                                      -10-

to the related payment date for such defaulted interest. At least fifteen (15)
days before the special record date, the Company (or, upon the written request
of the Company, the Trustee in the name and at the expense of the Company) shall
mail or cause to be mailed to holders a notice that states the special record
date, the related payment date and the amount of such interest to be paid.

        Section 2.4 Execution of Notes

        The Notes shall be signed in the name and on behalf of the Company by
the facsimile signature of its President, its Chief Executive Officer, or any of
its Vice Presidents, and attested by the facsimile signature of its Chief
Financial Officer, Treasurer or its Assistant Treasurer, or Secretary or any of
its Assistant Secretaries (which may be printed, engraved or otherwise
reproduced thereon, by facsimile or otherwise). Only such Notes as shall bear
thereon a certificate of authentication substantially in the form set forth on
the form of Note attached as Exhibit A hereto, manually executed by the Trustee
(or an authenticating agent appointed by the Trustee as provided by Section
17.11), shall be entitled to the benefits of this Indenture or be valid or
obligatory for any purpose. Such certificate by the Trustee (or such
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 thereof is entitled to the benefits of
this Indenture.

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

        Section 2.5 Exchange and Registration of Transfer of Notes; Restrictions
on Transfer

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

               (b) Transfer and Exchange of Global Notes. A Global Note may not
        be transferred as a whole except by the Depositary to a nominee of the
        Depositary, by a nominee of the Depositary to the Depositary or to
        another nominee of the Depositary, or by the Depositary or any such
        nominee to a successor Depositary or a nominee of such

                                      -11-
<PAGE>

        successor Depositary. All Global Notes will be exchanged by the Company
        for Definitive Notes if (i) the Company delivers to the Trustee notice
        from the Depositary that it is unwilling or unable to continue to act as
        Depositary or that it is no longer a clearing agency registered under
        the Exchange Act and, in either case, a successor Depositary is not
        appointed by the Company within 120 days after the date of such notice
        from the Depositary or (ii) the Company in its sole discretion
        determines that the Global Notes (in whole but not in part) should be
        exchanged for Definitive Notes and delivers a written notice to such
        effect to the Trustee. Upon the occurrence of either of the preceding
        events in (i) or (ii) above, Definitive Notes shall be issued in such
        names as the Depositary shall instruct the Trustee. Global Notes also
        may be exchanged or replaced, in whole or in part, as provided in
        Sections 2.6 and 2.7. Every Note authenticated and delivered in exchange
        for, or in lieu of, a Global Note or any portion thereof, pursuant to
        this Section 2.5(b) or Section 2.6 or 2.7, shall be authenticated and
        delivered in the form of, and shall be, a Global Note. A Global Note may
        not be exchanged for another Note other than as provided in this Section
        2.5(b), however, beneficial interests in a Global Note may be
        transferred and exchanged as provided in Section 2.5(c) or (d).

               (c) Transfer and Exchange of Beneficial Interests in the Global
        Notes. The transfer and exchange of beneficial interests in the Global
        Notes shall be effected through the Depositary, in accordance with the
        provisions of this Indenture and the Applicable Procedures. Beneficial
        interests in the Restricted Global Notes shall be subject to
        restrictions on transfer comparable to those set forth herein to the
        extent required by the Securities Act. Transfers of beneficial interests
        in the Global Notes also shall require compliance with either
        subparagraph (i) or (ii) below, as applicable, as well as one or more of
        the other following subparagraphs, as applicable:

                      (i) Transfer of Beneficial Interests in the Same Global
               Note. Beneficial interests in any Restricted Global Note may be
               transferred to Persons who take delivery thereof in the form of a
               beneficial interest in the same Restricted Global Note in
               accordance with the transfer restrictions set forth in the
               Private Placement Legend. Beneficial interests in any
               Unrestricted Global Note may be transferred to Persons who take
               delivery thereof in the form of a beneficial interest in an
               Unrestricted Global Note. No written orders or instructions shall
               be required to be delivered to the Registrar to effect the
               transfers described in this Section 2.5(c)(i).

                      (ii) All Other Transfers and Exchanges of Beneficial
               Interests in Global Notes. In connection with all transfers and
               exchanges of beneficial interests that are not subject to Section
               2.5(c)(i) above, the transferor of such beneficial interest must
               deliver to the Registrar either (A) (1) a written order from a
               Participant or an Indirect Participant given to the Depositary in
               accordance with the Applicable Procedures directing the
               Depositary to credit or cause to be credited a beneficial
               interest in another Global Note in an amount equal to the
               beneficial interest to be transferred or exchanged and (2)
               instructions given in accordance with the Applicable Procedures
               containing information regarding the Participant account to be
               credited with such increase or (B)(1) a written order

                                      -12-
<PAGE>

               from a Participant or an Indirect Participant given to the
               Depositary in accordance with the Applicable Procedures directing
               the Depositary to cause to be issued a Definitive Note in an
               amount equal to the beneficial interest to be transferred or
               exchanged and (2) instructions given by the Depositary to the
               Note registrar containing information regarding the Person in
               whose name such Definitive Note shall be registered to effect the
               transfer or exchange referred to in (1) above. Upon satisfaction
               of all of the requirements for transfer or exchange of beneficial
               interests in Global Notes contained in this Indenture and the
               Notes or otherwise applicable under the Securities Act, the
               Trustee shall adjust the principal amount of the relevant Global
               Note(s) pursuant to Section 2.5(l).

                      (iii) Transfer of Beneficial Interests to Another
               Restricted Global Note. A beneficial interest in any Restricted
               Global Note may be transferred to a Person who takes delivery
               thereof in the form of a beneficial interest in another
               Restricted Global Note if the transfer complies with the
               requirements of Section 2.5(c)(ii) above and the Note registrar
               receives the following:

                             (A) if the transferee will take delivery in the
                      form of a beneficial interest in the 144A Global Note,
                      then the transferor must deliver a certificate in the form
                      of Exhibit B hereto, including the certifications in item
                      (1) thereof; and

                             (B) if the transferee will take delivery in the

                      the transferor must deliver a certificate in the form of
                      Exhibit B hereto, including the certifications and
                      certificates and Opinion of Counsel required by item (2)
                      thereof, if applicable.

                      (iv) Transfer of Beneficial Interests in a Restricted
               Global Note for Beneficial Interests in the Unrestricted Global
               Note. A beneficial interest in any Restricted Global Note may be
               transferred to a Person who takes delivery thereof in the form of
               a beneficial interest in an Unrestricted Global Note if the
               transfer complies with the requirements of Section 2.5(c)(ii)
               above and

                             (A) such transfer is effected pursuant to a
                      registration statement filed in accordance with the
                      Registration Rights Agreement; or

                             (B) the Note registrar receives the following:

                                    (1) if the Holder of such beneficial
                             interest in a Restricted Global Note proposes to
                             exchange such beneficial interest for a beneficial
                             interest in an Unrestricted Global Note, a
                             certificate from such holder in the form of Exhibit
                             C hereto, including the certifications in item
                             (1)(a) thereof; or

                                    (2) if the Holder of such beneficial
                             interest in a Restricted Global Notes proposes to
                             transfer such beneficial

                             interest to a Person who shall take delivery
                             thereof in the form of a beneficial interest in the
                             Unrestricted Global Note, a certificate from such
                             holder in the form of Exhibit B hereto, including
                             the certifications in item (3) thereof;

                      and, in each such case set forth in this subparagraph (B),
                      if the Note registrar so requests or if the Applicable
                      Procedures so require, an Opinion of Counsel in form
                      reasonably acceptable to the Note registrar to the effect
                      that such exchange or transfer is in compliance with the
                      Securities Act and that the restrictions on transfer
                      contained herein and in the Private Placement Legend are
                      no longer required in order to maintain compliance with
                      the Securities Act.

                      If any such transfer is effected pursuant to subparagraph
               (B) above at a time when an Unrestricted Global Note has not yet
               been issued, the Company shall issue and, upon receipt of an

               shall authenticate one or more Unrestricted Global Notes in an
               aggregate principal amount equal to the aggregate principal
               amount of beneficial interests transferred pursuant to
               subparagraph (B) above.

                      Beneficial interests in an Unrestricted Global Note cannot
               be exchanged for, or transferred to Persons who take delivery
               thereof in the form of, a beneficial interest in a Restricted
               Global Note.

                      contained herein and in the Private Placement Legend are
                      no longer required in order to maintain compliance with
                      the Securities Act.

                      (iii) Unrestricted Definitive Notes to Unrestricted
               Definitive Notes. A Holder of Unrestricted Definitive Notes may
               transfer such Notes to a Person who takes delivery thereof in the
               form of an Unrestricted Definitive Note. Upon receipt of a
               request to register such a transfer, the Note registrar shall
               register the Unrestricted Definitive Notes pursuant to the
               instructions from the Holder thereof.

               (g) General Provisions Relating to Transfers and Exchanges.

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

               No service charge shall be charged to the Noteholder for any
        exchange or registration of transfer of Notes, but the Company may
        require payment of a sum sufficient to cover any tax, assessments or
        other governmental charges that may be imposed in connection therewith.

               None of the Company, the Trustee, the Note registrar or any
        co-registrar shall be required to exchange or register a transfer of (a)
        any Notes for a period of fifteen (15) days next preceding the mailing
        of the notice of redemption or (b) any Notes called for redemption or,
        if a portion of any Note is selected or called for redemption, such
        portion thereof selected or called for redemption or (c) any Notes
        surrendered for conversion or, if a portion of any Note is surrendered
        for conversion, such portion thereof surrendered for conversion or (d)
        any Notes, or a portion of any Note, surrendered for repurchase (and not
        withdrawn) in connection with a Repurchase Event.

               All Notes issued upon any transfer or exchange of Notes in
        accordance with this Indenture 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.

               Prior to due presentment for the registration of a transfer of
        any Note, the Trustee, any agent and the Company may deem and treat the
        Person in whose name any Note is registered as the absolute owner of
        such Note for the purpose of receiving payment of principal of and
        interest on such Notes and for all other purposes, and none of the
        Trustee, any agent or the Company shall be affected by notice to the
        contrary.

               The Trustee shall authenticate Global Notes and Definitive Notes
        in accordance with the provisions of Section 2.1.

               on transfer set forth in this Section 2.5(h)(i) (including the
               legend set forth below), unless such restrictions on transfer
               shall be waived by written consent of the Company, and the holder
               of each such Restricted Security, by such holder's acceptance
               thereof, agrees to be bound by all such restrictions on transfer.
               As used in Sections 2.5(h)(i) and 2.5(h)(ii), the term "transfer"

               until two (2) years after the original issuance date of any Note,
               any certificate evidencing such Note (and all securities issued
               in exchange therefor or substitution thereof, other than Common
               Stock, if any, issued upon conversion thereof which shall bear
               the legend set forth in Section 2.5(h)(ii), if applicable) shall

               Note has been transferred 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
               the Note has been transferred pursuant to the exemption from
               registration provided by Rule 144 under the Securities Act, or
               unless otherwise agreed by the Company in writing, with notice
               thereof to the Trustee):

               A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY THE
               SECURITIES.

                      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 may, upon surrender of
               such Note for exchange to the Note registrar in accordance with
               the provisions of this Section 2.5, be exchanged for a new Note
               or Notes, of like tenor and aggregate principal amount, which
               shall not bear the restrictive legend required by this Section
               2.5(h)(i).

                      (ii) Private Placement Legend on Stock Certificate. Until
               two (2) years after the original issuance date of any Note, any
               stock certificate representing Common Stock issued upon
               conversion of such Note shall bear a legend in substantially the
               following form (unless such Common Stock has been transferred
               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 the Notes from which
               such Common Stock was converted were transferred pursuant to a
               registration statement that has been declared effective under the
               Securities Act and which was effective at the time of such
               transfer, or the Common Stock has been transferred pursuant to an
               exemption from registration provided by Rule 144 under the
               Securities Act, or unless otherwise agreed by the Company in
               writing with written notice thereof to the Trustee and any
               transfer agent for the Common Stock):

               THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
               REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
               "SECURITIES ACT") OR APPLICABLE STATE SECURITIES LAWS. THE
               SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR
               ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
               FOR THE SECURITIES UNDER THE SECURITIES ACT OR APPLICABLE STATE
               SECURITIES LAWS OR AN EXEMPTION THEREFROM. THE SECURITIES MAY BE
               PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER
               LOAN SECURED BY THE SECURITIES.

                      The Company may, but is not obligated to, instruct the
               transfer agent for the Company's Common Stock to place the
               following legend on any certificate evidencing shares of Common
               Stock held by or transferred to an "affiliate" (as defined in
               Rule 501(b) of Regulation D under the Securities Act) of the
               Company:

               PERSON WHO MAY BE DEEMED TO BE AN AFFILIATE OF THE

               ISSUER FOR PURPOSES OF RULE 144 PROMULGATED UNDER THE SECURITIES
               ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND MAY BE SOLD
               ONLY IN COMPLIANCE WITH RULE 144, PURSUANT TO AN EFFECTIVE
               REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO A
               VALID EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT.

                      Any such Common Stock as to which such restrictions on
               transfer shall have expired in accordance with their terms 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 aggregate number of shares
               of Common Stock, which shall not bear the restrictive legend
               required by this Section 2.5(h)(ii).

                      (iii) Global Note Legend. Each Global Note shall bear a
               legend in substantially the following form:

               THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE
               INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE
               BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE
               TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE
               MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO
               SECTION 2.6 OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE
               EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.5(b) OF
               THE INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE
               TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.8 OF THE INDENTURE
               AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR
               DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.

               (i) Resale of Notes Purchased by the Company or an Affiliate. Any
        Note or Common Stock issued upon the conversion or exchange of a Note
        that, prior to the expiration of the holding period applicable to sales
        thereof under Rule 144(k) under the Securities Act (or any successor
        rule), 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 that
        results in such Notes or Common Stock, as the case may be, no longer
        being "restricted securities" (as defined under Rule 144).

               (j) Changes in Law. Notwithstanding any provision of Section 2.5
        to the contrary, in the event Rule 144(k) as promulgated under the
        Securities Act (or any successor rule) is amended to change the two-year
        period under Rule 144(k) (or the corresponding period under any
        successor rule), from and after receipt by the Trustee of

                                      -23-
<PAGE>

        the Officer's Certificate and Opinion of Counsel provided for in this
        Section 2.5(j), (i) each reference in Section 2.5(h)(i) to "two (2)
        years" shall be deemed for all purposes hereof to be references to such
        changed period, (ii) each reference in Section 2.5(h)(ii) to "two (2)
        years" shall be deemed for all purposes hereof to be references to such
        changed period and (iii) all corresponding references in the Notes shall
        be deemed for all purposes hereof to be references to such changed
        period, provided that such changes shall not become effective if they
        are otherwise prohibited by, or would otherwise cause a violation of,
        the then-applicable federal securities laws. As soon as practicable
        after the Company has knowledge of the effectiveness of any such
        amendment to change the two-year period under Rule 144(k) (or the
        corresponding period under any successor rule), unless such changes
        would otherwise be prohibited by, or would otherwise cause a violation
        of, the then-applicable securities law, the Company shall provide to the
        Trustee an Officer's Certificate and Opinion of Counsel informing the
        Trustee of the effectiveness of such amendment and the effectiveness of
        the foregoing changes to Sections 2.5(h)(i) and 2.5(h)(ii) and the
        Notes. The provisions of this Section 2.5(j) will not be effective until
        such time as the Opinion of Counsel and Officer's Certificate have been
        received by the Trustee hereunder. This Section 2.5(j) shall apply to
        successive amendments to Rule 144(k) (or any successor rule) changing
        the holding period thereunder.

               (k) Limitation on Trustee's Duties. The Trustee shall have no
        obligation or duty to monitor, determine or inquire as to compliance
        with any restrictions on transfer imposed under this Indenture or under
        applicable law with respect to any transfer of any interest in any Note
        other than to require delivery of such certificates and other
        documentation or evidence as are expressly required by, and to do so if
        and when expressly required by the terms of, this Indenture, and to
        examine the same to determine substantial compliance as to form with the
        express requirements hereof.

               (l) Cancellation and/or Adjustment of Global Notes. At such time
        as all beneficial interests in a particular Global Note have been
        exchanged for Definitive Notes or a particular Global Note has been
        redeemed, repurchased or canceled in whole and not in part, each such
        Global Note shall be returned to or retained and canceled by the Trustee
        in accordance with Section 2.8. At any time prior to such cancellation,
        if any beneficial interest in a Global Note is exchanged for or
        transferred to a Person who will take delivery thereof in the form of a
        beneficial interest in another Global Note or for Definitive Notes, the
        principal amount of Notes represented by such Global Note shall be
        reduced accordingly and an endorsement shall be made on such Global Note
        by the Trustee or by the Depositary at the direction of the Trustee to
        reflect such reduction; and if the beneficial interest is being
        exchanged for or transferred to a Person who will take delivery thereof
        in the form of a beneficial interest in another Global Note, such other
        Global Note shall be increased accordingly and an endorsement shall be
        made on such Global Note by the Trustee or by the Depositary at the
        direction of the Trustee to reflect such increase.

        Section 2.6   Mutilated, Destroyed, Lost or Stolen Notes

        In case any Note shall become mutilated or be destroyed, lost or stolen,
the Company in its discretion may execute, and upon its request the Trustee or
an authenticating agent appointed by the Trustee shall authenticate and deliver,
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 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 reasonable satisfaction of the
destruction, loss or theft of such Note and of the ownership thereof.

        The Trustee or such authenticating agent may authenticate any such
substituted Note and deliver the same upon the receipt of such security or
indemnity as the Trustee, the Company and, if applicable, such authenticating
agent may reasonably require. Upon the issuance of any substituted Note, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses connected therewith. Once any substitute Note has been issued pursuant
to this Section 2.6, the original Note being replaced by such substitute Note
shall automatically be deemed cancelled. In case any Note which has matured or
is about to mature or has been called for redemption or is about 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 will
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 case of
destruction, loss or theft, evidence reasonably satisfactory to the Company, the
Trustee and, if applicable, any paying agent or conversion agent of the
destruction, loss or theft of such Note and of the ownership thereof.

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

        Section 2.7   Temporary Notes

        Pending the preparation of definitive Notes, the Company may execute and
the Trustee or an authenticating agent appointed by the Trustee shall, upon
written request of the Company, authenticate and deliver temporary Notes
(printed or lithographed). Temporary Notes shall be issuable in any authorized
denomination, and substantially in the form of the Global Notes or the
Definitive Notes, as the case may be, 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 Definitive Notes or Global Notes. Without unreasonable delay the Company
will execute and deliver to the Trustee or such authenticating agent Definitive
Notes and Global Notes and thereupon any or all temporary Notes may be
surrendered in exchange for the applicable replacement Note, at each office or
agency maintained by the Company pursuant to Section 5.2 and the Trustee or such
authenticating agent shall authenticate and deliver in exchange for such
temporary Notes an equal aggregate principal amount of Definitive Notes or
Global Notes, as the case may be. 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 Definitive Notes or
Global Notes, as the case may be, authenticated and delivered hereunder.

        Section 2.8   Cancellation of Notes Paid, Etc.

        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. Upon written instructions of the Company, the
Trustee shall dispose of canceled Notes in accordance with its customary
procedures. If the Company shall acquire any of the Notes, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Notes unless and until the same are delivered to the Trustee
for cancellation.

        Section 2.9   CUSIP Numbers

        The Company in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the 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.

        From and after June 21, 2005, the Company may, at its option, redeem all
or any part of the Notes, upon notice as set forth in Section 3.2, and the
Company shall pay each holder of Notes redeemed the appropriate redemption price

        Section 3.2 Notice of 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 3.1, it shall fix
a date for redemption, and it, or at its request (which must be received by the
Trustee at least ten (10) Business Days prior to the date the Trustee is
requested to give notice as described below unless a shorter period is agreed to
by the Trustee), 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 at least thirty
(30) and not more than ninety (90) days prior to the date fixed for redemption
to the holders of Notes so to be redeemed as a whole or in part at their last
addresses as the same appear on the Note register (provided that if the Company
shall give such notice, it shall also give such notice, and notice of the
aggregate amount of Notes to be redeemed, 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.

        Each such notice of redemption shall specify the aggregate principal
amount of Notes to be redeemed, the "CUSIP" number or numbers of such Notes, if
any, the date fixed for redemption, 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, but
excluding, the date fixed for redemption will be paid as specified in said
notice, and that on and after said date interest thereon or on the portion
thereof to be redeemed will cease to accrue. Such notice shall also state the
current Conversion Price and the date on which the right to convert such Notes
or portions thereof into Common Stock will expire. If fewer than all the Notes
are to be redeemed, the notice of redemption shall identify the Notes to be

                                      -27-
<PAGE>

redeemed. In case any Note is to be redeemed in part only, the notice of
redemption shall state the portion of the principal amount thereof to be
redeemed and shall state that on and after the date fixed for redemption, upon
surrender of such Note, a new Note or Notes in principal amount equal to the
unredeemed portion thereof will be issued.

