        customary  for the  relevant  obligation  unless  otherwise  specified in the relevant
        Confirmation or elsewhere in this Agreement.

(a) DEFINITIONS.

    Any  capitalized  terms used but not otherwise  defined in this  Agreement  shall have the
    meanings  assigned to them (or  incorporated by reference) in the PSA. In the event of any

    Agreement will govern.

(b) DOWNGRADE PROVISIONS.

    (1) It shall be a collateralization event (COLLATERALIZATION EVENT) if:

           (A) with respect to each Relevant  Entity,  so long as Moody's  Investor  Services,
           Inc.  (MOODY'S) is currently  rating the  Certificates and either (i) such Relevant
           Entity  has  both  a  long-term  and  short-term  rating  by  Moody's  and  (x) the
           unsecured,   unguaranteed   and  otherwise   unsupported   long-term   senior  debt
           obligations  of such Relevant  Entity are rated "A3" or below by Moody's or (y) the
           unsecured,  unguaranteed and otherwise  unsupported  short-term debt obligations of
           such  Relevant  Entity are rated "P-2" or below by Moody's,  or (ii) no  short-term
           rating is available  from Moody's and the  unsecured,  unguaranteed  and  otherwise
           unsupported  long-term  senior debt  obligations of such Relevant  Entity are rated
           "A2" or below by Moody's (such event, a MOODY'S COLLATERALIZATION EVENT), or

           the  Certificates  and  either  (i)  the  unsecured,   unguaranteed  and  otherwise
           unsupported  short-term  debt  obligations of such Relevant  Entity are rated "A-2"
           or below by S&P or (ii) if such Relevant  Entity does not have a short-term  rating
           from S&P, the unsecured,  unguaranteed and otherwise  unsupported  long-term senior
           debt  obligations  of  Party A  are rated "A" or below by S&P (such  event,  an S&P
           COLLATERALIZATION EVENT).

           RELEVANT  ENTITY  means Party A and any  guarantor  under an Eligible  Guarantee in
           respect of all of Party A's present and future obligations under this Agreement.

    (2) Without prejudice to Party A's obligations under the Collateral Support Annex,  during
        any period in which a Collateralization Event is occurring,  Party A shall, at its own
        expense and within thirty (30) Business  Days of such  Collateralization  Event (or 30
        calendar  days,  in the  case of an S&P  Collateralization  Event),  either  (i)  post
        collateral  according  to the  terms of the 1994  ISDA  Credit  Support  Annex to this
        Schedule,  including  Paragraph 13 thereof (the CREDIT SUPPORT ANNEX), (ii) furnish an
        Eligible  Guarantee (as defined below) of Party A's  obligations  under this Agreement
        that is (in the case of an S&P  Collateralization  Event) subject to the  satisfaction
        of the S&P Ratings  Condition from a guarantor  that satisfies the Hedge  Counterparty
        Ratings  Requirement (as defined  herein),  or (iii) obtain a substitute  counterparty
        (and provide  prior written  notice to each Rating  Agency with respect  thereto) that
        (a) is reasonably  acceptable to Party B, (b) satisfies the Hedge Counterparty Ratings
        Requirement and (c) assumes the  obligations of Party A under this Agreement  (through
        an assignment and assumption agreement in form and substance  reasonably  satisfactory
        to Party B) or replaces the outstanding  Transactions  hereunder with  transactions on
        identical terms, except that Party A shall be replaced as counterparty,  PROVIDED that
        such substitute counterparty,  as of the date of such assumption or replacement,  must
        not,  as a result  thereof,  be required to withhold or deduct on account of tax under
        the  Agreement  or the  new  transactions,  as  applicable,  and  such  assumption  or
        replacement  must not lead to a  termination  event or event of default  occurring  in
        respect of the new transactions,  as applicable,  PROVIDED FURTHER,  that (in the case
        of an S&P Collateralization  Event) satisfaction of the S&P Ratings Condition shall be
        required  for any transfer of any  Transactions  under this Part  5(b)(2)(iii)  unless
        such transfer is in connection  with the  assignment  and assumption of this Agreement
        by such substitute  counterparty  without  modification  of its terms,  other than the
        following  terms:  party name,  dates relevant to the effective date of such transfer,
        tax representations  (provided that the representations in Part 2(a) are not modified)
        and any other representations  regarding the status of the substitute  counterparty of
        the type  included  in  Section  (c) of this Part 5 and notice  information  (in which
        case,  Party A shall  provide  written  notice to S&P with  respect  thereto).  To the
        extent  that Party A elects or is required  to post  collateral  pursuant to this Part
        5(b)(1)  following  an S&P  Collateralization  Event,  Party A shall  deliver  to each
        Rating  Agency (with a copy to the Trustee)  within  thirty (30)  calendar days of the
        occurrence  of such  Collateralization  Event an opinion  acceptable  to S&P as to the
        enforceability  of the Credit Support Annex and which  confirms that,  notwithstanding
        the  commencement  of a case under the  Bankruptcy  Code with  respect to Party A, the
        collateral  will  (a) be  available  to  meet  swap  obligations  notwithstanding  the
        automatic  stay and (b) if delivered  pre-bankruptcy,  will not be subject to recovery
        as  preferences  or  constructive  fraudulent  conveyances,  in each case  subject  to
        standard qualifications and assumptions.

