                                    THE NOTES

         SECTION 2.01.  Form and Dating. (a) General. The Notes and the
Trustee's certificate of authentication shall be substantially in the form of
Exhibit A to the Indenture, the terms of which are hereby incorporated into the
Indenture. The Notes may have notations, legends or endorsements required by
law, securities exchange rule, the Company's certificate of incorporation,
memorandum of association, articles of association, other organizational
documents, agreements to which the Company is subject, if any, or usage,
provided that any such notation, legend or endorsement is in a form acceptable

provisions contained in the Notes shall constitute, and are hereby expressly

nominee of the Depositary, duly executed by the Company and authenticated by the
Trustee as hereinafter provided. The aggregate principal amount of the Global
Notes may from time to time be increased or decreased by adjustments made on the

provided.

<PAGE>

         (c) Book-entry Provisions. This Section 2.01(c) shall apply only to a
Global Note deposited with or on behalf of the Depositary.

         The Company shall execute and the Trustee shall, in accordance with
this Section 2.01(c), authenticate and deliver initially one or more Global
Notes that shall be registered in the name of the Depositary for such Global
Note or Global Notes or the nominee of such Depositary and shall be delivered by
the Trustee to such Depositary or pursuant to such Depositary's instructions or
held by the Trustee as custodian for the Depositary.

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

         (d) Certificated Notes. Except as provided in this Section 2.01 or
Section 2.06 or 2.07, owners of beneficial interests in Global Notes will not be
entitled to receive physical delivery of certificated Notes.

         Section 2.02.  Execution and Authentication. One Officer of the Company
shall sign the Notes on behalf of the Company by manual or facsimile signature.
The Company's seal may be (but shall not be required to be) impressed, affixed,
imprinted or reproduced on the Notes and may be in facsimile form.

         If an Officer of the Company whose signature is on a Note no longer
holds that office at the time the Note is authenticated, the Note shall be valid
nevertheless.

         A Note shall not be entitled to any benefit under the Indenture or be
valid or obligatory for any purpose until authenticated by the manual signature
of an authorized signatory of the Trustee, which signature shall be conclusive
evidence that the Note has been authenticated under the Indenture.

         The Trustee shall authenticate (i) for original issue on the Initial
Issue Date, Series A Notes in the aggregate principal amount of $175,000,000,
(ii) Exchange Notes for original issue, pursuant to any Exchange Offer or
Private Exchange, for a like principal amount of Series A Notes and (iii) any
amount of additional Notes

                                       29

<PAGE>

specified by the Company, in each case, upon a written order of the Company
signed by one Officer of the Company. Such order shall specify (a) the amount of
the Notes to be authenticated and the date of original issue thereof, and (b)
whether the Notes are Series A Notes or Exchange Notes. The aggregate principal
amount of Notes of any series outstanding at any time may not exceed the
aggregate principal amount of Notes of such series authorized for issuance by
the Company pursuant to one or more written orders of the Company, except as
provided in Section 2.08 hereof. Subject to the foregoing, the aggregate
principal amount of Notes of any series that may be issued under the Indenture
shall not be limited.

         The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes. Unless limited by the terms of such appointment,
an authenticating agent may authenticate Notes whenever the Trustee may do so.
Each reference in the Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent has the same rights as an
Agent to deal with the Company, or an Affiliate of any of them.

         The Series A Notes and the Exchange Notes shall be considered
collectively to be a single class for all purposes of the Indenture, including,
without limitation, waivers, amendments, redemptions and offers to purchase.

         SECTION 2.03.  Registrar and Paying Agent. The Company shall maintain
an office or agency where Notes may be presented for registration of transfer or
exchange ("REGISTRAR") and an office or agency where Notes may be presented for
payment ("PAYING AGENT"). The Registrar shall keep a register of the Notes and
of their transfer and exchange. The Company may appoint one or more
co-registrars and one or more additional paying agents. The term "Registrar"
includes any co-registrar and the term "Paying Agent" includes any additional
paying agent.

         The Company shall enter into an appropriate agency agreement with any
Registrar or Paying Agent not a party to the Indenture. Such agreement shall
implement the provisions of the Indenture that relate to such Agent. The Company
shall notify the Trustee of the name and address of any Agent not a party to the
Indenture. The Company may change any Paying Agent or Registrar without notice
to any Holder. If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Company or any of
its Subsidiaries may act as Paying Agent or Registrar.

         The Company initially appoints the Trustee as Registrar and Paying
Agent.

         The Company initially appoints The Depository Trust Company ("DTC") to
act as Depositary with respect to each Global Note.

         SECTION 2.04.  Paying Agent to Hold Money in Trust. The Company shall
require each Paying Agent other than the Trustee to agree in writing that the
Paying Agent will hold in trust for the benefit of Holders or the Trustee all
money held by the Paying Agent for the payment of principal of or premium, if
any, or interest or Liquidated Damages, if any, on the Notes, whether such money
shall have been paid to it by the Company and will notify the Trustee of any
default by the Company in making any such payment. While any such default
continues, the Trustee may require a Paying Agent to pay all money held by it to
the Trustee and to account for any funds disbursed. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and to account
for any funds disbursed. Upon payment over to the Trustee and upon accounting
for any funds disbursed, the Paying Agent (if other than the Company or a
Subsidiary of the Company) shall have no further liability for the money. If the
Company or a Subsidiary of the Company acts as Paying Agent, it shall segregate
and hold in a separate trust fund for the benefit of the Holders all money held
by it 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 TIA Section
312(a). If the Trustee is not the Registrar, the Company shall furnish to the
Trustee at least seven 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 of the names and addresses
of Holders, and the Company shall otherwise comply with TIA Section 312(a).

         SECTION 2.06.  Transfer and Exchange.

         (a) Transfer and Exchange of Global Notes. (i) The transfer and
exchange of Global Notes or beneficial interests therein shall be effected
through the Depositary, in accordance with the Indenture (including applicable
restrictions on transfer set forth herein, if any) and the procedures of the
Depositary therefor. A transferor of a beneficial interest in a Global Note
(other than a transfer of a beneficial interest in a Global Note for a
beneficial interest in the same Global Note) shall deliver to the Registrar a
written order given in accordance with the Depositary's procedures containing
information regarding the participant account of the Depositary to be credited
with a beneficial interest in the Global Note. The Registrar shall, subject to
this Section 2.06, in accordance with such instructions, instruct the Depositary
to credit to the account of the Person specified in such instructions a
beneficial interest in the Global Note and to debit the account of the Person
making the transfer the beneficial interest in the Global Note being
transferred. The Trustee shall refuse to register any requested transfer or
exchange that does not comply with the preceding sentence.

                                       31

<PAGE>

                  (ii)  Notwithstanding any other provisions of the Indenture
         (other than the provisions set forth in Section 2.07), a Global Note
         may not be transferred as a whole except by the Depositary to a nominee
         of the Depositary or by a nominee of the Depositary to the Depositary
         or another nominee of the Depositary or by the Depositary or any such
         nominee to a successor Depositary or a nominee of such successor
         Depositary.

                  (iii) If a Global Note is exchanged for Notes in definitive
         registered form pursuant to this Section 2.06 or Section 2.07, prior to
         the consummation of an Exchange Offer or prior to or in a transfer made
         pursuant to an effective Shelf Registration Statement with respect to
         such Notes, such Notes may be exchanged only in accordance with such
         procedures as are substantially consistent with the provisions of this
         Section 2.06 (including the certification and other requirements set
         forth on the reverse of the Series A Notes intended to ensure that such
         transfers comply with Rule 144A or Regulation S, as the case may be, or
         are otherwise in compliance with the requirements of the Securities
         Act) and such other procedures as may from time to time be adopted by
         the Company.

         (b) Legend. Except as permitted by the following paragraphs (c), (d),
(e) and (f), each Note certificate evidencing the Global Notes (and all Notes
issued in exchange therefor or in substitution thereof) shall bear a legend in

         and/or an Opinion of Counsel and such other certifications and evidence
         as the Company may reasonably require in order to determine that the
         proposed transfer or exchange is being made in compliance with the
         Securities Act and any applicable securities laws of any state of the
         United States; provided that if the requested transfer or exchange is
         made by the Holder of a certificated Note that does not bear the
         Restricted Notes Legend, then no certification is required. In the
         event that (i) the requested transfer or exchange takes place after the
         Restricted Period and a duly completed Regulation S Certificate is
         delivered to the Trustee or (ii) a certificated Note that does not bear
         the Restricted Notes Legend is surrendered for

                                       34

<PAGE>

         transfer or exchange, upon transfer or exchange the Trustee will
         deliver a certificated Note that does not bear the Restricted Notes
         Legend.

                  (iv)  The Person requesting the transfer or exchange must
         deliver or cause to be delivered to the Trustee a duly completed Rule
         144A Certificate.

                  (v)   Notwithstanding anything to the contrary contained
         herein, no such exchange is permitted if the requested exchange is made
         during the Restricted Period. If the requested transfer involves a
         beneficial interest in a Regulation S Global Note during the Restricted
         Period, the Person requesting the transfer must deliver or cause to be
         delivered to the Trustee a duly completed Rule 144A Certificate and/or
         an Opinion of Counsel and such other certifications and evidence as the
         Company may reasonably require in order to determine that the proposed
         transfer is being made in compliance with the Securities Act and any
         applicable securities laws of any state of the United States. If the
         requested transfer or exchange involves a beneficial interest in a
         Regulation S Global Note after the Restricted Period, no certification
         is required and the Trustee will deliver a certificated Note that does
         not bear the Restricted Notes Legend.

         (d) Rule 144A Transfers. Upon any sale or transfer of a Transfer
Restricted Note (including any Transfer Restricted Note represented by a Rule
144A Global Note) pursuant to Rule 144 under the Securities Act, the Registrar
shall permit the Holder thereof to exchange such Transfer Restricted Note for a
Note (or, in the case of any Transfer Restricted Note that is represented by a
Rule 144A Global Note, an interest in a Global Note) that does not bear the
legend set forth above and rescind any restriction on the transfer of such
Transfer Restricted Note, if the Holder certifies in writing to the Registrar
that its request for such exchange was made in reliance on Rule 144 (such
certification to be in the form set forth on the reverse of the Note).

         (e) Transfers Pursuant to an Effective Shelf Registration Statement.
After a transfer of any Series A Notes or Private Exchange Notes during the
period of the effectiveness of and pursuant to a Shelf Registration Statement
with respect to such Series A Notes or Private Exchange Notes, as the case may
be, all requirements pertaining to legends on such Note or such Private Exchange
Note will cease to apply.

         (f) Transfers Pursuant to a Registered Exchange Offer. Upon the
consummation of a Registered Exchange Offer with respect to the Series A Notes
pursuant to which Holders of such Series A Notes are offered Exchange Notes in
exchange for their Series A Notes, Exchange Notes in certificated or global form
(depending on whether certificated Notes or interests in Global Notes are

                                       35

<PAGE>

exchanged), in each case not bearing the Restricted Notes Legend, will be
available to Holders that exchange such Series A Notes in such Exchange Offer.

         (g) Private Exchanges. Upon the consummation of a Private Exchange with
respect to the Series A Notes pursuant to which Holders of such Series A Notes
are offered Private Exchange Notes in exchange for their Series A Notes, Private
Exchange Notes in certificated or global form (depending on whether certificated
Notes or interests in Global Notes are exchanged) with the Restricted Notes
Legend will be available to Holders that exchange such Series A Notes in such
Private Exchange.

         (h) Cancellation or Adjustment of Global Note. At such time as all
beneficial interests in a Global Note have either been exchanged for
certificated Notes, redeemed, repurchased or canceled, such Global Note shall be
returned to the Depositary for cancellation or retained and canceled by the
Trustee. At any time prior to such cancellation, if any beneficial interest in a
Global Note is exchanged for certificated Notes, redeemed, repurchased or
canceled, the principal amount of Notes represented by such Global Note shall be
reduced and an adjustment shall be made on the books and records of the Trustee
(if it is then the Notes Custodian for such Global Note) with respect to such
Global Note, by the Trustee or the Notes Custodian, to reflect such reduction.

         (i) Obligations with Respect to Transfers and Exchanges of Notes.

                  (i)   To permit registrations of transfers and exchanges, the
         Company shall execute and the Trustee shall authenticate certificated
         Notes and Global Notes at the Registrar's or co-Registrar's request. No
         service charge shall be made for any registration of transfer or
         exchange, but the Company may require payment of a sum sufficient to
         cover any transfer tax, assessments, or similar governmental charge
         payable in connection therewith (other than any such transfer taxes,
         assessments or similar governmental charge payable upon exchange or
         transfer pursuant to Sections 5.11, 8.05 and 9.06).

                  (ii)  The Registrar or co-registrar shall not be required to
         register the transfer of or exchange of (a) any certificated Note
         selected for redemption in whole or in part pursuant to Article IX,
         except the unredeemed portion of any certificated Note being redeemed
         in part, or (b) any Note for a period beginning 15 Business Days before
         the mailing of a notice of an offer to repurchase or redeem Notes or 15
         Business Days before an interest payment date.

                  (iii) Prior to the due presentation for registration of
         transfer of any Note, the Company, the Trustee, the Paying Agent, the
         Registrar or any co-Registrar may deem and treat the Person in whose
         name a Note is

                                       36

<PAGE>

         registered as the absolute owner of such Note for the purpose of
         receiving payment of principal of, premium, if any, and interest and
         Liquidated Damages, if any, on such Note and for all other purposes
         whatsoever, whether or not such Note is overdue, and none of the
         Company, the Trustee, the Paying Agent, the Registrar or any
         co-registrar shall be affected by notice to the contrary.

                  (iv)  All Notes issued upon any transfer or exchange pursuant
         to the terms of the Indenture shall evidence the same debt and shall be
         entitled to the same benefits under the Indenture as the Notes
         surrendered upon such transfer or exchange.

         (j) No Obligation of the Trustee.

                  (i)   The Trustee shall have no responsibility or obligation
         to any beneficial owner of a Global Note, any Agent Member or other
         Person with respect to the accuracy of the records of the Depositary or
         its nominee or of any participant or member thereof, with respect to
         any ownership interest in the Notes or with respect to the delivery to
         any participant, member, beneficial owner or other Person (other than
         the Depositary) of any notice (including any notice of redemption) or
         the payment of any amount, under or with respect to such Notes. All
         notices and communications to be given to the Holders and all payments
         to be made to Holders under the Notes shall be given or made only to or
         upon the order of the registered Holders (which shall be the Depositary
         or its nominee in the case of a Global Note). The rights of beneficial
         owners in any Global Note shall be exercised only through the
         Depositary subject to the applicable rules and procedures of the
         Depositary. The Trustee may rely conclusively and shall be fully
         protected in relying upon information furnished by the Depositary with
         respect to its members, participants and any beneficial owners.

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

         SECTION 2.07.  Certificated Notes.

         (a) A Global Note deposited with the Depositary or with the Trustee as
custodian for the Depositary pursuant to Section 2.01 shall be transferred to
the beneficial owners thereof in the form of certificated Notes in an aggregate
principal amount equal to the principal amount of such Global Note, in exchange
for such Global Note, only if such transfer complies with Section 2.06 and (i)
the Depositary notifies the Company that it is unwilling or unable to continue
as Depositary for such Global Note or if at any time such Depositary ceases to
be a "clearing agency" registered under the Exchange Act and a successor
depositary is not appointed by the Company within 90 days of such notice, (ii)
the Company, in its sole discretion, notifies the Trustee in writing that it
elects to cause the issuance of certificated Notes under the Indenture; or (iii)
there has occurred and is continuing a Default or Event of Default with respect
to the Notes.

         (b) Any Global Note that is transferred to the beneficial owners
thereof pursuant to this Section shall be surrendered by the Depositary to the
Trustee at its office located in the Borough of Manhattan, The City of New York,
to be so transferred, in whole or from time to time in part, without charge, and
the Trustee shall authenticate and deliver, upon such transfer of each portion
of such Global Note, an equal aggregate principal amount of certificated Notes
of authorized denominations. Any portion of a Global Note transferred pursuant
to this Section shall be executed, authenticated and delivered only in
denominations of $1,000 and any integral multiple thereof and registered in such
names as the Depositary shall direct. Any certificated Note delivered in
exchange for an interest in the Global Note shall, except as otherwise provided
by Section 2.06(c), bear the restricted securities legend set forth in Section
2.06(b).

         (c) Subject to the provisions of Section 2.06(b), the registered Holder
of a Global Note 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 the Indenture or the Notes.

         (d) If any of the events specified in Section 2.07(a) occurs, the
Company shall promptly make available to the Trustee a reasonable supply of
certificated Notes in definitive, fully registered form without interest
coupons.

         (e) If a certificated Note issued pursuant to this Section 2.07 is
exchanged for another certificated Note prior to the consummation of an Exchange
Offer or prior to or in a transfer made pursuant to an effective Shelf
Registration Statement with respect to such Notes, such Notes may be exchanged
only in accordance with such procedures as are substantially consistent with the
provisions of (i) Section 2.06(a)(iii) (including the certification and other
requirements set forth on the reverse of the Series A Notes intended to ensure
that such transfers comply with Rule 144A or Regulation S, as the case may be,
or are otherwise in

                                       38

<PAGE>

compliance with the requirements of the Securities Act) and such other
procedures as may from time to time be adopted by the Company and (ii) Section
2.06(b).

         SECTION 2.08.  Replacement Notes.

         If any mutilated Note is surrendered to the Trustee, or the Company and
the Trustee receive evidence to their satisfaction of the destruction, loss or
theft of any Note, the Company shall issue and the Trustee shall authenticate a
replacement Note, but only if the Trustee's requirements are met. If required by
the Trustee or the Company, such Holder must furnish an indemnity bond that is
sufficient in the judgment of the Trustee and the Company to protect the
Company, the Trustee, any Agent or any authenticating agent from any loss which
any of them may suffer if a Note is replaced. The Company and the Trustee may
charge for their expenses in replacing a Note. If, after the delivery of such
replacement Note, a bona fide purchaser of the original Note in lieu of which
such replacement Note was issued presents for payment or registration such
original Note, the Trustee shall be entitled to recover such replacement Note
from the Person to whom it was delivered or any Person taking therefrom, except
a bona fide purchaser, and shall be entitled to recover upon the security or
indemnity provided therefor to the extent of any loss, damage, cost or expense
incurred by the Trustee or the Company in connection therewith.

         Every replacement Note is an additional obligation of the Company.

         SECTION 2.09.  Outstanding Notes.

         The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the
Trustee hereunder and those described in this Section 2.09 as not outstanding;
provided, however, that in determining whether the holders of the requisite
principal amount of outstanding Notes are present at a meeting of holders of
Notes for quorum purposes or have consented to or voted in favor of any request,
demand, authorization, direction, notice, consent, waiver, amendment or
modification hereunder, Notes held for the account of the Company, any of its
Subsidiaries or any of their respective Affiliates shall be disregarded and
deemed not to be outstanding, except that in determining whether the Trustee
shall be protected in making such a determination or relying upon any such
quorum, consent or vote, only Notes which a Responsible Officer of the Trustee
actually knows to be so owned shall be so disregarded.

         If a Note is replaced pursuant to Section 2.08 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

                                       39

<PAGE>

         If the principal amount of any Note is considered paid under Section
3.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

         A Note does not cease to be outstanding because the Company or any of
its Affiliates holds the Note.

         SECTION 2.10.  Treasury Notes.

         In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company or any of its Affiliates shall be disregarded, except that for the
purpose of determining whether the Trustee shall be protected in relying on any
such direction, waiver or consent, only Notes which a Responsible Officer of the
Trustee actually knows are so owned shall be so disregarded.

         SECTION 2.11.  Temporary Notes.

         Until definitive Notes are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Notes. Temporary Notes shall be
substantially in the form of definitive Notes, but may have variations that the
Company considers appropriate for temporary Notes. Without unreasonable delay,
the Company shall prepare and the Trustee shall authenticate definitive Notes in
exchange for temporary Notes. Until so exchanged, the temporary Notes shall in
all respects be entitled to the same benefits under the Indenture as definitive
Notes.

         SECTION 2.12.  Cancellation.

         The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee shall cancel all Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation. All canceled Notes held by the
Trustee shall be disposed of in accordance with the usual disposal procedures of
the Trustee. The Company may not issue new Notes to replace Notes that have been
paid or that have been delivered to the Trustee for cancellation.

