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 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 (subject to Section 6.01) conclusive in favor of
the Trustee and the Company, if made in the manner provided in this Section.

                                       9

                  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.

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

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

                  The Company may, in the circumstances permitted by the Trust
Indenture Act, set any day as the record date for the purpose of determining the
Holders of Outstanding Securities of any series entitled to give or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given or taken by Holders
of Securities of such series. With regard to any record date set pursuant to
this paragraph, the Holders of Outstanding Securities of the relevant series on
such record date (or their duly appointed agents), and only such Persons, shall
be entitled to give or take the relevant action, whether or not such Holders
remain Holders after such record date. With regard to any action that may be
given or taken hereunder only by Holders of a requisite principal amount of
Outstanding Securities of any series (or their duly appointed agents) and for
which a record date is set pursuant to this paragraph, the Company may, at its
option, set an expiration date after which no such action purported to be given
or taken by any Holder shall be effective hereunder unless given or taken on or
prior to such expiration date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date (or their duly
appointed agents). On or prior to any expiration date set pursuant to this
paragraph, the Company may, on one or more occasions at its option, extend such
date to any later date. Nothing in this paragraph shall prevent any Holder (or
any duly appointed agent thereof) from giving or taking, after any such
expiration date, any action identical to, or, at any time, contrary to or
different from, the action or purported action to which such expiration date
relates, in which event the Company may set a record date in respect thereof
pursuant to this paragraph. Nothing in this paragraph shall be construed to
render ineffective any action taken at any time by the Holders (or their duly
appointed agents) of the requisite principal amount of Outstanding Securities of
the relevant series on the date such action is so taken. Notwithstanding the
foregoing or the Trust Indenture Act, the Company shall not set a record date
for, and the provisions of this paragraph shall not apply with respect to, any
notice, declaration or direction referred to in the next paragraph.

                                       10

                  The Trustee may set any day as a record date for the purpose
of determining the Holders of Outstanding Securities of any series entitled to
join in the giving or making of (i) any Notice of Default, (ii) any declaration
of acceleration referred to in Section 5.02, if an Event of Default with respect
to Securities of such series has occurred and is continuing and the Trustee
shall not have given such a declaration to the Company, (iii) any request to
institute proceedings referred to in Section 5.07(2) or (iv) any direction
referred to in Section 5.12, in each case with respect to Securities of such
series. Promptly after any record date is set pursuant to this paragraph, the
Trustee shall notify the Company and the Holders of Outstanding Series of such
series of any such record date so fixed and the proposed action. The Holders of
Outstanding Securities of such series on such record date (or their duly
appointed agents), and only such Persons, shall be entitled to join in such
notice, declaration or direction, whether or not such Holders remain Holders
after such record date; provided that, unless such notice, declaration or
direction shall have become effective by virtue of Holders of the requisite
principal amount of Outstanding Securities of such series on such record date
(or their duly appointed agents) having joined therein on or prior to the 90th
day after such record date, such notice, declaration or direction shall
automatically and without any action by any Person be cancelled and of no
further effect. Nothing in this paragraph shall be construed to prevent a Holder
(or a duly appointed agent thereof) from giving, before or after the expiration
of such 90-day period, a notice, declaration or direction contrary to or
different from, or, after the expiration of such period, identical to, the
notice, declaration or direction to which such record date relates, in which
event a new record date in respect thereof shall be set pursuant to this
paragraph. Nothing in this paragraph shall be construed to render ineffective
any notice, declaration or direction of the type referred to in this paragraph
given at any time to the Trustee and the Company by Holders (or their duly
appointed agents) of the requisite principal amount of Outstanding Securities of
the relevant series on the date such notice, declaration or direction is so
given.

                  Without limiting the foregoing, a Holder entitled hereunder to
give or take any action hereunder with regard to any particular Security may do

Section 1.05 Notices, Etc., to Trustee, Company and Subsidiary Guarantors.

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

                  (1) the Trustee by any Holder or by the Company or any
         Subsidiary Guarantor shall be sufficient for every purpose hereunder if
         made, given, furnished or filed in writing (which may be via facsimile)
         to or with the Trustee at its Corporate Trust Office, or

                                       11

                  (2) the Company or any Subsidiary Guarantor by the Trustee or
         by any Holder shall be sufficient for every purpose hereunder (unless
         otherwise herein expressly provided) if in writing and mailed,
         first-class postage prepaid, to the Company addressed to it at the
         address of its principal office specified in the first paragraph of
         this instrument or at any other address previously furnished in writing

event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each Holder affected by such event, at his address as it appears in the Security
Register, not later than the latest date (if any), and not earlier than the
earliest date (if any), prescribed for the giving of such notice. In any case
where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders. Where this
Indenture provides for notice in any manner, such notice may be waived in
writing by the Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice. Waivers of
notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such
waiver.

                  In case by reason of the suspension of regular mail service or
by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

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

Section 2.03      Form of Reverse of Security.

                  This Security is one of a duly authorized issue of securities
of the Company (herein called the "Securities"), issued and to be issued in one
or more series under an Indenture, dated as of _______________ __, 2006 (herein
called the "Indenture"), among the Company, the Subsidiary Guarantors named
therein and JPMorgan Chase Bank, N.A., as Trustee (herein called the "Trustee",
which term includes any successor trustee under the Indenture), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Subsidiary Guarantors, the Trustee and the
Holders of the Securities and of the terms upon which the Securities and the
Subsidiary Guarantees endorsed thereon are, and are to be, authenticated and
delivered. This Security is one of the series designated on the face hereof [if
applicable insert --, limited in aggregate principal amount to $___________].

                  [If applicable, insert -- Subject to and upon compliance with
the provisions of the Indenture, the Holder of this Security is entitled, at his
option, at any time on or before the close of business on __________, or in case
this Security or a portion hereof is called for redemption, then in respect of
this Security or such portion hereof until and including, but (unless the
Company defaults in making the payment due upon redemption) not after, the close
of business on the 10th calendar day before the Redemption Date, to convert this
Security (or any portion of the principal amount hereof which is $1,000 or an
integral multiple thereof), at the principal amount hereof, or of such portion,
into fully paid and non-assessable shares (calculated as to each conversion to
the nearest 1/100 of a share) of Common Stock of the Company at a conversion
price per share of Common Stock equal to $_____ per each share of Common Stock
(or at the current adjusted conversion price if an adjustment has been made as
provided in the Indenture) by surrender of this Security, duly endorsed or
assigned to the Company or in blank, to the Company at its office or agency in
_________, accompanied by written notice to the Company that the Holder hereof
elects to convert this Security, or if less than the entire principal amount
hereof is to be converted, the portion hereof to be converted, and, in case such
surrender shall be made during the period from the close of business on any
Regular Record Date next preceding any Interest Payment Date to the opening of
business on such Interest Payment Date (unless this Security or the portion
thereof being converted has been called for redemption on a Redemption Date
within such period), also accompanied by payment in funds acceptable to the
Company of an amount equal to the interest payable on such Interest Payment Date
on the principal amount of this Security then being converted. Subject to the
aforesaid requirement for payment and, in the case of a conversion after the
Regular Record Date next preceding any Interest Payment Date and on or before
such Interest Payment Date, to the right of the Holder of this Security (or any
Predecessor Security) of record at such Regular Record Date to receive an
installment of interest (with certain exceptions provided in the Indenture), no
payment or adjustment is to be made on conversion for interest accrued hereon or
for dividends on the Common Stock issued on conversion. No fractions of shares
or scrip representing fractions of shares will be issued on conversion, but
instead of any fractional interest the Company shall pay a cash adjustment as
provided in the Indenture. The conversion price is subject to adjustment as


                                       17

provided in the Indenture. In addition, the Indenture provides that in case of
certain consolidations or mergers to which the Company is a party or the
transfer of substantially all of the assets of the Company, the Indenture shall
be amended, without the consent of any Holders of Securities, so that this
Security, if then outstanding, will be convertible thereafter, during the period
this Security shall be convertible as specified above, only into the kind and
amount of securities, cash and other property receivable upon the consolidation,
merger or transfer by a holder of the number of shares of Common Stock into
which this Security might have been converted immediately prior to such
consolidation, merger or transfer (assuming such holder of Common Stock failed
to exercise any rights of election and received per share the kind and amount
received per share by a plurality of non-electing shares).]

be made [if applicable, insert -- in the inverse order in which they become
due.]

                  [If the Security is subject to redemption of any kind, insert
- -- In the event of redemption or conversion of this Security in part only, a new

may be declared due and payable in the manner and with the effect provided in

payable and (ii) of interest on any overdue principal and overdue interest all
of the Company's obligations in respect of the payment of the principal of and
interest, if any, on the Securities of this series shall terminate.]

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the Subsidiary Guarantors and the rights of the
Holders of the Securities of each series to be affected under the Indenture at
any time by the Company, the Subsidiary Guarantors and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at

provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company or

the Holder of this Security shall not have the right to institute any proceeding

for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

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

Section 2.06 Form of Guarantee.

                                    GUARANTEE

                  For value received, each of the Subsidiary Guarantors listed
below hereby jointly and severally unconditionally guarantees to the Holder of
the Security upon which this Guarantee is endorsed, and to the Trustee for
itself and on behalf of such Holder, the due and punctual payment of the
principal of (and premium, if any) and interest on such Security when and as the
same shall become due and payable, whether at the Stated Maturity, by
acceleration, call for redemption, purchase or otherwise, according to the terms
thereof and of the Indenture referred to therein and all other obligations of
the Company under the Indenture. In case of the failure of the Company
punctually to make any such payment, each of the Subsidiary Guarantors hereby
jointly and severally agrees to cause such payment to be made punctually when
and as the same shall become due and payable, whether at the Stated Maturity or
by acceleration, call for redemption, purchase or otherwise, and as if such
payment were made by the Company.

                  Each of the Subsidiary Guarantors hereby jointly and severally
agrees that its obligations hereunder shall be unconditional, irrespective of
the validity, regularity or enforceability of such Security or the Indenture,
the absence of any action to enforce the same or any release or amendment or
waiver of any term of any other Guarantee of, or any consent to departure from
any requirement of any other Guarantee of all or of any of the Securities, the
election by the Trustee or any of the Holders in any proceeding under Chapter 11
of the Bankruptcy Code of the application of Section 1111(b)(2) of the
Bankruptcy Code, any borrowing or grant of a security interest by the Company,
as debtor-in-possession, under Section 364 of the Bankruptcy Code, the
disallowance, under Section 502 of the Bankruptcy Code, of all or any portion of
the claims of the Trustee or any of the Holders for payment of any of the
Securities, any waiver or consent by the Holder of such Security or by the
Trustee or either of them with respect to any provisions thereof or of the
Indenture, the obtaining of any judgment against the Company or any action to
enforce the same or any other circumstances which might otherwise constitute a
legal or equitable discharge or defense of a guarantor. Each of the Subsidiary


                                       23

Guarantors hereby waives the benefits of diligence, presentment, demand of
payment, any requirement that the Trustee or any of the Holders exhaust any
right or take any action against the Company or any other Person, filing of
claims with a court in the event of insolvency or bankruptcy of the Company, any
right to require a proceeding first against the Company, protest or notice with
respect to such Security or the Indebtedness evidenced thereby and all demands
whatsoever, and covenants that this Subsidiary Guarantee will not be discharged
except by complete performance of the obligations contained in such Security and
in this Subsidiary Guarantee. Each of the Subsidiary Guarantors hereby agrees
that, in the event of a default in payment of principal (or premium, if any) or
interest on such Security, whether at the Stated Maturity, by acceleration, call
for redemption, purchase or otherwise, legal proceedings may be instituted by
the Trustee on behalf of, or by, the Holder of such Security, subject to the
terms and conditions set forth in the Indenture, directly against each of the
Subsidiary Guarantors to enforce this Subsidiary Guarantee without first
proceeding against the Company. Each Subsidiary Guarantor agrees that if, after
the occurrence and during the continuance of an Event of Default, the Trustee or
any of the Holders are prevented by applicable law from exercising their
respective rights to accelerate the maturity of the Securities, to collect
interest on the Securities, or to enforce or exercise any other right or remedy
with respect to the Securities, such Subsidiary Guarantor agrees to pay to the
Trustee for the account of the Holders, upon demand therefor, the amount that
would otherwise have been due and payable had such rights and remedies been
permitted to be exercised by the Trustee or any of the Holders.

