Merrill Lynch, Pierce, Fenner & Smith
 Incorporated
c/o J.P. Morgan Securities Inc.
270 Park Avenue, 4th floor
New York, New York  10017

Ladies and Gentlemen:

          Mission Resources Corporation, a Delaware corporation (the "Company"),
proposes to issue and sell to J.P. Morgan Securities Inc. ("JPMorgan") and
Merrill Lynch, Pierce, Fenner & Smith Incorporated (together with JPMorgan, the
"Initial Purchasers") upon the terms and subject to the conditions set forth in
a purchase agreement dated May 23, 2001 (the "Purchase Agreement"), $125,000,000
aggregate principal amount of its 10 7/8% Senior Subordinated Notes due 2007
Series B (the "Securities") to be jointly and severally guaranteed (the
"Guarantees") by the subsidiaries of the Company listed on Schedule 1 and the
signatories hereto (collectively, the "Guarantors").  Capitalized terms used but
not defined herein shall have the meanings given to such terms in the Purchase
Agreement.

          As an inducement to the Initial Purchasers to enter into the Purchase
Agreement and in satisfaction of a condition to the obligations of the Initial
Purchasers thereunder, the Company and the Guarantors agree with the Initial
Purchasers, for the benefit of the holders (including the Initial Purchasers) of
the Securities, the Exchange Securities (as defined herein) and the Private
Exchange Securities (as defined herein) (collectively, the "Holders"), as
follows:

          1.  Registered Exchange Offer.  The Company shall (i) prepare and, not
later than 90 days following the date of original issuance of the Securities
(the "Issue Date"), file with the Commission a registration statement (the
"Exchange Offer Registration Statement") on an appropriate form under the
Securities Act with respect to a proposed offer to the Holders of the Securities
and the Guarantees (the "Exchange Offer") to issue and deliver to such Holders,
in exchange for the Securities and the Guarantees, a like aggregate principal
amount of debt securities of the Company and guarantees thereof by the
Guarantors (the "Exchange Securities") that are identical in all material
respects to the Securities, except for the transfer restrictions
<PAGE>

relating to the Securities, (ii) use its reasonable best efforts to cause the
Exchange Offer Registration Statement to become effective under the Securities
Act no later than 150 days after the Issue Date and the Exchange Offer to be
consummated no later than 180 days after the Issue Date and (iii) keep the
Exchange Offer Registration Statement effective for not less than 20 business
days (or longer, if required by applicable law) after the date on which notice
of the Exchange Offer is mailed to the Holders (such period being called the
"Exchange Offer Registration Period"). The Exchange Securities will be issued
under the Indenture or an indenture (the "Exchange Securities Indenture")
between the Company, the Guarantors and the Trustee or such other bank or trust
company that is reasonably satisfactory to the Initial Purchasers, as trustee
(the "Exchange Securities Trustee"), such indenture to be identical in all
material respects to the Indenture, except for the transfer restrictions
relating to the Securities (as described above).

          Upon the effectiveness of the Exchange Offer Registration Statement,
the Company shall promptly commence the Exchange Offer, it being the objective
of such Exchange Offer to enable each Holder electing to exchange Securities for
Exchange Securities (assuming that such Holder (a) is not an affiliate of the
Company or an Exchanging Dealer (as defined herein) not complying with the
requirements of the next sentence, (b) is not an Initial Purchaser holding
Securities that have, or that are reasonably likely to have, the status of an
unsold allotment in an initial distribution, (c) acquires the Exchange
Securities in the ordinary course of such Holder's business and (d) has no
arrangements or understandings with any person to participate in the
distribution of the Exchange Securities) and to trade such Exchange Securities
from and after their receipt without any limitations or restrictions under the
Securities Act and without material restrictions under the securities laws of
the several states of the United States.  The Company, the Guarantors, the
Initial Purchasers and each Exchanging Dealer acknowledge that, pursuant to
current interpretations by the Commission's staff of Section 5 of the Securities
Act, each Holder that is a broker-dealer electing to exchange Securities,
acquired for its own account as a result of market-making activities or other
trading activities, for Exchange Securities (an "Exchanging Dealer"), is
required to deliver a prospectus containing substantially the information set
forth in Annex A hereto on the cover, in Annex B hereto in the "Exchange Offer
Procedures" section and the "Purpose of the Exchange Offer" section and in Annex
C hereto in the "Plan of Distribution" section of such prospectus in connection
with a sale of any such Exchange Securities received by such Exchanging Dealer
pursuant to the Exchange Offer.

          If, prior to the consummation of the Exchange Offer, any Holder holds
any Securities acquired by it that have, or that are reasonably likely to be
determined to have, the status of an unsold allotment in an initial
distribution, or any Holder is not entitled to participate in the Exchange
Offer, the Company shall, upon the request of any such Holder, simultaneously
with the delivery of the Exchange Securities in the Exchange Offer, issue and
deliver to any such Holder, in exchange for the Securities held by such Holder
(the "Private Exchange"), a like aggregate principal amount of debt securities
of the Company  and guarantees thereof by the Guarantors (the "Private Exchange
Securities") that are identical in all material respects to the Exchange
Securities, except for the transfer restrictions relating to such Private
Exchange Securities.  The Private Exchange Securities will be issued under the
same indenture as the

                                       2
<PAGE>

Exchange Securities, and the Company shall use its reasonable best efforts to
cause the Private Exchange Securities to bear the same CUSIP number as the
Exchange Securities.

          In connection with the Exchange Offer, the Company shall:

                (a) mail to each Holder a copy of the prospectus forming part of
             the Exchange Offer Registration Statement, together with an
             appropriate letter of transmittal and related documents;

                (b) keep the Exchange Offer open for not less than 20 business
             days (or longer, if required by applicable law) after the date on
             which notice of the Exchange Offer is mailed to the Holders;

                (c) utilize the services of a depositary for the Exchange Offer
             with an address in the Borough of Manhattan, The City of New York;

                (d) permit Holders to withdraw tendered Securities at any time
             prior to the close of business, New York City time, on the last
             business day on which the Exchange Offer shall remain open; and

                (e) otherwise comply in all respects with all laws that are
             applicable to the Exchange Offer.

          As soon as practicable after the close of the Exchange Offer and any
Private Exchange, as the case may be, the Company shall:

                (a) accept for exchange all Securities tendered and not validly
             withdrawn pursuant to the Exchange Offer and the Private Exchange;

                (b) deliver to the Trustee for cancellation all Securities so
             accepted for exchange; and

                (c) cause the Trustee or the Exchange Securities Trustee, as the
             case may be, promptly to authenticate and deliver to each Holder,
             Exchange Securities or Private Exchange Securities, as the case may
             be, equal in principal amount to the Securities of such Holder so
             accepted for exchange.

          The Company shall use its reasonable best efforts to keep the Exchange
Offer Registration Statement effective and to amend and supplement the
prospectus contained therein in order to permit such prospectus to be used by
all persons subject to the prospectus delivery requirements of the Securities
Act for such period of time as such persons must comply with such requirements
in order to resell the Exchange Securities; provided that (i) in the case where
such prospectus and any amendment or supplement thereto must be delivered by an
Exchanging Dealer, such period shall be the lesser of 180 days and the date on
which all Exchanging Dealers have sold all Exchange Securities held by them and
(ii) the Company shall make such prospectus

                                       3
<PAGE>

and any amendment or supplement thereto available to any broker-dealer for use
in connection with any resale of any Exchange Securities for a period of not
less than 180 days after the consummation of the Exchange Offer.

          The Indenture or the Exchange Securities Indenture, as the case may
be, shall provide that the Securities, the Exchange Securities and the Private
Exchange Securities shall vote and consent together on all matters as one class
and that none of the Securities, the Exchange Securities or the Private Exchange
Securities will have the right to vote or consent as a separate class on any
matter.

          Interest on each Exchange Security and Private Exchange Security
issued pursuant to the Exchange Offer and in the Private Exchange will accrue
from the last interest payment date on which interest was paid on the Securities
surrendered in exchange therefor or, if no interest has been paid on the
Securities, from the Issue Date.

          Each Holder participating in the Exchange Offer shall be required to
represent to the Company that at the time of the consummation of the Exchange
Offer (i) any Exchange Securities received by such Holder will be acquired in
the ordinary course of business, (ii) such Holder will have no arrangements or
understanding with any person to participate in the distribution of the
Securities or the Exchange Securities within the meaning of the Securities Act
and (iii) such Holder is not an affiliate of the Company or, if it is such an
affiliate, such Holder will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable.

          Notwithstanding any other provisions hereof, the Company will ensure
that (i) any Exchange Offer Registration Statement and any amendment thereto and
any prospectus forming part thereof and any supplement thereto complies in all
material respects with the Securities Act and the rules and regulations of the
Commission thereunder, (ii) any Exchange Offer Registration Statement and any
amendment thereto does not, when it becomes effective, contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading and
(iii) any prospectus forming part of any Exchange Offer Registration Statement,
and any supplement to such prospectus, does not, as of the consummation of the
Exchange Offer, include an untrue statement of a material fact or omit to state
a material fact necessary in order to make the statements therein, in the light
of the circumstances under which they were made, not misleading.

          2.  Shelf Registration.  If (i) because of any change in law or
applicable interpretations thereof by the Commission's staff the Company is not
permitted to effect the Exchange Offer as contemplated by Section 1 hereof, or
(ii) for any other reason the Exchange Offer is not consummated within 180 days
after the Issue Date, or (iii) any Initial Purchaser so requests with respect to
Securities or Private Exchange Securities not eligible to be exchanged for
Exchange Securities in the Exchange Offer and held by it following the
consummation of the Exchange Offer, or (iv) any applicable law or
interpretations do not permit any Holder to participate in the Exchange Offer,
or (v) any Holder that participates in the Exchange Offer does

                                       4
<PAGE>

not receive freely transferable Exchange Securities in exchange for tendered
Securities, or (vi) the Company so elects, then the following provisions shall
apply:

                (a) The Company and the Guarantors shall use their reasonable
             best efforts to file as promptly as practicable (but in no event
             more than the later of 45 days after so required or requested
             pursuant to this Section 2 or 90 days after the Issue Date) with
             the Commission (the "Shelf Filing Date"), and thereafter shall use
             their reasonable best efforts to cause to be declared effective, a
             shelf registration statement on an appropriate form under the
             Securities Act relating to the offer and sale of the Transfer
             Restricted Securities (as defined below) by the Holders thereof
             from time to time in accordance with the methods of distribution
             set forth in such registration statement (hereafter, a "Shelf
             Registration Statement" and, together with any Exchange Offer
             Registration Statement, a "Registration Statement").

                (b) The Company and the Guarantors shall use their reasonable
             best efforts to keep the Shelf Registration Statement continuously
             effective in order to permit the prospectus forming part thereof to
             be used by Holders of Transfer Restricted Securities for a period
             ending on the earlier of (i) two years from the Issue Date or such
             shorter period that will terminate when all the Transfer Restricted
             Securities covered by the Shelf Registration Statement have been
             sold pursuant thereto and (ii) the date on which the Securities
             become eligible for resale without volume restrictions pursuant to
             Rule 144 under the Securities Act (in any such case, such period
             being called the "Shelf Registration Period"). The Company and the
             Guarantors shall be deemed not to have used their reasonable best
             efforts to keep the Shelf Registration Statement effective during
             the requisite period if they voluntarily take any action that would
             result in Holders of Transfer Restricted Securities covered thereby
             not being able to offer and sell such Transfer Restricted
             Securities during that period, unless such action is required by
             applicable law.

                (c) Notwithstanding any other provisions hereof, the Company
             will ensure that (i) any Shelf Registration Statement and any
             amendment thereto and any prospectus forming part thereof and any
             supplement thereto complies in all material respects with the
             Securities Act and the rules and regulations of the Commission
             thereunder, (ii) any Shelf Registration Statement and any amendment
             thereto (in either case, other than with respect to information
             included therein in reliance upon or in conformity with written
             information furnished to the Company by or on behalf of any Holder
             specifically for use therein (the "Holders' Information")) does not
             contain an untrue statement of a material fact or omit to state a
             material fact required to be stated therein or necessary to make
             the statements therein not misleading and (iii) any prospectus
             forming part of any Shelf Registration Statement, and any
             supplement to such prospectus (in either case, other than with
             respect to Holders' Information), does not include an untrue
             statement of a material fact or omit to state a material fact
             necessary in order to make the statements therein, in the light of
             the circumstances under which they were made, not misleading.

                (d) In the absence of the events described in clauses (i)
             through (vi) of the first paragraph of this Section 2, the Company
             and the Guarantors shall not be permitted to discharge its
             obligations hereunder by means of the filing of a Shelf
             Registration Statement.

                                       5
<PAGE>

          3.  Additional Interest.  (a) The parties hereto agree that the
Holders of Transfer Restricted Securities will suffer damages if the Company and
the Guarantors fail to fulfill their obligations under Section 1 or Section 2,
as applicable, and that it would not be feasible to ascertain the extent of such
damages. Accordingly, if (i) the Exchange Offer Registration Statement is not
filed with the Commission on or prior to 90 days after the Issue Date or the
Shelf Registration Statement is not filed with the Commission on or before the
Shelf Filing Date, (ii) the Exchange Offer Registration Statement is not
declared effective within 150 days after the Issue Date or the Shelf
Registration Statement is not declared effective within 60 days of the Shelf
Filing Date, (iii) the Exchange Offer is not consummated on or prior to 180 days
after the Issue Date, or (iv) the Shelf Registration Statement is filed and
declared effective within 60 days after the Shelf Filing Date but shall
thereafter cease to be effective (at any time that the Company and the
Guarantors are obligated to maintain the effectiveness thereof) without being
succeeded within 30 days by an additional Registration Statement filed and
declared effective (each such event referred to in clauses (i) through (iv), a
"Registration Default"), the Company and the Guarantors will be jointly and
severally obligated to pay additional interest to each Holder of Transfer
Restricted Securities, during the period of one or more such Registration
Defaults, in an amount equal to $ 0.192 per week per $1,000 principal amount of
Transfer Restricted Securities held by such Holder until (i) the applicable
Registration Statement is filed, (ii) the Exchange Offer Registration Statement
is declared effective and the Exchange Offer is consummated, (iii) the Shelf
Registration Statement is declared effective or (iv) the Shelf Registration
Statement again becomes effective, as the case may be. Following the cure of all
Registration Defaults, the accrual of additional interest will cease. As used
herein, the term "Transfer Restricted Securities" means each Security or Private
Exchange Security until the earliest to occur of: (i) the date on which such
Security has been exchanged for a freely transferable Exchange Security in the
Exchange Offer, (ii) the date on which such Security or Private Exchange
Security has been effectively registered under the Securities Act and disposed
of in accordance with the Shelf Registration Statement or (iii) the date on
which such Security or Private Exchange Security is distributed to the public
pursuant to Rule 144 under the Securities Act or is saleable pursuant to Rule
144(k) under the Securities Act. Notwithstanding anything to the contrary in
this Section 3(a), neither the Company nor the Guarantors shall be required to
pay additional interest to a Holder of Transfer Restricted Securities if such
Holder failed to comply with its obligations to make the representations set
forth in the second to last paragraph of Section 1 or failed to provide the
information required to be provided by it, if any, pursuant to Section 4(n).

