Series Account or otherwise at the times and in the amounts set forth in Article III
of the Indenture and Sections 2.04, 2.05, 2.06 and 3.02 of this
Supplement.  The Minimum Principal
Payment Amount and Scheduled Principal Payment Amounts for the Series A2
Notes shall be calculated on the date on which a Conversion Event occurs in
accordance with the terms of the Indenture and Section 2.05 of this
Supplement.

 

(d)                                 WEST shall pay
Issuance Expenses out of the proceeds of the Series A2 Notes on the Series Issuance
Date.

 

(e)                                  In the event that any
term or provision contained herein shall conflict with or be inconsistent with
any term or provision contained in the Indenture, the terms and provisions of
this Supplement shall govern.

 

Section 2.02                                Authentication
and Delivery.  (a)  On the Series Issuance
Date, WEST shall sign, and shall direct the Indenture Trustee in writing

otherwise disposed of except to Institutional Accredited Investors and QIB’s
that deliver an Investment Letter to the Indenture Trustee in compliance with
the provisions of the Indenture and that, prior to the occurrence of a
Conversion Event, are Eligible Transferees and execute and deliver an
Assignment and Assumption with respect to the Series A2 Note Purchase
Agreement.

 

(c)                                  The Series 2005-1
Notes shall be represented by one or more Definitive Notes issued to the Series A2
Noteholders until the occurrence of a Conversion Event.  After the occurrence of a Conversion Event,
any Series A2 Noteholder that is a QIB may exchange its Definitive Note

(d)                                 The Series A2
Notes shall be executed by manual or facsimile signature on behalf of WEST by
any officer of the Owner Trustee and shall be substantially in the form of Exhibit A
hereto, as applicable, with the appropriate legend required by Section 2.02
of the Indenture inscribed on the face thereof.

 

(e)                                  The Series A2
Notes shall be issued in minimum denominations of $100,000 and in integral
multiples of $1,000 in excess thereof.

 

Section 2.03                                Loans
under the Series A2 Notes.  (a) 
WEST shall have the right, pursuant to this Supplement and the Series A2
Note Purchase Agreement, to borrow Loans from the Series A2 Noteholders,
and each Series A2 Noteholders has severally agreed, pursuant to the Series A2
Note Purchase Agreement, to make Loans, in each case in proportion to, and up
to the amounts of, its respective Maximum Commitments of the Series A2
Noteholders, on the Initial Closing Date and on any Business Day (a “Funding Date”) thereafter 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 A2 Note Purchase Agreement. 
Each such Loan shall increase the Outstanding Principal Balance of the Series A2
Notes held by such Series A2 Noteholder. 
The Indenture Trustee shall maintain a record of all Loans and
repayments made on the Series A2 Notes and absent manifest error such
records shall be conclusive.

 

(b)                                 Each Funding Request
for Loans after the Initial Closing 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 Loan, as of the date of the Funding Request and (2) the
representations and warranties of WEST contained in the Series A2
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 use the
proceeds of the Loans made on the Initial Closing Date for the purposes
described in the Offering Memorandum and shall use the proceeds of the Loans
made on each subsequent Funding Date for any or all of the following purposes: (i) to
acquire the Third Remaining Engine, (ii) 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 (iii) to increase the Available
Collections Amount on any Payment Date by depositing all or a portion of the
proceeds of a Loan in the Collections Account, provided
that the use of any Loan to increase the Available Collections Amount shall be
subject to the Available Collections Amount on such Payment Date being in an
amount, calculated without the proceeds of such 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 3.13
of the Indenture.

 

(d)                                 WEST may elect to
increase the aggregate Maximum Principal Balances of the Series A2 Notes
and the aggregate Maximum Commitments of the Series A2 Noteholders to an
amount greater than $100,000,000 but not in excess of $150,000,000, subject to
the receipt

 

9

 

of (i) the prior written consent of all of the Series A2
Noteholders and (ii) a Rating Agency Confirmation, provided that, as a condition of any such
increase, the Maximum Principal Balances of the Series B2 Notes and the
Maximum Commitments of the Series B2 Noteholders shall be increased by a
proportionate amount, such increase to be made as provided in the Series B2
Supplement and the Series B2 Note Purchase Agreement.  Any increase pursuant to the preceding
sentence shall be applied to increase the Maximum Principal Balances of the
individual Series A2 Notes and the Maximum Commitments of the Series A2
Noteholders proportionately to the Maximum Principal Balances of the Series A2
Notes held by the Series A2 Noteholders immediately prior to such
increase, and such increases shall be deemed to occur without any Series A2
Noteholder having to surrender its Series A2 Notes in exchange for a new Series A2
Note reflecting the increased Maximum Principal Balance.

