          (2) The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange or automated quotation system on which the Notes 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 2.4 EXECUTION OF NOTES. The Notes 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") and attested by the manual or facsimile
signature of its Secretary or any of its Assistant Secretaries or its Treasurer
or any of its Assistant Treasurers (which may be printed, engraved or otherwise
reproduced thereon, by facsimile or otherwise). Only such Notes as shall bear
thereon a certificate of authentication substantially in the form set forth on
the form of Note attached as Exhibit A hereto, manually executed by the Trustee
(or an authenticating agent appointed by the Trustee as provided by Section
16.11), 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 Note executed by the Company shall be conclusive
evidence that the Note 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 who shall have signed any of the
Notes shall cease to be such officer before the Notes so signed shall have been
authenticated and delivered by the Trustee, or disposed of by the Company, such
Notes nevertheless may be authenticated and delivered or disposed of as though
the person who signed such Notes had not ceased to be such officer of the
Company, and any Note may be signed on behalf of the Company by such persons as,
at the actual date of the execution of such Note, shall be the proper officers
of the Company, although at the date of the execution of this Indenture any such
person was not such an officer.

          Section 2.5 EXCHANGE AND REGISTRATION OF TRANSFER OF NOTES;
RESTRICTIONS ON TRANSFER; DEPOSITARY.

          (a) The Company shall cause to be kept at the Corporate Trust Office a
register (the register maintained in such office and in any other office or
agency of the Company designated pursuant to Section 5.2 being herein sometimes
collectively referred to as the "Note register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Notes and of transfers of Notes. The Note register shall be in
written form or in any form capable of being converted into written form within
a reasonably prompt period of time. The Trustee is hereby appointed "Note
registrar" for the purpose of registering Notes and transfers of Notes as herein
provided. The Company may appoint one or more co-registrars in accordance with
Section 5.2.

          Upon surrender for registration of transfer of any Note to the Note
registrar or any co-registrar, and satisfaction of the requirements for such
transfer set forth in this Section 2.5, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Notes of any authorized denominations and of a
like aggregate principal amount and bearing such restrictive legends as may be
required by this Indenture.

          Notes may be exchanged for other Notes of any authorized denominations
and of a like aggregate principal amount, upon surrender of the Notes to be
exchanged at any such office or agency maintained by the Company pursuant to
Section 5.2. Whenever any Notes are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Notes which
the Noteholder making the exchange is entitled to receive bearing registration
numbers not contemporaneously outstanding.

          All Notes issued upon any registration of transfer or exchange of
Notes shall be the valid obligations of the Company, evidencing the same debt,
and entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

          All Notes presented or surrendered for registration of transfer or for
exchange, redemption or conversion shall (if so required by the Company or the
Note registrar) be duly endorsed, or be accompanied by a written

                                       17
<PAGE>

instrument or instruments of transfer in form satisfactory to the Company, and
the Notes shall be duly executed by the Noteholder thereof or his attorney duly
authorized in writing.

          No service charge shall be made for any registration of transfer or
exchange of Notes, but the Company may require payment 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 Notes.

          Neither the Company nor the Trustee nor any Note registrar shall be
required to exchange or register a transfer of (a) any Notes for a period of
fifteen (15) days next preceding any selection of Notes to be redeemed, (b) any
Notes or portions thereof called for redemption pursuant to Section 3.2, (c) any
Notes or portions thereof surrendered for conversion pursuant to Article Fifteen
or (d) any Notes or portions thereof tendered for redemption (and not withdrawn)
pursuant to Section 3.5.

          (b) So long as the Notes are eligible for book-entry settlement with
the Depositary, or unless otherwise required by law, all Notes that, upon
initial issuance are beneficially owned by QIBs or as a result of a sale or
transfer after initial issuance are beneficially owned by QIBs, will be
represented by one or more Notes in global form registered in the name of the
Depositary or the nominee of the Depositary (the "Global Note"), except as
otherwise specified below. The transfer and exchange of beneficial interests in
any such Global Note shall be effected through the Depositary in accordance with
this Indenture and the procedures of the Depositary therefor. The Trustee shall
make appropriate endorsements to reflect increases or decreases in the principal
amounts of any such Global Note as set forth on the face of the Note ("Principal
Amount") to reflect any such transfers. Except as provided below, beneficial
owners of a Global Note shall not be entitled to have certificates registered in
their names, will not receive or be entitled to receive physical delivery of
certificates in definitive form and will not be considered holders of such
Global Note.

          (c) So long as the Notes are eligible for book-entry settlement with
the Depositary, or unless otherwise required by law, upon any transfer of a
definitive Note to a QIB in accordance with Rule 144A, and upon receipt of the

                                       18
<PAGE>

definitive Note or Notes being so transferred, together with a certification,
substantially in the form on the reverse of the Note, from the transferor that
the transfer is being made in compliance with Rule 144A (or other evidence
satisfactory to the Trustee), the Trustee shall make an endorsement on the
Global Note to reflect an increase in the aggregate Principal Amount of the
Notes represented by such Global Note, and the Trustee shall cancel such
definitive Note or Notes in accordance with the standing instructions and
procedures of the Depositary, the aggregate Principal Amount of the Notes
represented by such Global Note to be increased accordingly; provided, however,
that no definitive Note, or portion thereof, in respect of which the Company or
an Affiliate of the Company held any beneficial interest shall be included in
such Global Note until such definitive Note is freely tradable in accordance
with Rule 144(k) under the Securities Act, provided further that the Trustee
shall issue Notes in definitive form upon any transfer of a beneficial interest
in the Global Note to the Company or any Affiliate of the Company.

          Upon any sale or transfer of a Note to an Institutional Accredited
Investor (other than pursuant to a registration statement that has been declared
effective under the Securities Act), such Institutional Accredited Investor
shall, prior to such sale or transfer, furnish to the Company and/or the Trustee
a signed letter containing representations and agreements relating to
restrictions on transfer substantially in the form set forth in Exhibit B to
this Indenture. Upon any transfer of a beneficial interest in the Global Note to
an Institutional Accredited Investor, the Trustee shall make an endorsement on
the Global Note to reflect a decrease in the aggregate Principal Amount of the
Notes represented by such Global Note, and the Company shall execute a
definitive Note or Notes in exchange therefore, and the Trustee, upon receipt of
such definitive Note or Notes and the written order of the Company, shall
authenticate and deliver such, definitive Note or Notes.

          Any Note in global form may be endorsed with or have incorporated in
the text thereof such legends or recitals or changes not inconsistent with the
provisions of this Indenture as may be required by the Custodian, the Depositary
or by the National Association of Securities Dealers, Inc. in order for the
Notes to be tradeable on The Portal Market or as may be required for the Notes
to be tradeable on any other market developed for trading of securities pursuant
to Rule 144A or required to comply with

                                       19
<PAGE>

any applicable law or any regulation thereunder or with the rules and
regulations of any securities exchange or automated quotation system upon which
the Notes may be listed or traded or to conform with any usage with respect
thereto, or to indicate any special limitations or restrictions to which any
particular Notes are subject.

          (d) Every Note that bears or is required under this Section 2.5(d) to
bear the legend set forth in this Section 2.5(d) (together with any Common Stock
issued upon conversion of the Notes and required to bear the legend set forth in
Section 2.5(e), collectively, the "Restricted Securities") shall be subject to
the restrictions on transfer set forth in this Section 2.5(d) (including those
set forth in the legend set forth 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 Noteholder's acceptance thereof, agrees to be bound
by all such restrictions on transfer. As used in Sections 2.5(d) and 2.5(e), the
term "transfer" encompasses any sale, pledge, loan, transfer or other
disposition whatsoever of any Restricted Security.

          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 Note (and all securities issued in exchange therefor
or substitution thereof, other than Common Stock, if any, issued upon conversion
thereof, which shall bear the legend set forth in Section 2.5(e), if applicable)
shall bear a legend in substantially the following form, unless such Note has
been sold pursuant to a registration statement that has been declared effective
under the Securities Act (and which continues to be effective at the time of
such transfer), or unless otherwise agreed by the Company in writing, with
written notice thereof to the Trustee:

         THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE UNITED
         STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
         ANY STATE SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD
         WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S.
         PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS
         ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A
         "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE
         SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL "ACCREDITED INVESTOR"

                                       20
<PAGE>

         (AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7) UNDER THE SECURITIES
         ACT) ("INSTITUTIONAL ACCREDITED INVESTOR"); (2) AGREES THAT IT WILL
         NOT, PRIOR TO EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF
         THE NOTE EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT
         (OR ANY SUCCESSOR PROVISION), RESELL OR OTHERWISE TRANSFER THE NOTE
         EVIDENCED HEREBY OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH
         NOTE EXCEPT (A) TO CONEXANT SYSTEMS, INC. OR ANY SUBSIDIARY THEREOF,
         (B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A
         UNDER THE SECURITIES ACT, (C) TO AN INSTITUTIONAL ACCREDITED INVESTOR
         THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO BANK ONE TRUST COMPANY,
         NATIONAL ASSOCIATION, AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS
         APPLICABLE), A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
         AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THE NOTE
         EVIDENCED HEREBY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH
         TRUSTEE OR A SUCCESSOR TRUSTEE, AS APPLICABLE), (D) PURSUANT TO THE
         EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES
         ACT (IF AVAILABLE) OR (E) PURSUANT TO A REGISTRATION STATEMENT WHICH
         HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH
         CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); (3) PRIOR TO
         SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE (2)(E) ABOVE),
         IT WILL FURNISH TO BANK ONE TRUST COMPANY, NATIONAL ASSOCIATION, AS
         TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS,
         LEGAL OPINIONS OR OTHER INFORMATION AS THE TRUSTEE MAY REASONABLY
         REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
         EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
         REQUIREMENTS OF THE SECURITIES ACT; AND (4) AGREES THAT IT WILL DELIVER
         TO EACH PERSON TO WHOM THE NOTE EVIDENCED HEREBY IS TRANSFERRED A
         NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH
         ANY TRANSFER OF THE NOTE EVIDENCED HEREBY PRIOR TO THE EXPIRATION OF
         THE HOLDING PERIOD APPLICABLE TO SALES OF THE NOTE EVIDENCED HEREBY
         UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR
         PROVISION), THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE
         REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS
         CERTIFICATE TO BANK ONE TRUST COMPANY, NATIONAL ASSOCIATION, AS TRUSTEE

                                       21
<PAGE>

         (OR A SUCCESSOR TRUSTEE, AS APPLICABLE). IF THE PROPOSED TRANSFEREE IS
         AN INSTITUTIONAL ACCREDITED INVESTOR OR IS A PURCHASER WHO IS NOT A
         U.S. PERSON, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO BANK
         ONE TRUST COMPANY, NATIONAL ASSOCIATION, AS TRUSTEE (OR A SUCCESSOR
         TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER
         INFORMATION AS SUCH TRUSTEE MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH
         TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A
         TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
         SECURITIES ACT. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE
         TRANSFER OF THE NOTE EVIDENCED HEREBY PURSUANT TO CLAUSE (2)(E) ABOVE
         OR UPON ANY TRANSFER OF THE NOTE EVIDENCED HEREBY UNDER RULE 144(K)
         UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION). AS USED HEREIN,
         THE TERMS "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO
         THEM BY REGULATION S UNDER THE SECURITIES ACT.

          Any Note (or security issued in exchange or substitution therefor) 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 Note for exchange to the
Note registrar in accordance with the provisions of this Section 2.5, be
exchanged for a new Note or Notes, of like tenor and aggregate principal amount,
which shall not bear the restrictive legend required by this Section 2.5(d).

          Notwithstanding any other provisions of this Indenture (other than the
provisions set forth in the second paragraph of Section 2.5(c) and in this
Section 2.5(d)), a Note in global form may not be transferred as a whole or in
part except by the Depositary to a nominee of the Depositary or by a nominee of
the Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such
successor Depositary.

          The Depositary shall be a clearing agency registered under the
Exchange Act. The Company initially appoints The Depository Trust Company to act
as Depositary with respect to the Notes in global form. Initially, the Global
Note shall be issued to the Depositary, registered in

                                       22
<PAGE>

the name of Cede & Co., as the nominee of the Depositary, and deposited with the
Custodian for Cede & Co.

          If at any time the Depositary for a Note in global form notifies the
Company that it is unwilling or unable to continue as Depositary for such Note,
the Company may appoint a successor Depositary with respect to such Note. If a
successor Depositary is not appointed by the Company within ninety (90) days
after the Company receives such notice, the Company will execute, and the
Trustee, upon receipt of an Officers' Certificate for the authentication and
delivery of Notes, will authenticate and deliver, Notes in certificated form, in
aggregate principal amount equal to the principal amount of such Note in global
form, in exchange for such Note in global form.

          If a Note in certificated form is issued in exchange for any portion
of a Note in global form after the close of business at the office or agency
where such exchange occurs on any record date and before the opening of business
at such office or agency on the next succeeding interest payment date, interest
will not be payable on such interest payment date in respect of such
certificated Note, but will be payable on such interest payment date, subject to
the provisions of Section 2.3, only to the Person to whom interest in respect of
such portion of such Note in global form is payable in accordance with the
provisions of this Indenture.

          Notes in certificated form issued in exchange for all or a part of a
Note in global form pursuant to this Section 2.5 shall be registered in such
names and in such authorized denominations as the Depositary, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. Upon execution and authentication, the Trustee shall
deliver such Notes in certificated form to the Persons in whose names such Notes
in certificated form are so registered.

          At such time as all interests in a Note in global form have been
redeemed, converted, canceled, exchanged for Notes in certificated form, or
transferred to a transferee who receives Notes in certificated form thereof,
such Note in global form shall, upon receipt thereof, be canceled 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 Note in global form is exchanged for Notes in

                                       23
<PAGE>

certificated form, redeemed, converted, repurchased or canceled, or transferred
to a transferee who receives Notes in certificated form therefor or any Note in
certificated form is exchanged or transferred for part of a Note in global form,
the principal amount of such Note in global form shall, in accordance with the
standing procedures and instructions existing between the Depositary and the
Custodian, be appropriately reduced or increased, as the case may be, and an
endorsement shall be made on such Note in global form, by the Trustee or the
Custodian, at the direction of the Trustee, to reflect such reduction or
increase.

          (e) Until the expiration of the holding period applicable to sales
thereof under Rule 144(k) under the Securities Act (or any successor provision),
any stock certificate representing Common Stock issued upon conversion of any
Note shall bear a legend in substantially the following form, unless such Common
Stock has been sold pursuant to a registration statement that has been declared
effective under the Securities Act (and which continues to be effective at the
time of such transfer) or such Common Stock has been issued upon conversion of
Notes that have been transferred pursuant to a registration statement that has
been declared effective under the Securities Act, or unless otherwise agreed by
the Company in writing with written notice thereof to the transfer agent:

         THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE
         UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
         ACT"), OR ANY STATE SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE
         OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR
         BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE.
         THE HOLDER HEREOF AGREES THAT, UNTIL THE EXPIRATION OF THE HOLDING
         PERIOD APPLICABLE TO SALES OF THE COMMON STOCK EVIDENCED HEREBY UNDER
         RULE 144(K) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION), (1)
         IT WILL NOT RESELL OR OTHERWISE TRANSFER THE COMMON STOCK EVIDENCED
         HEREBY EXCEPT (A) TO CONEXANT SYSTEMS, INC. OR ANY SUBSIDIARY THEREOF,
         (B) TO A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER
         THE SECURITIES ACT) IN COMPLIANCE WITH RULE 144A, (C) TO AN
         INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1), (2),
         (3) OR (7) UNDER THE SECURITIES ACT) THAT PRIOR TO

                                       24
<PAGE>

         SUCH TRANSFER, FURNISHES TO CHASEMELLON SHAREHOLDER SERVICES, L.L.C.,
         AS TRANSFER AGENT (OR A SUCCESSOR TRANSFER AGENT, AS APPLICABLE), A
         SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS
         RELATING TO THE RESTRICTIONS ON TRANSFER OF THE COMMON STOCK EVIDENCED
         HEREBY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH TRANSFER
         AGENT OR A SUCCESSOR TRANSFER AGENT, AS APPLICABLE), (D) PURSUANT TO
         THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
         SECURITIES ACT (IF AVAILABLE), OR (E) PURSUANT TO A REGISTRATION
         STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT
         (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); (2)
         PRIOR TO SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE (1)(E)
         ABOVE), IT WILL FURNISH TO CHASEMELLON SHAREHOLDER SERVICES, L.L.C., AS
         TRANSFER AGENT (OR A SUCCESSOR TRANSFER AGENT, AS APPLICABLE), SUCH
         CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS SUCH TRANSFER
         AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING
         MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO,
         THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (3) IT WILL
         DELIVER TO EACH PERSON TO WHOM THE COMMON STOCK EVIDENCED HEREBY IS
         TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 1(E) ABOVE) A
         NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IF THE PROPOSED
         TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR OR IS A PURCHASER
         WHO IS NOT A U.S. PERSON, THE HOLDER MUST, PRIOR TO SUCH TRANSFER,
         FURNISH TO CHASEMELLON SHAREHOLDER SERVICES, L.L.C. (OR A SUCCESSOR
         TRANSFER AGENT, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR
         OTHER INFORMATION AS IT MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH
         TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A
         TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
         SECURITIES ACT. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE
         TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY PURSUANT TO CLAUSE (1)(E)
         ABOVE OR UPON ANY TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY AFTER
         THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE
         SECURITY EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT
         (OR ANY SUCCESSOR PROVISION). AS USED HEREIN, THE TERMS "UNITED STATES"
         AND "U.S. PERSON" HAVE THE

                                       25
<PAGE>

         MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

          Any such Common Stock as to which such restrictions on transfer shall
have expired in accordance with their terms or as to which the conditions for
removal of the foregoing legend set forth therein have been satisfied may, upon
surrender of the certificates representing such shares of Common Stock for
exchange in accordance with the procedures of the transfer agent for the Common
Stock, be exchanged for a new certificate or certificates for a like number of
shares of Common Stock, which shall not bear the restrictive legend required by
this Section 2.5(e).

          (f) Any Note or Common Stock issued upon the conversion or exchange of
a Note 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 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 which results in such Notes or Common Stock, as
the case may be, no longer being "restricted securities" (as defined under Rule
144).

          Section 2.6 MUTILATED, DESTROYED, LOST OR STOLEN NOTES. In case any
Note shall become mutilated or be destroyed, lost or stolen, the Company in its
discretion may execute, and upon its written request the Trustee or an
authenticating agent appointed by the Trustee shall authenticate and make
available for delivery, a new Note, bearing a number not contemporaneously
outstanding, in exchange and substitution for the mutilated Note, or in lieu of
and in substitution for the Note so destroyed, lost or stolen. In every case the
applicant for a substituted Note 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 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 Note
and of the ownership thereof.

                                       26
<PAGE>

          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 Note and make available for delivery such
Note. Upon the issuance of any substituted Note, the Company may require the
payment 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 Note which has matured or is about to mature or has been
called for redemption or has been tendered for redemption (and not withdrawn) or
is to be converted into Common Stock shall become mutilated or be destroyed,
lost or stolen, the Company may, instead of issuing a substitute Note, 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 Note), 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 connected 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 Note and of the ownership thereof.

          Every substitute Note issued pursuant to the provisions of this
Section 2.6 by virtue of the fact that any Note is destroyed, lost or stolen
shall constitute an additional contractual obligation of the Company, whether or
not the destroyed, lost or stolen Note 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
Notes duly issued hereunder. To the extent permitted by law, all Notes shall be
held and owned upon the express condition that the foregoing provisions are
exclusive with respect to the replacement or payment or conversion of mutilated,
destroyed, lost or stolen Notes 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 of negotiable
instruments or other securities without their surrender.

