            2. Assignment of Servicing Agreements. The Seller agrees to sell,
and the Company agrees to purchase, the mortgage loans (the "Mortgage Loans"),
other than the Fixed Retained Yield with respect to the Mortgage Loans, listed

            3. Purchase Price; Purchase and Sale. The purchase price (the

            Upon payment of the Purchase Price, the Seller shall be deemed to
have transferred, assigned, set over and otherwise conveyed to the Company all
the right, title and interest of the Seller in and to the Mortgage Loans
including all interest and principal received or receivable by the Seller on or
with respect to the Mortgage Loans after the Cut-Off Date (and including
scheduled payments of principal and interest due after the Cut-Off Date but
received by the Seller on or before the Cut-Off Date and Principal Prepayments
received or applied on the Cut-Off Date, but not including payments of principal
and interest due on the Mortgage Loans on or before the Cut-Off Date), together
with all of the Seller's right, title and interest in and to the proceeds of any
related title, hazard, primary mortgage or other insurance policies, the
Seller's right to receive amounts, if any, payable on behalf of any Mortgagor
from the Subsidy Account relating to any Subsidy Loan, the Seller's right, title
and interest in and to the proceeds of the Letters of Credit, all of the
Seller's rights described in Section 2 above, and all other property and rights
described in the first paragraph of Section 2.01(a) of the Pooling and Servicing
Agreement. The Company hereby directs the Seller, and the Seller hereby agrees,
to deliver to the Trustee or Custodian on behalf of the Trustee, all documents,
instruments and agreements required to be delivered by the Company to the
Trustee under the Pooling and Servicing Agreement; including, without
limitation, the documents required to be delivered under Section 2.01(a) of the
Pooling and Servicing Agreement; and upon the occurrence of a Document Transfer
Event, the documents required to be delivered under Section 2.01(b). The Seller
further agrees to deliver such other documents, instruments and agreements as
the Company or the Trustee shall reasonably request.

            4. Representations and Warranties; Covenants. The Seller hereby
represents and warrants to the Company that (i) the Company's representations
and warranties to the Trustee pursuant to Section 2.03(b) of the Pooling and
Servicing Agreement are true and correct, as of the date thereof, and (ii)
Seller has not dealt with any broker, investment banker, agent or other person
(other than the Company and Credit Suisse Securities (USA) LLC) who may be
entitled to any commission or compensation in connection with the sale of the
Mortgage Loans. The Seller hereby agrees to cure any breach of such
representations and warranties in accordance with the terms of the Pooling and
Servicing Agreement.

            The Seller hereby agrees to continue to pay on behalf of the Company
and its successors and assignees, promptly as they become due, any lender-paid
primary mortgage insurance premiums ("LPMI Premiums") with respect to any
lender-paid primary mortgage insurance policy (an "LPMI Policy") on each
Mortgage Loan so insured as of the Cut-Off Date, until such Mortgage Loan has
been paid in full or otherwise liquidated; provided, however, that the foregoing
obligation of the Seller shall terminate with respect to all such Mortgage Loans
in the event that either (i) another entity acceptable to the insurers of such
LPMI Policies (the "LPMI Insurers") and the rating agencies rating the
Certificates undertakes to pay such LPMI Premiums, or (ii) the Seller pays
one-time premiums to such LPMI Insurers such that all outstanding LPMI Policies
will remain in force until the related Mortgage Loans have been paid in full or
otherwise liquidated, without the requirement of any further premium payments.

            5. Repurchase or Substitution. (a) The Seller hereby agrees to
repurchase any Mortgage Loan (i) for which any document is not delivered, as
provided in paragraph 3 above, (ii) which is found by the Trustee or the
Custodian to be defective in any material respect, as provided in the Pooling
and Servicing Agreement, or (iii) which is discovered at any time not to be in
conformance with the representations and warranties referred to in paragraph 4
above and which document relating thereto the Seller does not deliver or which
defect or breach the Seller does not cure (as provided in paragraph 4 above)
within 60 days after the date of notice thereof from the Trustee or the Company,
at a price equal to the Repurchase Price. In addition, the Seller hereby agrees
to reimburse the Company for any Reimbursement Amount. Alternatively, the Seller
hereby agrees, if so requested by the Company to substitute for any such
Mortgage Loan, a new mortgage loan having characteristics such that the
representations and warranties referred to in paragraph 4 above would not have
been incorrect (except for representations and warranties as to the correctness
of the Mortgage Loan Schedule) had such substitute mortgage loan originally been
a Mortgage Loan. The Seller further agrees that a substituted mortgage loan will
have (i) an unpaid principal balance no greater than the Scheduled Principal
Balance of the Mortgage Loan for which it is substituted (after giving effect to
the scheduled principal payment due in the month of substitution on the Mortgage
Loan for which such mortgage loan is substituted) and (ii) a Net Mortgage
Interest Rate equal to and a Loan-to-Value Ratio no greater than that of the
Mortgage Loan for which it is substituted. The Seller shall remit to the
Company, in cash, the difference between the unpaid principal balance of the
Mortgage Loan to be substituted and the unpaid principal balance of the
substitute mortgage loan.

            (b) In the event that the Seller has a right against the originator
or former owner of a Mortgage Loan (the "Prior Holder") for breach of a
representation or warranty regarding the characteristics of such Mortgage Loan
made by the Prior Holder, the Seller may request the Company to repurchase the
Mortgage Loan from the Trust Estate pursuant to Section 3.08 of the Pooling and
Servicing Agreement and the Seller agrees that at the time of the repurchase by
the Company, the Seller will repurchase the Mortgage Loan from the Company at a
price equal to the Repurchase Price.

            At the time of any such repurchase by the Seller, the Seller agrees
either to promptly (i) liquidate such Mortgage Loan, to the extent that the
Seller's rights in respect of the Prior Holder consist of a claim for indemnity
or (ii) transfer such Mortgage Loan to the Prior Holder at a price not less than
that paid by the Seller to the Company.

            6. Underwriting. The Seller hereby agrees to furnish any and all
information, documents, certificates, letters or opinions with respect to the
Mortgage Loans, reasonably requested by the Company in order to perform any of
its obligations or satisfy any of the conditions on its part to be performed or
satisfied pursuant to the Underwriting Agreement or the Purchase Agreement at or
prior to the Closing Date.

            7. Costs. The Company shall pay all expenses incidental to the
performance of its obligations under the Underwriting Agreement and the Purchase
Agreement, including without limitation (i) any recording fees or fees for title
policy endorsements and continuations, (ii) the expenses of preparing, printing
and reproducing the Prospectus, the Prospectus Supplement, the Underwriting
Agreement, the Private Placement Memorandum, the Purchase Agreement, the Pooling
and Servicing Agreement and the Certificates and (iii) the cost of delivering
the Certificates to the offices of Credit Suisse Securities (USA) LLC insured to
the satisfaction of Credit Suisse Securities (USA) LLC.

            8. Servicing. (a) The Seller hereby represents to the Company that
the Mortgage Loans are serviced by the Servicers. The Seller has delivered
copies of each Servicing Agreement to the Company, though omitting schedules of
mortgage loans which are serviced thereunder, but which are not being sold in
this transaction.

            (b) With respect to each Mortgage Loan, the Servicing Fee Rate and
the Master Servicing Fee Rate (which is in addition to the Servicing Fee Rate)
shall be as set forth on the Mortgage Loan Schedule.

            (c) On the Closing Date, the Seller shall assign to the Company its
interest with respect to the Mortgage Loans in, to and under each Servicing
Agreement.

            9. Notices. All demands, notices and communications hereunder shall
be in writing, shall be effective only upon receipt and shall, if sent to the
Company, be addressed to it at Wells Fargo Asset Securities Corporation, 7430
New Technology Way, Frederick, Maryland 21703, Attn: Vice President, Structured
Finance, or, if sent to the Seller, be addressed to it at Wells Fargo Bank,
N.A., 7430 New Technology Way, Frederick, Maryland, 21703, Attn: Vice President,
Structured Finance.

            10. Trustee Beneficiary. The representations, warranties and
agreements made by the Seller in this Agreement are made for the benefit of, and
may be enforced by, the Trustee and the holders of Certificates to the same
extent that the Trustee and the holders of Certificates, respectively, have
rights against the Company under the Pooling and Servicing Agreement in respect
of representations, warranties and agreements made by the Company therein.

            11. Recharacterization. The parties hereto intend the conveyance by
the Seller to the Company of all of its right, title and interest in and to the
Mortgage Loans pursuant to this Agreement to constitute a purchase and sale and
not a loan. Notwithstanding the foregoing, to the extent that such conveyance is
held not to constitute a sale under applicable law, it is intended that this
Agreement shall constitute a security agreement under applicable law and that
the Seller shall be deemed to have granted to the Company a first priority
security interest in all of the Seller's right, title and interest in and to the
Mortgage Loans.

            12. Miscellaneous. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York. Neither this Agreement nor
any term hereof may be changed, waived, discharged or terminated except by a
writing signed by the party against whom enforcement of such change, waiver,
discharge or termination is sought. This Agreement may not be changed in any
manner which would have a material adverse effect on holders of Certificates
without the prior written consent of the Trustee. The Trustee shall be protected
in consenting to any such change to the same extent provided in Article VIII of
the Pooling and Servicing Agreement. This Agreement may be signed in any number
of counterparts, each of which shall be deemed an original, which taken together
shall constitute one and the same instrument. This Agreement shall bind and
inure to the benefit of and be enforceable by the Company and the Seller and
their respective successors and assigns.

