the Company and the holders of the Securities representing a majority of the
aggregate principal amount of the Securities then outstanding.

Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary
or impair, as between the Depositary and its Agent Members, the operation of
customary practices of such Depositary governing the exercise of the rights of a

to authenticate Securities. An authenticating agent may authenticate Securities

an Affiliate.

provided that no such designation 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, State of New York, for such purposes. The term "Paying Agent"
includes any additional paying agent and the term "Conversion Agent" includes
any additional conversion agent. The Company may change any Paying Agent,
Registrar, co-registrar or Conversion Agent without prior notice to any
Noteholder. The Company shall notify the Trustee of the name and address of any
Agent not a party to this Indenture. If the Company fails to appoint or maintain
another entity as Registrar, Paying Agent or Conversion Agent, the Trustee shall
act as such. The Company or any of its Affiliates may act as Paying Agent,
Registrar, co-registrar or Conversion Agent. The Company initially appoints the
Trustee as Paying Agent, Registrar, Conversion Agent and Custodian and the
Trustee hereby accepts such appointments and each of the Corporate Trust Office
of the Trustee at 101 Barclay Street, New York, NY 10286, Attention: Corporate
Trust Administration - Global Finance Unit.

each Paying Agent other than the Trustee to agree in writing that the Paying
Agent will hold in trust for the benefit of Noteholders or the Trustee all money
held by the Paying Agent for the payment of principal of, premium, if any, or
interest on the Securities, and will notify the Trustee of any default by the
Company in making any such payment. While any such default continues, the
Trustee may require a Paying Agent to pay all money held by it to the Trustee.
The Company at any time may require a Paying Agent to pay all money held by it
to the Trustee and to account for any money disbursed by it. Upon payment over
to the Trustee, the Paying Agent (if other than the Company or any Affiliate of
the Company) shall have no further liability for the money. If the Company or an
Affiliate of the Company acts as Paying Agent, it shall segregate and hold in a
separate trust fund for the benefit of the Noteholders all money held by it as
Paying Agent.

      Section 2.5 Noteholder Lists. The Trustee shall preserve in as current a
form as is reasonably practicable the most recent list available to it of the

and as of such date as the Trustee may reasonably require of the names and
addresses of Noteholders.

      Section 2.6 Transfer and Exchange. (a) Where Securities are presented to
the Registrar or a co-registrar with a request to register a transfer or to
exchange them for an equal principal amount of Securities of other
denominations, the Registrar shall register the transfer or make the exchange if
its requirements for such transactions are met. To permit registrations of
transfers and exchanges, the Company shall issue and the Trustee shall
authenticate Securities at the Registrar's request. No service charge shall be
made for any registration of transfer or exchange (except as otherwise expressly
permitted herein), but the Company may require payment of a sum sufficient to
cover any transfer tax or similar governmental charge payable in connection
therewith (other than any such transfer tax or similar governmental charge
payable upon exchanges pursuant to Sections 2.6, 2.10, 3.6 or 11.5 hereof).

      The Company and the Registrar shall not be required (i) to issue, register
the transfer of, or exchange Securities during a period beginning at the opening
of business 20 days before the day of any selection of Securities for redemption
under Section 3.2 hereof and ending at the

transfer of any Security so selected for redemption in whole or in part, except
the unredeemed portion of any Security being redeemed in part or (iii) to issue,
register the transfer of or exchange Securities submitted for repurchase (and
not withdrawn) under Section 4.7 hereof.

            (b) Restrictions on Transfer and Exchange of Global Securities. (i)
The transfer and exchange of Global Securities or beneficial interests therein
shall be effected through the Depositary, in accordance with this Indenture and
the procedures of the Depositary therefor. Notwithstanding the aforementioned, a
Global Security may not be transferred as a whole except by the Depositary to a
nominee of the Depositary or by a nominee of the Depositary to the Depositary or
another nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary.

                  (ii) Unless and until such time as a Security is sold pursuant

an exemption from the registration requirements of the Securities Act, the
following provisions shall apply:

                        (x) Transfers to Non-QIBs. The following provisions
shall apply with respect to the registration of any proposed transfer of a
Security bearing the Restricted Security Legend to any person that is not a QIB:

under the Securities Act) of the Company and (II) at least three months after
the last date such holder was an affiliate of the Company or (Y) the proposed
transferee has delivered to the Registrar a letter substantially in the form set
forth in Exhibit B hereto.

                              (B) If the proposed transferee is an Agent Member
and the Security bearing the Restricted Securities Legend to be transferred
consists of a beneficial interest in the QIB Global Security, upon receipt by
the Registrar of (X) the letter, if any, required by paragraph (A) above and (Y)
instructions given in accordance with the Depositary's and the Registrar's
procedures therefor, the Registrar shall reflect on its books and records the
date and an increase in the principal amount of the IAI Global Security in an
amount equal to the principal amount of the beneficial interest in the QIB
Global Security to be so transferred and the Registrar shall reflect on its
books and records the date and an appropriate decrease in the principal amount
of such QIB Global Security.

                        (y) Transfers to QIBs. The following provisions shall
apply with respect to the registration of any proposed transfer of a Security
bearing the Restricted Security Legend to a QIB:

                              (A) The Registrar shall register the transfer of
any Security bearing the Restricted Securities Legend by a holder to a QIB if
(X) the requested transfer is (I) at least two years after the later of (a) the
Issuance Date with respect to such


                                       13

Security and (b) the date such Security was acquired from an affiliate of the
Company and (II) at least three months after the last date such holder was an
affiliate of the Company or (Y) such transfer is being made by a proposed
transferor who has provided the Registrar with a letter substantially in the
form set forth in Exhibit C hereto.

                              (B) If the proposed transferee is an Agent Member
and the Security bearing the Restricted Securities Legend to be transferred
consists of an interest in the IAI Global Security, upon receipt by the
Registrar of (X) the letter, if any, required by paragraph (A) above and (Y)
instructions given in accordance with the Depositary's and the Registrar's
procedures therefor, the Registrar shall reflect on its books and records the
date and an increase in the principal amount of the QIB Global Security in an
amount equal to the principal amount of the beneficial interest in the IAI
Global Security to be so transferred, and the Registrar shall reflect on its
books and records the date and an appropriate decrease in the principal amount
of such IAI Global Security.

                        (iii) Restricted Securities Legend. Upon the transfer,
exchange or replacement of Securities not bearing the Restricted Securities
Legend, the Registrar shall deliver Securities that do not bear the Restricted
Securities Legend. Upon the transfer, exchange or replacement of Securities
bearing the Restricted Securities Legend, the Registrar shall deliver only
Securities bearing the Restricted Securities Legend unless either (i) the
circumstances contemplated by paragraph (b)(ii)(x)(A)(X) or (b)(ii)(y)(A)(X) of
this Section exist or (ii) there is delivered to the Registrar an Opinion of
Counsel reasonably satisfactory to the Company and the Trustee to the effect
that neither such legend nor the related restrictions on transfer are required
in order to maintain compliance with the provisions of the Securities Act. For
purposes hereof "Securities not bearing the Restricted Securities Legend"
includes beneficial interests in the Unrestricted Global Security, and
"Securities bearing the Restricted Securities Legend" includes beneficial
interests in the QIB Global Security and the IAI Global Security.

                        (iv) General. By its acceptance of any Security bearing
the Restricted Securities Legend, each holder of such Security acknowledges the
restrictions on transfer of such Security set forth in this Indenture and in the
Restricted Securities Legend and agrees that it shall transfer such Security
only as provided in this Indenture.

                        The Registrar shall retain copies of all letters,
notices and other written communications received pursuant to this Section 2.6.
The Company shall have the right to inspect and make copies of all such letters,
notices or other written communications at any reasonable time upon the giving
of reasonable written notice to the Registrar.

                  (c) Authentication of Certificated Security in Absence of
Depositary. If at any time that any Global Securities are outstanding:

                        (i) the Depositary for the Securities notifies the
Company that the Depositary is unwilling or unable to continue as Depositary for
the Global Securities and a successor Depositary for the Global Securities is
not appointed by the Company within 90 days after delivery of such notice; or


                                       14

                        (ii) an Event of Default has occurred and is continuing
then the Company shall execute, and the Trustee shall, upon receipt of an
authentication order in accordance with Section 2.2 hereof, authenticate and
deliver, certificated Securities in an aggregate principal amount equal to the
principal amount of the Global Securities in exchange for such Global
Securities.

      In the event of the occurrence of either of the events specified in this
Section, the Company will promptly make available to the Trustee a reasonable
supply of certificated Securities in definitive, fully registered form without
interest coupons.

      Section 2.7 Replacement Securities. If the holder of a Security claims
that the Security has been lost, destroyed or wrongfully taken or if such
Security is mutilated and is surrendered to the Trustee, the Company shall issue
and the Trustee shall authenticate a replacement Security if the Trustee's and
the Company's requirements are met. If required by the Trustee or the Company,
an indemnity bond must be sufficient in the judgment of both to protect and hold
harmless the Company, the Trustee, any Agent or any authenticating agent from
any loss, liability or expense which any of them may suffer if a Security is
replaced. The Company may charge for its expenses in replacing a Security.

      In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, or is about to be redeemed or purchased
by the Company pursuant to Article III hereof or converted into shares of Common
Stock pursuant to Article V hereof, the Company in its discretion may, instead
of issuing a new Security, pay, redeem, purchase or convert such Security, as
the case may be.

      Every replacement Security is an additional obligation of the Company and
shall be entitled to all the benefits provided under this Indenture equally and
proportionately with all other Securities duly issued hereunder.

      Section 2.8 Outstanding Securities. The Securities outstanding at any time
are all the Securities authenticated by the Trustee except for those canceled by
it, those delivered to it for cancellation, and those described in this Section
as not outstanding, provided, however, that in determining whether the holders
of the requisite principal amount of outstanding Securities are present at a
meeting of holders of Securities for quorum purposes or have consented to or
voted in favor of any request, demand, authorization, direction, notice,
consent, waiver, amendment or modification hereunder, Securities held for the
account of the Company, any of its Subsidiaries or any of its Affiliates shall
be disregarded and deemed not to be outstanding, except that in determining
whether the Trustee shall be protected in making such a determination or relying
upon any such quorum, consent or vote, only Securities which a Responsible
Officer of the Trustee actually knows to be so owned shall be so disregarded.

      If a Security is replaced (including pursuant to Section 2.1(a)), paid or
purchased pursuant to Section 2.7 hereof, it ceases to be outstanding unless the
Trustee receives proof satisfactory to it that the replaced, paid or purchased
Security is held by a bona fide purchaser.

      If Securities are considered paid under Section 4.1 hereof, they cease to
be outstanding and interest on them ceases to accrue.


                                       15

      A Security does not cease to be outstanding because the Company or an
Affiliate of the Company holds the Security.

      Section 2.9 Treasury Securities. In determining whether the Noteholders of
the required principal amount of Securities have concurred in any direction,
waiver or consent, Securities owned by the Company or an Affiliate of the
Company shall be considered as though they are not outstanding, except that for
the purposes of determining whether the Trustee shall be protected in relying on
any such direction, waiver or consent, only Securities which a Responsible
Officer of the Trustee actually knows are so owned shall be so disregarded.

      Section 2.10 Temporary Securities. Until definitive Securities are ready
for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Securities in
exchange for temporary Securities.

      Section 2.11 Cancellation. The Company at any time may deliver Securities
to the Trustee for cancellation. The Registrar, Paying Agent and Conversion
Agent shall forward to the Trustee any Securities surrendered to them for
registration of transfer, redemption, conversion, exchange or payment. The
Trustee shall promptly cancel all Securities surrendered for registration of
transfer, redemption, conversion, exchange, payment, replacement or
cancellation, shall dispose of such canceled Securities in accordance with its
customary procedures (subject to the record retention requirement of the
Exchange Act) and deliver to the Company a certificate of a Responsible Officer
certifying as to such destruction. The Company may not issue new Securities to
replace Securities that it has paid or that have been delivered to the Trustee
for cancellation or that any holder has converted.

      Section 2.12 Transfer of Interests in Global Securities. The registered
holder of a Global Security may grant proxies and otherwise authorize any
person, including Agent Members and persons that may hold interests through
Agent Members, to take any action which a holder is entitled to take under this
Indenture or the Securities.

      Section 2.13 Defaulted Interest. If the Company fails to make a payment of
interest on the Securities, it shall pay such defaulted interest plus any
interest payable on the defaulted interest, in any lawful manner. It may pay
such defaulted interest, plus any such interest payable on it, to the persons
who are Noteholders on a subsequent special record date. The Company shall fix
any such record date and payment date. At least 15 days before any such record
date, the Company shall cause to be mailed to Noteholders a notice that states
the record date, payment date, and amount of such interest to be paid.

                                   ARTICLE III

                            REDEMPTION AND REPURCHASE

      Section 3.1 Notices to Trustee. If the Company elects to redeem Securities
pursuant to the optional redemption provision of Section 3.7 hereof, it shall
notify the Trustee of the


                                       16

redemption date and the principal amount of Securities to be redeemed. The
Company shall give each notice to the Trustee provided for in this Section 3.1
at least 30 days before the redemption date (unless a shorter notice period
shall be satisfactory to the Trustee).

      Section 3.2 Selection of Securities to be Redeemed. If less than all the
Securities are to be redeemed, the Trustee shall select the Securities to be
redeemed in compliance with the requirements of the principal national
securities exchange, if any, on which the Securities are listed, or, if the
Securities are not so listed, on a pro rata basis. The Trustee shall make the
selection not more than 60 days and not less than 20 days before the redemption
date from Securities outstanding not previously called for redemption. The
Trustee may select for redemption portions of the principal of Securities that
have denominations larger than $1,000. Securities and portions of them it
selects shall be in amounts of $1,000 or integral multiples of $1,000.
Provisions of this Indenture that apply to Securities called for redemption also
apply to portions of Securities called for redemption. The Trustee shall notify
the Company promptly of the Securities or portions of Securities to be called
for redemption.

      If any Security selected for partial redemption is converted in part after
such selection, the converted portion of such Security shall be deemed (so far
as may be) to be the portion to be selected for redemption. The Securities (or
portions thereof) so selected shall be deemed duly selected for redemption for
all purposes hereof, notwithstanding that any such Security is converted in
whole or in part before the mailing of the notice of redemption. Upon any
redemption of less than all the Securities, the Company and the Trustee may
treat as outstanding any Securities surrendered for conversion during the period
20 days next preceding the mailing of a notice of redemption and need not treat
as outstanding any Security authenticated and delivered during such period in
exchange for the unconverted portion of any Security converted in part during
such period.

      Section 3.3 Notice of Redemption. At least 30 days but not more than 40
days before a redemption date, the Company shall mail a notice of redemption to
each holder whose Securities are to be redeemed at such holder's registered
address.

