         THIS THIRD SUPPLEMENTAL INDENTURE, dated as of November 16, 2001,
between Weatherford International, Inc., a Delaware corporation (the "Company"),
and The Bank of New York (as successor in interest to Bank of Montreal Trust
Company) (the "Trustee").

                             RECITALS OF THE COMPANY

         WHEREAS, the Company has heretofore executed and delivered to the
Trustee an Indenture, dated as of May 17, 1996, as supplemented by the First
Supplemental Indenture thereto, dated as of May 27, 1998, and the Second
Supplemental Indenture thereto, dated as of June 30, 2000 (the "Indenture"),
providing for the issuance from time to time of one or more series of the
Company's Securities; and

         WHEREAS, Section 901(7) of the Indenture provides that the Company and
the Trustee may from time to time enter into one or more indentures supplemental
thereto to establish the form or terms of Securities of a new series; and

         WHEREAS, Section 901(5) of the Indenture permits the execution of
supplemental indentures without the consent of any Holders to add to, change or
eliminate any provisions of the Indenture in respect of one or more series of
Securities; provided, that any such change or elimination does not adversely
affect in any material respect any outstanding Security of any series created
prior to the execution of such supplemental indenture; and

         WHEREAS, Sections 201 and 301 of the Indenture provide that the Company
may enter into supplemental indentures to establish the terms and provisions of
a series of Securities issued pursuant to the Indenture; and

         WHEREAS, the Company desires to issue 6 5/8% Senior Notes due 2011,
Series A, and, in connection with the Exchange Offer (as hereinafter defined)
pursuant to the Registration Rights Agreement (as hereinafter defined), 6 5/8%
Senior Notes due 2011, Series B (collectively, the "Notes"), a new series of
Security, the issuance of which was authorized by or pursuant to resolutions of
the Board of Directors of the Company; and

         WHEREAS, the Company, pursuant to the foregoing authority, proposes in
and by this Third Supplemental Indenture to supplement and amend in certain
respects the Indenture insofar as it will apply only to the Notes (and not to
any other series); and

         WHEREAS, all things necessary have been done to make the Notes, when
executed by the Company and authenticated and delivered hereunder and duly
issued by the Company, the valid obligations of the Company, and to make this
Third Supplemental Indenture a valid agreement of the Company, in accordance
with their and its terms.

         NOW THEREFORE:

         In consideration of the premises provided for herein, the Company and
the Trustee mutually covenant and agree for the equal and proportionate benefit
of all Holders of the Notes as follows:

<PAGE>

                                   ARTICLE ONE

                                    THE NOTES

Section 101 Designation of Notes; Establishment of Form.

         There shall be a series of Securities designated "6 5/8% Senior Notes
due 2011, Series A" and "6 5/8% Senior Notes due 2011, Series B" of the Company,
which together shall constitute a single series of Securities under the
Indenture, and the form thereof shall be substantially as set forth in Annex A
hereto, which is incorporated into and shall be deemed a part of this Third
Supplemental Indenture, in each case with such appropriate insertions,
omissions, substitutions and other variations as are required or permitted by
the Indenture, and may have such letters, numbers or other marks of
identification and such legends or endorsements placed thereon as may be
required to comply with the rules of any securities exchange or as may,
consistently herewith, be determined by the officers of the Company executing
such Notes, as evidenced by their execution of the Notes.

            (a) Restricted Global Securities. Series A Notes offered and sold in
reliance on Rule 144A to qualified institutional buyers as defined in Rule 144A
(collectively, "QIBs" or individually a "QIB") or in reliance on Regulation S
shall be issued initially in the form of one or more Restricted Global
Securities, which shall be deposited on behalf of the purchasers of the Series A
Notes represented thereby with the Trustee, at its Corporate Trust Office, as
security custodian ("Security Custodian") for the depositary, The Depository
Trust Company ("DTC"), and registered in the name of its nominee, Cede & Co.,
duly executed by the Company and authenticated by the Trustee as hereinafter
provided. The Depositary shall be a clearing agency registered under the U.S.
Securities Exchange Act of 1934, as amended (the "Exchange Act"). Each
Restricted Global Security in global form, to the extent that it represents the
interests of Non-U.S. Persons, will be held by Cede & Co. for the accounts of
designated agents on behalf of the Euroclear System ("Euroclear") and
Clearstream Banking, societe anonyme ("Clearstream"). Interests in a Global
Security acquired through an offshore transaction in reliance on Regulation S
may be held only through Euroclear or Clearstream during the 40 day restricted
period required under Regulation S. The aggregate principal amount of a
Restricted Global Security may from time to time be increased or decreased by
adjustments made on the records of the Security Custodian as hereinafter
provided, subject in each case to compliance with the Applicable Procedures.

            (b) Global Securities in General. Each Global Security shall
represent such of the outstanding Notes as shall be specified therein and each
shall provide that it shall represent the aggregate amount of outstanding Notes
from time to time endorsed thereon and that the aggregate amount of outstanding
Notes represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges or redemptions of such Notes. Any endorsement
of a Global Security to reflect the amount of any increase or decrease in the
principal amount of the Notes represented thereby shall be made by the Security
Custodian in accordance with the standing instructions and procedures existing
between the Depositary and the Security Custodian.

                                      -2-

                  Members of, or participants in, the Depositary ("Agent
Members") shall have no rights under this Indenture with respect to any Global
Security held on their behalf by the Depositary or under the Global Security,
and the Depositary (including, for this purpose, its nominee) may be treated by
the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner and Holder of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall (A) 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 (B) impair, as between the Depositary and its Agent Members, the operation of
customary practices governing the exercise of the rights of a Holder of any
Note.

                  Any Global Security may be endorsed with or have incorporated
in the text thereof such legends or recitals or changes not inconsistent with
the provisions of this Indenture as may be required by the Security Custodian,
the Depositary or by the National Association of Securities Dealers, Inc. in
order for such Securities to be tradable on any market developed for trading of
securities pursuant to Rule 144A or Regulation S or required to comply with any
applicable law or any regulation thereunder or with the rules and regulations of
any securities exchange or automated quotation system upon which the Securities
may be listed or traded or to conform with any usage with respect thereto, or to
indicate any special limitations or restrictions to which any particular
Securities are subject.

                  (c) Certificated Securities. Certificated Securities shall be
issued only under the limited circumstances provided in Section 102(a)(1)
hereof.

         The Company initially appoints DTC to act as Depositary with respect to
the Global Securities.

         The Company initially appoints the Trustee to act as Paying Agent and
Security Registrar with respect to the Notes.

Section 102 Transfer and Exchange.

                  (a) Transfer and Exchange of Global Securities.

                      (1) Certificated Securities shall be issued in exchange
         for interests in the Global Securities only if (x) the Depositary
         notifies the Company that it is unwilling or unable to continue as
         depositary for the Global Securities or if it at any time ceases to be
         a "clearing agency" registered under the Exchange Act if so required by
         applicable law or regulation and a successor depositary is not
         appointed by the Company within 90 days, (y) an Event of Default has
         occurred and is continuing or (z) the Company determines in its sole
         discretion that Certificated Securities shall be issued in exchange for
         interests in the Global Securities. In either case, the Company shall
         execute, and the Trustee shall, upon receipt of a Company Order (which
         the Company agrees to deliver promptly), authenticate and deliver
         Certificated Securities in an aggregate principal amount equal to the
         principal amount of such Global Securities in exchange therefor. Only
         Restricted Certificated Securities shall be issued in exchange for
         beneficial interests in Restricted Global Securities, and only
         Unrestricted Certificated Securities shall be

                                      -3-
<PAGE>

         issued in exchange for beneficial interests in Unrestricted Global
         Securities. Certificated Securities issued in exchange for beneficial
         interests in Global Securities shall be registered in such names and
         shall be in such authorized denominations as the Depositary, pursuant
         to instructions from its direct or indirect participants or otherwise,
         shall instruct the Trustee. The Trustee shall deliver or cause to be
         delivered such Certificated Securities to the persons in whose names
         such Securities are so registered. Such exchange shall be effected in
         accordance with the Applicable Procedures. Nothing herein shall require
         the Trustee to communicate directly with beneficial owners, and the
         Trustee shall in connection with any transfers hereunder be entitled to
         rely on instructions received through the registered Holder.