      IN WITNESS WHEREOF, the Company and the Seller have caused this Agreement
to be duly executed by their respective officers as of the day and year first
above written.

                                MASTER AGREEMENT

                            dated as of July 28, 2006

Credit Suisse International      and    Wells Fargo Bank, N.A., not in its
                                        individual capacity, but solely as
        ("Party A")                      Master Servicer, on behalf of the
                                            Wells Fargo Mortgage Backed
                                        Securities 2006-10 Trust ("Party B")

have entered and/or anticipate entering into one or more transactions (each a
"Transaction") that are or will be governed by this Master Agreement, which
includes the schedule (the "Schedule"), and the documents and other confirming
evidence (each a "Confirmation") exchanged between the parties confirming those
Transactions.

Accordingly, the parties agree as follows:--

1.    Interpretation

(a) Definitions. The terms defined in Section 14 and in the Schedule will have
the meanings therein specified for the purpose of this Master Agreement.

(b) Inconsistency. In the event of any inconsistency between the provisions of
the Schedule and the other provisions of this Master Agreement, the Schedule
will prevail. In the event of any inconsistency between the provisions of any
Confirmation and this Master Agreement (including the Schedule), such
Confirmation will prevail for the purpose of the relevant Transaction.

(c) Single Agreement. All Transactions are entered into in reliance on the fact
that this Master Agreement and all Confirmations form a single agreement between
the parties (collectively referred to as this "Agreement"), and the parties
would not otherwise enter into any Transactions.

2.    Obligations

(a) General Conditions.

      (i) Each party will make each payment or delivery specified in each
      Confirmation to be made by it, subject to the other provisions of this
      Agreement.

      (ii) Payments under this Agreement will be made on the due date for value
      on that date in the place of the account specified in the relevant
      Confirmation or otherwise pursuant to this Agreement, in freely
      transferable funds and in the manner customary for payments in the
      required currency. Where settlement is by delivery (that is, other than by
      payment), such delivery will be made for receipt on the due date in the
      manner customary for the relevant obligation unless otherwise specified in
      the relevant Confirmation or elsewhere in this Agreement.

      (iii) Each obligation of each party under Section 2(a)(i) is subject to
      (1) the condition precedent that no Event of Default or Potential Event of
      Default with respect to the other party has occurred and is continuing,
      (2) the condition precedent that no Early Termination Date in respect of
      the relevant Transaction has occurred or been effectively designated and
      (3) each other applicable condition precedent specified in this Agreement.

(b) Change of Account. Either party may change its account for receiving a
payment or delivery by giving notice to the other party at least five Local
Business Days prior to the scheduled date for the payment or delivery to which
such change applies unless such other party gives timely notice of a reasonable
objection to such change.

(c) Netting. If on any date amounts would otherwise be payable:--

      (i)   in the same currency; and

      (ii)  in respect of the same Transaction,

by each party to the other, then, on such date, each party's obligation to make
payment of any such amount will be automatically satisfied and discharged and,
if the aggregate amount that would otherwise have been payable by one party
exceeds the aggregate amount that would otherwise have been payable by the other
party, replaced by an obligation upon the party by whom the larger aggregate
amount would have been payable to pay to the other party the excess of the
larger aggregate amount over the smaller aggregate amount.

The parties may elect in respect of two or more Transactions that a net amount
will be determined in respect of all amounts payable on the same date in the
same currency in respect of such Transactions, regardless of whether such
amounts are payable in respect of the same Transaction. The election may be made
in the Schedule or a Confirmation by specifying that subparagraph (ii) above
will not apply to the Transactions identified as being subject to the election,
together with the starting date (in which case subparagraph (ii) above will not,
or will cease to, apply to such Transactions from such date). This election may
be made separately for different groups of Transactions and will apply
separately to each pairing of Offices through which the parties make and receive
payments or deliveries.

(d) Deduction or Withholding for Tax.

      (i) Gross-Up. All payments under this Agreement will be made without any
      deduction or withholding for or on account of any Tax unless such
      deduction or withholding is required by any applicable law, as modified by
      the practice of any relevant governmental revenue authority, then in
      effect. If a party is so required to deduct or withhold, then that party
      ("X") will:--

            (1) promptly notify the other party ("Y") of such requirement;

            (2) pay to the relevant authorities the full amount required to be
            deducted or withheld (including the full amount required to be
            deducted or withheld from any additional amount paid by X to Y under
            this Section 2(d)) promptly upon the earlier of determining that
            such deduction or withholding is required or receiving notice that
            such amount has been assessed against Y;

            (3) promptly forward to Y an official receipt (or a certified copy),
            or other documentation reasonably acceptable to Y, evidencing such
            payment to such authorities; and

            (4) if such Tax is an Indemnifiable Tax, pay to Y, in addition to
            the payment to which Y is otherwise entitled under this Agreement,
            such additional amount as is necessary to ensure that the net amount
            actually received by Y (free and clear of Indemnifiable Taxes,
            whether assessed against X or Y) will equal the full amount Y would
            have received had no such deduction or withholding been required.
            However, X will not be required to pay any additional amount to Y to
            the extent that it would not be required to be paid but for:--

                  (A) the failure by Y to comply with or perform any agreement
                  contained in Section 4(a)(i), 4(a)(iii) or 4(d); or

                  (B) the failure of a representation made by Y pursuant to
                  Section 3(f) to be accurate and true unless such failure would
                  not have occurred but for (I) any action taken by a taxing
                  authority, or brought in a court of competent jurisdiction, on
                  or after the date on which a Transaction is entered into
                  (regardless of whether such action is taken or brought with
                  respect to a party to this Agreement) or (II) a Change in Tax
                  Law.

      (ii)  Liability. If:--

            (1) X is required by any applicable law, as modified by the practice
            of any relevant governmental revenue authority, to make any
            deduction or withholding in respect of which X would not be required
            to pay an additional amount to Y under Section 2(d)(i)(4);

            (2) X does not so deduct or withhold; and

            (3) a liability resulting from such Tax is assessed directly against
            X,

      then, except to the extent Y has satisfied or then satisfies the liability
      resulting from such Tax, Y will promptly pay to X the amount of such
      liability (including any related liability for interest, but including any
      related liability for penalties only if Y has failed to comply with or
      perform any agreement contained in Section 4(a)(i), 4(a)(iii) or 4(d)).

(e) Default Interest; Other Amounts. Prior to the occurrence or effective
designation of an Early Termination Date in respect of the relevant Transaction,
a party that defaults in the performance of any payment obligation will, to the
extent permitted by law and subject to Section 6(c), be required to pay interest
(before as well as after judgment) on the overdue amount to the other party on
demand in the same currency as such overdue amount, for the period from (and
including) the original due date for payment to (but excluding) the date of
actual payment, at the Default Rate. Such interest will be calculated on the
basis of daily compounding and the actual number of days elapsed. If, prior to
the occurrence or effective designation of an Early Termination Date in respect
of the relevant Transaction, a party defaults in the performance of any
obligation required to be settled by delivery, it will compensate the other
party on demand if and to the extent provided for in the relevant Confirmation
or elsewhere in this Agreement.

3. Representations

Each party represents to the other party (which representations will be deemed
to be repeated by each party on each date on which a Transaction is entered into
and, in the case of the representations in Section 3(f), at all times until the
termination of this Agreement) that:--

(a) Basic Representations.

      action to authorise such execution, delivery and performance;

      (iii) No Violation or Conflict. Such execution, delivery and performance
      do not violate or conflict with any law applicable to it, any provision of

      Credit Support Document to which it is a party constitute its legal, valid
      and binding obligations, enforceable in accordance with their respective
      terms (subject to applicable bankruptcy, reorganisation, insolvency,
      moratorium or similar laws affecting creditors' rights generally and
      subject, as to enforceability, to equitable principles of general
      application (regardless of whether enforcement is sought in a proceeding
      in equity or at law)).

(b) Absence of Certain Events. No Event of Default or Potential Event of Default
or, to its knowledge, Termination Event with respect to it has occurred and is
continuing and no such event or circumstance would occur as a result of its

      Agreement or any applicable Credit Support Document without any deduction
      or withholding for or on account of any Tax or with such deduction or
      withholding at a reduced rate (so long as the completion, execution or
      submission of such form or document would not materially prejudice the
      legal or commercial position of the party in receipt of such demand), with
      any such form or document to be accurate and completed in a manner
      reasonably satisfactory to such other party and to be executed and to be
      delivered with any reasonably required certification,

Support Document to which it is a party and will use all reasonable efforts to
obtain any that may become necessary in the future.

(c) Comply with Laws. It will comply in all material respects with all
applicable laws and orders to which it may be subject if failure so to comply
would materially impair its ability to perform its obligations under this
Agreement or any Credit Support Document to which it is a party.

(d) Tax Agreement. It will give notice of any failure of a representation made
by it under Section 3(f) to be accurate and true promptly upon learning of such
failure.