        On or prior to the redemption date specified in the notice of redemption
given as provided in this Section, the Company will deposit with the Trustee or
with one or more paying agents (or, if the Company is acting as its own paying
agent, set aside, segregate and hold in trust as provided in Section 5.4) an
amount of money sufficient to redeem on the redemption date all the Notes (or
portions thereof) so called for redemption (other than those theretofore
surrendered for conversion into Common Stock) at the appropriate redemption
price, together with accrued interest to, but excluding, the date fixed for
redemption; provided that if such payment is made on the redemption date it must
be received by the Trustee or paying agent, as the case may be, by 10:00 a.m.
New York City time, on such date. If any Note called for redemption is converted
pursuant hereto, 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 request, or, if then held by the Company shall be
discharged from such trust.

        If fewer than all the Notes are to be redeemed, the Company will give
the Trustee written notice in the form of an Officer's 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 fewer than all the Notes are to be redeemed,
the Trustee shall select the Notes or portions thereof to be redeemed (in
principal amounts of $1,000 or integral multiples thereof), on a pro rata basis.
If any Note selected for partial redemption is converted in part after such
selection, the converted portion of such Note shall be deemed (so far as is
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 converted as a whole
or in part before the mailing of the notice of redemption.

        Upon any redemption of less than all Notes, the Company and the Trustee
may (but need not) 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 not outstanding any Note
authenticated and delivered during such period in exchange for the unconverted
portion of any Note converted in part during such period.

        Section 3.3 Payment of Notes Called for Redemption

        If notice of redemption has been given as above provided, the Notes or
portion of Notes with respect to which such notice has been given shall, unless
converted into Common Stock pursuant to the terms hereof, become due and payable
on the date and at the place or places stated in such notice at the applicable
redemption price, and interest accrued to, but excluding, the date fixed for
redemption, and on and after said date (unless the Company shall default in the
payment of such Notes at the redemption price and interest accrued to, but
excluding, said date) interest on the Notes or portion of Notes so called for
redemption shall cease to accrue and such Notes shall cease after the close of
business on the Business Day next preceding the date fixed

                                      -28-
<PAGE>

for redemption to be convertible into Common Stock and, except as provided in
Sections 8.5 and 13.4, to be entitled to any benefit or security under this
Indenture, and the holders thereof shall have no right in respect of such Notes
except the right to receive the redemption price thereof and unpaid interest to,
but excluding, the date fixed for redemption. On presentation and surrender of
such Notes at a place of payment specified in said notice, the said Notes or the
specified portions thereof to be redeemed shall be paid and redeemed by the
Company at the applicable redemption price and interest accrued thereon to, but
excluding, the date fixed for redemption; provided that, if the applicable
redemption date is an interest payment date, the semi-annual payment of interest
becoming due on such date shall be payable to the holders of such Notes
registered as such on the relevant record date subject to the terms and
provisions of Section 2.3.

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

        Notwithstanding the foregoing, the Trustee shall not redeem any Notes or
mail any notice of optional redemption during the continuance of a default in
payment of interest or premium on the Notes or of any Event of Default of which,
in the case of any Event of Default other than under Section 7.1(a), (b) or (d),
a Responsible Officer of the Trustee has actual knowledge. If any Note called
for redemption shall not be so paid upon surrender thereof for redemption, the
principal and premium, if any, shall, until paid or duly provided for, bear
interest from the date fixed for redemption at the rate borne by the Note and
such Note shall remain convertible into Common Stock until the principal and
premium, if any, shall have been paid or duly provided for.

        Section 3.4 Conversion Arrangement on Call for Redemption

        In connection with any redemption of Notes, the Company may arrange for
the purchase and conversion of any Notes not converted prior to the expiration
of such conversion right by an agreement with one or more investment bankers or
other purchasers to purchase such Notes by paying to the Trustee in trust for
the Noteholders, on or before the date fixed for redemption, an amount not less
than the applicable redemption price and interest accrued to the date fixed for
redemption, of such Notes. Notwithstanding anything to the contrary contained in
this Article III, the obligation of the Company to pay the redemption price of
such Notes and 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 to such Noteholders. If such an agreement
is entered into, a copy of which, certified as true and correct by the Secretary
or Assistant Secretary of the Company 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 XV) 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 deemed to have been extended through such time), subject to
payment of the above amount as

                                      -29-

aforesaid. At the written 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, and the Company agrees to indemnify
the Trustee from, and hold it harmless against, any loss, liability or expense
arising out of or in connection with any such arrangement for the purchase and
conversion of any Notes between the Company and such purchasers, including the
costs and expenses incurred by the Trustee in the defense of any claim or
liability arising out of or in connection with the exercise or performance of
any of its powers, duties, responsibilities or obligations under this Indenture.

                                   ARTICLE IV

                                  SUBORDINATION

        Section 4.1   Subordination to Senior Indebtedness

        The Company covenants and agrees, and each holder of a Note, by his or
her acceptance thereof, likewise covenants and agrees, that all Notes shall be
issued subject to the provisions of this Article IV and to the extent and in the
manner hereinafter set forth in this Article IV, the indebtedness represented by
the Notes and the payment of the principal amount, Conversion Price, and
interest thereon, liquidated damages or any other amounts in respect of each and
all of the Notes are hereby expressly made subordinate and junior and subject in
right of payment to the prior payment in full of all Senior Indebtedness of the
Company now outstanding or hereinafter incurred. "Senior Indebtedness" means the
principal of, and premium, if any, and interest on, fees, costs and expenses in
connection with and other amounts due on (i) all indebtedness of the Company for
monies borrowed, including, without limitation, commercial paper and accounts
receivable sold or assigned by the Company, (ii) all obligations of the Company
evidenced by any notes, debentures, bonds or other instruments issued to banks,
trust companies, insurance companies, other financial institutions and other
entities that in the ordinary course of business make loans, (iii) all
obligations of the Company under any interest or currency swap agreements,
hedging agreements, cap, floor and collar agreements, spot and forward contracts
and other similar agreements, (iv) obligations in respect of letters of credit,
bank guarantees and bankers acceptances, (v) obligations of the Company as
lessee under leases of personal property (whether or not required to be
capitalized under GAAP), (vi) obligations secured by a mortgage, pledge,
security interest, lien or encumbrance affecting title to any of the Company's
assets, whether or not the Company is directly liable or has guaranteed such
obligations, (vii) obligations consisting of the balance of the deferred or
unpaid purchase price of assets, (viii) principal of, and interest on any
indebtedness or obligations of others of the kinds described in (i) through
(viii) above assumed or guaranteed in any manner by the Company, and (ix)
deferrals, renewals, extensions and refundings of any such indebtedness or
obligations described in (i) through (viii) above, in each case unless the
instrument creating or evidencing the same or pursuant to which the same is
outstanding expressly provides that the same is not senior in right of payment
to the Notes. Senior Indebtedness includes, with respect to the

                                      -30-
<PAGE>

foregoing, interest accruing on or after the filing of any petition in
bankruptcy or for reorganization relating to the Company, whether or not
post-filing interest is allowed in such proceeding. Notwithstanding the
foregoing, "Senior Indebtedness" with respect to any Note shall not include (a)
indebtedness of the Company evidenced by the other Notes, which shall rank
equally and ratably with such Note, (b) any obligation of the Company to any
Subsidiary or Affiliate of the Company, (c) any liability for Federal, state,
local or other taxes owed or owing by the Company, (d) any accounts payable or
other liability to trade creditors arising in the ordinary course of business
(including guarantees thereof or instruments evidencing such liabilities), (e)
any indebtedness or obligation of the Company (and any accrued and unpaid
interest in respect thereof) that by its terms is subordinate or junior in right
of payment to any other indebtedness or obligation of the Company, or (f) any
obligation with respect to any shares, interest, rights to purchase, warrants,
options, participations or other equivalents of, or interests in, the equity of
the Company or any Subsidiary or Affiliate, including any preferred stock or
other preferred equity.

        Section 4.2 No Payment if Default in Senior Indebtedness

        No payment on account of principal of or interest on the Notes shall be
made, and no Notes shall be redeemed or purchased directly or indirectly by the
Company (or any of its Subsidiaries), if at the time of such payment or purchase
or immediately after giving effect thereto, (i) a default in the payment of
principal, premium, if any, interest, rent or other obligations in respect of
any Senior Indebtedness occurs and is continuing (or, in the case of Senior
Indebtedness for which there is a period of grace, in the event of such a
default that continues beyond the period of grace, if any, specified in the
instrument or lease evidencing such Senior Indebtedness) (a "Payment Default"),
unless and until such Payment Default shall have been cured or waived or shall
have ceased to exist or (ii) the Company shall have received notice (a "Payment
Blockage Notice") from the holder or holders of Designated Senior Debt that
there exists under such Designated Senior Debt a default, which shall not have
been cured or waived, permitting the holder or holders thereof to declare such
Designated Senior Debt due and payable, but only for the period (the "Payment
Blockage Period") commencing on the date of receipt of the Payment Blockage
Notice and ending on the earlier of (a) the date such default shall have been
cured or waived, or (b) the 180th day immediately following the Company's
receipt of such Payment Blockage Notice. The Company shall resume payments on
and distributions in respect of the Notes, including any past scheduled payments
of the principal of (and premium, if any) and interest on such Notes to which
the Holders of the Notes would have been entitled but for the provisions of this
Section 4.2 in the case of a Payment Default, on the date upon which such
Payment Default is cured or waived or ceases to exist. In addition,
notwithstanding clauses (i) and (ii), unless the holders of Designated Senior
Debt shall have accelerated the maturity of such Designated Senior Debt, the
Company shall resume payments on the Note after the end of each Payment Blockage
Period. Not more than one Payment Blockage Notice may be given in any
consecutive 360-day period, irrespective of the number of defaults with respect
to Designated Senior Debt during such period.

        Section 4.3 Payment upon Dissolution, Etc.

               (a) In the event of any bankruptcy, insolvency, reorganization,
        receivership, composition, assignment for benefit of creditors or other
        similar proceeding initiated by or against the Company or any
        dissolution or winding up or total or partial liquidation or
        reorganization of the Company (being hereinafter referred to as a
        "Proceeding"), each holder of a Note, by his or her acceptance thereof,
        agrees that such holder shall, upon request of a holder of Senior
        Indebtedness, and at such holder's own expense take all reasonable
        actions (including but not limited to the execution and filing of
        documents and the giving of testimony in any Proceeding, whether or not
        such testimony could have been compelled by process) necessary to prove
        the full amount of all their claims in any Proceeding, and the
        Noteholders shall not waive any claim in any Proceeding without the
        written consent of such Holder.

               (b) Upon payment or distribution to creditors in a Proceeding of
        assets of the Company of any kind or character, whether in cash,
        property or securities, all principal and interest due upon any Senior
        Indebtedness shall first be paid in full before any Holders of the Notes
        shall be entitled to receive or, if received, to retain any payment or
        distribution on account of the Notes, and upon any such Proceeding, any
        payment or distribution of assets of the Company of any kind or
        character, whether in cash, property or securities, to which any Holders
        of the Notes would be entitled except for the provisions of this Article
        IV shall be paid by the Company or by any receiver, trustee in
        bankruptcy, liquidating trustee, agent or other Person making such
        payment or distribution, or by any holders of the Notes who shall have
        received such payment or distribution, directly to the holders of the
        Senior Indebtedness (pro rata to each such holder on the basis of the
        respective amounts of such Senior Indebtedness held by such holder) or
        their representatives to the extent necessary to pay all such Senior
        Indebtedness in full after giving effect to any concurrent payment or
        distribution to or for the holders of such Senior Indebtedness, before
        any payment or distribution is made to any holders of the Notes.

        Section 4.4 Payments on Notes

        Subject to Section 4.3, the Company may make payments of the principal
of, and any interest or premium on, the Notes, if at the time of payment, and
immediately after giving effect thereto, (i) there exists no Payment Default or
a Payment Blockage Period and (ii) the Company is permitted to make payments
under Section 4.3.

        Section 4.5 Certain Conversions Deemed Payment

        For the purposes of this Article IV only (a) the issuance and delivery
of junior securities upon conversion of Notes in accordance with Article XV
shall not be deemed to constitute a payment of distribution on account of the
principal of or interest on Notes or on account of the purchase or other
acquisition of Notes, and (b) the payment, issuance or delivery of cash (except
in satisfaction of fractional shares pursuant to Section 15.3), property or
securities (other than

                                      -32-
<PAGE>

junior securities) upon conversion of a Note shall be deemed to constitute
payment on account of the principal of such Note. For the purposes of this
Section 4.5, the term "junior securities" means (i) shares of any stock of any
class of the Company, or (ii) securities of the Company which are subordinated
in right of payment to all Senior Indebtedness which may be outstanding at the
time of issuance or delivery of such securities to substantially the same extent
as, or to a greater extent than, the Notes are so subordinated as provided in
this Article IV. Nothing contained in this Article IV or elsewhere in this
Indenture or in the Notes is intended to or shall impair, as among the Company,
its creditors other than holders of Senior Indebtedness and the holders, the
right, which is absolute and unconditional, of the holder of any Note to convert
such Note in accordance with Article IV.

        Section 4.6 Subrogation

        Subject to payment in full of all Senior Indebtedness, the holders of
the Notes shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of the assets of the Company
made on such Senior Indebtedness until all principal and interest on the Notes
shall be paid in full; and for purposes of such subrogation, no payments or
distributions to the holders of Senior Indebtedness of any cash, property or
securities to which any holders of the Notes would be entitled except for the
subordination provisions of this Article IV shall, as between the holders of the
Notes and the Company and/or its creditors other than the holders of the Senior
Indebtedness, be deemed to be a payment on account of the Senior Indebtedness.

        Section 4.7 Rights of Holders Unimpaired

        The provisions of this Article IV are and are intended solely for the
purposes of defining the relative rights of the holders of the Notes and the
holders of Senior Indebtedness and nothing in this Article IV shall impair, as
between the Company and any holders of the Notes, the obligation of the Company,
which is unconditional and absolute, to pay to the holders of the Notes the
principal thereof (and premium, if any) and interest thereon, in accordance with
the terms of the Notes.

        Section 4.8 Holders of Senior Indebtedness

        These provisions regarding subordination will constitute a continuing
offer to all Persons who, in reliance upon such provisions, become holders of,
or continue to hold, Senior Indebtedness; such provisions are made for the
benefit of the holders of Senior Indebtedness, and such holders are hereby made
obligees under such provisions to the same extent as if they were named therein,
and they or any of them may proceed to enforce such subordination. The holders
of Senior Indebtedness may, at any time and from time to time, without the
consent of or notice to any of the Noteholders, without incurring responsibility
to the Noteholders and without impairing or releasing the subordination
provisions of this Article IV, (i) change the manner, terms or place of payment
of, or renew or alter, any Senior Indebtedness, or otherwise amend or supplement
the same, (ii) sell, exchange or release any collateral mortgaged, pledged or
otherwise securing the Senior Indebtedness, (iii) release any Person liable in
any manner for the

                                      -33-
<PAGE>

Senior Indebtedness and (iv) exercise or refrain from exercising any rights
against the Company or any other Person.

        Section 4.9 Trustee Not Fiduciary for Holders of Senior Indebtedness

        The Trustee shall not be deemed to owe any fiduciary duty to the holders
of Senior Indebtedness and shall not be liable to any such holders if the
Trustee shall in good faith mistakenly pay over or distribute to Holders of
Notes or to the Company or to any other person cash, property or securities to
which any holders of Senior Indebtedness shall be entitled by virtue of this
Article IV or otherwise. With respect to the holders of Senior Indebtedness, no
implied covenants or obligations with respect to holders of Senior Indebtedness
shall be read into this Indenture against the Trustee.

        Section 4.10 Rights of Trustee as Holder of Senior Indebtedness;
Preservation of Trustee's Rights

        The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article IV with respect to any Senior Indebtedness
which may at any time be held by it, to the same extent as any other holder of
Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of
any of its rights as such holder.

        Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 8.6.

                                    ARTICLE V

                       PARTICULAR COVENANTS OF THE COMPANY

        Section 5.1 Payment of Principal, Premium and Interest

        The Company covenants and agrees that it will duly and punctually pay or
cause to be paid the principal of and premium, if any, and interest on each of
the Notes at the places, at the respective times and in the manner provided
herein and in the Notes. Liquidated Damages paid pursuant to Section 15.2, if
any, shall be paid within ten (10) Business Days of the date from which such
liquidated damages accrued pursuant to Section 15.2. Liquidated Damages on the
Notes paid pursuant to Section 2(f) of the Registration Rights Agreement, if
any, shall be paid at the times and in the manner provided therein. Each
installment of interest on the Notes due on any semi-annual interest payment
date may be paid by mailing checks for the interest payable to or upon the
written order of the holders of Notes entitled thereto as they shall appear on
the Note register, provided that, with respect to any holder of Notes with an
aggregate principal amount equal to or in excess of $500,000, at the request of
such holder in writing to the Company, interest on such holder's Notes shall be
paid by wire transfer in immediately available funds in accordance with the wire
transfer instructions supplied by such holder from time to time to the Trustee
and paying agent (if different from Trustee) at least two (2) Business Days
prior to the applicable record date.

        Section 5.2 Maintenance of Office or Agency

        The Company will maintain in the Borough of Manhattan, The City of New
York, an office or agency where the Notes may be presented for registration of
transfer or exchange or for presentation for payment or for conversion,
redemption or repurchase and where notices and demands to or upon the Company in
respect of the Notes and this Indenture may be served. The Company will give
prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency not designated or appointed by the Trustee.
If at any time the Company shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office or the office or agency of the Trustee in the Borough of
Manhattan, The City of New York.

        The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided
that no such designation or rescission shall in any manner relieve the Company
of its obligation to maintain an office or agency in the Borough of Manhattan,
The City of New York, for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.

        The Company hereby initially designates the Trustee as paying agent,
Note registrar, Custodian and conversion agent and the Corporate Trust Office
and the office or agency of the Trustee in the Borough of Manhattan, The City of
New York (which initially shall be The Bank of New York, located at 101 Barclay
Street, New York, New York 10286, Attention: Corporate Trust Administration), as
one such office or agency of the Company for each of the aforesaid purposes.

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

        Section 5.3 Appointments to Fill Vacancies in Trustee's Office

that there shall at all times be a Trustee hereunder.

        Section 5.4 Provisions as to Paying Agent

               (a) If the Company shall appoint a paying agent other than the
        Trustee or if the Trustee shall appoint such a paying agent, it will
        cause such paying agent to execute and deliver to the Trustee an
        instrument in which such agent shall agree with the Trustee, subject to
        the provisions of this Section 5.4:

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

                                      -35-
<PAGE>

                      (2) that it will give the Trustee notice of any failure by
               the Company (or by any other Person) to make any payment of the
               principal of and premium, if any, or interest (including
               Liquidated Damages, if any) 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, premium, if any, or interest on the Notes, deposit with the paying
        agent a sum sufficient to pay such principal, premium, if any, 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 must be
        received by the paying agent by 10:00 a.m., New York City time, on such
        date.

               (b) If the Company shall act as its own paying agent, it will, on
        or before each due date of the principal of, premium, if any, or
        interest (including Liquidated Damages, if any) on the Notes, set aside,
        segregate and hold in trust for the benefit of the holders of the Notes
        a sum sufficient to pay such principal, premium, if any, or interest
        (including Liquidated Damages, if any) so becoming due and will notify
        the Trustee of any failure to take such action and of any failure by the
        Company (or any other Person) to make any payment of the principal of,
        premium, if any, or interest (including Liquidated Damages, if any) on
        the Notes when the same shall become due and payable.

               (c) Anything in this Section 5.4 to the contrary notwithstanding,
        the Company may, at any time, for the purpose of obtaining a
        satisfaction and discharge of this Indenture, or for any other reason,
        pay or cause to be paid to the Trustee all sums held in trust by the
        Company or any paying agent hereunder as required by this Section 5.4,
        such sums to be held by the Trustee upon the trusts herein contained and
        upon such payment by the Company or any paying agent to the Trustee, the
        Company or such paying agent shall be released from all further
        liability with respect to such sums.

               (d) Anything in this Section 5.4 to the contrary notwithstanding,
        the agreement to hold sums in trust as provided in this Section 5.4 is

        Section 5.6 Information Requirement

        Within the period prior to the expiration of the holding period
applicable to sales thereof under Rule 144(k) under the Securities Act (or any
successor provision), the Company covenants and agrees that it shall, during any
period in which it is not subject to Section 13 or 15(d) under

                                      -36-

prospective purchaser of Notes or such Common Stock from 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 in
connection with qualification of such sale for exemption from registration under
Rule 144A.

        Section 5.7 Stay, Extension and Usury Laws

        The Company covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law or other law
that would prohibit or forgive the Company from paying all or any portion of the
principal of or interest on the Notes as contemplated herein, wherever enacted,
now or at any time hereafter in force, or which may affect the covenants or the
performance of this Indenture; and the Company (to the extent it may lawfully do
so) hereby expressly waives all benefit or advantage of any such law, and
covenants that it will not, by resort to any such law, hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and

principal executive, principal financial officer or accounting officer of the
Company, stating whether or not to the best of such person's knowledge the
signers know of any default or Event of Default that occurred during such
period. Such Officer's Certificate shall describe in reasonable detail the
default or Event of Default, if any, and its status.

