aggregate principal amount of $175,000,000 (except pursuant to Sections 2.05,

part of this Indenture and, to the extent applicable, the Company and the

such terms and provisions and to be bound thereby.

          Any of the Notes may have such letters, numbers or other marks of
identification and such notations, legends, endorsements or changes as the

<Page>

may be listed, or to conform to usage, or to indicate any special limitations or

Section 2.05(b), all of the Notes will be represented by one or more Notes in

amount of outstanding Notes from time to time endorsed thereon and that the
aggregate amount of outstanding Notes represented thereby may from time to time
be increased or reduced to reflect redemptions, repurchases, conversions,
transfers or exchanges permitted hereby. Any endorsement of a Global Note to
reflect the amount of any increase or decrease in the amount of outstanding
Notes represented thereby shall be made by the Trustee or the Custodian, at the
direction of the Trustee, in such manner and upon instructions given by the
holder of such Notes in accordance with this Indenture. Payment of principal of

Subject to Section 2.02, the Notes shall be issuable in registered form without
coupons in denominations of $1,000 principal amount and multiples thereof. Each
Note shall be dated the date of its authentication and shall bear interest from
the date specified on the face of the form of Note attached as Exhibit A hereto.
Interest on the Notes shall be computed on the basis of a 360-day year comprised
of twelve 30-day months.

          The Person in whose name any Note (or its Predecessor Note) is
registered on the Note register at the close of business on any record date with
respect to any interest payment date shall be entitled to receive the interest
payable on such interest payment date, except that the interest payable upon
redemption or repurchase will be payable to the Person to whom principal is
payable pursuant to such redemption or repurchase (unless the redemption date or
the Repurchase Date, as the case may be, is an interest payment date, in which
case 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 applicable record
date). Interest shall be payable at the office of the Company maintained by the
Company for such purposes in the Borough of Manhattan, The City of New York,
which shall initially be the Corporate Trust Office of the Trustee and may, as
the Company shall specify to the paying agent in writing by each record date, be
paid either (i) by check mailed to the address of the Person entitled thereto as
it appears in the Note register (PROVIDED that any holder of Notes with an
aggregate principal amount in excess of $2,000,000 shall, at the written
election of such holder (such election to be made prior to the relevant record
date and to contain appropriate wire transfer information), be paid by wire
transfer in immediately available funds) or (ii) by transfer to an account
maintained by such Person located

                                        9

wire transfer of immediately available funds to the account of the Depositary or
its nominee. The term "RECORD DATE" with respect to any interest payment date
shall mean the January 1 or July 1 preceding the applicable January 15 or July
15 interest payment date, respectively.

          Any interest on any Note which is payable, but is not punctually paid
or duly provided for, on any January 1 or July 1 (herein called "DEFAULTED
INTEREST") shall forthwith cease to be payable to the Noteholder on the relevant
record date by virtue of his having been such Noteholder, and such Defaulted
Interest shall be paid by the Company, at its election in each case, as provided
in clause (1) or (2) below:

The Company may elect to make payment of any Defaulted Interest to the Persons
in whose names the Notes (or their respective Predecessor Notes) are registered
at the close of business on a special record date for the payment of such
Defaulted Interest, which shall be fixed in the following manner. The Company
shall notify the Trustee in writing of the amount of Defaulted Interest proposed
to be paid on each Note and the date of the proposed payment (which shall be not
less than twenty-five (25) days after the receipt by the Trustee of such notice,
unless the Trustee shall consent to an earlier date), and at the same time the
Company shall deposit with the Trustee an amount of money equal to the aggregate
amount to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit on or prior to the
date of the proposed payment, such money when deposited to be held in trust for
the benefit of the Persons entitled to such Defaulted Interest as in this clause
provided. Thereupon the Trustee shall fix a special record date for the payment
of such Defaulted Interest which shall be not more than fifteen (15) days and
not less than ten (10) days prior to the date of the proposed payment, and not
less than ten (10) days after the receipt by the Trustee of the notice of the
proposed payment. The Trustee shall promptly notify the Company of such special
record date and, in the name and at the expense of the Company, shall cause
notice of the proposed payment of such Defaulted Interest and the special record
date therefor to be mailed, first-class postage prepaid, to each holder at his
address as it appears in the Note register, not less than ten (10) days prior to
such special record date. Notice of the proposed payment of such Defaulted
Interest and the special record date therefor having been so mailed, such
Defaulted Interest shall be paid to the Persons in whose names the Notes (or
their respective Predecessor Notes) are registered at the close of business on
such special record date and shall no longer be payable pursuant to the
following clause (2) of this Section 2.03.

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 2.04.   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 of Directors, Chief Executive Officer, President or any
Vice President and attested by its Secretary or any of its Assistant
Secretaries. The signature of any of these officers or the Company's seal on the
Notes may be manual or facsimile. Only such Notes as shall bear thereon a
certificate of

                                       10
<Page>

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 15.11), 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 2.05.   EXCHANGE AND REGISTRATION OF TRANSFER OF NOTES;
RESTRICTIONS ON TRANSFER. (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 4.02
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 4.02.

          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 2.05, 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 4.02. 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.

                                       11
<Page>

          All Notes presented or surrendered for registration of transfer or for
exchange, redemption, repurchase or conversion shall (if so required by the
Company or the Note registrar) be duly endorsed, or be accompanied by a written
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 to any holder for any registration of
transfer or exchange of Notes, but either the Company, the Trustee or both may
require payment by the holder of a sum sufficient to cover any tax, assessment
or other governmental charge that may be imposed in connection with any
registration of transfer or exchange of 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 3.02, (c)
any Notes or portions thereof surrendered for conversion pursuant to Article 14,
(d) any Notes or portions thereof tendered for redemption (and not withdrawn)
pursuant to Section 3.05 or (e) any Notes or portions thereof tendered for
repurchase (and not withdrawn) pursuant to Section 3.06.

                  (i)     Each Global Note authenticated under this Indenture
          shall be registered in the name of the Depositary or a nominee thereof
          and delivered to such Depositary or a nominee thereof or Custodian
          therefor, and each such Global Note shall constitute a single Note for
          all purposes of this Indenture.

                  (ii)    Notwithstanding any other provision in this Indenture,
          no Global Note may be exchanged in whole or in part for Notes
          registered, and no transfer of a Global Note in whole or in part may
          be registered, in the name of any Person other than the Depositary or
          a nominee thereof unless (A) the Depositary (i) has notified the
          Company that it is unwilling or unable to continue as Depositary for
          such Global Note or (ii) has ceased to be a clearing agency registered
          under the Exchange Act and a successor Depositary is not appointed by
          the Company within 90 days, (B) an Event of Default has occurred and
          is continuing and the maturity of the Notes shall have been
          accelerated in accordance with the terms of the Notes and any holder
          shall have requested in writing the issuance of definitive
          certificated securities, or (C) the Company, in its sole discretion,
          notifies the Trustee in writing that it no longer wishes to have all
          the Notes represented by Global Notes. Any Global Note exchanged
          pursuant to clause (A) or (B) above shall be so exchanged in whole and
          not in part and any Global Note exchanged pursuant to clause (C) above
          may be exchanged in whole or from time to time in part as directed by
          the Company. Any Note issued in exchange for a Global Note or any
          portion thereof shall be a Global Note; PROVIDED that any such Note so
          issued that is registered in the name of a Person other than the
          Depositary or a nominee thereof shall not be a Global Note.

          portion thereof pursuant to clause (ii) above and which is not a
          Global Note shall be issued in definitive, fully registered form,
          without interest coupons, shall have an aggregate principal amount
          equal to that of such Global Note or portion thereof to be so
          exchanged, shall be registered in such names and be in such authorized
          denominations as the Depositary shall designate and shall bear any
          legends required hereunder. Any Global Note to be exchanged in whole
          shall be surrendered by the Depositary to the Trustee, as Note
          registrar. With regard to any Global Note to be exchanged in part,
          either such Global Note shall be so surrendered for exchange or, if
          the Trustee is acting as Custodian for the Depositary or its nominee
          with respect to such Global Note, the principal amount thereof shall
          be reduced, by an amount equal to the portion thereof to be so
          exchanged, by means of an appropriate adjustment made on the records
          of the Trustee. Upon any such surrender or adjustment, the Trustee
          shall authenticate and make available for delivery the Note issuable
          on such exchange to or upon the written order of the Depositary or an
          authorized representative thereof.

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

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

                  (vi)    At such time as all interests in a Global Note have
          been redeemed, repurchased, converted, canceled or exchanged for Notes
          in certificated form, such Global Note 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 Global Note is
          redeemed, repurchased, converted, canceled or exchanged for Notes in
          certificated form, the principal amount of such Global Note shall, in
          accordance with the standing procedures and instructions existing
          between the Depositary and the Custodian, be appropriately reduced,
          and an endorsement shall be made on such Global Note, by the Trustee
          or the Custodian, at the direction of the Trustee, to reflect such
          reduction.

                                       13

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

          Until the expiration of the holding period applicable to sales thereof
under Rule 144(k) under the Securities Act (or any successor provision), any
certificate evidencing such 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 2.05(d), 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
          EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION
          HEREOF, THE HOLDER (1) REPRESENTS THAT IT IS A "QUALIFIED
          INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES
          ACT); (2) AGREES THAT IT WILL NOT, PRIOR TO EXPIRATION OF THE HOLDING
          PERIOD APPLICABLE TO SALES OF THIS NOTE UNDER RULE 144(k) UNDER THE
          SECURITIES ACT (OR ANY SUCCESSOR PROVISION), RESELL OR OTHERWISE
          TRANSFER THIS NOTE OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF
          THIS NOTE EXCEPT (A) TO JETBLUE AIRWAYS CORPORATION OR ANY SUBSIDIARY
          THEREOF, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH
          RULE 144A UNDER THE SECURITIES ACT, (C) PURSUANT TO THE EXEMPTION FROM
          REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF
          AVAILABLE) OR (D) 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)(D) ABOVE), IT WILL
          FURNISH TO WILMINGTON TRUST COMPANY, AS TRUSTEE (OR A SUCCESSOR
          TRUSTEE, AS APPLICABLE) AND UPON THE COMPANY'S REQUEST, TO THE
          COMPANY, SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS
          THE TRUSTEE AND THE COMPANY MAY REASONABLY REQUIRE TO CONFIRM THAT
          SUCH TRANSFER IS

                                       14
<Page>

          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 THIS NOTE IS
          TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. THIS
          LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THIS NOTE
          PURSUANT TO CLAUSE (2)(D) ABOVE OR UPON ANY TRANSFER OF THIS NOTE
          UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR
          PROVISION). THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE
          TO REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE
          FOREGOING RESTRICTION.

          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 2.05, 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 2.05(c). If
the Restricted Security surrendered for exchange is represented by a Global Note
bearing the legend set forth in this Section 2.05(c), the principal amount of
the legended Global Note shall be reduced by the appropriate principal amount
and the principal amount of a Global Note without the legend set forth in this
Section 2.05(c) shall be increased by an equal principal amount. If a Global
Note without the legend set forth in this Section 2.05(c) is not then
outstanding, the Company shall execute and the Trustee shall authenticate and
deliver an unlegended Global Note to the Depositary.

          (d)     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 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)

                                       15
<Page>

          TO JETBLUE AIRWAYS CORPORATION 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) PURSUANT TO THE
          EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES
          ACT (IF AVAILABLE) OR (D) 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)(D) ABOVE),
          IT WILL FURNISH TO EQUISERVE TRUST COMPANY, N.A., 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)(D) ABOVE) A
          NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. THIS LEGEND WILL BE
          REMOVED UPON THE EARLIER OF THE TRANSFER OF THE COMMON STOCK EVIDENCED
          HEREBY PURSUANT TO CLAUSE (1)(D) 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).