                  No reference herein to the Indenture and no provision of this
Subsidiary Guarantee or of the Indenture shall alter or impair the Subsidiary
Guarantee of any Subsidiary Guarantor, which is absolute and unconditional, of
the due and punctual payment of the principal (and premium, if any) and interest
on the Security upon which this Subsidiary Guarantee is endorsed.

                  Each Subsidiary Guarantor shall be subrogated to all rights of
the Holder of this Security against the Company in respect of any amounts paid
by such Subsidiary Guarantor on account of this Security pursuant to the
provisions of its Subsidiary Guarantee or the Indenture; provided, however, that
such Subsidiary Guarantor shall not be entitled to enforce or to receive any
payments arising out of, or based upon, such right of subrogation until the
principal of (and premium, if any) and interest on this Security and all other
Securities issued under the Indenture shall have been paid in full.

                  This Subsidiary Guarantee shall remain in full force and
effect and continue to be effective should any petition be filed by or against
the Company for liquidation or reorganization, should the Company become
insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any significant part of the
Company's assets, and shall, to the fullest extent permitted by law, continue to
be effective or be reinstated, as the case may be, if at any time payment and
performance of the Securities is, pursuant to applicable law, rescinded or
reduced in amount, or must otherwise be restored or returned by any obligee on
the Securities whether as a "voidable preference," "fraudulent transfer," or
otherwise, all as though such payment or performance had not been made. In the
event that any payment, or any part thereof, is rescinded, reduced, restored or
returned, the Securities shall, to the fullest extent permitted by law, be
reinstated and deemed reduced only by such amount paid and not so rescinded,
reduced, restored or returned.

                                       24

                  The Subsidiary Guarantors shall have the right to seek
contribution from any non-paying Subsidiary Guarantor so long as the exercise of
such right does not impair the rights of the Holders under this Subsidiary
Guarantee.

                  The Subsidiary Guarantors or any particular Subsidiary
Guarantor shall be released from this Subsidiary Guarantee upon the terms and
subject to certain conditions provided in the Indenture.

                  By delivery of a Supplemental Indenture to the Trustee in
accordance with the terms of the Indenture, each Person that becomes a
Subsidiary Guarantor after the date of the Indenture will be deemed to have
executed and delivered this Guarantee for the benefit of the Holder of this
Security with the same effect as if such Subsidiary Guarantor was named below.

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

                  This Subsidiary Guarantee shall not be valid or obligatory for
any purpose until the certificate of authentication on the Security upon which
this Subsidiary Guarantee is endorsed shall have been executed by the Trustee
under the Indenture by manual signature.

                  Reference is made to Article XIII of the Indenture for further
provisions with respect to this Subsidiary Guarantee.

                  THIS SUBSIDIARY GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

                  IN WITNESS WHEREOF, each of the Subsidiary Guarantors has
caused this Subsidiary Guarantee to be duly executed.

Securities") having terms and conditions identical to those of such series of

                           (i) may have a different issue date from such series
of Outstanding Securities;

                           (ii) may have a different amount of interest payable
on the first Interest Payment Date after issuance than is payable on such series
of Outstanding Securities; and

                           (iii) may have terms specified in such Board
Resolution for such Add On Securities making appropriate adjustments to this
Article III applicable to such Add On Securities in order to conform to and
ensure compliance with the Securities Act (or applicable securities laws) which
are not adverse in any material respect to the Holder of any Outstanding
Securities (other than such Add On Securities) and which shall not affect the
rights or duties of the Trustee.

                                       28

Section 3.02 Denominations.

                  The Securities of each series shall be issuable only in
registered form without coupons in such denominations as shall be specified as
contemplated by Section 3.01. In the absence of any such specified denomination
with respect to the Securities of any series, the Securities of such series
shall be issuable in denominations of $1,000 and any integral multiple thereof.

Section 3.03 Execution, Authentication, Delivery and Dating.

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

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

                  At any time 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 and having endorsed thereon the Subsidiary Guarantees
executed pursuant to Section 13.02 by the Subsidiary Guarantors to the Trustee
for authentication, together with a Company Order for the authentication and
delivery of such Securities with the Subsidiary Guarantees endorsed thereon, and
the Trustee in accordance with the Company Order shall authenticate and deliver
such Securities with the Subsidiary Guarantees endorsed thereon. If the form or
terms of the Securities of the series have been established in or pursuant to
one or more Board Resolutions as permitted by Sections 2.01 and 3.01, in
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
provided with, and (subject to Section 6.01) shall be fully protected in relying
upon, an Opinion of Counsel stating,

                  (1) if the form of such Securities has been established by or
         pursuant to Board Resolution as permitted by Section 2.01, that such
         form has been established in conformity with the provisions of this
         Indenture;

                  (2) if the terms of such Securities have been established by
         or pursuant to Board Resolution as permitted by Section 3.01, that such
         terms have been established in conformity with the provisions of this
         Indenture; and

                  (3) that such Securities, when authenticated and delivered by
         the Trustee and issued by the Company in the manner and subject to any
         conditions specified in such Opinion of Counsel, will constitute valid
         and legally binding obligations of the Company enforceable in
         accordance with their terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and similar laws of
         general applicability relating to or affecting creditors' rights and to
         general equity principles.

                                       29

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

                  Notwithstanding the provisions of Section 3.01 and of the
preceding paragraph, if all Securities of a series are not to be originally
issued at one time, it shall not be necessary to deliver the Officer's
Certificate otherwise required pursuant to Section 3.01 or the Company Order and
Opinion of Counsel otherwise required pursuant to such preceding paragraph at or
prior to the time of authentication of each Security of such series if such
documents are delivered at or prior to the authentication upon original issuance
of the first Security of such series to be issued.

                  Each Security shall be dated the date of its authentication.
No Security or Subsidiary Guarantee shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for
herein executed by the Trustee by manual signature, and such certificate upon
any Security shall be conclusive evidence, and the only evidence, that such
Security and the Subsidiary Guarantees endorsed thereon have been duly
authenticated and delivered hereunder. Notwithstanding the foregoing, if any
Security shall have been authenticated and delivered hereunder but never issued
and sold by the Company, and the Company shall deliver such Security to the
Trustee for cancellation as provided in Section 3.09, for all purposes of this
Indenture such Security shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits of this
Indenture.

Section 3.04 Temporary Securities.

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

                  If temporary Securities of any series are issued, the Company
will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such
series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Company in a Place of Payment for
that series, without charge to the Holder. Upon surrender for cancellation of
any one or more temporary Securities of any series the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
a like aggregate principal amount and having endorsed thereon Subsidiary
Guarantees of the same tenor executed by the Subsidiary Guarantors. Until so
exchanged, the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series and tenor.

                                       30

Section 3.05 Registration, Registration of Transfer and Exchange.

                  The Company shall cause to be kept at the Corporate Trust
Office of the Trustee a register (the register maintained in such office and in
any other office or agency of the Company in a Place of Payment being herein
sometimes collectively referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Company shall provide
for the registration of Securities and of transfers of Securities. The Trustee
is hereby appointed "Security Registrar" for the purpose of registering
Securities and transfers of Securities as herein provided.

                  Upon surrender for registration of transfer of any Security of
any series at the office or agency in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series, of any authorized denominations and of a like tenor and
aggregate principal amount, each such Security having endorsed thereon the
Subsidiary Guarantees executed by the Subsidiary Guarantors.

                  At the option of the Holder, Securities of any series may be
exchanged for other Securities of the same series, of any authorized
denominations and of a like tenor and aggregate principal amount, and having the
Subsidiary Guarantee endorsed thereon executed by each Subsidiary Guarantor,
upon surrender of the Securities to be exchanged at such office or agency.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, the Subsidiary Guarantors shall execute the Subsidiary Guarantees
endorsed on, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

                  All Securities and the Subsidiary Guarantees endorsed thereon
issued upon any registration of transfer or exchange of Securities shall be the
valid obligations of the Company and the respective Subsidiary Guarantors,
evidencing the same debt and Subsidiary Guarantees, and entitled to the same
benefits under this Indenture, as the Securities and Subsidiary Guarantees
surrendered upon such registration of transfer or exchange.

                  Every Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company or the Trustee) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

                  No service charge shall be made for any registration of
transfer or exchange of Securities, but the Company or Security Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of Securities, other than exchanges pursuant to Section 3.04, 9.06 or
11.07 not involving any transfer.

                                       31

                  The Company shall not be required (1) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of Securities of that series selected for redemption under Section
11.03 and ending at the close of business on the day of such mailing, or (2) to
register the transfer of or exchange any Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed
in part.

                  Notwithstanding any other provision in this Indenture, no
Global Security may be transferred to, or registered or exchanged for Securities
registered in the name of, any Person other than the Depositary for such Global
Security or any nominee thereof, and no such transfer may be registered, unless
(1) such Depositary (A) notifies the Company that it is unwilling or unable to
continue as Depositary for such Global Security or (B) has ceased to be a
clearing agency registered under the Exchange Act, (2) the Company executes and
delivers to the Trustee a Company Order that such Global Security shall be so
transferable, registrable and exchangeable, and such transfers shall be
registrable, (3) there shall have occurred and be continuing an Event of Default
with respect to the Securities evidenced by such Global Security or (4) there
shall exist such other circumstances, if any, as have been specified for this
purpose as contemplated by Section 3.01. Notwithstanding any other provision in
this Indenture, a Global Security to which the restriction set forth in the
preceding sentence shall have ceased to apply may be transferred only to, and
may be registered and exchanged for Securities registered only in the name or
names of, such Person or Persons as the Depositary for such Global Security
shall have directed and no transfer thereof other than such a transfer may be
registered.

                  Every Security authenticated and delivered upon registration
of transfer of, or in exchange for or in lieu of, a Global Security to which the
restriction set forth in the first sentence of the preceding paragraph shall
apply, whether pursuant to this Section, Section 3.04, 3.06, 9.06 or 11.07 or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
Global Security.

Section 3.06 Mutilated, Destroyed, Lost and Stolen Securities.

                  If any mutilated Security is surrendered to the Trustee, the
Company shall execute, the Subsidiary Guarantors shall execute the Subsidiary
Guarantees endorsed thereon, and the Trustee shall authenticate and deliver in
exchange therefor a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

                  If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of
them, each Subsidiary Guarantor and any agent of either of them harmless, then,
in the absence of notice to the Company or the Trustee that such Security has
been acquired by a protected purchaser, the Company shall execute and the
Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or
stolen Security, a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding and
having endorsed thereon the Subsidiary Guarantees executed by the Subsidiary
Guarantors.

                                       32

                  In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

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

                  Every new Security of any series issued pursuant to this
Section in exchange for any mutilated Security or in lieu of any destroyed, lost
or stolen Security shall constitute an original additional contractual
obligation of the Company and the respective Subsidiary Guarantors, whether or
not the mutilated, destroyed, lost or stolen Security shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that
series duly issued hereunder.

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

Section 3.07 Payment of Interest; Interest Rights Preserved.

                  Except as otherwise provided as contemplated by Section 3.01
with respect to any series of Securities, interest on any Security which is
payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name that Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest.

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

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities of such series
         (or their respective Predecessor Securities) are registered at the
         close of business on a Special Record Date for the payment of such
         Defaulted Interest, which shall be fixed in the following manner. The
         Company shall notify the Trustee in writing of the amount of Defaulted
         Interest proposed to be paid on each Security of such series and the
         date of the proposed payment, and at the same time the Company shall
         deposit with the Trustee an amount of money equal to the aggregate
         amount proposed to be paid in respect of such Defaulted Interest or
         shall make arrangements satisfactory to the Trustee for such deposit
         prior to the date of the proposed payment, such money when deposited to
         be held in trust for the benefit of the Persons entitled to such
         Defaulted Interest as in this Clause provided. Thereupon the Trustee
         shall fix a Special Record Date for the payment of such Defaulted
         Interest which shall be not more than 15 days and not less than 10 days


                                       33

         prior to the date of the proposed payment and not less than 10 days
         after the receipt by the Trustee of the notice of the proposed payment.
         The Trustee shall promptly notify the Company of such Special Record
         Date and, in the name and at the expense of the Company, shall cause
         notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor to be mailed, first-class postage prepaid,
         to each Holder of Securities of such series at his address as it
         appears in the Security Register, not less than 10 days prior to such
         Special Record Date. Notice of the proposed payment of such Defaulted
         Interest and the Special Record Date therefor having been so mailed,
         such Defaulted Interest shall be paid to the Persons in whose names the
         Securities of such series (or their respective Predecessor Securities)
         are registered at the close of business on such Special Record Date and
         shall no longer be payable pursuant to the following Clause (2).

