                  for an amount that would be paid to Party B (expressed as a

                  number) in consideration of an agreement between Party B and
                  such Reference Market-maker to enter into a Replacement
                  Transaction, and (3) made on the basis that Unpaid Amounts in
                  respect of the Terminated Transaction or group of 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.

            (B)   The definition of Settlement Amount shall be deleted in its
                  entirety and replaced with the following:

                  "Settlement Amount" means, with respect to any Early
                  Termination Date, an amount equal to:

                  (a)   If a Market Quotation for the relevant Terminated
                        Transaction or group of Terminated Transactions is
                        accepted by Party B so as to become legally binding on
                        or before the day falling ten Local Business Days after
                        the day on which the Early Termination Date is
                        designated, or such later day as Party B may specify in
                        writing to Party A, but in either case no later than one
                        Local Business Day prior to the Early Termination Date
                        (such day, the "Latest Settlement Amount Determination
                        Day"), the Termination Currency Equivalent of the amount
                        (whether positive or negative) of such Market Quotation;

                  (b)   If, on the Latest Settlement Amount Determination Day,
                        no Market Quotation for the relevant Terminated
                        Transaction or group of Terminated Transactions has been
                        accepted by Party B so as to become legally binding and
                        one or more Market Quotations from Approved Replacements
                        have been made and remain capable of becoming legally
                        binding upon acceptance, the Settlement Amount shall
                        equal the Termination Currency Equivalent of the amount
                        (whether positive or negative) of the lowest of such
                        Market Quotations (for the avoidance of doubt, the
                        lowest of such Market Quotations shall be the lowest
                        Market Quotation of such Market Quotations expressed as
                        a positive number or, if any of such Market Quotations
                        is expressed as a negative number, the Market Quotation
                        expressed as a negative number with the largest absolute
                        value); or

                  (c)   If, on the Latest Settlement Amount Determination Day,
                        no Market Quotation for the relevant Terminated
                        Transaction or group of Terminated Transactions is
                        accepted by Party B so as to become legally binding and
                        no Market Quotation from an Approved Replacement remains
                        capable of becoming legally binding upon acceptance, the
                        Settlement Amount shall equal Party B's Loss (whether
                        positive or negative and without reference to any Unpaid
                        Amounts) for the relevant Terminated Transaction or
                        group of Terminated Transactions.

            (C)   Party A may obtain Market Quotations, and if Party B requests
                  Party A in writing to obtain Market Quotations, Party A shall

            respect to this Transaction pursuant to Regulation AB and (2) Party
            A has not, within 30 days after receipt of a 20% Disclosure Request
            (as defined below) complied with the provisions set forth in clauses
            (iv) and (v) of Part 5(q) below (provided that if the significance
            percentage is 20% or more when the 20% Disclosure Request is made or
            reaches 20% after a 20% Disclosure Request has been made to Party A,
            Party A must comply with the provisions set forth in clauses (iv)
            and (v) of Part 5(q) below within 3 calendar days of Party A being
            informed of the significance percentage reaching 20% or more), then
            an Additional Termination Event shall have occurred with respect to
            Party A and Party A shall be the sole Affected Party with respect to
            such Additional Termination Event.

(d)   Required Ratings Downgrade Event. In the event that no Relevant Entity has
      credit ratings at least equal to the Required Ratings Threshold of each
      relevant Swap Rating Agency (such event, a "Required Ratings Downgrade
      Event"), then Party A shall, as soon as reasonably practicable and so long
      as a Required Ratings Downgrade Event is in effect, at its own expense,
      use commercially reasonable efforts to procure either (A) a Permitted
      Transfer or (B) an Eligible Guarantee from an Eligible Guarantor.

(e)   Transfers.

