         "Make-Whole Premium" means an amount, with respect to any Note (or

Redemption Date, of (i) each interest payment that, but for such redemption,
would have been payable on the Note (or portion thereof) being redeemed on each
Interest Payment Date occurring after the Redemption Date (excluding any accrued
interest for the period prior to the Redemption Date) and (ii) the principal
amount that, but for such redemption, would have been payable at the final
maturity of the Note (or portion thereof) being redeemed; over (b) the principal
amount of the Note (or portion thereof) being redeemed. The present values of
interest and principal payments referred to in clauses (i) and (ii) above will
be determined in accordance with generally accepted principles of financial
analysis. Such present values will be calculated by discounting the amount of
each payment of interest or principal from the date that each such payment would
have been payable, but for the redemption, to the Redemption Date at a discount
rate equal to the Treasury Yield (as defined below) plus 20 basis points. The
Make-Whole Premium will be calculated by an independent investment banking
institution of national standing appointed by the Company; provided, that if the
Company fails to make such appointment at least 45 days prior to the Redemption
Date, or if the institution so appointed is unwilling or unable to make such
calculation, such calculation will be made by Merrill Lynch & Co. or if such
firm is unwilling or unable to make such calculation, by an independent
investment banking institution of national standing appointed by the Trustee (in
any such case, an "Independent Investment Banker"). For purposes of determining
the Make-Whole Premium, "Treasury Yield" means a rate of interest per annum
equal to the weekly average yield to maturity of United States Treasury Notes
that have a constant maturity that corresponds to the remaining term to maturity
of the Notes, calculated to the nearest 1/12th of a year (the "Remaining Term").
The Treasury Yield will be determined as of the third business day immediately
preceding the applicable Redemption Date. The weekly average yields of United
States Treasury Notes will be determined by reference to the most recent
statistical release published by the Federal Reserve Bank of New York and
designated "H.15(519) Selected Interest Rates" or any successor release (the
"H.15 Statistical Release"). If the H.15 Statistical Release sets forth a weekly
average yield for United States Treasury Notes having a constant maturity that
is the same as the Remaining Term, then the Treasury Yield will be equal to such
weekly average yield. In all other cases, the Treasury Yield will be calculated
by interpolation, on a straight-line basis, between the weekly average yields on
the United States Treasury Notes that have a constant maturity closest to and
greater than the Remaining Term and the United States Treasury Notes that have a
constant maturity closest to and less than the Remaining Term (in each case as
set forth in the H.15 Statistical Release). Any weekly average yields as
calculated by interpolation will be rounded to the nearest 1/100th of 1%, with
any figure of 1/200% or above being rounded upward. If weekly average yields for
United States Treasury Notes are not available in the H.15 Statistical Release
or otherwise, then the Treasury Yield will be calculated by interpolation of
comparable rates selected by the Independent Investment Banker.

Holders or the Trustee all money held by the Paying Agent for the payment of
principal of, or interest or premium, if any, on, the Notes, and will notify the
Trustee of any default by the Company in making any such payment. While any such
default continues, the Trustee may require a Paying Agent to pay all money held
by it to the Trustee. The Company at any time may require a Paying Agent to pay
all money held by it to the Trustee. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or a Subsidiary) shall have no further
liability for the money. If the Company or a Subsidiary acts as Paying Agent,


                                       13

         2.6(b)(ii) shall be deemed to have been satisfied upon receipt by the
         Registrar of the instructions contained in the Letter of Transmittal

   34

                           (iii) The Registrar shall not be required to register
         the transfer or exchange of any Note selected for redemption in whole
         or in part, except the unredeemed portion of any Note being redeemed in
         part.

                           (iv) All Global Notes and Definitive Notes issued
         upon any registration of transfer or exchange of Global Notes or
         Definitive Notes shall be the valid obligations of the Company,
         evidencing the same debt, and entitled to the same benefits under this
         Indenture, as the Global Notes or Definitive Notes surrendered upon
         such registration of transfer or exchange.

                           (v) The Company shall not be required (A) to issue,
         to register the transfer of or to exchange Notes during a period
         beginning at the opening of business 15 days before the day of mailing
         of a notice of redemption of Notes for redemption under Section 3.3
         hereof and ending at the close of business on the day of such mailing,
         (B) to register the transfer of or to exchange any Note so selected for
         redemption in whole or in part, except the unredeemed portion of any
         Note being redeemed in part or (C) to register the transfer of or to
         exchange a Note between a record date and the next succeeding Interest
         Payment Date.

                           (vi) Prior to due presentment for the registration of
         a transfer of any Note, the Trustee, any Agent and the Company may deem
         and treat the Person in whose name any Note is registered as the
         absolute owner of such Note for the purpose of receiving payment of
         principal of and interest on such Notes and for all other purposes, and
         none of the Trustee, any Agent or the Company shall be affected by
         notice to the contrary.

                           (vii) The Trustee shall authenticate Global Notes and
         Definitive Notes in accordance with the provisions of Section 2.2
         hereof.

                           (viii) All certifications, certificates and Opinions
         of Counsel required to be submitted to the Registrar pursuant to this
         Section 2.6 to effect a transfer or exchange may be submitted by
         facsimile.

                           (ix) Each Holder of a Note agrees to indemnify the
         Company and the Trustee against any liability that may result from the
         transfer, exchange or assignment of such Holder's Note in violation of
         any provision of this Indenture and/or applicable United States federal
         or state securities law.

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


                                       28
   35

         terms of, this Indenture, and to examine the same to determine
         substantial compliance as to form with the express requirements hereof.

SECTION 2.7       Replacement Notes.

         If any mutilated Note is surrendered to the Trustee or the Company and
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Note, the Company shall issue and the Trustee, upon the written
order of the Company signed by two Officers of the Company, shall authenticate a
replacement Note if the Trustee's requirements are met. An indemnity bond must
be supplied by the Holder that is sufficient in the judgment of the Trustee and
the Company to protect the Company, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Note is
replaced. The Company may charge for its expenses in replacing a Note.

         Every replacement Note is an additional obligation of the Company and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder.

SECTION 2.8       Outstanding Notes.

         The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section as not outstanding. Except as set forth in Section 2.9 hereof, a Note
does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Note.

         If a Note is replaced pursuant to Section 2.7 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

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

         If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Notes payable on that date, then on and after that date such
Notes shall be deemed to be no longer outstanding and shall cease to accrue
interest.

SECTION 2.9       Treasury Notes.

         In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company, shall be considered as
though not outstanding, except that for the purposes of determining whether


                                       29
   36

the Trustee shall be protected in relying on any such direction, waiver or
consent, only Notes that a Responsible Officer of the Trustee actually knows are
so owned shall be so disregarded.

SECTION 2.10      Temporary Notes.

         Until Definitive Notes are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Notes upon a written order of the
Company signed by two Officers of the Company. Temporary Notes shall be
substantially in the form of Definitive Notes but may have variations that the
Company considers appropriate for temporary Notes and as shall be reasonably
acceptable to the Trustee. Without unreasonable delay, the Company shall prepare
and the Trustee shall authenticate Definitive Notes in exchange for temporary
Notes.

         Holders of temporary Notes shall be entitled to all of the benefits of
this Indenture.

SECTION 2.11      Cancellation.

         The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall return such
canceled Notes to the Company. The Company may not issue new Notes to replace
Notes that it has paid or that have been delivered to the Trustee for
cancellation.

SECTION 2.12      Defaulted Interest.

         If the Company defaults in a payment of interest on the Notes, it shall
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.1 hereof. The Company shall promptly notify the Trustee in
writing of the amount of defaulted interest proposed to be paid on each Note and
the date of the proposed payment. The Company shall fix or cause to be fixed
each such special record date and payment date, provided that no such special
record date shall be less than 10 days prior to the related payment date for
such defaulted interest. At least 15 days before the special record date, the
Company (or, upon the written request of the Company, the Trustee in the name
and at the expense of the Company) shall mail or cause to be mailed to Holders a
notice that states the special record date, the related payment date and the
amount of such interest to be paid.

SECTION 2.13      CUSIP Numbers.

         The Company in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as contained in any notice of a redemption and
that


                                       30
   37

reliance may be placed only on the other identification numbers printed on the
Notes, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company will promptly notify the Trustee of any
change in the "CUSIP" numbers.

                                      ARTICLE III

                                       REDEMPTION

SECTION 3.1       Redemption at the Option of the Company.

