                    AMENDMENT TO DELPHI FINANCIAL GROUP, INC.
         AMENDED AND RESTATED LONG-TERM PERFORMANCE-BASED INCENTIVE PLAN

Effective January 1, 2005, a new Section 10 is added to the above-referenced
Plan, to read as follows:

    10.  COMPLIANCE WITH SECTION 409A

          It is intended that Deferred Shares granted prior to January 1,
    2005, to the extent that as of December 31, 2004, such Deferred Shares
    were vested, will satisfy the grandfather provisions applicable under
    Section 409A of the Code so that such Deferred Shares (together with
    any dividend equivalents thereon) will not be subject to Section 409A
    of the Code. No amendment to this Plan made after October 3, 2004 will
    apply to Deferred Shares granted prior to January 1, 2005 (or to
    dividend equivalents thereon) unless the amendment specifically
    provides that it applies to such Deferred Shares. It is intended that
    Deferred Shares granted on or after January 1, 2005 will comply with
    Section 409A of the Code and any regulations and guidelines issued
    thereunder, and the Plan will be interpreted in a manner consistent
    with such intent. Accordingly, the terms of any Deferred Shares granted
    after January 1, 2005 under the Plan, as set forth in an applicable
    Award agreement, may differ from the specific terms contemplated by the
    Plan in any manner that would not adversely affect the Company, to the
    extent necessary for the Deferred Shares so granted to comply with
    Section 409A of the Code.<PAGE>

                                                                  EXECUTION COPY

thereby.

      Any of the Debentures may have such letters, numbers or other marks of
identification and such notations, legends, endorsements or changes as the
officers executing the same may approve (execution thereof to be conclusive
evidence of such approval) and as are not inconsistent with the provisions of

any other market developed for trading of securities pursuant to Rule 144A or as
may be required to comply with any applicable law or with any rule or regulation
made pursuant thereto or with any rule or regulation of any securities exchange
or automated quotation system on which the Debentures may be listed, or to

which any particular Debentures are subject.

      So long as the Debentures are eligible for book-entry settlement with the
Depositary, or unless otherwise required by law, or otherwise contemplated by
Section 2.05(a), all of the Debentures will be represented by one or more
Debentures in global form registered in the name of the Depositary or the

aggregate amount of Outstanding Debentures from time to time endorsed thereon
and that the aggregate amount of Outstanding Debentures represented thereby may

registered on the Debenture Register at the close of business on any record date
with respect to any interest payment date shall be entitled to receive the
Interest and Additional Amounts, if any, payable on such interest payment date,

pursuant to such redemption or repurchase (unless the redemption date or the
Designated

                                       18

Event Repurchase Date, as the case may be, falls after a record date and on or
prior to the corresponding interest payment date, in which case the full
semi-annual payment of Interest and Additional Amounts, if any, becoming due on
such interest payment date shall be payable to the holders of such Debentures
registered as such on the corresponding record date). Interest and Additional
Amounts, if any, shall be payable at an office maintained by the Company for
such purposes in the Borough of Manhattan, City of New York, which shall
initially be an office or agency of the Trustee. The Company shall pay Interest
and Additional Amounts, if any, (i) on any Debentures in certificated form by
check mailed to the address of the Person entitled thereto as it appears in the
Debenture Register or (ii) on any Global Debenture by wire transfer of
immediately available funds to the account of the Depositary or its nominee. The
term "RECORD DATE" with respect to any interest payment date shall mean the

the terms set forth herein (herein called "DEFAULTED INTEREST AND ADDITIONAL
AMOUNTS") shall forthwith cease to be payable to the Debentureholder on the
relevant record date by virtue of his having been such Debentureholder, and such
Defaulted Interest and Additional Amounts shall 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 and
Additional Amounts to the Persons in whose names the Debentures (or their
respective Predecessor Debentures) are registered at the close of business on a
special record date for the payment of such Defaulted Interest and Additional
Amounts, which shall be fixed in the following manner. The Company shall notify
the Trustee in writing of the amount of Defaulted Interest and Additional
Amounts proposed to be paid on each Debenture and the date of the proposed
payment (which shall be not less than twenty-five (25) days after the receipt by
the Trustee of such notice, unless the Trustee shall consent to an earlier
date), and at the same time the Company shall deposit with the Trustee an amount
of money equal to the aggregate amount to be paid in respect of such Defaulted
Interest and Additional Amounts or shall make arrangements satisfactory to the
Trustee for such deposit on or 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 and Additional Amounts as in this clause provided.
Thereupon the Trustee shall fix a special record date (whether or not such date
is a Business Day) for the payment of such Defaulted Interest and Additional
Amounts that shall be not more than fifteen (15) days and not less than ten (10)
days prior to the date of the proposed payment, and not less than ten (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 Additional Amounts and the special record
date therefor to

                                       19
<PAGE>

be mailed, first-class postage prepaid, to each holder at his address as it
appears in the Debenture Register, not less than ten (10) days prior to such
special record date. Notice of the proposed payment of such Defaulted Interest
and Additional Amounts and the special record date therefor having been so
mailed, such Defaulted Interest and Additional Amounts shall be paid to the
Persons in whose names the Debentures (or their respective Predecessor
Debentures) are registered at the close of business on such special record date
and shall no longer be payable pursuant to the following clause (2) of this
Section 2.03.

      (2) The Company may make payment of any Defaulted Interest and Additional
Amounts in any other lawful manner not inconsistent with the requirements of any
securities exchange or automated quotation system on which the Debentures may be
listed or designated for issuance, and upon such notice as may be required by
such exchange or automated quotation system, 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.

      Section 2.04. Execution of Debentures. The Debentures shall be signed in
the name and on behalf of the Company by the manual or facsimile signature of
its Chairman of the Board, Chief Executive Officer, President or any Vice
President (whether or not designated by a number or numbers or word or words
added before or after the title "VICE PRESIDENT"). Only such Debentures as shall
bear thereon a certificate of authentication substantially in the form set forth
on the form of Debenture attached as Exhibit A hereto, manually executed by the
Trustee (or an authenticating agent appointed by the Trustee as provided by
Section 18.10), shall be entitled to the benefits of this Indenture or be valid
or obligatory for any purpose. Such certificate by the Trustee (or such an
authenticating agent) upon any Debenture executed by the Company shall be
conclusive evidence that the Debenture so authenticated has been duly
authenticated and delivered hereunder and that the holder is entitled to the
benefits of this Indenture.

      In case any officer of the Company or of a Subsidiary Guarantor, as the
case may be, who shall have signed any of the Debentures or any of the
Subsidiary Guarantees, as the case may be, shall cease to be such officer before
the Debentures or Subsidiary Guarantees, as the case may be, so signed shall
have been authenticated and delivered by the Trustee, or disposed of by the
Company, such Debentures or Subsidiary Guarantees, as the case may be,
nevertheless may be authenticated and delivered or disposed of as though the
person who signed such Debentures or Subsidiary Guarantees, as the case may be,
had not ceased to be such officer of the Company or of a Subsidiary Guarantor,
as the case may be, and any Debenture or Subsidiary Guarantees, as the case may
be, may be signed on behalf of the Company or of a Subsidiary Guarantor, as the
case may be, by such persons as, at the actual date of the execution of such
Debenture or Subsidiary Guarantees, as the case may be, shall be the proper
officers of the Company or of a Subsidiary Guarantor, as the case may be,
although at the date of the execution of this Indenture any such person was not
such an officer.

      Debentures may be exchanged for other Debentures of any authorized
denominations and of a like aggregate principal amount, upon surrender of the

to receive bearing registration numbers not contemporaneously Outstanding.

      All Debentures issued upon any registration of transfer or exchange of
Debentures shall be the valid obligations of the Company, evidencing the same

surrendered upon such registration of transfer or exchange.

Company or the Debenture Registrar) be duly endorsed, or be accompanied by a
written instrument or instruments of transfer in form satisfactory to the
Company, and the Debentures shall be duly executed by the Debentureholder
thereof or his attorney duly authorized in writing.

transfer or exchange of Debentures, but the Company and the Registrar may
require payment by the holder of a sum sufficient to cover any tax, assessment
or other governmental charge that may be imposed in connection with any
registration of transfer or exchange of Debentures.

            whole and not in part, and any Global Debenture exchanged pursuant
            to clauses (ii) or (iii) above may be exchanged in whole or from
            time to time in part as directed by the Depositary. Any Debenture
            issued in exchange for a Global Debenture or any portion thereof
            shall be a Global Debenture; provided that any such Debenture so
            issued that is registered in the name of a Person other than the
            Depositary or a nominee thereof shall not be a Global Debenture.

                  (iii) Securities issued in exchange for a Global Debenture or
            any portion thereof pursuant to clause (ii) above shall be issued in
            definitive, fully registered form, without interest coupons, shall
            have an

                                       22
<PAGE>

            aggregate principal amount equal to that of such Global Debenture or
            portion thereof to be so exchanged, shall be registered in such
            names and be in such authorized denominations as the Depositary
            shall designate and shall bear any legends required hereunder. Any
            Global Debenture to be exchanged in whole shall be surrendered by
            the Depositary to the Trustee, as Debenture Registrar. With regard
            to any Global Debenture to be exchanged in part, either such Global
            Debenture shall be so surrendered for exchange or, if the Trustee is
            acting as Custodian for the Depositary or its nominee with respect
            to such Global Debenture, the principal amount thereof shall be
            reduced, by an amount equal to the portion thereof to be so
            exchanged, by means of an appropriate adjustment made on the records
            of the Trustee. Upon any such surrender or adjustment, the Trustee
            shall authenticate and make available for delivery the Debenture
            issuable on such exchange to or upon the written order of the
            Depositary or an authorized representative thereof.

                  (iv) In the event of the occurrence of any of the events
            specified in clause (ii) above, the Company will promptly make
            available to the Trustee a reasonable supply of certificated
            Debentures in definitive, fully registered form, without interest
            coupons.

                  (v) Neither any members of, or participants in, the Depositary
            ("AGENT MEMBERS") nor any other Persons on whose behalf Agent
            Members may act shall have any rights under this Indenture with
            respect to any Global Debenture registered in the name of the
            Depositary or any nominee thereof, and the Depositary or such
            nominee, as the case may be, may be treated by the Company, the
            Trustee and any agent of the Company or the Trustee as the absolute
            owner and holder of such Global Debenture for all purposes
            whatsoever. Notwithstanding the foregoing, nothing herein shall
            prevent the Company, the Trustee or any agent of the Company or the
            Trustee from giving effect to any written certification, proxy or
            other authorization furnished by the Depositary or such nominee, as
            the case may be, or impair, as between the Depositary, its Agent
            Members and any other Person on whose behalf an Agent Member may
            act, the operation of customary practices of such Persons governing
            the exercise of the rights of a holder of any Debenture.

                  (vi) At such time as all interests in a Global Debenture have
            been redeemed, repurchased, converted, cancelled or exchanged for
            Debentures in certificated form, such Global Debenture shall, upon
            receipt thereof, be cancelled by the Trustee in accordance with
            standing procedures and instructions existing between the Depositary
            and the Custodian. At any time prior to such cancellation, if any
            interest in a Global Debenture is redeemed, repurchased, converted,
            cancelled or exchanged for Debentures in certificated form, the
            principal amount of such Global Debenture shall, in accordance with
            the standing procedures and instructions existing between the
            Depositary and the Custodian, be

                                       23
<PAGE>

      appropriately reduced, and an endorsement shall be made on such Global
      Debenture, by the Trustee or the Custodian, at the direction of the
      Trustee, to reflect such reduction.

      (c) Every Debenture that bears or is required under this Section 2.05(c)
to bear the legend set forth in this Section 2.05(c) (together with any Common
Stock issued upon conversion of the Debentures and required to bear the legend
set forth in Section 2.05(c), collectively, the "RESTRICTED SECURITIES") shall
be subject to the restrictions on transfer set forth in this Section 2.05(c)
(including those set forth in the legend below) unless such restrictions on
transfer shall be waived by written consent of the Company, and the holder of
each such Restricted Security, by such Debenture holder's acceptance thereof,
agrees to be bound by all such restrictions on transfer. As used in Section
2.05(c) and 2.05(d), the term "TRANSFER" encompasses any sale, pledge, loan,
transfer or other disposition whatsoever of any Restricted Security or any
interest therein.

      Until the expiration of the holding period applicable to sales thereof
under Rule 144(k) under the Securities Act (or any successor provision), any
certificate evidencing such Debenture (and all securities issued in exchange
therefor or substitution thereof) and the Common Stock, if any, issued upon
conversion thereof, shall bear a legend in substantially the following form,
unless (a) such Debenture or Common Stock has been sold pursuant to (1) a
registration statement that has been declared effective under the Securities Act
(and that continues to be effective at the time of such transfer) or (2) Rule
144 under the Securities Act or any similar provision then in force, or (b)
otherwise agreed by the Company in writing, with written notice thereof to the
Trustee:

      THIS SECURITY AND THE SHARES OF COMMON STOCK ("COMMON STOCK"), IF ANY,
ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE
SECURITIES LAWS. NEITHER THIS SECURITY, ANY SHARES OF COMMON STOCK ISSUABLE UPON
CONVERSION OF THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN OR THEREIN
MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE
DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS
EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION.

      THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE HEREOF, AGREES TO OFFER,
SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE (THE "RESALE
RESTRICTION TERMINATION DATE") WHICH IS TWO YEARS AFTER THE LAST DATE ON WHICH
THE 2.5% CONVERTIBLE SENIOR SUBORDINATED DEBENTURES DUE 2025 OF GENESIS
HEALTHCARE CORPORATION (THE "COMPANY") WERE ORIGINALLY ISSUED ONLY (A) TO THE
COMPANY OR ANY SUBSIDIARY THEREOF, (B) FOR SO LONG AS THE

                                       24
<PAGE>

SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT
REASONABLY BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" AS DEFINED IN RULE 144A
UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT
OF A QUALIFIED INSTITUTIONAL BUYER TO WHICH NOTICE IS GIVEN THAT THE TRANSFER IS
BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO A REGISTRATION STATEMENT
THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT OR (D) PURSUANT TO
ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES
ACT, SUBJECT TO THE RIGHTS OF THE COMPANY AND THE WITHIN MENTIONED TRUSTEE PRIOR
TO THE REGISTRATION OF ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (B),
(C) or (D) TO REQUIRE A DULY COMPLETED AND SIGNED CERTIFICATE (THE FORM OF WHICH
IS AVAILABLE FROM THE COMPANY OR THE TRUSTEE) AND IN THE CASE OF CLAUSE (D) TO
REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER
INFORMATION SATISFACTORY TO EACH OF THEM, AND IN EACH OF THE FOREGOING CASES, A
CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THE OTHER SIDE OF THIS SECURITY
COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRUSTEE. THIS LEGEND WILL BE
REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION
DATE.

      Any Debenture (or security issued in exchange or substitution therefor) or
such Common Stock as to which such restrictions on transfer shall have expired
in accordance with their terms or as to conditions for removal of the foregoing
legend set forth therein have been satisfied may, upon surrender of such
Debenture or certificates representing such shares of Common Stock for exchange
to the Debenture Registrar or transfer agent of the Common Stock in accordance
with the provisions of this Section 2.05, be exchanged for a new Debenture or
Debentures, of like tenor and aggregate principal amount, or certificates
representing a like number of shares of Common Stock that shall not bear the
restrictive legend required by this Section 2.05(c). If the Restricted Security
surrendered for exchange is represented by a Global Debenture bearing the legend
set forth in this Section 2.05(c), the principal amount of the legended Global
Debenture shall be reduced by the appropriate principal amount and the principal
amount of a Global Debenture without the legend set forth in this Section
2.05(c) shall be increased by an equal principal amount. If a Global Debenture
without the legend set forth in this Section 2.05(c) is not then Outstanding,
the Company shall execute and the Trustee shall authenticate and deliver an
unlegended Global Debenture to the Depositary.

      (d) Any Debenture or Common Stock, if any, issued upon the conversion of a
Debenture that, prior to the expiration of the holding period applicable to
sales thereof under Rule 144(k) under the Securities Act (or any successor
provision), is purchased or owned by the Company or any Affiliate

                                       25
<PAGE>

thereof may not be resold by the Company or such Affiliate unless registered
under the Securities Act or resold pursuant to an exemption from the
registration requirements of the Securities Act in a transaction that results in
such Debentures or Common Stock, as the case may be, no longer being "RESTRICTED
SECURITIES" (as defined under Rule 144).

      (e) The Company and the Trustee shall have no responsibility or obligation
to any Agent Members or any other Person with respect to the accuracy of the
books or records, or the acts or omissions, of the Depositary or its nominee or
of any participant or member thereof, with respect to any ownership interest in
the Debentures, with respect to performance by the Depositary or any Agent
Members of their respective obligations under the rules and procedures governing
their operations or with respect to the delivery to any Agent Member or other
Person (other than the Depositary) of any notice (including any notice of
redemption) or the payment of any amount, under or with respect to such
Debentures. All notices and communications to be given to the Debentureholder
and all payments to be made to Debentureholders under the Debentures shall be
given or made only to or upon the order of the registered Debentureholders
(which shall be the Depositary or its nominee in the case of a Global
Debenture). The rights of beneficial owners in any Global Debenture shall be
exercised only through the Depositary subject to the customary procedures of the
Depositary. The Company and the Trustee may rely and shall be fully protected in
relying upon information furnished by the Depositary with respect to its Agent
Members.

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

      Section 2.06. Mutilated, Destroyed, Lost or Stolen Debentures. In case any
Debenture shall become mutilated or be destroyed, lost or stolen, the Company in
its discretion may execute, and upon the written order of the Company signed by
its Chairman of the Board, Chief Executive Officer, President or any Vice
President, the Treasurer or any Assistant Treasurer or the Secretary or
Assistant Secretary, the Trustee or an authenticating agent appointed by the
Trustee shall authenticate and make available for delivery, a new Debenture,
bearing a number not contemporaneously Outstanding, in exchange and substitution
for the mutilated Debenture, or in lieu of and in substitution for the Debenture
so destroyed, lost or stolen. In every case, the applicant for a substituted
Debenture shall furnish to the Company, to the Trustee and, if applicable, to
such authenticating agent such security or indemnity as may be required by them
to save each of them harmless for any loss, liability, cost or

                                       26
<PAGE>

expense caused by or connected with such substitution, and, in every case of
destruction, loss or theft, the applicant shall also furnish to the Company, to
the Trustee and, if applicable, to such authenticating agent evidence to their
satisfaction of the destruction, loss or theft of such Debenture and of the
ownership thereof.

      Following receipt by the Trustee or such authenticating agent, as the case
may be, of satisfactory security or indemnity and evidence, as described in the
preceding paragraph, the Trustee or such authenticating agent may authenticate
any such substituted Debenture and make available for delivery such Debenture.
Upon the issuance of any substituted Debenture, the Company may require the
payment by the holder of a sum sufficient to cover any tax, assessment or other
governmental charge that may be imposed in relation thereto and any other
expenses connected therewith. In case any Debenture that has matured or is about
to mature or has been called for redemption or has been tendered for redemption
upon a Designated Event (and not withdrawn) or has been surrendered for
repurchase on a Repurchase Date (and not withdrawn) or is to be converted
pursuant to Article 17 shall become mutilated or be destroyed, lost or stolen,
the Company may, instead of issuing a substitute Debenture, pay or authorize the
payment of or convert or authorize the conversion of the same (without surrender
thereof except in the case of a mutilated Debenture), as the case may be, if the
applicant for such payment or conversion shall furnish to the Company, to the
Trustee and, if applicable, to such authenticating agent such security or
indemnity as may be required by them to save each of them harmless for any loss,
liability, cost or expense caused by or in connection with such substitution,
and, in every case of destruction, loss or theft, the applicant shall also
furnish to the Company, the Trustee and, if applicable, any paying agent or
conversion agent evidence to their satisfaction of the destruction, loss or
theft of such Debenture and of the ownership thereof.

      Every substitute Debenture issued pursuant to the provisions of this
Section 2.06 by virtue of the fact that any Debenture is destroyed, lost or
stolen shall constitute an additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Debenture shall be found at any
time, and shall be entitled to all the benefits of (but shall be subject to all
the limitations set forth in) this Indenture equally and proportionately with
any and all other Debentures duly issued hereunder. To the extent permitted by
law, all Debentures shall be held and owned upon the express condition that the
foregoing provisions are exclusive with respect to the replacement or payment or
conversion or redemption or repurchase of mutilated, destroyed, lost or stolen
Debentures and shall preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the contrary
with respect to the replacement or payment or conversion or redemption or
repurchase of negotiable instruments or other securities without their
surrender.

      Section 2.07. Temporary Debentures. Pending the preparation of Debentures
in certificated form, the Company may execute and the Trustee or an

                                       27
<PAGE>

authenticating agent appointed by the Trustee shall, upon the written request of
the Company, authenticate and deliver temporary Debentures (printed or
lithographed). Temporary Debentures shall be issuable in any authorized
denomination, and substantially in the form of the Debentures in certificated
form, but with such omissions, insertions and variations as may be appropriate
for temporary Debentures, all as may be determined by the Company. Every such
temporary Debenture shall be executed by the Company and authenticated by the
Trustee or such authenticating agent upon the same conditions and in
substantially the same manner, and with the same effect, as the Debentures in
certificated form. Without unreasonable delay, the Company will execute and
deliver to the Trustee or such authenticating agent Debentures in certificated
form and thereupon any or all temporary Debentures may be surrendered in
exchange therefor, at each office or agency maintained by the Company pursuant
to Section 6.02 and the Trustee or such authenticating agent shall authenticate
and make available for delivery in exchange for such temporary Debentures an
equal aggregate principal amount of Debentures in certificated form. Such
exchange shall be made by the Company at its own expense and without any charge
therefor. Until so exchanged, the temporary Debentures shall in all respects be
entitled to the same benefits and subject to the same limitations under this
Indenture as Debentures in certificated form authenticated and delivered
hereunder.

      Section 2.08. Cancellation of Debentures. All Debentures surrendered for
the purpose of payment, redemption, repurchase, conversion, exchange or
registration of transfer shall, if surrendered to the Company or any paying
agent or any Debenture Registrar or any conversion agent, be surrendered to the
Trustee and promptly cancelled by it, or, if surrendered to the Trustee, shall
be promptly cancelled by it, and no Debentures shall be issued in lieu thereof
except as expressly permitted by any of the provisions of this Indenture. The
Trustee shall dispose of such cancelled Debentures in accordance with its
customary procedures. If the Company shall acquire any of the Debentures, such
acquisition shall not operate as a redemption, repurchase or satisfaction of the
indebtedness represented by such Debentures unless and until the same are
delivered to the Trustee for cancellation.

      Section 2.09. CUSIP Numbers. The Company in issuing the Debentures 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 Debentureholders;
provided that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Debentures or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Debentures, and any such redemption shall
not be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee of any change in the "CUSIP" numbers.

                                    ARTICLE 3
                     REDEMPTION AND REPURCHASE OF DEBENTURES

      Section 3.01. Redemption of Debentures. The Company may not redeem any
Debentures prior to March 20, 2010. On or after March 20, 2010 but prior to
March 15, 2012, the Company shall have the option to redeem some or all of the
Debentures at any time or from time to time but only if the Closing Price of the
Common Stock for twenty (20) Trading Days within a period of thirty (30)
consecutive Trading Days ending on the Trading Day before the Company provides
the notice required by Section 3.02 hereof exceeds 130% of the Conversion Price
in effect on each such Trading Day, subject to adjustment as provided in Section
17.05. On or after March 15, 2012, and prior to maturity, the Debentures may be
redeemed at any time or from time to time at the option of the Company, in whole
or in part. Upon any redemption pursuant to this Section 3.01, the Company shall
provide the notice required by Section 3.02 hereof (which notice may be revoked
at any time prior to the time at which the Company or the Trustee, as the case
may be, has given such notice to Debentureholders) and shall pay a redemption
price in cash equal to 100% of the principal amount of the Debentures being
redeemed, together with accrued and unpaid Interest and Additional Amounts, if
any, to, but excluding, the date fixed for redemption; provided that if the date
fixed for redemption falls after a record date and on or prior to the
corresponding interest payment date, then the Interest and Additional Amounts,
if any, payable on such interest payment date shall be paid to the holders of
record of the Debentures at the close of business on the applicable record date
instead of the holders surrendering the Debentures for redemption.

      Section 3.02. Notice of Optional Redemption; Selection of Debentures. In
case the Company shall desire to exercise the right to redeem all or, as the
case may be, any part of the Debentures pursuant to Section 3.01, it shall fix a
date for redemption and it or, at its written request (which may be revoked at
any time prior to the time on which the Trustee has given notice to the holders
of the Debentures) received by the Trustee not fewer than forty-five (45) days
prior (or such shorter period of time as may be acceptable to the Trustee) to
the date fixed for redemption, the Trustee in the name of and at the expense of
the Company, shall mail or cause to be mailed a notice of such redemption not
fewer than thirty (30) nor more than sixty (60) days prior to the redemption
date to each holder of Debentures so to be redeemed as a whole or in part at its
last address as the same appears on the Debenture Register; provided that if the
Company shall give such notice, it shall also give written notice of the
redemption date to the Trustee. Such mailing shall be by first class mail. The
notice, if mailed in the manner herein provided, shall be conclusively presumed
to have been duly given, whether or not the holder receives such notice. In any
case, failure to give such notice by mail or any defect in the notice to the
holder of any Debenture designated for redemption as a whole or in part shall
not affect the validity of the proceedings for the redemption of any other
Debenture. Concurrently with, or promptly following, the mailing of any such
notice of redemption, the Company shall issue a press release announcing such
redemption, the form and content of which press

                                       29
<PAGE>

release shall be determined by the Company in its sole discretion. The failure
to issue any such press release or any defect therein shall not affect the
validity of the redemption notice or any of the proceedings for the redemption
of any Debenture called for redemption.

