                                    INDENTURE dated as of December 10, 2001,
                           between STONE ENERGY CORPORATION, a Delaware
                           corporation (the "Company"), and JPMorgan Chase Bank,
                           as Trustee (the "Trustee").

                  Each party agrees as follows for the benefit of the other
party and for the equal and ratable benefit of the Holders of the Company's 8
1/4% Senior Subordinated Notes due 2011, to be issued, from time to time, in one
or more series as in this Indenture provided (the "Initial Securities") and, if
and when issued pursuant to a registered or private exchange for the Initial
Securities, the Company's 8 1/4% Senior Subordinated Notes due 2011 (the
"Exchange Securities" and, together with the Initial Securities, the
"Securities"):

                                   ARTICLE 1

                   Definitions and Incorporation by Reference

                  SECTION 1.01 Definitions.

                  "Additional Assets" means (i) any Property (other than cash,
Permitted Short-Term Investments or securities) used in the Oil and Gas Business
or any business ancillary thereto, (ii) Investments in any other Person engaged
in the Oil and Gas Business or any business ancillary thereto (including the
acquisition from third parties of Capital Stock of such Person) as a result of
which such other Person becomes a Restricted Subsidiary in compliance with
Section 4.15, (iii) the acquisition from third parties of Capital Stock of a
Restricted Subsidiary or (iv) Permitted Business Investments.

                  "Adjusted Consolidated Net Tangible Assets" means (without
duplication), as of the date of determination, the remainder of:

                  (i) the sum of (a) discounted future net revenues from proved
         oil and gas reserves of the Company and its Restricted Subsidiaries
         calculated in accordance with Commission guidelines before any state,
         federal or foreign income taxes, as estimated by the Company and
         confirmed by a reputable firm of independent petroleum engineers in a
         reserve report prepared as of the end of the Company's most recently
         completed fiscal year for which audited financial statements are
         available, as increased by, as of the date of determination, the
         estimated discounted future net revenues from (1) estimated proved oil
         and gas reserves acquired since such year-end, which reserves were not
         reflected in such year-end reserve report, and (2) estimated oil and
         gas reserves attributable to upward revisions of estimates of proved
         oil and gas reserves since such year-end due to exploration,
         development or exploitation activities, in each case calculated in
         accordance with Commission

<PAGE>

         guidelines (utilizing the prices utilized in such year-end reserve
         report), and decreased by, as of the date of determination, the
         estimated discounted future net revenues from (3) estimated proved oil
         and gas reserves produced or disposed of since such year-end and (4)
         estimated oil and gas reserves attributable to downward revisions of
         estimates of proved oil and gas reserves since such year-end due to
         changes in geological conditions or other factors which would, in
         accordance with standard industry practice, cause such revisions, in
         each case calculated in accordance with Commission guidelines
         (utilizing the prices utilized in such year-end reserve report);
         provided that, in the case of each of the determinations made pursuant
         to clauses (1) -------- through (4), such increases and decreases shall
         be as estimated by the Company's petroleum engineers, (b) the
         capitalized costs that are attributable to oil and gas properties of
         the Company and its Restricted Subsidiaries to which no proved oil and
         gas reserves are attributable, based on the Company's books and records
         as of a date no earlier than the date of the Company's latest annual or
         quarterly financial statements, (c) the Net Working Capital on a date

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 an agent 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 105.

                  (b) The ownership of Securities shall be proved by the
Security Register.

                  (c) Any request, demand, authorization, direction, notice,
consent, waiver or other Act by the Holder of any Security shall bind every
future Holder of the same Security or the Holder of every Security issued upon
the transfer thereof or in exchange therefor or in lieu thereof, in respect of
anything done, suffered or omitted to be done by the Trustee, any Paying Agent
or the Company, any Subsidiary Guarantor or any other obligor of the Securities
in reliance thereon, whether or not notation of such action is made upon such
Security.

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

                  (e) If the Company shall solicit from the Holders 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 such 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 Trust
Indenture Act Section 316(c), any such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not
more than 30 days prior to the first solicitation of Holders generally in
connection therewith and no later than the date such first 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 purposes of
determining whether Holders of the requisite proportion of Securities then
Outstanding have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for this
purpose the Securities then Outstanding shall be computed as of such record
date; provided that no such request, demand,

authorization, direction, notice, consent, waiver or other Act 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 six months after
such record date.

                  (f) For purposes of this Indenture, any action by the Holders
which may be taken in writing may be taken by electronic means or as otherwise
reasonably acceptable to the Trustee.

                  SECTION 1.06 Separability Clause. In case any provision in
this Indenture or in the Securities or Subsidiary Guarantees, if any, shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

                  SECTION 1.07 Independence of Covenants. Unless otherwise
provided herein, all covenants and agreements in this Indenture shall be given
independent effect so that if a particular action or condition is not permitted
by any such covenants, the fact that it would be permitted by an exception to,
or be otherwise within the limitations of, another covenant shall not avoid the
occurrence of a Default or an Event of Default if such action is taken or
condition exists.

                                   ARTICLE 2

                                 The Securities

                  SECTION 2.01 Amount of Securities; Issuable in Series. The
aggregate principal amount of Securities which may be authenticated and
delivered under this Indenture is unlimited. All Securities shall be identical
in all respects other than issue price and issuance dates and as to
denomination. The Securities may be issued in one or more series; provided,
however, that any Securities issued with original issue discount ("OID") for
Federal income tax purposes shall not be issued as part of the same series as
any Securities that are issued with a different amount of OID or are not issued
with OID.

                  Subject to Section 2.03, the Trustee shall authenticate
Securities for original issue on the Issue Date in the aggregate principal
amount of $200,000,000 (the "Original Securities"). With respect to any
Securities issued after the Issue Date (except for Securities authenticated and
delivered upon registration of transfer of, or in exchange for, or in lieu of,
other Securities pursuant to Section 2.07, 2.08, 2.09 or 3.06 or Appendix A),
there shall be established in or pursuant to a resolution of the Board of
Directors and, subject to Section 2.03, set forth or determined in the manner
provided in an Officer's Certificate, or established in one or more indentures
supplemental hereto, prior to the issuance of such Securities:

                           (1) whether such Securities shall be issued as part
                  of a new or existing series of Securities and the title of
                  such Securities (which shall distinguish the Securities of the
                  series from Securities of any other series);

                           (2) the aggregate principal amount of such Securities
                  which may be authenticated and delivered under this Indenture,
                  which amount shall be specified therein and may be unlimited;

                                       26
<PAGE>

                           (3) the issue price and issuance date of such
                  Securities, including the date from which interest on such
                  Securities shall accrue;

                           (4) if applicable, that such Securities shall be
                  issuable in whole or in part in the form of one or more Global
                  Securities and, in such case, the respective depositories for
                  such Global Securities, the form of any legend or legends
                  which shall be borne by any such Global Security in addition
                  to or in lieu of that set forth in Exhibit 1 to Appendix A and
                  any circumstances in addition to or in lieu of those set forth
                  in Section 2.3 of Appendix A in which any such Global Security
                  may be exchanged in whole or in part for Securities
                  registered, and any transfer of such Global Security in whole
                  or in part may be registered, in the name or names of Persons
                  other than the depository for such Global Security or a
                  nominee thereof; and

                           (5) if applicable, that such Securities shall not be
                  issued in the form of Initial Securities subject to Appendix
                  A, but shall be issued in the form of Exchange Securities as
                  set forth in Exhibit A.

                  If any of the terms of any series are established by action
taken pursuant to a resolution of the Board of Directors, a copy of an
appropriate record of such action shall be certified by the Secretary or any
Assistant Secretary of the Company and delivered to the Trustee at or prior to
the delivery of the Officers' Certificate or the trust indenture supplementary
thereto setting forth the terms of the series. References in this Indenture to
Securities shall include any additional Securities issued after the Issue Date,
unless the context otherwise requires.

                  SECTION 2.02 Form and Dating. Provisions relating to the
Initial Securities of each series and the Exchange Securities are set forth in
Appendix A, which is hereby incorporated in and expressly made a part of this
Indenture. The Initial Securities of each series and the Trustee's certificate
of authentication shall be substantially in the form of Exhibit 1 to Appendix A
which is hereby incorporated in and expressly made a part of this Indenture. The
Exchange Securities and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A, which is hereby incorporated in and
expressly made a part of this Indenture. The Securities of each series may have
notations, legends or endorsements required by law, stock exchange rule,
agreements to which the Company is subject, if any, or usage, provided that any
such notation, legend or endorsement is in a form reasonably acceptable to the
Company. Each Security shall be dated the date of its authentication. The terms
of the Securities of each series set forth in Exhibit 1 to Appendix A and
Exhibit A are part of the terms of this Indenture.

                  SECTION 2.03 Execution and Authentication. Two Officers shall
sign the Securities for the Company by manual or facsimile signature. The
Company's seal shall be impressed, affixed, imprinted or reproduced on the
Securities and may be in facsimile form.

                  If an Officer whose signature is on a Security no longer holds
that office at the time the Trustee authenticates the Security, the Security
shall be valid nevertheless.

                  At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities of any series
executed by the Company to the

                                       27
<PAGE>

Trustee for authentication, together with a written order of the Company signed
by two Officers or by an Officer and either an Assistant Treasurer or an
Assistant Secretary of the Company for the authentication and delivery of such
Securities, and the Trustee in accordance with such written order of the Company
shall authenticate and deliver such Securities.

                  A Security shall not be valid until an authorized officer of
the Trustee manually signs the certificate of authentication on the Security.
The signature shall be conclusive evidence that the Security has been
authenticated under this Indenture.

                  The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate the Securities. Unless limited by the
terms of such appointment, an authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as any Registrar, Paying Agent or agent
for service of notices and demands.

                  SECTION 2.04 Registrar and Paying Agent. The Company shall
maintain an office or agency where Securities may be presented for registration
of transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent"). The Registrar
shall keep a register of the Securities and of their transfer and exchange. The
Company may have one or more co-registrars and one or more additional paying
agents. The term "Paying Agent" includes any additional paying agent.

                  The Company shall enter into an appropriate agency agreement
with any Registrar, Paying Agent or co-registrar not a party to this Indenture,
which shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the name and address of any such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any of its domestically incorporated Wholly Owned Subsidiaries may
act as Paying Agent, Registrar, co-registrar or transfer agent.

                  The Company initially appoints the Trustee as Registrar and
Paying Agent in connection with the Securities.

                  SECTION 2.05 Paying Agent To Hold Money in Trust. Prior to
each due date of the principal and interest on any Security, the Company shall
deposit with the Paying Agent a sum sufficient to pay such principal and
interest when so becoming due. The Company shall require each Paying Agent
(other than the Trustee) to agree in writing that the Paying Agent shall hold in
trust for the benefit of Securityholders or the Trustee all money held by the
Paying Agent for the payment of principal of or interest on the Securities and
shall notify the Trustee of any default by the Company in making any such
payment. If the Company or a Wholly Owned Subsidiary acts as Paying Agent, it
shall segregate the money held by it as Paying Agent and hold it as a separate
trust fund. The Company at any time may require a Paying Agent to pay all money
held by it to the Trustee and to account for any funds disbursed by the Paying
Agent. Upon complying with this Section, the Paying Agent shall have no further
liability for the money delivered to the Trustee.

                                       28
<PAGE>

                  SECTION 2.06 Securityholder Lists. The Trustee shall preserve
in as current a form as is reasonably practicable the most recent list available
to it of the names and addresses of Securityholders. If the Trustee is not the
Registrar, the Company shall furnish to the Trustee, in writing at least five
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Securityholders.

                  SECTION 2.07 Replacement Securities. If a mutilated Security
is surrendered to the Registrar or if the Holder of a Security claims that such
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies
any other reasonable requirements of the Trustee. If required by the Trustee or
the Company, such Holder shall furnish an indemnity bond sufficient in the
judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-registrar from any loss which any of them
may suffer if a Security is replaced. The Company and the Trustee may charge the
Holder for their expenses in replacing a Security.

                  Every replacement Security is an additional obligation of the
Company.

                  SECTION 2.08 Outstanding Securities. Securities outstanding at
any time are all Securities authenticated by the Trustee except for those
canceled by it, those delivered to it for cancellation and those described in
this Section as not outstanding. A Security does not cease to be outstanding
because the Company or an Affiliate of the Company holds the Security.

                  If a Security is replaced pursuant to Section 2.07, it ceases
to be outstanding unless the Trustee and the Company receive proof satisfactory
to them that the replaced Security is held by a bona fide purchaser.

                  If the Paying Agent segregates and holds in trust, in
accordance with this Indenture, on a redemption date or maturity date money
sufficient to pay all principal and interest payable on that date with respect
to the Securities (or portions thereof) to be redeemed or maturing, as the case
may be, and the Paying Agent is not prohibited from paying such money to the
Securityholders on that date pursuant to the terms of this Indenture, then on
and after that date such Securities (or portions thereof) cease to be
outstanding and interest on them ceases to accrue.

                  SECTION 2.09 Temporary Securities. Until definitive Securities
are ready for delivery, the Company may prepare and the Trustee shall
authenticate temporary Securities. Temporary Securities shall be substantially
in the form of definitive Securities but may have variations that the Company
considers appropriate for temporary Securities. Without unreasonable delay, the
Company shall prepare and the Trustee shall authenticate definitive Securities
and deliver them in exchange for temporary Securities.

                  SECTION 2.10 Cancelation. The Company at any time may deliver
Securities to the Trustee for cancelation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment.

                                       29
<PAGE>

The Trustee and no one else shall cancel and destroy (subject to the record
retention requirements of the Exchange Act) all Securities surrendered for
registration of transfer, exchange, payment or cancelation and shall, upon
written request, deliver a certificate of such destruction to the Company unless
the Company directs the Trustee to deliver canceled Securities to the Company.
The Company may not issue new Securities to replace Securities it has redeemed,
paid or delivered to the Trustee for cancelation.

                  SECTION 2.11 Defaulted Interest. If the Company defaults in a
payment of interest on the Securities, the Company shall pay defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner. The Company may pay the defaulted interest to the persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail to each
Securityholder a notice that states the special record date, the payment date
and the amount of defaulted interest to be paid.

                  SECTION 2.12 CUSIP Numbers. The Company in issuing the
Securities may use "CUSIP" numbers (if then generally in use) and, if so, the
Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to
Holders; provided, however, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers.

                                   ARTICLE 3

                                   Redemption

                  SECTION 3.01 Notices to Trustee. If the Company elects to
redeem Securities pursuant to paragraph 5 of the Securities, it shall notify the
Trustee in writing of the redemption date, the principal amount of Securities to
be redeemed and that such redemption is being made pursuant to paragraph 5 of
the Securities.

                  The Company shall give each notice to the Trustee provided for
in this Section at least 45 days before the redemption date unless the Trustee
consents to a shorter period. Such notice shall be accompanied by an Officers'
Certificate and an Opinion of Counsel from the Company to the effect that such
redemption will comply with the conditions herein.

                  SECTION 3.02 Selection of Securities To Be Redeemed. If less
than all the Securities are to be redeemed at any time, selection of Securities
for redemption may be made by the Trustee in compliance with the requirements of
the principal national securities exchange, if any, on which the Securities are
listed, or, if the Securities are not so listed, on a pro rata basis, by lot or
by such other method that the Trustee shall deem fair and appropriate. The
Trustee shall make the selection from outstanding Securities not previously
called for redemption. The Trustee may select for redemption portions of the
principal of Securities that have denominations larger than $1,000. Securities
and portions of them the Trustee selects shall be in amounts of $1,000 or a
whole multiple of $1,000. Provisions of this Indenture that apply to

                                       30
<PAGE>

Securities called for redemption also apply to portions of Securities called for
redemption. The Trustee shall notify the Company promptly of the Securities or
portions of Securities to be redeemed.

                  SECTION 3.03 Notice of Redemption. At least 30 days but not
more than 60 days before a date for redemption of Securities, the Company shall
mail a notice of redemption by first-class mail to each Holder of Securities to
be redeemed.

                  The notice shall identify the Securities to be redeemed and
shall state:

                           (1) the redemption date;

                           (2) the redemption price;

                           (3) the name and address of the Paying Agent;

                           (4) that Securities called for redemption must be
                  surrendered to the Paying Agent to collect the redemption
                  price;

                           (5) if fewer than all the outstanding Securities are
                  to be redeemed, the identification and principal amounts of
                  the particular Securities to be redeemed;

                           (6) that, unless the Company defaults in making such
                  redemption payment or the Paying Agent is prohibited from
                  making such payment pursuant to the terms of this Indenture,
                  interest on Securities (or portion thereof) called for
                  redemption ceases to accrue on and after the redemption date;
                  and

                           (7) that no representation is made as to the
                  correctness or accuracy of the CUSIP number, if any, listed in
                  such notice or printed on the Securities.

                  At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with the information required by this
Section.

                  SECTION 3.04 Effect of Notice of Redemption. Once notice of
redemption is mailed, Securities called for redemption become due and payable on
the redemption date and at the redemption price stated in the notice. Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest to the redemption date
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date that is on or prior
to the date of redemption). Failure to give notice or any defect in the notice
to any Holder shall not affect the validity of the notice to any other Holder.

                  SECTION 3.05 Deposit of Redemption Price. Prior to the
redemption date, the Company shall deposit with the Paying Agent (or, if the
Company or a Wholly Owned Subsidiary is the Paying Agent, shall segregate and
hold in trust) money sufficient to pay the redemption price of and accrued
interest (subject to the right of Holders of record on the relevant record date
to receive interest due on the relevant interest payment date that is on or
prior to the

                                       31
<PAGE>

date of redemption) on all Securities to be redeemed on that date other than
Securities or portions of Securities called for redemption which have been
delivered by the Company to the Trustee for cancelation.

                  SECTION 3.06 Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part, the Company shall execute and the Trustee
shall authenticate for the Holder (at the Company's expense) a new Security
equal in principal amount to the unredeemed portion of the Security surrendered.

                                   ARTICLE 4

                                   Covenants

                  SECTION 4.01 Payment of Securities. The Company shall promptly
pay the principal of and interest on the Securities on the dates and in the
manner provided in the Securities and in this Indenture. Principal and interest
shall be considered paid on the date due if on such date the Trustee or the
Paying Agent holds in accordance with this Indenture money sufficient to pay all
principal and interest then due and the Trustee or the Paying Agent, as the case
may be, is not prohibited from paying such money to the Securityholders on that
date pursuant to the terms of this Indenture.

                  The Company shall pay interest on overdue principal at the
rate specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

                  SECTION 4.02 SEC Reports. Notwithstanding that the Company may
not be required to remain subject to the reporting requirements of Section 13 or
15(d) of the Exchange Act, the Company shall file with the SEC and provide the
Trustee and Holders of Securities with the annual reports and the information,
documents and other reports which are specified in Sections 13 and 15(d) of the
Exchange Act, and, with respect to the annual consolidated financial statements
only, a report thereon by the Company's independent auditors; provided, however,
that the Company shall not be so obligated to file such information, documents
and reports with the SEC if the SEC does not permit such filings. The Company
also shall comply with the other provisions of Section 314(a) of the Trust
Indenture Act.

                  SECTION 4.03 Limitation on Indebtedness. The Company shall
not, and shall not permit any of its Restricted Subsidiaries to, directly or
indirectly, Incur any Indebtedness unless, after giving pro forma effect to the
Incurrence of such Indebtedness and the receipt and application of the proceeds
thereof, no Default or Event of Default would occur as a consequence of, or be
continuing following, such Incurrence and application and either (a) after
giving pro forma effect to such Incurrence and application, the Consolidated
Interest Coverage Ratio would exceed 2.5 to 1.0 or (b) such Indebtedness is
Permitted Indebtedness.

                  In the event that an item of Indebtedness (including
Indebtedness Incurred by the Company to banks or other lenders) could be
Incurred pursuant to more than one of the provisions of Permitted Indebtedness,
the Company, in its sole discretion, will classify or reclassify such item of
Indebtedness and only be required to include the amount and type of such

                                       32
<PAGE>

Indebtedness in (and to have Incurred such Indebtedness pursuant to) one of the
clauses of Permitted Indebtedness; and an item of Indebtedness (including
Indebtedness Incurred by the Company to banks or other lenders) may for this
purpose be divided into more than one of the types of Permitted Indebtedness.
Accrual of interest, accretion or amortization of original issue discount and
the payment of interest on any Indebtedness in the form of additional
Indebtedness with the same terms, will not be deemed to be an incurrence of
Indebtedness for purposes of this Section 4.03; provided, in each such case,
that the amount thereof is included in Consolidated Interest Expense of the
Company as accrued.

                  SECTION 4.04 Limitation on Restricted Payments. (a) The
Company shall not, and shall not permit any of its Restricted Subsidiaries to,
directly or indirectly, make any Restricted Payment if, at the time of and after
giving effect to the proposed Restricted Payment, (i) any Default or Event of
Default would have occurred and be continuing, (ii) the Company could not Incur
at least $1.00 of additional Indebtedness pursuant to clause (a) of Section 4.03
or (iii) the aggregate amount expended or declared for all Restricted Payments
from the Issue Date would exceed the sum (without duplication) of the following:

                  (A) 50% of the aggregate Consolidated Net Income of the
         Company accrued on a cumulative basis commencing on the last day of the
         fiscal quarter immediately preceding the Issue Date, and ending on the
         last day of the fiscal quarter ending on or immediately preceding the
         date of such proposed Restricted Payment (or, if such aggregate
         Consolidated Net Income shall be a loss, minus 100% of such loss), plus

                  (B) the aggregate net cash proceeds, or the Fair Market Value
         of Property other than cash, received by the Company on or after the
         Issue Date from the issuance or sale (other than to a Subsidiary of the
         Company) of Capital Stock of the Company or any options, warrants or
         rights to purchase Capital Stock of the Company, plus

                  (C) the aggregate net cash proceeds, or the Fair Market Value
         of Property other than cash, received by the Company as capital
         contributions to the Company (other than from a Subsidiary of the
         Company) on or after the Issue Date, plus

                  (D) the aggregate net cash proceeds received by the Company
         from the issuance or sale (other than to any Subsidiary of the Company)
         on or after the Issue Date of convertible Indebtedness that has been
         converted into or exchanged for Capital Stock of the Company, together
         with the aggregate cash received by the Company at the time of such
         conversion or exchange or received by the Company from any conversion
         or exchange of convertible Senior Indebtedness or convertible Pari
         Passu Indebtedness issued or sold (other than to any Subsidiary of the
         Company) prior to the Issue Date, plus

                  (E) to the extent not otherwise included in the Company's
         Consolidated Net Income, an amount equal to the net reduction in
         Investments made by the Company and its Restricted Subsidiaries
         subsequent to the Issue Date in any Person resulting from (1) payments
         of interest on debt, dividends, repayments of loans or advances or
         other transfers or distributions of Property, in each case to the
         Company or any Restricted Subsidiary from any Person other than the
         Company or a Restricted Subsidiary, and in an amount not to exceed the
         book value of such Investments previously made in such Person

                                       33
<PAGE>

         that were treated as Restricted Payments, or (2) the designation of any
         Unrestricted Subsidiary as a Restricted Subsidiary, and in an amount
         not to exceed the lesser of (x) the book value of all Investments
         previously made in such Unrestricted Subsidiary that were treated as
         Restricted Payments and (y) the Fair Market Value of such Unrestricted
         Subsidiary, plus

                  (F) $25,000,000.

