by the TIA by reference to another statute or defined by the SEC in a rule under
the TIA have the meanings so assigned to them therein.

        SECTION 1.04. Rules of Construction. Unless the context otherwise
requires: (1) a term has the meaning assigned to it in this Indenture; (2) an
accounting term not otherwise defined herein has the meaning assigned to it
under GAAP; (3) "OR" is not exclusive; (4) words in the singular include the

                                     ARTICLE 2

                              THE EXCHANGE DEBENTURES

        SECTION 2.01. Form and Dating. (a) The Exchange Debentures and the
certificate of authentication of the Trustee or an authenticating agent
appointed on its behalf pursuant to Section 2.02 shall be substantially in the
form of Exhibit A hereto, bearing such legend as is required pursuant to this
Section 2.01. The Exchange Debentures may have notations, legends or
endorsements required by law, stock exchange rule or usage. Each Exchange
Debenture shall be



                                       24











dated the date of its authentication. The Exchange Debentures shall be in
denominations of $10,000 principal amount and integral multiples thereof.

        The terms and provisions contained in the Exchange Debentures shall
constitute, and are hereby expressly made, a part of this Indenture and to the
extent applicable, Parent and the Trustee, by their execution and delivery of
this Indenture, expressly agree to such terms and provisions and to be bound
thereby.

        Exchange Debentures shall be issued initially in the form of one or more
Global Exchange Debentures in definitive, fully registered form, without
interest coupons, substantially in the form of Exhibit A hereto, bearing such
legend as is required pursuant to this Section 2.01 (the "GLOBAL EXCHANGE
DEBENTURES"), will be deposited on the Exchange Date with, or on behalf of, the
Depositary and registered in the name of Cede & Co., as nominee of the
Depositary (such nominee being referred to herein as the "GLOBAL EXCHANGE
DEBENTURE HOLDER"), duly executed by Parent and authenticated by the Trustee as
herein provided. The aggregate principal amount of the Global Exchange
Debentures may from time to time be increased or decreased by adjustments made
on the records of the Trustee, as custodian for the Depositary or its nominee,
as hereinafter provided.

        Any person having a beneficial interest in the Global Exchange
Debentures may, upon request to the Trustee, exchange such beneficial interest
for Exchange Debentures in definitive form (each a "CERTIFICATED EXCHANGE
DEBENTURE"). Upon any such issuance, the Trustee is required to register such
Exchange Debentures in the name of, and cause the same to be delivered to, such
persons or persons (or the nominee of any thereof). Such Exchange Debentures
will be issued in fully registered form. In addition, if (i) Parent notifies the
Trustee in writing that the Depositary is no longer willing or able to act as a
depositary and Parent is unable to locate a qualified successor within 90 days
or (ii) Parent, at its option, notifies the Trustee in writing that it elects to
cause the issuance of Certificated Exchange Debentures, then, upon surrender by
the relevant Global Exchange Debenture Holder of its Global Exchange Debentures,
Certificated Exchange Debentures in such form will be issued to each person that
such Global Exchange Debenture Holder and the Depositary identifies as being the
beneficial owner of the related Exchange Debentures.

        (b) Each Global Exchange Debenture shall bear the following legend on
the face thereof:

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF
         THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO THE
         COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT,
         AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR
         IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
         DTC (AND ANY PAYMENT



                                       25













         HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED
         BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER
         USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
         INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
         HEREIN.

         TRANSFERS OF THIS GLOBAL EXCHANGE DEBENTURE SHALL BE LIMITED TO
         TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A
         SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS
         OF THIS GLOBAL EXCHANGE DEBENTURE SHALL BE LIMITED TO TRANSFERS MADE IN
         ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN SECTIONS 2.06 AND 2.07 OF
         THE INDENTURE.

        SECTION 2.02. Execution and Authentication; Authentication Agent. Two
Officers of Parent shall sign each Exchange Debenture for Parent by manual or
facsimile signature. If an Officer whose signature is on an Exchange Debenture
no longer holds that office at the time the Exchange Debenture is authenticated,
the Exchange Debenture shall nevertheless be valid.

        An Exchange Debenture shall not be valid until authenticated by the
manual signature of the Trustee, and the Trustee's signature shall be conclusive
evidence that the Exchange Debenture has been authenticated under this
Indenture. The form of Trustee's certificate of authentication to be borne by
the Exchange Debentures shall be substantially as set forth in Exhibit A. The
Trustee may appoint an authenticating agent acceptable to Parent to authenticate
the Exchange Debentures. Unless limited by the terms of such appointment, an
authenticating agent may authenticate Exchange Debentures whenever the Trustee
may do so. Each reference in this Indenture to authentication by the Trustee
includes authentication by such agent. An authenticating agent has the same
rights as an Agent to deal with Parent or any of its Affiliates. If an
appointment of an authenticating agent is made pursuant to this Section 2.02,
the Exchange Debentures may have endorsed thereon, in lieu of the Trustee's
certificate of authentication, an alternative certificate of authentication
substantially in the form set forth in Exhibit A.

        The Trustee shall, upon receipt of a written order signed by two
Officers of Parent, authenticate Exchange Debentures for issuance on the
Exchange Date in the aggregate principal amount of up to $141,910,000
(notwithstanding anything to the contrary contained in this Indenture, the
Exchange Debentures or otherwise, the aggregate principal amount of outstanding
Exchange Debentures may not exceed that amount at any time, except as provided
in Section 2.09).

        SECTION 2.03. Registrar and Paying Agent. Parent shall maintain an
office or agency (the "REGISTRAR") where Exchange Debentures may be presented
for registration of transfer or for exchange (subject to Sections 2.06 and 2.07)
and an office or agency (the "PAYING AGENT")



                                       26











where Exchange Debentures may be presented for payment and an office or agency
where notices to or upon Parent in respect of the Exchange Debentures or this
Indenture may be served. The Registrar shall keep a register of the Exchange
Debentures and of their transfer and exchanhe. Parent may appoint one or more
co-registrars and one or more additional paying agents. The term "Paying Agent"
includes any additional paying agent. Parent may change the Paying Agent,
Registrar or co-registrar without prior notice to any Holder. Parent shall
notify the Trustee and the Trustee shall notify the Holders of the name and
address of any Agent not a party to this Indenture. Parent shall enter into an
appropriate agency agreement with any Agent not a party to this Indenture, and
such agreement shall incorporate the provisions of the TIA and implement the
provisions of this Indenture that relate to such Agent.

        Parent initially appoints the Trustee as Registrar (subject to Section
2.06), Paying Agent and agent for service of notices and demands in connection
with the Exchange Debentures. Parent or any of its Affiliates may act as Paying
Agent, Registrar or co-registrar. If Parent fails to appoint or maintain a
Registrar and/or Paying Agent, subject to Section 2.06, the Trustee shall act as
such, and shall be entitled to appropriate compensation in accordance with
Section 7.07.

        SECTION 2.04. Paying Agent to Hold Money in Trust. Parent shall require
each Paying Agent other than the Trustee to agree in writing that the Paying
Agent will hold in trust for the Holders' benefit or the Trustee all money the
Paying Agent holds for the redemption or purchase of the Exchange Debentures or
for the payment of principal of, or premium, if any, or interest on the Exchange
Debentures, and will notify the Trustee of any default by Parent in providing
the Paying Agent with sufficient funds to redeem or purchase the Exchange
Debentures or make any payment on the Exchange Debentures as and to the extent
required to be redeemed, purchased or paid under the terms of this Indenture.
While any such default continues, the Trustee may require the Paying Agent to
pay all money it holds to the Trustee and account for any funds disbursed.
Parent at any time may require the Paying Agent to pay all money it holds to the
Trustee. Upon payment over to the Trustee, the Paying Agent (if other than
Parent or any of its Affiliates) shall have no further liability for the money
it delivered to the Trustee. If Parent or any of its Subsidiaries acts as Paying
Agent, it shall segregate and hold in a separate trust fund for the Holders'
benefit all money it holds as Paying Agent.

        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 and shall otherwise comply with section 312(a) of
the TIA. If the Trustee is not the Registrar, Parent shall furnish to the
Trustee, at least 7 Business Days before each interest payment date and at such
other times as the Trustee may request in writing, a list in such form and as of
such date as the Trustee may reasonably require that sets forth the names and
addresses of, and the aggregate principal amount of Exchange Debentures held by,
each Holder, and Parent shall otherwise comply with section 312(a) of the TIA.

        SECTION 2.06. Transfer and Exchange. (a) Parent appoints the Trustee as
transfer and exchange agent for the purpose of any transfer or exchange of the
Exchange Debentures.



                                       27











        (b) Neither the Trustee nor the Registrar shall be required to issue,
register the transfer of or exchange any Exchange Debenture (i) to register the
transfer of or exchange any Exchange Debentvre selected for redemption, (ii) to
register the transfer of or exchange any Exchange Debenture for a period of 15
days before the mailing of a notice of redemption and ending on the date of such
mailing, (iii) to register the transfer or exchange of any Exchange Debenture
between a record date and the next succeeding interest payment date.

        (c) No service charge shall be made for any registration of transfer or
exchange (except as otherwise expressly permitted herein), but the Registrar or
Trustee may require a Holder to furnish appropriate endorsements and transfer
documents and payment of a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection therewith (other than any such
transfer tax or similar governmental charge payable upon exchanges pursuant to
Section 2.11, 3.06 or 9.05, which the Parent shall pay).

        (d) Prior to due presentment for registration of transfer of any
Exchange Debenture to the Trustee, the Trustee, any Agent and Parent shall deem
and treat the Person in whose name any Exchange Debenture is registered as the
absolute owner of such Exchange Debenture (whether or not such Exchange
Debenture shall be overdue and notwithstanding any notation of ownership or
other writing on such Exchange Debenture made by anyone other than Parent, the
Registrar, or any co-registrar) for the purpose of receiving payment of
principal of, premium, if any, and interest on such Exchange Debenture and for
all other purposes, and notice to the contrary shall not affect the Trustee, any
Agent or Parent.

        (e) A Holder may transfer an Exchange Debenture only by written
application to the Registrar stating the name of the proposed transferee and
otherwise complying with the terms of this Indenture. No such transfer shall be
effected until, and such transferee shall succeed to the rights of a Holder only
upon, final acceptance and registration of the transfer by the Registrar. Prior
to the registration of any transfer by a Holder as provided herein, Parent, the
Trustee, and any agent of Parent shall treat the person in whose name the
Exchange Debenture is registered as the absolute owner thereof for all purposes
whether or not the Exchange Debenture shall be overdue, and neither Parent, the
Trustee, nor any such agent shall be affected by notice to the contrary.
Furthermore, any Holder of a Global Exchange Debenture shall, by acceptance of
such Global Exchange Debenture, agree that transfers of beneficial interests in
such Global Exchange Debenture may be effected through a book entry system
maintained by the Holder of such Global Exchange Debenture (or its agent) and
that ownership of a beneficial interest in the Global Exchange Debenture shall
be required to be reflected in a book entry. When Exchange Debentures are
presented to the Registrar or a co-registrar with a request to register the
transfer or to exchange them for an equal principal amount of Exchange
Debentures of other authorized denominations, the Registrar or co-registrar, as
relevant, shall register the transfer or make the exchange as requested if the
requirements for such transactions set forth herein are met. To permit
registrations of transfers and exchanges, Parent shall execute and the Trustee
shall authenticate Exchange Debentures at the Registrar's request.



                                       28











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

        SECTION 2.07. Book-entry Provisions for Global Exchange Debentures. (a)
The Global Exchange Debentures initially shall (i) be registered in the name of
the Depositary for such Global Exchange Debentures or the nominee of such
Depositary, (ii) be delivered to the Trustee as custodian for such Depositary
and (iii) bear legends as set forth in Section 2.01.

        Members of, or participants in, the Depositary ("AGENT MEMBERS") shall
have no rights under this Indenture with respect to any Global Exchange
Debenture held on their behalf by the Depositary, or the Trustee as its
custodian, and the Depositary may be treated by Parent, the Trustee and any
agent of Parent or the Trustee as the absolute owner of such Global Exchange
Debenture for all purposes whatsoever. Notwithstanding the foregoing, nothing
herein shall prevent Parent, the Trustee or any agent of Parent or the Trustee,
from giving effect to any written certification, proxy or other authorization
furnished by the Depositary or shall impair, as between the Depositary and its
Agent Members, the operation of customary practices governing the exercise of
the rights of a Holder of any Exchange Debenture.

        (b) Transfers of a Global Exchange Debenture shall be limited to
transfers of such Global Exchange Debenture in whole, but not in part, to the
Depositary, its successors or their respective nominees. Interests of beneficial
owners in a Global Exchange Debenture may be transferred in accordance with the
rules and procedures of the Depositary. In addition, Certificated Exchange
Debentures shall be transferred to all beneficial owners in exchange for their
beneficial interests in the Global Exchange Debentures if (i) the Depositary
notifies Parent that it is unwilling or unable to continue as Depositary for the
Global Exchange Debentures and a successor depositary is not appointed by Parent
within 90 days of such notice or (ii) an Event of Default of which the Trustee
has actual notice has occurred and is continuing and the Registrar has received
a request from the Depositary to issue such Certificated Exchange Debentures.

        (c) In connection with any transfer of a portion of the beneficial
interests in the Global Exchange Debentures to beneficial owners pursuant to
paragraph (b) of this Section, the Registrar shall reflect on its books and
records the date and a decrease in the principal amount of the Global Exchange
Debentures in an amount equal to the principal amount of the beneficial interest
in the Global Exchange Debentures to be transferred, and Parent shall execute,
and the Trustee shall authenticate and deliver, one or more Certificated
Exchange Debentures of like tenor and amount.

        (d) The registered holder of a Global Exchange Debenture may grant
proxies and otherwise authorize any person, including Agent Members and persons
that may hold interests through Agent Members, to take any action which a Holder
is entitled to take under this Indenture or the Exchange Debentures.



                                       29











        SECTION 2.08. Replacement Exchange Debentures. Holders shall surrender
mutilated Exchange Debentures to the Trustee. If any mutilated Exchange
Debenture is surrendered to the Trustee, or if Parent and the Trustee receive
evidence to their satisfaction of the destruction, loss or theft of any Exchange
Debenture, Parent shall issue and the Trustee shall authenticate, a replacement
Exchange Debenture if the Trustee's requirements are met, and each such
replacement Exchange Debenture shall be an additional obligation of Parent. If
the Trustee or Parent requires, the Holder must supply an indemnity bond that is
sufficient, in the reasonable judgment of the Trustee and Parent, to protect
Parent, the Trustee, any Agent or any authenticating agent from any loss that
any of them may suffer if an Exchange Debenture is replaced. Parent and the
Trustee may charge for its reasonable expenses in replacing an Exchange
Debenture.

        SECTION 2.09. Outstanding Exchange Debentures. The Exchange Debentures
outstanding at any time are all the Exchange Debentures the Trustee has
authenticated except for those it has cancelled, those delivered to it for
cancellation, and those described in this Section 2.09 as not outstanding. If an
Exchange Debenture is replaced pursuant to Section 2.08, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that a bona
fide purchaser holds the replaced Exchange Debenture. If the entire principal
of, premium, if any, and accrued interest on any Exchange Debenture is
considered paid under Section 2.04, it ceases to be outstanding and interest on
it ceases to accrue. Subject to Section 2.10, an Exchange Debenture does not
cease to be outstanding because Parent or any Affiliate of Parent holds such
Exchange Debenture.

        SECTION 2.10. Treasury Exchange Debentures. In determining whether the
Holders of the required principal amount of Exchange Debentures have concurred
in any direction, waiver or consent, Exchange Debentures owned by Parent or any
Affiliate of Parent shall be considered as though they are not outstanding;
provided, however, that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Exchange Debentures that the Trustee knows are so owned shall be so disregarded.
Notwithstanding the foregoing, Exchange Debentures that Parent or any Affiliate
of Parent offers to purchase or acquires pursuant to an exchange offer, tender
offer or otherwise shall not be deemed to be owned by Parent or any Affiliate of
Parent until legal title to such Exchange Debentures passes to Parent or such
Affiliate, as the case may be.