      Each such notice of redemption shall specify the aggregate principal
amount of Debentures to be redeemed, the CUSIP number or numbers, if any, of the
Debentures being redeemed, the date fixed for redemption (which shall be a
Business Day), the redemption price at which Debentures are to be redeemed, the
place or places of payment, that payment will be made upon presentation and
surrender of such Debentures, that Interest and Additional Amounts, if any,
accrued and unpaid to the date fixed for redemption will be paid as specified in
said notice, and that on and after said date Interest and Additional Amounts, if
any, thereon or on the portion thereof to be redeemed will cease to accrue. Such
notice shall also state the current Conversion Rate and the date on which the
right to convert such Debentures pursuant to Article 17 will expire. If fewer
than all the Debentures are to be redeemed, the notice of redemption shall
identify the Debentures to be redeemed (including CUSIP numbers, if any). In
case any Debenture is to be redeemed in part only, the notice of redemption
shall state the portion of the principal amount thereof to be redeemed and shall
state that, on and after the redemption date, upon surrender of such Debenture,
a new Debenture or Debentures in principal amount equal to the unredeemed
portion thereof will be issued.

      On or prior to the redemption date specified in the notice of redemption
given as provided in this Section 3.02, the Company will deposit with the
Trustee or with one or more paying agents (or, if the Company is acting as its
own paying agent, set aside, segregate and hold in trust as provided in Section
6.04) an amount of money in immediately available funds sufficient to redeem on
the redemption date all the Debentures (or portions thereof) so called for
redemption (other than those theretofore surrendered for conversion pursuant to
Article 17) at the appropriate redemption price, together with accrued and
unpaid Interest and Additional Amounts, if any, to, but excluding, the
redemption date; provided that if such payment is made on the redemption date it
must be received by the Trustee or paying agent, as the case may be, by 10:00
a.m. New York City time on such date. The Company shall be entitled to retain
any interest, yield or gain on amounts deposited with the Trustee or any paying
agent pursuant to this Section 3.02 in excess of amounts required hereunder to
pay the redemption price and accrued and unpaid Interest and Additional Amounts,
if any, to, but excluding, the redemption date. If any Debenture called for
redemption is converted pursuant hereto prior to such redemption date, any money
deposited with the Trustee or any paying agent or so segregated and held in
trust for the redemption of such Debenture shall be paid to the Company upon its
written request, or, if then held by the Company, shall be discharged from such
trust. Whenever any Debentures are to be redeemed, the Company will give the
Trustee written notice in the form of an Officers' Certificate not fewer than
forty-five (45) days (or such shorter

                                       30
<PAGE>

period of time as may be acceptable to the Trustee) prior to the redemption date
as to the aggregate principal amount of Debentures to be redeemed.

      If less than all of the Outstanding Debentures are to be redeemed, the
Trustee shall select the Debentures or portions thereof of the Global Debenture
or the Debentures in certificated form to be redeemed (in principal amounts of
$1,000 or multiples thereof) by lot, on a pro rata basis or by another method
the Trustee deems fair and appropriate. If any Debenture selected for partial
redemption is submitted for conversion in part after such selection, the portion
of such Debenture submitted for conversion shall be deemed (so far as may be
possible) to be the portion to be selected for redemption. The Debentures (or
portions thereof) so selected shall be deemed duly selected for redemption for
all purposes hereof, notwithstanding that any such Debenture is submitted for
conversion in part before the mailing of the notice of redemption.

      Upon any redemption of less than all of the Outstanding Debentures, the
Company and the Trustee may (but need not), solely for purposes of determining
the pro rata allocation among such Debentures as are unconverted and Outstanding
at the time of redemption, treat as Outstanding any Debentures surrendered for
conversion during the period of fifteen (15) days next preceding the mailing of
a notice of redemption and may (but need not) treat as Outstanding any Debenture
authenticated and delivered during such period in exchange for the unconverted
portion of any Debenture converted in part during such period.

      Section 3.03. Payment of Debentures Called For Redemption by the Company.
If notice of redemption has been given as provided in Section 3.02, the
Debentures or portion of Debentures with respect to which such notice has been
given shall, unless converted pursuant to Article 17, become due and payable on
the date fixed for redemption and at the place or places stated in such notice
at the applicable redemption price, together with Interest and Additional
Amounts, if any, accrued and unpaid to (but excluding) the redemption date, and
on and after said date (unless the Company shall default in the payment of such
Debentures at the redemption price, together with Interest and Additional
Amounts, if any, accrued to said date) Interest and Additional Amounts, if any,
on the Debentures or portion of Debentures so called for redemption shall cease
to accrue and, after the close of business on the Business Day immediately
preceding the redemption date (unless the Company shall default in the payment
of such Debentures at the redemption price, together with Interest and
Additional Amounts, if any, accrued to said date), such Debentures shall cease
to be convertible pursuant to Article 17 and, except as provided in Section
9.05, to be entitled to any benefit or security under this Indenture, and the
holders thereof shall have no right in respect of such Debentures except the
right to receive the redemption price thereof and accrued and unpaid Interest
and Additional Amounts, if any, to (but excluding) the redemption date. On
presentation and surrender of such Debentures at a place of payment in said
notice specified, the said Debentures or the specified portions thereof shall be

price, together with Interest and Additional Amounts, if any, accrued and unpaid
thereon to, but excluding, the redemption date.

      Upon presentation of any Debenture redeemed in part only, the Company
shall execute and, upon the request of the Company, the Trustee shall
authenticate and make available for delivery to the holder thereof, at the
expense of the Company, a new Debenture or Debentures, of authorized
denominations, in principal amount equal to the unredeemed portion of the

      Section 3.04. [Reserved]

      Section 3.05. Repurchase of Debentures by the Company at Option of Holders
Upon a Designated Event. (a) If there shall occur a Designated Event at any time
prior to maturity of the Debentures, then each Debentureholder shall have the
right, at such holder's option, to require the Company to repurchase all of such
holder's Debentures, or any portion thereof that is a multiple of $1,000
principal amount, for cash on a date designated by the Company (the "DESIGNATED
EVENT REPURCHASE DATE") that is not less than twenty (20) nor more than
thirty-five (35) Business Days after the date of the Designated Event Notice (as
defined in Section 3.05(b)) for such Designated Event (or, if such day is not a
Business Day, the next succeeding Business Day) at a repurchase price equal to
100% of the principal amount thereof, together with accrued and unpaid Interest
and Additional Amounts, if any, to, but excluding, the Designated Event
Repurchase Date; provided that if such Designated Event Repurchase Date falls
after a record date and on or prior to the corresponding interest payment date,
then the Interest and Additional Amounts, if any, payable on such interest
payment date shall be paid to the holders of record of the Debentures at the
close of business on the applicable record date instead of the holders
surrendering the Debentures for repurchase. Notwithstanding the foregoing, no
Debentures may be surrendered for repurchase pursuant to this Section 3.05 in
connection with a merger, consolidation or other transaction effected solely for
the purpose of changing the Company's jurisdiction of incorporation to any other
state within the United States.

      (b) On or before the 20th day after the occurrence of a Designated Event,
the Company or at its written request (which must be received by the Trustee at
least five (5) Business Days prior to the date the Trustee is requested to give
notice as described below, unless the Trustee shall agree in writing to a
shorter period), the Trustee, in the name of and at the expense of the Company,
shall mail or cause to be mailed to all holders of record on the date of the
Designated Event a notice (the "DESIGNATED EVENT NOTICE") of the occurrence of
such Designated Event and of the repurchase right at the option of the holders
arising as a result thereof. Such notice shall be mailed in the manner and with
the

                                       32
<PAGE>

effect set forth in the first paragraph of Section 3.02 (without regard for the
time limits set forth therein). If the Company shall give such notice, the
Company shall also deliver a copy of the Designated Event Notice to the Trustee
at such time as it is mailed to Debentureholders. Concurrently with, or promptly
following, the mailing of any Designated Event Notice, the Company shall issue a
press release announcing such Designated Event referred to in the Designated
Event Notice, the form and content of which press release shall be determined by
the Company in its sole discretion, or (at the Company's sole election) the
Company may publish such information on its website or through such other public
medium as the Company shall use at such time. The failure to issue any such
press release or otherwise publish such information or any defect therein shall
not affect the validity of the Designated Event Notice or any proceedings for
the repurchase of any Debenture that any Debentureholder may elect to have the
Company repurchase as provided in this Section 3.05.

      Each Designated Event Notice shall specify the circumstances constituting
the Designated Event, the Designated Event Repurchase Date, the price at which
the Company shall be obligated to repurchase Debentures, that the holder must
exercise the repurchase right on or prior to the close of business on the
Designated Event Repurchase Date (the "DESIGNATED EVENT EXPIRATION TIME"), that
the holder shall have the right to withdraw any Debentures surrendered prior to
the Designated Event Expiration Time, if the Debentures are then convertible,
that Debentures as to which an Option to Elect Repurchase Upon a Designated
Event has been given may be converted only if the Option to Elect Repurchase
Upon a Designated Event is withdrawn in accordance with the terms of this
Indenture, a description of the procedure that a Debentureholder must follow to
exercise such repurchase right and to withdraw any surrendered Debentures, the
place or places where the holder is to surrender such holder's Debentures, the
amount of Interest and Additional Amounts, if any, accrued and unpaid on each
Debenture to the Designated Event Repurchase Date and the CUSIP number or
numbers of the Debentures (if then generally in use).

      No failure of the Company to give the foregoing notices and no defect
therein shall limit the Debentureholders' repurchase rights or affect the
validity of the proceedings for the repurchase of the Debentures pursuant to
this Section 3.05.

      (c) Repurchases of Debentures under this Section 3.05 shall be made, at
the option of the holder thereof, upon:

            (i) delivery to the Trustee at the Corporate Trust Office of the
      Trustee (or other paying agent appointed by the Company) by a holder of a
      duly completed and executed notice (the "OPTION TO ELECT REPURCHASE UPON A
      DESIGNATED EVENT") in the form set forth on the reverse of the Debenture
      prior to the Designated Event Expiration Time; and

                                       33
<PAGE>

            (ii) delivery or book-entry transfer of the Debentures to the
      Trustee (or other paying agent appointed by the Company) at any time
      simultaneous to or after delivery of the Option to Elect Repurchase Upon a
      Designated Event (together with all necessary endorsements) at the
      Corporate Trust Office of the Trustee (or other paying agent appointed by
      the Company) in the Borough of Manhattan as provided in Section 6.02, such
      delivery being a condition to receipt by the holder of the repurchase
      price therefor; provided that such repurchase price shall be so paid
      pursuant to this Section 3.05 only if the Debenture so delivered to the
      Trustee (or other paying agent appointed by the Company) shall conform in
      all respects to the description thereof in the related Option to Elect
      Repurchase Upon a Designated Event.

      The Company shall purchase from the holder thereof, pursuant to this
Section 3.05, a portion of a Debenture, if the principal amount of such portion
is $1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply
to the purchase of all of a Debenture also apply to the purchase of such portion
of such Debenture.

      Upon presentation of any Debenture repurchased in part only, the Company
shall execute and, upon the Company's written direction to the Trustee, the
Trustee shall authenticate and make available for delivery to the holder
thereof, at the expense of the Company, a new Debenture or Debentures, of
authorized denominations, in aggregate principal amount equal to the portion of
the Debentures presented that was not repurchased.

      Notwithstanding anything herein to the contrary, any holder delivering to
the Trustee (or other paying agent appointed by the Company) the Option to Elect
Repurchase Upon a Designated Event contemplated by this Section 3.05 shall have
the right to withdraw such Option to Elect Repurchase Upon a Designated Event at
any time prior to the Designated Event Expiration Time by delivery of a written
notice of withdrawal to the Trustee (or other paying agent appointed by the
Company) in accordance with Section 3.05(d) below. Debentures in respect of
which an Option to Elect Repurchase Upon a Designated Event has been given by
the holder thereof may not be converted pursuant to Article 17 hereof on or
after the date of the delivery of such Option to Elect Repurchase Upon a
Designated Event unless such Option to Elect Repurchase Upon a Designated Event
has first been validly withdrawn.

      The Trustee (or other paying agent appointed by the Company) shall
promptly notify the Company of the receipt by it of any Option to Elect
Repurchase Upon a Designated Event or written notice of withdrawal thereof.

      For a Debenture, other than a Global Debenture, to be so repurchased at
the option of the holder, the Company must receive at the office or agency of
the Company maintained for that purpose or, at the option of such holder, the
Corporate Trust Office, such Debenture with the Option to Elect Repurchase

                                       34
<PAGE>

Upon A Designated Event on the reverse thereof duly completed, together with
such Debentures duly endorsed for transfer, on or before the Designated Event
Expiration Time. All questions as to the validity, eligibility (including time
of receipt) and acceptance of any Debenture for repurchase shall be determined
by the Company, whose determination shall be final and binding absent manifest
error.

      (d) An Option to Elect Repurchase Upon a Designated Event may be withdrawn
by means of a written notice of withdrawal delivered to the Corporate Trust
Office of the Trustee (or other paying agent appointed by the Company) in
accordance with the Option to Elect Repurchase Upon a Designated Event at any
time prior to the Designated Event Expiration Time, specifying:

            (i) the principal amount of the Debenture with respect to which such
      notice of withdrawal is being submitted,

            (ii) the certificate number, if any, of the Debenture in respect of
      which such notice of withdrawal is being submitted, or the appropriate
      Depositary information if the Debenture in respect of which such notice of
      withdrawal is being submitted is represented by a Global Debenture, and

            (iii) the principal amount, if any, of such Debenture that remains
      subject to the original Option to Elect Repurchase Upon a Designated
      Event.

      (e) On or prior to the Designated Event Repurchase Date, the Company shall
deposit with the Trustee or with one or more paying agents (or, if the Company
is acting as its own paying agent, set aside, segregate and hold in trust as
provided in Section 6.04) an amount of money sufficient to repurchase on the
Business Day immediately preceding the Designated Event Repurchase Date all the
Debentures to be repurchased on such date at the appropriate repurchase price,
together with accrued and unpaid Interest and Additional Amounts, if any, to,
but excluding, the Designated Event Repurchase Date; provided that if such
payment is made on the Designated Event Repurchase Date it must be received by
the Trustee or paying agent, as the case may be, by 10:00 a.m. New York City
time, on such date. Payment for Debentures surrendered for repurchase (and not
withdrawn) prior to the Designated Event Expiration Time will be made promptly
(but in no event more than five (5) Business Days) following the later of (x)
the Business Day immediately following the Designated Event Repurchase Date, and
(y) the time of book-entry transfer or delivery of the Debenture surrendered for
repurchase, by (i) mailing checks for the amount payable to the holders of such
Debentures entitled thereto as they shall appear in the Debenture Register or
(ii) on any Global Debenture by wire transfer of immediately available funds to
the account of the Depositary or its nominee.

      If on the Business Day immediately following the Designated Event
Repurchase Date the Trustee or other paying agent appointed by the Company, or

                                       35
<PAGE>

the Company if the Company is acting as the paying agent, holds money sufficient
to repurchase all the Debentures or portions thereof that are to be purchased as
of the Designated Event Repurchase Date, then, on and after such date (i) the
Debentures will cease to be Outstanding, (ii) Interest and Additional Amounts,
if any, on the Debentures will cease to accrue, and (iii) all other rights of
the holders of such Debentures will terminate, whether or not book-entry
transfer of the Debentures has been made or the Debentures have been delivered
to the Trustee or paying agent, other than the right to receive the repurchase
price upon delivery of the Debentures.

      (f) [Reserved.]

      (g) The Company will comply with the provisions of Rule 13e-4, Rule 14e-1
and any other tender offer rules under the Exchange Act to the extent applicable
and file a Schedule TO or any other required schedule or form under the Exchange
Act to the extent then applicable in connection with the repurchase rights of
the holders of Debentures in the event of a Designated Event.

price of 100% of the principal amount, plus any accrued and unpaid Interest and
Additional Amounts, if any, to, but excluding, the Repurchase Date; provided
that if such Repurchase Date falls after a record date and on or prior to the
corresponding interest payment date, then the Interest and Additional Amounts,
if any, payable on such interest payment date shall be paid to the holders of
record of the Debentures at the close of business on the applicable record date
instead of the holders surrendering the Debentures for repurchase. Repurchases
of Debentures under this Section 3.06 shall be made, at the option of the holder
thereof, upon:

      (a) delivery to the Trustee (or other paying agent appointed by the
Company) by a holder of a duly completed and executed notice (the "REPURCHASE
NOTICE") in the form set forth on the reverse of the Debenture during the period
beginning at any time from the opening of business on the date that is twenty
(20) Business Days prior to the Repurchase Date until the close of business on
the Repurchase Date; and

agent appointed by the Company) in the Borough of Manhattan as provided in
Section 6.02, such delivery being a condition to receipt by the holder of the
purchase price therefor; provided that such purchase price shall be so paid
pursuant to this Section 3.06 only if the Debenture so delivered to the Trustee
(or other paying

                                       36
<PAGE>

agent appointed by the Company) shall conform in all respects to the description
thereof in the related Repurchase Notice.

      The Company shall purchase from the holder thereof, pursuant to this
Section 3.06, a portion of a Debenture, if the principal amount of such portion
is $1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply
to the purchase of all of a Debenture also apply to the purchase of such portion
of such Debenture.

      Upon presentation of any Debenture repurchased in part only, the Company
shall execute and, upon the Company's written direction to the Trustee, the
Trustee shall authenticate and make available for delivery to the holder
thereof, at the expense of the Company, a new Debenture or Debentures, of
authorized denominations, in aggregate principal amount equal to the portion of
the Debentures presented that was not repurchased.

      Any purchase by the Company contemplated pursuant to the provisions of
this Section 3.06 shall be consummated by the delivery of the consideration to
be received by the holder promptly following the later of the Business Day

Repurchase Notice at any time prior to the close of business on the Repurchase
Date by delivery of a written notice of withdrawal to the Trustee (or other
paying agent appointed by the Company) in accordance with Section 3.08.

      The Trustee (or other paying agent appointed by the Company) shall
promptly notify the Company of the receipt by it of any Repurchase Notice or
written notice of withdrawal thereof.

      (c) The Company will comply with the provisions of Rule 13e-4, Rule 14e-1

other paying agent appointed by the Company) of the Repurchase Notice specified

required by Section 3.06. Debentures in respect of which a Repurchase Notice has
been given by the holder thereof may not be converted pursuant to Article 17
hereof on or after the date of the delivery of such Repurchase Notice unless
such Repurchase Notice has first been validly withdrawn.

thereon, held by them for the payment of the repurchase price; provided that to
the extent that the aggregate amount of cash deposited by the Company pursuant

price or purchase price, as the case may be, of the Debentures or portions
thereof that the Company is obligated to redeem or purchase as of the redemption

      Section 4.01. Agreement To Subordinate. Each of the Company and the
Subsidiary Guarantors agrees, and each holder by accepting a Debenture agrees,
that the Indebtedness evidenced by the Debentures and the Subsidiary Guarantees
and the payment of the principal amount and Interest and Additional Amounts, if
any, on all Debentures and all other amounts and claims owing on and with
respect to each and all of the Debentures (including, but not limited to, the

accordance with Section 3.02 or the repurchase price with respect to Debentures
submitted for repurchase in accordance with Section 3.05 or Section 3.06, as the

payment, to the extent and in the manner provided in this Article 4, to the
prior payment in full in cash of all Senior Indebtedness (whether outstanding on
the date hereof or hereafter created, incurred, assumed or guaranteed), and that
the subordination is for the benefit of the holders of Senior Indebtedness. The
Debentures will be pari passu in right of payment to all Senior Subordinated
Indebtedness of the Company and the Subsidiary Guarantors and senior in right of
payment to all Subordinated Indebtedness of the Company and such Subsidiary
Guarantors.

      Section 4.02. Liquidation; Dissolution; Bankruptcy. Upon any distribution
to creditors of the Company or a Subsidiary Guarantor in a liquidation or
dissolution of the Company or such Subsidiary Guarantor, in a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to the
Company or a Subsidiary Guarantor or their property, in an assignment for the
benefit of creditors or in any marshalling of the assets and liabilities of the
Company or a Subsidiary Guarantor, the holders of Senior Indebtedness shall be
entitled to receive payment in full in cash or other payment satisfactory to
holders of such Obligations due in respect of such Senior Indebtedness
(including interest after the commencement of any such proceeding at the rate
specified in the applicable Senior Indebtedness) before the holders of
Debentures will be entitled to receive any payment with respect to the
Debentures or the Subsidiary Guarantees, and until all Obligations with respect
to Senior Indebtedness are paid in full in cash or in other payment satisfactory
to such holders, any distribution to which the holders of Debentures would be
entitled shall be made to the holders of Senior Indebtedness (except, in each
case, that holders of Debentures may receive Permitted Junior Securities).

      Section 4.03. Default on Designated Senior Indebtedness. The Company may
not make any payment in respect of the Debentures, nor may the Company acquire
or redeem any Debentures if:

                                       41
<PAGE>

      without limitation, upon any acceleration of the maturity thereof) occurs
      and is continuing; or

            (2) any other default occurs and is continuing on any series of
      Designated Senior Indebtedness that permits holders of that series of
      Designated Senior Indebtedness to accelerate its maturity and the Trustee
      receives a written notice of such default (a "PAYMENT BLOCKAGE NOTICE")
      from the Company, the administrative agent for the lenders under the
      Senior Credit Agreement or the holders of, or the representative for, any
      Designated Senior Indebtedness.

      Payments on, and redemption of, the Debentures may and will be resumed, if
so permitted by the other Sections of the Indenture:

            (1) in the case of a payment default, upon the date on which such
      default is cured or waived or ceases to exist; and

            (2) in the case of a nonpayment default, upon the earlier of (x) the
      date on which such nonpayment default is cured or waived (so long as no
      other default exists), (y) 179 days after the date on which the applicable
      Payment Blockage Notice is received, or (z) the date on which the Trustee
      receives notice from a representative of Designated Senior Indebtedness
      rescinding such Payment Blockage Notice, unless, in each case, the
      maturity of any Designated Senior Indebtedness has been accelerated.

      No new Payment Blockage Notice may be delivered unless and until:

            (1) 360 days have elapsed since the delivery of the immediately
      prior Payment Blockage Notice; and

            (2) all scheduled payments of principal, Interest, and Additional
      Amounts, if any, on the Debentures that have come due have been paid in
      full in cash.

      No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee will be, or be made, the
basis for a subsequent Payment Blockage Notice unless such default has been
cured or waived for a period of not less than 90 days.

      Section 4.04. Acceleration of Debentures. If payment of the Debentures is
accelerated because of an Event of Default, the Company shall promptly notify
holders of Senior Indebtedness of the acceleration.

      Section 4.05. When Distribution Must Be Paid Over. In the event that the
Trustee or any holder receives any payment of any Obligations with respect to
the Debentures and the Subsidiary Guarantees at a time when the Trustee or such
holder, as applicable, has actual knowledge that such payment is prohibited by

                                       42
<PAGE>

Article 4 hereof, such payment shall be held by the Trustee or such holder, in
trust for the benefit of, and shall be paid forthwith over and delivered, upon
proper written request, to, the holders of Senior Indebtedness or their
representative under the agreement pursuant to which Senior Indebtedness may
have been issued, as their respective interests may appear, which with respect
to any and all Indebtedness outstanding under the Senior Credit Agreement, shall
mean the agent for such holders, for application to the payment of all
Obligations with respect to Senior Indebtedness remaining unpaid to the extent
necessary to pay such Obligations in full in accordance with their terms, after
giving effect to any concurrent payment or distribution to or for the holders of
Senior Indebtedness.

      With respect to the holders of Senior Indebtedness, the Trustee undertakes
to perform only such obligations on the part of the Trustee as are specifically
set forth in this Article 4, and no implied covenants or obligations with
respect to the holders of Senior Indebtedness shall be read into this Indenture
against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty
to the holders of Senior Indebtedness, and shall not be liable to any such
holders if the Trustee shall pay over or distribute to or on behalf of holders
or the Company or any other Person money or assets to which any holders of
Senior Indebtedness shall be entitled by virtue of this Article 4, except if
such payment is made as a result of the willful misconduct or negligence of the
Trustee.

      Section 4.06. Notice By Company. The Company shall promptly notify the
Trustee and the paying agent of any facts known to the Company that would cause
a payment of any Obligations with respect to the Debentures and the Subsidiary
Guarantees to violate this Article 4, but failure to give such notice shall not
affect the subordination of the Debentures and the Subsidiary Guarantees to the
Senior Indebtedness as provided in this Article 4.

      The Trustee shall be entitled to rely on the delivery to it of a written
notice by a person representing himself to be a holder of Senior Indebtedness
(or a trustee or agent on behalf of such holder) to establish that such notice
has been given by a holder of Senior Indebtedness (or a trustee or agent on
behalf of any such holder). In the event that the Trustee determines in good
faith that further evidence is required with respect to the right of any Person
as holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article 4, the Trustee may request such person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such person, the extent to which such person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article 4, and if such
evidence is not furnished, the Trustee may defer any payment which it may be
required to make for the benefit of such person pursuant to the terms of this
Indenture pending judicial determination as to the rights of such Person to
receive such payment.