      (i) Section 7 is hereby amended to read in its entirety as follows:

            "Subject to Section 6(b)(ii), 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 the Agreement or any Transaction without (a) the
            prior written consent of the other party and (b) satisfaction of the
            Rating Agency Condition, 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);

            (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); and

            (c)   Party A may transfer or assign 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") on at least five Business Days'
                  prior written notice to Party B and the Securities
                  Administrator; provided that, with respect to this clause (c),
                  (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; (D) Party A will be
                  responsible for any costs or expenses incurred in connection
                  with such transfer and (E) Party A obtains in respect of such
                  transfer a written acknowledgement of satisfaction of the
                  Rating Agency Condition (except for Moody's). Party B will
                  execute such documentation as is reasonably deemed necessary
                  by Party A for the effectuation of any such transfer."

      (ii)  If an Eligible Replacement has made a Firm Offer (which remains an
            offer that will become legally binding upon acceptance by Party B)
            to be the transferee pursuant to a Permitted Transfer, Party B
            shall, at Party A's written request and at Party A's expense, take
            any reasonable steps required to be taken by Party B to effect such
            transfer.

      (iii) Upon any transfer of this Agreement, each of the transferee and the
            transferor must be a "dealer in notional principal contracts" for
            purposes of Treasury regulations section 1.1001-4(a). For the
            avoidance of doubt, the Securities Administrator on behalf of Party
            B is not obligated to determine whether each of the transferee and
            the transferor are such "dealers in notional principal contracts."

(f)   Non-Recourse. Party A acknowledges and agree that, notwithstanding any
      provision in this Agreement to the contrary, the obligations of Party B
      hereunder are limited recourse obligations of Party B, payable solely from
      the Trust and the proceeds thereof, in accordance with the priority of
      payments and other terms of the Base Agreement and that Party A will not
      have any recourse to any of the directors, officers, employees,
      shareholders or affiliates of Party B with respect to any claims, losses,
      damages, liabilities, indemnities or other obligations in connection with
      any transactions contemplated hereby. In the event that the Trust and the
      proceeds thereof, should be insufficient to satisfy all claims outstanding
      and following the realization of the account held by the Trust and the
      proceeds thereof, any claims against or obligations of Party B under the
      ISDA Master Agreement or any other confirmation thereunder still
      outstanding shall be extinguished and thereafter not revive. The
      Securities Administrator shall not have liability for any failure or delay
      in making a payment hereunder to Party A due to any failure or delay in
      receiving amounts in the account held by the Trust from the Trust created
      pursuant to the Base Agreement. This provision will survive the
      termination of this Agreement.

(g)   Rating Agency Notifications. Notwithstanding any other provision of this
      Agreement, no Early Termination Date shall be effectively designated
      hereunder by Party B and no transfer of any rights or obligations under
      this Agreement shall be made by either party unless each Swap Rating
      Agency has been given prior written notice of such designation or
      transfer.

(h)   No Set-off. Except as expressly provided for in Section 2(c), Section 6 or
      Part 1(f)(i)(D) hereof, and notwithstanding any other provision of this
      Agreement or any other existing or future agreement, each party
      irrevocably waives any and all rights it may have to set off, net, recoup
      or otherwise withhold or suspend or condition payment or performance of
      any obligation between it and the other party hereunder against any
      obligation between it and the other party under any other agreements.
      Section 6(e) shall be amended by deleting the following sentence: "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)   Amendment. Notwithstanding any provision to the contrary in this
      Agreement, no amendment of either this Agreement or any Transaction under
      this Agreement shall be permitted by either party unless each of the Swap
      Rating Agencies has been provided prior written notice of the same and
      each relevant Swap Rating Agency (other than Moody's) confirms in writing
      (including by facsimile transmission) that it will not downgrade, withdraw
      or otherwise modify its then-current ratings of the Certificates.

(j)   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 and to each Swap Rating
      Agency notice of such event or condition; provided that failure to provide
      notice of such event or condition pursuant to this Part 5(j) shall not
      constitute an Event of Default or a Termination Event.