          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 2.05(d).

          (e)     Any Note or Common Stock issued upon the conversion 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 under the Securities Act).

          SECTION 2.06.   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

                                       16
<Page>

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.

          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, either the Company, the Trustee
or both may require the payment by the holder of a sum sufficient to cover any
tax, assessment or other governmental charge that may be imposed in relation
thereto and any other expenses connected therewith. In case any Note which has
matured or is about to mature or has been called for redemption or has been
tendered for redemption upon a Designated Event (and not withdrawn) or has been
surrendered for repurchase on a Repurchase Date (and not withdrawn) or is to be
converted 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 in connection with such substitution,
and, in every case of destruction, loss or theft, the applicant shall also
furnish to the Company, the Trustee and, if applicable, any paying agent or
conversion agent evidence to their satisfaction of the destruction, loss or
theft of such Note and of the ownership thereof.

          Every substitute Note issued pursuant to the provisions of this
Section 2.06 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 or redemption
or repurchase 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 or redemption or repurchase of negotiable instruments or other
securities without their surrender.

          SECTION 2.07.   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

                                       17
<Page>

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
and thereupon any or all temporary Notes may be surrendered in exchange
therefor, at each office or agency maintained by the Company pursuant to Section
4.02 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 2.08.   CANCELLATION OF NOTES. If the Company shall acquire
any of the Notes, such acquisition shall not operate as a redemption, repurchase
or satisfaction of the indebtedness represented by such Notes unless and until
the same are delivered to the Trustee for cancellation. All Notes surrendered
for the purpose of payment, redemption, repurchase, conversion, exchange or
registration of transfer shall, if surrendered to the Company or any paying
agent or any 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.

          SECTION 2.09.   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 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 III
                       REDEMPTION AND REPURCHASE OF NOTES

          SECTION 3.01.   REDEMPTION OF NOTES AT THE OPTION OF THE COMPANY.
Except as otherwise provided in Section 3.05, the Company may not redeem any
Notes prior to July 18, 2006. At any time on or after July 18, 2006, the Company
may redeem any of the Notes at a redemption price of 100% of the principal
amount of the Notes being redeemed, plus accrued and unpaid interest, if the
Closing Sale Price on the Nasdaq National Market excees 150% of the Conversion
Price for at least 20 Trading Days in any period of 30 consecutive Trading Days
ending as of the date the Company gives notice of such redemption or within two
Business Days prior to giving such notice. At any time on or after July 18, 2006
and prior to maturity, the Notes

                                       18
<Page>

may be redeemed at the option of the Company (an "OPTIONAL REDEMPTION"), in
whole or in part, upon notice as set forth in Section 3.02, at 100% of the
principal amount of the Notes to be redeemed, together with accrued and unpaid
interest, if any, to, but excluding the date fixed for redemption.

          SECTION 3.02.    NOTICE OF OPTIONAL REDEMPTION; 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 3.01, 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 redemption date to each holder of Notes so to be redeemed as a
whole or in part at its last address as the same appears on the Note register;
PROVIDED that if the Company shall give such notice, it shall also give written
notice of the redemption date to the Trustee. Such mailing shall be by first
class mail. The notice, if mailed in the manner herein provided, shall be
conclusively presumed to have been duly given, whether or not the holder
receives such notice. In any case, failure to give such notice by mail or any
defect in the notice to the holder of any 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 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 Rate 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
redemption date, 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 3.02, the Company will deposit with
the Trustee or with one or more paying agents (or, if the Company is acting as
the paying agent, set aside, segregate and hold in trust as provided in Section
4.04) 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 redemption date; PROVIDED that if such payment is made on the
redemption date it must be received by the Trustee or paying

                                       19
<Page>

agent, as the case may be, by 10:00 a.m. New York City time on such date. The
Company shall be entitled to retain any interest, yield or gain on amounts
deposited with the Trustee or any paying agent pursuant to this Section 3.02 in
excess of amounts required hereunder to pay the redemption price and accrued
interest to, but excluding, the redemption date. If any Note called for
redemption is converted pursuant hereto prior to such redemption date, any money
deposited with the Trustee or any paying agent or so segregated and held in
trust for the redemption of such 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 pursuant to Section 3.01, 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.

          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
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 possible) 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 3.03.   PAYMENT OF NOTES CALLED FOR REDEMPTION BY THE COMPANY.
If notice of redemption has been given as provided in Section 3.02, 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 redemption date, 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 immediately preceding the redemption date, such
Notes shall cease to be convertible into Common Stock and, except as provided in
Sections 7.06 and 12.04, 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 interest to
(but excluding) the redemption date. 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

redemption date; PROVIDED that if the applicable redemption date is an interest
payment date, the interest payable on such interest payment date shall be
payable to the holders of record of such Notes on the applicable 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 on the Notes. If any Note called for redemption shall not be so paid
upon surrender thereof for redemption, the principal shall, until paid or duly
provided for, bear interest from the redemption date at a rate equal to 1% per
annum plus the rate borne by the Note (without duplication of the 1% increase
provided for under Section 6.02) and such Note shall remain convertible into
Common Stock until the principal and interest shall have been paid or duly
provided for.

          SECTION 3.04.   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
banks 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 3, 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
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 14) 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 3.05.   REDEMPTION AT OPTION OF HOLDERS UPON A DESIGNATED
EVENT. (a) If there shall occur a Designated Event 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 a multiple of $1,000 principal amount, on the date
(the "DESIGNATED EVENT REDEMPTION DATE") that is thirty (30) days after the date
of the Designated Event Notice (as defined in Section 3.05(b)) of such
Designated Event (or, if such

                                       21
<Page>

30th day is not a Business Day, the next succeeding Business Day) at a
redemption price equal to 100% of the principal amount thereof, together with
accrued interest to, but excluding, the Designated Event Redemption Date;
PROVIDED that if such Designated Event Redemption Date is an interest payment
date, then the interest payable on such interest payment date shall be paid to
the holders of record of the Notes on the applicable record date instead of the
holders surrendering the Notes for redemption on such date.

          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 make available for delivery to the holder thereof, at the
expense of the Company, a new Note or Notes, of authorized denominations, in
aggregate principal amount equal to the unredeemed portion of the Notes
presented.

          (b)     On or before the tenth day after the occurrence of a
Designated Event, the Company or at its written request (which must be received
by the Trustee at least five (5) Business Days prior to the date the Trustee is
requested to give notice as described below, unless the Trustee shall agree in
writing to a shorter period), the Trustee, in the name of and at the expense of
the Company, shall mail or cause to be mailed to all holders of record on the
date of the Designated Event a notice (the "DESIGNATED EVENT NOTICE") of the
occurrence of such Designated Event and of the 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 3.02
(without regard for the time limits set forth therein). If the Company shall
give such notice, the Company shall also deliver a copy of the Designated Event
Notice to the Trustee at such time as it is mailed to Noteholders. Concurrently
with the mailing of any Designated Event Notice, the Company shall issue a press
release announcing such Designated Event referred to in the Designated Event
Notice, the form and content of which press release shall be determined by the
Company in its sole discretion. The failure to issue any such press release or
any defect therein shall not affect the validity of the Designated Event Notice
or any proceedings for the redemption of any Note which any Noteholder may elect
to have the Company redeem as provided in this Section 3.05.

          Each Designated Event Notice shall specify the circumstances
constituting the Designated Event, the Designated Event Redemption 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
Designated Event Redemption Date (the "DESIGNATED EVENT EXPIRATION TIME"), that
the holder shall have the right to withdraw any Notes surrendered prior to the
Designated Event 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, the amount of interest accrued on each Note to (but excluding)
the Designated Event Redemption Date and the CUSIP number or numbers of the
Notes (if then generally in use).

          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 redemption of the Notes pursuant to this Section 3.05.

                                       22

          (c)     For a Note, other than a Global 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 pursuant to Section 4.02, such Note with the
form entitled "Option to Elect Repayment Upon A Designated Event" on the reverse
thereof duly completed, together with such Notes duly endorsed for transfer, on
or before the Designated Event Expiration Time. All questions as to the
validity, eligibility (including time of receipt) and acceptance of any Note for
redemption shall be determined by the Company, whose determination shall be
final and binding absent manifest error.

          (d)     On or prior the Designated Event Redemption Date, the Company
will deposit with the Trustee or with one or more paying agents (or, if the
Company is acting as the paying agent, set aside, segregate and hold in trust as
provided in Section 4.04) an amount of money sufficient to redeem on the
Designated Event Redemption Date all the Notes to be redeemed on such date at
the appropriate redemption price, together with accrued interest to, but
excluding, the Designated Event Redemption Date; PROVIDED that if such payment
is made on the Designated Event 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. Payment for Notes surrendered for redemption (and not withdrawn)
prior to the Designated Event Expiration Time will be made promptly (but in no
event more than five (5) Business Days) following the Designated Event
Redemption Date by mailing checks for the amount payable to the holders of such
Notes entitled thereto as they shall appear in the Note register.

          (e)     In the case of a reclassification, change, consolidation,
merger, combination, binding share exchange, sale or conveyance to which Section
14.06 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 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 Designated Event, including without limitation the applicable
provisions of this Section 3.05 and the definitions of Common Stock and
Designated Event, 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 Designated Event.

option of the holder thereof, upon:

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

          (b)     delivery or book-entry transfer of the Notes to the Trustee

     of the applicable Repurchase Notice (together with all necessary
     endorsements) at the office of the Trustee (or other paying agent appointed
     by the Company), such delivery being a condition to receipt by the holder
     of the purchase price therefor; PROVIDED that such purchase price shall be
     so paid pursuant to this Section 3.06 only if the Note so delivered to the
     Trustee (or other paying agent appointed by the Company) shall conform in
     all respects to the description thereof in the related Repurchase Notice.

          The Company shall purchase from the holder thereof, pursuant to this

this Section 3.06 shall be consummated by the delivery of the consideration to

          other paying agent appointed by the Company) to collect the purchase
          price;

                  (6) state the CUSIP number of the Notes.

Company Repurchase Notices may be given by the Company or, at the Company's
request, the Trustee shall give such Company Repurchase Notice in the Company's

available funds if deposited on such Business Day) sufficient to pay the
aggregate purchase price of all the Notes or portions thereof that are to be

price of all the Notes, or portions thereof that are to purchased as of the
Repurchase Date, on or after the Repurchase Date (i) the Notes will cease to be

other rights of the holders of such Notes will terminate, whether or not

purchase price upon delivery of the Notes.

          SECTION 3.10.   NOTES REPURCHASED IN PART. Upon presentation of any
Note repurchased only in part, the Company shall execute and the Trustee shall

agent appointed by the Company) shall return to the Company any cash that remain
unclaimed, together with interest, if any, thereon, held by them for the payment

cash deposited by the Company pursuant to Section 3.09 exceeds the aggregate
purchase price of the Notes or portions thereof which the Company is obligated
to purchase as of the Repurchase Date then, unless otherwise agreed in writing
with the Company, promptly after the Business Day following the Repurchase Date,
the Trustee shall return any such excess to the Company together with interest,

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
shall be considered as one such office or agency of the Company for each of the
aforesaid purposes.

that there shall at all times be a Trustee hereunder.

          SECTION 4.04.   PROVISIONS AS TO PAYING AGENT. (a) If the Company

<Page>

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 4.04:

                  (1)     that it will hold all sums held by it as such agent
          for the payment of the principal of, 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 of, or interest on, the Notes when the same shall be
          due and payable; and

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

          The Company shall, on or before each due date of the principal of, 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 or interest, and (unless such paying agent is the Trustee) the Company
will promptly notify the Trustee of any failure to take such action; PROVIDED
that if such deposit is made on the due date, such deposit shall be received by
the paying agent by 10:00 a.m. New York City time, on such date.

