      [A/B/M/C] Fourth Issuer Notes is downgraded or placed under review for
      possible downgrade by S&P (an "INITIAL S&P RATING EVENT"), then Party A

                                       25



      (A)  put in place an appropriate mark-to-market collateral agreement
           (which may be based on the credit support documentation published by
           ISDA, or otherwise, and relates to collateral in the form of cash or
           securities or both) in support of its obligations under this
           Agreement on terms satisfactory to the Security Trustee (whose
           consent will be given if S&P confirms that the provision of such
           collateral would maintain the rating of the Series 3 Class [A/B/M/C]
           Fourth Issuer Notes by S&P at, or restore the rating of the Series 3
           Class [A/B/M/C] Fourth Issuer Notes by S&P to, the level it would
           have been at immediately prior to such Initial S&P Rating Event)
           provided that (x) Party A will be deemed to have satisfied the
           requirements of S&P if the amount of collateral agreed to be provided
           in the form of cash and/or securities (the "COLLATERAL AMOUNT") is
           determined on a basis which satisfies (but is no more onerous than)
           the criteria of S&P published on 17th December, 2003, which enables
           entities rated lower than a specified level to participate in
           structured finance transactions which, through collateralisation are
           rated at a higher level (the "S&P CRITERIA"), (y) the Collateral
           Amount will not be required to exceed such amount as would be
           required (in accordance with the S&P Criteria) to maintain or restore
           the rating of the Series 3 Class [A/B/M/C] Fourth Issuer Notes at or
           to the level they would have been at immediately prior to such
           Initial S&P Rating Event [and (z) the enforceability of such
           collateral arrangement must be supported by legal opinions with
           respect to each relevant jurisdiction provided in a form reasonably
           acceptable to S&P within 30 days of the occurrence of such Initial
           S&P Rating Event];

      (B)  transfer all of its rights and obligations with respect to this
           Agreement to a replacement third party satisfactory to the Security
           Trustee (whose consent will be given if S&P confirms that such
           transfer would maintain the rating of the Series 3 Class [A/B/M/C]
           Fourth Issuer Notes by S&P at, or restore the rating of the Series 3
           Class [A/B/M/C] Fourth Issuer Notes by S&P to, the level it would
           have been at immediately prior to such Initial S&P Rating Event);

      (C)  obtain a guarantee of its rights and obligations with respect to this
           Agreement from a third party satisfactory to the Security Trustee
           (whose consent will be given if S&P confirms that such guarantee
           would maintain the rating of the Series 3 Class [A/B/M/C] Fourth
           Issuer Notes at, or restore the rating of the Series 3 Class
           [A/B/M/C] Fourth Issuer Notes to, the level it would have been at
           immediately prior to such Initial S&P Rating Event); or

      (D)  take such other action as Party A may agree with S&P as will result
           in the rating of the Series 3 Class [A/B/M/C] Fourth Issuer Notes
           following the taking of such action being maintained at, or restored
           to, the level it would have been at immediately prior to such Initial
           S&P Rating Event.

      If any of paragraphs (i)(B), (i)(C) or (i)(D) above are satisfied at any
      time, all collateral (or the equivalent thereof, as appropriate)
      transferred by Party A pursuant to paragraph (i)(A) above will be
      transferred to Party A and Party A will not be required to transfer any
      additional collateral.

(ii)  In the event that the long-term, unsecured and unsubordinated debt
      obligations of the Credit Support Provider of Party A (or its successor)
      cease to be rated at least as high as ["BBB-"] by S&P and, as a result of
      such downgrade, the then current rating of the Series 3 Class [A/B/M/C]
      Fourth Issuer Notes may in the reasonable opinion of S&P be downgraded or
      placed under review for possible downgrade (such event, a

                                       26



      "SUBSEQUENT S&P RATING EVENT"), then Party A will, within 30 days of the
      occurrence of such Subsequent S&P Rating Event, at its own cost either:

      (A)  transfer all of its rights and obligations with respect to this
           Agreement to a replacement third party satisfactory to the Security
           Trustee (whose consent will be given if S&P confirms that such
           transfer would maintain the rating of the Series 3 Class [A/B/M/C]
           Fourth Issuer Notes by S&P at, or restore the rating of the Series 3
           Class [A/B/M/C] Fourth Issuer Notes by S&P to, the level it would
           have been at immediately prior to such Subsequent S&P Rating Event);