                      (2) Notwithstanding any other provisions of this Indenture
         other than the provisions set forth in Section 102(a)(1) hereof, a
         Global Security 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.

                  (b) Transfer and Exchange of Certificated Securities. When
Certificated Securities are presented by a Holder to a Security Registrar with a
request:

                      (1) to register the transfer of the Certificated
         Securities to a person who will take delivery thereof in the form of
         Certificated Securities only; or

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

such Security Registrar shall register the transfer or make the exchange as
requested; provided, however, that the Certificated Securities presented or
surrendered for register of transfer or exchange:

                      (1) shall be duly endorsed or accompanied by a written
         instrument of transfer in accordance with the eighth paragraph of
         Section 305 of the Indenture; and

                      (2) in the case of a Restricted Certificated Security,
         such request shall be accompanied by the following additional
         information and documents, as applicable:

                         (A) if (i) such Restricted Certificated Security is
                  being delivered to the Security Registrar by a Holder for
                  registration in the name of such Holder, without transfer, or
                  (ii) such Restricted Certificated Security is being
                  transferred to the Company or a Subsidiary of the Company, or
                  (iii) such Restricted Certificated Security is being
                  transferred to a person the Holder reasonably believes is a
                  QIB in accordance with Rule 144A, or (iv) such Restricted
                  Certificated Security is being transferred pursuant to an
                  effective registration statement under the Securities Act, or
                  (v) pursuant to an exemption from the registration
                  requirements of the Securities Act to a Non-U.S. Person in an
                  offshore transaction in accordance with Regulation S, a
                  certification to that

                                      -4-
<PAGE>

                  effect from such Holder (in substantially the form set forth
                  in the Transfer Certificate (as defined in Section 102(e)(1)
                  hereof)); or

                         (B) if such Restricted Certificated Security is being
                  transferred pursuant to an exemption from the registration
                  requirements of the Securities Act in accordance with Rule
                  144, a certification to that effect from the Holder (in
                  substantially the form set forth in the Transfer Certificate),
                  and, if the Company or such Security Registrar so requests, a
                  customary opinion of counsel, certificates and other
                  information reasonably acceptable to the Company and such
                  Security Registrar to the effect that such transfer is in
                  compliance with the Securities Act.

                  (c) Transfer of a Beneficial Interest in a Restricted Global
Security for a Beneficial Interest in an Unrestricted Global Security. Any
person having a beneficial interest in a Restricted Global Security may upon
request, subject to the Applicable Procedures, transfer such beneficial interest
to a person who is required or permitted to take delivery thereof in the form of
an Unrestricted Global Security. Upon receipt by the Trustee of written
instructions or such other form of instructions as is customary for the
Depositary, from the Depositary or its nominee on behalf of any person having a
beneficial interest in a Restricted Global Security and the following additional
information and documents in such form as is customary for the Depositary from
the Depositary or its nominee on behalf of the person having such beneficial
interest in the Restricted Global Security (all of which may be submitted by
facsimile or electronically):

                      (1) if such beneficial interest is being transferred
         pursuant to an effective registration statement under the Securities
         Act, a certification to that effect from the transferor (in
         substantially the form set forth in the Transfer Certificate); or

                      (2) if such beneficial interest is being transferred
         pursuant to an exemption from the registration requirements of the
         Securities Act in accordance with Rule 144, a certification to that
         effect from the transferor (in substantially the form set forth in the
         Transfer Certificate) and, if the Company or the Trustee so requests,
         a customary opinion of counsel, certificates and other information
         reasonably acceptable to the Company and the Trustee to the effect that
         such transfer is in compliance with the Securities Act,

the Trustee, as a Security Registrar and Security Custodian, shall reduce or
cause to be reduced the aggregate principal amount of the Restricted Global
Security by the appropriate principal amount and shall increase or cause to be
increased the aggregate principal amount of the Unrestricted Global Security by
a like principal amount. Such transfer shall otherwise be effected in accordance
with the Applicable Procedures. If no Unrestricted Global Security is then
outstanding, the Company shall execute and the Trustee shall, upon receipt of a
Company Order (which the Company agrees to deliver promptly), authenticate and
deliver an Unrestricted Global Security.

                  (d) Transfers of Certificated Securities for Beneficial
Interest in Global Securities. If Certificated Securities are issued in exchange
for beneficial interests in Global Securities and, thereafter, the events or
conditions specified in Section 102(a)(1) hereof which

                                      -5-
<PAGE>

required such exchange shall have ceased to exist, the Company shall mail notice
to the Trustee and to the Holders stating that Holders may exchange Certificated
Securities for interests in Global Securities by complying with the procedures
set forth in this Indenture and briefly describing such procedures and the
events or circumstances requiring that such notice be given. Thereafter, if
Certificated Securities are presented by a Holder to a Security Registrar with a
request:

                  (1) to register the transfer of such Certificated Securities
         to a person who will take delivery thereof in the form of a beneficial
         interest in a Global Security, which request shall specify whether such
         Global Security will be a Restricted Global Security or an Unrestricted
         Global Security; or

                  (2) to exchange such Certificated Securities for an equal
         principal amount of beneficial interests in a Global Security, which
         beneficial interests will be owned by the Holder transferring such
         Certificated Securities (provided that in the case of such an exchange,
         Restricted Certificated Securities may be exchanged only for Restricted
         Global Securities and Unrestricted Certificated Securities may be
         exchanged only for Unrestricted Global Securities),

the Security Registrar shall register the transfer or make the exchange as
requested by canceling such Certificated Security and causing, or directing the
Security Custodian to cause, the aggregate principal amount of the applicable
Global Security to be increased accordingly and, if no such Global Security is
then outstanding, the Company shall issue and the Trustee shall authenticate and

         The Company may redeem the Notes, at its option, in whole or in part,
at any time or from time to time prior to their maturity at the "make-whole"
redemption price equal to the greater of:

         (1)      100% of the principal amount of the Notes to be redeemed, and

         (2)      as determined by the Quotation Agent, the sum of the present
                  values of the remaining scheduled payments of principal and
                  interest on the Notes to be redeemed (not including any
                  portion of the payments of interest accrued as of the date of
                  redemption) discounted to the Redemption Date on a semi-annual
                  basis (assuming a 360-day year consisting of twelve 30-day
                  months) at the Adjusted Treasury Rate plus 25 basis points,

plus accrued interest thereon and Liquidated Damages, if any, with respect
thereto, to the Redemption Date.

         The Company shall not be required to make sinking fund payments with
respect to the Notes.

NOTICE OF REDEMPTION

         Notice of redemption will be mailed by first-class mail at least 30

Notes to be redeemed at its registered address. Notes in denominations larger
than $1,000 may be redeemed in part, but only in whole multiples of $1,000.

denominations of $1,000 and any integral multiple thereof. As provided in the

this Note is registrable in the Security Register, upon surrender of this Note
for registration or transfer at the office or agency in a place of payment for
Notes, duly endorsed by, or accompanied by a written instrument of transfer in

the Holder hereof or his attorney duly authorized in writing, and thereupon one
or more new Notes, of any authorized denominations and for the same aggregate
principal amount, executed by the Company and authenticated and delivered by the
Trustee, will be issued to the designated transferee or transferees.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Note for registration of transfer, the

notice to the contrary.

on the Notes or an Event of Default in respect of certain covenants or
provisions in the Indenture which may not be modified without the consent of the
Holder of each Note as described below) by the Holders of at least a majority in

provide for or facilitate the administration of the trusts thereunder by more
than one Trustee, pursuant to the requirements of Section 611(b) of the
Indenture; or to cure any ambiguity, omission, defect or inconsistency.

         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 fixed in accordance with the terms of the Indenture.

         Without the consent of each Holder affected, the Company may not (i)

of or interest on, the Notes, or reduce the principal amount thereof or the rate
of interest thereon or any premium payable upon the redemption thereof, (ii)

required for any such supplemental indenture, or the consent of whose Holders is
required for

                                      A-8
<PAGE>

any waiver (of compliance with certain provisions of the Indenture or certain
defaults thereunder and their consequences) provided for in the Indenture, (vii)
reduce the requirements of Section 1404 of the Indenture for quorum or voting,
(viii) change any obligation of the Company to maintain an office or agency in
the places and for the purposes specified in Section 1002 of the Indenture, or
(ix) or modify any of the provisions of Sections 513, 902 or 1008 of the
Indenture, except to increase any such percentage or to provide that certain
other provisions of the Indenture cannot be modified or waived without the
consent of the Holder of each Outstanding Security affected thereby.