         SECTION 2.13.  Defaulted Interest.

         If the Company defaults in a payment of interest on the Notes, it shall
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest on the defaulted interest, in each case at the rate provided in the
Notes and in Section 3.01 hereof. The Company may pay the defaulted interest to
the Persons who are Holders on a subsequent special record date. At least 15
days before any special record date, the Company (or the Trustee, in the name of
and at the expense of the

                                       40

<PAGE>

Company) shall mail to Holders a notice that states the special record date, the
related payment date and the amount of such interest to be paid.

         SECTION 2.14.  Persons Deemed Owners.

         The Company, the Trustee, any Agent and any authenticating agent may
treat the Person in whose name any Note is registered as the owner of such Note
for the purpose of receiving payments of principal of or premium, if any, or
interest on such Note and for all other purposes. None of the Company, the
Trustee, any Agent or any authenticating agent shall be affected by any notice
to the contrary.

         SECTION 2.15.  CUSIP Numbers. The Company in issuing the Notes may use
"CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use
"CUSIP" numbers in notices of redemption as a convenience to Holders; provided
that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Notes or as contained in
any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Notes, and any such redemption shall not
be affected by any defect in or omission of such numbers. The Company shall
promptly notify the Trustee of any change in the "CUSIP" numbers.

                                    ARTICLE 3

                                    COVENANTS

         SECTION 3.01.  Payment of Notes. The Company shall pay the principal of
and premium, if any, Liquidated Damages, if any, and interest on the Notes on
the dates and in the manner provided in the Notes and in the Indenture.
Principal, premium, if any, Liquidated Damages, if any, and interest shall be
considered paid on the date due if the Paying Agent, other than the Company or a
Subsidiary of the Company, holds by 11:00 a.m., Eastern time, on that date money
deposited by the Company designated for and sufficient to pay all principal,
premium, if any, Liquidated Damages, if any, and interest then due.

         To the extent lawful, the Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal, premium, if any, Liquidated Damages, if any, and interest payments
(without regard to any applicable grace period) at a rate equal to the then
applicable interest rate on the Notes.

         SECTION 3.02.  Maintenance of Office or Agency. The Company shall
maintain, in the Borough of Manhattan, The City of New York, an office or agency
(which may be an office of the Trustee, the Registrar or the Paying Agent) where
Notes may be presented for registration of transfer or exchange, where

                                       41

<PAGE>

Notes may be presented for payment and where notices and demands to or upon the
Company in respect of the Notes and the Indenture may be served. Unless
otherwise designated by the Company by written notice to the Trustee, such
office or agency shall be the principal office of the Trustee in the Borough of
Manhattan, The City of New York, which, on the date hereof, is located at the
address set forth in Section 11.02 hereof. The Company shall give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee.

         The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, The City of New York for such purposes. The Company shall 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. The Company hereby
designates the Corporate Trust Office of the Trustee as one such office or
agency of the Company in accordance with Section 2.03 hereof.

         SECTION 3.03.  Commission Reports; Financial Statements. (a) Whether or
not required by the Commission, so long as any Notes are outstanding, the
Company will furnish to the Trustee, within 15 days after the time periods
specified in the Commission's rules and regulations:

                  (i)   all quarterly and annual financial information that
         would be required to be contained in a filing with the Commission on
         Forms 10-Q and 10-K if the Company were required to file such reports,
         including a "Management's Discussion and Analysis of Financial
         Condition and Results of Operations" (or, if applicable to the Company
         for such filings at such time, or if such filings were required at such
         time, a "Management's Narrative and Analysis of Results of
         Operations"), and, with respect to the annual information only, a
         report on the annual financial statements by the Company's certified
         independent accountants; and

                  (ii)  all current reports that would be required to be filed
         with the Commission on Form 8-K if the Company were required to file
         such reports.

         (b) If the Company has designated any of its Subsidiaries as
Unrestricted Subsidiaries, then the quarterly and annual financial information
required by paragraph (a) will include a reasonably detailed presentation,
either on the face of

                                       42

<PAGE>

the financial statements or in the footnotes thereto, and in Management's
Discussion and Analysis of Financial Condition and Results of Operations (or, as
applicable, in Management's Narrative and Analysis of Results of Operations), of
the financial condition and results of operations of the Company and its
Restricted Subsidiaries separate from the financial condition and results of
operations of the Unrestricted Subsidiaries of the Company.

         (c) In addition, following the consummation of the Exchange Offer,
whether or not required by the Commission, the Company will file a copy of all
of the information and reports referred to in clauses (1) and (2) above with the
Commission for public availability within the time periods specified in the
Commission's rules and regulations (unless the Commission will not accept such a
filing) and make such information available to securities analysts and
prospective investors upon request. In addition, the Company and the Guarantors
will, for so long as any Notes remain outstanding, furnish to the Holders and to
securities analysts and prospective investors, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act.

         (d) The Company shall provide the Trustee with a sufficient number of
copies of all reports and other documents and information that the Trustee may
be required to deliver to Holders under this Section.

         (e) Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officer's Certificates).

         SECTION 3.04.  Compliance Certificate. (a) The Company shall deliver to
the Trustee, on or prior to the last day of the fifth month after the end of
each fiscal year of the Company, a statement signed by two Officers of the
Company (one of whom shall be the principal financial, principal accounting or
principal executive officer of the Company), which statement need not constitute
an Officers' Certificate, complying with TIA Section 314(a)(4) and stating that
in the course of performance by the signing Officers of the Company of their
duties as such Officers, they would normally obtain knowledge of the keeping,
observing, performing and fulfilling by the Company, of its obligations under
the Indenture, and further stating, as to each such Officer signing such
statement, that to his knowledge, the Company has kept, observed, performed and
fulfilled each and every covenant contained in the Indenture and is not in
default in the performance or observance of any of the terms, provisions and
conditions hereof (or, if a Default or Event of Default shall have occurred,
describing all such Defaults or Events of Default of which such Officer may have
knowledge and what action the Company is taking or proposes to take with respect
thereto).

<PAGE>

         SECTION 3.05.  Limitation on Restricted Payments. (a) The Company will
not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly:

                  (i) declare or pay any dividend or make any other payment or
         distribution on account of the Company's or any of its Restricted
         Subsidiaries' Equity Interests (including, without limitation, any
         payment in connection with any merger or consolidation involving the
         Company or any of its Restricted Subsidiaries) or to the direct or
         indirect holders of the Company's or any of its Restricted
         Subsidiaries' Equity Interests in their capacity as such (other than
         dividends or distributions payable in Equity Interests (other than
         Disqualified Stock) of the Company or to the Company or a Restricted
         Subsidiary of the Company);

                  (ii) purchase, redeem or otherwise acquire or retire for value
         (including, without limitation, in connection with any merger or
         consolidation involving the Company) any Equity Interests of the
         Company or any direct or indirect parent of the Company;

                  (iii) make any payment on or with respect to, or purchase,
         redeem, defease or otherwise acquire or retire for value any
         Indebtedness that is subordinated to the Notes or the Subsidiary
         Guarantees, except a payment of interest or principal at the Stated

Payment, no Default or Event of Default has occurred and is continuing or would
occur as a consequence of such Restricted Payment; and

                  (1) if the Fixed Charge Coverage Ratio for the Company's four
         most recent fiscal quarters for which internal financial statements are

         together with the aggregate amount of all other Restricted Payments
         made by the Company and its Restricted Subsidiaries after the end of
         the fiscal year of the Company then most recently ended for which
         internal financial statements are available, is less than the sum,
         without duplication, of:

         distributions on the Company's common stock and loans and advances to
         Williams and its Subsidiaries), is less than the sum, without

                  clause (2)(A) during the period ending on the last day
                  immediately preceding the date on which such internal
                  financial statements are available and beginning on the date

                  minus the aggregate amount of Restricted Payments previously
                  made in reliance on such Incremental Funds pursuant to this
                  clause (2) or clause (1) above.

         (b) Notwithstanding the foregoing, the preceding provisions will not
prohibit:

                  (i) the payment of any dividend within 60 days after the date
         of declaration of the dividend, if at the date of declaration the
         dividend payment would have complied with the provisions of the
         Indenture;

                  (ii) so long as no Default or Event of Default has occurred
         and is continuing or would be caused thereby, the redemption,
         repurchase, retirement, defeasance or other acquisition of any
         subordinated Indebtedness of the Company or any Guarantor or of any

         or (b) sale (other than to a Subsidiary of the Company) of, Equity
         Interests of the Company (other than Disqualified Stock); provided that
         the amount of any such net cash proceeds that are utilized for any such
         redemption, repurchase, retirement, defeasance or other acquisition
         will be excluded from clause (1) (B) of the preceding paragraph;

                  (iii) so long as no Default or Event of Default has occurred
         and is continuing or would be caused thereby, the defeasance,
         redemption, repurchase or other acquisition of subordinated
         Indebtedness of the Company or any Guarantor with the net cash proceeds

         amounts expended by Williams for the repurchase, redemption or

         acquisition or retirement for value of any Equity Interests of Williams
         held by any member of the Company's (or any of its Restricted
         Subsidiaries') management pursuant to any management equity
         subscription agreement, stock option agreement or similar agreement;
         provided that the aggregate price paid for all such repurchased,
         redeemed, acquired or retired Equity Interests may not exceed $2.0
         million in any twelve-month period and provided further that if the
         amount so paid in any calendar year is less than $2.0 million, such
         shortfall may be used to so repurchase, redeem, acquire or retire
         Equity Interests in either of the next two calendar years in addition
         to the $2.0 million that may otherwise be paid in each such calendar
         year; and

                  (vi) prior to the Credit Agreement Refinancing Date, the
         ability (i) to pay, directly or indirectly, dividends or make any other
         distributions in respect of its capital stock or pay any Debt or other
         obligation owed to Williams or any of its Subsidiaries, or (ii) to make
         loans or advances to Williams or any of its Subsidiaries.

         (c) In computing the amount of Restricted Payments previously made for
purposes of the immediately preceding paragraph, Restricted Payments made under
clause (i) (but only if the declaration or such dividend or other distribution
has not been counted in a prior period), clause (iv) (but only to the extent of
amounts paid to Holders other than the Company or any of its Restricted
Subsidiaries), clause (v) and clause (vi) of this paragraph shall be included,
and Restricted Payments made under clauses (ii), (iii) and (iv) (except as noted
above) shall be excluded.

         (d) The amount of all Restricted Payments (other than cash) will be the
fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The fair market value of any assets or securities that are required to be valued
by this covenant will be determined, in the case of amounts under $5.0 million,
by an Officer of the Company and, in the case of amounts over $5.0 million, by
the Board of Directors of the Company.

         SECTION 3.06.  Limitation on Incurrence of Indebtedness and Issuance of
Preferred Stock.

         (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "INCUR") any Indebtedness (including Acquired
Debt), and the Company will not issue any Disqualified Stock and will not permit
any of its Restricted Subsidiaries to issue any shares of preferred stock;
provided, however,

                                       47

<PAGE>

that the Company and any Guarantor may incur Indebtedness (including Acquired
Debt) or the Company may issue Disqualified Stock, if the Fixed Charge Coverage
Ratio for the Company's most recently ended four full fiscal quarters for which
internal financial statements are available immediately preceding the date on
which such additional Indebtedness is incurred or such Disqualified Stock is
issued would have been at least 2.0 to 1, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness had been incurred or Disqualified Stock had been issued,
as the case may be, at the beginning of such four-quarter period.

         (b) Paragraph (a) of this covenant will not prohibit the incurrence of
any of the following items of Indebtedness (collectively, "PERMITTED DEBT"):

                  (i) the incurrence by the Company and any Guarantor of
         additional Indebtedness and letters of credit under any Credit
         Facilities to which the Company is a party in an aggregate principal
         amount at any one time outstanding under this clause (i) (with letters
         of credit being deemed to have a principal amount equal to the undrawn
         face amount thereof) not to exceed $400 million;

                  (ii) the incurrence by the Company and its Restricted
         Subsidiaries of the Existing Indebtedness;

                  (iii) the incurrence by the Company of Indebtedness
         represented by the Notes issued and sold in this offering and any
         Subsidiary Guarantees issued pursuant to the Indenture;

                  (iv) the incurrence by the Company and any of its Restricted
         Subsidiaries of Indebtedness represented by Capital Lease Obligations,
         mortgage financings or purchase money obligations, in each case,
         incurred for the purpose of financing all or any part of the purchase
         price or cost of construction or improvement of property, plant or
         equipment used in the business of the Company or such Restricted
         Subsidiary, in an aggregate principal amount not to exceed $5 million
         at any time outstanding;

                  (v) the incurrence by the Company or any of its Restricted
         Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or
         the net proceeds of which are used to refund, refinance or replace
         Indebtedness (other than intercompany Indebtedness) that was permitted
         by the Indenture to be incurred under paragraph (a) of this Section
         3.06 or clauses (ii), (iii), (iv) or (v) of this paragraph (b) of this
         Section 3.06;

                  (vi) the incurrence by the Company or any of its Restricted
         Subsidiaries of intercompany Indebtedness between or among the Company
         and any of its Restricted Subsidiaries; provided, however, that:

                                       48

<PAGE>

                      (A) if the Company or any Guarantor is the obligor on such
                  Indebtedness, such Indebtedness must be expressly subordinated
                  to the prior payment in full in cash of all Obligations with
                  respect to the Notes, in the case of the Company, or the
                  Subsidiary Guarantee, in the case of a Guarantor; and

                      (B) (i) any subsequent issuance or transfer of Equity
                  Interests that results in any such Indebtedness being held by
                  a Person other than the Company or a Restricted Subsidiary of
                  the Company and (ii) any sale or other transfer of any such
                  Indebtedness to a Person that is not either the Company or a
                  Restricted Subsidiary of the Company, will be deemed, in each
                  case, to constitute an incurrence of such Indebtedness by the
                  Company or such Restricted Subsidiary, as the case may be,
                  that was not permitted by this clause (vi);

                  (vii) the incurrence by the Company or any of its Subsidiaries
         of Hedging Obligations;

                  (viii) the guarantee by any of the Guarantors of Indebtedness
         of the Company or any Guarantor of the Company that was permitted to be
         incurred by another provision of this Section 3.06;

                  (ix) Indebtedness in respect of bankers acceptances, letters
         of credit and performance or surety bonds issued for the account of the
         Company or any of its Restricted Subsidiaries in the ordinary course of
         business in amounts and for the purposes customary in the Company's
         industry, in each case only to the extent that such incurrence does not
         result in the incurrence of any obligation to repay any borrowed money;
         and

                  (x) the incurrence by the Company or any of its Restricted
         Subsidiaries of additional Indebtedness in an aggregate principal
         amount (or accreted value, as applicable) at any time outstanding,
         including all Permitted Refinancing Indebtedness incurred to refund,
         refinance or replace any Indebtedness incurred pursuant to this clause
         (x), not to exceed $25 million.

         (c) If any Non-Recourse Debt of an Unrestricted Subsidiary shall at any
time cease to constitute Non-Recourse Debt or such Unrestricted Subsidiary shall
be redesignated a Restricted Subsidiary, such event will be deemed to constitute
an incurrence of Indebtedness by a Restricted Subsidiary.

         (d) For purposes of determining compliance with this Section:

                                       49

<PAGE>

                  (i) in the event that an item of proposed Indebtedness
         (including Acquired Debt) meets the criteria of more than one of the
         categories of Permitted Debt described in clauses (i) through (x) of
         paragraph (b) of this Section 3.06, or is entitled to be incurred
         pursuant to paragraph (a) of this Section, the Company will be
         permitted to classify (or later classify or reclassify in whole or in
         part in its sole discretion) such item of Indebtedness in any manner
         that complies with this Section;

                  (ii) the accrual of interest, the accretion or amortization of
         original issue discount, the payment of interest on any Indebtedness in
         the form of additional Indebtedness with the same terms, and the
         payment of dividends on Disqualified Stock in the form of additional
         shares of the same class of Disqualified Stock will not be deemed to be
         an incurrence of Indebtedness or an issuance of Disqualified Stock for
         purposes of this Section, provided, in each such case, that the amount
         thereof is included in the computation of Fixed Charges of the Company
         as accrued; and

                  (iii) for the purposes of determining compliance with any
         dollar- denominated restriction on the incurrence of Indebtedness
         denominated in a foreign currency, the dollar-equivalent principal
         amount of such Indebtedness incurred pursuant thereto shall be
         calculated based on the relevant currency exchange rate in effect on
         the date that such Indebtedness was incurred.

         SECTION 3.07.  Limitation on Liens. The Company will not, and will not
permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise
cause or suffer to exist or become effective any Lien of any kind securing
Indebtedness, Attributable Debt or trade payables (other than Permitted Liens)
upon any of their property or assets, now owned or hereafter acquired, unless
all payments due under the Indenture and the Notes are secured on an equal and
ratable basis with the obligations so secured until such time as such
obligations are no longer secured by a Lien or, in the case of any obligation so
secured that is expressly subordinated to the Notes or any Subsidiary Guarantee,
as applicable, by a Lien prior to any Liens securing any and all obligations
thereby secured for so long as any such obligations shall be so secured.

         SECTION 3.08.  Limitation on Dividend and Other Payment Restrictions
Affecting Restricted Subsidiaries. (a) The Company will not, and will not permit
any of its Restricted Subsidiaries to, directly or indirectly, create or permit
to exist or become effective any consensual encumbrance or restriction on the
ability of any Restricted Subsidiary to:

                  (i) pay dividends or make any other distributions on its
         Capital Stock to the Company or any of its Subsidiaries, or with
         respect to any

                                       50

<PAGE>

         other interest or participation in, or measured by, its profits, or pay
         any indebtedness owed to the Company or any of its Restricted
         Subsidiaries;

                  (ii) make loans or advances to the Company or any of its
         Restricted Subsidiaries; or

                  (iii) transfer any of its properties or assets to the Company
         or any of its Restricted Subsidiaries.

         (b) Notwithstanding the foregoing, the preceding restrictions will not
apply to encumbrances or restrictions existing under or by reason of:

                  (i) agreements governing Existing Indebtedness and the Credit
         Agreement as in effect on the date of the Indenture and any amendments,
         modifications, restatements, renewals, increases, supplements,
         refundings, replacements or refinancings of those agreements, provided
         that the amendments, modifications, restatements, renewals, increases,
         supplements, refundings, replacement or refinancings are no more
         restrictive in any material respect, taken as a whole, with respect to
         such dividend and other payment restrictions than those contained in
         the respective agreements on the date of the Indenture, as determined
         by the Board of Directors of the Company in their reasonable and good
         faith judgment;

                  (ii) the Indenture, the Notes and the Subsidiary Guarantees;

                  (iii) applicable law;

                  (iv) any instrument governing Indebtedness or Capital Stock of
         a Person acquired by the Company or any of its Restricted Subsidiaries
         as in effect at the time of such acquisition (except to the extent such
         Indebtedness or Capital Stock was incurred in connection with or in
         contemplation of such acquisition), which encumbrance or restriction is
         not applicable to any Person, or the properties or assets of any
         Person, other than the Person, or the property or assets of the Person,
         so acquired, provided that, in the case of Indebtedness, such
         Indebtedness was permitted by the terms of the Indenture to be
         incurred;

                  (v) customary non-assignment provisions in leases entered into
         in the ordinary course of business and consistent with past practices;

                  (vi) Capital Lease Obligations, mortgage financings or
         purchase money obligations for property acquired in the ordinary course
         of business that impose restrictions on that property of the nature
         described in clause (iii) of paragraph (a);

                                       51

<PAGE>

                  (vii) any agreement for the sale or other disposition of a
         Restricted Subsidiary that restricts distributions by that Restricted
         Subsidiary pending its sale or other disposition;

                  (viii) Permitted Refinancing Indebtedness, provided that the
         restrictions contained in the agreements governing such Permitted
         Refinancing Indebtedness are no more restrictive in any material
         respect, taken as a whole, than those contained in the agreements
         governing the Indebtedness being refinanced;

                  (ix) Liens securing Indebtedness otherwise permitted to be
         incurred under the provisions of Section 3.07 that limit the right of
         the debtor to dispose of the assets subject to such Liens;

                  (x) provisions with respect to the disposition or distribution
         of assets or property in joint venture agreements, assets sale
         agreements, stock sale agreements and other similar agreements,
         provided that such restrictions apply only to the assets or property
         subject to such joint venture or similar agreement or to the assets or
         property being sold, as the case may be; and

                  (xi) restrictions on cash or other deposits or net worth
         imposed by customers under contracts entered into in the ordinary
         course of business.