      The notice shall identify the Securities to be redeemed (including the
CUSIP numbers) and shall state:

            (a) the redemption date;

            (b) the redemption price;

            (c) if any Security is being redeemed in part, the portion of the
principal amount of such Security to be redeemed and that, after the redemption
date, upon cancellation of such Security, a new Security or Securities in
principal amount equal to the unredeemed portion will be issued in the name of
the holder thereof;

            (d) the name and address of the Paying Agent;

            (e) that Securities called for redemption must be surrendered to the
Paying Agent to collect the redemption price plus accrued interest, if any;


                                       17

            (f) that, unless the Company defaults in making such redemption
payment or the Paying Agent is prohibited from making such payment pursuant to
the terms of this Indenture, interest on Securities called for redemption ceases
to accrue on and after the redemption date; and

            (g) the paragraph of the Securities pursuant to which the Securities
called for redemption are being redeemed.

      Such notice shall also state the current Conversion Price and the date on
which the right to convert such Securities or portions thereof into Common Stock
of the Company will expire.

      At the Company's request, the Trustee shall give notice of redemption in
the Company's name and at its expense.

      Section 3.4 Effect of Notice of Redemption. Once notice of redemption is
mailed, Securities called for redemption become due and payable on the
redemption date at the price set forth in the Security.

      Section 3.5 Deposit of Redemption Price. On or before 10:00 am New York
City time on the redemption date, the Company shall deposit with the Trustee or
with the Paying Agent money sufficient to pay the redemption price of and
accrued interest, if any, up to but not including the redemption date on all
Securities to be redeemed on that date (subject to the right of holders of
record on the relevant record date to receive interest, if any, due on an
interest payment date) unless theretofore converted into Common Stock pursuant
to the provisions hereof. The Trustee or the Paying Agent shall return to the
Company any money not required for that purpose.

      Section 3.6 Securities Redeemed in Part. Upon cancellation of a Security
that is redeemed in part, the Company shall issue and the Trustee shall
authenticate for the holder at the expense of the Company a new Security equal
in principal amount to the unredeemed portion of the Security surrendered.

      Section 3.7 Optional Redemption. The Company may redeem all or any portion
of the Securities, at the times, upon the terms and at the redemption prices set
forth in each of the Securities. Any redemption pursuant to this Section 3.7
shall be made pursuant to the provisions of Section 3.1 through 3.6 hereof.

      Section 3.8 Designated Event Offer.

            (a) In the event that, pursuant to Section 4.7 hereof, the Company
shall commence a Designated Event Offer, the Company shall follow the procedures
in this Section 3.8.

            (b) The Designated Event Offer shall remain open for a period
specified by the Company which shall be no less than 30 calendar days and no
more than 40 calendar days following its commencement on the date of the mailing
of notice in accordance with Section 3.8(e) hereof (the "Commencement Date"),
except to the extent that a longer period is required by applicable law (the
"Tender Period"). Upon the expiration of the Tender Period (the


                                       18

"Designated Event Payment Date"), the Company shall purchase the principal
amount of Securities required to be purchased pursuant to Section 4.7 hereof at
a purchase price equal to 100% of principal thereof, together with accrued and
unpaid interest thereon, if any, plus an amount in cash equal to the sum of the
amount of interest that would have accrued and been payable in respect of the
outstanding principal balance of the Securities that are tendered for redemption
during the Tender Period for the period commencing on the Designated Event
Payment Date through the earlier to occur of (i) the two year anniversary of the
Designated Event Payment Date and (ii) February 26, 2007 (the "Designated Event
Payment").

            (c) If the Designated Event Payment Date is on or after an interest
payment record date and on or before the related interest payment date, any
accrued interest will be paid to the person in whose name a Security is
registered at the close of business on such record date, and no additional
interest will be payable to Noteholders who tender Securities pursuant to the
Designated Event Offer.

            (d) The Company shall provide the Trustee with notice of the
Designated Event Offer at least 10 Business Days before the Commencement Date.

            (e) On or before the Commencement Date, the Company or the Trustee
(upon the request and at the expense of the Company) shall send, by first class
mail, a notice to each of the Noteholders, which shall govern the terms of the
Designated Event Offer and shall state:

                  (i) that the Designated Event Offer is being made pursuant to
this Section 3.8 and Section 4.7 hereof and that all Securities tendered will be
accepted for payment;

                  (ii) the purchase price (as determined in accordance with
Section 4.7 hereof), the length of time the Designated Event Offer will remain
open and the Designated Event Payment Date;

                  (iii) that any Security or portion thereof not tendered for
payment will continue to accrue interest;

                  (iv) that, unless the Company defaults in the payment of the
Designated Event Payment, any Security or portion thereof accepted for payment
pursuant to the Designated Event Offer shall cease to accrue interest after the
Designated Event Payment Date;

                  (v) that Noteholders electing to have a Security or portion
thereof purchased pursuant to any Designated Event Offer will be required to
surrender the Security, with the form entitled "Option of Noteholder To Elect
Purchase" on the reverse of the Security completed, to the Paying Agent at the
address specified in the notice prior to the close of business on the third
Business Day preceding the Designated Event Payment Date;

                  (vi) that Noteholders will be entitled to withdraw their
election if the Paying Agent receives, not later than the close of business on
the second Business Day preceding the Designated Event Payment Date, or such
longer period as may be required by law, a letter or a telegram, telex or
facsimile transmission (receipt of which is confirmed and promptly followed by a
letter) setting forth the name of the Noteholder, the principal amount of the
Security or


                                       19

portion thereof the Noteholder delivered for purchase and a statement that such
Noteholder is withdrawing his election to have the Security or portion thereof
purchased; and

                  (vii) that Noteholders whose Securities are being purchased
only in part will be issued new Securities equal in principal amount to the
unpurchased portion of the Securities surrendered, which unpurchased portion
must be equal to $1,000 in principal amount or an integral multiple thereof.

            In addition, the notice shall contain all instructions and materials
that the Company shall reasonably deem necessary to enable such Noteholders to
tender Securities pursuant to the Designated Event Offer.

            (f) On or prior to 10:00 a.m. New York City time on the Designated
Event Payment Date, the Company shall irrevocably deposit with the Trustee or a
Paying Agent in immediately available funds an amount equal to the Designated
Event Payment to be held for payment in accordance with the terms of this
Section 3.8. On the Designated Event Payment Date, the Company shall, to the
extent lawful, (i) accept for payment the Securities or portions thereof
tendered pursuant to the Designated Event Offer, (ii) deliver or cause to be
delivered to the Trustee Securities so accepted and (iii) deliver to the Trustee
an Officers' Certificate stating such Securities or portions thereof have been
accepted for payment by the Company in accordance with the terms of this Section
3.8. The Paying Agent shall promptly (but in any case not later than ten (10)
calendar days after the Designated Event Payment Date) mail or deliver to each
tendering Noteholder an amount equal to the purchase price of the Securities
tendered by such Noteholder, and the Trustee shall promptly authenticate and
mail or deliver to such Noteholders a new Security equal in principal amount to
any unpurchased portion of the Security surrendered, if any; provided, that each
new Security shall be in a principal amount of $1,000 or an integral multiple
thereof. Any Securities not so accepted shall be promptly mailed or delivered by
or on behalf of the Company to the holder thereof. The Company will publicly
announce the results of the Designated Event Offer on, or as soon as practicable
after, the Designated Event Payment Date.

            (g) The Designated Event Offer shall be made by the Company in
compliance with all applicable provisions of the Exchange Act, and all
applicable tender offer rules promulgated thereunder, and shall include all
instructions and materials that the Company shall reasonably deem necessary to
enable such Noteholders to tender their Securities.

                                   ARTICLE IV

      Section 4.1 Payment of Securities. The Company shall pay the principal of,
premium, if any and interest on the Securities on the dates and in the manner

principal, premium, if any and interest then due and such Paying Agent is not
prohibited from paying such money to the Noteholders on that date pursuant to
the terms of this Indenture. To the extent lawful, the Company shall pay
interest (including post petition interest


                                       20

in any proceeding under any Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace period) at the rate borne by the
Securities, compounded semiannually.

      Section 4.2 SEC Reports. Whether or not required by the rules and
regulations of the SEC, so long as any Securities are outstanding, the Company
will file with the SEC and, if requested, furnish to the Trustee and to the
holders of Securities all quarterly and annual financial information required to
be contained in a filing with the SEC on Forms 10-Q and 10-K, including a
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and, with respect to annual information only, a report thereon by
the Company's certified independent accountants. Delivery of such reports,
information and documents to the Trustee is for informational purposes only and
the Trustee's receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).

      Section 4.3 Compliance Certificate. The Company shall deliver to the
Trustee, within 120 days after the end of each fiscal year of the Company, an
Officers' Certificate stating that a review of the activities of the Company and
its Subsidiaries during the preceding fiscal year has been made under the
supervision of the signing Officers with a view to determining whether the
Company has kept, observed, performed and fulfilled its obligations under, and
complied with the covenants and conditions contained in, this Indenture, and
further stating, as to each such Officer signing such certificate, that to the
best of his or her knowledge, the Company has kept, observed, performed and
fulfilled each and every covenant, and complied with the covenants and
conditions contained in this Indenture and is not in default in the performance
or observance of any of the terms, provisions and conditions hereof (or, if a
Default or Event of Default shall have occurred, describing all such Defaults or
Events of Default of which he or she may have knowledge) and that to the best of
his or her knowledge no event has occurred and remains in existence by reason of
which payments on account of the principal or of interest, if any, on the
Securities are prohibited.

      One of the Officers signing such Officers' Certificate shall be either the
Company's principal executive officer, principal financial officer or principal
accounting officer.

      The Company will, so long as any of the Securities are outstanding,
deliver to the Trustee, forthwith upon becoming aware of:

            (a) any Default, Event of Default or default in the performance of
any covenant, agreement or condition contained in this Indenture; or

            (b) any event of default under any other mortgage, indenture or
instrument described in Section 8.1(e), an Officers' Certificate specifying such
Default, Event of Default or default.

extent that it may lawfully do so) that it will 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 wherever


                                       21

enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not, by resort to any such law, hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer
and permit the execution of every such power as though no such law has been
enacted.

      Section 4.5 Corporate Existence. Subject to Article VII hereof, the
Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate existence and the corporate, partnership or
other existence of each Subsidiary of the Company in accordance with the
respective organizational documents of each Subsidiary and the rights (charter
and statutory), licenses and franchises of the Company and its Subsidiaries;
provided, however, that the Company shall not be required to preserve any such
right, license or franchise, or the corporate, partnership or other existence of
any Subsidiary, if the Board of Directors shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Company and
its Subsidiaries taken as a whole and that the loss thereof is not adverse in
any material respect to the Noteholders. Notwithstanding the foregoing, the
corporate existence of any Subsidiary may also be terminated in connection with
any Board approved corporate restructuring or reorganization.

      Section 4.6 Taxes. The Company shall, and shall cause each of its
Subsidiaries to, pay prior to delinquency all taxes, assessments and
governmental levies, except as contested in good faith and by appropriate
proceedings.

shall have the right, in accordance with this Section 4.7 and Section 3.8
hereof, to require the Company to repurchase all or any part (equal to $1,000 or
an integral multiple thereof) of such holder's Securities pursuant to the terms
of Section 3.8 (the "Designated Event Offer") at a purchase price in cash equal
to 100% of the principal amount thereof, together with accrued and unpaid
interest thereon, if any, to the Designated Event Payment Date, plus an amount
payable in cash equal to the Designated Event Payment.

      (b) Within 30 days following any Designated Event and on or before the
Commencement Date, the Company shall mail to each holder the notice provided by
Section 3.8(e).

      (c) Payment by the Company of the Designated Event Payment upon the
occurrence of a Designated Event is subject to the subordination provisions of
Article VI.

      Section 4.8 Stockholder Rights Plan. In the event that the Company
implements a stockholder rights plan, such rights plan shall provide that upon
conversion of the Securities the holders will receive, in addition to the Common
Stock issuable upon such conversion, the rights issued under such rights plan
(whether or not such rights have separated from the Common Stock at the time of
such conversion), provided that a holder of Securities shall be subject to all
of the terms and conditions of any such rights plan.


                                       22

      Section 4.9 Exchange Limitations. Without the prior written consent of the
holders of Securities representing at least fifty percent (50%) of the then
outstanding principal amount of the Securities, during the period commencing on
the Issuance Date through the date that is 180 days thereafter, the Company
shall not consummate any exchange transaction with its existing security holders
in reliance upon the exemption from registration provided for in Section 3(a)(9)
of the Securities Act or any other exchange of Common Stock for the Existing
Debentures or the Existing Senior Subordinated Notes, provided that nothing in
this Section 4.9 shall prohibit or limit the Company's ability to issue shares
of Common Stock upon conversion of the Existing Debentures or the Existing
Senior Subordinated Notes in accordance with their terms.

      Section 4.10 Use of Proceeds. The Company shall not use the proceeds from
the issuance and sale of the Securities for any purpose other than as set forth
in Section 5.5 of each of the Purchase Agreements dated as of February 20, 2003
by and between the Company and each of the other Persons identified therein as
"Purchasers.".

      Section 4.11 Stockholder Approval. The Company shall use commercially
reasonable best effort to obtain the Stockholder Approval (as defined in Section
5.17(c)) at the Company's next annual meeting of stockholders.

                                    ARTICLE V

                                   CONVERSION

      Section 5.1 Conversion Privilege. A holder of a Security may convert the
principal amount thereof (or any portion thereof that is an integral multiple of
$1,000) into fully paid and nonassessable shares of Common Stock of the Company
at any time prior to the close of business (New York City time) on the date of
the Security's maturity at the Conversion Price then in effect, except that,
with respect to any Security called for redemption, such conversion right shall
terminate at the close of business on the Business Day immediately preceding the
redemption date (unless the Company shall default in making the redemption
payment when it becomes due, in which case the conversion right shall terminate
on the date such default is cured). A Security in respect of which a holder has
delivered an "Option of Noteholder to Elect Purchase" form appearing in Exhibit
A attached hereto exercising the option of such holder to require the Company to
purchase such Security may be converted only if the notice of exercise is
withdrawn as provided in Section 3.8. The number of shares of Common Stock
issuable upon conversion of a Security is determined by dividing the principal
amount of the Security converted by the conversion price in effect on the
Conversion Date (the "Conversion Price").

      The initial Conversion Price is stated in paragraph 10 of the Securities
and is subject to adjustment as provided in this Article V.

      Provisions of this Indenture that apply to conversion of all of a Security
also apply to conversion of a portion of it. A holder of Securities is not
entitled to any rights of a holder of Common Stock (other than as provided in
Section 4.8 hereof) until such holder of Securities has converted such
Securities into Common Stock, and only to the extent that such Securities are
deemed to have been converted into Common Stock under this Article V.


                                       23

      Section 5.2 Conversion Procedure. To convert a Security, a holder must
satisfy the requirements in paragraph 10 of the Securities. The date on which
the holder satisfies all of those requirements is the conversion date (the
"Conversion Date"). As soon as practicable after the Conversion Date, the
Company shall deliver to the holder through the Conversion Agent a certificate
for the number of whole shares of Common Stock issuable upon the conversion and
a check for any fractional share determined pursuant to Section 5.3. Such
certificate shall bear any legends set forth on the converted Security, unless
and to the extent the restrictions contained in such legends no longer apply to
such Common Stock. The person in whose name the certificate is registered shall
become the stockholder of record on the Conversion Date and, as of such date,
such person's rights as a Noteholder shall cease; provided, however, that no
surrender of a Security on any date when the stock transfer books of the Company
shall be closed shall be effective to constitute the person entitled to receive
the shares of Common Stock upon such conversion as the stockholder of record of
such shares of Common Stock on such date, but such surrender shall be effective
to constitute the person entitled to receive such shares of Common Stock as the
stockholder of record thereof for all purposes at the close of business on the
next succeeding day on which such stock transfer books are open; provided
further, however, that such conversion shall be at the Conversion Price in
effect on the date that such Security shall have been surrendered for
conversion, as if the stock transfer books of the Company had not been closed.