          (b)     If the Company shall act as the paying agent, it will, on or
before each due date of the principal of, or interest 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 or interest 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, or interest on, the Notes when the same shall become due and
payable.

          (c)     Anything in this Section 4.04 to the contrary notwithstanding,
the Company may, at any time, for the purpose of obtaining a satisfaction and
discharge of this Indenture, or for any other reason, pay or cause to be paid to
the Trustee all sums held in trust by the Company or any paying agent hereunder
as required by this Section 4.04, such sums to be held by the Trustee upon the
trusts herein contained and upon such payment by the Company or any paying agent
to the Trustee, the Company or such paying agent shall be released from all
further liability with respect to such sums.

          (d)     Anything in this Section 4.04 to the contrary notwithstanding,
the agreement to hold sums in trust as provided in this Section 4.04 is subject
to Sections 12.03 and 12.04.

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

          SECTION 4.05.   RULE 144A INFORMATION REQUIREMENT. Within the period
prior to the expiration of the holding period applicable to sales thereof under
Rule 144(k) under the

                                       28
<Page>

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 4.06.   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, an Officers' Certificate stating whether or not to the best
knowledge of the signers thereof the Company is in default in the performance
and observance of any of the terms, provisions and conditions of this Indenture
(without regard to any period of grace or requirement of notice provided
hereunder) and, if the Company shall be in default, specifying all such defaults
and the nature and the status thereof of which the signer may have knowledge.

          The Company will deliver to the Trustee, as soon as possible and in
any event within 30 days after the Company becomes aware of any Event of Default
or an event which, with notice or the lapse of time or both, would constitute an

default or Event of Default and the action that the Company has taken, is taking
or proposes to take with respect thereto.

          Any notice required to be given under this Section 4.06 shall be
delivered to a Responsible Officer of the Trustee at its Corporate Trust Office.

          SECTION 4.07.   LIQUIDATED DAMAGES NOTICE. In the event that the
Company is required to pay Liquidated Damages to holders of Notes pursuant to
the Registration Rights Agreement, the Company will provide written notice
("LIQUIDATED DAMAGES NOTICE") to the Trustee of its obligation to pay Liquidated
Damages no later than fifteen (15) days prior to the proposed payment date for
the Liquidated Damages, and the Liquidated Damages Notice shall set forth the
amount of Liquidated Damages to be paid by the Company on such payment date. The
Trustee shall not at any time be under any duty or responsibility to any holder

extent or calculation of the amount of Liquidated Damages when made, or with
respect to the method employed in such calculation of the Liquidated Damages.

each January 1 and July 1 in each year beginning with January 1, 2004, and at
such other times as the Trustee may request in writing, within thirty (30) days
after receipt by the Company of any such request (or such lesser time as the
Trustee may reasonably request in order to enable it to timely provide any
notice to be provided by it hereunder), a list in such form as the Trustee may
reasonably require of the names and addresses of the registered 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 5.02.   PRESERVATION AND DISCLOSURE OF LISTS. (a) The Trustee
shall preserve, in as current a form as is reasonably practicable, all
information as to the names and addresses of the holders of Notes contained in
the most recent list furnished to it as provided in Section 5.01 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 list furnished to it as
provided in Section 5.01 upon receipt of a new list so 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 the Company and the Trustee that neither the Company nor the Trustee nor
any agent of either of them shall be held accountable by reason of any
disclosure of information as to names and addresses of holders of Notes made
pursuant to the Trust Indenture Act.

          SECTION 5.03.   REPORTS BY TRUSTEE. (a) Within sixty (60) days after
December 30 of each year commencing with the year 2003, the Trustee shall
transmit to holders of Notes such reports dated as of December 30 of the year in

Indenture as shall be required, if any, 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 5.04.   REPORTS BY COMPANY. The Company shall file with the
Trustee and transmit to holders of the Notes, such information, documents and
other reports as it is required to file with the Commission pursuant to Section

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

                                       30

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

     shall become due and payable, and continuance of such default for a period
     of thirty (30) days; or

          (b)     default in the payment of the principal of any of the Notes as

          (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 6.01
     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 8.04; or

          (d)     the entry by a court having jurisdiction in the premises of
     (A) a decree or order for relief in respect of the Company in an
     involuntary case or proceeding under any applicable Federal or State
     bankruptcy, insolvency, reorganization or other similar law or (B) a decree
     or order adjudging the Company a bankrupt or insolvent, or approving as
     properly filed a petition seeking reorganization, arrangement, adjustment
     or composition of or in respect of the Company under any applicable Federal
     or State law, or appointing a custodian, receiver, liquidator, assignee,
     trustee, sequestrator or other similar official of the Company or of any
     substantial part of the property of the Company, or ordering the winding up
     or liquidation of the affairs of the Company, and the continuance of any
     such decree or order for relief or any such other decree or order unstayed
     and in effect for a period of 60 consecutive days; or

          (e)     the commencement by the Company of a voluntary case or
     proceeding under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or of any other case or proceeding to
     be adjudicated a bankrupt or insolvent, or the consent by the Company to
     the entry of a decree or order for relief in respect of the

                                       31
<Page>

     Company in an involuntary case or proceeding under any applicable Federal
     or State bankruptcy, insolvency, reorganization or other similar law or to
     the commencement of any bankruptcy or insolvency case or proceeding against
     the Company or the filing by the Company of a petition or answer or consent
     seeking reorganization or relief under any applicable Federal or State law,
     or the consent by the Company to the filing of such a petition or to the
     appointment of or taking possession by a custodian, receiver, liquidator,
     assignee, trustee, sequestrator or similar official of the Company or of
     any substantial part of the property of the Company, or the making by the
     Company of an assignment for the benefit of creditors, or the admission by
     the Company in writing of its inability to pay its debts generally as they
     become due, or the taking of corporate action by the Company in furtherance
     of any such action;

then, and in each and every such case (other than an Event of Default specified
in 6.01(d) or 6.01(e) that occurs 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 8.04, by notice in writing to the Company (and to the
Trustee if given by Noteholders) specifying the respective Event of Default and
stating that it is a "notice of acceleration", may declare the principal of all
the Notes and the interest accrued thereon to be due and payable immediately,
and upon receipt of such notice the same shall become and shall be immediately
due and payable. If an Event of Default specified in 6.01(d) or 6.01(e)
involving the Company occurs, the principal of all the Notes and the interest
accrued thereon shall be immediately and automatically due and payable without
necessity of further action. This provision, however, is subject to the
conditions that if, at any time after the principal of the 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 of interest upon all Notes and the principal of any and
all Notes which shall have become due otherwise than by acceleration (with
interest on overdue installments of interest (to the extent that payment of such
interest is enforceable under applicable law) and on such principal at the rate
borne by the Notes plus 1%, to the date of such payment or deposit) and amounts
due to the Trustee pursuant to Section 7.07, and if any and all defaults under
this Indenture, other than the nonpayment of principal of, and accrued interest
on, Notes which shall have become due by acceleration, shall have been cured or
waived pursuant to Section 6.07, 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 in writing a Responsible Officer of the
Trustee, promptly upon becoming aware thereof, of any Event of Default.

          In case the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
because of such waiver or rescission and annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every such case
the Company, the holders of Notes, and the Trustee shall be restored
respectively to their several positions and rights hereunder, and all rights,
remedies and

                                       32
<Page>

powers of the Company, the holders of Notes, and the Trustee shall continue as
though no such proceeding had been taken.

          SECTION 6.02.   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 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 any of the Notes as and when the same shall have become due and payable,
whether at maturity of the Notes or in connection with any redemption or
repurchase, by or under this Indenture 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 or interest, as the case may be, with interest upon the
overdue principal and (to the extent that payment of such interest is
enforceable under applicable law) upon the overdue installments of interest at
the rate borne by the Notes, plus 1% 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 7.07. Until such
demand by the Trustee, the Company may pay the principal of, and interest on,
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 6.02,
shall be entitled and empowered, by intervention in such proceedings or
otherwise, to file and prove a claim or claims for the whole amount of principal
and interest 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 7.07, and any receiver, assignee or
trustee in bankruptcy or reorganization, liquidator, custodian or similar
official is hereby

                                       33
<Page>

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 and expenses incurred by it up to the date of such distribution.

          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 agents
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 6.03.   APPLICATION OF MONIES COLLECTED BY TRUSTEE. Any monies
collected by the Trustee pursuant to this Article 6 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 7.07;

                  SECOND: In case the principal of the outstanding Notes shall
          not have become due and be unpaid, to the payment of interest on 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 at the rate borne by the Notes plus 1%, such payments to be
          made ratably to the Persons entitled thereto;

                  THIRD: 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 interest, with interest on the overdue principal and (to
          the extent that such interest has been collected by the Trustee) upon
          overdue installments of interest at the rate borne by the Notes plus
          1% to the Persons entitled thereto, 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 interest without
          preference or priority of principal, over interest, or of interest
          over principal, 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 accrued and unpaid interest;
          and

                                       34
<Page>

                  FOURTH: To the payment of the remainder, if any, to the
          Company or any other Person lawfully entitled thereto.

          SECTION 6.04.   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 reasonable 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 6.07; 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 6.04, 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 (including the redemption or repurchase price upon redemption
or repurchase pursuant to Article 3), and accrued interest on such Note, on or
after the respective due dates expressed in such Note or in the case of a
redemption or repurchase, on the redemption date or Repurchase Date, as the case
may be, 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 6.05.   PROCEEDINGS BY TRUSTEE. In case of an Event of
Default, the Trustee may, in its discretion, but shall not be required to,
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.

                                       35
<Page>

          SECTION 6.06.   REMEDIES CUMULATIVE AND CONTINUING. Except as provided
in Section 2.06, all powers and remedies given by this Article 6 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
6.04, every power and remedy given by this Article 6 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 6.07.   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 8.04
shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee; PROVIDED that (a) such direction shall not be in
conflict with any rule of law or with this Indenture, (b) the Trustee may take
any other action 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 or of the Trustee. The holders of a majority in
aggregate principal amount of the Notes at the time outstanding determined in
accordance with Section 8.04 may, on behalf of the holders of all of the Notes,
waive any past or existing default or Event of Default hereunder and its
consequences except (i) a past or existing default in the payment of interest
on, or the principal of, the Notes (including in connection with an offer to
purchase); PROVIDED however that holders of a majority in aggregate principal
amount of the then outstanding Notes may rescind an acceleration and its
consequences, including any related payment default that resulted from such
acceleration in accordance with Section 6.01, (ii) a failure by the Company to
convert any Notes into Common Stock, (iii) a default in the payment of the
redemption price pursuant to Article 3, (iv) a default in the payment of the
purchase price pursuant to Article 3 or (v) a default in respect of a covenant
or provisions hereof which under Article 10 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 cured or waived as permitted by this Section
6.07, 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 for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

          SECTION 6.08.   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

                                       36
<Page>

such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in such suit, having
due regard to the merits and good faith of the claims or defenses made by such
party litigant; PROVIDED that the provisions of this Section 6.08 (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 10% in principal amount of the Notes at the time outstanding
determined in accordance with Section 8.04, or to any suit instituted by any
Noteholder for the enforcement of the payment of the principal of, 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 14.

                                   ARTICLE VII
                                   THE TRUSTEE

          SECTION 7.01.   CERTAIN DUTIES AND RESPONSIBILITIES. The duties and
responsibilities of the Trustee shall be as provided by the Trust Indenture Act
(as if such Act applied). Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so 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 7.01.