                  (b) The limitations set forth in paragraph (a) above shall not
prevent the Company or any Restricted Subsidiary from making the following
Restricted Payments so long as, at the time thereof, no Default or Event of
Default shall have occurred and be continuing (except in the case of clause (i)
below under which the payment of a dividend is permitted):

                  (i) the payment of any dividend on Capital Stock or Redeemable
         Stock of the Company or any Restricted Subsidiary within 60 days after
         the declaration thereof, if at such declaration date such dividend
         could have been paid in compliance with paragraph (a) above;

                  (ii) the repurchase, redemption or other acquisition or
         retirement for value of any Capital Stock of the Company or any of its
         Subsidiaries held by any current or former officers, directors or
         employees of the Company or any of its Subsidiaries pursuant to the
         terms of agreements (including employment agreements) or plans approved
         by the Board of Directors, including any such repurchase, redemption,
         acquisition or retirement of shares of such Capital Stock that is
         deemed to occur upon the exercise of stock options or similar rights if
         such shares represent all or a portion of the exercise price or are
         surrendered in connection with satisfying Federal income tax
         obligations; provided, however, that the aggregate amount of such
         repurchases, redemptions, acquisitions and retirements shall not exceed
         the sum of (a) $1,000,000 in any twelve-month period and (b) the
         aggregate net proceeds, if any, received by the Company during such
         twelve-month period from any issuance of such Capital Stock pursuant to
         such agreements or plans;

                  (iii) the purchase, redemption or other acquisition or
         retirement for value of any Capital Stock or Redeemable Stock of the
         Company or any Restricted Subsidiary, in exchange for, or out of the
         aggregate net cash proceeds of, a substantially concurrent issuance and
         sale (other than to a Subsidiary of the Company or an employee stock
         ownership plan or trust established by the Company or any of its
         Subsidiaries, for the benefit of their employees) of Capital Stock of
         the Company;

                  (iv) the making of any principal payment on or the repurchase,
         redemption, legal defeasance or other acquisition or retirement for
         value, prior to any scheduled principal payment, scheduled sinking fund
         payment or maturity, of any Subordinated Indebtedness (other than
         Redeemable Stock) in exchange for, or out of the aggregate net cash
         proceeds of, a substantially concurrent issuance and sale (other than
         to a Subsidiary of the Company or an employee stock ownership plan or
         trust established by the Company or any of its Subsidiaries, for the
         benefit of their employees) of Capital Stock of the Company;

                                       34
<PAGE>

                  (v) the making of any principal payment on or the repurchase,
         redemption, legal defeasance or other acquisition or retirement for
         value of Subordinated Indebtedness in exchange for, or out of the
         aggregate net cash proceeds of a substantially concurrent Incurrence
         (other than a sale to a Subsidiary of the Company) of Subordinated
         Indebtedness so long as such new Indebtedness is Permitted Refinancing
         Indebtedness and (A) has an Average Life that is longer than the
         Average Life of the Securities and (B) has a Stated Maturity for its
         final scheduled principal payment that is more than one year after the
         Stated Maturity of the final scheduled principal payment of the
         Securities; and

                  (vi) loans made to officers, directors or employees of the
         Company or any Restricted Subsidiary approved by the Board of Directors
         (or a duly authorized officer), the net cash proceeds of which are used
         solely (A) to purchase common stock of the Company in connection with a
         restricted stock or employee stock purchase plan, or to exercise stock
         options received pursuant to an employee or director stock option plan
         or other incentive plan, in a principal amount not to exceed the
         exercise price of such stock options or (B) to refinance loans,
         together with accrued interest thereon, made pursuant to item (A) of
         this clause (vi).

The actions described in clauses (i) and (ii) of this paragraph (b) shall be
included in the calculation of the amount of Restricted Payments. The actions
described in clauses (iii), (iv), (v) and (vi) of this paragraph (b) shall be
excluded in the calculation of the amount of Restricted Payments, provided that
the net cash proceeds from any issuance or sale of Capital Stock of the Company
pursuant to such clause (iii), (iv) or (vi) shall be excluded from any
calculations pursuant to clause (B) or (C) under the immediately preceding
paragraph (a).

                  (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.

                  SECTION 4.05 Limitation on Restrictions on Distributions from
Restricted Subsidiaries. The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
permit to exist or become effective any consensual encumbrance or restriction on
the legal right of any Restricted Subsidiary to (i) pay dividends, in cash or
otherwise, or make any other distributions on or in respect of its Capital Stock
or Redeemable Stock, or pay any Indebtedness or other obligation owed, to the
Company or any other Restricted Subsidiary, (ii) make loans or advances to the
Company or any other Restricted Subsidiary or (iii) transfer any of its Property
to the Company or any other Restricted Subsidiary. Such limitation shall not
apply (a) with respect to clauses (i), (ii) and (iii), to

                                       35
<PAGE>

encumbrances and restrictions (1) in the Bank Credit Facilities and other
agreements and instruments, in each case as in effect on the Issue Date, (2)
relating to Indebtedness of a Restricted Subsidiary and existing at the time it
became a Restricted Subsidiary if such encumbrance or restriction was not
created in anticipation of or in connection with the transactions pursuant to
which such Restricted Subsidiary became a Restricted Subsidiary or (3) which
result from the renewal, refinancing, extension or amendment of an agreement
that is the subject of clause (a)(1) or (2) above or clause (b)(1) or (2) below,
provided that such encumbrance or restriction is not materially less favorable
to the Holders of Securities than those under or pursuant to the agreement so
renewed, refinanced, extended or amended, and (b) with respect to clause (iii)
only, to (1) any restriction on the sale, transfer or other disposition of
Property relating to Indebtedness that is permitted to be Incurred and secured
under Sections 4.03 and 4.10, (2) any encumbrance or restriction applicable to
Property at the time it is acquired by the Company or a Restricted Subsidiary,
so long as such encumbrance or restriction relates solely to the Property so
acquired and was not created in anticipation of or in connection with such
acquisition, (3) customary provisions restricting subletting or assignment of
leases and customary provisions in other agreements that restrict assignment of
such agreements or rights thereunder and (4) customary restrictions contained in
asset sale agreements limiting the transfer of such assets pending the closing
of such sale.

                  SECTION 4.06 Limitation on Asset Sales. (a) The Company shall
not, and shall not permit any Restricted Subsidiary to, consummate 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 Property subject to such Asset Sale and (ii) all of the
consideration paid to the Company or such Restricted Subsidiary in connection
with such Asset Sale is in the form of cash, cash equivalents, Liquid
Securities, Exchanged Properties or the assumption by the purchaser of
liabilities of the Company (other than liabilities of the Company that are by
their terms subordinated to the Securities) or liabilities of any Restricted
Subsidiary that made such Asset Sale (other than liabilities of a Subsidiary
Guarantor that are by their terms subordinated to such Subsidiary Guarantor's
Subsidiary Guaranty), in each case as a result of which the Company and its
remaining Restricted Subsidiaries are no longer liable for such liabilities
("Permitted Consideration"); provided, however, that the Company and its
Restricted Subsidiaries shall be permitted to receive Property other than
Permitted Consideration, so long as the aggregate Fair Market Value of all 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.

                  The Net Available Cash from Asset Sales by the Company or a
Restricted Subsidiary may be applied by the Company, such Restricted Subsidiary
or another Restricted Subsidiary, to the extent the Company or such Restricted
Subsidiary elects (or is required by the terms of any Senior Indebtedness of the
Company or a Subsidiary Guarantor), to (i) prepay, repay or purchase Senior
Indebtedness of the Company or a Subsidiary Guarantor or any Indebtedness of a
Restricted Subsidiary that is not a Subsidiary Guarantor (in each case excluding
Indebtedness owed to the Company or an Affiliate of the Company), (ii) reinvest
in Additional Assets (including by means of an Investment in Additional Assets
by a Restricted Subsidiary with Net Available Cash received by the Company or
another Restricted Subsidiary) or (iii) purchase Securities or purchase both
Securities and one or more series or issues of other

                                       36
<PAGE>

Pari Passu Indebtedness on a pro rata basis (excluding Securities and Pari Passu
Indebtedness owned by the Company or an Affiliate of the Company). Pending any
reinvestment pursuant to clause (ii) above, the Company may temporarily prepay,
repay or purchase Senior Indebtedness of the Company or a Subsidiary Guarantor.

                  (b) Any Net Available Cash from an Asset Sale not applied in
accordance with the preceding paragraph within 365 days from the date of such
Asset Sale shall constitute "Excess Proceeds." When the aggregate amount of
Excess Proceeds exceeds $20,000,000, the Company shall be required to make an
offer to purchase Securities having an aggregate principal amount equal to the
aggregate amount of Excess Proceeds (the "Prepayment Offer") at a purchase price
equal to 100% of the principal amount of such Securities plus accrued and unpaid
interest, if any, to the Purchase Date (as defined) in accordance with the
procedures (including prorating in the event of oversubscription) set forth
herein, but, if the terms of any Pari Passu Indebtedness require that a Pari
Passu Offer be made contemporaneously with the Prepayment Offer, then the Excess
Proceeds shall be prorated between the Prepayment Offer and such Pari Passu
Offer in accordance with the aggregate outstanding principal amounts of the
Securities and such Pari Passu Indebtedness, and the aggregate principal amount
of Securities for which the Prepayment Offer is made shall be reduced
accordingly. If the aggregate principal amount of Securities tendered by Holders
thereof exceeds the amount of available Excess Proceeds, then such Excess
Proceeds shall be allocated pro rata according to the principal amount of the
Securities tendered and the Trustee shall select the Securities to be purchased
in accordance herewith. To the extent that any portion of the amount of Excess
Proceeds remains after compliance with the second sentence of this paragraph and
provided that all Holders of Securities have been given the opportunity to
tender their Securities for purchase as described in the following paragraph in
accordance with this Indenture, the Company and its Restricted Subsidiaries may
use such remaining amount for purposes permitted by this Indenture and the
amount of Excess Proceeds shall be reset to zero.

                  (c) (1) Within 30 days after the 365th day following the date
of an Asset Sale, the Company shall, if it is obligated to make an offer to
purchase the Securities pursuant to the preceding paragraph, send a written
Prepayment Offer notice, by first-class mail, to the Trustee and the Holders of
the Securities (the "Prepayment Offer Notice"), accompanied by such information
regarding the Company and its Subsidiaries as the Company believes shall enable
such Holders of the Securities to make an informed decision with respect to the
Prepayment Offer (which at a minimum shall include (i) the most recently filed
Annual Report on Form 10-K (including audited consolidated financial statements)
of the Company, the most recent subsequently filed Quarterly Report on Form 10-Q
of the Company and any Current Report on Form 8-K of the Company filed
subsequent to such Quarterly Report, other than Current Reports describing Asset
Sales otherwise described in the offering materials, or corresponding successor
reports (or, during any time that the Company is not subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, corresponding reports
prepared pursuant to Section 4.02), (ii) a description of material developments
in the Company's business subsequent to the date of the latest of such reports
and (iii) if material, appropriate pro forma financial information). The
Prepayment Offer Notice shall state, among other things, (i) that the Company is
offering to purchase Securities pursuant to the provisions of this Indenture,
(ii) that any Security (or any portion thereof) accepted for payment (and duly
paid on the Purchase Date) pursuant to the Prepayment Offer shall cease to
accrue interest on the Purchase Date, (iii) that

                                       37
<PAGE>

any Securities (or portions thereof) not properly tendered shall continue to
accrue interest, (iv) the purchase price and purchase date, which shall be,
subject to any contrary requirements of applicable law, no less than 30 days nor
more than 60 days after the date the Prepayment Offer Notice is mailed (the
"Purchase Date"), (v) the aggregate principal amount of Securities to be
purchased, (vi) a description of the procedure which Holders of Securities must
follow in order to tender their Securities and the procedures that Holders of
Securities must follow in order to withdraw an election to tender their
Securities for payment and (vii) all other instructions and materials necessary
to enable Holders to tender Securities pursuant to the Prepayment Offer.

                  (2) Not later than the date upon which written notice of a
Prepayment Offer is delivered to the Trustee as provided above, the Company
shall deliver to the Trustee an Officers' Certificate as to (i) the amount of
the Prepayment Offer (the "Offer Amount"), (ii) the allocation of the Net
Available Cash from the Asset Sales pursuant to which such Prepayment Offer is
being made and (iii) the compliance of such allocation with the provisions of
Section 4.06(a). On such date, the Company shall also irrevocably deposit with
the Trustee or with the Paying Agent (or, if the Company or a Wholly Owned
Subsidiary is the Paying Agent, shall segregate and hold in trust) in Permitted
Short-Term Investments, maturing on the last day prior to the Purchase Date or
on the Purchase Date if funds are immediately available by open of business, an
amount equal to the Offer Amount to be held for payment in accordance with the
provisions of this Section. Upon the expiration of the period for which the
Prepayment Offer remains open (the "Offer Period"), the Company shall deliver to
the Trustee for cancelation the Securities or portions thereof which have been
properly tendered to and are to be accepted by the Company. The Trustee or the
Paying Agent shall, on the Purchase Date, mail or deliver payment to each
tendering Holder in the amount of the purchase price. In the event that the
aggregate purchase price of the Securities delivered by the Company to the
Trustee is less than the Offer Amount, the Trustee or the Paying Agent shall
deliver the excess to the Company immediately after the expiration of the Offer
Period for application in accordance with this Section.

                  (3) Holders electing to have a Security purchased shall be
required to surrender the Security, with an appropriate form duly completed, to
the Company or its agent at the address specified in the notice at least three
Business Days prior to the Purchase Date. Holders shall be entitled to withdraw
their election if the Trustee or the Company receives not later than one
Business Day prior to the Purchase Date, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Security which was delivered for purchase by the Holder and a
statement that such Holder is withdrawing his election to have such Security
purchased. If at the expiration of the Offer Period the aggregate principal
amount of Securities surrendered by Holders exceeds the Offer Amount, the
Company shall select the Securities to be purchased on a pro rata basis (with
such adjustments as may be deemed appropriate by the Company so that only
Securities in denominations of $1,000, or integral multiples thereof, shall be
purchased). Holders whose Securities are purchased only in part shall be issued
new Securities equal in principal amount to the unpurchased portion of the
Securities surrendered.

                  (4) At the time the Company delivers Securities to the Trustee
which are to be accepted for purchase, the Company shall also deliver an
Officers' Certificate stating that such Securities are to be accepted by the
Company pursuant to and in accordance with the terms of

                                       38
<PAGE>

this Section 4.06. A Security shall be deemed to have been accepted for purchase
at the time the Trustee or the Paying Agent mails or delivers payment therefor
to the surrendering Holder.

                  (d) The Company shall comply, to the extent applicable, with
the requirements of Rule 14e-1 under the Exchange Act and any other securities
laws or regulations thereunder to the extent such laws and regulations are
applicable in connection with the purchase of Securities as described above. To
the extent that the provisions of any securities laws or regulations conflict
with the provisions relating to the Prepayment Offer, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations described above by virtue thereof.

                  SECTION 4.07 Limitation on Transactions with Affiliates. (a)
The Company shall not, and shall not permit any of its Restricted Subsidiaries
to, directly or indirectly, conduct any business or enter into any transaction
or series of transactions (including the sale, transfer, disposition, purchase,
exchange or lease of Property, the making of any Investment, the giving of any
Guarantee or the rendering of any service) with or for the benefit of any
Affiliate of the Company (other than the Company or a Restricted Subsidiary),
unless (i) such transaction or series of transactions is on terms no less
favorable to the Company or such Restricted Subsidiary than those that could be
obtained in a comparable arm's-length transaction with a Person that is not an
Affiliate of the Company or such Restricted Subsidiary, and (ii) with respect to
a transaction or series of transactions involving aggregate payments by or to
the Company or such Restricted Subsidiary having a Fair Market Value equal to or
in excess of (a) $5,000,000 but less than $10,000,000, an Officer certifies that
such transaction or series of transactions complies with clause (i) of this
paragraph, as evidenced by an Officer's Certificate delivered to the Trustee or
(b) $10,000,000, the Board of Directors (including a majority of the
disinterested members of such Board of Directors) approves such transaction or
series of transactions and certifies that such transaction or series of
transactions complies with clause (i) of this paragraph, as evidenced by a
certified resolution delivered to the Trustee.

                  The limitations of the preceding paragraph do not apply to (i)
the payment of reasonable and customary regular fees to directors of the Company
or any of its Restricted Subsidiaries who are not employees of the Company or
any of its Restricted Subsidiaries, (ii) indemnities of officers and directors
of the Company or any Subsidiary consistent with such Person's charter, bylaws
and applicable statutory provisions, (iii) any issuance of securities, or other
payments, awards or grants in cash, securities or otherwise pursuant to, or the
funding of, employment arrangements, stock options and stock ownership plans
approved by the Board of Directors, (iv) loans made (a) to officers, directors
or employees of the Company or any Restricted Subsidiary approved by the Board
of Directors (or by a duly authorized Officer), the proceeds of which are used
solely to purchase common stock of the Company in connection with a restricted
stock or employee stock purchase plan, or to exercise stock options received
pursuant to an employee or director stock option plan or other incentive plan,
in a principal amount not to exceed the exercise price of such stock options, or
(b) to refinance loans, together with accrued interest thereon, made pursuant to
this clause (iv), (v) advances and loans to officers, directors and employees of
the Company or any Subsidiary, provided such loans and advances (excluding loans
or advances made pursuant to the preceding clause (iv)) do not exceed $5,000,000
at any one time outstanding, (vi) any Restricted Payment permitted to be paid
pursuant to Section 4.04, (vii) any transaction or series of transactions
between the Company and one or more Restricted

                                       39
<PAGE>

Subsidiaries or between two or more Restricted Subsidiaries in the ordinary
course of business, provided that no more than 10% of the total voting power of
the Voting Stock of any such Restricted Subsidiary is owned by an Affiliate of
the Company (other than a Restricted Subsidiary) and (viii) any transaction or
series of transactions pursuant to any agreement or obligation of the Company or
any of its Restricted Subsidiaries in effect on the Issue Date.

                  SECTION 4.08 [Intentionally Omitted]

                  SECTION 4.09 Change of Control. (a) Upon the occurrence of a
Change of Control, each Holder of Securities shall have the right to require the
Company to repurchase all or any part (equal to $1,000 in principal amount or an
integral multiple thereof) of such Holder's Securities pursuant to the offer
described below (the "Change of Control Offer") at a purchase price in cash
equal to 101% of the principal amount thereof, plus accrued and unpaid interest,
if any, to the date of purchase, subject to the right of Holders of record on
the relevant record date to receive interest due on the relevant interest
payment date (the "Change of Control Payment").

                  (b) Within 30 days following any Change of Control or, at the
Company's option, prior to such Change of Control but after the public
announcement thereof, the Company shall mail a notice to each Holder stating,
among other things: (i) that a Change of Control has occurred or is expected to
occur, as applicable, and a Change of Control Offer is being made pursuant to
this Indenture and that all Securities (or portions thereof) properly tendered
shall be accepted for payment; (ii) the purchase price and the purchase date,
which shall be, subject to any contrary requirements of applicable law, no fewer
than 30 days nor more than 60 days from the date the Company mails such notice
and which may not be prior to the Change of Control (the "Change of Control
Payment Date"); (iii) that any Security (or portion thereof) accepted for

to enable Holders to tender Securities pursuant to the Change of Control Offer.

                  (c) Holders electing to have a Security purchased shall be
required to surrender the Security, with an appropriate form duly completed, to
the Company or its agent at the address specified in the notice at least three
Business Days prior to the Change of Control Payment Date. Holders shall be
entitled to withdraw their election if the Trustee or the Company receives not
later than one Business Day prior to the Change of Control Payment Date, a
telegram, telex, facsimile transmission or letter setting forth the name of the
Holder, the principal amount of the Security which was delivered for purchase by
the Holder and a statement that such Holder is withdrawing his election to have

<PAGE>

                  (d) On or prior to the Change of Control Payment Date, the
Company shall irrevocably deposit with the Trustee or with the Paying Agent (or,
if the Company or any of its Wholly Owned Subsidiaries is acting as the Paying
Agent, segregate and hold in trust) in cash an amount equal to the Change of
Control Payment payable to the Holders entitled thereto, to be held for payment
in accordance with the provisions of this Section.

                  (e) On the Change of Control Payment Date, the Company shall
deliver to the Trustee the Securities or portions thereof which have been
properly tendered to and are to be accepted by the Company for payment. The
Trustee or the Paying Agent shall, on the Change of Control Payment Date, mail
or deliver payment to each tendering Holder of the Change of Control Payment. In
the event that the aggregate Change of Control Payment is less than the amount
delivered by the Company to the Trustee or the Paying Agent, the Trustee or the
Paying Agent, as the case may be, shall deliver the excess to the Company
immediately after the Change of Control Payment Date.

                  (f) The Company shall not be required to make a Change of
Control Offer upon a Change of Control if a third party makes the Change of
Control Offer in the manner, at the times and otherwise in compliance with the
requirements set forth in this Indenture 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.

                  (g) The Company shall comply, to the extent applicable, with
the requirements of Rule 14e-1 under the Exchange Act and any other securities
laws or regulations thereunder to the extent such laws and regulations are
applicable in connection with the purchase of Securities pursuant to this
Section. To the extent that the provisions of any securities laws or regulations
conflict with provisions of this Section, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Section by virtue thereof.

                  SECTION 4.10 Limitation on Liens. The Company shall not, and
shall not permit any Restricted Subsidiary to, directly or indirectly, enter
into, create, Incur, assume or suffer to exist any Lien on or with respect to
any Property of the Company or such Restricted Subsidiary, whether owned on the
Issue Date or acquired after the Issue Date, or any interest therein or any
income or profits therefrom, unless the Securities or any Subsidiary Guaranty of
such Restricted Subsidiary, as applicable, are secured equally and ratably with
(or prior to) any and all other obligations secured by such Lien, except that
the Company and its Restricted Subsidiaries may enter into, create, Incur,
assume or suffer to exist Liens securing Senior Indebtedness and Permitted
Liens.

                  SECTION 4.11 Compliance Certificate. The Company shall deliver
to the Trustee within 120 days after the end of each fiscal year of the Company
an Officers' Certificate stating that in the course of the performance by the
signers of their duties as Officers of the Company they would normally have
knowledge of any Default and whether or not the signers know of any Default that
occurred during such period. If they do, the certificate shall describe the
Default, its status and what action the Company is taking or proposes to take
with respect thereto. The Company also shall comply with TIA Section 314(a)(4).

                  SECTION 4.12 Further Instruments and Acts. Upon request of the
Trustee, the Company shall execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more
effectively the purpose of this Indenture.

                  SECTION 4.13 Future Subsidiary Guarantors. The Company shall
cause each Restricted Subsidiary that (i) Incurs Indebtedness or issues
Preferred Stock following the Issue Date or (ii) has Indebtedness or Preferred
Stock outstanding on the date on which such Restricted Subsidiary becomes a
Restricted Subsidiary, to execute and deliver to the Trustee a Subsidiary
Guaranty at the time such Restricted Subsidiary Incurs such Indebtedness or
becomes a Restricted Subsidiary and a supplemental indenture in the form of
Exhibit B pursuant to which such Subsidiary shall guaranty payment of the
Securities as provided in Section 11.06; provided, however, that such Restricted
Subsidiary shall not be required to deliver a Subsidiary Guaranty if the
aggregate amount of such Indebtedness or Preferred Stock, together with all
other Indebtedness and Preferred Stock then outstanding (a) of such Restricted
Subsidiary, is less than $10,000,000 and (b) among Restricted Subsidiaries that
are not Subsidiary Guarantors is less than $25,000,000.

                  SECTION 4.14 Incurrence of Layered Indebtedness. (i) The
Company shall not Incur any Indebtedness which is subordinated or junior in
right of payment to any Senior Indebtedness of the Company unless such
Indebtedness constitutes Indebtedness which is junior to, or pari passu with,
the Securities in right of payment and (ii) no Subsidiary Guarantor shall Incur
any Indebtedness that is subordinated or junior in right of payment to any
Senior Indebtedness of such Subsidiary Guarantor unless such Indebtedness
constitutes Indebtedness which is junior to, or pari passu with, such Subsidiary
Guarantor's Subsidiary Guaranty in right of payment.

                  SECTION 4.15 Restricted and Unrestricted Subsidiaries. Unless
defined or designated as an Unrestricted Subsidiary, any Person that becomes a
Subsidiary of the Company or any of its Restricted Subsidiaries shall be
classified as a Restricted Subsidiary subject to the provisions of the next
paragraph. The Company may designate a Subsidiary (including a newly formed or
newly acquired Subsidiary) of the Company or any of its Restricted Subsidiaries
as an Unrestricted Subsidiary if (i) such Subsidiary does not at such time own
any Capital Stock or Indebtedness of, or own or hold any Lien on any Property
of, the Company or any other Restricted Subsidiary, (ii) such Subsidiary does
not at such time have any Indebtedness or other obligations which, if in
default, would result (with the passage of time or notice or otherwise) in a
default on any Indebtedness of the Company or any Restricted Subsidiary and
(iii)(a) such designation is effective immediately upon such Subsidiary becoming
a Subsidiary of the Company or of a Restricted Subsidiary, (b) the Subsidiary to
be so designated has total assets of $1,000 or less or (c) if such Subsidiary
has assets greater than $1,000, then such redesignation as an Unrestricted
Subsidiary is deemed to constitute a Restricted Payment in an amount equal to
the Fair Market Value of the Company's direct and indirect ownership interest in
such Subsidiary, and such Restricted Payment would be permitted to be made at
the time of such designation under Section 4.04. Except as provided in the
immediately preceding sentence, no Restricted Subsidiary may be redesignated as
an Unrestricted Subsidiary. The designation of an Unrestricted Subsidiary or
removal of such designation shall be made by the Board of Directors pursuant to
a certified resolution delivered to the Trustee and shall be effective as of the
date specified in the applicable certified resolution, which shall not be prior
to the date such certified

                                       42
<PAGE>

resolution is delivered to the Trustee. Upon designation of a Restricted
Subsidiary as an Unrestricted Subsidiary in compliance with this Section, such
Restricted Subsidiary shall, by delivery of a supplemental indenture in form
satisfactory to the Trustee, be released from any Subsidiary Guaranty previously
made by such Subsidiary.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, take any action or enter into any transaction or
series of transactions that would result in a Person becoming a Restricted
Subsidiary (whether through an acquisition or otherwise) unless, after giving
effect to such action, transaction or series of transactions, on a pro forma
basis, (i) the Company could Incur at least $1.00 of additional Indebtedness
pursuant to clause (a) of Section 4.03 and (ii) no Default or Event of Default
would occur or be continuing.

