                            JDA SOFTWARE GROUP, INC.
                           RESTRICTED STOCK AGREEMENT
                                    (KOZIOL)

      JDA Software Group, Inc. has granted to the Participant named in the
Notice of Grant of Restricted Stock (the "GRANT NOTICE") to which this
Restricted Stock Agreement (the "AGREEMENT") is attached an Award consisting of
Shares subject to the terms and conditions set forth in the Grant Notice and
this Agreement. The Award has been granted pursuant to the JDA Software Group,
Inc. 2005 Performance Incentive Plan (the "PLAN"), as amended to the Date of
Grant, the provisions of which are incorporated herein by reference. By signing
the Grant Notice, the Participant: (a) acknowledges receipt of and represents
that the Participant has read and is familiar with the Grant Notice, this
Agreement, the Plan and a prospectus for the Plan in the form most recently
registered with the Securities and Exchange Commission (the "PLAN PROSPECTUS"),
(b) accepts the Award subject to all of the terms and conditions of the Grant
Notice, this Agreement and the Plan and (c) agrees to accept as binding,
conclusive and final all decisions or interpretations of the Committee upon any
questions arising under the Grant Notice, this Agreement or the Plan.

      1.    DEFINITIONS AND CONSTRUCTION.

            1.1 DEFINITIONS. Unless otherwise defined herein, capitalized terms
shall have the meanings assigned to such terms in the Grant Notice or the Plan.

            1.2 CONSTRUCTION. Captions and titles contained herein are for
convenience only and shall not affect the meaning or interpretation of any
provision of this Agreement. Except when otherwise indicated by the context, the
singular shall include the plural and the plural shall include the singular. Use
of the term "or" is not intended to be exclusive, unless the context clearly
requires otherwise.

      2.    ADMINISTRATION.

            All questions of interpretation concerning the Grant Notice and this
Agreement shall be determined by the Committee. All determinations by the
Committee shall be final and binding upon all persons having an interest in the
Award. Any Officer shall have the authority to act on behalf of the Company with
respect to any matter, right, obligation, or election which is the
responsibility of or which is allocated to the Company herein, provided the
Officer has apparent authority with respect to such matter, right, obligation,
or election.

      3.    THE AWARD.

            3.1 GRANT AND ISSUANCE OF SHARES. On the Date of Grant, the
Participant shall acquire and the Company shall issue, subject to the provisions
of this Agreement, a number of Shares equal to the Total Number of Shares set
forth in the Grant Notice. As a condition to the issuance of the Shares, the
Participant shall execute and deliver to the Company along with the Grant Notice
the Assignment Separate from Certificate duly endorsed (with date and number of
shares blank) in the form attached to the Grant Notice.
<PAGE>
            3.2 NO MONETARY PAYMENT REQUIRED. The Participant is not required to
make any monetary payment (other than applicable tax withholding, if any) as a
condition to receiving the Shares, the consideration for which shall be past
services actually rendered and/or future services to be rendered to a
Participating Company or for its benefit. Notwithstanding the foregoing, if
required by applicable state corporate law, the Participant shall furnish
consideration in the form of cash or past services rendered to a Participating
Company or for its benefit having a value not less than the par value of the
Shares issued pursuant to the Award.

            3.3 BENEFICIAL OWNERSHIP OF SHARES; CERTIFICATE REGISTRATION. The
Participant hereby authorizes the Company, in its sole discretion, to deposit
the Shares with the Company's transfer agent, including any successor transfer
agent, to be held in book entry form during the term of the Escrow pursuant to
Section 6. Furthermore, the Participant hereby authorizes the Company, in its
sole discretion, to deposit, following the term of such Escrow, for the benefit
of the Participant with any broker that the Company requires the Participant to
have an account relationship with, any or all Shares which are no longer subject
to such Escrow. Except as provided by the foregoing, a certificate for the
Shares shall be registered in the name of the Participant, or, if applicable, in
the names of the heirs of the Participant.

            3.4 ISSUANCE OF SHARES IN COMPLIANCE WITH LAW. The issuance of the
Shares shall be subject to compliance with all applicable requirements of
federal, state or foreign law with respect to such securities. No Shares shall
be issued hereunder if their issuance would constitute a violation of any
applicable federal, state or foreign securities laws or other law or regulations
or the requirements of any stock exchange or market system upon which the Stock
may then be listed. The inability of the Company to obtain from any regulatory
body having jurisdiction the authority, if any, deemed by the Company's legal
counsel to be necessary to the lawful issuance of any Shares shall relieve the
Company of any liability in respect of the failure to issue such Shares as to
which such requisite authority shall not have been obtained. As a condition to
the issuance of the Shares, the Company may require the Participant to satisfy
any qualifications that may be necessary or appropriate, to evidence compliance
with any applicable law or regulation and to make any representation or warranty
with respect thereto as may be requested by the Company.

      4.    VESTING OF SHARES.

            4.1 NORMAL VESTING. Except as provided in Section 4.2, the Shares
shall vest and become Vested Shares as provided in the Grant Notice.

            4.2 ACCELERATION OF VESTING UPON A CHANGE IN CONTROL. In the event
of a Change in Control, the vesting of the Shares shall be accelerated in full
and the Total Number of Shares shall be deemed Vested Shares effective as of the
date of the Change in Control, provided that the Participant's Service has not
terminated prior to such date.

            4.3 FEDERAL EXCISE TAX UNDER SECTION 4999 OF THE CODE.

            (A) EXCESS PARACHUTE PAYMENT. In the event that any acceleration of
vesting pursuant to this Agreement and any other payment or benefit received or
to be received by the Participant would subject the Participant to any excise
tax pursuant to Section 4999 of the

                                       2
<PAGE>
Code due to the characterization of such acceleration of vesting, payment or
benefit as an excess parachute payment under Section 280G of the Code, the
Participant may elect, in his or her sole discretion, to reduce the amount of
any acceleration of vesting called for under this Agreement in order to avoid
such characterization.

            (B) DETERMINATION BY INDEPENDENT ACCOUNTANTS. To aid the Participant
in making any election called for under Section 4.3(a), upon the occurrence of
any event that might reasonably be anticipated to give rise to the acceleration
of vesting under Section 4.2 (an "EVENT"), the Company shall promptly request a
determination in writing by independent public accountants selected by the
Company (the "ACCOUNTANTS"). Unless the Company and the Participant otherwise
agree in writing, the Accountants shall determine and report to the Company and
the Participant within twenty (20) days of the date of the Event the amount of
such acceleration of vesting, payments and benefits which would produce the
greatest after-tax benefit to the Participant. For the purposes of such
determination, the Accountants may rely on reasonable, good faith
interpretations concerning the application of Sections 280G and 4999 of the
Code. The Company and the Participant shall furnish to the Accountants such
information and documents as the Accountants may reasonably request in order to
make their required determination. The Company shall bear all fees and expenses
the Accountants may reasonably charge in connection with their services
contemplated by this Section.

      5.    COMPANY REACQUISITION RIGHT.

            5.1 GRANT OF COMPANY REACQUISITION RIGHT. Except to the extent
otherwise provided in an employment agreement between a Participating Company
and the Participant which refers to this Award, in the event that (a) the
Participant's Service terminates for any reason or no reason, with or without
Cause, or (b) the Participant, the Participant's legal representative, or other
holder of the Shares, attempts to sell, exchange, transfer, pledge, or otherwise
dispose of (other than pursuant to an Ownership Change Event), including,
without limitation, any transfer to a nominee or agent of the Participant, any
Shares which are not Vested Shares ("UNVESTED SHARES"), the Company shall
automatically reacquire the Unvested Shares, and the Participant shall not be
entitled to any payment therefor (the "COMPANY REACQUISITION RIGHT").

            5.2 OWNERSHIP CHANGE EVENT. Upon the occurrence of an Ownership
Change Event, any and all new, substituted or additional securities or other
property to which the Participant is entitled by reason of the Participant's
ownership of Unvested Shares shall be immediately subject to the Company
Reacquisition Right and included in the terms "Shares," "Stock" and "Unvested
Shares" for all purposes of the Company Reacquisition Right with the same force
and effect as the Unvested Shares immediately prior to the Ownership Change
Event. For purposes of determining the number of Vested Shares following an
Ownership Change Event, credited Service shall include all Service with any
corporation which is a Participating Company at the time the Service is
rendered, whether or not such corporation is a Participating Company both before
and after the Ownership Change Event.

                                       3
<PAGE>
      6.    ESCROW.

            6.1 APPOINTMENT OF AGENT. To ensure that Shares subject to the
Company Reacquisition Right will be available for reacquisition, the Participant
and the Company hereby appoint the Secretary of the Company, or any other person
designated by the Company, as their agent and as attorney-in-fact for the
Participant (the "AGENT") to hold any and all Unvested Shares and to sell,
assign and transfer to the Company any such Unvested Shares reacquired by the
Company pursuant to the Company Reacquisition Right. The Participant understands
that appointment of the Agent is a material inducement to make this Agreement
and that such appointment is coupled with an interest and is irrevocable. The
Agent shall not be personally liable for any act the Agent may do or omit to do
hereunder as escrow agent, agent for the Company, or attorney in fact for the
Participant while acting in good faith and in the exercise of the Agent's own
good judgment, and any act done or omitted by the Agent pursuant to the advice
of the Agent's own attorneys shall be conclusive evidence of such good faith.
The Agent may rely upon any letter, notice or other document executed by any
signature purporting to be genuine and may resign at any time.

            6.2 ESTABLISHMENT OF ESCROW. The Participant authorizes the Company
to deposit the Unvested Shares with the Company's transfer agent to be held in
book entry form, as provided in Section 3.3, and the Participant agrees to
deliver to and deposit with the Agent each certificate, if any, evidencing the
Shares and an Assignment Separate from Certificate with respect to such book
entry shares and each such certificate duly endorsed (with date and number of
Shares blank) in the form attached to the Grant Notice, to be held by the Agent
under the terms and conditions of this Section 6 (the "ESCROW"). Upon the
occurrence of an Ownership Change Event or a change, as described in Section 8,
in the character or amount of any outstanding stock of the corporation the stock
of which is subject to the provisions of this Agreement, any and all new,
substituted or additional securities or other property to which the Participant
is entitled by reason of his or her ownership of the Shares that remain,
following such Ownership Change Event or change described in Section 8, subject
to the Company Reacquisition Right shall be immediately subject to the Escrow to
the same extent as the Shares immediately before such event. The Company shall
bear the expenses of the Escrow.

            6.3 DELIVERY OF SHARES TO PARTICIPANT. The Escrow shall continue
with respect to any Shares for so long as such Shares remain subject to the
Company Reacquisition Right. Upon termination of the Reacquisition Right with
respect to Shares, the Company shall so notify the Agent and direct the Agent to
deliver such number of Shares to the Participant. As soon as practicable after
receipt of such notice, the Agent shall cause to be delivered to the Participant
the Shares specified by such notice, and the Escrow shall terminate with respect
to such Shares.

      7.    TAX MATTERS.

            7.1 TAX WITHHOLDING.

            (A) IN GENERAL. At the time the Grant Notice is executed, or at any
time thereafter as requested by a Participating Company, the Participant hereby
authorizes withholding from payroll and any other amounts payable to the
Participant, and otherwise agrees

                                       4
<PAGE>
to make adequate provision for, any sums required to satisfy the federal, state,
local and foreign tax withholding obligations of the Participating Company, if
any, which arise in connection with the Award, including, without limitation,
obligations arising upon (a) the transfer of Shares to the Participant, (b) the
lapsing of any restriction with respect to any Shares, (c) the filing of an
election to recognize tax liability, or (d) the transfer by the Participant of
any Shares. The Company shall have no obligation to deliver the Shares or to
release any Shares from the Escrow established pursuant to Section 6 until the
tax withholding obligations of the Participating Company have been satisfied by
the Participant.

            (B) WITHHOLDING IN SHARES. Unless otherwise determined by the
Company, in its sole discretion, the Company satisfy all of a Participating
Company's tax withholding obligations (except with respect to any fractional
share) by withholding a number of whole Vested Shares otherwise deliverable to
the Participant or by requiring the Participant to tender to the Company a
number of whole Vested Shares or vested shares acquired otherwise than pursuant
to the Award having, in any such case, a Fair Market Value, as determined by the
Company as of the date on which the tax withholding obligations arise, not in
excess of the amount of such tax withholding obligations determined by the
applicable minimum statutory withholding rates. The Company is hereby authorized
to satisfy the tax withholding obligations, if any, remaining following the
procedure described in this Section 7.1(b) by withholding from payroll and any
other amounts payable to the Participant.

            7.2 ELECTION UNDER SECTION 83(b) OF THE CODE.

            (a) The Participant understands that Section 83 of the Code taxes as
ordinary income the difference between the amount paid for the Shares, if
anything, and the fair market value of the Shares as of the date on which the
Shares are "substantially vested," within the meaning of Section 83. In this
context, "substantially vested" means that the right of the Company to reacquire
the Shares pursuant to the Company Reacquisition Right has lapsed. The
Participant understands that he or she may elect to have his or her taxable
income determined at the time he or she acquires the Shares rather than when and
as the Company Reacquisition Right lapses by filing an election under Section
83(b) of the Code with the Internal Revenue Service no later than thirty (30)
days after the date of acquisition of the Shares. The Participant understands
that failure to make a timely filing under Section 83(b) will result in his or
her recognition of ordinary income, as the Company Reacquisition Right lapses,
on the difference between the purchase price, if anything, and the fair market
value of the Shares at the time such restrictions lapse. The Participant further
understands, however, that if Shares with respect to which an election under
Section 83(b) has been made are forfeited to the Company pursuant to its Company
Reacquisition Right, such forfeiture will be treated as a sale on which there is
realized a loss equal to the excess (if any) of the amount paid (if any) by the
Participant for the forfeited Shares over the amount realized (if any) upon
their forfeiture. If the Participant has paid nothing for the forfeited Shares
and has received no payment upon their forfeiture, the Participant understands
that he or she will be unable to recognize any loss on the forfeiture of the
Shares even though the Participant incurred a tax liability by making an
election under Section 83(b).

            (b) The Participant understands that he or she should consult with
his or her tax advisor regarding the advisability of filing with the Internal
Revenue Service an election under Section 83(b) of the Code, which must be filed
no later than thirty (30) days after

                                       5
<PAGE>
the date of the acquisition of the Shares pursuant to this Agreement. Failure to
file an election under Section 83(b), if appropriate, may result in adverse tax
consequences to the Participant. The Participant acknowledges that he or she has
been advised to consult with a tax advisor regarding the tax consequences to the
Participant of the acquisition of Shares hereunder. ANY ELECTION UNDER SECTION
83(b) THE PARTICIPANT WISHES TO MAKE MUST BE FILED NO LATER THAN 30 DAYS AFTER
THE DATE ON WHICH THE PARTICIPANT ACQUIRES THE SHARES. THIS TIME PERIOD CANNOT
BE EXTENDED. THE PARTICIPANT ACKNOWLEDGES THAT TIMELY FILING OF A SECTION 83(b)
ELECTION IS THE PARTICIPANT'S SOLE RESPONSIBILITY, EVEN IF THE PARTICIPANT
REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO FILE SUCH ELECTION ON HIS OR HER
BEHALF.

            (c) The Participant will notify the Company in writing if the
Participant files an election pursuant to Section 83(b) of the Code. The Company
intends, in the event it does not receive from the Participant evidence of such
filing, to claim a tax deduction for any amount which would otherwise be taxable
to the Participant in the absence of such an election.

      8.    ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE.

            Subject to any required action by the stockholders of the Company,
in the event of any change in the Stock effected without receipt of
consideration by the Company, whether through merger, consolidation,
reorganization, reincorporation, recapitalization, reclassification, stock
dividend, stock split, reverse stock split, split-up, split-off, spin-off,
combination of shares, exchange of shares, or similar change in the capital
structure of the Company, or in the event of payment of a dividend or
distribution to the stockholders of the Company in a form other than Stock
(excepting normal cash dividends) that has a material effect on the Fair Market
Value of shares of Stock, appropriate adjustments shall be made in the number
and kind of shares subject to the Award, in order to prevent dilution or
enlargement of the Participant's rights under the Award. For purposes of the
foregoing, conversion of any convertible securities of the Company shall not be
treated as "effected without receipt of consideration by the Company." Any
fractional share resulting from an adjustment pursuant to this Section shall be
rounded down to the nearest whole number. Such adjustments shall be determined
by the Committee, and its determination shall be final, binding and conclusive.

      9.    RIGHTS AS A STOCKHOLDER, DIRECTOR, EMPLOYEE OR CONSULTANT.

            The Participant shall have no rights as a stockholder with respect
to any Shares subject to the Award until the date of the issuance of the Shares
(as evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company). No adjustment shall be made for
dividends, distributions or other rights for which the record date is prior to
the date the Shares are issued, except as provided in Section 8. Subject the
provisions of this Agreement, the Participant shall exercise all rights and
privileges of a stockholder of the Company with respect to Shares deposited in
the Escrow pursuant to Section 6. If the Participant is an Employee, the
Participant understands and acknowledges that, except as otherwise provided in a
separate, written employment agreement between a Participating Company and the
Participant, the Participant's employment is "at will" and is for no specified
term. Nothing in

                                       6
<PAGE>
this Agreement shall confer upon the Participant any right to continue in the
Service of a Participating Company or interfere in any way with any right of the
Participating Company Group to terminate the Participant's Service at any time.

      10.   LEGENDS.

            The Company may at any time place legends referencing the Company
Reacquisition Right and any applicable federal, state or foreign securities law
restrictions on all certificates representing the Shares. The Participant shall,
at the request of the Company, promptly present to the Company any and all
certificates representing the Shares in the possession of the Participant in
order to carry out the provisions of this Section. Unless otherwise specified by
the Company, legends placed on such certificates may include, but shall not be
limited to, the following:

      "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
      RESTRICTIONS SET FORTH IN AN AGREEMENT BETWEEN THIS CORPORATION AND THE
      REGISTERED HOLDER, OR HIS PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON
      FILE AT THE PRINCIPAL OFFICE OF THIS CORPORATION."

      11.   TRANSFERS IN VIOLATION OF AGREEMENT.

            No Shares may be sold, exchanged, transferred, assigned, pledged,
hypothecated or otherwise disposed of, including by operation of law, in any
manner which violates any of the provisions of this Agreement and, except
pursuant to an Ownership Change Event, until the date on which such shares
become Vested Shares, and any such attempted disposition shall be void. The
Company shall not be required (a) to transfer on its books any Shares which will
have been transferred in violation of any of the provisions set forth in this
Agreement or (b) to treat as owner of such Shares or to accord the right to vote
as such owner or to pay dividends to any transferee to whom such Shares will
have been so transferred. In order to enforce its rights under this Section, the
Company shall be authorized to give a stop transfer instruction with respect to
the Shares to the Company's transfer agent.

      12.   MISCELLANEOUS PROVISIONS.

            12.1 TERMINATION OR AMENDMENT. The Committee may terminate or amend
the Plan or this Agreement at any time; provided, however, that no such
termination or amendment may adversely affect the Participant's rights under
this Agreement without the consent of the Participant unless such termination or
amendment is necessary to comply with applicable law or government regulation.
No amendment or addition to this Agreement shall be effective unless in writing.

            12.2 NONTRANSFERABILITY OF THE AWARD. The right to acquire Shares
pursuant to the Award shall not be subject in any manner to anticipation,
alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or
garnishment by creditors of the Participant or the Participant's beneficiary,
except transfer by will or by the laws of descent and

                                       7
<PAGE>
distribution. All rights with respect to the Award shall be exercisable during
the Participant's lifetime only by the Participant or the Participant's guardian
or legal representative.

            12.3 FURTHER INSTRUMENTS. The parties hereto agree to execute such
further instruments and to take such further action as may reasonably be
necessary to carry out the intent of this Agreement.

            12.4 BINDING EFFECT. This Agreement shall inure to the benefit of
the successors and assigns of the Company and, subject to the restrictions on
transfer set forth herein, be binding upon the Participant and the Participant's
heirs, executors, administrators, successors and assigns.