      Except for any required payments of Additional Interest or Additional
Voluntary Conversion Interest, no payment or adjustment will be made for accrued
and unpaid interest on a converted Security or for dividends or distributions on
shares of Common Stock issued upon conversion of a Security; provided, however,
that on the Conversion Date, the Company will pay to the holder that has
exercised its conversion right hereunder an amount equal to all accrued but
unpaid interest on the Security surrendered for conversion for the period
through the day prior to the Conversion Date.

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

      Upon surrender of a Security that is converted in part, the Trustee shall
authenticate for the holder a new Security equal in principal amount to the
unconverted portion of the Security surrendered.

      Section 5.3 Fractional Shares. The Company will not issue fractional
shares of Common Stock upon conversion of a Security. In lieu thereof, the
Company will pay an amount in cash based upon the Daily Market Price of the
Common Stock on the trading day prior to the date of conversion.

      Section 5.4 Taxes on Conversion. The issuance of certificates for shares
of Common Stock upon the conversion of any Security shall be made without charge
to the converting Noteholder for such certificates or for any tax in respect of
the issuance of such certificates, and such certificates shall be issued in the
respective names of, or in such names as may be directed by, the holder or
holders of the converted Security; provided, however, that in the event that
certificates for shares of Common Stock are to be issued in a name other than
the name of the


                                       24

holder of the Security converted, such Security, when surrendered for
conversion, shall be accompanied by an instrument of transfer, in form
satisfactory to the Company, duly executed by the registered holder thereof or
his duly authorized attorney; and provided further, however, that the Company
shall not be required to pay any tax which may be payable in respect of any
transfer involved in the issuance and delivery of any such certificates in a
name other than that of the holder of the converted Security, and the Company
shall not be required to issue or deliver such certificates unless or until the
person or persons requesting the issuance 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 or is not applicable.

      Section 5.5 Company to Provide Stock. The Company shall at all times
reserve and keep available, free from preemptive rights, out of its authorized
but unissued Common Stock, solely for the purpose of issuance upon conversion of
Securities as herein provided, a sufficient number of shares of Common Stock to
permit the conversion of all outstanding Securities for shares of Common Stock.
All shares of Common Stock which may be issued upon conversion of the Securities
shall be duly authorized, validly issued, fully paid and nonassessable when so
issued.

      Section 5.6 Adjustment of Conversion Price. The Conversion Price shall be
subject to adjustment from time to time as follows:

            (a) In case the Company shall (1) pay a dividend in shares of Common
Stock to holders of Common Stock, (2) make a distribution in shares of Common
Stock to holders of Common Stock, (3) subdivide its outstanding shares of Common
Stock into a greater number of shares of Common Stock or (4) combine its
outstanding shares of Common Stock into a smaller number of shares of Common
Stock, the Conversion Price in effect immediately prior to such action shall be
adjusted so that the holder of any Security thereafter surrendered for
conversion shall be entitled to receive the number of shares of Common Stock
which he would have owned immediately following such action had such Securities
been converted immediately prior thereto. Any adjustment made pursuant to this
subsection (a) shall become effective immediately after the record date in the
case of a dividend or distribution and shall become effective immediately after
the effective date in the case of a subdivision or combination. In the event of
a reverse stock split of the Common Stock, the Conversion Price shall be subject
to further adjustment as provided in Section 5.6(f) below.

            (b) In case the Company shall issue rights or warrants to
substantially all holders of Common Stock entitling them (for a period
commencing no earlier than the record date for the determination of holders of
Common Stock entitled to receive such rights or warrants and expiring not more
than 45 days after such record date) to subscribe for or purchase shares of
Common Stock (or securities convertible into Common Stock) at a price per share
less than the current market price per share (as determined pursuant to
subsection (g) below) of the Common Stock on such record date, the Conversion
Price shall be adjusted so that the same shall equal the price determined by
multiplying the Conversion Price in effect immediately prior to such record date
by a fraction of which the numerator shall be the number of shares of Common
Stock outstanding on such record date, plus the number of shares of Common Stock
which the aggregate offering price of the offered shares of Common Stock (or the
aggregate conversion price of the convertible securities so offered) would
purchase at such current market price, and of


                                       25

which the denominator shall be the number of shares of Common Stock outstanding
on such record date plus the number of additional shares of Common Stock offered
(or into which the convertible securities so offered are convertible). Such
adjustments shall become effective immediately after such record date.

            (c) In case the Company shall distribute to all holders of Common
Stock shares of any class of Capital Stock of the Company other than Common
Stock, evidences of indebtedness or other assets (other than cash dividends out
of current or retained earnings), or shall distribute to substantially all
holders of Common Stock rights or warrants to subscribe for securities (other
than those securities referred to in subsection (b) above), then in each such
case the Conversion Price shall be adjusted so that the same shall equal the
price determined by multiplying the Conversion Price in effect immediately prior
to the date of such distribution by a fraction of which the numerator shall be
the current market price per share (determined as provided in subsection (f)
below) of the Common Stock on the record date mentioned below less the then fair
market value (as determined by the Board of Directors, whose determination shall
be conclusive evidence of such fair market value and described in a Board
Resolution) of the portion of the assets so distributed or of such subscription
rights or warrants applicable to one share of Common Stock, and of which the
denominator shall be such current market price per share of the Common Stock.
Such adjustment shall become effective immediately after the record date for the
determination of the holders of Common Stock entitled to receive such
distribution. Notwithstanding the foregoing, in the event that the Company shall
distribute rights or warrants to subscribe for additional shares of the
Company's Capital Stock (other than the Common Stock referred to in subsection
(b) above) ("Rights") pro rata to holders of Common Stock, the Company may, in
lieu of making any adjustment pursuant to this Section 5.6, make proper
provision so that each holder of a Security who converts such Security (or any
portion thereof) after the record date for such distribution and prior to the
expiration or redemption of the Rights shall be entitled to receive upon such
conversion, in addition to the shares of Common Stock issuable upon such
conversion (the "Conversion Shares"), a number of Rights to be determined as
follows: (i) if such conversion occurs on or prior to the date for the
distribution to the holders of Rights of separate certificates evidencing such
Rights (the "Distribution Date"), the same number of Rights to which a holder of
a number of shares of Common Stock equal to the number of Conversion Shares is
entitled at the time of such conversion in accordance with the terms and
provisions of and applicable to the Rights; and (ii) if such conversion occurs
after the Distribution Date, the same number of Rights to which a holder of the
number of shares of Common Stock into which the principal amount of the Security
so converted was convertible immediately prior to the Distribution Date would
have been entitled on the Distribution Date in accordance with the terms and
provisions of and applicable to the Rights.

            (d) In case the Company shall, by dividend or otherwise, at any time
distribute to all holders of its Common Stock cash (including any distributions
of cash out of current or retained earnings of the Company but excluding any
cash that is distributed as part of a distribution requiring a Conversion Price
adjustment pursuant to paragraph (c) of this Section) in an aggregate amount
that, together with the sum of (x) the aggregate amount of any other
distributions to all holders of its Common Stock made in cash plus (y) all
Excess Payments, in each case made within the 12 months preceding the date fixed
for determining the stockholders entitled to such distribution (the
"Distribution Record Date") and in respect of which no Conversion Price
adjustment pursuant to paragraphs (c) or (e) of this Section or this


                                       26

paragraph (d) has been made, exceeds 15% of the product of the current market
price per share (determined as provided in paragraph (f) of this Section) of the
Common Stock on the Distribution Record Date times the number of shares of
Common Stock outstanding on the Distribution Record Date (excluding shares held
in the treasury of the Company), the Conversion Price shall be reduced so that
the same shall equal the price determined by multiplying such Conversion Price
in effect immediately prior to the effectiveness of the Conversion Price
reduction contemplated by this paragraph (d) by a fraction of which the
numerator shall be the current market price per share (determined as provided in
paragraph (f) of this Section) of the Common Stock on the Distribution Record
Date less the amount of such cash and other consideration (including any Excess
Payments) so distributed applicable to one share (based on the pro rata portion
of the aggregate amount of such cash and other consideration (including any
Excess Payments), divided by the shares of Common Stock outstanding on the
Distribution Record Date) of Common Stock and the denominator shall be such
current market price per share (determined as provided in paragraph (f) of this
Section) of the Common Stock on the Distribution Record Date, such reduction to
become effective immediately prior to the opening of business on the day
following the Distribution Record Date.

            (e) In case a tender offer or other negotiated transaction made by
the Company or any Subsidiary of the Company for all or any portion of the
Common Stock shall be consummated, if an Excess Payment is made in respect of
such tender offer or other negotiated transaction and the amount of such Excess
Payment, together with the sum of (x) the aggregate amount of all Excess
Payments plus (y) the aggregate amount of all distributions to all holders of
the Common Stock made in cash (specifically including distributions of cash out
of retained earnings), in each case made within the 12 months preceding the date
of payment of such current negotiated transaction consideration or expiration of
such current tender offer, as the case may be (the "Purchase Date"), and as to
which no adjustment pursuant to paragraph (c) or paragraph (d) of this Section
or this paragraph (e) has been made, exceeds 15% of the product of the current
market price per share (determined as provided in paragraph (f) of this Section)
of the Common Stock on the Purchase Date times the number of shares of Common
Stock outstanding (including any tendered shares but excluding any shares held
in the treasury of the Company) on the Purchase Date, the Conversion Price shall
be reduced so that the same shall equal the price determined by multiplying such
Conversion Price in effect immediately prior to the effectiveness of the
Conversion Price reduction contemplated by this paragraph (e) by a fraction of
which the numerator shall be the current market price per share (determined as
provided in paragraph (f) of this Section) of the Common Stock on the Purchase
Date less the amount of such Excess Payments and such cash distributions, if
any, applicable to one share (based on the pro rata portion of the aggregate
amount of such Excess Payments and such cash distributions, divided by the
shares of Common Stock outstanding on the Purchase Date) of Common Stock and the
denominator shall be such current market price per share (determined as provided
in paragraph (f) of this Section) of the Common Stock on the Purchase Date, such
reduction to become effective immediately prior to the opening of business on
the day following the Purchase Date.

            (f) If the Company effects a reverse stock split of the Common Stock
prior to 90 days after the SEC has declared effective the Shelf Registration
Statement, the Conversion Price related to the Securities shall be adjusted
first as provided in Section 5.6(a) above, and then shall be further adjusted on
the 15th day following the expiration of the Pricing Period (as defined


                                       27

below) by multiplying the existing Conversion Price by a fraction, the numerator
of which shall be the VWAP per share of the Common Stock for the period
beginning on the 11th trading day following the effective date of the reverse
stock split and ending on the 30th trading day following the effective date of
the reverse stock split (such period being the "Pricing Period") and the
denominator of which shall be the VWAP per share of the Common Stock for the
five trading day period ending on the earlier of (i) the date that the Company
publicly discloses its intention to effectuate (or consider) such reverse stock
split through a press release, proxy materials or other means or (ii) the date
that the Company publicly discloses that it has received any notice or other
communication from the NYSE to the effect that the Common Stock will be
de-listed.

            (g) The current market price per share of Common Stock on any date
shall be deemed to be the average of the Daily Market Prices for the shorter of
(i) 30 consecutive Business Days ending on the last full trading day on the
exchange or market referred to in determining such Daily Market Prices prior to
the time of determination or (ii) the period commencing on the date next
succeeding the first public announcement of the issuance of such rights or such
warrants or such other distribution or such negotiated transaction through such
last full trading day on the exchange or market referred to in determining such
Daily Market Prices prior to the time of determination.

            (h) In any case in which this Section 5.6 shall require that an
adjustment be made immediately following a record date for an event, the Company
may elect to defer, until such event, issuing to the holder of any Security
converted after such record date the shares of Common Stock and other Capital
Stock of the Company issuable upon such conversion over and above the shares of
Common Stock and other Capital Stock of the Company issuable upon such
conversion only on the basis of the Conversion Price prior to adjustment; and,
in lieu of the shares the issuance of which is so deferred, the Company shall
issue or cause its stock transfer agent to issue due bills or other appropriate
evidence of the right to receive such shares.

      Section 5.7 No Adjustment. No adjustment in the Conversion Price shall be
required until cumulative adjustments amount to 1% or more of the Conversion
Price as last adjusted; provided, however, that any adjustments which by reason
of this Section 5.7 are not required to be made shall be carried forward and
taken into account in any subsequent adjustment. All calculations under this
Article V 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 rights to purchase
Common Stock pursuant to a Company plan for reinvestment of dividends or
interest. No adjustment need be made for a change in the par value or no par
value of the Common Stock.

      Section 5.8 Other Adjustments.

      (a) In the event that, as a result of an adjustment made pursuant to
Section 5.6 above, the holder of any Security thereafter surrendered for
conversion shall become entitled to receive any shares of Capital Stock of the
Company other than shares of its Common Stock, thereafter the Conversion Price
of such other shares so receivable upon conversion of any Securities shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions with respect to Common Stock
contained in this Article V.


                                       28

      (b) In the event that shares of Common Stock are not delivered after the
expiration of any of the rights or warrants referred to in Section 5.6(b) and
Section 5.6(c) hereof, the Conversion Price shall be readjusted to the
Conversion Price which would otherwise be in effect had the adjustment 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.

      Section 5.9 Adjustments for Tax Purposes. The Company may, at its option,
make such reductions in the Conversion Price, in addition to those required by
Section 5.6 above, as it determines to be advisable in order that any stock
dividend, subdivision of shares, distribution of rights to purchase stock or
securities or distribution of securities convertible into or exchangeable for
stock made by the Company to its stockholders will not be taxable to the
recipients thereof.

      Section 5.10 Adjustments by the Company. The Company from time to time
may, to the extent permitted by law, reduce the Conversion Price by any amount
for any period of at least 20 days, in which case the Company shall give at
least 15 days notice of such reduction in accordance with Section 5.11, if the
Board of Directors has made a determination that such reduction would be in the
best interests of the Company, which determination shall be conclusive.

      Section 5.11 Notice of Adjustment. Whenever the Conversion Price is
adjusted, the Company shall promptly mail to Noteholders at the addresses
appearing on the Registrar's books a notice of the adjustment and file with the
Trustee an Officers' Certificate briefly stating the facts requiring the
adjustment and the manner of computing it. The certificate shall be conclusive
evidence of the correctness of such adjustment.