(e) Payment of Stamp Tax. Subject to Section 11, it will pay any Stamp Tax
levied or imposed upon it or in respect of its execution or performance of this
Agreement by a jurisdiction in which it is incorporated, organised, managed and
controlled, or considered to have its seat, or in which a branch or office
through which it is acting for the purpose of this Agreement is located ("Stamp
Tax Jurisdiction") and will indemnify the other party against any Stamp Tax
levied or imposed upon the other party or in respect of the other party's
execution or performance of this Agreement by any such Stamp Tax Jurisdiction
which is not also a Stamp Tax Jurisdiction with respect to the other party.

5. Events of Default and Termination Events

(a) Events of Default. The occurrence at any time with respect to a party or, if
applicable, any Credit Support Provider of such party or any Specified Entity of
such party of any of the following events constitutes an event of default (an
"Event of Default") with respect to such party:--

      (i) Failure to Pay or Deliver. Failure by the party to make, when due, any
      payment under this Agreement or delivery under Section 2(a)(i) or 2(e)
      required to be made by it if such failure is not remedied on or before the
      third Local Business Day after notice of such failure is given to the
      party;

      (ii) Breach of Agreement. Failure by the party to comply with or perform
      any agreement or obligation (other than an obligation to make any payment
      under this Agreement or delivery under Section 2(a)(i) or 2(e) or to give
      notice of a Termination Event or any agreement or obligation under Section
      4(a)(i), 4(a)(iii) or 4(d)) to be complied with or performed by the party
      in accordance with this Agreement if such failure is not remedied on or
      before the thirtieth day after notice of such failure is given to the
      party;

      (iii) Credit Support Default.

            (1) Failure by the party or any Credit Support Provider of such
            party to comply with or perform any agreement or obligation to be
            complied with or performed by it in accordance with any Credit
            Support Document if such failure is continuing after any applicable
            grace period has elapsed;

            (2) the expiration or termination of such Credit Support Document or
            the failing or ceasing of such Credit Support Document to be in full
            force and effect for the purpose of this Agreement (in either case
            other than in accordance with its terms) prior to the satisfaction
            of all obligations of such party under each Transaction to which
            such Credit Support Document relates without the written consent of
            the other party; or

            (3) the party or such Credit Support Provider disaffirms, disclaims,
            repudiates or rejects, in whole or in part, or challenges the
            validity of, such Credit Support Document;

      (iv) Misrepresentation. A representation (other than a representation
      under Section 3(e) or (f)) made or repeated or deemed to have been made or
      repeated by the party or any Credit Support Provider of such party in this
      Agreement or any Credit Support Document proves to have been incorrect or
      misleading in any material respect when made or repeated or deemed to have
      been made or repeated;

      (v) Default under Specified Transaction. The party, any Credit Support
      Provider of such party or any applicable Specified Entity of such party
      (1) defaults under a Specified Transaction and, after giving effect to any
      applicable notice requirement or grace period, there occurs a liquidation
      of, an acceleration of obligations under, or an early termination of, that
      Specified Transaction, (2) defaults, after giving effect to any applicable
      notice requirement or grace period, in making any payment or delivery due
      on the last payment, delivery or exchange date of, or any payment on early
      termination of, a Specified Transaction (or such default continues for at
      least three Local Business Days if there is no applicable notice
      requirement or grace period) or (3) disaffirms, disclaims, repudiates or
      rejects, in whole or in part, a Specified Transaction (or such action is
      taken by any person or entity appointed or empowered to operate it or act
      on its behalf);

      (vi) Cross Default. If "Cross Default" is specified in the Schedule as
      applying to the party, the occurrence or existence of (1) a default, event
      of default or other similar condition or event (however described) in
      respect of such party, any Credit Support Provider of such party or any
      applicable Specified Entity of such party under one or more agreements or
      instruments relating to Specified Indebtedness of any of them
      (individually or collectively) in an aggregate amount of not less than the
      applicable Threshold Amount (as specified in the Schedule) which has
      resulted in such Specified Indebtedness becoming, or becoming capable at
      such time of being declared, due and payable under such agreements or
      instruments, before it would otherwise have been due and payable or (2) a
      default by such party, such Credit Support Provider or such Specified
      Entity (individually or collectively) in making one or more payments on
      the due date thereof in an aggregate amount of not less than the
      applicable Threshold Amount under such agreements or instruments (after
      giving effect to any applicable notice requirement or grace period);

      (vii) Bankruptcy. The party, any Credit Support Provider of such party or
      any applicable Specified Entity of such party:--

            (1) is dissolved (other than pursuant to a consolidation,
            amalgamation or merger); (2) becomes insolvent or is unable to pay
            its debts or fails or admits in writing its inability generally to
            pay its debts as they become due; (3) makes a general assignment,
            arrangement or composition with or for the benefit of its creditors;
            (4) institutes or has instituted against it a proceeding seeking a
            judgment of insolvency or bankruptcy or any other relief under any
            bankruptcy or insolvency law or other similar law affecting
            creditors' rights, or a petition is presented for its winding-up or
            liquidation, and, in the case of any such proceeding or petition
            instituted or presented against it, such proceeding or petition (A)
            results in a judgment of insolvency or bankruptcy or the entry of an
            order for relief or the making of an order for its winding-up or
            liquidation or (B) is not dismissed, discharged, stayed or
            restrained in each case within 30 days of the institution or
            presentation thereof; (5) has a resolution passed for its
            winding-up, official management or liquidation (other than pursuant
            to a consolidation, amalgamation or merger); (6) seeks or becomes
            subject to the appointment of an administrator, provisional
            liquidator, conservator, receiver, trustee, custodian or other
            similar official for it or for all or substantially all its assets;
            (7) has a secured party take possession of all or substantially all
            its assets or has a distress, execution, attachment, sequestration
            or other legal process levied, enforced or sued on or against all or
            substantially all its assets and such secured party maintains
            possession, or any such process is not dismissed, discharged, stayed
            or restrained, in each case within 30 days thereafter; (8) causes or
            is subject to any event with respect to it which, under the
            applicable laws of any jurisdiction, has an analogous effect to any
            of the events specified in clauses (1) to (7) (inclusive); or (9)
            takes any action in furtherance of, or indicating its consent to,
            approval of, or acquiescence in, any of the foregoing acts; or

      (viii) Merger Without Assumption. The party or any Credit Support Provider
      of such party consolidates or amalgamates with, or merges with or into, or
      transfers all or substantially all its assets to, another entity and, at
      the time of such consolidation, amalgamation, merger or transfer:--

            (1) the resulting, surviving or transferee entity fails to assume
            all the obligations of such party or such Credit Support Provider
            under this Agreement or any Credit Support Document to which it or
            its predecessor was a party by operation of law or pursuant to an
            agreement reasonably satisfactory to the other party to this
            Agreement; or

            (2) the benefits of any Credit Support Document fail to extend
            (without the consent of the other party) to the performance by such
            resulting, surviving or transferee entity of its obligations under
            this Agreement.

(b) Termination Events. The occurrence at any time with respect to a party or,
if applicable, any Credit Support Provider of such party or any Specified Entity
of such party of any event specified below constitutes an Illegality if the
event is specified in (i) below, a Tax Event if the event is specified in (ii)
below or a Tax Event Upon Merger if the event is specified in (iii) below, and,
if specified to be applicable, a Credit Event

Upon Merger if the event is specified pursuant to (iv) below or an Additional
Termination Event if the event is specified pursuant to (v) below:--

      (i) Illegality. Due to the adoption of, or any change in, any applicable
      law after the date on which a Transaction is entered into, or due to the
      promulgation of, or any change in, the interpretation by any court,
      tribunal or regulatory authority with competent jurisdiction of any
      applicable law after such date, it becomes unlawful (other than as a
      result of a breach by the party of Section 4(b)) for such party (which
      will be the Affected Party):--

            (1) to perform any absolute or contingent obligation to make a
            payment or delivery or to receive a payment or delivery in respect
            of such Transaction or to comply with any other material provision
            of this Agreement relating to such Transaction; or

            (2) to perform, or for any Credit Support Provider of such party to
            perform, any contingent or other obligation which the party (or such
            Credit Support Provider) has under any Credit Support Document
            relating to such Transaction;

      (ii) Tax Event. Due to (x) any action taken by a taxing authority, or
      brought in a court of competent jurisdiction, on or after the date on
      which a Transaction is entered into (regardless of whether such action is
      taken or brought with respect to a party to this Agreement) or (y) a
      Change in Tax Law, the party (which will be the Affected Party) will, or
      there is a substantial likelihood that it will, on the next succeeding
      Scheduled Payment Date (1) be required to pay to the other party an
      additional amount in respect of an Indemnifiable Tax under Section
      2(d)(i)(4) (except in respect of interest under Section 2(e), 6(d)(ii) or
      6(e)) or (2) receive a payment from which an amount is required to be
      deducted or withheld for or on account of a Tax (except in respect of
      interest under Section 2(e), 6(d)(ii) or 6(e)) and no additional amount is
      required to be paid in respect of such Tax under Section 2(d)(i)(4) (other
      than by reason of Section 2(d)(i)(4)(A) or (B));

      (iii) Tax Event Upon Merger. The party (the "Burdened Party") on the next
      succeeding Scheduled Payment Date will either (1) be required to pay an
      additional amount in respect of an Indemnifiable Tax under Section
      2(d)(i)(4) (except in respect of interest under Section 2(e), 6(d)(ii) or
      6(e)) or (2) receive a payment from which an amount has been deducted or
      withheld for or on account of any Indemnifiable Tax in respect of which
      the other party is not required to pay an additional amount (other than by
      reason of Section 2(d)(i)(4)(A) or (B)), in either case as a result of a
      party consolidating or amalgamating with, or merging with or into, or
      transferring all or substantially all its assets to, another entity (which
      will be the Affected Party) where such action does not constitute an event
      described in Section 5(a)(viii);

      (iv) Credit Event Upon Merger. If "Credit Event Upon Merger" is specified
      in the Schedule as applying to the party, such party ("X"), any Credit
      Support Provider of X or any applicable Specified Entity of X consolidates
      or amalgamates with, or merges with or into, or transfers all or
      substantially all its assets to, another entity and such action does not
      constitute an event described in Section 5(a)(viii) but the
      creditworthiness of the resulting, surviving or transferee entity is
      materially weaker than that of X, such Credit Support Provider or such
      Specified Entity, as the case may be, immediately prior to such action
      (and, in such event, X or its successor or transferee, as appropriate,
      will be the Affected Party); or

      (v) Additional Termination Event. If any "Additional Termination Event" is
      specified in the Schedule or any Confirmation as applying, the occurrence
      of such event (and, in such event, the Affected Party or Affected Parties
      shall be as specified for such Additional Termination Event in the
      Schedule or such Confirmation).

