Section 2.03                                Series 2007-B2 Loans. 
(a)  WEST shall have the right, pursuant to this Supplement and the
Series 2007-B2 Note Purchase Agreement, to borrow Series 2007-B2
Loans from the Series 2007-B2
Holders up to the Maximum Commitment of the Series 2007-B2 Holders, and
each Series 2007-B2 Holder has severally agreed, pursuant to the Series 2007-B2
Note Purchase Agreement, to make Series 2007-B2 Loans, in each case in
proportion to, and up to the amount of, its Maximum Commitment, on any Funding
Date after the Effective Date and prior to the date on which a Conversion Event
occurs, subject to the satisfaction of all applicable conditions precedent set
forth in Article IV hereof and in Article III of the Series 2007-B2
Note Purchase Agreement.  Each such Series 2007-B2
Loan shall increase the Outstanding Principal Balance of the Series 2007-B2
Note held by such Series 2007-B2 Holder, and each payment of principal to
a Series 2007-B2 Holder in respect of its Series 2007-B2 Note shall
reduce the Outstanding Principal Balance of such Series 2007-B2 Note.  The Indenture Trustee shall maintain a record
of all Series 2007-B2 Loans and repayments made on the Series 2007-B2
Notes and absent manifest error such records shall be conclusive.

 

(b)                                 Each Funding Request for Series 2007-B2
Loans after the Effective Date shall constitute a reaffirmation by WEST that (1) no
Event of Default, Servicer Termination Event or Early Amortization Event has
occurred and is continuing, or would result from the making of such Series 2007-B2
Loan, as of the date of the Funding Request, and (2) the representations
and warranties of WEST contained in the Series 2007-B2 Transaction
Documents are true, correct and complete in all material respects to the same
extent as though made on and as of the date of the Funding Request, except to
the extent such representations and warranties specifically relate to an earlier
date, in which event they shall be true, correct and complete in all material
respects as of such earlier date.

 

(c)                                  WEST shall designate the application of
the proceeds of the Series 2007-B2 Loans made on each Funding Date as
either or both of the following: (i) a Warehouse Loan to be deposited in
the Engine Acquisition Account as provided in Section 3.18 of the
Indenture and used to acquire Additional Engines or to fund Discretionary
Engine Modifications (including Qualified Engine Modifications), in each case
whether or not such acquisition or funding is in connection with a Replacement
Exchange, or (ii) a Collections Loan, to be deposited in the Collections
Account as provided in Section 3.18 of the Indenture and used to increase
the Available Collections Amount on any Payment Date, provided
that the application of any Series 2007-B2 Loan as a Collections Loan
shall be subject to the Available Collections Amount on such Payment Date being
in an amount, calculated without the proceeds of such Collections Loan,
sufficient to fund the payment in full of accrued Base Interest on all Series B
Notes on such Payment Date and all amounts ranking senior thereto as provided
in Section 3.14 of the Indenture.

 

(d)                                 WEST may, on any Payment Date upon at
least five (5) Business Days’ notice to the Series 2007-B2 Holders,
with a copy to the Indenture Trustee, terminate in whole or reduce in part the
aggregate Maximum Commitments of the Series 2007-B2 Holders and the
Maximum Principal Balances of the Series 2007-B2 Notes in an aggregate
amount not to exceed the excess of such Maximum Principal Balances over the
then aggregate Outstanding Principal 

 

9

 

Balance of the Series 2007-B2 Notes; provided
that any partial reduction (based on the ratio of the then Maximum Commitments
of such Series prior to such reduction) of the aggregate Maximum
Commitments of the Series 2007-B2 Holders and the Maximum Principal
Balances of the Series 2007-B2 Notes (i) shall be applied pro rata to the
individual Maximum Commitments of the Series 2007-B2 Holders and the
Maximum Principal Balances of the Series 2007-B2 Notes, respectively, and (ii) shall be accompanied by a proportionate
partial reduction (based on the ratio of the Maximum Commitments of such Series prior
to such reduction) of the aggregate Maximum Commitments of the Series 2007-A2
Holders. Each notice of reduction or termination pursuant to this Section 2.03(d) shall
be irrevocable, and such reduction shall be deemed to occur without any Series 2007-B2
Holder having to surrender its Series 2007-B2 Notes in exchange for a new Series 2007-B2
Note reflecting the reduced Maximum Principal Balance.

 

(e)                                  WEST, on any Payment Date prior to the
occurrence of a Conversion Event, may terminate the agreements of the Series 2007-B2
Holders to make Series 2007-B2 Loans
and repay the Outstanding Principal Balance of the Series 2007-B2 Notes
for the Redemption Price, upon (A) at least five (5) Business Days’
prior written notice to each Series 2007-B2 Holder, with a copy to the
Indenture Trustee, specifying the proposed Payment Date of such termination,
and (B) payment in full of (i) the principal of, and interest on, the
Series 2007-B2 Notes, (ii) Increased Costs, if any, and (iii) all
other amounts then due and payable (or that become due and payable as a result
of such reduction) to a Series 2007-B2 Holder under the Series 2007-B2
Note Purchase Agreement, this Supplement and the Indenture and (c) the
simultaneous termination of the commitments of the Series 2007-A2 Holders
and the payment in full of all amounts owing with respect to the Series 2007-A2
Notes.

 

(f)                                    If any Series 2007-B2 Holder shall
default on its obligation to make a Series 2007-B2 Loan on any Funding Date, one or more of
the other Series 2007-B2 Holders may elect (but shall not be obligated) to
make the Series 2007-B2 Loan
of the defaulting Series 2007-B2 Holder. 
In such event, the Maximum Principal Balance of the Series 2007-B2
Note held by the defaulting Series 2007-B2 Holder and the Maximum
Commitment of the Series 2007-B2 Holder shall be reduced by the amount of
the Series 2007-B2
Loan so made, and the
Maximum Principal Balance of the Series 2007-B2 Note held by the Series 2007-B2
Holder making such Series 2007-B2 Loan
and the Maximum Commitment of such Series 2007-B2 Holder shall be
increased by the amount of such Series 2007-B2 Loan.