        The Company shall deliver to the Trustee, as soon as possible and in any
event within three (3) Business Days after the Company becomes aware of the
occurrence of any Event of Default or an event which, with notice or the lapse
of time or both, would constitute an Event of Default, an Officer's Certificate
setting forth the details of such Event of Default or default and the action
which the Company proposes to take with respect thereto.

        Section 6.1 Noteholders Lists

        The Company covenants and agrees that it will furnish or cause to be
furnished to the Trustee, semi-annually, not more than fifteen (15) days after
each June 1 and December 1 in each year beginning with December 1, 2002 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 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 so
long as the Trustee is acting as Note registrar.

        Section 6.2 Preservation and Disclosure of Lists

            (a) The Trustee shall preserve, in as current a form as is
reasonably practicable, all information as to the names and addresses of the
holders of Notes contained in the most recent list furnished to it as provided

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.

(as to which the Trustee is entitled to rely exclusively on Officer's
Certificates).

        same, shall have been given to the Company by the Trustee, or to the
        Company and a Responsible Officer of the Trustee by the holders of at

        have been given, by registered or certified mail, to the Company by the
        Trustee or to the Company and the Trustee by the holders of not less
        than 15% in aggregate principal amount of the Notes then outstanding, a
        written notice specifying such default and requiring the Company to

        or seeking the appointment of a trustee, receiver, liquidator, custodian
        or other similar official of it or any substantial part of its property,
        or shall consent to any such relief or to the appointment of or taking
        possession by any such official in an involuntary case or other
        proceeding commenced against it, or shall make a general assignment for
        the benefit of creditors, or shall fail generally to pay its debts as
        they become due; or

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

               (k) any of the representations or warranties made by the Company
        herein or in the Transaction Documents shall be false or misleading in
        any material respect at the time made and such condition (to the extent
        capable of being cured) shall continue uncured for a period of five (5)
        Business Days after there shall have been given, by registered or
        certified mail, to the Company by the Trustee or to the Company and the
        Trustee by the holders of not less than 15% in aggregate principal
        amount of the Notes then outstanding, a written notice specifying such
        default and requiring the Company to cause such default to be cured or
        waived and stating that such notice is a "Notice of Default" hereunder;
        or

               (l) the Company shall fail to duly observe or perform any of the
        covenants on the part of the Company in the Transaction Documents (other
        than the Notes and this Indenture), and such failure shall continue for
        thirty (30) days after there shall have been given, by registered or
        certified mail, to the Company by the Trustee or to the Company and the
        Trustee by the holders of not less than 15% in aggregate principal
        amount of the Notes then outstanding, a written notice specifying such
        default and requiring the Company to cause such default to be cured or
        waived and stating that such notice is a "Notice of Default" hereunder;

then, and in each and every such case (other than an Event of Default specified
in Section 7.1(i) or (j) with respect to the Company), unless the principal of
all of the Notes shall have already

                                      -41-
<PAGE>

become due and payable, either the Trustee or the holders of not less than 15%
in aggregate principal amount of the Notes then outstanding hereunder determined
in accordance with Section 9.4, by notice in writing to the Company (and to the
Trustee if given by Noteholders), may declare the principal of and premium, if
any, on all the Notes and the interest accrued thereon (including Liquidated
Damages to the extent accrued and unpaid) to be due and payable immediately, and
upon any such declaration the same shall become and shall be immediately due and
payable, anything in this Indenture or in the Notes contained to the contrary
notwithstanding. If an Event of Default specified in Section 7.1(i) or (j)
occurs and is continuing with respect to the Company, the principal of all the
Notes and the interest accrued thereon (including Liquidated Damages to the
extent accrued and unpaid) shall be immediately due and payable. In addition to
the foregoing, on the thirty-first (31st) day after the occurrence of an Event
of Default and during the continuance of such Event of Default, the rate of
interest on the Notes shall, to the maximum extent permitted by law, be
increased by five percent (5%) per annum (i.e., from 5.25% to 10.25% per annum).
Any such interest which is not paid when due shall, to the maximum extent
permitted by law, accrue interest until paid at the rate from time to time
applicable to the principal of the Notes. Notwithstanding the foregoing 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 and premium, if
any, on any and all Notes which shall have become due otherwise than by
acceleration (with interest on overdue installments of interest (to the extent
that payment of such interest is enforceable under applicable law) and on such
principal and premium, if any, at the rate borne by the Notes, to the date of
such payment or deposit) and amounts due to the Trustee pursuant to Section 8.6,
and if any and all defaults under this Indenture, other than the nonpayment of
principal of and premium, if any, and accrued interest on Notes which shall have
become due by acceleration, shall have been cured or waived pursuant to Section
7.7, then and in every such case the holders of a majority in aggregate
principal amount of the Notes then outstanding, by written notice to the Company
and to the Trustee, may waive all defaults or Events of Default and rescind and
annul such acceleration 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
the Responsible Officer of the Trustee, within two (2) Business Days of becoming
aware thereof, of any default or Event of Default and shall deliver to the
Trustee a statement specifying such default or Event of Default and the action
the Company has taken, is taking or proposes to take with respect thereto.

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

        Section 7.2 Payments of Notes on Default; Suit Therefor

        The Company covenants that (a) in case default shall be made in the
payment by the Company 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 or premium, if any, on 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 declaration 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 and premium, if any, or interest, or both, as the case may be, with
interest upon the overdue principal and premium, if any, and (to the extent that
payment of such interest is enforceable under applicable law) upon the overdue
installments of interest at the rate borne by the Notes; and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including reasonable compensation to the Trustee, its
agents, attorneys and counsel, and any expenses or liabilities incurred by the
Trustee hereunder other than through its negligence or bad faith. Until such
demand by the Trustee, the Company may pay the principal of and premium, if any,
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, the Trustee, irrespective of whether the principal of the Notes shall
then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand pursuant to the
provisions of this Section 7.2, shall be entitled and empowered, by intervention
in such proceedings or otherwise, to file and prove a claim or claims for the
whole amount of principal, premium, if any, and interest (including Liquidated
Damages, if any) owing and unpaid in respect of the Notes, and, in case of any
judicial proceedings, to file such proofs of claim and other papers or documents
and to take such other actions as it may deem necessary or advisable in order to
have the claims of the Trustee and of the Noteholders allowed in such judicial
proceedings relative to the Company or any other obligor on the Notes, its or
their creditors, or its or their property, and to collect and receive any monies
or other property payable or deliverable on any such claims, and to distribute
the same after the deduction of any amounts due the Trustee under Section 8.6;
and any receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, custodian or similar official is hereby authorized by

                                      -43-
<PAGE>

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 agents and counsel
fees incurred by it up to the date of such distribution. To the extent that such
payment of reasonable compensation, expenses, advances and disbursements out of
the estate in any such proceedings shall be denied for any reason, payment of
the same shall be secured by a lien on, and shall be paid out of, any and all
distributions, dividends, monies, securities and other property which the
holders of the Notes may be entitled to receive in such proceedings, whether in
liquidation or under any plan of reorganization or arrangement or otherwise.

        All rights of action and of asserting claims under this Indenture, or
under any of the Notes, may be enforced by the Trustee without the possession of
any of the Notes, or the production thereof on 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 7.3 Application of Monies Collected by Trustee

        Any monies collected by the Trustee pursuant to this Article VII shall
be applied in the following order, at the date or dates fixed by the Trustee for
the distribution of such monies, upon presentation of the several Notes, and
stamping thereon the payment, if only partially paid, and upon surrender
thereof, if fully paid:

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

               Second: To the holders of Senior Indebtedness to the extent
        required by Article IV;

               Third: 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, such payments to be made ratably to the
        Persons entitled thereto;

               Fourth: In case the principal of the outstanding Notes shall have
        become due, by declaration or otherwise, and be unpaid, to the payment
        of the whole amount then owing and unpaid upon the Notes for principal
        and premium, if any, and interest, with interest on the overdue
        principal and premium, if any, and (to the extent that such interest has
        been collected by the Trustee) upon overdue installments of interest at
        the rate borne

                                      -44-
<PAGE>

        by the Notes; and in case such monies shall be insufficient to pay in
        full the whole amounts so due and unpaid upon the Notes, then to the
        payment of such principal and premium, if any, and interest without
        preference or priority of principal and premium, if any, over interest,
        or of interest over principal and premium, if any, or of any installment
        of interest over any other installment of interest, or of any Note over
        any other Note, ratably to the aggregate of such principal and premium,
        if any, and accrued and unpaid interest; and

               Fifth: To the payment of the remainder, if any, to the Company.

        Section 7.4 Proceedings by Noteholder

        Subject to the last two paragraphs of this Section 7.4, no holder of any
Note shall have any right by virtue of or by availing of 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 15% in
aggregate principal amount of the Notes then outstanding shall have made written
request upon the Trustee to institute such action, suit or proceeding in its own
name as Trustee hereunder and shall have offered to the Trustee such indemnity
as may be reasonably satisfactory to the Trustee against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee for sixty (60)
days after its receipt of such notice, request and offer of indemnity, shall
have neglected or refused to institute any such action, suit or proceeding and
no direction inconsistent with such written request shall have been given to the
Trustee pursuant to Section 7.7; it being understood and intended, and being
expressly covenanted by the taker and holder of every Note with every other
taker and holder and the Trustee, that no one or more holders of Notes shall
have any right in any manner whatever by virtue of or by availing of any
provision of this Indenture to affect, disturb or prejudice the rights of any
other holder of Notes, or to obtain or seek to obtain priority over or
preference to any other such holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all holders of Notes (except as otherwise provided herein).
For the protection and enforcement of this Section 7.4, each and every
Noteholder and the Trustee shall be entitled to such relief as can be given
either at law or in equity.

        Notwithstanding any other provision of this Indenture and any provision
of any Note, the right of any holder of any Note to receive payment of the
principal of and premium, if any, and interest (including Liquidated Damages to
the extent accrued but unpaid) on such Note, on or after the respective due
dates expressed in such Note, 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 his own behalf and for his own benefit, may enforce, and
may institute and maintain any proceeding suitable to enforce, such holder's
rights of conversion as provided herein.

        Section 7.5 Proceedings by Trustee

        If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either by suit in
equity or by action at law or by proceeding in bankruptcy or otherwise, whether
for the specific enforcement of any covenant or agreement contained in this
Indenture or in aid of the exercise of any power granted in this Indenture, or
to enforce any other legal or equitable right vested in the Trustee by this
Indenture or by law.

        Section 7.6 Remedies Cumulative and Continuing

        Except as provided in the last paragraph of Section 2.6, all powers and
remedies given by this Article VII to the Trustee or to the Noteholders shall,
to the extent permitted by law, be deemed cumulative and not exclusive of any
thereof or of any other powers and remedies available to the Trustee or the
holders of the Notes, by judicial proceedings or otherwise, to enforce the
performance or observance of the covenants and agreements contained in this
Indenture, and no delay or omission of the Trustee or of any holder of any of
the Notes to exercise any right or power accruing upon any default or Event of
Default occurring and continuing as aforesaid shall impair any such right or
power, or shall be construed to be a waiver of any such default or any
acquiescence therein; and, subject to the provisions of Section 7.4, every power
and remedy given by this Article VII or by law to the Trustee or to the
Noteholders may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Noteholders.

        Section 7.7 Direction of Proceedings and Waiver of Defaults by Majority
of Noteholders

        The holders of a majority in aggregate principal amount of the Notes at
the time outstanding determined in accordance with Section 9.4 shall have the
right to direct the time, method, and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee; provided, however, that (a) such direction shall not be in conflict
with any rule of law or with this Indenture, and (b) the Trustee may take any
other action deemed proper by the Trustee which is not inconsistent with such
direction. The holders of not less than a majority in aggregate principal amount
of the Notes at the time outstanding determined in accordance with Section 9.4
may on behalf of the holders of all of the Notes waive any past default or Event
of Default hereunder and its consequences except (i) a default in the payment of
interest or premium, if any, on, or the principal of, the Notes when due, (ii) a
failure by the Company to convert any Notes into Common Stock or (iii) a default
in respect of a covenant or provisions hereof which under Article XI cannot be
modified or amended without the consent of all affected holders of Notes then
outstanding. Upon any such waiver the Company, the Trustee and the holders of
the Notes shall be restored to their former positions and rights hereunder; said
default or Event of Default shall for all purposes of the Notes and this
Indenture be deemed to have been cured and to be not continuing; but no such
waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent thereon.

        Section 7.8 Notice of Defaults

        The Trustee shall, within ninety (90) days after the Trustee obtains
knowledge of the occurrence of a default, mail to all Noteholders, as the names
and addresses of such holders appear upon the Note register, notice of all
defaults actually known to a Responsible Officer, unless such defaults shall
have been cured or waived before the giving of such notice; and provided that,
except in the case of default in the payment of the principal of, or premium, if
any, or interest (including Liquidated Damages to the extent accrued but unpaid)
on any of the Notes, including without limiting the generality of the foregoing
any default in the payment of any Repurchase Price or in the payment of any
amount due in connection with any redemption of Notes, then in any such event
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 determine that the withholding of such notice is in the interests of the
Noteholders.

        Section 7.9 Undertaking to Pay Costs

        All parties to this Indenture agree, and each holder of any Note by his
acceptance thereof shall be deemed to have agreed, that any court may, in its
discretion, require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant;
provided that the provisions of this Section 7.9 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 25% in principal amount of the
Notes at the time outstanding determined in accordance with Section 9.4, or to
any suit instituted by any Noteholder for the enforcement of the payment of the
principal of or premium, if any, or interest (including Liquidated Damages to
the extent accrued but unpaid) on any Note (including, but not limited to, the
redemption price or Repurchase Price with respect to the Notes being redeemed or
repurchased as provided in this Indenture) 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 XV.

        Section 7.10 Delay or Omission Not Waiver

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

                             CONCERNING THE TRUSTEE

        Section 8.1 Duties and Responsibilities of Trustee

        The Trustee, prior to the occurrence of an Event of Default and after
the curing or waiver of all Events of Default that may have occurred, undertakes
to perform such duties and only such duties as are specifically set forth in
this Indenture and the Trust Indenture Act. In case an Event of Default has
occurred (which has not been cured or waived) the Trustee shall exercise such of
the rights and powers vested in it by this Indenture, and use the same degree of
care and skill in their exercise, as a prudent person would exercise or use
under the circumstances in the conduct of such person's own affairs.

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

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

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

                      (2) in the absence of bad faith or willful misconduct on
               the part of the Trustee, the Trustee may conclusively rely, as to
               the truth of the statements and the correctness of the opinions
               expressed therein, upon any certificates or opinions furnished to
               the Trustee and conforming to the requirements of this Indenture;
               provided, however, in the case of any such certificates or
               opinions that by any provisions hereof are specifically required
               to be furnished to the Trustee, the Trustee shall be under a duty
               to examine the same to determine whether or not they conform to
               the requirements of this Indenture;

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

               (c) the Trustee shall not be liable to any Noteholder with
        respect to any action taken or omitted to be taken by it in good faith
        in accordance with the direction of the holders of not less than a
        majority in principal amount of the Notes at the time outstanding
        determined as provided in Section 9.4 relating to the time, method and
        place of conducting any proceeding for any remedy available to the
        Trustee, or exercising any trust or power conferred upon the Trustee,
        under this Indenture; and

                                      -48-
<PAGE>

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

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

        Section 8.2 Reliance on Documents, Opinions, Etc.

        Except as otherwise provided in Section 8.1:

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

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

               (c) the Trustee may consult with counsel of its selection, and
        any advice of such counsel or Opinion of Counsel as to matters of law
        shall be full and complete authorization and protection in respect of
        any action taken or omitted by it hereunder in good faith and in
        accordance with such advice or Opinion of Counsel if such counsel was
        selected with due care;

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

               (e) the Trustee shall not be bound to make any investigation into
        the facts or matters stated in any resolution, certificate, statement,
        instrument, opinion, report, notice, request, direction, consent, order,
        bond, debenture or other paper or document, but the Trustee, in its
        reasonable discretion, may make such further inquiry or investigation
        into such facts or matters as it may see fit, and, if the Trustee shall
        determine to make such further inquiry or investigation, it shall be
        entitled to examine the books, records and premises of the Company,
        personally or by agent or attorney; provided, however, that if the
        payment within a reasonable time to the Trustee of the costs, expenses
        or liabilities likely to be incurred by it in the making of such
        investigation is, in the opinion of the Trustee, not reasonably assured
        to the Trustee by the security afforded to it by the terms

                                      -49-
<PAGE>

        of this Indenture, the Trustee may require indemnity reasonably
        satisfactory to the Trustee from the Noteholders against such expenses
        or liability as a condition to so proceeding; the reasonable expenses of
        every such examination shall be paid by the Company or, if paid by the
        Trustee or any predecessor Trustee, shall be repaid by the Company upon
        demand;

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

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

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

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

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

In no event shall the Trustee be liable for any consequential loss or damage of
any kind whatsoever (including but not limited to lost profits), even if the
Trustee has been advised of the likelihood of such loss or damage and regardless
of the form of action unless such loss or damage results from the Trustee's
willful misconduct or gross negligence.

        Section 8.3 No Responsibility for Recitals, Etc.

        The recitals contained herein and in the Notes (except in the Trustee's
certificate of authentication) shall be taken as the statements of the Company,
and the Trustee assumes no responsibility for the correctness of the same. The
Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Notes. The Trustee shall not be accountable for the use or
application by the Company of any Notes or the proceeds of any Notes
authenticated and delivered by the Trustee in conformity with the provisions of
this Indenture.

        Section 8.4 Trustee, Paying Agents, Conversion Agents or Registrar May
Own Notes

        The Trustee, any paying agent, any conversion agent or Note registrar,
in its individual or any other capacity, may become the owner or pledgee of
Notes with the same rights it would have if it were not Trustee, paying agent,
conversion agent or Note registrar.

        Section 8.5 Monies to be Held in Trust

        Subject to the provisions of Section 13.4, all monies received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as may be agreed in writing from time to time by
the Company and the Trustee.

        Section 8.6 Compensation and Expenses of Trustee

        The Company covenants and agrees to pay to the Trustee from time to
time, and the Trustee shall be entitled to, such compensation as the Company and
the Trustee shall from time to time agree in writing for all services rendered
by it hereunder in any capacity (which shall not be limited by any provision of
law in regard to the compensation of a trustee of an express trust), and the
Company will pay or reimburse the Trustee upon its request for all reasonable
expenses, disbursements and advances reasonably incurred or made by the Trustee
in accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its agents and
counsel and of all Persons not regularly in its employ) except any such expense,
disbursement or advance as may arise from its negligence, willful misconduct or
bad faith. The Company also covenants to indemnify the Trustee or any
predecessor Trustee in any capacity under this Indenture and its agents and any
authenticating agent for, and to hold them harmless against, any and all loss,
damages, claims, liability or expense incurred without negligence, willful
misconduct or bad faith on the part of the Trustee or such agent or
authenticating agent, as the case may be, and arising out of or in connection
with the acceptance or administration of this trust or in any other capacity
hereunder, including the costs and expenses of defending themselves against any
claim (whether asserted by the Company, a Holder or any other Person) of
liability in the premises. The obligations of the Company under this Section 8.6
to compensate or indemnify the Trustee and to pay or reimburse the Trustee for
expenses, disbursements and advances shall be secured by a lien upon all
property and funds held or collected by the Trustee as such, except, subject to
the effect of Sections 4.3 and 7.5, funds held in trust herewith for the benefit
of the holders of particular Notes prior to the date of the accrual of such
unpaid compensation or indemnifiable claim. The obligation of the Company under
this Section 8.6 shall survive the satisfaction and discharge of this Indenture.
The indemnification provided in this Section 8.6 shall extend to the officers,
directors, agents and employees of the Trustee.

        When the Trustee and its agents and any authenticating agent incur
expenses or render services after an Event of Default specified in Section
7.1(i) or (j) occurs, the expenses and the

                                      -51-
<PAGE>

compensation for the services are intended to constitute expenses of
administration under any bankruptcy, insolvency or similar laws.

        Section 8.7 Officer's Certificate as Evidence

        Except as otherwise provided in Section 8.1, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or
omitting any action hereunder, such matter (unless other evidence in respect
thereof be herein specifically prescribed) may, in the absence of negligence,
willful misconduct, recklessness or bad faith on the part of the Trustee, be
deemed to be conclusively proved and established by an Officer's Certificate
delivered to the Trustee, and such Officer's Certificate, in the absence of
negligence, willful misconduct, recklessness or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken or omitted by
it under the provisions of this Indenture upon the faith thereof.

        Section 8.8 Conflicting Interests of Trustee

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

        Section 8.9 Eligibility of Trustee

        There shall at all times be a Trustee hereunder that shall be a Person
that is eligible pursuant to the Trust Indenture Act to act as such and has a
combined capital and surplus (together with its corporate parent) of at least
$50,000,000. If such Person publishes reports of condition at least annually,
pursuant to law or to the requirements of any supervising or examining
authority, then for the purposes of this Section 8.9, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time
the Trustee shall cease to be eligible in accordance with the provisions of this
Section 8.9, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article VIII.