                  SECTION 4.16 Suspension of Certain Covenants. In the event of
the occurrence of a Fall Away Event, (a) the covenants and provisions contained
hereunder under Section 4.03, Section 4.04, Section 4.05, Section 4.06, Section
4.07 and Section 4.13 shall each no longer be in effect for the remaining term
of the Notes, subject to the following paragraph, and (b) the Company will no
longer be subject to the financial test set forth in clause (iv) of Section
5.01(i).

                  If, at any time after the occurrence of a Fall Away Event, the
Company fails to maintain Investment Grade status, then the covenants which are
no longer in effect pursuant to the preceding paragraph shall thereafter be
reinstated and be applicable to the Company and its Restricted Subsidiaries
pursuant to the terms of the Indenture unless and until a subsequent Fall Away
Event occurs; provided, however, that no Default, Event of Default or breach of
any kind shall be deemed to exist under the Indenture based on, and none of the
Company or any of its Subsidiaries shall bear any liability for, any actions
taken or events occurring after the occurrence of a Fall Away Event and before
any reinstatement of such covenants as provided above, or any actions taken at
any time pursuant to any contractual obligation arising prior to such
reinstatement, regardless of whether such actions or events would have been
permitted if the applicable covenants remained in effect during such period.

                                Successor Company

                  SECTION 5.01 When Company May Merge or Transfer Assets. The
Company shall not consolidate with or merge with or into any Person, or convey,
transfer or lease, in one transaction or a series of transactions, all or
substantially all the property of the Company and its Restricted Subsidiaries,
taken as a whole, unless:

                  (i) the resulting, surviving or transferee Person (the
         "Successor Company") shall be a Person organized or existing under the
         laws of the United States of America, any State thereof or the District
         of Columbia and the Successor Company (if not the Company) shall
         expressly assume, by a supplemental indenture, executed and delivered
         to the Trustee, in form satisfactory to the Trustee, all the
         obligations of the Company under the Securities and this Indenture;
         (ii) in the case of a conveyance, transfer or lease of all or
         substantially all the Property of the Company and its Restricted
         Subsidiaries,

                                       43
<PAGE>

         taken as a whole, such Property shall have been so conveyed,
         transferred or leased as an entirety or virtually as an entirety to one
         Person; (iii) immediately after giving effect to such transaction (and
         treating, for purposes of this clause (iii) and clause (iv) below, any
         Indebtedness which becomes or is anticipated to become an obligation of
         the Successor Company or any Restricted Subsidiary as a result of such
         transaction as having been Incurred by such Successor Company or such
         Restricted Subsidiary at the time of such transaction), no Default or
         Event of Default shall have occurred and be continuing; (iv) other than
         with respect to the consolidation of the Company with or merger of the
         Company with or into, or the conveyance, transfer or lease of all or
         substantially all of the Property of the Company and its Restricted
         Subsidiaries, taken as a whole, to a Wholly Owned Subsidiary,
         immediately after giving effect to such transactions, the Successor
         Company would be able to Incur an additional $1.00 of Indebtedness
         pursuant to clause (a) of Section 4.03; and (v) the Company shall have
         delivered to the Trustee an Officer's Certificate, stating that such
         consolidation, merger or transfer and such supplemental indenture (if
         any) comply with this Indenture. The provisions of clauses (i), (ii),
         (iii), (iv) and (v) above shall not apply to any transactions which
         constitute an Asset Sale if the Company has complied with Section 4.06.

                  The Successor Company shall be the successor to the Company
and shall succeed to, and be substituted for, and may exercise every right and
power of, the Company under this Indenture, but the predecessor Company in the
case of a conveyance, transfer or lease shall not be released from the
obligation to pay the principal of and interest on the Securities.

                  SECTION 5.02 When a Subsidiary Guarantor May Merge or Transfer
Assets. The Company shall not permit any Subsidiary Guarantor to consolidate
with or merge with or into, or convey, transfer or lease, in one transaction or
series of transactions, all or substantially all of its Property to, any Person
(other than the Company or any other Subsidiary Guarantor) unless:

                  (a) the Successor Company (if not such Subsidiary) shall be a
         person organized and existing under the laws of the United States of
         America, any State thereof or the District of Columbia and the
         Successor Company (if not such Subsidiary) shall expressly assume, by a
         supplemental indenture, in form satisfactory to the Trustee, all the
         obligations of such Subsidiary under its Subsidiary Guaranty; (b) in
         the case of a conveyance, transfer or lease of all or substantially all
         the Property of such Subsidiary Guarantor, such Property shall have
         been so conveyed, transferred or leased as an entirety or virtually as
         an entirety to one Person; (c) immediately after giving effect to such
         transaction no Default or Event of Default shall have occurred and be
         continuing and (d) the Company shall have delivered to the Trustee an
         Officers' Certificate, stating that such consolidation, merger or
         transfer and such supplemental indenture (if any) comply with this
         Indenture. The provisions of clauses (a), (b), (c) and (d) above shall
         not apply to any transactions which constitute an Asset Sale if the
         Company has complied with Section 4.06.

                  The Successor Company shall be the successor to the applicable
Subsidiary Guarantor and shall succeed to, and be substituted for, and may
exercise every right and power of such Subsidiary Guarantor under its Subsidiary
Guaranty, but the predecessor Subsidiary

                                       44
<PAGE>

Guarantor in the case of a conveyance, transfer or lease shall not be released
from the obligation to pay the principal of and interest on the Securities.

                                   ARTICLE 6

                              Defaults and Remedies

                  SECTION 6.01 Events of Default. The following events shall be
"Events of Default":

                  (1) the Company defaults in any payment of interest on any
         Security when the same becomes due and payable, whether or not such
         payment shall be prohibited by Article 10, and such default continues
         for a period of 30 days;

                  (2) the Company defaults in the payment of the principal of
         any Security when the same becomes due and payable at its Stated
         Maturity, upon optional redemption, upon required repurchase, upon
         declaration or otherwise, whether or not such payment shall be
         prohibited by Article 10;

                  (3) the Company or any Subsidiary Guarantor fails to comply
         with Article 5;

                  (4) default in the performance, or breach, of any covenant or
         warranty of the Company or any Subsidiary Guarantor in this Indenture
         (other than a covenant or warranty addressed in clauses (1), (2) or (3)
         above) and continuance of such default or breach for a period of 60
         days after the notice specified below;

                  (5) default by the Company or any Restricted Subsidiary under
         any Indebtedness for borrowed money (other than Non-recourse Purchase
         Money Indebtedness) of the Company or any Restricted Subsidiary which
         results in acceleration of the maturity of such Indebtedness, or the
         failure to pay such Indebtedness at maturity, in an amount greater than
         $10,000,000 or its foreign currency equivalent at the time if such
         Indebtedness is not discharged or such acceleration is not rescinded or
         annulled within 10 days after the notice specified below;

                  (6) the Company or any Significant Subsidiary pursuant to or
         within the meaning of any Bankruptcy Law:

                  (A) commences a voluntary case;

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

                  (C) consents to the appointment of a Custodian of it or for
                  any substantial part of its property; or

                  (D) makes a general assignment for the benefit of its
                  creditors; or takes any comparable action under any foreign
                  laws relating to insolvency;

                                       45
<PAGE>

                  (7) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that:

                  (A) is for relief against the Company or any Significant
                  Subsidiary in an involuntary case;

                  (B) appoints a Custodian of the Company or any Significant
                  Subsidiary or for any substantial part of its property;

                  (C) orders the winding up or liquidation of the Company or any
                  Significant Subsidiary; or

                  (D) grants any similar relief under any foreign laws; and in
                  each such case the order or decree remains unstayed and in
                  effect for 60 days;

                  (8) one or more final judgments or orders by a court of
         competent jurisdiction are entered against the Company or any
         Restricted Subsidiary in an uninsured or unindemnified aggregate amount
         outstanding at any time in excess of $10,000,000 and such judgments or
         orders are not discharged, waived, stayed, satisfied or bonded for a
         period of 60 consecutive days; or

                  (9) a Subsidiary Guaranty ceases to be in full force and
         effect (other than in accordance with the terms of this Indenture and
         such Subsidiary Guaranty) or a Subsidiary Guarantor denies or
         disaffirms its obligations under its Subsidiary Guaranty.

                  The foregoing shall constitute Events of Default whatever the
reason for any such Event of Default and whether it is voluntary or involuntary
or is effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or
governmental body.

                  The term "Bankruptcy Law" means Title 11, United States Code,
or any similar Federal or state law for the relief of debtors. The term
"Custodian" means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law.

                  A Default under clause (4) or (5) is not an Event of Default
until the Trustee or the Holders of at least 25% in aggregate principal amount
of the outstanding Securities notify the Company (and in the case of such notice
by Holders, the Trustee) in writing of such Default and the Company does not
cure such Default within the time specified after receipt of such notice. Such
notice must specify the Default, demand that it be remedied and state that such
notice is a "Notice of Default."

                  The Company shall deliver to the Trustee, within 30 days after
the occurrence thereof, written notice in the form of an Officers' Certificate
of any Event of Default and any event which with the giving of notice or the
lapse of time would become an Event of Default, its status and what action the
Company is taking or proposes to take with respect thereto.

                  SECTION 6.02 Acceleration. If an Event of Default (other than
an Event of Default specified in Section 6.01(6) or (7)) occurs and is
continuing, the Trustee by notice to

                                       46
<PAGE>

the Company, or the Holders of at least 25% in aggregate principal amount of the
Securities by notice to the Company and the Trustee, may declare the principal
of the Securities to be due and payable. Upon such a declaration, such principal
shall be due and payable immediately. If an Event of Default specified in
Section 6.01(6) or (7) occurs, the principal of the Securities shall
automatically and without any action by the Trustee or any Holder, become
immediately due and payable. The Holders of a majority in aggregate principal
amount of the outstanding Securities by notice to the Trustee and the Company
may rescind any declaration of acceleration if the rescission would not conflict
with any judgment or decree, and if all existing Events of Default have been
cured or waived except nonpayment of principal or interest that has become due
solely because of the acceleration. No such rescission shall affect any
subsequent Default or impair any right consequent thereto.

                  SECTION 6.03 Other Remedies. If an Event of Default occurs and
is continuing, the Trustee may pursue any available remedy to collect the
payment of principal of or interest on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.

                  The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Securityholder in exercising any right
or remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

                  SECTION 6.04 Waiver of Past Defaults. The Holders of a
majority in aggregate principal amount of the Securities by notice to the
Trustee may waive an existing Default and its consequences except (i) a Default
in the payment of the principal of or interest on a Security or (ii) a Default
in respect of a provision that under Section 9.02 cannot be amended without the
consent of each Securityholder affected. When a Default is waived, it is deemed
cured, but no such waiver shall extend to any subsequent or other Default or
impair any consequent right.

                  SECTION 6.05 Control by Majority. The Holders of a majority in
aggregate principal amount of the Securities may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee with respect to the
Securities. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture or, subject to Section 7.01, that the
Trustee determines is unduly prejudicial to the rights of other Securityholders
or would involve the Trustee in personal liability; provided, however, that the
Trustee may take any other action deemed proper by the Trustee that is not
inconsistent with such direction. Prior to taking any action hereunder, the
Trustee shall be entitled to reasonable indemnity against all losses and
expenses caused by taking or not taking such action.

                  SECTION 6.06 Limitation on Suits. A Securityholder may not
pursue any remedy with respect to this Indenture or the Securities unless:

                                       47
<PAGE>

                  (1) such Holder shall have previously given to the Trustee
         written notice of a continuing Event of Default;

                  (2) the Holders of at least 25% in aggregate principal amount
         of the Securities then outstanding shall have made a written request,
         and such Holder of or Holders shall have offered reasonable indemnity,
         to the Trustee to pursue such proceeding as trustee; and

                  (3) the Trustee has failed to institute such proceeding and
         has not received from the Holders of at least a majority in aggregate
         principal amount of the Securities outstanding a direction inconsistent
         with such request, within 60 days after such notice, request and offer.

                  The foregoing limitations on the pursuit of remedies by a
Securityholder shall not apply to a suit instituted by a Holder of Securities
for the enforcement of payment of the principal of or interest on such Security
on or after the applicable due date specified in such Security. A Securityholder
may not use this Indenture to prejudice the rights of another Securityholder or
to obtain a preference or priority over another Securityholder.

                  SECTION 6.07 Rights of Holders To Receive Payment.
Notwithstanding any other provision of this Indenture, the right of any Holder
to receive payment of principal of and interest on the Securities held by such
Holder, on or after the respective due dates expressed in this Securities, or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

                  SECTION 6.08 Collection Suit by Trustee. If an Event of
Default specified in Section 6.01(1) or (2) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust
against the Company for the whole amount then due and owing (together with
interest on any unpaid interest to the extent lawful) and the amounts provided
for in Section 7.07.

                  SECTION 6.09 Trustee May File Proofs of Claim. The Trustee may
file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, its creditors or
its property and, unless prohibited by law or applicable regulations, may vote
on behalf of the Holders in any election of a trustee in bankruptcy or other
Person performing similar functions, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and its counsel, and any other amounts due the Trustee under Section
7.07.

                  SECTION 6.10 Priorities. If the Trustee collects any money or
property pursuant to this Article 6, it shall pay out the money or property in
the following order:

                           FIRST: to the Trustee for amounts due under Section
                  7.07;

                                       48
<PAGE>

                           SECOND: to holders of Senior Indebtedness of the
                  Company to the extent required by Article 10;

                           THIRD: to Securityholders for amounts due and unpaid
                  on the Securities for principal and interest, ratably, without
                  preference or priority of any kind, according to the amounts
                  due and payable on the Securities for principal and interest,
                  respectively; and

                           FOURTH: to the Company.

                  The Trustee may fix a record date and payment date for any
payment to Securityholders pursuant to this Section.

At least 15 days before such record date, the Company shall mail to each
Securityholder and the Trustee a notice that states the record date, the payment
date and amount to be paid.

                  SECTION 6.11 Undertaking for Costs. In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by
Holders of more than 10% in aggregate principal amount of the Securities.

                  SECTION 6.12 Waiver of Stay or Extension Laws. The Company (to
the extent it may lawfully do so) shall not at any time insist upon, or plead,
or in any manner whatsoever claim or take the benefit or advantage of, any stay
or extension law wherever enacted, now or at any time hereafter in force, which
may affect the covenants or the performance of this Indenture; and the Company
(to the extent that it may lawfully do so) hereby expressly waives all benefit
or advantage of any such law, and shall not hinder, delay or impede the
execution of any power herein granted to the Trustee, but shall suffer and
permit the execution of every such power as though no such law had been enacted.

                                   ARTICLE 7

                                     Trustee

                  SECTION 7.01 Duties of Trustee. (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 exercise or use under the circumstances
in the conduct of such Person's own affairs.

                                       49
<PAGE>

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

                  (1) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture and no
         implied covenants or obligations shall be read into this Indenture
         against the Trustee; and

                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, 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 wilful misconduct,
except that:

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

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

                  (3) the Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith in accordance with a direction
         received by it pursuant to Section 6.05.

                  (d) Every provision of this Indenture that in any way relates
to the Trustee is subject to paragraphs (a), (b) and (c) of this Section.

                  (e) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

                  (f) Money held in trust by the Trustee need not be segregated
from other funds except to the extent required by law.

                  (g) No provision of this Indenture shall require the Trustee
to expend or risk its own funds or otherwise incur 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 to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

                  (h) Every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section and to the provisions of the TIA.

                  SECTION 7.02 Rights of Trustee. (a) The Trustee may rely on
any document believed by it to be genuine and to have been signed or presented
by the proper person. The Trustee need not investigate any fact or matter stated
in the document.

                                       50
<PAGE>

                  (b) Before the Trustee acts or refrains from acting, it may
require an Officers' Certificate or an Opinion of Counsel. The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on
the Officers' Certificate or Opinion of Counsel.

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

                  (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers; provided, however, that the Trustee's conduct does not
constitute wilful misconduct or negligence.

                  (e) The Trustee may consult with counsel, and the advice or
opinion of counsel with respect to legal matters relating to this Indenture and
the Securities shall be full and complete authorization and protection from
liability in respect to any action taken, omitted or suffered by it hereunder in
good faith and in accordance with the advice or opinion of such counsel.

                  SECTION 7.03 Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar or
co-registrar may do the same with like rights. However, the Trustee must comply
with Sections 7.10 and 7.11.

                  SECTION 7.04 Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Securities, it shall not be accountable for the Company's
use of the proceeds from the Securities, and it shall not be responsible for any
statement of the Company or any Subsidiary Guarantor in this Indenture or in any
document issued in connection with the sale of the Securities or in the
Securities other than the Trustee's certificate of authentication.

                  SECTION 7.05 Notice of Defaults. If a Default occurs and is
continuing and if it is known to the Trustee, the Trustee shall mail to each
Securityholder notice of the Default within 90 days after it is known to a Trust
Officer or written notice of it is received by the Trustee. Except in the case
of a Default in payment of principal of or interest on any Security, the Trustee
may withhold the notice if and so long as a committee of its Trust Officers in
good faith determines that withholding the notice is in the interests of
Securityholders.

                  The Trustee is not required to take notice or deemed to have
notice of any Event of Default with respect to the Securities, except an Event
of Default under Section 6.01(1) or 6.01(2) hereof, unless a Trust Officer shall
have received written notice of such Event of Default from the Company, any
Subsidiary Guarantor or any Securityholder or unless a Trust Officer shall
otherwise have knowledge thereof.

                  SECTION 7.06 Reports by Trustee to Holders. (a) As promptly as
practicable after each May 15 beginning with May 15, 2002, and in any event
prior to July 15 in each year, the Trustee shall mail to each Securityholder a
brief report dated as of May 15 each year that complies with TIA Section 313(a),
if and to the extent required by said subsection. The Trustee also shall comply
with TIA Section 313(b).

                                       51
<PAGE>

                  A copy of each report at the time of its mailing to
Securityholders shall be filed with the SEC and each stock exchange (if any) on
which the Securities are listed. The Company agrees to notify promptly the
Trustee whenever the Securities become listed on any stock exchange and of any
delisting thereof.

                  (b) Upon written request by the Trustee, the Company will
furnish or cause to be furnished to the Trustee within 30 days after the receipt
by the Company of any such request, a list, in such form as the Trustee may
reasonably require, of the names and addresses of the Holders as of a date not
more than 15 days prior to the time such list is furnished; provided, however,
that is and so long as the Trustee shall be the security registrar, no such list
need be furnished.

                  SECTION 7.07 Compensation and Indemnity. The Company shall pay
to the Trustee from time to time reasonable compensation for its services. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it,
including costs of collection, in addition to the compensation for its services.
Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Trustee's agents, counsel, accountants and
experts. The Company shall indemnify the Trustee against any and all loss,
liability or expense (including attorneys' fees) incurred by it in connection
with the acceptance and administration of this trust and the performance of its
duties hereunder. The Trustee shall notify the Company promptly of any claim for
which it may seek indemnity. Failure by the Trustee to so notify the Company
shall not relieve the Company of its obligations hereunder. The Company shall
defend the claim and the Trustee may have separate counsel and the Company shall
pay the fees and expenses of such counsel. The Company need not reimburse any
expense or indemnify against any loss, liability or expense incurred by the
Trustee through the Trustee's own wilful misconduct, negligence or bad faith.
The Company need not pay for any settlement made by the Trustee without the
Company's consent, such consent not to be unreasonably withheld.

                  To secure the Company's payment obligations in this Section,
the Trustee shall have a lien prior to the Securities on all money or property
held or collected by the Trustee other than money or property held in trust to
pay principal of and interest on particular Securities.

                  The Company's payment obligations pursuant to this Section
shall survive the discharge of this Indenture. When the Trustee incurs expenses
after the occurrence of a Default specified in Section 6.01(6) or (7), the
expenses are intended to constitute expenses of administration under the
Bankruptcy Law.

                  SECTION 7.08 Replacement of Trustee. The Trustee may resign at
any time by so notifying the Company. The Holders of a majority in aggregate
principal amount of the Securities may remove the Trustee by so notifying the
Trustee and may appoint a successor Trustee. The Company shall remove the
Trustee if:

                  (1) the Trustee fails to comply with Section 7.10;

                  (2) the Trustee is adjudged bankrupt or insolvent;

                                       52
<PAGE>

                  (3) a receiver or other public officer takes charge of the
         Trustee or its property; or

                  (4) the Trustee otherwise becomes incapable of acting.

                  If the Trustee resigns, is removed by the Company or by the
Holders of a majority in aggregate principal amount of the Securities and such
Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy
exists in the office of Trustee for any reason (the Trustee in such event being
referred to herein as the retiring Trustee), the Company shall promptly appoint
a successor Trustee.

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.07.

                  If a successor Trustee does not take office within 60 days
after the retiring Trustee resigns or is removed, the retiring Trustee or the
Holders of 10% in aggregate principal amount of the Securities may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

                  If the Trustee fails to comply with Section 7.10, any
Securityholder who has been a bona fide Holder of a Security for at least six
months may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee.

                  Notwithstanding the replacement of the Trustee pursuant to
this Section, the Company's obligations under Section 7.07 shall continue for
the benefit of the retiring Trustee.

                  SECTION 7.09 Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation or banking
association without any further act shall be the successor Trustee.

                  In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created
by this Indenture any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any such successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have.

                  SECTION 7.10 Eligibility; Disqualification. The Trustee shall
at all times satisfy the requirements of TIA Section 310(a). The Trustee shall
have a combined capital and surplus of at least $50,000,000 as set forth in its
most recent published annual report of

                                       53
<PAGE>

condition. The Trustee shall comply with TIA Section 310(b), subject to the
penultimate paragraph thereof; provided, however, that there shall be excluded
from the operation of TIA Section 310(b)(1) any 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 7.11 Preferential Collection of Claims Against
Company. The Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311(b). A Trustee who has resigned
or been removed shall be subject to TIA Section 311(a) to the extent indicated.

                                   ARTICLE 8

                       Discharge of Indenture; Defeasance

                  SECTION 8.01 Discharge of Liability on Securities; Defeasance.
(a) When (i) the Company delivers to the Trustee all outstanding Securities
(other than Securities replaced pursuant to Section 2.07) for cancelation or
(ii) all outstanding Securities have become due and payable, whether at maturity
or as a result of the mailing of a notice of redemption pursuant to Article 3
and the Company irrevocably deposits with the Trustee funds sufficient to pay at
maturity or upon redemption all outstanding Securities, including interest
thereon to maturity or such redemption date (other than Securities replaced
pursuant to Section 2.07), and if in either case the Company pays all other sums
payable hereunder by the Company, then this Indenture shall, subject to Sections
8.01(c), cease to be of further effect. The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of the Company
accompanied by an Officers' Certificate and an Opinion of Counsel and at the
cost and expense of the Company.

                  (b) Subject to Sections 8.01(c) and 8.02, the Company at any
time may terminate (i) all its obligations under the Securities and this
Indenture ("legal defeasance option") or (ii) its obligations under Sections
4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.09, 4.10, 4.13, 4.14 and 4.15, the
operation of Sections 6.01(4) (to the extent relating to such other Sections),
6.01(5), 6.01(6), 6.01(7), 6.01(8) and 6.01(9) (but, in the case of Sections
6.01(6) and (7), with respect only to Significant Subsidiaries), its obligations
under Sections 5.01(iv) and 5.02 and the related operation of Section 6.01(3)
("covenant defeasance option"). The Company may exercise its legal defeasance
option notwithstanding its prior exercise of its covenant defeasance option.

