(the "Four Quarter Period") ending on or prior to the date of determination.

              For purposes of this definition, the aggregate outstanding
principal amount of Indebtedness of the Person and its Restricted Subsidiaries
for which such calculation is made shall be determined on a pro forma basis as
if the Indebtedness giving rise to the need to perform such calculation had been
incurred and the proceeds therefrom had been applied, and all other transactions
in respect of which such Indebtedness is being incurred has occurred, on the
last day of the Four Quarter Period. In addition to the foregoing, for purposes
of this definition, "Consolidated Cash Flow" shall be calculated on a pro forma
basis after giving effect to (i) the Transactions, (ii) the incurrence of the
Indebtedness of such Person and its Restricted Subsidiaries (and the application
of the proceeds therefrom) giving rise to the need to make such calculation and
any incurrence (and the application of the proceeds therefrom) or repayment of
other Indebtedness, other than the incurrence or repayment of Indebtedness
pursuant to working capital facilities, at any time subsequent to the beginning
of the Four Quarter Period and on or prior to the date of determination, as if
such incurrence (and the application of the proceeds thereof), or the repayment,
as the case may be, occurred on the first day of the Four Quarter Period, (iii)
any Asset Sales (including those excluded from the definition thereof by clause
(b), (c) or (d) of the definition thereof) or Asset Acquisitions (including,
without limitation, any Asset Acquisition giving rise to the need to make such
calculation as a result of such Person or one of its Subsidiaries (including any
Person that becomes a Restricted Subsidiary as a result of such Asset
Acquisition) incurring, assuming or otherwise becoming liable for Indebtedness)
or Asset Swaps at any time on or subsequent to the first day of the Four Quarter
Period and on or prior to the date of determination, as if such Asset Sale,
Asset Acquisition (including the incurrence, assumption or liability for any
such Indebtedness and also including any Consolidated Cash Flow associated with
such Asset Acquisition) or Asset Swap occurred on the first day of the Four
Quarter Period and (iv) cost savings resulting from employee termination,
facilities consolidations and closings, standardization of employee benefits and
compensation practices, consolidation of property, casualty and other insurance
coverage and policies, standardization of sales representation commissions and

statements under GAAP, Regulation S-X promulgated by the Commission or any other
regulation or 


<PAGE>   17

policy of the Commission), less the amount of any additional expenses that the
Company reasonably estimates would result from anticipated replacement of any
items constituting Cost Savings Measures in connection with such Asset
Acquisition or Asset Swap; provided, however, that both (A) such cost savings

consummation of the Asset Acquisition or Asset Swap and (B) with respect to each
Asset Acquisition or Asset Swap completed prior to the 90th day preceding such
date of determination, actions were commenced or initiated by the Company within
90 days of such Asset Acquisition or Asset Swap to effect the Cost Savings
Measures identified in such officer's certificate (regardless, however, of
whether the corresponding cost savings have been achieved). Furthermore, in
calculating "Consolidated Interest Expense" for purposes of the calculation of
"Consolidated Cash Flow," (i) interest on Indebtedness determined on a
fluctuating basis as of the date of determination (including Indebtedness
actually incurred on the date of the transaction giving rise to the need to
calculate the Leverage Ratio) and which will continue to be so determined
thereafter shall be deemed to have accrued at a fixed rate per annum equal to
the rate of interest on such Indebtedness as in effect on the date of
determination and (ii) notwithstanding (i) above, interest determined on a
fluctuating basis, to the extent such interest is covered by Interest Swap
Agreements, shall be deemed to accrue at the rate per annum resulting after
giving effect to the operation of such agreements.

of the cash or Cash Equivalents that is actually placed in escrow or segregated
and set aside by the transferor for such indemnification obligation shall not be
deemed to be Net Cash Proceeds until the escrow terminates or the transferor

principal, including payment at final maturity, in respect thereof, by (ii) the

                                   ARTICLE TWO

                                 THE SECURITIES


SECTION 2.01. Form and Dating.

              The Initial Securities and the Trustee's certificate of
authentication thereof shall be substantially in the form of Exhibit A hereto,
which is hereby incorporated in and expressly made a part of this Indenture. The
Exchange Securities and the Trustee's certificate of authentication thereof
shall be substantially in the form of Exhibit B hereto, which is hereby
incorporated in and expressly made a part of this Indenture. The Securities may
have notations, legends or endorsements (including the Subsidiary Guarantee)
required by law, stock exchange rule or usage. The Company and the Trustee shall
approve the form of the Securities and any notation, legend or endorsement
(including the Subsidiary Guarantee) on them. Each Security shall be dated the
date of its issuance and shall show the date of its authentication.

              Securities offered and sold in reliance on Rule 144A and
Securities offered and sold in reliance on Regulation S shall be issued
initially in the form of one or more Global Securities, substantially in the
form set forth in Exhibit A hereto, deposited with the Trustee, as custodian for
the Depository, duly executed by the Company and authenticated by the Trustee as
hereinafter provided and shall bear the legend set forth in Exhibit C hereto.
The aggregate principal amount of the Global Securities may from time to time be
increased or decreased by adjustments made on the records of the Trustee, as
custodian for the Depository, as hereinafter provided.

SECTION 2.02. Execution and Authentication.

              Two Officers or an Officer and an Assistant Secretary shall sign,
or one Officer shall sign and one Officer and an Officer and an Assistant
Secretary (each of whom shall, in each case, have been duly authorized by all
requisite corporate actions) shall attest to, the Securities for the Company by
manual or facsimile signature.


<PAGE>   26

                                      -19-

              If an Officer whose signature is on a Security or a Subsidiary
Guarantee, as the case may be, was an Officer at the time of such execution but
no longer holds that office at the time the Trustee authenticates the Security
or Subsidiary Guarantee, as the case may be, the Security or Subsidiary
Guarantee, as the case may be, shall be valid nevertheless.

              A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

              The Trustee shall authenticate (i) Initial Securities for original
issue in an aggregate principal amount not to exceed $300,000,000, (ii) Private
Exchange Securities from time to time only in exchange for a like principal
amount of Initial Securities and (iii) Unrestricted Securities from time to time
only in exchange for (A) a like principal amount of Initial Securities or (B) a
like principal amount of Private Exchange Securities, in each case upon a
written order of the Company in the form of an Officers' Certificate. Each such
written order shall specify the amount of Securities to be authenticated and the
date on which the Securities are to be authenticated, whether the Securities are
to be Initial Securities, Private Exchange Securities or Unrestricted Securities
and whether the Securities are to be issued as Physical Securities or Global
Securities and such other information as the Trustee may reasonably request. The
aggregate principal amount of Securities outstanding at any time may not exceed
$300,000,000, except as provided in Sections 2.07 and 2.08.

              Notwithstanding the foregoing, all Securities issued under this
Indenture shall vote and consent together on all matters (as to which any of
such Securities may vote or consent) as one class and no series of Securities
will have the right to vote or consent as a separate class on any matter.

              The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate Securities. Unless otherwise provided
in the appointment, an authenticating agent may authenticate Securities whenever
the Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent shall
have the same rights as an Agent to deal with the Company and Affiliates of the
Company.

              The Securities shall be issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof.

SECTION 2.03. Registrar and Paying Agent.

              The Company shall maintain an office or agency, which may be in
the Borough of Manhattan, The City of New York, where (a) Securities may be
presented or surrendered for registration of transfer or for exchange (the
"Registrar"), (b) Securities may be presented or surrendered for payment (the
"Paying Agent") and (c) notices and demands in respect of the Securities and
this Indenture may be served. The Registrar shall keep a register of the
Securities and of their transfer and exchange. The Company, upon notice to the
Trustee, may appoint one or more co-Registrars and one or more additional Paying
Agents. The term "Paying Agent" includes any additional Paying Agent. Except as
provided herein, the Company may act as Paying Agent, Registrar or co-Registrar.

              The Company shall enter into an appropriate agency agreement with
any Agent not a party to this Indenture, which shall incorporate the provisions
of the TIA. The agreement shall implement the provisions of this Indenture that
relate to such Agent. The Company shall notify the Trustee of the name and
address of any such Agent. If the Company fails to maintain a Registrar or
Paying Agent, or fails to give the 


<PAGE>   27

                                      -20-

foregoing notice, the Trustee shall act as such and shall be entitled to
appropriate compensation in accordance with Section 8.07.

              The Company initially appoints the Trustee as Registrar and Paying
Agent until such time as the Trustee has resigned or a successor has been
appointed.

SECTION 2.04. Paying Agent To Hold Assets in Trust.

              The Company shall require each Paying Agent other than the Trustee
to agree in writing that each Paying Agent shall hold in trust for the benefit
of Holders or the Trustee all assets held by the Paying Agent for the payment of
principal of, or interest on, the Securities, and shall notify the Trustee of
any Default by the Company in making any such payment. The Company at any time
may require a Paying Agent to distribute all assets held by it to the Trustee
and account for any assets disbursed and the Trustee may at any time during the
continuance of any payment Default, upon written request to a Paying Agent,
require such Paying Agent to distribute all assets held by it to the Trustee and
to account for any assets distributed. Upon distribution to the Trustee of all
assets that shall have been delivered by the Company to the Paying Agent (if
other than the Company), the Paying Agent shall have no further liability for
such assets. If the Company or any of their Affiliates acts as Paying Agent, it
shall, on or before each due date of the principal of or interest on the
Securities, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal or interest so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

SECTION 2.05. Holder Lists.

              The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders. If the Trustee is not the Registrar, the Company shall furnish to the
Trustee before each Interest Record Date and at such other times as the Trustee
may request in writing a list as of such date and in such form as the Trustee
may reasonably require of the names and addresses of Holders, which list may be
conclusively relied upon by the Trustee.

SECTION 2.06. Transfer and Exchange.

              Subject to the provisions of Sections 2.15 and 2.16, when
Securities are presented to the Registrar or a co-Registrar with a request to
register the transfer of such Securities or to exchange such Securities for an
equal principal amount of Securities of other authorized denominations of the
same series, the Registrar or co-Registrar shall register the transfer or make
the exchange as requested if its requirements for such transaction are met;
provided, however, that the Securities surrendered for transfer or exchange
shall be duly endorsed or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Registrar or co-Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing. To
permit registrations of transfers and exchanges, the Company shall execute and
the Trustee shall authenticate Securities at the Registrar's or co-Registrar's
written request. No service charge shall be made for any registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any transfer tax or similar governmental charge payable in connection
therewith (other than any such transfer taxes or other governmental charge
payable upon exchanges or transfers pursuant to Section 2.02, 2.10, 3.06, or
10.05). The Registrar or co-Registrar shall not be required to register the
transfer or exchange of any Security (i) during a period beginning at the
opening of business 15 days before the mailing of a notice of redemption of
Securities and ending at the close of business on the day of such mailing and
(ii) selected for redemption in whole or in part pursuant to Article Three
hereof, except the unredeemed portion of any Security being redeemed in part.


<PAGE>   28

                                      -21-

              Prior to the registration of any transfer by a Holder as provided
herein, the Company, the Trustee and any Agent of the Company shall treat the
person in whose name the Security is registered as the owner thereof for all
purposes whether or not the Security shall be overdue, and none of the Company,
the Trustee nor any such Agent shall be affected by notice to the contrary. Any
consent, waiver or actions of a Holder shall be binding upon any subsequent
Holders of such Security or a Security received upon transfer. Any Holder of a
beneficial interest in a Global Security shall, by acceptance of such beneficial
interest in a Global Security, agree that transfers of beneficial interests in
such Global Security may be effected only through a book-entry system maintained
by the Depository (or its agent), and that ownership of a beneficial interest in
a Global Security shall be required to be reflected in a book entry.

SECTION 2.07. Replacement Securities.

              If a mutilated Security is surrendered to the Trustee or if the
Holder of a Security claims that the Security has been lost, destroyed or
wrongfully taken, the Company shall issue and the Trustee shall authenticate a
replacement Security if the Trustee's requirements for replacement of Securities
are met. If required by the Company or the Trustee, such Holder must provide an
indemnity bond or other indemnity, sufficient in the judgment of the Company and
the Trustee, to protect the Company, the Trustee and any Agent from any loss
which any of them may suffer if a Security is replaced. The Company may charge
such Holder for their reasonable out-of-pocket expenses in replacing a Security,
including reasonable fees and expenses of counsel.

              Every replacement Security is an additional obligation of the
Company.

SECTION 2.08. Outstanding Securities.

              Securities outstanding at any time are all the Securities that
have been authenticated by the Trustee except those canceled by it, those
delivered to it for cancellation and those described in this Section 2.08 as not
outstanding. Subject to Section 2.09, a Security does not cease to be
outstanding because the Company or any Affiliates of the Company holds the
Security.

              If a Security is replaced pursuant to Section 2.07 (other than a
mutilated Security surrendered for replacement), it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Security
is held by a bona fide purchaser. A mutilated Security ceases to be outstanding
upon surrender of such Security and replacement thereof pursuant to Section
2.07.

              If on a Redemption Date or the Final Maturity Date the Paying
Agent holds money sufficient to pay all of the principal and interest due on the
Securities payable on that date, and is not prohibited from paying such money to
the Holders pursuant to the terms of this Indenture, then on and after that date
such Securities cease to be outstanding and interest on them ceases to accrue.

SECTION 2.09. Treasury Securities.

              In determining whether the Holders of the required principal
amount of Securities have concurred in any direction, waiver or consent,
Securities owned by the Company, the Guarantors or any of their respective
Affiliates shall be disregarded, except that, for the purposes of determining
whether the Trustee shall be protected in relying on any such direction, waiver
or consent, only Securities that a Trust Officer of the Trustee actually knows
are so owned shall be disregarded.

<PAGE>   29

                                      -22-

              The Company shall notify the Trustee, in writing, when the Company
or any of its respective Affiliates repurchases or otherwise acquires
Securities, of the aggregate principal amount of such Securities so repurchased
or otherwise acquired.

SECTION 2.10. Temporary Securities.

              Until definitive Securities are ready for delivery, the Company
may prepare and the Trustee shall authenticate temporary Securities upon receipt
of a written order of the Company in the form of an Officers' Certificate. The
Officers' Certificate shall specify the amount of temporary Securities to be
authenticated and the date on which the temporary Securities are to be
authenticated.

              Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate upon receipt of a written order
of the Company pursuant to Section 2.02 definitive Securities in exchange for
temporary Securities.

SECTION 2.11. Cancellation.

              The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Securities surrendered to them for transfer, exchange or payment. The
Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent,
and no one else, shall cancel, and at the written direction of the Company,
dispose of and deliver evidence of such disposal of all Securities surrendered
for transfer, exchange, payment or cancellation. Subject to Section 2.07, the
Company may not issue new Securities to replace Securities that they have paid
or delivered to the Trustee for cancellation. If the Company shall acquire any
of the Securities, such acquisition shall not operate as a redemption or
satisfaction of the Indebtedness represented by such Securities unless and until
the same are surrendered to the Trustee for cancellation pursuant to this
Section 2.11.

SECTION 2.12. Defaulted Interest.

              The Company shall pay interest on overdue principal from time to
time on demand at the rate of interest then borne by the Securities. The Company
shall, to the extent lawful, pay interest on overdue installments of interest
(without regard to any applicable grace periods) from time to time on demand at
the rate of interest then borne by the Securities.

              If the Company defaults in a payment of interest on the
Securities, it shall pay the defaulted interest, plus (to the extent lawful) any
interest payable on the defaulted interest to the Persons who are Holders on a
subsequent special record date, which date shall be the fifteenth day preceding
the date fixed by the Company for the payment of defaulted interest or the next
succeeding Business Day if such date is not a Business Day. At least 15 days
before the subsequent special record date, the Company shall mail to each
Holder, with a copy to the Trustee, a notice that states the subsequent special
record date, the payment date and the amount of defaulted interest, and interest
payable on such defaulted interest, if any, to be paid.

              Notwithstanding the foregoing, any interest which is paid prior to
the expiration of the 30-day period set forth in Section 6.01(a) shall be paid
to Holders as of the Interest Record Date for the Interest Payment Date for
which interest has not been paid.


<PAGE>   30

                                      -23-

SECTION 2.13. CUSIP Number.

              The Company in issuing the Securities will use a "CUSIP" number
and the Trustee shall use the CUSIP number in notices of redemption or exchange
as a convenience to Holders; provided, however, that any such notice may state
that no representation is made as to the correctness or accuracy of the CUSIP
number printed in the notice or on the Securities, and that reliance may be
placed only on the other identification numbers printed on the Securities. The
Company shall promptly notify the Trustee of any changes in CUSIP numbers.

SECTION 2.14. Deposit of Moneys.

              Prior to 11:00 a.m. New York City time on each Interest Payment
Date, Redemption Date, and the Final Maturity Date, the Company shall deposit
with the Paying Agent in immediately available funds money sufficient to make
cash payments, if any, due on such Interest Payment Date, Redemption Date or
Final Maturity Date, as the case may be, in a timely manner which permits the
Paying Agent to remit payment to the Holders on such Interest Payment Date,
Redemption Date or Final Maturity Date, as the case may be.

SECTION 2.15. Book-Entry Provisions for Global Securities.

              (a) The Global Securities initially shall (i) be registered in the
name of the Depository or the nominee of such Depository, (ii) be delivered to
the Trustee as custodian for such Depository and (iii) bear legends as set forth
in Exhibit C.

              Members of, or participants in, the Depository ("Participants")
shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depository, or the Trustee as its custodian, or
under the Global Security, and the Depository may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner of the
Global Security for all purposes whatsoever. 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 the Depository or impair, as between the
Depository and Participants, the operation of customary practices governing the
exercise of the rights of a Holder of any Security.

              (b) Transfers of Global Securities shall be limited to transfers
in whole, but not in part, to the Depository, its successors or their respective
nominees. Interests of beneficial owners in the Global Securities may be
transferred or exchanged for Physical Securities in accordance with the rules
and procedures of the Depository and the provisions of Section 2.16; provided,
however, that Physical Securities shall be transferred to all beneficial owners
in exchange for their beneficial interests in Global Securities if (i) the
Depository notifies the Company that it is unwilling or unable to continue as
Depository for any Global Security and a successor Depository is not appointed
by the Company within 90 days of such notice or (ii) an Event of Default has
occurred and is continuing and the Registrar has received a request from the
Depository to issue Physical Securities.

              (c) In connection with the transfer of Global Securities as an
entirety to beneficial owners pursuant to paragraph (b) of this Section 2.15,
the Global Securities shall be deemed to be surrendered to the Trustee for
cancellation, and the Company shall execute, and the Trustee shall upon written
instructions from the Company authenticate and deliver, to each beneficial owner
identified by the Depository in exchange for its beneficial interest in the
Global Securities, an equal aggregate principal amount of Physical Securities of
authorized denominations.


<PAGE>   31

                                      -24-

              (d) Any Physical Security constituting a Restricted Security
delivered in exchange for an interest in a Global Security pursuant to paragraph
(c) of this Section 2.15 shall, except as otherwise provided by Section 2.16,
bear the Private Placement Legend.

              (e) The Holder of any Global Security may grant proxies and
otherwise authorize any Person, including Participants and Persons that may hold
interests through Participants, to take any action which a Holder is entitled to
take under this Indenture or the Securities.

SECTION 2.16. Registration of Transfers and Exchanges.