        Section 8.10 Resignation or Removal of Trustee

               (a) The Trustee may at any time resign by giving written notice
        of such resignation to the Company and by mailing notice thereof to the
        holders of Notes at their addresses as they shall appear on the Note
        register. Upon receiving such notice of resignation, the Company shall
        promptly appoint a successor trustee by written instrument, in
        duplicate, executed by order of the Board of Directors, one copy of
        which instrument shall be delivered to the resigning Trustee and one
        copy to the successor trustee. If no successor trustee shall have been
        so appointed and have accepted appointment sixty (60) days after the
        mailing of such notice of resignation to the Noteholders, the resigning
        Trustee may, at the expense of the Company, petition any court of
        competent jurisdiction for the appointment of a successor trustee, or
        any Noteholder who has been a bona fide holder of a Note or Notes for at
        least six months may, subject to the provisions of Section 7.9, on
        behalf of himself and all others similarly

                                      -52-
<PAGE>

        situated, petition any such court for the appointment of a successor
        trustee. Such court may thereupon, after such notice, if any, as it may
        deem proper and prescribe, appoint a successor trustee.

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

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

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

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

        then, in any such case, the Company may by a Board Resolution remove the
        Trustee and appoint a successor trustee by written instrument, in
        duplicate, executed by order of the Board of Directors, one copy of
        which instrument shall be delivered to the Trustee so removed and one
        copy to the successor trustee, or, subject to the provisions of Section
        7.9, any Noteholder who has been a bona fide holder of a Note or Notes
        for at least six 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. Such
        court may thereupon, after such notice, if any, as it may deem proper
        and prescribe, remove the Trustee and appoint a successor trustee.

               (c) The holders of a majority in aggregate principal amount of
        the Notes at the time outstanding may at any time remove the Trustee and
        nominate a successor trustee which shall be deemed appointed as
        successor trustee unless within ten (10) days after notice to the
        Company of such nomination the Company objects thereto, in which case
        the Trustee so removed or any Noteholder, upon the terms and conditions
        and otherwise as in Section 8.10(a) provided, may, at the expense of the
        Company, petition any court of competent jurisdiction for an appointment
        of a successor trustee.

               (d) Any resignation or removal of the Trustee and appointment of
        a successor trustee pursuant to any of the provisions of this Section
        8.10 shall become effective upon acceptance of appointment by the
        successor trustee as provided in Section 8.11.

        Section 8.11  Acceptance by Successor Trustee

        Any successor trustee appointed as provided in Section 8.10 shall
execute, acknowledge and deliver to the Company and to its predecessor trustee
an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the predecessor trustee shall

                                      -53-
<PAGE>

become effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as trustee herein; but, nevertheless, on the written request of the
Company or of the successor trustee, the trustee ceasing to act shall, upon
payment of any amounts then due it pursuant to the provisions of Section 8.6,
execute and deliver an instrument transferring to such successor trustee all the
rights and powers of the trustee so ceasing to act. Upon request of any such
successor trustee, the Company shall execute any and all instruments in writing
for more fully and certainly vesting in and confirming to such successor trustee
all such rights and powers. Any trustee ceasing to act shall, nevertheless,
retain a lien upon all property and funds held or collected by such trustee as
such, except for funds held in trust for the benefit of holders of particular
Notes, to secure any amounts then due it pursuant to the provisions of Section
8.6.

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

        Upon acceptance of appointment by a successor trustee as provided in
this Section 8.11, each of the Company and the former trustee 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 notice within ten (10) days after acceptance
of appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company.

        Section 8.12 Succession by Merger, Etc.

        Any corporation or other entity 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 or other entity succeeding to all or substantially all
of the corporate trust business of the Trustee (including the trust created by
this Indenture), shall be the successor to the Trustee hereunder without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, provided that in the case of any corporation succeeding to all
or substantially all of the corporate trust business of the Trustee such
corporation shall be qualified under the provisions of Section 8.8 and eligible
under the provisions of Section 8.9.

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

        Section 8.13 Limitation on Rights of Trustee as Creditor

        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

against the Company (or any such other obligor).

                                   ARTICLE IX

                           CONCERNING THE NOTEHOLDERS

        Section 9.1 Action by Noteholders

        Whenever in this Indenture it is provided that the holders of a
specified percentage in aggregate principal amount of the Notes may take any
action (including the making of any demand or request, the giving of any notice,
consent or waiver or the taking of any other action), the fact that at the time
of taking any such action, the holders of such specified percentage have joined
therein may be evidenced (a) by any instrument or any number of instruments of
similar tenor executed by Noteholders in person or by agent or proxy appointed
in writing, or (b) by the record of the holders of Notes voting in favor thereof
at any meeting of Noteholders duly called and held in accordance with the
provisions of Article X, 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 solicitation of such action.

        Section 9.2 Proof of Execution by Noteholders

        Subject to the provisions of Sections 8.1, 8.2 and 10.5, proof of the
execution of any instrument by a Noteholder or his 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 Note register or by a
certificate of the Note registrar. The record of any Noteholders' meeting shall
be proved in the manner provided in Section 10.6.

        Section 9.3 Who Are Deemed Absolute Owners

        The Company, the Trustee, any 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 him
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) for the
purpose of receiving payment of or on account of the principal of, premium, if
any, and interest (including Liquidated Damages to the extent accrued but
unpaid) on such Note,

                                      -55-
<PAGE>

for conversion of such Note and for all other purposes; and neither the Company
nor the Trustee nor any authenticating agent nor any paying agent nor any
conversion agent nor any Note registrar shall be affected by any notice to the
contrary. All such payments so made to any holder for the time being, or upon
his order, shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for monies payable upon any
such Note.

        Section 9.4 Company-Owned Notes Disregarded

        In determining whether the holders of the requisite aggregate principal
amount of Notes have concurred in any direction, consent, waiver or other action
under this Indenture, Notes that are owned by the Company or any other obligor
on the Notes or by any Person directly or indirectly controlling or controlled
by or under direct or indirect common control with 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 actually 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 9.4 if the pledgee shall establish to the satisfaction
of the Trustee the pledgee's right to vote such Notes and that the pledgee is
not the Company, any other obligor on the Notes or a Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company or any such other obligor. In the case of a dispute as
to such right, any decision by the Trustee taken upon the advice of counsel
shall be full protection to the Trustee. Upon request of the Trustee, the
Company shall furnish to the Trustee promptly an Officer's Certificate listing
and identifying all Notes, if any, known by the Company to be owned or held by
or for the account of any of the above described Persons; and, subject to
Section 8.1, the Trustee shall be entitled to accept such Officer's Certificate
as conclusive evidence of the facts therein set forth and of the fact that all
Notes listed therein are not outstanding for the purpose of any such
determination.

        Section 9.5 Revocation of Consents; Future Holders Bound

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

supplemental indenture or the Trustee to be qualified under the Trust Indenture
Act prior to the time such qualification is in fact required under the terms of
the Trust Indenture Act or the Indenture has been qualified under the Trust
Indenture Act, nor shall it constitute any admission or acknowledgement by any

this Indenture.

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

        Section 12.3 Opinion of Counsel to be Given Trustee

        The Trustee, subject to Sections 8.1 and 8.2, shall receive an Officer's
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 XII.

                                  ARTICLE XIII

                     SATISFACTION AND DISCHARGE OF INDENTURE

        Section 13.1 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 of all of the Notes (other than any Notes
which 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 premium, if any, and interest (including Liquidated Damages, if
any) due or to become due to such date of maturity or redemption date, as the
case may be, and if in either case the Company shall also pay or cause to be
paid all other sums payable hereunder by the Company, then this Indenture shall
cease to be of further effect (except as to (i) remaining rights of registration
of transfer, substitution and exchange and conversion of Notes, (ii) rights
hereunder of Noteholders to receive payments of principal of and premium, if
any, and interest on, the Notes and the other rights, duties and obligations of
Noteholders, as beneficiaries hereof with respect to the amounts, if any, so
deposited with the Trustee and (iii) the rights, obligations and immunities of
the Trustee hereunder), and the Trustee, on demand of the Company accompanied by
an Officer's Certificate and an Opinion of Counsel as required by Section 17.5
and at the cost and expense of the Company, shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture; the Company,
however, hereby agreeing 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 13.2 Deposited Monies to be Held in Trust by Trustee

        Subject to Section 13.4, all monies deposited with the Trustee pursuant
to Section 13.1 shall be held in trust and applied by it to the payment, either
directly or through any paying agent (including the Company if acting as its own
paying agent), to the holders of the particular Notes for the payment or
redemption of which such monies have been deposited with the Trustee, of all
sums due and to become due thereon for principal and interest and premium, if
any.

        Section 13.3 Paying Agent to Repay Monies Held

        Upon the satisfaction and discharge of this Indenture, all monies then
held by any paying agent of the Notes (other than the Trustee) shall, upon
demand of the Company, be repaid to it or paid to the Trustee, and thereupon
such paying agent shall be released from all further liability with respect to
such monies.

        Section 13.4 Return of Unclaimed Monies

        Subject to the requirements of applicable law, any monies deposited with
or paid to the Trustee for payment of the principal of, premium, if any, or
interest on Notes and not applied but remaining unclaimed by the holders of
Notes for two (2) years after the date upon which the principal of, premium, if
any, or interest (including Liquidated Damages, if any) on such Notes, as the
case may be, shall have become due and payable, shall be repaid to the Company
by the Trustee on written 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 which such holder may
be entitled to collect unless an applicable abandoned property law designates
another Person.

        Section 13.5 Reinstatement

        If (i) the Trustee or the paying agent is unable to apply any money in
accordance with Section 13.2 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application and (ii) the holders of at least a majority in principal amount of
the then outstanding Notes so request by written notice to the Trustee, the
Company's obligations under this Indenture and the Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Section 13.1 until such
time as the Trustee or the paying agent is permitted to apply all such money in
accordance with Section 13.2; provided, however, that if the Company makes any
payment of interest on or principal of any Note following the reinstatement of
its obligations, the Company shall be subrogated to the rights of the holders of
such Notes to receive such payment from the money held by the Trustee or paying
agent.

                           NO RECOURSE AGAINST OTHERS

        Section 14.1 Indenture and Notes Solely Corporate Obligations

        No direct or indirect partner, employee, incorporator, stockholder,
director or officer, as such, past, present or future of the Company or any
successor corporation or any Subsidiary or any of the Company's Affiliates,
shall have any personal liability in respect of the obligations of the Company
under the Notes or this Indenture by reason of his, her or its status as such
partner, employee, incorporator, stockholder, director or officer. Each
Noteholder by accepting a Note waives and releases all such liability. Such
waiver and release are part of the consideration for the issuance of the Notes.

                                   ARTICLE XV

                               CONVERSION OF NOTES

        Section 15.1 Right to Convert

        Subject to and upon compliance with the provisions of this Indenture,
the holder of any Note shall have the right, at his option, at any time
following the date of original issuance of the Notes and prior to the close of
business on June 15, 2007 (except that, with respect to any Note or portion of a
Note that shall be called for redemption, such right shall terminate, except as
provided in the fifth paragraph of Section 15.2 and Section 3.4, at the close of
business on the last Business Day prior to the date fixed for redemption of such
Note or portion of a Note unless the Company shall default in payment due upon
redemption thereof), to convert the principal amount of any such Note, or any
portion of such principal amount which is $1,000 or an integral multiple
thereof, into that number of fully paid and non-assessable shares of Common
Stock (as such shares shall then be constituted) obtained by dividing the
principal amount of the Note or portion thereof surrendered for conversion by
the Conversion Price in effect at such time, by surrender of the Note so to be
converted in whole or in part in the manner provided in Section 15.2. 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 XV. A
Note with respect to which a holder has delivered a notice in accordance with
Section 16.2 regarding such holder's election to require the Company to
repurchase such holder's Notes following the occurrence of a Repurchase Event
may be converted in accordance with this Article XV only if such holder
withdraws such notice by delivering a written notice of withdrawal to the
Company prior to the close of business on the last Business Day prior to the day
fixed for repurchase. If the holder of any Note exercises the right of
conversion set forth in this Article XV prior to March 21, 2003, the Company
shall make an additional payment in cash to such holder with respect to the
Notes converted, in an amount (a "Holder Conversion Provisional Payment") equal
to $39.375 per each $1,000 principal amount of the Note, less the amount of any
interest actually paid on such Note prior to the Conversion Date (and, if such
Note is converted between a record date and the next

                                      -66-
<PAGE>

interest payment date, less interest payable on each $1,000 principal amount of
such Note on such interest payment date). The Company may pay any Holder
Conversion Provisional Payment required to be paid pursuant to this Indenture in
whole or in part in cash and/or through the issuance of Common Stock; provided
(i) that Common Stock used to pay any Holder Conversion Provisional Payment
shall be valued at ninety-five percent (95%) of the Current Market Price of the
Common Stock as of the date two (2) Business Days prior to the Conversion Date,
(ii) that a registration statement covering the resale of such Common Stock is
effective and available for resale of such Common Stock from the twenty-fifth
(25th) Trading Date prior to the Conversion Date to and including the Conversion
Date to the extent required under the Registration Rights Agreement and (iii)
such Common Stock is listed for trading on the Principal Market (as defined in
the Securities Purchase Agreement). Notwithstanding the foregoing, a Holder
Conversion Provisional Payment, or portion thereof, shall be paid solely in cash
if payment in shares of Common Stock when such shares are added to the sum of
(1) the shares of Common Stock issued or issuable upon conversion of all the
Notes and Warrants and (2) the shares of Common Stock issued as payment for any
Holder Conversion Provisional Payment paid pursuant to this Indenture, would
cause the Company to issue greater than 19.99% of its aggregate outstanding
capital stock as of June 21, 2002 unless the stockholders of the Company have
otherwise approved such greater issuance of Common Stock.

        Section 15.2 Exercise of Conversion Privilege; Issuance of Common Stock
on Conversion

        In order to exercise the conversion privilege with respect to any
Definitive Note, the holder of such Definitive Note then registered on the books
of the Company shall (i) deliver a written notice, in the form of the conversion
notice attached as Exhibit A to such Definitive Note, or a reasonable facsimile
thereof (the "Conversion Notice"), to the Company and the conversion agent, of
such holder's election to convert, which notice shall specify that all of such
Note shall be converted or the portion thereof to be converted (which shall be
$1,000 or an integral multiple thereof), (ii) if such Note or portion thereof is
surrendered for conversion during the period from the close of business on the
Business Day preceding the record date for any interest payment date through the
close of business on the Business Day next preceding such interest payment date,
pay by wire transfer of immediately available funds or other method acceptable
to the Company, an amount equal to the interest otherwise payable on such
interest payment date on the principal amount being converted (unless such Note
or portion thereof being converted shall have been called for redemption
pursuant to a redemption notice mailed to the Noteholders in accordance with
Section 3.2 or shall have become due prior to such interest payment date as a
result of a Repurchase Event); provided, however, that no such payment need be
made if (x) there shall exist at the time of conversion a default in the payment
of interest on the Notes, or (y) such converting holder holds a Definitive Note
and requests that such payment be netted against the interest payable with
respect to the converted Note on the next interest payment date, by notifying
the Company and the Trustee of such election not later than two (2) Business
Days prior to the earlier of the Conversion Date and such interest payment date,
and includes in such notification a representation and warranty in favor of the
Company to the effect the such holder has owned such Definitive Note at all
times from and after the Business Day preceding such record date, (iii) pay by
wire transfer of immediately available funds or other method acceptable to the
Company the transfer taxes, if any, required pursuant to Section 15.8,

                                      -67-
<PAGE>

and (iv) surrender the Definitive Note to be converted in whole or in part to a
common carrier for overnight delivery to the Company as soon as practicable
following such date (or an indemnification undertaking or other form of security
reasonably satisfactory to the Company with respect to the Definitive Note in
the case of its loss, theft or destruction). Anything herein to the contrary
notwithstanding, in the case of Global Securities, conversion notices may be
delivered and a Participant's interest in a Global Note may be surrendered for
conversion in accordance with the Applicable Procedures as in effect from time
to time. Each Note surrendered for conversion shall, unless the shares issuable
on conversion are to be issued in the same name as the registration of such
Note, be duly endorsed by, or be accompanied by instruments of transfer
(including a broker's letter regarding compliance with the prospectus delivery
requirement, if applicable) in form satisfactory to the Company duly executed
by, the holder or his duly authorized attorney.

        The Company shall use its best efforts to, within three (3) Business
Days after the Conversion Date (as defined below) with respect to any Note,
subject to compliance with any restrictions on transfer if shares issuable on
conversion are to be issued in a name other than that of the Noteholder (as if
such transfer were a transfer of the Note or Notes (or portion thereof) so
converted) (a)(i) in the case of a public resale of the Common Stock issuable
upon such conversion, at the holder's request, credit such aggregate number of
shares of Common Stock to which the holder shall be entitled to the holder's or
its designee's balance account with The Depository Trust Company through its
Deposit Withdrawal Agent Commission system or (ii) issue and deliver to the
address as specified in the Conversion Notice, a certificate or certificates in
such denominations as may be requested by the holder in the Conversion Notice,
registered in the name of the holder or its designee, for the number of shares
of Common Stock to which the holder shall be entitled upon such conversion, and
(b) deliver to such holder a check or cash in respect of (i) any fractional
interest in respect of a share of Common Stock arising upon such conversion, as
provided in Section 15.3 and (ii) the Holder Conversion Provisional Payment, if
any (which payment, if any, shall be paid no later than ten (10) Business Days
after the Conversion Date). In case any Note of a denomination greater than
$1,000 shall be surrendered for partial conversion, and subject to Section 2.3,
the Company shall execute and the Trustee shall authenticate and deliver to the
holder of the Note so surrendered, without charge to him, a new Note or Notes in
authorized denominations in an aggregate principal amount equal to the
unconverted portion of the surrendered Note.

        If the Company shall not have (a) delivered the number of shares of
Common Stock issued upon conversion of Notes by any holder and (b) made any
Holder Conversion Provisional Payment required pursuant to Section 15.1, within
five (5) Business Days after the Conversion Date with respect to such Notes, the
Company shall pay Liquidated Damages to such holder at the rate of one-half
percent (0.5%) per month of the outstanding principal amount of Notes so
converted by such holder.

        The conversion shall be deemed to have been effected as to any such Note
(or portion thereof) on the date on which the requirements set forth above in
this Section 15.2 have been satisfied as to such Note (or portion thereof) (such
date, the "Conversion Date"), and the Person in whose name any shares of Common
Stock shall be issuable upon such conversion shall be deemed to have become on
the Conversion Date the holder of record of the shares represented

                                      -68-
<PAGE>

thereby; provided, however, that any such surrender on any date when the stock
transfer books of the Company shall be closed shall constitute the Person in
whose name the certificates are to be issued as the record holder thereof for
all purposes on the next succeeding day on which such stock transfer books are
open, but such conversion shall be at the Conversion Price in effect on the date
upon which such Note shall be surrendered. For purposes of determining
satisfaction of the requirement set forth above with respect to the Conversion
Date for any Note, any facsimile required to be sent shall be deemed to have
been sent on a given day if such facsimile was received before 1:00 p.m., New
York City time, on such date, to the number listed above (unless a different
number is specified in a notice filed with the Trustee and mailed by the
Trustee, at the Company's expense, to each holder of the Notes at such holder's
address appearing in the Note register, as provided for in Section 2.5 of this
Indenture) and a confirmation of transmission of such facsimile is obtained.

        The Company shall pay in cash, on any Note or portion thereof
surrendered for conversion during the period from the close of business on any
interest payment date to which interest has been fully paid through the close of
business on the Business Day preceding the record date for the next such
interest payment date, accrued and unpaid interest, if any, on the Note or
portion thereof surrendered for conversion to, but excluding, the date of
conversion, and Liquidated Damages, if any. Any such payment of interest shall
be made with respect to such Note within ten (10) Business Days after the
Conversion Date. Notwithstanding the foregoing, any Note or portion thereof
surrendered for conversion during the period from the close of business on the
record date for any interest payment date through the close of business on the
Business Day next preceding such interest payment date shall (unless such Note
or portion thereof being converted shall have been called for redemption
pursuant to a redemption notice mailed to the Noteholders in accordance with
Section 3.2 or shall have become due prior to such interest payment date as a
result of a Repurchase Event) be accompanied by payment, in immediately
available funds or other funds acceptable to the Company, of an amount equal to
the interest otherwise payable on such interest payment date on the principal
amount being converted; provided, however, that no such payment need be made if
there shall exist at the time of conversion a default in the payment of interest
on the Notes. Nothing in this Section 15.2 shall affect the right of a Holder in
whose name any Note is registered at the close of business on a record date to
receive the interest payable on such Note on the related interest payment date
in accordance with the terms of this Indenture and the Note. Except as provided
in this Section 15.2, no adjustment shall be made for interest accrued on any
Note converted or for dividends on any shares issued upon the conversion of such
Note as provided in this Article.

