The Notes may have notations, legends or endorsements required by law,

in the form of one or more permanent global notes with the global securities

                                       28

<PAGE>

such other custodian as the Depositary may direct), and registered in the name
of the Depositary or a 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 records of the Trustee and the Depositary
or its nominee as hereinafter provided.

         (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 2.2. 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.

                                       29
<PAGE>

         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 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 2.3. 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

                                       30

<PAGE>

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 2.4. 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 2.5. 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 2.6. 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

                                       31

<PAGE>

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.

                  (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
substantially the following form:

                  (ii)     The Person requesting the transfer or exchange must
         deliver or cause to be delivered to the Trustee a duly completed
         Regulation S Certificate; 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.

                  (iii)    The Person requesting the transfer or exchange must

         Certificate or (y) a duly completed Regulation S 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 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 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
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

                                       36

<PAGE>

         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 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

                                       37

<PAGE>

         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 2.7.  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

                                       38

<PAGE>

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 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 2.8.  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 2.9.  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

                                       39

<PAGE>

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.

         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

                                       40

<PAGE>

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 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 3.1.   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

                                       41

<PAGE>

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 3.2.   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 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 3.3.   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:

                                       42

<PAGE>

                  (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 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

                                       43

<PAGE>

of its covenants hereunder (as to which the Trustee is entitled to rely
exclusively on Officer's Certificates).

         SECTION 3.4.   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).

         SECTION 3.5.   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 Maturity thereof; or

                                       44

<PAGE>

                  (iv)  make any Restricted Investment (all such payments and
other actions set forth in these clauses (i) through (iv) above being
collectively referred to as "RESTRICTED PAYMENTS"),

         unless, at the time of and after giving effect to such Restricted
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
available is not less than 1.75 to 1.0, such Restricted Payment, 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:

                           (A)      Available Cash Flow from Operations for the
                  fiscal year of the Company then most recently ended for which
                  internal financial statements are available, plus

                           (B)      100% of the aggregate net cash proceeds
                  received by the Company (including the fair market value of
                  any Permitted Business or assets used or useful in a Permitted
                  Business to the extent acquired in consideration of Equity
                  Interests (other than Disqualified Stock) of the Company)
                  after the date of the Indenture as a contribution to its
                  common equity capital or from the issue or sale of Equity
                  Interests of the Company (other than Disqualified Stock) or
                  from the issue or sale of convertible or exchangeable
                  Disqualified Stock or convertible or exchangeable debt
                  securities of the Company that have been converted into or
                  exchanged for such Equity Interests (other than Equity
                  Interests (or Disqualified Stock or debt securities) sold to a
                  Subsidiary of the Company), plus

                           (C)      to the extent that any Restricted Investment
                  that was made after the date of the Indenture is sold for cash
                  or Cash Equivalents or otherwise liquidated or repaid for
                  cash, the lesser of (i) the cash return of capital with
                  respect to such Restricted Investment, including without
                  limitation repayment of principal of any Restricted Investment
                  constituting a loan or advance (less the cost of disposition,
                  if any) and (ii) the initial amount of such Restricted
                  Investment, plus

                           (D)      to the extent that any Unrestricted
                  Subsidiary of the Company is redesignated as a Restricted
                  Subsidiary after the date of

                  the Indenture, the lesser of (i) the fair market value of the
                  Company's Investment in such Subsidiary as of the date of such
                  redesignation or (ii) such fair market value as of the date on
                  which such Subsidiary was originally designated as an
                  Unrestricted Subsidiary (the amount determined at any time
                  pursuant to items (b), (c) and (d) being referred to as the
                  "INCREMENTAL FUNDS"); minus

                           (E)      the aggregate amount of Restricted Payments
                  previously made in reliance on Incremental Funds pursuant to
                  this clause (1) or clause (2) below; or

                  (2)   if 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, such Restricted
         Payment, together with the aggregate amount of all other Restricted
         Payments made by the Company and its Restricted Subsidiaries during the
         period commencing on the date such internal financial statements are
         available and ending on the date the next quarterly internal financial
         statements are available (such Restricted Payments for purposes of this
         clause (2) meaning only distributions on the Company's common stock and
         loans and advances to Williams and its Subsidiaries), is less than the
         sum, without duplication, of:

                           (A)      $50.0 million less the aggregate amount of
                  all Restricted Payments made by the Company pursuant to this
                  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
                  of the Indenture; plus

                           (B)      the aggregate amount of Incremental Funds at
                  such time 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

         of the Company in exchange for, or out of the net cash proceeds of, the
         substantially concurrent (a) contribution (other than from a Subsidiary
         of the Company) to the equity capital of the Company 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
         from an incurrence of Permitted Refinancing Indebtedness;

                  (iv)     the payment of any distribution or dividend by a
         Restricted Subsidiary of the Company or to the holders of such
         Restricted Subsidiary's Equity Interests on a pro rata basis;

                  (v)      so long as no Default or Event of Default has
         occurred and is continuing or would be caused thereby, dividends,
         distributions or advances to Williams Group Affiliates, at times and in
         amounts equal to 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

                                       47

<PAGE>

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 3.6.   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, 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;

                                       48

<PAGE>

                  (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:

                           (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);

                                       49

<PAGE>

                  (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:

                  (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

                                       50

<PAGE>

         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 3.7.   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 3.8.   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 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,

                                       51

<PAGE>

         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);

                  (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;

                                       52

<PAGE>

                  (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 3.9.   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
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:

                  (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

                                       54

<PAGE>

         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

                  (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

                                       55

<PAGE>

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 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

                                       56

<PAGE>

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:

                  (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;

                                       57

<PAGE>

                  (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 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

                                       58

<PAGE>

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

                         CONSOLIDATION, MERGER AND SALE

         SECTION 4.1.   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 this clause (iv) shall no longer be applicable
         from and after any Investment Grade Date.