              (a) Transfer and Exchange of Physical Securities. When Physical
Securities are presented to the Registrar or co-Registrar with a request:

                  (i) to register the transfer of the Physical Securities; or

                  (ii) to exchange such Physical Securities for an equal 
      principal amount of Physical Securities of other authorized denominations,

the Registrar or co-Registrar shall register the transfer or make the exchange
as requested if the requirements under this Indenture as set forth in this
Section 2.16 for such transactions are met; provided, however, that the Physical
Securities presented or surrendered for registration of transfer or exchange:

              (I) shall be duly endorsed or accompanied by a written instrument 
         of transfer in form satisfactory to the Registrar or co-Registrar, duly
         executed by the Holder thereof or his attorney duly authorized in 
         writing; and

              (II) in the case of Physical Securities the offer and sale of
         which have not been registered under the Securities Act, such Physical
         Securities shall be accompanied, in the sole discretion of the Company,
         by the following additional information and documents, as applicable:

              (A)    if such Physical Security is being delivered to the
                     Registrar or co-Registrar by a Holder for registration in
                     the name of such Holder, without transfer, a certification
                     from such Holder to that effect (substantially in the form
                     of Exhibit D hereto); or

              (B)    if such Physical Security is being transferred to a QIB in
                     accordance with Rule 144A, a certification to that effect
                     (substantially in the form of Exhibit D hereto); or

              (C)    if such Physical Security is being transferred to an
                     Institutional Accredited Investor, delivery of a
                     certification to that effect (substantially in the form of
                     Exhibit D hereto) and a transferee letter of representation
                     (substantially in the form of Exhibit E hereto) and, at the
                     option of the Company, an Opinion of Counsel reasonably
                     satisfactory to the Company to the effect that such
                     transfer is in compliance with the Securities Act; or

              (D)    if such Physical Security is being transferred in reliance
                     on Rule 144 under the Securities Act, delivery of a
                     certification to that effect (substantially in the form of
                     Exhibit D hereto) and, at the option of the Company, an
                     Opinion of Counsel reasonably satisfactory to the Company
                     to the effect that such transfer is in compliance with the
                     Securities Act; or

                                      -25-

              (E)    if such Physical Security is being transferred in reliance
                     on Regulation S, delivery of a certification to that effect
                     (substantially in the form of Exhibit D hereto) and a
                     transferor certificate for Regulation S transfers
                     (substantially in the form of Exhibit F hereto) and, at the
                     option of the Company, an Opinion of Counsel reasonably
                     satisfactory to the Company to the effect that such
                     transfer is in compliance with the Securities Act; or

              (F)    if such Physical Security is being transferred in reliance
                     on another exemption from the registration requirements of
                     the Securities Act, a certification to that effect
                     (substantially in the form of Exhibit D hereto) and, at the
                     option of the Company, an Opinion of Counsel reasonably
                     acceptable to the Company to the effect that such transfer
                     is in compliance with the Securities Act.

              (b) Restrictions on Transfer of a Physical Security for a
Beneficial Interest in a Global Security. A Physical Security the offer and sale
of which has not been registered under the Securities Act may not be exchanged
for a beneficial interest in a Global Security except upon satisfaction of the
requirements set forth below. Upon receipt by the Registrar or co-Registrar of a
Physical Security, duly endorsed or accompanied by appropriate instruments of
transfer, in form satisfactory to the Registrar or co-Registrar, together with:

              (A)    certification, substantially in the form of Exhibit D
                     hereto, that such Physical Security is being transferred
                     (I) to a QIB, (II) to an Institutional Accredited Investor
                     or (III) in an offshore transaction in reliance on
                     Regulation S and, with respect to (II) or (III), at the
                     option of the Company, an Opinion of Counsel reasonably
                     acceptable to the Company to the effect that such transfer
                     is in compliance with the Securities Act; and

              (B)    written instructions directing the Registrar or
                     co-Registrar to make, or to direct the Depository to make,
                     an endorsement on the applicable Global Security to reflect
                     an increase in the aggregate amount of the Securities
                     represented by the Global Security,

then the Registrar or co-Registrar shall cancel such Physical Security and
cause, or direct the Depository to cause, in accordance with the standing
instructions and procedures existing between the Depository and the Registrar or
co-Registrar, the principal amount of Securities represented by the applicable
Global Security to be increased accordingly. If no 144A Global Security, IAI
Global Security or Regulation S Global Security, as the case may be, is then
outstanding, the Company shall, unless either of the events in the proviso to
Section 2.15(b) have occurred and are continuing, issue and the Trustee shall,
upon written instructions from the Company in accordance with Section 2.02,
authenticate such a Global Security in the appropriate principal amount.

              (c) Transfer and Exchange of Global Securities. The transfer and
exchange of Global Securities or beneficial interests therein shall be effected
through the Depository in accordance with this Indenture (including the
restrictions on transfer set forth herein) and the procedures of the Depository
therefor. Upon receipt by the Registrar or Co-Registrar of written instructions,
or such other instruction as is customary for the Depository, from the
Depository or its nominee, requesting the registration of transfer of an
interest in a 144A Global Security, an IAI Global Security or a Regulation S
Global Security, as the case may be, to another type of Global Security,
together with the applicable Global Securities (or, if the applicable type of
Global Security required to represent the interest as requested to be obtained
is not then outstanding, only the Global Security 


<PAGE>   33

                                      -26-

representing the interest being transferred), the Registrar or Co-Registrar
shall reflect on its books and records (and the applicable Global Security) the
applicable increase and decrease of the principal amount of Securities
represented by such types of Global Securities, giving effect to such transfer.
If the applicable type of Global Security required to represent the interest as
requested to be obtained is not outstanding at the time of such request, the
Company shall issue and the Trustee shall, upon written instructions from the
Company in accordance with Section 2.02, authenticate a new Global Security of
such type in principal amount equal to the principal amount of the interest
requested to be transferred.

              (d) Transfer of a Beneficial Interest in a Global Security for a
Physical Security.

                   (i) Any Person having a beneficial interest in a Global
         Security may upon request exchange such beneficial interest for a
         Physical Security; provided, however, that prior to the Registration, a
         transferee that is a QIB or Institutional Accredited Investor may not
         exchange a beneficial interest in Global Security for a Physical
         Security. Upon receipt by the Registrar or co-Registrar of written
         instructions, or such other form of instructions as is customary for
         the Depository, from the Depository or its nominee on behalf of any
         Person having a beneficial interest in a Global Security and upon
         receipt by the Trustee of a written order or such other form of
         instructions as is customary for the Depository or the Person
         designated by the Depository as having such a beneficial interest
         containing registration instructions and, in the case of any such
         transfer or exchange of a beneficial interest in Securities the offer
         and sale of which have not been registered under the Securities Act,
         the following additional information and documents:

              (A)    if such beneficial interest is being transferred in
                     reliance on Rule 144 under the Securities Act, delivery of
                     a certification to that effect (substantially in the form
                     of Exhibit D hereto) and, at the option of the Company, an
                     Opinion of Counsel reasonably satisfactory to the Company
                     to the effect that such transfer is in compliance with the
                     Securities Act; or

              (B)    if such beneficial interest is being transferred in
                     reliance on another exemption from the registration
                     requirements of the Securities Act, a certification to that
                     effect (substantially in the form of Exhibit D hereto) and,
                     at the option of the Company, an Opinion of Counsel
                     reasonably satisfactory to the Company to the effect that
                     such transfer is in compliance with the Securities Act,

         then the Registrar or co-Registrar will cause, in accordance with the
         standing instructions and procedures existing between the Depository
         and the Registrar or co-Registrar, the aggregate principal amount of
         the applicable Global Security to be reduced and, following such
         reduction, the Company will execute and, upon receipt of an
         authentication order in the form of an Officers' Certificate in
         accordance with Section 2.02, the Trustee will authenticate and deliver
         to the transferee a Physical Security in the appropriate principal
         amount.

                  (ii) Securities issued in exchange for a beneficial interest
         in a Global Security pursuant to this Section 2.16(d) shall be
         registered in such names and in such authorized denominations as the
         Depository, pursuant to instructions from its direct or indirect
         participants or otherwise, shall instruct the Registrar or co-Registrar
         in writing. The Registrar or co-Registrar shall deliver such Physical
         Securities to the Persons in whose names such Physical Securities are
         so registered.

              (e) Restrictions on Transfer and Exchange of Global Securities.
Notwithstanding any other provisions of this Indenture, a Global Security may
not be transferred as a whole except by the Depository to a 


<PAGE>   34

                                      -27-

nominee of the Depository or by a nominee of the Depository to the Depository or
another nominee of the Depository or by the Depository or any such nominee to a
successor Depository or a nominee of such successor Depository.

              (f) Private Placement Legend. Upon the transfer, exchange or
replacement of Securities not bearing the Private Placement Legend, the
Registrar or co-Registrar shall deliver Securities that do not bear the Private
Placement Legend. Upon the transfer, exchange or replacement of Securities
bearing the Private Placement Legend, the Registrar or co-Registrar shall
deliver only Securities that bear the Private Placement Legend unless, and the
Trustee is hereby authorized to deliver Securities without the Private Placement
Legend if, (i) there is delivered to the Trustee an Opinion of Counsel
reasonably satisfactory to the Company and the Trustee to the effect that
neither such legend nor the related restrictions on transfer are required in
order to maintain compliance with the provisions of the Securities Act;(ii) such
Security has been sold pursuant to an effective registration statement under the
Securities Act (including pursuant to a Registration); or (iii) the date of such
transfer, exchange or replacement is two years after the later of (x) the Issue
Date and (y) the last date that the Company or any affiliate (as defined in Rule
144 under the Securities Act) of the Company was the owner of such Securities
(or any predecessor thereto).

              (g) General. By its acceptance of any Security bearing the Private
Placement Legend, each Holder of such a Security acknowledges the restrictions
on transfer of such Security set forth in this Indenture and in the Private
Placement Legend and agrees that it will transfer such Security only as provided
in this Indenture.

              The Trustee shall have no obligation or duty to monitor, determine
or inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Security (including any transfers between or among Participants or
beneficial owners of interest in any Global Security) other than to require
delivery of such certificates and other documentation or evidence as are
expressly required by, and to do so if and when expressly required by the terms
of, this Indenture, and to examine the same to determine substantial compliance
as to form with the express requirements hereof.

              The Registrar shall retain copies of all letters, notices and
other written communications received pursuant to Section 2.15 or this Section
2.16. The Company shall have the right to inspect and make copies of all such
letters, notices or other written communications at any reasonable time upon the
giving of reasonable written notice to the Registrar.


                                  ARTICLE THREE

                                   REDEMPTION


SECTION 3.01. Notices to Trustee.

              If the Company elects to redeem Securities pursuant to paragraph 5
of the Securities at the applicable redemption price set forth thereon, it shall
notify the Trustee in writing of the Redemption Date and the principal amount of
Securities to be redeemed. The Company shall give such notice to the Trustee at
least 45 days before the Redemption Date (unless a shorter notice shall be
agreed to by the Trustee in writing), to-


<PAGE>   35

                                      -28-

gether with an Officers' Certificate stating that such redemption will comply
with the conditions contained herein.

SECTION 3.02. Selection of Securities To Be Redeemed.

              If less than all of the Securities are to be redeemed pursuant to
paragraph 5 of the Securities, the Trustee shall select the Securities to be
redeemed in compliance with the requirements of the national securities
exchange, if any, on which the Securities are listed or, in the absence of such
requirements or if the Securities are not then listed on a national securities
exchange, on a pro rata basis, by lot or in such other manner as may be required
pursuant to this Indenture or otherwise as the Trustee shall deem fair and
appropriate. Selection of the Securities to be redeemed pursuant to paragraph
5(b) of the Securities shall be made by the Trustee only on a pro rata basis or
on as nearly a pro rata basis as is practicable (subject to the procedures of
the Depository) based on the aggregate principal amount of Securities held by
each Holder. The Trustee shall make the selection from the Securities then
outstanding, subject to redemption and not previously called for redemption.

              The Trustee may select for redemption pursuant to paragraph 5 of
the Securities portions of the principal amount of Securities that have
denominations equal to or larger than $1,000 principal amount. Securities and
portions of them the Trustee so selects shall be in amounts of $1,000 principal
amount or integral multiples thereof. Provisions of this Indenture that apply to
Securities called for redemption also apply to portions of Securities called for
redemption.

SECTION 3.03. Notice of Redemption.

              At least 30 days but not more than 60 days before a Redemption
Date, the Company shall mail a notice of redemption by first-class mail to each
Holder whose Securities are to be redeemed at such Holder's registered address;
provided, however, that notice of a redemption pursuant to paragraph 5(b) of the
Securities shall be mailed to each Holder whose Securities are to be redeemed no
later than 60 days after the date of the closing of the relevant Equity Offering
of the Company.

              Each notice of redemption shall identify the Securities to be
redeemed (including the CUSIP number thereon) and shall state:

         (1)      the Redemption Date;

         (2)      the redemption price;

         (3) the name and address of the Paying Agent to which the Securities
     are to be surrendered for redemption;

         (4) that Securities called for redemption must be surrendered to the
     Paying Agent to collect the redemption price;

         (5) that, as long as the Company has deposited with the Paying Agent
     funds in satisfaction of the applicable redemption price pursuant to this
     Indenture, interest on Securities called for redemption ceases to accrue on
     and after the Redemption Date and the only remaining right of the Holders
     is to receive payment of the redemption price upon surrender to the Paying
     Agent;

<PAGE>   36

                                      -29-

         (6) in the case of any redemption pursuant to paragraph 5 of the
     Securities, if any Security is being redeemed in part, the portion of the
     principal amount of such Security to be redeemed and that, after the
     Redemption Date, upon surrender of such Security, a new Security or
     Securities in principal amount equal to the unredeemed portion thereof will
     be issued;

         (7) the subparagraph of the Securities pursuant to which such
     redemption is being made; and

         (8) that no representation is made as to the accuracy of the CUSIP
     number listed in such notice or printed on such Security.

              At the Company's request, the Trustee shall give the notice of
redemption on behalf of the Company, in the Company's name and at the Company's
expense.

SECTION 3.04. Effect of Notice of Redemption.

              Once a notice of redemption is mailed, Securities called for
redemption become due and payable on the Redemption Date and at the redemption
price. Upon surrender to the Paying Agent, such Securities shall be paid at the
redemption price, plus accrued interest thereon, if any, to the Redemption Date,
but interest installments whose maturity is on or prior to such Redemption Date
shall be payable to the Holders of record at the close of business on the
relevant Interest Record Date.

SECTION 3.05. Deposit of Redemption Price.

              At least one Business Day before the Redemption Date, the Company
shall deposit with the Paying Agent (or if the Company is its own Paying Agent,
it shall, on or before the Redemption Date, segregate and hold in trust) money
sufficient to pay the redemption price of and accrued interest, if any, on all
Securities to be redeemed on that date other than Securities or portions thereof
called for redemption on that date which have been delivered by the Company to
the Trustee for cancellation.

              If any Security surrendered for redemption in the manner provided
in the Securities shall not be so paid on the Redemption Date due to the failure
of the Company to deposit with the Paying Agent money sufficient to pay the
redemption price thereof, the principal and accrued and unpaid interest, if any,
thereon shall, until paid or duly provided for, bear interest as provided in
Sections 2.12 and 4.01 with respect to any payment default.

SECTION 3.06. Securities Redeemed in Part.

              Upon surrender of a Security that is redeemed in part, the Trustee
shall authenticate for the Holder a new Security equal in principal amount to
the unredeemed portion of the Security surrendered.

                                    COVENANTS


SECTION 4.01. Payment of Securities.

              The Company shall pay the principal of and interest on the
Securities in the manner provided in the Securities and the Registration Rights
Agreement. An installment of principal or interest shall be considered paid on
the date due if the Trustee or Paying Agent (other than the Company or any
Affiliates of the Company) holds on that date money designated for and
sufficient to pay the installment in full and is not prohibited from paying such
money to the Holders of the Securities pursuant to the terms of this Indenture.

              The Company shall pay cash interest on overdue principal at the
same rate per annum borne by the Securities. The Company shall pay cash interest
on overdue installments of interest at the same rate per annum borne by the
Securities, to the extent lawful, as provided in Section 2.12.

SECTION 4.02. Maintenance of Office or Agency.

              The Company shall give prompt written notice to the Trustee of the
location, and any change in the location, of any office or agency required by
Section 2.03. If at any time the Company shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the address of the Trustee set forth in Section 13. The Company hereby
initially designates the Trustee at its address set forth in Section 13.02 as
its office or agency in The Borough of Manhattan, The City of New York, for such
purposes.

SECTION 4.03. Limitation on Transactions with Affiliates.

              The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, enter into or permit to exist any
transaction (including, without limitation, the purchase, sale, lease,
contribution or exchange of any property or the rendering of any service) with
or for the benefit of any of its Affiliates (other than transactions between the
Company and a Restricted Subsidiary of the Company or among Restricted
Subsidiaries of the Company) (an "Affiliate Transaction"), other than Affiliate
Transactions on terms that are no less favorable than those that might
reasonably have been obtained in a comparable transaction on an arm's-length
basis from a person that is not an Affiliate; provided, however, that for a
transaction or series of related transactions involving value of $5,000,000 or
more, such determination shall be made in good faith by a majority of members of
the Board of Directors of the Company and by a majority of the disinterested
members of the Board of Directors of the Company, if any; provided, further,
that for a transaction or series of related transactions involving value of
$15,000,000 or more, the Board of Directors of the Company has received an
opinion from an independent investment banking firm of nationally recognized
standing that such Affiliate Transaction is fair, from a financial point of
view, to the Company or such Restricted Subsidiary. The foregoing restrictions
shall not apply to (1) reasonable and customary directors' fees, indemnification
and similar arrangements and payments thereunder; (2) any obligations of the
Company under any employment agreement, noncompetition or confidentiality
agreement with any officer of the Company, as in effect on the Issue Date
(provided that each amendment of any of the foregoing agreements shall be
subject to the limitations of this covenant); (3) any Restricted Payment
permitted to be made pursuant Section 4.10; (4) any issuance of securities, or
other payments, awards or grants in cash, securities or otherwise pursuant to,
or the funding of, employment arrangements, stock options and stock ownership
plans approved by the Board of Directors of the

Company; (5) loans or advances to employees in the ordinary course of business
of the Company or any of its Restricted Subsidiaries consistent with past
practices; (6) payments made in connection with the Transactions and the Grand
Rapids Acquisition, including, without limitation, fees to Hicks Muse, as
described in the Offering Memorandum; and (7) payments by the Company to Hicks
Muse Partners in accordance with the terms of the Financial Advisory Agreement
and the Monitoring and Oversight Agreement.

SECTION 4.04. Limitation on Incurrence of Additional Indebtedness and Issuance
              of Capital Stock.

              (a) The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, assume,
guarantee or otherwise become directly or indirectly liable, contingently or
otherwise, with respect to (collectively, "incur") any Indebtedness (other than
Permitted Indebtedness) and the Company shall not issue any Disqualified Capital
Stock and its Restricted Subsidiaries shall not issue any Preferred Stock
(except Preferred Stock issued to the Company or a Restricted Subsidiary of the
Company so long as it is so held); provided, however, that the Company and its
Restricted Subsidiaries that are Guarantors may incur Indebtedness or issue
shares of such Capital Stock if, in either case, the Company's Leverage Ratio at
the time of incurrence of such Indebtedness or the issuance of such Capital
Stock, as the case may be, after giving pro forma effect to such incurrence or
issuance as of such date and to the use of proceeds therefrom is less than 7.0
to 1.

              (b) The Company shall not incur or suffer to exist, or permit any
of its Restricted Subsidiaries to incur or suffer to exist, any Obligations with
respect to an Unrestricted Subsidiary that would violate the provisions set
forth in the definition of Unrestricted Subsidiary.

SECTION 4.05. Limitation on Layering.

              The Company shall not incur any Indebtedness if such Indebtedness
is subordinate or junior in ranking in any respect to any Senior Indebtedness
unless such Indebtedness is Senior Subordinated Indebtedness or is contractually
subordinated in right of payment to all Senior Subordinated Indebtedness
(including the Securities).

SECTION 4.06. Payments for Consents.

              Neither the Company nor any of its Subsidiaries shall, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any Holder of any Securities for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture or the Securities unless such consideration is offered to be
paid or is paid to all Holders of the Securities that consent, waive or agree to
amend in the time frame set forth in the solicitation documents relating to such
consent, waiver or agreement.

SECTION 4.07. Limitation on Investment Company Status.

              The Company and its Subsidiaries shall not take any action, or
otherwise permit to exist any circumstance, that would require the Company to
register as an "investment company" under the Investment Company Act of 1940, as
amended.

SECTION 4.08. Limitation on Asset Sales.