 

(e)                                  WEST may, on any
Payment Date upon at least five Business Days’ notice to the Series A2
Noteholders, terminate in whole or reduce in part the aggregate Maximum
Commitments of the Series A2 Noteholders and the Maximum Principal
Balances of the Series A2 Notes in an aggregate amount not to exceed the
excess of such Maximum Principal Balances over the then aggregate Outstanding
Principal Balance of the Series A2 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 A2 Noteholders and the Maximum Principal
Balances of the Series A2 Notes (i) shall be applied pro rata to the
individual Maximum Commitments of the Series A2 Noteholders and the
Maximum Principal Balances of the Series A2 Notes, respectively, and (ii) shall
be accompanied by a proportionate partial reduction of the aggregate Maximum
Commitments of the Series B2 Noteholders. 
Each notice of reduction or termination pursuant to this Section 2.03(e) shall
be irrevocable, and such reduction shall be deemed to occur without any Series A2
Noteholder having to surrender its Series A2 Notes in exchange for a new Series A2
Note reflecting the reduced Maximum Principal Balance.

 

(f)                                    WEST may, on any
Payment Date prior to the occurrence of a Conversion Event terminate the
agreements of the Series A2 Noteholders to make Loans and repay the
Outstanding Principal Balance of the Series A2 Notes for the Redemption
Price, upon (a) at least five (5) Business Days’ prior written notice
to each Series A2 Noteholder, 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 A2
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 A2 Noteholder under this Agreement, the Supplement and the
Indenture and (c) the simultaneous termination of the commitments of the Series B2
Noteholders and the payment in full of all amounts owing with respect to the Series B2
Notes.

 

(g)                                 If any Series A2
Noteholder shall default on its obligation to make a Loan on any Funding Date,
one or more of the other Series A2 Noteholders may elect (but shall not be
required) to make the Loan of the defaulting Series A2 Noteholder.  In such event, the Maximum Principal Balance
of the Series A2 Note held by the defaulting Series A2 Noteholder and
the Maximum Commitment of the Series A2 Noteholder shall be reduced by the
amount of the Loan so made, and the Maximum Principal Balance of the Series A2
Note held by the Series A2 Noteholder making such Loan and the Maximum
Commitment of such Series A2 Noteholder shall be increased by the amount
of such Loan.

(h)                                 Upon the occurrence of
a Conversion Event, (i) the right of WEST to borrow under the Series A2
Notes shall terminate, (ii) Conversion Step-Up Interest shall begin to
accrue on the Outstanding Principal Balance of the Series A2 Notes as
provided in Section 2.04(a), and (iii) the Outstanding Principal
Balance of the Series A2 Notes shall become payable as provided in Section 2.05(a) and
(b), provided, however, that, if
all of the Series A2 Noteholders elect to waive the occurrence of any
Conversion Event, such Conversion Event shall be disregarded as long as such
waiver is in effect; provided, further,
that, if WEST subsequently cures an Early Amortization Event, Event of Default
or Servicer Termination Event that resulted in a Conversion Event that was not
so waived, WEST may request the Series A2 Noteholders to waive the
original occurrence of such Conversion Event, Event of Default or Servicer
Termination Event and rescind and revoke the consequences described in clause
(i), (ii) and (iii) of this Section 2.04(h) occurring as a
result of such Conversion Event, which waiver, rescission and revocation shall
be effective only if Series A2 Noteholders representing 100% of the
Outstanding Principal Balance of the Series 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 A2
Notes.  Interest shall accrue (i) at
the Series A2 Stated Rate on the Outstanding Principal Balance of each Series A2
Note during all or each portion of each Interest Accrual Period from the
Closing 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 A2 Stated
Rate and the Series A2 Conversion Step-Up Rate on the Outstanding
Principal Balance of each Series A2 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 Series A2 Stated Interest Amount and
the Series A2 Conversion Step-Up Interest Amount for each Interest Accrual
Period shall be calculated separately and paid separately as provided in Section 3.13
of the Indenture and Section 3.02 hereof. 
All amounts of the Series A2 Stated Interest Amount and the Series A2
Conversion Step-Up Interest Amount shall be due and payable on the earlier to
occur of (i) the date on which the Series A2 Notes have been
accelerated in accordance with the provisions of Section 4.02 of the
Indenture and (ii) the Series A2 Final Maturity Date.  On each Reference Date, the Indenture Trustee
shall promptly deliver a written notice to the Series A2 Noteholders
specifying the Series A2 Stated Rate for the related Interest Accrual
Period.

 

(b)                                 Commitment Fee on Series A2
Notes.  The Series A2 Commitment
Fee shall accrue at the Series A2 Commitment Fee Rate on the Unused
Commitment of the Series A2 Noteholders during all or the portion of each
Interest Accrual Period from the Closing Date to (but excluding) the date on
which a Conversion Event occurs.  The Series A2
Commitment Fee Amount 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 Series A2 Stated Interest Amount, Series A2
Conversion Step-Up Interest Amount or Series A2 Commitment Fee

 

11

 

on any Series A2 Note when due, (ii) any Series A2
Increased Costs or (iii) any other amount becoming due under this
Supplement (other than payments of principal on the Series A2 Notes), WEST
shall, from time to time, pay Series A2 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 Series A2 Additional Interest
shall be payable at the times and subject to the priorities set forth in Section 3.02
of this Supplement and Section 3.13 of the Indenture.  All amounts of the Series A2 Additional
Interest shall be due and payable on the earlier to occur of (i) the date
on the Series A2 Notes have been accelerated in accordance with the
provisions of Section 4.02 of the Indenture and (ii) the Series A2
Final Maturity Date.