 

(g)                                 Upon the occurrence of a Conversion
Event, (i) the right of WEST to borrow under the Series 2007-B2 Notes
shall terminate, (ii) Conversion Step-Up Interest shall begin to accrue on
the Outstanding Principal Balance of the Series 2007-B2 Notes as provided
in Section 2.04(a), and (iii) the Outstanding Principal Balance of
the Series 2007-B2 Notes shall become payable as provided in Section 2.05(a) and
(b), provided, however, that, if all of the Series 2007-B2
Holders and Series 2007-A2 Holders as of the date of the occurrence of any
Conversion Event elect to waive the occurrence of such Conversion Event within
ninety (90) days of such occurrence, such Conversion Event shall be disregarded
as long as such waiver is in effect, except that any such waiver in respect of
a Conversion Event based on the occurrence of the Conversion Date shall not be
for a period extending beyond the first anniversary of such Conversion Date,
unless a Rating Agency Confirmation is obtained with respect to any waiver
extending beyond such first anniversary; and provided,
further, that, if WEST subsequently cures an Early Amortization
Event, Event of Default or Servicer Termination Event that resulted in a 

 

10

 

Conversion Event that was not so waived, WEST may request the Series 2007-B2
Holders and Series 2007-A2 Holders to waive the original occurrence of
such Conversion Event, Early Amortization Event, Event of Default or Servicer
Termination Event and rescind and revoke the consequences described in clause
(i), (ii) and (iii) of this Section 2.03(g) occurring as a
result of such Conversion Event, which waiver, rescission and revocation shall
be effective only if Series 2007-B2 Holders and Series 2007-A2
Holders representing 100% of the Outstanding Principal Balance of the Series 2007-B2
Notes and Series 2007-A2 Notes consent thereto. The termination of any
waiver pursuant to the provisos in the preceding sentence shall be treated as
the occurrence on the date of such termination of the Conversion Event that was
the subject of the waiver.

 

Section 2.04                                Interest Payments; Commitment Fee.

 

(a)                 Interest on Series 2007-B2 Notes.  Interest shall accrue (i) at the Series 2007-B2
Base Interest Rate on the Outstanding Principal Balance of each Series 2007-B2
Note during all or each portion of each Interest Accrual Period from the
Effective Date to (but excluding) the date on which a Conversion Event occurs,
and (ii) at a combined rate equal to the sum of the Series 2007-B2
Base Interest Rate and the Series 2007-B2 Conversion Step-Up Rate on the
Outstanding Principal Balance of each Series 2007-B2 Note during all or
the portion of each Interest Accrual Period from and after the date on which a
Conversion Event occurs, in each case on the basis of actual days elapsed over
a year of 360 days and shall be due and payable in arrears on each Payment Date
for the Interest Accrual Period ending on such Payment Date. The Base Interest
Amount and the Conversion Step-Up Interest Amount for each Interest Accrual
Period shall be calculated separately and paid separately as provided in Section 3.14
of the Indenture and Section 3.02 hereof. All amounts of the Base Interest
Amount and the Conversion Step-Up Interest Amount shall be due and payable on
the earlier to occur of (i) the date on which the Series 2007-B2
Notes have been accelerated in accordance with the provisions of Section 4.02
of the Indenture and (ii) the Series 2007-B2 Final Maturity Date. On
each Reference Date, the Indenture Trustee shall promptly deliver a written
notice to the Series 2007-B2 Holders specifying the Series 2007-B2
Base Interest Rate for the related Interest Accrual Period.

 

(b)                Commitment Fee on Series 2007-B2
Notes.  A fee (the “Commitment
Fee”) shall accrue at the Series 2007-B2 Commitment Fee Rate on
the Unused Commitment of the Series 2007-B2 Holders during all or the
portion of each Interest Accrual Period from the Effective Date to (but
excluding) the date on which a Conversion Event occurs and shall be due and
payable in arrears on each Payment Date for the Interest Accrual Period ending
on such Payment Date.  The Commitment Fee
shall be calculated on the basis of actual days elapsed over a year of 360 days
and shall be due and payable in arrears on each Payment Date for the Interest
Accrual Period ending on (but excluding) such Payment Date.

 

(c)                 Additional Interest. 
If WEST shall fail to pay in full (i) any Base Interest Amount,
Conversion Step-Up Interest Amount or Commitment Fee on any Series 2007-B2
Note when due, (ii) any Increased Costs or (iii) any other amount
becoming due under this Supplement (other than payments of principal on the Series 2007-B2
Notes), WEST shall, from time to time, pay Additional Interest on such unpaid
amounts, to the extent permitted by Applicable Law, to, but not including, the
date of actual payment (after as well as before judgment), for the period
during which such interest or other amount shall be unpaid from the 

 

11

 

due date of such payment to the date of actual payment thereof. Any
such Additional Interest shall be payable at the times and subject to the
priorities set forth in Section 3.02 of this Supplement and Section 3.14
of the Indenture.  All amounts of the
Additional Interest shall be due and payable on the earlier to occur of (i) the
date on the Series 2007-B2 Notes have been accelerated in accordance with
the provisions of Section 4.02 of the Indenture and (ii) the Series 2007-B2
Final Maturity Date.