      Section 4.07. Subrogation. After all Senior Indebtedness is paid in full
in cash and until the Debentures are paid in full, holders of Debentures shall
be

                                       43
<PAGE>

subrogated (equally and ratably with all other Indebtedness ranking pari
passu with the Debentures) to the rights of holders of Senior Indebtedness to
receive distributions applicable to Senior Indebtedness to the extent that
distributions otherwise payable to the holders of Debentures have been applied
to the payment of Senior Indebtedness. A distribution made under this Article 4
to holders of Senior Indebtedness that otherwise would have been made to holders
of Debentures is not, as between the Company and holders, a payment by the
Company or the Subsidiary Guarantors on the Debentures and the Subsidiary
Guarantees.

      Section 4.08. Relative Rights. This Article 4 defines the relative rights
of holders of Debentures and holders of Senior Indebtedness. Nothing in this
Indenture shall:

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

            (2) affect the relative rights of holders of Debentures and
      creditors of the Company other than their rights in relation to holders of
      Senior Indebtedness; or

            (3) prevent the Trustee or any holder of Debentures from exercising
      its available remedies upon a Default or Event of Default, subject to the
      rights of holders and owners of Senior Indebtedness to receive
      distributions and payments otherwise payable to holders of Debentures.

      If the Company fails because of this Article 4 to pay the principal amount
of the Debentures, Interest, Additional Amounts, if any, the redemption price
with respect to the Debentures to be called for redemption in accordance with
Section 3.02 or the repurchase price with respect to Debentures submitted for
repurchase in accordance with Section 3.05 or Section 3.06, as the case may be,
as provided in this Indenture as and when the same shall become due and payable
in accordance with their terms, such failure is still a Default or Event of
Default.

      Section 4.09. Subordination May Not Be Impaired By Company. No right of
any holder of Senior Indebtedness to enforce the subordination of the
Indebtedness evidenced by the Debentures shall be impaired by any act or failure
to act by the Company or any holder or by the failure of the Company or any
holder to comply with this Indenture.

      Section 4.10. Distribution Or Notice To Representative. Whenever a
distribution is to be made or a notice given to holders of Senior Indebtedness,
the distribution may be made and the notice given to their representative or
agent.

                                       44
<PAGE>

      Upon any payment or distribution of assets of the Company or the
Subsidiary Guarantors referred to in this Article 4, the Trustee and the holders
of Debentures shall be entitled to rely upon any order or decree made by any
court of competent jurisdiction or upon any certificate of such representative
or of the liquidating trustee or agent or other Person making any distribution
to the Trustee or to the holders of Debentures for the purpose of ascertaining
the Persons entitled to participate in such distribution, the holders of the
Senior Indebtedness and other Indebtedness of the Company and the Subsidiary
Guarantors, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article 4.

      Section 4.11. Rights of Trustee and Paying Agent. Notwithstanding the
provisions of this Article 4 or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts that
would prohibit the making of any payment or distribution by the Trustee, and the
Trustee and the paying agent may continue to make payments on the Debentures,
unless the Trustee shall have received at its Corporate Trust Office of the
Trustee at least three Business Days prior to the date of such payment written
notice of facts that would cause the payment of any Obligations with respect to
the Debentures to violate this Article 4. Only the Company or a representative
may give the notice. Nothing in this Article 4 shall impair the claims of, or
payments to, the Trustee under or pursuant to Section 9.06 hereof.

      The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have if it were not Trustee. Any
agent may do the same with like rights.

      Section 4.12. Authorization to Effect Subordination. Each holder of
Debentures, by the holder's acceptance thereof, authorizes and directs the
Trustee on such holder's behalf to take such action as may be necessary or
appropriate to effectuate the subordination as provided in this Article 4, and
appoints the Trustee to act as such holder's attorney-in-fact for any and all
such purposes. If the Trustee does not file a proper proof of claim or proof of
debt in the form required in any proceeding referred to in Section 8.02 hereof
at least thirty (30) days before the expiration of the time to file such claim,
the credit agents are hereby authorized to file an appropriate claim for and on
behalf of the holders of the Debentures.

      Section 4.13. Amendments. The provisions of this Article 4 shall not be
amended or modified without the written consent of the holders of at least 75%
in aggregate principal amount of the Debentures then Outstanding if such
amendment would adversely affect the rights of holders of Debentures.

      Section 4.14. Payment Permitted If No Default. Nothing contained in this
Article 4 or any other provision relating to subordination elsewhere in this
Indenture or in any of the Debentures shall prevent the Company, except in the
circumstances described in Section 4.02 and Section 4.03, from making payments

                                       45
<PAGE>

at any time of the principal amount of the Debentures, Interest, Additional
Amounts, if any, the redemption price with respect to the Debentures to be
called for redemption in accordance with Section 3.02 or the repurchase price
with respect to Debentures submitted for repurchase in accordance with Section
3.05 or Section 3.06, as the case may be, as provided in this Indenture.

      Section 4.15. No Senior Subordinated Indebtedness. Neither the Company
nor any Subsidiary Guarantor shall, directly or indirectly, create, incur,
issue, assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to any Indebtedness that is subordinate
or junior in right of payment to any Senior Indebtedness and senior in right of
payment to the Debentures or the Subsidiary Guarantees, as the case may be.

                                    ARTICLE 5
                              SUBSIDIARY GUARANTEES

      Section 5.01. Subsidiary Guarantees. (a) Subject to this Article 5 and
the subordination provisions of Article 4, each of the Subsidiary Guarantors
hereby, jointly and severally, unconditionally guarantees, during the Guarantee
Period, to each holder of a Debenture authenticated and delivered by the Trustee
and to the Trustee and its successors and assigns, irrespective of the validity
and enforceability of this Indenture, the Debentures or the Obligations of the
Company hereunder or thereunder, that:

            (1) the principal of, and Interest and Additional Amounts, if any,
      on, the Debentures will be promptly paid in full when due, whether at
      maturity, by acceleration, redemption or otherwise, and Interest on the
      overdue principal and Interest on any overdue Interest on the Debentures,
      if any, if lawful, and all other obligations of the Company to the holders
      or the Trustee hereunder or thereunder will be promptly paid in full or
      performed (including, without limitation, the Company's obligation to
      deliver cash and Common Stock, if any, or shares of stock, other
      securities or other property or assets upon conversion of a Debenture
      pursuant to Article 17), all in accordance with the terms hereof and
      thereof; and

            (2) in case of any extension of time of payment or renewal of any
      Debentures or any of such other Obligations, that same will be promptly
      paid in full when due or performed in accordance with the terms of the
      extension or renewal, whether at stated maturity, by acceleration or
      otherwise.

      Failing payment when due of any amount so Guaranteed or any performance so
Guaranteed for whatever reason, the Subsidiary Guarantors will be jointly and
severally obligated to pay the same immediately. Each Subsidiary Guarantor
agrees that this is a Guarantee of payment and not a Guarantee of collection.

                                       46
<PAGE>

      (b) Each Subsidiary Guarantor hereby agrees that its obligations hereunder
are unconditional, irrespective of the validity, regularity or enforceability of
the Debentures or this Indenture, the absence of any action to enforce the same,
any waiver or consent by any holder of the Debentures with respect to any
provisions hereof or thereof, the recovery of any judgment against the Company,
any action to enforce the same or any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a Subsidiary Guarantor.
Each Subsidiary Guarantor hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of insolvency or bankruptcy
of the Company, any right to require a proceeding first against the Company,
protest, notice and all demands whatsoever and covenants that this Subsidiary
Guarantee will not be discharged except by complete performance of the
obligations contained in the Debentures and this Indenture.

      (c) If any holder or the Trustee is required by any court or otherwise to
return to the Company, the Subsidiary Guarantors or any custodian, trustee,
liquidator or other similar official acting in relation to either the Company or
the Subsidiary Guarantors, any amount paid by the Company or any Subsidiary
Guarantor either to the Trustee or such holder, this Subsidiary Guarantee, to
the extent theretofore discharged, will be reinstated in full force and effect.

      (d) Each Subsidiary Guarantor agrees that it will not be entitled to any
right of subrogation in relation to the holders in respect of any Obligations
Guaranteed hereby until payment in full of all Obligations Guaranteed hereby.
Each Subsidiary Guarantor further agrees that, as between the Subsidiary
Guarantors, on the one hand, and the holders and the Trustee, on the other hand,
(1) the maturity of the Obligations Guaranteed hereby may be accelerated as
provided in Article 8 hereof for the purposes of this Subsidiary Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Obligations Guaranteed hereby, and (2) in the
event of any declaration of acceleration of such obligations as provided in
Article 8 hereof, such obligations (whether or not due and payable) will
forthwith become due and payable by the Subsidiary Guarantors for the purpose of
this Subsidiary Guarantee. The Subsidiary Guarantors will 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 the Subsidiary
Guarantee.

      Section 5.02. Limitation on Subsidiary Guarantor Liability. Each
Subsidiary Guarantor, and by its acceptance of Debentures, each holder, hereby
confirms that it is the intention of all such parties that this Subsidiary
Guarantee of such Subsidiary Guarantor not constitute a fraudulent transfer or
conveyance for purposes of Title II of the United States Code, as amended, the
Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any
similar federal or state law to the extent applicable to any Subsidiary
Guarantee. To effectuate the foregoing intention, the holders and the Subsidiary
Guarantors hereby irrevocably agree that the obligations of such Subsidiary
Guarantor shall be limited to the maximum amount that will, after giving effect
to such maximum

                                       47
<PAGE>

amount and all other contingent and fixed liabilities of such Subsidiary
Guarantor that are relevant under such laws, and after giving effect to any
collections from, rights to receive contribution from or payments made by or on
behalf of any other Subsidiary Guarantor in respect of the obligations of such
other Subsidiary Guarantor under this Article 5, result in the obligations of
such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a
fraudulent transfer or conveyance.

      Section 5.03. Execution and Delivery of the Subsidiary Guarantee. To
evidence its Subsidiary Guarantee set forth in Section 5.01, each Subsidiary
Guarantor hereby agrees that the Subsidiary Guarantee substantially in the form
attached to the Indenture as Exhibit B will be endorsed by an officer of such
Subsidiary Guarantor on each Debenture authenticated and delivered by the
Trustee and that this Indenture will be executed on behalf of such Subsidiary
Guarantor by one of its executive officers.

      Each Subsidiary Guarantor hereby agrees that its Subsidiary Guarantee set
forth in Section 5.01 will remain in full force and effect notwithstanding any
failure to endorse such Subsidiary Guarantee.

      If an executive officer whose signature is on this Indenture or on the
Subsidiary Guarantee no longer holds that office at the time the Trustee
authenticates the Debenture on which a Subsidiary Guarantee is endorsed, the
Subsidiary Guarantee will be valid nevertheless.

      The delivery of any Debenture by the Trustee, after the authentication
thereof hereunder, will constitute due delivery of the Subsidiary Guarantee set
forth in this Indenture on behalf of the Subsidiary Guarantors.

      In the event that the Company creates or acquires a Subsidiary during the
Guarantee Period, if required by Section 6.10 hereof, the Company will cause
such Subsidiary to comply with the provisions of Section 6.10 hereof and this
Article 5, to the extent applicable.

      Section 5.04. Release of Subsidiary Guarantors from Obligations. (a) Upon
the expiration of the Guarantee Period, each Subsidiary Guarantor shall be
released and relieved of any obligations under its Subsidiary Guarantee without
any further action required on the part of the Company, the Subsidiary
Guarantors, the Trustee or any holder.

      (b) If all Outstanding Debentures are satisfied and discharged in
accordance with the terms of the Indenture, then each Subsidiary Guarantor shall
be released and relieved of any obligations under its Subsidiary Guarantee
without any further action required on the part of the Company, the Subsidiary
Guarantors, the Trustee or any holder.

      (c) If, during the Guarantee Period, the Company designates any Restricted
Subsidiary that is a Subsidiary Guarantor as an Unrestricted Subsidiary

                                       48
<PAGE>

in accordance with Section 6.11 of this Indenture, then such Subsidiary
Guarantor shall be released and relieved of any Obligations under its Subsidiary
Guarantee by executing a supplemental indenture and providing the Trustee with
an Officer's Certificate and an Opinion of Counsel satisfactory to the Trustee
that such supplemental indenture has been duly authorized, executed and
delivered by such Subsidiary Guarantor and constitutes a valid, binding and
enforceable obligation of such Subsidiary Guarantor.

      If, during the Guarantee Period, the Company designates an Unrestricted
Subsidiary as a Restricted Subsidiary in accordance with Section 6.11 of this
Indenture, then such Restricted Subsidiary shall become a Subsidiary Guarantor
and execute a supplemental indenture and deliver an Officer's Certificate and an
Opinion of Counsel satisfactory to the Trustee within 10 Business Days of the
date on which it was so designated that such supplemental indenture has been
duly authorized, executed and delivered by such Restricted Subsidiary and
constitutes a valid, binding and enforceable obligation of such Restricted
Subsidiary.

      (d) Upon the full and unconditional release of its Guarantee by a
Subsidiary Guarantor under the Senior Subordinated Notes due 2013, then such
Subsidiary Guarantor shall be released and relieved of any Obligations under its
Subsidiary Guarantee by executing a supplemental indenture and providing the
Trustee with an Officer's Certificate and an Opinion of Counsel that such
supplemental indenture has been duly authorized, executed and delivered by such
Subsidiary Guarantor and constitutes a valid, binding and enforceable obligation
of such Subsidiary Guarantor; provided, however, that in the event that any such
Subsidiary thereafter, but during the Guarantee Period, Guarantees any
Indebtedness of the Company under any Senior Subordinated Indebtedness or
Subordinated Indebtedness (or if any released Guarantee under any the Senior
Subordinated Notes due 2013 is reinstated or renewed), then such Subsidiary
shall be required to be a Subsidiary Guarantor by executing a supplemental
indenture and providing the Trustee with an Officer's Certificate and an Opinion
of Counsel satisfactory to the Trustee within 10 Business Days of the date on
which it provided any such other Guarantee that such supplemental indenture has
been duly authorized, executed and delivered by such Subsidiary and constitutes
a valid, binding and enforceable obligation of such Subsidiary.

      (e) Any Subsidiary Guarantor not released from its obligations under its
Subsidiary Guarantee shall remain liable until the expiration of the Guarantee
Period for the full amount of principal of and interest on the Debentures and
for the other obligations of any Subsidiary Guarantor under this Indenture as
provided in this Article 5.

      Section 5.05. Contribution. In order to provide for just and equitable
contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree,
inter se, that in the event any payment or distribution is made by any
Subsidiary Guarantor (a "FUNDING GUARANTOR") under the Subsidiary Guarantees,
such

                                       49
<PAGE>

Funding Guarantor shall be entitled to a contribution from all other Subsidiary
Guarantors in a pro rata amount, based on the net assets of each Subsidiary
Guarantor (including the Funding Guarantor), determined in accordance with GAAP,
subject to Section 5.02, for all payments, damages and expenses incurred by such
Funding Guarantor in discharging the Company's obligations with respect to the
Debentures or any other Subsidiary Guarantor's obligations with respect to the
Subsidiary Guarantees.

                                    ARTICLE 6
        PARTICULAR COVENANTS OF THE COMPANY AND THE SUBSIDIARY GUARANTORS

      Section 6.01. Payment of Principal, Interest and Additional Amounts. The
Company covenants and agrees that it will duly and punctually pay or cause to be
paid the principal of (including the redemption price upon redemption or the
repurchase price upon repurchase, in each case pursuant to Article 3), Interest
on, and Additional Amounts, if any, on, each of the Debentures at the places, at
the respective times and in the manner provided herein and in the Debentures.

      Section 6.02. Maintenance of Office or Agency. The Company will maintain
an office or agency in the Borough of Manhattan, the City of New York, where the
Debentures may be surrendered for registration of transfer or exchange or for
presentation for payment or for conversion, redemption or repurchase and where
notices and demands to or upon the Company in respect of the Debentures and this
Indenture may be served. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or
agency not designated or appointed by the Trustee. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office or the
corporate trust office of the Trustee in The Borough of Manhattan, which office
is located at: The Bank of New York, 101 Barclay Street, Fl. 21W, New York, NY
10286, Attention: Corporate Trust Department.

      The Company may also from time to time designate co-registrars and one or
more offices or agencies where the Debentures may be presented or surrendered
for any or all such purposes and may from time to time rescind such
designations. The Company will give prompt written notice 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 Trustee as paying agent,
Debenture Registrar, Custodian and conversion agent, and each of the Corporate
Trust Office and the office or agency of the Trustee in The Borough of Manhattan
shall be considered as one such office or agency of the Company for each of the
aforesaid purposes.

                                       50
<PAGE>

      So long as the Trustee is the Debenture Registrar, the Trustee agrees to
mail, or cause to be mailed, the notices set forth in Section 9.10(a) and the
third paragraph of Section 9.11. If co-registrars have been appointed in
accordance with this Section, the Trustee shall mail such notices only to the
Company and the holders of Debentures it can identify from its records.

      Section 6.03. Appointments to Fill Vacancies in Trustee's Office. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 9.10, a Trustee, so that there
shall at all times be a Trustee hereunder.

      Section 6.04. Provisions as to Paying Agent. (a) If the Company shall
appoint a paying agent other than the Trustee, or if the Trustee shall appoint
such a paying agent, the Company will cause such paying agent to execute and
deliver to the Trustee an instrument in which such agent shall agree with the
Trustee, subject to the provisions of this Section 6.04:

            (1) that it will hold all sums held by it as such agent for the
      payment of the principal of, Interest on, or Additional Amounts, if any,
      on, the Debentures (whether such sums have been paid to it by the Company
      or by any other obligor on the Debentures) in trust for the benefit of the
      holders of the Debentures;

            (2) that it will give the Trustee notice of any failure by the
      Company (or by any other obligor on the Debentures) to make any payment of
      the principal of, Interest on, and Additional Amounts, if any, on the
      Debentures when the same shall be due and payable; and

            (3) that at any time during the continuance of an Event of Default,
      upon request of the Trustee, it will forthwith pay to the Trustee all sums
      so held in trust.

      The Company shall, on or before each due date of the principal of,
Interest on, or Additional Amounts, if any, on, the Debentures, deposit with the
paying agent a sum (in funds that are immediately available on the due date for
such payment) sufficient to pay such principal, Interest or Additional Amounts,
as the case may be, and (unless such paying agent is the Trustee) the Company
will promptly notify the Trustee of any failure to take such action; provided
that if such deposit is made on the due date, such deposit shall be received by
the paying agent by 10:00 a.m. New York City time, on such date.

      (b) If the Company shall act as its own paying agent, it will, on or
before each due date of the principal of, Interest on, or Additional Amounts, if
any, on, the Debentures, set aside, segregate and hold in trust for the benefit
of the holders of the Debentures a sum sufficient to pay such principal,
Interest or Additional Amounts so becoming due and will promptly notify the
Trustee of any failure to take such action and of any failure by the Company (or
any other

                                       51
<PAGE>

obligor under the Debentures) to make any payment of the principal of, Interest
on, or Additional Amounts, if any, on, the Debentures when the same shall become
due and payable.

      (c) Anything in this Section 6.04 to the contrary notwithstanding, the
Company may, at any time, for the purpose of obtaining a satisfaction and
discharge of this Indenture, or for any other reason, pay or cause to be paid to
the Trustee all sums held in trust by the Company or any paying agent hereunder
as required by this Section 6.04, such sums to be held by the Trustee upon the
trusts herein contained and upon such payment by the Company or any paying agent
to the Trustee, the Company or such paying agent shall be released from all
further liability with respect to such sums.

      The Trustee shall not be responsible for the actions of any other paying

cause to be done all things necessary to preserve and keep in full force and
effect its corporate existence.

      Section 6.06. Rule 144A Information Requirement. Within the period prior

designated by such holder or beneficial holder, the information required
pursuant to Rule 144A(d)(4) under the Securities Act upon the request of any
holder or beneficial holder of the Debentures or such Common Stock and it will
take such further action as any holder or beneficial holder of such Debentures
or such Common Stock may reasonably request, all to the extent required from
time to time to enable such holder or beneficial holder to sell its Debentures
or Common Stock without registration under the Securities Act within the
limitation of the exemption provided by Rule 144A, as such Rule may be amended
from time to time. Upon the request of any holder or any beneficial holder of
the Debentures or such Common Stock, the Company will deliver to such holder a
written statement as to whether it has complied with such requirements.

      Section 6.07. Stay, Extension and Usury Laws. The Company covenants (to
the extent that it may lawfully do so) that it shall not at any time insist
upon, plead, or in any manner whatsoever claim or take the benefit or advantage
of, any stay, extension or usury law or other law that would prohibit or forgive
the Company from paying all or any portion of the principal of, Interest on, or
Additional Amounts, if any, on, the Debentures as contemplated herein, wherever

                                       52
<PAGE>

enacted, now or at any time hereafter in force, or that may affect the covenants
or the performance of this Indenture and the Company (to the extent it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not, by resort to any such law, 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.

      Section 6.08. Compliance Certificate. The Company shall deliver to the
Trustee, within one hundred twenty (120) days after the end of each fiscal year
of the Company (beginning with the fiscal year ended September 30, 2005), a
certificate signed by either the principal executive officer, president,
principal financial officer or principal accounting officer of the Company,
stating whether or not to the knowledge of the signer thereof the Company is in
default in the performance and observance of any of the terms, provisions and
conditions of this Indenture (without regard to any period of grace or
requirement of notice provided hereunder) and, if the Company shall be in
default, specifying all such defaults and the nature and the status thereof of
which the signer may have knowledge.

      The Company will deliver to the Trustee, forthwith upon becoming aware of
(i) any default in the performance or observance of any covenant, agreement or
condition contained in this Indenture, or (ii) any Event of Default, an

required to pay Additional Amounts to holders of Debentures pursuant to the
Registration Rights Agreement, the Company will provide written notice of such
obligation (the "ADDITIONAL AMOUNTS NOTICE") to the Trustee within fifteen (15)
days of such obligation arising, and the Additional Amounts Notice shall set
forth the amount of such Additional Amounts to be paid by the Company. The
Trustee shall not at any time be under any duty or responsibility to any holder
of Debentures to determine the Additional Amounts, or with respect to the
nature, extent or calculation of the amount of Additional Amounts when made, or
with respect to the method employed in such calculation of the Additional
Amounts.

      Section 6.10. Additional Subsidiary Guarantees. If, during the Guarantee
Period, the Company or any of its Restricted Subsidiaries acquires or creates
another Subsidiary after the date of this Indenture that guarantees the Senior
Subordinated Notes due 2013 or any other Senior Subordinated Indebtedness or
Subordinated Indebtedness, then that newly acquired or created Subsidiary shall
become a Subsidiary Guarantor and execute a supplemental indenture and deliver
an Officer's Certificate and an Opinion of Counsel satisfactory to the Trustee

                                       53
<PAGE>

within 10 Business Days of the date on which it was acquired or created that
such supplemental indenture has been duly authorized, executed and delivered by
such Restricted Subsidiary and constitutes a valid, binding and enforceable
obligation of such Restricted Subsidiary; provided, however, that this Section
6.10 shall not apply to Subsidiaries that have properly been designated as
Unrestricted Subsidiaries in accordance with this Indenture for so long as they
continue to constitute Unrestricted Subsidiaries.

      Section 6.11. Designation of Restricted and Unrestricted Subsidiaries.
The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if that designation would not cause a Default and if the
Restricted Subsidiary meets the definition of an Unrestricted Subsidiary. The
Board of Directors may redesignate any Unrestricted Subsidiary to be a
Restricted Subsidiary if the redesignation would not cause a Default, provided,
however, that upon any such redesignation during the Guarantee Period, such
newly redesignated Restricted Subsidiary shall become a Subsidiary Guarantor and
execute a supplemental indenture and deliver an Officer's Certificate and an
Opinion of Counsel satisfactory to the Trustee within 10 Business Days of the
date on which it was so redesignated that such supplemental indenture has been
duly authorized, executed and delivered by such Restricted Subsidiary and
constitutes a valid, binding and enforceable obligation of such Restricted
Subsidiary.

      Section 6.12. Assumption of Obligations under Registration Rights
Agreement. Each Subsidiary of the Company who shall become a Subsidiary
Guarantor under the Indenture after the date hereof in accordance with Sections
5.04, 6.10 or 6.11 hereof shall be deemed to assume the obligations of a
Guarantor (as defined therein) under the Registration Rights Agreement, as if
such Subsidiary Guarantor had been an original signatory to such Registration
Rights Agreement.

to enable it to timely provide any notice to be provided by it hereunder), a
list in such form as the Trustee may reasonably require of the names and
addresses of the holders of Debentures as of a date not more than fifteen (15)
days (or such other date as the Trustee may reasonably request in order to so

except that no such list

                                       54
<PAGE>

need be furnished by the Company to the Trustee so long as the Trustee is acting
as the sole Debenture Registrar.

      Section 7.02. Preservation And Disclosure Of Lists. (a) The Trustee shall
preserve, in as current a form as is reasonably practicable, all information as
to the names and addresses of the holders of Debentures contained in the most

provided in Section 7.01 upon receipt of a new list so furnished.

      (a) The rights of Debentureholders to communicate with other holders of
Debentures with respect to their rights under this Indenture or under the
Debentures, and the corresponding rights and duties of the Trustee, shall be as
provided by the Trust Indenture Act.

      (b) Every Debentureholder, by receiving and holding the same, agrees with
the Company and the Trustee that neither the Company nor the Trustee nor any

information as to names and addresses of holders of Debentures made pursuant to
the Trust Indenture Act.

      Section 7.03. Reports By Trustee. (a) Within sixty (60) days after

<PAGE>

fifteen (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 an Officers' Certificates).