 

(d)                                 Maximum Interest
Rate.  In no event shall the interest
charged with respect to a Series A2 Note exceed the maximum amount
permitted by Applicable Law.  If at any
time the Series A2 Interest Amount charged with respect to the Series A2
Notes exceeds the maximum rate permitted by Applicable Law, the rate of
interest to accrue pursuant to this Supplement and such Series A2 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 A2 Note below the maximum amount permitted by
Applicable Law until the total amount of interest accrued on such Series A2
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 A2 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 A2
Noteholders 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 Series A2 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 Senior Borrowing Base Deficiency, principal shall be payable on the Series A2
Notes out of the Series A Supplemental Principal Payment Amount, to the
extent and as provided in Sections 3.13 and 3.14(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 A2 Notes shall be treated as Warehouse Notes for purposes of Section 3.14(b) of
the Indenture and, on any Payment Date on or after a Conversion Event, the Series A2
Notes shall be treated as other than Warehouse 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 A2 Noteholders a schedule of the Minimum Targeted
Principal Balances and Scheduled Targeted Principal Balances for the Series A2
Notes substantially in the form of Schedules 1 and 2 attached hereto,
respectively, each calculated using the Outstanding Principal Balance of the Series A2
Notes as of the close of business on the date on which the Conversion Event
occurs.  In each case, the first Payment Date
in the schedule shall be on the first Payment

 

12

 

Date after the date on which a Conversion Event occurs.  If the Series A2 Noteholders
subsequently waive the occurrence of Conversion Events as provided in Section 2.03(f),
the schedule delivered pursuant to this Section 2.05(b)(i) shall
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 A2
Noteholders, 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, the Minimum Principal Payment
Amount and the Scheduled Principal Payment Amount calculated for the Series A2
Notes for each such Payment Date shall be payable to the Holders of the Series A2
Notes on each such Payment Date from amounts deposited in the Series A2 Series Account
on such Payment Date as provided in Section 3.13 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 A2 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 3.13 of the Indenture and Section 3.02
of this Supplement.  The then Outstanding
Principal Balance of all Series A2 Notes shall be due and payable on the
earlier to occur of (i) the date on which the Series A2 Notes have
been accelerated in accordance with the provisions of Section 4.02 of the
Indenture and (ii) the Series A2 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 A2
Notes on such Payment Date, in a minimum amount of Two Hundred Fifty Thousand
Dollars ($250,000), for the Redemption Price together with accrued interest
thereon to the date of such prepayment. 
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 A2
Series Account or the Senior Restricted Cash Account, provided that funds
in such Accounts 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
whole or in part.

 

(d)                                 If there is any
Balance in the Engine Acquisition Account at the end of the Delivery Period
beginning on the Initial Closing Date, the portion thereof allocated to the Series A2
Notes in accordance with Section 3.15(b) of the Indenture shall be
applied to the prepayment of the Series A2 Notes as provided in Section 3.16
of the Indenture on the next succeeding Payment Date (the “Acquisition Redemption Date”) after the
end of such Delivery Period.

 

(e)                                  The Minimum Targeted
Principal Balances and the Scheduled Targeted Principal Balances for the Series A2
Notes, as determined pursuant to Section 2.05(b)(i) hereof, shall be
adjusted at the times and in the manner indicated in Section 3.18 of the
Indenture.

 

13

 

Section 2.06                                Series A2
Final Maturity Date.  The unpaid
principal amount of the Series A2 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 A2 Transaction Documents
shall be due and payable in full on the earlier to occur of (i) the date
on which the Series A2 Notes have been accelerated in accordance with the
provisions of Section 4.02 of the Indenture and (ii) the Series A2
Final Maturity Date.

 

Section 2.07                                Manner
of Payments.  All payments of
principal and interest on the Series A2 Notes payable on each Payment Date
shall be paid to the Series A2 Noteholders 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 A2 Noteholders 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 A2
Notes reflecting such change, there shall be an increase in the cost to a Series A2
Noteholder of making or maintaining any investment in the Series A2 Note
or any interest therein or of agreeing to purchase or invest in the Series A2
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 A2 Noteholder 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 A2 Noteholder.  In determining such amount, such Series A2
Noteholder may use any reasonable averaging and attribution methods, consistent
with the averaging and attribution methods generally used by such Series A2
Noteholder 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 Series A2 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 A2 Noteholders as part of the Series A2
Increased Costs out of the Available Collections Amount on each Payment Date as
provided in Section 3.13 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 central bank or other
Governmental Authority reflecting such change after the Series Issuance
Date of the Series A2 Notes affects or would affect the amount of capital
required or expected to be maintained by any Series A2 Noteholder, and
such Series A2 Noteholder determines that the amount of such capital is
increased as a result of (i) the existence of the Series A2
Noteholder’s agreement to make or maintain an investment in the Series A2
Notes or any interest therein and other similar agreements or facilities, or (ii) the
existence of any agreement by Series A2 Noteholders to make or maintain an
investment in the Series A2 Notes or any interest therein or

 