                                       60

<PAGE>

         (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 4.2.   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.

         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

                                       61

<PAGE>

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 4.3.   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.

                              DEFAULTS AND REMEDIES

         SECTION 5.1.   Events of Default.  (a) Each of the following is an
Event of Default:

<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

                                       63

<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

                                       64

<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 5.2.   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.

                                       65

<PAGE>

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

         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 5.3.   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 5.4.   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

                                       66

<PAGE>

Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

         SECTION 5.5.   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 5.6.   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 5.7.   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

                                       67

<PAGE>

unconditional and shall not be impaired or affected without the consent of such
Holder.

         SECTION 5.8.   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 5.9.   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:

                                       68

<PAGE>

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

         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 6.1.   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

                                       69

<PAGE>

                  (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 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 6.2.   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.

                                       70

<PAGE>

         (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.

         (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,

                                       71

<PAGE>

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, 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 6.3.   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 6.4.   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 6.5.   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 6.6.   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

                                       72

<PAGE>

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 6.7.   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

                                       73

<PAGE>

(ix) hereof occurs, the expenses and the compensation for the services are
intended to constitute expenses of administration under any Bankruptcy Law.

         SECTION 6.8.   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.

         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,

                                       74

<PAGE>

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

                                       75

<PAGE>

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.

                  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;

<PAGE>

                  (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

will survive. After satisfying the conditions in clauses (a)(i)(B), (ii), (iii)
and (iv), only the Company's obligations in Article II and Sections 3.01, 3.02,

will acknowledge in writing the discharge of the Company's obligations under the
Notes and the Indenture other than the surviving obligations.

Guarantee will terminate ("LEGAL 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 (a) the
         Company has received from, or there has been published by, the Internal
         Revenue Service a ruling or (b) since the date of the Indenture, there
         has been a change in the applicable federal income tax law, in either
         case to the effect that, and based thereon such Opinion of Counsel will
         confirm that, the Holders of the outstanding 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;

                                       77

<PAGE>

                  (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;

         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.

         Prior to the end of the 91-day period, none of the Company's
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 7.3.   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

         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;

                                       78

<PAGE>

                  (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);

                  (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;

         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.

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

         SECTION 7.4.   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 7.5.   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

                                       79

<PAGE>

payment of principal of, premium, if any, Liquidated Damages, if any, and
interest on the Notes.

         SECTION 7.6.   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
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 7.7.   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.

         SECTION 8.1.   Without Consent of Holders. The Company, the Guarantors
and the Trustee may amend or supplement the Indenture or any of the Notes or

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

         in place of certificated Notes;

                  (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 8.2.   With Consent of Holders.

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
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);

                                       82

<PAGE>

                  (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);

                  (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 8.3.   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 8.4.   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.

                                       83

<PAGE>

         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.

         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 8.5.   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 8.6.   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.

<PAGE>

                                   REDEMPTION

         SECTION 9.1.   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 9.2.   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:

                  (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 9.3.   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:

                                       85

<PAGE>

                  (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;

                  (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 9.4.   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 9.5.   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

                                       86

<PAGE>

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 9.6.   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 9.7.   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
plus accrued and unpaid interest to the redemption date.

         and

                  (ii)     at least 65% of the aggregate principal amount of
         Notes remains outstanding immediately after the occurrence of such

extent applicable, pursuant to the provisions of Sections 9.01 through 9.06.

                  (vi)     a Holder may tender all or any portion of its Notes,
         subject to the requirement that any portion of a Note tendered must be
         in a multiple of $1,000 principal amount;

                  (vii)    the place or places where Notes are to be surrendered

         requires, duly endorsed or accompanied by a duly executed written
         instrument of transfer);

                  (ix)     interest on any Note not tendered will continue to
         accrue;

                  (x)      on the Change of Control Payment Date the purchase
         price will become due and payable on each Note accepted for purchase,

         (e)      The Company will comply with Rule 14e-1 under the Exchange Act

                                   GUARANTIES

         SECTION 10.1.  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

                                       90

<PAGE>

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 10.2.  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;

                  (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 10.3.  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,

                                       91

<PAGE>

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 10.4.  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 10.5.  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
such payment so long as any amount payable by the Company hereunder or under the
Notes remains unpaid.

         SECTION 10.6.  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 10.7.  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 10.8.  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

                                       92

<PAGE>

authentication constitutes due delivery of the Subsidiary Guarantee set forth in
the Indenture on behalf of each Guarantor.

         SECTION 10.9.  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.

                 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

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.
Capitalized terms used but not defined in this Note have the respective meanings
given to such terms in the Indenture.

among other things, to furnish appropriate endorsements and transfer documents
and to pay any taxes and fees required by law or permitted by the Indenture. The
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
outstanding Notes, and compliance in a particular instance by the Company with
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
with the terms of the Indenture. Without the consent of any Holder, the Company
and the Trustee may amend or supplement the Indenture or the Notes (i) to cure
any ambiguity, omission, defect or inconsistency; (ii) to provide for the
assumption of the Company's obligations to Holders of Notes in the case of a
merger, consolidation or sale of all or substantially all of the assets of the
Company; (iii) to provide for uncertificated Notes in addition to or in place of
certificated Notes; (iv) to provide for any Guarantee of the Notes, to secure

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
or alter the provisions (including, without limitation, the amount of any
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

<PAGE>

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, 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.

Committee on Uniform Note Identification Procedures, the Company has caused

Notes. No representation is made as to the accuracy of such numbers as printed
on the Notes and reliance may be placed only on the other identification numbers
printed thereon.

tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

         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.

Restricted Notes. In addition to the rights provided to Holders of Notes under
