     The Definitive Notes and the global notes representing the Book-Entry Notes (the “Global
Notes”) shall be typewritten, printed, lithographed or engraved or produced by any combination of
these methods (with or without steel engraved borders), all as determined by the officers executing
such Notes, as evidenced by their execution of such Notes.

     Each Note shall be dated the date of its authentication. The terms of the Notes set forth in
Exhibit A-1 and Exhibit A-2 are part of the terms of this Indenture.

     SECTION 2.2 Execution, Authentication and Delivery.

     The Notes shall be executed on behalf of the Issuer by any Authorized Officer of the Owner
Trustee. The signature of any such Authorized Officer on the Notes may be manual or facsimile.

     Notes bearing the manual or facsimile signature of individuals who were at any time Authorized
Officers of the Owner Trustee shall bind the Issuer, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and delivery of such Notes or
did not hold such offices at the date of such Notes.

     The Note Registrar shall, upon Issuer Order, authenticate and deliver the Notes for original
issue in the aggregate principal or notional amounts with respect to each Class as specified below:

     The aggregate principal amounts of such Classes of Notes that are Outstanding at any time may
not exceed such respective amounts.

     The Notes will be issued in minimum principal amount denominations of $100,000 and integral
multiples of $1 in excess thereof.

     No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for
any purpose, unless there appears on such Note a certificate of authentication substantially in the
form provided for herein executed by the Securities Administrator by the manual signature of one of
its authorized signatories, and such certificate upon any Note shall be conclusive evidence, and
the only evidence, that such Note has been duly authenticated and delivered hereunder.

     SECTION 2.3 Limitation on Transfer of Notes.

     (a) No Definitive Note shall be transferred unless the Note Registrar shall have received a
representation from the transferee of such Note, satisfactory to the Note Registrar (such
requirement is satisfied only by the Note Registrar’s receipt of a transfer affidavit from the
transferee substantially in the form of Exhibit B hereto), to the effect that:

     (i) such transferee is not acquiring such Note for, or with the assets of, (A) a
retirement plan or an employee benefit plan or arrangement subject to Title I of ERISA or
Section 4975 of the Code or a governmental plan (as defined in Section 3(32) of ERISA) or a
church plan (as defined in Section 3(33) of ERISA) or other employee benefit plan or
arrangement that is subject to any federal, state or local law (“Similar Law”) materially
similar to the foregoing provisions of ERISA or the Code (each, a “Plan”) or (B) any Person
who is directly or indirectly purchasing such Note or interest therein on behalf of, or with
“plan assets” (as defined under the Department of Labor Regulation (the “DOL Regulations”)
at 29 C.F.R. Section 25 10.3-101) or corresponding provisions of Similar Law) of a Plan; or

9

 

     (ii) the acquisition and
holding of the Note or any interest therein will not give rise to a nonexempt prohibited
transaction under ERISA or Section 4975 of the Code or similar violation of Similar Law.

     In the case of a Note that is a Book-Entry Note, for purposes of clauses (i) or (ii) of the
preceding paragraph, such representations shall be deemed to have been made to the Note Registrar
by the transferee’s acceptance of such Note that is also a Book-Entry Note (or the acceptance by a
Beneficial Noteholder of the beneficial interest in such Note).

     None of the Issuer, the Indenture Trustee, the Note Registrar, the Securities Administrator or
the Depositor shall have any liability to any Person for any registration of transfer of any Note
that is in fact not permitted by this Section 2.3(a) or for the Indenture Trustee or the Securities
Administrator (or any Paying Agent on their behalf) making any payments due on such Note to its
Noteholder thereof or taking any other action with respect to such Noteholder under the provisions
of this Indenture so long as the transfer was registered by the Note Registrar in accordance with
the foregoing requirements. In addition, none of the Issuer, the Indenture Trustee, the Note
Registrar, the Securities Administrator or the Depositor shall be required to monitor, determine or
inquire as to compliance with the transfer restrictions with respect to any Note in the form of a
Book-Entry Note, and none of the Issuer, the Indenture Trustee, the Note Registrar, the Securities
Administrator or the Depositor shall have any liability for transfers of Book-Entry Notes or any
interests therein made in violation of the restrictions on transfer described in the Prospectus and
this Indenture.

     In the event that a Note is transferred to a Person that does not meet the requirements of
this Section 2.3, such transfer shall be of no force and effect, shall be void ab initio and shall
not operate to transfer any rights to such Person, notwithstanding any instructions to the contrary
to the Issuer, the Indenture Trustee, the Note Registrar or any intermediary. The Securities
Administrator shall not make any payments on such Note for as long as such Person is the Noteholder
of such Note.

     The Issuer shall cause each Note to contain a legend substantially similar to the applicable
legend provided in Exhibit A-1 and Exhibit A-2 hereto stating that the transfer of
such Notes is subject to certain restrictions as set forth herein.

     (b) Any purported transfer of a Note (or any interest therein) not in accordance with this
Section 2.3 shall be void ab initio and shall not be given effect for any purpose hereunder.

     (c) Any Retained Notes will be subject to the same transfer restrictions applicable to the
Certificate as set forth in section 3.3 of the Owner Trust Agreement unless either (a) the Retained
Notes are sold to a party that is a taxable REIT subsidiary or is not affiliated with the owner of
the Certificate and at the time of such sale: (i) the owner of the Certificate is a Permitted
Transferee; (ii) no modifications have been made to the transaction documents; (iii) the respective
ratings of the Retained Notes as of the date of such sale is not lower than the rating of such
Retained Note as of the closing date; and (iv) no adverse changes have been made to (or that would
adversely affect the application of) the legal authorities applicable to the closing date tax
opinion or (b) the holder of the Retained Notes otherwise receives a “will be debt” tax

10

 

opinion from a law firm generally recognized to be qualified to opine concerning the tax
aspects of asset securitization. For purposes of this Section 2.3(c), in determining whether a
holder of Retained Notes complies with the provisions of Section 3.3 of the Owner Trust Agreement,
such holder will be deemed to be the Certificateholder.

     (d) None of the Issuer, the Note Registrar, the Securities Administrator or the Indenture
Trustee will have the ability, duty or obligation to monitor transfers of the Notes while they are
in book-entry form and will have no liability for transfers of Book-Entry Notes in violation of any
of the transfer restrictions described in this Section 2.3.

     (e) No transfer, sale, pledge or other disposition of any Class N Note or interest therein
shall be made unless that transfer, sale, pledge or other disposition is exempt from the
registration and/or qualification requirements of the Securities Act and any applicable state
securities laws, or is otherwise made in accordance with the Securities Act and such state
securities laws. If a transfer of any Class N Note is to be made without registration under the
Securities Act (other than in connection with the initial issuance thereof or a transfer thereof by
the Depositor or one of its Affiliates), then the Note Registrar shall refuse to register such
transfer unless it receives (and upon receipt, may conclusively rely upon) a certificate from the
Noteholder desiring to effect such transfer substantially in the form attached as Exhibit
C-1 hereto (which in the case of Book-Entry Notes, the Note Owner will be deemed to have
represented such certification) and a certificate from such Noteholder’s prospective transferee
substantially in the form attached as Exhibit C-2 hereto (which in the case of the
Book-Entry Notes, the Note Owner’s prospective transferee will be deemed to have represented such
certification). None of the Issuer, the Depositor, the Indenture Trustee or the Note Registrar is
obligated to register or qualify any Notes under the Securities Act or any other securities law or
to take any action not otherwise required under this Indenture to permit the transfer of any Note
or interest therein without registration or qualification. Any Noteholder desiring to effect a
transfer of Notes or interests therein shall, and does hereby agree to, indemnify the Issuer, the
Depositor, the Securities Administrator, the Owner Trustee, the Indenture Trustee and the Note
Registrar against any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

     (f) Notwithstanding the foregoing, neither an Opinion of Counsel nor a certification will be
required in connection with the initial transfer of any Class N Note by the Depositor to an
Affiliate of the Depositor or by an Affiliate to another Affiliate (in which case, the Depositor or
any Affiliate thereof shall be deemed to have represented that such Affiliate is not a Plan or any
Person investing “plan assets” of any Plan) and the Note Registrar shall be entitled to
conclusively rely upon a representation (which, upon the request of the Note Registrar, shall be a
written representation) from the Depositor of the status of such transferee as an Affiliate of the
Depositor.

     SECTION 2.4 Registration; Registration of Transfer and Exchange. 

     The Issuer shall cause the Note Registrar to keep a register (the “Note Register”) in which,
subject to such reasonable regulations as the Note Registrar may prescribe and the restrictions on
transfers of the Notes set forth herein, the Issuer shall provide for the registration of Notes and
the registration of transfers of Notes. The Securities Administrator shall be the

11

 

initial Note Registrar. Upon any resignation of any Note Registrar, the Issuer shall promptly
appoint a successor or, if it elects not to make such an appointment, assume the duties of Note
Registrar. If a Person other than the Indenture Trustee or the Securities Administrator is
appointed by the Issuer as Note Registrar, the Issuer will give the Indenture Trustee and the
Securities Administrator prompt written notice of the appointment of such Note Registrar and of the
location, and any change in the location, of the Note Register.

     The Indenture Trustee shall have the right to inspect the Note Register at all reasonable
times and to obtain copies thereof, and the Indenture Trustee shall have the right to rely upon a
certificate executed on behalf of the Note Registrar by an Executive Officer thereof as to the
names and addresses of the Noteholders and the principal amounts and number of such Notes.

     Subject to Section 2.3, upon surrender for registration of transfer of any Note at the office
of the Note Registrar to be maintained as provided in Section 3.2, the Issuer shall execute, and
the Note Registrar shall authenticate upon receipt of an Issuer Order and the Noteholder shall be
entitled to obtain from the Note Registrar, in the name of the designated transferee or
transferees, one or more new Notes of the same Class in any authorized denominations, of a like
aggregate principal amount.

     At the option of the Noteholder, Notes may be exchanged for other Notes of the same Class in
any authorized denominations, of a like aggregate principal amount, upon surrender of the Notes to
be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the
Issuer shall execute, and the Note Registrar shall authenticate upon receipt of an Issuer Order and
the Noteholder shall be entitled to obtain from the Note Registrar, the Notes which the Noteholder
making the exchange is entitled to receive.

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

     Every Note presented or surrendered for registration of transfer or exchange shall be (a) duly
endorsed by the Noteholder thereof, or accompanied by a written instrument of transfer satisfactory
to the Note Registrar and (b) duly executed by the Noteholder thereof or such Noteholder’s attorney
duly authorized in writing, with such signature guaranteed by an “eligible guarantor institution”
meeting the Note Registrar’s requirements, including membership or participation in the Securities
Transfer Agent’s Medallion Program (“STAMP”) or another “signature guarantee program” as may be
determined by the Note Registrar in addition to, or in substitution for, STAMP.

     No service charge shall be made to a Noteholder for any registration of transfer or exchange
of Notes, but the Issuer or the Note Registrar may require payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any registration of
transfer or exchange of Notes, other than exchanges pursuant to this Section 2.4 not involving any
transfer.

12

 

     The preceding provisions of this Section notwithstanding, the Note Registrar need not register
and shall not be required to transfer or exchange those Notes selected for redemption for a period
of 15 days preceding the due date for any payment with respect to such Note.

     SECTION 2.5 Mutilated, Destroyed, Lost or Stolen Notes.

     If (a) any mutilated Note is surrendered to the Note Registrar, or the Note Registrar receives
evidence to its satisfaction of the destruction, loss or theft of any Note, and (b) there is
delivered to the Note Registrar such security or indemnity as may be required by it to hold the
Issuer and the Note Registrar harmless, then, in the absence of actual notice to the Issuer, Note
Registrar or Indenture Trustee that such Note has been acquired by a protected purchaser, and upon
certification provided by the Noteholder of such Note that the requirements of Section 8-405 of the
UCC are met, the Issuer shall execute, and upon its request the Indenture Trustee shall
authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Note, a replacement Note; provided, however, that if any such destroyed, lost or stolen
Note, but not a mutilated Note, shall have become or within seven days shall be due and payable, or
shall have been called for redemption, instead of issuing a replacement Note, the Issuer may pay
such destroyed, lost or stolen Note when so due or payable or upon the Redemption Date without
surrender thereof. If, after the delivery of such replacement Note or payment of a destroyed, lost
or stolen Note pursuant to the proviso to the preceding sentence, a protected purchaser of the
original Note in lieu of which such replacement Note was issued presents for payment such original
Note, the Issuer, the Indenture Trustee and the Note Registrar shall be entitled to recover such
replacement Note (or such payment) from the Person to whom it was delivered or any Person taking
such replacement Note from such Person to whom such replacement Note was delivered or any assignee
of such Person, except a protected purchaser, and shall be entitled to recover upon the security or
indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the
Issuer, the Indenture Trustee or the Note Registrar in connection therewith.

     Upon the issuance of any replacement Note under this Section, the Issuer, the Indenture
Trustee or the Note Registrar may require the payment by the Noteholder of such Note of a sum
sufficient to cover any tax or other governmental charge that may be imposed in relation thereto
and any other reasonable expenses (including the fees and expenses of the Indenture Trustee or the
Note Registrar) connected therewith.

     Every replacement Note issued pursuant to this Section in replacement of any mutilated,
destroyed, lost or stolen Note shall constitute an original additional contractual obligation of
the Issuer, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Notes duly issued hereunder.

     The provisions of this Section are exclusive and shall preclude (to the extent lawful) all
other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost
or stolen Notes.

13

 

     SECTION 2.6 Persons Deemed Noteholders. 

     Prior to due presentment for registration of transfer of any Note, the Issuer, the Note
Registrar, the Indenture Trustee and any of their agents may treat the Person in whose name any
Note is registered (as of the day of determination) as the Noteholder of such Note for the purpose
of receiving payments of principal of and interest, if any, on such Note and for all other purposes
whatsoever, whether or not such Note be overdue, and none of the Issuer, the Note Registrar, the
Indenture Trustee or any of their agents shall be affected by notice to the contrary.

     SECTION 2.7 Payment of Principal and Interest.

     (a) On each Payment Date, the Indenture Trustee, or the Paying Agent on its behalf, will be
required to make payments of principal and interest on the Notes from amounts available therefor in
accordance with Section 7.7 of the Transfer and Servicing Agreement.

     (b) Any installment of interest or principal payable on any Note shall be paid on the
applicable Payment Date to the Person in whose name such Note (or one or more Predecessor Notes) is
registered on the related Record Date, by check, mailed first-class postage prepaid to such
Person’s address as it appears on the Note Register on such Record Date or, upon written request
made to the Paying Agent at least five Business Days prior to the related Record Date, by the
Noteholder having an initial Class Principal Amount of not less than $2,500,000, by wire transfer
in immediately available funds to an account specified in the request and at the expense of such
Noteholder, except that, unless Definitive Notes have been issued pursuant to Section 2.11, with
respect to Notes registered on such Record Date in the name of the nominee of the Depository
(initially, such nominee to be Cede & Co.), payment will be made by wire transfer in immediately
available funds to the account designated by such nominee, except for the final installment of
principal payable with respect to such Note on a Payment Date or on the applicable Maturity Date
for such class of Notes (and except for the Redemption Price for any Note called for redemption
pursuant to Section 10.1), which shall be payable as provided below. The funds represented by any
such checks returned undelivered shall be held in accordance with Section 3.3.

     (c) Each class of Notes shall accrue interest at the Note Interest Rate as set forth in the
Transfer and Servicing Agreement, and such interest shall be payable on each Payment Date, subject
to Section 3.1.

     (d) Interest shall be computed on each class of Offered Notes on the basis of a 360-day year
and the actual number of days elapsed in each Interest Accrual Period. Interest shall be computed
on the Class N Notes on the basis of a 360-day year consisting of twelve 30-day months, regardless
of the actual number of days elapsed. With respect to each class of Offered Notes then
Outstanding, the Securities Administrator shall determine LIBOR for each applicable Interest
Accrual Period on the second LIBOR Business Day prior thereto, in accordance with the provisions of
the Transfer and Servicing Agreement. All interest payments on each class of Notes shall be made
pro rata by Percentage Interest to the Noteholders of such Class entitled thereto.

14

 

     (e) The principal of the Notes shall be payable in installments on each Payment Date as
provided herein and in accordance with Section 7.7 of the Transfer and Servicing Agreement. The
entire unpaid principal amount of the Notes shall be due and payable, if not previously paid, on
the date on which an Indenture Event of Default shall have occurred and be continuing if the
Indenture Trustee or the Noteholders representing not less than a majority of the then-outstanding
Notes by aggregate Class Principal Amount have declared the Notes to be immediately due and payable
in the manner provided in Section 5.2. All principal payments on a class of Notes shall be made
pro rata by Percentage Interest to the Noteholders of such Class entitled thereto.

     (f) The Note Registrar shall notify the Person in whose name a Note is registered at the close
of business on the Record Date preceding the Payment Date on which the Issuer expects that the
final installment of principal of and interest on such Note will be paid. Such notice shall be
mailed or transmitted by facsimile no later than five Business Days prior to such final Payment
Date and shall specify that such final installment will be payable only upon presentation and
surrender of such Note and shall specify the place where such Note may be presented and surrendered
for payment of such installment. Notices in connection with redemptions of Notes shall be mailed
to Noteholders as provided in Section 10.2.

     SECTION 2.8 Cancellation.

     All Notes surrendered for payment, registration of transfer, exchange or redemption shall, if
surrendered to any Person other than the Indenture Trustee, be delivered to the Note Registrar and
shall be promptly cancelled by the Note Registrar. The Issuer may at any time deliver to the Note
Registrar for cancellation any Notes previously authenticated and delivered hereunder which the
Issuer may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly
cancelled by the Note Registrar. No Notes shall be authenticated in lieu of or in exchange for any
Notes cancelled as provided in this Section, except as expressly permitted by this Indenture. All
cancelled Notes may be held or disposed of by the Note Registrar in accordance with its standard
retention or disposal policy as in effect at the time unless the Issuer shall direct by an Issuer
Order that they be destroyed or returned to it; provided, that such Issuer Order is timely and the
Notes have not been previously disposed of by the Note Registrar.

     SECTION 2.9 Book-Entry Notes.

     (a) Each class of Notes will be issued in the form of typewritten Notes or Global Notes
representing the Book-Entry Notes, to be delivered to the initial Depository or to the Securities
Administrator as custodian for the initial Depository by, or on behalf of, the Issuer. The
Book-Entry Notes shall be registered initially on the Note Register in the name of Cede & Co., the
nominee of the initial Depository, and no Noteholder thereof will receive a Definitive Note
representing such Noteholder’s interest in such Note, except as provided in Section 2.11.

     (b) Unless and until definitive, fully registered Notes (the “Definitive Notes”) have been
issued to such Noteholders in exchange for the Global Notes representing the Book-Entry Notes
pursuant to Section 2.11:

     (i) the provisions of this Section shall be in full force and effect;

15

 

     (ii) the Note Registrar and the Indenture Trustee shall be entitled to deal with the
Depository for all purposes of this Indenture (including the payment of principal of and
interest on the Book-Entry Notes and the giving of instructions or directions hereunder) as
the sole holder of the Book-Entry Notes, and shall have no obligation to the Noteholders;

     (iii) to the extent that the provisions of this Section conflict with any other
provisions of this Indenture, the provisions of this Section shall control; and

     (iv) the rights of the Beneficial Noteholders shall be exercised only through the
Depository and shall be limited to those established by law and agreements between such
Beneficial Noteholders and the Depository and/or the Depository Participants.

     (c) Unless and until Definitive Notes are issued in exchange for the Global Notes representing
the Book-Entry Notes pursuant to Section 2.11:

     (i) the Note Registrar shall not register any transfer of a beneficial interest in a
Book-Entry Note;

     (ii) the initial Depository will make book-entry transfers among the Depository
Participants and receive and transmit payments of principal of and interest on the Notes to
such Depository Participants; and

     (iii) whenever this Indenture requires or permits actions to be taken based upon
instructions or directions of Noteholders evidencing a specified percentage of the
then-outstanding Notes by aggregate Class Principal Amount, the Depository shall be deemed
to represent such percentage only to the extent that it has received instructions to such
effect from the Beneficial Noteholders and/or Depository Participants owning or
representing, respectively, such required percentage of the beneficial interest in the Notes
and has delivered such instructions to the Indenture Trustee.

     SECTION 2.10 Notices to Depository.

     Whenever a notice or other communication to the Noteholders is required under this Indenture,
unless and until Definitive Notes shall have been issued to such Noteholders pursuant to Section
2.11, the Securities Administrator shall give all such notices and communications specified herein
to be given to the Beneficial Noteholders to the Depository, and shall have no obligation to such
Noteholders.

     SECTION 2.11 Definitive Notes.

     (a) Definitive Notes for Book-Entry Notes. If (i) the Depository is no longer willing
or able to properly discharge its responsibilities with respect to the Book-Entry Notes and the
Issuer is unable to locate a qualified successor or (ii) after the occurrence of an Indenture Event
of Default, the Beneficial Noteholders representing beneficial interests aggregating at least a
majority of the then-outstanding Book-Entry Notes by aggregate Class Principal Amount advise the
Depository in writing that the continuation of a book-entry system through the Depository is no
longer in the best interests of such Beneficial Noteholders, then the Depository shall notify all

16

 

Noteholders, the Beneficial Noteholders, the Note Registrar, the Securities Administrator and
the Indenture Trustee of the occurrence of any such event and of the availability of Definitive
Notes to the Beneficial Noteholders requesting the same. Upon surrender to the Securities
Administrator of the typewritten Notes representing the Book-Entry Notes by the Depository,
accompanied by registration instructions, the Issuer shall execute and upon receipt of an Issuer
Order the Note Registrar shall authenticate the Definitive Notes in accordance with the
instructions of the Depository. None of the Issuer, the Note Registrar or the Indenture Trustee
shall be liable for any delay in delivery of such instructions and may conclusively rely on, and
shall be protected in relying on, such instructions. Upon the issuance of Definitive Notes, the
Indenture Trustee and the Note Registrar shall recognize the former Beneficial Noteholders as
holders of the Definitive Notes and as Noteholders.

     SECTION 2.12 Tax Treatment.

     The Issuer has entered into this Indenture, and the Notes will be issued, with the intention
that, for federal, state and local income and franchise tax purposes, the Notes will qualify as
indebtedness of the Issuer secured by the Trust Fund. The Issuer, by entering into this Indenture,
and each Noteholder, by its acceptance of a Note (and each Noteholder by its acceptance of an
interest in the applicable Book-Entry Note), agree to treat the Notes for federal, state and local
income and franchise tax purposes as indebtedness of the Issuer.

ARTICLE III

COVENANTS

     SECTION 3.1 Payment of Principal and Interest.

     The Issuer will duly and punctually pay (or will cause to be duly and punctually paid) the
principal of and interest on the Notes in accordance with the terms of the Notes, the Transfer and
Servicing Agreement and this Indenture. Amounts properly withheld under the Code by any Person
from a payment to any Noteholder of interest and/or principal shall be considered as having been
paid by the Issuer to such Noteholder for all purposes of this Indenture. In order to receive
payments free from or at a reduced rate of withholding, each Noteholder, Beneficial Noteholder and
any transferees thereof agree and acknowledges that no legal or beneficial interest in all or any
portion of any Note may be obtained or transferred unless such person provides to the Note
Registrar a duly executed Internal Revenue Service (“IRS”) Form W-9, IRS Form W-8BEN, IRS Form
W-8IMY (together with all appropriate attachments), or IRS Form W-8ECI (or in each case the
appropriate successor form) claiming complete exemption from, or a reduced rate of, United States
federal withholding tax. Each such form must be signed under penalties of perjury and replaced
every three years (or earlier of there is a change in information) or as required by law.

     The Notes shall be non-recourse obligations of the Issuer and shall be limited in right of
payment to amounts available from the Trust Fund as provided in this Indenture. The Issuer shall
not otherwise be liable for payments of the Notes, and none of the owners, agents, officers,
directors, employees, or successors or assigns of the Issuer shall be personally liable for any
amounts payable, or performance due, under the Notes or this Indenture. If any other provision

17

 

of this Indenture shall be deemed to conflict with the provisions of this Section 3.1, the
provisions of this Section 3.1 shall control.

     SECTION 3.2 Maintenance of Office or Agency.

     The Note Registrar on behalf of the Issuer will maintain an office or agency where Notes may
be surrendered for registration of transfer or exchange, and where notices and demands to or upon
the Issuer in respect of the Notes and this Indenture may be served.

     SECTION 3.3 Money for Payments to be Held in Trust.

     (a) As provided in Section 2.7, all payments of amounts due and payable with respect to any
Notes that are to be made from amounts withdrawn from the Payment Account and paid pursuant to the
Transfer and Servicing Agreement shall be made on behalf of the Issuer by the Indenture Trustee or
by the Paying Agent, and no amounts so withdrawn from such account for payments with respect to the
Notes shall be paid over to the Issuer except as provided in this Section.

     (b) Any Paying Agent shall be appointed by Issuer Order with written notice thereof to the
Indenture Trustee; provided that the Securities Administrator is appointed hereby as the initial

Paying Agent (other than the Securities Administrator or the Indenture Trustee) which is not, at
the time of such appointment, an institution:

     (i) that has:

     (A) commercial paper, short-term debt obligations, or other short-term
deposits are rated at least “A-1” or long-term unsecured debt obligations
are rated at least “A-” by S&P (or assigned comparable ratings by the other
Rating Agencies), if the amounts on deposit are to be held in the account
for no more than 365 days; or

     (B) commercial paper, short-term debt obligations, demand deposits, or
other short-term deposits are rated at least “A-1” by S&P, if the amounts on
deposit are to be held in the account for no more than 30 days and are not
intended to be used as credit enhancement; or

     (ii) that is the corporate trust department of a federal depository institution or
state-chartered depository institution subject to regulations regarding fiduciary funds on

in either case, has corporate trust powers and is acting in its fiduciary capacity.

     (c) The Issuer shall cause each Paying Agent other than the Indenture Trustee and the initial
Paying Agent (who hereby makes the covenants set forth below) to execute and deliver to the
Indenture Trustee an instrument in which such Paying Agent shall agree with the Indenture Trustee
(and if the Indenture Trustee acts as Paying Agent, it hereby so agrees), subject to the provisions
of this Section, that such Paying Agent will:

18

 

     (i) hold all sums held by it for the payment of amounts due with respect to the Notes
in trust for the benefit of the Persons entitled thereto until such sums shall be paid to
such Persons or otherwise disposed of as herein provided and pay such sums to such Persons
as herein provided;

     (ii) give the Indenture Trustee notice of any default by the Issuer of which the Paying
Agent has actual knowledge in the making of any payment required to be made with respect to

of the Indenture Trustee, forthwith pay to the Indenture Trustee all sums so held in trust
by such Paying Agent;

all sums held by it in trust for the payment of Notes if at any time it ceases to meet the
standards required to be met by a Paying Agent at the time of its appointment; and

     (v) comply with all requirements of the Code with respect to the withholding from any
payments made by it on any Notes of any applicable withholding taxes imposed thereon and
with respect to any applicable reporting requirements in connection therewith; provided,
however, that with respect to reporting requirements applicable to original issue discount,
the accrual of market discount or the amortization of premium on the Notes, the Depositor
shall have first provided the calculations pertaining thereto and the amount of any
resulting withholding taxes to the Indenture Trustee and the Paying Agent.

     (d) The Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture or for any other purpose, by Issuer Order direct any Paying Agent to pay to the
Indenture Trustee all sums held in trust by such Paying Agent, such sums to be held by the
Indenture Trustee upon the same trusts as those upon which the sums were held by such Paying Agent;
and upon such payment by any Paying Agent to the Indenture Trustee, such Paying Agent shall be
released from all further liability with respect to such money.

     (e) Subject to applicable laws with respect to escheat of funds, any money held by the
Indenture Trustee or any Paying Agent in trust for the payment of any amount due with respect to
any Note and remaining unclaimed for two years after such amount has become due and payable shall
be discharged from such trust and be paid to the Issuer on Issuer Order; and the Noteholder thereof
shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof
(but only to the extent of the amounts so paid to the Issuer), and all liability of the Indenture
Trustee or such Paying Agent with respect to such trust money shall thereupon cease; provided,
however, that the Indenture Trustee or such Paying Agent, before being required to make any such
repayment, shall give notice to the remaining Noteholders to surrender their Notes for cancellation
and notice that such money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such notice, any unclaimed balance of such money then
remaining will be repaid to the Issuer. The Indenture Trustee or Paying Agent shall also adopt and
employ, at the expense and direction of the Issuer,

19

 

any other reasonable means of notification of such repayment (including, but not limited to,
mailing notice of such repayment to Noteholders whose Notes have been called but have not been
surrendered for redemption or whose right to or interest in moneys due and payable but not claimed
is determinable from the records of the Indenture Trustee or of any Paying Agent, at the last
address of record for each such Noteholder).

     SECTION 3.4 Existence.

     (a) The Issuer will keep in full effect its existence, rights and franchises as a statutory
trust under the laws of the State of Delaware (unless it becomes, or any successor Issuer hereunder
is or becomes, organized under the laws of any other state or of the United States of America, in
which case the Issuer will keep in full effect its existence, rights and franchises under the laws
of such other jurisdiction) and will obtain and preserve its qualification to do business in each
jurisdiction in which such qualification is or shall be necessary to protect the validity and
enforceability of this Indenture, the Notes, the Trust Fund and each other instrument or agreement
included in the Trust Fund.

     (b) Any successor to the Owner Trustee appointed pursuant to Section 9.2 of the Owner Trust
Agreement shall be the successor Owner Trustee under this Indenture without the execution or filing

     (c) Upon any consolidation or merger of or other succession to the Owner Trustee, the Person
succeeding to the Owner Trustee under the Owner Trust Agreement may exercise every right and power
of the Owner Trustee under this Indenture with the same effect as if such Person had been named as
the Owner Trustee herein.

     SECTION 3.5 Protection of Trust Fund.

     (a) The Issuer, from time to time, will execute, deliver and file all such supplements and

executed pursuant to this Section 3.5 and hereby authorizes either of them to file in any
filing office any financing statement, amendment to financing statement, or continuation statement
required to be executed pursuant to this Section 3.5.

     SECTION 3.6 Opinions as to Trust Fund.

     On the Closing Date, the Issuer shall furnish to the Securities Administrator and the
Indenture Trustee an Opinion of Counsel to the effect that either, in the opinion of such counsel,
such action has been taken with respect to the recording and filing of this Indenture, any
indentures supplemental hereto, and any other requisite documents, and with respect to the
execution and filing of any financing statements and continuation statements, as are necessary to
make effective the lien and security interest of this Indenture, or stating that, in the opinion of
such counsel, no such action is necessary to make such lien and security interest effective.