(k)   Proceedings. No Relevant Entity shall institute against, or cause any
      other person to institute against, or join any other person in instituting
      against Party B, the Trust, or the trust formed pursuant to the Base
      Agreement, in any bankruptcy, reorganization, arrangement, insolvency or
      liquidation proceedings or other proceedings under any federal or state
      bankruptcy or similar law for a period of one year (or, if longer, the
      applicable preference period) and one day following payment in full of the
      Certificates; provided, however, that nothing will 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 Party B or (B) any involuntary
      insolvency proceeding filed or commenced by a Person other than Party A,
      or (ii) from commencing against Party B or any of the Collateral any legal
      action which is not a bankruptcy, reorganization, arrangement, insolvency,
      moratorium, liquidation or similar proceeding. This provision will survive
      the termination of this Agreement.

(l)   Securities Administrator Liability Limitations. It is expressly understood
      and agreed by the parties hereto that (a) this Agreement is executed by
      Wells Fargo Bank, National Association ("Wells Fargo") not in its
      individual capacity, but solely as Securities Administrator under the Base
      Agreement in the exercise of the powers and authority conferred and
      invested in it thereunder; (b) Wells Fargo has been directed pursuant to
      the Base Agreement to enter into this Agreement and to perform its
      obligations hereunder; (c) each of the representations, undertakings and
      agreements herein made on behalf of the Trust is made and intended not as
      personal representations of Wells Fargo but is made and intended for the
      purpose of binding only the Trust; and (d) under no circumstances shall
      Wells Fargo in its individual capacity be personally liable for any
      payments hereunder or for the breach or failure of any obligation,
      representation, warranty or covenant made or undertaken under this
      Agreement.

(m)   Severability. If any term, provision, covenant, or condition of this
      Agreement, or the application thereof to any party or circumstance, shall
      be held to be invalid or unenforceable (in whole or in part) in any
      respect, the remaining terms, provisions, covenants, and conditions hereof
      shall continue in full force and effect as if this Agreement had been
      executed with the invalid or unenforceable portion eliminated, so long as
      this Agreement as so modified continues to express, without material
      change, the original intentions of the parties as to the subject matter of
      this Agreement and the deletion of such portion of this Agreement will not
      substantially impair the respective benefits or expectations of the
      parties; provided, however, that this severability provision shall not be
      applicable if any provision of Section 2, 5, 6, or 13 (or any definition
      or provision in Section 14 to the extent it relates to, or is used in or
      in connection with any such Section) shall be so held to be invalid or
      unenforceable.

      The parties shall endeavor to engage in good faith negotiations to replace
      any invalid or unenforceable term, provision, covenant or condition with a
      valid or enforceable term, provision, covenant or condition, the economic
      effect of which comes as close as possible to that of the invalid or
      unenforceable term, provision, covenant or condition.

(n)   Consent to Recording. Each party hereto consents to the monitoring or
      recording, at any time and from time to time, by the other party of any
      and all communications between trading, marketing, and operations
      personnel of the parties and their Affiliates, waives any further notice
      of such monitoring or recording, and agrees to notify such personnel of
      such monitoring or recording.

(o)   Waiver of Jury Trial. Each party waives any right it may have to a trial
      by jury in respect of any in respect of any suit, action or proceeding
      relating to this Agreement or any Credit Support Document.

(p)   Regarding Party A. Party B acknowledges and agrees that Party A, in its
      capacity as swap provider, 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 Party B; (ii) the selection of any
      person performing services for or acting on behalf of Party B; (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 (other than disclosure and information furnished by
      Party A) contained in any offering document for the Certificates, the Base
      Agreement, or any other agreements or documents used by Party B or any
      other party in connection with the marketing and sale of the Certificates;
      (vi) the ongoing operations and administration of Party B, including the
      furnishing of any information to Party B which is not specifically
      required under this Agreement; or (vii) any other aspect of Party B's
      existence.