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

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

                  Subject to the provisions of Section 15.02, in the case of any
Security which is converted after any Regular Record Date and on or prior to the
next succeeding Interest Payment Date, interest whose Stated Maturity is on such
Interest Payment Date shall be payable on such Interest Payment Date
notwithstanding such conversion, and such interest (whether or not punctually
paid or duly provided for) shall be paid to the Person in whose name that
Security (or one or more Predecessor Securities) is registered at the close of
business on such Regular Record Date. Except as otherwise expressly provided in
the immediately preceding sentence, in the case of any Security which is
converted, interest whose Stated Maturity is after the date of conversion of
such Security shall not be payable.

Section 3.08 Persons Deemed Owners.

                  Prior to due presentment of a Security for registration of
transfer, the Company, the Subsidiary Guarantors, the Trustee and any agent of
the Company, the Subsidiary Guarantors or the Trustee may treat the Person in
whose name such Security is registered as the owner of such Security for the
purpose of receiving payment of principal of and any premium and (subject to
Section 3.07) any interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company,
the Subsidiary Guarantors, the Trustee nor any agent of the Company, the
Subsidiary Guarantors or the Trustee shall be affected by notice to the
contrary.

                                       34

Section 3.09 Cancellation.

                  All Securities surrendered for payment, redemption,
registration of transfer or exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly cancelled by it. The Company
may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and may deliver to the Trustee (or to any
other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of by
the Trustee in its customary manner.

Section 3.10 Computation of Interest.

                  Except as otherwise specified as contemplated by Section 3.01
for Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

Section 3.11 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 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. The Company will promptly notify
the Trustee in writing of any changes in the "CUSIP" numbers.

                                   ARTICLE IV

                           SATISFACTION AND DISCHARGE

Section 4.01 Satisfaction and Discharge of Indenture.

                  This Indenture shall upon Company Request cease to be of
further effect (except as to any surviving rights of conversion, registration of
transfer or exchange of Securities herein expressly provided for), and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture, when

                  (1) either

                           (A) all Securities theretofore authenticated and
                  delivered (other than (i) Securities which have been
                  destroyed, lost or stolen and which have been replaced or paid
                  as provided in Section 3.06 and (ii) Securities for whose
                  payment money has theretofore been deposited in trust or
                  segregated and held in trust by the Company and thereafter
                  repaid to the Company or discharged from such trust) have been
                  delivered to the Trustee for cancellation; or

                                       35

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

                                    (i) have become due and payable, or

                                    (ii) will become due and payable at their
                           Stated Maturity within one year, or

                                    (iii) are to be called for redemption within
                           one year under arrangements satisfactory to the
                           Trustee for the giving of notice of redemption by the
                           Trustee in the name, and at the expense, of the
                           Company, and the Company and/or a Subsidiary
                           Guarantor, in the case of (i), (ii) or (iii) above,
                           has deposited or caused to be deposited with the
                           Trustee as trust funds in trust for the purpose an
                           amount sufficient to pay and discharge the entire
                           indebtedness on such Securities not theretofore
                           delivered to the Trustee for cancellation, for
                           principal and any premium and interest to the date of
                           such deposit (in the case of Securities which have
                           become due and payable) or to the Stated Maturity or
                           Redemption Date, as the case may be;

                  (2) the Company and/or a Subsidiary Guarantor has paid or
         caused to be paid all other sums payable hereunder by the Company and
         the Subsidiary Guarantors; and

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

                  Notwithstanding the satisfaction and discharge of this
Indenture, the obligations of the Company to the Trustee under Section 6.07,
and, if money shall have been deposited with the Trustee pursuant to subclause
(B) of Clause (1) of this Section, the obligations of the Trustee under Section
4.02, shall survive such satisfaction and discharge.

Section 4.02 Application of Trust Money.

                  All money deposited with the Trustee pursuant to Section 4.01
shall be held in trust and applied by it, in accordance with the provisions of
the Securities and this Indenture, to the payment, either directly or through
any Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal and any
premium and interest for whose payment such money has been deposited with the
Trustee.

                                   REMEDIES

Section 5.01 Events of Default.

                  "Event of Default", wherever used herein with respect to
Securities of any series, means any one of the following events (whatever the
reason for such Event of Default and whether it shall be voluntary or
involuntary or be 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):

                  (1) default in the payment of any interest upon any Security
         of that series when it becomes due and payable, and continuance of such
         default for a period of 30 days; or

                  (2) default in the payment of the principal of (or premium, if
         any, on) any Security of that series at its Maturity; or

                  (3) default in the deposit of any sinking fund payment, when
         and as due by the terms of a Security of that series; or

                  (4) default in the performance, or breach, of Section 8.01 or
         Section 8.02; or

                  (5) default in the performance, or breach, of any covenant or
         warranty of the Company in this Indenture (other than a covenant or
         warranty a default in whose performance or whose breach is elsewhere in
         this Section specifically dealt with or which has expressly been
         included in this Indenture solely for the benefit of series of
         Securities other than that series), and continuance of such default or
         breach for a period of 30 days after there has been given, by
         registered or certified mail, to the Company by the Trustee or to the
         Company and the Trustee by the Holders of at least 25% in principal
         amount of the Outstanding Securities of that series a written notice
         specifying such default or breach and requiring it to be remedied and
         stating that such notice is a "Notice of Default" hereunder; or

                  (6) the Company shall fail to pay any Indebtedness in excess
         of $50,000,000 owing by the Company, or any interest or premium
         thereon, when due (whether by scheduled maturity, required prepayment,
         acceleration, demand or otherwise), and such failure shall continue
         after the applicable grace period, if any, specified in the agreement
         or instrument relating to such Indebtedness, or the Company shall fail
         to perform any term, covenant or agreement on its part to be performed
         under any agreement or instrument evidencing or securing or relating to
         any such Indebtedness, if the effect of such failure in either case is
         that the maturity of such Indebtedness is duly accelerated, without
         such Indebtedness having been discharged or such acceleration having
         been rescinded or annulled, in each such case, within a period of 10
         days after there shall have been given, by registered or certified
         mail, to the Company by the Trustee or to the Company and the Trustee
         by Holders of at least 25% in principal amount of the Outstanding
         Securities of that series, a written notice specifying such default and
         requiring the Company to cause such Indebtedness to be discharged or
         cause such acceleration to be rescinded or annulled, as the case may


                                       37

         be, and stating that such notice is a "Notice of Default" hereunder
         (the Trustee shall not be deemed to have knowledge of a default under
         this subsection (6) unless it shall have actual knowledge thereof);
         provided, however, that, subject to the provisions of Sections 6.01 and
         6.05, the Trustee shall not be deemed to have knowledge of such failure
         to pay unless either (A) a Responsible Officer of the Trustee shall
         have actual knowledge of such failure to pay or (B) the Trustee shall
         have received written notice thereof from the Company, from any Holder,
         from the holder of any such Indebtedness or from the trustee
         thereunder; or

                  (7) the entry by a court having jurisdiction in the premises
         of (A) a decree or order for relief in respect of the Company or any
         Subsidiary Guarantor that is a Significant Subsidiary in an involuntary
         case or proceeding under any applicable Federal or State bankruptcy,
         insolvency, reorganization or other similar law or (B) a decree or
         order adjudging the Company or any Subsidiary Guarantor that is a

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

Section 5.02 Acceleration of Maturity; Rescission and Annulment.

                  If an Event of Default (other than an Event of Default
specified in Section 5.01(7) or 5.01(8)) with respect to Securities of any
series at the time Outstanding occurs and is continuing, then in every such case
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
any of the Securities of that series are Original Issue Discount Securities,
such portion of the principal amount of such Securities as may be specified in
the terms thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable. If an Event of Default
specified in Section 5.01(7) or 5.01(8) with respect to Securities of any series
at the time Outstanding occurs, the principal amount of all the Securities of
that series (or, in the case of any Security of that series which specifies an
amount to be due and payable thereon upon acceleration of the Maturity thereof,
such amount as may be specified by the terms thereof) shall automatically, and
without any declaration or other action on the part of the Trustee or any
Holder, become immediately due and payable.

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

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

                           (A) all overdue interest on all Securities of that
                  series,

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

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest at the rate or rates
                  prescribed therefor in such Securities, and

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

         and

                  (2) all Events of Default with respect to Securities of that
         series, other than the non-payment of the principal of Securities of
         that series which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 5.13.

                                       39

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

Section 5.03 Collection of Indebtedness and Suits for Enforcement by Trustee.

                  The Company covenants that if:

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

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

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

Section 5.04 Trustee May File Proofs of Claim.

                  In case of any judicial proceeding relative to the Company or
any Subsidiary Guarantor (or any other obligor upon the Securities), or any of
the property or creditors of the Company or any Subsidiary Guarantor (or any
other obligor upon the Securities), the Trustee shall be entitled and empowered,
by intervention in such proceeding or otherwise, to take any and all actions
authorized under the Trust Indenture Act in order to have claims of the Holders
and the Trustee allowed in any such proceeding. In particular, the Trustee shall
be authorized to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 6.07.

                                       40

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

Section 5.05 Trustee May Enforce Claims Without Possession of Securities.

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

Section 5.06 Application of Money Collected.

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

                  FIRST: To the payment of all amounts due the Trustee under
         Section 6.07;

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

                  THIRD: To the Company, or to the extent the Trustee collects
         any amount directly from any Subsidiary Guarantor, to the Subsidiary
         Guarantor.

Section 5.07 Limitation on Suits.

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

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

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

                                       41

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

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

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

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

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

                  Notwithstanding any other provision in this Indenture, the
Holder of any Security shall have the right, which is absolute and
unconditional, to receive payment of the principal of and any premium and
(subject to Section 3.07) interest on such Security on the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on the
Redemption Date) and to convert such Security in accordance with Article XV and
to institute suit for the enforcement of any such payment and right to convert,
and such rights shall not be impaired without the consent of such Holder.

Section 5.09 Restoration of Rights and Remedies.

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

Section 5.10 Rights and Remedies Cumulative.

                  Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 3.06, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

                                       42

Section 5.11 Delay or Omission Not Waiver.

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

Section 5.12 Control by Holders.

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

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

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

                  (3) subject to the provisions of Section 6.01, the Trustee
         shall have the right to decline to follow any such direction if the
         Trustee in good faith shall, by a Responsible Officer or Officers of
         the Trustee, determine, and the Trustee shall have received a legal
         opinion stating, that the proceedings so directed would involve the
         Trustee in personal liability.

Section 5.13 Waiver of Past Defaults.

                  Subject to Section 5.02, the Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may on
behalf of the Holders of all the Securities of such series waive any past
default hereunder with respect to such series and its consequences, except a
default

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

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

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

                                       43

Section 5.14 Undertaking for Costs.

                  In any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, a court may require any party litigant in
such suit to file an undertaking to pay the costs of such suit, and may assess
costs (including reasonable attorneys' fees and expenses) against any such party
litigant, in the manner and to the extent provided in the Trust Indenture Act;
provided that neither this Section nor the Trust Indenture Act shall apply to
any suit instituted by the Trustee, to any suit instituted by any Holders of the
Securities, or group of Holders of the Securities, holding in the aggregate more
than 10% of principal amount of the Outstanding Securities of any series, or to
any suit instituted by any Holder of the Outstanding Securities for the
enforcement of the payment of principal of or interest on any Outstanding
Securities held by such Holder, on or after the respective due dates expressed
in such Outstanding Securities, and provided, further, that neither this Section
nor the Trust Indenture Act shall be deemed to authorize any court to require
such an undertaking or to make such an assessment in any suit instituted by the
Company or any Subsidiary Guarantor or the Trustee or, if applicable, in any
suit for the enforcement of the right to convert any Security in accordance with
Article XV.

Section 5.15 Waiver of Usury, Stay or Extension Laws.

                  Each of the Company and each Subsidiary Guarantor covenants
(to the extent that it may lawfully do so) that it will not at any time insist
upon, or plead, or in any manner whatsoever claim or take the benefit or
advantage of, any usury, 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 each of the Company and each Subsidiary Guarantor (to the
extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law and covenants that it will not hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been enacted.

                                       44

                                   THE TRUSTEE

                  The Trustee hereby accepts the trust imposed upon it by this
Indenture and covenants and agrees to perform the same, as herein expressed.

Section 6.01 Duties of Trustee.

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

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

                  (1) The Trustee need perform only those duties as are
         specifically set forth in this Indenture and no others, and no
         covenants or obligations shall be implied in or read into this
         Indenture.