              The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless (i) the Company or the
applicable Restricted Subsidiary, as the case may be, receives consideration at
the time of such Asset Sale at least equal to the fair market value of the
assets sold or otherwise disposed of (as determined in good faith by management
of the Company or, if such Asset Sale involves consideration in excess of
$10,000,000, by the board of directors of the Company, as evidenced by a board
resolution), (ii) at least 75% of the consideration received by the Company or
such Restricted Subsidiary, as the case may be, from such Asset Sale is in the
form of cash or Cash Equivalents and is received at the time of such disposition
and (iii) upon the consummation of an Asset Sale, the Company applies, or causes
such Restricted Subsidiary to apply, such Net Cash Proceeds within 180 days of
receipt thereof either (A) to repay any Senior Indebtedness of the Company or
any Indebtedness of a Restricted Subsidiary of the Company (and, to the extent
such Senior Indebtedness relates to principal under a revolving credit or
similar facility, to obtain a corresponding reduction in the commitments
thereunder, except that the Company may temporarily repay Senior Indebtedness
using the Net Cash Proceeds from such Asset Sale and thereafter use such funds
to reinvest pursuant to clause (B) below within the period set forth therein
without having to obtain a corresponding reduction in the commitments
thereunder), (B) to reinvest, or to be contractually committed to reinvest
pursuant to a binding agreement, in Productive Assets and, in the latter case,
to have so reinvested within 360 days of the date of receipt of such Net Cash
Proceeds or (C) to purchase Securities and other Senior Subordinated
Indebtedness, pro rata tendered to the Company for purchase at a price equal to
100% of the principal amount thereof (or the accreted value of such other Senior
Subordinated Indebtedness, if such other Senior Subordinated Indebtedness is
issued at a discount) plus accrued interest thereon, if any, to the date of
purchase pursuant to an offer to purchase made by the Company as set forth below
(a "Net Proceeds Offer"); provided, however, that the Company may defer making a
Net Proceeds Offer until the aggregate Net Cash Proceeds from Asset Sales not
otherwise applied in accordance with this covenant equal or exceed $15,000,000.

              Subject to the deferral right set forth in the final proviso of
the preceding paragraph, each notice of a Net Proceeds Offer shall be mailed, by
first-class mail, to Holders not more than 180 days after the relevant Asset
Sale or, in the event the Company or a Restricted Subsidiary has entered into a
binding agreement as provided in (B) above, within 180 days following the
termination of such agreement but in no event later than 360 days after the
relevant Asset Sale. Such notice shall specify, among other things, the purchase
date (which shall be no earlier than 30 days nor later than 45 days from the
date such notice is mailed, except as otherwise required by law) and shall
otherwise comply with the procedures set forth in this Indenture. Upon receiving
notice of the Net Proceeds Offer, Holders may elect to tender their Securities
in whole or in part in integral multiples of $1,000. To the extent Holders
properly tender Securities in an amount which, together with all other Senior
Subordinated Indebtedness so tendered, exceeds the Net Proceeds Offer,
Securities and other Senior Subordinated Indebtedness of tendering Holders shall
be repurchased on a pro rata basis (based upon the aggregate principal amount
tendered, or, if applicable, the aggregate accreted value tendered). To the
extent that the aggregate principal amount of Securities tendered pursuant to
any Net Proceeds Offer, which, together with the aggregate principal amount or
aggregate accreted value, as the case may be, of all other Senior Subordinated
Indebtedness so tendered, is less than the amount of Net Cash Proceeds subject
to such Net Proceeds Offer, the Company may use any remaining portion of such
Net Cash Proceeds not required to fund the repurchase of tendered Securities and
other Senior Subordinated Indebtedness for any purposes not otherwise prohibited
by this Indenture. Upon the consummation of any Net Proceeds Offer, the amount
of Net Cash Proceeds subject to any future Net Proceeds Offer from the Asset
Sales giving rise to such Net Cash Proceeds shall be deemed to be zero.

              The Company shall comply with the requirements of Rule 14e-1 under
the Exchange Act to the extent applicable in connection with the repurchase of
Securities pursuant to a Net Proceeds Offer.

SECTION 4.09. Limitation on Asset Swaps.

              The Company shall not, and shall not permit any Restricted
Subsidiary to, engage in any Asset Swap unless: (i) at the time of entering into
such Asset Swap, and immediately after giving effect to such Asset Swap, no
Default or Event of Default shall have occurred and be continuing, (ii) in the
event such Asset Swap involves an aggregate amount in excess of $10,000,000, the
terms of such Asset Swap have been approved by a majority of the members of the
Board of Directors of the Company and (iii) in the event such Asset Swap
involves an aggregate amount in excess of $50,000,000, the Company has received
a written opinion from an independent investment banking firm of nationally
recognized standing that such Asset Swap is fair to the Company or such
Restricted Subsidiary, as the case may be, from a financial point of view.

SECTION 4.10. Limitation on Restricted Payments.

              (a) The Company shall not, and shall not cause or permit any of
its Restricted Subsidiaries, to, directly or indirectly, make any Restricted
Payment if at the time of such Restricted Payment and immediately after giving
effect thereto:

                   (i)   a Default or Event of Default shall have occurred and
         be continuing; or

                  (ii)   the Company is not able to incur $1.00 of additional
         Indebtedness (other than Permitted Indebtedness) in compliance with
         Section 4.04; or

                 (iii)   the aggregate amount of Restricted Payments made
         subsequent to the Issue Date (the amount expended for such purposes, if
         other than in cash, being the fair market value of such property as
         determined by the Board of Directors of the Company in good faith)
         exceeds the sum of (a)(x) 100% of the aggregate Consolidated Cash Flow
         of the Company (or, in the event such Consolidated Cash Flow shall be a
         deficit, minus 100% of such deficit) accrued subsequent to the Issue
         Date to the most recent date for which financial information is
         available to the Company, taken as one accounting period, less (y) 1.4
         times Consolidated Interest Expense for the same period, plus (b) 100%
         of the aggregate net proceeds, including the fair market value of
         property other than cash as determined by the Board of Directors of the

         Company from any Person (other than a Restricted Subsidiary of the
         Company) from the issuance and sale subsequent to the Issue Date of
         Qualified Capital Stock of the Company (excluding (i) any net proceeds
         from issuances and sales financed directly or indirectly using funds
         borrowed from the Company or any Restricted Subsidiary of the Company,
         until and to the extent such borrowing is repaid, but including the
         proceeds from the issuance and sale of any securities convertible into
         or exchangeable for Qualified Capital Stock to the extent such
         securities are so converted or exchanged and including any additional
         proceeds received by the Company upon such conversion or exchange and
         (ii) any net proceeds received from issuances and sales that are used
         to consummate a transaction described in clause (2) of paragraph (b)
         below), plus (c) without duplication of any amount included in clause
         (iii)(b) above, 100% of the aggregate net proceeds, including the fair
         market value of property other than cash (valued as provided in clause
         (iii)(b) above), received by the Company as a capital contribution
         subsequent to the Issue Date, plus (d) the amount equal to the net
         reduction in Investments (other than Permitted Investments) made by the
         Company or any of its Restricted Subsidiaries in any Person resulting
         from, and without duplication, (i) repurchases or redemptions of such
         Investments by such Person, proceeds realized upon the sale of such
         Investment to an unaffiliated purchaser and repayments of

         Company or any Restricted Subsidiary of the Company or (ii) the
         redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries
         (valued in each case as provided in the definition of "Investment") not
         to exceed, in the case of any Restricted Subsidiary, the amount of
         Investments previously made by the Company or any of its Restricted
         Subsidiaries in such Unrestricted Subsidiary, which amount was included
         in the calculation of Restricted Payments; provided, however, that no
         amount shall be included under this clause (d) to the extent it is
         already included in Consolidated Cash Flow, plus (e) the aggregate net
         cash proceeds received by a Person in consideration for the issuance of
         such Person's Capital Stock (other than Disqualified Capital Stock)
         that are held by such Person at the time such Person is merged with and
         into the Company in accordance with Section 5.01 subsequent to the
         Issue Date; provided, however, that concurrently with or immediately
         following such merger the Company uses an amount equal to such net cash
         proceeds to redeem or repurchase the Company's Capital Stock, plus (f)
         $15,000,000.


              (b) Notwithstanding the foregoing, these provisions will not
prohibit: (1) the payment of any dividend or the making of any distribution
within 60 days after the date of its declaration if such dividend or
distribution would have been permitted on the date of declaration; (2) the
purchase, redemption or other acquisition or retirement of any Capital Stock of
the Company or any warrants, options or other rights to acquire shares of any
class of such Capital Stock either (x) solely in exchange for shares of

(y) through the application of the net proceeds of a substantially concurrent
sale for cash (other than to a Restricted Subsidiary of the Company) of shares
of Qualified Capital Stock or warrants, options or other rights to acquire
Qualified Capital Stock or (z) in the case of Disqualified Capital Stock, solely
in exchange for, or through the application of the net proceeds of a
substantially concurrent sale for cash (other than to a Restricted Subsidiary of
the Company) of, Disqualified Capital Stock; (3) payments made pursuant to any
merger, consolidation or sale of assets effected in accordance with Section
5.01; provided, however, that no such payment may be made pursuant to this
clause (3) unless, after giving effect to such transaction (and the incurrence
of any Indebtedness in connection therewith and the use of the proceeds
thereof), the Company would be able to incur $1.00 of additional Indebtedness
(other than Permitted Indebtedness) in compliance with Section 4.04 such that
after incurring that $1.00 of additional Indebtedness, the Leverage Ratio would
be less than 6.0 to 1; (4) payments to enable the Company or a Holding Company
(as hereinafter defined) to pay dividends on its Capital Stock (other than
Disqualified Capital Stock) after the first Public Equity Offering in an annual
amount not to exceed 6.0% of the gross proceeds (before deducting underwriting
discounts and commissions and other fees and expenses of the offering) received
from shares of Capital Stock (other than Disqualified Capital Stock) sold for
the account of the issuer thereof (and not for the account of any stockholder)
in such initial Public Equity Offering; (5) payments by the Company to fund the
payment by any company as to which the Company is, directly or indirectly, a
Subsidiary (a "Holding Company") of audit, accounting, legal or other similar

respective direct or indirect Holding Company and so long as the aggregate
amount of payments pursuant to this clause (5) does not exceed $1,000,000 in any
calendar year; (6) payments by the Company to repurchase, or to enable a Holding
Company to repurchase, Capital Stock or other securities from employees of the
Company or a Holding Company in an aggregate amount not to exceed $15,000,000;

shall mean the hypo-

                                      -35-

thetical United States tax liability of the Company defined as if the Company
had filed its own U.S. federal tax return for such taxable year); (10) the
payment of any dividend or the making of any distribution to a Holding Company
in amounts sufficient to permit a Holding Company (i) to pay interest when due
on the Senior Discount Notes and (ii) to make any mandatory redemption or
principal payments in respect of the Senior Discount Notes; and (11) payments by
the Company to Hicks Muse Partners in accordance with the terms of the Financial
Advisory Agreement and the Monitoring and Oversight Agreement; provided,
however, that in the case of clauses (3), (4), (6), (7), (8) and (10), no Event
of Default shall have occurred or be continuing at the time of such payment or
as a result thereof. In determining the aggregate amount of Restricted Payments
made subsequent to the Issue Date, amounts expended pursuant to clauses (1),
(4), (6), (7) and (8) shall be included in such calculation.

SECTION 4.11. Notice of Defaults.

              (a) In the event that any Indebtedness of the Company or any of
its Subsidiaries is declared due and payable before its maturity because of the
occurrence of any default (or any event which, with notice or lapse of time, or
both, would constitute such a default) under such Indebtedness, the Company
shall promptly give written notice to the Trustee of such declaration, the
status of such default or event and what action the Company is taking or
proposes to take with respect thereto.

              (b) Upon becoming aware of the occurrence and continuation of any

the extent such submissions are accepted for filing by the Commission, copies of
the annual reports and of the information, documents and other reports that the
Company would have been required to file with the Commission pursuant to Section
13 or 15(d) of the Exchange Act, regardless of whether the Company is then
obligated to file such reports.

SECTION 4.13. Limitations on Dividend and Other Payment Restrictions Affecting
              Restricted Subsidiaries.

              The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause to permit to
exist or become effective, by operation of the charter of such Restricted
Subsidiary or by reason of any agreement, instrument, judgment, decree, rule,
order, statute or governmental regulation, any encumbrance or restriction on the
ability of any Restricted Subsidiary to (a) pay dividends or make any other
distributions on its Capital Stock; (b) make loans or advances or pay any
Indebtedness or other obligation owed to the Company or any of its Restricted
Subsidiaries; or (c) transfer any of its property or assets to the Company,
except for such encumbrances or restrictions existing under or by reason of: (1)
applicable law; (2) this Indenture; (3) customary nonassignment provisions of
any lease governing a leasehold interest of the Company or any Restricted
Subsidiary; (4) any instrument governing Acquired Indebtedness or Acquired
Preferred Stock, which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person, or the
property or assets of the Person, so acquired; (5) agreements existing on the
Issue Date (including the Credit Agreement) as such agreements are from time to
time in effect; provided, however, that any amendments or modifications of such

this covenant shall not result in such encumbrances or restrictions being less


<PAGE>   43

                                      -36-

favorable to the Company in any material respect, as determined in good faith by
the Board of Directors of the Company, than the provisions as in effect before
giving effect to the respective amendment or modification; (6) any restriction

substitution of Indebtedness issued, assumed or incurred pursuant to an
agreement referred to in clause (2), (4) or (5) above or any other agreement
evidencing Indebtedness permitted under this Indenture; provided, however, that
the provisions relating to such encumbrance or restriction contained in any such
refinancing, replacement or substitution agreement or any such other agreement
are no less favorable to the Company in any material respect as determined in
good faith by the Board of Directors of the Company than the provisions relating
to such encumbrance or restriction contained in agreements referred to in such
clause (2), (4) or (5); (8) restrictions on the transfer of the assets subject
to any Lien imposed by the holder of such Lien; (9) a licensing agreement to the
extent such restrictions or encumbrances limit the transfer of property subject
to such licensing agreement; (10) restrictions relating to Subsidiary Preferred
Stock that require that due and payable dividends thereon to be paid in full
prior to dividends on such Subsidiary's common stock; or (11) any agreement or
charter provision evidencing Indebtedness or Capital Stock permitted under this
Indenture; provided, however, that the provisions relating to such encumbrance
or restriction contained in such agreement or charter provision are not less
favorable to the Company in any material respect as determined in good faith by
the Board of Directors of the Company than the provisions relating to such
encumbrance or restriction contained in this Indenture.

SECTION 4.14. Subsidiary Guarantees by Restricted Subsidiaries.

              (a) The Company shall not create or acquire, nor cause or permit
any of its Restricted Subsidiaries, directly or indirectly, to create or
acquire, any Subsidiary other than (1) an Unrestricted Subsidiary in accordance
with the other terms of this Indenture or (2) a Restricted Subsidiary that,
simultaneously with such creation or acquisition, (x) executes and delivers to
the Trustee a supplemental indenture to this Indenture pursuant to which it will
become a Guarantor in accordance with Article Eleven hereof and (y) delivers to
the Trustee an Opinion of Counsel that such supplemental indenture has been duly
authorized, executed and delivered by such Restricted Subsidiary and constitutes
a valid, binding and enforceable obligation of such Restricted Subsidiary (which
opinion may be subject to customary assumptions and qualifications).

              (b) Any Unrestricted Subsidiary that is redesignated as a
Restricted Subsidiary shall upon such redesignation be required to become a
Guarantor in accordance with the requirements of Section 4.14(a)(2).

have the right to require that the Company purchase all or a portion of such
Holder's Securities in cash pursuant to the offer described below (the "Change
of Control Offer"), at a purchase price equal to 101% of the principal amount
thereof plus accrued and unpaid interest, if any, to the date of purchase.

              (b) Prior to the mailing of the notice referred to below, but in
any event within 30 days following the date on which the Company becomes aware
that a Change of Control has occurred (the "Change of Control Date"), the
Company covenants that if the purchase of the Securities would violate or
constitute a default under any other Indebtedness of the Company, then the
Company shall, to the extent needed to permit such purchase of Securities,
either (i) repay all such Indebtedness and terminate all commitments outstanding
thereunder or (ii) obtain the requisite consents, if any, under any such
Indebtedness to permit the purchase of the Securities as provided below. The
Company shall first comply with the covenant in the preceding sentence 

<PAGE>   44

                                      -37-

before it will be required to make the Change of Control Offer or purchase the
Securities pursuant to the provisions described below.

              (c) Within 30 days following the date on which the Company becomes
aware that a Change of Control has occurred, the Company shall send, by first
class mail, postage prepaid, a notice to each Holder, which notice shall govern
the terms of the Change of Control Offer. The notice to the Holders shall
contain all instructions and materials necessary to enable such Holders to
tender Securities pursuant to the Change of Control Offer. Such notice shall
state:

                  (1)    that the Change of Control Offer is being made pursuant
         to this Section 4.15 and that all Securities validly tendered and not
         withdrawn will be accepted for payment;

                  (2)    the purchase price (including the amount of accrued
         interest, if any) and the purchase date (which shall be no earlier than
         30 days nor later than 45 days from the date such notice is mailed,
         other than as may be required by law) (the "Change of Control Payment
         Date");

                  (3)    that any Security not tendered will continue to accrue
         interest;

                  (4)    that, unless the Company defaults in making payment
         therefor, any Security accepted for payment pursuant to the Change of
         Control Offer shall cease to accrue interest after the Change of
         Control Payment Date;

                  (5)    that Holders electing to have a Security purchased
         pursuant to a Change of Control Offer will be required to surrender the
         Security, with the form entitled "Option of Holder to Elect Purchase"
         on the reverse of the Security completed, to the Paying Agent and
         Registrar for the Securities at the address specified in the notice
         prior to the close of business on the Business Day prior to the Change
         of Control Payment Date;

                  (6)    that Holders shall be entitled to withdraw their
         election if the Paying Agent receives, not later than five Business
         Days prior to the Change of Control Payment Date, a telegram, telex,
         facsimile transmission or letter setting forth the name of the Holder,
         the principal amount of the Securities the Holder delivered for
         purchase and a statement that such Holder is withdrawing his election
         to have such Security purchased;

                  (7)    that Holders whose Securities are purchased only in
         part shall be issued new Securities in a principal amount equal to the
         unpurchased portion of the Securities surrendered; provided, however,
         that each Security purchased and each new Security issued shall be in a
         principal amount of $1,000 or integral multiples thereof; and

                  (8)    the circumstances and relevant facts regarding such
         Change of Control.

              (d) On or before the Change of Control Payment Date, the Company
shall (i) accept for payment Securities or portions thereof (in integral
multiples of $1,000) validly tendered pursuant to the Change of Control Offer,
(ii) deposit with the Paying Agent in accordance with Section 2.14 cash in U.S.
dollars or United States Government Obligations sufficient to pay the purchase
price plus accrued and unpaid interest, if any, of all Securities so tendered
and (iii) deliver to the Trustee Securities so accepted together with an
Officers' Certificate stating the Securities or portions thereof being purchased
by the Company. Upon receipt by the Paying Agent of the monies specified in

(iii) 

<PAGE>   45

                                      -38-

above, the Paying Agent shall promptly mail to the Holders of Securities so
accepted payment in an amount equal to the purchase price plus accrued and
unpaid interest, if any, out of the funds deposited with the Paying Agent in
accordance with the preceding sentence. The Trustee shall promptly authenticate
and mail to such Holders new Securities equal in principal amount to any
unpurchased portion of the Securities surrendered. Upon the payment of the
purchase price for the Securities accepted for purchase, the Trustee shall
return the Securities purchased to the Company for cancellation. Any monies
remaining after the purchase of Securities pursuant to a Change of Control Offer
shall be returned within three Business Days by the Trustee to the Company
except with respect to monies owed as obligations to the Trustee pursuant to
Article Eight. For purposes of this Section 4.15, the Trustee shall, except with
respect to monies owed as obligations to the Trustee pursuant to Article Eight,
act as the Paying Agent.

              (e) The Company shall comply with the requirements of Rule 14e-1
under the Exchange Act and any other securities laws and regulations thereunder
to the extent such laws and regulations are applicable in connection with the
purchase of the Securities pursuant to a Change of Control Offer. To the extent
the provisions of any such rule conflict with the provisions of this Indenture
relating to a Change of Control Offer, the Company shall comply with the
provisions of such rule and be deemed not to have breached its obligations
relating to such Change of Control Offer by virtue thereof.