        ELIGIBLE  GUARANTEE means an unconditional and irrevocable  guarantee that is provided
        by a guarantor as principal  debtor rather than surety and is directly  enforceable by
        Party B, where 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
        withholding  for Tax or (B) such  guarantee  provides  that,  in the event that any of
        such  guarantor's  payments  to Party B are  subject  to  withholding  for  Tax,  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  withholding  tax)
        will equal the full amount Party B would have  received had no such  withholding  been
        required.

        An entity shall satisfy the HEDGE COUNTERPARTY  RATINGS  REQUIREMENT if (a) either (i)
        the unsecured,  unguaranteed and otherwise unsupported  short-term debt obligations of
        the  entity  are  rated at least  "A-1" by S&P or (ii) if the  entity  does not have a
        short-term  rating from S&P, the  unsecured,  unguaranteed  and otherwise  unsupported
        long-term  senior debt  obligations  of the entity are rated at least "A+" by S&P, (b)
        either (i) the unsecured,  unguaranteed  and otherwise  unsupported  long-term  senior
        debt  obligations of such entity are rated at least "A3" by Moody's and the unsecured,
        unguaranteed and otherwise unsupported  short-term debt obligations of such entity are
        rated at least "P-2" by Moody's (if such  entity has both a long-term  and  short-term
        rating from  Moody's) or (ii) if such  entity does not have a  short-term  debt rating
        from Moody's, the unsecured,  unguaranteed and otherwise  unsupported long-term senior
        debt  obligations of such entity are rated at least "A3" by Moody's and (c) either (i)
        the  unsecured,   unguaranteed  and  otherwise   unsupported   long-term  senior  debt
        obligations of such  substitute  counterparty  are rated at least "A" by Fitch or (ii)
        the unsecured,  unguaranteed and otherwise unsupported  short-term debt obligations of
        such  substitute  counterparty  are rated at least "F1" by Fitch.  For the  purpose of
        this definition,  no direct or indirect  recourse against one or more  shareholders of
        the entity (or  against any Person in control of, or  controlled  by, or under  common
        control  with,  any such  shareholder)  shall be deemed  to  constitute  a  guarantee,
        security or support of the obligations of the entity.

        S&P RATINGS  CONDITION shall mean prior written  confirmation from S&P that a proposed
        action will not cause the downgrade or  withdrawal of the then current  ratings of any
        outstanding Certificates.