                  (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, in the case of any such certificates or
         opinions which by any provision hereof are specifically required to be
         furnished to the Trustee, the Trustee shall be under a duty to examine
         the same to determine whether or not they substantially conform to the
         requirements of this Indenture (but need not confirm or investigate the
         accuracy of mathematical calculations or other facts stated therein).

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

                  (1) This paragraph does not limit the effect of paragraph (b)
         of this Section 6.01.

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

                  (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 5.12.

                  (d) No provision of this Indenture shall require the Trustee
to expend or risk its own funds or otherwise incur any financial liability in
the performance of any of its duties hereunder or to take or omit to take any
action under this Indenture.

                  (e) Every provision of this Indenture that in any way relates
to the Trustee is subject to paragraphs (a), (b), (c), (d) and (f) of this
Section 6.01.

                                       45

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

Section 6.02 Rights of Trustee.

                  Subject to Section 6.01:

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

                  (b) Before the Trustee acts or refrains from acting, it may
require an Officer's Certificate and 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 such certificate or opinion.

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

                  (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers.

                  (e) The Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, notice, request, direction, consent, order, bond,
debenture, or other paper or document, but the Trustee, in its discretion, may
make such further inquiry or investigation into such facts or matters as it may
see fit and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company or any Subsidiary Guarantor, personally or by agent or attorney
at the sole cost of the Company and shall incur no liability or additional
liability of any kind by reason of such investigation.

                  (f) The Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Indenture at the request, order or
direction of any of the Holders, pursuant to the provisions of this Indenture,
unless such Holders shall have offered to the Trustee reasonable security or
indemnity satisfactory to it against the costs, expenses and liabilities which
may be incurred therein or thereby.

                  (g) The Trustee may consult with counsel of its selection and
the advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection of any action taken, suffered or omitted by the
Trustee hereunder in good faith and in reliance thereon.

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

                                       46

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

                  (j) In no event shall the Trustee be responsible or liable for
special, indirect or consequential loss or damage of any kind whatsoever
(including, but not limited to, loss of profit) irrespective of whether the
Trustee has been advised of the likelihood of such loss or damage and regardless
of the form of action.

                  (k) The permissive rights of the Trustee enumerated herein
shall not be construed as duties.

Section 6.03 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
any Subsidiary Guarantor, or their respective Affiliates, with the same rights
it would have if it were not Trustee. Any Paying Agent or Security Registrar may
do the same with like rights.

Section 6.04 Trustee's Disclaimer.

                  The Trustee makes no representation as to the validity or
adequacy of this Indenture or the Securities or any Subsidiary Guarantee and it
shall not be accountable for the Company's or any Subsidiary Guarantor's use of
the proceeds from the Securities, and it shall not be responsible for any
statement in the Securities or any Subsidiary Guarantee, other than the
Trustee's certificate of authentication, or the use or application of any funds
received by a Paying Agent other than the Trustee.

Section 6.05 Notice of Default.

                  If an Event of Default with respect to Securities of any
series occurs and is continuing and if it is known to the Trustee, the Trustee
shall mail to each Holder of Securities of such series notice of the uncured
Event of Default within 90 days after such Event of Default occurs. Except in
the case of an Event of Default in payment of principal (or premium, if any) of,
or interest on, any Security, the Trustee may withhold the notice if and so long
as a Responsible Officer in good faith determines that withholding the notice is
in the interest of the Holders of Securities of such series.

Section 6.06 Reports by Trustee to Holders.

                  Within 60 days after each February 15 beginning with the
February 15 following the date of this Indenture, the Trustee shall mail to each
Holder a brief report dated as of such February 15 that complies with Trust
Indenture Act Section 313(a) if such report is required by such Trust Indenture
Act Section 313(a). The Trustee also shall comply with Trust Indenture Act
Sections 313(c) and 313(d).

                                       47

                  The Company shall promptly notify the Trustee in writing if
the Securities of any series become listed on any stock exchange or automatic
quotation system.

                  A copy of each report at the time of its mailing to Holders
shall be mailed to the Company and filed with the Commission and each stock
exchange, if any, on which the Securities are listed.

Section 6.07 Compensation and Indemnity.

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

                  The Company and the Subsidiary Guarantors, jointly and
severally, shall indemnify each of the Trustee (in its capacity as Trustee) and
any predecessor Trustee and each of their respective officers, directors,
attorneys-in-fact and agents for, and hold it harmless against, any claim,
demand, expense (including but not limited to reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel), loss, damage,
charges (including taxes (other than taxes based upon the income of the
Trustee)) or liability incurred by them without gross negligence or willful
misconduct on its part, arising out of or in connection with the acceptance or
administration of this trust and their rights or duties hereunder including the
reasonable costs and expenses of defending themselves against any claim or
liability in connection with the exercise or performance of any of its powers or
duties hereunder. The Trustee shall notify the Company and the Subsidiary
Guarantors promptly of any claim asserted against the Trustee for which it may
seek indemnity. The Company shall defend the claim and the Trustee shall provide
reasonable cooperation at the Company's expense in the defense. The Trustee may
have separate counsel and the Company shall pay the reasonable fees and expenses
of such counsel. The Company and the Subsidiary Guarantors need not pay for any
settlement made without their written consent, which consent shall not be
unreasonably withheld. The Company and the Subsidiary Guarantors need not
reimburse any expense or indemnify against any loss or liability incurred by the
Trustee to the extent determined by a court of competent jurisdiction to have
been caused by its own gross negligence, or willful misconduct.

                  To secure the Company's and the Subsidiary Guarantors' payment
obligations in this Section 6.07, the Trustee shall have a lien prior to the
Securities on all assets held or collected by the Trustee, in its capacity as
Trustee, except assets held in trust to pay principal and premium, if any, of or
interest on any series of Securities.

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 5.01(7) or (8) occurs, the expenses and
the compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

                                       48

                  The Company's and the Subsidiary Guarantors' obligations under
this Section 6.07 and any lien arising hereunder shall survive the resignation
or removal of the Trustee, the discharge of the Company's and the Subsidiary
Guarantors' obligations pursuant to Article IV or Article XIV of this Indenture
and any rejection or termination of this Indenture under any Bankruptcy Law.

Section 6.08 Replacement of Trustee.

                  The Trustee may resign at any time with respect to the
Securities of one or more series by so notifying the Company and the Subsidiary
Guarantors in writing. The Holder or Holders of a majority in principal amount
of the outstanding Securities of a series may remove the Trustee with respect to
Securities of such series by so notifying the Company and the Trustee in writing
and may appoint a successor trustee with respect to Securities of such series
with the Company's consent. The Company may remove the Trustee if:

                  (1) the Trustee fails to comply with Section 6.10;

                  (2) the Trustee is adjudged bankrupt or insolvent;

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

                  (4) the Trustee becomes incapable of acting.

                  If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee, with respect to the Securities of one or more series, for
any reason, the Company shall promptly appoint a successor Trustee, with respect
to Securities of that or those series. Within one year after the successor
Trustee with respect to a series of Securities takes office, the Holder or
Holders of a majority in principal amount of the Securities of such series may
appoint a successor Trustee with respect to such series to replace the successor
Trustee appointed by the Company.

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that
and provided that all sums owing to the Trustee provided for in Section 6.07
have been paid, the retiring Trustee shall transfer all property held by it as
Trustee with respect to such series of Securities to the successor Trustee,
subject to the lien provided in Section 6.07, 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. A
successor Trustee with respect to one or more series of Securities shall mail
notice of its succession to each Holder of Securities of that or those series.

                  If a successor Trustee with respect to a series of Securities
does not take office within 60 days after the retiring Trustee resigns or is
removed, the retiring Trustee, the Company, the Subsidiary Guarantors or the
Holder or Holders of at least 10% in principal amount of the outstanding
Securities of that series may petition at the expense of the Company any court
of competent jurisdiction for the appointment of a successor Trustee with
respect to such series.

                                       49

                  If the Trustee fails to comply with Section 6.10, any Holder
of Securities of a series may petition any court of competent jurisdiction for
the removal of the Trustee with respect to such series and the appointment of a
successor Trustee with respect to such series.

                  Notwithstanding replacement of the Trustee pursuant to this
Section 6.08, the Company's obligations under Section 6.07 shall continue for
the benefit of the retiring Trustee.

Section 6.09 Successor Trustee by Merger, Etc.

                  If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the resulting, surviving or transferee corporation without any
further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee.

Section 6.10 Eligibility; Disqualification.

                  The Trustee shall at all times satisfy the requirements of
Trust Indenture Act Section 310(a)(1) and Trust Indenture Act Section 310(a)(5).
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 condition. The Trustee
shall comply with Trust Indenture Act Section 310(b).

Section 6.11 Preferential Collection of Claims against Company.

                  The Trustee shall comply with Trust Indenture Act Section
311(a), excluding any creditor relationship listed in Trust Indenture Act
Section 311(b). A Trustee who has resigned or been removed shall be subject to
Trust Indenture Act Section 311(a) to the extent indicated.

reasonably practicable, the names and addresses of Holders contained in the most
recent list furnished to the Trustee as provided in Section 7.01 and the names

                  A copy of each such report shall, at the time of such

Section 13 or 15(d) of the Securities Exchange Act of 1934 shall be filed with
the Trustee within 15 days after the same is so required to be filed with the
Commission. Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officer's Certificates).

         of interest thereon or any premium payable upon the redemption thereof,
         or reduce the amount of the principal of an Original Issue Discount
         Security that would be due and payable upon a declaration of
         acceleration of the Maturity thereof pursuant to Section 5.02, or
         change any Place of Payment where, or the coin or currency in which,
         any Security or any premium or interest thereon is payable or the right
         of selection thereof, or impair the right to institute suit for the
         enforcement of any such payment on or after the Stated Maturity thereof
         (or, in the case of redemption, on or after the Redemption Date), or
         adversely affect the right to convert any Security as provided in
         Article XV, or modify the provisions of this Indenture with respect to
         the ranking of the Securities in a manner adverse to the Holders;

                                       55

                  (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any such supplemental indenture, or the consent of whose
         Holders is required for any waiver (of compliance with certain
         provisions of this Indenture or certain defaults hereunder and their
         consequences) provided for in this Indenture;

                  (3) modify any of the provisions of this Section or Section
         5.13, except to increase any such percentage or to provide that certain
         other provisions of this Indenture cannot be modified or waived without
         the consent of the Holder of each Outstanding Security affected
         thereby, provided, however, that this clause shall not be deemed to
         require the consent of any Holder with respect to changes in the
         references to "the Trustee" and concomitant changes in this Section, or
         the deletion of this proviso, in accordance with the requirements of
         Sections 6.08 and 9.01(10);

                  (4) modify or waive the provisions of Article XI;

                  (5) change any obligation of ours to pay additional amounts;

                  (6) adversely affect the right of repayment or repurchase at
         the option of the Holder; or

                  (7) reduce or postpone any sinking fund or similar provision.

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

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

Section 9.03 Execution of Supplemental Indentures.

                  In executing, or accepting the additional trusts created by,
any supplemental indenture permitted by this Article or the modifications
thereby of the trusts created by this Indenture, the Trustee shall be entitled
to receive, and (subject to Section 6.01) shall be fully protected in relying
upon, in addition to the documents required by Section 102, an Opinion of
Counsel stating that the execution of such supplemental indenture is authorized
or permitted by this Indenture. The Trustee may, but shall not be obligated to,
enter into any such supplemental indenture which affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise.

Section 9.04 Effect of Supplemental Indentures.

                  Upon the execution of any supplemental indenture under this
Article, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes; and
every Holder of Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.

                                       56

Section 9.05 Conformity with Trust Indenture Act.

                  Every supplemental indenture executed pursuant to this Article
shall conform to the requirements of the Trust Indenture Act.

Section 9.06 Reference in Securities to Supplemental Indentures.

                  Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company and
the Subsidiary Guarantors shall so determine, new Securities of any series so
modified as to conform, in the opinion of the Trustee, the Company and the
Subsidiary Guarantors, to any such supplemental indenture may be prepared and
executed by the Company, and the Subsidiary Guarantees endorsed thereon may be
executed by the Subsidiary Guarantors, and such new Securities may be
authenticated and delivered by the Trustee in exchange for Outstanding
Securities of such series.

                                   ARTICLE X

                                   COVENANTS

Section 10.01 Payment of Securities.