        SECTION 2.11. Temporary Exchange Debentures. Until definitive Exchange
Debentures are ready for delivery, Parent may prepare and the Trustee on its
behalf shall authenticate temporary Exchange Debentures. Temporary Exchange
Debentures shall be substantially in the form of definitive Exchange Debentures
but may have variations that Parent considers appropriate for temporary Exchange
Debentures. Without unreasonable delay, Parent shall prepare and the Trustee on
its behalf, upon receipt of a written order signed by two Officers of Parent,
shall authenticate definitive Exchange Debentures in exchange for temporary
Exchange Debentures. Until such exchange, temporary Exchange Debentures shall be
entitled to the same rights, benefits and privileges as definitive Exchange
Debentures.



                                       30











        SECTION 2.12. Cancellation. Holders shall surrender Exchange Debentures
for cancellation to the Trustee. Parent at any time may deliver Exchange
Debentures to the Trustee for cancellation. The Registrar, any co-registrar, the
Paying Agent, Parent and its Subsidiaries shall forward to the Trustee any
Exchange Debentures surrendered to them for registration of transfer, exchange,
replacement, payment (including all Exchange Debentures called for redemption
and all Exchange Debentures accepted for payment pursuant to an Offer) or
cancellation, and the Trustee shall cancel all such Exchange Debentures and
shall return all cancelled Exchange Debentures to the Company. Parent may not
issue new Exchange Debentures to replace any Exchange Debentures that have been
cancelled by the Trustee or that have been delivered to the Trustee for
cancellation. If Parent or any Affiliate of Parent acquires any Exchange
Debentures (other than by redemption pursuant to Section 3.07 or an Offer
pursuant to Section 4.12 or 4.13), such acquisition shall not operate as a
redemption or satisfaction of the Indebtedness represented by such Exchange
Debentures unless and until such Exchange Debentures are delivered to the
Trustee for cancellation.

        SECTION 2.13. Defaulted Interest. If Parent defaults in a payment of
interest on the Exchange Debentures, it shall pay the defaulted interest in any
lawful manner plus, to the extent lawful, interest payable on the defaulted
interest, to Holders on a subsequent special record date, in each case at the
rate provided in the Exchange Debentures and Section 4.01. Parent shall, with
the Trustee's consent, fix or cause to be fixed each such special record date
and payment date. At least 15 days before the special record date, Parent (or,
at the request of Parent, the Trustee in the name of, and at the expense of,
Parent) shall mail a notice that states the special record date, the related
payment date and the amount of interest to be paid.

        SECTION 2.14. Record Date. The record date for purposes of determining
the identity of holders of Exchange Debentures entitled to vote or consent to
any action by vote or consent authorized or permitted under this Indenture shall
be determined as provided for in section 316(c) of the TIA.

        SECTION 2.15. CUSIP and CINS Numbers. A "CUSIP" or "CINS" number will be
printed on the Exchange Debentures and the Trustee shall use CUSIP or CINS
numbers, as the case may be, in notices of redemption, purchase or exchange as a
convenience to Holders, provided that any such notice may state that no
representation is made as to the correctness or accuracy of such numbers printed
in the notice or on the Exchange Debentures and that reliance may be placed only
on the other identification numbers printed on the Exchange Debentures. Parent
will promptly notify the Trustee of any change in the CUSIP or CINS number, as
the case may be.



                                       31










                                     ARTICLE 3

                        REDEMPTIONS AND OFFERS TO PURCHASE

        SECTION 3.01. Notices to Trustee. If Parent elects to redeem Exchange
Debentures pursuant to Section 3.07, it shall furnish to the Trustee, at least
15 but not more than 30 days before notice of any redemption is to be mailed to
Holders (or such shorter time as may be satisfactory to the Trustee), (x) an
Officers' Certificate stating (i) that Parent has elected to redeem Exchange
Debentures pursuant to Section 3.07, (ii) the date notice of redemption is to be
mailed to Holders, (iii) the redemption date, (iv) the aggregate principal
amount of Exchange Debentures to be redeemed, (v) the redemption price for such
Exchange Debentures and (vi) the amount, if any, of accrued and unpaid interest
on such Exchange Debentures as of the redemption date and (y) an Opinion of
Counsel that Parent is entitled to redeem the Exchange Debentures pursuant to
Section 3.07. If the Trustee is not the Registrar, Parent shall, concurrently
with delivery of its notice to the Trustee of a redemption, cause the Registrar
to deliver to the Trustee a certificate (upon which the Trustee may rely)
setting forth the name of, and the aggregate principal amount of the Exchange
Debentures held by, each Holder.

        If Parent is required to offer to purchase Exchange Debentures pursuant
to Section 4.12 or 4.13, it shall furnish to the Trustee, at least 2 Business
Days before notice of the Offer is to be mailed to Holders, an Officers'
Certificate setting forth (i) that the Offer is being made pursuant to Section
4.12 or 4.13, as the case may be, (ii) the Purchase Date, (iii) the maximum
principal amount of Exchange Debentures Parent is offering to purchase pursuant
to the Offer, (iv) the purchase price for such Exchange Debentures and (v) the
amount, if any, of accrued and unpaid interest on such Exchange Debentures as of
the Purchase Date.

        Parent will also provide the Trustee with any additional information
that the Trustee reasonably requests in connection with any redemption or Offer.

        SECTION 3.02. Selection of Exchange Debentures to Be Redeemed or
Purchased. If less than all outstanding Exchange Debentures are to be redeemed
or if less than all Exchange Debentures tendered pursuant to an Offer are to be
accepted for payment, the Trustee shall select the outstanding Exchange
Debentures to be redeemed or accepted for payment on a pro rata basis, by lot or
by any other method that the Trustee deems fair and appropriate. If Parent
elects to mail notice of a redemption to Holders, the Trustee shall at least 15
days prior to the date notice of redemption is to be mailed (i) select the
Exchange Debentures to be redeemed from Exchange Debentures outstanding not
previously called for redemption in the manner specified by the Trustee and (ii)
notify Parent of the names of each Holder of Exchange Debentures selected for
redemption, the principal amount of Exchange Debentures held by each such Holder
and the principal amount of such Holder's Exchange Debentures that are to be
redeemed. If less than all Exchange Debentures tendered pursuant to an Offer are
to be accepted for payment, the Trustee shall select on or prior to the Purchase
Date for such Offer the Exchange Debentures to be accepted for payment. The
Trustee shall select for redemption or purchase Exchange Debentures or portions
of Exchange Debentures in principal amounts at maturity of $10,000 or



                                       32













integral multiples thereof; except that if all of the Exchange Debentures of a
Holder are selected for redemption or purchase, the aggregate principal amount
of the Exchange Debentures held by such Holder, even if not an integral multiple
of $10,000, may be redeemed or purchased. Except as provided in the preceding
sentence, provisions of this Indenture that apply to Exchange Debentures called
for redemption or tendered pursuant to an Offer also apply to portions of
Exchange Debentures called for redemption or tendered pursuant to an Offer. The
Trustee shall notify Parent promptly of the Exchange Debentures or portions of
Exchange Debentures to be called for redemption or selected for purchase.

        SECTION 3.03. Notice of Redemption. (a) At least 30 days but not more
than 60 days before any redemption date Parent shall mail by first class mail a
notice of redemption to the Trustee. With respect to any redemption of Exchange
Debentures, the notice shall identify the Exchange Debentures or portions
thereof to be redeemed, including CUSIP or CINS numbers, and shall state: (1)
the redemption date; (2) the redemption price for the Exchange Debentures and
the amount, if any, of unpaid and accrued interest on such Exchange Debentures
as of the date of redemption and the premium, if any, on the Exchange Debentures
as of the date of redemption; (3) the section of this Indenture pursuant to
which the Exchange Debentures called for redemption are being redeemed; (4) if
any Exchange Debenture is being redeemed in part, the portion of the principal
amount of such Exchange Debenture to be redeemed and that, after the redemption
date, upon surrender of such Exchange Debenture, a new Exchange Debenture or
Exchange Debentures in principal amount equal to the unredeemed portion will be
issued; (5) the name and address of the Paying Agent; (6) that Exchange
Debentures called for redemption must be surrendered to the Paying Agent to
collect the redemption price for, and any accrued and unpaid interest on such
Exchange Debentures as of the date of redemption; (7) that, unless Parent
defaults in making such redemption payment, interest on Exchange Debentures
called for redemption ceases to accrete or accrue, as the case may be, on, and
after the redemption date; and (8) that no representation is made as to the
correctness or accuracy of the CUSIP or CINS number (as applicable) listed in
such notice and printed on the Exchange Debentures.

        (b) The Trustee shall (at Parent's expense and in Parent's name) give
the notice of any redemption to Holders; provided, however, that Parent shall
deliver to the Trustee, at least 45 days prior to the date of redemption and at
least 15 days prior to the date that notice of the redemption is to be mailed to
Holders, an Officers' Certificate that (i) requests the Trustee to give notice
of the redemption to Holders, (ii) sets forth the information to be provided to
Holders in the notice of redemption, as set forth in the preceding paragraph,
and (iii) sets forth the aggregate principal amount of Exchange Debentures to be
redeemed and the amount, if any, of accrued and unpaid interest thereon as of
the date of redemption. If the Trustee is not the Registrar, Parent shall,
concurrently with any such request, cause the Registrar to deliver to the
Trustee a certificate (upon which the Trustee may rely) setting forth the name
of, the address of, and the aggregate principal amount of Exchange Debentures
held by, each Holder; provided further that any such Officers' Certificate may
be delivered to the Trustee on a date later than permitted under this Section
3.03(b) if such later date is acceptable to the Trustee.



                                       33














        SECTION 3.04. Effect of Notice of Redemption. Once notice of redemption
is mailed, Exchange Debentures called for redemption become due and payable on
the redemption date at the price set forth in the Exchange Debenture.

        SECTION 3.05. Deposit of Redemption Price. (a) Prior to 10:00 a.m. on
any redemption date, Parent shall deposit with the Paying Agent money sufficient
to pay the redemption price of, and the amount, if any, of accrued interest and
unpaid interest on all Exchange Debentures to be redeemed in immediately
available funds as of the date of redemption. After any redemption date, the
Paying Agent shall promptly return to Parent any money that Parent deposited
with the Paying Agent in excess of the amounts necessary to pay the redemption
price of, and any accrued interest on all Exchange Debentures to be redeemed.

        (b) If Parent complies with the preceding paragraph, interest on the
Exchange Debentures to be redeemed will cease to accrete or accrue, as the case
may be, on such Exchange Debentures on the applicable redemption date, whether
or not such Exchange Debentures are presented for payment. If an Exchange
Debenture is redeemed on an interest payment date, then any accrued and unpaid
interest shall be paid to the Person in whose name such Exchange Debenture was
registered at the close of business on the related interest record date, in all
other circumstances, such interest shall be paid to the Holder of such Exchange
Debenture. If any Exchange Debenture called for redemption shall not be so paid
upon surrender for redemption because of the failure of Parent to comply with
the preceding paragraph, interest will be paid on the unpaid principal, premium,
if any, and unpaid interest which has accrued to the redemption date, from the
redemption date until such amounts are paid, at the rate of interest provided in
the Exchange Debentures and Section 4.01.

        SECTION 3.06. Exchange Debentures Redeemed in Part. Upon surrender of an
Exchange Debenture that is redeemed in part, Parent shall issue and the Trustee
shall authenticate for the Holder at Parent's expense a new Exchange Debenture
equal in principal amount to the unredeemed portion of the Exchange Debenture
surrendered.

        SECTION 3.07. Redemption Provisions. The Exchange Debentures will not be
redeemable at Parent's option prior to March 1, 2003 except as described below.
Thereafter, the Exchange Debentures will be subject to redemption at the option
of Parent, in whole or in part, upon not less than 30 nor more than 60 days'
notice, at the redemption prices (expressed as percentages of principal amount
at time of such redemption thereof) set forth below plus accrued and unpaid
interest thereon, if any, to the applicable redemption date, if redeemed during
the twelve-month period beginning on March 1 of the years indicated below:

        Year                                 Percentage
- ----------------------------------------     ----------
2003....................................     105.875%
2004....................................     103.917%
2005....................................     101.958%
2006 and thereafter.....................     100.000%



                                       34











        SECTION 3.08. Mandatory Offers. (a) Within 30 days after any Change of
Control Trigger Date or Asset Sale Trigger Date, Parent shall mail to the
Trustee (who shall mail to each Holder at Parent's expense) a notice stating:
(1) that an Offer is being made pursuant to Section 4.12 or 4.13, as the case
may be, and describing the transaction or transactions that constitute the
change of control or Asset Sale, as the case may be, and the length of time the
Offer shall remain open and the maximum aggregate principal amount of Exchange
Debentures that Parent is offering to purchase pursuant to such Offer; (2) the
purchase price for the Exchange Debentures (as set forth in Section 4.12 or
4.13, as the case may be), the amount (if any) of accrued and unpaid interest on
such Exchange Debentures as of the Purchase Date, and the Purchase Date; (3)
that any Exchange Debenture not accepted for payment will continue to accrue
interest; (4) that, unless Parent defaults in making such payment, any Exchange
Debenture accepted for payment pursuant to the Offer will cease to accrue
interest after the relevant Purchase Date; (5) that Holders may tender all or
any portion of the Exchange Debentures registered in the name of such Holder and
that any portion of an Exchange Debenture tendered must be tendered in a
principal amount of $10,000 or an integral multiple thereof; (6) that Holders
electing to tender any Exchange Debenture or portion thereof will be required to
surrender their Exchange Debenture, with the form therein entitled "Option of
Holder to Elect Purchase" completed, or transfer by book-entry transfer, to
Parent, a Depositary, if appointed by Parent, or a Paying Agent at the address
specified in the notice at least three days prior to the Purchase Date; (7) that
Holders will be entitled to withdraw their election to tender Exchange
Debentures if Parent, the Depositary or the Paying Agent, as the case may be,
receives, not later than the close of business on the last day of the relevant
Offer Period, a facsimile transmission or letter setting forth the name of the
Holder, the principal amount of Exchange Debentures delivered for purchase, and
a statement that such Holder is withdrawing his election to have such Exchange
Debentures purchased; and (8) that Holders whose Exchange Debentures are
accepted for payment in part will be issued new Exchange Debentures equal in
principal amount to the unpurchased portion of Exchange Debentures surrendered,
provided that only Exchange Debentures in a principal amount of $10,000 or
integral multiples thereof will be accepted for payment in part.

        (b) On the Purchase Date for any Offer, Parent will (i) to the extent
lawful, (x) in the case of an Offer resulting from a Change of Control, accept
for payment all Exchange Debentures or portions thereof properly tendered
pursuant to such Offer and (y) in the case of an Offer resulting from one or
more Asset Sales, accept for payment, on a pro rata basis to the extent
necessary, the Payment Amount of Exchange Debentures or portions thereof
pursuant to the Net Proceeds Offer, or if less than the Payment Amount has been
tendered, all Exchange Debentures tendered, and will deliver to the Trustee an
Officers' Certificate stating that such Exchange Debentures or portions thereof
were accepted for payment by Parent in accordance with the terms of Sections
3.08 and 4.13, (ii) deposit with the Paying Agent in immediately available funds
the aggregate purchase price of all Exchange Debentures or portions thereof
accepted for payment and any accrued and unpaid interest on such Exchange
Debentures as of the Purchase Date, and (iii) deliver, or cause to be delivered,
to the Trustee all Exchange Debentures or portions thereof so accepted together
with an Officers' Certificate setting forth the

                                       35













name of each Holder that tendered Exchange Debentures and the principal amount
of the Exchange Debentures, as the case may be, or portions thereof tendered by
each such Holder.