(c) Event of Default and Illegality. If an event or circumstance which would
otherwise constitute or give rise to an Event of Default also constitutes an
Illegality, it will be treated as an Illegality and will not constitute an Event
of Default.

6. Early Termination

(a) Right to Terminate Following Event of Default. If at any time an Event of
Default with respect to a party (the "Defaulting Party") has occurred and is
then continuing, the other party (the "Non-defaulting Party") may, by not more
than 20 days notice to the Defaulting Party specifying the relevant Event of
Default, designate a day not earlier than the day such notice is effective as an
Early Termination Date in respect of all outstanding Transactions. If, however,
"Automatic Early Termination" is specified in the Schedule as applying to a
party, then an Early Termination Date in respect of all outstanding Transactions
will occur immediately upon the occurrence with respect to such party of an
Event of Default specified in Section 5(a)(vii)(l), (3), (5), (6) or, to the
extent analogous thereto, (8), and as of the time immediately preceding the
institution of the relevant proceeding or the presentation of the relevant
petition upon the occurrence with respect to such party of an Event of Default
specified in Section 5(a)(vii)(4) or, to the extent analogous thereto, (8).

(b) Right to Terminate Following Termination Event.

      (i) Notice. If a Termination Event occurs, an Affected Party will,
      promptly upon becoming aware of it, notify the other party, specifying the
      nature of that Termination Event and each Affected Transaction and will
      also give such other information about that Termination Event as the other
      party may reasonably require.

      (ii) Transfer to Avoid Termination Event. If either an Illegality under
      Section 5(b)(i)(l) or a Tax Event occurs and there is only one Affected
      Party, or if a Tax Event Upon Merger occurs and the Burdened Party is the
      Affected Party, the Affected Party will, as a condition to its right to
      designate an Early Termination Date under Section 6(b)(iv), use all
      reasonable efforts (which will not require such party to incur a loss,
      excluding immaterial, incidental expenses) to transfer within 20 days
      after it gives notice under Section 6(b)(i) all its rights and obligations
      under this Agreement in respect of the Affected Transactions to another of
      its Offices or Affiliates so that such Termination Event ceases to exist.

      If the Affected Party is not able to make such a transfer it will give
      notice to the other party to that effect within such 20 day period,
      whereupon the other party may effect such a transfer within 30 days after
      the notice is given under Section 6(b)(i).

      Any such transfer by a party under this Section 6(b)(ii) will be subject
      to and conditional upon the prior written consent of the other party,
      which consent will not be withheld if such other party's policies in
      effect at such time would permit it to enter into transactions with the
      transferee on the terms proposed.

      (iii) Two Affected Parties. If an Illegality under Section 5(b)(i)( 1) or
      a Tax Event occurs and there are two Affected Parties, each party will use
      all reasonable efforts to reach agreement within 30 days after notice
      thereof is given under Section 6(b)(i) on action to avoid that Termination
      Event.

      (iv) Right to Terminate. If:--

            (1) a transfer under Section 6(b)(ii) or an agreement under Section
            6(b)(iii), as the case may be, has not been effected with respect to
            all Affected Transactions within 30 days after an Affected Party
            gives notice under Section 6(b)(i); or

            (2) an Illegality under Section 5(b)(i)(2), a Credit Event Upon
            Merger or an Additional Termination Event occurs, or a Tax Event
            Upon Merger occurs and the Burdened Party is not the Affected Party,

      either party in the case of an Illegality, the Burdened Party in the case
      of a Tax Event Upon Merger, any Affected Party in the case of a Tax Event
      or an Additional Termination Event if there is more than one Affected
      Party, or the party which is not the Affected Party in the case of a
      Credit Event Upon Merger or an Additional Termination Event if there is
      only one Affected Party may, by not more than 20 days notice to the other
      party and provided that the relevant Termination Event is then continuing,
      designate a day not earlier than the day such notice is effective as an
      Early Termination Date in respect of all Affected Transactions.

(c) Effect of Designation.

      (i) If notice designating an Early Termination Date is given under Section
      6(a) or (b), the Early Termination Date will occur on the date so
      designated, whether or not the relevant Event of Default or Termination
      Event is then continuing.

      (ii) Upon the occurrence or effective designation of an Early Termination
      Date, no further payments or deliveries under Section 2(a)(i) or 2(e) in
      respect of the Terminated Transactions will be required to be made, but
      without prejudice to the other provisions of this Agreement. The amount,
      if any, payable in respect of an Early Termination Date shall be
      determined pursuant to Section 6(e).

(d) Calculations.

      (i) Statement. On or as soon as reasonably practicable following the
      occurrence of an Early Termination Date, each party will make the
      calculations on its part, if any, contemplated by Section 6(e) and will
      provide to the other party a statement (1) showing, in reasonable detail,
      such calculations (including all relevant quotations and specifying any
      amount payable under Section 6(e)) and (2) giving details of the relevant
      account to which any amount payable to it is to be paid. In the absence of
      written confirmation from the source of a quotation obtained in
      determining a Market Quotation, the records of the party obtaining such
      quotation will be conclusive evidence of the existence and accuracy of
      such quotation.

      (ii) Payment Date. An amount calculated as being due in respect of any
      Early Termination Date under Section 6(e) will be payable on the day that
      notice of the amount payable is effective (in the case of an Early
      Termination Date which is designated or occurs as a result of an Event of
      Default) and on the day which is two Local Business Days after the day on
      which notice of the amount payable is effective (in the case of an Early
      Termination Date which is designated as a result of a Termination Event).
      Such amount will be paid together with (to the extent permitted under
      applicable law) interest thereon (before as well as after judgment) in the
      Termination Currency, from (and including) the relevant Early Termination
      Date to (but excluding) the date such amount is paid, at the Applicable
      Rate. Such interest will be calculated on the basis of daily compounding
      and the actual number of days elapsed.

(e) Payments on Early Termination. If an Early Termination Date occurs, the
following provisions shall apply based on the parties' election in the Schedule
of a payment measure, either "Market Quotation" or "Loss", and a payment method,
either the "First Method" or the "Second Method". If the parties fail to
designate a payment measure or payment method in the Schedule, it will be deemed
that "Market Quotation" or the "Second Method", as the case may be, shall apply.
The amount, if any, payable in respect of an Early Termination Date and
determined pursuant to this Section will be subject to any Set-off.

      (i) Events of Default. If the Early Termination Date results from an Event
      of Default:--

            (1) First Method and Market Quotation. If the First Method and
            Market Quotation apply, the Defaulting Party will pay to the
            Non-defaulting Party the excess, if a positive number, of (A) the
            sum of the Settlement Amount (determined by the Non-defaulting
            Party) in respect of the Terminated Transactions and the Termination
            Currency Equivalent of the Unpaid Amounts owing to the
            Non-defaulting Party over (B) the Termination Currency Equivalent of
            the Unpaid Amounts owing to the Defaulting Party.

            (2) First Method and Loss. If the First Method and Loss apply, the
            Defaulting Party will pay to the Non-defaulting Party, if a positive
            number, the Non-defaulting Party's Loss in respect of this
            Agreement.

            (3) Second Method and Market Quotation. If the Second Method and
            Market Quotation apply, an amount will be payable equal to (A) the
            sum of the Settlement Amount (determined by the

            Non-defaulting Party) in respect of the Terminated Transactions and
            the Termination Currency Equivalent of the Unpaid Amounts owing to
            the Non-defaulting Party less (B) the Termination Currency
            Equivalent of the Unpaid Amounts owing to the Defaulting Party. If
            that amount is a positive number, the Defaulting Party will pay it
            to the Non-defaulting Party; if it is a negative number, the
            Non-defaulting Party will pay the absolute value of that amount to
            the Defaulting Party.

            (4) Second Method and Loss. If the Second Method and Loss apply, an
            amount will be payable equal to the Non-defaulting Party's Loss in
            respect of this Agreement. If that amount is a positive number, the
            Defaulting Party will pay it to the Non-defaulting Party; if it is a
            negative number, the Non-defaulting Party will pay the absolute
            value of that amount to the Defaulting Party.