                  The Company covenants and agrees for the benefit of each
series of Securities that it will pay the principal of and interest on the
Securities of that series on the dates and in the manner provided in the
Securities of that series and this Indenture. An installment of principal,
premium, if any, or interest on the Securities shall be considered paid on the
date it is due if the Trustee or Paying Agent (other than the Company or an
Affiliate of the Company) holds for the benefit of the Holders, on that date,
immediately available funds deposited and designated for and sufficient to pay
the installment.

                  The Company shall pay interest on overdue principal and on
overdue installments of interest at the rate specified in the Securities
compounded semi-annually, to the extent lawful.

Section 10.02 Maintenance of Office or Agency.

                  The Company shall maintain in the Place of Payment for any
series of Securities an office or agency where Securities of that series may be
presented or surrendered for payment, where Securities of that series may be
surrendered for registration of transfer or exchange, where Securities of any
series that is convertible may be surrendered for conversion, and where notices
and demands to or upon the Company or any Subsidiary Guarantor in respect of the
Securities of that series, any Subsidiary Guarantees endorsed thereon and this
Indenture may be served. The Company and the Subsidiary Guarantors will give
prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. If at any time the Company or any Subsidiary
Guarantor shall fail to maintain any such required office or agency or shall
fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and each of the Company and each Subsidiary Guarantor
hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands.

                                       57

                  The Company may also from time to time designate one or more
other offices or agencies where the Securities of one or more series may be
presented or surrendered for any or all such purposes and may from time to time
rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in each Place of Payment for Securities of any series for
such purposes. The Company shall give prompt written notice to the Trustee of
any such designation or rescission and of any change in the location of any such
other office or agency. The Company hereby initially designates the principal
corporate trust office of the Trustee as such office of the Company.

Section 10.03 Money for Securities Payments to Be Held in Trust.

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

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

                  The Company will cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will (1) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2)
during the continuance of any default by the Company (or any other obligor upon
the Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

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

                                       58

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of or any
premium or interest on any Security of any series and remaining unclaimed for
two years after such principal, premium or interest has become due and payable
shall be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in New York City, notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

Section 10.04 Corporate Existence.

                  Subject to Article VIII, the Company shall do or cause to be
done all things necessary to preserve and keep in full force and effect its
corporate existence and the corporate or other existence of each of its
Subsidiaries in accordance with the respective organizational documents of each
of them and the rights (charter and statutory) and corporate franchises of the
Company and each of its Subsidiaries; provided, however, that the Company shall
not be required to preserve, with respect to itself, any right or franchise, and
with respect to any of its Subsidiaries, any such existence, right or franchise,
if (a) the Board of Directors of the Company shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and (b) the loss thereof is not disadvantageous in any material
respect to the Holders.

Section 10.05 Payment of Taxes and Other Claims.

                  The Company shall, and shall cause each of its Subsidiaries
to, pay or discharge or cause to be paid or discharged, before the same shall
become delinquent, (i) all taxes, assessments and governmental charges
(including withholding taxes and any penalties, interest and additions to taxes)
levied or imposed upon the Company or any of its Subsidiaries or properties and
assets of the Company or any of its Subsidiaries and (ii) all lawful claims,
whether for labor, materials, supplies, service or anything else, which have
become due and payable and which by law have or may become a Lien upon the
property and assets of the Company or any of its Subsidiaries; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings and for which disputed amounts adequate reserves have been
established in accordance with generally accepted accounting principles.

                                       59

Section 10.06 Compliance Certificate; Notice of Default.

                  (a) The Company shall deliver to the Trustee within 120 days
after the end of its fiscal year an Officer's Certificate complying with Section
314(a)(4) of the Trust Indenture Act and stating that a review of its activities
and the activities of its Subsidiaries during the preceding fiscal year has been
made under the supervision of the signing officers with a view to determining
whether the Company has kept, observed, performed and fulfilled its obligations
under this Indenture (all without regard to periods of grace, which shall be
deemed fulfilled unless and until the expiration of such periods, or notice
requirements) and further stating, as to each such officer signing such
certificate, whether or not the signer knows of any failure by the Company or
any Subsidiary of the Company to comply with any conditions or covenants in this
Indenture and, if such signer does know of such a failure to comply, the
certificate shall describe such failure with particularity. The Officer's
Certificate shall also notify the Trustee should the relevant fiscal year end on
any date other than the current fiscal year end date.

                  (b) The Company shall, so long as any of the Securities of any
series are outstanding, deliver to the Trustee, immediately upon becoming aware
of any Event of Default with respect to such series under this Indenture, an
Officer's Certificate specifying such Event of Default and what action the
Company or the Subsidiary Guarantors is taking or proposes to take with respect
thereto. The Trustee shall not be deemed to have knowledge of an Event of
Default unless one of its Responsible Officers receives notice of the Event of
Default from the Company or any of the Holders.

Section 10.07 Limitation on Liens.

                  The Company shall not, and shall not permit any of its
Significant Subsidiaries to, issue, incur, assume or Guaranty any Indebtedness
for borrowed money secured by a Lien (other than Permitted Liens) upon any
shares of the Voting Stock of a Significant Subsidiary without effectively
providing that the Securities (and if the Company so elects, any other
indebtedness of the Company ranking on a parity with the Securities) shall be
secured equally and ratably with, or prior to, any such secured Indebtedness so
long as such Indebtedness remains outstanding.

Section 10.08 Limitation on Transactions with Affiliates.

                  The Company will not, and will not permit any of its
Subsidiaries to, sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or asset from, or enter into
any transaction, contract, agreement, understanding, loan, advance or guarantee
with, or for the benefit of, any Affiliate (each of the foregoing, an "Affiliate
Transaction"), unless (a) such Affiliate Transaction is made on terms that are
no less favorable to the Company or the relevant Subsidiary than those that
would have been obtained in a comparable transaction by the Company or such
Subsidiary with an unrelated person and (b) the Company delivers to the Trustee
with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of [$25 million] in any
fiscal year, a resolution of the Board of Directors set forth in an Officers'
Certificate certifying that such Affiliate Transaction or series of related
Affiliate Transactions complies with clause (a) above and such Affiliate
Transaction or series of related Affiliate Transactions has been approved by a
majority of the disinterested members of the Board of Directors; provided,
however, that (i) any employment agreement entered into by the Company or any of
its Subsidiaries in the ordinary course of business and consistent with the past
practice of the Company or such Subsidiary; (ii) transactions between or among
the Company and/or its Subsidiaries, and (iii) Affiliate Transactions entered
into prior to the date of issuance of the Securities under this Indenture, shall
be deemed not to be Affiliate Transactions.

                                   ARTICLE XI

                            REDEMPTION OF SECURITIES

Section 11.01 Applicability of Article.

                  Securities of any series which are redeemable before their
Stated Maturity shall be redeemable in accordance with their terms and (except
as otherwise specified as contemplated by Section 3.01 for Securities of any
series) in accordance with this Article.

Section 11.02 Election to Redeem; Notice to Trustee.

                  The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution. In case of any redemption at the election of
the Company of less than all the Securities of any series, the Company shall, at
least 60 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date, of the principal amount of Securities of such series to be
redeemed and, if applicable, of the tenor of the Securities to be redeemed. In
the case of any redemption of Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officer's Certificate evidencing compliance with such restriction.

Section 11.03 Selection by Trustee of Securities to Be Redeemed.

                  If less than all the Securities of any series are to be
redeemed (unless all of the Securities of such series and of a specified tenor
are to be redeemed), the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee from the
Outstanding Securities of such series not previously called for redemption, by
such method as the Trustee shall deem fair and appropriate and which may provide
for the selection for redemption of portions (equal to the minimum authorized
denomination for Securities of that series or any integral multiple thereof) of
the principal amount of Securities of such series of a denomination larger than
the minimum authorized denomination for Securities of that series. If less than
all of the Securities of such series and of a specified tenor are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee from the Outstanding
Securities of such series and specified tenor not previously called for
redemption in accordance with the preceding sentence.

                  If any Security selected for partial redemption is converted
in part before termination of the conversion right with respect to the portion
of the Security so selected, the converted portion of such Security shall be
deemed (so far as may be) to be the portion selected for redemption. Securities
which have been converted during a selection of Securities to be redeemed shall
be treated by the Trustee as Outstanding for the purpose of such selection.

                                       61

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

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

Section 11.04 Notice of Redemption.

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

                  All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price,

                  (3) if less than all the Outstanding Securities of any series
         are to be redeemed, the identification (and, in the case of partial
         redemption of any Securities, the principal amounts) of the particular
         Securities to be redeemed,

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

                  (5) in the case of any Securities that are convertible
         pursuant to Article XV, the conversion price or rate, the date on which
         the right to convert the principal of the Securities to be redeemed
         will terminate and the place or places where such Securities may be
         surrendered for conversion,

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

                  (7) that the redemption is for a sinking fund, if such is the
         case, and

                  (8) applicable CUSIP Numbers.

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

                                       62

Section 11.05 Deposit of Redemption Price.

                  Prior to 10 am, New York City time, on any Redemption Date,
the Company shall deposit with the Trustee or with a Paying Agent an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date other than any Securities called for
redemption on that date which have been converted prior to the date of such
deposit.

                  If any Security called for redemption is converted, any money
deposited with the Trustee or with any Paying Agent or so segregated and held in
trust for the redemption of such Security shall (subject to any right of the
Holder of such Security or any Predecessor Security to receive interest as
provided in the last paragraph of Section 3.07) be paid to the Company upon
Company Request or, if then held by the Company, shall be discharged from such
trust.

Section 11.06 Securities Payable on Redemption Date.

                  Notice of redemption having been given as aforesaid, the
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date
(unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender
of any such Security for redemption in accordance with said notice, such
Security shall be paid by the Company at the Redemption Price, together with
accrued interest to the Redemption Date; provided, however, that, unless
otherwise specified as contemplated by Section 3.01, installments of interest
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 3.07.

                  If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal and any premium shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

Section 11.07 Securities Redeemed in Part.

                  Any Security which is to be redeemed only in part shall be
surrendered at a Place of Payment thereof (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing), and the Company shall execute, and
the Subsidiary Guarantors shall execute their Subsidiary Guarantees to be
endorsed on, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities of the same
series and of like tenor, of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.

                                       63

                                  ARTICLE XII

                                 SINKING FUNDS

Section 12.01 Applicability of Article.

                  The provisions of this Article shall be applicable to any
sinking fund for the retirement of Securities of a series except as otherwise
specified as contemplated by Section 3.01 for Securities of such series.

                  The minimum amount of any sinking fund payment provided for by
the terms of Securities of any series is herein referred to as a "mandatory
sinking fund payment", and any payment in excess of such minimum amount provided
for by the terms of Securities of any series is herein referred to as an
"optional sinking fund payment". If provided for by the terms of Securities of
any series, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 12.02. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

Section 12.02 Satisfaction of Sinking Fund Payments with Securities.

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

Section 12.03 Redemption of Securities for Sinking Fund.

                  Not less than 60 days prior to each sinking fund payment date
for any series of Securities, the Company will deliver to the Trustee an
Officer's Certificate specifying the amount of the next ensuing sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting Securities
of that series pursuant to Section 12.02, and will also deliver to the Trustee
any Securities to be so delivered. Not less than 30 days before each such
sinking fund payment date the Trustee shall select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 11.03 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 11.04. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Sections 11.06 and 11.07.

                                  ARTICLE XIII

                              SUBSIDIARY GUARANTEE

Section 13.01 Subsidiary Guarantee.

                  Each of the Subsidiary Guarantors hereby jointly and severally
unconditionally Guarantees to each Holder of a Security of a series as to which
it is a Subsidiary Guarantor authenticated and delivered by the Trustee, and to
the Trustee on behalf of such Holder, the due and punctual payment of the
principal of (and premium, if any) and interest on such Security when and as the
same shall become due and payable, whether at the Stated Maturity, by
acceleration, call for redemption, purchase or otherwise, in accordance with the
terms of such Security and of this Indenture. In case of the failure of the
Company punctually to make any such payment, each of the Subsidiary Guarantors
hereby jointly and severally agrees to cause such payment to be made punctually
when and as the same shall become due and payable, whether at the Stated
Maturity or by acceleration, call for redemption, purchase or otherwise, and as
if such payment were made by the Company.