     SECTION 3.7 Performance of Obligations.

     (a) The Issuer will not take any action and will use commercially reasonable efforts not to
permit any action to be taken by others that would release any Person from any of such Person’s
material covenants or obligations under any instrument or agreement included in the Trust Fund or
that would result in the amendment, hypothecation, subordination, termination or discharge of, or
impair the validity or effectiveness of, any such instrument or agreement, except as expressly
provided in this Indenture, the Transfer and Servicing Agreement or any other Operative Agreement.

     (b) The Issuer may contract with other Persons to assist it in performing its duties under
this Indenture, and any performance of such duties by a Person identified to the Indenture Trustee

surrender, or agree to any amendment, modification, supplement, termination, waiver or
surrender of, the terms of the Trust Fund or the Operative Agreements (except to the extent

of, or accelerate or delay the timing of, payments that are required to be made for the
benefit of the Noteholders or (B) reduce the aforesaid percentage of the Notes that is
required to consent to any such amendment, without the consent of the Noteholders
representing the aforesaid percentage of the then-outstanding Notes by Class Principal

judgment or decree for payment of the money due has been obtained by the Indenture Trustee as
provided hereinafter in this Article V, the Noteholders representing a majority of the
then-outstanding Notes by aggregate Class Principal, by written notice to the Issuer and the
Indenture Trustee, may rescind and annul such declaration and its consequences if:

     (i) the Issuer has paid or deposited with the Securities Administrator a sum sufficient
to pay:

     (A) all payments of principal of and interest on all affected Notes and
all other amounts that would then be due hereunder or upon such Notes if the
Indenture Event of Default giving rise to such acceleration had not
occurred; and

     (B) all sums paid or advanced by the Indenture Trustee hereunder and
the reasonable compensation, expenses, disbursements and advances of the
Indenture Trustee and their agents and counsel; and

     (ii) all Indenture Events of Default, other than the nonpayment of the principal of the
Notes that has become due solely by such acceleration, have been cured or waived as provided
in Section 5.12.

     No such rescission shall affect any subsequent default or impair any right consequent thereto.

     SECTION 5.3 Collection of Indebtedness and Suits for Enforcement by Indenture
Trustee.

     (a) In case the Issuer shall fail forthwith to pay amounts upon such demand, the Indenture
Trustee, in its own name and as trustee of an express trust, may, in its discretion, or shall, at
the direction of the Noteholders representing not less than a majority of the then-outstanding
Notes by aggregate Class Principal Amount institute a Proceeding for the collection of the sums so
due and unpaid, and may prosecute such Proceeding to judgment or final decree, and may enforce the
same against the Issuer upon such Notes and collect in the manner provided by law out of the
property of the Issuer upon such Notes, wherever situated, the moneys adjudged or decreed to be
payable.

     (b) If an Indenture Event of Default occurs and is continuing, the Indenture Trustee may, in
its discretion, or shall, at the direction of the Noteholders representing not less than a majority
of the then-outstanding Notes by aggregate Class Principal Amount, as more particularly provided in
Section 5.4, proceed to protect and enforce its rights and the rights of the Noteholders, by such
appropriate Proceedings as the Indenture Trustee shall deem most effective to protect and enforce
any such rights, whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper
remedy or legal or equitable right vested in the Indenture Trustee by this Indenture or by law.

30

 

     (c) In case there shall be pending, relative to the Issuer or any other obligor upon the Notes
or any Person having or claiming an ownership interest in the Trust Fund, Proceedings under Title
11 of the United States Code or any other applicable federal or state bankruptcy, insolvency or
other similar law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, or
liquidator, sequestrator or similar official shall have been appointed for or taken possession of
the Issuer or its property or such other obligor or Person, or in case of any other comparable
Proceedings relative to the Issuer or other obligor upon the Notes, or to the creditors or property
of the Issuer or such other obligor, the Indenture Trustee, irrespective of whether the principal
of any Notes shall then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Indenture Trustee shall have made any demand pursuant to the provisions
of this Section, shall be entitled and empowered, by intervention in such Proceedings or otherwise:

     (i) to file and prove a claim or claims for the whole amount of principal and interest
owing and unpaid in respect of the Notes and to file such other papers or documents as may
be necessary or advisable in order to have the claims of the Indenture Trustee (including
any claim for reasonable compensation to the Indenture Trustee and each predecessor
Indenture Trustee, and their respective agents, attorneys and counsel, and for reimbursement
of all expenses and liabilities incurred, and all advances made, by the Indenture Trustee
and each predecessor Indenture Trustee, except as a result of negligence or bad faith), and
of the Noteholders allowed in such Proceedings;

     (ii) unless prohibited by applicable law and regulations, to vote on behalf of the
Noteholders in any election of a trustee, a standby trustee or Person performing similar
functions in any such Proceedings;

     (iii) to collect and receive any moneys or other property payable or deliverable on any
such claims and to distribute all amounts received with respect to the claims of the
Noteholders and of the Indenture Trustee on their behalf; and

     (iv) to file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Indenture Trustee or the Noteholders allowed in
any Proceedings relative to the Issuer, its creditors and its property;

and any trustee, receiver, liquidator, custodian or other similar official in any such Proceeding
is hereby authorized by each of such Noteholders to make payments to the Indenture Trustee. In the
event that the Indenture Trustee shall consent to the making of payments directly to such
Noteholders, any trustee, receiver, liquidator, custodian or other similar official in any such
Proceeding is authorized to pay to the Indenture Trustee such amounts as shall be sufficient to
cover reasonable compensation to the Indenture Trustee, each predecessor Indenture Trustee and
their respective agents, attorneys and counsel, and all other expenses and liabilities incurred by
it or its agents, and all advances made by the Indenture Trustee and each predecessor Indenture
Trustee except as a result of negligence or bad faith.

     (d) Nothing herein contained shall be deemed to authorize the Indenture Trustee to authorize
or consent to or vote for or accept or adopt on behalf of any Noteholder any plan of

31

 

reorganization, arrangement, adjustment or composition affecting the Notes or the rights of
any Noteholder thereof or to authorize the Indenture Trustee to vote in respect of the claim of any
Noteholder in any such proceeding except, as aforesaid, to vote for the election of a trustee in
bankruptcy or similar Person.

     (e) All rights of action and of asserting claims under this Indenture, or under any of the
Notes, may be enforced by the Indenture Trustee without the possession of any of the Notes or the
production thereof in any trial or other Proceedings relative thereto, and any such action or
Proceedings instituted by the Indenture Trustee, shall be brought in its own name as trustee of an
express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements
and compensation of the Indenture Trustee, each predecessor Indenture Trustee and their respective
agents and attorneys, shall be for the ratable benefit of the Noteholders.

     (f) In any Proceedings brought by the Indenture Trustee (and also any Proceedings involving
the interpretation of any provision of this Indenture to which the Indenture Trustee shall be a
party), the Indenture Trustee shall be held to represent all Noteholders, and it shall not be
necessary to make any Noteholder a party to any such Proceedings.

     SECTION 5.4 Remedies; Priorities.

     (a) If an Indenture Event of Default shall have occurred and be continuing, the Indenture
Trustee may, and at the direction of the Noteholders representing a majority of the
then-outstanding Notes by aggregate Class Principal Amount, do one or more of the following
(subject to Section 5.5):

     (i) institute Proceedings in its own name and as trustee of an express trust for the
collection of all amounts then payable on the Notes or under this Indenture with respect
thereto, whether by declaration or otherwise, enforce any judgment obtained and collect from
the Issuer and any other obligor upon such Notes moneys adjudged due;

     (ii) institute Proceedings from time to time for the complete or partial foreclosure of
this Indenture with respect to the Trust Fund;

     (iii) exercise any remedies of a secured party under the UCC and take any other
appropriate action to protect and enforce the rights and remedies of the Indenture Trustee
and the Noteholders; and

     (iv) sell the Trust Fund or any portion thereof or rights or interest therein, at one
or more public or private sales called and conducted in any manner permitted by law;

provided, however, that the Indenture Trustee may not sell or otherwise liquidate any Trust Fund
following an Indenture Event of Default, other than an Indenture Event of Default described in
Section 5.1(a) or 5.1(b), unless (A) the proceeds of such sale or liquidation distributable to the
Noteholders are sufficient to discharge in full all amounts then due and unpaid upon such Notes in
respect of the Class Principal Amount and interest (including any Deferred Interest and Basis Risk
Shortfall), (B) the proceeds of such sale or liquidation are sufficient to pay all amounts due and
payable by the Issuer pursuant to the Operative Agreements; or (C) the Indenture Trustee determines
that the Trust Fund will not continue to provide sufficient funds for the payment of

32

 

principal of and interest on the Notes as they would have become due if the Notes had not been
declared due and payable, and the Indenture Trustee obtains the consent of the Noteholders
evidencing 66-2/3% of the then-outstanding Notes by aggregate Class Principal Amount. In
determining such sufficiency or insufficiency with respect to clauses (A), (B) and (C), the
Indenture Trustee may, but need not, obtain and rely upon an opinion of an Independent investment
banking or accounting firm of national reputation as to the feasibility of such proposed action and
as to the sufficiency of the Trust Fund for such purpose.

     (b) If the Indenture Trustee collects any money or property pursuant to this Article V, such
money or property shall be distributed in accordance with Section 7.7(f) of the Transfer and
Servicing Agreement.

     SECTION 5.5 Optional Preservation of the Trust Fund.

     If the Notes have been declared to be due and payable under Section 5.2 following an Indenture
Event of Default and such declaration and its consequences have not been rescinded and annulled,
the Indenture Trustee may elect to maintain possession of the Trust Fund. It is the desire of the
parties hereto and the Noteholders that there be at all times sufficient funds for the payment of
principal of and interest on the Notes, and the Indenture Trustee shall take such desire into
account when determining whether or not to maintain possession of the Trust Fund. In determining
whether to maintain possession of the Trust Fund, the Indenture Trustee may, but need not, obtain
and rely upon an opinion (at the expense of the Issuer) of an Independent investment banking or
accounting firm of national reputation as to the feasibility of such proposed action and as to the
sufficiency of the Trust Fund for such purpose.

     SECTION 5.6 Limitation of Suits.

     (a) Other than as otherwise expressly provided herein in the case of an Indenture Event of
Default, no Noteholder shall have any right to institute any Proceeding, judicial or otherwise,
with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless:

     (i) such Noteholder has previously given written notice to the Indenture Trustee of a
continuing Indenture Event of Default;

     (ii) Noteholders evidencing at least 25% of the then-outstanding Notes by aggregate
Class Principal Amount have made written request to the Indenture Trustee to institute such
Proceeding in respect of such Indenture Event of Default in its own name as Indenture
Trustee hereunder;

     (iii) such Noteholder or Noteholders have offered to the Indenture Trustee reasonable
indemnity against the costs, expenses and liabilities to be incurred in complying with such
request;

     (iv) the Indenture Trustee for 60 days after its receipt of such notice, request and
offer of indemnity has failed to institute such Proceedings;

33

 

     (v) no direction inconsistent with such written request has been given to the Indenture
Trustee during such 60-day period by Noteholders evidencing a majority of the
then-outstanding Notes by aggregate Class Principal Amount.

     (b) It is understood and intended that no one or more Noteholders shall have any right in any
manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb
or prejudice the rights of any other Noteholders or to obtain or to seek to obtain priority or
preference over any other Noteholders or to enforce any right under this Indenture, except in the
manner herein provided.

     (c) In the event the Indenture Trustee shall receive conflicting or inconsistent requests and
indemnity from two or more groups of Noteholders, each representing less than a majority of the
then-outstanding Notes by aggregate Class Principal Amount, the Indenture Trustee in its sole
discretion may determine what action, if any, shall be taken, notwithstanding any other provisions
of this Indenture.

     SECTION 5.7 Unconditional Rights of Noteholders To Receive Principal and Interest.

     Notwithstanding any other provisions in this Indenture, any Noteholder shall have the right,
which is absolute and unconditional, to receive payment of the principal of and interest, if any,
on such Note on or after the respective due dates thereof expressed in such Note or in this
Indenture (or, in the case of redemption, on or after the Redemption Date) and to institute suit
for the enforcement of any such payment, and such right shall not be impaired without the consent
of such Noteholder.

     SECTION 5.8 Restoration of Rights and Remedies.

     If the Indenture Trustee or any Noteholder has instituted any Proceeding to enforce any right
or remedy under this Indenture and such Proceeding has been discontinued or abandoned for any
reason or has been determined adversely to the Indenture Trustee or to such Noteholder, then and in
every such case the Issuer, the Indenture Trustee and the Noteholders shall, subject to any
determination in such Proceeding, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Indenture Trustee and the Noteholders
shall continue as though no such Proceeding had been instituted.

     SECTION 5.9 Rights and Remedies Cumulative.

     No right or remedy herein conferred upon or reserved to the Indenture Trustee or to the
Noteholders is intended to be exclusive of any other right or remedy, and every right and remedy
shall, to the extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

     SECTION 5.10 Delay or Omission Not a Waiver.

     No delay or omission of the Indenture Trustee or any Noteholder to exercise any right or
remedy accruing upon any Indenture Default or Indenture Event of Default shall impair any such

34

 

right or remedy or constitute a waiver of any such Indenture Default or Indenture Event of Default
or an acquiescence therein. Every right and remedy given by this Article V or by law to the
Indenture Trustee or to the Noteholders may be exercised from time to time, and as often as may be
deemed expedient, by the Indenture Trustee or by the Noteholders, as the case may be.

     SECTION 5.11 Control by Noteholders.

     (a) Except as otherwise provided in Section 5.2, the Noteholders evidencing a majority of the
then-outstanding Notes by aggregate Class Principal Amount, shall have the right to direct the
time, method and place of conducting any Proceeding for any remedy available to the Indenture
Trustee with respect to the Notes or exercising any trust or power conferred on the Indenture
Trustee; provided, that:

     (i) such direction shall not be in conflict with any rule of law or with this
Indenture;

     (ii) in the case of the Noteholders exercising such right and subject to the express
terms of Section 5.4, any direction to the Indenture Trustee to sell or liquidate the Trust
Fund must be submitted by the Noteholders representing not less than 66-2/3% of the
then-outstanding Notes by aggregate Class Principal Amount; and

     (iii) the Indenture Trustee may take any other action deemed proper by the Indenture
Trustee that is not inconsistent with such direction.

     (b) Notwithstanding the rights of the Noteholders set forth in Section 5.11(a) subject to
Section 6.1(h) the Indenture Trustee need not take any action that it determines might involve it
in liability or might materially adversely affect the rights of any Noteholders not consenting to
such action.

     SECTION 5.12 Waiver of Past Defaults.

     Prior to the declaration of the acceleration of the maturity of the Notes as provided in
Section 5.2, the Noteholders evidencing at least a majority of the then-outstanding Notes by
aggregate Class Principal Amount may waive, in writing, any past Indenture Default or Indenture
Event of Default and its consequences except an Indenture Default (a) in payment of principal of or
interest on any of the Notes or (b) in respect of a covenant or provision hereof, which cannot be
modified or amended without the consent of each Noteholder. In the case of any such waiver, the
Issuer, the Indenture Trustee, and the Noteholders shall be restored to their former positions and
rights hereunder, respectively; but no such waiver shall extend to any subsequent or other
Indenture Default or impair any right consequent thereto.

     Upon any such waiver, such Indenture Default shall cease to exist and be deemed to have been
cured and not to have occurred, and any Indenture Event of Default arising therefrom shall be
deemed to have been cured and not to have occurred, for every purpose of this Indenture; but
no such waiver shall extend to any subsequent or other Indenture Default or Indenture Event of
Default or impair any right consequent thereto.

35

 

     SECTION 5.13 Undertaking for Costs.

     All parties to this Indenture agree, and each Noteholder by such Noteholder’s acceptance
thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit against the
Indenture Trustee for any action taken, suffered or omitted by it as Indenture Trustee, the filing
by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such
court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against
any party litigant in such suit, having due regard to the merits and good faith of the claims or
defenses made by such party litigant. The provisions of this Section shall not apply to (a) any
suit instituted by the Indenture Trustee, (b) any suit instituted by any Noteholder or group of
Noteholders, in each case holding in the aggregate more than 10% of the then-outstanding Notes by
aggregate Class Principal Amount or (c) any suit instituted by any Noteholder for the enforcement
of the payment of principal of or interest on any Note on or after the respective due dates
expressed in such Note and in this Indenture (or, in the case of redemption, on or after the
Redemption Date).

     SECTION 5.14 Waiver of Stay or Extension Laws.

     The Issuer covenants (to the extent that it may lawfully do so) that it will not at any time
insist upon, or plead or in any manner whatsoever claim or take the benefit or advantage of, any
stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the
covenants or the performance of this Indenture; and the Issuer (to the extent that it may lawfully
do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will
not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but
will suffer and permit the execution of every such power as though no such law had been enacted.

     SECTION 5.15 Action on Notes.

     The Indenture Trustee’s right to seek and recover judgment on the Notes or under this
Indenture shall not be affected by the seeking, obtaining or application of any other relief under
or with respect to this Indenture. Neither the lien of this Indenture nor any rights or remedies
of the Indenture Trustee or the Noteholders shall be impaired by the recovery of any judgment by
the Indenture Trustee against the Issuer or by the levy of any execution under such judgment upon
any portion of the Trust Fund or upon any of the assets of the Issuer. Any money or property
collected by the Indenture Trustee shall be applied in accordance with Section 7.7(f) of the
Transfer and Servicing Agreement.

36

 

     SECTION 5.16 Performance and Enforcement of Certain Obligations.

     (a) Promptly following a request from the Indenture Trustee to do so, the Issuer shall take
all such lawful action as the Indenture Trustee may request to compel or secure the performance and
observance by the Seller, the Credit Risk Manager, the Depositor, the Master Servicer, the
Servicer, the Securities Administrator, as applicable, of each of their obligations to the Issuer
under or in connection with the Transfer and Servicing Agreement, and to exercise any and all
rights, remedies, powers and privileges lawfully available to the Issuer under or in connection
with the Transfer and Servicing Agreement to the extent and in the manner directed by the Indenture
Trustee, including the transmission of notices of default on the part of the Seller, the Depositor,
the Credit Risk Manager, the Servicer, the Securities Administrator or the Master Servicer, as
applicable, under the Transfer and Servicing Agreement and the institution of legal or
administrative actions or proceedings to compel or secure performance by the Seller, the Credit
Risk Manager, the Depositor, the Servicer, the Securities Administrator or the Master Servicer of
each of their applicable obligations under Transfer and Servicing Agreement.

     (b) If an Indenture Event of Default has occurred and is continuing, the Indenture Trustee
may, and at the direction (which direction shall be in writing or by telephone (confirmed in
writing promptly thereafter)) of the Noteholders evidencing a majority of the then-outstanding
Notes by Class Principal Amount, shall exercise all rights, remedies, powers, privileges and claims
of the Issuer against the Seller, the Depositor, the Credit Risk Manager, the Master Servicer, the
Servicer or the Securities Administrator under or in connection with the Transfer and Servicing
Agreement, including the right or power to take any action to compel or secure performance or
observance by the Seller, the Depositor, the Master Servicer, the Credit Risk Manager, the Servicer
or the Securities Administrator, of each of their applicable obligations to the Issuer thereunder
and to give any consent, request, notice, direction, approval, extension or waiver under the
Transfer and Servicing Agreement, and any right of the Issuer to take such action shall be
suspended.

ARTICLE VI

THE INDENTURE TRUSTEE

     SECTION 6.1 Duties of Indenture Trustee.

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

     (b) Except during the continuance of an Indenture Event of Default:

     (i) the Indenture Trustee undertakes to perform only such duties as are specifically
set forth in this Indenture and shall not be liable except for the performance of such
duties and obligations as are specifically set forth in this Indenture; and no implied
covenants or obligations shall be read into this Indenture against the Indenture Trustee;
and

37

 

     (ii) in the absence of bad faith on its part, the Indenture Trustee may conclusively
rely upon certificates or opinions furnished to the Indenture Trustee as to the truth of the
statements and the correctness of the opinions expressed therein; however, the Indenture
Trustee shall examine the certificates and opinions to determine whether or not they conform
on their face to the requirements of this Indenture.

     (c) The Indenture Trustee may not be relieved from liability for its own negligent action, its
own negligent failure to act, its own willful misconduct or its own bad faith, except that:

     (i) this paragraph does not limit the effect of paragraph (a) of this Section;

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

     (iii) the Indenture Trustee shall not be liable with respect to any action it takes or
omits to take in good faith in accordance with this Indenture or upon a direction received
by it from the requisite Noteholders pursuant to Article V; and

     (iv) the Indenture Trustee shall not be required to take notice or be deemed to have
notice or knowledge of (A) any failure by the Issuer to comply with its obligations
hereunder or in the Operative Agreements or (B) any Indenture Default or Indenture Event of
Default, unless a Responsible Officer of the Indenture Trustee assigned to and working in
its corporate trust department obtains actual knowledge of such Indenture Default or
Indenture Event of Default or shall have received written notice thereof. In the absence of
such actual knowledge or notice, the Indenture Trustee may conclusively assume that there is
no Indenture Default or Indenture Event of Default.

     (d) Every provision of this Indenture that in any way relates to the Indenture Trustee is
subject to the provisions of this Section.

     (e) The Indenture Trustee shall not be liable for indebtedness evidenced by or arising under
any of the Operative Agreements, including principal of or interest on the Notes, or interest on
any money received by it except as the Indenture Trustee may agree in writing with the Issuer.

     (f) Money held in trust by the Indenture Trustee need not be segregated from other funds
except to the extent required by law or the terms of this Indenture or the Transfer and Servicing
Agreement.

     (g) No provision of this Indenture shall require the Indenture Trustee to expend, advance or
risk its own funds or otherwise incur financial liability in the performance of any of its duties
hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to
believe that repayment of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it; provided, however, that the Indenture Trustee shall not refuse or fail to
perform any of its duties hereunder solely as a result of nonpayment of its normal fees and
expenses.

38

 

     (h) Every provision of this Indenture or any Operative Agreement relating to the conduct or
affecting the liability of or affording protection to the Indenture Trustee shall be subject to the
provisions of this Section 6.1 and Section 6.2 and to the provisions of the TIA.

     (i) The Indenture Trustee shall execute and deliver the Transfer and Servicing Agreement and
perform its duties thereunder.

     (j) The Indenture Trustee shall not have any duty or obligation to manage, make any payment
with respect to, register, record, sell, dispose of, or otherwise deal with the Trust Fund, or to
otherwise take or refrain from taking any action under, or in connection with, any document
contemplated hereby to which the Indenture Trustee is a party, except as expressly provided (i) in
accordance with the powers granted to and the authority conferred upon the Indenture Trustee
pursuant to this Indenture or any other Operative Agreement and (ii) in accordance with any
document or instruction delivered to the Indenture Trustee pursuant to the terms of this Indenture.
No implied duties or obligations shall be read into this Indenture or any Operative Agreement
against the Indenture Trustee. The Indenture Trustee agrees that it will, at the cost and expense
of the Issuer, promptly take all action as may be necessary to discharge any liens on any part of
the Trust Fund that result from actions by, or claims against itself (in its individual capacity,
and not in the capacity of Indenture Trustee) that are not related to the administration of the
Trust Fund.

     SECTION 6.2 Rights of Indenture Trustee.

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

     (b) Before the Indenture Trustee acts or refrains from acting, it may require an Officer’s
Certificate or an Opinion of Counsel, which shall not be at the expense of the Indenture Trustee.
The Indenture Trustee shall not be liable for any action it takes or omits to take in good faith in
reliance on an Officer’s Certificate or Opinion of Counsel. The right of the Indenture Trustee to
perform any discretionary act enumerated in this Indenture or in any Operative Agreement shall not
be construed as a duty and the Indenture Trustee shall not be answerable for other than its
negligence or willful misconduct in the performance of such act.

     (c) The Indenture Trustee may execute any of the trusts or powers hereunder or perform any
duties hereunder either directly or by or through agents or attorneys or a custodian or nominee.

     (d) The Indenture Trustee shall not be liable for any action it takes or omits to take in good
faith which it believes to be authorized or within its rights or powers; provided, that the
Indenture Trustee’s conduct does not constitute willful misconduct, negligence or bad faith.

     (e) The Indenture Trustee may consult with counsel, and any Opinion of Counsel with respect to
legal matters relating to this Indenture, any Operative Agreement and the Notes shall be full and
complete authorization and protection from liability in respect to any action taken, omitted or
suffered by it hereunder in good faith and in accordance with any Opinion of Counsel of such
counsel.

39

 

     (f) In the event that the Indenture Trustee is also acting as Paying Agent, Note Registrar or
Master Servicer hereunder or under any Operative Agreement, the rights and protections afforded to
the Indenture Trustee pursuant to this Article VI shall be afforded to such Paying Agent, Note
Registrar and Master Servicer.

     (g) The permissive rights of the Indenture Trustee enumerated herein shall not be construed as
duties.

     SECTION 6.3 Individual Rights of Indenture Trustee.

     (a) The Indenture Trustee in its individual or any other capacity may become the Noteholder or
pledgee of Notes and may otherwise deal with the Issuer or its Affiliates with the same rights it
would have if it were not Indenture Trustee. Any Paying Agent, Note Registrar, co-registrar or
co-paying agent may do the same with like rights. However, the Indenture Trustee must comply with
Section 6.11.

     SECTION 6.4 Indenture Trustee’s Disclaimer.

     (a) The Indenture Trustee shall not be responsible for and makes no representation as to the
validity or adequacy of any of the Operative Agreements or the Notes or the sufficiency of the
Trust Fund. The Indenture Trustee shall not be accountable for the Issuer’s use of the proceeds
from the Notes, and it shall not be responsible for any statement of the Issuer or the Servicer in
this Indenture, any Operative Agreement or in any other document issued in connection with the sale
of the Notes or in the Notes other than the Indenture Trustee’s certificate of authentication.

     SECTION 6.5 Notice of Indenture Defaults.

     If an Indenture Default occurs and is continuing and if a Responsible Officer of the Indenture
Trustee has actual knowledge thereof, the Indenture Trustee shall give prompt written notice
thereof to each Noteholder.

     SECTION 6.6 Reserved.

     SECTION 6.7 Compensation and Indemnity.

     The Indenture Trustee shall be entitled, as compensation for its services, to the Indenture
Trustee Fee, as provided in the Transfer and Servicing Agreement. The Indenture Trustee’s
compensation shall not be limited by any law on compensation of a trustee of an express trust. The
Indenture Trustee and any co-trustee shall be reimbursed on behalf of the Issuer from funds in the
Payment Account, as provided in the Transfer and Servicing Agreement, for all reasonable ordinary
out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the
compensation for its services (as provided in the Transfer and Servicing Agreement). Reimbursable
expenses under this Section shall include the reasonable compensation and expenses, disbursements
and advances of the Indenture Trustee’s agents, counsel, accountants and experts. The Issuer shall
indemnify the Indenture Trustee, any co-trustee and their respective employees, directors and
agents, as provided in the Transfer and Servicing Agreement, against any and all claim, loss,
liability or expense (including attorneys’ fees)

40

 

incurred by it in connection with the administration of this trust and the performance of its
duties hereunder or under any Operative Agreement. The Indenture Trustee or co-trustee, as
applicable, shall notify the Issuer and the Securities Administrator promptly of any claim for
which it may seek indemnity. Failure by the Indenture Trustee or the co-trustee, as applicable, to
so notify the Issuer and the Securities Administrator shall not relieve the Issuer or the
Securities Administrator of its obligations hereunder. The Issuer shall defend any such claim, and
the Indenture Trustee and any co-trustee may have separate counsel and the fees and expenses of
such counsel shall be payable on behalf of the Issuer from funds in the Payment Account. The
Issuer shall not be required to reimburse any expense or indemnify against any loss, liability or
expense incurred by the Indenture Trustee or any co-trustee through the Indenture Trustee’s or
co-trustee’s, as the case may be, own willful misconduct, negligence or bad faith.

     The Issuer’s obligations to the Indenture Trustee and any co-trustee pursuant to this Section
shall survive the resignation or removal of the Indenture Trustee and the termination or discharge
of this Indenture. When the Indenture Trustee or any co-trustee incurs expenses after the
occurrence of an Indenture Default specified in Section 5.1(d) or 5.1(e) with respect to the
Issuer, the expenses are intended to constitute expenses of administration under Title 11 of the
United States Code or any other applicable federal or state bankruptcy, insolvency or similar law.

     SECTION 6.8 Replacement of Indenture Trustee.

     (a) No resignation or removal of the Indenture Trustee and no appointment of a successor
Indenture Trustee shall become effective until the acceptance of such appointment by the successor
Indenture Trustee pursuant to this Section. The Indenture Trustee may resign at any time by giving
90 days’ written notice thereof to the Depositor, the Issuer, each Noteholder and each Rating
Agency. The Depositor may remove the Indenture Trustee if:

     (i) the Indenture Trustee fails to comply with Section 6.11;

     (ii) the Indenture Trustee is adjudged bankrupt or insolvent;

     (iii) a receiver or other public officer takes charge of the Indenture Trustee or its
property; or

     (iv) the Indenture Trustee otherwise becomes incapable of acting.

     (b) If the Indenture Trustee resigns or is removed or if a vacancy exists in the office of the
Indenture Trustee for any reason (the Indenture Trustee in such event being referred to herein as
the retiring Indenture Trustee), the Issuer shall promptly appoint a successor Indenture Trustee
that satisfies the eligibility requirements of Section 6.11.

     (c) The resigning or removed Indenture Trustee agrees to cooperate with any successor
Indenture Trustee in effecting the termination of the resigning or removed Indenture Trustee’s
responsibilities and rights hereunder and shall promptly provide such successor Indenture Trustee
all documents and records reasonably requested by it to enable it to assume the Indenture Trustee’s
functions hereunder.

41

 

     (d) A successor Indenture Trustee shall deliver a written acceptance of its appointment to the
retiring Indenture Trustee and to the Issuer. Thereupon the resignation or removal of the retiring
Indenture Trustee shall become effective, and the successor Indenture Trustee shall have all the
rights, powers and duties of the Indenture Trustee under this Indenture. The successor Indenture
Trustee shall mail a notice of its succession to the Noteholders. The retiring Indenture Trustee
shall promptly transfer all property held by it as Indenture Trustee to the successor Indenture
Trustee.