      (B)  take such other action as Party A may agree with S&P as will result
           in the rating of the Series 3 Class [A/B/M/C] Fourth Issuer Notes
           following the taking of such action being maintained at, or restored
           to, the level it would have been at immediately prior to such
           Subsequent S&P Rating Event[; or

      (C)  obtain a guarantee of its rights and obligations with respect to this
           Agreement from a third party satisfactory to the Security Trustee
           (whose consent will be given if S&P confirms that such guarantee
           would maintain the rating of the Series 3 Class [A/B/M/C] Fourth
           Issuer Notes at, or restore the rating of the Series 3 Class
           [A/B/M/C] Fourth Issuer Notes to, the level it would have been at
           immediately prior to such Subsequent S&P Rating Event)],

      and, if, at the time a Subsequent S&P Rating Event occurs, Party A has
      provided collateral pursuant to a mark-to-market collateral arrangement
      put in place pursuant to paragraph (i)(A) above following an Initial S&P
      Rating Event, it will continue to post collateral notwithstanding the
      occurrence of a Subsequent S&P Rating Event until such time as any of
      paragraphs (ii)(A), (ii)(B) [or (ii)(C)] above have been satisfied.

      If any of paragraphs (ii)(A), (ii)(B) or (ii)(C) above are satisfied at
      any time, all collateral (or the equivalent thereof, as appropriate)
      transferred by Party A pursuant to paragraph (i)(A) above will be
      transferred to Party A and Party A will not be required to transfer any
      additional collateral.

(iii) In the event that the long-term, unsecured and unsubordinated debt
      obligations of the Credit Support Provider of Party A (or its successor)
      cease to be rated at least as high as the lower of (A) "A1" (or its
      equivalent) by Moody's and (B) the highest rating of the Series 3 Class
      [A/B/M/C] Fourth Issuer Notes then issued by Moody's immediately prior to
      such cessation (such cessation being an "INITIAL MOODY'S RATING EVENT"),
      then Party A will, within 30 days of the occurrence of such Initial
      Moody's Rating Event, at its own cost either:

      (1)  transfer all of its rights and obligations with respect to this
           Agreement to either (x) a replacement third party with the Required
           Ratings (as defined below) domiciled in the same legal jurisdiction
           as Party A or Party B, or (y) a replacement third party as agreed
           with Moody's;

      (2)  procure another person to become co-obligor or guarantor in respect
           of the obligations of Party A under this Agreement, which co-obligor
           or guarantor may be either (x) a person with the Required Ratings (as
           defined below) domiciled in the same legal jurisdiction as Party A or
           Party B, or (y) such other person as agreed with Moody's;

      (3)  take such other action as agreed with Moody's; or

                                       27



      (4)  put in place a mark-to-market collateral agreement in a form and
           substance acceptable to Moody's (which may be based on the credit
           support documentation published by ISDA, or otherwise, and relates to
           collateral in the form of cash or securities or both) in support of
           its obligations under this Agreement which complies with the Moody's
           Criteria (as defined below) or such other requirements as may be
           agreed with Moody's.

      If any of paragraphs (iii)(1), (iii)(2) or (iii)(3) above are satisfied at
      any time, all collateral (or the equivalent thereof, as appropriate)
      transferred by Party A pursuant to paragraph (iii)(4) above will be
      transferred to Party A and Party A will not be required to transfer any
      additional collateral.

(iv)  In the event that the long-term, unsecured and unsubordinated debt
      obligations of the Credit Support Provider of Party A (or its successor)
      cease to be rated as high as "A3" (or its equivalent) by Moody's (such
      cessation being a "SUBSEQUENT MOODY'S RATING EVENT"), then Party A will:

      (1)  on a best efforts basis within 30 days of the occurrence of such
           Subsequent Moody's Rating Event, at its own cost, attempt either to:

           (aa)  transfer all of its rights and obligations with respect to this
                 Agreement to either (x) a replacement third party with the
                 Required Ratings (as defined below) domiciled in the same legal
                 jurisdiction as Party A or Party B, or (y) a replacement third
                 party as agreed with Moody's;