                  Each of the Subsidiary Guarantors hereby jointly and severally
agrees that its obligations hereunder shall be unconditional, irrespective of
the validity, regularity or enforceability of such Security or this Indenture,
the absence of any action to enforce the same, any exchange, release or
non-perfection of any Lien on any collateral for, or any release or amendment or
waiver of any term of any other Guarantee of, or any consent to departure from
any requirement of any other Guarantee of all or any of the Securities, the
election by the Trustee or any of the Holders in any proceeding under Chapter 11
of Title 11 of the United States Code (the "Bankruptcy Code") of the application
of Section 1111(b)(2) of the Bankruptcy Code, any borrowing or grant of a
security interest by the Company, as debtor-in-possession, under Section 364 of
the Bankruptcy Code, the disallowance, under Section 502 of the Bankruptcy Code,
of all or any portion of the claims of the Trustee or any of the Holders for
payment of any of the Securities, any waiver or consent by the Holder of such
Security or by the Trustee with respect to any provisions thereof or of this
Indenture, the obtaining of any judgment against the Company or any action to
enforce the same or any other circumstances which might otherwise constitute a
legal or equitable discharge or defense of a guarantor. Each of the Subsidiary
Guarantors hereby waives the benefits of diligence, presentment, demand for
payment, any requirement that the Trustee or any of the Holders protect, secure,
perfect or insure any security interest in or other Lien on any property subject
thereto or exhaust any right or take any action against the Company or any other
Person or any collateral, filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding first
against the Company, protest or notice with respect to such Security or the
Indebtedness evidenced thereby and all demands whatsoever, and covenants that
this Subsidiary Guarantee will not be discharged in respect of such Security
except by complete performance of the obligations contained in such Security and
in this Subsidiary Guarantee. Each of the Subsidiary Guarantors hereby agrees
that, in the event of a default in payment of principal (or premium, if any) or
interest on such Security, whether at their Stated Maturity, by acceleration,
call for redemption, purchase or otherwise, legal proceedings may be instituted
by the Trustee on behalf of, or by, the Holder of such Security, subject to the
terms and conditions set forth in this Indenture, directly against each of the


                                       65

Subsidiary Guarantors to enforce this Subsidiary Guarantee without first
proceeding against the Company. Each Subsidiary Guarantor agrees that if, after
the occurrence and during the continuance of an Event of Default with respect to
the Securities of the series as to which it is a Subsidiary Guarantor, the
Trustee or any of the Holders are prevented by applicable law from exercising
their respective rights to accelerate the maturity of the Securities of such
series, to collect interest on the Securities of such series, or to enforce or
exercise any other right or remedy with respect to the Securities of such
series, or the Trustee or the Holders are prevented from taking any action to
realize on any collateral, such Subsidiary Guarantor agrees to pay to the
Trustee for the account of the Holders, upon demand therefor, the amount that
would otherwise have been due and payable had such rights and remedies been
permitted to be exercised by the Trustee or any of the Holders.

                  Each Subsidiary Guarantor shall be subrogated to all rights of
the Holders of the Securities upon which its Subsidiary Guarantee is endorsed
against the Company in respect of any amounts paid by such Subsidiary Guarantor
on account of such Security pursuant to the provisions of its Subsidiary
Guarantee or this Indenture; provided, however, that no Subsidiary Guarantor
shall be entitled to enforce or to receive any payments arising out of, or based
upon, such right of subrogation until the principal of (and premium, if any) and
interest on all Securities issued hereunder as to which such Subsidiary
Guarantor is a Subsidiary Guarantor shall have been paid in full.

                  Each Subsidiary Guarantee shall remain in full force and
effect and continue to be effective should any petition be filed by or against
the Company for liquidation or reorganization, should the Company become
insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any significant part of the
Company's assets, and shall, to the fullest extent permitted by law, continue to
be effective or be reinstated, as the case may be, if at any time payment and
performance of the Securities is, pursuant to applicable law, rescinded or
reduced in amount, or must otherwise be restored or returned by any obligee on
the Securities, whether as a "voidable preference," "fraudulent transfer," or
otherwise, all as though such payment or performance had not been made. In the
event that any payment, or any part thereof, is rescinded, reduced, restored or
returned, the Securities shall, to the fullest extent permitted by law, be
reinstated and deemed reduced only by such amount paid and not so rescinded,
reduced, restored or returned.

                  The Subsidiary Guarantors shall have the right to seek
contribution from any non-paying Subsidiary Guarantor so long as the exercise of
such right does not impair the rights of the Holders under this Subsidiary
Guarantee.

Section 13.02 Execution and Delivery of Subsidiary Guarantees.

                  The Subsidiary Guarantees to be endorsed on the Securities of
any series shall include the terms of the Subsidiary Guarantee set forth in
Section 13.01 and any other terms that may be set forth in the form established
pursuant to Section 2.06. Each of the Subsidiary Guarantors hereby agrees to
execute its Subsidiary Guarantee, in a form established pursuant to Section
2.06, to be endorsed on each Security as to which it is a Subsidiary Guarantor
authenticated and delivered by the Trustee.

                                       66

                  The Subsidiary Guarantee shall be executed on behalf of each
respective Subsidiary Guarantor by any one of such Subsidiary Guarantor's
Chairman of the Board, Vice Chairman of the Board, President, Vice President or
other person duly authorized by the Board of Directors of such Subsidiary
Guarantor, attested by its Secretary or Assistant Secretary. The signature of
any or all of these persons on the Subsidiary Guarantee may be manual or
facsimile.

                  A Subsidiary Guarantee bearing the manual or facsimile
signature of individuals who were at any time the proper officers of a
Subsidiary Guarantor shall bind such Subsidiary Guarantor, notwithstanding that
such individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of the Security on which such Subsidiary Guarantee
is endorsed or did not hold such offices at the date of such Subsidiary
Guarantee.

                  The delivery of any Security by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of the
Subsidiary Guarantee endorsed thereon on behalf of the Subsidiary Guarantors.
Each of the Subsidiary Guarantors hereby jointly and severally agrees that its
Subsidiary Guarantee set forth in Section 13.01 shall remain in full force and
effect notwithstanding any failure to endorse a Subsidiary Guarantee on any
Security.

Section 13.03 Subsidiary Guarantors May Consolidate, Etc., on Certain Terms.

                  Except as set forth in Section 13.04 and in Article VIII and
the terms of the Securities, nothing contained in this Indenture or in any of
the Securities shall prevent any consolidation or merger of a Subsidiary
Guarantor with or into the Company or another Subsidiary Guarantor or shall
prevent any conveyance, transfer or lease of the property and assets of a
Subsidiary Guarantor substantially as an entirety to the Company or another
Subsidiary Guarantor.

Section 13.04 Release of Subsidiary Guarantors.

                  (a) Concurrently with any consolidation or merger of a
Subsidiary Guarantor or any conveyance, transfer or lease of the property of a
Subsidiary Guarantor as an entirety or substantially as an entirety, in each
case as permitted by Section 13.03 hereof, and upon delivery by the Company to
the Trustee of an Officer's Certificate and an Opinion of Counsel to the effect
that such consolidation, merger, conveyance, transfer or lease was made in
accordance with Section 13.03 hereof, the Trustee shall execute any documents
reasonably required in order to acknowledge the release of such Subsidiary
Guarantor from its obligations under its Subsidiary Guarantee endorsed on the
Securities and under this Article XIII. Any Subsidiary Guarantor not released
from its obligations under its Subsidiary Guarantee endorsed on the Securities
and under this Article XIII shall remain liable for the full amount of principal
of (and premium, if any) and interest on the Securities of a series as to which
it is a Subsidiary Guarantor and for the other obligations of a Subsidiary
Guarantor under its Subsidiary Guarantee endorsed on such Securities and under
this Article XIII.

                  (b) Concurrently with the defeasance of the Securities under
Section 14.02 hereof, the Subsidiary Guarantors shall be released from all of
their obligations under their Subsidiary Guarantees endorsed on the Securities
and under this Article XIII, without any action on the part of the Trustee or
any Holder of Securities.

                                       67

                  (c) Upon the sale or disposition (by merger or otherwise) of
any Subsidiary Guarantor by the Company or any Subsidiary of the Company
constituting an asset sale permitted under the terms of the Securities of any
series to a Person other than the Company or a Subsidiary Guarantor of the
Company and which is otherwise in compliance with the terms of this Indenture
and the terms of the Securities of such series, such Subsidiary Guarantor shall
automatically be released from all obligations under its Subsidiary Guarantees
endorsed on the Securities of such series and under this Article XIII, provided
that all other obligations of such Subsidiary Guarantor with respect to any
Indebtedness of the Company or any Subsidiary of the Company shall also
terminate upon such transaction.

Section 13.05 Additional Subsidiary Guarantors.

                  (a) The Company may cause any of its Subsidiaries to become a
Subsidiary Guarantor with respect to the Securities by executing and delivering
to the Trustee (a) a supplemental indenture, in form and substance satisfactory
to the Trustee, which subjects such Person to the provisions (including the
representations and warranties) of this Indenture as a Subsidiary Guarantor and
(b) an Opinion of Counsel to the effect that such supplemental indenture has
been duly authorized and executed by such Person and constitutes the legal,
valid, binding and enforceable obligation of such Person (subject to such
customary exceptions concerning creditors' rights and equitable principles as
may be acceptable to the Trustee in its discretion).

                  (b) The Company will cause any Subsidiary of the Company that
is required under the terms of the Securities of any series to become a
Subsidiary Guarantor to execute a supplemental indenture pursuant to which it
shall become a Subsidiary Guarantor.

Section 14.01 Company's Option to Effect Defeasance or Covenant Defeasance.

                  The Company may elect, at its option by Board Resolution at
any time, to have either Section 14.02 or Section 14.03 applied to the
Outstanding Securities of any series designated pursuant to Section 3.01 as
being defeasible pursuant to this Article XIV (hereinafter called a "Defeasible
Series"), upon compliance with the conditions set forth below in this Article
XIV.

                                       68

Section 14.02 Defeasance and Discharge.

                  Upon the Company's exercise of the option provided in Section
14.01 to have this Section 14.02 applied to the Outstanding Securities of any
Defeasible Series, the Company shall be deemed to have been discharged from its
obligations, and the provisions of Article XIII shall cease to be effective,
with respect to the Outstanding Securities of such series and the Subsidiary
Guarantors shall be deemed to have been discharged from their obligations with
respect to their Subsidiary Guarantees for such Outstanding Securities, as
provided in this Section on and after the date the conditions set forth in
Section 14.04 are satisfied (hereinafter called "Defeasance"), and the Trustee
shall deliver to the Company and the Subsidiary Guarantors appropriate
instruments of satisfaction, discharge and release. For this purpose, such
Defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by the Outstanding Securities of such series
and to have satisfied all its other obligations under the Securities of such
series and this Indenture, and the Subsidiary Guarantors shall be deemed to have
satisfied all of their obligations under their Subsidiary Guarantees and this
Indenture insofar as the Securities of such series are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until
otherwise terminated or discharged hereunder: (1) the rights of Holders of
Securities of such series to receive, solely from the trust fund described in
Section 14.04 and as more fully set forth in such Section, payments in respect
of the principal of and any premium and interest on such Securities of such
series when payments are due, (2) the Company's obligations with respect to the

applied to the Outstanding Securities of any Defeasible Series notwithstanding
the prior exercise of its option provided in Section 14.01 to have Section 14.03
applied to the Outstanding Securities of such series.

Section 14.03 Covenant Defeasance.

                  Upon the Company's exercise of the option provided in Section
14.01 to have this Section 14.03 applied to the Outstanding Securities of any
Defeasible Series, (1) the Company shall be released from its obligations under
Section 8.01 and Section 10.04, and the Subsidiary Guarantors shall be released
from their obligations under Section 8.02 and Article XIII and (2) the
occurrence of any event specified in Sections 5.01(3), 5.01(5) (with respect to
any of Sections 8.01, 8.02 and 10.04), 5.01(6) and 5.01(9) shall be deemed not
to be or result in an Event of Default, and (3) the provisions of Article XIII
shall cease to be effective, in each case with respect to the Outstanding
Securities of such series as provided in this Section on and after the date the
conditions set forth in Section 14.04 are satisfied (hereinafter called
"Covenant Defeasance"). For this purpose, such Covenant Defeasance means that
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such specified Section (to
the extent so specified in the case of Section 5.01(5)), whether directly or
indirectly by reason of any reference elsewhere herein to any such Section or by
reason of any reference in any such Section to any other provision herein or in
any other document, but the remainder of this Indenture and the Securities of
such series shall be unaffected thereby. In addition, Covenant Defeasance means
that each Subsidiary Guarantor, if any, shall be released from its obligations
under its Subsidiary Guarantee to the extent that the Company is released from
its obligations under this Indenture.

