of such Securities, at the redemption
price, together with interest accrued to said date, interest on the Securities
or portions of Securities so


                                       18
<PAGE>   31

called for redemption shall cease to accrue on and after said date. On
presentation and surrender of such Securities at said place or places of payment
in said notice specified, such Securities or portions thereof to be redeemed
shall be paid and redeemed by the Company at the applicable redemption price,
together with interest accrued thereon to the date fixed for redemption.

         Upon presentation and surrender of any Security of a series which is
redeemed in part only, the Company shall execute and register and the Trustee or
the authenticating agent on its behalf shall authenticate and make available for
delivery, at the expense of the Company, a new Security or Securities of the
same series, of authorized denominations, in principal amount equal to the
unredeemed portion of the Security so presented.

         SECTION 3.04 The minimum amount of any sinking fund payment provided
for by the terms of Securities of any series is herein referred to as a
"mandatory sinking fund payment", and any payment in excess of such minimum
amount provided for by the terms of Securities of any series is herein referred
to as an "optional sinking fund payment". The date on which a sinking fund
payment is to be made is herein referred to as the "sinking fund payment date".

         In lieu of making all or any part of any mandatory sinking fund payment
with respect to any series of Securities in cash, the Company may, at its
option, (a) deliver to the Trustee Securities of such series theretofore
purchased or otherwise acquired (except upon redemption pursuant to the
mandatory sinking fund) by the Company or receive credit for Securities of such
series (not previously so credited) theretofore purchased or otherwise acquired
(except as aforesaid) by the Company and delivered to the Trustee for
cancellation pursuant to Section 2.14, (b) receive credit for optional sinking
fund payments (not previously so credited) made pursuant to this Section 3.04,
or (c) receive credit for Securities of such series (not previously so credited)
redeemed by the Issuer through any optional redemption provision contained in
the terms of such series. Securities so delivered or credited shall be received
or credited by the Trustee at the sinking fund redemption price specified in
such Securities.

         On or before the sixtieth day next preceding each sinking fund payment
date for any series, the Company will deliver to the Trustee a written statement
(which need not contain the statements required by Section 15.05) signed by an
authorized officer of the Company (a) specifying the portion of the mandatory
sinking fund payment to be satisfied by payment of cash and the portion to be
satisfied by credit of Securities of such series, (b) stating that none of the
Securities of such series has theretofore been so credited, (c) stating that no
defaults in the payment of interest or Events of Default with respect to such
series have occurred (which have not been waived or cured) and are continuing
and (d) stating whether or not the Company intends to exercise its right to make
an optional sinking fund payment with respect to such series and, if so,
specifying the amount of such optional sinking fund payment which the Company
intends to pay on or before the next succeeding sinking fund payment date. Any
Securities of such series to be credited and required to be delivered to the
Trustee in order for the Company to be entitled to credit therefore as aforesaid
which have not theretofore been delivered to the Trustee shall be delivered for
cancellation pursuant to Section 2.14 to the Trustee with such written statement
(or as reasonably promptly thereafter is acceptable to the Trustee). Such
written statement shall be irrevocable and upon its receipt by the Trustee the
Company shall become unconditionally 


                                       19
<PAGE>   32

obligated to make all the cash payments or payments therein referred to, if any,
on or before the next succeeding sinking fund payment date. Failure of the
Company, on or before any such sixtieth day, to deliver such written statement
and Securities specified in this paragraph, if any, shall not constitute a
default but shall constitute, on and as of such date, the irrevocable election
of the Company (i) that the mandatory sinking fund payment for such series due
on the next succeeding sinking fund payment date shall be paid entirely in cash
without the option to deliver or credit Securities of such series in respect
thereof and (ii) that the Company will make no optional sinking fund payment
with respect to such series as provided in this Section 3.04.

         If the sinking fund payment or payments (mandatory or optional or both)
to be made in cash on the next succeeding sinking fund payment date plus any
unused balance of any preceding sinking fund payments made in cash shall exceed
$50,000 (or a lesser sum if the Company shall so request) with respect to the
Securities of any particular series, such cash shall be applied on the next
succeeding sinking fund payment date to the redemption of Securities of such
series at the sinking fund redemption price together with accrued interest to
the date fixed for redemption. If such amount shall be $50,000 or less and the
Company makes no such request then it shall be carried over until a sum in
excess of $50,000 is available. The Trustee shall select, in the manner provided
in Section 3.02, for redemption on such sinking fund payment date a sufficient
principal amount of Securities of such series to absorb said cash, as nearly as
may be, and shall (if requested in writing by the Company) inform the Company of
the serial numbers of the Securities of such series (or portions thereof) so
selected. Securities of any series which are (a) owned by the Company or an
entity known by the Trustee to be directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company, as
shown by the Security Register, and not known to the Trustee to have been
pledged or hypothecated by the Company or any such entity or (b) identified in
an Officer's Certificate at least 60 days prior to the sinking fund payment date
as being beneficially owned by, and not pledged or hypothecated by, the Company
or an entity directly or indirectly controlling or controlled by or under direct
or indirect common control with the Company shall be excluded from Securities of
such series eligible for selection for redemption. The Trustee, in the name and
at the expense of the Company (or the Company, if it shall so request the
Trustee in writing) shall cause notice of redemption of the Securities of such
series to be given in substantially the manner provided in Section 3.02 (and
with the effect provided in Section 3.03) for the redemption of Securities of
such series in part at the option of the Company. The amount of any sinking fund
payments not so applied or allocated to the redemption of Securities of such
series shall be added to the next cash sinking fund payment for such series and,
together with such payment, shall be applied in accordance with the provisions
of this Section 3.04. Any and all sinking fund moneys held on the stated
maturity date of the Securities of any particular series (or earlier, if such
maturity is accelerated), which are not held for the payment or redemption of
particular Securities of such series shall be applied, together with other
moneys, if necessary, sufficient for the purpose, to the payment of the
principal of, and interest on, the Securities of such series at maturity.

         At least one Business Day before each sinking fund payment date, the
Company shall pay to the Trustee in cash or shall otherwise provide for the
payment of all interest accrued to the date fixed for redemption on Securities
to be redeemed on the next following sinking fund payment date.

                                       20
<PAGE>   33

         The Trustee shall not redeem or cause to be redeemed any Securities of
a series with sinking fund moneys or mail any notice of redemption of Securities
for such series by operation of the sinking fund during the continuance of a
default in payment of interest on such Securities or of any Event of Default
except that, where the mailing of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall redeem or cause to be redeemed
such Securities, provided that it shall have received from the Company a sum
sufficient for such redemption. Except as aforesaid, any moneys in the sinking
fund for such series at the time when any such default or Event of Default shall
occur, and any moneys thereafter paid into the sinking fund, shall, during the
continuance of such default or Event of Default, be deemed to have been
collected under Article Six and held for the payment of all such Securities. In
case such Event of Default shall have been waived as provided in Section 6.06 or
the default cured on or before the sixtieth day preceding the sinking fund
payment date in any year, such moneys shall thereafter be applied on the next
succeeding sinking fund payment date in accordance with this Section 3.04 to the
redemption of such Securities.



                                  ARTICLE FOUR

                       PARTICULAR COVENANTS OF THE COMPANY

         SECTION 4.01 The Company will duly and punctually pay or cause to be
paid the principal of (and premium, if any) and interest on each of the
Securities of any series, at the place or places, at the respective times and in
the manner provided in the Securities of such series and in this Indenture.

         SECTION 4.02 As long as any of the Securities of any series remain
outstanding, the Company will maintain an office or agency in the Borough of
Manhattan, The City of New York, State of New York (and at such other place, if
any, as shall be specified in the form of such Security as a place for payment
of principal and interest) where the Securities may be presented for
registration of transfer and for exchange as in this Indenture provided, where
notices and demands to or upon the Company in respect of the Securities or of
this Indenture may be served and where the Securities may be presented for
payment. The Company will give to the Trustee notice of the location of each
such office or agency and of any change in the location thereof. In case the
Company shall fail to maintain any such office or agency or shall fail to give
such notice of the location or of any change in the location thereof,
presentations may be made and notices and demands may be served at the principal
corporate trust office of the Trustee.

         SECTION 4.03 If the Company shall at any time mortgage, pledge or
otherwise subject to any lien the whole or any part of any property or assets
now owned or hereafter acquired by it, except as hereinafter provided in this
Section 4.03, the Company will secure the outstanding Securities, and any other
obligations of the Company which may then be outstanding and entitled to the
benefit of a covenant similar in effect to this covenant, equally and ratably
with the indebtedness or obligations secured by such mortgage, pledge or lien,
so long as any such indebtedness or obligations shall be so secured. The
foregoing covenant shall not apply to (1) the creation of purchase money
mortgages or liens, including any capital lease obligations, or 


                                       21
<PAGE>   34

to the extension, renewal or refunding thereof, (2) liens on property existing
at the time such property is acquired by the Company, or to the extension,
renewal or refunding thereof, or (3) to the making of any deposit or pledge to
secure public statutory obligations or with any governmental agency at any time
required by law in order to qualify the Company to conduct its business or any
part thereof or in order to entitle it to maintain self insurance or to obtain
benefits of any law relating to worker's compensation, unemployment insurance,
old age pensions or other social security, or with any court, board, commission,
or governmental agency as security incident to the proper conduct of any
proceeding before such court, board, commission or governmental agency. Nothing
herein contained shall prevent a subsidiary or other affiliate of the Company
from mortgaging, pledging or subjecting to any lien any property or assets
whether or not acquired by such subsidiary or affiliate from the Company.

         SECTION 4.04 The Company, whenever necessary to avoid or fill a vacancy
in the office of Trustee, will appoint, in the manner provided in Section 7.10,
a Trustee, so that there shall at all times be a Trustee hereunder.

         SECTION 4.05 (a) Whenever the Company shall appoint a paying agent
other than the Trustee, it will cause such paying agent to execute and deliver
to the Trustee an instrument in which such agent shall agree with the Trustee,
subject to the provisions of this Section 4.05,

                   (1) that it will hold all sums held by it as such agent for
         the payment of the principal of (and premium, if any) or interest on
         the Securities of any series (whether such sums have been paid to it by
         the Company or by any other obligor on the Securities of such series,
         including the Guarantor) in trust for the benefit of the respective
         Holders of the Securities of such series entitled thereto and will
         notify the Trustee of the receipt of sums to be so held,

                   (2) that it will give the Trustee notice of any failure by
         the Company (or by any other obligor on the Securities of such series,
         including the Guarantor) to make any payment of the principal of (or
         premium, if any) or interest on the Securities when the same shall be
         due and payable, and

                  (3) at any time during the continuance of such failure,
         immediately pay to the Trustee all sums so held in trust by the paying
         agent.

          (b) If the Company shall act as its own paying agent, it will, on or
before each due date of the principal of (and premium, if any) or interest on
the Securities of any series, set aside, segregate and hold in trust for the
benefit of the respective holders of the Securities of such series entitled
thereto a sum sufficient to pay such principal (and premium, if any) or interest
if any, so becoming due. The Company will promptly notify the Trustee of any
failure to take such action.

         (c) Anything in this Section 4.05 to the contrary notwithstanding, the
Company may, at any time, for the purpose of obtaining a satisfaction and
discharge of this Indenture pursuant to Section 11.01 or for any other reason,
pay or cause to be paid to the Trustee all sums held in trust by it or any
paying agent hereunder as required by this Section 4.05, such sums to be held by
the Trustee upon the trusts herein contained.

                                       22
<PAGE>   35

         (d) Anything in this Section 4.05 to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section 4.05 is subject to
the provisions of Sections 11.03 and 11.04.


                                  ARTICLE FIVE

                    SECURITYHOLDERS' LISTS AND REPORTS BY THE
                             COMPANY AND THE TRUSTEE

         SECTION 5.01 The Company and Guarantor each covenant and agree that it
will furnish or cause to be furnished to the Trustee a list in such form as the
Trustee may reasonably require of the names and addresses of the Holders of
Securities:

                  (a) semiannually, not more than fifteen days after each record
         date for the payment of semiannual interest on the Securities of such
         series, as specified in the form of such Security, as of such record
         date, and

                  (b) at such other times as the Trustee may request in writing,
         within thirty days after receipt by the Company or the Guarantor of any
         such request, as of a date not more than fifteen days prior to the time
         such information is furnished,

excluding from any such list names and addresses received by the Trustee in the
capacity of Securities registrar, if so acting.

         SECTION 5.02 The Company and the Guarantor each agree to provide
information relating to the Holders of the Securities to the Trustee pursuant to
the requirements of Section 312 of the Trust Indenture Act. The Trustee agrees
to furnish information to the Holders of Securities pursuant to the requirements
of Section 312 of the Trust Indenture Act.

         SECTION 5.03 The Company and the Guarantor each covenant:

         (a) to file with the Trustee, within fifteen days after the Company or
the Guarantor is required to file the same with the Securities and Exchange
Commission, copies of the annual reports and of the information, documents and
other reports (or copies of such portions of any of the foregoing as said
Commission may from time to time by rules and regulations prescribe) which the
Company or the Guarantor may be required to file with said Commission pursuant
to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as
amended; or, if the Company or the Guarantor is not required to file
information, documents or reports pursuant to either of such sections, then to
file with the Trustee and said Commission, in accordance with rules and
regulations prescribed from time to time by said Commission, such of the
supplementary and periodic information, documents and reports which may be
required pursuant to Section 13 of the Securities Exchange Act of 1934, as
amended, in respect of a security listed and registered on a national securities
exchange as may be prescribed from time to time in such rules and regulations,
PROVIDED, HOWEVER, that the Company will not be required to file such 


                                       23
<PAGE>   36

reports with the Commission if (1) the Company has received a No-Action letter
from the Commission stating that the Company is exempt from such filing
requirement due to its reporting on a consolidated basis with the Guarantor, and
(2) the Company continues to report on a consolidated basis with the Guarantor;

          (b) to file with the Trustee and the Securities and Exchange
Commission, in accordance with the rules and regulations prescribed from time to
time by said Commission, such additional information, documents, and reports
with respect to compliance by the Company or the Guarantor, as the case may be,
with the conditions and covenants provided for in this Indenture as may be
required from time to time by such rules and regulations;

         (c) to transmit by mail to all Holders of Securities, as the names and
addresses of such holders appear on the Securities register, within thirty days
after the filing thereof with the Trustee, such summaries of any information,
documents and reports required to be filed by the Company or the Guarantor, as
the case may be, pursuant to subsections (a) and (b) of this Section 5.03 as may
be required by rules and regulations prescribed from time to time by the
Securities and Exchange Commission; delivery of such reports, information and
documents to the Trustee is for informational purposes only and the Trustee's
receipt of such shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including
the Company's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates); and

         (d) to deliver to the Trustee, within 120 days after the end of each
fiscal year of the Company (beginning with respect to Securities of any series
with the fiscal year next following the issue date of such series of
Securities), commencing April 30, 1999, a certificate from its principal
executive officer, principal financial officer or principal accounting officer,
stating whether to the best knowledge of the signer thereof, the Company or the
Guarantor, as the case may be, is in compliance (without regard to periods of
grace or notice requirements) with all conditions and covenants under this
Indenture, and if the Company or the Guarantor, as the case may be, shall not be
in compliance, specifying such non-compliance and the nature and status thereof
of which such signer may have knowledge. For purposes of this Section 5.03(d),
such compliance shall be determined without regard to any period of grace or
requirement of notice provided under this Indenture.

