              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

              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) and (ii) be required to post collateral

              counterparty as  set forth in (3)(a) above within 30 days of the Ratings Event, then Party A
              shall continue to seek a substitute  counterparty and, on or prior to the expiration of such
              period,   post   collateral   according   to  the  terms  of  the  Credit   Support   Annex.

              transfer its rights and obligations under this Agreement  pursuant to this Part 5(b)(3) as a
              result of a rating issued by S&P,  Party A shall,  at all times prior to such  transfer,  be

] shall be the sole Transaction under the Agreement.

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

         Except as stated under  Section  6(b)(ii),  provided  that to the extent Party A makes a transfer
         pursuant to Section  6(b)(ii) it will provide a prior  written  notice to the Rating  Agencies of
         such transfer,  neither Party A nor Party B is permitted to assign,  novate or transfer  (whether
         by way of  security  or  otherwise)  as a whole  or in part  any of its  rights,  obligations  or
         interests  under this  Agreement  or any  Transaction  without the prior  written  consent of the
         other  party;  provided,  however,  that (i) Party A may make such a transfer  of this  Agreement
         pursuant  to a  consolidation  or  amalgamation  with,  or merger  with or into,  or  transfer of
         substantially  all of its assets to, another  entity,  or an  incorporation,  reincorporation  or
         reconstitution,  and (ii) Party A may  transfer  this  Agreement to any Person that is an office,
         branch or affiliate of Party A (any such Person,  office,  branch or affiliate,  a Transferee) on
         at least five Business  Days' prior written  notice to Party B;  provided  that,  with respect to
         clause  (ii),  (A) as of the  date of such  transfer  the  Transferee  will  not be  required  to
         withhold  or deduct on  account  of a Tax from any  payments  under  this  Agreement  unless  the
         Transferee  will be  required  to  make  payments  of  additional  amounts  pursuant  to  Section
         2(d)(i)(4)  of this  Agreement  in  respect  of such  Tax;  (B) a  Termination  Event or Event of
         Default  does not occur under this  Agreement  as a result of such  transfer;  (C) such notice is
         accompanied by a written  instrument  pursuant to which the  Transferee  acquires and assumes the
         rights and  obligations of Party A so  transferred;  and (D) Party A will be responsible  for any
         costs  or  expenses  incurred  in  connection  with  such  transfer.  Party B will  execute  such
         documentation  as is  reasonably  deemed  necessary by Party A for the  effectuation  of any such
         transfer.   Notwithstanding   the   foregoing,   no  such  transfer  shall  be  made  unless  the
         transferring  party  obtains a written  acknowledgment  from each of the  Rating  Agencies  that,
         notwithstanding  such transfer,  the then-current ratings of the Offered Certificates will not be
         reduced or withdrawn,  provided,  however,  that this  provision  shall not apply to any transfer
         that is made pursuant to the provisions of Part 5(b) of this Agreement.

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

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

     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

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

     Certificates  (other than  information  provided by Party A for purposes of the  disclosure  document
     relating to the Offered  Certificates);  (vi) the ongoing  operations and  administration of Party B,
     including the furnishing of any information to Party B which is not specifically  required under this

     Party A shall not be entitled to take any further  steps  against Party B to recover any sums due but
     still unpaid hereunder or thereunder,  all claims in respect of which shall be extinguished.  Party A
     hereby  agrees that,  notwithstanding  any  provision of this  agreement to the  contrary,  Party B's
     obligations  to pay any amounts  owing under Section 6(e) of this  Agreement  where Party A is either

     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

(t)  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.

(u)  Escrow  Payments.  If (whether by reason of the time difference  between the cities in which payments
     are to be made or otherwise) it is not possible for  simultaneous  payments to be made on any date on
     which both parties are  required to make  payments  hereunder,  either party may at its option and in
     its sole  discretion  notify the other party that payments on that date are to be made in escrow.  In
     this case  deposit of the  payment  due  earlier on that date shall be made by 2:00 pm (local time at
     the place for the  earlier  payment)  on that date with an escrow  agent  selected  by the  notifying
     party,  accompanied by irrevocable  payment  instructions (i) to release the deposited payment to the
     intended  recipient  upon receipt by the escrow agent of the  required  deposit of the  corresponding
     payment from the other party on the same date  accompanied by  irrevocable  payment  instructions  to
     the same  effect or (ii) if the  required  deposit of the  corresponding  payment is not made on that
     same date,  to return the payment  deposited  to the party that paid it into  escrow.  The party that
     elects to have payments made in escrow shall pay all costs of the escrow arrangements.