        (c) With respect to any Offer, (i) if less than all of the Exchange
Debentures tendered pursuant to an Offer are to be accepted for payment by
Parent for any reason, the Trustee shall select on or prior to the Purchase Date
the Exchange Debentures or portions thereof to be accepted for payment pursuant
to Section 3.02, and (ii) if Parent deposits with the Paying Agent on the
Purchase Date an amount sufficient to purchase all Exchange Debentures accepted
for payment, interest shall cease to accrue on such Exchange Debentures on the
Purchase Date; provided, however, that if Parent fails to deposit an amount
sufficient to purchase all Exchange Debentures accepted for payment, the
deposited funds shall be used to purchase on a pro rata basis all Exchange
Debentures accepted for payment and interest shall continue to accrue, as the
case may be, on all Exchange Debentures not purchased.

        (d) Promptly after consummation of an Offer, (i) the Paying Agent shall
mail to each Holder of Exchange Debentures or portions thereof accepted for
payment an amount equal to the Change of Control Purchase Price or Offered
Price, as the case may be, (ii) with respect to any tendered Exchange Debenture
not accepted for payment in whole or in part, the Trustee shall return such
Exchange Debenture to the Holder thereof, and (iii) with respect to any Exchange
Debenture accepted for payment in part, Parent shall issue and the Trustee shall
authenticate and mail to each such Holder a new Exchange Debenture equal in
principal amount to the unpurchased portion of the tendered Exchange Debenture.

        (e) Parent will (i) publicly announce the results of the Offer to
Holders on or as soon as practicable after the Purchase Date, and (ii) comply
with Rule 14e-1 under the Exchange Act and any other securities laws and
regulations to the extent such laws and regulations are applicable to any Offer.

        (f) If any of this Section 3.08, Section 4.12 or Section 4.13 conflict
with duties imposed upon Parent by virtue of any applicable United States
securities laws or regulations, Parent shall comply with such securities laws or
regulations and will not be deemed to have breached its obligations under this
Indenture.

                                     ARTICLE 4

                                     COVENANTS

        SECTION 4.01. Payment of Exchange Debentures. Subject to the provisions
of Article 10, Parent shall pay the principal of, and premium, if any, and
interest on the Exchange Debentures on the dates and in the manner provided in
the Exchange Debentures. Holders must surrender their Exchange Debentures to the
Paying Agent to collect principal payments. The Exchange Debentures will be
payable as to principal, premium, if any, and interest at the office


                                       36














or agency of Parent maintained for such purpose within the City and State of New
York or, at the option of Parent, by wire transfer of immediately available
funds or, in the case of Certificated Exchange Debentures only, by mailing a
check to the registered address of the Holder.

        So long as the Global Exchange Debenture Holder is the registered owner
of any Exchange Debentures, the Global Exchange Debenture Holder will be
considered the sole holder of outstanding Exchange Debentures represented by
such Global Exchange Debentures under this Indenture. Payments in respect of the
principal of, premium, if any, and interest, if any, on any Notes registered in
the name of a Global Exchange Debenture Holder on the applicable record date
will be payable by the Trustee to or at the direction of such Global Exchange
Debenture Holder in its capacity as the registered holder under this Indenture.
Neither Parent nor the Trustee will have any responsibility or liability for any
aspect of the records relating to or payments made on account of Exchange
Debentures by the Depositary, or for maintaining, supervising or reviewing any
records of the Depositary relating to such Exchange Debentures.

        Principal, premium or interest shall be considered paid on the date due
if, by 3 p.m. Eastern Standard Time on the Business Day immediately preceding
such date, Parent has deposited with the Paying Agent money in immediately
available funds designated for and sufficient to pay such principal, premium or
interest; provided, however, that principal, premium or interest shall not be
considered paid within the meaning of this Section 4.01 if money intended to pay
such principal, premium or interest is held by the Paying Agent for the benefit
of holders of Senior Indebtedness of Parent pursuant to the provisions of
Article 10. The Paying Agent shall return to Parent, no later than five days
following the date of payment, any money that exceeds the amount then due and
payable on the Exchange Debentures.

        SECTION 4.02. Reports. Whether or not required by the rules and
regulations of the Securities and Exchange Commission (the "COMMISSION"), so
long as any Exchange Debentures are outstanding, Parent will file with the
Commission, to the extent such filings are accepted by the Commission, and will
furnish (within 15 days after such filing) to the Trustee and the Holders of
Exchange Debentures all quarterly and annual reports and other information,
documents and reports that would be required to be filed with the Commission
pursuant to Section 13 of the Exchange Act if Parent were required to file under
such section. In addition, Parent will make such information available to
prospective purchasers of the Exchange Debentures, securities analysts and
broker-dealers who request it in writing.

        SECTION 4.03. Compliance Certificate. Parent shall deliver to the
Trustee, within 90 days after the end of each fiscal year of Parent, an
Officers' Certificate stating that (i) a review of the activities of Parent and
its Subsidiaries during the preceding fiscal year without regard to any grace
period has been made to determine whether Parent has kept, observed, performed
and fulfilled all of its obligations under this Indenture and the Exchange
Debentures, (ii) such review was supervised by the Officers of Parent signing
such certificate, and (iii) that to the best knowledge of each Officer signing
such certificate, (a) Parent has kept, observed, performed and fulfilled each
and every covenant contained in this Indenture and is not in default in the




                                       37












performance or observance of any of the terms, provisions and conditions of this
Indenture (or, if a Default or Event of Default occurred, describing all such
Defaults or Events of Default of which each such Officer may have knowledge and
what action Parent has taken or proposes to take with respect thereto), and (b)
no event has occurred and remains in existence by reason of which payments on
account of the principal of, or premium, if any, or interest on the Exchange
Debentures are prohibited or if such event has occurred, a description of the
event and what action Parent is taking or proposes to take with respect thereto.

        So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, the annual financial
statements delivered pursuant to Section 4.02 shall be accompanied by a written
statement of Parent's independent public accountants (which shall be a firm of
established national reputation) that in making the examination necessary for
certification of such financial statements nothing has come to their attention
that would lead them to believe that Parent has violated any provisions of
Sections 4.01, 4.05, 4.06, 4.07, 4.08, 4.10, 4.12, 4.13, 4.14 or Article 5 or,
if any such violation has occurred, specifying the nature and period of
existence thereof, it being understood that such accountants shall not be liable
directly or indirectly to any Person for any failure to obtain knowledge of any
such violation.

        Parent will, so long as any of the Exchange Debentures are outstanding,
deliver to the Trustee, promptly after any Officer of Parent becomes aware of
any Default or Event of Default an Officers' Certificate specifying such Default
or Event of Default and what action Parent is taking or proposes to take with
respect thereto.

        SECTION 4.04. Stay, Extension and Usury Laws. Parent 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, extension or usury law wherever enacted, now or at any time hereafter
in force, that might affect the covenants or the performance of its obligations
under this Indenture and the Exchange Debentures; and Parent (to the extent it
may lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not, by resort to any such law, hinder, delay or
impede the execution of any power granted to the Trustee pursuant to this
Indenture, but will suffer and permit the execution of every such power as
though no such law has been enacted.

        SECTION 4.05. Limitation on Restricted Payments. Parent will not, and
will not permit the Company or any Restricted Subsidiary to, directly or
indirectly, make any Restricted Payment (except as permitted below) if at the
time of such Restricted Payment:

               (i) a Default or Event of Default shall have occurred and be
          continuing or shall occur as a consequence thereof;

               (ii) the Adjusted Coverage Ratio Incurrence Condition would not
          be satisfied; or


                                       38














               (iii) the amount of such Restricted Payment, when added to the
          aggregate amount of all other Restricted Payments (except as expressly
          provided in the second following paragraph) made after the Issue Date,
          exceeds the sum of (A) 50% of the Adjusted Consolidated Net Income
          (taken as one accounting period) from the beginning of the first
          fiscal quarter commencing after the Issue Date to the end of Parent's
          most recently ended fiscal quarter for which financial statements are
          available at the time of such Restricted Payment (or, if such
          aggregate Adjusted Consolidated Net Income shall be a deficit, minus
          100% of such aggregate deficit) plus (B) the net cash proceeds from
          the issuance and sale (other than to a Subsidiary of Parent) after the
          Issue Date of (1) Eligible Junior Securities or (2) debt securities of
          Parent that have been converted into Eligible Junior Securities that
          are not held by a Subsidiary of Parent, plus (C) to the extent that
          any Restricted Investment that was made after the Issue Date is sold
          for cash or otherwise liquidated or repaid for cash, the lesser of (x)
          the cash return of capital with respect to such Restricted Investment
          (less the cost of disposition, if any) and (y) the initial amount of
          such Restricted Investment plus (D) the amount of Restricted
          Investment outstanding in an Unrestricted Subsidiary at the time such
          Unrestricted Subsidiary is designated a Restricted Subsidiary of the
          Company in accordance with the definition of "Unrestricted
          Subsidiary".

        The foregoing provisions will not prohibit (1) the payment of any
dividend by Parent, the Company or any Restricted Subsidiary within 60 days
after the date of declaration thereof, if at said date of declaration such
payment would have complied with the provisions of this Indenture; (2) the
redemption, repurchase, retirement or other acquisition of any Capital Stock of
Parent in exchange for, or out of the proceeds of, the substantially concurrent
sale (other than to a Subsidiary of Parent) of Eligible Junior Securities; (3)
the defeasance, redemption, repurchase or other retirement of Subordinated
Indebtedness in exchange for, or out of the proceeds of, the substantially
concurrent issue and sale of Eligible Junior Securities (other than such stock
(x) sold to a Subsidiary of Parent and (y) purchased with the proceeds of loans
from Parent or any of its Subsidiaries); (4) the making of a Related Business
Investment in joint ventures or Unrestricted Subsidiaries out of the proceeds of
the substantially concurrent issue and sale of Eligible Junior Securities (other
than such stock (x) sold to a Subsidiary of Parent and (y) purchased with the
proceeds of loans from Parent or any of its Subsidiaries); (5) Specified
Transaction Payments; (6) payments of up to $1.75 million to Granaria Holdings
or any of its Affiliates in the aggregate in any fiscal year pursuant to any
Related Party Agreement entered into between Granaria Holdings or any of its
Affiliates and the Company or its Subsidiaries to provide management and similar
services to any such Persons or to Parent; (7) payments by Parent to purchase,
redeem, acquire, cancel or otherwise retire for value Capital Stock of Parent,
or payments of dividends or distributions by Parent to its shareholders solely
in amounts and at the times necessary to permit such shareholders to (or permit
subsequent distributions to permit their respective shareholders to) purchase,
redeem, acquire, cancel or otherwise retire for value Capital Stock of such
shareholders, in each case held by officers, directors or employees or former
officers, directors or employees (or their transferees, estates or beneficiaries
under their estates), or a trust established for the benefit of any of the
foregoing of Parent, the Company or


                                       39













its Subsidiaries, upon death, disability, retirement, severance or termination
of employment or service or pursuant to any agreement under which such Capital
Stock or related rights were issued; provided that the amount of such payments
under this clause (7) after the Issue Date does not exceed in the aggregate $5.0
million; or (8) Restricted Investments the amount of which, together with the
amount of all other Restricted Investments made pursuant to this clause (8)
after the Issue Date, does not exceed $10.0 million, provided that, in the case
of clause (8), no Default or Event of Default shall have occurred and be
continuing or occur as a consequence of the actions or payments set forth
therein.

        Each Restricted Payment permitted pursuant to the preceding paragraph
(other than the Restricted Payments referred to in clauses (2) through (6)
thereof) shall be included once in calculating whether the conditions of clause
(iii) of the second preceding paragraph have been met with respect to any
subsequent Restricted Payments. For purposes of determining compliance with this
Section 4.05, in the event that a transaction meets the criteria of more than
one of the types of Restricted Payments described in the clauses of the
immediately preceding paragraph or of the clauses of the definition of
"Restricted Payment," Parent, in its sole discretion, shall classify such
transaction and only be required to include the amount and type of such
transaction in one of such clauses. If an issuance of Capital Stock of Parent is
applied to make a Restricted Payment pursuant to clause (2), (3) or (4) above,
then, in calculating whether the conditions of clause (iii) of the second
preceding paragraph have been met with respect to any subsequent Restricted
Payments, the proceeds of any such issuance shall be included under such clause
(iii) only to the extent such proceeds are not applied as so described in this
sentence.

        Not later than the date of making any Restricted Payment, Parent shall
cause the Company to deliver to the Trustee an Officers' Certificate stating
that such Restricted Payment is permitted and setting forth the basis upon which
the calculations required by this Section 4.05 were computed, which calculations
shall be based upon Parent's latest available financial statements.

        SECTION 4.06. Limitations on Additional Indebtedness. Parent will not
permit the Company or any Restricted Subsidiary, directly or indirectly, to
incur any Indebtedness (including without limitation Acquired Indebtedness);
provided that (i) the Company and its Restricted Subsidiaries may incur
Permitted Indebtedness and (ii) the Company may incur additional Indebtedness
if, after giving effect thereto, the Company's Consolidated Interest Coverage
Ratio on the date thereof would be at least 2.0 to 1, determined on a pro forma
basis as if the incurrence of such additional Indebtedness, and the application
of the net proceeds therefrom, had occurred at the beginning of the four-quarter
period used to calculate the Company's Consolidated Interest Coverage Ratio.

        SECTION 4.07. Limitation on the Issuance of Capital Stock of Restricted
Subsidiaries. Parent will not permit the Company or any Restricted Subsidiary,
directly or indirectly, to issue or sell any shares of its Capital Stock
(including options, warrants or other rights to purchase shares of such Capital
Stock) except (i) to Parent, the Company or a Wholly-Owned Restricted


                                       40













Subsidiary, (ii) if, immediately after giving effect to such issuance or sale,
such Restricted Subsidiary would no longer constitute a Restricted Subsidiary or
(iii) to the extent such shares represent directors' qualifying shares or shares
required by applicable law to be held by a Person other than the Company or a
Wholly-Owned Restricted Subsidiary. The proceeds of any sale of Capital Stock
permitted hereunder and referred to in clauses (ii) and (iii) above will be
treated as Net Available Proceeds and must be applied in a manner consistent
with the provisions of the covenant described in Section 4.13.

        SECTION 4.08. Limitation on Transactions with Affiliates. Parent will
not permit the Company or any Restricted Subsidiary to, directly or indirectly,
in one transaction or a series of related transactions, sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from or enter into any contract, agreement, understanding,
loan, advance or guarantee with, or for the benefit of, any Affiliate (each of
the foregoing, an "AFFILIATE TRANSACTION"), unless (i) such Affiliate
Transaction is on terms that are no less favorable to the Company or the
relevant Restricted Subsidiary than those that would have been obtained in a
comparable transaction by the Company or such Restricted Subsidiary with an
unrelated Person and (ii) the Company delivers to the Trustee (a) with respect
to any Affiliate Transaction (or series of related transactions) involving
aggregate payments in excess of $1.0 million, an Officers' Certificate
certifying that such Affiliate Transaction complies with clause (i) above and a
Secretary's Certificate which sets forth and authenticates a resolution that has
been adopted by a vote of a majority of the Independent Directors approving such
Affiliate Transaction or, if at the time fewer than three Independent Directors
are then in office, a Secretary's Certificate which sets forth and authenticates
a resolution that has been adopted unanimously by the Company's Board of
Directors and (b) with respect to any Affiliate Transaction (or series of
related transactions) involving aggregate payments of $5.0 million or more, the
certificates described in the preceding clause (a) and an opinion as to the
fairness to the Company or such Subsidiary from a financial point of view issued
by an Independent Financial Advisor; provided, however, that the following shall
not be deemed to be Affiliate Transactions: (i) transactions exclusively between
or among (1) the Company and one or more Restricted Subsidiaries or (2)
Restricted Subsidiaries, provided, in each case, that no Affiliate of the
Company (other than another Restricted Subsidiary) owns Capital Stock of any
such Restricted Subsidiary; (ii) transactions between Parent, the Company or any
Restricted Subsidiary and any qualified employee stock ownership plan
established for the benefit of the Company's or its Restricted Subsidiaries'
employees, or the establishment or maintenance of any such plan; (iii)
reasonable director, officer and employee compensation and other benefit, and

other banking, financing or underwriting activity entered into in the ordinary

(x) Specified Transaction Payments.