        RATING AGENCY shall mean each of S&P, Moody's and Fitch

    (3) It shall be a ratings event  (RATINGS  EVENT) if at any time after the date hereof (A)
        so long as S&P is  currently  rating the  Certificates  and either (i) the  unsecured,
        unguaranteed  and otherwise  unsupported  long-term  senior debt  obligations  of each
        Relevant Entity are rated "BB+" or below by S&P, (ii) the unsecured,  unguaranteed and
        otherwise  unsupported  short-term debt  obligations of each Relevant Entity are rated
        "A3" or below by S&P or (iii) if at any time after the date hereof S&P  withdraws  all
        of each  Relevant  Entity's  ratings and no longer  rates any  Relevant  Entity  (such
        event,  an S&P  RATINGS  EVENT),  (B) so long  as  Moody's  is  currently  rating  the
        Certificates  and either (i) the  unsecured,  unguaranteed  and otherwise  unsupported
        long-term  senior debt obligations of each Relevant Entity are unrated or rated "Baa1"
        or below by Moody's (or such rating is withdrawn) or (ii) the unsecured,  unguaranteed
        and otherwise  unsupported  short-term  debt  obligations of each Relevant  Entity are
        unrated or rated "P-3" or below by Moody's (or such rating is withdrawn)  (such event,
        a MOODY'S RATINGS EVENT) or (C) so long as Fitch is currently  rating the Certificates
        and either (i) the unsecured,  unguaranteed and otherwise unsupported long-term senior
        debt  obligations of each Relevant Entity are rated below "BBB+" by Fitch, or (ii) the
        unsecured,  unguaranteed and otherwise unsupported short-term debt obligations of each
        Relevant Entity are rated below "F2" by Fitch (such event, a FITCH RATINGS EVENT).

     (4)       Following a Ratings Event, Party A shall take the following actions:

           (a) in the case of an S&P Ratings Event,  Party A,  at its sole expense,  shall (i)
           within  10  Business  Days,  subject  to  extension  upon  satisfaction  of the S&P
           Ratings  Condition,  of the Ratings Event,  obtain a substitute  counterparty  (and
           provide  written  notice to each Rating  Agency  with  respect  thereto),  that (A)
           satisfies  the  Hedge  Counterparty   Ratings   Requirement  and  (B)  assumes  the
           obligations of Party A under this  Agreement  (through an assignment and assumption
           agreement in form and  substance  reasonably  satisfactory  to Party B) or replaces
           the  outstanding  Transactions  hereunder  with  transactions  on identical  terms,
           except  that  Party A  shall  be  replaced  as  counterparty,  PROVIDED  that  such
           substitute  counterparty,  as of the date of such assumption or  replacement,  must
           not,  as a result  thereof,  be  required  to  withhold or deduct on account of tax
           under the Agreement or the new  transactions,  as applicable,  and such  assumption
           or replacement must not lead to a termination  event or event of default  occurring
           in  respect  of  the  new  transactions,  as  applicable;   PROVIDED  FURTHER  that
           satisfaction  of the  S&P  Ratings  Condition  shall  be  required  within  such 10
           Business  Days  or  longer  period,   as  applicable,   for  any  transfer  of  any
           Transaction  under this clause (a)(i)  unless such  transfer is in connection  with
           the assignment and assumption of this Agreement  without  modification of its terms
           by such  counterparty,  other than the following terms:  party name, dates relevant
           to the effective  date of such  transfer,  tax  representations  (provided that the
           representations  in Part  2(a)  are not  modified)  and any  other  representations
           regarding  the  status  of the  substitute  counterparty  of the type  included  in
           Section (c) of this Part 5 and notice  information  (in which  case,  Party A shall
           provide  prior  written  notice to S&P and the Trustee  with  respect  thereto) and
           (ii) post collateral according to the terms of the Credit Support Annex; and