           (bb)  procure another person to become co-obligor or guarantor in
                 respect of the obligations of Party A under this Agreement,
                 which co-obligor or guarantor may be either (x) a person with
                 the Required Ratings (as defined below) domiciled in the same
                 legal jurisdiction as Party A or Party B, or (y) such other
                 person as agreed with Moody's; or

           (cc)  take such other action agreed with Moody's; and

      (2)  within the later of 10 days of the occurrence of such Subsequent
           Moody's Rating Event and 30 days of the occurrence of an Initial
           Moody's Rating Event, put in place, at its own cost, pending
           compliance with paragraph (iv)(1)(aa), (iv)(1)(bb) or (iv)(1)(cc)
           above, a mark-to-market collateral agreement in a form and substance
           acceptable to Moody's (which may be based on the credit support
           documentation published by ISDA, or otherwise, and relates to
           collateral in the form of cash or securities or both) in support of
           its obligations under this Agreement which complies with the Moody's
           Criteria (as defined below) or such other requirements as may be
           agreed with Moody's, provided that, if, at the time a Subsequent
           Moody's Rating Event occurs, Party A has provided collateral pursuant
           to a mark-to-market collateral arrangement put in place pursuant to
           paragraph (iii)(4) above following an Initial Moody's Rating Event,
           it will continue to post collateral notwithstanding the occurrence of
           a Subsequent Moody's Rating Event.

      If any of paragraphs (iv)(1)(aa), (bb) or (cc) above are satisfied at any
      time, all collateral (or the equivalent thereof, as appropriate)
      transferred by Party A pursuant to paragraph (iv)(2) above will be
      transferred to Party A and Party A will not be required to transfer any
      additional collateral.

                                       28



For the purposes of paragraphs (iii) and (iv) of this Part 5(f), "REQUIRED
RATINGS" means, in respect of the relevant entity, its long-term, unsecured and
unsubordinated debt obligations are rated at least as high as "A2", or such
other rating as may be agreed with Moody's from time to time.

"MOODY'S CRITERIA" means that the Collateral Amount will equal the sum of (a)
the product of A multiplied by the mark-to-market value of the outstanding
Transactions as determined by Party A in good faith on each Local Business Day
and (b) the product of B multiplied by the current aggregate notional amounts of
the outstanding Transactions, where:

(w)   "A" means 102% and "B" means 0% if the long-term, unsecured and
      unsubordinated debt obligations of Party A's Credit Support Provider (or
      its successor), are downgraded below "A1" by Moody's;

(x)   "A" means 102% and "B" means 2.0% if the long-term, unsecured and
      unsubordinated debt obligations of Party A's Credit Support Provider (or
      its successor) are downgraded below "A2" by Moody's;

(y)   "A" will be equal to or greater than 102% (as determined by Moody's) and
      "B" will be equal to or greater than 3% (as determined by Moody's) if the
      long-term, unsecured and unsubordinated debt obligations of Party A's
      Credit Support Provider (or its successor), are downgraded below "Baa2" by
      Moody's; and

(z)   "A" means 0% and "B" means 0% in all other cases.

      In relation to paragraphs (iii)(4) and (iv)(2) above, Party A will, upon
      receipt of reasonable notice from Moody's demonstrate to Moody's the
      calculation by Party A of the mark-to-market value of the outstanding
      Transactions. In relation to paragraph (iv)(2) above, Party A will, at its
      own cost, on receipt of reasonable notice from Moody's and within 30 days
      of receipt of such notice arrange a third party valuation of the
      mark-to-market value of the outstanding Transactions.

      A failure by Party A to arrange such a valuation will not be or give rise
      to an Event of Default under Section 5(a)(ii) of this Agreement but will
      constitute an Additional Termination Event with Party A as the sole
      Affected Party and all Transactions as Affected Transactions.