14

 

to fund any such investment and any other commitments of the same type,
such Series A2 Noteholder 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 A2
Noteholder in light of such circumstances. 
In determining such amount, such Series A2 Noteholder may use any
reasonable averaging and attribution methods, consistent with the averaging and
attribution methods generally used by such Series A2 Noteholder 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 Series A2 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 A2 Noteholders as part of
the Series A2 Increased Costs out of the Available Collections Amount on
each Payment Date as provided in Section 3.13 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 Agreement, the
Series A2 Notes or the Indenture by WEST or the Indenture Trustee to or
for the benefit of a Series A2 Noteholder 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 A2
Noteholder hereunder, the amount so payable to such Series A2 Noteholder
shall be increased to the extent necessary to yield to such Series A2
Noteholder (after payment of all taxes, levies, imposts, duties, charges or
fees) the amount stated to be payable to such Series A2 Noteholder
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 A2 Noteholder, in each
case, as a result of a present or former connection (other than any connection
arising out of the transactions contemplated by this Agreement) between the
jurisdiction of the government or taxing authority imposing such tax and such Series A2
Noteholder; (ii) any taxes, levies, imposts, duties, charges or fees that
would not have been imposed but for the failure by such Series A2
Noteholder to provide and keep current any certification or other documentation
permitted by Applicable Law to be delivered by such Series A2 Noteholder
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 A2 Noteholder of the office through which the Series A2
Note or any interest hereunder is acquired, accounted for or booked as a result
of the sale, transfer or assignment by any Series A2 Noteholder 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 A2
Note or interest therein is acquired, accounted for or booked; (iv) taxes
measured by income, gross receipts, assets or

 

15

 

capital of any Series A2 Noteholder by the taxing authority of the
jurisdiction where such Series A2 Noteholder 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 A2 Noteholder under this
Agreement 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 A2
Noteholder as a result of payments not related to this Agreement; and (vi) any
withholding tax with respect to any Series A2 Noteholder that has not
provided the documentation referred to in Section 2.10(d) (all such
exclusions being hereinafter called “Excluded
Taxes”).  To the extent that
any Series A2 Noteholder 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 A2 Noteholder, such Series A2 Noteholder
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 A2 Noteholder; provided, however, that for
purposes of reimbursing WEST, such Series A2 Noteholder 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 A2
Noteholder as if such Series A2 Noteholder 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 A2
Noteholder agrees that, with respect to all Federal, state and local income
taxes, it will treat the Series A2 Note as indebtedness.

 

(c)                                  Any Section 2.10(a) Amounts
payable to a Series A2 Noteholder hereunder shall be included in the Series A2
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 A2 Noteholders as
part of the Series A2 Increased Costs out of the Available Collections
Amount on each Payment Date as provided in Section 3.13 of the Indenture
and Section 3.02 hereof.

 

(d)                                 Each Series A2
Noteholder 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
Agreement 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 Loan is made on a day other than a Payment Date, or (ii) any
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 A2 Noteholders against
any reasonable loss, cost or expense incurred by the Series A2
Noteholders, 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 A2
Noteholders to fund or maintain such Loan during such Interest Accrual
Period.  The Indenture

 

16

 

Trustee shall pay any amounts due under this Section 2.11 to the Series A
Noteholders as part of the Series A2 Increased Costs out of the Available
Collections Amount on each Payment Date as provided in Section 3.13 of the
Indenture and Section 3.02 hereof.

on Transfer.  On the Closing Date,
WEST shall sell the Series A2 Notes to the Series A2 Noteholders
pursuant to the Series A2 Note Purchase Agreement and deliver such Series A2
Notes in accordance herewith and therewith. 
Thereafter, no Series A2 Note may be sold, transferred or otherwise

Supplement and the Series A2 Note Purchase Agreement.  Except as provided herein and in the
Indenture, the Indenture Trustee shall have no obligations or duties with
respect to determining whether any transfers of the Series A2 Notes are
made in accordance with the Securities Act or any other law; provided that with respect to Definitive
Notes, the Indenture Trustee shall enforce such transfer restrictions in
accordance with the terms set forth in this Supplement.  Prior to the occurrence of a Conversion
Event, the Indenture Trustee shall not register any transfer of a Series A2
Note, in whole or in part, unless the transferee of such Series A2 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 A2
Note Purchase Agreement to make Loans in an amount equal to the excess of the
Maximum Principal Balance of the Series A2 Note being transferred at the
time of transfer over the Outstanding Principal Balance of such Series A2
Note at such time.

interpreted in accordance with, the laws of the State of New York without

first Payment Date with respect to the Series B2 Notes shall be on September 15,

Section 2.03                                Loans under the Series B2
Notes.  (a)  WEST shall have the
right, pursuant to this Supplement and the Series B2 Note Purchase
Agreement, to borrow Loans from the Series B2 Noteholders, and each Series B2
Noteholders has severally agreed, pursuant to the Series B2 Note Purchase
Agreement, to make Loans, in each case in proportion to, and up to the amounts
of, its respective Maximum Commitments of the Series B2 Noteholders, on
the Initial Closing Date and on any Business Day (a “Funding Date”) thereafter 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 B2 Note Purchase Agreement. 
Each such Loan shall increase the Outstanding Principal Balance of the Series B2
Notes held by such Series B2 Noteholder. 
The Indenture Trustee shall maintain a record of all Loans and
repayments made on the Series B2 Notes and absent manifest error such
records shall be conclusive.