          Section 2.7 TEMPORARY NOTES. Pending the preparation of Notes in
certificated form, the Company may execute and the Trustee or an authenticating
agent appointed by the Trustee shall, upon the written request of the Company,
authenticate and deliver temporary Notes (printed or lithographed). Temporary
Notes shall be issuable in any authorized denomination, and substantially in the
form of the Notes in certificated form, but with such omissions, insertions and
variations as may be appropriate for temporary Notes, all as may be determined
by the Company. Every such temporary Note 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 Notes in certificated form. Without unreasonable delay the Company will
execute and deliver to the Trustee or such authenticating agent Notes in
certificated form (other than in the case of Notes in global form) and thereupon
any or all temporary Notes (other than any such Note in global form) may be
surrendered in exchange therefor, at each office or agency maintained by the
Company pursuant to Section 5.2 and the Trustee or such authenticating agent
shall authenticate and make available for delivery in exchange for such
temporary Notes an equal aggregate principal amount of Notes 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 Notes shall in all
respects be entitled to the same benefits and subject to the same limitations
under this Indenture as Notes in certificated form authenticated and delivered
hereunder.

          Section 2.8 CANCELLATION OF NOTES PAID, ETC. All Notes surrendered for
the purpose of payment, redemption, conversion, exchange or registration of
transfer shall, if surrendered to the Company or any paying agent or any Note
registrar or any conversion agent, be surrendered to the Trustee and promptly
canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by
it, and no Notes shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Indenture. The Trustee shall dispose of such
canceled Notes in accordance with its customary procedures. If the Company shall
acquire any of the Notes, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Notes unless and until the
same are delivered to the Trustee for cancellation.

          Section 2.9 CUSIP NUMBERS. The Company in issuing the Notes 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 Noteholders;
provided, however, that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Notes or as
contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Notes, 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 THREE

                               REDEMPTION OF NOTES

          Section 3.1 (a) INITIAL PROHIBITION ON REDEMPTION. Except as otherwise
provided in Section 3.5, the Notes may not be redeemed by the Company, in whole
or in part, at any time prior to February 6, 2003.

          (b) OPTIONAL REDEMPTION BY THE COMPANY. At any time on or after
February 6, 2003, and prior to maturity, the Notes may be redeemed at the option
of the Company (an "Optional Redemption"), in whole or in part, upon notice as
set forth in Section 3.2 (the "Notice Date"), at the following Optional
Redemption prices (expressed as percentages of the principal amount), together
in each case with accrued and unpaid interest, if any (including Liquidated
Damages, if any) to, but excluding, the date fixed for redemption:

Period                                                  Redemption Price
------                                                  ----------------

Beginning on February 6, 2003 and ending on                 102.286%
January 31, 2004

Beginning on February 1, 2004 and ending on                 101.714%

                                       29
<PAGE>

and 100% on February 1, 2007; provided, however, that if the date fixed for
redemption is on a February 1 or August 1, then the interest payable on such
date shall be paid to the holder of record on the preceding January 15 or July
15, respectively.

          Section 3.2 NOTICE OF REDEMPTIONS; SELECTION OF NOTES. In case the
Company shall desire to exercise the right to redeem all or, as the case may be,
any part of the Notes pursuant to Section 3.1, it shall fix a date for
redemption and it or, at its written request 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 date fixed for redemption to the holders of Notes so to be
redeemed as a whole or in part at their last addresses as the same appear on the
Note register; provided, however, that if the Company shall give such notice, it
shall also give written notice, and written notice of the Notes to be redeemed,
to the Trustee. The Company may not give notice of any redemption of the Notes
if a default in payment of interest or premium, if any, on the Notes has
occurred and is continuing. 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 Note designated for redemption as a whole or in part shall not
affect the validity of the proceedings for the redemption of any other Note.
Concurrently with 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 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 Note called for redemption.

          Each such notice of redemption shall specify the aggregate principal
amount of Notes to be redeemed, the CUSIP number or numbers of the Notes being
redeemed, the date fixed for redemption (which shall be a Business Day), the
redemption price at which Notes are to be redeemed, the place or places of
payment, that payment will be made upon

                                       30
<PAGE>

presentation and surrender of such Notes, that interest accrued to the date
fixed for redemption will be paid as specified in said notice, and that on and
after said date interest thereon or on the portion thereof to be redeemed will
cease to accrue. Such notice shall also state the current Conversion Price and
the date on which the right to convert such Notes or portions thereof into
Common Stock will expire. If fewer than all the Notes are to be redeemed, the
notice of redemption shall identify the Notes to be redeemed (including CUSIP
numbers, if any). In case any Note 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 date fixed for redemption, upon
surrender of such Note, a new Note or Notes 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 3.2, 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 5.4) an amount of money in immediately available funds sufficient to
redeem on the redemption date all the Notes (or portions thereof) so called for
redemption (other than those theretofore surrendered for conversion into Common
Stock) at the appropriate redemption price, together with accrued interest to,
but excluding, the date fixed for redemption; provided, however, 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 3.2 in
excess of amounts required hereunder to pay the redemption price together with
accrued interest to, but excluding, the date fixed for redemption. If any Note
called for redemption is converted pursuant hereto prior to such redemption, any
money deposited with the Trustee or any paying agent or so segregated and held
in trust for the redemption of such Note 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 Notes 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 period of time as may be acceptable to the Trustee)
prior to the redemption date as to the aggregate principal amount of Notes to be
redeemed.

                                       31
<PAGE>

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

          Upon any redemption of less than all of the outstanding Notes, the
Company and the Trustee may (but need not), solely for purposes of determining
the pro rata allocation among such Notes as are unconverted and outstanding at
the time of redemption, treat as outstanding any Notes 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 Note
authenticated and delivered during such period in exchange for the unconverted
portion of any Note converted in part during such period.

          Section 3.3 PAYMENT OF NOTES CALLED FOR REDEMPTION. If notice of
redemption has been given as above provided, the Notes or portion of Notes with
respect to which such notice has been given shall, unless converted into Common
Stock pursuant to the terms hereof, 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 accrued to (but excluding) the date
fixed for redemption, and on and after said date (unless the Company shall
default in the payment of such Notes at the redemption price, together with
interest accrued to said date) interest on the Notes or portion of Notes so
called for redemption shall cease to accrue and, after the close of business on
the Business Day next preceding the date fixed for redemption, such Notes shall
cease to be convertible into Common Stock and, except as provided in Sections
8.5 and 13.4, to be entitled to any benefit or security under this Indenture,
and the holders thereof shall have no right in respect of such Notes except the
right to receive the redemption price thereof and unpaid

                                       32
<PAGE>

interest to (but excluding) the date fixed for redemption. On presentation and
surrender of such Notes at a place of payment in said notice specified, the said
Notes or the specified portions thereof shall be paid and redeemed by the
Company at the applicable redemption price, together with interest accrued
thereon to (but excluding) the date fixed for redemption; provided, however,
that if the applicable redemption date is an interest payment date, the
semi-annual payment of interest becoming due on such date shall be payable to
the holders of such Notes registered as such on the relevant record date instead
of the holders surrendering such Notes for redemption on such date.

          Upon presentation of any Note redeemed in part only, the Company shall
execute and the Trustee shall authenticate and make available for delivery to
the holder thereof, at the expense of the Company, a new Note or Notes, of
authorized denominations, in principal amount equal to the unredeemed portion of
the Notes so presented.

          Notwithstanding the foregoing, the Trustee shall not redeem any Notes
or mail any notice of redemption during the continuance of a default in payment
of interest or premium, if any, on the Notes. If any Note called for redemption
shall not be so paid upon surrender thereof for redemption, the principal and
premium, if any, shall, until paid or duly provided for, bear interest from the
date fixed for redemption at the rate borne by the Note and such Note shall
remain convertible into Common Stock until the principal and premium, if any,
and interest shall have been paid or duly provided for.

          Section 3.4 CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION. In
connection with any redemption of Notes, the Company may arrange for the
purchase and conversion of any Notes by an agreement with one or more investment
bankers or other purchasers to purchase such Notes by paying to the Trustee in
trust for the Noteholders, on or before the date fixed for redemption, an amount
not less than the applicable redemption price, together with interest accrued to
(but excluding) the date fixed for redemption, of such Notes. Notwithstanding
anything to the contrary contained in this Article Three, the obligation of the
Company to pay the redemption price of such Notes, together with interest
accrued to (but excluding) the date fixed for redemption, shall be deemed to be
satisfied and discharged to the extent such amount is so paid by such
purchasers. If such an agreement is entered into, a copy of which will be filed

                                       33
<PAGE>

with the Trustee prior to the date fixed for redemption, any Notes not duly
surrendered for conversion by the holders thereof may, at the option of the
Company, be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such holders and (notwithstanding anything to the contrary
contained in Article Fifteen) surrendered by such purchasers for conversion, all
as of immediately prior to the close of business on the date fixed for
redemption (and the right to convert any such Notes shall be extended through
such time), subject to payment of the above amount as aforesaid. At the
direction of the Company, the Trustee shall hold and dispose of any such amount
paid to it in the same manner as it would monies deposited with it by the
Company for the redemption of Notes. Without the Trustee's prior written
consent, no arrangement between the Company and such purchasers for the purchase
and conversion of any Notes shall increase or otherwise affect any of the
powers, duties, responsibilities or obligations of the Trustee as set forth in
this Indenture.

          Section 3.5  REDEMPTION AT OPTION OF HOLDERS.

          (a) If there shall occur a Fundamental Change at any time prior to
maturity of the Notes, then each Noteholder shall have the right, at such
holder's option, to require the Company to redeem all of such holder's Notes, or
any portion thereof that is an integral multiple of $1,000 principal amount, on
the date (the "Repurchase Date") that is thirty (30) days after the date of the
Company Notice (as defined in Section 3.5(b) below) of such Fundamental Change
(or, if such 30th day is not a Business Day, the immediately preceding Business
Day) at a redemption price equal to 100% of the principal amount thereof,
together with accrued interest to (but excluding) the Repurchase Date; provided,
however, that, if such Repurchase Date is a February 1 or August 1, then the
interest payable on such date shall be paid to the holders of record of the
Notes on the next preceding January 15 or July 15, respectively.

          Upon presentation of any Note redeemed in part only, the Company shall
execute and, upon the Company's written direction to the Trustee, the Trustee
shall authenticate and deliver to the holder thereof, at the expense of the
Company, a new Note or Notes, of authorized denominations, in principal amount
equal to the unredeemed portion of the Notes so presented.

                                       34
<PAGE>

          (b) On or before the tenth day after the occurrence of a Fundamental
Change, 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 Fundamental Change a notice (the "Company Notice") of the occurrence
of such Fundamental Change and of the redemption right at the option of the
holders arising as a result thereof. Such notice shall be mailed in the manner
and with the effect set forth in the first paragraph of Section 3.2 (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 Company Notice to the
Trustee at such time as it is mailed to Noteholders. Concurrently with the
mailing of any Company Notice, the Company shall issue a press release
announcing such Fundamental Change referred to in the Company Notice, the form
and content of which press 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 Company Notice or any proceedings
for the redemption of any Note which any Noteholder may elect to have the
Company repurchase as provided in this Section 3.5.

          Each Company Notice shall specify the circumstances constituting the
Fundamental Change, the Repurchase Date, the price at which the Company shall be
obligated to redeem Notes, that the holder must exercise the redemption right on
or prior to the close of business on the Repurchase Date (the "Fundamental
Change Expiration Time"), that the holder shall have the right to withdraw any
Notes surrendered prior to the Fundamental Change Expiration Time, a description
of the procedure which a Noteholder must follow to exercise such redemption
right and to withdraw any surrendered Notes, the place or places where the
holder is to surrender such holder's Notes, and the amount of interest accrued
on each Note to the Repurchase Date.

          No failure of the Company to give the foregoing notices and no defect
therein shall limit the Noteholders' redemption rights or affect the validity of
the proceedings for the repurchase of the Notes pursuant to this Section 3.5.

                                       35
<PAGE>

          (c) For a Note to be so redeemed 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 Note
with the form entitled "Option to Elect Repayment Upon A Fundamental Change" on
the reverse thereof duly completed, together with such Notes duly endorsed for
transfer, on or before the Fundamental Change Expiration Time. All questions as
to the validity, eligibility (including time of receipt) and acceptance of any
Note for repayment shall be determined by the Company, whose determination shall
be final and binding absent manifest error.

          (d) On or prior to the Repurchase Date, 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 5.4) an amount of money sufficient to repay on the Repurchase Date all
the Notes to be redeemed on such date at the appropriate redemption price,
together with accrued interest to (but excluding) the Repurchase Date; provided,
however, that if such payment is made on the 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 Notes surrendered for redemption (and not
withdrawn) prior to the Fundamental Change Expiration Time will be made promptly
(but in no event more than five (5) Business Days) following the Repurchase Date
by mailing checks for the amount payable to the holders of such Notes entitled
thereto as they shall appear on the registry books of the Company.

          (e) In the case of a reclassification, change, consolidation, merger,
combination, sale or conveyance to which Section 15.6 applies, in which the
Common Stock of the Company is changed or exchanged as a result into the right
to receive stock, securities or other property or assets (including cash), which
includes shares of Common Stock of the Company or shares of common stock of
another Person that are, or upon issuance will be, traded on a United States
national securities exchange or approved for trading on an established automated
over-the-counter trading market in the United States and such shares constitute
at the time such change or exchange becomes effective in excess of 50% of the
aggregate fair market value of such stock, securities or other property or
assets (including cash) (as determined by the Company, which determination shall
be conclusive and binding), then the Person formed by such consolidation or

                                       36
<PAGE>

resulting from such merger or which acquires such assets, as the case may be,
shall execute and deliver to the Trustee a supplemental indenture (accompanied
by an Opinion of Counsel that such supplemental indenture complies with the
Trust Indenture Act as in force at the date of execution of such supplemental
indenture) modifying the provisions of this Indenture relating to the right of
holders of the Notes to cause the Company to repurchase the Notes following a
Fundamental Change, including without limitation the applicable provisions of
this Section 3.5 and the definitions of Common Stock and Fundamental Change, as
appropriate, as determined in good faith by the Company (which determination
shall be conclusive and binding), to make such provisions apply to such other
Person if different from the Company and the common stock issued by such Person
(in lieu of the Company and the Common Stock of the Company).

          (f) The Company will comply with the provisions of Rule 13e-4 and any
other tender offer rules under the Exchange Act to the extent then applicable in
connection with the redemption rights of the holders of Notes in the event of a
Fundamental Change.

                                  ARTICLE FOUR

                             SUBORDINATION OF NOTES

          Section 4.1 AGREEMENT OF SUBORDINATION. The Company covenants and
agrees, and each holder of Notes issued hereunder by its acceptance thereof
likewise covenants and agrees, that all Notes shall be issued subject to the
provisions of this Article Four, and each Person holding any Note, whether upon
original issue or upon registration of transfer, assignment or exchange thereof,
accepts and agrees to be bound by such provisions.

          The payment of the principal of, premium, if any, and interest
(including Liquidated Damages, if any) on all Notes (including, but not limited
to, the redemption price with respect to the Notes called for redemption in
accordance with Section 3.2 or submitted for redemption in accordance with
Section 3.5, as the case may be, as provided in this Indenture) issued hereunder
shall, to the extent and in the manner hereinafter set forth, be subordinated
and subject in right of payment to the prior payment in full in cash or other
payment satisfactory to the holders of Senior Indebtedness of all Senior

                                       37
<PAGE>

Indebtedness, whether outstanding at the date of this Indenture or thereafter
incurred.

          No provision of this Article Four shall prevent the occurrence of any
default or Event of Default hereunder.

          Section 4.2 PAYMENTS TO NOTEHOLDERS. No payment shall be made with
respect to the principal of, premium, if any, or interest (including Liquidated
Damages, if any) on the Notes (including, but not limited to, the redemption
price with respect to the Notes to be called for redemption in accordance with
Section 3.2 or submitted for redemption in accordance with Section 3.5, as the
case may be, as provided in this Indenture), except payments and distributions
made by the Trustee as permitted by the first or second paragraph of Section
4.5, if:

           (i) a default in the payment of principal, premium, if any, interest,
     rent or other obligations in respect of Senior Indebtedness occurs and is
     continuing beyond any applicable period of grace (a "Payment Default"); or

          (ii) a default, other than a Payment Default, on any Designated Senior
     Indebtedness occurs and is continuing that then permits holders of such
     Designated Senior Indebtedness to accelerate its maturity and the Trustee
     receives a notice of the default (a "Payment Blockage Notice") from a
     holder of Designated Senior Indebtedness, a Representative of Designated
     Senior Indebtedness or the Company (a "Non-Payment Default").

          If the Trustee receives any Payment Blockage Notice pursuant to clause
(ii) above, no subsequent Payment Blockage Notice shall be effective for
purposes of this Section 4.2 unless and until (A) at least 365 days shall have
elapsed since the initial effectiveness of the immediately prior Payment
Blockage Notice and (B) all scheduled payments of principal, premium, if any,
and interest (including Liquidated Damages, if any) on the Notes that have come
due have been paid in full in cash. No Non-Payment Default that existed or was
continuing on the date of delivery of any Payment Blockage Notice to the Trustee
shall be, or be made, the basis for a subsequent Payment Blockage Notice.

                                       38
<PAGE>

          The Company may and shall resume payments on and distributions in
respect of the Notes upon:

          (1) in the case of a Payment Default, the date upon which any such
     Payment Default is cured or waived or ceases to exist, or

          (2) in the case of a Non-Payment Default, the earlier of (a) the date
     upon which such default is cured or waived or ceases to exist or (b) 179
     days after the applicable Payment Blockage Notice is received by the
     Trustee,

unless this Article Four otherwise prohibits the payment or distribution at the
time of such payment or distribution.

          Upon any payment by the Company, or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding up or liquidation or reorganization of
the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due or to become due upon all
Senior Indebtedness shall first be paid in full in cash or other payment
satisfactory to the holders of such Senior Indebtedness, or payment thereof in
accordance with its terms provided for in cash or other payment satisfactory to
the holders of such Senior Indebtedness before any payment is made on account of
the principal of, premium, if any, or interest (including Liquidated Damages, if
any) on the Notes (except payments made pursuant to Article Thirteen from monies
deposited with the Trustee pursuant thereto prior to commencement of proceedings
for such dissolution, winding up, liquidation or reorganization), and upon any
such dissolution or winding up or liquidation or reorganization of the Company
or bankruptcy, insolvency, receivership or other proceeding, any payment by the
Company, or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to which the holders of the Notes or
the Trustee would be entitled, except for the provisions of this Article Four,
shall (except as aforesaid) be paid by the Company or by any receiver, trustee
in bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the holders of the Notes or by the Trustee under this
Indenture if received by them or it, directly to the holders of Senior
Indebtedness (pro rata to such holders on the basis of the respective amounts of
Senior Indebtedness held

                                       39
<PAGE>

by such holders, or as otherwise required by law or a court order) or their
Representative or Representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any Senior Indebtedness
may have been issued, as their respective interests may appear, to the extent
necessary to pay all Senior Indebtedness in full in cash or other payment
satisfactory to the holders of such Senior Indebtedness, after giving effect to
any concurrent payment or distribution to or for the holders of Senior
Indebtedness, before any payment or distribution is made to the holders of the
Notes or to the Trustee.

          For purposes of this Article Four, the words, "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article Four with
respect to the Notes to the payment of all Senior Indebtedness which may at the
time be outstanding. The consolidation of the Company with, or the merger of the
Company into, another Person or the liquidation or dissolution of the Company
following the conveyance or transfer of its property as an entirety, or
substantially as an entirety, to another Person upon the terms and conditions
provided for in Article Twelve shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section 4.2 if such other
Person shall, as a part of such consolidation, merger, conveyance or transfer,
comply with the conditions stated in Article Twelve.

          In the event of the acceleration of the Notes because of an Event of
Default, no payment or distribution shall be made to the Trustee or any holder
of Notes in respect of the principal of, premium, if any, or interest (including
Liquidated Damages, if any) on the Notes (including, but not limited to, the
redemption price with respect to the Notes called for redemption in accordance
with Section 3.2 or submitted for redemption at the option of the holder in
accordance with Section 3.5, as the case may be, as provided in this Indenture),
except payments and distributions made by the Trustee as permitted by the first
or second paragraph of Section 4.5, until all Senior Indebtedness has been paid
in full in cash or other payment satisfactory to the holders of Senior
Indebtedness or such acceleration is rescinded in accordance with the terms of
this Indenture. If payment of the Notes is accelerated

                                       40
<PAGE>

because of an Event of Default, the Company or the Trustee shall promptly notify
holders of Senior Indebtedness of the acceleration.