 

(d)                Maximum Interest Rate. 
In no event shall the interest charged with respect to a Series 2007-B2
Note exceed the maximum amount permitted by Applicable Law.  If at any time the Interest Amount charged
with respect to the Series 2007-B2 Notes exceeds the maximum rate
permitted by Applicable Law, the rate of interest to accrue pursuant to this
Supplement and such Series 2007-B2 Note shall be limited to the maximum
rate permitted by Applicable Law, but any subsequent reductions in One-Month
LIBOR shall not reduce the interest to accrue on such Series 2007-B2 Note
below the maximum amount permitted by Applicable Law until the total amount of
interest accrued on such Series 2007-B2 Note equals the amount of interest
that would have accrued if a varying rate per annum equal to the interest rate
had at all times been in effect.  If the
total amount of interest paid or accrued on the Series 2007-B2 Note under
the foregoing provisions is less than the total amount of interest that would
have accrued if the interest rate had at all times been in effect, WEST agrees
to pay to the Series 2007-B2 Holders an amount equal to the difference
between (a) the lesser of (i) the amount of interest that would have
accrued if the maximum rate permitted by Applicable Law had at all times been
in effect, or (ii) the amount of interest that would have accrued if the
interest rate had at all times been equal to the Interest Amount, and (b) the
amount of interest accrued in accordance with the other provisions of this
Supplement.

 

Section 2.05                                Payments of Principal. 
(a)  On each Payment Date prior to the date on which a Conversion
Event occurs on which there is a Junior Borrowing Base Deficiency, principal
shall be payable on the Series 2007-B2 Notes out of the Series B
Supplemental Principal Payment Amount, to the extent and as provided in
Sections 3.14 and 3.15(b) of the Indenture and in Section 3.02
hereof, provided that, on any Payment Date prior
to the date on which a Conversion Event occurs, the Series 2007-B2 Notes
shall be treated as Warehouse Notes for purposes of Section 3.15(b) of
the Indenture and, on any Payment Date on or after a Conversion Event, the Series 2007-B2
Notes shall be treated as Term Notes for such purposes.

 

(b)                                 (i)  Within ten (10) Business
Days after the occurrence of a Conversion Event (or, if earlier, by the first
Payment Date following the occurrence of a Conversion Event), WEST shall cause
the Administrative Agent to prepare and deliver to the Indenture Trustee and
the Series 2007-B2 Holders a schedule of Scheduled Targeted Principal
Balances for the Series 2007-B2 Notes substantially in the form of Schedule
1 attached hereto.  Payment Date
Number 1 in Schedule 1 shall be on the first Payment Date after the date
on which a Conversion Event occurs, and each succeeding numbered Payment Date
in such Schedule 1 shall occur on each succeeding Payment Date, and the
amount due on each such Payment Date shall be the product of (x) the
Outstanding Principal Balance of the Series 2007-B2 Notes as of the close
of business on the date on which the Conversion Event occurs and (y) the
percentage specified for such Payment Date specified in Schedule 1.  If the Series 2007-B2 Holders and Series 2007-A2
Holders waive the occurrence of a Conversion Event as provided in Section 2.03(g),
the schedules delivered pursuant to this Section 2.05(b)(i) in
respect of such Conversion Event shall 

 

12

 

be of no further force and effect and, upon the termination of such
waiver or the subsequent occurrence of a Conversion Event that is not waived by
the Series 2007-B2 Holders and Series 2007-A2 Holders as provided by Section 2.03(g) hereof,
the Administrative Agent shall deliver a new schedule in accordance with this Section 2.01(b)(i),
calculated as of the date of such termination or the date of such Conversion
Event, as applicable.

 

(ii)                                  On each Payment Date after a Conversion
Event, unless and until the Series 2007-B2 Holders and Series 2007-A2
Holders waive such Conversion Event as provided in Section 2.03(g), the
Scheduled Principal Payment Amount calculated for the Series 2007-B2 Notes
for each such Payment Date shall be payable to the Holders of the Series 2007-B2
Notes on each such Payment Date from amounts deposited in the Series 2007-B2
Series Account on such Payment Date as provided in Section 3.14 of
the Indenture and Section 3.02 of this Supplement.  So long as an Early Amortization Event or an
Event of Default is then continuing, the Outstanding Principal Balance of the Series 2007-B2
Notes shall be payable on each such Payment Date to the extent that amounts are
available for such purpose in accordance with the provisions of Section 3.14
of the Indenture and Section 3.02 of this Supplement.    The then Outstanding Principal Balance of
all Series 2007-B2 Notes shall be due and payable on the earlier to occur
of (i) the date on which the Series 2007-B2 Notes have been
accelerated in accordance with the provisions of Section 4.02 of the
Indenture and (ii) the Series 2007-B2 Final Maturity Date.

 

(c)                                  WEST will have the option to prepay, on
any Payment Date after a Conversion Event (each such Payment Date, an “Optional Redemption Date”), all or any portion of the
Outstanding Principal Balance of the Series 2007-B2 Notes on such Payment
Date, in a minimum amount of Two Hundred Fifty Thousand Dollars ($250,000) in
the case of any prepayment in part, for the Redemption Price together with
accrued interest thereon to the date of such prepayment; provided
that, (i) as a condition to any
such prepayment, the Outstanding Principal Balance of the Series 2007-B2
Notes shall be prepaid by a proportionate amount, such prepayment to be made as
provided in the Series 2007-B2 Supplement, and (ii) as a condition to
any such prepayment in part on a date on which an Early Amortization Event is
continuing, the Outstanding Principal Balance of each other Series of
Notes shall be prepaid in a proportionate amount, such prepayments to be made
as provided in the relevant Supplements. 
WEST may not make such prepayment from funds in the Collections Account,
except to the extent that funds in the Collections Account would otherwise be
payable to WEST in accordance with the terms of this Supplement and the
Indenture, and may make any such prepayment in part from funds in the Series 2007-B2
Series Account, provided that
funds in such Account may be used to fund a prepayment in whole but not in
part.  Any Optional Redemption in
connection with a Refinancing funded with the proceeds of Additional Notes must
be in whole, and any other Optional Redemption financed with funds other than
funds in the Collections Account or the proceeds of Additional Notes may be in
whole or in part.

 

(d)                                 If there is any Balance in the Engine
Acquisition Account at the end of any Delivery Period beginning on a Funding
Date on which Series 2007-B2 Loans were made by the Series 2007-B2
Holders, the portion thereof allocated to the Series 2007-B2 Notes in
accordance with Section 3.03 (b) of the Indenture shall be applied to
the prepayment of the 

 

13

 

Series 2007-B2 Notes as provided in Section 3.16(b) of
the Indenture on the next succeeding Payment Date (the “Acquisition
Redemption Date”) after the end of such Delivery Period.