(v)   In the event that the long-term, unsecured and unsubordinated debt
      obligations of the Credit Support Provider of Party A (or its successor)
      cease to be rated at least as high as "A+" (or its equivalent) by Fitch
      Ratings Ltd ("FITCH") and, as a result of such cessation, the then current
      rating of the Series 3 Class [A/B/M/C] Fourth Issuer Notes is downgraded
      or placed under review for possible downgrade by Fitch (an "INITIAL FITCH
      RATING EVENT") then Party A will, on a best efforts basis within 30 days
      of the occurrence of such Initial Fitch Rating Event, at its own cost,
      either:

      (A)  put in place an appropriate mark-to-market collateral agreement in a
           form and substance acceptable to Fitch (which may be based on the
           credit support documentation published by ISDA, or otherwise, and
           relates to collateral in the form of cash or securities or both to be
           posted on a weekly basis) in support of its obligations under this
           Agreement provided that (x) Party A will be deemed to have satisfied
           the requirements of Fitch if the Collateral Amount is determined on a
           basis which is no more onerous than the Fitch Criteria (as

                                       29



           defined below), and (y) the Collateral Amount will not be required to
           exceed such amount as would be required (in accordance with the Fitch
           Criteria) to maintain or restore the rating of the Series 3 Class
           [A/B/M/C] Fourth Issuer Notes at or to the level it would have been
           at immediately prior to such Initial Fitch Rating Event;

      (B)  transfer all of its rights and obligations with respect to this
           Agreement to a replacement third party satisfactory to the Security
           Trustee (whose consent will be given if Fitch confirms that such
           transfer would maintain the rating of the Series 3 Class [A/B/M/C]
           Fourth Issuer Notes by Fitch at, or restore the rating of the Series
           3 Class [A/B/M/C] Fourth Issuer Notes by Fitch to, the level it would
           have been at immediately prior to such Initial Fitch Rating Event);

      (C)  obtain a guarantee of its rights and obligations with respect to this
           Agreement from a third party satisfactory to the Security Trustee
           (whose consent will be given if Fitch confirms that such guarantee
           would maintain the rating of the Series 3 Class [A/B/M/C] Fourth
           Issuer Notes at, or restore the rating of the Series 3 Class
           [A/B/M/C] Fourth Issuer Notes to, the level it would have been at
           immediately prior to such Initial Fitch Rating Event); or

      (D)  take such other action as Party A may agree with Fitch as will result
           in the rating of the Series 3 Class [A/B/M/C] Fourth Issuer Notes
           following the taking of such action being maintained at, or restored
           to, the level it would have been at immediately prior to such Initial
           Fitch Rating Event.

      If any of paragraphs (v)(B), (v)(C) or (v)(D) above are satisfied at any
      time, all collateral (or the equivalent thereof, as appropriate)
      transferred by Party A pursuant to paragraph (v)(A) above will be
      transferred to Party A and Party A will not be required to transfer any
      additional collateral.

(vi)  In the event that the long-term, unsecured and unsubordinated debt
      obligations of the Credit Support Provider of Party A (or its successor)
      cease to be rated at least as high as "BBB+" (or its equivalent) by Fitch
      and, as a result of such cessation, the then current rating of the Series
      3 Class [A/B/M/C] Fourth Issuer Notes is downgraded or placed under review
      for possible downgrade by Fitch (a "SUBSEQUENT FITCH RATING EVENT") then
      Party A will:

      (A)  on a best efforts basis within 30 days of the occurrence of such
           Subsequent Fitch Rating Event, at its own cost, attempt either to:

           (1)  transfer all of its rights and obligations with respect to this
                Agreement to a replacement third party satisfactory to the
                Security Trustee (whose consent will be given if Fitch confirms
                that such transfer would maintain the rating of the Series 3
                Class [A/B/M/C] Fourth Issuer Notes by Fitch at, or restore the
                rating of the Series 3 Class [A/B/M/C] Fourth Issuer Notes by
                Fitch to, the level it would have been at immediately prior to
                such Subsequent Fitch Rating Event);

           (2)  obtain a guarantee of its rights and obligations with respect to
                this Agreement from a third party satisfactory to the Security
                Trustee (whose consent will be given if Fitch confirms that such
                guarantee would maintain the rating of the Series 3 Class
                [A/B/M/C] Fourth Issuer Notes at, or restore the rating of the
                Series 3 Class [A/B/M/C]

                                       30



                Fourth Issuer Notes to, the level it would have been at
                immediately prior to such Subsequent Fitch Rating Event); or

           (3)  take such other action as Party A may agree with Fitch as will
                result in the rating of the Series 3 Class [A/B/M/C] Fourth
                Issuer Notes following the taking of such action being
                maintained at, or restored to, the level it would have been at
                immediately prior to such Subsequent Fitch Rating Event; and