                  If the Company exercises its legal defeasance option, payment
of the Securities may not be accelerated because of an Event of Default. If the
Company exercises its covenant defeasance option, payment of the Securities may
not be accelerated because of an Event of Default specified in Sections 6.01(3)
and 6.01(4) (with respect to the provisions of Articles 4 and 5 referred to in
the immediately preceding paragraph) and Sections 6.01(5), 6.01(6), 6.01(7),
6.01(8) and 6.01(9) (but, in the case of Sections 6.01(6) and (7), with respect
only to Significant Subsidiaries). If the Company exercises its legal defeasance
option or its covenant defeasance option, each Subsidiary Guarantor, if any,
shall be released from all its obligations under its Subsidiary Guaranty.

                                       54
<PAGE>

                  Upon satisfaction of the conditions set forth herein and upon
request of the Company, the Trustee shall acknowledge in writing the discharge
of those obligations that the Company terminates.

                  (c) Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.04, 2.05, 2.06, 2.07, 7.07, 7.08, 8.05 and 8.06 and
Appendix A shall survive until the Securities have been paid in full.
Thereafter, the Company's obligations in Sections 7.07 and 8.05 shall survive.

                  SECTION 8.02 Conditions to Defeasance. The Company may
exercise its legal defeasance option or its covenant defeasance option only if:

                  (1) the Company irrevocably deposits in trust with the Trustee
         money or U.S. Government Obligations for the payment of principal of
         and interest on the Securities to maturity or redemption, as the case
         may be;

                  (2) the Company delivers to the Trustee a certificate from a
         nationally recognized firm of independent accountants expressing their
         opinion that the payments of principal and interest when due and
         without reinvestment on the deposited U.S. Government Obligations plus
         any deposited money without investment will provide cash at such times
         and in such amounts as will be sufficient to pay principal and interest
         when due on all the Securities to maturity or redemption, as the case
         may be;

                  (3) 123 days pass after the deposit is made and during the
         123-day period no Default specified in Section 6.01(6) or (7) with
         respect to the Company occurs which is continuing at the end of the
         period;

                  (4) the deposit does not constitute a default under any other
         agreement binding on the Company and is not prohibited by Article 10;

                  (5) the Company delivers to the Trustee an Opinion of Counsel
         to the effect that the trust resulting from the deposit does not
         constitute, or is qualified as, a regulated investment company under
         the Investment Company Act of 1940;

                  (6) in the case of the legal defeasance option, 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
         law, in either case to the effect that, and based thereon such Opinion
         of Counsel shall confirm that, the Securityholders will not recognize
         income, gain or loss for Federal income tax purposes as a result of
         such 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 defeasance had not occurred;

                  (7) in the case of the covenant defeasance option, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Securityholders 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

                                       55
<PAGE>

         the same manner and at the same times as would have been the case if
         such covenant defeasance had not occurred; and

                  (8) the Company delivers to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent to the defeasance and discharge of the Securities as
         contemplated by this Article 8 have been complied with.

                  Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article 3.

                  SECTION 8.03 Application of Trust Money. The Trustee shall
hold in trust money or U.S. Government Obligations deposited with it pursuant to
this Article 8. It shall apply the deposited money and the money from U.S.
Government Obligations through the Paying Agent and in accordance with this
Indenture to the payment of principal of and interest on the Securities. Money
and securities so held in trust are not subject to Article 10.

                  SECTION 8.04 Repayment to Company. The Trustee and the Paying
Agent shall promptly turn over to the Company upon request any excess money or
securities held by them at any time.

                  Subject to any applicable abandoned property law, the Trustee
and the Paying Agent shall pay to the Company upon request any money held by
them for the payment of principal or interest that remains unclaimed for two
years, and, thereafter, Securityholders entitled to the money must look to the
Company for payment as general creditors.

                  SECTION 8.05 Indemnity for Government Obligations. The Company
shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against deposited U.S. Government Obligations or the
principal and interest received on such U.S. Government Obligations.

                  SECTION 8.06 Reinstatement. If the Trustee or Paying Agent is
unable to apply any money or U.S. Government Obligations in accordance with this
Article 8 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article 8 until such time as the Trustee
or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article 8; provided, however, that, if the
Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee or Paying Agent.

                                   Amendments

                  SECTION 9.01 Without Consent of Holders. The Company and the
Trustee may amend this Indenture or the Securities without notice to or consent
of any Securityholder:

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

                  (2) to comply with Article 5;

                  (3) to provide for uncertificated Securities in addition to or
         in place of certificated Securities;

                  (4) to make any change in Article 10 or Article 12 that would
         limit or terminate the benefits available to any holder of Senior
         Indebtedness of the Company or any Subsidiary Guarantor (or
         Representatives therefor) under Article 10 or Article 12, respectively;

                  (5) to add or to remove Subsidiary Guarantors when permitted
         by the terms hereof, or to secure the Securities;

                  (6) to add to the covenants of the Company for the benefit of
         the Holders or to surrender any right or power herein conferred upon
         the Company;

                  (7) to comply with any requirements of the SEC in connection
         with qualifying, or maintaining the qualification of, this Indenture
         under the TIA; or

                  (8) to make any change that does not adversely affect the
         rights of any Securityholder.

                  An amendment under this Section may not make any change that
adversely affects the rights under Article 10 or Article 12 of any holder of
Designated Senior Indebtedness then outstanding unless the holders of such
Designated Senior Indebtedness (or their Representative) consent in writing to
such change.

                  After an amendment under this Section becomes effective, the
Company shall mail to Securityholders a notice briefly describing such
amendment. The failure to give such notice to all Securityholders, or any defect
therein, shall not impair or affect the validity of an amendment under this
Section.

                  SECTION 9.02 With Consent of Holders. The Company and the
Trustee may amend this Indenture or the Securities without notice to any
Securityholder but with the written consent of the Holders of at least a
majority in aggregate principal amount of the Securities. However, without the
consent of each Securityholder affected thereby an amendment or waiver may not:

                                       57
<PAGE>

                  (1) reduce the amount of Securities whose Holders must consent
         to an amendment or waiver;

                  (2) reduce the rate of or change the time for payment of
         interest on any Security;

                  (3) reduce the principal of or extend the Stated Maturity of
         any Security;

                  (4) reduce the amount payable upon the redemption or
         repurchase of any Security in accordance with Article 3 or Section 4.06
         or 4.09, or change the time at which any Security may be redeemed in
         accordance with Article 3;

                  (5) at any time after a Change of Control or an Asset Sale has
         occurred, change the time at which the Change of Control Offer or
         Prepayment Offer relating thereto must be made or at which the
         Securities must be repurchased pursuant to such Change of Control Offer
         or Prepayment Offer or make any other changes to Sections 4.06 or 4.09
         or the definitions related thereto;

                  (6) make any Security payable in a currency other than that
         stated in the Security;

                  (7) make any change in Article 10 or Article 12 that adversely
         affects the rights of any Securityholder under Article 10 or Article
         12;

                  (8) make any change in any Subsidiary Guaranty that would
         adversely affect the Securityholders;

                  (9) impair the right of any Holder to institute suit for
         enforcement of any payment on or with respect to such Holder's
         Securities or any Subsidiary Guaranty;

                  (10) release any security that may have been granted to the
         Trustee in respect of the Securities; or

                  (11) make any change in Section 6.04 or 6.07 or the second
         sentence of this Section.

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

                  An amendment under this Section may not make any change that
adversely affects the rights under Article 10 or Article 12 of any holder of
Designated Senior Indebtedness then outstanding unless the holders of such
Designated Senior Indebtedness (or their Representative) consent in writing to
such change.

                  After an amendment under this Section becomes effective, the
Company shall mail to Securityholders a notice briefly describing such
amendment. The failure to give such

                                       58
<PAGE>

notice to all Securityholders, or any defect therein, shall not impair or affect
the validity of an amendment under this Section.

                  SECTION 9.03 Compliance with Trust Indenture Act. Every
amendment to this Indenture or the Securities shall comply with the TIA as then
in effect.

                  SECTION 9.04 Revocation and Effect of Consents and Waivers. A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder's
Security or portion of the Security if the Trustee receives the notice of
revocation before the date the amendment or waiver becomes effective. After an
amendment or waiver becomes effective, it shall bind every Securityholder. An
amendment or waiver becomes effective upon the execution of such amendment or
waiver by the Trustee.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Securityholders entitled to give their
consent or take any other action described above or required or permitted to be
taken pursuant to this Indenture. If a record date is fixed, then
notwithstanding the immediately preceding paragraph, those Persons who were
Securityholders at such record date (or their duly designated proxies), and only
those Persons, shall be entitled to give such consent or to revoke any consent
previously given or to take any such action, whether or not such Persons
continue to be Holders after such record date. No such consent shall be valid or
effective for more than 120 days after such record date.

                  SECTION 9.05 Notation on or Exchange of Securities. If an
amendment changes the terms of a Security, the Trustee may require the Holder of
the Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Security shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

                  SECTION 9.06 Trustee To Sign Amendments. The Trustee shall
sign any amendment authorized pursuant to this Article 9 if such amendment does
not adversely affect the rights, duties, liabilities or immunities of the
Trustee. If it does, the Trustee may but need not sign it. In signing such
amendment the Trustee shall be entitled to receive indemnity reasonably
satisfactory to it and to receive, and (subject to Section 7.01) shall be fully
protected in relying upon, an Officers' Certificate and an Opinion of Counsel
stating that such amendment is authorized or permitted by this Indenture.

                  SECTION 9.07 Payment for Consent. Neither the Company nor any
Affiliate of the Company shall, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of this Indenture or the Securities unless such consideration is
offered to be paid to all Holders that so consent, waive or

                                       59
<PAGE>

agree to amend in the time frame set forth in solicitation documents relating to
such consent, waiver or agreement.

                                   ARTICLE 10

                                  Subordination

                  SECTION 10.01 Agreement To Subordinate. The Company agrees,
and each Securityholder by accepting a Security agrees, that the Indebtedness
evidenced by the Securities is subordinated in right of payment, to the extent
and in the manner provided in this Article 10, to the payment when due of all
Senior Indebtedness of the Company and that the subordination is for the benefit
of and enforceable by the holders of such Senior Indebtedness. The Securities
shall in all respects rank pari passu with all existing and future Pari Passu
Indebtedness of the Company (including the Company's 8 3/4% Senior Subordinated
Notes due 2007) and senior to all future Subordinated Indebtedness of the
Company, and only Senior Indebtedness of the Company shall rank senior to the
Securities in accordance with the provisions set forth herein. All provisions of
this Article 10 shall be subject to Section 10.12.

                  SECTION 10.02 Liquidation, Dissolution, Bankruptcy. Upon any
payment or distribution of the assets of the Company to creditors upon a total
or partial liquidation or a total or partial dissolution of the Company or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company or its property:

                  (1) holders of Senior Indebtedness of the Company shall be
         entitled to receive payment in full of such Senior Indebtedness before
         Securityholders shall be entitled to receive any payment of principal
         of or interest on the Securities; and

                  (2) until such Senior Indebtedness is paid in full, any
         distribution made by or on behalf of the Company to which
         Securityholders would be entitled but for this Article 10 shall be made
         to holders of such Senior Indebtedness as their interests may appear,
         except that all Securityholders may receive and retain shares of stock
         and any debt securities that are subordinated to all Senior
         Indebtedness of the Company to at least the same extent as the
         Securities.

                  SECTION 10.03 Default on Senior Indebtedness. The Company may
not pay the principal of, premium, if any, on or interest on the Securities or
make any deposit pursuant to Section 8.01 and may not repurchase, redeem or
otherwise retire any Securities (collectively, "pay the Securities") if (i) any
principal, premium, if any, interest or other amounts due in respect of any
Senior Indebtedness of the Company is not paid within any applicable grace
period (including at maturity) or (ii) any other default on Senior Indebtedness
of the Company occurs and the maturity of such Senior Indebtedness is
accelerated in accordance with its terms unless, in either case, (x) the default
has been cured or waived and any such acceleration has been rescinded or (y)
such Senior Indebtedness has been paid in full; provided, however, that the
Company may pay the Securities without regard to the foregoing if the Company
and the Trustee receive written notice approving such payment from the
Representative of each issue of Designated Senior Indebtedness. During the
continuance of any default (other than a default described in clause (i) or (ii)
of the preceding sentence) with respect

                                       60
<PAGE>

to any Designated Senior Indebtedness pursuant to which the maturity thereof may
be accelerated immediately without further notice (except such notice as may be
required to effect such acceleration), the Company may not pay the Securities
for a period (a "Payment Blockage Period") commencing upon the receipt by the
Company and the Trustee of written notice of such default from the
Representative of the holders of such Designated Senior Indebtedness specifying
an election to effect a Payment Blockage Period (a "Payment Blockage Notice")
and ending 179 days after receipt of such notice by the Company and the Trustee
unless earlier terminated (i) by written notice to the Trustee and the Company
from the Representative who gave such Payment Blockage Notice, (ii) because such
Designated Senior Indebtedness has been repaid in full or (iii) because the
default giving rise to such Payment Blockage Notice is no longer continuing.
Notwithstanding the provisions described in the immediately preceding sentence,
unless the holders of such Designated Senior Indebtedness or the Representative
of such holders shall have accelerated the maturity of such Designated Senior
Indebtedness and not rescinded such acceleration, the Company may (unless
otherwise prohibited as described in the first sentence of this paragraph)
resume payments on the Securities after the end of such Payment Blockage Period.
No more than one Payment Blockage Notice may be given in any consecutive 360-day
period regardless of the number of defaults with respect to one or more issues
of Senior Indebtedness. No default with respect to Designated Senior
Indebtedness that existed or was continuing on the date of the commencement of
any Payment Blockage Period will be, or can be, made for the basis for the
commencement of a second Payment Blockage Period, whether or not within a period
of 365 consecutive days, unless such default has been cured or waived for a
period of not less than 90 consecutive days subsequent to the end of such
initial Payment Blockage Period.

                  SECTION 10.04 Acceleration of Payment of Securities. If
payment of the Securities is accelerated because of an Event of Default, the
Company or the Trustee shall promptly notify the holders of the Designated
Senior Indebtedness (or their Representatives) of the acceleration.

                  SECTION 10.05 When Distribution Must Be Paid Over. If a
distribution is made to Securityholders that because of this Article 10 should
not have been made to them, the Securityholders who receive the distribution
shall hold it in trust for holders of Senior Indebtedness of the Company and pay
it over to them as their interests may appear.

                  SECTION 10.06 Subrogation. After all Senior Indebtedness of
the Company is paid in full and until the Securities are paid in full,
Securityholders shall be subrogated to the rights of holders of such Senior
Indebtedness to receive distributions applicable to such Senior Indebtedness. A
distribution made under this Article 10 to holders of such Senior Indebtedness
which otherwise would have been made to Securityholders is not, as between the
Company and Securityholders, a payment by the Company on such Senior
Indebtedness.

                  SECTION 10.07 Relative Rights. This Article 10 defines the
relative rights of Securityholders and holders of Senior Indebtedness of the
Company. Nothing in this Indenture shall:

                                       61
<PAGE>

                  (1) impair, as between the Company and Securityholders, the
         obligation of the Company, which is absolute and unconditional, to pay
         principal of and interest on the Securities in accordance with their
         terms; or

                  (2) prevent the Trustee or any Securityholder from exercising
         its available remedies upon a Default or an Event of Default, subject
         to the rights of holders of Senior Indebtedness of the Company to
         receive distributions otherwise payable to Securityholders.

                  SECTION 10.08 Subordination May Not Be Impaired by Company. No
right of any holder of Senior Indebtedness of the Company to enforce the
subordination of the Indebtedness evidenced by the Securities shall be impaired
by any act or failure to act by the Company or by its failure to comply with
this Indenture.

                  SECTION 10.09 Rights of Trustee and Paying Agent.
Notwithstanding Section 10.03, the Trustee or Paying Agent may continue to make
payments on the Securities and shall not be charged with knowledge of the
existence of facts that would prohibit the making of any such payments unless,
not less than two Business Days prior to the date of such payment, a Trust
Officer receives notice satisfactory to it that payments may not be made under
this Article 10. The Company, the Registrar or co-registrar, the Paying Agent, a
Representative or a holder of Senior Indebtedness may give the notice; provided,
however, that, if an issue of Senior Indebtedness of the Company has a
Representative, only the Representative may give the notice.

                  The Trustee in its individual or any other capacity may hold
Senior Indebtedness of the Company with the same rights it would have if it were
not Trustee. The Registrar and co-registrar and the Paying Agent may do the same
with like rights. The Trustee shall be entitled to all the rights set forth in
this Article 10 with respect to any Senior Indebtedness of the Company which may
at any time be held by it, to the same extent as any other holder of such Senior
Indebtedness; and nothing in Article 7 shall deprive the Trustee of any of its
rights as such holder. Nothing in this Article 10 shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 7.07.

                  SECTION 10.10 Distribution or Notice to Representative.
Whenever a distribution is to be made or a notice given to holders of Senior
Indebtedness of the Company, the distribution may be made and the notice given
to their Representative (if any).

                  SECTION 10.11 Article 10 Not To Prevent Events of Default or
Limit Right To Accelerate. The failure to make a payment pursuant to the
Securities by reason of any provision in this Article 10 shall not be construed
as preventing the occurrence of a Default. Nothing in this Article 10 shall have
any effect on the right of the Securityholders or the Trustee to accelerate the
maturity of the Securities.

                  SECTION 10.12 Trust Moneys Not Subordinated. Notwithstanding
anything contained herein to the contrary, payments from money or the proceeds
of U.S. Government Obligations held in trust under Article 8 by the Trustee for
the payment of principal of 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 10, and none of the

                                       62
<PAGE>

Securityholders shall be obligated to pay over any such amount to the Company or
any holder of Senior Indebtedness of the Company or any other creditor of the
Company.

                  SECTION 10.13 Trustee Entitled To Rely. Upon any payment or
distribution pursuant to this Article 10, the Trustee and the Securityholders
shall be entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 10.02
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representatives for the holders of Senior
Indebtedness of the Company for the purpose of ascertaining the Persons entitled
to participate in such payment or distribution, the holders of such 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 10. In the event that the Trustee
determines, in good faith, that evidence is required with respect to the right
of any Person as a holder of Senior Indebtedness of the Company to participate
in any payment or distribution pursuant to this Article 10, the Trustee may
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of such Senior Indebtedness held by such Person, the
extent to which such Person is entitled to participate in such payment or
distribution and other facts pertinent to the rights of such Person under this
Article 10, 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 provisions of Sections 7.01 and 7.02 shall
be applicable to all actions or omissions of actions by the Trustee pursuant to
this Article 10.

                  SECTION 10.14 Trustee To Effectuate Subordination. Each
Securityholder by accepting a Security authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination between the Securityholders and the holders of
Senior Indebtedness of the Company as provided in this Article 10 and appoints
the Trustee as attorney-in-fact for any and all such purposes.

                  SECTION 10.15 Trustee Not Fiduciary for Holders of Senior
Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness and shall not be liable to any such holders if it
shall mistakenly pay over or distribute to Securityholders or the Company or any
other Person, money or assets to which any holders of Senior Indebtedness of the
Company shall be entitled by virtue of this Article 10 or otherwise.

                  SECTION 10.16 Reliance by Holders of Senior Indebtedness on
Subordination Provisions. Each Securityholder by accepting a Security
acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a consideration to each holder of any Senior
Indebtedness of the Company, whether such Senior Indebtedness was created or
acquired before or after the issuance of the Securities, to acquire and continue
to hold, or to continue to hold, such Senior Indebtedness and such holder of
such Senior Indebtedness shall be deemed conclusively to have relied on such
subordination provisions in acquiring and continuing to hold, or in continuing
to hold, such Senior Indebtedness.

                                   ARTICLE 11

                              Subsidiary Guaranties

                  SECTION 11.01 Guaranties. Each Subsidiary Guarantor hereby
unconditionally guarantees, jointly and severally, to each Holder and to the
Trustee and its successors and assigns (a) the full and punctual payment of
principal of and interest on the Securities when due, whether at maturity, by
acceleration, by redemption or otherwise, and all other monetary obligations of
the Company under this Indenture and the Securities and (b) the full and
punctual performance within applicable grace periods of all other obligations of
the Company under this Indenture and the Securities (all the foregoing being
hereinafter collectively called the "Obligations"). Each Subsidiary Guarantor
further agrees that the Obligations may be extended or renewed, in whole or in
part, without notice or further assent from such Subsidiary Guarantor and that
such Subsidiary Guarantor will remain bound under this Article 11
notwithstanding any extension or renewal of any Obligation.

                  Each Subsidiary Guarantor waives presentation to, demand of,
payment from and protest to the Company of any of the Obligations and also
waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice
of any default under the Securities or the Obligations. The obligations of each
Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any
Holder or the Trustee to assert any claim or demand or to enforce any right or
remedy against the Company or any other Person under this Indenture, the
Securities or any other agreement or otherwise; (b) any extension or renewal of
any thereof; (c) any rescission, waiver, amendment or modification of any of the
terms or provisions of this Indenture, the Securities or any other agreement;
(d) the release of any security held by any Holder or the Trustee for the
Obligations or any of them; (e) the failure of any Holder or the Trustee to
exercise any right or remedy against any other guarantor of the Obligations; or
(f) any change in the ownership of such Subsidiary Guarantor.

                  Each Subsidiary Guarantor further agrees that its Subsidiary
Guaranty herein constitutes a guarantee of payment, performance and compliance
when due (and not a guarantee of collection) and waives any right to require
that any resort be had by any Holder or the Trustee to any security held for
payment of the Obligations.

                  Each Subsidiary Guaranty is, to the extent and in the manner
set forth in Article 12, subordinated and subject in right of payment to the
prior payment in full of all Senior Indebtedness of the Subsidiary Guarantor
giving such Subsidiary Guaranty and each Subsidiary Guaranty is made subject to
such provisions of this Indenture.

                  Except as expressly set forth in Sections 4.15, 5.02 and
8.01(b), the obligations of each Subsidiary Guarantor hereunder shall not be
subject to any reduction, limitation, impairment or termination for any reason,
including any claim of waiver, release, surrender, alteration or compromise, and
shall not be subject to any defense of setoff, counterclaim, recoupment or
termination whatsoever or by reason of the invalidity, illegality or
unenforceability of the Obligations or otherwise. Without limiting the
generality of the foregoing, the obligations of each Subsidiary Guarantor herein
shall not be discharged or impaired or otherwise affected by the failure of any
Holder or the Trustee to assert any claim or

                                       64
<PAGE>

demand or to enforce any remedy under this Indenture, the Securities or any
other agreement, by any waiver or modification of any thereof, by any default,
failure or delay, willful or otherwise, in the performance of the obligations,
or by any other act or thing or omission or delay to do any other act or thing
which may or might in any manner or to any extent vary the risk of such
Subsidiary Guarantor or would otherwise operate as a discharge of such
Subsidiary Guarantor as a matter of law or equity.

                  Each Subsidiary Guarantor further agrees that its Subsidiary
Guaranty herein shall continue to be effective or be reinstated, as the case may
be, if at any time payment, or any part thereof, of principal of or interest on
any Obligation is rescinded or must otherwise be restored by any Holder or the
Trustee upon the bankruptcy or reorganization of the Company or otherwise.

                  In furtherance of the foregoing and not in limitation of any
other right which any Holder or the Trustee has at law or in equity against any
Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay
the principal of or interest on any Obligation when and as the same shall become
due, whether at maturity, by acceleration, by redemption or otherwise, or to
perform or comply with any other Obligation, each Subsidiary Guarantor hereby
promises to and will, upon receipt of written demand by the Trustee, forthwith
pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal
to the sum of (i) the unpaid amount of such Obligations, (ii) accrued and unpaid
interest on such Obligations (but only to the extent not prohibited by law) and
(iii) all other monetary Obligations of the Company to the Holders and the
Trustee.

                  Each Subsidiary Guarantor agrees that it shall not be entitled
to any right of subrogation in respect of any Obligations guaranteed hereby
until payment in full in cash of all Obligations and all obligations to which
the Obligations are subordinated as provided in Article 12. Each Subsidiary
Guarantor further agrees that, as between it, 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 6 for the purposes
of such Subsidiary Guarantor's Subsidiary Guaranty herein, notwithstanding any
stay, injunction or other prohibition preventing such acceleration in respect of
the Obligations guaranteed hereby, and (y) in the event of any declaration of
acceleration of such obligations as provided in Article 6, such Obligations
(whether or not due and payable) shall forthwith become due and payable by such
Subsidiary Guarantor for the purposes of this Section.

                  Each Subsidiary Guarantor also agrees to pay any and all costs
and expenses (including reasonable attorneys' fees) incurred by the Trustee or
any Holder in enforcing any rights under this Section.