(q)   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 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 (and any other derivative
            contracts between Party A or its group of affiliated entities, if
            applicable, and Party B) has increased to eight (8) percent or more
            but less than eighteen (18) percent, then the Depositor may request
            on the date of such determination (or, if such date of determination
            is not a Business Day, the immediately following Business Day) 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% Disclosure
            Request" and such requested information, subject to the last
            sentence of this paragraph, is the "10% Financial Disclosure"). 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% Disclosure Request.
            The parties hereto further agree that the 10% Financial Disclosure
            provided to meet the 10% 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) Upon the occurrence of a 10% Disclosure Request, Party A, at its own
            expense, shall (i) provide the Depositor with the 10% Financial
            Disclosure, (ii) subject to Rating Agency Confirmation, 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% Financial Disclosure and (B) provide an
            indemnity to the Depositor, reasonably satisfactory to the
            Depositor, in relation to the 10% Financial Disclosure or (iii)
            subject to Rating Agency Confirmation, 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% 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% Financial Disclosure and (B) provide an indemnity to the
            Depositor, reasonably satisfactory to the Depositor, in relation to
            the 10% Financial Disclosure. Any such 10% Financial Disclosure
            provided pursuant to this paragraph (iii) shall be in a form
            suitable for conversion to the format required for filing by the
            Depositor with the Securities and Exchange Commission via the
            Electronic Data Gathering and Retrieval System (EDGAR). If permitted
            by Regulation AB, any required 10% 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 (and any other derivative
            contracts between Party A or its group of affiliated entities, if
            applicable, and Party B) has increased to eighteen (18) percent or
            more, then the Depositor may request on the date of such
            determination (or, if such date of determination is not a Business
            Day, the immediately following Business Day) 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% Disclosure Request" and such requested
            information is the "20% 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% Disclosure Request.

      (v)   Upon the occurrence of a 20% Disclosure Request, Party A, at its own
            expense, shall (i) provide the Depositor with the 20% Financial
            Disclosure, (ii) subject to Rating Agency Confirmation, 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% Financial Disclosure and (B) provide an
            indemnity to the Depositor, reasonably satisfactory to the
            Depositor, in relation to the 20% Financial Disclosure or (iii)
            subject to Rating Agency Confirmation, 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% 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% Financial Disclosure and (B) provide an indemnity to the
            Depositor, reasonably satisfactory to the Depositor, in relation to
            the 20% Financial Disclosure. Any such 20% Financial Disclosure
            provided pursuant to this paragraph (v) shall be in a form suitable
            for conversion to the format required for filing by the Depositor
            with the Securities and Exchange Commission via the Electronic Data
            Gathering and Retrieval System (EDGAR). If permitted by Regulation
            AB, any required 20% Financial Disclosure may be provided by
            incorporation by reference from reports filed pursuant to the
            Securities Exchange Act.

(r)   Additional Definitions.

      Capitalized terms used herein and not otherwise defined herein shall have
      the meanings assigned to such terms in the Base Agreement. In addition, as
      used in this Agreement, the following terms shall have the meanings set
      forth below, unless the context clearly requires otherwise:

            "Approved Ratings Threshold" means each of the S&P Approved Ratings
            Threshold, the Moody's First Trigger Ratings Threshold and the Fitch
            First Trigger Ratings Threshold.

            "Approved Replacement" means, with respect to a Market Quotation, an
            entity making such Market Quotation, which entity would satisfy
            conditions (a), (b), (c) and (e) of the definition of Permitted
            Transfer if such entity were a Transferee, as defined in the
            definition of Permitted Transfer.

            "Derivative Provider Trigger Event" means (i) an Event of Default
            with respect to which Party A is a Defaulting Party, (ii) a
            Termination Event (other than Illegality or Tax Event) with respect
            to which Party A is the sole Affected Party or (iii) an Additional
            Termination Event with respect to which Party A is the sole Affected
            Party.

            "Eligible Guarantee" means an unconditional and irrevocable
            guarantee of all present and future obligations (for the avoidance
            of doubt, not limited to payment obligations) of Party A or an
            Eligible Replacement to Party B under this Agreement that is
            provided by an Eligible Guarantor as principal debtor rather than
            surety and that is directly enforceable by Party B, the form and
            substance of which guarantee are subject to the Rating Agency
            Condition, and either (A) a law firm has given a legal opinion
            confirming that none of the guarantor's payments to Party B under
            such guarantee will be subject to Tax collected by withholding or
            (B) such guarantee provides that, in the event that any of such
            guarantor's payments to Party B are subject to Tax collected by
            withholding, such guarantor is required to pay such additional
            amount as is necessary to ensure that the net amount actually
            received by Party B (free and clear of any Tax collected by
            withholding) will equal the full amount Party B would have received
            had no such withholding been required.