      (ii)Termination Events. If the Early Termination Date results from a
      Termination Event:--

            (1) One Affected Party. If there is one Affected Party, the amount
            payable will be determined in accordance with Section 6(e)(i)(3), if
            Market Quotation applies, or Section 6(e)(i)(4), if Loss applies,
            except that, in either case, references to the Defaulting Party and
            to the Non-defaulting Party will be deemed to be references to the
            Affected Party and the party which is not the Affected Party,
            respectively, and, if Loss applies and fewer than all the
            Transactions are being terminated, Loss shall be calculated in
            respect of all Terminated Transactions.

            (2) Two Affected Parties. If there are two Affected Parties:--

                  (A) if Market Quotation applies, each party will determine a
                  Settlement Amount in respect of the Terminated Transactions,
                  and an amount will be payable equal to (I) the sum of (a)
                  one-half of the difference between the Settlement Amount of
                  the party with the higher Settlement Amount ("X") and the
                  Settlement Amount of the party with the lower Settlement
                  Amount ("Y") and (b) the Termination Currency Equivalent of
                  the Unpaid Amounts owing to X less (II) the Termination
                  Currency Equivalent of the Unpaid Amounts owing to Y; and

                  (B) if Loss applies, each party will determine its Loss in
                  respect of this Agreement (or, if fewer than all the
                  Transactions are being terminated, in respect of all
                  Terminated Transactions) and an amount will be payable equal
                  to one-half of the difference between the Loss of the party
                  with the higher Loss ("X") and the Loss of the party with the
                  lower Loss ("Y").

      If the amount payable is a positive number, Y will pay it to X; if it is a
      negative number, X will pay the absolute value of that amount to Y.

      (iii) Adjustment for Bankruptcy. In circumstances where an Early
      Termination Date occurs because "Automatic Early Termination" applies in
      respect of a party, the amount determined under this Section 6(e) will be
      subject to such adjustments as are appropriate and permitted by law to
      reflect any payments or deliveries made by one party to the other under
      this Agreement (and retained by such other party) during the period from
      the relevant Early Termination Date to the date for payment determined
      under Section 6(d)(ii).

      (iv) Pre-Estimate. The parties agree that if Market Quotation applies an
      amount recoverable under this Section 6(e) is a reasonable pre-estimate of
      loss and not a penalty. Such amount is payable for the loss of bargain and
      the loss of protection against future risks and except as otherwise
      provided in this Agreement neither party will be entitled to recover any
      additional damages as a consequence of such losses.

7. Transfer

Subject to Section 6(b)(ii), neither this Agreement nor any interest or
obligation in or under this Agreement may be transferred (whether by way of
security or otherwise) by either party without the prior written consent of the
other party, except that: --

(a) a party may make such a transfer of this Agreement pursuant to a
consolidation or amalgamation with, or merger with or into, or transfer of all
or substantially all its assets to, another entity (but without prejudice to any
other right or remedy under this Agreement); and

(b) a party may make such a transfer of all or any part of its interest in any
amount payable to it from a Defaulting Party under Section 6(e).

Any purported transfer that is not in compliance with this Section will be void.

8. Contractual Currency

(a) Payment in the Contractual Currency. Each payment under this Agreement will
be made in the relevant currency specified in this Agreement for that payment
(the "Contractual Currency"). To the extent permitted by applicable law, any
obligation to make payments under this Agreement in the Contractual Currency
will not be discharged or satisfied by any tender in any currency other than the
Contractual Currency, except to the extent such tender results in the actual
receipt by the party to which payment is owed, acting in a reasonable manner and
in good faith in converting the currency so tendered into the Contractual
Currency, of the full amount in the Contractual Currency of all amounts payable
in respect of this Agreement. If for any reason the amount in the Contractual
Currency so received falls short of the amount in the Contractual Currency
payable in respect of this Agreement, the party required to make the payment
will, to the extent permitted by applicable law, immediately pay such additional
amount in the Contractual Currency as may be necessary to compensate for the
shortfall. If for any reason the amount in the Contractual Currency so received
exceeds the amount in the Contractual Currency payable in respect of this
Agreement, the party receiving the payment will refund promptly the amount of
such excess.

(b) Judgments. To the extent permitted by applicable law, if any judgment or
order expressed in a currency other than the Contractual Currency is rendered
(i) for the payment of any amount owing in respect of this Agreement, (ii) for
the payment of any amount relating to any early termination in respect of this
Agreement or (iii) in respect of a judgment or order of another court for the
payment of any amount described in (i) or (ii) above, the party seeking
recovery, after recovery in full of the aggregate amount to which such party is
entitled pursuant to the judgment or order, will be entitled to receive
immediately from the other party the amount of any shortfall of the Contractual
Currency received by such party as a consequence of sums paid in such other
currency and will refund promptly to the other party any excess of the
Contractual Currency received by such party as a consequence of sums paid in
such other currency if such shortfall or such excess arises or results from any
variation between the rate of exchange at which the Contractual Currency is
converted into the currency of the judgment or order for the purposes of such
judgment or order and the rate of exchange at which such party is able, acting
in a reasonable manner and in good faith in converting the currency received
into the Contractual Currency, to purchase the Contractual Currency with the
amount of the currency of the judgment or order actually received by such party.
The term "rate of exchange" includes, without limitation, any premiums and costs
of exchange payable in connection with the purchase of or conversion into the
Contractual Currency.

(c) Separate Indemnities. To the extent permitted by applicable law, these
indemnities constitute separate and independent obligations from the other
obligations in this Agreement, will be enforceable as separate and independent
causes of action, will apply notwithstanding any indulgence granted by the party
to which any payment is owed and will not be affected by judgment being obtained
or claim or proof being made for any other sums payable in respect of this
Agreement.

(d) Evidence of Loss. For the purpose of this Section 8, it will be sufficient
for a party to demonstrate that it would have suffered a loss had an actual
exchange or purchase been made.

9. Miscellaneous

(a) Entire Agreement. This Agreement constitutes the entire agreement and
understanding of the parties with respect to its subject matter and supersedes
all oral communication and prior writings with respect thereto.

(b) Amendments. No amendment, modification or waiver in respect of this
Agreement will be effective unless in writing (including a writing evidenced by
a facsimile transmission) and executed by each of the parties or confirmed by an
exchange of telexes or electronic messages on an electronic messaging system.

(c) Survival of Obligations. Without prejudice to Sections 2(a)(iii) and
6(c)(ii), the obligations of the parties under this Agreement will survive the
termination of any Transaction.

(d) Remedies Cumulative. Except as provided in this Agreement, the rights,
powers, remedies and privileges provided in this Agreement are cumulative and
not exclusive of any rights, powers, remedies and privileges provided by law.

(e) Counterparts and Confirmations.

      (i) This Agreement (and each amendment, modification and waiver in respect
      of it) may be executed and delivered in counterparts (including by
      facsimile transmission), each of which will be deemed an original.

      (ii) The parties intend that they are legally bound by the terms of each
      Transaction from the moment they agree to those terms (whether orally or
      otherwise). A Confirmation shall be entered into as soon as practicable
      and may be executed and delivered in counterparts (including by facsimile
      transmission) or be created by an exchange of telexes or by an exchange of
      electronic messages on an electronic messaging system, which in each case
      will be sufficient for all purposes to evidence a binding supplement to
      this Agreement. The parties will specify therein or through another
      effective means that any such counterpart, telex or electronic message
      constitutes a Confirmation.

(f) No Waiver of Rights. A failure or delay in exercising any right, power or
privilege in respect of this Agreement will not be presumed to operate as a
waiver, and a single or partial exercise of any right, power or privilege will
not be presumed to preclude any subsequent or further exercise, of that right,
power or privilege or the exercise of any other right, power or privilege.

(g) Headings. The headings used in this Agreement are for convenience of
reference only and are not to affect the construction of or to be taken into
consideration in interpreting this Agreement.

10. Offices; Multibranch Parties

(a) If Section 10(a) is specified in the Schedule as applying, each party that
enters into a Transaction through an Office other than its head or home office
represents to the other party that, notwithstanding the place of booking office
or jurisdiction of incorporation or organisation of such party, the obligations
of such party are the same as if it had entered into the Transaction through its
head or home office. This representation will be deemed to be repeated by such
party on each date on which a Transaction is entered into.

(b) Neither party may change the Office through which it makes and receives
payments or deliveries for the purpose of a Transaction without the prior
written consent of the other party.

(c) If a party is specified as a Multibranch Party in the Schedule, such
Multibranch Party may make and receive payments or deliveries under any
Transaction through any Office listed in the Schedule, and the Office through
which it makes and receives payments or deliveries with respect to a Transaction
will be specified in the relevant Confirmation.

11. Expenses

A Defaulting Party will, on demand, indemnify and hold harmless the other party
for and against all reasonable out-of-pocket expenses, including legal fees and
Stamp Tax, incurred by such other party by reason of the enforcement and
protection of its rights under this Agreement or any Credit Support Document to
which the Defaulting Party is a party or by reason of the early termination of
any Transaction, including, but not limited to, costs of collection.