      (B)  within the later of 10 days of the occurrence of such Subsequent
           Fitch Rating Event and 30 days of the occurrence of an Initial Fitch
           Rating Event, put in place, at its own cost, pending compliance with
           paragraph (vi)(A)(1), (vi)(A)(2) or (vi)(A)(3) above, an appropriate
           mark-to-market collateral agreement in a form and substance
           acceptable to Fitch (which may be based on the credit support
           documentation published by ISDA, or otherwise, and relates to
           collateral in the form of cash or securities or both to be posted on
           a weekly basis) in support of its obligations under this Agreement
           provided that (x) Party A will be deemed to have satisfied the
           requirements of Fitch if the Collateral Amount is determined on a
           basis which is no more onerous than the Fitch Criteria (as defined
           below), and (y) the Collateral Amount will not be required to exceed
           such amount as would be required (in accordance with the Fitch
           Criteria) to maintain or restore the rating of the Series 3 Class
           [A/B/M/C] Fourth Issuer Notes or to the level it would have been at
           immediately prior to such Subsequent Fitch Rating Event, and provided
           that, if, at the time a Subsequent Fitch Rating Event occurs, Party A
           has provided collateral pursuant to a mark-to-market collateral
           arrangement put in place pursuant to paragraph (v)(A) above following
           an Initial Fitch Rating Event, it will continue to post collateral
           notwithstanding the occurrence of a Subsequent Fitch Rating Event.

      If any of paragraphs (vi)(A)(1), (2) or (3) above are satisfied at any
      time, all collateral (or the equivalent thereof, as appropriate)
      transferred by Party A pursuant to paragraph (vi)(B) above will be
      transferred to Party A and Party A will not be required to transfer any
      additional collateral.

      "FITCH CRITERIA" means that the Collateral Amount will equal the sum of
      (a) the product of A multiplied by the mark-to-market value of the
      outstanding Transactions as determined by Party A in good faith on a
      weekly basis and (b) the product of B multiplied by the current aggregate
      notional amounts of the outstanding Transactions, where "A" means 100% and
      "B" means 2.5%.

(vii) (A)  If Party A does not take any of the measures described in paragraph
           (i) above, such failure will not be or give rise to an Event of
           Default but will constitute an Additional Termination Event with
           respect to Party A which will be deemed to have occurred on the
           thirtieth day following the S&P Rating Event with Party A as the sole
           Affected Party and all Transactions as Affected Transactions.

      [(B) If, at the time a Subsequent S&P Rating Event occurs, Party A has
           provided collateral and fails to continue to post collateral pending
           compliance with any of paragraphs (ii)(A), (ii)(B) [or (ii)(C)]
           above, such failure will not be or give rise to an Event of Default
           but will constitute an Additional Termination Event with respect to
           Party A and will be deemed to have occurred on the [tenth] day
           following such Subsequent S&P Rating Event with Party A as the sole

                                       31



           Affected Party and all Transactions as Affected Transactions.
           Further, it will constitute an Additional Termination Event with
           respect to Party A if, even if it is posting collateral as required
           by paragraph (ii) above and notwithstanding Section 5(a)(ii), Party A
           does not take any of the measures described in paragraphs (ii)(A),
           (ii)(B) [or (ii)(C)] above. Such Additional Termination Event will be
           deemed to have occurred on the thirtieth day following the Subsequent
           S&P Rating Event with Party A as the sole Affected Party and all
           Transactions as Affected Transactions.]

      (C)  If Party A does not take any of the measures described in paragraph
           (iii)(1), (2), (3) or (4) above, such failure will not be or give
           rise to an Event of Default but will constitute an Additional
           Termination Event with respect to Party A and will be deemed to have
           occurred on the thirtieth day following the occurrence of such
           Initial Moody's Rating Event with Party A as the sole Affected Party
           and all Transactions as Affected Transactions.

      (D)  If Party A does not take the measures described in paragraph (iv)(2)
           above, such failure will give rise to an Event of Default with
           respect to Party A and will be deemed to have occurred on the later
           of the tenth day following such Subsequent Moody's Rating Event and
           the thirtieth day following an Initial Moody's Rating Event with
           Party A as the Defaulting Party. Further, it will constitute an
           Additional Termination Event with respect to Party A if, even after
           satisfying the requirements of paragraph (iv)(2) above and
           notwithstanding Section 5(a)(ii), Party A has failed, within 30 days
           following such Subsequent Moody's Rating Event, to either transfer as
           described in paragraph (iv)(1)(aa), find a co-obligor as described in
           paragraph (iv)(1)(bb) or take such other action as described in
           paragraph (iv)(1)(cc). Such Additional Termination Event will be
           deemed to have occurred on the thirtieth day following such
           Subsequent Moody's Rating Event with Party A as the sole Affected
           Party and all Transactions as Affected Transactions.