         (e) to deliver to the Trustee, as soon as possible and in any event
within five days after the Company becomes or the Guarantor becomes aware of the
occurrence of any Event of Default or an event which, with notice of the lapse
of time or both, would constitute an Event of Default, an Officers' Certificate
setting forth the details of such Event of Default or default and the action
which the Company or the Guarantor proposes to take with respect thereto.

         SECTION 5.04 (a) The Trustee shall transmit to Holders such reports
concerning the Trustee and its actions under this Indenture as may be required
pursuant to the Trust Indenture Act of 1939 at the times and in the manner
provided pursuant thereto. If required by Section 313(a) of the Trust Indenture
Act of 1939, the Trustee shall, within sixty days after each May 15, comply with

                                       24
<PAGE>   37

         (b) A copy of each such report shall, at the time of such transmission
to Holders, be filed by the Trustee with each stock exchange, if any, upon which
the Securities are listed, with the Commission and with the Company. The Company
will promptly notify the Trustee when the Securities are listed on any stock
exchange and of any delisting thereof.



                                   ARTICLE SIX

                   REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS
                               ON EVENT OF DEFAULT

         SECTION 6.01 In case one or more of the following Events of Default
shall have occurred and be continuing, that is to say:

         (a) default in the payment of any installment of interest upon any of
the Securities of such series as and when the same shall become due and payable,
and continuance of such default for a period of thirty days; or

          (b) default in the payment of the principal of (or premium, if any,
on) any of the Securities as and when the same shall become due and payable
either at maturity, by declaration of acceleration or otherwise; or

         (c) failure on the part of the Company or the Guarantor duly to observe
or perform any other of the covenants or agreements on the part of the Company
or the Guarantor in the Securities of any one series or in this Indenture
contained for a period of sixty days after the date on which written notice of
such failure, requiring the Company or the Guarantor to remedy the same, shall
have been given to the Company or the Guarantor by the Trustee or to the
Company, the Guarantor and the Trustee by the Holders of at least twenty-five
percent in aggregate principal amount of the Securities of such series at the
time outstanding; or

         (d) default in the payment of any sinking fund installment as and when
the same shall become due and payable by the terms of the Securities of such
series; or

         (e) default by the Company or the Guarantor in the payment of the
principal of, interest on, or other amounts payable in respect of, or failure by
the Company or the Guarantor to perform or comply with any of its other
agreements in respect of any of, its Indebtedness (other than the Securities) in
the aggregate principal or like amount of $20 million or more, which default or
failure permits the holder thereof to declare such Indebtedness immediately due
and payable; provided, however, that if such default or failure in respect of
any such Indebtedness shall be cured by the Company or the Guarantor, as the
case may be, as may be permitted by the terms of such Indebtedness, then the
Event of Default hereunder by reason of such default or failure shall be deemed
likewise to have been cured or waived; or

         (f) a court having jurisdiction shall enter a decree or order for
relief in respect to the Company or the Guarantor, as the case may be, in an
involuntary case under any applicable 


                                       25
<PAGE>   38

bankruptcy, insolvency or other similar law now or hereafter in effect, or
appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator
(or similar official) of the Company or the Guarantor or of the property of
either, or ordering the winding-up or liquidation of its affairs and such decree
or order shall remain unstayed and in effect for a period of 60 consecutive
days; or

         (g) the Company or the Guarantor shall commence a voluntary case under
any applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or shall consent to the entry of an order for relief in an involuntary
case under any such law, or shall consent to the appointment of or taking
possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator
(or similar official) of the Company or the Guarantor or of its property, or
shall make any general assignment for the benefit of creditors, or shall fail
generally to pay its debts as they become due or shall take any corporate action
in furtherance of any of the foregoing; or

         (h) any other Event of Default provided in the supplemental indenture
or resolution of the Board of Directors of the Company under which such series
of Securities is issued or in the form of Security for such series;

then and in each and every such case, unless the principal of all the series of
Securities then outstanding shall have already become due and payable, either
the Trustee or the Holders of not less than twenty-five percent in aggregate
principal amount of the Securities of such series then outstanding hereunder, by
notice in writing to the Company and the Guarantor (and to the Trustee if given
by Securityholders), shall declare the principal of all Securities of such
series to be due and payable immediately, and upon any such declaration the same
shall become and shall be immediately due and payable, anything in this
Indenture or in the Securities of such series contained to the contrary
notwithstanding, provided, however, that if an Event of Default specified in
Section 6.01(f) or (g) occurs, all unpaid principal of, premium, if any, and
accrued interest on all outstanding Securities shall, ipso facto, become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder. This provision, however, is subject to the condition
that if, at any time after the principal of the Securities of such series shall
have been so declared due and payable, and before any judgment or decree for the
payment of the moneys due shall have been obtained or entered as hereinafter
provided, the Company or the Guarantor shall pay, or shall deposit with the
Trustee a sum sufficient to pay, all matured installments of interest, if any,
upon all the Securities of such series and the principal of (and premium, if
any, on) any and all Securities of such series which shall have become due
otherwise than by declaration, with interest upon such principal (and premium,
if any) and (to the extent that payment of such interest is enforceable under
applicable law) upon any overdue installments of interest at the same rate as
the rate of interest specified in the Securities of such series (or at the
respective rates of interest or Yields to Maturity of all the Securities, as the
case may be), to the date of such payment or deposit, and such amount as shall
be sufficient to cover reasonable compensation to the Trustee, its agents and
counsel, and all other expenses and liabilities incurred, and all advances made,
by the Trustee, its agents and counsel except as a result of its negligence or
bad faith, and if any and all defaults under this Indenture, other than the
nonpayment of the principal of Securities which have become due by acceleration,
shall have been remedied - then and in every such case the Holders of a majority
in aggregate principal amount of the Securities of such series, each series
voting as a separate class, then outstanding by written notice to the Company,
the Guarantor and to the Trustee may waive 


                                       26
<PAGE>   39

all defaults with respect to such series and rescind and annul such declaration
and its consequences; but no such waiver or rescission or annulment shall extend
to or shall affect any subsequent default or shall impair any right consequent
thereon.


         In case the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
because of such waiver or rescission or annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every such case
the Company, the Guarantor, the Trustee and the Holders of the Securities shall
be restored respectively to their former positions and rights hereunder, and all
rights, remedies and powers of the Company, the Guarantor, the Trustee and the
Holders of the Securities shall continue as though no such proceedings had been
taken.

         SECTION 6.02 The Company covenants that (1) in case default shall be
made in the payment of any installment of interest on any of the Securities of
any issue, as and when the same shall become due and payable, and such default
shall have continued for a period of thirty days, or (2) in case default shall
be made in the payment of the principal of (or premium, if any, on) any of the
Securities of any series when the same shall have become due and payable,
whether upon maturity or upon declaration or otherwise - then, upon demand of
the Trustee, the Company will pay to the Trustee, for the benefit of the Holders
of the Securities of such series, the whole amount that then shall have become
due and payable on all such Securities for principal (and premium, if any) and
interest, as the case may be, with interest upon any overdue principal (and
premium, if any) and (to the extent that payment of such interest is enforceable
under applicable law) upon any overdue installments of interest at the same rate
as the rate of interest specified in the Securities of such series, and, in
addition thereto, such further amount as shall be sufficient to cover reasonable
compensation to the Trustee, its agents and counsel, and all other expenses and
liabilities incurred, and all advances made, by the Trustee, its agents and
counsel except as a result of its negligence or bad faith.

         Until such demand is made by the Trustee, the Company may pay the
principal of and interest on the Securities of any series to the registered
Holders, whether or not the principal of and interest on the Securities of such
series is overdue.

         In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any action or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceedings to judgment or final decree and may enforce any such
judgment or final decree against the Company or other obligor upon the
Securities of any series and against the Guarantor and collect in the manner
provided by law out of the property of the Company, the Guarantor or other
obligor upon the Securities of such series wherever situated the moneys adjudged
or decreed to be payable.

         In case there shall be pending proceedings for the bankruptcy or for
the reorganization of the Company, the Guarantor or any other obligor upon the
Securities of any series under Title 11 of the United States Code or any other
applicable law, or in case a receiver or trustee shall have been appointed for
the property of the Company, the Guarantor or such other obligor, or in case


                                       27
<PAGE>   40

of any other judicial proceedings relative to the Company, the Guarantor or
other obligor upon the Securities of any series, or to the creditors or property
of the Company, the Guarantor or such other obligor, the Trustee, irrespective
of whether the principal of the Securities shall then be due and payable as
therein expressed or by declaration or otherwise and irrespective of whether the
Trustee shall have made any demand pursuant to the provisions of this Section
6.02, shall be entitled and empowered, by intervention in such proceedings or
otherwise:

         (a) to file and prove a claim or claims for the whole amount of
principal and interest owing and unpaid in respect of the Securities of any
series, and to file such other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for
reasonable compensation to the Trustee, its agents and counsel, and for
reimbursement of all expenses and liabilities incurred, and all advances made,
by the Trustee, its agents and counsel except as a result of its negligence or
bad faith) and of the Holders allowed in any judicial proceedings relative to
the Company, the Guarantor or other obligor upon the Securities of any series,
or to the creditors or property of the Company, the Guarantor or such other
obligor; and

         (b) unless prohibited by applicable law and regulations, to vote on
behalf of the Holders of the Securities of any series in any election of a
trustee or a standby trustee in arrangement, reorganization, liquidation or
other bankruptcy or insolvency proceedings or person performing similar
functions in comparable proceedings; and

         (c) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute all amounts received with
respect to the claims of the Holders and of the Trustee on their behalf; and any
receiver, assignee or trustee in bankruptcy or reorganization is hereby
authorized by each of the Holders to make payments to the Trustee and, in the
event that the Trustee shall consent to the making of payments directly to the
Holders, to pay to the Trustee such amount as shall be sufficient to cover
reasonable compensation to the Trustee, its agents and counsel, and all other
expenses and liabilities incurred, and all advances made, by the Trustee, its
agents and counsel except as a result of its negligence or bad faith.

         All rights of action and to assert claims under this Indenture, or
under any of the Securities, may be enforced by the Trustee without the
possession of any of the Securities or the production thereof on any trial or
other proceedings relative thereto, any such action or proceedings instituted by
the Trustee shall be brought in its own name as trustee of an express trust, and
any recovery of judgment shall be for the ratable benefit of the holders of the
Securities.

         In case of a default hereunder the Trustee may in its discretion
proceed to protect and enforce the rights vested in it by the Indenture by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any of such rights, either at law or in equity or in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in aid of the exercise of any power
granted in this Indenture, or otherwise, and the Trustee may enforce any other
legal or equitable right vested in the Trustee by this Indenture or by law.

         SECTION 6.03 Any moneys collected by the Trustee pursuant to Section
6.02 in respect of any series shall be applied in the order following, at the
date or dates fixed by the Trustee and, in case of the distribution of such
moneys on account of principal (or premium, if any) or interest, upon
presentation of the several Securities and stamping thereon the payment if only
partially paid, and upon surrender thereof if fully paid:

                  FIRST: To the payment of costs and expenses of collection,
         reasonable compensation to the Trustee, its agents and counsel, and all
         other expenses and liabilities incurred, and all advances made, by the
         Trustee except as a result of its negligence or bad faith;

                  SECOND: In case the principal of the Securities of such series
         in respect of which moneys have been collected shall not have become
         and be then due and payable, to the payment of interest on the
         Securities of such series in default, in the order of the maturity of
         the installments of such interest, with interest (to the extent that
         such interest has been collected by the Trustee) upon the overdue
         installments of interest at the same rate as the rate of interest
         specified in such Securities, such payments to be made ratably to the
         persons entitled thereto, without discrimination or preference;

                  THIRD: In case the principal of the Securities of such series
         in respect of which moneys have been collected shall have become and
         shall be then due by declaration or otherwise, to the payment of the
         whole amount then owing and unpaid upon the Securities of such series
         for principal (and premium, if any) and interest, with interest upon
         the overdue principal (and premium, if any), and (to the extent that
         such interest has been collected by the Trustee) upon overdue
         installments of interest, at the same rate as the rate of interest
         specified in the Securities of such series; and in case such moneys
         shall be insufficient to pay in full the whole amount so due and unpaid
         upon the Securities of such series, then to the payment of such
         principal (and premium, if any) and interest or Yield to Maturity, as
         the case may be, without preference or priority of principal (and
         premium, if any) over interest, or Yield to Maturity, as the case may
         be, or of interest or Yield to Maturity, as the case may be, over
         principal (and premium, if any), or of any installment of interest over
         any other installment of interest, or of any Security of such series
         over any other Security, ratably to the aggregate of such principal
         (and premium, if any) and interest or Yield to Maturity.

          SECTION 6.04 No Holder of any Security of any series shall have any
right by virtue or by availing of any provision of this Indenture to institute
any action or proceedings at law or in equity or in bankruptcy or otherwise upon
or under or with respect to this Indenture, or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless such Holder previously
shall have given to the Trustee written notice of any Event of Default and
unless also the Holders of not less than twenty-five percent in aggregate
principal amount of the Securities of such series then outstanding shall have
made written request upon the Trustee to institute such action or proceedings in
its own name as trustee hereunder and shall have offered to the Trustee such
indemnity satisfactory to it against the costs, expenses and liabilities to be
incurred therein or thereby and the Trustee, for sixty days after its receipt of
such notice, request and offer of indemnity, shall have failed to institute any
such action or proceedings and no 

                                       29

direction inconsistent with such written request shall have been given to the
Trustee pursuant to Section 6.06; it being understood and intended and being
expressly covenanted by the taker and Holder of every Security with every other
taker and Holder and the Trustee that no one or more Holders of Securities of
any series shall have any right in any manner whatever by virtue or by availing
of any provision of this Indenture to affect, disturb or prejudice the rights of
any other Holder of Securities, or to obtain or seek to obtain priority over or
preference to any other such Holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all Holders of Securities of the applicable series. For the
protection and enforcement of the provisions of this Section 6.04, each and
every Holder and the Trustee shall be entitled to such relief as can be given
either at law or in equity.