     (e) If a successor Indenture Trustee does not take office within 30 days after the retiring
Indenture Trustee resigns or is removed, the retiring Indenture Trustee, the Issuer or the
Noteholders evidencing a majority of the then-outstanding Notes by aggregate Class Principal Amount
may petition any court of competent jurisdiction for the appointment of a successor Indenture
Trustee.

     (f) If the Indenture Trustee fails to comply with Section 6.11, any Noteholder may petition
any court of competent jurisdiction for the removal of the Indenture Trustee and the appointment of
a successor Indenture Trustee.

     SECTION 6.9 Successor Indenture Trustee by Merger.

     If the Indenture Trustee consolidates with, merges or converts into, or transfers all or
substantially all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any further act shall be
the successor Indenture Trustee; provided, that such corporation or banking association shall be
otherwise qualified and eligible under Section 6.11. The Indenture Trustee shall provide each
Rating Agency prior written notice of any such transaction.

     In case at the time such successor or successors by merger, conversion or consolidation to the
Indenture Trustee shall succeed to the trusts created by this Indenture any of the Notes shall have
been authenticated but not delivered, any such successor to the Indenture Trustee may adopt the
certificate of authentication of any predecessor trustee and deliver such Notes so authenticated;
and in case at that time any of the Notes shall not have been authenticated, any successor to the
Indenture Trustee may authenticate such Notes either in the name of any predecessor hereunder or in
the name of the successor to the Indenture Trustee.

42

 

     SECTION 6.10 Appointment of Co-Indenture Trustee or Separate Indenture Trustee.

     (a) Notwithstanding any other provisions of this Indenture, at any time, for the purpose of
meeting any legal requirement of any jurisdiction in which any part of the Trust Fund may at the
time be located, the Indenture Trustee shall have the power and may execute and deliver all
instruments to appoint one or more Persons to act as a co-trustee or co-trustees, or separate
trustee or separate trustees, of all or any part of the Trust, and to vest in such Person or
Persons, in such capacity and for the benefit of the Noteholders, such title to the Trust Fund, or
any part hereof, and, subject to the other provisions of this Section, such powers, duties,
obligations, rights and trusts as the Indenture Trustee may consider necessary or desirable. No
co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a
successor trustee under Section 6.11 and no notice to Noteholders of the appointment of any
co-trustee or separate trustee shall be required under Section 6.8 hereof.

     (b) Every separate trustee and co-trustee shall, to the extent permitted by law, be appointed
and act subject to the following provisions and conditions:

     (i) all rights, powers, duties and obligations conferred or imposed upon the Indenture
Trustee shall be conferred or imposed upon and exercised or performed by the Indenture
Trustee and such separate trustee or co-trustee jointly (it being understood that such
separate trustee or co-trustee is not authorized to act separately without the Indenture
Trustee joining in such act), except to the extent that under any law of any jurisdiction in
which any particular act or acts are to be performed the Indenture Trustee shall be
incompetent or unqualified to perform such act or acts, in which event such rights, powers,
duties and obligations (including the holding of title to the Trust Fund or any portion
thereof in any such jurisdiction) shall be exercised and performed singly by such separate
trustee or co-trustee, but solely at the direction of the Indenture Trustee;

     (ii) no trustee hereunder shall be personally liable by reason of any act or omission
of any other trustee hereunder; and

     (iii) the Indenture Trustee may at any time accept the resignation of or remove any
separate trustee or co-trustee.

     (c) Any notice, request or other writing given to the Indenture Trustee shall be deemed to
have been given to each of the then separate trustees and co-trustees, as effectively as if given
to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to
this Indenture and the conditions of this Article VI. Each separate trustee and co-trustee, upon
its acceptance of the trusts conferred, shall be vested with the estates or property specified in
its instrument of appointment, either jointly with the Indenture Trustee or separately, as may be
provided therein, subject to all the provisions of this Indenture, specifically including every
provision of this Indenture relating to the conduct of, affecting the liability of, or affording
protection to, the Indenture Trustee. Every such instrument shall be filed with the Indenture
Trustee.

     (d) Any separate trustee or co-trustee may at any time constitute the Indenture Trustee, its
agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to

43

 

do any lawful act under or in respect of this Indenture on its behalf and in its name. If any
separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of
its estates, properties, rights, remedies and trusts shall vest in and be exercised by the
Indenture Trustee, to the extent permitted by law, without the appointment of a new or successor
trustee.

     SECTION 6.11 Eligibility; Disqualification.

     The Indenture Trustee shall at all times:

     (a) satisfy the requirements of TIA Section 310(a);

     (b) have a combined capital and surplus of at least $100,000,000 as set forth in its most
recently published annual report of condition;

     (c) have a long-term debt rating equivalent to “A” or better by the Rating Agencies or be
otherwise acceptable to the Rating Agencies; and

     The Indenture Trustee shall comply with TIA Section 310(b), including the optional provision
permitted by the second sentence of TIA Section 310(b)(9); provided, however, that there shall be
excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which other
securities of the Issuer are outstanding if the requirements for such exclusion set forth in TIA
Section 310(b)(1) are met.

     SECTION 6.12 Representations and Warranties.

     The Indenture Trustee hereby represents and warrants to the other parties hereto as of the
Closing Date or such other date as is specified, that:

     (a) The Indenture Trustee has been duly organized and is validly existing as a national
banking association in good standing under the laws of the United States of America, with full
power and authority to own its assets and conduct its business as presently being conducted.

     (b) The Indenture Trustee has the full power and authority to execute and deliver this
Indenture and to perform its obligations hereunder, and the execution, delivery and performance of
this Indenture (including all instruments of transfer to be delivered pursuant to this Indenture)
by the Indenture Trustee and the consummation of the transactions contemplated hereby have been
duly and validly authorized.

     (c) This Indenture constitutes a legal, valid and binding obligation of the Indenture Trustee,
enforceable against the Indenture Trustee in accordance with its terms, except as enforceability
may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws now or hereafter in effect affecting the enforcement of creditors’ rights in general and
except as such enforceability may be limited by general principles of equity (whether considered in
a proceeding at law or in equity).

44

 

     (d) None of the execution and delivery of this Indenture, the transactions contemplated hereby
or the fulfillment of or compliance with the terms and conditions of this Indenture will conflict
with or result in a breach of any of the terms, certificate of formation or operating Indenture or
any legal restriction or any Indenture or instrument to which the Indenture Trustee is now a party
or by which it is bound, or constitute a default or result in the violation of any law, rule,
regulation, order, judgment or decree to which Indenture Trustee or its property is subject, or
impair the ability of the Trust to realize on the Mortgage Loans, or impair the value of the
Mortgage Loans.

     (e) No consent, approval, authorization or order of any court or governmental agency or body
is required for the execution, delivery and performance by the Indenture Trustee of or compliance
by the Indenture Trustee with this Indenture, or if required, such consent, approval, authorization
or order has been obtained prior to the related Closing Date.

     (f) There is no action, suit, proceeding or investigation pending or to its knowledge
threatened against the Indenture Trustee which, either individually or in the aggregate, may result
in any material adverse change in the business, operations, financial condition, properties or
assets of the Indenture Trustee, or in any material impairment of the right or ability of the
Indenture Trustee to carry on its business substantially as now conducted, or which would draw into
question the validity of this Indenture or the Mortgage Loans or of any action taken or to be
contemplated herein, or which would be likely to impair materially the ability of the Indenture
Trustee to perform under the terms of this Indenture.

     SECTION 6.13 Preferential Collection of Claims Against Issuer.

     The Indenture Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). An Indenture Trustee which has resigned or been removed
shall be subject to TIA Section 311(a) to the extent indicated.

the then-outstanding Notes by aggregate Class Principal Amount thereof (hereinafter referred to as

Applicants desire to communicate with other Noteholders with respect to their rights under this
Indenture or under the Notes, then the Note Registrar shall, within five Business Days after the
receipt of such application, afford such Applicants access, during normal business hours, to the

Issuer, the Note Registrar and the Indenture Trustee that none of the Issuer, the Note Registrar or

as to the names and addresses of the Noteholders under this Indenture, regardless of the source

regulations prescribed from time to time by the Commission.

     (b) Unless the Issuer otherwise determines, the fiscal year of the Issuer shall end on
December 31 of each year.

     (c) Delivery of such reports, information and documents to the Indenture Trustee is for

constitute constructive notice of any information contained therein or determinable from
information contained therein, including the Issuer’s compliance with any of its covenants
hereunder (as to which the Indenture Trustee is entitled to rely exclusively on Officers’
Certificates).

     SECTION 7.4 Reports by Indenture Trustee.

     If required by TIA Section 313(a), within 60 days after each March 1, beginning with March 1,

COLLECTIONS AND RELEASES

     SECTION 8.1 Collection of Money.

     Except as otherwise expressly provided herein, the Indenture Trustee may demand payment or
delivery of, and shall receive and collect, directly and without intervention or assistance of any
fiscal agent or other intermediary, all money and other property payable to or receivable by the
Indenture Trustee pursuant to this Indenture. The Indenture Trustee shall apply all such money
received by it as provided in this Indenture. Except as otherwise expressly provided in this
Indenture, if any default occurs in the making of any payment or performance under any agreement or
instrument that is part of the Trust Fund, the Indenture Trustee may take such action as may be
appropriate to enforce such payment or performance, including the institution and prosecution of
appropriate Proceedings. Any such action shall be without prejudice to any right to claim an
Indenture Default or Indenture Event of Default under this Indenture and any right to proceed
thereafter as provided in Article V.

     SECTION 8.2 Release of Trust Fund.

     (a) Except as otherwise provided in subsections (b) and (c) of this Section and the terms of

and (iv)(A) Independent Certificates in accordance with TIA Sections 314(c) and 314(d)(1) or (B) an

require any such Independent Certificates; provided, however, that no such Independent Certificates
or Opinion of Counsel shall be necessary in respect of property released from the lien of the
Indenture in accordance with the provisions hereof if such property consists solely of cash. All
such releases shall be subject to the payment of the Indenture Trustee Fee and expenses pursuant to
Section 6.7.

     (b) The Servicer (or if the Servicer does not, the Master Servicer), on behalf of the Issuer,
shall be entitled to obtain a release from the lien of this Indenture and the release of the
Mortgage Files from the Custodian for any Mortgage Loan and the Mortgaged Property at any time:

     (i) after a payment of the Repurchase Price of the Mortgage Loan;

47

 

     (ii) after a Qualified Substitute Mortgage Loan is substituted for such Mortgage Loan
and payment of the Substitution Adjustment Amount, if any;

     (iii) after liquidation of the Mortgage Loan in accordance with the Transfer and
Servicing Agreement and the deposit of all Liquidation Proceeds and Insurance Proceeds in
the Collection Account;

     (iv) upon the termination of a Mortgage Loan (due to, among other causes, a prepayment
in full of the Mortgage Loan and sale or other disposition of the related Mortgaged
Property); or

     (v) as contemplated by Section 9.2 of the Transfer and Servicing Agreement.

     (c) The Indenture Trustee shall, if requested by the Servicer, temporarily release to such
party the Mortgage File pursuant to the provisions of the Transfer and Servicing Agreement and the

the Issuer’s pledge to the Indenture Trustee under the Indenture.

     (d) The Indenture Trustee shall, at such time as there are no Notes that are Outstanding and

Registrar and the Master Servicer pursuant to this Indenture, the Note Insurance Agreements or any
other Operative Agreement have been paid, release any remaining portion of the Trust Fund that
secured the Notes from the lien of this Indenture and release to the Issuer or any other Person
entitled thereto any funds then on deposit in the Collateral Account. The Indenture Trustee shall
release property from the lien of this Indenture pursuant to this subsection 8.2 only upon receipt
of an Issuer Request accompanied by an Officer’s Certificate, an Opinion of Counsel and (if

meeting the applicable requirements of Section 11.1 hereof.

ARTICLE IX

SUPPLEMENTAL INDENTURES

     SECTION 9.1 Supplemental Indentures Without Consent of Noteholders.

     (a) Without the consent of any Noteholder but with prior notice to each Rating Agency, the
Issuer, the Securities Administrator, the Depositor and the Indenture Trustee, when authorized by
an Issuer Order, at any time and from time to time, may enter into one or more supplemental
indentures (which shall conform to the provisions of the Trust Indenture Act as in force at the
date of the execution thereof), in form satisfactory to the Indenture Trustee, for any of the
following purposes:

     (i) to correct or amplify the description of any property at any time subject to the
lien of this Indenture, or better to assure, convey and confirm unto the Indenture Trustee
any property subject or required to be subjected to the lien of this Indenture, or to
subject to the lien of this Indenture additional property;

48

 

     (ii) to evidence the succession, in compliance with the applicable provisions hereof,
of another person to the Issuer, and the assumption by any such successor of the covenants
of the Issuer herein and contained in the Notes;

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

     (iv) to convey, transfer, assign, mortgage or pledge any property to or with the
Indenture Trustee;

     (v) (A) to cure any ambiguity, (B) to correct or supplement any provision herein or in
any supplemental indenture that may be inconsistent with any other provisions herein or in
any supplemental indenture or to conform the provisions hereof to those of any Prospectus,
(C) to obtain or maintain a rating for a class of Notes from a nationally recognized
statistical rating organization, (D) to make any other provisions with respect to matters or
questions arising under this Indenture; provided, however, that no such supplemental
indenture entered into pursuant to clause (D) of this subclause (v) shall adversely affect
in any material respect the interests of any Noteholder not consenting thereto;

     (vi) to evidence and provide for the acceptance of the appointment hereunder by a
successor trustee with respect to the Notes and to add to or change any of the provisions of
this Indenture as shall be necessary to facilitate the administration of the trusts
hereunder by more than one trustee, pursuant to the requirements of Article VI; or

     (vii) to modify, eliminate or add to the provisions of this Indenture to such extent as
shall be necessary to effect the qualification of this Indenture under the TIA or under any
similar federal statute hereafter enacted and to add to this Indenture such other provisions
as may be expressly required by the TIA;

provided, however, that no such supplemental indenture shall be entered into unless the Indenture
Trustee shall have received an Opinion of Counsel acceptable to the holder of the Certificate
stating that as a result of such supplemental indenture (i) the Trust will not be subject to United
States federal income tax at an entity level and (ii) the Notes will not lose their status as debt
for United States federal income tax purposes.

     The Indenture Trustee and the Securities Administrator are hereby authorized to join in the
execution of any such supplemental indenture and to make any further appropriate agreements and
stipulations that may be therein contained.

     (b) A letter from each Rating Agency to the effect that any supplemental indenture entered
into pursuant to this Section 9.1 will not cause the then-current ratings on the Notes to be
qualified, reduced or withdrawn (without regard to the Note Insurance Policy) shall constitute
conclusive evidence that such amendment does not adversely affect in any material respect the
interests of the Noteholders.

49

 

     SECTION 9.2 Supplemental Indentures with Consent of Noteholders.

     The Issuer, the Securities Administrator and the Indenture Trustee, when authorized by an
Issuer Order, also may, with prior notice to each Rating Agency and with the consent of the
Noteholders representing not less than 66-2/3% of the then-outstanding Notes by aggregate Class
Principal Amount, by Act of such Noteholders delivered to the Issuer and the Indenture Trustee,
enter into an indenture or supplemental indentures for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or of modifying in
any manner the rights of the Noteholders under this Indenture; provided, however, that no such
supplemental indenture shall, without the consent of the Noteholder of each Note affected,
adversely affect the interests of such Noteholders by (i) reducing in any manner the amount of, or
delay the timing of, payments in respect of any Note, (ii) altering the obligations of the Servicer
or the Master Servicer to make an Advance or altering the servicing standards set forth in the
Transfer and Servicing Agreement, (iii) reducing the aforesaid percentages of Notes the Noteholders
of which are required to consent to any such supplemental indenture, without the consent of the
Noteholders of all Notes affected thereby or (iv) permitting the creation of any lien ranking prior
to or on a parity with the lien of this Indenture with respect to any part of the Trust Fund or,
except as otherwise permitted or contemplated herein, terminating the lien of this Indenture on any
property at any time subject hereto or depriving any Noteholder of the security provided by the
lien of this Indenture; provided, further, that no such supplemental indenture shall be entered
into unless the Indenture Trustee shall have received an Opinion of Counsel acceptable to the
holder of the Certificate stating that as a result of such supplemental indenture (i) the Trust
will not be subject to United States federal income tax at the entity level and (ii) the Notes will
not lose their status as debt for United States federal income tax purposes.

     The Indenture Trustee may rely on an Opinion of Counsel to determine whether or not any Notes
would be affected by any supplemental indenture and any such determination shall be conclusive upon
all Noteholders, whether theretofore or thereafter authenticated and delivered hereunder.

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

     Promptly after the execution by the Issuer and the Indenture Trustee of any supplemental
indenture pursuant to this Section, the Issuer shall mail to the Noteholders to which such
amendment or supplemental indenture relates, and each Rating Agency a notice setting forth in
general terms the substance of such supplemental indenture. Any failure of the Indenture Trustee
to mail such notice, or any defect therein, shall not, however, in any way impair or affect the
validity of any such supplemental indenture.

50

 

     SECTION 9.3 Execution of Supplemental Indentures.

     In executing, or permitting the additional trusts created by any supplemental indenture
permitted by this Article IX or the modification thereby of the trusts created by this Indenture,
the Indenture Trustee shall be entitled to receive and shall be fully protected in relying upon, an
Opinion of Counsel to the effect provided below, in addition to the documents required under
Section 11.1. Each of the Indenture Trustee and the Securities Administrator may, but shall not be
obligated to, enter into any such supplemental indenture that affects the Indenture Trustee’s or
the Securities Administrator’s own rights, duties, liabilities or immunities under this Indenture
or otherwise.

     In connection with any supplemental indenture pursuant to this Article IX, the Indenture
Trustee shall be entitled to receive an Opinion of Counsel to the effect that such supplemental
indenture is authorized or permitted by this Indenture and that all conditions precedent to the
execution of such supplemental indenture in accordance with the relevant provisions of this Article
IX have been met.

     Nothing in this Section shall be construed to require that any Person obtain the consent of
the Indenture Trustee or the Securities Administrator to any amendment or waiver of any provision
of any document where the making of such amendment or the giving of such waiver without obtaining
the consent of the Indenture Trustee is not prohibited by this Indenture or by the terms of the
document that is the subject of the proposed amendment or waiver.

     SECTION 9.4 Effect of Supplemental Indenture.

     Upon the execution of any supplemental indenture pursuant to the provisions hereof, this
Indenture shall be and shall be deemed to be modified and amended in accordance therewith with
respect to the Notes affected thereby, and the respective rights, limitations of rights,
obligations, duties, liabilities and immunities under this Indenture of the Indenture Trustee, the
Issuer and the Noteholders shall thereafter be determined, exercised and enforced hereunder subject
in all respects to such modifications and amendments, and all the terms and conditions of any such
supplemental indenture shall be and be deemed to be part of the terms and conditions of this
Indenture for any and all purposes.

     SECTION 9.5 Conformity with Trust Indenture Act.

     Every amendment of this Indenture and every supplemental indenture executed pursuant to this
Article IX shall conform to the requirements of the Trust Indenture Act as then in effect so long
as this Indenture shall then be qualified under the Trust Indenture Act.

     SECTION 9.6 Reference in Notes to Supplemental Indentures.

     Notes authenticated and delivered after the execution of any supplemental indenture pursuant
to this Article IX may, and if required by the Indenture Trustee or the Securities Administrator
shall, bear a notation in a form approved by the Indenture Trustee as to any matter provided for in
such supplemental indenture. If the Issuer, the Securities Administrator or the Indenture Trustee
shall so determine, new Notes so modified as to conform to any such

51

 

supplemental indenture may be prepared and executed by the Issuer and authenticated and
delivered by the Note Registrar in exchange for Outstanding Notes.

ARTICLE X

REDEMPTION OF NOTES

     SECTION 10.1 Redemption.

     The Notes are subject to redemption pursuant to Section 9.2 of the Transfer and Servicing

Servicer, as applicable, shall deposit the Redemption Price of the Notes to be redeemed no later
than the Business Day prior to the Redemption Date with the Securities Administrator in the Payment

     (c) Notice of redemption of the Notes shall be given by the Securities Administrator in the

for any period after the date to which accrued interest is calculated for purposes of calculating
the Redemption Price.

ARTICLE XI

MISCELLANEOUS

     SECTION 11.1 Compliance Certificates and Opinions, etc.

     (a) Upon any application or request by the Issuer to the Indenture Trustee or the Securities
Administrator, Note Registrar or Paying Agent to take any action under any provision of this
Indenture, the Issuer shall furnish to the Indenture Trustee, Securities Administrator, the Note
Registrar or the Paying Agent, as applicable: (i) an Officer’s Certificate stating that all
conditions precedent, if any, provided for in this Indenture relating to the proposed action have
been complied with, (ii) an Opinion of Counsel stating that in the opinion of such counsel all such
conditions precedent, if any, have been complied with, and (iii) if required by the TIA, an
Independent Certificate from a firm of Independent Accountants meeting the applicable requirements
of this Section, except that, in the case of any such application or request as to which the
furnishing of such documents is specifically required by any provision of this Indenture, no
additional certificate or opinion need be furnished.

     (b) Every certificate or opinion with respect to compliance with a condition or covenant
provided for in this Indenture shall include:

     (i) a statement that each signatory of such certificate or opinion has read or has
caused to be read such covenant or condition and the definitions herein relating thereto;

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

     (iii) a statement that, in the opinion of each such signatory, such signatory has made
such examination or investigation as is necessary to enable such signatory to express an
informed opinion as to whether or not such covenant or condition has been complied with; and

     (iv) a statement as to whether, in the opinion of each such signatory, such condition
or covenant has been complied with.

     SECTION 11.2 Form of Documents Delivered.

     In any case where several matters are required to be certified by or covered by an opinion of
any specified Person, it is not necessary that all such matters be certified by or covered by the
opinion of only one such Person, or that they be so certified or covered by only one document, but
one such Person may certify or give an opinion with respect to some matters and one or more

53

 

other such Persons as to other matters, and any such Person may certify or give an opinion as
to such matters in one or several documents.

     Any certificate or opinion of an Authorized Officer of the Issuer may be based, insofar as it
relates to legal matters, upon a certificate or opinion of or representations by counsel, unless
such officer knows, or in the exercise of reasonable care should know, that the certificate or
opinion or representations with respect to the matters upon which such officer’s certificate or
opinion is based are erroneous. Any such certificate of an Authorized Officer or Opinion of
Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of or
representations by an officer or officers of the Depositor, the Issuer, the Servicer or the Master
Servicer, stating that the information with respect to such factual matters is in the possession of
the Depositor, the Issuer, the Servicer or the Master Servicer, unless such counsel knows, or in
the exercise of reasonable care should know, that the certificate or opinion or representations
with respect to such matters are erroneous.

     Where any Person is required to make, give or execute two or more applications, requests,
consents, certificates, statements, opinions or other instruments under this Indenture, they may,
but need not, be consolidated into one instrument.

     In connection with any application or certificate or report, if the Issuer is required to
deliver any document as a condition of the granting of such application or as evidence of the
Issuer’s compliance with any term hereof, it is intended that the truth and accuracy, at the time
of the granting of such application or at the effective date of such certificate or report (as the
case may be), of the facts and opinions stated in such document shall in such case be conditions
precedent to the right of the Issuer to have such application granted or to the sufficiency of such
certificate or report. The foregoing shall not, however, be construed to affect the right of the
Indenture Trustee, the Securities Administrator, the Paying Agent or the Note Registrar to rely
upon the truth and accuracy of any statement or opinion contained in any such document as provided
in Article VI.

     SECTION 11.3 Acts of Noteholders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Noteholders may be embodied in and evidenced by
one or more instruments of substantially similar tenor signed by such Noteholders in person or by
agents duly appointed in writing. Except as otherwise expressly provided herein, such action shall
become effective when such instrument or instruments are delivered to the Indenture Trustee and, if
expressly required, to the Issuer. Such instrument or instruments (and the action embodied therein
and evidenced thereby) are herein sometimes referred to as the “Act” of the Noteholders signing
such instrument or instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to
Section 6.1) conclusive in favor of the Indenture Trustee and the Issuer, if made in the manner
provided in this Section.

     (b) The fact and date of the execution by any person of any such instrument or writing may be
proved in any manner that the Indenture Trustee deems sufficient.

54

 

     (c) Ownership of Notes shall be proved by the Note Register.

     (d) Any request, demand, authorization, direction, notice, consent, waiver or other action by
any Noteholder shall bind the Noteholder of every Note issued upon the registration thereof or in
exchange therefor or in lieu thereof, in respect of anything done, omitted or suffered to be done
by the Indenture Trustee or the Issuer in reliance thereon, whether or not notation of such action
is made upon such Note.

	 	 	SECTION 11.4 Notices, etc., to the Indenture Trustee, the Securities Administrator, the
Issuer and the Rating Agencies.

     (a) Any request, demand, authorization, direction, notice, consent, waiver or Act of any
Noteholders or other documents provided or permitted by this Indenture shall be in writing. If
such request, demand, authorization, direction, notice, consent, waiver or Act of any Noteholders
is to be made upon, given or furnished to or filed with:

     (i) the Indenture Trustee by any Noteholder or by the Issuer, it shall be sufficient
for every purpose hereunder if made, given, furnished or filed in writing to or with the
Indenture Trustee at its Corporate Trust Office; or

     (ii) the Securities Administrator or the Note Registrar by the Indenture Trustee, by
any Noteholder or by the Issuer, it shall be sufficient for every purpose hereunder if made,
given, furnished or filed in writing to or with the Securities Administrator or the Note
Registrar at its Corporate Trust Office as applicable; or

     (iii) the Issuer by the Indenture Trustee, by the Securities Administrator or by any
Noteholder, it shall be sufficient for every purpose hereunder if in writing and mailed
first-class, postage prepaid to the Issuer addressed to the address provided in the Transfer
and Servicing Agreement, or at any other address previously furnished in writing to the
Indenture Trustee by the Issuer. The Issuer shall promptly transmit any notice received by
it from the Noteholders to the Indenture Trustee.

     (b) Notices required to be given to the Rating Agencies by the Issuer, the Indenture Trustee,
the Securities Administrator or the Owner Trustee shall be in writing, personally delivered or
mailed by certified mail, return receipt requested, to the address provided in the Transfer and
Servicing Agreement or such other address as shall be designated by written notice to the other
parties.

     SECTION 11.5 Notices to Noteholders; Waiver.

     Where this Indenture provides for notice to Noteholders of any event, such notice shall be in
writing and mailed, first-class, postage prepaid to each Noteholder affected by such event, at such
Noteholder’s address as it appears on the Note Register, not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice. In any case where notice
to Noteholders is given by mail, neither the failure to mail such notice nor any defect in any
notice so mailed to any particular Noteholder shall affect the sufficiency of such notice with
respect to other Noteholders, and any notice that is mailed in the manner herein provided shall
conclusively be presumed to have been duly given.

55

 

     Where this Indenture provides for notice in any manner, such notice may be waived in writing
by any Person entitled to receive such notice, either before or after the event, and such waiver
shall be the equivalent of such notice. Waivers of notice by Noteholders shall be filed with the
Indenture Trustee but such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such a waiver.

     If it shall be impractical to mail notice of any event of Noteholders due to suspension of
regular mail service as a result of a strike, work stoppage or similar activity, any manner of
giving such notice that is satisfactory to the Indenture Trustee shall be deemed to be sufficient.

     Where this Indenture provides for notice to the Rating Agencies, failure to give such notice
shall not affect any other rights or obligations created hereunder and shall not under any
circumstance constitute an Indenture Default or Indenture Event of Default.

     SECTION 11.6 Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with another provision hereof that is
required to be included in this Indenture by any of the provisions of the Trust Indenture Act, such
required provision shall control.

     The provisions of TIA Sections 310 through 317 that impose duties on any person (including the
provisions automatically deemed included herein unless expressly excluded by this Indenture) are a
part of and govern this Indenture, whether or not physically contained herein.

     SECTION 11.7 Effect of Headings and Table of Contents.

     The Article and Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

     SECTION 11.8 Successors and Assigns.

     All covenants and agreements in this Indenture and the Notes by the Issuer shall bind its
successors and assigns, whether so expressed or not. All agreements of the Indenture Trustee in
this Indenture shall bind its successors, co-trustees and agents.

     SECTION 11.9 Severability.

     In case any provision in this Indenture or in the Notes shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

     SECTION 11.10 Benefits of Indenture and Consents of Noteholders.

     Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other
than the parties hereto and their successors hereunder, the Owner Trustee and the Noteholders, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

56

 

Each Noteholder, by acceptance of a Note or a beneficial interest in a Note, consents to and
agrees to be bound by the terms and conditions of this Indenture.

     SECTION 11.11 Legal Holidays.

     If the date on which any payment is due is not a Business Day, notwithstanding any other
provision of the Notes or this Indenture, payment need not be made on such date but may be made on
the next succeeding Business Day with the same force and effect as if made on the date on which
nominally due, and no interest shall accrue for the period from and after any such nominal date.

     SECTION 11.12 Governing Law.

     This indenture shall be governed by and construed in accordance with the laws of the State of
New York, without reference to its conflict of law provisions (other than Section 5-1401 of the
general obligations law), and the obligations, rights and remedies of the parties hereunder shall
be determined in accordance with such laws.

     SECTION 11.13 Counterparts.

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

     SECTION 11.14 Recording of Indenture.

     If this Indenture is subject to recording in any appropriate public recording offices, such
recording is to be effected by the Issuer and at its expense accompanied by an Opinion of Counsel
(which may be counsel to the Indenture Trustee or any other counsel reasonably acceptable to the
Indenture Trustee) to the effect that such recording is necessary either for the protection of the
Noteholders or any other Person secured hereunder or for the enforcement of any right or remedy
granted to the Indenture Trustee under this Indenture.

     SECTION 11.15 Trust Obligations.