           The Notes are redeemable prior to the Stated Maturity of principal,
at the option of the Company, at any time in whole or from time to time in part,
upon the delivery of the notices provided in Sections 3.2 and 3.4 hereof, on any
date prior to the Stated Maturity of principal selected by the Company (the
"Redemption Date") at a price equal to 100% of the principal amount thereof plus
accrued and unpaid interest, if any, to the Redemption Date (subject to the
right of Holders on the relevant record date to receive interest due on an
Interest Payment Date that is on or prior to the Redemption Date) plus the
Make-Whole Premium, if any (the "Redemption Price"). In no event will the
Redemption Price ever be less than 100% of the principal amount of the Notes
plus accrued interest to the Redemption Date.

SECTION 3.2       Notice to the Trustee.

         If the Company elects to redeem Notes pursuant to this Article III, it
shall notify the Trustee of the Redemption Date and principal amount of the
Notes to be redeemed. The Company shall so notify the Trustee at least 45 days
before the Redemption Date (unless a shorter notice shall be satisfactory to the
Trustee) by delivering to the Trustee an Officers' Certificate stating that such
redemption will comply with the provisions of this Indenture and of the Notes.
Any such notice may be canceled at any time prior to the mailing of such notice
of such redemption to any Holder and shall thereupon be void and of no effect.

SECTION 3.3       Selection of Notes To Be Redeemed.

         If less than all the Notes are to be redeemed, the particular Notes to
be redeemed shall be selected not more than 60 days prior to the Redemption Date
by the Trustee, from the outstanding Notes not previously called for redemption,
pro rata, by lot or by such other method as the Trustee shall deem fair and
appropriate and that may provide for the selection for redemption of portions
(equal to the minimum authorized denomination for Notes or any integral multiple
thereof) of the principal amount of Notes of a denomination larger than the
minimum authorized denomination or of the principal amount of Global Notes.

         The Trustee shall promptly notify the Company and the Registrar in
writing of the Notes selected for redemption and, in the case of any Notes
selected for partial redemption, the principal amount thereof to be redeemed.


                                       31
   38

         For purposes of this Indenture, unless the context otherwise requires,
all provisions relating to redemption of Notes shall relate, in the case of any
of the Notes redeemed or to be redeemed only in part, to the portion of the
principal amount thereof which has been or is to be redeemed.

SECTION 3.4       Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Notes to be redeemed, at the address of such Holder
appearing in the register of Notes maintained by the Registrar.

         All notices of redemption shall identify the Notes to be redeemed
(including CUSIP numbers) and shall state:

                                             (1) the Redemption Date;

                                             (2) the Redemption Price (excluding
                  the amount of any Make-Whole Premium, if any);

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

                                             (4) if any Note is to be redeemed
                  in part, the portion of the principal amount thereof to be
                  redeemed and that on and after the redemption date, upon
                  surrender for cancellation of such Note to the Paying Agent, a
                  new Note or Notes in the aggregate principal amount equal to
                  the unredeemed portion thereof will be issued without charge
                  to the Holder;

                                             (5) that Note called for redemption
                  must be surrendered to the Paying Agent to collect the
                  Redemption Price and the name and address of the Paying Agent;

                                             (6) the CUSIP number, if any,
                  relating to such Notes.

         Notice of redemption of Notes to be redeemed at the election of the
Company shall be given by the Company or, at the Company's written request, by
the Trustee in the name and at the expense of the Company.


                                       32
   39

SECTION 3.5       Effect of Notice of Redemption.

         Once notice of redemption is mailed, Notes called for redemption become
due and payable on the Redemption Date and at the Redemption Price. Upon
surrender to the Paying Agent, such Notes called for redemption shall be paid at
the Redemption Price, but interest installments whose maturity is on or prior to
such Redemption Date will be payable on the day payment of such interest is due
to the Holders of record at the close of business on the relevant record dates
specified pursuant in Section 2.1 hereof and the Notes.

SECTION 3.6       Deposit of Redemption Price.

         On or prior to 10:00 a.m., New York City time, on any Redemption Date,
the Company shall deposit with the Trustee or the Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 2.4) an amount of money in same day funds sufficient to pay
the Redemption Price of, including (except if the Redemption Date shall be a
date interest is due under the Notes) accrued and unpaid interest if any, on,
the Notes or portions thereof which are to be redeemed on that date, other than
Notes or portions thereof called for redemption on that date which have been
delivered by the Company to the Trustee for cancellation.

         If the Company complies with the preceding paragraph, then, unless the
Company defaults in the payment of such Redemption Price, interest on the Notes
to be redeemed will cease to accrue on and after the applicable Redemption Date,
whether or not such Notes are presented for payment, and the Holders of such
Notes shall have no further rights with respect to such Notes except for the
right to receive the Redemption Price upon surrender of such Notes. If any Notes
called for redemption shall not be so paid upon surrender thereof for
redemption, the principal, premium, if any, and, to the extent lawful, accrued
and unpaid interest thereon shall, until paid, bear interest from the Redemption
Date at the rate applicable to such Notes.

SECTION 3.7       Notes Redeemed or Purchased in Part.

         Upon surrender to the Paying Agent of a Note to be redeemed in part,
the Company shall execute and the Trustee shall authenticate and make available
for delivery to the Holder of such Note without service charge a new Note or
Notes, and of any authorized denomination as requested by such Holder in
aggregate principal amount equal to, and in exchange for, the unredeemed portion
of the principal of the Note so surrendered that is not redeemed.

SECTION 3.8       Purchase of Notes.

         The Company and any Affiliate of the Company may at any time purchase
or otherwise acquire Notes in the open market or by private agreement. Such
acquisition shall not operate as or be deemed for any purpose to be a redemption
of the indebtedness represented by such Notes. Any Notes purchased or acquired
by the Company may be delivered to the Trustee and, upon such


                                       33
   40

delivery, the indebtedness represented thereby shall be deemed to be satisfied.
Section 2.9 shall apply to all Notes so delivered.

                                   ARTICLE IV

                                    COVENANTS

SECTION 4.1       Payment of Notes.

         The Company shall pay or cause to be paid the principal of, premium, if
any, and interest on, the Notes on the dates and in the manner provided in the
Notes and this Indenture. Principal and interest, if any, shall be considered
paid on the date due if the Paying Agent, if other than the Company or a
Subsidiary thereof, holds as of 10:00 a.m. New York City Time on the due date
money deposited by the Company in immediately available funds and designated for
and sufficient to pay all principal, premium, if any, and interest then due. The
interest rate applicable to the Notes is subject to increase upon the occurrence
of certain events as provided in the Registration Rights Agreement.

         The Company shall pay interest on overdue principal at the rate borne
on the Notes to the extent lawful; it shall pay on overdue installments of
interest (without regard to any applicable grace period) at the same rate to the
extent lawful.

SECTION 4.2       Maintenance of Office or Agency.

         The Company shall maintain in the Borough of Manhattan, the City of New
York, an office or agency (which may be an office of the Trustee or an affiliate
of the Trustee, Registrar or co-registrar) where Notes may be surrendered for
registration of transfer or for exchange and where notices and demands to or
upon the Company in respect of the Notes and this Indenture may be served. The
Company shall give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee.

         The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York for such purposes. The Company shall give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.


                                       34
   41

         The Company hereby designates the office of the Trustee at 101 Barclay
Street, Floor 21 West, New York, New York 10286, as one such office or agency of
the Company in accordance with Section 2.3 hereof.

SECTION 4.3       Statement by Officers as to Default.

         The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the knowledge of the signers thereof a
Default or Event of Default, specifying all such Defaults or Events of Defaults
(as applicable) and the nature and status thereof.

         The Company shall deliver to the Trustee, as soon as possible and in
any event within five days after the Company becomes aware of the occurrence of
any Event of Default or Default, an Officers' Certificate setting forth the
details of such Event of Default or Default and the action which the Company
proposes to take with respect thereto.


SECTION 4.4       Corporate Existence.

         Subject to Article 5, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect (i) its corporate
existence, and the corporate, partnership or other existence of each of its
Restricted Subsidiaries, in accordance with the respective organizational
documents (as the same may be amended from time to time) of the Company or any
such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses
and franchises of the Company and its Restricted Subsidiaries; provided,
however, that the Company shall not be required to preserve any such right,
license or franchise, or the corporate, partnership or other existence of any of
its Restricted Subsidiaries, if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and its Restricted Subsidiaries, taken as a whole, and that the loss
thereof is not adverse in any material respect to the Holders of the Notes.

SECTION 4.5       SEC Reports; Financial Statements.

                  (a) The Company shall file with the Trustee, within 15 days
after it files the same with the SEC, copies of the annual reports and the
information, documents and other reports (or copies of such portions of any of
the foregoing) as the SEC may by rules and regulations prescribe that the
Company is required to file with the SEC pursuant to Section 13 or 15(d) of the
Exchange Act. The Company shall also comply with the provisions of TIA Section
314(a).