      Section 5.12 Notice of Certain Transactions. In the event that:

            (1) the Company takes any action which would require an adjustment
in the Conversion Price;

            (2) the Company takes any action that would require a supplemental
indenture pursuant to Section 5.13; or

            (3) there is a dissolution or liquidation of the Company;

a holder of a Security may wish to convert such Security into shares of Common
Stock prior to the record date for or the effective date of the transaction so
that he may receive the rights, warrants, securities or assets which a holder of
shares of Common Stock on that date may receive. Therefore, the Company shall
mail to Noteholders at the addresses appearing on the Registrar's books and the
Trustee a notice stating the proposed record or effective date, as the case may
be. The Company shall mail the notice at least 15 days before such date;
however, failure to mail such notice or any defect therein shall not affect the
validity of any transaction referred to in clause (1), (2) or (3) of this
Section 5.12.

      Section 5.13 Effect of Reclassifications, Consolidations, Mergers or Sales
on Conversion Privilege. If any of the following shall occur, namely: (i) any
reclassification or change of outstanding shares of Common Stock issuable upon
conversion of Securities (other than a change in par value,


                                       29

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 or merger to
which the Company is a party other than a merger in which the Company is the
continuing corporation and which does not result in any reclassification of, or
change (other than a change in name, or 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) in, outstanding shares of Common Stock or (iii) any sale or
conveyance of all or substantially all of the property or business of the
Company as an entirety, then the Company, or such successor or purchasing
corporation, as the case may be, shall, as a condition precedent to such
reclassification, change, consolidation, merger, sale or conveyance, execute and
deliver to the Trustee a supplemental indenture in form satisfactory to the
Trustee providing that the holder of each Security then outstanding shall have
the right to convert such Security into the kind and amount of shares of stock
and other securities and property (including cash) receivable upon such
reclassification, change, consolidation, merger, sale or conveyance by a holder
of the number of shares of Common Stock deliverable upon conversion of such
Security immediately prior to such reclassification, change, consolidation,
merger, sale or conveyance. Such supplemental indenture shall provide for
adjustments of the Conversion Price which shall be as nearly equivalent as may
be practicable to the adjustments of the Conversion Price provided for in this
Article V. The foregoing, however, shall not in any way affect the right a
holder of a Security may otherwise have, pursuant to clause (ii) of the last
sentence of subsection (c) of Section 5.6, to receive Rights upon conversion of
a Security. If, in the case of any such consolidation, merger, sale or
conveyance, the stock or other securities and property (including cash)
receivable thereupon by a holder of Common Stock includes shares of stock or
other securities and property of a corporation other than the successor or
purchasing corporation, as the case may be, in such consolidation, merger, sale
or conveyance, then such supplemental indenture shall also be executed by such
other corporation and shall contain such additional provisions to protect the
interests of the holders of the Securities as the Board of Directors of the
Company shall reasonably consider necessary by reason of the foregoing. The
provision of this Section 5.13 shall similarly apply to successive
consolidations, mergers, sales or conveyances.

      In the event the Company shall execute a supplemental indenture pursuant
to this Section 5.13, the Company shall promptly file with the Trustee an
Officers' Certificate briefly stating the reasons therefor, the kind or amount
of shares of stock or securities or property (including cash) receivable by
holders of the Securities upon the conversion of their Securities after any such
reclassification, change, consolidation, merger, sale or conveyance and any
adjustment to be made with respect thereto.

      Section 5.14 Trustee's Disclaimer. The Trustee has no duty to determine
when an adjustment under this Article V should be made, how it should be made or
what such adjustment should be, but may accept as conclusive evidence of the
correctness of any such adjustment, and shall be protected in relying upon the
Officers' Certificate with respect thereto which the Company is obligated to
file with the Trustee pursuant to Section 5.11. The Trustee makes no
representation as to the validity or value of any securities or assets issued
upon conversion of Securities, and the Trustee shall not be responsible for the
Company's failure to comply with any provisions of this Article V.

      The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed
pursuant to Section 5.13, but may accept as conclusive evidence of the
correctness thereof, and shall be protected in relying upon,


                                       30

the Officers' Certificate with respect thereto which the Company is obligated to
file with the Trustee pursuant to Section 5.13.

      Section 5.15 Automatic Conversion by the Company.

            (a) The Company may elect to automatically convert all of the
Securities into Common Stock at the Conversion Price (an "Automatic Conversion")
at any time prior to Maturity if (i) the Daily Market Price of the Company's
Common Stock has exceeded 150% of the Conversion Price for at least 20 Trading
Days during any 30-day Trading Day period (the occurrence of such an event being
referred to herein as an "Automatic Conversion Trigger Event"), (ii) the shares
of Common Stock issuable upon the Automatic Conversion are freely tradable
pursuant to an effective Shelf Registration Statement under the Securities Act,
(iii) the Common Stock is, or shall have been, approved for listing on the NYSE,
the American Stock Exchange (the "Amex") or for quotation on the NASDAQ Stock
Market (the "NASDAQ") prior to the Automatic Conversion Date; and (iv) all
shares of Common Stock which may be issued with respect to the payment of
interest on the Securities will be issued out of the Company's authorized but
unissued Common Stock and will, upon issue, be duly and validly issued and fully
paid and non-assessable and free of any preemptive rights.

            (b) Subject to Section 5.17, in the event that the date that the
Securities will be automatically converted (the "Automatic Conversion Date")
occurs prior to Maturity, the Company will pay Additional Interest (as defined
below) in shares of Common Stock. The shares of Common Stock will be valued at
the VWAP per share of the Company's Common Stock for the five Trading Days
immediately prior to the date that the Company sends to the holders of the
Securities the Automatic Conversion Notice. In addition, on the Automatic
Conversion Date, the Company will pay to each holder an amount equal to all
accrued but unpaid interest on the Securities subject to such Automatic
Conversion for the period through the day prior to the Automatic Conversion
Date. "Additional Interest" shall be equal to the interest that would have
accrued and been payable in respect of the outstanding principal balance of the
Securities subject to such Automatic Conversion had such Securities remained
outstanding for the period commencing on the Automatic Conversion Date through
the earlier to occur of (i) the two year anniversary of the Automatic Conversion
Date and (ii) February 26, 2007.

            (c) Unless the Company shall have theretofore called for redemption
all of the outstanding Securities, the Company or, at the request and expense of
the Company, the Trustee, shall give to all holders of Securities notice (the
"Automatic Conversion Notice") of the Automatic Conversion not more than 30 days
but not less than 15 days prior to the Automatic Conversion Date; in any event,
such notice shall be given, if at all, within 3 Business Days of the occurrence
of an Automatic Conversion Trigger Event. The Company shall also deliver a copy
of the Automatic Conversion Notice to the Trustee.

            Each Automatic Conversion Notice shall state:

                  (i) the Automatic Conversion Date,

                  (ii) whether the Additional Interest, if any, shall be paid by
the Company,


                                       31

                  (iii) the place or places where such Securities are to be
surrendered for conversion and accrued Additional Interest, if any, and

                  (iv) the Conversion Price then in effect.

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

            (d) In the event of an Automatic Conversion, the Company shall issue
and deliver to each holder of Securities as promptly after the Automatic
Conversion Date as practicable in accordance with the provisions of this Article
V:

                  (i) a certificate or certificates for the number of full
shares of Common Stock issuable upon conversion of such holder's Securities and
in connection with the payment of the Additional Interest, if any, due on such
Securities, and

                  (ii) any cash due (x) in respect of any fractional shares of
Common Stock otherwise issuable upon conversion and (y) in connection with the
payment of the Additional Interest, if any, due on such Securities.

            (e) All Securities subject to the Automatic Conversion shall be
delivered to the Trustee to be canceled at the direction of the Trustee, which
shall dispose of the same as provided in Section 2.11 hereof.

      Section 5.16 Voluntary Conversion by Holders.

            (a) Subject to the last sentence of this Section 5.16(a), if a
holder elects to voluntarily convert Securities at any time prior to Maturity,
such holder will receive a payment of additional interest equal to Additional
Interest (as defined in Section 5.15(b)) ("Additional Voluntary Conversion
Interest") in shares of Common Stock, as long as the Company has not previously
mailed an Automatic Conversion Notice. The shares of Common Stock will be valued
at the VWAP per share of the Company's Common Stock for the five Trading Days
immediately prior to the date that the holder has delivered to the Company its
notice of election to convert, in substantially in the form attached to the
Securities (which such notice may be provided via facsimile).

                  (i) Additional Voluntary Conversion Interest shall, at the
election of each holder, be paid in cash in the event any shares of Common Stock
to be issued for the payment of Additional Voluntary Conversion Interest in the
Securities hereunder (i) require registration under any federal securities law
before such shares may be freely transferable without being subject to any
transfer restrictions under the Securities Act upon a voluntary conversion and
if such registration is not completed or does not become effective prior to the
date of such voluntary conversion, and/or (ii) require registration with or
approval of any governmental authority under any state law or any other federal
law before such shares may be validly issued or delivered upon a voluntary
conversion and if such registration is not completed or does not become
effective or such approval is not obtained prior to the date of such voluntary
conversion;


                                       32

                  (ii) The Common Stock is, or shall have been, approved for
listing on the NYSE, Amex or for quotation on NASDAQ prior to the date of the
voluntary conversion; and

                  (iii) All shares of Common Stock which may be issued with
respect to the payment of interest on the Securities will be issued out of the
Company's authorized but unissued Common Stock and, will upon issue, be duly and
validly issued and fully paid and non-assessable and free of any preemptive
rights.

            If all of the conditions set forth in this Section 5.16(a) or
Section 5.17 are not satisfied in accordance with the terms thereof, the
interest required to be paid or duly provided for by the Company pursuant to
this Section shall be paid by the Company only in cash.

            (b) In the event of a voluntary conversion by a holder, the Company
shall issue and deliver a certificate or certificates for the number of full
shares of Common Stock issuable upon conversion of the Securities submitted for
conversion and the Additional Voluntary Conversion Interest, if any, due on such
Securities along with any cash in respect of any fractional shares of Common
Stock otherwise issuable upon conversion or in the event that the Company elects
to pay Additional Voluntary Conversion Interest, if any, in Common Stock instead
of cash, for payment to the holder as promptly after the date of the voluntary
conversion as practicable in accordance with the provisions of this Article V.

            (c) All Securities submitted for voluntary conversion shall be
delivered to the Trustee to be canceled at the direction of the Trustee, which
shall dispose of the same as provided in Section 2.11 hereof.

      Section 5.17 Issuance Limitations.

            (a) The total number of shares of Common Stock issued or issuable as
Additional Interest, Additional Voluntary Conversion Interest or Optional
Redemption Interest (as defined in the Form of Security set forth in Exhibit A
attached hereto) in respect of the Securities (including any shares of capital
stock or rights to acquire shares of capital stock issued by the Company which
are aggregated or integrated with the Common Stock issued or issuable as
Additional Interest, Additional Voluntary Conversion Interest or Optional
Redemption Interest in respect of the Securities for purposes of any such rule
or regulation) shall not exceed the maximum number of shares of Common Stock
which the Company can so issue pursuant to any rule or regulation of the NYSE
(or any other principal United States securities market on which the Common
Stock trades) (the "Maximum Interest Share Amount"), which as of the Issuance
Date shall be 4,311,735 (19.99% of the total shares of Common Stock outstanding
on the Issuance Date, less 23,220,307 shares of Common Stock issuable upon
conversion of the Securities), subject to equitable adjustments from time to
time for stock splits, stock dividends combinations, capital reorganizations and
similar events relating to the Common Stock occurring after the Issuance Date.
The limitation set forth in this Section 5.17(a) shall not apply if the
issuances of Common Stock in lieu of cash are Permitted Issuances (as defined
below) or if the Stockholder Approval has been obtained.


                                       33

            (b) In the event the Company issues the Maximum Interest Share
Amount as Additional Interest, Additional Voluntary Conversion Interest or
Optional Redemption Interest in respect of the Securities prior to the date that
all of the Securities have been converted into shares of Common Stock, any
further payments by the Company of Additional Interest, Additional Voluntary
Conversion Interest or Optional Redemption Interest in respect of the Securities
shall be in cash, provided that the limitation set forth in this Section 5.17(b)
shall not apply if the issuances of Common Stock in lieu of cash are Permitted
Issuances or the Stockholder Approval has been obtained.

            (c) Interest on the Securities (other than Additional Interest,
Additional Voluntary Conversion Interest or Optional Redemption Interest) shall
be paid by the Company in cash unless prior to the issuance of shares of Common
Stock in lieu thereof, the Company (i) is permitted (or not prohibited) by the
applicable rules and regulations of the principal securities market on which the
Common Stock is listed or traded to issue shares of Common Stock as such
interest in respect of the Securities in excess of the Maximum Interest Share
Amount (a "Permitted Issuance") or (ii) has obtained stockholder approval of the
issuance of shares of Common Stock as interest on the Securities in excess of
the Maximum Interest Share Amount in accordance with applicable law and the
rules and regulations of any stock exchange, interdealer quotation system or
other self-regulatory organization with jurisdiction over the Company or any of
its securities (the "Stockholder Approval").

                                   ARTICLE VI

                                  SUBORDINATION

      Section 6.1 Agreement to Subordinate. The Company, for itself and its
successors, and each Noteholder, by his acceptance of Securities, agree that the
payment of the principal of or interest on or any other amounts due on the
Securities is subordinated in right of payment, to the extent and in the manner
stated in this Article VI, to the prior payment in full of all existing and
future Senior Debt.

      Section 6.2 No Payment on Securities if Senior Debt in Default. Anything
in this Indenture to the contrary notwithstanding, no payment on account of
principal of or redemption or repurchase of, interest on or other amounts due on
the Securities, including any payments on a Designated Event Offer, and no
redemption, purchase, or other acquisition of the Securities (including, without
limitation, upon a Designated Event), shall be made by or on behalf of the
Company (i) unless full payment of amounts then due for principal and interest
and of all other amounts then due on all Senior Debt has been made or duly
provided for pursuant to the terms of the instrument governing such Senior Debt,
(ii) if, at the time of such payment, redemption, purchase or other acquisition,
or immediately after giving effect thereto, there shall exist under any Senior
Debt, or any agreement pursuant to which any Senior Debt is issued, any default,
which default shall not have been cured or waived and which default shall have
resulted in the full amount of such Senior Debt being declared due and payable
or (iii) if, at the time of such payment, redemption, purchase or other
acquisition, the Trustee shall have received written notice from a
Representative of the holders of Designated Senior Debt (a "Payment Blockage
Notice") that there exists under such Designated Senior Debt, or any agreement
pursuant to which such Designated Senior Debt is issued, any default, which
default shall not have been


                                       34

cured or waived, permitting the holders thereof to declare any amounts of 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 (unless earlier terminated by notice given to the Trustee by a
Representative of the holders of such Designated Senior Debt) on the earlier of
(a) the date on which such event of default shall have been cured or waived or
(b) 180 days from the receipt of the Payment Blockage Notice. Notwithstanding
the provisions described in the immediately preceding sentence (other than in
clauses (i) and (ii)), unless the holders of such Designated Senior Debt or the
Representative of such holders shall have accelerated the maturity of such
Designated Senior Debt, the Company may resume payments on the Securities after
the end of such 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 Senior Debt during such period.