          SECTION 7.02.   NOTICE OF DEFAULTS. Subject to the provisions of
Section 7.03(i), the Trustee shall give the Noteholders notice of any default
hereunder as and to the extent provided by the Trust Indenture Act (as if such
Act applied); PROVIDED, HOWEVER, that except in the case of default in the
payment of the principal of, or interest 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. For
the purpose of this Section 7.02, the term "default" means any event which is,
or after notice or lapse of time or both would become, an Event of Default.

provisions of Section 7.01:

          (a)     the Trustee may conclusively rely and shall be protected in

     Secretary or an Assistant Secretary of the Company;

          (c)     whenever in the administration of this Indenture the Trustee

     the rights or powers vested in it by this Indenture at the request or

     expenses (including reasonable attorney's fees and expenses) and
     liabilities which might be incurred by it in compliance with such request
     or direction;

          (f)     the Trustee shall not be bound to make any investigation into

     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may, but shall not be
     required to, 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;

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

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

          (i)     the Trustee shall not be deemed to have knowledge of any

     fact such a default is received by the Trustee at the Corporate Trust
     Office of the Trustee, and such notice references the Notes and this
     Indenture; and

          (j)     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.

          SECTION 7.04.   NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF NOTES. 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 their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture, the Notes.
The Trustee shall not be accountable for the use or application by the Company
of any Notes or the proceeds thereof.

          SECTION 7.05.   MAY HOLD NOTES. The Trustee, any authentication agent,
any paying agent, any conversion agent, any Note registrar or any other agent of
the Company or the Trustee, in its individual or any other capacity, may become
the owner or pledgee of Notes, and, subject to Sections 7.08 and 7.13, may
otherwise deal with the Company and any other obligor upon the Notes with the
same rights it would have if it were not Trustee, authentication agent, paying
agent, conversion agent or Note registrar.

          SECTION 7.06.   MONIES TO BE HELD IN TRUST. 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 otherwise agreed in writing with the
Company.

          SECTION 7.07.   COMPENSATION AND REIMBURSEMENT. The Company agrees (1)
to pay to the Trustee from time to time such compensation as shall be agreed in
writing between the Company and the Trustee for all services rendered by it
hereunder (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust); (2) except as
otherwise expressly provided herein, to reimburse the Trustee upon its request
for all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any provision of this Indenture (including the
reasonable compensation and the expenses and disbursements of its agents and
counsel), except any such expense, disbursement or advance as may be
attributable to its gross negligence or bad faith; and (3) to indemnify each of
the Trustee and any predecessor Trustee for, and to hold it harmless against,
any and all loss, liability, damage, claim or expense, including taxes (other
than taxes based on the income of the Trustee) incurred without gross negligence
or bad faith on its part, arising out of or in connection with the acceptance or
administration of this trust, including the costs and expenses, including
reasonable attorney's fees and expenses, of defending itself against any claim
(whether asserted by the Company, a Noteholder or any other Person) or liability
in connection with the exercise or performance of any of its powers or duties
hereunder.

          The Trustee shall have a lien prior to the Notes as to all property
and funds held by it hereunder for any amount owing it or any predecessor
Trustee pursuant to this Section 7.07, except with respect to funds held in
trust for the benefit of the holders of particular Notes.

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 6.01(d) or 6.01(e), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or
other similar law.

                                       39

          SECTION 7.08.   DISQUALIFICATION; CONFLICTING INTERESTS. If the
Trustee has or shall acquire a conflicting interest within the meaning of the
Trust Indenture Act, the Trustee shall either eliminate such interest or resign,
to the extent and in the manner provided by, and subject to the provisions of
and this Indenture.

          SECTION 7.09.   CORPORATE TRUSTEE REQUIRED; ELIGIBILITY. 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 and has an office located in the Borough of
Manhattan, The City of New York. If such Person publishes reports of condition
at least annually, pursuant to law or to the requirements of its supervising or
examining authority, then for the purposes of this Section 7.09, 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 7.09, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article 7.

          SECTION 7.10.   RESIGNATION AND REMOVAL OF TRUSTEE; APPOINTMENT OF
SUCCESSOR. (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article 7 shall become effective until the
acceptance of appointment by the successor Trustee under Section 7.11.

          (b)     The Trustee may resign at any time by giving written notice
thereof to the Company. If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

          (c)     The Trustee may be removed at any time by act of the holders
of a majority in principal amount of the outstanding Notes, delivered to the
Trustee and the Company. If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 days after the giving of
such notice of removal, the Trustee being removed may petition any court of
competent jurisdiction for the appointment of a successor.

          (d)     If at any time:

                  (i)     the Trustee shall fail to comply with Section 7.08
          after written request therefor by the Company or by any Noteholder who
          has been a bona fide holder of a Note for at least six months, or

                  (ii)    the Trustee shall cease to be eligible under Section
          7.09 and shall fail to resign after written request therefor by the
          Company or by any such Noteholder, or

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

                                       40
<Page>

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 6.08, 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.

          (e)     If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a resolution of the Board of Directors, shall promptly appoint a
successor Trustee. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee shall be
appointed by act of the holders of a majority in principal amount of the
outstanding Notes delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment, become the successor Trustee and supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed
by the Company or the holders and accepted appointment in the manner hereinafter
provided, any Noteholder who has been a bona fide holder of a Note for at least
six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee.

          (f)     The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to all
holders in the manner provided in Section 15.03. Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office.

          SECTION 7.11.   ACCEPTANCE OF APPOINTMENT OF SUCCESSOR. Every
successor Trustee appointed hereunder shall execute, acknowledge and deliver to
the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on written request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder. Upon request of any such successor Trustee, the
Company shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts.

          No successor trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article 7.

          Upon acceptance of appointment by a successor trustee as provided in
this Section 7.11, the Company (or the former trustee, at the written direction
of the Company) shall mail or cause to be mailed notice of the succession of
such trustee hereunder to the holders of Notes at their addresses as they shall
appear on the Note register. If the Company fails to mail such

                                       41
<Page>

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 7.12.   MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS. 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 the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article 7,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Notes shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Notes so authenticated with the same effect as if
such successor Trustee had itself authenticated such Notes.

          SECTION 7.13.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. 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 (as if such Act applied) regarding the collection of the
claims against the Company or any such other obligor.

                                  ARTICLE VIII
                                 THE NOTEHOLDERS

          SECTION 8.01.   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 9, 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 be not more than fifteen
(15) days prior to the date of commencement of initial solicitation of such
action without giving effect to any extension or amendment of such action or
solicitation.

          SECTION 8.02.   PROOF OF EXECUTION BY NOTEHOLDERS. Subject to the
provisions of Sections 7.03 and 9.05, 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 9.06.

                                       42
<Page>

          SECTION 8.03.   WHO ARE DEEMED ABSOLUTE OWNERS. The Company, the
Trustee, any authenticating agent, 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, and interest on, such Note, for conversion of such
Note and for all other purposes; and neither the Company nor the Trustee nor any
authenticating agent, 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 8.04.   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 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 faith may be
regarded as outstanding for the purposes of this Section 8.04 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 good faith 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 7.03, 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 8.05.   REVOCATION OF CONSENTS, FUTURE HOLDERS BOUND. At any
time prior to (but not after) the evidencing to the Trustee, as provided in
Section 8.01, 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 8.02, revoke such action so far as
concerns such Note. Except as aforesaid, any such action taken by the holder of
any Note shall be a continuing action and 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. An amendment, supplement or waiver becomes effective
in accordance with its terms and thereafter binds every holder.

                                       43

                                   ARTICLE IX
                             MEETINGS OF NOTEHOLDERS

          SECTION 9.01.   PURPOSE OF MEETINGS. A meeting of Noteholders may be
called at any time and from time to time pursuant to the provisions of this
Article 9 for any of the following purposes:

                  (1)     to give any notice to the Company or to the Trustee or
          to give any directions to the Trustee permitted under this Indenture,
          or to consent to the waiving of any default or Event of Default
          hereunder and its consequences, or to take any other action authorized
          to be taken by Noteholders pursuant to any of the provisions of
          Article 6;

                  (2)     to remove the Trustee and nominate a successor trustee
          pursuant to the provisions of Article 7;

                  (3)     to consent to the execution of an indenture or
          indentures supplemental hereto pursuant to the provisions of Section
          10.02; or

                  (4)     to take any other action authorized to be taken by or
          on behalf of the holders of any specified aggregate principal amount
          of the Notes under any other provision of this Indenture or under
          applicable law.

          SECTION 9.02.   CALL OF MEETINGS BY TRUSTEE. The Trustee may at any
time call a meeting of Noteholders to take any action specified in Section 9.01,
to be held at such time and at such place as the Trustee shall determine. Notice
of every meeting of the Noteholders, setting forth the time and the place of
such meeting and in general terms the action proposed to be taken at such
meeting and the establishment of any record date pursuant to Section 8.01, 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 9.03.   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 twenty-five (25%) in aggregate principal amount of the Notes
then outstanding, shall have requested the Trustee to call a meeting of
Noteholders, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have mailed the
notice of such meeting within twenty (20) days after receipt of such request,
then the Company or such Noteholders may determine the time and the place for
such meeting and may call such meeting to take any action authorized in Section
9.01, by mailing notice thereof as provided in Section 9.02.

                                       44
<Page>

          SECTION 9.04.   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 9.05.   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 9.03, 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 except that any meeting called by the Company shall be chaired by a
representative of the Company and any meeting called by the Trustee may, at the
Trustee's election, be chaired by the Trustee.

          Subject to the provisions of Section 8.04, 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. If any vote cast or
counted or proposed to be cast or counted is challenged on the ground that such
Note is not outstanding, or does not comply with the provisions of Section 9.04,
the chairman of the meeting shall determine whether the holder of such Note is
authorized to act. The chairman of the meeting shall have no right to vote other
than by virtue of Notes held by him or instruments in writing as aforesaid duly
designating him as the proxy to vote on behalf of other Noteholders. Any meeting
of Noteholders duly called pursuant to the provisions of Section 9.02 or 10.02
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.

          SECTION 9.06.   VOTING. The vote upon any resolution submitted to any
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 be representatives of the Trustee, and 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

                                       45
<Page>

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 9.02. 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, absent manifest error.

          SECTION 9.07.   NO DELAY OF RIGHTS BY MEETING. Nothing contained in
this Article 9 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 10.01.  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 evidence the succession of another Person to the Company
     and the assumption by any such successor of the covenants of the Company
     pursuant to Article II; or

          (b)     to add to the covenants of the Company for the benefit of the
     Noteholders, or to surrender any right or power herein conferred upon the
     Company; or

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

          (d)     to cure any ambiguity, to correct or supplement any provision
     herein which may be inconsistent with any other provision herein, or to
     make any other provisions with respect to matters or questions arising
     under this Indenture, which shall not be inconsistent with the provisions
     of this Indenture; or

          (e)     to add to, change or eliminate any of the provisions of this
     Indenture to permit or facilitate the issuance of Global Notes and matters
     related thereto, PROVIDED that such action pursuant to this clause (e)
     shall not adversely affect the interests of the Holders in any material
     respect; or

          (f)     make provision with respect to the conversion rights of the
     holders of Notes pursuant to the requirements of Section 14.06 and the
     redemption obligations of the Company pursuant to the requirements of
     Section 3.05(e).

          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 10.01 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 10.02.

          Notwithstanding any other provision of the Indenture or the Notes, the
Registration Rights Agreement and the obligation to pay Liquidated Damages
thereunder may be amended, modified or waived in accordance with the provisions
of the Registration Rights Agreement.