                  SECTION 11.02 Contribution. Each of the Company and any
Subsidiary Guarantor (a "Contributing Party") agrees (subject to Articles 10 and
12) that, in the event a payment shall be made by any other Subsidiary Guarantor
under any Subsidiary Guaranty (the "Claiming Guarantor"), the Contributing Party
shall indemnify the Claiming Guarantor in an amount equal to the amount of such
payment multiplied by a fraction, the numerator of which shall be the net worth
of the Contributing Party on the date hereof and the denominator of which shall
be the aggregate net worth of the Company and all the Subsidiary Guarantors on
the date

                                       65
<PAGE>

hereof (or, in the case of any Subsidiary Guarantor becoming a party hereto
pursuant to Section 9.01, the date of the amendment hereto executed and
delivered by such Subsidiary Guarantor).

                  SECTION 11.03 Successors and Assigns. This Article 11 shall be
binding upon each Subsidiary Guarantor and its successors and assigns and shall
enure to the benefit of the successors and assigns of the Trustee and the
Holders and, in the event of any transfer or assignment of rights by any Holder
or the Trustee, the rights and privileges conferred upon that party in this
Indenture and in the Securities shall automatically extend to and be vested in
such transferee or assignee, all subject to the terms and conditions of this
Indenture.

                  SECTION 11.04 No Waiver. Neither a failure nor a delay on the
part of either the Trustee or the Holders in exercising any right, power or
privilege under this Article 11 shall operate as a waiver thereof, nor shall a
single or partial exercise thereof preclude any other or further exercise of any
right, power or privilege. The rights, remedies and benefits of the Trustee and
the Holders herein expressly specified are cumulative and not exclusive of any
other rights, remedies or benefits which either may have under this Article 11
at law, in equity, by statute or otherwise.

                  SECTION 11.05 Modification. No modification, amendment or
waiver of any provision of this Article 11, nor the consent to any departure by
any Subsidiary Guarantor therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Trustee, and then such waiver or
consent shall be effective only in the specific instance and for the purpose for
which given. No notice to or demand on any Subsidiary Guarantor in any case
shall entitle such Subsidiary Guarantor to any other or further notice or demand
in the same, similar or other circumstances.

                  SECTION 11.06 Execution of Supplemental Indenture for Future
Subsidiary Guarantors. Each Subsidiary which is required to become a Subsidiary
Guarantor pursuant to Section 4.13 shall promptly execute and deliver to the
Trustee a supplemental indenture in the form of Exhibit B hereto pursuant to
which such Subsidiary shall become a Subsidiary Guarantor under this Article 11
and shall guarantee the Obligations. Concurrently with the execution and
delivery of such supplemental indenture, the Company shall deliver to the
Trustee an Opinion of Counsel to the effect that such supplemental indenture has
been duly authorized, executed and delivered by such Subsidiary and that,
subject to the application of bankruptcy, insolvency, moratorium, fraudulent
conveyance or transfer and other similar laws relating to creditors' rights
generally and to the principles of equity, whether considered in a proceeding at
law or in equity, the Subsidiary Guaranty of such Subsidiary Guarantor is a
legal, valid and binding obligation of such Subsidiary Guarantor, enforceable
against such Subsidiary Guarantor in accordance with its terms.

                                   ARTICLE 12

                     Subordination of Subsidiary Guaranties

                  SECTION 12.01 Agreement To Subordinate. Each Subsidiary
Guarantor agrees, and each Securityholder by accepting a Security agrees, that
the Obligations of such Subsidiary Guarantor are subordinated in right of
payment, to the extent and in the manner

                                       66
<PAGE>

provided in this Article 12, to the payment when due of all Senior Indebtedness
of such Subsidiary Guarantor and that the subordination is for the benefit of
and enforceable by the holders of such Senior Indebtedness. The Obligations of a
Subsidiary Guarantor shall in all respects rank pari passu with all existing and
future Pari Passu Indebtedness of such Subsidiary Guarantor and senior to all
existing and future Subordinated Indebtedness of such Subsidiary Guarantor, and
only Senior Indebtedness of such Subsidiary Guarantor (including such Subsidiary
Guarantor's Guarantee of Senior Indebtedness of the Company) shall rank senior
to the Obligations of such Subsidiary Guarantor in accordance with the
provisions set forth herein.

                  SECTION 12.02 Liquidation, Dissolution, Bankruptcy. Upon any
payment or distribution of the assets of any Subsidiary Guarantor to creditors
upon a total or partial liquidation or a total or partial dissolution of such
Subsidiary Guarantor or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to such Subsidiary Guarantor or its
property:

                  (1) holders of Senior Indebtedness of such Subsidiary
         Guarantor shall be entitled to receive payment in full of such Senior
         Indebtedness before Securityholders shall be entitled to receive any
         payment pursuant to any Obligations of such Subsidiary Guarantor; and

                  (2) until the Senior Indebtedness of any Subsidiary Guarantor
         is paid in full, any distribution made by or on behalf of such
         Subsidiary Guarantor to which Securityholders would be entitled but for
         this Article 12 shall be made to holders of such Senior Indebtedness as
         their interests may appear, except that Securityholders may receive
         shares of stock and any debt securities of such Subsidiary Guarantor
         that are subordinated to Senior Indebtedness of such Subsidiary
         Guarantor to at least the same extent as the Obligations of such
         Subsidiary Guarantor are subordinated to Senior Indebtedness of such
         Subsidiary Guarantor.

                  SECTION 12.03 Default on Senior Indebtedness of Subsidiary
Guarantor. No Subsidiary Guarantor may make any payment pursuant to any of its
Obligations or repurchase, redeem or otherwise retire or defease any Securities
or other Obligations (collectively, "pay its Subsidiary Guaranty") if (i) any
Senior Indebtedness of such Subsidiary Guarantor is not paid within any
applicable grace period (including at maturity) or (ii) any other default on
Senior Indebtedness of such Subsidiary Guarantor occurs and the maturity of such
Senior Indebtedness is accelerated in accordance with its terms unless, in
either case, (x) the default has been cured or waived and any such acceleration
has been rescinded or (y) such Senior Indebtedness has been paid in full;
provided, however, that any Subsidiary Guarantor may pay its Subsidiary Guaranty
without regard to the foregoing if such Subsidiary Guarantor and the Trustee
receive written notice approving such payment from the Representatives of each
issue of Senior Indebtedness of such Subsidiary Guarantor. No Subsidiary
Guarantor may pay its Subsidiary Guaranty during the continuance of any Payment
Blockage Period after receipt by the Company and the Trustee of a Payment
Blockage Notice under Section 10.03. Notwithstanding the provisions described in
the immediately preceding sentence, unless the holders of Designated Senior
Indebtedness giving such Payment Blockage Notice or the Representative of such
holders shall have accelerated the maturity of such Designated Senior
Indebtedness and not rescinded such acceleration, any Subsidiary Guarantor may
resume (unless otherwise prohibited as

                                       67
<PAGE>

described in the first sentence of this paragraph) payments pursuant to its
Subsidiary Guaranty after such Payment Blockage Period.

                  SECTION 12.04 Demand for Payment. If a demand for payment is
made on a Subsidiary Guarantor pursuant to Article 11, the Trustee shall
promptly notify the holders of the Designated Senior Indebtedness (or their
Representatives) of such demand.

                  SECTION 12.05 When Distribution Must Be Paid Over. If a
distribution is made to Securityholders that because of this Article 12 should
not have been made to them, the Securityholders who receive the distribution
shall hold it in trust for holders of the relevant Senior Indebtedness and pay
it over to them or their Representatives as their interests may appear.

                  SECTION 12.06 Subrogation. After all Senior Indebtedness of a
Subsidiary Guarantor is paid in full and until the Securities are paid in full,
Securityholders shall be subrogated to the rights of holders of such Senior
Indebtedness to receive distributions applicable to such Senior Indebtedness. A
distribution made under this Article 12 to holders of such Senior Indebtedness
which otherwise would have been made to Securityholders is not, as between the
relevant Subsidiary Guarantor and Securityholders, a payment by such Subsidiary
Guarantor on such Senior Indebtedness.

                  SECTION 12.07 Relative Rights. This Article 12 defines the
relative rights of Securityholders and holders of Senior Indebtedness of a
Subsidiary Guarantor. Nothing in this Indenture shall:

                  (1) impair, as between a Subsidiary Guarantor and
         Securityholders, the obligation of such Subsidiary Guarantor, which is
         absolute and unconditional, to pay the Obligations to the extent set
         forth in Article 11 or the relevant Subsidiary Guaranty; or

                  (2) prevent the Trustee or any Securityholder from exercising
         its available remedies upon a default by such Subsidiary Guarantor
         under the Obligations, subject to the rights of holders of Senior
         Indebtedness of such Subsidiary Guarantor to receive distributions
         otherwise payable to Securityholders.

                  SECTION 12.08 Subordination May Not Be Impaired by Company. No
right of any holder of Senior Indebtedness of any Subsidiary Guarantor to
enforce the subordination of the Obligations of such Subsidiary Guarantor shall
be impaired by any act or failure to act by such Subsidiary Guarantor or by its
failure to comply with this Indenture.

                  SECTION 12.09 Rights of Trustee and Paying Agent.
Notwithstanding Section 12.03, the Trustee or Paying Agent may continue to make
payments on any Subsidiary Guaranty and shall not be charged with knowledge of
the existence of facts that would prohibit the making of any such payments
unless, not less than two Business Days prior to the date of such payment, a
Trust Officer receives written notice satisfactory to it that payments may not
be made under this Article 12. The Company, the relevant Subsidiary Guarantor,
the Registrar or co-registrar, the Paying Agent, a Representative or a holder of
Senior Indebtedness of any Subsidiary Guarantor may give the notice; provided,
however, that, if an issue of Senior

                                       68
<PAGE>

Indebtedness of any Subsidiary Guarantor has a Representative, only the
Representative may give the notice.

                  The Trustee in its individual or any other capacity may hold
Senior Indebtedness with the same rights it would have if it were not the
Trustee. The Registrar and co-registrar and the Paying Agent may do the same
with like rights. The Trustee shall be entitled to all the rights set forth in
this Article 12 with respect to any Senior Indebtedness of any Subsidiary
Guarantor which may at any time be held by it, to the same extent as any other
holder of Senior Indebtedness; and nothing in Article 7 shall deprive the
Trustee of any of its rights as such holder. Nothing in this Article 12 shall
apply to claims of, or payments to, the Trustee under or pursuant to Section
7.07.

                  SECTION 12.10 Distribution or Notice to Representative.
Whenever a distribution is to be made or a notice given to holders of Senior
Indebtedness of any Subsidiary Guarantor, the distribution may be made and the
notice given to their Representative (if any).

                  SECTION 12.11 Article 12 Not To Prevent Defaults Under a
Subsidiary Guaranty or Limit Right To Demand Payment. The failure to make a
payment pursuant to a Subsidiary Guaranty by reason of any provision in this
Article 12 shall not be construed as preventing the occurrence of a default
under such Subsidiary Guaranty. Nothing in this Article 12 shall have any effect
on the right of the Securityholders or the Trustee to make a demand for payment
on any Subsidiary Guarantor pursuant to Article 11 or the relevant Subsidiary
Guaranty.

                  SECTION 12.12 Trust Moneys Not Subordinated. Notwithstanding
anything contained herein to the contrary, payments from money or the proceeds
of U.S. Government Obligations held in trust under Article 8 by the Trustee for
the payment of principal of and interest on the Securities or any Subsidiary
Guaranty shall not be subordinated to the prior payment of any Senior
Indebtedness of the Company or any Subsidiary Guarantor or subject to the
restrictions set forth in this Article 12, and none of the Securityholders shall
be obligated to pay over any such amount to the Company or any Subsidiary
Guarantor or any holder of Senior Indebtedness of the Company or any Subsidiary
Guarantor or any other creditor of the Company or any Subsidiary Guarantor.

                  SECTION 12.13 Trustee Entitled To Rely. Upon any payment or
distribution pursuant to this Article 12, the Trustee and the Securityholders
shall be entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 12.02
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representatives for the holders of Senior
Indebtedness of any Subsidiary Guarantor for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of
such 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 12. In the
event that the Trustee determines, in good faith, that evidence is required with
respect to the right of any Person as a holder of Senior Indebtedness of any
Subsidiary Guarantor to participate in any payment or distribution pursuant to
this Article 12, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior

                                       69
<PAGE>

Indebtedness of such Subsidiary Guarantor held by such Person, the extent to
which such Person is entitled to participate in such payment or distribution and
other facts pertinent to the rights of such Person under this Article 12, 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 provisions of Sections 7.01 and 7.02 shall be applicable to
all actions or omissions of actions by the Trustee pursuant to this Article 12.

                  SECTION 12.14 Trustee To Effectuate Subordination. Each
Securityholder by accepting a Security authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination between the Securityholders and the holders of
Senior Indebtedness of any Subsidiary Guarantor as provided in this Article 12
and appoints the Trustee as attorney-in-fact for any and all such purposes.

                  SECTION 12.15 Trustee Not Fiduciary for Holders of Senior
Indebtedness of Subsidiary Guarantor. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Indebtedness of any Subsidiary Guarantor
and shall not be liable to any such holders if it shall mistakenly pay over or
distribute to Securityholders or the Company or any other Person, money or
assets to which any holders of such Senior Indebtedness shall be entitled by
virtue of this Article 12 or otherwise.

                  SECTION 12.16 Reliance by Holders of Senior Indebtedness on
Subordination Provisions. Each Securityholder by accepting a Security
acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a consideration to each holder of any Senior
Indebtedness of any Subsidiary Guarantor, whether such Senior Indebtedness was
created or acquired before or after the issuance of the Securities, to acquire
and continue to hold, or to continue to hold, such Senior Indebtedness and such
holder of Senior Indebtedness shall be deemed conclusively to have relied on
such subordination provisions in acquiring and continuing to hold, or in
continuing to hold, such Senior Indebtedness.

of this Indenture limits, qualifies or conflicts with another provision which is

shall control.

                  SECTION 13.04 Certificate and Opinion as to Conditions
Precedent. Upon any request or application by the Company to the Trustee to take
or refrain from taking any action under this Indenture, except to the extent
that the Company's request or application is expressly governed by another

         signers, all conditions precedent, if any, provided for in this

         counsel, all such conditions precedent have been complied with.

                  SECTION 13.05 Statements Required in Certificate or Opinion.
Each certificate or opinion with respect to compliance with a covenant or
condition provided for in this Indenture shall include:

concurred in any direction, waiver or consent, Securities owned by the Company
or by any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company shall be disregarded and
deemed not to be outstanding, except that, for the purpose of determining
whether the Trustee shall be protected in relying on any such direction, waiver
or consent, only Securities which the Trustee knows are so owned shall be so
disregarded. Also, subject to the foregoing, only Securities outstanding at the
time shall be considered in any such determination.

                  SECTION 13.07 Rules by Trustee, Paying Agent and Registrar.
The Trustee may make reasonable rules for action by or a meeting of
Securityholders. The Registrar, the Paying Agent and any co-registrar may make
reasonable rules for their functions.

                  SECTION 13.08 Legal Holidays. A "Legal Holiday" is a Saturday,
a Sunday or a day on which banking institutions are not required to be open in
the State of Texas. If a payment date is a Legal Holiday, payment shall be made
on the next succeeding day that is

                                       72

not a Legal Holiday, and no interest shall accrue for the intervening period. If

employee or stockholder, as such, of the Company or any Subsidiary Guarantor
shall not have any liability for any obligations of the Company under the
Securities or this Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. By accepting a Security, each

         2. The Securities.

         2.1 Form and Dating.

                  (a) Global Securities. Initial Securities shall be issued
initially in the form of one or more permanent global Securities in definitive,
fully registered form without interest coupons with the global securities legend
and restricted securities legend set forth in Exhibit 1 hereto (each, a "Global
Security"), which shall be deposited on behalf of the purchasers of the Initial
Securities represented thereby with the Securities Custodian, and registered in
the name of the Depository or a nominee of the Depository, duly executed by the
Company and authenticated by the Trustee as provided in this Indenture. The
aggregate principal amount of the Global Securities may from time to time be
increased or decreased by adjustments made on the records of the Trustee and the
Depository or its nominee as hereinafter provided.

                  (b) Book-Entry Provisions. This Section 2.1(b) shall apply
only to a Global Security deposited with or on behalf of the Depository.

                  The Company shall execute and the Trustee shall, in accordance
with this Section 2.1(b) and pursuant to an order of the Company, authenticate
and deliver initially one or more Global Securities that (a) shall be registered
in the name of the Depository for such Global Security or Global Securities or
the nominee of such Depository and (b) shall be delivered by the Trustee to such
Depository or pursuant to such Depository's instructions or held by the Trustee
as Securities Custodian.

                  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 by the Trustee as Securities
Custodian or under such Global Security, and the Depository may be treated by
the Company, the Trustee and any agent of the Company 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
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depository
or impair, as between the Depository and its Agent Members, the operation of
customary practices of such Depository governing the exercise of the rights of a
holder of a beneficial interest in any Global Security.

                  (c) Definitive Securities. Except as provided in Section 2.3
or 2.4, owners of beneficial interests in Global Securities will not be entitled
to receive physical delivery of certificated Securities.

         2.2 Authentication. The Trustee shall authenticate and deliver: (1)
Original Securities for original issue in an aggregate principal amount of
$200,000,000, (2) additional Initial Securities, if and when issued, in an
unlimited principal amount and (3) Exchange Securities for issue only in a
Registered Exchange Offer or a Private Exchange pursuant to a Registration
Agreement, for a like principal amount of Initial Securities, upon a written
order of the Company signed by two Officers or by an Officer and either an
Assistant Treasurer or an Assistant Secretary of the Company. Such order shall
specify the amount of the Securities to be authenticated and the date on which
the original issue of Securities is to be authenticated and

                                      A-3
<PAGE>

whether the Securities are to be Initial Securities or Exchange Securities.
Notwithstanding anything to the contrary in this Appendix or otherwise in this
Indenture, any additional issuance of Securities after the Issue Date shall be
in a principal amount of at least $25,000,000, whether such additional
Securities are of the same or a different series than the Original Securities.

         2.3 Transfer and Exchange. (a) Transfer and Exchange of Definitive
Securities. When Definitive Securities are presented to the Registrar or a
co-registrar with a request:

                  (x) to register the transfer of such Definitive Securities; or

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

the Registrar or co-registrar shall register the transfer or make the exchange
as requested if its reasonable requirements for such transaction are met;
provided, however, that the Definitive Securities surrendered for transfer or
exchange:

                  (i) shall be duly endorsed or accompanied by a written
         instrument of transfer in form reasonably satisfactory to the Company
         and the Registrar or co-registrar, duly executed by the Holder thereof
         or his attorney duly authorized in writing; and

                  (ii) are being transferred or exchanged pursuant to an
         effective registration statement under the Securities Act, pursuant to
         Section 2.3(b) or pursuant to clause (A), (B) or (C) below, and are
         accompanied by the following additional information and documents, as
         applicable:

                           (A) if such Definitive Securities are being delivered
                  to the Registrar by a Holder for registration in the name of
                  such Holder, without transfer, a certification from such
                  Holder to that effect; or

                           (B) if such Definitive Securities are being
                  transferred to the Company, a certification to that effect; or

                           (C) if such Definitive Securities are being
                  transferred pursuant to an exemption from registration in
                  accordance with Rule 144 under the Securities Act, (i) a
                  certification to that effect and (ii) if the Company so
                  requests, an opinion of counsel or other evidence reasonably
                  satisfactory to it as to the compliance with the restrictions
                  set forth in the legend set forth in Section 2.3(d)(i).

                  (b) Restrictions on Transfer of a Definitive Security for a
Beneficial Interest in a Global Security. A Definitive Security may not be
exchanged for a beneficial interest in a Global Security except upon
satisfaction of the requirements set forth below. Upon receipt by the Trustee of
a Definitive Security, duly endorsed or accompanied by a written instrument of
transfer in form reasonably satisfactory to the Company and the Registrar or
co-registrar, together with:

                                      A-4
<PAGE>

                  (i) certification that such Definitive Security is being
         transferred (A) to a QIB in accordance with Rule 144A or (B) to an IAI
         that has furnished to the Trustee a signed letter; and

                  (ii) written instructions directing the Trustee to make, or to
         direct the Securities Custodian to make, an adjustment on its books and
         records with respect to such Global Security to reflect an increase in
         the aggregate principal amount of the Securities represented by the
         Global Security, such instructions to contain information regarding the
         Depositary account to be credited with such increase,

then the Trustee shall cancel such Definitive Security and cause, or direct the
Securities Custodian to cause, in accordance with the standing instructions and
procedures existing between the Depository and the Securities Custodian, the
aggregate principal amount of Securities represented by the Global Security to
be increased by the aggregate principal amount of the Definitive Security to be
exchanged and shall credit or cause to be credited to the account of the Person
specified in such instructions a beneficial interest in the Global Security
equal to the principal amount of the Definitive Security so canceled. If no
Global Securities are then outstanding and the Global Security has not been
previously exchanged pursuant to Section 2.4, the Company shall issue and the
Trustee shall authenticate, upon written order of the Company in the form of an
Officers' Certificate, a new Global Security in the appropriate principal
amount.

                  (c) Transfer and Exchange of Global Securities. (i) The
transfer and exchange of Global Securities or beneficial interests therein shall
be effected through the Depository, in accordance with this Indenture (including
applicable restrictions on transfer set forth herein, if any) and the procedures
of the Depository therefor. A transferor of a beneficial interest in a Global
Security shall deliver a written order given in accordance with the Depository's
procedures containing information regarding the participant account of the
Depository to be credited with a beneficial interest in the Global Security and
such account shall be credited in accordance with such instructions with a
beneficial interest in the Global Security and the account of the Person making
the transfer shall be debited by an amount equal to the beneficial interest in
the Global Security being transferred. In the case of a transfer of a beneficial
interest in a Global Security to an IAI, the transferee must furnish a signed
letter to the Trustee containing certain representations and agreements (the
form of which letter can be obtained from the Trustee or the Company).

                  (ii) If the proposed transfer is a transfer of a beneficial
         interest in one Global Security to a beneficial interest in another
         Global Security, the Registrar shall reflect on its books and records
         the date and an increase in the principal amount of the Global Security
         to which such interest is being transferred in an amount equal to the
         principal amount of the interest to be so transferred, and the
         Registrar shall reflect on its books and records the date and a
         corresponding decrease in the principal amount of Global Security from
         which such interest is being transferred.

                  (iii) Notwithstanding any other provisions of this Appendix A
         (other than the provisions set forth in Section 2.4), a Global Security
         may not be transferred as a whole except by the Depository to a nominee
         of the Depository or by a nominee of the Depository to the Depository
         or another nominee of the Depository or by the Depository or any such
         nominee to a successor Depository or a nominee of such successor
         Depository.

                                      A-5
<PAGE>

                  (iv) In the event that a Global Security is exchanged for
         Securities in definitive registered form pursuant to Section 2.4 prior
         to the consummation of a Registered Exchange Offer or the effectiveness
         of a Shelf Registration Statement with respect to such Securities, such
         Securities may be exchanged only in accordance with such procedures as
         are substantially consistent with the provisions of this Section 2.3
         (including the certification requirements set forth on the reverse of
         the Initial Securities intended to ensure that such transfers comply
         with Rule 144A or such other applicable exemption from registration
         under the Securities Act, as the case may be) and such other procedures
         as may from time to time be adopted by the Company.