        Section 15.3 Cash Payments in Lieu of Fractional Shares

        No fractional shares of Common Stock or scrip representing fractional
shares shall be issued upon conversion of Notes. If more than one Note shall be
surrendered for conversion at one time by the same holder, the number of full
shares which shall be issuable upon conversion thereof 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 for conversion. If any
fractional share of stock otherwise would be issuable upon the conversion of any
Note or Notes, the Company shall calculate and pay a cash adjustment in lieu of
such fractional share at the current market value thereof to the holder of
Notes. The current market value of a share of

                                      -69-
<PAGE>

Common Stock shall be the Closing Price on the first Trading Day immediately
preceding the day on which the Notes (or specified portions thereof) are deemed
to have been converted and such Closing Price shall be determined as provided in
Section 15.5(f).

        Section 15.4 Conversion Price

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

        Section 15.5 Adjustment of Conversion Price

        The Conversion Price shall be adjusted from time to time by the Company
as follows:

                (a) In case the Company shall hereafter pay a dividend or make a
        distribution to all holders of the outstanding Common Stock in shares of
        Common Stock, the Conversion Price 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
        shall be reduced by multiplying such Conversion Price by a fraction of
        which the numerator shall be the number of shares of Common Stock
        outstanding at the close of business on the Record Date (as defined in
        Section 15.5(f)) fixed for such determination and the denominator shall
        be the sum of such number of shares and the total number of shares
        constituting such dividend or other distribution, such reduction to
        become effective immediately after the opening of business on the day
        following the Record Date. If any dividend or distribution of the type
        described in this Section 15.5(a) is declared but not so paid or made,
        the Conversion Price shall again be adjusted to the Conversion Price
        which would then be in effect if such dividend or distribution had not
        been declared.

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

                (c) In case the Company shall issue rights or warrants to all
        holders of its outstanding shares of Common Stock entitling them to
        subscribe for or purchase shares of Common Stock at a price per share
        less than the Current Market Price (as defined in Section 15.5(f)) on
        the Record Date fixed for the determination of stockholders entitled to
        receive such rights or warrants, the Conversion Price shall be adjusted
        so that the same shall equal the price determined by multiplying the
        Conversion Price in effect at the

                                      -70-
<PAGE>

        opening of business on the date after such Record Date by a fraction of
        which the numerator shall be the sum of the number of shares of Common
        Stock outstanding at the close of business on the Record Date plus the
        number of shares that the aggregate offering price of the total number
        of shares so offered for subscription or purchase would purchase at such
        Current Market Price, and of which the denominator shall be the sum of
        the number of shares of Common Stock outstanding at the close of
        business on the Record Date plus the total number of additional shares
        of Common Stock so offered for subscription or purchase. Such adjustment
        shall become effective immediately after the opening of business on the
        day following the Record Date fixed for determination of stockholders
        entitled to receive such rights or warrants. To the extent that shares
        of Common Stock are not delivered pursuant to such rights or warrants,
        upon the expiration or termination of such rights or warrants the
        Conversion Price shall be readjusted to the Conversion Price that would
        then be in effect had the adjustments made upon the issuance of such
        rights or warrants been made on the basis of delivery of only the number
        of shares of Common Stock actually delivered. In the event that such
        rights or warrants are not so issued, the Conversion Price shall again
        be adjusted to be the Conversion Price that would then be in effect if
        such date fixed for the determination of stockholders entitled to
        receive such rights or warrants had not been fixed. In determining
        whether any rights or warrants entitle the holders to subscribe for or
        purchase shares of Common Stock at less than such Current Market Price,
        and in determining the aggregate offering price of such shares of Common
        Stock, there shall be taken into account any consideration received for
        such rights or warrants, the value of such consideration, if other than
        cash, to be determined in good faith by the Board of Directors.

                (d) In case the Company shall, by dividend or otherwise,
        distribute to all holders of its Common Stock shares of any class of
        capital stock of the Company (other than any dividends or distributions
        to which Section 15.5(a) applies) or evidences of its indebtedness or
        other assets (including securities, but excluding (1) any rights or
        warrants referred to in Section 15.5(c) and (2) dividends and
        distributions paid exclusively in cash (except as set forth in Section
        15.5(e) and (f), (the foregoing hereinafter in this Section 15.5(d)
        called the "Securities")), unless the Company elects to reserve such
        Securities for distribution to the Noteholders upon conversion of the
        Notes so that any such holder converting Notes will receive upon such
        conversion, in addition to the shares of Common Stock to which such
        holder is entitled, the amount and kind of such Securities which such
        holder would have received if such holder had converted its Notes into
        Common Stock immediately prior to the Record Date (as defined in Section
        15.5(f)) for such distribution of the Securities then, in each such
        case, the Conversion Price shall be reduced so that the same shall be
        equal to the price determined by multiplying the Conversion Price in
        effect immediately prior to the close of business on the Record Date (as
        defined in Section 15.5(f)) with respect to such distribution by a
        fraction of which the numerator shall be the Current Market Price
        (determined as provided in Section 15.5(f)) on such date less the fair
        market value (as determined by the Board of Directors, whose
        determination shall be conclusive and described in a Board Resolution)
        on such date of the portion of the Securities so distributed applicable
        to one share of Common Stock and the denominator shall be such Current
        Market Price, such reduction to become effective immediately prior to
        the opening of business on the day following the Record Date;

                                      -71-
<PAGE>

        provided, however, that in the event the then fair market value (as so
        determined) of the portion of the Securities so distributed applicable
        to one share of Common Stock is equal to or greater than the Current
        Market Price 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 of a Note (or any portion thereof) the
        amount of Securities such holder would have received had such holder
        converted such Note (or portion thereof) immediately prior to such
        Record Date. In the event that such dividend or distribution is not so
        paid or made, the Conversion Price shall again be adjusted to be the
        Conversion Price which would then be in effect if such dividend or
        distribution had not been declared. If the Board of Directors determines
        the fair market value of any distribution for purposes of this Section
        15.5(d) by reference to the actual or when issued trading market for any
        securities comprising all or part of such distribution, it must in doing
        so consider the prices in such market over the same period (the
        "Reference Period") used in computing the Current Market Price pursuant
        to Section 15.5(f) to the extent possible, unless the Board of Directors
        in a Board Resolution determines that determining the fair market value
        during the Reference Period would not be in the best interest of the
        Noteholder.

                In the event that the Company implements a new stockholder
        rights plan, such rights plan shall provide that upon conversion of the
        Notes the holders will receive, in addition to the Common Stock issuable
        upon such conversion, the rights issued under such rights plan as if the
        holders had converted the Notes prior to implementing the rights plan
        and notwithstanding the occurrence of an event causing such rights to
        separate from the Common Stock at or prior to the time of conversion.
        Any distribution of rights or warrants pursuant to a stockholder rights
        plan complying with the requirements set forth in the immediately
        preceding sentence of this paragraph shall not constitute a distribution
        of rights or warrants for the purposes of this Section 15.5(d).

                Rights or warrants distributed by the Company to all holders of
        Common Stock entitling the holders thereof to subscribe for or purchase
        shares of the Company's capital stock (either initially or under certain
        circumstances), which rights or warrants, until the occurrence of a
        specified event or events ("Trigger Event"): (i) are deemed to be
        transferred with such shares of Common Stock; (ii) are not exercisable;
        and (iii) are also issued in respect of future issuances of Common
        Stock, shall be deemed not to have been distributed for purposes of this
        Section 15.5(d) (and no adjustment to the Conversion Price under this
        Section 15.5(d) will be required) until the occurrence of the earliest
        Trigger Event. If such right or warrant is subject to subsequent events,
        upon the occurrence of which such right or warrant shall become
        exercisable to purchase different securities, evidences of indebtedness
        or other assets or entitle the holder to purchase a different number or
        amount of the foregoing or to purchase any of the foregoing at a
        different purchase price, then the occurrence of each such event shall
        be deemed to be the date of issuance and record date with respect to a
        new right or warrant (and a termination or expiration of the existing
        right or warrant without exercise by the holder 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 resulted in an
        adjustment to the Conversion Price under this

                                      -72-
<PAGE>

        Section 15.5(d), (1) in the case of any such rights or warrants that
        shall all have been redeemed or repurchased without exercise by any
        holders thereof, the Conversion Price shall be readjusted upon such
        final redemption or repurchase to give effect to such distribution or
        Trigger Event, as the case may be, as though it were a cash
        distribution, equal to the per share redemption or repurchase price
        received by a holder 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 all of which
        shall have expired or been terminated without exercise, the Conversion
        Price shall be readjusted as if such rights and warrants had never been
        issued.

                For purposes of this Section 15.5(d) and Sections 15.5(a) and
        (c), any dividend or distribution to which this Section 15.5(d) is
        applicable that also includes shares of Common Stock, or rights or
        warrants to subscribe for or purchase shares of Common Stock to which
        Section 15.5(c) applies (or both), shall be deemed instead to be (1) a
        dividend or distribution of the evidences of indebtedness, assets,
        shares of capital stock, rights or warrants other than such shares of
        Common Stock or rights or warrants to which Section 15.5(c) applies (and
        any Conversion Price reduction required by this Section 15.5(e) 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 Price
        reduction required by Sections 15.5(a) and (c) 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", "Record Date fixed for such determination" and
        "Record Date" within the meaning of Section 15.5(a) and as "the date
        fixed for the determination of stockholders entitled to receive such
        rights or warrants", "the Record Date fixed for the determination of the
        stockholders entitled to receive such rights or warrants" and "such
        Record Date" within the meaning of Section 15.5(c) and (B) any shares of
        Common Stock included in such dividend or distribution shall not be
        deemed "outstanding at the close of business on the date fixed for such
        determination" within the meaning of Section 15.5(a).

                (e) In case the Company shall, by dividend or otherwise,
        distribute to all holders of its Common Stock cash (excluding any cash
        that is distributed upon a merger or consolidation to which Section 15.7
        applies or as part of a distribution referred to in Section 15.5(d)), in
        an aggregate amount that, combined together with (1) the aggregate
        amount of any other such distributions to all holders of its Common
        Stock made exclusively in cash within the twelve (12) months preceding
        the date of payment of such distribution, and in respect of which no
        adjustment pursuant to this Section 15.5(e) has been made, and (2) the
        aggregate of any cash plus the fair market value (as determined by the
        Board of Directors, whose determination shall be conclusive and
        described in a Board Resolution) of consideration payable in respect of
        any tender offer by the Company or any of its subsidiaries for all or
        any portion of the Common Stock concluded within the twelve (12) months
        preceding the date of payment of such distribution, and in respect of
        which no adjustment pursuant to Section 15.5(f) has been made, exceeds
        6% of the product of the Current Market Price (determined as provided in
        Section 15.5(f)) on the

                                      -73-
<PAGE>

        Record Date with respect to such distribution times the number of shares
        of Common Stock outstanding on such date, then, and in each such case,
        immediately after the close of business on such date, the Conversion
        Price shall be reduced so that the same shall equal the price determined
        by multiplying the Conversion Price in effect immediately prior to the
        close of business on such Record Date by a fraction (i) the numerator of
        which shall be equal to the Current Market Price on the Record Date less
        an amount equal to the quotient of (x) such combined amount and (y) the
        number of shares of Common Stock outstanding on the Record Date and (ii)
        the denominator of which shall be equal to the Current Market Price on
        such date; provided, however, that in the event the portion of the cash
        so distributed applicable to one share of Common Stock is equal to or
        greater than the Current Market Price of the Common Stock on the Record
        Date, in lieu of the foregoing adjustment, adequate provision shall be
        made so that each Noteholder shall have the right to receive upon
        conversion of a Note (or any portion thereof) the amount of cash such
        holder would have received had such holder converted such Note (or
        portion thereof) immediately prior to such Record Date. In the event
        that such dividend or distribution is not so paid or made, the
        Conversion Price shall again be adjusted to be the Conversion Price that
        would then be in effect if such dividend or distribution had not been
        declared.

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

                        (1) "Closing Price" with respect to any securities on
                any day shall mean the closing sale price regular way on such
                day or, in case no such sale takes place on such day, the
                average of the reported closing bid and asked prices, regular
                way, in each case on the Nasdaq National Market or New York
                Stock Exchange, as applicable, or, if such security is not
                listed or admitted to trading on such National Market or
                Exchange, on the principal national security exchange or
                quotation system on which such security is quoted or listed or
                admitted to trading, or, if not quoted or listed or admitted to
                trading on any national securities exchange or quotation system,
                the average of the closing bid and asked prices of such security
                on the over-the-counter market on the day in question as
                reported by the National Quotation Bureau Incorporated, or a
                similar generally accepted reporting service, or if not so
                available, in such manner as furnished by any New York Stock
                Exchange member firm selected from time to time by the Board of
                Directors for that purpose, or a price determined in good faith
                by the Board of Directors, whose determination shall be
                conclusive and described in a Board Resolution.

                        (2) "Current Market Price" shall mean the average of the
                daily Closing Prices per share of Common Stock for the ten (10)
                consecutive Trading Days immediately prior to the date in
                question; provided, however, that (1) if the "ex" date (as
                hereinafter defined) for any event (other than the issuance or
                distribution requiring such computation) that requires an
                adjustment to the Conversion Price pursuant to Section 15.5(a),
                (b), (c), (d), or (e) occurs during such ten (10) consecutive
                Trading Days, the Closing Price for each Trading Day prior to
                the

                                      -74-
<PAGE>

                "ex" date for such other event shall be adjusted by multiplying
                such Closing Price by the same fraction by which the Conversion
                Price is so required to be adjusted as a result of such other
                event, (2) if the "ex" date for any event (other than the
                issuance or distribution requiring such computation) that
                requires an adjustment to the Conversion Price pursuant to
                Section 15.5(a), (b), (c), (d) or(e) occurs on or after the "ex"
                date for the issuance or distribution requiring such computation
                and prior to the day in question, the Closing Price for each
                Trading Day on and after the "ex" date for such other event
                shall be adjusted by multiplying such Closing Price by the
                reciprocal of the fraction by which the Conversion Price is so
                required to be adjusted as a result of such other event, and (3)
                if the "ex" date for the issuance or distribution requiring such
                computation is prior to the day in question, after taking into
                account any adjustment required pursuant to clause (1) or (2) of
                this proviso, the Closing Price for each Trading Day on or after
                such "ex" date shall be adjusted by adding thereto the amount of
                any cash and the fair market value (as determined by the Board
                of Directors in a manner consistent with any determination of
                such value for purposes of Section 15.5(d), whose determination
                shall be conclusive and described in a Board Resolution) of the
                evidences of indebtedness, shares of capital stock or assets
                being distributed applicable to one share of Common Stock as of
                the close of business on the day before such "ex" date. For
                purposes of this paragraph, the term "ex" date, (1) when used
                with respect to any issuance or distribution, means the first
                date on which the Common Stock trades regular way on the
                relevant exchange or in the relevant market from which the
                Closing Price was obtained without the right to receive such
                issuance or distribution 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. Notwithstanding
                the foregoing, whenever successive adjustments to the Conversion
                Price are called for pursuant to this Section 15.5, such
                adjustments shall be made to the Current Market Price as may be
                necessary or appropriate to effectuate the intent of this
                Section 15.5 and to avoid unjust or inequitable results as
                determined in good faith by the Board of Directors.

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

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

                                      -75-
<PAGE>

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

                (g) The Company may make such reductions in the Conversion
        Price, in addition to those required by Sections 15.5(a), (b), (c), (d)
        or (e), as the Board of Directors considers to be advisable to avoid or
        diminish any income tax to holders of Common Stock or rights to purchase
        Common Stock resulting from any dividend or distribution of stock (or
        rights to acquire stock) or from any event treated as such for income
        tax purposes.

                To the extent permitted by applicable law, the Company from time
        to time may reduce the Conversion Price by any amount for any period of
        time if the period is at least twenty (20) days, the reduction is
        irrevocable during the period and the Board of Directors shall have made
        a determination that such reduction would be in the best interests of
        the Company, which determination shall be conclusive and described in a
        Board Resolution. Whenever the Conversion Price is reduced pursuant to
        the preceding sentence, the Company shall mail to the holder of each
        Note at his last address appearing on the Note register provided for in
        Section 2.5 a notice of the reduction at least fifteen (15) days prior
        to the date the reduced Conversion Price takes effect, and such notice
        shall state the reduced Conversion Price and the period during which it
        will be in effect.

                (h) No adjustment in the Conversion Price shall be required
        under this Section 15.5 unless such adjustment would require an increase
        or decrease of at least 1% in such price; provided, however, that any
        adjustments which by reason of this Section 15.5(h) are not required to
        be made shall be carried forward and taken into account in any
        subsequent adjustment. All calculations under this Article XV shall be
        made by the Company and shall be made to the nearest cent or to the
        nearest one hundredth of a share, as the case may be. No adjustment need
        be made for a change in the par value or no par value of the Common
        Stock.

                (i) Whenever the Conversion Price is adjusted as provided in
        this Section 15.5, the Company shall promptly file with the Trustee and
        any conversion agent other than the Trustee an Officer's Certificate
        setting forth the Conversion Price after such adjustment and setting
        forth a brief statement of the facts requiring such adjustment. Promptly
        after delivery of such certificate, the Company shall prepare a notice
        of such adjustment of the Conversion Price setting forth the adjusted
        Conversion Price and the date on which each adjustment becomes effective
        and shall mail such notice of such adjustment of the Conversion Price to
        the holder of each Note at his last address appearing on the Note
        register provided for in Section 2.5, within twenty (20) days of the

                                      -76-
<PAGE>

        effective date of such adjustment. Failure to deliver such notice shall
        not effect the legality or validity of any such adjustment.

                (j) In any case in which this Section 15.5 provides that an
        adjustment shall become effective immediately after a Record Date for an
        event, the Company may defer until the occurrence of such event (i)
        issuing to the holder of any Note converted after such Record Date and
        before the occurrence of such event the additional shares of Common
        Stock issuable upon such conversion by reason of the adjustment required
        by such event over and above the Common Stock issuable upon such
        conversion before giving effect to such adjustment and (ii) paying to
        such holder any amount in cash in lieu of any fraction pursuant to
        Section 15.3.

                (k) For purposes of this Section 15.5, the number of shares of
        Common Stock at any time outstanding shall not include shares held in
        the treasury of the Company but shall include shares issuable in respect
        of scrip certificates issued in lieu of fractions of shares of Common
        Stock. The Company will not pay any dividend or make any distribution on
        shares of Common Stock held in the treasury of the Company.

        Section 15.6 One-Time Conversion Price Adjustment

                (a) In addition to any adjustments to the Conversion Price
        required to be made pursuant to Section 15.5, if 115% of the Average
        Market Price on February 21, 2003 (the "Adjustment Date") is less than
        the Conversion Price otherwise in effect on the Adjustment Date, the
        Conversion Price shall be decreased effective as of the Adjustment Date
        to an amount equal to the greater of (x) 115% of such Average Market
        Price and (y) 75% of the Conversion Price.

                (b) "Average Market Price" shall mean the average of the daily
        Closing Prices per share of Common Stock for the twenty (20) consecutive
        Trading Days immediately prior to the Adjustment Date; provided,
        however, that if the "ex" date (as defined in Section 15.5(f)(2)) for
        any event that requires an adjustment to the Conversion Price pursuant
        to Section 15.5 occurs during such twenty (20) consecutive Trading Days,
        the Closing Price for each Trading Day prior to the "ex" date for such
        other event shall be adjusted by multiplying such Closing Price by the
        same fraction by which the Conversion Price is so required to be
        adjusted as a result of such other event.

                (c) If the Conversion Price is adjusted as provided in Section
        15.6(a), the Company shall promptly file with the Trustee and any
        conversion agent other than the Trustee an Officers' Certificate setting
        forth the fact that an adjustment to the Conversion Price was made
        pursuant to this Section 15.6 and the Conversion Price after such
        adjustment. Promptly after delivery of such certificate, the Company
        shall prepare a notice of such adjustment of the Conversion Price
        setting forth the adjusted Conversion Price and the date on which such
        adjustment became effective and shall mail such notice to the holder of
        each Note at his last address appearing on the Note register provided
        for in Section 2.5, within twenty (20) days of the Adjustment Date.
        Failure to deliver such notice shall not affect the legality or validity
        of any such adjustment.