Funding Request for Loans after the Initial Closing Date shall constitute a

Event or Early Amortization Event has occurred and is continuing, or would
result from the making of such Loan, as of the date of the Funding Request and (2) the
representations and warranties of WEST contained in the Series 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 use the proceeds of the Loans made on the Initial Closing Date for the
purposes described in the Offering Memorandum and shall use the proceeds of the
Loans made on each subsequent Funding Date for any or all of the following
purposes: (i) to acquire the Third Remaining Engine, (ii) 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 (iii) to
increase the Available Collections Amount on any Payment Date by depositing all
or a portion of the proceeds of a Loan in the Collections Account, provided that the use of any Loan to
increase the Available Collections Amount shall be subject to the Available
Collections Amount on such Payment Date being in an amount, calculated without
the proceeds of such Loan, sufficient to 

 

9

 

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 3.13 of the Indenture.

 

(d)                                 WEST
may elect to increase the aggregate Maximum Principal Balances of the Series B2
Notes and the aggregate Maximum Commitments of the Series B2 Noteholders
to an amount greater than $13,558,400 but not in excess of $21,428,521, subject
to the receipt of (i) the prior written consent of all of the Series B2
Noteholders and (ii) a Rating Agency Confirmation, provided that, as a condition of any such
increase, the Maximum Principal Balances of the Series A2 Notes and the
Maximum Commitments of the Series A2 Noteholders shall be increased by a
proportionate amount, such increase to be made as provided in the Series A2
Supplement and the Series A2 Note Purchase Agreement.  Any increase pursuant to the preceding
sentence shall be applied to increase the Maximum Principal Balances of the
individual Series B2 Notes and the Maximum Commitments of the Series B2
Noteholders proportionately to the Maximum Principal Balances of the Series B2
Notes held by the Series B2 Noteholders immediately prior to such
increase, and such increases shall be deemed to occur without any Series B2
Noteholder having to surrender its Series B2 Notes in exchange for a new Series B2
Note reflecting the increased Maximum Principal Balance.

 

(e)                                  WEST
may, on any Payment Date upon at least five Business Days’ notice to the Series B2
Noteholders, terminate in whole or reduce in part the aggregate Maximum
Commitments of the Series B2 Noteholders and the Maximum Principal
Balances of the Series B2 Notes in an aggregate amount not to exceed the
excess of such Maximum Principal Balances over the then aggregate Outstanding
Principal Balance of the Series B2 Notes; provided
that any partial reduction of the aggregate Maximum Commitments of the Series B2
Noteholders and the Maximum Principal Balances of the Series B2 Notes (i) shall
be applied pro rata to the individual Maximum Commitments of the Series B2
Noteholders and the Maximum Principal Balances of the Series 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 A2
Noteholders.  Each notice of reduction or
termination pursuant to this Section 2.03(e) shall be irrevocable,
and such reduction shall be deemed to occur without any Series B2
Noteholder having to surrender its Series B2 Notes in exchange for a new Series B2
Note reflecting the reduced Maximum Principal Balance.

 

(f)                                    WEST
may, on any Payment Date prior to the occurrence of a Conversion Event
terminate the agreements of the Series B2 Noteholders to make Loans and
repay the Outstanding Principal Balance of the Series B2 Notes for the
Redemption Price, upon (a) at least five (5) Business Days’ prior
written notice to each Series B2 Noteholder, 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 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 B2 Noteholder under this Agreement, the Supplement and the
Indenture and (c) the simultaneous termination of the commitments of the Series B1
Noteholders and the payment in full of all amounts owing with respect to the Series B1
Notes.

 

(g)                                 If
any Series B2 Noteholder shall default on its obligation to make a Loan on
any Funding Date, one or more of the other Series B2 Noteholders may elect
(but shall not be 

 

10

 

obligated) to make the Loan of the defaulting Series B2
Noteholder.  In such event, the Maximum
Principal Balance of the Series B2 Note held by the defaulting Series B2
Noteholder and the Maximum Commitment of the Series B2 Noteholder shall be
reduced by the amount of the Loan so made, and the Maximum Principal Balance of
the Series B2 Note held by the Series B2 Noteholder making such Loan
and the Maximum Commitment of such Series B2 Noteholder shall be increased
by the amount of such Loan.

 

(h)                                 Upon
the occurrence of a Conversion Event, (i) the right of WEST to borrow
under the Series B2 Notes shall terminate, (ii) Conversion Step-Up
Interest shall begin to accrue on the Outstanding Principal Balance of the Series B2
Notes as provided in Section 2.04(a), and (iii) the Outstanding
Principal Balance of the Series B2 Notes shall become payable as provided
in Section 2.05(a) and (b), provided,
however, that, if all of the Series B2 Noteholders elect to
waive the occurrence of any Conversion Event, such Conversion Event shall be
disregarded as long as such waiver is in effect; provided, further, that, if WEST subsequently cures an Early
Amortization Event, Event of Default or Servicer Termination Event that
resulted in a Conversion Event that was not so waived, WEST may request the Series B2
Noteholders to waive the original occurrence of such Conversion Event, Event of
Default or Servicer Termination Event and rescind and revoke the consequences
described in clause (i), (ii) and (iii) of this Section 2.04(h) occurring
as a result of such Conversion Event, which waiver, rescission and revocation
shall be effective only if Series B2 Noteholders representing 100% of the
Outstanding Principal Balance of the Series B2 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.