      (E)  If Party A does not take the measures described in paragraph (v)
           above, such failure will not be or give rise to an Event of Default
           but will constitute an Additional Termination Event with respect to
           Party A which will be deemed to have occurred on the thirtieth day
           following the Initial Fitch Rating Event with Party A as the sole
           Affected Party and all Transactions as Affected Transactions.

      (F)  If Party A does not take the measures described in paragraph (vi)(B)
           above, such failure will give rise to an Event of Default with
           respect to Party A and will be deemed to have occurred on the later
           of the tenth day following such Subsequent Fitch Rating Event and the
           thirtieth day following an Initial Fitch Rating Event with Party A as
           the Defaulting Party. Further, it will constitute an Additional
           Termination Event with respect to Party A if, even after satisfying
           the requirements of paragraph (vi)(B) above and notwithstanding
           Section 5(a)(ii), Party A has failed, within 30 days following such
           Subsequent Fitch Rating Event, to either transfer as described in
           paragraph (vi)(A)(1), find a co-obligor as described in paragraph
           (vi)(A)(2) or take such other action as described in paragraph
           (vi)(A)(3). Such Additional Termination Event will be deemed to have
           occurred on the thirtieth day following such Subsequent Fitch Rating
           Event with Party A as the sole Affected Party and all Transactions as
           Affected Transactions.

                                       32



      (G)  In the event that Party B were to designate an Early Termination Date
           and there would be a payment due to Party A, Party B may only
           designate such an Early Termination Date in respect of an Additional
           Termination Event under this Part 5(f) if Party B has found a
           replacement counterparty willing to enter into a new transaction on
           terms that reflect as closely as reasonably possible, as determined
           by Party B in its sole and absolute discretion, the economic, legal
           and credit terms of the Terminated Transactions with Party A, and
           Party B has acquired the Security Trustee's prior written consent.

Each of Party B and the Security Trustee will use their reasonable endeavours to
co-operate with Party A in putting in place such credit support documentation,
including agreeing to such arrangements in such documentation as may satisfy
S&P, Moody's and/or Fitch, as applicable, with respect to the operation and
management of the collateral and entering into such documents as may reasonably
be requested by Party A in connection with the provision of such collateral.

(g)   TRANSFER POLICY

Section 7 of this Agreement will not apply to Party A, who will be required to
comply with, and will be bound by, the following:

Without prejudice to Section 6(b)(ii) as amended in this Schedule, Party A may
transfer all (but not part only) of its interests and obligations in and under
this Agreement to any of its Affiliates or, with the prior written consent of
Party B, such consent not to be unreasonably withheld, to any other entity (each
such Affiliate or entity a "TRANSFEREE") upon providing five Business Days'
prior written notice to the Note Trustee, provided that:

(i)   the Transferee's long-term, unsecured and unsubordinated debt obligations
      are then rated not less than "AA-" by S&P, "A1" by Moody's and "A+" by
      Fitch (or its equivalent by any substitute rating agency) or such
      Transferee's obligations under this Agreement are guaranteed by an entity
      whose long-term, unsecured and unsubordinated debt obligations are then
      rated not less than "AA-" by S&P, "A1" by Moody's and "A+" by Fitch (or
      its equivalent by any substitute rating agency);

(ii)  the Ratings Agencies have confirmed that the transfer will not result in
      the then current rating of the Series 3 Class [A/B/M/C] Fourth Issuer
      Notes being downgraded;

(iii) the Transferee will not, as a result of such transfer, be required on the
      next succeeding Scheduled Payment Date to withhold or deduct on account of
      any Tax (except in respect of default interest) amounts in excess of that
      which Party A would, on the next succeeding Scheduled Payment Date have
      been required to so withhold or deduct unless the Transferee would be
      required to make additional payments pursuant to Section 2(d)(i)(4)
      corresponding to such excess;

(iv)  a Termination Event or Event of Default does not occur as a result of such
      transfer;

(v)   no additional amount will be payable by Party B to Party A or the
      Transferee on the next succeeding Scheduled Payment Date as a result of
      such transfer; and

(vi)  the Transferee confirms in writing that it will accept all of the
      interests and obligations in and under this Agreement which are to be
      transferred to it in accordance with the terms of this provision.