SUCCESSOR PERSON

         When a successor person assumes all the obligations of its predecessor
under the Notes and the Indenture in accordance with the terms and conditions of
the Indenture, the predecessor person will (except in certain circumstances
specified in the Indenture) be released from those obligations.

DEFAULTS AND REMEDIES

         Events of Default are defined in the Indenture and generally include:
(i) default by the Company in the payment of any interest upon or Liquidated
Damages with respect to any Note when it becomes due and payable, and
continuation of such default for a period of 30 days; (ii) default in the
payment of the principal of (or premium, if any, on) any Note at its Maturity;
(iii) default by the Company in the performance, or breach, of its other
covenants or agreements in, or provisions of, the Notes or in the Indenture
which shall not have been remedied within 90 days after written notice by the
Trustee or by the holders of at least 25% in principal amount of the Notes then
outstanding (or, in the event that other Securities issued under the Indenture
are also affected by the default, then 25% in principal amount of all
outstanding Securities so affected); (iv) certain events involving bankruptcy,
insolvency or reorganization of the Company; or (v) the acceleration of the
maturity of any indebtedness for borrowed money of the Company or any Subsidiary
(other than the Notes or Non-Recourse Indebtedness) having an aggregate of more
than $25,000,000 in principal amount outstanding. If an Event of Default occurs
with respect to the Notes and is continuing, then the Trustee or the Holders of
not less than 25% in principal amount of the then outstanding Notes (or, in the
case of an Event of Default described in clause (iii) above, if outstanding
Securities of other series are affected by such Default, then at least 25% in
principal amount of the then outstanding Securities so affected) may declare the
principal of, accrued interest on and Liquidated Damages, if any, with respect
to all of the Notes to be due and payable immediately, by a notice in writing to
the Company (and to the Trustee if given by the Holders of the Notes), and upon
any such declaration such principal amount shall become immediately due and
payable. If an Event of Default described in clause (iv) above occurs, the
principal of, accrued interest on and Liquidated Damages, if any, with respect
to all the Notes will become immediately due and payable without any declaration
or other act on the part of the Trustee or any of the Holders of the Notes.
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 (or all
affected Securities) may direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Holders notice of any continuing default
(except a

                                      A-9
<PAGE>

default in payment of principal or interest) if it determines that withholding
notice is in their interests. The Company must furnish an annual compliance
certificate to the Trustee.

DISCHARGE PRIOR TO MATURITY

         The Indenture with respect to the Notes shall be discharged and
canceled upon the payment of all of the Notes and shall be discharged except for
certain obligations upon the irrevocable deposit with the Trustee of funds or
U.S. Government Obligations sufficient for such payment.

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.

AUTHENTICATION

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

INDENTURE TO CONTROL; GOVERNING LAW

         In the case of any conflict between the provisions of this Note and the
Indenture, the provisions of the Indenture shall control.

         THE INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO
APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THE LAWS OF ANOTHER
JURISDICTION WOULD BE REQUIRED THEREBY.

ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL SECURITIES AND RESTRICTED
CERTIFICATED SECURITIES; LIQUIDATED DAMAGES

         In addition to the rights provided to Holders of Notes under the
Indenture, Holders of Restricted Global Securities and Restricted Certificated
Securities shall have all the rights set forth in the Registration Rights
Agreement applicable to the Notes, including payment of Liquidated Damages, if
any. The Company promises to pay Liquidated Damages, if any, payable pursuant to
Section 5 of the Registration Rights Agreement with respect to Transfer
Restricted Securities, semi-annually on each Interest Payment Date, to the
persons who are registered Holders of Notes at the close of business on the May
1 or November 1 next preceding the Interest Payment Date, even if such Notes are
cancelled after such record date and on or before such Interest Payment Date,
except as provided in Section 307 of the Indenture with respect to defaulted
interest. All obligations of the Company to pay Liquidated Damages, if any,
payable pursuant to Section 5 of the Registration Rights Agreement that are
outstanding with

                                      A-10
<PAGE>

respect to any Transfer Restricted Security at the time such security ceases to
be a Transfer Restricted Security shall survive until such time as all such
payment obligations with respect to such security shall have been satisfied in
full. Each Holder of a Transfer Restricted Security, by his acceptance thereof,
acknowledges and agrees to the provisions of such Registration Rights Agreement,
including without limitation the obligations of the Holders with respect to a
registration and the indemnification of the Company to the extent provided
therein.

CUSIP NUMBERS

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

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

<PAGE>

                  (b) Holders of Transfer Restricted Securities. A Person is
deemed to be a holder of Transfer Restricted Securities (each, a "Holder")
whenever such Person owns Transfer Restricted Securities.

         3. REGISTERED EXCHANGE OFFER.

                  (a) Unless the Exchange Offer shall not be permissible under
applicable law or Commission policy (after the procedures set forth in Section
6(a) below have been complied with), the Company shall use (i) its reasonable
best efforts to cause to be filed with the Commission as soon as practicable
after the Closing Date, but in no event later than 90 days after the Closing
Date, a Registration Statement under the Securities Act relating to the Exchange
Notes and the Exchange Offer, (ii) its reasonable best efforts to cause such
Registration Statement to be declared effective on or prior to 180 days after
the Closing Date, (iii) in connection with the foregoing, file (A) all
pre-effective amendments to such Registration Statement as may be necessary in
order to cause such Registration Statement to become effective, (B) if
applicable, a post-effective amendment to such Registration Statement pursuant
to Rule 430A under the Securities Act and (C) cause all necessary filings in
connection with the registration and qualification of the Exchange Notes to be
made under the blue sky laws of such jurisdictions as are necessary to permit
Consummation of the Exchange Offer and (iv) on or promptly after the
effectiveness of such Registration Statement, commence the Exchange Offer. The
Exchange Offer shall be on the appropriate form permitting registration of the
Exchange Notes to be offered in exchange for the Notes and to permit resales of
Exchange Notes held by Broker-Dealers as contemplated by Section 3(c) below.

                  (b) The Company shall use its reasonable best efforts to cause
the Exchange Offer Registration Statement to be effective continuously and shall
keep the Exchange Offer open for a period of not less than the minimum period
required under applicable U.S. Federal and state securities laws to Consummate
the Exchange Offer; provided, however, that in no event shall such period be
less than 20 business days. The Company shall cause the Exchange Offer to comply
with all applicable U.S. federal and state securities laws. No securities other
than the Exchange Notes shall be included in the Exchange Offer Registration
Statement. The Company shall use its reasonable best efforts to cause the
Exchange Offer to be Consummated on the earliest practicable date after the
Exchange Offer Registration Statement has become effective, but in any event on
or prior to the 210th day after the Closing Date.

                  (c) The Company shall indicate in a "Plan of Distribution"
section of the Prospectus contained in the Exchange Offer Registration Statement
that any Broker-Dealer who holds Notes that are Transfer Restricted Securities
and that were acquired for its own account as a result of market-making
activities or other trading activities (other than Transfer Restricted
Securities acquired directly from the Company) may exchange such Notes pursuant
to the Exchange Offer; however, such Broker-Dealer may be deemed to be an
"underwriter" within the meaning of the Securities Act and must, therefore,
deliver a Prospectus meeting the requirements of the Securities Act in
connection with any resales of the Exchange Notes received by such Broker-Dealer
in the Exchange Offer, which Prospectus delivery requirement may be satisfied by
the delivery by such Broker-Dealer of the Prospectus contained in the Exchange
Offer Registration Statement. Such "Plan of Distribution" section shall also
contain all other

                                      -4-
<PAGE>

information with respect to such resales by Broker-Dealers that the Commission
may require in order to permit such resales pursuant thereto, but such "Plan of
Distribution" shall not name any such Broker-Dealer or disclose the amount of
Notes held by any such Broker-Dealer except to the extent required by the
Commission.

                  The Company shall use its reasonable best efforts to keep the
Exchange Offer Registration Statement continuously effective, supplemented and
amended as required by the provisions of Section 6(c) below to the extent
necessary to ensure that it is available for resales of Exchange Notes acquired
by Broker-Dealers for their own accounts as a result of market-making activities
or other trading activities, and to ensure that it conforms with the
requirements of this Agreement, the Securities Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period of at
least 90 days after the Consummation of the Exchange Offer.

