                                                                          and         Supplemental Interest Trust created under the Pooling and Servicing

               _______________________________________                                            _________________________________________
                             ("Party A")                                                                         ("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.

         (i)      Status.  It is duly  organised and validly  existing  under the laws of the  jurisdiction  of its
         organisation or incorporation and, if relevant under such laws, in good standing;

         (ii)     Powers.  It has the power to execute  this  Agreement  and any other  documentation  relating  to
         this Agreement to which it is a party, to deliver this Agreement and any other  documentation  relating to
         this  Agreement  that it is required by this  Agreement  to deliver and to perform its  obligations  under
         this Agreement and any  obligations  it has under any Credit  Support  Document to which it is a party and
         has taken all necessary 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 its  constitutional  documents,  any order or judgment of
         any  court  or other  agency  of  government  applicable  to it or any of its  assets  or any  contractual
         restriction binding on or affecting it or any of its assets;

         (iv)     Consents.  All  governmental  and other  consents  that are required to have been  obtained by it

         and are in full force and effect and all conditions of any such consents have been complied with; and

         (v)      Obligations  Binding.  Its  obligations  under this Agreement and any 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  entering  into or  performing  its  obligations  under this  Agreement  or any  Credit  Support
Document to which it is a party.

(c)      Absence of  Litigation.  There is not pending or, to its  knowledge,  threatened  against it or any of its
Affiliates any action,  suit or proceeding at law or in equity or before any court,  tribunal,  governmental  body,
agency or official or any arbitrator that is likely to affect the legality,  validity or enforceability  against it
of this Agreement or any Credit Support  Document to which it is a party or its ability to perform its  obligations
under this Agreement or such Credit Support Document.

(d)      Accuracy of  Specified  Information.  All  applicable  information  that is  furnished in writing by or on
behalf of it to the other party and is  identified  for the purpose of this  Section 3(d) in the Schedule is, as of
the date of the information, true, accurate and complete in every material respect.

(e)      Payer Tax  Representation.  Each  representation  specified  in the  Schedule  as being made by it for the
purpose of this Section 3(e) is accurate and true.

Agreement or under any Credit Support Document to which it is a party:-

(a)      Furnish  Specified  Information.  It  will  deliver  to  the  other  party  or,  in  certain  cases  under

         (iii) upon  reasonable  demand  by such  other  party,  any  form or  document  that  may be  required  or
         reasonably  requested  in writing in order to allow such other  party or its Credit  Support  Provider  to
         make a payment under this 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,

in each case by the date  specified  in the  Schedule or such  Confirmation  or, if none is  specified,  as soon as
reasonably practicable.

(b)      Maintain  Authorisations.  It will use all  reasonable  efforts to  maintain  in full force and effect all
consents of any  governmental  or other  authority  that are  required  to be  obtained by it with  respect to this

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.

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

              consent of the other party; or

                  (3) the party or such Credit Support Provider  disaffirms,  disclaims,  repudiates or rejects, in

               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)(1),  (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)(1) 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 he entered into as soon
         as practicable  and may he 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 re-enactment  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

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

under Section 11. A party will  determine its Loss as of the relevant  Early  Termination  Date, or, if that is not
reasonably  practicable,  as of the earliest date  thereafter as is reasonably  practicable.  A party may (but need
not)  determine its Loss by reference to quotations  of 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, havebeen 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.

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,

"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.

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

"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

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

     (1) It shall be a collateralization event (Collateralization Event) if:

              (A) with  respect to each  Relevant  Entity,  so long as  Moody's  Investors  Service,  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

              (B) Reserved;

              (C)  with  respect  to each  Relevant  Entity,  if  such  entity  is a bank,  broker/dealer,
              insurance  company,  structured  investment  vehicle or derivative product company (any such
              entity, a Financial  Institution),  so long as Standard & Poor's Rating Services, a division

              (i) the unsecured,  unguaranteed  and otherwise  unsupported  short-term debt obligations of
              such Relevant  Entity are rated "A-2" by S&P or (ii) if such Relevant Entity does not have a

     (2) Without prejudice to Party A's obligations  under the Credit Support Annex,  during any period in
         which  a  Collateralization  Event  is  occurring,  Party A  shall,  at  its  own  expense,  post
         collateral  according  to the  terms of the 1994  ISDA  Credit  Support  Annex to this  Schedule,
         including  Paragraph 13 thereof  (the Credit  Support  Annex).  To avoid the  obligation  to post
         collateral  in  accordance  with the CSA,  Party A may,  at any time,  (i)  furnish  an  Eligible
         Guarantee  (as defined  below) of Party A's  obligations  under this  Agreement  from a guarantor
         that satisfies the Hedge  Counterparty  Ratings  Requirement (as defined  herein),  (ii) 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 Rating  Agency  Condition  in
         relation  to S&P  shall  be  required  for any  transfer  of any  Transactions  under  this  Part
         5(b)(2)(ii)  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)  or (iii) in the case of an S&P  Collateralization  Event,
         perform any other action which satisfies the Rating Agency Condition in relation to S&P.