            12.5 DELIVERY OF DOCUMENTS AND NOTICES. Any document relating to

that the Participant will be provided with a paper copy of any documents if the
attempted electronic delivery of such documents fails. Similarly, the
Participant understands that the Participant must provide the Company or any
designated third party administrator with a paper copy of any documents if the
attempted electronic delivery of such documents fails. The Participant may
revoke his or her consent to the electronic delivery of documents described in
Section 12.5(a) or may change the electronic mail address to which such

such revoked consent or revised e-mail address by telephone, postal service or

residents entered into and to be performed entirely within the State of Arizona.

participants in the Depositary, duly executed by the Company and authenticated
by the Trustee as hereinafter provided. The aggregate principal amount of any
Global Security may from time to time be increased or decreased by adjustments
made on the records of the Trustee and the Depositary or its nominee as
hereinafter provided.

                                                                              11

<PAGE>

          (b) Book-Entry Provisions. This Section 2.01(b) shall apply only to a
Global Security deposited with or on behalf of the Depositary.

          The Company shall execute and the Trustee shall, in accordance with
this Section 2.01(b) and the written order of the Company, authenticate and
deliver initially one or more Global Securities that (i) shall be registered in
the name of Cede & Co. or other nominee of such Depositary and (ii) shall be
delivered by the Trustee to such Depositary or pursuant to such Depositary's
instructions or held by the Trustee as custodian for the Depositary pursuant to

          Agent Members shall have no rights under this Indenture with respect
to any Global Security held on their behalf by the Depositary or by the Trustee
as the custodian of the Depositary or under such Global Security, and the
Depositary may be treated by the Company, the Trustee and any agent of the
Company or the Trustee as the absolute owner of such Global Security for all
purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent
the Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Depositary or impair, as between the Depositary and its Agent Members, the

the rights of a holder of a beneficial interest in any Global Security.

("Definitive Securities"). Definitive Securities will bear the Restricted
Securities Legend or Affiliate Securities Legend set forth on Exhibit A unless

been (i) issued to an Affiliate or (ii) transferred to an Affiliate of the
Company within two years after the original issuance date of the Security, as
evidenced by a notation on the Assignment Form for such transfer or in the
representation letter delivered in respect thereof, for so long as such Security

Company was an owner of such Security, in each case, bear the Affiliate
Securities Legend set forth in Exhibit A hereto, unless otherwise agreed by the
Company (with written notice thereof to the Trustee).

Company, the Trustee shall authenticate Convertible Subordinated Notes for

Company to authenticate Convertible Subordinated Notes. An authenticating agent
may authenticate Convertible Subordinated Notes whenever the Trustee may do so.

require each Paying Agent (other than the Trustee, who hereby so agrees), to
agree in writing that the Paying Agent will hold in trust for the benefit of
holders of the Convertible Subordinated Notes or the Trustee all money held by
the Paying Agent for the payment of principal or interest (including Liquidated
Damages) on the Convertible Subordinated Notes, and will notify the Trustee of
any default by the Company in respect of 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. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or a Subsidiary of the Company) shall
have no further liability for the money. If the Company or a Subsidiary of the
Company acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the holders of the Convertible Subordinated Notes all
money held by it as Paying Agent.

     SECTION 2.05. Holder Lists. The Trustee shall preserve in as current a form
as is reasonably practicable the most recent list available to it of the names
and addresses of holders of Convertible Subordinated Notes and shall otherwise
comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company
shall furnish to the Trustee at least seven Business Days before each Interest
Payment Date, and as the Trustee may request in writing within fifteen (15) days
after receipt by the Company of any such request (or such lesser time as the
Trustee may reasonably request in order to enable it to timely provide any
notice to be provided by it hereunder), a list in such form and as of such date
as the Trustee may reasonably require of the names and addresses of holders of
Convertible Subordinated Notes.

     SECTION 2.06. Transfer and Exchange. NO CONVERTIBLE SUBORDINATED NOTES OR
SHARES OF COMMON STOCK ISSUED UPON CONVERSION OF CONVERTIBLE SUBORDINATED NOTES
MAY BE TRANSFERRED OR EXCHANGED DURING THE PERIOD FROM THE ISSUE DATE UNTIL
NOVEMBER 18, 2006; PROVIDED, HOWEVER, THAT A HOLDER OF CONVERTIBLE SUBORDINATED
NOTES OR SHARES OF COMMON STOCK ISSUED UPON CONVERSION OF CONVERTIBLE
SUBORDINATED NOTES MAY TRANSFER SUCH SECURITIES TO AN AFFILIATED ENTITY,
PROVIDED THAT SUCH AFFILIATED ENTITY AGREES TO BE BOUND BY THE TRANSFER
PROVISIONS OF THIS INDENTURE AND THE INVESTORS RIGHTS AGREEMENT. When
Convertible Subordinated Notes 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 Convertible Subordinated Notes for 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

                                                                              14

exchanges, the Company shall issue and the Trustee shall authenticate
Convertible Subordinated Notes at the Registrar's request, bearing registration
numbers not contemporaneously outstanding. No service charge shall be made to a
holder 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 other governmental charge payable upon
exchanges pursuant to Sections 2.10, 3.07, 9.05 or 12.02.

          The Company or the Registrar shall not be required (i) to issue,
register the transfer of or exchange Convertible Subordinated Notes during a
period beginning at the opening of business fifteen (15) days before the day of
any selection of Convertible Subordinated Notes for redemption under Section
3.03 and ending at the close of business on the day of selection, (ii) to
register the transfer or exchange of any Convertible Subordinated Note so
selected for redemption in whole or in part, except the unredeemed portion of
any Convertible Subordinated Note being redeemed in part or (iii) to register
the transfer of any Convertible Subordinated Notes surrendered for repurchase
pursuant to Section 4.06.

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

          (a) Notwithstanding any provision to the contrary herein, so long as a
Global Security remains outstanding and is held by or on behalf of the
Depositary, transfers of a Global Security, in whole or in part, or of any
beneficial interest therein, shall only be made in accordance with Sections
2.01(b) and 2.10 and this Section 2.06(a); provided, however, that beneficial
interests in a Global Security may be transferred to Persons who take delivery
thereof in the form of a beneficial interest in the Global Security in
accordance with the transfer restrictions set forth in the Restricted Securities
Legend.

          Except for transfers or exchanges made in accordance with paragraphs
(i) through (iv) of this Section 2.06(a) and Section 2.10, transfers of a Global
Security shall be limited to transfers of such Global Security in whole, but not
in part, to nominees of the Depositary or to a successor of the Depositary or
such successor's nominee.

               (i) Global Security To Definitive Security. If an owner of a
     beneficial interest in a Global Security deposited with the Depositary or
     with the Trustee as custodian for the Depositary wishes at any time to
     transfer its interest in such Global Security to a Person who is required
     to take delivery thereof in the form of a Definitive Security, such owner
     may, subject to the rules and procedures of the Depositary, cause the
     exchange of such interest for one or more Definitive Securities of any
     authorized denomination or denominations and of the same aggregate
     principal amount. Upon receipt by the Registrar of

                                                                              15

<PAGE>

     (1) instructions from the Depositary directing the Trustee to authenticate
     and deliver one or more Definitive Securities of the same aggregate
     principal amount as the beneficial interest in the Global Security to be
     exchanged, such instructions to contain the name or names of the designated
     transferee or transferees, the authorized denomination or denominations of
     the Definitive Securities to be so issued and appropriate delivery
     instructions, and (2) such certifications or other information and, in the
     case of transfers pursuant to Rule 144 under the Securities Act, legal
     opinions as the Company may reasonably require to confirm that such
     transfer is being made pursuant to an exemption from, or in a transaction
     not subject to, the registration requirements of the Securities Act, then
     the Registrar will instruct the Depositary to reduce or cause to be reduced
     such Global Security by the aggregate principal amount of the beneficial
     interest therein to be exchanged and to debit or cause to be debited from
     the account of the Person making such transfer the beneficial interest in
     the Global Security that is being transferred, and concurrently with such
     reduction and debit the Company shall execute, and the Trustee shall
     authenticate and deliver, one or more Definitive Securities of the same
     aggregate principal amount in accordance with the instructions referred to
     above.

               (ii) Definitive Security to Definitive Security. If a holder of a
     Definitive Security wishes at any time to transfer such Definitive Security
     (or portion thereof) to a Person who is required to take delivery thereof
     in the form of a Definitive Security, such holder may, subject to the
     restrictions on transfer set forth herein and in such Definitive Security,
     cause the transfer of such Definitive Security (or any portion thereof in a
     principal amount equal to an authorized denomination) to such transferee.
     Upon receipt by the Registrar of (1) such Definitive Security, duly
     endorsed as provided herein, (2) instructions from such holder directing
     the Trustee to authenticate and deliver one or more Definitive Securities
     of the same aggregate principal amount as the Definitive Security (or
     portion thereof) to be transferred, such instructions to contain the name
     or names of the designated transferee or transferees, the authorized
     denomination or denominations of the Definitive Securities to be so issued
     and appropriate delivery instructions, and (3) such certifications or other
     information and, in the case of transfers pursuant to Rule 144 under the
     Securities Act, legal opinions as the Company may reasonably require to
     confirm that such transfer is being made pursuant to an exemption from, or
     in a transaction not subject to, the registration requirements of the
     Securities Act, then the Registrar, shall cancel or cause to be canceled
     such Definitive Security and concurrently therewith, the Company shall
     execute, and the Trustee shall authenticate and deliver, one or more
     Definitive Securities in the appropriate aggregate principal amount, in
     accordance with the instructions referred to above and, if only a portion
     of a Definitive Security is transferred as aforesaid, concurrently
     therewith Company shall execute and the Trustee shall authenticate and
     deliver to the transferor a Definitive Security in a principal amount equal
     to the principal amount which has not been transferred. A holder of a
     Definitive Security may at any time exchange such Definitive Security

                                                                              16

<PAGE>

     for one or more Definitive Securities of other authorized denominations and
     in the same aggregate principal amount and registered in the same name by
     delivering such Definitive Security, duly endorsed as provided herein, to
     the Trustee together with instructions directing the Trustee to
     authenticate and deliver one or more Definitive Securities in the same
     aggregate principal amount and registered in the same name as the
     Definitive Security to be exchanged, and the Registrar thereupon shall
     cancel or caused to be canceled such Definitive Security and concurrently
     therewith the Company shall execute and Trustee shall authenticate and
     deliver, one or more Definitive Securities in the same aggregate principal
     amount and registered in the same name as the Definitive Security being
     exchanged.

               (iii) Definitive Security to Global Security. If a holder of a
     Definitive Security wishes at any time to transfer such Definitive Security
     (or portion thereof) to a Person who is not required to take delivery
     thereof in the form of a Definitive Security, such holder shall, subject to
     the restrictions on transfer set forth herein and in such Definitive
     Security and the rules of the Depositary cause the exchange of such
     Definitive Security for a beneficial interest in the Global Security. Upon
     receipt by the Registrar of (1) such Definitive Security, duly endorsed as
     provided herein, (2) instructions from such holder directing the Trustee to
     increase the aggregate principal amount of the Global Security deposited
     with the Depository or with the Trustee as custodian for the Depository by
     the same aggregate principal amount at maturity as the Definitive Security
     to be exchanged, such instructions to contain the name or names of a member
     of, or participant in, the Depository that is designated as the transferee,
     the account of such member or participant and other appropriate delivery
     instructions, (3) the assignment form on the back of the Definitive
     Security completed in full, and (4) such certifications or other
     information and, in the case of transfers pursuant to Rule 144 under the
     Securities Act, legal opinions as the Company may reasonably require to
     confirm that such transfer is being made pursuant to an exemption from, or
     in a transaction not subject to, the registration requirements of the
     Securities Act, then the Trustee shall cancel or cause to be canceled such
     Definitive Security and concurrently therewith shall increase the aggregate
     principal amount of the Global Security by the same aggregate principal
     amount as the Definitive Security canceled.

               (iv) Other Exchanges. In the event that a Global Security is
     exchanged for Convertible Subordinated Notes in definitive registered form
     pursuant to Section 2.10 prior to the effectiveness of a Shelf Registration
     Statement with respect to such Convertible Subordinated Notes, such
     Convertible Subordinated Notes may be exchanged only in accordance with
     such procedures as are substantially consistent with the provisions of
     clauses (ii) and (iii) above.

          (b) Except with a transfer or sale of Securities made pursuant to the
Shelf Registration Statement contemplated by and in accordance with the terms of
the Investors Rights Agreement, if Convertible Subordinated Notes are issued
upon the registration of

                                                                              17

<PAGE>

transfer, exchange or replacement of Convertible Subordinated Notes bearing an
Affiliate Securities Legend or a Restricted Securities Legend, as the case may
be, or if a request is made to remove such an Affiliate Securities Legend or a
Restrictive Securities Legend, as the case may be, on Convertible Subordinated
Notes, the Convertible Subordinated Notes so issued shall bear the Affiliate
Securities Legend or the Restricted Securities Legend, as the case may be,
unless there is delivered to the Company such satisfactory evidence, which, in
the case of a transfer made pursuant to Rule 144 under the Securities Act, may
include an opinion of counsel given in accordance with the laws in the State of
New York, as may be reasonably required by the Company, that neither the legend
nor the restrictions on transfer set forth therein are required to ensure that
transfers thereof comply with the provisions of the U.S. federal securities
laws. Upon provision to the Company of such satisfactory evidence, the Trustee,
at the written direction of the Company, shall authenticate and deliver
Convertible Subordinated Notes that do not bear the legend. The Company shall
not otherwise be entitled to require the delivery of a legal opinion in
connection with any transfer or exchange of Securities.

          (c) Neither the Trustee nor any Agent shall have any responsibility
for any actions taken or not taken by the Depositary.

          (d) The Trustee shall have no obligation or duty to monitor, determine
or inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Convertible Subordinated Notes (including any transfers between or among
Depositary's participants or beneficial owners of interests in any Global
Security) other than to require delivery of such certificates and other
documentation as is expressly required by, and to do so if and when expressly
required by, the terms of this Indenture and to examine the same to determine
substantial compliance as to form with the express requirements hereof.

     SECTION 2.07. Replacement Convertible Subordinated Notes. If the holder of
a Convertible Subordinated Note claims that the Convertible Subordinated Note
has been lost, destroyed or wrongfully taken, the Company shall issue and the
Trustee shall authenticate a replacement Convertible Subordinated Note if the
Trustee's requirements are met. If required by the Trustee or the Company as a
condition of receiving a replacement Convertible Subordinated Note, the holder
of a Convertible Subordinated Note must provide a certificate of loss and an
indemnity and/or an indemnity bond sufficient, in the judgment of both the
Company and the Trustee, to fully protect the Company, the Trustee, any Agent
and any authenticating agent from any loss, liability, cost or expense which any
of them may suffer or incur if the Convertible Subordinated Note is replaced.
The Company and the Trustee may charge the relevant holder for their expenses in
replacing any Convertible Subordinated Note.

          The Trustee or any authenticating agent may authenticate any such
substituted Convertible Subordinated Note, and deliver the same upon the receipt
of such security or indemnity as the Trustee, the Company and, if applicable,
such authenticating agent may require. Upon the issuance of any substituted
Convertible Subordinated Note, the Company may require the payment of a sum
sufficient to cover any tax or other

                                                                              18

<PAGE>

governmental charge that may be imposed in relation thereto and any other
expenses connected therewith. In case any Convertible Subordinated Note which
has matured or is about to mature, or has been called for redemption pursuant to
Article III, submitted for repurchase pursuant to Section 4.06 or is about to be
converted into Common Stock pursuant to Article XII, shall become mutilated or
be destroyed, lost or stolen, the Company may, instead of issuing a substitute
Convertible Subordinated Note, pay or authorize the payment of or convert or
authorize the conversion of the same (without surrender thereof except in the
case of a mutilated Convertible Subordinated Note), as the case may be, if the
applicant for such payment or conversion shall furnish to the Company, to the
Trustee and, if applicable, to the authenticating agent such security or
indemnity as may be required by them to save each of them harmless for any loss,
liability, cost or expense caused by or connected with such substitution, and,
in case of destruction, loss or theft, evidence satisfactory to the Company, the
Trustee and, if applicable, any paying agent or conversion agent of the
destruction, loss or theft of such Convertible Subordinated Note and of the
ownership thereof.

          Every replacement Convertible Subordinated Note 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 Convertible
Subordinated Notes duly issued, authenticated and delivered hereunder.

     SECTION 2.08. Outstanding Convertible Subordinated Notes. The Convertible
Subordinated Notes outstanding at any time are all the Convertible Subordinated
Notes properly authenticated by the Trustee except for those canceled by the
Trustee, those delivered to it for cancellation, and those described in this
Section as not outstanding.

          If a Convertible Subordinated Note is replaced pursuant to Section
2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory
to it that the replaced Convertible Subordinated Note is held by a bona fide
purchaser.

          If Convertible Subordinated Notes are considered paid under Section
4.01 or converted under Article XII, they cease to be outstanding and interest
(including Liquidated Damages, if any) on them ceases to accrue.

          Subject to Section 2.09 hereof, a Convertible Subordinated Note does
not cease to be outstanding because the Company or an Affiliate of the Company
holds the Convertible Subordinated Note.

     SECTION 2.09. When Treasury Convertible Subordinated Notes Disregarded. In
determining whether the holders of the required principal amount of Convertible
Subordinated Notes have concurred in any direction, waiver or consent,
Convertible Subordinated Notes 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 Convertible Subordinated Notes which
the Trustee knows are so owned shall be so disregarded; provided however, that
this Section 2.09 shall not apply to any

                                                                              19

<PAGE>

applicable Convertible Subordinated Notes owned by a holder that is an Affiliate
of the Company and is also an Affiliated Entity from the Issue Date until the
applicable Convertible Subordinated Notes are first transferred to a holder that
is not an Affiliated Entity.

     SECTION 2.10. Temporary Convertible Subordinated Notes.

          (a) Until definitive Convertible Subordinated Notes are ready for
delivery, the Company may prepare and the Trustee shall authenticate temporary
Convertible Subordinated Notes. Temporary Convertible Subordinated Notes shall
be substantially in the form of definitive Convertible Subordinated Notes but
may have variations that the Company considers appropriate for temporary
Convertible Subordinated Notes and shall be reasonably acceptable to the
Trustee. Without unreasonable delay, the Company shall prepare and the Trustee
shall authenticate definitive Convertible Subordinated Notes in exchange for
temporary Convertible Subordinated Notes.

          (b) Except for transfers made in accordance with Section 2.06(a), a
Global Security deposited with the Depositary or with the Trustee as custodian
for the Depositary pursuant to Section 2.01 shall be transferred to the
beneficial owners thereof in the form of certificated Convertible Subordinated
Notes in definitive form only if such transfer complies with Section 2.06 and
(i) the Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for such Global Security or if at any time such
Depositary ceases to be a "clearing agency" registered under the Exchange Act
and a successor Depositary is not appointed by the Company within 90 days of
such notice, or (ii) an Event of Default has occurred and is continuing.

          (c) Any Global Security or interest thereon that is transferable to
the beneficial owners thereof in the form of certificated Convertible
Subordinated Notes in definitive form shall, if held by the Depository, be
surrendered by the Depositary to the Trustee, without charge, and the Trustee
shall authenticate and deliver, upon such transfer of each portion of such
Global Security, an equal aggregate principal amount of Convertible Subordinated
Notes of authorized denominations in the form of certificated Convertible
Subordinated Notes in definitive form. Any portion of a Global Security
transferred pursuant to this Section shall be executed, authenticated and
delivered only in denominations of $1,000 and any integral multiple thereof and
registered in such names as the Depositary shall direct. Any Convertible
Subordinated Notes in the form of certificated Convertible Subordinated Notes in
definitive form delivered in exchange for an interest in the Global Security
shall, except as otherwise provided by Section 2.06(b), bear the Restricted
Securities Legend set forth in Exhibit A hereto.

          (d) Prior to any transfer pursuant to Section 2.10(b), 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 Convertible Subordinated Notes.

                                                                              20

<PAGE>

          (e) The Company will make available to the Trustee a reasonable supply
of certificated Convertible Subordinated Notes in definitive form without
interest coupons.