 

(e)                                  The Scheduled Targeted Principal
Balances for the Series 2007-B2 Notes, as determined pursuant to Section 2.05(b)(i) hereof,
shall be adjusted at the times and in the manner indicated in Section 3.19
of the Indenture.

 

Section 2.06                                Series 2007-B2 Final Maturity Date. 
The unpaid principal amount of the Series 2007-B2 Notes together
with all unpaid interest (including all Additional Interest and Conversion
Step-Up Interest), fees, expenses, costs and other amounts payable by WEST
pursuant to the terms of the Indenture, this Supplement and the other Series 2007-B2
Transaction Documents shall be due and payable in full on the earlier to occur
of (i) the date on which the Series 2007-B2 Notes have been
accelerated in accordance with the provisions of Section 4.02 of the
Indenture and (ii) the Series 2007-B2 Final Maturity Date.

 

Section 2.07                                Manner of Payments. 
All payments of principal and interest on the Series 2007-B2 Notes
payable on each Payment Date shall be paid to the Series 2007-B2 Holders
reflected in the Register as of the related Record Date by wire transfer of
immediately available funds for receipt prior to 1:00 p.m.  (New York City time) on such Payment
Date.  Any payments received by the Series 2007-B2
Holders after 1:00 p.m.  (New York
City time) on any day shall be considered to have been received on the next
succeeding Business Day.

 

Section 2.08                                Increased Costs. 
If due to the introduction of or any change (including, without limitation,
any change by way of imposition or increase of reserve requirements) in or in
the interpretation of any law or regulation or the imposition of any guideline
or request from any central bank or other Governmental Authority after the Series Issuance
Date of the Series 2007-B2 Notes reflecting such change, there shall be an
increase in the cost to a Series 2007-B2 Holder of making or maintaining
any investment in the Series 2007-B2 Note or any interest therein or of
agreeing to purchase or invest in the Series 2007-B2 Note or any interest
therein, as the case may be (other than by reason of any interpretation of or
introduction of or change in laws or regulations relating to Taxes or Excluded
Taxes), such Series 2007-B2 Holder shall promptly submit to WEST, the
Administrative Agent and the Indenture Trustee, a certificate setting forth in
reasonable detail, the calculation of such increased costs incurred by such Series 2007-B2
Holder.  In determining such amount, such
Series 2007-B2 Holder may use any reasonable averaging and attribution
methods, consistent with the averaging and attribution methods generally used
by such Series 2007-B2 Holder in determining amounts of this type.  The amount of increased costs set forth in
such certificate (which certificate shall, in the absence of manifest error, be
prima facie evidence as to such amount) shall be included in the Increased
Costs for the Interest Accrual Period immediately succeeding the date on which
such certificate was delivered (or if such certificate was delivered during the
last Interest Accrual Period, for such last Interest Accrual Period) and to the
extent remaining outstanding, each Interest Accrual Period thereafter until
paid in full.  The Indenture Trustee
shall pay such Increased Costs to such Series 2007-B2 Holders as part of
the Increased Costs out of the Available Collections Amount on each Payment
Date as provided in Section 3.14 of the Indenture and Section 3.02
hereof.

 

Section 2.09                                Increased Capital. 
If the introduction of or any change in or in the interpretation of any
law or regulation or the imposition of any guideline or request from any 

 

14

 

central bank or other Governmental Authority reflecting such change
after the Series Issuance Date of the Series 2007-B2 Notes affects or
would affect the amount of capital required or expected to be maintained by any
Series 2007-B2 Holder, and such Series 2007-B2 Holder determines that
the amount of such capital is increased as a result of (i) the existence
of the Series 2007-B2 Holder’s agreement to make or maintain an investment
in the Series 2007-B2 Notes or any interest therein and other similar
agreements or facilities, or (ii) the existence of any agreement by Series 2007-B2
Holders to make or maintain an investment in the Series 2007-B2 Notes or
any interest therein or to fund any such investment and any other commitments
of the same type, such Series 2007-B2 Holder shall promptly submit to
WEST, the Administrative Agent and the Indenture Trustee a certificate setting
forth, in reasonable detail, the calculation of the additional amounts required
to compensate such Series 2007-B2 Holder in light of such
circumstances.  In determining such
amount, such Series 2007-B2 Holder may use any reasonable averaging and
attribution methods, consistent with the averaging and attribution methods
generally used by such Series 2007-B2 Holder in determining amounts of
this type.  The amount set forth in such
certificate (which certificate shall, in the absence of manifest error, be
prima facie evidence as to such amount) shall be included in the Increased
Costs for the Interest Accrual Period immediately succeeding the date on which
such certificate was delivered, and to the extent remaining outstanding, each Interest
Accrual Period thereafter until paid in full. 
The Indenture Trustee shall pay such Increased Costs to such Series 2007-B2
Holders as part of the Increased Costs out of the Available Collections Amount
on each Payment Date as provided in Section 3.14 of the Indenture and Section 3.02
hereof.