          Notwithstanding any other provision in this Indenture, however, the
right of any Holder of any Security to receive payment of the principal of and
interest on such Security, on or after the respective due dates expressed in
such Security, or to institute suit for the enforcement of any such payment on
or after such respective dates, shall not be impaired or affected without the
consent of such Holder.

          SECTION 6.05 All powers and remedies given by this Article Six to the
Trustee or to the Holders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any thereof or of any other powers and remedies
available to the Trustee or the Holders, by judicial proceedings or otherwise,
to enforce the performance or observance of the covenants and agreements
contained in this Indenture, and no delay or omission of the Trustee or of any
Holder of any of the Securities in exercising any right or power accruing upon
any default occurring and continuing as aforesaid shall impair any such right or
power or shall be construed to be a waiver of any such default or an
acquiescence therein; and, subject to the provisions of Section 6.04, every
power and remedy given by this Article Six or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Holders.

         SECTION 6.06 The Holders of a majority in aggregate principal amount of
the Securities of each series affected (with each series voting as a separate
class) at the time outstanding shall have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee,
or exercising any trust or power conferred on the Trustee with respect to the
Securities of such series by this Indenture.

         In the case of any such waiver, the Company, the Guarantor, the Trustee
and the Holders of the Securities shall be restored to their former positions
and rights hereunder, respectively; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

         Upon any such waiver, such default shall cease to exist and be deemed
to have been cured and not to have occurred for every purpose of this Indenture;
but no such waiver shall extend to any subsequent or other default or Event of
Default or impair any right consequent thereon.

         SECTION 6.07 The Trustee shall, within ninety days after the occurrence
of a default, give to all Holders of any series, as the names and addresses of
such Holders appear on 


                                       30
<PAGE>   43

the Securities register, notice by mail of all defaults known to the Trustee,
which have occurred with respect to such series, unless such defaults shall have
been cured before the giving of such notice (the term "default" or "defaults"
for the purposes of this Section 6.07 being hereby defined to be any event or
events, as the case may be, specified in clauses (a), (b), (c), (d), (e), (f),
(g) and (h) of Section 6.01, not including periods of grace, if any, provided
for therein and irrespective of the giving of written notice specified in clause
(c) of Section 6.01; provided, that, except in the case of a default in the
payment of the principal of (or premium, if any) or interest on any of the
Securities of such series, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee, or a
trust committee of directors and/or Responsible Officers, of the Trustee in good
faith determines that the withholding of such notice is in the interests of the
Holders of Securities of such series. The Trustee shall not be deemed to have
knowledge of any default hereunder unless a Responsible Officer of the Trustee
has actual knowledge of the default or the Trustee receives written notice
thereof.

         SECTION 6.08 All parties to this Indenture agree, and each holder of
any Security by his or her acceptance thereof shall be deemed to have agreed,
that any court may in its discretion require, in any suit for the enforcement of
any right or remedy under this Indenture, or in any suit against the Trustee for
any action taken or omitted by it as Trustee, the filing by any party litigant
in such suit of an undertaking to pay the costs of such suit, and that such
court may in its discretion assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in such suit, having
due regard to the merits and good faith of the claims or defenses made by such
party litigant; but the provisions of this Section 6.08 shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Holder, or group
of Holders of Securities of any series, holding in the aggregate more than ten
percent in principal amount of the Securities outstanding of such series, or, in
the case of any suit relating to or arising under clauses (c) and (h) of Section
6.01 (if the suit relates to Securities of more than one but less than all
series), ten percent in aggregate principal amount of Securities Outstanding
affected thereby, or in the case of any suit relating to or arising under
clauses (c) (if the suit relates to all the Securities then Outstanding), (f) or
(g) of Section 6.01, ten percent in aggregate principal amount of all Securities
Outstanding, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest on any Security on
or after the due date expressed in such Security.

         SECTION 6.09 The Company and the Guarantor covenant (to the extent that
it may lawfully do so) that they will not at any time insist upon, or plead, or
in any manner whatsoever claim or take the benefit or advantage of, any usury,
stay or extension law wherever enacted, now or at any time hereafter in force,
that may affect the covenants or the performance of this Indenture; and the
Company and the Guarantor (to the extent that it may lawfully do so) hereby
expressly waive all benefit or advantage of any such law and covenant that they
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

                             CONCERNING THE TRUSTEE

         SECTION 7.01 With respect to the Holders of any series of Securities
issued hereunder, the Trustee, prior to the occurrence of an Event of Default
with respect to the Securities of a particular series and after the curing of
all Events of Default which may have occurred with respect to such series,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture. In case an Event of Default has occurred (which has not
been cured), the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his or her own affairs.

         No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that

                  (a) prior to the occurrence of an Event of Default with
         respect to the Securities of any series and after the curing of all
         Events of Default with respect to such series which may have occurred:

                           (1) the duties and obligations of the Trustee with
                  respect to the Securities of any series shall be determined
                  solely by the express provisions of this Indenture, and the
                  Trustee shall not be liable except for the performance of such
                  duties and obligations as are specifically set forth in this
                  Indenture, and no implied covenants or obligations shall be
                  read into this Indenture against the Trustee; and

                           (2) in the absence of bad faith on the part of the
                  Trustee, the Trustee may conclusively rely, as to the truth of
                  the statements and the correctness of the opinions expressed
                  therein, upon any certificates or opinions furnished to the
                  Trustee and conforming to the requirements of this Indenture;
                  but in the case of any such certificates or opinions which by
                  any provision hereof are specifically required to be furnished
                  to the Trustee, the Trustee shall be under a duty to examine
                  the same to determine whether or not they conform to the
                  requirements of this Indenture;

                  (b) the Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Officer, unless it shall be proved
         that the Trustee was negligent in ascertaining the pertinent facts; and

                  (c) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction of the Holders of not less than a majority in aggregate
         principal amount of Securities of all series at the time outstanding
         (determined as provided in Section 8.03) relating to the time, method
         and 


                                       32
<PAGE>   45

         place of conducting any proceeding for any remedy available to the
         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Indenture.

         No provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder, or in the exercise of any of its rights or
powers, if it shall have reasonable grounds for believing that repayment of such
funds or adequate indemnity against such risk or liability is not reasonably
assured to it.

         SECTION 7.02 Except as otherwise provided in Section 7.01:

                  (a) the Trustee may rely conclusively and shall be protected
         in acting or refraining from acting in reliance upon any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         consent, order, bond, debenture or other paper or document believed by
         it to be genuine and to have been signed or presented by the proper
         party or parties;

                  (b) any request, direction, order, demand, notice or other
         communication of the Company or the Guarantor mentioned herein shall be
         sufficiently evidenced by an instrument signed in the name of the
         Company or the Guarantor by the Chairman of the Board of Directors or a
         Vice Chairman of the Board of Directors or the President or an
         Executive Vice President and the Secretary or an Assistant Secretary or
         the Chief Financial Officer, the Treasurer or an Assistant Treasurer
         (unless other evidence in respect thereof be herein specifically
         prescribed); and any resolution of the Board of Directors may be
         evidenced to the Trustee by a copy thereof certified by the Secretary
         or an Assistant Secretary of the Company or the Guarantor, as the case
         may be;

                  (c) the Trustee may consult with counsel of its selection and
         the advice of such counsel or any Opinion of Counsel shall be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in accordance
         with such Opinion of Counsel;

                  (d) the Trustee shall be under no obligation to exercise any
         rights or powers vested in it by this Indenture at the request, order
         or direction of any of the Securityholders, pursuant to the provisions
         of this Indenture, unless such Securityholders shall have offered to
         the Trustee security or indemnity satisfactory to it against the costs,
         expenses and liabilities which might be incurred therein or thereby;

                  (e) the Trustee shall not be liable for any action taken,
         suffered or omitted by it in good faith and believed by it to be
         authorized or within the discretion or rights or powers conferred upon
         it by this Indenture;

                  (f) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture or other paper or document but the
         Trustee, in its discretion, may make such further inquiry or
         investigation into such facts


                                       33
<PAGE>   46

         or matters as it may see fit, and, if the Trustee shall determine to
         make such further inquiry or investigation, it shall be entitled to
         examine the books, records and premises of the Company, personally or
         by agent or attorney;

                  (g) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys and the Trustee shall not be responsible
         for any misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder; and

                  (h) the rights, privileges, protections, immunities and
         benefits given to the Trustee, including, without limitation, its right
         to be indemnified, are extended to, and shall be enforceable by, the
         Trustee in each of its capacities hereunder, and to each agent,
         custodian or other Person employed to act hereunder.

          SECTION 7.03 The recitals contained herein and in the Securities
(except in the certificates of authentication) shall be taken as the statements
of the Company, and the Trustee assumes no responsibility for the correctness of
the same. The Trustee makes no representations as to the validity or sufficiency
of this Indenture or of the Securities or the Guarantees. The Trustee shall not
be accountable for the use or application by the Company of any of the
Securities or of the proceeds thereof.

          SECTION 7.04 The Trustee or the authenticating agent or any paying
agent or Security registrar, in its individual or any other capacity, may become
the owner or pledgee of Securities with the same rights it would have if it were
not Trustee, authenticating agent, paying agent or Security registrar.

          SECTION 7.05 Subject to the provisions of Section 11.04 hereof, all
moneys received by the Trustee shall, until used or applied as herein provided,
be held in trust for the purposes for which they were received, but need not be
segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on any moneys received by it hereunder
except such as it may agree in writing with the Company to pay thereon. So long
as no Event of Default shall have occurred and be continuing, all interest
allowed on any such moneys shall be paid from time to time upon the written
order of the Company, signed by its Chairman of the Board of Directors or a Vice
Chairman of the Board of Directors or its President or an Executive Vice
President or its Chief Financial Officer or its Treasurer or an Assistant
Treasurer.

          SECTION 7.06 The Company and the Guarantor each covenant and agree to
pay to the Trustee from time to time, and the Trustee shall be entitled to, such
compensation as shall be agreed to by the Company and the Trustee in writing
(which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust) and, except as otherwise
expressly provided, the Company (or the Guarantor, if the Company fails to do
so) will pay or reimburse the Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by the Trustee in
accordance with any of the provisions of this Indenture (including the
compensation and the expenses and disbursements of its counsel and its agents)
except any such expense, disbursement or advance as may arise from its
negligence or 

                                       34
<PAGE>   47

bad faith. If any property other than cash shall at any time be subject to the
lien of this Indenture, the Trustee, if and to the extent authorized by a
receivership or bankruptcy court of competent jurisdiction or by the
supplemental instrument subjecting such property to such lien, shall be entitled
but not required to make advances for the purpose of preserving such property or
of discharging tax liens or other prior liens or encumbrances thereon and the
Trustee shall be entitled to reimbursement thereof. The Company and the
Guarantor also covenant to indemnify the Trustee for, and to hold it harmless
against, any and all damage, claims, loss, liability or expense, including
taxes, incurred without gross negligence or bad faith on the part of the
Trustee, arising out of or in connection with the acceptance or administration
of this trust, including the costs and expenses of defending itself against any
claim or liability in connection with the exercise or performance of any of its
duties hereunder. The obligations of the Company under this Section 7.06 shall
constitute additional indebtedness hereunder. Such additional indebtedness shall
be secured by a lien prior to that of the Securities upon all property and funds
held or collected by the Trustee as such, except funds held in trust for the
benefit of the holders of particular Securities.

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Sections 6.01(f) or Section 6.01(g), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or
other similar law.

         The provisions of this Section shall survive the termination of this
Indenture.

         SECTION 7.07 Except as otherwise provided in Section 7.01, whenever in
the administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, such matter (unless other evidence
in respect thereof be herein specifically prescribed) may, in the absence of
negligence or bad faith on the part of the Trustee, be deemed to be conclusively
proved and established by a certificate signed by the Chairman of the Board of
Directors or a Vice Chairman of the Board of Directors or the President or an
Executive Vice President and by the Chief Financial Officer or the Treasurer or
an Assistant Treasurer of the Company and delivered to the Trustee and such
certificate, in the absence of negligence or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken, suffered or
omitted by it under the provisions of this Indenture upon the faith thereof.

         SECTION 7.08 If the Trustee has or shall acquire any conflicting
interest within the meaning of the Trust Indenture Act of 1939, the Trustee
shall eliminate such interest or resign to the extent and in the manner provided
by and subject to the provisions of the Trust Indenture Act of 1939.

         SECTION 7.09 The Trustee for each series of Securities hereunder shall
at all times be a corporation organized and doing business under the laws of the
United States or of any State or Territory or of the District of Columbia
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least one hundred million dollars and being subject to
supervision or examination by Federal, State, Territorial, or District


                                       35
<PAGE>   48

of Columbia authority. If such corporation publishes reports of condition at
least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section 7.09
the combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 7.09, the Trustee shall resign
immediately in the manner and with the effect specified in Section 7.10.

         SECTION 7.10 (a) The Trustee may at any time resign with respect to one
or more of all series of Securities by giving written notice of resignation to
the Company and to the Guarantor. Upon receiving such notice of resignation the
Company shall promptly appoint a successor trustee by written instrument, in
duplicate, executed by order of the Board of Directors, one copy of which
instrument shall be delivered to the resigning Trustee and one copy to the
successor trustee. If no successor trustee shall have been so appointed and have
accepted appointment within thirty days after the giving of such notice of
resignation, the resigning Trustee may, at the expense of the Company, petition
any court of competent jurisdiction for the appointment of a successor trustee,
or any Securityholder who has been a bona fide holder of a Security or
Securities of the applicable series for at least six months may, subject to the
provisions of Section 6.08, on behalf of himself and all others similarly
situated, petition any such court for the appointment of a successor trustee.
Such court may thereupon, after such notice, if any, as it may deem proper and
prescribe, appoint a successor trustee.

         (b)       In case at any time any of the following shall occur--

                  (1) the Trustee of a series of Securities shall fail to comply
        with the provisions of subsection (a) of Section 7.08 after written
        request therefor by the Company or by any Securityholder who has been a
        bona fide holder of a Security or Securities of the applicable series
        for at least six months, or

                 (2) such Trustee shall cease to be eligible in accordance with
        the provisions of Section 7.09 and shall fail to resign after written
        request therefor by the Company or by any such Securityholder, or

                 (3) such Trustee shall become incapable of acting, or shall be
        adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its
        property shall be appointed, or any public officer shall take charge or
        control of the Trustee or of its property or affairs for the purpose of
        rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company may remove the Trustee of such series of
Security and appoint a successor trustee by written instrument, in duplicate,
executed by order of the Board of Directors, one copy of which instrument shall
be delivered to the Trustee so removed and one copy to the successor trustee,
(ii) subject to the provisions of Section 6.08, any Securityholder who has been
a bona fide Holder of such series of Security for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee of such series of
Securities and the appointment of a successor trustee, or (iii) such Trustee may
petition any court of competent jurisdiction for the appointment of a 


                                       36
<PAGE>   49

successor trustee. Such court may thereupon, after such notice, if any, as it
may deem proper and prescribe, remove the Trustee and appoint a successor
trustee.