                                    ARTICLE 8

days

                                       56
<PAGE>

after written notice of such failure, requiring the Company to remedy the same,
shall have been given to the Company by the Trustee, or to the Company and the
Trustee by the holders of at least 25% in aggregate principal amount of the
Debentures at the time Outstanding determined in accordance with Section 10.04;
or

      (h) any final judgments or decree for the payment of money aggregating in
excess of $20,000,000 is entered against the Company, or any Subsidiary of the
Company and such judgment or decree is not paid, discharged or stayed for a
period of sixty (60) days after such final judgment or decree is required to be

      (i) default in the performance by the Company or any Subsidiary Guarantor

dealt with) continued for a period of sixty (60) days after the date on which
written notice of such failure, requiring the Company to remedy the same, shall
have been given to the Company by the Trustee, or the Company and the Trustee by
the holders of at least twenty-five percent (25%) in aggregate principal amount
of the Debentures at the time Outstanding determined in accordance with Section

      (j) (1) a Subsidiary Guarantee of a Subsidiary that is a "significant
subsidiary" as defined in Rule 1-02(w) of Regulation S-X ("SIGNIFICANT
SUBSIDIARY") ceases to be in full force and effect (other than in accordance
with the terms of the Indenture) or is declared to be null and void and
unenforceable, (2) the Subsidiary Guarantee of a Significant Subsidiary is found
to be invalid, or (3) a Subsidiary Guarantor that is a Significant Subsidiary
denies its liability under its Subsidiary Guarantee (other than by reason of
release of the Subsidiary Guarantor in accordance with the terms of the
Indenture); provided, however, that an Event of Default will also be deemed to
occur with respect to Subsidiary Guarantors that are not Significant
Subsidiaries ("INSIGNIFICANT SUBSIDIARIES") if (A) the Subsidiary Guarantees of
such Insignificant Subsidiaries cease to be in full force and effect (other than
in accordance with the terms of the Indenture) or are declared to be null and
void and unenforceable, (B) the Subsidiary Guarantees of such Insignificant
Subsidiaries are found to be invalid, or (C) such Insignificant Subsidiaries
deny their liability under their Subsidiary Guarantees (other than by reason of
release of the Subsidiary Guarantors in accordance with the terms of the
Indenture), if, when aggregated and taken as a whole, those Insignificant
Subsidiaries providing Subsidiary Guarantees on the Debentures would meet the
definition of a Significant Subsidiary;

      (k) the Company or any of its Restricted Subsidiaries that is a
Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a
whole, would constitute a Significant Subsidiary shall commence a voluntary case
or other proceeding seeking liquidation, reorganization or other relief with
respect

                                       57
<PAGE>

to such entity or its debts under any bankruptcy, insolvency or other similar
law now or hereafter in effect or seeking the appointment of a trustee,
receiver, liquidator, custodian or other similar official of any such entity or
any substantial part of the property of any such entity, or shall consent to any
such relief or to the appointment of or taking possession by any such official
in an involuntary case or other proceeding commenced against any such entity, or
shall make a general assignment for the benefit of creditors, or shall be unable
to pay its debts as they become due; or

      (l) an involuntary case or other proceeding shall be commenced against the
Company or any of its Restricted Subsidiaries that is a Significant Subsidiary
or any group of Restricted Subsidiaries that, taken as a whole, would constitute
a Significant Subsidiary seeking liquidation, reorganization or other relief
with respect to any such entity or its debts under any bankruptcy, insolvency or
other similar law now or hereafter in effect or seeking the appointment of a
trustee, receiver, liquidator, custodian or other similar official of any such
entity or any substantial part of the property of any such entity, and such
involuntary case or other proceeding shall remain undismissed and unstayed for a
period of sixty (60) consecutive days;

then, and in each and every such case (other than an Event of Default specified
in Section 8.01(k) or Section 8.01(l)), unless the principal of all of the
Debentures shall have already become due and payable, either the Trustee or the
holders of not less than twenty-five percent (25%) in aggregate principal amount
of the Debentures then Outstanding hereunder determined in accordance with
Section 10.04, by notice in writing to the Company (and to the Trustee if given
by Debentureholders), may declare the principal of all the Debentures and the
Interest and Additional Amounts, if any, accrued and unpaid thereon to be due
and payable immediately, and upon any such declaration the same shall become and
shall be immediately due and payable, anything in this Indenture or in the
Debentures contained to the contrary notwithstanding. If an Event of Default
specified in Section 8.01(k) or 8.01(l) occurs, the principal of all the
Debentures and the Interest and Additional Amounts, if any, accrued and unpaid
thereon shall be immediately and automatically due and payable without necessity
of further action. This provision, however, is subject to the conditions that
if, at any time after the principal of the Debentures shall have been so
declared due and payable, and before any judgment or decree for the payment of
the monies due shall have been obtained or entered as hereinafter provided, the
Company shall pay or shall deposit with the Trustee a sum sufficient to pay all
matured installments of Interest and Additional Amounts, if any, upon all
Debentures and the principal of any and all Debentures that shall have become
due otherwise than by acceleration (with interest on overdue installments of
Interest and Additional Amounts, if any, (to the extent that payment of such
interest is enforceable under applicable law) and on such principal at the rate
borne by the Debentures, to the date of such payment or deposit) and amounts due
to the Trustee pursuant to Section 9.06, and if any and all defaults under this
Indenture, other than the nonpayment of principal of and accrued and unpaid
Interest and Additional Amounts, if any, on

                                       58
<PAGE>

Debentures that shall have become due by acceleration, shall have been cured or
waived pursuant to Section 8.07, then and in every such case the holders of a
majority in aggregate principal amount of the Debentures then Outstanding, by
written notice to the Company and to the Trustee, may waive all defaults or
Events of Default and rescind and annul such declaration and its consequences;
but no such waiver or rescission and annulment shall extend to or shall affect
any subsequent default or Event of Default. The Company shall notify in writing
a Responsible Officer of the Trustee, promptly upon becoming aware thereof, of
any Event of Default.

      In case the Trustee shall have proceeded to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned because
of such waiver or rescission and annulment or for any other reason or shall have
been determined adversely to the Trustee, then and in every such case the
Company, the holders of Debentures, and the Trustee shall be restored
respectively to their several positions and rights hereunder, and all rights,
remedies and powers of the Company, the holders of Debentures, and the Trustee
shall continue as though no such proceeding had been taken.

      Section 8.02. Payments of Debentures on Default; Suit Therefor. The
Company covenants that (a) in case default shall be made in the payment of any
installment of Interest or Additional Amounts upon any of the Debentures as and
when the same shall become due and payable, and such default shall have
continued for a period of thirty (30) days, or (b) in case default shall be made
in the payment of the principal of any of the Debentures as and when the same
shall have become due and payable, whether at maturity of the Debentures or in
connection with any redemption or repurchase, by acceleration or otherwise,
then, upon demand of the Trustee, the Company will pay to the Trustee, for the
benefit of the holders of the Debentures, the whole amount that then shall have
become due and payable on all such Debentures for principal, Interest and
Additional Amounts, if any, as the case may be, with interest upon the overdue
principal and (to the extent that payment of such interest is enforceable under
applicable law) upon the overdue installments of Interest and Additional
Amounts, if any, at the rate borne by the Debentures and, in addition thereto,
such further amount as shall be sufficient to cover the costs and expenses of
collection, including reasonable compensation to the Trustee, its agents,
attorneys and counsel, and all other amounts due the Trustee under Section 9.06.
Until such demand by the Trustee, the Company may pay the principal of and
Interest and Additional Amounts, if any, on the Debentures to the registered
holders, whether or not the Debentures are overdue.

      In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered, at the written direction of the holders of a majority
in aggregate principal amount of the Debentures then outstanding, to institute
any actions or proceedings at law or in equity for the collection of the sums so
due and unpaid, and may prosecute any such action or proceeding to judgment or
final

                                       59
<PAGE>

decree, and may enforce any such judgment or final decree against the Company or
any other obligor on the Debentures and collect in the manner provided by law
out of the property of the Company or any other obligor on the Debentures
wherever situated the monies adjudged or decreed to be payable.

      In case there shall be pending proceedings for the bankruptcy or for the
reorganization of the Company, any Subsidiary Guarantor or any other obligor on
the Debentures under Title 11 of the United States Code, or any other applicable
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Company, such Subsidiary Guarantor or such other
obligor, the property of the Company, such Subsidiary Guarantor or such other
obligor, or in the case of any other judicial proceedings relative to the
Company, such Subsidiary Guarantor or such other obligor upon the Debentures, or
to the creditors or property of the Company, such Subsidiary Guarantor or such
other obligor, the Trustee, irrespective of whether the principal of the
Debentures shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand
pursuant to the provisions of this Section 8.02, shall be entitled and
empowered, by intervention in such proceedings or otherwise, to file and prove a
claim or claims for the whole amount of principal, Interest and Additional
Amounts, if any, owing and unpaid in respect of the Debentures, and, in case of
any judicial proceedings, to file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee and of the Debentureholders allowed in such judicial proceedings
relative to the Company, any Subsidiary Guarantor or any other obligor on the
Debentures, its or their creditors, or its or their property, and to collect and
receive any monies or other property payable or deliverable on any such claims,
and to distribute the same after the deduction of any amounts due the Trustee
under Section 9.06, and to take any other action with respect to such claims,
including participating as a member of any official committee of creditors, as
it reasonably deems necessary or advisable, and, unless prohibited by law or
applicable regulations, and any receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, custodian or similar official is hereby authorized
by each of the Debentureholders 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 Debentureholders, to pay to the Trustee any amount due it for reasonable
compensation, expenses, advances and disbursements, including reasonable counsel
fees and expenses incurred by it up to the date of such distribution. To the
extent that such payment of reasonable compensation, expenses, advances and
disbursements out of the estate in any such proceedings shall be denied for any
reason, payment of the same shall be secured by a lien on, and shall be paid out
of, any and all distributions, dividends, monies, securities and other property
that the holders of the Debentures may be entitled to receive in such
proceedings, whether in liquidation or under any plan of reorganization or
arrangement or otherwise.

                                       60
<PAGE>

      All rights of action and of asserting claims under this Indenture, or
under any of the Debentures, may be enforced by the Trustee without the
possession of any of the Debentures, or the production thereof at any trial or
other proceeding relative thereto, and any such suit or 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
Debentures.

      In any proceedings brought by the Trustee (and in any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the holders
of the Debentures, and it shall not be necessary to make any holders of the
Debentures parties to any such proceedings.

      Section 8.03. Application of Monies Collected By Trustee. Any monies
collected by the Trustee pursuant to this Article 8 shall be applied in the
order following, at the date or dates fixed by the Trustee for the distribution

fully paid:

Amounts, if any, with interest (to the extent that such interest has been
collected by the Trustee) upon the overdue installments of Interest and
Additional Amounts, if any, at the rate borne by the Debentures, such payments
to be made ratably to the Persons entitled thereto;

      THIRD: Subject to the provisions of Article 4, in case the principal of
the Outstanding Debentures shall have become due, by declaration or otherwise,
and be unpaid to the payment of the whole amount then owing and unpaid upon the
Debentures for principal, Interest and Additional Amounts, if any, with interest
on the overdue principal and (to the extent that such interest has been
collected by the Trustee) upon overdue installments of Interest and Additional
Amounts, if any, at the rate borne by the Debentures, and in case such monies
shall be insufficient to pay in full the whole amounts so due and unpaid upon
the Debentures, then to the payment of such principal, Interest and Additional
Amounts, if any, without preference or priority of principal over Interest or
Additional Amounts, if any, or of Interest over principal or Additional Amounts,
if any, or Additional Amounts, if any, over principal or Interest, or of any
installment of Interest over any other installment of Interest, or of any
installment of Additional Amounts over any other installment of Additional
Amounts, or of

                                       61

principal and accrued and unpaid Interest and Additional Amounts, if any; and

      FOURTH: Subject to the provisions of Article 4, to the payment of the
remainder, if any, to the Company or as a court shall direct in writing.

      Section 8.04. Proceedings by Debentureholder. No holder of any Debenture
shall have any right by virtue of or by reference to any provision of this
Indenture to institute any suit, action or proceeding in equity or at law upon
or under or with respect to this Indenture, or for the appointment of a
receiver, trustee, liquidator, custodian or other similar official, or for any
other remedy hereunder, unless (i) such holder previously shall have given to
the Trustee written notice of an Event of Default and of the continuance
thereof, as hereinbefore provided, (ii) holders of not less than twenty-five
percent (25%) in aggregate principal amount of the Debentures then Outstanding
shall have made written request upon the Trustee to institute such action, suit
or proceeding in its own name as Trustee hereunder and shall have offered to the
Trustee such reasonable security or indemnity as it may require against the
costs, expenses and liabilities to be incurred therein or thereby, (iii) no
direction inconsistent with such written request shall have been given to the
Trustee pursuant to Section 8.07 during the sixty (60) day period after its
receipt of such notice, request and offer of indemnity, and (iv) the Trustee for
such sixty (60) day period shall have failed to institute any such action, suit
or proceeding; it being understood and intended, and being expressly covenanted
by the taker and holder of every Debenture with every other taker and holder and
the Trustee, that no one or more holders of Debentures shall have any right in
any manner whatever by virtue of or by reference to any provision of this
Indenture to affect, disturb or prejudice the rights of any other holder of
Debentures, or to obtain or seek to obtain priority over or preference to any
other such holder, or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
holders of Debentures (except as otherwise provided herein). For the protection
and enforcement of this Section 8.04, each and every Debentureholder and the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

      Notwithstanding any other provision of this Indenture and any provision of
any Debenture, the right of any holder of any Debenture to receive payment of
the principal of (including the redemption price or repurchase price upon
redemption or repurchase pursuant to Article 3), and accrued and unpaid Interest
and Additional Amounts, if any, on such Debenture, on or after the respective
due dates expressed in such Debenture or in the event of redemption or
repurchase, or to institute suit for the enforcement of any such payment on or
after such respective dates against the Company shall be unconditional and shall
not be impaired or affected without the consent of such holder.

      Anything in this Indenture or the Debentures to the contrary
notwithstanding, the holder of any Debenture, without the consent of either the

                                       62
<PAGE>

Trustee or the holder of any other Debenture, on its own behalf and for its own
benefit, may enforce, and may institute and maintain any proceeding suitable to
enforce, its rights of conversion as provided herein.

      Section 8.05. Proceedings By Trustee. In case of an Event of Default, the
Trustee may, in its discretion, proceed to protect and enforce the rights vested
in it by this Indenture by such appropriate judicial proceedings as are
necessary to protect and enforce any of such rights, either by suit in equity or
by action at law or by proceeding in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or
in aid of the exercise of any power granted in this Indenture, or to enforce any
other legal or equitable right vested in the Trustee by this Indenture or by
law.

      Section 8.06. Remedies Cumulative And Continuing. Except as provided in
Section 2.06, all powers and remedies given by this Article 8 to the Trustee or
to the Debentureholders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any thereof or of any other powers and remedies
available to the Trustee or the holders of the Debentures, by judicial
proceedings or otherwise, to enforce the performance or observance of the
covenants and agreements contained in this Indenture, and no delay or omission
of the Trustee or of any holder of any of the Debentures to exercise any right
or power accruing upon any default or Event of Default occurring and continuing
as aforesaid shall impair any such right or power, or shall be construed to be a
waiver of any such default or any acquiescence therein, and, subject to the
provisions of Section 8.04, every power and remedy given by this Article 8 or by
law to the Trustee or to the Debentureholders may be exercised from time to
time, and as often as shall be deemed expedient, by the Trustee or by the
Debentureholders.

      Section 8.07. Direction of Proceedings and Waiver of Defaults By Majority
of Debentureholders. The holders of a majority in aggregate principal amount of
the Debentures at the time Outstanding determined in accordance with Section
10.04 shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust
or power conferred on the Trustee; provided that (a) such direction shall not be
in conflict with any rule of law or with this Indenture, (b) the Trustee may
take any other action that is not inconsistent with such direction, (c) the
Trustee may decline to take any action that would benefit some Debentureholder
to the detriment of other Debentureholders and (d) the Trustee may decline to
take any action that would involve the Trustee in personal liability. The
holders of a majority in aggregate principal amount of the Debentures at the
time Outstanding determined in accordance with Section 10.04 may, on behalf of
the holders of all of the Debentures, waive any past default or Event of Default
hereunder and its consequences except (u) a default in the payment of Interest
on, Additional Amounts, if any, on, or the principal of, the Debentures, (v) a
failure by the Company to convert any Debentures pursuant to Article 17, (w) a
default in the payment of the redemption price pursuant to Article 3, (x) a
default in the payment of the repurchase price pursuant to Article 3, (y) a
default in the delivery

                                       63
<PAGE>

of the Additional Shares, if any, when due; or (z) a default in respect of a
covenant or provisions hereof that under Article 12 cannot be modified or
amended without the consent of the holders of each or all Debentures then
Outstanding or affected thereby. Upon any such waiver, the Company, the Trustee
and the holders of the Debentures shall be restored to their former positions
and rights hereunder; but no such waiver shall extend to any subsequent or other
default or Event of Default. Whenever any default or Event of Default hereunder
shall have been waived as permitted by this Section 8.07, said default or Event
of Default shall for all purposes of the Debentures and this Indenture be deemed
to have been cured and to be not continuing; but no such waiver shall extend to
any subsequent or other default or Event of Default.

      Section 8.08. Notice of Defaults. The Trustee shall, within ninety (90)
days after a Responsible Officer of the Trustee has knowledge of the occurrence
of a default, mail to all Debentureholders, as the names and addresses of such
holders appear upon the Debenture Register, notice of all defaults known to a
Responsible Officer, unless such defaults shall have been cured or waived before
the giving of such notice; provided that except in the case of default in the
payment of the principal of, Interest on, Additional amounts, if any, on, or the
delivery of Additional Shares, if any, with respect to, the Debentures, the
Trustee shall be protected in withholding such notice if and so long as a trust
committee of directors and/or Responsible Officers of the Trustee in good faith
determines that the withholding of such notice is in the interests of the
Debentureholders.

      Section 8.09. Undertaking To Pay Costs. All parties to this Indenture
agree, and each holder of any Debenture by his acceptance thereof shall be
deemed to have agreed, that any court may, in its discretion, require, in any
suit for the enforcement of any right or remedy under this Indenture, or in any
suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of
such suit and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees and expenses, against any party litigant in
such suit, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; provided that the provisions of this
Section 8.09 (to the extent permitted by law) shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Debentureholder, or
group of Debentureholders, holding in the aggregate more than ten percent (10%)
in principal amount of the Debentures at the time Outstanding determined in
accordance with Section 10.04, or to any suit instituted by any Debentureholder
for the enforcement of the payment of the principal of, Interest on, or
Additional Amounts, if any, on any Debenture on or after the due date expressed
in such Debenture or to any suit for the enforcement of the right to convert any
Debenture in accordance with the provisions of Article 17.

                                   THE TRUSTEE

      Section 9.01. Duties and Responsibilities of Trustee. The Trustee, prior
to the occurrence of an Event of Default and after the curing of all Events of
Default that may have occurred, undertakes to perform such duties and only such
duties as are specifically set forth in this Indenture. In case an Event of
Default has occurred (which has not been cured or waived), 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.

      No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own willful misconduct, except that:

      (a) prior to the occurrence of an Event of Default and after the curing or
waiving of all Events of Default that may have occurred:

            (i) the duties and obligations of the Trustee shall be determined
      solely by the express provisions of this Indenture and the Trust Indenture
      Act, and the Trustee shall not be liable except for the performance of
      such duties and obligations as are specifically set forth in this
      Indenture and no implied covenants or obligations shall be read into this
      Indenture and the Trust Indenture Act against the Trustee; and

            (ii) in the absence of bad faith, gross negligence or willful
      misconduct on the part of the Trustee, the Trustee may conclusively rely
      as to the truth of the statements and the correctness of the opinions
      expressed therein, upon any certificates or opinions furnished to the
      Trustee and conforming to the requirements of this Indenture; but, in the
      case of any such certificates or opinions that by any provisions 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
      conform to the requirements of this Indenture (but need not confirm or
      investigate the accuracy of any mathematical calculations or other facts
      stated therein);

      (b) the Trustee shall not be liable for any error of judgment made in good
faith by a Responsible Officer or Officers of the Trustee, unless the Trustee
was negligent in ascertaining the pertinent facts;

      (c) the Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith in accordance with the written direction
of the holders of not less than a majority in principal amount of the Debentures
at the time Outstanding determined as provided in Section 10.04 relating to the
time, method and place of conducting any proceeding for any remedy available to
the

                                       65
<PAGE>

Trustee, or exercising any trust or power conferred upon the Trustee, under this
Indenture;

      (d) whether or not therein provided, every provision of this Indenture
relating to the conduct or affecting the liability of, or affording protection
to, the Trustee shall be subject to the provisions of this Section;

      (e) the Trustee shall not be liable in respect of any payment (as to the
correctness of amount, entitlement to receive or any other matters relating to
payment) or notice effected by the Company or any paying agent or any records
maintained by any co-registrar with respect to the Debentures;

      (f) if any party fails to deliver a notice relating to an event the fact
of which, pursuant to this Indenture, requires notice to be sent to the Trustee,
the Trustee may conclusively rely on its failure to receive such notice as
reason to act as if no such event occurred; and

      (g) the Trustee shall not be deemed to have knowledge of any default or
Event of Default hereunder unless it shall have been notified in writing of such
default or Event of Default by the Company or the holders of at least 10% in
aggregate principal amount of the Debentures.

      None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there is reasonable ground for believing that the
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

      Section 9.02. Reliance on Documents, Opinions, Etc. Except as otherwise
provided in Section 9.01:

      (a) the Trustee may conclusively rely and shall be protected in acting
upon any resolution, certificate, statement, instrument, opinion, report,
notice, request, consent, order, bond, debenture, note, coupon or other paper or
document (whether in its original or facsimile form) believed by it in good
faith to be genuine and to have been signed or presented by the proper party or
parties;

      (b) any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof be herein specifically prescribed); and any
resolution of the Board of Directors of the Company may be evidenced to the
Trustee by a copy thereof certified by the Secretary or an Assistant Secretary
of the Company;

      (c) the Trustee may consult with counsel of its own selection and any
advice or Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken or omitted by it hereunder in good
faith and in accordance with such advice or Opinion of Counsel;

                                       66
<PAGE>

      (d) 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 Debentureholders pursuant to the provisions of this Indenture, unless
such Debentureholders shall have offered to the Trustee reasonable security or
indemnity satisfactory to it against the costs, expenses and liabilities that
may be incurred therein or thereby;

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

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

      (g) the Trustee shall not be liable for any action taken, suffered or
omitted to be taken by it in good faith and reasonably believed by it to be
authorized or within the discretion or rights or powers conferred upon it by
this Indenture;

      (h) 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;

      (i) the Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture,
which Officers' Certificate may be signed by any person authorized to sign an
Officers' Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded; and

      (j) any permissive right or authority granted to the Trustee shall not be
construed as a mandatory duty.

      Section 9.03 . No Responsibility For Recitals, Etc. The recitals contained
herein and in the Debentures (except in the Trustee's certificate of
authentication) shall be taken as the statements of the Company, and the Trustee
assumes no responsibility for the correctness of the same. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the

                                       67
<PAGE>

Debentures. The Trustee shall not be accountable for the use or application by
the Company of any Debentures or the proceeds of any Debentures authenticated
and delivered by the Trustee in conformity with the provisions of this
Indenture.

      Section 9.04. Trustee, Paying Agents, Conversion Agents or Registrar May
Own Debentures. The Trustee, any paying agent, any conversion agent or Debenture
Registrar, in its individual or any other capacity, may become the owner or
pledgee of Debentures with the same rights it would have if it were not Trustee,
paying agent, conversion agent or Debenture Registrar.

      Section 9.05. Monies to Be Held in Trust. All monies received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as may be agreed in writing from time to time by
the Company and the Trustee.

      Section 9.06. Compensation and Expenses of Trustee. The Company covenants
and agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, such compensation for all services rendered by it hereunder in any
capacity (which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust) as mutually agreed to from time
to time in writing between the Company and the Trustee, and the Company will pay
or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances reasonably incurred or made by the Trustee in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all Persons not regularly in its employ) except any such expense, disbursement
or advance as may be attributable to its own negligence, willful misconduct,
recklessness or bad faith. The Company also covenants to indemnify the Trustee
and any predecessor Trustee (or any officer, director or employee of the
Trustee), in any capacity under this Indenture and its agents and any
authenticating agent for, and to hold them harmless against, any and all loss,
liability, damage, claim or expense including taxes (other than franchise taxes
and taxes based on the income of the Trustee) incurred without negligence,
willful misconduct, recklessness or bad faith on the part of the Trustee or such
officers, directors, employees and agent or authenticating agent, as the case
may be, and arising out of or in connection with the acceptance or
administration of this trust or in any other capacity hereunder, including the
costs and expenses of defending themselves against any claim (whether asserted
by the Company, any holder or any other Person) of liability in connection with
the exercise or performance of any of its or their powers or duties hereunder.
If the Company fails to compensate or indemnify the Trustee and to pay or
reimburse the Trustee for expenses, disbursements and advances under this
Section 9.06, the Trustee's claim shall be secured by a lien prior to that of
the Debentures upon all property and funds held or collected by the Trustee as
such, except funds held in trust for the benefit of the

                                       68
<PAGE>

holders of particular Debentures. The obligation of the Company under this
Section shall survive the satisfaction and discharge of this Indenture and the
resignation or removal of the Trustee.

      When the Trustee and its agents and any authenticating agent incur
expenses or render services after an Event of Default specified in Section
8.01(k) or Section 8.01(l) with respect to the Company occurs, the expenses and
the compensation for the services are intended to constitute expenses of
administration under any bankruptcy, insolvency or similar laws.

      Section 9.07. Officers' Certificate As Evidence. Except as otherwise
provided in Section 9.01, whenever in the administration of the provisions of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or omitting any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of bad faith or willful misconduct on the part
of the Trustee, be deemed to be conclusively proved and established by an
Officers' Certificate delivered to the Trustee.