 

Section 2.10                                Payments of Principal and Interest. 
(a)  Any and all payments and deposits required to be made under
this Supplement, the Series 2007-B2 Notes or the Indenture by WEST or the
Indenture Trustee to or for the benefit of a Series 2007-B2 Holder shall
be made, to the extent allowed by law, free and clear of and without deduction
for any and all present or future taxes, levies, imposts, deductions, charges
or withholdings, and all liabilities with respect thereto, now or hereafter
imposed, levied, collected, withheld or assessed by any Governmental
Authority.  If, as a result of any change
in law, treaty or regulation or in the interpretation or administration thereof
by any governmental or regulatory agency or body charged with the
administration or interpretation thereof, or the adoption of any law, treaty or
regulation, any taxes, levies, imposts, duties, charges or fees (all of the
foregoing collectively, “Taxes”) are
required to be withheld from any amount payable to any Series 2007-B2
Holder hereunder, the amount so payable to such Series 2007-B2 Holder
shall be increased to the extent necessary to yield to such Series 2007-B2
Holder (after payment of all taxes, levies, imposts, duties, charges or fees)
the amount stated to be payable to such Series 2007-B2 Holder hereunder
(such increase and any similar increase described in this Section 2.10(a),
a “Section 2.10(a) Amount”); provided, however, that this sentence shall not apply with
respect to (i) income taxes (including, without limitation, branch profits
taxes, minimum taxes and taxes computed under alternative methods, at least one
of which is based on net income) and franchise taxes that are based on income
or any other tax upon or measured by income or gross receipts imposed on any Series 2007-B2
Holder, in each case, as a result of a present or former connection (other than
any connection arising out of the transactions contemplated by this Supplement)
between the jurisdiction of the government or taxing authority imposing such
tax and such Series 2007-B2 Holder; (ii) any taxes, levies, imposts,
duties, charges or fees that would not have been imposed but for the failure by
such Series 2007-B2 Holder to provide and keep current any certification or
other documentation permitted by Applicable Law to be delivered by such Series 2007-B2

Holder and required to qualify for an exemption from or reduced rate
thereof; (iii) any taxes, levies, imposts, duties, charges or fees imposed
as a result of a change by any Series 2007-B2 Holder of the office through
which the Series 2007-B2 Note or any interest hereunder is acquired,
accounted for or booked as a result of the sale, transfer or assignment by any Series 2007-B2
Holder of its interest hereunder, other than any such taxes, levies, imposts,
duties, charges or fees imposed as a result of any such change or adoption
occurring after any such Series 2007-B2 Note or interest therein is
acquired, accounted for or booked; (iv) taxes measured by income, gross
receipts, assets or capital of any Series 2007-B2 Holder by the taxing
authority of the jurisdiction where such Series 2007-B2 Holder is
organized, incorporated, managed, controlled or is considered to be doing
business or in which it maintains an office, branch or agency (other than Taxes
imposed on the gross amount of any payments made to such Series 2007-B2
Holder under this Supplement without regard to such place of origination or
incorporation, such management or control, the conduct of such business or the
maintenance of such office, branch or agency); (v) any Taxes imposed on
such Series 2007-B2 Holder as a result of payments not related to this
Supplement; and (vi) any withholding tax with respect to any Series 2007-B2
Holder that has not provided the documentation referred to in Section 2.10(c) (all
such exclusions being hereinafter called “Excluded Taxes”).  To the extent that any Series 2007-B2
Holder actually realizes a tax benefit on its income tax returns (whether by
reason of a deduction, credit or otherwise) (a “Tax Benefit”)
for a given year that is attributable to the payment by WEST or the Indenture
Trustee of any such Taxes on behalf of such Series 2007-B2 Holder, such Series 2007-B2
Holder shall reimburse WEST for the amount of such Tax Benefit, it being
understood that the taking of any action to realize any Tax Benefit shall be
within the sole discretion of such Series 2007-B2 Holder; provided,
however, that for purposes of reimbursing WEST, such Series 2007-B2 Holder
shall calculate the amount of the Tax Benefit realized that is attributable to
WEST’s or the Indenture Trustee’s payment of such Taxes on behalf of such Series 2007-B2
Holder as if such Series 2007-B2 Holder realized or received such Tax
Benefit pro rata with all other Tax Benefits available to it for such year.

 

(b)                                 Each of WEST and, to the extent not
prohibited by Applicable Law (including the Code), each Series 2007-B2
Noteholder agrees that, with respect to all federal, state and local income
taxes, it will treat the Series 2007-B2 Notes as indebtedness.

 

(c)                                  Any Section 2.10(a) Amounts
payable to a Series 2007-B2 Holder hereunder shall be included in the
Increased Costs (i) for the Interest Accrual Period in respect of which
the payment subject to withholding is made and (ii) to the extent
remaining outstanding, each Interest Accrual Period thereafter until paid in
full.  The Indenture Trustee shall pay
such Section 2.10(a) Amounts to the Series 2007-B2 Holders as
part of the Increased Costs out of the Available Collections Amount on each
Payment Date as provided in Section 3.14 of the Indenture and Section 3.02
hereof.

 

(d)                                 Each Series 2007-B2 Holder not
organized under the laws of the United States or a State thereof shall, to the
extent that it is entitled to receive payments under this Supplement without
deduction or withholding of any United States federal income taxes (other than
withholding Taxes), provide a W-8 ECI, W-8 BEN or any other information
and documentation that may be necessary in order to obtain such exemption.

Section 2.11                                Breakage Costs. 
If (i) any payment of principal on any Series 2007-B2 Loan is made on a day other than a
Payment Date, or (ii) any Series 2007-B2 Loan requested by WEST is not, for any
reason whatsoever related to a default or nonperformance by WEST, made or
effectuated, as the case may be, on the date specified therefor, WEST shall
indemnify the Series 2007-B2 Holders against any reasonable loss, cost or
expense incurred by the Series 2007-B2 Holders, including, without
limitation, any loss (excluding loss of anticipated profits), cost or expense
incurred by reason of the liquidation or reemployment of deposits or other
funds acquired by the Series 2007-B2 Holders to fund or maintain such Series 2007-B2
Loan during such Interest
Accrual Period.  The Indenture Trustee
shall pay any amounts due under this Section 2.11 to the Series A
Holders as part of the Increased Costs out of the Available Collections Amount
on each Payment Date as provided in Section 3.14 of the Indenture and Section 3.02
hereof.