            "Eligible Guarantor" means an entity that (A) has credit ratings at
            least equal to the Approved Ratings Threshold or (B) has credit
            ratings at least equal to the Required Ratings Threshold, provided,

            Eligible Guarantor with credit ratings below the Approved Ratings
            Threshold will not cause a Collateral Event (as defined in the
            Credit Support Annex) not to occur or continue.

            "Eligible Replacement" means an entity (A) that has credit ratings
            at least equal to the Approved Ratings Threshold, (B) has credit
            ratings at least equal to the Required Ratings Threshold, provided,
            for the avoidance of doubt, that an Eligible Guarantee of an
            Eligible Guarantor with credit ratings below the Approved Ratings

            (C)   "Minimum Transfer Amount" means USD 100,000 with respect to

                  be more than USD 50,000,000, "Minimum Transfer Amount" means
                  USD 50,000, and provided further, with respect to the Secured

            Support Provider has a long-term unsubordinated and unsecured debt
            rating of at least "BBB+" from S&P, the Valuation Agent shall (A)
            calculate the Secured Party's Exposure and the S&P Value of Posted
            Credit Suppport on each Valuation Date based on internal marks and
            (B) verify such calculations with external marks monthly by
            obtaining on the last Local Business Day of each calendar month two
            external marks for each Transaction to which this Annex relates and
            for all Posted Credit Suport; such verification of the Secured
            Party's Exposure shall be based on the higher of the two external
            marks. Each external mark in respect of a Transaction shall be
            obtained from an independent Reference Market-maker that would be
            eligible and willing to enter into such Transaction in the absence
            of the current derivative provider, provided that an external mark
            may not be obtained from the same Reference Market-maker more than
            four times in any 12-month period. The Valuation Agent shall obtain
            these external marks directly or through an independent third party,
            in either case at no cost to Party B. The Valuation Agent shall
            calculate on each Valuation Date (for purposes of this paragraph,
            the last Local Business Day in each calendar month referred to above
            shall be considered a Valuation Date) the Secured Party's Exposure
            based on the greater of the Valuation Agent's internal marks and the
            external marks received. If the S&P Value on any such Valuation Date
            of all Posted Credit Support then held by the Secured Party is less
            than the S&P Credit Support Amount on such Valuation Date (in each
            case as determined pursuant to this paragraph), Party A shall,
            within three Local Business Days of such Valuation Date, Transfer to
            the Secured Party Eligible Credit Support having an S&P Value as of
            the date of Transfer at least equal to such deficiency.

            extent applicable, its Credit Support Provider has a long-term
            unsubordinated and unsecured debt rating of at least "BBB+" from
            S&P, the Valuation Agent shall provide to S&P not later than the
            Notification Time on the Local Business Day following each Valuation
            Date its calculations of the Secured Party's Exposure and the S&P
            Value of any Eligible Credit Support or Posted Credit Support for
            that Valuation Date. The Valuation Agent shall also provide to S&P
            any external marks received pursuant to the preceding paragraph.

(d)   Conditions Precedent and Secured Party's Rights and Remedies. The
      following Termination Events will be a "Specified Condition" for the party

            Value, Moody's First Trigger Value, and Moody's Second Trigger
            Value, on any date, of Eligible Collateral will be calculated as
            follows:

            For Eligible Collateral comprised of Cash, the amount of such Cash.