12. Notices

(a) Effectiveness. Any notice or other communication in respect of this
Agreement may be given in any manner set forth below (except that a notice or
other communication under Section 5 or 6 may not be given by facsimile
transmission or electronic messaging system) to the address or number or in
accordance with the electronic messaging system details provided (see the
Schedule) and will be deemed effective as indicated:--

      (i) if in writing and delivered in person or by courier, on the date it is
      delivered;

      (ii)if sent by telex, on the date the recipient's answerback is received;

      (iii) if sent by facsimile transmission, on the date that transmission is
      received by a responsible employee of the recipient in legible form (it
      being agreed that the burden of proving receipt will be on the sender and
      will not be met by a transmission report generated by the sender's
      facsimile machine);

      (iv) if sent by certified or registered mail (airmail, if overseas) or the
      equivalent (return receipt requested), on the date that mail is delivered
      or its delivery is attempted; or

      (v) if sent by electronic messaging system, on the date that electronic
      message is received,

unless the date of that delivery (or attempted delivery) or that receipt, as
applicable, is not a Local Business Day or that communication is delivered (or
attempted) or received, as applicable, after the close of business on a Local
Business Day, in which case that communication shall be deemed given and
effective on the first following day that is a Local Business Day.

(b) Change of Addresses. Either party may by notice to the other change the
address, telex or facsimile number or electronic messaging system details at
which notices or other communications are to be given to it.

13. Governing Law and Jurisdiction

(a) Governing Law. This Agreement will be governed by and construed in
accordance with the law specified in the Schedule.

(b) Jurisdiction. With respect to any suit, action or proceedings relating to
this Agreement ("Proceedings"), each party irrevocably:--

      (i) submits to the jurisdiction of the English courts, if this Agreement
      is expressed to be governed by English law, or to the non-exclusive
      jurisdiction of the courts of the State of New York and the United States
      District Court located in the Borough of Manhattan in New York City, if
      this Agreement is expressed to be governed by the laws of the State of New
      York; and

      (ii) waives any objection which it may have at any time to the laying of
      venue of any Proceedings brought in any such court, waives any claim that
      such Proceedings have been brought in an inconvenient forum and further
      waives the right to object, with respect to such Proceedings, that such
      court does not have any jurisdiction over such party.

Nothing in this Agreement precludes either party from bringing Proceedings in
any other jurisdiction (outside, if this Agreement is expressed to be governed
by English law, the Contracting States, as defined in Section 1(3) of the Civil
Jurisdiction and Judgments Act 1982 or any modification, extension or
reenactment thereof for the time being in force) nor will the bringing of
Proceedings in any one or more jurisdictions preclude the bringing of
Proceedings in any other jurisdiction.

(c) Service of Process. Each party irrevocably appoints the Process Agent (if
any) specified opposite its name in the Schedule to receive, for it and on its
behalf, service of process in any Proceedings. If for any reason any party's
Process Agent is unable to act as such, such party will promptly notify the
other party and within 30 days appoint a substitute process agent acceptable to
the other party. The parties irrevocably consent to service of process given in
the manner provided for notices in Section 12. Nothing in this Agreement will
affect the right of either party to serve process in any other manner permitted
by law.

(d) Waiver of Immunities. Each party irrevocably waives, to the fullest extent
permitted by applicable law, with respect to itself and its revenues and assets
(irrespective of their use or intended use), all immunity on the grounds of
sovereignty or other similar grounds from (i) suit, (ii) jurisdiction of any
court, (iii) relief by way of injunction, order for specific performance or for
recovery of property, (iv) attachment of its assets (whether before or after
judgment) and (v) execution or enforcement of any judgment to which it or its
revenues or assets might otherwise be entitled in any Proceedings in the courts
of any jurisdiction and irrevocably agrees, to the extent permitted by
applicable law, that it will not claim any such immunity in any Proceedings.

"Loss" means, with respect to this Agreement or one or more Terminated
Transactions, as the case may be, and a party, the Termination Currency
Equivalent of an amount that party reasonably determines in good faith to be its
total losses and costs (or gain, in which case expressed as a negative number)
in connection with this Agreement or that Terminated Transaction or group of
Terminated Transactions, as the case may be, including any loss of bargain, cost
of funding or, at the election of such party but without duplication, loss or
cost incurred as a result of its terminating, liquidating, obtaining or
reestablishing any hedge or related trading position (or any gain resulting from
any of them). Loss includes losses and costs (or gains) in respect of any
payment or delivery required to have been made (assuming satisfaction of each
applicable condition precedent) on or before the relevant Early Termination Date
and not made, except, so as to avoid duplication, if Section 6(e)(i)(1) or (3)
or 6(e)(ii)(2)(A) applies. Loss does not include a party's legal fees and
out-of-pocket expenses referred to under Section 11. A party will determine its

relevant rates or prices from one or more leading dealers in the relevant
markets.

"Market Quotation" means, with respect to one or more Terminated Transactions
and a party making the determination, an amount determined on the basis of
quotations from Reference Market-makers. Each quotation will be for an amount,
if any, that would be paid to such party (expressed as a negative number) or by
such party (expressed as a positive number) in consideration of an agreement
between such party (taking into account any existing Credit Support Document
with respect to the obligations of such party) and the quoting Reference
Market-maker to enter into a transaction (the "Replacement Transaction") that
would have the effect of preserving for such party the economic equivalent of
any payment or delivery (whether the underlying obligation was absolute or
contingent and assuming the satisfaction of each applicable condition precedent)
by the parties under Section 2(a)(i) in respect of such Terminated Transaction
or group of Terminated Transactions that would, but for the occurrence of the
relevant Early Termination Date, have been required after that date. For this
purpose, Unpaid Amounts in respect of the Terminated Transaction or group of
Terminated Transactions are to be excluded but, without limitation, any payment
or delivery that would, but for the relevant Early Termination Date, have been
required (assuming satisfaction of each applicable condition precedent) after
that Early Termination Date is to be included. The Replacement Transaction would
be subject to such documentation as such party and the Reference Market-maker
may, in good faith, agree. The party making the determination (or its agent)
will request each Reference Market maker to provide its quotation to the extent
reasonably practicable as of the same day and time (without regard to different
time zones) on or as soon as reasonably practicable after the relevant Early
Termination Date. The day and time as of which those quotations are to be
obtained will be selected in good faith by the party obliged to make a
determination under Section 6(e), and, if each party is so obliged, after
consultation with the other. If more than three quotations are provided, the
Market Quotation will be the arithmetic mean of the quotations, without regard
to the quotations having the highest and lowest values. If exactly three such
quotations are provided, the Market Quotation will be the quotation remaining
after disregarding the highest and lowest quotations. For this purpose, if more
than one quotation has the same highest value or lowest value, then one of such
quotations shall be disregarded. If fewer than three quotations are provided, it
will be deemed that the Market Quotation in respect of such Terminated
Transaction or group of Terminated Transactions cannot be determined.

"Non-default Rate" means a rate per annum equal to the cost (without proof or
evidence of any actual cost) to the Non-defaulting Party (as certified by it) if
it were to fund the relevant amount.

"Office" means a branch or office of a party, which may be such party's head or
home office.

"Potential Event of Default" means any event which, with the giving of notice or
the lapse of time or both, would constitute an Event of Default.

"Reference Market-makers" means four leading dealers in the relevant market
selected by the party determining a Market Quotation in good faith (a) from
among dealers of the highest credit standing which satisfy all the criteria that
such party applies generally at the time in deciding whether to offer or to make
an extension of credit and (b) to the extent practicable, from among such
dealers having an office in the same city.

"Relevant Jurisdiction" means, with respect to a party, the jurisdictions (a) in
which the party is incorporated, organised, managed and controlled or considered
to have its seat, (b) where an Office through which the party is acting for
purposes of this Agreement is located, (c) in which the party executes this
Agreement and (d) in relation to any payment, from or through which such payment
is made.

"Scheduled Payment Date" means a date on which a payment or delivery is to be
made under Section 2(a)(i) with respect to a Transaction.

"Set-off" means set-off, offset, combination of accounts, right of retention or
withholding or similar right or requirement to which the payer of an amount
under Section 6 is entitled or subject (whether arising under this Agreement,
another contract, applicable law or otherwise) that is exercised by, or imposed
on, such payer.

"Settlement Amount" means, with respect to a party and any Early Termination
Date, the sum of:--

(a) the Termination Currency Equivalent of the Market Quotations (whether
positive or negative) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation is determined;
and

(b) such party's Loss (whether positive or negative and without reference to any
Unpaid Amounts) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation cannot be determined or would not (in
the reasonable belief of the party making the determination) produce a
commercially reasonable result.

"Specified Entity" has the meaning specified in the Schedule.

"Specified Indebtedness" means, subject to the Schedule, any obligation (whether
present or future, contingent or otherwise, as principal or surety or otherwise)
in respect of borrowed money.

"Specified Transaction" means, subject to the Schedule, (a) any transaction
(including an agreement with respect thereto) now existing or hereafter entered
into between one party to this Agreement (or any Credit Support Provider of such
party or any applicable Specified Entity of such party) and the other party to
this Agreement (or any Credit Support Provider of such other party or any
applicable Specified Entity of such other party) which is a rate swap
transaction, basis swap, forward rate transaction, commodity swap, commodity
option, equity or equity index swap, equity or equity index option, bond option,
interest rate option, foreign exchange transaction, cap transaction, floor
transaction, collar transaction, currency swap transaction, cross-currency rate
swap transaction, currency option or any other similar transaction (including
any option with respect to any of these transactions), (b) any combination of
these transactions and (c) any other transaction identified as a Specified
Transaction in this Agreement or the relevant confirmation.

"Stamp Tax" means any stamp, registration, documentation or similar tax.