                  (b) If the Company is not subject to the requirements of
Section 13 or 15(d) of the Exchange Act, the Company shall furnish to all
Holders of the Rule 144A Global Note or Holders that qualify as QIB's who have
elected to take physical delivery of a Restricted Definitive Note, and
prospective purchasers who are acquiring a Restricted Definitive Note or a
beneficial


                                       35
   42

interest in the Rule 144A Global Note as a QIB in accordance with Rule 144A,
promptly upon their request, the information required to be delivered pursuant
to clause (d)(4) of Rule 144A.

                  (c) Delivery of such reports, information and documents to the
Trustee under this Section 4.5 is for informational purposes only and the
Trustee's receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained
therein, including the Company's compliance with any of its covenants under this
Article IV (as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).

SECTION 4.6       Limitation on Liens.

         So long as any of the Notes are outstanding, the Company shall not at
any time create, incur, assume or guarantee, and shall not cause, suffer or
permit a Restricted Subsidiary to create, incur, assume or guarantee, any
Secured Debt without making effective provision (and the Company covenants that
in such case it will make or cause to be made such effective provision) whereby
the Notes then outstanding and any other indebtedness of or guaranteed by the
Company or any Restricted Subsidiary then entitled thereto, subject to
applicable priorities of payment, shall be secured, by such Lien equally and
ratably with any and all other obligations and indebtedness thereby secured, so
long as such other obligations and indebtedness shall be so secured; provided,
that if any such Lien securing such Secured Debt ceases to exist, such equal and
ratable security for the benefit of the Holders of Notes shall automatically
cease to exist without any further action; provided, further, that if such
Secured Debt is expressly subordinated to the Notes, the Lien securing such
subordinated Secured Debt shall be subordinate and junior to the Lien securing
the Notes with the same relative priority as such Secured Debt shall have with
respect to the Notes; and provided further, that the foregoing covenants shall
not be applicable to the Secured Debt that is secured by Permitted Liens.

         Notwithstanding the foregoing provisions of this Section 4.6, the
Company and its Restricted Subsidiaries may, without equally and ratably
securing the Notes, create, incur, assume or guarantee Secured Debt not
otherwise permitted or excepted if the sum of (a) the amount of such Secured
Debt plus (b) the aggregate value of Sale and Leaseback Transactions (excluding
Sale and Leaseback Transactions identified in (a) through (d) of Section 4.7),
does not exceed 10% of Consolidated Net Tangible Assets (as shown in the
quarterly consolidated balance sheet of the Company most recently published
prior to the date of creation, incurrence, assumption or guarantee).

SECTION 4.7       Limitation on Sale and Leaseback Transactions.

         The Company will not, nor will it permit any of its Restricted
Subsidiaries to, engage in a Sale and Leaseback Transaction, unless: (a) such
Sale and Leaseback Transaction occurs within one year from the date of
completion of the acquisition of the Principal Property subject thereto or the
date of the completion of construction, development or substantial repair or
improvements, or commencement of full operations, on such Principal Property,
whichever is later, (b) the Sale and Leaseback Transaction involves a lease for
a period, including renewals, of not more than three


                                       36
   43

years, (c) the Company or such Restricted Subsidiary would be entitled to incur
Secured Debt secured by a Lien on the Principal Property subject thereto in a
principal amount equal to or exceeding the net sale proceeds from such Sale and
Leaseback Transaction without equally and ratably securing the Notes pursuant to
Section 4.6, or (d) the Company or such Restricted Subsidiary, within a one-year
period after the Sale and Leaseback Transaction, applies or causes to be applied
an amount not less than the net sale proceeds from such Sale and Leaseback
Transaction to (i) the redemption of the Notes or the prepayment, repayment,
reduction or retirement of any indebtedness of the Company or any of its
subsidiaries that ranks pari passu with the Notes or (ii) the expenditure or
expenditures for Principal Property used or to be used in the ordinary course of
business of the Company or any of its Restricted Subsidiaries.

         Notwithstanding the foregoing, the Company may, and may permit each of
its Restricted Subsidiaries, to, effect any Sale and Leaseback Transaction that
is not excepted by clauses (a) through (d) (inclusive) of the above paragraph,
provided that, after giving effect thereto and the application of proceeds, if
any, received by the Company or any its Restricted Subsidiaries as a result
thereof, the net sale proceeds from such Sale and Leaseback Transaction,
together with the aggregate principal amount of all Secured Debt then
outstanding (other than the Notes) secured by Liens upon Principal Property
(which are not Permitted Liens) would not exceed 10% of the Consolidated Net
Tangible Assets (as shown in the quarterly consolidated balance sheet of the
Company most recently published prior to the date the Sale and Leaseback
Transaction is effected).

SECTION 5.1       Consolidation, Merger, or Sale of Assets.

         The Company may (a) consolidate with or merge into, or (b) sell,
convey, transfer, lease or otherwise dispose of its properties and assets
substantially as an entirety to, any Person, provided that (i) in the case of
any such consolidation or merger, the Company is the continuing entity or, if
the Company is not the continuing entity, the continuing entity is a Person
organized and validly existing under the laws of the United States, any
political subdivision thereof or any State thereof and assumes by supplemental
indenture all of the Company's obligations on the Notes and under the Indenture,
and (ii) after giving effect to the transaction no Event of Default, and no
event which, after notice or lapse of time or both, would become an Event of
Default, shall exist. Upon a disposition of assets described in clause (b) of
the preceding sentence, the Company will be released from any further liability
under the Notes and the Indenture.

SECTION 5.2       Successor Corporation Substituted.

         Upon any consolidation or merger, transfer or lease of its properties

Company is merged or to which such conveyance, transfer or


                                       37
   44

lease of its properties and assets is made shall succeed to, and be substituted
for (so that from and after the date of such consolidation or merger, or
conveyance transfer or lease of its property and assets substantially as an
entirety, the provisions of this Indenture referring to the "Company" shall
refer instead to the successor corporation and not to the Company), and may
exercise every right and power of the Company under this Indenture with the same
effect as if such successor Person had been named as the Company herein.

                                   ARTICLE VI

                              DEFAULTS AND REMEDIES

SECTION 6.1       Events of Default.

         An "Event of Default" occurs hereunder with respect to the Notes if:

                  (a) the Company defaults in the payment when due of principal
of or Make-Whole Premium, if any, on, the Notes;

                  (b) the Company defaults in payment when due of interest on

described in clauses (a) or (b) above) in the Notes or this Indenture for 60
days after notice to the Company by the Trustee or the Holders of at least 25%
in aggregate principal amount of the Notes then outstanding;

                  (d) indebtedness of the Company or any Subsidiary is not paid
when due within the applicable grace period, if any, or is accelerated by the
holders thereof and, in either case, the principal amount of such unpaid or
accelerated indebtedness exceeds $20 million;

                  (e) the Company or any of its Significant Subsidiaries or any
group of Subsidiaries that, when taken together, would constitute a Significant
Subsidiary:

                           (i) commences a voluntary case,

                           (ii) consents to the entry of an order for relief
         against it in an involuntary case,

                           (iii) consents to the appointment of a custodian of
         it or for all or substantially all of its property, or

                                       38
   45

                  (f) a court of competent jurisdiction enters an order or
decree under the Bankruptcy Code that:

                           (i) is for relief against the Company or any of its
         Significant Subsidiaries or any group of Subsidiaries that, when taken
         together, would constitute a Significant Subsidiary, in an involuntary
         case;

                           (ii) appoints a Custodian of the Company or any of
         its Significant Subsidiaries or any group of Subsidiaries that, when

         Subsidiaries that, when taken together, would constitute a Significant
         Subsidiary; or

                           (iii) orders the liquidation of the Company or any of
         its Significant Subsidiaries or any group of Subsidiaries that, when
         taken together, would constitute a Significant Subsidiary;

         and the order or decree remains unstayed and in effect for 60
         consecutive days.

SECTION 6.2       Acceleration.

         If any Event of Default (other than an Event of Default specified in
clauses (e) or (f) of Section 6.1) shall occur and be continuing, either the
Trustee or the Holders of at least 25% of the then outstanding Notes by notice
to the Company may declare the principal amount of the Notes to be due and
payable immediately. If an Event of Default specified in clauses (e) or (f) of
Section 6.1 shall occur, the principal amount of all the then outstanding Notes
will automatically, and without any action by the Trustee or any Holder, become
immediately due and payable. After any acceleration, but before a judgment or
decree for the payment of the money due has been obtained by the Trustee, the
Holders of a majority in aggregate principal amount of the then outstanding
Notes, by written notice to the Trustee, may rescind and annul such acceleration
and its consequences if all Events of Default, other than the non-payment of
accelerated principal, have been cured or waived pursuant to the terms of this
Indenture.