     SECTION 2.11. Cancellation. The Company at any time may deliver Convertible
Subordinated Notes to the Trustee for cancellation. The Registrar and Paying
Agent shall forward to the Trustee any Convertible Subordinated Notes
surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else may cancel Convertible Subordinated Notes surrendered
for registration of transfer, exchange, payment, replacement, conversion,
redemption, repurchase or cancellation. Upon written instructions of the
Company, the Trustee shall destroy and dispose of canceled Convertible
Subordinated Notes as the Company directs and, after such destruction, shall
deliver a certificate of destruction to the Company. The Company may not issue
new Convertible Subordinated Notes to replace Convertible Subordinated Notes
that it has paid, redeemed or repurchased or that have been delivered to the
Trustee for cancellation or that any holder has (i) converted pursuant to
Article XII hereof, (ii) submitted for redemption pursuant to Article III hereof
or (iii) submitted for repurchase pursuant to Section 4.06 hereof (unless
revoked).

     SECTION 2.12. Defaulted Interest. If the Company fails to make a payment of
interest on the Convertible Subordinated Notes, it shall pay such defaulted
interest plus, to the extent lawful, any interest payable on the defaulted
interest. It may pay such defaulted interest, plus any such interest payable on
it, to the Persons who are holders of Convertible Subordinated Notes on a
subsequent special record date. The Company shall fix any such special record
date and payment date. At least 15 days before any such special record date, the
Company shall mail to holders of the Convertible Subordinated Notes a notice
that states the special record date, payment date and amount of such interest to
be paid.

     SECTION 2.13. CUSIP Number. The Company in issuing the Convertible
Subordinated Notes may use a "CUSIP" number, and if so, such CUSIP number shall
be included in notices of redemption, repurchase or exchange as a convenience to
holders of Convertible Subordinated Notes; provided, however, that any such
notice may state that no representation is made as to the correctness or
accuracy of the CUSIP number printed in the notice or on the Convertible
Subordinated Notes and that reliance may be placed only on the other
identification numbers printed on the Convertible Subordinated Notes. The
Company will promptly notify the Trustee of any change in the CUSIP number.

                                   ARTICLE III

                                   REDEMPTION

     SECTION 3.01. Optional Redemption. The Company may redeem all or any
portion of the Convertible Subordinated Notes upon the terms and at the
Redemption Prices set forth in each of the Convertible Subordinated Notes. Any
redemption shall be made pursuant to Paragraph 5 of the Convertible Subordinated
Notes and this Article III.

                                                                              21

<PAGE>

     SECTION 3.02. Notices to Trustee. If the Company elects to redeem
Convertible Subordinated Notes pursuant to the optional redemption provisions of
paragraph 5 of the Convertible Subordinated Notes, it shall furnish to the
Trustee, at least 30 (35 if less than all of the then outstanding Convertible
Subordinated Notes are to be redeemed or if the Company requests the Trustee to
give notice of redemption pursuant to Section 3.04) days but not more than 60
days before a Redemption Date (unless a shorter period shall be satisfactory to
the Trustee), an Officers' Certificate setting forth (i) the Section of this
Indenture pursuant to which the redemption shall occur, (ii) the Redemption
Date, (iii) the principal amount of Convertible Subordinated Notes (if less than
all) to be redeemed, (iv) the Redemption Price and (v) the CUSIP number of the
Convertible Subordinated Notes being redeemed.

     SECTION 3.03. Selection of Convertible Subordinated Notes To Be Redeemed.
If less than all the Convertible Subordinated Notes are to be redeemed, the
Trustee shall select the Convertible Subordinated Notes to be redeemed by a
method that complies with the requirements of the principal national securities
exchange, if any, on which the Convertible Subordinated Notes are listed or
quoted or, if the Convertible Subordinated Notes are not so listed, on a pro
rata basis by lot or by any other method that the Trustee considers fair and
appropriate. The Trustee shall make the selection not more than 60 days and not
less than 30 days before the Redemption Date from Convertible Subordinated Notes
outstanding and not previously called for redemption. The Trustee may select for
redemption a portion of the principal of any Convertible Subordinated Notes that
has a denomination larger than $1,000. Convertible Subordinated Notes and
portions thereof will be redeemed in the amount of $1,000 or integral multiples
of $1,000.

          Provisions of this Indenture that apply to Convertible Subordinated
Notes called for redemption also apply to portions of Convertible Subordinated
Notes called for redemption. The Trustee shall notify the Company promptly of
the Convertible Subordinated Notes or portions of Convertible Subordinated Notes
to be called for redemption.

          If any Convertible Subordinated Note selected for partial redemption
is converted in part after such selection, the converted portion of such
Convertible Subordinated Note shall be deemed (so far as may be) to be the
portion to be selected for redemption. The Convertible Subordinated Notes (or
portion thereof) so selected shall be deemed duly selected for redemption for
all purposes hereof, notwithstanding that any such Convertible Subordinated Note
is converted in whole or in part before the mailing of the notice of redemption.
Upon any redemption of less than all the Convertible Subordinated Notes, the
Company and the Trustee may treat as outstanding any Convertible Subordinated
Notes surrendered for conversion during the period of 15 days next preceding the
mailing of a notice of redemption and need not treat as outstanding any
Convertible Subordinated Note authenticated and delivered during such period in
exchange for the unconverted portion of any Convertible Subordinated Note
converted in part during such period.

                                                                              22

<PAGE>

     SECTION 3.04. Notice of Redemption. At least 30 days but not more than 60
days before a Redemption Date, the Company shall mail by first class mail a
notice of redemption to each holder whose Convertible Subordinated Notes are to
be redeemed.

          The notice shall identify the Convertible Subordinated Notes to be
redeemed and shall state:

                    (1) the Redemption Date;

                    (2) the Redemption Price;

                    (3) if any Convertible Subordinated Note is being redeemed
     in part, the portion of the principal amount of such Convertible
     Subordinated Note to be redeemed and that, after the Redemption Date, upon
     surrender of such Convertible Subordinated Note, a new Convertible
     Subordinated Note or Convertible Subordinated Notes in principal amount
     equal to the unredeemed portion will be issued in the name of the holder
     thereof;

                    (4) that Convertible Subordinated Notes called for
     redemption must be surrendered to the Paying Agent to collect the
     Redemption Price;

                    (5) that interest and Liquidated Damages, if applicable, on
     Convertible Subordinated Notes called for redemption and for which funds
     have been set apart for payment, ceases to accrue on and after the
     Redemption Date (unless the Company defaults in the payment of the
     Redemption Price or the Paying Agent is prohibited from making such payment
     pursuant to the terms of this Indenture);

                    (6) the paragraph of the Convertible Subordinated Notes
     pursuant to which the Convertible Subordinated Notes called for redemption
     are being redeemed;

                    (7) the aggregate principal amount of Convertible
     Subordinated Notes (if less than all) that are being redeemed;

                    (8) the CUSIP number of the Convertible Subordinated Notes
     (provided that the disclaimer permitted by Section 2.13 may be made);

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

                    (10) that Convertible Subordinated Notes called for
     redemption may be converted at any time prior to the close of business on
     the last trading day immediately preceding the Redemption Date and if not
     converted prior to the close of business on such Redemption Date, the right
     of conversion with respect to the Convertible Subordinated Notes called for
     redemption will be lost; and

                                                                              23

                    (11) that in the case of Convertible Subordinated Notes or
     portions thereof called for redemption on a date that is also an Interest
     Payment Date, the interest payment and Liquidated Damages, if any, due on
     such date shall be paid to the Person in whose name the Convertible
     Subordinated Note is registered at the close of business on the relevant
     Regular Record Date.

          The notice if mailed in the manner herein provided shall be
conclusively presumed to have been given, whether or not the holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the holder of any Convertible Subordinated Note designated for
redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any Convertible Subordinated Note.

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

     SECTION 3.05. Effect of Notice of Redemption. Once notice of redemption is
mailed, Convertible Subordinated Notes called for redemption become due and
payable on the Redemption Date at the Redemption Price set forth in the
Convertible Subordinated Note.

     SECTION 3.06. Deposit of Redemption Price. On or before 10:00 a.m., New
York City time, the Redemption Date, the Company shall deposit with the Trustee
or with the Paying Agent money in immediately available funds sufficient to pay
the Redemption Price of and accrued interest (including Liquidated Damages) on
all Convertible Subordinated Notes to be redeemed on that date. The Trustee or
the Paying Agent shall return to the Company any money not required for that
purpose.

          On and after the Redemption Date, unless the Company shall default in
the payment of the Redemption Price, interest and Liquidated Damages, if
applicable, will cease to accrue on the principal amount of the Convertible
Subordinated Notes or portions thereof called for redemption and for which funds
have been set apart for payment and such Convertible Subordinated Notes, or
portions thereof, shall cease after the close of business on the Business Day
immediately preceding the Redemption Date to be convertible into Common Stock
and, except as provided in this Section 3.06 and 8.04, to be entitled to any
benefit or security under this Indenture, and the holders thereof shall have no
right in respect of such Convertible Subordinated Notes, or portions thereof,
except the right to receive the Redemption Price thereof and unpaid interest and
Liquidated Damages, if any, to (but excluding) the Redemption Date. In the case
of Convertible Subordinated Notes or portions thereof redeemed on a Redemption
Date which is also an Interest Payment Date, the interest payment and Liquidated
Damages, if any, due on such Interest Payment Date shall be paid to the Person
in whose name the Convertible Subordinated Note is registered at the close of
business on the relevant Regular Record Date.

                                                                              24

<PAGE>

     SECTION 3.07. Convertible Subordinated Notes Redeemed in Part. Upon
surrender of a Convertible Subordinated Note that is redeemed in part only, the
Company shall issue and the Trustee shall authenticate and deliver to the holder
of a Convertible Subordinated Note a new Convertible Subordinated Note equal in
principal amount to the unredeemed portion of the Convertible Subordinated Note
surrendered, at the expense of the Company, except as specified in Section 2.06.

     SECTION 3.08. Conversion Arrangement on Call for Redemption. In connection
with any redemption of Convertible Subordinated Notes, the Company may arrange
for the purchase and conversion of any Convertible Subordinated Notes by an
arrangement with one or more investment bankers or other purchasers to purchase
such Convertible Subordinated Notes by paying to the Trustee in trust for the
holders, on or before 10:00 a.m., New York City time, on the Redemption Date, an
amount not less than the applicable Redemption Price, together with interest and
Liquidated Damages, if any, accrued to the Redemption Date, of such Convertible
Subordinated Notes. Notwithstanding anything to the contrary contained in this
Article III, the obligation of the Company to pay the Redemption Price of such
Convertible Subordinated Notes, together with interest and Liquidated Damages,
if any, accrued to the Redemption Date, shall be deemed to be satisfied and
discharged to the extent such amount is so paid by the purchasers. If such an
agreement is entered into, a copy of which will be filed with the Trustee prior
to the Redemption Date, any Convertible Subordinated Notes not duly surrendered
for conversion by the holders thereof may, at the option of the Company, be
deemed, to the fullest extent permitted by law, acquired by such purchasers from
such holders and (notwithstanding anything to the contrary contained in Article
XII) surrendered by such purchasers for conversion, all as of immediately prior
to the close of business on the Redemption Date (and the right to convert any
such Convertible Subordinated Notes shall be deemed to have been extended
through such time), subject to payment of the above amount as aforesaid. At the
direction of the Company, the Trustee shall hold and dispose of any such amount
paid to it in the same manner as it would monies deposited with it by the
Company for the redemption of Convertible Subordinated Notes. Without the
Trustee's prior written consent, no arrangement between the Company and such
purchasers for the purchase and conversion of any Convertible Subordinated Notes
shall increase or otherwise affect any of the powers, duties, responsibilities
or obligations of the Trustee as set forth in this Indenture, and the Company
agrees to indemnify the Trustee from, and hold it harmless against, any loss,
liability or expense arising out of or in connection with any such arrangement
for the purchase and conversion of any Convertible Subordinated Notes between
the Company and such purchasers to which the Trustee has not consented in
writing, including the costs and expenses incurred by the Trustee in the defense
of any claim or liability arising out of or in connection with the exercise or
performance of any of its powers, duties, responsibilities or obligations under
this Indenture.

                                                                              25

                                    COVENANTS

     SECTION 4.01. Payment of Convertible Subordinated Notes. The Company shall
pay the principal of and interest (including Liquidated Damages) on the
Convertible Subordinated Notes on the dates and in the manner provided in the
Convertible Subordinated Notes. Principal, interest, the Redemption Price or the
Designated Event Payment shall be considered paid on the date due if the Trustee

of 10:00 a.m. New York City time on that date immediately available funds
designated for and sufficient to pay all principal, interest (including
Liquidated Damages), the Redemption Price and the Designated Event Payment then
due; provided, however, that money held by the Agent for the benefit of holders
of Senior Debt pursuant to the provisions of Article XI hereof or the payment of
which to the holders of the Convertible Subordinated Notes is prohibited by
Article XI shall not be considered to be designated for the payment of any
principal of or interest on the Convertible Subordinated Notes within the
meaning of this Section 4.01.

          To the extent lawful, the Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on (i)
overdue principal, at the rate borne by Convertible Subordinated Notes,
compounded semiannually; and (ii) overdue installments of interest (without
regard to any applicable grace period) at the same rate, compounded
semiannually.

     SECTION 4.02. Commission Reports. Whether or not required by the rules and
regulations of the Commission, so long as any Convertible Subordinated Notes are
outstanding, the Company will file with the Commission and furnish to the
Trustee and the holders of Convertible Subordinated Notes all quarterly and
annual financial information (without exhibits) required to be contained in a
filing with the Commission 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 the annual consolidated financial statements only, a report
thereon by the Company's independent auditors. The Company shall not be required
to file any report or other information with the Commission if the Commission
does not permit such filing, although such reports or other information will be
required to be furnished to the Trustee.

     SECTION 4.03. 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 fully performed its obligations under this Indenture and further
stating, as to each such Officer signing such certificate, that to the best of
his or her knowledge, the Company is not in default in the performance or
observance of any of the terms and conditions hereof (or, if any Default or
Event of Default shall have occurred, describing all such Defaults or Events of
Default

                                                                              26

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 of or interest (including Liquidated
Damages) on the Convertible Subordinated Notes are prohibited.

          The Company shall, so long as any of the Convertible Subordinated
Notes are outstanding, deliver to the Trustee, forthwith upon becoming aware of
any Default or Event of Default, an Officers' Certificate specifying such
Default or Event of Default.

     SECTION 4.04. Maintenance of Office or Agency. The Company shall maintain
or cause to be maintained the office or agency required under Section 2.03. The
Company shall give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency not maintained by the Trustee.
If at any time the Company shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof,
presentations, surrenders, notices and demands with respect to the Convertible
Subordinated Notes may be made or served at the Corporate Trust Office of the
Trustee.

          The Company may also from time to time designate one or more other
offices or agencies where the Convertible Subordinated Notes may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designation.

     SECTION 4.05. Continued Existence. Subject to Article V, the Company shall
do or cause to be done all things necessary to preserve and keep in full force
and effect its corporate existence.

     SECTION 4.06. Repurchase Upon Designated Event. Following a Designated
Event (the date of each such occurrence being the "Designated Event Date"), the
Company shall notify the holders of Convertible Subordinated Notes and the
Trustee in writing of such occurrence and shall make an offer (the "Designated
Event Offer") to repurchase all Convertible Subordinated Notes then outstanding
at a repurchase price in cash (the "Designated Event Payment") equal to 100% of
the principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages, if any, to, but excluding, the Designated Event Payment Date (as
defined below). Unless and until the Trustee shall receive a notice of the
occurrence of a Designated Event, the Trustee may assume without inquiry that
none has occurred.

          Notice of a Designated Event shall be mailed by or at the direction of
the Company to the holders of Convertible Subordinated Notes as shown on the
Register of such holders maintained by the Registrar not more than 20 days after
the applicable Designated Event Date at the addresses as shown on the Register
of holders maintained by the Registrar, with a copy to the Trustee and the
Paying Agent. The Designated Event Offer shall remain open until a specified
date (the "Designated Event Offer Termination Date") which is at least 20
Business Days from the date such notice is mailed. During the period specified
in such notice, holders of Convertible Subordinated Notes may elect

                                                                              27

to tender their Convertible Subordinated Notes in whole or in part in integral
multiples of $1,000 in exchange for cash. Payment shall be made by the Company

Payment, any Convertible Subordinated Note accepted for payment pursuant to the
Designated Event Offer shall cease to accrue interest and Liquidated Damages, if
applicable, on the Designated Event Payment Date and no further interest or
Liquidated Damages shall accrue on or after such date;

          (f) that holders electing to have Convertible Subordinated Notes
repurchased pursuant to a Designated Event Offer will be required to surrender

transmittal proposed by the Company and acceptable to the Trustee and the Paying

transmission or letter setting forth the name of the holder, the principal
amount of Convertible Subordinated Notes the holder delivered for purchase, the

such holder is withdrawing his election to have such Convertible Subordinated
Notes purchased;

                                                                              28

only in part will be issued Convertible Subordinated Notes equal in principal
amount to the unpurchased portion of the Convertible Subordinated Notes
surrendered;

          (i) the instructions that holders must follow in order to tender their
Convertible Subordinated Notes; and

          (j) that in the case of a Designated Event Offer Termination Date that

          In the case of any reclassification, change, consolidation, merger,
combination or sale or conveyance to which Section 12.06 applies, in which the
Common Stock of the Company is changed or exchanged as a result into the right
to receive stock, securities or other property or assets (including cash) which
includes shares of common stock of the Company or another Person that are, or
upon issuance will be, traded on a United States national securities exchange or
approved for trading on an established automated over-the-counter trading market
in the United States and such shares constitute at the time such change or
exchange becomes effective in excess of 50% of the aggregate fair market value
of such stock, securities other property and assets (including cash) (as
determined by the Company, which determination shall be conclusive and binding),
then the Person formed by such consolidation or resulting from such merger or
which acquires such assets, as the case may be, shall execute and deliver to the
Trustee a supplemental indenture (which shall comply with the TIA as in force at
the date of execution of such supplemental indenture) modifying the provisions
of this Indenture relating to the right of holders of Convertible Subordinated
Notes to cause the Company to repurchase

                                                                              29

Convertible Subordinated Notes following a Designated Event, including the
applicable provisions of this Section 4.06 and the definitions of Designated
Event, Change of Control and Termination of Trading, as appropriate, as
determined in good faith by the Company (which determination shall be conclusive
and binding), to make such provision apply to such common stock and the issuer
thereof if different from the Company and Common Stock of the Company (in lieu
of the Company and the Common Stock of the Company).

          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, to the extent such laws and regulations are
then applicable and shall include all instructions and materials that the
Company shall reasonably deem necessary to enable such holders of Convertible
Subordinated Notes to tender their Convertible Subordinated Notes.

     SECTION 4.07. Appointments to Fill Vacancies in Trustee's Office. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 7.08, a Trustee, so that there
shall at all times be a Trustee hereunder.

     SECTION 4.08. Stay, Extension and Usury Laws. The Company covenants (to the
extent that it may lawfully do so) that it shall not at any time insist upon,
plead or in any manner whatsoever claim or take the benefit or advantage of, any
stay, extension or usury law wherever enacted, now or at any time hereafter
enforced, that may affect the Company's obligation to pay the Convertible
Subordinated Notes; and the Company (to the extent that it may lawfully do so)
hereby expressly waives all benefit or advantage of any such law insofar as such
law applies to the Convertible Subordinated Notes, and covenants that it shall
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 4.09. Taxes. The Company shall, and shall cause each of its
subsidiaries to, pay prior to delinquency all taxes, assessments and government
levies; provided, however, that the Company shall not be required to pay or
cause to be paid any such tax, assessment or levy (A) if the failure to do so
will not, in the aggregate, have a material adverse impact on the Company and
its subsidiaries taken as a whole, or (B) if the amount, applicability or
validity is being contested in good faith by appropriate proceedings.