        Section 15.7 Effect of Reclassification, Consolidation, Merger or Sale

        Subject to the provisions of Article XVI, if any of the following events
occur, namely (i) any reclassification or change of the outstanding shares of
Common Stock (other than a change in par value, or from par value to no par
value, or from no par value to par value, or as a result of a subdivision or
combination), (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, securities or other property or assets (including cash) with
respect to or in exchange for such Common Stock (other than as a result of a
change in name, a change in par value or a change in the jurisdiction of
incorporation), (iii) any statutory exchange as a result of which holders of
Common Stock generally shall be entitled to receive stock, securities or other
property or assets (including cash) with respect to or in exchange for such
Common Stock (such transaction, a "Statutory Exchange"), or (iv) any sale or
conveyance of the properties and assets of the Company as, or substantially as,
an entirety to any other Person as a result of which holders of Common Stock
shall be entitled to receive stock, securities or other property or assets
(including cash) with respect to or in exchange for such Common Stock, then the
Company or the successor or purchasing Person, as the case may be, shall execute
with the Trustee a supplemental indenture (which shall comply with the Trust
Indenture Act as in force at the date of execution of such supplemental
indenture if such supplemental indenture is then required to so comply)
providing that such Note shall be convertible into the kind and amount of shares
of stock and other securities or property or assets (including cash) receivable
upon such reclassification, change, consolidation, merger, combination,
Statutory 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 available to
convert all such Notes) immediately prior to such reclassification, change,
consolidation, merger, combination, Statutory Exchange, sale or conveyance
assuming such holder of Common Stock did not exercise his rights of election, if
any, that holders of Common Stock who were entitled to vote or consent to such
transaction had as to the kind or amount of securities, cash or other property
receivable upon such consolidation, merger, combination, Statutory Exchange,
sale or conveyance (provided that, if the kind or amount of securities, cash or
other property receivable upon such consolidation, merger, combination,
Statutory Exchange, sale or conveyance is not the same for each share of Common
Stock in respect of which such rights of election shall not have been exercised
("non-electing share"), then for the purposes of this Section 15.7 the kind and
amount of securities, cash or other property receivable upon such consolidation,
merger, combination, Statutory 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 XV. If, in the case
of any such reclassification, change, consolidation, merger, combination,
Statutory Exchange, sale or conveyance, the stock or other securities and assets
receivable thereupon by a holder of shares of Common Stock include shares of
stock or other securities and assets of a Person other than the successor or
purchasing Person, as the case may be, in such reclassification, change,
consolidation, merger, combination, Statutory Exchange, sale or conveyance, then
such supplemental indenture shall also be executed by such other Person and
shall contain such additional provisions to protect the interests of the holders
of the Notes as the Board of Directors shall reasonably consider necessary by
reason of the foregoing, including to

                                      -78-
<PAGE>

the extent practicable the provisions providing for the repurchase rights set
forth in Article XVI herein.

        The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each holder of Notes, at his address appearing on the
Note register provided for in Section 2.5 of this Indenture, 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 15.7 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

        If this Section 15.7 applies to any event or occurrence, Section 15.5
shall not apply.

        Section 15.8 Taxes on Shares Issued

        The issue of stock certificates on conversions of Notes shall be made
without charge to the converting Noteholder for any tax in respect of the issue
thereof. The Company shall not, however, be required to pay any tax which may be
payable in respect of any transfer involved in the issue and delivery of stock
in any name other than that of the holder of any Note converted, and the Company
shall not be required to issue or deliver any such stock certificate unless and
until the Person or Persons requesting the issue thereof shall have paid to the
Company the amount of such tax or shall have established to the satisfaction of
the Company that such tax has been paid.

        Section 15.9 Reservation of Shares; Shares to be Fully Paid; Listing of
Common Stock

        The Company shall provide, free from preemptive rights, out of its
authorized but unissued shares or shares held in treasury, reserved for the
purpose of issuance, no less than one hundred five percent (105%) of the number
of shares of Common Stock needed to provide for the issuance of Common Stock
upon conversion of all of the Notes and upon exercise of all the Warrants
without regard to any limitations on conversions or exercise.

        The Company will not, by amendment of its certificate of incorporation
or through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities, or any other voluntary action, avoid
or seek to avoid the observance or performance of any of the terms to be
observed or performed by it hereunder. Without limiting the generality of the
foregoing, the Company (i) will not increase the par value of any shares of
Common Stock issuable upon conversion of the Notes above the Conversion Price
then in effect, (ii) will take all such actions as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and non-assessable shares of Common Stock upon conversion of the Notes and (iii)
will not take any action which results in any adjustment of the Conversion Price
if the total number of shares of Common Stock issuable after the conversion of
all of the Notes and exercise of all of the Warrants would exceed the total
number of shares of Common Stock then authorized by the Company's certificate of
incorporation and available for the purpose of issue upon such exercise.

                                      -79-
<PAGE>

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

        The Company is obligated to register the shares of Common Stock issuable
upon conversion of the Notes for resale under the Securities Act pursuant to the
Registration Rights Agreement. The shares of Common Stock issuable upon
conversion of the Notes shall constitute Registrable Securities (as such term is
defined in the Registration Rights Agreement). Each holder of Notes shall be
entitled to all of the benefits afforded to a holder of any such Registrable
Securities under the Registration Rights Agreement and such holder, by its
acceptance of a Note, agrees and shall agree to be bound by and to comply with
the terms and conditions of the Registration Rights Agreement applicable to such
holder as a holder of such Registrable Securities.

        The Company shall use commercially reasonable efforts to promptly secure
the listing of the shares of Common Stock issuable upon conversion of a Note
upon each national securities exchange and automated quotation system, if any,
upon which shares of Common Stock are then listed (subject to official notice of
issuance upon conversion of such Note) and shall use commercially reasonable
efforts to maintain, so long as any other shares of Common Stock shall be so
listed, such listing of all shares of Common Stock from time to time issuable
upon the conversion of all then outstanding Notes; and the Company shall use
commercially reasonable efforts to list on each national securities exchange or
automated quotation system, as the case may be, and shall maintain such listing
of, any other shares of capital stock of the Company issuable upon conversion of
the Notes if and so long as any shares of the same class shall be listed on such
national securities exchange or automated quotation system. The Company shall
pay all fees and expenses in connection with satisfying its obligations under
this Section 15.9.

        Except as otherwise specifically provided herein, prior to a
Noteholder's receipt of Common Stock upon conversion of a Note, the Noteholder
shall not be entitled, as such, to any rights of a stockholder of the Company,
including, without limitation, the right to vote or to consent to any action of
the stockholders of the Company, to receive dividends or other distributions, to
exercise any preemptive right or to receive dividends or other distributions, or
to receive any notice of meetings of stockholders of the Company, and shall not
be entitled to receive any notice of any proceedings of the Company. In
addition, nothing contained in this Indenture shall be construed as imposing any
liabilities on such holder to purchase any securities (upon conversion of a Note
or otherwise) or as a stockholder of the Company, whether such liabilities are
asserted by the Company or by creditors of the Company.

        Section 15.10 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 whether any
facts exist which may require any adjustment of the Conversion Price, or with
respect to the nature or extent or calculation of any such adjustment when made,
or with respect to the method employed, or herein or in any supplemental
indenture provided to be employed, in making the same. The Trustee and any other
conversion agent shall not be accountable with respect to the validity or value
(or the kind

                                      -80-
<PAGE>

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. Subject to the provisions of Section 8.1, 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. Without limiting the
generality of the foregoing, neither the Trustee nor any conversion agent shall
be under any responsibility to determine whether a supplemental indenture need
be entered into under Section 15.7 or the correctness of any provisions
contained in any supplemental indenture entered into pursuant to such section
relating either to the kind or amount of shares of stock or securities or
property (including cash) receivable by Noteholders upon the conversion of their
Notes after any event referred to in such Section 15.7 or to any adjustment to
be made with respect thereto, but, subject to the provisions of Section 8.1, may
accept as conclusive evidence of the correctness of any such provisions, and
shall be protected in relying upon, the Officer's 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 15.11 Notice to Holders Prior to Certain Actions

        In case:

                (a) the Company shall declare a dividend (or any other
        distribution) on its Common Stock; or

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

                (c) of any reclassification 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 2.5 of this Indenture, as promptly as possible but in any event at least
fifteen (15) days prior to the applicable date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution or rights or warrants, or, if a record is not to be
taken, the date as of which the holders of Common Stock of record to be entitled
to such dividend, distribution or rights are to be determined, or (y) the date
on which such reclassification, consolidation, merger,

                                      -81-
<PAGE>

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.
The Company shall also issue a press release in connection with any such event,
and shall use commercially reasonable efforts to have such press release
available on Bloomberg Business News. Failure to give such notice, or any defect
therein, shall not affect the legality or validity of such dividend,
distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up.

        Section 15.12 Company Right to Force Automatic Conversion.

        The Company may, at its option, automatically convert all of the Notes
(an "Automatic Conversion") at any time prior to June 21, 2005 if no Event of
Default has occurred and is continuing and the Closing Price per share of the
Common Stock has exceeded 150% of the Conversion Price then in effect for at
least fifteen (15) Trading Days within a period of twenty (20) consecutive
Trading Days ending five (5) Trading Days prior to the Automatic Conversion
Date, provided (i) that a registration statement covering the resale of the
Common Stock issuable upon such conversion (the "Conversion Shares") is
effective and available for resale of the Notes and the Common Stock issuable
upon conversion of Notes from the twenty-fifth (25th) Trading Date prior to the
Automatic Conversion Date to and including the Automatic Conversion Date to the
extent required under the Registration Rights Agreement and (ii) the Conversion
Shares are listed for trading on the Principal Market (as defined in the
Securities Purchase Agreement). If the Company exercises the right of conversion
set forth in this Section 15.12, the Company shall make an additional payment in
cash to each holder of Notes with respect to the Notes converted, in an amount
(the "Company Conversion Provisional Payment") equal to $157.50 per each $1,000
principal amount of the Note, less the amount of any interest actually paid on
such Note to the Conversion Date (and, if such Note is converted between a
record date and the next interest payment date, less interest payable on each
$1,000 principal amount of such Note on such interest payment date).

        Unless the Company shall have theretofore called for redemption all of
the Notes then outstanding, the Company shall give to all Noteholders by
mailing, first class postage prepaid, a notice (the "Automatic Conversion
Notice") of the Automatic Conversion not more than thirty (30) days and not less
than five (5) days before the Automatic Conversion Date to such Noteholders at
their last addresses as they shall appear upon the Notes register. Any notice
that is mailed in the manner herein provided shall be conclusively presumed to
have been duly given, whether or not the registered Noteholder receives the
notice. The Company shall also issue a press release regarding its election to
convert the Notes, and shall use commercially reasonable efforts to have such
press release available on Bloomberg Business News. In any case, failure to duly
give such notice to the holder of any Notes designated for redemption in whole
or in part, or any defect in the notice, shall not affect the validity of the
proceedings for the automatic conversion of any other Notes.

        Each Automatic Conversion Notice shall state:

                                      -82-
<PAGE>

                (a) the Automatic Conversion Date,

                (b) the CUSIP number(s) of the Note(s) to be automatically
        converted,

                (c) the place or places where such Notes are to be surrendered
        for conversion,

                (d) the Conversion Price then in effect, and

                (e) what portion (if any) of any Company Conversion Provisional
        Payment will be paid in Common Stock.

        If any of the foregoing provisions or other provisions of this Section
are inconsistent with applicable law, such law shall govern.

        In the event of an Automatic Conversion, the Company shall issue and
deliver a certificate or certificates for the number of full shares of Common
Stock issuable upon conversion of the Notes along with (a) any cash in respect
of any fractional shares of Common Stock otherwise issuable upon conversion and
(b) the Company Conversion Provisional Payment, if any, for payment to the
Noteholder as promptly after the Automatic Conversion Date as practicable in
accordance with the provisions of this Article XV.

        All Notes subject to the Automatic Conversion shall be delivered to the
Company to be canceled.

                                   ARTICLE XVI

                       REPURCHASE UPON A REPURCHASE EVENT

        Section 16.1 Repurchase Right

        If, at any time prior to June 15, 2007 there shall occur a Repurchase
Event, then each Noteholder shall have the right, at such holder's option, to
require the Company to repurchase all of such holder's Notes, or any portion
thereof (in principal amounts of $1,000 or integral multiples thereof), on the
date (the "repurchase date") that is thirty (30) calendar days after the date of
the Company Notice (as defined in Section 16.2 below) of such Repurchase Event
(or, if such 30th day is not a Business Day, the next succeeding Business Day).
Such repurchase shall be made in cash at a price equal to 105% of the principal
amount of Notes such holder elects to require the Company to repurchase,
together with accrued interest, if any, to the repurchase date (the "Repurchase
Price"); provided, however, that if such repurchase date is June 15 or December
15 then the interest payable on such date shall be paid to the holder of record
of the Note on the next preceding June 1 or December 1, respectively.
Notwithstanding anything in this Article XVI to the contrary, if a redemption
date pursuant to Article III shall occur prior to any repurchase date
established pursuant to a Company Notice under Section 16.2, provided that the
Company shall have deposited or set aside an amount of money sufficient to
redeem such Notes as set forth in Section 3.2 on or before such repurchase date,
all such Notes shall be redeemed pursuant to Article III and the repurchase
rights hereunder shall have no effect.

        Section 16.2 Notices; Method of Exercising Repurchase Right, Etc.

                (a) Unless the Company shall have theretofore called for
        redemption all of the outstanding Notes and deposited or set aside an
        amount of money sufficient to redeem such Notes on the redemption date
        as set forth in Section 3.2, on or before the fifth (5th) Business Day
        following the occurrence of a Repurchase Event, the Company or, at the
        written request of the Company, the Trustee, shall mail to all holders
        of record of the Notes a notice (the "Company Notice") in the form as
        prepared by the Company of the occurrence of the Repurchase Event and of
        the repurchase right set forth herein arising as a result thereof. The
        Company shall issue a press release with respect to such Repurchase
        Event, and shall use commercially reasonable efforts to have such press
        release available on Bloomberg Business News. The Company shall also
        deliver a copy of such notice of a repurchase right to the Trustee and
        cause a copy of such notice of a repurchase right, or a summary of the
        information contained therein, to be published once in a newspaper of
        general circulation in The City of New York. The Company Notice shall
        contain the following information:

                        (1) the repurchase date;

                        (2) the CUSIP number(s) of the Note(s) subject to the
                repurchase right;

                        (3) the date by which the repurchase right must be
                exercised;

                        (4) the last date by which the election to require
                repurchase, if submitted, must be revoked;

                        (5) the Repurchase Price;

                        (6) a description of the procedure which a holder must
                follow to exercise a repurchase right; and

                        (7) the Conversion Price then in effect, the date on
                which the right to convert the principal amount of the Notes to
                be repurchased will terminate and the place or places where
                Notes may be surrendered for conversion.

        No failure of the Company to give the foregoing notices or defect
therein shall limit any holder's right to exercise a repurchase right or affect
the validity of the proceedings for the repurchase of Notes.

        If any of the foregoing provisions are inconsistent with applicable law,
such law shall govern.

                (b) To exercise a repurchase right, a holder shall deliver to
        the Trustee on or before the close of business on the thirty-fifth
        (35th) day after the Company Notice was mailed (i) written notice to the
        Company (or agent designated by the Company for such purpose) of the
        holder's exercise of such right, which notice shall set forth the name
        of

                                      -84-
<PAGE>

        the holder, the principal amount of the Notes to be repurchased, a
        statement that an election to exercise the repurchase right is being
        made thereby, and (ii) the Notes with respect to which the repurchase
        right is being exercised, duly endorsed for transfer to the Company.
        Election of repurchase by a holder shall be revocable at any time prior
        to, but excluding, the repurchase date, by delivering written notice to
        that effect to the Trustee prior to the close of business on the
        Business Day prior to the repurchase date.

                (c) If the Company fails to repurchase on the repurchase date
        any Notes (or portions thereof) as to which the repurchase right has
        been properly exercised, then the principal of such Notes shall, until
        paid, bear interest to the extent permitted by applicable law from the
        repurchase date at the rate borne by the Note and each such Note shall
        be convertible into Common Stock in accordance with this Indenture
        (without giving effect to Section 16.2(b)) until the principal of such
        Note shall have been paid or duly provided for.

                (d) Any Note that is to be repurchased only in part shall be
        surrendered to the Trustee duly endorsed for transfer to the Company and
        accompanied by appropriate evidence of genuineness and authority
        satisfactory to the Company and the Trustee duly executed by, the holder
        thereof (or his attorney duly authorized in writing), and the Company
        shall execute, and the Trustee shall authenticate and deliver to the
        holder of such Note without service charge, a new Note or Notes,
        containing identical terms and conditions, of any authorized
        denomination as requested by such holder in aggregate principal amount
        equal to and in exchange for the unrepurchased portion of the principal
        of the Note so surrendered.

                (e) On or prior to 10:00 a.m., New York City time on the
        repurchase date, the Company shall deposit with the Trustee or with a
        paying agent (or, if the Company is acting as its own paying agent,
        segregate and hold in trust as provided in Section 5.4) the Repurchase
        Price in cash for payment to the holder on the repurchase date.

                (f) If the Company is unable to repurchase on the repurchase
        date all of the Notes (or portions thereof) as to which the repurchase
        right has been properly exercised, the aggregate amount of Notes the
        Company may repurchase shall be allocated pro rata among each Note (or
        portion thereof) surrendered for repurchase, based on the principal
        amount of such Note, in proportion to the aggregate amount of Notes
        surrendered for repurchase.

                (g) All Notes delivered for repurchase shall be delivered to the
        Trustee to be canceled in accordance with the provisions of Section 2.8.

        Section 16.3 Certain Definitions

        For purposes of this Article XVI:

                (a) The term "beneficial owner" shall be determined in
        accordance with Rule 13d-3 and 13d-5, as in effect on the date of the

        pursuant to the Exchange Act.

                                      -85-
<PAGE>

                (b) The term "person" or "group" shall include any syndicate or
        group which would be deemed to be a "person" under Section 13(d) and
        14(d) of the Exchange Act as in effect on the date of the original
        execution of this Indenture.

                (c) The term "Continuing Director" means at any date a member of
        the Company's Board of Directors (i) who was a member of such board on
        June 21, 2002 or (ii) who was nominated or elected by at least a
        majority of the directors who were Continuing Directors at the time of
        such nomination or election or whose election to the Company's Board of
        Directors was recommended or endorsed by at least a majority of the
        directors who were Continuing Directors at the time of such nomination
        or election or such lesser number comprising a majority of a nominating
        committee if authority for such nominations or elections has been
        delegated to a nominating committee whose authority and composition have
        been approved by at least a majority of the directors who were
        Continuing Directors at the time such committee was formed. (Under this
        definition, if the Board of Directors of the Company as of the date of
        this Indenture were to approve a new director or directors and then
        resign, no Change in Control would occur even though all of the current

        office).

                (d) The term "Repurchase Event" means a Change in Control or a

        and 14(d) of the Exchange Act) is or becomes the beneficial owner of
        shares representing more than 50% of the combined voting power of the
        then outstanding securities entitled to vote generally in elections of
        directors of the Company (the "Voting Stock"); (ii) approval by the
        stockholders of the Company of any plan or proposal for the liquidation,
        dissolution or winding up of the Company; (iii) the Company (A)
        consolidates with or merges into any other corporation or any other
        corporation merges into the Company, and in the case of any such
        transaction, the outstanding Common Stock of the Company is changed or
        exchanged into other assets or securities as a result, unless the
        stockholders of the Company immediately before such transaction own,
        directly or indirectly immediately following such transaction, at least
        51% of the combined voting power of the outstanding voting securities of

indentures qualified under the Trust Indenture Act; provided, however, that this
Section 17.8 shall not require that this Indenture or the Trustee be qualified

        Section 17.11 Authenticating Agent

        The Trustee may appoint an authenticating agent which 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
2.4, 2.5, 2.6, 2.7 and 3.3, as fully for 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 8.9.

        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 all or substantially all of
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, without the execution or filing of any
paper or any further act on the part of the parties hereto or the authenticating
agent or such successor corporation.

        Any authenticating agent may at any time resign by giving written notice
of resignation to the Trustee and to the Company. The Trustee may at any time
terminate the agency of any authenticating agent by giving written notice of
termination to such authenticating agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee
shall promptly appoint a successor authenticating agent (which may be the
Trustee), shall give written notice of such appointment to the Company and shall
mail notice of such appointment 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
reasonable compensation for its services.

        The provisions of Sections 8.2, 8.3, 8.4, 9.3 and this Section 17.11
shall be applicable to any authenticating agent.

        Section 17.12 Execution in Counterparts

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

        Section 17.13 No Adverse Interpretation of Other Agreements.

        This Indenture may not be used to interpret another indenture, loan or
debt agreement of the Company or any Subsidiary of the Company. Any such
indenture, loan or debt agreement may not be used to interpret this Indenture.