Commitment Fee shall accrue at the Series B2 Commitment Fee Rate on the
Unused Commitment of the Series B2 Noteholders during all or the portion
of each Interest Accrual Period from the Closing Date to (but excluding) the

The Series B2 Commitment Fee Amount 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 Series B2 Base Interest Amount, Series B2
Supplemental Interest Amount, Series B2 Conversion Step-Up Interest Amount
or Series B2 Commitment Fee on any Series B2 Note when due, (ii) any
Series B2 Increased Costs or (iii) any other amount becoming due
under this Supplement (other than payments of principal on the Series B2

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 Series B2 Additional Interest

amount permitted by Applicable Law.  If
at any time the Series B2 Interest Amount charged with respect to the Series B2
Notes exceeds the maximum rate permitted by Applicable Law, the rate of
interest to accrue pursuant to this Supplement and such Series 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 B2 Note below the maximum amount permitted by
Applicable Law until the total amount of interest accrued on such Series 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 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 B2
Noteholders 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 Series B2 Interest Amount, and (b) the amount of
interest accrued in accordance with the other provisions of this Supplement.

Notes out of the Series B Supplemental Principal Payment Amount, to the extent
and as provided in Sections 3.13 and 3.14(b) of the Indenture and in Section 3.02

Payment Date prior to the date on which a Conversion Event occurs, the Series B2
Notes shall be treated as Warehouse Notes for purposes 

 

12

 

of Section 3.14(b) of the Indenture and, on any Payment Date
on or after a Conversion Event, the Series B2 Notes shall be treated as
other than Warehouse Notes for such purposes.

 

(b)                                 (i) 
Within ten (10) Business Days after the occurrence of a Conversion Event

Conversion Event), WEST shall cause the Administrative Agent to prepare and
deliver to the Indenture Trustee and the Series B2 Noteholders a schedule of
the Scheduled Targeted Principal Balances for the Series B2 Notes
substantially in the form of Schedule 1 attached hereto, calculated using
the Outstanding Principal Balance of the Series B2 Notes as of the close
of business on the date on which the Conversion Event occurs.  The first Payment Date in the schedule shall
be on the first Payment Date after the date on which a Conversion Event
occurs.  If the Series B2
Noteholders subsequently waive the occurrence of Conversion Events as provided
in Section 2.03(f), the schedule delivered pursuant to this Section 2.05(b)(i) shall
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 B2
Noteholders, 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, the Scheduled Principal Payment

be payable to the Holders of the Series B2 Notes on each such Payment Date
from amounts deposited in the Series B2 Series Account on such
Payment Date as provided in Section 3.13 of the Indenture and Section 3.02

Amortization Event or an Event of Default is then continuing, the Outstanding
Principal Balance of the Series 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 3.13 of the Indenture and Section 3.02
of this Supplement.    The then
Outstanding Principal Balance of all Series B2 Notes shall be due and
payable on the earlier to occur of (i) the date on which the Series B2
Notes have been accelerated in accordance with the provisions of Section 4.02
of the Indenture and (ii) the Series B2 Final Maturity Date.

Balance of the Series B2 Notes on such Payment Date, in a minimum amount
of Two Hundred Fifty Thousand Dollars ($250,000), 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 B1 Notes shall be prepaid by a proportionate amount,
such prepayment to be made as provided in the Series B1 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 B2 Series Account or the Senior Restricted Cash
Account, provided that funds in such Accounts may be used to fund a 

 

13

 

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 whole or in part.

 

(d)                                 If
there is any Balance in the Engine Acquisition Account at the end of the
Delivery Period beginning on the Initial Closing Date, the portion thereof
allocated to the Series B2 Notes in accordance with Section 3.15(b) of
the Indenture shall be applied to the prepayment of the Series B2 Notes as
provided in Section 3.16 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 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 3.18 of the Indenture.

 

Section 2.06                                Series B2
Final Maturity Date.  The unpaid
principal amount of the Series 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 B2 Transaction Documents
shall be due and payable in full on the earlier to occur of (i) the date
on which the Series B2 Notes have been accelerated in accordance with the
provisions of Section 4.02 of the Indenture and (ii) the Series B2
Final Maturity Date.