                  The Company shall provide sufficient copies of the latest
version of such Prospectus to Broker-Dealers promptly upon request at any time
during such 90-day period in order to facilitate such resales.

         4. SHELF REGISTRATION.

                  (a) Shelf Registration. If (i) the Company is not required to
file an Exchange Offer Registration Statement or to Consummate the Exchange
Offer because the Exchange Offer is not permitted by applicable U.S. law or
Commission policy (after the procedures set forth in Section 6(a) below have
been complied with) or (ii) if any Holder of Transfer Restricted Securities
shall notify the Company prior to the 20th day following the Consummation of the
Exchange Offer that such Holder (A) is prohibited by applicable U.S. law or
Commission policy from participating in the Exchange Offer, (B) may not resell
the Exchange Notes acquired by it in the Exchange Offer to the public without
delivering a prospectus and that the Prospectus contained in the Exchange Offer
Registration Statement is not appropriate or available for such resales by such
Holder or (C) is a Broker-Dealer and holds Notes acquired directly from the
Company or one of its affiliates, then the Company shall:

                  (x) use its reasonable best efforts to cause to be filed a
         Registration Statement pursuant to Rule 415 under the Securities Act,
         which may be an amendment to the Exchange Offer Registration Statement
         if permitted by the rules and regulations of the Commission (in either
         event, the "Shelf Registration Statement") on or prior to the earliest
         to occur of (1) the 60th day after the date on which the Company
         determines that it is not permitted to file the Exchange Offer
         Registration Statement, or permitted to Consummate the Exchange Offer
         and (2) the 60th day after the date on which the Company receives
         notice from a Holder of Transfer Restricted Securities as contemplated
         by clause (ii) of paragraph (a) above (such earliest date being the
         "Shelf Filing Deadline"), which Shelf Registration Statement shall
         provide for resales of all Transfer Restricted Securities by the
         Holders which shall have provided the information required pursuant to
         Section 4(b) hereof; and

                                      -5-
<PAGE>

                  (y) use its reasonable best efforts to cause such Shelf
         Registration Statement to be declared effective by the Commission on or
         before the later of the 90th day after the Shelf Filing Deadline and
         the 180th day after the Closing Date.

Subject to Section 5(b), the Company shall use its reasonable best efforts to
keep such Shelf Registration Statement continuously effective, supplemented and
amended as required by the provisions of Sections 6(b) and (c) hereof to the
extent necessary to ensure that it is available for resales of Notes or Exchange
Notes by the Holders of Transfer Restricted Securities entitled to the benefit
of this Section 4(a), and to ensure that it conforms with the requirements of
this Agreement, the Securities Act and the policies, rules and regulations of
the Commission as announced from time to time, for a period of at least two
years following the Closing Date or such shorter period that will terminate when
all Notes or Exchange Notes covered by the Shelf Registration Statement have
been sold pursuant to the Shelf Registration Statement.

                  (b) Provision by Holders of Certain Information in Connection
with the Shelf Registration Statement. No Holder of Transfer Restricted
Securities may include any of its Transfer Restricted Securities in any Shelf
Registration Statement pursuant to this Agreement unless and until such Holder
furnishes to the Company in writing, within 20 days after receipt of a request
therefor, such information as the Company may reasonably request for use in
connection with any Shelf Registration Statement or Prospectus or preliminary
Prospectus included therein. No Holder of Transfer Restricted Securities shall
be entitled to Liquidated Damages pursuant to Section 5 hereof unless and until
such Holder shall have timely provided all such reasonably requested information
as set forth in the preceding sentence. Each Holder as to which any Shelf
Registration Statement is being effected agrees to furnish promptly to the
Company all information required to be disclosed in order to make the
information previously furnished to the Company by such Holder not materially
misleading.

         5. LIQUIDATED DAMAGES.

                  (a) If (i) any of the Registration Statements required by this
Agreement are not filed with the Commission on or prior to the date specified
for such filing in Sections 3(a) and 4(a), as applicable, (ii) any of such
required Registration Statements have not been declared effective by the
Commission on or prior to the date specified for such effectiveness in Sections
3(a) and 4(a), as applicable, (iii) the Exchange Offer has not been Consummated
within 210 days after the Closing Date, or longer if required by applicable U.S.
Federal and state securities laws, with respect to the Exchange Offer
Registration Statement or (iv) any Registration Statement required by this
Agreement is filed and declared effective but shall thereafter cease to be
effective or fail to be usable in connection with resales of Transfer Restricted
Securities during the time periods such Registration Statement is required to
remain effective pursuant to the terms hereof without being succeeded
immediately by a post-effective amendment to such Registration Statement that
cures such failure and that is itself immediately declared effective (except as
permitted in paragraph (b); such period of time during which any such
Registration Statement is not effective or any such Registration Statement or
the related Prospectus is not usable being referred to as a "Blackout Period")
(each such event referred to in clauses (i) through (iv), a "Registration
Default"), the Company agrees to pay liquidated damages ("Liquidated Damages"),
which shall accrue to each Holder of Transfer Restricted Securities

                                      -6-
<PAGE>

adversely affected by such Registration Default from and during the continuance
of the Registration Default, in an amount equal to 0.25% per year of the
principal amount of Transfer Restricted Securities held by such Holder with
respect to the first 90-day period immediately following the occurrence of such
Registration Default. The amount of Liquidated Damages shall increase by an
additional 0.25% per year of the principal amount of Transfer Restricted
Securities with respect to each subsequent 90-day period (or portion thereof)
until all Registration Defaults have been cured, up to a maximum amount of
Liquidated Damages of .50% of the principal amount of Transfer Restricted
Securities. The Company shall in no event be required to pay Liquidated Damages
for more than one Registration Default at any given time. All accrued Liquidated
Damages shall be paid to Record Holders by the Company in the same manner and at
the same time(s) as interest is paid under the Notes. Following the cure of all
Registration Defaults relating to any particular Transfer Restricted Securities,
the accrual of Liquidated Damages with respect to such Transfer Restricted
Securities will cease.

                  (b) A Registration Default referred to in Section 5(a)(iv)
shall be deemed not to have occurred and be continuing in relation to a
Registration Statement or the related Prospectus if (i) the Blackout Period has
occurred solely as a result of (x) the filing of a post-effective amendment to
such Shelf Registration Statement to incorporate annual audited financial
information with respect to the Company where such post-effective amendment is
not yet effective and needs to be declared effective to permit Holders to use
the related Prospectus or (y) the occurrence of other material events with
respect to the Company that would need to be described in such Registration
Statement or the related Prospectus and (ii) in the case of clause (y), the
Company is proceeding promptly and in good faith to amend or supplement
(including by way of filing documents under the Exchange Act which are
incorporated by reference into the Registration Statement) such Registration
Statement and the related Prospectus to describe such events; provided, however,
that in any case if such Blackout Period occurs for a continuous period in
excess of 30 days, a Registration Default shall be deemed to have occurred on
the 31st day of such Blackout Period and Liquidated Damages shall be payable in
accordance with the above paragraph from the day such Registration Default
occurs until such Registration Default is cured or until the Company is no
longer required pursuant to this Agreement to keep such Registration Statement
effective or such Registration Statement or the related Prospectus usable;
provided, further, that in no event shall the total of all Blackout Periods
exceed 45 days during the aggregate of any 12-month period.

                  All payment obligations of the Company set forth in this
section that are outstanding with respect to any Transfer Restricted Security at
the time such security ceases to be a Transfer Restricted Security shall survive
until such time as all such payment obligations with respect to such security
shall have been satisfied in full.