      In the event that, notwithstanding the provisions of this Section 6.2,
payments are made by or on behalf of the Company in contravention of the
provisions of this Section 6.2, such payments shall be held by the Trustee, any
Paying Agent or the holders, as applicable, in trust for the benefit of, and
shall be paid over to and delivered to, the Representative of the holders of
Senior Debt or the trustee under the indenture or other agreement (if any),
pursuant to which any instruments evidencing any Senior Debt may have been
issued for application to the payment of all Senior Debt ratably according to
the aggregate amounts remaining unpaid to the extent necessary to pay all Senior
Debt in full in accordance with the terms of such Senior Debt, after giving
effect to any concurrent payment or distribution to or for the holders of Senior
Debt.

      The Company shall give prompt written notice to the Trustee and any Paying
Agent of any default or event of default under any Senior Debt or under any
agreement pursuant to which any Senior Debt may have been issued. The Trustee
and the Paying Agent may assume that all payments have been made with respect to
all Senior Debt unless the Trustee or the Paying Agent, as the case may be, has
received written notice that payment has not been made and three (3) Business
Days have expired.

      Section 6.3 Distribution on Acceleration of Securities; Dissolution and
Reorganization; Subrogation of Securities.

            (a) If the Securities are declared due and payable because of the
occurrence of an Event of Default, the Company shall give prompt written notice
to the holders of all Senior Debt or to the trustee(s) for such Senior Debt of
such acceleration. The Company may not pay the principal of, premium, if any, or
interest on or any other amounts due on the Securities until five days after
such holders or trustee(s) of Senior Debt receive such notice and, thereafter,
the Company may pay the principal of or interest on or any other amounts due on
the Securities only if the provisions of this Article VI permit such payment.

            (b) Upon (i) any acceleration of the principal amount due on the
Securities because of an Event of Default or (ii) any distribution of assets of
the Company upon any dissolution, winding up, liquidation or reorganization of
the Company (whether in bankruptcy, insolvency or receivership proceedings or
upon an assignment for the benefit of creditors or any other dissolution,
winding up, liquidation or reorganization of the Company):


                                       35

                  (1) the holders of all Senior Debt shall first be entitled to
receive payment in full of the principal thereof, the interest thereon and any
other amounts due thereon before the holders are entitled to receive payment on
account of the principal of or interest on or any other amounts due on the
Securities;

                  (2) any payment or distribution of assets of the Company of
any kind or character, whether in cash, property or securities (other than
securities of the Company as reorganized or readjusted or securities of the
Company or any other corporation provided for by a plan of reorganization or
readjustment the payment of which is subordinate, at least to the extent
provided in this Article with respect to the Securities, to the payment in full
without diminution or modification by such plan of all Senior Debt), to which
the holders or the Trustee would be entitled except for the provisions of this
Article, shall be paid by the liquidating trustee or agent or other person
making such a payment or distribution, directly to the holders of Senior Debt
(or their representatives(s) or trustee(s) acting on their behalf), ratably
according to the aggregate amounts remaining unpaid on account of the principal
of or interest on and other amounts due on the Senior Debt held or represented
by each, to the extent necessary to make payment in full of all Senior Debt
remaining unpaid, after giving effect to any concurrent payment or distribution
to the holders of such Senior Debt; and

                  (3) in the event that, notwithstanding the foregoing, any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities (other than securities of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment the payment of which is
subordinate, at least to the extent provided in this Article with respect to the
Securities, to the payment in full without diminution or modification by such
plan of Senior Debt), shall be received by the Trustee or the holders before all
Senior Debt is paid in full, such payment or distribution shall be held in trust
for the benefit of, and be paid over to upon request by a holder of the Senior
Debt, the holders of the Senior Debt remaining unpaid (or their representatives)
or trustee(s) acting on their behalf, ratably as aforesaid, for application to
the payment of such Senior Debt until all such Senior Debt shall have been paid
in full, after giving effect to any concurrent payment or distribution to the
holders of such Senior Debt.

            Subject to the payment in full of all Senior Debt, the holders shall
be subrogated to the rights of the holders of Senior Debt to receive payments or
distributions of cash, property or securities of the Company applicable to the
Senior Debt until the principal of, premium, if any, and interest, if any, on
the Securities shall be paid in full and, for purposes of such subrogation, no
such payments or distributions to the holders of Senior Debt of cash, property
or securities which otherwise would have been payable or distributable to
holders shall, as between the Company, its creditors other than the holders of
Senior Debt, and the holders, be deemed to be a payment by the Company to or on
account of the Senior Debt, it being understood that the provisions of this
Article are and are intended solely for the purpose of defining the relative
rights of the holders, on the one hand, and the holders of Senior Debt, on the
other hand.

            Nothing contained in this Article or elsewhere in this Indenture or
in the Securities is intended to or shall (i) impair, as between the Company and
its creditors other than the holders of Senior Debt, the obligation of the
Company, which is absolute and unconditional, to pay to the holders the
principal of, premium, if any, and interest, if any, on the Securities as


                                       36

and when the same shall become due and payable in accordance with the terms of
the Securities, (ii) affect the relative rights of the holders and creditors of
the Company other than holders of Senior Debt or, as between the Company and the
Trustee, the obligations of the Company to the Trustee, or (iii) prevent the
Trustee or the holders from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any,
under this Article of the holders of Senior Debt in respect of cash, property
and securities of the Company received upon the exercise of any such remedy.

            Upon distribution of assets of the Company referred to in this
Article, the Trustee, subject to the provisions of Section 9.1 hereof, and the
holders shall be entitled to rely upon a certificate of the liquidating trustee
or agent or other person making any distribution to the Trustee or to the
holders for the purpose of ascertaining the persons entitled to participate in
such distribution, the holders of the Senior Debt and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article.
The Trustee, however, shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt. Nothing contained in this Article or elsewhere in this
Indenture, or in any of the Securities, shall prevent the good faith application
by the Trustee of any moneys which shall have been deposited with it hereunder,
prior to its receipt of written notice of facts which would prohibit such
application, for the purpose of the payment of or on account of the principal
of, premium, if any, or interest on the Securities unless, prior to the date on
which such application is made by the Trustee, the Trustee shall be charged with
actual notice under Section 6.3(d) hereof of the facts which would prohibit the
making of such application.

            (c) The provisions of this Article shall not be applicable to any
cash, properties or securities received by the Trustee or by any holder that are
received as a holder of Senior Debt and nothing in Section 9.11 hereof or
elsewhere in this indenture shall deprive the Trustee or such holder of any of
its rights as such holder.

            (d) The Company shall give prompt written notice to the Trustee of
any fact known to the Company which would prohibit the making of any payment of
money to or by the Trustee in respect of the Securities pursuant to the
provisions of this Article. The Trustee, subject to the provisions of Section
9.1 hereof, shall be entitled to assume that no such fact exists unless the
Company or any holder of Senior Debt or any trustee therefor has given written
notice thereof to the Trustee. Notwithstanding the provisions of this Article or
any other provisions of this indenture, the Trustee shall not be charged with
knowledge of the existence of any fact which would prohibit the making of any
payment of moneys to or by the Trustee in respect of the Securities pursuant to
the provisions in this Article, unless and until three Business Days after the
Trustee shall have received written notice thereof from the Company or any
holder or holders of Senior Debt or from any trustee therefor; and, prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
Section 9.1 hereof, shall be entitled in all respects conclusively to assume
that no such facts exist; provided that if on a date not less than three
Business Days immediately preceding the date upon which, by the terms hereof,
any such moneys may become payable for any purpose (including, without
limitation, the principal of or interest on any Security), the Trustee shall not
have received with respect to such moneys the notice provided for in this
Section 6.3(d), then anything herein contained to the contrary notwithstanding,
the Trustee shall have full power and authority to receive such moneys and to


                                       37

apply the same to the purpose for which they were received, and shall not be
affected by any notice to the contrary which may be received by it on or after
such prior date.

            The Trustee shall be entitled to conclusively rely on the delivery
to it of a written notice by a person representing himself to be a holder of
Senior Debt (or a trustee on behalf of such holder) to establish that such
notice has been given by a holder of Senior Debt (or a trustee on behalf of any
such holder or holders). In the event that the Trustee determines in good faith
that further evidence is required with respect to the right of any person as a
holder of Senior Debt to participate in any payment or distribution pursuant to
this Article, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Debt held by
such person, the extent to which such person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
person under this Article, and, if such evidence is not furnished, the Trustee
may defer any payment to such person pending judicial determination as to the
right of such person to receive such payment; nor shall the Trustee be charged
with knowledge of the curing or waiving of any default of the character
specified in Section 6.2 hereof or that any event or any condition preventing
any payment in respect of the Securities shall have ceased to exist, unless and
until the Trustee shall have received written notice to such effect.

            (e) The provisions of this Section 6.3 applicable to the Trustee
shall (unless the context requires otherwise) also apply to any Paying Agent for
the Company.

      Section 6.4 Reliance by Senior Debt on Subordination Provisions. Each
holder of any Security by his acceptance thereof acknowledges and agrees that
the foregoing subordination provisions are, and are intended to be, an
inducement and a consideration for each holder of any Senior Debt, whether such
Senior Debt was created or acquired before or after the issuance of the
Securities, to acquire and continue to hold, or to continue to hold, such Senior
Debt, and such holder of Senior Debt shall be deemed conclusively to have relied
on such subordination provisions in acquiring and continuing to hold, or in
continuing to hold, such Senior Debt. Notice of any default in the payment of
any Senior Debt, except as expressly stated in this Article, and notice of
acceptance of the provisions hereof are hereby expressly waived. Except as
otherwise expressly provided herein, no waiver, forbearance or release by any
holder of Senior Debt under such Senior Debt or under this Article shall
constitute a release of any of the obligations or liabilities of the Trustee or
holders of the Securities provided in this Article.

      Section 6.5 No Waiver of Subordination Provisions. Except as otherwise
expressly provided herein, no right of any present or future holder of any
Senior Debt to enforce subordination as herein provided shall at any time in any
way be prejudiced or impaired by any act or failure to act on the part of the
Company or by any act or failure to act, in good faith, by any such holder, or
by any noncompliance by the Company with the terms, provisions and covenants of
this Indenture, regardless of any knowledge thereof any such holder may have or
be otherwise charged with.

      Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Debt may, at any time and from time to time, without the
consent of, or notice to, the Trustee or the holders of the Securities, without
incurring responsibility to the holders of the Securities and without impairing
or releasing the subordination provided in this Article VI or the


                                       38

obligations hereunder of the holders of the Securities to the holders of Senior
Debt, do any one or more of the following: (i) change the manner, place or terms
of payment of, or renew or alter, Senior Debt, or otherwise amend or supplement
in any manner Senior Debt or any instrument evidencing the same or any agreement
under which Senior Debt, is outstanding; (ii) sell, exchange, release or
otherwise dispose of any property pledged, mortgaged or otherwise securing
Senior Debt; (iii) release any person liable in any manner for the collection of
Senior Debt; and (iv) exercise or refrain from exercising any rights against the
Company or any other person.

      Section 6.6 Trustee's Relation to Senior Debt. The Trustee in its
individual capacity shall be entitled to all the rights set forth in this
Article in respect of any Senior Debt at any time held by it, to the same extent
as any holder of Senior Debt, and nothing in Section 9.11 hereof or elsewhere in
this Indenture shall deprive the Trustee of any of its rights as such holder.

      With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations, as are
specifically set forth in this Article, and no implied covenants or obligations
with respect to the holders of Senior Debt shall be read into this Indenture
against the Trustee. The Trustee shall not owe any fiduciary duty to the holders
of Senior Debt but shall have only such obligations to such holders as are
expressly set forth in this Article.

      Each holder of a Security by his acceptance thereof authorizes and directs
the Trustee on his behalf to take such action as may be necessary or appropriate
to effectuate the subordination provided in this Article and appoints the
Trustee his attorney-in-fact for any and all such purposes, including, in the
event of any dissolution, winding up or liquidation or reorganization under any
applicable bankruptcy law of the Company (whether in bankruptcy, insolvency or
receivership proceedings or otherwise), the timely filing of a claim for the
unpaid balance of such holder's Securities in the form required in such
proceedings and the causing of such claim to be approved. If the Trustee does
not file a claim or proof of debt in the form required in such proceedings prior
to 30 days before the expiration of the time to file such claims or proofs, then
any holder or holders of Senior Debt or their representative or representatives
shall have the right to demand, sue for, collect, receive and receipt for the
payments and distributions in respect of the Securities which are required to be
paid or delivered to the holders of Senior Debt as provided in this Article and
to file and prove all claims therefor and to take all such other action in the
name of the holders or otherwise, as such holders of Senior Debt or
representative thereof may determine to be necessary or appropriate for the
enforcement of the provisions of this Article.

      Section 6.7 Other Provisions Subject Hereto. Except as expressly stated in
this Article, notwithstanding anything contained in this Indenture to the
contrary, all the provisions of this Indenture and the Securities are subject to
the provisions of this Article. However, nothing in this Article shall apply to
or adversely affect the claims of, or payment to, the Trustee pursuant to
Section 9.7. Notwithstanding the foregoing, the failure to make a payment on
account of principal of or interest on the Securities by reason of any provision
of this Article VI shall not be construed as preventing the occurrence of an
Event of Default under Section 8.1.

      Section 6.8 Certain Conversions, Interest Payments and Repurchases in
Common Stock Deemed Payment. For the purposes of this Article VI only, (1) the
issuance and delivery


                                       39

of junior securities upon (i) conversion of Securities in accordance with
Article V, (ii) upon the payment of interest in accordance with Section 1 of the
form of Security (iii) upon the payment of Additional Interest in accordance
with Section 5.15 or (iv) upon the payment of Additional Voluntary Conversion
Interest in accordance with Section 5.16, in each case in the manner specified
in such respective Sections, shall not be deemed to constitute a payment or
distribution on account of the principal of (or premium, if any) or interest on
Securities or on account of the purchase or other acquisition of Securities, and
will therefore not be subject to the subordination provisions of this Article
VI, and (2) the payment, issuance or delivery of cash (excluding cash paid for
fractional shares upon conversion of a Security or payment of interest,
Additional Interest or Additional Voluntary Conversion Interest), property or
securities (other than junior securities) upon conversion, payment of interest,
payment of Additional Interest or payment of Additional Voluntary Conversion
Interest shall be deemed to constitute payment on account of the principal of
such Security. For the purposes of this Section, the term "junior securities"
means (a) shares of any stock of any class of the Company and (b) securities of
the Company which are subordinated in right of payment to all Senior Debt 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 Securities
are so subordinated as provided in this Article VI. Nothing contained in this
Article or elsewhere in this Indenture or in the Securities is intended to or
shall impair, as among the Company, its creditors other than holders of Senior
Debt and the holders of the Securities, the right, which is absolute and
unconditional, of the holder of any Security to convert such Security in
accordance with Article V.