                  (d) Legend. (i) Except as permitted by the following
paragraphs (ii), (iii), (iv) and (vi), each Security certificate evidencing the
Global Securities and the Definitive Securities (and all Securities issued in
exchange therefor or in substitution thereof) shall bear a legend in
substantially the following form:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY STATE OR OTHER
JURISDICTION. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY
BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE

PURCHASING THIS SECURITY, AGREES FOR THE BENEFIT OF THE COMPANY ON ITS OWN
BEHALF AND ON BEHALF OF ANY INVESTOR ACCOUNT FOR WHICH IT HAS PURCHASED
SECURITIES THAT THIS SECURITY MAY NOT BE RESOLD, PLEDGED OR OTHERWISE
TRANSFERRED PRIOR TO THE SECOND ANNIVERSARY OF THE LATER OF THE DATE OF ISSUANCE

COMPANY, (2) SO LONG AS THIS SECURITY IS ELIGIBLE FOR RESALE PURSUANT TO RULE
144A UNDER THE SECURITIES ACT ("RULE 144A"), TO A PERSON WHOM THE SELLER
REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF
RULE 144A PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED
INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE RESALE, PLEDGE OR OTHER
TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A (AS INDICATED BY THE BOX CHECKED
BY THE TRANSFEROR ON THE CERTIFICATE OF TRANSFER ON THE REVERSE OF THIS
SECURITY), (3) TO AN INSTITUTION THAT IS AN "ACCREDITED INVESTOR" AS DEFINED IN
RULE 501(a)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT (AS INDICATED BY THE
BOX CHECKED BY THE TRANSFEROR ON THE CERTIFICATE OF TRANSFER ON THE REVERSE OF
THIS SECURITY) THAT IS ACQUIRING THIS SECURITY FOR ITS OWN ACCOUNT OR FOR THE
ACCOUNT OF ANOTHER INSTITUTIONAL ACCREDITED INVESTOR, IN EACH CASE, FOR
INVESTMENT PURPOSES AND NOT WITH A VIEW TO OR IN CONNECTION WITH

                                      A-6
<PAGE>

ANY DISTRIBUTION IN VIOLATION OF THE SECURITIES ACT, AND A CERTIFICATE (WHICH
MAY BE OBTAINED FROM THE COMPANY OR THE TRUSTEE) IS DELIVERED BY THE TRANSFEREE
TO THE COMPANY AND THE TRUSTEE, (4) PURSUANT TO AN EXEMPTION FROM THE
REGISTRATION REQUIREMENTS UNDER THE SECURITIES ACT PROVIDED BY RULE 144 (IF
APPLICABLE) UNDER THE SECURITIES ACT, OR (5) PURSUANT TO AN EFFECTIVE
REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH CASE IN ACCORDANCE WITH
ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE HOLDER
HEREOF, BY PURCHASING THIS SECURITY, REPRESENTS AND AGREES FOR THE BENEFIT OF
THE COMPANY THAT IT IS (1) A QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF
RULE 144A OR (2) AN INSTITUTION THAT IS AN "ACCREDITED INVESTOR" AS DEFINED IN
RULE 501(a)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT AND THAT IT IS HOLDING
THIS SECURITY FOR INVESTMENT PURPOSES AND NOT FOR DISTRIBUTION.

                  Each Definitive Security will also bear the following
additional legend:

         "IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE
         TRUSTEE, REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER
         INFORMATION INCLUDING, IN THE CASE OF CLAUSES (3) AND (4) ABOVE, AN
         OPINION OF COUNSEL AS ANY OF THEM MAY REASONABLY REQUIRE TO CONFIRM
         THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS."

                  (ii) Upon any sale or transfer of a Transfer Restricted
         Security (including any Transfer Restricted Security represented by a
         Global Security) pursuant to Rule 144 under the Securities Act:

                           (A) In the case of any Transfer Restricted Security
                  that is a Definitive Security, the Registrar shall permit the
                  Holder thereof to exchange such Transfer Restricted Security
                  for a Definitive Security that does not bear the legends set
                  forth above and rescind any restriction on the transfer of
                  such Transfer Restricted Security; and

                           (B) in the case of any Transfer Restricted Security
                  that is represented by a Global Security, the Registrar shall
                  permit the Holder thereof to exchange such Transfer Restricted
                  Security for a Definitive Security that does not bear the
                  legends set forth above and rescind any restriction on the
                  transfer of such Transfer Restricted Security,

in either case, if the Holder certifies in writing to the Registrar that its
request for such exchange was made in reliance on Rule 144 (such certification
to be in the form set forth on the reverse of the Initial Security).

                  (iii) After a transfer of any Initial Securities during the
         period of the effectiveness of a Shelf Registration Statement with
         respect to such Initial Securities, all requirements pertaining to
         legends on such Initial Security will cease to apply, the

                                      A-7
<PAGE>

         requirements requiring that any such Initial Security be issued in
         global form will cease to apply, and an Initial Security in
         certificated or global form without legends will be available to the
         transferee of the Holder of such Initial Securities upon exchange of
         such transferring Holder's certificated Initial Security. Upon the
         occurrence of any of the circumstances described in this paragraph, the
         Company will deliver an Officers' Certificate to the Trustee
         instructing the Trustee to issue Securities without legends.

                  (iv) Upon the consummation of a Registered Exchange Offer with
         respect to the Initial Securities pursuant to which certain Holders of
         such Initial Securities are offered Exchange Securities in exchange for
         their Initial Securities, all requirements pertaining to such Initial
         Securities that Initial Securities be issued in global form will cease
         to apply, and certificated Initial Securities with the restricted
         securities legend set forth in Exhibit 1 hereto will be available to
         Holders of such Initial Securities that do not exchange their Initial
         Securities, and Exchange Securities in certificated or global form will
         be available to Holders that exchange such Initial Securities in such
         Registered Exchange Offer. Upon the occurrence of any of the
         circumstances described in this paragraph, the Company will deliver an
         Officers' Certificate to the Trustee instructing the Trustee to issue
         Securities without legends.

                  (v) Upon the consummation of a Private Exchange with respect
         to the Initial Securities pursuant to which Holders of such Initial
         Securities are offered Private Exchange Securities in exchange for
         their Initial Securities, all requirements pertaining to such Initial
         Securities that Initial Securities issued to certain Holders be issued
         in global form will continue to apply, and Private Exchange Securities
         in global form will be available to Holders that exchange such Initial
         Securities in such Private Exchange.

                  (e) Cancelation or Adjustment of Global Security. At such time
as all beneficial interests in a Global Security have either been exchanged for
certificated or Definitive Securities, redeemed, repurchased or canceled, such
Global Security shall be returned by the Depository to the Trustee for
cancelation or retained and canceled by the Trustee. At any time prior to such
cancelation, if any beneficial interest in a Global Security is exchanged for
certificated or Definitive Securities, redeemed, repurchased or canceled, the
principal amount of Securities represented by such Global Security shall be
reduced and an adjustment shall be made on the books and records of the Trustee
(if it is then the Securities Custodian for such Global Security) with respect
to such Global Security, by the Trustee or the Securities Custodian, to reflect
such reduction.

                  (f) Obligations with Respect to Transfers and Exchanges of
Securities.

                  (i) To permit registrations of transfers and exchanges, the
         Company shall execute and the Trustee shall authenticate certificated
         Securities, Definitive Securities and Global Securities at the
         Registrar's or co-registrar's request.

                  (ii) No service charge shall be made for any registration of
         transfer or exchange, but the Company may require payment of a sum
         sufficient to cover any transfer tax, assessments, or similar
         governmental charge payable in connection therewith (other than any
         such transfer taxes, assessments or similar governmental charge payable
         upon exchange or transfer pursuant to Section 3.06, 4.06, 4.09 and
         9.05).

<PAGE>

                  (iii) The Registrar or co-registrar shall not be required to
         register the transfer of or exchange of any Security for a period
         beginning 15 days before the mailing of a notice of redemption or an
         offer to repurchase Securities or 15 days before an interest payment
         date.

                  (iv) Prior to the due presentation for registration of
         transfer of any Security, the Company, the Trustee, the Paying Agent,
         the Registrar or any co-registrar may deem and treat the person in
         whose name a Security is registered as the absolute owner of such
         Security for the purpose of receiving payment of principal of and
         interest on such Security and for all other purposes whatsoever,
         whether or not such Security is overdue, and none of the Company, the
         Trustee, the Paying Agent, the Registrar or any co-registrar shall be
         affected by notice to the contrary.

                  (v) All Securities issued upon any transfer or exchange
         pursuant to the terms of this Indenture shall evidence the same debt
         and shall be entitled to the same benefits under this Indenture as the
         Securities surrendered upon such transfer or exchange.

                  (g) No Obligation of the Trustee.

                  (i) The Trustee shall have no responsibility or obligation to
         any beneficial owner of a Global Security, a member of, or a
         participant in the Depository or any other Person with respect to the
         accuracy of the records of the Depository or its nominee or of any
         participant or member thereof, with respect to any ownership interest
         in the Securities or with respect to the delivery to any participant,
         member, beneficial owner or other Person (other than the Depository) of
         any notice (including any notice of redemption or repurchase) or the
         payment of any amount, under or with respect to such Securities. All
         notices and communications to be given to the Holders and all payments
         to be made to Holders under the Securities shall be given or made only
         to the registered Holders (which shall be the Depository or its nominee
         in the case of a Global Security). The rights of beneficial owners in
         any Global Security shall be exercised only through the Depository
         subject to the applicable rules and procedures of the Depository. The
         Trustee may rely and shall be fully protected in relying upon
         information furnished by the Depository with respect to its members,
         participants and any beneficial owners.

                  (ii) The Trustee shall have no obligation or duty to monitor,
         determine or inquire as to compliance with any restrictions on transfer
         imposed under this Indenture or under applicable law with respect to
         any transfer of any interest in any Security (including any transfers
         between or among Depository participants, members or beneficial owners
         in any Global Security) other than to require delivery of such
         certificates and other documentation or evidence as are expressly
         required by, and to do so if and when expressly required by, the terms
         of this Indenture, and to examine the same to determine substantial
         compliance as to form with the express requirements hereof.

                  (a) A Global Security deposited with the Depository or with
the Trustee as Securities Custodian pursuant to Section 2.1 shall be transferred

aggregate principal amount equal to the principal amount of such Global
Security, in exchange for such Global Security, only if such transfer complies
with Section 2.3 and (i) the Depository notifies the Company that it is
unwilling or unable to continue as a Depository for such Global Security or if
at any time the Depository ceases to be a "clearing agency" registered under the
Exchange Act, and a successor depositary is not appointed by the Company within
90 days of such notice, or (ii) an Event of Default has occurred and is
continuing or any event which after notice or lapse of time or both would be an
Event of Default has occurred or is continuing, or (iii) the Company, in its
sole discretion, notifies the Trustee in writing that it elects to cause the

owners thereof pursuant to this Section 2.4 shall be surrendered by the
Depository to the Trustee, to be so transferred, in whole or from time to time
in part, without charge, and the Trustee shall authenticate and deliver, upon
such transfer of each portion of such Global Security, an equal aggregate
principal amount of certificated Securities of authorized denominations. Any
portion of a Global Security transferred pursuant to this Section shall be
executed, authenticated and delivered only in denominations of $1,000 and any
integral multiple thereof and registered in such names as the Depository shall
direct. Any certificated Initial Security delivered in exchange for an interest
in the Global Security shall, except as otherwise provided by Section 2.3(d),
bear the restricted securities legend set forth in Exhibit 1 hereto.

                  (c) Subject to the provisions of Section 2.4(b), the
registered Holder of a 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.

                  (d) In the event of the occurrence of either of the events
specified in Section 2.4(a)(i), (ii) or (iii), the Company will promptly make
available to the Trustee a reasonable supply of certificated Securities in
definitive, fully registered form without interest coupons.

                       [FORM OF REVERSE SIDE OF SECURITY]

                    8 1/4% Senior Subordinated Note due 2011

1. Interest.

                  (a) Stone Energy Corporation, a Delaware corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Security at the rate per annum shown above. The Company
will pay interest semiannually in arrears on June 15 and December 15 of each
year. Interest on the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from December 10, 2001.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

                  (b) Special Interest. The holder of this Security is entitled
to the benefits of a Registration Rights Agreement, dated as of December 10,
2001, among the Company and the Initial Purchasers named therein (the
"Registration Rights Agreement"). Capitalized terms used in this paragraph (b)
but not defined herein have the meanings assigned to them in the Registration
Rights Agreement. In the event that (i) the Exchange Offer Registration
Statement has not been filed with the Commission on or prior to the 90th day
following the date of the original issuance of the Securities, (ii) neither the
Exchange Offer Registration Statement nor, if applicable, the Shelf Registration
Statement has been declared effective on or prior to the 180th day following the
date of the original issuance of the Securities, (iii) the Exchange Offer has
not been consummated on or prior to the 210th day following the date of the
original issuance of the Securities, or (iv) after the Shelf Registration
Statement, if applicable, has been declared effective, such Registration
Statement thereafter ceases to be effective or usable for more than 30
consecutive days in connection with resales of the Securities at any time that
the Company is obligated to maintain the effectiveness thereof pursuant to the
Registration Rights Agreement (each such event referred to in clauses (i)
through (iv) above being referred to herein as a "Registration Default"),
interest (the "Special Interest") shall accrue (in addition to stated interest
on the 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, at a rate per annum equal to 0.25% of the
principal amount of the Securities; provided, however, that such rate per annum
shall increase by 0.25% per annum from and including the 91st day after the
first such Registration Default (and each successive 91st day thereafter) unless
and until all Registration Defaults have been cured, upon which time the accrual
of Special Interest will cease and the interest rate will automatically and
immediately revert to the original interest rate; provided further, however,
that in no event shall the Special Interest accrue at a rate in excess of 1% per
annum. The Special Interest will be payable in cash semiannually in arrears each
June 15 and December 15

                                      E-5
<PAGE>

2. Method of Payment.

                  The Company will pay interest on the Securities (except
defaulted interest) to the Persons who are registered holders of Securities at
the close of business on the June 1 or December 1 next preceding the interest
payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United States of America that at the time of payment is legal
tender for payment of public and private debts. Payments in respect of the
Securities represented by a Global Security (including principal, premium, if
any, and interest) will be made by wire transfer of immediately available funds
to the accounts specified by The Depository Trust Company. The Company will make
all payments in respect of a certificated Security (including principal,
premium, if any, and interest), by mailing a check to the registered address of
each Holder thereof; provided, however, that payments on the Securities may also
be made, in the case of a Holder of at least $1,000,000 aggregate principal
amount of Securities, by wire transfer to a U.S. dollar account maintained by
the payee with a bank in the United States if such Holder elects payment by wire
transfer by giving written notice to the Trustee or the Paying Agent to such
effect designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in
its discretion).

3.  Paying Agent and Registrar.

                  Initially, JPMorgan Chase Bank (the "Trustee"), will act as
Paying Agent and Registrar. The Company may appoint and change any Paying Agent,
Registrar or co-registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or
co-registrar.

4.  Indenture.

                  The Company issued the Securities under an Indenture dated as
of December 10, 2001 (the "Indenture"), between the Company and the Trustee. The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
Sections 77aaa-77bbbb) as in effect on the date of the Indenture (the "TIA").
Terms defined in the Indenture and not defined herein have the meanings ascribed
thereto in the Indenture. The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the TIA for a statement of
those terms.

                  The Securities are general unsecured obligations of the
Company and may be issued in an unlimited aggregate principal amount at any one
time outstanding. [This Security is one of the Original Securities referred to
in the Indenture issued in an initial aggregate principal amount of
$200,000,000. The Securities include the Original Securities, an unlimited
aggregate principal amount of additional Initial Securities that may be issued
under the Indenture and any Exchange Securities issued in exchange for Initial
Securities. The Original Securities, such additional Initial Securities and the
Exchange Securities are treated as a single class of securities under the
Indenture.]* [This Security is one of an unlimited aggregate principal amount of
additional Initial Securities that may be issued under the Indenture. The
Securities include such additional Securities, the Original Securities in an
aggregate principal amount of $200,000,000 previously issued under the Indenture
and any Exchange Securities issued in exchange for Initial

Securities. The additional Initial Securities, the Original Securities and the
Exchange Securities are treated as a single class of securities under the
Indenture.]* The Indenture imposes certain limitations on the ability of the
Company and its Restricted Subsidiaries to, among other things, make certain
Investments and other Restricted Payments, pay dividends and other
distributions, incur Indebtedness, enter into consensual restrictions upon the
payment of certain dividends and distributions by such Restricted Subsidiaries,
enter into or permit certain transactions with Affiliates, create or incur Liens
and make Asset Sales. The Indenture also imposes limitations on the ability of
the Company or any Subsidiary Guarantor to consolidate or merge with or into any
other Person or convey, transfer or lease all or substantially all of the
Property of the Company or any Subsidiary Guarantor. Certain of the covenants
under the Indenture will be suspended or terminated as provided in the Indenture
if the Securities have achieved Investment Grade status.

                  To guarantee the due and punctual payment of the principal and
interest, if any, on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Subsidiary Guarantors, if any,
will unconditionally guarantee the Obligations on a senior subordinated basis
pursuant to the terms of the Indenture.

5. Optional Redemption.

                  The Securities are redeemable at any time before December 15,
2006, at the option of the Company, in whole but not in part, on not less than
30 nor more than 60 days' prior notice, at a cash redemption price equal to the
Make-Whole Amount, plus accrued and unpaid interest, if any, to the date of
redemption (subject to the right of Holders of record on the relevant record
date to receive interest due on the relevant interest payment date). The
Make-Whole Amount shall be certified in writing by an Officer of the Company to
the Trustee prior to consummating any such redemption.

                  The Securities are redeemable at any time on or after December
15, 2006, at the option of the Company, in whole or in part (equal to $1,000 in
principal amount or an integral multiple thereof), on or not less than 30 nor
more than 60 days' prior notice, at the following redemption prices (expressed
as percentages of principal amount), plus accrued and unpaid interest, if any,
to the date of redemption (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date), if redeemed during the 12-month period commencing on December 15 of the
years indicated below:

<PAGE>

                  Notwithstanding the foregoing, prior to December 15, 2004, the
Company may, at any time or from time to time, redeem up to 35% of the aggregate
principal amount of Securities issued under the Indenture at a redemption price
of 108.25% of the principal amount thereof plus accrued and unpaid interest, if
any, to the redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date) with the net proceeds of one or more Equity Offerings of the Company,
provided that at least 65% of the aggregate principal amount of the Securities
issued under the Indenture 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. The
redemption shall be made in accordance with procedures set forth in the
Indenture.

6. Sinking Fund.

                  The Securities are not subject to any sinking fund.

7. Notice of Redemption.

                  Notice of redemption will be mailed by first-class mail at
least 30 days but not more than 60 days before the redemption date to each
Holder of Securities to be redeemed at his or her registered address. Securities
in denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000. If money sufficient to pay the redemption price of and
accrued interest on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date interest
ceases to accrue on such Securities (or such portions thereof) called for
redemption.

8. Subordination.

                  The Securities are subordinated to Senior Indebtedness of the
Company. To the extent provided in the Indenture, Senior Indebtedness of the
Company must be paid before the Securities may be paid. In addition, any
Subsidiary Guaranty is subordinated to Senior Indebtedness of the relevant
Subsidiary Guarantor. The Company and each Subsidiary Guarantor, if any, agrees,
and each Securityholder by accepting a Security agrees, to the subordination
provisions contained in the Indenture and authorizes the Trustee to give it
effect and appoints the Trustee as attorney-in-fact for such purpose.

9. Repurchase of Securities at the Option of Holders upon Change of Control.

                  Upon a Change of Control, any Holder of Securities will have
the right, subject to certain conditions specified in the Indenture, to cause
the Company to repurchase all or any part of the Securities of such Holder at a
purchase price equal to 101% of the principal amount of the Securities to be
repurchased plus accrued and unpaid interest, if any, to the date of purchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date) as provided in, and
subject to the terms of, the Indenture.

10. Denominations; Transfer; Exchange.

                  The Securities are in registered form without coupons in
denominations of $1,000 and whole multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. Upon any transfer or
exchange, the Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements or transfer documents and to pay any
taxes required by law or permitted by the Indenture. The Registrar need not
register the transfer of or exchange any Securities selected for redemption
(except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or to transfer or exchange any Securities for a
period of 15 days prior to a selection of Securities to be redeemed or 15 days
before an interest payment date.

11. Persons Deemed Owners.

                  The registered Holder of this Security may be treated as the
owner of it for all purposes.

12. Unclaimed Money.

                  If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back to
the Company at its written request unless an abandoned property law designates
another Person. After any such payment, Holders entitled to the money must look
only to the Company and not to the Trustee for payment.

13. Discharge and Defeasance.

                  Subject to certain conditions, the Company at any time may
terminate some of or all of its obligations under the Securities and the
Indenture if the Company deposits with the Trustee money or U.S. Government
Obligations for the payment of principal and interest on the Securities to
redemption or maturity, as the case may be.

14. Amendment, Waiver.

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended without prior notice to any
Securityholder but with the written consent of the Holders of at least a
majority in aggregate principal amount of the outstanding Securities and (ii)
any default or noncompliance with any provision may be waived with the written
consent of the Holders of at least a majority in principal amount of the
outstanding Securities. Subject to certain exceptions set forth in the
Indenture, without the consent of any Holder of Securities, the Company, any
Subsidiary Guarantors and the Trustee may amend the Indenture or the Securities
(i) to cure any ambiguity, omission, defect or inconsistency; (ii) to comply
with Article 5 of the Indenture; (iii) to provide for uncertificated Securities
in addition to or in place of certificated Securities; (iv) to make certain
changes in the subordination provisions; (v) to add Subsidiary Guaranties with
respect to the Securities and to remove such Subsidiary Guaranties as provided
by the terms thereof; (vi) to secure the Securities; (vii) to add additional
covenants or to surrender rights and powers conferred on the Company; (viii) to
comply with the requirements of the Commission in order to effect or maintain
the qualification of the Indenture under the TIA; or (ix) to make any change
that does not adversely affect the rights of any Securityholder.

15. Defaults and Remedies.

                  If an Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of the Securities, subject to
certain limitations, may declare all the Securities to be immediately due and
payable. Certain events of bankruptcy or insolvency are Events of Default and
shall result in the Securities being immediately due and payable upon the
occurrence of such Events of Default without any further act of the Trustee or
any Holder.

                  Holders of Securities may not enforce the Indenture or the
Securities except as provided in the Indenture. The Trustee may refuse to
enforce the Indenture or the Securities unless it receives reasonable indemnity
or security. Subject to certain limitations, Holders of a majority in principal
amount of the Securities may direct the Trustee in its exercise of any trust or
power under the Indenture. The Holders of a majority in aggregate principal
amount of the Securities, by written notice to the Trustee and the Company, may
rescind any declaration of acceleration and its consequences if the rescission
would not conflict with any judgment or decree, and if all existing Events of
Default have been cured or waived except nonpayment of principal or interest
that has become due solely because of the acceleration.

16. Trustee Dealings with the Company.

                  Subject to certain limitations imposed by the TIA, the Trustee
under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its Affiliates with the same rights it would have if it were
not Trustee.

17. No Recourse Against Others.

                  A director, officer, employee or stockholder, as such, of the
Company or any Subsidiary Guarantor shall not have any liability for any
obligations of the Company under the Securities or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation. By accepting a Security, each Securityholder waives and releases all
such liability. The waiver and release are part of the consideration for the
issue of the Securities.

18. Authentication.

                  This Security shall not be valid until an authorized signatory
of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

19. Abbreviations.

                  Customary abbreviations may be used in the name of a
Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT
(=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship
and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to
Minors Act).

20. Governing Law.

                  THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK WITHOUT REFERENCE TO
PRINCIPLES OF CONFLICTS OF LAW THAT WOULD OTHERWISE REQUIRE THE APPLICATION OF
THE LAWS OF ANOTHER JURISDICTION.

21. CUSIP Numbers.

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

                  THE COMPANY WILL FURNISH TO ANY HOLDER OF SECURITIES UPON
WRITTEN REQUEST AND WITHOUT CHARGE TO THE HOLDER A COPY OF THE INDENTURE WHICH
HAS IN IT THE TEXT OF THIS SECURITY.

                   [FORM OF REVERSE SIDE OF EXCHANGE SECURITY]

                    8 1/4% Senior Subordinated Note due 2011

1. Interest.

                  Stone Energy Corporation, a Delaware corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Security at the rate per annum shown above. The Company
will pay interest semiannually in arrears on June 15 and December 15 of each
year. Interest on the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from December 10, 2001.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

2.  Method of Payment.

                  The Company will pay interest on the Securities (except
defaulted interest) to the Persons who are registered holders of Securities at
the close of business on the June 1 or December 1 next preceding the interest
payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United States of America that at the time of payment is legal
tender for payment of public and private debts. Payments in respect of the
Securities represented by a Global Security (including principal, premium, if
any, and interest) will be made by wire transfer of immediately available funds
to the accounts specified by The Depository Trust Company. The Company will make
all payments in respect of a certificated Security (including principal,
premium, if any, and interest), by mailing a check to the registered address of
each Holder thereof; provided, however, that payments on the Securities may also
be made, in the case of a Holder of at least $1,000,000 aggregate principal
amount of Securities, by wire transfer to a U.S. dollar account maintained by
the payee with a bank in the United States if such Holder elects payment by wire
transfer by giving written notice to the Trustee or the Paying Agent to such
effect designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in
its discretion).

3.  Paying Agent and Registrar.

                  Initially, JPMorgan Chase Bank (the "Trustee"), will act as
Paying Agent and Registrar. The Company may appoint and change any Paying Agent,
Registrar or co-registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or
co-registrar.

4.  Indenture.

                  The Company issued the Securities under an Indenture dated as
of December 10, 2001 (the "Indenture"), between the Company and the Trustee. The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the

                                      E-19
<PAGE>

Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) as in effect on
the date of the Indenture (the "TIA"). Terms defined in the Indenture and not
defined herein have the meanings ascribed thereto in the Indenture. The
Securities are subject to all such terms, and Securityholders are referred to
the Indenture and the TIA for a statement of those terms.