     SECTION 4.10. Liquidated Damages. If Liquidated Damages are payable by the
Company pursuant to Section 5 of the Investors Rights Agreement, the Company
shall deliver to the Trustee a certificate to the effect stating (i) the amount
of such Liquidated Damages that are payable and (ii) the date on which such
damages are payable. Unless and until a Trust Officer of the Trustee receives
such a certificate, the Trustee may assume without inquiry that no Liquidated
Damages are payable. If the Company has

                                                                              30

shall deliver to the Trustee a certificate setting forth the particulars of such
payment.

consolidation or into which the Company is merged or to which such sale,

Indenture and the Convertible Subordinated Notes.

     such acceleration having been cured, waived, rescinded or annulled for 30
     days after notice thereof from the Trustee or the holders of at least 25%
     in aggregate principal amount of the then outstanding Convertible
     Subordinated Notes; or

          (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,

               (iii) consents to the appointment of a Custodian of it or for all

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

          In the case of any Event of Default, pursuant to the provisions of
this Section 6.01, occurring by reason of any willful action (or inaction) taken
(or not taken) by or on behalf of the Company with the intention of avoiding
payment of the premium which the Company would have had to pay if the Company
then had elected to redeem the Convertible Subordinated Notes pursuant to
Paragraph 5 of the Convertible Subordinated Notes, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law,
upon the acceleration of the Convertible Subordinated Notes notwithstanding
anything contained in this Indenture or in the Convertible Subordinated Notes to
the contrary.

          If an Event of Default occurs prior to any date on which the Company
is prohibited from redeeming the Convertible Subordinated Notes, pursuant to
Paragraph 5 of the Convertible Subordinated Notes, by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding the prohibition on redemption of the Convertible
Subordinated Notes prior to such date, then the premium specified in this
Indenture shall also become immediately due and payable to the extent permitted
by law upon the acceleration of the Convertible Subordinated Notes.

     SECTION 6.02. Acceleration. If an Event of Default (other than an Event of
Default with respect to the Company specified in clauses (h) and (i) of Section
6.01) occurs and is continuing, then and in every such case the Trustee, by
written notice to the Company, or the holders of at least 25% in aggregate
principal amount of the then

                                                                              34

<PAGE>

outstanding Convertible Subordinated Notes, by written notice to the Company and
the Trustee, may declare the unpaid principal of, premium, if any, and accrued
and unpaid interest and Liquidated Damages, if any, on all the Convertible
Subordinated Notes to be due and payable. Upon such declaration such principal
amount, premium, if any, and accrued and unpaid interest and Liquidated Damages,
if any, shall become immediately due and payable, notwithstanding anything
contained in this Indenture or the Convertible Subordinated Notes to the
contrary, but subject to the provisions of Article XI hereof. If any Event of
Default with respect to the Company specified in clauses (h) or (i) of Section
6.01 occurs, all unpaid principal of and premium, if any, and accrued and unpaid
interest and Liquidated Damages, if any, on the Convertible Subordinated Notes
then outstanding shall become automatically due and payable subject to the
provisions of Article XI hereof, without any declaration or other act on the
part of the Trustee or any holder of Convertible Subordinated Notes.

          The holders of a majority in aggregate principal amount of the then
outstanding Convertible Subordinated Notes by notice to the Trustee may rescind
an acceleration of the Convertible Subordinated Notes and its consequences if
all existing Events of Default (other than nonpayment of principal of or
premium, if any, and interest and Liquidated Damages, if any, on the Convertible
Subordinated Notes which has become due solely by virtue of such acceleration)
have been cured or waived and if the rescission would not conflict with any
judgment or decree of any court of competent jurisdiction. No such rescission
shall affect any subsequent Default or Event of Default or impair any right
consequent thereto.

     SECTION 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy by proceeding at law or
in equity to collect the payment of principal of or interest or Liquidated
Damages, if applicable, on the Convertible Subordinated Notes or to enforce the
performance of any provision of the Convertible Subordinated Notes or this
Indenture. The Trustee may maintain a proceeding even if it does not possess any
of the Convertible Subordinated Notes or does not produce any of them in the
proceeding. A delay or omission by the Trustee or any holder of a Convertible
Subordinated Note in exercising any right or remedy occurring 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 6.04. Waiver of Past Defaults. The holders of a majority in
aggregate principal amount of the Convertible Subordinated Notes then
outstanding may, on behalf of the holders of all the Convertible Subordinated
Notes, waive an existing Default or Event of Default and its consequences,
except a Default or Event of Default in the payment of the principal of,
premium, if any, or interest or Liquidated Damages, if applicable, on the
Convertible Subordinated Notes (other than the non-payment of principal of and
premium, if any, and interest or Liquidated Damages, if any, on the Convertible
Subordinated Notes which has become due solely by virtue of an acceleration
which has been duly rescinded as provided above), or in respect of a covenant or
provision of this Indenture which cannot be modified or amended without the

                                                                              35

<PAGE>

consent of all holders of Convertible Subordinated Notes. When a Default or
Event of Default is waived, it is cured and stops continuing. No waiver shall
extend to any subsequent or other Default or Event of Default or impair any
right consequent thereon.

     SECTION 6.05. Control by Majority. The holders of a majority in aggregate
principal amount of the then outstanding Convertible Subordinated Notes 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 that the Trustee determines may be unduly prejudicial to the
rights of other holders of Convertible Subordinated Notes or that may involve
the Trustee in personal liability; provided that the Trustee shall have no duty
or obligation (subject to Section 7.01) to ascertain whether or not such actions
of forbearances are unduly prejudicial to such holders; provided, further, that
the Trustee may take any other action the Trustee deems proper that is not
inconsistent with such directions.

     SECTION 6.06. Limitation on Suits. A holder of a Convertible Subordinated
Note may not pursue any remedy with respect to this Indenture or the Convertible
Subordinated Notes unless:

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

                    (2) the holders of at least 25% in principal amount of the
     then outstanding Convertible Subordinated Notes make a request to the
     Trustee to pursue the remedy;

                    (3) such holder or holders offer and, if requested, provide
     to the Trustee indemnity satisfactory to the Trustee against any loss,
     liability or expense;

                    (4) the Trustee does not comply with the request within 60
     days after receipt of the request and the offer and, if requested, the
     provision of indemnity; and

                    (5) during such 60-day period the holders of a majority in
     principal amount of the then outstanding Convertible Subordinated Notes do
     not give the Trustee a direction inconsistent with the request.

          A holder of a Convertible Subordinated Note may not use this Indenture
to prejudice the rights of another holder or to obtain a preference or priority
over another holder.

     SECTION 6.07. Rights of Holders To Receive Payment. Subject to the
provisions of Article XI hereof, notwithstanding any other provision of this
Indenture, the

                                                                              36

<PAGE>

right of any holder of a Convertible Subordinated Note to receive payment of
principal, premium, if any, and interest and Liquidated Damages, if any, on the
Convertible Subordinated Note, on or after the respective due dates expressed in
the Convertible Subordinated Note, or to bring suit for the enforcement of any
such payment on or after such respective dates, or to bring suit for the
enforcement of the right to convert the Convertible Subordinated Note shall not
be impaired or affected without the consent of the holder of a Convertible
Subordinated Note.

     SECTION 6.08. Collection Suit by Trustee. If an Event of Default specified
in Section 6.01(a), (b) or (d) 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 and Liquidated Damages, if any,
remaining unpaid on the Convertible Subordinated Notes and interest and
Liquidated Damages, if any, on overdue principal and interest and Liquidated
Damages, if any, 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 6.09. 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 holders of Convertible
Subordinated Notes 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 holder of a Convertible Subordinated Note any plan of reorganization,
arrangement, adjustment or composition affecting the Convertible Subordinated
Notes or the rights of any holder thereof, or to authorize the Trustee to vote
in respect of the claim of any holder in any such proceeding.

     SECTION 6.10. Priorities. If the Trustee collects any money pursuant to
this Article VI, it shall pay out the money in the following order:

               First: to the Trustee for amounts due under Section 7.07,
          including payment of all compensation, expenses and liabilities
          incurred, and all advances made, by the Trustee, and the costs and
          expenses of collection;

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

               Third: to holders of Convertible Subordinated Notes for amounts
          due and unpaid on the Convertible Subordinated Notes for principal,
          premium, if any, and interest and Liquidated Damages, if any, ratably,
          without preference or priority of any kind, according to the amounts
          due and payable on the Convertible Subordinated Notes for principal,
          premium, if any, and interest and Liquidated Damages, if any,
          respectively; and

                                                                              37

<PAGE>

               Fourth: to the Company.

          The Trustee may fix a special record date and payment date for any
payment to holders of Convertible Subordinated Notes made pursuant to this
section. At least 15 days before any such special record date, the Trustee shall
mail to holders of the Convertible Subordinated Notes a notice that states the
special record date, payment date and amount of such interest to be paid.

     SECTION 6.11. 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, other than the Trustee, 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 6.07 or a suit by
holders of more than 10% in principal amount of the then outstanding Convertible
Subordinated Notes.

                                   ARTICLE VII

                                   THE TRUSTEE

          The Trustee hereby accepts the trust imposed upon it by this Indenture
and covenants and agrees to perform the same, as herein expressed. Whether or
not herein expressly so provided, every provision of this Indenture relating to
the conduct or affecting the liability of or affording protection to the Trustee
shall be subject to the provisions of this Article VII.

     SECTION 7.01. Duties of the Trustee.

          (a) If an Event of Default known to the Trustee 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 his or her own affairs.

          (b) Except during the continuance of an Event of Default known to the
Trustee:

                    (1) The duties of the Trustee shall be determined solely by
     the express provisions of this Indenture and the Trustee need perform only
     those duties that are specifically set forth in this Indenture and no
     others and no implied covenants or obligations shall be read into this
     Indenture against the Trustee; and

                                                                              38

<PAGE>

                    (2) In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon any statements, certificates or
     opinions 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 form required by
     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:

                    (1) This paragraph does not limit the effect of paragraph
     (b) of this Section;

                    (2) The Trustee shall not be liable for any error of
     judgment made in good faith by a Trust Officer, unless it is proved that
     the Trustee was negligent in ascertaining the pertinent facts; and

                    (3) 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 6.05.

          (d) Whether or not therein expressly so provided, every provision of
this Indenture that is in any way related to the Trustee is subject to
paragraphs (a), (b) and (c) of this Section 7.01.

          (e) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or incur any financial liability in the performance of any
of its duties or the exercise of any of its rights and powers hereunder, if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk of liability is not reasonably assured to
it.

          (f) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree with the Company. Money held in trust by
the Trustee need not be segregated from other funds except to the extent
required by law.

     SECTION 7.02. Rights of the Trustee.

          (a) The Trustee may rely on and shall be protected in acting or
refraining from acting upon any resolution, Officers' Certificate, or any other
certificate, statement, instrument, opinion, report, notice, request, consent,
order, security or other document 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 contained therein.

          (b) Any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof is herein specifically prescribed). In addition,
before the Trustee acts or

                                                                              39

<PAGE>

refrains from acting, it may require an Officers' Certificate, 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. The Trustee may consult with counsel and the written advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and
protection from liability in respect of any action taken, suffered or omitted by
it hereunder in good faith and in reliance thereon.

          (c) The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through its attorneys and
agents and other Persons not regularly in its employ and shall not be
responsible for the misconduct or negligence of any attorney or agent appointed
with due care.

          (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith without negligence or willful misconduct which it believes
to be authorized or within its discretion, rights or powers.

          (e) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by Officers of the Company.

          (f) The Trustee shall not be required to give any bond or surety in
respect of the performance of its powers and duties hereunder.

          (g) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
discretion of any of the holders of Convertible Subordinated Notes pursuant to
the provisions of this Indenture, unless such holders have offered to the
Trustee security or indemnity satisfactory to it against the costs, expenses and
liabilities which might be incurred therein or thereby.

          (h) 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, consent, order, security or other document
unless requested in writing to do so by the holders of not less than a majority
in aggregate principal amount of the Convertible Subordinated Notes then
outstanding, provided that if the Trustee determines in its discretion to make
any such investigation, then it shall be entitled, upon reasonable prior notice
and during normal business hours, to examine the books and records and the
premises of the Company, personally or by agent or attorney, and the reasonable
expenses of every such examination shall be paid by the Company or, if paid by
the Trustee or any predecessor Trustee, shall be reimbursed by the Company upon
demand.

          (i) The permissive rights of the Trustee to do things enumerated in
this Indenture shall not be construed as a duty and the Trustee shall not be
answerable for other than its negligence or willful misconduct

          (j) The Trustee shall not be responsible for the computation of any
adjustment to the Conversion Price or for any determination as to whether an
adjustment

                                                                              40

<PAGE>

is required and shall not be deemed to have knowledge of any adjustment unless
and until it shall have received the notice from the Company contemplated by
Section 12.05(j).

     SECTION 7.03. Individual Rights of the Trustee. Subject to Sections 7.10
and 7.11, the Trustee in its individual or any other capacity may become the
owner or pledgee of Convertible Subordinated Notes with the same rights it would
have if it were not the Trustee and may otherwise deal with the Company or an
Affiliate of the Company and receive, collect, hold and retain collections from
the Company with the same rights it would have if it were not Trustee. Any Agent
may do the same with like rights.

     SECTION 7.04. Trustee's Disclaimer. The Trustee shall not be responsible
for and makes no representation as to the validity or adequacy of this Indenture
or the Convertible Subordinated Notes. It shall not be accountable for the
Company's use of the proceeds from the Convertible Subordinated Notes or any
money paid to the Company or upon the Company's direction under any provision of
this Indenture. It shall not be responsible for the use or application of any
money received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the
Convertible Subordinated Notes or any other document in connection with the sale
of the Convertible Subordinated Notes or pursuant to this Indenture other than
its certificate of authentication.

     SECTION 7.05. Notice of Defaults. If a Default or Event of Default occurs
and is continuing and if it is known to the Trustee, the Trustee shall mail to
each holder of a Convertible Subordinated Note a notice of the Default or Event
of Default within 60 days after it occurs. A Default or an Event of Default
shall not be considered known to the Trustee unless it is a Default or Event of
Default in the payment of principal or interest when due under Section 6.01(a),
(b) or (d) or the Trustee shall have received notice thereof, in accordance with
this Indenture, from the Company or from the holders of a majority in principal
amount of the outstanding Convertible Subordinated Notes. Except in the case of
a Default or Event of Default in payment of principal of, premium, if any, or
interest or Liquidated Damages, if any, on any Convertible Subordinated Note,
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 interest
of the holders of the Convertible Subordinated Notes.

     SECTION 7.06. Reports by the Trustee to Holders. Within 60 days after the
reporting date stated in Section 10.10, the Trustee shall mail to holders of
Convertible Subordinated Notes a brief report dated as of such reporting date
that complies with TIA Section 313(a) (but if no event described in TIA Section
313(a) has occurred within twelve months preceding the reporting date, no report
need be transmitted). 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 holders of
Convertible Subordinated Notes shall be filed, at the expense of the Company, by
the Trustee with the Commission and each stock exchange or securities market, if
any, on which the

                                                                              41

<PAGE>

Convertible Subordinated Notes are listed. The Company shall timely notify the
Trustee when the Convertible Subordinated Notes are listed or quoted on any
stock exchange or securities market.

     SECTION 7.07. Compensation and Indemnity. The Company shall pay to the
Trustee from time to time and the Trustee shall be entitled to reasonable
compensation for its acceptance of this Indenture and its services hereunder.
The Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee promptly
upon request for all reasonable disbursements, advances and expenses incurred or
made by or on behalf of it in addition to the compensation for its services.
Such expenses may include the reasonable compensation, disbursements and
expenses of the Trustee's agents, counsel and other persons not regularly in its
employ.

          The Company shall indemnify the Trustee against any loss, liability or
expense incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture and the trusts hereunder,
including the costs and expenses of defending itself against or investigating
any claim of liability in the premises, except as set forth in the next
paragraph. The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity. Failure by the Trustee to so notify the Company shall not
relieve the Company of its obligations hereunder. The Company shall defend the
claim with counsel designated by the Company, who may be outside counsel to the
Company but shall in all events be reasonably satisfactory to the Trustee, and
the Trustee shall cooperate in the defense. In addition, the Trustee may retain
one separate counsel and, if deemed advisable by such counsel, local counsel,
and the Company shall pay the reasonable fees and expenses of such separate
counsel and local counsel. The indemnification herein extends to any settlement,
provided that the Company will not be liable for any settlement made without its
consent, provided, further, that such consent will not be unreasonably withheld.

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

          The Trustee shall have a lien prior to the Convertible Subordinated
Notes on all money or property held or collected by the Trustee to secure the
Company's payment obligations in this Section 7.07, except that held in trust to
pay principal and interest and Liquidated Damages, if any, on Convertible
Subordinated Notes. Such liens and the Company's obligations under this Section
7.07 shall survive the satisfaction and discharge of this Indenture.

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(h) or (i) occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and

     SECTION 7.08. Replacement of the 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
7.08.

          The Trustee may resign at any time and be discharged from the trust
hereby created by so notifying the Company. The holders of a majority in
principal amount of the then outstanding Convertible Subordinated Notes may
remove the Trustee by so notifying the Trustee and the Company in writing and
may appoint a successor Trustee. The Company may remove the Trustee if:

                    (1) the Trustee fails to comply with Section 7.10;

                    (2) 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;

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

                    (4) the Trustee becomes incapable of acting.

          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 holders
of a majority in principal amount of the then outstanding Convertible
Subordinated Notes may appoint a successor Trustee to replace the successor
Trustee appointed by the Company.

          If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
holders of at least 10% in principal amount of the then outstanding Convertible
Subordinated Notes may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

          If the Trustee after written request by any holder of a Convertible
Subordinated Note who has been a holder for at least six months fails to comply
with Section 7.10, such holder 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, 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 holders of Convertible Subordinated Notes. The retiring Trustee
shall promptly transfer all property held by it as Trustee to the successor
Trustee, provided that all sums owing to the retiring Trustee hereunder have
been paid and subject to the lien provided for in Section 7.07. Notwithstanding
the replacement of the Trustee pursuant to this Section 7.08, the Company's
obligations under Section 7.07 shall

                                                                              43

<PAGE>

continue for the benefit of the retiring Trustee with respect to expenses and
liabilities incurred by it prior to such replacement.

          Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in the
preceding paragraph.

     SECTION 7.09. Successor Trustee by Merger, etc. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all of its
corporate trust business (including the trust created by this Indenture) to,
another corporation or national banking association, the resulting, surviving or
transferee corporation or national banking association without any further act
shall be the successor Trustee with the same effect as if the successor Trustee
had been named as the Trustee herein.

     SECTION 7.10. Eligibility, Disqualification. This Indenture shall always
have a Trustee who satisfies the requirements of TIA Section 310(a)(1). The
Trustee shall always have a combined capital and surplus as stated in Section
10.10. The Trustee is subject to TIA Section 310(b) regarding the
disqualification of a trustee upon acquiring a conflicting interest.

     SECTION 7.11. Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship set forth 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.

lost or stolen and in lieu of or in substitution for which other Convertible
Subordinated Notes have been authenticated and delivered) not theretofore
canceled or delivered to the Trustee for cancellation, including principal and
premium, if any, and interest and Liquidated Damages, if any, due or to become

<PAGE>

the case may be, and if in either case the Company also pays, or causes to be
paid, all other sums payable hereunder by the Company, then this Indenture shall
cease to be of further effect (except as to (i) rights of registration of
transfer, substitution, replacement and exchange and conversion of Convertible
Subordinated Notes, (ii) rights hereunder of holders of Convertible Subordinated
Notes to receive payments of principal of and premium, if any, and interest and
Liquidated Damages, if any, on, the Convertible Subordinated Notes, (iii) the
obligations under Sections 2.03 and 8.05 hereof and (iv) the rights, obligations
and immunities of the Trustee hereunder), and the Trustee, on demand of the
Company accompanied by an Officers' Certificate and an Opinion of Counsel as
required by Section 10.04 and at the Company's cost and expense, shall execute
proper instruments acknowledging satisfaction of and discharging this Indenture;
the Company, however, hereby agrees to reimburse the Trustee for any costs or
expenses thereafter reasonably and properly incurred by the Trustee and to
compensate the Trustee for any services thereafter reasonably and properly
rendered by the Trustee in connection with this Indenture or the Convertible
Subordinated Notes.

     SECTION 8.02. Deposited Monies to be Held in Trust by Trustee. Subject to
Section 8.04, all monies deposited with the Trustee pursuant to Section 8.01
shall be held in trust and applied by it to the payment, notwithstanding the
provisions of Article XI, either directly or through the Paying Agent, to the
holders of the particular Convertible Subordinated Notes for the payment or
redemption of which such monies have been deposited with the Trustee, of all
sums due and to become due thereon for principal and interest, and Liquidated
Damages, if any, and premium, if any.