          SECTION 10.02.  SUPPLEMENTAL INDENTURE WITH CONSENT OF NOTEHOLDERS.
With the consent (evidenced as provided in Article 8) 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 that no such supplemental indenture
shall (i) change the fixed maturity of any Note or reduce the rate or change the
time of payment of interest thereon or reduce the principal amount thereof or
reduce any amount payable on redemption or repurchase thereof or impair the
right of any Noteholder to institute suit for the payment thereof or make the
principal thereof or interest thereon payable in any coin or currency or payable
at any place other than that provided in this Indenture or the Notes, or change
the obligation of the Company to redeem any Note on a redemption date in a
manner adverse to the holders of Notes or change the obligation of the Company
to redeem any Note upon the happening of a Designated Event in a manner adverse
to the holders of Notes or change the obligation of the Company to repurchase
any Note on a Repurchase Date in a manner adverse to the holders of Notes or
reduce the Conversion Rate, otherwise than in accordance with the terms of this
Indenture, or impair the right to convert the Notes into Common Stock subject to
the terms set forth herein, including Section 14.06 or reduce the quorum or the
voting requirements under the Indenture, or modify any of the provisions of this
Section 10.02 or Section 6.07, except to increase any such percentage or to
provide that certain other provisions of this Indenture cannot be modified or
waived without the consent of the holder of each Note so affected, or change any
obligation of the Company to maintain an office or agency in the places and for
the purposes set forth in Section 4.01, 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 or to waive any past Event of Default, without the consent of the
holders of all Notes affected thereby.

                                       47
<Page>

          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 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 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 10.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

          SECTION 10.03.  EFFECT OF SUPPLEMENTAL INDENTURE. Upon the execution
of any supplemental indenture pursuant to the provisions of this Article 10,
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 10.04.  NOTATION ON NOTES. Notes authenticated and delivered
after the execution of any supplemental indenture pursuant to the provisions of
this Article 10 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 Company, 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 15.11) and delivered in
exchange for the Notes then outstanding, upon surrender of such Notes then
outstanding.

          SECTION 10.05.  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 as
conclusive evidence that any supplemental indenture executed pursuant hereto
complies with the requirements of this Article 10.

                                   ARTICLE XI
                           MERGER, CONSOLIDATION, ETC.

          SECTION 11.01.  MERGERS, CONSOLIDATIONS AND CERTAIN TRANSFERS, LEASES
AND ACQUISITIONS OF ASSETS. The Company shall not consolidate with or merge into
any other Person or convey, transfer or lease its properties and assets
substantially as an entirety to any Person, unless:

          (a)     in case the Company shall consolidate with or merge into
     another Person or convey, transfer or lease its properties and assets
     substantially as an entirety to any

                                       48
<Page>

     Person, the Person formed by such consolidation or into which the Company
     is merged or the Person which acquires by conveyance or transfer, or which
     leases, the properties and assets of the Company substantially as an
     entirety shall be a corporation, partnership or trust, shall be organized
     and validly existing under the laws of the United States of America, any
     State thereof or the District of Columbia and shall expressly assume, by an
     indenture supplemental hereto, executed and delivered to the Trustee, in
     form satisfactory to the Trustee, the due and punctual payment of the
     principal of, and interest on, all the Notes and the performance or
     observance of every covenant and obligation of this Indenture, the Notes
     and the Registration Rights Agreement on the part of the Company to be
     performed or observed; and

          (b)     immediately after giving effect to such transaction, no Event
     of Default, and no event which, after notice or lapse of time or both,
     would become an Event of Default, shall have happened and be continuing.

          SECTION 11.02.  SUCCESSOR TO BE SUBSTITUTED. Upon any consolidation of
the Company with, or merger of the Company into, any other Person or any
conveyance, transfer or lease of the properties and assets of the Company
substantially as an entirety in accordance with Section 11.01, the successor
Person formed by such consolidation or into which the Company is merged or to
which such conveyance, transfer or lease is made shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor Person had been named
as the Company herein, and thereafter, except in the case of a lease, the
predecessor Person shall be relieved of all obligations and covenants under this
Indenture and the Notes.

          SECTION 11.03.  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 11.

                                   ARTICLE XII
                     SATISFACTION AND DISCHARGE OF INDENTURE

          SECTION 12.01.  DISCHARGE OF INDENTURE. When (a) the Company shall
deliver to the Trustee for cancellation all Notes theretofore authenticated
(other than any Notes that have been destroyed, lost or stolen and in lieu of or
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
redemption or repurchase of all of the Notes (other than any Notes that shall
have been mutilated, destroyed, lost or stolen and in lieu of or in substitution
for which other Notes shall have been authenticated and delivered) not
theretofore canceled or delivered to the Trustee for cancellation, including
principal and interest due or to become due to such date of maturity or
redemption date or Repurchase Date, as the case may be, accompanied by a
verification report, as to the sufficiency of the deposited amount, from an
independent certified

                                       49
<Page>

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, as the case may be, then this Indenture shall cease to be of
further effect (except in the case of clause (b) as to (i) remaining rights of
registration of transfer, substitution and exchange and conversion of Notes and
(ii) rights hereunder of Noteholders to receive payments of principal of, 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). The rights, obligations and immunities of the
Trustee hereunder shall survive any discharge pursuant to paragraph (a) and (b)
of this Section 12.01. The Trustee, on written demand of the Company accompanied
by an Officers' Certificate and an Opinion of Counsel as required by Section
11.05 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 reasonably and properly
rendered by the Trustee in connection with this Indenture or the Notes.

          SECTION 12.02.  DEPOSITED MONIES TO BE HELD IN TRUST BY TRUSTEE.
Subject to Section 12.04, all monies deposited with the Trustee pursuant to
Section 12.01, shall be held in trust for the sole benefit of the Noteholders,
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 the 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.

          SECTION 12.03.  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 12.04.  RETURN OF UNCLAIMED MONIES. Subject to the
requirements of applicable law and this Indenture, any monies deposited with or
paid to the Trustee for payment of the principal of, 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, 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 12.05.  REINSTATEMENT. If the Trustee or the paying agent is
unable to apply any money in accordance with Section 12.02 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 12.01 until such time as the Trustee or the paying
agent is permitted to apply all such money in accordance with Section 12.02;
PROVIDED that if the Company makes any payment of interest on or principal of
any Note following the

                                       50
<Page>

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 XIII
         IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

          SECTION 13.01.  INDENTURE AND NOTES SOLELY CORPORATE OBLIGATIONS. No
recourse for the payment of the principal of 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 XIV
                               CONVERSION OF NOTES

          SECTION 14.01.  RIGHT TO CONVERT. (a) Subject to and upon compliance
with the provisions of this Indenture, the holder of any Note shall have the
right, at such holder's option, to convert the principal amount of the Note, or
any portion of such principal amount which is a multiple of $1,000, into fully
paid and non-assessable shares of Common Stock (as such shares shall then be
constituted) at the Conversion Rate in effect at such time, by surrender of the
Note so to be converted in whole or in part, together with any required funds
under the circumstances described in this Section 14.01, in the manner provided
in Section 14.02. The Notes shall be convertible only upon the occurrence of one
of the following events:

          (i)     during any fiscal quarter commencing after September 30, 2003,
     if the Closing Sale Price exceeds 120% of the Conversion Price for at least
     20 Trading Days in the 30 consecutive Trading Day period ending on the last
     Trading Day of the immediately preceding fiscal quarter (it being
     understood for purposes of this Section 14.01(a)(i) that the Conversion
     Price in effect at the close of business on each of the 30 consecutive
     Trading Days should be used and such calculation shall give effect to any
     event referred to in Section 14.05 or 14.06 occurring during such 30
     Trading Day period);

          (ii)    during each of the five Business Day period immediately after
     any five consecutive Trading Day period in which the Trading Price per
     $1,000 principal amount of the Notes for each day of such five Trading Day
     period was less than 95% of the product of the Closing Sale Price on the
     applicable date and the Conversion Rate; PROVIDED, however, the Notes shall
     not be convertible pursuant to this Section 14.01(a)(ii) after July 15,
     2028 if on any Trading Day during such five Trading Day period the Closing
     Sale Price was between 100% and 120% of the then current Conversion Price
     (it being understood for purposes of this Section 14.01(a)(ii) that the
     Conversion Rate in effect at the close of business on each of the five
     consecutive Trading Days should be

                                       51
<Page>

     used and such calculation shall give effect to any event referred to in
     Section 14.05 or 14.06 occurring during such five Trading Day period);

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

          (iv)    as provided in Section (b) of this Section 14.01.

          Upon receipt by the Trustee of a demand for conversion from a
Noteholder pursuant to this Section, the Trustee (or other conversion agent
appointed by the Company) shall, on behalf of the Company, confirm (based on
information provided by the Company) whether the Notes shall be convertible as a
result of the occurrence of an event specified in clause (i) above, but, in any
event, the Company shall be obligated at all times to determine whether the
Notes shall be convertible as a result of the occurrence of an event specified
in clause (i) of this Section, and, if the Notes shall be convertible, the
Trustee (or other conversion agent appointed by the Company) shall promptly
deliver to the Company and the Trustee (if the Trustee is not the conversion
agent) written notice thereof. Whenever the Notes shall become convertible
pursuant to this Section 14.01, the Company or, at the Company's request, the
Trustee in the name and at the expense of the Company, shall notify the holders
of the event triggering such convertibility in the manner provided in Section
15.03, and the Company shall also publicly announce such information and publish
it on the Company's web site. Any notice so given shall be conclusively presumed
to have been duly given, whether or not the holder receives such notice.

          The Trustee (or other conversion agent appointed by the Company) shall
have no obligation to determine the Trading Price under clause (ii) of this
Section 14.01 unless the Company has requested such a determination; and the
Company shall have no obligation to make such request unless a holder provides
it with reasonable evidence that the Trading Price per $1,000 principal amount
of Notes would be less than 95% of the product of the Closing Sale Price and the
number of shares of Common Stock issuable upon conversion of $1,000 principal
amount of Notes. If such evidence is provided, the Company shall instruct the
Trustee (or other conversion agent) to determine the Trading Price of the Notes
beginning on the next Trading Day and on each successive Trading Day until the
Trading Price per $1,000 principal amount of Notes is greater than or equal to
95% of the product of the Closing Sale Price and the number of shares issuable
upon conversion of $1,000 principal amount of the Notes.

          (b)     In addition, if:

                  (i)     (A)     the Company distributes to all holders of its
     Common Stock rights or warrants entitling them (for a period expiring
     within 45 days of the record date for the determination of the stockholders
     entitled to receive such distribution) to subscribe for or purchase shares
     of Common Stock, at a price per share less than the average of the Closing
     Sale Price for the ten Trading Days immediately preceding, but not
     including, the date such distribution is first publicly announced by the
     Company, or

                                       52
<Page>

                  (B)     the Company distributes to all holders of its Common
          Stock, assets (including cash), debt securities or rights to purchase
          its securities, where the Fair Market Value of such distribution per
          share of Common Stock exceeds 5% of the Closing Sale Price on the
          Trading Day immediately preceding the date such distribution is first
          publicly announced by the Company,

          then, in either case, the Notes may be surrendered for conversion at
          any time on and after the date that the Company gives notice to the
          holders of such distribution, which shall be not less than 20 days
          prior to the Ex-Dividend Time for such distribution, until the earlier
          of the close of business on the Business Day immediately preceding,
          but not including, the Ex-Dividend Time or the date the Company
          publicly announces that such distribution will not take place;
          PROVIDED that no adjustment to the Conversion Rate or the ability of a
          holder of a Note to convert will be made if the holder will otherwise
          participate in such distribution without conversion; or

                  (ii)    the Company consolidates with, or merges with or into,
          another Person or is a party to a binding share exchange or conveys,
          transfers, sells, leases or otherwise disposes of all or substantially
          all of its properties and assets, in each case, pursuant to which our
          common stock would be converted into cash, securities or other
          property, then the Notes may be surrendered for conversion at any time
          from and after the date fifteen (15) days prior to the anticipated
          effective date of the transaction and ending on and including the date
          fifteen (15) days after the consummation of the transaction. The Board
          of Directors shall determine the anticipated effective date of the
          transaction, and such determination shall be conclusive and binding on
          the holders and shall be publicly announced by the Company and posted
          on its web site not later than two Business Day prior to such 15th
          day.