                                       33



With respect to paragraph (iii) above, each party agrees to make such Payee Tax
Representations and Payer Tax Representations as may reasonably be requested by
the other party in order to reasonably satisfy such other party that such
withholding or deduction will not occur.

Following the transfer, all references to Party A (or its Credit Support
Provider, as applicable) will be deemed to be references to the Transferee.

Save as otherwise provided for in this Agreement and notwithstanding Section 7,
Party A will not be permitted to transfer (by way of security or otherwise) this
Agreement nor any interest or obligation in or under this Agreement without the
prior written consent of the Security Trustee.

(h)   ADDITIONAL REPRESENTATION

Section 3 is amended by the addition at the end thereof of the following
additional representations (provided that the representation in Section 3(h)
will be made by Party A only):

      "(g) NO AGENCY. It is entering into this Agreement, including each
      Transaction, as principal and not as agent of any person or entity.

      (h)  PARI PASSU. Its obligations under this Agreement rank pari passu with
           all of its other unsecured, unsubordinated obligations except those
           obligations preferred by operation of law."

(i)   RECORDING OF CONVERSATIONS

Each party to this Agreement (i) consents to the recording of the telephone
conversations of trading, marketing and operations personnel of the parties in
connection with this Agreement or any potential Transaction, (ii) agrees to
obtain any necessary consent of, and give notice of such recording to, such
personnel of it and (iii) agrees that in any Proceedings it will not object to
the introduction of such recordings in evidence on the ground that consent was
not properly given.

(j)   RELATIONSHIP BETWEEN THE PARTIES

The Agreement is amended by the insertion after Section 14 of an additional
Section 15, reading in its entirety as follows:

"15.  RELATIONSHIP BETWEEN THE PARTIES

Each party will be deemed to represent to the other party on the date on which
it enters into a Transaction that (absent a written agreement between the
parties that expressly imposes affirmative obligations to the contrary for that
Transaction):

(a)   NON RELIANCE. It is acting for its own account, and it has made its own
      independent decisions to enter into that Transaction and as to whether
      that Transaction is appropriate or proper for it based upon advice from
      such advisers 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 will not be considered investment advice or a recommendation
      to enter into that Transaction. No communication (written or oral)
      received from the other

                                       34



      party will be deemed to be an assurance or guarantee as to the expected
      results of that Transaction.

(b)   ASSESSMENT AND UNDERSTANDING. It is capable of assessing the merits of and
      understanding (on its own behalf or through independent professional
      advice), and understands and accepts, the terms, conditions and risks of
      that Transaction. It is also capable of assuming, and assumes, the
      financial and other risks of that Transaction.

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

(k)   TAX

The Agreement is amended by deleting Section 2(d) in its entirety and replacing
it with the following:

"(d)  Deduction or Withholding for Tax

(i)   Requirement to Withhold

      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 (including, for the avoidance of doubt, if such
      deduction or withholding is required in order for the payer to obtain
      relief from Tax) by any applicable law, as modified by the practice of any
      relevant governmental revenue authority, then in effect. If a party ("X")
      is so required to deduct or withhold, then that party (the "DEDUCTING
      PARTY"):

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

      (2)  will 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 Gross Up Amount (as defined below) paid
           by the Deducting Party 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)  will 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 X is Party A, X will promptly pay in addition to the payment to
           which Party B is otherwise entitled under this Agreement, such
           additional amount (the "GROSS UP AMOUNT") as is necessary to ensure
           that the net amount actually received by Party B will equal the full
           amount which Party B would have received had no such deduction or
           withholding been required.