     SECTION 8.03. Paying Agent to Repay Monies Held. Upon the satisfaction and
discharge of this Indenture, all monies then held by any Paying Agent (other
than the Trustee) shall, upon the Company's demand, be repaid to it or paid to
the Trustee, and thereupon such Paying Agent shall be released from all further
liability with respect to such monies.

     SECTION 8.04. Return of Unclaimed Monies. Subject to the requirements of
applicable law, any monies deposited with or paid to the Trustee for payment of
the principal of, premium, if any, or interest (including Liquidated Damages) if
any on Convertible Subordinated Notes and not applied but remaining unclaimed by
the holders thereof for two years after the date upon which the principal of,
premium, if any, or interest (including Liquidated Damages) on such Convertible
Subordinated Notes, as the case may be, have become due and payable, shall be
repaid to the Company by the Trustee on demand; 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 holder of a
Convertible Subordinated Note entitled thereto no less than 30 days prior to
such payment and all liability of the Trustee shall thereupon cease with respect
to such monies; and the holder of any of the Convertible Subordinated Notes
shall thereafter look only to the Company for any payment which such holder may
be entitled to collect unless an applicable abandoned property law designates
another Person.

                                                                              45

<PAGE>

     SECTION 8.05. Reinstatement. If the Trustee or the Paying Agent is unable
to apply any money in accordance with Section 8.02 by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Convertible Subordinated Notes shall be revived and reinstated
as though no deposit had occurred pursuant to Section 8.01 until such time as
the Trustee or the Paying Agent is permitted to apply all such money in
accordance with Section 8.02; provided, however, that if the Company makes any
payment of interest (including Liquidated Damages) on or principal of any
Convertible Subordinated Note following the reinstatement of its obligations,
the Company shall be subrogated to the rights of the holders thereof to receive
such payment from the money held by the Trustee or Paying Agent.

     SECTION 9.01. Without the Consent of Holders. The Company and the Trustee
may amend this Indenture or the Convertible Subordinated Notes without notice to
or the consent of any holder of a Convertible Subordinated Note for the purposes
of:

          (a) curing any ambiguity or correcting or supplementing any defective
or inconsistent provision contained in this Indenture or making any other
changes in the provisions of this Indenture which the Company and the Trustee
may deem necessary or desirable provided such amendment does not materially and
adversely affect the legal rights under the Indenture of the holders of
Convertible Subordinated Notes.

          (b) providing for uncertificated Convertible Subordinated Notes in
addition to or in place of certificated Convertible Subordinated Notes;

<PAGE>

          (g) complying with the requirements of the Commission in order to
effect or maintain the qualification of the Indenture under the TIA.

     SECTION 9.02. With the Consent of Holders. Subject to Section 6.07, the
Company and the Trustee may amend this Indenture or the Convertible Subordinated
Notes with the written consent of the holders of at least a majority in
principal amount of the then outstanding Convertible Subordinated Notes
(including consents obtained in connection with a tender offer or exchange offer
for Convertible Subordinated Notes).

          Subject to Sections 6.04 and 6.07, the holders of a majority in
principal amount of the Convertible Subordinated Notes then outstanding may also
waive compliance in a particular instance by the Company with any provision of
this Indenture or the Convertible Subordinated Notes.

          However, without the consent of each holder of a Convertible
Subordinated Note affected, an amendment or waiver under this Section may not
(with respect to any Convertible Subordinated Notes held by a non-consenting
holder):

          (a) reduce the principal amount of Convertible Subordinated Notes
     whose holders must consent to an amendment, supplement or waiver;

          (b) reduce the principal of, Redemption Price, Designated Event
     Payment (including any Make Whole Premium payable) (as applicable), or
     premium on or change the fixed maturity of any Convertible Subordinated

     including defaulted interest or Liquidated Damages on any Convertible
     Subordinated Note;

          (d) waive a Default or Event of Default in the payment of principal of
     or premium, if any, or interest or Liquidated Damages on the Convertible
     Subordinated Notes (except a rescission of acceleration of the Convertible
     Subordinated Notes by the holders of at least a majority in aggregate
     principal amount of the Convertible Subordinated Notes then outstanding and
     a waiver of the payment default that resulted from such acceleration);

          (e) make the principal of, or premium, if any, or interest or
     Liquidated Damages on any Convertible Subordinated Note payable in money
     other than as provided for herein and in the Convertible Subordinated
     Notes;

          (f) make any change in the provisions of this Indenture relating to
     waivers of past Defaults or Events of Default or the rights of holders of
     Convertible Subordinated Notes to receive payments of principal of,
     premium, if any, or interest or Liquidated Damages on the Convertible
     Subordinated Notes;

                                                                              47

<PAGE>

          (g) waive a redemption payment with respect to any Convertible
     Subordinated Notes;

          (h) except as permitted herein (including Section 9.01(a)), increase
     the Conversion Price or modify the provisions contained herein relating to
     conversion of the Convertible Subordinated Notes in a manner adverse to the
     holders thereof; or

          (i) make any change to the abilities of holders of Convertible
     Subordinated Notes to enforce their rights hereunder or the provisions of
     clauses (a) through (i) of this Section 9.02.

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

          After an amendment or waiver under this Article IX becomes effective,
the Company shall mail to holders of Convertible Subordinated Notes a notice
briefly describing the amendment or waiver.

          In order to amend any provisions of Article XI, holders of at least
75% in aggregate principal amount of Convertible Subordinated Notes then
outstanding must consent to such amendment if such amendment would adversely
affect the rights of holders of Convertible Subordinated Notes.

     SECTION 9.03. Compliance with the Trust Indenture Act. Every amendment to
this Indenture or the Convertible Subordinated Notes shall be set forth in a
supplemental indenture that complies with the TIA as then in effect.

     SECTION 9.04. Revocation and Effect of Consents. Until an amendment or
waiver becomes effective, a consent to it by a holder of a Convertible
Subordinated Note is a continuing consent by the holder and every subsequent
holder of a Convertible Subordinated Note or portion of a Convertible
Subordinated Note that evidences the same debt as the consenting holder's
Convertible Subordinated Note, even if notation of the consent is not made on
any Convertible Subordinated Note. However, any such holder or subsequent holder
may revoke the consent as to his or her Convertible Subordinated Note or portion
of a Convertible Subordinated Note if the Trustee receives the notice of
revocation before the date on which the Trustee receives an Officers'
Certificate certifying that the holders of the requisite principal amount of
Convertible Subordinated Notes have consented to the amendment or waiver.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the holders of Convertible Subordinated Notes
entitled to consent to any amendment or waiver. If a record date is fixed, then
notwithstanding the provisions of the immediately preceding paragraph, those
Persons who were holders of

                                                                              48

<PAGE>

Convertible Subordinated Notes at such record date (or their duly designated
proxies), and only those Persons, shall be entitled to consent to such amendment
or waiver or to revoke any consent previously given, whether or not such Persons
continue to be holders after such record date. No consent shall be valid or
effective for more than 90 days after such record date unless consents from
holders of the principal amount of Convertible Subordinated Notes required
hereunder for such amendment or waiver to be effective shall have also been
given and not revoked within such 90-day period.

          After an amendment or waiver becomes effective it shall bind every
holder of a Convertible Subordinated Note, unless it is of the type described in
clauses (a) through (i) of Section 9.02. In such cases, the amendment or waiver
shall bind each holder of a Convertible Subordinated Note who has consented to
it and every subsequent holder of a Convertible Subordinated Note or portion of
a Convertible Subordinated Note that evidences the same debt as the consenting
holder's Convertible Subordinated Note.

     SECTION 9.05. Notation on or Exchange of Convertible Subordinated Notes.
Convertible Subordinated Notes authenticated and delivered after the execution
of any supplemental indenture pursuant to this Article IX may, and shall if
required by the Trustee, bear a notation in the form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Convertible Subordinated Notes so modified as to conform, in
the opinion of the Company and the Trustee, to any such supplemental indenture
may be prepared and executed by the Company and authenticated and delivered by
the Trustee in exchange for outstanding Convertible Subordinated Notes without
charge to the holders of the Convertible Subordinated Notes, except as specified
in Section 2.06.

     SECTION 9.06. Trustee Protected. The Trustee shall sign any amendment or
supplemental indenture authorized pursuant to this Article IX if such amendment
or supplemental indenture does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may, but need
not, sign it. In signing such amendment or supplemental indenture, the Trustee
shall be entitled to receive, and shall be fully protected in relying upon, an
Officers' Certificate and an Opinion of Counsel as conclusive evidence that such
amendment or supplemental indenture is authorized or permitted by this
Indenture, that it is not inconsistent herewith, and that it will be valid and
binding upon the Company in accordance with its terms.

                               GENERAL PROVISIONS

     SECTION 10.01. Trust Indenture Act Controls. If any provision of this
Indenture limits, qualifies or conflicts with the duties imposed by TIA Section
318(c), such duties imposed by such section of the TIA shall control. If any
provision of this Indenture expressly modifies or excludes any provision of the
TIA that may be so modified or excluded, the Indenture provision so modifying or
excluding such provision of the TIA shall be deemed to apply.

                                                                              49

Note shall be mailed by first-class mail, with postage prepaid, to his or her

with respect to other holders.

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

          If the Company sends a notice or communication to holders of
Convertible Subordinated Notes, it shall send a copy to the Trustee and each
Agent at the same time.

          All notices or communications shall be in writing.

     reasonably satisfactory to the Trustee (which shall include the statements
     set forth in Section 10.05) stating that, in the opinion of such person,
     all conditions precedent and covenants, if any, provided for in this
     Indenture relating to the proposed action have been complied with; and

     conditions precedent and covenants have been complied with.

     SECTION 10.05. Statements Required in Certificate or Opinion. Each

                    (4) a statement as to whether or not, in the opinion of such
     person, such condition or covenant has been complied with.

          Any Officers' Certificate may be based, insofar as it relates to legal
matters, upon an Opinion of Counsel, unless such Officer knows that the opinion
with respect to the matters upon which his or her certificate may be based as
aforesaid is erroneous. Any Opinion of Counsel may be based, insofar as it
relates to factual matters, upon certificates, statements or opinions of, or
representations by, an officer or officers of the Company, or other Persons or
firms deemed appropriate by such counsel, unless such counsel knows that the
certificates, statements or opinions or representations with respect to the
matters upon which his or her opinion may be based as aforesaid are erroneous.

          Any Officers' Certificate, statement or Opinion of Counsel may be

Corporate Trust Office of the Trustee is located or the City of New York, New
York are not required to be open, and a "Business Day" is any day that is not a

specified in this Indenture, including, without limitation, a Redemption Date
under Paragraph 5 of Convertible Subordinated Notes, is a Legal Holiday, then

or stockholder, as such, of the Company from time to time shall have any
liability for any obligations of the Company under the Convertible Subordinated
Notes or this Indenture or for any claim based on, in respect of, or by reason

Subordinated Note waives and releases all such liability. This waiver and
release are part of the consideration for the Convertible Subordinated Notes.
Each of such directors, officers, employees and stockholders is a third party
beneficiary of this Section 10.08.

                                   ARTICLE XI

                                  SUBORDINATION

     SECTION 11.01. Agreement to Subordinate. The Company agrees, and each
holder of Convertible Subordinated Notes by accepting a Convertible Subordinated
Note agrees, that the indebtedness evidenced by the Convertible Subordinated
Note is subordinated in right of payment, to the extent and in the manner
provided in this Article XI, to the prior payment in full in cash or payment
satisfactory to holders of Senior Debt of all Senior Debt (whether outstanding
on the Issue Date or thereafter created, incurred, assumed or guaranteed), and
that the subordination is for the benefit of the holders of Senior Debt. The
Company agrees, and each holder of Convertible Subordinated Notes by accepting a
Convertible Subordinated Note agrees, that the indebtedness evidenced by the
Convertible Subordinated Note is pari passu in right of payment to the Existing
Convertible Subordinated Notes.

                                                                              53

     SECTION 11.02. Liquidation; Dissolution; Bankruptcy. Upon any distribution
to creditors of the Company in a liquidation or dissolution of the Company or in
a bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company or its property, in an assignment for the benefit of
creditors or any marshaling of the Company's assets and liabilities:

                    (1) holders of Senior Debt shall be entitled to receive
     payment in full of all Obligations due in respect of such Senior Debt
     (including interest and Liquidated Damages, if any, after the commencement
     of any such proceeding at the rate specified in the applicable Senior Debt)
     in cash or other payment satisfactory to the holders of the Senior Debt
     before holders of Convertible Subordinated Notes shall be entitled to
     receive any payment with respect to the Convertible Subordinated Notes; and

                    (2) until all Senior Debt is paid in full in cash or other
     payment satisfactory to the holders of the Senior Debt, any distribution to
     which holders of Convertible Subordinated Notes would be entitled but for
     this Article XI shall be made to holders of Senior Debt, as their interests
     may appear.

     SECTION 11.03. Default on Senior Debt and/or Designated Senior Debt. The
Company may not make any payment or distribution to the Trustee or any holder of
Convertible Subordinated Notes in respect of Obligations with respect to the
Convertible Subordinated Notes and may not acquire from the Trustee or any
holder of Convertible Subordinated Notes any Convertible Subordinated Notes
until all Senior Debt has been paid in full in cash or other payment
satisfactory to the holders of the Senior Debt if:

               (i) a default in the payment of any principal of, premium, if
     any, interest, rent or other Obligations in respect of Senior Debt occurs
     and is continuing beyond any applicable grace period in the agreement,
     indenture or other document governing such Senior Debt; or

               (ii) a default, other than a payment default, on Designated
     Senior Debt occurs and is continuing that then permits holders of such
     Designated Senior Debt to accelerate its maturity and the Trustee receives
     a notice of the default (a "Payment Blockage Notice") from a Person who may
     give it pursuant to Section 11.11 hereof.

          If the Trustee receives any Payment Blockage Notice pursuant to
Section 11.03 (ii) hereof, no subsequent Payment Blockage Notice shall be
effective for purposes of such Section unless and until at least 365 days shall
have elapsed since the effectiveness of the immediately prior Payment Blockage
Notice. No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the
basis for a subsequent Payment Blockage Notice.

                                                                              54

<PAGE>

          The Company may and shall resume payments on and distributions in
respect of the Convertible Subordinated Notes and may acquire them upon the
earlier of:

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

                    (2) in the case of a nonpayment default referred to in
     Section 11.03(ii) hereof, the earlier of the date upon which the default is
     cured or waived ceases to exist or 179 days after notice is received if the
     maturity of such Designated Senior Debt has not been accelerated,

if this Article XI otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

     SECTION 11.04. Acceleration of Convertible Subordinated Notes. In the event
of the acceleration of the Convertible Subordinated Notes because of an Event of
Default, the Company may not make any payment or distribution to the Trustee or
any holder of Convertible Subordinated Notes in respect of Obligations with
respect to Convertible Subordinated Notes and may not acquire or purchase from
the Trustee or any holder of Convertible Subordinated Notes any Convertible
Subordinated Notes until all Senior Debt has been paid in full in cash or other
payment satisfactory to the holders of Senior Debt or such acceleration is
rescinded in accordance with the terms of this Indenture.

          If payment of the Convertible Subordinated Notes is accelerated
because of an Event of Default, the Company or the Trustee shall promptly notify
holders of Senior Debt or trustee(s) of such Senior Debt of the acceleration.

     SECTION 11.05. When Distribution Must Be Paid Over. In the event that the
Trustee, any holder of Convertible Subordinated Notes or any other Person
receives any payment or distributions of assets of the Company of any kind with
respect to the Convertible Subordinated Notes in contravention of any terms
contained in this Indenture, whether in cash, property or securities, including,
without limitation by way of set-off or otherwise, then such payment shall be
held by the recipient in trust for the benefit of holders of Senior Debt, and
shall be immediately paid over and delivered to the holders of Senior Debt or
the representative(s), to the extent necessary to make payment in full of all
Senior Debt remaining unpaid, after giving effect to any concurrent payment or
distribution or provision therefore, to or for the holders of Senior Debt;
provided that the foregoing shall apply to the Trustee only if the Trustee has
actual knowledge (as determined in accordance with Section 11.11) that such
payment or distribution is prohibited by this Indenture.

          With respect to the holders of Senior Debt, the Trustee undertakes to
perform only such obligations on the part of the Trustee as are specifically set
forth in this Article XI, 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 be deemed to owe any fiduciary duty to the
holders of Senior Debt, and shall not be liable to

                                                                              55

<PAGE>

any such holders if the Trustee shall pay over or distribute to or on behalf of
holders of Convertible Subordinated Notes or the Company or any other Person
money or assets to which any holders of Senior Debt shall be entitled by virtue
of this Article XI, except if such payment is made as a result of the willful
misconduct or gross negligence of the Trustee.

     SECTION 11.06. Notice by Company. The Company shall promptly notify the
Trustee of any facts known to the Company that would cause a payment of any
Obligations with respect to the Convertible Subordinated Notes or the purchase
of any Convertible Subordinated Notes by the Company to violate this Article XI,
but failure to give such notice shall not affect the subordination of the
Convertible Subordinated Notes to the Senior Debt as provided in this Article
XI.

     SECTION 11.07. Subrogation. After all Senior Debt is paid in full and until
the Convertible Subordinated Notes are paid in full, holders of Convertible
Subordinated Notes shall be subrogated (equally and ratably with all other
indebtedness pari passu with the Convertible Subordinated Notes) to the rights
of holders of Senior Debt to receive distributions applicable to Senior Debt to
the extent that distributions otherwise payable to the holders of Convertible
Subordinated Notes have been applied to the payment of Senior Debt. A
distribution made under this Article XI to holders of Senior Debt that otherwise
would have been made to holders of Convertible Subordinated Notes is not, as
between the Company and holders of Convertible Subordinated Notes, a payment by
the Company on the Convertible Subordinated Notes.

     SECTION 11.08. Relative Rights. This Article XI defines the relative rights
of holders of Convertible Subordinated Notes and holders of Senior Debt. Nothing
in this Indenture shall:

                    (1) impair, as between the Company and holders of
     Convertible Subordinated Notes, the obligation of the Company, which is
     absolute and unconditional, to pay principal of, premium, if any, and
     interest (including Liquidated Damages) on the Convertible Subordinated
     Notes in accordance with their terms;

                    (2) affect the relative rights of holders of Convertible
     Subordinated Notes and creditors (other than with respect to Senior Debt)
     of the Company, other than their rights in relation to holders of Senior
     Debt; or

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

                                                                              56

<PAGE>

          If the Company fails because of this Article XI to pay principal of or
interest (including Liquidated Damages) on a Convertible Subordinated Note on
the due date, the failure is still a Default or Event of Default.

     SECTION 11.09. Subordination May Not Be Impaired by Company. No right of
any holder of Senior Debt to enforce the subordination of the indebtedness
evidenced by the Convertible Subordinated Notes shall be impaired by any act or
failure to act by the Company or any holder of Convertible Subordinated Notes or
by the failure of the Company or any such holder to comply with this Indenture.

     SECTION 11.10. Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Senior Debt, the
distribution may be made and the notice given to their Representative.

          Upon any payment or distribution of assets of the Company referred to
in this Article XI, the Trustee and the holders of Convertible Subordinated
Notes shall be entitled to rely upon any order or decree made by any court of
competent jurisdiction or upon any certificate of such Representative or of the
liquidating trustee or agent or other Person making any distribution to the
Trustee or to the holders of Convertible Subordinated Notes 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 XI.

     SECTION 11.11. Rights of Trustee and Paying Agent. Notwithstanding the
provisions of this Article XI or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts that
would prohibit the making of any payment or distribution by the Trustee (other
than pursuant to Section 11.04), and the Trustee may continue to make payments
on the Convertible Subordinated Notes, unless a Trust Officer shall have
received at least two Business Days prior to the date of such payment or
distribution written notice of facts that would cause such payment or
distribution with respect to the Convertible Subordinated Notes to violate this
Article XI. Only the Company or a Representative may give the notice.

          Nothing in this Article XI shall impair the claims of, or payments to,
the Trustee under or pursuant to Section 7.07 hereof.