"Tax" means any present or future tax, levy, impost, duty, charge, assessment or
fee of any nature (including interest, penalties and additions thereto) that is

under this Agreement other than a stamp, registration, documentation or similar
tax.

"Tax Event" has the meaning specified in Section 5(b).

Termination Date (or, if "Automatic Early Termination" applies, immediately
before that Early Termination Date).

"Termination Currency" has the meaning specified in the Schedule.

"Termination Currency Equivalent" means, in respect of any amount denominated in
the Termination Currency, such Termination Currency amount and, in respect of
any amount denominated in a currency other than the Termination Currency (the
"Other Currency"), the amount in the Termination Currency determined by the
party making the relevant determination as being required to purchase such
amount of such Other Currency as at the relevant Early Termination Date, or, if
the relevant Market Quotation or Loss (as the case may be), is determined as of
a later date, that later date, with the Termination Currency at the rate equal
to the spot exchange rate of the foreign exchange agent (selected as provided
below) for the purchase of such Other Currency with the Termination Currency at
or about 11:00 a.m. (in the city in which such foreign exchange agent is
located) on such date as would be customary for the determination of such a rate
for the purchase of such Other Currency for value on the relevant Early
Termination Date or that later date. The foreign exchange agent will, if only
one party is obliged to make a determination under Section 6(e), be selected in
good faith by that party and otherwise will be agreed by the parties.

"Termination Event" means an Illegality, a Tax Event or a Tax Event Upon Merger
or, if specified to be applicable, a Credit Event Upon Merger or an Additional
Termination Event.

"Termination Rate" means a rate per annum equal to the arithmetic mean of the
cost (without proof or evidence of any actual cost) to each party (as certified
by such party) if it were to fund or of funding such amounts.

"Unpaid Amounts" owing to any party means, with respect to an Early Termination
Date, the aggregate of (a) in respect of all Terminated Transactions, the
amounts that became payable (or that would have become payable but for Section
2(a)(iii)) to such party under Section 2(a)(i) on or prior to such Early
Termination Date and which remain unpaid as at such Early Termination Date and
(b) in respect of each Terminated Transaction, for each obligation under Section
2(a)(i) which was (or would have been but for Section 2(a) (iii)) required to be
settled by delivery to such party on or prior to such Early Termination Date and
which has not been so settled as at such Early Termination Date, an amount equal
to the fair market value of that which was (or would have been) required to be
delivered as of the originally scheduled date for delivery, in each case
together with (to the extent permitted under applicable law) interest, in the
currency, of such amounts, from (and including) the date such amounts or
obligations were or would have been required to have been paid or performed to
(but excluding) such Early Termination Date, at the Applicable Rate. Such
amounts of interest will be calculated on the basis of daily compounding and the
actual number of days elapsed. The fair market value of any obligation referred
to in clause (b) above shall be reasonably determined by the party obliged to
make the determination under Section 6(e) or, if each party is so obliged, it
shall be the average of the Termination Currency Equivalents of the fair market
values reasonably determined by both parties.

                                     Part 5

                                Other Provisions

(a) Definitions. Unless otherwise specified in a Confirmation, this Agreement
and each Transaction between the parties are subject to the 2000 ISDA
Definitions as published by the International Swaps and Derivatives Association,
Inc. (the "2000 Definitions"), and will be governed in all relevant respects by
the provisions set forth in the 2000 Definitions, without regard to any
amendment to the 2000 Definitions subsequent to the date hereof. The provisions
of the 2000 Definitions are incorporated by reference in and shall be deemed a
part of this Agreement, except that references in the 2000 Definitions to a
"Swap Transaction" shall be deemed references to a "Transaction" for purposes of
this Agreement. Terms defined in the Confirmations have the same meanings when
used in this Agreement except where otherwise defined.

(b) Independent Reliance. The parties agree to amend Section 3 of this Agreement
by the addition of the following provision at the end thereof and marked as
subsection (g).

      "(g)  Independent Reliance. Party A is entering into this Agreement and
            will enter into each Transaction in reliance upon such tax,
            accounting, regulatory, legal, and financial advice as it deems
            necessary and not upon any view expressed by the other party. Party
            B is entering into this Agreement and will enter into each
            Transaction in reliance upon the direction of the Depositor and not
            upon any view expressed by the other party."

(c) Change of Account. Section 2(b) of this Agreement is hereby amended by the
addition of the following after the word "delivery" in the first line thereof:

      "to another account in the same legal and tax jurisdiction as the original
      account"

(d) Recording of Conversations. Each party to this Agreement acknowledges and
agrees to the tape recording of conversations between the parties to this
Agreement whether by one or other or both of the parties and each party hereby
consents to such recordings being used as evidence in Proceedings.

(e) Waiver of Right to Trial by Jury. Each party waives, to the fullest extent
permitted by applicable law, any right it may have to a trial by jury in respect
of any suit, action or proceeding relating to this Agreement or any Credit
Support Document. Each party (i) certifies that no representative, agent or
attorney of the other party or any Credit Support Provider has represented,
expressly or otherwise, that such other party would not, in the event of such a
suit action or proceeding, seek to enforce the foregoing waiver and (ii)
acknowledges that it and the other party have been induced to enter into this
Agreement and provide for any Credit Support Document, as applicable by, among
other things, the mutual waivers and certifications in this Section.

(f) Pooling and Servicing Agreement.

      (1) Capitalized terms used in this Agreement that are not defined herein
      and are defined in the pooling and servicing agreement dated July 28,
      2006, among Wells Fargo Asset Securities Corporation, as Depositor, HSBC
      Bank USA, National Association, as Trustee, and Party B, as Master
      Servicer (the "Pooling and Servicing Agreement") shall have the respective
      meanings assigned to them in the Pooling and Servicing Agreement.

      (2) Notwithstanding any other provision of this Agreement, Party A may
      not, prior to the date which is one year and one day, or if longer the
      applicable preference period then in effect, after the payment in full of
      all Certificates, institute against, or join any other Person in
      instituting against, the Trust any bankruptcy, reorganization,
      arrangement, insolvency, moratorium or liquidation proceedings, or other
      proceedings under Federal, State, or bankruptcy or similar laws. Nothing
      shall preclude, or be deemed to stop, Party A (i) from taking any action
      prior to the expiration of the aforementioned one year and one day period,
      or if longer the applicable preference period then in effect, in (A) any
      case or proceeding voluntarily filed or commenced by the Trust or (B) any
      involuntary insolvency proceeding filed or commenced by a Person other
      than Party A, or (ii) from commencing against the Trust or any of the
      Collateral any legal action which is not a bankruptcy, reorganization,
      arrangement, insolvency, moratorium, liquidation or similar proceeding.
      Party A further acknowledges that Party B's obligations hereunder shall be
      solely the obligations of the Trust and that recourse in respect of any
      obligations of Party B hereunder will be limited to assets of the Trust as
      applied in accordance with the terms of the Pooling and Servicing
      Agreement and, on exhaustion thereof, all claims against Party B arising
      from this Agreement or contemplated hereby shall be extinguished.

(g) Transfer. Section 7 is hereby amended to read in its entirety as follows:

Except as stated under Section 6(b)(ii), in this Section 7, and except for the
assignment by way of security in favor of the Party B under the Pooling and
Servicing Agreement, neither Party A nor Party B is permitted to assign, novate
or transfer (whether by way of security or otherwise) as a whole or in part any
of its rights, obligations or interests under this Agreement or any Transaction
without the prior written consent of the other party; provided, however, that
(i) Party A may make such a transfer of this Agreement pursuant to a
consolidation or amalgamation with, or merger with or into, or transfer of
substantially all of its assets to, another entity, or an incorporation,
reincorporation or reconstitution, and (ii) with the written consent of Party B,
Party A may transfer this Agreement to any Person, including, without
limitation, another of Party A's offices, branches or affiliates (any such
Person, office, branch or affiliate, a "Transferee"); provided that, with
respect to clause (ii), (A) as of the date of such transfer the Transferee will
not be required to withhold or deduct on account of a Tax from any payments
under this Agreement unless the Transferee will be required to make payments of
additional amounts pursuant to Section 2(d)(i)(4) of this Agreement in respect
of such Tax (B) a Termination Event or Event of Default does not occur under
this Agreement as a result of such transfer; (C) such notice is accompanied by a
written instrument pursuant to which the Transferee acquires and assumes the
rights and obligations of Party A so transferred; and (D) Party A will be
responsible for any costs or expenses incurred in connection with such transfer.
Party B will execute such documentation as is reasonably deemed necessary by
Party A for the effectuation of any such transfer.

Except as specified otherwise in the documentation evidencing a transfer, a
transfer of all the obligations of Party A made in compliance with this Section
7 will constitute an acceptance and assumption of such obligations (and any
related interests so transferred) by the Transferee, a novation of the
transferee in place of Party A with respect to such obligations (and any related
interests so transferred), and a release and discharge by Party B of Party A
from, and an agreement by Party B not to make any claim for payment, liability,
or otherwise against Party A with respect to, such obligations from and after
the effective date of the transfer.

In addition, Party A may transfer this Agreement without the prior consent of
the Trustee, on behalf of Party B, to an affiliate that satisfies the
Counterparty Rating Requirement or that has furnished a guarantee of the
obligations under this Agreement from a guarantor that that satisfies the
Counterparty Rating Requirement.