Section 14.04 Conditions to Defeasance or Covenant Defeasance.

                  The following shall be the conditions to application of either
Section 14.02 or Section 14.03 to the Outstanding Securities of any Defeasible
Series:

                                       69

                  (1) The Company shall irrevocably have deposited or caused to
         be deposited with the Trustee (or another trustee that satisfies the
         requirements contemplated by Section 6.09 and agrees to comply with the
         provisions of this Article XIV applicable to it) as trust funds in
         trust for the purpose of making the following payments, specifically
         pledged as security for, and dedicated solely to, the benefit of the
         Holders of Outstanding Securities of such series, (A) money in an
         amount, or (B) U.S. Government Obligations that through the scheduled
         payment of principal and interest in respect thereof in accordance with
         their terms will provide, not later than one day before the due date of
         any payment, money in an amount, or (C) a combination thereof, in each
         case sufficient, in the opinion of a nationally recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay and discharge, and which shall
         be applied by the Trustee (or any such other qualifying trustee) to pay
         and discharge, the principal of and any premium and interest on the
         Securities of such series on the respective Stated Maturities, in
         accordance with the terms of this Indenture and the Securities of such
         series. As used herein, "U.S. Government Obligation" means (x) any
         security that is (i) a direct obligation of the United States of
         America for the payment of which full faith and credit of the United
         States of America is pledged or (ii) an obligation of a Person
         controlled or supervised by and acting as an agency or instrumentality
         of the United States of America the payment of which is unconditionally
         guaranteed as a full faith and credit obligation by the United States
         of America, which, in either case (i) or (ii), is not callable or
         redeemable at the option of the issuer thereof, and (y) any depositary
         receipt issued by a bank (as defined in Section 3(a)(2) of the
         Securities Act of 1933, as amended) as custodian with respect to any
         U.S. Government Obligation specified in Clause (x) and held by such
         custodian for the account of the holder of such depositary receipt, or
         with respect to any specific payment of principal of or interest on any
         such U.S. Government Obligation, provided that (except as required by
         law) such custodian is not authorized to make any deduction from the
         amount payable to the holder of such depositary receipt from any amount
         received by the custodian in respect of the U.S. Government Obligation
         or the specific payment of principal or interest evidenced by such
         depositary receipt.

                  (2) In the case of an election under Section 14.02, the
         Company shall have delivered to the Trustee an Opinion of Counsel
         stating that (A) the Company has received from, or there has been
         published by, the Internal Revenue Service a ruling or (B) since the
         date first set forth hereinabove, there has been a change in the
         applicable Federal income tax law, in either case (A) or (B) to the
         effect that, and based thereon such opinion shall confirm that, the
         Holders of the Outstanding Securities of such series will not recognize
         gain or loss for Federal income tax purposes as a result of the
         deposit, Defeasance and discharge to be effected with respect to the
         Securities of such series and will be subject to Federal income tax on
         the same amount, in the same manner and at the same times as would be
         the case if such deposit, Defeasance and discharge were not to occur.

                  (3) In the case of an election under Section 14.03, the
         Company shall have delivered to the Trustee an Opinion of Counsel to
         the effect that the Holders of the Outstanding Securities of such
         series will not recognize gain or loss for Federal income tax purposes
         as a result of the deposit and Covenant Defeasance to be effected with
         respect to the Securities of such series and will be subject to Federal
         income tax on the same amount, in the same manner and at the same times
         as would be the case if such deposit and Covenant Defeasance were not
         to occur.

                                       70

                  (4) No Event of Default or event that (after notice or lapse
         of time or both) would become an Event of Default shall have occurred
         and be continuing at the time of such deposit or, with regard to any
         Event of Default or any such event specified in Sections 5.01(7) and
         (8), at any time on or prior to the 90th day after the date of such
         deposit (it being understood that this condition shall not be deemed
         satisfied until after such 90th day).

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

                  (6) The Company shall have delivered to the Trustee an
         Officer's Certificate and an Opinion of Counsel, each stating that all
         conditions precedent with respect to such Defeasance or Covenant
         Defeasance have been complied with.

Section 14.05 Deposited Money and U.S. Government Obligations to Be Held in
              Trust; Other Miscellaneous Provisions.

                  All money and U.S. Government Obligations (including the
proceeds thereof) deposited with the Trustee or other qualifying trustee (solely
for purposes of this Section and Section 14.06, the Trustee and any such other
trustee are referred to collectively as the "Trustee") pursuant to Section 14.04
in respect of the Securities of any Defeasible Series shall be held in trust and
applied by the Trustee, in accordance with the provisions of the Securities of
such series and this Indenture, to the payment, either directly or through any
such Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Holders of Securities of such series, of all sums
due and to become due thereon in respect of principal and any premium and
interest, but money so held in trust need not be segregated from other funds
except to the extent required by law.

                  The Company and the Subsidiary Guarantors (on a joint and
several basis) shall pay and indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against the U.S. Government Obligations deposited
pursuant to Section 14.04 or the principal and interest received in respect
thereof other than any such tax, fee or other charge that by law is for the
account of the Holders of Outstanding Securities.

                  Anything in this Article XIV to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 14.04 with respect to Securities of any Defeasible Series that, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof that would then be required to be deposited to
effect an equivalent Defeasance or Covenant Defeasance with respect to the
Securities of such series.

                                       71

Section 14.06 Reinstatement.

                  If the Trustee or the Paying Agent is unable to apply any
money in accordance with this Article XIV with respect to the Securities of any
series by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, then the
Company's obligations under this Indenture and the Securities of such series and
such Subsidiary Guarantor's obligation under its Subsidiary Guarantee and this
Indenture shall be revived and reinstated as though no deposit had occurred
pursuant to this Article XIV with respect to Securities of such series until
such time as the Trustee or Paying Agent is permitted to apply all money held in
trust pursuant to Section 14.05 with respect to Securities of such series in
accordance with this Article XIV; provided, however, that if the Company or a
Subsidiary Guarantor makes any payment of principal of or any premium or
interest on any Security of such series following the reinstatement of its
obligations, the Company or the Subsidiary Guarantor, as the case may be, shall
be subrogated to the rights of the Holders of Securities of such series to
receive such payment from the money so held in trust.

                                   ARTICLE XV

                            CONVERSION OF SECURITIES

Section 15.01 Applicability; Conversion Privilege and Conversion Price.

                  Securities of any series which are convertible into Common
Stock of the Company shall be convertible in accordance with their terms and
(except as otherwise specified as contemplated by Section 3.01 for Securities of
any series) in accordance with this Article.

                  Subject to and upon compliance with the provisions of this
Article, at the option of the Holder thereof, any Security or any portion of the
outstanding principal amount thereof which is $1,000 or an integral multiple of
$1,000 may be converted at the principal amount thereof, or of such portion
thereof, into fully paid and nonassessable shares (calculated as to each
conversion to the nearest 1/100 of a share) of Common Stock of the Company at
the conversion price, determined as hereinafter provided, in effect at the time
of conversion. Such conversion right shall expire at the close of business on
the date specified for Securities of such series. In case a Security or portion
thereof is called for redemption at the election of the Company, such conversion
right in respect of the Security or portion so called shall expire at the close
of business on the 10th calendar day before the Redemption Date, unless the
Company defaults in making the payment due upon redemption.

                  The price at which shares of Common Stock shall be delivered
upon conversion (herein called the "conversion price") shall be the price
specified in relation to Securities of such series pursuant to Section 3.01, as
it shall be adjusted in certain instances as provided in this Article.

                                       72

Section 15.02 Exercise of Conversion Price.

                  In order to exercise the conversion privilege, the Holder of
any Security to be converted shall surrender such Security, duly endorsed or
assigned to the Company or in blank, at any office or agency of the Company
maintained for that purpose pursuant to Section 10.02, accompanied by written
notice to the Company (which shall be substantially in the form set forth in
Section 2.03) at such office or agency that the Holder elects to convert such
Security or, if less than the entire principal amount thereof is to be
converted, the portion thereof to be converted. Securities surrendered for
conversion during the period from the close of business on any Regular Record
Date next preceding any Interest Payment Date to the opening of business on such
Interest Payment Date shall (except in the case of Securities or portions
thereof which have been called for redemption on a Redemption Date within such
period) be accompanied by payment in funds acceptable to the Company of an
amount equal to the interest payable on such Interest Payment Date on the
principal amount of Securities being surrendered for conversion. Subject to the
provisions of Section 3.07 relating to the payment of Defaulted Interest by the
Company, the interest payment with respect to a Security called for redemption
on a Redemption Date during the period from the close of business on any Regular
Record Date next preceding any Interest Payment Date to the opening of business
on such Interest Payment Date shall be payable on such Interest Payment Date to
the Holder of such Security at the close of business on such Regular Record Date
notwithstanding the conversion of such Security after such Regular Record Date
and prior to such Interest Payment Date, and the Holder converting such Security
need not include a payment of such interest payment amount upon surrender of
such Security for conversion. Except as provided in the preceding sentence and
subject to the final paragraph of Section 3.07, no payment or adjustment shall
be made upon any conversion on account of any interest accrued on the Securities
surrendered for conversion or on account of any dividends on the Common Stock
issued upon conversion.

                  Securities shall be deemed to have been converted immediately
prior to the close of business on the day of surrender of such Securities for
conversion in accordance with the foregoing provisions, and at such time the
rights of the Holders of such Securities as Holders shall cease, and the Person
or Persons entitled to receive the Common Stock issuable upon conversion shall
be treated for all purposes as the record holder or holders of such Common Stock
at such time. As promptly as practicable on or after the conversion date, the
Company shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 15.03.

                  In the case of any Security which is converted in part only,
upon such conversion the Company shall execute and the Trustee shall
authenticate and deliver to the Holder thereof, at the expense of the Company, a
new Security or Securities of authorized denominations in aggregate principal
amount equal to the unconverted portion of the principal amount of such
Security.

Section 15.03 Fractions of Shares.

                  No fractional shares of Common Stock shall be issued upon
conversion of Securities. If more than one Security shall be surrendered for
conversion at one time by the same Holder, the number of full shares which shall
be issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Securities (or specified portions thereof) so
surrendered. Instead of any fractional share of Common Stock which would
otherwise be issuable upon conversion of any Security or Securities (or
specified portions thereof), the Company shall pay a cash adjustment in respect
of such fraction in an amount equal to the same fraction of the daily closing
price per share of Common Stock (consistent with Section 15.04(6) below) at the
close of business on the day of conversion.

                                       73

Section 15.04 Adjustment of Conversion Price.

                  (1) In case the Company shall pay or make a dividend or other
         distribution on any class of capital stock of the Company in Common
         Stock, the conversion price in effect at the opening of business on the
         day following the date fixed for determination of stockholders entitled
         to receive such dividend or other distribution shall be reduced by
         multiplying such conversion price by a fraction of which the numerator
         shall be the number of shares of Common Stock outstanding at the close
         of business on the date fixed for such determination and the
         denominator shall be the sum of such number of shares and the total
         number of shares constituting such dividend or other distribution, such
         reduction to become effective immediately after the opening of business
         on the day following the date fixed for such determination. For the
         purposes of this paragraph (1), the number of shares of Common Stock at
         any time outstanding shall not include shares held in the treasury of
         the Company but shall include shares issuable in respect of scrip
         certificates issued in lieu of fractions of shares of Common Stock. The
         Company will not pay any dividend or make any distribution on shares of
         Common Stock held in the treasury of the Company.

                  (2) In case the Company shall issue rights or warrants to all
         holders of its Common Stock entitling them to subscribe for or purchase
         shares of Common Stock at a price per share less than the current
         market price per share (determined as provided in paragraph (6) of this
         Section) of the Common Stock on the date fixed for the determination of
         stockholders entitled to receive such rights or warrants (other than
         pursuant to a dividend reinvestment plan), the conversion price in
         effect at the opening of business on the day following the date fixed
         for such determination shall be reduced by multiplying such conversion
         price by a fraction of which the numerator shall be the number of
         shares of Common Stock outstanding at the close of business on the date
         fixed for such determination plus the number of shares of Common Stock
         which the aggregate of the offering price of the total number of shares
         of Common Stock so offered for subscription or purchase would purchase
         at such current market price and the denominator shall be the number of
         shares of Common Stock outstanding at the close of business on the date
         fixed for such determination plus the number of shares of Common Stock
         so offered for subscription or purchase, such reduction to become
         effective immediately after the opening of business on the day
         following the date fixed for such determination. For the purposes of
         this paragraph (2), the number of shares of Common Stock at any time
         outstanding shall not include shares held in the treasury of the
         Company but shall include shares issuable in respect of scrip
         certificates issued in lieu of fractions of shares of Common Stock. The
         Company will not issue any rights or warrants in respect of shares of
         Common Stock held in the treasury of the Company.