     (a) No recourse may be taken, directly or indirectly, with respect to the obligations of the
Issuer, the Owner Trustee, the Master Servicer, the Note Registrar, the Paying Agent, the
Securities Administrator or the Indenture Trustee on the Notes or under this Indenture or any
certificate or other writing delivered in connection herewith or therewith, against (i) the
Indenture Trustee, the Note Registrar, the Paying Agent, the Securities Administrator or the Owner
Trustee in their respective individual capacities, (ii) any owner of a beneficial interest in the
Issuer or (iii) any partner, owner, beneficiary, agent, officer, director, employee or agent of the

Paying Agent, or the Owner Trustee in its respective individual capacity, any holder of a
beneficial interest in the Issuer, the Owner Trustee, the Note Registrar, the Paying Agent, the
Securities Administrator or the Indenture Trustee or of any successor or assign of the Indenture
Trustee, the Securities Administrator, the Note Registrar, the Paying Agent or the Owner Trustee in
its individual capacity, except as any such Person may have expressly agreed (it being

57

 

understood that the Indenture Trustee, the Note Registrar, the Paying Agent, the Securities
Administrator and the Owner Trustee have no such obligations in their respective individual
capacities) and except that any such partner, owner or beneficiary shall be fully liable, to the
extent provided by applicable law, for any unpaid consideration for stock, unpaid capital
contribution or failure to pay any installment or call owing to such entity. For all purposes of
this Indenture, in the performance of any duties or obligations of the Issuer hereunder, the Owner
Trustee shall be subject to, and entitled to the benefits of, the terms and provisions of Articles
V, VI and VII of the Owner Trust Agreement.

     (b) In addition, (i) this Indenture is executed and delivered by Wilmington Trust Company, not
individually or personally but solely as Owner Trustee, in the exercise of the powers and authority
conferred and vested in it, (ii) each of the representations, undertakings and agreements herein
made on the part of the Issuer or the Owner Trustee is made and intended not as personal
representations, undertakings and agreements by Wilmington Trust Company but is made and intended
for the purpose for binding only the Trust, (iii) nothing herein contained shall be construed as
creating any liability on Wilmington Trust Company, individually or personally, to perform any
covenant either expressed or implied contained herein, all such liability, if any, being expressly
waived by the Indenture Trustee and by any Person claiming by, through or under the Indenture
Trustee, and (iv) under no circumstances shall Wilmington Trust Company be personally liable for
the payment of any indebtedness or expenses of the Issuer or be liable for the breach or failure of
any obligation, representation, warranty or covenant made or undertaken by the Issuer under this

     SECTION 11.16 No Petition.

     The Indenture Trustee and the Securities Administrator, by entering into this Indenture, and
each Noteholder, by accepting a Note, hereby covenant and agree that they will not at any time
institute against the Depositor or the Issuer, or join in any institution against the Depositor or
the Issuer of, any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings,

connection with any obligations relating to the Notes, this Indenture or any of the Operative
Agreements.

     SECTION 11.17 Inspection.

     The Issuer agrees that, on reasonable prior notice, it will permit any representative of the

and extracts therefrom, to cause such books to be audited by Independent Accountants, and to
discuss the Issuer’s affairs, finances and accounts with the Issuer’s officers, employees and
Independent certified public accountants, all at such reasonable times and as often as may be
reasonably requested. The Indenture Trustee or the Securities Administrator shall, and shall cause
its representatives to, hold in confidence all such information except to the extent disclosure may
be required by law (and all reasonable applications for confidential treatment are unavailing) and
except to the extent that the Indenture Trustee or the Securities Administrator may reasonably
determine that such disclosure is consistent with its obligations hereunder.

58

 

     IN WITNESS WHEREOF, the Issuer, the Securities Administrator and the Indenture Trustee have

registration of transfer at the office or agency designated by the Issuer pursuant to the
Indenture, duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Note Registrar duly executed by, the Noteholder hereof or such Noteholder’s
attorney duly authorized in writing, with such signature guaranteed by an “eligible guarantor
institution” meeting the requirements of the Note Registrar, which requirements include membership
or participation in the Securities Transfer Agent’s Medallion Program (“STAMP”) or such other
“signature guarantee program” as may be determined by the Note Registrar in addition to, or in
substitution for, STAMP, all in accordance with the Securities Exchange Act of 1934, as amended,
and thereupon one or more new Notes of authorized denominations and in the same aggregate principal
amount will be issued to the designated transferee or transferees. No service charge will be

or under the Indenture or any certificate or other writing delivered in connection therewith,
against (i) the Indenture Trustee, the Securities Administrator or the Owner Trustee in their

A-1-6

 

respective individual capacities, (ii) any owner of a beneficial interest in the Issuer or
(iii) any partner, owner, beneficiary, agent, officer, director or employee of the Indenture
Trustee, the Securities Administrator or the Owner Trustee in its individual capacity, any
Noteholder of a beneficial interest in the Issuer, the Owner Trustee, the Securities Administrator
or the Indenture Trustee or of any successor or assign of the Indenture Trustee, the Owner Trustee
or the Securities Administrator in its individual capacity, except as any such Person may have
expressly agreed and except that any such partner, owner or beneficiary shall be fully liable, to
the extent provided by applicable law, for any unpaid consideration for stock, unpaid capital
contribution or failure to pay any installment or call owing to such entity.

     Each Noteholder, by acceptance of a Note or a beneficial interest in a Note, covenants and
agrees by accepting the benefits of the Indenture that such Noteholder will not at any time

     Each Noteholder, by acceptance of a Note or a beneficial interest in a Note, consents to and
agrees to be bound by the terms and conditions of the Indenture and the Transfer and Servicing
Agreement.

     The Issuer has entered into the Indenture and this Note is issued with the intention that, for

interest in a Note, agrees to treat the Notes for all federal, state and local income tax purposes
as indebtedness (except that any Note held by a person that, for federal income tax purposes, owns

outstanding indebtedness).

Indenture Trustee, the Note Registrar, the Paying Agent and any agent of the Issuer or the
Indenture Trustee may treat the Person in whose name this Note (as of the day of determination or

all purposes, whether or not this Note be overdue, and none of the Issuer, the Indenture Trustee,
the Note Registrar, the Paying Agent or any such agent shall be affected by notice to the contrary.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof by
supplemental indenture and the modification of the rights and obligations of the Issuer and the
rights of the Noteholders of the Notes under the Indenture at any time by the Depositor, the Issuer
and the Indenture Trustee with the consent of the Noteholders representing not less than 66-2/3% of
the then-outstanding Notes by aggregate Class Principal Amount for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of
modifying in any manner the rights of the Noteholders. Any such consent or waiver by the
Noteholder of this Note shall be conclusive and binding upon such Noteholder and upon all future
Noteholders of this Note and of any Note issued upon the registration of transfer hereof or in
exchange hereof or in lieu hereof whether or not notation of

A-1-7

 

such consent or waiver is made upon this Note. The Indenture also permits the amendment
thereof, in certain limited circumstances, or the waiver of certain terms and conditions set forth
in the Indenture, without the consent of Noteholders of the Notes issued thereunder.

     The term “Issuer” as used in this Note includes any successor to the Issuer under the
Indenture.

     The Notes are issuable only in registered form in denominations as provided in the Indenture,
subject to certain limitations therein set forth.

     THIS NOTE AND THE INDENTURE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS (OTHER THAN SECTION
5-1401 OF THE GENERAL OBLIGATIONS LAW), AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES
HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

     No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the

interest on this Note or performance of, or omission to perform, any of the covenants, obligations
or indemnifications contained in the Indenture. The Noteholder of this Note by its acceptance
hereof agrees that, except as expressly provided in the Operative Agreements, in the case of an
Event of Default under the Indenture, the Noteholder shall have no claim against any of the
foregoing for any deficiency, loss or claim therefrom; provided, however, that nothing contained

     This Note is one of a duly authorized issue of Notes of the Issuer, all issued under the
Indenture, to which Indenture and all indentures supplemental thereto reference is hereby made for
a statement of the respective rights and obligations thereunder of the Issuer, the Indenture
Trustee and the Noteholders of the Notes. To the extent that any provision of this Note
contradicts or is inconsistent with the provisions of the Indenture, the provisions of the
Indenture shall control and supersede such contradictory or inconsistent provision herein. This
Note is subject to all terms of the Indenture and the Transfer and Servicing Agreement.

     Payments to each Noteholder shall be made (i) by check mailed to the Person whose name appears
as the Registered Noteholder of this Note on the books of the Note Registrar and Paying Agent as of
the close of business on each Record Date or (ii) upon written request made to the Note Registrar
and Paying Agent prior to the related Record Date by the Noteholder of a Note having an initial
Class Principal Amount of not less than $2,500,000, by wire transfer in immediately available funds
to an account specified in writing by such Noteholder. The final payment in retirement of this
Note shall be made only upon surrender of this Note to the Note Registrar and Paying Agent at the
office thereof specified in the notice to Noteholders of such final payment mailed prior to the
Payment Date on which the final payment is expected to be made to the Noteholder thereof.

     As provided in the Indenture and subject to certain limitations set forth therein, the
transfer of this Note may be registered by the Note Registrar upon surrender of this Note for

attorney duly authorized in writing, with such signature guaranteed by an “eligible guarantor
institution” meeting the requirements of the Note Registrar, which requirements include membership

charged for any registration of transfer or exchange of this Note, but the transferor may be
required to pay a sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any such registration of transfer or exchange.

     No transfer, sale, pledge or other disposition of this Note or interest herein shall be made
unless that transfer, sale, pledge or other disposition is exempt from the registration and/or
qualification requirements of the Securities Act and any applicable state securities laws, or is
otherwise made in accordance with the Securities Act and such state securities laws. If a transfer
of this Note is to be made without registration under the Securities Act (other than in connection
with the initial issuance thereof or a transfer thereof by the Depositor or one of its Affiliates),
then the Note Registrar shall refuse to register such transfer unless it receives (and upon
receipt, may conclusively rely upon) a certificate from the Noteholder desiring to effect such
transfer

A-2-6

 

substantially in the form attached as Exhibit C-1 to the Indenture (which in the case
of Book-Entry Notes, the Note Owner will be deemed to have represented such certification) and a
certificate from such Noteholder’s prospective transferee substantially in the form attached as
Exhibit C-2 to the Indenture (which in the case of the Book-Entry Notes, the Note Owner’s
prospective transferee will be deemed to have represented such certification). None of the Issuer,
the Depositor, the Indenture Trustee or the Note Registrar is obligated to register or qualify any
Notes under the Securities Act or any other securities law or to take any action not otherwise
required under this Indenture to permit the transfer of any Note or interest therein without
registration or qualification. Any Noteholder desiring to effect a transfer of Notes or interests
therein shall, and does hereby agree to, indemnify the Issuer, the Depositor, the Securities
Administrator, the Owner Trustee, the Indenture Trustee and the Note Registrar against any
liability that may result if the transfer is not so exempt or is not made in accordance with such
federal and state laws.

     No transfer of this Note or any interest herein to a Plan subject to ERISA, Section 4975 of
the Code or any Similar Law or any Person acting directly or indirectly on behalf of any such Plan
or any Person using Plan assets to acquire this Note shall be made except in accordance with
Section 2.03(a) of the Indenture.

     The Notes are subject to optional redemption and a clean-up call in accordance with the

agrees that no recourse may be taken, directly or indirectly, with respect to the obligations of
the Issuer, the Owner Trustee, the Securities Administrator or the Indenture Trustee on the Notes
or under the Indenture or any certificate or other writing delivered in connection therewith,
against (i) the Indenture Trustee, the Securities Administrator or the Owner Trustee in their
respective individual capacities, (ii) any owner of a beneficial interest in the Issuer or (iii)
any partner, owner, beneficiary, agent, officer, director or employee of the Indenture Trustee, the

Trustee or of any successor or assign of the Indenture Trustee, the Owner Trustee or the Securities
Administrator in its individual capacity, except as any such Person may have expressly agreed and
except that any such partner, owner or beneficiary shall be fully liable, to the extent provided by
applicable law, for any unpaid consideration for stock, unpaid capital contribution or failure to
pay any installment or call owing to such entity.

     Each Noteholder, by acceptance of a Note or a beneficial interest in a Note, covenants and
agrees by accepting the benefits of the Indenture that such Noteholder will not at any time
institute against the Depositor or the Issuer, or join in any institution against the Depositor or

the then-outstanding Notes by aggregate Class Principal Amount for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of
modifying in any manner the rights of the Noteholders. Any such consent or waiver by the
Noteholder of this Note shall be conclusive and binding upon such Noteholder and upon all future
Noteholders of this Note and of any Note issued upon the registration of transfer hereof or in
exchange hereof or in lieu hereof whether or not notation of such consent or waiver is made upon
this Note. The Indenture also permits the amendment thereof, in certain limited circumstances, or
the waiver of certain terms and conditions set forth in the Indenture, without the consent of
Noteholders of the Notes issued thereunder.

     The term “Issuer” as used in this Note includes any successor to the Issuer under the
Indenture.

     The Notes are issuable only in registered form in denominations as provided in the Indenture,
subject to certain limitations therein set forth.

     THIS NOTE AND THE INDENTURE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF

[NOTE REGISTRAR]

     Re: FBR Securitization Trust 2005-2 Notes ( the “Notes”)

	 	 	Ladies and Gentlemen:

     In connection with the sale by _________(the “Transferor”) to _________
(the “Transferee”) of the Notes having an initial aggregate Note Balance as of September 1, 2005
(the “Closing Date”) of $_________(the “Transferred Notes”). The Notes, including the
Transferred Notes, were issued pursuant to the Indenture, dated as of September 1, 2005 (the
“Indenture”), among FBR Securitization Trust 2005-2 (the “Issuer”), HSBC Bank USA, National
Association (the “Indenture Trustee”) and Wells Fargo Bank, National Association. All capitalized
terms used but not otherwise defined herein shall have the respective meanings set forth in the
Indenture. The Transferor hereby certifies, represents and warrants to you, as Note Registrar, and
for the benefit of the Issuer, the Indenture Trustee and the Transferee, that:

     1 The Transferor is the lawful owner of the Transferred Notes with the full right to
transfer such Notes free from any and all claims and encumbrances whatsoever.

     2 Neither the Transferor nor anyone acting on its behalf has (a) offered, transferred,
pledged, sold or otherwise disposed of any Note, any interest in any Note or any other
similar security to any person in any manner, (b) solicited any offer to buy or accept a
transfer, pledge or other disposition of any Note, any interest in any Note or any other
similar security from any person in any manner, (c) otherwise approached or negotiated with
respect to any Note, any interest in any Note or any other similar security with any person
in any manner, (d) made any general solicitation by means of general advertising or in any
other manner, or (e) taken any other action, which (in the case of any of the acts described
in clauses (a) through (e) hereof) would constitute a distribution of any Note under the
Securities Act of 1933, as amended (the “Securities Act”), or would render the disposition
of any Note a violation of Section 5 of the Securities Act or any state securities laws, or
would require registration or qualification of any Note pursuant to the Securities Act or
any state securities laws.

     3 The Transferor and any person acting on behalf of the Transferor in this matter
reasonably believe that the Transferee is a “qualified institutional buyer” as that term is
defined in Rule 144A (“Rule 144A”) under the Securities Act (a “Qualified Institutional
Buyer”) purchasing for its own account or for the account of a Qualified Institutional
Buyer. In determining whether the Transferee is a Qualified Institutional Buyer, the

C-1-1

 

Transferor and any person acting on behalf of the Transferor in this matter have relied
upon the following method(s) of establishing the Transferee’s ownership and discretionary
investments of securities (check one or more):

	—	 	(a) The Transferee’s most recent publicly available financial statements, which
statements present the information as of a date within 16 months preceding the date of
sale of the Transferred Note in the case of a U.S. purchaser and within 18 months
preceding such date of sale for a foreign purchaser; or
	 
	—	 	(b) The most recent publicly available information appearing in documents filed
by the Transferee with the Securities and Exchange Commission or another United States
federal, state, or local governmental agency or self-regulatory organization, or with a
foreign governmental agency or self-regulatory organization, which information is as of
a date within 16 months preceding the date of sale of the Transferred Note in the case
of a U.S. purchaser and within 18 months preceding such date of sale for a foreign
purchaser; or
	 
	—	 	(c) The most recent publicly available information appearing in a recognized
securities manual, which information is as of a date within 16 months preceding the
date of sale of the Transferred Note in the case of a U.S. purchaser and within 18
months preceding such date of sale for a foreign purchaser; or
	 
	—	 	(d) A certification by the chief financial officer, a person fulfilling an
equivalent function, or other executive officer of the Transferee, specifying the
amount of securities owned and invested on a discretionary basis by the Transferee as
of a specific date on or since the close of the Transferee’s most recent fiscal year,
or, in the case of a Transferee that is a member of a “family of investment companies”,
as that term is defined in Rule 144A, a certification by an executive officer of the
investment adviser specifying the amount of securities owned by the “family of
investment companies” as of a specific date on or since the close of the Transferee’s
most recent fiscal year.

         4 The Transferor and any person acting on behalf of the Transferor understand that in
determining the aggregate amount of securities owned and invested on a discretionary basis
by an entity for purposes of establishing whether such entity is a Qualified Institutional
Buyer:

	—	 	(a) the following instruments and interests shall be excluded: securities of
issuers that are affiliated with the Transferee; securities that are part of an unsold
allotment to or subscription by the Transferee, if the Transferee is a dealer;
securities of issuers that are part of the Transferee’s “family of investment
companies”, if the Transferee is a registered investment company; bank deposit notes
and certificates of deposit; loan participations; repurchase agreements; securities
owned but subject to a repurchase agreement; and currency, interest rate and commodity
swaps;

C-1-2

 

	 	—	 	(b) the aggregate value of the securities shall be the cost of such securities,
except where the entity reports its securities holdings in its financial statements on
the basis of their market value, and no current information with respect to the cost of
those securities has been published, in which case the securities may be valued at
market;
	 
	 	—	 	(c) securities owned by subsidiaries of the entity that are consolidated with
the entity in its financial statements prepared in accordance with generally accepted
accounting principles may be included if the investments of such subsidiaries are
managed under the direction of the entity, except that, unless the entity is a
reporting company under Section 13 or 15(d) of the Securities Exchange Act of 1934, as
amended, securities owned by such subsidiaries may not be included if the entity itself
is a majority-owned subsidiary that would be included in the consolidated financial
statements of another enterprise.

     5 The Transferor or a person acting on its behalf has taken reasonable steps to ensure
that the Transferee is aware that the Transferor is relying on the exemption from the
provisions of Section 5 of the Securities Act provided by Rule 144A.

     6 The Transferor or a person acting on its behalf has furnished, or caused to be
furnished, to the Transferee all information regarding (a) the Transferred Notes and
payments thereon, (b) the nature and performance of the Underlying Certificates and the
Mortgage Loans, (c) the Indenture and the Trust Estate, and (d) any credit enhancement
mechanism associated with the Transferred Notes, that the Transferee has requested.

	 	 	 	 	 
	 	 	Very truly yours,

FBR Securitization Trust 2005-2 (the “Issuer”), HSBC Bank USA, National Association as indenture
trustee (the “Indenture Trustee”), and Wells Fargo Bank, National Association, as securities
administrator. All capitalized terms used herein and not otherwise defined shall have the meanings
set forth in the Indenture. The Transferee hereby certifies, represents and warrants to you, as
Note Registrar, and for the benefit of the Issuer, the Indenture Trustee and the Transferor, that:

     1 If the Transferee is a “qualified institutional buyer” (a “Qualified Institutional
Buyer”) as that term is defined in Rule 144A (“Rule 144A”) under the Securities Act of 1933,
as amended (the “Securities Act”), and has completed one of the forms of certification to
that effect attached hereto as Annex 1 and Annex 2. The Transferee is aware that the sale to
it of the Transferred Notes is being made in reliance on Rule 144A. The Transferee is
acquiring the Transferred Notes for its own account or for the account of a Qualified
Institutional Buyer, and understands that such Transferred Notes may be resold, pledged or
transferred only (i) to a person reasonably believed to be a Qualified Institutional Buyer
that purchases for its own account or for the account of a Qualified Institutional Buyer to
whom notice is given that the resale, pledge or transfer is being made in reliance on Rule
144A, or (ii) pursuant to another exemption from registration under the Securities Act.

     2 The Transferee has been furnished with all information regarding (a) the Transferred
Notes and payments thereon, (b) the nature and performance of the Underlying Certificates
and the Mortgage Loans, (c) the Indenture, and (d) any credit enhancement mechanism
associated with the Transferred Notes, that it has requested.

applicable federal, state or local law (“Similar Law”) materially similar to the
foregoing provisions of ERISA or the Code (each, a “Plan”), nor (2) any Person who
is directly or indirectly purchasing such Note or interest therein on behalf of, or
with “plan assets” of a Plan; or

“plan assets” and represents that the acquisition and holding of the Note or any
interest herein qualifies under a Prohibited Transaction Class Exemption (as defined in
the Indenture) and will not give rise to a nonexempt prohibited transaction under ERISA
or Section 4975 of the Code or similar violation of Similar Law.

     Any Person acquiring or accepting the Note or interest in the Note that is a Book-Entry Note
will be deemed to represent that clause (a) or (b) applies by virtue of its acquisition or
acceptance of such Note or interest therein.

financial statements, a copy of which is attached hereto, as of a

C-2-3

 

	 	 	 	date not more than 16 months preceding the date of sale of the Note in the
case of a U.S. savings and loan association, and not more than 18 months

equivalent institution.

           paragraph and subparagraph under subsection
(a)(1) of Rule 144A pursuant to which it qualifies. Note that registered
investment companies should complete Annex 2 rather than this Annex 1.)

 

 

 

 

     3 The term “securities” as used herein does not include (i) securities of issuers that
are affiliated with the Transferee, (ii) securities that are part of an unsold allotment to
or subscription by the Transferee, if the Transferee is a dealer, (iii) bank deposit notes
and certificates of deposit, (iv) loan participations, (v) repurchase agreements, (vi)

the securities referred to in this paragraph.

     4 For purposes of determining the aggregate amount of securities owned and/or invested
on a discretionary basis by the Transferee, the Transferee used the cost of such securities

C-2-4

 

financial statements on the basis of their market value, and no current information
with respect to the cost of those securities has been published, in which case the
securities were valued at market. Further, in determining such aggregate amount, the
Transferee may have included securities owned by subsidiaries of the Transferee, but only if
such subsidiaries are consolidated with the Transferee in its financial statements prepared
in accordance with generally accepted accounting principles and if the investments of such
subsidiaries are managed under the Transferee’s direction. However, such securities were not
included if the Transferee is a majority-owned, consolidated subsidiary of another
enterprise and the Transferee is not itself a reporting company under the Securities
Exchange Act of 1934, as amended.

     5 The Transferee acknowledges that it is familiar with Rule 144A and understands that
the Transferor and other parties related to the Transferred Notes are relying and will
continue to rely on the statements made herein because one or more sales to the Transferee
may be in reliance on Rule 144A.

	 	 	 	 	 	 	 
	 

	 	Yes
	 	No
	 	Will the Transferee be purchasing the Transferred Notes only for the Transferee’s own account?

     6 If the answer to the foregoing question is “no”, then in each case where the
Transferee is purchasing for an account other than its own, such account belongs to a third
party that is itself a “qualified institutional buyer” within the meaning of Rule 144A, and
the “qualified institutional buyer” status of such third party has been established by the
Transferee through one or more of the appropriate methods contemplated by Rule 144A.

     7 The Transferee will notify each of the parties to which this certification is made of
any changes in the information and conclusions herein. Until such notice is given, the
Transferee’s purchase of the Transferred Notes will constitute a reaffirmation of this
certification as of the date of such purchase. In addition, if the Transferee is a bank or
savings and loan as provided above, the Transferee agrees that it will furnish to such
parties any updated annual financial statements that become available on or before the date
of such purchase, promptly after they become available.

ANNEX 2 to EXHIBIT C-2

QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

[for Transferees that are Registered Investment Companies]

The undersigned hereby certifies as follows to [name of Transferor] (the “Transferor”) and [name of
Note Registrar], as Note Registrar, with respect to the Notes being transferred (the “Transferred
Notes”) as described in the Transferee Certificate to which this certification relates and to which
this certification is an Annex:

     1 As indicated below, the undersigned is the chief financial officer, a person
fulfilling an equivalent function, or other executive officer of the entity purchasing the
Transferred Certificates (the “Transferee”) or, if the Transferee is a “qualified
institutional buyer” as that term is defined in Rule 144A under the Securities Act of 1933,
as amended (“Rule 144A”), because the Transferee is part of a Family of Investment Companies
(as defined below), is an executive officer of the investment adviser (the “Adviser”).

     2 The Transferee is a “qualified institutional buyer” as defined in Rule 144A because
(i) the Transferee is an investment company registered under the Investment Company Act of
1940, as amended, and (ii) as marked below, the Transferee alone owned and/or invested on a
discretionary basis, or the Transferee’s Family of Investment Companies owned, at least
$100,000,000 in securities (other than the excluded securities referred to below) as of the
end of the Transferee’s most recent fiscal year. For purposes of determining the amount of
securities owned by the Transferee or the Transferee’s Family of Investment Companies, the
cost of such securities was used, unless the Transferee or any member of the Transferee’s
Family of Investment Companies, as the case may be, reports its securities holdings in its
financial statements on the basis of their market value, and no current information with
respect to the cost of those securities has been published, in which case the securities of
such entity were valued at market.

	 	—	 	The Transferee owned and/or invested on a discretionary basis $___in
securities (other than the excluded securities referred to below) as of the end of the
Transferee’s most recent fiscal year (such amount being calculated in accordance with
Rule 144A).
	 
	 	—	 	The Transferee is part of a Family of Investment Companies which owned in the
aggregate $___in securities (other than the excluded securities referred to
below) as of the end of the Transferee’s most recent fiscal year (such amount being
calculated in accordance with Rule 144A).

     3 The term “Family of Investment Companies” as used herein means two or more registered
investment companies (or series thereof) that have the same investment adviser or investment
advisers that are affiliated (by virtue of being majority owned

C-2-6

 

subsidiaries of the same parent or because one investment adviser is a majority owned
subsidiary of the other).

     4 The term “securities” as used herein does not include (i) securities of issuers that
are affiliated with the Transferee or are part of the Transferee’s Family of Investment
Companies, (ii) bank deposit notes and certificates of deposit, (iii) loan participations,
(iv) repurchase agreements, (v) securities owned but subject to a repurchase agreement and
(vi) currency, interest rate and commodity swaps. For purposes of determining the aggregate
amount of securities owned and/or invested on a discretionary basis by the Transferee, or
owned by the Transferee’s Family of Investment Companies, the securities referred to in this
paragraph were excluded.

     5 The Transferee is familiar with Rule 144A and understands that the parties to which
this certification is being made are relying and will continue to rely on the statements
made herein because one or more sales to the Transferee will be in reliance on Rule 144A.

	 	 	 	 	 	 	 
	 

	 	Yes
	 	No
	 	Will the Transferee be purchasing the Transferred Notes only for the Transferee’s own account?

     6 If the answer to the foregoing question is “no”, then in each case where the
Transferee is purchasing for an account other than its own, such account belongs to a third
party that is itself a “qualified institutional buyer” within the meaning of Rule 144A, and
the “qualified institutional buyer” status of such third party has been established by the
Transferee through one or more of the appropriate methods contemplated by Rule 144A.

     7 The undersigned will notify the parties to which this certification is made of any
changes in the information and conclusions herein. Until such notice, the Transferee’s
purchase of the Transferred Notes will constitute a reaffirmation of this certification by
the undersigned as of the date of such purchase.

is incorporated in and made a part of this Indenture. Notes issued in definitive

without the Global Note Legend thereon and without the "Schedule of Exchanges of
Interests in the Global Note" attached thereto). Each Global Note shall
represent such of the outstanding Notes as shall be specified therein and each

outstanding Notes from time to time endorsed thereon and that the aggregate
principal amount of outstanding Notes represented thereby may from time to time

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

Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any
securities exchange or automated quotation system on which the Notes may be
listed or designated for issuance, or to conform to usage.

     The terms and provisions contained in the form of Note attached as Exhibit
A hereto shall constitute, and are hereby expressly made, a part of this
Indenture and to the extent applicable, the Company and the Trustee, by their
execution and delivery of this Indenture, expressly agree to such terms and
provisions and to be bound thereby.

     (b) Members of, or Participants in, the Depositary ("Agent Members") shall

(including, for this purpose, its nominee) may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner and
holder of such Global Note for all purposes whatsoever. Notwithstanding the
foregoing, nothing

                                       9
<PAGE>
herein shall (i) 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 (ii) impair, as between the
Depositary and its Agent Members, the operation of customary practices governing
the exercise of the rights of a beneficial holder of any Note.

     Section 2.3 Date and Denomination of Notes; Payments of Interest

     The Notes shall be issuable in registered form without coupons in
denominations of One Thousand United States Dollars ($1,000) principal amount
and integral multiples thereof. Every Note shall be dated the date of its
authentication, and shall bear interest on the principal sum outstanding from
time to time under the Note, at the rate per annum specified in the title of the
form of Note attached as Exhibit A hereto, accrued from the most recent date to
which interest has been paid or, if no interest has been paid, from the date of
issuance of the Note and payable semi-annually on April 15 and October 15 of
each year (each, an "Interest Payment Date"), commencing April 15, 2006, as
specified on the face of the form of Note attached as Exhibit A hereto. Each
payment of interest on the Notes shall include interest to, but excluding, the
date of such payment. Interest on the Notes shall be deemed to have commenced
accruing on October 7, 2005. Interest on the Notes shall be computed on the
basis of a 360-day year comprised of twelve 30-day months. Any accrued and
unpaid interest which is not paid within five (5) Business Days of the Interest
Payment Date on which such payment of interest was due shall bear interest at
the rate of 6% per annum from such Interest Payment Date until the same is paid
in full (or, if less, the maximum interest rate then permitted by applicable
law) (the "Default Interest").

     The Person in whose name any Note, or portion thereof (or its Predecessor
Note) is registered at the close of business on any record date with respect to
any Interest Payment Date (including any Note that is converted after the record
date and on or before the Interest Payment Date) shall (except as otherwise
provided in Section 15.3 with respect to Automatic Conversions of Notes or
portions thereof) be entitled to receive the interest payable on such Interest
Payment Date notwithstanding the cancellation of such Note upon any transfer,
exchange, redemption or conversion subsequent to the record date and on or prior
to such Interest Payment Date. Interest may, at the option of the Company, be
paid by check mailed to the address of such Person on the Note Register;
provided that, with respect to any holder of Notes with an aggregate principal
amount equal to or in excess of Five Hundred Thousand United States Dollars
($500,000), interest on such holder's Notes shall be paid by wire transfer in
immediately available funds to any bank located in the United States in
accordance with the wire transfer instruction supplied by such holder from time
to time to the Trustee and paying agent (if different from Trustee) in writing
at least five (5) Business Days prior to the applicable record date. The term
"record date" with respect to any Interest Payment Date shall mean the 4th day
of the month in which the Interest Payment Date shall occur, whether or not such
date is a Business Day.