         SECTION 3.09.  Additional Interest. If, at any time and from time to
time after the date of the Indenture but prior to the earlier of (1) the Credit
Agreement Refinancing Date and (2) the Investment Grade Date, the Fixed Charge
Coverage Ratio for the Company's four most recent fiscal quarters for which
internal financial statements are available is less than 1.75 to 1.0, then, from
(A) the date of any such determination until (B) the earliest of (1) the next
date (if any) on which the Fixed Charge Coverage Ratio for the Company's four
most recent fiscal quarters then most recently ended for which internal
financial statements are available is equal to or greater than 1.75 to 1.0, (2)
the Credit Agreement Refinancing Date and (3) the Investment Grade Date, the
interest rate otherwise applicable to the Notes will be increased by a rate of
1.00% per annum. The Company shall give prompt written notice to the Trustee of
any such increase or decrease in the interest rate applicable to the Notes
pursuant to this Section 3.09.

         SECTION 3.10.  Guaranties by Restricted Subsidiaries. If the Company or
any of its Restricted Subsidiaries acquires or creates another Domestic
Restricted Subsidiary after the date of the Indenture, then that newly acquired
or created Domestic Restricted Subsidiary will become a Guarantor and execute a
Supplemental Indenture in the form of Exhibit B and deliver to the Trustee an
Opinion of Counsel to the effect that the Supplemental Indenture has been duly

                                       52

<PAGE>

authorized, executed and delivered by such Domestic Restricted Subsidiary and
constitutes a valid and binding obligation of such Domestic Restricted
Subsidiary, enforceable against such Domestic Restricted Subsidiary in
accordance with its terms (subject to customary exceptions), all within 10
Business Days of the date on which it was acquired or created; provided,
however, that the foregoing shall not apply to Subsidiaries that have properly
been designated as Unrestricted Subsidiaries in accordance with the Indenture
for so long as they continue to constitute Unrestricted Subsidiaries.

         SECTION 3.11.  Repurchase of Notes upon a Change of Control. (a)
Subject to paragraph (b) of this Section, not later than 30 days following a
Change of Control, the Company will make a Change of Control Offer to purchase
all outstanding Notes at a purchase price (the "CHANGE OF CONTROL PAYMENT")
equal to 101% of the principal amount plus accrued and unpaid interest and
Liquidated Damages, if any, to the date of purchase; provided that the Company
will not be required to make a Change of Control Offer upon a Change of Control
if a third party makes the Change of Control Offer in the manner, at the times
and otherwise in compliance with the requirements set forth in the Indenture
applicable to a Change of Control Offer made by the Company and purchases all
Notes properly tendered and not withdrawn under the Change of Control Offer.

         (b) Prior to complying with any of the provisions of this Section, but
in any event within 30 days following a Change of Control, if the Company or any
of its Williams Group Affiliates is subject to any agreement evidencing
Indebtedness (or commitments to extend Indebtedness) that prohibits prepayment
or repurchase of the Notes pursuant to a Change of Control Offer, the Company
will either repay, or cause its Williams Group Affiliates to repay, all such
outstanding Indebtedness of the Company and its Williams Group Affiliates (and
terminate all commitments to extend such Indebtedness), or obtain the requisite
consents, if any, under all agreements governing such Indebtedness or
commitments to permit the repurchase of Notes required by paragraph (a) of this
Section. The Company shall first comply with this paragraph (b) before it shall
be required to make a Change of Control Offer or to repurchase Notes pursuant to
paragraph (a). The Company's failure to comply with paragraph (b) may (with
notice and lapse of time) constitute an Event of Default under Section
5.01(a)(iv) but shall not constitute an Event of Default under Section
5.01(a)(iii).

         (c) The Company will publicly announce the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment
Date.

         SECTION 3.12.  Limitation on Asset Sales. (a) The Company will not, and
will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale
unless:

                                       53

<PAGE>

                  (i) the Company (or the Restricted Subsidiary, as the case may
         be) receives consideration at the time of the Asset Sale at least equal
         to the fair market value of the assets or Equity Interests issued or
         sold or otherwise disposed of;

                  (ii) the fair market value is determined by (a) an executive
         officer of the Company if the value is less than $10 million or (b) the
         Company's Board of Directors if the value is $10 million or more, as
         evidenced by a resolution of such Board of Directors;

                  (iii) at least 75% of the consideration received in the Asset
         Sale by the Company or such Restricted Subsidiary is in the form of
         cash or Cash Equivalents. For purposes of this provision, each of the
         following will be deemed to be cash:

                      (A) any liabilities, as shown on the Company's or such
                  Restricted Subsidiary's most recent balance sheet, of the
                  Company or any Restricted Subsidiary (other than contingent
                  liabilities and liabilities that are by their terms
                  subordinated to the Notes or any Subsidiary Guarantee) that
                  are assumed by the transferee of any such assets pursuant to a
                  customary novation agreement that releases the Company or such
                  Subsidiary from further liability;

                      (B) any securities, notes or other obligations received by
                  the Company or any such Restricted Subsidiary from such
                  transferee that are contemporaneously, subject to ordinary
                  settlement periods, converted by the Company or such
                  Subsidiary into cash, to the extent of the cash received in
                  that conversion; and

                      (C) property or assets received as consideration for such
                  Asset Sale that would otherwise constitute a permitted
                  application of Net Proceeds (or other cash in such amount)
                  under clauses (ii), (iii) or (iv) under paragraph (b) of this
                  Section.

         (b) Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply an amount of cash equal to the amount of such Net
Proceeds at its option:

                  (i) to repay or prepay senior Indebtedness of the Company
         and/or the Guarantors under a Credit Facility;

                  (ii) to acquire all or substantially all of the assets of, or
         a majority of the Voting Stock of, another Permitted Business;

                  (iii) to make a capital expenditure; or

                                       54

<PAGE>

                  (iv) to acquire other long-term assets that are used or useful
         in a Permitted Business.

         (c) Subject to paragraph (e) of this Section, to the extent that the
Company does not apply an amount of cash equal to the amount of such Net
Proceeds of any Asset Sale during such period as provided in paragraph (b) of
this Section, the amount not so applied (excluding Net Proceeds of any Asset
Sale of the Gray's Harbor lateral project and excluding Net Proceeds of any
Asset Sale to the extent of the amount of acquisitions or capital expenditures
described under clauses (ii), (iii) or (iv) under paragraph (b) of this Section
made during the 365 days preceding the receipt of such Net Proceeds (other than
any portion of such amount that was funded with Net Proceeds of any other Asset
Sale or that has been allocated to exclude Net Proceeds of any other Asset Sales
under this provision)) will constitute "EXCESS PROCEEDS." When the aggregate
amount of Excess Proceeds exceeds $20.0 million, the Company will make an Asset
Sale Offer to all Holders of Notes and all holders of other Indebtedness that is
pari passu with the Notes containing provisions similar to those set forth in
the Indenture with respect to offers to purchase or redeem with the proceeds of
sales of assets to purchase the maximum principal amount of Notes and such other
pari passu Indebtedness that may be purchased out of the Excess Proceeds (each
such offer an "ASSET SALE OFFER"). The offer price in any Asset Sale Offer will
be equal to 100% of the principal amount plus accrued and unpaid interest and
Liquidated Damages, if any, to the date of purchase, and will be payable in
cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer,
the Company may use those Excess Proceeds for any purpose not otherwise
prohibited by the Indenture. If the aggregate principal amount of Notes and
other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the
amount of Excess Proceeds, the Trustee will select the Notes and such other pari
passu Indebtedness to be purchased on a pro rata basis. Upon completion of each
Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

         (d) The Company will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with each
repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with the Asset Sale
provisions of the Indenture, the Company will comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations under this Section 3.12 by virtue of such conflict.

         (e) Prior to making any Asset Sale Offer, but in any event within 30
days following the date on which such Asset Sale Offer would otherwise be
required, if the Company or any of its Williams Group Affiliates is subject to
any agreement evidencing Indebtedness (or commitments to extend Indebtedness)
that prohibits

                                       55

<PAGE>

prepayment or repurchase of the Notes pursuant to an Asset Sale Offer, the
Company will either repay, or cause its Williams Group Affiliates to repay, all
such outstanding Indebtedness of the Company and its Williams Group Affiliates
(and terminate all commitments to extend such Indebtedness), or obtain the
requisite consents, if any, under all agreements governing such Indebtedness or
commitments to permit the repurchase of Notes required by this Section 3.12. The
Company shall first comply with this paragraph (e) before it shall be required
to make an Asset Sale Offer or to repurchase Notes pursuant to this Section. The
Company's failure to comply with the covenant described in this paragraph may
(with notice and lapse of time) constitute an Event of Default under 5.01(a)(iv)
but shall not constitute an Event of Default under Section 5.01(a)(iii).

         SECTION 3.13.  Limitation on Transactions with Affiliates. (a) The
Company will not, and will not permit any of its Restricted Subsidiaries to,
make any payment to, or sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or assets from, or enter into
or make or amend any transaction, contract, agreement, understanding, loan,
advance or guarantee with, or for the benefit of, any Affiliate (each, an
"AFFILIATE TRANSACTION"), unless:

                  (i) the 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 Affiliate Transactions involving aggregate
                  consideration in excess of $10 million, a resolution of the
                  Board of Directors of the Company set forth in an Officers'
                  Certificate certifying that such Affiliate Transaction
                  complies with this Section 3.13 and that such Affiliate
                  Transaction has been approved by a majority of the
                  disinterested members of the Board of Directors of the
                  Company; and

                      (B) with respect to any Affiliate Transaction or series of
                  related Affiliate Transactions involving aggregate
                  consideration in excess of $25 million, an opinion as to the
                  fairness to the Company of such Affiliate Transaction from a
                  financial point of view issued by an accounting, appraisal or
                  investment banking firm of national standing.

         (b) The following items will not be deemed to be Affiliate Transactions
and, therefore, will not be subject to the provisions of the prior paragraph:

                                       56

<PAGE>

                  (i) any employment agreement on customary terms entered into
         by the Company or any of its Restricted Subsidiaries in the ordinary
         course of business of the Company or such Restricted Subsidiary;

                  (ii) transactions between or among the Company and/or its
         Restricted Subsidiaries;

                  (iii) transactions with a Person that is an Affiliate of the
         Company solely because the Company owns an Equity Interest in, or
         controls, such Person;

                  (iv) payment of reasonable directors fees and provision to
         directors, officers and employees of customary indemnities and
         customary benefits pursuant to employee benefit plans and similar
         arrangements;

                  (v) sales of Equity Interests (other than Disqualified Stock)
         to Affiliates of the Company;

                  (vi) (A) corporate sharing agreements with the Company's
         Williams Group Affiliates and their subsidiaries with respect to tax
         sharing and general overhead and other administrative matters and (B)
         any other intercompany arrangements disclosed or described in the
         Company's report on Form 10-K for the fiscal year ended December 31,
         2001 (including the exhibits thereto) or the Offering Memorandum, all
         as in effect on the date of the Indenture, and any amendment or
         replacement of any of the foregoing so long as such amendment or
         replacement agreement is not less advantageous to the Company in any
         material respect than the agreement so amended or replaced, as such
         agreement was in effect on the date of the Indenture;

                  (vii) transactions entered into as part of a Permitted
         Receivables Financing; and

                  (viii) Restricted Payments that are permitted by the
         provisions of Section 3.05.

         SECTION 3.14.  Designation of Restricted and Unrestricted Subsidiaries.
The Board of Directors of the Company may designate any Restricted Subsidiary to
be an Unrestricted Subsidiary if that designation would not cause a Default;
provided that in no event will the businesses operated by the Company on the
date of this Indenture be transferred to or held by an Unrestricted Subsidiary.
If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the
aggregate fair market value of all outstanding Investments owned by the Company
and its Restricted Subsidiaries in the Subsidiary properly designated will be
deemed to be

                                       57

<PAGE>

an Investment made as of the time of the designation and will reduce the amount
available for Restricted Payments under Section 3.05(a) or Permitted
Investments, as determined by the Company. That designation will only be
permitted if the Investment would be permitted at that time and if the
Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary. The Board of Directors of the Company may redesignate any
Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would
not cause a Default.

         SECTION 3.15.  Limitation on Sale and Leaseback Transactions. The
Company will not, and will not permit any of its Restricted Subsidiaries to,
enter into any Sale and Leaseback Transaction; provided that the Company or any
Guarantor may enter into a Sale and Leaseback Transaction if:

                  (i) the Company or that Guarantor, as applicable, could have
         incurred Indebtedness in an amount equal to the Attributable Debt
         relating to such Sale and Leaseback Transaction under the Fixed Charge
         Coverage Ratio test in Section 3.06(a);

                  (ii) immediately after giving effect to such Sale and
         Leaseback Transaction, the aggregate outstanding Attributable Debt with
         respect to all Sale and Leaseback Transactions by the Company and the
         Guarantors does not exceed 10% of the Consolidated Net Tangible Assets
         of the Company; and

                  (iii) the gross cash proceeds of that Sale and Leaseback
         Transaction are at least equal to the fair market value, as determined
         in good faith by the Board of Directors of the Company and set forth in
         an Officers' Certificate delivered to the Trustee, of the property that
         is the subject of that Sale and Leaseback Transaction;

provided, however, that the foregoing clauses (i) and (ii) shall no longer be
applicable after any Investment Grade Date.

         SECTION 3.16. Business Activities. The Company will not, and will not
permit any Restricted Subsidiary to, engage in any business other than Permitted
Businesses, except to such extent as would not be material to the Company and
its Subsidiaries taken as a whole.

         SECTION 3.17. Payments for Consent. The Company will not, and will not
permit any of its Subsidiaries to, directly or indirectly, pay or cause to be
paid any consideration to or for the benefit of any Holder of Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of the Indenture or the Notes unless such consideration is offered to be paid
and is paid to all Holders of the Notes that consent, waive or agree to amend in
the time frame

                                       58

<PAGE>

set forth in the solicitation documents relating to such consent, waiver or
agreement.

                                   ARTICLE 4

                         CONSOLIDATION, MERGER AND SALE

         SECTION 4.01.  Limitation on Mergers and Consolidations. (a) The
Company may not, directly or indirectly: (1) consolidate or merge with or into
another Person (whether or not the Company is the surviving Person); or (2)
sell, assign, transfer, convey or otherwise dispose of all or substantially all
of the properties or assets of the Company and its Restricted Subsidiaries taken
as a whole, in one or more related transactions, to another Person unless:

                  (i) either: (a) the Company is the surviving Person; or (b)
         the Person formed by or surviving any such consolidation or merger (if
         other than the Company) or to which such sale, assignment, transfer,
         conveyance or other disposition has been made is a Person organized or
         existing under the laws of the United States, any state of the United
         States or the District of Columbia;

                  (ii) the Person formed by or surviving any such consolidation
         or merger (if other than the Company) or the Person to which such sale,
         assignment, transfer, conveyance or other disposition has been made
         expressly assumes by Supplemental Indenture all the obligations of the
         Company under the Notes, this Indenture and any Registration Rights
         Agreement and delivers to the Trustee an Opinion of Counsel to the
         effect that the Supplemental Indenture has been duly authorized,
         executed and delivered by such Person and constitutes a valid and
         binding obligation of such Person, enforceable against such Person in
         accordance with its terms (subject to customary exceptions);

                  (iii) immediately after such transaction no Default or Event
         of Default exists; and

                  (iv) the Company or the Person formed by or surviving any such
         consolidation or merger (if other than the Company), or to which such
         sale, assignment, transfer, conveyance or other disposition has been
         made will, on the date of such transaction after giving pro forma
         effect thereto and any related financing transactions as if the same
         had occurred at the beginning of the applicable four-quarter period, be
         permitted to incur at least $1.00 of additional Indebtedness pursuant
         to the Fixed Charge Coverage Ratio test set forth in Section 3.06(a);
         provided, however, that

                                       59

<PAGE>

         this clause (iv) shall no longer be applicable from and after any
         Investment Grade Date.

         (b) In addition, the Company may not, directly or indirectly, lease all
or substantially all of its properties or assets, in one or more related
transactions, to any other Person. Clause (iv) under paragraph (a) of this
Section will not apply to a sale, assignment, transfer, conveyance or other
disposition of assets between or among the Company and any of its Restricted
Subsidiaries. Without limitation of the foregoing, in no event shall the
Company, directly or indirectly, (1) consolidate or merge with or into Williams
or any of the Williams Group Affiliates (whether or not the Company is the
surviving Person) or (2) sell, assign, transfer, convey or otherwise dispose of
all or substantially all of the properties or assets of the Company and its
Restricted Subsidiaries taken as a whole, in one or more related transactions,
to Williams or any of the Williams Group Affiliates (other than mergers or
transactions otherwise permitted by this Section 4.01 with (a) Williams Group
Affiliates engaged in no businesses other than being principally engaged in
owning and operating regulated interstate natural gas pipeline systems and any
businesses incidental and reasonably related thereto, including facilities for
mainline transmission and gas storage ("PIPELINE BUSINESS") or (b) a holding
company of the Company engaged in no businesses other than Pipeline Business and
having no Subsidiaries other than Subsidiaries engaged in no businesses other
than Pipeline Business, and in the case of (a) or (b), only if at the time of
such merger or transaction, the Company and such Williams Group Affiliate or
holding company each have an Investment Grade Rating from Moody's and S&P and
the surviving Person will have an Investment Grade Rating from Moody's and S&P).

         SECTION 4.02.  Successors Substituted. In case of any such
consolidation, merger, sale, lease or conveyance, and following such an
assumption by the successor Person, such successor Person shall succeed to and
be substituted for the Company, with the same effect as if it had been named
herein. Such successor Person may cause to be signed, and may issue either in
its own name or in the name of the Company prior to such succession any or all
of the Notes issuable hereunder which theretofore shall not have been signed by
the Company and delivered to the Trustee; and, upon the order of such successor
Person, instead of the Company, and subject to all the terms, conditions and
limitations in the Indenture prescribed, the Trustee shall authenticate and
shall deliver any Notes which previously shall have been signed and delivered by
the officers of the Company to the Trustee for authentication, and any Notes
which such successor Person thereafter shall cause to be signed and delivered to
the Trustee for that purpose. All of the Notes so issued shall in all respects
have the same legal rank and benefit under the Indenture as the Notes
theretofore or thereafter issued in accordance with the terms of the Indenture
as though all of such Notes had been issued at the date of the execution hereof.

                                       60

<PAGE>

         In case of any such consolidation, merger, sale, lease or conveyance
such changes in phrasing and form (but not in substance) may be made in the
Notes thereafter to be issued as may be appropriate. In the event of any such
sale or conveyance (other than a conveyance by way of lease) the Company or any
successor Person which shall theretofore have become such in the manner
described in this Article shall be discharged from all obligations and covenants
under the Indenture, and the Notes and may be liquidated and dissolved.

         SECTION 4.03.  Consolidation, Merger or Sale of Assets by a Guarantor.
(a) No Guarantor may:

                  (i) consolidate with or merge with or into any Person, or

                  (ii) sell, convey, transfer or dispose of, all or
         substantially all its assets as an entirety or substantially as an
         entirety, in one transaction or a series of related transactions, to
         any Person, or

                  (iii) permit any Person to merge with or into the Guarantor

         unless

                      (A) immediately after giving effect to the transaction, no
                  Default or Event of Default exists; and

                      (B) either:

         (b) (i) the Person acquiring the property in any such sale or
disposition or the Person formed by or surviving any such consolidation or
merger (if other than such Guarantor) assumes all the obligations of that
Guarantor under the Indenture, its Subsidiary Guarantee and any Registration
Rights Agreement pursuant to a Supplemental Indenture satisfactory to the
Trustee; or

                  (ii) in connection with any sale or other disposition of all
         or substantially all of the assets of the Guarantor (including by way
         of merger or consolidation) to a Person that is not (either before or
         after giving effect to such transaction) a Subsidiary of the Company,
         if the sale or other disposition complies with Section 3.12.