      Section 9.08. Conflicting Interests of Trustee. If the Trustee has or
shall acquire a conflicting interest within the meaning of the Trust Indenture
Act, the Trustee shall either eliminate such interest or resign, to the extent
and in the manner provided by, and subject to the provisions of, the Trust
Indenture Act and this Indenture.

      Section 9.09. Eligibility of Trustee. There shall at all times be a
Trustee hereunder that shall be a Person that is eligible pursuant to the Trust
Indenture Act to act as such and has a combined capital and surplus of at least
$50,000,000 (or if such Person is a member of a bank holding company system, its
bank holding company shall have a combined capital and surplus of at least
$50,000,000). If such Person publishes reports of condition at least annually,
pursuant to law or to the requirements of any supervising or examining
authority, then for the purposes of this Section the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time
the Trustee shall cease to be eligible in accordance with the provisions of this
Section 9.09, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

      Section 9.10. Resignation or Removal of Trustee.

      (a) The Trustee may at any time resign by giving written notice of such
resignation to the Company and to the holders of Debentures. Upon receiving such
notice of resignation, the Company shall promptly appoint a successor trustee by
written instrument, in duplicate, executed by order of the Board of Directors of
the Company, one copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor trustee. If no successor trustee shall
have been so appointed and have accepted appointment sixty (60) days after

                                       69
<PAGE>

the mailing of such notice of resignation to the Debentureholders, the resigning
Trustee may, upon ten (10) Business Days' notice to the Company and the
Debentureholders, appoint a successor identified in such notice or may petition,
at the expense of the Company, any court of competent jurisdiction for the
appointment of a successor trustee, or, if any Debentureholder who has been a
bona fide holder of a Debenture or Debentures for at least six (6) months may,
subject to the provisions of Section 8.09, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor
trustee. Such court may thereupon, after such notice, if any, as it may deem
proper and prescribe, appoint a successor trustee.

      (b) In case at any time any of the following shall occur:

            (i) the Trustee shall fail to comply with Section 9.08 after written
      request therefor by the Company or by any Debentureholder who has been a
      bona fide holder of a Debenture or Debentures for at least six (6) months;
      or

            (ii) the Trustee shall cease to be eligible in accordance with the
      provisions of Section 9.09 and shall fail to resign after written request
      therefor by the Company or by any such Debentureholder; or

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

then, in any such case, the Company may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors of the Company, one copy of which instrument shall be
delivered to the Trustee so removed and one copy to the successor trustee, or,
subject to the provisions of Section 8.09, any Debentureholder who has been a
bona fide holder of a Debenture or Debentures for at least six (6) months may,
on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor trustee; provided that if no successor Trustee shall have been
appointed and have accepted appointment sixty (60) days after either the Company
or the Debentureholders has removed the Trustee, the Trustee so removed may
petition, at the expense of the Company, any court of competent jurisdiction for
an appointment of a successor trustee. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, remove the Trustee and
appoint a successor trustee.

      (c) The holders of a majority in aggregate principal amount of the
Debentures at the time Outstanding may at any time remove the Trustee and
nominate a successor trustee that shall be deemed appointed as successor trustee

                                       70
<PAGE>

unless, within ten (10) days after notice to the Company of such nomination, the
Company objects thereto, in which case the Trustee so removed or any
Debentureholder, or if such Trustee so removed or any Debentureholder fails to
act, the Company, upon the terms and conditions and otherwise as in Section
9.10(a) provided, may petition any court of competent jurisdiction for an
appointment of a successor trustee.

      (d) Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 9.10 shall
become effective only upon acceptance of appointment by the successor trustee as
provided in Section 9.11.

      (e) Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 9.06 shall continue for the
benefit of the retiring Trustee.

      Section 9.11. Acceptance by Successor Trustee. Any successor trustee
appointed as provided in Section 9.10 shall execute, acknowledge and deliver to
the Company and to its predecessor trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights,
powers, duties and obligations of its predecessor hereunder, with like effect as
if originally named as trustee herein; but, nevertheless, on the written request
of the Company or of the successor trustee, the trustee ceasing to act shall,
upon payment of any amount then due it pursuant to the provisions of Section
9.06, execute and deliver an instrument, provided to it and in a form
satisfactory to such trustee, transferring to such successor trustee all the
rights and powers of the trustee so ceasing to act. Upon request of any such
successor trustee, the Company shall execute any and all instruments in writing
for more fully and certainly vesting in and confirming to such successor trustee
all such rights and powers. Any trustee ceasing to act shall, nevertheless,
retain a lien upon all property and funds held or collected by such trustee as
such, except for funds held in trust for the benefit of holders of particular
Debentures, to secure any amounts then due it pursuant to the provisions of
Section 9.06.

      No successor trustee shall accept appointment as provided in this Section
9.11 unless, at the time of such acceptance, such successor trustee shall be
qualified under the provisions of Section 9.08 and be eligible under the
provisions of Section 9.09.

      Upon acceptance of appointment by a successor trustee as provided in this
Section 9.11, the Company (or the former trustee, at the written direction of
the Company) shall mail or cause to be mailed notice of the succession of such
trustee hereunder to the holders of Debentures at their addresses as they shall
appear on the Debenture Register. If the Company fails to mail such notice
within ten (10)

                                       71
<PAGE>

days after acceptance of appointment by the successor trustee, the successor
trustee shall cause such notice to be mailed at the expense of the Company.

      Section 9.12. Succession By Merger. Any corporation into which the
Trustee may be merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any corporation succeeding to all or substantially
all of the corporate trust business of the Trustee (including any trust created
by this Indenture), shall be the successor to the Trustee hereunder without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, provided that in the case of any corporation succeeding to all
or substantially all of the corporate trust business of the Trustee, such
corporation shall be qualified under the provisions of Section 9.08 and eligible
under the provisions of Section 9.09.

      In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture, any of the Debentures shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor trustee or authenticating agent
appointed by such predecessor trustee, and deliver such Debentures so
authenticated; and in case at that time any of the Debentures shall not have
been authenticated, any successor to the Trustee or any authenticating agent
appointed by such successor trustee may authenticate such Debentures in the name
of the successor trustee; and in all such cases such certificates shall have the
full force that is provided in the Debentures or in this Indenture; provided
that the right to adopt the certificate of authentication of any predecessor
Trustee or authenticate Debentures in the name of any predecessor Trustee shall
apply only to its successor or successors by merger, conversion or
consolidation.

      Section 9.13. Preferential Collection of Claims. If and when the Trustee
shall be or become a creditor of the Company (or any other obligor upon the
Debentures), the Trustee shall be subject to the provisions of the Trust
Indenture Act regarding the collection of the claims against the Company (or any
such other obligor).

      Section 9.14. Limitation Of Liability. It is understood by the parties
hereto other than the The Bank of New York (the "BANK") that the sole recourse
of the parties hereto other than the Bank in respect of the obligations of the
Trustee hereunder and under the other documents contemplated thereby and related
thereto to which it is a party shall be to the parties hereto and thereto other
than the Bank. In addition, the Bank is entering into this Indenture and the
other documents contemplated thereby and related thereto to which it is a party
solely in its capacity as Trustee under the Indenture and not in its individual
capacity (except as expressly stated herein) and in no case shall the Bank (or
any Person acting as successor trustee under the Indenture) be personally liable
for or on account of any of the statements, representations, warranties,
covenants or obligations stated to be those of the Company hereunder or
thereunder, all such

                                       72
<PAGE>

liability, if any, being expressly waived by the parties hereto and any person
claiming by, through or under such party, provided, however, that the Bank (or
any such successor trustee) shall be personally liable hereunder and thereunder
for its own negligence or willful misconduct or for its material breach of its
covenants, representations and warranties contained herein or therein, to the
extent expressly covenanted or made in its individual capacity. In no event
shall the Trustee, in its capacity as paying agent, Debenture Registrar or in
any other capacity hereunder, be liable under or in connection with this
Indenture for indirect, special, incidental, punitive or consequential losses or
damages of any kind whatsoever, including but not limited to lost profits,
whether or not foreseeable, even if the Trustee has been advised of the
possibility thereof and regardless of the form of action in which such damages
are sought. The provisions of this Section shall survive the termination of the
Indenture and the resignation or removal of the Trustee.

                              THE DEBENTUREHOLDERS

      Section 10.01. Action By Debentureholders. Whenever in this Indenture it
is provided that the holders of a specified percentage in aggregate principal
amount of the Debentures may take any action (including the making of any demand
or request, the giving of any notice, consent or waiver or the taking of any
other action), the fact that at the time of taking any such action, the holders
of such specified percentage have joined therein may be evidenced (a) by any
instrument or any number of instruments of similar tenor executed by
Debentureholders in person or by agent or proxy appointed in writing, or (b) by
the record of the holders of Debentures voting in favor thereof at any meeting
of Debentureholders duly called and held in accordance with the provisions of
Article 11, or (c) by a combination of such instrument or instruments and any
such record of such a meeting of Debentureholders. Whenever the Company or the
Trustee solicits the taking of any action by the holders of the Debentures, the
Company or the Trustee may fix in advance of such solicitation, a date as the
record date for determining holders entitled to take such action. The record
date shall be not more than fifteen (15) days prior to the date of commencement
of solicitation of such action.

      Section 10.02. Proof of Execution by Debentureholders. Subject to the
provisions of Sections 9.01, 9.02 and 11.05, proof of the execution of any
instrument by a Debentureholder or its agent or proxy shall be sufficient if
made in accordance with such reasonable rules and regulations as may be
prescribed by the Trustee or in such manner as shall be satisfactory to the
Trustee. The holding of Debentures shall be proved by the registry of such
Debentures or by a certificate of the Debenture Registrar.

      The record of any Debentureholders' meeting shall be proved in the manner
provided in Section 11.06.

                                       73
<PAGE>

      Section 10.03. Who Are Deemed Absolute Owners. The Company, the Trustee,
any paying agent, any conversion agent and any Debenture Registrar may deem the
Person in whose name such Debenture shall be registered upon the Debenture
Register to be, and may treat it as, the absolute owner of such Debenture
(whether or not such Debenture shall be overdue and notwithstanding any notation
of ownership or other writing thereon made by any Person other than the Company
or any Debenture Registrar) for the purpose of receiving payment of or on
account of the principal of, Interest on, and Additional Amounts, if any, on,
such Debenture, for conversion of such Debenture and for all other purposes; and
neither the Company nor the Trustee nor any authenticating agent nor any paying
agent nor any conversion agent nor any Debenture Registrar shall be affected by
any notice to the contrary. All such payments so made to any holder for the time
being, or upon his order, shall be valid, and, to the extent of the sum or sums
so paid, effectual to satisfy and discharge the liability for monies payable
upon any such Debenture.

      Section 10.04. Company-Owned Debentures Disregarded. In determining
whether the holders of the requisite aggregate principal amount of Debentures
have concurred in any direction, consent, waiver or other action under this
Indenture, Debentures that are owned by the Company or any other obligor on the
Debentures or any Affiliate of the Company or any other obligor on the
Debentures shall be disregarded and deemed not to be Outstanding for the purpose
of any such determination; provided that for the purposes of determining whether
the Trustee shall be protected in relying on any such direction, consent, waiver
or other action, only Debentures that a Responsible Officer knows are so owned
shall be so disregarded. Debentures so owned that have been pledged in good
faith may be regarded as Outstanding for the purposes of this Section 10.04 if
the pledgee shall establish to the satisfaction of the Trustee the pledgee's
right to vote such Debentures and that the pledgee is not the Company, any other
obligor on the Debentures or any Affiliate of the Company or any such other
obligor. In the case of a dispute as to such right, any decision by the Trustee
taken upon the advice of counsel shall be full protection to the Trustee. Upon
request of the Trustee, the Company shall furnish to the Trustee promptly an
Officers' Certificate listing and identifying all Debentures, if any, known by
the Company to be owned or held by or for the account of any of the above
described Persons, and, subject to Section 9.01, the Trustee shall be entitled
to accept such Officers' Certificate as conclusive evidence of the facts therein
set forth and of the fact that all Debentures not listed therein are Outstanding
for the purpose of any such determination.

      Section 10.05. Revocation Of Consents, Future Holders Bound. At any time
prior to (but not after) the evidencing to the Trustee, as provided in Section
10.01, of the taking of any action by the holders of the percentage in aggregate
principal amount of the Debentures specified in this Indenture in connection
with such action, any holder of a Debenture that is shown by the evidence to be
included in the Debentures the holders of which have consented to such action
may, by filing written notice with the Trustee at its Corporate Trust Office and

                                       74
<PAGE>

upon proof of holding as provided in Section 10.02, revoke such action so far as
concerns such Debenture. Except as aforesaid, any such action taken by the
holder of any Debenture shall be conclusive and binding upon such holder and
upon all future holders and owners of such Debenture and of any Debentures
issued in exchange or substitution therefor, irrespective of whether any
notation in regard thereto is made upon such Debenture or any Debenture issued
in exchange or substitution therefor.

                                       75
<PAGE>

of Debentureholders, by written request setting forth in reasonable detail the
action proposed to be taken at the meeting, and the Trustee shall not have
mailed the notice of such meeting within twenty (20) days after receipt of such
request, then the Company or such Debentureholders may determine the time and

of Debentures and of the appointment of proxies, and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall think fit.

      The Trustee shall, by an instrument in writing, appoint a temporary

Company or by Debentureholders as provided in Section 11.03, in which case the
Company or the Debentureholders calling the meeting, as the case may be, shall

      Subject to the provisions of Section 10.04, at any meeting each
Debentureholder or proxyholder shall be entitled to one vote for each $1,000
principal amount of Debentures held or represented by him; provided that no vote
shall be cast or counted at any meeting in respect of any Debenture challenged

permanent chairman and secretary of the meeting and one of the duplicates shall
be delivered to the Company and the other to the Trustee to be preserved by the
Trustee, the latter to have attached thereto the ballots voted at the meeting.

      Any record so signed and verified shall be conclusive evidence of the

Article 11 shall be deemed or construed to authorize or permit, by reason of any
call of a meeting of Debentureholders or any rights expressly or impliedly

Directors of the Company or any such Subsidiary Guarantor and the Trustee shall
consider to be for the benefit of the holders of Debentures, and to make the
occurrence, or the occurrence and continuance, of a default in any such
additional covenants, restrictions or conditions a default or an Event of
Default permitting the enforcement of all or any of the several remedies
provided in this Indenture as herein set forth; provided that in respect of any
such additional covenant, restriction or condition, such supplemental indenture
may provide for a particular period of grace after default (which period may be

provide for an immediate enforcement upon such default or may limit the remedies
available to the Trustee upon such default;

      (e) to provide for the issuance under this Indenture of Debentures in

purpose;

      (f) to cure any ambiguity or omission or to correct or supplement any
provision contained herein or in any supplemental indenture that may be

questions arising under this Indenture that shall not materially adversely
affect the interests of the holders of the Debentures;

      (g) to evidence and provide for the acceptance of appointment hereunder by

<PAGE>

      (h) to modify, eliminate or add to the provisions of this Indenture to
such extent as shall be necessary to comply with the requirements of the
Commission or to effect or maintain the qualifications of this Indenture under
the Trust Indenture Act, or under any similar federal statute hereafter enacted;

      (i) make other changes to the Indenture or forms or terms of the

of the Debentureholders;

      (j) conform any provision of the Indenture to the "Description of the
Debentures" section of the Offering Memorandum; or

      (k) to reflect the release of a Subsidiary Guarantor from its obligations
with respect to its Subsidiary Guarantee in accordance with the provisions of
Section 5.04 and to add a Subsidiary Guarantor pursuant to the requirements of
Sections 5.04 and 6.10.

      Upon the written request of the Company, accompanied by a copy of the
resolutions of the Board of Directors of the Company certified by its Secretary
or Assistant Secretary authorizing the execution of any supplemental indenture,
the Trustee is hereby authorized to join with the Company and any Subsidiary
Guarantor in the execution of any such supplemental indenture, to make any
further appropriate agreements and stipulations that may be therein contained
and to accept the conveyance, transfer and assignment of any property
thereunder, but the Trustee shall not be obligated to, but may in its
discretion, enter into any supplemental indenture that affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise.

      Any supplemental indenture authorized by the provisions of this Section
12.01 may be executed by the Company, any Subsidiary Guarantor and the Trustee
without the consent of the holders of any of the Debentures at the time
Outstanding, notwithstanding any of the provisions of Section 12.02.

      Notwithstanding any other provision of the Indenture or the Debentures,
the Registration Rights Agreement and the obligation to pay Additional Amounts
thereunder may be amended, modified or waived only in accordance with the
provisions of the Registration Rights Agreement.

      Section 12.02. Supplemental Indenture With Consent Of Debentureholders.
With the consent (evidenced as provided in Article 10) of the holders of at
least a majority in aggregate principal amount of the Debentures at the time
Outstanding, the Company and the Subsidiary Guarantors, when authorized by the
resolutions of their Board of Directors, and the Trustee may, from time to time
and at any time, enter into an indenture or indentures supplemental hereto for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or any

                                       79
<PAGE>

supplemental indenture or of modifying in any manner the rights of the holders
of the Debentures; provided that, without the consent of the holders of all
Debentures then Outstanding, no such supplemental indenture shall (a) extend the
fixed maturity of any Debenture, (b) reduce the rate or extend the time for
payment of Interest or Additional Amounts thereon, (c) reduce the principal
amount thereof, (d) reduce any amount payable upon redemption or repurchase
thereof, (e) change the obligation of the Company to redeem any Debenture on a

the obligation of the Company to repurchase any Debenture on a Repurchase Date
in a manner adverse to the holders of the Debentures, (g) reduce the amount of
the Additional Shares or otherwise impair the right of a holder to receive the
Additional Shares due on any Debenture, (h) change the obligation of the Company
to repurchase any Debenture upon the happening of a Designated Event in a manner
adverse to the holders of the Debentures, (i) impair the right of any Debenture
holder to institute suit for the payment thereof, (j) make the principal

Section 12.02 or Section 8.07, except to increase any such percentage or to
provide that certain other provisions of the Indenture cannot be modified or
waived without the consent of the holder of each Debenture so affected or (o)
reduce the aforesaid percentage of Debentures, the holders of which are required
to consent to any such supplemental indenture.

      Notwithstanding the foregoing, with the consent of the holders of at least
25% in aggregate principal amount of the Debentures at the time Outstanding, the
Company and the Subsidiary Guarantors, when authorized by the resolutions of the
Board of Directors, and the Trustee may, from time to time and at any time,
enter into an indenture or indentures supplemental hereto for the purpose of
modifying Section 17.02 such that, from and after the date of such modification
or amendment, the Company shall have the ability to satisfy the Principal Return
upon conversion of a Debenture in cash, Common Stock or any combination thereof;
provided, however, that the Company may, without the consent of the holders, (i)
increase the percentage of such holders required to approve the amendment or
modification set forth in this paragraph or (ii) eliminate the Company's right
to implement any such amendment or modification.

      In addition, the provisions of Article 4 may not be amended or modified in
a manner adverse to the holders of the Debentures without the consent of the
holders of at least 75% in aggregate principal amount of the Debentures
then-Outstanding. Notwithstanding the foregoing, no amendment or modification of
the Indenture may occur that amends or modifies, or otherwise adversely affects

                                       80
<PAGE>

the rights of the holders of Senior Indebtedness under Article 4, without the
prior written consent of the holders of such Senior Indebtedness or the agent
therefor acting on their behalf.

      Upon the written request of the Company, accompanied by a copy of the
resolutions of the Board of Directors of the Company certified by its Secretary
or Assistant Secretary authorizing the execution of any such supplemental
indenture, and upon the filing with the Trustee of evidence of the consent of
Debentureholders as aforesaid, the Trustee shall join with the Company and any
Subsidiary Guarantor in the execution of such supplemental indenture unless such
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise, in which case the Trustee may in its
discretion, but shall not be obligated to, enter into such supplemental
indenture.

      It shall not be necessary for the consent of the Debentureholders under
this Section 12.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

      Section 12.03. Effect Of Supplemental Indenture. Any supplemental
indenture executed pursuant to the provisions of this Article 12 shall comply
with the Trust Indenture Act, as then in effect, provided that this Section
12.03 shall not require such supplemental indenture or the Trustee to be
qualified under the Trust Indenture Act prior to the time such qualification is
in fact required under the terms of the Trust Indenture Act or the Indenture has
been qualified under the Trust Indenture Act, nor shall it constitute any
admission or acknowledgment by any party to such supplemental indenture that any
such qualification is required prior to the time such qualification is in fact
required under the terms of the Trust Indenture Act or the Indenture has been
qualified under the Trust Indenture Act. Upon the execution of any supplemental
indenture pursuant to the provisions of this Article 12, this Indenture shall be
and be deemed to be modified and amended in accordance therewith and the
respective rights, limitation of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Company, the Subsidiary Guarantors and
the holders of Debentures shall thereafter be determined, exercised and enforced
hereunder, subject in all respects to such modifications and amendments and all
the terms and conditions of any such supplemental indenture shall be and be
deemed to be part of the terms and conditions of this Indenture for any and all
purposes.

      Section 12.04. Notation On Debentures. Debentures authenticated and
delivered after the execution of any supplemental indenture pursuant to the
provisions of this Article 12 may bear a notation in form approved by the
Trustee as to any matter provided for in such supplemental indenture. If the
Company or the Trustee shall so determine, new Debentures so modified as to
conform, in the opinion of the Trustee and the Company's Board of Directors, to
any modification of this Indenture contained in any such supplemental indenture
may, at the Company's expense, be prepared and executed by the Company,
authenticated by

                                       81
<PAGE>

the Trustee (or an authenticating agent duly appointed by the Trustee pursuant
to Section 18.10) and delivered in exchange for the Debentures then Outstanding,
upon surrender of such Debentures then Outstanding.

      Section 12.05. Evidence Of Compliance Of Supplemental Indenture To Be
Furnished To Trustee. Prior to entering into any supplemental indenture, the
Trustee shall be provided with an Officers' Certificate and an Opinion of
Counsel providing or stating that any supplemental indenture executed pursuant
hereto complies with the requirements of this Article 12 and is otherwise
authorized or permitted by this Indenture and that all conditions precedent
thereto have been complied with.

surviving corporation) or (2) sell, assign, transfer, convey or otherwise
dispose of all or substantially all of the properties or assets of the Company
and its Restricted Subsidiaries, taken as a whole, in one or more related
transactions, to another Person; unless:

            (i) either (a) the Company is the surviving corporation, or (b) the
      Person formed by or surviving any such consolidation or merger (if other
      than the Company) or to which such sale, assignment, transfer, conveyance
      or other disposition has been made is a corporation organized or existing
      under the laws of the United States of America, any state thereof or the
      District of Columbia;

            (ii) the Person formed by or surviving any such consolidation or
      merger (if other than the Company) or the Person to which such sale,
      assignment, transfer, conveyance or other disposition has been made
      assumes all the obligations of the Company or of any such Restricted
      Subsidiary, as the case may be, under the Debentures and this Indenture by
      supplemental indenture satisfactory in form and substance to the Trustee;
      provided that this clause (ii) shall not apply to any person that becomes
      subject to the obligations of the Company under the Debentures and
      Indenture by operation of law; and

            (iii) immediately after giving effect to the transaction described
      above, no Event of Default, and no event that, after notice or lapse of
      time

                                       82
<PAGE>

      or both, would become an Event of Default, shall have happened and be
      continuing.

      The Company shall not, directly or indirectly, lease all or substantially
all of its properties or assets, in one or more related transactions, to any
other Person.

      Section 14.02. Successor To Be Substituted. Upon any such consolidation
or merger, or any sale, assignment, transfer, conveyance or other disposition of
all or substantially all the assets of the Company and its Restricted
Subsidiaries in a transaction that complies with Section 14.01 hereof, upon the
assumption by the successor Person, by supplemental indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the
obligations of Company or of any Restricted Subsidiary, as the case may be,
under the Debentures and this Indenture, such successor Person shall succeed to
and be substituted for the Company or such Restricted Subsidiary, with the same
effect as if it had been named herein as the party of this first part, and the
Company or such Restricted Subsidiary, as the case may be, shall be relieved of
all further obligations under the Debentures and this Indenture. Such successor
Person thereupon may cause to be signed, and may issue either in its own name or
in the name of the Company or the Restricted Subsidiary, as the case may be, any
or all of the Debentures or Subsidiary Guarantees, as the case may be, issuable
hereunder that theretofore shall not have been signed by the Company or such
Restricted Subsidiary and delivered to the Trustee; and, upon the order of such
successor Person instead of the Company or such Restricted Subsidiary and
subject to all the terms, conditions and limitations in this Indenture
prescribed, the Trustee shall authenticate and shall deliver, or cause to be
authenticated and delivered, any Debentures and Subsidiary Guarantees that
previously shall have been signed and delivered by the officers of the Company
or such Restricted Subsidiary to the Trustee for authentication, and any
Debentures and Subsidiary Guarantees that such successor Person thereafter shall
cause to be signed and delivered to the Trustee for that purpose. All the
Debentures and Subsidiary Guarantees so issued shall in all respects have the
same legal rank and benefit under this Indenture as the Debentures and
Subsidiary Guarantees theretofore or thereafter issued in accordance with the
terms of this Indenture as though all of such Debentures and Subsidiary
Guarantees had been issued at the date of the execution hereof. In the event of
any such consolidation, merger, sale, conveyance or transfer, the Person named
as the "COMPANY" in the first paragraph of this Indenture, or as Subsidiary
Guarantor on the signature page hereto, as the case may be, or any successor
that shall thereafter have become such in the manner prescribed in this Article
14 may be dissolved, wound up and liquidated at any time thereafter and such
Person shall be released from its liabilities as obligor and maker or Subsidiary
Guarantor, as the case may be, of the Debentures and from its obligations under
this Indenture.