         6. REGISTRATION PROCEDURES.

                  (a) Exchange Offer Registration Statement. In connection with
the Exchange Offer, the Company shall comply with all of the provisions of
Section 6(c) below, shall use its reasonable best efforts to effect such
exchange to permit the sale of Transfer Restricted Securities being sold in
accordance with the intended method or methods of distribution thereof, and
shall comply with all of the following provisions:

                                      -7-
<PAGE>

                           (i) As a condition to its participation in the
         Exchange Offer pursuant to the terms of this Agreement, each Holder of
         Transfer Restricted Securities shall furnish, upon the request of the
         Company, prior to the Consummation thereof, a written representation to
         the Company (which may be contained in the letter of transmittal
         contemplated by the Exchange Offer Registration Statement) to the
         effect that (A) it is not an affiliate of the Company, (B) it is not
         engaged in, and does not intend to engage in, and has no arrangement or
         understanding with any Person to participate in, a distribution of the
         Exchange Notes to be issued in the Exchange Offer and (C) it is
         acquiring the Exchange Notes in its ordinary course of business. In
         addition, all such Holders of Transfer Restricted Securities shall
         otherwise cooperate in the Company's preparations for the Exchange
         Offer. Each Holder hereby acknowledges and agrees that any
         Broker-Dealer and any such Holder using the Exchange Offer to
         participate in a distribution of the securities to be acquired in the
         Exchange Offer (1) could not under Commission policy as in effect on
         the date of this Agreement rely on the position of the Commission
         enunciated in Exxon Capital Holdings Corporation (available May 13,
         1988) and Morgan Stanley and Co., Inc. (available June 5, 1991), as
         interpreted in the Commission's letter to Shearman & Sterling dated
         July 2, 1993, and similar no-action letters and (2) must comply with
         the registration and prospectus delivery requirements of the Securities
         Act in connection with a secondary resale transaction and that such a
         secondary resale transaction should be covered by an effective
         Registration Statement containing the selling security holder
         information required by Item 507 or 508, as applicable, of Regulation
         S-K if the resales are of Exchange Notes obtained by such Holder in
         exchange for Notes acquired by such Holder directly from the Company.

                           (ii) If requested by the Commission, prior to
         effectiveness of the Exchange Offer Registration Statement, the Company
         shall state to the Commission that the Company is registering the
         Exchange Offer in reliance on the position of the Commission enunciated
         in Exxon Capital Holdings Corporation (available May 13, 1988) and
         Morgan Stanley and Co., Inc. (available June 5, 1991) and shall
         represent to the Commission that the Company has not entered into any
         arrangement or understanding with any Person to distribute the Exchange
         Notes to be received in the Exchange Offer and that, to the best of the
         Company's information and belief, each Holder participating in the
         Exchange Offer is acquiring the Exchange Notes in its ordinary course
         of business and has no arrangement or understanding with any Person to
         participate in the distribution of the Exchange Notes received in the
         Exchange Offer; and

                           (iii) The Company shall use its reasonable best
         efforts to cause the Exchange Offer to be Consummated in accordance
         with the terms of this Agreement, and, upon such Consummation, the
         Company shall deliver to the registrar under the Indenture Exchange
         Notes in the same aggregate principal amount as the aggregate principal
         amount of Notes that were properly tendered by Holders thereof pursuant
         to the Exchange Offer.

                  (b) Shelf Registration Statement. In connection with the Shelf
Registration Statement, the Company shall comply with all the provisions of
Section 6(c) below and shall use

                                      -8-
<PAGE>

its reasonable best efforts to effect such registration in accordance with the
terms hereof to permit the sale of the Transfer Restricted Securities being sold
in accordance with the intended method or methods of distribution thereof, and
pursuant thereto the Company will as expeditiously as possible prepare and file
with the Commission a Registration Statement relating to the registration on any
appropriate form under the Securities Act, which form shall be available for the
sale of the Transfer Restricted Securities in accordance with the intended
method or methods of distribution thereof.

                  (c) General Provisions. In connection with any Registration
Statement and any Prospectus required by this Agreement to permit the sale or
resale of Transfer Restricted Securities (including, without limitation, any
Registration Statement and the related Prospectus required to permit resales of
Notes and Exchange Notes by Broker-Dealers), the Company shall:

                           (i) use its reasonable best efforts to keep such
         Registration Statement continuously effective and provide all requisite
         financial statements for the period specified in Sections 3 or 4 of
         this Agreement, as applicable; upon the occurrence of any event that
         would cause any such Registration Statement or the Prospectus contained
         therein (A) to contain a material misstatement or omission or (B) not
         to be effective and usable for resale of Transfer Restricted Securities
         during the period required by this Agreement, the Company shall file
         promptly an appropriate amendment to such Registration Statement, in
         the case of clause (A), correcting any such misstatement or omission,
         and, in the case of either clause (A) or (B), use its reasonable best
         efforts to cause such amendment to be declared effective and such
         Registration Statement and the related Prospectus to become usable for
         their intended purpose(s) as soon as practicable thereafter.
         Notwithstanding the foregoing, the Company may allow the Shelf
         Registration Statement to cease to become effective and usable if (x)
         the board of directors of the Company determines in good faith that it
         is in the best interests of the Company not to disclose the existence
         of or facts surrounding any proposed or pending material corporate
         transaction involving the Company, and the Company notifies the Holders
         within two business days after such board of directors makes such
         determination or (y) the Prospectus contained in the Shelf Registration
         Statement contains an untrue statement of a material fact or omits to
         state a material fact necessary in order to make the statements made
         therein, in the light of the circumstances under which they were made,
         not misleading; provided that Liquidated Damages shall accrue on the
         Notes as provided in Section 5 hereof;

                           (ii) prepare and file with the Commission such
         amendments and post-effective amendments to the Registration Statement
         as may be necessary to keep the Registration Statement effective for
         the applicable period set forth in Sections 3 or 4 hereof, as
         applicable; cause the Prospectus to be supplemented by any required
         Prospectus supplement, and as so supplemented to be filed pursuant to
         Rule 424 under the Securities Act, and to comply fully with the
         applicable provisions of Rules 424 and 430A under the Securities Act in
         a timely manner; and comply with the provisions of the Securities Act
         with respect to the disposition of all securities covered by such
         Registration Statement during the applicable period in accordance with
         the intended

                                      -9-
<PAGE>

         method or methods of distribution by the sellers thereof set forth in
         such Registration Statement or supplement to the Prospectus;

                           (iii) if any Transfer Restricted Securities shall be
         in certificated form, cooperate with the selling Holders of Transfer
         Restricted Securities and the underwriter(s), if any, to facilitate the
         timely preparation and delivery of certificates representing Transfer
         Restricted Securities to be sold and not bearing any restrictive
         legends; and enable such Transfer Restricted Securities to be in such
         denominations and registered in such names as the Holders or the
         underwriter(s), if any, may request at least two business days prior to
         any sale of Transfer Restricted Securities made by such underwriter(s);

                           (iv) use its reasonable best efforts to cause the
         Transfer Restricted Securities covered by the Registration Statement to
         be registered with or approved by such other governmental agencies or
         authorities as may be necessary to enable the seller or sellers thereof
         or the underwriter(s), if any, to consummate the disposition of such
         Transfer Restricted Securities, subject to the proviso contained in
         clause (c)(ix) below;

                           (v) if any fact or event contemplated by clause
         (d)(i)(D) below shall exist or have occurred, prepare a supplement or
         post-effective amendment to the Registration Statement or related
         Prospectus or any document incorporated therein by reference or file
         any other required document so that, as thereafter delivered to the
         purchasers of Transfer Restricted Securities, the Prospectus will not
         contain an untrue statement of a material fact or omit to state any
         material fact necessary to make the statements made therein, in the
         light of the circumstances under which they were made, not misleading;

                           (vi) provide a CUSIP, CINS or ISIN number, as
         applicable, for all Transfer Restricted Securities not later than the
         effective date of the Registration Statement and provide the Trustee
         under the Indenture with printed certificates for the Transfer
         Restricted Securities which are in a form eligible for deposit with the
         depositary;

                           (vii) cooperate and assist in any filings required to
         be made with the NASD and in the performance of any due diligence
         investigation by any underwriter (including any "qualified independent
         underwriter") that is required to be retained in accordance with the
         rules and regulations of the NASD;

                           (viii) otherwise use its best efforts to comply with
         all applicable rules and regulations of the Commission, and make
         generally available to its security holders, as soon as practicable, a
         consolidated earnings statement meeting the requirements of Rule 158
         (which need not be audited) for the twelve-month period (A) commencing
         at the end of any fiscal quarter in which Transfer Restricted
         Securities are sold to underwriters in a firm or best efforts
         Underwritten Offering or (B) if not sold to underwriters in such an
         offering, beginning with the first month of the Company's first fiscal
         quarter commencing after the effective date of the Registration
         Statement; and

                                      -10-
<PAGE>

                           (ix) cause the Indenture to be qualified under the
         TIA not later than the effective date of the first Registration
         Statement required by this Agreement, and, in connection therewith,
         cooperate with the Trustee and the Holders of Notes and Exchange Notes
         to effect such changes to the Indenture as may be required for such
         Indenture to be so qualified in accordance with the terms of the TIA;
         and execute, and use its reasonable best efforts to cause the Trustee
         to execute, all documents that may be required to effect such changes
         and all other forms and documents required to be filed with the
         Commission to enable such Indenture to be so qualified in a timely
         manner.