                                   ARTICLE VII

                                   SUCCESSORS

      Section 7.1 Merger, Consolidation or Sale of Assets. The Company may not
consolidate or merge with or into any person (whether or not the Company is the
surviving corporation), or sell, assign, transfer, lease, convey or otherwise
dispose of all or substantially all of its properties or assets unless:

            (a) the Company is the surviving corporation or the entity or the
person formed by or surviving any such consolidation or merger (if other than
the Company) or to which such sale, assignment, transfer, lease, conveyance or
other disposition shall have been made is a corporation organized or existing
under the laws of the United States, any state thereof or the District of
Columbia;

            (b) the entity or person formed by or surviving any such
consolidation or merger (if other than the Company) assumes all the Obligations
of the Company, pursuant to a supplemental indenture in a form reasonably
satisfactory to the Trustee, under the Securities and the Indenture;

            (c) such sale, assignment, transfer, lease, conveyance or other
disposition of all or substantially all of the Company's properties or assets
shall be as an entirety or virtually as an entirety to one person and such
person shall have assumed all the Obligations of the Company, pursuant to a
supplemental indenture in a form reasonably satisfactory to the Trustee, under
the Securities and the Indenture;


                                       40

            (d) immediately after such transaction no Default or Event of
Default exists; and

            (e) the Company or such person shall have delivered to the Trustee
an Officers' Certificate and an Opinion of Counsel, each stating that such
transaction and the supplemental indenture comply with the Indenture and that
all conditions precedent in the Indenture relating to such transaction have been
satisfied.

      Section 7.2 Successor Corporation Substituted. Upon any consolidation or
merger, or any sale, assignment, transfer, lease, conveyance or other
disposition of all or substantially all of the assets of the Company in
accordance with Section 7.1 hereof, the successor corporation formed by such
consolidation or into or with which the Company is merged or to which such sale,
assignment, transfer, lease, conveyance or other disposition is made shall
succeed to, and be substituted for and may exercise every right and power of,
the Company under this indenture with the same effect as if such successor
person has been named as the Company herein; provided, however, that the
predecessor Company in the case of a sale, assignment, transfer, lease,
conveyance or other disposition shall not be released from the obligation to pay
the principal of and interest on the Securities.

                                  ARTICLE VIII

                              DEFAULTS AND REMEDIES

      Section 8.1 Events of Default. An "Event of Default" occurs if:

            (a) the Company defaults in the payment of interest on any Security
when the same becomes due and payable, whether or not such payments shall be
prohibited by Article VI, and the Default continues for a period of 30 days
after the date due and payable;

            (b) the Company defaults in the payment of the principal of any
Security when the same becomes due and payable at maturity, upon redemption or
otherwise, whether or not such payment shall be prohibited by Article VI;

            (c) the Company defaults in the payment of (i) the Designated Event
Payment when the same becomes due and payable, whether or not such payment may
be prohibited by Article VI or (ii) any amount that is due and payable to the
Noteholders under the Registration Rights Agreements and such default continues
for a period of five Business Days after the date that any such amount was due
and payable;

            (d) the Company fails to provide notice of any Designated Event in
accordance with Section 4.7;

            (e) the Company fails to observe or perform any other covenant or
agreement contained in this Indenture or the Securities, required by it to be
performed and the Default continues for a period of 60 days after the receipt of
written notice from the Trustee to the Company or from the holders of 25% in
aggregate principal amount of the then outstanding Securities to the Company and
the Trustee stating that such notice is a "Notice of Default";


                                       41

            (f) there is a default under any mortgage, indenture or instrument
under which there may be issued or by which there may be secured or evidenced
any Indebtedness for money borrowed by the Company or any Subsidiary of the
Company (or the payment of which is guaranteed by the Company or any Subsidiary
of the Company), whether such Indebtedness or guarantee now exists or is created
after the Issuance Date, which default (i) is caused by a failure to pay when
due principal of or interest on such Indebtedness within the grace period
provided for in such Indebtedness (which failure continues beyond the longer of
any applicable grace period and 30 days) (a "Payment Default") or (ii) results
in the acceleration of such Indebtedness prior to its express maturity and, in
each case, the principal amount of any such Indebtedness, together with the
principal amount of any other such Indebtedness under which there is a Payment
Default or the maturity of which has been so accelerated, aggregates $10 million
or more;

            (g) a final, non-appealable judgment or final, non-appealable
judgments (other than any judgment as to which a reputable insurance company has
accepted full liability) for the payment of money are entered by a court or
courts of competent jurisdiction against the Company or any Subsidiary of the
Company and remain undischarged for a period (during which execution shall not
be effectively stayed) of 60 days, provided that the aggregate of all such
judgments exceeds $10 million;

            (h) the Company or any Material Subsidiary pursuant to or within the
meaning of any Bankruptcy Law: (i) commences a voluntary case, (ii) consents to
the entry of an order for relief against it in an involuntary case in which it
is the debtor, (iii) consents to the appointment of a Bankruptcy Custodian of it
or for all or substantially all of its property, (iv) makes a general assignment
for the benefit of its creditors, or (v) makes the admission in writing that it
generally is unable to pay its debts as the same become due; or

            (i) a court of competent jurisdiction enters an order or decree
under any Bankruptcy Law that: (i) is for relief against the Company or any
Material Subsidiary of the Company in an involuntary case, (ii) appoints a
Bankruptcy Custodian of the Company or any Material Subsidiary of the Company or
for all or substantially all of its property, and the order or decree remains
unstayed and in effect for 60 days, or (iii) orders the liquidation of the
Company or any Material Subsidiary of the Company, and the order or decree
remains unstayed and in effect for 60 days.

      The term "Bankruptcy Law" means Title 11, U.S. Code or any similar Federal
or state law for the relief of debtors. The term "Bankruptcy Custodian" means
any receiver, trustee, assignee, liquidator or similar official under any
Bankruptcy Law.

      Section 8.2 Acceleration. If an Event of Default (other than an Event of
Default specified in clauses (h) and (i) of Section 8.1 hereof) occurs and is
continuing, the Trustee by notice to the Company, or the Noteholders of at least
25% in principal amount of the then outstanding Securities by notice to the
Company and the Trustee, may declare all the Securities to be due and payable.
Upon such declaration, the principal of, premium, if any, and accrued and unpaid
interest on the Securities shall be due and payable immediately. If an Event of
Default specified in clause (h) or (i) of Section 8.1 hereof occurs, such an
amount shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of


                                       42

the Trustee or any Noteholder. The Noteholders of a majority in aggregate
principal amount of the then outstanding Securities by notice to the Trustee may
rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default have
been cured or waived except nonpayment of principal or interest that has become
due solely because of the acceleration.

      Section 8.3 Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal or interest then due and payable on the Securities or to enforce
the performance of any provision of the Securities or this Indenture.

      The Trustee may maintain a proceeding even if it does not possess any of
the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Noteholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

      Section 8.4 Waiver of Past Defaults. The Noteholders of a majority in
aggregate principal amount of the then outstanding Securities by notice to the
Trustee may waive an existing Default or Event of Default and its consequences
except a continuing Default or Event of Default in the payment of the Designated
Event Payment or the principal of, or interest on, any Security. When a Default
or Event of Default is waived, it is cured and ceases; but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereon.

      Section 8.5 Control by Majority. The Noteholders of a majority in
principal amount of the then outstanding Securities may 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 it. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture, is
unduly prejudicial to the rights of other Noteholders, or would involve the
Trustee in personal liability.

      Section 8.6 Limitation on Suits. A Noteholder may pursue a remedy with
respect to this Indenture or the Securities only if:

            (a) the Noteholder gives to the Trustee notice of a continuing Event
of Default;

            (b) the Noteholders of at least 25% in principal amount of the then
outstanding Securities make a request to the Trustee to pursue the remedy;

            (c) such Noteholder or Noteholders offer to the Trustee indemnity
satisfactory to the Trustee against any loss, liability or expense;

            (d) the Trustee does not comply with the request within 60 days
after receipt of the request and the offer of indemnity; and


                                       43

            (e) during such 60-day period the Noteholders of a majority in
principal amount of the then outstanding Securities do not give the Trustee a
direction inconsistent with the request.

      A Noteholder may not use this Indenture to prejudice the rights of another
Noteholder or to obtain a preference or priority over another Noteholder.

      Section 8.7 Rights of Noteholders to Receive Payment. Notwithstanding any
other provision of this Indenture, the right of any Noteholder of a Security to
receive payment of principal and interest on the Security, on or after the
respective due dates expressed in the Security, or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of the Noteholder made pursuant to this
Section.

      Section 8.8 Collection Suit by Trustee. If an Event of Default specified
in Section 8.1(a) or (b) occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Company
for the whole amount of principal and interest remaining unpaid on the
Securities and interest on overdue principal and interest and such further
amount as shall be sufficient to cover the costs and, to the extent lawful,
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

      Section 8.9 Trustee May File Proofs of Claim. The Trustee may file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee and the Noteholders allowed in any
judicial proceedings relative to the Company, its creditors or its property.
Nothing contained herein shall be deemed to authorize the Trustee to authorize
or consent to or accept or adopt on behalf of any Noteholder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Noteholder thereof, or to authorize the Trustee to vote in
respect of the claim of any Noteholder in any such proceeding.

      Section 8.10 Priorities. If the Trustee collects any money or property
pursuant to this Article, it shall pay out the money or proceeds, in the case of
property, in the following order:

            First: to the Trustee for amounts due under Section 9.7 hereof;

            Second: to the holders of Senior Debt to the extent required by
Article VI;

            Third: to Noteholders for amounts due and unpaid on the Securities
for principal and interest, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Securities for principal and
interest, respectively; and

            Fourth: to the Company.

      Except as otherwise provided in Section 2.12 hereof, the Trustee may fix a
record date and payment date for any payment to Noteholders made pursuant to
this Section.


                                       44

      Section 8.11 Undertaking for Costs. In any suit for the enforcement of any
right or remedy under this Indenture or in any suit against the Trustee for any
action taken or omitted by it as a Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section does not apply to a suit by the
Trustee, a suit by a holder pursuant to Section 8.7 hereof, or a suit by
Noteholders of more than 10% in principal amount of the then outstanding
Securities.

                                   ARTICLE IX

                                     TRUSTEE

      Section 9.1 Duties of Trustee.

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

            (b) Except during the continuance of an Event of Default: (i) the
Trustee need perform only those duties that are specifically set forth in this
Indenture and no others and (ii) in the absence of bad faith on its part, the
Trustee may conclusively rely, as to the truth of the statements and the

furnished to the Trustee and conforming to the requirements of this Indenture.
However, the Trustee shall examine the certificates and opinions to determine
whether or not they conform to the requirements of this Indenture.

            (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that (i) this paragraph does not limit the effect of
paragraph (b) of this Section 9.1; (ii) the Trustee shall not be liable for any
error of judgment made in good faith by a Responsible Officer, unless it is
proved that the Trustee was negligent in ascertaining the pertinent facts and
(iii) the Trustee shall not be liable with respect to any action it takes or
omits to take in good faith in accordance with a direction received by it
pursuant to Section 8.5 hereof.

            (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section 9.1. No
provision of this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of
its duties hereunder, or in the exercise of any of its rights or powers, if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.

            (e) The Trustee may refuse to perform any duty or exercise any right
or power unless it receives indemnity satisfactory to it against any loss,
liability or expense.


                                       45

            (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

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

            (b) Before the Trustee acts or refrains from acting, it (unless
other evidence be herein specifically prescribed) may require an Officers'
Certificate or an Opinion of Counsel, or both. The Trustee shall not be liable
for any action it takes or omits to take in good faith in reliance on such
Officers' Certificate or Opinion of Counsel.

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

it reasonably believes to be authorized or within its rights or powers.

            (e) The Trustee shall not be charged with knowledge of any Event of
Default under subsection (c), (d), (e), (f), (g), (h) or (i) of Section 8.1
unless either (1) a Responsible Officer assigned to its Corporate Trust Services
division shall have actual knowledge thereof, or (2) the Trustee shall have
received notice thereof in accordance with Section 12.2 hereof from the Company
or any holder.

            (f) Any request or direction of the Company mentioned herein shall
be sufficiently evidenced by a Company Request or Company Order and any
resolution of the Board of Directors may be sufficiently evidenced by a Board
Resolution.

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

            (h) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the holders pursuant to this Indenture, unless such holders shall have
offered to the Trustee security or indemnity satisfactory to the Trustee against
the costs, expenses and liabilities which might be incurred by it in compliance
with such request or direction.

            (i) 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, note, other evidence of indebtedness or other paper or document, but
the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may see fit, and, if the Trustee shall
determine to


                                       46

make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney
at the sole cost of the Company and shall incur no liability or additional
liability of any kind by reason of such inquiry or investigation.

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

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

      Section 9.3 Individual Rights of Trustee. The Trustee in its individual or
any other capacity may become the owner or pledgee of Securities and may
otherwise deal with the Company or an Affiliate with the same rights it would
have if it were not Trustee. Any Agent may do the same with like rights.
However, the Trustee is subject to Sections 9.10 and 9.11 hereof.

      Section 9.4 Trustee's Disclaimer. The Trustee makes no representation as
to the validity or adequacy of this Indenture or the Securities, it shall not be
accountable for the Company's use of the proceeds from any Securities
authenticated and delivered by the Trustee in conformity with the provisions of
this Indenture, and it shall not be responsible for any statement of the Company
in the Indenture or any statement in the Securities other than its
authentication.

      Section 9.5 Notice of Defaults. If a Default or Event of Default occurs
and is continuing and if it is actually known to the Trustee, the Trustee shall
mail to Noteholders a notice of the Default or Event of Default within 90 days
after it occurs. Except in the case of a Default or Event of Default in payment
on any Security, the Trustee may withhold the notice if and so long as a
committee of its trust officers in good faith determines that withholding the
notice is in the interests of Noteholders.

      Section 9.6 Reports by Trustee to Noteholders. Within 60 days after the
reporting date stated in Section 12.10, the Trustee shall mail to Noteholders a
brief report dated as of such reporting date that complies with TIA Section
313(a) if and to the extent required by such Section 313(a). The Trustee also
shall comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail
all reports as required by TIA Section 313(c).

      A copy of each report at the time of its mailing to Noteholders shall be
filed with the SEC and each stock exchange on which the Securities are listed.
The Company shall notify the Trustee when the Securities are listed on any stock
exchange and any delisting thereof.

      Section 9.7 Compensation and Indemnity. The Company shall pay to the
Trustee from time to time such compensation for its services hereunder as the
Company and the Trustee shall agree on in writing. The Trustee's compensation
shall not be limited by any law on


                                       47

compensation of a trustee of an express trust. The Company shall reimburse the
Trustee upon request for all reasonable and duly documented disbursements,
expenses and advances incurred or made by it. Such disbursements and expenses
may include the reasonable and duly documented disbursements, compensation and
expenses of the Trustee's agents and counsel.

      The Company shall indemnify the Trustee and any predecessor Trustee and
its officers, directors, employees and all other agents against any loss,
damage, claims, liability or expense, including taxes (other than taxes based
upon, measured by, or determined by the income of the Trustee) incurred by it
except as set forth in the next paragraph. The Trustee shall notify the Company
promptly of any claim (whether asserted by the Company, by any holder or any
other person) for which it may seek indemnity. The Company shall defend the
claim and the Trustee shall cooperate in the defense. The Trustee may have
separate counsel and the Company shall pay the reasonable and duly documented
fees, disbursements and expenses of such counsel. The Company need not pay for
any settlement made without its consent, which consent shall not be unreasonably
withheld.

      The Company need not reimburse any expense or indemnify against any loss
or liability incurred by the Trustee through negligence, bad faith or willful
misconduct.