                                       74

                  (3) In case outstanding shares of Common Stock shall be
         subdivided into a greater number of shares of Common Stock, the
         conversion price in effect at the opening of business on the day
         following the day upon which such subdivision becomes effective shall
         be proportionately reduced, and, conversely, in case outstanding shares
         of Common Stock shall each be combined into a smaller number of shares
         of Common Stock, the conversion price in effect at the opening of
         business on the day following the day upon which such combination
         becomes effective shall be proportionately increased, such reduction or
         increase, as the case may be, to become effective immediately after the
         opening of business on the day following the day upon which such
         subdivision or combination becomes effective.

                  (4) In case the Company shall, by dividend or otherwise,
         distribute to all holders of its Common Stock evidences of its
         indebtedness or assets (including securities, but excluding any rights
         or warrants referred to in paragraph (2) of this Section, any dividend
         or distribution paid in cash out of the earned surplus of the Company
         and any dividend or distribution referred to in paragraph (1) of this
         Section), the conversion price shall be adjusted so that the same shall
         equal the price determined by multiplying the conversion price in
         effect immediately prior to the close of business on the date fixed for
         the determination of stockholders entitled to receive such distribution
         by a fraction of which the numerator shall be the current market price
         per share (determined as provided in paragraph (6) of this Section) of
         the Common Stock on the date fixed for such determination less the then
         fair market value (as determined by the Board of Directors, whose
         determination shall be conclusive and described in a Board Resolution
         filed with the Trustee) of the portion of the assets or evidences of
         indebtedness so distributed applicable to one share of Common Stock and
         the denominator shall be such current market price per share of the
         Common Stock, such adjustment to become effective immediately prior to
         the opening of business on the day following the date fixed for the
         determination of stockholders entitled to receive such distribution.

                  (5) The reclassification of Common Stock into securities other
         than Common Stock (other than any reclassification upon a consolidation
         or merger to which Section 15.11 applies) shall be deemed to involve
         (a) a distribution of such securities other than Common Stock to all
         holders of Common Stock (and the effective date of such
         reclassification shall be deemed to be "the date fixed for the
         determination of stockholders entitled to receive such distribution"
         and "the date fixed for such determination" within the meaning of
         paragraph (4) of this Section), and (b) a subdivision or combination,
         as the case may be, of the number of shares of Common Stock outstanding
         immediately prior to such reclassification into the number of shares of
         Common Stock outstanding immediately thereafter (and the effective date
         of such reclassification shall be deemed to be "the day upon which such
         subdivision becomes effective" or "the day upon which such combination
         becomes effective", as the case may be, and "the day upon which such
         subdivision or combination becomes effective" within the meaning of
         paragraph (3) of this Section).

                                       75

                  (6) For the purpose of any computation under paragraphs (2)
         and (4) of this Section, the current market price per share of Common
         Stock on any day shall be deemed to be the average of the daily closing
         prices for the five consecutive trading days (i.e., Business Days on
         which the Common Stock is traded) selected by the Board of Directors
         commencing not more than 20 trading days before, and ending not later
         than, the earlier of the day in question and the day before the "ex"
         date with respect to the issuance or distribution requiring such
         computation. For this purpose, the term "`ex' date", when used with
         respect to any issuance or distribution, shall mean the first date on
         which the Common Stock trades regular way on the applicable exchange or
         in the applicable market without the right to receive such issuance or
         distribution. The closing price for each day shall be the reported last
         sale price regular way or, in case no such reported sale takes place on
         such day, the average of the reported closing bid and asked prices
         regular way, in either case on the New York Stock Exchange or, if the
         Common Stock is not listed or admitted to trading on such Exchange, on
         the principal national securities exchange on which the Common Stock is
         listed or admitted to trading or, if not listed or admitted to trading
         on any national securities exchange, on the Nasdaq Stock Market or, if
         the Common Stock is not listed or admitted to trading on any national
         securities exchange or quoted on the Nasdaq Stock Market, the average
         of the closing bid and asked prices in the over-the-counter market as
         furnished by any New York Stock Exchange member firm selected from time
         to time by the Board of Directors for that purpose.

                  (7) The Company may make such reductions in the conversion
         price, in addition to those required by paragraphs (1), (2), (3) and
         (4) of this Section, as it considers to be advisable in order to avoid
         or diminish any income tax to any holders of shares of Common Stock
         resulting from any dividend or distribution of stock or issuance of
         rights or warrants to purchase or subscribe for stock or from any event
         treated as such for income tax purposes or for any other reasons. The
         Company shall have the power to resolve any ambiguity or correct any
         error pursuant to this paragraph (7) and its actions in so doing shall
         be final and conclusive.

                  (8) No adjustment in the conversion price shall be required
         unless such adjustment would require an increase or decrease of at
         least one percent in such conversion price; provided, however, that any
         adjustment which by reason of this paragraph (8) is not required to be
         made shall be carried forward and taken into account in any subsequent
         adjustment. All calculations under this Article shall be made to the
         nearest cent or to the nearest 1/100 of a share, as the case may be.

                                       76

Section 15.05 Notice of Adjustments of Conversion Price.

         Whenever the conversion price is adjusted as herein provided:

         (a)      the Company shall compute the adjusted conversion price in
                  accordance with Section 15.04 and shall prepare a certificate
                  signed by the Treasurer of the Company setting forth the
                  adjusted conversion price and showing in reasonable detail the
                  facts upon which such adjustment is based, and such
                  certificate shall forthwith be filed at each office or agency
                  maintained for the purpose of conversion of Securities
                  pursuant to Section 10.02; and

         (b)      a notice stating that the conversion price has been adjusted
                  and setting forth the adjusted conversion price shall
                  forthwith be required, and as soon as practicable after it is
                  required, such notice shall be mailed by the Company to all
                  Holders at their last addresses as they shall appear in the
                  Security Register.

Section 15.06 Notice of Certain Corporate Action.

         In case:

         (a)      the Company shall declare a dividend (or any other
                  distribution) on its Common Stock payable otherwise than in
                  cash out of its earned surplus; or

         (b)      the Company shall authorize the granting to the holders of its
                  Common Stock of rights or warrants to subscribe for or
                  purchase any shares of capital stock of any class or of any
                  other rights; or

         (c)      of any reclassification of the Common Stock of the Company
                  (other than a subdivision or combination of its outstanding
                  shares of Common Stock), or of any consolidation, merger or
                  share exchange to which the Company is a party and for which
                  approval of any stockholders of the Company is required, or of
                  the sale or transfer of all or substantially all of the assets
                  of the Company; or

         (d)      of the voluntary or involuntary dissolution, liquidation or
                  winding up of the Company;

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Securities pursuant to Section 10.02, and shall
cause to be mailed to all Holders at their last addresses as they shall appear
in the Security Register, at least 20 days (or 10 days in any case specified in
clause (a) or (b) above) prior to the applicable record or effective date
hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend, distribution, rights or warrants, or, if
a record is not to be taken, the date as of which the holders of Common Stock of
record to be entitled to such dividend, distribution, rights or warrants are to
be determined, or (y) the date on which such reclassification, consolidation,
merger, share exchange, sale, transfer, dissolution, liquidation or winding up
is expected to become effective, and the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, share exchange, sale, transfer,
dissolution, liquidation or winding up. Neither the failure to give such notice
nor any defect therein shall affect the legality or validity of the proceedings
described in clauses (a) through (d) of this Section 15.06. If at the time the
Trustee shall not be the conversion agent, a copy of such notice shall also
forthwith be filed by the Company with the Trustee.

                                       77

                  Not less than seven days prior to any date fixed for the
determination of stockholders entitled to receive such distribution, the Company
shall cause to be filed at each office or agency maintained for the purpose of
conversion of Securities pursuant to Section 10.02, and shall cause to be mailed
to all Holders at their last addresses as they shall appear in the Security
Register, a notice stating the date on which such determination is to be made,
and briefly describing the import thereof. If at the time the Trustee shall not
be the conversion agent, a copy of such notice shall also forthwith be filed by
the Company with the Trustee.

Section 15.07 Company to Reserve Common Stock.

                  The Company shall at all times reserve and keep available out
of its authorized but unissued Common Stock, for the purpose of effecting the
conversion of Securities, the full number of shares of Common Stock then
issuable upon the conversion of all Outstanding Securities.

Section 15.08 Taxes on Conversions.

                  The Company will pay any and all taxes that may be payable in
respect of the issue or delivery of shares of Common Stock on conversion of
Securities pursuant hereto. The Company shall not, however, be required to pay
any tax which may be payable in respect of any transfer involved in the issue
and delivery of shares of Common Stock in a name other than that of the Holder
of the Security or Securities to be converted, and no such issue or delivery
shall be made unless and until the Person requesting such issue has paid to the
Company the amount of any such tax, or has established to the satisfaction of
the Company that such tax has been paid.

Section 15.09 Covenant as to Common Stock.

                  The Company covenants that all shares of Common Stock which
may be issued upon conversion of Securities will upon issue be fully paid and
nonassessable and, except as provided in Section 15.08, the Company will pay all
taxes, liens and charges with respect to the issue thereof.

Section 15.10 Cancellation of Converted Securities.

                  All Securities delivered for conversion shall be delivered to
the Trustee to be cancelled by or at the direction of the Trustee, which shall
dispose of the same as provided in Section 3.09.

                                       78

Section 15.11 Provisions in Case of Consolidation, Merger or Sale of Assets.

                  In case of any consolidation of the Company with, or merger of
the Company into, any other Person, any merger of another Person into the
Company (other than a merger which does not result in any reclassification,
conversion, exchange or cancellation of outstanding shares of Common Stock of
the Company) or any sale or transfer of all or substantially all of the assets
of the Company, the Person formed by such consolidation or resulting from such
merger or which acquires such assets, as the case may be, shall execute and
deliver to the Trustee a supplemental indenture providing that the Holder of
each convertible Security then outstanding shall have the right thereafter,
during the period such Security shall be convertible as specified in Section
15.01, to convert such Security only into the kind and amount of securities,
cash and other property receivable upon such consolidation, merger, sale or
transfer by a holder of the number of shares of Common Stock of the Company into
which such Security might have been converted immediately prior to such
consolidation, merger, sale or transfer, assuming such holder of Common Stock of
the Company failed to exercise his rights of election, if any, as to the kind or
amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer (provided that if the kind or amount of
securities, cash and other property receivable upon such consolidation, merger,
sale or transfer is not the same for each share of Common Stock of the Company
in respect of which such rights of election shall not have been exercised
("non-electing share"), then for the purpose of this Section the kind and amount
of securities, cash and other property receivable upon such consolidation,
merger, sale or transfer by each non-electing share shall be deemed to be the
kind and amount so receivable per share by a plurality of the non-electing
shares). Such supplemental indenture shall provide for adjustments which, for
events subsequent to the effective date of such supplemental indenture, shall be
as nearly equivalent as may be practicable to the adjustments provided for in
this Article. The above provisions of this Section shall similarly apply to
successive consolidations, mergers, sales or transfers.

Section 15.12 Responsibility of Trustee.

                  Neither the Trustee nor any conversion agent shall at any time
be under any duty or responsibility to any Holder of Securities to determine
whether any fact exists which may require any adjustment of the conversion
price, or with respect to the nature or extent of any such adjustment when made,
or with respect to the method employed, or herein or in any supplemental
indenture provided to be employed, in making the same. Neither the Trustee nor
any conversion agent shall be accountable with respect to the registration,
validity or value (or the kind or amount) of any shares of Common Stock, or of
any securities or property, which may at any time be issued or delivered upon
the conversion of any Security; and neither the Trustee nor any conversion agent
makes any representation with respect thereto. Neither the Trustee nor any
conversion agent shall be responsible for any failure of the Company to issue or
transfer or deliver any Common Stock or stock certificates or other securities
or property or to make any cash payment upon the surrender of any Security for
the purpose of conversion or to comply with any of the covenants of the Company
contained in this Article XV.

                                       79

                  The Trustee makes no representations as to the validity or
sufficiency of this Indenture; the recitals and statements herein are deemed to
be those of the Company and not of the Trustee.

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