                  (d) Additional Provisions Applicable to Shelf Registration
Statements. In connection with each Shelf Registration Statement the Company
shall:

                           (i) advise the underwriter(s), if any, and selling
         Holders of Transfer Restricted Securities promptly and, if requested by
         such Persons, to confirm such advice in writing, (A) when the
         Prospectus or any Prospectus supplement or post-effective amendment has
         been filed, and, with respect to the Shelf Registration Statement or
         any post-effective amendment thereto, when the same has become
         effective, (B) of any request by the Commission for amendments to the
         Shelf Registration Statement or amendments or supplements to the
         Prospectus or for additional information relating thereto, (C) of the
         issuance by the Commission of any stop order suspending the
         effectiveness of the Registration Statement under the Securities Act,
         of the suspension by any state securities commission of the
         qualification of the Transfer Restricted Securities for offering or
         sale in any jurisdiction or of the initiation of any proceeding for any
         of the preceding purposes and (D) of the existence of any fact or the
         happening of any event that requires the making of any additions to or
         changes in the Shelf Registration Statement or the Prospectus in order
         that the Shelf Registration Statement and the Prospectus do not contain
         an untrue statement of a material fact or omit to state a material fact
         necessary to make the statements made therein, in the light of the
         circumstances under which they were made, not misleading. If at any
         time the Commission shall issue any stop order suspending the
         effectiveness of the Shelf Registration Statement, or any U.S. state
         securities commission or other regulatory authority shall issue an
         order suspending the qualification or exemption from qualification of
         the Transfer Restricted Securities under U.S. state securities or blue
         sky laws, the Company shall use its reasonable best efforts to obtain
         the withdrawal or lifting of such order at the earliest possible time;

                           (ii) if requested in writing, furnish to each of the
         selling Holders of Transfer Restricted Securities and each of the
         underwriter(s), if any, before filing with the Commission, copies of
         any Shelf Registration Statement or any Prospectus included therein or
         any amendments or supplements to any such Shelf Registration Statement
         or Prospectus, which documents will be subject to the review of such
         Holders and underwriter(s), if any, for a period of at least five
         business days, and the Company will not file any such Shelf
         Registration Statement or Prospectus or any amendment or supplement to
         any such Shelf Registration Statement or Prospectus if a selling Holder
         of Transfer Restricted Securities covered by such Shelf Registration
         Statement or the underwriter(s), if any, shall have reasonably objected
         to the filing thereof; such Holders

                                      -11-
<PAGE>

         and underwriter(s) shall be deemed to have reasonably objected to such
         filing if such Shelf Registration Statement, amendment, Prospectus or
         supplement, as applicable, as proposed to be filed, contains an untrue
         statement of a material fact or omits to state any material fact
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, or fails to
         comply with the applicable requirements of the Securities Act;

                           (iii) make available for inspection at reasonable
         times at each of the Company's principal places of business by the
         Holders of Transfer Restricted Securities, any underwriter
         participating in any disposition pursuant to such Shelf Registration
         Statement and any attorney or accountant retained by such selling
         Holders or any of the underwriter(s), who shall certify to the Company
         that they have a current intention to sell Transfer Restricted
         Securities pursuant to a Shelf Registration Statement, such relevant
         financial and other records, pertinent corporate documents and
         properties of the Company as reasonably requested and cause the
         Company's officers, directors and employees to respond to such
         inquiries as shall be reasonably necessary, in the reasonable judgment
         of counsel to such Holders, to conduct a reasonable investigation;
         provided, however, that the foregoing inspection and information
         gathering shall be coordinated on behalf of the selling Holders by one
         counsel designated by and on behalf of such Holders and, provided,
         further, that each such party shall be required to maintain in
         confidence and not disclose to any other Person any information or
         records reasonably designated by the Company in writing as being
         confidential, until such time as (A) such information becomes a matter
         of public record (whether by virtue of its inclusion in such Shelf
         Registration Statement or otherwise) or (B) such Person shall be
         required so to disclose such information pursuant to a subpoena or
         order of any court or other governmental agency or body having
         jurisdiction over the matter (subject to the requirements of such
         order, and only after such Person shall have given the Company prompt
         prior written notice of such requirement);

                           (iv) if requested by any selling Holders of Transfer
         Restricted Securities or the underwriter(s), if any, promptly
         incorporate in any Shelf Registration Statement or Prospectus pursuant
         to a supplement or post-effective amendment if necessary, such
         information as such selling Holders and underwriter(s), if any, may
         reasonably request to have included therein, including, without
         limitation, information relating to the "Plan of Distribution" of the
         Transfer Restricted Securities information with respect to the
         principal amount of Transfer Restricted Securities being sold to such
         underwriter(s), the purchase price being paid therefor and any other
         terms of the offering of the Transfer Restricted Securities to be sold
         in such offering; and make all required filings of such Prospectus
         supplement or post-effective amendment as soon as practicable after the
         Company is notified of the matters to be incorporated in such
         Prospectus supplement or post-effective amendment; provided, however,
         that the Company shall not be required to take any action pursuant to
         this Section 6(d)(iv) that would, in the opinion of counsel for the
         Company reasonably satisfactory to the Initial Purchasers, violate
         applicable law;

                                      -12-
<PAGE>

                           (v) deliver to each selling Holder of Transfer
         Restricted Securities and each of the underwriter(s), if any, without
         charge, as many copies of the Prospectus (including each preliminary
         Prospectus) and any amendment or supplement thereto as such Persons
         reasonably may request; the Company hereby consents to the use of the
         Prospectus and any amendment or supplement thereto by each of the
         selling Holders and each of the underwriter(s), if any, in connection
         with the offering and the sale of the Transfer Restricted Securities
         covered by the Prospectus or any amendment or supplement thereto;

                           (vi) furnish to each Holder whose Transfer Restricted
         Securities have been included in a Shelf Registration Statement in
         connection with such exchange or sale, without charge, at least one
         copy of the Registration Statement, as first filed with the Commission,
         and of each amendment thereto, including, upon request, all documents
         incorporated by reference therein and all exhibits (including exhibits
         incorporated therein by reference);

                           (vii) enter into an underwriting agreement on not
         more than one occasion in the case of an offering pursuant to a Shelf
         Registration, and make such representations and warranties, and take
         all such other actions in connection therewith in order to expedite or
         facilitate the disposition of the Transfer Restricted Securities
         pursuant to any Registration Statement contemplated by this Agreement,
         all to such extent as may be reasonably requested by any Holder or
         Holders of Transfer Restricted Securities who hold at least 25% in
         aggregate principal amount of such class of Transfer Restricted
         Securities; provided that the Company shall not be required to enter
         into any such agreement more than once with respect to all of the
         Transfer Restricted Securities and may delay entering into such
         agreement if the board of directors of the Company determines in good
         faith that it is in the best interests of the Company not to disclose
         the existence of or facts surrounding any proposed or pending material
         corporate transaction involving the Company; and whether or not an
         underwriting agreement is entered into and whether or not the
         registration is an Underwritten Registration, the Company shall, if
         requested, cause:

                                 (A) its counsel (including both staff counsel
         and outside counsel, with the overall coverage of such opinions
         allocated between them in a customary manner) to deliver opinions and
         updates thereof relating to the Transfer Restricted Securities in
         customary form addressed to such Holders and the managing underwriters,
         if any, thereof and dated, in the case of the initial opinions, the
         effective date of such Shelf Registration Statement (it being agreed
         that the matters to be covered by such opinions shall include, without
         limitation, the due incorporation and good standing of the Company and
         its significant subsidiaries; the qualification of the Company and its
         significant subsidiaries to transact business as foreign corporations;
         the due authorization, execution and delivery of any agreement
         (including, if requested, an underwriting agreement in customary form)
         executed in order to facilitate the disposition of the Transfer
         Restricted Securities pursuant to the Shelf Registration Statement; the
         due authorization, execution, authentication and issuance, and the
         validity and enforceability, of the applicable Transfer Restricted
         Securities; the absence of material legal or