           (b) in the case of a Moody's  Ratings Event or a Fitch Ratings Event,  Party A,  at
           its sole  expense,  shall (i) use  commercially  reasonable  efforts to, as soon as
           reasonably   practicable,   (A)  furnish  an  Eligible   Guarantee   of  Party  A's
           obligations  under this Agreement from a guarantor that satisfies  paragraph (b) of
           the  definition  of  Hedge  Counterparty   Ratings  Requirement  or  (B)  obtain  a
           substitute  counterparty  (and provide prior  written  notice to each Rating Agency
           with respect  thereto) that (1) is reasonably  acceptable to Party B, (2) satisfies
           the paragraph (b) of the definition of Hedge Counterparty  Ratings  Requirement and
           (3)  assumes  the  obligations  of  Party  A  under  this  Agreement   (through  an
           assignment and assumption agreement in form and substance  reasonably  satisfactory
           to Party B) or replaces the outstanding  Transactions  hereunder with  transactions
           on  substantially  the  same  terms,  including  rating  triggers,  credit  support
           documentation  and other  provisions of this  Agreement,  except that Party A shall
           be replaced as  counterparty,  PROVIDED that such  substitute  counterparty,  as of
           the date of such  assumption  or  replacement,  must not, as a result  thereof,  be
           required  to withhold  or deduct on account of tax under the  Agreement  or the new
           transactions,  as applicable,  and such assumption or replacement  must not lead to
           a  termination  event  or  event  of  default  occurring  in  respect  of  the  new
           transactions,  as  applicable  and (ii) post  collateral  according to the terms of
           the Credit Support Annex.

           RATING AGENCY APPROVAL shall mean prior written confirmation from S&P and Moody's
           that such action will not cause them to downgrade or withdraw its then-current
           ratings of any outstanding Certificates.

(c) Section  3(a) of this  Agreement  is hereby  amended to include the  following  additional
    representations after paragraph 3(a)(v):

    (vi) ELIGIBLE CONTRACT PARTICIPANT.  It is an "eligible contract participant" as such term
    is defined in Section 35.1 (b) (2) of the  regulations (17 C.F.R.  35)  promulgated  under
    and as defined in Section 1a(12) of the U.S. Commodity Exchange Act, as amended.

    (vii) INDIVIDUAL NEGOTIATION.  This Agreement and each Transaction hereunder is subject to
    individual negotiation by the parties.

    (viii)  RELATIONSHIP  BETWEEN PARTY A AND PARTY B. Subject as provided in Part 5(f),  each
    of Party A and Party B will be deemed  to  represent  to the other on the date on which it
    enters  into a  Transaction  or an  amendment  thereof  that  (absent a written  agreement
    between  Party  A and  Party  B that  expressly  imposes  affirmative  obligations  to the
    contrary for that Transaction):

        (1)    CAPACITY.  Party A  represents  to Party B on the date on which  Party A enters
        into this  Agreement  that it is entering into the Agreement  and the  Transaction  as
        principal  and not as agent of any person.  Party B represents  to Party A on the date
        on which  Party B enters this  Agreement  it is entering  into the  Agreement  and the
        Transaction not in its individual  capacity but solely in its capacity as Supplemental
        Interest Trustee.

        (2)    NON-RELIANCE.  Party A is acting for its own account and with  respect to Party
        B, the Trustee is executing this Agreement as  supplemental  interest trust trustee on
        behalf of the Trust.  Each party has made its own independent  decisions to enter into
        that  Transaction  and as to whether that  Transaction is appropriate or proper for it
        based  upon its own  judgment  and upon  advice  from such  advisors  as it has deemed
        necessary.  It is not  relying  on any  communication  (written  or oral) of the other
        party as investment advice or as a recommendation  to enter into that Transaction;  it
        being  understood  that  information  and  explanations   related  to  the  terms  and
        conditions  of  a  Transaction  shall  not  be  considered   investment  advice  or  a
        recommendation  to enter into that  Transaction.  No  communication  (written or oral)
        received  from the other party shall be deemed to be an  assurance  or guarantee as to
        the expected results of that Transaction.  Notwithstanding the foregoing,  in the case
        of the Trustee, it has been directed by the PSA to enter into this Transaction.