                                       61

<PAGE>

                  (i) default for 30 days in the payment when due of interest
         on, or Liquidated Damages with respect to, the Notes;

                  (ii) default in payment when due of the principal of, or
         premium, if any, on the Notes;

                  (iii) failure by the Company to purchase Notes tendered
         pursuant to an offer described under Sections 3.11 and 3.12 in
         accordance with the terms thereof, or failure of the Company or any
         Guarantor to comply with the provisions of Article IV;

                  (iv) failure by the Company or any of its Restricted
         Subsidiaries for 60 days after notice, from the Trustee or the Holders
         of at least 25% of the outstanding principal amount of the Notes, to
         comply with any of the other agreements in the Indenture;

                  (v) default under any mortgage, indenture or instrument under
         which there may be issued or by which there may be secured or evidenced
         any Indebtedness for money borrowed by the Company or any of its
         Restricted Subsidiaries (or the payment of which is guaranteed by the
         Company or any of its Restricted Subsidiaries) whether such
         Indebtedness or guarantee now exists, or is created after the date of
         the Indenture, if that default:

                      (A) is caused by a failure of the Company or any
                  Subsidiary of the Company to pay principal of such
                  Indebtedness prior to the expiration of the grace period
                  provided in such Indebtedness on the date of such default (a
                  "PAYMENT DEFAULT"); or

                      (B) results in the acceleration of such Indebtedness prior
                  to its express maturity,

         and, in each case, the principal amount of any such Indebtedness,
         together with the principal amount of any other such Indebtedness under
         which there has been a Payment Default or the maturity of which has
         been so accelerated, aggregates $15 million or more;

                  (vi) failure by the Company or any of its Subsidiaries to pay
         final judgments aggregating in excess of $15 million, which judgments
         are not paid, discharged or stayed for a period of 60 days;

                  (vii) except as permitted by the Indenture, any Subsidiary
         Guarantee shall be held in any judicial proceeding to be unenforceable
         or invalid or shall cease for any reason to be in full force and effect
         or any

                                       62

<PAGE>

         Guarantor, or any Person acting on behalf of any Guarantor, shall deny
         or disaffirm its obligations under its Subsidiary Guarantee; and

                  (viii) the entry by a court having jurisdiction in the
         premises of (A) a decree or order for relief in respect of the Company
         or any of its Restricted Subsidiaries in an involuntary case or
         proceeding under any applicable Federal or State bankruptcy,
         insolvency, reorganization or other similar law or (B) a decree or
         order adjudging the Company or any of its Restricted Subsidiaries a
         bankrupt or insolvent, or approving as properly filed a petition
         seeking reorganization, arrangement, adjustment or composition of or in
         respect of the Company or any of its Restricted Subsidiaries under any
         applicable Federal or State law, or appointing a custodian, receiver,
         liquidator, assignee, trustee, sequestrator or other similar official
         of the Company or any of its Restricted Subsidiaries or of any
         substantial part of the property of the Company or any of its
         Restricted Subsidiaries, or ordering the winding up or liquidation of
         the affairs of the Company or any of its Restricted Subsidiaries, and
         the continuance of any such decree or order for relief or any such
         other decree or order unstayed and in effect for a period of 90
         consecutive days; or

                  (ix) the commencement by the Company or any of its Restricted
         Subsidiaries of a voluntary case or proceeding under any applicable
         Federal or State bankruptcy, insolvency, reorganization or other
         similar law or of any other case or proceeding to be adjudicated a
         bankrupt or insolvent, or the consent by it to the entry of a decree or
         order for relief in respect of the Company or any of its Restricted
         Subsidiaries in an involuntary case or proceeding under any applicable
         Federal or State bankruptcy, insolvency, reorganization or other
         similar law or to the commencement of any bankruptcy or insolvency case
         or proceeding against it, or the filing by it of a petition or answer
         or consent seeking reorganization or relief under any applicable
         Federal or State law, or the consent by it to the filing of such
         petition or to the appointment of or taking possession by a custodian,
         receiver, liquidator, assignee, trustee, sequestrator or similar
         official of the Company or any of its Restricted Subsidiaries or of any
         substantial part of the property of the Company or any of its
         Restricted Subsidiaries, or the making by it of an assignment for the
         benefit of creditors, or the admission by it in writing of its
         inability to pay its debts generally as they become due, or the taking
         of corporate action by the Company or any of its Restricted
         Subsidiaries in furtherance of any such action.

         (b) The Trustee shall not be deemed to know of a Default or Event of
Default unless a Responsible Officer at the Corporate Trust Office of the
Trustee has actual knowledge of such Default or Event of Default or the Trustee
receives written notice at the Corporate Trust Office of the Trustee of such
Default or

                                       63

<PAGE>

Event of Default with specific reference to such Default or Event of Default and
the Notes and this Indenture.

         (c) When a Default is cured, or when an Event of Default is deemed
cured pursuant to Section 5.04, such Default, or Event of Default, as the case
may be, ceases.

         SECTION 5.02.  Acceleration. If an Event of Default (other than an
Event of Default specified in clause (viii) or (ix) of Section 5.01(a) hereof
with respect to the Company, any Subsidiary that is a Significant Subsidiary or
any group of Subsidiaries that, taken together, would constitute a Significant
Subsidiary) occurs and is continuing, the Trustee by notice to the Company, or
the Holders of at least 25% in principal amount of the then outstanding Notes by
notice to the Company and the Trustee, may declare the principal of and premium,
if any, and accrued and unpaid interest and Liquidated Damages, if any, on all
then outstanding Notes to be due and payable immediately. Upon any such
declaration the amounts due and payable on the Notes, as determined in
accordance with the next succeeding paragraph, shall be due and payable
immediately. If an Event of Default specified in clause (viii) or (ix) of
Section 5.01(a) with respect to the Company, any Subsidiary that is a
Significant Subsidiary or any group of Subsidiaries that, taken together, would
constitute a Significant Subsidiary, occurs, the principal of and premium, if
any, and accrued and unpaid interest and Liquidated Damages, if any, on all
Notes then outstanding shall ipso facto become and be immediately due and
payable without any declaration, notice or other act on the part of the Trustee
or any Holder.

         At any time after such a declaration of acceleration with respect to
the Notes has been made and before a judgment for payment of the money due has
been obtained by the Trustee as hereinafter in this Article provided, the
Holders of a majority in principal amount of the outstanding Notes, by written
notice to the Company and the Trustee, may rescind and annul such declaration
and its consequences if:

                  (i) all existing Events of Default, other than the nonpayment
         of the principal of, premium, if any, and interest on the Notes that
         have become due solely by the declaration of acceleration, have been
         cured or waived, and

                  (ii) the rescission would not conflict with any judgment or
         decree of a court of competent jurisdiction.

         No such rescission shall affect any subsequent Default or impair any
right consequent thereon.

                                       64

<PAGE>

         If the maturity of the Notes is accelerated pursuant to this Section
5.02, 100% of the principal amount thereof shall become due and payable plus
premium, if any, and accrued interest and Liquidated Damages, if any, to the
date of payment.

         In the case of any Event of Default occurring by reason of any willful
action or inaction taken or not taken by or on behalf of the Company with the
intention of avoiding payment of the premium (including, in the case of any such
Event of Default prior to March 1, 2007, payment of the Make-Whole Price) that
the Company would have had to pay if the Company then had elected to redeem the
Notes pursuant to the optional redemption provisions of the Indenture, an
equivalent premium (or, in the case of any such Event of Default prior to March
1, 2007, the relevant Make-Whole Amount that would apply at such time if the
Notes were optionally redeemed at the Make-Whole Price) will also become and be
immediately due and payable to the extent permitted by law upon the acceleration
of the Notes.

         SECTION 5.03.  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, Liquidated Damages, if any, or interest on
the Notes or to enforce the performance of any provision of the Notes, the
Indenture or any Registration Rights Agreement.

         The Trustee may maintain a proceeding even if it does not possess any
of the Notes 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 5.04.  Waiver of Existing Defaults. Subject to Sections 5.07
and 8.02 hereof, the Holders of a majority in aggregate principal amount of the
outstanding Notes by notice to the Trustee may waive an existing Default or
Event of Default and its consequences (including waivers obtained in connection
with a purchase of, or tender offer or exchange offer for, the Notes or a
solicitation of consents in respect of the Notes), except (1) a continuing
Default or Event of Default in the payment of interest or Liquidated Damages on,
or the principal of, the Notes or (2) a continuing Default in respect of a
provision that under Section 8.02 hereof cannot be amended without 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 the Indenture; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon.

                                       65

<PAGE>

         SECTION 5.05.  Control by Majority. The Holders of a majority in
principal amount of the Notes then outstanding 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 hereunder. However, the Trustee
may refuse to follow any direction that conflicts with applicable law or the
Indenture, that the Trustee determines may be unduly prejudicial to the rights
of other Holders, or that may involve the Trustee in personal liability;
provided, however, that the Trustee may take any other action deemed proper by
the Trustee that is not inconsistent with such direction. Prior to taking any
action hereunder, the Trustee shall be entitled to indemnification satisfactory
to it in its sole discretion against all losses and expenses caused by taking or
not taking such action.

         SECTION 5.06.  Limitations on Suits. Subject to Section 5.07 hereof, a
Holder may pursue a remedy with respect to the Indenture or the Notes only if:

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

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

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

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

                  (v) during such 60-day period the Holders of a majority in
         principal amount of the Notes do not give the Trustee a direction
         inconsistent with the request.

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

         SECTION 5.07.  Rights of Holders to Receive Payment. Notwithstanding
any other provision of the Indenture, the right of any Holder of a Note to
receive payment of principal of, and premium, if any, and interest on the Note,
on or after the respective due dates expressed in the Note, or to bring suit for
the enforcement of any such payment on or after such respective dates, is
absolute and unconditional and shall not be impaired or affected without the
consent of such Holder.

                                       66

<PAGE>

         SECTION 5.08.  Collection Suit by Trustee. If an Event of Default
specified in clause (i) or (ii) of Section 5.01 hereof occurs and is continuing,
the Trustee is authorized to recover judgment in its own name and as trustee of
an express trust against the Company for the amount of principal and premium, if
any, and interest (and Liquidated Damages, if any) remaining unpaid on the
Notes, and interest on overdue principal, premium, if any, and Liquidated
Damages, if any and, to the extent lawful, interest on overdue interest (and
Liquidated Damages, if any), and such further amount as shall be sufficient to
cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

         SECTION 5.09.  Trustee May File Proofs of Claim. The Trustee is
authorized to file such proofs of claim and other papers or documents and to
take such actions, including participating as a member, voting or otherwise, of
any committee of creditors, as may be necessary or advisable in order to have
the claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel) and
the Holders allowed in any judicial proceedings relative to the Company or its
creditors or properties and shall be entitled and empowered to collect, receive
and distribute any money or other property payable or deliverable on any such
claims and any Custodian in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee, and in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 6.07 hereof. To the extent that
the payment of any such compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.07 hereof 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, and shall be
paid out of, any and all distributions, dividends, money, securities 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. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

         SECTION 5.10.  Priorities. If the Trustee collects any money pursuant
to this Article, it shall pay out the money in the following order:

         First: to the Trustee (including any Predecessor Trustee) for amounts
due under Section 6.07 hereof;

                                       67

<PAGE>

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

         Third: to the Company.

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

         SECTION 5.11.  Undertaking for Costs. In any suit for the enforcement
of any right or remedy under the 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 and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by a Holder pursuant to Section 5.07 hereof, or a
suit by a Holder or Holders of more than 10% in principal amount of the Notes
then outstanding.

                                   ARTICLE 6

                                    TRUSTEE

         SECTION 6.01.  Duties of Trustee. (a) If an Event of Default has
occurred and is continuing, the Trustee shall exercise such of the rights and
powers vested in it by the Indenture, and use the same degree of care and skill
in such exercise, as a prudent man would exercise or use under the circumstances
in the conduct of his own affairs.

         (b) Except during the continuance of an Event of Default:

                  (i) the Trustee need perform only those duties that are
         specifically set forth in the Indenture and no others, and no implied
         covenants or obligations shall be read into the 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
         the Indenture. However, with respect to certificates or opinions
         specifically required by

                                       68

<PAGE>

         any provision hereof to be furnished to it, the Trustee shall examine
         such certificates and opinions to determine whether or not, on their
         face, they appear to conform substantially to the requirements of the
         Indenture.

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

                  (i) this paragraph does not limit the effect of paragraphs (b)
         or (e) of this Section;

                  (ii) the Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible 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 received by it pursuant to Section 5.05 hereof.

         (d) Whether or not therein expressly so provided, every provision of
the Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b), (c) and (e) of this Section.

         (e) No provision of the Indenture shall require the Trustee to expend
or risk its own funds or incur any liability.

         (f) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree in writing with the Company. Money held in
trust by the Trustee need not be segregated from other funds except to the
extent required by law. All money received by the Trustee shall, until applied
as herein provided, be held in trust for the payment of the principal of, and
premium if any, and interest on the Notes.

         SECTION 6.02.  Rights of Trustee. (a) The Trustee may rely conclusively
and shall be fully protected in acting or refraining from acting on any document
(whether in its original or facsimile form) believed by it to be genuine and to
have been signed or presented by the proper Person. The Trustee need not
investigate any fact or matter stated in the document.

         (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate 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 of its own selection and the advice of such counsel or any Opinion of
Counsel shall be full and complete authorization and protection in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon.

                                       69

<PAGE>

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

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

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

         (f) The Trustee is not required to give any bond or surety with respect
to the performance of its duties or the exercise of its powers under the
Indenture.

         (g) The Trustee's immunities and protections from liability and its
right to indemnification in connection with the performance of its duties under
the Indenture shall extend and be enforceable by the Trustee in each of its
capacities hereunder and shall extend to the Trustee's officers, directors,
agents, attorneys and employees. Such immunities and protections and right to
indemnity, together with the Trustee's right to compensation, shall survive the
Trustee's resignation or removal, the discharge of the Indenture and final
payment of the Notes.

         (h) The permissive right of the Trustee to take the actions permitted
by the Indenture shall not be construed as an obligation or duty to do so.

         (i) Except for information provided by the Trustee concerning the
Trustee, the Trustee shall have no responsibility for any information in any
offering memorandum or other disclosure material distributed with respect to the
Notes, and the Trustee shall have no responsibility for compliance with any
state or federal securities laws in connection with the Notes.

         (j) The Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to the Indenture,
which Officers' Certificate may be signed by any person authorized to sign an
Officers' Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded.

         (k) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by the Indenture at the request or direction of
any of the Holders pursuant to the Indenture, unless such Holders shall have
offered to the Trustee security or indemnity satisfactory to the Trustee against
the costs,

                                       70

<PAGE>

expenses and liabilities which might be incurred by it in compliance with such
request or direction.

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

         SECTION 6.03.  Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and
may otherwise deal with the Company or any of its Affiliates with the same
rights it would have if it were not Trustee. Any Agent may do the same with like
rights. However, the Trustee is subject to Sections 6.10 and 6.11 hereof.

         SECTION 6.04.  Trustee's Disclaimer. The Trustee makes no
representation as to the validity or adequacy of the Indenture or the Notes, it
shall not be accountable for the Company's use of the proceeds from the Notes or
any money paid to the Company or upon the Company's direction under any
provision hereof, it shall not be responsible for the use or application of any
money received by any Paying Agent other than the Trustee and it shall not be
responsible for any statement or recital herein or any statement in the Notes
other than its certificate of authentication.

         SECTION 6.05.  Notice of Defaults. If a Default or Event of Default
occurs and is continuing and it is actually known to a Responsible Officer of
the Trustee, the Trustee shall mail to Holders a notice of the Default or Event
of Default within 90 days after it occurs. Except in the case of a Default or
Event of Default in payment of principal of, or premium, if any, Liquidated
Damages, if any, or interest on any Note, the Trustee may withhold the notice if
and so long as a committee of its Responsible Officers in good faith determines
that withholding the notice is in the interests of Holders.

         SECTION 6.06.  Reports by Trustee to Holders. On or before May 15 of
each year, beginning with May 15, 2004, the Trustee shall mail to Holders a
brief report dated as of a date convenient to the Trustee no more than 60 nor
less than 45 days prior thereto, that complies with TIA Section 313(a);
provided, however, that if no event described in TIA Section 313(a) has occurred
within the twelve months preceding the reporting date, no report need be
transmitted. The Trustee also shall comply with TIA Section 313(b). The Trustee
shall also transmit by mail all reports as required by TIA Sections 313(c) and
313(d).

         A copy of each report at the time of its mailing to Holders shall be
filed with the Commission and each securities exchange, if any, on which the
Notes are listed. The Company shall notify the Trustee if and when the Notes are
listed on any stock exchange or delisted therefrom.

         SECTION 6.07.  Compensation and Indemnity. The Company agrees to pay to
the Trustee from time to time such compensation as agreed to by the Company and
the Trustee, for its acceptance of the Indenture and its services hereunder. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company agrees to reimburse the Trustee upon
request for all reasonable disbursements, advances and expenses incurred by it.
Such expenses shall include the reasonable compensation, disbursements and
expenses of the Trustee's agents and counsel.

         The Company agrees to fully indemnify the Trustee or any predecessor
Trustee and their agents for and to hold them harmless against any and all loss,
liability damage, claims, or expense (including taxes, other than taxes based
upon, measured by or determined by the income of the Trustee) incurred by it
arising out of or in connection with the acceptance or administration of its
duties under the Indenture, including the costs and expenses of defending itself
against any claim (whether asserted aby the Company, any Holder or any other
Person), except as set forth in the next paragraph. The Trustee shall notify the
Company promptly of any claim for which it may seek indemnity. The Company shall
defend the claim and the Trustee shall cooperate in the defense. The Trustee may
have separate counsel, and the Company shall pay the reasonable fees and
expenses of such counsel. The Company need not pay for any settlement made
without its consent, which consent shall not be unreasonably withheld.

         The Company shall not be obligated to reimburse any expense or
indemnify against any loss or liability incurred by the Trustee through its own
negligence or willful misconduct.

         To secure the payment obligations of the Company in this Section 6.07,
the Trustee shall have a lien prior to the Notes on all money or property held
or collected by the Trustee, except that held in trust to pay principal of, and
premium, if any, and interest and Liquidated Damages, if any, on particular
Notes. Such lien shall survive the satisfaction and discharge of the Indenture,
the resignation or removal of the Trustee and the termination of this Indenture
for any reason.

         Without prejudice to its rights hereunder, when the Trustee incurs
expenses or renders services after an Event of Default specified in Section
5.01(a)(viii) or (ix) hereof occurs, the expenses and the compensation for the
services are intended to constitute expenses of administration under any
Bankruptcy Law.

         SECTION 6.08.  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
6.08.

                                       72

<PAGE>

         The Trustee may resign and be discharged from the trust hereby created
by so notifying the Company. The Holders of a majority in principal amount of
the then outstanding Notes may remove the Trustee by so notifying the Trustee
and the Company. The Company may remove the Trustee if:

                  (i) the Trustee fails to comply with Section 6.10 hereof;

                  (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 otherwise becomes incapable of acting.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the Notes then outstanding may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.

         If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of at least 10% in principal amount of the Notes then outstanding may
petition (at the expense of the Company) any court of competent jurisdiction at
the expense of the Company for the appointment of a successor Trustee.

         If the Trustee fails to comply with Section 6.10 hereof, 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 the Company. 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 the Indenture. The successor Trustee shall mail a notice of its succession
to Holders. The retiring Trustee shall promptly transfer all property held by it
as Trustee to the successor Trustee, subject to the lien provided for in Section
6.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section
6.08 hereof, the obligations of the Company under Section 6.07 hereof shall
continue for the benefit of the retiring Trustee.

         SECTION 6.09.  Successor Trustee by Merger, Etc. Subject to Section
6.10 hereof, if the Trustee consolidates, merges or converts into, or transfers
all or

                                       73

<PAGE>

substantially all of its corporate trust business to, another Person, the
successor Person without any further act shall be the successor Trustee.

         In case any Notes shall have been authenticated, but not delivered, by
the Trustee then in office, any successor by merger, conversion or consolidation
to such authenticating Trustee may adopt such authentication and deliver the
Notes so authenticated; and in case at that time any of the Notes shall not have
been authenticated, any successor to the Trustee may authenticate such Notes
either in the name of any predecessor hereunder or in the name of the successor
to the Trustee; and in all such cases such certificates shall have the full
force which it is anywhere in the Notes or in the Indenture provided that the
certificate of the Trustee shall have.

         SECTION 6.10.  Eligibility; Disqualification. There shall at all times
be a Trustee hereunder which shall be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia and authorized under such laws to exercise corporate trust
power, shall be subject to supervision or examination by Federal or State (or
the District of Columbia) authority and shall have, or be a Subsidiary of a bank
or bank holding company having, a combined capital and surplus of at least $50
million as set forth in its most recent published annual report of condition.