        SECTION 4.09. Taxes. Parent shall, and shall cause each of its
Subsidiaries to, pay prior to delinquency all taxes, assessments and
governmental levies the failure of which to pay could reasonably be expected to
result in a material adverse effect on the condition (financial or otherwise),
business or results of operations of Parent and its Subsidiaries taken as a
whole, except for those taxes contested in good faith by appropriate
proceedings.

        SECTION 4.10. Limitations on Restrictions on Distributions from
Restricted Subsidiaries. Parent will not permit the Company or any Restricted
Subsidiary to create or otherwise cause or suffer to exist or become effective
any consensual Payment Restriction with respect to any of its Restricted
Subsidiaries, except for (a) any such Payment Restriction in effect on the Issue
Date under the New Credit Agreement or the Notes Indenture or any similar
Payment Restriction under any similar credit facility, or any amendment,
restatement, renewal, replacement or refinancing of any of the foregoing,
provided that such similar Payment Restrictions are not, taken as a whole,

restated, renewed, replaced or refinanced, (c) any such Payment Restriction
under any agreement evidencing any Acquired Indebtedness that was permitted to
be incurred pursuant to this Indenture in effect at the time of such incurrence
and not created in contemplation of such event, provided that such Payment
Restriction is not extended to apply to any of the assets of the entities not
previously subject thereto, (d) any such Payment Restriction arising in
connection with Refinancing Indebtedness; provided that any such Payment
Restrictions that arise under such Refinancing Indebtedness are not, taken as a
whole, materially more restrictive than those under the agreement creating or
evidencing the Indebtedness being refunded or refinanced and (e) any such
restriction by reason of customary provisions restricting assignments,
subletting or other transfers contained in leases, licenses and similar
agreements entered into in the ordinary course of business.

        SECTION 4.11. Maintenance of Office or Agencies. Parent will maintain an
office or an agency (which may be an office of any Agent) where Exchange
Debentures may be surrendered


                                       42













for registration of transfer or exchange or for presentation for payment and
where notices and demands to or upon Parent in respect of the Exchange
Debentures and this Indenture may be served. Parent will give prompt written
notice to the Trustee of any change in the location of such office or agency. If
at any time Parent shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office, subject to Section 2.06.

        Parent may also from time to time designate one or more other offices or
agencies where the Exchange Debentures may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations. Parent
will give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or agency.

        Parent hereby designates the Corporate Trust Office of the Trustee as
one such office or agency of Parent in accordance with Section 2.03.

        SECTION 4.12. Change of Control. (a) Upon the occurrence of a Change of
Control (the "CHANGE OF CONTROL TRIGGER DATE"), each Holder of Exchange
Debentures may require Parent to repurchase all or any part (equal to $10,000 or
an integral multiple thereof) of such Holder's Exchange Debentures pursuant to
the offer described below at an offer price in cash equal to 101% of the
principal amount of the Exchange Debentures plus accrued and unpaid interest, if
any, to the date of repurchase (the "CHANGE OF CONTROL PURCHASE PRICE").

        (b) Within 30 days following any Change of Control, Parent will mail to
the Trustee (who shall mail to each Holder at Parent's expense) a notice (i)
describing the transaction or transactions that constitute the Change of
Control, (ii) offering to repurchase, pursuant to the procedures required by
Section 3.08 of this Indenture and described in such notice (a "CHANGE OF
CONTROL OFFER"), on a date specified in such notice (which shall be a business
day not earlier than 30 days or later than 60 days from the date such notice is
mailed) and for the Change of Control Purchase Price, all Exchange Debentures
properly tendered by such Holder pursuant to such offer to purchase for the
Change of Control Purchase Price and (iii) describing the procedures that
Holders must follow to accept the Change of Control Offer.

        (c) The Change of Control Offer will remain open for a period of at
least 20 Business Days following its commencement (the "CHANGE OF CONTROL OFFER
PERIOD"). No later than five Business Days after the termination of the Change
of Control Offer Period (the "CHANGE OF CONTROL PURCHASE DATE"), Parent will
purchase all Exchange Debentures tendered in response to the Change of Control
Offer. Payment for any Exchange Debentures so purchased will be made in the same
manner as interest payments are made.

        (d) Parent's obligation to make a Change of Control Offer will be
satisfied if a third party makes the Change of Control Offer in the manner and
at the times and otherwise in compliance with the requirements applicable to a
Change of Control Offer made by Parent and


                                       43













purchases all Exchange Debentures properly tendered and not withdrawn under such
Change of Control Offer.

        (e) Parent will comply with the applicable tender offer rules, including
the requirements of Rule 14e-1 under the Exchange Act and any other applicable
laws and regulations in connection with the purchase of Exchange Debentures
pursuant to a Change of Control Offer.

        SECTION 4.13. Limitations on Asset Sales. (a) Parent will not permit the
Company or any Restricted Subsidiary to consummate any Asset Sale unless (i) the
Company or such Restricted Subsidiary receives consideration at the time of such
Asset Sale at least equal to the Fair Market Value of the assets included in
such Asset Sale (evidenced by the delivery by the Company to the Trustee of an
Officers' Certificate certifying that such Asset Sale complies with this clause
(i)), (ii) immediately before and immediately giving effect to such Asset Sale,
no Default or Event of Default shall have occurred and be continuing, and (iii)
at least 80% of the consideration received by the Company or such Restricted
Subsidiary therefor is in the form of cash paid at the closing thereof. The
amount (without duplication) of any (x) Indebtedness (other than indebtedness
that is subordinated in right of payment to the Notes) of the Company or such
Restricted Subsidiary that is expressly assumed by the transferee in such Asset
Sale and with respect to which the Company or such Restricted Subsidiary, as the
case may be, is unconditionally released by the holder of such Indebtedness, and
(y) any Cash Equivalents, or other notes, securities or items of property
received from such transferee that are promptly (but in any event within 15
days) converted by the Company or such Restricted Subsidiary to cash (to the
extent of the cash actually so received), shall be deemed to be cash for
purposes of clause (ii) and, in the case of clause (x) above, shall also be
deemed to constitute a repayment of, and a permanent reduction in, the amount of
such Indebtedness for purposes of the following paragraph (b). If at any time
any non-cash consideration received by the Company or any Restricted Subsidiary
of the Company, as the case may be, in connection with any Asset Sale is
converted into or sold or otherwise disposed of for cash (other than interest
received with respect to any such non-cash consideration), then the date of such
conversion or disposition shall be deemed to constitute the date of an Asset
Sale hereunder and the Net Available Proceeds thereof shall be applied in
accordance with this Section 4.13. A transfer of assets by the Company to a
Restricted Subsidiary or by a Restricted Subsidiary to the Company or to a
Restricted Subsidiary will not be deemed to be an Asset Sale and a transfer of
assets that constitutes a Restricted Investment and that is permitted under
Section 4.05 will not be deemed to be an Asset Sale.

        (b) If the Company or any Restricted Subsidiary engages in an Asset
Sale, Parent will cause the Company or such Restricted Subsidiary, no later than
360 days after such Asset Sale, (or such longer period of time as may be
required to consummate any offer to repurchase any Indebtedness referred to in
clause (i) below in accordance with the terms thereof, if such offer to
repurchase is commenced not later than 30 days after the end of such 360 day
period), to (i) apply all or any of the Net Available Proceeds therefrom to
repay amounts outstanding under Indebtedness of the Company and its Restricted
Subsidiaries; provided, in each case, that the





                                       44












related loan commitment (if any) of any Indebtedness constituting revolving
credit debt is thereby permanently reduced by the amount of such Indebtedness so
repaid and/or (ii) invest all or any part of the Net Available Proceeds thereof
in the purchase of fixed assets to be used by the Company and its Restricted
Subsidiaries in a Related Business (together with any short-term assets
incidental thereto), or the making of a Related Business Investment. The amount
of such Net Available Proceeds not applied or invested as provided in this
paragraph will constitute "EXCESS PROCEEDS."

        (c) When the aggregate amount of Excess Proceeds equals or exceed $5.0
million (such date, the "ASSET SALE TRIGGER DATE"), Parent shall make an offer
to purchase, from all Holders of the Exchange Debentures, an aggregate principal
amount of Exchange Debentures equal to the amount of such Excess Proceeds as
follows:

               (i) Parent shall make an offer to purchase (a "NET PROCEEDS
          OFFER") from all Holders of the Exchange Debentures, in accordance
          with the procedures set forth in Section 3.08, the maximum principal
          amount (expressed as a multiple of $10,000) of Exchange Debentures
          that may be purchased out of the amount (the "PAYMENT AMOUNT") of such
          Excess Proceeds.

               (ii) The offer price for the Exchange Debentures will be payable
          in cash in an amount equal to 100% of the principal amount of the
          Exchange Debentures tendered for purchase pursuant to a Net Proceeds
          Offer, plus accrued and unpaid interest, to the date such Net Proceeds
          Offer is consummated (the "OFFERED PRICE"), in accordance with the
          procedures set forth in this Indenture. To the extent that the
          aggregate Offered Price of Exchange Debentures tendered for purchase
          pursuant to a Net Proceeds Offer is less than the Payment Amount
          relating thereto (such shortfall constituting a "NET PROCEEDS
          DEFICIENCY"), Parent may use such Net Proceeds Deficiency, or a
          portion thereof, for general corporate purposes, subject to the
          limitations of Section 4.05.

               (iii) If the aggregate Offered Price of Exchange Debentures
          validly tendered for purchase and not withdrawn by Holders thereof
          exceeds the Payment Amount, Exchange Debentures to be purchased will
          be selected on a pro rata basis. The Net Proceeds Offer shall remain
          open for a period of at least 20 Business Days following its
          commencement (the "NET PROCEEDS OFFER PERIOD"). No later than five
          Business Days after the termination of the Offer Period (the "NET
          PROCEEDS PURCHASE DATE"), Parent will purchase the principal amount of
          Exchange Debentures required to be purchased pursuant to this
          covenant. Payment for any Exchange Debentures so purchased will be
          made in the same manner as interest payments are made.

               (iv) Upon completion of such Net Proceeds Offer in accordance
          with the foregoing provisions, the amount of Excess Proceeds with
          respect to which such Net Proceeds Offer was made shall be deemed to
          be zero.


                                       45












         Parent will not enter into or suffer to exist any agreement that would
place any restriction of any kind (other than pursuant to law or regulation, the
New Credit Agreement or the Notes Indenture) on its ability to make a Net
Proceeds Offer following any Asset Sale. Parent will comply with Rule 14e-1
under the Exchange Act and any other securities laws and regulations thereunder,
if applicable, in the event that an Asset Sale occurs and Parent is required to
purchase the Exchange Debentures as described above.

        SECTION 4.14. Limitations on Activities by Parent. Parent shall not,
directly or indirectly, (i) enter into or permit to exist any transaction or
agreement (including without limitation any transaction or agreement with
respect to any incurrence or assumption of Indebtedness, any purchase, sale,
lease or exchange of any property or the rendering of any service or payment of
any funds) between itself and any other Person (including any Affiliate), other
than Permitted Parent Transactions, (ii) issue any Capital Stock other than the
Senior Preferred Stock or any any Eligible Junior Securities, or incur or assume
any Indebtedness other than pursuant to Permitted Parent Transactions, (iii)
engage in any business or conduct any activity (including the making of any
Investment or payment) or transfer any of its assets, other than the ownership
of the capital stock of the Company and the performance of Permitted Parent
Transactions in accordance with the terms thereof or (iv) consolidate or merge
with or into any other Person. Parent shall preserve, renew and keep in full
force and effect its corporate existence and any rights, privileges and
franchises necessary or desirable in the conduct of its business, and shall
comply in all material respects with all material applicable laws, ordinances,
rules, regulations, and requirements of governmental authorities, provided that
Parent may terminate any such right, privilege or franchise (other than its
corporate existence) if its Board of Directors in good faith determines that
such termination is in the best interests of Parent and not materially
disadvantageous to the Holders of the Exchange Debentures. The foregoing shall
in no event limit or restrict the ability of Parent to receive payments
(including dividends and distributions) from the Company and its Subsidiaries.

                                     ARTICLE 5

                                    SUCCESSORS

        SECTION 5.01. Limitations on Mergers and Certain Other Transactions.
Parent will not permit the Company, in a single transaction or a series of
related transactions, to (i) consolidate or merge with or into (other than a
merger with a Wholly-Owned Restricted Subsidiary solely for the purpose of
changing the Company's jurisdiction of incorporation to another State of the
United States), or sell, lease, transfer, convey or otherwise dispose of or
assign all or substantially all of the assets of the Company or the Company and
its Subsidiaries (taken as a whole), or assign any of its obligations under the
Notes and the Notes Indenture, to any Person or (ii) adopt a Plan of Liquidation
unless, in either case: (w) the Person formed by or surviving such consolidation
or merger (if other than the Company) or to which such sale, lease, conveyance
or other disposition or assignment shall be made (or, in the case of a Plan of
Liquidation, any

                                       46













Person to which assets are transferred) (collectively, the "SUCCESSOR"), is a
corporation organized and existing under the laws of any State of the United
States of America or the District of Columbia, and the Successor assumes by
supplemental indenture in a form satisfactory to the Trustee all of the
Obligations of the Company under the Notes and the Notes Indenture; (x)
immediately prior to and immediately after giving effect to such transaction and
the assumption of the obligations as set forth in clause (w) above and the
incurrence of any Indebtedness to be incurred in connection therewith, no
Default or Event of Default shall have occurred and be continuing; and (y)
immediately after and giving effect to such transaction and the assumption of
the obligations set forth in clause (w) above and the incurrence of any
Indebtedness to be incurred in connection therewith, and the use of any net
proceeds therefrom on a pro forma basis, (1) the Consolidated Net Worth of
Parent would be at least equal to the Consolidated Net Worth of Parent
immediately prior to such transaction and (2) the Company or the Successor, as
the case may be, could meet the Coverage Ratio Incurrence Condition. For
purposes of this Section 5.01, any Indebtedness of the Successor which was not
Indebtedness of the Company immediately prior to the transaction shall be deemed
to have been incurred in connection with such transaction.