     If the Company defaults in a payment of interest on the Notes, it shall pay
the defaulted interest in any lawful manner plus, to the extent lawful, the
Default Interest, to the Persons who are holders on a subsequent special record
date. The Company shall promptly notify the Trustee in writing of the amount of
defaulted interest proposed to be paid on each Note and the date of the proposed
payment. The Company shall fix or cause to be fixed each such special record
date and

                                       10
<PAGE>
payment date, provided that no such special record date shall be less than ten
(10) days prior to the related payment date for such defaulted interest. At
least fifteen (15) days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) shall send or cause to be sent to holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

     Section 2.4 Execution of Notes

     The Notes shall be signed in the name and on behalf of the Company by the
facsimile signature of its President, its Chief Executive Officer, or any of its
Vice Presidents, and attested by the facsimile signature of its Chief Financial
Officer, Treasurer or its Assistant Treasurer, or Secretary or any of its
Assistant Secretaries (which may be printed, engraved or otherwise reproduced
thereon, by facsimile or otherwise). Only such Notes as shall bear thereon a
certificate of authentication substantially in the form set forth on the form of
Note attached as Exhibit A hereto, manually executed by the Trustee (or an
authenticating agent appointed by the Trustee as provided by Section 17.10),
shall be entitled to the benefits of this Indenture or be valid or obligatory
for any purpose. Such certificate by the Trustee (or such authenticating agent)
upon any Note executed by the Company shall be conclusive evidence that the Note
so authenticated has been duly authenticated and delivered hereunder and that
the holder thereof is entitled to the benefits of this Indenture.

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

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

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

     (b) Transfer and Exchange of Global Notes. A Global Note may not be
transferred as a whole except by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. All Global Notes will be exchanged by
the Company for Definitive Notes only if (i) the Company delivers to the Trustee

                                       11
<PAGE>
notice from the Depositary that it is unwilling or unable to continue to act as
Depositary or that it is no longer a clearing agency registered under the
Exchange Act and, in either case, a successor Depositary is not appointed by the
Company within 120 days after the date of such notice from the Depositary or
(ii) the Company in its sole discretion determines that the Global Notes (in
whole but not in part) should be exchanged for Definitive Notes and delivers a
written notice to such effect to the Trustee. Upon the occurrence of either of
the preceding events in (i) or (ii) above, Definitive Notes shall be issued in
such names and in an aggregate principal amount equal to that of the Global
Notes so exchanged as the Depositary shall instruct the Trustee. Global Notes
also may be exchanged or replaced, in whole or in part, as provided in Sections
2.6 and 2.7. Every Note authenticated and delivered in exchange for, or in lieu
of, a Global Note or any portion thereof pursuant to Section 2.6 or 2.7 shall be
authenticated and delivered in the form of, and shall be, a Global Note. A
Global Note may not be exchanged for another Note other than as provided in this
Section 2.5(b), however, beneficial interests in a Global Note may be
transferred and exchanged as provided in Section 2.5(c).

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

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

          (iii) Transfer of Beneficial Interests to Another Restricted Global
     Note. A beneficial interest in any Restricted Global Note may be

     Registrar receives the following:

               (A) if the transferee will take delivery in the form of a

          certifications in item (1)(a) thereof; or

               (B) if the holder of such beneficial interest in a Restricted

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

          and, in each case set forth above (other than a transfer pursuant to

          Counsel in form reasonably acceptable to the Note Registrar to the
          effect that such exchange or transfer is in compliance with the

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

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

aggregate principal amount equal to the aggregate principal amount of beneficial
interests transferred pursuant to subparagraph (B) above.

owner requests, in accordance with the Applicable Procedures, that such
beneficial owner's beneficial interest be transferred in connection with such an
exchange, or that such beneficial owner's beneficial interest be exchanged for
an Unrestricted Definitive Note or Notes, then such request shall also be
subject to the applicable requirements of this Section 2.5(d).

               (i) Beneficial Interests in Restricted Global Notes to Restricted
          Definitive Notes. If a holder of a beneficial interest in a Restricted
          Global Note proposes to transfer such beneficial interest to a Person

     Company shall execute and the Trustee shall authenticate and deliver to the
     Person designated in the instructions a Definitive Note in the appropriate
     principal amount. Any Definitive Note issued in exchange for a

<PAGE>
     beneficial interest in a Restricted Global Note pursuant to this Section
     2.5(d) shall be registered in such name or names and in such authorized
     denomination or denominations as the holder of such beneficial interest
     shall instruct the Note Registrar through instructions from the Depositary
     and the Participant or Indirect Participant. The Trustee shall deliver such
     Definitive Notes to the Persons in whose names such Notes are so
     registered. Any Definitive Note issued in exchange for a beneficial
     interest in a Restricted Global Note pursuant to this Section 2.5(d)(i)

          Unrestricted Definitive Note or Notes or may transfer such beneficial
          interest to a Person who takes delivery thereof in the form of an
          Unrestricted Definitive Note only if the Note Registrar receives the
          following:

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

                    (B) if the holder of such beneficial interest in a

               holder in the form of Exhibit D hereto, including the one of the
               certifications in item (3) thereof;

          and, in each case set forth above (other than a transfer pursuant to
          an effective registration statement), if the Note Registrar so
          requests or if the Applicable Procedures so require, an Opinion of
          Counsel in form reasonably acceptable to the Note Registrar to the
          effect that such exchange or transfer is in compliance with the
          Securities Act and that the restrictions on transfer contained herein
          and in the Private Placement Legend are no longer required in order to

               (iii) Beneficial Interests in Unrestricted Global Notes to
          Unrestricted Definitive Notes. If any holder of a beneficial interest
          in an Unrestricted Global Note proposes to transfer such beneficial

          designated in the instructions an Unrestricted Definitive Note in the
          appropriate principal amount. Any Definitive Note issued in exchange
          for a beneficial interest pursuant to this Section 2.5(d)(iii) shall
          be registered in such name or names and in such authorized
          denomination or denominations as the holder of such

          beneficial interest shall instruct the Note Registrar through
          instructions from the Depositary and the Participant or Indirect
          Participant. The Trustee shall deliver such Unrestricted Definitive
          Notes to the Persons in whose names such Notes are so registered. Any

               proposes to transfer such Note to a Person who shall take
               delivery thereof in the form of an Unrestricted Definitive Note,
               a certificate from such holder in the form of Exhibit D hereto,
               including the certifications in item (3) thereof, as applicable;

          and, in each such case set forth in this subparagraph (B), if the Note
          Registrar so requests, an Opinion of Counsel in form reasonably
          acceptable to the Company to the effect that such exchange or transfer
          is in compliance with the Securities Act and that the restrictions on

     A holder of Unrestricted Definitive Notes may transfer such Notes to a
     Person who takes delivery thereof in the form of an Unrestricted Definitive

     collectively, the "Restricted Securities") shall be subject to the
     restrictions on transfer set forth in this Section 2.5(h)(i) (including the
     legend set forth below), unless such restrictions on transfer shall be
     waived by written consent of the Company, and the holder of each such
     Restricted Security, by such holder's acceptance thereof, agrees to be
     bound by all such restrictions on transfer. As used in Sections 2.5(h)(i)
     and 2.5(h)(ii), the term "transfer" encompasses any sale, transfer or other
     disposition (excluding any pledge unless or until any foreclosure on such
     pledge) whatsoever of any Restricted Security.

          Subject to Section 5 of the Securities Purchase Agreement, until two
     (2) years after the original issuance date of any Note, any certificate
     evidencing such Note (and all securities issued in exchange therefor or
     substitution thereof, other than Common Stock, if any, issued upon
     conversion thereof which shall bear the legend set forth in Section
     2.5(h)(ii), if applicable) shall bear a legend in substantially the
     following form (unless such Note has been transferred pursuant to a
     registration statement that has been declared effective under the
     Securities Act (and which continues to be effective at the time of such
     transfer), or the Note has been transferred pursuant to the exemption from
     registration provided by Rule 144 under the Securities Act, or unless
     otherwise agreed by the Company in writing, with notice thereof to the
     Trustee):

          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
          "SECURITIES ACT") OR APPLICABLE STATE SECURITIES LAWS. THIS SECURITY
          MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE
          ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES
          UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS OR AN
          EXEMPTION THEREFROM.

          Any Note (or security issued in exchange or substitution therefor) as
     to which such restrictions on transfer shall have expired in accordance
     with their terms may, upon surrender of such Note for exchange to the Note
     Registrar in accordance with the provisions of this Section 2.5, be
     exchanged for a new Note or Notes, of like tenor and aggregate principal
     amount, which shall not bear the restrictive legend required by this
     Section 2.5(h)(i).

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

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
          "SECURITIES ACT") OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES
          MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE
          ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES
          UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS OR AN
          EXEMPTION THEREFROM.

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

          (iii) Global Note Legend. Each Global Note shall bear a legend in

          UNLESS THIS NOTE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
          DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO THE
          ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT,
          AND ANY NOTE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH
          OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND
          ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS
          REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER,
          PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
          IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS
          AN INTEREST HEREIN.

     (i) Resale of Notes Purchased by the Company or an Affiliate. Any Note or
Common Stock issued upon the conversion or exchange of a Note that, prior to the
expiration of the holding

                                       19
<PAGE>
period applicable to sales thereof under Rule 144(k) under the Securities Act
(or any successor rule), is purchased or owned by the Company or any Affiliate
thereof may not be resold by the Company or such Affiliate unless registered
under the Securities Act or resold pursuant to an exemption from the
registration requirements of the Securities Act in a transaction that results in
such Notes or Common Stock, as the case may be, no longer being "restricted
securities" (as defined under Rule 144).

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

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

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

                                       20
<PAGE>
of a beneficial interest in another Global Note, such other Global Note shall be
increased accordingly and an endorsement shall be made on such Global Note by
the Trustee or by the Depositary at the direction of the Trustee to reflect such
increase.

     Section 2.6 Mutilated, Destroyed, Lost or Stolen Notes

     In case any Note shall become mutilated or be destroyed, lost or stolen,
the Company in its discretion may execute, and upon its request the Trustee or
an authenticating agent appointed by the Trustee shall authenticate and deliver,
a new Note, bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated Note, or in lieu of and in substitution for the
Note so destroyed, lost or stolen. In every case the applicant for a substituted
Note shall furnish to the Company, to the Trustee and, if applicable, to such
authenticating agent such security or indemnity as reasonably required by them
to save each of them harmless for any loss, liability, cost or expense caused by
or connected with such substitution, and, in every case of destruction, loss or
theft, the applicant shall also furnish to the Company, to the Trustee and, if
applicable, to such authenticating agent evidence to their reasonable
satisfaction of the destruction, loss or theft of such Note and of the ownership
thereof.

     The Trustee or such authenticating agent may authenticate any such
substituted Note and deliver the same upon the receipt of such security or
indemnity as the Trustee, the Company and, if applicable, such authenticating
agent may reasonably require. Upon the issuance of any substituted Note, the
Company may require the payment by the holder of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other expenses connected therewith. Once any substitute Note has been issued
pursuant to this Section 2.6, the original Note being replaced by such
substitute Note shall automatically be deemed canceled. In case any Note which
has matured or is about to mature or has been called for redemption or is about
to be converted into Common Stock shall become mutilated or be destroyed, lost
or stolen, the Company may, instead of issuing a substitute Note, pay or
authorize the payment of or convert or authorize the conversion of the same
(without surrender thereof except in the case of a mutilated Note), as the case
may be, if the applicant for such payment or conversion shall furnish to the
Company, to the Trustee and, if applicable, to such authenticating agent such
security or indemnity as may be reasonably required by them to save each of them
harmless for any loss, liability, cost or expense caused by or connected with
such substitution, and, in case of destruction, loss or theft, evidence
reasonably satisfactory to the Company, the Trustee and, if applicable, any
paying agent or conversion agent of the destruction, loss or theft of such Note
and of the ownership thereof.

     Every substitute Note issued pursuant to the provisions of this Section 2.6
by virtue of the fact that any Note is destroyed, lost or stolen shall
constitute an additional contractual obligation of the Company, whether or not
the destroyed, lost or stolen Note shall be found at any time, and shall be
entitled to all the benefits of (but shall be subject to all the limitations set
forth in) this Indenture equally and proportionately with any and all other
Notes duly issued hereunder. To the extent permitted by law, all Notes shall be
held and owned upon the express condition that the foregoing provisions are
exclusive with respect to the replacement or payment or conversion of mutilated,
destroyed, lost or stolen Notes and shall preclude any and all other rights or
remedies notwithstanding any law or statute existing or hereafter enacted to the
contrary with respect to the

                                       21
<PAGE>
replacement or payment or conversion of negotiable instruments or other
securities without their surrender.

     Section 2.7 Temporary Notes

     Pending the preparation of definitive Notes, the Company may execute and
the Trustee or an authenticating agent appointed by the Trustee shall, upon
written request of the Company, authenticate and deliver temporary Notes
(printed or lithographed). Temporary Notes shall be issuable in any authorized
denomination, and substantially in the form of the Global Notes or the
Definitive Notes, as the case may be, but with such omissions, insertions and
variations as may be appropriate for temporary Notes, all as may be determined
by the Company. Every such temporary Note shall be executed by the Company and
authenticated by the Trustee or such authenticating agent upon the same
conditions and in substantially the same manner, and with the same effect, as
the Definitive Notes or Global Notes. Without unreasonable delay the Company
will execute and deliver to the Trustee or such authenticating agent Definitive
Notes and Global Notes and thereupon any or all temporary Notes may be
surrendered in exchange for the applicable replacement Note, at each office or
agency maintained by the Company pursuant to Section 5.2 and the Trustee or such
authenticating agent shall authenticate and deliver in exchange for such
temporary Notes an equal aggregate principal amount of Definitive Notes or
Global Notes, as the case may be. Such exchange shall be made by the Company at
its own expense and without any charge therefor. Until so exchanged, the
temporary Notes shall in all respects be entitled to the same benefits and
subject to the same limitations under this Indenture as Definitive Notes or
Global Notes, as the case may be, authenticated and delivered hereunder.

     Section 2.8 Cancellation of Notes Paid, Etc.

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

     Section 2.9 CUSIP Numbers

     The Company in issuing the Notes shall use "CUSIP" numbers and the Trustee
shall use "CUSIP" numbers in notices of redemption as a convenience to holders;
provided that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Notes or as contained in
any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Notes, and any such redemption shall not
be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee of any change in the "CUSIP" numbers.

                                       22
<PAGE>
     Section 2.10 Calculation of Original Issue Discount

     The Company shall file with the Trustee promptly at the end of each
calendar year (i) a written notice specifying the amount of original issue
discount (including daily rates and accrual periods) accrued on the Notes as of
the end of such year and (ii) such other specific information relating to such
original issue discount as may then be relevant under the Internal Revenue Code
of 1986, as amended from time to time.

                                   ARTICLE III

                          OPTIONAL REDEMPTION OF NOTES

     Section 3.1 Redemption Price

     From and after October 20, 2008 the Company may, at its option, redeem all
or any part of the Notes, upon notice as set forth in Section 3.2, and the
Company shall pay each holder of Notes redeemed a redemption price equal to the
principal amount of such Notes, plus accrued and unpaid interest thereon, if
any, to, but excluding, the date of redemption (subject to the provisions of the
first paragraph of Section 3.3); provided that, to the extent that the
Registration Statement is required by the terms of the Registration Rights
Agreement to remain effective as of the date that notice of redemption is
provided in accordance with Section 3.2, the Registration Statement is effective
and available during the 30 day period prior to the giving of such notice and at
all times from the date of such notice until the earlier of 30 days following
the redemption date or the last date on which the Registration Statement is
required to remain effective. The Company may only elect to redeem all or any
part of the Notes if it has, as of the date of the notice of redemption required
by Section 3.2, sufficient shares of Common Stock authorized and available for
issuance to enable the holders of all of the Notes (or parts thereof) called for
redemption to convert such Notes (or parts thereof) into Common Stock pursuant
to Section 15.1.

     Section 3.2 Notice of Redemption; Selection of Notes

     In case the Company shall desire to exercise the right to redeem all or, as
the case may be, any part of the Notes pursuant to Section 3.1, it shall fix a
date for redemption, and it, or at its request (which must be received by the
Trustee at least ten (10) Business Days prior to the date the Trustee is
requested to give notice as described below unless a shorter period is agreed to
by the Trustee), the Trustee in the name of and at the expense of the Company,
shall send or cause to be sent a notice of such redemption at least twenty (20)
and not more than ninety (90) days prior to the date fixed for redemption (the
"Redemption Date") to the holders of Notes so to be redeemed as a whole or in
part at their last addresses as the same appear on the Note Register (provided
that if the Company shall give such notice, it shall also give such notice, and
notice of the aggregate amount of Notes to be redeemed, to the Trustee). Such
notice shall be irrevocable. The notice if sent in the manner herein provided
shall be conclusively presumed to have been duly given, whether or not the
holder receives such notice. In any case, failure to give such notice or any
defect in the notice to the holder of any Note designated for redemption as a
whole or in part shall not affect the validity of the proceedings for the
redemption of any other Note.

                                       23
<PAGE>
     Each such notice of redemption shall specify the aggregate principal amount
of Notes to be redeemed, the "CUSIP" number or numbers of such Notes, the
Redemption Date, the redemption price at which Notes are to be redeemed, the
place or places of payment, that payment will be made upon presentation and
surrender of such Notes, that interest accrued to, but excluding, the Redemption
Date will be paid as specified in said notice, and that on and after said date
interest thereon or on the portion thereof to be redeemed will cease to accrue.
Such notice shall also state the current Conversion Price and the date on which
the right to convert such Notes or portions thereof into Common Stock will
expire, which shall be the close of business on the last Business Day prior to
the Redemption Date. If fewer than all the Notes are to be redeemed, the notice
of redemption shall identify the Notes to be redeemed. In case any Note is to be
redeemed in part only, the notice of redemption shall state the portion of the
principal amount thereof to be redeemed and shall state that on and after the
Redemption Date, upon surrender of such Note, a new Note or Notes in principal
amount equal to the unredeemed portion thereof will be issued.

     On or prior to the Redemption Date, the Company will deposit with the
Trustee or with one or more paying agents (or, if the Company is acting as its
own paying agent, set aside, segregate and hold in trust as provided in Section
5.4) an amount of money sufficient to redeem on the Redemption Date all the
Notes (or portions thereof) so called for redemption (other than those
theretofore surrendered for conversion into Common Stock) at the appropriate
redemption price, together with accrued interest to, but excluding, the
Redemption Date; provided that if such deposit is made on the Redemption Date it
must be received by the Trustee or paying agent, as the case may be, by 1:00
p.m. Minneapolis time, on such date. If any Note called for redemption is
converted pursuant hereto, any money deposited with the Trustee or any paying
agent or so segregated and held in trust for the redemption of such Note shall
be paid to the Company upon its request, or, if then held by the Company shall
be discharged from such trust.

     If fewer than all the Notes are to be redeemed, the Company will give the
Trustee written notice in the form of an Officer's Certificate not fewer than
forty-five (45) days (or such shorter period of time as may be acceptable to the
Trustee) prior to the Redemption Date as to the aggregate principal amount of
Notes to be redeemed, and the Company, or at its request, the Trustee in the
name of and at the expense of the Company, shall give the holders at least
twenty (20) days' notice in advance of the Redemption Date as to the aggregate
principal amount of Notes to be redeemed. If fewer than all the Notes are to be
redeemed, the Trustee, subject to any applicable rules of the Depositary, shall
select the Notes or portions thereof to be redeemed (in principal amounts of One
Thousand United States Dollars ($1,000) or integral multiples thereof), on a pro
rata basis, by lot or by any other method that the Trustee considers fair and
appropriate. If any Note selected for partial redemption is converted in part
after such selection, the converted portion of such Note shall be deemed (so far
as is possible) to be the portion to be selected for redemption. The Notes (or
portions thereof) so selected shall be deemed duly selected for redemption for
all purposes hereof, notwithstanding that any such Note is converted as a whole
or in part before the sending of the notice of redemption.

     Upon any redemption of less than all Notes, the Company and the Trustee may
(but need not) treat as outstanding any Notes surrendered for conversion during
the period of fifteen (15) days next preceding the sending of a notice of
redemption and may (but need not) treat as not outstanding any

                                       24
<PAGE>
Note authenticated and delivered during such period in exchange for the
unconverted portion of any Note converted in part during such period.

     Section 3.3 Payment of Notes Called for Redemption

     If notice of redemption has been given as above provided, the Notes or
portion of Notes with respect to which such notice has been given shall, unless
converted into Common Stock pursuant to the terms hereof, become due and payable
on the date and at the place or places stated in such notice at the applicable
redemption price, and interest accrued to, but excluding, the Redemption Date,
and on and after said date (unless the Company shall default in the deposit of
the amount of money sufficient to redeem such Notes) interest on the Notes or
portion of Notes so called for redemption shall cease to accrue and such Notes
shall cease at the close of business on the last Business Day prior to the
Redemption Date to be convertible into Common Stock and, except as provided in
Sections 8.5 and 13.4, to be entitled to any benefit or security under this
Indenture, and the holders thereof shall have no right in respect of such Notes
except the right to receive the redemption price thereof and unpaid interest to,
but excluding, the Redemption Date. On presentation and surrender of such Notes
at a place of payment specified in said notice, the said Notes or the specified
portions thereof to be redeemed shall be paid and redeemed by the Company at the
applicable redemption price and interest accrued thereon to, but excluding, the
Redemption Date; provided that, if the applicable Redemption Date falls after
the record date for an Interest Payment Date and before the relevant Interest
Payment Date, the semi-annual payment of interest becoming due on such Interest
Payment Date shall be paid to the holders of such Notes registered as such on
the relevant record date in the manner provided in Section 2.3 and shall not be
paid to the holders surrendering the Notes when they do so.

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

     Notwithstanding the foregoing, the Company shall not redeem any Notes or
send any notice of optional redemption during the continuance of a default in
payment of interest or premium on the Notes or of any Event of Default.

     Section 3.4 Conversion Arrangement on Call for Redemption

     In connection with any redemption of Notes, the Company may arrange for the
purchase and conversion of any Notes not converted prior to the expiration of
such conversion right by an agreement with one or more investment bankers or
other purchasers to purchase such Notes by paying to the Trustee in trust for
the Noteholders, on or before the Redemption Date, an amount not less than the
applicable redemption price and interest accrued to the Redemption Date, of such
Notes. Notwithstanding anything to the contrary contained in this Article III,
the obligation of the Company to pay the redemption price of such Notes and
interest accrued to, but excluding, the Redemption Date, shall be deemed to be
satisfied and discharged to the extent such amount is so paid by such purchasers
to such Noteholders. If such an agreement is entered into, a copy of which,

                                       25
<PAGE>
certified as true and correct by the Secretary or Assistant Secretary of the
Company will be filed with the Trustee prior to the Redemption Date, any Notes
not duly surrendered for conversion by the holders thereof may, at the option of
the Company, be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such holders and (notwithstanding anything to the contrary
contained in Article XV) surrendered by such purchasers for conversion, all as
of immediately prior to the close of business on the Redemption Date (and the
right to convert any such Notes shall be deemed to have been extended through
such time), subject to payment of the above amount as aforesaid. At the written
direction of the Company, the Trustee shall hold and dispose of any such amount
paid to it in the same manner as it would monies deposited with it by the
Company for the redemption of Notes.

                                   ARTICLE IV

                       PARTICULAR COVENANTS OF THE COMPANY

     Section 5.1 Payment of Principal, Premium and Interest

     The Company covenants and agrees that it will duly and punctually pay or
cause to be paid the principal of and premium, if any, and interest on each of
the Notes at the places, at the respective times and in the manner provided
herein and in the Notes. Liquidated Damages paid pursuant to Section 15.2, if
any, shall be paid within ten (10) Business Days after the end of each month
with respect to which such liquidated damages have accrued pursuant to Section
15.2 in the same manner as interest is paid pursuant to Section 2.3. Liquidated
Damages on the Notes paid pursuant to Section 2(f) of the Registration Rights
Agreement, if any, shall be paid at the times and in the manner provided
therein. All payments shall be considered made on the date due if on such date
the Company has deposited (in the manner provided in Sections 3.2 and 5.4(a))
with the Trustee or with one or more paying agents (or, if the Company is acting
as its own paying agent, has set aside, segregated and is holding in trust as
provided in Section 5.4) an amount of money sufficient to make such payment.

     Section 5.2 Maintenance of Office or Agency

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

                                       26
<PAGE>
     The Company may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations; provided that no
such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in Minneapolis, Minnesota, for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

     The Company hereby initially designates the Trustee as paying agent, Note
Registrar, Custodian and conversion agent and the office or agency of the
Trustee in Minneapolis, Minnesota (which initially shall be the Corporate Trust
Office of the Trustee), as one such office or agency of the Company for each of
the aforesaid purposes.

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

     Section 5.3 Appointments to Fill Vacancies in Trustee's Office The Company,
whenever necessary to avoid or fill a vacancy in the office of Trustee, will
appoint, in the manner provided in Section 8.10, a Trustee, so that there shall
at all times be a Trustee hereunder.

     Section 5.4 Provisions as to Paying Agent

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

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

          (2) that it will give the Trustee notice of any failure by the Company
     (or by any other Person) to make any payment of the principal of and
     premium, if any, or interest (including Liquidated Damages, if any) on the
     Notes when the same shall be due and payable; and

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

     The Company shall, on or before each due date of the principal of, premium,
if any, or interest on the Notes, deposit with the paying agent a sum sufficient
to pay such principal, premium, if any, or interest, and (unless such paying
agent is the Trustee) the Company will promptly notify the Trustee of any
failure to take such action, provided that if such deposit is made on the due
date, such deposit must be received by the paying agent by 10:00 a.m.,
Minneapolis time, on such date.

                                       27
<PAGE>
     (b) If the Company shall act as its own paying agent, it will, on or before
each due date of the principal of, premium, if any, or interest (including
Liquidated Damages, if any) on the Notes, set aside, segregate and hold in trust
for the benefit of the holders of the Notes a sum sufficient to pay such
principal, premium, if any, or interest (including Liquidated Damages, if any)
so becoming due and will notify the Trustee of any failure to take such action
and of any failure by the Company (or any other Person) to make any payment of
the principal of, premium, if any, or interest (including Liquidated Damages, if
any) on the Notes when the same shall become due and payable.

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

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

     Section 5.5 Existence

necessary to preserve and keep in full force and effect its corporate existence.

     Section 5.6 Information Requirement

     Within the period prior to the expiration of the holding period applicable
to sales thereof under Rule 144(k) under the Securities Act (or any successor
provision), the Company covenants and agrees that it shall, during any period in
which it is not subject to Section 13 or 15(d) under the Exchange Act, make
available to any holder or beneficial holder of Notes which continue to be
Restricted Securities, in connection with any sale thereof and any prospective
purchaser of Notes from such holder or beneficial holder, the information
required pursuant to Rule 144A(d)(4) under the Securities Act upon the request
of any holder or beneficial holder of the Notes and it will take such further
action as any holder or beneficial holder of such Notes may reasonably request
in connection with qualification of such sale for exemption from registration
under Rule 144A.

     Section 5.7 Stay, Extension and Usury Laws

     The Company covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law or other law
that would prohibit or forgive the Company from paying all or any portion of the
principal of or interest on the Notes as contemplated herein, wherever enacted,
now or at any time hereafter in force, or which may affect the covenants or the
performance of this Indenture; and the Company (to the extent it may lawfully do
so) hereby expressly waives all benefit or advantage of any such law, and
covenants that it will not, by resort to any such law, hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law has been enacted.

     Section 5.8 Compliance Certificate

     The Company shall deliver to the Trustee within one hundred twenty (120)
days after the end of each fiscal year of the Company (beginning with the fiscal
year ending on December 31, 2005) an Officer's Certificate, signed by the
principal executive, principal financial officer or principal accounting officer
of the Company, stating whether or not the signers know of any default or Event
of Default that occurred during such period. Such Officer's Certificate shall
describe in reasonable detail the default or Event of Default, if any, and its
status.

     Section 5.9 Further Instruments and Acts

further instruments and do such further acts as may be reasonably necessary or
proper to carry out more effectively the purposes of this Indenture.

when the Notes are listed on any stock exchange or automated quotation system
and when any such listing is discontinued.

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

     Section 5.11 Limitation on Indebtedness

     Unless and until the aggregate principal amount of Notes outstanding is
less than $5 million, the Company shall not, directly or indirectly, create,
incur, issue, assume, guaranty or otherwise become directly or indirectly
liable, contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness that is senior to or on a par with the Notes in an aggregate
principal amount outstanding in excess of $12 million, without the prior consent
of holders of a majority in aggregate principal amount of the Notes then
outstanding. The foregoing limitation shall not apply to (i) the incurrence by
the Company of Indebtedness represented by mortgage financings or purchase money
obligations, in each case incurred for the purpose of financing all or any part
of the purchase price or cost of construction or improvement of property used in
the business of the Company, or (ii) the incurrence by the Company of
Indebtedness represented by the Notes. For the purposes of this Section 5.11,
the term "Indebtedness" shall mean any indebtedness of the Company in respect of
borrowed money, whether or not contingent and whether or not evidenced by bonds,
notes, debentures or similar instruments.