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

     SECTION 11.12. Authorization to Effect Subordination. Each holder of a
Convertible Subordinated Note by the holder's acceptance thereof authorizes and
directs the Trustee on the holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article XI, and appoints the Trustee to act as the holder's attorney-in-fact for
any and all such purposes. If the Trustee does not

                                                                              57

<PAGE>

file a proper proof of claim or proof of debt in the form required in any
proceeding referred to in Section 6.09 hereof at least 30 days before the
expiration of the time to file such claim, the holders of any Senior Debt or
their Representatives are hereby authorized to file an appropriate claim for and
on behalf of the holders of the Convertible Subordinated Notes.

     SECTION 11.13. Article Applicable to Paying Agents. In case at any time any
Paying Agent other than the Trustee shall have been appointed by the Company and
be then acting hereunder, the term "Trustee" as used in this Article XI shall in
such case (unless the context otherwise requires) be construed as extending to
and including such Paying Agent within its meaning as fully for all intents and
purposes as if such Paying Agent were named in this Article XI in addition to or
in place of the Trustee; provided, however, that the second and third paragraphs
of Section 11.11 shall not apply to the Company or any Subsidiary of the Company
if it or such Subsidiary acts as Paying Agent.

     SECTION 11.14. Senior Debt Entitled to Rely. The holders of Senior Debt
shall have the right to rely upon this Article XI, and no amendment or
modification of the provisions contained herein shall diminish the rights of
such holders unless such holders shall have agreed in writing thereto.

     SECTION 11.15. Permitted Payments. Notwithstanding anything to the contrary
in this Article XI, the holders of Convertible Subordinated Notes may receive
and retain at any time on or prior to the Maturity Date (i) securities that are
subordinated to at least the same extent as the Convertible Subordinated Notes
to (a) Senior Debt and (b) any securities issued in exchange for Senior Debt and
(ii) payments and other distributions made from any trust created pursuant to
Section 8.01 hereof.

                                   ARTICLE XII

                  CONVERSION OF CONVERTIBLE SUBORDINATED NOTES

     SECTION 12.01. Right to Convert. Subject to and upon compliance with the
provisions of this Indenture, each holder of Convertible Subordinated Notes
shall have the right, at his or her option, at any time on or before the close
of business on the last trading day prior to the Maturity Date (except that, (a)
with respect to any Convertible Subordinated Note or portion thereof which is
called for redemption prior to such date, such right shall terminate, except as
provided in the fourth paragraph of Section 12.02, before the close of business
on the last trading day preceding the Redemption Date (unless the Company
defaults in payment of the Redemption Price in which case the conversion right
will terminate at the close of business on the trading day preceding the date
such default is cured) and (b) with respect to any Convertible Subordinated Note
or portion thereof subject to a duly completed election for repurchase, such
right shall terminate on or before the close of business on the Designated Event
Offer Termination Date (unless the Company defaults in the payment due upon
repurchase or such holder elects to withdraw the submission of such election to
repurchase)) to convert the principal

                                                                              58

<PAGE>

amount of any Convertible Subordinated Note held by such holder, or any portion
of such principal amount which is $1,000 or an integral multiple thereof, into
that number of fully paid and non-assessable shares of Common Stock (as such
shares shall then be constituted) obtained by dividing the principal amount of
the Convertible Subordinated Note or portion thereof to be converted by the
Conversion Price in effect at such time, by surrender of the Convertible
Subordinated Note so to be converted in whole or in part in the manner provided
in Section 12.02. A holder of Convertible Subordinated Notes is not entitled to
any rights of a holder of Common Stock until such holder of Convertible
Subordinated Notes has converted his or her Convertible Subordinated Notes to
Common Stock, and only to the extent such Convertible Subordinated Notes are
deemed to have been converted to Common Stock under this Article XII.

     SECTION 12.02. Exercise of Conversion Privilege; Issuance of Common Stock
on Conversion; No Adjustment for Interest or Dividends. To exercise, in whole or
in part, the conversion privilege with respect to any Convertible Subordinated
Note, the holder of such Convertible Subordinated Note shall surrender such
Convertible Subordinated Note, duly endorsed, at an office or agency maintained
by the Company pursuant to Section 4.04, accompanied by the funds, if any,
required by the penultimate paragraph of this Section 12.02, and shall give
written notice of conversion in the form provided on the Convertible
Subordinated Notes (or such other notice which is acceptable to the Company) to
the office or agency that the holder of Convertible Subordinated Notes elects to
convert such Convertible Subordinated Note or such portion thereof specified in
said notice. Such notice shall also state the name or names (with address or
addresses) in which the certificate or certificates for shares of Common Stock
which are issuable on such conversion shall be issued, and shall be accompanied
by transfer taxes, if required pursuant to Section 12.07. Each such Convertible
Subordinated Note surrendered for conversion shall, unless the shares issuable
on conversion are to be issued in the same name as the registration of such
Convertible Subordinated Note, be duly endorsed by, or be accompanied by
instruments of transfer in form satisfactory to the Company duly executed by,
the holder of Convertible Subordinated Notes or his or her duly authorized
attorney.

          As promptly as practicable after satisfaction of the requirements for
conversion set forth above, the Company shall issue and shall deliver to such
holder at the office or agency maintained by the Company for such purpose
pursuant to Section 4.04, a certificate or certificates for the number of full
shares of Common Stock issuable upon the conversion of such Convertible
Subordinated Note or portion thereof in accordance with the provisions of this
Article XII and a check or cash in respect of any fractional interest in respect
of a share of Common Stock arising upon such conversion, as provided in Section
12.03 (which payment, if any, shall be paid no later than five Business Days
after satisfaction of the requirements for conversion set forth above).
Certificates representing shares of Common Stock will not be issued or delivered
unless all taxes and duties, if any, payable by the holder have been paid. In
case any Convertible Subordinated Note of a denomination of an integral multiple
greater than $1,000 is surrendered for partial conversion, and subject to
Section 2.02, the Company

                                                                              59

<PAGE>

shall execute, and the Trustee shall authenticate and deliver to the holder of
the Convertible Subordinated Note so surrendered, without charge to him or her,
a new Convertible Subordinated Note or Convertible Subordinated Notes in
authorized denominations in an aggregate principal amount equal to the
unconverted portion of the surrendered Convertible Subordinated Note.

          Each conversion shall be deemed to have been effected as to any such
Convertible Subordinated Note (or portion thereof) on the date on which the
requirements set forth above in this Section 12.02 have been satisfied as to
such Convertible Subordinated Note (or portion thereof), and the Person in whose
name any certificate or certificates for shares of Common Stock are issuable
upon such conversion shall be deemed to have become on said date the holder of
record of the shares represented thereby; provided, however, that any such
surrender on any date when the Company's stock transfer books are closed shall
constitute the Person in whose name the certificates are to be issued as the
record holder thereof for all purposes on the next succeeding day on which such
stock transfer books are open, but such conversion shall be at the Conversion
Price in effect on the date upon which such Convertible Subordinated Note is
surrendered.

          Any Convertible Subordinated Note or portion thereof surrendered for
conversion during the period from the close of business on the Regular Record
Date for any interest payment through the close of business on the last trading
day immediately preceding such Interest Payment Date shall (unless such
Convertible Subordinated Note or portion thereof being converted has been called
for redemption pursuant to a notice of redemption mailed by the Company to the
holders in accordance with the provisions of Section 3.04) be accompanied by
payment, in funds acceptable to the Company, of an amount equal to the interest
and Liquidated Damages, if any, otherwise payable on such Interest Payment Date
on the principal amount being converted; provided however, that no such payment
need be made if there exists at the time of conversion a default in the payment
of interest or Liquidated Damages, if applicable, on the Convertible
Subordinated Notes. An amount equal to such payment shall be paid by the Company
on such Interest Payment Date to the holder of such Convertible Subordinated
Note at the close of business on such Regular Record Date; provided, however,
that if the Company defaults in the payment of interest or Liquidated Damages,
if applicable, on such Interest Payment Date, such amount shall be paid to the
Person who made such required payment. Except as provided above in this Section
12.02, no adjustment shall be made for interest accrued and Liquidated Damages,
if any, on any Convertible Subordinated Note converted or for dividends on any
shares issued upon the conversion of such Convertible Subordinated Note as
provided in this Article XII.

     SECTION 12.03. Cash Payments in Lieu of Fractional Shares. No fractional
shares of Common Stock or scrip representing fractional shares shall be issued
upon conversion of Convertible Subordinated Notes. If more than one Convertible
Subordinated Note shall be surrendered for conversion at one time by the same
holder, the number of full shares which shall be issuable upon conversion shall
be computed on the basis of the aggregate principal amount of the Convertible
Subordinated Notes (or

                                                                              60

<PAGE>

specified portions thereof to the extent permitted hereby) so surrendered for
conversion. If any fractional share of stock otherwise would be issuable upon
the conversion of any Convertible Subordinated Note or Convertible Subordinated
Notes, the Company shall make an adjustment therefore in cash based upon the
Current Market Price (as defined in Section 12.05(g)) of the Common Stock on the
last trading day prior to the date of conversion.

     SECTION 12.04. Conversion Price. The conversion price shall be as specified
in the form of Convertible Subordinated Note attached as Exhibit A hereto,
subject to adjustment as provided in this Article XII.

     SECTION 12.05. Adjustment of Conversion Price. The Conversion Price shall
be adjusted from time to time by the Company as follows:

          (a) If the Company shall hereafter pay a dividend or make a
     distribution to all holders of the outstanding Common Stock in shares of
     Common Stock, the Conversion Price in effect at the opening of business on
     the date following the Record Date (as defined in Section 12.05(g)) fixed
     for the determination of stockholders entitled to receive such dividend or
     other distribution shall be reduced by multiplying such Conversion Price by
     a fraction of which the numerator shall be the number of shares of Common
     Stock outstanding at the close of business on the Record Date fixed for
     such determination and the denominator shall be the sum of such number of
     shares and the total number of shares constituting such dividend or other
     distribution, such reduction to become effective immediately after the
     opening of business on the day following the Record Date. If any dividend
     or distribution of the type described in this Section 12.05(a) is declared
     but not so paid or made, the Conversion Price shall again be adjusted to
     the Conversion Price which would then be in effect if such dividend or
     distribution had not been declared.

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

          (c) If the Company shall issue rights or warrants to all or
     substantially all holders of its outstanding shares of Common Stock
     entitling them to subscribe for or purchase shares of Common Stock at a
     price per share less than the Current Market Price (as defined in Section
     12.05(g)) on the Record Date fixed for the

                                                                              61

<PAGE>

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

          (d) If the Company shall, by dividend or otherwise, distribute to all
     holders of its Common Stock shares of any class of capital stock of the
     Company (other than any dividends or distributions to which Section
     12.05(a) applies) or evidences of its indebtedness, cash or other assets
     (including securities, but excluding (i) any rights or warrants of a type
     referred to in Section 12.05(c) and (ii) dividends and distributions paid
     exclusively in cash) (the foregoing hereinafter in this Section 12.05(d)
     called the "Securities"), then, in each such case, the Conversion Price
     shall be reduced so that the same shall be equal to the price determined by
     multiplying the Conversion Price in effect immediately prior to the close
     of business on the Record Date (as defined in Section 12.05(g)) with
     respect to such distribution by a fraction of which the numerator shall be
     the Current Market Price (determined as provided in Section 12.05(g)) on
     such date less the fair market value (as determined in good faith by the
     Board of Directors, whose determination shall be conclusive and described
     in a resolution of the Board of Directors) on such date of the portion of
     the Securities so distributed applicable to

                                                                              62

<PAGE>

     one share of Common Stock and the denominator shall be such Current Market
     Price, such reduction to become effective immediately prior to the opening
     of business on the day following the Record Date; provided, however, that
     in the event the then fair market value (as so determined) of the portion
     of the Securities so distributed applicable to one share of Common Stock is
     equal to or greater than the Current Market Price on the Record Date, in
     lieu of the foregoing adjustment, adequate provision shall be made so that
     each holder of Convertible Subordinated Notes shall have the right to
     receive upon conversion of a Convertible Subordinated Note (or any portion
     thereof) the amount of Securities such holder would have received had such
     holder converted such Convertible Subordinated Note (or portion thereof)
     immediately prior to such Record Date. If such dividend or distribution is
     not so paid or made, the Conversion Price shall again be adjusted to be the
     Conversion Price which would then be in effect if such dividend or
     distribution had not been declared. If the Board of Directors determines
     the fair market value of any distribution for purposes of this Section
     12.05(d) by reference to the actual or when issued trading market for any
     securities comprising all or part of such distribution, it must in doing so
     consider the prices in such market over the same period used in computing
     the Current Market Price pursuant to Section 12.05(g) to the extent
     possible.

          Notwithstanding any other provision of this Section 12.05(d) to the
     contrary, rights, warrants, evidences of indebtedness, other securities,
     cash or other assets (including, without limitation, any rights distributed
     pursuant to any stockholder rights plan) shall be deemed not to have been
     distributed for purposes of this Section 12.05(d) if the Company makes
     proper provision so that each holder of Convertible Subordinated Notes who
     converts a Convertible Subordinated Note (or any portion thereof) after the
     Record Date fixed for determination of stockholders entitled to receive
     such distribution shall be entitled to receive upon such conversion, in
     addition to the shares of Common Stock issuable upon such conversion, the
     amount and kind of such distributions that such holder would have been
     entitled to receive if such holder had, immediately prior to such
     determination date, converted such Convertible Subordinated Note into
     Common Stock.

          Rights or warrants distributed by the Company to all holders of Common
     Stock entitling the holders thereof to subscribe for or purchase shares of
     the Company's capital stock (either initially or under certain
     circumstances), which rights or warrants, until the occurrence of a
     specified event or events ("Trigger Event"): (i) are deemed to be
     transferred with such shares of Common Stock; (ii) are not exercisable; and
     (iii) are also issued in respect of future issuances of Common Stock, shall
     be deemed not to have been distributed for purposes of this Section
     12.05(d) (and no adjustment to the Conversion Price under this Section
     12.05(d) shall be required) until the occurrence of the earliest Trigger
     Event, whereupon such rights and warrants shall be deemed to have been
     distributed and an appropriate adjustment to the Conversion Price under
     this Section 12.05(d)

                                                                              63

<PAGE>

     shall be made. If any such rights or warrants, including any such existing
     rights or warrants distributed prior to the Issue Date, are subject to
     subsequent events, upon the occurrence of each of which such rights or
     warrants shall become exercisable to purchase different securities,
     evidences of indebtedness or other assets, then the occurrence of each such
     event shall be deemed to be such date of issuance and Record Date with
     respect to new rights or warrants (and a termination or expiration of the
     existing rights or warrants without exercise by the holder thereof). In
     addition, in the event of any distribution (or deemed distribution) of
     rights or warrants, or any Trigger Event with respect thereto, that was
     counted for purposes of calculating a distribution amount for which an
     adjustment to the Conversion Price under this Section 12.05 was made, (1)
     in the case of any such rights or warrants which shall all have been
     redeemed or repurchased without exercise by any holders thereof, the
     Conversion Price shall be readjusted upon such final redemption or
     repurchase to give effect to such distribution or Trigger Event, as the
     case may be, as though it were a cash distribution, equal to the per share
     redemption or repurchase price received by a holder or holders of Common
     Stock with respect to such rights or warrants (assuming such holder had
     retained such rights or warrants), made to all holders of Common Stock as
     of the date of such redemption or repurchase, and (2) in the case of such
     rights or warrants which shall have expired or been terminated without
     exercise by any holders thereof, the Conversion Price shall be readjusted
     as if such rights and warrants had not been issued.

          For purposes of this Section 12.05(d) and Sections 12.05(a) and (c),
     any dividend or distribution to which this Section 12.05(d) is applicable
     that also includes shares of Common Stock, or rights or warrants to
     subscribe for or purchase shares of Common Stock to which Section 12.05(c)
     applies (or both), shall be deemed instead to be (1) a dividend or
     distribution of the evidences of indebtedness, assets, shares of capital
     stock, rights or warrants other than such shares of Common Stock or rights
     or warrants to which Section 12.05(c) applies (and any Conversion Price
     reduction required by this Section 12.05(d) with respect to such dividend
     or distribution shall then be made) immediately followed by (2) a dividend
     or distribution of such shares of Common Stock or such rights or warrants
     (and any further Conversion Price reduction required by Sections 12.05(a)
     and (c) with respect to such dividend or distribution shall then be made,
     except that (A) the Record Date of such dividend or distribution shall be
     substituted as "the Record Date fixed for the determination of stockholders
     entitled to receive such dividend or other distribution", "Record Date
     fixed for such determination" and "Record Date" within the meaning of
     Section 12.05(a) and as "the Record Date fixed for the determination of
     stockholders entitled to receive such rights or warrants", "the Record Date
     fixed for the determination of the stockholders entitled to receive such
     rights or warrants" and "such Record Date" within the meaning of Section
     12.05(c) and (B) any shares of Common Stock included in such dividend or
     distribution shall not be deemed "outstanding

                                                                              64

<PAGE>

     at the close of business on the date fixed for such determination" within
     the meaning of Section 12.05(a)).

          (e) If the Company shall, by dividend or otherwise, distribute (a
     "Triggering Distribution") cash to all holders of its Common Stock
     (excluding any cash that is distributed upon a merger or consolidation to
     which Section 12.06 applies or as part of a distribution referred to in
     Section 12.05(d)) the Conversion Price shall be reduced so that the same
     shall equal the price determined by multiplying the Conversion Price in
     effect immediately prior to the close of business on the record date for
     such Triggering Distribution (a "Distribution Determination Date") by a
     fraction (i) the numerator of which shall be equal to the Current Market
     Price per share of Common Stock on such Distribution Determination Date
     less the amount of such cash dividend or distribution applicable to one
     share of Common Stock (determined on the basis of the number of shares of
     Common Stock outstanding at the close of business on the Distribution
     Determination Date) and (ii) the denominator of which shall be equal to the
     Current Market Price per share of Common Stock on such Distribution
     Determination Date; provided, however, that if the portion of the cash so
     distributed applicable to one share of Common Stock is equal to or greater
     than the Current Market Price of the Common Stock on the Distribution
     Determination Date, in lieu of the foregoing adjustment, adequate provision
     shall be made so that each holder of Convertible Subordinated Notes shall
     have the right to receive upon conversion of a Convertible Subordinated
     Note (or any portion thereof) the amount of cash such holder would have
     received had such holder converted such Convertible Subordinated Note (or
     portion thereof) immediately prior to such Distribution Determination Date.
     If such dividend or distribution is not so paid or made, the Conversion
     Price shall again be adjusted to be the Conversion Price which would then
     be in effect if such dividend or distribution had not been declared. Any
     cash distribution to all holders of Common Stock as to which the Company
     makes the election permitted by Section 12.05(m) and as to which the
     Company has complied with the requirements of such Section shall be treated
     as not having been made for all purposes of this Section 12.05(e).

          (f) If a tender offer made by the Company or any of its subsidiaries
     for all or any portion of the Common Stock expires and such tender offer
     (as amended upon the expiration thereof) requires the payment to
     stockholders (based on the acceptance (up to any maximum specified in the
     terms of the tender offer) of Purchased Shares (as defined below)) of an
     aggregate consideration having a fair market value (as determined in good
     faith by the Board of Directors, whose determination shall be conclusive
     and described in a resolution of the Board of Directors) that exceeds the
     Current Market Price per share of Common Stock on the trading day next
     succeeding the last date (the "Expiration Date") tenders could have been
     made pursuant to such tender offer (as it may be amended) (the last time at
     which such tenders could have been made on the Expiration Date is
     hereinafter called the "Expiration Time"), then the Conversion Price shall
     be

                                                                              65

<PAGE>

     adjusted so that the same shall equal the price determined by multiplying
     the Conversion Price in effect immediately prior to close of business on
     the date of the Expiration Time by a fraction of which the numerator shall
     be the number of shares of Common Stock outstanding (including any
     Purchased Shares) on the Expiration Time multiplied by the Current Market
     Price of the Common Stock on the trading day next succeeding the Expiration
     Time and the denominator shall be the sum of (x) the fair market value
     (determined as aforesaid) of the aggregate consideration payable to
     stockholders based on the acceptance (up to any maximum specified in the
     terms of the tender offer) of all shares validly tendered and not withdrawn
     as of the Expiration Time (the shares deemed so accepted, up to any such
     maximum, being referred to as the "Purchased Shares") and (y) the product
     of the number of shares of Common Stock outstanding (less any Purchased
     Shares) on the Expiration Time and the Current Market Price of the Common
     Stock on the Trading Day next succeeding the Expiration Time, such
     reduction (if any) to become effective immediately prior to the opening of
     business on the day following the Expiration Time. If the Company is
     obligated to purchase shares pursuant to any such tender offer, but the
     Company is permanently prevented by applicable law from effecting any such
     purchases or all such purchases are rescinded, the Conversion Price shall
     again be adjusted to be the Conversion Price which would then be in effect
     if such tender offer had not been made. If the application of this Section
     12.05(f) to any tender offer would result in an increase in the Conversion
     Price, no adjustment shall be made for such tender offer under this Section
     12.05(f).