                                     ARTICLE 6

                               DEFAULTS AND REMEDIES

        SECTION 6.01. Events of Default. (a) Each of the following constitutes
an event of default (an "EVENT OF DEFAULT"):

               (i) failure by Parent to pay interest on any of the Exchange
          Debentures when it becomes due and payable and the continuance of any
          such failure for 30 days;

               (ii) failure by Parent to pay the principal or premium, if any,
          on any of the Exchange Debentures when it becomes due and payable,
          whether at stated maturity, upon redemption, upon acceleration or
          otherwise;

               (iii) failure by Parent to comply with any of its agreements or
          covenants described above under Article 5, or in respect of its
          obligations to make a Change of Control Offer or a Net Proceeds Offer
          described in Sections 4.12 and 4.13, respectively;

               (iv) failure by Parent to comply with any other covenant in this
          Indenture and continuance of such failure for 60 days after notice of
          such failure has been given to Parent by the Trustee or by the Holders
          of at least 25% of the aggregate principal amount of the Exchange
          Debentures then outstanding;



                                       47













               (v) failure by any of Parent, the Company or any of its
          Restricted Subsidiaries to make any payment when due at final maturity
          after the expiration of any applicable grace period, in respect of any
          Indebtedness of Parent, the Company or any of such Restricted
          Subsidiaries, or the acceleration of the maturity of such Indebtedness
          by the holders thereof because of a default, with an aggregate
          outstanding principal amount for all such Indebtedness under this
          clause (v) of $10.0 million or more (but excluding in any event any
          such Indebtedness that is paid when so due after expiration of any
          applicable grace period, or upon acceleration of the maturity thereof,
          pursuant to any letter of credit);

               (vi) one or more final, non-appealable judgments or orders that
          exceed $10.0 million in the aggregate for the payment of money have
          been entered by a court or courts of competent jurisdiction against
          Parent or any Subsidiary of Parent and such judgment or judgments have
          not been satisfied, stayed, annulled or rescinded within 60 days of
          being entered;

               (vii) if under any Bankruptcy Law, (A) Parent, the Company or any
          Significant Subsidiary commences a voluntary case, consents to the
          entry of an order for relief against it in an involuntary case,
          consents to the appointment of a Custodian of it or for all or
          substantially all of its property, or makes a general assignment for
          the benefit of its creditors, or (B) a court of competent jurisdiction
          enters an order or decree, and such order or decree remains unstated
          and in effect for 60 days, that is for relief against Parent, the
          Company or any Significant Subsidiary in an involuntary case, appoints
          a Custodian of Parent, the Company or any Significant Subsidiary or
          for all or substantially all of the property of Parent, the Company or
          any Significant Subsidiary, or orders the liquidation of Parent, the
          Company or any Significant Subsidiary.

        (b) Any notice of default delivered to Parent by the Trustee or by
Holders of Exchange Debentures with a copy to the Trustee must specify the
Default, demand that it be remedied and state that the notice is a "NOTICE OF
DEFAULT".

        SECTION 6.02. Acceleration. (a) If an Event of Default (other than an
Event of Default under Section 6.01(a)(vii) with respect to Parent) occurs and
is continuing under this Indenture, the Trustee, by written notice to Parent, or
the Holders of at least 25% in aggregate principal amount of the Exchange
Debentures then outstanding by written notice to Parent and the Trustee may
declare all amounts owing under the Exchange Debentures to be due and payable
immediately. Upon such declaration of acceleration, the aggregate principal of,
premium, if any, and interest on the outstanding Exchange Debentures shall
immediately become due and payable.

        (b) Notwithstanding anything to the contrary in this Indenture, if an
Event of Default arises under Section 6.01(a)(vii) with respect to Parent, the
principal amount of and premium on, if any, and any accrued and unpaid interest
on all outstanding Exchange Debentures shall ipso

                                       48













facto become and be immediately due and payable without any declaration or other
act on the part of the Trustee or any Holders.

        (c) The Holders of a majority in aggregate principal amount of the then
outstanding Exchange Debentures by notice to the Trustee may rescind any
declaration of acceleration of such Exchange Debentures and its consequences if
the rescission would not conflict with any judgment or decree and if all
existing Defaults and Events of Default (other than the nonpayment of principal
of, or premium, if any, or interest on, the Exchange Debentures which shall have
become due by such declaration) shall have been cured or waived.

        SECTION 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of, or premium, if any, or interest on, the Exchange Debentures or
to enforce the performance of any provision of the Exchange Debentures or this
Indenture. The Trustee may maintain a proceeding even if it does not possess any
of the Exchange Debentures 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
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

        SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in
aggregate principal amount of the then outstanding Exchange Debentures by notice
to the Trustee may on behalf of all Holders waive any existing Default or Event
of Default and its consequences under this Indenture, except a continuing
Default or Event of Default in the payment of the principal of, premium, if any,
or interest on, any Exchange Debenture (which may only be waived with the
consent of each Holder affected). Upon any such waiver, such Default shall cease
to exist, and any Event of Default arising therefrom shall be deemed to have
been cured for every purpose of this Indenture; provided that 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 of Holders. Subject to Section
7.01(e), the Holders of a majority in aggregate principal amount of the then
outstanding Exchange Debentures 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 by this Indenture. 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 other Holders,
or would involve the Trustee in personal liability. The Trustee may take any
other action deemed proper by the Trustee that is not inconsistent with such
direction.

        SECTION 6.06. Limitations on Suits by Holders. A Holder may pursue a
remedy with respect to this Indenture or the Exchange Debentures only if: (1)
the Holder gives to the Trustee written notice of a continuing Event of Default;
(2) the Holders of at least 25% in principal amount of the then outstanding
Exchange Debentures make a written request to the Trustee to


                                       49













pursue the remedy; (3) such Holder or Holders offer to the Trustee indemnity
satisfactory to the Trustee against any loss, liability or expense; (4) the
Trustee does not comply with the request within 60 days after receipt of the
request and the offer of indemnity; and (5) during such 60-day period the
Holders of a majority in aggregate principal amount of the then outstanding
Exchange Debentures do not give the Trustee a direction 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 another Holder. Holders of the
Exchange Debentures may not enforce this Indenture or the Exchange Debentures,
except as provided herein.

        SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding any
other provision of this Indenture, but subject to Article 10, the right of any
Holder to receive payment of principal of, and premium, if any, and interest on,
an Exchange Debenture, on or after a respective due date expressed in the
Exchange Debenture, or to bring suit for the enforcement of any such payment on
or after such respective date, shall not be impaired or affected without the
consent of the Holder.

        SECTION 6.08. Collection Suit by Trustee. If an Event of Default
specified in Section 6.01(a)(i) or (a)(ii) occurs and is continuing, the Trustee
is authorized to recover judgment in its own name and as trustee of an express
trust against Parent for (i) principal, premium, if any, interest, if any,
remaining unpaid on the Exchange Debentures, (ii) interest on overdue principal
and premium, if any, and, to the extent lawful, interest, and (iii) 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 ("TRUSTEE EXPENSES").

        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 to have the claims of the Trustee (including any claim for Trustee
Expenses and for amounts due under Section 7.07) and the Holders allowed in any
Insolvency or Liquidation Proceeding or other judicial proceeding relative to
Parent, its creditors or its property and shall be entitled and empowered to
collect, receive and distribute to Holders any money or other property payable
or deliverable on any such claims and each Holder authorizes any Custodian in
any such Insolvency or Liquidation Proceeding or other judicial proceeding to
make such payments to the Trustee, and if the Trustee shall consent to the
making of such payments directly to the Holders any such Custodian is hereby
authorized to make such payments directly to the Holders, and to pay to the
Trustee any amount due to it hereunder for Trustee Expenses, and any other
amounts due the Trustee or any predecessor Trustee under Section 7.07; provided,
however, that the Trustee shall not be authorized to (i) consent to, accept or
adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Exchange Debentures or the rights of any
Holder or (ii) vote in respect of the claim of any Holder in any such Insolvency
or Liquidation Proceeding or other judicial proceeding. To the extent that the
payment of any such Trustee Expenses, and any other amounts due the Trustee
under Section 7.07 out of the estate in any such proceeding, shall be denied for
any reason, payment of the same shall be secured by a Lien on,

                                       50













and shall be paid out of, any and all distributions, dividends, money, Exchange
Debentures and other properties which the Holders may be entitled to receive in
such proceeding, whether in liquidation or under any plan of reorganization or
arrangement or otherwise.

        SECTION 6.10. Priorities. If the Trustee collects any money pursuant to
this Article 6, it shall pay out the money in the following order:

        First:         to the Trustee for all Trustee Expenses and for all
                       amounts due under Section 7.07;

        Second:        to the holders of Senior Indebtedness to the extent
                       required by Article 10;

        Third:         to Holders for amounts due and unpaid on the Exchange
                       Debentures for principal, premium, if any, interest,
                       ratably, without preference or priority of any kind,
                       according to the amounts due and payable on the Exchange
                       Debentures for principal, premium, if any, and interest,
                       if any, respectively; and

        Fourth:        to Parent or to such party as a court of competent
                       jurisdiction shall direct.

        The Trustee may fix a record date and payment date for any payment to
Holders.

        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 a 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, 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 does not apply to a suit by the
Trustee, a suit by a Holder pursuant to Section 6.06, or a suit by Holders of
more than 10% in principal amount of the then outstanding Exchange Debentures.

        SECTION 6.12. Willful Default. In the case of an Event of Default
occurring by reason of any willful action (or inaction) taken (or not taken) by
or on behalf of Parent with the intention of avoiding payment of the premium
that Parent would have had to pay if Parent then had elected to redeem the
Exchange Debentures under the provisions of Article 3 and under the Exchange
Debentures, an equivalent premium shall also become and be immediately due and
payable, to the extent permitted by law, upon the acceleration of the Exchange
Debentures.

                                      TRUSTEE

        SECTION 7.01. Duties of Trustee. (a) If an Event of Default occurs (and
has not been cured) the Trustee shall (i) exercise the rights and powers vested
in it by this Indenture, and (ii) use the same degree of care and skill in
exercising such rights and powers as a prudent man would exercise or use under
the circumstances in the conduct of his own affairs.

        (b) Except during the continuance of an Event of Default: (i) the
Trustee's duties shall be determined solely by the express provisions of this
Indenture and the Trustee need perform only those duties that are specifically
set forth in this Indenture and no others, and no implied covenants or
obligations shall be read into this Indenture against the Trustee; and (ii) 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 furnished to the Trustee and conforming
to the requirements of this Indenture. However, the Trustee shall examine the
certificates and opinions to determine whether they conform to this Indenture's
requirements.

        (c) The Trustee shall not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own wilful
misconduct, except that: (i) this Section 7.01(c) does not limit the effect of
Section 7.01(b); (ii) 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 (iii) 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 it receives pursuant to Section 6.05.

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

        (e) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or incur any liability. The Trustee shall be under no
obligation to exercise any of its rights and powers or to perform any duty under
this Indenture at the request of any Holders unless such Holders shall have
offered to the Trustee security and indemnity satisfactory to it against any
loss, liability or expense.

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


                                       52












        SECTION 7.02. Rights of Trustee. (a) The Trustee may rely on any
document it believes 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 any
such document.

        (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel, or both. The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel. The Trustee may consult with
counsel and advice of such counsel or any Opinion of Counsel shall be full and
complete authorization and protection in respect of any action taken, suffered
or omitted by it under this Indenture in good faith and in reliance on such
advice or opinion.

        (c) The Trustee may act through agents and shall not be responsible for
the misconduct or negligence of any agent appointed with due care.

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

        (e) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from Parent shall be sufficient if signed
by an Officer of Parent.

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

        SECTION 7.03. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Exchange
Debentures and may otherwise deal with Parent or any of its Affiliates with the
same rights it would have if it were not Trustee. The Trustee shall at all times
comply with Section 310(b) of the TIA as in effect from time to time. Each Agent
shall have the same rights as the Trustee under this Section 7.03.

        SECTION 7.04. 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 Exchange Debentures and it shall not be responsible for any statement or
recital in this Indenture or any statement in the Exchange Debentures or any
other document executed in connection with the issuance of the Exchange
Debentures or pursuant to this Indenture other than its certificate of
authentication.

        SECTION 7.05. Notice to Holders of Defaults and Events of Default. If a
Default or Event of Default occurs and is continuing and if it is known to the
Trustee, the Trustee shall mail to the Holders a notice of the Default or Event
of Default within 30 days after the occurrence thereof. Except in the case of a
Default or Event of Default in payment of principal or interest on any Exchange
Debenture (including any failure to redeem Exchange Debentures called for


                                       53












redemption or any failure to purchase Exchange Debentures that are tendered
pursuant to an Offer and that are required to be purchased by the terms of this
Indenture), the Trustee may withhold the notice if and so long as a committee of
its Trust Officers determines in good faith that withholding such notice is in
the Holders' interests.

        SECTION 7.06. Reports by Trustee to Holders. Within 60 days after each
May 15 after the Exchange Date the Trustee shall mail to the Holders a brief
report dated as of such reporting date that complies with section 313(a) of the
TIA (but if no event described in section 313(a) of the TIA has occurred within
the twelve months preceding the reporting date, no report need be transmitted).
The Trustee also shall comply with section 313(b)(2) of the TIA. The Trustee
shall also transmit by mail all reports as required by section 313(c) of the
TIA.

        Commencing at the time this Indenture is qualified under the TIA, a copy
of each report at the time of its mailing to Holders shall be filed with the SEC
and each stock exchange on which the Exchange Debentures are listed. Parent
shall notify the Trustee when the Exchange Debentures are listed on any stock
exchange.

        SECTION 7.07. Compensation and Indemnity. Parent shall pay to the
Trustee from time to time such compensation for its services hereunder as the
parties shall agree from time to time. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. Parent
shall reimburse the Trustee upon request for all reasonable disbursements,
advances and expenses it incurs or makes in addition to the compensation for its
services. Such expenses shall include the reasonable compensation, disbursements
and expenses of the Trustee's agents and counsel.

        Parent shall indemnify the Trustee for, from and against any and all
losses, liabilities or expenses the Trustee Incurs arising out of or in
connection with the acceptance or administration of its duties under this
Indenture (including any expenses Incurred in connection with the performance of
its duties under Section 6.08), except as set forth below. The Trustee shall
notify Parent promptly of any claim for which it may seek indemnity; provided,
however, that failure by the Trustee to provide Parent with any such notice
shall not relieve Parent of any of its obligations under this Section 7.07
except to the extent that Parent has been prejudiced by such failure. Parent
shall defend the claim and the Trustee shall cooperate in the defense of any
such claim. If, in the opinion of the Trustee's counsel, the Trustee has an
interest adverse to Parent or a potential conflict of interest exists between
the Trustee and Parent, the Trustee may have separate counsel and Parent shall
pay the reasonable fees and expenses of such counsel. Parent need not pay for
any settlement made without its consent, which consent shall not be unreasonably
withheld.

        Parent's obligations under this Section 7.07 shall survive the
satisfaction and discharge of this Indenture. Parent need not reimburse any
expense or indemnify against any loss or liability the Trustee Incurs through
the Trustee's negligence or bad faith.


                                       54












        To secure payment of Parent's obligations under this Section 7.07, the
Trustee shall have a Lien prior to the Exchange Debentures on all money or
property the Trustee holds or collects, except that held in trust to pay
principal of, and premium, if any, interest, if any, on, particular Exchange
Debentures. Such Lien shall survive the satisfaction and discharge of this
Indenture.

        When the Trustee Incurs expenses or renders services after an Event of
Default specified in Section 6.01(a)(vii) occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute administrative expenses under any Bankruptcy
Law without any need to demonstrate substantial contribution under Bankruptcy
Law.

        SECTION 7.08. Replacement of Trustee. A resignation or removal of the
Trustee and appointment of a successor Trustee shall become effective only upon
the successor Trustee's acceptance of appointment as provided in this Section
7.08.

        The Trustee may resign and be discharged from the trust hereby created
by so notifying Parent in writing. The Holders of a majority in aggregate
principal amount of the then outstanding Exchange Debentures may remove the
Trustee by so notifying the Trustee and Parent in writing. Parent may remove the
Trustee if: (i) the Trustee fails to comply with Section 7.10; (ii) the Trustee
is adjudged a bankrupt or an insolvent or an order for relief is entered with
respect to the Trustee under any Bankruptcy Law; (iii) a Custodian or public
officer takes charge of the Trustee or its property or (iv) the Trustee becomes
incapable of performing the services of the Trustee hereunder.

        If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, Parent shall promptly appoint a successor
Trustee, provided that within one year after such appointment the Holders of a
majority in aggregate principal amount of the then outstanding Exchange
Debentures may appoint a successor Trustee to replace any successor Trustee
appointed by Parent.