            For Eligible Collateral comprising securities, the sum of (A) the
            product of (1)(x) the bid price at the Valuation Time for such
            securities on the principal national securities exchange on which
            such securities are listed, or (y) if such securities are not listed
            on a national securities exchange, the bid price for such securities
            quoted at the Valuation Time by any principal market maker for such
            securities selected by the Valuation Agent, or (z) if no such bid

            applicable Valuation Percentage for such Eligible Collateral, and
            (B) the accrued interest on such securities (except to the extent
            Transferred to the Pledgor pursuant to Paragraph 6(d)(ii) or
            included in the applicable price referred to in the immediately
            preceding clause (A)) as of such date.

            that the obligation of the appropriate party to deliver the
            undisputed amount to the other party will not arise prior to the
            time that would otherwise have applied to the Transfer pursuant to,
            or deemed made, under Paragraph 3 if no dispute had arisen.

            Party B to Party A.

      (ii)  Use of Posted Collateral. The provisions of Paragraph 6(c) will not

            specified in Paragraph 6(c)(i) or 6 (c)(ii); provided, however, that
            the Securities Administrator shall invest Cash Posted Credit Support

      to Party A, Party A must comply with the provisions set forth in clauses
      (ii) and (iii) of Paragraph 7(g) below within 3 calendar days of Party A
      being informed of the significance percentage reaching 10% or more), then

            (B) If (1) the Depositor still has a reporting obligation with

(g) 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 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 (and any other derivative
      contracts between Party A or its group of affiliated entities, if
      applicable, and Party B) has increased to eight (8) percent or more but
      less than eighteen (18) percent, then the Depositor may request on the
      date of such determination (or, if such date of determination is not a
      Business Day, the immediately following Business Day) 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% Disclosure Request" and such requested information,
      subject to the last sentence of this paragraph, is the "10% 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%
      Disclosure Request. The parties hereto further agree that the 10%
      Financial Disclosure provided to meet the 10% 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) Upon the occurrence of a 10% Disclosure Request, Party A, at its own
      expense, shall (i) provide the Depositor with the 10% Financial
      Disclosure, (ii) subject to Rating Agency Confirmation, 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% Financial Disclosure and (B) provide an indemnity to the
      Depositor, reasonably satisfactory to the Depositor, in relation to the
      10% Financial Disclosure or (iii) subject to Rating Agency Confirmation,
      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% 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% Financial Disclosure and (B) provide an indemnity to the Depositor,
      reasonably satisfactory to the Depositor, in relation to the 10% Financial
      Disclosure. Any such 10% Financial Disclosure provided pursuant to this
      paragraph (iii) shall be in a form suitable for conversion to the format
      required for filing by the Depositor with the Securities and Exchange
      Commission via the Electronic Data Gathering and Retrieval System (EDGAR).
      If permitted by Regulation AB, any required 10% 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 (and any other derivative
      contracts between Party A or its group of affiliated entities, if
      applicable, and Party B) has increased to eighteen (18) percent or more,
      then the Depositor may request on the date of such determination (or, if
      such date of determination is not a Business Day, the immediately
      following Business Day) 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% Disclosure
      Request" and such requested information is the "20% 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%
      Disclosure Request.

      (v) Upon the occurrence of a 20% Disclosure Request, Party A, at its own
      expense, shall (i) provide the Depositor with the 20% Financial
      Disclosure, (ii) subject to Rating Agency Confirmation, 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% Financial Disclosure and (B) provide an indemnity to the
      Depositor, reasonably satisfactory to the Depositor, in relation to the
      20% Financial Disclosure or (iii) subject to Rating Agency Confirmation,
      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% 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% Financial Disclosure and (B) provide an indemnity to the Depositor,
      reasonably satisfactory to the Depositor, in relation to the 20% Financial
      Disclosure. Any such 20% Financial Disclosure provided pursuant to this
      paragraph (v) shall be in a form suitable for conversion to the format
      required for filing by the Depositor with the Securities and Exchange
      Commission via the Electronic Data Gathering and Retrieval System (EDGAR).
      If permitted by Regulation AB, any required 20% Financial Disclosure may
      be provided by incorporation by reference from reports filed pursuant to
      the Securities Exchange Act.