         (c) The holders of a majority in aggregate principal amount of the
Securities of a series at the time outstanding may at any time remove the
Trustee of such series of Securities and nominate a successor trustee which
shall be deemed appointed as successor trustee unless within ten days after such
nomination the Company objects thereto, in which case the Trustee so removed or
any Securityholder of the same series, upon the terms and conditions and
otherwise as in subdivision (a) of this Section 7.10 provided, may petition, at
the expense of the Company, any court of competent jurisdiction for an
appointment of a successor trustee. If no successor trustee shall have been so
appointed and have accepted appointment within sixty days after the giving of
such notice of removal, the Trustee being removed may petition, at the expense
of the Company, any court of competent jurisdiction for the appointment of a
successor trustee with respect to the Securities of such series.

         (d) Any resignation or removal of the Trustee of any series of
Securities and any appointment of a successor trustee pursuant to any of the
provisions of this Section 7.10 shall become effective upon acceptance of
appointment by the successor trustee as provided in Section 7.11.

         SECTION 7.11 Any successor trustee appointed as provided in Section
7.10 shall execute, acknowledge and deliver to the Company, to the Guarantor and
to its predecessor trustee an instrument accepting such appointment hereunder,
and thereupon the resignation or removal of the predecessor trustee shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as trustee herein; but, nevertheless, on the written request of the
Company or of the successor trustee, the trustee ceasing to act shall, upon
payment of any amounts then due it pursuant to the provisions of Section 7.06,
execute and deliver an instrument transferring to such successor trustee all of
the rights and powers of the trustee so ceasing to act. Upon request of any such
successor trustee, the Company and the Guarantor shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming to
such successor trustee all such rights and powers. Any trustee ceasing to act
shall, nevertheless, retain a lien upon all property or funds held or collected
by such trustee to secure any amounts then due it pursuant to the provisions of
Section 7.06.

         No successor trustee shall accept appointment as provided in this
Section 7.11 unless at the time of such acceptance such successor trustee shall
be qualified under the provisions of Section 7.08 and eligible under the
provisions of Section 7.09.

         Upon acceptance of appointment by a successor trustee of one or more
series of Securities as provided in this Section 7.11, the Company shall mail
notice of the succession of such trustee hereunder to all Holders of Securities
of such series as the names and addresses of such holders appear upon the
Security Register. If the Company fails to mail such notice in the prescribed
manner within ten days after acceptance of appointment by the successor trustee,
the successor trustee shall cause such notice to be so mailed at the expense of
the Company.

                                       37
<PAGE>   50

         SECTION 7.12 Any corporation into which the Trustee of any series of
Securities may be merged or converted or with which it may be consolidated, or
any corporation resulting from any merger, conversion or consolidation to which
the Trustee of such Securities shall be a party, or any corporation succeeding
to all or substantially all the corporate trust business of the Trustee, shall
be the successor of such Trustee hereunder, provided such corporation shall be
qualified under the provisions of Section 7.08 and eligible under the provisions
of Section 7.09, without the execution or filing of any paper or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

          SECTION 7.13 If and when the Trustee shall be or become a creditor of
the Company (or any other obligor upon the Securities), the Trustee shall be
subject to the provisions of the Trust Indenture Act of 1939 regarding the
collection of claims against the Company (or any such other obligor).

         SECTION 7.14 As long as any of the Securities remain outstanding, there
may be one or more authenticating agents appointed by the Trustee of the
Securities of such series to act on its behalf and subject to its direction in
connection with the authentication of the Securities of such series as set forth
in Articles Two and Three. For all purposes of this Indenture, the
authentication and delivery of Securities by any authenticating agent pursuant
to this Section shall be deemed to be authentication and delivery of such
Securities "by the Trustee." Each such authenticating agent shall at all times
be a corporation organized and doing business under the laws of the United
States or of any State or Territory or of the District of Columbia authorized
under such laws to act as authenticating agent, having a combined capital and
surplus of at least ten million dollars, and being subject to supervision or
examination by Federal, State, Territorial, or District of Columbia authority
and shall be satisfactory to the Company. If such corporation publishes reports
of condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section 7.14, the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published.

         Any corporation into which an authenticating agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which any authenticating agent
shall be a party, or any corporation succeeding to all or substantially all the
corporate agency business of any authenticating agent, shall continue to be the
authenticating agent without the execution or filing of any paper or any further
act on the part of the Trustee of Securities of such series or the
authenticating agent.

         Any authenticating agent may at any time resign by giving written
notice of resignation to the Trustee of the Securities of such series and to the
Company. Such Trustee may at any time terminate the agency of any authenticating
agent by giving written notice of termination to such authenticating agent, to
the Company and to the Guarantor. Upon receiving such a notice of resignation or
upon such a termination, or in case at any time any authenticating agent shall
cease to be eligible in accordance with the provisions of this Section 7.14, the
Trustee promptly shall appoint a successor authenticating agent, if the terms of
this Section 7.14 require that there shall be an authenticating agent, shall
give written notice of such appointment to the Company and to the Guarantor and
shall mail notice of such appointment to all Holders of Securities of such


                                       38
<PAGE>   51

series as the names and addresses of such Holders appear upon the Securities
register. Any successor authenticating agent upon acceptance of its appointment
hereunder shall become vested with all the rights, powers, duties and
responsibilities of its predecessor hereunder, with like effect as if originally
named as authenticating agent herein. No successor authenticating agent shall be
appointed unless eligible under the provisions of this Section 7.14.

         The Company agrees to pay to the authenticating agent from time to time
reasonable compensation for its services.


                                  ARTICLE EIGHT

                         CONCERNING THE SECURITYHOLDERS

         SECTION 8.01 (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by a specified percentage in principal amount of the Securityholders of any or
all series may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such specified percentage of
Securityholders in person or by agent duly appointed in writing; and, except as
herein otherwise expressly provided, such action shall become effective when
such instrument or instruments are delivered to the Trustee, and, where it is
hereby expressly required, to the Company and the Guarantor. Proof of execution
of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Sections 7.01 and
7.02) conclusive in favor of the Trustee and the Company and the Guarantor, if
made in the manner provided in this section.

         (b) Subject to the provisions of Sections 7.01 and 7.02, the execution
of any instrument by a Securityholder or his or her agent or proxy may be proved
in accordance with such reasonable rules and regulations as may be prescribed by
the Trustee or in such manner as shall be satisfactory to the Trustee.

         (c) The holding of Securities shall be proved by the Security Register
or by a certificate of the registrar thereof.

         SECTION 8.02 The Company, the Guarantor, the Trustee, any
authenticating agent, any paying agent and any Securities registrar may deem and
treat the person in whose name any Security shall be registered upon the
Securities register as the absolute owner of such Security (whether or not such
Security shall be overdue and notwithstanding any notation of ownership or other
writing thereon) for the purpose of receiving payment of or on account of the
principal of (and premium, if any) and, subject to the provisions of this
Indenture, interest on such Security and for all other purposes; and neither the
Company, nor the Guarantor nor the Trustee nor any authenticating agent nor any
paying agent nor any Security registrar shall be affected by any notice to the
contrary. All such payments so made to any such person, or upon his order, shall
be valid, and, to the extent of the sum or sums so paid, effectual to satisfy
and discharge the liability for moneys payable upon any such Security.

                                       39
<PAGE>   52

         None of the Company, the Trustee or any agent of the Company or the
Trustee shall have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests of a
Security in global form, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests. Notwithstanding the
foregoing, with respect to any Security in global form, nothing herein shall
prevent the Company or the Trustee, or any agent of the Company or the Trustee,
from giving effect to any written certification, proxy or other authorization
furnished by any Depositary (or its nominee) as a Holder, with respect to such
Security in global form or impair, as between such Depositary and owners of
beneficial interests in such Security in global form, the operation of customary
practices governing the exercise of the rights of such Depositary (or its
nominee) as Holder of such Security in global form.


         SECTION 8.03 In determining whether the Holders of the requisite
aggregate principal amount of Securities of any or all series have concurred in
any demand or request, the giving of any notice, direction, consent or waiver or
the taking of any other action under this Indenture, Securities which are owned
by the Company or the Guarantor or any other obligor on the Securities or by any
person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company or any other obligor on the Securities
shall be disregarded and deemed not to be outstanding for the purpose of any
such determination except that for the purpose of determining whether the
Trustee shall be protected in relying on any such demand, request, notice,
direction, consent or waiver only Securities which a Responsible Officer of the
Trustee actually knows are so owned shall be so disregarded.

         SECTION 8.04 At any time prior to (but not after) the evidencing to the
Trustee, as provided in Section 8.01, of the taking of any action by the Holders
of the percentage in aggregate principal amount of the Securities of any or all
series, as the case may be, specified in this Indenture in connection with such
action, any holder of a Security the serial number of which is shown by the
evidence to be included in the Securities the Holders of which have joined in
such action may, by filing written notice with the Trustee at its office and
upon proof of ownership as provided in Section 8.01, revoke such action so far
as concerns such Security. Except as aforesaid any such action taken by the
Holder of any Security shall be conclusive and binding upon such Holder and upon
all future Holders and owners of such Security and of any Security issued upon
the transfer thereof or in exchange or substitution therefor, irrespective of
whether or not any notation in regard thereto is made upon such Security. Any
action taken by the Holders of the percentage in aggregate principal amount of
the Securities of any or all series, as the case may be, specified in this
Indenture in connection with such action shall be conclusively binding upon the
Company, the Trustee and the Holders of all the Securities affected by such
action.

                                  ARTICLE NINE

                             SUPPLEMENTAL INDENTURES

         SECTION 9.01 The Company and the Guarantor, when authorized by the
resolutions of its Board of Directors, and the Trustee may from time to time and
at any time enter into an indenture or indentures supplemental hereto (which
shall conform to the provisions of the Trust Indenture Act of 1939 as in force
at the date of execution of such supplemental indenture) for one or more of the
following purposes:

                  (a) to evidence the succession of another corporation to the
         Company, or to the Guarantor, or successive successions, and the
         assumption by the successor corporation of the covenants, agreements
         and obligations of the Company or the Guarantor, as the case may be,
         pursuant to Article Ten hereof;

                  (b) to add to the covenants of the Company or the Guarantor
         such further covenants, restrictions, conditions or provisions as the
         Board of Directors of the Company and the Guarantor and the Trustee
         shall consider to be for the protection of the Holders of Securities,
         and to make the occurrence, or the occurrence and continuance, of a
         default in any of such additional covenants, restrictions, conditions
         or provisions a default or an Event of Default permitting the
         enforcement of all or any of the several remedies provided in this
         Indenture; provided, however, that in respect of any such additional
         covenant, restriction, condition or provision such supplemental
         indenture may provide for a particular period of grace after default
         (which period may be shorter or longer than that allowed in the case of
         other defaults) or may provide for an immediate enforcement upon such
         default or may limit the remedies available to the Trustee upon such
         default or may limit the right of the holders of a majority in
         aggregate principal amount of the Securities to waive such default;

                  (c) to provide for the issuance under this Indenture of
         Securities in bearer form (including Securities registrable as to
         principal only) and to provide for exchangeability of such Securities
         with the Securities of the same series issued hereunder in fully
         registered form and to make all appropriate changes for such purposes;

                  (d) to cure any ambiguity or to correct or supplement any
         provision contained herein or in any supplemental indenture which may
         be defective or inconsistent with any other provision contained herein
         or in any supplemental indenture, to convey, transfer, assign, mortgage
         or pledge any property to or with the Trustee or to make such other
         provisions in regard to matters or questions arising under this
         Indenture as shall not adversely affect the interests of the Holders of
         the Securities; and

                  (e) to establish the form or terms of Securities of any series
         as permitted by Sections 2.01, 2.02 or 2.07.

         The Trustee is hereby authorized to join with the Company and the
Guarantor in the execution of any such supplemental indenture, to make any
further appropriate agreements and 


                                       41
<PAGE>   54

stipulations which may be therein contained and to accept the conveyance,
transfer, assignment, mortgage or pledge of any property thereunder, but the
Trustee shall not be obligated to enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

         Any supplemental indenture authorized by the provisions of this Section
9.01 may be executed by the Company, the Guarantor and the Trustee without the
consent of the Holders of any of the Securities at the time outstanding.

         SECTION 9.02 With the consent (evidenced as provided in Section 8.01)
of the Holders of not less than 66 2/3% in aggregate principal amount of the
Securities at the time Outstanding, the Company and the Guarantor, each when
authorized by resolutions of its Board of Directors, and the Trustee may from
time to time and at any time enter into an indenture or indentures supplemental
hereto (which shall conform to the provisions of the Trust Indenture Act of 1939
as in force at the date of execution of such supplemental indenture) for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Indenture or of any supplemental indenture; provided,
however, that without the consent of the Holder of each Outstanding Security
affected thereby, a supplemental indenture under this Section may not:

                  (a) change the stated maturity of the principal of, or
         premium, if any, on, or any installment of principal of or premium, if
         any, or rate of interest, if any, on, any Security, or reduce the
         principal amount thereof or the rate of interest thereon or any premium
         payable upon the redemption, repurchase or repayment thereof, or change
         the manner in which the amount of any principal thereof or premium, if
         any, or rate of interest, if any, thereon is determined or change the
         place of payment where, or impair the right to institute suit for the
         enforcement of any such payment on or after the stated maturity thereof
         (or, in the case of redemption, on or after the redemption date);

                  (b) reduce the percentage in principal amount of the
         Outstanding Securities of such series affected thereby, the consent of
         whose Holders is required for any such supplemental indenture, or the
         consent of whose Holders is required for any waiver (of compliance with
         certain provisions of this Indenture or certain defaults hereunder and
         their consequences) provided for in this Indenture;

                  (c) waive a default in the payment of principal of, premium,
         if any, or interest, if any, on, any Security of such series;

                  (d) change any obligation of the Company to maintain an office
         or agency in the places and for the purposes specified in Section 4.02;
         or

                  (e) make any change in Section 6.01 or this Section except to
         increase any percentage or to provide that certain other provisions of
         this Indenture cannot be modified or waived without the consent of the
         Holders of each Outstanding Security of such series affected thereby,
         except in circumstances beneficial to the Holders.