         Eligible  Guarantee  means an  unconditional  and  irrevocable  guarantee  that is  provided by a
         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  with
         respect to each relevant Rating Agency other than Moody's,  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  deduction  or  withholding  for Tax and  such  opinion  has been
         delivered  to  Moody's,  (B)  such  guarantee  provides  that,  in the  event  that  any of  such
         guarantor's  payments to Party B are subject to deduction or 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 tax) will  equal the full  amount  Party B
         would have received had no such deduction or  withholding  been required or (C) in the event that
         any payment  under such  guarantee is made net of deduction or  withholding  for Tax,  Party A is
         required,  under Section 2(a)(i),  to make such additional payment as is necessary to ensure that
         the net amount  actually  received by Party B from the  guarantor and Party A will equal the full
         amount Party B would have received had no such deduction or withholding been required.

         An entity  shall  satisfy the Hedge  Counterparty  Ratings  Requirement  if (a) either (i) if the
         entity  is a  Financial  Institution,  the  unsecured,  unguaranteed  and  otherwise  unsupported
         short-term  debt  obligations  of the  entity  are rated at least  "A-2" by S&P or, if the entity
         does not have a short-term  unsecured  and  unsubordinated  debt rating from S&P, the  unsecured,
         unguaranteed  and  otherwise  unsupported  long-term  senior debt  obligations  of the entity are
         rated  at  least  "BBB+"  by S&P,  or  (ii) if such  entity  is not a  Financial  Institution,  a
         short-term  unsecured and  unsubordinated  debt rating of "A-1" from S&P, or, if such entity does
         not have a short-term  unsecured and unsubordinated  debt rating from S&P, a long-term  unsecured
         and  unsubordinated  debt rating or counterparty  rating of "A+" from S&P; and (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.  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.

         Rating Agency shall mean each of S&P and Moody's.

         Rating Agency  Condition  means,  with respect to any particular  proposed act or omission to act
         hereunder  and each Rating  Agency  specified in  connection  with such proposed act or omission,
         that the party acting or failing to act must consult with each of the specified  Rating  Agencies
         and receive from each such Rating Agency a prior written  confirmation  that the proposed  action
         or  inaction  would  not  cause a  downgrade  or  withdrawal  of the  then-current  rating of any
         Relevant Securities.

     (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) if the Relevant  Entity is a Financial
         Institution,  the  unsecured,  unguaranteed  and  otherwise  unsupported  long-term  senior  debt
         obligations  of each  Relevant  Entity are rated  "BBB" or below by S&P or,  (ii) the  unsecured,
         unguaranteed  and otherwise  unsupported  short-term debt obligations of each Relevant Entity are
         rated  "A-3" or below by S&P (ii) if the  Relevant  Entity is not a  Financial  Institution,  the
         unsecured and  unsubordinated  short-term  debt  obligations  of each  Relevant  Entity are rated
         "A-2"  or  below  from  S&P,  or,  if such  entity  does  not  have a  short-term  unsecured  and
         unsubordinated   debt  rating  from  S&P,  the  long-term   unsecured  and  unsubordinated   debt
         obligations  are rated  "A" 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).

              relation to S&P, of the Ratings  Event,  either (x) 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 Rating
              Agency  Condition  in  relation to S&P shall be  required  within  such 60 calendar  days or
              longer  period,  as  applicable,  for any  transfer  of any  Transaction  under this  clause
              (a)(i)(x)  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  Supplemental  Interest  Trust  Trustee  with
              respect  thereto),  (y) furnish an Eligible  Guarantee of Party A's  obligations  under this
              Agreement  from  a  guarantor  that  satisfies  paragraph  (a) of the  definition  of  Hedge
              Counterparty  Ratings Requirement or (z) perform any other action which satisfies the Rating
              Agency  Condition in relation to S&P and (ii) post collateral  according to the terms of the
              Credit Support Annex; and

              (b) in the case of a  Moody's  Ratings  Event,  Party A,  at its  sole  expense,  shall  use
              commercially  reasonable efforts to (i), 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.
              Party A's failure to post collateral  pursuant to Part  5(b)(4)(b)(ii)  shall  constitute an
              Event of Default  with Party A as the sole  Affected  Party.  Party A's  failure to act in a
              commercially  reasonable manner pursuant to Part 5(b)(4)(b)(i)  shall constitute a Breach of
              Agreement under Section 5(a)(ii).