         This Indenture shall always have a Trustee who satisfies the
requirements of TIA Sections 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee is
subject to and shall comply with the provisions of TIA Section 310(b) during the
period of time required by the Indenture. For purposes of Section 301(b)(1) of
the TIA and to the extent permitted thereby, the Trustee shall not be deemed to
have a conflicting interest arising from its capacity as trustee in respect of
any series of securities issued under the Indentures dated as of August 1, 1992,
November 30, 1995 and December 8, 1997, each by and between the Company and
JPMorgan Chase Bank (or its predecessor), as trustee, and any other indentures
of the Company pursuant to which JPMorgan Chase Bank acts as trustee. Nothing in
the Indenture shall prevent the Trustee from filing with the SEC the application
referred to in the penultimate paragraph of TIA Section 310(b).

         SECTION 6.11.  Preferential Collection of Claims Against Company. The
Trustee is subject to and shall comply with the provisions of TIA Section
311(a), excluding any creditor relationship listed in TIA Section 311(b). A
Trustee who has resigned or been removed shall be subject to TIA Section 311(a)
to the extent indicated therein.

         stolen or destroyed Notes that have been replaced or paid and Notes for
         whose payment money has been deposited in trust and thereafter repaid
         to the Company, have been delivered to the Trustee for cancellation; or

                  (B) all Notes that have not been delivered to the Trustee for
         cancellation have become due and payable by reason of the mailing of a
         notice of redemption or otherwise or will become due and payable within
         one year and the Company or any Guarantor has irrevocably deposited or
         caused to be deposited with the Trustee as trust funds in trust solely
         for the benefit of the Holders, cash in U.S. dollars, non-callable
         Government Securities, or a combination of cash in U.S. dollars and
         noncallable Government Securities, in amounts as will be sufficient
         without consideration of any reinvestment of interest, to pay and
         discharge the entire indebtedness on the Notes not delivered to the
         trustee for cancellation for principal, premium and Liquidated Damages,
         if any, and accrued interest to the date of maturity or redemption;

                  (ii) the Company or any Guarantor has paid or caused to be
         paid all sums payable by it under the Indenture; and

                  (iii) the Company has delivered irrevocable instructions to
         the Trustee under the Indenture to apply the deposited money toward the
         payment of the Notes at the Maturity Date or the Redemption Date, as

                  (iv) the Company has delivered to the Trustee an Officers'
         Certificate stating that all conditions precedent to satisfaction and
         discharge of the Indenture have been complied with, together with an
         Opinion of Counsel to the same effect.

         (b) After satisfying the conditions in clauses (a)(i)(A),(ii),(iii) and
(iv), only the Company's obligations under Section 6.07 will survive. After
satisfying the conditions in clauses (a)(i)(B), (ii), (iii) and (iv), only the

<PAGE>

obligations in Article II and Sections 3.01, 3.02, 6.07, 6.08, 7.05 and 7.06
will survive. In either case, the Trustee upon request will acknowledge in
writing the discharge of the Company's obligations under the Notes and the
Indenture other than the surviving obligations.

         SECTION 7.02.  Legal Defeasance. (a) After the 91st day following the
deposit referred to in clause (i), the Company will be deemed to have paid and
will be discharged from its obligations in respect of the Notes and the
Indenture, other than its obligations in Article II and Sections 3.01, 3.02,
6.07, 6.08, 7.05 and 7.06, and each Guarantor's obligations under its Subsidiary
Guarantee will terminate ("LEGAL DEFEASANCE"), provided the following conditions

                  (i) the Company must irrevocably deposit with the Trustee, in
         trust, for the benefit of the Holders of the Notes, cash in U.S.
         dollars, non- callable Government Securities, or a combination of cash
         in U.S. dollars and non-callable Government Securities, in amounts as
         will be sufficient, in the opinion of a nationally recognized firm of
         independent public accountants, to pay the principal of, or interest
         and premium and Liquidated Damages, if any, on the outstanding Notes on
         the Stated Maturity or on the applicable Redemption Date, as the case
         may be, and the Company must specify whether the Notes are being
         defeased to Maturity Date or to a particular Redemption Date;

                  (ii) the Company has delivered to the Trustee an Opinion of
         Counsel reasonably acceptable to the Trustee confirming that (a) the

         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 Notes 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;

                  (iii) no Default or Event of Default has occurred and is
         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);

                  (iv) such Legal Defeasance will not result in a breach or
         violation of, or constitute a default under any material agreement or
         instrument (other than the Indenture) to which the Company or any of
         its Subsidiaries is a party or by which the Company or any of its
         Subsidiaries is bound;

                                       76

<PAGE>

                  (v) the Company must deliver to the Trustee an Officers'
         Certificate stating that the deposit was not made by the Company with
         the intent of preferring the Holders of Notes over the other creditors
         of the Company with the intent of defeating, hindering, delaying or
         defrauding creditors of the Company or others; and

                  (vi) the Company must deliver to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent relating to the Legal Defeasance have been complied with.

obligations under the Indenture will be discharged. Thereafter, the Trustee upon
request will acknowledge in writing the discharge of the Company's obligations
under the Notes and the Indenture except for the surviving obligations specified
above.

         SECTION 7.03.  Covenant Defeasance. (a) After the 91st day following
the deposit referred to in clause (i), the Company's obligations set forth in
Sections 3.03 through 3.17, inclusive and clause (iv) of Section 4.01(a), and
each Guarantor's obligations under its Subsidiary Guarantee, will terminate, and
clauses (iii), (iv), (v), (vi) and (vii) of Section 5.01(a) will no longer
constitute Events of Default ("COVENANT DEFEASANCE"), provided the following
conditions have been satisfied:

                  (i) the Company must irrevocably deposit with the Trustee, in
         trust, for the benefit of the Holders of the Notes, cash in U.S.
         dollars, non- callable Government Securities, or a combination of cash
         in U.S. dollars and non-callable Government Securities, in amounts as
         will be sufficient, in the opinion of a nationally recognized firm of
         independent public accountants, to pay the principal of, or interest
         and premium and Liquidated Damages, if any, on the outstanding Notes on
         the Stated Maturity or on the applicable Redemption Date, as the case
         may be, and the Company must specify whether the Notes are being
         defeased to Maturity Date or to a particular Redemption Date;

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

                  (iii) no Default or Event of Default has occurred and is
         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);

                                       77

<PAGE>

                  (iv) such Covenant Defeasance will not result in a breach or
         violation of, or constitute a default under any material agreement or
         instrument (other than the Indenture) to which the Company or any of
         its Subsidiaries is a party or by which the Company or any of its
         Subsidiaries is bound;

                  (v) the Company must deliver to the Trustee an Officers'
         Certificate stating that the deposit was not made by the Company with

         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent relating to the Legal Defeasance have been complied with.

         Except as specifically stated above, none of the Company's obligations
under the Indenture will be discharged.

         SECTION 7.04.  Covenant Termination. From and after the first date
after the date of the Indenture on which the Notes have an Investment Grade
Rating from both Rating Agencies and no Default or Event of Default has occurred
and is continuing under the Indenture (the "INVESTMENT GRADE DATE"), the Company
and its Restricted Subsidiaries will no longer be subject to Sections 3.05,
3.06, 3.08, 3.09, 3.12, 3.13 and 3.16 of the Indenture.

         SECTION 7.05.  Application of Trust Money. The Trustee or a trustee
satisfactory to the Trustee and the Company shall hold in trust money or U.S.
Government Obligations deposited with it pursuant to Section 7.01, 7.02 and 7.03
hereof. It shall apply the deposited money and the money from U.S. Government
Obligations through the Paying Agent and in accordance with the Indenture to the
payment of principal of, premium, if any, Liquidated Damages, if any, and
interest on the Notes.

         SECTION 7.06.  Repayment to Company. The Trustee and the Paying Agent
shall promptly pay to the Company upon written request any excess money or
securities held by them at any time.

         Subject to the requirements of any applicable abandoned property laws,
the Trustee and the Paying Agent shall pay to the Company upon written request
any money held by them for the payment of principal, premium, if any, Liquidated
Damages, if any, or interest that remains unclaimed for two years after the date
upon which such payment shall have become due; provided, however, that the
Company shall have either caused notice of such payment to be mailed to each

                                       78

<PAGE>

Holder entitled thereto no less than 30 days prior to such repayment or within
such period shall have published such notice in a financial newspaper of
widespread circulation published in The City of New York. After payment to the
Company, Holders entitled to the money must look to the Company for payment as
general creditors unless an applicable abandoned property law designates another
Person, and all liability of the Trustee and the Paying Agent with respect to
such money shall cease.

         In the absence of a written request from the Company to return
unclaimed funds to the Company, the Trustee shall from time to time deliver all
unclaimed funds to or as directed by applicable escheat authorities, as
determined by the Trustee in its sole discretion, in accordance with customary
practices and procedures of the Trustee. Any unclaimed funds held by the Trustee
pursuant to this Section 7.06 shall be held uninvested and without any liability
for interest.

         SECTION 7.07.  Reinstatement. If the Trustee or the Paying Agent is
unable to apply any money or U. S. Government Obligations in accordance with
Section 7.01, 7.02 or 7.03 hereof by reason of any legal proceeding or by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the obligations of the
Company under the Indenture and the Notes shall be revived and reinstated as
though no deposit had occurred pursuant to Section 7.01, 7.02 or 7.03 hereof
until such time as the Trustee or the Paying Agent is permitted to apply all
such money or U. S. Government Obligations in accordance with Section 7.01, 7.02
or 7.03 hereof; provided, however, that if the Company has made any payment of
principal of or interest on any Notes because of the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Notes to receive such payment from the money or U.S. Government Obligations
held by the Trustee or the Paying Agent.

                                    ARTICLE 8

and the Trustee may amend or supplement the Indenture or any of the Notes or

                  (i)   to cure any ambiguity, omission, defect or
         inconsistency;

                  (ii)  to provide for uncertificated Notes in addition to or
         in place of certificated Notes;

                                       79

<PAGE>

                  (iii) to provide for the assumption of the Company's
         obligations to Holders of Notes in the case of a merger or
         consolidation or sale of all or substantially all of the Company's
         assets;

                  (iv)  to provide for any Guarantee of the Notes, to secure
         the Notes or to confirm and evidence the release, termination or
         discharge of any Guarantee of or Lien securing the Notes when such
         release, termination or discharge is permitted by the Indenture;

                  (v)   to make any change that would provide any additional
         rights or benefits to the Holders of Notes or that does not adversely
         affect the legal rights under the Indenture of any such Holder; or to
         provide for the acceptance of appointment hereunder of a successor
         Trustee in compliance with the provisions hereof;

                  (vi)  to comply with requirements of the Commission under the
         Securities Act or the Exchange Act or in order to effect or maintain
         the qualification of the Indenture under the Trust Indenture Act.

         Upon the request of the Company accompanied by a resolution of the
Board of Directors of the Company authorizing the execution of any such
Supplemental Indenture, and upon receipt by the Trustee of the documents
described in and subject to the other terms of Section 8.06 hereof, the Trustee
shall join with the Company in the execution of any Supplemental Indenture
authorized or permitted by the terms of the Indenture and make any further
appropriate agreements and stipulations that may be therein contained. After an
amendment, supplement or waiver under this Section 8.01 becomes effective, the
Company shall mail to the Holders of each Note affected thereby a notice briefly
describing the amendment, supplement or waiver. Any failure of the Company to
mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such Supplemental Indenture.

         SECTION 8.02.  With Consent of Holders.

         Except as provided below in this Section 8.02, the Company and the
Trustee may amend or supplement the Indenture or the Notes with the written
consent (including consents obtained in connection with a purchase of, or tender
offer or exchange offer for, the Notes or a solicitation of consents in respect
of the Notes) of the Holders of at least a majority in principal amount of the
Notes then outstanding.

         Upon the request of the Company accompanied by a resolution of the
Board of Directors of the Company authorizing the execution of any such
Supplemental Indenture, and upon the filing with the Trustee of evidence of the
consent of the Holders as aforesaid, and upon receipt by the Trustee of the

                                       80

<PAGE>

documents described in Section 8.06 hereof, the Trustee shall join with the
Company in the execution of such Supplemental Indenture.

         It shall not be necessary for the consent of the Holders under this
Section 8.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

         The Holders of a majority in principal amount of the Notes then
outstanding may waive compliance in a particular instance by the Company with
any provision of the Indenture or the Notes (including waivers obtained in
connection with a purchase of, tender offer or exchange offer for, the Notes or
a solicitation of consents in respect of the Notes).

         Without the consent of each Holder affected, an amendment, supplement
or waiver under this Section may not:

                  (i)   reduce the principal amount of Notes whose Holders must
         consent to an amendment, supplement or waiver;

                  (ii)  reduce the principal of or change the fixed maturity of
         any Note or alter the provisions (including without limitation the
         amount of any premium or the price therefor) with respect to the
         redemption of the Notes (other than provisions relating to Sections
         3.11 and 3.12);

                  (iii) reduce the rate of or change the time for payment of
         interest or Liquidated Damages on any Note;

                  (iv)  waive a Default or Event of Default in the payment of
         principal of, or interest or premium, or Liquidated Damages, if any, on
         the Notes (except a rescission of acceleration of the Notes by the
         Holders of at least a majority in aggregate principal amount of the
         Notes and a waiver of the payment default that resulted from such
         acceleration);

                  (v)   make any Note payable in money other than that stated in
         the Notes;

                  (vi)  make any change in the provisions of the Indenture
         relating to waivers of past Defaults or the rights of Holders of Notes
         to receive payments of principal of, or interest or premium or
         Liquidated Damages, if any, on the Notes;

                  (vii) waive a redemption payment with respect to any Note
         (other than a payment required by Sections 3.11 or 3.12);

                                       81

<PAGE>

                  (viii) release any Guarantor from any of its obligations under
         its Subsidiary Guarantee or the Indenture, except in accordance with
         the terms of the Indenture; or

                  (ix)  make any change in the preceding amendment and waiver
         provisions.

         The right of any Holder to participate in any consent required or
sought pursuant to any provision of the Indenture (and the obligation of the
Company to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of the Notes with respect to which such consent is required or sought as of a
date identified by the Trustee in a notice furnished to Holders in accordance
with the terms of the Indenture.

         SECTION 8.03.  Compliance with Trust Indenture Act. Every amendment to
the Indenture or the Notes shall comply in form and substance with the TIA as
then in effect.

         SECTION 8.04.  Revocation and Effect of Consents. A consent to an
amendment (which includes a supplement) or waiver by a Holder is a continuing
consent by the Holder and every subsequent Holder of a Note or portion of a Note
that evidences the same debt as the consenting Holder's Note, even if notation
of the consent is not made on any Note. However, any such Holder or subsequent
Holder may revoke the consent as to his or her Note or portion of a Note if the
Trustee receives written notice of revocation at any time prior to (but not
after) the date the Trustee receives an Officers' Certificate certifying that
the Holders of the requisite principal amount of Notes have consented (and not
theretofore revoked such consent) to the amendment, supplement or waiver. An
amendment, supplement or waiver becomes effective in accordance with its terms
and thereafter binds every Holder.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment or
waiver or to take any other action under the Indenture. If a record date is
fixed, then notwithstanding the provisions of the immediately preceding
paragraph, those Persons who were Holders at such record date (or their duly
designated proxies), and only those Persons, shall be entitled to consent to
such amendment, supplement or waiver or to revoke any consent previously given,
whether or not such Persons continue to be Holders 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 the Notes required
hereunder for such amendment or waiver to be effective shall have also been
given and not revoked within such 90-day period.

                                       82

<PAGE>

         After an amendment, supplement or waiver becomes effective, it shall
bind every Holder, unless it is of the type described in any of clauses (i)
through (ix) of Section 8.02 hereof. In such case, the amendment or waiver shall
bind each Holder who has consented to it and every subsequent Holder that
evidences the same debt as the consenting Holder's Note.

         SECTION 8.05.  Notation on or Exchange of Notes. If an amendment
changes the terms of a Note, the Trustee may require the Holder of the Note to
deliver it to the Trustee. The Trustee may place an appropriate notation on the
Note regarding the changed terms and return it to the Holder. Alternatively, if
the Company or the Trustee so determines, the Company in exchange for the Note
shall issue and the Trustee shall authenticate a new Note that reflects the
changed terms. Failure to make the appropriate notation or to issue a new Note
shall not affect the validity of such amendment.

         SECTION 8.06.  Trustee to Sign Amendments, Etc. The Trustee shall sign
any amendment, waiver or Supplemental Indenture authorized pursuant to this
Article if the amendment, waiver or Supplemental Indenture 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 or refusing to sign such
amendment, waiver or Supplemental Indenture, the Trustee shall receive, and
subject to Section 6.01 hereof, shall be fully protected in relying upon, an
Opinion of Counsel and an Officers' Certificate, as conclusive evidence that
such amendment, waiver or Supplemental Indenture is authorized or permitted by
the Indenture, that it is not inconsistent herewith, and that it will be valid
and binding upon the Company in accordance with its terms.

                                    ARTICLE 9

                                   REDEMPTION

         SECTION 9.01.  Notices to Trustee. If the Company elects to redeem
Notes pursuant to the redemption provisions of Section 9.07, it shall furnish to
the Trustee, at least 45 days but not more than 60 days before a Redemption Date
(unless the Trustee consents in writing to a shorter period of at least 30 days
prior to the Redemption Date), an Officers' Certificate setting forth the
Redemption Date, the principal amount of such Notes to be redeemed and the
Redemption Price.

         SECTION 9.02.  Selection of Notes to Be Redeemed. (a) If less than all
of the Notes are to be redeemed at any time, the Trustee will select Notes for
redemption as follows:

                                       83

<PAGE>

                  (i)   if the Notes are listed on any national securities
         exchange, in compliance with the requirements of the principal national
         securities exchange on which the Notes are listed; or

                  (ii)  if the Notes are not listed on any national securities
         exchange, on a pro rata basis, by lot or by such method as the Trustee
         deems fair and appropriate.

         The particular Notes to be redeemed shall be selected, unless otherwise
provided herein, not less than 30 days nor more than 60 days prior to the
Redemption Date by the Trustee from the outstanding Notes not previously called
for redemption.

         The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of
them selected shall be in amounts of $1,000 or whole multiples of $1,000. Except
as provided in the preceding sentence, provisions of the Indenture that apply to
Notes called for redemption also apply to portions of Notes called for
redemption.

         SECTION 9.03.  Notices to Holders. (a) At least 30 days but not more
than 60 days before a Redemption Date, the Company shall mail in conformity with
Section 11.02 a notice of redemption to each Holder whose Notes are to be
redeemed, except that redemption notices may be mailed more than 60 days prior
to a redemption date if the notice is issued in connection with a defeasance of
the Notes or a satisfaction and discharge of the Indenture. Notices of
redemption may not be conditional.

         The Notice shall identify the Notes to be redeemed (including CUSIP
numbers, if any) and shall state:

                  (i)   the Redemption Date;

                  (ii)  the Redemption Price;

                  (iii) if any Note is being redeemed in part, the portion of
         the principal amount of such Note to be redeemed and that, after the
         Redemption Date, upon surrender of such Note, a new Note or Notes in
         principal amount equal to the unredeemed portion will be issued;

                  (iv)  the name and address of the Paying Agent;

                  (v)   that Notes called for redemption must be surrendered to
         the Paying Agent at the address specified in such notice to collect the
         Redemption Price;

                                       84

<PAGE>

                  (vi)  that unless the Company defaults in making the
         redemption payment, interest on Notes called for redemption ceases to
         accrue on and after the Redemption Date and the only remaining right of
         the Holders is to receive payment of the Redemption Price upon
         surrender to the Paying Agent of the Notes; and

                  (vii) the aggregate principal amount of Notes being redeemed.

         If any of the Notes to be redeemed is in the form of a Global Note,
then the Company shall modify such notice to the extent necessary to accord with
the procedures of the Depositary applicable to redemptions.

         (b) At the Company's request, the Trustee shall give the notice
required in Section 9.03(a) in the Company's name; provided, however, that the
Company shall deliver to the Trustee, at least 45 days prior to the Redemption
Date (unless the Trustee consents in writing to a shorter period at least 30
days prior to the Redemption Date), an Officers' Certificate requesting that the
Trustee give such notice and setting forth the information to be stated in such
notice as provided in Section 9.03(a).