              (f) Paragraphs (a)-(e) of this Section 4.15 notwithstanding, the
Company shall not be required to make a Change of Control Offer if, instead, the
Company elects to effect a Change of Control Redemption in compliance with the
requirements listed on the Securities in Exhibit A and Exhibit B hereof.

              (g) Paragraphs (a)-(f) notwithstanding, the Company shall not be
required to make a Change of Control Offer or a Change of Control Redemption in
the event of (i) changes in a majority of the board of directors of the Company
so long as a majority of such board of directors continues to consist of
Continuing Directors and (ii) certain transactions with Permitted Holders
(including Hicks Muse, its officers and directors, and their respective
Affiliates).

SECTION 4.16. Limitation on Liens.

              The Company shall not, and shall not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur or assume any
Lien securing Indebtedness on any asset now owned or hereafter acquired, or any
income or profits therefrom or assign or convey any right to receive income
therefrom, unless contemporaneously therewith effective provision is made, in
the case of the Company, to secure the Securities and all other amounts due
under this Indenture, and in the case of a Restricted Subsidiary which is a
Guarantor, to secure such Restricted Subsidiary's Subsidiary Guarantee of the
Securities and all other amounts due under this Indenture, equally and ratably
with such Indebtedness (or, in the event that such Indebtedness is subordinated
in right of payment to the Securities or such Subsidiary's Subsidiary Guarantee,
prior to such Indebtedness) with a Lien on the same properties and assets
securing such Indebtedness for so long as such Indebtedness is secured by such
Lien, except for (i) Liens securing Senior Indebtedness and Guarantor Senior
Indebtedness and (ii) Liens securing Indebtedness described in clause (xi) of
the definition of "Permitted Indebtedness"; provided that such Liens cover only
the property referred to in such definition.

SECTION 4.17. Compliance Certificate.

              The Company shall deliver to the Trustee within 120 days after the
close of each fiscal year a certificate signed by the principal executive
officer, principal financial officer or principal accounting officer stating

supervision of the signing officer 


<PAGE>   46

                                      -39-

with a view to determining whether a Default or Event of Default has occurred
and whether or not the signers know of any Default or Event of Default by the
Company that occurred during such fiscal year. If they do know of such a Default
or Event of Default, their status and the action the Company is taking or
proposes to take with respect thereto. The first certificate to be delivered by
the Company pursuant to this Section 4.17 shall be for the fiscal year ending
December 31, 1998.

SECTION 4.18. Corporate Existence.

              Subject to Article Five, the Company shall do or shall cause to be
done all things necessary to preserve and keep in full force and effect its
corporate existence and the corporate, partnership or other existence of each
Subsidiary in accordance with the respective organizational documents of each
such Subsidiary and the rights (charter and statutory) and material franchises
of the Company and the Subsidiaries; provided, however, that the Company shall
not be required to preserve any such right or franchise, or the corporate
existence of any Subsidiary, if the Board of Directors of the Company shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and the Subsidiaries, taken as a whole; provided,
further, however, that a determination of the Board of Directors of the Company
shall not be required in the event of a merger of one or more Restricted
Subsidiaries of the Company with or into another Restricted Subsidiary of the
Company or another Person, if the surviving Person is a Restricted Subsidiary of
the Company organized under the laws of the United States or a State thereof or
of the District of Columbia. This Section 4.18 shall not prohibit the Company
from taking any other action otherwise permitted by, and made in accordance
with, the provisions of this Indenture.

SECTION 4.19. Maintenance of Properties and Insurance.

              (a) The Company shall, and shall cause each of its Restricted
Subsidiaries to, maintain its material properties in normal condition (subject
to ordinary wear and tear) and make all reasonably necessary repairs, renewals
or replacements thereto as in the judgment of the Company may be reasonably
necessary to the conduct of the business of the Company and its Restricted
Subsidiaries; provided, however, that nothing in this Section 4.19 shall prevent
the Company or any of its Restricted Subsidiaries from discontinuing the
operation and maintenance of any of its properties, if such properties are, in
the reasonable and good faith judgment of the Board of Directors of the Company
or the Restricted Subsidiary, as the case may be, no longer reasonably necessary
in the conduct of their respective businesses.

              (b) The Company shall provide or cause to be provided, for itself
and each of its Restricted Subsidiaries, insurance (including appropriate
self-insurance) against loss or damage of the kinds that, in the reasonable,
good faith opinion of the Company, are reasonably adequate and appropriate for
the conduct of the business of the Company and such Restricted Subsidiaries.

SECTION 4.20. Payment of Taxes and Other Claims.

              The Company shall pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (i) all material taxes,
assessments and governmental charges (including withholding taxes and any
penalties, interest and additions to taxes) levied or imposed upon it or any of
its Restricted Subsidiaries or properties of it or any of its Restricted
Subsidiaries and (ii) all material lawful claims for labor, materials, supplies
and services that, if unpaid, might by law become a Lien upon the property of it
or any of its Restricted Subsidiaries; provided, however, that there shall not
be required to be paid or discharged any such tax, assessment or charge, the
amount, applicability or validity of which is being contested in good faith by
appropriate

                                      -40-

proceedings and for which adequate provision has been made or where the failure
to effect such payment or discharge is not adverse in any material respect to
the Holders.

SECTION 4.21. Waiver of Stay, Extension or Usury Laws.

              The Company covenants (to the extent that it may lawfully do so)
that it will not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law or any
usury law or other law that would prohibit or forgive the Company from paying
all or any portion of the principal of, premium or interest on the Securities as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the obligations or the performance of this Indenture; and (to
the extent that it may lawfully do so) the Company hereby expressly waives all
benefit or advantage of any such law, and covenants that it 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.

                                   ARTICLE SIX

                              DEFAULT AND REMEDIES


SECTION 6.01. Events of Default.

              Each of the following shall be an "Event of Default" for purposes
of this Indenture:

                  (a) the failure to pay interest on any Security when the same
         becomes due and payable and the Default continues for a period of 30
         days (whether or not such payment is prohibited by Article Seven;

                  (b) the failure to pay principal of or premium, if any, on any
         Security when such principal or premium, if any, becomes due and
         payable, at maturity, upon redemption or otherwise (whether or not such
         payment is prohibited by Article Seven);

                  (c) a default in the observance or performance of any other
         covenant or agreement contained in the Securities or this Indenture,
         which default continues for a period of 30 days after the Company
         receives written notice thereof specifying the default from the Trustee
         or Holders of at least 25% in aggregate principal amount of outstanding
         Securities;

                  (d) the failure to pay at the final stated maturity (giving
         effect to any extensions thereof) the principal amount of any
         Indebtedness of the Company or any Restricted Subsidiary of the
         Company, or the acceleration of the final stated maturity of any such
         Indebtedness, if the aggregate principal amount of such Indebtedness,
         together with the aggregate principal amount of any other such
         Indebtedness in default for failure to pay principal at the final
         stated maturity (giving effect to any extensions thereof) or which has
         been accelerated, aggregates $10,000,000 or more at any time in each
         case after a 10-day period during which such default shall not have
         been cured or such acceleration rescinded;

                  (e) one or more judgments in an aggregate amount in excess of
         $15,000,000 (which are not covered by insurance as to which the insurer
         has not disclaimed coverage) being rendered against the 


<PAGE>   49

                                      -42-

         Company or any of its Significant Restricted Subsidiaries and such
         judgment or judgments remain undischarged or unstayed for a period of
         60 days after such judgment or judgments become final and
         nonappealable;

                  (f) the Company or any of its Significant Restricted
         Subsidiaries (or one or more Restricted Subsidiaries that, taken
         together would constitute a Significant Restricted Subsidiary) pursuant
         to or within the meaning of any Bankruptcy Law: (i) admits in writing
         its inability to pay its debts generally as they become due; (ii)
         commences a voluntary case or proceeding; (iii) consents to the entry
         of an order for relief against it in an involuntary case or proceeding;
         (iv) consents or acquiesces in the institution of a bankruptcy or
         insolvency proceeding against it; (v) consents to the appointment of a
         Custodian of it or for all or substantially all of its property; or
         (vi) makes a general assignment for the benefit of its creditors, or
         any of them takes any action to authorize or effect any of the
         foregoing;

                  (g) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that: (i) is for relief against the
         Company or any Significant Restricted Subsidiary (or one or more
         Restricted Subsidiaries that, taken together would constitute a
         Significant Restricted Subsidiary) of the Company in an involuntary
         case or proceeding; (ii) appoints a Custodian of the Company or any
         Significant Restricted Subsidiary (or one or more Restricted
         Subsidiaries that, taken together would constitute a Significant
         Restricted Subsidiary) of the Company for all or substantially all of
         its property; or (iii) orders the liquidation of the Company or any
         Significant Restricted Subsidiary (or one or more Restricted
         Subsidiaries that, taken together would constitute a Significant
         Restricted Subsidiary) of the Company; and in each case the order or
         decree remains unstayed and in effect for 60 days; provided, however,
         that if the entry of such order or decree is appealed and dismissed on
         appeal, then the Event of Default hereunder by reason of the entry of
         such order or decree shall be deemed to have been cured; or

                  (h) except as permitted by this Indenture, any Subsidiary
         Guarantee shall be held in a judicial proceeding to be unenforceable or
         invalid or shall cease for any reason to be in full force and effect or
         any Guarantor, or any Person acting on behalf of any Guarantor, shall
         deny or disaffirm its obligations under its Subsidiary Guarantee.

SECTION 6.02. Acceleration.

              If an Event of Default with respect to the Securities (other than
an Event of Default specified in clause (f) or (g) of Section 6.01) occurs and
is continuing, the Trustee may, or the Trustee upon the request of Holders of
25% in principal amount of the outstanding Securities shall, or the Holders of
at least 25% in aggregate principal amount of the outstanding Securities may
declare the principal of all the Securities, together with all accrued and
unpaid interest and premium, if any, to be due and payable by notice in writing
to the Company and the Trustee specifying the respective Event of Default and
that it is a "notice of acceleration" (the "Acceleration Notice"), and the same
(i) shall become immediately due and payable or (ii) if there are any amounts
outstanding under the Senior Credit Facilities, will become due and payable upon
the first to occur of an acceleration under the Senior Credit Facilities or five
Business Days after receipt by the Company and the agent under the Senior Credit
Facilities of such Acceleration Notice (unless all Events of Default specified
in such Acceleration Notice have been cured or waived).

              If an Event of Default specified in clause (f) or (g) of Section
6.01 occurs, all unpaid principal of and accrued interest on all outstanding
Securities shall ipso facto become immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder.

<PAGE>   50

                                      -43-

              At any time after such declaration with respect to the Securities,
the Holders of a majority in principal amount of Securities then outstanding (by
notice to the Trustee) may rescind and cancel such declaration and its
consequences if (i) the rescission would not conflict with any judgment or
decree of a court of competent jurisdiction, (ii) all existing Defaults and
Events of Default have been cured or waived except nonpayment of principal of or
interest on the Securities that has become due solely by such declaration of
acceleration, (iii) to the extent the payment of such interest is lawful,
interest (at the same rate specified in the Securities) on overdue installments
of interest and overdue payments of principal, which has become due otherwise
than by such declaration of acceleration has been paid, (iv) the Company has
paid the Trustee its reasonable compensation and reimbursed the Trustee for its
reasonable expenses, disbursements and advances and (v) in the event of the cure
or waiver of a Default or Event of Default of the type described in clause (f)
or (g) of Section 6.01, the Trustee has received an Officers' Certificate and
Opinion of Counsel that such Default or Event of Default has been cured or
waived. The Holders of a majority in principal amount of the Securities may
waive any existing Default or Event of Default under this Indenture, and its
consequences, except a default in the payment of the principal of or interest on
any Securities. No such rescission shall affect any subsequent Default or impair
any right consequent thereto.

SECTION 6.03. Other Remedies.

              If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of or interest on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.

              The Trustee may maintain a proceeding even if it does not possess
any of the Securities or does not produce any of them in the proceeding. A delay
or omission by the Trustee or any Holder in exercising any right or remedy
maturing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative to the
extent permitted by law.

SECTION 6.04. Waiver of Past Default.

              Subject to Sections 2.09, 6.07 and 10.02, prior to the declaration
of acceleration of the Securities, the Holders of not less than a majority in
aggregate principal amount of the outstanding Securities by written notice to
the Trustee may waive an existing Default or Event of Default and its
consequences, except a Default in the payment of principal of or interest on any
Security as specified in clauses (a), (b), (c) and (d) of Section 6.01 or a
Default in respect of any term or provision of this Indenture that may not be
amended or modified without the consent of each Holder affected as provided in
Section 10.02. The Company shall deliver to the Trustee an Officers' Certificate
stating that the requisite percentage of Holders have consented to such waiver
and attaching copies of such consents. In case of any such waiver, the Company,
the Trustee and the Holders shall be restored to their former positions and
rights hereunder and under the Securities, respectively. This paragraph of this
Section 6.04 shall be in lieu of ss. 316(a)(1)(B) of the TIA and such ss.
316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the
Securities, as permitted by the TIA.

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

SECTION 6.05. Control by Majority.

              Subject to Section 2.09, the Holders of a majority in principal
amount of the outstanding Securities may 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 it. However, the Trustee may refuse to follow
any direction that conflicts with law or this Indenture that the Trustee
determines may be unduly prejudicial to the rights of another Holder, it being
understood that the Trustee shall have no duty (subject to Section 8.01) to
ascertain whether or not such actions or forebearances are unduly prejudicial to
such Holders, or that may involve the Trustee in personal liability; provided,
however, that the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction. In the event the Trustee takes
any action or follows any direction pursuant to this Indenture, the Trustee
shall be entitled to indemnification satisfactory to it in its sole discretion
against any loss or expense caused by taking such action or following such
direction. This Section 6.05 shall be in lieu of ss. 316(a)(1)(A) of the TIA,
and such ss. 316(a)(1)(A) of the TIA is hereby expressly excluded from this
Indenture and the Securities, as permitted by the TIA.

SECTION 6.06. Limitation on Suits.

              A Holder may not pursue any remedy with respect to this Indenture
or the Securities unless:

                   (i)   the Holder gives to the Trustee written notice of a 
         continuing Event of Default;

                  (ii)   the Holders of at least 25% in aggregate principal
         amount of the outstanding Securities make a written request to the
         Trustee to pursue a remedy;

                 (iii)   such Holder or Holders offer and, if requested, provide
         to the Trustee indemnity satisfactory to the Trustee against any loss,
         liability or expense;

                  (iv)   the Trustee does not comply with the request within 60
         days after receipt of the request and the offer and, if requested, the
         provision of indemnity; and

                   (v)   during such 60-day period the Holders of a majority in
         principal amount of the outstanding Securities do not give the Trustee
         a direction which, in the opinion of the Trustee, is inconsistent with
         the request.

              A Holder may not use this Indenture to prejudice the rights of
another Holder or to obtain a preference or priority over such other Holder.

SECTION 6.07. Rights of Holders To Receive Payment.

              Notwithstanding any other provision of this Indenture, the right
of any Holder to receive payment of principal of or interest on a Security, on
or after the respective due dates expressed in the Security, or to bring 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 6.08. Collection Suit by Trustee.

              If an Event of Default in payment of principal or interest
specified in Section 6.01(a), (b), (c) or (d) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust
against the Company or any other obligor on the Securities for the whole amount
of principal and accrued interest remaining unpaid, together with interest
overdue on principal and to the extent that payment of such interest is lawful,
interest on overdue installments of interest, in each case at the rate per annum
borne by the 

<PAGE>   52

                                      -45-

Securities and such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09. Trustee May File Proofs of Claim.

              The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders allowed in any judicial proceedings relative to the Company (or any
other obligor upon the Securities), its creditors or its property and shall be
entitled and empowered to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same, and any
Custodian in any such judicial proceedings is hereby authorized by each Holder
to make such payments to the Trustee and, in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agent and counsel, and any other
amounts due the Trustee under Section 8.07. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding; provided, however, that the Trustee may, on behalf of the Holders,
vote for the election of a trustee in bankruptcy or similar official and may be
a member of the creditors' committee.

SECTION 6.10. Priorities.

              If the Trustee collects any money or property pursuant to this
Article Six, it shall pay out the money or property in the following order:

              First: to the Trustee for amounts due under Section 8.07;

              Second: to Holders for amounts due and unpaid on the Securities
     for principal and interest, ratably, without preference or priority of any
     kind, according to the amounts due and payable on the Securities for
     principal and interest, respectively; and

              Third: to the Company.

              The Trustee, upon prior written notice to the Company, may fix a
record date and payment date for any payment to the Holders pursuant to this
Section 6.10.

SECTION 6.11. Undertaking for Costs.

              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, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.11 shall not apply to a suit by the Trustee, a suit by
a Holder or group of Holders of more than 10% in aggregate principal amount of
the outstanding Securities, or to any suit instituted by any Holder for the
enforcement or the payment of the principal or interest on any Securities on or
after the respective due dates expressed in the Security.

                                  ARTICLE SEVEN

                           SUBORDINATION OF SECURITIES


SECTION 7.01. Agreement To Subordinate.

              The Company agrees, and each Holder by accepting any Security
agrees, that the Indebtedness evidenced by the Securities is subordinated in
right of payment, to the extent and in the manner provided in this Article
Seven, to the payment when due of all Senior Indebtedness of the Company and
that such subordination is for the benefit of and enforceable by the holders of
Senior Indebtedness. The Securities shall in all respects rank pari passu with
all other Senior Subordinated Indebtedness of the Company, and only Indebtedness
of the Company which is Senior Indebtedness will rank senior to the Securities
in accordance with the provisions set forth herein. Unsecured Indebtedness is
not deemed to be subordinate or junior to Secured Indebtedness merely because it
is unsecured, nor is any Indebtedness deemed to be subordinate or junior to
other Indebtedness merely because it matures after such other Indebtedness.
Secured Indebtedness is not deemed to be Senior Indebtedness merely because it
is secured. All provisions of this Article Seven shall be subject to Section
7.12.

SECTION 7.02. Liquidation, Dissolution, Bankruptcy.

              Upon any payment or distribution of the assets of the Company upon
a total or partial liquidation or dissolution or reorganization or bankruptcy of
or similar proceeding relating to the Company or its property:

              (1) holders of Senior Indebtedness of the Company shall be
     entitled to receive payment in full in cash or Cash Equivalents of all
     Senior Indebtedness of the Company before holders of Securities shall be
     entitled to receive any payment of principal of or interest on or other
     amounts with respect to the Securities from the Company; and

              (2) until the Senior Indebtedness of the Company is paid in full,
     in cash or Cash Equivalents, any payment or distribution to which Holders
     would be entitled but for the provisions of this Article Seven shall be
     made to holders of Senior Indebtedness as their interests may appear.

SECTION 7.03. Default on Senior Indebtedness.