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

quarter and the related consolidated statements of operations, shareholders'
equity and cash flows for such fiscal quarter and (ii) a report containing a
management's discussion and analysis of the financial condition and results of

                                       31
<PAGE>
          (a) the Company shall default in the payment when due of (i) any

     accordance with the provisions of Article XVI; or

          (b) failure on the part of the Company duly to observe or perform any
     other of the covenants on the part of the Company in the Notes or in this
     Indenture (other than default in performance of a covenant that is
     specifically dealt with elsewhere in this Section) including, without
     limitation, failure on the part of the Company to provide a written notice
     of a Repurchase Event in accordance with Section 16.2, and in any such case
     the continuance of such failure for a period of thirty (30) days after the
     date on which written notice of such failure, specifying such default and
     requiring the Company to remedy the same, and stating that such notice is a
     "Notice of Default" hereunder, shall have been given to the Company by the
     Trustee, or to the Company and a Responsible Officer of the Trustee by the
     holders of not less than 20% in aggregate principal amount of the Notes at
     the time outstanding determined in accordance with Section 9.4; or

          (c) failure on the part of the Company or any Significant Subsidiary
     to make any payment at maturity, including any applicable grace period, in
     respect of indebtedness of, or guaranteed or assumed by, the Company or any
     Significant Subsidiary, in a principal amount then outstanding in excess of
     Five Million United States Dollars ($5,000,000), and the continuance of
     such failure for a period of fifteen (15) days after there shall have been
     given, by registered or certified mail, to the Company by the Trustee
     (provided, however, that the Trustee will not be deemed to have knowledge
     of such nonpayment unless either (1) a Responsible Officer of the Trustee
     has actual knowledge of such nonpayment or (2) the Trustee has received
     written notice thereof from the Company, from any holder of the Notes, from
     the holder of any such indebtedness or from the trustee under the agreement
     or instrument relating to such indebtedness) or to the Company and a
     Responsible Officer of the Trustee by the holders of not less than 20% in
     aggregate principal amount of the Notes then outstanding, a written notice
     specifying such default and requiring the Company to cause such default to
     be cured or waived and stating that such notice is a "Notice of Default"
     hereunder; or

          (d) default on the part of the Company or any Significant Subsidiary
     with respect to any Indebtedness of, or guaranteed or assumed by, the
     Company or any Significant Subsidiary, which default results in the

     excess of Five Million United States Dollars ($5,000,000), and such
     indebtedness shall not have been discharged or such acceleration shall not
     have been rescinded or annulled for a period of fifteen (15) days after
     there shall have been given, by registered or certified mail, to the
     Company by the Trustee (provided, however, that the Trustee will not be
     deemed to have knowledge of such default unless either (1) a Responsible
     Officer of the Trustee has actual knowledge of such default or (2) the
     Trustee has received

                                       32
<PAGE>
     written notice thereof from the Company, from any holder of the Notes, from
     the holder of any such Indebtedness or from the trustee under the agreement
     or instrument relating to such Indebtedness) or to the Company and a
     Responsible Officer of the Trustee by the holders of not less than 20% in
     aggregate principal amount of the Notes then outstanding, a written notice
     specifying such default and requiring the Company to cause such
     indebtedness to be discharged or cause such default to be cured or waived
     or such acceleration to be rescinded or annulled and stating that such
     notice is a "Notice of Default" hereunder; or

          (e) the Company or any Significant Subsidiary shall commence a
     voluntary case or other proceeding seeking liquidation, reorganization or
     other relief with respect to itself or its debts under any bankruptcy,
     insolvency or other similar law now or hereafter in effect or seeking the
     appointment of a trustee, receiver, liquidator, custodian or other similar
     official of it or any substantial part of its property, or shall consent to
     any such relief or to the appointment of or taking possession by any such
     official in an involuntary case or other proceeding commenced against it,
     or shall make a general assignment for the benefit of creditors, or shall
     fail generally to pay its debts as they become due; or

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

     then, and in each and every such case (other than an Event of Default
     specified in Section 7.1(e) or (f) with respect to the Company), unless the
     principal of all of the Notes shall have already become due and payable,
     and unless the Event of Default shall have been waived in writing in
     accordance with the provisions of Section 7.7, either the Trustee or the
     holders of not less than 20% in aggregate principal amount of the Notes
     then outstanding hereunder determined in accordance with Section 9.4, by
     notice in writing to the Company (and to the Trustee if given by
     Noteholders), may declare the principal of and premium, if any, on all the
     Notes and the interest accrued thereon (including Liquidated Damages to the
     extent accrued and unpaid) to be due and payable immediately, and upon any
     such declaration the same shall become and shall be immediately due and
     payable, anything in this Indenture or in the Notes contained to the
     contrary notwithstanding. If an Event of Default specified in Section
     7.1(e) or (f) occurs and is continuing with respect to the Company, the
     principal of all the Notes and the interest accrued thereon (including
     Liquidated Damages to the extent accrued and unpaid) shall be immediately
     due and payable. In addition to the foregoing, upon an Event of Default and
     for so long as such Event of Default has not been cured or waived pursuant
     to Section 7.7, the rate of interest on the Notes shall be increased by
     five percent (5%) per annum (i.e., from 6% to 11% per annum) or, if less,
     increased to the maximum interest rate then permitted by applicable law.
     Any such interest which is not paid when due shall, to the maximum extent
     permitted by law, accrue interest until paid at the rate from time to time
     applicable to the interest on the Notes. Notwithstanding the foregoing if,
     at

                                       33
<PAGE>
     any time after the principal of the Notes shall have been so declared due
     and payable, and before any judgment or decree for the payment of the
     monies due shall have been obtained or entered as hereinafter provided, the
     Company shall pay or shall deposit with the Trustee a sum sufficient to pay
     all matured installments of interest upon all Notes and the principal of
     and premium, if any, on any and all Notes which shall have become due
     otherwise than by acceleration (with interest on overdue installments of
     interest (to the extent that payment of such interest is enforceable under
     applicable law) and on such principal and premium, if any, at the rate
     borne by the Notes, to the date of such payment or deposit) and amounts due
     to the Trustee pursuant to Section 8.6, and if any and all defaults under
     this Indenture, other than the nonpayment of principal of and premium, if
     any, and accrued interest on Notes which shall have become due by
     acceleration, shall have been cured or waived pursuant to Section 7.7, then
     and in every such case the holders of a majority in aggregate principal
     amount of the Notes then outstanding, by written notice to the Company and
     to the Trustee, may waive all defaults or Events of Default and rescind and
     annul such acceleration and its consequences; but no such waiver or
     rescission and annulment shall extend to or shall affect any subsequent
     default or Event of Default, or shall impair any right consequent thereon.

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

     Section 7.2 Payments of Notes on Default; Suit Therefor

     The Company covenants that (a) in case default shall be made in the payment
by the Company of any installment of interest upon any of the Notes as and when
the same shall become due and payable, and such default shall have continued for
a period of thirty (30) days, or (b) in case default shall be made in the
payment of the principal of or premium, if any, on any of the Notes as and when
the same shall have become due and payable, whether at maturity of the Notes or
in connection with any redemption or repurchase, by declaration under this
Indenture or otherwise, then, upon written demand of the Trustee, the Company
will pay to the Trustee, for the benefit of the holders of the Notes, the whole
amount that then shall have become due and payable on all such Notes for
principal and premium, if any, or interest, or both, as the case may be, with
interest upon the overdue principal and premium, if any, and (to the extent that
payment of such interest is enforceable under applicable law) upon the overdue
installments of interest at the rate borne by the Notes; and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including reasonable compensation to the Trustee, its
agents, attorneys and counsel, and any expenses or liabilities incurred by the
Trustee hereunder other than through its negligence or bad faith. Until such
demand by the Trustee, the Company may pay the principal of and premium, if any,
and interest on the Notes to the registered holders, whether or not the Notes
are overdue.

                                       34
<PAGE>
     In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any actions or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company and collect in the manner provided
by law out of the property of the Company wherever situated the monies adjudged
or decreed to be payable.

     In case there shall be pending proceedings for the bankruptcy or for the
reorganization of the Company under Title 11 of the United States Code, or any
other applicable law, or in case a receiver, assignee or trustee in bankruptcy
or reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of the Company or the property of the Company,
the Trustee, irrespective of whether the principal of the Notes shall then be
due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand pursuant to the
provisions of this Section 7.2, shall be entitled and empowered, by intervention
in such proceedings or otherwise, to file and prove a claim or claims for the
whole amount of principal, premium, if any, and interest (including Liquidated
Damages, if any) owing and unpaid in respect of the Notes, and, in case of any
judicial proceedings, to file such proofs of claim and other papers or documents
and to take such other actions as it may deem necessary or advisable in order to
have the claims of the Trustee and of the Noteholders allowed in such judicial
proceedings relative to the Company, its creditors, or its property, and to
collect and receive any monies or other property payable or deliverable on any
such claims, and to distribute the same after the deduction of any amounts due
the Trustee under Section 8.6; and any receiver, assignee or trustee in
bankruptcy or reorganization, liquidator, custodian or similar official is
hereby authorized by each of the Noteholders to make such payments to the
Trustee, and, in the event that the Trustee shall consent to the making of such
payments directly to the Noteholders, to pay to the Trustee any amount due it
for reasonable compensation, expenses, advances and disbursements, including
agents and counsel fees incurred by it up to the date of such distribution. To
the extent that such payment of reasonable compensation, expenses, advances and
disbursements out of the estate in any such proceedings shall be denied for any
reason, payment of the same shall be secured by a lien on, and shall be paid out
of, any and all distributions, dividends, monies, securities and other property
which the holders of the Notes may be entitled to receive in such proceedings,
whether in liquidation or under any plan of reorganization or arrangement or
otherwise.

     All rights of action and of asserting claims under this Indenture, or under
any of the Notes, may be enforced by the Trustee without the possession of any
of the Notes, or the production thereof on any trial or other proceeding
relative thereto, and any such suit or proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the holders of the Notes.

     In any proceedings brought by the Trustee (and in any proceedings involving
the interpretation of any provision of this Indenture to which the Trustee shall
be a party) the Trustee shall be held to represent all the holders of the Notes,
and it shall not be necessary to make any holders of the Notes parties to any
such proceedings.

     Section 7.3 Application of Monies and Property Collected by Trustee

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

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

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

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

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

     Section 7.4 Proceedings by Noteholder

     Subject to the last two paragraphs of this Section 7.4, no holder of any
Note shall have any right by virtue of or by availing of any provision of this
Indenture to institute any suit, action or proceeding in equity or at law upon
or under or with respect to this Indenture, or for the appointment of a
receiver, trustee, liquidator, custodian or other similar official, or for any
other remedy hereunder, unless such holder previously shall have given to the
Trustee written notice of an Event of Default and of the continuance thereof, as
hereinbefore provided, and unless also the holders of not less than 20% in
aggregate principal amount of the Notes then outstanding shall have made written
request upon the Trustee to institute such action, suit or proceeding in its own
name as Trustee hereunder and shall have offered to the Trustee such indemnity
as may be reasonably satisfactory to the Trustee against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee for sixty (60)
days after its receipt of such notice, request and offer of indemnity, shall
have neglected or refused to institute any such action, suit or proceeding and
no direction inconsistent with such written request shall have been given to the
Trustee pursuant to Section 7.7; it being understood and intended, and being
expressly covenanted by the taker and holder of every Note with every other
taker and holder and the Trustee, that no one or more holders of Notes shall

                                       36
<PAGE>
have any right in any manner whatever by virtue of or by availing of any
provision of this Indenture to affect, disturb or prejudice the rights of any
other holder of Notes, or to obtain or seek to obtain priority over or
preference to any other such holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all holders of Notes (except as otherwise provided herein).
For the protection and enforcement of this Section 7.4, each and every
Noteholder and the Trustee shall be entitled to such relief as can be given
either at law or in equity.

     Notwithstanding any other provision of this Indenture and any provision of
any Note, the right of any holder of any Note to receive payment of the
principal of and premium, if any, and interest (including Liquidated Damages to
the extent accrued but unpaid) on such Note, on or after the respective due
dates expressed in such Note, or to institute suit for the enforcement of any
such payment on or after such respective dates against the Company shall not be
impaired or affected without the consent of such holder.

     Anything in this Indenture or the Notes to the contrary notwithstanding,
the holder of any Note, without the consent of either the Trustee or the holder
of any other Note, in his own behalf and for his own benefit, may enforce, and
may institute and maintain any proceeding suitable to enforce, such holder's
rights of conversion as provided herein.

     Section 7.5 Proceedings by Trustee

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

     Section 7.6 Remedies Cumulative and Continuing

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

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

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

     Section 7.8 Notice of Defaults

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

     Section 7.9 Undertaking to Pay Costs

     All parties to this Indenture agree, and each holder of any Note by his
acceptance thereof shall be deemed to have agreed, that any court may, in its
discretion, require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant;
provided that the provisions of this Section 7.9 shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Noteholder, or group of
Noteholders, holding in the aggregate more than 10% in

                                       38
<PAGE>
principal amount of the Notes at the time outstanding determined in accordance
with Section 9.4, or to any suit instituted by any Noteholder for the
enforcement of the payment of the principal of or premium, if any, or interest
(including Liquidated Damages to the extent accrued but unpaid) on any Note
(including, but not limited to, the redemption price or Repurchase Price with
respect to the Notes being redeemed or repurchased as provided in this
Indenture) on or after the due date expressed in such Note or to any suit for
the enforcement of the right to convert any Note in accordance with the
provisions of Article XV.

     Section 7.10 Delay or Omission Not Waiver

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

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

     Section 8.1 Duties and Responsibilities of Trustee

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

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

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

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

               (2) in the absence of bad faith or willful misconduct on the part
          of the Trustee, the Trustee may conclusively rely, as to the truth of
          the statements and the correctness of the opinions expressed therein,
          upon any certificates or opinions

                                       39
<PAGE>
          furnished to the Trustee and conforming to the requirements of this
          Indenture; provided, however, in the case of any such certificates or
          opinions that by any provisions hereof are specifically required to be
          furnished to the Trustee, the Trustee shall be under a duty to examine
          the same to determine whether or not they conform to the requirements
          of this Indenture;

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

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

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

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

     Section 8.2 Reliance on Documents, Opinions, Etc.

     Except as otherwise provided in Section 8.1:

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

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

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

                                       40
<PAGE>
     (d) the Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request, order or direction of
any of the Noteholders pursuant to the provisions of this Indenture, unless such
Noteholders shall have offered to the Trustee security or indemnity reasonably
satisfactory to it against the costs, expenses and liabilities which may be
incurred therein or thereby;

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

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

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

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

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

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

                                       41
<PAGE>
In no event shall the Trustee be liable for any consequential loss or damage of
any kind whatsoever (including but not limited to lost profits), even if the
Trustee has been advised of the likelihood of such loss or damage and regardless
of the form of action.

     Section 8.3 No Responsibility for Recitals, Etc.

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

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

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

     Section 8.5 Monies to be Held in Trust

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

     Section 8.6 Compensation and Expenses of Trustee

     The Company covenants and agrees to pay to the Trustee from time to time,
and the Trustee shall be entitled to, such compensation as the Company and the
Trustee shall from time to time agree in writing for all services rendered by
the Trustee hereunder in any capacity (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust), and the Company will pay or reimburse the Trustee upon its request for
all reasonable expenses, disbursements and advances reasonably incurred or made
by the Trustee in accordance with any of the provisions of this Indenture
(including the reasonable compensation and the expenses and disbursements of its
agents and counsel and of all Persons not regularly in its employ) except any
such expense, disbursement or advance as may arise from its negligence, willful
misconduct or bad faith. The Company also covenants to indemnify the Trustee or
any predecessor Trustee in any capacity under this Indenture and its agents and
any authenticating agent for, and to hold them harmless against, any and all
loss, damages, claims, liability or expense, including taxes (other than those
based upon, measured by or determined by the income of the Trustee), incurred
without negligence, willful misconduct or bad faith on the part of the Trustee
or such agent or authenticating agent, as the case may be, and arising out of or
in connection with the acceptance or administration of this trust or in any
other capacity hereunder, including the costs and expenses of defending

                                       42
<PAGE>
themselves against any claim (whether asserted by the Company, a holder or any
other Person) of liability in the premises. The obligations of the Company under
this Section 8.6 to compensate or indemnify the Trustee and to pay or reimburse
the Trustee for expenses, disbursements and advances shall be secured by a lien
upon all property and funds held or collected by the Trustee as such, except
funds held in trust herewith for the benefit of the holders of particular Notes
prior to the date of the accrual of such unpaid compensation or indemnifiable
claim. The obligation of the Company under this Section 8.6 shall survive the
satisfaction and discharge of this Indenture and the resignation or removal of
the Trustee. The indemnification provided in this Section 8.6 shall extend to
the officers, directors, agents and employees of the Trustee.

     When the Trustee and its agents and any authenticating agent incur expenses
or render services after an Event of Default specified in Section 7.1(e) or (f)
occurs, the expenses and the compensation for the services are intended to
constitute expenses of administration under any bankruptcy, insolvency or
similar laws.

     Section 8.7 Officer's Certificate as Evidence

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

     Section 8.8 Conflicting Interests of Trustee

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

     Section 8.9 Eligibility of Trustee

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

                                       43
<PAGE>
     Section 8.10 Resignation or Removal of Trustee

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

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

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

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

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

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

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

                                       44
<PAGE>
expense of the Company, petition any court of competent jurisdiction for an
appointment of a successor trustee.

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

     (e) If an instrument of acceptance by a successor Trustee shall not have
been delivered to the Trustee within thirty (30) days after the giving of such
notice of removal, the Trustee being removed may petition, at the expense of the
Company, any court of competent jurisdiction for the appointment of a successor
trustee.

     Section 8.11 Acceptance by Successor Trustee

     Any successor trustee appointed as provided in Section 8.10 shall execute,
acknowledge and deliver to the Company and to its predecessor trustee an
instrument accepting such appointment hereunder, and thereupon the resignation
or removal of the predecessor trustee shall become effective and such successor
trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, duties and obligations of its predecessor hereunder,
with like effect as if originally named as trustee herein; but, nevertheless, on
the written request of the Company or of the successor trustee, the trustee
ceasing to act shall, upon payment of any amounts then due it pursuant to the
provisions of Section 8.6, execute and deliver an instrument transferring to
such successor trustee all the rights and powers of the trustee so ceasing to
act. Upon request of any such successor trustee, the Company shall execute any
and all instruments in writing for more fully and certainly vesting in and
confirming to such successor trustee all such rights and powers. Any trustee
ceasing to act shall, nevertheless, retain a lien upon all property and funds
held or collected by such trustee as such, except for funds held in trust for
the benefit of holders of particular Notes, to secure any amounts then due it
pursuant to the provisions of Section 8.6.

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

     Upon acceptance of appointment by a successor trustee as provided in this
Section 8.11, the Company shall send or cause to be sent notice of the
succession of such trustee hereunder to the holders of Notes at their addresses
as they shall appear on the Note Register. If the Company fails to send such
notice within ten (10) days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be sent at the expense
of the Company.

     Section 8.12 Succession by Merger, Etc.

     Any corporation or other entity into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation or other entity succeeding to all or substantially all
of the corporate trust business of the Trustee (including the trust created by
this Indenture), shall be the successor to the Trustee hereunder without the
execution or filing of any

                                       45
<PAGE>
paper or any further act on the part of any of the parties hereto, provided that
in the case of any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee such corporation shall be qualified
under the provisions of Section 8.8 and eligible under the provisions of Section
8.9.

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

     Section 8.13 Limitation on Rights of Trustee as Creditor

     If and when the Trustee shall be or become a creditor of the Company, the
Trustee shall be subject to the provisions of the Trust Indenture Act regarding
the collection of the claims against the Company.

                                   ARTICLE IX

                           CONCERNING THE NOTEHOLDERS

     Section 9.1 Action by Noteholders

     Whenever in this Indenture it is provided that the holders of a specified
percentage in aggregate principal amount of the Notes may take any action
(including the making of any demand or request, the giving of any notice,
consent or waiver or the taking of any other action), the fact that at the time
of taking any such action, the holders of such specified percentage have joined
therein may be evidenced (a) by any instrument or any number of instruments of
similar tenor executed by Noteholders in person or by agent or proxy appointed
in writing, or (b) by the record of the holders of Notes voting in favor thereof
at any meeting of Noteholders duly called and held in accordance with the
provisions of Article X, or (c) by a combination of such instrument or
instruments and any such record of such a meeting of Noteholders. Whenever the
Company or the Trustee solicits the taking of any action by the holders of the
Notes, the Company or the Trustee may fix in advance of such solicitation, a
date as the record date for determining holders entitled to take such action.
The record date shall be not more than fifteen (15) days prior to the date of
commencement of solicitation of such action.

                                       46
<PAGE>
     Section 9.2 Proof of Execution by Noteholders

     Subject to the provisions of Sections 8.1, 8.2 and 10.5, proof of the
execution of any instrument by a Noteholder or his agent or proxy shall be
sufficient if made in accordance with such reasonable rules and regulations as
may be prescribed by the Trustee or in such manner as shall be satisfactory to
the Trustee. The holding of Notes shall be proved by the Note Register or by a
certificate of the Note Registrar. The record of any Noteholders' meeting shall
be proved in the manner provided in Section 10.6.

     Section 9.3 Who Are Deemed Absolute Owners

     The Company, the Trustee, any authenticating agent, any paying agent, any
conversion agent and any Note Registrar may deem the Person in whose name such
Note shall be registered upon the Note Register to be, and may treat him as, the
absolute owner of such Note (whether or not such Note shall be overdue and
notwithstanding any notation of ownership or other writing thereon) for the
purpose of receiving payment of or on account of the principal of, premium, if
any, and interest (including Liquidated Damages to the extent accrued but
unpaid) on such Note, for conversion of such Note and for all other purposes;
and neither the Company nor the Trustee nor any authenticating agent nor any
paying agent nor any conversion agent nor any Note Registrar shall be affected
by any notice to the contrary. All such payments so made to any holder, or upon
his order, shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for monies payable upon any
such Note.

     Section 9.4 Company-Owned Notes Disregarded

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

     Section 9.5 Revocation of Consents; Future Holders Bound

     At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 9.1, of the taking of any action by the holders of the

appropriate agreements and stipulations which may be therein contained and to
accept the conveyance, transfer and assignment of any property thereunder;
provided, however, the Trustee shall not be obligated to (but may, in its
discretion) enter into any supplemental indenture that affects the Trustee's own

impair or change in any respect adverse to the holder of Notes the obligation of
the Company to repurchase any Note at the option of the holder upon the
happening of a Repurchase Event or any Repurchase Date, or impair or adversely
affect the right of any Noteholder to institute suit for the payment thereof, or

indenture affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amendment or supplemental indenture.

     It shall not be necessary for the consent of the Noteholders under this

supplemental indenture, but it shall be sufficient if such consent shall approve
the substance thereof.

of this Article XI shall comply with the Trust Indenture Act, as then in effect;

indenture or the Trustee to be qualified under the Trust Indenture Act prior to
the time such qualification is in fact required under the terms of the Trust
Indenture Act or the Indenture has been qualified under the Trust Indenture Act,

amendment or supplemental indenture that any such qualification is required
prior to the time such qualification is in fact required under the terms of the

Indenture Act. Upon the execution of any amendment or supplemental indenture

determine, new Notes so modified as to conform, in the opinion of the Trustee

than amounts paid or that remain payable with respect to such Notes pursuant to
the terms of this Indenture and such Notes).

Company for any payment which such holder may be entitled to collect unless an
applicable abandoned property law designates another Person.

     If (i) the Trustee or the paying agent is unable to apply any money in
accordance with Section 13.2 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such

the then outstanding Notes so request by written notice to the Trustee, the
Company's obligations under this Indenture and the Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Section 13.1 until such
time as the Trustee or the paying agent is permitted to apply all such money in
accordance with Section 13.2; provided, however, that if the Company makes any
payment of interest on or principal of any Note following the reinstatement of

the Notes or this Indenture by reason of his, her or its status as such partner,

accepting a Note waives and releases all such liability. Such waiver and release
are part of the consideration for the issuance of the Notes.

                                   ARTICLE XV

                               CONVERSION OF NOTES

     Section 15.1 Right to Convert

     Subject to and upon compliance with the provisions of this Indenture, the
holder of any Note shall have the right, at the holder's option, at any time
following the date of original issuance of the Notes and prior to the close of
business on October 15, 2025 (except that, with respect to any Note or portion
of a Note that shall be called for redemption or shall have been noticed for
automatic conversion, such right shall terminate, except as provided in Section
3.4, at the close of business on the last Business Day prior to the Redemption
Date or the date fixed for automatic conversion of such Note or portion of a
Note unless the Company shall default in payment due upon redemption thereof or
the delivery of shares on automatic conversion thereof), to convert the
principal amount of any such Note, or any portion of such principal amount which
is One Thousand United States Dollars ($1,000) or an integral multiple thereof,
into that number of fully paid and non-assessable

                                       57
<PAGE>
shares of Common Stock (as such shares shall then be constituted) obtained by
dividing the principal amount of the Note or portion thereof surrendered for
conversion by the Conversion Price in effect at such time, by surrender of the
Note so to be converted in whole or in part in the manner provided in Section
15.2. A holder of Notes is not entitled to any rights of a holder of Common
Stock until such holder has converted his Notes to Common Stock, and then only
to the extent such Notes are deemed to have been converted to Common Stock under
this Article XV. A Note with respect to which a holder has delivered a notice in
accordance with Section 16.2 regarding such holder's election to require the
Company to repurchase such holder's Notes may be converted in accordance with
this Article XV only if such holder withdraws such repurchase notice by
delivering a written notice of withdrawal to the Company prior to the close of
business on the last Business Day prior to the Repurchase Date.

     Section 15.2 Exercise of Conversion Privilege; Issuance of Common Stock on
Conversion; Payment of Cash in Lieu of Issuance of Common Stock

     In order to exercise the conversion privilege with respect to any
Definitive Note, the holder of such Definitive Note then registered on the books
of the Company shall (i) deliver a written notice, in the form of the conversion
notice attached hereto as Exhibit B, or a facsimile thereof (the "Conversion
Notice"), to the Trustee, the Company (with a copy to the Company's legal
counsel) and the transfer agent at Wells Fargo Shareowner Services, Compliance
Department, 161 North Concord Exchange, Saint Paul, Minnesota 55075, of such
holder's election to convert, which notice shall specify that all of such Note
shall be converted or the portion thereof to be converted (which shall be One
Thousand United States Dollars ($1,000) or an integral multiple thereof) and the
name or names (with address) in which the shares of Common Stock which shall be
issuable on such conversion shall be issued, (ii) if such Note or portion
thereof is surrendered for conversion during the period from the close of
business on the record date for any Interest Payment Date through the close of
business on the last Business Day prior to such Interest Payment Date, pay by
wire transfer of immediately available funds or other method acceptable to the
Company, an amount equal to the interest otherwise payable on such Interest
Payment Date on the principal amount being converted; provided, however, that no
such payment need be made if there shall exist at the time of conversion a
default in the payment of interest on the Notes (except that if a special record
date for payment of such defaulted interest has been set as provided in Section
2.3 and the Note or portion thereof is surrendered for conversion during the
period from the close of business on such special record date through the close
of business on the Business Day next preceding the special interest payment date
then the holder shall pay an amount equal to that portion, if any, of the
interest payable on such special interest payment date that does not relate to
past due interest), (iii) pay by wire transfer of immediately available funds or
other method acceptable to the Company the transfer taxes, if any, required
pursuant to Section 15.8, and (iv) surrender the Definitive Note to be converted
in whole or in part to a common carrier for overnight delivery to the Company as
soon as practicable following such date (or an indemnification undertaking or
other form of security reasonably satisfactory to the Company with respect to
the Definitive Note in the case of its loss, theft or destruction). Anything
herein to the contrary notwithstanding, in the case of Global Securities,
conversion notices may be delivered and a Participant's interest in a Global
Note may be surrendered for conversion in accordance with the Applicable
Procedures as in effect from time to time. Each Note surrendered for conversion
shall, unless the shares issuable on conversion are to be issued in the same
name as

                                       58
<PAGE>
the registration of such Note, be duly endorsed by, or be accompanied by
instruments of transfer (including a broker's letter regarding compliance with
the prospectus delivery requirement, if applicable) in form satisfactory to the
Company duly executed by, the holder or his duly authorized attorney. Except as
provided in the fifth paragraph of this Section 15.2 or as otherwise agreed by
the Company, a Conversion Notice shall be irrevocable.

     The Company shall use its best efforts to, within three (3) Business Days
after the Conversion Date (as defined below) with respect to any Note, subject
to compliance with any restrictions on transfer if shares issuable on conversion
are to be issued in a name other than that of the Noteholder (as if such
transfer were a transfer of the Note or Notes (or portion thereof) so converted)
(a)(i) in the case of shares of Common Stock issuable upon such conversion that
will not, following issuance, be Restricted Securities, at the holder's request,
credit such aggregate number of full shares of Common Stock to which the holder
shall be entitled to the holder's or its designee's balance account with The
Depository Trust Company through its Deposit Withdrawal Agent Commission system
or (ii) issue and deliver to the address as specified in the Conversion Notice,
a certificate, registered in the name of the holder or its designee, for the
number of full shares of Common Stock to which the holder shall be entitled upon
such conversion, and (b) deliver to such holder a check or cash in respect of
any fractional interest in respect of a share of Common Stock arising upon such
conversion, as provided in Section 15.4 (which payment, if any, shall be paid no
later than five (5) Business Days after the Conversion Date). In case any Note
of a denomination greater than One Thousand United States Dollars ($1,000) shall
be surrendered for partial conversion, the Company shall execute and the Trustee
shall authenticate and deliver to the holder of the Note so surrendered, without
charge to such holder, a new Note or Notes in authorized denominations in an
aggregate principal amount equal to the unconverted portion of the surrendered
Note.

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

     The conversion shall be deemed to have been effected as to any such Note
(or portion thereof) on the date on which the requirements set forth above in
this Section 15.2 have been satisfied as to such Note (or portion thereof) (such
date, the "Conversion Date"), and the Person in whose name any shares of Common
Stock shall be issuable upon such conversion shall be deemed to have become on
the Conversion Date the holder of record of the shares represented thereby;
provided, however, that any such surrender on any date when the stock transfer
books of the Company shall be closed shall constitute the Person in whose name
the certificates are to be issued as the record holder thereof for all purposes
on the next succeeding day on which such stock transfer books are open, and the
Conversion Date for purposes of determining the Company's compliance with its
share delivery obligations under this Section 15.2 shall be such later date, but
such conversion shall be at the Conversion Price in effect on the date upon
which such Note shall be surrendered. For purposes of determining satisfaction
of the requirement set forth above with respect to the Conversion Date for any
Note, any facsimile required to be sent shall be deemed to

                                       59
<PAGE>
have been sent on a given day if such facsimile was received before 1:00 p.m.,
Minneapolis time, on such date, to the number listed above (unless a different
number is specified in a notice filed with the Trustee and sent by the Trustee,
at the Company's expense, to each holder of the Notes at such holder's address
appearing in the Note Register, as provided for in Section 2.5 of this
Indenture) and a confirmation of transmission of such facsimile is obtained.