 

Section 2.07                                Manner
of Payments.  All payments of
principal and interest on the Series B2 Notes payable on each Payment Date
shall be paid to the Series B2 Noteholders 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 B2 Noteholders 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 B2
Notes reflecting such change, there shall be an increase in the cost to a Series B2
Noteholder of making or maintaining any investment in the Series B2 Note
or any interest therein or of agreeing to purchase or invest in the Series 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 B2 Noteholder 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 B2 Noteholder.  In determining such amount, such Series B2
Noteholder may use any reasonable averaging and attribution methods, consistent
with the averaging and attribution methods generally used by such Series B2
Noteholder 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 Series B2 Increased Costs for the
Interest Accrual Period immediately succeeding the date on which such
certificate was delivered 

 

14

 

(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 B2 Noteholders as part of the Series B2
Increased Costs out of the Available Collections Amount on each Payment Date as
provided in Section 3.13 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 central bank or other
Governmental Authority reflecting such change after the Series Issuance
Date of the Series B2 Notes affects or would affect the amount of capital
required or expected to be maintained by any Series B2 Noteholder, and
such Series B2 Noteholder determines that the amount of such capital is
increased as a result of (i) the existence of the Series B2
Noteholder’s agreement to make or maintain an investment in the Series B2
Notes or any interest therein and other similar agreements or facilities, or (ii) the
existence of any agreement by Series B2 Noteholders to make or maintain an
investment in the Series B2 Notes or any interest therein or to fund any
such investment and any other commitments of the same type, such Series B2
Noteholder 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 B2
Noteholder in light of such circumstances. 
In determining such amount, such Series B2 Noteholder may use any
reasonable averaging and attribution methods, consistent with the averaging and
attribution methods generally used by such Series B2 Noteholder 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 Series B2 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 B2 Noteholders as part of
the Series B2 Increased Costs out of the Available Collections Amount on
each Payment Date as provided in Section 3.13 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 Agreement, the
Series B2 Notes or the Indenture by WEST or the Indenture Trustee to or
for the benefit of a Series B2 Noteholder 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, “Taxes”)
are required to be withheld from any amount payable to any Series B2
Noteholder hereunder, the amount so payable to such Series B2 Noteholder
shall be increased to the extent necessary to yield to such Series B2
Noteholder (after payment of all taxes, levies, imposts, duties, charges or
fees) the amount stated to be payable to such Series B2 Noteholder
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, 

 

15

 

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 B2 Noteholder, in each case, as a result of
a present or former connection (other than any connection arising out of the
transactions contemplated by this Agreement) between the jurisdiction of the
government or taxing authority imposing such tax and such Series B2
Noteholder; (ii) any taxes, levies, imposts, duties, charges or fees that
would not have been imposed but for the failure by such Series B2
Noteholder to provide and keep current any certification or other documentation
permitted by Applicable Law to be delivered by such Series B2 Noteholder
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 B2 Noteholder of the office through which the Series B2
Note or any interest hereunder is acquired, accounted for or booked as a result
of the sale, transfer or assignment by any Series B2 Noteholder 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 B2 Note or interest therein is acquired, accounted for or
booked; (iv) taxes measured by income, gross receipts, assets or capital
of any Series B2 Noteholder by the taxing authority of the jurisdiction
where such Series B2 Noteholder 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 B2 Noteholder under this Agreement 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 B2 Noteholder as a
result of payments not related to this Agreement; and (vi) any withholding
tax with respect to any Series B2 Noteholder that has not provided the
documentation referred to in Section 2.10(d) (all such exclusions
being hereinafter called “Excluded Taxes”).  To the extent that any Series B2
Noteholder 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 B2
Noteholder, such Series B2 Noteholder 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 B2
Noteholder; provided, however, that for purposes of reimbursing WEST, such Series B2
Noteholder 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 B2 Noteholder as if such Series B2 Noteholder
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 B2 Noteholder agrees that, with respect to all Federal,
state and local income taxes, it will treat the Series B2 Note as
indebtedness.

 

(c)                                  Any
Section 2.10(a) Amounts payable to a Series B2 Noteholder
hereunder shall be included in the Series B2 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 B2 Noteholders as part of the Series B2 Increased Costs
out of the Available Collections Amount on each Payment Date as provided in Section 3.13
of the Indenture and Section 3.02 hereof.

 

16

 

(d)                                 Each
Series B2 Noteholder 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 Agreement 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 Loan is made on a day other than a Payment Date, or (ii) any
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 B2 Noteholders against
any reasonable loss, cost or expense incurred by the Series B2
Noteholders, 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 B2
Noteholders to fund or maintain such Loan during such Interest Accrual
Period.  The Indenture Trustee shall pay
any amounts due under this Section 2.11 to the Series B Noteholders
as part of the Series B2 Increased Costs out of the Available Collections
Amount on each Payment Date as provided in Section 3.13 of the Indenture
and Section 3.02 hereof.

 

Section 2.12                                Restrictions
on Transfer.  On the Closing Date,
WEST shall sell the Series B2 Notes to the Series B2 Noteholders
pursuant to the Series B2 Note Purchase Agreement and deliver such Series B2
Notes in accordance herewith and therewith. 
Thereafter, no Series B2 Note may be sold, transferred or otherwise
disposed of except in compliance with the provisions of the Indenture, this
Supplement and the Series B2 Note Purchase Agreement.  Except as provided herein and in the
Indenture, the Indenture Trustee shall have no obligations or duties with
respect to determining whether any transfers of the Series B2 Notes are
made in accordance with the Securities Act or any other law; provided that with respect to Definitive
Notes, the Indenture Trustee shall enforce such transfer restrictions in
accordance with the terms set forth in this Supplement.  Prior to the occurrence of a Conversion
Event, the Indenture Trustee shall not register any transfer of a Series B2
Note, in whole or in part, unless the transferee of such Series 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 B2
Note Purchase Agreement to make Loans in an amount equal to the excess of the
Maximum Principal Balance of the Series B2 Note being transferred at the
time of transfer over the Outstanding Principal Balance of such Series B2
Note at such time.