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

        If the Trustee fails to comply with Section 7.10, any Holder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

        A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to Parent. Thereupon, the resignation or
removal of the retiring Trustee shall become effective and the successor Trustee
shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its appointment to
Holders. The retiring Trustee shall promptly transfer all property it holds as
Trustee to the


                                       55












successor Trustee, subject to its rights under Section 7.07 and provided that
all sums owing to the retiring Trustee hereunder have been paid. Notwithstanding
replacement of the Trustee pursuant to this Section 7.08, Parent's obligations
under Section 7.07 shall continue for the retiring Trustee's benefit with
respect to expenses and liabilities relating to the retiring Trustee's
activities prior to being replaced.

        SECTION 7.09. Successor Trustee by Merger, Etc. If the Trustee
consolidates, merges or converts into, or transfers all or substantially all of
its corporate trust business to, another corporation, subject to Section 7.10,
the successor corporation without any further act shall be the successor
Trustee.

        SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all
times (i) be a corporation organized and doing business under the laws of the
United States of America, of any state thereof, or the District of Columbia
authorized under such laws to exercise corporate trustee power, (ii) be subject
to supervision or examination by federal or state authority, (iii) have a
combined capital and surplus of at least $50 million as set forth in its most
recent published annual report of condition, and (iv) satisfy the requirements
of sections 310(a)(1), (2) and (5) and 310(b) of the TIA.

        SECTION 7.11. Preferential Collection of Claims Against Company. The
Trustee is subject to section 311(a) of the TIA, excluding any creditor
relationship listed in section 311(b) of the TIA. A Trustee who has resigned or
been removed shall be subject to section 311(a) of the TIA to the extent
indicated therein.

                                     ARTICLE 8

                              DISCHARGE OF INDENTURE

        SECTION 8.01. Discharge of Liability on Exchange Debentures; Defeasance.
(a) Subject to Sections 8.01(c) and 8.06, this Indenture shall cease to be of
any further effect after (i) either Parent has delivered to the Trustee all
outstanding Exchange Debentures (other than Exchange Debentures replaced
pursuant to Section 2.08) for cancellation or all outstanding Exchange
Debentures have become due and payable and Parent has irrevocably deposited with
the Trustee or a Paying Agent money and/or Government Securities in an amount
sufficient (without reinvestment thereof) to pay when due all principal of,
premium, if any, and interest on, all outstanding Exchange Debentures (other
than Exchange Debentures replaced pursuant to Section 2.08), and (ii) Parent
pays all other sums payable under this Indenture.

        (b) Subject to Sections 8.01(c), 8.02, and 8.06, Parent at any time may
terminate (i) all its obligations under this Indenture and the Exchange
Debentures ("LEGAL DEFEASANCE"), or (ii) its obligations under Sections 4.02,
4.03, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.12, 4.13, 4.14 and

                                       56












5.01 ("COVENANT DEFEASANCE"). Parent may exercise Legal Defeasance
notwithstanding its prior exercise of Covenant Defeasance.

        If Parent exercises Legal Defeasance, payment of the Exchange Debentures
may not be accelerated because of an Event of Default. If Parent exercises
Covenant Defeasance, payment of the Exchange Debentures may not be accelerated
because of an Event of Default specified in 6.01 (a)(iii), (iv), (v), (vi), or
(vii).

        Upon satisfaction of the conditions set forth in Section 8.02 and upon
Parent's request (and at Parent's expense), the Trustee shall acknowledge in
writing the discharge of those obligations that Parent has terminated.

        (c) Notwithstanding Sections 8.01(a) and (b), Parent's obligations under
Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 4.01, 4.04, 7.07, 7.08, 8.04,
8.05, and 8.06, and the obligations of the Trustee and the Paying Agent under
Section 8.04 shall survive until the Exchange Debentures have been paid in full.
Thereafter, Parent's obligations under Sections 7.07 and 8.05 and the
obligations of Parent, Trustee and Paying Agent under Section 8.04 shall
survive.

        SECTION 8.02.  Conditions to Defeasance.  Parent may exercise either
Legal Defeasance or Covenant Defeasance only if:

               (i) Parent irrevocably deposits with the Trustee, in trust, for
          the benefit of the Holders of the Exchange Debentures, cash in U.S.
          dollars, non-callable Government Securities, or a combination thereof,
          in such amounts as will be sufficient, (x) in the opinion of a
          nationally recognized firm of independent public accountants, to pay
          the principal of, premium, if any, and interest on the outstanding
          Exchange Debentures on the stated maturity or the date such payments
          are due in accordance with the terms of the Exchange Debentures or on
          the applicable, redemption date, as the case may be, and (y) in the
          opinion of Parent as stated in an Officers' Certificate to pay Trustee
          Expenses. In addition, Parent specifies whether the Exchange

          redemption date,

               (ii) in the case of Legal Defeasance, Parent shall have delivered
          to the Trustee (1) an Opinion of Counsel reasonably acceptable to the
          Trustee confirming that (x) Parent has received from, or there has
          been published by, the Internal Revenue Service a ruling or (y) 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 will confirm that, the Holders of the
          outstanding Exchange Debentures 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, (2) an Opinion of
          Counsel to the effect that (x) the deposit of the trust funds does not
          violate the Investment Company Act of 1940 and (y) after the period
          ending on


                                       57












          the 123rd day after the date of deposit the trust funds will not be
          subject to the effect of Section 547 of the United States Bankruptcy
          Code or Section 15 of the New York Debtor and Creditor Law in a case
          commenced by or against Parent under either such statute,

               (iii) in the case of Covenant Defeasance, Parent shall have
          delivered to the Trustee (1) an Opinion of Counsel in the United
          States reasonably acceptable to the Trustee confirming that the
          Holders of the outstanding Exchange Debentures 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 at the same times as would have
          been the case if such Covenant Defeasance had not occurred, (2) an
          Opinion of Counsel to the effect that (x) the deposit of the trust
          funds does not violate the Investment Company Act of 1940 and (y)
          after the period ending on the 123rd day after the date of deposit the
          trust funds will not be subject to the effect of Section 547 of the
          United States Bankruptcy Code or Section 15 of the New York Debtor and
          Creditor Law in a case commenced by or against Parent under either
          such statute,

               (iv) 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 Events of Default from bankruptcy or insolvency
          events are concerned, at any time in the period ending on the 123rd
          day after the date of deposit,

               (v) such Legal Defeasance or Covenant Defeasance shall not result
          in a breach or violation of, or constitute a Default under any
          material agreement or instrument (other than this Indenture) to which
          Parent or any of its Subsidiaries is a party or by which Parent or any
          of its Subsidiaries is bound,

               (vi) Parent shall have delivered to the Trustee an Officers'
          Certificate stating that the deposit was not made by Parent with the
          intent of preferring the Holders of Exchange Debentures over the other
          creditors of Parent with the intent of defeating, hindering, delaying
          or defrauding creditors of Parent or others and

               (vii) Parent shall have delivered to the Trustee an Officers'
          Certificate and an Opinion of Counsel, each stating that all
          conditions precedent relating to the Legal Defeasance or the Covenant
          Defeasance have been complied with.

        SECTION 8.03. Application of Trust Money. The Trustee or Paying Agent
shall hold in trust money and/or Government Securities deposited with it
pursuant to this Article 8. The Trustee or Paying Agent shall apply the
deposited money and the money from Government Securities in accordance with this
Indenture to the payment of principal of, and premium, if any, or interest on,
the Exchange Debentures. Money deposited with the Trustee or a Paying Agent
pursuant to this Article 8 shall not be subject to the provisions of Article 10.


                                       58












        SECTION 8.04. Repayment to Parent. After the Exchange Debentures have
been paid in full, the Trustee and the Paying Agent shall promptly turn over to
Parent any excess money or Exchange Debentures held by them.

        Any money deposited with the Trustee or a Paying Agent pursuant to this
Article 8 for the payment of the principal of, premium, if any, or interest on,
any Exchange Debenture, that remains unclaimed for two years after becoming due
and payable shall be paid to Parent on its request; and the Holder of such
Exchange Debenture, shall thereafter, as an unsecured general creditor, look
only to Parent for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such money shall cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of Parent cause to be published once, in The New York Times
and The Wall Street Journal (National Edition), notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such notification or publication, any unclaimed balance
of such money then remaining will be repaid to Parent.

        SECTION 8.05. Indemnity for Government Securities. Parent shall pay and
shall indemnify the Trustee and any Paying Agent against any tax, fee or other
charge imposed on or assessed against cash and/or Government Securities
deposited with it pursuant to this Article 8 or the principal and interest
received on such cash and/or Government Securities.

        SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is unable to
apply any money or Government Securities in accordance with this Article 8 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, Parent's Obligations under this Indenture and the Exchange
Debentures shall be revived and reinstated as though no deposit had occurred
pursuant to this Article 8 until such time as the Trustee or Paying Agent is
permitted to apply all such money or Government Securities in accordance with
this Article 8; provided, however, that if Parent has made any payment of
principal of, or premium, if any, or interest, if any, on, any Exchange
Debentures because of the reinstatement of its Obligations under this Indenture
and the Exchange Debentures, Parent shall be subrogated to the Holders' rights
to receive such payment from the money or Government Securities held by the
Trustee or Paying Agent.

                                     ARTICLE 9

                                    AMENDMENTS

        SECTION 9.01. Amendments and Supplements Permitted without Consent of
Holders. (a) Notwithstanding Section 9.02, Parent and the Trustee may amend or
supplement this Indenture or the Exchange Debentures without the consent of any
Holder to: (i) cure any ambiguity, defect or inconsistency; (ii) provide for
uncertificated Exchange Debentures in


                                       59












addition to or in place of Certificated Exchange Debentures; (iii) provide for
the assumption of the obligations to the Holders of Parent, in the event of a
merger or consolidation; (iv) make any change that (1) would provide any
additional rights or benefits to Holders or (2) does not adversely affect the
legal rights under this Indenture of any Holder; or (v) comply with the
requirements of the SEC in order to effect or maintain the qualification of this
Indenture under the TIA.

        (b) Upon Parent's request, after receipt by the Trustee of a resolution
of the Board of Directors of Parent authorizing the execution of any amended or
supplemental indenture and the documents described in Section 9.06, the Trustee
shall join with Parent in the execution of any amended or supplemental indenture
authorized or permitted by the terms of this Indenture, but the Trustee shall
not be obligated to enter into an amended or supplemental indenture that
adversely affects its own rights, duties or immunities under this Indenture or
otherwise.

        SECTION 9.02. Amendments and Supplements Requiring Consent of Holders.
(a) Except as otherwise provided in Sections 9.01(a), this Indenture and the
Exchange Debentures may be amended or supplemented with the written consent of
the Holders of at least a majority in aggregate principal amount of the Exchange
Debentures then outstanding (including consents obtained in connection with a
tender offer or exchange offer for the Exchange Debentures), and any existing
Default or Event of Default or compliance with any provision of this Indenture
or the Exchange Debentures may be waived (other than any continuing Default or
Event of Default in the payment of the principal of, premium, if any, or
interest on the Exchange Debentures) with the consent of Holders of at least a
majority in aggregate principal amount of the then outstanding Exchange
Debentures (including consents obtained in connection with a tender offer or
exchange offer for the Exchange Debentures); provided that:

               (i) no such modification or amendment may, without the consent of
          the Holders of 75% in aggregate principal amount of such Exchange
          Debentures then outstanding, amend or modify the obligations of Parent
          under Section 4.12 (or the definitions related thereto) that could
          adversely affect the rights of any Holder of the Exchange Debentures;
          and

               (ii) without the consent of each Holder affected, Parent and the
          Trustee may not: (w) extend the maturity of any Exchange Debentures;
          (x) affect the terms of any scheduled payment of interest on or
          principal of the Exchange Debentures (including without limitation any
          redemption provisions); (y) take any action that would subordinate the
          Exchange Debentures to any other Indebtedness of Parent (except as
          provided in Article 10), or otherwise affect the ranking of the
          Exchange Debentures; or (z) reduce the percentage of Holders necessary
          to consent to an amendment, supplement or waiver to this Indenture.

        (b) It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment or waiver,
but it shall be sufficient if


                                       60












such consent approves the substance thereof. After an amendment, supplement or
waiver under this Section becomes effective, Parent shall mail to each Holder
affected thereby a notice briefly describing the amendment, supplement or
waiver. Any failure of Parent to mail such notice, or any defect therein, shall
not, however, in any way impair or affect the validity of any such amended or
supplemental indenture or waiver.

        SECTION 9.03. Compliance with TIA. Every amendment or supplement to this
Indenture or the Exchange Debentures shall be set forth in an amended
supplemental indenture that complies with the TIA as then in effect.

        SECTION 9.04. Revocation and Effect of Consents. (a) Until an amendment,
supplement or waiver becomes effective, a consent to it by a Holder of an
Exchange Debenture is a continuing consent by the Holder and every subsequent
Holder of an Exchange Debenture or portion of an Exchange Debenture that
evidences the same Indebtedness as the consenting Holder's Exchange Debenture,
even if notation of the consent is not made on any Exchange Debenture. However,
any such Holder or subsequent Holder may revoke the consent as to his or her
Exchange Debenture or portion of an Exchange Debenture if the Trustee receives
the notice of revocation before the date on which the Trustee receives an
Officers' Certificate certifying that the Holders of the requisite principal
amount of Exchange Debentures have consented to the amendment, supplement or
waiver.

        (b) Parent may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders of Exchange Debentures entitled to consent to
any amendment or waiver. If a record date is fixed, then notwithstanding the
provisions of the immediately preceding paragraph, those Persons who were
Holders of Exchange Debentures at such record date (or their duly designated
proxies), and only those Persons, shall be entitled to consent to such amendment
or waiver or to revoke any consent previously given, whether or not such Persons
continue to be Holders of Exchange Debentures after such record date. No consent
shall be valid or effective for more than 90 days after such record date unless
consents from Holders of the principal amount of Exchange Debentures required
hereunder for such amendment or waiver to be effective shall have also been
given and not revoked within such 90-day period.

        (c) After an amendment or waiver becomes effective, it shall bind every
Holder, unless it is of the type described in clause (ii) of Section 9.02(a), in
which case the amendment or waiver shall only bind each Holder that consented to
it and every subsequent holder of an Exchange Debenture that evidences the same
debt as the consenting Holder's Exchange Debenture.

        SECTION 9.05. Notation or Exchange of Exchange Debentures. The Trustee
may place an appropriate notation about an amendment, supplement or waiver on
any Exchange Debenture thereafter authenticated. Parent in exchange for all
Exchange Debentures may issue and the Trustee shall authenticate new Exchange
Debentures that reflect the amendment, supplement or


                                       61












waiver. Failure to make the appropriate notation or issue a new Exchange
Debenture shall not affect the validity and effect of such amendment, supplement
or waiver.

        SECTION 9.06. Trustee Protected. The Trustee shall sign any amendment or
supplemental indenture authorized pursuant to this Article 9 if the amendment
does not adversely affect the rights, duties, liabilities or immunities of the
Trustee. If it does, the Trustee may, but need not, sign it. In signing such
amendment or supplemental indenture, the Trustee shall be entitled to receive
and, subject to Section 7.01, shall be fully protected in relying upon, an
Officers' Certificate and Opinion of Counsel pursuant to Sections 11.04 and
11.05 as conclusive evidence that such amendment or supplemental indenture is
authorized or permitted by this Indenture, that it is not inconsistent herewith,
and that it will be valid and binding upon Parent in accordance with its terms.
Parent may not sign an amendment or supplemental indenture until the Board of
Directors of the Parent approves it.

                                    ARTICLE 10

                                   SUBORDINATION

        SECTION 10.01. Agreement to Subordinate. Parent agrees, and each Holder
by accepting an Exchange Debenture agrees, that the payment by Parent of
principal of, and premium, if any, and interest on the Exchange Debentures are
subordinated to the prior payment in full in cash when due of the principal of,
and premium, if any, and accrued and unpaid interest on and all other amounts
owing in respect of, all existing and future Senior Indebtedness of Parent.