          (g) For purposes of this Section 12.05, the following terms shall have
     the meaning indicated:

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

                    (2) "Current Market Price" means the average of the daily
     Closing Prices per share of Common Stock for the 10 consecutive trading

                                                                              66

<PAGE>

     days immediately prior to the date in question; provided, however, that (1)
     if the "ex" date (as hereinafter defined) for any event (other than the
     issuance or distribution requiring such computation) that requires an
     adjustment to the Conversion Price pursuant to Sections 12.05(a), (b), (c),
     (d), (e) or (f) occurs during such 10 consecutive trading days, the Closing
     Price for each trading day prior to the "ex" date for such other event
     shall be adjusted by multiplying such Closing Price by the same fraction by
     which the Conversion Price is so required to be adjusted as a result of
     such other event, (2) if the "ex" date for any event (other than the
     issuance or distribution requiring such computation) that requires an
     adjustment to the Conversion Price pursuant to Section 12.05(a), (b), (c),
     (d), (e) or (f) occurs on or after the "ex" date for the issuance or
     distribution requiring such computation and prior to the day in question,
     the Closing Price for each trading day on and after the "ex" date for such
     other event shall be adjusted by multiplying such Closing Price by the
     reciprocal of the fraction by which the Conversion Price is so required to
     be adjusted as a result of such other event, and (3) if the "ex" date for
     the issuance or distribution requiring such computation is prior to the day
     in question, after taking into account any adjustment required pursuant to
     clause (1) or (2) of this proviso, the Closing Price for each trading day
     on or after such "ex" date shall be adjusted by adding thereto the amount
     of any cash and the fair market value (as determined by the Board of
     Directors in a manner consistent with any determination of such value for
     purposes of Sections 12.05(d) or (f), whose determination shall be
     conclusive and described in a resolution of the Board of Directors) of the
     evidences of indebtedness, shares of capital stock or assets being
     distributed applicable to one share of Common Stock as of the close of
     business on the day before such "ex" date. For purposes of any computation
     under Section 12.05(f), the Current Market Price on any date shall be
     deemed to be the average of the daily Closing Prices per share of Common
     Stock for such day and the next two succeeding trading days; provided,
     however, that if the "ex" date for any event (other than the tender offer
     requiring such computation) that requires an adjustment to the Conversion
     Price pursuant to Section 12.05(a), (b), (c), (d), (e) or (f) occurs on or
     after the Expiration Time for the tender or exchange offer requiring such
     computation and prior to the day in question, the Closing Price for each
     trading day on and after the "ex" date for such other event shall be
     adjusted by multiplying such Closing Price by the reciprocal of the
     fraction by which the Conversion Price is so required to be adjusted as a
     result of such other event. For purposes of this paragraph, the term "ex"
     date, (1) when used with respect to any issuance or distribution, means the
     first date on which the Common Stock trades regular way on the relevant
     exchange or in the relevant market from which the Closing Price was
     obtained without the right to receive such issuance or distribution, (2)
     when used with respect to any subdivision or combination of shares of
     Common Stock, means the first date on which the Common Stock trades regular
     way on such exchange or in such market after the time at which such
     subdivision or combination becomes effective, and (3) when used with
     respect to any tender or exchange offer means the first date on which the
     Common Stock trades regular way on such exchange or

                                                                              67

<PAGE>

     in such market after the Expiration Time of such offer. Notwithstanding the
     foregoing, whenever successive adjustments to the Conversion Price are
     called for pursuant to this Section 12.05, such adjustments shall be made
     to the Current Market Price as may be necessary or appropriate to
     effectuate the intent of this Section 12.05 and to avoid unjust or
     inequitable results as determined in good faith by the Board of Directors.

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

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

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

          (h) The Company may make such reductions in the Conversion Price, in
     addition to those required by Sections 12.05(a), (b), (c), (d), (e) and
     (f), as the Board of Directors considers to be advisable to avoid or
     diminish any income tax to holders of Common Stock or rights to purchase
     Common Stock resulting from any dividend or distribution of stock (or
     rights to acquire stock) or from any event treated as such for income tax
     purposes.

          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, if the Board of Directors has made a determination that such
     reduction would be in the Company's best interests, which determination
     shall be conclusive and described in a resolution of the Board of
     Directors. The reduction in Conversion Price shall be irrevocable during
     this period. Whenever the Conversion Price is reduced pursuant to the
     preceding sentence, the Company shall mail to the holders of Convertible
     Subordinated Notes at his or her last address appearing on the Register of
     holders maintained for that purpose a notice of the reduction at least 15
     days prior to the date the reduced Conversion Price takes effect, and such

                                                                              68

<PAGE>

     notice shall state the reduced Conversion Price and the period during which
     it will be in effect.

          (i) No adjustment in the Conversion Price shall be required unless
     such adjustment would require an increase or decrease of at least 1% in
     such price; provided, however, that any adjustments which by reason of this
     Section 12.05(i) are not required to be made shall be carried forward and
     taken into account in any subsequent adjustment. All calculations under
     this Article XII shall be made by the Company and shall be made to the
     nearest cent or to the nearest one hundredth of a share, as the case may
     be.

          No adjustment need be made for a change in the par value or no par
     value of the Common Stock.

          (j) Whenever the Conversion Price is adjusted as herein provided, the
     Company shall promptly file with the Trustee and any Conversion Agent other
     than the Trustee an Officers' Certificate setting forth the Conversion
     Price after such adjustment and setting forth a brief statement of the
     facts requiring such adjustment. Promptly after delivery of such
     certificate, the Company shall prepare a notice of such adjustment of the
     Conversion Price setting forth the adjusted Conversion Price and the date
     on which each adjustment becomes effective and shall mail such notice of
     such adjustment of the Conversion Price to each holder of Convertible
     Subordinated Notes at his or her last address appearing on the Register of
     holders maintained for that purpose within 20 days of the effective date of
     such adjustment. Failure to deliver such notice shall not affect the
     legality or validity of any such adjustment.

          (k) In any case in which this Section 12.05 provides that an
     adjustment shall become effective immediately after a Record Date for an
     event, the Company may defer until the occurrence of such event issuing to
     the holder of any Convertible Subordinated Note converted after such Record
     Date and before the occurrence of such event the additional shares of
     Common Stock issuable upon such conversion by reason of the adjustment
     required by such event over and above the Common Stock issuable upon such
     conversion before giving effect to such adjustment.

          (l) For purposes of this Section 12.05, the number of shares of Common
     Stock at any time outstanding shall not include shares held in the treasury
     of the Company but shall include shares issuable in respect of scrip
     certificates issued in lieu of fractions of shares of Common Stock. The
     Company shall not pay any dividend or make any distribution on shares of
     Common Stock held in the treasury of the Company.

          (m) In lieu of making any adjustment to the Conversion Price pursuant
     to Section 12.05(e), the Company may elect to reserve an amount of cash for
     distribution to the holders of Convertible Subordinated Notes upon the
     conversion

                                                                              69

<PAGE>

     of the Convertible Subordinated Notes so that any such holder converting
     Convertible Subordinated Notes will receive upon such conversion, in
     addition to the shares of Common Stock and other items to which such holder
     is entitled, the full amount of cash which such holder would have received
     if such holder had, immediately prior to the Record Date for such
     distribution of cash, converted its Convertible Subordinated Notes into
     Common Stock, together with any interest accrued with respect to such
     amount, in accordance with this Section 12.05(m). The Company may make such
     election by providing an Officers' Certificate to the Trustee to such
     effect on or prior to the payment date for any such distribution and
     depositing with the Trustee on or prior to such date an amount of cash
     equal to the aggregate amount that the holders of Convertible Subordinated
     Notes would have received if such holders had, immediately prior to the
     Record Date for such distribution, converted all of the Convertible
     Subordinated Notes into Common Stock. Any such funds so deposited by the
     Company with the Trustee shall be invested by the Trustee in U.S.
     Government Obligations with a maturity not more than three (3) months from
     the date of issuance. Upon conversion of Convertible Subordinated Notes by
     a holder thereof, such holder shall be entitled to receive, in addition to
     the Common Stock issuable upon conversion, an amount of cash equal to the
     amount such holder would have received if such holder had, immediately
     prior to the Record Date for such distribution, converted its Convertible
     Subordinated Note into Common Stock, along with such holder's pro-rata
     share of any accrued interest earned as a consequence of the investment of
     such funds. Promptly after making an election pursuant to this Section
     12.05(m), the Company shall give or shall cause to be given notice to all
     holders of Convertible Subordinated Notes of such election, which notice
     shall state the amount of cash per $1,000 principal amount of Convertible
     Subordinated Notes such holders shall be entitled to receive (excluding
     interest) upon conversion of the Convertible Subordinated Notes as a
     consequence of the Company having made such election.

     SECTION 12.06. Effect of Reclassification, Consolidation, Merger or Sale.
If any of the following events occur: (i) any reclassification or change of the
outstanding shares of Common Stock (other than a change in par value, or from
par value to no par value, or from no par value to par value, or as a result of
a subdivision or combination), (ii) any consolidation, merger or combination of
the Company with another corporation as a result of which holders of Common
Stock shall be entitled to receive stock, securities or other property or assets
(including cash) with respect to or in exchange for such Common Stock, or (iii)
any sale or conveyance of the properties and assets of the Company as an
entirety or substantially as an entirety to any other corporation as a result of
which holders of Common Stock shall be entitled to receive stock, securities or
other property or assets (including cash) with respect to or in exchange for
such Common Stock, then the Company or the successor or purchasing corporation,
as the case may be, shall execute with the Trustee a supplemental indenture
(which shall comply with the TIA as in force at the date of execution of such
supplemental indenture if such supplemental indenture is then required to so
comply) providing that the Convertible

                                                                              70

<PAGE>

Subordinated Notes shall be convertible into the kind and amount of shares of
stock and other securities or property or assets (including cash) receivable
upon such reclassification, change, consolidation, merger, combination, sale or
conveyance by a holder of a number of shares of Common Stock issuable upon
conversion of the Convertible Subordinated Notes (assuming, for such purposes, a
sufficient number of authorized shares of Common Stock available to convert all
such Convertible Subordinated Notes) immediately prior to such reclassification,
change, consolidation, merger, combination, sale or conveyance (except that such
holder will not receive the Make Whole Premium (as defined in Section 12.12
below) if such holder does not convert its Convertible Subordinated Notes "in
connection with" the relevant Designated Event that constitutes to a Change of
Control; a conversion of the Convertible Subordinated Notes by a Holder will be
deemed for these purposes to be "in connection with" a Change of Control if the
notice of such conversion is provided in compliance with Article XII to the
Conversion Agent on or subsequent to the date 10 trading days prior to the date
announced by the Company as the anticipated Designated Event Date but before the
close of business on the Business Day immediately preceding the related
Designated Event Payment Date) assuming such holder of Common Stock did not
exercise his or her rights of election, if any, as to the kind or amount of
securities, cash or other property receivable upon such consolidation, merger,
statutory exchange, sale or conveyance (provided that, if the kind or amount of
securities, cash or other property receivable upon such consolidation, merger,
statutory exchange, sale or conveyance is not the same for each share of Common
Stock in respect of which such rights of election have not been exercised
("non-electing share"), then, for the purposes of this Section 12.06, the kind
and amount of securities, cash or other property receivable upon such
consolidation, merger, statutory exchange, sale or conveyance for each
non-electing share shall be deemed to be the kind and amount so receivable per
share by a plurality of the non-electing shares). Such supplemental indenture
shall provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article XII. If, in the case
of any such reclassification, change, consolidation, merger, combination, sale
or conveyance, the stock or other securities and assets receivable thereupon by
a holder of shares of Common Stock includes shares of stock or other securities
and assets of a corporation other than the successor or purchasing corporation,
as the case may be, in such reclassification, change, consolidation, merger,
combination, 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 Convertible Subordinated Notes as
the Board of Directors shall reasonably consider necessary by reason of the
foregoing.

          The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each holder of Convertible Subordinated Notes at his
or her address appearing on the Register of holders for that purpose within 20
days after execution thereof. Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture.

                                                                              71

<PAGE>

          The above provisions of this Section 12.06 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

          If this Section 12.06 applies to any event or occurrence, Section
12.05 shall not apply.

     SECTION 12.07. Taxes on Shares Issued. The issue of stock certificates on
conversions of Convertible Subordinated Notes shall be made without charge to
the converting holder for any tax in respect of the issue thereof. The Company
shall not, however, be required to pay any tax which may be payable in respect
of any transfer involved in the issue and delivery of stock in any name other
than that of the holder of any Convertible Subordinated Note converted, and the
Company shall not be required to issue or deliver any such stock certificate
unless and until the Person or Persons requesting the issue thereof shall have
paid to the Company the amount of such tax or shall have established to the
reasonable satisfaction of the Company that such tax has been paid.

     SECTION 12.08. Reservation of Shares; Shares to Be Fully Paid; Listing of
Common Stock. The Company shall provide, free from preemptive rights, out of its
authorized but unissued shares or shares held in treasury, sufficient shares to
provide for the conversion of the Convertible Subordinated Notes from time to
time as such Convertible Subordinated Notes are presented for conversion.

          Before taking any action which would cause an adjustment reducing the
Conversion Price below the then par value, if any, of the shares of Common Stock
issuable upon conversion of the Convertible Subordinated Notes, the Company
shall take all corporate action which may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue shares of such
Common Stock at such adjusted Conversion Price; provided, however, that no
shares of Common Stock shall be required to be issued at a Conversion Price less
than the par value of such Common Stock.

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

          The Company further covenants that as long as the Common Stock is
quoted on the Nasdaq National Market, or its successor, the Company shall cause
all Common Stock issuable upon conversion of the Convertible Subordinated Notes
to be eligible for such quotation in accordance with, and at the times required
under, the requirements of such market, and if at any time the Common Stock
becomes listed on the New York Stock Exchange or any other national securities
exchange, the Company shall cause all Common Stock issuable upon conversion of
the Convertible Subordinated Notes to be so listed and kept listed.

                                                                              72

<PAGE>

     SECTION 12.09. Responsibility of Trustee. The Trustee shall not at any time
be under any duty of responsibility to any holders of Convertible Subordinated
Notes to determine whether any facts exist which may require any adjustment of
the Conversion Price, or with respect to the nature or extent or calculation of
any such adjustment when made, or with respect to the method employed, or herein
or in any supplemental indenture provided to be employed, in making the same.
The Trustee shall not be accountable with respect to the validity or value (or
the kind or amount) of any shares of Common Stock, or of any securities or
property, which may at any time be issued or delivered upon the conversion of
any Convertible Subordinated Note; and the Trustee makes no representations with
respect thereto. Subject to the provisions of Section 7.01, the Trustee shall
not be responsible for any failure of the Company to issue, transfer or deliver
any shares of Common Stock or stock certificates or other securities or property
or cash upon the surrender of any Convertible Subordinated Note for the purpose
of conversion or to comply with any of the duties, responsibilities or covenants
of the Company contained in this Article XII. Without limiting the generality of
the foregoing, the Trustee shall not have any responsibility to determine the
correctness of any provisions contained in any supplemental indenture entered
into pursuant to Section 12.06 relating either to the kind or amount of shares
of stock or securities or property (including cash) receivable by holders of
Convertible Subordinated Notes upon the conversion of their Convertible
Subordinated Notes after any event referred to in such Section 12.06 or to any
adjustment to be made with respect thereto, but, subject to the provisions of
Section 7.01, may accept as conclusive evidence of the correctness of any such
provisions, and shall be protected in relying upon, the Officers' Certificate
and Opinion of Counsel (which the Company shall be obligated to file with the
Trustee prior to the execution of any such supplemental indenture) with respect
thereto.

     SECTION 12.10. Notice to Holders Prior to Certain Actions. If

          (a) the Company declares a dividend (or any other distribution) on its
     Common Stock (other than in cash out of retained earnings or other than a
     dividend that results in an adjustment in the Conversion Price pursuant to
     Section 12.05 as to which the Company has made an election in accordance
     with Section 12.05(m)); or

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

          (c) there is any reclassification of the Common Stock (other than a
     subdivision or combination of outstanding Common Stock, or a change in par
     value, or from par value to no par value, or from no par value to par
     value), or of any consolidation or merger to which the Company is a party
     and for which approval of any stockholders of the Company is required, or
     of the sale or transfer of all or substantially all of the assets of the
     Company; or

                                                                              73

<PAGE>

          (d) there is any voluntary or involuntary dissolution, liquidation or
     winding-up of the Company;

then the Company shall cause to be filed with the Trustee and to be mailed to
each holder of Convertible Subordinated Notes at his or her address appearing on
the Register maintained for that purpose as promptly as possible but in any
event at least 15 days prior to the applicable date hereinafter specified, a
notice stating (x) the date on which a record is to be taken for the purpose of
such dividend, distribution or rights or warrants, or, if a record is not to be
taken, the date as of which the holders of Common Stock of record to be entitled
to such dividend, distribution or rights are to be determined, or (y) the date
on which such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up is expected to become effective or occur,
and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding-up. Failure to give such notice,
or any defect therein, shall not affect the legality or validity of such
dividend, distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up.

     SECTION 12.11. Restriction on Common Stock Issuable Upon Conversion.

          (a) Shares of Common Stock to be issued upon conversion of Convertible
Subordinated Notes prior to the effectiveness of a Shelf Registration Statement
shall be physically delivered in certificated form to the holders converting
such Securities and the certificate representing such shares of Common Stock
shall bear the Restricted Common Stock Legend unless removed in accordance with
section 12.11(c).

          (b) If (i) shares of Common Stock to be issued upon conversion of a
Convertible Subordinated Note prior to the effectiveness of a Shelf Registration
Statement are to be registered in a name other than that of the holder of such
Convertible Subordinated Note or (ii) shares of Common Stock represented by a
certificate bearing the Restricted Common Stock Legend are transferred
subsequently by such holder, then, unless the Shelf Registration Statement has
become effective and such shares are being transferred pursuant to the Shelf
Registration Statement, the holder must deliver to the transfer agent for the
Common Stock a certificate in substantially the form of Exhibit C as to
compliance with the restrictions on transfer applicable to such shares of Common
Stock and neither the transfer agent nor the registrar for the Common Stock
shall be required to register any transfer of such Common Stock not so
accompanied by a properly completed certificate.

          (c) Except in connection with a Shelf Registration Statement, if
certificates representing shares of Common Stock are issued upon the
registration of transfer, exchange or replacement of any other certificate
representing shares of Common Stock bearing the Restricted Common Stock Legend,
or if a request is made to remove such Restricted Common Stock Legend from
certificates representing shares of Common Stock, the certificates so issued
shall bear the Restricted Common Stock Legend, or the

                                                                              74

<PAGE>

Restricted Common Stock Legend shall not be removed, as the case may be, unless
there is delivered to the Company such satisfactory evidence, which, in the case
of a transfer made pursuant to Rule 144 under the Securities Act, may include an
opinion of counsel pursuant to the laws in the State of New York, as may be
reasonably required by the Company, that neither the legend nor the restrictions
on transfer set forth therein are required to ensure that transfers thereof
comply with the provisions of Rule 144A, Rule 144 or Regulation S under the
Securities Act or that such shares of Common Stock are securities that are not
"restricted" within the meaning of Rule 144 under the Securities Act. Upon
provision to the Company of such reasonably satisfactory evidence, the Company
shall cause the transfer agent for the Common Stock to countersign and deliver
certificates representing shares of Common Stock that do not bear the legend.

     SECTION 12.12. Make Whole Premium Upon a Change of Control.