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

          (c)     A Note in respect of which a holder is electing to exercise
its option to require redemption upon a Designated Event pursuant to Section
3.05(a) or repurchase pursuant to Section 3.06 may be converted only if such
holder withdraws its election in accordance with Section 3.05(b) or Section
3.08, respectively. 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 14.

          SECTION 14.02.  CONVERSION PROCEDURES. To convert a Note, a holder
must (a) complete and manually sign the Conversion Notice or a facsimile of the
Conversion Notice (a "CONVERSION NOTICE") in the form set forth on the reverse
of the Note and deliver such notice to the conversion agent, (b) surrender the
Note to the conversion agent, (c) furnish appropriate endorsements and transfer
documents if required by the Registrar or the conversion agent, (d)

                                       53
<Page>

pay any transfer or similar tax, if required and (e) if required, pay funds
equal to the interest payable on the next interest payment date. The date,
within the time periods set forth in Section 14.01, on which the holder
satisfies all of those requirements is the "CONVERSION DATE." Except as provided
in Section 14.05(j), the Company shall deliver to the holder through the
conversion agent, no later than the third Business Day following the Conversion
Date, a certificate for the number of whole shares of Common Stock issuable upon
the conversion and, if applicable, cash in lieu of any fractional shares
pursuant to Section 14.03.

          In the case of a Global Note, the Conversion Notice shall be completed
by a Depositary participant on behalf of the beneficial holder. Conversion
Notices may be delivered and such Notes may be surrendered for conversion in
accordance with the applicable procedures of the Depositary as in effect from
time to time. In order to cause a Depositary participant to complete a
Conversion Notice, a beneficial holder must complete, or cause to be completed,
the appropriate instruction form for conversion pursuant to the Depositary's
book-entry conversion program. The Person in whose name the Common Stock
certificate is registered shall be deemed to be a shareholder of record at the
close of business on the applicable Conversion Date; PROVIDED, HOWEVER, that if
any such date is a date when the stock transfer books of the Company are closed,
such Person shall be deemed a shareholder of record as of the next date on which
the stock transfer books of the Company are open.

          No payment or adjustment shall be made for dividends on, or other
distributions with respect to, any Common Stock except as provided in this
Article 14. On conversion of a Note, except for conversion during the period
from the close of business on any record date immediately preceding any interest
payment date to the close of business on the Business Day immediately preceding
such interest payment date, in which case the holder on such record date shall
receive the interest payable on such interest payment date, that portion of
accrued and unpaid interest on the converted Note attributable to the period
from the most recent interest payment date (or, if no interest payment date has
occurred, from the date of original issuance of the Notes) through the
Conversion Date shall not be cancelled, extinguished or forfeited, but rather
shall be deemed to be paid in full to the holder thereof through delivery of the
Common Stock (together with the cash payment, if any, in lieu of fractional
shares) in exchange for the Note being converted pursuant to the provisions
hereof, and the Fair Market Value of such shares of Common Stock (together with
any such cash payment in lieu of fractional shares) shall be treated as issued,
to the extent thereof, first in exchange for accrued and unpaid interest accrued
through the Conversion Date and the balance, if any, of such Fair Market Value
of such Common Stock (and any such cash payment) shall be treated as issued in
exchange for the principal amount of the Note being converted pursuant to the
provisions hereof.

          If a holder converts more than one Note at the same time, the number
of shares of Common Stock issuable upon the conversion shall be based on the
aggregate principal amount of Notes converted.

          Upon surrender of a Note that is converted in part, the Company shall
execute, and the Trustee shall authenticate and deliver to the holder, a new
Note equal in principal amount to the principal amount of the unconverted
portion of the Note surrendered.

                                       54
<Page>

          Notes or portions thereof surrendered for conversion during the period
from the close of business on any record date immediately preceding any interest
payment date to the close of business on the Business Day immediately preceding
such interest payment date shall be accompanied by payment to the Company or its
order, in immediately available funds or other funds acceptable to the Company,
of an amount equal to the interest payable on such interest payment date with
respect to the principal amount of Notes or portions thereof being surrendered
for conversion; PROVIDED that no such payment need be made if (1) the Company
has specified a redemption date that occurs during the period from the close of
business on a record date to the close of business on the Business Day
immediately preceding the interest payment date to which such record date
relates, (2) the Company has specified a Designated Event Redemption Date during
such period or (3) any overdue interest exists on the Conversion Date with
respect to the Notes converted, but only to the extent of overdue interest.

          SECTION 14.03.  CASH PAYMENTS IN LIEU OF FRACTIONAL SHARES. No
fractional shares of Common Stock or scrip certificates 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 hereby) 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. For purposes of this Section 14.03, the "CURRENT
MARKET PRICE" of a share of Common Stock shall be the Closing Sale Price on the
last Business Day immediately preceding the day on which the Notes (or specified
portions thereof) are deemed to have been converted.

          SECTION 14.04.  CONVERSION RATE. Each $1,000 principal amount of the
Notes shall be convertible into the number of shares of Common Stock specified
in the form of Note (herein called the "CONVERSION RATE") attached as Exhibit A
hereto, subject to adjustment as provided in this Article 14.

          SECTION 14.05.  ADJUSTMENT OF CONVERSION RATE. The Conversion Rate
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 Rate shall be increased so that the same shall
     equal the rate determined by multiplying the Conversion Rate 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,

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

                                       55
<Page>

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

     such increase to become effective immediately after the opening of business
     on the day following the date fixed for such determination. If any dividend
     or distribution of the type described in this Section 14.05(a) is declared
     but not so paid or made, the Conversion Rate shall again be adjusted to the
     Conversion Rate that would then be in effect if such dividend or
     distribution had not been declared.

          (b)     In case the Company shall issue rights 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 Average Market Price on the date such issuance is first
     publicly announced by the Company, the Conversion Rate shall be increased
     so that the same shall equal the rate determined by multiplying the
     Conversion Rate in effect immediately prior to the date fixed for
     determination of stockholders entitled to receive such rights or warrants
     by a fraction,

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

                  (ii)    the denominator of which shall be the sum of the
          number of shares of Common Stock outstanding at the close of business
          on the date fixed for determination of stockholders entitled to
          receive such rights or warrants plus the number of shares that the
          aggregate offering price of the total number of shares so offered
          would purchase at such Average Market Price.

                  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 Rate shall be
     readjusted to the Conversion Rate 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. If such rights or warrants are not so issued, the Conversion
     Rate shall again be adjusted to be the Conversion Rate that would then be
     in effect if such issuance had not been so declared or made. In determining
     whether any rights or warrants entitle the holders to subscribe for or
     purchase shares of Common Stock at less than such Average 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.

                                       56
<Page>

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

          (d)     In case the Company shall, by dividend or otherwise,
     distribute to all holders of its Common Stock shares of any class of
     capital stock of the Company or evidences of its indebtedness or assets
     (including cash and securities, but excluding any rights or warrants
     referred to in Section 14.05(b), and excluding any dividend or distribution
     referred to in Section 14.05(a) (any of the foregoing hereinafter in this
     Section 14.05(d)) called the "DISTRIBUTION")), then, in each such case
     (unless the Company elects to reserve such Distribution 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 Distribution which such holder would have received if such
     holder had converted its Notes into Common Stock immediately prior to the
     Record Date), the Conversion Rate shall be increased so that the same shall
     be equal to the rate determined by multiplying the Conversion Rate in
     effect at the close of business on the Record Date with respect to such
     distribution by a fraction,

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

                  (ii)    the denominator of which shall be the Average Market
          Price on such Record Date less (A) in the case of Distributions other
          than cash, 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 such Distributions applicable to one share of Common Stock
          and (B) in the case of Distributions of cash, the amount of such
          Distributions applicable to one share of Common Stock,

     such adjustment to become effective immediately prior to the opening of
     business on the day following such Record Date; PROVIDED that if the then
     Fair Market Value (as so determined) of the portion of the Distribution so
     distributed applicable to one share of Common Stock is equal to or greater
     than the Average Market Price 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 Distribution such
     holder would have received had such holder converted each Note on the
     Record Date. A holder who converts a Note pursuant to Section 14.01(b)
     shall not be entitled to any adjustment to the Conversion Rate with respect
     to such Note so converted. If such dividend or distribution is not so paid
     or made, the Conversion Rate shall again be

                                       57
<Page>

     adjusted to be the Conversion Rate that would then be in effect if such
     dividend or distribution had not been declared. If the Board of Directors
     determines the Fair Market Value of any distribution for purposes of this
     Section 14.05(d) by reference to the actual or when issued trading market
     for any securities, it must in doing so consider the prices in such market
     over the same period used in computing the Average Market Price on the
     applicable Record Date. Notwithstanding the foregoing, if the Distribution
     distributed by the Company to all holders of its Common Stock consists of
     capital stock of, or similar equity interests in, a Subsidiary or other
     business unit, the Conversion Rate shall be increased so that the same
     shall be equal to the rate determined by multiplying the Conversion Rate in
     effect on the Record Date with respect to such distribution by a fraction:

                  (i)     the numerator of which shall be the sum of (x) the
          average Closing Sale Price over the ten consecutive Trading Day period
          (the "SPINOFF VALUATION PERIOD") commencing on and including the fifth
          Trading Day after the date on which "ex-dividend trading" commences on
          the Common Stock on the New York Stock Exchange or such other national
          or regional exchange or market on which the Common Stock is then
          listed or quoted and (y) the average 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) over the
          Spinoff Valuation Period of the portion of the Distribution so
          distributed applicable to one share of Common Stock; and

                  (ii)    the denominator of which shall be the average Closing
          Sale Price over the Spinoff Valuation Period,

     such adjustment to become effective immediately prior to the opening of
     business on the day following such Record Date; PROVIDED that the Company
     may in lieu of the foregoing adjustment make adequate provision so that
     each Noteholder shall have the right to receive upon conversion the amount
     of Distribution such holder would have received had such holder converted
     each Note on the Record Date with respect to such distribution.

                  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 14.05
     (and no adjustment to the Conversion Rate under this Section 14.05 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 Rate shall be
     made under this Section 14.05(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
     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

                                       58
<Page>

     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 Rate under this Section 14.05 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 Rate shall be readjusted upon such final redemption or
     repurchase to give effect to such distribution or Trigger Event, as the
     case may be, as though it were a cash distribution, equal to the per share
     redemption or repurchase price received by a holder or holders of Common
     Stock with respect to such rights 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 Rate shall be readjusted as
     if such rights and warrants had not been issued.

                  No adjustment of the Conversion Rate shall be made pursuant to
     this Section 14.05(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 14.05(d) and Section 14.05(a) and
     (b), any dividend or distribution to which this Section 14.05(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 Rate adjustment
     required by this Section 14.05(d) with respect to such dividend or
     distribution shall then be made) immediately followed by (2) a dividend or
     distribution of such shares of Common Stock or such rights or warrants (and
     any further Conversion Rate adjustment required by Sections 14.05(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 Section 14.05(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 14.05(a).