              The Company may not pay the principal of, premium (if any), or
interest on, and other obligations with respect to, the Securities or make any
deposit pursuant to Section 9.03 or repurchase, redeem or otherwise retire any
Securities (collectively, "pay the Securities") if (i) any Senior Indebtedness
is not paid when due or (ii) any other default on Senior Indebtedness occurs and
the maturity of such Senior Indebtedness is accelerated in accordance with its
terms unless, in either case, (x) the default has been cured or waived or is no
longer continuing and/or any such acceleration has been rescinded or (y) such
Senior Indebtedness has been paid in full; provided, however, that the Company
may pay the Securities, subject to the provisions of Section 7.02, without
regard to the foregoing if the Company and the Trustee receive written notice
approving such payment from the Representatives of the Senior Indebtedness with
respect to which either of the events set forth in clause (i) or (ii) of this
sentence has occurred or is continuing. During the continuance of any default
(other than a default described in clause (i) or (ii) of the preceding sentence)
with respect to any Designated Senior Indebtedness pursuant to which the
maturity thereof may be accelerated immediately without further notice

(except such notice as may be required to effect such acceleration) or the
expiration of any applicable grace periods, the Company may not pay the
Securities (except (i) in Qualified Capital Stock issued by the Company to pay
interest on the Securities or issued in exchange for the Securities, (ii) in
securities substantially identical to the Securities issued by the Company in
payment of interest accrued thereon or (iii) in securities issued by the Company
which are subordinated to the Senior Indebtedness at least to the same extent as
the Securities and having a Weighted Average Life to Maturity at least equal to
the remaining Weighted Average Life to Maturity of the Securities) for a period
(a "Payment Blockage Period") commencing upon the receipt by the Trustee (with a
copy to the Company) of written notice (a "Blockage Notice") of such default
from the Representative of the holders of such Designated Senior Indebtedness
specifying an election to effect a Payment Blockage Period and ending 179 days
thereafter (or earlier if such Payment Blockage Period is terminated (i) by
written notice to the Trustee and the Company from the Person or Persons who
gave such Blockage Notice, (ii) because the default giving rise to such Blockage
Notice has been cured, waived or is no longer continuing or (iii) because such
Designated Senior Indebtedness has been repaid in full). Notwithstanding the
provisions of the immediately preceding sentence, but subject to the provisions
of the first sentence of this Section 7.03 and the provisions of Section 7.02,
the Company may resume payments on the Securities after the end of such Payment
Blockage Period. Not more than one Blockage Notice may be given, and not more
than one Payment Blockage Period may occur, in any consecutive 360-day period,
irrespective of the number of defaults with respect to Designated Senior
Indebtedness during such period. However, if any Blockage Notice within such
360-day period is given by or on behalf of any holders of Designated Senior
Indebtedness (other than the agent under the Senior Credit Facilities), the
agent under the Senior Credit Facilities may give another Blockage Notice within
such period. In no event, however, may the total number of days during which any
Payment Blockage Period or Payment Blockage Periods are in effect exceed 179
days in the aggregate during any 360 consecutive day period. No nonpayment
default that existed or was continuing on the date of delivery of any Blockage
Notice to the Trustee shall be, or be made, the basis for a subsequent Blockage
Notice unless such default shall have been cured or waived for a period of not
less than 90 consecutive days.

SECTION 7.04. Acceleration of Payment of Securities.

              If payment of the Securities is accelerated because of an Event of
Default, the Company or the Trustee shall promptly notify the holders of the
Representative (if any) of any issue of Designated Senior Indebtedness which is
then outstanding; provided, however, that the Company and the Trustee shall be
obligated to notify such a Representative (other than with respect to the Senior
Credit Facilities) only if such Representative has delivered or caused to be
delivered an address for the service of such a notice to the Company and the
Trustee (and the Company and the Trustee shall be obligated only to deliver the
notice to the address so specified). If a notice is required pursuant to the
immediately preceding sentence, the Company may not pay the Securities (except
payment (i) in Qualified Capital Stock issued by the Company to pay interest on
the Securities or issued in exchange for the Securities, (ii) in securities
substantially identical to the Securities issued by the Company in payment of
interest accrued thereon or (iii) securities issued by the Company which are
subordinated to the Senior Indebtedness at least to the same extent as the
Securities and have a Weighted Average Life to Maturity at least equal to the
remaining Weighted Average Life to Maturity of the Securities), until five
Business Days after the respective Representative of the Designated Senior
Indebtedness receives notice (at the address specified in the preceding
sentence) of such acceleration and thereafter may pay the Securities only if the
provisions of this Article Seven otherwise permit payment at that time.

SECTION 7.05. When Distribution Must Be Paid Over.

              If a distribution is made to the Trustee or to Holders that
because of this Article Seven should not have been made to them, the Trustee or
the Holders who receive such distribution shall hold it in trust for 


<PAGE>   55

                                      -48-

holders of Senior Indebtedness and promptly pay it over to them as their
respective interests may appear; provided, however, that the liabilities of the
Trustee under this Section 7.05 are limited by Section 7.15.

SECTION 7.06. Subrogation.

              After all Senior Indebtedness is paid in full and until the
Securities are paid in full, Holders shall be subrogated to the rights of
holders of Senior Indebtedness to receive distributions applicable to Senior
Indebtedness. A distribution made under this Article Seven to holders of Senior
Indebtedness which otherwise would have been made to Holders is not, as between
the Company and the Holders, a payment by the Company of Senior Indebtedness.

SECTION 7.07. Relative Rights.

              This Article Seven defines the relative rights of Holders of the
Securities on the one hand and holders of Senior Indebtedness on the other hand.
Nothing in this Indenture shall:

              (1)   impair, as between the Company and the Holders, the
     obligation of the Company, which is absolute and unconditional, to pay
     principal of and interest on the Securities in accordance with their terms;
     or

              (2)   prevent the Trustee or any Holder from exercising its 
     available remedies upon a Default or Event of Default, subject to the
     rights of holders of Senior Indebtedness to receive distributions otherwise
     payable to Holders.

SECTION 7.08. Subordination May Not Be Impaired by Company.

              No right of any holder of Senior Indebtedness to enforce the
subordination of the Indebtedness evidenced by the Securities shall be impaired
by any act or failure to act by the Company or by the failure of the Company to
comply with this Indenture.

SECTION 7.09. Rights of Trustee and Paying Agent.

              Notwithstanding Section 7.03, the Trustee or Paying Agent may
continue to make payments on the Securities and shall not be charged with
knowledge of the existence of facts that would prohibit the making of any such
payments unless, not less than two Business Days prior to the date of such
payment, a Trust Officer of the Trustee receives notice satisfactory to it that
payments may not be made under this Article Seven. The Company, the Registrar or
co-registrar, the Paying Agent, a Representative or a holder of Senior
Indebtedness may give the notice; provided, however, that if an issue of Senior
Indebtedness has a Representative, only the Representative may give the notice.

              The Trustee in its individual or any other capacity may hold
Senior Indebtedness with the same rights it would have if it were not Trustee.
The Registrar and co-registrar and the Paying Agent may do the same with like
rights. The Trustee shall be entitled to all the rights set forth in this
Article Seven with respect to any Senior Indebtedness which may at any time be
held by it, to the same extent as any other holder of Senior Indebtedness; and
nothing in Article Seven shall deprive the Trustee of any of its rights as such
holder. Nothing in this Article Seven shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 8.07.

                                      -49-

SECTION 7.10. Distribution or Notice to Representative.

              Whenever a distribution is to be made or a notice given to holders
of Senior Indebtedness, the distribution may be made and the notice given to
their Representative (if any).

SECTION 7.11. Article Seven Not To Prevent Events of Default or Limit Right To
              Accelerate.

              The failure to make a payment in respect of the Securities by
reason of any provision in this Article Seven shall not be construed as
preventing the occurrence of a Default or Event of Default. Nothing in this
Article Seven shall have any effect on the right of the Holders or the Trustee
to accelerate the maturity of the Securities.

SECTION 7.12. Trust Moneys Not Subordinated.

              Notwithstanding anything contained herein to the contrary,
payments from money or the proceeds of U.S. Government Obligations held in trust
under Article Nine by the Trustee for the payment of principal of and interest
on the Securities shall not be subordinated to the prior payment of any Senior
Indebtedness or subject to the restrictions set forth in this Article Seven, and
none of the Holders shall be obligated to pay over any such amount to the
Company, any holder of Senior Indebtedness of the Company, or any other creditor
of the Company.

SECTION 7.13. Trustee Entitled To Rely.

              Upon any payment or distribution pursuant to this Article Seven,
the Trustee and the Holders shall be entitled to rely (i) upon any order or
decree of a court of competent jurisdiction in which any proceedings of the
nature referred to in Section 7.02 are pending, (ii) upon a certificate of the
liquidating trustee or agent or other Person making such payment or distribution
to the Trustee or to the Holders or (iii) upon the Representatives for the
holders of Senior Indebtedness for the purpose of ascertaining the Persons
entitled to participate in such payment or distribution, the holders of Senior
Indebtedness and other Indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article Seven. In the event that the Trustee
determines, in good faith, that 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 Seven, the Trustee may request such
Person to furnish evidence to the reasonable satisfaction of the Trustee as to
the amount of Senior Indebtedness held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and other
facts pertinent to the rights of such Person under this Article Seven, 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. The Trustee shall have the right to seek a declaratory judgment as to
any right of such Person to receive such payment. The provisions of Sections
8.01 and 8.02 shall be applicable to all actions or omissions of actions by the
Trustee pursuant to this Article Seven.

SECTION 7.14. Trustee To Effectuate Subordination.

              Each Holder by accepting a Security authorizes and directs the
Trustee on his behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination between the Holder and the holders
of Senior Indebtedness as provided in this Article Seven and appoints the
Trustee as attorney-in-fact for any and all such purposes.

<PAGE>   57

                                      -50-

SECTION 7.15. Trustee Not Fiduciary for Holders of Senior Indebtedness.

              The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness and shall not be liable to any such holders if it
shall mistakenly pay over or distribute to Holders or the Company, or any other
Person, money or assets to which any holders of Senior Indebtedness shall be
entitled by virtue of this Article Seven or otherwise.

SECTION 7.16. Reliance by Holders of Senior Indebtedness on Subordination
              Provisions.

              Each Holder by accepting a Security acknowledges and agrees that
the foregoing subordination provisions are, and are intended to be, an
inducement and a consideration to each holder of any Senior Indebtedness,
whether such Senior Indebtedness was created or acquired before or after the
issuance of the Securities, to acquire and continue to hold, or to continue to
hold, such Senior Indebtedness and such holder of Senior Indebtedness shall be
deemed conclusively to have relied on such subordination provisions in acquiring
and continuing to hold, or in continuing to hold, such Senior Indebtedness.


                                  ARTICLE EIGHT

                                     TRUSTEE


SECTION 8.01. Duties of Trustee.

              (a) If a Default has occurred and is continuing, 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 man would
exercise or use under the circumstances in the conduct of his own affairs.

              (b) Except during the continuance of a Default:

              (1)   The Trustee shall not be liable except for the performance
     of such duties as are specifically set forth herein; and

              (2)   In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions conforming to
     the requirements of this Indenture; provided, however, that 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
     examine such certificates and opinions to determine whether or not they
     conform to the requirements of this Indenture.

              (c) The Trustee shall not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

               (1)  This paragraph does not limit the effect of paragraph (b) of
     this Section 8.01;

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


<PAGE>   58

                                      -51-

               (3)  The Trustee shall not be liable with respect to any action
     it takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Sections 6.02, 6.04 and 6.05.

              (d) 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 to take or omit to take any action
under this Indenture or take any action at the request or direction of Holders
if it shall have reasonable grounds for believing that repayment of such funds
is not assured to it or it does not receive from such Holders an indemnity
satisfactory to it in its sole discretion against such risk, liability, loss,
fee or expense which might be incurred by it in compliance with such request or
direction.

              (e) Every provision of this Indenture that in any way relates to
the Trustee is subject to paragraphs (a), (b), (c) and (d) of this Section 8.01.

              (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.
Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by law.

SECTION 8.02. Rights of Trustee.

              Subject to Section 8.01:

              (a) The Trustee may rely on any document believed by it to be
       genuine and to have been signed or presented by the proper Person. The
       Trustee need not investigate any fact or matter stated in the document.

              (b) Before the Trustee acts or refrains from acting, it may
       require an Officers' Certificate and/or an Opinion of Counsel, which
       shall conform to the provisions of Section 13.05. The Trustee shall not
       be liable for any action it takes or omits to take in good faith in
       reliance on such certificate or opinion.

              (c) The Trustee may act through attorneys and agents of its
       selection and shall not be responsible for the misconduct or negligence
       of any agent or attorney (other than an agent who is an employee of the
       Trustee) appointed with due care and appointed with the consent of the
       Company.

              (d) The Trustee shall not be liable for any action it takes or
       omits to take in good faith which it reasonably believes to be authorized
       or within its rights or powers.

              (e) Before the Trustee acts or refrains from acting, it may
       consult with counsel and the advice or opinion of such counsel as to
       matters of law shall be full and complete authorization and protection
       from liability in respect of any action taken, omitted or suffered by it
       hereunder in good faith and in accordance with the advice or opinion of
       such counsel.

              (f) Any request or direction of the Company mentioned herein shall
       be sufficiently evidenced by a Company Request or Company Order and any
       resolution of the Board of Directors may be sufficiently evidenced by a
       Board Resolution.

              (g) The Trustee shall be under no obligation to exercise any of
       the rights or powers vested in it by this Indenture at the request or
       direction of any of the Holders pursuant to this Indenture, unless 


<PAGE>   59

                                      -52-

       such Holders shall have offered to the Trustee reasonable security or
       indemnity against the costs, expenses and liabilities which might be
       incurred by it in compliance with such request or direction.

              (h) 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, note, other evidence of indebtedness or other paper or
       document, but the Trustee, in its discretion, may make such further
       inquiry or investigation into such facts 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.

              (i) The Trustee shall not be deemed to have notice of any Event of
       Default unless a Trust Officer of the Trustee has actual knowledge
       thereof or unless the Trustee shall have received written notice thereof
       at the Corporate Trust Office of the Trustee, and such notice references
       the Securities and this Indenture.

              (j) The Trustee shall not be required to give any bond or surety
       in respect of the performance of its powers and duties hereunder.

              (k) The permissive rights of the Trustee to do things enumerated
       in this Indenture shall not be construed as a duty and the Trustee shall
       not be answerable for other than its gross negligence or willful
       misconduct.

SECTION 8.03. Individual Rights of Trustee.

              The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or their
Affiliates with the same rights it would have if it were not Trustee. Any Agent
may do the same with like rights. However, the Trustee is subject to Sections
8.10 and 8.11.

SECTION 8.04. Trustee's Disclaimer.

              The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture or the
Securities, it shall not be accountable for the Company's use of the proceeds
from the Securities, and it shall not be responsible for any statement of the
Company or any Guarantor in this Indenture or any document issued in connection
with the sale of Securities or any statement in the Securities other than the
Trustee's certificate of authentication.

SECTION 8.05. Notice of Defaults.

              If a Default or an Event of Default occurs and is continuing and
the Trustee has actual knowledge of such Defaults or Events of Default, the
Trustee shall mail to each Holder notice of the Default or Event of Default
within 30 days after the occurrence thereof. Except in the case of a Default or
an Event of Default in payment of principal of or interest on any Security or a
Default or Event of Default in complying with Section 5.01, the Trustee may
withhold the notice if and so long as a committee of its Trust Officers in good
faith determines that withholding the notice is in the interest of the Holders.
This Section 8.05 shall be in lieu of the proviso to ss. 315(b) of the TIA and
such proviso to ss. 315(b) of the TIA is hereby expressly excluded from this
Indenture and the Securities, as permitted by the TIA.

                                      -53-

SECTION 8.06. Reports by Trustee to Holders.

              If required by TIA ss. 313(a), within 60 days after each February
1 beginning with March 1, 1997, the Trustee shall mail to each Holder a report
dated as of such February 1 that complies with TIA ss. 313(a). The Trustee also
shall comply with TIA ss. 313(b), (c) and (d).

              A copy of each such report at the time of its mailing to Holders
shall be filed with the Commission and each stock exchange, if any, on which the
Securities are listed.

              The Company shall promptly notify the Trustee in writing if the
Securities become listed on any stock exchange or of any delisting thereof.

SECTION 8.07. Compensation and Indemnity.

              The Company and the Guarantors shall pay to the Trustee and the
Agents from time to time, and the Trustee and the Agents shall be entitled to,
such compensation as the Company and the Trustee and the Agents shall from time
to time agree in writing for their respective services. The Trustee's
compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Company and the Guarantors shall reimburse the Trustee and
the Agents upon request for all reasonable disbursements, expenses and advances,
including all costs and expenses of collection and reasonable fees,
disbursements and expenses of its agents and outside counsel incurred or made by
any of them in addition to the compensation for their respective services except
any such disbursements, expenses and advances as may be attributable to
negligence or willful misconduct of the party to be reimbursed. Such expenses
shall include the reasonable compensation, disbursements and expenses of the
Trustee's agents, accountants, experts and outside counsel and any taxes or
other expenses incurred by a trust created pursuant to Section 9.01 hereof.

              The Company and the Guarantors shall indemnify the Trustee and the
Agents for, and hold them harmless against any and all loss, damage, claims,
liability or expense, including taxes (other than franchise taxes imposed on the
indemnified party and taxes based upon, measured by or determined by the income
of the indemnified party), arising out of or in connection with the acceptance
or administration of the trust or trusts hereunder, including the costs and
expenses of defending themselves against or investigating any claim or liability
in connection with the exercise or performance of any of their powers or duties
hereunder, except to the extent that such loss, damage, claim, liability or
expense is due to negligence or willful misconduct of the indemnified party. The
indemnified party shall notify the Company promptly of any claim asserted
against the indemnified party for which it may seek indemnity. However, the
failure by the indemnified party to so notify the Company shall not relieve the
Company and the Guarantors of their obligations hereunder unless the Company and
the Guarantors have been prejudiced thereby. The Company and the Guarantors
shall defend the claim and the indemnified party shall cooperate in the defense
at the expense of the Company and the Guarantors; provided that the Company and
the Guarantors shall not be liable in any action or for which they have assumed
the defense for the expenses of separate counsel to the indemnified party unless
(1) the employment of separate counsel has been authorized by the Company and
the Guarantors, (2) the indemnified party has reasonably concluded (based upon
advice of counsel to the indemnified party) that there may be legal defenses
available to the indemnified party that are different from or in addition to
those available to the Company and the Guarantors or (3) a conflict or potential
conflict exists (based upon advice of counsel to the indemnified party) between
the indemnified party, the Company and the Guarantors; provided further,
however, that in any such event the reimbursement obligation of the Company and
the Guarantors with respect to separate counsel of the indemnified party will be
limited to the reasonable fees and expenses of such counsel.

<PAGE>   61

                                      -54-

              The Company and the Guarantors need not pay for any settlement
made without their written consent, which consent shall not be unreasonably
withheld. The Company and the Guarantors need not reimburse any expense or
indemnify against any loss or liability incurred by the Trustee or an Agent as a
result of its own negligence or willful misconduct.

              To secure the payment obligations of the Company and the
Guarantors in this Section 8.07, the Trustee shall have a Lien prior to the
Securities against all money or property held or collected by the Trustee, in
its capacity as Trustee, except money or property held in trust to pay principal
of or interest on particular Securities.

              When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(f) or (g) occurs, the expenses
(including the reasonable fees and expenses of its agents and counsel) and the
compensation for the services shall be preferred over the status of the Holders
in a proceeding under any Bankruptcy Law and are intended to constitute expenses
of administration under any Bankruptcy Law.

SECTION 8.08. Replacement of Trustee.

              The Trustee may resign at any time by so notifying the Company in
writing. The Holders of a majority in principal amount of the outstanding
Securities may remove the Trustee by so notifying the Trustee and the Company in
writing and may appoint a successor Trustee with the Company's consent. The
Company may remove the Trustee if:

              (a) the Trustee fails to comply with Section 8.10;

              (b) the Trustee is adjudged bankrupt or insolvent or an order for
     relief is entered with respect to the Trustee under any Bankruptcy Law;

              (c) a Custodian or other public officer takes charge of the
     Trustee or its property; or

              (d) the Trustee becomes incapable of acting.

              If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason (the Trustee in such event being referred to
herein as the retiring Trustee), the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the Securities may appoint a successor
Trustee to replace the successor Trustee appointed by the Company.

              A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. As promptly as
practicable after that, the retiring Trustee shall transfer, after payment of
all sums then owing to the Trustee pursuant to Section 8.07, all property held
by it as Trustee to the successor Trustee, subject to the Lien provided in
Section 8.07, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have the rights, powers and duties of
the Trustee under this Indenture. A successor Trustee shall mail notice of its
succession to each Holder.

              If a successor Trustee does not take office within 60 days after
the retiring Trustee resigns or is removed, the retiring Trustee, the Company or
the Holders of at least 10% in principal amount of the outstanding Securities
may petition, at the expense of the Company, any court of competent jurisdiction
for the appointment of a successor Trustee.

<PAGE>   62

                                      -55-

              If the Trustee fails to comply with Section 8.10, any Holder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

              Notwithstanding replacement of the Trustee pursuant to this
Section 8.08, the Company's obligations under Section 8.07 shall continue for
the benefit of the retiring Trustee.

         irrevocably deposited or caused to be deposited with the Trustee funds
         in an amount sufficient to pay and discharge the entire Indebtedness on

              After such delivery or irrevocable deposit, the Trustee upon
request shall acknowledge in writing the discharge of the Company's and
Guarantors' obligations under the Securities, the Subsidiary Guarantees and this
Indenture except for those surviving obligations specified above.

obligations under Sections 4.03 through 4.16, inclusive, 4.19 and Article Five

SECTION 9.03. Conditions to Legal Defeasance or Covenant Defeasance.