         SECTION 9.04.  Effect of Notices of Redemption. Once notice of
redemption is mailed pursuant to Section 9.03, Notes called for redemption
become due and payable on the Redemption Date at the Redemption Price. Upon
surrender to the Paying Agent, such Notes shall be paid out at the Redemption
Price.

         SECTION 9.05.  Deposit of Redemption Price. At or prior to 11:00 am New
York City time on the Redemption Date, the Company shall deposit with the
Trustee or with the Paying Agent money sufficient to pay the Redemption Price of
all Notes to be redeemed on that date. The Trustee or the Paying Agent shall
return to the Company any money not required for that purpose less the expenses
of the Trustee as provided herein.

         If the Company complies with the preceding paragraph, interest on the
Notes or portions thereof to be redeemed (whether or not such Notes are
presented for payment) will cease to accrue on the applicable Redemption Date.
If any Note called for redemption shall not be so paid upon surrender because of
the failure of the Company to comply with the preceding paragraph, then interest
will be paid on the unpaid principal and premium, if any, from the Redemption
Date until such principal and premium are paid and, to the extent lawful, on any
interest not paid on such unpaid principal, in each case at the rate provided in
the Notes and in Section 3.01.

         SECTION 9.06.  Notes Redeemed in Part. Upon surrender of a Note that is
redeemed in part, the Company shall issue and the Trustee shall authenticate for
the Holder, at the expense of the Company, a new Note equal in principal amount
to the unredeemed portion of the Note surrendered.

         SECTION 9.07.  Optional Redemption. (a) At any time and from time to
time prior to March 1, 2007, the Company may, at its option, redeem all or a
portion of the Notes at the Make-Whole Price plus accrued and unpaid interest to
the redemption date.

         (b) At any time and from time to time on or after March 1, 2007, the
Company may, at its option, redeem the Notes, in whole or in part, at a
redemption price equal to the percentage of principal amount set forth below

         offer will be required to surrender such Note at the place or places
         specified in the offer prior to the close of business on the Change of
         Control Payment Date (such Note being, if the Company or the Trustee so
         requires, duly endorsed or accompanied by a duly executed written
         instrument of transfer);

                                       87

                  (xi) Holders are entitled to withdraw Notes tendered by giving

Payment for such Notes, and the Trustee will promptly return to Holders any
Notes not accepted for purchase and send to Holders new Notes equal in principal
amount to any unpurchased portion of any Notes accepted for purchase in part,

                                   ARTICLE 10

                                   GUARANTIES

         SECTION 10.01.  The Guaranties. Subject to the provisions of this
Article, each Guarantor hereby irrevocably and unconditionally guarantees,
jointly and severally, on an unsecured basis, the full and punctual payment
(whether at Stated Maturity, upon redemption, purchase pursuant to an Change of
Control Offer or acceleration, or otherwise) of the principal of, premium, if
any, and interest on, and all other amounts payable under, each Note, and the
full and punctual payment of all other amounts payable by the Company under the
Indenture. Upon failure by the Company to pay punctually any such amount, each
Guarantor shall forthwith on demand pay the amount not so paid at the place and
in the manner specified in the Indenture.

         SECTION 10.02.  Guarantee Unconditional. The obligations of each
Guarantor hereunder are unconditional and absolute and, without limiting the
generality of the foregoing, will not be released, discharged or otherwise
affected by

                  (i) any extension, renewal, settlement, compromise, waiver or
         release in respect of any obligation of the Company under the Indenture
         or any Note, by operation of law or otherwise;

                  (ii) any modification or amendment of or supplement to the
         Indenture or any Note;

                                       89

<PAGE>

                  (iii) any change in the corporate existence, structure or
         ownership of the Company, or any insolvency, bankruptcy, reorganization
         or other similar proceeding affecting the Company or its assets or any
         resulting release or discharge of any obligation of the Company
         contained in the Indenture or any Note;

                  (iv) the existence of any claim, set off or other rights which
         the Guarantor may have at any time against the Company, the Trustee or
         any other Person, whether in connection with the Indenture or any
         unrelated transactions, provided that nothing herein prevents the
         assertion of any such claim by separate suit or compulsory
         counterclaim;

                  (v) any invalidity or unenforceability relating to or against
         the Company for any reason of the Indenture or any Note, or any
         provision of applicable law or regulation purporting to prohibit the
         payment by the Company of the principal of or interest on any Note or
         any other amount payable by the Company under the Indenture; or

                  (vi) any other act or omission to act or delay of any kind by
         the Company, the Trustee or any other Person or any other circumstance
         whatsoever which might, but for the provisions of this paragraph,
         constitute a legal or equitable discharge of or defense to such
         Guarantor's obligations hereunder.

         SECTION 10.03   Discharge; Reinstatement. Each Guarantor's obligations
hereunder will remain in full force and effect until the principal of, premium,
if any, and interest on the Notes and all other amounts payable by the Company
under the Indenture have been paid in full. If at any time any payment of the
principal of, premium, if any, or interest on any Note or any other amount
payable by the Company under the Indenture is rescinded or must be otherwise
restored or returned upon the insolvency, bankruptcy or reorganization of the
Company or otherwise, each Guarantor's obligations hereunder with respect to
such payment will be reinstated as though such payment had been due but not made
at such time.

         SECTION 10.04.  Waiver by the Guarantors. Each Guarantor irrevocably
waives acceptance hereof, presentment, demand, protest and any notice not
provided for herein, as well as any requirement that at any time any action be
taken by any Person against the Company or any other Person.

         SECTION 10.05. Subrogation and Contribution. Upon making any payment
with respect to any obligation of the Company under this Article, the Guarantor
making such payment will be subrogated to the rights of the payee against the
Company with respect to such obligation, provided that the Guarantor may not
enforce either any right of subrogation, or any right to receive payment in the
nature of contribution, or otherwise, from any other Guarantor, with respect to

                                       90

<PAGE>

such payment so long as any amount payable by the Company hereunder or under the
Notes remains unpaid.

         SECTION 10.06.  Stay of Acceleration. If acceleration of the time for
payment of any amount payable by the Company under the Indenture or the Notes is
stayed upon the insolvency, bankruptcy or reorganization of the Company, all
such amounts otherwise subject to acceleration under the terms of the Indenture
are nonetheless payable by the Guarantors hereunder forthwith on demand by the
Trustee or the Holders.

         SECTION 10.07.  Limitation on Amount of Guarantee. Notwithstanding
anything to the contrary in this Article, each Guarantor, and by its acceptance
of Notes, each Holder, hereby confirms that it is the intention of all such
parties that the Subsidiary Guarantee of such Guarantor not constitute a
fraudulent conveyance under applicable fraudulent conveyance provisions of the
United States Bankruptcy Code or any comparable provision of state law. To
effectuate that intention, the Trustee, the Holders and the Guarantors hereby
irrevocably agree that the obligations of each Guarantor under its Subsidiary
Guarantee are limited to the maximum amount that would not render the
Guarantor's obligations subject to avoidance under applicable fraudulent
conveyance provisions of the United States Bankruptcy Code or any comparable
provision of state law.

         SECTION 10.08.  Execution and Delivery of Guarantee. The execution by
each Guarantor of the Indenture (or a Supplemental Indenture in the form of
Exhibit B) evidences the Subsidiary Guarantee of such Guarantor, whether or not
the person signing as an officer of the Guarantor still holds that office at the
time of authentication of any Note. The delivery of any Note by the Trustee
after authentication constitutes due delivery of the Subsidiary Guarantee set
forth in the Indenture on behalf of each Guarantor.

         SECTION 10.09.  Release of Guarantee. The Subsidiary Guarantee of a
Guarantor will terminate upon

                  (i)  any sale or other disposition of all or substantially all
         of the assets of that Guarantor (including by way of merger or
         consolidation) to a Person that is not (either before or after giving
         effect to such transaction) a Subsidiary of the Company, if the sale or
         other disposition complies with Section 3.12; or

                  (ii) the sale or other disposition of all of the Capital Stock
         of a Guarantor to a Person that is not (either before or after giving
         effect to such transaction) a Subsidiary of the Company, if the sale or
         other disposition complies with Section 3.12; or

                  (iii) the Company designating any Restricted Subsidiary that
         is a Guarantor as an Unrestricted Subsidiary in accordance with the
         applicable provisions of the Indenture; or

                  (iv)  defeasance or discharge of the Notes, as provided in
         Article

         VII.

         Upon delivery by the Company to the Trustee of an Officers' Certificate
and an Opinion of Counsel to the foregoing effect, the Trustee will execute any
documents reasonably required in order to evidence the release of the Guarantor
from its obligations under its Subsidiary Guarantee.

         SECTION 11.01.  Trust Indenture Act Controls. If any provision of the
Indenture limits, qualifies or conflicts with another provision which is
required to be included in the Indenture by the TIA, the required provision
shall control. If the Indenture excludes any provision of the TIA that is
required to be included, such provision shall be deemed included herein.

         SECTION 11.02.  Notices. Any notice or communication by the Company or
the Trustee to the other is duly given if in writing and delivered in person or
mailed by mail (registered or certified, return receipt requested), telecopier

reason of any other cause, it shall be impossible to mail any notice required by
the Indenture, then such method of notification as shall be made with the
approval of the Trustee shall constitute a sufficient mailing of such notice.

         SECTION 11.3.  Communication by Holders with Other Holders. Holders may
communicate pursuant to TIA Section 312(b) with other Holders with respect to
their rights under the Indenture or the Notes. The Company, the Trustee, the

in the Indenture shall bind its successors.

         SECTION 11.12. Severability. In case any provision in the Indenture or

of copies of the Indenture. Each signed copy shall be an original, but all of

                 8 1/8% Series [A/Exchange] Senior Note due 2010

         This Note is one of a duly authorized issue of 8 1/8% Series
[A/Exchange] Senior Notes due 2010 (the "Notes") of Northwest Pipeline
Corporation, a Delaware corporation (the "Company").

         1.       Interest. The Company promises to pay interest on the
principal amount of this Note at 8 1/8% per annum from March 4, 2003 until
maturity. The Company will pay interest semiannually on March 1 and September 1
of each year (each an "Interest Payment Date"), or if any such day is not a
Business Day, on the next succeeding Business Day, to the holder of record at
the close of business on February 15 or August 15 immediately preceding such
Interest Payment Date. Interest on the Notes will accrue from the most recent
Interest Payment Date on which interest has been paid or, if no interest has
been paid, from March 4, 2003; provided that if there is no existing Default in
the payment of interest, and if this Note is authenticated between a record date
referred to on the face hereof and the next succeeding Interest Payment Date,
interest shall accrue from such next succeeding Interest Payment Date; provided,
further, that the first Interest Payment Date shall be September 1, 2003.
Further, the Company shall pay interest on overdue principal and premium, if
any, from time to time on demand at a rate equal to the interest rate then in
effect; it shall pay interest on overdue installments of interest (without
regard to any applicable grace periods) from time to time on demand at the same
rate to the extent lawful. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

         [The Holder of this Note is entitled to the benefits of a registration
rights agreement, dated as of March 4, 2003, between the Company and the Initial
Purchasers named therein (the "Registration Rights Agreement"). In the event
that a Registration Default (as defined in the Registration Rights Agreement)
occurs, liquidated damages ("Liquidated Damages") will accrue on the affected
Transfer Restricted Notes and the affected Private Exchange Notes, as
applicable. The rate of Liquidated Damages will be $0.05 per week per $1,000
principal amount of Transfer Restricted Notes and affected Private Exchange
Notes held by such Holder for the first 90-day period immediately following the
occurrence of a Registration Default, increasing by an additional $0.05 per week
per $1,000 principal amount of Transfer Restricted Notes and affected Private
Exchange Notes with respect to each subsequent 90-day period thereafter up to a
maximum amount of Liquidated Damages for all Registration Defaults of $0.50 per
week per $1,000 principal amount of Transfer Restricted Notes and affected
Exchange Notes, from and including the date on which any such Registration
Default shall occur to, but excluding, the earlier of (1) the date on which all
Registration Defaults have been cured or (2) the date on which all Transfer
Restricted Notes and Private Exchange Notes otherwise become freely
transferrable by Holders

Securities Act.]**

         2.       Ranking. The Notes are senior unsecured obligations of the
Company.

         3.       Redemption and Repurchase; Discharge Prior to Redemption or
Maturity. (a) At any time and from time to time prior to March 1, 2007, the
Company may, at its option, redeem the Notes, in whole or in part, at the
Make-Whole Price plus accrued and unpaid interest and Liquidated Damages, if
any, to the Redemption Date.

         "Make-Whole Amount" with respect to a Note means an amount equal to the
excess, if any, of (1) the present value of the remaining interest, premium and
principal payments due on such Note (excluding any portion of such payments of
interest accrued as of the Redemption Date), computed using a discount rate
equal to the Treasury Rate plus 50 basis points, over (2) the outstanding
principal amount of such Note.

         "Make-Whole Average Life" means the number of years (calculated to the
nearest one-twelfth) between the Redemption Date and the Stated Maturity of the
Notes.

         "Make-Whole Price" means the sum of the outstanding principal amount of
the Notes to be redeemed plus the Make-Whole Amount for such Notes.

         "Treasury Rate" is defined as the yield to maturity (calculated on a
semi-annual bond-equivalent basis) at the time of the computation of United
States Treasury securities with a constant maturity (as compiled by and
published in the most recent Federal Reserve Statistical Release H.15 (510),
which has become publicly available at least two business days prior to the date
of the redemption notice or, if such Statistical Release is no longer published,
any publicly available source of similar market data) most nearly equal to the
then remaining maturity of the Notes; provided that if the Make-Whole Average
Life of such note is not equal to the constant maturity of the United States
Treasury security for which a weekly average yield is given, the Treasury Rate
shall be obtained by linear interpolation (calculated to the nearest one-twelfth
of a year) from the weekly average yields of United States Treasury securities
for which such yields are given, except that if the Make-Whole Average Life of
such Note is less than one year, the weekly average yield on actually traded
United States Treasury securities adjusted to a constant maturity of one year
shall be used.

         (b) At any time and from time to time on or after March 1, 2007, the
Company may, at its option, redeem the Notes, in whole or in part, at a
redemption price equal to the percentage of their principal amount set forth
below plus accrued and unpaid interest and Liquidated Damages, if any, to the

subsidiaries may act in any such capacity.

time to time, the "Indenture") between the Company and the Trustee. The terms of
the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code Sections 77aaa-77bbbb), as in effect on the date of execution of the
Indenture (the "TIA"). The Notes are subject to all such terms, and Holders are
referred to the Indenture and such Act for a statement of such terms.

Registrar need not exchange or register the transfer of any Notes during the
period between a record date and the corresponding Interest Payment Date.

         7.       Persons Deemed Owners. The registered Holder of a Note shall
be treated as its owner for all purposes.

         8.       Amendments and Waivers. Subject to certain exceptions and
limitations, the Indenture or the Notes may be amended or supplemented with the
consent of the Holders of at least a majority in principal amount of the then

any provision of the Indenture may be waived (other than certain provisions,
including any continuing Default or Event of Default in the payment of the
principal of, or premium, if any, or interest on the Notes) by the Holders of at
least a majority in principal amount of the Notes then outstanding in accordance

merger, consolidation or sale of all or substantially all of the assets of the

provide any additional rights or benefits to the Holders of Notes or that does
not adversely affect the legal rights under the Indenture of any such Holder;

successor Trustee in compliance with the provisions of the Indenture; or (vii)
to comply with any requirements of the

Commission under the Securities Act or the Exchange Act or in order to effect or
maintain the qualification of the Indenture under the TIA.

         The right of any Holder to participate in any consent required or
sought pursuant to any provision of the Indenture (and the obligation of the
Company to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of any Notes with respect to which such consent is required or sought as of a
date identified by the Trustee in a notice furnished to Holders in accordance
with the terms of the Indenture.

         Without the consent of each Holder affected, an amendment, supplement
or waiver under the Indenture may not (i) reduce the principal amount of Notes
whose Holders must consent to an amendment, supplement or waiver, (ii) reduce
the rate of or change the time for payment of interest or Liquidated Damages on
any Note, (iii) reduce the principal of or change the fixed maturity of any Note

premium or the price thereunder) with respect to the redemption of the Notes
(other than as specified in Section 8.02 of the Indenture), (iv) make any Note
payable in money other than that stated in the Note, (v) make any change in the
provisions of the Indenture relating to waivers of past Defaults or the rights
of Holders of Notes to receive payments of principal of, or interest or premium
or Liquidated Damages, if any, on the Notes, (vi) waive a redemption payment
with respect to any Note (other than as specified in Section 8.02 of the
Indenture); (vii) release any Guarantor from any of its obligations under its
Subsidiary Guarantee or the Indenture, except in accordance with the terms of
the Indenture; or (viii) waive a Default or Event of Default in the payment of
principal of, or interest or premium, or Liquidated Damages, if any, on the
Notes (except a rescission of acceleration of the Notes by the Holders of at
least a majority in aggregate principal amount of the Notes and a waiver of the
payment default that resulted from such acceleration) or (ix) make any change in
the preceding amendment and waiver provisions.

         9.       Defaults and Remedies. Events of Default include: (i) default
in payment when due of interest or Liquidated Damages, if any, on the Notes for
30 days; (ii) default in payment when due of principal of, or premium, if any,
on the Notes; (iii) failure by the Company to purchase Notes tendered pursuant
to a Change of Control Offer or an Asset Sale Offer as described under and in
accordance with the terms of Sections 3.11 and 3.12 of the Indenture, or failure
of the Company or any Guarantor to comply with the provisions of Article IV of
the Indenture relating to mergers and consolidations, (iv) failure by the
Company or any of its Restricted Subsidiaries for 60 days after notice from the
Trustee or the Holders of at least 25% of the outstanding principal amount of
the Notes, to comply with any of the other agreements in the Indenture; (v)
certain defaults specified in Section 5.01(a)(v) of the Indenture under any
mortgage, indenture or instrument evidencing Indebtedness for money borrowed by
the Company or any of its Restricted Subsidiaries (or the payment of which is
guaranteed by the Company or any of its Restricted Subsidiaries); (vi) failure
by the Company or any of its Subsidiaries to pay final judgments aggregating in
excess of $15 million,

                                      A-8

<PAGE>

which judgments are not paid, discharged or stayed for a period of 60 days;
(vii) except as permitted by the Indenture, any Subsidiary Guarantee being held
in any judicial proceeding to be unenforceable or invalid or ceasing for any
reason to be in full force and effect or any Guarantor, or any Person acting on
behalf of any Guarantor, denying or disaffirming its obligations under its
Subsidiary Guarantee; and (viii) certain voluntary or involuntary events
specified in Sections 5.01(a)(viii) and 5.01(a)(ix) of the Indenture involving
bankruptcy, insolvency or reorganization of the Company. If an Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Notes may declare the principal of, and
premium, if any, and accrued and unpaid interest and Liquidated Damages, if any,
on all the Notes to be immediately due and payable, except that in the case of
an Event of Default arising from certain events of bankruptcy, insolvency or
reorganization of the Company, any Subsidiary that is a Significant Subsidiary
or any group of Subsidiaries that, taken together, would constitute a
Significant Subsidiary specified in Sections 5.01(a)(viii) and 5.01(a)(ix) of
the Indenture, all outstanding Notes will become due and payable immediately
without further action or notice. Holders may not enforce the Indenture or the
Notes except as provided in the Indenture. The Trustee may require indemnity
reasonably satisfactory to it before it enforces the Indenture or the Notes.
Subject to certain limitations, Holders of a majority in principal amount of the
then outstanding Notes 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 under the Indenture. The Trustee may withhold from Holders
notice of any continuing default (except a default in payment of principal or
premium, if any, or interest) if and so long as it determines that withholding
notice is in their interests. The Company must furnish an annual compliance
certificate to the Trustee.

         10.      Trustee Dealings with the Company. The Trustee, in its
individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company or its Affiliates, and may otherwise deal with
the Company or its Affiliates, as if it were not Trustee.

         11.      No Recourse Against Others. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Notes or the Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation. Each
Holder by accepting a Note waives and releases all such liability. The waiver
and release are part of the consideration for the issuance of the Notes.