     The foregoing provisions of this Section 15.2 notwithstanding, if a Holder
elects to convert all or any portion of a Note into shares of Common Stock and
the Company does not have a sufficient number of authorized shares of Common
Stock to deliver upon conversion, the Company may choose to satisfy all or any
portion of its conversion obligation in cash. For purposes of the foregoing
sentence, the Company, when determining whether it has a sufficient number of
authorized shares of Common Stock to deliver upon conversion, may treat as
outstanding any shares reserved (as of the date of this Indenture) by the
Company's Board of Directors for a specific purpose including issuance under any
existing stock option or other equity plan of the Company or other obligation of
the Company to issue shares of Common Stock (including the obligation
represented by the Warrants issued pursuant to the Securities Purchase Agreement
to the initial purchasers of the beneficial interests in the Notes). In this
case, the Company will notify the converting holder through the Trustee of the
dollar amount to be satisfied in cash (which must be expressed as a fixed
percentage of the principal amount of Notes to be converted) at any time on or
before the date that is two Business Days following the Company's receipt of the
Conversion Notice (the "Cash Settlement Notice Period"). If the Company elects
to pay cash for any portion of the shares otherwise issuable to the holder, the
holder may revoke the Conversion Notice at any time during the two Business Day
period beginning on the day after the final day of the Cash Settlement Notice
Period (the "Conversion Revocation Period"). With respect to any conversion to
be settled all or in part in cash as provided in the foregoing sentence:

          (i) if the Company elects to satisfy its entire conversion obligation
     in cash, it shall pay an amount in cash equal to (1) the number of shares
     of Common Stock otherwise issuable upon such conversion multiplied by (2)
     the greater of (A) the Closing Price (as defined in Section 15.6(e)) on the
     Trading Day (as defined in Section 15.6(e)) prior to the Conversion Date,
     or (B) the average of the daily Closing Prices per share of Common Stock
     for the 20 consecutive Trading Days beginning on the Trading Day
     immediately following the final day of the Conversion Revocation Period
     (the "Cash Settlement Averaging Period"); and

          (ii) if the Company elects to satisfy a fixed percentage (other than
     100%) of the principal amount of Notes to be converted by payment in cash,
     it shall deliver to the holder (1) an amount in cash equal to (A) the
     number of shares of Common Stock otherwise issuable upon conversion of the
     relevant fixed percentage of the principal amount of the Notes being
     converted multiplied by (B) the greater of (a) the Closing Price on the
     Trading Day prior to the Conversion Date, or (b) the average of the daily
     Closing Prices per share of Common Stock for the Cash Settlement Averaging
     Period together with (2) that number of shares of Common Stock otherwise
     issuable on the conversion of the remaining principal amount of the Notes
     being converted.

                                       60
<PAGE>
     Nothing in this Section 15.2 shall affect the right of a holder in whose
name any Note is registered at the close of business on a record date to receive
the interest payable on such Note on the related Interest Payment Date in
accordance with the terms of this Indenture and the Note.

     Except as provided in this Section 15.2 or in Section 15.3, no adjustment
shall be made for interest accrued on any Note converted or for dividends on any
shares issued upon the conversion of such Note as provided in this Article.
Except where a Note (or portion thereof) is surrendered for conversion on or
after the day immediately following a record date or special record date and
prior to the related Interest Payment Date or special interest payment date, in
which case interest shall be paid as provided in Section 2.3 to the holder of
record at the close of business on such record date or special record date,
accrued and unpaid interest on a Note (or portion thereof) surrendered for
conversion will be deemed paid by delivery of the shares of Common Stock
issuable on conversion.

     Section 15.3 Company Right to Force Automatic Conversion

     The Company may, at its option, automatically convert all or a portion of
the Notes (an "Automatic Conversion") at any time prior to October 15, 2025 if
the Closing Price (as defined in Section 15.6(e)) per share of the Common Stock
has exceeded one hundred and fifty percent (150%) of the Conversion Price then
in effect for at least twenty (20) Trading Days within a period of thirty (30)
consecutive Trading Days ending within five (5) Trading Days of the date the
Automatic Conversion Notice (defined below) specifying the date (the "Automatic
Conversion Date") on which an Automatic Conversion will become effective is sent
to all holders of Notes, provided that either (x) a registration statement
covering the resale of the Conversion Shares is effective and available for use
from the date of the Automatic Conversion Notice (as defined below) through and
including the earlier of 30 days after the Automatic Conversion Date or the last
date on which the registration statement is required to be kept effective under
the terms of the Registration Rights Agreement, or (y) the Conversion Shares
issuable upon the Automatic Conversion may be sold pursuant to Rule 144(k) under
the Securities Act (assuming, for purposes of such determination, that no
recipient of Conversion Shares is an "affiliate" of the Company within the
meaning of such Rule and that all recipients of Conversion Shares have held the
Notes since the date of their original issuance). The Company may only elect an
Automatic Conversion with respect to all or any part of the Notes if it has, as
of the date of the Automatic Conversion Notice required by the following
paragraph, sufficient shares of Common Stock authorized and available for
issuance on conversion of the Notes (or parts thereof) so called for Automatic
Conversion. If the Automatic Conversion Date is prior to October 15, 2008, the
Company shall make an additional payment to each holder of Notes with respect to
the Notes converted (or portion thereof), in an amount equal to $181.33 per each
One Thousand United States Dollars ($1,000) principal amount of the holder's
Notes (or portion thereof) (the "Company Conversion Provisional Payment"), less
the amount of any interest actually paid on the holder's Notes (or portion
thereof) prior to the Automatic Conversion Date (and, if the relevant Notes are
converted after a record date and prior to the related Interest Payment Date,
less interest payable on such Notes (or portion thereof) on such Interest
Payment Date, which interest shall be paid to the record holder at the close of
business on the relevant record date as provided in Section 2.3). Except as
provided in the immediately preceding sentence, if the Automatic Conversion Date
with respect to any Notes (or portions thereof) subject to an Automatic
Conversion occurs following a record date and prior to the related Interest
Payment Date, then unless the Company defaults in its

                                       61
<PAGE>
obligation to deliver the shares of Common Stock issuable on such Automatic
Conversion. the Company shall not be obligated to pay any interest on such
Interest Payment Date, either to the holder of such Notes (or portions thereof)
at the close of business on the relevant record date or to the holder of such
Notes (or portions thereof) to whom the Company issues the shares of Common
Stock issuable on the Automatic Conversion.

     If the Company elects to convert all or a portion of the Notes pursuant to
this Section 15.3, the Company, or at its request (which must be received by the
Trustee at least five (5) Business Days prior to the date the Trustee is
requested to give notice as described below unless a shorter period is agreed to
by the Trustee), the Trustee in the name of and at the expense of the Company,
shall send or cause to be sent a notice (the "Automatic Conversion Notice") of
the Automatic Conversion not more than thirty (30) days but not less than five
(5) days before the Automatic Conversion Date to such holders at their last
addresses as they shall appear upon the Notes Register. Such notice shall be
irrevocable. Any notice that is sent in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the registered
holder receives the notice. In any case, failure to duly give such notice to the
holder of any Notes designated for Automatic Conversion in whole or in part, or
any defect in the notice, shall not affect the validity of the proceedings for
the Automatic Conversion of any other Notes.

     Each Automatic Conversion Notice shall state:

          (a) the Automatic Conversion Date,

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

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

          (d) the Conversion Price then in effect,

          (e) whether or not Additional Shares will be issued pursuant to
     Section 15.13 and, if so, the method for calculating the number of
     Additional Shares to be issued, and

          (f) the amount of the Company Conversions Provisional Payment, if any.

     In case the Notes are to be converted in part only, the Automatic
Conversion Notice shall state the portion of the principal amount thereof to be
converted and shall state that on and after the Automatic Conversion Date, upon
surrender of such Note, a new Note or Notes in principal amount equal to the
unconverted portion thereof will be issued.

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

     In the event of an Automatic Conversion, the Company shall (a) issue and
deliver a certificate or certificates for the number of full shares of Common
Stock issuable upon conversion of the Notes or, (b) in the case of shares of
Common Stock issuable upon such conversion that will not, following such
issuance, be Restricted Securities, at the holder's request, credit such
aggregate

                                       62
<PAGE>
number of shares of Common Stock to which the holder shall be entitled to the
holder's balance account with the Depositary through its Deposit Withdrawal
Agent Commission system, in either case along with (i) any cash in respect of
any fractional shares of Common Stock otherwise issuable upon conversion (as
provided in Section 15.4), and (ii) the Company Conversion Provisional Payment,
if any, for payment to the holder as promptly after the Automatic Conversion
Date as practicable in accordance with the provisions of this Section 15.3.

     All Notes subject to the Automatic Conversion shall be delivered to the
Company to be canceled. Failure to deliver such Notes shall not affect their
automatic cancellation.

     Section 15.4 Cash Payments in Lieu of Fractional Shares

     No fractional shares of Common Stock or scrip representing fractional
shares shall be issued upon conversion of Notes. If more than one Note shall be
surrendered for conversion at one time by the same holder, the number of full
shares which shall be issuable upon conversion thereof shall be computed on the
basis of the aggregate principal amount of the Notes (or specified portions
thereof to the extent permitted hereby) so surrendered for conversion. If any
fractional share of stock otherwise would be issuable upon the conversion of any
Note or Notes, the Company shall calculate and pay a cash adjustment in lieu of
such fractional share at the current market value thereof to the holder of
Notes. For purposes of this Section 15.4, the current market value of a share of
Common Stock shall be the Closing Price (determined as provided in Section
15.6(e)) on the Trading Day immediately preceding the day on which the relevant
Notes (or specified portions thereof) are deemed to have been converted.

     Section 15.5 Conversion Price

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

     Section 15.6 Adjustment of Conversion Price

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

     (a) In case the Company shall hereafter pay a dividend or make a
distribution to all holders of the outstanding Common Stock in shares of Common
Stock, the Conversion Price in effect at the opening of business on the Business
Day following the date fixed for the determination of shareholders entitled to
receive such dividend or other distribution shall be reduced by multiplying such
Conversion Price by a fraction of which (i) the numerator shall be the number of
shares of Common Stock outstanding at the close of business on the Record Date
(as defined in Section 15.6(e)) fixed for such determination and (ii) the
denominator shall be the sum of such number of shares and the total number of
shares constituting such dividend or other distribution, such reduction in the
Conversion Price to become effective immediately after the opening of business
on the Business Day following the Record Date. If any dividend or distribution
of the type described in this Section 15.6(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.

                                       63
<PAGE>
     (b) In case the outstanding shares of Common Stock shall be subdivided into
a greater number of shares of Common Stock, the Conversion Price in effect at
the opening of business on the Business Day following the day upon which such
subdivision becomes effective shall be proportionately reduced, and conversely,
in case outstanding shares of Common Stock shall be combined into a smaller
number of shares of Common Stock, the Conversion Price in effect at the opening
of business on the Business 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 Business Day following the day upon which such subdivision or
combination becomes effective.

     (c) In case 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 into shares of Common Stock at a price per
share less than the Current Market Price (as defined in Section 15.6(e)) (other
than rights or warrants subject to the third paragraph of Section 15.6(d)) on
the Record Date fixed for the determination of shareholders 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 Business Day after such Record Date by a
fraction of which (i) the numerator shall be the sum of the number of shares of
Common Stock outstanding at the close of business on the Record Date plus the
number of shares that the aggregate offering price of the total number of shares
so offered for subscription or purchase would purchase at such Current Market
Price, and of which (ii) the denominator shall be the sum of the number of
shares of Common Stock outstanding at the close of business on the Record Date
plus the total number of additional shares of Common Stock so offered for
subscription or purchase. Such adjustment shall become effective immediately
after the opening of business on the Business Day following the Record Date
fixed for determination of shareholders entitled to receive such rights or
warrants. To the extent that shares of Common Stock are not delivered pursuant
to such rights or warrants, upon the expiration or termination of such rights or
warrants the Conversion Price shall be readjusted to the Conversion Price that
would then be in effect had the adjustments made upon the issuance of such
rights or warrants been made on the basis of delivery of only the number of
shares of Common Stock actually delivered. In the event that such rights or
warrants are not so issued, the Conversion Price shall again be adjusted to be
the Conversion Price that would then be in effect if the Record Date for the
determination of shareholders entitled to receive such rights or warrants had
not been fixed. In determining whether any rights or warrants entitle the
holders to subscribe for or purchase shares of Common Stock at less than such
Current Market Price, and in determining the aggregate offering price of such
shares of Common Stock, there shall be taken into account any consideration
received for such rights or warrants, the value of such consideration, if other
than cash, to be determined in good faith by the Board of Directors.

     (d) In case the Company shall, by dividend or otherwise, distribute to all
or substantially all holders of its Common Stock shares of any class of capital
stock of the Company (other than any dividends or distributions to which Section
15.6(a) applies) or evidences of its indebtedness or other assets (including
securities, but excluding (1) any rights or warrants referred to in Section
15.6(c) and (2) dividends and distributions paid exclusively in cash, which are
subject to the last paragraph of this Section 15.6(d), (the foregoing
hereinafter in this Section 15.6(d) called the "Additional Securities")), unless
the Company elects to reserve such Additional Securities for distribution to the

                                       64
<PAGE>
Noteholders upon conversion of the Notes so that any such holder converting
Notes will receive upon such conversion, in addition to the shares of Common
Stock to which such holder is entitled, the amount and kind of such Additional
Securities which such holder would have received if such holder had converted
its Notes into Common Stock immediately prior to the Record Date (as defined in
Section 15.6(e)) for such distribution of the Additional 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 with respect to
such distribution by a fraction of which (i) the numerator shall be the Current
Market Price (determined as provided in Section 15.6(e)) 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 Board Resolution) on such
date of the portion of the Additional Securities so distributed applicable to
one share of Common Stock (determined on the basis of the number of shares of
Common Stock outstanding on the Record Date) and (ii) the denominator shall be
such Current Market Price, such reduction to become effective immediately prior
to the opening of business on the Business Day following the Record Date;
provided, however, that in the event the then fair market value (as so
determined) of the portion of the Additional Securities so distributed
applicable to one share of Common Stock is equal to or greater than the Current
Market Price on the Record Date, in lieu of the foregoing adjustment, adequate
provision shall be made so that each Noteholder shall have the right to receive
upon conversion of a Note (or any portion thereof) the amount of Common Stock,
other capital stock, evidences of indebtedness and other assets that such holder
would have received had such holder converted such Note (or portion thereof)
immediately prior to such Record Date and immediately thereafter received such
Additional Securities. In the event that such dividend or distribution is not so
paid or made, the Conversion Price shall again be adjusted to be the Conversion
Price which would then be in effect if such dividend or distribution had not
been declared. If the Board of Directors determines the fair market value of any
distribution for purposes of this Section 15.6(d) by reference to the actual or
when issued trading market for any securities comprising all or part of such
distribution, it must in doing so consider the prices in such market over the
same period (the "Reference Period") used in computing the Current Market Price
pursuant to Section 15.6(e) to the extent possible, unless the Board of
Directors in a Board Resolution determines in good faith that determining the
fair market value during the Reference Period would not be in the best interest
of the Noteholders.

     In the event that the Company implements a new shareholder rights plan,
such rights plan shall provide that upon conversion of the Notes the holders
will receive, in addition to the Common Stock issuable upon such conversion, the
rights issued under such rights plan as if the holders had converted the Notes
prior to implementing the rights plan and notwithstanding the occurrence of an
event causing such rights to separate from the Common Stock at or prior to the
time of conversion. Any distribution of rights or warrants pursuant to a
shareholder rights plan complying with the requirements set forth in the
immediately preceding sentence of this paragraph shall not constitute a
distribution of rights or warrants for the purposes of Section 15.6(c) or this
Section 15.6(d).

     Rights or warrants distributed by the Company to all holders of Common
Stock entitling the holders thereof to subscribe for or purchase shares of the
Company's capital stock (either initially or under certain circumstances), which
rights or warrants, until the occurrence of a specified event or events
("Trigger Event"): (i) are deemed to be transferred with such shares of Common
Stock;

                                       65
<PAGE>
(ii) are not exercisable; and (iii) are also issued in respect of future
issuances of Common Stock, shall be deemed not to have been distributed for
purposes of this Section 15.6(d) (and no adjustment to the Conversion Price
under this Section 15.6(d) will be required) until the occurrence of the
earliest Trigger Event. If such right or warrant is subject to subsequent
events, upon the occurrence of which such right or warrant shall become
exercisable to purchase different securities, evidences of indebtedness or other
assets or entitle the holder to purchase a different number or amount of the
foregoing or to purchase any of the foregoing at a different purchase price,
then the occurrence of each such event shall be deemed to be the date of
issuance and record date with respect to a new right or warrant (and a
termination or expiration of the existing right or warrant without exercise by
the holder thereof). In addition, in the event of any distribution (or deemed
distribution) of rights or warrants, or any Trigger Event or other event (of the
type described in the preceding sentence) with respect thereto, that resulted in
an adjustment to the Conversion Price under this Section 15.6(d), (1) in the
case of any such rights or warrants that shall all have been redeemed or
repurchased without exercise by any holders thereof, the Conversion Price shall
be readjusted upon such final redemption or repurchase to give effect to such
distribution or Trigger Event, as the case may be, as though it were a cash
distribution, equal to the per share redemption or repurchase price received by
a holder of Common Stock with respect to such rights or warrants (assuming such
holder had retained such rights or warrants), made to all holders of Common
Stock as of the date of such redemption or repurchase, and (2) in the case of
such rights or warrants all of which shall have expired or been terminated
without exercise, the Conversion Price shall be readjusted as if such rights and
warrants had never been issued.

     For purposes of this Section 15.6(d) and Sections 15.6(a) and (c), any
dividend or distribution to which this Section 15.6(d) is applicable that also
includes shares of Common Stock, or rights or warrants to subscribe for or
purchase shares of Common Stock to which Section 15.6(a) or 15.6(c) applies (or
both), shall be deemed to be (1) a dividend or distribution of the evidences of
indebtedness, assets, shares of capital stock, rights or warrants to which this
Section 15.6(d) applies (and any Conversion Price reduction required by this
Section 15.6(d) with respect to such dividend or distribution shall first be
made) immediately followed by (2) a dividend or distribution of the shares of
Common Stock or rights or warrants to which Sections 15.6(a) and (c) apply (and
any further Conversion Price reduction required by Sections 15.6(a) and (c) with
respect to such dividend or distribution shall then be made), except (A) the
Record Date of such dividend or distribution shall be substituted as "the date
fixed for the determination of shareholders entitled to receive such dividend or
other distribution", "Record Date fixed for such determination" and "Record
Date" within the meaning of Section 15.6(a) and as "the date fixed for the
determination of shareholders entitled to receive such rights or warrants", "the
Record Date fixed for the determination of the shareholders entitled to receive
such rights or warrants" and "such Record Date" within the meaning of Section
15.6(c) and (B) any shares of Common Stock included in such dividend or
distribution shall not be deemed "outstanding at the close of business on the
date fixed for such determination" within the meaning of Section 15.6(a).

     In case the Company shall, by dividend or otherwise, distribute to all or
substantially all holders of its Common Stock cash (excluding any cash that is
distributed upon a merger or consolidation to which Section 15.7 applies or as
part of a distribution referred to elsewhere in this Section 15.6(d)), then
immediately after the close of business on the Record Date for the

                                       66
<PAGE>
distribution, the Conversion Price shall be reduced so that the same shall equal
the price determined by multiplying the Conversion Price in effect immediately
prior to the close of business on such Record Date by a fraction (i) the
numerator of which shall be equal to the Current Market Price on the Record Date
less the portion of the cash so distributed applicable to one (1) share of
Common Stock and (ii) the denominator of which shall be equal to the Current
Market Price on such date; provided, however, that in the event the portion of
the cash so distributed applicable to one (1) share of Common Stock is equal to
or greater than the Current Market Price of the Common Stock on the Record Date,
in lieu of the foregoing adjustment, adequate provision shall be made so that
each holder shall have the right to receive upon conversion of a Note (or any
portion thereof) the amount of Common Stock and cash such holder would have
received had such holder converted such Note (or portion thereof) immediately
prior to such Record Date and immediately thereafter received such cash
distribution. In the event that such dividend or distribution is not so paid or
made, the Conversion Price shall again be adjusted to be the Conversion Price
that would then be in effect if such dividend or distribution had not been
declared.

     (e) For purposes of this Section 15.6, the following terms shall have the
meaning indicated:

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

          (2) "Current Market Price" shall mean the average of the daily Closing
     Prices per share of Common Stock for the ten (10) consecutive Trading Days
     immediately prior to the date in question; provided, however, that (1) if
     the "ex" date (as hereinafter defined) for any event (other than the
     issuance or distribution requiring such computation) that requires an
     adjustment to the Conversion Price pursuant to Section 15.6(a), (b), (c) or
     (d) occurs during such ten (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 15.6(a), (b), (c) or (d) 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

                                       67
<PAGE>
     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 in good faith by the Company's
     Board of Directors in a manner consistent with any determination of such
     value for purposes of Section 15.6(d), whose determination shall be
     conclusive and described in a Board Resolution) of the evidences of
     indebtedness, shares of capital stock or assets being distributed
     applicable to one share of Common Stock as of the close of business on the
     day before such "ex" date. For purposes of this paragraph, the term "ex"
     date, (1) when used with respect to any issuance or distribution, means the
     first date on which the Common Stock trades regular way on the relevant
     exchange or in the relevant market from which the Closing Price was
     obtained without the right to receive such issuance or distribution and (2)
     when used with respect to any subdivision or combination of shares of
     Common Stock, means the first date on which the Common Stock trades regular
     way on such exchange or in such market after the time at which such
     subdivision or combination becomes effective. Notwithstanding the
     foregoing, whenever successive adjustments to the Conversion Price are
     called for pursuant to this Section 15.6, such adjustments shall be made to
     the Current Market Price as may be necessary or appropriate to effectuate
     the intent of this Section 15.6 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 shareholders 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
     security exchange, a day on which the New York Stock Exchange or such other
     national security exchange, as applicable, is open for business or (y) if
     the applicable security is quoted on the Nasdaq National Market, a day on
     which trades may be made thereon or (z) if the applicable security is not
     so listed, admitted for trading or quoted, a Business Day.

     (f) The Company may make such reductions in the Conversion Price, in
addition to those required by Sections 15.6(a), (b), (c) or (d), 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

                                       68
<PAGE>
resulting from any dividend or distribution of stock (or rights to acquire
stock) or from any event treated as such for income tax purposes.

     (g) To the extent permitted by applicable law, the Company from time to
time may reduce the Conversion Price by any amount for any period of time if the
period is at least twenty (20) days, the reduction is irrevocable during the
period and the Board of Directors shall have made a determination that such
reduction would be in the best interests of the Company, which determination
shall be conclusive and described in a Board Resolution. Whenever the Conversion
Price is reduced pursuant to the preceding sentence, the Company shall send to
the holder of each Note at his last address appearing on the Note Register
provided for in Section 2.5(a) a notice of the reduction at least five (5) days
prior to the date the reduced Conversion Price takes effect, and such notice
shall state the reduced Conversion Price and the period during which it will be
in effect. A reduction of the Conversion Price pursuant to this Section 15.6(g)
does not change or adjust the Conversion Price otherwise in effect for purposes
of the other provisions of this Section 15.6.

     (h) No adjustment in the Conversion Price shall be required under this
Section 15.6 unless such adjustment would require an increase or decrease of at
least one percent (1%) in such price; provided, however, that any adjustments
which by reason of this Section 15.6 (h) are not required to be made shall be
carried forward and taken into account in any subsequent adjustment. All
calculations under this Article XV shall be made by the Company and shall be
made to the nearest cent or to the nearest one hundredth of a share, as the case
may be. No adjustment need be made for a change in the par value or no par value
of the Common Stock. Except as otherwise described in this Section 15.6, no
adjustment in the Conversion Price shall be required for the issuance of shares
of Common Stock or the right to purchase shares of Common Stock. To the extent
that the Notes become convertible into cash, no adjustment need be made
thereafter as to the cash and interest will not accrue on that cash.

     (i) Subject to Section 15.6(g), whenever the Conversion Price is adjusted
as provided in this Section 15.6, the Company shall promptly file with the
Trustee and any conversion agent other than the Trustee an Officer's Certificate
setting forth the Conversion Price after such adjustment and setting forth a
brief statement of the facts requiring such adjustment. Promptly after delivery
of such certificate, the Company shall prepare a notice of such adjustment of
the Conversion Price setting forth the adjusted Conversion Price and the date on
which each adjustment becomes effective and shall send such notice of such
adjustment of the Conversion Price to the holder of each Note at his last
address appearing on the Note Register provided for in Section 2.5(a), within
twenty (20) days of the effective date of such adjustment. Failure to deliver
such notice shall not effect the legality or validity of any such adjustment.

     (j) In any case in which this Section 15.6 provides that an adjustment
shall become effective immediately after a Record Date for an event, the Company
may defer until the occurrence of such event (i) issuing to the holder of any
Note (or portion thereof) converted after such Record Date and before the
occurrence of such event the additional shares of Common Stock issuable upon
such conversion by reason of the adjustment required by such event over and
above the Common Stock issuable upon such conversion before giving effect to
such adjustment and (ii) paying to such holder any amount in cash in lieu of any
fraction pursuant to Section 15.4.

                                       69
<PAGE>
     (k) For purposes of this Section 15.6, the number of shares of Common Stock
at any time outstanding shall not include shares held in the treasury of the
Company but shall include shares issuable in respect of scrip certificates
issued in lieu of fractions of shares of Common Stock. The Company will not pay
any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.

     Section 15.7 Effect of Reclassification, Consolidation, Merger or Sale

     Subject to the provisions of Article XVI, if any of the following events
occurs, namely (i) any reclassification or change of the outstanding shares of
Common Stock (other than a change in par value, or from par value to no par
value, or from no par value to par value, or as a result of a subdivision or
combination), (ii) any consolidation, merger or combination of the Company with
another Person as a result of which holders of Common Stock shall be entitled to
receive stock, securities or other property or assets (including cash) with
respect to or in exchange for such Common Stock (other than as a result of a
change in name, a change in par value or a change in the jurisdiction of
incorporation), (iii) any statutory exchange as a result of which holders of
Common Stock generally shall be entitled to receive stock, securities or other
property or assets (including cash) with respect to or in exchange for such
Common Stock (such transaction, a "Statutory Exchange"), or (iv) any sale or
conveyance of the properties and assets of the Company as, or substantially as,
an entirety to any other Person as a result of which holders of Common Stock
shall be entitled to receive stock, securities or other property or assets
(including cash) with respect to or in exchange for such Common Stock, then the
Company or the successor or purchasing Person, as the case may be, shall execute
with the Trustee a supplemental indenture (which shall comply with the Trust
Indenture Act as in force at the date of execution of such supplemental
indenture if such supplemental indenture is then required to so comply)
providing that such Note shall be convertible into the kind and amount of shares
of stock and other securities or property or assets (including cash) receivable
upon such reclassification, change, consolidation, merger, combination,
Statutory Exchange, sale or conveyance by a holder of a number of shares of
Common Stock issuable upon conversion of such Notes (assuming, for such
purposes, a sufficient number of authorized shares of Common Stock available to
convert all such Notes) immediately prior to such reclassification, change,
consolidation, merger, combination, Statutory Exchange, sale or conveyance. In
the event holders of Common Stock have the opportunity to elect the form of
consideration to be received in such reclassification, change, consolidation,
merger, combination, Statutory Exchange, sale or conveyance, the Company shall
make adequate provision whereby the holders of the Notes shall have a reasonable
opportunity to determine the form of consideration into which all of the Notes
shall be convertible from and after the effective date of such reclassification,
change, consolidation, merger, combination, Statutory Exchange, sale or
conveyance. Such determination shall be (i) based on the weighted average of
elections made by holders of the Notes who participate in such determination,
(ii) subject to any limitations to which all of the holders of the Common Stock
are subject, such as pro-rata reductions applicable to any portion of the
consideration payable in such reclassification, change, consolidation, merger,
combination, Statutory Exchange, sale or conveyance, and (iii) conducted in such
a manner as to be completed by the date which is the earliest of (a) the
deadline for elections to be made by stockholders of the Company, and (b) two
Trading Days prior to the anticipated effective date of the reclassification,
change, consolidation, merger, combination, Statutory Exchange, sale or
conveyance. The Company shall provide notice of the

                                       70
<PAGE>
opportunity to determine the form of such consideration, as well as notice of
the determination made by holders of the Notes (and the weighted average of
elections), by issuing a press release and providing a copy of such notice to
the Trustee. In the event the effective date of the reclassification, change,
consolidation, merger, combination, Statutory Exchange, sale or conveyance is
delayed beyond the initially anticipated effective date, holders of the Notes
shall be given the opportunity to make subsequent similar determinations in
regard to such delayed effective date. Such supplemental indenture shall provide
for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article XV. If, in the case of any such
reclassification, change, consolidation, merger, combination, Statutory
Exchange, sale or conveyance, the stock or other securities and assets
receivable thereupon by a holder of shares of Common Stock include shares of
stock or other securities and assets of a Person other than the successor or
purchasing Person, as the case may be, in such reclassification, change,
consolidation, merger, combination, Statutory Exchange, sale or conveyance, then
such supplemental indenture shall also be executed by such other Person and
shall contain such additional provisions to protect the interests of the holders
of the Notes as the Company's Board of Directors shall reasonably consider
necessary by reason of the foregoing, including to the extent practicable the
provisions providing for the repurchase rights set forth in Article XVI herein.

     The Company shall cause notice of the execution of such supplemental
indenture to be sent to each holder of Notes, at his address appearing on the
Note Register provided for in Section 2.5(a) of this Indenture, within twenty
(20) days after execution thereof. Failure to deliver such notice shall not
affect the legality or validity of such supplemental indenture.

     The above provisions of this Section 15.7 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

     If this Section 15.7 applies to any event or occurrence, Section 15.6 shall
not apply.

     Section 15.8 Taxes on Shares Issued

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

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

     The Company shall provide, free from preemptive rights, out of its
authorized but unissued shares, reserved for the purpose of issuance, no less
than one hundred five percent (105%) of the number of shares of Common Stock
needed to provide for the issuance of Common Stock upon conversion of all of the
Notes without regard to any limitations on conversions or exercise (but not
including any Additional Shares); provided that until such date, if any, after
the date hereof as the shareholders of the Company approve an increase in the
authorized capital stock of the Company

                                       71
<PAGE>
such that there are sufficient shares therefor (the "Approval Date"), the number
of shares required to be reserved shall be reduced to the total number of the
Company's authorized but unissued shares that, as of the date hereof, are
available for issuance and have not been reserved by the Company's Board of
Directors for a specific purpose as of the date hereof including issuance under
any existing stock option or other equity plan of the Company or other
obligation of the Company to issue shares of Common Stock (including the
obligation represented by the Warrants issued pursuant to the Securities
Purchase Agreement to the initial purchasers of the beneficial interests in the
Notes).