Holders and Series 2007-A2 Holders as provided by Section 2.03(g) hereof,
the Indenture Trustee shall not register any transfer of a Series 2007-B2
Note, in whole or in part, unless the transferee of such Series 2007-B2
Note is an Eligible Transferee and executes and delivers to the Indenture
Trustee an Assignment and Assumption of the transferor’s obligations under the Series 2007-B2
Note Purchase Agreement to make the Series 2007-B2 Loans in an amount equal to the excess
of the Maximum Principal Balance of the Series 2007-B2 Note being

FORM OF SERIES 2007-B2 NOTE

 

Except as specified in Section 2.12(f) of the Indenture, each 144A
Book-Entry Note, each Unrestricted Book-Entry Note and each Definitive Note
issued in reliance on Section 4(2) of the Securities Act (and all
Notes issued in exchange therefor or upon registration of transfer or
substitution thereof) shall bear the following legend on the face thereof:

 

THIS NOTE HAS NOT BEEN REGISTERED UNDER THE U.S.
SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR WITH ANY
SECURITIES REGULATORY AUTHORITY IN ANY JURISDICTION AND, ACCORDINGLY, MAY NOT
BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE.  BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS
THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A
UNDER THE SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL “ACCREDITED
INVESTOR” (AS DEFINED IN RULE 501(a)(1), (2), (3) OR (7) OF
REGULATION D UNDER THE SECURITIES ACT) (AN “INSTITUTIONAL ACCREDITED INVESTOR”)
OR (C) IT IS NOT A U.S. PERSON (WITHIN THE MEANING OF REGULATION S) AND IS
ACQUIRING THIS NOTE IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 OF
REGULATION S UNDER THE SECURITIES ACT, (2) AGREES THAT IT WILL NOT BEFORE
TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUE DATE OF THIS NOTE AND THE LAST
DATE THAT WILLIS ENGINE SECURITIZATION TRUST, A DELAWARE STATUTORY TRUST (“WEST”),
OR ANY OF ITS AFFILIATES OWNED THIS NOTE, RESELL OR OTHERWISE TRANSFER THIS
NOTE EXCEPT (A) TO WEST OR ANY SUBSIDIARY THEREOF, (B) TO A QUALIFIED
INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) TO
AN INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO
THE INDENTURE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS NOTE (THE FORM OF
WHICH LETTER CAN BE OBTAINED FROM THE INDENTURE TRUSTEE) AND AN OPINION OF
COUNSEL ACCEPTABLE TO WEST THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES
ACT, (D) IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 OF
REGULATION S UNDER THE SECURITIES ACT, (E) PURSUANT TO AN EXEMPTION FROM
REGISTRATION IN ACCORDANCE WITH RULE 144 UNDER THE SECURITIES ACT (IF
AVAILABLE), OR PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM REGISTRATION UNDER
THE SECURITIES ACT, OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
UNDER THE SECURITIES ACT AND, IN EACH OF CASES (A) THROUGH (F) ABOVE,
IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE IN THE UNITED
STATES OR ANY OTHER APPLICABLE JURISDICTION, AND (3) AGREES THAT IT WILL
DELIVER TO EACH PERSON TO WHOM THIS NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY
TO THE EFFECT OF THIS LEGEND.  IN
CONNECTION WITH ANY TRANSFER OF THIS NOTE WITHIN THE TWO-YEAR PERIOD REFERRED
TO ABOVE, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON

 

A-1

 

THE TRANSFER NOTICE ATTACHED HERETO AND SUBMIT SUCH
TRANSFER NOTICE TO THE INDENTURE TRUSTEE. 
IF THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR OR IF
THE TRANSFER IS PURSUANT TO AN EXEMPTION FROM REGISTRATION IN ACCORDANCE WITH
RULE 144 UNDER THE SECURITIES ACT, THE HOLDER MUST, PRIOR TO SUCH TRANSFER,
FURNISH TO THE INDENTURE TRUSTEE AND WEST SUCH CERTIFICATIONS, LEGAL OPINIONS
OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT
SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION
NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.  AS USED HEREIN, THE TERMS “OFFSHORE
TRANSACTION,” “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANINGS GIVEN TO THEM
BY REGULATION S UNDER THE SECURITIES ACT. 
THE INDENTURE CONTAINS A PROVISION REQUIRING THE INDENTURE TRUSTEE TO
REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING
RESTRICTIONS.

 

Each Book-Entry Note shall also bear the following
legend on the face thereof:

 

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

 

TRANSFERS OF THIS BOOK-ENTRY NOTE SHALL BE LIMITED TO
TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A
SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS
BOOK-ENTRY NOTE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE
RESTRICTIONS SET FORTH IN SECTION 2.12 OF THE INDENTURE.

KNOW ALL PERSONS BY THESE
PRESENTS that WILLIS ENGINE SECURITIZATION TRUST, a Delaware statutory trust (“WEST”), for value received, hereby promises to pay to
[                              ],
or registered assigns, at the principal corporate trust office of the Indenture
Trustee named below, (i) the principal amount of the Series 2007-B2
Loans made by the holder hereof to WEST in an amount up to the Maximum
Principal Balance of                 
Dollars ($                ),
which principal amount shall be payable on each Payment Date on the dates and
in the amounts set forth in the Indenture, dated as of August 9, 2005 and
amended and restated as of December 13, 2007 (as amended, restated or otherwise
modified from time to time, the “Indenture”),
and the Series 2007-B2
Supplement, dated as of December 13, 2007 (as amended, restated or otherwise
modified from time to time, the “Series 2007-B2 Supplement”),
each between WEST and Deutsche Bank Trust Company Americas, as indenture
trustee (the “Indenture Trustee”), and (ii) interest
on the outstanding principal amount of this Series 2007-B2 Floating Rate
Secured Note (this “Series 2007-B2 Note”) on the
dates and in the amounts set forth in the Indenture and the Series 2007-B2 Supplement. Capitalized
terms not otherwise defined herein will have the meaning set forth in the
Indenture and the Series 2007-B2 Supplement.