          In the event that, notwithstanding the foregoing provisions, any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities (including, without limitation, by way
of setoff or otherwise), prohibited by the foregoing provisions in this Section
4.2, shall be received by the Trustee or the holders of the Notes before all
Senior Indebtedness is paid in full in cash or other payment satisfactory to the
holders of such Senior Indebtedness, or provision is made for such payment
thereof in accordance with its terms in cash or other payment satisfactory to
the holders of such Senior Indebtedness, such payment or distribution shall be
held in trust for the benefit of and shall be paid over or delivered to the
holders of Senior Indebtedness or their Representative or Representatives, or to
the trustee or trustees under any indenture pursuant to which any instruments
evidencing any Senior Indebtedness may have been issued, as their respective
interests may appear, as calculated by the Company, for application to the
payment of any Senior Indebtedness remaining unpaid to the extent necessary to
pay all Senior Indebtedness in full in cash or other payment satisfactory to the
holders of such Senior Indebtedness, after giving effect to any concurrent
payment or distribution to or for the holders of such Senior Indebtedness.

          Nothing in this Section 4.2 shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 8.6. This Section 4.2 shall be subject
to the further provisions of Section 4.5.

          Section 4.3 SUBROGATION OF NOTES. Subject to the payment in full of
all Senior Indebtedness, the rights of the holders of the Notes shall be
subrogated to the extent of the payments or distributions made to the holders of
such Senior Indebtedness pursuant to the provisions of this Article Four
(equally and ratably with the holders of all indebtedness of the Company that by
its express terms, is subordinated to other indebtedness of the Company to
substantially the same extent as the Notes are subordinated and is entitled to
like rights of subrogation) to the rights of the holders of Senior Indebtedness
to receive payments or distributions of cash, property or securities of the
Company applicable to the Senior Indebtedness until the principal,

                                       41
<PAGE>

premium, if any, and interest (including Liquidated Damages, if any) on the
Notes shall be paid in full, and, for the purposes of such subrogation, no
payments or distributions to the holders of the Senior Indebtedness of any cash,
property or securities to which the holders of the Notes or the Trustee would be
entitled except for the provisions of this Article Four, and no payment over
pursuant to the provisions of this Article Four, to or for the benefit of the
holders of Senior Indebtedness by holders of the Notes or the Trustee, shall, as
among the Company, its creditors other than holders of Senior Indebtedness, and
the holders of the Notes, be deemed to be a payment by the Company to or on
account of the Senior Indebtedness, and no payments or distributions of cash,
property or securities to or for the benefit of the holders of the Notes
pursuant to the subrogation provisions of this Article Four, which would
otherwise have been paid to the holders of Senior Indebtedness, shall be deemed
to be a payment by the Company to or for the account of the Notes. It is
understood that the provisions of this Article Four are and are intended solely
for the purposes of defining the relative rights of the holders of the Notes, on
the one hand, and the holders of the Senior Indebtedness, on the other hand.

          Nothing contained in this Article Four or elsewhere in this Indenture
or in the Notes is intended to or shall impair, as among the Company, its
creditors other than the holders of Senior Indebtedness, and the holders of the
Notes, the obligation of the Company, which is absolute and unconditional, to
pay to the holders of the Notes the principal of, premium, if any, and interest
(including Liquidated Damages, if any) on the Notes as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the holders of the Notes and creditors of
the Company other than the holders of the Senior Indebtedness, nor shall
anything herein or therein prevent the Trustee or the holder of any Note from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article Four of the
holders of Senior Indebtedness in respect of cash, property or securities of the
Company received upon the exercise of any such remedy.

          Upon any payment or distribution of assets of the Company referred to
in this Article Four, the Trustee, subject to the provisions of Section 8.1, and
the holders of the Notes shall be entitled to rely upon any order or decree

                                       42
<PAGE>

made by any court of competent jurisdiction in which such bankruptcy,
dissolution, winding up, liquidation or reorganization proceedings are pending,
or a certificate of the receiver, trustee in bankruptcy, liquidating trustee,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the holders of the Notes, 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, the amount thereof or
payable thereon and all other facts pertinent thereto or to this Article Four.

          Section 4.4 AUTHORIZATION TO EFFECT Subordination. Each holder of a
Note, by its acceptance thereof, authorizes and directs the Trustee on the
holder's behalf to take such action as may be necessary or appropriate to
effectuate the subordination as provided in this Article Four and appoints the
Trustee to act as the 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 the third paragraph of Section
7.2 hereof at least thirty (30) days before the expiration of the time to file
such claim, the holders of any Senior Indebtedness or their representatives are
hereby authorized to file an appropriate claim for and on behalf of the holders
of the Notes.

          Section 4.5 NOTICE TO TRUSTEE. The Company shall give prompt written
notice in the form of an Officers' Certificate to a Responsible Officer of the
Trustee and to any paying agent of any fact known to the Company that would
prohibit the making of any payment of monies to or by the Trustee or any paying
agent in respect of the Notes pursuant to the provisions of this Article Four.
Notwithstanding the provisions of this Article Four 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 of monies to or by
the Trustee in respect of the Notes pursuant to the provisions of this Article
Four, unless and until a Responsible Officer of the Trustee shall have received
written notice thereof at the Corporate Trust Office from the Company (in the
form of an Officers' Certificate) or a Representative or a holder or holders of
Senior Indebtedness or from any trustee thereof, and before the receipt of any
such written notice, the Trustee, subject to the provisions of Section 8.1,
shall be entitled in all respects to assume that no such facts exist; provided,
however, that if on a date not less than two

                                       43
<PAGE>

Business Days prior to the date upon which by the terms hereof any such monies
may become payable for any purpose (including, without limitation, the payment
of the principal of, or premium, if any, or interest (including Liquidated
Damages, if any) on any Note) the Trustee shall not have received, with respect
to such monies, the notice provided for in this Section 4.5, then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full
power and authority to apply monies received to the purpose for which they were
received, and shall not be affected by any notice to the contrary that may be
received by it on or after such prior date.

          Notwithstanding anything in this Article Four to the contrary, nothing
shall prevent any payment by the Trustee to the Noteholders of monies deposited
with it pursuant to Section 13.1, and any such payment shall not be subject to
the provisions of Section 4.1 or 4.2.

          The Trustee, subject to the provisions of Section 8.1, shall be
entitled to rely on the delivery to it of a written notice by a Representative
or a person representing himself to be a holder of Senior Indebtedness (or a
trustee on behalf of such holder) to establish that such notice has been given
by a Representative or a holder of Senior Indebtedness or a trustee on behalf of
any such holder or holders. The Trustee shall not be required to make any
payment or distribution to or on behalf of a holder of Senior Indebtedness
pursuant to this Article Four unless it has received satisfactory evidence 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 Four.

          Section 4.6 TRUSTEE'S RELATION TO SENIOR INDEBTEDNESS. The Trustee, in
its individual capacity, shall be entitled to all the rights set forth in this
Article Four in respect of any Senior Indebtedness at any time held by it, to
the same extent as any other holder of Senior Indebtedness, and nothing in
Section 8.13 or elsewhere in this Indenture shall deprive the Trustee of any of
its rights as such holder.

          With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article Four, and no implied

                                       44
<PAGE>

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,
subject to the provisions of Section 8.1, the Trustee shall not be liable to any
holder of Senior Indebtedness (i) for any failure to make any payments or
distributions to such holder or (ii) if it shall pay over or deliver to holders
of Notes, the Company or any other Person money or assets to which any holder of
Senior Indebtedness shall be entitled by virtue of this Article Four or
otherwise.

          Section 4.7 NO IMPAIRMENT OF SUBORDINATION. No right of any present or
future holder of any Senior Indebtedness to enforce subordination as herein
provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or failure to act, in
good faith, by any such holder, or by any noncompliance by the Company with the
terms, provisions and covenants of this Indenture, regardless of any knowledge
thereof which any such holder may have or otherwise be charged with.

          Section 4.8 CERTAIN CONVERSIONS NOT DEEMED PAYMENT. For the purposes
of this Article Four only, (1) the issuance and delivery of junior securities
upon conversion of Notes in accordance with Article Fifteen shall not be deemed
to constitute a payment or distribution on account of the principal of, premium,
if any, or interest (including Liquidated Damages, if any) on Notes or on
account of the purchase or other acquisition of Notes, and (2) the payment,
issuance or delivery of cash (except in satisfaction of fractional shares
pursuant to Section 15.3), property or securities (other than junior securities)
upon conversion of a Note shall be deemed to constitute payment on account of
the principal of, premium, if any, or interest (including Liquidated Damages, if
any) on such Note. For the purposes of this Section 4.8, the term "junior
securities" means (a) shares of any stock of any class of the Company or (b)
securities of the Company that are subordinated in right of payment to all
Senior Indebtedness that may be outstanding at the time of issuance or delivery
of such securities to substantially the same extent as, or to a greater extent
than, the Notes are so subordinated as provided in this Article Four. Nothing
contained in this Article Four or elsewhere in this Indenture or in the Notes is
intended to or shall impair, as among the Company, its creditors (other than
holders of Senior Indebtedness) and

                                       45
<PAGE>

the Noteholders, the right, which is absolute and unconditional, of the Holder
of any Note to convert such Note in accordance with Article Fifteen.

          Section 4.9 ARTICLE APPLICABLE TO PAYING Agents. If at any time any
paying agent other than the Trustee shall have been appointed by the Company and
be then acting hereunder, the term "Trustee" as used in this Article Four shall
(unless the context otherwise requires) be construed as extending to and
including such paying agent within its meaning as fully for all intents and
purposes as if such paying agent were named in this Article Four in addition to
or in place of the Trustee; provided, however, that the first paragraph of
Section 4.5 shall not apply to the Company or any Affiliate of the Company if it
or such Affiliate acts as paying agent.

          The Trustee shall not be responsible for the actions or inactions of
any other paying agents (including the Company if acting as its own paying
agent) and shall have no control of any funds held by such other paying agents.

          Section 4.10 SENIOR INDEBTEDNESS ENTITLED TO Rely. The holders of
Senior Indebtedness (including, without limitation, Designated Senior
Indebtedness) shall have the right to rely upon this Article Four, and no
amendment or modification of the provisions contained herein shall diminish the
rights of such holders unless such holders shall have agreed in writing thereto.

          Section 4.11 RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING
AGENT. Upon any payment or distribution of assets of the Company referred to in
this Article Four, the Trustee and the Noteholders shall be entitled to rely
upon any order or decree entered by any court of competent jurisdiction in which
such insolvency, bankruptcy, receivership, liquidation, reorganization,
dissolution, winding up or similar case or proceeding is pending, or a
certificate of the trustee in bankruptcy, liquidating trustee, custodian,
receiver, assignee for the benefit of creditors, agent or other Person making
such payment or distribution, delivered to the Trustee or to the Noteholders,
for the purpose of ascertaining the Persons entitled to participate in such
payment or distribution, the holders of Senior Indebtedness and other
indebtedness of the Company, the amount thereof or payable thereon, the amount

                                       46
<PAGE>

or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article Four.

demands to or upon the Company in respect of the Notes 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 of the Trustee at 14 Wall
Street, 8th floor, Window 2, New York, New York 10005, Attention: Corporate
Trust Administration.

          The Company may also from time to time designate co-registrars and one
or more offices or agencies where the Notes 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,
Note registrar, Custodian and conversion agent and the Corporate Trust Office of

<PAGE>

as the office or agency of the Company for each of the aforesaid purposes.

          So long as the Trustee is the Note registrar, the Trustee agrees to
mail, or cause to be mailed, the notices set forth in Section 8.10(a) and the
third paragraph of Section 8.11. 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 Notes it can identify from its records.

          Section 5.3 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 8.10, a Trustee, so that there
shall at all times be a Trustee hereunder.

          Section 5.4  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 5.4:

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

          (2) that it will give the Trustee notice of any failure by the Company
     (or by any other obligor on the Notes) to make any payment of the principal

     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,
premium, if any, or interest on the Notes, deposit with the paying agent a sum
(in funds which are immediately available on the due date for such payment)
sufficient to pay such principal, premium, if any, or

                                       48
<PAGE>

interest, and (unless such paying agent is the Trustee) the Company will
promptly notify the Trustee of any failure to take such action; provided,
however, 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, premium, if any, or interest
(including Liquidated Damages, if any) on the Notes, set aside, segregate and
hold in trust for the benefit of the holders of the Notes a sum sufficient to
pay such principal, premium, if any, or interest (including Liquidated Damages,
if any) 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 obligor under
the Notes) to make any payment of the principal of, premium, if any, or interest
(including Liquidated Damages, if any) on the Notes when the same shall become
due and payable.

          (c) Anything in this Section 5.4 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 5.4, 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.

          (d) Anything in this Section 5.4 to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section 5.4 is subject to
Sections 13.3 and 13.4.

          The Trustee shall not be responsible for the actions of any other
paying agents (including the Company if acting as its own paying agent) and
shall have no control of any funds held by such other paying agents.

          Section 5.5 EXISTENCE. Subject to Article Twelve, the Company will do
or cause to be done all things necessary to preserve and keep in full force and
effect its existence and rights (charter and statutory); provided, however, that
the Company shall not be required to preserve any such right if the Company
shall determine that the

                                       49
<PAGE>

preservation thereof is no longer desirable in the conduct of the business of
the Company and that the loss thereof is not disadvantageous in any material
respect to the Noteholders.

          Section 5.6 MAINTENANCE OF PROPERTIES. The Company will cause all
properties used or useful in the conduct of its business or the business of any
Significant Subsidiary to be maintained and kept in good condition, repair and
working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section shall
prevent the Company from discontinuing the operation or maintenance of any of
such properties if such discontinuance is, in the judgment of the Company,
desirable in the conduct of its business or the business of any subsidiary and
not disadvantageous in any material respect to the Noteholders.

          Section 5.7 PAYMENT OF TAXES AND OTHER CLAIMS. The Company will pay or
discharge, or cause to be paid or discharged, before the same may become
delinquent, (i) all taxes, assessments and governmental charges levied or
imposed upon the Company or any Significant Subsidiary or upon the income,
profits or property of the Company or any Significant Subsidiary, (ii) all
claims for labor, materials and supplies which, if unpaid, might by law become a
lien or charge upon the property of the Company or any Significant Subsidiary
and (iii) all stamps and other duties, if any, which may be imposed by the
United States or any political subdivision thereof or therein in connection with
the issuance, transfer, exchange or conversion of any Notes or with respect to
this Indenture; provided, however, that, in the case of clauses (i) and (ii),
the Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim (A) if the failure to do so
will not, in the aggregate, have a material adverse impact on the Company, or
(B) if the amount, applicability or validity is being contested in good faith by
appropriate proceedings.

          Section 5.8 RULE 144A INFORMATION REQUIREMENT. Within the period prior
to the expiration of the holding period applicable to sales thereof under Rule
144(k) under

                                       50
<PAGE>

the Securities Act (or any successor provision), the Company covenants and
agrees that it shall, during any period in which it is not subject to Section 13
or 15(d) under the Exchange Act, make available to any holder or beneficial
holder of Notes or any Common Stock issued upon conversion thereof which
continue to be Restricted Securities in connection with any sale thereof and any
prospective purchaser of Notes or such Common Stock 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
Notes or such Common Stock and it will take such further action as any holder or
beneficial holder of such Notes 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 Notes 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 Notes or such Common Stock, the Company will
deliver to such holder a written statement as to whether it has complied with
such requirements.

          Section 5.9 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 which would prohibit or
forgive the Company from paying all or any portion of the principal of, premium,
if any, or interest (including Liquidated Damages, if any) on the Notes as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which 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 5.10 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, a certificate signed by either the principal executive officer,
principal financial officer or principal accounting officer of the Company,
stating whether or not to the best knowledge of the signer thereof the Company
is in default in

                                       51
<PAGE>

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 (and in any event
within five Business Days) upon becoming aware of (i) any default in the
performance or observance of any covenant, agreement or condition contained in

respect thereto.

          Any notice required to be given under this Section 5.10 shall be
delivered to a Responsible Officer of the Trustee at its Corporate Trust Office.

          Section 5.11 AMENDMENT OF THE COMPANY'S RIGHTS PLAN. The Company shall
use all reasonable efforts (i) to amend its Rights Agreement with ChaseMellon
Shareholder Services, L.L.C., as Rights Agent, dated as of November 30, 1998
(the "Rights Agreement") to provide, and (ii) to cause any future shareholder
rights plans of the Company to provide, that upon conversion of the Notes into
Common Stock as provided in Article Fifteen of this Indenture, to the extent
that the Rights Agreement (or any such future shareholder rights plan) and any
rights granted thereunder remain in effect and outstanding at the time of such
conversion, holders of the Notes will receive, in addition to Common Stock, the
Rights (as described in the Rights Agreement or any similar securities as
described in any such future shareholder rights plan), whether or not such
Rights have separated from the Common Stock at the time of conversion, subject
to such exceptions as are set forth in the Rights Agreement and apply to all
holders of Common Stock or Rights other than any Acquiring Person (as defined in
the Rights Agreement) or such customary exceptions as may be set forth in any
such future shareholder rights plan; provided, however, that nothing in this
Indenture shall obligate the Company to maintain in effect the Rights Agreement

                         BY THE COMPANY AND THE TRUSTEE

          Section 6.1 NOTEHOLDERS' LISTS. The Company covenants and agrees that
it will furnish or cause to be furnished to the Trustee, semiannually, not more

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 Notes as of a date not more than fifteen (15) days (or such other
date as the Trustee may reasonably request in order to so provide any such
notices) prior to the time such information is furnished, except that no such
list need be furnished by the Company to the Trustee so long as the Trustee is
acting as the sole Note registrar.

          Section 6.2  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
Notes contained in the most recent list furnished to it as provided in Section
6.1 or maintained by the Trustee in its capacity as Note registrar or
co-registrar in respect of the Notes, if so acting. The Trustee may destroy any

furnished.

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

          (c) Every Noteholder, by receiving and holding the same, agrees with

          Section 6.3  REPORTS BY TRUSTEE.

          (a) Within sixty (60) days after May 15 of each year commencing with
the year 2001, the Trustee shall transmit to holders of Notes such reports dated
as of May 15 of the year in which such reports are made concerning the Trustee
and its actions under this Indenture as may be required pursuant to the Trust
Indenture Act at the times and in the manner provided pursuant thereto.

          (b) A copy of such report shall, at the time of such transmission to
holders of Notes, be filed by the Trustee with each stock exchange and automated
quotation system upon which the Notes are listed and with the Company. The
Company will promptly notify the Trustee in writing when the Notes are listed on
any stock exchange or automated quotation system or delisted therefrom.

          Section 6.4 REPORTS BY COMPANY. The Company shall file with the
Trustee (and the Commission if at any time after the Indenture becomes qualified
under the Trust Indenture Act), and transmit to holders of Notes, such
information, documents and other reports and such summaries thereof, as may be
required pursuant to the Trust Indenture Act at the times and in the manner
provided pursuant to such Act, whether or not the Notes are governed by such
Act; provided, however, that any such information, documents or reports required
to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange
Act shall be filed with the Trustee within 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 Officers'
Certificates).