              In order to exercise either Legal Defeasance pursuant to Section
9.02(b) or Covenant Defeasance pursuant to Section 9.02(c):

              (a) the Company must irrevocably deposit with the Trustee, in
       trust, for the benefit of the Holders, cash in U.S. dollars or United
       States Government Obligations, or a combination thereof, in such amounts
       as will be sufficient, in the opinion of a nationally recognized firm of
       independent public accountants, to pay the principal of, premium, if any,
       and interest on the Securities on the stated date for payment thereof or
       on the applicable redemption date, as the case may be;

              (b) in the case of an election under Section 9.02(b), the Company
       shall have delivered to the Trustee an Opinion of Counsel in the United
       States reasonably acceptable to the Trustee confirming that (A) the
       Company has received from, or there has been published by, the Internal
       Revenue Service a ruling or (B) since the date of this Indenture, there
       has been a change in the applicable federal income tax law, in either
       case to the effect that, and based thereon such Opinion of Counsel shall
       confirm that, the Holders of the Securities will not recognize income,
       gain or loss for federal income tax purposes as a result of such Legal
       Defeasance and will be subject to federal income tax on the same amounts,
       in the same manner and at the same times as would have been the case if
       such Legal Defeasance had not occurred;

              (c) in the case of an election under Section 9.02(c), the Company
       shall have delivered to the Trustee an Opinion of Counsel in the United
       States reasonably acceptable to the Trustee confirming that the Holders
       of the Securities will not recognize income, gain or loss for federal
       income tax purposes as a result of such Covenant Defeasance and will be
       subject to federal income tax on the same amounts, in the same manner and
       at the same times as would have been the case if such Covenant Defeasance
       had not occurred;

              (d) no Default or Event of Default shall have occurred and be
       continuing on the date of such deposit (other than a Default or Event of
       Default resulting from the borrowing of funds to be applied to such
       deposit) or insofar as Sections 6.01(f) and 6.01(g) are concerned, at any
       time in the period ending on the 91st day after the date of such deposit;

              (e) such Legal Defeasance or Covenant Defeasance shall not result
       in a breach or violation of or constitute a Default under this Indenture
       or any other material agreement or instrument to which the Company or any
       of its Restricted Subsidiaries is a party or by which the Company or any
       of its Restricted Subsidiaries is bound;

              (f) the Company shall have delivered to the Trustee an Officers'
       Certificate stating that the deposit was not made by the Company with the
       intent of preferring the Holders over any other creditors of the Company
       or with the intent of defeating, hindering, delaying or defrauding any
       other creditors of the Company or others;

              (g) the Company shall have delivered to the Trustee an Officers'
       Certificate and an Opinion of Counsel, each stating that all conditions
       precedent provided for or relating to the Legal Defeasance or the
       Covenant Defeasance have been complied with; and

<PAGE>   65

                                      -58-

              (h) the Company shall have delivered to the Trustee an Opinion of
       Counsel to the effect that assuming no intervening bankruptcy or
       insolvency of the Company between the date of deposit and the 91st day
       following the deposit and that no Holder is an insider of the Company,
       after the 91st day following the deposit, the trust funds will not be
       subject to the effect of any applicable bankruptcy, insolvency,
       reorganization or similar law affecting creditors' rights generally.

              Notwithstanding the foregoing, the Opinion of Counsel required by
clause (b) above need not be delivered if all Securities not theretofore
delivered to the Trustee for cancellation (x) have become due and payable, (y)
will become due and payable on the Final Maturity Date within one year or (z)
are to be called for redemption within one year under arrangements satisfactory
to the Trustee for the giving of notice of redemption by the Trustee in the
name, and at the expense, of the Company.

SECTION 9.04. Application of Trust Money; Trustee Acknowledgment and Indemnity.

              The Trustee shall hold in trust money or United States Government
Obligations deposited with it pursuant to Section 9.03, and shall apply the
deposited money and the money from United States Government Obligations in
accordance with this Indenture solely to the payment of principal of, premium,
if any, and interest on the Securities.

              After such delivery or irrevocable deposit and delivery of an
Officers' Certificate and Opinion of Counsel, the Trustee upon request shall
acknowledge in writing the discharge of the Company's obligations under the
Securities and this Indenture except for those surviving obligations specified
above.

              The Company shall pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the United States Government
Obligations deposited pursuant to Section 9.03 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of outstanding Securities.

SECTION 9.05. Repayment to Company.

              Subject to Sections 8.07 and 9.04, the Trustee shall promptly pay
to the Company upon written request any excess money held by it at any time. The
Trustee shall pay to the Company upon written request any money held by it for
the payment of principal or interest that remains unclaimed for two years;
provided, however, that the Trustee before being required to make any payment
may at the expense of the Company cause to be published once in a newspaper of
general circulation in The City of New York or mail to each Holder entitled to
such money notice that such money remains unclaimed and that, after a date
specified therein which shall be at least 30 days from the date of such
publication or mailing, any unclaimed balance of such money then remaining shall
be repaid to the Company. After payment to the Company, Holders entitled to
money must look solely to the Company for payment as general creditors unless an
applicable abandoned property law designates another person and all liability of
the Trustee or Paying Agent with respect to such money shall thereupon cease.

SECTION 9.06. Reinstatement.

              If the Trustee is unable to apply any money or United States
Government Obligations in accordance with Section 9.02 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's obligations under this Indenture and the Securities shall be revived
and reinstated as though no deposit 


<PAGE>   66

                                      -59-

had occurred pursuant to Section 9.02 until such time as the Trustee is
permitted to apply all such money or United States Government Obligations in
accordance with Section 9.02; provided, however, that if the Company has made
any payment of interest on or principal of any Securities because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money or
United States Government Obligations held by the Trustee.

              Subject to Section 6.07, the Company and the Guarantors, when
authorized by a Board Resolution, and the Trustee may modify, amend or
supplement, or waive compliance by the Company with any provision of, this

       Securities which may not be modified, amended, supplemented or waived
       without the consent of each Holder affected);

              (g) reduce the percentage of the principal amount of outstanding
       Securities necessary for amendment to or waiver of compliance with any
       provision of this Indenture or the Securities or for waiver of any
       Default in respect thereof;

              (h) waive a Default or Event of Default in the payment of
       principal of or premium, if any, or interest on the Securities (except a

       resulted from such acceleration);

              (i) waive a mandatory repurchase or redemption payment with

              After an amendment, supplement or waiver under this Section 10.02
becomes effective, the Company shall mail to the Holders affected thereby a

SECTION 10.03. Compliance with Trust Indenture Act.

              Every amendment to or supplement of this Indenture or the
Securities shall comply with the TIA as then in effect.

SECTION 10.04. Record Date for Consents and Effect of Consents.

              The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Holders of Securities entitled to consent to
any amendment, supplement or waiver. If a record date is fixed, then those
persons who were Holders of Securities at such record date (or their duly
designated proxies), and only those persons, shall be entitled to consent to
such amendment, supplement or waiver or to revoke any consent previously given,
whether or not such persons continue to be Holders of such Securities after such
record date. No such consent shall be valid or effective for more than 90 days
after such record date. The Trustee is entitled to rely upon any electronic
instruction from beneficial owners to the Holders of any Global Security.

              After an amendment, supplement or waiver becomes effective, it
shall bind every Holder, unless it makes a change described in any of clauses
(a) through (j) of Section 10.02. In that case the amendment, supplement or
waiver shall bind each Holder of a Security who has consented to it and every
subsequent Holder of a Security or portion of a Security that evidences the same

the changed terms and return it to the Holder. Alternatively, if the Company or
the Trustee so determine, the Company in exchange for the Security shall issue
and the Trustee shall authenticate a new Security that reflects the changed
terms. Failure to make the appropriate notation or issue a new Security shall
not affect the validity and effect of such amendment, supplement or waiver.

SECTION 10.06. Trustee To Sign Amendments, etc.

              The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
any amendment, supplement or waiver authorized pursuant to this Article Ten is
authorized or permitted by this Indenture and that such amendment, supplement or
waiver constitutes the legal, valid and binding obligation of the Company,
enforceable in accordance with its terms (subject to customary exceptions). The
Trustee may, but shall not be obligated to, execute any such amendment,
supplement or waiver which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise. In signing any amendment,
supplement or waiver, the Trustee shall be entitled to receive an indemnity
reasonably satisfactory to it.

                                 ARTICLE ELEVEN

                              SUBSIDIARY GUARANTEES


SECTION 11.01. Unconditional Guarantee.

              Each Guarantor hereby unconditionally, jointly and severally,
guarantees (each, a "Subsidiary Guarantee") to each Holder of a Security
authenticated by the Trustee and to the Trustee and its successors and assigns
that: the principal of and interest on the Securities will be promptly paid in
full when due, subject to any applicable grace period, whether at maturity, by
acceleration or otherwise, and interest on the overdue principal and interest on
any overdue interest on the Securities and all other obligations of the Company
to the Holders or the Trustee hereunder or under the Securities will be promptly
paid in full or performed, all in accordance with the terms hereof and thereof;
subject, however, to the limitations set forth in Section 11.04. Each Guarantor
hereby agrees that its obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Securities or
this Indenture, the absence of any action to enforce the same, any waiver or
consent by any Holder of the Securities with respect to any provisions hereof or
thereof, the recovery of any judgment against the Company, any action to enforce
the same or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a Guarantor. Each Guarantor hereby waives
diligence, presentment, demand of payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and covenants that the Subsidiary Guarantee will not be discharged except by
complete performance of the obligations contained in the Securities, this
Indenture and this Subsidiary Guarantee. If any Holder or the Trustee is
required by any court or otherwise to return to the Company, any Guarantor, or
any custodian, trustee, liquidator or other similar official acting in relation
to the Company or any Guarantor, any amount paid by the Company or any Guarantor
to the Trustee or such Holder, this Subsidiary Guarantee, to the extent
theretofore discharged, shall be reinstated in full force and effect. Each
Guarantor further agrees that, as between each Guarantor, on the one hand, and
the Holders and the Trustee, on the other hand, (x) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Six for
the purpose of this Subsidiary Guarantee, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any acceleration of such obligations
as provided in Article Six, such obligations (whether or not due and payable)
shall forth become due and payable by each Guarantor for the purpose of this
Subsidiary Guarantee.

SECTION 11.02. Severability.

              In case any provision of this Subsidiary Guarantee shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 11.03. Release of a Guarantor.

              (a) If the Securities are defeased in accordance with the terms of
this Indenture, or if Section 5.01(b) is complied with, or if, subject to the
requirements of Section 5.01(a), all or substantially all of the assets of any
Guarantor or all of the equity interests of any Guarantor are sold (including by
issuance or otherwise) by the Company in a transaction constituting an Asset
Sale and (x) the Net Cash Proceeds from such Asset Sale are used in accordance
with Section 

<PAGE>   70

                                      -63-

4.08 or (y) the Company delivers to the Trustee an Officers' Certificate to the
effect that the Net Cash Proceeds from such Asset Sale shall be used in
accordance with Section 4.08 and within the time limits specified by Section
4.08, then each Guarantor (in the case of defeasance) or such Guarantor (in the
case of compliance with Section 5.01(b) or in the event of a sale or other
disposition of all of the equity interests of such Guarantor) or the Person
acquiring such assets (in the event of a sale or other disposition of all or
substantially all of the assets of such Guarantor) shall be released and
discharged from all obligations under this Article Eleven without any further
action required on the part of the Trustee or any Holder. The Trustee shall, at
the sole cost and expense of the Company and upon receipt at the reasonable
request of the Trustee of an Opinion of Counsel that the provisions of this
Section 11.03 have been complied with, deliver an appropriate instrument
evidencing such release upon receipt of a request by the Company accompanied by
an Officers' Certificate certifying as to the compliance with this Section
11.03. Any Guarantor not so released remains liable for the full amount of
principal of and interest on the Securities and the other obligations of the
Company hereunder as provided in this Article Eleven.

              (b) Any Guarantor that is designated an Unrestricted Subsidiary
shall upon such designation be released and discharged of all obligations under
this Article Eleven without any further action required on the part of the
Trustee or any Holder.

SECTION 11.04. Limitation of Guarantor's Liability.

              Each Guarantor, and by its acceptance hereof each Holder and the
Trustee, hereby confirms that it is the intention of all such parties that the
Guarantee by such Guarantor pursuant to its Subsidiary Guarantee not constitute
a fraudulent transfer or conveyance for purposes of title 11 of the United
States Code, as amended, the Uniform Fraudulent Conveyance Act, the Uniform
Fraudulent Transfer Act or any similar U.S. Federal or state or other applicable
law. To effectuate the foregoing intention, the Holders and each Guarantor
hereby irrevocably agree that the obligations of each Guarantor under its
Subsidiary Guarantee shall be limited to the maximum amount as will, after
giving effect to all other contingent and fixed liabilities of such Guarantor
and after giving effect to any collections from or payments made by or on behalf
of any other Guarantor in respect of the obligations of such other Guarantor
under its Subsidiary Guarantee or pursuant to Section 11.05, result in the
obligations of such Guarantor under its Subsidiary Guarantee not constituting
such a fraudulent transfer or conveyance.

SECTION 11.05. Contribution.

              In order to provide for just and equitable contribution among the
Guarantors, the Guarantors agree, inter se, that in the event any payment or
distribution is made by any Guarantor (a "Funding Guarantor") under the
Subsidiary Guarantee, such Funding Guarantor shall be entitled to a contribution
from all other Guarantors in a pro rata amount, based on the net assets of each
Guarantor (including the Funding Guarantor), determined in accordance with GAAP,
subject to Section 11.04, for all payments, damages and expenses incurred by
such Funding Guarantor in discharging the Company's obligations with respect to
the Securities or any other Guarantor's obligations with respect to the
Subsidiary Guarantee.

SECTION 11.06. Execution of Subsidiary Guarantee.

              To further evidence their Guarantee to the Holders, each of the
Guarantors hereby agree to execute a Subsidiary Guarantee to be endorsed on each
Security ordered to be authenticated and delivered by the Trustee. Each
Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 11.01
shall remain in full force and effect notwithstanding any failure to endorse on
each Security a Subsidiary Guarantee. Each such Subsidiary Guarantee shall be
signed on behalf of each Guarantor by its Chairman of the Board, its President
or one of its Vice Presidents prior to the authentication of the Security on
which it is endorsed, and 


<PAGE>   71

                                      -64-

the delivery of such Security by the Trustee, after the authentication thereof
hereunder, shall constitute due delivery of such Subsidiary Guarantee on behalf
of such Guarantor. Such signature upon the Subsidiary Guarantee may be manual or
facsimile signature of such officer and may be imprinted or otherwise reproduced
on the Subsidiary Guarantee, and in case such officer who shall have signed the
Subsidiary Guarantee shall cease to be such officer before the Security on which
such Subsidiary Guarantee is endorsed shall have been authenticated and
delivered by the Trustee or disposed of by the Company, such Security
nevertheless may be authenticated and delivered or disposed of as though the
Person who signed the Subsidiary Guarantee had not ceased to be such officer of
such Guarantor.

SECTION 11.07. Subordination of Subrogation and Other Rights.

              Each Guarantor hereby agrees that any claim against the Company
that arises from the payment, performance or enforcement of such Guarantor's
obligations under its Subsidiary Guarantee or this Indenture, including, without
limitation, any right of subrogation, shall be subject and subordinate to, and
no payment with respect to any such claim of such Guarantor shall be made
before, the payment in full in cash of all outstanding Securities in accordance
with the provisions provided therefor in this Indenture.


                                 ARTICLE TWELVE

                      SUBORDINATION OF SUBSIDIARY GUARANTEE


SECTION 12.01. Agreement To Subordinate.

              Each Guarantor agrees, and each Holder by accepting a Subsidiary
Guarantee agrees, that the Indebtedness of such Guarantor evidenced by the
Subsidiary Guarantee is subordinated in right of payment, to the extent and in
the manner provided in this Article Twelve, to the payment when due of all
Guarantor Senior Indebtedness of such Guarantor and that such subordination is
for the benefit of and enforceable by the holders of Guarantor Senior
Indebtedness. The Subsidiary Guarantee shall in all respects rank pari passu
with all other Guarantor Senior Subordinated Indebtedness of a Guarantor, and
only Indebtedness of a Guarantor which is Guarantor Senior Indebtedness will
rank senior to the Subsidiary Guarantee in accordance with the provisions set
forth herein. Unsecured Indebtedness is not deemed to be subordinate or junior
to Secured Indebtedness merely because it is unsecured, nor is any Indebtedness
deemed to be subordinate or junior to other Indebtedness merely because it
matures after such other Indebtedness. Secured Indebtedness is not deemed to be
Senior Indebtedness merely because it is secured. All provisions of this Article
Twelve shall be subject to Section 12.12.

SECTION 12.02. Liquidation, Dissolution, Bankruptcy.

              Upon any payment or distribution of the assets of a Guarantor upon
a total or partial liquidation or dissolution or reorganization or bankruptcy of
or similar proceeding relating to a Guarantor or its property:

              (1)   holders of Guarantor Senior Indebtedness of such Guarantor
       shall be entitled to receive payment in full in cash or Cash Equivalents
       of all Guarantor Senior Indebtedness of such Guarantor before Holders
       shall be entitled to receive any payment of principal of or interest on
       or other amounts with respect to the Securities from such Guarantor; and



<PAGE>   72

                                      -65-

              (2)   until the Guarantor Senior Indebtedness of such Guarantor is
       paid in full, any payment or distribution to which Holders would be
       entitled but for the provisions of this Article Twelve shall be made to
       holders of Guarantor Senior Indebtedness as their interests may appear.

SECTION 12.03. Default on Guarantor Senior Indebtedness.

              No Guarantor may pay the principal of, premium (if any), or
interest on, and other obligations with respect to, the Securities or make any
deposit pursuant to Section 9.03 or repurchase, redeem or otherwise retire any
Securities (collectively, "pay the Securities") if (i) any Guarantor Senior
Indebtedness is not paid in cash or Cash Equivalents when due or (ii) any other
default on Guarantor Senior Indebtedness occurs and the maturity of such
Guarantor Senior Indebtedness is accelerated in accordance with its terms
unless, in either case, (x) the default has been cured or waived or is no longer
continuing and/or any such acceleration has been rescinded or (y) such Guarantor
Senior Indebtedness has been paid in full; provided, however, that the Guarantor
may pay the Securities subject to the provisions of Section 12.02, without
regard to the foregoing if the Guarantor and the Trustee receive written notice
approving such payment from the Representatives of the Senior Indebtedness with
respect to which either of the events set forth in clause (i) or (ii) of this
sentence has occurred or is continuing. During the continuance of any default
(other than a default described in clause (i) or (ii) of the preceding sentence)
with respect to any Designated Senior Indebtedness pursuant to which the
maturity thereof may be accelerated immediately without further notice (except
such notice as may be required to effect such acceleration) or the expiration of
any applicable grace periods, a Guarantor may not pay the Securities (except (i)
in Qualified Capital Stock issued by such Guarantor to pay interest on the
Securities or issued in exchange for the Securities, (ii) in securities
substantially identical to the Securities issued by such Guarantor in payment of
interest accrued thereon or (iii) in securities issued by such Guarantor which
are subordinated to the Guarantor Senior Indebtedness at least to the same
extent as the Securities and having a Weighted Average Life to Maturity at least
equal to the remaining Weighted Average Life to Maturity of the Securities) for
a period (a "Guarantor Payment Blockage Period") commencing upon the receipt by
the Trustee (with a copy to the Guarantor) of written notice (a "Guarantor
Blockage Notice") of such default from the Representative of the holders of such
Designated Senior Indebtedness specifying an election to effect a Guarantor
Payment Blockage Period and ending 179 days thereafter (or earlier if such
Guarantor Payment Blockage Period is terminated (i) by written notice to the
Trustee and the Guarantor from the Person or Persons who gave such Guarantor
Blockage Notice, (ii) because the default giving rise to such Guarantor Blockage
Notice is no longer continuing) or (iii) because such Designated Senior
Indebtedness has been repaid in full. Notwithstanding the provisions of the
immediately preceding sentence, but subject to the provisions of the first
sentence of this Section 12.03 and the provisions of Section 12.02, the
Guarantor may resume payments on the Securities after the end of such Payment
Blockage Period. Not more than one Blockage Notice may be given, and not more
than one Payment Blockage Period may occur, in any consecutive 360-day period,
irrespective of the number of defaults with respect to Designated Senior
Indebtedness during such period. However, if any Blockage Notice within such
360-day period is given by or on behalf of any holders of Designated Senior
Indebtedness (other than the agent under the Senior Credit Facilities), the
agent under the Senior Credit Facilities may give another Blockage Notice within
such period. In no event, however, may the total number of days during which any
Payment Blockage Period or Payment Blockage Periods are in effect exceed 179
days in the aggregate during any 360 consecutive day period. No nonpayment
default that existed or was continuing on the date of delivery of any Blockage
Notice to the Trustee shall be, or be made, the basis for a subsequent Blockage
Notice unless such default shall have been cured or waived for a period of not
less than 90 consecutive days.