         12.      Authentication. This Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

         13.      CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Note Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes as a convenience to the Holders of the
Notes. No representation is made as to the accuracy of such numbers as printed

                                      A-9

on the Notes and reliance may be placed only on the other identification numbers
printed thereon.

and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

         15.      Governing Law. The Indenture and the Notes shall be governed
by and constructed in accordance with, the laws of the State of New York.

         16.      [Additional Rights and Obligations of Holders of Transfer

                           the Transfer Restricted Securities surrendered by
                           such Holder.

<PAGE>

                  The Company shall use its commercially reasonable efforts to
         complete the Exchange Offer as provided above and shall comply with the
         applicable requirements of the 1933 Act, the 1934 Act and other
         applicable laws and regulations in connection with the Exchange Offer.
         The Exchange Offer shall not be subject to any conditions, other than
         that the Exchange Offer does not violate applicable law or any
         applicable interpretation of the Staff of the SEC. The Company shall
         inform the Initial Purchasers of the names and addresses of the Holders
         to whom the Exchange Offer is made, and the Initial Purchasers shall
         have the right, subject to applicable law, to contact such Holders and
         otherwise facilitate the tender of Transfer Restricted Securities in
         the Exchange Offer.

                  If, during the period the Exchange Offer Registration
         Statement is effective, an event occurs which makes any statement made
         in such Exchange Offer Registration Statement or the related Prospectus
         untrue in any material respect or which requires the making of any
         changes in such Exchange Offer Registration Statement or Prospectus in
         order to make the statements therein not misleading, the Company shall
         use its commercially reasonable efforts to prepare and file with the
         SEC a supplement or post-effective amendment to the Exchange Offer
         Registration Statement or the related Prospectus or any document
         incorporated therein by reference or file any other required document
         so that, as thereafter delivered to the purchasers of the Transfer
         Restricted Securities, such Prospectus will not contain any untrue
         statement of a material fact or omit to state a material fact necessary
         to make the statements therein, in light of the circumstances under
         which they were made, not misleading. The Company agrees to notify the
         Holders to suspend the exchange of the Transfer Restricted Securities
         as promptly as practicable after the occurrence of such an event, and
         the Holders hereby agree to suspend such exchange until the Company has
         amended or supplemented the Prospectus to correct such misstatement or
         omission.

                  (b) If (i) the Company is not (A) required to file the
         Exchange Offer Registration Statement or (B) permitted to consummate
         the Exchange Offer because the Exchange Offer is not permitted by
         applicable law or applicable interpretation of the Staff of the SEC; or
         (ii) any Holder of Transfer Restricted Securities notifies the Company
         prior to the 20th day following the consummation of the Exchange Offer
         that: (A) it is prohibited by law or applicable interpretation of the
         Staff of the SEC from participating in the Exchange Offer, (B) it may
         not resell the Exchange Securities acquired by it in the Exchange Offer
         to the public without delivering a Prospectus and the Prospectus
         contained in the Exchange Offer Registration Statement is not
         appropriate or available for such resales

                                       8

<PAGE>

         or (C) it is a broker-dealer and owns Securities acquired directly from
         the Company or an affiliate of the Company, the Company shall (x) use
         its commercially reasonable efforts to file with the SEC within 60 days
         after such filing obligation arises (or, if later, the date by which
         the Company is obligated to file an Exchange Offer Registration
         Statement) a Shelf Registration Statement providing for the resale by
         the Holders (other than those who fail to comply with the paragraph
         immediately following clause (p) of Section 3) of all of their Transfer
         Restricted Securities and (y) use its commercially reasonable efforts
         to cause such Shelf Registration Statement to become effective within
         180 days after such filing obligation arises (or, if later, the date by
         which the Company is obligated to use its commercially reasonable
         efforts to have the Exchange Offer Registration Statement declared
         effective). If the Company is required to file a Shelf Registration
         Statement solely as a result of the matters referred to in clause (ii)
         of the preceding sentence, the Company shall use it commercially
         reasonable efforts to file and have declared effective by the SEC both
         an Exchange Offer Registration Statement pursuant to Section 2(a) with
         respect to all Transfer Restricted Securities and a Shelf Registration
         Statement (which may be a combined Registration Statement with the
         Exchange Offer Registration Statement) with respect to reoffers and
         resales of Transfer Restricted Securities held by the Holders who must
         deliver the related Prospectus. Subject to the following paragraph, the
         Company agrees to use its commercially reasonable efforts to keep the
         Shelf Registration Statement continuously effective until the
         expiration of the period referred to in Rule 144(k) with respect to the
         Transfer Restricted Securities or such shorter period that will
         terminate when all of the Transfer Restricted Securities covered by the
         Shelf Registration Statement have been sold pursuant to the Shelf
         Registration Statement or cease to be Transfer Restricted Securities
         within the meaning of this Agreement. The Company further agrees to
         supplement or amend the Shelf Registration Statement if required by the
         rules, regulations or instructions applicable to the registration form
         used by the Company for such Shelf Registration Statement or by the
         1933 Act or by any other rules and regulations thereunder for shelf
         registration or if reasonably requested by a Holder with respect to
         information relating to such Holder, and to use its commercially
         reasonable efforts to cause any such amendment to become effective and
         such Shelf Registration Statement to become usable as soon as
         thereafter practicable. The Company agrees to furnish to the Holders of
         Transfer Restricted Securities copies of any such supplement or
         amendment promptly after its being used or filed with the SEC.

                  Notwithstanding anything to the contrary in this Agreement,
         the Company, upon advising the Initial Purchasers and each Holder, may
         suspend the use of the Prospectus included in any Shelf Registration

                                       9

         Statement in the event that and for periods of time not to exceed 30
         consecutive days and for no more than 60 days during any 365 day period
         in which such suspensions are in effect (each such period, a
         "SUSPENSION PERIOD") if (i) an event or circumstance occurs and is
         continuing as a result of which the Shelf Registration Statement, the
         related Prospectus or any document incorporated therein by reference as
         then amended or supplemented or proposed to be filed would, in the good
         faith judgment of the Company, contain an untrue statement of a
         material fact or omit to state a material fact necessary in order to
         make the statements therein, in light of the circumstances under which
         they were made, not misleading and (ii) (A) the Company determines in
         its good faith judgment that the disclosure of such event at such time
         would have a material adverse effect on the business, operations or
         prospects of the Company or (B) the disclosure otherwise relates to a
         material business transaction or development which has not been
         publicly disclosed; provided, however, that upon the termination of
         such Suspension Period, the Company shall promptly advise the Initial
         Purchasers and each Holder that such Suspension Period has been
         terminated.

                  (c) The Company shall pay all Registration Expenses in
         connection with the registration pursuant to Section 2(a) or Section
         2(b). Each Holder shall pay all underwriting discounts, if any, and
         commissions and transfer taxes, if any, relating to the sale or
         disposition of such Holder's Transfer Restricted Securities pursuant to
         a Shelf Registration Statement.

                  (d) An Exchange Offer Registration Statement pursuant to
         Section 2(a) hereof or a Shelf Registration Statement pursuant to
         Section 2(b) hereof will not be deemed to have become effective unless
         it has been declared effective by the SEC; provided, however, that, if,
         after it has been declared effective, the offering of Transfer
         Restricted Securities pursuant to a Shelf Registration Statement is
         interfered with by any stop order, injunction or other order or
         requirement of the SEC or any other governmental agency or court, such
         Registration Statement will be deemed not to have become effective
         during the period of such interference until the offering of Transfer
         Restricted Securities pursuant to such Registration Statement may
         legally resume.

                  (e) The Company and the Initial Purchasers agree that the
         Holders will suffer damages if the Company fails to fulfill its
         obligations under Section 2(a) or Section 2(b) hereof and that it would
         not be feasible to ascertain the extent of such damages with precision.
         Accordingly, the Company agrees that if:

                                       10

<PAGE>

                           (i)      the Exchange Offer Registration Statement is
                  not filed with the SEC on or prior to the 90th day following
                  the Closing Date,

                           (ii)     the Exchange Offer Registration Statement is
                  not declared effective on or prior to the 180th day following
                  the Closing Date,

                           (iii)    the Exchange Offer is not completed on or
                  prior to the 30th Business Day following the date the Exchange
                  Offer Registration Statement is declared effective, or

                           (iv)     the Shelf Registration Statement is required
                  to be filed but is not filed or declared effective within the
                  respective time periods set forth herein or is declared
                  effective but thereafter ceases to be effective or usable
                  (other than during a Suspension Period) prior to the
                  expiration of the period referred to in Rule 144(k) with
                  respect to the Transfer Restricted Securities other than after
                  the Transfer Restricted Securities have been disposed of under
                  the Shelf Registration Statement or cease to be Transfer
                  Restricted Securities, without being succeeded within two
                  Business Days by a post-effective amendment which cures the
                  failure and that is itself immediately declared effective,

         (each such event referred to in clauses (i) through (iv) a
         "REGISTRATION DEFAULT"), liquidated damages ("LIQUIDATED DAMAGES") will
         accrue on the affected Transfer Restricted Securities and the affected
         Exchange Securities, as applicable. The rate of Liquidated Damages will
         be $0.05 per week per $1,000 principal amount of Transfer Restricted
         Securities and affected Exchange Securities held by such Holder for the
         first 90-day period immediately following the occurrence of a
         Registration Default, increasing to by an additional $0.05 per week per
         $1,000 principal amount of Transfer Restricted Securities and affected
         Exchange Securities with respect to each subsequent 90-day period
         thereafter up to a maximum amount of Liquidated Damages for all
         Registration Defaults of $0.50 per week per $1,000 principal amount of
         Transfer Restricted Securities and affected Exchange Securities, from
         and including the date on which any such Registration Default shall
         occur to, but excluding, the earlier of (1) the date on which all
         Registration Defaults have been cured or (2) the date on which all the
         Transfer Restricted Securities and Exchange Securities otherwise become
         freely transferable by Holders other than affiliates of the Company
         without further registration under the 1933 Act.

                                       11

<PAGE>

                  Notwithstanding the foregoing, (1) the amount of Liquidated
         Damages payable shall not increase because more than one Registration
         Default has occurred and is pending and (2) a Holder of Transfer
         Restricted Securities or Exchange Securities who is not entitled to the
         benefits of the Shelf Registration Statement (i.e., such Holder has not
         elected to including information) shall not be entitled to Liquidated
         Damages with respect to a Registration Default that pertains to the
         Shelf Registration Statement.

                  (f) The Company shall notify the Trustee within one Business
         Day after each date on which an event occurs in respect of which
         Liquidated Damages are required to be paid. Any amounts of Liquidated
         Damages due pursuant to this Section 2 will be payable in addition to
         any other interest payable from time to time with respect to the
         Transfer Restricted Securities in cash semi-annually on the interest
         payment dates specified in the Indenture (to the holders of record as
         specified in the Indenture), commencing with the first such interest
         payment date occurring after any such Liquidated Damages commence to
         accrue. The amount of Liquidated Damages will be determined in a manner
         consistent with the calculation of interest under the Indenture.

                  (g) Without limiting the remedies available to the Holders,
         the Company acknowledges that any failure by the Company to comply with
         its obligations under Section 2(a) and Section 2(b) hereof may result
         in material irreparable injury to the Holders for which there is no
         adequate remedy at law, that it will not be possible to measure damages
         for such injuries precisely and that, in the event of any such failure,
         the Initial Purchasers or any Holder may obtain such relief as may be
         required to specifically enforce the Company's obligations under
         Section 2(a) and Section 2(b) hereof.

         3.    Registration Procedures.

         In connection with the obligations of the Company with respect to the
Registration Statements pursuant to Section 2(a) and Section 2(b) hereof, the
Company shall as expeditiously as possible (provided, however, that the Company
shall not be required to take actions more promptly than required by Sections
2(a) and 2(b)):

                  (a) prepare and file with the SEC a Registration Statement on
         the appropriate form under the 1933 Act, which form shall (x) be
         selected by the Company, (y) in the case of a Shelf Registration, be
         available for the sale of the Transfer Restricted Securities by the
         selling Holders thereof and (z) comply as to form in all material
         respects with the applicable

                                       12

<PAGE>

         requirements of the 1933 Act and rules and regulations promulgated
         thereunder and include all financial statements required by the SEC to
         be filed therewith, and use commercially reasonable efforts to cause
         such Registration Statement to become effective and remain effective in
         accordance with Section 2 hereof;

                  (b) prepare and file with the SEC such amendments and
         post-effective amendments to each Registration Statement as may be
         necessary to keep such Registration Statement effective for the
         applicable period and cause each Prospectus to be supplemented by any
         required prospectus supplement and, as so supplemented, to be filed
         pursuant to Rule 424 under the 1933 Act; and keep each Prospectus
         current during the period described under Section 4(3) and Rule 174
         under the 1933 Act that is applicable to transactions by brokers or
         dealers with respect to the Transfer Restricted Securities or Exchange
         Securities;

                  (c) in the case of a Shelf Registration, furnish to each
         Holder of Transfer Restricted Securities, to counsel for the Initial
         Purchasers and to counsel for the Holders and to each Underwriter of an
         Underwritten Offering of Transfer Restricted Securities, if any,
         without charge, as many copies of each Prospectus, including each
         preliminary Prospectus and any amendment or supplement thereto and such
         other documents as such Holder or Underwriter may reasonably request,
         in order to facilitate the public sale or other disposition of the
         Transfer Restricted Securities; and, subject to Section 3(i), the
         Company consents to the use of such Prospectus and any amendment or
         supplement thereto in accordance with applicable law by each of the
         selling Holders of Transfer Restricted Securities and any such
         Underwriters in connection with the offering and sale of the Transfer
         Restricted Securities covered by and in the manner described in such
         Prospectus or any amendment or supplement thereto in accordance with
         applicable law;

                  (d) use its commercially reasonable efforts to register or
         qualify the Transfer Restricted Securities under all applicable state
         securities or blue sky laws of such jurisdictions as any Holder of
         Transfer Restricted Securities covered by a Registration Statement
         shall reasonably request in writing by the time the applicable
         Registration Statement is declared effective by the SEC, and to
         cooperate with such Holders in connection with any filings required to
         be made with the National Association of Securities Dealers, Inc. and
         do any and all other acts and things which may be reasonably necessary
         or advisable to enable such Holder to consummate the disposition in
         each such jurisdiction of such Transfer Restricted Securities owned by
         such Holder; provided, however, that the Company shall not be required
         to (i) qualify as a foreign corporation or as a dealer in

                                       13

<PAGE>

         securities in any jurisdiction where it would not otherwise be required
         to qualify but for this Section 3(d), (ii) file any general consent to
         service of process or (iii) subject itself to taxation in any such
         jurisdiction if it is not so subject;

                  (e) in the case of a Shelf Registration, notify each Holder of
         Transfer Restricted Securities, counsel for the Holders and counsel for
         the Initial Purchasers (or, if applicable, separate counsel for the
         Holders) promptly and, if requested by any such Holder or counsel,
         confirm such advice in writing, (i) when a Registration Statement has
         become effective and when any post-effective amendment thereto has been
         filed and becomes effective, (ii) of any request by the SEC or any
         state securities authority for amendments and supplements to a
         Registration Statement and Prospectus or for additional information
         after the Registration Statement has become effective, (iii) of the
         issuance by the SEC or any state securities authority of any stop order
         suspending the effectiveness of a Registration Statement or the
         initiation of any proceedings for that purpose, (iv) if, between the
         effective date of a Registration Statement and the closing of any sale
         of Transfer Restricted Securities covered thereby, the Company receives
         any notification with respect to the suspension of the qualification of
         the Transfer Restricted Securities for sale in any jurisdiction or the
         initiation of any proceeding for such purpose, (v) of the happening of
         any event during the period a Shelf Registration Statement is effective
         which makes any statement made in such Shelf Registration Statement or
         the related Prospectus untrue in any material respect or which requires
         the making of any changes in such Registration Statement or Prospectus
         in order to make the statements therein not misleading, (vi) of any
         determination by the Company that a post-effective amendment to a
         Registration Statement would be appropriate and (vii) of any Suspension
         Period;

                  (f) use its commercially reasonable efforts to obtain the
         withdrawal of any order suspending the effectiveness of a Registration
         Statement at the earliest possible moment and provide immediate notice
         to each Holder of the withdrawal of any such order;

                  (g) in the case of a Shelf Registration, furnish to each
         Holder of Transfer Restricted Securities, without charge, at least one
         conformed copy of each Registration Statement and any post-effective
         amendment thereto (without documents incorporated therein by reference
         or exhibits thereto, unless requested);

                  (h) in the case of a Shelf Registration, cooperate with the
         selling Holders of Transfer Restricted Securities to facilitate the
         timely preparation

                                       14

         and delivery of certificates representing Transfer Restricted
         Securities (if such Securities are certificated) to be sold and not
         bearing any restrictive legends (unless required by applicable
         securities laws) and enable such Transfer Restricted Securities to be
         in such denominations (consistent with the provisions of the Indenture)
         and registered in such names as the selling Holders may reasonably
         request at least two Business Days prior to the closing of any sale of
         Transfer Restricted Securities;

                  (i) in the case of a Shelf Registration, upon the occurrence
         of any event contemplated by Section 3(e)(v) or (vii) hereof, use its
         commercially reasonable efforts to prepare and file with the SEC a
         supplement or post-effective amendment to a Registration Statement or
         the related Prospectus or any document incorporated therein by
         reference or file any other required document so that, as thereafter
         delivered to the purchasers of the Transfer Restricted Securities, such
         Prospectus will not contain any untrue statement of a material fact or
         omit to state a material fact necessary to make the statements therein,
         in the light of the circumstances under which they were made, not
         misleading. The Company agrees to notify the Holders to suspend use of
         the Prospectus as promptly as practicable after the occurrence of such
         an event, and the Holders hereby agree to suspend use of the Prospectus
         until the Company has amended or supplemented the Prospectus to correct
         such misstatement or omission and has furnished copies of the amended
         or supplemented Prospectus to the Holders or until the Company notifies
         the Holders that the sale of the Transfer Restricted Securities may be
         resumed;

                  (j) a reasonable time prior to the filing of any Registration
         Statement, any Prospectus, any amendment to a Registration Statement or
         amendment or supplement to a Prospectus (except any amendment or
         supplement solely to add additional selling securityholders), provide
         copies of such document to the Initial Purchasers and their counsel
         (and, in the case of a Shelf Registration Statement, the Holders and
         their counsel) and make such of the representatives of the Company as
         shall be reasonably requested by the Initial Purchasers or their
         counsel (and, in the case of a Shelf Registration Statement, the
         Holders or their counsel) available for discussion of such document,
         and shall not at any time file or make any amendment to the Shelf
         Registration Statement, any Prospectus or any amendment of or
         supplement to a Shelf Registration Statement or a Prospectus (except
         any amendment or supplement solely to add additional selling
         securityholders) of which the Initial Purchasers and their counsel
         (and, in the case of a Shelf Registration Statement, the Holders or
         their counsel) shall not have previously been advised and furnished a
         copy or to which the Initial Purchasers or their counsel (and, in the
         case of a Shelf

         object;

                  (k) obtain a CUSIP number for all Exchange Securities or
         Transfer Restricted Securities, as the case may be, not later than the
         effective date of the applicable Registration Statement;

                  (l) cause the Indenture to be qualified under the Trust
         Indenture Act of 1939, as amended (the "TIA"), in connection with the
         registration of the Exchange Securities or Transfer Restricted
         Securities, as the case may be, and cooperate with the Trustee and the
         Holders to effect such changes to the Indenture as may be required for
         the Indenture to be so qualified in accordance with the terms of the
         TIA and execute, and use commercially reasonable best efforts to cause
         the Trustee to execute, all documents as may be required to effect such
         changes and all other forms and documents required to be filed with the
         SEC to enable the Indenture to be so qualified in a timely manner;

                  (m) in the case of a Shelf Registration, make available for
         inspection by a representative of the Holders of the Transfer
         Restricted Securities, any Underwriter participating in any disposition
         pursuant to such Shelf Registration Statement, and attorneys and
         accountants designated by the Holders, at reasonable times and in a
         reasonable manner, all financial and other records, pertinent documents
         and properties of the Company, and cause the respective officers,
         directors and employees of the Company to supply all information
         reasonably requested by any such representative, Underwriter, attorney
         or accountant in connection with a Shelf Registration Statement, in
         each case that would customarily be reviewed or examined in connection
         with "due diligence" review of the Company;

                  (n) use its reasonable best efforts to cause the Exchange
         Securities to continue to be rated by two nationally recognized
         statistical rating organizations (as such term is defined in Rule
         436(g)(2) under the 1933 Act), if the Transfer Restricted Securities
         have been rated;

                  (o) if reasonably requested by any Holder of Transfer
         Restricted Securities covered by a Registration Statement, (i) promptly
         incorporate in a Prospectus supplement or post-effective amendment such
         information with respect to such Holder as such Holder reasonably
         requests to be included therein and (ii) make all required filings of
         such Prospectus supplement or such post-effective amendment as soon as
         reasonably practicable after the Company has received notification of
         the matters to be incorporated in such filing; and

                                       16

<PAGE>

                  (p) in the case of a Shelf Registration, enter into such
         customary agreements and take all such other actions in connection
         therewith (including those reasonably requested by the Holders of a
         majority of the Transfer Restricted Securities being sold thereunder)
         in order to expedite or facilitate the disposition of such Transfer
         Restricted Securities thereunder including, but not limited to,
         pursuant to an Underwritten Offering and in such connection, (i) to the
         extent possible, make such representations and warranties to the
         Holders and any Underwriters of such Transfer Restricted Securities
         with respect to the business of the Company and its subsidiaries, the
         Registration Statement, Prospectus and documents incorporated by
         reference or deemed incorporated by reference, if any, in each case, in
         form, substance and scope as are customarily made by issuers to
         underwriters in underwritten offerings and confirm the same if and when
         requested, (ii) obtain opinions of counsel to the Company (which
         counsel and opinions, in form, scope and substance, shall be reasonably
         satisfactory to the Holders of a majority in principal amount of the
         Transfer Restricted Securities being sold under such Shelf Registration
         Statement, such Underwriters and their respective counsel) addressed to
         each selling Holder and Underwriter of Transfer Restricted Securities,
         covering the matters customarily covered in opinions requested in
         underwritten offerings, (iii) obtain "cold comfort" letters from the
         independent certified public accountants of the Company (and, if
         necessary, any other certified public accountant of any subsidiary of
         the Company, or of any business acquired by the Company for which
         financial statements and financial data are or are required to be
         included in the Registration Statement) addressed to each selling
         Holder and Underwriter of Transfer Restricted Securities, such letters
         to be in customary form and covering matters of the type customarily
         covered in "cold comfort" letters in connection with underwritten
         offerings, and (iv) deliver such documents and certificates as may be
         reasonably requested by the Holders of a majority in principal amount
         of the Transfer Restricted Securities being sold under such Shelf
         Registration Statement or by the Underwriters, and which are
         customarily delivered in underwritten offerings, to evidence the
         continued validity of the representations and warranties of the Company
         made pursuant to clause (i) above and to evidence compliance with any
         customary conditions contained in an underwriting agreement.