        (3)    EVALUATION AND  UNDERSTANDING.  It is capable of evaluating  and  understanding
        (on its own behalf or through independent  professional  advice),  and understands and
        accepts,  the  terms,  conditions  and risks of this  Agreement  and each  Transaction
        hereunder.  It is also capable of assuming, and assumes, all financial and other risks
        of this Agreement and each Transaction  hereunder.  Notwithstanding the foregoing,  in
        the  case  of the  Trustee,  it has  been  directed  by the  PSA to  enter  into  this
        Transaction.

        (4)    STATUS OF PARTIES.  The other party is not acting as a fiduciary  or an advisor
        for it in respect of that Transaction.

(d)  Section 4 is hereby amended by adding the following new agreement:

    ACTIONS AFFECTING  REPRESENTATIONS.  Party B agrees not to take any action during the term
    of this  Agreement or any  Transaction  hereunder  that renders or could render any of the
    representations and warranties in this Agreement untrue,  incorrect,  or incomplete,  and,
    if any event or  condition  occurs that  renders or could  render any such  representation
    untrue, incorrect, or incomplete,  Party B will immediately give written notice thereof to
    Party A.

(e) TRANSFER.

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

        Except as stated under Section  6(b)(ii),  provided that to the extent Party A makes a
        transfer  pursuant to Section  6(b)(ii) it will provide a prior written  notice to the
        Rating Agencies of such transfer,  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) Party A may transfer this  Agreement to any Person that is an office,  branch
        or affiliate of Party A (any such Person,  office, branch or affiliate,  a TRANSFEREE)
        on at least five Business Days' prior written  notice to Party B; 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.  Notwithstanding  the  foregoing,  no  transfer  shall  be made  unless  the
        transferring party obtains a written  acknowledgment  from each of the Rating Agencies
        that,  notwithstanding  such transfer,  the  then-current  ratings of the Certificates
        will not be reduced or withdrawn,  PROVIDED,  HOWEVER,  that this provision  shall not
        apply to any transfer  that is made  pursuant to the  provisions  of Part 5(b) of this
        Agreement.

        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 written consent of
        the  Trustee  on  behalf  of  Party B but with  prior  written  notice  to S&P and the
        Trustee,  to an Affiliate of Party A that (i) satisfies the Hedge Counterparty  Rating
        Requirements or that has furnished a guarantee,  subject to S&P Ratings Condition,  of
        the  obligations  under this  Agreement  from a  guarantor  that  satisfies  the Hedge
        Counterparty  Rating  Requirements  and  (ii) as of the  date of  such  transfer  such
        Affiliate  will not be  required  to  withhold  or deduct on account of a Tax from any
        payments under this Agreement  unless such Affiliate will be required to make payments
        of additional  amounts pursuant to Section  2(d)(i)(4) of this Agreement in respect of
        such Tax;  provided that  satisfaction  of the S&P Ratings  Condition will be required
        unless such  transfer is in  connection  with the  assignment  and  assumption of this
        Agreement  by such an  Affiliate  without  modification  of its terms,  other than the
        following  terms:  party name,  dates relevant to the effective date of such transfer,
        tax representations  (provided that the representations in Part 2(a) are not modified)
        and  any  other  representations  regarding  the  status  of  such  an  Affiliate  the
        substitute  counterparty of the type included in Section (c) of this Part 5 and notice
        information  (in which case,  Party A shall provide written notice to S&P with respect
        thereto).

    (ii)        If an Eligible  Replacement  has made a Firm Offer  (which means 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 in accordance with
        the PSA to effect such transfer.