SECTION 6.3       Other Remedies.

         If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal, premium, if any and
accrued and unpaid interest, if any, on the Notes or to enforce the performance
of any provision of the Notes or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Note in exercising any right or
remedy accruing upon an Event of Default shall not impair the right


                                       39
   46

or remedy or constitute a waiver of or acquiescence in the Event of Default. All
remedies are cumulative to the extent permitted by law.

SECTION 6.4       Waiver of Past Defaults.

         The Holders of a majority in aggregate principal amount of the
outstanding Notes may on behalf of the Holders of all of the Notes waive any
past default hereunder and its consequences, except a Default:

                  (a) in the payment of the principal of or any premium or
interest on any Note, or

                  (b) in respect of any other covenant or provision hereof
which, under Section 9.2 hereof, cannot be modified or amended without the
consent of the Holder of each outstanding Note.

         Upon any such waiver, such Default or Event of Default shall cease to
exist and shall be deemed to have been cured, for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereon.

SECTION 6.5       Control by Majority.

         Subject to Section 7.2(f) hereof, Holders of a majority in principal
amount of the then outstanding Notes (together as a single class) may direct the
time, method and place of conducting any proceeding for exercising any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee.

SECTION 6.6       Limitation on Suits.

         A Holder of a Note may institute any proceeding with respect to the
Indenture, or for the appointment of a receiver or a trustee, or for any other
remedy thereunder with respect to this Indenture or the Note only if:

                  (a) the Holder of a Note has previously given to the Trustee
written notice of a continuing Event of Default;

                  (b) the Holders of at least 25% in aggregate principal amount
of the Notes make a written request to the Trustee to institute a proceeding or
pursue a remedy as trustee;

                  (c) such Holder of a Note or Holders of Notes offer and, if
requested, provide to the Trustee indemnity satisfactory to the Trustee against
any loss, liability or expense to be incurred in compliance with such request;

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


                                       40
   47

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

A Holder of a Note may not use this Indenture to prejudice the rights of another
Holder of a Note or to obtain a preference or priority over another Holder of a
Note or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all of such Holders.

SECTION 6.7       Rights of Holders of Notes to Receive Payment and Institute
                  Proceedings.

         Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal of, and premium, if any, and
interest on, the Note on or after the respective due dates expressed in the
Note, or to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired, affected or limited in any way
(including by any limitation set forth in Section 6.6 hereof) without the
consent of the Holder of each Note affected thereby.

SECTION 6.8       Collection Suit by Trustee.

         If an Event of Default specified in Section 6.1(a) or (b) hereof occurs
and is continuing, the Trustee is authorized to recover judgment in its own name
and as trustee of an express trust against the Company for the whole amount of
principal of, and premium, if any, and interest remaining unpaid on, the Notes
and interest on overdue principal and, to the extent lawful, interest and such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

SECTION 6.9       Trustee May File Proofs of Claim.

         The Trustee is authorized to file such proofs of claim and other papers
or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property and shall
be entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.7 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 7.7 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a Lien on,


                                       41
   48

and shall be paid out of, any and all distributions, dividends, money,
securities and other properties that the Holders may be entitled to receive in
such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting any Notes or the rights of any Holder, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10      Priorities.

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

         First: to the Trustee, its agents and attorneys for amounts due under
Section 7.7 hereof, including payment of all compensation, expense, and
liabilities incurred, and all advances made, by the Trustee and the costs and
expenses of collection;

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

         Third: to the Company or to such party as a court of competent
jurisdiction shall direct.

         The Trustee may fix a record date and payment date for any payment to
Holders of Notes pursuant to this Section 6.10.

SECTION 6.11      Undertaking for Costs.

         In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the cost of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section does not apply to a suit by the Trustee, a suit by a
Holder of a Note pursuant to Section 6.7 hereof, or a suit by Holders of more
than 10% in principal amount of the then outstanding Notes.

                                     TRUSTEE

SECTION 7.1       Duties of Trustee.

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

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

                           (i) The Trustee need perform only those duties that
         are specifically set forth in this Indenture and the TIA and no others,
         and no implied covenants or obligations shall be read into this
         Indenture against the Trustee. To the extent of any conflict between
         the duties of the Trustee hereunder and under the TIA, the TIA shall
         control.

                           (ii) In the absence of bad faith on its part, the
         Trustee may conclusively rely, as to the truth of the statements and
         the correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, in the case of any such certificates or
         opinions which by any provision hereof are specifically required to be
         furnished to the Trustee, the Trustee shall examine the certificates
         and opinions to determine whether or not they conform to the
         requirements of this Indenture (but need not confirm or investigate the
         accuracy of mathematical calculations or other facts stated therein).

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

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

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

                           (iii) the Trustee shall not be liable with respect to
         any action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.5 hereof.


                                       43
   50

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

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

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

SECTION 7.2       Rights of Trustee.

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

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

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

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

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

                  (f) Subject to Section 7.1(b) hereof, the Trustee shall be
under no obligation to exercise any of the rights or powers vested in it by this
Indenture at the request or direction of any of the Holders unless such Holders
shall have offered to the Trustee security or indemnity satisfactory to the
Trustee against the costs, expenses and liabilities (including fees and expenses
of its agents and counsel) that might be incurred by it in compliance with such
request or direction.

   51



                  (g) The Trustee, in its individual or other capacity, may make
loans to, accept deposits from, and perform services for, the Company or its
Affiliates, and may otherwise deal with the Company or its Affiliates, as if it
were not the Trustee, including, without limitation, as a lender under the
Company's Senior Credit Facility.

                  (h) The Trustee shall not be deemed to have notice of any
Default or Event of Default unless a Responsible Officer of the Trustee has
actual knowledge thereof or unless written notice of any event which is in fact
such a default is received by the Trustee at the Corporate Trust Office of the
Trustee, and such notice references the Notes and this Indenture.

                  (i) The rights, privileges, protections, immunities and
benefits given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder.

SECTION 7.3       Individual Rights of Trustee.

         The Trustee, any Paying Agent, any authenticating agent or registrar in
its individual or any other capacity may become the owner or pledgee of Notes
and may otherwise deal with the Company or any Affiliate of the Company with the
same rights it would have if it were not Trustee. However, in the event that the
Trustee acquires any conflicting interest it must eliminate such conflict within
90 days, apply to the SEC for permission to continue as trustee or resign. Any
Agent may do the same with like rights and duties. The Trustee is also subject
to Sections 7.10 and 7.11 hereof.

SECTION 7.4       Trustee's Disclaimer.

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

SECTION 7.5       Notice of Defaults.

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

   52

SECTION 7.6       Reports by Trustee to Holders of the Notes.

         Within 60 days after each June 15 beginning with the June 15 following
the date of this Indenture, and for so long as the Notes remain outstanding, the
Trustee shall mail to the Holders of the Notes a brief report dated as of such
reporting date that complies with TIA Section 313(a) (but if no event described
in TIA Section 313(a) has occurred within the twelve months preceding the
reporting date, no report need be transmitted). The Trustee also shall comply
with TIA Section 313(b)(2). The Trustee shall also transmit by mail all reports
as required by TIA Section 313(c).

         A copy of each report at the time of its mailing to the Holders of
Notes shall be mailed to the Company and filed with the SEC and each stock
exchange on which Notes are listed in accordance with TIA Section 313(d). The
Company shall promptly notify the Trustee when the Notes are listed on any stock
exchange or delisted therefrom.

SECTION 7.7       Compensation and Indemnity.

         The Company shall pay to the Trustee from time to time such
compensation for its acceptance of this Indenture and services hereunder as the
parties shall agree from time to time. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Company
shall reimburse the Trustee promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by it in addition to the
compensation for its services. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

         The Company shall indemnify the Trustee against any and all losses,
liabilities, claims, damages or expenses incurred by it arising out of or in
connection with the acceptance or administration of its duties under this
Indenture, including the costs and expenses of enforcing this Indenture against
the Company (including this Section 7.7) and defending itself against any claim
(whether asserted by the Company or any Holder or any other person) or liability
in connection with the exercise or performance of any of its powers or duties
hereunder, except to the extent any such loss, liability, claim, damage or
expense may be attributable to its negligence or bad faith. The Trustee shall
notify the Company promptly of any claim for which it may seek indemnity.
Failure by the Trustee to so notify the Company shall not relieve the Company of
its obligations hereunder. The Company shall defend the claim and the Trustee
shall cooperate in the defense. The Trustee may have separate counsel and the
Company shall pay the reasonable fees and expenses of such counsel. The Company
need not pay for any settlement made without its consent, which consent shall
not be unreasonably withheld.