          If there shall have occurred a Designated Event that constitutes a
Change of Control, the Company shall pay a "Make Whole Premium" to the Holders
of the Convertible Subordinated Notes who convert their Convertible Subordinated
Notes during the period beginning 10 trading days before the anticipated
Designated Event Date and ending at the close of business on the business day
immediately preceding the Designated Event Payment Date by increasing the
Conversion Rate for such Convertible Subordinated Notes. The number of
additional shares of Common Stock per $1,000 principal amount of Convertible
Subordinated Notes constituting the Make Whole Premium shall be determined by
reference to the table below, based on the Designated Event Date and the Stock
Price on such Designated Event Date; provided that if the Stock Price or
Designated Event Date are not set forth on the table: (i) if the actual Stock
Price on the Designated Event Date is between two Stock Prices on the table or
the actual Designated Event Date is between two Designated Event Dates on the
table, the Make Whole Premium will be determined by a straight-line
interpolation between the Make Whole Premiums set forth for the two Stock Prices
and the two Designated Event Dates on the table based on a 365-day year, as
applicable, (ii) if the Stock Price on the Designated Event Date exceeds $17.28
per share, subject to adjustment as set forth herein, no Make Whole Premium will
be paid, and (iii) if the Stock Price on the Designated Event Date is less than
$5.76 per share, subject to adjustment as set forth herein, no Make Whole
Premium will be paid. If Holders of the Common Stock receive only cash in the
Designated Event, the Stock Price shall be the cash amount paid per share of the
Common Stock in connection with the Designated Event. Otherwise, the Stock Price
shall be equal to the average Closing Prices of the Common Stock for each of the
10 trading days immediately preceding, but not including, the applicable
Designated Event Date.

          MAKE WHOLE PREMIUM UPON A DESIGNATED EVENT DATE (NUMBER OF ADDITIONAL
SHARES)

                                                                              75

</TABLE>

          The Stock Prices set forth in the first column of the table above will
be adjusted as of any date on which the Conversion Rate of the Securities is
adjusted. The adjusted Stock Prices will equal the Stock Prices applicable
immediately prior to such adjustment multiplied by a fraction, the numerator of
which is the Conversion Rate immediately prior to the adjustment giving rise to
the Stock Price adjustment and the denominator of which is the Conversion Rate
as so adjusted. The number of additional shares set forth in the table above
will be adjusted in the same manner as the Conversion Rate as set forth in
Section 12.05 hereof, other than as a result of an adjustment of the Conversion
Rate by adding the Make Whole Premium as described above.

          For purposes of giving effect to the Make Whole Premium, the
Conversion Price of the Convertible Subordinated Notes following payment of the
Make Whole Premium shall be equal to the product of (a) the Conversion Price
immediately prior to payment of the Make Whole Premium and (b) the fraction
obtained by dividing (i) the Conversion Rate immediately prior to payment of the
Make Whole Premium by (ii) the Conversion Rate immediately after payment of the
Make Whole Premium.

          Notwithstanding the foregoing paragraphs, in no event will the total
number of shares of Common Stock issuable upon conversion of a Convertible
Subordinated Note exceed 173.6111 per $1,000 principal amount of Convertible
Subordinated Notes, subject to proportional adjustment in the same manner as the
Conversion Price as set forth in clauses (a) through (d) of Section 12.05
hereof.

          By delivering the amount of cash and/or the number of shares of Common
Stock issuable on conversion to the Trustee, the Company will be deemed to have
satisfied its obligation to pay the principal amount of the Convertible
Subordinated Notes so converted and its obligation to pay accrued and unpaid
interest attributable to the period from the most recent Interest Payment Date
through the date of conversion (which amount will be deemed paid in full rather
than cancelled, extinguished or forfeited).

                                                                              76

                             AMKOR TECHNOLOGY, INC.

                  6 1/4% CONVERTIBLE SUBORDINATED NOTE DUE 2013

          1. INTEREST. Amkor Technology, Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Convertible
Subordinated Note at the rate per annum shown above. The Company will pay
interest semi-annually in arrears on June 1 and December 1 of each year,
beginning June 1, 2006. Interest on the Convertible Subordinated Notes will
accrue from the most recent Interest Payment Date to which interest has been
paid or, if no interest has been paid, from November 18, 2005. Interest
(including any Liquidated Damages) will be computed on the basis of a 360-day
year composed of twelve 30-day months.

          2. METHOD OF PAYMENT. The Company will pay interest (and Liquidated
Damages, if any) on the Convertible Subordinated Notes (except defaulted
interest) to the Person in whose name each Convertible Subordinated Note is
registered at the close of business on the May 15 or November 15 immediately
preceding the relevant Interest Payment Date (each a "Regular Record Date")
(other than with respect to a Convertible Subordinated Note or portion thereof
called for redemption on a Redemption Date, or repurchased in connection with a
Designated Event on a repurchase date, during the period from the close of
business on a Regular Record Date to (but excluding) the next succeeding
Interest Payment Date, in which case accrued interest (and Liquidated Damages,
if any) shall be payable (unless such Convertible Subordinated Note or portion
thereof is converted) to the holder of the Convertible Subordinated Note or
portion thereof redeemed or repurchased in accordance with the applicable
redemption or repurchase provisions of the Indenture). Holder must surrender
Convertible Subordinated Notes to a Paying Agent to collect principal payments.
The Company will pay the principal of, premium, if any, and interest (including
Liquidated Damages, if any) on the Convertible Subordinated Notes at the office
or agency of the Company maintained for such purpose, in money of the United
States that at the time of payment is legal tender for payment of public and
private debts. Until otherwise designated by the Company, the Company's office
or agency maintained for such purpose will be the principal Corporate Trust
Office of the Trustee (as defined below). However, the Company may pay
principal, premium, if any, and interest (including Liquidated Damages, if any)
by check payable in such money, and may mail such check to the holders of the
Convertible Subordinated Notes at their respective addresses as set forth in the
Register of holders of Convertible Subordinated Notes.

          3. PAYING AGENT AND REGISTRAR. U.S. Bank National Association
(together with any successor Trustee under the Indenture referred to below, the
"Trustee"), will act as Paying Agent and Registrar. The Company may change the
Paying Agent, Registrar or co-registrar without prior notice. Subject to certain
limitations in the Indenture, the Company or any of its subsidiaries may act in
any such capacity.

                                                                             A-5

<PAGE>

          4. INDENTURE. The Company issued the Convertible Subordinated Notes
under an Indenture dated as of November 18, 2005 (the "Indenture") between the
Company and the Trustee. The terms of the Convertible Subordinated Notes include
those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the
"TIA") as in effect on the Issue Date. The Convertible Subordinated Notes are
subject to, and qualified by, all such terms, certain of which are summarized
hereon, and holders are referred to the Indenture and the TIA for a statement of
such terms. However, to the extent any provision of any Convertible Subordinated
Note conflicts with the express provisions of this Indenture, the provisions of
this Indenture shall govern and be controlling. The Convertible Subordinated
Notes are unsecured general obligations of the Company limited to (except as
otherwise provided in the Indenture) up to $100,000,000 in aggregate principal
amount. Capitalized terms not defined below have the same meaning as is given to
them in the Indenture.

          5. OPTIONAL REDEMPTION. On or after December 5, 2010, the Company
shall have the option to redeem the Convertible Subordinated Notes, in whole or
from time to time in part, at the following Redemption Prices (expressed as
percentages of principal amount), if redeemed during the twelve month period
beginning December 1 of each year indicated (December 5, 2010 through November
30, 2010, in the case of the first such year) plus accrued and unpaid interest
(and Liquidated Damages, if any) to, but excluding, the Redemption Date:

<TABLE>
<CAPTION>
YEAR      REDEMPTION PRICE
----      ----------------
<S>       <C>
2010...       102.344%
2011...       101.563%
2012...       100.781%
</TABLE>

and 100% at December 1, 2013.

          Notice of redemption will be mailed by first class mail at least 15
days but not more than 60 days before the Redemption Date to each holder of
Convertible Subordinated Notes to be redeemed at his or her registered address.
Convertible Subordinated Notes in denominations larger than $1,000 may be
redeemed in part but only in integral multiples of $1,000. If less than all the
Convertible Subordinated Notes are to be redeemed, the Trustee shall select the
Convertible Subordinated Notes to be redeemed by a method that complies with the
requirements of the principal national securities exchange, if any, on which the
Convertible Subordinated Notes are listed or quoted, or, if the Convertible
Subordinated Notes are not so listed, on a pro rata basis by lot or by any other
method that the Trustee considers fair and appropriate. On and after the
Redemption Date, interest (and Liquidated Damages, if any) ceases to accrue on
Convertible Subordinated Notes or portions thereof called for redemption (unless
the Company defaults in the payment of the Redemption Price). If this
Convertible Subordinated Note is redeemed on a date which is also an Interest
Payment Date, the interest payment (and Liquidated Damages, if any) due on such
Interest Payment Date

                                                                             A-6

<PAGE>

will be paid to the Person in whose name this Convertible Subordinated Note is
registered at the close of business on such Regular Record Date.

          6. DESIGNATED EVENT. Upon a Designated Event, the Company shall make a
Designated Event Offer to repurchase all outstanding Convertible Subordinated
Notes at a price equal to 100% of the aggregate principal amount of the
Convertible Subordinated Notes, plus accrued and unpaid interest (and Liquidated
Damages, if any) to, but excluding, the date of repurchase, such offer to be
made as provided in the Indenture. To accept the Designated Event Offer, the
holder hereof must comply with the terms thereof, including surrendering this
Convertible Subordinated Note, with the "Option of Holder to Elect Repurchase"
portion hereof completed, to the Company, a depositary, if appointed by the
Company, or a Paying Agent, at the address specified in the notice of the
Designated Event Offer mailed to holders as provided in the Indenture, prior to
termination of the Designated Event Offer.

          If there shall occur a Designated Event that constitutes a Change of
Control, the Company shall pay a "Make Whole Premium" in certain circumstances
as described in the Indenture.

          7. SUBORDINATION. The Company's payment of the principal of, premium,
if any, and interest (including Liquidated Damages, if any) on the Convertible
Subordinated Notes is subordinated to the prior payment in full of the Company's
Senior Debt as set forth in the Indenture. Each holder of Convertible
Subordinated Notes by his or her acceptance hereof covenants and agrees that all
payments of the principal of, premium, if any, and interest (including
Liquidated Damages, if any) on the Convertible Subordinated Notes by the Company
shall be subordinated in accordance with the provisions of Article XI of the
Indenture, and each holder of Convertible Subordinated Notes accepts and agrees
to be bound by such provisions. The Company agrees, and each holder of
Convertible Subordinated Notes by accepting a Convertible Subordinated Note
agrees, that the indebtedness evidenced by the Convertible Subordinated Note is
pari passu in right of payment to the Existing Convertible Subordinated Notes.

          8. DENOMINATIONS, TRANSFER, EXCHANGE. The Convertible Subordinated
Notes are in registered form without coupons in denominations of $1,000 and
integral multiples of $1,000. The transfer of Convertible Subordinated Notes may
be registered and Convertible Subordinated Notes may be exchanged as provided in
the Indenture. As a condition of transfer, the Registrar and the Trustee may
require a holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company or the Registrar
need not exchange or register the transfer of any Convertible Subordinated Note
or portion of a Convertible Subordinated Note selected for redemption or
submitted for repurchase. Also, the Company or the Registrar need not exchange
or register the transfer of any Convertible Subordinated Note for a period of 15
days before a selection of Convertible Subordinated Notes to be redeemed.

                                                                             A-7

          9. PERSONS DEEMED OWNERS. The registered holder of a Convertible
Subordinated Note may be treated as its owner for all purposes.

          10. AMENDMENTS AND WAIVERS. Subject to certain exceptions, the Company
and the Trustee may amend the Indenture or the Convertible Subordinated Notes
with the written consent of the holders of at least a majority in principal
amount of the then outstanding Convertible Subordinated Notes (including
consents obtained in connection with tender offer or exchange offer for
Convertible Subordinated 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 Subordinated Notes.

          Without the consent of any holder of a Convertible Subordinated Note,
the Indenture or the Convertible Subordinated Notes may be amended by the
Company and the Trustee to: (a) cure any ambiguity or correct or supplement any
defective or inconsistent provision contained in the Indenture, or make any
other changes in the provisions of the Indenture which the Company and the
Trustee may deem necessary or desirable provided such amendment does not
materially and adversely affect the legal rights under the Indenture of the
holders of Convertible Subordinated Notes; (b) provide for uncertificated
Convertible Subordinated Notes in addition to or in place of certificated
Convertible Subordinated Notes; (c) evidence the succession of another Person to
the Company and providing for the assumption by such successor of the covenants
and obligations of the Company thereunder and in the Convertible Subordinated
Notes as permitted by Section 5.01 of the Indenture; (d) provide for conversion
rights and/or repurchase rights of holders of Convertible Subordinated Notes in
the event of consolidation, merger or sale of all or substantially all of the
assets of the Company as required to comply with Sections 5.01 and/or 12.06 of
the Indenture; (e) reduce the Conversion Price; (f) make any change that would
provide any additional rights or benefits to the holders of Convertible
Subordinated Notes or that does not adversely affect the legal rights under the
Indenture of any such holder; or (g) comply with the requirements of the
Commission in order to effect or maintain the qualification of the Indenture
under the TIA.

          Without the consent of each holder affected, an amendment or waiver
may not (with respect to any Convertible Subordinated Notes held by a
non-consenting holder): (a) reduce the principal amount of Convertible
Subordinated Notes whose holders must consent to an amendment, supplement or
waiver; (b) reduce the principal of, or premium on, or change the fixed maturity
of any Convertible Subordinated Note or, except as permitted pursuant to clause
(a) of the immediately preceding paragraph, alter the provisions with respect to
the redemption of the Convertible Subordinated Notes; (c) reduce the rate of or
change the time for payment of interest, including defaulted interest or
Liquidated Damages on any Convertible Subordinated Notes; (d) waive a Default or
Event of Default in the payment of principal of or premium, if any, or interest

of acceleration of the Convertible Subordinated Notes by the holders of at least
a majority in aggregate principal amount of the Convertible Subordinated Notes
and a waiver of the payment default that resulted from such acceleration); (e)
make the principal of, or

                                                                             A-8

<PAGE>

premium, if any, or interest or Liquidated Damages on, any Convertible
Subordinated Note payable in money other than as provided for in the Indenture
and in the Convertible Subordinated Notes; (f) make any change in the provisions
of the Indenture relating to waivers of past Defaults or the rights of holders
of Convertible Subordinated Notes to receive payments of principal of, premium,
if any, or interest or Liquidated Damages on the Convertible Subordinated Notes;
(g) waive a redemption payment with respect to any Convertible Subordinated
Note; (h) make any change in the foregoing amendment and waiver provisions, or
(i) except as permitted by the Indenture (including Section 9.01(a)), increase
the Conversion Price or modify the provisions of the Indenture relating to
conversion of the Convertible Subordinated Notes in a manner adverse to the
holders thereof. In addition, any amendment to the provisions of Article XI of
the Indenture (which relate to subordination) will require the consent of the
holders of at least 75% in aggregate principal amount of the Convertible
Subordinated Notes then outstanding if such amendment would adversely affect the
rights of holders of Convertible Subordinated Notes.

          11. DEFAULTS AND REMEDIES. An Event of Default is: (a) default in

Notes, when due at maturity, upon repurchase, upon acceleration or otherwise,
whether or not such payment is prohibited by the subordination provisions of the
Indenture; (b) default for 30 days or more in payment of any installment of
interest or Liquidated Damages on the Convertible Subordinated Notes, whether or
not such payment is prohibited by the subordination provisions of the Indenture;
(c) default by the Company for 60 days or more after notice in the observance or
performance of any other covenants in the Indenture; (d) default in the payment
of the Designated Event Payment in respect of the Convertible Subordinated Notes
on the date therefore, whether or not such payment is prohibited by the
subordination provisions of the Indenture; (e) failure to provide timely notice
of a Designated Event; (f) failure of the Company or any Material Subsidiary to
make any payment at maturity, including any applicable grace period, in respect
of indebtedness for borrowed money of, or guaranteed or assumed by, the Company
or any Material Subsidiary which payment is in an amount in excess of
$20,000,000 and continuance of such failure for 30 days after notice; (g)
default by the Company or any Material Subsidiary with respect to any such
indebtedness, which default results in the acceleration of such indebtedness of
an amount in excess of $20,000,000 without such indebtedness having been paid or
discharged or such acceleration having been cured, waived, rescinded, or
annulled for 30 days after notice; or (h) certain events involving bankruptcy,
insolvency or reorganization of the Company or any Material Subsidiary. If an
Event of Default occurs and is continuing, the Trustee or the holders of at
least 25% in principal amount of the then outstanding Convertible Subordinated
Notes may declare the unpaid principal of, premium, if any, and accrued and
unpaid interest and Liquidated Damages, if any, on all Convertible Subordinated
Notes then outstanding to be due and payable immediately, except that in the
case of an Event of Default arising from certain events of bankruptcy,
insolvency, or reorganization with respect to the Company all outstanding
Convertible Subordinated Notes become due and payable without further action or
notice. Holders of Convertible Subordinated Notes may not enforce the

                                                                             A-9

<PAGE>

Indenture or the Convertible Subordinated Notes except as provided in the
Indenture. The Trustee may require an indemnity satisfactory to it before it
enforces the Indenture or the Convertible Subordinated Notes. Subject to certain
limitations, holders of a majority in principal amount of the then outstanding
Convertible Subordinated Notes may direct the Trustee in its exercise of any
trust or power. The Trustee may withhold from holders notice of any continuing
default (except a default in payment of principal, premium, if any, or interest
or Liquidated Damages, if applicable) if it determines that withholding notice
is in their interests. The Company must furnish annual compliance certificates
to the Trustee.

          12. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee or any of its
Affiliates, in their individual or any other capacities, may make or continue
loans to or guaranteed by, accept deposits from and perform services for the
Company or its Affiliates and may otherwise deal with the Company or its
Affiliates as if it were not Trustee.

          13. NO RECOURSE AGAINST OTHERS. No director, officer, employee or
stockholder, as such, of the Company shall have any liability for any
obligations of the Company under the Convertible Subordinated 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
Subordinated Note waives and releases all such liability. The waiver and release
are part of the consideration for the Convertible Subordinated Notes.

          14. AUTHENTICATION. This Convertible Subordinated Note shall not be
valid until authenticated by the manual signature of the Trustee or an
authenticating agent.

          15. ABBREVIATIONS. Customary abbreviations may be used in the name of

of business on the last trading day preceding the Redemption Date (unless the
Company defaults in payment of the Redemption Price in which case the conversion
right will terminate at the close of business on the trading day preceding the
date such default is cured) or (b) subject to a duly completed election for
repurchase, on or before the close of business on the Designated Event Offer
Termination Date (unless the Company defaults in payment due upon repurchase or

non-assessable shares of common stock of the Company ("Common Stock") obtained
by dividing the principal amount of the Convertible Subordinated Note or portion
thereof to be converted by the conversion price of $7.49 per share, as adjusted
from time to time as provided in the Indenture, including with respect to the
Make Whole Premium (the "Conversion Price"), upon surrender of this Convertible
Subordinated Note to the Company at the office or agency maintained for such

the Company), accompanied by written notice of conversion duly executed (and if
the shares of Common Stock to be issued on conversion are to be issued in any
name other than that of the registered holder of this Convertible Subordinated
Note by instruments of transfer, in form satisfactory to the Company, duly
executed by the registered holder or its duly authorized attorney) and, in case
such surrender shall be made during the period from the close of business on the
Regular Record Date immediately preceding any Interest Payment Date through the
close of business on the last trading day immediately preceding such Interest
Payment Date (unless this Convertible Subordinated Note or the portion thereof
being converted has been called for redemption on a date in such period), also
accompanied by payment, in funds acceptable to the Company, of an amount equal
to the interest and Liquidated Damages, if any, otherwise payable on such
Interest Payment Date on the principal amount of this Convertible Subordinated
Note then being converted. Subject to the aforesaid requirement for a payment in
the event of conversion after the close of business on a Regular Record Date
immediately preceding an Interest Payment Date, no adjustment shall be made on
conversion for interest or Liquidated Damages accrued hereon or for dividends on
Common Stock delivered on conversion. The right to convert this Convertible
Subordinated Note is subject to the provisions of the Indenture relating to
conversion rights in the case of certain consolidations, mergers, or sales or