                                  ARTICLE SEVEN

                           REMEDIES OF THE TRUSTEE AND
                       NOTEHOLDERS ON AN EVENT OF DEFAULT

          Section 7.1 EVENTS OF DEFAULT. In case one or more of the following
Events of Default (whatever the reason for such Event of Default and whether it
shall be voluntary

                                       54
<PAGE>

or involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body) shall have occurred and be continuing:

                  (a) default in the payment of any installment of interest
         (including Liquidated Damages, if any) upon any of the Notes as and
         when the same shall become due and payable, and continuance of such
         default for a period of thirty (30) days, whether or not such payment
         is permitted under Article Four hereof; or

                  (b) default in the payment of the principal of or premium, if
         any, on any of the Notes as and when the same shall become due and
         payable either at maturity or in connection with any redemption
         pursuant to Article Three, by acceleration or otherwise, whether or not
         such payment is permitted under Article Four hereof; or

                  (c) failure on the part of the Company duly to observe or
         perform any other of the covenants or agreements on the part of the
         Company in the Notes or in this Indenture (other than a covenant or
         agreement a default in whose performance or whose breach is elsewhere
         in this Section 7.1 specifically 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 a Responsible Officer of the
         Trustee by the holders of at least twenty-five percent (25%) in
         aggregate principal amount of the Notes at the time outstanding
         determined in accordance with Section 9.4; or

                  (d) the Company or any Significant Subsidiary shall commence a
         voluntary case or other proceeding seeking liquidation, reorganization
         or other relief with respect to itself or any Significant Subsidiary or
         its or such Significant Subsidiary's 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 it or any Significant Subsidiary or any substantial
         part of the property of the Company or any Significant Subsidiary, 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 it or any

                                       55
<PAGE>

         Significant Subsidiary, or shall make a general assignment for the
         benefit of creditors, or shall fail generally to pay its debts as they
         become due; or

                  (e) an involuntary case or other proceeding shall be commenced
         against the Company or any Significant Subsidiary seeking liquidation,
         reorganization or other relief with respect to it or any Significant
         Subsidiary or its or such Significant Subsidiary's 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 it or any Significant Subsidiary
         or any substantial part of the property of the Company or any
         Significant Subsidiary, and such involuntary case or other proceeding
         shall remain undismissed and unstayed for a period of ninety (90)
         consecutive days;

then, and in each and every such case (other than an Event of Default specified
in Section 7.1(d) or (e) with respect to the Company), unless the principal of
all of the Notes 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 Notes then outstanding hereunder determined in accordance with
Section 9.4, by notice in writing to the Company (and to the Trustee if given by
Noteholders), may declare the principal of and premium, if any, on all the Notes
and the interest accrued thereon (including Liquidated Damages, if any) 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
Notes contained to the contrary notwithstanding. If an Event of Default
specified in Section 7.1(d) or (e) with respect to the Company occurs, the
principal of all the Notes and the interest accrued thereon shall (including
Liquidated Damages, if any) 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 Notes 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

                                       56
<PAGE>

of interest upon (including Liquidated Damages, if any) all Notes and the
principal of and premium, if any, on any and all Notes which shall have become
due otherwise than by acceleration (with interest on overdue installments of
interest (including Liquidated Damages, if any) (to the extent that payment of
such interest is enforceable under applicable law) and on such principal and
premium, if any, at the rate borne by the Notes, to the date of such payment or
deposit) and amounts due to the Trustee pursuant to Section 8.6, and if any and
all defaults under this Indenture, other than the nonpayment of principal of and
premium, if any, and accrued interest on (including Liquidated Damages, if any)
Notes which shall have become due by acceleration, shall have been cured or
waived pursuant to Section 7.7, then and in every such case the holders of a
majority in aggregate principal amount of the Notes 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, or shall impair any right consequent
thereon. The Company shall notify a Responsible Officer of the Trustee, promptly
(and in any event within five Business Days) 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 Notes, 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 Notes, and the Trustee shall
continue as though no such proceeding had been taken.

          Section 7.2 PAYMENTS OF NOTES ON DEFAULT; SUIT THEREFOR. The Company
covenants that (a) in case default shall be made in the payment of any
installment of interest upon (including Liquidated Damages, if any) any of the
Notes 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 or premium, if any, on any of the Notes
as and when the same shall have become due

                                       57
<PAGE>

and payable, whether at maturity of the Notes or in connection with any
redemption, by or under this Indenture declaration or otherwise, then, upon
demand of the Trustee, the Company will pay to the Trustee, for the benefit of
the holders of the Notes, the whole amount that then shall have become due and
payable on all such Notes for principal and premium, if any, or interest
(including Liquidated Damages, if any), as the case may be, with interest upon
the overdue principal and premium, if any, and (to the extent that payment of
such interest is enforceable under applicable law) upon the overdue installments
of interest (including Liquidated Damages, if any) at the rate borne by the
Notes, 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 8.6. Until such demand by the Trustee, the Company may pay
the principal of and premium, if any, and interest on (including Liquidated
Damages, if any) the Notes to the registered holders, whether or not the Notes
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 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 decree, and may enforce any such
judgment or final decree against the Company or any other obligor on the Notes
and collect in the manner provided by law out of the property of the Company or
any other obligor on the Notes 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 or any other obligor on the Notes 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 or such other obligor, the property of the Company or
such other obligor, or in the case of any other judicial proceedings relative to
the Company or such other obligor upon the Notes, or to the creditors or
property of the Company or such other obligor, the Trustee, irrespective of
whether the principal of the Notes 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 7.2, shall
be entitled and empowered, by intervention in such proceedings or otherwise, to
file and prove a claim or

                                       58
<PAGE>

claims for the whole amount of principal, premium, if any, and interest
(including Liquidated Damages, if any) owing and unpaid in respect of the Notes,
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 Noteholders allowed in such judicial proceedings
relative to the Company or any other obligor on the Notes, 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 8.6, and
any receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
custodian or similar official is hereby authorized by each of the Noteholders 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 Noteholders, to pay to
the Trustee any amount due it for reasonable compensation, expenses, advances
and disbursements, including counsel fees 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 which the holders of the Notes may be entitled to
receive in such proceedings, whether in liquidation or under any plan of
reorganization or arrangement or otherwise.

          All rights of action and of asserting claims under this Indenture, or
under any of the Notes, may be enforced by the Trustee without the possession of
any of the Notes, 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 agent and
counsel, be for the ratable benefit of the holders of the Notes.

          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 Notes, and it shall not be necessary to make any holders of the Notes
parties to any such proceedings.

          Section 7.3 APPLICATION OF MONIES COLLECTED BY TRUSTEE. Any monies
collected by the Trustee pursuant to this Article Seven shall be applied in the
order following, at the date or dates fixed by the Trustee for the distribution
of such monies, upon presentation of the several Notes, and stamping thereon the
payment, if only partially paid, and upon surrender thereof, if fully paid:

                  FIRST: To the payment of all amounts due the Trustee under
         Section 8.6;

                  SECOND: Subject to the provisions of Article Four, in case the
         principal of the outstanding Notes shall not have become due and be
         unpaid, to the payment of interest on (including Liquidated Damages, if
         any) the Notes in default in the order of the maturity of the
         installments of such interest, with interest (to the extent that such
         interest has been collected by the Trustee) upon the overdue
         installments of interest (including Liquidated Damages, if any) at the
         rate borne by the Notes, such payments to be made ratably to the
         Persons entitled thereto;

                  THIRD: Subject to the provisions of Article Four, in case the
         principal of the outstanding Notes shall have become due, by
         declaration or otherwise, and be unpaid to the payment of the whole
         amount then owing and unpaid upon the Notes for principal and premium,
         if any, and interest (including Liquidated Damages, if any), with
         interest on the overdue principal and premium, if any, and (to the
         extent that such interest has been collected by the Trustee) upon
         overdue installments of interest (including Liquidated Damages, if any)
         at the rate borne by the Notes, and in case such monies shall be
         insufficient to pay in full the whole amounts so due and unpaid upon
         the Notes, then to the payment of such principal and premium, if any,
         and interest (including Liquidated Damages, if any) without preference
         or priority of principal and premium, if any, over interest (including
         Liquidated Damages, if any), or of interest (including Liquidated
         Damages, if any) over principal and premium, if any, or of any
         installment of interest over any other installment of interest, or of
         any Note over any other Note, ratably to the aggregate of such
         principal and premium, if any, and accrued and unpaid interest; and

                                       60
<PAGE>

                  FOURTH: Subject to the provisions of Article Four, to the
         payment of the remainder, if any, to the Company or any other Person
         lawfully entitled thereto.

          Section 7.4 PROCEEDINGS BY NOTEHOLDER. No holder of any Note 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 such holder previously shall have given to the Trustee written
notice of an Event of Default and of the continuance thereof, as hereinbefore
provided, and unless also the holders of not less than twenty-five percent (25%)
in aggregate principal amount of the Notes 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
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, and the Trustee for sixty (60) days after its
receipt of such notice, request and offer of indemnity, shall have neglected or
refused to institute any such action, suit or proceeding and no direction
inconsistent with such written request shall have been given to the Trustee
pursuant to Section 7.7; it being understood and intended, and being expressly
covenanted by the taker and holder of every Note with every other taker and
holder and the Trustee, that no one or more holders of Notes 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
Notes, 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
Notes (except as otherwise provided herein). For the protection and enforcement
of this Section 7.4, each and every Noteholder 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 Note, the right of any holder of any Note to receive payment of
the principal of and premium, if any (including the redemption price upon
redemption pursuant to Article Three), and accrued interest on (including
Liquidated Damages, if any) such Note, on or

                                       61
<PAGE>

after the respective due dates expressed in such Note or in the event of
redemption, or to institute suit for the enforcement of any such payment on or
after such respective dates against the Company shall not be impaired or
affected without the consent of such holder.

          Anything in this Indenture or the Notes to the contrary
notwithstanding, the holder of any Note, without the consent of either the
Trustee or the holder of any other Note, in 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 7.5 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 7.6 REMEDIES CUMULATIVE AND CONTINUING. Except as provided in
Section 2.6, all powers and remedies given by this Article Seven to the Trustee
or to the Noteholders 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 Notes, 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 Notes 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
7.4, every power and remedy given by this Article Seven or by law to the Trustee
or to the Noteholders may be exercised from time to time, and as often as shall
be deemed expedient, by the Trustee or by the Noteholders.

          Section 7.7 DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY
MAJORITY OF NOTEHOLDERS. The holders of a majority in aggregate principal amount
of the Notes at the time outstanding determined in accordance with Section 9.4
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, however, 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 which is not inconsistent with such direction and (c)
the Trustee may decline to take any action that would benefit some Noteholder to
the detriment of other Noteholders. The holders of a majority in aggregate
principal amount of the Notes at the time outstanding determined in accordance
with Section 9.4 may, on behalf of the holders of all of the Notes, waive any
past default or Event of Default hereunder and its consequences except (i) a
default in the payment of interest (including Liquidated Damages, if any) or
premium, if any, on, or the principal of, the Notes, (ii) a failure by the
Company to convert any Notes into Common Stock, (iii) a default in the payment
of redemption price pursuant to Article Three or (iv) a default in respect of a
covenant or provisions hereof which under Article Eleven cannot be modified or
amended without the consent of the holders of each or all Notes then outstanding
or affected thereby. Upon any such waiver, the Company, the Trustee and the
holders of the Notes 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 or impair any right consequent thereon. Whenever any default or
Event of Default hereunder shall have been waived as permitted by this Section
7.7, said default or Event of Default shall for all purposes of the Notes 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
or impair any right consequent thereon.

          Section 7.8 NOTICE OF DEFAULTS. The Trustee shall, within ninety (90)
days after a Responsible Officer of the Trustee has actual knowledge of the
occurrence of a default, mail to all Noteholders, as the names and addresses of
such holders appear upon the Note register, notice of all defaults actually
known to a Responsible Officer, unless such defaults shall have been cured or
waived before the giving of such notice; provided, however, that except in the
case of default in the payment of the principal of, or

                                       63
<PAGE>

premium, if any, or interest (including Liquidated Damages, if any) on any of
the Notes, 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 Noteholders.

          Section 7.9 UNDERTAKING TO PAY COSTS. All parties to this Indenture
agree, and each holder of any Note 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, however, that the provisions of this
Section 7.9 (to the extent permitted by law) shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Noteholder, or group of
Noteholders, holding in the aggregate more than ten percent in principal amount
of the Notes at the time outstanding determined in accordance with Section 9.4,
or to any suit instituted by any Noteholder for the enforcement of the payment
of the principal of or premium, if any, or interest on any Note on or after the
due date expressed in such Note or to any suit for the enforcement of the right
to convert any Note in accordance with the provisions of Article Fifteen.

                                  ARTICLE EIGHT

                                   THE TRUSTEE

          Section 8.1 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 which 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.

                                       64
<PAGE>

          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 which may have occurred:

                           (1) 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

                           (2) in the absence of bad faith and 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 which 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;

                  (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 Notes at the time outstanding determined as
         provided in Section 9.4 relating to the time, method and place of
         conducting any proceeding for any remedy available to the Trustee, or
         exercising any trust or power conferred upon the Trustee, under this
         Indenture;

                                       65
<PAGE>

                  (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 Notes; and

                  (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.

          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 8.2 RELIANCE ON DOCUMENTS, OPINIONS, Etc. Except as otherwise
provided in Section 8.1:

                  (a) the Trustee may conclusively rely and shall be fully
         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
         may be evidenced to the Trustee by a copy

                                       66
<PAGE>

         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;

                  (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 Noteholders pursuant to the provisions
         of this Indenture, unless such Noteholders shall have offered to the
         Trustee reasonable security or indemnity against the costs, expenses
         and liabilities which 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, in its discretion, may make such further inquiry or
         investigation into such facts or matters as it may see fit, and, if the
         Trustee shall determine to make such further inquiry or investigation,
         it shall be entitled to examine the books, records and premises of the
         Company, personally or by agent or attorney at the expense of the
         Company and shall incur no liability or additional 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; and

                  (g) 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 to each agent,
         custodian and other Person employed to act hereunder.

                                       67
<PAGE>

          Section 8.3 NO RESPONSIBILITY FOR RECITALS, Etc. The recitals
contained herein and in the Notes (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
Notes. The Trustee shall not be accountable for the use or application by the
Company of any Notes or the proceeds of any Notes authenticated and delivered by
the Trustee in conformity with the provisions of this Indenture.

          Section 8.4 TRUSTEE, PAYING AGENTS, CONVERSION AGENTS OR REGISTRAR MAY
OWN NOTES. The Trustee, any paying agent, any conversion agent or Note
registrar, in its individual or any other capacity, may become the owner or
pledgee of Notes with the same rights it would have if it were not Trustee,
paying agent, conversion agent or Note registrar.

          Section 8.5 MONIES TO BE HELD IN TRUST. Subject to the provisions of
Section 13.4 and Section 4.2, 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 8.6 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, reasonable 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 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 arise from its negligence or willful misconduct. The Company
also covenants to fully indemnify the Trustee (or

                                       68
<PAGE>

any officer, director or employee of the Trustee) and any predecessor 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, claim,
damage or expense (including taxes other than taxes based on the income of the
Trustee) incurred without negligence or willful misconduct 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 of
liability in the premises. The obligations of the Company under this Section 8.6
to compensate or indemnify the Trustee and to pay or reimburse the Trustee for
expenses, disbursements and advances shall be secured by a lien prior to that of
the Notes upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the benefit of the holders of particular Notes.
The obligation of the Company under this Section shall survive the resignation
or removal of the Trustee and the satisfaction and discharge of this Indenture.

          When the Trustee and its agents and any authenticating agent incur
expenses or render services after an Event of Default specified in Section
7.1(d) or (e) 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 8.7 OFFICERS' CERTIFICATE AS EVIDENCE. Except as otherwise
provided in Section 8.1, 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 negligence 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 8.8 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

                                       69
<PAGE>

extent and in the manner provided by, and subject to the provisions of, the
Trust Indenture Act and this Indenture.

          Section 8.9 ELIGIBILITY OF TRUSTEE. There shall at all times be a
Trustee hereunder which 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 8.9, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

          Section 8.10  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 Notes. 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,
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 the mailing of
such notice of resignation to the Noteholders, the resigning Trustee may, upon
ten (10) business days' notice to the Company and the Noteholders, 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 Noteholder who has been a bona fide holder of a Note or
Notes for at least six (6) months may, subject to the provisions of Section 7.9,
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.

                                       70
<PAGE>

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

                  (1) the Trustee shall fail to comply with Section 8.8 after
         written request therefor by the Company or by any Noteholder who has
         been a bona fide holder of a Note or Notes for at least six (6) months;
         or

                  (2) the Trustee shall cease to be eligible in accordance with
         the provisions of Section 8.9 and shall fail to resign after written
         request therefor by the Company or by any such Noteholder; or

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

then, in any such case, the Company may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors, 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 7.9, any Noteholder who has been a bona fide holder of a
Note or Notes 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,
however, that if no successor Trustee shall have been appointed and have
accepted appointment sixty (60) days after either the Company or the Noteholders
has removed the Trustee, the Trustee so removed may petition 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
Notes at the time outstanding may at any time remove the Trustee and nominate a
successor trustee which shall be deemed appointed as successor trustee 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 Noteholder, or if
such Trustee so

                                       71
<PAGE>

removed or any Noteholder fails to act, the Company, upon the terms and
conditions and otherwise as in Section 8.10(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 8.10 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 8.11.

          Section 8.11 ACCEPTANCE BY SUCCESSOR TRUSTEE. Any successor trustee
appointed as provided in Section 8.10 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 and its agents and counsel pursuant to
the provisions of Section 8.6, execute and deliver an instrument 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 Notes, to secure any amounts then due it
pursuant to the provisions of Section 8.6.

          No successor trustee shall accept appointment as provided in this
Section 8.11 unless, at the time of such acceptance, such successor trustee
shall be qualified under the provisions of Section 8.8 and be eligible under the
provisions of Section 8.9.

          Upon acceptance of appointment by a successor trustee as provided in
this Section 8.11, the Company (or the former trustee, at the expense of and at
the written direction of the Company) shall mail or cause to be mailed notice of
the succession of such trustee hereunder to the

                                       72
<PAGE>

holders of Notes at their addresses as they shall appear on the Note register.
If the Company fails to mail such notice within ten (10) 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 8.12 SUCCESSION BY MERGER, ETC. 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 8.8 and eligible
under the provisions of Section 8.9.

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

          Section 8.13 PREFERENTIAL COLLECTION OF CLAIMS. If and when the
Trustee shall be or become a creditor of the Company (or any other obligor upon
the Notes), 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 8.14 TRUSTEE'S APPLICATION FOR INSTRUCTIONS FROM THE COMPANY.
Any application by the Trustee for written instructions from the Company (other
than with regard to any action proposed to be taken or omitted to be taken by
the Trustee that affects the rights of the holders of the Notes or holders of
Senior Indebtedness under this Indenture, including, without limitation, under
Article Four hereof) may, at the option of the Trustee, set forth in writing any
action proposed to be taken or omitted by the Trustee under this Indenture and
the date on and/or after which such action shall be taken or such omission shall
be effective. The Trustee shall not be liable for any action taken by, or
omission of, the Trustee in accordance with a proposal included in such
application on or after the date specified in such application (which date shall
not be less than three (3) Business Days after the date any officer of the
Company actually receives such application, unless any such officer shall have
consented in writing to any earlier date) unless prior to taking any such action
(or the effective date in the case of an omission), the Trustee shall have
received written instructions in response to such application specifying the
action to be taken or omitted.

                                  ARTICLE NINE

                                 THE NOTEHOLDERS

          Section 9.1 ACTION BY NOTEHOLDERS. Whenever in this Indenture it is
provided that the holders of a specified percentage in aggregate principal
amount of the Notes 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 Noteholders
in person or by agent or proxy appointed in writing, or (b) by the record of the
holders of Notes voting in favor thereof at any meeting of Noteholders duly
called and held in accordance with the provisions of Article Ten, or (c) by a
combination of such instrument or instruments and any such record of such a
meeting of Noteholders. Whenever the Company or the Trustee solicits the taking
of any action by the holders of the Notes, 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

                                       74
<PAGE>

be not more than fifteen (15) days prior to the date of commencement of
solicitation of such action.

          Section 9.2 PROOF OF EXECUTION BY NOTEHOLDERS. Subject to the
provisions of Sections 8.1, 8.2 and 10.5, proof of the execution of any
instrument by a Noteholder 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 Notes shall be proved by the registry of such Notes or by a
certificate of the Note registrar.

          The record of any Noteholders' meeting shall be proved in the manner
provided in Section 10.6.