      In case of any such consolidation or merger, or any sale, assignment,
transfer, conveyance or other disposition, such changes in phraseology and form

                                       83
<PAGE>

(but not in substance) may be made in the Debentures and Subsidiary Guarantees
thereafter to be issued as may be appropriate.

      Section 14.03. Opinion Of Counsel To Be Given Trustee. The Trustee shall
receive, at or prior to the time of such transaction's effectiveness, an
Officers' Certificate and an Opinion of Counsel providing that any such
consolidation or merger, or any sale, assignment, transfer, conveyance or other
disposition of all or substantially all the assets of the Company and its
Restricted Subsidiaries and any such assumption complies with the provisions of
this Article 14.

         IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

      Section 16.01. Indenture And Debentures Solely Corporate Obligations. No
recourse for the payment of the principal of, Interest on, or Additional
Amounts, if any, on, any Debenture, or for any claim based thereon or otherwise
in respect thereof, and no recourse under or upon any obligation, covenant or
agreement of the Company or any Subsidiary Guarantor in this Indenture or in any
supplemental indenture or in any Debenture, or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator,
stockholder, employee, agent, officer, director or Subsidiary, as such, past,
present or future, of the Company or Subsidiary Guarantor, as the case may be,
or of any successor corporation, either directly or through the Company, any
Subsidiary Guarantor or any successor corporation, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly understood that all such liability is
hereby expressly waived and released as a condition of, and as a consideration
for, the execution of this Indenture and the issue of the Debentures and
Subsidiary Guarantees.

                            CONVERSION OF DEBENTURES

      Section 17.01. Right To Convert. (a) Subject to and in accordance with
the provisions of this Indenture, prior to the close of business on the Business
Day immediately preceding March 15, 2025, the holder of any Debenture shall have
the right, at such holder's option, to convert the principal amount of the
Debenture, or any portion of such principal amount that is a multiple of $1,000,
into cash and fully paid and shares of Common Stock, if any, at a rate (the

                                       84
<PAGE>

"CONVERSION RATE") equivalent to 18.4493 shares of Common Stock (subject to
adjustment as provided in this Indenture) per $1,000 principal amount Debenture
under any of the following circumstances (the "CONVERSION OBLIGATION"):

            (i) during any Fiscal Quarter (but only during such Fiscal Quarter)
      commencing after June 30, 2005, if the Closing Price of the Common Stock
      exceeds 130% of the Conversion Price then in effect for at least twenty
      (20) Trading Days in the thirty (30) consecutive Trading Day period ending
      on the last Trading Day of the immediately preceding Fiscal Quarter (it
      being understood for purposes of this Section 17.01(a)(i) that the
      Conversion Price in effect at the close of business on each of the thirty
      (30) consecutive Trading Days should be used);

            (ii) during the five Business Day period immediately following any
      five consecutive Trading Day period (the "MEASUREMENT PERIOD") in which
      the Trading Price per $1,000 principal amount of the Debentures for each
      day of the Measurement Period was less than 95% of the product of the
      Closing Price of the Common Stock and the Conversion Rate then in effect
      (as determined following the provision by a Debentureholder of reasonable
      evidence that such condition has occurred in accordance with the
      procedures described below); provided, however, that the Debentures shall
      not be convertible pursuant to this clause (ii) if on any Trading Day
      during the Measurement Period the Closing Price of the Common Stock was
      between 100% and 130% of the then current Conversion Price;

            (iii) if the Debentures have been called for redemption, at any time
      on or after the date the notice of redemption has been given until the
      close of business on the Business Day immediately preceding the redemption
      date;

            (iv) as provided in Section 17.01(b); and

            (v) as provided in Section 17.01(c).

      The Company (or other conversion agent appointed by the Company) shall
determine on a daily basis during the time period specified in Section
17.01(a)(i) whether the Debentures shall be convertible as a result of the
occurrence of an event specified in clause (i) above. Whenever the Debentures
shall become convertible pursuant to this Section 17.01, the Company or, at the
Company's request, the Trustee in the name and at the expense of the Company,
shall notify the holders of the event triggering such convertibility in the
manner provided in Section 18.03, and the Company shall also publicly announce
such information and publish such information on the Company's web site or
through such other public medium as the Company shall use at such time. Any
notice so given shall be conclusively presumed to have been duly given, whether
or not the holder receives such notice.

                                       85
<PAGE>

      The Trustee (or other conversion agent appointed by the Company) shall
have no obligation to determine the Trading Price under Section 17.01(a)(ii)
unless the Company has requested such a determination, and the Company shall
have no obligation to make such request unless a holder provides it with
reasonable evidence that the Trading Price per $1,000 principal amount of
Debentures would be less than 95% of the product of the Closing Price of the
Common Stock and the Conversion Rate then in effect. If such evidence is
provided, the Company shall instruct the Trustee (or other conversion agent) to
determine at the expense of the Company the Trading Price of the Debentures
beginning on the next Trading Day and on each successive Trading Day until the
Trading Price per $1,000 principal amount of Debentures is greater than or equal
to 95% of the product of the Closing Price of the Common Stock and the
Conversion Rate then in effect; provided that the Trustee shall be under no duty
or obligation to make the calculations described in Section 17.01(a)(ii) hereof
or to determine whether the Debentures are convertible pursuant to such section.
For the avoidance of doubt, the Company shall make the calculations described in
Section 17.01(a)(ii), using the Trading Price provided by the Trustee.

      The Trustee shall be entitled at its sole discretion to consult with the
Company and to request the assistance of the Company in connection with the
Trustee's duties and obligations pursuant to Section 17.01(a)(ii) hereof
(including without limitation the determination of the Conversion Rate, the
Closing Prices of the Common Stock and the Trading Price), and the Company
agrees, if requested by the Trustee, to cooperate with, and provide assistance
to, the Trustee in carrying out its duties under this Section 17.01; provided,
however, that nothing herein shall be construed to relieve the Trustee of its
duties pursuant to Section 17.01(a) hereof.

      (b) In addition, if:

            (i) (A) the Company distributes to all holders of its Common Stock
      rights, warrants or options entitling them (for a period expiring within
      forty-five (45) days of the record date for the determination of the
      stockholders entitled to receive such distribution) to subscribe for or
      purchase shares of Common Stock, at a price per share less than the
      average of the Closing Prices of the Common Stock for the ten (10) Trading
      Days immediately preceding, but not including, the declaration date for
      such distribution, or (B) the Company distributes to all holders of its
      Common Stock, assets, debt securities or rights to purchase its securities
      (other than the rights, warrants or options referred to in clause (A)
      above), where the Fair Market Value of such distribution per share of
      Common Stock exceeds 10% of the Closing Price of the Common Stock on the
      Trading Day immediately preceding the declaration date for such
      distribution, then, in either case, the Debentures may be surrendered for
      conversion at any time on and after the date that the Company gives notice
      to the holders of such distribution, which shall be not less than twenty
      (20) days prior to the Ex-Dividend Time for such distribution, until the
      earlier

                                       86
<PAGE>

      of the close of business on the Business Day immediately preceding, but
      not including, the Ex-Dividend Time or the date the Company publicly
      announces that such distribution will not take place; provided that no
      adjustment to the Conversion Rate will be made nor will a holder of a
      Debenture be able to convert pursuant to this Section 17.01(b) if such
      holder will otherwise participate in such distribution without conversion;
      or

            (ii) the Company consolidates with or merges with or into another
      Person or is a party to a binding share exchange, in each case pursuant to
      which the Common Stock is converted into cash, securities or other
      property, then the Debentures may be surrendered for conversion at any
      time from and after the date fifteen (15) days prior to the anticipated
      effective date of the transaction and ending on and including the date
      fifteen (15) days after the consummation of the transaction, unless such
      transaction occurs on or prior to March 20, 2010 and also constitutes a
      Make Whole Event (in which case the Debentures will be convertible in
      accordance with Section 17.01(c)). The Company shall notify holders and
      the Trustee (whether or not such transaction also constitutes a Make Whole
      Event) at the same time the Company publicly announces such transaction
      (but in no event less than 15 days prior to the effective date of such
      transaction). Following the effective date of such transaction, the right
      to convert the Debentures at the Conversion Rate, and the settlement
      thereof, shall be modified as set forth under Section 17.06.

      "EX-DIVIDEND TIME" means, with respect to any distribution on shares of
Common Stock, the first date on which the shares of Common Stock trade regular
way on the principal securities market on which the shares of Common Stock are
then traded without the right to receive such distribution.

      (c) (i) In the event that a Make Whole Event occurs on or prior to March
20, 2010, the Company must provide notice of the anticipated effective date of
such Make Whole Event to the holders of Debentures and to the Trustee on a date
(the "EFFECTIVE DATE NOTICE") that is at least ten (10) Trading Days prior to
such anticipated effective date. The Company shall also provide notice to the
holders of Debentures and to the Trustee that such Make Whole Event has become
effective within 15 days after such effective date. A holder may surrender
Debentures for conversion pursuant to Section 17.01(c) at any time during the
period from the opening of business on the date the Company provides the
Effective Date Notice until the Designated Event Repurchase Date relating to
such Make Whole Event. The Effective Date Notice will specify whether the
Company made the election set forth in Section 17.01(d) hereof.

            (ii) If and only to the extent a holder timely elects to convert
      Debentures in connection with a Make Whole Event that occurs prior to
      March 20, 2010, the Conversion Rate for such converting holder shall be

                                       87
<PAGE>

      increased by an additional number of shares of Common Stock (the
      "ADDITIONAL SHARES") as described below.

      The number of Additional Shares issuable in connection with the conversion
of Debentures as described in the immediately preceding paragraph shall be
determined by reference to the table attached as Schedule A to this Indenture,
based on the effective date of such Make Whole Event (the "EFFECTIVE DATE") and
the Stock Price paid in connection with such transaction; provided that if the
Stock Price is between two Stock Price amounts in the table or such Effective
Date is between two Effective Dates in the table, the number of Additional
Shares shall be determined by a straight-line interpolation between the number
of Additional Shares set forth for the next higher and next lower Stock Price
amounts and the two nearest Effective Dates, as applicable, based on a 365-day
year; provided further that if the Stock Price is above $130.00 per share of
Common Stock (subject to adjustment), no Additional Shares will be added to the
Conversion Rate; and provided that if the Stock Price is below $40.15 per share
(subject to adjustment), no Additional Shares will be added to the Conversion
Rate.

      The Stock Prices set forth in the first row of the table in Schedule A to
this Indenture shall be adjusted as of any date on which the Conversion Rate of
the Debentures is adjusted. The adjusted Stock Prices shall equal the Stock
Prices applicable immediately prior to such adjustment, multiplied by a
fraction, the numerator of which is the Conversion Rate immediately prior to the
adjustment giving rise to the Stock Price adjustment and the denominator of
which is the Conversion Rate as so adjusted. The number of Additional Shares
within the table shall be adjusted in the same manner as the Conversion Rate as
set forth in Section 17.05 (other than by operation of an adjustment to the
Conversion Rate by adding Additional Shares).

      Notwithstanding the foregoing, in no event shall the total number of
shares of Common Stock issuable upon conversion exceed 24.9066 shares per $1,000
principal amount of Debentures, subject to adjustment in the same manner as the
Conversion Rate as set forth in Section 17.05.

      The Additional Shares will be delivered to holders who elect to convert
their Debentures on the later of (1) the fifth business day following the
Effective Date and (2) the Conversion Settlement Date.

      Any conversion of Debentures in connection with a Make Whole Event as
provided in this subsection, and the settlement thereof, shall be as set forth
in Section 17.06.

      (d) Notwithstanding the foregoing, and in lieu of adjusting the Conversion
Rate as set forth in Section 17.01(c), in the case of a Public Acquirer Change
of Control, the Company may elect that, from and after the Effective Date of
such Public Acquirer Change of Control, the right to convert a Debenture will

                                       88
<PAGE>

be changed into a right to convert a Debenture into a number of shares of
Acquirer Common Stock specified below. The Conversion Rate following the
Effective Date of such Public Acquirer Change of Control shall be a number of
shares of Acquirer Common Stock equal to the product of:

            (i) the Conversion Rate in effect immediately prior to the Effective
      Date of such Public Acquirer Change of Control, times

            (ii) the average of the quotients obtained, for each Trading Day in
      the 10 consecutive Trading Day period commencing on the Trading Day next
      succeeding the Effective Date of such Public Acquirer Change of Control
      (the "VALUATION PERIOD"), of:

                  (A) the Acquisition Value of Common Stock on each such Trading
            Day in the Valuation Period, divided by

                  (B) the Closing Price of the Acquirer Common Stock on each
            such Trading Day in the Valuation Period.

      After an adjustment of the Conversion Rate in connection with a Public
Acquirer Change of Control, the Conversion Rate will be subject to further
similar adjustments in the event that any of the events described in Section
17.05 or Section 17.06 occur thereafter.

      (e) A Debenture in respect of which a holder is electing to exercise its
option to require repurchase upon a Designated Event pursuant to Section 3.05 or
repurchase pursuant to Section 3.06 may be converted only if such holder
withdraws its election in accordance with Section 3.05(d) or Section 3.08,
respectively. A holder of Debentures is not entitled to any rights of a holder
of Common Stock until such holder has received the Common Stock, if any, due to
it upon conversion of the Debentures, and only to the extent such Debentures are
deemed to have been converted into Common Stock under this Article 17.

      Section 17.02. Conversion Procedures. (a) Upon conversion of any
Debenture, subject to this Section 17.02, Section 17.01(c) and Section 17.06,
the Company shall satisfy the Conversion Obligation with respect to such
Debenture by payment and delivery of cash and, if applicable, shares of Common
Stock, the aggregate value (the "CONVERSION VALUE") of which shall be equal to
the product of:

            (i) (A) the aggregate principal amount of Debentures to be converted
      divided by 1,000, multiplied by (B) the then applicable Conversion Rate;
      and

            (ii) the average of the Closing Prices of Common Stock for each of
      the ten (10) consecutive Trading Days (appropriately adjusted to take into
      account the occurrence during such period of stock splits and similar
      events) beginning on the second Trading Day immediately

                                       89
<PAGE>

      following the day the Debentures are tendered for conversion (the "TEN DAY
      AVERAGE PRICE").

      (b) The Company shall deliver the Conversion Value to converting holders
as follows:

            (i) an amount in cash (the "PRINCIPAL RETURN") equal to the lesser
      of (A) the Conversion Value of the Debentures to be converted and (B) the
      aggregate principal amount of the Debentures to be converted;

            (ii) if the Conversion Value of the Debentures to be converted is
      greater than the Principal Return, an amount in whole shares of Common
      Stock (the "NET SHARES"), determined as set forth below, equal to such
      aggregate Conversion Value less the Principal Return (the "NET SHARE
      AMOUNT"); and

            (iii) an amount in cash, in lieu of any fractional shares of Common
      Stock as set forth below.

      The number of Net Shares to be paid shall be determined by dividing the
Net Share Amount by the Ten Day Average Price. Holders of Debentures will not
receive fractional shares upon conversion of Debentures. In lieu of fractional
shares, holders will receive cash for the value of the fractional shares, which
cash payment shall be based on the Ten Day Average Price.

      The Conversion Value, Principal Return, number of Net Shares and Net Share
Amount shall be determined by the Company at the end of the ten consecutive
Trading Day period (the "CONVERSION DETERMINATION DATE") beginning on the second
Trading Day immediately following the day the Debentures are tendered for
conversion.

      If upon conversion of Debentures by any holder, the Company is not
permitted to pay the Principal Return in cash due to the limitations imposed by
the Senior Credit Agreement, the Company shall, within three Business Days of
the relevant Conversion Date, provide notice to such converting holder and the
Trustee that the Company is not permitted to pay such Principal Return due to
the limitations imposed by the Senior Credit Agreement, and such holder shall
have the option to revoke its notice of conversion during the three Business Day
period following delivery of such notice.

      (c) Before any holder of a Debenture shall be entitled to convert the same
as set forth above, such holder shall (1) in the case of Global Debentures,
comply with the procedures of the Depositary in effect at that time and furnish
appropriate endorsement and transfer documents, and (2) in the case of a
Debenture issued in certificated form, surrender such Debentures, duly endorsed
to the Company or in blank (and accompanied by appropriate endorsement and
transfer documents), at the office of the conversion agent, and give irrevocable
written notice to the conversion agent in the form on the reverse of such

                                       90
<PAGE>

certificated Debenture (or a facsimile thereof) (a "NOTICE OF CONVERSION") at
said office or place that such holder elects to convert the same and shall state
in writing therein the principal amount of Debentures to be converted and the
name or names (with addresses) in which such holder wishes the certificate or
certificates for the Net Shares, if any, included upon settlement the Conversion
Obligation, if any, to be registered. No Notice of Conversion with respect to
any Debentures may be tendered by a holder thereof if such holder has also
tendered a Repurchase Notice or Option to Elect Repurchase Upon a Designated
Event and not validly withdrawn such Repurchase Notice or Option to Elect
Repurchase Upon a Designated Event in accordance with Article 3.

      If more than one Debenture shall be surrendered for conversion at one time
by the same holder, the Conversion Obligation with respect to such Debentures,
if any, that shall be payable upon conversion shall be computed on the basis of
the aggregate principal amount of the Debentures (or specified portions thereof
to the extent permitted thereby) so surrendered.

      (d) A Debenture shall be deemed to have been converted immediately prior
to the close of business on the date (the "CONVERSION DATE") that is the later
of: (i) the date the holder has complied with the requirements set forth in
clause (c) above or (ii) the Conversion Determination Date. Payment of the cash
and Net Shares, if any, in satisfaction of the Conversion Obligation shall be
made by the Company promptly following the Conversion Date, but in no event
later than three Business Days thereafter (the "CONVERSION SETTLEMENT DATE") by
paying, in cash, the Principal Return (together with any cash in lieu of
fractional shares) to the holder of a Debenture surrendered for conversion, or
such holder's nominee or nominees, and issue, or cause to be issued, and
delivering to the conversion agent or to such holder, or such holder's nominee
or nominees, certificates or a book-entry transfer through the Depositary for
the number of full shares of Common Stock equal to the Net Shares, if any, to
which such holder shall be entitled as part of such Conversion Obligation.

      (e) In case any Debenture shall be surrendered for partial conversion, the
Company shall execute and, upon written direction of the Company, the Trustee
shall authenticate and deliver to or upon the written order of the holder of the
Debenture so surrendered, without charge to such holder, a new Debenture or
Debentures in authorized denominations in an aggregate principal amount equal to
the unconverted portion of the surrendered Debentures.

      (f) If a holder submits a Debenture for conversion, the Company shall pay
all stamp and other duties, if any, which may be imposed by the United States or
any political subdivision thereof or taxing authority thereof or therein with
respect to the issuance of shares of Common Stock, if any, upon the conversion.
However, the holder shall pay any such tax which is due because the holder
requests any Net Shares to be issued in a name other than the holder's name. The
Trustee may refuse to deliver the certificates representing the shares of Common
Stock being issued in a name other than the holder's name until the Trustee

                                       91
<PAGE>

receives a sum sufficient to pay any tax which will be due because the shares
are to be issued in a name other than the holder's name. Nothing herein shall
preclude any tax withholding required by law or regulations.

      (g) Upon the conversion of an interest in a Global Debenture, the Trustee,
or the Custodian at the direction of the Trustee, shall make a notation on such
Global Debenture as to the reduction in the principal amount represented
thereby. The Company shall notify the Trustee in writing of any conversion of
Debentures effected through any conversion agent other than the Trustee.

      (h) No payment or adjustment shall be made for dividends on, or other
distributions with respect to, any Common Stock except as provided in this
Article 17. Upon conversion of a Debenture, except for conversion during the
period from the close of business on any record date immediately preceding any
interest payment date to the close of business on the Business Day immediately
preceding such interest payment date, in which case the holder on such record
date shall receive the Interest and Additional Amounts, if any, payable on such
interest payment date, that portion of accrued and unpaid Interest and
Additional Amounts, if any, on the converted Debenture attributable to the
period from the most recent interest payment date (or, if no interest payment
date has occurred, from the Issue Date) through the Conversion Date shall not be
cancelled, extinguished or forfeited, but rather shall be deemed to be paid in
full to the holder thereof through delivery of the Common Stock (together with
the cash payment, if any, in lieu of fractional shares), or cash or a
combination of cash and Common Stock in lieu thereof, in exchange for the
Debenture being converted pursuant to the provisions hereof, and the Fair Market
Value of such shares of Common Stock (together with any such cash payment in
lieu of fractional shares) shall be treated as issued, to the extent thereof,
first in exchange for accrued and unpaid Interest and Additional Amounts, if
any, accrued through the Conversion Date and the balance, if any, of such Fair
Market Value of such Common Stock (and any such cash payment) shall be treated
as issued in exchange for the principal amount of the Debenture being converted
pursuant to the provisions hereof.

      (i) Debentures or portions thereof surrendered for conversion during the
period from the close of business on any record date immediately preceding any
interest payment date to the close of business on the Business Day immediately
preceding such interest payment date shall be accompanied by payment to the
Company or its order, in immediately available funds or other funds acceptable
to the Company, of an amount equal to the Interest and Additional Amounts, if
any, payable on such interest payment date with respect to the principal amount
of Debentures or portions thereof being surrendered for conversion; provided
that no such payment need be made (1) if the Company has specified a redemption
date that occurs after a record date but on or prior to the next interest
payment date, (2) if the Company has specified a Designated Event Repurchase
Date during such period or (3) to the extent of any overdue Interest or

                                       92
<PAGE>

overdue Additional Amounts, if any overdue Interest or Additional Amounts exist
on the Conversion Date with respect to the Debentures converted.

      (j) Notwithstanding the foregoing, if on any Conversion Date, the Company
is required to pay Additional Amounts pursuant to the Registration Rights
Agreement, the Conversion Rate on such date shall be multiplied by 1.03.

      (k) Notwithstanding the foregoing, no adjustment to the Conversion Rate
will be made in connection with a merger, consolidation or other transaction
effected solely for the purpose of changing the Company's jurisdiction of
incorporation to any other state within the United States.

      Section 17.03. Conversion Obligation Upon a Bankruptcy. Notwithstanding
the provisions of Section 17.02, if an event of bankruptcy involving the Company
has occurred and is continuing, in lieu of delivering the Principal Return in
cash and any Net Share Amount in shares of Common Stock, the Company will have
the right to deliver the Conversion Value to holders in cash, shares of Common
Stock or a combination of cash and shares of Common Stock at its option.

      Section 17.04. [Reserved].

      Section 17.05. Adjustment Of Conversion Rate. The Conversion Rate shall be
adjusted from time to time (without duplication) by the Company as follows:

      (a) In case the Company shall hereafter pay a dividend or make a
distribution to all holders of the outstanding Common Stock in shares of Common
Stock, the Conversion Rate shall be increased so that the same shall equal the
rate determined by multiplying the Conversion Rate in effect immediately prior
to the opening of business on the day following the date fixed for the
determination of stockholders entitled to receive such dividend or other
distribution by a fraction,

            (i) the numerator of which shall be the sum of the number of shares
      of Common Stock outstanding at the close of business on the date fixed for
      the determination of stockholders entitled to receive such dividend or
      other distribution plus the total number of shares of Common Stock
      constituting such dividend or other distribution; and

            (ii) the denominator of which shall be the number of shares of
      Common Stock outstanding at the close of business on the date fixed for
      such determination,

such increase to become effective immediately after the opening of business on
the day following the date fixed for such determination. For the purpose of this
paragraph (a), the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company. The Company will
not pay any dividend or make any distribution on shares of Common Stock held

                                       93
<PAGE>

in the treasury of the Company. If any dividend or distribution of the type
described in this Section 17.05(a) is declared but not so paid or made, the
Conversion Rate shall again be adjusted to the Conversion Rate that would then
be in effect if such dividend or distribution had not been declared.

      (b) In case the Company shall issue rights, options or warrants to all
holders of its outstanding shares of Common Stock entitling them (for a period
expiring within forty-five (45) days after the date fixed for determination of
stockholders entitled to receive such rights, options or warrants) to subscribe
for or purchase shares of Common Stock at a price per share less than the
average of the Closing Prices of the Common Stock for the ten (10) Trading Days
immediately preceding the declaration date for such distribution, the Conversion
Rate shall be increased so that the same shall equal the rate determined by
multiplying the Conversion Rate in effect immediately prior to the opening of
business on the day following the date fixed for determination of stockholders
entitled to receive such rights, options or warrants by a fraction,

            (i) the numerator of which shall be the number of shares of Common
      Stock outstanding at the close of business on the date fixed for
      determination of stockholders entitled to receive such rights, options or
      warrants plus the total number of additional shares of Common Stock
      offered for subscription or purchase, and

            (ii) the denominator of which shall be the sum of the number of
      shares of Common Stock outstanding at the close of business on the date
      fixed for determination of stockholders entitled to receive such rights,
      options or warrants plus the number of shares that the aggregate offering
      price of the total number of shares of Common Stock so offered would
      purchase at a price equal to the average of the Closing Prices of the
      Common Stock for the ten (10) Trading Days immediately preceding the
      declaration date for such distribution.