      To secure the Company's payment obligations in this Section, the Trustee
shall have a lien prior to the Securities on all money or property held or
collected by the Trustee, except money or property held in trust to pay
principal and interest on particular Securities.

      When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 8.1(h) or (i) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

      The provisions of this Section 9.7 shall survive the termination of this
Indenture, and the resignation or removal of the Trustee.

      Section 9.8 Replacement of Trustee. A resignation or removal of the
Trustee and appointment of a successor Trustee shall become effective only upon
the successor Trustee's acceptance of appointment as provided in this Section.

      The Trustee may resign by so notifying the Company. The Noteholders of a
majority in principal amount of the then outstanding Securities may remove the
Trustee by so notifying the Trustee and the Company. The Company may remove the
Trustee if:

            (a) the Trustee fails to comply with Section 9.10 hereof, unless the
Trustee's duty to resign is stayed as provided in TIA Section 310(b);

            (b) the Trustee is adjudged a bankrupt or an insolvent or an order
for relief is entered with respect to the Trustee under any Bankruptcy Law;

            (c) a Bankruptcy Custodian or public officer takes charge of the
Trustee or its property; or

            (d) the Trustee becomes incapable of acting.


                                       48

      If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the
Noteholders of a majority in principal amount of the then outstanding Securities
may appoint a successor Trustee to replace the successor Trustee appointed by
the Company.

      If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Noteholders of at least 10% in principal amount of the then outstanding
Securities may petition any court of competent jurisdiction at the expense of
the Company for the appointment of a successor Trustee.

      If the Trustee fails to comply with Section 9.10 hereof, unless the
Trustee's duty to resign is stayed as provided in TIA Section 310(b), any
Noteholder who has been a bona fide holder of a Security for at least six months
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

      A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company. Thereupon the resignation or removal
of the retiring Trustee shall become effective, the Company shall promptly pay
all amounts due and payable to the retiring Trustee pursuant to Section 9.7
hereof and the successor Trustee shall have all the rights, powers and duties of
the Trustee under this Indenture. The successor Trustee shall mail a notice of
its succession to Noteholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 9.7 hereof. Notwithstanding replacement of the Trustee
pursuant to this Section 9.8, the Company's obligations under Section 9.7 hereof
shall continue for the benefit of the retiring Trustee with respect to expenses
and liabilities incurred by it prior to such replacement.

      Section 9.9 Successor Trustee by Merger, Etc. If the Trustee consolidates,
merges or converts into, or transfers all or substantially all of its corporate
trust business to, another corporation, the successor corporation without any
further act shall be the successor Trustee.

      Section 9.10 Eligibility; Disqualification. This Indenture shall always
have a Trustee who satisfies the requirements of TIA Section 310(a)(1) and (5).
The Trustee, or if the Trustee is a member of a bank holding company system, its
bank holding company, shall always have a combined capital and surplus as stated
in Section 12.10 hereof. The Trustee is subject to TIA Section 310(b).

      Section 9.11 Preferential Collection of Claims Against Company. The
Trustee is subject to TIA Section 311(a), excluding any creditor relationship
listed in TIA Section 311(b). A Trustee who has resigned or been removed shall
be subject to TIA Section 311(a) to the extent indicated therein.

      Section 9.12 Sections Applicable to Registrar, Paying Agent and Conversion
Agent. The term "Trustee" as used in Sections 6.3, 9.1, 9.2, 9.3, 9.4 and 9.7
hereof shall (unless the context requires otherwise) be construed as extending
to and including the Trustee acting in its capacity, if any, as Registrar,
Paying Agent and Conversion Agent.

                                    ARTICLE X

                             DISCHARGE OF INDENTURE

      Section 10.1 Termination of Company's Obligations. This Indenture shall
cease to be of further effect (except that the Company's obligations under
Sections 9.7 and 10.2 hereof shall survive) when all outstanding Securities
theretofore authenticated and issued have been delivered to the Trustee for
cancellation and the Company has paid all sums payable hereunder.

      Thereupon, the Trustee upon request of the Company, shall acknowledge in
writing the discharge of the Company's obligations under this Indenture, except
for those surviving obligations specified above.

      Section 10.2 Repayment to Company. The Trustee and the Paying Agent shall
promptly pay to the Company upon request any excess money or securities held by
them at any time.

      The Trustee and the Paying Agent shall pay to the Company upon request any
money held by them for the payment of principal, premium, if any, or interest,
if any, that remains unclaimed for the period ending on the earlier of 10
Business Days prior to the date such funds would escheat to the State or two
years after the date upon which such payment shall have become due; provided,
however, that the Company, or the Trustee at the request of the Company, shall
have first caused notice of such payment to the Company to be mailed to each
Noteholder entitled thereto no less than 30 days prior to such payment. After
payment to the Company, the Trustee and the Paying Agent shall have no further
liability with respect to such money and Noteholders entitled to the money must
look to the Company for payment as general creditors unless any applicable
abandoned property law designates another person.

                                   ARTICLE XI

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

      Section 11.1 Without Consent of Noteholders. The Company and the Trustee
may amend or supplement this Indenture or the Securities without the consent of

            (f) to make any change that provides any additional rights or
benefits to the holders of Securities.

      An amendment under this Section may not make any change that adversely
affects the rights under Article VI of any holder of Senior Debt then
outstanding unless the holders of such Senior Debt (or any group or
representative thereof authorized to give a consent) consent to such change.

      Section 11.2 With Consent of Noteholders. Subject to Section 8.7 hereof,
the Company and the Trustee may amend or supplement this Indenture or the
Securities with the written consent (including consents obtained in connection
with any tender offer or exchange offer for Securities) of the Noteholders of at
least a majority in principal amount of the then outstanding Securities. Subject
to Sections 8.4 and 8.7 hereof, the Noteholders of a majority in principal
amount of the Securities then outstanding may also by their written consent
(including consents obtained in connection with any tender offer or exchange
offer for Securities) waive any existing Default as provided in Section 8.4 or
waive compliance in a particular instance by the Company with any provision of
this Indenture or the Securities. However, without the consent of each
Noteholder affected, an amendment, supplement or waiver under this Section may
not (with respect to any Securities held by a nonconsenting Noteholder):

            (a) reduce the amount of Securities whose Noteholders must consent
to an amendment, supplement or waiver;

            (b) reduce the rate of or change the time for payment of interest on
any Security;

            (c) reduce the principal of or change the fixed maturity of any
Security;

            (d) make any Security payable in money other than that stated in the
Security;

            (e) make any change in Section 8.4, 8.7 or 11.2 hereof (this
sentence);

            (f) waive a default in the payment of the Designated Event Payment
or the principal of, or interest on, any Security (other than as provided in
Section 8.4);

            (g) waive a redemption payment payable on any Security;

            (h) make any change that adversely affects the right of Noteholders
to convert Securities into Common Stock of the Company; or

            (i) make any change in Articles V or VI hereof that adversely
affects the interests of the Noteholders.

      To secure a consent of the Noteholders under this Section 11.2, it shall
not be necessary for the Noteholders to approve the particular form of any
proposed amendment supplement or waiver, but it shall be sufficient if such
consent approves the substance thereof.


                                       51

      An amendment under this Section may not make any change that adversely
affects the rights under Article VI of any holder of Senior Debt then
outstanding unless the holders of such Senior Debt (or any group or
representative thereof authorized to give a consent) consent to such change.

      After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to Noteholders a notice briefly describing the
amendment or waiver.

      Section 11.3 Compliance with Trust Indenture Act. Every amendment to this
Indenture or the Securities shall be set forth in a supplemental indenture that
complies with the TIA as then in effect.

      Section 11.4 Revocation and Effect of Consents. Until an amendment,
supplement or waiver becomes effective, a consent to it by a Noteholder of a
Security is a continuing consent by the Noteholder and every subsequent
Noteholder of a Security or portion of a Security that evidences the same debt
as the consenting Noteholder's Security, even if notation of the consent is not
made on any Security. However, any such Noteholder or subsequent Noteholder may
revoke the consent as to such Noteholder's Security or portion of a Security if
the Trustee receives the notice of revocation before the date on which the
Trustee receives an Officers' Certificate certifying that the Noteholders of the
requisite principal amount of Securities have consented to the amendment,
supplement or waiver.

      The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Noteholders entitled to consent to any amendment,
supplement or waiver. If a record date is fixed, then notwithstanding the
provisions of the immediately preceding paragraph, those persons who were
Noteholders at such record date (or their duly designated proxies), and only
those persons, shall be entitled to consent to such amendment, supplement or
waiver or to revoke any consent previously given, whether or not such persons
continue to be Noteholders after such record date. No consent shall be valid or
effective for more than 90 days after such record date unless consents from
Noteholders of the principal amount of Securities required hereunder or such
amendment or waiver to be effective shall have also been given and not revoked
within such 90-day period.

      After an amendment, supplement or waiver becomes effective it shall bind
every Noteholder, unless it is of the type described in any of clauses (a)
through (i) of Section 11.2 hereof. In such case, the amendment or waiver shall
bind each Noteholder who has consented to it and every subsequent Noteholder of
a Security or portion of a Security that evidences the same debt as the
consenting Noteholder's Security.

      Section 11.5 Notation on or Exchange of Securities. The Trustee may place
an appropriate notation about an amendment or waiver on any Security thereafter
authenticated. The Company in exchange for all Securities may issue and the
Trustee shall authenticate new Securities that reflect the amendment or waiver.

      Section 11.6 Trustee Protected. The Trustee shall sign all supplemental
indentures, except that the Trustee may, but need not, sign any supplemental
indenture that adversely affects its rights.

Trustee to the other is duly given if in writing and delivered in person or
mailed by first class mail or nationally recognized courier to the other's
address stated in Section 12.10 hereof. The Company or the Trustee by notice to
the other may designate additional or different addresses for subsequent notices
or communications.

      Notice shall be deemed given to the Trustee when received by the Trustee.

      Any notice or communication to a Noteholder shall be mailed by first class
mail or by overnight air courier guaranteeing next day delivery to his address
shown on the register kept by the Registrar. Failure to mail a notice or
communication to a Noteholder or any defect in it shall not affect its
sufficiency with respect to other Noteholders.

      If a notice or communication is mailed in the manner provided above within
the time prescribed, it is duly given, whether or not the addressee receives it.

      If the Company mails a notice or communication to Noteholders, it shall
mail a copy to the Trustee and each Agent at the same time.

      All notices or communications shall be in writing.

      In case by reason of the suspension of regular mail service, or by reason
of any other cause, it shall be impossible to mail any notice as required by the
Indenture, then such method of notification as shall be made with the approval
of the Trustee shall constitute a sufficient mailing of such notice.

      Section 12.3 Communication by Noteholders with Other Noteholders.
Noteholders may communicate pursuant to TIA Section 312(b) with other
Noteholders with respect to their rights under this Indenture or the Securities.

include:

            (a) a statement that the person signing such certificate or

            (b) a brief statement as to the nature and scope of the examination
or investigation upon which the statements or opinions contained in such
certificate or opinion are based;

            (c) a statement that, in the opinion of such person, such person has

express an informed opinion as to whether or not such covenant or condition has
been complied with; and

such condition or covenant has been complied with.

      Section 12.6 Rules by Trustee and Agents. The Trustee may make reasonable
rules for action by, or a meeting of, Noteholders. The Registrar or Paying Agent
may make reasonable rules and set reasonable requirements for its functions.

      Section 12.7 Legal Holidays. A "Legal Holiday" is a Saturday, a Sunday or

be open. If a payment date is a Legal Holiday at a place of payment, payment may
be made at that place on the next succeeding day that is not a Legal Holiday,
and no interest shall accrue for the intervening period. If any other operative
date for purposes of this Indenture shall occur on a Legal Holiday then for all
purposes the next succeeding day that is not a Legal Holiday shall be such
operative date.

stockholder, as such of the Company shall not have any liability for any
obligations of the Company under the Securities or the Indenture or for any

creation. Each Noteholder by accepting a Security waives and releases all such
liability. The waiver and release are part of the consideration for the issue of
the Securities.

when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

      1. Interest. This note is one of a series of the 9.0% Convertible Senior
Subordinated Notes due February 26, 2007 (the "Convertible Notes") issued by
Coeur d'Alene Mines Corporation, an Idaho corporation (the "Company"), pursuant
to an indenture dated as of February 26, 2003 (the "Indenture") between the

of the Indenture.

      In the event that the Company elects to pay interest in the Company's

interest payment date.

      Interest on the Convertible Notes will accrue from the most recent date to
which interest has been paid, or if no interest has been paid, from the date of
issuance. Interest will be computed on the basis of a 360-day year of twelve
30-day months. To the extent lawful, the Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest (without regard to any applicable grace period) at the
rate borne by the Convertible Notes, compounded annually.

      2. Method of Payment. The Company will pay interest on the Convertible
Notes (except defaulted interest) to the persons who are registered holders of
the Convertible Notes entitled to such payments at the close of business on the
record date for the next interest payment date even though Convertible Notes are
canceled after the record date and on or before the interest payment date. The
holder hereof must surrender Convertible Notes to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the
United States that at the time of payment is legal tender for payment of public
and private debts. However, the Company may pay principal and interest by check
payable in such money. It may mail an interest check to a holder's registered
address. Additionally, the Company may, subject to certain conditions, pay
interest (including without limitation, Additional Interest and Additional
Voluntary Conversion Interest) by delivery of shares of Common Stock.

      3. Paying Agent and Registrar. The Trustee will act as Paying Agent,
Registrar and Conversion Agent. The Company may change any Paying Agent,
Registrar, co-registrar or Conversion Agent without prior notice. The Company or
any of its Affiliates may act in any such capacity.

                                      A-5

      4. Indenture. The terms of the Convertible Notes include those stated in
the Indenture (which is incorporated hereby as though fully set forth herein)
and those made part of the Indenture by the Trust Indenture Act of 1939 (15 U.S.
Code Sections 77aaa-77bbbb) as in effect on the date of the Indenture. The
Convertible Notes are subject to, and ratified by, all such terms, certain of
which are summarized hereon, and holders are referred to the Indenture and such
Act for a statement of such terms. The Convertible Notes are unsecured
obligations of the Company limited to (except as otherwise provided in the
Indenture) an aggregate principal amount of $37,185,000 and are subordinated in
right of payment to all existing and future Senior Debt of the Company as
provided in the Indenture. Any holder of this Convertible Note shall be deemed
to have agreed to and be bound by all the terms and conditions contained in the
Indenture applicable to a holder of a Convertible Note. All capitalized terms
herein that are not otherwise defined shall have the meaning ascribed thereto in
the Indenture.