          Section 9.3 WHO ARE DEEMED ABSOLUTE OWNERS. The Company, the Trustee,
any paying agent, any conversion agent and any Note registrar may deem the
Person in whose name such Note shall be registered upon the Note register to be,
and may treat it as, the absolute owner of such Note (whether or not such Note
shall be overdue and notwithstanding any notation of ownership or other writing
thereon made by any Person other than the Company or any Note registrar) for the
purpose of receiving payment of or on account of the principal of, premium, if
any, and interest on such Note, for conversion of such Note and for all other
purposes; and neither the Company nor the Trustee nor any paying agent nor any
conversion agent nor any Note 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 Note.

          Section 9.4 COMPANY-OWNED NOTES DISREGARDED. In determining whether
the holders of the requisite aggregate principal amount of Notes have concurred
in any direction, consent, waiver or other action under this Indenture, Notes
which are owned by the Company or any other obligor on the Notes or any
Affiliate of the Company or any other obligor on the Notes shall be disregarded
and deemed not to be outstanding for the purpose of any such determination;
provided, however, that, for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, consent, waiver or other
action, only Notes which a Responsible Officer knows are so owned shall be so
disregarded. Notes so owned which have been pledged in good

                                       75
<PAGE>

faith may be regarded as outstanding for the purposes of this Section 9.4 if the
pledgee shall establish to the satisfaction of the Trustee the pledgee's right
to vote such Notes and that the pledgee is not the Company, any other obligor on
the Notes 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 Notes, 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 8.1, 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 Notes not listed therein are outstanding for the purpose of any
such determination.

          Section 9.5 REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND. At any time
prior to (but not after) the evidencing to the Trustee, as provided in Section
9.1, of the taking of any action by the holders of the percentage in aggregate
principal amount of the Notes specified in this Indenture in connection with
such action, any holder of a Note which is shown by the evidence to be included
in the Notes the holders of which have consented to such action may, by filing
written notice with the Trustee at its Corporate Trust Office and upon proof of
holding as provided in Section 9.2, revoke such action so far as concerns such
Note. Except as aforesaid, any such action taken by the holder of any Note shall
be conclusive and binding upon such holder and upon all future holders and
owners of such Note and of any Notes issued in exchange or substitution
therefor, irrespective of whether any notation in regard thereto is made upon
such Note or any Note issued in exchange or substitution therefor.

call a meeting of Noteholders to take any action specified in Section 10.1, to
be held at such time and at such place as the Trustee shall determine. Notice of

meeting and in general terms the action proposed to be taken at such meeting and
the establishment of any record date pursuant to Section 9.1, shall be mailed to
holders of Notes at their addresses as they shall appear on the Note register.
Such notice shall also be mailed to the Company. Such notices shall be mailed
not less than twenty (20) nor more than ninety (90) days prior to the date fixed
for the meeting.

          Any meeting of Noteholders shall be valid without notice if the
holders of all Notes then outstanding are present in person or by proxy or if
notice is waived before or after the meeting by the holders of all Notes
outstanding, and if the Company and the Trustee are either present by duly
authorized representatives or have, before or after the meeting, waived notice.

          Section 10.3 CALL OF MEETINGS BY COMPANY OR NOTEHOLDERS. In case at
any time the Company, pursuant to a resolution of its Board of Directors, or the
holders of at least ten percent (10%) in aggregate principal amount of the Notes

Noteholders, by written request setting forth in reasonable detail the action
proposed to be taken

                                       77
<PAGE>

within twenty (20) days after receipt of such request, then the Company or such
Noteholders may determine the time and the place for such meeting and may call
such meeting to take any action authorized in Section 10.1, by mailing notice
thereof as provided in Section 10.2.

          Section 10.4 QUALIFICATIONS FOR VOTING. To be entitled to vote at any
meeting of Noteholders a person shall (a) be a holder of one or more Notes on
the record date pertaining to such meeting or (b) be a person appointed by an
instrument in writing as proxy by a holder of one or more Notes on the record
date pertaining to such meeting. The only persons who shall be entitled to be
present or to speak at any meeting of Noteholders shall be the persons entitled
to vote at such meeting and their counsel and any representatives of the Trustee
and its counsel and any representatives of the Company and its counsel.

          Section 10.5 REGULATIONS. Notwithstanding any other provisions of this
Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Noteholders, in regard to proof of the holding of
Notes 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
chairman of the meeting, unless the meeting shall have been called by the
Company or by Noteholders as provided in Section 10.3, in which case the Company
or the Noteholders calling the meeting, as the case may be, shall in like manner
appoint a temporary chairman. A permanent chairman and a permanent secretary of
the meeting shall be elected by vote of the holders of a majority in principal
amount of the Notes represented at the meeting and entitled to vote at the
meeting.

          Subject to the provisions of Section 9.4, at any meeting each
Noteholder or proxyholder shall be entitled to one vote for each $1,000
principal amount of Notes held or represented by him; provided, however, that no
vote shall be cast or counted at any meeting in respect of any Note challenged
as not outstanding and ruled by the chairman of the meeting to be not
outstanding. The chairman of the meeting shall have no right to vote other than
by virtue of

                                       78
<PAGE>

the proxy to vote on behalf of other Noteholders. Any meeting of Noteholders
duly called pursuant to the provisions of Section 10.2 or 10.3 may be adjourned
from time to time by the holders of a majority of the aggregate principal amount
of Notes represented at the meeting, whether or not constituting a quorum, and
the meeting may be held as so adjourned without further notice.

meeting of Noteholders shall be by written ballot on which shall be subscribed
the signatures of the holders of Notes or of their representatives by proxy and
the outstanding principal amount of the Notes held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting. A record in duplicate of
the proceedings of each meeting of Noteholders shall be prepared by the
secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or more persons having knowledge of the facts setting forth a
copy of the notice of the meeting and showing that said notice was mailed as
provided in Section 10.2. The record shall show the principal amount of the
Notes voting in favor of or against any resolution. The record shall be signed
and verified by the affidavits of the 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
matters therein stated.

          Section 10.7 NO DELAY OF RIGHTS BY MEETING. Nothing contained in this
Article Ten shall be deemed or construed to authorize or permit, by reason of
any call of a meeting of Noteholders or any rights expressly or impliedly
conferred hereunder to make such call, any hindrance or delay in the exercise of
any right or rights conferred upon or reserved to the Trustee or to the
Noteholders under any of the provisions of this Indenture or of the Notes.

                             SUPPLEMENTAL INDENTURES

          Section 11.1 SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF NOTEHOLDERS.
The Company, 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 one or more of the following purposes:

                  (a) to make provision with respect to the conversion rights of
         the holders of Notes pursuant to the requirements of Section 15.6 and
         the redemption obligations of the Company pursuant to the requirements
         of Section 3.5(e);

                  (b) subject to Article Four, to convey, transfer, assign,
         mortgage or pledge to the Trustee as security for the Notes, any
         property or assets;

                  (c) to evidence the succession of another Person to the
         Company, or successive successions, and the assumption by the successor
         Person of the covenants, agreements and obligations of the Company
         pursuant to Article Twelve;

                  (d) to add to the covenants of the Company such further
         covenants, restrictions or conditions as the Board of Directors and the
         Trustee shall consider to be for the benefit of the holders of Notes,
         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, however, 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 shorter
         or longer than that allowed in the case of other defaults) or may
         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 Notes
         in coupon form (including Notes registrable as to principal only) and
         to provide for

                                       80
<PAGE>

         exchangeability of such Notes with the Notes issued hereunder in fully
         registered form and to make all appropriate changes for such purpose;

                  (f) to cure any ambiguity or to correct or supplement any
         provision contained herein or in any supplemental indenture that may be
         defective or inconsistent with any other provision contained herein or
         in any supplemental indenture, or to make such other provisions in
         regard to matters or questions arising under this Indenture that shall
         not materially adversely affect the interests of the holders of the
         Notes;

                  (g) to evidence and provide for the acceptance of appointment
         hereunder by a successor Trustee with respect to the Notes; or

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

          Upon the written request of the Company, accompanied by a copy of the
resolutions of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any supplemental indenture, the Trustee
is hereby authorized to join with the Company 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 11.1 may be executed by the Company and the Trustee without the consent
of the holders of any of the Notes at the time outstanding, notwithstanding any
of the provisions of Section 11.2.

          Notwithstanding any other provision of the Indenture or the Notes, the
Registration Rights Agreement and the obligation to pay Liquidated Damages
thereunder may

                                       81
<PAGE>

be amended, modified or waived in accordance with the provisions of the
Registration Rights Agreement.

          Section 11.2 SUPPLEMENTAL INDENTURE WITH CONSENT OF NOTEHOLDERS. With
the consent (evidenced as provided in Article Nine) of the holders of not less
than a majority in aggregate principal amount of the Notes at the time
outstanding, the Company, 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 adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or any supplemental indenture or of modifying in any manner the
rights of the holders of the Notes; provided, however, that no such supplemental
indenture shall (i) extend the fixed maturity of any Note, or reduce the rate or
extend the time of payment of interest thereon, or reduce the principal amount
thereof or premium, if any, thereon, or reduce any amount payable on redemption
thereof, or impair the right of any Noteholder to institute suit for the payment
thereof, or make the principal thereof or interest or premium, if any, thereon
payable in any coin or currency other than that provided in the Notes, or modify
the provisions of this Indenture with respect to the subordination of the Notes
in a manner adverse to the Noteholders in any material respect, or change the
obligation of the Company to redeem any Note upon the happening of a Fundamental
Change in a manner adverse to the holder of Notes, or impair the right to
convert the Notes into Common Stock subject to the terms set forth herein,
including Section 15.6, in each case, without the consent of the holder of each
Note so affected, or (ii) reduce the aforesaid percentage of Notes, the holders
of which are required to consent to any such supplemental indenture, without the
consent of the holders of all Notes then outstanding.

          Upon the written request of the Company, accompanied by a copy of the
resolutions of the Board of Directors certified by its Secretary or Assistant
Secretary and authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of Noteholders as
aforesaid, the Trustee shall join with the Company 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

                                       82
<PAGE>

in its discretion, but shall not be obligated to, enter into such supplemental
indenture.

          It shall not be necessary for the consent of the Noteholders under
this Section 11.2 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

          Section 11.3 EFFECT OF SUPPLEMENTAL INDENTURE. Any supplemental
indenture executed pursuant to the provisions of this Article Eleven shall
comply with the Trust Indenture Act, as then in effect, provided that this
Section 11.3 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 Eleven, 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 and the holders of Notes 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 11.4 NOTATION ON NOTES. Notes authenticated and delivered
after the execution of any supplemental indenture pursuant to the provisions of
this Article Eleven 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 Notes so modified as to conform, in the opinion
of the Trustee and the 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 the Trustee (or an
authenticating agent duly appointed by the Trustee pursuant to Section 16.11)
and delivered in exchange

                                       83
<PAGE>

for the Notes then outstanding, upon surrender of such Notes then outstanding.

          Section 11.5 EVIDENCE OF COMPLIANCE OF SUPPLEMENTAL INDENTURE TO BE
FURNISHED TO TRUSTEE. Prior to entering into any supplemental indenture, the
Trustee may request an Officers' Certificate and an Opinion of Counsel meeting
the requirements set forth in Section 16.5 as conclusive evidence that any
supplemental indenture executed pursuant hereto complies with the requirements
of this Article Eleven.

                                 ARTICLE TWELVE

                CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

          Section 12.1 COMPANY MAY CONSOLIDATE, ETC., ON CERTAIN TERMS. Subject
to the provisions of Section 12.2, nothing contained in this Indenture or in any
of the Notes shall prevent any consolidation or merger of the Company with or
into any other Person or Persons (whether or not affiliated with the Company),
or successive consolidations or mergers in which the Company or its successor or
successors shall be a party or parties, or shall prevent any sale, conveyance or
lease (or successive sales, conveyances or leases) of all or substantially all
of the property of the Company, to any other Person (whether or not affiliated
with the Company), authorized to acquire and operate the same and that shall be
organized under the laws of the United States of America, any state thereof or
the District of Columbia; provided, however, that upon any such consolidation,
merger, sale, conveyance or lease, the due and punctual payment of the principal
of and premium, if any, and interest (including Liquidated Damages, if any) on
all of the Notes, according to their tenor and the due and punctual performance
and observance of all of the covenants and conditions of this Indenture to be
performed by the Company, shall be expressly assumed, by supplemental indenture
satisfactory in form to the Trustee, executed and delivered to the Trustee by
the Person (if other than the Company) formed by such consolidation, or into
which the Company shall have been merged, or by the Person that shall have
acquired or leased such property, and such supplemental indenture shall provide
for the applicable conversion rights set forth in Section 15.6.

          Section 12.2 SUCCESSOR CORPORATION TO BE SUBSTITUTED. In case of any
such consolidation, merger,

                                       84
<PAGE>

sale, conveyance or lease and 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 due and punctual payment of the principal of and
premium, if any, and interest on all of the Notes and the due and punctual
performance of all of the covenants and conditions of this Indenture to be
performed by the Company, such successor Person shall succeed to and be
substituted for the Company, with the same effect as if it had been named herein
as the party of this first part. Such successor Person thereupon may cause to be
signed, and may issue either in its own name or in the name of Conexant Systems,
Inc. any or all of the Notes, issuable hereunder that theretofore shall not have
been signed by the Company and delivered to the Trustee; and, upon the order of
such successor Person instead of the Company 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
Notes that previously shall have been signed and delivered by the officers of
the Company to the Trustee for authentication, and any Notes that such successor
Person thereafter shall cause to be signed and delivered to the Trustee for that
purpose. All the Notes so issued shall in all respects have the same legal rank
and benefit under this Indenture as the Notes theretofore or thereafter issued
in accordance with the terms of this Indenture as though all of such Notes had
been issued at the date of the execution hereof. In the event of any such
consolidation, merger, sale, conveyance or lease, the Person named as the
"Company" in the first paragraph of this Indenture or any successor that shall
thereafter have become such in the manner prescribed in this Article Twelve may
be dissolved, wound up and liquidated at any time thereafter and such Person
shall be released from its liabilities as obligor and maker of the Notes and
from its obligations under this Indenture.

          In case of any such consolidation, merger, sale, conveyance or lease,
such changes in phraseology and form (but not in substance) may be made in the
Notes thereafter to be issued as may be appropriate.

          Section 12.3 OPINION OF COUNSEL TO BE GIVEN TRUSTEE. The Trustee shall
receive an Officers' Certificate and an Opinion of Counsel as conclusive
evidence that any such consolidation, merger, sale, conveyance or lease and any
such assumption complies with the provisions of this Article Twelve.

in substitution for which other Notes shall have been authenticated and
delivered) and not theretofore canceled, or (b) all the Notes not theretofore
canceled or delivered to the Trustee for cancellation shall have become due and
payable, or are by their terms to become due and payable within one year or are
to be called for redemption within one year under arrangements satisfactory to
the Trustee for the giving of notice of redemption, and the Company shall
deposit with the Trustee, in trust, funds sufficient to pay at maturity or upon

canceled or delivered to the Trustee for cancellation, including principal and
premium, if any, and interest due or to become due to such date of maturity or

the sufficiency of the deposited amount, from an independent certified
accountant or other financial professional satisfactory to the Trustee, and if
the Company shall also pay or cause to be paid all other sums payable hereunder
by the Company, then this Indenture shall cease to be of further effect (except
as to (i) remaining rights of registration of transfer, substitution and
exchange and conversion of Notes, (ii) rights hereunder of Noteholders to
receive payments of principal of and premium, if any, and interest on, the Notes
and the other rights, duties and obligations of Noteholders, as beneficiaries
hereof with respect to the amounts, if any, so deposited with the Trustee and
(iii) the rights, obligations and immunities of the Trustee hereunder), and the
Trustee, on written demand of the Company accompanied by an Officers'
Certificate and an Opinion of Counsel as required by Section 16.5 and at the
cost and expense of the Company, shall execute proper instruments acknowledging
satisfaction of and discharging this Indenture; the Company, however, hereby
agrees to reimburse the Trustee for any costs or expenses thereafter reasonably
and properly incurred by the Trustee and to compensate the Trustee for any
services thereafter

                                       86

reasonably and properly rendered by the Trustee in connection with this
Indenture or the Notes.

to Section 13.4, all monies deposited with the Trustee pursuant to Section 13.1,
provided such deposit was not in violation of Article Four, shall be held in
trust for the sole benefit of the Noteholders and not to be subject to the
subordination provisions of Article Four, and such monies shall be applied by
the Trustee to the payment, either directly or through any paying agent
(including the Company if acting as its own paying agent), to the holders of the
particular Notes for the payment or redemption of which such monies have been
deposited with the Trustee, of all sums due and to become due thereon for
principal and interest and premium, if any.

          Section 13.3 PAYING AGENT TO REPAY MONIES HELD. Upon the satisfaction
and discharge of this Indenture, all monies then held by any paying agent of the
Notes (other than the Trustee) shall, upon written request of the Company, be
repaid to it or paid to the Trustee, and thereupon such paying agent shall be
released from all further liability with respect to such monies.

          Section 13.4 RETURN OF UNCLAIMED MONIES. Subject to the requirements
of applicable law, any monies deposited with or paid to the Trustee for payment
of the principal of, premium, if any, or interest on Notes and not applied but
remaining unclaimed by the holders of Notes for two years after the date upon
which the principal of, premium, if any, or interest on such Notes, as the case
may be, shall have become due and payable, shall be repaid to the Company by the
Trustee on demand and all liability of the Trustee shall thereupon cease with
respect to such monies; and the holder of any of the Notes shall thereafter look
only to the Company for any payment that such holder may be entitled to collect
unless an applicable abandoned property law designates another Person.

          Section 13.5 REINSTATEMENT. If the Trustee or the paying agent is
unable to apply any money in accordance with Section 13.2 by reason of any order
or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 13.1 until such time as the Trustee or

                                       87
<PAGE>

the paying agent is permitted to apply all such money in accordance with Section
13.2; provided, however, that if the Company makes any payment of interest on or
principal of any Note following the reinstatement of its obligations, the
Company shall be subrogated to the rights of the holders of such Notes to
receive such payment from the money held by the Trustee or paying agent.

                                ARTICLE FOURTEEN

                           IMMUNITY OF INCORPORATORS,
                      STOCKHOLDERS, OFFICERS AND DIRECTORS

          Section 14.1 INDENTURE AND NOTES SOLELY CORPORATE OBLIGATIONS. No
recourse for the payment of the principal of or premium, if any, or interest on
any Note, 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 in
this Indenture or in any supplemental indenture or in any Note, 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; 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 Notes.

                                 ARTICLE FIFTEEN

                               CONVERSION OF NOTES

          Section 15.1 RIGHT TO CONVERT. Subject to and upon compliance with the
provisions of this Indenture, including, without limitation, Article Four, the
holder of any Note shall have the right, at its option, at any time after the
original issuance of the Notes hereunder through the close of business on the
final maturity date of the Notes (except that, with respect to any Note or
portion of a Note that shall be called for redemption, such right shall
terminate, except as provided in Section 15.2, Section 3.2 or Section 3.4, at
the close of business on the Business Day next preceding the date fixed for
redemption of such Note or portion of a Note unless the Company shall default in

                                       88
<PAGE>

payment due upon redemption thereof) to convert the principal amount of any such
Note, or any portion of such principal amount which is $1,000 or an integral
multiple thereof, into that number of fully paid and non-assessable shares of
Common Stock (as such shares shall then be constituted) obtained by dividing the
principal amount of the Note or portion thereof surrendered for conversion by
the Conversion Price in effect at such time, by surrender of the Note so to be
converted in whole or in part in the manner provided, together with any required
funds, in Section 15.2. A Note in respect of which a holder is exercising its
option to require redemption upon a Fundamental Change pursuant to Section 3.5
may be converted only if such holder withdraws its election to exercise in
accordance with Section 3.5. A holder of Notes is not entitled to any rights of
a holder of Common Stock until such holder has converted his Notes to Common
Stock, and only to the extent such Notes are deemed to have been converted to
Common Stock under this Article Fifteen.