(c)  Section  3(a)  of  this   Agreement   is  hereby   amended  to  include  the   following   additional

         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.

         (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.

         (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 upon obtaining  actual  knowledge of such
     action.

(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

         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,

         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

         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.  Notwithstanding  the foregoing,  no
         transfer shall be made unless the transferring party obtains a written  acknowledgment  from each
         of the Rating Agencies other than Moody's 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 Party B
         but  with  prior  written  notice  to S&P and the  Supplemental  Interest  Trust  Trustee,  to an
         Affiliate of Party A that (i) satisfies the Hedge  Counterparty  Rating  Requirements or that has
         furnished  a  guarantee,  subject  to  Rating  Agency  Condition  in  relation  to  S&P,  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 Rating
         Agency  Condition in relation to S&P 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  Section  7 and  notice
         information (in which case, Party A shall provide written notice to S&P with respect thereto).

         Party B will execute such  documentation  as is  reasonably  deemed  necessary by Party A for the
         effectuation of any transfer under this Section 7."

     (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 transfer under
         Part  5(b),  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.

(f)  Supplemental  Interest Trust Trustee 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.  (the

     binding only the  Supplemental  Interest Trust,  (iii) nothing herein contained shall be construed as
     creating any  liability on the part of the  Supplemental  Interest  Trust  Trustee,  individually  or
     personally,  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 the Supplemental  Interest
     Trust  Trustee  be  personally  liable  for  the  payment  of any  indebtedness  or  expenses  of the
     Supplemental   Interest   Trust  or  be  liable  for  the  breach  or  failure  of  any   obligation,
     representation,  warranty or covenant  made or undertaken by the  Supplemental  Interest  Trust under
     this  Agreement or any other  related  documents as to all of which  recourse  shall be had solely to
     the assets of the Supplemental Interest Trust in accordance with the terms of the PSA.

(g)  Proceedings.  No Relevant  Entity  shall  institute  against,  or cause any other person to institute

     or similar law, for a period of one year and one day, or if longer the applicable  preference  period
     then in  effect,  following  payment  in full of the  Certificates.  Nothing  shall  preclude,  or be
     deemed to stop,  a  Relevant  Entity  (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 the trust,  as
     applicable or (B) any  involuntary  insolvency  proceeding  filed or commenced by a Person other than
     Party A, (ii) from  commencing  against  Party B or any of the Mortgage  Loans any legal action which
     is not a bankruptcy,  reorganization,  arrangement,  insolvency,  moratorium,  liquidation or similar
     proceeding or (iii) from taking any action (not  otherwise  mentioned in this  paragraph)  which will
     prevent an impairment of any right  afforded to it under the PSA as a third party  beneficiary.  This
     provision shall survive termination of this Agreement.

(h)  Change  of  Account.  Section  2(b) of this  Agreement  is  hereby  amended  by the  addition  of the

     consent  of  Party  A (such  consent  not to be  unreasonably  withheld)  to any  such  amendment  or
     modification:  (x)  where  such  consent  is  required  under  the  terms of the PSA;  or (y) if such
     amendment or modification  would: (i) adversely  affect any of Party A's rights or obligations  under

     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

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

(l)  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,

     solely from the Supplemental  Interest Trust assets,  in accordance with the terms of the PSA. In the
     event that the  Supplemental  Interest  Trust  assets  should be  insufficient  to satisfy all claims
     outstanding  and following the  realization of the  Supplemental  Interest  Trust assets,  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  Supplemental
     Interest  Trust  Trustee  shall  not have  liability  for any  failure  or delay in  making a payment

(p)  Reserved.
(q)  Waiver of Jury Trial.  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  certifies (i) 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.

     trading  and  marketing  personnel  of the  parties  and their  Affiliates  in  connection  with this
     Agreement  or any  potential  transaction  and (ii) if  applicable,  agrees to obtain  any  necessary
     consent of, and give notice of such recording to, such personnel of it and its Affiliates.