                  The Securities are general unsecured obligations of the
Company that may be issued in an unlimited aggregate principal amount at any one
time outstanding. This Security is one of the Exchange Securities referred to in
the Indenture issued in exchange for Initial Securities. The Securities include
the Exchange Securities, the Original Securities in the aggregate principal
amount of $200,000,000 and an unlimited aggregate principal amount of additional
Initial or Exchange Securities, as the case may be. The Exchange Securities, the
Original Securities and such additional Initial or Exchange Securities are
treated as a single class of securities under the Indenture. The Indenture
imposes certain limitations on the ability of the Company and its Restricted
Subsidiaries to, among other things, make certain Investments and other
Restricted Payments, pay dividends and other distributions, incur Indebtedness,
enter into consensual restrictions upon the payment of certain dividends and
distributions by such Restricted Subsidiaries, enter into or permit certain
transactions with Affiliates, create or incur Liens and make Asset Sales. The
Indenture also imposes limitations on the ability of the Company or any
Subsidiary Guarantor to consolidate or merge with or into any other Person or
convey, transfer or lease all or substantially all of the Property of the
Company or any Subsidiary Guarantor. Certain of the covenants under the
Indenture will be suspended or terminated as provided in the Indenture if the
Securities have achieved Investment Grade status.

                  To guarantee the due and punctual payment of the principal and
interest, if any, on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Subsidiary Guarantors, if any,
will unconditionally guarantee the Obligations on a senior subordinated basis
pursuant to the terms of the Indenture.

5.  Optional Redemption.

                  The Securities are redeemable at any time before December 15,

<S>                                                                              <C>
2006.................................................................            104.125%
2007.................................................................            102.750%
2008.................................................................            101.375%
2009 and thereafter..................................................            100.000%
</Table>

                  Notwithstanding the foregoing, prior to December 15, 2004, the
Company may, at any time or from time to time, redeem up to 35% of the aggregate
principal amount of Securities issued under the Indenture at a redemption price
of 108.25% of the principal amount thereof plus accrued and unpaid interest, if
any, to the redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date) with the net proceeds of one or more Equity Offerings of the Company,
provided that at least 65% of the aggregate principal amount of the Securities
issued under the Indenture 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. The
redemption shall be made in accordance with procedures set forth the Indenture.

6.  Sinking Fund.

                  The Securities are not subject to any sinking fund.

7.  Notice of Redemption.

                  Notice of redemption will be mailed by first-class mail at
least 30 days but not more than 60 days before the redemption date to each
Holder of Securities to be redeemed at his or her registered address. Securities
in denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000. If money sufficient to pay the redemption price of and
accrued interest on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date interest
ceases to accrue on such Securities (or such portions thereof) called for
redemption.

8.  Subordination.

                  The Securities are subordinated to Senior Indebtedness of the
Company. To the extent provided in the Indenture, Senior Indebtedness of the
Company must be paid before the Securities may be paid. In addition, any
Subsidiary Guaranty is subordinated to Senior Indebtedness of the relevant
Subsidiary Guarantor. The Company and each Subsidiary Guarantor, if any, agrees,
and each Securityholder by accepting a Security agrees, to the subordination
provisions contained in the Indenture and authorizes the Trustee to give it
effect and appoints the Trustee as attorney-in-fact for such purpose.

                                      E-21

9.  Repurchase of Securities at the Option of Holders upon Change of Control.

                  Upon a Change of Control, any Holder of Securities will have
the right, subject to certain conditions specified in the Indenture, to cause
the Company to repurchase all or any part of the Securities of such Holder at a
purchase price equal to 101% of the principal amount of the Securities to be
repurchased plus accrued and unpaid interest, if any, to the date of purchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date) as provided in, and
subject to the terms of, the Indenture.

10.  Denominations; Transfer; Exchange.

                  The Securities are in registered form without coupons in
denominations of $1,000 and whole multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. Upon any transfer or
exchange, the Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements or transfer documents and to pay any
taxes required by law or permitted by the Indenture. The Registrar need not
register the transfer of or exchange any Securities selected for redemption
(except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or to transfer or exchange any Securities for a
period of 15 days prior to a selection of Securities to be redeemed or 15 days
before an interest payment date.

11.  Persons Deemed Owners.

                  The registered Holder of this Security may be treated as the
owner of it for all purposes.

12.  Unclaimed Money.

                  If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back to
the Company at its written request unless an abandoned property law designates
another Person. After any such payment, Holders entitled to the money must look
only to the Company and not to the Trustee for payment.

13.  Discharge and Defeasance.

                  Subject to certain conditions, the Company at any time may
terminate some of or all of its obligations under the Securities and the
Indenture if the Company deposits with the Trustee money or U.S. Government
Obligations for the payment of principal and interest on the Securities to
redemption or maturity, as the case may be.

14.  Amendment, Waiver.

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended without prior notice to any
Securityholder but with the written consent of the Holders of at least a
majority in aggregate principal amount of the outstanding Securities and (ii)
any default or noncompliance with any provision may be waived with the written
consent of the Holders of at least a majority in principal amount of the
outstanding Securities. Subject to certain exceptions set forth in the
Indenture, without the consent of any Holder of Securities, the Company, any
Subsidiary Guarantors and the Trustee may amend the Indenture or the Securities
(i) to cure any ambiguity, omission, defect or inconsistency; (ii) to

                                      E-22
<PAGE>

comply with Article 5 of the Indenture; (iii) to provide for uncertificated
Securities in addition to or in place of certificated Securities; (iv) to make
certain changes in the subordination provisions; (v) to add Subsidiary
Guaranties with respect to the Securities and to remove such Subsidiary
Guaranties as provided by the terms thereof; (vi) to secure the Securities;
(vii) to add additional covenants or to surrender rights and powers conferred on
the Company; (viii) to comply with the requirements of the Commission in order
to effect or maintain the qualification of the Indenture under the TIA; or (ix)
to make any change that does not adversely affect the rights of any
Securityholder.

15.  Defaults and Remedies.

                  If an Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of the Securities, subject to
certain limitations, may declare all the Securities to be immediately due and
payable. Certain events of bankruptcy or insolvency are Events of Default and
shall result in the Securities being immediately due and payable upon the
occurrence of such Events of Default without any further act of the Trustee or
any Holder.

                  Holders of Securities may not enforce the Indenture or the
Securities except as provided in the Indenture. The Trustee may refuse to
enforce the Indenture or the Securities unless it receives reasonable indemnity
or security. Subject to certain limitations, Holders of a majority in principal
amount of the Securities may direct the Trustee in its exercise of any trust or
power under the Indenture. The Holders of a majority in aggregate principal
amount of the Securities, by written notice to the Trustee and the Company, may
rescind any declaration of acceleration and its consequences if the rescission
would not conflict with any judgment or decree, and if all existing Events of
Default have been cured or waived except nonpayment of principal or interest
that has become due solely because of the acceleration.

16.  Trustee Dealings with the Company.

                  Subject to certain limitations imposed by the TIA, the Trustee
under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its Affiliates with the same rights it would have if it were
not Trustee.

17.  No Recourse Against Others.

                  A director, officer, employee or stockholder, as such, of the
Company or any Subsidiary Guarantor shall not have any liability for any
obligations of the Company under the Securities or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation. By accepting a Security, each Securityholder waives and releases all
such liability. The waiver and release are part of the consideration for the
issue of the Securities.

18.  Authentication.

                  This Security shall not be valid until an authorized signatory
of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

19.  Abbreviations.

                  Customary abbreviations may be used in the name of a
Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT

and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to
Minors Act).

20.  Governing Law.

                  THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REFERENCE TO
PRINCIPLES OF CONFLICTS OF LAW THAT WOULD OTHERWISE REQUIRE THE APPLICATION OF
THE LAWS OF ANOTHER JURISDICTION.

21.  CUSIP Numbers.

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

                  THE COMPANY WILL FURNISH TO ANY HOLDER OF SECURITIES UPON
WRITTEN REQUEST AND WITHOUT CHARGE TO THE HOLDER A COPY OF THE INDENTURE WHICH
HAS IN IT THE TEXT OF THIS SECURITY.

                  2.1 Exchange Offer. The Company shall, for the benefit of the
Holders, at the Company's cost, (A) prepare and, as soon as practicable but not
later than 90 days following the Closing Date, file with the SEC an Exchange
Offer Registration Statement on an appropriate form under the 1933 Act with
respect to a proposed Exchange Offer and the issuance and delivery to the
Holders, in exchange for the Registrable Securities (other than Private Exchange
Securities), of a like principal amount of Exchange Securities, (B) use its
commercially reasonable efforts to cause the Exchange Offer Registration
Statement to be declared effective under the 1933 Act within 180 days of the
Closing Date, (C) use its commercially reasonable efforts to keep the Exchange
Offer Registration Statement effective until the closing of the Exchange Offer
and (D) use its commercially reasonable efforts to cause the Exchange Offer to
be consummated not later than 210 days following the Closing Date. The Exchange
Securities will be issued under the Indenture. Upon the effectiveness of the
Exchange Offer Registration Statement, the Company shall promptly commence the
Exchange Offer, it being the objective of such Exchange Offer to enable each
Holder eligible and electing to exchange Registrable Securities for Exchange
Securities (assuming that such Holder (a) is not an affiliate of the Company
within the meaning of Rule 405 under the 1933 Act, (b) is not a broker-dealer
tendering Registrable Securities acquired directly from the Company for its own
account, (c) acquired or will acquire the Exchange Securities in the ordinary
course of such Holder's business and (d) has no arrangements or understandings
with any Person to participate in the Exchange Offer for the purpose of
distributing the Exchange Securities) to transfer such Exchange Securities from
and after their receipt without any limitations or restrictions under the 1933
Act and under state securities or blue sky laws.

                  In connection with the Exchange Offer, the Company shall:

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

                           (b) keep the Exchange Offer open for acceptance for a
period of not less than 20 business days after the date notice thereof is mailed
to the Holders (or longer if required by applicable law) (such period referred
to herein as the "Exchange Period");

                           (c) utilize the services of the Depositary for the
Exchange Offer;

                           (d) permit Holders to withdraw tendered Registrable
Securities at any time prior to 5:00 p.m. (Eastern Time), on the last business
day of the Exchange Period, pursuant to the instructions in the letter of
transmittal;

                           (e) notify each Holder that any Registrable Security
not tendered will remain outstanding and continue to accrue interest, but will
not retain any rights under this

<PAGE>

Agreement (except in the case of the Initial Purchasers and Participating
Broker-Dealers as provided herein); and

                           (f) otherwise comply in all respects with all
applicable laws relating to the Exchange Offer.

                  If, prior to consummation of the Exchange Offer, the Initial
Purchasers hold any Securities acquired by them and having the status of an
unsold allotment in the initial distribution, the Company upon the written
request of any Initial Purchaser shall, simultaneously with the delivery of the
Exchange Securities in the Exchange Offer, issue and deliver to such Initial
Purchaser in exchange (the "Private Exchange") for the Securities held by such
Initial Purchaser, a like principal amount of debt securities of the Company on
a senior subordinated basis, that are identical (except that such securities
shall bear appropriate transfer restrictions) to the Exchange Securities (the
"Private Exchange Securities").

                  The Exchange Securities and the Private Exchange Securities
shall be issued under (i) the Indenture or (ii) an indenture identical in all
material respects to the Indenture and which, in either case, has been qualified
under the Trust Indenture Act of 1939, as amended (the "TIA"), or is exempt from
such qualification and shall provide that the Exchange Securities shall not be
subject to the transfer restrictions set forth in the Indenture but that the
Private Exchange Securities shall be subject to such transfer restrictions. The
Indenture or such indenture shall provide that the Exchange Securities, the
Private Exchange Securities and the Securities shall vote and consent together
on all matters as one class and that none of the Exchange Securities, the
Private Exchange Securities or the Securities will have the right to vote or
consent as a separate class on any matter. The Private Exchange Securities shall
be of the same series as and the Company shall use all commercially reasonable
efforts to have the Private Exchange Securities bear the same CUSIP number as
the Exchange Securities.

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

                           (i) accept for exchange all Registrable Securities
                  duly tendered and not validly withdrawn pursuant to the
                  Exchange Offer in accordance with the terms of the Exchange
                  Offer Registration Statement and the letter of transmittal
                  which shall be an exhibit thereto;

                           (ii) accept for exchange all Securities properly
                  tendered pursuant to the Private Exchange;

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

                           (iv) cause the Trustee promptly to authenticate and
                  deliver Exchange Securities or Private Exchange Securities, as
                  the case may be, to each Holder of

<PAGE>

                  Registrable Securities so accepted for exchange in a principal
                  amount equal to the principal amount of the Registrable
                  Securities of such Holder so accepted for exchange.

                  Interest on each Exchange Security and Private Exchange
Security will accrue from the last date on which interest was paid on the
Registrable Securities surrendered in exchange therefor or, if no interest has
been paid on the Registrable Securities, from the date of original issuance. The
Exchange Offer and the Private Exchange shall not be subject to any conditions,
other than (i) that the Exchange Offer or the Private Exchange, or the making of
any exchange by a Holder, does not violate applicable law or any applicable
interpretation of the staff of the SEC, (ii) the due tendering of Registrable
Securities in accordance with the Exchange Offer and the Private Exchange, (iii)
that each Holder of Registrable Securities exchanged in the Exchange Offer shall
have represented that: (A) it is not an affiliate (as defined in Rule 405 under
the 1933 Act) of the Company; (B) all Exchange Securities to be received by it
shall be acquired in the ordinary course of its business; (C) at the time of the
consummation of the Exchange Offer it shall have no arrangement or understanding
with any person to participate in the distribution (within the meaning of the
1933 Act) of the Exchange Securities; and (D) if such Holder is a Participating
Broker-Dealer, it will receive Exchange Securities for its own account in
exchange for Registrable Securities that were acquired as a result of
market-making activities or other trading activities and that it will deliver a
prospectus in connection with any resale of such Exchange Securities; and such
Holder shall have made such other representations as may be reasonably necessary
under applicable SEC rules, regulations or interpretations to render the use of
Form S-4 or other appropriate form under the 1933 Act available and (iv) that no
action or proceeding shall have been instituted or threatened in any court or by
or before any governmental agency with respect to the Exchange Offer or the
Private Exchange which, in the Company's judgment, would reasonably be expected
to impair the ability of the Company to proceed with the Exchange Offer or the
Private Exchange. The Company shall inform the Initial Purchasers of the names
and addresses of the Holders to whom the Exchange Offer is made, and the Initial
Purchasers shall have the right to contact such Holders and otherwise facilitate
the tender of Registrable Securities in the Exchange Offer.

                  2.2 Shelf Registration. (i) If, because of any changes in law,
SEC rules or regulations or applicable interpretations thereof by the staff of
the SEC, the Company is not permitted to effect the Exchange Offer as
contemplated by Section 2.1 hereof, (ii) if for any other reason the Exchange
Offer Registration Statement is not declared effective within 180 days following
the original issue of the Registrable Securities or the Exchange Offer is not
consummated within 210 days after the original issue of the Registrable
Securities, (iii) upon the request of any of the Initial Purchasers with respect
to Registrable Securities held by such Initial Purchaser that are not eligible
to be exchanged for Exchange Securities in the Exchange Offer or (iv) if a
Holder is not permitted by applicable law to participate in the Exchange Offer
or elects to participate in the Exchange Offer but does not receive fully
tradeable Exchange Securities pursuant to the Exchange Offer, then in case of
each of clauses (i) through (iv) the Company shall, at its cost:

<PAGE>

                           (a) As promptly as practicable, file with the SEC,
                  and thereafter shall use its commercially reasonable efforts
                  to cause to be declared effective as promptly as practicable
                  but no later than 180 days after the original issue of the
                  Registrable Securities, a Shelf Registration Statement
                  relating to the offer and sale of the Registrable Securities
                  by the Holders from time to time in accordance with the
                  methods of distribution elected by the Majority Holders
                  participating in the Shelf Registration and set forth in such
                  Shelf Registration Statement.

                           (b) Use its commercially reasonable 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 from the date of
                  the original issue of the Securities, or for such shorter
                  period that will terminate when all Registrable Securities
                  covered by the Shelf Registration Statement have been sold
                  pursuant to the Shelf Registration Statement or cease to be
                  outstanding or otherwise to be Registrable Securities (the
                  "Effectiveness Period"); provided, however, that the
                  Effectiveness Period in respect of the Shelf Registration
                  Statement shall be extended to the extent required to permit
                  dealers to comply with the applicable prospectus delivery
                  requirements under the 1933 Act and as otherwise provided
                  herein.

                           (c) Notwithstanding any other provisions hereof, use
                  its commercially reasonable efforts to ensure that (i) any
                  Shelf Registration Statement and any amendment thereto and any
                  Prospectus forming part thereof and any supplement thereto
                  complies in all material respects with the 1933 Act and the
                  rules and regulations thereunder, (ii) any Shelf 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 Shelf Registration
                  Statement, and any supplement to such Prospectus (as amended
                  or supplemented from time to time), does not include an untrue
                  statement of a material fact or omit to state a material fact
                  necessary in order to make the statements therein, in light of
                  the circumstances under which they were made, not misleading.

                  The Company shall not permit any securities other than
Registrable Securities to be included in the Shelf Registration Statement. The
Company further agrees, if necessary, to supplement or amend the Shelf
Registration Statement, as required by Section 3(b) below, and to furnish to the
Holders of Registrable Securities copies of any such supplement or amendment
promptly after its being used or filed with the SEC. Notwithstanding the
foregoing, this Section 2.2 shall not apply if the Company determines, in its
reasonable judgment, upon advice of counsel, that the continued effectiveness
and usability of such Registration Statement would (i) require the disclosure of
material information, which the Company has a bona fide business reason for
preserving as confidential, or (ii) interfere with any financing, acquisition,
corporate reorganization or other material transaction involving the Company or
any of its Affiliates (as

<PAGE>

defined in the rules and regulations adopted under the Exchange Act); provided,
however, that the failure to keep the Registration Statement effective and
usable for offer and sales of Registrable Securities for such reasons shall last
no longer than 30 days in any 12-month period (whereafter Additional Interest
(pursuant to Section 2.5) shall accrue and be payable), so long as the Company
promptly thereafter complies with the requirements of Section 3(j) hereof, if
applicable. Any such period during which the Company fails to keep the
Registration Statement effective and usable for offers and sales of Registrable
Securities is referred to as a "Suspension Period." A Suspension Period shall
commence on and include the date that the Company gives notice that the
Registration Statement is no longer effective or the Prospectus included therein
is no longer usable for offers and sales of Registrable Securities and shall end
on the earlier to occur of (i) date when each seller of Registrable Securities
covered by such Registration Statement either receives the copies of the
supplemented or amended Prospectus contemplated by Section 3(j) hereof or is
advised in writing by the Company that use of the Prospectus may be resumed and
(ii) the expiration of the 30 days in any 12-month period during which one or
more Suspension Periods has been in effect.

                  2.3 Expenses. The Company shall pay all Registration Expenses
in connection with the registration pursuant to Section 2.1 or 2.2. Each Holder
shall pay all underwriting discounts and commissions and transfer taxes, if any,
relating to the sale or disposition of such Holder's Registrable Securities
pursuant to the Shelf Registration Statement.

                  2.4. Effectiveness. An Exchange Offer Registration Statement
pursuant to Section 2.1 hereof or a Shelf Registration Statement pursuant to
Section 2.2 hereof will not be deemed to have become effective unless it has
been declared effective by the SEC; provided, however, that if, after it has
been declared effective, the offering of Registrable Securities pursuant to an
Exchange Offer Registration Statement or a Shelf Registration Statement is
interfered with by any stop order, injunction or other order or requirement of
the SEC or any other governmental agency or court, such Registration Statement
will be deemed not to have become effective during the period of such
interference, until the offering of Registrable Securities pursuant to such
Registration Statement may legally resume.

                  2.5 Interest. The Indenture executed in connection with the
Securities will provide that in the event that (a) the Exchange Offer
Registration Statement is not filed with the SEC on or prior to the 90th
calendar day following the date of original issue of the Securities, (b) the
Exchange Offer Registration Statement or a Shelf Registration Statement, if
applicable, has not been declared effective on or prior to the 180th calendar
day following the date of original issue of the Securities or (c) the Exchange
Offer is not consummated on or prior to the 210th calendar day following the
date of original issue of the Securities (each such event referred to in clauses
(a) through (c) above, a "Registration Default"), the interest rate borne by the
Securities shall be increased ("Additional Interest") by one-quarter of one
percent per annum upon the occurrence of each Registration Default, which rate
will increase by one quarter of one percent each 90-day period that such
Additional Interest continues to accrue under any such circumstance, provided
that the maximum aggregate increase in the interest rate will in no event

<PAGE>

exceed one percent (1%) per annum. Upon the cure of all Registration Defaults
the accrual of Additional Interest will cease and the interest rate will revert
to the original rate.

                  If the Shelf Registration Statement is declared effective but
thereafter becomes unusable by the Holders for any reason, for more than 30
consecutive days, then the interest rate borne by the Securities will be
increased by 0.25% per annum of the principal amount of the Securities for the
first 90-day period (or portion thereof) beginning on the 31st such date that
such Shelf Registration Statement ceases to be usable, which rate shall be
increased by an additional 0.25% per annum of the principal amount of the
Securities at the beginning of each subsequent 90-day period, provided that the
maximum aggregate increase in the interest rate will in no event exceed one
percent (1%) per annum. Any amounts payable under this paragraph shall also be
deemed "Additional Interest" for purposes of this Agreement. Upon the Shelf
Registration Statement once again becoming usable, the interest rate borne by
the Securities will be reduced to the original interest rate if the Company is
otherwise in compliance with this Agreement at such time. Additional Interest
shall be computed based on the actual number of days elapsed in each 90-day
period in which the Shelf Registration Statement is unusable.

                  The Company shall notify the Trustee within three business
days after each and every date on which an event occurs in respect of which
Additional Interest is required to be paid (an "Event Date"). Additional
Interest shall be paid by depositing with the Trustee, in trust, for the benefit
of the Holders of Registrable Securities, on or before the applicable semiannual
interest payment date, immediately available funds in sums sufficient to pay the
Additional Interest then due. The Additional Interest due shall be payable on
each interest payment date to the record Holder of Securities entitled to
receive the interest payment to be paid on such date as set forth in the
Indenture. Each obligation to pay Additional Interest shall be deemed to accrue
from and including the day following the applicable Event Date.