          Section 15.2 EXERCISE OF CONVERSION PRIVILEGE; ISSUANCE OF COMMON
STOCK ON CONVERSION; NO ADJUSTMENT FOR INTEREST OR DIVIDENDS. In order to
exercise the conversion privilege with respect to any Note in certificated form,
the holder of any such Note to be converted in whole or in part shall surrender
such Note, duly endorsed, at an office or agency maintained by the Company
pursuant to Section 5.2, accompanied by the funds, if any, required by the
penultimate paragraph of this Section 15.2, and shall give written notice of
conversion in the form provided on the Notes (or such other notice which is
acceptable to the Company) to the office or agency that the holder elects to
convert such Note or the portion thereof specified in said notice. Such notice
shall also state the name or names (with address or addresses) in which the
certificate or certificates for shares of Common Stock which shall be issuable
on such conversion shall be issued, and shall be accompanied by transfer taxes,
if required pursuant to Section 15.7. Each such Note surrendered for conversion
shall, unless the shares issuable on conversion are to be issued in the same
name as the registration of such Note, be duly endorsed by, or be accompanied by
instruments of transfer in form satisfactory to the Company duly executed by,
the holder or his duly authorized attorney.

          In order to exercise the conversion privilege with respect to any
interest in a Note in global form, the beneficial holder must complete, or cause
to be completed,

                                       89
<PAGE>

the appropriate instruction form for conversion pursuant to the Depository's
book-entry conversion program, deliver, or cause to be delivered, by book-entry
delivery an interest in such Note in global form, furnish appropriate
endorsements and transfer documents if required by the Company or the Trustee or
conversion agent, and pay the funds, if any, required by this Section 15.2 and
any transfer taxes if required pursuant to Section 15.7.

          As promptly as practicable after satisfaction of the requirements for
conversion set forth above, subject to compliance with any restrictions on
transfer if shares issuable on conversion are to be issued in a name other than
that of the Noteholder (as if such transfer were a transfer of the Note or Notes
(or portion thereof) so converted), the Company shall issue and shall deliver to
such Noteholder at the office or agency maintained by the Company for such
purpose pursuant to Section 5.2, a certificate or certificates for the number of
full shares of Common Stock issuable upon the conversion of such Note or portion
thereof as determined by the Company in accordance with the provisions of this
Article Fifteen and a check or cash in respect of any fractional interest in
respect of a share of Common Stock arising upon such conversion, calculated by
the Company as provided in Section 15.3. In case any Note of a denomination
greater than $1,000 shall be surrendered for partial conversion, and subject to
Section 2.3, the Company shall execute and the Trustee shall authenticate and
deliver to the holder of the Note so surrendered, without charge to him, a new
Note or Notes in authorized denominations in an aggregate principal amount equal
to the unconverted portion of the surrendered Note.

          Each conversion shall be deemed to have been effected as to any such
Note (or portion thereof) on the date on which the requirements set forth above
in this Section 15.2 have been satisfied as to such Note (or portion thereof),
and the Person in whose name any certificate or certificates for shares of
Common Stock shall be issuable upon such conversion shall be deemed to have
become on said date the holder of record of the shares represented thereby;
provided, however, that any such surrender on any date when the stock transfer
books of the Company shall be closed shall constitute the Person in whose name
the certificates are to be issued as the record holder thereof for all purposes
on the next succeeding day on which such stock transfer books are open, but such
conversion shall be at the

                                       90
<PAGE>

Conversion Price in effect on the date upon which such Note shall be
surrendered.

          No adjustment in respect of interest on any Note converted or
dividends on any shares issued upon conversion of such Note will be made upon
any conversion except as set forth in the next sentence. If this Note (or
portion hereof) is surrendered for conversion during the period from the close
of business on any record date for the payment of interest to the close of
business on the Business Day preceding the following interest payment date and
either (x) has not been called for redemption on a redemption date that occurs
during such period or (y) is not to be redeemed in connection with a Fundamental
Change on a Repurchase Date that occurs during such period, this Note (or
portion hereof being converted) must be accompanied by an amount, in New York
Clearing House funds or other funds acceptable to the Company, equal to the
interest payable on such interest payment date on the principal amount being
converted; provided, however, that no such payment shall be required if there
shall exist at the time of conversion a default in the payment of interest on
the Notes.

          Upon the conversion of an interest in a Note in global form, the
Trustee (or other conversion agent appointed by the Company), or the Custodian
at the direction of the Trustee (or other conversion agent appointed by the
Company), shall make a notation on such Note in global form as to the reduction
in the principal amount represented thereby. The Company shall notify the
Trustee in writing of any conversions of Notes effected through any conversion
agent other than the Trustee.

          Section 15.3 CASH PAYMENTS IN LIEU OF FRACTIONAL SHARES. No fractional
shares of Common Stock or scrip representing fractional shares shall be issued
upon conversion of Notes. If more than one Note shall be surrendered for
conversion at one time by the same holder, the number of full shares that shall
be issuable upon conversion shall be computed on the basis of the aggregate
principal amount of the Notes (or specified portions thereof to the extent
permitted thereby) so surrendered. If any fractional share of stock would be
issuable upon the conversion of any Note or Notes, the Company shall make an
adjustment and payment therefor in cash at the current market price thereof to
the holder of Notes. The current market price of a share of Common Stock shall
be the Closing Price on the last Business Day immediately preceding the day

                                       91
<PAGE>

on which the Notes (or specified portions thereof) are deemed to have been
converted.

          Section 15.4 CONVERSION PRICE. The conversion price shall be as
specified in the form of Note (herein called the "Conversion Price") attached as
Exhibit A hereto, subject to adjustment as provided in this Article Fifteen.

          Section 15.5 ADJUSTMENT OF CONVERSION PRICE. The Conversion Price
shall be adjusted from time to time 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 Price shall be reduced so that the same
         shall equal the price determined by multiplying the Conversion Price in
         effect at the opening of business on the date following the date fixed
         for the determination of stockholders entitled to receive such dividend
         or other distribution by a fraction, the numerator of which shall be
         the number of shares of the Common Stock outstanding at the close of
         business on the date fixed for such determination, and the denominator
         of which shall be the sum of such number of shares and the total number
         of shares constituting such dividend or other distribution, such
         reduction to become effective immediately after the opening of business
         on the day following the date fixed for such determination. For the
         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 in the treasury of the
         Company. If any dividend or distribution of the type described in this
         Section 15.5(a) is declared but not so paid or made, the Conversion
         Price shall again be adjusted to the Conversion Price that would then
         be in effect if such dividend or distribution had not been declared.

                  (b) In case the Company shall issue rights 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 or
         warrants) to subscribe for or purchase shares of Common Stock at a
         price per share less than the

                                       92
<PAGE>

         Current Market Price (as defined below) on the date fixed for
         determination of stockholders entitled to receive such rights or
         warrants, the Conversion Price shall be adjusted so that the same shall
         equal the price determined by multiplying the Conversion Price in
         effect immediately prior to the date fixed for determination of
         stockholders entitled to receive such rights or warrants by a fraction,
         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 or
         warrants plus the number of shares that the aggregate offering price of
         the total number of shares so offered would purchase at such Current
         Market Price, and the denominator of which shall be the number of
         shares of Common Stock outstanding on the date fixed for determination
         of stockholders entitled to receive such rights or warrants plus the
         total number of additional shares of Common Stock offered for
         subscription or purchase. Such adjustment shall be successively made
         whenever any such rights 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 or warrants. To the extent that shares of Common
         Stock are not delivered after the expiration of such rights or
         warrants, the Conversion Price shall be readjusted to the Conversion
         Price that would then be in effect had the adjustments made upon the
         issuance of such rights or warrants been made on the basis of delivery
         of only the number of shares of Common Stock actually delivered. In the
         event that such rights or warrants are not so issued, the Conversion
         Price shall again be adjusted to be the Conversion Price that would
         then be in effect if such date fixed for the determination of
         stockholders entitled to receive such rights or warrants had not been
         fixed. In determining whether any rights or warrants entitle the
         holders to subscribe for or purchase shares of Common Stock at less
         than such Current Market Price, 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
         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.

                                       93
<PAGE>

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

                  (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 (other than any dividends or distributions
         to which Section 15.5(a) applies) or evidences of its indebtedness or
         assets (including securities, but excluding any rights or warrants
         referred to in Section 15.5(b), and excluding any dividend or
         distribution (x) paid exclusively in cash or (y) referred to in Section
         15.5(a) (any of the foregoing hereinafter in this Section 15.5(d)
         called the "Securities")), then, in each such case (unless the Company
         elects to reserve such Securities for distribution to the Noteholders
         upon the conversion of the Notes so that any such holder converting
         Notes will receive upon such conversion, in addition to the shares of
         Common Stock to which such holder is entitled, the amount and kind of
         such Securities which such holder would have received if such holder
         had converted its Notes into Common Stock immediately prior to the
         Record Date (as defined in Section 15.5(h)(4) for such distribution of
         the Securities)), the Conversion Price shall be reduced so that the
         same shall be equal to the price determined by multiplying the
         Conversion Price in effect on the Record Date with respect to such
         distribution by a fraction, the numerator of which shall be the Current
         Market Price per share of the Common Stock on such Record Date less the
         fair market value (as determined by the Board of Directors, whose
         determination shall be conclusive, and described in a resolution of the
         Board of Directors) on the Record Date of the portion of the Securities
         so distributed applicable to one share of

                                       94
<PAGE>

         Common Stock and the denominator of which shall be the Current Market
         Price per share of the Common Stock, such reduction to become effective
         immediately prior to the opening of business on the day following such
         Record Date; provided, however, that in the event the then fair market
         value (as so determined) of the portion of the Securities so
         distributed applicable to one share of Common Stock is equal to or
         greater than the Current Market Price of the Common Stock on the Record
         Date, in lieu of the foregoing adjustment, adequate provision shall be
         made so that each Noteholder shall have the right to receive upon
         conversion the amount of Securities such holder would have received had
         such holder converted each Note on the Record Date. In the event that
         such dividend or distribution is not so paid or made, the Conversion
         Price shall again be adjusted to be the Conversion Price that would
         then be in effect if such dividend or distribution had not been
         declared. If the Board of Directors determines the fair market value of
         any distribution for purposes of this Section 15.5(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 of the Common Stock.

                  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 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 15.5 (and no adjustment to the Conversion
         Price under this Section 15.5 will be required) until the occurrence of
         the earliest Trigger Event, whereupon such rights and warrants shall be
         deemed to have been distributed and an appropriate adjustment (if any
         is required) to the Conversion Price shall be made under this Section
         15.5(d). If any such right or warrant, including any such existing
         rights or warrants distributed prior to the date of this Indenture, are
         subject to events, upon the occurrence of which such rights or warrants
         become exercisable to purchase different securities, evidences

                                       95
<PAGE>

         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 or warrants with such rights
         (and a termination or expiration of the existing rights or warrants
         without exercise by any of the holders thereof). In addition, in the
         event of any distribution (or deemed distribution) of rights 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 Price under this Section 15.5 was made, (1) in the
         case of any such rights or warrants that shall all have been redeemed
         or repurchased without exercise by any holders thereof, the Conversion
         Price 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 or warrants (assuming such
         holder had retained such rights 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 or warrants that shall have expired or been
         terminated without exercise by any holders thereof, the Conversion
         Price shall be readjusted as if such rights and warrants had not been
         issued.

                  No adjustment of the Conversion Price shall be made pursuant
         to this Section 15.5(d) in respect of rights or warrants distributed or
         deemed distributed on any Trigger Event to the extent that such rights
         or warrants are actually distributed, or reserved by the Company for
         distribution to holders of Notes upon conversion by such holders of
         Notes to Common Stock.

                  For purposes of this Section 15.5(d) and Sections 15.5(a) and
         (b), any dividend or distribution to which this Section 15.5(d) is
         applicable that also includes shares of Common Stock, or rights 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 or warrants (and any Conversion
         Price reduction required by this Section 15.5(d) with

                                       96
<PAGE>

         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 or warrants (and any further Conversion
         Price reduction required by Sections 15.5(a) and (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 or
         warrants" and "the date fixed for such determination" within the
         meaning of Sections 15.5(a) and (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 such
         determination" within the meaning of Section 15.5(a).

                  (e) In case the Company shall, by dividend or otherwise,
         distribute to all holders of its Common Stock cash (excluding (x) any
         quarterly cash dividend on the Common Stock to the extent the aggregate
         cash dividend per share of Common Stock in any fiscal quarter does not
         exceed the greater of (A) the amount per share of Common Stock of the
         next preceding quarterly cash dividend on the Common Stock to the
         extent that such preceding quarterly dividend did not require any
         adjustment of the Conversion Price pursuant to this Section 15.5(e) (as
         adjusted to reflect subdivisions, or combinations of the Common Stock),
         and (B) 3.75% of the arithmetic average of the Closing Price
         (determined as set forth in Section 15.5(h)) during the ten Trading
         Days (as defined in Section 15.5(h)) immediately prior to the date of
         declaration of such dividend, and (y) 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 Price shall be reduced so that the same shall equal the
         price determined by multiplying the Conversion Price in effect
         immediately prior to the close of business on such record date by a
         fraction, the numerator of which shall be the Current Market Price of
         the Common Stock on the record date less the amount of cash so
         distributed (and not excluded as provided above) applicable to one
         share of Common Stock, and the denominator of which shall be such
         Current Market Price

                                       97

         of the Common Stock, such reduction to be effective immediately prior
         to the opening of business on the day following the record date;
         provided, however, that in the event the portion of the cash so
         distributed applicable to one share of Common Stock is equal to or
         greater than the Current Market Price of the Common Stock on the record
         date, in lieu of the foregoing adjustment, adequate provision shall be
         made so that each Noteholder shall have the right to receive upon
         conversion the amount of cash such holder would have received had such
         holder converted each Note on the record date. In the event that such
         dividend or distribution is not so paid or made, the Conversion Price
         shall again be adjusted to be the Conversion Price that would then be
         in effect if such dividend or distribution had not been declared. If
         any adjustment is required to be made as set forth in this Section
         15.5(e) as a result of a distribution that is a quarterly dividend,
         such adjustment shall be based upon the amount by which such
         distribution exceeds the amount of the quarterly cash dividend
         permitted to be excluded pursuant hereto. If an adjustment is required
         to be made as set forth in this Section 15.5(e) above as a result of a
         distribution that is not a quarterly dividend, such adjustment shall be
         based upon the full amount of the distribution.

                  (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, 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 Current Market Price of the Common Stock on the Trading Day
         next succeeding the Expiration Time, the Conversion Price shall be
         reduced so that the same shall equal the price determined by
         multiplying the Conversion Price in effect immediately prior to the
         Expiration Time by a fraction the numerator 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 Current
         Market Price of the Common

                                       98
<PAGE>

         Stock on the Trading Day next succeeding the Expiration Time and the
         denominator 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
         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 Current Market Price of the Common Stock on the Trading
         Day next succeeding the Expiration Time, such reduction to become
         effective immediately prior to the opening of business on the Trading
         Day following the Expiration Time. In the event that 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 Price shall again be adjusted to be the Conversion Price
         that would then be in effect if such tender or exchange offer had not
         been made.

                  (g) In case of a tender or exchange offer made by a Person
         other than the Company or any Subsidiary for an amount that increases
         the offeror's ownership of Common Stock to more than twenty-five
         percent (25%) of the Common Stock outstanding and shall involve the
         payment by such Person of consideration per share of Common Stock
         having a fair market value (as determined by the Board of Directors,
         whose determination shall be conclusive, and described in a resolution
         of the Board of Directors) that as of the last time (the "Offer
         Expiration Time") tenders or exchanges may be made pursuant to such
         tender or exchange offer (as it shall have been amended) that exceeds
         the Current Market Price of the Common Stock on the Trading Day next
         succeeding the Offer Expiration Time, and in which, as of the Offer
         Expiration Time the Board of Directors is not recommending rejection of
         the offer, the Conversion Price shall be reduced so that the same shall
         equal the price determined by multiplying the Conversion Price in
         effect immediately prior to the Offer Expiration Time by a fraction the
         numerator of which shall be the number of shares of Common Stock
         outstanding (including any tendered or exchanged shares) at the Offer

                                       99
<PAGE>

         Expiration Time multiplied by the Current Market Price of the Common
         Stock on the Trading Day next succeeding the Offer Expiration Time and
         the denominator 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 Offer Expiration Time
         (the shares deemed so accepted, up to any such maximum, being referred
         to as the "Accepted Purchased Shares") and (y) the product of the
         number of shares of Common Stock outstanding (less any Accepted
         Purchased Shares) at the Offer Expiration Time and the Current Market
         Price of the Common Stock on the Trading Day next succeeding the Offer
         Expiration Time, such reduction to become effective immediately prior
         to the opening of business on the Trading Day following the Offer
         Expiration Time. In the event that such Person is obligated to purchase
         shares pursuant to any such tender or exchange offer, but such Person
         is permanently prevented by applicable law from effecting any such
         purchases or all such purchases are rescinded, the Conversion Price
         shall again be adjusted to be the Conversion Price that would then be
         in effect if such tender or exchange offer had not been made.
         Notwithstanding the foregoing, the adjustment described in this Section
         15.5(g) shall not be made if, as of the Offer Expiration Time, the
         offering documents with respect to such offer disclose a plan or
         intention to cause the Company to engage in any transaction described
         in Article Twelve.

                  (h) For purposes of this Section 15.5, the following terms
         shall have the meaning indicated:

                           (1) "Closing Price" with respect to any security on
                  any day shall mean the closing sale price, regular way, on
                  such day or, in case no such sale takes place on such day, the
                  average of the reported closing bid and asked prices, regular
                  way, in each case as quoted on the Nasdaq National Market or,
                  if such security is not quoted or listed or admitted to
                  trading on such Nasdaq National Market, on the principal
                  national securities exchange or quotation system on which such
                  security is quoted or listed or admitted to trading or, if not
                  quoted or listed or admitted to

                                      100
<PAGE>

                  trading on any national securities exchange or quotation
                  system, the average of the closing bid and asked prices of
                  such security on the over-the-counter market on the day in
                  question as reported by the National Quotation Bureau
                  Incorporated, or a similar generally accepted reporting
                  service, or if not so available, in such manner as furnished
                  by any New York Stock Exchange member firm selected from time
                  to time by the Board of Directors for that purpose, or a price
                  determined in good faith by the Board of Directors or, to the
                  extent permitted by applicable law, a duly authorized
                  committee thereof, whose determination shall be conclusive.

                           (2) "Current Market Price" shall mean the average of
                  the daily Closing Prices per share of Common Stock for the ten
                  consecutive Trading Days immediately prior to the date in
                  question except as hereinafter provided for purposes of any
                  computation under Section 15.5(f) or (g); provided, however,
                  that (1) if the "ex" date (as hereinafter defined) for any
                  event (other than the issuance or distribution requiring such
                  computation and other than the tender or exchange offer
                  requiring such computation under Section 15.5(f) or (g)) that
                  requires an adjustment to the Conversion Price pursuant to
                  Section 15.5(a), (b), (c), (d), (e), (f) or (g) occurs during
                  such ten consecutive Trading Days, the Closing Price for each
                  Trading Day prior to the "ex" date for such other event shall
                  be adjusted by multiplying such Closing Price by the same
                  fraction by which the Conversion Price is so required to be
                  adjusted as a result of such other event, (2) if the "ex" date
                  for any event (other than the issuance or distribution
                  requiring such computation and other than the tender or
                  exchange offer requiring such computation under Section
                  15.5(f) or (g)) that requires an adjustment to the Conversion
                  Price pursuant to Section 15.5(a), (b), (c), (d), (e), (f) or
                  (g) occurs on or after the "ex" date for the issuance or
                  distribution requiring such computation and prior to the day
                  in question, the Closing Price for each Trading Day on and
                  after the "ex" date for such other event shall be adjusted by
                  multiplying such Closing Price by the reciprocal of the
                  fraction by which the Conversion

                                      101
<PAGE>

                  Price is so required to be adjusted as a result of such other
                  event, and (3) if the "ex" date for the issuance or
                  distribution requiring such computation is prior to the day in
                  question, after taking into account any adjustment required
                  pursuant to clause (1) or (2) of this proviso, the Closing
                  Price for each Trading Day on or after such "ex" date shall be
                  adjusted by adding thereto the amount of any cash and the fair
                  market value (as determined by the Board of Directors or, to
                  the extent permitted by applicable law, a duly authorized
                  committee thereof in a manner consistent with any
                  determination of such value for purposes of Section 15.5(d),
                  (f) or (g), whose determination shall be conclusive and
                  described in a resolution of the Board of Directors or such
                  duly authorized committee thereof, as the case may be) of the
                  evidences of indebtedness, shares of capital stock or assets
                  being distributed applicable to one share of Common Stock as
                  of the close of business on the day before such "ex" date. For
                  purposes of any computation under Section 15.5(f) or (g), the
                  "Current Market Price" of the Common Stock on any date shall
                  be deemed to be the average of the daily Closing Prices per
                  share of Common Stock for such day and the next two succeeding
                  Trading Days; provided, however, that if the "ex" date for any
                  event (other than the tender or exchange offer requiring such
                  computation under Section 15.5(f) or (g)) that requires an
                  adjustment to the Conversion Price pursuant to Section
                  15.5(a), (b), (c), (d), (e), (f) or (g) occurs on or after the
                  Expiration Time or Offer Expiration Time, as the case may be,
                  for the tender or exchange offer requiring such computation
                  and prior to the day in question, the Closing Price for each
                  Trading Day on and after the "ex" date for such other event
                  shall be adjusted as provided in clauses (1), (2) and (3) of
                  the proviso contained in the first sentence of this Section
                  15.5(h)(2). For purpose of this paragraph, the term "ex" date,
                  (1) when used with respect to any issuance or 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 issuance or distribution, (2) when used with

                                      102
<PAGE>

                  respect to any subdivision or combination of shares of Common
                  Stock, means the first date on which the Common Stock trades,
                  regular way, on such exchange or in such market after the time
                  at which such subdivision or combination becomes effective,
                  and (3) when used with respect to any tender or exchange offer
                  means the first date on which the Common Stock trades, regular
                  way, on such exchange or in such market after the Expiration
                  Time or the Offer Expiration Time of such offer.