        SECTION 10.02. Liquidation; Dissolution; Bankruptcy. (a) Upon any
payment or distribution to creditors of the assets of Parent of any kind or
character in a total or partial liquidation or dissolution of Parent or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to Parent, whether voluntary or involuntary (including any assignment
for the benefit of creditors and proceedings for marshaling of assets and
liabilities of Parent) (an "INSOLVENCY OR LIQUIDATION PROCEEDING"), the holders
of all Senior Indebtedness of Parent then outstanding will be entitled to
payment in full in cash (including interest accruing subsequent to the filing of
petition of bankruptcy or insolvency at the rate specified in the document
relating to the applicable Senior Indebtedness, whether or not such interest is
an allowed claim enforceable against Parent under applicable law) before the
Holders of Exchange Debentures are entitled to receive any payment (other than
payments made from a trust previously established pursuant to provisions
described Section 8.02) on or with respect to the Exchange Debentures and until
all Senior Indebtedness receives payment in full in cash, any distribution to
which the Holders of Exchange Debentures would be entitled will be made to
holders of Senior Indebtedness.

        (b) Notwithstanding anything to the contrary in Section 10.02, Holders
of Exchange Debentures may continue to receive payments from the trust
established pursuant to Article 8.


                                       62













        SECTION 10.03. No Payment on Exchange Debentures in Certain
Circumstances. (a) Upon the occurrence of any default in the payment of any
principal of or interest on or other amounts due on any Designated Senior
Indebtedness of Parent (a "PAYMENT DEFAULT"), no payment of any kind or
character shall be made by Parent (or by any other Person on its or their
behalf) with respect to the Exchange Debentures unless and until (i) such
Payment Default shall have been cured or waived in accordance with the
instruments governing such Indebtedness or shall have ceased to exist, (ii) such
Designated Senior Indebtedness has been discharged or paid in full in cash in
accordance with the instruments governing such Indebtedness or (iii) the
benefits of this sentence have been waived by the holders of such Designated
Senior Indebtedness or their representative, including, if applicable, the
Agents, immediately after which Parent must resume making any and all required
payments, including missed payments, in respect of its obligations under the
Exchange Debentures.

        (b) Upon (i) the occurrence and continuance of an event of default
(other than a Payment Default) relating to Designated Senior Indebtedness, as
such event of default is defined therein or in the instrument or agreement under
which it is outstanding, which event of default, pursuant to the instruments
governing such Designated Senior Indebtedness, entitles the holders (or a
specified portion of the holders) of such Designated Senior Indebtedness or
their designated representative to immediately accelerate without further notice
(except such notice as may be required to effect such acceleration) the maturity
of such Designated Senior Indebtedness (whether or not such acceleration has
actually occurred) (a "NON-PAYMENT DEFAULT") and (ii) the receipt by the Trustee
and Parent from the trustee or other representative of holders of such
Designated Senior Indebtedness of written notice (a "PAYMENT BLOCKAGE NOTICE")
of such occurrence, no payment is permitted to be made by Parent (or by any
other Person on its or their behalf) in respect of the Exchange Debentures for a
period (a "PAYMENT BLOCKAGE PERIOD") commencing on the date of receipt by the
Trustee of such notice and ending on the earliest to occur of the following
events (subject to any blockage of payments that may then be in effect due to a
Payment Default on Designated Senior Indebtedness): (w) such Non-payment Default
has been cured or waived or has ceased to exist; (x) a 179-consecutive-day
period commencing on the date such written notice is received by the Trustee has
elapsed; (y) such Payment Blockage Period has been terminated by written notice
to the Trustee from the Trustee or other representative of holders of such
Designated Senior Indebtedness, whether or not such Non-payment Default has been
cured or waived or has ceased to exist; and (z) such Designated Senior
Indebtedness has been discharged or paid in full in cash, immediately after
which, in the case of clause (w), (x), (y) or (z), Parent must resume making any
and all required payments, including missed payments, in respect of its
obligations under the Exchange Debentures. Notwithstanding the foregoing, (A)
not more than one Payment Blockage Period may be commenced in any period of 365
consecutive days and (B) no default or event of default with respect to the
Designated Senior Indebtedness of Parent that was the subject of a Payment
Blockage Notice which existed or was continuing on the date of the giving of any
Payment Blockage Notice shall be or serve as the basis for the giving of a
subsequent Payment Blockage Notice whether or not within a period of 365
consecutive days unless such default or event of


                                       63












default shall have been cured or waived for a period of at least 90 consecutive
days after such date. Notwithstanding anything in this Indenture to the
contrary, there must be 180 consecutive days in any 365-day period in which no
Payment Blockage Period is in effect.

        (c) Notwithstanding the foregoing, Holders of Exchange Debentures may
receive and retain Permitted Junior Securities and payment from the money or the
proceeds held in any defeasance trust described under Article 8, and no such
receipt or retention will be contractually subordinated in right of payment to
any Senior Indebtedness or subject to the restrictions described in this Article
10.

        SECTION 10.04. Acceleration of Exchange Debentures. If payment of the
Exchange Debentures is accelerated because of an Event of Default, Parent shall
promptly notify the Credit Facility Agent and each holder of the Senior
Indebtedness of Parent of the acceleration.

        SECTION 10.05. When Distributions Must Be Paid Over. In the event that
any payment or distribution of assets of Parent, whether in cash, property or
securities, shall be received by the Trustee or the Holders of Exchange
Debentures at a time when such payment or distribution is prohibited by this
Article 10, such payment or distribution shall be segregated from other funds or
assets and held in trust for the benefit of the holders of Senior Indebtedness
of Parent and shall be paid or delivered by the Trustee or such Holders, as the
case may be, to the holders of the Senior Indebtedness of the Parent remaining
unpaid or unprovided for or their representative or representatives, or to the
trustee or trustees under any indenture pursuant to which any instruments
evidencing any of such Senior Indebtedness of Parent may have been issued,
ratably according to the aggregate amounts remaining unpaid on account of the
Senior Indebtedness of Parent held or represented by each, for application to
the payment of all Senior Indebtedness of Parent, remaining unpaid, to the
extent necessary to pay or to provide for the payment in full in cash of all
such Senior Indebtedness after giving effect to any concurrent payment or
distribution to the holders of such Senior Indebtedness.

        With respect to the holders of Senior Indebtedness of Parent, the
Trustee undertakes to perform only such obligations on its part as are
specifically set forth in this Article 10, and no implied covenants or
obligations with respect to any holders of the Senior Indebtedness of Parent
shall be read into this Indenture against the Trustee. The Trustee shall not be
deemed to owe any fiduciary duty to the holders of the Senior Indebtedness of
Parent and shall not be liable to any holders of such Senior Indebtedness if the
Trustee shall pay over or distribute to, or on behalf of, Holders or Parent or
any other Person, money or assets to which any holders of such Senior
Indebtedness are entitled pursuant to this Article 10, except if such payment is
made at a time when a Trust Officer has knowledge that the terms of this Article
10 prohibit such payment.

        SECTION 10.06. Notice. Neither the Trustee nor the Paying Agent shall at
any time be charged with the knowledge of the existence of any facts that would
prohibit the making of any payment to or by the Trustee or Paying Agent under
this Article 10, unless and until the Trustee or Paying Agent shall have
received written notice thereof from Parent or one or more holders of


                                       64












the Senior Indebtedness of Parent or a Representative of any holders of such
Senior Indebtedness; and, prior to the receipt of any such written notice, the
Trustee or Paying Agent shall be entitled to assume conclusively that no such
facts exist. The Trustee shall be entitled to rely on the delivery to it of
written notice by a Person representing itself to be a holder of the Senior
Indebtedness of Parent (or a Representative thereof) to establish that such
notice has been given.

        Parent shall promptly notify the Trustee and the Paying Agent in writing
of any facts it knows that would cause a payment of principal of, or premium, if
any, or interest on, the Exchange Debentures or any other Obligation in respect
of the Exchange Debentures to violate this Article 10, but failure to give such
notice shall not affect the subordination of the Exchange Debentures to the
Senior Indebtedness of Parent provided in this Article 10 or the rights of
holders of such Senior Indebtedness under this Article 10.

        SECTION 10.07. Subrogation. After all Senior Indebtedness of Parent has
been paid in full in cash and until the Exchange Debentures are paid in full,
Holders shall be subrogated (equally and ratably with all other Indebtedness
pari-passu with the Exchange Debentures) to the rights of holders of such Senior
Indebtedness to receive distributions applicable to such Senior Indebtedness to
the extent that distributions otherwise payable to the Holders have been applied
to the payment of such Senior Indebtedness A distribution made under this
Article 10 to holders of the Senior Indebtedness of Parent that otherwise would
have been made to Holders is not, as between Parent and Holders, a payment by
Parent on its Senior Indebtedness.

        SECTION 10.08. Relative Rights. This Article 10 defines the relative
rights of Holders and holders of the Senior Indebtedness of Parent. Nothing in
this Indenture shall: (1) impair, as between Parent and Holders, the Obligations
of Parent, which are absolute and unconditional, to pay principal of, and
premium, if any, and interest on the Exchange Debentures in accordance with
their terms; (2) affect the relative rights of Holders and the creditors of
Parent other than their rights in relation to holders of the Senior Indebtedness
of Parent; or (3) 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 the Senior Indebtedness of Parent to receive distributions and
payments otherwise payable to Holders.

        Nothing contained in this Article 10 or elsewhere in this Indenture or
in any Exchange Debenture is intended to or shall impair, as between Parent and
the Holders, the Obligations of Parent, which are absolute and unconditional, to
pay to the Holders the principal of, and premium, if any, and interest on the
Exchange Debentures as and when the same shall become due and payable in
accordance with their terms, or is intended to or shall affect the relative
rights of the Holders and creditors of Parent other than the holders of the
Senior Indebtedness of Parent, nor shall anything herein or therein prevent the
Trustee or any Holder from exercising all remedies otherwise permitted by
applicable law upon Default under this Indenture, subject to the rights, if any,
under this Article 10 of the holders of such Senior Indebtedness.


                                       65












        The failure to make a payment on account of principal of, or interest on
the Exchange Debentures by reason of any provision of this Article 10 shall not
be construed as preventing the occurrence of an Event of Default under Section
6.01.

        SECTION 10.09. Parent and Holders May Not Impair Subordination. (a) No
right of any holder of the Senior Indebtedness of Parent to enforce the
subordination as provided in this Article 10 shall at any time or in any way be
prejudiced or impaired by any act or failure to act by Parent or by any
noncompliance by Parent with the terms, provisions and covenants of this
Indenture or the Exchange Debentures or any other agreement regardless of any
knowledge thereof with which any such holder may have or be otherwise charged.

        (b) Without in any way limiting Section 10.09(a), the holders of any
Senior Indebtedness of Parent may, at any time and from time to time to the
extent not otherwise prohibited by this Indenture, without the consent of or
notice to any Holders, without incurring any liabilities to any Holder and
without impairing or releasing the subordination and other benefits provided in
this Indenture or the Holders' obligations to the holders of such Senior
Indebtedness, even if any Holder's right of reimbursement or subrogation or
other right or remedy is affected, impaired or extinguished thereby, do any one
or more of the following: (i) amend, renew, exchange, extend, modify, increase
or supplement in any manner such Senior Indebtedness or any instrument
evidencing or guaranteeing or securing such Senior Indebtedness or any agreement
under which such Senior Indebtedness is outstanding (including, but not limited
to, changing the manner, place or terms of payment or changing or extending the
time of payment of, or renewing, exchanging, amending, increasing or altering,
(x) the terms of such Senior Indebtedness, (y) any security for, or any
Guarantee of, such Senior Indebtedness, (z) any liability of any obligor on such
Senior Indebtedness (including any guarantor) or any liability Incurred in
respect of such Senior Indebtedness) (ii) sell, exchange, release, surrender,
realize upon, enforce or otherwise deal with in any manner and in any order any
property pledged, mortgaged or otherwise securing such Senior Indebtedness or
any liability of any obligor thereon, to such holder, or any liability Incurred
in respect thereof; (iii) settle or compromise any such Senior Indebtedness or
any other liability of any obligor of such Senior Indebtedness to such holder or
any security therefor or any liability Incurred in respect thereof and apply any
sums by whomsoever paid and however realized to any liability (including,
without limitation, payment of any of the Senior Indebtedness) in any manner or
order; and (iv) fail to take or to record or otherwise perfect, for any reason
or for no reason, any lien or security interest securing such Senior
Indebtedness by whomsoever granted, exercise or delay in or refrain from
exercising any right or remedy against any obligor or any guarantor or any other
Person, elect any remedy and otherwise deal freely with any obligor and any
security for such Senior Indebtedness or any liability of any obligor to the
holders of such Senior Indebtedness or any liability Incurred in respect of such
Senior Indebtedness.

        SECTION 10.10.  Distribution or Notice to Representative.  Whenever a
distribution is to be made, or a notice given, to holders of Senior Indebtedness
of Parent, the distribution may be made and the notice given to their
Representative, if any.  If any payment or distribution of


                                       66












Parent's assets is required to be made to holders of any of the Senior
Indebtedness of Parent pursuant to this Article 10, the Trustee and the Holders
shall be entitled to rely upon any order or decree of any court of competent
jurisdiction, or upon any certificate of a Representative of such Senior
Indebtedness or a Custodian, in ascertaining the holders of such Senior
Indebtedness entitled to participate in any such payment or distribution, the
amount to be paid or distributed to holders of such Senior Indebtedness and all
other facts pertinent to such payment or distribution or to this Article 10.

        SECTION 10.11. Rights of Trustee and Paying Agent. The Trustee or Paying
Agent may continue to make payments on the Exchange Debentures unless prior to
any payment date it has received written notice of facts that would cause a
payment of principal of, or premium, if any, or interest on the Exchange
Debentures to violate this Article 10. Only Parent, a Representative of Senior
Indebtedness, or a holder of Senior Indebtedness that has no Representative may
give such notice.

        To the extent permitted by the TIA, the Trustee in its individual or any
other capacity may hold Indebtedness of Parent (including Senior Indebtedness)
with the same rights it would have if it were not Trustee. Any Agent may do the
same with like rights.

        SECTION 10.12. Authorization to Effect Subordination. Each Holder of an
Exchange Debenture by its acceptance thereof authorizes and directs the Trustee
on its behalf to take such action as may be necessary or appropriate to
effectuate the subordination as provided in this Article 10, and appoints the
Trustee as such Holder's attorney-in-fact for any and all such purposes
(including, without limitation, the timely filing of a claim for the unpaid
balance of the Exchange Debenture that such Holder holds in the form required in
any Insolvency or Liquidation Proceeding and causing such claim to be approved).

        If a proper claim or proof of debt in the form required in such
proceeding is not filed by or on behalf of all Holders prior to 30 days before
the expiration of the time to file such claims or proofs, then the holders or a
Representative of any Senior Indebtedness of Parent are hereby authorized, and
shall have the right (without any duty), to file an appropriate claim for and on
behalf of the Holders.

        SECTION 11.01. Trust Indenture Act Controls. If any provision of this
Indenture limits, qualifies, or conflicts with the duties imposed by operation
of Section 318(c) of the TIA, the imposed duties shall control.

        SECTION 11.02. Notices. Any notice or communication by Parent or the
Trustee to the other is duly given if in writing and delivered in person, mailed
by registered or certified mail, postage prepaid, return receipt requested or
delivered by telecopier or overnight air courier guaranteeing next day delivery
to the other's address:

        Any notice or communication to a Holder shall be mailed by first-class
mail to his or her address shown on the register maintained by the Registrar.
Failure to mail a notice or communication to a Holder or any defect in it shall
not affect its sufficiency with respect to other Holders. If a notice or
communication is mailed in the manner provided above within the time prescribed,
it is duly given, whether or not the addressee receives it. If Parent mails a
notice or communication to Holders, it shall mail a copy to the Trustee and each
Agent at the same time.