                  3.       Registration Procedures.

                  In connection with the obligations of the Company with respect

reasonably request, including financial statements and schedules, in order to
facilitate the public sale or other disposition of the Registrable Securities;
and (iii) hereby consent to the use of the Prospectus or any amendment or
supplement thereto by each of the selling Holders of Registrable Securities in
connection with the offering and sale of the Registrable Securities covered by
the Prospectus or any amendment or supplement thereto;

                  (d) use its commercially reasonable efforts to register or
qualify the Registrable Securities under all applicable state securities or
"blue sky" laws of such jurisdictions as any Holder of Registrable Securities
covered by a Registration Statement and each underwriter of an underwritten
offering of Registrable Securities shall reasonably request by the time the
applicable Registration Statement is declared effective by the SEC, and do any
and all other acts and things which may be reasonably necessary or advisable to
enable each such Holder and underwriter to consummate the disposition in each
such jurisdiction of such Registrable Securities owned by such Holder; provided,
however, that the Company shall not be required to (i) qualify as a foreign
corporation or as a dealer in securities in any jurisdiction where it would not
otherwise be required to qualify but for this Section 3(d), or (ii) take any
action which would subject it to general service of process or taxation in any
such jurisdiction where it is not then so subject;

                  (e) notify promptly each Holder of Registrable Securities
under a Shelf Registration or any Participating Broker-Dealer who has notified

covered thereby, the representations and warranties of the Company contained in
any underwriting agreement, securities sales agreement or other similar

material respects, (v) of the happening of any event or the discovery of any
facts during the period a Shelf Registration Statement is effective which makes
any statement made in such Registration Statement or the related Prospectus
untrue in any material respect or which requires the making of any changes in
such Registration Statement or Prospectus in order to make the statements
therein not misleading, (vi) of the receipt by the Company of any notification
with respect to the suspension of the qualification of the Registrable
Securities or the Exchange Securities, as the case may be, for sale in any
jurisdiction or the initiation or threatening of any proceeding for such purpose
and (vii) of any determination by the Company that a post-effective amendment to
such Registration Statement would be appropriate;

                  (f) in the case of the Exchange Offer Registration Statement
(i) include in the Exchange Offer Registration Statement a section entitled
"Plan of Distribution" which shall contain a summary statement of the positions
taken or policies made by the staff of the SEC with respect to the potential
"underwriter" status of any broker-dealer that holds Registrable Securities
acquired for its own account as a result of market-making activities or other
trading activities and that will be the beneficial owner (as defined in Rule
13d-3 under the Exchange Act) of Exchange Securities to be received by such
broker-dealer in the Exchange Offer, whether such positions or policies have
been publicly disseminated by the staff of the SEC or such positions or policies
represent the prevailing views of the staff of the SEC, including a statement
that any such broker-dealer who receives Exchange Securities for Registrable
Securities pursuant to the Exchange Offer may be deemed a statutory underwriter
and must deliver a prospectus meeting the requirements of the 1933 Act in
connection with any resale of such Exchange Securities, (ii) furnish to each
Participating Broker-Dealer who has delivered to the Company the notice referred
to in Section 3(e), without charge, as many copies of each Prospectus included

prospectus, and any amendment or supplement thereto, as such Participating
Broker-Dealer may reasonably request, (iii) hereby consent to the use of the
Prospectus forming part of the Exchange Offer Registration Statement or any
amendment or supplement thereto, by any Person subject to the prospectus
delivery requirements of the SEC, including all Participating Broker-Dealers, in
connection with the sale or transfer of the Exchange Securities covered by the
Prospectus or any amendment or supplement thereto, and (iv) include in the
transmittal letter or similar documentation to be executed by an exchange
offeree in order to participate in the Exchange Offer (x) the following
provision:

                  "If the exchange offeree is a broker-dealer holding
                  Registrable Securities acquired for its own account as a
                  result of market-making activities or other trading

<PAGE>

                  activities, it will deliver a prospectus meeting the
                  requirements of the 1933 Act in connection with any resale of
                  Exchange Securities received in respect of such Registrable
                  Securities pursuant to the Exchange Offer;" and

(y) a statement to the effect that by a broker-dealer making the acknowledgment
described in clause (x) and by delivering a Prospectus in connection with the
exchange of Registrable Securities, the broker-dealer will not be deemed to
admit that it is an underwriter within the meaning of the 1933 Act;

                  (g) make every reasonable effort to obtain the withdrawal of
any order suspending the effectiveness of a Registration Statement at the
earliest possible moment;

                  (h) in the case of a Shelf Registration, furnish to each
Holder of Registrable Securities and each underwriter, if any, without charge,
at least one conformed copy of each Registration Statement and any
post-effective amendment thereto, including financial statements and schedules
(without documents incorporated therein by reference and all exhibits thereto,
unless requested);

                  (i) in the case of a Shelf Registration, cooperate with the
selling Holders of Registrable Securities to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be sold and
not bearing any restrictive legends; and enable such Registrable Securities to
be in such denominations (consistent with the provisions of the Indenture) and
registered in such names as the selling Holders or the underwriters, if any, may
reasonably request at least three business days prior to the closing of any sale
of Registrable Securities;

                  (j) in the case of a Shelf Registration, upon the occurrence
of any event or the discovery of any facts, each as contemplated by Sections
3(e)(v) and 3(e)(vi) hereof, as promptly as practicable after the occurrence of
such an event, use its commercially reasonable efforts to prepare a supplement
or post-effective amendment to the Registration Statement or the related
Prospectus or any document incorporated therein by reference or file any other
required document so that, as thereafter delivered to the purchasers of the
Registrable Securities or Participating Broker-Dealers, such Prospectus will not
contain at the time of such delivery any untrue statement of a material fact or
omit to state a material fact necessary to make the statements therein, in light
of the circumstances under which they were made, not misleading or will remain
so qualified. At such time as such public disclosure is otherwise made or the
Company determines that such disclosure is not necessary, in each case to
correct any misstatement of a material fact or to include any omitted material
fact, the Company agrees promptly to notify each Holder of such determination
and to furnish each Holder such number of copies of the Prospectus as amended or
supplemented, as such Holder may reasonably request;

                  (k) obtain a CUSIP number for all Exchange Securities, Private
Exchange Securities or Registrable Securities, as the case may be, not later
than the effective date of a

<PAGE>

Registration Statement, and provide the Trustee with printed certificates for
the Exchange Securities, Private Exchange Securities or the Registrable
Securities, as the case may be, in a form eligible for deposit with the
Depositary;

                  (l) (i) cause the Indenture to be qualified under the Trust
Indenture Act of 1939 (the "TIA") in connection with the registration of the
Exchange Securities or Registrable Securities, as the case may be, (ii)
cooperate with the Trustee and the Holders to effect such changes to the
Indenture as may be required for the Indenture to be so qualified in accordance
with the terms of the TIA and (iii) execute, and use its commercially reasonable
efforts to cause the Trustee to execute, all documents as may be required to
effect such changes, and all other forms and documents required to be filed with
the SEC to enable the Indenture to be so qualified in a timely manner;

                  (m) in the case of a Shelf Registration, enter into agreements
(including underwriting agreements) and take all other customary and appropriate
actions in order to expedite or facilitate the disposition of such Registrable
Securities and in such connection whether or not an underwriting agreement is
entered into and whether or not the registration is an underwritten
registration:

                           (i) make such representations and warranties to the
                  Holders of such Registrable Securities and the underwriters,
                  if any, in form, substance and scope as are customarily made
                  by issuers to underwriters in similar underwritten offerings
                  as may be reasonably requested by them;

                           (ii) 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, and the holders of a majority
                  in principal amount of the Registrable Securities being sold)
                  addressed to each selling Holder and the underwriters, if any,
                  covering the matters customarily covered in opinions requested
                  in sales of securities or underwritten offerings and such
                  other matters as may be reasonably requested by such Holders
                  and underwriters;

                           (iii) obtain "cold comfort" letters and updates
                  thereof from the Company's independent certified public
                  accountants (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 are, or are required to be, included in the
                  Registration Statement) addressed to the underwriters, if any,
                  and use commercially reasonable efforts to have such letter
                  addressed to the selling Holders of Registrable Securities (to
                  the extent consistent with Statement on Auditing Standards No.
                  72 of the American Institute of Certified Public Accounts),
                  such letters to be in customary form and covering matters of
                  the type customarily covered in "cold comfort" letters to
                  underwriters in connection with similar underwritten
                  offerings;

<PAGE>

                           (iv) enter into a securities sales agreement with the
                  Holders and an agent of the Holders providing for, among other
                  things, the appointment of such agent for the selling Holders
                  for the purpose of soliciting purchases of Registrable
                  Securities, which agreement shall be in form, substance and
                  scope customary for similar offerings;

                           (v) if an underwriting agreement is entered into,
                  cause the same to set forth indemnification provisions and
                  procedures substantially equivalent to the indemnification
                  provisions and procedures set forth in Section 4 hereof with
                  respect to the underwriters and all other parties to be
                  indemnified pursuant to said Section or, at the request of any
                  underwriters, in the form customarily provided to such
                  underwriters in similar types of transactions; and

                           (vi) deliver such documents and certificates as may
                  be reasonably requested and as are customarily delivered in
                  similar offerings to the Holders of a majority in principal
                  amount of the Registrable Securities being sold and the
                  managing underwriters, if any.

The above shall be done at (i) the effectiveness of such Registration Statement
(and each post-effective amendment thereto) and (ii) each closing under any
underwriting or similar agreement as and to the extent required thereunder;

                  (n) in the case of a Shelf Registration or if a Prospectus is
required to be delivered by any Participating Broker-Dealer in the case of an
Exchange Offer, make available for inspection by representatives of the Holders
of the Registrable Securities, any underwriters participating in any disposition
pursuant to a Shelf Registration Statement, any Participating Broker-Dealer and
any counsel or accountant retained by any of the foregoing, all financial and
other records, pertinent corporate documents and properties of the Company
reasonably requested by any such persons, and cause the respective officers,
directors, employees, and any other agents of the Company to supply all
information reasonably requested by any such representative, underwriter,
special counsel or accountant in connection with a Registration Statement, and
make such representatives of the Company available for discussion of such
documents as shall be reasonably requested by the Initial Purchasers;

                  (o) in the case of a Shelf Registration, a reasonable time
prior to filing any Shelf Registration Statement, any Prospectus forming a part
thereof, any amendment to such Shelf Registration Statement or amendment or
supplement to such Prospectus, provide copies of such document to the Holders of
Registrable Securities, to the Initial Purchasers, to counsel for the Holders
and to the underwriter or underwriters of an underwritten offering of
Registrable Securities, if any, make such changes in any such document prior to
the filing thereof as the Initial Purchasers, the counsel to the Holders or the
underwriter or underwriters reasonably request and not file any such document in
a form to which the Majority Holders, the Initial Purchasers on behalf of the
Holders of Registrable Securities, counsel for the Holders of

<PAGE>

Registrable Securities or any underwriter shall not have previously been advised
and furnished a copy of or to which the Majority Holders, the Initial Purchasers
of behalf of the Holders of Registrable Securities, counsel to the Holders of
Registrable Securities or any underwriter shall reasonably object within two
business days after receipt thereof, and make the representatives of the Company
available for discussion of such document as shall be reasonably requested by
the Holders of Registrable Securities, the Initial Purchasers on behalf of such
Holders, counsel for the Holders of Registrable Securities or any underwriter
and provide copies of any comment letters received from the SEC or any other
request by the SEC or any state securities authority for amendments or
supplements to a Registration Statement and Prospectus or for additional
information.

                  (p) in the case of a Shelf Registration, use its commercially
reasonable efforts to cause all Registrable Securities to be listed on any
securities exchange on which similar debt securities issued by the Company are
then listed if requested by the Majority Holders, or if requested by the
underwriter or underwriters of an underwritten offering of Registrable
Securities, if any;

                  (q) in the case of a Shelf Registration, use its commercially
reasonable efforts to cause the Registrable Securities to be rated by the
appropriate rating agencies, if so requested by the Majority Holders, or if
requested by the underwriter or underwriters of an underwritten offering of
Registrable Securities, if any;

                  (r) otherwise comply with all applicable rules and regulations
of the SEC and make available to its security holders, as soon as reasonably
practicable, an earnings statement covering at least 12 months which shall
satisfy the provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder;
and

                  (s) cooperate and assist in any filings required to be made
with the NASD and, in the case of a Shelf Registration, in the performance of
any due diligence investigation by any underwriter and its counsel (including
any "qualified independent underwriter" that is required to be retained in
accordance with the rules and regulations of the NASD).

                  If following the date hereof there has been a change in SEC
policy with respect to exchange offers such as the Exchange Offer, such that in
the opinion of counsel to the Company or the Holders there is a substantial
question as to whether the Exchange Offer is permitted by applicable federal
law, the Company hereby agrees to seek a no-action letter or other favorable
decision from the SEC allowing the Company to consummate an Exchange Offer for
the Notes. The Company hereby agrees to pursue the issuance of such a decision
to the SEC staff level and diligently pursuing a resolution (which need not be
favorable) by the SEC staff.

                  In the case of a Shelf Registration Statement, the Company may
(as a condition to such Holder's participation in the Shelf Registration)
require each Holder of Registrable Securities to furnish to the Company such
information regarding the Holder and the proposed distribution by such Holder of
such Registrable Securities as the Company may from time to time reasonably
request in writing.
<PAGE>

                  In the case of a Shelf Registration Statement, each Holder
agrees that, upon receipt of any notice from the Company of the happening of any
event or the discovery of any facts, each of the kind described in Section
3(e)(v) hereof, such Holder will forthwith discontinue disposition of
Registrable Securities pursuant to a Registration Statement until such Holder's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 3(j) hereof, and, if so directed by the Company, such Holder will
deliver to the Company (at its expense) all copies in such Holder's possession,
other than copies in permanent files then in such Holder's possession, of the
Prospectus covering such Registrable Securities current at the time of receipt
of such notice.

                  If any of the Registrable Securities covered by any Shelf
Registration Statement are to be sold in an underwritten offering, the
underwriter or underwriters and manager or managers that will manage such
offering will be selected by the Majority Holders of such Registrable Securities
included in such offering and shall be acceptable to the Company. No Holder of
Registrable Securities may participate in any underwritten registration
hereunder unless such Holder (a) agrees to sell such Holder's Registrable
Securities on the basis provided in any underwriting arrangements approved by
the persons entitled hereunder to approve such arrangements and (b) completes
and executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents required under the terms of such underwriting
arrangements.

                  4.       Indemnification; Contribution.

                  (a) The Company agrees to indemnify and hold harmless the
Initial Purchasers, each Holder, each Participating Broker-Dealer, each Person
who participates as an underwriter (any such Person being an "Underwriter") and
each Person, if any, who controls any Holder or Underwriter within the meaning
of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

                           (i) against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         any Registration Statement (or any amendment or supplement thereto)
         pursuant to which Exchange Securities or Registrable Securities were
         registered under the 1933 Act, including all documents incorporated
         therein by reference, or the omission or alleged omission therefrom of
         a material fact required to be stated therein or necessary to make the
         statements therein not misleading, or arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         any Prospectus (or any amendment or supplement thereto) or the omission
         or alleged omission therefrom of a material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading;

                           (ii) against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, to the extent of the
         aggregate amount paid in settlement of any

<PAGE>

         litigation, or any investigation or proceeding by any governmental
         agency or body, commenced or threatened, or of any claim whatsoever
         based upon any such untrue statement or omission, or any such alleged
         untrue statement or omission; provided that (subject to Section 4(d)
         below) any such settlement is effected with the written consent of the
         Company; and

                           (iii) against any and all expense whatsoever, as
         incurred (including the fees and disbursements of counsel chosen by any
         indemnified party), reasonably incurred in investigating, preparing or
         defending against any litigation, or any investigation or proceeding by
         any governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission, to the extent that any such
         expense is not paid under subparagraph (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by the
Holder or Underwriter expressly for use in a Registration Statement (or any
amendment or supplement thereto) or any Prospectus (or any amendment or
supplement thereto); provided further, that the Company shall not be liable
under the indemnity agreement in this subsection (a) with respect to any
Registration Statement or Prospectus to the extent that any such loss, claim,
damage, liability or expense results from the fact that such Underwriter sold
Securities to a person as to whom there was not sent or given, at or prior to
the written confirmation of such sale, a copy of the effective Registration
Statement or final Prospectus, as then amended or supplemented, if the Company
has previously furnished copies thereof in sufficient quantity to such
Underwriter and sufficiently in advance of such confirmation of sale to allow
for distribution by such time and the loss, claim, damage, liability or expense
results from an untrue statement or omission of a material fact contained in or
omitted from the Registration Statement or Prospectus which was corrected in the
effective Registration Statement or final Prospectus, as then amended or
supplemented, and such correction would have cured the defect giving rise to
such loss, claim, damage, liability or expense.

                  (b) Each Holder severally, but not jointly, agrees to
indemnify and hold harmless the Company, the Initial Purchasers, each
Underwriter and the other selling Holders, and each of their respective
directors and officers, and each Person, if any, who controls the Company, the
Initial Purchasers, any Underwriter or any other selling Holder within the
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any
and all loss, liability, claim, damage and expense described in the indemnity
contained in Section 4(a) hereof, as incurred, but only with respect to untrue
statements or omissions, or alleged untrue statements or omissions, made in the
Shelf Registration Statement (or any amendment or supplement thereto) or any
Prospectus included therein (or any amendment or supplement thereto) in reliance
upon and in conformity with written information with respect to such Holder
furnished to the Company by such Holder expressly for use in the Shelf
Registration

<PAGE>

Statement (or any amendment or supplement thereto) or such Prospectus (or any
amendment or supplement thereto); provided, however, that no such Holder shall
be liable for any claims hereunder in excess of the amount of net proceeds
received by such Holder from the sale of Registrable Securities pursuant to such
Shelf Registration Statement.

                  (c) Each indemnified party shall give written notice as
promptly as reasonably practicable to each indemnifying party of any action or
proceeding commenced against it in respect of which indemnity may be sought
hereunder, but failure so to notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement. An 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 foregoing, the
indemnified party shall have the right to employ its own counsel in any such
action and the indemnifying party shall bear the reasonable fees and
disbursements of such separate counsel, which shall be reimbursed promptly after
receipt of a bill therefore, if: (i) the employment of such counsel shall have
been specifically authorized in writing by the indemnifying party, (ii) the
indemnifying party shall have failed to assume the defense and employ counsel to
represent the indemnified party within a reasonable time but no later than 7
days after notice of the institution of such action or (iii) the named parties
to any such action (including any impleaded parties) include both such
indemnified party and the indemnifying party and such indemnified party shall
have been advised by such counsel that there may be one or more legal defenses
available to it which are different from or additional to those available to the
indemnifying party. In no event shall the indemnifying parties be liable for
fees and expenses of more than one counsel (in addition to any local counsel),
which firm shall be designated in writing by the indemnified parties, separate
from their own counsel for all indemnified parties in connection with any one
action or separate but similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances. No indemnifying
party shall, without the prior written consent of the indemnified parties,
(which consent shall not be unreasonably withheld or delayed), settle or
compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution is being sought under this Section 4(e) hereof
(whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an
unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as to or an admission of fault, culpability or a failure to act by
or on behalf of any indemnified party. Except as provided below in Section 4(d),
no indemnified party shall, without the prior written consent of the
indemnifying parties (which consent shall not be unreasonably withheld or
delayed), settle or compromise or consent to the entry of any judgment with
respect to any litigation, or any

<PAGE>

investigation or proceeding by an governmental agency or body, commenced or
threatened, or any claim whatsoever in respect of which indemnification or
contribution is being sought under this Section 4 (whether or not the
indemnified parties are actual or potential parties thereto).

                  (d) If at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 4(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received written notice of the terms of such
settlement at least 30 days prior to such settlement being entered into and
(iii) such indemnifying party shall not have reimbursed such indemnified party
in accordance with such request for fees and expenses of counsel prior to the
date of such settlement.

                  (e) If the indemnification provided for in this Section 4 is
for any reason unavailable to or insufficient to hold harmless an indemnified
party in respect of any losses, liabilities, claims, damages or expenses
referred to therein, then each indemnifying party shall contribute to the
aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, in such proportion as is
appropriate to reflect the relative fault of the Company on the one hand and the
Holders and the Initial Purchasers on the other hand in connection with the
statements or omissions which resulted in such losses, liabilities, claims,
damages or expenses, as well as any other relevant equitable considerations.

         The relative fault of the Company on the one hand and the Holders and
the Initial Purchasers on the other hand shall be determined by reference to,
among other things, whether any such untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company, the Holders or the Initial Purchasers
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

         The Company, the Holders and the Initial Purchasers agree that it would
not be just and equitable if contribution pursuant to this Section 4 were
determined by pro rata allocation (even if the Initial Purchasers were treated
as one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to above in this
Section 4. The aggregate amount of losses, liabilities, claims, damages and
expenses incurred by an indemnified party and referred to above in this Section
4 shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

         Notwithstanding the provisions of this Section 4, no Initial Purchaser
shall be required to contribute any amount in excess of the amount by which the
total price at which the Securities sold by it were offered exceeds the amount
of any damages which such Initial Purchaser has

<PAGE>

otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.

         No Person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

         For purposes of this Section 4, each Person, if any, who controls an
Initial Purchaser or Holder within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as such
Initial Purchaser or Holder, and each director of the Company, and each Person,
if any, who controls the Company within the meaning of Section 15 of the 1933
Act or Section 20 of the 1934 Act shall have the same rights to contribution as
the Company. The Initial Purchasers' respective obligations to contribute
pursuant to this Section 7 are several in proportion to the principal amount of
Securities set forth opposite their respective names in Schedule A to the
Purchase Agreement and not joint.

                  5.       Miscellaneous.

                  5.1 Rule 144 and Rule 144A. For so long as the Company is
subject to the reporting requirements of Section 13 or 15 of the 1934 Act, the
Company covenants that it will file the reports required to be filed by it under
the 1933 Act and Section 13(a) or 15(d) of the 1934 Act and the rules and
regulations adopted by the SEC thereunder. If the Company ceases to be so
required to file such reports, the Company covenants that it will upon the
request of any Holder of Registrable Securities (a) make publicly available such
information as is necessary to permit sales pursuant to Rule 144 under the 1933
Act, and (b) deliver such information to a prospective purchaser as is necessary
to permit sales pursuant to Rule 144A under the 1933 Act and it will take such
further action as any Holder of Registrable Securities may reasonably request.
Upon the reasonable request of any Holder of Registrable Securities, the Company
will deliver to such Holder a written statement as to whether it has complied
with such reporting requirements.

                  5.2 No Inconsistent Agreements. The Company has not entered
into and the Company will not after the date of this Agreement enter into any
agreement which is inconsistent with the rights granted to the Holders of
Registrable Securities in this Agreement or otherwise conflicts with the
provisions hereof. The rights granted to the Holders hereunder do not and will
not for the term of this Agreement in any way conflict with the rights granted
to the holders of the Company's other issued and outstanding securities under
any such agreements.

                  5.3 Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of Holders
of at least a majority in aggregate principal amount of the outstanding
Registrable Securities affected by such amendment, modification, supplement,
waiver or departure.

<PAGE>

                  5.4 Notices. All notices and other communications provided for
or permitted hereunder shall be made in writing by hand delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (a) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 5.4, which address initially is the address set forth in the Purchase
Agreement with respect to the Initial Purchasers; and (b) if to the Company,
initially at the Company's address set forth in the Purchase Agreement, and
thereafter at such other address of which notice is given in accordance with the
provisions of this Section 5.4.

                  All such notices and communications shall be deemed to have
been duly given: at the time delivered by hand, if personally delivered; two
business days after being deposited in the mail, postage prepaid, if mailed;
when answered back, if telexed; when receipt is acknowledged, if telecopied; and
on the next business day if timely delivered to an air courier guaranteeing
overnight delivery.

                  Copies of all such notices, demands, or other communications
shall be concurrently delivered by the person giving the same to the Trustee
under the Indenture, at the address specified in such Indenture.

                  5.5 Successor and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors, assigns and transferees of each
of the parties, including, without limitation and without the need for an
express assignment, subsequent Holders; provided that nothing herein shall be
deemed to permit any assignment, transfer or other disposition of Registrable
Securities in violation of the terms of the Purchase Agreement or the Indenture.
If any transferee of any Holder shall acquire Registrable Securities, in any
manner, whether by operation of law or otherwise, such Registrable Securities
shall be held subject to all of the terms of this Agreement, and by taking and
holding such Registrable Securities such person shall be conclusively deemed to
have agreed to be bound by and to perform all of the terms and provisions of
this Agreement, including the restrictions on resale set forth in this Agreement
and, if applicable, the Purchase Agreement, and the Indenture, and such person
shall be entitled to receive the benefits hereof.

                  5.6 Third Party Beneficiaries. The Initial Purchasers (even if
the Initial Purchasers are not Holders of Registrable Securities) shall be third
party beneficiaries to the agreements made hereunder between the Company, on the
one hand, and the Holders, on the other hand, and shall have the right to
enforce such agreements directly to the extent they deem such enforcement
necessary or advisable to protect their rights or the rights of Holders
hereunder. Each Holder of Registrable Securities shall be a third party
beneficiary to the agreements made hereunder between the Company, on the one
hand, and the Initial Purchasers, on the other hand, and shall have the right to
enforce such agreements directly to the extent it deems such enforcement
necessary or advisable to protect its rights hereunder.

<PAGE>

                  5.7. Specific Enforcement. Without limiting the remedies
available to the Initial Purchasers and the Holders, the Company acknowledges
that any failure by the Company to comply with its obligations under Sections
2.1 and 2.2 hereof may result in material irreparable injury to the Initial
Purchasers or the Holders for which there is no adequate remedy at law, that it
would not be possible to measure damages for such injuries precisely and that,
in the event of any such failure, the Initial Purchasers or any Holder may
obtain such relief as may be required to specifically enforce the Company's
obligations under Sections 2.1 and 2.2 hereof.

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

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

                  5.10 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO
THE PRINCIPLES OF CONFLICT OF LAWS THEREOF TO THE EXTENT THAT APPLICATION
THEREOF WOULD PROVIDE FOR THE APPLICATION OF THE SUBSTANTIVE LAWS OF ANOTHER
JURISDICTION.

                  5.11 Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

                  5.12 Entire Agreement. This Agreement represents the entire
agreement among the parties hereto with respect to the subject matter hereof and
supercedes and replaces any and all prior agreements and understandings, whether
oral or written, with respect thereto.

<PAGE>

                  IN WITNESS WHEREOF, the parties have executed this Agreement
as of the date first written above.