         The obligations of the Company under this Section 7.7 shall survive the
satisfaction and discharge of this Indenture.

         To secure the Company's payment obligations in this Section, the
Trustee shall have a Lien prior to any of the Notes on all money or property
held or collected by the Trustee, except that held


                                       46
   53

in trust to pay principal and interest on particular Notes. Such Lien shall
survive the satisfaction and discharge of this Indenture.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.1(e) or (f) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under the
Bankruptcy Code.

         The Trustee shall comply with the provisions of TIA Section 313(b)(2)
to the extent applicable.

SECTION 7.8       Replacement of Trustee.

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

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

                  (a) the Trustee fails to comply with Section 7.10 hereof,

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

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

                  (d) the Trustee becomes incapable of acting.

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

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

         If the Trustee, after written request by any Holder of a Note who has
been a Holder of a Note for at least six months, fails to comply with Section
7.10 hereof, such Holder of a Note may, at the expense of the Company, petition
any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee.


                                       47
   54

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Notes. The retiring Trustee shall promptly transfer
all property held by it as Trustee to the successor Trustee, provided all sums
owing to the Trustee hereunder have been paid and subject to the Lien provided
for in Section 7.7 hereof. Notwithstanding replacement of the Trustee pursuant
to this Section 7.8, the Company's obligations under Section 7.7 hereof shall
continue for the benefit of the retiring Trustee.

SECTION 7.9       Successor Trustee by Merger, Etc.

         If the Trustee consolidates, merges or converts into, or transfers all
or substantially all of its corporate trust business to, another corporation,
the successor corporation without any further act shall be the successor
Trustee.

SECTION 7.10      Eligibility; Disqualification.

         There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has, or is the subsidiary of a bank holding company that
has, a combined capital and surplus of at least $50,000,000 as set forth in its
most recent published annual report of condition.

         This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to
TIA Section 310(b).

SECTION 7.11      Preferential Collection of Claims Against Company.

         The Trustee is subject to TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

                                  ARTICLE VIII

                     SATISFACTION AND DISCHARGE; DEFEASANCE


SECTION 8.1       Satisfaction and Discharge of Indenture.

         This Indenture shall upon delivery of a written request of an Officer
of the Company to the Trustee cease to be of further effect with respect to the
Notes (except as to any surviving rights of registration of transfer or exchange
of Notes herein expressly provided for), and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture with respect to the Notes, when

                  (a) either

                           (i) all such Notes theretofore authenticated and
         delivered (other than (1) such Notes which have been destroyed, lost or
         stolen and which have been replaced or paid as provided in Section 2.7
         and (2) such Notes for whose payment money or Government Securities
         have theretofore been deposited in trust or segregated and held in
         trust by the Company and thereafter repaid to the Company or discharged
         from such trust, as provided in Section 8.9) have been delivered to the
         Trustee for cancellation; or

                           (ii) all such Securities not theretofore delivered to
         the Trustee for cancellation

                                    (A) have become due and payable, or

                                    (B) will become due and payable at their
                  final Stated Maturity within one year,

and the Company, in the case of (A) or (B) above, has deposited or caused to be
deposited with the Trustee as trust funds in trust for the purpose an amount of
money or Government Securities sufficient to pay and discharge the entire
indebtedness on such Notes not theretofore delivered to the Trustee for
cancellation, for principal and any premium and interest to the date of such
deposit (in the case of such Notes which have become due and payable) or to the
Stated Maturity of the principal of the Notes;

                  (b) the Company has paid or caused to be paid all other sums
payable hereunder by the Company with respect to such Notes; and


                                       49
   56

                  (c) the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of this
Indenture with respect to such Notes have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture with
respect to the Notes, the obligations of the Company to the Trustee under
Section 7.7 hereof, and, if money or Government Securities shall have been
deposited with the Trustee pursuant to subclause (ii) of clause (b) of this
Section, the obligations of the Company or Trustee under Section 8.2 hereof and
Section 8.9 shall survive.

SECTION 8.2       Application of Trust Money.

         Subject to the provisions of Section 8.9, all money and Government
Securities deposited with the Trustee pursuant to Section 8.1 hereof shall be
held in trust and applied by it, in accordance with the provisions of the Notes
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money or Government Securities has been
deposited with the Trustee.

SECTION 8.3       Option to Effect Legal Defeasance or Covenant Defeasance.

         The Company may, at the option of its Board of Directors evidenced by a
resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.4 or 8.5 hereof be applied to all outstanding Notes, upon
compliance with the conditions set forth in this Article VIII.

SECTION 8.4       Defeasance and Discharge.

         In addition to discharge of the Indenture pursuant to Section 8.1
hereof, the Company shall be deemed to have paid and discharged the entire
indebtedness on all the Notes on the date of the deposit referred to in clause
(a) of Section 8.6 hereof, and the provisions of this Indenture with respect to
the Notes shall no longer be in effect, (except as to (1) the rights of Holders
of such Notes to receive, solely from the trust fund described in Section 8.6
hereof and as more fully set forth in such Section, payments in respect of the
principal of and any premium and interest on such Notes when payments are due
(other than by acceleration), (2) the Company's obligations with respect to such
Notes under Sections 2.4, 2.6, 2.7, 2.10, 4.2 and 8.9 hereof, and (3) the
rights, powers, trusts, obligations, duties and immunities of the Trustee
hereunder), and the Trustee, at the expense of the Company, upon written request
of an Officer of the Company, shall execute proper instruments acknowledging the
same, if the applicable conditions set forth in Section 8.6 hereof are satisfied
("Defeasance"). For this purpose, such Defeasance means that the Company (and
any other obligor of the Notes) shall be deemed to have paid and discharged the
entire indebtedness represented by the Notes, which shall thereafter be deemed
to be "Outstanding" only for the purposes of Section 8.7 hereof and the rights
and obligations referred to in clauses (1) through (3) (inclusive) of this
Section 8.4, and to have satisfied all its other obligations under such Notes
and this Indenture insofar


                                       50
   57

as such Notes are concerned. Subject to compliance with this Article, the
Company may exercise its option (if any) to have this Section applied to any
Notes notwithstanding the prior exercise of its option (if any) to have Section
8.5 hereof applied to such Notes.

SECTION 8.5       Covenant Defeasance.

         The Company shall be released on the date of the deposit referred to in
clause (a) of Section 8.6 hereof from its obligations under Sections 4.6, 4.7
and 5.1 hereof, inclusive, on and after the date the applicable conditions set
forth in Section 8.6 hereof are satisfied ("Covenant Defeasance"); and the
occurrence of any event specified in clause (c) of Section 6.1 hereof (with
respect to any of Sections 4.6, 4.7 and 5.1 hereof, inclusive), shall be deemed
not to be or result in an Event of Default, in each case with respect to the
Notes. For this purpose, such Covenant Defeasance means that, with respect to
the Notes (i) the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such specified
Section, whether directly or indirectly by reason of any reference elsewhere
herein to any such Section or by reason of any reference in any Section to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or Event of Default under Section 6.1 hereof,
but, except as specified above, the remainder of this Indenture and such Notes
shall be unaffected thereby, and (ii) such Notes shall thereafter be deemed to
be not "Outstanding" for the purposes of any request, demand, authorization,
direction, notice, waiver, consent or declaration or other action of Holders
(and the consequences of any therefor) in connection with such specified
covenants, but shall continue to be deemed Outstanding for all other purposes
hereunder.

SECTION 8.6       Conditions to Defeasance or Covenant Defeasance.

         The following shall be the applicable conditions to the application of
Section 8.4 or Section 8.5 hereof to any Notes, as the case may be:

                  (a) The Company shall irrevocably have deposited or caused to
be deposited with the Trustee (or another trustee which satisfies the
requirements contemplated by Section 7.10 hereof and agrees to comply with the
provisions of this Article applicable to it) as trust funds in trust for the
purpose of making the following payments, specifically pledged as security for,
and dedicated solely to, the benefits of the Holders of such Notes, (A) money in
an amount, or (B) Government Securities which through the scheduled payment of
principal and interest in respect thereof in accordance with their terms will
provide, not later than one day before the due date of any payment, money in an
amount, or (C) a combination thereof, in each case sufficient, in the opinion of
a nationally recognized firm of independent public accountants expressed in a
written certificate thereof delivered to the Trustee, to pay the principal of
and any premium and interest on such Notes on the Stated Maturity of the
principal of the Notes in accordance with the terms of this Indenture and such
Notes.