          (b) The Company shall notify the Trustee and the Paying Agent under
the Indenture immediately upon the happening of each and every Registration
Default. The Company and the Guarantors shall pay the additional interest due on
the Transfer Restricted Securities by depositing with the Paying Agent (which
may not be the Company for these purposes), in trust, for the benefit of the
Holders thereof, prior to 10:00 a.m., New York City time, on the next interest
payment date specified by the Indenture and the Securities, sums sufficient to
pay the additional interest then due. The additional interest due shall be
payable on each interest payment date specified by the Indenture and the
Securities to the record holder entitled to receive the interest payment to be
made on such date. Each obligation to pay

                                       6
<PAGE>

additional interest shall be deemed to accrue from and including the date of the
applicable Registration Default.

          (c) The parties hereto agree that the additional interest provided for
in this Section 3 constitute a reasonable estimate of and are intended to
constitute the sole damages that will be suffered by Holders of Transfer
Restricted Securities by reason of the failure of (i) the Shelf Registration
Statement or the Exchange Offer Registration Statement to be filed, (ii) the
Shelf Registration Statement to remain effective or (iii) the Exchange Offer
Registration Statement to be declared effective and the Exchange Offer to be
consummated, in each case to the extent required by this Agreement.

          4.  Registration Procedures.  In connection with any Registration
Statement, the following provisions shall apply:

          (a) The Company shall (i) furnish to each Initial Purchaser, prior to
the filing thereof with the Commission, a copy of the Registration Statement and
each amendment thereof and each supplement, if any, to the prospectus included
therein and shall use its reasonable best efforts to reflect in each such
document, when so filed with the Commission, such comments as any Initial
Purchaser may reasonably propose; (ii) include the information set forth in
Annex A hereto on the cover, in Annex B hereto in the "Exchange Offer
Procedures" section and the "Purpose of the Exchange Offer" section and in Annex
C hereto in the "Plan of Distribution" section of the prospectus forming a part
of the Exchange Offer Registration Statement, and include the information set
forth in Annex D hereto in the Letter of Transmittal delivered pursuant to the
Exchange Offer; and (iii) if requested by any Initial Purchaser, include the
information required by Items 507 or 508 of Regulation S-K, as applicable, in
the prospectus forming a part of the Exchange Offer Registration Statement.

          (b) The Company shall advise each Initial Purchaser, each Exchanging
Dealer and the Holders (if applicable) and, if requested by any such person,
confirm such advice in writing (which advice pursuant to clauses (ii)-(v) hereof
shall be accompanied by an instruction to suspend the use of the prospectus
until the requisite changes have been made):

                (i) when any Registration Statement and any amendment thereto
             has been filed with the Commission and when such Registration
             Statement or any post-effective amendment thereto has become
             effective;

                (ii) of any request by the Commission for amendments or
             supplements to any Registration Statement or the prospectus
             included therein or for additional information;

                (iii) of the issuance by the Commission of any stop order
             suspending the effectiveness of any Registration Statement or the
             initiation of any proceedings for that purpose;

                                       7
<PAGE>

                (iv) of the receipt by the Company of any notification with
             respect to the suspension of the qualification of the Securities,
             the Exchange Securities or the Private Exchange Securities for sale
             in any jurisdiction or the initiation or threatening of any
             proceeding for such purpose; and

                (v) of the happening of any event that requires the making of
             any changes in any Registration Statement or the prospectus
             included therein in order that the statements therein are not
             misleading and do not omit to state a material fact required to be
             stated therein or necessary to make the statements therein not
             misleading.

          (c) The Company and the Guarantors will make every reasonable effort
to obtain the withdrawal at the earliest practicable time of any order
suspending the effectiveness of any Registration Statement.

          (d) The Company will furnish to each Holder of Transfer Restricted
Securities included within the coverage of any Shelf Registration Statement,
without charge, at least one conformed copy of such Shelf Registration Statement
and any post-effective amendment thereto, including financial statements and
schedules and, if any such Holder so requests in writing, all exhibits thereto
(including those, if any, incorporated by reference).

          (e) The Company will, during the Shelf Registration Period, promptly
deliver to each Holder of Transfer Restricted Securities included within the
coverage of any Shelf Registration Statement, without charge, as many copies of
the prospectus (including each preliminary prospectus) included in such Shelf
Registration Statement and any amendment or supplement thereto as such Holder
may reasonably request; and the Company consents to the use of such prospectus
or any amendment or supplement thereto by each of the selling Holders of
Transfer Restricted Securities in connection with the offer and sale of the
Transfer Restricted Securities covered by such prospectus or any amendment or
supplement thereto.

          (f) The Company will furnish to each Initial Purchaser and each
Exchanging Dealer, and to any other Holder who so requests, without charge, at
least one conformed copy of the Exchange Offer Registration Statement and any
post-effective amendment thereto, including financial statements and schedules
and, if any Initial Purchaser or Exchanging Dealer or any such Holder so
requests in writing, all exhibits thereto (including those, if any, incorporated
by reference).

          (g) The Company will, during the Exchange Offer Registration Period or
the Shelf Registration Period, as applicable, promptly deliver to each Initial
Purchaser, each Exchanging Dealer and such other persons that are required to
deliver a prospectus following the Exchange Offer, without charge, as many
copies of the final prospectus included in the Exchange Offer Registration
Statement or the Shelf Registration Statement and any amendment or supplement
thereto as such Initial Purchaser, Exchanging Dealer or other persons may
reasonably request; and the Company and the Guarantors consent to the use of
such prospectus or any amendment or supplement thereto by any such Initial
Purchaser, Exchanging Dealer or other persons, as applicable, as aforesaid.

                                       8
<PAGE>

          (h) Prior to the effective date of any Registration Statement, the
Company and the Guarantors will use their reasonable best efforts to register or
qualify, or cooperate with the Holders of Securities, Exchange Securities or
Private Exchange Securities included therein and their respective counsel in
connection with the registration or qualification of, such Securities, Exchange
Securities or Private Exchange Securities for offer and sale under the
securities or blue sky laws of such jurisdictions as any such Holder reasonably
requests in writing and do any and all other acts or things necessary or
advisable to enable the offer and sale in such jurisdictions of the Securities,
Exchange Securities or Private Exchange Securities covered by such Registration
Statement; provided that the Company and the Guarantors will not be required to
qualify generally to do business in any jurisdiction where it is not then so
qualified or to take any action which would subject it to general service of
process or to taxation in any such jurisdiction where it is not then so subject.

          (i) The Company and the Guarantors will cooperate with the Holders of
Securities, Exchange Securities or Private Exchange Securities to facilitate the
timely preparation and delivery of certificates representing Securities,
Exchange Securities or Private Exchange Securities to be sold pursuant to any
Registration Statement free of any restrictive legends and in such denominations
and registered in such names as the Holders thereof may request in writing prior
to sales of Securities, Exchange Securities or Private Exchange Securities
pursuant to such Registration Statement.

          (j) If any event contemplated by Section 4(b)(ii) through (v) occurs
during the period for which the Company and the Guarantors are required to
maintain an effective Registration Statement, the Company will promptly prepare
and file with the Commission a post-effective amendment to the Registration
Statement or a supplement to the related prospectus or file any other required
document so that, as thereafter delivered to purchasers of the Securities,
Exchange Securities or Private Exchange Securities from a Holder, the prospectus
will not include an untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading.

          (k) Not later than the effective date of the applicable Registration
Statement, the Company will provide a CUSIP number for the Securities, the
Exchange Securities and the Private Exchange Securities, as the case may be, and
provide the applicable trustee with printed certificates for the Securities, the
Exchange Securities or the Private Exchange Securities, as the case may be, in a
form eligible for deposit with The Depository Trust Company.

          (l) The Company and the Guarantors will comply with all applicable
rules and regulations of the Commission and will make generally available to its
security holders as soon as practicable after the effective date of the
applicable Registration Statement an earning statement satisfying the provisions
of Section 11(a) of the Securities Act; provided that in no event shall such
earning statement be delivered later than 45 days after the end of a 12-month
period (or 90 days, if such period is a fiscal year) beginning with the first
month of the

                                       9
<PAGE>

Company's first fiscal quarter commencing after the effective date of the
applicable Registration Statement, which statement shall cover such 12-month
period.

          (m) The Company and the Guarantors will cause the Indenture or the
Exchange Securities Indenture, as the case may be, to be qualified under the
Trust Indenture Act as required by applicable law in a timely manner.

          (n) The Company may require each Holder of Transfer Restricted
Securities to be registered pursuant to any Shelf Registration Statement to
furnish to the Company such information concerning the Holder and the
distribution of such Transfer Restricted Securities as the Company may from time
to time reasonably require for inclusion in such Shelf Registration Statement,
and the Company may exclude from such registration the Transfer Restricted
Securities of any Holder that fails to furnish such information within a
reasonable time after receiving such request.

          (o) In the case of a Shelf Registration Statement, each Holder of
Transfer Restricted Securities to be registered pursuant thereto agrees by
acquisition of such Transfer Restricted Securities that, upon receipt of any
notice from the Company pursuant to Section 4(b)(ii) through (v), such Holder
will discontinue disposition of such Transfer Restricted Securities until such
Holder's receipt of copies of the supplemental or amended prospectus
contemplated by Section 4(j) or until advised in writing (the "Advice") by the
Company that the use of the applicable prospectus may be resumed. If the Company
shall give any notice under Section 4(b)(ii) through (v) during the period that
the Company is required to maintain an effective Registration Statement (the
"Effectiveness Period"), such Effectiveness Period shall be extended by the
number of days during such period from and including the date of the giving of
such notice to and including the date when each seller of Transfer Restricted
Securities covered by such Registration Statement shall have received (x) the
copies of the supplemental or amended prospectus contemplated by Section 4(j)
(if an amended or supplemental prospectus is required) or (y) the Advice (if no
amended or supplemental prospectus is required).

          (p) In the case of a Shelf Registration Statement, the Company and the
Guarantors shall enter into such customary agreements (including, if requested,
an underwriting agreement in customary form) and take all such other action, if
any, as Holders of a majority in aggregate principal amount of the Securities,
Exchange Securities and Private Exchange Securities being sold or the managing
underwriters (if any) shall reasonably request in order to facilitate any
disposition of Securities, Exchange Securities or Private Exchange Securities
pursuant to such Shelf Registration Statement.

          (q) In the case of a Shelf Registration Statement, the Company shall
(i) make reasonably available for inspection by a representative of, and Special
Counsel (as defined below) acting for, Holders of a majority in aggregate
principal amount of the Securities, Exchange Securities and Private Exchange
Securities being sold and any underwriter participating in any disposition of
Securities, Exchange Securities or Private Exchange Securities pursuant to such
Shelf Registration Statement, all relevant financial and other records,
pertinent

                                       10
<PAGE>

corporate documents and properties of the Company and its subsidiaries and (ii)
use its reasonable best efforts to have its officers, directors, employees,
accountants and counsel supply all relevant information reasonably requested by
such representative, Special Counsel or any such underwriter (an "Inspector") in
connection with such Shelf Registration Statement.

          (r) In the case of a Shelf Registration Statement, the Company shall,
if requested by Holders of a majority in aggregate principal amount of the
Securities, Exchange Securities and Private Exchange Securities being sold,
their Special Counsel or the managing underwriters (if any) in connection with
such Shelf Registration Statement, use its reasonable best efforts to cause (i)
its counsel to deliver an opinion relating to the Shelf Registration Statement
and the Securities, Exchange Securities or Private Exchange Securities, as
applicable, in customary form, (ii) its officers to execute and deliver all
customary documents and certificates requested by Holders of a majority in
aggregate principal amount of the Securities, Exchange Securities and Private
Exchange Securities being sold, their Special Counsel or the managing
underwriters (if any) and (iii) its independent public accountants to provide a
comfort letter or letters in customary form, subject to receipt of appropriate
documentation as contemplated, and only if permitted, by Statement of Auditing
Standards No. 72.

          5.  Registration Expenses.  The Company and the Guarantors will bear
all expenses incurred in connection with the performance of its obligations
under Sections 1, 2, 3 and 4 and the Company will reimburse the Initial
Purchasers and the Holders for the reasonable fees and disbursements of one firm
of attorneys (in addition to any local counsel) chosen by the Holders of a
majority in aggregate principal amount of the Securities, the Exchange
Securities and the Private Exchange Securities to be sold pursuant to each
Registration Statement (the "Special Counsel") acting for the Initial Purchasers
or Holders in connection therewith.

          6.  Indemnification.  (a) In the event of a Shelf Registration
Statement or in connection with any prospectus delivery pursuant to an Exchange
Offer Registration Statement by an Initial Purchaser or Exchanging Dealer, as
applicable, the Company and each of the Guarantors shall jointly and severally
indemnify and hold harmless each Holder (including, without limitation, any such
Initial Purchaser or Exchanging Dealer), its affiliates, their respective
officers, directors, employees, representatives and agents, and each person, if
any, who controls such Holder within the meaning of the Securities Act or the
Exchange Act (collectively referred to for purposes of this Section 6 and
Section 7 as a Holder) from and against any loss, claim, damage or liability,
joint or several, or any action in respect thereof (including, without
limitation, any loss, claim, damage, liability or action relating to purchases
and sales of Securities, Exchange Securities or Private Exchange Securities), to
which that Holder may become subject, whether commenced or threatened, under the
Securities Act, the Exchange Act, any other federal or state statutory law or
regulation, at common law or otherwise, insofar as such loss, claim, damage,
liability or action arises out of, or is based upon, (i) any untrue statement or
alleged untrue statement of a material fact contained in any such Registration
Statement or any prospectus forming part thereof or in any amendment or
supplement thereto or (ii) the omission or alleged omission to state therein a
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under

                                       11
<PAGE>

which they were made, not misleading, and shall reimburse each Holder promptly
upon demand for any legal or other expenses reasonably incurred by that Holder
in connection with investigating or defending or preparing to defend against or
appearing as a third party witness in connection with any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that the Company and the Guarantors shall not be liable in any such case to the
extent that any such loss, claim, damage, liability or action arises out of, or
is based upon, an untrue statement or alleged untrue statement in or omission or
alleged omission from any of such documents in reliance upon and in conformity
with any Holders' Information; and provided, further, that with respect to any
such untrue statement in or omission from any related preliminary prospectus,
the indemnity agreement contained in this Section 6(a) shall not inure to the
benefit of any Holder from whom the person asserting any such loss, claim,
damage, liability or action received Securities, Exchange Securities or Private
Exchange Securities to the extent that such loss, claim, damage, liability or
action of or with respect to such Holder results from the fact that both (A) a
copy of the final prospectus and any amendment or supplement thereto was not
sent or given to such person at or prior to the written confirmation of the sale
of such Securities, Exchange Securities or Private Exchange Securities to such
person and (B) the untrue statement in or omission from the related preliminary
prospectus was corrected in the final prospectus or any amendment or supplement
thereto unless, in either case, such failure to deliver the final prospectus or
any amendment or supplement thereto was a result of non-compliance by the
Company with Section 4(d), 4(e), 4(f) or 4(g).