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

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

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

     The Company shall use commercially reasonable efforts to promptly secure
the listing of the shares of Common Stock issuable upon conversion of the Notes
upon each national securities exchange and automated quotation system, if any,
upon which shares of Common Stock are then listed (subject to official notice of
issuance upon conversion of such Notes) and shall use commercially reasonable
efforts to maintain, so long as any other shares of Common Stock shall be so
listed, such listing of all shares of Common Stock from time to time issuable
upon the conversion of all then outstanding Notes; and the Company shall use
commercially reasonable efforts to list on each national securities exchange or
automated quotation system, as the case may be, and shall maintain such listing
of, any other shares of capital stock of the Company issuable upon conversion of
the Notes if and so long as any shares of the same class shall be listed on such
national securities

                                       72
<PAGE>
exchange or automated quotation system. The Company shall pay all fees and
expenses in connection with satisfying its obligations under this Section 15.9.

     Section 15.10 Responsibility of Trustee

     The Trustee and any other conversion agent shall not at any time be under
any duty or responsibility to any holder of Notes to determine whether any facts
exist which may require any adjustment of the Conversion Price, or with respect
to the nature or extent or calculation of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same. The Trustee and any other
conversion agent shall not be accountable with respect to the validity or value
(or the kind or amount) of any shares of Common Stock, or of any securities or
other property, which may at any time be issued or delivered upon the conversion
of any Note; and the Trustee and any other conversion agent make no
representations with respect thereto. Neither the Trustee nor any conversion
agent shall be responsible for any failure of the Company to issue, transfer or
deliver any shares of Common Stock or stock certificates or other securities or
other property or cash upon the surrender of any Note for the purpose of
conversion or to comply with any of the duties, responsibilities or covenants of
the Company contained in this Article XV. Without limiting the generality of the
foregoing, neither the Trustee nor any conversion agent shall be under any
responsibility to determine whether a supplemental indenture need be entered
into under Section 15.7 or the correctness of any provisions contained in any
supplemental indenture entered into pursuant to such section relating either to
the kind or amount of shares of stock or securities or other property (including
cash) receivable by Noteholders upon the conversion of their Notes after any
event referred to in such Section 15.7 or to any adjustment to be made with
respect thereto, but, subject to the provisions of Section 8.1, may accept as
conclusive evidence of the correctness of any such provisions, and shall be
protected in relying upon, the Officer's Certificate (which the Company shall be
obligated to file with the Trustee prior to the execution of any such
supplemental indenture) with respect thereto.

     Section 15.11 Notice to Holders Prior to Certain Actions

     In case:

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

          (b) the Company shall authorize the granting to the holders of its
     Common Stock of rights or warrants to subscribe for or purchase any share
     of any class or any other rights or warrants (other than rights or warrants
     described in the third paragraph of Section 15.6(d)); or

          (c) of any reclassification of the Common Stock of the Company (other
     than a subdivision or combination of its outstanding Common Stock, or a
     change in par value, or from par value to no par value, or from no par
     value to par value), or of any consolidation or merger to which the Company
     is a party and for which approval of any shareholders of the Company is
     required (other than a merger that only serves to change the Company's name
     or

                                       73
<PAGE>
     jurisdiction of incorporation), or of the sale or transfer of all or
     substantially all of the assets of the Company; or

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

the Company shall cause to be filed with the Trustee and to be sent to each
holder of Notes at his address appearing on the Note Register provided for in
Section 2.5(a) of this Indenture, as promptly as possible but in any event at
least fifteen (15) days prior to the applicable date hereinafter specified, a
notice stating (x) the date on which a record is to be taken for the purpose of
such dividend, distribution or granting of 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 or warrants 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, grant, reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.

     Section 15.12 Holder Not Deemed a Shareholder

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

     Section 15.13 Adjustment to Conversion Price Following Certain Changes of
Control

     In case (a) a Change of Control (as defined in Section 16.3) occurs as
defined in clause (iii) of the definition thereof (disregarding, for purposes of
this Section 15.13, the proviso at the end of such definition), (b) 10% or more
of the value of the consideration received by holders of the Common Stock in
connection with such Change of Control (as determined in good faith by the Board
of Directors, whose determination shall be conclusive and described in a Board
Resolution) consists of cash or securities or other property that is not traded
or scheduled to be traded immediately following such transaction on a U.S.
national securities exchange or the Nasdaq National Market and (c) a holder
elects to convert its Notes pursuant to this Article XV or the Company elects to
convert all or a portion of the Notes pursuant to Section 15.3, in either case
on or

                                       74
<PAGE>
prior to October 15, 2010, then the Conversion Price for any such Notes
surrendered for conversion shall be increased by a number of additional shares
of Common Stock (the "Additional Shares") as described below.

     The number of Additional Shares will be determined by reference to the
table attached as Schedule A hereto, based on the effective date of such Change
in Control (the "Effective Date") and the price (the "Stock Price") paid per
share of the Common Stock in such corporate transaction. If holders of Common
Stock receive only cash in such corporate transaction, the Stock Price shall be
the cash amount paid per share. Otherwise, the Stock Price shall be the average
of the Closing Prices of Common Stock on the five Trading Days up to but not
including the Effective Date of the Change in Control.

     The Stock Prices set forth in the first row of the table in Schedule A
hereto will be adjusted as of any date on which the Conversion Price of the
Securities is adjusted pursuant to Section 15.6. The adjusted Stock Price will
equal the Stock Price applicable immediately prior to such adjustment,
multiplied by a fraction, the numerator of which is the Conversion Price as so
adjusted and the denominator of which is the Conversion Price immediately prior
to the adjustment giving rise to the Stock Price adjustment. In the case of any
such adjustment to the Stock Price, the number of Additional Shares will be
adjusted by multiplying such number by a fraction, the numerator of which is the
Conversion Price immediately prior to such adjustment and the denominator of
which is the Conversion Price, as so adjusted.

     The exact Stock Prices and Effective Dates may not be set forth in the
table in Schedule A, in which case:

          (i) if the Stock Price is between two Stock Price amounts in the table
     or the Effective Date is between two Effective Dates in the table, the
     number of Additional Shares will be determined by a straight-line
     interpolation between the number of Additional Shares set forth for the
     higher and lower Stock Price amounts and the two dates, as applicable,
     based on a 365-day year,

          (ii) prior to October 15, 2008, if the Stock Price exceeds $7.50 per
     share, subject to adjustments set forth in Section 15.6, the number of
     Additional Shares will be determined based on the formula reflected in the
     table which has the intent of producing a number of shares equal to the
     interest payable on the Notes through October 15, 2008, less any interest
     paid on the Notes prior to the Effective Date, and divided by the Stock
     Price; after October 15, 2008, holders will not receive any additional
     shares if the stock price exceeds $6.30 per share, and

          (iii) if the Stock Price is less than $3.75 per share, subject to
     adjustments set forth in Section 15.6, no Additional Shares will be issued
     upon conversion.

effective and available for resale of such Common Stock from the twenty-fifth
(25th) Trading Date prior to the Conversion Date to and including the 30th day
after the Conversion Date to the extent required under the Registration Rights
Agreement, (iii) such Common Stock is listed for trading on the Principal Market
(as defined in the Securities Purchase Agreement) and (iv) that there are enough
authorized but unissued shares of Common Stock available for that purpose.

                                REPURCHASE RIGHT

     Section 16.1 Repurchase Right

     If, at any time prior to October 15, 2025 there shall occur a Repurchase
Event (as defined in Section 16.3), then each holder shall have the right, at
such holder's option, to require the Company to repurchase all of such holder's
Notes, or any portion thereof (in principal amounts of One Thousand United
States Dollars ($1,000) or integral multiples thereof), on the date set by the
Company (a "Repurchase Date") that is no earlier than the Business Day
immediately following the earliest date permitted under Rule 13e-4 or Rule 14e-1
under the Exchange Act (or any successor rule), if either such rule is
applicable, and no later than sixty (60) calendar days after the date of the
Company Notice (as defined in Section 16.2(a) below) of such Repurchase Event
(or, if such 60th day is not a Business Day, the next succeeding Business Day).
Such repurchase shall be made in cash at a price equal to 100% of the principal
amount of Notes such holder elects to require the Company to repurchase
together, in each case, with accrued interest, if any, to, but excluding, the
applicable Repurchase Date (the "Repurchase Price"); provided, that if the
relevant Repurchase Date occurs after a record date or special record date and
before the related Interest Payment Date or special interest payment date, the
amount payable on such Interest Payment Date or special interest payment date
shall be paid to the record holder at the close of business on the record date
or special record date as provided in Section 2.3 and shall not constitute part
of the Repurchase Price.

     In addition, Notes shall be purchased by the Company at the option of the
holder on October 15, 2010, October 15, 2015 and October 15, 2020 (each, also a
"Repurchase Date"), at the Repurchase Price.

     Notwithstanding anything in this Article XVI to the contrary, if a
redemption date pursuant to Article III shall occur prior to any Repurchase Date
established pursuant to a Company Notice under Section 16.2, provided that the
Company shall have deposited or set aside an amount of

                                       76
<PAGE>
money sufficient to redeem such Notes as set forth in Section 3.2 on or before
such Repurchase Date, all such Notes shall be redeemed pursuant to Article III
and the repurchase rights hereunder shall have no effect.

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

     (a) Unless the Company shall have theretofore called for redemption all of
the outstanding Notes and deposited or set aside an amount of money sufficient
to redeem such Notes on the redemption date as set forth in Section 3.2, on or
before (x) the tenth (10th) calendar day following the occurrence of a
Repurchase Event and (y) September 1, 2010, September 1, 2015 and September 1,
2020, the Company or, at the written request of the Company, the Trustee, shall
send to all holders of record of the Notes a notice (the "Company Notice") of
the repurchase right set forth herein arising as of the result of the occurrence
of a Repurchase Event or on October 15, 2010, October 15, 2015 or October 15,
2020, as applicable. The Company shall also deliver a copy of such notice to the
Trustee. The Company Notice shall contain the following information:

          (1) a brief description of the Repurchase Event, if applicable;

          (2) the Repurchase Date;

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

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

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

          (6) the Repurchase Price;

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

          (8) if applicable, that Additional Shares are expected to become
     issuable pursuant to Section 15.13 as a result of the Change of Control and
     the method for calculating the number of Additional Shares to be issued;
     and

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

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

     (b) To exercise a repurchase right, a holder shall deliver to the Trustee
on or before the close of business on the last Business Day prior to the
Repurchase Date (i) written notice to the

                                       77
<PAGE>
Company (or agent designated by the Company for such purpose) of the holder's
exercise of such right in substantially the form attached hereto as Exhibit C

the holder, the principal amount of the Notes to be repurchased and a statement
that an election to exercise the repurchase right is being made thereby, and

duly endorsed for transfer to the Company. Election of repurchase by a holder
shall be revocable at any time prior to the close of business on the last
Business Day prior to the Repurchase Date, by delivering written notice to that
effect to the Trustee.

     (c) If the Company fails to repurchase on the Repurchase Date any Notes (or
portions thereof) as to which the repurchase right has been properly exercised,
then the principal of such Notes shall, until paid, bear interest to the extent
permitted by applicable law from the Repurchase Date at the rate borne by the
Note and each such Note shall be convertible into Common Stock in accordance
with this Indenture until the principal of such Note shall have been paid or
duly provided for.

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

     (e) On or prior to 1:00 p.m., Minneapolis time on the Repurchase Date, the
Company shall deposit with the Trustee or with a paying agent (or, if the
Company is acting as its own paying agent, segregate and hold in trust as
provided in Section 5.4) the Repurchase Price in cash for payment to the holder
on the Repurchase Date. If on or after the Repurchase Date the Company shall
have deposited (or segregated and be holding in trust) funds sufficient to pay
the Repurchase Price of all Notes (or portions thereof) as to which the holders
have duly exercised their repurchase rights pursuant to this Section 16.2, then
on and after such date interest on such Notes (or portions thereof) shall cease
to accrue and such Notes shall cease at the close of business on such date to be
convertible into Common Stock and, except as provided in Section 8.5 and 13.4,
to be entitled to any benefit or security under this Indenture and the holders
thereof shall have no right in respect of such Notes except the right to receive
the Repurchase Price of such Notes (or portions thereof), without interest
thereon from the Repurchase Date.

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

                                       78
<PAGE>
     (g) All Notes delivered for repurchase shall be delivered to the Trustee to
be canceled in accordance with the provisions of Section 2.8.

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

     (i) When complying with the requirements of this Article XVI, the Company
shall comply with the requirements of Rules 13e-4 and 14e-1 (or any successor
rules) under the Exchange Act and any other federal or state securities laws to
the extent such laws are applicable at the time to such actions under this
Article XVI.

     This Indenture is hereby made subject to, and shall be governed by, the
provisions of the Trust Indenture Act required to be part of and to govern
indentures qualified under the Trust Indenture Act; provided, however, that this
Section 17.7 shall not require that this Indenture or the Trustee be qualified
under the Trust Indenture Act prior to the time such qualification is in fact
required under the terms of the Trust Indenture Act, nor shall it constitute any
admission or acknowledgment by any party hereto that any such qualification is
required prior to the time such qualification is in fact required under the

     The Trustee may appoint an authenticating agent which shall be authorized
to act on its behalf and subject to its direction in the authentication and
delivery of Notes in connection with the original issuance thereof and transfers
and exchanges of Notes hereunder, including under Sections 2.4, 2.5, 2.6, 2.7,
3.3, 15.2, 15.3 and 16.2, as fully for all intents and purposes as though the
authenticating agent had been expressly authorized by this Indenture and those
Sections to authenticate and deliver Notes. For all purposes of this Indenture,
the authentication and delivery of Notes by the authenticating agent shall be
deemed to be authentication and delivery of such Notes "by the Trustee" and a
certificate of authentication executed on behalf of the Trustee by an
authenticating agent shall be deemed to satisfy any requirement hereunder or in
the Notes for the Trustee's certificate of authentication. Such authenticating
agent shall at all times be a Person eligible to serve as trustee hereunder
pursuant to Section 8.9.

     Any corporation into which any authenticating agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any authenticating agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of any authenticating agent, shall be the successor
of

                                       83
<PAGE>
the authenticating agent hereunder, if such successor corporation is otherwise
eligible under this Section, without the execution or filing of any paper or any
further act on the part of the parties hereto or the authenticating agent or
such successor corporation.

     Any authenticating agent may at any time resign by giving written notice of
resignation to the Trustee and to the Company. The Trustee may at any time
terminate the agency of any authenticating agent by giving written notice of
termination to such authenticating agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee
shall promptly appoint a successor authenticating agent (which may be the
Trustee), shall give written notice of such appointment to the Company and shall
send notice of such appointment to all holders of Notes as the names and
addresses of such holders appear on the Note Register.

     The Company agrees to pay to the authenticating agent from time to time
reasonable compensation for its services.

     The provisions of Sections 8.2, 8.3, 8.4, 9.3 and this Section 17.10 shall
be applicable to any authenticating agent.

     Section 17.11 Execution in Counterparts

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

     Section 17.12 No Adverse Interpretation of Other Agreements

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

includes any successor corporation under the Indenture referred to on the
reverse hereof), for value received hereby promises to pay to ____________, or
registered assigns, the principal sum of ___________ United States Dollars on
October 15, 2025 and to pay interest on said principal sum semi-annually on
April 15 and October 15 of each year (each, an "Interest Payment Date"),
commencing April 15, 2006, at the rate per annum specified in the title of this
Note, accrued from the most recent date to which interest has been paid or, if
no interest has been paid, from October 7, 2005. The interest so payable on any
April 15 or October 15 will be paid to the person in whose name this Note (or
one or more Predecessor Notes) is registered at the close of business on the
record date, which shall be the 4th day of the month in which the Interest
Payment Date shall occur, whether or not such date is a Business Day; provided
that any such interest not punctually paid or duly provided for shall be payable
as provided in the Indenture. Each payment of interest on this Note shall
include interest to, but excluding, the date of such payment. Payment of the
principal of and interest accrued on this Note (including Liquidated Damages, if
any) shall be made at the office or agency of the Company maintained for that
purpose, which shall initially be the office or agency of the Trustee in
Minneapolis, Minnesota, specified in the Indenture, or at any other office or
agency permitted by the Indenture, in such lawful money of the United States of
America as at the time of payment shall be legal tender for the payment of
public and private debts; provided, that interest may, at the option of the
Company, be paid by check mailed to the address of the holder hereof on the Note
Register; provided further, however, that, with respect to any holder of Notes
with an aggregate principal amount equal to or in excess of Five Hundred
Thousand United States Dollars ($500,000), interest on such holder's Notes shall
be paid by wire transfer in immediately available funds to any bank located in
the United States in accordance with the written wire transfer instruction
supplied by such holder from time to time to the Trustee and paying agent (if
different from the Trustee) in writing at least five (5) Business Days prior to
the applicable record date.

     Reference is made to the further provisions of this Note set forth on the
reverse hereof, including, without limitation, provisions giving a holder of
this Note the right to convert this Note into Common Stock of the Company on the

purposes have the same effect as though fully set forth at this place.

     This Note shall be deemed to be a contract made under the laws of the State
of New York and for all purposes shall be construed in accordance with the
internal laws of the State of New York without giving effect to any choice of

                                ATS MEDICAL, INC.

                       6% Convertible Senior Note due 2025

     This Note is one of a duly authorized issue of Notes of the Company,
designated as its 6% Convertible Senior Notes due 2025 (herein called the
"Notes"), limited (except as otherwise provided in the Indenture) to the
aggregate principal amount outstanding of _______________ United States Dollars,
($____________) all issued or to be issued under and pursuant to an Indenture
dated as of October 7, 2005 (herein called the "Indenture"), between the Company
and Wells Fargo Bank, National Association (herein called the "Trustee"), to
which the Indenture and all indentures supplemental thereto reference is hereby
made for a full description of the rights, limitations of rights, obligations,
duties and immunities thereunder of the Trustee, the Company and the holders of
the Notes. All capitalized terms used herein without definition shall have the
meaning set forth in the Indenture.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of and premium, if any, on all Notes
and the interest accrued thereon (including Liquidated Damages to the extent
accrued and unpaid) may be declared, and upon said declaration shall become, due
and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture. Liquidated damages paid pursuant to Section 15.2 of
the Indenture, if any, shall be paid within ten (10) Business Days after the end
of each month with respect to which such liquidated damages have accrued
pursuant to Section 15.2 in the same manner as interest is paid. Liquidated
Damages on the Notes paid pursuant to Section 2(f) of the Registration Rights
Agreement, if any, shall be paid at the times and in the manner provided
therein.

     The Indenture contains provisions permitting the Company and the Trustee in
certain limited circumstances, without the consent of the holders of the Notes,
and in other circumstances, with the consent of the holders of not less than a
majority in aggregate principal amount of the Notes at the time outstanding,
evidenced as in the Indenture provided, to execute amendments to the Indenture
or supplemental indentures adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of any supplemental
indenture or modifying in any manner the rights of the holders of the Notes;
provided, however, that no such amendment or supplemental indenture shall (i)
extend the fixed maturity of any Note, or reduce the rate or extend the time of
payment of interest thereon, or reduce the principal amount thereof or premium,
if any, thereon, or reduce any amount payable on redemption or repurchase
thereof, impair or change in any respect adverse to the holder of Notes the
obligation of the Company to repurchase any Note at the option of the holder in
accordance with Article XVI of the Indenture, or impair or adversely affect the
right of any Noteholder to institute suit for the payment thereof, or change the
currency in which the Notes are payable, or impair or change in any respect
adverse to the Noteholders the right to convert the Notes into Common Stock
subject to the terms set forth in the Indenture, including Section 15.6, or to
subordinate the Notes in right of payment to other indebtedness, in each such
case without the consent of the holder of each Note so affected, or (ii) reduce
the aforesaid percentage of Notes, the

                                       A-4
<PAGE>
holders of which are required to consent to any such supplemental indenture,
without the consent of the holders of all Notes then outstanding. In addition,
any amendment or supplemental indenture that disproportionately affects the
rights of a Noteholder or a class of Noteholder shall require the prior consent
of such Noteholder or the prior consent of Noteholders holding a majority of the
principal amount of Notes then held by such class, as applicable.

     It is also provided in the Indenture that the holders of not less than a
majority in aggregate principal amount of the Notes at the time outstanding may
on behalf of the holders of all of the Notes waive any past or existing default
or Event of Default under the Indenture and its consequences except (i) a
default in the payment of interest or premium, if any, on, or the principal of,
the Notes when due, (ii) a failure by the Company to convert any Notes into
Common Stock or (iii) a default in respect of a covenant or provisions of the
Indenture which under Article XI thereof cannot be modified or amended without
the consent of all affected holders of Notes then outstanding.

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

     The Notes are issuable in registered form without coupons in denominations
of One Thousand United States Dollars ($1,000) principal amount and integral
multiples thereof. At the office of the Trustee or the Company referred to on
the face hereof, and in the manner and subject to the limitations provided in
the Indenture, without payment of any service charge but with payment of a sum
sufficient to cover any tax, assessments or other governmental charges that may
be imposed in connection with any exchange or registration of transfer of Notes,
Notes may be exchanged for a like aggregate principal amount of Notes of other
authorized denominations. All transfers are subject to the restrictions thereon
provided in the Indenture.

     From and after October 20, 2008, the Company may, at its option, redeem all
or any part of the Notes, upon notice as set forth in the Indenture, and the
Company shall pay each holder of Notes redeemed a redemption price equal to the
principal amount of such Notes, plus accrued and unpaid interest thereon, if
any, to, but excluding, the date of redemption, subject to the proviso in the
final sentence of this paragraph. If notice of redemption has been given as
provided in the Indenture, the Notes or portion of Notes called for redemption
shall, unless converted into Common Stock pursuant to the terms of the
Indenture, become due and payable on the date and at the place or places stated
in such notice at the applicable redemption price and interest accrued to, but
excluding, the date fixed for redemption, and on and after such date (unless the
Company shall default in the deposit of the amount of money sufficient to redeem
such Notes) interest on the Notes or portion of Notes so called for redemption
shall cease to accrue and such Notes shall cease after the close of business on
the last Business Day prior to the date fixed for redemption to be convertible
into Common Stock and, except as provided in Sections 8.5 and 13.4 of the
Indenture, to be entitled to any benefit or security under the Indenture, and
the holders of such Notes shall have no right in respect of such Notes except
the right to receive the redemption price and unpaid interest to, but excluding,
the date fixed for redemption. On presentation and surrender of such Notes at a
place of payment specified in such notice, such Notes or the specified portions
thereof to be redeemed shall be paid and redeemed by the Company at the
applicable redemption price and interest accrued thereon to, but excluding, the

                                       A-5
<PAGE>
date fixed for redemption; provided that, if the applicable redemption date
falls after the record date for an Interest Payment Date and before the relevant
Interest Payment Date, then the semi-annual payment of interest becoming due on
such Interest Payment Date shall be paid to the holders of such Notes registered
as such on the relevant record date in the manner provided for the payment of
interest generally and shall not be paid to the holders surrendering the Notes
when they do so.

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

     Upon the occurrence of a "Repurchase Event," the Noteholder has the right,
at such holder's option, to require the Company to repurchase all of such
holder's Notes, or any portion thereof (in the principal amounts of One Thousand
United States Dollars ($1,000) or integral multiples thereof) on the date set by
the Company that is no earlier than the Business Day immediately following the
earliest date permitted under Rule 13e-4 or Rule 14e-1 under the Exchange Act
(or any successor rules), if either such rule is applicable, and no later than
sixty (60) calendar days after the date of the notice of such Repurchase Event
that the Company is required by the Indenture to send (or, if such 60th day is
not a Business Day, the next succeeding Business Day) at a price equal to 100%
of the principal amount of the Notes such holder elects to require the Company
to repurchase together, in each case, with accrued interest, if any, to, but
excluding, the date fixed for repurchase (the "Repurchase Price"); provided that
if such Repurchase Date occurs after a record date or special record date and
before the related Interest Payment Date or special interest payment date, the
amount payable on such Interest Payment Date or special interest payment date,
shall be paid to the recordholder at the close of business on the record date or
special record date as provided in Section 2.3 of the Indenture and shall not
constitute part of the Repurchase Price. In addition, Notes shall be purchased
by the Company at the option of the holder on October 15, 2010, October 15, 2015
and October 15, 2020 (each, also a "Repurchase Date"), at the Repurchase Price.
If a redemption date pursuant to Article III of the Indenture shall occur prior
to any Repurchase Date established pursuant to a Company Notice under Section
16.2 of the Indenture, provided that the Company shall have deposited or set
aside an amount of money sufficient to redeem such Notes as set forth in Section
3.2 of the Indenture on or before such Repurchase Date, all such Notes shall be
redeemed pursuant to Article III of the Indenture and the repurchase rights
under Article XVI of the Indenture shall have no effect.

     Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time following the date of original issuance of the
Notes and prior to the close of business on October 15, 2025 (except that, with
respect to any Note or portion of a Note that shall be called for redemption or
shall have been noticed for automatic conversion, such right shall terminate,
except as otherwise provided in the Indenture, at the close of business on the
last Business Day prior to the date fixed for redemption or automatic conversion
unless the Company shall default in payment due upon redemption or the delivery
of shares on automatic conversion thereof), to convert the principal hereof or
any portion of such principal which is One Thousand United States Dollars
($1,000) or an integral multiple thereof, into that number of fully paid and
non-assessable shares of the Company's Common Stock (as such shares shall then
be constituted), obtained by dividing the principal amount of this Note or
portion thereof surrendered for conversion by the Conversion Price of $4.20, or
such Conversion Price as adjusted from time to time as provided in the
Indenture. In order to exercise the conversion privilege, the holder must take
the actions specified in the Indenture. These actions

                                       A-6
<PAGE>
include (i) delivery of a conversion notice, (ii) if this Note or portion hereof
is surrendered for conversion during the period from the close of business on
the record date for any Interest Payment Date through the close of business on
the last Business Day prior to such Interest Payment Date, pay by wire transfer
of immediately available funds or other method acceptable to the Company, an
amount equal to the interest otherwise payable on such Interest Payment Date on
the principal amount being converted; provided, however, that no such payment
need be made if there shall exist at the time of conversion a default in the
payment of interest on the Notes (subject to certain exceptions specified in the
Indenture), (iii) pay by wire transfer of immediately available funds or other
method acceptable to the Company the transfer taxes, if any, required pursuant
to the Indenture and (iv) surrender the Note to be converted in whole or in
part. No fractional shares of Common Stock or scrip representing fractional
shares shall be issued upon conversion, but a cash adjustment in lieu of such
fractional share will be paid to the holder, as provided in the Indenture.

     If a the holder of this Note elects to convert all or any portion of this
Note into shares of Common Stock and the Company does not have a sufficient
number of authorized shares of Common Stock to deliver upon conversion, the
Company may choose to satisfy all or any portion of its conversion obligation in
cash in the manner prescribed in the Indenture. For purposes of the foregoing
sentence, the Company, when determining whether it has a sufficient number of
authorized shares of Common Stock to deliver upon conversion, may treat as
outstanding any shares reserved (as of the date of this Indenture) by the
Company's Board of Directors for a specific purpose including issuance under any
existing stock option or other equity plan of the Company or other obligation of
the Company to issue shares of Common Stock.

     The Company may, at its option, automatically convert all or a portion of
the Notes (an "Automatic Conversion") at any time prior to October 15, 2025 if
the Closing Price (as defined in the Indenture) per share of the Common Stock
has exceeded one hundred and fifty percent (150%) of the Conversion Price then
in effect for at least fifteen (20) Trading Days within a period of thirty (30)
consecutive Trading Days ending within five (5) Trading Days of the date the
Company gives to all holders of Notes a notice of the Automatic Conversion,
provided that either (x) a registration statement covering the resale of the
Conversion Shares is effective and available for use from the date of the notice
of Automatic Conversion through and including the earlier of the date on which
the Automatic Conversion becomes effective or the last date on which the
registration statement is required to be kept effective under the terms of the
Registration Rights Agreement, or (y) the shares of Common Stock issuable upon
the Automatic Conversion may be sold pursuant to Rule 144(k) under the
Securities Act (assuming, for purposes of such determination, that no recipient
of Conversion Shares is an "affiliate" of the Company within the meaning of such
Rule and that all recipients of Conversion Shares have held the Notes since the
date of their original issuance). The Company may only elect an Automatic
Conversion with respect to all or any part of the Notes if it has, as of the
date of the Automatic Conversion Notice, sufficient shares of Common Stock
authorized and available for issuance on conversion of the Notes so called for
Automatic Conversion. If the effective date of an Automatic Conversion is prior
to October 15, 2008, the Company shall make an additional payment in cash or, at
the election of the Company under certain circumstances, in shares of Common
Stock, to each holder of Notes (or portion thereof) with respect to the Notes
(or portion thereof) converted, in an amount equal to $181.33 per each One
Thousand United States Dollars ($1,000) principal amount of the holder's Notes
(or portion thereof) (the

                                       A-7
<PAGE>
"Company Conversion Provisional Payment"), less the amount of any interest
actually paid on the holder's Notes (or portion thereof) prior to the effective
date of the Automatic Conversion (and, if the relevant Notes are converted after
a record date and before the related Interest Payment Date, less interest
payable on such Notes (or portion thereof) on such Interest Payment Date).
Except as provided in the immediately preceding sentence, if the Automatic
Conversion Date with respect to any Notes (or portions thereof) subject to an
Automatic Conversion occurs following a record date and prior to the related
Interest Payment Date, then unless the Company defaults in its obligation to
deliver the shares of Common Stock issuable on such Automatic Conversion. the
Company shall not be obligated to pay any interest on such Interest Payment
Date, either to the holder of such Notes (or portions thereof) at the close of
business on the relevant record date or to the holder of such Notes (or portions
thereof) to whom the Company issues the shares of Common Stock issuable on the
Automatic Conversion. Common Stock used to pay any Company Conversion
Provisional Payment shall be valued at ninety-five percent (95%) of the Closing
Prices per share of the Common Stock for the ten (10) consecutive Trading Days
ending on and including the second Trading Day immediately preceding the
Conversion Date.

     If the Company elects to convert all or a portion of the Notes pursuant to
its Automatic Conversion right, the Company, or at its request (which must be
received by the Trustee at least five (5) Business Days prior to the date the
Trustee is requested to give notice as described below unless a shorter period
is agreed to by the Trustee), the Trustee in the name of and at the expense of
the Company, shall send or cause to be sent a notice of the Automatic Conversion
not more than thirty (30) days but not less than five (5) days before the date
of effectiveness of the Automatic Conversion as set forth in the Indenture.

     In connection with any redemption of Notes, the Company may arrange for the
purchase and conversion of any Notes not converted prior to the expiration of
such conversion right by an agreement with one or more investment bankers or
other purchasers to purchase such Notes by paying to the Trustee in trust for
the Noteholders, on or before the date fixed for redemption, an amount not less