      5. Optional Redemption. The Convertible Notes are not subject to
redemption at the Company's option prior to August 26, 2003. On such date and
thereafter and so long as (i) either (A) the Company has sufficient money on
hand or borrowing availability to effect the proposed redemption or (B) the
Company has put on deposit with the Trustee or with the Paying Agent money
sufficient to effect the redemption, in either case as of the date that the
Company sends the notice of redemption referred to in paragraph 6 below and (ii)
the Common Stock issuable in connection with the payment of the Optional
Redemption Interest referred to below has been registered pursuant to an
effective Shelf Registration Statement under the Securities Act, the Convertible
Notes will be subject to redemption at the option of the Company, in whole or in
part (in any integral multiple of $1,000), upon not less than 30 nor more than
40 days' prior notice by mail at the following redemption price (expressed as a
percentage of the principal amount set forth below):



         DATE                                                                          REDEMPTION PRICE
         -----------------------------------------------------------                   ----------------

                                                                                    
         Beginning on August 26, 2003 and ending on February 25, 2004                  102%

         beginning on February 26, 2004 and ending on February 25, 2007                101%

         February 26, 2007                                                             100%


in each case together with the Optional Redemption Interest (as defined below)
and accrued and unpaid interest up to but not including the redemption date
(subject to the right of holders of record on the relevant record date to
receive interest due on an interest payment date). On or after the redemption
date, interest will cease to accrue on the Convertible Notes, or portion
thereof, called for redemption.

      In the event the Company elects to redeem the Convertible Notes in
accordance with this paragraph 5, the Company will pay Optional Redemption
Interest on the principal amount of the Convertible Notes so redeemed. Subject
to Section 5.17 of the Indenture, Optional Redemption Interest shall be payable
in shares of Common Stock. The shares of Common Stock issuable in payment of any
Optional Redemption Interest will be valued at the VWAP per share of the


                                      A-6

Company's Common Stock for the five Trading Days immediately prior to the date
that the Company sends to the holders of the Convertible Notes the notices of
redemption contemplated by paragraph 6 hereof. "Optional Redemption Interest"
shall be equal to the interest that would have accrued and been payable in
respect of the portion of the principal balance of the Convertible Notes called
for redemption pursuant to this paragraph 5 had such principal portion of the
Convertible Notes remained outstanding for the period commencing on the optional
redemption date through the earlier to occur of (i) the two year anniversary of
the optional redemption date and (ii) February 26, 2007.

      6. Notice of Redemption. Notice of redemption will be mailed at least 30
days but not more than 40 days before the redemption date to each holder of the
Convertible Notes to be redeemed at his address of record. The Convertible Notes
in denominations larger than $1,000 may be redeemed in part but only in integral
multiples of $1,000. In the event of a redemption of less than all of the
Convertible Notes, the Convertible Notes will be chosen for redemption by the
Trustee in accordance with the Indenture. Unless the Company defaults in making
such redemption payment, or the Paying Agent is prohibited from making such
payment pursuant to the Indenture, interest will cease to accrue on the
Convertible Notes or portions of them called for redemption on and after the
redemption date.

      If this Convertible Note is redeemed subsequent to a record date with
respect to any interest payment date specified above and on or prior to such
interest payment date, then any accrued interest payable on such interest
payment date will be paid to the person in whose name this Convertible Note is
registered at the close of business on such record date.

      7. Mandatory Redemption. The Company will not be required to make
mandatory redemption payments with respect to the Convertible Notes. There are
no sinking fund payments with respect to the Convertible Notes.

      8. Repurchase at Option of Holder. If there is a Designated Event, the
Company shall be required to offer to purchase on the Designated Event Payment
Date all outstanding Convertible Notes at a purchase price equal to 100% of the
principal amount thereof on the date of purchase, plus accrued and unpaid
interest to the Designated Event Payment Date, plus an amount payable in cash
equal to the sum of the interest that would have accrued and been payable in
respect of the outstanding principal balance of the Convertible Notes that are
tendered for redemption during the Tender Period following the occurrence of the
Designated Event had such principal balance of the Convertible Notes remained
outstanding for the period commencing on the Designated Event Payment Date
through the earlier to occur of (i) the two year anniversary of the Designated
Event Payment Date and (ii) February 26, 2007. Holders of Convertible Notes that
are subject to such a Designated Event Offer will be mailed a notice of
Designated Event Offer from the Company prior to any related Designated Event
Payment Date and, in accordance with the procedures and terms set forth in the
Indenture, may elect to have such Convertible Notes or portions thereof in
authorized denominations purchased by completing the form entitled "Option of
Holder To Elect Purchase." Holders have the right to withdraw their election by
delivering a written notice of withdrawal to the Paying Agent in accordance with
the terms of the Indenture.


                                      A-7

      9. Subordination. The payment of the principal of, premium, if any,
interest on, or any other amounts due on the Convertible Notes is subordinated
in right of payment to all existing and future Senior Debt of the Company, as
described in the Indenture. Each holder, by accepting a Convertible Note, agrees
to such subordination and authorizes and directs the Trustee on its behalf to
take such action as may be necessary or appropriate to effectuate the
subordination so provided and appoints the Trustee as its attorney-in-fact for
such purpose.

      10. Conversion. The holder of any Convertible Note has the right at any
time prior to the close of business (New York time) on the date of the
Convertible Note's maturity, to convert the principal amount thereof (or any
portion thereof that is an integral multiple of $1,000) into shares of Common
Stock at the initial Conversion Price of $1.6014 per share, subject to
adjustment under certain circumstances as more fully described in Section 5.6 of
the Indenture, except that if a Convertible Note is called for redemption, the
conversion right will terminate at the close of business on the Business Day
immediately preceding the date fixed for redemption.

      To convert a Convertible Note, a holder must (1) complete and sign a
notice of election to convert substantially in the form set forth below (which
such notice may be provided via facsimile), (2) surrender the Convertible Note
to a Conversion Agent, (3) furnish appropriate endorsements or transfer
documents if required by the Registrar or Conversion Agent and (4) pay any
transfer or similar tax, if required. Upon conversion, no adjustment or payment
will be made for interest or dividends (except for any required payment of
Additional Voluntary Conversion Interest); provided, however, that on the date
fixed for conversion, the Company will pay to the holder that has exercised its
conversion rights hereunder an amount equal to all accrued but unpaid interest
on the principal portion of its Convertible Note surrendered for conversion for
the period through the day prior to the date fixed for conversion. The number of
shares of Common Stock issuable upon conversion of a Convertible Note is
determined by dividing the principal amount of the Convertible Note converted by
the Conversion Price in effect on the Conversion Date and then adding any shares
of Common Stock to be delivered in payment of the Additional Voluntary
Conversion Interest. No fractional shares will be issued upon conversion but a
cash adjustment will be made for any fractional interest.

      A Convertible Note in respect of which a holder has delivered an "Option
of Holder to Elect Purchase" form appearing below exercising the option of such
holder to require the Company to purchase such Convertible Note may be converted
only if the notice of option to elect to purchase is withdrawn as provided above
and in accordance with the terms of the Indenture. The above description of
conversion of the Convertible Notes is qualified by reference to, and is subject
in its entirety by, the more complete description thereof contained in the
Indenture.

      11. Automatic Conversion by Company. If at any time (a) the Daily Market
Price of the Company's Common Stock exceeds 150% of the Conversion Price for at
least 20 Trading Days during any 30-day Trading Day period, (b) the shares of
Common Stock issuable upon conversion under this paragraph 11 have been
registered pursuant to an effective Shelf Registration Statement under the
Securities Act, (c) the Common Stock is, or shall have been, approved for
listing on the NYSE, the American Stock Exchange (the "Amex") or for quotation
on the NASDAQ Stock Market (the "NASDAQ") prior to the Automatic Conversion
Date; and (d) all shares of Common Stock which may be issued with respect to the
payment of interest on


                                      A-8

the Securities will be issued out of the Company's authorized but unissued
Common Stock and will, upon issue, be duly and validly issued and fully paid and
non-assessable and free of any preemptive rights, the Company may elect to
automatically convert the Convertible Notes into Common Stock pursuant to
Section 5.15 of the Indenture. Subject to Section 5.17 of the Indenture, in the
event that the date that the Convertible Notes will be automatically converted
occurs on or prior to Maturity, the Company will pay Additional Interest in
Common Stock to the holders. The shares of Common Stock will be valued at the
VWAP per share of the Company's Common Stock for the five Trading Days
immediately prior to the date that the Company sends to the holders of the
Convertible Notes the Automatic Conversion Notice. On the date fixed for
conversion, the Company will pay to each holder an amount equal to all accrued
but unpaid interest on the principal portion of its Convertible Note subject to
the Automatic Conversion Notice for the period through the day prior to the date
fixed for conversion. "Additional Interest" shall be equal to the interest that
would have accrued and been payable in respect of the outstanding principal
balance of the Convertible Notes that are converted hereunder had such principal
balance remained outstanding for the period commencing on the Automatic
Conversion Date through the earlier to occur of (i) the two year anniversary of
the Automatic Conversion Date and (ii) February 26, 2007.

      12. Voluntary Conversion by Holder. If any holder elects to voluntarily
convert its Convertible Notes at any time on or prior to Maturity, such holders
will receive a payment of Additional Voluntary Conversion Interest upon
conversion so long as the Company has not previously mailed an automatic
conversion notice to holders. For purposes of paying the Additional Voluntary
Conversion Interest on the Convertible Notes in Common Stock upon a voluntary
conversion, (a) the provisions of Section 5.17 of the Indenture shall apply and
(b) the shares of Common Stock will be valued at VWAP per share of the Company's
Common Stock for the five Trading Days immediately prior to the date that the
holder has delivered to the Company its notice of election to convert, as
contemplated by clause (1) of the second paragraph of paragraph 10 above.

      13. Denominations, Transfer, Exchange. The Convertible Notes are in
registered form, without coupons, in denominations of $1,000 and integral
multiples of $1,000. The transfer of Convertible Notes may be registered, and
Convertible Notes may be exchanged, as provided in the Indenture. The Registrar
may require a holder, among other things, to furnish appropriate endorsements
and transfer documents and to pay any taxes and fees required by law or
permitted by the Indenture. The Registrar need not exchange or register the
transfer of any Convertible Note or portion of a Convertible Note selected for
redemption (except the unredeemed portion of any Convertible Note being redeemed
in part). Also, the Registrar need not exchange or register the transfer of any
Convertible Note for a period of 15 days before a selection of Convertible Notes
to be redeemed.

      14. Persons Deemed Owners. Except as provided in paragraph 2 of this
Convertible Note, the registered holder of a Convertible Note may be treated as
its owner for all purposes.

      15. Unclaimed Money. If money for the payment of principal or interest
remains unclaimed for the shorter of two years after such payment was due or a
period ending 10 Business Days prior to the date, such funds would escheat to
the State, the Trustee and the Paying Agent shall pay the money back to the
Company at its request. After that, holders of


                                      A-9

Convertible Notes entitled to the money must look to the Company for payment
unless an abandoned property law designates another person and all liability of
the Trustee and such Paying Agent with respect to such money shall cease.

      16. Defaults and Remedies. The Convertible Notes shall have the Events of
Default as set forth in Section 8.1 of the Indenture. Subject to certain
limitations in the Indenture, if an Event of Default occurs and is continuing,
the Trustee by notice to the Company or the holders of at least 25% in aggregate
principal amount of the then outstanding Convertible Notes by notice to the
Company and the Trustee may declare all the Convertible Notes to be due and
payable immediately, except that in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, all unpaid principal and interest
accrued on the Convertible Notes shall become due and payable immediately
without further action or notice. Upon acceleration as described in either of
the preceding sentences, the subordination provisions of the Indenture preclude
any payment being made to holders for at least 5 days except as otherwise
provided in the Indenture and may preclude payment entirely.

      The holders of a majority in principal amount of the Convertible Notes
then outstanding by written notice to the Trustee may rescind an acceleration
and its consequences if the rescission would not conflict with any judgment or
decree and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of the
acceleration. Holders may not enforce the Indenture or the Convertible Notes
except as provided in the Indenture. Subject to certain limitations, holders of
a majority in principal amount of the then outstanding Convertible Notes issued
under the Indenture may direct the Trustee in its exercise of any trust or
power. The Company must furnish compliance certificates to the Trustee annually.
The above description of Events of Default and remedies is qualified by
reference to, and subject in its entirety by, the more complete description
thereof contained in the Indenture.

      17. Amendments, Supplements and Waivers. Subject to certain exceptions,
the Indenture or the Convertible Notes may be amended or supplemented with the
consent of the holders of at least a majority in principal amount of the then
outstanding Convertible Notes (including consents obtained in connection with a
tender offer or exchange offer for Convertible Notes), and any existing default
may be waived with the consent of the holders of a majority in principal amount
of the then outstanding Convertible Notes including consents obtained in
connection with a tender offer or exchange offer for Convertible Notes. Without
the consent of any holder, the Indenture or the Convertible Notes may be
amended, among other things, to cure any ambiguity, defect or inconsistency, to
provide for assumption of the Company's obligations to holders, to make any
change that does not adversely affect the rights of any holder, to qualify the
Indenture under the TIA, and to comply with the requirements of the SEC in order
to maintain the qualification of the Indenture under the TIA.

      18. Trustee Dealings with the Company. The Trustee, in its individual or
any other capacity, may become the owner or pledgee of Convertible Notes and may
otherwise deal with the Company or an Affiliate with the same rights it would
have if it were not Trustee, subject to certain limitations provided for in the
Indenture and in the TIA. Any Agent may do the same with like rights.


                                     A-10

      19. No Recourse Against Others. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Convertible Notes or the Indenture or for
any claim based on, in respect of or by reason of such obligations or their
creation. Each holder, by accepting a Convertible Note, waives and releases all
such liability. The waiver and release are part of the consideration for the
issue of the Convertible Notes.

      20. Governing Law. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN
THE INDENTURE AND THE CONVERTIBLE NOTES WITHOUT REGARD TO CONFLICT OF LAW
PROVISIONS THEREOF.

      21. Authentication. The Convertible Notes shall not be valid until
authenticated by the manual signature of an authorized officer of the Trustee or
an authenticating agent.

      22. Abbreviations. Customary abbreviations may be used in the name of a
holder or an assignee, such as: TEN COM (for tenants in common), TEN ENT (for
tenants by the entireties), JT TEN (for joint tenants with right of survivorship
and not as tenants in common), CUST (for Custodian), and U/G/M/A (for Uniform
Gifts to Minors Act).

      23. Definitions. Capitalized terms not defined in this Convertible Note
have the meaning given to them in the Indenture. The Company will furnish to any
holder of the Convertible Notes upon written request and without charge a copy
of the Indenture. Request may be made to:

Coeur d'Alene Mines Corporation
The Bank of New York

New York, NY 10286

Attention:  Corporate Trust Office - Global Finance Unit

Ladies and Gentlemen:

      This certificate is delivered to request a transfer of $ ______________
principal amount of the 13 3/8% Convertible Senior Subordinated Notes due 2003
(the "Securities") of Coeur d'Alene Mines Corporation (the "Issuer").

      Upon transfer, the Securities would be registered in the name of the new
beneficial owner as follows:

      Name:  ___________________________________

      Address:  ________________________________

      Taxpayer ID Number:  _____________________

      The undersigned represents and warrants to you that:

      1. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act")), and we are acquiring the Securities not with a view to, or
for offer or sale in connection with, any distribution in violation of the
Securities Act. We have such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risk of our investment in
the Securities and invest in or purchase securities similar to the Securities in
the normal course of our business. We and any accounts for which we are acting
are each able to bear the economic risk of our or its investment.

      2. We understand that the Securities have not been registered under the
Securities Act and, unless so registered, may not be sold except as permitted in
the following sentence. We agree on our own behalf and on behalf of any investor
account for which we are purchasing Securities to offer, sell or otherwise