                  (b) In order to have Section 8.4 hereof apply to any Notes, as
the case may be, the Company shall have delivered to the Trustee an Opinion of
Counsel stating that (A) the


                                       51
   58

Company has received from, or there has been published by, the Internal Revenue
Service a ruling or (B) since the date of this Indenture, there has been a
change in the applicable federal income tax law, in either case (A) or (B) to
the effect that, and based thereon such opinion shall confirm that, the Holders
of such Notes will not recognize gain or loss for federal income tax purposes as
a result of such deposit and Defeasance and will be subject to federal income
tax on the same amount, in the same manner and at the same times as would have
been the case if such deposit and Defeasance had not occurred.

                  (c) In order to have Section 8.5 hereof apply to any Notes, as
the case may be, the Company shall have delivered to the Trustee an Opinion of
Counsel to the effect that the Holders of such Notes will not recognize gain or
loss for federal income tax purposes as a result of such deposit and Covenant
Defeasance and will be subject to federal income tax on the same amount, in the
same manner and at the same times as would have been the case if such deposit
and Covenant Defeasance had not occurred.

                  (d) No Default or Event of Default with respect to such Notes
or any other Notes shall have occurred and be continuing at the time of such
deposit or, with regard to any such event specified in clauses (e) of (f) of
Section 6.1 hereof, at any time on or prior to the 90th day after the date of
such deposit (it being understood that this condition shall not be deemed
satisfied with respect to such specified events until after such 90th day).

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

                  (f) The Company shall have delivered to the Trustee an Opinion
of Counsel to the effect that on the 91st day following the deposit, the trust
funds will not be subject to avoidance under Section 547 of the Bankruptcy Code
or any successor provision thereof.

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

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


                                       52
   59
SECTION 8.7       Deposited Money and Government Securities to be Held in Trust;
                  Other Miscellaneous Provisions.

         Subject to Section 8.8 hereof, all money and Government Securities
(including the proceeds thereof) deposited with the Trustee or other qualifying
trustee (solely for purposes of this Section and Section 8.9 hereof, the Trustee
and any such other trustee are referred to collectively as the "Trustee")
pursuant to Section 8.6 hereof in respect of any Notes shall be held in trust
and applied by the Trustee, in accordance with the provisions of such Notes and
this Indenture, to the payment, either directly or through any such Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Notes for the payment or redemption of which
such finds have been deposited with the Trustee, of all sums due and to become
due thereon in respect of principal and any premiums and interest, but money so
held in trust need not be segregated from other funds except to the extent
required by law.

         Anything in this Article to the contrary notwithstanding, the Trustee
or the Paying Agent, as applicable, shall promptly return, deliver or pay to the
Company from time to time upon Company request any money or Government
Securities held by it as provided in Section 8.6 hereof with respect to any
Notes which, at any time, are in excess of the amount thereof which would then
be required to effect the Defeasance or Covenant Defeasance, as the case may be,
with respect to such Securities. The provisions of Section 8.8 hereof shall
apply to any money held by the Trustee or any Paying Agent under this Article
that remains unclaimed for two years after the Stated Maturity of the Notes for
which money or Government Securities have been deposited pursuant to Section 8.6
hereof.

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

SECTION 8.8       Repayment to Company.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of, and premium and
interest, if any, on, any Note and remaining unclaimed for two years after such
principal, premium or interest has become due and payable shall be paid to the
Company on its written request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter, as a
secured creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Company cause to be
published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such


                                       53
   60

notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

SECTION 8.9       Reinstatement.

         If the Trustee or Paying Agent is unable to apply any U.S. dollars or
non-callable Government Securities in accordance with Section 8.4 or 8.5 hereof,
as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.4 or 8.5 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.4 or 8.5 hereof,
as the case may be; provided, however, that, if the Company makes any payment of
principal of, or premium, if any, or interest on, any Note following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money held by the
Trustee or Paying Agent.

                                   ARTICLE IX

                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.1       Without Consent of Holders of Notes.

         Notwithstanding Section 9.2 hereof, the Company and the Trustee may
amend or supplement this Indenture or the Notes without the consent of Holders
of the Notes:

                  (a) to cure any ambiguity, defect or inconsistency;

                  (b) to provide for uncertificated Notes in addition to or in
place of certificated Notes or to alter the provisions of Article 2 hereof
(including the related definitions) in a manner that does not materially
adversely affect any Holder;

                  (c) to provide for the assumption of the Company's obligations
to the Holders of any of the Notes in the case of a merger, consolidation or
sale of assets of the Company pursuant to Article 5 hereof;

                  (d) to make any change that would provide any additional
rights or benefits to the Holders of the Notes or that does not adversely affect
the legal rights hereunder of any such Holder in any material respect; or

                  (e) to comply with requirements of the SEC in order to effect
or maintain the qualification of this Indenture under the TIA or to allow any
guarantor to guarantee the Notes.


                                       54
   61

         Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon receipt by the Trustee of the documents described in Section
9.6 hereof, the Trustee shall join with the Company in the execution of any
amended or supplemental Indenture authorized or permitted by the terms of this
Indenture and to make any further appropriate agreements and stipulations that
may be therein contained, but the Trustee shall not be obligated to enter into
such amended or supplemental Indenture that affects its own rights, duties,
liabilities or immunities under this Indenture or otherwise.

SECTION 9.2       With Consent of Holders of Notes.

         Except as provided below in this Section 9.2, the Company and the
Trustee may amend or supplement this Indenture and the Notes may be amended or
supplemented with the consent of the Holders of at least a majority in principal
amount of the Notes then outstanding (including, without limitation, consents
obtained in connection with a tender offer or exchange offer for the Notes),
and, subject to Sections 6.4 and 6.7 hereof, any existing Default or Event of
Default (other than a Default or Event of Default in the payment of the
principal of, or premium, if any, or interest on, the Notes, except a payment
default resulting from an acceleration that has been rescinded) or compliance
with any provision of this Indenture or the Notes may be waived with the consent
of the Holders of a majority in principal amount of the then outstanding Notes
(including consents obtained in connection with a tender offer or exchange offer
for the Notes).

         Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by
a Responsible Officer of the Trustee of the documents described in Section 9.6
hereof, the Trustee shall join with the Company in the execution of such amended
or supplemental Indenture.

         It shall not be necessary for the consent of the Holders of Notes under
this Section 9.2 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

         After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.4 and 6.7 hereof, the Holders of a
majority in aggregate principal amount of the Notes then outstanding may waive
compliance in a particular instance by the Company with any provision of this
Indenture or the Notes. However, without the consent of each Holder affected, an
amendment or waiver may not (with respect to any Notes held by a nonconsenting
Holder):


                                       55
   62



                  (a) change the Stated Maturity of the principal of, or any
installment of principal of or interest on, any such Note;

                  (b) reduce the principal amount of, or any interest on, any
such Note;

                  (c) reduce the amount of principal of any such Note payable
upon acceleration of the Stated Maturity thereof;

                  (d) change the place or currency of payment of principal of,
or interest on, any such Note;

                  (e) impair the right to institute suit for the enforcement of
any payment on or with respect to any such Note;

                  (f) reduce the percentage in principal amount of such Note,
the consent of whose Holders is required for modification or amendment of the
Indenture;

                  (g) reduce the percentage in principal amount of such Note
necessary for waiver of compliance with certain provisions of the Indenture or
for waiver of certain defaults;

                  (h) modify such provisions with respect to modification and
waiver;

                  (i) waive, reduce or modify a Make-Whole Premium payable with
respect to any Note called for redemption; or

                  (j) make any change in Section 6.4 or 6.7 hereof or in the
foregoing amendment and waiver provisions.

SECTION 9.3       Compliance with Trust Indenture Act.

         Every amendment or supplement to this Indenture or the Notes shall be
set forth in a amended or supplemental Indenture that complies with the TIA as
then in effect.

SECTION 9.4       Revocation and Effect of Consents.

         Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note, even if notation of the consent is not
made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.


                                       56
   63

SECTION 9.5       Notation on or Exchange of Notes.

         The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company, in
exchange for all Notes, may issue and the Trustee shall authenticate new Notes
that reflect the amendment, supplement or waiver.

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

SECTION 9.6       Trustee to Sign Amendments, Etc.

         The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Trustee
may, but shall not be obligated to, enter into any such supplemental indenture
which affects the Trustee's own rights, duties, liabilities or immunities under
this Indenture or otherwise. The Company may not sign an amendment or
supplemental Indenture until the Board of Directors approves it. In executing
any amended or supplemental indenture, the Trustee shall be entitled to receive
and (subject to Section 7.1 hereof) shall be fully protected in relying upon, an
Officers' Certificate and an Opinion of Counsel stating that the execution of

Indenture.

SECTION 9.7       Record Dates.