SECTION 12.04. Acceleration of Payment of Securities.

              If a notice is required pursuant to the first sentence of Section
7.04, no Guarantor may pay the Securities (except payment (i) in Qualified
Capital Stock issued by the Guarantor to pay interest on the Securities or
issued in exchange for the Securities, (ii) in securities substantially
identical to the Securities issued by the Guarantor in payment of interest
accrued thereon or (iii) securities issued by the Guarantor which are
subordinated to the Guarantor Senior Indebtedness at least to the same extent as
the Securities and have a Weighted Average Life to Maturity at least equal to
the remaining Weighted Average Life to Maturity of the Securities), until five
Business Days after the respective Representative of the Designated Senior
Indebtedness receives notice (at the address specified in the preceding
sentence) of such acceleration and thereafter, may pay the Securities only if
the provisions of this Article Twelve otherwise permit payment at that time.
SECTION 12.05. When Distribution Must Be Paid Over.

              If a distribution is made to the Trustee or to Holders that
because of this Article Twelve should not have been made to them, the Trustee or
the Holders who receive such distribution shall hold it in trust for holders of
Guarantor Senior Indebtedness and promptly pay it over to them as their
respective interests may appear; provided, however, that the liabilities of the
Trustee under this Section 12.05 are limited by Section 12.15.

SECTION 12.06. Subrogation.

              After all Guarantor Senior Indebtedness is paid in full and until
the Securities are paid in full, Holders shall be subrogated to the rights of
holders of Guarantor Senior Indebtedness to receive distributions applicable to
Guarantor Senior Indebtedness. A distribution made under this Article Twelve to
holders of Guarantor Senior Indebtedness which otherwise would have been made to
Holders is not, as between the Guarantor and the Holders, a payment by any
Guarantor of Guarantor Senior Indebtedness.

SECTION 12.07. Relative Rights.

              This Article Twelve defines the relative rights of Holders of the
Securities on the one hand and holders of Guarantor Senior Indebtedness on the
other hand. Nothing in this Indenture shall:

              (a) impair, as between the Guarantor and the Holders, the
       obligations of any Guarantor, which are absolute and unconditional, in
       respect of its Subsidiary Guarantee; or

              (b) prevent the Trustee or any Holder from exercising its
       available remedies upon a Default or Event of Default, subject to the
       rights of holders of Guarantor Senior Indebtedness to receive
       distributions otherwise payable to Holders.

SECTION 12.08. Subordination May Not Be Impaired by Guarantor.

              No right of any holder of Guarantor Senior Indebtedness to enforce
the subordination of the obligations under any Subsidiary Guarantee evidenced by
the Securities shall be impaired by any act or failure to act by any Guarantor
or by the failure of any Guarantor to comply with this Indenture.

<PAGE>   74

                                      -67-

SECTION 12.09. Rights of Trustee and Paying Agent.

              Notwithstanding Section 12.03, the Trustee or Paying Agent may
continue to make payments on the Securities and shall not be charged with
knowledge of the existence of facts that would prohibit the making of any such
payments unless, not less than two Business Days prior to the date of such
payment, a Trust Officer of the Trustee receives notice satisfactory to it that
payments may not be made under this Article Twelve. A Guarantor, the Registrar
or co-registrar, the Paying Agent, a Representative or a holder of Guarantor
Senior Indebtedness may give the notice; provided, however, that if an issue of
Guarantor Senior Indebtedness has a Representative, only the Representative may
give the notice.

              The Trustee in its individual or any other capacity may hold
Guarantor Senior Indebtedness with the same rights it would have if it were not
Trustee. The Registrar and co-registrar and the Paying Agent may do the same
with like rights. The Trustee shall be entitled to all the rights set forth in
this Article Twelve with respect to any Guarantor Senior Indebtedness which may
at any time be held by it, to the same extent as any other holder of Guarantor
Senior Indebtedness; and nothing in Article Twelve shall deprive the Trustee of
any of its rights as such holder. Nothing in this Article Twelve shall apply to
claims of, or payments to, the Trustee under or pursuant to Section 8.07.

SECTION 12.10. Distribution or Notice to Representative.

              Whenever a distribution is to be made or a notice given to holders
of Guarantor Senior Indebtedness, the distribution may be made and the notice
given to their Representative, if any.

SECTION 12.11. Article Twelve Not To Prevent Events of Default or Limit Right To
               Accelerate.

              The failure to make a payment in respect of the Securities by
reason of any provision in this Article Twelve shall not be construed as
preventing the occurrence of a Default or Event of Default. Nothing in this
Article Twelve shall have any effect on the right of the Holders or the Trustee
to enforce any Subsidiary Guarantee or to accelerate the maturity of the
Securities.

SECTION 12.12. Trust Moneys Not Subordinated.

              Notwithstanding anything contained herein to the contrary,
payments from money or the proceeds of U.S. Government Obligations held in trust
under Article Eight by the Trustee for payment in respect of the Subsidiary
Guarantees shall not be subordinated to the prior payment of any Guarantor
Senior Indebtedness or subject to the restrictions set forth in this Article
Twelve, and none of the Holders shall be obligated to pay over any such amount
to such Guarantor, any holder of Guarantor Senior Indebtedness of such
Guarantor, or any other creditor of such Guarantor.

SECTION 12.13. Trustee Entitled To Rely.

              Upon any payment or distribution pursuant to this Article Twelve,
the Trustee and the Holders shall be entitled to rely (i) upon any order or
decree of a court of competent jurisdiction in which any proceedings of the
nature referred to in Section 12.02 are pending, (ii) upon a certificate of the
liquidating trustee or agent or other Person making such payment or distribution
to the Trustee or to the Holders or (iii) upon the Representatives for the
holders of Guarantor Senior Indebtedness for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of
Guarantor Senior Indebtedness and other Indebtedness of any Guarantor, the
amount thereof or payable thereon, the amount or amounts paid or distrib-

<PAGE>   75

                                      -68-

uted thereon and all other facts pertinent thereto or to this Article Twelve. In
the event that the Trustee determines, in good faith, that evidence is required
with respect to the right of any Person as a holder of Guarantor Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article Twelve, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Guarantor Senior
Indebtedness held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and other facts pertinent to the
rights of such Person under this Article Twelve, 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. The
Trustee shall have the right to seek a declaratory judgment as to any right of
such Person to receive such payment. The provisions of Sections 8.01 and 8.02
shall be applicable to all actions or omissions of actions by the Trustee
pursuant to this Article Twelve.

SECTION 12.14. Trustee To Effectuate Subordination.

              Each Holder by accepting a Subsidiary Guarantee authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to acknowledge or effectuate the subordination between the Holder
and the holders of Guarantor Senior Indebtedness as provided in this Article
Twelve and appoints the Trustee as attorney-in-fact for any and all such
purposes.

SECTION 12.15. Trustee Not Fiduciary for Holders of Guarantor Senior
               Indebtedness.

              The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Guarantor Senior Indebtedness and shall not be liable to any such
holders if it shall mistakenly pay over or distribute to Holders or the
Guarantor, or any other Person, money or assets to which any holders of
Guarantor Senior Indebtedness shall be entitled by virtue of this Article Twelve
or otherwise.

SECTION 12.16. Reliance by Holders of Guarantor Senior Indebtedness on
               Subordination Provisions.

              Each Holder by accepting a Subsidiary Guarantee acknowledges and
agrees that the foregoing subordination provisions are, and are intended to be,
an inducement and a consideration to each holder of any Guarantor Senior
Indebtedness, whether such Guarantor Senior Indebtedness was created or acquired
before or after the issuance of the Subsidiary Guarantee, to acquire and
continue to hold, or to continue to hold, such Guarantor Senior Indebtedness and
such holder of Guarantor Senior Indebtedness shall be deemed conclusively to
have relied on such subordination provisions in acquiring and continuing to
hold, or in continuing to hold, such Guarantor Senior Indebtedness.


                                ARTICLE THIRTEEN

Guarantees, as the case may be, or this Indenture or for any claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder by

                    8 3/8% Senior Subordinated Note due 2008



1.   Interest.

              LIN ACQUISITION COMPANY promises to pay interest on the principal
amount of this Security at the rate per annum shown above. Cash interest on the
Securities will accrue from the most recent date to which interest has been paid
or, if no interest has been paid, from March 3, 1998. The Company will pay
interest semi-annually in arrears on each Interest Payment Date, commencing on
September 1, 1998. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

              The Company shall pay interest on overdue principal from time to
time on demand and on overdue installments of interest (without regard to any
applicable grace periods) to the extent lawful from time to time on demand, in
each case at the rate borne by the Securities.

2.   Method of Payment.

              The Company shall pay interest on the Securities (except defaulted
interest) to the persons who are the registered Holders at the close of business
on the Interest Record Date immediately preceding the Interest Payment Date even
if the Securities are canceled on registration of transfer or registration of
exchange after such Interest Record Date. Holders must surrender Securities to a
Paying Agent to collect principal payments. The Company shall pay principal and
interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts ("U.S. Legal Tender"). However,
the Company may pay principal and interest by wire transfer of Federal funds
(provided that the Paying Agent shall have received wire instructions on or
prior to the relevant Interest Record Date), or interest by check payable in
such U.S. Legal Tender. The Company may deliver any such interest payment to the
Paying Agent or to a Holder at the Holder's registered address.

3.   Paying Agent and Registrar.

              Initially, United States Trust Company of New York (the "Trustee")
will act as Paying Agent and Registrar. The Company may change any Paying Agent
or Registrar without notice to the Holders. The Company may, subject to certain
exceptions, act as Registrar.

4.   Indenture.

              The Company issued the Securities under an Indenture, dated as of
March 3, 1998 (the "Indenture"), by and among the Company, the Guarantors named
therein and the Trustee. Capitalized terms herein are used as defined in the
Indenture unless otherwise defined herein. This Security is one of a duly
authorized issue of Securities of the Company designated as its 8 3/8% Senior
Subordinated Notes due 2008, Series A (the "Initial Securities"), limited in
aggregate principal amount to $300,000,000, which may be issued under the
Indenture. The Securities include the Initial Securities, the Private Exchange
Securities (as defined in the Indenture) and the Unrestricted Securities (as
defined in the Indenture). All Securities issued under the 


                                      A-4
<PAGE>   86


Indenture are treated as a single class of securities under the Indenture. The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
ss.ss. 77aaa-77bbbb) (the "TIA"), as in effect on the date of the Indenture
(except as otherwise indicated in the Indenture) until such time as the
Indenture is qualified under the TIA, and thereafter as in effect on the date on
which the Indenture is qualified under the TIA. Notwithstanding anything to the
contrary herein, the Securities are subject to all such terms, and Holders are
referred to the Indenture and the TIA for a statement of them. The Securities
are general unsecured obligations of the Company. The Securities are
subordinated in right of payment to all existing and future Senior Indebtedness
of the Company to the extent and in the manner provided in the Indenture. Each
Holder of a Security, by accepting a Security, agrees to such subordination,
authorizes the Trustee to give effect to such subordination and appoints the
Trustee as attorney-in-fact for such purpose.

5.   Optional Redemption.

              (a) The Securities will be redeemable at the option of the
Company, in whole or in part, at any time on or after March 1, 2003, at the
redemption prices (expressed as a percentage of principal amount) set forth
below, plus accrued and unpaid interest thereon, if any, to the Redemption Date
(subject to the right of Holders of record on the relevant Interest Record Date
to receive interest due on the relevant Interest Payment Date) if redeemed
during the 12-month period commencing on March 1 of the years indicated below:

                         <S>                       <C>
                         2003                      104.188%
                         2004                      102.792%

                         2006 and thereafter       100.000%
</TABLE>


              (b) Prior to March 1, 2001, the Company may, at its option, use
the net cash proceeds of one or more Equity Offerings to redeem up to 35% of the
principal amount of the Securities at a redemption price equal to 108.375% of
the principal amount thereof plus accrued and unpaid interest to the redemption
date; provided, however, that after any such redemption, at least 65% of the
aggregate principal amount of the Securities originally issued would remain
outstanding immediately after giving effect to such redemption. Any such
redemption will be required to occur on or prior to the date that is one year
after the receipt by the Company of the proceeds of an Equity Offering. The
Company shall effect such redemption on a pro rata basis.

              (c) Prior to March 1, 2003, upon the occurrence of a Change of
Control, the Company will have the option to redeem the Securities in whole but
not in part (a "Change of Control Redemption") at a redemption price equal to
100% of the principal amount thereof, plus accrued and unpaid interest to the
redemption date, plus the Applicable Premium. In order to effect a Change of
Control Redemption, the Company must send a notice to each Holder, which notice
shall govern the terms of the Change of Control Redemption. Such notice must
comply with the provisions of Section 3.03 of the Indenture; provided, however,
that such notice must be mailed to Holders within 30 days following the date the
Change of Control occurred (the "Change of Control Redemption Date") and state
that the Company is effecting a Change of Control Redemption in lieu of a Change
of Control Offer.

              "Applicable Premium" means, with respect to a Security at any
Change of Control Redemption Date, the greater of (i) 1.0% of the principal
amount of such Security and (ii) the excess of (A) the present value at such
time of (1) the redemption price of such Security at March 1, 2003 (such
redemption price being described in paragraph (a) above) plus (2) all
semi-annual payments of interest through March 1, 2003 com-


                                      A-5
<PAGE>   87

puted using a discount rate equal to the Treasury Rate plus 75 basis points over
(B) the principal amount of such Security.

              "Treasury Rate" means the yield to maturity at the time of
computation of United States Treasury Securities with a constant maturity (as
compiled and published in the most recent Federal Reserve Statistical Release
H.15(519) that has become publicly available at least two business days prior to
the Change of Control Redemption Date (or, if such Statistical Release is no
longer published, any publicly available source of similar market data)) most
nearly equal to the period from the Change of Control Redemption Date to March
1, 2003; provided, however, that if the period from the Change of Control
Redemption Date to March 1, 2003 is not equal to the constant maturity of a
United States Treasury security for which a weekly average yield is given, the
Treasury Rate shall be obtained by linear interpolation (calculated to the
nearest one-twelfth of a year) from the weekly average yields of United States
Treasury Securities for which such yields are given except that if the period
from the Change of Control Redemption Date to March 1, 2003 is less than one
year, the weekly average yield on actually traded United States Treasury
Securities adjusted to a constant maturity of one year shall be used.

6.   Notice of Redemption.

              Notice of redemption will be mailed by first-class mail at least
30 days but not more than 60 days before the Redemption Date to each Holder of
Securities to be redeemed at its registered address. The Trustee may select for
redemption portions of the principal amount of Securities that have
denominations equal to or larger than $1,000 principal amount. Securities and
portions of them the Trustee so selects shall be in amounts of $1,000 principal
amount or integral multiples thereof.

              If any Security is to be redeemed in part only, the notice of
redemption that relates to such Security shall state the portion of the
principal amount thereof to be redeemed. A new Security in a principal amount
equal to the unredeemed portion thereof will be issued in the name of the Holder
thereof upon cancellation of the original Security. On and after the Redemption
Date, interest will cease to accrue on Securities or portions thereof called for
redemption so long as the Company has deposited with the Paying Agent for the
Securities funds in satisfaction of the redemption price pursuant to the
Indenture and the Paying Agent is not prohibited from paying such funds to the
Holders pursuant to the terms of the Indenture.

7.   Change of Control Offer.

              Following the occurrence of a Change of Control (the date of such
occurrence being the "Change of Control Date"), the Company shall, within 30
days after the Change of Control Date, be required to offer to purchase all
Securities then outstanding at a purchase price in cash equal to 101% of the

9.   Denominations; Transfer; Exchange.

              The Securities are in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000. A Holder shall
register the transfer of or exchange Securities in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay certain transfer
taxes or similar governmental charges payable in connection therewith as
permitted by the Indenture. The Registrar need not register the transfer of or
exchange any Securities or portions thereof selected for redemption, except the
unredeemed portion of any security being redeemed in part.

10.  Persons Deemed Owners.

              The registered Holder of a Security shall be treated as the owner
of it for all purposes.

11.  Unclaimed Funds.

              If funds for the payment of principal or interest remain unclaimed
for two years, the Trustee and the Paying Agent will repay the funds to the
Company at their written request. After that, all liability of the Trustee and
such Paying Agent with respect to such funds shall cease.

12.  Legal Defeasance and Covenant Defeasance.

              The Company and the Guarantors may be discharged from their
obligations under the Indenture, the Securities and the Subsidiary Guarantees,
except for certain provisions thereof, and may be discharged from obligations to
comply with certain covenants contained in the Indenture, the Securities and the
Subsidiary Guarantees, in each case upon satisfaction of certain conditions
specified in the Indenture.

13.  Amendment; Supplement; Waiver.

              Subject to certain exceptions, the Indenture and the Securities
(including the Subsidiary Guarantees) may be amended or supplemented with the
written consent of the Holders of at least a majority in aggregate principal
amount of the Securities then outstanding, and any existing Default or Event of
Default or compliance with any provision may be waived with the consent of the
Holders of a majority in aggregate principal amount of the Securities then
outstanding. Without notice to or consent of any Holder, the parties thereto may
amend or supplement the Indenture, the Securities and the Subsidiary Guarantees
to, among other things, cure any ambiguity, defect or inconsistency, provide for
uncertificated Securities in addition to or in place of certificated Securities
or comply with any requirements of the SEC in connection with the qualification
of the Indenture under the TIA, or make any other change that does not
materially adversely affect the rights of any Holder.

14.  Restrictive Covenants.

              The Indenture contains certain covenants that, among other things,
limit the ability of the Company and the Restricted Subsidiaries to make
restricted payments, to incur indebtedness, to sell assets, to permit
restrictions on dividends and other payments by Subsidiaries to the Company, to
consolidate, merge or sell all or substantially all of its assets and to engage
in transactions with affiliates. The limitations are subject to a number of
important qualifications and exceptions. The Company must report annually to the
Trustee on compliance with such limitations.

<PAGE>   89


15.  Defaults and Remedies.

              If an Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in aggregate principal amount of Securities then
outstanding may declare all the Securities to be due and payable immediately in
the manner and with the effect provided in the Indenture. Holders of Securities
may not enforce the Indenture, the Securities or the Subsidiary Guarantees
except as provided in the Indenture. The Trustee is not obligated to enforce the
Indenture, the Securities or the Subsidiary Guarantees unless it has received
indemnity satisfactory to it. The Indenture permits, subject to certain
limitations therein provided, Holders of a majority in aggregate principal
amount of the Securities then outstanding to direct the Trustee in its exercise
of any trust or power. The Trustee may withhold from Holders of Securities
notice of certain continuing Defaults or Events of Default if it determines that
withholding notice is in their interest.

16.  Trustee Dealings with Company and Guarantors.

              The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities and may otherwise deal
with the Company, the Guarantors, their respective Subsidiaries or their
respective Affiliates as if it were not the Trustee.

17.  No Recourse Against Others.

              No director, officer, employee, incorporator or stockholder of the
Company or any Guarantor, as such, shall have any liability for any obligations
of the Company or any Guarantor under the Securities or the Subsidiary
Guarantees, as the case may be, or the Indenture or for any claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder by
accepting a Security waives and releases all such liability. The waiver and
release are part of the consideration for the issuance of the Securities and the
Subsidiary Guarantees.