(s)  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  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.

(t)  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(t) 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(t) (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..

(u)  Compliance with Regulation AB.

     (i) Party A agrees and  acknowledges  that Depositor  ("Depositor")  is required under  Regulation AB
     under the  Securities Act of 1933, as amended,  and the  Securities  Exchange Act of 1934, as amended
     (the "Exchange Act")  ("Regulation  AB"), to disclose  certain  information  regarding Party A or its
     group of affiliated entities,  if applicable,  depending on the aggregate  "significance  percentage"
     under 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)It shall be a swap  disclosure  event  ("Swap  Disclosure  Event") if, on any Business Day during
     the term of the Transaction  hereunder,  Depositor  requests (in writing) from Party A the applicable
     financial  information  described  in Item  1115 of  Regulation  AB  (such  request  to be based on a
     reasonable  determination  by  Depositor,  in good faith,  that such  information  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,  shall (a)
     provide to Depositor the Swap Financial  Disclosure,  (b) secure another entity to replace Party A as
     party to this  Agreement  on terms  substantially  similar  to this  Agreement  and  subject to prior
     notification to the Rating Agencies,  provided,  that  satisfaction of the Rating Agency Condition in
     relation  to S&P shall be  required  for any  transfer of any  Transactions  under this clause  (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),  which
     entity (or a guarantor  therefor)  meets or exceeds the Hedge  Counterparty  Ratings  Requirement and
     which entity is able to comply with the financial  information  disclosure  requirements of Item 1115
     of Regulation AB or (c) obtain a guaranty of the Party A's  obligations  under this Agreement from an
     affiliate  of the  Party  A that  is  able  to  comply  with  the  financial  information  disclosure
     requirements  of Item 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.

(v)  Third Party Beneficiary.

     Depositor  shall be an express third party  beneficiary of this Agreement as if a party hereto to the
     extent of the Depositor's rights explicitly specified herein.

(w)  Credit Support  Default.  Section  5(a)(iii)(1) of this Agreement is hereby deleted and replaced with

     Default is continuing after any applicable grace period has elapsed;"

(x)  Tax.  Notwithstanding  the  definition of  "Indemnifiable  Tax" in Section 14 of this  Agreement,  in
     relation to payments by Party A, any Tax shall be an  Indemnifiable  Tax and, in relation to payments
     by Party B, no Tax shall be an Indemnifiable Tax.

(y)  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 Tax Event) or (B) the  Defaulting  Party in
respect of any Event of Default, Market Quotation and paragraphs (i) to (vii) below will apply:

     (i)      The definition of "Market  Quotation" shall be deleted in its entirety and replaced with the
     following:

           ""Market  Quotation" means, with respect to one or more Terminated  Transactions,  a Firm Offer
           (which may be solicited by either Party A or Party B) which is:

           (1)    made by a Reference Market-maker that is an Eligible Replacement;

           (2)    for an amount  that  would be paid to Party B  (expressed  as a  negative  number) or by
           Party B (expressed as a positive number) in  consideration of an agreement  between Party B and
           such Reference  Market-maker (which agreement includes an indemnification  agreement reasonably
           acceptable to the Depositor) to enter into a transaction (the "Replacement  Transaction")  that
           would have the effect of  preserving  for Party B 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 this Agreement 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  that are,  in all  material
           respects,  no less  beneficial for Party B than those of this Agreement (save for the exclusion
           of provisions  relating to Transactions  that are not Terminated  Transactions),  as determined
           by Party B."

     (ii)     In determining  whether or not a Firm Offer satisfies the condition in sub-paragraph  (4) of
     Market Quotation, Party B shall act in a commercially reasonable manner.

     (iii)    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:

           (1)    if, on or prior to such Early  Termination  Date,  a Market  Quotation  for the relevant
           Terminated  Transaction  or group of  Terminated  Transactions  is  accepted  by Party B or the
           Depositor  (on  its  behalf)  so  as  to  become  legally  binding,  the  Termination  Currency
           Equivalent of the amount (whether positive or negative) of such Market Quotation;