         Except as otherwise provided in this Indenture or the Notes, the
Company will be entitled to set any day as a record date for the purpose of
determining the Holders of Notes entitled to give or take any direction, notice,
consent, waiver or other action under the Indenture. Pursuant to Section 6.10,
the Trustee also will be entitled to set a record date for certain action by
Holders of Notes. If a record date is set for any action to be taken by Holders
of the Notes, such action may be taken only by persons who are Holders of the
Notes on the record date. To be effective, such action must be taken by Holders
of the requisite principal amount of the Notes within a specified period
following the record date. For any particular record date, this period will be
180 days or such shorter period as may be specified by the Company (or the
Trustee, if it sets the record date), and may be shortened or lengthened (but
not beyond 180 days) from time to time.

                 [Insert the Global Note Legend, if applicable,

              [Insert the Private Placement Legend, if applicable,
                  pursuant to the provisions of the Indenture]

         Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

         1. Interest. National-Oilwell, Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at 6
7/8% per annum, from June 26, 1998 until maturity [and shall pay any additional
interest payable on the principal amount of this Note pursuant to Section 2.5 of
the Registration Rights Agreement referred to below.]** The Company will pay
interest semi-annually in arrears on January 1 and July 1 of each year, or if
any such day is not a Business Day, on the next succeeding Business Day (each an
"Interest Payment Date"). Interest on the Notes will accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from the
date of issuance; provided that if there is no existing Default in the payment
of interest, and if this Note is authenticated between a record date referred to
on the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; provided, further, that
the first Interest Payment Date shall be January 1, 1999. The Company shall pay
interest on overdue principal and premium, if any, from time to time as provided
in Section 2.12 of the Indenture at the rate borne on the Notes; it shall pay
interest on overdue installments of interest (without regard to any applicable
grace periods) from time to time as provided in Section 2.12 of the Indenture at
the same rate to the extent lawful. Interest will be computed on the basis of a
360-day year of twelve 30-day months.

         2. Method of Payment. The Company will pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders of Notes
at the close of business on the December 15 or June 15 next preceding the
Interest Payment Date, even if such Notes are canceled after such record date
and on or before such Interest Payment Date, except as provided in Section 2.12
of the Indenture with respect to defaulted interest. The Notes will be payable
as to principal, premium, if any, and interest at the office or agency of the
Company maintained for such purpose within the City and State of New York, or,
at the option of the Company, payment of interest may be made by check mailed to
the Holders at their addresses set forth in the register of Holders, and
provided that payment by wire transfer of immediately available funds will be
required with respect to principal of and interest and premium, if any, on, all
Global Notes and all other Notes the Holders of which shall have provided wire
transfer instructions to the Company or the Paying Agent. Such payment shall be
in such coin or currency of the United States of America as at the time of
payment is legal tender for payment of public and private debts.

         3. Paying Agent and Registrar. Initially, The Bank of New York, the
Trustee under the Indenture, will act as Paying Agent and Registrar. The Company
may change any Paying Agent or Registrar without notice to any Holder. The
Company or any of its Subsidiaries may act in any such capacity.

         4. Indenture. The Company issued the Notes under an Indenture dated as
of June 26, 1998 ("Indenture") between the Company and the Trustee. The terms of
the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code Sections 77aaa-77bbbb). The Notes are subject to all such terms, and
Holders are referred to the Indenture and such Act for a statement of such
terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be
controlling. The Notes are obligations of the Company limited to $150,000,000 in
aggregate principal amount.

         5. Optional Redemption.

         The Notes are redeemable prior to their Stated Maturity, at the option
of the Company, at any time in whole or from time to time in part, on any date
prior to their final Stated Maturity selected by the Company (the "Redemption
Date") at a price equal to 100% of the principal amount thereof plus accrued and
unpaid interest, if any, to the Redemption Date (subject to the right of Holders
on the relevant record date to receive interest due on an Interest Payment Date
that is on or prior to the Redemption Date) plus the Make-Whole Premium (as
defined in the Indenture), if any (the "Redemption Price"). In no event will the
Redemption Price ever be less than 100% of the principal amount of the Notes
plus accrued interest to the Redemption Date.

         6. Mandatory Redemption. The Company shall not be required to make
mandatory redemption payments with respect to the Notes.

         7. Notice of Redemption. Notice of redemption will be mailed at least
30 days but not more than 60 days before the Redemption Date to each Holder
whose Notes are 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, unless all of the Notes held by a Holder are to be redeemed. On and
after the Redemption Date, interest ceases to accrue on Notes or portions
thereof called for redemption.

         8. Denominations, Transfer, Exchange. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, it need not
exchange or register the transfer of any Notes for a period of 15


                                      A1-3
   72

days before the mailing of a notice of redemption of Notes to be redeemed or
during the period between a record date and the corresponding Interest Payment
Date.

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

         10. Amendment, Supplement and Waiver. Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Notes, and any existing default or compliance with any provision of the
Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes. Without the consent
of any Holder of a Note, the Indenture or the Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes or to
alter the provisions in Article 2 of the Indenture in a manner that does not
materially adversely affect any Holder, to provide for the assumption of the
Company's obligations to Holders of the Notes in case of a merger, consolidation
or sale of assets in accordance with Article 5 of the Indenture, to make any
change that would provide any additional rights or benefits to the Holders of
the Notes or that does not adversely affect the legal rights under the Indenture
of any such Holder in any material respect, or to comply with the requirements
of the SEC in order to effect or maintain the qualification of the Indenture
under the TIA or to allow any guarantor to guarantee the Notes.

         11. Defaults and Remedies. Events of Default include: (a) default in
the payment when due of principal of, or Make-Whole Premium, if any, on, the
Notes; (b) default in the payment when due of interest on the Notes and such
default continues for a period of 30 days; (c) failure by the Company or any of
its Restricted Subsidiaries to observe or perform any other covenant (other than
the covenants described in (a) and (b) above) in the Indenture or the Notes for
60 days after notice to the Company by the Trustee or the Holders of at least
25% in aggregate principal amount of the Notes then outstanding; (d) failure by
the Company or any Subsidiary to pay indebtedness when due within the applicable
grace period, if any, or the acceleration of such indebtedness by the holders
thereof and, in either case, the principal amount of such unpaid or accelerated
indebtedness exceeds $20 million; or (e) certain events of bankruptcy or
insolvency with respect to the Company or any of its Significant Subsidiaries as
specified in Section 6.1 of the Indenture. If any Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Notes by notice to the Company may declare all the Notes to
be due and payable immediately. Notwithstanding the foregoing, in the case of an
Event of Default arising from certain events of bankruptcy or insolvency, the
principal amount of all then outstanding Notes will become due and payable
without further action or notice. Holders may not enforce the Indenture or the
Notes except as provided in the Indenture. Subject to certain limitations,
Holders of a majority in principal amount of the then outstanding Notes may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of
principal, premium, if any, or interest) if it determines that withholding
notice is in their interest. The Holders of a majority in aggregate principal
amount of the Notes then outstanding by notice to the Trustee may on behalf of


                                      A1-4
   73

the Holders of all of the Notes waive any existing Default or Event of Default
and its consequences under the Indenture except a continuing Default or Event of
Default in the payment of interest or premium, if any, on, or the principal of,
the Notes or in respect of any other covenant or provision of the Indenture
which, under Section 9.2 of the Indenture, cannot be modified without the
consent of the Holder of each outstanding Note. The Company is required to
deliver to the Trustee annually a statement regarding compliance with the
Indenture, and the Company is required upon becoming aware of any Default or
Event of Default, to deliver to the Trustee a statement specifying such Default
or Event of Default.

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

         13. No Recourse Against Others. A director, officer, employee,
incorporator, partner, member or stockholder of the Company or any Subsidiary of
the Company, as such, 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.

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

         15. Abbreviations. Customary abbreviations may be used in the name of a
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 Act).

         16. 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 CUSIP numbers will be used 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.

         [17. Additional Rights of Holders of Restricted Global Notes and
Restricted Definitive Notes. In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of June 26, 1998, between the Company and the parties named
on the signature pages thereof (the "Registration Rights Agreement").]**

Code Sections 77aaa-77bbbb). The Notes are subject to all such terms, and
Holders are referred to the Indenture and such Act for a statement of such
terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be
controlling. The Notes are obligations of the Company limited to $150,000,000 in
aggregate principal amount.

         5. Optional Redemption. The Notes are redeemable prior to their final
Stated Maturity, at the option of the Company, at any time in whole or from time
to time in part, on any date prior to their Stated Maturity selected by the
Company (the "Redemption Date") at a price equal to 100% of the principal amount
thereof plus accrued and unpaid interest, if any, to the Redemption Date
(subject to the right of Holders on the relevant record date to receive interest
due on an Interest Payment Date that is on or prior to the Redemption Date) plus
the Make-Whole Premium (as defined in the Indenture), if any (the "Redemption
Price") . In no event will the Redemption Price ever be less than 100% of the

things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, it need not
exchange or register the transfer of any Notes for a period of 15 days before
the mailing of a notice of redemption of Notes to be redeemed or during the
period between a record date and the corresponding Interest Payment Date.