                           (3) "fair market value" shall mean the amount which a
                  willing buyer would pay a willing seller in an arm's-length
                  transaction.

                           (4) "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 or by
                  statute, contract or otherwise).

                           (5) "Trading Day" shall mean (x) if the applicable
                  security is quoted on the Nasdaq National Market, a day on
                  which trades may be made thereon or (y) 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 (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.

                  (i) The Company may make such reductions in the Conversion
         Price, in addition to those required by Sections 15.5(a), (b), (c),
         (d), (e), (f) or (g) as the Board of Directors considers to be
         advisable to avoid

                                      103
<PAGE>

         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 reduce the Conversion Price by any amount for any
         period of time if the period is at least twenty (20) days, the
         reduction is irrevocable during the period and the Board of Directors
         shall have made a determination that such reduction would be in the
         best interests of the Company, which determination shall be conclusive.
         Whenever the Conversion Price is reduced pursuant to the preceding
         sentence, the Company shall mail to holders of record of the Notes a
         notice of the reduction at least fifteen (15) days prior to the date
         the reduced Conversion Price takes effect, and such notice shall state
         the reduced Conversion Price and the period during which it will be in
         effect.

                  (j) No adjustment in the Conversion Price shall be required
         unless such adjustment would require an increase or decrease of at
         least one percent (1%) in such price; provided, however, that any
         adjustments that by reason of this Section 15.5(j) are not required to
         be made shall be carried forward and taken into account in any
         subsequent adjustment. All calculations under this Article Fifteen
         shall be made by the Company and shall be made to the nearest cent or
         to the nearest one-hundredth (1/100) 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. To the extent
         the Notes become convertible into cash, assets, property or securities
         (other than capital stock of the Company), no adjustment need be made
         thereafter as to the cash, assets, property or such securities.
         Interest will not accrue on the cash.

                  (k) Whenever the Conversion Price 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 Price after such adjustment and setting
         forth a brief statement of the facts requiring such adjustment. Unless
         and until a Responsible Officer of

                                      104
<PAGE>

         the Trustee shall have received such Officers' Certificate, the Trustee
         shall not be deemed to have knowledge of any adjustment of the
         Conversion Price and may assume without inquiry that the last
         Conversion Price 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 Price setting forth the adjusted
         Conversion Price and the date on which each adjustment becomes
         effective and shall mail such notice of such adjustment of the
         Conversion Price to the holder of each Note at his last address
         appearing on the Note register provided for in Section 2.5 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.

                  (l) In any case in which this Section 15.5 provides that an
         adjustment shall become effective immediately after (1) a record date
         or Record Date for an event, (2) the date fixed for the determination
         of stockholders entitled to receive a dividend or distribution pursuant
         to Section 15.5(a), (3) a date fixed for the determination of
         stockholders entitled to receive rights or warrants pursuant to Section
         15.5(b), (4) the Expiration Time for any tender or exchange offer
         pursuant to Section 15.5(f), or (5) the Offer Expiration Time for a
         tender or exchange offer pursuant to Section 15.5(g) (each a
         "Determination Date"), the Company may elect to defer until the
         occurrence of the relevant Adjustment Event (as hereinafter defined)
         (x) issuing to the holder of any Note converted after such
         Determination Date and before the occurrence of such Adjustment Event,
         the additional shares of Common Stock or other securities issuable upon
         such conversion by reason of the adjustment required by such Adjustment

         before giving effect to such adjustment and (y) paying to such holder

         For purposes of this Section 15.5(l), the term "Adjustment Event" shall
         mean:

                           (a) in any case referred to in clause (1) hereof, the
                  occurrence of such event,

                                      105
<PAGE>

                           (b) in any case referred to in clause (2) hereof, the
                  date any such dividend or distribution is paid or made,

                           (c) in any case referred to in clause (3) hereof, the
                  date of expiration of such rights or warrants, and

                           (d) in any case referred to in clause (4) or clause
                  (5) hereof, the date a sale or exchange of Common Stock
                  pursuant to such tender or exchange offer is consummated and
                  becomes irrevocable.

                  (m) For purposes of this Section 15.5, 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 15.6 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 subdivision or
combination to which Section 15.5(c) applies), (ii) any consolidation, merger or
combination of the Company with another Person as a result of which holders of
Common Stock shall be entitled to receive stock, other securities or other
property or assets (including cash) with respect to or in exchange for such
Common Stock, or (iii) any sale or conveyance of all or substantially all of the
properties and assets of the Company to any other Person as a result of which
holders of Common Stock shall be entitled to receive stock, other securities or
other property or assets (including cash) with respect to or in exchange for
such Common Stock, then the Company 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) providing that such Note shall be convertible
into the kind and amount of shares of stock, other securities or other property
or assets (including cash) receivable upon such reclassification, change,
consolidation, merger, combination, sale or conveyance by a holder of a number
of shares of Common Stock issuable upon conversion of such

                                      106
<PAGE>

Notes (assuming, for such purposes, a sufficient number of authorized shares of
Common Stock are available to convert all such Notes) immediately prior to such
reclassification, change, consolidation, merger, combination, sale or conveyance
assuming such holder of Common Stock did not exercise his rights of election, if
any, as to the kind or amount of stock, other securities or other property or
assets (including cash) receivable upon such reclassification, change,
consolidation, merger, combination, sale or conveyance (provided that, if the
kind or amount of stock, other securities or other property or assets (including
cash) receivable upon such reclassification, change, consolidation, merger,
combination, 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 15.6 the kind and
amount of stock, other securities or other property or assets (including cash)
receivable upon such reclassification, change, consolidation, merger,
combination, 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). 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 Fifteen.

          The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each holder of Notes, at its address appearing on the
Note register provided for in Section 2.5 of 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.

          The above provisions of this Section shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

          If this Section 15.6 applies to any event or occurrence, Section 15.5
shall not apply.

          Section 15.7 TAXES ON SHARES ISSUED. The issue of stock certificates
on conversions of Notes shall be made without charge to the converting
Noteholder for any tax in respect of the issue thereof. The Company shall not,
however, be required to pay any tax which may be payable in

                                      107
<PAGE>

respect of any transfer involved in the issue and delivery of stock in any name
other than that of the holder of any Note 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.

          Section 15.8 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 Notes from time to time as such Notes are presented
for conversion.

          Before taking any action which would cause an adjustment reducing the
Conversion Price below the then par value, if any, of the shares of Common Stock
issuable upon conversion of the Notes, the Company will take all corporate
action which 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 Price.

          The Company covenants that all shares of Common Stock which may be
issued upon conversion of Notes 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 Notes 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 Securities and Exchange 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 Nasdaq National Market 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,

                                      108
<PAGE>

list and keep listed, so long as the Common Stock shall be so listed on such
exchange or automated quotation system, all Common Stock issuable upon
conversion of the Note; provided, however, 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 Notes into Common Stock in
accordance with the provisions of this Indenture, the Company covenants to list
such Common Stock issuable upon conversion of the Notes in accordance with the
requirements of such exchange or automated quotation system at such time.

          Section 15.9 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 Notes to determine the Conversion Price or whether any facts exist
which may require any adjustment of the Conversion Price, or with respect to the
nature or extent or calculation of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same. 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 securities or
property, which may at any time be issued or delivered upon the conversion of
any Note; 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 other securities or property or
cash upon the surrender of any Note for the purpose of conversion or to comply
with any of the duties, responsibilities or covenants of the Company contained
in this Article Fifteen. 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 15.6 relating either to the kind or
amount of shares of stock or securities or property (including cash) receivable
by Noteholders upon the conversion of their Notes after any event referred to in
such Section 15.6 or to any adjustment to be made with respect thereto, but,
subject to the provisions of Section 8.1, 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

                                      109
<PAGE>

obligated to file with the Trustee prior to the execution of any such
supplemental indenture) with respect thereto.

          Section 15.10 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 Price
pursuant to Section 15.5; or

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

          (c) of any reclassification or reorganization of the Common Stock of
the Company (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 or merger to which the Company
is a party and for which approval of any stockholders of the Company is
required, or of the sale or transfer of all or substantially all of the assets
of the Company or any Significant Subsidiary; or

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

the Company shall cause to be filed with the Trustee and to be mailed to each
holder of Notes at his address appearing on the Note register provided for in
Section 2.5 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, sale, transfer,
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, sale,
transfer, dissolution,

                                      110
<PAGE>

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, sale, transfer, dissolution,
liquidation or winding up.

including under Sections 2.4, 2.5, 2.6, 2.7, 3.3 and 3.5, 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

hereunder, if such successor corporation is otherwise eligible under this
Section 16.11, 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.

          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

                                      114
<PAGE>

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
Notes as the names and addresses of such holders appear on the Note 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 8.2, 8.3, 8.4, 9.3 and this Section 16.11
shall be applicable to any authenticating agent.

          Section 16.12 EXECUTION IN COUNTERPARTS. This Indenture may be

in the Notes shall be invalid, illegal or unenforceable, then (to the extent
permitted by law) the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

             4% CONVERTIBLE SUBORDINATED NOTES DUE FEBRUARY 1, 2007

          This Note is one of a duly authorized issue of Notes of the Company,
designated as its 4% Convertible Subordinated Notes Due February 1, 2007 (herein
called the "Notes"), limited to the aggregate principal amount of $500,000,000
(or $650,000,000 if the purchase right set forth in Section 2 of the Purchase
Agreement dated January 28, 2000 (as amended from time to time by the parties
thereto) by and between the Company and the Initial Purchaser is exercised in
full) all issued or to be issued under and pursuant to an Indenture dated as of
February 1, 2000 (herein called the "Indenture"), between the Company and Bank
One Trust Company, National Association, as trustee (herein called the
"Trustee"), to which Indenture and all indentures supplemental thereto reference
is hereby made for a description of the rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Company and
the holders of the Notes.

          In case an Event of Default (as defined in the Indenture) shall have
occurred and be continuing, the principal of, premium, if any, and accrued
interest (including Liquidated Damages (as defined in the Registration Rights
Agreement), if any) on all Notes may be declared by either the Trustee or the
holders of not less than 25% in aggregate principal amount of the Notes then
outstanding, and upon said declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

          The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Notes at the time outstanding, to execute
supplemental indentures adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of any supplemental
indenture or modifying in any manner the rights of the holders of the Notes;
provided, however, that no such supplemental indenture shall (i) extend the
fixed maturity of any Note, or reduce the rate or extend the time of payment of
interest thereon, or reduce the principal amount thereof or premium, if any,
thereon, or reduce any

                                      A-7
<PAGE>

amount payable upon redemption thereof, or impair the right of any Noteholder to
institute suit for the payment thereof, or make the principal thereof or
interest or premium, if any, thereon payable in any coin or currency other than
that provided in the Notes, or modify the provisions of the Indenture with
respect to the subordination of the Notes in a manner adverse to the Noteholders
in any material respect, or change the obligation of the Company to redeem any
Note upon the happening of a Fundamental Change (as defined in the Indenture) in
a manner adverse to the holders of the Notes, or impair the right to convert the
Notes into Common Stock subject to the terms set forth in the Indenture,
including Section 15.6 thereof, without the consent of the holder of each Note
so affected or (ii) reduce the aforesaid percentage of Notes, the holders of
which are required to consent to any such supplemental indenture, without the
consent of the holders of all Notes then outstanding. Subject to the provisions
of the Indenture, the holders of a majority in aggregate principal amount of the
Notes at the time outstanding may on behalf of the holders of all of the Notes
waive any past default or Event of Default under the Indenture and its
consequences except a default in the payment of interest (including Liquidated
Damages, if any) or any premium on, or the principal of, any of the Notes, or a
failure by the Company to convert any Notes into Common Stock of the Company, or
a default in the payment of the redemption price pursuant to Article Three of
the Indenture, or a default in respect of a covenant or provisions of the
Indenture which under Article Eleven of the Indenture cannot be modified without
the consent of the holders of each or all Notes then outstanding or affected
thereby. Any such consent or waiver by the holder of this Note (unless revoked
as provided in the Indenture) shall be conclusive and binding upon such holder
and upon all future holders and owners of this Note and any Notes which may be
issued in exchange or substitution hereof, irrespective of whether or not any
notation thereof is made upon this Note or such other Notes.

          The indebtedness evidenced by the Notes is, to the extent and in the
manner provided in the Indenture, expressly subordinated and subject in right of
payment to the prior payment in full of all Senior Indebtedness (as defined in
the Indenture) of the Company, whether outstanding at the date of the Indenture
or thereafter incurred, and this Note is issued subject to the provisions of the
Indenture with respect to such subordination. Each holder of this Note, by
accepting the same, agrees to and

                                      A-8
<PAGE>

shall be bound by such provisions 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 such
purpose.

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

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

          The Notes 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 Notes, Notes may be exchanged for a like
aggregate principal amount of Notes of any other authorized denominations.

          The Notes will not be redeemable at the option of the Company prior to
February 6, 2003. At any time on or after February 6, 2003, and prior to
maturity, the Notes may be redeemed at the option of the Company, in whole or in
part, upon mailing a notice of such redemption not less than 30 days before the
date fixed for redemption to the holders of Notes at their last registered
addresses, all as provided in the Indenture, at the following optional
redemption prices (expressed as percentages of the principal amount), together
in each case with accrued and unpaid interest (including Liquidated Damages, if
any) to, but excluding, the date fixed for redemption:

January 31, 2007

and 100% on February 1, 2007; provided, however, that if the date fixed for
redemption is on a February 1 or August 1, then the interest payable on such
date shall be paid to the holder of record on the preceding January 15 or July
15, respectively.

          The Company may not give notice of any redemption of the Notes if a
default in the payment of interest or premium, if any, on the Notes has occurred
and is continuing.

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

          If a Fundamental Change occurs at any time prior to maturity of the
Notes, the Notes will be redeemable on the 30th day after notice thereof (the
"Repurchase Date") at the option of the holder of the Notes at a redemption
price equal to 100% of the principal amount thereof, together with accrued
interest to (but excluding) the date of redemption; provided, however, that, if
such Repurchase Date is a February 1 or August 1, the interest payable on such
date shall be paid to the holder of record of the Notes on the preceding January
15 or July 15, respectively. The Notes will be redeemable in multiples of $1,000
principal amount. The Company shall mail to all holders of record of the Notes a
notice of the occurrence of a Fundamental Change and of the redemption right
arising as a result thereof on or before the 10th day after the occurrence of
such Fundamental Change. For a Note to be so redeemed 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

                                      A-10
<PAGE>

the terms of the Indenture, such Note with the form entitled "Option to Elect
Repayment Upon a Fundamental Change" on the reverse thereof duly completed,
together with such Note, duly endorsed for transfer, on or before the 30th day
after the date of such notice of a Fundamental Change (or if such 30th day is
not a Business Day, the immediately preceding Business Day).

          Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time after the original issuance of any Notes
through the close of business on the final maturity date of the Notes, or, as to
all or any portion hereof called for redemption, prior to the close of business
on the Business Day immediately preceding the date fixed for redemption (unless
the Company shall default in payment due upon redemption thereof), to convert
the principal hereof or any portion of such principal which is $1,000 or an
integral multiple thereof into that number of shares of the Company's Common
Stock (as such shares shall be constituted at the date of conversion) obtained
by dividing the principal amount of this Note or portion thereof to be converted
by the Conversion Price of $108.00, as may adjusted from time to time as
provided in the Indenture, upon surrender of this Note, together with a
conversion notice as provided in the Indenture (the form entitled "Conversion
Notice" on the reverse hereof), 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 the shares issuable on conversion are to be issued in the same name as
this Note, 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. No adjustment in respect of interest on any Note converted
or dividends on any shares issued upon conversion of such Note will be made upon
any conversion except as set forth in the next sentence. If this Note (or
portion hereof) is surrendered for conversion during the period from the close
of business on any record date for the payment of interest to the close of
business on the Business Day preceding the following interest payment date and
either (x) has not been called for redemption on a redemption date that occurs
during such period or (y) is not to be redeemed in connection with a Fundamental
Change on a Repurchase Date that occurs during such period, this Note (or
portion hereof being converted) must be accompanied by an amount, in New York
Clearing House funds or other funds acceptable to the Company, equal to the

                                      A-11
<PAGE>

interest payable on such interest payment date on the principal amount being
converted; provided, however, that no such payment shall be required if there
shall exist at the time of conversion a default in the payment of interest on
the Notes. No fractional shares will be issued upon any conversion, but an
adjustment and 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 Note or Notes for conversion. A Note in respect of which a
holder is exercising its right to require redemption upon a Fundamental Change
may be converted only if such holder withdraws its election to exercise such
right in accordance with the terms of the Indenture. Any Notes called for
redemption, unless surrendered for conversion by the holders thereof on or
before the close of business on the Business Day preceding the date fixed for
redemption, may be deemed to be redeemed from the holders of such Notes for an
amount equal to the applicable redemption price, together with accrued but
unpaid interest (including Liquidated Damages, if any) to (but excluding) the
date fixed for redemption, by one or more investment banks or other purchasers
who may agree with the Company (i) to purchase such Notes from the holders
thereof and convert them into shares of the Company's Common Stock and (ii) to
make payment for such Notes as aforesaid to the Trustee in trust for the
holders.

          Upon due presentment for registration of transfer of this Note at the
office or agency of the Company maintained for that purpose in accordance with
the terms of the Indenture, a new Note or Notes of authorized denominations for
an equal aggregate principal amount will be issued to the transferee in exchange
thereof; subject to the limitations provided in the 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 Note registrar may deem and treat the registered
holder hereof as the absolute owner of this Note (whether or not this Note shall
be overdue and notwithstanding any notation of ownership or other writing hereon
made by anyone other than the Company or any Note 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

                                      A-12
<PAGE>

any Note 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
Note.

          No recourse for the payment of the principal of or any premium or
interest on this Note, 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 Note, or
because of the creation of any indebtedness represented thereby, shall be had
against any incorporator, stockholder, employee, agent, officer or 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.

          This Note shall be deemed to be a contract made under the laws of New
York, and for all purposes shall be construed in accordance with the laws of New
York, without regard to principles of conflicts of laws.