 

Payment of the principal
of, interest on and Increased Costs for this Series 2007-B2 Note shall be made in
lawful money of the United States of America which at the time of payment is
legal tender for payment of public and private debts. The principal balance of,
and interest on, this Series 2007-B2
Note and any Increased Costs are payable at the times and in the amounts set
forth in the Indenture and the Series 2007-B2 Supplement by wire transfer of immediately available
funds to the account designated by the Holder of record on the related Record
Date.

 

This Series 2007-B2 Note is one of the
authorized notes identified in the title hereto and issued pursuant to the
Indenture and the Series 2007-B2
Supplement.

 

The Series 2007-B2 Notes shall be an
obligation of WEST and shall be secured by the Collateral, all as defined in,
and subject to limitations set forth in, the Indenture.

 

This Series 2007-B2 Note is transferable as
provided in the Indenture and the Series 2007-B2 Supplement, subject to certain limitations therein
contained, only upon the books for registration and transfer kept by the
Indenture Trustee, and only upon surrender of this Series 2007-B2 Note for
transfer to the Indenture Trustee duly endorsed by, or accompanied by a written
instrument of transfer and an assumption of the obligation of the transferor to
make the Series 2007-B2
Loans in form reasonably satisfactory to the Indenture Trustee duly
executed by, the registered Holder hereof or his attorney duly authorized in
writing.  The Indenture Trustee shall not
recognize any transfer of this Series 2007-B2 Note prior to the occurrence of a

 

A-3

 

Conversion Event, unless
the transferee meets the requirements for an Eligible Transferee in the Series 2007-B2 Supplement and agrees to
make the Series 2007-B2
Loans up to an amount equal to the excess of the Maximum Principal
Balance of this Series 2007-B2
Note at the time of transfer over the Outstanding Principal Balance of this Series 2007-B2
Note at such time. The Indenture Trustee or WEST may require payment by the
Holder of a sum sufficient to cover any tax expense or other governmental
charge payable in connection with any transfer or exchange of the Series 2007-B2 Notes.

 

WEST, the Indenture
Trustee and any other agent of WEST may treat the Person in whose name this Series 2007-B2 Note is registered as the
absolute owner hereof for all purposes, and neither WEST, the Indenture
Trustee, nor any other such agent shall be affected by notice to the contrary.

 

The Series 2007-B2 Notes are subject to
Optional Redemption, at the times and subject to the conditions set forth in
the Indenture and the Series 2007-B2
Supplement.

 

If an Event of Default
under the Indenture shall occur and be continuing, the principal of and accrued
interest on this Series 2007-B2 Note may be declared to be due and payable in the manner
and with the effect provided in the Indenture and the Series 2007-B2 Supplement.

 

The Indenture permits,
with certain exceptions as therein provided, the issuance of supplemental
indentures with the consent of the Requisite Majority, in certain specifically
described instances. Any consent given by the Requisite Majority shall be
conclusive and binding upon the Holder of this Series 2007-B2 Note and on all future
holders of this Series 2007-B2
Note and of any Series 2007-B2
Note issued in lieu hereof whether or not notation of such consent is made upon
this Series 2007-B2
Note. Supplements and amendments to the Indenture and the Series 2007-B2 Supplement may be made
only to the extent and in circumstances permitted by the Indenture and the Series 2007-B2 Supplement.

 

The Holder of this Series 2007-B2 Note shall have no right
to enforce the provisions of the Indenture and the Series 2007-B2 Supplement or to
institute action to enforce the covenants, or to take any action with respect
to a default under the Indenture and the Series 2007-B2 Supplement, or to institute, appear in or defend any
suit or other proceedings with respect thereto, except as provided under
certain circumstances described in the Indenture and the Series 2007-B2 Supplement; provided, however, that
nothing contained in the Indenture and the Series 2007-B2 Supplement shall affect or impair any right of
enforcement conferred on the Holder hereof to enforce any payment of the
principal of and interest on this Series 2007-B2 Note on or after the due date thereof; provided  further, however, that by acceptance hereof the Holder is deemed to
have covenanted and agreed that it will not institute against WEST any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings,
or other proceedings under any applicable bankruptcy or similar law, at any
time other than at such time as permitted by the Indenture and the Series 2007-B2 Supplement.

 

The indebtedness evidenced by the Notes issued under the Series 2007-B2
Supplement is, to the extent and in the manner provided in the Indenture,
subordinate and subject in right of payment to the prior payment in full of all
Senior Claims (as defined in the Indenture), and this Series 2007-B2 Note
is issued subject to such provisions. Each Holder of this Series 2007-B2

 

A-4

 

Note, by accepting the same, (a) agrees to and shall be bound by
such provisions, (b) authorizes and directs the Indenture Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate the
subordination as provided in the Indenture, and (c) appoints the Indenture
Trustee his attorney-in-fact for such purpose.

 

The maturity of this Series 2007-B2 Note is subject to acceleration
upon the occurrence and during the continuance of the Events of Default
specified in the Indenture. The Holders of the Notes issued under the Series 2007-B2
Supplement shall not be permitted to deliver a Default Notice or to exercise
any remedy in respect of any such Event of Default until all interest on and
principal of the Series A Notes have been paid in full.

 

The Holder of this Series 2007-B2 Note agrees, by acceptance
hereof, to pay over to the Administrative Agent any money (including principal,
premium and interest) paid to it in respect of this Series 2007-B2 Note in
the event that the Indenture Trustee, acting in good faith, determines
subsequently that such monies were not paid in accordance with the priority of
payment provisions of the Indenture or as a result of any other mistake of fact
or law on the part of the Administrative Agent in making such payment.

 

The subordination provisions contained in Section 3.14 and Article XI
of the Indenture may not be amended or modified without the consent of each
Hedge Counterparty, each Holder of the subclass affected thereby and each
Holder of any subclass of Notes ranking senior thereto.