                                       42
<PAGE>   55

         Upon the request of the Company and the Guarantor, accompanied by a
copy of resolutions of its Board of Directors certified by the Secretary or an
Assistant Secretary authorizing the execution of any such supplemental
indenture, and upon the filing with the Trustee of evidence of the consent of
Securityholders as aforesaid, the Trustee shall join with the Company and the
Guarantor in the execution of such supplemental indenture unless such
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise, in which case the Trustee may in its
discretion but shall not be obligated to enter into such supplemental indenture.

         It shall not be necessary for the Securityholders under this Section
9.02 to consent to the particular form of any proposed supplemental indenture,
but it shall be sufficient if they consent to the substance thereof.

         Promptly after the execution by the Company, the Guarantor and the
Trustee of any supplemental indenture pursuant to the provisions of this Section
9.02, the Company shall mail a notice, setting forth in general terms the
substance of such supplemental indenture, to all Holders of Securities as the
names and addresses of such holders appear upon the Security Register. Any
failure of the Company to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental
indenture.

         SECTION 9.03 Upon the execution of any supplemental indenture pursuant
to the provisions of this Article Nine, this Indenture shall be and be deemed to
be modified and amended in accordance therewith and the respective rights,
limitation of rights, obligations, duties and immunities under this Indenture of
the Trustee, the Company, the Guarantor and the Holders of Securities of each
series shall thereafter be determined, exercised and enforced hereunder subject
in all respects to such modifications and amendments, and all the terms and
conditions of any such supplemental indenture shall be and be deemed to be part
of the terms and conditions of this Indenture for any and all purposes.

         The Trustee, subject to the provisions of Sections 7.01 and 7.02, may
receive an Opinion of Counsel as conclusive evidence that any such supplemental
indenture complies with the provisions of this Article Nine.

         SECTION 9.04 Securities authenticated and delivered after the execution
of any supplemental indenture pursuant to the provisions of this Article Nine
may bear a notation in form approved by the Trustee for such series as to any
matter provided for in such supplemental indenture. New Securities of any series
so modified as to conform, in the opinion of the Trustee and the Board of
Directors, to any modification or amendment of this Indenture contained in any
such supplemental indenture may be prepared and executed by the Company and the
Guarantor, authenticated by the Trustee or by the authenticating agent on its
behalf and delivered in exchange for the Securities then outstanding.

         Every amendment to this Indenture or the Securities of one or more
series shall be set forth in an Officer's Certificate or supplemental indenture
that complies with the Trust Indenture Act as then in effect.

                                   ARTICLE TEN

                    CONSOLIDATION, MERGER, SALE OR CONVEYANCE

         SECTION 10.01 Nothing contained in this Indenture or in any of the
Securities shall prevent any consolidation of the Company with, or merger of the
Company into, any other corporation or corporations (whether or not affiliated
with the Company), or successive consolidations or mergers to which the Company
or its successor or successors shall be a party or parties, or shall prevent any
sale or conveyance of the property of the Company as an entirety or
substantially as an entirety to any other corporation (whether or not affiliated
with the Company) authorized to acquire and operate the same; provided, however,
and the Company hereby covenants and agrees, that:

                  (a) upon any such consolidation, merger, sale or conveyance,
         the due and punctual payment of the principal of (and premium, if any)
         and interest on all of the Securities according to their tenor, and the
         due and punctual performance and observance of all of the covenants and
         conditions of this Indenture to be performed or observed by the
         Company, shall be expressly assumed, by supplemental indenture
         satisfactory in form to the Trustee, executed and delivered to the
         Trustee by the corporation formed by such consolidation, or into which
         the Company shall have been merged, or which shall have acquired such
         property;

                  (b) immediately after giving effect to such transaction, no
         Event of Default, and no event which, after notice of lapse of time, or
         both, would become an Event of Default, shall have happened and be
         continuing; and

                  (c) the corporation formed by such consolidation or into which
         the Company is merged or the person which acquires by conveyance or
         transfer the properties and assets of the Company substantially as an
         entirety shall be a corporation organized and existing under the laws
         of the United States of America or any State thereof or the District of
         Columbia.

         SECTION 10.02 In case of any such consolidation, merger, sale or
conveyance, and following such an assumption by the successor corporation, such
successor corporation shall succeed to and be substituted for the Company, with
the same effect as if it had been named herein.

         Such successor corporation may cause to be signed, and may issue either
in its own name or in the name of the Company prior to such succession, any or
all of the Securities issuable pursuant to the provisions of Section 2.01 which
theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor corporation instead of the
Company and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any
Securities which previously shall have been signed by the officers of the
Company and endorsed with the Guarantee of the Guarantor and delivered to the
Trustee for authentication pursuant to such provisions and any Securities which
such successor corporation thereafter shall cause to be signed and the Guarantor


                                       44
<PAGE>   57

shall cause to be endorsed with the Guarantee and such successor corporation
shall cause to be delivered to the Trustee on its behalf for that purpose
pursuant to such provisions. All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

         In case of any such consolidation, merger, sale or conveyance, such
changes in phraseology and form may be made in the Securities thereafter to be
issued as may be appropriate.

         Nothing contained in this Indenture or in any of the Securities shall
prevent the Company from merging into itself any other corporation (whether or
not affiliated with the Company) or acquiring by purchase or otherwise all or
any part of the property of any other corporation (whether or not affiliated
with the Company).

         SECTION 10.03 The Trustee, subject to the provisions of Sections 7.01
and 7.02, may receive an Opinion of Counsel as conclusive evidence that any
consolidation, merger, sale or conveyance and any such assumption complied with
the provisions of this Article Ten.

         SECTION 10.04 Nothing contained in this Indenture or in any of the
Securities shall prevent any consolidation or merger of the Guarantor with or
into any other corporation or corporations (whether or not affiliated with the
Guarantor), or successive consolidations or mergers in which the Guarantor or
its successor or successors shall be a party or parties, or shall prevent any
sale or conveyance of all or substantially all of the property of the Guarantor
to any other corporation (whether or not affiliated with the Guarantor)
authorized to acquire and operate the same; provided, however, and the Guarantor
hereby covenants and agrees, that:

                  (a) upon any such consolidation, merger, sale or conveyance,
         the due and punctual payment of the principal of (and premium, if any)
         and interest on all of the Guarantees according to their tenor, and the
         due and punctual performance and observance of all of the covenants and
         conditions of this Indenture to be performed or observed by the
         Guarantor, shall be expressly assumed, by supplemental indenture
         satisfactory in form to the Trustee, executed and delivered to the
         Trustee by the corporation formed by such consolidation, or into which
         the Guarantor shall have been merged, or which shall have acquired such
         property;

                  (b) immediately after giving effect to such transaction, no
         Event of Default, and no event which, after notice of lapse of time, or
         both, would become an Event of Default, shall have happened and be
         continuing; and

                  (c) the corporation formed by such consolidation or into which
         the Guarantor is merged or the person which acquires by conveyance or
         transfer the properties and assets of the Guarantor substantially as an
         entirety shall be a corporation organized and existing under the laws
         of the United States of America or any State thereof or the District of
         Columbia.

<PAGE>   58

         SECTION 10.05 In case of any such consolidation, merger, sale or
conveyance and upon the assumption by the successor corporation, by supplemental
indenture executed and delivered to the Trustee and satisfactory in form to the
Trustee, of the Guarantees endorsed upon the Securities and of the due and
punctual performance of all covenants and conditions of this Indenture to be
performed by the Guarantor, such successor corporation shall succeed to and be
substituted for the Guarantor with the same effect as if it had been named
herein as Guarantor. Such successor corporation thereupon may cause to be
executed, either in its own name or in the name of Cincinnati Bell Inc., any or
all of the Guarantees to be endorsed upon all of the Securities issuable
hereunder which theretofore shall not have been signed by the Company and
delivered to the Trustee.


                                 ARTICLE ELEVEN

                    SATISFACTION AND DISCHARGE OF INDENTURE;
                                UNCLAIMED MONEYS

         SECTION 11.01 If at any time (a) the Company shall have delivered to
the Trustee cancelled or for cancellation all Securities theretofore
authenticated (other than any Securities of such series which shall have been
destroyed, lost or stolen and which shall have been replaced or paid as provided
in Section 2.11), or (b) the Company or the Guarantor shall deposit or cause to
be deposited with the Trustee as trust funds, money or U.S. Government
Obligations in an amount sufficient to pay all principal (and premium, if any)
and interest and any other sums due or to become due to the date of maturity or
redemption of such series of securities, but excluding, however, the amount of
any moneys for the payment of principal of (and premium, if any) or interest on
the Securities of such series (1) theretofore deposited with the Trustee and
repaid by the Trustee to the Company in accordance with the provisions of
Section 11.04, or (2) paid to any State or to the District of Columbia pursuant
to its unclaimed property or similar laws, and if in either case the Company
shall also pay or cause to be paid all other sums payable hereunder by the
Company, then this Indenture shall cease to be of further effect (except as to
(i) the provisions applicable to transfers and exchange of the Securities of
such series or (ii) the rights of Holders to receive payments of principal
thereof and interest thereon, and remaining rights of the Holders to receive
mandatory sinking fund payments, if any) and the Trustee, on demand of and at
the cost and expense of the Company, shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture, provided that in
the case of a discharge pursuant to clause (b), the Company has delivered to the
Trustee an opinion of a nationally recognized independent tax counsel to the
Company experienced in such matters to the effect that the Holders will not
recognize income, gain or loss for U.S. federal income tax purposes as a result
of the deposit and discharge pursuant to clause (b) and will be subject to U.S.
federal income tax on the same amount, in the same manner and at the same times
as would have been the case if such deposit and discharge had not occurred. The
Company agrees to reimburse the Trustee for any costs or expenses thereafter
reasonably and properly incurred by the Trustee in connection with this
Indenture or the Securities of such series.

         SECTION 11.02 All moneys deposited with the Trustee pursuant to Section
11.01 shall be held in trust and applied by it to the payment, either directly
or through any paying agent

(including the Company acting as its own paying agent), to the Holders of the
particular Securities of such series for the payment of which such moneys have
been deposited with the Trustee, of all sums due and to become due thereon for
principal (and premium, if any) and interest.

         SECTION 11.03 In connection with the satisfaction and discharge of this
Indenture all moneys then held by any paying agent under the provisions of this
Indenture shall, upon demand of the Company, be repaid to it or paid to the
Trustee and thereupon such paying agent shall be released from all further
liability with respect to such moneys.

         SECTION 11.04 Any moneys deposited with or paid to the Trustee or any
paying agent pursuant to any provision of this Indenture for payment of the
principal of (and premium, if any) or interest on any Security of any series and
not applied but remaining unclaimed by the Holders of the Securities of such
series for two years after the date upon which the principal of (and premium, if
any) or interest on such Securities, as the case may be, shall have become due
and payable, shall be repaid to the Company by the Trustee or such paying agent
on written demand; and the Holder of any of the Securities of such series shall
thereafter look only to the Company for any payment which such holder may be
entitled to collect.


                                 ARTICLE TWELVE

                    IMMUNITY OF INCORPORATORS, SHAREHOLDERS,
                        OFFICERS, DIRECTORS AND EMPLOYEES

         SECTION 12.01 No recourse under or upon any obligation, covenant or
agreement of this Indenture, or of any Security of any series, or for any claim
based thereon or otherwise in respect thereof, shall be had against any
incorporator, shareholder, officer, director or employee, as such, past, present
or future, of the Company or of the Guarantor or any successor corporation,
either directly or through the Company or the Guarantor or any successor
corporation, whether by virtue of any constitution, statute or rule of law or by
the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this Indenture and
the issue of the Securities.


                                ARTICLE THIRTEEN

                      PARTICULAR COVENANT OF THE GUARANTOR

         SECTION 13.01 So long as any of the Securities of any series remain
outstanding, the Guarantor will maintain in the Borough of Manhattan, The City
of New York, State of New York, an office or agency where notices to and demands
or upon the Guarantor in respect of the Securities or of this Indenture may be
served and where the Securities may be presented for payment under the
Guarantees, provided that the Guarantor may maintain in Manhattan a separate
office or agency for one or more of the foregoing purposes. The Guarantor will
give to


                                       47
<PAGE>   60

the Trustee notice of the location of each such office and agency and of any
change in the location of any such office or agency. In case the Guarantor shall
fail to maintain any such office or agency or shall fail to give such notice of
the location or of any change in the location thereof, presentations and demands
may be made and notices may be served at the principal corporate trust office of
the Trustee.


                                ARTICLE FOURTEEN

                           SUBORDINATION OF GUARANTEES

         SECTION 14.01 Notwithstanding anything to the contrary contained in
this Indenture, the Company and the Guarantor each covenant and agree, and each
Holder of Securities, by his or her acceptance thereof, likewise covenants and
agrees, that the Guarantees shall, to the extent and in the manner hereinafter
in this Article Fourteen set forth, be subordinated and subject in right of
payment to the prior payment in full of all Senior Indebtedness of the
Guarantor.

         SECTION 14.02     The Guarantor:

         (a) may not make any payment upon or in respect of the Guarantees
(other than distributions made from any trust created pursuant to Section 11.01
hereof) if:

                  (i) default in the payment of any principal, premium, if any,
         or interest with respect to any Senior Indebtedness occurs and is
         continuing beyond any applicable grace period in the agreement,
         indenture or other document governing the Senior Indebtedness; or

                  (ii) any other default occurs and is continuing with respect
         to any Senior Indebtedness which permits holders of such Senior
         Indebtedness as to which such default relates to accelerate its
         maturity and the Trustee receives a notice of such default (a "Payment
         Blockage Notice") from a person who may give it pursuant to Section
         14.11 hereof. If the Trustee receives any such Payment Blockage Notice,
         no subsequent Payment Blockage Notice shall be effective for purposes
         of this Section 14.03 unless and until at least 360 days shall have
         elapsed since the effectiveness of the immediately prior Payment
         Blockage Notice. No default specified in this clause (ii) that existed
         or was continuing on the date of delivery of any Payment Blockage
         Notice to the Trustee shall be, or be made, the basis for a subsequent
         Payment Blockage Notice, unless such default has been cured or waived
         for a period of not less than 90 days.

         (b) may and shall resume payments on the Guarantees upon the earlier
of:

                  (i) in the case of a default referred to in Section
         14.02(a)(i), the date upon which such default is cured or waived, or

                  (ii) in the case of a default referred to in Section
         14.02(a)(ii) hereof, the earlier of the date on which such default is
         cured or waived or 179 days after the date on which


                                       48
<PAGE>   61

         the applicable Payment Blockage Notice is received, unless the maturity
         of such Senior Indebtedness has been accelerated.