Warrant may be exercised by the holder hereof then registered on the books of
the Company, in whole or in part, at any time on any Business Day on or after

on the Expiration Date by (i) delivery of a written notice, in the form of the
subscription notice attached as Exhibit A hereto or a reasonable facsimile
thereof (the "Exercise Notice"), to the Company and the Company's designated
transfer agent (the "Transfer Agent"), of such holder's election to exercise all
or a portion of this Warrant, which notice shall specify the number of Warrant
Shares to be purchased, (ii) (A) payment to the Company of an amount equal to
the Exercise Price multiplied by the number of Warrant Shares as to which this
Warrant is being exercised (the "Aggregate Exercise Price") in cash or delivery
of a certified check or bank draft payable to the order of the Company or wire
transfer of immediately available funds or (B) notification to the Company that
this Warrant is being exercised pursuant to a Cashless Exercise (as defined in
Section 2(e) of this Warrant), and (iii) the surrender of this Warrant to a
common carrier for overnight delivery to the Company as soon as practicable
following such date (or an indemnification undertaking or other form of security
reasonably satisfactory to the Company with respect to this Warrant in the case
of its loss, theft or destruction); provided, however, that if such Warrant
Shares are to be issued in any name other than that of the registered holder of
this Warrant, such issuance shall be deemed a transfer and the provisions of
Section 8 of this Warrant shall be applicable. In the event of any exercise of
the rights represented by this Warrant in compliance with this Section 2(a), the
Company shall use its best efforts on or before the third Business Day, but in
no event later than the fifth Business Day (the "Warrant Share Delivery Date")
following the date of its receipt of the Exercise Notice, the Aggregate Exercise
Price (or notice of Cashless Exercise) and this Warrant (or an indemnification
undertaking or other form of security reasonably satisfactory to the Company
with respect to this Warrant in the case of its loss, theft or destruction) (the
"Exercise Delivery Documents"), (A) in the case of a public resale of such
Warrant Shares, at the holder's request, credit such aggregate number of shares
of Common Stock to which the holder shall be entitled to the holder's or its
designee's balance account with the Company's designated  warrant agent (the
"Warrant Agent") through its Deposit Withdrawal Agent Commission system or (B)
issue and deliver to the address as specified in the

                                      -3-
<PAGE>

Exercise Notice, a certificate or certificates in such denominations as may be
requested by the holder in the Exercise Notice, registered in the name of the
holder or its designee, for the number of shares of Common Stock to which the
holder shall be entitled upon such exercise. Upon delivery of the Exercise
Notice, this Warrant and Aggregate Exercise Price referred to in clause (ii)(A)
above or notification to the Company of a Cashless Exercise referred to in
Section 2(e) of this Warrant, the holder of this Warrant shall be deemed for all
corporate purposes to have become the holder of record of the Warrant Shares
with respect to which this Warrant has been exercised, irrespective of the date
of delivery of this Warrant as required by clause (iii) above or the
certificates evidencing such Warrant Shares. In the case of a dispute as to the
determination of the Exercise Price or the arithmetic calculation of the number
of Warrant Shares, the Company shall promptly issue to the holder the number of
shares of Common Stock that is not disputed and shall submit the disputed
determination or arithmetic calculation to the holder via facsimile within two
(2) Business Days after receipt of the holder's Exercise Notice. If the holder
and the Company are unable to agree upon the determination of the Exercise Price
or arithmetic calculation of the number of Warrant Shares within two (2)
Business Days of such disputed determination or arithmetic calculation being
submitted to the holder, then the Company shall immediately submit via facsimile
(i) the disputed determination of the Exercise Price or the Closing Sale Price
(as defined in Section 9(f) of this Warrant) to an independent, reputable
investment banking firm selected jointly by the Company and the holder or (ii)
the disputed arithmetic calculation of the number of Warrant Shares to its
independent, outside auditor. The Company shall cause the investment banking
firm or the auditor, as the case may be, to perform the determination or
calculation and notify the Company and the holder of the results no later than
ten (10) Business Days from the time it receives the disputed determination or
calculation. Such investment banking firm's or auditor's determination or
calculation, as the case may be, shall be deemed conclusive absent manifest
error. All fees and expenses of such determinations shall be borne solely by the
Company.

      (b) Unless the rights represented by this Warrant shall have expired or
shall have been fully exercised, the Company shall, as soon as practicable but
in no event later than five (5) Business Days after any exercise (the "Warrant
Delivery Date") and at its own expense, issue a new Warrant identical in all
respects to this Warrant exercised except it shall represent rights to purchase
the number of Warrant Shares purchasable immediately prior to such exercise
under this Warrant, less the number of Warrant Shares with respect to which this
Warrant is exercised.

      (c) Notwithstanding anything contained in this Warrant to the contrary,
the Company shall not be required to issue fractions of shares of Common Stock
upon exercise of this Warrant or to distribute certificates which evidence such
fractional shares. If more than one Warrant shall be presented for exercise in
full at the same time by the same holder, the number of full shares of Common
Stock which shall be issuable upon the exercise thereof shall be computed on the
basis of the aggregate number of shares of Common Stock purchasable on exercise
of all Warrants so presented. In lieu of any fractional shares, there shall be
paid to the holder an amount of cash equal to the same fraction of the current
market value of a share of Common Stock. For purposes of this Section 2(c) of
this Warrant, the current market value of a share of Common Stock shall be the
Closing Sale Price of a share of Common Stock for the Trading Day immediately
prior to the date of such exercise or if not listed on a Principal Market, then
as determined by the holders of Warrants

                                      -4-
<PAGE>

representing a majority of the shares of Common Stock issuable upon exercise of
all of the Warrants then outstanding.

      (d) If the Company shall fail for any reason or for no reason (except in
the case of a dispute as to the Exercise Price or the Closing Sale Price which
is being resolved in accordance with Section 2(a) of this Warrant) to issue to
the holder within five (5) Business Days of receipt of the Exercise Delivery
Documents, a certificate for the number of shares of Common Stock to which the
holder is entitled or to credit the holder's or its designee's balance account
with the Warrant Agent, in accordance with Section 2 of this Warrant, for such
number of shares of Common Stock to which the holder is entitled upon the
holder's exercise of this Warrant or a new Warrant for the number of shares of
Common Stock to which such holder is entitled pursuant to Section 2(b) of this
Warrant, the Company shall, in addition to any other remedies under this Warrant
or the Securities Purchase Agreement or otherwise available to such holder,
including any indemnification under Section 8 of the Securities Purchase
Agreement, pay as additional damages in cash to such holder on each day after
the Warrant Share Delivery Date if such exercise is not timely effected and/or
each day after the Warrant Delivery Date if such Warrant is not delivered, as
the case may be, in an amount equal to one-half percent (0.5%) per month
multiplied by the product of (I) the sum of the number of shares of Common Stock
not issued to the holder on or prior to the Warrant Share Delivery Date and to
which such holder is entitled and, in the event the Company has failed to
deliver a Warrant to the holder on or prior to the Warrant Delivery Date and to
which such holder is entitled, the number of shares of Common Stock issuable
upon exercise of the Warrant as of the Warrant Delivery Date and (II) the
Closing Sale Price of the Common Stock on the Warrant Share Delivery Date, in
the case of failure to deliver Common Stock, or on the Warrant Delivery Date, in
the case of failure to deliver a Warrant, provided that if the Common Stock is
not listed on a Principal Market, then the Closing Sale Price shall be as
determined in good faith by a majority of the Company's Board of Directors,
whose determination shall be final, binding and conclusive.

      (e) Notwithstanding anything contained herein to the contrary, the holder
of this Warrant may, at its election exercised in its sole discretion, exercise
this Warrant as to all or a portion of the Warrant Shares and, in lieu of making
the cash payment otherwise contemplated to be made to the Company upon such
exercise in payment of the Aggregate Exercise Price, elect instead to receive
upon such exercise the "Net Number" of shares of Common Stock determined
according to the following formula (a "Cashless Exercise"):

                      Net Number = (A x B) - (A x C)
                                   -----------------
                                             B

      For purposes of the foregoing formula:

            A=    the total number of shares with respect to which this Warrant
                  is then being exercised.

            B=    the Closing Sale Price of the Common Stock on the Trading Day
                  immediately preceding the date of the Exercise Notice.

                                      -5-
<PAGE>

            C=    the Exercise Price then in effect for the applicable Warrant
                  Shares at the time of such exercise.

SECTION 3. DATE; DURATION; EARLY TERMINATION OF WARRANTS.

      (a) The date of this Warrant is June 21, 2002 (the "Warrant Date"). This
Warrant, in all events, shall be wholly void and of no effect at 5:00 pm,
Eastern Time, on the Expiration Date, or the Termination Date (as defined
below), if applicable, as the case may be, except that notwithstanding any other
provisions hereof, the provisions of Section 8(c) of this Warrant shall continue
in full force and effect after such date as to any Warrant Shares or other
securities issued upon the exercise of this Warrant.

      (b) At any time after June 21, 2005, if (1) the Closing Sale Price per
share of the Common Stock has exceeded 175% of the Exercise Price then in effect
for any fifteen (15) Trading Days within a period of twenty (20) consecutive
Trading Days (the "Determination Period") and (2) a shelf registration statement
covering resales of the Common Stock issuable upon exercise of the Warrants is
effective and available for use at all times during the period beginning thirty
(30) days prior to the Notice Date (as defined below) and ending on the
Termination Date, and is expected to remain effective and available for use
until at least the earlier of thirty (30) days following the Termination Date or
the last date on which the shelf registration statement is required to be kept
effective under the terms of the Registration Rights Agreement, then the Company
may, at its option, terminate the Warrants. By following the procedures set
forth below, the Company may exercise this right of termination only if, within
ten (10) days following the Determination Period, the Company shall mail or
cause to be mailed a notice of such termination (the "Termination Notice," and
the date such Termination Notice is mailed, the "Notice Date") to the holders of
the Warrant at the address set forth for such holder in Section 12 of this
Warrant. Such mailing shall be by first class mail and the Company shall
contemporaneously issue a press release through PRNewswire or Bloomberg
Financial Markets containing substantially the same information as the
Termination Notice described below. Each Termination Notice shall specify the
CUSIP number of the Warrant, the Termination Date, that the Warrants may not be
exercised after 5:00 p.m., Eastern Time, on the Termination Date and the current
Exercise Price.

      If all of the conditions described in the preceding paragraph have been
met and if no Event of Default (as that term is defined in the Indenture) shall
have occurred and be continuing under the Indenture, dated as of June 21, 2002
between the Company and The Bank of New York, as trustee (the "Indenture"), any
Warrant not exercised before the close of business on the ninetieth (90th) day
after the mailing date of the Termination Notice (such ninetieth (90th) day, the
"Termination Date") shall automatically be deemed exercised in accordance with
Section 2(e) of this Warrant and the Company will deliver the Warrant Shares to
the holder upon receipt of a completed Exercise Notice along with the original
copy of the Warrant for cancellation (or an affidavit of lost Warrant in
accordance with Section 11).

SECTION 4. COVENANTS AS TO COMMON STOCK. The Company hereby covenants and agrees
as follows:

                                      -6-
<PAGE>

      (a) Issuance of Warrants and Warrant Shares. This Warrant is, and any
Warrants issued in substitution for or replacement of this Warrant will, upon
issuance, be, validly issued, fully paid and non-assessable and free from all
taxes, liens and charges with respect to the issuance thereof, and shall not be
subject to preemptive rights or other similar rights of stockholders of the
Company. All Warrant Shares which may be issued upon the exercise of the rights
represented by this Warrant will, upon issuance and payment hereof or cashless
exercise in accordance with the terms hereof, be validly issued, fully paid and
nonassessable and free from all taxes, liens and charges created by or through
the Company with respect to the issue thereof, with the holders being entitled
to all rights accorded to a holder of Common Stock.

      (b) Reservation of Shares. During the period within which the rights
represented by this Warrant may be exercised, the Company will take all actions
reasonably necessary to at all times have authorized, and reserved for the
purpose of issuance, no less than one hundred five percent (105%) of the number
of shares of Common Stock needed to provide for the issuance of the Warrant
Shares upon exercise of all of the Warrants without regard to any limitations on
conversions or exercise.

      (c) Listing. The Company shall promptly use reasonable efforts to secure
the listing of the shares of Common Stock issuable upon exercise of this Warrant
upon each national securities exchange and automated quotation system, if any,
upon which shares of Common Stock are then listed (subject to official notice of
issuance upon exercise of this Warrant) and shall use reasonable efforts to
maintain, so long as any other shares of Common Stock shall be so listed, such
listing of all shares of Common Stock issuable from time to time upon the
exercise of this Warrant; and the Company shall use reasonable efforts to list
on the Principal Market or automated quotation system, as the case may be, and
shall use reasonable efforts to maintain such listing of, any other shares of
capital stock of the Company issuable upon the exercise of this Warrant if and
so long as any shares of the same class shall be listed on such Principal Market
or automated quotation system. The Company shall pay all fees and expenses in
connection with satisfying its obligations under this Section 4(c).

      (d) Certain Actions. The Company will not, by amendment of its certificate
of incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities, or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed by it hereunder. Without limiting the
generality of the foregoing, the Company (i) will not increase the par value of
any shares of Common Stock issuable upon the exercise of this Warrant above the
Exercise Price then in effect, (ii) will take all such actions as may be
reasonably necessary or appropriate in order that the Company may validly and
legally issue fully paid and nonassessable shares of Common Stock upon the
exercise of this Warrant and (iii) will not take any action which results in any
adjustment of the Exercise Price if the total number of shares of Common Stock
issuable after the action upon the exercise of all of the Warrants would exceed
the total number of shares of Common Stock then authorized by the Company's
certificate of incorporation and available for the purpose of issue upon such
exercise.

                                      -7-
<PAGE>

      (e) Obligations Binding on Successors. This Warrant will be binding upon
any entity succeeding to the Company in one or a series of transactions by
merger, consolidation or acquisition of all or substantially all of the
Company's assets or other similar transactions.

SECTION 5. TAXES.

      (a) The Company shall pay any and all documentary, stamp, transfer and
other similar taxes which may be payable with respect to the issuance and
delivery of Warrant Shares upon exercise of this Warrant.

      (b) Notwithstanding any other provision of this Warrant or any other
Transaction Document, for income tax purposes, any assignee or transferee shall
agree that the Company and the Transfer Agent shall be permitted to withhold
from any amounts payable to such assignee or transferee any taxes required by
law to be withheld from such amounts. Unless exempt from the obligation to do
so, each assignee or transferee shall execute and deliver to the Company or the
Transfer Agent, as applicable, a properly completed Form W-8 or W-9, indicating
that such assignee or transferee is not subject to back-up withholding for
United States Federal income tax purposes. Each assignee or transferee that does
not deliver such a form pursuant to the preceding sentence shall have the burden
of proving to the Company's reasonable satisfaction that it is exempt from such
requirement.

SECTION 6. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise
specifically provided herein, prior to the exercise of the Warrants represented
hereby, the holder of this Warrant shall not be entitled, as such, to any rights
of a stockholder of the Company, including, without limitation, the right to
vote or to consent to any action of the stockholders of the Company, to receive
dividends or other distributions, to exercise any preemptive right or to receive
dividends or other distributions, to exercise any preemptive right or to receive
any notice of meetings of stockholders of the Company, and shall not be entitled
to receive any notice of any proceedings of the Company. In addition, nothing
contained in this Warrant shall be construed as imposing any liabilities on such
holder to purchase any securities (upon exercise of this Warrant or otherwise)
or as a stockholder of the Company, whether such liabilities are asserted by the
Company or by creditors of the Company.

SECTION 7. COMPLIANCE WITH SECURITIES LAWS.

      (a) The holder of this Warrant, by the acceptance hereof, represents and
warrants that (i) it is acquiring this Warrant and (ii) upon exercise of this
Warrant will acquire the Warrant Shares then issuable upon exercise thereof for
its own account for investment only and not with a view towards, or for resale
in connection with, the public sale or distribution thereof, except pursuant to
sales registered or exempted from registration under the Securities Act;
provided, however, that by making the representations herein, the holder does
not agree to hold this Warrant or any of the Warrant Shares for any minimum or
other specific term and reserves the right to dispose of this Warrant and the
Warrant Shares at any time in accordance with or pursuant to a registration
statement or an exemption under the Securities Act. The holder of this Warrant
further represents, by acceptance hereof, that, as of this date, such holder is
an "accredited investor" as such term is defined in Rule 501(a) of Regulation D
promulgated by the Securities and Exchange Commission

                                      -8-
<PAGE>

under the Securities Act and was not organized for the specific purpose of
acquiring the Warrants or Warrant Shares.

      (b) This Warrant and all the Warrant Shares issued upon exercise hereof or
conversion thereof shall be stamped or imprinted with a legend in substantially
the following form (in addition to any legend required by state securities laws
or any securities exchange upon which such Warrant Shares may, at the time of
such exercise, be listed) on the face thereof unless at the time of exercise
such Warrant Shares shall be registered under the Securities Act:

      THE SECURITIES REPRESENTED BY THIS WARRANT HAVE NOT BEEN REGISTERED UNDER
      THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR
      APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR
      SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE
      REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OR
      APPLICABLE STATE SECURITIES LAWS OR AN EXEMPTION THEREFROM. THE SECURITIES
      MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN
      SECURED BY THE SECURITIES.

      In addition, any Warrants or Warrant Shares held by or transferred to an
"affiliate" (as defined in Rule 501(b) of Regulation D under the Securities Act)
of the Company shall be stamped or imprinted with a legend substantially in the
following form:

      THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE HELD BY A PERSON WHO
      MAY BE DEEMED TO BE AN AFFILIATE OF THE ISSUER FOR PURPOSES OF RULE 144
      PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
      ACT"), AND MAY BE SOLD ONLY IN COMPLIANCE WITH RULE 144, PURSUANT TO AN
      EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO A
      VALID EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT.

      The legends set forth above shall be removed and the Company (in the case
of Warrants) or the Transfer Agent (in the case of Warrant Shares) shall issue a
new Warrant or Warrant(s) of like tenor and aggregate principal amount, or a
certificate or certificates representing Warrant Shares, as appropriate, without
such legends to the holder of the Warrant(s) or Warrant Shares upon which they
are stamped, (i) if such Warrant(s) or Warrant Shares are registered for resale
under the Securities Act and are transferred or sold pursuant to such
registration, (ii) if, pursuant to a sale transaction, such holder provides the
Company with an opinion of counsel reasonably acceptable to the Company to the
effect that a public sale, assignment or transfer of the Warrant(s) or Warrant
Shares may be made without registration under the Securities Act, or (iii) if
the holder of the Securities has not been an "affiliate" (as defined in Rule
501(b) of Regulation D under the Securities Act) during the preceding three (3)
months, upon expiration of the two- (2) year period under Rule 144(k)
promulgated under the Securities Act (or any successor rule). In the event Rule
144(k) (or any successor rule) is amended to change the two- (2) year or three-
(3) month periods, the reference(s) in the preceding sentence shall be deemed to
be a reference to such changed period(s), provided that

                                      -9-
<PAGE>

such change shall not become effective if it is otherwise prohibited by, or
would otherwise cause a violation of, the then applicable federal securities
laws. The Company shall not require such opinion of counsel for the sale of
Warrant(s) or Warrant Shares in accordance with Rule 144 of the Securities Act,
provided the seller provides such representations that the Company shall
reasonably request confirming compliance with the requirements of Rule 144.

SECTION 8. OWNERSHIP AND TRANSFER.

      (a) The Company shall maintain at its principal executive offices (or such
other office or agency of the Company as it may designate by notice to the
holder hereof), a register for this Warrant (the "Warrant Register"), in which
the Company shall record the name and address of the Person in whose name this
Warrant has been issued, as well as the name and address of each transferee. The
Company may treat the Person in whose name any Warrant is registered on the
Warrant Register as the owner and holder thereof for all purposes,
notwithstanding any notice to the contrary, but in all events recognizing any
transfers made in accordance with the terms of this Warrant.

      (b) This Warrant and all rights hereunder shall be assignable and
transferable by the holder hereof without the consent of the Company upon
surrender of this Warrant with a properly executed assignment (in the form of
Exhibit B attached hereto) at the principal executive offices of the Company (or
such other office or agency of the Company as it may designate in writing to the
holder hereof).

      (c) The Company is obligated to register all of the Warrants and the
Warrant Shares for resale under the Securities Act pursuant to the Registration
Rights Agreement. The Warrants and the shares of Common Stock issuable upon
exercise of this Warrant shall constitute Registrable Securities (as such term
is defined in the Registration Rights Agreement). Each holder of this Warrant
shall be entitled to all of the benefits afforded to a holder of any such
Registrable Securities under the Registration Rights Agreement and such holder,
by its acceptance of this Warrant, agrees and shall agree to be bound by and to
comply with the terms and conditions of the Registration Rights Agreement
applicable to such holder as a holder of such Registrable Securities.

SECTION 9. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES ISSUABLE. The
Exercise Price, the number of Warrant Shares issuable upon the exercise of each
Warrant and the number of Warrants outstanding are subject to adjustment from
time to time upon the occurrence of the events enumerated in this Section 9.

      (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 Exercise Price in effect at the opening of business on the date
following the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be reduced by multiplying such
Exercise Price by a fraction of which (i) the numerator shall be the number of
shares of Common Stock outstanding at the close of business on the Record Date
(as defined in Section 9(f) of this Warrant) fixed for such determination and
(ii) the denominator shall be the sum of such number of shares and the total
number of shares constituting such dividend or other distribution, such
reduction in the

                                      -10-
<PAGE>

Exercise Price to become effective immediately after the opening of business on
the day following the Record Date. If any dividend or distribution of the type
described in this Section 9(a) of this Warrant is declared but not so paid or
made, the Exercise Price shall again be adjusted to the Exercise Price which
would then be in effect if such dividend or distribution had not been declared.