(h) Notice of Certain Events or Circumstances. Each party agrees, upon learning
of the occurrence or existence of any event or condition that constitutes (or
that with the giving of notice or passage of time or both would constitute) an
Event of Default or Termination Event with respect to such party, promptly to
give the other party notice of such event or condition (or, in lieu of giving
notice of such event or condition in the case of an event or condition that with
the giving of notice or passage of time or both would constitute an Event of
Default or Termination Event with respect to the party, to cause such event or
condition to cease to exist before becoming an Event of Default or Termination
Event); provided that failure to provide notice of such event or condition
pursuant to this Part 5(h) shall not constitute an Event of Default or a
Termination Event.

(i) Regarding Party A. Party B acknowledges and agrees that Party A has had and
will have no involvement in and, accordingly Party A accepts no responsibility
for: (i) the establishment, structure, or choice of assets of the Trust; (ii)
the selection of any person performing services for or acting on behalf of Party
B or the Trust; (iii) the selection of Party A as the Counterparty; (iv) the
terms of the Certificates; (v) the preparation of or passing on the disclosure
and other information contained in any Prospectus Supplement for the
Certificates (other than the description of Party A provided by Party A to the
Depositor for inclusion in the Prospectus Supplement), the Pooling and Servicing
Agreement, or any other agreements or documents used by any party in connection
with the marketing and sale of the Certificates; (vi) the ongoing operations and
administration of the Trust, including the furnishing of any information to
Party B which is not specifically required under this Agreement; or (vii) any
other aspect of the Trust's existence.

(j) Commodity Exchange Act. Each party represents to the other party on and as
of the date hereof and on each date on which a Transaction is entered into among
them that:

      (i)   such party is an "eligible contract participant" as defined in the
            U.S. Commodity Exchange Act (the "CEA");

      (ii)  neither this Agreement nor any Transaction has been executed or
            traded on a "trading facility" as such term is defined in the CEA;
            and

      (iii) such party is entering into each Transaction in connection with its
            business or a line of business and the terms of this Agreement and
            each Transaction have been individually tailored and negotiated.

(k) Master Servicer Capacity. It is expressly understood and agreed by the
parties hereto that (i) this Agreement is executed and delivered by Wells Fargo
Bank, N.A., not in its individual capacity, but solely as Master Servicer, on
behalf of the Wells Fargo Mortgage Backed Securities 2006-10 Trust, in the
exercise of the powers and authority conferred upon and vested in it thereunder,
(ii) each of the representations, warranties, covenants, undertakings and
agreements herein made on the part of Party B has not been made or intended as a
representation, warranty, covenant, undertaking or agreement by Wells Fargo
Bank, N.A., in its individual capacity, but is made and intended for the purpose
of binding only the assets of the Trust available therefor in accordance with
the terms of the Pooling and Servicing Agreement, (iii) nothing herein contained
shall be construed as creating any liability on Wells Fargo Bank, N.A., in its
individual capacity, to perform any covenant either expressed or implied
contained herein, all such liability, if any, being expressly waived by the
parties hereto and by any Person claiming by, through or under the parties
hereto and (iv) under no circumstances shall Wells Fargo Bank, N.A., in its
individual capacity, be liable for the payment of any indebtedness or expenses
of Party B or be liable for the breach or failure of any obligation,
representation, warranty or covenant made or undertaken by Party B under this
Agreement or any other related document, as to all of which recourse shall be
had solely to the assets of the Trust in accordance with the terms of the
Pooling and Servicing Agreement.

(l) Compliance with Regulation AB.

      (i) Party A acknowledges that for so long as there are reporting
      obligations with respect to this Transaction under Regulation AB, the
      Depositor, acting on behalf of the Wells Fargo Mortgage Backed Securities
      2006-10 Trust (the "Issuing Entity"), is required under Regulation AB
      under the Securities Act of 1933, as amended, and the Securities Exchange
      Act of 1934, as amended ("Regulation AB"), to disclose certain information
      set forth in Regulation AB regarding Party A or its group of affiliated
      entities, if applicable, depending on the aggregate "significance
      percentage" of this Agreement and any other derivative contracts between
      Party A or its group of affiliated entities, if applicable, and Party B,
      as calculated from time to time in accordance with Item 1115 of Regulation
      AB.

      (ii) If the Depositor determines, reasonably and in good faith, that the
      significance percentage of this Agreement has increased to nine (9)
      percent or more, then the Depositor may request on a Business Day on or
      after the date of such determination from Party A the same information set
      forth in Item 1115(b)(1) of Regulation AB that would have been required if
      the significance percentage had in fact increased to ten (10) percent,
      along with any necessary auditors' consent (such request, a "10% Cap
      Disclosure Request" and such requested information, subject to the last
      sentence of this paragraph, is the "10% Cap Financial Disclosure"). Party
      B or the Depositor shall provide Party A with the calculations and any
      other information reasonably requested by Party A with respect to the
      Depositor's determination that led to the 10% Cap Disclosure Request. The
      parties hereto further agree that the 10% Cap Financial Disclosure
      provided to meet the 10% Cap Disclosure Request may be, solely at Party
      A's option, either the information set forth in Item 1115(b)(1) or Item
      1115(b)(2) of Regulation AB.

      (iii) So long as there are reporting obligations with respect to this
      Transaction under Regulation AB, upon the occurrence of a 10% Cap
      Disclosure Request, Party A, at its own expense, shall (i) provide the
      Depositor with the 10% Cap Financial Disclosure, (ii) secure another
      entity to replace Party A as party to this Agreement on terms
      substantially similar to this Agreement which entity is able to (A)
      provide the 10% Cap Financial Disclosure and (B) provide an indemnity to
      the Depositor, reasonably satisfactory to the Depositor, in relation to
      the 10% Cap Financial Disclosure or (iii) obtain a guaranty of Party A's
      obligations under this Agreement from an affiliate of Party A that is able
      to (A) provide the 10% Cap Financial Disclosure, such that disclosure
      provided in respect of the affiliate will, in the judgment of counsel to
      the Depositor, satisfy any disclosure requirements applicable to Party A,
      and cause such affiliate to provide 10% Cap Financial Disclosure and (B)
      provide an indemnity to the Depositor, reasonably satisfactory to the
      Depositor, in relation to the 10% Cap Financial Disclosure. If permitted
      by Regulation AB, any required 10% Cap Financial Disclosure may be
      provided by incorporation by reference from reports filed pursuant to the
      Securities Exchange Act.

      (iv) If the Depositor determines, reasonably and in good faith, that the
      significance percentage of this Agreement has increased to nineteen (19)
      percent or more, then the Depositor may request on a Business Day on or
      after the date of such determination from Party A the same information set
      forth in Item 1115(b)(2) of Regulation AB that would have been required if
      the significance percentage had in fact increased to twenty (20) percent,
      along with any necessary auditors consent (such request, a "20% Cap
      Disclosure Request" and such requested information is the "20% Cap
      Financial Disclosure"). Party B or the Depositor shall provide Party A
      with the calculations and any other information reasonably requested by
      Party A with respect to the Depositor's determination that led to the 20%
      Cap Disclosure Request.

      (v) So long as there are reporting obligations with respect to this
      Transaction under Regulation AB, upon the occurrence of a 20% Cap
      Disclosure Request, Party A, at its own expense, shall (i) provide the
      Depositor with the 20% Cap Financial Disclosure, (ii) secure another
      entity to replace Party A as party to this Agreement on terms
      substantially similar to this Agreement which entity is able to (A)
      provide the 20% Cap Financial Disclosure and (B) provide an indemnity to
      the Depositor, reasonably satisfactory to the Depositor, in relation to
      the 20% Cap Financial Disclosure or (iii) obtain a guaranty of Party A's
      obligations under this Agreement from an affiliate of Party A that is able
      to (A) provide the 20% Cap Financial Disclosure, such that disclosure
      provided in respect of the affiliate will, in the judgment of counsel to
      the Depositor, satisfy any disclosure requirements applicable to Party A,
      and cause such affiliate to provide 20% Cap Financial Disclosure and (B)
      provide an indemnity to the Depositor, reasonably satisfactory to the
      Depositor, in relation to the 20% Cap Financial Disclosure. If permitted
      by Regulation AB, any required 20% Cap Financial Disclosure may be
      provided by incorporation by reference from reports filed pursuant to the
      Securities Exchange Act.

(m) Fully Paid Transactions. Notwithstanding the terms of Sections 5 and 6 of
the Agreement, if at any time and so long as Party B shall have satisfied in
full all its payment and delivery obligations under Section 2(a)(i) of the
Agreement and the Credit Support Annex and shall at the time have no future
payment or delivery obligations, whether absolute or contingent, under such
Section or the Credit Support Annex, then unless Party A is required pursuant to
appropriate proceedings to return to Party B or otherwise returns to Party B
(upon demand of Party B, or otherwise) any portion of any such payment or
delivery: (i) the occurrence of an event described in Section 5(a) of the
Agreement with respect to Party B shall not constitute an Event of Default or a
Potential Event of Default with respect to Party B as the Defaulting Party; and
(ii) Party A shall be entitled to designate an Early Termination Date pursuant
to Section 6 of the Agreement only as a result of the occurrence of a
Termination Event set forth in (i) either Section 5(b)(i) or 5(b)(ii) of the
Agreement with respect to Party A as the Affected Party or (ii) Section
5(b)(iii) of the Agreement with respect to Party A as the Burdened Party.