        SECTION 11.03. Communication by Holders with Other Holders. Holders may
communicate pursuant to section 312(b) of the TIA with other Holders with
respect to their rights under this Indenture or the Exchange Debentures. Parent,
the Trustee, the Registrar and any other Person shall have the protection of
section 312(c) of the TIA.

        SECTION 11.04. Certificate and Opinion As to Conditions Precedent. Upon
any request or application by Parent to the Trustee to take any action under
this Indenture, Parent shall furnish to the Trustee: (a) an Officers'
Certificate (which shall include the statements set forth in Section 11.05)
stating that, in the opinion of the signers, all conditions precedent and
covenants,


                                       68












if any, provided for in this Indenture relating to the proposed action have been
complied with; and (b) an Opinion of Counsel (which shall include the statements
set forth in Section 11.05) stating that, in the opinion of such counsel, all

                                      A-4













'SS' 77aaa-77bbbb) as in effect on the date of the original issuance of the
Exchange Debentures (the "Trust Indenture Act"). The Exchange Debentures are
subject to, and qualified by, all such terms, certain of which are summarized
herein, and Holders are referred to the Indenture and the Trust Indenture Act
for a statement of such terms (all capitalized terms not defined herein shall

          interest if any thereon to the applicable redemption date, if redeemed
          during the twelve-month period beginning on March 1 of the years

               (c) If less than all of the Exchange Debentures are to be
          redeemed at any time, selection of the Exchange Debentures to be
          redeemed will be made by the Trustee from among the outstanding
          Exchange Debentures on a pro rata basis, by lot or by any other method
          permitted in the Indenture. Notice of redemption will be mailed at
          least 30 days but not more than 60 days before the redemption date to
          each holder whose Exchange Debentures are to be redeemed at the
          registered address of such holder. On and after the redemption date,
          interest will cease to accrue on the Exchange Debentures or portions
          thereof called for redemption.

Trigger Date or Asset Sale Trigger Date, Parent shall mail to the Trustee (who
shall mail to each Holder) a notice stating certain details as set forth in
Section 3.08 of the Indenture in connection with the Offer that Parent is
obligated under the Indenture to make to Holders in such circumstances.

               (b) Holders may tender all or, subject to Section 8 below, any
          portion of their Notes by completing the attachment hereto entitled
          "OPTION OF HOLDER TO ELECT PURCHASE" in an Offer.

                                      A-5













               (c) Upon a Change of Control, any Holder of Exchange Debentures
          will have the right to cause Parent to purchase the Exchange
          Debentures of such Holder, in whole or in part in integral multiples
          of aggregate principal amount of $10,000, at a purchase price in cash
          equal to 101% of the principal amount thereof plus accrued and unpaid
          interest, if any, to the date of repurchase, as provided in, and
          subject to the terms of the Indenture.

               (d) Upon there being at least $5,000,000 in Excess Proceeds
          relating to one or more Asset Sales, any Holder of Exchange Debentures
          will have the right to cause Parent to purchase the Exchange
          Debentures of such Holder, in whole or in part in integral multiples
          of aggregate principal amount of $10,000, at a purchase price in cash
          equal to 100% of the principal amount thereof plus accrued and unpaid
          interest, if any, to the date such Net Proceeds Offer is consummated,
          as provided in, and subject to the terms of the Indenture.

               (e) Promptly after consummation of an Offer, (i) the Paying Agent
          shall mail or wire transfer, if permitted under the Indenture, to each
          Holder of Exchange Debentures or portions thereof accepted for payment
          an amount equal to Change of Control Price or Offered Price, as the
          case may be, (ii) with respect to any tendered Exchange Debenture not
          accepted for payment in whole or in part, the Trustee shall return
          such Exchange Debenture to the Holder thereof, and (iii) with respect
          to any Exchange Debenture accepted for payment in part, Parent shall
          issue and the Trustee shall authenticate and mail to each such Holder
          a new Exchange Debenture equal in principal amount to the unpurchased
          portion of the tendered Exchange Debenture.

               (f) Parent will (i) announce the results of the Offer to Holders
          on or as soon as practicable after the Purchase Date, and (ii) comply
          with Rule 14e-1 under the Securities Exchange Act of 1934, as amended,
          and any other securities laws and regulations to the extent applicable
          to any Offer.

         7. EXCHANGE DEBENTURES TO BE REDEEMED OR PURCHASED. The Exchange
Debentures may be redeemed or purchased in part, but only in multiples of
$10,000 principal amount unless all Exchange Debentures held by a Holder are to
be redeemed or purchased. On or after any date on which Exchange Debentures are
redeemed or purchased, interest ceases to accrete or accrue, as the case may be,
on the Exchange Debentures or portions thereof called for redemption or accepted
for purchase on such date.

         8. DENOMINATIONS, TRANSFER, EXCHANGE. The Exchange Debentures are in
registered form, without coupons, in denominations of $10,000 principal amount
of maturity and integral multiples thereof. The transfer of Exchange Debentures
may be registered and Exchange Debentures may be exchanged as provided in the
Indenture. Holders seeking to transfer or exchange their Exchange Debentures may
be required, among other things, to furnish appropriate endorsements and
transfer documents and to pay any taxes and fees required by law or permitted


                                      A-6














by the Indenture. The Registrar need not exchange or register the transfer of
any Exchange Debenture or portion of an Exchange Debenture selected for
redemption or tendered pursuant to an Offer. Neither the Trustee nor the
Registrar shall be required to issue, register the transfer of or exchange any
Exchange Debenture (i) to register the transfer of or exchange any Exchange
Debenture selected for redemption, (ii) to register the transfer of or exchange
any Exchange Debenture for a period of 15 days before the mailing of a notice of
redemption and ending on the date of such mailing, or (iii) to register the
transfer or exchange of an Exchange Debenture between a record date and the next
succeeding interest payment date.

        9. PERSONS DEEMED OWNERS. The registered Holder of an Exchange Debenture
shall be treated as the owner of the Note for all purposes.

        10. AMENDMENTS AND WAIVERS. (a) Subject to certain exceptions, the
Indenture and the Exchange Debentures may be amended or supplemented with the
written consent of the Holders of at least a majority in aggregate principal
amount of the then outstanding Exchange Debentures (including consents obtained
in connection with a tender offer or exchange offer for the Exchange
Debentures), and any existing Default or Event of Default or compliance with any
provision of the Indenture or the Exchange Debentures may be waived with the
consent of the Holders of at least a majority in principal amount of the then
outstanding Exchange Debentures (including consents obtained in connection with
a tender offer or exchange offer for the Exchange Debentures); provided that:
(i) no such modification or amendment may, without the consent of the holders of
75% in aggregate principal amount of such series of Exchange Debentures then
outstanding, amend or modify the obligations of Parent under Section 4.12 of the
Indenture (or the definitions related thereto) that could adversely affect the
rights of any holder of the Exchange Debentures; and (ii) without the consent of
each holder affected, Parent and the Trustee may not: (w) extend the maturity of
any Exchange Debenture; (x) affect the terms of any scheduled payment of
interest on or principal of the Exchange Debentures (including without
limitation any redemption provisions); (y) take any action that would
subordinate the Exchange Debentures to any other Indebtedness of Parent (except
as provided in Article 10), or otherwise affect the ranking of the Exchange
Debentures; or (z) reduce the percentage of holders necessary to consent to an
amendment, supplement or waiver to this Indenture.

               (b) Notwithstanding section 10(a) above, Parent and the Trustee
          may amend or supplement the Indenture or the Exchange Debentures,
          without the consent of any Holder, to: cure any ambiguity, defect or
          inconsistency; provide for uncertificated Exchange Debentures in
          addition to or in place of certificated Exchange Debentures; provide
          for the assumption of the obligations to the Holders of Parent, in the
          event of any merger or reorganization involving the Company, that is
          permitted under Article 5 of the Indenture; make any change that would
          provide any additional rights or benefits to Holders or does not
          adversely affect the legal rights under the Indenture of any Holder;
          comply with the requirements of the SEC in order to effect or maintain
          the qualification of the Indenture under the Trust Indenture Act.


                                      A-7













        11. DEFAULTS AND REMEDIES. Events of Default include: (i) failure by
Parent to pay interest on any of the Exchange Debentures when it becomes due and
payable and the continuance of any such failure for 30 days; (ii) failure by
Parent to pay the principal or premium, if any, on any of the Exchange
Debentures when it becomes due and payable, whether at stated maturity, upon
redemption, upon acceleration or otherwise; (iii) failure by Parent to comply
with any of its agreements or covenants described under Article 5 of the
Indenture, or in respect of its obligations to make a Change of Control Offer or
a Net Proceeds Offer described in Section 4.12 and 4.13 of the Indenture,
respectively; (iv) failure by Parent to comply with any other covenant in the
Indenture and continuance of such failure for 60 days after notice of such
failure has been given to Parent by the Trustee or by the holders of at least
25% of the aggregate principal amount of the Exchange Debentures then
outstanding; (v) failure by Parent, the Company or any of its Restricted
Subsidiaries to make any payment when due at final maturity after the expiration
of any applicable grace period, in respect of any Indebtedness of Parent, the
Company or any of such Restricted Subsidiaries, or the acceleration of the
maturity of such Indebtedness by the holders thereof because of a default, with
an aggregate outstanding principal amount for all such Indebtedness under this
clause (v) of $10.0 million or more (but excluding in any event any such
Indebtedness that is paid when so due after expiration of any applicable grace
period, or upon acceleration of the maturity thereof, pursuant to any letter of
credit); (vi) one or more final, non-appealable judgments or orders that exceed
$10.0 million in the aggregate for the payment of money have been entered by a
court or courts of competent jurisdiction against Parent or any Subsidiary of
Parent and such judgment or judgments have not been satisfied, stayed, annulled
or rescinded within 60 days of being entered; (vii) certain events of
bankruptcy, insolvency or reorganization involving the Parent, the Company or
any Significant Subsidiary.

        If an Event of Default (other than an Event of Default specified in
clause (vii) above with respect to Parent), shall have occurred and be
continuing under the Indenture, the Trustee, by written notice to Parent, or the
holders of at least 25% in aggregate principal amount of the Exchange Debentures
then outstanding by written notice to Parent and the Trustee may declare all
amounts owing under the Exchange Debentures to be due and payable immediately.
Upon such declaration of acceleration, the aggregate principal of, premium, if
any, and interest on the outstanding Exchange Debentures shall immediately
become due and payable. If an Event of Default results from bankruptcy,
insolvency or reorganization with respect to Parent, all outstanding Exchange
Debentures shall become due and payable without any further action or notice. In
certain cases, the holders of a majority in aggregate principal amount of the
Exchange Debentures then outstanding may waive an existing Default or Event of
Default and its consequences, except a default in the payment of principal of,
premium, if any, and interest on the Exchange Debentures.

        In the case of an Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of Parent with the
intention of avoiding payment of the premium that Parent would have had to pay
if Parent then had elected to redeem the Exchange


                                      A-8












Debentures under the provisions of Article 3 of the Indenture and under the
Exchange Debentures, an equivalent premium shall also become and be immediately
due and payable, to the extent permitted by law, upon the acceleration of the
Exchange Debentures.

        The holders may not enforce the provisions of the Indenture or the
Exchange Debentures except as provided in the Indenture. Subject to certain
limitations, holders of a majority in principal amount of the Exchange
Debentures then outstanding may direct the Trustee in its exercise of any trust
or power; provided however, that such direction does not conflict with the terms
of the Indenture. The Trustee may withhold from the holders notice of any
continuing Default or Event of Default (except any Default or Event of Default
in payment of principal of, premium, if any, or interest on the Exchange
Debentures) if the Trustee determines that withholding such notice is in the
holders' interest.

        12. SUBORDINATION. (a) All Obligations owed under and in respect of the
Exchange Debentures are subordinated in right of payment, to the extent and in
the manner provided in Article 10 of the Indenture, to the prior payment in full
in cash of all Obligations owed under and in respect of all Senior Indebtedness
of Parent, and the subordination of the Exchange Debentures is for the benefit
of all holders of all Senior Indebtedness, whether outstanding on the Closing
Date or Incurred thereafter. Parent agrees, and each Holder by accepting an
Exchange Debenture agrees, to the subordination.

        13. TRUSTEE DEALINGS WITH PARENT. The Trustee in its individual or any
other capacity may become the owner or pledgee of Exchange Debentures and may
otherwise deal with the Parent or any of its Affiliates with the same rights it
would have if it were not Trustee.

        14. NO RECOURSE AGAINST OTHERS. No director, officer, employee,
incorporator or direct or indirect stockholder of Parent (other than Parent), as
such, shall have any liability for any obligation of Parent under the Indenture
or the Exchange Debentures or for any claim based on, in respect of, or by
reason of, any such obligation or the creation of any such obligation. Each
Holder by accepting an Exchange Debenture waives and releases such Persons from
all such liability, and such waiver and release is part of the consideration for
the issuance of the Exchange Debentures.

        15. MERGERS AND CERTAIN OTHER TRANSACTIONS. Parent will not permit the
Company, in a single transaction or a series of related transactions, (a)
consolidate or merge with or into (other than a merger with a Wholly-Owned
Restricted Subsidiary solely for the purpose of changing the Company's
jurisdiction of incorporation to another State of the United States), or sell,
lease, transfer, convey or otherwise dispose of or assign all or substantially
all of the assets of the Company or the Company and its Subsidiaries (taken as a
whole), or assign any of its obligations under the Notes and the Notes
Indenture, to any Person or (b) adopt a Plan of Liquidation unless, in either
case: (w) the Person formed by or surviving such consolidation or


                                      A-9












merger (if other than the Company) or to which such sale, lease, conveyance or
other disposition or assignment shall be made (or, in the case of a Plan of
Liquidation, any Person to which assets are transferred) (collectively, the
"SUCCESSOR"), is a corporation organized and existing under the laws of any
State of the United States of America or the District of Columbia, and the
Successor assumes by supplemental indenture in a form satisfactory to the
Trustee all of the obligations of the Company under the Notes and the Notes
Indenture; (x) immediately prior to and immediately after giving effect to such
transaction and the assumption of the obligations as set forth in clause (w)
above and the incurrence of any Indebtedness to be incurred in connection
therewith, no Default or Event of Default shall have occurred and be continuing;
and (y) immediately after and giving effect to such transaction and the
assumption of the obligations set forth in clause (w) above and the incurrence
of any Indebtedness to be incurred in connection therewith, and the use of any
net proceeds therefrom on a pro forma basis, (A) the Consolidated Net Worth of
Parent would be at least equal to the Consolidated Net Worth of Parent
immediately prior to such transaction and (B) the Company or the Successor, as
the case may be, could meet the Coverage Ratio Incurrence Condition. For
purposes of this covenant, any Indebtedness of the Successor which was not
Indebtedness of the Company immediately prior to the transaction shall be deemed
to have been incurred in connection with such transaction.

        16. GOVERNING LAW. This Exchange Debenture shall be governed by and
construed in accordance with the internal laws of the State of New York, without
regard to the conflict of laws provisions thereof.

        17. AUTHENTICATION. This Exchange Debenture shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent

        18. CUSIP/CINS NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Note Identification Procedures, the Company has caused
CUSIP and CINS numbers, as applicable, to be printed on the Exchange Debentures
and has directed the Trustee to use CUSIP and CINS numbers, as applicable, in
notices of redemption as a convenience to Holders. No representation is made as
to the accuracy of such numbers either as printed on the Exchange Debentures or
as contained in any notice of redemption and reliance may be placed only on the
other identification numbers printed on the Exchange Debentures.

        Parent will furnish to any Holder upon written request and without
charge a copy of the Indenture. Request may be made to: Eagle-Picher
Acquisition, Inc., 250 East Fifth Street, Cincinnati, Ohio, Attention:
Secretary.