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

Attention: Corporate Trust Administration

Ladies and Gentlemen:

          In connection with our proposed purchase of 4% Convertible
Subordinated Notes Due February 1, 2007 (the "Notes") of Conexant Systems, Inc.,
a Delaware corporation (the "Company"), we confirm that:

                  (i) we are an "accredited investor" within the meaning of Rule
         501(a)(1), (2) or (3) under the Securities Act of 1933, as amended (the
         "Securities Act"), or an entity in which all of the equity owners are
         accredited investors within the meaning of Rule 501(a)(1), (2) or (3)
         under the Securities Act (an "Institutional Accredited Investor");

                  (ii) (A) any purchase of Notes by us will be for our own
         account or for the account of one or more other Institutional
         Accredited Investors or as fiduciary for the account of one or more
         trusts, each of which is an "accredited investor" within the meaning of
         Rule 501(a)(7) under the Securities Act and for each of which we
         exercise sole investment discretion or (B) we are a "bank," within the
         meaning of Section 3(a)(2) of the Securities Act, or a "savings and
         loan association" or other institution described in Section 3(a)(5)(A)
         of the Securities Act that is acquiring Notes as fiduciary for the
         account of one or more institutions for which we exercise sole
         investment discretion;

                  (iii) in the event that we purchase any Notes, we will acquire
         Notes having a minimum purchase price of not less than $200,000 for our
         own account or for any separate account for which we are acting;

                  (iv) we have such knowledge and experience in financial and
         business matters that we are capable of

                                      B-1
<PAGE>

         evaluating the merits and risks of purchasing Notes; and

                  (v) we are not acquiring Notes with a view to distribution
         thereof or with any present intention of offering or selling Notes or
         the Common Stock of the Company issuable upon conversion thereof,
         except as permitted below; provided that the disposition of our
         property and property of any accounts for which we are acting as
         fiduciary shall remain at all times within our control.

                  We understand that the Notes are being offered in a
         transaction not involving any public offering within the United States
         within the meaning of the Securities Act and that the Notes and the
         Common Stock of the Company issuable upon conversion thereof have not
         been registered under the Securities Act, and we agree, on our own
         behalf and on behalf of each account for which we acquire any Notes,
         that if in the future we decide to resell or otherwise transfer such
         Notes or the Common Stock of the Company issuable upon conversion
         thereof, such Notes or Common Stock of the Company may be resold or
         otherwise transferred within the United States or to, or for the
         account or benefit of, U.S. persons only (i) to the Company or any
         subsidiary thereof, (ii) to a person who is a "qualified institutional
         buyer" (as defined in Rule 144A under the Securities Act) in a
         transaction meeting the requirements of Rule 144A, (iii) to an
         Institutional Accredited Investor that, prior to such transfer,
         furnishes to the Trustee for the Notes (or in the case of Common Stock
         of the Company, the transfer agent therefor) a signed letter containing
         certain representations and agreements relating to the restrictions on
         transfer of such securities (the form of which letter can be obtained
         from the Trustee or the transfer agent, as the case may be), (iv)
         pursuant to the exemption from registration provided by Rule 144 under
         the Securities Act (if applicable), or (v) pursuant to a registration
         statement that has been declared effective under the Securities Act
         (and which continues to be effective at the time of such transfer), and
         in each case, in accordance with any applicable securities law of any
         State of the U.S. and in accordance with the legends set forth on the
         Notes or the Common Stock of the Company issuable upon conversion
         thereof. We further agree to provide any

         person purchasing any of the Notes or the Common Stock of the Company
         issuable upon conversion thereof (other than pursuant to clause (iv) or
         (v) above) from us a notice advising such purchaser that resales of
         such securities are restricted as stated herein. We understand that the
         Trustee and transfer agent for the Notes and the Common Stock of the
         Company will not be required to accept for registration of transfer any
         Notes or any Common Stock of the Company issued upon conversion of the
         Notes, except upon presentation of evidence satisfactory to the Company
         that the foregoing restrictions on transfer have been complied with. We
         further understand that any Notes and any Common Stock of the Company
         issued upon conversion of the Notes will be in the form of definitive
         physical certificates and that such certificates will bear a legend
         reflecting the substance of this paragraph.

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

          THIS LETTER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,

CorVu Corporation
3400 W. 66th Street
Suite 445
Edina, Minnesota  55435

Ladies and Gentlemen:

         I hereby subscribe for the purchase of One Hundred Fifty Thousand
Units, each Unit consisting of one share of common stock of CorVu Corporation, a
Minnesota corporation (the "Company") and one warrant to purchase one share of
common stock of the Company at the price of One Cent ($.01) per share. The price
per Unit shall be Two Dollars ($2) for an aggregate purchase price of Three
Hundred Thousand Dollars ($300,000), upon the terms and conditions set forth
below. I acknowledge that this subscription is contingent upon acceptance in
whole or in part by the Company and herewith submit a check payable to "CorVu
Corporation" in full payment for such Units.

         I understand that the Shares have not been registered under the
Securities Act of 1933, as amended (the "Securities Act"), on the ground that
the acquisition of the Shares by me is exempt under Section 4(2) thereof.

         In partial consideration of the issuance of the Shares to me, I hereby
represent, warrant and agree as follows:

         1. Knowledge of Reliance. I understand and recognize that the Company,
in claiming a Section 4(2) exemption for the issuance of the Shares, is relying
upon the statements and representations made by me in this letter.

         2.       Investment Purpose in Acquiring the Shares.

                  a) Generally. I am acquiring the Shares for my account for
investment purposes only and not with a view to their resale or distribution. I
have no present intention to divide my participation with others or to resell or
otherwise dispose of all or any part of the Shares. In making these
representations, I understand that in the view of the Securities and Exchange
Commission the statutory exemption referred to above would not be available if,
notwithstanding my representations, I have in mind merely acquiring the Shares
for resale upon the occurrence or nonoccurrence of some predetermined event.

                  b) Compliance With Securities Act. I agree that if I sell or
distribute the Shares in the future, I shall do so pursuant to the requirements
of the Securities Act and applicable state securities laws. I agree that I will
not transfer any part of the Shares without (i) an effective registration under
the Securities Act and applicable state securities laws, or (ii) obtaining an
opinion of counsel satisfactory in form and substance to counsel for the Company
stating that the proposed transaction will not result in a prohibited
transaction under the Securities Act and applicable state securities laws.

                  c) Restrictive Legend. I agree that you may place a
restrictive legend on the Shares containing substantially the following
language:

                           "The Shares represented by this certificate have not
                           been registered under either the Securities Act of
                           1933, as amended, or applicable state securities
                           laws, and are subject to an investment letter. They
                           may not be sold, offered for sale or transferred in
                           the absence of an effective registration under the
                           Securities Act of 1933, as amended, and the
                           applicable state securities laws, or an opinion of
                           counsel satisfactory in form and substance to counsel
                           for the Company that such transaction will not result
                           in a prohibited transaction under the Securities Act
                           of 1933, as amended, or the applicable state
                           securities laws."

                  d) Stop Transfer Order. I agree that the Company may place a
stop transfer order with its registrar and stock transfer agent covering all
certificates representing the Shares.

         3. Knowledge of Restrictions Upon Transfer of the Shares. I understand
that the Shares are not freely transferable and may in fact be prohibited from
sale for an extended period of time and that, as a consequence thereof, I may
have extremely limited opportunities to dispose of the Shares. I understand that
Rule 144 of the Securities and Exchange Commission permits the transfer of
"restricted securities" of the type here involved only under certain conditions,
including a minimum one-year holding period and availability to the public of
certain information concerning the Company.

         4. Information About the Company. I acknowledge that I am a director of
the Company and that, by reason of my relationship with the Company as well as
other actions taken by me, I am fully aware of and advised concerning the
present financial condition of the Company, its business affairs and its
prospects for future business.

         5. Knowledgeable Investor. I understand that an investment in the
Company is speculative and involves a high degree of risk, and that there can be
no assurance that I will receive any return of or on my investment. I can bear
the economic risk of an investment in the Shares for an indefinite period of
time, can afford to sustain a complete loss of such investment, have no need for
liquidity in connection with an investment in the Shares, and can afford to hold
the Shares indefinitely.

                                          Yours very truly,

                                          Ismail Kurdi

term "Common Stock" means and includes the Company's presently authorized common
stock, no par value, and shall also include any capital stock of any class of
the Company hereafter authorized which shall not be limited to a fixed sum or
percentage in respect of the rights of the holders thereof to participate in
dividends or in the distribution of assets upon the voluntary or involuntary
liquidation, dissolution, or winding up of the Company.

         This Warrant is subject to the following provisions, terms and
conditions:

         1.       Exercise; Transferability.

         (a) The rights represented by this Warrant may be exercised by the
Holder hereof, in whole or in part (but not as to a fractional share of Common
Stock), by written notice of exercise (in the form attached hereto) delivered to
the Company at the principal office of the Company prior to the expiration of
this Warrant and accompanied or preceded by the surrender of this Warrant along
with a check in payment of the Warrant Exercise Price for such shares.

         (b) This Warrant is transferable in whole or in part, subject to
applicable federal and state securities laws and regulations. This Warrant may
not be sold, transferred, assigned, hypothecated or divided into two or more
Warrants of smaller denominations, nor may any Warrant shares issued pursuant to
exercise of this Warrant be transferred, except as provided in Section 7 hereof.

         2. Exchange and Replacement. Subject to Sections l and 7 hereof, this
Warrant is exchangeable upon the surrender hereof by the Holder to the Company
at its office for new Warrants of like tenor and date representing in the
aggregate the right to purchase the number of Warrant Shares purchasable
hereunder, each of such new Warrants to represent the right to purchase such
number of Warrant Shares (not to exceed the aggregate total number purchasable
hereunder) as shall be designated by the Holder at the time of such surrender.
Upon receipt by the Company of evidence reasonably satisfactory to it of the
loss, theft, destruction, or mutilation of this Warrant, and, in case of loss,
theft or destruction, of indemnity or security reasonably satisfactory to it,
and upon surrender and cancellation of this Warrant, if mutilated, the Company
will make and deliver a new Warrant of like tenor, in lieu of this Warrant;
provided, however, that if Kurdi shall be such Holder, an agreement of indemnity
by such Holder shall be sufficient for all purposes of this Section 2. This
Warrant shall be promptly canceled by the Company upon the surrender hereof in
connection with any exchange or replacement. The Company shall pay all expenses,
taxes (other than stock transfer taxes), and other charges payable in connection
with the preparation, execution, and delivery of Warrants pursuant to this
Section 2.

         3.       Issuance of the Warrant Shares.

         (a) The Company agrees that the shares of Common Stock purchased hereby
shall be and are deemed to be issued to the Holder as of the close of business
on the date on which this Warrant shall have been surrendered and the payment
made for such Warrant Shares as aforesaid. Subject to the provisions of the next
section, certificates for the Warrant Shares so purchased shall be delivered to
the Holder within a reasonable time, not exceeding fifteen (15) days after the
rights represented by this Warrant shall have been so exercised, and, unless
this Warrant has expired, a new Warrant representing the right to purchase the
number of Warrant Shares, if any, with respect to which this Warrant shall not
then have been exercised shall also be delivered to the Holder within such time.

         (b) Notwithstanding the foregoing, however, the Company shall not be
required to deliver any certificate for Warrant Shares upon exercise of this
Warrant except in accordance with exemptions from the applicable securities
registration requirements or registrations under applicable securities laws.
Nothing herein, however, shall obligate the Company to effect registrations
under federal or state securities laws, except as provided in Section 9. If
registrations are not in effect and if exemptions are not available when the
Holder seeks to exercise the Warrant, the Warrant exercise period will be
extended, if need be, to prevent the Warrant from expiring, until such time as
either registrations become effective or exemptions are available, and the
Warrant shall then remain exercisable for a period of at least 30 calendar days
from the date the Company delivers to the Holder written notice of the
availability of such registrations or exemptions. The Holder agrees to execute
such documents and make such representations, warranties, and agreements as may
be required solely to comply with the exemptions relied upon by the Company, or
the registrations made, for the issuance of the Warrant Shares.

         4. Covenants of the Company. The Company covenants and agrees that all
Warrant Shares will, upon issuance, be duly authorized and issued, fully paid,
nonassessable, and free from all taxes, liens, and charges with respect to the
issue thereof. The Company further covenants and agrees that during the period
within which the rights represented by this Warrant may be exercised, the
Company will at all times have authorized and reserved for the purpose of issue
or transfer upon exercise of the subscription rights evidenced by this Warrant a
sufficient number of shares of Common Stock to provide for the exercise of the
rights represented by this Warrant.

         5. Antidilution Adjustments. The provisions of this Warrant are subject
to adjustment as provided in this Section 5.

         (a) The Warrant Exercise Price shall be adjusted from time to time such
that in case the Company shall hereafter:

                  (i) pay any dividends on any class of stock of the Company
         payable in Common Stock or securities convertible into Common Stock;

                  (ii) subdivide its then outstanding shares of Common Stock
         into a greater number of shares; or

                  (iii) combine outstanding shares of Common Stock, by
         reclassification or otherwise;

then, in any such event, the Warrant Exercise Price in effect immediately prior
to such event shall (until adjusted again pursuant hereto) be adjusted
immediately after such event to a price (calculated to the nearest full cent)
determined by dividing (a) the number of shares of Common Stock outstanding
immediately prior to such event, multiplied by the then existing Warrant
Exercise Price, by (b) the total number of shares of Common Stock outstanding
immediately after such event (including the maximum number of shares of Common
Stock issuable in respect of any securities convertible into Common Stock), and
the resulting quotient shall be the adjusted Warrant Exercise Price per share.
An adjustment made pursuant to this Subsection shall become effective
immediately after the record date in the case of a dividend or distribution and
shall become effective immediately after the effective date in the case of a
subdivision, combination or reclassification. If, as a result of an adjustment
made pursuant to this Subsection, the Holder of any Warrant thereafter
surrendered for exercise shall become entitled to receive shares of two or more
classes of capital stock or shares of Common Stock and other capital stock of
the Company, the Board of Directors (whose determination shall be conclusive)
shall determine the allocation of the adjusted Warrant Exercise Price between or
among shares of such classes of capital stock or shares of Common Stock and
other capital stock. All calculations under this Subsection shall be made to the
nearest cent or to the nearest 1/100 of a share, as the case may be. In the
event that at any time as a result of an adjustment made pursuant to this
Subsection, the holder of any Warrant thereafter surrendered for exercise shall
become entitled to receive any shares of the Company other than shares of Common
Stock, thereafter the Warrant Exercise Price of such other shares so receivable
upon exercise of any Warrant shall be subject to adjustment from time to time in
a manner and on terms as nearly equivalent as practicable to the provisions with
respect to Common Stock contained in this Section.

         (b) Upon each adjustment of the Warrant Exercise Price pursuant to
Section 5(a) above, the Holder of each Warrant shall thereafter (until another
such adjustment) be entitled to purchase at the adjusted Warrant Exercise Price
the number of shares, calculated to the nearest full share, obtained by
multiplying the number of shares specified in such Warrant (as adjusted as a
result of all adjustments in the Warrant Exercise Price in effect prior to such
adjustment) by the Warrant Exercise Price in effect prior to such adjustment and
dividing the product so obtained by the adjusted Warrant Exercise Price.

         (c) In case of any consolidation or merger to which the Company is a
party other than a merger or consolidation in which the Company is the
continuing corporation, or in case of any sale or conveyance to another
corporation of the property of the Company as an entirety or substantially as an
entirety, or in the case of any statutory exchange of securities with another
corporation (including any exchange effected in connection with a merger of a
third corporation into the Company), there shall be no adjustment under
Subsection (a) of this Section above but the Holder of each Warrant then
outstanding shall have the right thereafter to convert such Warrant into the
kind and amount of shares of stock and other securities and property which he
would have owned or have been entitled to receive immediately after such
consolidation, merger, statutory exchange, sale, or conveyance had such Warrant
been converted immediately prior to the effective date of such consolidation,
merger, statutory exchange, sale, or conveyance and in any such case, if
necessary, appropriate adjustment shall be made in the application of the
provisions set forth in this Section with respect to the rights and interests
thereafter of any Holders of the Warrant, to the end that the provisions set
forth in this Section shall thereafter correspondingly be made applicable, as
nearly as may reasonably be, in relation to any shares of stock and other
securities and property thereafter deliverable on the exercise of the Warrant.
The provisions of this Subsection shall similarly apply to successive
consolidations, mergers, statutory exchanges, sales or conveyances.

         (d) Upon any adjustment of the Warrant Exercise Price, then and in each
such case, the Company shall give written notice thereof, by first-class mail,
postage prepaid, addressed to the Holder as shown on the books of the Company,
which notice shall state the Warrant Exercise Price resulting from such
adjustment and the increase or decrease, if any, in the number of shares of
Common Stock purchasable at such price upon the exercise of this Warrant,
setting forth in reasonable detail the method of calculation and the facts upon
which such calculation is based.

         6. No Voting Rights. This Warrant shall not entitle the Holder to any
voting rights or other rights as a shareholder of the Company.

         7. Notice of Transfer of Warrant or Resale of the Warrant Shares.

         (a) Subject to the sale, assignment, hypothecation, or other transfer
restrictions set forth in Section 1 hereof, the Holder, by acceptance hereof,
agrees to give written notice to the Company before transferring this Warrant or
transferring any Warrant Shares of such Holder's intention to do so, describing
briefly the manner of any proposed transfer. Promptly upon receiving such
written notice, the Company shall present copies thereof to the Company's
counsel and to counsel to the original purchaser of this Warrant. If in the
opinion of each such counsel the proposed transfer may be effected without
registration or qualification (under any federal or state securities laws), the
Company, as promptly as practicable, shall notify the Holder of such opinion,
whereupon the Holder shall be entitled to transfer this Warrant or to dispose of
Warrant Shares received upon the previous exercise of this Warrant, all in
accordance with the terms of the notice delivered by the Holder to the Company;
provided that an appropriate legend may be endorsed on this Warrant or the
certificates for such Warrant Shares respecting restrictions upon transfer
thereof necessary or advisable in the opinion of counsel and satisfactory to the
Company to prevent further transfers which would be in violation of Section 5 of
the Securities Act of 1933, as amended (the "1933 Act") and applicable state
securities laws; and provided further that the prospective transferee or
purchaser shall execute such documents and make such representations,
warranties, and agreements as may be required solely to comply with the
exemptions relied upon by the Company for the transfer or disposition of the
Warrant or Warrant Shares.

         (b) If in the opinion of either of the counsel referred to in this
Section 7, the proposed transfer or disposition of this Warrant or such Warrant
Shares described in the written notice given pursuant to this Section 7 may not
be effected without registration or qualification of this Warrant or such
Warrant Shares the Company shall promptly give written notice thereof to the
Holder, and the Holder will limit his activities in respect to such as, in the
opinion of both such counsel, are permitted by law.

         8. Fractional Shares. Fractional shares shall not be issued upon the
exercise of this Warrant, but in any case where the holder would, except for the
provisions of this Section, be entitled under the terms hereof to receive a
fractional share, the Company shall, upon the exercise of this Warrant for the
largest number of whole shares then called for, pay a sum in cash equal to the
sum of (a) the excess, if any, of the Market Price of such fractional share over
the proportional part of the Warrant Exercise Price represented by such
fractional share, plus (b) the proportional part of the Warrant Exercise Price
represented by such fractional share. For purposes of this Section, the term
"Market Price" with respect to shares of Common Stock of any class or series
means:

                  (i) if the Company's Common Stock is traded on an exchange or
         is quoted on the Nasdaq National Market, then the average closing or
         last sale prices, respectively, reported for the ten (10) business days
         immediately preceding exercise of the Warrant,

                  (ii) if the Company's Common Stock is not traded on an
         exchange or on the Nasdaq National Market but is traded on the Nasdaq
         SmallCap Market or other over-the-counter market, then the average
         closing bid and asked prices reported for the ten (10) business days
         immediately preceding the exercise of the Warrant, and

                  (iii) if the Company's Common Stock is not traded on an
         exchange, the Nasdaq National Market, or the Nasdaq SmallCap Market or
         other over-the-counter market, then the price established by the
         Company's Board of Directors.

         IN WITNESS WHEREOF, CorVu Corporation has caused this Warrant to be
signed by its duly authorized officer and this Warrant to be dated April 27,
1999.