         This Regulation S Temporary Global Note is exchangeable in whole or in
part for one or more Global Notes only (i) on or after the termination of the
40-day restricted period (as defined in Regulation S) and (ii) upon presentation

Regulation S Temporary Global Note.

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

         10. Amendment, Supplement and Waiver. Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Notes, and any existing default or compliance with any provision of the
Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes. Without the consent
of any Holder of a Note, the Indenture or the Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes or to
alter the provisions in Article 2 of the Indenture in a manner that does not
materially adversely affect any Holder, to provide for the assumption of the
Company's obligations to Holders of the Notes in case of a merger, consolidation
or sale of assets in accordance with Article 5 of the Indenture, to make any
change that would provide any additional rights or benefits to the Holders of
the Notes or that does not adversely affect the legal rights under the Indenture
of any such Holder in any material respect, or to comply with the requirements
of the SEC in order to effect or maintain the qualification of the Indenture
under the TIA or to allow any guarantor to guarantee the Notes.

         11. Defaults and Remedies. Events of Default include: (a) default in
the payment when due of principal of, or Make-Whole Premium, if any, on, the
Notes; (b) default in the payment when due of interest on the Notes and such
default continues for a period of 30 days; (c) failure by the Company or any of
its Restricted Subsidiaries to observe or perform any other covenant (other than
the covenants described in (a) and (b) above) in the Indenture or the Notes for
60 days after notice to the Company by the Trustee or the Holders of at least
25% in aggregate principal amount of the Notes then outstanding; (d) failure by
the Company or any Subsidiary to pay indebtedness when due within the applicable
grace period, if any, or the acceleration of such indebtedness by the holders
thereof and, in either case, the principal amount of such unpaid or accelerated
indebtedness exceeds $20 million; or (e) certain events of bankruptcy or
insolvency with respect to the Company or any of its Significant Subsidiaries as
specified in Section 6.1 of the Indenture. If any Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Notes by notice to the Company may declare all the Notes to
be due and payable immediately. Notwithstanding the foregoing, in the case of an
Event of Default arising from certain events of bankruptcy or insolvency, the
principal amount of all then outstanding Notes will become due and payable
without further action or notice. Holders may not enforce the Indenture or the
Notes except as provided in the Indenture. Subject to certain limitations,
Holders of a majority in principal amount of the then outstanding Notes may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of
principal, premium, if any, or interest) if it determines that withholding
notice is in their interest. The Holders of a majority in aggregate principal
amount of the Notes then outstanding by notice to the Trustee may on behalf of


                                      A2-6
   83

the Holders of all of the Notes waive any existing Default or Event of Default
and its consequences under the Indenture except a continuing Default or Event of
Default in the payment of interest or premium, if any, on, or the principal of,
the Notes or in respect of any other covenant or provision of the Indenture
which, under Section 9.2 of the Indenture, cannot be modified without the
consent of the Holder of each outstanding Note. The Company is required to
deliver to the Trustee annually a statement regarding compliance with the
Indenture, and the Company is required upon becoming aware of any Default or
Event of Default, to deliver to the Trustee a statement specifying such Default
or Event of Default.

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

         13. No Recourse Against Others. A director, officer, employee,
incorporator, partner, member or stockholder of the Company or any Subsidiary of
the Company, as such, 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.

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

         15. Abbreviations. Customary abbreviations may be used in the name of a
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 Act).

         16. 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 CUSIP numbers will be used 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.

         17. [Additional Rights of Holders of Restricted Global Notes and
Restricted Definitive Notes. In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of June 26, 1998, between the Company and the parties named
on the signature pages thereof (the "Registration Rights Agreement").]**

charge a copy of the Indenture [and/or the Registration Rights Agreement.]**

2.       (i)(A) any purchase of the Notes by us will be for our own account or
         for the account of one or more other institutional accredited investors
         or as fiduciary for the account of one or more trusts, each of which is
         an "accredited investor" within the meaning of Rule 501(a)(7) under the
         Securities Act and for each of which we exercise sole investment
         discretion or (B) we are a "bank," within the meaning of Section

         other institution described in Section 3(a)(5)(A) of the Securities Act

3.       in the event that we purchase any Notes, we will acquire Notes having
         a minimum purchase price of not less than $250,000 for our own account
         and for each separate account for which we are acting;

4.       we have such knowledge and experience in financial and business
         matters that we are capable of evaluating the merits and risks of
         purchasing Notes;

5.       we are not acquiring the Notes with a view to any distribution
         thereof in a transaction that would violate the Securities Act or the
         securities laws of any State of the United States or any other
         applicable jurisdictions, provided that the disposition of our property
         and the property of any accounts for which we are acting as fiduciary
         shall remain at all times within our control;

6.       we have received a copy of the Offering Memorandum relating to the
         offering of the Notes and acknowledge that we have had access to such
         financial and other information, and have been afforded the opportunity
         to ask such questions of representatives of the Company and receive
         answers thereto, as we deem necessary in connection with our decision
         to purchase the Notes; and

7.       (vii)(a) we are not an employee benefit plan or other arrangement that
         is subject to the Employee Retirement Income Security Act of 1974, as
         amended, or Section 4975 of the Internal Revenue Code of 1986, as
         amended, or an entity whose underlying assets include assets of such a
         plan or arrangement (pursuant to 29 C.F.R. Section 2510.3-101 or
         otherwise), and we are not purchasing (and will not hold) the Notes on
         behalf of, or with the assets of, any such plan, arrangement or entity;
         or (b) our purchase and holding of the Notes are completely covered by
         the full exemptive relief provided by U.S. Department of Labor
         Prohibited Transaction Class Exemption 96-23, 95-60, 91-38, 90-1 or
         84-14.

                  We understand that the Notes are being offered in a
transaction not involving any public offering within the meaning of the
Securities Act and that the Notes have not been registered under the Securities
Act, and we agree, on our own behalf, and on behalf of each account for which we
acquire any Notes, that if in the future we decide to resell or otherwise
transfer such Notes, such Notes will not be offered, sold or otherwise
transferred prior to (x) the date that is two years (or such shorter period of
time as permitted by Rule 144(k) under the Securities Act or any successor
provision thereunder) after the later of the original issue date hereof (or any
predecessor of this Note) and the last day on which National-Oilwell, Inc. (the
"Company") or any affiliate of the Company was the owner of the Note (or any
predecessor of this security) and (y) such later date, if any, as may be
required by applicable laws (the "Resale Restriction Termination Date"), except
(a) to the Company or a subsidiary thereof, (b) pursuant to an effective
registration statement under the Securities Act, (c) for so long as the Note is
eligible for resale pursuant to Rule 144A under the Securities Act ("Rule
144A"), to a person it reasonably believes is a "qualified institutional buyer"
as defined in Rule 144A that is acquiring the Note for its own account or for
the account of a qualified institutional buyer to whom notice is given that the
transfer is being made in reliance on Rule 144A, (d) to an institutional
"accredited investor" (as defined in Rule 501(a)(1), (2), (3) or (7) under the
Securities Act) (an "institutional accredited investor") that, prior to such
transfer, furnishes to the trustee a signed letter containing certain
representations relating to restrictions on transfer of


                                       D-2

the Note (the form of which letter can be obtained from the Trustee), (e)
pursuant to offers and sales to non-U.S. Persons that occur in an "offshore
transaction" within the meaning of Regulation S under the Securities Act, or (f)
pursuant to another available exemption from the registration requirements of
the Securities Act; provided that the Company, the Trustee, the transfer agent
and the registrar shall have the right prior to any such offer, sale or transfer
(i) pursuant to clause (c), (d), (e) or (f) to require the delivery of an
opinion of counsel, certification and/or other information satisfactory to each
of them, and (ii) in each of the foregoing cases, to require that a certificate
of transfer in the form appearing on the Note is completed and delivered by the
transferor to the Trustee. We further agree to provide any person purchasing any
of the Notes other than pursuant to clause (b) above from us a notice advising
such purchaser that resales of the Notes are restricted as stated above. We
understand that the registrar and transfer agent for the Notes will not be
required to accept for registration of transfer any Notes, except upon
presentation of evidence satisfactory to the Company that the foregoing
restrictions on transfer have been complied with. We further understand that any
Notes that we receive in the form of physical certificates will bear a legend
reflecting the substance of this paragraph.