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

      (c) In case the Company shall issue rights or warrants to all holders of
its outstanding shares of Common Stock entitling them to subscribe for or
purchase shares of Common Stock at a price per share less than the Current
Market Price (as defined in Section 9(f) of this Warrant) on the Record Date
fixed for the determination of stockholders entitled to receive such rights or
warrants, the Exercise Price shall be adjusted so that the same shall equal the
price determined by multiplying the Exercise Price in effect at the opening of
business on the date after such Record Date 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 Record Date plus the number of shares that the
aggregate offering price of the total number of shares so offered for
subscription or purchase would purchase at such Current Market Price 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 Record Date plus the total
number of additional shares of Common Stock so offered for subscription or
purchase. Such adjustment shall become effective immediately after the opening
of business on the day following the Record Date fixed for determination of
stockholders entitled to receive such rights or warrants. To the extent that
shares of Common Stock are not delivered pursuant to such rights or warrants,
upon the expiration or termination of such rights or warrants, the Exercise
Price shall be readjusted to the Exercise Price that would then be in effect had
the adjustments made upon the issuance of such rights or warrants been made on
the basis of delivery of only the number of shares of Common Stock actually
delivered. In the event that such rights or warrants are not so issued, the
Exercise Price shall again be adjusted to be the Exercise Price that would then
be in effect if such date fixed for the determination of stockholders entitled
to receive such rights or warrants had not been fixed. In determining whether
any rights or warrants entitle the holders to subscribe for or purchase shares
of Common Stock at less than the Current Market Price, and in determining the
aggregate offering price of such shares of Common Stock, there shall be taken
into account any consideration received for such rights or warrants, the value
of such consideration, if other than cash, to be determined in good faith by the
Company's Board of Directors.

      (d) In case the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock shares of any class of capital stock of the Company
(other than any dividends or

                                      -11-
<PAGE>

distributions to which Section 9(a) of this Warrant applies) or evidences of its
indebtedness or other assets (including securities, but excluding (1) any rights
or warrants referred to in Section 9(c) of this Warrant and (2) dividends and
distributions paid exclusively in cash (except as set forth in Sections 9(e) and
9(f) of this Warrant, (the foregoing hereinafter in this Section 9(d) called the
"Securities")), unless the Company elects to reserve such Securities for
distribution to the holders upon exercise of the Warrants so that any such
holder converting Warrants will receive upon such exercise, in addition to the
shares of Common Stock to which such holder is entitled, the amount and kind of
such Securities which such holder would have received if such holder had
exercised its Warrants into Common Stock immediately prior to the Record Date
for such distribution of the Securities, then, in each such case, the Exercise
Price shall be reduced so that the same shall be equal to the price determined
by multiplying the Exercise Price in effect immediately prior to the close of
business on the Record Date with respect to such distribution by a fraction the
numerator of which shall be the Current Market Price (as defined in Section 9(f)
of this Warrant) on such date less the fair market value (as determined in good
faith by the Company's Board of Directors, whose determination shall be
conclusive) on such date of the portion of the Securities so distributed
applicable to one share of Common Stock and the denominator of which shall be
such Current Market Price, such reduction to become effective immediately prior
to the opening of business on the day following the Record Date; provided,
however, that in the event the then fair market value (as determined in good
faith by the Company's Board of Directors, whose determination shall be
conclusive) of the portion of the Securities so distributed applicable to one
share of Common Stock is equal to or greater than the Current Market Price on
the Record Date, in lieu of the foregoing adjustment, adequate provision shall
be made so that each holder shall have the right to receive upon conversion of a
Warrant (or any portion thereof) the amount of Securities such holder would have
received had such holder converted such Warrant (or portion thereof) immediately
prior to such Record Date.

      In the event that such dividend or distribution is not so paid or made,
the Exercise Price shall again be adjusted to be the Exercise Price which would
then be in effect if such dividend or distribution had not been declared. If a
majority of the independent members of the Company's Board of Directors
determines the fair market value of any distribution for purposes of this
Section 9(d) by reference to the actual or when issued trading market for any
securities comprising all or part of such distribution, it must in doing so
consider the prices in such market over the same period (the "Reference Period")
used in computing the Current Market Price pursuant to Section 9(f) of this
Warrant to the extent possible, unless a majority of the independent members of
the Company's Board of Directors determines in good faith that determining the
fair market value during the Reference Period would not be in the best interest
of the holders.

      In the event that the Company implements a new stockholder rights plan,
such rights plan shall provide that upon exercise of the Warrants the holders
will receive, in addition to the Common Stock issuable upon such exercise, the
rights issued under such rights plan (as if the holder had exercised the Warrant
prior to implementing the rights plan and notwithstanding the occurrence of an
event causing such rights to separate from the Common Stock at or prior to the
time of exercise). Any distribution of rights or warrants pursuant to a
stockholder rights plan complying with the

                                      -12-
<PAGE>

requirements set forth in the immediately preceding sentence of this paragraph
shall not constitute a distribution of rights or warrants for the purposes of
this Section 9(d).

      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 9(d) (and no adjustment to the Exercise Price under
this Section 9(d) will be required) until the occurrence of the earliest Trigger
Event. If such right or warrant is subject to subsequent events, upon the
occurrence of which such right or warrant shall become exercisable to purchase
different securities, evidences of indebtedness or other assets or entitle the
holder to purchase a different number or amount of the foregoing or to purchase
any of the foregoing at a different purchase price, then the occurrence of each
such event shall be deemed to be the date of issuance and record date with
respect to a new right or warrant (and a termination or expiration of the
existing right or warrant without exercise by the holder 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 resulted in an adjustment to the Exercise
Price under this Section 9(d), (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 Exercise Price shall be readjusted upon such final redemption or
repurchase to give effect to such distribution or Trigger Event, as the case may
be, as though it were a cash distribution, equal to the per share redemption or
repurchase price received by a holder 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 all of which shall
have expired or been terminated without exercise, the Exercise Price shall be
readjusted as if such rights and warrants had never been issued.

      For purposes of this Section 9(d) and Sections 9(a) and (c) of this
Warrant, any dividend or distribution to which this Section 9(d) is applicable
that also includes shares of Common Stock, or rights or warrants to subscribe
for or purchase shares of Common Stock to which Section 9(a) or (c) of this
Warrant applies (or both), shall be deemed instead to be (1) a dividend or
distribution of the evidences of indebtedness, assets, shares of capital stock,
rights or warrants other than such shares of Common Stock or rights or warrants
to which Section 9(c) of this Warrant applies (and any Exercise Price reduction
required by this Section 9(e) 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 Exercise
Price reduction required by Sections 9(a) and (c) of this Warrant 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," "Record Date fixed for such determination" and "Record Date"
within the meaning of Section 9(a) of this Warrant and as "the date fixed for
the determination of stockholders entitled to receive such rights or warrants,"
"the Record Date fixed for the determination of the stockholders

                                      -13-
<PAGE>

entitled to receive such rights or warrants" and "such Record Date" within the
meaning of Section 9(c) of this Warrant 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 9(a) of this Warrant.

      (e) In case the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock cash (excluding any cash that is distributed upon a
merger or consolidation to which Section 10 of this Warrant applies or as part
of a distribution referred to in Section 9(d) of this Warrant), in an aggregate
amount that, combined together with (1) the aggregate amount of any other such
distributions to all holders of its Common Stock made exclusively in cash within
the twelve (12) months preceding the date of payment of such distribution, and
in respect of which no adjustment pursuant to this Section 9(e) has been made,
and (2) the aggregate of any cash plus the fair market value (as determined in
good faith by the Company's Board of Directors, whose determination shall be
final, binding and conclusive) of consideration payable in respect of any tender
offer by the Company or any of its subsidiaries for all or any portion of the
Common Stock concluded within the twelve (12) months preceding the date of
payment of such distribution exceeds six percent (6%) of the product of the
Current Market Price (determined as provided in Section 9(f) of this Warrant) on
the Record Date with respect to such distribution times the number of shares of
Common Stock outstanding on such date, then, and in each such case, immediately
after the close of business on such date, the Exercise Price shall be reduced so
that the same shall equal the price determined by multiplying the Exercise Price
in effect immediately prior to the close of business on such Record Date by a
fraction (i) the numerator of which shall be equal to the Current Market Price
on the Record Date less an amount equal to the quotient of (x) such combined
amount and (y) the number of shares of Common Stock outstanding on the Record
Date and (ii) the denominator of which shall be equal to the Current Market
Price on such date; provided, however, that in the event the portion of the cash
so distributed applicable to one share of Common Stock is equal to or greater
than the Current Market Price of the Common Stock on the Record Date, in lieu of
the foregoing adjustment, adequate provision shall be made so that each holder
shall have the right to receive upon exercise of a Warrant (or any portion
thereof) the amount of cash such holder would have received had such holder
exercised such Warrant (or portion thereof) immediately prior to such Record
Date. In the event that such dividend or distribution is not so paid or made,
the Exercise Price shall again be adjusted to be the Exercise Price that would
then be in effect if such dividend or distribution had not been declared.

      (f) For purposes of this Section 9, the following terms shall have the
meanings indicated:

            (1) "Closing Sale Price" with respect to any securities on any day
shall mean the closing sale price regular way on such day or, in case no such
sale takes place on such day, the average of the reported closing bid and asked
prices, regular way, in each case on the Principal Market, or, if not quoted or
listed or admitted to trading on any national securities exchange or quotation
system, the average of the closing bid and asked prices of such security on the
over-the-counter market on the day in question as reported by the National
Quotation Bureau Incorporated, or a similar generally accepted reporting
service, or if not so available, in such manner as furnished by

                                      -14-
<PAGE>

any New York Stock Exchange member firm selected from time to time by the
Company's Board of Directors for that purpose, whose determination shall be
conclusive.

            (2) "Current Market Price" shall mean the average of the daily
Closing Sale Prices per share of Common Stock for the ten (10) consecutive
Trading Days immediately prior to the date in question; provided, however, that
(1) if the "ex" date (as hereinafter defined) for any event (other than the
issuance or distribution requiring such computation) that requires an adjustment
to the Exercise Price pursuant to Section 9(a), (b), (c), (d) or (e) of this
Warrant occurs during such ten (10) consecutive Trading Days, the Closing Sale
Price for each Trading Day prior to the "ex" date for such other event shall be
adjusted by multiplying such Closing Sale Price by the same fraction by which
the Exercise Price is so required to be adjusted as a result of such other
event, (2) if the "ex" date for any event (other than the issuance or
distribution requiring such computation) that requires an adjustment to the
Exercise Price pursuant to Section 9(a), (b), (c), (d) or (e) of this Warrant
occurs on or after the "ex" date for the issuance or distribution requiring such
computation and prior to the day in question, the Closing Sale Price for each
Trading Day on and after the "ex" date for such other event shall be adjusted by
multiplying such Closing Sale Price by the reciprocal of the fraction by which
the Exercise Price is so required to be adjusted as a result of such other
event, and (3) if the "ex" date for the issuance or distribution requiring such
computation is prior to the day in question, after taking into account any
adjustment required pursuant to clause (1) or (2) of this proviso, the Closing
Sale Price for each Trading Day on or after such "ex" date shall be adjusted by
adding thereto the amount of any cash and the fair market value (as determined
in good faith by the Company's Board of Directors in a manner consistent with
any determination of such value for purposes of Section 9(d) of this Warrant,
whose determination shall be conclusive) of the evidences of indebtedness,
shares of capital stock or assets being distributed applicable to one share of
Common Stock as of the close of business on the day before such "ex" date. For
purposes of 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. Notwithstanding the foregoing,
whenever successive adjustments to the Exercise Price are called for pursuant to
this Section 9, such adjustments shall be made to the Current Market Price as
may be necessary or appropriate to effectuate the intent of this Section 9 and
to avoid unjust or inequitable results as determined in good faith by the
Company's Board of Directors.

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

            (4) "Record Date" shall mean, with respect to any dividend,
distribution or other transaction or event in which the holders of Common Stock
have the right to receive any cash, securities or other property or in which the
Common Stock (or other applicable security) is exchanged for or converted into
any combination of cash, securities or other property, the date fixed

                                      -15-
<PAGE>

for determination of stockholders entitled to receive such cash, securities or
other property (whether such date is fixed by the Company's Board of Directors
or by statute, contract or otherwise).

      (g) The Company may make such reductions in the Exercise Price, in
addition to those required by Section 9(a), (b), (c), (d) or (e) of this
Warrant, as the Company's Board of Directors considers to be advisable to avoid
or diminish any income tax to holders of Common Stock or rights to purchase
Common Stock resulting from any dividend or distribution of stock (or rights to
acquire stock) or from any event treated as such for income tax purposes.

      (h) To the extent permitted by applicable law, the Company from time to
time may reduce the Exercise Price by any amount for any period of time if the
period is at least twenty (20) days, the reduction is irrevocable during such
period and the Company's Board of Directors shall have made a determination that
such reduction would be in the best interests of the Company, which
determination shall be conclusive and described in a Board Resolution. Whenever
the Exercise Price is reduced pursuant to the preceding sentence, the Company
shall mail to the holder of each Warrant at his last address in the Warrant
Register a notice of the reduction at least fifteen (15) days prior to the date
the reduced Exercise Price is to take effect, and such notice shall state the
reduced Exercise Price and the period during which it will be in effect.

      (i) No adjustment in the Exercise Price shall be required under this
Section 9 unless such adjustment would require an increase or decrease of at
least one percent (1%) in the Exercise Price; provided, however, that any
adjustments which by reason of this Section 9(i) are not required to be made
shall be carried forward and taken into account in any subsequent adjustment.
All calculations under this Section 9 shall be made by the Company and shall be
made to the nearest cent or to the nearest one hundredth of a share, as the case
may be. No adjustment need be made for a change in the par value of the Common
Stock.

      (j) Notice to Holders of Warrants Prior to Certain Actions. In case:

            (1) the Company shall declare a dividend (or any other distribution)
on its Common Stock that would require an adjustment in the Exercise Price
pursuant to this Section 9; or

            (2) the Company shall authorize the granting to the holders 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

            (3) of any reclassification of the Common Stock of the Company
(other than a subdivision or combination of its outstanding Common Stock, or a
change from par value to no 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 and transfer of all or substantially all of
the assets of the Company; or

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

                                      -16-
<PAGE>

      the Company shall mail to the holder at such address appearing in the
Warrant Register as promptly as possible but in any event at least fifteen (15)
days prior to the applicable date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution or rights 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 and the Company shall contemporaneously
issue a press release through PRNewswire or Bloomberg Financial Markets
containing substantially the same information as the notice described above.
Failure to give such notice, or any defect therein, shall not affect the
legality or validity of such dividend, distribution, reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.
In addition, whenever the Exercise Price is adjusted as provided in this Section
9, the Company shall prepare a notice of such adjustment of the Exercise Price
setting forth the adjusted Exercise Price and the date on which each adjustment
becomes effective and shall mail such notice of such adjustment of the Exercise
Price to the holder of each Warrant at his last address in the Warrant Register
within twenty (20) days of the effective date of such adjustment. Failure to
deliver such notice shall not effect the legality or validity of any such
adjustment.

      (k) In any case in which this Section 9 provides that an adjustment shall
become effective immediately after a Record Date for an event, the Company may
defer until the occurrence of such event (i) issuing to the holder of any
Warrant exercised after such Record Date and before the occurrence of such event
the additional shares of Common Stock issuable upon such exercise by reason of
the adjustment required by such event over and above the Common Stock issuable
upon such conversion before giving effect to such adjustment and (ii) paying to
such holder any amount in cash in lieu of any fractions of shares of Common
Stock pursuant to Section 2(c) of this Warrant.

      (l) For purposes of this Section 9, the number of shares of Common Stock
at any time outstanding shall not include shares held in the treasury of the
Company but shall include shares issuable in respect of scrip certificates
issued in lieu of fractions of shares of Common Stock. The Company will not pay
any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.

      (m) Upon each adjustment of the Exercise Price pursuant to this Section 9,
each Warrant shall thereupon evidence the right to purchase that number of
shares of Common Stock (calculated to the nearest hundredth of a share) obtained
by multiplying the number of shares of Common Stock purchasable immediately
prior to such adjustment upon exercise of the Warrant by the Exercise Price in
effect immediately prior to such adjustment and dividing the product so obtained
by the Exercise Price in effect immediately after such adjustment. The
adjustment pursuant to this Section 9(m) to the number of shares of Common Stock
purchasable upon exercise of a Warrant shall be made each time an adjustment of
the Exercise Price is made pursuant to this Section 9 (or would be made but for
Section 9(k) of this Warrant).

SECTION 10. EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE. If any of
the following events occur, namely (i) any reclassification or change of the
outstanding shares of Common Stock (other than a change in par value, or from
par value to no par value, or from no par value to par value, or as a result of
a subdivision or combination), (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, securities or other property or assets
(including cash) with respect to or in exchange for such Common Stock (other
than as a result of a change in name, a change in par value or a change in the
jurisdiction of incorporation), (iii) any statutory exchange, as a result of
which holders of Common Stock generally shall be entitled to receive stock,
securities or other property or assets (including cash) with respect to or in
exchange for such Common Stock (such transaction, a "Statutory Exchange"), (iv)
any sale or conveyance of the properties and assets of the Company as, or
substantially as, an entirety to any other person as a result of which holders
of Common Stock shall be entitled to receive stock, securities 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 issue a replacement Warrant providing that such Warrant shall be
exercisable for the kind and amount of shares of stock and other securities or
property or assets (including cash) receivable upon such reclassification,
change, consolidation, merger, combination, Statutory Exchange, sale or
conveyance by a holder of a number of shares of Common Stock issuable upon
exercise of such Warrants (assuming, for such purposes, a sufficient number of
authorized shares of Common Stock available for issuance upon exercise of all
such Warrants) immediately prior to such reclassification, change,
consolidation, merger, combination, Statutory Exchange, sale or conveyance
assuming such holder of Common Stock did not exercise his rights of election, if
any, that holders of Common Stock who were entitled to vote or consent to such
transaction had as to the kind or amount of securities, cash or other property
receivable upon such consolidation, merger, combination, Statutory Exchange,
sale or conveyance (provided that, if the kind or amount of securities, cash or
other property receivable upon such consolidation, merger, combination,
Statutory Exchange, sale or conveyance is not the same for each share of Common
Stock in respect of which such rights of election shall not have been exercised
("non-electing share"), then for the purposes of this Section 10, the kind and
amount of securities, cash or other property receivable upon such consolidation,
merger, combination, Statutory 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 replacement Warrant shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in Section 9 of this Warrant. If, in
the case of any such reclassification, change, consolidation, merger,
combination, Statutory Exchange, sale or conveyance, the stock or other
securities and assets receivable thereupon by a holder of shares of Common Stock
shall include shares of stock or other securities and assets of a corporation
other than the successor or purchasing person, as the case may be, in such
reclassification, change, consolidate, merger, combination, Statutory Exchange,
sale or conveyance, then such replacement Warrant shall also be executed by such
other person and shall contain such additional provisions to protect the
interests of the holder of the Warrants as the Company's Board of Directors
shall reasonably consider necessary by reason of the foregoing. The Exercise
Price for the stock and other securities, property and assets (including cash)
so receivable upon such event shall be an amount equal to the Exercise Price
immediately prior to such event.

                                      -18-
<PAGE>

      The Company shall mail such replacement Warrant to each holder of
Warrants, at such holder's address appearing in the Warrant Register within
twenty (20) days after execution thereof. Failure to deliver such notice shall
not affect the legality or validity of such replacement Warrant.

      The above provisions of this Section 10 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

      If this Section 10 applies to any event or occurrence, Section 9 of this
Warrant shall not apply.

SECTION 11. LOST, STOLEN, MUTILATED OR DESTROYED WARRANTS. If this Warrant is
lost, stolen, mutilated or destroyed, the Company shall promptly, on receipt of
an indemnification undertaking or other form of security reasonably acceptable
to the Company (or in the case of a mutilated Warrant, the Warrant), issue a new
Warrant of like denomination and tenor as this Warrant so lost, stolen,
mutilated or destroyed. Notwithstanding the foregoing, if this Warrant is lost
by, stolen from or destroyed by the original holder hereof, the affidavit of
such original holder setting forth the circumstances of such loss, theft or
destruction shall be accepted as satisfactory evidence thereof, and no
indemnification bond or other security shall be required by the Company as a
condition to the execution and delivery by the Company of a new Warrant to such
original holder other than such original holder's unsecured written agreement to
indemnify the Company solely for losses actually incurred by the Company as a
direct consequence of the loss, theft or destruction of the Warrant.

SECTION 12. NOTICE. Any notices, consents, waivers or other communications
required or permitted to be given under the terms of this Warrant must be in
writing and will be deemed to have been delivered: (i) upon receipt, when
delivered personally; (ii) upon receipt, when sent by facsimile; or (iii) one
(1) Business Day after deposit with a nationally recognized overnight delivery
service, in each case properly addressed to the party to receive the same. If
notice is to be sent to the Company, the holder shall use its reasonable best
efforts to provide additional copies to the individuals listed below; provided,
however, that the failure of such holder to send such additional copies shall in
no way limit the effectiveness of any notice sent to the Company to the

signed by the Company and holders of a majority of Warrant Shares represented by
all Warrants. Such amendment, change, waiver, discharge or termination shall be
binding on the Company and all of the Warrant holder's assignees and

Price, including by a waiver of or an amendment to Section 9 of this Agreement,
or decrease the number of shares or class of stock issuable upon exercise of any
Warrants without the written consent of the holder of such Warrant. No waivers

laws of any jurisdictions other than the State of New York. Each party hereby
irrevocably submits to the non-exclusive jurisdiction of the state and federal

party at the address for such notices to it under this Warrant and agrees that
such service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right