                                      -13-
<PAGE>

         governmental proceedings involving the Company and its subsidiaries;
         the absence of governmental approvals required to be obtained in
         connection with the Shelf Registration Statement, the offering and sale
         of the applicable Transfer Restricted Securities, or any agreement
         (including, if requested, an underwriting agreement in customary form)
         executed in order to facilitate the disposition of the Transfer
         Restricted Securities pursuant to the Shelf Registration Statement; the
         compliance as to form of such Shelf Registration Statement and any
         documents incorporated by reference therein and of the Indenture with
         the requirements of the Securities Act and the TIA, respectively; and,
         as of the date of the opinion and as of the effective date of the Shelf
         Registration Statement or most recent post-effective amendment thereto,
         as the case may be, the absence from such Shelf Registration Statement
         and the prospectus included therein, as then amended or supplemented,
         and from any documents incorporated by reference therein of an untrue
         statement of a material fact or the omission to state therein a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading (in the case of any such documents,
         in the light of the circumstances existing at the time that such
         documents were filed with the Commission under the Exchange Act)):

                                 (B) its officers to executed and deliver all
         customary documents and certificates and updates thereof requested by
         any underwriters of the applicable Transfer Restricted Securities; and

                                 (C) its independent public accountants and the
         independent public accountants with respect to any other entity for
         which financial information is provided in the Shelf Registration
         Statement to provide to the selling Holders of the applicable Transfer
         Restricted Securities and any underwriter therefor a comfort letter in
         customary form and covering matters of the type customarily covered in
         comfort letters in connection with underwritten offerings, subject to
         receipt of appropriate documentation as contemplated, and only if
         permitted, by Statement of Auditing Standards No. 72; and

                           (viii) prior to any public offering of Transfer
         Restricted Securities cooperate with the selling Holders of Transfer
         Restricted Securities, the underwriter(s), if any, and their respective
         counsel in connection with the registration and qualification of the
         Transfer Restricted Securities under the securities or blue sky laws of
         such jurisdictions as the selling Holders of Transfer Restricted
         Securities or underwriter(s) may reasonably request and do any and all
         other acts or things necessary or advisable to enable the disposition
         in such jurisdictions of the Transfer Restricted Securities covered by
         the Shelf Registration Statement filed pursuant to Section 4 hereof;
         provided, however, that the Company shall not be obligated to qualify
         as a foreign corporation in any jurisdiction in which it is not now so
         qualified or to take any action that would subject it to general
         consent to service of process, other than as to matters and
         transactions relating to the Shelf Registration Statement, in any
         jurisdiction where it is not now so subject.

                  (e) Each Holder agrees by acquisition of a Transfer Restricted
Security that, upon receipt of any notice from the Company of the existence of
any fact of the kind described in

                                      -14-
<PAGE>

Section 6(d)(i) hereof, such Holder will forthwith discontinue disposition of
Transfer Restricted Securities pursuant to the Shelf Registration Statement
until such Holder's receipt of the copies of the supplemented or amended
Prospectus contemplated by Section 6(d)(v) hereof, or until it is advised in
writing (the "Advice") by the Company that the use of the Prospectus may be
resumed, and has received copies of any additional or supplemental filings that
are incorporated by reference in the Prospectus. If so directed by the Company,
each Holder will deliver to the Company (at the Company's expense) all copies,
other than permanent file copies then in such Holder's possession, of the
Prospectus covering such Transfer Restricted Securities that was current at the
time of receipt of such notice.

                  (f) The Company may require each Holder of Transfer Restricted
Securities as to which any registration is being effected to furnish to the
Company such information regarding such Holder and such Holder's intended method
of distribution of the applicable Transfer Restricted Securities as the Company
may from time to time reasonably request in writing, but only to the extent that
such information is required in order to comply with the Securities Act. Each
such Holder agrees to notify the Company as promptly as practicable of (i) any
inaccuracy or change in information previously furnished by such Holder to the
Company or (ii) the occurrence of any event, in either case, as a result of
which any Prospectus relating to such registration contains or would contain an
untrue statement of a material fact regarding such Holder or such Holder's
intended method of distribution of the applicable Transfer Restricted Securities
or omits to state any material fact regarding such Holder or such Holder's
intended method of distribution of the applicable Transfer Restricted Securities
required to be stated therein or necessary to make the statements made therein,
in light of the circumstances under which they were made, not misleading and
promptly to furnish to the Company any additional information required to
correct and update any previously furnished information or required so that such
Prospectus shall not contain, with respect to such Holder or the distribution of
the applicable Transfer Restricted Securities an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein not misleading.

         7. REGISTRATION EXPENSES.

                  (a) All expenses incident to the Company's performance of or
compliance with this Agreement will be borne by the Company regardless of
whether a Registration Statement becomes effective, including without limitation
and as applicable: (i) all Commission, securities exchange or NASD registration

Restricted Securities covered by the Shelf Registration Statement to act as

(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expenses of any annual
audit and the fees and expenses of any Person, including special experts,
retained by the Company.

                  (b) Each Holder of Transfer Restricted Securities will pay all
underwriting discounts, if any, and commissions and transfer taxes, if any,
relating to the disposition of such Holder's Transfer Restricted Securities.

         8. INDEMNIFICATION.

                  (a) The Company shall indemnify and hold harmless each Holder
of Transfer Restricted Securities, its officers and employees and each Person,
if any, who controls any such Holders, within the meaning of the Securities Act,
from and against any loss, claim, damage or liability, joint or several, or any
action in respect thereof (including, but not limited to, any loss, claim,
damage, liability or action relating to purchases, sales and registration of the
Notes and the Exchange Notes), to which that Holder, officer, employee or
controlling Person may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon (i) any untrue statement or alleged untrue statement of a material
fact contained (A) in any Registration Statement or preliminary Prospectus or
Prospectus or in any amendment or supplement thereto or (B) in any blue sky
application or other document prepared or executed by any Company (or based upon
any written information furnished by the Company) specifically for the purpose
of qualifying any or all of the Notes under the securities laws of any state or
other jurisdiction (any such application, document or information being
hereinafter called a "Blue Sky Application"); (ii) the omission or alleged
omission to state in any Registration Statement, preliminary Prospectus or
Prospectus, or in any amendment or supplement thereto, or in any Blue Sky
Application, any material fact required to

                                      -16-
<PAGE>

be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; or (iii) any act or
failure to act or any alleged act or failure to act by any Holder of Transfer
Restricted Securities in connection with, or relating in any manner to, the
Notes or the Exchange Notes or the offering contemplated by any Registration
Statement, and which is included as part of or referred to in any loss, claim,
damage, liability or action arising out of or based upon matters covered by
clause (i) or (ii) above (provided that the Company shall not be liable under
this clause (iii) to the extent that it is determined in a final judgment by a
court of competent jurisdiction that such loss, claim, damage, liability or
action resulted directly from any such acts or failures to act undertaken or
omitted to be taken by such Holder through its gross negligence or willful
misconduct); and shall reimburse each Holder and each such officer, employee or
controlling Person promptly upon demand for any legal or other expenses
reasonably incurred by that Holder, officer, employee or controlling Person in
connection with investigating or defending or preparing to defend against any
such loss, claim, damage, liability or action as such expenses are incurred;
provided, however, that the Company shall not be liable in any such case to the
extent that any such loss, claim, damage, liability or action arises out of, or
is based upon, any untrue statement or alleged untrue statement or omission or
alleged omission made in any Registration Statement, preliminary Prospectus or
Prospectus, or in any such amendment or supplement, or in any Blue Sky
Application, in reliance upon and in conformity with written information
concerning such Holder furnished to the Company by or on behalf of any Holder
specifically for inclusion therein; provided, further, that with respect to any
such untrue statement or omission made in any preliminary Prospectus, the
indemnity agreement contained in this Section 8(a) shall not inure to the
benefit of the Holder from whom the Person asserting any such losses, claims,
damages or liabilities purchased the Notes or Exchange Notes concerned if, to
the extent that such sale was a sale by the Holder, any such loss, claim, damage
or liability of such Holder is a result of the fact that both (A) a copy of the
Prospectus (or the Prospectus as then amended or supplemented) was not sent or
given to such Person at or prior to written confirmation of the sale of such
Notes or Exchange Notes to such Person and (B) the untrue statement or omission
in the preliminary Prospectus was corrected in the Prospectus (or the Prospectus
as then amended or supplemented) unless such failure to deliver the Prospectus
was a result of noncompliance by the Company with Section 6(d)(v) hereof. The
foregoing indemnity agreement is in addition to any liability which the Company
may otherwise have to any Holder or to any officer, employee or controlling
Person of that Holder.