          (e)     (A) In case a tender or exchange offer made by the Company or
     any Subsidiary for all or any portion of the Common Stock (excluding any
     transactions solely

                                       59
<Page>

     involving odd lots of shares of 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 Closing Sale Price on the Trading Day
     next succeeding the Expiration Time, the Conversion Rate shall be increased
     so that the same shall equal the rate determined by multiplying the
     Conversion Rate in effect immediately prior to the Expiration Time by a
     fraction,

                  (i)     the numerator of which shall be the sum of (x) the
          Fair Market Value (determined as aforesaid) of the aggregate
          consideration payable to stockholders based on the acceptance (up to
          any maximum specified in the terms of the tender or exchange offer) of
          all shares validly tendered or exchanged and not withdrawn as of the
          Expiration Time (the shares deemed so accepted up to any such maximum,
          being referred to as the "PURCHASED SHARES") and (y) the product of
          the number of shares of Common Stock outstanding (less any Purchased
          Shares) at the Expiration Time and the Closing Sale Price on the
          Trading Day next succeeding the Expiration Time, and

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

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

                  (B)     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 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) exceeds the
     Closing Sale Price of a share of 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 Rate shall be increased so that the same shall
     equal the rate determined by multiplying the Conversion Rate in effect
     immediately prior to the Offer Expiration Time by a fraction,

                                       60
<Page>

                  (i)     the numerator of which shall be the sum of (x) the
          Fair Market Value (determined as aforesaid) of the aggregate
          consideration payable to the 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 Closing Sale Price on the Trading Day next
          succeeding the Offer Expiration Time, and

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

     such adjustment to become effective immediately prior to the opening of
     business on the day following the Offer Expiration Time. If 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 Rate
     shall again be adjusted to be the Conversion Rate that would then be in
     effect if such tender or exchange offer had not been made. Notwithstanding
     the foregoing, the adjustment described in this Section 14.05(e)(B) 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 11 or a binding
     share exchange.

          (f)     For purposes of this Section 14.05, the following terms shall
     have the meaning indicated:

                  (1)     "AVERAGE MARKET PRICE", as of any date of
          determination, shall mean the average of the daily Closing Sale Prices
          for the ten consecutive Trading Days immediately preceding (A) in the
          case of a determination pursuant to Section 14.05(b), the date such
          issuance or distribution is publicly announced and (B) otherwise, the
          earlier of such date of determination and the day before the "ex" date
          with respect to the issuance, distribution, subdivision or combination
          requiring such computation immediately prior to the date in question.
          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 Sale Price was obtained
          without the right to receive such issuance or distribution, and (2)
          when used with 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.

                                       61

                          If another issuance, distribution, subdivision or
          combination to which Section 14.05 applies occurs during the period
          applicable for calculating "Average Market Price" pursuant to the
          definition in the preceding paragraph, "Average Market Price" shall be
          calculated for such period in a manner determined by the Board of
          Directors to reflect the impact of such issuance, distribution,
          subdivision or combination on the Closing Sale Price during such
          period.

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

                  (3)     "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).

          (g)     The Company may make such increases in the Conversion Rate, in
     addition to those required by Section 14.05(a), (b), (c), (d) or (e) as the
     Board of Directors considers to be advisable to avoid or diminish any
     income tax to any holders of Common Stock or rights to purchase Common
     Stock resulting from any dividend or distribution of stock (or rights to
     acquire stock) or from any event treated as such for income tax purposes.

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

          (h)     No adjustment in the Conversion Rate shall be required unless
     such adjustment would require an increase or decrease of at least one
     percent (1%) in such rate; PROVIDED that any adjustments that by reason of
     this Section 14.05(h) are not required to be made shall be carried forward
     and taken into account in any subsequent adjustment. All calculations under
     this Article 14 shall be made by the Company and shall be made to the
     nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as
     the case may be. No adjustment need be made for rights to purchase Common
     Stock pursuant to a Company plan for reinvestment of dividends or interest
     or for any issuance of Common Stock or convertible or exchangeable
     securities or rights to purchase Common Stock or convertible or
     exchangeable securities.

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

          (j)     In any case in which this Section 14.05 provides that an
     adjustment shall become effective immediately after (1) a record date or
     Record Date for an event (including without limitation, any event described
     in Section 14.05(d)), (2) the date fixed for the determination of
     stockholders entitled to receive a dividend or distribution pursuant to
     Section 14.05(a), (3) a date fixed for the determination of stockholders
     entitled to receive rights or warrants pursuant to Section 14.05(b), or (4)
     the Expiration Time for any tender or exchange offer pursuant to Section
     14.05(e), (each a "DETERMINATION DATE"), the Company may elect to defer
     until the occurrence of the applicable 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 Event
     over and above the Common Stock issuable upon such conversion before giving
     effect to such adjustment and (y) paying to such holder any amount in cash
     in lieu of any fraction pursuant to Section 14.03. For purposes of this
     Section 14.05(j), the term "ADJUSTMENT EVENT" shall mean:

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

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

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

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

          (k)     For purposes of this Section 14.05, the number of shares of
     Common Stock at any time outstanding shall not include shares held in the
     treasury of the

                                       63
<Page>

     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 14.06.  EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR
SALE. If any of the following events occur, namely (i) any reclassification or
change of the outstanding shares of Common Stock (other than a subdivision or
combination to which Section 14.05(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, (iii) the Company is a party to a binding share exchange, or (iv)
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 providing that each 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, binding share exchange, sale or
conveyance by a holder of a number of shares of Common Stock issuable upon
conversion of such 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, binding share exchange, 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, binding share exchange, 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, binding share exchange, sale or conveyance is not the same for each
share of Common Stock in respect of which such rights of election shall not have
been exercised ("NONELECTING SHARE"), then for the purposes of this Section
14.06 the kind and amount of stock, other securities or other property or assets
(including cash) receivable upon such reclassification, change, consolidation,
merger, combination, binding share exchange, sale or conveyance for each
non-electing share shall be deemed to be the kind and amount so receivable per
share by a plurality of the non-electing shares). 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 14.

          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 2.05 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.

          Interest will not accrue on any cash into which the Notes are
convertible.

                                       64
<Page>

          If this Section 14.06 applies to any event or occurrence, Section
14.05 shall not apply.

          SECTION 14.07.  TAXES ON SHARES ISSUED. The issue of stock
certificates on conversions of Notes shall be made without charge to the
converting Noteholder for any documentary, stamp or similar issue or transfer
tax in respect of the issue thereof. The Company shall not, however, be required
to pay any such tax which may be payable in 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 14.08.  RESERVATION OF SHARES, SHARES TO BE FULLY PAID;
COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS; LISTING OF COMMON STOCK. The Company
shall provide, free from preemptive rights, out of its authorized but unissued
shares or shares held in treasury, sufficient shares of Common Stock to provide
for the conversion of the Notes from time to time as such Notes are presented
for conversion.

          Before taking any action which would cause an adjustment increasing
the Conversion Rate to an amount that would cause the Conversion Price to be
reduced below the then par value, if any, of 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 Rate.

          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 by the Company 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 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, 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 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 14.09.  RESPONSIBILITY OF TRUSTEE. The Trustee and any other
conversion agent shall not at any time be under any duty or responsibility to
any holder of Notes to determine the Conversion Rate or whether any facts exist
which may require any adjustment of the Conversion Rate, or with respect to the
nature or extent or calculation of any such adjustment when made, or with
respect 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 14. 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 14.06 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 14.06 or to any adjustment to be made with respect thereto, but,
subject to the provisions of Section 7.01, may accept as conclusive evidence of
the correctness of any such provisions, and shall be protected in relying upon,
the Officers' Certificate (which the Company shall be obligated to file with the
Trustee prior to the execution of any such supplemental indenture) with respect
thereto.

          SECTION 14.10.  NOTICE TO HOLDERS PRIOR TO CERTAIN ACTIONS. In case:

          (a)     the Company shall declare a dividend (or any other
     distribution) on its Common Stock that would require an adjustment in the
     Conversion Rate pursuant to Section 15.05; 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

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

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 2.05 of this Indenture, as promptly as possible but in any event at
least ten (10) days prior to the applicable date

                                       66
<Page>

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, liquidation or winding up.
Failure to give such notice, or any defect therein, shall not affect the
legality or validity of such dividend, distribution, authorization, grant,
reclassification, reorganization, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up.

          SECTION 14.11.  RIGHTS ISSUED IN RESPECT OF COMMON STOCK ISSUED UPON
CONVERSION. Each share of Common Stock issued upon conversion of Notes pursuant
to this Article 14 shall be entitled to receive the appropriate number of common
stock or preferred stock purchase rights, as the case may be (the "RIGHTS"), if
any, that shares of Common Stock are entitled to receive and the certificates
representing the Common Stock issued upon such conversion shall bear such
legends, if any, in each case as may be provided by the terms of any shareholder
rights agreement adopted by the Company, as the same may be amended from time to
time (in each case, a "RIGHTS AGREEMENT"). Provided that such Rights Agreement
requires that each share of Common Stock issued upon conversion of Notes at any
time prior to the distribution of separate certificates representing the Rights
be entitled to receive such Rights, then, notwithstanding anything else to the
contrary in this Article 14 there shall not be any adjustment to the conversion
privilege or Conversion Rate as a result of the issuance of Rights, but an
adjustment to the Conversion Rate shall be made with respect to Notes then
outstanding pursuant to Section 14.05(d) (to the extent required thereby) upon
the separation of the Rights from the Common Stock.

                                   ARTICLE XV
                            MISCELLANEOUS PROVISIONS

          SECTION 15.01.  PROVISIONS BINDING ON COMPANY'S SUCCESSORS. All the
covenants, stipulations, promises and agreements by the Company contained in

          SECTION 15.02.  OFFICIAL ACTS BY SUCCESSOR CORPORATION. Any act or
proceeding by any provision of this Indenture authorized or required to be done
or performed by any board, committee or officer of the Company shall and may be
done and performed with like force and effect by the like board, committee or
officer of any Person that shall at the time be the lawful sole successor of the
Company.

          SECTION 15.03.  ADDRESSES FOR NOTICES, ETC. Any notice or demand which
by any provision of this Indenture is required or permitted to be given or
served by the Trustee or by the holders of Notes on the Company shall be deemed
to have been sufficiently given or made, for all purposes, if given or served by
being deposited postage prepaid by registered or certified mail in a post office
letter box addressed (until another address is filed by the Company with the
Trustee) to JetBlue Airways Corporation, 118-29 Queens Boulevard, Forest Hills,

to or upon the Trustee shall be deemed to have been sufficiently given or made,
for all purposes, if given or served by being deposited, postage prepaid, by
registered or certified mail in a post office letter box addressed to the

          The Trustee, by notice to the Company, may designate additional or
different addresses for subsequent notices or communications.

          Any notice or communication mailed to a Noteholder shall be mailed to
him by first class mail, postage prepaid, at his address as it appears on the
Note register and shall be sufficiently given to him if so mailed within the
time prescribed.

          Failure to mail a notice or communication to a Noteholder or any
defect in it shall not affect its sufficiency with respect to other Noteholders.
If a notice or communication is mailed in the manner provided above, it is duly
given, whether or not the addressee receives it.

          SECTION 15.04.  GOVERNING LAW. This Indenture and each Note shall be
deemed to be a contract made under the laws of the State of New York, and for
all purposes shall be construed in accordance with the laws of the State of New
York without reference to its principles of conflict of laws.

          SECTION 15.05.  EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT,
CERTIFICATES TO TRUSTEE. Upon any application or demand by the Company to the
Trustee to take any action under any of the provisions of this Indenture, the
Company shall furnish to the Trustee an Officers' Certificate stating that all
conditions precedent, if any, provided for in this Indenture relating to the
proposed action have been complied with, and an Opinion of Counsel stating that,
in the opinion of such counsel, all such conditions precedent have been complied
with.

          Each certificate or opinion provided for in this Indenture and

provided for in this Indenture shall include: (1) a statement that the person
making such certificate or opinion has read such covenant or condition; (2) a

          SECTION 15.06.  LEGAL HOLIDAYS. In any case in which the date of
maturity of interest on or principal of the Notes or the redemption date or
Repurchase Date of any Note will not be a Business Day, then payment of such
interest on or principal of the Notes need not be made on such date, but may be
made on the next succeeding Business Day with the same force and effect as if
made on the date of maturity or the redemption date or Repurchase Date, and no
interest shall accrue for the period from and after such date.