          (b) In the event of a Shelf Registration Statement, each Holder shall
indemnify and hold harmless the Company, each Guarantor and their respective
affiliates, their respective officers, directors, employees, representatives and
agents, and each person, if any, who controls the Company or any Guarantor
within the meaning of the Securities Act or the Exchange Act (collectively
referred to for purposes of this Section 6(b) and Section 7 as the Company),
from and against any loss, claim, damage or liability, joint or several, or any
action in respect thereof, to which the Company may become subject, whether
commenced or threatened, under the Securities Act, the Exchange Act, any other
federal or state statutory law or regulation, at common law or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained in any such Registration Statement or any prospectus forming part
thereof or in any amendment or supplement thereto or (ii) the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, but in each case only
to the extent that the untrue statement or alleged untrue statement or omission
or alleged omission was made in reliance upon and in conformity with any
Holders' Information furnished to the Company by such Holder, and shall
reimburse the Company for any legal or other expenses reasonably incurred by the
Company in connection with investigating or defending or preparing to defend
against or appearing as a third party witness in connection with any such loss,
claim, damage, liability or action as such expenses are incurred; provided,
however, that no such Holder shall be liable for any indemnity claims hereunder
in excess of the amount of net proceeds received by such Holder from the sale of
Securities, Exchange Securities or Private Exchange Securities pursuant to such
Shelf Registration Statement.

                                       12
<PAGE>

          (c) Promptly after receipt by an indemnified party under this Section
6 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party pursuant to Section 6(a) or 6(b), notify the indemnifying
party in writing of the claim or the commencement of that action; provided,
however, that the failure to notify the indemnifying party shall not relieve it
from any liability which it may have under this Section 6 except to the extent
that it has been materially prejudiced by such failure; and provided, further,
that the failure to notify the indemnifying party shall not relieve it from any
liability which it may have to an indemnified party otherwise than under this
Section 6. If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Section 6 for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than the reasonable costs of investigation;
provided, however, that an indemnified party shall have the right to employ its
own counsel in any such action, but the fees, expenses and other charges of such
counsel for the indemnified party will be at the expense of such indemnified
party unless (1) the employment of counsel by the indemnified party has been
authorized in writing by the indemnifying party, (2) the indemnified party has
reasonably concluded (based upon written advice of counsel to the indemnified
party) that there may be legal defenses available to it or other indemnified
parties that are different from or in addition to those available to the
indemnifying party, (3) a conflict or potential conflict exists (based upon
written advice of counsel to the indemnified party) between the indemnified
party and the indemnifying party (in which case the indemnifying party will not
have the right to direct the defense of such action on behalf of the indemnified
party) or (4) the indemnifying party has not in fact employed counsel reasonably
satisfactory to the indemnified party to assume the defense of such action
within a reasonable time after receiving notice of the commencement of the
action, in each of which cases the reasonable fees, disbursements and other
charges of counsel will be at the expense of the indemnifying party or parties.
It is understood that the indemnifying party or parties shall not, in connection
with any proceeding or related proceedings in the same jurisdiction, be liable
for the reasonable fees, disbursements and other charges of more than one
separate firm of attorneys (in addition to any local counsel) at any one time
for all such indemnified party or parties. Each indemnified party, as a
condition of the indemnity agreements contained in Sections 6(a) and 6(b), shall
use all reasonable efforts to cooperate with the indemnifying party in the
defense of any such action or claim. No indemnifying party shall be liable for
any settlement of any such action effected without its written consent (which
consent shall not be unreasonably withheld), but if settled with its written
consent or if there be a final judgment for the plaintiff in any such action,
the indemnifying party agrees to indemnify and hold harmless any indemnified
party from and against any loss or liability by reason of such settlement or
judgment. No indemnifying party shall, without the prior written consent of the
indemnified party (which consent shall not be unreasonably withheld), effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been

                                       13
<PAGE>

sought hereunder by such indemnified party, unless such settlement (i) includes
an unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding and (ii) does not include a
statement or admission of fault, culpability or a failure to act, by or on
behalf of the indemnified party.

          7.  Contribution.  If the indemnification provided for in Section 6 is
unavailable or insufficient to hold harmless an indemnified party under Section
6(a) or 6(b), then each indemnifying party shall, in lieu of indemnifying such
indemnified party, contribute to the amount paid or payable by such indemnified
party as a result of such loss, claim, damage or liability, or action in respect
thereof, (i) in such proportion as shall be appropriate to reflect the relative
benefits received by the Company and the Guarantors from the offering and sale
of the Securities, on the one hand, and a Holder with respect to the sale by
such Holder of Securities, Exchange Securities or Private Exchange Securities,
on the other, or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company and each of the Guarantors on the one hand and such Holder
on the other with respect to the statements or omissions that resulted in such
loss, claim, damage or liability, or action in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the
Company and each of the Guarantors on the one hand and a Holder on the other
with respect to such offering and such sale shall be deemed to be in the same
proportion as the total net proceeds from the offering of the Securities (before
deducting expenses) received by or on behalf of the Company and each of the
Guarantors, on the one hand, and the total discounts and commissions received by
such Holder with respect to the Securities, Exchange Securities or Private
Exchange Securities, on the other, bear to the total gross proceeds from the
sale of Securities, Exchange Securities or Private Exchange Securities. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to the Company and each of the
Guarantors or information supplied by the Company and each of the Guarantors on
the one hand or to any Holders' Information supplied by such Holder on the
other, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such untrue statement or
omission. The parties hereto agree that it would not be just and equitable if
contributions pursuant to this Section 7 were to be determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to herein. The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability, or
action in respect thereof, referred to above in this Section 7 shall be deemed
to include, for purposes of this Section 7, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending or preparing to defend any such action or claim. Notwithstanding
the provisions of this Section 7, an indemnifying party that is a Holder of
Securities, Exchange Securities or Private Exchange Securities shall not be
required to contribute any amount in excess of the amount by which the total
price at which the Securities, Exchange Securities or Private Exchange
Securities sold by such indemnifying party to any purchaser exceeds the amount
of any damages which such indemnifying party has otherwise paid or become liable
to pay by reason of any untrue or alleged untrue statement or omission or
alleged omission.

                                       14
<PAGE>

No person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          8.  Rules 144 and 144A.  The Company shall use its reasonable best
efforts to file the reports required to be filed by it under the Securities Act
and the Exchange Act in a timely manner and, if at any time the Company is not
required to file such reports, it will, upon the written request of any Holder
of Transfer Restricted Securities, make publicly available other information so
long as necessary to permit sales of such Holder's securities pursuant to Rules
144 and 144A. The Company and the Guarantors covenant that they will take such
further action as any Holder of Transfer Restricted Securities may reasonably
request, all to the extent required from time to time to enable such Holder to
sell Transfer Restricted Securities without registration under the Securities
Act within the limitation of the exemptions provided by Rules 144 and 144A
(including, without limitation, the requirements of Rule 144A(d)(4)). Upon the
written request of any Holder of Transfer Restricted Securities, the Company and
the Guarantors shall deliver to such Holder a written statement as to whether it
has complied with such requirements. Notwithstanding the foregoing, nothing in
this Section 8 shall be deemed to require the Company to register any of its
securities pursuant to the Exchange Act.

          9.  Underwritten Registrations.  If any of the Transfer Restricted
Securities covered by any Shelf Registration Statement are to be sold in an
underwritten offering, the investment banker or investment bankers and manager
or managers that will administer the offering will be selected by the Holders of
a majority in aggregate principal amount of such Transfer Restricted Securities
included in such offering, subject to the consent of the Company (which shall
not be unreasonably withheld or delayed), and such Holders shall be responsible
for all underwriting commissions and discounts in connection therewith.

          No person may participate in any underwritten registration hereunder
unless such person (i) agrees to sell such person's Transfer Restricted
Securities on the basis reasonably provided in any underwriting arrangements
approved by the persons entitled hereunder to approve such arrangements and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

          10. Exchange of Existing 10 7/8% Senior Subordinated Notes.
Notwithstanding any other provision of this Agreement, the Company may register
the exchange of the 10 7/8% Senior Subordinated Notes due 2007 that the Company
issued under the Indenture (as amended to the date hereof) dated as of April 9,
1997 (the "1997 Notes"), in the Exchange Offer Registration Statement filed
hereunder; provided that the securities issued in exchange for such securities
and the Exchange Securities must be issued under the same indenture (whether the
Indenture or the Exchange Securities Indenture). If the 1997 Notes are covered
by the Exchange Offer Registration Statement pursuant to this Section 10, the
terms "Exchange Offer" shall include the offer to exchange the 1997 Notes.

                                       15
<PAGE>

          11.  Miscellaneous.  (a) Amendments and Waivers. The provisions of
this Agreement may not be amended, modified or supplemented, and waivers or
consents to departures from the provisions hereof may not be given, unless the
Company has obtained the written consent of Holders of a majority in aggregate
principal amount of the Securities, the Exchange Securities and the Private
Exchange Securities, taken as a single class. Notwithstanding the foregoing, a
waiver or consent to depart from the provisions hereof with respect to a matter
that relates exclusively to the rights of Holders whose Securities, Exchange
Securities or Private Exchange Securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect the
rights of other Holders may be given by Holders of a majority in aggregate
principal amount of the Securities, the Exchange Securities and the Private
Exchange Securities being sold by such Holders pursuant to such Registration
Statement.

          (b) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail,
telecopier or air courier guaranteeing next-day delivery:

                (1) if to a Holder, at the most current address given by such
             Holder to the Company in accordance with the provisions of this
             Section 10(b), which address initially is, with respect to each
             Holder, the address of such Holder maintained by the Registrar
             under the Indenture, with a copy in like manner to J. P. Morgan
             Securities Inc. and Merrill Lynch, Pierce, Fenner & Smith
             Incorporated;

                (2) if to an Initial Purchaser, initially at its address set
             forth in the Purchase Agreement;

                (3) if to the Company, initially at the address of the Company
             set forth in the Purchase Agreement; and

                (4) if to the Guarantors, initially at the address of the
             Guarantors set forth in the Purchase Agreement.

          All such notices and communications shall be deemed to have been duly
given: when delivered by hand, if personally delivered; one business day after
being delivered to a next-day air courier; five business days after being
deposited in the mail; and when receipt is acknowledged by the recipient's
telecopier machine, if sent by telecopier.

          (c) Successors And Assigns. This Agreement shall be binding upon the
Company, the Guarantors and their respective successors and assigns.

          (d) Counterparts. This Agreement may be executed in any number of
counterparts (which may be delivered in original form or by telecopier) and by
the parties hereto in separate counterparts, each of which when so executed
shall be deemed to be an original and all of which taken together shall
constitute one and the same agreement.

                                       16
<PAGE>

          (e) Definition of Terms. For purposes of this Agreement, (a) the term
"business day" means any day on which the New York Stock Exchange, Inc. is open
for trading, (b) the term "subsidiary" has the meaning set forth in Rule 405
under the Securities Act and (c) except where otherwise expressly provided, the
term "affiliate" has the meaning set forth in Rule 405 under the Securities Act.

          (f) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

          (g) Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York.

          (h) Remedies. In the event of a breach by the Company or any of the
Guarantors or by any Holder of any of their respective obligations under this
Agreement, each Holder or the Company or any Guarantor, as the case may be, in
addition to being entitled to exercise all rights granted by law, including
recovery of damages (other than the recovery of damages for a breach by the
Company or any Guarantor of their obligations under Sections 1 or 2 hereof for
which additional interest has been paid pursuant to Section 3 hereof), will be
entitled to specific performance of its rights under this Agreement. The
Company, each Guarantor and each Holder agree that monetary damages would not be
adequate compensation for any loss incurred by reason of a breach by it of any
of the provisions of this Agreement and hereby further agree that, in the event
of any action for specific performance in respect of such breach, it shall waive
the defense that a remedy at law would be adequate.

          (i) No Inconsistent Agreements. Each of the Company and each Guarantor
represents, warrants and agrees that (i) it has not entered into, shall not, on
or after the date of this Agreement, enter into any agreement that is
inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof, (ii) it has not previously
entered into any agreement which remains in effect granting any registration
rights with respect to any of its debt securities to any person and (iii)
without limiting the generality of the foregoing, without the written consent of
the Holders of a majority in aggregate principal amount of the then outstanding
Transfer Restricted Securities, it shall not grant to any person the right to
request the Company to register any debt securities of the Company under the
Securities Act unless the rights so granted are not in conflict or inconsistent
with the provisions of this Agreement.

          (j) No Piggyback on Registrations. Neither the Company nor the
Guarantors nor any of its security holders (other than the Holders of Transfer
Restricted Securities in such capacity) shall have the right to include any
securities of the Company in any Shelf Registration or Exchange Offer other than
Transfer Restricted Securities.

          (k) Severability. The remedies provided herein are cumulative and not
exclusive of any remedies provided by law. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein

                                       17
<PAGE>

shall remain in full force and effect and shall in no way be affected, impaired
or invalidated, and the parties hereto shall use their reasonable best efforts
to find and employ an alternative means to achieve the same or substantially the
same result as that contemplated by such term, provision, covenant or
restriction. It is hereby stipulated and declared to be the intention of the
parties that they would have executed the remaining terms, provisions, covenants
and restrictions without including any of such that may be hereafter declared
invalid, illegal, void or unenforceable.

                                       18

          Each broker-dealer that receives Exchange Securities for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities.  The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.  This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Securities received in exchange for
Securities where such Securities were acquired by such broker-dealer as a result
of market-making activities or other trading activities.  The Company has agreed
that, for a period of 180 days after the Expiration Date (as defined herein), it
will make this Prospectus available to any broker-dealer for use in connection
with any such resale.  See "Plan of Distribution."

          Each broker-dealer that receives Exchange Securities for its own
account in exchange for Securities, where such Securities were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Securities.  See "Plan of Distribution".

                              PLAN OF DISTRIBUTION

          Each broker-dealer that receives Exchange Securities for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities.  This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Securities received in
exchange for Securities where such Securities were acquired as a result of
market-making activities or other trading activities.  The Company has agreed
that, for a period of 180 days after the Expiration Date, it will make this
prospectus, as amended or supplemented, available to any broker-dealer for use
in connection with any such resale.  In addition, until _______________, 200_,
all dealers effecting transactions in the Exchange Securities may be required to
deliver a prospectus.

          The Company will not receive any proceeds from any sale of Exchange
Securities by broker-dealers.  Exchange Securities received by broker-dealers
for their own account pursuant to the Exchange Offer may be sold from time to
time in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Securities or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or at negotiated
prices.  Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer or the purchasers of any such Exchange
Securities.  Any broker-dealer that resells Exchange Securities that were
received by it for its own account pursuant to the Exchange Offer and any broker
or dealer that participates in a distribution of such Exchange Securities may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit on any such resale of Exchange Securities and any commission or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act.  The Letter of Transmittal states that,
by acknowledging that it will deliver and by delivering a prospectus, a broker-
dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

          For a period of 180 days after the Expiration Date the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal.  The Company has agreed to pay all expenses
incident to the Exchange Offer (including the expenses of one counsel for the
Holders of the Securities) other than commissions or concessions of any broker-
dealers and will indemnify the Holders of the Securities (including any broker-
dealers) against certain liabilities, including liabilities under the Securities
Act.

     .  CHECK HERE IF YOU ARE A BROKER-DEALER AND WISH TO RECEIVE 10 ADDITIONAL

tenor signed by such Holders in person or by an agent duly appointed in writing.
If Securities of a series are issuable as Bearer Securities, any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders of such series may,
alternatively, be embodied in and evidenced by the record of Holders of
Securities of such series voting in favor thereof, either in person or by
proxies duly appointed in writing, at any meeting of Holders of Securities of
such series duly called and held in accordance with the provisions of Article
Fourteen, or a combination of such instruments and any such record. Except as
herein otherwise expressly provided, such action shall become effective when
such instrument or instruments or record or both are delivered to the Trustee
and, where it is hereby expressly required, to the Company. Such instrument or
instruments and any such record (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments and so voting at any such meeting. Proof of
execution of any such instrument or of a writing appointing any such agent or
proxy or of the holding by any Person of a Security, shall be sufficient for any
purpose of this Indenture and (subject to Section 601) conclusive in favor of
the Trustee and the Company, if made in the manner provided in this Section. The
record of any meeting of Holders of Securities shall be proved in the manner
provided in Section 1406.

     (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

     (c)  The Company may, in the circumstances permitted by the Trust Indenture
Act, fix any day as the record date for the purpose of determining the Holders
of Registered Securities of any series entitled to give or take any request,
demand, authorization, direction, notice, consent, waiver or other action, or to
vote on any action, authorized or permitted to be given or taken by Holders of
Securities of such series. If not set by the Company prior to the first
solicitation of a Holder of Securities of such series made by any Person in
respect of any such action, or, in the case of any such vote, prior to such
vote, the record date for any such action or vote shall be the 30th day (or, if
later,

                                      -9-
<PAGE>

Section 701) prior to such first solicitation or vote, as the case may be. With
regard to any record date for action to be taken by the Holders of one or more
series of Securities, only the Holders of Securities of such series on such date
(or their duly designated proxies) shall be entitled to give or take, or vote
on, the relevant action.

     (d)  The principal amount and serial numbers of Registered Securities held
by any Person, and the date of holding the same, shall be proved by the Security
Register.

     (e)  The principal amount and serial numbers of Bearer Securities held by
any Person, and the date of holding the same, may be proved by the production of
such Bearer Securities or by a certificate executed, as depositary, by any trust
company, bank, banker or other depositary, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such Person had on deposit with such depositary, or
exhibited to it, the Bearer Securities therein described; or such facts may be
proved by the certificate or affidavit of the Person holding such Bearer
Securities, if such certificate or affidavit is deemed by the Trustee to be
satisfactory. The Trustee and the Company may assume that such ownership of any
Bearer Security continues until (1) another certificate or affidavit bearing a
later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The principal amount and
serial numbers of Bearer Securities held by any Person, and the date of holding
the same, may also be proved in any other manner which the Trustee deems
sufficient.

     (f)  Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security. Any Holder or subsequent Holder may revoke the request, demand,
authorization, direction, notice, consent, waiver or other Act as to his
Security or portion of his Security; provided, however, that such revocation
shall be effective only if the Trustee receives notice of such revocation before
the date the Act becomes effective.

     (g)  Without limiting the foregoing, a Holder entitled hereunder to give or
take any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any different part of such principal amount.

Securities is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder of a Registered
Security shall affect the sufficiency of such notice with respect to other
Holders of Registered Securities or the sufficiency of any notice to Holders of
Bearer Securities given as provided herein.

     In case by the reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such

                                      -11-

Holders for every purpose hereunder. Neither the failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice to Holders
of Registered Securities given as provided herein.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders of Securities shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

SECTION 1.07   Language of Notices, etc.

     Any request, demand, authorization, direction, notice, consent or waiver
required or permitted under this Indenture shall be in the English language,
except that any published notice may be in an official language of the country
of publication.

SECTION 1.08   Conflict With Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with a provision of
the Trust Indenture Act that is required under the Trust Indenture Act to be a
part of and govern this Indenture or any other provision of this Indenture that
is required to be in this Indenture by the Trust Indenture Act, such required
provision shall control. If any provision of this Indenture modifies or excludes
any provision of the Trust Indenture Act that may be so modified or excluded,
the latter provision shall be deemed to apply to this Indenture as so modified
or to be excluded, as the case may be.

SECTION 1.09   Effect of Headings and Table of Contents.

     The Article and Section headings herein and the Table of Contents are for

its successors and assigns, whether so expressed or not.

SECTION 1.11   Separability Clause.

     In case any provision in this Indenture or the Securities or coupons shall
be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired
thereby.

SECTION 1.12   Benefits of Indenture.

     Nothing in this Indenture or the Securities or coupons, express or implied,
shall give to any Person, other than the parties hereto, their successors
hereunder and the Holders of Securities and coupons, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

     This Indenture and the Securities and coupons shall be governed by and
construed in accordance with the laws of the State of New York, without regard
to principles of conflicts of laws.

SECTION 1.14   Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
or coupons other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu of this Section)
payment of interest or principal (and premium, if any) need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date or Redemption Date, or at the Stated Maturity, PROVIDED
that no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date, Redemption Date or Stated Maturity, as the
case may be.

Securities, if any, of each series and related coupons shall be in substantially
the form (including temporary or permanent global form) as shall be established
by or pursuant to a Board Resolution of the Company or in one or more indentures
supplemental hereto, in each case with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture, and may have such letters, numbers or other marks of identification
and such legends or endorsements placed thereon as may be required to comply
with law, or with the rules of any securities exchange or to conform to general
usage, all as may, consistently herewith, be determined by the officers
executing such Securities or coupons, as evidenced by their execution of the
Securities or coupons. If temporary Securities of any series are issued in
global form as permitted by Section 304, the form thereof shall be established
as provided in the preceding sentence. A copy of the Board Resolution of the
Company establishing the forms of Securities or coupons of any series (or any
such temporary global Security) shall be certified by the Secretary or an
Assistant Secretary of the Company and delivered to the Trustee at or prior to
the delivery of the Company Order contemplated by Section 303 for the

Security) or coupons.

     Unless otherwise specified as contemplated by Section 301, Securities in
bearer form shall have interest coupons attached.

     The definitive Securities and coupons, if any, shall be printed,
lithographed or engraved on steel engraved borders or may be produced in any
other manner, all as determined by the officers executing such Securities as
evidenced by their execution of such Securities or coupons.

SECTION 2.02   Form of Trustee's Certificate of Authentication.

     The Trustee's certificate of authentication shall be in substantially the
following form:

SECTION 2.03   Securities in Global Form.

     If Securities of a series are issuable in global form, as contemplated by
Section 301, then, notwithstanding clause (10) of Section 301 and the provisions
of Section 302, any such Security shall represent such of the Outstanding
Securities of such series as shall be specified therein and may provide that it
shall represent the aggregate amount of Outstanding Securities from time to time
endorsed thereon and that the aggregate amount of Outstanding Securities
represented thereby may be reduced to reflect exchanges. Any endorsement of a
Security in global form to reflect the amount, or any increase or decrease in
the amount, of Outstanding Securities represented thereby shall be made by the
Trustee in such manner and upon instructions given by such Person or Persons as
shall be specified therein or in the Company Order to be delivered to the
Trustee pursuant to Section 303 or Section 304. Subject to the provisions of
Section 303 and, if applicable, Section 304, the Trustee shall deliver and
redeliver any Security in permanent global form in the manner and upon
instructions given by the Person or Persons specified therein or in the
applicable Company Order. If a Company Order pursuant to Section 303 or 304 has
been, or simultaneously is, delivered, any instructions by the Company with
respect to endorsement or delivery or redelivery of a Security in global form
shall be in writing but need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel.

     The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

     Notwithstanding the provisions of Sections 201 and 307, unless otherwise
specified as contemplated by Section 301, payment of principal of and any
premium and interest on any Security in permanent global form shall be made to
the Person or Persons specified therein.

hereinafter referred to and is registered in the name of a Depository or a
nominee of a Depository. This Security is exchangeable for Securities registered
in the name of a Person other than the Depository or its nominee only in the
limited circumstances described in the Indenture, and no transfer of this

circumstances."

delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

SECTION 3.02   Denominations.

     Unless otherwise provided as contemplated by Section 301 with respect to

SECTION 3.03   Execution, Authentication, Delivery and Dating.

                                      -17-
<PAGE>

     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its President, its Treasurer or its Chief Financial Officer, under
its corporate seal reproduced thereon attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Securities
may be manual or facsimile. Coupons shall bear the facsimile signature of the
Treasurer or any Assistant Treasurer of the Company.

     Securities and coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities or coupons.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series, together with any
coupons appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; PROVIDED, HOWEVER, that,
unless otherwise provided with respect to such series, in connection with its
original issuance, during the "restricted period" (as defined in Section 1.163-
5(c)(2)(i)(D)(7) of the United States Treasury Regulations) (the "restricted
period") no Bearer Security shall be mailed or otherwise delivered to any
location in the United States; and PROVIDED, FURTHER, that, unless otherwise
provided with respect to such series, a Bearer Security may be delivered in
connection with its original issuance only if the Person entitled to receive
such Bearer Security shall have furnished a certificate in the form set forth in
Exhibit A to this Indenture, dated no earlier than the Certification Date. If
any Security shall be represented by a permanent global Bearer Security, then,
for purposes of this Section and Section 304, the notation of a beneficial
owner's interest therein upon original issuance of such Security or upon
exchange of a portion of a temporary global Security shall be deemed to be
delivery in connection with its original issuance during the restricted period
of such beneficial owner's interest in such permanent global Security. Except as
permitted by Section 306, the Trustee shall not authenticate and deliver any
Bearer Security unless all appurtenant coupons for interest then matured have
been detached and cancelled.

     In authenticating Securities, the Trustee shall be entitled to receive, and
(subject to Section 601) shall be fully protected in relying upon, an Opinion of
Counsel stating:

     (a)  that the forms of such Securities and coupons established by or
pursuant to a Board Resolution of the Company as contemplated by Section 201
have been established in conformity with the provisions of this Indenture;

     (b)  if the terms of such Securities and any coupons have been established
by or pursuant to a Board Resolution of the Company as permitted by Section 301,
that such terms have been established in conformity with the provisions of this
Indenture; and

     (c)  that such Securities, together with any coupons appertaining thereto,
when authenticated and delivered by the Trustee and issued by the Company in the
manner and subject to any conditions specified in such Opinion of Counsel, will
constitute valid and legally binding obligations of the Company enforceable in
accordance with their terms, subject to bankruptcy,

                                      -18-
<PAGE>

insolvency, fraudulent transfer, reorganization and other laws of general
applicability relating to or affecting creditors' rights and to general equity
principles.

     Such Opinion of Counsel shall also cover such other matters as the Trustee
may reasonably request.

     The Trustee shall not be required to authenticate such Securities the forms
or terms of which have been established by or pursuant to a Board Resolution of
the Company if the issue of such Securities pursuant to this Indenture will
affect the Trustee's own rights, duties or immunities under the Securities and
this Indenture or otherwise in a manner which is not reasonably acceptable to
the Trustee.

     Notwithstanding the provisions of Section 301 and of the two preceding
paragraphs, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraphs at or prior to the time
of authentication of each Security of such series if such documents are
delivered at or prior to the authentication upon issuance of the first Security
of such series to be issued.

     After the original issuance of the first Security of such series to be
issued, any separate request by the Company that the Trustee authenticate
Securities of such series for original issuance will be deemed to be a
certification by the Company (which, subject to Section 601, the Trustee shall
be fully protected in relying on) that it is in compliance with all conditions
precedent provided for in this Indenture relating to the authentication and
delivery of such Securities.

     Each Registered Security shall be dated the date of its authentication; and
each Bearer Security shall be dated as of the date of original issuance of the
first Security of such series to be issued.

     No Security or coupon shall be entitled to any benefit under this Indenture
or be valid or obligatory for any purpose unless there appears on such Security,
or the Security to which such coupon appertains, a certificate of authentication
substantially in the form provided for herein executed by the Trustee by manual
signature, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder. Notwithstanding the foregoing, if any Security shall have
been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 309 together with a written statement (which
need not comply with Section 102 and need not be accompanied by an Opinion of
Counsel) stating that such Security has never been issued and sold by the
Company, for all purposes of this Indenture such Security shall be deemed never
to have been authenticated and delivered hereunder and shall never be entitled
to the benefits of this Indenture.

SECTION 3.04   Temporary Securities.

     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten or otherwise
produced, in any authorized denomination, substantially of the tenor of the
definitive Securities in lieu of which they are issued, in registered form or,
if authorized, in bearer form with one or more coupons or without coupons, and
with such appropriate insertions, omissions, substitutions and other variations
as the officers executing such Securities may determine, as evidenced by their
execution of such Securities. In the case of any series issuable as Bearer
Securities, such temporary Securities may be in global form. A temporary Bearer
Security shall be delivered only in compliance with the conditions set forth in
Section 303.

     Except in the case of temporary Securities in global form (which shall be
exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without unreasonable delay. After the
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company maintained pursuant to Section 1002 in a Place of Payment for such
series for the purpose of exchanges of Securities of such series without charge
to the Holder. Upon surrender for cancellation of any one or more temporary
Securities of any series (accompanied by any unmatured coupons appertaining
thereto) the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like aggregate principal amount of definitive
Securities of the same series and of like tenor of authorized denominations;
PROVIDED, HOWEVER, that no definitive Bearer Security shall be issued in
exchange for a temporary Registered Security.