      Such adjustment shall be successively made whenever any such rights,
options or warrants are issued, and shall become effective immediately after the
opening of business on the day following the date fixed for determination of
stockholders entitled to receive such rights, options or warrants. To the extent
that shares of Common Stock are not delivered after the expiration of such
rights, options or warrants, the Conversion Rate shall be readjusted to the
Conversion Rate that would then be in effect had the adjustments made upon the
issuance of such rights, options or warrants been made on the basis of delivery
of only the number of shares of Common Stock actually delivered. If such rights,
options or warrants are not so issued, the Conversion Rate shall again be
adjusted to be the Conversion Rate that would then be in effect if such date
fixed for the determination of stockholders entitled to receive such rights,
options or warrants had not been fixed. In determining whether any rights,
options or warrants entitle the holders to subscribe for or purchase shares of
Common Stock at a price less than the average of the Closing Prices of the
Common Stock for the ten (10)

                                       94
<PAGE>

Trading Days immediately preceding the declaration date for such distribution,
and in determining the aggregate offering price of such shares of Common Stock,
there shall be taken into account any consideration received by the Company for
such rights, options or warrants and any amount payable on exercise or
conversion thereof, the value of such consideration, if other than cash, to be
determined by the Board of Directors of the Company.

      (c) In case outstanding shares of Common Stock shall be subdivided into a
greater number of shares of Common Stock, the Conversion Rate in effect at the
opening of business on the day following the day upon which such subdivision
becomes effective shall be proportionately increased, and conversely, in case
outstanding shares of Common Stock shall be combined into a smaller number of
shares of Common Stock, the Conversion Rate in effect immediately prior to the
opening of business on the day following the day upon which such combination
becomes effective shall be proportionately reduced, such increase or reduction,
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.

      (d) In case the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock shares of any class of capital stock of the Company
or evidences of its indebtedness, property or assets (including rights, options,
warrants and other securities, but excluding any rights, options or warrants
referred to in Section 17.05(b), and excluding any dividend or distribution (x)
paid exclusively in cash or (y) referred to in Section 17.05(a)) (any of the
foregoing hereinafter in this Section 17.05(d) called the "DISTRIBUTED
PROPERTY"), then, in each such case the Conversion Rate shall be increased so
that the same shall be equal to the rate determined by multiplying the
Conversion Rate in effect immediately prior to the opening of business on the
day immediately following the Record Date with respect to such distribution by a
fraction,

            (i) the numerator of which shall be the Current Market Price on such
      Record Date; and

            (ii) the denominator of which shall be the Current Market Price on
      such Record Date less the Fair Market Value (as determined by the Board of
      Directors of the Company, whose determination shall be conclusive, and
      described in a resolution of such Board of Directors) on the Record Date
      of the portion of the Distributed Property so distributed applicable to
      one share of Common Stock,

such adjustment to become effective immediately after the opening of business on
the day following such Record Date; provided that if the then Fair Market Value
(as so determined) of the portion of the Distributed Property so distributed
applicable to one share of Common Stock is equal to or greater than the Current
Market Price on the Record Date, in lieu of the foregoing adjustment, upon any
conversion of the Debentures thereafter, the provisions of Section 17.06 shall

                                       95
<PAGE>

apply to such conversion mutatis mutandis; provided further that for such
application, any references in such provisions to the "Exchange Property" shall
be deemed references to a unit composed of (a) the number of shares of Common
Stock equal to the Conversion Rate immediately prior to the relevant
distribution and (b) the amount of Distributed Property such holder would have
received had such holder held a number of shares of Common Stock equal to the
Conversion Rate immediately prior to the relevant distribution. If such dividend
or distribution is not so paid or made, the Conversion Rate shall again be
adjusted to be the Conversion Rate that would then be in effect if such dividend
or distribution had not been declared. If the Board of Directors of the Company
determines the Fair Market Value of any distribution for purposes of this
Section 17.05(d) by reference to the actual or when issued trading market for
any securities, it must in doing so consider the prices in such market over the
same period used in computing the Current Market Price on the applicable Record
Date.

      Notwithstanding the foregoing, if the Distributed Property distributed by
the Company to all holders of its Common Stock consist of capital stock of, or
similar equity interests in, a Subsidiary or other business unit of the Company,
the Conversion Rate shall be increased so that the same shall be equal to the
rate determined by multiplying the Conversion Rate in effect immediately prior
to the opening of business on the day following the Record Date with respect to
such distribution by a fraction,

            (i) the numerator of which shall be the sum of (A) the average of
      the Closing Prices of the Common Stock for the ten (10) consecutive
      Trading Days commencing on and including the fifth Trading Day after the
      date on which "ex-dividend trading" commences for such dividend or
      distribution on the New York Stock Exchange, the Nasdaq National Market or
      such other national or regional exchange or market on which such
      securities are then listed or quoted (the "EX-DIVIDEND DATE") plus (B) the
      average Closing Prices of the securities distributed in respect of each
      share of Common Stock for the ten (10) consecutive Trading Days commencing
      on and including the fifth Trading Day after the Ex-Dividend Date; and

            (ii) the denominator of which shall be the average of the Closing
      Prices of the Common Stock for the ten (10) consecutive Trading Days
      commencing on and including the fifth Trading Day after the Ex-Dividend
      Date,

such adjustment to become effective immediately after the opening of business on
the day following such Record Date; provided that if (x) the average of the
Closing Prices of the Common Stock for the ten (10) consecutive Trading Days
commencing on and including the fifth Trading Day after the Ex-Dividend Date
minus (y) the average of the Closing Prices of the securities distributed in
respect of each share Common Stock for the ten (10) consecutive Trading Days

                                       96
<PAGE>

commencing on and including the fifth Trading Day after the Ex-Dividend Date is
less than $1.00, then the adjustment provided by for by this paragraph shall not
be made and in lieu thereof the provisions of the first paragraph of this
Section 17.05(d) shall apply to such distribution. In any case in which this
paragraph is applicable, Section 17.05(a), Section 17.05(b) and the first
paragraph of this Section 17.05(d) shall not be applicable.

      Rights or warrants distributed by the Company to all holders of Common
Stock entitling the holders thereof to subscribe for or purchase shares of the
Company's capital stock (either initially or under certain circumstances), which
rights, options or warrants, until the occurrence of a specified event or events
("TRIGGER EVENT"): (i) are deemed to be transferred with such shares of Common
Stock; (ii) are not exercisable; and (iii) are also issued in respect of future
issuances of Common Stock, shall be deemed not to have been distributed for
purposes of this Section 17.05 (and no adjustment to the Conversion Rate under
this Section 17.05 will be required) until the occurrence of the earliest
Trigger Event, whereupon such rights, options and warrants shall be deemed to
have been distributed and an appropriate adjustment (if any is required) to the
Conversion Rate shall be made under this Section 17.05(d). If any such right or
warrant, including any such existing rights, options or warrants distributed
prior to the date of this Indenture, are subject to events, upon the occurrence
of which such rights, options or warrants become exercisable to purchase
different securities, evidences of indebtedness or other assets, then the date
of the occurrence of any and each such event shall be deemed to be the date of
distribution and record date with respect to new rights, options or warrants
with such rights (and a termination or expiration of the existing rights,
options or warrants without exercise by any of the holders thereof). In
addition, in the event of any distribution (or deemed distribution) of rights,
options or warrants, or any Trigger Event or other event (of the type described
in the preceding sentence) with respect thereto that was counted for purposes of
calculating a distribution amount for which an adjustment to the Conversion Rate
under this Section 17.05 was made, (1) in the case of any such rights, options
or warrants that shall all have been redeemed or repurchased without exercise by
any holders thereof, the Conversion Rate shall be readjusted upon such final
redemption or repurchase to give effect to such distribution or Trigger Event,
as the case may be, as though it were a cash distribution, equal to the per
share redemption or repurchase price received by a holder or holders of Common
Stock with respect to such rights, options or warrants (assuming such holder had
retained such rights, options or warrants), made to all holders of Common Stock
as of the date of such redemption or repurchase, and (2) in the case of such
rights, options or warrants that shall have expired or been terminated without
exercise by any holders thereof, the Conversion Rate shall be readjusted as if
such rights, options and warrants had not been issued.

      Prior to the occurrence of any Triggering Event, no adjustment to the
Conversion Rate shall be made pursuant to this Section 17.05(d) in respect of
rights, options or warrants distributed to or deemed distributed upon the
occurrence of such Triggering Event to the extent such rights, options or
warrants

                                       97
<PAGE>

are actually distributed, or reserved by the Company for distribution, to
holders of Debentures upon conversion by such holders of Debentures into Common
Stock.

      For purposes of this Section 17.05(d), Section 17.05(a) and Section
17.05(b), any dividend or distribution to which this Section 17.05(d) is
applicable that also includes shares of Common Stock, or rights, options or
warrants to subscribe for or purchase shares of Common Stock (or both), shall be
deemed instead to be (1) a dividend or distribution of the evidences of
indebtedness, assets or shares of capital stock other than such shares of Common
Stock or rights, options or warrants (and any Conversion Rate adjustment
required by this Section 17.05(d) with respect to such dividend or distribution
shall then be made) immediately followed by (2) a dividend or distribution of
such shares of Common Stock or such rights, options or warrants (and any further
Conversion Rate adjustment required by Sections 17.05(a) and 17.05(b) with
respect to such dividend or distribution shall then be made), except (A) the
Record Date of such dividend or distribution shall be substituted as "the date
fixed for the determination of stockholders entitled to receive such dividend or
other distribution", "the date fixed for the determination of stockholders
entitled to receive such rights, options or warrants" and "the date fixed for
such determination" within the meaning of Section 17.05(a) and 17.05(b) and (B)
any shares of Common Stock included in such dividend or distribution shall not
be deemed "outstanding at the close of business on the date fixed for the
determination of stockholders entitled to receive such dividend or other
distribution" or "outstanding at the close of business on the date fixed for
such determination" within the meaning of Section 17.05(a).

      The reclassification of the Common Stock into securities including
securities other than Common Stock (other than any reclassification upon an
event to which Section 17.06 applies) shall be deemed to involve (a) a
distribution of such securities other than the Common Stock to all holders of
Common Stock (and the effective date of such reclassification shall be deemed to
be the "Record Date" within the meaning of this Section 17.05(d)), 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 Section
17.05(c)).

      (e) In case the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock cash (excluding any dividend or distribution in
connection with the liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary), then, in such case, the Conversion Rate shall
be increased so that the same shall equal the rate determined by multiplying the
Conversion Rate in effect immediately prior to the opening of business on the
day following such Record Date by a fraction,

                                       98
<PAGE>

            (i) the numerator of which shall be the Current Market Price on such
      Record Date; and

            (ii) the denominator of which shall be the Current Market Price on
      such Record Date less the amount of cash so distributed applicable to one
      share of Common Stock,

such adjustment to be effective immediately after the opening of business on the
day following the Record Date; provided that if the portion of the cash so
distributed applicable to one share of Common Stock is equal to or greater than
the Current Market Price on the Record Date, in lieu of the foregoing
adjustment, upon any conversion of the Debentures thereafter, the provisions of
Section 17.06 shall apply to such conversion mutatis mutandis; provided further
that for such application, any references in such provisions to the "Exchange
Property" shall be deemed references to a unit composed of (a) the number of
shares of Common Stock equal to the Conversion Rate immediately prior to the
relevant distribution and (b) the amount of cash such holder would have received
had such holder held a number of shares of Common Stock equal to the Conversion
Rate immediately prior to the relevant distribution. Notwithstanding anything
contained in this Section 17.05(e), in no event will the Conversion Rate exceed
24.9066 per $1,000 principal amount of the debentures (the "MAXIMUM CONVERSION
RATE") as a result of an adjustment pursuant to this Section 17.05(e); provided,
however, that the Maximum Conversion Rate is subject to adjustment in accordance
with Sections 17.05(a), (b), (c), (d), and (f). If such dividend or distribution
is not so paid or made, the Conversion Rate shall again be adjusted to be the
Conversion Rate that would then be in effect if such dividend or distribution
had not been declared.

      (f) In case a tender or exchange offer made by the Company or any
Subsidiary for all or any portion of the Common Stock shall expire and such
tender or exchange offer (as amended upon the expiration thereof) shall require
the payment to stockholders of consideration per share of Common Stock having a
Fair Market Value (as determined by the Board of Directors of the Company, whose
determination shall be conclusive and described in a resolution of the Board of
Directors) that as of the last time (the "EXPIRATION TIME") tenders or exchanges
may be made pursuant to such tender or exchange offer (as it may be amended)
exceeds the Closing Price per share of Common Stock on the Trading Day next
succeeding the Expiration Time, the Conversion Rate shall be increased so that
the same shall equal the rate determined by multiplying the Conversion Rate in
effect immediately prior to the Expiration Time by a fraction,

            (i) the numerator of which shall be the sum of (x) the Fair Market
      Value (determined as aforesaid) of the aggregate consideration payable to
      stockholders based on the acceptance (up to any maximum specified in the
      terms of the tender or exchange offer) of all shares validly tendered or
      exchanged and not withdrawn as of the Expiration Time (the shares deemed
      so accepted up to any such maximum, being referred to as

                                       99
<PAGE>

      the "PURCHASED SHARES") and (y) the product of the number of shares of
      Common Stock outstanding (less any Purchased Shares) at the Expiration
      Time and the Closing Price per share of Common Stock on the Trading Day
      next succeeding the Expiration Time, and

            (ii) the denominator of which shall be the number of shares of
      Common Stock outstanding (including any tendered or exchanged shares) at
      the Expiration Time multiplied by the Closing Price per share of Common
      Stock on the Trading Day next succeeding the Expiration Time,

such adjustment to become effective immediately after the Expiration Time. If
the Company is obligated to purchase shares pursuant to any such tender or
exchange offer, but the Company is permanently prevented by applicable law from
effecting any such purchases or all such purchases are rescinded, the Conversion
Rate shall again be adjusted to be the Conversion Rate that would then be in
effect if such tender or exchange offer had not been made.

      (g) No adjustment in the Conversion Rate shall be made for any increase or
decrease in the par value of the Common Stock, or a change in the par value of
the Common Stock to no par value.

      (h) [Reserved.]

      (i) For purposes of this Section 17.05, the following terms shall have the
meaning indicated:

            (i) "CURRENT MARKET PRICE" means the average of the daily Closing
      Prices per share of Common Stock for the ten (10) consecutive Trading Days
      ending on the earlier of the date of termination and the day before the
      "EX" date with respect to the distribution requiring such computation. For
      purpose of this paragraph, the term "EX" date, when used with respect to
      any distribution, means the first date on which the Common Stock trades,
      regular way, on the relevant exchange or in the relevant market from which
      the Closing Price was obtained without the right to receive such
      distribution.

      If another issuance, distribution, subdivision or combination to which
      Section 17.05 applies occurs during the period applicable for calculating
      "Current Market Price" pursuant to the definition in the preceding
      paragraph, "Current Market Price" shall be calculated for such period in a
      manner determined by the Board of Directors of the Company to reflect the
      impact of such issuance, distribution, subdivision or combination on the
      Closing Price of the Common Stock during such period.

            (ii) "FAIR MARKET VALUE" shall mean the amount that a willing buyer
      would pay a willing seller in an arm's-length transaction.

                                      100
<PAGE>

            (iii) "RECORD DATE" shall mean, with respect to any dividend,
      distribution or other transaction or event in which the holders of Common
      Stock have the right to receive any cash, securities or other property or
      in which the Common Stock (or other applicable security) is exchanged for
      or converted into any combination of cash, securities or other property,
      the date fixed for determination of stockholders entitled to receive such
      cash, securities or other property (whether such date is fixed by the
      Board of Directors of the Company or by statute, contract or otherwise).

            (iv) "TRADING DAY" for any security shall mean (x) if the applicable
      security is listed or admitted for trading on the New York Stock Exchange
      or another national securities exchange, a day on which the New York Stock
      Exchange or another national securities exchange is open for business, or
      (y) if the applicable security is quoted on the Nasdaq National Market, a
      day on which trades may be made thereon, or (z) if the applicable security
      is not so listed, admitted for trading or quoted, any day other than a
      Saturday or Sunday or a day on which banking institutions in the State of
      New York are authorized or obligated by law or executive order to close.

      (j) The Company may make such increases in the Conversion Rate, in
addition to those required by Section 17.05(a), (b), (c), (d), (e) or (f) as the
Board of Directors of the Company considers to be advisable to avoid or diminish
any income tax to holders of Common Stock or rights to purchase Common Stock
resulting from any dividend or distribution of stock (or rights to acquire
stock) or from any event treated as such for income tax purposes. To the extent
permitted by applicable law, the Company from time to time may increase the
Conversion Rate by any amount for any period of time if the Board of Directors
of the Company shall have made a determination that such increase would be in
the best interests of the Company, which determination shall be conclusive.
Notwithstanding the foregoing, in no event will the total number of shares of
common stock issuable upon conversion exceed 24.9066 per $1,000 principal amount
of the Debentures, subject to adjustments in the same manner as the Conversion
Rate pursuant to Section 17.05.

      Whenever the Conversion Rate is increased pursuant to the preceding
paragraph, the Company shall mail, or cause the Trustee to mail at the Company's
expense, to holders of record of the Debentures a notice of the increase prior
to the date the increased Conversion Rate takes effect, and such notice shall
state the increased Conversion Rate and the period during which it will be in
effect.

      (k) All calculations under this Article 17 shall be made by the Company
and shall be made to the nearest cent or to the nearest one-ten thousandth
(1/10,000) of a share, as the case may be. No adjustment need be made for rights
to purchase Common Stock pursuant to a Company plan for reinvestment of
dividends or interest or for any issuance of Common Stock or convertible or
exchangeable securities or rights to purchase Common Stock or convertible or

                                      101
<PAGE>

exchangeable securities. Interest will not accrue on any cash into which the
Debentures are convertible.

      (l) Whenever the Conversion Rate is adjusted as herein provided, the
Company shall promptly file with the Trustee and any conversion agent other than
the Trustee an Officers' Certificate setting forth the Conversion Rate after
such adjustment and setting forth a brief statement of the facts requiring such
adjustment. Unless and until a Responsible Officer of the Trustee shall have
received such Officers' Certificate, the Trustee shall not be deemed to have
knowledge of any adjustment of the Conversion Rate and may assume that the last
Conversion Rate of which it has knowledge is still in effect. Promptly after
delivery of such certificate, the Company shall prepare a notice of such
adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and
the date on which each adjustment becomes effective and shall mail, or cause the
Trustee to mail at the Company's expense, such notice of such adjustment of the
Conversion Rate to the holder of each Debenture at his last address appearing on
the Debenture Register provided for in Section 2.05 of this Indenture, within
twenty (20) days after execution thereof. Failure to deliver such notice shall
not affect the legality or validity of any such adjustment.

      (m) [Reserved.]

      (n) For purposes of this Section 17.05, 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.

      Section 17.06. Effect Of Reclassification, Consolidation, Merger or Sale.
If any of the following events occur, namely (i) any reclassification or change
of the outstanding shares of Common Stock (other than a change in par value, or
from par value to no par value, or from no par value to par value, or as a
result of a split, subdivision or combination), (ii) any consolidation, merger
or binding share exchange of the Company with another Person as a result of
which holders of Common Stock shall be entitled to receive stock, securities,
other property, assets or cash with respect to or in exchange for such Common
Stock, or (iii) any sale or conveyance of the properties and assets of the
Company as, or substantially as, an entirety to any other Person as a result of
which holders of Common Stock shall be entitled to receive stock, securities,
other property, assets or cash with respect to or in exchange for such Common
Stock, then:

      (a) the Company and each Subsidiary Guarantor (or the successor or
purchasing Person, as the case may be), shall execute with the Trustee a
supplemental indenture (which shall comply with the Trust Indenture Act as in
force at the date of execution of such supplemental indenture if such
supplemental indenture is then required to so comply) providing for the
conversion and

                                      102
<PAGE>

settlement of the Debentures as set forth in this Indenture. Such supplemental
indenture shall provide for adjustments which shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Article. If, in the
case of any such reclassification, change, consolidation, merger, binding share
exchange, sale or conveyance, the Exchange Property includes shares of stock,
other securities, property or assets of a Person other than the successor or
purchasing Person, as the case may be, in such reclassification, change,
consolidation, merger, binding share exchange, sale or conveyance, then such
supplemental indenture shall also be executed by such other Person and shall
contain such additional provisions to protect the interests of the holders of
the Debentures as the Board of Directors of the Company shall reasonably
consider necessary by reason of the foregoing, including to the extent required
by the Board of Directors of the Company and practicable the provisions
providing for the repurchase rights set forth in Article 3 herein.

      (b) Notwithstanding the provisions of Section 17.02(a), and subject to the
provisions of Section 17.01, the Conversion Value with respect to each $1,000
principal amount of Debentures tendered for conversion on or after the second
Trading Day immediately preceding the effective date of any such transaction,
shall be calculated (as provided in clause (d) below) based on the kind and
amount of stock, securities, other property, assets or cash received upon such
reclassification, change, consolidation, merger, binding share exchange, sale or
conveyance by a holder of Common Stock holding, immediately prior to the
transaction, a number of shares of Common Stock equal to the Conversion Rate
(plus Additional Shares, to the extent that the holder is entitled to Additional
Shares in accordance with Section 17.01(c) upon conversion) immediately prior to
such transaction (the "EXCHANGE PROPERTY"), assuming such holder of Common Stock
did not exercise his rights of election, if any, as to the kind or amount of
stock, securities, other property, assets or cash receivable upon such
consolidation, merger, binding share exchange, sale or conveyance (provided
that, if the kind or amount of stock, securities, other property, assets or cash
receivable upon such consolidation, merger, binding share exchange, sale or
conveyance is not the same for each share of Common Stock in respect of which
such rights of election shall not have been exercised ("NON-ELECTING SHARE"),
then for the purposes of this Section 17.06 the kind and amount of stock,
securities, other property, assets or cash receivable upon such consolidation,
merger, binding share exchange, sale or conveyance for 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).

      (c) The Conversion Value in respect of any Debentures tendered for
conversion on or after the second Trading Day immediately preceding the
effective date of any such transaction shall be equal to the average of the
daily values of the Exchange Property pertaining to such Debentures as
determined in the next sentence (the "EXCHANGE PROPERTY VALUE") for each of the
ten (10) consecutive Trading Days (appropriately adjusted to take into account
the occurrence during such period of stock splits and similar events) beginning
on the

                                      103
<PAGE>

later of (A) the second Trading Day immediately following the day the Debentures
are tendered for conversion and (B) the effective date of such transaction (the
"EXCHANGE PROPERTY AVERAGE PRICE"). For the purpose of determining the value of
any Exchange Property:

            (i) any shares of common stock of the successor or purchasing Person
      or any other Person that are included in the Exchange Property shall be
      valued as set forth in Section 17.02 as if such shares were "Common Stock"
      using the procedures set forth in the definition of "Closing Price" in
      Section 1.01; and

            (ii) any other securities, property or assets (other than cash)
      included in the Exchange Property shall be valued in good faith by the
      Board of Directors of the Company or by a New York Stock Exchange member
      firm selected by such Board of Directors.

      (d) The Company shall deliver such Conversion Value to holders of
Debentures so converted as follows:

            (i) An amount equal to the Principal Return, determined as set forth
      in Section 17.02(b)(i); and

            (ii) If the Conversion Value of the Debentures so converted is
      greater than the Principal Return, an amount of Exchange Property,
      determined as set forth below, equal to such aggregate Conversion Value
      less the Principal Return (the "NET EXCHANGE PROPERTY AMOUNT").

      The amount of Exchange Property to be delivered shall be determined by
dividing the Net Exchange Property Amount by the Exchange Property Average
Price. If the Exchange Property includes more than one kind of property, the
amount of Exchange Property of each kind to be delivered shall be in the
proportion that the Exchange Property Value of such kind of Exchange Property
bears to the Exchange Property Value of all the Exchange Property. If the
foregoing calculations would require the Company to deliver a fractional share
or unit of Exchange Property to a holder of Debentures being converted, the
Company shall deliver cash in lieu of such fractional share or unit based on its
Exchange Property Average Price.

      (e) Notwithstanding clauses (b), (c) and (d) above, if the Debentures are
tendered for conversion prior to the effective date of any such transaction
pursuant to Section 17.01(c) above, and the Principal Return and Net Shares, if
any, have been determined, but have not been delivered prior to the effective
date of such transaction, then the Company shall (i) pay the Principal Return in
cash and (ii) instead of delivering Net Shares, if applicable, deliver an amount
of Exchange Property that a holder of Common Stock, holding, immediately prior
to the transaction, a number of shares of Common Stock equal to the Net Shares,
would receive, assuming such holder of Common Stock did not exercise his rights

                                      104
<PAGE>

of election, if any, as to the kind or amount of stock, securities, other
property, assets or cash receivable upon such consolidation, merger, binding
share exchange, sale or conveyance (provided that, if the kind or amount of
stock, securities, other property, assets or cash receivable upon such
consolidation, merger, binding share exchange, sale or conveyance is not the
same for each non-electing share, then for the purposes of this Section 17.06
the kind and amount of stock, securities, other property, assets or cash
receivable upon such consolidation, merger, binding share exchange, sale or
conveyance for 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). If the
foregoing calculations would require the Company to deliver a fractional share
or unit of Exchange Property to a holder of Debentures being converted, the
Company shall deliver cash in lieu of such fractional share or unit based on the
Exchange Property Value (as so determined).

      (f) Notwithstanding clauses (b), (c), (d) and (e) above, if Debentures are
tendered for conversion at a time when neither of the ten day weighted averaging
periods contemplated in clause (c) or clause (e) applies in full to the
determination of the Conversion Value, then the Conversion Value and the amount
of cash and Exchange Property comprising the Principal Return and the Net Shares
will be determined proportionally, with the weighted average amount relating to
the portion of the ten day period falling prior to the effective date being
valued as contemplated by clause (e) and with the weighted average amount
relating to the portion of that period falling on or after the effective date
being valued as contemplated by clause (c).

      (g) The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each holder of Debentures, at his address appearing on
the Debenture register provided for in this Indenture, within twenty (20) days
after execution thereof. Failure to deliver such notice shall not affect the
legality or validity of such supplemental indenture.