    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

    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(j) shall not  constitute  an Event of  Default  or a  Termination
    Event.

    application thereof to any party or circumstance,  shall be held to be illegal, invalid or
    unenforceable  (in whole or in part) for any  reason,  the  remaining  terms,  provisions,
    covenants  and  conditions  hereof  shall  continue  in full  force and  effect as if this
    Agreement  had  been  executed  with  the  illegal,   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 to this Agreement.

(s) ESCROW  PAYMENTS.  If  (whether  by reason of the time  difference  between  the cities in
    which  payments  or  deliveries  are to be  made  or  otherwise)  it is not  possible  for
    simultaneous  payments  or  deliveries  to be made on any date on which both  parties  are
    required to make payments or deliveries  hereunder,  either party may at its option and in
    its  sole   discretion   notify  the  other  party   (Section   2(b)  of  this   Agreement
    notwithstanding)  that  payments or deliveries on that date are to be made in escrow (such
    party  being the  "Appointing  Party").  In this case,  deposit of the payment or delivery
    due  earlier on that date will be made by 2.00 pm (local time at the place for the earlier
    payment or delivery) on that date with an escrow agent selected by the  Appointing  Party,
    accompanied by irrevocable  payment or delivery  instructions (i) to release the deposited
    payment or delivery to the  intended  recipient  upon  receipt by the escrow  agent of the
    required  deposit of the  corresponding  payment or  delivery  from the other party on the
    same date accompanied by irrevocable payment or delivery  instructions to the same effect,
    or (ii) if the required  deposit of the  corresponding  payment or delivery is not made on
    that same date,  to return the  payment or  delivery  deposited  to the party that paid or
    delivered  it into  escrow.  The  Appointing  Party  will  pay  all  costs  of the  escrow
    arrangements.  The  Appointing  Party  will bear the risk of any  failure of the [bank] it
    nominates  to be its escrow agent to fully and promptly  perform the  obligations  of such
    escrow agent as  contemplated  in this Part 5(s) Any amounts  payable or  deliveries to be
    made under this  Agreement  by the  Appointing  Party which are not  received by the other
    party  hereto on the due date will remain due and payable or to be made by the  Appointing
    Party as of such date  (assuming  timely  payment or  delivery  on the due date of amounts
    payable or  deliveries  to be made by the other party  hereto).  Any amounts or deliveries
    due from the other  party,  which  have  been paid or  delivered  to the  escrow  agent in
    accordance with this Part 5(s) (and any instructions in connection  therewith given to the
    other party by the Appointing  Party) shall be treated as having been paid or delivered by
    such other party and  received by the  Appointing  Party as of the date on which they were
    paid or delivered to the  Appointing  Party's  escrow agent.  The  Appointing  Party shall
    cause the escrow  arrangements  to  provide  that the other  party  shall be  entitled  to
    interest  on any  payment  due to be  deposited  first  for each day in the  period of its
    deposit at the rate  offered by the escrow  agent for that day for  overnight  deposits in
    the relevant  currency in the office where it holds that deposited  payment (at 11:00 a.m.
    local time on that day) if that  payment is not  released  by to the other party 5:00 p.m.
    local time on the date it is deposited for any reason other than the intended  recipient's
    failure  to make the escrow  deposit it is  required  to make  under this  paragraph  in a
    timely fashion..

    is required  under  Regulation AB as a result of the aggregate  "significance  percentage"
    exceeding 10%) (the SWAP FINANCIAL DISCLOSURE).

    (iii)      Upon the occurrence of a Swap  Disclosure  Event,  Party A, at its own expense,

    Part 5 and notice  information (in which case, Party A shall provide written notice to S&P

    1115 of Regulation  AB, such that  disclosure  provided in respect of the  affiliate  will
    satisfy any  disclosure  requirements  applicable  with respect to the  Counterparty,  and
    cause such  affiliate to provide Swap  Financial  Disclosure.  If permitted by  Regulation
    AB, any required Swap Financial  Disclosure may be provided by  incorporation by reference
    from reports filed pursuant to the Exchange Act.

    in relation to payments by Party B, no Tax shall be an  Indemnifiable  Tax. The provisions
    of Section  2(d)(ii) of this Agreement  shall not apply to Party B such that Party B shall
    not be required to pay any additional amounts referred to therein.