         SECTION 14.03 Upon any payment or distribution of assets of the
Guarantor of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding-up or total or partial liquidation or
reorganization or the Guarantor, whether voluntary or involuntary or in
bankruptcy, insolvency, receivership or other proceedings, full payment of all
amounts of principal (and premium, if any) and interest then due on all Senior
Indebtedness of the Guarantor shall first be made or duly provided for in money
or money's worth before the holders of the indebtedness evidenced by the
Securities or the Trustee under this Indenture shall be entitled to retain any
assets so paid or distributed pursuant to the Guarantees in respect of the
Securities of any series (for principal (and premium, if any) or interest) or of
this Indenture; and upon any such dissolution or winding-up or liquidation or
reorganization, any payment or distribution of assets of the Guarantor of any
kind or character, whether in case, property or securities, to which the Holders
of the Securities of such series or the Trustee under this Indenture would be
entitled pursuant to the Guarantees except for the provisions of this Article
Fourteen shall be paid, by the Guarantor or by any receiver, trustee in
bankruptcy, liquidating trustee, agent or other person making such payment or
distribution directly to the holders of Senior Indebtedness of the Guarantor or
their representatives, to the extent necessary to make full payment of all
amounts of principal (and premium, if any) and interest due on all such Senior
Indebtedness of the Guarantor, in money or money's worth, after giving effect to
any concurrent payments or distributions to, or for the benefit of, the holders
of such Senior Indebtedness of the Guarantor, before any payment or distribution
is made to the holders of the indebtedness evidenced by the Securities or to the
Trustee under this Indenture, provided, however, that nothing in this Section
14.03 shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 7.06.

         SECTION 14.04 In the event that the Trustee or any Holder receives any
payment of any obligations with respect to the Guarantees at a time when the
Trustee or such Holder, as applicable, has actual knowledge that such payment is
prohibited by Sections 14.02 and 14.03 hereof, such payment shall be held by the
Trustee or such Holder, in trust for the benefit of, and shall be paid
immediately, upon written request, to the holders of Senior Indebtedness for
application to the payments due under such Senior Indebtedness remaining unpaid
to the extent necessary to cover all such payments due in full in accordance
with their terms, after giving effect to any concurrent payment or distribution
to or for the holders of Senior Indebtedness.

         SECTION 14.05 The Guarantor shall give prompt written notice to the
Trustee of any dissolution, winding-up, liquidation or reorganization of the
Guarantor within the meaning of this Article Fourteen. Upon any payment or
distribution of assets of the Guarantor referred to in this Article Fourteen,
the Trustee, subject to the provisions of Section 7.01, shall be entitled to
rely upon a certificate of the receiver, trustee in bankruptcy, liquidating
trustee, agent or other person making such payment or distribution, delivered to
the Trustee or to the Holders of Securities, for the purpose of ascertaining the
persons entitled to participate in such distribution, the holders of Senior
Indebtedness of the Guarantor and other indebtedness of the Guarantor, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article Fourteen.

                                       49
<PAGE>   62

         The Guarantor and the Company each agree to notify promptly the Trustee
of any other facts known to either the Guarantor or the Company that could cause
a payment of any obligations with respect to the Guarantees in contravention of
this Article Fourteen, but failure to give such notice shall not affect the
subordination of the Guarantees to Senior Indebtedness as provided in this
Article Fourteen.

         SECTION 14.06 Subject to the payment in full of all amounts of
principal (and premium, if any) and interest due on all Senior Indebtedness of
the Guarantor, the holders of the Securities of any series shall be subrogated
pro rata (based on respective amounts paid over for the benefit of the holders
of such Senior Indebtedness of the Guarantor) with the holders of any other
subordinated indebtedness of the Guarantor that by its terms ranks pari passu
with the Guarantees (such subordinated indebtedness being hereinafter in this
Section 14.06 referred to as "pari passu indebtedness") to the rights of the
holders of Senior Indebtedness of the Guarantor to receive payments or
distributions of assets of the Guarantor made on Senior Indebtedness of the
Guarantor until the principal of (and premium, if any) and interest on the
Securities of such series shall be paid in full; and, for the purposes of such
subrogation, no payments or distributions to the holders of Senior Indebtedness
of the Guarantor to which the Holders of the Securities of such series or the
holders of pari passu indebtedness, or the Trustee or the trustee with respect
to any pari passu indebtedness would be entitled except for the provisions of
this Article Fourteen shall, as between the Guarantor, its creditors other than
the holders of Senior Indebtedness of the Guarantor and the Holders of the
Securities of such series and the holders of pari passu indebtedness be deemed
to be a payment by the Guarantor on account of the Guarantees, it being
understood that the provisions of this Article Fourteen are and are intended
solely for the purpose of defining the relative rights of the Holders of the
Securities of such series, the holders of pari passu indebtedness and the
holders of Senior Indebtedness of the Guarantor.

         SECTION 14.07 Nothing contained in this Article Fourteen or elsewhere
in this Indenture, in the Securities of any series or in the Guarantees, is
intended to or shall impair, as among the Guarantor, its creditors other than
the holders of Senior Indebtedness of the Guarantor, and the Holders of the
Securities of such series, the obligation of the Guarantor set forth in Section
2.16 or is intended to or shall affect the relative rights of the Holders of the
Securities of such series or of other pari passu indebtedness and other
creditors of the Guarantor other than the holders of Senior Indebtedness of the
Guarantor, nor shall anything herein or therein prevent the Trustee or (subject
to the provisions of Section 6.04) the Holder of any Securities of such series
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the rights, if any, under this Article Fourteen
of the holders of Senior Indebtedness of the Guarantor in respect of cash,
property or securities of the Guarantor received upon the exercise of any such
remedy.

         Nothing contained in this Article Fourteen or elsewhere in this
Indenture, in the Securities of any series or in the Guarantees, is intended to
or shall impair the obligation of the Company, which is absolute and
unconditional and not subordinate to any other obligation of the Company, to pay
the principal of (and premium, if any) and interest on the Securities of such
series, as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the rights against the Company of
the Holders of the Security of such 


                                       50
<PAGE>   63

series, nor shall anything herein or therein prevent the Trustee or (subject to
the provisions of Section 6.04) the Holder of any security of such series from
exercising all remedies relative to the Company permitted by applicable law upon
default under this Indenture.

         SECTION 14.08 Nothing contained in this Article Fourteen or elsewhere
in this Indenture, or in the Securities of any series or in the Guarantees, is
intended to or shall prevent the Guarantor from making any payment pursuant to
the Guarantees of the principal of (and premium, if any) or interest on the
Securities of such series at any time except under the conditions described in
Section 14.02 or during the pendency of any dissolution, winding-up, liquidation
or reorganization of the Guarantor, provided, however, that payments by the
Guarantor pursuant to the Guarantees may be made during the pendency of any such
proceedings of the Company.

         SECTION 14.09 Each Holder of Securities by his or her acceptance
thereof authorizes and directs the Trustee in its behalf to take such action as
may be necessary or appropriate to effectuate the subordination as provided in
this Article Fourteen and appoints the Trustee his or her attorney-in-fact for
any and all such purposes.

         SECTION 14.10 The Trustee shall be entitled to all of the rights set
forth in this Article Fourteen in respect of any Senior Indebtedness of the
Guarantor at any time held by it, to the same extent as any other holder of
Senior Indebtedness of the Guarantor, and nothing in this Indenture shall
deprive the Trustee of any of its rights as such holder.

         SECTION 14.11 Notwithstanding any of the provisions of this Article
Fourteen or any other provision of this Indenture, the Trustee shall not at any
time be charged with knowledge of the existence of any facts which would
prohibit the making of any payment of moneys to or by the Trustee, unless and
until the Trustee shall have received written notice thereof at the principal
corporate trust office of the Trustee from the Guarantor, from a Representative
or, only in cases where there is no Representative, from one or more holders of
Senior Indebtedness of the Guarantor, and, prior to the receipt of any such
written notice, the Trustee, subject to the provisions of Section 7.01, shall be
entitled to assume that no such facts exist; provided, that, if not less than
three business days prior to the date upon which by the terms hereof any such
moneys may become payable for any purpose (including, without limitation, the
payment of either the principal (and premium, if any) or interest on any
Security) the Trustee shall not have received with respect to such moneys the
notice provided for in this Section 14.11, then, anything herein contained to
the contrary notwithstanding, the Trustee shall have full power and authority to
receive such moneys and to apply the same to the purpose for which they were
received, and shall not be affected by any notice to the contrary which may be
received by it on or after such date.

         SECTION 14.12 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 Senior Indebtedness to participate in any payment or distribution
pursuant to this Article Fourteen, the Trustee may request such person to
furnish evidence to the reasonable satisfaction of the Trustee as to the amount
of Senior Indebtedness of the Guarantor 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 


                                       51
<PAGE>   64

the rights of such person under this Article Fourteen, 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 14.13 With respect to the holders of Senior Indebtedness of 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
Fourteen, and no implied covenants or obligations with respect to the holders of
Senior Indebtedness of the Guarantor shall be read into this Indenture against
the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness of the Guarantor and shall not be liable to any
holder of Senior Indebtedness of the Guarantor if it shall pay over or deliver
to Holders of Securities, the Company or any other person, moneys or assets to
which any holder of Senior Indebtedness of the Guarantor shall be entitled by
virtue of this Article Fourteen or otherwise.

         SECTION 14.14 If payment of the Guarantees is accelerated because of an
Event of Default of the Company, the Guarantor shall promptly notify holders of
Senior Indebtedness of the acceleration.

         SECTION 14.15 This Article 14 shall not apply to any payments to be
made on the Securities from funds held in trust pursuant to Article 11 provided
that this Article 14 did not prohibit the deposit of such funds into trust at
the time of such deposit.

         SECTION 14.16 Notwithstanding anything herein contained to the
contrary, all the provisions of this Indenture shall be subject to the
provisions of this Article Fourteen, so far as the same may be applicable
thereto.

                                 ARTICLE FIFTEEN

                            MISCELLANEOUS PROVISIONS

         SECTION 15.01 All the covenants, stipulations, promises and agreements
in this Indenture contained by or in behalf of the Company or the Guarantor

executed by authority of two-thirds of its Board of Directors and delivered to
the Trustee may surrender any of the powers or rights reserved to the Company or
the Guarantor and thereupon such power or right so surrendered shall terminate
as to the Company and the Guarantor and as to any successor corporations.

Securityholder to or upon the Trustee shall be deemed to have been sufficiently
given or made for all purposes if given or made in writing at the principal
corporate trust office of the Trustee.

         SECTION 15.05 Upon any application or demand by the Company or the
Guarantor to the Trustee to take any action under any of the provisions of this
Indenture, the Company or the Guarantor shall furnish to the Trustee an
Officers' Certificate stating that all conditions precedent provided for in this
Indenture relating to the proposed action have been complied with and an Opinion

                      GUARANTEED ON A SUBORDINATED BASIS BY

                              CINCINNATI BELL INC.


         CINCINNATI BELL TELEPHONE COMPANY, an Ohio corporation (the "Company,"
which term includes any successor corporation under the Indenture referred to
below), for value received, hereby promises to pay to CEDE & CO., as the nominee
of The Depositary Trust Company ("DTC"), or registered assigns, the principal
sum of ONE HUNDRED FIFTY MILLION DOLLARS ($150,000,000) on December 1, 2028, and
to pay interest thereon semiannually in arrears on each June 1 and December 1
(each, an "Interest Payment Date"), commencing on June 1, 1999, and at maturity,
from November 30, 1998 or from the most recent Interest Payment Date to which
interest has been paid or duly provided for, at the rate of 6.30% per annum,
until the principal hereof becomes due and payable, and at such rate on any
overdue 


                                      A-1
<PAGE>   69

principal and (to the extent that the payment of such interest shall be legally
enforceable) on any overdue installment of interest.

         The interest payable hereunder, and punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the Person in whose name this
Debenture is registered at the close of business on the regular record date for
such interest, which shall be the May 15 or November 15 (whether or not a
Business Day), as the case may be, next preceding such Interest Payment Date. If
and to the extent the Company shall default in the payment of the interest due,
if any, on such Interest Payment Date, such defaulted interest shall be paid to
the Persons in whose names the Debentures are registered at the close of
business on a special record date established for such payment by notice by or
on behalf of the Company to the Holders of the Securities not less than fifteen
days prior to such special record date, such special record date to be not less
than five days preceding the date of payment of such defaulted interest, all as
more fully provided in the Indenture.

         Interest shall be computed on the basis of a 360-day year consisting of
twelve 30-day months. Each payment of interest in respect of an Interest Payment
Date shall include interest accrued through the day prior to such Interest
Payment Date. If an Interest Payment Date shall not be a Business Day, then
payment of interest need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on such
Interest Payment Date, and no interest shall accrue for the period after such
date. "Business Day" with respect to the Debentures means a day that is neither
a legal holiday nor a day on which banking institutions are authorized by law to
close in New York, New York.

         Payment of the principal of (and premium, if any) and interest on this
Debenture shall be made at the office or agency of the Company in the Borough of
Manhattan, The City of New York, State of New York. Payment of the principal of
(and premium, if any) and interest on this Debenture shall be payable in
immediately available funds; provided, however, that payment of interest may be
made at the option of the Company by check mailed to the address of the person
entitled thereto at such address as it shall appear on the Debenture register.
Holders of over $5 million in principal amount of Debentures have the option of
receiving payment by wire by notifying the Paying Agent one business day prior
to the payment date. Payment of the principal of (and premium, if any) and
interest on this Debenture shall be made in such coin or currency of the United
States of America as at the time of payment shall be legal tender for the
payment of public and private debts. Interest payable on any Interest Payment
Date will be paid to DTC with respect to the portion of this Debenture held for
its account by CEDE & CO. for the purpose of permitting such party to credit the
interest received by it in respect of this Debenture to the accounts of the
beneficial owners hereof.

         Reference is hereby made to the further provisions of this Debenture
set forth on the reverse hereof and such further provisions shall for all
purposes have the same effect as though fully set forth at this place.


         This Debenture shall not be valid or become obligatory for any purpose
until the appropriate certificate of authentication hereon shall have been
executed by or on behalf of the Trustee under the Indenture referred to on the
reverse hereof.

                       GUARANTEED 6.30% DEBENTURE DUE 2028

                      GUARANTEED ON A SUBORDINATED BASIS BY

                              CINCINNATI BELL INC.