           (2)    if, on such Early  Termination  Date, no Market  Quotation  for the relevant  Terminated
           Transaction or group of Terminated  Transactions  has been accepted by Party B or the Depositor
           (on its behalf) so as to become  legally  binding and one or more Market  Quotations  have been
           communicated  to Party B or the  Depositor  (on its  behalf)  and remain  capable  of  becoming
           legally  binding upon  acceptance by Party B or the Depositor (on its behalf),  the Termination
           Currency  Equivalent of the amount (whether  positive or negative) of the lowest of such Market
           Quotations (for the avoidance of doubt, (i) a Market  Quotation  expressed as a negative number
           is lower  than a Market  Quotation  expressed  as a  positive  number and (ii) the lower of two
           Market  Quotations  expressed as negative  numbers is the one with the largest absolute value);
           or

           (3)    if, on such Early  Termination  Date, no Market  Quotation  for the relevant  Terminated
           Transaction  or group of  Terminated  Transactions  is accepted by Party B or the Depositor (on
           its behalf) so as to become legally  binding and no Market  Quotations  have been  communicated
           to Party B or the  Depositor  (on its behalf) and remain  capable of becoming  legally  binding
           upon acceptance by Party B or the Depositor (on its behalf),  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."

     (iv)     At any time on or before the Early  Termination Date at which two or more Market  Quotations
     have been  communicated  to Party B or the Depositor  (on its behalf) and remain  capable of becoming
     legally  binding  upon  acceptance  by  Party  B or the  Depositor  (on its  behalf),  Party B or the
     Depositor  (on its behalf)  shall be  entitled  to accept  only the lowest of such Market  Quotations
     (for the avoidance of doubt,  (i) a Market  Quotation  expressed as a negative number is lower than a
     Market  Quotation  expressed  as a  positive  number  and (ii) the  lower  of two  Market  Quotations
     expressed as negative numbers is the one with the largest absolute value).

     (v)      If Party B or the  Depositor  (on its behalf)  requests  Party A in writing to obtain Market
     Quotations, Party A shall use reasonable efforts to do so before the Early Termination Date.

     (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 Termination  Currency Equivalent
      of the  Unpaid  Amounts  owing  to  Party A and (3)  Party A shall  pay to  Party B the  Termination
      Currency  Equivalent of the Unpaid Amounts owing to Party B; provided that, (i) the amounts  payable
      under (2) and (3) shall be subject to netting in  accordance  with  Section  2(c) of this  Agreement
      and (ii)  notwithstanding  any other  provision  of this  Agreement,  any amount  payable by Party A
      under (3) shall not be netted against any amount payable by Party B under (1)."

     (vii)    For purposes of this Part 5(y),

      "Eligible  Replacement"  means an entity (A) satisfying the Hedge Counterparty  Ratings  Requirement
      or (B)  whose  present  and  future  obligations  owing  to  Party B are  guaranteed  pursuant  to a
      guarantee provided by a guarantor satisfying the Hedge Counterparty Ratings Requirements.

      "Firm  Offer"  means an offer  which,  when made,  was  capable of  becoming  legally  binding  upon
      acceptance.

(z)  Rating Agency  Notifications.  Notwithstanding any other provision of this Agreement,  this Agreement
     shall not be amended,  no Early  Termination Date shall be effectively  designated by Party B, and no
     transfer of any rights or obligations  under this  Agreement  shall be made (other than a transfer of
     all of Party A's rights and  obligations  with respect to this Agreement in accordance with Part 5(e)
     above) unless each Rating Agency has been given prior written notice of such  amendment,  designation
     or transfer.

(aa) Applicable  Rating Agency.  Rating triggers and other Rating  Agency-related  provisions herein apply
     only for so long as that particular Rating Agency is rating the certificates.

(bb) Timing of Payments by Party B upon Early  Termination.  Notwithstanding  anything to the  contrary in
     Section  6(d)(ii),  to the extent that all or a portion (in either case,  the  "Unfunded  Amount") of
     any amount that is  calculated  as being due in respect of any Early  Termination  Date under Section
     6(e) from  Party B to Party A will be paid by Party B from  amounts  other than any  upfront  payment
     paid to Party B by an Eligible  Replacement that has entered a Replacement  Transaction with Party B,
     then such Unfunded  Amount shall be due on the next subsequent  Distribution  Date following the date
     on which the payment would have been payable as determined in accordance with Section  6(d)(ii),  and
     on any subsequent  Distribution  Dates until paid in full (or if such Early  Termination  Date is the
     final Distribution Date, on such final Distribution  Date);  provided,  however,  that if the date on
     which the payment  would have been payable as determined  in  accordance  with Section  6(d)(ii) is a
     Distribution Date, such payment will be payable on such Distribution Date.

(cc) Safe Harbors.  Each party to this Agreement acknowledges that:
