          THIS INDENTURE, dated as of September 26, 2000, is between NUEVO
ENERGY COMPANY, a Delaware corporation (hereinafter called the "Company"), any
SUBSIDIARY GUARANTORS (as defined hereinafter) that may become parties hereto
and STATE STREET BANK AND TRUST COMPANY, a Massachusetts trust company
(hereinafter called the "Trustee").

                            RECITALS OF THE COMPANY

          The Company has duly authorized the creation of a series of its debt
securities denominated as its 9 3/8% Senior Subordinated Notes due 2010, Series
A (the "Series A Securities") and a second series of such debt securities
denominated as its 9 3/8% Senior Subordinated Notes due 2010, Series B (the
"Series B Securities" and, together with the Series A Securities, the
"Securities"), of substantially the tenor and principal amounts hereinafter set
forth, and to provide therefor the Company has duly authorized the execution and
delivery of this Indenture.

          The Series A Securities are to be originally issued in an aggregate
principal amount of $150,000,000 on the date hereof pursuant to the Purchase
Agreement; additional Series A Securities may be originally issued from time to
time thereafter in an aggregate amount of up to $150,000,000; and Series B
Securities may also be originally issued from time to time hereafter, but only
in exchange for Series A Securities then outstanding, in each case pursuant to a
Registration Rights Agreement in an Exchange Offer.

          The Company shall cause each of its Restricted Subsidiaries (as
defined herein), prior to, or contemporaneously with, such Restricted
Subsidiary's incurrence of certain obligations as set forth in this Indenture,
to execute and deliver a supplement hereto pursuant to which such Restricted
Subsidiary shall agree to be bound by the terms of this Indenture, as if it were
an original party hereto, and to guarantee the Company's obligations under this
Indenture and the Securities, thereby becoming a Subsidiary Guarantor for
purposes of this Indenture.

          All things necessary have been done on the part of the Company to make
the Securities, when issued and executed by the Company and authenticated and
delivered by the Trustee as herein provided, the valid obligations of the
Company, in accordance with their respective terms.

          NOW, THEREFORE, THIS INDENTURE WITNESSETH:

          For and in consideration of the premises and the purchase of the
Securities by the Holders thereof, it is mutually covenanted and agreed, for the
equal and proportionate benefit of all Holders of the Securities, without
preference of one series of Securities over the other and without preference of
any Securities of one series over any other Securities of the same series as a
result of any different dates of their original issuance, as follows:

          Section 1.1  Definitions.
                       -----------

          "Acquired Indebtedness" means Indebtedness of a Person (a) assumed in
connection with an acquisition of Properties from such Person or (b) outstanding
at the time such Person becomes a Subsidiary of any other Person (other than any
Indebtedness incurred in connection with, or in contemplation of, such
acquisition or such Person becoming such a Subsidiary).  Acquired Indebtedness
shall be deemed to be incurred on the date of the related acquisition of
Properties from any Person or the date the acquired Person becomes a Subsidiary.

          "Act," when used with respect to any Holder, has the meaning specified
in Section 15.3.

          "Adjusted Consolidated Net Tangible Assets" means (without
duplication), as of the date of determination, (a) the sum of (i) discounted
future net cash flows from proved oil and gas reserves of the Company and its
Restricted Subsidiaries calculated in accordance with SEC guidelines but before
any state or federal income taxes, as estimated by a nationally recognized firm
of independent petroleum engineers in a reserve report prepared as of the end of
the Company's most recently completed fiscal year, as increased by, as of the
date of determination, the estimated discounted future net cash flows from (A)
estimated proved oil and gas reserves acquired since the date of such year-end
reserve report, and (B) estimated oil and gas reserves attributable to
extensions, discoveries and other additions and upward revisions of estimates of
proved oil and gas reserves since the date of such year-end reserve report due

       Section 2.3  Form of Reverse of Security.
                    ---------------------------

       This Security is one of a duly authorized issue of securities of the
Company designated as its  9 3/8% Senior Subordinated Notes due 2010, Series ___
(herein called the "Series ___ Securities" and, together with the Series ___
Securities, the "Securities"), limited (except as otherwise provided in the
Indenture referred to below) in aggregate principal amount to $300,000,000 at
any time Outstanding, which may be issued under an indenture (herein called the
"Indenture") dated as of September 26, 2000, between the Company and State
Street Bank and Trust Company (herein called the "Trustee," which term includes
any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties, obligations and immunities
thereunder of the Company, any Subsidiary Guarantors party thereto, the Trustee
and the Holders of the Securities, and of the terms upon which the Securities
are, and are to be, authenticated and delivered.

       The Indebtedness evidenced by the Securities is, to the extent and in
the manner provided in the Indenture, subordinate and subject in right of
payment to the prior payment in full of all Senior Indebtedness (as defined in
the Indenture) and this Security is issued subject to such provisions.  Each
Holder of this Security, by accepting the same, (i) agrees to and shall be bound
by such provisions, (ii) authorizes and directs the Trustee on his behalf to
take such action as may be necessary or appropriate to effectuate the
subordination as provided in the Indenture and (iii) appoints the Trustee as his
attorney-in-fact for such purpose.

       The Securities are subject to redemption, at the option of the Company,
in whole or in part, at any time on or after October 1, 2005, upon not less than
30 or more than 60 days' notice at the following Redemption Prices (expressed as
percentages of principal amount) set forth below if redeemed during the 12-month
period beginning October 1, of the years indicated below:

2008 and thereafter..................................   100.000%
</TABLE>

together in the case of any such redemption with accrued and unpaid interest, if
any, to the Redemption Date, all as provided in the Indenture.

       Notwithstanding the foregoing, prior to October 1, 2003 the Company may,
at any time or from time to time, redeem up to 33 1/3% of the aggregate
principal amount of the Securities originally issued (excluding, for this
purpose, any Securities issued in exchange for Series A Securities) at a
Redemption Price of 109.375% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the Redemption Date, with the net proceeds of one or
more Equity Offerings of the Company, provided that at least 66 2/3% of the
aggregate principal amount of the Securities originally issued (excluding, for
this purpose, any Series B Securities issued in exchange for Series A
Securities) remains Outstanding after the occurrence of such redemption and
provided, further, that such

                                      -32-
<PAGE>

redemption shall occur not later than 90 days after the date of the closing of
any such Equity Offering.

       In the case of any redemption of Securities, interest installments whose
Stated Maturity is on or prior to the Redemption Date will be payable to Holders
of such Securities, or one or more Predecessor Securities, of record at the
close of business on the relevant Record Date referred to on the face hereof.
Securities (or portions thereof) for whose redemption and payment provision is
made in accordance with the Indenture shall cease to bear interest from and
after the Redemption Date.

       The Securities do not have the benefit of any mandatory redemption or
sinking fund obligations.

       In the event of a Change of Control of the Company, and subject to
certain conditions and limitations provided in the Indenture, the Company will
be obligated to make an offer to purchase, on a Business Day not more than 60 or
less than 30 days following the mailing of a notice of the occurrence of a
Change of Control of the Company, all of the then Outstanding Securities at a
purchase price equal to 101% of the principal amount thereof, together with
accrued and unpaid interest to the Change of Control Purchase Date, all as
provided in the Indenture.

       In the event of Asset Sales, under certain circumstances, the Company
will be obligated to make a Net Proceeds Offer to purchase all or a specified
portion of each Holder's Securities at a purchase price equal to 100% of the
principal amount of the Securities, together with accrued and unpaid interest to
the Net Proceeds Payment Date.

       Holders of Securities that are the subject of an offer to purchase their
securities from the Company may elect to have such Securities purchased by
completing the form entitled "Option of Holder to Elect Purchase" below.

       As set forth in the Indenture, an Event of Default is generally (i)
failure to pay principal upon maturity, redemption or otherwise (including
pursuant to a Change of Control Offer or a Net Proceeds Offer); (ii) default for
30 days in payment of interest on any of the Securities; (iii) default in the
performance of agreements relating to mergers, consolidations and sales of all
or substantially all assets or the failure to make or consummate a Change of
Control Offer or a Net Proceeds Offer; (iv) failure for 60 days after notice to
comply with any other covenants in the Indenture, any Subsidiary Guarantee or
the Securities; (v) certain payment defaults under, and the acceleration prior
to the maturity of, certain Indebtedness of the Company or any Restricted
Subsidiary in an aggregate principal amount in excess of $10,000,000 (or
$40,000,000 in the case of Non-Recourse Purchase Money Indebtedness); (vi) the
failure of any Subsidiary Guarantee to be in full force and effect or otherwise
to be enforceable (except as permitted by the Indenture); (vii) certain final
judgments or orders against the Company or any Restricted Subsidiary in an
aggregate amount of more than $10,000,000 over the coverage under applicable
insurance policies which remain unsatisfied and either become subject to
commencement of enforcement proceedings or remain unstayed for a period of 60
days; and (viii) certain events of bankruptcy,

                                      -33-
<PAGE>

insolvency or reorganization of the Company or any Material Subsidiary. If any
Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in aggregate principal amount of the Outstanding Securities may
declare the principal amount of all the Securities to be due and payable
immediately, except that (i) in the case of an Event of Default arising from
certain events of bankruptcy, insolvency or reorganization of the Company or any
Material Subsidiary, the principal amount of the Securities will become due and
payable immediately without further action or notice, and (ii) in the case of an
Event of Default which relates to certain payment defaults or acceleration with
respect to certain Indebtedness, any such Event of Default and any consequential
acceleration of the Securities will be automatically rescinded if any such
Indebtedness is repaid or if the default relating to such Indebtedness is cured
or waived and if the holders thereof have accelerated such Indebtedness then
such holders have rescinded their declaration of acceleration. No Holder may
pursue any remedy under the Indenture unless the Trustee shall have failed to
act after notice from such Holder of an Event of Default and written request by
Holders of at least 25% in aggregate principal amount of the Outstanding
Securities, and the offer to the Trustee of indemnity reasonably satisfactory to
it; however, such provision does not affect the right to sue for enforcement of
any overdue payment on a Security by the Holder thereof. Subject to certain
limitations, Holders of a majority in aggregate principal amount of the
Outstanding Securities may direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Holders notice of any continuing default
(except default in payment of principal, premium or interest) if it determines
in good faith that withholding the notice is in the interest of the Holders. The
Company is required to file annual and quarterly reports with the Trustee as to
the absence or existence of defaults.

       The Indenture contains provisions for (i) defeasance at any time of the
entire indebtedness of the Company on this Security and (ii) discharge from
certain restrictive covenants and the related Defaults and Events of Default,
upon compliance by the Company with certain conditions set forth therein, which
provisions apply to this Security.

       The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and any Subsidiary Guarantors and the rights of the Holders under the
Indenture at any time by the Company, such Subsidiary Guarantors and the Trustee
with the consent of the Holders of a majority in aggregate principal amount of
the Securities at the time Outstanding.  The Indenture also contains provisions
permitting the Holders of specified percentages in aggregate principal amount of
the Securities at the time Outstanding, on behalf of the Holders of all the
Securities, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by or on behalf of the Holder of this Security shall
be conclusive and binding upon such Holder and upon all future Holders of this
Security and of any Security issued upon the registration of transfer hereof or
in exchange herefor or in lieu hereof whether or not notation of such consent or
waiver is made upon this Security.  Without the consent of any Holder, the
Company, any Subsidiary Guarantors and the Trustee may amend or supplement the
Indenture or the Securities to cure any ambiguity, defect or inconsistency, to
add or release any Subsidiary Guarantor pursuant to the Indenture, to provide
for uncertificated Securities in addition to or in place of certificated
Securities and to make certain other specified changes and other changes that do
not adversely affect the interests of any Holder in any material respect.

       No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any, on)
and interest on this Security at the times, place, and rate, and in the coin or
currency, herein prescribed.

                                      -34-

       As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registerable on the Security
Register of the Company, upon surrender of this Security for registration of
transfer at the office or agency of the Company maintained for such purpose duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities, of like tenor and of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

       The Securities are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the Securities
are exchangeable for a like aggregate principal amount of Securities of like
tenor and of a different authorized denomination, as requested by the Holder
surrendering the same.

       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 payable in connection therewith.

       A director, officer, employee, incorporator, stockholder or Affiliate of
the Company or any Subsidiary Guarantor, as such, past, present or future shall
not have any personal liability under this Security or the Indenture by reason
of his or its status as such director, officer, employee, incorporator,
stockholder or Affiliate, or any liability for any obligations of the Company or
any Subsidiary Guarantor under the Securities or the Indenture or for any claim
based on, in respect of, or by reason of such obligations or their creation.
Each Holder, by accepting this Security with the notation of Subsidiary
Guarantee endorsed hereon, waives and releases all such liability. Such waiver
and release are part of the consideration for the issuance of this Security with
the notation of Subsidiary Guarantee endorsed hereon.

       Prior to the time of due presentment of this Security for registration of
transfer, the Company, any Subsidiary Guarantors, the Trustee and any agent of
the Company or the Trustee may treat the Person in whose name this Security is
registered as the owner hereof for all purposes, whether or not this Security is
overdue, and neither the Company, any Subsidiary Guarantors, the Trustee nor any
agent shall be affected by notice to the contrary.

       All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture. The Company will furnish to
any Holder upon written request and without charge a copy of the Indenture.
Requests may be made to the Company at 1021 Main Street, Suite 2100, Houston,
Texas 77002.

       Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Securities as a convenience to the Holders thereof.  No
representation is made as to the accuracy of such numbers as printed on the
Securities and reliance may be placed only on the other identifying information
printed hereon.

       Interest on this Security shall be computed on the basis of a 360-day
year comprised of twelve 30-day months.

       Section 2.4  Form of Notation Relating to Subsidiary Guarantees.
                    --------------------------------------------------

       The form of notation to be set forth on each Security relating to the
Subsidiary Guarantees, if any, shall be in substantially the following form:

                             SUBSIDIARY GUARANTEES

       Subject to the limitations set forth in the Indenture, all Subsidiary
Guarantors (as defined in the Indenture referred to in the Security upon which
this notation is endorsed and each being hereinafter referred to as a
"Subsidiary Guarantor," which term includes any successor Subsidiary Guarantor
under the Indenture) that may become party to the Indenture after the execution
and delivery thereof, have, jointly and severally, unconditionally guaranteed
(a) the due and punctual payment of the principal (and

premium, if any) of and interest on the Securities, whether at maturity,
acceleration, redemption or otherwise, (b) the due and punctual payment of
interest on the overdue principal of and interest on the Securities, if any, to
the extent lawful, (c) the due and punctual performance of all other obligations
of the Company to the Holders or the Trustee, all in accordance with the terms
set forth in the Indenture, and (d) in case of any extension of time of payment
or renewal of any Securities or any of such other obligations, the same will be
promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, whether at Stated Maturity, by acceleration or otherwise.

       The obligations of each Subsidiary Guarantor are limited to the maximum
amount as will, after giving effect to all other contingent and fixed
liabilities of such Subsidiary Guarantor and after giving effect to any
collections from or payments made by or on behalf of any other Subsidiary
Guarantor in respect of the obligations of such other Subsidiary Guarantor under
its Subsidiary Guarantee or pursuant to its contribution obligations under the
Indenture, result in the obligations of such Subsidiary Guarantor under the
Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent
transfer under federal or state law.  Each Subsidiary Guarantor that makes a
payment or distribution under a Subsidiary Guarantee shall be entitled to a
contribution from each other Subsidiary Guarantor in a pro rata amount based on
the Adjusted Net Assets of each Subsidiary Guarantor.

       The obligations of the Subsidiary Guarantors to the Holders or the
Trustee pursuant to the Subsidiary Guarantees and the Indenture are expressly
subordinate to all Guarantor Senior Indebtedness to the extent set forth in
Article XIII of the Indenture and reference is made to such Indenture for the
precise terms of such subordination.

       No stockholder, officer, director, employee, incorporator or Affiliate as
such, past, present or future, of any Subsidiary Guarantor shall have any
personal liability under its Subsidiary Guarantee by reason of his or its status
as such stockholder, officer, director, employee, incorporator or Affiliate, or
any liability for any obligations of any Subsidiary Guarantor under the
Securities or the Indenture or for any claim based on, in respect of, or by
reason of such obligations or their creation.

       Any Subsidiary Guarantor may be released from its Subsidiary Guarantee
upon the terms and subject to the conditions provided in the Indenture.

       All terms used in this notation of Subsidiary Guarantee which are defined
in the Indenture referred to in this Security upon which this notation of
Subsidiary Guarantees is endorsed shall have the meanings assigned to them in
such Indenture.

       The Subsidiary Guarantees shall be binding upon the Subsidiary Guarantors
and shall inure to the benefit of the Trustee and the Holders and, in the event
of any transfer or assignment of rights by any Holder or the Trustee respecting
the Security upon which the foregoing Subsidiary Guarantees are noted, the
rights and privileges herein conferred upon that party shall automatically
extend to and be vested in such transferee or assignee, all subject to the terms
and conditions hereof and in the Indenture.

       The Subsidiary Guarantees shall not be valid or obligatory for any
purpose until the certificate of authentication on the Security upon which the
foregoing Subsidiary

                                      -38-

Guarantees are noted shall have been executed by the Trustee under the Indenture

                                THE SECURITIES

       Section 3.1  Title and Terms.
                    ---------------

       The aggregate principal amount of Series A Securities which may be
authenticated and delivered under this Indenture for original issue on the Issue
Date is limited to $150,000,000 (such Series A Securities being herein called
the "Offered Securities"), and from time to time after the Issue Date up to an
additional $150,000,000 aggregate principal amount of Series A Securities may be
issued, authenticated and delivered hereunder.  The aggregate principal amount
of Series B Securities which may be authenticated and delivered under this
Indenture for original issue is limited to $150,000,000.  The aggregate
principal amount of Securities Outstanding at any one time may not exceed
$300,000,000 except as provided in Section 3.7 hereof.

       The Series A Securities shall be known and designated as the "9 3/8%
Senior Subordinated Notes due 2010, Series A" of the Company. Their Stated
Maturity shall be October 1, 2010, and they shall bear interest at the rate of 9
3/8% per annum from the date of their original issuance, or from the most recent
Interest Payment Date to which interest has been paid or duly provided for,
payable semiannually on April 1 and October 1 in each year, commencing, in the
case of the Offered Securities, April 1, 2001, and at said Stated Maturity,
until the principal thereof is paid or duly provided for.

                                      -39-

       The Series B Securities shall be known and designated as the "9 3/8%
Senior Subordinated Notes due 2010, Series B" of the Company.  Their Stated
Maturity shall be October 1, 2010, and they shall bear interest at the rate of 9
3/8% per annum from the date of their original issuance, or from the most recent
Interest Payment Date to which interest has been paid or duly provided for,
payable semiannually on April 1 and October 1 in each year, commencing on the
first April 1 or October 1 following the original issuance of the Series B
Securities, and at said Stated Maturity, until the principal thereof is paid or
duly provided for.

       Upon the occurrence of a Registration Default, the interest rate on
Transfer Restricted Securities shall increase ("Special Interest"), with respect
to the first 90-day period immediately following the occurrence of such
Registration Default, by 0.50% per annum and shall increase by an additional
0.25% per annum with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of 1.0% per annum
with respect to all Registration Defaults.  Following the cure of a Registration
Default, the accrual of Special Interest with respect to such Registration
Default shall cease and upon the cure of all Registration Defaults the interest
rate shall revert to the original rate.  Any Special Interest due on any
Security shall be payable on the appropriate Interest Payment Date to the Holder
entitled to receive the interest payment to be made on such date.  Each
obligation to pay Special Interest shall be deemed to accrue from and including
the date of the first applicable Registration Default to but excluding the date
on which all Registration Defaults have been cured.

       Accrued but unpaid interest on any Series A Security that is exchanged
for a Series B Security pursuant to a Registration Rights Agreement shall be
paid on the first Interest Payment Date on the Series B Securities.

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

       As provided in the applicable Registration Rights Agreement and subject
to the limitations set forth therein, at the option of the Holders, the Series A
Securities shall be exchangeable for Series B Securities of like aggregate
principal amount pursuant to an Exchange Offer.

       The principal of (and premium, if any, on) and interest on the Securities
shall be payable at the office or agency of the Company maintained for such
purpose in The City of New York; provided, however, that, at the option of the
Company, interest may be paid on Physical Securities by check mailed on or
before the due date to addresses of the Persons entitled thereto as such
addresses shall appear on the Security Register.

       The Securities shall be subject to defeasance at the option of the
Company as provided in Article XII hereof.

       Section 3.3  Execution, Authentication, Delivery and Dating.
                    ----------------------------------------------

       The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its President or a Vice President of the Company, under its
corporate seal reproduced thereon and attested by its Secretary or an Assistant
Secretary of the Company. The signature of any of these officers on the
Securities may be manual or facsimile signatures of the present or any future
such authorized officer and may be imprinted or otherwise reproduced on the
Securities.

       Securities 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.

       At any time after the execution and delivery of this Indenture, the
Company may deliver Series A Securities executed by the Company (and if at such
time there are any Subsidiary Guarantors, then having the notations of
Subsidiary Guarantees executed by such Subsidiary Guarantors) to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Series A Securities, and the Trustee in accordance with such
Company Order shall authenticate and deliver such Series A Securities with the
notations of Subsidiary Guarantees, if any, thereon as provided in this
Indenture.  Such Company Order shall specify the principal amount of the Series
A Securities to be authenticated and the date on which the original issue of
Series A Securities is to be authenticated.  In addition, on or prior to the
date of consummation of any Exchange Offer, the Company may deliver Series B
Securities executed by the Company (and if at such time there are any Subsidiary
Guarantors, then having the notations of Subsidiary Guarantees executed by such
Subsidiary Guarantors) to the Trustee for authentication, together with a
Company Order for the authentication and delivery of such Series B Securities,
and the Trustee in accordance with such Company Order shall authenticate and
deliver such Series B Securities with the notations of Subsidiary Guarantees, if
any, thereon as provided in this Indenture.  Such Company Order shall specify
the principal amount of the Series B Securities to be authenticated and the date
on which the Series B Securities are to be exchanged for an equal principal
amount of Series A Securities.

       Each Security shall be dated the date of its authentication.

       No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein duly
executed by the Trustee by manual signature of an authorized signatory, and such
certificate upon any Security

                                      -41-
<PAGE>

shall be conclusive evidence, and the only evidence, that such Security has been
duly authenticated and delivered hereunder and is entitled to the benefits of
this Indenture.

       In case the Company, pursuant to and in compliance with Article VIII
hereof, shall be consolidated or merged with or into any other Person or shall
sell, convey, transfer, lease or otherwise dispose of all or substantially all
of its Properties to any Person, and the successor Person resulting from such
consolidation, or surviving such merger, or into which the Company shall have
been merged, or the Person which shall have received a sale, conveyance,
transfer, lease or other disposition as aforesaid, shall have executed an
indenture supplemental hereto with the Trustee pursuant to Article VIII hereof,
any of the Securities authenticated or delivered prior to such sale,
consolidation, merger, conveyance, transfer, lease or other disposition may,
from time to time, at the request of the successor Person be exchanged for other
Securities executed in the name of the successor Person with such changes in
phraseology and form as may be appropriate, but otherwise in substance of like
tenor as the Securities surrendered for such exchange and of like principal
amount; and the Trustee, upon Company Request of the successor Person, shall
authenticate and deliver Securities as specified in such request for the purpose
of such exchange. If Securities shall at any time be authenticated and delivered
in any new name of a successor Person pursuant to this Section in exchange or
substitution for or upon registration of transfer of any Securities, such
successor Person, at the option of the Holders but without expense to them,
shall provide for the exchange of all Securities at the time Outstanding for
Securities authenticated and delivered in such new name.

       Section 3.4  Temporary Securities.
                    --------------------

       Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued (and if at
such time there are any Subsidiary Guarantors, then having the notations of
Subsidiary Guarantees thereon) and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities
(and notations of Subsidiary Guarantees, if any) may determine, as conclusively
evidenced by their execution of such Securities (and notations of Subsidiary
Guarantees, if any).

       If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at the office
or agency of the Company designated for such purpose pursuant to Section 10.2
hereof, without charge to the Holder.  Upon surrender for cancellation of any
one or more temporary Securities, the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of like tenor and of authorized denominations (and if at
such time there are any Subsidiary Guarantors, then having the notations of
Subsidiary Guarantees thereon).  Until so exchanged, the temporary Securities
shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities.

       Section 3.5  Registration of Transfer and Exchange.
                    -------------------------------------

       The Company shall cause to be kept a register (the "Security Register")
in which, subject to such reasonable regulations as it may prescribe, the
Company shall provide for

                                      -42-
<PAGE>

the registration of Securities and of transfers of Securities. The Security
Register shall be in written form or any other form capable of being converted
into written form within a reasonable time. At all reasonable times and during
normal business hours, the Security Register shall be open to inspection by the
Trustee. The Trustee is hereby initially appointed as security registrar (the
"Security Registrar") for the purpose of registering Securities and transfers of
Securities as herein provided.

       Subject to the provisions of this Section 3.5 and Section 3.6 hereof,
upon surrender for registration of transfer of any Security at the office or
agency of the Company designated pursuant to Section 10.2 hereof, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Securities of like
tenor and of any authorized denominations and of a like aggregate principal
amount, each such Security having the notation of Subsidiary Guarantees thereon
if there are then any Subsidiary Guarantors.

       Furthermore, any Holder of a Global Security shall, by acceptance of such
Global Security, be deemed to have agreed that transfers of beneficial interests
in such Global Security may be effected only through a book-entry system
maintained by the Depository (or its agent), and that ownership of a beneficial
interest in a Global Security shall be required to be reflected in a book entry.

       At the option of any Holder, Securities may be exchanged for other
Securities of like tenor or of any authorized denomination and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
the office or agency of the Company designated pursuant to Section 10.2 hereof.
Further, at the option of any Holder, Series A Securities may be exchanged,
pursuant to an Exchange Offer and subject to the terms and conditions thereof,
for Series B Securities of like aggregate principal amount, upon surrender of
the Series A Securities to be exchanged at such office or agency.  Whenever any
Securities are so surrendered for exchange, the Company shall execute, the
Subsidiary Guarantors, if any, shall execute notations of Subsidiary Guarantees
on, and the Trustee shall authenticate and deliver, the Securities which the
Holder making the exchange is entitled to receive.

       All Securities and the Subsidiary Guarantees noted thereon, if any,
issued upon any registration of transfer or exchange of Securities shall be the
valid obligations of the Company and the respective Subsidiary Guarantors, if
any, 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 Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Security Registrar) be
duly endorsed, or be accompanied by a written instrument of transfer, in form
satisfactory to the Company and the Security Registrar, duly executed by the
Holder thereof or his attorney duly authorized in writing.  As a special
condition to registration of transfer or exchange of any Transfer Restricted
Securities involving removal of a Private Placement Legend (other than pursuant
to an effective registration statement under the Securities Act), the Holder
requesting such registration of transfer or exchange shall furnish the Opinion
of Counsel called for by Section 3.12 hereof.  The following additional special
conditions shall apply to the indicated types of transfers or exchanges:

                                      -43-
<PAGE>

          (a) Respecting any requested registration of transfer or exchange of
Transfer Restricted Securities in the form of Physical Securities, such Physical
Securities shall be accompanied, in the sole discretion of the Company, by the
following additional information and documents, as applicable:

          (1) if such Physical Security is being delivered to the Security
     Registrar by a Holder for registration in the name of such Holder, without
     transfer, a certification from such Holder to that effect (in substantially
     the form of Exhibit B hereto); or

          (2) if such Physical Security is being transferred to a Qualified
     Institutional Buyer in accordance with Rule 144A, a certification to that
     effect (in substantially the form of Exhibit B hereto); or

          (3) if such Physical Security is being transferred to an Institutional
     Accredited Investor, delivery of a certification to that effect (in
     substantially the form of Exhibit B hereto), a Transferee Certificate for
     Institutional Accredited Investors in the form of Exhibit C hereto and an
     Opinion of Counsel to the effect that such transfer is in compliance with
     the Securities Act; or

          (4) if such Physical Security is being transferred in reliance on
     Regulation S, delivery of a certification to that effect (substantially in
     the form of Exhibit B hereto), a Transferor Certificate for Regulation S
     Transfers in the form of Exhibit D hereto and an Opinion of Counsel to the
     effect that such transfer is in compliance with the Securities Act; or

          (5) if such Physical Security is being transferred in reliance on Rule
     144, delivery of a certification to that effect (substantially in the form
     of Exhibit B hereto) and an Opinion of Counsel to the effect that such
     transfer is in compliance with the Securities Act; or

          (6) if such Physical Security is being transferred in reliance on
     another exemption from the registration requirements of the Securities Act,
     a certification to that effect (in substantially the form of Exhibit B
     hereto) and an Opinion of Counsel to the effect that such transfer is in
     compliance with the Securities Act.

Any Physical Security issued upon any such registration of transfer or exchange
shall be in a minimum principal amount of $250,000.

          (b) Respecting any requested exchange of a Physical Security for a
beneficial interest in a Global Security, such Physical Security shall be
accompanied, in the sole discretion of the Company, by the following additional
information and documents:

          (1) a certification, substantially in the form of Exhibit B hereto,
     that such Physical Security is being transferred to a Person reasonably
     believed to be a Qualified Institutional Buyer; and

          (2) written instructions directing the Security Registrar to make, or
     to direct the Depository to make, an endorsement on the Global Security to
     reflect an

<PAGE>

     increase in the aggregate amount of the Securities represented by the
     Global Security;

whereupon the Security Registrar shall cancel such Physical Security and cause,
or direct the Depository to cause, in accordance with the standing instructions
and procedures existing between the Depository and the Security Registrar, the
aggregate principal amount of Securities represented by the Global Security to
be increased accordingly.  If no Global Security is then outstanding, the
Company shall issue and the Trustee shall upon Company Order authenticate a new
Global Security in the appropriate amount.

          (c) With the prior approval of the Company, any Person having a
beneficial interest in a Global Security may upon request to the Security
Registrar exchange such beneficial interest for a Physical Security.  Upon

instructions as is customary for the Depository) from the Depository or its
nominee on behalf of any Person having a beneficial interest in a Global
Security and upon receipt by the Security Registrar of a written order or such

designated by the Depository as having such a beneficial interest containing
registration instructions and, in the case of any such transfer or exchange of a
beneficial interest in Transfer Restricted Securities, the following additional

     hereto and an Opinion of Counsel to the effect that such transfer is in

     Transfers in the form of Exhibit D hereto and an Opinion of Counsel to the

then the Security Registrar will cause, in accordance with the standing
instructions and procedures existing between the Depository and the Security
Registrar, the aggregate principal amount of the Global Security to be reduced
and, following such reduction, the Company will execute and, upon receipt of a
Company Order, the Trustee will authenticate and deliver to the transferee a
Physical Security.  Securities issued in exchange for a beneficial interest in a
Global Security pursuant to this Section 3.5(c) shall be registered in such
names and in such authorized denominations as the Depository, pursuant to
instructions from Agent Members or otherwise, shall instruct the Security
Registrar in writing; provided, however, that any Transfer Restricted Security
shall be issued in a minimum denomination of $250,000.  The Security Registrar
shall deliver such Physical Securities to the Persons in whose names such
Physical Securities are so registered.

       No service charge shall be made for any registration of transfer or
exchange or redemption 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 an Exchange Offer or Section 3.4, 9.6 or 11.8 hereof
not involving any transfer.

       Neither the Trustee, the Security Registrar nor the Company shall be
required (i) to issue, register the transfer of or exchange any Physical
Security during a period beginning at the opening of business 15 days before the
mailing of a notice of redemption of Securities selected for redemption under
Section 11.4 hereof and ending at the close of business on the day of such
mailing of the relevant notice of redemption, or (ii) to register the transfer
of or exchange any Physical Security so selected for redemption in whole or in
part, except the unredeemed portion of any Physical Security being redeemed in
part.

       Section 3.6  Book-Entry Provisions for Global Securities.
                    -------------------------------------------

       Each Global Security shall (i) be registered in the name of the
Depository for such Global Security or the nominee of such Depository, (ii) be
delivered to the Trustee as custodian for such Depository and (iii) bear the
legend set forth in Exhibit A hereto.

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

       Transfers of a Global Security shall be limited to transfers of such
Global Security in whole, but not in part, to the Depository, its successors or
their respective nominees. Interests of beneficial owners in a Global Security
may be transferred or exchanged for Physical Securities in accordance with the
rules and procedures of the Depository and the provisions of Section 3.5 hereof.
In addition, Physical Securities shall be transferred to all

                                      -46-
<PAGE>

beneficial owners in exchange for their beneficial interests in a Global
Security if, and only if, either (1) the Depository notifies the Company that it
is unwilling or unable to continue as depositary for the Global Security and a
successor depositary is not appointed by the Company within 90 days of such
notice, or (2) an Event of Default has occurred and is continuing and the
Security Registrar has received a request from the Depository to issue Physical
Securities in lieu of all or a portion of the Global Security (in which case the
Company shall deliver Physical Securities within 30 days of such request).

       In connection with the transfer of an entire Global Security to
beneficial owners pursuant to this Section, the Global Security shall be deemed
to be surrendered to the Trustee for cancellation, and the Company shall
execute, and the Trustee shall upon Company Order authenticate and deliver, to
each beneficial owner identified by the Depository, in exchange for its
beneficial interest in the Global Security, an equal aggregate principal amount
of Physical Securities of authorized denominations.

       The Holder of the Global Security may grant proxies and otherwise
authorize any Person, including Agent Members and Persons that may hold
interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture or the Securities.

       Section 3.7  Mutilated, Destroyed, Lost and Stolen Securities.
                    ------------------------------------------------

       If (i) any mutilated Security is surrendered to the Trustee or (ii) the
Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and there is delivered to the
Company, the Subsidiary Guarantors, if any, and the Trustee such security or
indemnity as may be required by them to save each of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security has been
acquired by a bona fide purchaser, the Company shall execute, the Subsidiary
Guarantors, if any, shall execute the notation of Subsidiary Guarantees, and
upon Company Order the Trustee shall authenticate and deliver, in exchange for
any such mutilated Security or in lieu of any such destroyed, lost or stolen
Security, a new Security of like tenor and principal amount, having the notation
of Subsidiary Guarantees thereon if at such time there are any Subsidiary
Guarantors, bearing a number not contemporaneously outstanding.

       In case any such mutilated, destroyed, lost or stolen Security 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.

       Upon the issuance of any new Security under this Section, the Company may
require the 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 issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company and the respective Subsidiary
Guarantors, if any, whether or not the mutilated, destroyed, lost or stolen
Security shall be at any time enforceable by anyone, and shall be entitled to
all benefits of this Indenture equally and proportionately with any and all
other Securities of like tenor duly issued hereunder.

                                      -47-
<PAGE>

       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.

       Section 3.8  Payment of Interest; Interest Rights Preserved.
                    ----------------------------------------------

       Interest on any 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 such Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest at the office or
agency of the Company maintained for such purpose pursuant to Section 10.2
hereof.

       Any interest on any Security which is payable, but is not punctually paid
or duly provided for, on any Interest Payment Date shall forthwith cease to be
payable to the Holder on the Regular Record Date by virtue of having been such
Holder, and such defaulted interest and (to the extent lawful) interest on such
defaulted interest at the rate borne by the Securities (such defaulted interest
and interest thereon herein collectively called "Defaulted Interest") may be
paid by the Company, at its election in each case, as provided in clause (a) or
(b) below:

          (a) The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities (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 Security 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, and such
money when deposited shall 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 given in the
manner provided for in Section 15.5 hereof, not less than 10 days prior to such
Special Record Date. Notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor having been so given, such Defaulted
Interest shall be paid to the Persons in whose names the Securities (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 (b).

          (b) The Company may make payment of any Defaulted Interest in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be 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.

                                      -48-
<PAGE>

       Subject to the foregoing provisions of this Section, 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 3.9  Persons Deemed Owners.
                    ---------------------

       Prior to the due presentment of a Security for registration of transfer,
the Company, the Subsidiary Guarantors, if any, the Security Registrar, the
Trustee and any agent of the Company, the Subsidiary Guarantors, if any, or the
Trustee may treat the Person in whose name such Security is registered as the
owner of such Security for the purpose of receiving payment of principal of (and
premium, if any, on) and (subject to Section 3.8 hereof) interest on such
Security and for all other purposes whatsoever, whether or not such Security be
overdue, and none of the Company, the Subsidiary Guarantors, if any, the
Security Registrar, the Trustee or any agent of the Company, the Subsidiary
Guarantors, if any, or the Trustee shall be affected by notice to the contrary.

       Section 3.10  Cancellation.
                     ------------

       All Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly canceled by it. 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 all Securities so delivered shall be
promptly canceled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section,
except as expressly permitted by this Indenture. All canceled Securities held by
the Trustee shall be disposed of as directed by a Company Order or in accordance
with the Trustee's usual practice; provided, however, that the Trustee shall not
be required to destroy canceled Securities.

       Section 3.11  Computation of Interest.
                     -----------------------

       Interest on the Securities shall be computed on the basis of a 360-day
year comprised of twelve 30-day months.

       Section 3.12  Private Placement Legend.
                     ------------------------

          (a) All Transfer Restricted Securities shall bear the Private
Placement Legend upon the original issuance thereof. Upon the transfer, exchange
or replacement of Securities bearing the Private Placement Legend, the Security
Registrar shall deliver only Securities that bear the Private Placement Legend
unless, and the Trustee is hereby authorized to deliver Securities without the
Private Placement Legend if, (i) there is delivered to the Trustee an Opinion of
Counsel to the effect that neither such legend nor the related restrictions on
transfer are required in order to maintain compliance with the provisions of the
Securities Act or (ii) such Security has been sold pursuant to an effective
registration statement under the Securities Act. Upon the transfer, exchange or
replacement of Securities not bearing the Private Placement Legend, the Security
Registrar shall deliver Securities that do not bear the Private Placement
Legend.

                                      -49-
<PAGE>

          (b) Notwithstanding the provisions of the preceding paragraph of this
Section 3.12, the Private Placement Legend on any Transfer Restricted Security
shall be removed upon the request of the Holder thereof upon delivery of such
Security to the Security Registration for exchange at any time after the Resale
Restriction Termination Date.

          (c) By its acceptance of any Security bearing the Private Placement
Legend, each Holder of such a Security acknowledges the restrictions on transfer
of such Security set forth in this Indenture and in the Private Placement Legend
and agrees that it will transfer such Security only as provided in this
Indenture.

Securities, and the Trustee, at the expense of the Company, shall, upon payment
of all amounts due the Trustee under Section 6.6 hereof, execute proper

     theretofore been deposited in trust with the Trustee or any Paying Agent or
     segregated and held in trust by the Company and thereafter repaid to the
     Company or discharged from such trust, as provided in Section 10.3 hereof)

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

     has irrevocably deposited or caused to be deposited with the Trustee funds
     in an amount sufficient to pay and discharge the entire indebtedness on
     such Securities

precedent herein relating to the satisfaction and discharge of this Indenture

all money deposited with the Trustee pursuant to Section 4.1 hereof shall be
held in trust and applied by it, in accordance with the provisions of the
Securities 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
premium, if any) and interest for whose payment such money has been deposited

       Section 5.2  Acceleration of Maturity: Rescission and Annulment.
                    --------------------------------------------------

       If any Event of Default (other than an Event of Default specified in
Section 5.1(h) or (i) hereof) occurs and is continuing, the Trustee or the
Holders of not less than 25% in aggregate principal amount of the Securities
then Outstanding, by written notice to the Company (and to the Trustee if such
notice is given by the Holders), may, and the Trustee upon the request of the
Holders of not less than 25% in aggregate principal amount of the Outstanding
Securities shall, by a notice in writing to the Company, declare all unpaid
principal of, premium, if any, and accrued and unpaid interest on all the
Securities to be due and payable immediately, upon which declaration all amounts
payable in respect of the Securities shall be immediately due and payable. If an
Event of Default specified in Section 5.1(h) or (i) hereof occurs and is
continuing, the amounts described above shall become and be immediately due and
payable without any declaration, notice or other act on the part of the Trustee
or any Holder.

       At any time after a declaration of acceleration 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
aggregate principal amount of the Securities Outstanding, by written notice to
the Company, the Subsidiary Guarantors, if any, and the Trustee, may rescind and
annul such declaration and its consequences if

          (a) the Company or any Subsidiary Guarantor has paid or deposited with
the Trustee a sum sufficient to pay,

          (1) all overdue interest on all Outstanding Securities,

          (2) all unpaid principal of (and premium, if any, on) any Outstanding
     Securities which have become due otherwise than by such declaration of
     acceleration, including any Securities required to have been purchased on a
     Change of Control Purchase Date or a Net Proceeds Payment Date pursuant to
     a Change of Control Offer or a Net Proceeds Offer, as applicable, and
     interest on such unpaid principal at the rate borne by the Securities,

                                      -53-
<PAGE>

          (3) to the extent that payment of such interest is lawful, interest on
     overdue interest and overdue principal at the rate borne by the Securities
     (without duplication of any amount paid or deposited pursuant to clauses
     (1) and (2) above), and

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

          (b) the rescission would not conflict with any judgment or decree of a
court of competent jurisdiction as certified to the Trustee by the Company; and

          (c) all Events of Default, other than the non-payment of amounts of
principal of (or premium, if any, on) or interest on Securities which have
become due solely by such declaration of acceleration, have been cured or waived
as provided in Section 5.13 hereof.

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

       Notwithstanding the foregoing, if an Event of Default specified in
Section 5.1(e) hereof shall have occurred and be continuing, such Event of
Default and any consequential acceleration shall be automatically rescinded if
the Indebtedness that is the subject of such Event of Default has been repaid,
or if the default relating to such Indebtedness is waived or cured and if such
Indebtedness has been accelerated, then the holders thereof have rescinded their
declaration of acceleration in respect of such Indebtedness (provided, in each
case, that such repayment, waiver, cure or rescission is effected within a
period of 10 days from the continuation of such default beyond the applicable
grace period or the occurrence of such acceleration), and written notice of such
repayment, or cure or waiver and rescission, as the case may be, shall have been
given to the Trustee by the Company and countersigned by the holders of such
Indebtedness or a trustee, fiduciary or agent for such holders or other evidence
satisfactory to the Trustee of such events is provided to the Trustee, within 30
days after any such acceleration in respect of the Securities, and so long as
such rescission of any such acceleration of the Securities does not conflict
with any judgment or decree as certified to the Trustee by the Company.

continues for a period of 30 days, or

          (b) default is made in the payment of the principal of (or premium, if
any, on) any Security at the Maturity thereof or with respect to any Security
required to have been purchased by the Company on the Change of Control Purchase
Date or the Net Proceeds Payment Date pursuant to a Change of Control Offer or
Net Proceeds Offer, as applicable, the Company will, upon demand of the Trustee,
pay to the Trustee for the benefit of the Holders of such Securities, the whole
amount then due and payable on such

                                      -54-
<PAGE>

Securities for principal (and premium, if any) and interest, and interest on any
overdue principal (and premium, if any) and, to the extent that payment of such
interest shall be legally enforceable, upon any overdue installment of interest,
at the rate borne by the Securities, 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 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 the Securities and collect the
money adjudged or decreed to be payable in the manner provided by law out of the
Property of the Company or any other obligor upon the Securities, wherever
situated.

       If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders 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.

bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company, any Subsidiary Guarantor or any
other obligor upon the Securities, their creditors or the Property of the
Company, any Subsidiary Guarantor or of such other obligor, the Trustee

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 the
Trustee any amount due to it for the

its agents and counsel, and any other amounts due the Trustee under Section 6.6
hereof.

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 Subsidiary Guarantees, if any, 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.

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

which is absolute and unconditional, to receive payment, as provided herein

                    ----------------------------------

       If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued

       No delay or omission of the Trustee or of any Holder of any Security 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 may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.

the Outstanding Securities 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, provided that

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

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

          (c) the Trustee need not take any action which might involve it in

except a Default or Event of Default,

          (a) in respect of the payment of the principal of (or premium, if any,
on) or interest on any Security, or

          (b) in respect of a covenant or provision hereof which under Article
IX hereof cannot be modified or amended without the consent of the Holder of
each Outstanding Security affected thereby.

       Upon any such waiver, such Default or Event of Default shall cease to
exist for every purpose under this Indenture, but no such waiver shall extend to
any subsequent or other fault or Event of Default or impair any right consequent
thereon. Any such waiver may (but need not) be given in connection with a tender
offer or exchange offer for the Securities.

                     ---------------------------------------

       Each of the Company and the Subsidiary Guarantors, if any, covenants (to
the extent that each may lawfully do so) that it will not at any time insist
upon, plead or in any manner whatsoever claim or take the benefit or advantage
of, any stay, extension, or usury law or other law wherever enacted, now or at
any time hereafter in force, which would prohibit or forgive the Company or any
Subsidiary Guarantor from paying all or any portion of the principal of

which may affect the covenants or the performance of this Indenture; and (to the
extent that it may lawfully do so) each of the Company and the Subsidiary
Guarantors, if any, hereby expressly waives all benefit or advantage of any such
law, and covenant that they 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.

          (a) If an Event of Default has occurred and is continuing, the Trustee
shall exercise the rights and powers vested in it by this Indenture and use the
same degree of care and skill in their exercise as a prudent person would

     truth of the statements and the correctness of the opinions expressed
     therein, upon certificates or opinions furnished to the Trustee and
     conforming to the requirements of this Indenture; provided, however, the
     Trustee shall examine the certificates and opinions to determine whether or
     not they conform to the requirements of this Indenture.

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

              (i)  this paragraph shall not limit the effect of Section 6.1(b);

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

<PAGE>

              (iii) the Trustee shall not be liable with respect to any action
     it takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 5.12.

       Section 6.2  Certain Rights of Trustee.
                    -------------------------

       Subject to the provisions of Section 6.1 hereof:

          (a) the Trustee may conclusively rely and shall be protected in acting
or refraining from acting upon any resolution, certificate, statement,

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;

sufficiently evidenced by a Company Request or Company Order and any resolution
of the Board of Directors may be sufficiently evidenced by a Board Resolution;

          (c) 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;

          (d) 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;

          (e) 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;

          (f) 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 reasonably 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;

          (g) 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;

omitted by it in good faith and believed by it to be authorized or within the
discretion or rights or powers conferred upon it by this Indenture; and

                                      -60-
<PAGE>

          (i) the Trustee shall not be deemed to have notice or knowledge of any
matter unless a Responsible Officer has actual knowledge thereof or unless
written notice thereof is received by the Trustee at its Corporate Trust Office
and such notice references the Securities generally, the Company or this
Indenture.

       The Trustee shall not be required to advance, 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.

       Section 6.3  Trustee Not Responsible for Recitals or Issuance of
                    ---------------------------------------------------
Securities.
----------

       The recitals contained herein and in the Securities and the notations of
Subsidiary Guarantees thereon, if any, except for the Trustee's certificates of
authentication, shall be taken as the statements of the Company or the
Subsidiary Guarantors, as the case may be, and the Trustee assumes no
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture, the Subsidiary Guarantees, if
any, or the Securities, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder.  The Trustee shall not be accountable for
the use or application by the Company of any Securities or the proceeds thereof.

       Section 6.4  May Hold Securities.
                    -------------------

       The Trustee, any Paying Agent, any Security Registrar or any other agent
of the Company, the Subsidiary Guarantors, if any, or of the Trustee, in its
individual or any other capacity, may become the owner or pledgee of Securities
and, subject to TIA Sections 310(b) and 311 in the case of the Trustee, may
otherwise deal with the Company and the Subsidiary Guarantors, if any, with the
same rights it would have if it were not the Trustee, Paying Agent, Security
Registrar or such other agent.

       Section 6.5  Money Held in Trust.
                    -------------------

       Money held by the Trustee in trust hereunder need not be segregated from

liability for interest on any money received by it hereunder except as otherwise
agreed with the Company or any Subsidiary Guarantor.

       Section 6.6  Compensation and Reimbursement.
                    ------------------------------

       The Company agrees:

          (a) 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);

          (b) except as otherwise expressly provided herein, to reimburse the
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

                                      -61-
<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 the Trustee's willful misconduct, negligence or bad faith; and

          (c) to indemnify the Trustee for, and to hold it harmless against, any
loss, liability or expense incurred without willful misconduct, negligence or
bad faith on its part, (i) arising out of or in connection with the acceptance
or administration of this trust, 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 or (ii) in connection with
enforcing this indemnification provision.

       The obligations of the Company under this Section 6.6 to compensate the
Trustee, to pay or reimburse the Trustee for expenses, disbursements and
advances and to indemnify and hold harmless the Trustee shall not be
subordinated to the payment of Senior Indebtedness pursuant to Article XIV
hereof and shall constitute additional indebtedness hereunder and shall survive
the satisfaction and discharge of this Indenture or any other termination under
any Insolvency or Liquidation Proceeding. As security for the performance of
such obligations of the Company, the Trustee shall have a claim and lien prior
to the Securities upon all property and funds held or collected by the Trustee
as such, except funds held in trust for payment of principal of (and premium, if
any, on) or interest on particular Securities. Such lien shall survive the
satisfaction and discharge of this Indenture or any other termination under any
Insolvency or Liquidation Proceeding.

       When the Trustee incurs expenses or renders services after the occurrence
of an Event of Default specified in paragraph (h) or (i) of Section 5.1 of this
Indenture, such expenses and the compensation for such services are intended to
constitute expenses of administration under any Insolvency or Liquidation
Proceeding.

       Section 6.7  Corporate Trustee Required; Eligibility.
                    ---------------------------------------

       There shall at all times be a Trustee hereunder which shall be eligible
to act as Trustee under TIA Section 310(a)(1) and shall have a combined capital
and surplus of at least $50,000,000.  If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of federal,
state, territorial or District of Columbia supervising or examining authority,
then for the purposes of this Section 6.7, 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.

                    ---------------------

operation of TIA Section 310(b)(1) the Existing Indentures and any other
indenture or indentures under which other securities or certificates of interest
or participation in other securities of the Company are outstanding if the
requirements for such exclusion set forth in TIA Section 310(b)(1) are met.

       Section 6.9  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 6.10 hereof.

          (b) The Trustee may resign at any time by giving written notice
thereof to the Company. If the instrument of acceptance by a successor Trustee
required by Section 6.10 hereof 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.

          (c) The Trustee may be removed at any time by Act of the Holders of
not less than a majority in aggregate principal amount of the Outstanding
Securities, delivered to the Trustee and to the Company.

          (d)  If at any time:

          (1) the Trustee shall fail to comply with the provisions of TIA
     Section 310(b) after written request therefor by the Company or by any
     Holder 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 6.7 hereof
     and shall fail to resign after written request therefor by the Company or
     by any Holder who has been a bona fide Holder of a Security for at least
     six months, 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 any 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 such case, (i) the Company, by a Board Resolution, may remove the
Trustee, or (ii) subject to TIA Section 315(e), any Holder 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 and the appointment of a successor Trustee.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee. If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in aggregate principal amount of the Outstanding
Securities delivered to the Company and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment,
become the successor Trustee and supersede the successor Trustee appointed by
the Company. If no successor Trustee shall have been so appointed by the Company
or the Holders and accepted appointment in the manner hereinafter provided, any
Holder 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

                                      -63-
<PAGE>

appointment of a successor Trustee. The evidence of such successorship may, but
need not be, evidenced by a supplemental indenture.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee and each appointment of a successor Trustee to the Holders of
Securities in the manner provided for in Section 15.5 hereof. Each notice shall
include the name of the successor Trustee and the address of its Corporate Trust
Office.

itself) 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:

          (a) hold all sums held by it for the payment of the principal of (and
premium, if any, on) or interest on Securities in trust for the benefit of the
Persons entitled thereto until such sums shall be paid to such Persons or
otherwise disposed of as herein provided;

          (b) give the Trustee notice of any default by the Company (or any
other obligor upon the Securities) in the making of any payment of principal
(and premium, if any) or interest; and

          (c) at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent.

       Initially, the Company shall act as its own Paying Agent, and it shall be
deemed to have agreed with the Trustee that it will adhere to the agreement
described in the immediately preceding paragraph.  Further, the Company shall
give the Trustee notice within 30 days of the making of any payment of principal
(and premium, if any) or interest hereunder by any Paying Agent (including the
Company if acting as its own Paying Agent, but excluding the Trustee), which
notice shall specify the amounts of principal (and premium, if any) and interest
so paid and, in the event of any payment of principal, the aggregate unpaid
principal amount of all Securities then Outstanding.

       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 sums. The Trustee and each Paying Agent shall promptly pay to the Company
upon Company Request any money held by them (other than pursuant to Article XII)
at any time in excess of amounts required to pay principal of, premium, if any,
or interest on the Securities.

       Subject to applicable escheat and abandoned property laws, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium, if any, on) or interest
on any Security and remaining unclaimed for one year after such principal (and
premium, if any) or interest has become due and payable shall be paid to the
Company on Company Request, or (if then held by the Company) shall be discharged
from such trust; and the Holder of such Security shall 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 a newspaper published in the English language, customarily
published on each Business Day and of general circulation in the Borough of
Manhattan, The City of New York, notice that such

                                      -73-

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.

hereof or other provisions of this Indenture, the Company shall do or cause to
be done all things necessary to preserve and keep in full force and effect the
corporate existence, rights (charter and statutory) and franchises of the
Company and each Restricted Subsidiary; provided, however, that the Company
shall not be required to preserve any such existence of its Restricted
Subsidiaries, rights or franchises, if the preservation thereof is no longer
desirable in the conduct of the business of the Company and its Restricted
Subsidiaries, taken as a whole, and that the loss thereof is not disadvantageous
in any material respect to the Holders.

governmental charges levied or imposed upon the Company or any Restricted
Subsidiary or upon the income, profits or Property of the Company or any
Restricted Subsidiary and (b) all lawful claims for labor, materials and
supplies, which, if unpaid, might by law become a Lien upon the Property of the
Company or any Restricted Subsidiary; provided, however, that the Company and
its Restricted Subsidiaries shall not be required to pay or discharge or cause
to be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings and for which appropriate provision has been made in accordance with

       Section 10.6  Maintenance of Properties.
                     -------------------------

Subsidiaries to, cause all material Properties owned by the Company or any
Restricted Subsidiary and used or held for use in the conduct of its business or
the business of any Restricted Subsidiary to be maintained and kept in good
condition, repair and working order (ordinary wear and tear excepted), all as in
the judgment of the Company or such Restricted Subsidiary may be necessary so
that its or its Restricted Subsidiary's business may be properly and
advantageously conducted at all times; provided, however, that nothing in this
Section shall prevent the Company or any Restricted Subsidiary from
discontinuing the maintenance of any of such Properties if such discontinuance
is, in the judgment of the Company or such Restricted Subsidiary, as the case
may be, desirable in the conduct of the business of the Company or such
Restricted Subsidiary and not disadvantageous in any material respect to the
Holders. Notwithstanding the foregoing, nothing contained in this Section 10.6
shall limit or impair in any way the right of the Company and its Restricted
Subsidiaries to sell, divest and otherwise to engage in transactions that are
otherwise permitted by this Indenture.

     exchange for, or out of the aggregate net cash proceeds of, a substantially
     concurrent incurrence (other than to a Restricted Subsidiary) of,
     Subordinated Indebtedness so long as (A) the principal amount of such new

     Indebtedness being refinanced provides for an amount less than the
     principal amount thereof to be due and payable upon a declaration of
     acceleration thereof, such lesser amount as of the date of determination)
     of the Indebtedness being so purchased, redeemed, repaid, defeased,

     employees of the Company or any of its Subsidiaries pursuant to the terms
     of agreements (including employment agreements) or plans approved by the
     Company's Board of Directors, including any such repurchase, redemption,
     acquisition or retirement of such Qualified Capital Stock that is deemed to
     occur upon the exercise of stock options or similar rights if such shares

     Restricted Subsidiaries since June 8, 1998.

The actions described in clause (i) of this paragraph (b) shall be Restricted
Payments that shall be permitted to be taken in accordance with this paragraph
(b) but shall reduce the amount that would otherwise be available for Restricted
Payments under clause (C) of paragraph (a) (provided that any dividend paid
pursuant to clause (i) of this paragraph (b) shall reduce the amount that would
otherwise be available under clause (C) of paragraph (a) when declared, but not
also when subsequently paid pursuant to such clause (i)), and the actions
described in clauses (ii), (iii), (iv), (v) and (vi) of this paragraph (b) shall
be Restricted Payments that shall be permitted to be taken in accordance with
this paragraph (b) and shall not reduce the amount that would otherwise be
available for Restricted Payments under clause (C) of paragraph (a). Further,
the Company or any Restricted Subsidiary may make a Restricted Payment, if at
the time the Company or any Restricted Subsidiary first incurred a commitment
for such Restricted Payment such Restricted Payment could have been made;
provided that all commitments incurred and outstanding shall be treated as if
such commitments were Restricted Payments expended by the Company or a
Restricted Subsidiary at the time the commitments were incurred, except that
commitments incurred and outstanding which are treated as a Restricted Payment
expended by the Company or a Restricted Subsidiary and which are terminated
shall no longer be treated as a Restricted Payment expended by the Company or a
Restricted Subsidiary upon the termination of such commitment for such purposes;
and provided, further, that at the time such Restricted Payment is made no
Default or Event of Default shall have occurred and be continuing and the
Company could incur $1.00 of additional Indebtedness (excluding Permitted
Indebtedness) in accordance with Section 10.12 hereof.

          (c)  In computing Consolidated Net Income of the Company under
paragraph (a) above, (1) the Company shall use audited financial statements for
the portions of the relevant period for which audited financial statements are
available on the date of determination and unaudited financial statements and
other current financial data based on the books and records of the Company for
the remaining portion of such period and (2) the Company shall be permitted to
rely in good faith on the financial statements and other financial data derived
from the books and records of the Company that are available on the date of
determination. If the Company makes a Restricted Payment which, at the time of
the making of such Restricted Payment would in the good faith determination of
the Company be permitted under the requirements of this Indenture, such
Restricted Payment shall be deemed to have been made in compliance with this
Indenture notwithstanding any subsequent adjustments made in good faith to the
Company's financial statements affecting Consolidated Net Income of the Company
for any period.

immediately preceding such event, taken as one period, would have been at least
equal to 2.5 to 1.0.

Subsidiary of any Indebtedness of the Company or one or more Restricted
Subsidiaries shall not be deemed to be outstanding or incurred for purposes of
this Section 10.12 hereof in addition to the amount of Indebtedness which it
guarantees.

to execute and deliver a supplemental indenture to this Indenture, substantially
in the form of Exhibit E hereto, agreeing to be bound by its terms applicable to
a Subsidiary Guarantor and providing for a Subsidiary Guarantee of the

directly or indirectly, create, incur, assume or suffer to exist any Lien of any
kind, except for Permitted Liens, upon any of their respective Properties,
whether now owned or acquired after the date of this Indenture, or any income or
profits therefrom to secure any Pari Passu Indebtedness or Subordinated
Indebtedness, unless prior to or contemporaneously therewith the Securities are
directly secured equally and ratably, provided that (1) if such secured
Indebtedness is Pari Passu Indebtedness, the Lien securing such Pari Passu
Indebtedness shall be subordinate and junior to, or pari passu with, the Lien
securing the Securities and (2) if such secured Indebtedness is Subordinated
Indebtedness, the Lien securing such Subordinated Indebtedness shall be
subordinate and junior to the Lien securing the Securities at least to the same

                      ---------------------------------------------

          (a)  Upon the occurrence of a Change of Control, each Holder of
Securities shall have the right to require the Company to purchase such Holder's
Securities, in whole or in part, in a principal amount that is an integral
multiple of $1,000, pursuant to the offer described in Section 10.16(b) hereof
(the "Change of Control Offer") at a purchase price (the "Change of Control
Purchase Price") in cash equal to 101% of the aggregate principal amount thereof
plus accrued and unpaid interest, if any, thereon to the date of purchase (the
"Change of Control Purchase Date"). The Company will not be required to make a
Change of Control Offer upon a Change of Control if a third party makes the
Change of Control Offer at the same purchase price, at the same times and
otherwise in substantial compliance with the requirements applicable to a Change
of Control Offer made by the Company and purchases all Securities validly
tendered and not withdrawn under such Change of Control Offer.

          (b)  Within 30 calendar days after the date of any Change of Control,
the Company, or the Trustee at the request and expense of the Company, shall
send to each Holder, in the manner provided in Section 15.5, a notice (the
"Change of Control Notice") prepared by the Company describing the transaction
or transactions that constitute the Change of Control and stating:

               (i)    that a Change of Control has occurred and a Change of
     Control Offer is being made pursuant to this Section 10.16, and that all
     Securities that are timely tendered will be accepted for payment;

                                      -81-
<PAGE>

               (ii)   the Change of Control Purchase Price, and the Change of
     Control Purchase Date, which date shall be a Business Day no earlier than
     30 calendar days nor later than 60 calendar days subsequent to the date
     such notice is mailed;

               (iii)  that any Securities or portions thereof not tendered or
     accepted for payment will continue to accrue interest;

               (iv)   that, unless the Company defaults in the payment of the
     Change of Control Purchase Price with respect thereto, all Securities or
     portions thereof accepted for payment pursuant to the Change of Control
     Offer shall cease to accrue interest from and after the Change of Control
     Purchase Date;

               (v)    that any Holder electing to have any Securities or
     portions thereof purchased pursuant to a Change of Control Offer will be
     required to surrender such Securities, with the form to elect purchase by
     the Company pursuant to this Section 10.16 completed, to the Paying Agent
     at the address specified in the notice, prior to the close of business on
     the third Business Day preceding the Change of Control Purchase Date;

               (vi)   that any Holder shall be entitled to withdraw such
     election if the Paying Agent receives, not later than the close of business
     on the second Business Day preceding the Change of Control Purchase Date, a
     facsimile transmission or letter, setting forth the name of the Holder, the
     principal amount of Securities delivered for purchase, and a statement that
     such Holder is withdrawing such Holder's election to have such Securities
     or portions thereof purchased pursuant to the Change of Control Offer;

               (vii)  that any Holder electing to have Securities purchased
     pursuant to the Change of Control offer must specify the principal amount
     that is being tendered for purchase, which principal amount must be $1,000
     or an integral multiple thereof;

               (viii) if Physical Securities have been issued pursuant to
     Section 2.1, that any Holder of Physical Securities whose Physical
     Securities are being purchased only in part will be issued new Physical
     Securities equal in principal amount to the unpurchased portion of the
     Physical Securities surrendered, which unpurchased portion will be equal in
     principal amount to $1,000 or an integral multiple thereof; and

               (ix)   any other information necessary to enable any Holder to
     tender Securities and to have such Securities purchased pursuant to this
     Section 10.16.

If any of the Securities subject to a Change of Control Offer is in the form of
a Global Security, then the Company shall modify the Change of Control Notice to
the extent necessary to accord with the procedures of the Depository applicable
to repurchases.

          (c) On the Change of Control Purchase Date, the Company shall (1)
accept for payment all Securities or portions thereof properly tendered pursuant
to the

                                      -82-
<PAGE>

Change of Control Offer, (2) irrevocably deposit with the Paying Agent, by 11:00
a.m., Eastern time, on such date, in immediately available funds, an amount
equal to the Change of Control Purchase Price in respect of all Securities or
portions thereof so accepted and (3) deliver or cause to be delivered to the
Trustee the Securities so accepted together with an Officers' Certificate
stating the aggregate principal amount of Securities or portions thereof being
purchased by the Company. The Paying Agent shall promptly send, in the manner
provided in Section 15.5, to each Holder of Securities or portions thereof so
accepted for payment the Change of Control Purchase Price for such Securities or
portions thereof. The Company shall publicly announce the results of the Change
of Control Offer on or as soon as practicable after the Change of Control
Purchase Date. For purposes of this Section 10.16, the Trustee shall act as the
Paying Agent.

          (d) Upon surrender and cancellation of a Physical Security that is
purchased in part pursuant to the Change of Control Offer, the Company shall
promptly issue and the Trustee shall authenticate and deliver to the
surrendering Holder of such Physical Security a new Physical Security equal in
principal amount to the unpurchased portion of such surrendered Physical
Security; provided that each such new Physical Security shall be in a principal
amount of $1,000 or an integral multiple thereof.

          (e) The Company shall comply with Rule 14e-1 under the Exchange Act
and any other securities laws and regulations thereunder to the extent such laws
and regulations are applicable, in the event that a Change of Control occurs and
the Company is required to purchase Securities as described in this Section
10.16. To the extent that the provisions of any securities laws or regulations
conflict with the provisions relating to the Change of Control Offer, the
Company will comply with the applicable securities laws and regulations and will
not be deemed to have breached its obligations under this Section 10.16 by
virtue thereof.

          (f) Prior to complying with the provisions of this Section 10.16, but
in any event within 30 days following a Change of Control, the Company shall
either repay all outstanding Senior Indebtedness or obtain the requisite
consents, if any, under all agreements governing outstanding Senior Indebtedness
to permit the repurchase of Securities required by this Section 10.16.

       Section 10.17  Disposition of Proceeds of Asset Sales.
                      --------------------------------------

          (a) The Company shall not, and shall not permit any Restricted
Subsidiary to, engage in any Asset Sale unless (i) the Company or such
Restricted Subsidiary, as the case may be, receives consideration at the time of
such Asset Sale at least equal to the Fair Market Value of the Properties sold
or otherwise disposed of pursuant to the Asset Sale, (ii) all of the
consideration received by the Company or the Restricted Subsidiary, as the case
may be, in respect of such Asset Sale consists of cash, Cash Equivalents, Liquid
Securities or Exchanged Properties ("Permitted Consideration"); provided,
however, that the Company and its Restricted Subsidiaries shall be permitted to
receive any Property other than Permitted Consideration, so long as the
aggregate Fair Market Value (determined on the date of each Asset Sale) of such
Property other than Permitted Consideration received from Asset Sales and held
by the Company or any Restricted Subsidiary at any one time shall not exceed
10.0% of Adjusted Consolidated Net Tangible Assets and (iii) the Company
delivers to the Trustee an Officers' Certificate (which Officers' Certificate
shall be conclusive) certifying that such Asset Sale complies with clauses (i)
and (ii) of this Section 10.17(a). The amount (without duplication) of any

                                      -83-
<PAGE>

Indebtedness (other than Subordinated Indebtedness or Pari Passu Indebtedness)
of the Company or such Restricted Subsidiary that is expressly assumed by the
transferee in such Asset Sale and with respect to which the Company or such
Restricted Subsidiary, as the case may be, is unconditionally released by the
holder of such Indebtedness, shall be deemed to be cash or Cash Equivalents for
purposes of clause (ii) and shall also be deemed to constitute a repayment of,
and a permanent reduction in, the amount of such Indebtedness for purposes of
the next following paragraph.

          (b) If the Company or any Restricted Subsidiary engages in an Asset
Sale after the date of this Indenture, the Company or such Restricted Subsidiary
may either, no later than 365 days after such Asset Sale, (i) apply all or any
of the Net Cash Proceeds therefrom to (A) repay Indebtedness under the Credit
Facility or (B) repay or purchase other Indebtedness (other than Subordinated
Indebtedness or Pari Passu Indebtedness) of the Company or any Restricted
Subsidiary, provided, in the case of clause (B), that the related loan
commitment (if any) is thereby permanently reduced by the amount of such
Indebtedness so repaid or purchased, or (ii) invest all or any part of the Net
Cash Proceeds thereof in Properties that will be used in the Oil and Gas
Business of the Company or its Restricted Subsidiaries, as the case may be. The
amount of such Net Cash Proceeds not applied or invested as provided in this
paragraph (after the periods specified in this paragraph) shall constitute
"Excess Proceeds."

          (c) When the aggregate amount of Excess Proceeds equals or exceeds
$10,000,000 (the "Trigger Date"), the Company shall make an offer to purchase,
from all Holders of the Securities and holders of any then outstanding Pari
Passu Indebtedness required to be repurchased or repaid on a permanent basis in
connection with an Asset Sale, an aggregate principal amount of Securities and
any such Pari Passu Indebtedness equal to such Excess Proceeds as follows:

          (1) Not later than the 30th day following the Trigger Date, the
     Company shall (i) give to the Trustee in the manner provided in Section
     15.4 hereof and each Holder of the Securities in the manner provided in
     Section 15.5 hereof, a notice (a "Purchase Notice") offering to purchase (a
     "Net Proceeds Offer") from all Holders of the Securities the maximum
     principal amount (expressed as a multiple of $1,000) of Securities that may
     be purchased out of an amount (the "Payment Amount") equal to the product
     of such Excess Proceeds multiplied by a fraction, the numerator of which is
     the outstanding principal amount of the Securities and the denominator of
     which is the sum of the outstanding principal amount of the Securities and
     any such Pari Passu Indebtedness (subject to proration in the event such
     amount is less than the aggregate Offered Price (as hereinafter defined) of
     all Securities tendered), and (ii) to the extent required by any Pari Passu
     Indebtedness and provided there is a permanent reduction in the principal
     amount of such Pari Passu Indebtedness, the Company shall make an offer to
     purchase such Pari Passu Indebtedness (a "Pari Passu Offer") in an amount
     (the "Pari Passu Indebtedness Amount") equal to the excess of the Excess
     Proceeds over the Payment Amount.

          (2) The offer price for the Securities shall be payable in cash in an
     amount equal to 100% of the aggregate principal amount of the Securities
     tendered pursuant to a Net Proceeds Offer, plus accrued and unpaid
     interest, if any, to the date such Net Proceeds Offer is consummated (the
     "Offered Price"), in accordance with paragraph (d) of this Section. To the
     extent that the aggregate Offered Price of the Securities tendered pursuant
     to a Net Proceeds Offer is less than the Payment

                                      -84-
<PAGE>

     Amount relating thereto or the aggregate amount of the Pari Passu
     Indebtedness that is purchased or repaid pursuant to the Pari Passu Offer
     is less than the Pari Passu Indebtedness Amount (such shortfall
     constituting a "Net Proceeds Deficiency"), the Company may use such Net
     Proceeds Deficiency, or a portion thereof, for general corporate purposes,
     subject to the limitations of Section 10.10 hereof.

          (3) If the aggregate Offered Price of Securities validly tendered and
     not withdrawn by Holders thereof exceeds the Payment Amount, Securities to
     be purchased will be selected on a pro rata basis by the Trustee based on
     the aggregate principal amount of Securities so tendered. Upon completion
     of a Net Proceeds Offer and a Pari Passu Offer, the amount of Excess
     Proceeds shall be reset to zero.

          (4) The Purchase Notice shall set forth a purchase date (the "Net
     Proceeds Payment Date"), which shall be on a Business Day no earlier than
     30 days nor later than 60 days from the Trigger Date. The Purchase Notice
     shall also state (i) that a Trigger Date with respect to one or more Asset
     Sales has occurred and that such Holder has the right to require the
     Company to repurchase such Holder's Securities at the Offered Price,
     subject to the limitations described in the forgoing paragraph (3), (ii)
     any information regarding such Net Proceeds Offer required to be furnished
     pursuant to Rule 14e-1 under the Exchange Act and any other securities laws
     and regulations thereunder, (iii) that any Security, or portion thereof,
     not tendered or accepted for payment will continue to accrue interest, (iv)
     that, unless the Company defaults in depositing money with the Paying Agent
     in accordance with the last paragraph of clause (d) of this Section 10.17,
     or payment is otherwise prevented, any Security, or portion thereof,
     accepted for payment pursuant to the Net Proceeds Offer shall cease to
     accrue interest after the Net Proceeds Payment Date, and (v) the
     instructions a Holder must follow in order to have his Securities
     repurchased in accordance with paragraph (d) of this Section.

          (d) Holders electing to have Securities purchased will be required to
surrender such Securities to the Paying Agent at the address specified in the
Purchase Notice prior to the close of business on the third Business Days prior
to the Net Proceeds Payment Date. Holders will be entitled to withdraw their
election if the Paying Agent receives, not later than the close of business on
the second Business Days prior to the Net Proceeds Payment Date, a facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Securities delivered for purchase by the Holder as to which his
election is to be withdrawn and a statement that such Holder is withdrawing his
election to have such Securities purchased. Holders of Physical Securities whose
Securities are purchased only in part will be issued new Securities equal in
principal amount to the unpurchased portion of the Securities surrendered, which
unpurchased portion will be equal to $1,000 or an integral multiple thereof.

       On the Net Proceeds Payment Date, the Company shall (i) accept for
payment Securities or portions thereof validly tendered pursuant to a Net
Proceeds Offer in an aggregate principal amount equal to the Payment Amount or
such lesser amount of Securities as has been tendered, (ii) irrevocably deposit
with the Paying Agent, by 11:00 a.m., Eastern time, immediately available funds
sufficient to pay the purchase price of all Securities or portions thereof so
tendered in an aggregate principal amount equal to the Payment Amount or such
lesser amount and (iii) deliver or cause to be delivered to the Trustee the
Securities so accepted. The Paying Agent shall promptly send, in the manner

                                      -85-
<PAGE>

provided in Section 15.5, to Holders of the Securities so accepted payment in an
amount equal to the purchase price, and the Company shall execute and the
Trustee shall authenticate and mail or make available for delivery to such
Holders a new Security equal in principal amount to any unpurchased portion of
the Security which any such Holder did not surrender for purchase. Any
Securities not so accepted will be promptly mailed or delivered to the Holder
thereof. The Company shall announce the results of a Net Proceeds Offer on or as
soon as practicable after the Net Proceeds Payment Date. For purposes of this
Section 10.17, the Trustee will act as the Paying Agent.

          (e) The Company shall not permit any Restricted Subsidiary to enter
into or suffer to exist any agreement that would place any restriction of any
kind (other than pursuant to law or regulation) on the ability of the Company to
make a Net Proceeds Offer following any Asset Sale. The Company shall comply
with Rule 14e-1 under the Exchange Act and any other securities laws and
regulations thereunder, if applicable, in the event that an Asset Sale occurs
and the Company is required to purchase Securities as described in this Section
10.17. To the extent that the provisions of any securities laws or regulations
conflict with the provisions relating to the Net Proceeds Offer, the Company
will comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under this Section 10.17 by virtue
thereof.

Affiliate of the Company (other than the Company or a Restricted Subsidiary)
unless (i) such transaction or series of related transactions is on terms that
are no less favorable to the Company or such Restricted Subsidiary, as the case
may be, than would be available in a comparable transaction in arm's-length
dealings with an unrelated third party, (ii) with respect to a transaction or
series of related transactions involving payments in excess of $1,000,000 in the
aggregate, the Company delivers an Officers' Certificate to the Trustee

the Disinterested Directors of the Company, (t) loans or advances to officers,
directors and employees of the

Holders of at least a majority in aggregate principal amount of the Outstanding
Securities, by Act of such Holders, waive such compliance in such instance with

       The Company shall qualify this Indenture under the TIA in accordance with

                                  ARTICLE XI

                           REDEMPTION OF SECURITIES

       Section 11.1  Right of Redemption.
                     -------------------

       The Securities may be redeemed, at the election of the Company, as a
whole or from time to time in part, at any time on or after October 1, 2005,
upon not less than 30 or more than 60 days' notice to each Holder of Securities
to be redeemed, subject to the conditions and at the Redemption Prices
(expressed as percentages of principal amount) specified in the form of
Security, together with accrued and unpaid interest, if any, to the Redemption
Date.

       Notwithstanding the foregoing, prior to October 1, 2003 the Company may,
at any time or from time to time, redeem up to 33 1/3% of the aggregate
principal amount of the Securities originally issued (excluding, for this
purpose, any Securities issued in exchange for Series A Securities) at a
Redemption Price of 109.375% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the Redemption Date, with the net proceeds of one or
more Equity Offerings of the Company, provided that at least 66 2/3% of the
aggregate principal amount of the Securities originally issued at any time prior
to such redemption (excluding, for this purpose, any Series B Securities issued
in exchange for Series A Securities) remains Outstanding after the occurrence of
such redemption and provided, further, that such redemption shall occur not
later than 90 days after the date of the closing of any such Equity Offering.

       Section 11.2  Applicability of Article.
                     ------------------------

       Redemption of Securities at the election of the Company or otherwise, as
permitted or required by any provision of this Indenture, shall be made in
accordance with such provision and this Article.

       Section 11.3  Election to Redeem; Notice to Trustee.
                     -------------------------------------

       The election of the Company to redeem any Securities pursuant to Section
11.1 hereof shall be evidenced by a Board Resolution. In case of any redemption
at the election of the Company, the Company shall, at least 60 days (or, in the
case of a full redemption of all Outstanding Securities, 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 and of
the principal amount of Securities to be redeemed and shall deliver to the
Trustee such documentation and records as shall enable the Trustee to select the
Securities to be redeemed pursuant to Section 11.4 hereof. Any election to
redeem

                                      -88-
<PAGE>

Securities shall be revocable until the Company gives a notice of redemption
pursuant to Section 11.5 hereof to the Holders of Securities to be redeemed.

       Section 11.4  Selection by Trustee of Securities to Be Redeemed.
                     -------------------------------------------------

       If less than all the Securities are to be redeemed, the particular
Securities to be redeemed shall be selected not less than 30 days nor more than
60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities not previously called for redemption, pro rata or by any other method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions of the principal of Securities; provided,
however, that any such partial redemption shall be in integral multiples of
$1,000.

       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.

       The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a Global Security, whether such Global
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the Global
Security shall be in an authorized denomination.

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

       Section 11.5  Notice of Redemption.
                     --------------------

       Notice of redemption shall be given in the manner provided for in Section
15.5 hereof not less than 30 nor more than 60 days prior to the Redemption Date,
to each Holder of Securities to be redeemed.

       All notices of redemption shall state:

          (a)  the Redemption Date;

          (b)  the Redemption Price;

          (c) in the case of a partial redemption of Physical Securities, the

accrued interest, if any, to the Redemption Date payable as provided in Section
11.7 hereof) will become due and payable upon each such Security, or the portion
thereof, to be redeemed, and that, unless the Company shall default in the
payment of the Redemption Price and any applicable accrued and unpaid interest,
interest thereon will cease to accrue on and after said date; and

          (e) the place or places where such Securities are to be surrendered
for payment of the Redemption Price.

       If any Security to be redeemed is in global form, then the Company shall
modify such notice to the extent necessary to accord with the procedures of the
Depository applicable to repurchases.

       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

                     ---------------------------

       On or before 11:00 a.m., Eastern time, on 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 10.3 hereof) immediately available funds in an amount
sufficient to pay the Redemption Price of, and any accrued and unpaid interest
on, all the Securities which are to be redeemed on such 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 (together with accrued and unpaid interest,
if any, to the Redemption Date), and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued and
unpaid interest) such Securities shall cease to bear interest. Upon surrender of
any such Security for redemption in accordance with said notice, such Security
shall be paid by the Company at the Redemption Price, together with accrued and
unpaid interest, if any, to the Redemption Date; provided, however, that
installments of interest 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 3.8
hereof.

       If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate borne by the Securities.

       Section 11.8  Securities Redeemed in Part.

pursuant to Section 10.2 hereof (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, the Holder thereof
or such Holder's 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 Physical Security or Securities, of like
tenor

       Section 12.1  Company's Option to Effect Defeasance or Covenant
                     -------------------------------------------------
Defeasance.
----------

       The Company may, at its option by Board Resolution, at any time, with
respect to the Securities, elect to have either Section 12.2 or Section 12.3
hereof be applied to all Outstanding Securities upon compliance with the
conditions set forth below in this Article XII.

       Section 12.2  Defeasance and Discharge.
                     ------------------------

       Upon the Company's exercise under Section 12.1 hereof of the option
applicable to this Section 12.2, the Company and the Subsidiary Guarantors, if
any, shall be deemed to have been discharged from their respective obligations
with respect to all Outstanding Securities on the date the conditions set forth
in Section 12.4 hereof are satisfied (hereinafter, "legal defeasance"). For this
purpose, such legal defeasance means that the Company and the Subsidiary
Guarantors, if any, shall be deemed (i) to have paid and discharged their
respective obligations under the Outstanding Securities; provided, however, that
the Securities shall continue to be deemed to be "Outstanding" for purposes of
Section 12.5 hereof and the other Sections of this Indenture referred to in
clauses (A) and (B) below, and (ii) to have satisfied all their other
obligations with respect to such Securities and this Indenture (and the Trustee,
at the expense and direction 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
Outstanding Securities to receive, solely from the trust fund described in
Section 12.4 hereof and as more fully set forth in such Section, payments in
respect of the principal of (and premium if any, on) and interest on such
Securities when such payments are due (or at such time as the Securities would
be subject to redemption at the option of the Company in accordance with this
Indenture), (B) the respective obligations of the Company and the Subsidiary
Guarantors, if any, under Sections 3.3, 3.4, 3.5, 3.6, 3.7, 5.8, 6.6, 6.9, 6.10,
10.2, 10.3, 10.21, 13.1 (to the extent it relates to the foregoing Sections and
this Article XII), 13.4 and 13.5 hereof, (C) the rights, powers, trusts, duties
and immunities of the Trustee hereunder, and (D) the obligations of the Company
and the Subsidiary Guarantors, if any, under this Article XII. Subject to
compliance with this Article XII, the Company may exercise its option under this
Section 12.2 notwithstanding the prior exercise of its option under Section 12.3
hereof with respect to the Securities.

       Section 12.3  Covenant Defeasance.
                     -------------------

       Upon the Company's exercise under Section 12.1 hereof of the option
applicable to this Section 12.3, (i) the Company and each Subsidiary Guarantor,
if any, shall be released from their respective obligations under any covenant
contained in Article VIII, in Sections 10.5 through 10.19 and in Section 13.2
hereof, and any covenant added to this Indenture pursuant to Section 9.1(b), and
(ii) the occurrence of any event specified in Section 5.1(c) or 5.1(d) hereof
(with respect to any of Article VIII, Sections 10.5 through 10.19, Section 13.2
and any covenant added to this Indenture pursuant to Section 9.1(b)) shall be
deemed not to be or result in an Event of Default, in each case with respect to
the Outstanding Securities on and after the date the conditions set forth below
are satisfied (hereinafter, "covenant defeasance"), and the Securities shall
thereafter be deemed not to be "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"Outstanding" for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to the Outstanding Securities, the Company
and each Subsidiary Guarantor, if any, may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
Article or Section (to the extent so specified in the case of Sections 5.1(c)
and 5.1(d) hereof), whether directly or indirectly, by reason of any reference
elsewhere herein to any such Article or Section or by reason of any reference in
any such Article or Section to any other provision herein or in any other
document, but, except as specified above, the remainder of this Indenture and
such Securities shall be unaffected thereby. In addition, upon the Company's
exercise under Section 12.1 hereof of the option applicable to this Section
12.3, subject to the satisfaction of the conditions set forth in Section 12.4
hereof, Sections 5.1(e) and 5.1(g) hereof shall thereafter not constitute Events
of Default.

       Section 12.4  Conditions to Defeasance or Covenant Defeasance.
                     -----------------------------------------------

       The following shall be the conditions to application of either Section
12.2 or Section 12.3 hereof to the Outstanding Securities:

          (a) The Company or any Subsidiary Guarantor shall irrevocably have
deposited or caused to be deposited with the Trustee (or another trustee
satisfying the requirements of Section 6.7 hereof who shall agree to comply with
the provisions of this Article XII 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 such Securities, (A)
cash in U.S. Dollars 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, on) and interest on the Outstanding Securities on the Stated Maturity
thereof (or Redemption Date, if applicable), provided that the Trustee shall
have been irrevocably instructed in writing by the Company to apply such money
or the proceeds of such U.S. Government Obligations to said payments with
respect to the Securities. Before such a deposit, the Company may give to the
Trustee, in accordance with Section 11.3 hereof, a notice of its election to
redeem all of the Outstanding Securities at a future date in accordance with
Article XI hereof, which notice shall be

                                      -92-
<PAGE>

irrevocable. Such irrevocable redemption notice, if given, shall be given effect
in applying the foregoing. For this purpose, "U.S. Government Obligations" means
securities that are (x) direct obligations of the United States of America for
the timely 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 of America the timely payment of which is
unconditionally guaranteed as a full faith and credit obligation by the United
States of America, 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), 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.

          (b) No Default or Event of Default with respect to the Securities
shall have occurred and be continuing on the date of such deposit or, insofar as
Sections 5.1(h) and 5.1(i) are concerned, at any time during the period ending
on the 91st day after the date of such deposit.

          (c) Such legal defeasance or covenant defeasance shall not cause the
Trustee to have a conflicting interest under this Indenture or the Trust
Indenture Act with respect to any securities of the Company or any Subsidiary
Guarantor.

          (d) Such legal defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a default under any other material
agreement or instrument to which the Company or any Subsidiary Guarantor is a
party or by which it is bound, as evidenced to the Trustee in an Officers'
Certificate delivered to the Trustee concurrently with such deposit.

          (e) In the case of an election under Section 12.2 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel stating that (i) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since the date of this Indenture there has been a
change in the applicable federal income tax laws, in either case providing that
the Holders of the Outstanding Securities will not recognize income, gain or
loss for federal income tax purposes as a result of such legal defeasance and
will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such legal defeasance had
not occurred (it being understood that (x) such Opinion of Counsel shall also
state that such ruling or applicable law is consistent with the conclusions
reached in such Opinion of Counsel and (y) the Trustee shall be under no
obligation to investigate the basis or correctness of such ruling).

          (f) In the case of an election under Section 12.3 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of the Outstanding Securities will not recognize income, gain or loss
for federal income tax purposes as a result of such covenant defeasance and will
be subject to federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if such covenant defeasance had not
occurred.

                                      -93-
<PAGE>

          (g) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, which, taken together, state that all
conditions precedent provided for relating to either the legal defeasance under
Section 12.2 hereof or the covenant defeasance under Section 12.3 (as the case
may be) have been complied with.

       Section 12.5  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 10.3 hereof,
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 12.5, the "Trustee") pursuant to Section 12.4 hereof in
respect of the Outstanding Securities shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities 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 such Securities 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. Governmental Obligations
deposited pursuant to Section 12.4 hereof or the principal and interest received
in respect thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of the Outstanding Securities.

       Anything in this Article XII 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 12.4
hereof 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 legal defeasance or covenant defeasance, as
applicable, in accordance with this Article.

       Section 12.6  Reinstatement.
                     -------------

       If the Trustee or any Paying Agent is unable to apply any money in
accordance with Section 12.5 hereof by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company's and any Subsidiary Guarantors' obligations
under this Indenture and the Securities shall be revived and reinstated as
though no deposit had occurred pursuant to Section 12.2 or 12.3 hereof, as the
case may be, until such time as the Trustee or Paying Agent is permitted to
apply all such money in accordance with Section 12.5 hereof; provided, however,
that if the Company or any Subsidiary Guarantor makes any payment of principal
of (or premium, if any, on) or interest on any Security following the
reinstatement of its obligations, the Company or such Subsidiary Guarantor shall
be subrogated to the rights of the Holders of such Securities to receive such
payment from the money held by the Trustee or Paying Agent.

                             SUBSIDIARY GUARANTEES

       Section 13.1  Unconditional Guarantee.
                     -----------------------

       Each Subsidiary Guarantor, if any, hereby unconditionally, jointly and
severally, guarantees (each such guarantee being referred to herein as this
"Subsidiary Guarantee," with all such guarantees being referred to herein as the
"Subsidiary Guarantees") to each Holder of Securities authenticated and
delivered by the Trustee and to the Trustee and its successors and assigns, the
full and prompt performance of the Company's obligations under this Indenture
and the Securities and that:

          (a) the principal of (and premium, if any, on) and interest on the
Securities will be promptly paid in full when due (subject to any applicable
grace periods), whether at maturity, by acceleration, redemption or otherwise,
and interest on the overdue principal of and interest on the Securities, if any,
to the extent lawful, and all other obligations of the Company to the Holders or
the Trustee hereunder or thereunder will be promptly paid in full or performed,
all in accordance with the terms hereof and thereof; and

          (b) in case of any extension of time of payment or renewal of any
Securities or of any such other obligations, the same will be promptly paid in
full when due or performed in accordance with the terms of the extension or
renewal, whether at Stated Maturity by acceleration or otherwise;

       subject, however, in the case of clauses (a) and (b) above, to the
limitations set forth in Section 13.4 hereof.

       Failing payment when due of any amount so guaranteed or any performance
so guaranteed for whatever reason, the Subsidiary Guarantors will be jointly and
severally obligated to pay the same immediately. Each Subsidiary Guarantor
hereby agrees that its obligations hereunder shall, to the extent permitted by
law, be unconditional, irrespective of the validity, regularity or
enforceability of the Securities or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Securities with
respect to any provisions hereof or thereof, the recovery of any judgment
against the Company, any action to enforce the same or any other circumstance
which might otherwise constitute a legal or equitable discharge or defense of a
guarantor.  Each Subsidiary Guarantor hereby waives, to the extent permitted by
law, diligence, presentment, demand of payment, filing of claims with a court in
the event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and covenants that its Subsidiary Guarantee will not be discharged except by
complete performance of the obligations contained in the Securities, this
Indenture and in this Subsidiary Guarantee. If any Holder or the Trustee is
required by any court or otherwise to return to the Company, any Subsidiary
Guarantor, or any custodian, trustee, liquidator or other similar official
acting in relation to the Company or any Subsidiary Guarantor, any amount paid
by the Company or any Subsidiary Guarantor to the Trustee or such Holder, this
Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated
in full force and effect.  Each Subsidiary Guarantor agrees it shall not be
entitled to enforce any right of subrogation in relation to the Holders in
respect of any obligations guaranteed hereby until payment in full of all
obligations

                                      -95-
<PAGE>

guaranteed hereby. Each Subsidiary Guarantor further agrees that, as between
each Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on
the other hand, (x) the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article V hereof for the purposes of this Subsidiary
Guarantee, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the obligations guaranteed hereby, and (y) in
the event of any acceleration of such obligations as provided in Article V
hereof, such obligations (whether or not due and payable) shall forthwith become
due and payable by each Subsidiary Guarantor for the purpose of this Subsidiary
Guarantee.

       Section 13.2   Subsidiary Guarantors May Consolidate, etc., on Certain
                      -------------------------------------------------------
Terms.
-----

          (a) Except as set forth in Article VIII hereof, nothing contained in
this Indenture or in any of the Securities shall prevent any consolidation or
merger of a Subsidiary Guarantor with or into the Company or another Subsidiary
Guarantor or shall prevent any sale, conveyance or other disposition of all or
substantially all the Properties of a Subsidiary Guarantor to the Company or
another Subsidiary Guarantor.

          (b) Except as set forth in Article VIII hereof, nothing contained in
this Indenture or in any of the Securities shall prevent any consolidation or
merger of a Subsidiary Guarantor with or into a Person other than the Company or
another Subsidiary Guarantor (whether or not Affiliated with the Subsidiary
Guarantor), or successive consolidations or mergers in which a Subsidiary
Guarantor or its successor or successors shall be a party or parties, or shall
prevent any sale, conveyance or other disposition of all or substantially all
the Properties of a Subsidiary Guarantor to a Person other than the Company or
another Subsidiary Guarantor (whether or not Affiliated with the Subsidiary
Guarantor) authorized to acquire and operate the same; provided, however, that
(i) immediately after such transaction, and giving effect thereto, no Default or
Event of Default shall have occurred as a result of such transaction and be
continuing, (ii) such transaction shall not violate any of the covenants of
Sections 10.1 through 10.19 hereof, and (iii) each Subsidiary Guarantor hereby
covenants and agrees that, upon any such consolidation, merger, sale, conveyance
or other disposition, such Subsidiary Guarantor's Subsidiary Guarantee set forth
in this Article XIII and in a notation to the Securities, and the due and
punctual performance and observance of all of the covenants and conditions of
this Indenture to be performed by such Subsidiary Guarantor, shall be expressly
assumed (in the event that the Subsidiary Guarantor is not the surviving
corporation in a merger), by supplemental indenture substantially in the form of
Exhibit E hereto, executed and delivered to the Trustee, by such Person formed
by such consolidation, or into which the Subsidiary Guarantor shall have merged,
or by the Person that shall have acquired such Property (except to the extent
the following Section 13.3 would result in the release of such Subsidiary
Guarantee, in which case such surviving Person or transferee of such Property
shall not have to execute any such supplemental indenture and shall not have to
assume such Subsidiary Guarantor's Subsidiary Guarantee). In the case of any
such consolidation, merger, sale, conveyance or other disposition and upon the
assumption by the successor Person, by supplemental indenture executed and
delivered to the Trustee substantially in the form of Exhibit E hereto of the
due and punctual performance of all of the covenants and conditions of this
Indenture to be performed by the Subsidiary Guarantor, such successor Person
shall succeed to and be substituted for the Subsidiary Guarantor with the same
effect as if it had been named herein as the initial Subsidiary Guarantor.

       Section 13.3  Release of Subsidiary Guarantors.
                     --------------------------------

       Upon the sale or disposition (by merger or otherwise) of a Subsidiary
Guarantor (or all or substantially all of its Properties) to a Person other than
the Company or another Subsidiary Guarantor and pursuant to a transaction that
is otherwise in compliance with the terms of this Indenture, including but not
limited to the provisions of Section 13.2 hereof or pursuant to Article VIII
hereof, such Subsidiary Guarantor shall be deemed released from its Subsidiary
Guarantee and all related obligations under this Indenture; provided, however,
that any such termination shall occur only to the extent that all obligations of
such Subsidiary Guarantor under all of its guarantees of, and under all of its
pledges of assets or other security interests which secure, other Indebtedness
of the Company or any other Restricted Subsidiary shall also terminate upon such
sale or other disposition.  The Trustee shall deliver an appropriate instrument
evidencing such release upon receipt of a Company Request accompanied by an
Officers' Certificate and an Opinion of Counsel certifying that such sale or
other disposition was made by the Company in accordance with the provisions of
this Indenture.

       Each Subsidiary Guarantor that is designated as an Unrestricted
Subsidiary in accordance with the provisions of this Indenture shall be released
from its Subsidiary Guarantee and all related obligations under this Indenture
for so long as it remains an Unrestricted Subsidiary. The Trustee shall deliver
an appropriate instrument evidencing such release upon its receipt of the Board
Resolution designating such Unrestricted Subsidiary.

       Notwithstanding any other provision of this Indenture, all of the
Subsidiary Guarantors shall be deemed released from their respective Subsidiary
Guarantees and all related obligations under this Indenture in the event that
all obligations of the Subsidiary Guarantors under all of their guarantees of,
and under all of their pledges of assets or other security interests which
secure, other Indebtedness of the Company (excluding any Senior Indebtedness)
shall also terminate. The Trustee shall deliver an appropriate instrument
evidencing such release upon receipt of a Company Request accompanied by an
Officer's Certificate and Opinion of Counsel certifying that all such
obligations of the Subsidiary Guarantors have terminated.

       Any Subsidiary Guarantor not released in accordance with this Section
13.3 shall remain liable for the full amount of principal of (and premium, if
any, on) and interest on the Securities as provided in this Article XIII.

       Section 13.4  Limitation of Subsidiary Guarantors' Liability.
                     ----------------------------------------------

       Each Subsidiary Guarantor, and by its acceptance hereof each Holder,
hereby confirm that it is the intention of all such parties that the guarantee
by such Subsidiary Guarantor pursuant to its Subsidiary Guarantee not constitute
a fraudulent transfer or conveyance for purposes of the Federal Bankruptcy Code,
the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or
any similar federal or state law. To effectuate the foregoing intention, the
Holders and each Subsidiary Guarantor hereby irrevocably agree that the
obligations of such Subsidiary Guarantor under its Subsidiary Guarantee shall be
limited to the maximum amount as will, after giving effect to all other
contingent and fixed liabilities (including, but not limited to, Guarantor
Senior Indebtedness) of such Subsidiary Guarantor and after giving effect to any
collections from or payments made by or on behalf of any other Subsidiary
Guarantor in respect of the

                                      -97-
<PAGE>

obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or
pursuant to Section 13.5 hereof, result in the obligations of such Subsidiary
Guarantor under its Subsidiary Guarantee not constituting such a fraudulent
conveyance or fraudulent transfer. This Section 13.4 is for the benefit of the
creditors of each Subsidiary Guarantor, and, for purposes of the Federal
Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent
Transfer Act any each other similar federal or state law, any Indebtedness of a
Subsidiary Guarantor incurred from time to time pursuant to the Credit Facility

Guarantor of liability under its Subsidiary Guarantee.

       Section 13.5  Contribution.
                     ------------

       In order to provide for just and equitable contribution among the
Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the
event any payment or distribution is made by any Subsidiary Guarantor (a
"Funding Guarantor") under its Subsidiary Guarantee, such Funding Guarantor
shall be entitled to a contribution from each other Subsidiary Guarantor (if
any) in a pro rata amount based on the Adjusted Net Assets of each Subsidiary
Guarantor (including the Funding Guarantor) for all payments, damages and
expenses incurred by that Funding Guarantor in discharging the Company's
obligations with respect to the Securities or any other Subsidiary Guarantor's
obligations with respect to its Subsidiary Guarantee.

       Section 13.6  Execution and Delivery of Notations of Subsidiary
                     -------------------------------------------------
                     Guarantees.
                     ----------

       To evidence its Subsidiary Guarantee set forth in Section 13.1 hereof,
each Subsidiary Guarantor hereby agrees to execute the notations of Subsidiary
Guarantees in substantially the form set forth in Section 2.4 hereof to be
endorsed on all Securities ordered to be authenticated and delivered by the
Trustee, unless at such time there are no Subsidiary Guarantors, and each
Subsidiary Guarantor agrees that any supplement to this Indenture shall be
executed on behalf of such Subsidiary Guarantor by its President or one of its
Vice Presidents.  Each Subsidiary Guarantor hereby agrees that its Subsidiary
Guarantee set forth in Section 13.1 hereof shall remain in full force and effect
notwithstanding any failure to endorse on each Security a notation of such
Subsidiary Guarantee. Each such notation of Subsidiary Guarantee shall be signed
on behalf of each Subsidiary Guarantor by its President or one of its Vice
Presidents (each of whom shall, in each case, have been duly authorized by all
requisite corporate action) prior to the authentication of the Security on which
it is endorsed, and the delivery of such Security by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of the
Subsidiary Guarantee set forth in this Indenture on behalf of such Subsidiary
Guarantor. Such signatures upon the notation of Subsidiary Guarantee may be by
manual or facsimile signature of such officers and may be imprinted or otherwise
reproduced on the Subsidiary Guarantee, and in case any such officer who shall
have signed the notation of Subsidiary Guarantee shall cease to be such officer
before the Security on which such notation of Subsidiary Guarantee is endorsed
shall have been authenticated and delivered by the Trustee or disposed of by the
Company, such Security nevertheless may be authenticated and delivered or
disposed of as though the person who signed the notation of Subsidiary Guarantee
had not ceased to be such officer of the Subsidiary Guarantor.

       Section 13.7  Severability.
                     ------------

       In case any provision of this Subsidiary Guarantee shall be invalid,
illegal or unenforceable, that portion of such provision that is not invalid,
illegal or unenforceable shall remain in effect, and the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

                     -------------------------------------------------------
                     Indebtedness.
                     ------------

       Each Subsidiary Guarantor covenants and agrees, and each Holder of a
Security, by his acceptance of the Subsidiary Guarantees, likewise covenants and
agrees, for the benefit of the holders, from time to time, of Guarantor Senior
Indebtedness, that the indebtedness, obligations and liabilities of such
Subsidiary Guarantor in respect of its Subsidiary Guarantee are subordinated and
subject in right of payment, to the extent and in the manner provided in this
Article XIII, to the prior payment in full of all Guarantor Senior Indebtedness
of such Subsidiary Guarantor, whether outstanding on the date of this Indenture
or thereafter created, incurred, assumed or guaranteed; provided, however, that
the Subsidiary Guarantee of such Subsidiary Guarantor, the Indebtedness
represented thereby and the payment of the principal of (and premium, if any,
on) and the interest on the Securities pursuant to such Subsidiary Guarantee in
all respects shall rank pari passu with, or prior to, all existing and future
unsecured indebtedness (including, without limitation, Indebtedness) of such
Subsidiary Guarantor that is subordinated to its Guarantor Senior Indebtedness.

       This Article XIII shall constitute a continuing offer to all Persons who,
in reliance upon such provisions, become holders of, or continue to hold,
Guarantor Senior Indebtedness, and such provisions are made for the benefit of
the holders of Guarantor Senior Indebtedness, and such holders are made obligees
hereunder and any of them may enforce such provisions.

       Section 13.9  Subsidiary Guarantors Not to Make Payments with Respect to
                     ----------------------------------------------------------
                     Subsidiary Guarantees in Certain Circumstances.
                     ----------------------------------------------

          (a) No payment or distribution of any Property of any Subsidiary
Guarantor of any kind or character (other than Permitted Guarantor Junior
Securities) may be made by such Subsidiary Guarantor in respect of its
Subsidiary Guarantee upon (i) the happening of any default in respect of the
payment or required prepayment of any of its Guarantor Senior Indebtedness when
the same becomes due and payable (a "Subsidiary Guarantor Payment Default") and
(ii) receipt by the Trustee of written notice thereof, unless and until such
Subsidiary Guarantor Payment Default shall have been cured or waived in writing
or shall have ceased to exist or such Guarantor Senior Indebtedness shall have
been paid in full or otherwise discharged, after which (unless otherwise
prohibited pursuant to Section 13.10 hereof) such Subsidiary Guarantor shall
resume making any and all required payments in respect of its Subsidiary
Guarantee, including any missed payments.

          (b) Upon the happening of any event (other than a Subsidiary Guarantor
Payment Default) the occurrence of which entitles one or more Persons to
accelerate the maturity of any Specified Guarantor Senior Indebtedness (a
"Subsidiary Guarantor Non-payment Default"), and receipt by the applicable
Subsidiary Guarantor and the Trustee of

                                      -99-
<PAGE>

written notice thereof from one or more of the holders of such Specified
Guarantor Senior Indebtedness or their representative (a "Subsidiary Guarantor
Payment Notice"), then, unless and until such Subsidiary Guarantor Non-payment
Default shall have been cured or waived in writing or shall have ceased to exist
or such Specified Guarantor Senior Indebtedness is paid in full or otherwise
discharged or the holders (or a representative of the holders) of such Specified
Guarantor Senior Indebtedness give their written approval, no payment or
distribution shall be made by such Subsidiary Guarantor in respect of its
Subsidiary Guarantee (other than Permitted Guarantor Junior Securities);
provided, however, that these provisions will not prevent the making of any
payment for more than 179 days after a Subsidiary Guarantor Payment Notice shall
have been given after which such Subsidiary Guarantor will resume (unless
otherwise prohibited pursuant to the immediately preceding paragraph or Section
13.10 hereof) making any and all required payments in respect of its Subsidiary
Guarantee, including any missed payments. Notwithstanding the foregoing, not
more than one Subsidiary Guarantor Payment Notice shall be given with respect to
any Subsidiary Guarantee within a period of 360 consecutive days. No Subsidiary
Guarantor Non-payment Default that existed or was continuing on the date of
delivery of any Subsidiary Guarantor Payment Notice with respect to the
Specified Guarantor Senior Indebtedness initiating such Subsidiary Guarantor
Payment Notice will be, or can be, made the basis for the commencement of a
subsequent Subsidiary Guarantor Payment Notice with respect to such Subsidiary
Guarantee.

          (c) In the event that, notwithstanding the foregoing, a Subsidiary
Guarantor shall make any payment in respect of its Subsidiary Guarantee to the
Trustee or the Holder of any Security prohibited by the foregoing provisions of
this Section 13.9, then and in such event such payment shall be paid over and
delivered forthwith to the Company.  In the event that a Subsidiary Guarantor
shall make any payment in respect of its Subsidiary Guarantee to the Trustee and
the Trustee shall receive written notice of a Subsidiary Guarantor Payment
Default or a Subsidiary Guarantor Nonpayment Default from one or more of the
holders of Specified Guarantor Senior Indebtedness (or their representative)
prior to making any payment to Holders in respect of the Subsidiary Guarantee
and prior to 11:00 a.m. Eastern Time on the date which is two Business Days
prior to the date upon which by the terms hereof any money may become payable
for any purpose, such payments shall be paid over by the Trustee and delivered
forthwith to the Company.  Each Subsidiary Guarantor shall give prompt written
notice to the Trustee of any default under any of its Guarantor Senior
Indebtedness or under any agreement pursuant to which its Guarantor Senior
Indebtedness may have been issued.

       Upon any distribution of Properties of any Subsidiary Guarantor or
payment on behalf of a Subsidiary Guarantor in the event of any Insolvency or
Liquidation Proceeding with respect to such Subsidiary Guarantor:

          (a) the holders of such Subsidiary Guarantor's Guarantor Senior
Indebtedness shall be entitled to receive payment in full of such Guarantor
Senior Indebtedness, or provision must be made for such payment, before the
Holders are entitled to receive any direct or indirect payment or distribution
of any kind or character, whether in cash, property or securities (other than
Permitted Guarantor Junior Securities), on account of any payment in respect of
such Subsidiary Guarantor's Subsidiary Guarantee;

                                     -100-

          (b) any direct or indirect payment or distribution of Properties of
such Subsidiary Guarantor of any kind or character, whether in cash, property or
securities (other than a payment or distribution in the form of Permitted
Guarantor Junior Securities), by set-off or otherwise, to which the Holders or
the Trustee, on behalf of the Holders, would be entitled except for the
provisions of this Article XIII, shall be paid by the Subsidiary Guarantor or by
any liquidating trustee or agent or other Person making such payment or
distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee
or otherwise, directly to the holders of such Guarantor Senior Indebtedness or
their representative or representatives or to the trustee or trustees under any
indenture under which any instruments evidencing any of such Senior Guarantor
Indebtedness may have been issued, ratably according to the aggregate amounts
remaining unpaid on account of such Senior Guarantor Indebtedness held or
represented by each, to the extent necessary to make payment in full of all such
Guarantor Senior Indebtedness, after giving effect to any concurrent payment or
distribution to the holders of such Guarantor Senior Indebtedness; and

          (c) in the event that, notwithstanding the foregoing provisions of
this Section 13.10, any direct or indirect payment or distribution of Properties
of such Subsidiary Guarantor of any kind or character, whether in cash, property
or securities (other than a payment or distribution in the form of Permitted
Guarantor Junior Securities), shall be received by the Trustee or the Holders
before all such Guarantor Senior Indebtedness is paid in full or otherwise
discharged, such Properties shall be received and held in trust for and shall be
paid over to the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee, agent or other Person making payment or distribution of
assets of such Subsidiary Guarantor, for application to the payment of such
Guarantor Senior Indebtedness until all such Guarantor Senior Indebtedness shall
have been paid or provided for in full, after giving effect to any concurrent
payment or distribution to the holders of such Guarantor Senior Indebtedness.

       The Company or a Subsidiary Guarantor shall give prompt written notice to
the Trustee of the occurrence of any Insolvency or Liquidation Proceeding with
respect to such Subsidiary Guarantor.

                      -------------------

       After the payment in full of all Guarantor Senior Indebtedness of a
Subsidiary Guarantor, the Holders shall be subrogated (equally and ratably with
the holders of all other Indebtedness of such Subsidiary Guarantor which by its
express terms is subordinated to such Guarantor Senior Indebtedness to
substantially the same extent as such Subsidiary Guarantee is so subordinated
and which is entitled to like rights of subrogation as a result of payments made
to the holders of such Guarantor Senior Indebtedness) to the rights of the
holders of such Guarantor Senior Indebtedness to receive payments or
distributions of cash, property and securities of such Subsidiary Guarantor
applicable to such Guarantor Senior Indebtedness until all amounts owing on the
Securities shall be paid in full, and for the purpose of such subrogation no
payments or distributions to the holders of such Guarantor Senior Indebtedness
by or on behalf of such Subsidiary Guarantor or by or on behalf of the Holders
by virtue of this Article XIII which otherwise would have been made to the
Holders shall, as between such Subsidiary Guarantor, its creditors other than
the holders of Guarantor Senior Indebtedness, and the Holders of the Securities,
be deemed to be a payment or distribution by such Subsidiary

                                     -101-
<PAGE>

Guarantor to or on account of such Guarantor Senior Indebtedness, it being
understood that the subordination provisions of this Article XIII are, and are
intended solely for, the purpose of defining the relative rights of the Holders,
on the one hand, and the holders of Guarantor Senior Indebtedness, on the other
hand.

       Section 13.12  Obligations of Subsidiary Guarantors Unconditional.
                      --------------------------------------------------

       Nothing contained in this Article XIII or elsewhere in this Indenture or
in any Security is intended to or shall impair, as between the Subsidiary
Guarantors and the Holders, the obligation of the Subsidiary Guarantors under
the Subsidiary Guarantees, or is intended to or shall affect the relative rights
of the Holders and creditors of the Subsidiary Guarantors, nor shall anything
herein or therein prevent the Trustee or any Holder from exercising all remedies
otherwise permitted by applicable law upon Default under this Indenture, subject
to the rights, if any, under this Article XIII of the holders of Guarantor
Senior Indebtedness in respect of cash, property or securities of any Subsidiary
Guarantor received upon the exercise of any such remedy.  Upon any distribution
of Properties of a Subsidiary Guarantor referred to in this Article XIII, the
Trustee, subject to the provisions of Section 6.2 hereof, and the Holders of the
Securities shall be entitled to rely upon any order or decree made by any court
of competent jurisdiction in which such dissolution, winding-up, liquidation or
reorganization proceedings are pending, or a certificate of a trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, or agent or other Person making any distribution to the Trustee or
to the Holders of the Securities, for the purpose of ascertaining the Persons
entitled to participate in such distribution, the holders of the related
Guarantor Senior Indebtedness and other indebtedness of such Subsidiary
Guarantor, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article

                      Absence of Notice.
                      -----------------

       The Trustee shall not at any time be charged with knowledge of the
existence of any facts that would prohibit the making of any payment to or by
the Trustee, unless it shall have received at its Corporate Trust Office written
notice thereof from a Subsidiary Guarantor or from one or more holders of
Guarantor Senior Indebtedness or Specified Guarantor Senior Indebtedness, in the
case of a Subsidiary Guarantor Non-payment Default, or from any representative
thereof; and, prior to the receipt of any such written notice, the Trustee,
subject to TIA Sections 315(a) through 315(d), shall be entitled to assume
conclusively that no such facts exist.  The Trustee shall be entitled to rely on
the delivery to it of a written notice by a Person representing himself to be a
holder of Guarantor Senior Indebtedness or Specified Guarantor Senior
Indebtedness, in the case of a Subsidiary Guarantor Non-payment Default (or a
representative on behalf of such holder), to establish that such notice has been
given by a holder of Guarantor Senior Indebtedness or Specified Guarantor Senior
Indebtedness, in the case of a Subsidiary Guarantor Non-payment Default, or a
representative on behalf of any such holder or holders.

payment in respect

                                     -102-
<PAGE>

of the related Subsidiary Guarantee shall be subject to the provisions of
Sections 13.8, 13.9, 13.10 and 13.11 hereof except that, if prior to 11:00 a.m.
Eastern time on the date which is two Business Days prior to the date on which
by the terms of this Indenture any such money may become payable for any
purpose, the Trustee or, in the case of any such deposit of money with a Paying
Agent, the Paying Agent shall not have received with respect to such money the
notice provided for in Section 13.13 hereof, then the Trustee or such Paying
Agent, as the case may be, shall have full power and authority to receive such
money and to apply the same to the purpose for which it was received, and shall
not be affected by any notice to the contrary which may be received by it on or
after 11:00 a.m., Eastern time, two Business Days prior to such payment date. In
the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Guarantor Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article XIII, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Guarantor Senior
Indebtedness held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such Person under this Article XIII, and if such evidence is not
furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

       The Trustee, however, shall not be deemed to owe any fiduciary duty to
the holders of Guarantor Senior Indebtedness but shall have only such
obligations to such holders as are expressly set forth in this Article XIII.

       No right of any present or future holders of any Guarantor Senior
Indebtedness of a Subsidiary Guarantor to enforce subordination as provided
herein shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of such Subsidiary Guarantor or by any act or failure
to act by any such holder, or by any noncompliance by such Subsidiary Guarantor
with the terms of this Indenture, regardless of any knowledge thereof which any
such holder may have or be otherwise charged with.

       Without in any way limiting the generality of the preceding paragraph of
this Section, the holders of Guarantor Senior Indebtedness may, at any time and
from time to time, without the consent of or notice to the Trustee or the
Holders of the Securities, without incurring responsibility to the Holders of
the Securities and without impairing or releasing the subordination or other
benefits provided in this Article, or the obligations hereunder of the Holders
of the Securities to the holders of Guarantor Senior Indebtedness, do any one or
more of the following:  (1) change the manner, place or terms of payment or
extend the time of payment of, or renew, exchange, amend, increase or alter,
Guarantor Senior Indebtedness or the term of any instrument evidencing the same
or any agreement under which Guarantor Senior Indebtedness is outstanding or any
liability of any obligor thereon (unless such change, extension or alteration
results in such Indebtedness no longer being Guarantor Senior Indebtedness as
defined in this Indenture); (2) sell, exchange, release or otherwise deal with
any Property pledged, mortgaged or otherwise securing Guarantor Senior
Indebtedness; (3) settle or compromise any Guarantor Senior Indebtedness or any
liability of any obligor thereon or release any Person liable in

                                     -103-

any manner for the collection of Guarantor Senior Indebtedness; and (4) exercise
or refrain from exercising any rights against the Company and any other Person.

                      ---------------------

       Each Holder, by his acceptance thereof, authorizes and expressly directs
the Trustee on his behalf to take such action as may be necessary or appropriate
to effectuate the subordination provided in this Article XIII and appoints the
Trustee as his attorney-in-fact for such purpose, including, in the event of any
Insolvency or Liquidation Proceeding with respect to any Subsidiary Guarantor,
the immediate filing of a claim for the unpaid balance of his Securities
pursuant to the related Subsidiary Guarantee in the form required in said
proceedings and the causing of said claim to be approved.

reason of any provision in this Article XIII shall not be construed as
preventing the occurrence of an Event of Default under this Indenture.

                      -------

       For purposes of this Article XIII, a payment with respect to any

IV hereof, any payment on account of any repurchase or redemption of any
Security and any payment or recovery on any claim (whether for rescission or
damages and whether based on contract, tort, duty imposed by law, or any other
theory of liability) relating to or arising out of the offer, sale or purchase
of any Security.

                     ---------------------------------------------

       The Company covenants and agrees, and each Holder of a Security, by his
acceptance thereof, likewise covenants and agrees, for the benefit of the
holders, from time to time, of Senior Indebtedness, that, to the extent and in
the manner hereinafter set forth in this Article, the Indebtedness represented
by the Securities and the payment of the principal of (and premium, if any, on)

subordinate and subject in right of payment as provided in this Article to the
prior payment in full of all Senior Indebtedness, whether outstanding on the
date of this Indenture or thereafter created, incurred, assumed or guaranteed;
provided, however, that the Securities, the Indebtedness represented thereby and
the payment of the principal of (and premium, if any, on) and interest on the
Securities in all respects shall rank equally with, or prior to, all existing

Liquidation Proceeding with respect to the Company:

          (a) the holders of Senior Indebtedness shall be entitled to receive
payment in full of such Senior Indebtedness, or provision must be made for such
payment, before the Holders of the Securities are entitled to receive any direct
or indirect payment or distribution of any kind or character, whether in cash,
property or securities (other than Permitted Junior Securities) on account of
principal of (or premium, if any, on) or interest on the Securities or on
account of the purchase or redemption or other acquisition of Securities
(including pursuant to a Change of Control Offer or a Net Proceeds Offer); and

          (b) any direct or indirect payment or distribution of Properties of
the Company of any kind or character, whether in cash, property or securities

principal of (and premium, if any, on) or interest on the Securities before all
Senior Indebtedness is paid or provided for in full, then and in such event such
payment or distribution (other than a payment or distribution in the form of
Permitted Junior Securities) shall be received and held in trust for and shall
be paid over or delivered forthwith to the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee, agent or other Person making payment
or distribution of assets of the Company, to the extent necessary to pay all
Senior Indebtedness in full, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

       The consolidation of the Company with, or the merger of the Company into,
another Person or the liquidation or dissolution of the Company following the
sale, assignment, conveyance, transfer, lease or other disposition of all or
substantially all its Properties on a consolidated basis to another Person or
group of Affiliated Persons pursuant to, and in compliance with, the terms and
conditions set forth in Article VIII hereof shall not be deemed an Insolvency or
Liquidation Proceeding (requiring the repayment of all Senior Indebtedness in
full as a prerequisite to any payments being made to the Holders) for the
purposes of this Section.

       Section 14.3  Suspension of Payment When Senior Indebtedness in Default.
                     ---------------------------------------------------------

          (a) Upon (1) the occurrence of a Payment Event of Default and (2)
receipt by the Trustee of written notice of such occurrence, then no payment or
distribution of any Properties of the Company of any kind or character (other
than Permitted Junior Securities) shall be made by the Company on account of
principal of (or premium, if any, on) or interest on the Securities or on
account of the purchase or redemption or other acquisition of Securities unless
and until such Payment Event of Default shall have been cured or waived in
writing or shall have ceased to exist or such Specified Senior Indebtedness
shall have been paid in full or otherwise discharged, after which (unless
otherwise prohibited by Section 14.2 hereof) the Company shall resume making any
and all required payments in respect of the Securities, including any missed
payments.

          (b) Upon (1) the occurrence of a Non-payment Event of Default and (2)
receipt by the Trustee and the Company of written notice of such occurrence from
one or more of the holders of Specified Senior Indebtedness (or their
representative), then no payment or distribution of any Properties of the
Company of any kind or character (other than Permitted Junior Securities) shall
be made by the Company on account of any principal of (or premium, if any, on)
or interest on the Securities or on account of the purchase or redemption or
other acquisition of Securities for the period specified below (the "Payment
Blockage Period").  The Payment Blockage Period will commence upon the earlier
of the dates of receipt by the Trustee or the Company of such notice (the
"Payment Blockage Notice") from one or more of the holders of Specified Senior
Indebtedness (or their

                                     -106-
<PAGE>

representative) and shall end on the earliest of (i) 179 days thereafter, (ii)
the date, as set forth in a written notice from the holders of the Specified
Senior Indebtedness (or their representative) to the Company or the Trustee, on
which such Non-payment Event of Default is cured, waived in writing or ceases to
exist or such Specified Senior Indebtedness is discharged or (iii) the date on
which such Payment Blockage Period shall have been terminated by written notice
to the Company or the Trustee from one or more of the holders (or their
representative) initiating such Payment Blockage Period, after which the Company
will resume (unless otherwise prohibited pursuant to the immediately preceding
paragraph or Section 14.2 hereof) making any and all required payments in
respect of the Securities, including any missed payments. In any event, not more
than one Payment Blockage Period may be commenced during any period of 360
consecutive days. No Non-payment Event of Default that existed or was continuing
on the date of delivery of any Payment Blockage Notice to the Trustee will be,
or can be, made the basis for the commencement of a subsequent Payment Blockage
Period.

          (c) In the event that, notwithstanding the foregoing, the Company
shall make any payment to the Trustee or the Holder of any Security prohibited
by the foregoing provisions of this Section 14.3, then and in such event such
payment shall be paid over and delivered forthwith to the Company. In the event
that the Company shall make any payment in respect of the Securities to the
Trustee and the Trustee shall receive written notice of a Payment Event of
Default or a Non-payment Event of Default from one or more of the holders of
Specified Senior Indebtedness (or their representative) prior to making any
payment to Holders in respect of the Securities and prior to 11:00 a.m. Eastern
time on the date which is two Business Days prior to the date upon which by the
terms hereof any money may become payable for any purpose, such payments shall
be paid over by the Trustee and delivered forthwith to the Company.

       Section 14.4  Payment Permitted If No Default.
                     -------------------------------

       Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent the Company, at any time except during the
pendency of any Insolvency or Liquidation Proceeding referred to in Section 14.2
hereof or under the conditions described in Section 14.3 hereof, from making
payments at any time of principal of (and premium, if any, on) or interest on
the Securities.

       Section 14.5  Subrogation to Rights of Holders of Senior Indebtedness.
                     -------------------------------------------------------

       After the payment in full of all Senior Indebtedness, the Holders of the
Securities shall be subrogated (equally and ratably with the holders of all
indebtedness of the Company which by its express terms is subordinated to Senior
Indebtedness to substantially the same extent as the Securities are so
subordinated and which is entitled to like rights of subrogation as a result of
the payments made to the holders of Senior Indebtedness) to the rights of the
holders of Senior Indebtedness to receive payments and distributions of cash,
property and securities applicable to Senior Indebtedness until all amounts
owing on the Securities shall be paid in full.  For purposes of such
subrogation, no payments or distributions to the holders of Senior Indebtedness
by or on behalf of the Company or by or on behalf of the Holders by virtue of
this Article which otherwise would have been made to the Holders shall, as
between the Company, its creditors other than holders of Senior Indebtedness,
and the Holders of the Securities, be deemed to be a payment or distribution by
the Company to or on account of the Senior Indebtedness.

       Section 14.6  Provisions Solely to Define Relative Rights.
                     -------------------------------------------

       The provisions of this Article are, and are intended solely, for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Indebtedness on the other hand.  Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall (a) impair, as between the Company and the Holders of the
Securities, the obligation of the Company, which is absolute and unconditional,
to pay to the Holders of the Securities the principal of (and premium, if any,
on) and interest on the Securities as and when the same shall become due and
payable in accordance with their terms; or (b) affect the relative rights
against the Company of the Holders of the Securities and creditors of the
Company other than the holders of Senior Indebtedness; or (c) prevent the
Trustee or the Holder of any Security from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the
rights, if any, under this Article of the holders of Senior Indebtedness.

       Section 14.7  Trustee to Effectuate Subordination.
                     -----------------------------------

       Each Holder of a Security by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee as his attorney-in-fact for any and all such purposes,
including, in the event of any Insolvency or Liquidation Proceeding with respect
to the Company, the immediate filing of a claim for the unpaid balance of his
Securities pursuant to this Indenture in the form required in said proceedings
and the causing of said claim to be approved.

       Section 14.8  No Waiver of Subordination Provision.
                     ------------------------------------

          (a) No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act by any such holder, or by any non-
compliance by the Company with the terms of this Indenture, regardless of any
knowledge thereof which any such holder may have or be otherwise charged with.

          (b) Without in any way limiting the generality of paragraph (a) of
this Section, the holders of any Senior Indebtedness, in accordance with the
terms of the instrument or agreement evidencing their Senior Indebtedness, may,
at any time and from time to time, without the consent of or notice to the
Trustee or the Holders of the Securities, without incurring responsibility to
the Holders of the Securities and without impairing or releasing the
subordination or other benefits provided in this Article, or the obligations
hereunder of the Holders of the Securities to the holders of Senior
Indebtedness, do any one or more of the following: (1) change the manner, place
or terms of payment or extend the time of payment of, or renew, exchange, amend,
increase or alter, Senior Indebtedness or the terms of any instrument evidencing
the same or any agreement under which Senior Indebtedness is outstanding or any
liability of any obligor thereon (unless such change, extension, amendment,
increase or other alteration results in such Indebtedness no longer being Senior
Indebtedness as defined in this Indenture); (2) sell, exchange, release or
otherwise deal with any Property pledged, mortgaged or otherwise securing Senior
Indebtedness; (3) settle or compromise any Senior Indebtedness or any liability
of any obligor thereon or release any Person liable in any manner for the

                                     -108-
<PAGE>

collection of Senior Indebtedness; and (4) exercise or refrain from exercising
any rights against the Company and any other Person.

       Section 14.9  Notice to Trustee.
                     -----------------

          (a) The Company shall give prompt written notice to the Trustee of any
fact known to the Company which would prohibit the making of any payment to or
by the Trustee in respect of the Securities.  Notwithstanding the provisions of
this Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or one or more of the holders of Senior Indebtedness (or their
representative), with respect to a Payment Default, or one or more of the
holders of Specified Senior Indebtedness (or their representative), with respect
to a Non-payment Event of Default, or from any trustee, fiduciary or agent
therefor; and, prior to the receipt of any such written notice, the Trustee,
subject to TIA Sections 315(a) through 315(d), shall be entitled in all respects
to assume that no such facts exist; provided, however, that, if the Trustee
shall not have received the notice provided for in this Section prior to 11:00
a.m. Eastern time on the date which is two Business Days prior to the date upon
which by the terms hereof any money may become payable for any purpose
(including, without limitation, the payment of the principal of (and premium, if
any, on) or interest on any Security), then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to
receive such money and to apply the same to the purpose for which such money was
received and shall not be affected by any notice to the contrary which may be
received by it on or after 11:00 a.m. Eastern time two Business Days prior to
such payment date.

          (b) Subject to TIA Sections 315(a) through 315(d), the Trustee shall
be entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a trustee,
fiduciary or agent therefor) to establish that such notice has been given by a
holder of Senior Indebtedness (or a trustee, fiduciary or agent therefor). In
the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee, for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of
Senior Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article.

                      ----------

       Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to TIA Sections 315(a) through 315(d), and
the Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such Insolvency or
Liquidation Proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Senior Indebtedness and other indebtedness of the
Company, the amount thereof or payable

                      -----------------------------------------------------
                      Preservation of Trustee's Rights.
                      --------------------------------

       The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Indebtedness, which
may at any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.  Nothing in this Article shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 6.6 hereof.

       Section 14.12  Article Applicable to Paying Agents.
                      -----------------------------------

       In case at any time a Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting hereunder, the term "Trustee" as
used in this Article shall in such case (unless the context otherwise requires)
be construed as extending to and including such Paying Agent within its meaning
as fully for all intents and purposes as if such Paying Agent were named in this
Article in addition to or in place of the Trustee; provided, however, that
Section 14.11 hereof shall not apply to the Company or any Affiliate of the
Company if it or such Affiliate acts as Paying Agent.

       Section 14.13  No Suspension of Remedies.
                      -------------------------

       Nothing contained in this Article shall limit the right of the Trustee or
the Holders of Securities to take any action to accelerate the maturity of the
Securities pursuant to Article V hereof or to pursue any rights or remedies
hereunder or under applicable law, except as provided in Article V hereof.

       Section 14.14  Trust Money Not Subordinated.
                      ----------------------------

       Notwithstanding anything contained herein to the contrary, payments from
cash or the proceeds of U.S. Government Obligations held in trust under Article
XII hereof by the Trustee (or other qualifying trustee) and which were deposited
in accordance with the terms of Article XII hereof and not in violation of
Section 14.2 or 14.3 hereof for the payment of principal of (and premium, if
any, on) and interest on the Securities shall not be subordinated to the prior
payment of any Senior Indebtedness or subject to the restrictions set forth in
this Article XIV, and none of the Holders shall be obligated to pay over any
such amount to the Company or any holder of Senior Indebtedness or any other
creditor of the Company.

                     ------------------------------------

       Upon any application or request by the Company or any Subsidiary
Guarantor to the Trustee to take any action under any provision of this
Indenture, the Company or such Subsidiary Guarantor, as the case may be, shall
furnish to the Trustee such certificates and

                                     -110-
<PAGE>

opinions as may be required under the Trust Indenture Act or this Indenture.
Each such certificate and each such opinion shall be in the form of an Officers'
Certificate or an Opinion of Counsel, as applicable, and shall comply with the
requirements of this Indenture.

       Every certificate or opinion with respect to compliance with a condition
or covenant provided for in this Indenture shall include:

          (1) a statement that each individual signing such certificate or
     opinion has read such covenant or condition and the definitions herein
     relating thereto;

          (2) a brief statement as to the nature and scope of the examination or
     investigation upon which the statements or opinions contained in such
     certificate or opinion are based;

          (3) a statement that, in the opinion of each such individual, he has
     made such examination or investigation as is necessary to enable him to
     express an informed opinion as to whether or not such covenant or condition
     has been complied with; and

          (4) a statement as to whether, in the opinion of each such individual,
     such condition or covenant has been complied with.

       The certificates and opinions provided pursuant to this Section 15.1 and
the statements required by this Section 15.1 shall comply in all respects with
TIA Sections 314(c) and (e).

       Section 15.2  Form of Documents Delivered to Trustee.
                     --------------------------------------

       In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

       Any certificate or opinion of an officer may be based, insofar as it
relates to legal matters, upon a certificate or opinion of, or representations
by, counsel, unless such officer knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
the matters upon which his certificate or opinion is based are erroneous. Any
such Opinion of Counsel may be based, insofar as it relates to factual matters,
upon an officers' certificate, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate with respect to such matters
is erroneous.

       Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

       Section 15.3  Acts of Holders.
                     ---------------

          (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section.

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

          (d) If the Company shall solicit from the Holders of Securities any
request, demand, authorization, direction, notice, consent, waiver or other Act,
the Company may, at its option, by or pursuant to a Board Resolution, fix in
advance a record date for the determination of Holders entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act,
but the Company shall have no obligation to do so. Notwithstanding TIA Section
316(c), such record date shall be the record date specified in or pursuant to
such Board Resolution, which shall be a date not earlier than the date 30 days
prior to the first solicitation of Holders generally in connection therewith and
not later than the date such solicitation is completed. If such a record date is
fixed, such request, demand, authorization, direction, notice, consent, waiver
or other Act may be given before or after such record date, but only the Holders
of record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of
such record date, provided that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than eleven
months after the record date.

          (e) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the

                                     -112-
<PAGE>

same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof, including, without
limitation, any Series B Security exchanged for a Series A Security, 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.

                     Guarantors.
                     ----------

       Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to or filed with,

          (1) the Trustee by any Holder, the Company, any Subsidiary Guarantor
     or any holder of Senior Indebtedness or Guarantor Senior Indebtedness shall
     be sufficient for every purpose hereunder if made, given, furnished or
     filed in writing (in the English language) and delivered in person or
     mailed by certified or registered mail (return receipt requested) to the
     Trustee at its Corporate Trust Office; or

          (2) the Company or any Subsidiary Guarantor by the Trustee or by any
     Holder shall be sufficient for every purpose hereunder (unless otherwise
     herein expressly provided) if in writing (in the English language) and
     delivered in person or mailed by certified or registered mail (return
     receipt requested) to the Company or such Subsidiary Guarantor, as
     applicable, addressed to it at the Company's principal office located at
     1021 Main Street, Suite 2100, Houston, Texas 77002, or at any other address
     otherwise furnished in writing to the Trustee by the Company.

       Section 15.5  Notice to Holders; Waiver.
                     -------------------------

       Where this Indenture provides for notice of any event to Holders by the
Company, the Trustee or any Paying Agent, such notice shall be sufficiently
given (unless otherwise herein expressly provided) if in writing (in the English
language) and mailed, first-class postage prepaid, to each Holder affected by
such event, at his address as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice. In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. Any notice mailed to a Holder in the manner herein
prescribed shall be conclusively deemed to have been received by such Holder,
whether or not such Holder actually receives such notice. 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
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.

       In case by reason of the suspension of or irregularities in regular mail
service or by reason of any other cause, it shall be impracticable to mail
notice of any event to Holders when such notice is required to be given pursuant
to any provision of this Indenture, then any manner of giving such notice as
shall be satisfactory to the Trustee shall be deemed to be a sufficient giving
of such notice for every purpose hereunder.

     This Certificate relates to $_________ principal amount of Securities held
in the form of *[_] a beneficial interest in a Global Security or *[_]  Physical
Securities by _________________ (the "Transferor").

     The Transferor:*

     [_]  has requested by written order that the Security Registrar deliver in
exchange for its beneficial interest in the Global Security held by the

form of authorized denominations and in an aggregate principal amount equal to

indicated above); or

register the transfer of a Physical Security or Physical Securities.

          In connection with such request and in respect of each such Security,
the Transferor does hereby certify that the Transferor is familiar with the

transfers thereof as provided in Section 3.5 of such Indenture, and that the
transfer of these Securities does not require registration under the Securities
Act of 1933, as amended (the "Act") because *:

3.5 of the Indenture).

     [_]  Such Security is being transferred to a person whom the Transferor

144A under the Act), in reliance on Rule 144A.

     [_]  Such Security is being transferred to an institutional "accredited
investor" (within the meaning of subparagraphs (a)(1), (2), (3) or (7) of Rule
501 under the Act).

     [_]  Such Security is being transferred in reliance on Regulation S under
the Act.

     [_]  Such Security is being transferred in reliance on Rule 144 under the
Act.

with an exemption from the registration requirements of the Act other than Rule
144A or Rule 144 or Regulation S under the Act to a person other than an
institutional "accredited investor."

Ladies and Gentlemen:

     In connection with our proposed purchase of 9 3/8% Senior Subordinated
Notes due 2010, Series A, or 9 3/8% Series Notes due 2010, Series B (the
"Securities"), of Nuevo Energy Company (the "Company"), we confirm that:

     1.  We have received such information as we deem necessary in order to make
our investment decision.

     2.  We understand that any subsequent transfer of the Securities is subject
to certain restrictions and conditions set forth in the Indenture and the
undersigned agrees to be bound by, and not to resell, pledge or otherwise
transfer the Securities except in compliance with, such restrictions and
conditions and the Securities Act of 1933, as amended (the "Securities Act").

     3.  We understand that the offer and sale of the Securities have not been
registered under the Securities Act, and that the Securities may not be offered
or sold within the United States or to, or for the account or benefit of, U.S.
persons except as permitted in the following sentence.  We agree, on our own
behalf and on behalf of any accounts for which we are acting as hereinafter
stated, that if we should sell any Securities, we will do so only (A) to the
Company or any subsidiary thereof, (B) inside the United States in accordance
with Rule 144A under the Securities Act to a "qualified institutional buyer" (as
defined therein), (C) inside the United States to an institutional "accredited
investor" (as defined below) that, prior to such transfer, furnishes (or has
furnished on its behalf by a U.S. broker-dealer) to the Trustee a signed letter
substantially in the form hereof, (D) outside the United States in accordance
with Regulation S under the Securities Act, (E) pursuant to the exemption from
registration provided by Rule 144 under the Securities Act (if available), or
(F) pursuant to an effective registration statement under the Securities Act,
and we further agree to provide to any person purchasing Securities from us a
notice advising such purchaser that resales of the Securities are restricted as
stated herein.

     4.  We understand that, on any proposed resale of Securities, we will be
required to furnish to you and the Company, such certification, legal opinions
and other

                                      C-1
<PAGE>

information as you and the Company may reasonably require to confirm that the
proposed sale complies with the foregoing restrictions. We further understand
that the Securities purchased by us will bear a legend to the foregoing effect.

     5.  We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Securities, and we
and any accounts for which we are acting are each able to bear the economic risk
of our or their investment, as the case may be, for an indefinite period.

     6.  We are acquiring the Securities purchased by us for our account or for
one or more accounts (each of which is an institutional "accredited investor")
as to each of which we exercise sole investment discretion, for investment
purposes and not with a view to, or for offer or sale in connection with, any
distribution in violation of the Securities Act.

     You and the Company and yours and their respective counsel are entitled to
rely upon this letter and are irrevocably authorized to produce this letter or a
copy hereof to any interested party in any administrative or legal proceeding or
official inquiry with respect to the matters covered hereby.

          ------------------------------------------------------------------
Dealers; Private Exchange.
-------------------------

          (a)  The Company shall prepare and, not later than 90 days following
     the Closing Date, shall file with the Commission the Exchange Offer
     Registration Statement with respect to the Registered Exchange Offer. The
     Company shall use its reasonable best efforts to cause the Exchange Offer
     Registration Statement to become effective under the Act as promptly as
     practicable after the filing thereof, but in any event on or prior to 150
     days after the Closing Date.

          (b)  Unless the Registered Exchange Offer would not be permitted by a
     policy of the Commission, the Company will commence the Registered Exchange
     Offer and will use its reasonable best efforts to consummate the Registered
     Exchange Offer as promptly as practicable, but in any event on or prior to
     180 days after the Closing Date.

          (c)  Upon the effectiveness of the Exchange Offer Registration
     Statement, the Company shall promptly commence the Registered Exchange
     Offer, it being the objective of such Registered Exchange Offer to enable
     each Holder electing to exchange Securities for New Securities (assuming
     that such Holder is not an affiliate of the Company within the meaning of
     the Act, acquires the New Securities in the ordinary course of such
     Holder's business and has no arrangements with any person to participate in
     the distribution of the New Securities) to trade such New Securities from

     Act.

          (d)  In connection with the Registered Exchange Offer, the Company
     shall:

               (i)   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;

               (ii)  keep the Registered Exchange Offer open for not less than
          30 days (or longer if required by applicable law) after the date
          notice thereof is mailed to the Holders;

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

               (iv)  comply in all respects with all applicable laws.

          (e)  As soon as practicable after the close of the Registered Exchange
     Offer, the Company shall:

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

                                      -4-
<PAGE>

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

               (iii) cause the Trustee promptly to authenticate and deliver to
          each Holder of Securities New Securities equal in principal amount to
          the Securities of such Holder so accepted for exchange.

          (f)  The Initial Purchasers and the Company acknowledge that, pursuant
     to interpretations by the Commission's staff of Section 5 of the Act, and
     in the absence of an applicable exemption therefrom, each Exchanging Dealer
     is required to deliver a Prospectus in connection with a sale of any New
     Securities received by such Exchanging Dealer pursuant to the Registered
     Exchange Offer in exchange for Securities acquired for its own account as a
     result of market-making activities or other trading activities.
     Accordingly, the Company shall:

               (i)   include the information set forth in Annex A hereto on the
          cover of the Exchange Offer Registration Statement, in Annex B hereto
          in the forepart of the Exchange Offer Registration Statement in a
          section setting forth details of the Exchange Offer, and in Annex C
          hereto in the underwriting or 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 Registered
          Exchange Offer; and

               (ii)  use its best efforts to keep the Exchange Offer
          Registration Statement continuously effective under the Act during the
          Exchange Offer Registration Period for delivery by Exchanging Dealers
          in connection with sales of New Securities received pursuant to the
          Registered Exchange Offer, as contemplated by Section 4(h) below.

          (g)  In the event that any Initial Purchaser determines that it is not
     eligible to participate in the Registered Exchange Offer with respect to
     the exchange of Securities constituting any portion of an unsold allotment,
     at the request of such Initial Purchaser, the Company shall issue and
     deliver to such Initial Purchaser or the party purchasing New Securities
     registered under a Shelf Registration Statement as contemplated by Section
     3 hereof from such Initial Purchaser, in exchange for such Securities, a
     like principal amount of New Securities. The Company shall seek to cause
     the CUSIP Service Bureau to issue the same CUSIP number for such New
     Securities as for New Securities issued pursuant to the Registered Exchange
     Offer.

     3.   Shelf Registration. If (i) because of any change in law or applicable
          ------------------
interpretations thereof by the Commission's staff, the Company determines upon
advice of its outside counsel that it is not permitted to effect the Registered
Exchange Offer as contemplated by Section 2 hereof, or (ii) for any other reason
the Exchange Offer Registration Statement is not declared effective within 150
days after the Closing Date or the Registered Exchange Offer is not consummated
within 180 days after the Closing Date, or (iii) if any Initial Purchaser so
requests with respect to Securities (or any New Securities received pursuant to
Section 2(f)) not eligible to be exchanged for New

                                      -5-
<PAGE>

Securities in a Registered Exchange Offer or, in the case of any Initial
Purchaser that participates in any Registered Exchange Offer, such Initial
Purchaser does not receive freely tradeable New Securities, or (iv) if any
Holder (other than an Initial Purchaser) is not eligible to participate in the
Registered Exchange Offer or such Holder does not receive freely tradeable New
Securities in the Registered Exchange Offer other than by reason of such Holder
being an affiliate of the Company (it being understood that, for purposes of
this Section 3, (x) the requirement that an Initial Purchaser deliver a
Prospectus containing the information required by Items 507 and/or 508 of
Regulation S-K under the Act in connection with sales of New Securities acquired
in exchange for such Securities shall result in such New Securities being not
"freely tradeable" but (y) the requirement that an Exchanging Dealer deliver a
Prospectus in connection with sales of New Securities acquired in the Registered
Exchange Offer in exchange for Securities acquired as a result of market-making
activities or other trading activities shall not result in such New Securities
being not "freely tradeable"), or (v) any applicable law or interpretations do
not permit any Holder of Securities to participate in the Registered Exchange
Offer, or (vi) the Company so elects, the following provisions shall apply:

          (a)  The Company shall as promptly as practicable (but in no event
     more than 30 days after so required or requested pursuant to this Section
     3) file with the Commission and thereafter shall use its reasonable best
     efforts to cause to be declared effective under the Act as promptly as
     practicable after the filing thereof, a Shelf Registration Statement
     relating to Transfer Restricted Securities by the Holders from time to time
     in accordance with the methods of distribution elected by such Holders and
     set forth in such Shelf Registration Statement; provided, that with respect
     to New Securities received by an Initial Purchaser in exchange for
     Securities constituting any portion of an unsold allotment, the Company
     may, if permitted by current interpretations by the Commission's staff,
     file a post-effective amendment to the Exchange Offer Registration
     Statement containing the information required by Regulation S-K Items 507
     and/or 508, as applicable, in satisfaction of its obligations under this
     paragraph (a) with respect thereto, and any such Exchange Offer
     Registration Statement, as so amended, shall be referred to herein as, and
     governed by the provisions herein applicable to, a Shelf Registration
     Statement.

          (b)  The Company shall use its reasonable best efforts to keep the
     Shelf Registration Statement continuously effective in order to permit the
     Prospectus forming part thereof to be usable by Holders for a period of two
     years after the Closing Date or such shorter period that will terminate
     when all the Transfer Restricted Securities covered by the Shelf
     Registration Statement have been sold pursuant to the Shelf Registration
     Statement (in any such case, such period being called the "Shelf
     Registration Period"). The Company shall be deemed not to have used its
     reasonable best efforts to keep the Shelf Registration Statement effective
     during the requisite period if it voluntarily takes 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 (i) such action is required by applicable law, or (ii)
     such action is taken by the Company in good faith and for valid business
     reasons (not including avoidance of the Company's obligations hereunder),
     including the acquisition or divestiture of assets, so long as the Company
     promptly thereafter complies with the requirements of Section 4(k) hereof,
     if applicable.

                                      -6-
<PAGE>

For so long as any Transfer Restricted Securities are outstanding, the Company
will continue to provide to holders of the Securities and to prospective
purchasers of the Securities the information required by Rule 144A(d)(4) under
the Securities Act.

Statement, the following provisions shall apply:

          (a)  The Company shall furnish to you, prior to the filing thereof
     with the Commission, a copy of any Shelf Registration Statement and any
     Exchange Offer Registration Statement, and each amendment thereof and each
     amendment or supplement, if any, to the Prospectus included therein and

     any amendment thereto and any Prospectus forming part thereof and any
     amendment or supplement thereto complies in all material respects with the
     Act and the rules and regulations thereunder, (ii) any 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
     Registration Statement, and any amendment or supplement to such Prospectus,
     does not include an untrue statement of a material fact or omit to state a
     material fact necessary in order to make the statements, in the light of
     the circumstances under which they were made, not misleading.

          Registration Statement, the Holders of securities covered thereby,
          and, if requested by you or any such Holder, confirm such advice in

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

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

               (2)  The Company shall advise you and, in the case of a Shelf
          Registration Statement, the Holders of securities covered thereby,

          advice in writing:

<PAGE>

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

                    (ii)  of the receipt by the Company of any notification with
               respect to the suspension of the qualification of the securities
               included therein for sale in any jurisdiction or the initiation
               or threatening of any proceeding for such purpose; and

                    (iii) of the happening of any event that requires the making
               of any changes in the Registration Statement or the Prospectus so
               that, as of such date, 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 (in the case
               of the Prospectus, in light of the circumstances under which they
               were made) not misleading (which advice shall be accompanied by
               an instruction to suspend the use of the Prospectus until the
               requisite changes have been made).

          (d)  The Company shall use its best efforts to obtain the withdrawal
     of any order suspending the effectiveness of any Registration Statement at
     the earliest possible time.

     within the coverage of any Shelf Registration Statement, without charge, at

     amendment thereto, including financial statements and schedules, and, if
     the Holder so requests in writing, all exhibits (including those
     incorporated by reference).

          (f)  The Company shall, during the Shelf Registration Period, deliver
     to each Holder of 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 the Prospectus
     or any amendment or supplement thereto by each of the selling Holders of
     securities in connection with the offering and sale of the securities
     covered by the Prospectus or any amendment or supplement thereto.

          (g)  The Company shall furnish to each Exchanging Dealer which so
     requests, without charge, at least one copy of the Exchange Offer
     Registration Statement and any post-effective amendment thereto, including
     financial statements and schedules, any documents incorporated by reference
     therein, and, if the Exchanging Dealer so requests in writing, all exhibits
     (including those incorporated by reference).

          (h)  The Company shall, if required under applicable securities laws,
     during the Exchange Offer Registration Period, promptly deliver to each
     Exchanging Dealer, without charge, as many copies of the Prospectus
     included in such Exchange Offer Registration Statement and any amendment or
     supplement thereto as such Exchanging Dealer may

                                      -8-
<PAGE>

     reasonably request in writing for delivery by such Exchanging Dealer in
     connection with a sale of New Securities received by it pursuant to the
     Registered Exchange Offer; and the Company consents to the use of the
     Prospectus or any amendment or supplement thereto by any such Exchanging
     Dealer, as aforesaid.

          (i)  Prior to the Registered Exchange Offer or any other offering of
     securities pursuant to any Registration Statement, the Company shall
     register or qualify or cooperate with the Holders of securities included
     therein and their respective counsel in connection with the registration or
     qualification of such securities for offer and sale under the securities or
     blue sky laws of such jurisdictions as any such Holders reasonably request
     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
     covered by such Registration Statement; provided, however, that the Company
     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.

          (j)  The Company shall cooperate with the Holders of Securities to
     facilitate the timely preparation and delivery of certificates representing
     Securities to be sold pursuant to any Registration Statement free of any
     restrictive legends and in such denominations and registered in such names
     as Holders may request prior to sales of securities pursuant to such
     Registration Statement.

          (k)  Upon the occurrence of any event contemplated by paragraph
     (c)(2)(iii) above, the Company shall promptly prepare a post-effective
     amendment to any Registration Statement or an amendment or supplement to
     the related Prospectus or file any other required document so that, as
     thereafter delivered to purchasers of the securities included therein, the
     Prospectus will not include an untrue statement of a material fact or omit
     to state any material fact necessary to make the statements therein, in the
     light of the circumstances under which they were made, not misleading.

          (l)  Not later than the effective date of any such Registration
     Statement hereunder, the Company shall provide a CUSIP number for the
     Securities or New Securities, as the case may be, registered under such
     Registration Statement, and provide the Trustee with printed certificates
     for such Securities or New Securities, in a form eligible for deposit with
     The Depository Trust Company.

          (m)  The Company shall use its best efforts to comply with all
     applicable rules and regulations of the Commission and shall make generally
     available to its security holders as soon as practicable after the
     effective date of the applicable Registration Statement an earnings
     statement satisfying the provisions of Section 11(a) of the Act.

          (n)  The Company shall cause the Indenture to be qualified under the
     Trust Indenture Act of 1939, as amended, in a timely manner.

          (o)  The Company may require each Holder of securities to be sold
     pursuant to any Shelf Registration Statement to furnish to the Company such
     information regarding the

                                      -9-
<PAGE>

     Holder and the distribution of such securities as the Company may from time
     to time reasonably require for inclusion in such Registration Statement.

          (p)  The Company shall, if requested, promptly incorporate in a
     Prospectus supplement or post-effective amendment to a Shelf Registration
     Statement, such information as the Managing Underwriters and Majority
     Holders reasonably agree should be included therein and shall make all
     required filings of such Prospectus supplement or post-effective amendment
     as soon as notified of the matters to be incorporated in such Prospectus
     supplement or post-effective amendment.

          (q)  In the case of any Shelf Registration Statement, the Company
     shall enter into such agreements (including underwriting agreements) and
     take all other appropriate actions in order to expedite or facilitate the
     registration or the disposition of the Securities, and in connection
     therewith, if an underwriting agreement is entered into, cause the same to
     contain indemnification provisions and procedures no less favorable than
     those set forth in Section 7 (or such other provisions and procedures
     acceptable to the Majority Holders and the Managing Underwriters, if any),
     with respect to all parties to be indemnified pursuant to Section 7 from
     Holders of Securities to the Company.

          (r)  In the case of any Shelf Registration Statement, the Company
     shall (i) make reasonably available for inspection by the Holders of
     securities to be registered thereunder, any underwriter participating in
     any disposition pursuant to such Registration Statement, and any attorney,
     accountant or other agent retained by the Holders or any such underwriter
     all relevant financial and other records, pertinent corporate documents and
     properties of the Company and its subsidiaries; (ii) cause the Company's
     officers, directors and employees to supply all relevant information
     reasonably requested by the Holders or any such underwriter, attorney,
     accountant or agent in connection with any such Registration Statement as
     is customary for similar due diligence examinations; provided, however,
     that any information that is designated in writing by the Company, in good
     faith, as confidential at the time of delivery of such information shall be
     kept confidential by the Holders or any such underwriter, attorney,
     accountant or agent, unless such disclosure is made in connection with a
     court proceeding or required by law, or such information becomes available
     to the public generally or through a third party without an accompanying
     obligation of confidentiality; (iii) make such representations and
     warranties to the Holders of securities registered thereunder and the
     underwriters, if any, in form, substance and scope as are customarily made
     by issuers to underwriters in primary underwritten offerings and covering
     matters including, but not limited to, those set forth in the Purchase
     Agreement; (iv) obtain opinions of counsel to the Company and updates
     thereof (which counsel and opinions (in form, scope and substance) shall be
     reasonably satisfactory to the Managing Underwriters, if any) addressed to
     each selling Holder and the underwriters, if any, covering such matters as
     are customarily covered in opinions requested in underwritten offerings and
     such other matters as may be reasonably requested by such Holders and
     underwriters; (v) obtain "cold comfort" letters and updates thereof from
     the independent certified public accountants of the Company (and, if
     necessary, any other independent certified public accountants of any
     subsidiary of the Company or of any business acquired by the Company for
     which financial statements and financial data are, or are required to be,
     included in the Registration Statement), addressed

                                      -10-
<PAGE>

     to each selling Holder of securities registered thereunder and the
     underwriters, if any, in customary form and covering matters of the type
     customarily covered in "cold comfort" letters in connection with primary
     underwritten offerings; and (vi) deliver such documents and certificates as
     may be reasonably requested by the Majority Holders and the Managing
     Underwriters, if any, including those to evidence compliance with Section
     4(k) and with any customary conditions contained in the underwriting
     agreement or other agreement entered into by the Company. The foregoing
     actions set forth in clauses (iii), (iv), (v) and (vi) of this Section 4(r)
     shall be performed at (A) the effectiveness of such Registration Statement
     and each post-effective amendment thereto and (B) each closing under any
     underwriting or similar agreement as and to the extent required thereunder.

          (s)  In the case of any Exchange Offer Registration Statement, the
     Company shall (i) make reasonably available for inspection by such Initial
     Purchaser, and any attorney, accountant or other agent retained by such
     Initial Purchaser, all relevant financial and other records, pertinent
     corporate documents and properties of the Company and its subsidiaries;
     (ii) cause the Company's officers, directors and employees to supply all
     relevant information reasonably requested by such Initial Purchaser or any
     such attorney, accountant or agent in connection with any such Registration
     Statement as is customary for similar due diligence examinations; provided,
     however, that any information that is designated in writing by the Company,
     in good faith, as confidential at the time of delivery of such information
     shall be kept confidential by such Initial Purchaser or any such attorney,
     accountant or agent, unless such disclosure is made in connection with a
     court proceeding or required by law, or such information becomes available
     to the public generally or through a third party without an accompanying
     obligation of confidentiality; (iii) make such representations and
     warranties to such Initial Purchaser, in form, substance and scope as are
     customarily made by issuers to underwriters in primary underwritten
     offerings and covering matters including, but not limited to, those set
     forth in the Purchase Agreement; (iv) obtain opinions of counsel to the
     Company and updates thereof (which counsel and opinions (in form, scope and
     substance) shall be reasonably satisfactory to such Initial Purchaser and
     its counsel), addressed to such Initial Purchaser, covering such matters as
     are customarily covered in opinions requested in underwritten offerings and
     such other matters as may be reasonably requested by such Initial Purchaser
     or its counsel; (v) obtain "cold comfort" letters and updates thereof from
     the independent certified public accountants of the Company (and, if
     necessary, any other independent certified public accountants of any
     subsidiary of the Company or of any business acquired by the Company for
     which financial statements and financial data are, or are required to be,
     included in the Registration Statement), addressed to such Initial
     Purchaser, in customary form and covering matters of the type customarily
     covered in "cold comfort" letters in connection with primary underwritten
     offerings, or if requested by such Initial Purchaser or its counsel in lieu
     of a "cold comfort" letter, an agreed-upon procedures letter under
     Statement on Auditing Standards No. 35, covering matters requested by such
     Initial Purchaser or its counsel; and (vi) deliver such documents and
     certificates as may be reasonably requested by such Initial Purchaser or
     its counsel, including those to evidence compliance with Section 4(k) and
     with conditions customarily contained in underwriting agreements. The
     foregoing actions set forth in clauses (iii), (iv), (v), and (vi) of this
     Section 4(s) shall be performed at the close of the Registered Exchange
     Offer and on the

                                      -11-
<PAGE>

     effective date of any post-effective amendment to the Exchange Offer
     Registration Statement.

     5.   Special Interest. The parties hereto agree that the Holders of the
          ----------------
Securities will suffer damages, and that it would not be feasible to ascertain
the extent of such damages with precision, if (i) a Registration Statement is
not filed with the Commission on or prior to 90 days after the Closing Date,
(ii) the Exchange Offer Registration Statement or a Shelf Registration
Statement, if applicable, is not declared effective on or prior to 150 days
after the Closing Date, (iii) the Registered Exchange Offer is not consummated
on or prior to 180 days after the Closing Date or (iv) a Registration Statement
is filed and declared effective on or prior to 150 days after the Closing Date
but shall thereafter cease to be effective or usable (at any time that the
Company is obligated to maintain the effectiveness thereof) in connection with
resales of Securities or New Securities without being succeeded immediately by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself declared effective on or prior to the date specified for such
effectiveness in this Agreement (each such event referred to in clauses (i)
through (iv), a "Registration Default"), Special Interest will accrue on the
Securities and the New Securities (in addition to the stated interest on the
Securities and the New Securities) from and including the date on which the
first such Registration Default shall occur to but excluding the date on which
all Registration Defaults have been cured. Special Interest will accrue at a
rate of 0.5% per annum during the 90-day period immediately following the
occurrence of the first such Registration Default and shall increase by 0.25%
per annum at the end of each subsequent 90-day period, but in no event shall
such rate exceed 1.00% per annum. All accrued Special Interest shall be paid to
Holders in the same manner as interest payments on the Securities on semi-annual
payment dates which correspond to interest payment dates for the Securities.
Following the cure of all Registration Defaults, the accrual of Special Interest
will cease.

     The parties hereto agree that the Special Interest provided for in this
Section 5 constitutes a reasonable estimate of the damages that may be incurred
by Holders of Securities by reason of the occurrence of a Registration Default.

     6.   Registration Expenses. The Company shall bear all expenses incurred in
          ---------------------
connection with the performance of its obligations under Sections 2, 3 and 4
hereof and, in the event of any Shelf Registration Statement, will reimburse the
Holders for the reasonable fees and disbursements of one firm or counsel
designated by the Majority Holders to act as counsel for the Holders in
connection therewith, and, in the case of any Exchange Offer Registration
Statement, will reimburse the Initial Purchasers for the reasonable fees and
disbursements of counsel acting in connection therewith.

     7.   Indemnification and Contribution. (a) In connection with any
          --------------------------------
Registration Statement, the Company agrees to indemnify and hold harmless each
Holder of securities covered thereby (including each Initial Purchaser and, with
respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each
Exchanging Dealer), the directors, officers, employees and agents of each such
Holder and each person who controls any such Holder within the meaning of either
the Act or the Exchange Act against any and all losses, claims, damages or
liabilities, joint or several, to which they or any of them may become subject
under the Act, the Exchange Act or other Federal or state statutory law or
regulation, at common law or otherwise, insofar as such losses,

                                      -12-
<PAGE>

claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of a material
fact contained in the Registration Statement as originally filed or in any
amendment thereof, or in any preliminary Prospectus or Prospectus, or in any
amendment thereof or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
agrees to reimburse each such indemnified party, as incurred, for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the Company will not be liable in any case to the extent that any such
loss, claim, damage or liability arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made
therein in reliance upon and in conformity with written information furnished to
the Company by or on behalf of any such Holder specifically for inclusion
therein. This indemnity agreement will be in addition to any liability which the
Company may otherwise have.

     The Company also agrees to indemnify or contribute to Losses (as defined
below) of, as provided in Section 7(d), any underwriters of Securities
registered under a Shelf Registration Statement, their officers and directors
and each person who controls such underwriters on substantially the same basis
as that of the indemnification of the Initial Purchasers and the selling Holders
provided in this Section 7(a) and shall, if requested by any Holder, enter into
an underwriting agreement reflecting such agreement, as provided in Section 4(q)
hereof.

     (b)  Each Holder of securities covered by a Registration Statement
(including each Initial Purchaser and, with respect to any Prospectus delivery
as contemplated in Section 4(h) hereof, each Exchanging Dealer) severally agrees
to indemnify and hold harmless (i) the Company, (ii) each of its directors,
(iii) each of its officers who signs such Registration Statement and (iv) each
person who controls the Company within the meaning of either the Act or the
Exchange Act to the same extent as the foregoing indemnity from the Company to
each such Holder, but only with reference to written information relating to
such Holder furnished to the Company by or on behalf of such Holder specifically
for inclusion in the documents referred to in the foregoing indemnity. This
indemnity agreement will be in addition to any liability which any such Holder
may otherwise have.

     (c)  Promptly after receipt by an indemnified party under this Section 7 or
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 7, notify the indemnifying party in writing of the commencement thereof;
but the failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided in paragraph (a) or (b)
above. The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, however, that such counsel shall be
satisfactory to the indemnified party. Notwithstanding the indemnifying party's
election to appoint counsel to represent the indemnified party in an action, the
indemnified party shall have the right to employ separate counsel

                                      -13-
<PAGE>

(including local counsel), and the indemnifying party shall bear the reasonable
fees, costs and expenses of such separate counsel (and local counsel) if (i) the
use of counsel chosen by the indemnifying party to represent the indemnified
party would present such counsel with a conflict of interest, (ii) the actual or
potential defendants in, or targets of, any such action include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be legal defenses available to it
and/or other indemnified parties which are different from or additional to those
available to the indemnifying party, (iii) the indemnifying party shall not have
employed counsel satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of the institution of
such action or (iv) the indemnifying party shall authorize the indemnified party
to employ separate counsel at the expense of the indemnifying party. An
indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.

     (d)  In the event that the indemnity provided in paragraph (a) or (b) of
this Section 7 is unavailable to or insufficient to hold harmless an indemnified
party for any reason, then each applicable indemnifying party, in lieu of
indemnifying such indemnified party, shall have a joint and several obligation
to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending same) (collectively "Losses") to which such
indemnified party may be subject in such proportion as is appropriate to reflect
the relative benefits received by such indemnifying party, on the one hand, and
such indemnified party, on the other hand, from the Initial Placement and the
Registration Statement which resulted in such Losses; provided, however, that in
no case shall any Initial Purchaser or any subsequent Holder of any Security or
New Security be responsible, in the aggregate, for any amount in excess of the
purchase discount or commission applicable to such Security, or in the case of a
New Security, applicable to the Security which was exchangeable into such New
Security, as set forth on the cover page of the Final Memorandum, nor shall any
underwriter be responsible for any amount in excess of the underwriting discount
or commission applicable to the securities purchased by such underwriter under
the Registration Statement which resulted in such Losses. If the allocation
provided by the immediately preceding sentence is unavailable for any reason,
the indemnifying party and the indemnified party shall contribute in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of such indemnifying party, on the one hand, and such
indemnified party, on the other hand, in connection with the statements or
omissions which resulted in such Losses as well as any other relevant equitable
considerations. Benefits received by the Company shall be deemed to be equal to
the sum of (x) the total net proceeds from the Initial Placement (before
deducting expenses) as set forth on the cover page of the Final Memorandum and
(y) the total amount of additional interest which the Company was not required
to pay as a result of registering the securities covered by the Registration
Statement which resulted in such Losses. Benefits received by the Initial
Purchasers shall be deemed to be equal to the total purchase discounts and
commissions as set forth on the cover page of the Final Memorandum, and benefits
received by any other Holders shall be deemed to be equal to the value of
receiving Securities or New Securities, as applicable, registered under the Act.
Benefits received by any underwriter shall be deemed to be

                                      -14-
<PAGE>

equal to the total underwriting discounts and commissions, as set forth on the
cover page of the Prospectus forming a part of the Registration Statement which
resulted in such Losses. Relative fault shall be determined by reference to
whether any alleged untrue statement or omission relates to information provided
by the indemnifying party, on the one hand, or by the indemnified party, on the
other hand. The parties agree that it would not be just and equitable if
contribution were determined by the pro rata allocation or any other method of
allocation which does not take account of the equitable considerations referred
to above. Notwithstanding the provisions of this paragraph (d), no person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 7, each person who
controls a Holder within the meaning of either the Act or the Exchange Act and
each director, officer, employee and agent of such Holder shall have the same
rights to contribution as such Holder, and each person who controls the Company
within the meaning of either the Act or the Exchange Act, each officer of the
Company who shall have signed the Registration Statement and each director of
the Company shall have the same rights to contribution as the Company, subject
in each case to the applicable terms and conditions of this paragraph (d).

     (e)  The provisions of this Section 7 will remain in full force and effect,
regardless of any investigation made by or on behalf of any Holder or the
Company or any of the officers, directors or controlling persons referred to in
this Section 7, and will survive the sale by a Holder of securities covered by a
Registration Statement.

     8.   Miscellaneous.
          -------------

          (a)  No Inconsistent Agreements.  The Company has not, as of the date
               --------------------------
     hereof, entered into, nor shall it, on or after the date hereof, enter
     into, any agreement with respect to its securities that is inconsistent
     with the rights granted to the Holders herein or otherwise conflicts with
     the provisions hereof.

          (b)  Amendments and Waivers. The provisions of this Agreement,
               ----------------------
     including the provisions of this sentence, may not be amended, qualified,
     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 the Holders of at least a majority of the then
     outstanding aggregate principal amount of Securities (or, after the
     consummation of any Exchange Offer in accordance with Section 2 hereof, of
     New Securities); provided, that with respect to any matter that directly or
     indirectly affects the rights of any Initial Purchaser hereunder, the
     Company shall obtain the written consent of each such Initial Purchaser
     against which such amendment, qualification, supplement, waiver or consent
     is to be effective. Notwithstanding the foregoing (except the foregoing
     proviso), a waiver or consent to departure from the provisions hereof with
     respect to a matter that relates exclusively to the rights of Holders whose
     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 the Majority Holders, determined on the basis of securities being
     sold rather than registered under such Registration Statement.

                                      -15-

     communications.

          (d)  Successors and Assigns. This Agreement shall inure to the benefit
               ----------------------
     of and be binding upon the successors and assigns of each of the parties,
     including, without the need for an express assignment or any consent by the
     Company thereto, subsequent Holders of Securities and/or New Securities.
     The Company hereby agrees to extend the benefits of this Agreement to any
     Holder of Securities and/or New Securities and any such Holder may
     specifically enforce the provisions of this Agreement as if an original
     party hereto.

          (e)  Counterparts.  This agreement may be executed in any number of
               -------------

Each broker-dealer that receives New 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 New 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 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 New
Securities received in exchange for Securities where such New Securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities.  The Company has agreed that, if required under applicable
securities laws and upon prior written request, it will make this Prospectus
available to any broker-dealer for use in connection with any such resale for a
period of 90 days after the consummation of the Exchange Offer.  See "Plan of
Distribution."

Each broker-dealer that receives New 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 New
Securities.  See "Plan of Distribution."

                             PLAN OF DISTRIBUTION

     Each broker-dealer that receives New 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 New 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 New 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 90 days after the consummation of the Exchange Offer, it
will make this Prospectus, as amended or supplemented, available to any broker-
dealer for use in connection with any such resale, if required under applicable
securities laws and upon prior written request.  In addition, until
_______________, ______, all dealers effecting transactions in the New
Securities may be required to deliver a prospectus.*

     The Company will not receive any proceeds from any sale of New Securities
by broker-dealers.  New 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 New 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 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 and/or the purchasers of any such New Securities.  Any broker-
dealer that resells New 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 New Securities may be deemed to be an "underwriter" within the
meaning of the Act and any profit of any such resale of New Securities and any
commissions or concessions received by any such persons may be deemed to be
underwriting compensation under the 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 Act.

     For a period of 90 days after the consummation of the Exchange Offer, 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
brokers or dealers and will indemnify the holders of the Securities (including
any broker-dealers) against certain liabilities, including liabilities under the
Act.

     [If applicable, add information required by Regulation S-K Items 507 and/or
508.]