         This Debenture is one of a duly authorized issue of unsecured senior
debt securities of the Company known as the Company's Guaranteed 6.30%
Debentures due 2028 (herein called the "Debentures"), issued under an Indenture
dated as of November 30, 1998 (such Indenture as originally executed and
delivered and as hereafter supplemented or amended, together with the Board
Resolution setting forth certain terms of the Debentures adopted on September
18, 1998 and delivered to the Trustee by the Company pursuant to Section 2.07 of
such Indenture, being herein called the "Indenture") from the Company to The
Bank of New York, as trustee (herein called the "Trustee," which term includes
any other successor trustees under the Indenture), to which Indenture, all
indentures supplemental thereto and all Board Resolutions relating thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Guarantor, the
Trustee and the Holders of the Debentures and of the terms upon which the
Debentures are, and are to be, authenticated and delivered. The acceptance of
this Debenture shall be deemed to constitute the consent and agreement of the
Holders hereof to all of the terms and provisions of the Indenture. All
capitalized terms used in this Debenture which are not defined herein shall have
the meaning assigned to them in the Indenture.

         This Debenture shall be redeemable, as a whole or in part, at the
option of the Company, at any time or from time to time, at a redemption price
(the "Redemption Price") equal to the greater of (i) 100% of the principal
amount hereof and (ii) the sum of the present values of the Remaining Scheduled
Payments discounted to the Redemption Date on a semiannual basis (assuming a
360-day year consisting of twelve 30-day months) at the Treasury Rate plus
twenty basis points, plus, in the case of each of (i) and (ii), accrued interest
thereon to the Redemption Date. Notice of redemption shall be given by mail to
Debenture holders, not less than 30 days nor more than 60 days prior to the
Redemption Date, all as provided in the Indenture. On or prior to the Redemption
Date, the Company shall deposit with the Trustee or with a paying agent, if one
is so appointed in a manner not inconsistent with the Indenture, an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, the Debentures to
be redeemed on such date. In the event of redemption of this Debenture in part
only, a new Debenture or Debentures, of like tenor, for the unredeemed portion
hereof will be issued in the name of the holder hereof upon the surrender
hereof. Subject to the terms of the Indenture, on and after the Redemption Date,


                                      A-4
<PAGE>   72

interest will cease to accrue on this Debenture (or any portion thereof) if so
called for redemption.

         "Comparable Treasury Issue" means the United States Treasury security
selected by the Independent Investment Banker as having a maturity comparable to
the remaining term of the Debentures to be redeemed that would be utilized, at
the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities with respect to comparable
maturity to the remaining term of the Debentures.

         "Comparable Treasury Price" means, with respect to any Redemption Date,
the average of three Reference Treasury Dealer Quotations obtained by the
Trustee for the Redemption Date.

         "Independent Investment Banker" means Salomon Smith Barney Inc., or its
successor.

         "Redemption Date," when used with respect to any Debenture to be
redeemed, in whole or in part, means the date fixed for such redemption pursuant
to the Indenture.

         "Reference Treasury Dealers" means Salomon Smith Barney Inc. or its
successor (so long as it, or its successor, continues to be a primary U.S.
government securities dealer) and any two other primary U.S. government
securities dealers chosen by the Company. If Salomon Smith Barney Inc. ceases to
be a primary U.S. government securities dealer, the Company shall appoint in its
place another nationally recognized investment banking firm that is a primary
U.S. government securities dealer.

         "Reference Treasury Dealer Quotations" means the average, as determined
by the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by three Reference Treasury Dealers at 3:30 p.m. New York
City time on the third Business Day preceding the Redemption Date.

         "Remaining Scheduled Payments" means, with respect to each Debenture to
be redeemed, the remaining scheduled payments of the principal thereof and
interest thereon that would be due after the related Redemption Date but for
such redemption; provided, however, that, if such Redemption Date is not an
Interest Payment Date with respect to such Debenture, the amount of the next
succeeding scheduled interest payment thereon will be reduced by the amount of
interest accrued thereon to such Redemption Date.

         "Treasury Rate" means, with respect to any Redemption Date, the rate
per annum equal to the semiannual equivalent yield to maturity (computed as of
the third Business Day immediately preceding such Redemption Date) of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such Redemption Date.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal hereof 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.

                                      A-5
<PAGE>   73

         The Indenture contains provisions permitting the Company, the Guarantor
and the Trustee, with the consent of the holders of not less than 66 2/3% in
aggregate principal amount of the Debentures at the time outstanding, evidenced
as in the Indenture provided, to execute supplemental indentures adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or of any supplemental indenture or modifying in any manner the
rights of the holders of the Debentures; provided, however, that no such
supplemental indenture shall (i) extend the fixed maturity of any Debentures, 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 Debenture so affected, or
(ii) reduce the aforesaid percentage of Debentures, the consent of the holders
of which is required for any such supplemental indenture, without the consent of
the holders of all Debentures then outstanding. It is also provided in the
Indenture that the holders of a majority in aggregate principal amount of the
Debentures at the time outstanding may on behalf of the holders of all of the
Debentures waive any past default under the Indenture and its consequences,
except a default in the payment of the principal of (or premium, if any) or
interest on any of the Debentures. Any such consent or waiver by the holder of
any Debenture (unless revoked as provided in the Indenture) shall be conclusive
and binding upon such holder and upon all future holders and owners of such
Debenture and of any Debenture issued upon the transfer thereof or in exchange
or substitution therefor, irrespective of whether or not any notation of such
consent or waiver is made upon such Debenture or such other Debenture.

         No reference herein to the Indenture and no provision of this Debenture
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 Debenture at the places, at the respective times, at the rate
and in the coin or currency herein prescribed.

         The Debentures are issuable as registered Debentures without coupons in
denominations of $1,000 and any integral multiple of $1,000. At the office or
agency of the Company referred to on the face hereof and in the manner and
subject to the limitations provided in the Indenture, Debentures may be
exchanged without a service charge for a like aggregate principal amount of
Debentures of other authorized denominations.

         The Debentures may be represented by one or more global Debentures
deposited with The Depository Trust Company ("DTC") and registered in the name
of the nominee of DTC, with certain limited exceptions. So long as DTC or any
successor depositary or its nominee is the registered Holder of a global
Debenture, DTC, such depositary or such nominee, as the case may be, will be
considered to be the sole Holder of the Debentures for all purposes of the
Indenture. Except as provided below, an owner of a beneficial interest in a
global Debenture will not be entitled to have Debentures represented by such
global Debenture registered in such owner's name, will not receive or be
entitled to receive physical delivery of the Debentures in certificated form and
will not be considered the owner or Holder thereof under the Indenture. Each
person owning a beneficial interest in a global Debenture must rely on DTC's
procedures and, if such person is not a participant, on the procedures of the
participant through which such person owns its interest, to exercise any rights
of a Holder under the Indenture. If the Company requests any action of Holders
or if an owner of a beneficial interest in a global Debenture desires to take
any action that a Holder is entitled to take under the Indenture, DTC will
authorize the participants 


                                      A-6
<PAGE>   74

holding the relevant beneficial interests to give or take such action, and such
participants will otherwise act upon the instructions of beneficial owners
holding through them.

         If at any time DTC notifies the Company that it is unwilling or unable
to continue as depositary for the global Debenture or Debentures or if at any
time DTC ceases to be a clearing agency registered under the Securities Exchange
Act of 1934, as amended, if so required by applicable law or regulation, the
Company shall appoint a successor depositary with respect to such global
Debenture or Debentures. If a successor depositary for such global Debenture or
Debentures is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such unwillingness, inability or
ineligibility or the Company, in its sole discretion, determines at any time
that all Outstanding Debentures (but not less than all) issued or issuable in
the form of one or more global Debentures shall no longer be represented by such
global Debentures, then the Company shall execute, and the Trustee shall
authenticate and deliver, definitive Debentures of like series, rank, tenor and
terms in definitive form in an aggregate principal amount equal to the principal
amount of such global Debenture or Debentures. If any beneficial owner of an
interest in a permanent global Debenture is otherwise entitled to exchange such
interest for Debentures of such series and of like tenor and principal amount of
another authorized form and denomination, as contemplated by the Indenture and
provided that any applicable notice provided in the permanent global Debenture
shall have been given, then without unnecessary delay, the Company shall
execute, and the Trustee shall authenticate and deliver, definitive Debentures
in aggregate principal amount equal to the principal amount of such beneficial
owner's interest in such permanent global Debenture.

         Upon the exchange of a Debenture in global form for Debentures in
certificated form, such Debenture in global form shall be canceled by the
Trustee. Debentures in certificated form issued in exchange for a Debenture in
global form shall be registered in such names and in such authorized
denominations as the depositary for such Debenture in global form, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Debentures to the Persons
in whose names such Debentures are so registered.

         None of the Company, the Trustee, any paying agent or the security
registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in this Debenture in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee, or any agent of the Company or the Trustee, from giving effect to any
written certification, proxy or other authorization furnished by any depositary,
as a Holder, with respect to this Debenture in global form or impair, as between
such depositary and owners of beneficial interests in such global Debenture, the
operation of customary practices governing the exercise of the rights of such
depositary (or its nominee) as Holder of such global Debenture.

         Upon due presentment for registration of transfer of this Debenture at
the above-mentioned office or agency of the Company, a new Debenture or
Debentures, of authorized denominations, for a like aggregate principal amount,
will be issued to the transferee as provided in the Indenture. No service charge
shall be made for any such transfer, but the 


                                      A-7
<PAGE>   75

Company may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto.

         The Company, the Guarantor, the Trustee, the authenticating agent, any
paying agent and any Debenture registrar may deem and treat the holder hereof as
the absolute owner hereof (whether or not this Debenture shall be overdue and
notwithstanding any notation of ownership or other writing hereon) for the
purpose of receiving payment of or on account of the principal hereof (and
premium, if any) and, subject to the provisions on the face hereof, interest
hereon, and for all other purposes, and neither the Company nor the Trustee nor
the authenticating agent nor any paying agent nor any Debenture registrar shall
be affected by any notice to the contrary.

         No recourse shall be had for the payment of the principal of (or
premium, if any) or the interest on this Debenture or for any claim based
hereon, or otherwise in respect hereof, or based on or in respect of the
Indenture or any indenture supplemental thereto, against any incorporator,
shareholder (other than the Guarantor, to the extent of its obligations under
the Guarantee endorsed hereon), officer, director or employee, as such, past,
present or future, of the Company or of the Guarantor or of any successor
corporation, either directly or through the Company or the Guarantor or any
successor corporation, whether by virtue of any constitution, statute or rule of
law or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of the consideration for
the issue hereof, expressly waived and released.

         This Debenture shall be deemed a contract made under the laws of the
State of New York and for all purposes shall be governed by and construed in
accordance with the laws of said State.

         FOR VALUE RECEIVED, Cincinnati Bell Inc., a corporation duly organized
and existing under the laws of the State of Ohio (herein called the
"Guarantor"), hereby guarantees to the holder of the Debenture upon which this
Guarantee is endorsed the payment of the principal of (and premium, if any) and
interest on said Debenture (including the costs and expenses of collection), in
accordance with the terms thereof and of the Indenture referred to therein. In
the event of any assignment of said Debenture, the Guarantor shall have all
defenses against the assignee which the Company or the Guarantor may have
against the assignor or any prior assignors. The Guarantor hereby covenants that
this Guarantee will not be discharged except by payment in full of the principal
of (and premium, if any) and interest on said Debenture (including the costs and
expenses of collection).

         The Guarantor shall be subrogated to all rights of the holder of said
Debenture 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 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 Debentures issued under said Indenture held
by others (including the costs and expenses of collection) shall have been paid
in full.

         The obligations evidenced by this Guarantee shall be, to the extent and
in the manner provided in the Indenture, subordinate and subject in right of
payment to the prior payment in full of all Senior Indebtedness of the Guarantor
(as defined in the Indenture). Senior Indebtedness 


                                      A-8
<PAGE>   76

of the Guarantor does not include (i) the Debentures, (ii) any obligation of the
Guarantor to any direct or indirect subsidiary, (iii) any accounts payable or
other liability to trade creditors arising in the ordinary course of business
(including guarantees thereof or instruments evidencing such liabilities), (iv)
any Indebtedness of the Guarantor (and any accrued and unpaid interest in
respect thereof) that by the express terms of the agreement or instrument
creating, evidencing or governing such Indebtedness is subordinate or junior in
any respect to any other Indebtedness or other obligation of the Guarantor, (v)
that portion of any Indebtedness which at the time of incurrence is incurred in
violation of the Indenture or (vi) any liability for federal, state, local or
other taxes owed or owing by the Guarantor. The Debenture on which this
Guarantee is endorsed is issued subject to the provisions of the Indenture with
respect to such subordination, and each holder of said Debenture, by accepting
the same, agrees to and shall be bound by such provisions of the Indenture.

         This Guarantee shall not be valid or become obligatory for any purpose
until the certificate of authentication on said Debenture shall have been
manually executed by the Trustee under the Indenture referred to in said
Debenture.

         IN WITNESS WHEREOF, Cincinnati Bell Inc. has caused this Guarantee to
be executed in its corporate name by the manual or facsimile signatures of its
President and its Chief Financial Officer, Treasurer or one of its Assistant
Treasurers.

                              CINCINNATI BELL INC.


         CINCINNATI BELL TELEPHONE COMPANY, an Ohio corporation (the "Company,"
which term includes any successor corporation under the Indenture referred to
below), for value received, hereby promises to pay to CEDE & CO., as the nominee
of The Depositary Trust Company ("DTC"), or registered assigns, the principal
sum of ONE HUNDRED FIFTY MILLION DOLLARS ($150,000,000) on December 1, 2028, and
to pay interest thereon semiannually in arrears on each June 1 and December 1
(each, an "Interest Payment Date"), commencing on June 1, 1999, and at maturity,
from November 30, 1998 or from the most recent Interest Payment Date to which
interest has been paid or duly provided for, at the rate of 6.30% per annum,
until the principal hereof becomes due and payable, and at such rate on any
overdue principal and (to the extent that the payment of such interest shall be
legally enforceable) on any overdue installment of interest.



                                     
<PAGE>   2


         The interest payable hereunder, and punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the Person in whose name this
Debenture is registered at the close of business on the regular record date for
such interest, which shall be the May 15 or November 15 (whether or not a
Business Day), as the case may be, next preceding such Interest Payment Date. If
and to the extent the Company shall default in the payment of the interest due,
if any, on such Interest Payment Date, such defaulted interest shall be paid to
the Persons in whose names the Debentures are registered at the close of
business on a special record date established for such payment by notice by or
on behalf of the Company to the Holders of the Securities not less than fifteen
days prior to such special record date, such special record date to be not less
than five days preceding the date of payment of such defaulted interest, all as
more fully provided in the Indenture.