     If temporary Securities of any series are issued in global form, any such
temporary global Security shall, unless otherwise provided therein, be delivered
to the London office of a depositary or common depositary (the "Common
Depositary"), for the benefit of Euro-clear and CEDEL S.A., for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

     Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security of a series (the "Exchange Date"), the Company shall deliver to the
Trustee definitive Securities of that series in aggregate principal amount equal
to the principal amount of such temporary global Security, executed by the
Company. On or after the Exchange Date such temporary global Security shall be
surrendered by the Common Depositary to the Trustee, as the Company's agent for
such purpose, to be exchanged, in whole or from time to time in part, for
definitive Securities of that series without charge and the Trustee shall
authenticate and deliver, in exchange for each portion of such temporary global
Security, a like aggregate principal amount of definitive Securities of the same
series of authorized denominations and of like tenor as the portion of such
temporary global Security to be exchanged; provided, however, that, unless
otherwise specified in such temporary global Security, upon such presentation by
the Common Depositary, such temporary global Security is accompanied by a
certificate dated the Exchange Date or a subsequent date and signed by Euro-
clear as to the portion of such temporary global Security held for its account
then to be exchanged and a certificate dated the Exchange Date

                                      -20-
<PAGE>

or a subsequent date and signed by CEDEL S.A. as to the portion of such
temporary global Security held for its account then to be exchanged, each in the
form set forth in Exhibit B to this Indenture. The definitive Securities to be
delivered in exchange for any such temporary global Security shall be in bearer
form, registered form, permanent global bearer form or permanent global
registered form, or any combination thereof, as specified as contemplated by
Section 301, and if any combination thereof is so specified, as requested by the
beneficial owner thereof; PROVIDED, HOWEVER, that no definitive Bearer Security
or permanent global Security shall be delivered in exchange for a temporary
Bearer Security except in compliance with the conditions set forth in Section
303.

     Unless otherwise specified in the temporary global Security, the interest
of a beneficial owner of Securities of a series in a temporary global Security
shall be exchanged on the Exchange Date for definitive Securities (and where the
form of the definitive Securities is not specified by the Holder for an interest
in a permanent global Security) of the same series and of like tenor unless, on
or prior to the Exchange Date, such beneficial owner has not delivered to Euro-
clear or CEDEL S.A., as the case may be, a certificate in the form set forth in
Exhibit A to this Indenture dated no earlier than the Certification Date, copies
of which certificate shall be available from the offices of Euro-clear and CEDEL
S.A., the Trustee, any Authenticating Agent appointed for such series of
Securities and each Paying Agent and after the Exchange Date, the interest of a
beneficial owner of Securities of a series in a temporary global Security shall
be exchanged for definitive Securities (and where the form of the definitive
Securities is not specified by the Holder for an interest in a permanent global
Security) of the same series and of like tenor following such beneficial owner's
delivery to Euro-clear or CEDEL S.A., as the case may be, of a certificate in
the form set forth in Exhibit A to this Indenture dated no earlier than the
Certification Date. Unless otherwise specified in such temporary global
Security, any exchange shall be made free of charge to the beneficial owners of
such temporary global Security, except that a Person receiving definitive
Securities must bear the cost of insurance, postage, transportation and the like
in the event that such Person does not take delivery of such definitive
Securities in person at the offices of Euro-clear or CEDEL S.A. Definitive
Securities in bearer form to be delivered in exchange for any portion of a
temporary global Security shall be delivered only outside the United States.

     Until exchanged in full as hereinabove provided, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and of like tenor
authenticated and delivered hereunder, except that, unless otherwise specified
as contemplated by Section 301, interest payable on a temporary global Security
on an Interest Payment Date for Securities of such series shall be payable to
Euro-clear and CEDEL S.A. on such Interest Payment Date upon delivery by Euro-
clear and CEDEL S.A. to the Trustee of a certificate or certificates in the form
set forth in Exhibit B to this Indenture, for credit without further interest on
or after such Interest Payment Date to the respective accounts of the Persons
who are the beneficial owners of such temporary global Security on such Interest
Payment Date and who have each delivered to Euro-clear or CEDEL S.A., as the
case may be, a certificate in the form set forth in Exhibit A to this Indenture.
Any interest so received by Euro-clear and CEDEL S.A. and not paid as herein
provided shall be returned to the Trustee immediately prior to the expiration of
two years after such Interest Payment Date in order to be repaid to the Company
in accordance with Section 1003.

SECTION 3.05   Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept at an office or agency to be maintained
by the Company in accordance with Section 1002 a register (being the combined
register of the Security Registrar and all transfer agents designated pursuant
to Section 1002 for the purpose of registration of transfer of Securities and
sometimes collectively referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Company shall provide
for the registration of each series of Registered Securities and the
registration of transfers of such Registered Securities. The Company shall serve
initially as "Security Registrar" for the purpose of registering Registered
Securities and transfers of Registered Securities as herein provided.

     Upon surrender for registration of transfer of any Registered Security of
any series at the office or agency of the Company maintained pursuant to Section
1002 for such purpose in a Place of Payment for such series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities of
the same series of any authorized denominations and of a like aggregate
principal amount and tenor.

     At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, upon surrender
of the Securities to be exchanged at any such office or agency. Whenever any
Securities are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive. Unless otherwise provided with respect to
any series of Securities, Bearer Securities may not be issued in exchange for
Registered Securities.

     At the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, upon surrender
of the Bearer Securities to be exchanged at any such office or agency, with all
unmatured coupons and all matured coupons in default thereto appertaining. If
the Holder of a Bearer Security is unable to produce any such unmatured coupon
or coupons or matured coupon or coupons in default, such exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Security shall surrender to any Paying Agent any
such missing coupon in respect of which such a payment shall have been made,
such Holder shall be entitled to receive the amount of such payment; provided,
however, that, except as otherwise provided in Section 1002, interest
represented by coupons shall be payable only upon presentation and surrender of
those coupons at an office or agency located outside the United States.
Notwithstanding the foregoing, in case a Bearer Security of any series is
surrendered at any such office or agency in exchange for a Registered Security
of the same series and like tenor after the close of business at such office or
agency on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, such Bearer Security
shall be

                                      -22-
<PAGE>

surrendered without the coupon relating to such Interest Payment Date or
proposed date for payment, as the case may be, and interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security but will be payable only to
the Holder of such coupon when due in accordance with the provisions of this
Indenture. Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

     Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be exchangeable
only as provided in this paragraph. If the beneficial owners of interests in a
permanent global Security are entitled to exchange such interests for Securities
of such series and of like tenor and principal amount of another authorized form
and denomination, as specified as contemplated by Section 301, then without
unnecessary delay but in any event not later than the earliest date on which
such interests may be so exchanged, the Company shall deliver to the Trustee
definitive Securities of that series in an aggregate principal amount equal to
the principal amount of such permanent global Security, executed by the Company.
On or after the earliest date on which such interests may be so exchanged, such
permanent global Security shall be surrendered from time to time in accordance
with instructions given to the Trustee and the Common Depositary (which
instructions shall be in writing but need not comply with Section 102 or be
accompanied by an Opinion of Counsel) by the Common Depositary or such other
depositary or Common Depositary as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities of the same series
without charge and the Trustee shall authenticate and deliver, in exchange for
each portion of such permanent global Security, a like aggregate principal
amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such permanent global Security to be
exchanged which, unless the Securities of the series are not issuable both as
Bearer Securities and as Registered Securities, as specified as contemplated by
Section 301, shall be in the form of Bearer Securities or Registered Securities,
or any combination thereof, as shall be specified by the beneficial owner
thereof; PROVIDED, HOWEVER, that no such exchanges may occur during a period
beginning at the opening of business 15 days before any selection of Securities
of that series is to be redeemed and ending on the relevant Redemption Date; and
PROVIDED, FURTHER, that no Bearer Security delivered in exchange for a portion
of a permanent global Security shall be mailed or otherwise delivered to any
location in the United States. Promptly following any such exchange in part,
such permanent global Security shall be returned by the Trustee to the Common
Depositary or such other depositary or Common Depositary referred to above in
accordance with the instructions of the Company referred to above. If a
Registered Security is issued in exchange for any portion of a permanent global
Security after the close of business at the office or agency where such exchange
occurs on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of such Registered
Security, but will be payable on such Interest Payment Date or proposed date for
payment, as the case may be, only to the Person to whom interest in respect of
such portion of such permanent global Security is payable in accordance with
provisions of this Indenture.

                                      -23-

     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange. Every Registered
Security presented or surrendered for registration of transfer or exchange shall
(if so required by the Company or the Trustee or any transfer agent) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar or any transfer agent
duly executed, by the Holder thereof or his attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

     The Company shall not be required (i) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before any selection of Securities of that series to be
redeemed and ending at the close of business on (A) if Securities of the series
are issuable only as Registered Securities, the day of the mailing of the
relevant notice of redemption and (B) if Securities of the series are issuable
as Bearer Securities, the day of the first publication of the relevant notice of
redemption, or if Securities of the series are also issuable as Registered
Securities and there is no publication, the mailing of the relevant notice of
redemption, or (ii) to register the transfer of or exchange any Registered
Security so selected for redemption, in whole or in part, except the unredeemed
portion of any Registered Security being redeemed in part, or (iii) to exchange
any Bearer Security so selected for redemption except that such a Bearer
Security may be exchanged for a Registered Security of that series and like
tenor, PROVIDED that such Registered Security shall be simultaneously
surrendered for redemption.

     Notwithstanding the foregoing and except as otherwise specified or
contemplated by Section 301, any Book-Entry Security shall be exchangeable
pursuant to this Section 305 or Sections 304, 906 and 1107 for Securities
registered in the name of, and a transfer of a Book-Entry Security of any series
may be registered to, any Person other than the Depository for such Security or
its nominee only if (i) such Depository notifies the Company that it is
unwilling or unable to continue as Depository for such Book-Entry Security or if
at any time such Depository ceases to be a clearing agency registered under the
Securities Exchange Act of 1934, as amended, (ii) the Company executes and
delivers to the Trustee a Company Order that such Book-Entry Security shall be
so exchangeable and the transfer thereof so registrable or (iii) there shall
have occurred and be continuing an Event of Default, with respect to the
Securities of such series. Upon the occurrence in respect of any Book-Entry
Security of any series of any one or more of the conditions specified in clause
(i), (ii) or (iii) of the preceding sentence or such other conditions as may be
specified, such Book-Entry Security may be exchanged for Securities registered
in the names of, and the transfer of such Book-Entry Security may be registered
to, such Persons (including Persons other than the Depository with respect to
such series and its nominees) as such Depository shall direct. Notwithstanding
any other provision of this Indenture, any Security authenticated and delivered
upon registration of transfer of, or in exchange for, or in lieu of, any Book-
Entry Security shall also be a Book-Entry Security and shall bear the legend
specified in Section 204 except for any Security authenticated and delivered in
exchange for, or upon registration of transfer of, a Book-Entry Security
pursuant to the preceding sentence.

SECTION 3.06   Mutilated, Destroyed, Lost and Stolen Securities and Coupons.

     If any mutilated Security or a Security with a mutilated coupon
appertaining thereto is surrendered to the Trustee, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same series and of like tenor and principal amount and bearing a
number not contemporaneously outstanding, with coupons corresponding to the
coupons, if any, appertaining to the surrendered Security.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or coupon
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security or coupon has been acquired by a
bona fide purchaser, the Company shall execute and the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen Security
or in exchange for the Security to which a destroyed, lost or stolen coupon
appertains (with all appurtenant coupons not destroyed, lost or stolen), a new
Security of the same series and of like tenor and principal amount and bearing a
number not contemporaneously outstanding, with coupons corresponding to the
coupons, if any, appertaining to such destroyed, lost or stolen Security or to
the Security to which such destroyed, lost or stolen coupon appertains.

     In case any such mutilated, destroyed, lost or stolen Security or coupon
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security or coupon; PROVIDED,
HOWEVER, that the principal of and any premium and interest on Bearer Securities
shall, except as otherwise provided in Section 1002, be payable only at an
office or agency located outside the United States.

     Upon the issuance of any new Security under this Section, the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Security of any series with its coupons, if any, issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security or in exchange
for a Security to which a destroyed, lost or stolen coupon appertains, shall
constitute an original additional contractual obligation of the Company, whether
or not the destroyed, lost or stolen Security and its coupons, if any, or the
destroyed, lost or stolen coupon shall be at any time enforceable by anyone, and
any such new Security and coupons, if any, shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Securities
of that series and their coupons, if any, duly issued hereunder.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities or coupons.

SECTION 3.07   Payment of Interest; Interest Rights Preserved.

                                      -25-
<PAGE>

     Unless otherwise provided as contemplated by Section 301 with respect to
any series of Securities, interest on any Registered Security which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest. Unless otherwise so provided, at the option of the Company,
payment of interest on any Registered Security may be made by check mailed on or
before the due date to the address of the Person entitled thereto as such
address shall appear in the Security Register.

     Any interest on any Registered Security of any series which is payable, but
is not punctually paid or duly provided for, on any Interest Payment Date
(herein called "Defaulted Interest") shall forthwith cease to be payable to the
Holder on the relevant Regular Record Date by virtue of having been such Holder,
and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

          (1)  The Company may elect to make payment of any Defaulted Interest
to the Persons in whose names the Registered Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing
of the amount of Defaulted Interest proposed to be paid on each Registered
Security of such series and the date of the proposed payment, and at the same
time the Company shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or
shall make arrangements satisfactory to the Trustee for such deposit prior to
the date of the proposed payment, such money when deposited to be held in trust
for the benefit of the Persons entitled to such Defaulted Interest as in this
Clause provided. Thereupon the Trustee shall fix a Special Record Date for the
payment of such Defaulted Interest which shall be not more than 15 days and not
less than 10 days prior to the date of the proposed payment and not less than 10
days after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Company of such Special Record Date and, in
the name and at the expense of the Company, shall cause notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor to be
mailed, first-class postage prepaid, to each Holder of Registered Securities of
such series at the address of such Holder as it appears in the Security
Register, not less than 10 days prior to such Special Record Date. The Trustee
may, in its discretion, in the name and at the expense of the Company, cause a
similar notice to be published at least once in an Authorized Newspaper,
PROVIDED such publication shall not be a condition precedent to the
establishment of such Special Record Date. Notice of the proposed payment of
such Defaulted Interest and the Special Record Date therefor having been so
mailed, such Defaulted Interest shall be paid to the Persons in whose names the
Registered Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date
and shall no longer be payable pursuant to the following clause (2).

          (2)  The Company may make payment of any Defaulted Interest on the
Registered Securities of any series in any other lawful manner not inconsistent
with the requirements of any securities exchange on which such Securities may be
then listed, and upon such notice as may be required by such exchange, if, after
notice given by the Company to the Trustee of the proposed payment pursuant to
this Clause, such manner of payment shall be deemed practicable by the Trustee.

                                      -26-
<PAGE>

     Subject to the foregoing provisions of this Section and Section 305, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 3.08   Persons Deemed Owners.

     Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 305 and 307) any
interest on such Registered Security and for all other purposes whatsoever,
whether or not such Security be overdue, and none of the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.

     Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Company, the Trustee and any agent of the Company or the
Trustee may treat the bearer of any Bearer Security and the bearer of any coupon
as the owner of such Bearer Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Security or coupon be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

     Notwithstanding the foregoing, with respect to any Book-Entry Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by a Depository or impair, as between a
Depository and holders of beneficial interests in any Book-Entry Security, the
operation of customary practices governing the exercise of the rights of the
Depository (or its nominee) as Holder of such Book-Entry Security.

SECTION 3.09   Cancellation.

     All Securities and coupons surrendered for payment, redemption,
registration of transfer or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee. All Registered Securities and matured coupons so delivered shall
be promptly cancelled by the Trustee. All Bearer Securities and unmatured
coupons so delivered shall be held by the Trustee and, upon instruction by a
Company Order, shall be cancelled or held for reissuance. Bearer Securities and
unmatured coupons held for reissuance may be reissued only in replacement of
mutilated, lost, stolen or destroyed Bearer Securities of the same series and
like tenor or the related coupons pursuant to Section 306. All Bearer Securities
and unmatured coupons held by the Trustee pending such cancellation or
reissuance shall be deemed to be delivered for all purposes of this Indenture
and the Securities. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to
the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly
cancelled by the Trustee. No Securities shall be authenticated in lieu of or in

                                      -27-
<PAGE>

exchange for any Securities cancelled as provided in this Section, except as
expressly permitted by this Indenture. All cancelled Securities and coupons held
by the Trustee shall be disposed of in accordance with its customary practice.

SECTION 3.10   Computation of Interest.

     Except as otherwise specified as contemplated by Section 301 for Securities
of any series, interest on the Securities of each series shall be computed on
the basis of a 360-day year of twelve 30-day months.

                                  ARTICLE IV
                          SATISFACTION AND DISCHARGE

SECTION 4.01   Satisfaction and Discharge of Indenture.

     This Indenture shall upon Company Request cease to be of further effect
with respect to Securities of a Series (except as to any surviving rights of
registration of transfer or exchange of Securities herein expressly provided
for, and any right to receive additional amounts, as provided in Section 1004),
and the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture with respect to
Securities of a Series, when

               (1)  either

                    (A)  all Securities of such Series theretofore authenticated
and delivered and all coupons, if any, appertaining thereto (other than (i)
coupons appertaining to Bearer Securities surrendered for exchange for
Registered Securities and maturing after such exchange, whose surrender is not
required or has been waived as provided in Section 305, (ii) Securities and
coupons which have been destroyed, lost or stolen and which have been replaced
or paid as provided in Section 306, (iii) coupons appertaining to Securities
called for redemption and maturing after the relevant Redemption Date, whose
surrender has been waived as provided in Section 1106, and (iv) Securities and
coupons for whose payment money has 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 1003) have been delivered
to the Trustee for cancellation; or

                    (B)  with respect to all such Securities and, in the case of
(i) or (ii) below, any coupons appertaining thereto not theretofore delivered to
the Trustee for cancellation

                         (i)    have become due and payable, or

                         (ii)   will become due and payable at their Stated

redemption by the Trustee in the name, and at the expense, of the Company;

                                      -28-
<PAGE>

and the Company, in the case of (i), (ii) or (iii) above, has deposited or
caused to be deposited with the Trustee as trust funds in trust for the purpose
an amount sufficient to pay and discharge the entire indebtedness on such
Securities and coupons not theretofore delivered to the Trustee for
cancellation, for principal (and premium, if any) and any interest to the date
of such deposit (in the case of Securities which have become due and payable) or
to the Stated Maturity or Redemption Date, as the case may be;

          (2)  the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and

          (3)  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 have
been complied with.

obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to clause (1)(B) of this Section,
the obligations of the Company under Sections 306, 610(e) and 701 and the
obligations of the Trustee under Section 402 and the last paragraph of Section
1003 shall survive.

SECTION 4.02   Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 1003, all money
deposited with the Trustee pursuant to Section 401 shall be held in trust and
applied by it, in accordance with the provisions of the Securities, the coupons
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 has been deposited.

substantial part of the property of the Company, or the making by the Company of
an assignment for the benefit of creditors, or the admission by the Company in
writing of its inability to pay its debts generally as they become due, or the
taking of corporate action by the Company in furtherance of any such action; or

          (8)  any other Event of Default provided with respect to Securities of
that series.

SECTION 5.02   Acceleration of Maturity, Rescission and Annulment.

     If an Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal

                                      -30-
<PAGE>

amount of the Outstanding Securities of that series may declare the principal
amount (or, if any of the Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified in the terms thereof) of all of the Securities of that series to be
due and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by Holders), and upon any such declaration such principal
amount (or specified amount) shall become immediately due and payable.

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

          (1)  the Company has paid or deposited with the Trustee a sum
sufficient to pay

               (A)  all overdue interest on, and any additional amounts payable
as set forth in Section 1004 on, all Securities of that series and any coupons
appertaining thereto,

               (B)  the principal of (and premium, if any, on) any Securities of
that series which have become due otherwise than by such declaration of
acceleration and any interest thereon at the rate or rates prescribed therefor
in such Securities,

               (C)  to the extent that payment of such interest is lawful,
interest upon overdue interest, and any additional amounts payable as set forth
in Section 1004 on, at the rate or rates prescribed therefor in such Securities,
and

               (D)  all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel;

and

          (2)  all Events of Default with respect to Securities of that series,
other than the non-payment of the principal of Securities of that series which
have become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 513.

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

SECTION 5.03   Collection of Indebtedness and suits for Enforcement by Trustee.

     The Company covenants that if

          (1)  default is made in the payment of any interest on any Security
when such interest becomes due and payable and such default continues for a
period of 30 days, or

          (2)  default is made in the payment of the principal of (or premium,
if any, on) any Security at the Maturity thereof,

                                      -31-
<PAGE>

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities and coupons, the whole amount then due and payable on
such Securities and coupons for principal and any premium and interest and, to
the extent that payment of such interest shall be legally enforceable, interest
on any overdue principal and premium and on any overdue interest, at the rate or
rates prescribed therefor in such Securities (or, in the case of Original Issue
Discount Securities, the Securities' yield to maturity) and, in addition
thereto, 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.

     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.

     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series and any
related coupons by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 5.04   Trustee May File Proofs of Claim.

     In case of any judicial proceeding relative to the Company (or any other
obligor upon the Securities), or the property or the creditors of the Company,
the Trustee shall be entitled and empowered, by intervention in such proceeding
or otherwise, to take any and all actions authorized under the Trust Indenture
Act in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official 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 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 607.

     No provision of this Indenture shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; PROVIDED, HOWEVER,
that the Trustee may, on behalf of Holders, vote for the election of a trustee
of bankruptcy or similar official and be a member of a creditors' or other
similar committee.

SECTION 5.05   Trustee May Enforce Claims Without Possession of Securities or
Coupons.

                                      -32-
<PAGE>

     All rights of action and claims under this Indenture or the Securities or
coupons may be prosecuted and enforced by the Trustee without the possession of
any of the Securities or coupons or the production thereof in any proceeding
relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Securities and coupons in respect
of which such judgment has been recovered.

SECTION 5.06   Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any premium
or interest, upon presentation of the Securities or coupons, or both as the case
may be, and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 607; and

     SECOND: To the payment of the amounts then due and unpaid for principal of
and any premium and interest on the Securities and coupons in respect of which
or for the benefit of which such money has been collected, ratably, without
preference or priority of any kind, according to the amounts due and payable on
such Securities and coupons for principal and any premium and interest,
respectively.

     THIRD: The balance, if any, to the Person or Persons entitled thereto.

     In any case in which Securities are Outstanding that are denominated in
more than one currency and the Trustee is directed to make ratable payments
under this Section to Holders of such Securities, unless otherwise provided with
respect to any series of Securities, the Trustee shall calculate the amount of
such payments as follows: (i) as of the day the Trustee collects an amount under
this Article, the Trustee shall, as to each Holder of a Security to whom an
amount is due and payable under this Section that is denominated in a foreign
currency, determine that amount in Dollars that would be obtained for the amount
owing such Holder, using the rate of exchange at which in accordance with normal
banking procedures the Trustee could purchase in The City of New York Dollars
with such amount owing; (ii) calculate the sum of all Dollar amounts determined
under (i) and add thereto any amounts due and payable in Dollars; and (iii)
using the individual amounts determined in (i) or any individual amounts due and
payable in Dollars, as the case may be, as a numerator, and the sum calculated
in (ii) as a denominator, calculate as to each Holder of a Security to whom an
amount is owed under this Section the fraction of the amount collected under
this Article payable to such Holder. Any expenses incurred by the Trustee in
actually converting amounts owing Holders of Securities denominated in a
currency other than that in which any amount is collected under this Article
shall be likewise (in accordance with this paragraph) borne ratably by all
Holders of Securities to whom amounts are payable under this Section.

     To the fullest extent allowed under applicable law, if for the purpose of
obtaining judgment against the Company in any court it is necessary to convert
the sum due in respect of the principal

                                      -33-
<PAGE>

of, or premium, if any, or interest on, the Securities of any series (the
"Required Currency") into a currency in which a judgment will be rendered (the
"Judgment Currency"), the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The City
of New York the Required Currency with the Judgment Currency on the Business Day
in the City of New York next preceding that on which final judgment is given.
Neither the Company nor the Trustee shall be liable for any shortfall nor shall
it benefit from any windfall in payments to Holders of Securities under this
Section caused by a change in exchange rates between the time the amount of a
judgment against the Company is calculated as above and the time the Trustee
converts the Judgment Currency into the Required Currency to make payments under
this Section to Holders of Securities, but payment of such judgment shall
discharge all amounts owed by the Company on the claim or claims underlying such
judgment.

SECTION 5.07   Limitation on Suits.

     No Holder of any Security of any series or any related coupons shall have
any right to institute any proceeding, judicial or otherwise, with respect to
this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

          (1)  such Holder has previously given written notice to the Trustee of
a continuing Event of Default with respect to the Securities of that series;

          (2)  the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default in its own
name as Trustee hereunder;

          (3)  such Holder or Holders have offered to the Trustee reasonable
indemnity against the costs, expenses and liabilities to be incurred in
compliance with such request;

          (4)  the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity has failed to institute any such proceeding; and

          (5)  no direction inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all such
Holders.

SECTION 5.08   Unconditional Right of Holders to Receive Principal, Premium and
               Interest.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security or coupon shall have the right, which is absolute and unconditional, to
receive payment of the principal of and any premium and (subject to Sections 305
and 307) any interest on such Security or payment of such coupon on the Stated
Maturity or Maturities expressed in such Security or coupon (or, in the case

                                      -34-
<PAGE>

of redemption, on the Redemption Date) and to institute suit for the enforcement
of any such payment, and such rights shall not be impaired without the consent
of such Holder.

SECTION 5.09   Restoration of Rights and Remedies.

     If the Trustee or any Holder of a Security or coupon has instituted any
proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case, subject to any determination in such proceeding, the Company, the Trustee
and the Holders of Securities and coupons shall be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

SECTION 5.10   Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities or coupons in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders of Securities or coupons is intended to be exclusive
of any other right or remedy, and every right and remedy shall, to the extent
permitted by law, be cumulative and in addition to every other right and remedy
given hereunder or now or hereafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise,
shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

SECTION 5.11   Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Security or
coupon to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to the Holders of Securities or coupons may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders of Securities or coupons, as the case may be.

SECTION 5.12   Control by Holders of Securities.

     The Holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, with respect to the Securities of
such series, provided that

          (1)  such direction shall not be in conflict with any rule of law or
with this Indenture;

          (2)  the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction; and

                                      -35-
<PAGE>

          (3)  the Trustee shall not be obligated to take any action unduly
prejudicial to Holders not joining in such direction or involving the Trustee in
personal liability.

SECTION 5.13   Waiver of Past Defaults.

     The Holders of a majority in principal amount of the Outstanding Securities
of any series may on behalf of the Holders of all the Securities of such series
waive any past default hereunder with respect to the Securities of such series
and its consequences, except a default

          (1)  in the payment of the principal of or any premium or interest on
any Security of such series, or

          (2)  in respect of a covenant or provision hereof which under Article
Nine cannot be modified or amended without the consent of the Holder of each
Outstanding Security of such series affected.

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

SECTION 5.14   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, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust

     Indenture Act; PROVIDED that neither this Section nor the Trust Indenture
Act shall be deemed to authorize any court to require such an undertaking or to
make such an assessment in any suit instituted by the Company.

SECTION 5.15   Waiver of Stay or Extension Laws.

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim to
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                  ARTICLE VI
                                  THE TRUSTEE

                                      -36-
<PAGE>

     The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

SECTION 6.02   Notice of Defaults.

     If a default occurs hereunder with respect to Securities of any series, the
Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
501(5) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event which is, or after
notice or lapse of time or both would become, an Event of Default with respect
to Securities of such series.

SECTION 6.03   Certain Rights of Trustee.

     Subject to the provisions of Section 601:

          (1)  the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document believed by it
to be genuine and to have been signed or presented by the proper party or
parties;

          (2)  any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order and any resolution
of the Board of Directors of the Company shall be sufficiently evidenced by a
Board Resolution of the Company;

          (3)  whenever in the administration of this Indenture the Trustee
shall deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;

          (4)  the Trustee may consult with counsel and the written advice of
such counsel or any Opinion of Counsel shall be full and complete authorization
and protection in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon;

          (5)  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 pursuant to this Indenture, unless such Holders shall have
offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which might be incurred by it in compliance with such
request or direction;

                                      -37-
<PAGE>

          (6)  the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the
Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney;
and

          (7)  the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder.

SECTION 6.04   Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities (except the Trustee's
certificates of authentication) and in any coupons shall be taken as the
statements of the Company and the Trustee or any Authenticating Agent assumes no
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities or coupons.
The Trustee or any Authenticating Agent shall not be accountable for the use or
application by the Company of Securities or the proceeds thereof.

SECTION 6.05   May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and coupons and, subject
to Sections 608 and 613, may otherwise deal with the Company with the same
rights it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.

SECTION 6.06   Money Held in Trust.

     Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.

SECTION 6.07   Compensation and Reimbursement.

     The Company agrees

          (1)  to pay to the Trustee from time to time reasonable compensation
for all services rendered by it hereunder (which compensation shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust);

          (2)  except as otherwise expressly provided herein, to reimburse the
Trustee and each predecessor Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by the Trustee in
accordance with any provision of this Indenture (including the

                                      -38-
<PAGE>

reasonable compensation and the expenses and disbursements of its agents and
counsel), except any such expense, disbursement or advance as may be
attributable to its negligence or bad faith; and

          (3)  to indemnify the Trustee and each predecessor Trustee for, and to
hold it harmless against, any loss, liability or expense incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of the trust or trusts hereunder, including the
costs and expenses of defending itself against any claim or liability in
connection with the exercise or performance of any of its powers or duties
hereunder.

     As security for the performance of the obligations of the Company under
this Section the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the benefit of the Holders of particular Securities.