                  (b) Each Holder, severally and not jointly, shall indemnify
and hold harmless each of the Company, its directors, officers and employees,
and each Person, if any, who controls the Company within the meaning of the
Securities Act, from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof, to which the Company or any such
director, officer or controlling Person may become subject, under the Securities
Act or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon (i) any untrue statement or alleged untrue
statement of a material fact contained (A) in any Registration Statement,
preliminary Prospectus or Prospectus, or in any amendment or supplement thereto
or (B) in any Blue Sky Application or (ii) the omission or alleged omission to
state in any Registration Statement, preliminary Prospectus or Prospectus, or in
any amendment or supplement thereto, or in any Blue Sky Application any material
fact required to be stated therein or necessary to make the statements therein
not misleading, but in each case only to the extent

                                      -17-
<PAGE>

that the untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
concerning such Holders furnished to the Company by or on behalf of that Holder
specifically for inclusion therein and shall reimburse each of the Company and
each such director, officer, employee and controlling Person for any legal or
other expenses reasonably incurred by such Company or each such director,
officer, employee or controlling Person in connection with investigating or
defending or preparing to defend against any such loss, claim, damage, liability
or action as such expenses are incurred. The foregoing indemnity agreement is in
addition to any liability which any Holder may otherwise have to either of the
Company or any such director, officer, employee or controlling Person.

                  (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 8, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 8 except to the extent it has
been materially prejudiced by such failure and; provided, further, that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified party otherwise than under this Section 8.
If any such claim or action shall be brought against an indemnified party, and
it shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof
with counsel reasonably satisfactory to the indemnified party. After notice from
the indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 8 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, any
indemnified party shall have the right to employ separate counsel in any such
action and to participate in the defense thereof but the fees and expenses of
such counsel shall be at the expense of the indemnified party unless (i) the
employment of such counsel has been specifically authorized by the indemnifying
party in writing, (ii) such indemnified party shall have been advised by such
counsel that there may be one or more legal defenses available to it which are
different from or additional to those available to the indemnifying party and in
the reasonable judgment of such counsel it is advisable for such indemnified
party to employ separate counsel or (iii) the indemnifying party has failed to
assume the defense of such action and employ counsel reasonably satisfactory to
the indemnified party, in which case, if such indemnified party notifies the
indemnifying party in writing that it elects to employ separate counsel at the
expense of the indemnifying party, the indemnifying party shall not, in
connection with any one such action or separate but substantially similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses of
more than one separate firm of attorneys (in addition to one local counsel) at
any time for all such indemnified parties, which firm shall be designated in
writing by (x) Credit Suisse First Boston Corporation and Lehman Brothers Inc.,
if the indemnified parties under this Section 8 consist of the Initial
Purchasers or any of their respective officers, employees or controlling
Persons, or (y) by the Company, if the indemnified parties under this Section 8
consist of any of the Company or any of its directors, officers,

                                      -18-

employees or controlling Persons. No indemnifying party shall (i) without the
prior written consent of the indemnified parties (which consent shall not be
unreasonably withheld), settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding or (ii) be liable for any
settlement of any such action effected without its written consent (which
consent shall not be unreasonably withheld), but if settled with the consent of
the indemnifying party or if there be a final judgment of the plaintiff in any
such action, the indemnifying party agrees to indemnify and hold harmless any
indemnified party from and against any loss or liability by reason of such
settlement or judgment.

                  (d) If the indemnification provided for in this Section 8
shall for any reason be unavailable to or insufficient to hold harmless an
indemnified party under Section 8(a) or 8(b) in respect of any loss, claim,
damage or liability, or any action in respect thereof, referred to therein, then
each indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company, on the one hand, and the Holders on the other, from the
sale of the Transfer Restricted Securities or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company, on the one hand, and the
Holders, on the other, with respect to the statements or omissions which
resulted in such loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant equitable considerations. The relative fault shall
be determined by reference to whether the untrue or alleged untrue statement of
a material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company, on the one hand, or the Holders, on the
other hand, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Holders agree that it would not be just and equitable if
contributions pursuant to this Section 8(d) were to be determined by pro rata
allocation (even if the Holders were treated as one entity for such purpose) or
by any other method of allocation which does not take into account the equitable
considerations referred to herein. The amount paid or payable by an indemnified
party as a result of the loss, claim, damage or liability, or action in respect
thereof, referred to above in this Section shall be deemed to include, for
purposes of this Section 8(d), any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this Section 8(d), no Holder
shall be required to contribute any amount in excess of the amount by which the
net proceeds received by it in connection with its sale of Notes exceeds the
amount of any damages which such Holder has otherwise paid or become liable to
pay by reason of the untrue or alleged untrue statement or omission or alleged
omission. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation. The Holders'
obligations to contribute as provided in this Section 8(d) are several and not
joint.

         9. RULE 144A.

                  The Company hereby agrees with each Holder of Transfer
Restricted Securities, during any period in which the Company is not subject to
Section 13 or 15(d) of the Exchange Act within the two-year period following the
Closing Date, to make available to any Holder or beneficial owner of Transfer
Restricted Securities, in connection with any sale thereof and any prospective
purchaser of such Transfer Restricted Securities from such Holder or beneficial
owner, the information required by Rule 144A(d)(4) under the Securities Act in
order to permit resales of such Transfer Restricted Securities pursuant to Rule
144A.

         10. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.

                  No Holder may participate in any Underwritten Registration
hereunder unless such Holder (a) agrees to sell such Holder's Transfer
Restricted Securities on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements and (b)
completes and executes all reasonable questionnaires, powers of attorney,
indemnities, underwriting agreements, lock-up letters and other documents
required under the terms of such underwriting arrangements.

         11. SELECTION OF UNDERWRITERS.

                  Subject to Section 6(d)(i), the Holders of Transfer Restricted
Securities covered by the Shelf Registration Statement who desire to do so may
sell such Transfer Restricted Securities in an Underwritten Offering at such
Holders' expense. In any such Underwritten Offering, the investment banker or
investment bankers and manager or managers that will administer the offering
will be selected by the Holders of a majority in aggregate principal amount of
the Transfer Restricted Securities included in such offering; provided that such
investment bankers and managers must be reasonably satisfactory to the Company.

         12. MISCELLANEOUS.

                  (a) Remedies. The Company agrees that monetary damages
(including Liquidated Damages) would not be adequate compensation for any loss
incurred by reason of a breach by it of the provisions of this Agreement and
hereby agree to waive the defense in any action for specific performance that a
remedy at law would be adequate.

                  (b) No Inconsistent Agreements. The Company will not, on or
after the date of this Agreement, enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the Holders in this
Agreement or otherwise conflicts with the provisions hereof. Except as disclosed
in the Offering Memorandum (as such term is defined in the Purchase Agreement),
the Company has not previously entered into any agreement granting any
registration rights with respect to its securities to any Person. The rights
granted to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of the Company's securities
under any agreement in effect on the date hereof.

<PAGE>

                  (c) Adjustments Affecting the Notes. The Company will not take
any action, or permit any change to occur, with respect to the Notes that would
materially and adversely affect the ability of the Holders to Consummate any
Exchange Offer.

                  (d) Amendments and Waivers. The provisions of this Agreement
may not be amended, modified or supplemented, and waivers or consents to or
departures from the provisions hereof may not be given unless the Company has
obtained the written consent of Holders of a majority of the outstanding
principal amount of the Transfer Restricted Securities affected by such
amendment, modification, supplement, waiver or consent. Notwithstanding the
foregoing, a waiver or consent to departure from the provisions hereof that
relates exclusively to the rights of Holders whose securities are being tendered
pursuant to the Exchange Offer and that does not affect directly or indirectly
the rights of other Holders whose securities are not being tendered pursuant to
such Exchange Offer may be given by the Holders of a majority of the outstanding
principal amount of Transfer Restricted Securities being tendered or registered.