      (h) The above provisions of this Section shall similarly apply to
successive reclassifications, changes, consolidations, mergers, binding share
exchanges, sales and conveyances.

      Section 17.07. Taxes On Shares Issued. The issue of any stock certificates
on conversions of Debentures shall be made without charge to the converting
Debentureholder for any documentary, stamp or similar issue or transfer tax in
respect of the issue thereof. The Company shall not, however, be required to pay
any such tax that may be payable in respect of any transfer involved in the
issue and delivery of stock, if any, in any name other than that of the holder
of any Debenture converted, and the Company shall not be required to issue or
deliver any such stock certificate unless and until the Person or Persons
requesting the issue thereof shall have paid to the Company the amount of such
tax or shall have established to the satisfaction of the Company that such tax
has been paid.

                                      105
<PAGE>

      Section 17.08. Reservation of Shares, Shares to Be Fully Paid; Compliance
With Governmental Requirements; Listing of Common Stock. The Company shall
provide, free from preemptive rights, out of its authorized but unissued shares
or shares held in treasury, sufficient shares of Common Stock to provide for the
conversion of the Debentures and payment of the Additional Shares, if any, from
time to time as such Debentures are presented for conversion or repurchase in
the case of a Additional Shares, if any.

      Before taking any action that would cause an adjustment increasing the
Conversion Rate to an amount that would cause the Conversion Price to be reduced
below the then par value, if any, of any shares of Common Stock that may be
issued upon conversion of the Debentures, the Company will take all corporate
action that may, in the opinion of its counsel, be necessary in order that the
Company may validly and legally issue shares of such Common Stock at such
adjusted Conversion Rate.

      The Company covenants that all shares of Common Stock that may be issued
upon conversion of Debentures will upon issue be fully paid and non-assessable
by the Company and free from all taxes, liens and charges with respect to the
issue thereof.

      The Company covenants that, if any shares of Common Stock to be provided
for the purpose of conversion of Debentures hereunder require registration with
or approval of any governmental authority under any federal or state law before
such shares may be validly issued upon conversion, the Company will in good
faith and as expeditiously as possible, to the extent then permitted by the
rules and interpretations of the Commission (or any successor thereto), endeavor
to secure such registration or approval, as the case may be.

      The Company further covenants that, if at any time the Common Stock shall
be listed on the New York Stock Exchange or any other national securities
exchange or automated quotation system, the Company will, if permitted by the
rules of such exchange or automated quotation system, list and keep listed, so
long as the Common Stock shall be so listed on such exchange or automated
quotation system, any Common Stock issuable upon conversion of the Debentures;
provided that if the rules of such exchange or automated quotation system permit
the Company to defer the listing of such Common Stock until the first conversion
of the Debentures in accordance with the provisions of this Indenture, the
Company covenants to list any Common Stock issuable upon conversion of the
Debentures in accordance with the requirements of such exchange or automated
quotation system at such time.

      Section 17.09. Responsibility Of Trustee. The Trustee and any other
conversion agent shall not at any time be under any duty or responsibility to
any holder of Debentures to determine the Conversion Rate or whether any facts
exist that may require any adjustment of the Conversion Rate, or with respect to
the nature or extent or calculation of any such adjustment when made, or with
respect

                                      106
<PAGE>

to the method employed, or herein or in any supplemental indenture provided to
be employed, in making the same. The Trustee and any other conversion agent
shall not be accountable with respect to the validity or value (or the kind or
amount) of any shares of Common Stock, or of any stock, securities, other
property, assets or cash that may at any time be issued or delivered upon the
conversion of any Debenture; and the Trustee and any other conversion agent make
no representations with respect thereto. Neither the Trustee nor any conversion
agent shall be responsible for any failure of the Company to issue, transfer or
deliver any shares of Common Stock or stock certificates or securities, other
property, assets or cash upon the surrender of any Debenture for the purpose of
conversion or to comply with any of the duties, responsibilities or covenants of
the Company contained in this Article 17. Without limiting the generality of the
foregoing, neither the Trustee nor any conversion agent shall be under any
responsibility to determine the correctness of any provisions contained in any
supplemental indenture entered into pursuant to Section 17.06 relating either to
the kind or amount of shares of stock or securities or property (including cash)
receivable by Debentureholders upon the conversion of their Debentures after any
event referred to in such Section 17.06 or to any adjustment to be made with
respect thereto, but, subject to the provisions of Section 9.01, may accept as
conclusive evidence of the correctness of any such provisions, and shall be
protected in relying upon, the Officers' Certificate (which the Company shall be
obligated to file with the Trustee prior to the execution of any such
supplemental indenture) with respect thereto.

      Section 17.10. Notice To Holders Prior To Certain Actions. In case:

      (a) the Company shall declare a dividend (or any other distribution) on
its Common Stock that would require an adjustment in the Conversion Rate
pursuant to Section 17.05; or

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

      (c) of any reclassification or reorganization of the Common Stock (other
than a subdivision or combination of its outstanding Common Stock, or a change
in par value, or from par value to no par value, or from no par value to par
value), or of any consolidation, merger or binding 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 conveyance 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;

                                      107
<PAGE>

the Company shall cause to be filed with the Trustee and to be mailed to each
holder of Debentures at his address appearing on the Debenture Register provided
for in Section 2.05 of this Indenture, as promptly as possible but in any event
at least ten (10) days prior to the applicable date hereinafter specified, a
notice stating (x) the date on which a record is to be taken for the purpose of
such dividend, distribution or 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 or rights are to be determined, or (y) the date
on which such reclassification, consolidation, merger, binding share exchange,
sale, conveyance, dissolution, liquidation or winding up is expected to become
effective or occur, and the date as of which it is expected that holders of
Common Stock of record shall be entitled to exchange their Common Stock for
securities or other property deliverable upon such reclassification,
consolidation, merger, binding share exchange, sale, conveyance, dissolution,
liquidation or winding up. Failure to give such notice, or any defect therein,
shall not affect the legality or validity of such dividend, distribution,
reclassification, consolidation, merger, binding share exchange, sale,
conveyance, dissolution, liquidation or winding up.

      Section 17.11. Stockholder Rights Plans. There shall be no adjustment to
the Conversion Rate upon the issuance of the rights (the "RIGHTS") provided for
in the Company's shareholder rights agreement dated November 18, 2003, as
amended, between the Company and Stock Trans, Inc., as amended, or in any future
rights plan adopted by the Company, prior to the Rights separating from the
Common Stock. If the Rights have separated from the shares of Common Stock in
accordance with the provisions of the applicable shareholder rights agreement so
that the holders of the Debentures would not be entitled to receive any rights
in respect of any Common Stock issuable upon conversion of the Debentures, the
Conversion Rate will be adjusted as if the Company distributed to all holders of
Common Stock shares of the Company's capital stock, evidences of indebtedness,
property or assets (including securities but excluding rights or warrants to
purchase Common Stock issued to all holders of Common Stock, Common Stock issued
as a dividend or distribution on Common Stock and cash distributions), subject
to readjustment in the event of the expiration, termination or redemption of the
rights.

      Section 17.12. Issuer Determination Final. Any determination that the
Company or Board of Directors of the Company must make pursuant to Section
17.01, Section 17.02, Section 17.03, Section 17.04, Section 17.05 or Section
17.06 shall, absent manifest error, be conclusive.

or permitted to be given or served by the Company may, at the Company's written
request received by the Trustee not fewer than five (5) Business Days prior (or
such shorter period of time as may be acceptable to the Trustee) to the date on
which such notice must be given or served, be given or served by the Trustee in
the name of and at the expense of the Company.

      The Trustee, by notice to the Company, may designate additional or

      Any notice or communication mailed to a Debentureholder shall be mailed to
him by first class mail, postage prepaid, at his address as it appears on the

      Section 18.04. Governing Law; Submission to Jurisdiction. This Indenture
and each Debenture shall be deemed to be a contract made under the laws of the

                                      109
<PAGE>

to conflicts of laws principles thereof. The parties to this Indenture each

of Interest on, Additional Amounts, if any, on, or principal of, the Debentures
or the redemption or repurchase date of any Debenture will not be a Business

      Section 18.07. Trust Indenture Act. This Indenture is hereby made subject
to, and shall be governed by, the provisions of the Trust Indenture Act required
to be part of and to govern indentures qualified under the Trust Indenture Act;
provided that unless otherwise required by law, notwithstanding the foregoing,
this Indenture and the Debentures issued hereunder shall not be subject to the
provisions of subsections (a)(1), (a)(2), and (a)(3) of Section 314 of the

                                      110
<PAGE>

Trust Indenture Act as now in effect or as hereafter amended or modified;
provided further that this Section 18.07 shall not require this Indenture or the
Trustee to be qualified under the Trust Indenture Act prior to the time such
qualification is in fact required under the terms of the Trust Indenture Act,
nor shall it constitute any admission or acknowledgment by any party to the
Indenture that any such qualification is required prior to the time such
qualification is in fact required under the terms of the Trust Indenture Act. If
any provision hereof limits, qualifies or conflicts with another provision
hereof that is required to be included in an indenture qualified under the Trust
Indenture Act, such required provision shall control.

      Section 18.08. No Security Interest Created. Nothing in this Indenture or
in the Debentures, expressed or implied, shall be construed to constitute a
security interest under the Uniform Commercial Code or similar legislation, as
now or hereafter enacted and in effect, in any jurisdiction in which property of
the Company or its subsidiaries is located.

      Section 18.09. Benefits Of Indenture. Nothing in this Indenture or in the
Debentures, express or implied, shall give to any Person, other than the parties
hereto, any paying agent, any authenticating agent, any Debenture Registrar and
their successors hereunder and the holders of Debentures any benefit or any
legal or equitable right, remedy or claim under this Indenture.

      Section 18.10. Authenticating Agent. The Trustee may appoint an
authenticating agent that shall be authorized to act on its behalf, and subject
to its direction, in the authentication and delivery of Debentures in connection
with the original issuance thereof and transfers and exchanges of Debentures
hereunder, including under Sections 2.04, 2.05, 2.06, 2.07, 3.03 and 3.05, as
fully to all intents and purposes as though the authenticating agent had been
expressly authorized by this Indenture and those Sections to authenticate and
deliver Debentures. For all purposes of this Indenture, the authentication and
delivery of Debentures by the authenticating agent shall be deemed to be
authentication and delivery of such Debentures "by the Trustee" and a
certificate of authentication executed on behalf of the Trustee by an
authenticating agent shall be deemed to satisfy any requirement hereunder or in
the Debentures for the Trustee's certificate of authentication. Such
authenticating agent shall at all times be a Person eligible to serve as trustee
hereunder pursuant to Section 9.09.

      Any corporation into which any authenticating agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any authenticating agent
shall be a party, or any corporation succeeding to the corporate trust business
of any authenticating agent, shall be the successor of the authenticating agent
hereunder, if such successor corporation is otherwise eligible under this
Section 18.10, without the execution or filing of any paper or any further act
on the part of the parties hereto or the authenticating agent or such successor
corporation.

                                      111
<PAGE>

      Any authenticating agent may at any time resign by giving written notice
of resignation to the Trustee and to the Company. The Trustee may at any time
terminate the agency of any authenticating agent by giving written notice of
termination to such authenticating agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee
shall either promptly appoint a successor authenticating agent or itself assume
the duties and obligations of the former authenticating agent under this
Indenture and, upon such appointment of a successor authenticating agent, if
made, shall give written notice of such appointment of a successor
authenticating agent to the Company and shall mail notice of such appointment of
a successor authenticating agent to all holders of Debentures as the names and
addresses of such holders appear on the Debenture Register.

      The Company agrees to pay to the authenticating agent from time to time
such reasonable compensation for its services as shall be agreed upon in writing
between the Company and the authenticating agent.

      The provisions of Sections 9.02, 9.03, 9.04 and 10.03 and this Section
18.10 shall be applicable to any authenticating agent.

      Section 18.11. Execution In Counterparts. This Indenture may be executed

in any manner the rights of the holders of the Debentures; provided that,
without the consent of the holders of all Debentures then Outstanding, no such

Amounts, if any, thereon, (c) reduce the principal amount thereof, (d) reduce

and Additional Amounts, if any, payable in any coin or currency other than that
provided in the Debentures, (k) impair the right of a holder to convert any
Debenture or reduce the amount of cash, the number of shares of Common Stock or

Subsidiary Guarantee or the Indenture other than in accordance with the terms of
the Indenture, (m) reduce the quorum or voting requirements set forth in Article
11 thereof, (n) modify any of the provisions of Section 12.02 or Section 8.07

provisions of the Indenture cannot be modified or waived without the consent of
the holder of each Debenture so affected or (o) reduce the aforesaid percentage
of Debentures, the holders of which are required to consent to any such
supplemental indenture.

      Notwithstanding the foregoing, with the consent of the holders of at least
25% in aggregate principal amount of the Debentures at the time Outstanding, the
Company and the Subsidiary Guarantors, when authorized by the resolutions of the
Board of Directors, and the Trustee may, from time to time and at any time,
enter into an indenture or indentures supplemental hereto for the purpose of
modifying Section 17.02 of the Indenture such that, from and after the date of
such modification or amendment, the Company shall have the ability to satisfy
the Principal Return upon conversion of a Debenture in cash, Common Stock or any
combination thereof; provided, however, that the Company may, without the
consent of the holders, (i) increase the percentage of such holders required to
approve the amendment or modification set forth in this paragraph or (ii)
eliminate the Company's right to implement any such amendment or modification.

      In addition, the provisions of Article 4 of the Indenture may not be
amended or modified in a manner adverse to the holders of the Debentures without
the consent of the holders of at least 75% in aggregate principal amount of the
Debentures then-Outstanding. Notwithstanding the foregoing, no amendment or
modification of the Indenture may occur that amends or modifies, or otherwise
adversely affects the rights of the holders of Senior Indebtedness under Article
4 of the Indenture without the prior written consent of the holders of such
Senior Indebtedness or the agent therefor acting on their behalf.

      Subject to the provisions of the Indenture, the holders of a majority in
aggregate principal amount of the Debentures at the time Outstanding may on
behalf of the holders of all of the Debentures waive any past default or Event
of Default under the Indenture and its consequences except (A) a default in the
payment of Interest and/or Additional Amounts, if any, on, or the principal of,
any of the Debentures, (B) a failure by the Company to convert any Debentures
pursuant to Article 17 of the Indenture, (C) a default in the payment of the

                                       A-8
<PAGE>

redemption price pursuant to Article 3 of the Indenture, (D) a default in the
payment of the repurchase price pursuant to Article 3 of the Indenture, (E) a
default in the delivery of the Additional Shares when due, or (F) a default in
respect of a covenant or provisions of the Indenture that under Article 12 of
the Indenture cannot be modified or amended without the consent of the holders
of each or all Debentures then Outstanding or affected thereby. Any such consent
or waiver by the holder of this Debenture (unless revoked as provided in the
Indenture) shall be conclusive and binding upon such holder and upon all future
holders and owners of this Debenture and any Debentures that may be issued in
exchange or substitution hereof, irrespective of whether or not any notation
thereof is made upon this Debenture or such other Debentures.

      The Debentures are subordinated to all Senior Indebtedness and are pari
passu in right of payment to all Senior Subordinated Indebtedness of the Company
and senior in right of payment to all Subordinated Indebtedness of the Company.
Each holder of this Debenture, whether upon original issue or upon registration
of transfer, assignment or exchange thereof, by accepting the same, agrees to
the subordination provisions set forth in Article 4 of the Indenture and
authorizes the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate the subordination so provided and appoints the Trustee
his attorney-in-fact for any and all such purposes.

      No reference herein to the subordination provisions of the Indenture and
no provision of this Debenture or of the Indenture shall alter or impair the
obligation of the Company, which is absolute and unconditional, to pay the
principal of, Interest on this Debenture and Additional Amounts, if any, at the
place, at the respective times, at the rate and in the coin or currency herein
prescribed.

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

      The Debentures are issuable in fully registered form, without coupons, in
denominations of $1,000 principal amount and any integral multiple of $1,000. At
the office or agency of the Company referred to on the face hereof, and in the
manner and subject to the limitations provided in the Indenture, without payment
of any service charge but with payment of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in connection with
any registration or exchange of Debentures, Debentures may be exchanged for a
like aggregate principal amount of Debentures of any other authorized
denominations.

      The Company may not redeem any Debentures before March 20, 2010. On or
after March 20, 2010 but prior to March 15, 2012, the Company shall have the
option to redeem some or all of the Debentures at any time or from time to

                                       A-9
<PAGE>

time but only if the Closing Price of the Common Stock for twenty (20) Trading
Days within a period of thirty (30) consecutive Trading Days ending on the
Trading Day before the Company provides the notice required by Section 3.02 of
the Indenture exceeds 130% of the Conversion Price in effect on each such
Trading Day, subject to adjustment as provided in Section 17.05 of the
Indenture. At any time on or after March 15, 2012 and prior to maturity, the
Debentures may be redeemed at any time or from time to time at the option of the
Company, in whole or in part. The Company may redeem the Debentures upon mailing
a notice of such redemption not less than thirty (30) days but not more than
sixty (60) days before the redemption date to the holders of Debentures at their
last registered addresses, all as provided in the Indenture, at a redemption
price equal to 100% of the principal amount of Debentures being redeemed and
accrued and unpaid Interest, and Additional Amounts, if any, to, but excluding,
the redemption date; provided that if the redemption date falls after a Record
Date and on or prior to the corresponding Interest Payment Date, then the
Interest and Additional Amounts, if any, payable on such date shall be paid to
the holder of record at the close of business on the corresponding Record Date.
The Debentures will be redeemable in integral multiples of $1,000 principal
amount.

      The Company may not give notice of any redemption of the Debentures if a
default in the payment of Interest and/or Additional Amounts, if any, on the
Debentures has occurred and is continuing.

      The Debentures are not subject to redemption through the operation of any
sinking fund.

      If a Designated Event occurs at any time prior to maturity of the
Debentures, the Debentures may be repurchased for cash at the option of the
holders of the Debentures on a Designated Event Repurchase Date, not less than
twenty (20) nor more than thirty-five (35) Business Days after notice thereof,
at the option of the holder of this Debenture at a redemption price equal to
100% of the principal amount thereof, together with accrued and unpaid Interest
and Additional Amounts, if any, to (but excluding) the Designated Event
Repurchase Date; provided that if such Designated Event Repurchase Date falls
after a Record Date and on or prior the corresponding Interest Payment Date, the
Interest and Additional Amounts, if any, payable on such Interest Payment Date
shall be paid to the holder of record of this Debenture at the close of business
on the corresponding Record Date. The Company shall mail, or cause the Trustee
to mail, to all holders of record of the Debentures a notice of the occurrence
of a Designated Event and of the repurchase right arising as a result thereof on
or before the 20th day after the occurrence of such Designated Event. For a
Debenture to be so repurchased at the option of the holder, the Company must
receive at the office or agency of the Company maintained for that purpose in
accordance with the terms of the Indenture, such Debenture with the form
entitled "OPTION TO ELECT REPURCHASE UPON A DESIGNATED EVENT" on the reverse
thereof

                                      A-10
<PAGE>

duly completed, together with such Debenture, duly endorsed for transfer, on or
before the Designated Event Expiration Time.

      Subject to the terms and conditions of the Indenture, the Company shall
become obligated to purchase in cash, at the option of the holder, all or any
portion of the Debentures held by such holder on March 15, 2012, March 15, 2015
and March 15, 2020 in whole multiples of $1,000 at a purchase price of 100% of
the principal amount, plus any accrued and unpaid Interest and Additional
Amounts, if any, on such Debenture to but excluding the Repurchase Date;
provided that if such Repurchase Date falls after a Record Date and on or prior
the corresponding Interest Payment Date, the Interest and Additional Amounts, if
any, payable on such Interest Payment Date shall be paid to the holder of record
of this Debenture at the close of business on the corresponding Record Date. To
exercise such right, a holder shall deliver to the Company such Debenture with
the form entitled "REPURCHASE NOTICE" on the reverse thereof duly completed,
together with the Debenture, duly endorsed for transfer, at any time from the
opening of business on the date that is twenty (20) Business Days prior to such
Repurchase Date until the close of business on the Repurchase Date, and shall
deliver the Debentures to the Trustee (or other paying agent appointed by the
Company) as set forth in the Indenture.

      Holders have the right to withdraw any Option to Elect Repurchase Upon a
Designated Event or Repurchase Notice, as the case may be, by delivering to the
Trustee (or other paying agent appointed by the Company) a written notice of
withdrawal up to the close of business on the Designated Event Repurchase Date
or Repurchase Date, as the case may be, all as provided in the Indenture.

      If cash sufficient to pay the purchase price of all Debentures or portions
thereof to be purchased as of the Designated Event Repurchase Date or Repurchase
Date, as the case may be, is held by the Trustee (or other paying agent
appointed by the Company), on the Business Day following the Designated Event
Repurchase Date or Repurchase Date, as the case may be, the Debentures will
cease to be Outstanding, Interest and Additional Amounts, if any, will cease to
accrue on such Debentures (or portions thereof) and all other rights of the
holder of such Debentures will terminate, other than the right to receive the
repurchase price upon surrender of such Debenture.

      Subject to the occurrence of certain events and in compliance with the
provisions of the Indenture, prior to the close of business on the Business Day
immediately preceding March 15, 2025, the holder hereof has the right, at its
option, to convert each $1,000 principal amount of the Debentures into cash and
shares of Common Stock, if any, at a conversion rate equivalent to 18.4493 (the
"CONVERSION RATE") (a conversion price of approximately $54.2025 per share),
subject to adjustment from time to time as provided in the Indenture, upon
surrender of this Debenture with the form entitled "CONVERSION NOTICE" on the

                                      A-11
<PAGE>

reverse hereof duly completed, to the Company at the office or agency of the
Company maintained for that purpose in accordance with the terms of the
Indenture, or at the option of such holder, the Corporate Trust Office, and,
unless any shares issuable on conversion are to be issued in the same name as
this Debenture, duly endorsed by, or accompanied by instruments of transfer in
form satisfactory to the Company duly executed by, the holder or by his duly
authorized attorney. If on any Conversion Date, the Company is required to pay
Additional Amounts pursuant to the Registration Rights Agreement, the Conversion
Rate on such date will be multiplied by 1.03. The Company will notify the holder
thereof of any event triggering the right to convert the Debentures as specified
above in accordance with the Indenture.

      No adjustment in respect of Interest or Additional Amounts, if any, on any
Debenture converted or dividends on any shares issued upon conversion of such
Debenture will be made upon any conversion except as set forth in the next
sentence. If this Debenture (or portion hereof) is surrendered for conversion
during the period from the close of business on any Record Date for the payment
of Interest and Additional Amounts, if any, to the close of business on the
Business Day preceding the following Interest Payment Date, this Debenture (or
portion hereof being converted) must be accompanied by payment, in immediately
available funds or other funds acceptable to the Company, of an amount equal to
the Interest and Additional Amounts, if any, otherwise payable on such Interest
Payment Date on the principal amount being converted; provided that no such
payment shall be required (1) if the Company has specified a redemption date
that is after a Record Date and on or prior to the next Interest Payment Date,
(2) if the Company has specified a Designated Event Repurchase Date that is
during such period or (3) to the extent of any overdue Interest or Additional
Amounts, if any, if any overdue Interest or Additional Amounts exist at the time
of conversion with respect to such Debenture.

      No fractional shares will be issued upon any conversion, but a payment in
cash will be made, as provided in the Indenture, in respect of any fraction of a
share which would otherwise be issuable upon the surrender of any Debenture or
Debentures for conversion.

      A Debenture in respect of which a holder is exercising its right to
require repurchase upon a Designated Event or repurchase on a Repurchase Date
may be converted only if such holder withdraws its election to exercise either
such right in accordance with the terms of the Indenture.

      Upon due presentment for registration of transfer of this Debenture at the
office or agency of the Company maintained for that purpose in accordance with
the terms of the Indenture, a new Debenture or Debentures of authorized
denominations for an equal aggregate principal amount will be issued to the
transferee in exchange therefor, subject to the limitations provided in the

                                      A-12
<PAGE>

Indenture, without charge except for any tax, assessment or other governmental
charge imposed in connection therewith.

      The Company, the Trustee, any authenticating agent, any paying agent, any
conversion agent and any Debenture Registrar may deem and treat the registered
holder hereof as the absolute owner of this Debenture (whether or not this
Debenture shall be overdue and notwithstanding any notation of ownership or
other writing hereon made by anyone other than the Company or any Debenture
Registrar) for the purpose of receiving payment hereof, or on account hereof,
for the conversion hereof and for all other purposes, and neither the Company
nor the Trustee nor any other authenticating agent nor any paying agent nor
other conversion agent nor any Debenture Registrar shall be affected by any
notice to the contrary. All payments made to or upon the order of such
registered holder shall, to the extent of the sum or sums paid, satisfy and
discharge liability for monies payable on this Debenture.

      No recourse for the payment of the principal of or Interest and Additional
Amounts, if any, on this Debenture, or for any claim based hereon or otherwise
in respect hereof, and no recourse under or upon any obligation, covenant or
agreement of the Company in the Indenture or any supplemental indenture or in
any Debenture, or because of the creation of any indebtedness represented
thereby, shall be had against any incorporator, stockholder, employee, agent,
officer, director or Subsidiary, as such, past, present or future, of the
Company or of any successor corporation, either directly or through the Company
or any successor corporation, whether by virtue of any constitution, statute or
rule of law or by the enforcement of any assessment or penalty or otherwise, all
such liability being, by acceptance hereof and as part of the consideration for
the issue hereof, expressly waived and released.

      Terms used in this Debenture and defined in the Indenture are used herein
as therein defined.