          SECTION 15.07.  TRUST INDENTURE ACT. This Indenture is hereby made
subject to, and shall be governed by, the provisions of the Trust Indenture Act
required to be part of and to govern indentures qualified under the Trust
Indenture Act; PROVIDED that unless otherwise

                                       68
<Page>

required by law, notwithstanding the foregoing, this Indenture and the Notes
issued hereunder shall not be subject to the provisions of subsections (a)(1),
(a)(2), and (a)(3) of Section 314 of the Trust Indenture Act as now in effect or
as hereafter amended or modified; PROVIDED FURTHER that this Section 15.07 shall
not require this Indenture or the Trustee to be qualified under the Trust
Indenture Act prior to the time such qualification is in fact required under the
terms of the Trust Indenture Act, nor shall it constitute any admission or
acknowledgment by any party to the Indenture that any such qualification is
required prior to the time such qualification is in fact required under the
terms of the Trust Indenture Act. If any provision hereof limits, qualifies or
conflicts with another provision hereof which is required to be included in an
indenture qualified under the Trust Indenture Act, such required provision shall
control.

          SECTION 15.08.  NO SECURITY INTEREST CREATED. Nothing in this
Indenture or in the Notes, expressed or implied, shall be construed to
constitute a security interest under the Uniform Commercial Code or similar
legislation, as now or hereafter enacted and in effect, in any jurisdiction in
which property of the Company or its subsidiaries is located.

          SECTION 15.09.  BENEFITS OF INDENTURE. Nothing in this Indenture or in
the Notes, express or implied, shall give to any Person, other than the parties
hereto, any paying agent, any authenticating agent, conversion agent, any Note
registrar and their successors hereunder and the holders of Notes any benefit or
any legal or equitable right, remedy or claim under this Indenture.

          SECTION 15.10.  TABLE OF CONTENTS, HEADINGS, ETC. The table of
contents and the titles and headings of the Articles and Sections of this
Indenture have been inserted for convenience of reference only, are not to be
considered a part hereof, and shall in no way modify or restrict any of the
terms or provisions hereof.

          SECTION 15.11.  AUTHENTICATING AGENT. The Trustee may appoint an
authenticating agent that shall be authorized to act on its behalf, and subject
to its direction, in the authentication and delivery of Notes in connection with
the original issuance thereof and transfers and exchanges of Notes hereunder,
including under Sections 2.04, 2.05, 2.06, 2.07, 3.03 and 3.05, as fully to all
intents and purposes as though the authenticating agent had been expressly
authorized by this Indenture and those Sections to authenticate and deliver
Notes. For all purposes of this Indenture, the authentication and delivery of
Notes by the authenticating agent shall be deemed to be authentication and
delivery of such Notes "by the Trustee" and a certificate of authentication
executed on behalf of the Trustee by an authenticating agent shall be deemed to
satisfy any requirement hereunder or in the Notes for the Trustee's certificate
of authentication. Such authenticating agent shall at all times be a Person
eligible to serve as trustee hereunder pursuant to Section 7.09.

          Any corporation into which any authenticating agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any authenticating agent
shall be a party, or any corporation succeeding to the corporate trust business
of any authenticating agent, shall be the successor of the authenticating agent
hereunder, if such successor corporation is otherwise eligible under this
Section 15.11, 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.

                                       69
<Page>

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

                             FORM OF REVERSE OF NOTE

                           JETBLUE AIRWAYS CORPORATION

                     3 1/2% CONVERTIBLE SENIOR NOTE DUE 2033

          This Note is one of a duly authorized issue of Notes of the Company,
designated as its 3 1/2% Convertible Notes Due 2033 (herein called the "NOTES"),
limited in aggregate principal amount to $175,000,000, issued and to be issued
under and pursuant to an Indenture dated as of July 15, 2003 (herein called the
"INDENTURE"), between the Company and Wilmington Trust Company, 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 shall have occurred and be continuing, the
principal of, and accrued interest 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 at least 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 that no such
supplemental indenture shall (i) change the fixed maturity of any Note, or
reduce the rate or change the time of payment of interest thereon, or reduce the
principal amount thereof, or reduce any amount payable on redemption or
repurchase thereof, or impair the right of any Noteholder to institute suit for
the payment thereof, or make the principal thereof or interest thereon payable
in any coin or currency or payable at any place other than that provided in the
Indenture or the Notes, or change the obligation of the Company to redeem any
Note on a redemption date in a manner adverse to the holders of Notes, or change
the obligation of the Company to redeem any Note upon the happening of a
Designated Event in a manner adverse to the holders of Notes, or change the
obligation of the Company to repurchase any Note on a Repurchase Date in a
manner adverse to the holders of Notes, or reduce the Conversion Rate otherwise
than in accordance with the terms of the Indenture or otherwise impair the right
to convert the Notes into Common Stock subject to the terms set forth herein,
including Section 14.06, thereof or reduce the quorum or the voting requirements
under the Indenture, or modify any of the provisions of Section 10.02 or Section
6.07, except to increase any such percentage or to provide that certain other
provisions of this Indenture cannot be modified or waived without the consent of
the holder of each Note so affected, or change any obligation of the Company to
maintain an office or agency in the places and for the purposes set forth in
Section 4.01 thereof, 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 or to waive
any past Event of Default, without the consent of the holders of each Notes
affected thereby. Subject to the provisions of the Indenture, the holders of a
majority in aggregate principal amount of the Notes

                                       A-6
<Page>

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, 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, or a default in
the payment of the repurchase price on a Repurchase Date, or a default in
respect of a covenant or provisions of the Indenture which under Article 10 of
the Indenture cannot be modified or amended 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.

          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 interest 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 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.

          At any time on or after July 18, 2006 and prior to July 18, 2008, the
Company may redeem any of the Notes at a redemption price of 100% of the
principal amount of the Notes being redeemed, plus accrued and unpaid interest,
if the Closing Sale Price on the Nasdaq National Market has exceeded 150% of the
Conversion Price for at least 20 Trading Days in any period of 30 consecutive
Trading Days.

          At any time on or after July 18, 2008 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 but not more than 60 days
before the redemption date to the holders of Notes at their last registered
addresses, all as provided in the Indenture, at a redemption price equal to 100%
of the principal amount of the Notes to be redeemed, together with accrued and
unpaid interest to, but excluding, the redemption date; PROVIDED that if the
redemption date is on a January 15 or July 15, then the interest payable on such
date shall be paid to the holder of record on the preceding January 1 or July 1,
respectively.

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

                                       A-7
<Page>

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

          If a Designated Event occurs at any time prior to maturity of the
Notes, this Note will be redeemable on a Designated Event Redemption Date, 30
days after notice thereof, at the option of the holder of this Note at a
redemption price equal to 100% of the principal amount thereof, together with
accrued interest to (but excluding) the redemption date; PROVIDED that if such
Designated Event Redemption Date is a January 15 or July 15, the interest
payable on such date shall be paid to the holder of record of this Note on the
preceding January 1 or July 1, 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 Designated Event and of the
redemption right arising as a result thereof on or before the 10th day after the
occurrence of such Designated Event. 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 the terms of the Indenture, such
Note with the form entitled "Option to Elect Repayment Upon a Designated Event"
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
Designated Event (or if such 30th day is not a Business Day, the immediately
succeeding Business Day).

          Subject to the terms and conditions of the Indenture, the Company
shall become obligated to purchase, at the option of the holder, all or any
portion of the Notes held by such holder on July 15, 2008, July 15, 2013, July
15, 2018, July 15, 2023 and July 15, 2028, in whole multiples of $1,000 at a
purchase price of 100% of the principal amount, plus any accrued and unpaid
interest, on such Note up to the Repurchase Date. To exercise such right, a
holder shall deliver to the Company such Note with the form entitled "Repurchase
Notice" on the reverse thereof duly completed, together with the Note, duly
endorsed for transfer, at any time from the opening of business on the date that
is 20 Business Days prior to such Repurchase Date until the close of business on
the Repurchase Date, and shall deliver the Notes to the Trustee (or other paying
agent appointed by the Company) as set forth in the Indenture.

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

          If cash sufficient to pay the purchase price of all Notes or portions
thereof to be purchased as of the Repurchase Date is deposited with the Trustee
(or other paying agent appointed by the Company), on the Business Day following
the Repurchase Date, interest will cease to accrue on such Notes (or portions
thereof) immediately after such Repurchase Date, and the holder thereof shall
have no other rights as such other than the right to receive the purchase price
upon surrender of such Note.

          Subject to the occurrence of certain events and in compliance with the
provisions of the Indenture, the holder hereof has the right, at its option, to
convert each $1,000 principal amount of the Notes into 15.6863 shares of the
Company's Common Stock, subject to adjustment as provided in the Indenture. A
Note in respect of which a holder is exercising its right to require redemption
upon a Designated Event or repurchase on a Repurchase Date may be

                                       A-8
<Page>

converted only if such holder withdraws its election to exercise either such
right in accordance with the terms of the Indenture. The Conversion Rate for the
Notes on any Conversion Date shall be determined as set forth in the Indenture.
The Company shall deliver cash or a check in lieu of any fractional share of
Common Stock.

          The Company shall deliver to the holder through the conversion agent,
no later than the third Business Day following the Conversion Date, a
certificate for the number of whole shares of Common Stock issuable upon the
conversion and, if applicable, cash in lieu of any fractional shares.

          A holder may convert a portion of a Note if the principal amount of
such portion is $1,000 or an integral multiple of $1,000. No payment or
adjustment shall be made for dividends on the Common Stock except as provided in
the Indenture. On conversion of a Note, except for conversion during the period
from the close of business on any record date immediately preceding any interest
payment date to the close of business on the Business Day immediately preceding
such interest payment date, in which case the holder on such record date shall
receive the interest payable on such interest payment date, that portion of
accrued and unpaid interest on the converted Note attributable to the period
from the most recent interest payment date (or, if no interest payment date has
occurred, from the date of original issuance of the Notes) through the
Conversion Date shall not be cancelled, extinguished or forfeited, but rather
shall be deemed to be paid in full to the holder thereof through delivery of the
Common Stock (together with the cash payment, if any, in lieu of fractional
shares), or cash in lieu thereof, in exchange for the Note being converted
pursuant to the provisions hereof.

          Notes or portions thereof surrendered for conversion during the period
from the close of business on any record date immediately preceding any interest
payment date to the close of business on the Business Day immediately preceding
such interest payment date shall be accompanied by payment to the Company or its
order, in immediately available funds or other funds acceptable to the Company,
of an amount equal to the interest payable on such interest payment date with
respect to the principal amount of Notes or portions thereof being surrendered
for conversion; PROVIDED that no such payment need be made if (1) the Company
has specified a Redemption Date that occurs during the period from the close of
business on a record date to the close of business on the Business Day
immediately preceding the interest payment date to which such record date
relates, (2) the Company has specified a Designated Event Redemption Date during
such period or (3) only to the extent of overdue interest, any overdue interest
exists on the Conversion Date with respect to the Notes converted.

          No fractional shares will be issued upon conversion; in lieu thereof,
an amount will be paid in cash based upon the current market price of the Common
Stock as provided in Section 14.03 of the Indenture.

          To convert a Note, a holder must (a) complete and manually sign the
conversion notice set forth below or a facsimile thereof and deliver such notice
to a conversion agent, (b) surrender the Note to the conversion agent, (c)
furnish appropriate endorsements and transfer documents (including any
certification that may be required under applicable law) if required by the
conversion agent, (d) pay any transfer or similar tax, if required and (e) if
required pay funds equal to the interest payable on the next interest payment
date.

                                       A-9
<Page>

          The Conversion Rate will be adjusted as set forth in Article 14 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 redemption date, 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 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 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 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,