         Interest shall be computed on the basis of a 360-day year consisting of
twelve 30-day months. Each payment of interest in respect of an Interest Payment
Date shall include interest accrued through the day prior to such Interest
Payment Date. If an Interest Payment Date shall not be a Business Day, then
payment of interest need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on such
Interest Payment Date, and no interest shall accrue for the period after such
date. "Business Day" with respect to the Debentures means a day that is neither
a legal holiday nor a day on which banking institutions are authorized by law to
close in New York, New York.

         Payment of the principal of (and premium, if any) and interest on this
Debenture shall be made at the office or agency of the Company in the Borough of
Manhattan, The City of New York, State of New York. Payment of the principal of
(and premium, if any) and interest on this Debenture shall be payable in
immediately available funds; provided, however, that payment of interest may be
made at the option of the Company by check mailed to the address of the person
entitled thereto at such address as it shall appear on the Debenture register.
Holders of over $5 million in principal amount of Debentures have the option of
receiving payment by wire by notifying the Paying Agent one business day prior
to the payment date. Payment of the principal of (and premium, if any) and
interest on this Debenture shall be made in such coin or currency of the United
States of America as at the time of payment shall be legal tender for the
payment of public and private debts. Interest payable on any Interest Payment
Date will be paid to DTC with respect to the portion of this Debenture held for
its account by CEDE & CO. for the purpose of permitting such party to credit the
interest received by it in respect of this Debenture to the accounts of the
beneficial owners hereof.

         Reference is hereby made to the further provisions of this Debenture
set forth on the reverse hereof and such further provisions shall for all
purposes have the same effect as though fully set forth at this place.


         This Debenture shall not be valid or become obligatory for any purpose
until the appropriate certificate of authentication hereon shall have been
executed by or on behalf of the Trustee under the Indenture referred to on the
reverse hereof.

                      GUARANTEED ON A SUBORDINATED BASIS BY

                              CINCINNATI BELL INC.


         This Debenture is one of a duly authorized issue of unsecured senior
debt securities of the Company known as the Company's Guaranteed 6.30%
Debentures due 2028 (herein called the "Debentures"), issued under an Indenture
dated as of November 30, 1998 (such Indenture as originally executed and
delivered and as hereafter supplemented or amended, together with the Board
Resolution setting forth certain terms of the Debentures adopted on September
18, 1998 and delivered to the Trustee by the Company pursuant to Section 2.07 of
such Indenture, being herein called the "Indenture") from the Company to The
Bank of New York, as trustee (herein called the "Trustee," which term includes
any other successor trustees under the Indenture), to which Indenture, all
indentures supplemental thereto and all Board Resolutions relating thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Guarantor, the
Trustee and the Holders of the Debentures and of the terms upon which the
Debentures are, and are to be, authenticated and delivered. The acceptance of
this Debenture shall be deemed to constitute the consent and agreement of the
Holders hereof to all of the terms and provisions of the Indenture. All
capitalized terms used in this Debenture which are not defined herein shall have
the meaning assigned to them in the Indenture.

         This Debenture shall be redeemable, as a whole or in part, at the
option of the Company, at any time or from time to time, at a redemption price
(the "Redemption Price") equal to the greater of (i) 100% of the principal
amount hereof and (ii) the sum of the present values of the Remaining Scheduled
Payments discounted to the Redemption Date on a semiannual basis (assuming a
360-day year consisting of twelve 30-day months) at the Treasury Rate plus
twenty basis points, plus, in the case of each of (i) and (ii), accrued interest
thereon to the Redemption Date. Notice of redemption shall be given by mail to
Debenture holders, not less than 30 days nor more than 60 days prior to the
Redemption Date, all as provided in the Indenture. On or prior to the Redemption
Date, the Company shall deposit with the Trustee or with a paying agent, if one
is so appointed in a manner not inconsistent with the Indenture, an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, the Debentures to
be redeemed on such date. In the event of redemption of this Debenture in part
only, a new Debenture or Debentures, of like tenor, for the unredeemed portion
hereof will be issued in the name of the holder hereof upon the surrender
hereof. Subject to the terms of the Indenture, on and after the Redemption Date,


                                    
<PAGE>   5

interest will cease to accrue on this Debenture (or any portion thereof) if so
called for redemption.

         "Comparable Treasury Issue" means the United States Treasury security
selected by the Independent Investment Banker as having a maturity comparable to
the remaining term of the Debentures to be redeemed that would be utilized, at
the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities with respect to comparable
maturity to the remaining term of the Debentures.

         "Comparable Treasury Price" means, with respect to any Redemption Date,
the average of three Reference Treasury Dealer Quotations obtained by the
Trustee for the Redemption Date.

         "Independent Investment Banker" means Salomon Smith Barney Inc., or its
successor.

         "Redemption Date," when used with respect to any Debenture to be
redeemed, in whole or in part, means the date fixed for such redemption pursuant
to the Indenture.

         "Reference Treasury Dealers" means Salomon Smith Barney Inc. or its
successor (so long as it, or its successor, continues to be a primary U.S.
government securities dealer) and any two other primary U.S. government
securities dealers chosen by the Company. If Salomon Smith Barney Inc. ceases to
be a primary U.S. government securities dealer, the Company shall appoint in its
place another nationally recognized investment banking firm that is a primary
U.S. government securities dealer.

         "Reference Treasury Dealer Quotations" means the average, as determined
by the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by three Reference Treasury Dealers at 3:30 p.m. New York
City time on the third Business Day preceding the Redemption Date.

         "Remaining Scheduled Payments" means, with respect to each Debenture to
be redeemed, the remaining scheduled payments of the principal thereof and
interest thereon that would be due after the related Redemption Date but for
such redemption; provided, however, that, if such Redemption Date is not an
Interest Payment Date with respect to such Debenture, the amount of the next
succeeding scheduled interest payment thereon will be reduced by the amount of
interest accrued thereon to such Redemption Date.

         "Treasury Rate" means, with respect to any Redemption Date, the rate
per annum equal to the semiannual equivalent yield to maturity (computed as of
the third Business Day immediately preceding such Redemption Date) of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such Redemption Date.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal hereof 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.

                                   
<PAGE>   6

         The Indenture contains provisions permitting the Company, the Guarantor
and the Trustee, with the consent of the holders of not less than 66 2/3% in
aggregate principal amount of the Debentures at the time outstanding, evidenced
as in the Indenture provided, to execute supplemental indentures adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or of any supplemental indenture or modifying in any manner the
rights of the holders of the Debentures; provided, however, that no such
supplemental indenture shall (i) extend the fixed maturity of any Debentures, 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 Debenture so affected, or
(ii) reduce the aforesaid percentage of Debentures, the consent of the holders
of which is required for any such supplemental indenture, without the consent of
the holders of all Debentures then outstanding. It is also provided in the
Indenture that the holders of a majority in aggregate principal amount of the
Debentures at the time outstanding may on behalf of the holders of all of the
Debentures waive any past default under the Indenture and its consequences,
except a default in the payment of the principal of (or premium, if any) or
interest on any of the Debentures. Any such consent or waiver by the holder of
any Debenture (unless revoked as provided in the Indenture) shall be conclusive
and binding upon such holder and upon all future holders and owners of such
Debenture and of any Debenture issued upon the transfer thereof or in exchange
or substitution therefor, irrespective of whether or not any notation of such
consent or waiver is made upon such Debenture or such other Debenture.

         No reference herein to the Indenture and no provision of this Debenture
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 Debenture at the places, at the respective times, at the rate
and in the coin or currency herein prescribed.

         The Debentures are issuable as registered Debentures without coupons in
denominations of $1,000 and any integral multiple of $1,000. At the office or
agency of the Company referred to on the face hereof and in the manner and
subject to the limitations provided in the Indenture, Debentures may be
exchanged without a service charge for a like aggregate principal amount of
Debentures of other authorized denominations.

         The Debentures may be represented by one or more global Debentures
deposited with The Depository Trust Company ("DTC") and registered in the name
of the nominee of DTC, with certain limited exceptions. So long as DTC or any
successor depositary or its nominee is the registered Holder of a global
Debenture, DTC, such depositary or such nominee, as the case may be, will be
considered to be the sole Holder of the Debentures for all purposes of the
Indenture. Except as provided below, an owner of a beneficial interest in a
global Debenture will not be entitled to have Debentures represented by such
global Debenture registered in such owner's name, will not receive or be
entitled to receive physical delivery of the Debentures in certificated form and
will not be considered the owner or Holder thereof under the Indenture. Each
person owning a beneficial interest in a global Debenture must rely on DTC's
procedures and, if such person is not a participant, on the procedures of the
participant through which such person owns its interest, to exercise any rights
of a Holder under the Indenture. If the Company requests any action of Holders
or if an owner of a beneficial interest in a global Debenture desires to take
any action that a Holder is entitled to take under the Indenture, DTC will
authorize the participants 


                                    
<PAGE>   7

holding the relevant beneficial interests to give or take such action, and such
participants will otherwise act upon the instructions of beneficial owners
holding through them.

         If at any time DTC notifies the Company that it is unwilling or unable
to continue as depositary for the global Debenture or Debentures or if at any
time DTC ceases to be a clearing agency registered under the Securities Exchange
Act of 1934, as amended, if so required by applicable law or regulation, the
Company shall appoint a successor depositary with respect to such global
Debenture or Debentures. If a successor depositary for such global Debenture or
Debentures is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such unwillingness, inability or
ineligibility or the Company, in its sole discretion, determines at any time
that all Outstanding Debentures (but not less than all) issued or issuable in
the form of one or more global Debentures shall no longer be represented by such
global Debentures, then the Company shall execute, and the Trustee shall
authenticate and deliver, definitive Debentures of like series, rank, tenor and
terms in definitive form in an aggregate principal amount equal to the principal
amount of such global Debenture or Debentures. If any beneficial owner of an
interest in a permanent global Debenture is otherwise entitled to exchange such
interest for Debentures of such series and of like tenor and principal amount of
another authorized form and denomination, as contemplated by the Indenture and
provided that any applicable notice provided in the permanent global Debenture
shall have been given, then without unnecessary delay, the Company shall
execute, and the Trustee shall authenticate and deliver, definitive Debentures
in aggregate principal amount equal to the principal amount of such beneficial
owner's interest in such permanent global Debenture.

         Upon the exchange of a Debenture in global form for Debentures in
certificated form, such Debenture in global form shall be canceled by the
Trustee. Debentures in certificated form issued in exchange for a Debenture in
global form shall be registered in such names and in such authorized
denominations as the depositary for such Debenture in global form, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Debentures to the Persons
in whose names such Debentures are so registered.

         None of the Company, the Trustee, any paying agent or the security
registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in this Debenture in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee, or any agent of the Company or the Trustee, from giving effect to any
written certification, proxy or other authorization furnished by any depositary,
as a Holder, with respect to this Debenture in global form or impair, as between
such depositary and owners of beneficial interests in such global Debenture, the
operation of customary practices governing the exercise of the rights of such
depositary (or its nominee) as Holder of such global Debenture.

         Upon due presentment for registration of transfer of this Debenture at
the above-mentioned office or agency of the Company, a new Debenture or
Debentures, of authorized denominations, for a like aggregate principal amount,
will be issued to the transferee as provided in the Indenture. No service charge
shall be made for any such transfer, but the 


                                    
<PAGE>   8

Company may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto.

         The Company, the Guarantor, the Trustee, the authenticating agent, any
paying agent and any Debenture registrar may deem and treat the holder hereof as
the absolute owner hereof (whether or not this Debenture shall be overdue and
notwithstanding any notation of ownership or other writing hereon) for the
purpose of receiving payment of or on account of the principal hereof (and
premium, if any) and, subject to the provisions on the face hereof, interest
hereon, and for all other purposes, and neither the Company nor the Trustee nor
the authenticating agent nor any paying agent nor any Debenture registrar shall
be affected by any notice to the contrary.

         No recourse shall be had for the payment of the principal of (or
premium, if any) or the interest on this Debenture or for any claim based
hereon, or otherwise in respect hereof, or based on or in respect of the
Indenture or any indenture supplemental thereto, against any incorporator,
shareholder (other than the Guarantor, to the extent of its obligations under
the Guarantee endorsed hereon), officer, director or employee, as such, past,
present or future, of the Company or of the Guarantor or of any successor
corporation, either directly or through the Company or the Guarantor or any
successor corporation, whether by virtue of any constitution, statute or rule of
law or by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of the consideration for
the issue hereof, expressly waived and released.

         This Debenture shall be deemed a contract made under the laws of the
State of New York and for all purposes shall be governed by and construed in
accordance with the laws of said State.

         FOR VALUE RECEIVED, Cincinnati Bell Inc., a corporation duly organized
and existing under the laws of the State of Ohio (herein called the
"Guarantor"), hereby guarantees to the holder of the Debenture upon which this
Guarantee is endorsed the payment of the principal of (and premium, if any) and
interest on said Debenture (including the costs and expenses of collection), in
accordance with the terms thereof and of the Indenture referred to therein. In
the event of any assignment of said Debenture, the Guarantor shall have all
defenses against the assignee which the Company or the Guarantor may have
against the assignor or any prior assignors. The Guarantor hereby covenants that
this Guarantee will not be discharged except by payment in full of the principal
of (and premium, if any) and interest on said Debenture (including the costs and
expenses of collection).

         The Guarantor shall be subrogated to all rights of the holder of said
Debenture 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 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 Debentures issued under said Indenture held
by others (including the costs and expenses of collection) shall have been paid
in full.

         The obligations evidenced by this Guarantee shall be, to the extent and
in the manner provided in the Indenture, subordinate and subject in right of
payment to the prior payment in full of all Senior Indebtedness of the Guarantor
(as defined in the Indenture). Senior 


                                      A-8
<PAGE>   9

Indebtedness of the Guarantor does not include (i) the Debentures, (ii) any
obligation of the Guarantor to any direct or indirect subsidiary, (iii) any
accounts payable or other liability to trade creditors arising in the ordinary
course of business (including guarantees thereof or instruments evidencing such
liabilities), (iv) any Indebtedness of the Guarantor (and any accrued and unpaid
interest in respect thereof) that by the express terms of the agreement or
instrument creating, evidencing or governing such Indebtedness is subordinate or
junior in any respect to any other Indebtedness or other obligation of the
Guarantor, (v) that portion of any Indebtedness which at the time of incurrence
is incurred in violation of the Indenture or (vi) any liability for federal,
state, local or other taxes owed or owing by the Guarantor. The Debenture on
which this Guarantee is endorsed is issued subject to the provisions of the
Indenture with respect to such subordination, and each holder of said Debenture,
by accepting the same, agrees to and shall be bound by such provisions of the
Indenture.

         This Guarantee shall not be valid or become obligatory for any purpose
until the certificate of authentication on said Debenture shall have been
manually executed by the Trustee under the Indenture referred to in said
Debenture.