 

Section 2.13                                Payment

Noteholders.

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 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 (as
amended, restated or otherwise modified from time to time, the “Indenture”) and
the Series B2 Supplement, dated as of August    , 2005
(as amended, restated or otherwise modified from time to time, the “Series 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 B2 Note on the dates and in
the amounts set forth in the Indenture and the Series B2 Supplement.  Capitalized terms not otherwise defined
herein will have the meaning set forth in the Indenture and the Series B2
Supplement.

 

Payment
of the principal of, interest on and Increased Costs for this Series 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 B2 Note and any
Increased Costs are payable at the times and in the amounts set forth in the
Indenture and the Series 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 B2
Note is one of the authorized notes identified in the title hereto and issued
in the aggregate Maximum Principal Balance of Thirteen Million Five Hundred
Fifty-Eight Thousand Four Hundred Dollars ($13,558,400) pursuant to the
Indenture and the Series B2 Supplement, provided that the aggregate
Maximum Principal Balance of the Series B2 Notes may be increased up to Twenty-One
Million Four Hundred Twenty-Eight Thousand Five Hundred Twenty-One Dollars ($21,428,521)
as provided in the Indenture and the Series B2 Supplement.

 

The Series 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 B2
Note is transferable as provided in the Indenture and the Series B2
Supplement, subject to certain limitations therein contained, only upon the
books for registration 

 

A-1

 

and transfer kept by the
Indenture Trustee, and only upon surrender of this Series 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 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 B2 Note unless the transferee meets
the requirements for an Eligible Transferee in the Series B2 Supplement
and agrees to make Loans up to an amount equal to the excess of the Maximum
Principal Balance of this Series B2 Note at the time of transfer over the
Outstanding Principal Balance of this Series 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 B2 Notes.

 

WEST,
the Indenture Trustee and any other agent of WEST may treat the person in whose
name this Series 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 B2
Notes are subject to Optional Redemption, at the times and subject to the
conditions set forth in the Indenture and the Series B2 Supplement.

 

If an
Event of Default of the Indenture shall occur and be continuing, the principal
of and accrued interest on this Series B2 Note may be declared to be due
and payable in the manner and with the effect provided in the Indenture and the
Series 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 B2 Note and
on all future holders of this Series B2 Note and of any Series B2
Note issued in lieu hereof whether or not notation of such consent is made upon
this Series B2 Note. Supplements and amendments to the Indenture and the Series B2
Supplement may be made only to the extent and in circumstances permitted by the
Indenture and the Series B2 Supplement.

 

The
Holder of this Series B2 Note shall have no right to enforce the
provisions of the Indenture and the Series 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 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 B2
Supplement; provided, however, that nothing contained in the Indenture and the Series 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 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 B2 Supplement.

 

A-2

 

The
purchaser of a Series B2 Note shall be deemed to represent and warrant to
the Initial Purchasers, WEST, the Indenture Trustee and the Servicer that
either (1) it is not acquiring the Series B2 Note with the assets of
a Benefit Plan; or (2) (a) the Series B2 Note is rated
investment grade or better and such person believes that the Offered Note is
properly treated as indebtedness without substantial equity features for
purposes of the Department of Labor Regulations Section 2510.101, and
agrees to so treat the Series B2 Note and (b) the acquisition and
holding of the Series B2 Note will not give rise to a nonexempt prohibited
transaction under Section 406 of ERISA or Section 4975 of the Code.

 

The indebtedness evidenced by the Series B2
Notes 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 B2 Note is
issued subject to such provisions. Each Holder of this Series B2 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 B2 Note is
subject to acceleration upon the occurrence and during the continuance of the
Events of Default specified in the Indenture. The Series B2 Noteholders
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 and principal on the Series A
Notes have been paid in full.

 

The Holder of this Series 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 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 3.13
and Article XI of the Indenture may not be amended or modified without the
consent of each Hedge Counterparty, each Noteholder of the subclass affected
thereby and each Noteholder 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 Class of Notes, on behalf
of the Holders of all of the Series B2 Notes, to waive compliance by the
Issuer 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 B2
Note and of any Series B2 Note issued upon the registration of transfer
of, in exchange or in lieu of or upon the refinancing of this Series B2
Note, whether or not notation of such consent or waiver is made upon this Series B2
Note.

 

A-3

 

This Series 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.

 

All
terms and provisions of the Indenture and the Series 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 B2 Supplement and the issuance of
this Series 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 B2
Note shall not be entitled to any benefit under the Indenture and the Series B2
Supplement, or be valid or obligatory for any purpose.

WITNESS WHEREOF, Willis Engine Securitization Trust has caused this Series B2
Note to be duly executed by its duly authorized representative, on this    day