(x) CALCULATIONS.  Notwithstanding  Section 6 of this Agreement, so long as Party A is (A) the
sole    Affected  Party  (other  than  pursuant  to an  Illegality  or a Tax Event) or (B) the
Defaulting Party in   respect of any Event of  Default,  paragraphs  (i) to (vii)  below shall

     B (expressed as a positive number) in  consideration of an agreement  between Party B and
     such 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  Transactions  or group of  Terminated
     Transactions  that would, but for the occurrence of the relevant Early  Termination Date,
     have been required  after that date, (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  and (4)  made in  respect  of a
     Replacement  Transaction  with terms  substantially  the same as those of this  Agreement
     (save for the exclusion of provisions  relating to  Transactions  that are not Terminated
     Transactions)."

(ii)    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 (as
     determined by Party B based on information provided by the Reference  Market-Maker) equal
     to the Termination  Currency  Equivalent of the amount (whether  positive or negative) of
     any Market  Quotation  for the relevant  Terminated  Transaction  or group of  Terminated
     Transactions  that is  accepted  by Party B in  accordance  with the PSA so as to  become
     legally binding, provided that:

     (1)   If, on 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 in  accordance  with
           the PSA may  specify in  writing  to Party A (but in either  case no later than the
           Early  Termination  Date) (such day 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 in  accordance  with the PSA
           so as to become legally  binding and one or more Market  Quotations  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); and

     (2)   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 in  accordance  with the PSA so as to become  legally  binding
           and no Market  Quotations  have been made and remain  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.

(iii)   For the purpose of clause (4) of the  definition  of Market  Quotation,  Party B shall
    determine in  accordance  with the PSA,  based on  information  provided by the  Reference
    Market-Maker,  whether a Live Bid is made in respect  of a  Replacement  Transaction  with
    commercial  terms  substantially  the  same as  those  of  this  Agreement  (save  for the
    exclusion of provisions relating to Transactions that are not Terminated Transactions).

(iv)    At any time on or before the Latest Settlement  Amount  Determination Day at which two
    or more Market  Quotations  remain capable of becoming  legally  binding upon  acceptance,
    Party B shall be entitled to accept  only 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).

(v)     If Party B in  accordance  with the PSA requests  Party A in writing to obtain  Market
    Quotations,  Party  A  shall  use  its  reasonable  efforts  to do so  before  the  Latest
    Settlement Amount Determination Day.

(vi)    If the Settlement  Amount is a negative number,  Section  6(e)(i)(3) of this Agreement
    shall be deleted in its entirety and replaced with the following:

     "SECOND METHOD AND MARKET  QUOTATION.  If Second Method and Market  Quotation  apply, (1)
     Party B shall  pay to Party A an amount  equal to the  absolute  value of the  Settlement
     Amount in respect of the  Terminated  Transactions,  (2) Party B shall pay to Party A the

               (b) the highest quotation for a Reference Market-maker,  if applicable, for the
               next Valuation Date;  provided,  that this Paragraph 13(l)(ix) shall only apply
               to the extent  that the  Certificates  outstanding  at such time (as defined in
               the PSA) are  rated  higher  by S&P  than  the S&P L-T  Rating  of Party A; and
               provided   further,   that  Party  A  shall  not  seek   verification   of  its
               determination   of  Exposure  as  described   above  from  the  same  Reference
               Market-maker  more than four times in any  twelve-month  period.  Party A shall

               any agent or custodian  for  safekeeping  of the Secured Party ) to the Pledgor