                  In the case of a Shelf Registration Statement, the Company may
         require each Holder of Transfer Restricted Securities to furnish to the
         Company such information regarding the Holder and the proposed
         distribution by such Holder of such Transfer Restricted

                                       17

<PAGE>

         Securities as the Company may from time to time reasonably request in
         writing. No Holder of Transfer Restricted Securities may include its
         Transfer Restricted Securities in such Shelf Registration Statement
         unless and until such Holder furnishes such information to the Company.
         Each Holder including Transfer Restricted Securities in a Shelf
         Registration Statement shall agree to furnish promptly to the Company
         all information regarding such Holder and the proposed distribution by
         such Holder of such Transfer Restricted Securities required to make the
         information previously furnished to the Company by such Holder not
         materially misleading.

                  In connection with an Exchange Offer Registration, each Holder
         exchanging Securities for Exchange Securities shall be required to
         represent that (i) the Exchange Securities are being obtained in the
         ordinary course of business of the Person receiving such Exchange
         Securities, whether or not such Person is a Holder, (ii) neither such
         Holder nor any such other Person has an arrangement or understanding
         with any Person to participate in the distribution of Exchange
         Securities, (iii) other than as set forth in Section 4, if the Holder
         is not a broker-dealer, or is a broker-dealer but will not receive
         Exchange Securities for its own account in exchange for Securities,
         neither the Holder nor any such other Person is engaged in or intends
         to participate in a distribution of the Exchange Securities and (iv)
         neither the Holder nor any such other Person is an "affiliate" of the
         Company within the meaning of Rule 405 under the Securities Act or, if
         such Person is an "affiliate", that such Holder will comply with the
         registration and prospectus delivery requirements of the Securities Act
         to the extent applicable.

                  In the case of a Shelf Registration Statement, each Holder
         agrees that, upon receipt of any notice from the Company of the
         happening of any event of the kind described in Section 3(e)(v) hereof
         or of a Suspension Period, such Holder will forthwith discontinue
         disposition of Transfer Restricted Securities pursuant to a
         Registration Statement until such Holder's receipt of the copies of the
         supplemented or amended Prospectus contemplated by Section 3(i) hereof,
         and, if so directed by the Company, such Holder will destroy or deliver
         to the Company (at its expense) all copies in its possession, other
         than permanent file copies then in such Holder's possession, of the
         Prospectus covering such Transfer Restricted Securities current at the
         time of receipt of such notice.

                  If the Company shall give any such notice to suspend the
         disposition of Transfer Restricted Securities pursuant to a
         Registration Statement, the Company shall extend the period during
         which the Registration Statement shall be maintained effective pursuant
         to this Agreement by the number of days during the period from and
         including the date of the giving of such notice to and including the
         date when the

                                       18

<PAGE>

         Holders shall have received copies of the supplemented or amended
         Prospectus necessary to resume such dispositions.

                  The Holders of Transfer Restricted Securities covered by a
         Shelf Registration Statement who desire to do so may sell such Transfer
         Restricted Securities in an Underwritten Offering. In any such
         Underwritten Offering, the investment banker or investment bankers and
         manager or managers (the "Underwriters") that will administer the
         offering will be selected by the Majority Holders of the Transfer
         Restricted Securities included in such offering, provided that such
         Underwriters shall be reasonably acceptable to the Company.

         4.    Participation of Broker-Dealers in Exchange Offer.

                  (a) The parties hereto understand that the Staff of the SEC
         has taken the position that any broker-dealer that receives Exchange
         Securities for its own account in the Exchange Offer in exchange for
         Securities that were acquired by such broker-dealer as a result of
         market-making or other trading activities (a "Participating
         Broker-Dealer"), may be deemed to be an "underwriter" within the
         meaning of the 1933 Act and must deliver a prospectus meeting the
         requirements of the 1933 Act in connection with any resale of such
         Exchange Securities.

                  The Company understands that it is currently the Staff's
         position that if the Prospectus contained in the Exchange Offer
         Registration Statement includes a plan of distribution containing a
         statement to the above effect and the means by which Participating
         Broker-Dealers may resell the Exchange Securities, without naming the
         Participating Broker-Dealers or specifying the amount of Exchange
         Securities owned by them, such Prospectus may be delivered by
         Participating Broker-Dealers to satisfy their prospectus delivery
         obligation under the 1933 Act in connection with resales of Exchange
         Securities for their own accounts, so long as the Prospectus otherwise
         meets the requirements of the 1933 Act.

                  (b) In light of the above, notwithstanding the other
         provisions of this Agreement, the Company agrees that the provisions of
         this Agreement as they relate to a Shelf Registration shall also apply
         to an Exchange Offer Registration to the extent, and with such
         reasonable modifications thereto as may be, reasonably requested by the
         Initial Purchasers or by one or more Participating Broker-Dealers, in
         each case as provided in clause (ii) below, in order to expedite or
         facilitate the disposition of any Exchange Securities by Participating
         Broker-Dealers consistent with the positions of the Staff recited in
         Section 4(a) above; provided that:

                                       19

<PAGE>

                           (i)      the Company shall not be required to amend
                  or supplement the Prospectus contained in the Exchange Offer
                  Registration Statement, as would otherwise be contemplated by
                  Section 3(i), for a period exceeding 180 days after the last
                  Exchange Date (as such period may be extended pursuant to the
                  penultimate paragraph of Section 3 of this Agreement) and
                  Participating Broker-Dealers shall not be authorized by the
                  Company to deliver and shall not deliver such Prospectus after
                  such period in connection with the resales contemplated by
                  this Section 4; and

                           (ii)     the application of the Shelf Registration
                  procedures set forth in Section 3 of this Agreement to an
                  Exchange Offer Registration, to the extent not required by the
                  positions of the Staff of the SEC or the 1933 Act and the
                  rules and regulations thereunder, will be in conformity with
                  the reasonable request in writing to the Company by the
                  Initial Purchasers or with the reasonable request in writing
                  to the Company by one or more broker-dealers who certify to
                  the Initial Purchasers and the Company in writing that they
                  anticipate that they will be Participating Broker-Dealers; and
                  provided further that, in connection with such application of
                  the Shelf Registration procedures set forth in Section 3 to an
                  Exchange Offer Registration, the Company shall be obligated
                  (x) to deal only with one entity representing the
                  Participating Broker-Dealers, which shall be Lehman Brothers
                  Inc. unless it elects not to act as such representative, (y)
                  to pay the fees and expenses of only one counsel representing
                  the Participating Broker-Dealers, which shall be counsel to
                  the Initial Purchasers unless such counsel elects not to so
                  act and (z) to cause to be delivered only one, if any, "cold
                  comfort" letter with respect to the Prospectus in the form
                  existing on the last Exchange Date and with respect to each
                  subsequent amendment or supplement, if any, effected during
                  the period specified in clause (i) above.

                  (c) The Initial Purchasers shall have no liability to the
         Company, other than as Holders in accordance with the terms hereof, or
         to any other Holder with respect to any request that they may make
         pursuant to Section 4(b) above.

         5.    Indemnification and Contribution.

                  (a) The Company agrees to indemnify and hold harmless the
         Initial Purchasers, each Holder and each Person, if any, who controls
         the

                                       20

<PAGE>

         Initial Purchasers or any Holder within the meaning of either Section
         15 of the 1933 Act or Section 20 of the 1934 Act, or is under common
         control with, or is controlled by, the Initial Purchasers or any Holder
         (each, a "Participant"), from and against all losses, claims, damages
         and liabilities (including, without limitation, any legal fees or other
         expenses reasonably incurred by a Participant in connection with
         defending or investigating any such action or claim) caused by any
         untrue statement or alleged untrue statement of a material fact
         contained in any Registration Statement (or any amendment thereto)
         pursuant to which Exchange Securities or Transfer Restricted Securities
         were registered under the 1933 Act, including all documents
         incorporated therein by reference, or caused by any omission or alleged
         omission to state therein a material fact required to be stated therein
         or necessary to make the statements therein not misleading, or caused
         by any untrue statement or alleged untrue statement of a material fact
         contained in any Prospectus (as amended or supplemented if the Company
         shall have furnished any amendments or supplements thereto) forming a
         part of such Registration Statement, or caused by any omission or
         alleged omission to state therein a material fact necessary to make the
         statements therein in light of the circumstances under which they were
         made not misleading, except insofar as such losses, claims, damages or
         liabilities are caused by any such untrue statement or omission or
         alleged untrue statement or omission based upon and in conformity with
         information relating to the Initial Purchasers or any Holder furnished
         to the Company in writing by the Initial Purchasers or any selling
         Holder expressly for use therein; provided that the foregoing indemnity
         with respect to any Prospectus shall not inure to the benefit of any
         Holder from whom the Person asserting any such losses, claims, damages
         or liabilities purchased Securities, or any Person controlling such
         Holder, if a copy of the final Prospectus (as then amended or
         supplemented if the Company shall have furnished any amendments or
         supplements thereto) was not sent by, or delivered on behalf of, such
         Holder to such Person at or prior to the written confirmation of the
         sale of the Securities to such Person, if the final Prospectus (as so
         amended or supplemented) would have cured the defect giving rise to
         such loss, claim, damage or liability. In connection with any
         Underwritten Offering permitted by Section 3, the Company will also
         enter into an underwriting agreement pursuant to which the Company will
         agree to indemnify the Underwriters, if any, selling brokers, dealers
         and similar securities industry professionals participating in such
         Underwritten Offering, their officers and directors and each Person who
         controls such Persons (within the meaning of either Section 15 of the
         1933 Act or Section 20 of the 1934 Act) to the same extent as provided
         above with respect to the indemnification of the Holders, if requested
         in connection with any Registration Statement for such Underwritten
         Offering.

                                       21

<PAGE>

                  (b) Each Holder agrees, severally and not jointly, to
         indemnify and hold harmless the Company, the Initial Purchasers and the
         other selling Holders, and each of their respective directors and
         officers who sign the Registration Statement and each Person, if any,
         who controls the Company, the Initial Purchasers and any other selling
         Holder within the meaning of either Section 15 of the 1933 Act or
         Section 20 of the 1934 Act to the same extent as the foregoing
         indemnity from the Company to the Initial Purchasers and the Holders
         pursuant to Section 5(a), but only with reference to information
         relating to such Holder furnished to the Company in writing by such
         Holder expressly for use in any Registration Statement (or any
         amendment thereto) or any Prospectus (or any amendment or supplement
         thereto).

                  (c) In case any proceeding (including any governmental
         investigation) shall be instituted involving any Person in respect of
         which indemnity may be sought pursuant to either paragraph (a) or
         paragraph (b) above, such Person (the "INDEMNIFIED PARTY") shall
         promptly notify the Person against whom such indemnity may be sought
         (the "INDEMNIFYING PARTY") in writing, but the failure to so promptly
         notify the Indemnifying Party shall not negate the obligation to so
         indemnify such Indemnified Party unless the Indemnifying Party is
         materially prejudiced by such delay, and the Indemnifying Party, upon
         request of the Indemnified Party, shall retain counsel reasonably
         satisfactory to the Indemnified Party to represent the Indemnified
         Party and any others the Indemnifying Party may designate in such
         proceeding and shall pay the fees and expenses of such counsel related
         to such proceeding. In any such proceeding, any Indemnified Party shall
         have the right to retain its own counsel, but the fees and expenses of
         such counsel shall be at the expense of such Indemnified Party unless
         (i) the Indemnifying Party and the Indemnified Party shall have
         mutually agreed to the retention of such counsel or (ii) the named
         parties to any such proceeding (including any impleaded parties)
         include both the Indemnifying Party and the Indemnified Party and, in
         the opinion of counsel to the Indemnifying Party, representation of
         both parties by the same counsel would be inappropriate due to actual
         or potential differing interests between them. It is understood that
         the Indemnifying Party shall not, in connection with any proceeding or
         related proceedings in the same jurisdiction, be liable for (a) the
         fees and expenses of more than one separate firm (in addition to any
         local counsel) for the Initial Purchasers and all Persons, if any, who
         control the Initial Purchasers within the meaning of either Section 15
         of the 1933 Act or Section 20 of the 1934 Act, (b) the fees and
         expenses of more than one separate firm (in addition to any local
         counsel) for the Company, its directors, its officers who sign the
         Registration Statement and each Person, if any, who controls the
         Company within the meaning of either such Section and (c) the fees and

                                       22

<PAGE>

         expenses of more than one separate firm (in addition to any local
         counsel) for all Holders and all Persons, if any, who control any
         Holders within the meaning of either such Section, and that all such
         fees and expenses shall be reimbursed as they are incurred. In such
         case involving the Initial Purchasers and Persons who control the
         Initial Purchasers, such firm shall be designated in writing by the
         Initial Purchasers. In such case involving the Holders and such Persons
         who control Holders, such firm shall be designated in writing by the
         Majority Holders. In all other cases, such firm shall be designated by
         the Company. The Indemnifying Party shall not be liable for any
         settlement of any proceeding effected without its written consent but,
         if settled with such consent or if there be a final judgment for the
         plaintiff, the Indemnifying Party agrees to indemnify the Indemnified
         Party from and against any loss or liability by reason of such
         settlement or judgment. No Indemnifying Party shall, without the prior
         written consent of the Indemnified Party, effect any settlement of any
         pending or threatened proceeding in respect of which such Indemnified
         Party is or could have been a party and indemnity could have been
         sought hereunder by such Indemnified Party, unless such settlement
         includes an unconditional release of such Indemnified Party from all
         liability on claims that are the subject matter of such proceeding.

                  (d) If the indemnification provided for in paragraph (a) or
         paragraph (b) of this Section 5 is unavailable to an Indemnified Party
         or insufficient in respect of any losses, claims, damages or
         liabilities, then each Indemnifying Party under such paragraph, in lieu
         of indemnifying such Indemnified Party thereunder, shall contribute to
         the amount paid or payable by such Indemnified Party as a result of
         such losses, claims, damages or liabilities in such proportion as is
         appropriate to reflect the relative fault of the Indemnifying Party or
         parties on the one hand and of the Indemnified Party or parties on the
         other hand in connection with the statements or omissions that resulted
         in such losses, claims, damages or liabilities, as well as any other
         relevant equitable considerations. The relative fault of the Company
         and the Holders shall be determined by reference to, among other
         things, whether the untrue or alleged untrue statement of a material
         fact or the omission or alleged omission to state a material fact
         relates to information supplied by the Company or by the Holders and
         the parties' relative intent, knowledge, access to information and
         opportunity to correct or prevent such statement or omission. The
         Holders' respective obligations to contribute pursuant to this Section
         5(d) are several in proportion to the respective principal amount of
         Transfer Restricted Securities of the applicable Holder that were
         registered pursuant to a Registration Statement.

                                       23

<PAGE>

                  (e) The Company and each Holder agree that it would not be
         just or equitable if contribution pursuant to this Section 5(d) were
         determined by pro rata allocation or by any other method of allocation
         that does not take account of the equitable considerations referred to
         in Section 5(d) above. The amount paid or payable by an Indemnified
         Party as a result of the losses, claims, damages and liabilities
         referred to in Section 5(d) above shall be deemed to include, subject
         to the limitations set forth above, any legal or other expenses
         reasonably incurred by such Indemnified Party in connection with
         investigating or defending any such action or claim. Notwithstanding
         the provisions of this Section 5, no Holder shall be required to
         contribute any amount in excess of the amount by which the total price
         at which Transfer Restricted Securities were sold by such Holder
         exceeds the amount of any damages that such Holder has otherwise been
         required to pay by reason of such untrue or alleged untrue statement or
         omission or alleged omission. No Person guilty of fraudulent
         misrepresentation (within the meaning of Section 11(f) of the 1933 Act)
         shall be entitled to contribution from any Person who was not guilty of
         such fraudulent misrepresentation. The remedies provided for in this
         Section 5 are not exclusive and shall not limit any rights or remedies
         which may otherwise be available to any Indemnified Party at law or in
         equity.

                  The indemnity and contribution provisions contained in this
         Section 5 shall remain operative and in full force and effect
         regardless of (i) any termination of this Agreement, (ii) any
         investigation made by or on behalf of the Initial Purchasers, any
         Holder or any Person controlling the Initial Purchasers or any Holder,
         or by or on behalf of the Company, its officers or directors or any
         Person controlling the Company, (iii) acceptance of any of the Exchange
         Securities and (iv) any sale of Transfer Restricted Securities pursuant
         to a Shelf Registration Statement.

         6.    Miscellaneous.

                  (a) No Inconsistent Agreements. The Company has not entered
         into, and on or after the date of this Agreement will not enter into,
         any agreement which is inconsistent with the rights granted to the
         Holders of Transfer Restricted Securities in this Agreement or
         otherwise conflicts with the provisions hereof. The rights granted to
         the Holders hereunder do not in any way conflict with and are not
         inconsistent with the rights granted to the holders of the Company's
         other issued and outstanding securities under any such agreements.

                  (b) Amendments and Waivers. The provisions of this Agreement,
         including the provisions of this sentence, may not be amended, modified
         or supplemented, and waivers or consents to departures from the
         provisions

                                       24

<PAGE>

         hereof may not be given unless the Company has obtained the written
         consent of Holders of at least a majority in aggregate principal amount
         of the outstanding Transfer Restricted Securities affected by such
         amendment, modification, supplement, waiver or consent; provided,
         however, that no amendment, modification, supplement, waiver or consent
         to any departure from the provisions of Section 5 hereof or this
         paragraph (b) shall be effective as against any Holder of Transfer
         Restricted Securities unless consented to in writing by such Holder.

                  (c) Notices. All notices and other communications provided for
         or permitted hereunder shall be made in writing by hand-delivery,
         registered first-class mail, facsimile or any courier guaranteeing
         overnight delivery (i) if to a Holder, at the most current address
         given by such Holder to the Company by means of a notice given in