     Any expenses and compensation for any services rendered by the Trustee
after the occurrence of an Event of Default specified in clause (6) or (7) of
Section 501 shall constitute expenses and compensation for services of
administration under all applicable federal or state bankruptcy, insolvency,
reorganization or other similar laws.

     The provisions of this Section shall survive the termination of this
Indenture.

SECTION 6.08   Disqualification; Conflicting Interests.

     If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture.

SECTION 6.09   Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States,
any State thereof or the District of Columbia, authorized under such laws to
exercise corporate trust powers, having a combined capital and surplus of at
least $50,000,000, subject to supervision or examination by Federal or State
authority. If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of said supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article. No obligor upon any Security
issued under this Indenture or a person directly or indirectly controlling,
controlled by or under common control with such obligor shall serve as Trustee
under this Indenture.

SECTION 6.10   Resignation and Removal; Appointment of Successor.

     (a)  No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

                                      -39-
<PAGE>

     (b)  The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

     (c)  The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Trustee and to the
Company.

     (d)  If at any time:

          (1)  the Trustee shall fail to comply with Section 608 after written
request therefor by the Company or by any Holder of a Security who has been a
bona fide Holder of a Security for at least six months, or

          (2)  the Trustee shall cease to be eligible under Section 609 and
shall fail to resign after written request therefor by the Company or by any
such Holder, or

          (3)  the Trustee shall become incapable of acting or shall be adjudged
a bankrupt or insolvent or a receiver of the Trustee or of its property shall be
appointed or a public officer shall take charge or control of the Trustee or of
its property or affairs for the purpose of rehabilitation, conservation or
liquidation,

then, in any case, (i) the Company by a Board Resolution may remove the Trustee
with respect to all Securities, or (ii) subject to Section 514, any Holder of a
Security who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

     (e)  If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of the Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all series and that at any time there shall be only one Trustee with respect
to the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 611, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect

bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series. Such court may thereupon, after such notice,
if any, as it may deem proper, appoint a successor Trustee.

     (f)  The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series in the manner
provided in Section 106. Each notice shall include the name of the successor
Trustee with respect to the Securities of such series and the address of its
Corporate Trust Office.

SECTION 6.11   Acceptance of Appointment by Successor.

     (a)  In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee, with like effect as
if originally named Trustee hereunder; but on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder. Any Trustee ceasing to act shall, nevertheless,
retain a prior lien upon all property or funds held or collected by such Trustee
to secure any amounts then due it pursuant to the provisions of Section 607.

     (b)  In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees as co-trustees of
the same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all
rights, powers, trusts and duties of the retiring

                                      -41-
<PAGE>

Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates; but, on request of the Company or
any successor Trustee, such retiring Trustee shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates.

     (c)  Upon request of any successor Trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section, as the case may be.

     (d)  No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article.

SECTION 6.12   Merger, Conversion, Consolidation or Succession to Business.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, PROVIDED such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

SECTION 6.13   Preferential Collection of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company (or
any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

SECTION 6.14   Appointment of Authenticating Agent.

     The Trustee may, by an instrument in writing, appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which may be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon original issue or upon exchange, registration of transfer or
partial redemption thereof or pursuant to Section 306, and Securities so
authenticated shall be entitled to the benefits of this Indenture and shall be
valid and obligatory for all purposes as if authenticated by the Trustee
hereunder. Wherever reference is made in this Indenture to the authentication
and delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States, any State thereof or the District of Columbia (or, if Bearer Securities,
organized and doing business under the laws of the country in which the Bearer
Securities are eligible), authorized

                                      -42-
<PAGE>

under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination
by Federal or State authority (or, if Bearer Securities, an authority of the
country in which the Bearer Securities are eligible). If such Authenticating
Agent publishes reports of condition at least annually, pursuant to law or to
the requirements of said supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of such Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or such Authenticating Agent. An Authenticating
Agent may, and if it shall cease to be eligible shall, resign at any time by
giving written notice thereof to the Trustee and to the Company. The Trustee may
at any time terminate the agency of an Authenticating Agent by giving written
notice thereof to such Authenticating Agent and to the Company. Upon receiving
such notice of resignation or upon such termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Registered Securities, if any, of the series with respect to which such
Authenticating Agent will serve, as their names and addresses appear in the
Security Register. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers, and
duties of its predecessor hereunder, with like effect as if originally named as
an Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payment, subject to the provisions
of Section 607.

     If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have been endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

     "This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.

and if the Company has an Affiliate eligible to be appointed as an
Authenticating Agent hereunder or the Trustee does not have an office capable of
authenticating Securities upon original issuance located in a Place of Payment
where the Company wishes to have Securities of such series authenticated upon
original issuance, the Trustee, if so requested by the Company in writing (which
writing need not comply with Section 102 and need not be accompanied by an
Opinion of Counsel), shall appoint in accordance with this Section an
Authenticating Agent (which, if so requested by the Company, shall be such
Affiliate of the Company) having an office in a Place of Payment designated by
the Company with respect to such series of Securities.

office or agency where any Registered Securities of that series may be
surrendered for registration of transfer, where Securities of that series may be
surrendered for exchange and where notices and demands to or upon the Company in
respect of the Securities of that series, and this Indenture may be served. The
Company will give prompt written notice to the Trustee and prompt notices to the
Holders as provided in Section 106 of the location, and any change in the
location, of any such office or agency. If at any time the Company shall fail to
maintain any such required office or agency in respect of any series of
Securities or shall fail to furnish the Trustee with the address thereof, such
presentations and surrenders of Securities of that series may be made and
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, except that Bearer Securities of that series and the related coupons
may be presented and surrendered for payment (including payment of any
additional amounts payable on Bearer Securities of that series pursuant to
Section 10.04) at any Paying Agent for such series located outside the United
States, and the Company hereby appoints the same as its agents to receive such
respective presentations, surrenders, notices and demands.

     No payment of principal, premium or interest on Bearer Securities shall be
made at any office or agency of the Company in the United States or by check
mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; PROVIDED, HOWEVER, that, if
the Securities of a series are denominated and payable in Dollars, payment of
principal of and any premium and interest on any Bearer Security (including any
additional amounts payable on Securities of such series pursuant to Section
1004) shall be made at the office of the Company's Paying Agent in the Borough
of Manhattan, The City of New York, if (but only if) payment in Dollars of the
full amount of such principal, premium, interest or additional amounts,

                                      -50-
<PAGE>

as the case may be, at all offices or agencies outside the United States
maintained for the purpose by the Company in accordance with this Indenture is
illegal or effectively precluded by exchange controls or other similar
restrictions.

     The Company may also from time to time designate one or more other offices
or agencies where Securities of one or more series 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 accordance with the requirements set forth above for Securities of any series
for such purposes. The Company will give prompt written notice to the Trustee
and the Holders of any such designation or rescission and of any other change in
the location of any such other office or agency.

SECTION 10.03  Money for Securities Payments to be Held in Trust.

     If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities and any coupons appertaining thereto, it will, on or
before each due date of the principal of and any premium or interest on any of
the Securities of that series, segregate and hold in trust for the benefit of
the Persons entitled thereto a sum sufficient to pay the principal and any
premium or interest so becoming due until such sums shall be paid to such
Persons or otherwise disposed of as herein provided and will promptly notify the
Trustee of its action or failure to so act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, on or prior to each due date of the principal of and any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay the principal and any premium or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure to so act.

     The Company will cause each Paying Agent for any series of Securities
(other than the Company or the Trustee) to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will (i) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and
(ii) during the continuance of any default by the Company (or any other obligor
upon the Securities of that series) in the making of any payment in respect of
the Securities of that series, and upon the written request of the Trustee,
forthwith pay to the Trustee all sums held in trust by such Paying Agent for
payment in respect of the Securities of that series.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

                                      -51-
<PAGE>

     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 any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal and any premium or interest has become due and payable
shall be paid to the Company on Company Request (unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property
law), or (if then held by the Company) shall be discharged from such trust; and
the Holder of such Security or any coupon appertaining thereto shall (unless
otherwise required by mandatory provisions of applicable escheat or abandoned or
unclaimed property law) thereafter, as an unsecured general 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 an Authorized
Newspaper in each Place of Payment, 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 publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

SECTION 10.04  Additional Amounts.

     If the Securities of a series provide for the payment of additional
amounts, the Company will pay to the Holder of any Security of such series or
any coupon appertaining thereto additional amounts as provided therein. Whenever
in this Indenture there is mentioned, in any context, the payment of the
principal of or any premium or interest on, or in respect of, any Security of
any series or payment of any related coupon or the net proceeds received on the
sale or exchange of any Security of any series, such mention shall be deemed to
include mention of the payment of additional amounts provided for in this
Section to the extent that, in such context, additional amounts are, were or
would be payable in respect thereof pursuant to the provisions of this Section
and express mention of the payment of additional amounts (if applicable) in any
provisions hereof shall not be construed as excluding additional amounts in
those provisions hereof where such express mention is not made.

     If the Securities of a series provide for the payment of additional
amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities (or if the Securities of that series will not bear
interest prior to Maturity, the first day on which a payment of principal and
any premium is made), and at least 10 days prior to each date of payment of
principal and any premium or interest if there has been any change with respect
to the matters set forth in the below-mentioned Officers' Certificate, the
Company will furnish the Trustee and the Company's principal Paying Agent or
Paying Agents, if other than the Trustee, with an Officers' Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of and any premium or interest on the Securities of that
series shall be made to Holders of Securities of that series or any related
coupons who are United States Aliens without withholding for or on account of
any tax, assessment or other governmental charge described in the Securities of
that series. If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Securities or coupons and the Company will
pay to the Trustee or such Paying Agent the additional amounts required by this
Section. The Company covenants to indemnify the Trustee and any Paying Agent
for, and to hold them harmless against, any loss, liability or expense
reasonably incurred without negligence or

                                      -52-
<PAGE>

bad faith on their part arising out of or in connection with actions taken or
omitted by any of them in reliance on any Officers' Certificate furnished
pursuant to this Section.

SECTION 10.05  Purchase of Securities by Company or Subsidiary.

     If and so long as the Securities of a series are listed on The
International Stock Exchange of the United Kingdom and the Republic of Ireland
Limited and such stock exchange shall so require, the Company will not, and will
not permit any of its Subsidiaries to, purchase any Securities of that series by
private treaty at a price (exclusive of expenses and accrued interest) which
exceeds 120% of the mean of the nominal quotations of the Securities of that
series as shown in The Stock Exchange Daily Official List for the last trading
day preceding the date of purchase.

SECTION 10.06  Limitation on Liens.

     (a)  The Company will not, nor will it permit any Principal Subsidiary to,
issue, assume or guarantee any indebtedness for money borrowed (hereinafter in
this Article Ten referred to as "Debt"), if such Debt is secured by a mortgage,
pledge, security interest or lien (any mortgage, pledge, security interest or
lien being hereinafter in this Article Ten referred to as a "mortgage" or
"mortgages") upon any Principal Property of the Company or any Principal
Subsidiary or upon any shares of stock or other equity interest or indebtedness
of any Principal Subsidiary (whether such Principal Property, shares of stock or
other equity interest or indebtedness is now owned or hereafter acquired),
without in any such case effectively providing, concurrently with the issuance,
assumption or guarantee of such Debt, that the Securities (together with, if the
Company shall so determine, any other indebtedness of or guaranteed by the
Company or such Principal Subsidiary ranking equally with the Securities then
outstanding and existing or thereafter created) shall be secured equally and
ratably with (or prior to) such Debt; PROVIDED, HOWEVER, that the foregoing
restriction shall not apply to:

          (1)  mortgages on property acquired, constructed or improved by the
Company or any Principal Subsidiary after the date of this Indenture which are
created or assumed contemporaneously with, or within 180 days after, such
acquisition (or in the case of property constructed or improved, after the
completion and commencement of commercial operation of such property, whichever
is later) to secure or provide for the payment of any part of the purchase price
of such property or the cost of such construction or improvement, it being
understood that if a commitment for such a financing is obtained prior to or
within such 180-day period, the applicable mortgage shall be deemed to be
included in this clause (1) whether or not such mortgage is created within such
180-day period; provided that in the case of any such construction or
improvement the mortgage shall not apply to any property theretofore owned by
the Company or any Principal Subsidiary, other than any theretofore unimproved
real property on which the property so constructed, or the improvement, is
located;

          (2)  mortgages on any property existing at the time of acquisition
thereof (including mortgages on any property acquired from a Person which is
consolidated with or merged with or into the Company or a Subsidiary of the
Company) and mortgages outstanding at the time any Person becomes a Subsidiary
of the Company that are not incurred in connection with such entity becoming a
Subsidiary of the Company;

                                      -53-
<PAGE>

          (3)  mortgages in favor of the Company or any Principal Subsidiary;

          (4)  mortgages in favor of the United States, any State, any foreign
country or any department, agency or instrumentality or political subdivision of
any such jurisdiction, to secure partial, progress, advance or other payments
pursuant to any contract or statute or to secure any indebtedness incurred for
the purpose of financing all or any part of the purchase price or the cost of
constructing or improving the property subject to such mortgages, including,
without limitation, mortgages to secure Debt of the pollution control or
industrial revenue bond type;

          (5)  mortgages on any Principal Property held, leased or used by the
Company or any Principal Subsidiary in connection with the exploration for,
development of, or production of (but not the gathering, processing,
transportation or marketing of) natural gas, oil or other minerals; and

          (6)  any extension, renewal or replacement (or successive extensions,
renewals or replacements), in whole or in part, of any mortgage referred to in
any of the foregoing clauses (1), (2), (3), (4) and (5); PROVIDED, HOWEVER, that
the principal amount of Debt secured thereby shall not exceed the principal
amount of Debt so secured at the time of such extension, renewal or replacement,
and that such extension, renewal or replacement shall be limited to all or a
part of the property which secured the mortgage so extended, renewed or replaced
(plus improvements on such property).

     (b)  Notwithstanding the provisions of subsection (a) of this Section 1006,
the Company and any Principal Subsidiary may issue, assume or guarantee secured
Debt, which would otherwise be subject to the foregoing restrictions, in an
aggregate amount which, together with all other such Debt does not exceed 15% of
Net Tangible Assets, as shown on a consolidated balance sheet, as of a date not
more than 90 days prior to the proposed transaction, prepared by the Company in
accordance with generally accepted accounting principles.

SECTION 10.07  Statement by Officer as to Default.

     (a)  The Company shall deliver to the Trustee, within 120 days after the
end of each fiscal year of the Company ending after the date hereof, a brief
certificate from the principal executive officer, principal financial officer or
principal accounting officer as to his or her knowledge of the Company's
compliance with all conditions and covenants under this Indenture. For purposes
of this Section 1007, such compliance shall be determined without regard to any
period of grace or requirement of notice under this Indenture. Such certificate
shall comply with Section 314(a)(4) of the Trust Indenture Act.