18.  Authentication.

              This Security shall not be valid until the Trustee or
authenticating agent signs the certificate of authentication on this Security.

19.  Abbreviations and Defined Terms.

              Customary abbreviations may be used in the name of a Holder of a
Security or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian) and U/G/M/A (= Uniform Gifts
to Minors Act).

20.  CUSIP Numbers.

              Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company has caused CUSIP numbers
to be printed on the Securities as a convenience to the Holders of the
Securities. No representation is made as to the accuracy of such numbers as
printed on the Securities and reliance may be placed only on the other
identification numbers printed hereon.

21.  Registration Rights.

              Pursuant to the Registration Rights Agreement, the Company and the
Guarantors will be obligated to consummate an exchange offer pursuant to which
the Holder of this Security shall have the right to exchange this Security for a
8 3/8% Senior Subordinated Note due 2008 of the Company which has been
registered under the Securities Act, in like principal amount and having terms
identical in all material respects to the Initial Securities. The Holders shall
be entitled to receive certain liquidated damages payments in the event such
exchange offer is not consummated and upon certain other conditions, all
pursuant to and in accordance with the terms of the Registration Rights
Agreement.

22.  Governing Law.

              The laws of the State of New York shall govern the Indenture, this
Security and any Guarantee hereof without regard to principles of conflicts of
laws to the extent that the application of the laws of another jurisdiction
would be required thereby.

               8 3/8% Senior Subordinated Note due 2008, Series B



1.   Interest.

              LIN ACQUISITION COMPANY promises to pay interest on the principal
amount of this Security at the rate per annum shown above. Cash interest on the
Securities will accrue from the most recent date to which interest has been paid
or, if no interest has been paid, from March 3, 1998. The Company will pay
interest semi-annually in arrears on each Interest Payment Date, commencing on
September 1, 1998. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

              The Company shall pay interest on overdue principal from time to
time on demand and on overdue installments of interest (without regard to any
applicable grace periods) to the extent lawful from time to time on demand, in
each case at the rate borne by the Securities.

2.   Method of Payment.

              The Company shall pay interest on the Securities (except defaulted
interest) to the persons who are the registered Holders at the close of business
on the Interest Record Date immediately preceding the Interest Payment Date even
if the Securities are canceled on registration of transfer or registration of
exchange after such Interest Record Date. Holders must surrender Securities to a
Paying Agent to collect principal payments. The Company shall pay principal and
interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts ("U.S. Legal Tender"). However,
the Company may pay principal and interest by wire transfer of Federal funds
(provided that the Paying Agent shall have received wire instructions on or
prior to the relevant Interest Record Date), or interest by check payable in
such U.S. Legal Tender. The Company may deliver any such interest payment to the
Paying Agent or to a Holder at the Holder's registered address.

3.   Paying Agent and Registrar.

              Initially, United States Trust Company of New York (the "Trustee")
will act as Paying Agent and Registrar. The Company may change any Paying Agent
or Registrar without notice to the Holders. The Company may, subject to certain
exceptions, act as Registrar.

4.   Indenture.

              The Company issued the Securities under an Indenture, dated as of
March 3, 1998 (the "Indenture"), by and among the Company, the Guarantors named
therein and the Trustee. Capitalized terms herein are used as defined in the
Indenture unless otherwise defined herein. This Security is one of a duly
authorized issue of Securities of the Company designated as its 8 3/8% Senior
Subordinated Notes due 2008, Series B limited in aggregate principal amount to
$300,000,000, which may be issued under the Indenture. The Securities include
the Initial Securities (as defined in the Indenture), the Private Exchange
Securities (as defined in the Indenture) and the Unrestricted Securities (as
defined in the Indenture). All Securities issued 


                                      B-3
<PAGE>   98


under the Indenture are treated as a single class of securities under the
Indenture. The terms of the Securities include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S.C. ss.ss. 77aaa-77bbbb) (the "TIA"), as in effect on the date of the
Indenture (except as otherwise indicated in the Indenture) until such time as
the Indenture is qualified under the TIA, and thereafter as in effect on the
date on which the Indenture is qualified under the TIA. Notwithstanding anything
to the contrary herein, the Securities are subject to all such terms, and
Holders are referred to the Indenture and the TIA for a statement of them. The
Securities are general unsecured obligations of the Company. The Securities are
subordinated in right of payment to all existing and future Senior Indebtedness
of the Company to the extent and in the manner provided in the Indenture. Each
Holder, by accepting a Security, agrees to such subordination, authorizes the
Trustee to give effect to such subordination and appoints the Trustee as
attorney-in-fact for such purpose.

5.   Optional Redemption.

              (a) The Securities will be redeemable at the option of the
Company, in whole or in part, at any time on or after March 1, 2003, at the
redemption prices (expressed as a percentage of principal amount) set forth
below, plus accrued and unpaid interest thereon, if any, to the Redemption Date
(subject to the right of Holders of record on the relevant Interest Record Date
to receive interest due on the relevant Interest Payment Date) if redeemed
during the 12-month period commencing on March 1 of the years indicated below:

Year                                                 Percentage

<S>                                                   <C>     
2003                                                  104.188%
2004                                                  102.792%
2005                                                  101.396%
2006 and thereafter                                   100.000%
</TABLE>

              (b) Prior to March 1, 2001, the Company may, at its option, use
the net cash proceeds of one or more Equity Offerings to redeem up to 35% of the
principal amount of the Securities at a redemption price equal to 108.375% of
the principal amount thereof plus accrued and unpaid interest to the redemption
date; provided, however, that after any such redemption, at least 65% of the
aggregate principal amount of the Securities originally issued would remain
outstanding immediately after giving effect to such redemption. Any such
redemption will be required to occur on or prior to the date that is one year
after the receipt by the Company of the proceeds of an Equity Offering. The
Company shall effect such redemption on a pro rata basis.

              (c) Prior to March 1, 2003, upon the occurrence of a Change of
Control, the Company will have the option to redeem the Securities in whole but
not in part (a "Change of Control Redemption") at a redemption price equal to
100% of the principal amount thereof, plus accrued and unpaid interest to the
redemption date, plus the Applicable Premium. In order to effect a Change of
Control Redemption, the Company must send a notice to each Holder, which notice
shall govern the terms of the Change of Control Redemption. Such notice must
comply with the provisions of Section 3.03 of the Indenture; provided, however,
that such notice must be mailed to Holders within 30 days following the date the
Change of Control occurred (the "Change of Control Redemption Date") and state
that the Company is effecting a Change of Control Redemption in lieu of a Change
of Control Offer.

              "Applicable Premium" means, with respect to a Security at any
Change of Control Redemption Date, the greater of (i) 1.0% of the principal
amount of such Security and (ii) the excess of (A) the present value at such
time of (1) the redemption price of such Security at March 1, 2003 (such
redemption price being described in paragraph (a) above) plus (2) all
semi-annual payments of interest through March 1, 2003 com-

puted using a discount rate equal to the Treasury Rate plus 75 basis points over
(B) the principal amount of such Security.

              "Treasury Rate" means the yield to maturity at the time of
computation of United States Treasury Securities with a constant maturity (as
compiled and published in the most recent Federal Reserve Statistical Release
H.15(519) that has become publicly available at least two business days prior to
the Change of Control Redemption Date (or, if such Statistical Release is no
longer published, any publicly available source of similar market data)) most
nearly equal to the period from the Change of Control Redemption Date to March
1, 2003; provided, however, that if the period from the Change of Control
Redemption Date to March 1, 2003 is not equal to the constant maturity of a
United States Treasury security for which a weekly average yield is given, the
Treasury Rate shall be obtained by linear interpolation (calculated to the
nearest one-twelfth of a year) from the weekly average yields of United States
Treasury Securities for which such yields are given except that if the period
from the Change of Control Redemption Date to March 1, 2003 is less than one
year, the weekly average yield on actually traded United States Treasury
Securities adjusted to a constant maturity of one year shall be used.

6.   Notice of Redemption.

              Notice of redemption will be mailed by first-class mail at least
30 days but not more than 60 days before the Redemption Date to each Holder of
Securities to be redeemed at its registered address. The Trustee may select for
redemption portions of the principal amount of Securities that have
denominations equal to or larger than $1,000 principal amount. Securities and
portions of them the Trustee so selects shall be in amounts of $1,000 principal
amount or integral multiples thereof.

              If any Security is to be redeemed in part only, the notice of
redemption that relates to such Security shall state the portion of the
principal amount thereof to be redeemed. A new Security in a principal amount
equal to the unredeemed portion thereof will be issued in the name of the Holder
thereof upon cancellation of the original Security. On and after the Redemption
Date, interest will cease to accrue on Securities or portions thereof called for
redemption so long as the Company has deposited with the Paying Agent for the
Securities funds in satisfaction of the redemption price pursuant to the
Indenture and the Paying Agent is not prohibited from paying such funds to the
Holders pursuant to the terms of the Indenture.

7.   Change of Control Offer.

              Following the occurrence of a Change of Control (the date of such
occurrence being the "Change of Control Date"), the Company shall, within 30
days after the Change of Control Date, offer to purchase all Securities then
outstanding at a purchase price in cash equal to 101% of the aggregate principal
amount thereof, plus accrued and unpaid interest thereon, if any, to the date of
such purchase (subject to the right of Holders of record on the relevant
Interest Record Date to receive interest due on the relevant Interest Payment
Date).

8.   Limitation on Disposition of Assets.

              The Company is, subject to certain conditions and certain
exceptions, obligated to offer to purchase the Securities at a purchase price
equal to 100% of the principal amount thereof, plus accrued and unpaid interest
thereon, if any, to the date of such purchase (subject to the right of Holders
of record on the relevant Interest Record Date to receive interest due on the
relevant Interest Payment Date) with the proceeds of certain asset dispositions.

<PAGE>   100

9.   Denominations; Transfer; Exchange.

              The Securities are in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000. A Holder shall
register the transfer of or exchange Securities in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay certain transfer
taxes or similar governmental charges payable in connection therewith as
permitted by the Indenture. The Registrar need not register the transfer of or
exchange any Securities or portions thereof selected for redemption, except the
unredeemed portion of any security being redeemed in part.

10.  Persons Deemed Owners.

              The registered Holder of a Security shall be treated as the owner
of it for all purposes.

11.  Unclaimed Funds.

              If funds for the payment of principal or interest remain unclaimed
for two years, the Trustee and the Paying Agent will repay the funds to the
Company at their written request. After that, all liability of the Trustee and
such Paying Agent with respect to such funds shall cease.

12.  Legal Defeasance and Covenant Defeasance.

              The Company and the Guarantors may be discharged from their
obligations under the Indenture, the Securities and the Subsidiary Guarantees,
except for certain provisions thereof, and may be discharged from obligations to
comply with certain covenants contained in the Indenture, the Securities and the
Subsidiary Guarantees, in each case upon satisfaction of certain conditions
specified in the Indenture.

13.  Amendment; Supplement; Waiver.

              Subject to certain exceptions, the Indenture and the Securities
(including the Subsidiary Guarantees) may be amended or supplemented with the
written consent of the Holders of at least a majority in aggregate principal
amount of the Securities then outstanding, and any existing Default or Event of
Default or compliance with any provision may be waived with the consent of the
Holders of a majority in aggregate principal amount of the Securities then
outstanding. Without notice to or consent of any Holder, the parties thereto may
amend or supplement the Indenture, the Securities and the Subsidiary Guarantees
to, among other things, cure any ambiguity, defect or inconsistency, provide for
uncertificated Securities in addition to or in place of certificated Securities
or comply with any requirements of the SEC in connection with the qualification
of the Indenture under the TIA, or make any other change that does not
materially adversely affect the rights of any Holder.

14.  Restrictive Covenants.

              The Indenture contains certain covenants that, among other things,
limit the ability of the Company and the Restricted Subsidiaries to make
restricted payments, to incur indebtedness, to sell assets, to permit
restrictions on dividends and other payments by Subsidiaries to the Company, to
consolidate, merge or sell all or substantially all of its assets and to engage
in transactions with affiliates. The limitations are subject to a number of
important qualifications and exceptions. The Company must report annually to the
Trustee on compliance with such limitations.

<PAGE>   101


15.  Defaults and Remedies.

              If an Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in aggregate principal amount of Securities then
outstanding may declare all the Securities to be due and payable immediately in
the manner and with the effect provided in the Indenture. Holders of Securities
may not enforce the Indenture, the Securities or the Subsidiary Guarantees
except as provided in the Indenture. The Trustee is not obligated to enforce the
Indenture, the Securities or the Subsidiary Guarantees unless it has received
indemnity satisfactory to it. The Indenture permits, subject to certain
limitations therein provided, Holders of a majority in aggregate principal
amount of the Securities then outstanding to direct the Trustee in its exercise
of any trust or power. The Trustee may withhold from Holders of Securities
notice of certain continuing Defaults or Events of Default if it determines that
withholding notice is in their interest.

16.  Trustee Dealings with Company and Guarantors.

              The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities and may otherwise deal
with the Company, the Guarantors, their respective Subsidiaries or their
respective Affiliates as if it were not the Trustee.

17.  No Recourse Against Others.

              No director, officer, employee, incorporator or stockholder of the
Company or any Guarantor, as such, shall have any liability for any obligations
of the Company or any Guarantor under the Securities or the Subsidiary
Guarantees, as the case may be, or the Indenture or for any claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder by
accepting a Security waives and releases all such liability. The waiver and
release are part of the consideration for the issuance of the Securities and the
Subsidiary Guarantees.

18.  Authentication.

              This Security shall not be valid until the Trustee or
authenticating agent signs the certificate of authentication on this Security.

19.  Abbreviations and Defined Terms.

              Customary abbreviations may be used in the name of a Holder of a
Security or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian) and U/G/M/A (= Uniform Gifts
to Minors Act).

20.  CUSIP Numbers.

              Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company has caused CUSIP numbers
to be printed on the Securities as a convenience to the Holders of the
Securities. No representation is made as to the accuracy of such numbers as
printed on the Securities and reliance may be placed only on the other
identification numbers printed hereon.

21.  Governing Law.

              The laws of the State of New York shall govern the Indenture, this
Security and any Guarantee hereof without regard to principles of conflicts of
laws to the extent that the application of the laws of another jurisdiction
would be required thereby.

                          SENIOR SUBORDINATED GUARANTEE

              Each undersigned Guarantor (as defined in the Indenture referred
to in the Security upon which this notation is endorsed) hereby unconditionally

     Re:      8 3/8% Senior Subordinated Notes due 2008
              (the "Securities") of LIN Acquisition Company

              This Certificate relates to $_______ principal amount of
Securities held in the form of* ___ a beneficial interest in a Global Security
or* _______ Physical Securities by ______ (the "Transferor").

The Transferor:*

     [ ]      has requested by written order that the Registrar deliver in
exchange for its beneficial interest in the Global Security held by the
Depositary a Physical Security or Physical Securities in definitive, registered
form of authorized denominations and an aggregate number equal to its beneficial
interest in such Global Security (or the portion thereof indicated above); or

     [ ]      has requested that the Registrar by written order exchange or
register the transfer of a Physical Security or Physical Securities.

     [ ]      In connection with such request and in respect of each such
Security, the Transferor does hereby certify that the Transferor is familiar
with the Indenture relating to the above captioned Securities and the
restrictions on transfers thereof as provided in Section 2.16 of such Indenture,
and that the transfer of the Securities does not require registration under the
Securities Act of 1933, as amended (the "Act"), because*:

     [ ]      Such Security is being acquired for the Transferor's own account,
without transfer (in satisfaction of Section 2.16 of the Indenture).

     [ ]      Such Security is being transferred to a "qualified institutional
buyer" (as defined in Rule 144A under the Act), in reliance on Rule 144A.

     [ ]      Such Security is being transferred to an institutional "accredited
investor" (within the meaning of subparagraph (a)(1), (2), (3) or (7) of Rule
501 under the Act) which delivers a certificate to the Trustee in the form of
Exhibit E to the Indenture.

     [ ]      Such Security is being transferred in reliance on Rule 144 under
the Act.

     [ ]      Such Security is being transferred in reliance on and in
compliance with an exemption from the registration requirements of the Act other
than Rule 144A or Rule 144 under the Act to a person other than an institutional
"accredited investor." [An Opinion of Counsel to the effect that such transfer
does not require registration under the Securities Act accompanies this
certification.]

                   Form of Transferee Letter of Representation


LIN ACQUISITION COMPANY
One Richmond Square, Suite 230E
Providence, Rhode Island 02906


Ladies and Gentlemen:

              This certificate is delivered to request a transfer of $________
principal amount of the 8 3/8% Senior Subordinated Notes due 2008 (the "Notes")
of LIN ACQUISITION COMPANY (the "Company"). Upon transfer, the Notes would be
registered in the name of the new beneficial owner as follows:

              Name:
                   ----------------------------------
              Address:
                       ------------------------------
              Taxpayer ID Number:
                                  -------------------

              The undersigned represents and warrants to you that:

              1.    We are an institutional "accredited investor" (as defined in
Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933 (the
"Securities Act")) purchasing for our own account or for the account of such an
institutional "accredited investor" at least $250,000 principal amount of the
Notes, and we are acquiring the Notes not with a view to, or for offer or sale
in connection with, any distribution in violation of the Securities Act. We have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risk of our investment in the Notes and we invest
in or purchase securities similar to the Notes in the normal course of our
business. We and any accounts for which we are acting are each able to bear the
economic risk of our or its investment.

              2.    We understand that the Notes have not been registered under
the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence. We agree on our own behalf and on behalf of
any investor account for which we are purchasing Notes to offer, sell or
otherwise transfer such Notes prior to the date which is two years after the
later of the date of original issue and the last date on which the Company or
any affiliate of the Company was the owner of such Notes (or any predecessor
thereto) (the "Resale Restriction Termination Date") only (a) to the Company,
(b) pursuant to a registration statement which has been declared effective under
the Securities Act, (c) in a transaction complying with the requirements of Rule
144A under the Securities Act, to a person we reasonably believe is a qualified
institutional buyer under Rule 144A (a "QIB") that purchases for its own account
or for the account of a QIB and to whom notice is given that the transfer is
being made in reliance on Rule 144A, (d) to an institutional "accredited
investor" within the meaning of Rule 501(a)(1), (2), (3) or (7) under the
Securities Act that is purchasing for its own account or for the account of such
an institutional "accredited investor," in each case in a minimum principal
amount of Notes of $250,000, (e) pursuant to offers and sales that occur outside
the United States within the meaning of Regulation S under the Securities Act or
(f) pursuant to any other available exemption from the registration requirements
of the Securities Act, subject in each of the foregoing cases to any requirement
of law that the disposition of our property or the property of such investor
account or accounts be at all times within 


                                      E-1

our or their control and in compliance with any applicable state securities
laws. The foregoing restrictions on resale will not apply subsequent to the
Resale Restriction Termination Date. If any resale or other transfer of the
Notes is proposed to be made pursuant to clause (d) above prior to the Resale
Restriction Termination Date, the transferor shall deliver a letter from the
transferee substantially in the form of this letter to the Company and the
Trustee, which shall provide, among other things, that the transferee is an
institutional "accredited investor" within the meaning of Rule 501(a)(1), (2),
(3) or (7) under the Securities Act and that it is acquiring such Notes for
investment purposes and not for distribution in violation of the Securities Act.
Each purchaser acknowledges that the Company and the Trustee reserve the right
prior to any offer, sale or other transfer prior to the Resale Restriction
Termination Date of the Notes pursuant to clause (d), (e) or (f) above to
require the delivery of an opinion of counsel, certificates and/or other
information satisfactory to the Company and the Trustee.

Dated:                                      TRANSFEREE:

Ladies and Gentlemen:

       United States;

              (2) either (a) at the time the buy offer was originated, the
       transferee was outside the United States or we and any person acting on
       our behalf reasonably believed that the transferee was outside the United
       States, or (b) the transaction was executed in, on or through the
       facilities of a designated off-shore securities market and neither we nor
       any person acting on our behalf knows that the transaction has been
       prearranged with a buyer in the United States;

              (3) no directed selling efforts have been made in the United
       States in contravention of the requirements of Rule 903(b) or Rule 904(b)
       of Regulation S, as applicable;

       applicable to the Securities.