 

The Indenture also contains provisions
permitting the Holders of Notes representing a majority of the Outstanding
Principal Balance of the Senior Series of Notes to waive compliance by
WEST with certain provisions of the Indenture and certain past defaults under
the Indenture and their consequences. Any such consent or waiver shall be
conclusive and binding upon all present and future Holders of this Series 2007-B2
Note and of any Series 2007-B2 Note issued upon the registration of
transfer of, in exchange or in lieu of or upon the refinancing of this Series 2007-B2
Note, whether or not notation of such consent or waiver is made upon this Series 2007-B2
Note.

 

This Series 2007-B2 Note, and the rights and
obligations of the parties hereunder, shall be governed by, and construed and
interpreted in accordance with, the laws of the State of New York without
giving effect to principles of conflict of laws, other than Sections 5-1401 and
5-1402 of the New York General Obligations Laws.

 

All terms and provisions
of the Indenture and the Series 2007-B2 Supplement are herein incorporated by reference as if
set forth herein in their entirety.

 

IT IS HEREBY CERTIFIED,
RECITED AND DECLARED, that all acts, conditions and things required to exist,
happen and be performed precedent to the execution and delivery of the
Indenture and the Series 2007-B2 Supplement and the issuance of this Series 2007-B2
Note and the issue of which it is a part, do exist, have happened and have been
timely performed in regular form and manner as required by law.

 

Unless the certificate of
authentication hereon has been executed by the Indenture Trustee by manual
signature of one of its Responsible Officers, this Series 2007-B2 Note shall not be

 

A-5

 

entitled to any benefit
under the Indenture and the Series 2007-B2 Supplement, or be valid or
obligatory for any purpose.

 

IN WITNESS WHEREOF, WEST
has caused this Series 2007-B2 Note to be duly executed by its duly authorized
representative, as of the date first set above.

Section 2.03.          Interest
Payments on the Series 2008-A1 Notes.

 

(a)           Interest
on Series 2008-A1 Notes. 
Interest on each Series 2008-A1 Note shall (i) accrue during
each Interest Accrual Period at the Series 2008-A1 Stated Rate, (ii) be
calculated on the basis of actual days elapsed over a year of 360 days, (iii) be
due and payable in arrears on each Payment Date, and (iv) be calculated
based on the Outstanding Principal Balance of such Series 2008-A1 Note
during such Interest Accrual Period. All amounts of the
Stated Interest Amount for Series 2008-A1 Notes shall be due and payable
on the earlier to occur of (i) the date on which the Series 2008-A1
Notes have been accelerated in accordance with the provisions of Section 4.02
of the Indenture and (ii) the Series 2008-A1 Final Maturity Date.  The Administrative Agent shall include in the
Monthly Report delivered to the Series 2008-A1 Holders the Series 2008-A1
Stated Rate for the Interest Accrual Period beginning in the month after the
month covered by such Monthly Report.

 

(b)           Additional
Interest.  If WEST shall fail to pay
the Stated Interest Amount on any Series 2008-A1 Note when due, or any
other amount becoming due under this Supplement (other than payments of
principal on the Series 2008-A1 Notes), WEST shall, from time to time, pay
Additional Interest on such unpaid amounts, to the extent permitted by
Applicable Law, to, but not including, the date of actual payment (after as
well as before judgment), for the period during which such interest or other
amount shall be unpaid from the due date of such payment to the date of actual
payment thereof. Any such interest shall be payable at the times and subject to
the priorities set forth in Section 3.03 of this Supplement and Section 3.14
of the Indenture.  All
amounts of Additional Interest shall be due and payable on the earlier to occur
of (i) the date on which the Series 2008-A1 Notes have been
accelerated in accordance with the provisions of Section 4.02 of the
Indenture and (ii) the Series 2008-A1 Final Maturity Date.

 

(c)           Maximum
Interest Rate.  In no event shall the
interest charged with respect to a Series 2008-A1 Note exceed the maximum
amount permitted by Applicable Law.  If
at any time the Interest Amount charged with respect to the Series 2008-A1
Notes exceeds the maximum rate permitted by Applicable Law, the rate of
interest to accrue pursuant to this Supplement and such Series 2008-A1
Note shall be limited to the maximum rate permitted by Applicable Law, but any
subsequent reductions in the One-Month LIBOR shall not reduce the interest to
accrue on such Series 2008-A1 Note below the maximum amount permitted by
Applicable Law until the total amount of interest accrued on such Series 2008-A1
Note equals the amount of interest that would have accrued if a varying rate
per annum equal to the interest rate had at all times been in effect.  If the total amount of interest paid or
accrued on the Series 2008-A1 Note under the foregoing provisions is less
than the total amount of interest that would have accrued if the interest rate
had at all times been in effect, WEST agrees to pay to the Series 2008-A1
Holders an amount equal to the difference between (a) the lesser of (i) the
amount of interest that would have accrued if the maximum rate permitted by
Applicable Law had at all times been in effect, or (ii) the amount of
interest that would have accrued if the interest rate had at all times been
equal to the Interest Amount, and (b) the amount of interest accrued in
accordance with the other provisions of this Supplement.

THIS NOTE HAS NOT BEEN REGISTERED UNDER THE U.S.

THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A
UNDER THE SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL “ACCREDITED
INVESTOR” (AS DEFINED IN RULE 501(a)(1), (2), (3) OR (7) OF
REGULATION D UNDER THE SECURITIES ACT) (AN “INSTITUTIONAL ACCREDITED INVESTOR”)
OR (C) IT IS NOT A U.S. PERSON (WITHIN THE MEANING OF REGULATION S) AND IS
ACQUIRING THIS NOTE IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 OF
REGULATION S UNDER THE SECURITIES ACT, (2) AGREES THAT IT WILL NOT BEFORE
TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUE DATE OF THIS NOTE AND THE LAST

AN INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO

SECURITIES ACT, (D) IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904
OF REGULATION S UNDER THE SECURITIES ACT, (E) PURSUANT TO AN EXEMPTION

THE SECURITIES ACT, OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
UNDER THE SECURITIES ACT AND, IN EACH OF CASES (A) THROUGH (F) ABOVE,
IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE IN THE UNITED