     (b)  The Company shall, so long as any of the Securities are outstanding,
deliver to the Trustee forthwith upon any Officer becoming aware of any Event of
Default or event which, after notice or lapse of time or both, would become an
Event of Default, an Officers' Certificate specifying such Event of Default or
event and what action the Company proposes to take with respect thereto.

SECTION 10.08  Waiver of Certain Covenants.

                                      -54-
<PAGE>

     The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Section 1005, 1006 or Article Fifteen with
respect to the Securities of any series if before the time for such compliance
the Holders of a majority in principal amount of the Outstanding Securities of
such series shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition
except to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

                                  ARTICLE XI
                           REDEMPTION OF SECURITIES

SECTION 11.01  Applicability of Article.

     Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 301 for Securities of any series) in
accordance with this Article.

SECTION 11.02  Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution. In the case of any redemption at the election of the Company
of less than all the Securities of any series, the Company shall, at least 45
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities of such series to be redeemed. In
the case of any redemption of Securities (i) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, or (ii) pursuant to an election of the Company
which is subject to a condition specified in the terms of such Securities, the
Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction or condition.

SECTION 11.03  Selection of Securities to be Redeemed.

     If less than all the Securities of any series are to be redeemed (unless
all of the Securities of such series of a specified tenor are to be redeemed)
the particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Registered Securities of such series of a denomination larger than the
minimum authorized denomination for Securities of that series or of the
principal amount of global Securities of such series. If less than all of the
Securities of such series and of a specified tenor are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series and specified tenor not previously called for redemption in
accordance with the preceding sentence.

                                      -55-
<PAGE>

     The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed. For all purposes of
this Indenture, unless the context otherwise requires, all provisions relating
to the redemption of Securities shall relate, in the case of any Securities
redeemed or to be redeemed only in part, to the portion of the principal amount
of such Securities which has been or is to be redeemed.

SECTION 11.04  Notice of Redemption.

     Notice of redemption shall be given in the manner provided in Section 106
to the Holders of Securities to be redeemed not less than 30 nor more than 60
days prior to the Redemption Date.

     All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

          (3)  if less than all the Outstanding Securities of any series are to
be redeemed, the identification (and, in the case of partial redemption of any
Securities, the principal amounts) of the particular Securities to be redeemed,
and that on and after the Redemption Date, upon surrender of the Securities, new
Securities of such series in principal amount equal to the unredeemed part
thereof will be issued,

          (4)  that on the Redemption Date the Redemption Price will become due
and payable upon each such Security to be redeemed and, if applicable, that
interest thereon will cease to accrue on and after said date,

          (5)  (5) the place or places where such Securities, together in the
case of Bearer Securities with all coupons appertaining thereto, if any,
maturing after the Redemption Date, are to be surrendered for payment of the
Redemption Price, and

          (6)  that the redemption is for a sinking fund, if such is the case.

A notice of redemption published as contemplated by Section 106 need not
identify particular Registered Securities to be redeemed.

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

SECTION 11.05  Deposit of Redemption Price.

     On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and

                                      -56-
<PAGE>

(except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities which are to be redeemed on that date.

SECTION 11.06  Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest and the coupons for such
interest appertaining to any Bearer Securities so to be redeemed, except to the
extent provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with accrued interest to
the Redemption Date; PROVIDED, HOWEVER, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only at an office or agency located outside the United States (except as
otherwise provided in Section 1002) and, unless otherwise specified as
contemplated by Section 301, only upon presentation and surrender of coupons for
such interest, and PROVIDED, FURTHER, that, unless otherwise specified as
contemplated by Section 301, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.

     If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing coupons, or the surrender of such missing coupon or
coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to the Trustee or any Paying Agent any such missing coupon in respect of which a
deduction shall have been made from the Redemption Price, such Holder shall be
entitled to receive the amount so deducted; PROVIDED, HOWEVER, that interest
represented by coupons shall be payable only at an office or agency located
outside the United States (except as otherwise provided in Section 1002) and,
unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of those coupons.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security or, in the case of Original Issue Discount Securities, the Securities'
yield to maturity.

SECTION 11.07  Securities Redeemed in Part.

     Any Registered Security which is to be redeemed only in part shall be
surrendered at a Place of Payment thereof (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by,

                                      -57-
<PAGE>

the Holder thereof or his attorney duly authorized in writing), and the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Registered Security or Securities of
the same series and of like tenor, 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 Security so surrendered.

                                  ARTICLE XII
                                 SINKING FUNDS

SECTION 12.01  Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment." If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 1202. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series.

SECTION 12.02  Satisfaction of Sinking Fund Payments With Securities.

     The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption), together in the case of any Bearer
Securities of such series with all unmatured coupons appertaining thereto, and
(2) may apply as a credit Securities of a series which have been redeemed either
at the election of the Company pursuant to the terms of such Securities or
through the application of permitted optional sinking fund payments pursuant to
the terms of such Securities, in each case in satisfaction of all or any part of
any sinking fund payment with respect to the Securities of such series required
to be made pursuant to the terms of such Securities as provided for by the terms
of such series; PROVIDED that such Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by the
Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

SECTION 12.03  Redemption of Securities for Sinking Fund.

     Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee a Company Order
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
credited. Not less than 45 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment

                                      -58-
<PAGE>

date in the manner specified in Section 1103 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the
manner provided in Section 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

                                 ARTICLE XIII
                      DEFEASANCE AND COVENANT DEFEASANCE

SECTION 13.01  Company's Option to Effect Defeasance or Covenant Defeasance.

Article Thirteen.

SECTION 13.02  Defeasance and Discharge.

     Upon the Company's exercise of the option provided in Section 1301
applicable to this Section, the Company shall be deemed to have been discharged
from its obligations with respect to the Outstanding Securities of any series on
the date the conditions set forth below are satisfied (hereinafter,
"defeasance"). For this purpose, such defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by the
Outstanding Securities of such series and to have satisfied all its other
obligations under the Securities of such series and this Indenture insofar as
the Securities of such series are concerned (and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging the same), except
for the following which shall survive until otherwise terminated or discharged
hereunder: (A) the rights of Holders of the Securities of such series to
receive, solely from the trust fund described in Section 1304 and as more fully
set forth in such Section, payments in respect of the principal of and any
premium and interest on the Securities of such series when such payments are

Sections 304, 305, 306, 1002, 1003 and 1004, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (D) this Article Thirteen.
Subject to compliance with this Article Thirteen, the Company may exercise its
option under this Section 1302 notwithstanding the prior exercise of its option
under Section 1303.

SECTION 13.03  Covenant Defeasance.

applicable to this Section, (i) the Company shall be released from its
obligations with respect to the Securities of such series under Sections 801,
1005 and 1006 and (ii) the occurrence of an event specified in Sections 501(3)
or (5) shall not be deemed to be an Event of Default on and after the date the
conditions set forth below are satisfied (hereinafter, "covenant defeasance"),
but the remainder of this Indenture and such Securities shall be unaffected
thereby. For this purpose, such covenant defeasance means that 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 Section or clause whether directly
or indirectly by reason of any reference elsewhere herein to any such Section or

provision herein or in any other document, but the remainder of this Indenture
and such Securities shall be unaffected thereby.

SECTION 13.04  Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to application of either Section 1302
or Section 1303 to the then Outstanding Securities of any series:

          (1)  The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 609 who shall agree to comply with the provisions of this Article
Thirteen 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 benefit of the Holders of the Securities of such series, (A) money in an
amount, or (B) U.S. Government Obligations 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, sufficient, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, to pay and discharge, and which
shall be applied by the Trustee (or other qualifying trustee) to pay and
discharge, the principal of (and premium, if any) and each installment of
interest on the Securities and any coupons pertaining thereto on the Stated
Maturity of such principal (and premium, if any) or installment of interest in
accordance with the terms of this Indenture and of the Securities of such
series. For this purpose, "U.S. Government Obligations" means securities that
are (x) direct obligations of the United States for the payment of which its
full faith and credit is pledged or (y) obligations of a Person controlled or
supervised by and acting as an agency or instrumentality of the United States
the payment of which is unconditionally guaranteed as a full faith and credit
obligation by the United States, which, in either case, are not callable or
redeemable at the option of the issuer thereof, and shall also include a
depository receipt issued by a bank (as defined in Section 3(a)(2) of the
Securities Act of 1933, as amended) as custodian with respect to any such U.S.
Government Obligation or a specific payment of principal of or interest on any
such U.S. Government Obligation held by such custodian for the account of the
holder of such depository receipt, PROVIDED that (except as required by law)
such custodian is not authorized to make any deduction from the amount payable
to the holder of such depository receipt from any amount received by the
custodian in respect of the U.S. Government Obligation or the specific payment
of principal of or interest on the U.S. Government Obligation evidenced by such
depository receipt.

          (2)  In the case of an election under Section 1302, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (x) the Company
has received from, or there has been published by, the Internal Revenue Service
a ruling, or (y) since the date of this Indenture there has been a change in the
applicable United States Federal income tax law, in either case to the effect
that, and based thereon such opinion shall confirm that, the Holders of the
Outstanding Securities of such series will not recognize income, gain or loss
for United States Federal income tax purposes as a result of such deposit,
defeasance and discharge and will be subject to United States Federal income tax
on the same amounts, in the same manner and at the same times as would have been
the case if such deposit, defeasance and discharge had not occurred.

                                      -60-
<PAGE>

          (3)  In the case of an election under Section 1303, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of the Outstanding Securities of such series will not recognize gain or
loss for United States Federal income tax purposes as a result of such deposit
and covenant defeasance and will be subject to United States 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.

          (4)  No Event of Default or event which with notice or lapse of time
or both would become an Event of Default with respect to the Securities of such
series shall have occurred and be continuing on the date of such deposit or,
insofar as subsections 501(6) and (7) are concerned, at any time during the
period ending on the 121st day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until the
expiration of such period).

          (5)  Such defeasance or covenant defeasance shall not cause the
Trustee to have a conflicting interest within the meaning of the Trust Indenture
Act with respect to any securities of the Company.

          (6)  Such defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a default under, any other agreement or
instrument to which the Company is a party or by which it is bound.

          (7)  The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the defeasance under Section 1302 or
the covenant defeasance under Section 1303 (as the case may be) have been
complied with.

          (8)  Such defeasance or covenant defeasance shall not result in the
trust arising from such deposit constituting an investment company as defined in
the Investment Company Act of 1940, as amended, or such trust shall be qualified
under such Act or exempt from regulation thereunder.

SECTION 13.05  Deposited Money and U.S. Government Obligations to be Held in
               Trust; Other Miscellaneous Provisions.

     Subject to the provisions of the last paragraph of Section 1003, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee (or other qualifying trustee -- collectively, for purposes of this
Section 1305, the "Trustee") pursuant to Section 1304 in respect of the
Securities of such series shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities of such series 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 Holders of the Securities of such series, of all sums due and
to become due thereon in respect of principal (and premium, if any) and
interest, but such money need not be segregated from other funds except to the
extent required by law. The Company shall pay and indemnify the Trustee against
any tax, fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 1304 or the

                                      -61-
<PAGE>

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 the
Outstanding Securities.

     Anything in this Article Thirteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1304 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent defeasance or covenant
defeasance.

SECTION 13.06  Reinstatement.

     If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 1302 or 1303 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
Securities of such series shall be revived and reinstated as though no deposit
had occurred pursuant to this Article Thirteen until such time as the Trustee or
Paying Agent is permitted to apply all such money in accordance with Section
1302 or 1303; PROVIDED, HOWEVER, that if the Company makes any payment of
principal of or any premium or interest on any Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of the Securities of such series to receive such payment from the
money held by the Trustee or the Paying Agent.

<PAGE>

proposed to be taken at the meeting, and the Trustee shall not have made the
first publication of the notice of such meeting within 21 days after receipt of

SECTION 14.04  Quorum; Action.

     The Persons entitled to vote a majority in aggregate principal amount of

such notice need be given only once not less than five days prior to the date on
which the meeting is scheduled to be reconvened. Notice of the reconvening of an
adjourned meeting shall state expressly the percentage, as provided above, of
the aggregate principal amount of the Outstanding Securities of such series
which shall constitute a quorum.

     Except as limited by Section 512 or the proviso to the first paragraph of
Section 902, any resolution presented to a meeting (or adjourned meeting duly
reconvened at which a quorum is present as aforesaid) may be adopted by the
affirmative vote of the Holders of a majority in principal amount of the
Outstanding Bearer Securities of that series; provided, however, that any
resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other action which this Indenture expressly provides
may be made, given or taken by the Holders of a specified percentage, which is
less than a majority, in aggregate principal amount of the Outstanding Bearer
Securities of a series may be adopted at a meeting (or an adjourned meeting duly
reconvened and at which a quorum is present as aforesaid) by the affirmative
vote of the Holders of such specified percentage in principal amount of the
Outstanding Bearer Securities of that series.

passed or decision taken at any meeting of Holders of Bearer Securities of any
series duly held in accordance with this

<PAGE>

Section shall be binding on all the Holders of Securities of such series and the
related coupons, whether or not present or represented at the meeting.

SECTION 14.05  Determination of Voting Rights; Conduct and Adjournment of
               Meetings.

     (a)  Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Bearer Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Bearer Securities shall be proved in the manner specified in Section 104 and
the appointment of any proxy shall be proved in the manner specified in Section
104 or by having the signature of the Person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to
certify to the holding of Bearer Securities. Such regulations may provide that
written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 104 or other proof.

     (b)  The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Bearer Securities as provided in Section 1402(b), in
which case the Company or the Holders of Bearer Securities of the series calling
the meeting, as the case may be, shall in like manner appoint a temporary
chairman. A permanent chairman and a permanent secretary of the meeting shall be
elected by vote of the Persons entitled to vote a majority in aggregate
principal amount of the Outstanding Securities of such series represented at the
meeting.

     (c)  At any meeting each Holder of a Security of such series or proxy shall
be entitled to one vote for each $1,000 principal amount of the Outstanding
Securities of such series held or represented by him; provided, HOWEVER, that no
vote shall be cast or counted at any meeting in respect of any Bearer Security
challenged as not Outstanding and ruled by the chairman of the meeting to be not
Outstanding. The chairman of the meeting shall have no right to vote, except as
a Holder of a Security of such series or proxy.

     (d)  Any meeting of Holders of Bearer Securities of any series duly called
pursuant to Section 1402 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

SECTION 14.06  Counting Votes and Recording Action of Meetings.

Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting

                                      -64-
<PAGE>

their verified written reports in duplicate of all votes cast at the meeting. A
record, at least in duplicate, of the proceedings of each meeting of Holders of
Bearer Securities of any series shall be prepared by the secretary of the
meeting and there shall be attached to said record the original reports of the
inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more persons having knowledge of the facts setting forth a copy of the notice of
the meeting and showing that said notice was given as provided in Section 1402
and, if applicable, Section 1404. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

     This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.