(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 for or on account of any Tax; and

                                       35



      (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 that Y has satisfied or then satisfies the
      liability resulting from such Tax, (A) where X is Party B, Party A will
      promptly pay to Party B the amount of such liability (the "LIABILITY
      AMOUNT") (including any related liability for interest and together with
      an amount equal to the Tax payable by Party B on receipt of such amount
      but including any related liability for penalties only if Party A has
      failed to comply with or perform any agreement contained in Section
      4(a)(i), 4(a)(iii) or 4(d)) and Party B will promptly pay to the relevant
      government revenue authority the amount of such liability (including any
      related liability for interest and penalties) and (B) where X is Party A
      and Party A would have been required to pay a Gross Up Amount to Party B,
      Party A will promptly pay to the relevant government revenue authority the
      amount of such liability (including any related liability for interest and
      penalties).

(iii) Tax Credit etc.

      Where Party A pays an amount in accordance with Section 2(d)(i)(4) above,
      Party B undertakes as follows:

      (1)  to the extent that Party B obtains any Tax credit, allowance, set-off
           or repayment from the tax authorities of any jurisdiction relating to
           any deduction or withholding giving rise to such payment (a "TAX
           CREDIT"), it will pay to Party A as soon as practical after receipt
           of the same so much of the cash benefit (as calculated below)
           relating thereto which it has received as will leave Party B in
           substantially the same (but in any event no worse) position as Party
           B would have been in if no such deduction or withholding had been
           required;

      (2)  the "cash benefit" will, in the case of a Tax credit, allowance or
           set-off, be the additional amount of Tax which would have been
           payable by Party B in the jurisdiction referred to in clause (1)
           above but for the obtaining by it of the said Tax credit, allowance
           or set-off and, in the case of a repayment, will be the amount of the
           repayment together, in either case, with any related interest or
           similar payment obtained by Party B;

      (3)  it will use all reasonable endeavours to obtain any Tax Credit as
           soon as is reasonably practicable provided that it will be the sole
           judge of the amount of such Tax Credit and of the date on which the
           same is received and will not be obliged to disclose to Party A any
           information relating to its tax affairs or tax computations save that
           Party B will, upon request by Party A, supply Party A with a
           reasonably detailed explanation of its calculation of the amount of
           any such Tax Credit and of the date on which the same is received;
           and

      (4)  it will ensure that any Tax Credit obtained is paid directly to Party
           A, and not applied in whole or part to pay any other Issuer Secured
           Creditor or any other party, both prior to and subsequent to any
           enforcement of the security constituted by the Fourth Issuer Deed of
           Charge."

                                       36



(l)   SECURITY, ENFORCEMENT AND LIMITED RECOURSE

(i)   Party A agrees with Party B and the Security Trustee to be bound by the
      terms of the Fourth Issuer Deed of Charge and, in particular, confirms
      that: (A) no sum will be payable by or on behalf of Party B to it except
      in accordance with the provisions of the Fourth Issuer Deed of Charge; and
      (B) it will not take any steps for the winding up, dissolution or
      reorganisation or for the appointment of a receiver, administrator,
      administrative receiver, trustee, liquidator, sequestrator or similar
      officer of Party B or of any or all of its revenues and assets nor
      participate in any ex parte proceedings nor seek to enforce any judgment
      against Party B, subject to the provisions of the Fourth Issuer Deed of
      Charge.

(ii)  In relation to all sums due and payable by Party B to Party A, Party A
      agrees that it will have recourse only to Fourth Issuer Available Funds,
      but always subject to the order of priority of payments set out in the
      Fourth Issuer Cash Management Agreement and the Fourth Issuer Deed of
      Charge.

(m)   CONDITION PRECEDENT

Section 2(a)(iii) will be amended by the deletion of the words "a Potential
Event of Default" in respect of obligations of Party A only.

(n)   REPRESENTATIONS

Section 3(b) will be amended by the deletion of the words "or Potential Event of
Default" in respect of the representation given by Party B only.

(o)   ADDITIONAL DEFINITIONS

Words and expressions defined in the Amended and Restated Master Definitions and
Construction Schedule (the "MASTER SCHEDULE") and the Fourth Issuer Master
Definitions and Construction Schedule (the "ISSUER SCHEDULE") (together the
"MASTER DEFINITIONS SCHEDULE") signed on or about {circle}, 2004 will, except so
far as the context otherwise requires, have the same meaning in this Agreement.
In the event of any inconsistency between the definitions in this Agreement and
in the Master Definitions Schedule the definitions in this Agreement will
prevail. In the event of any inconsistency between the Master Schedule and the
Issuer Schedule, the Issuer Schedule will prevail. The rules of interpretation
set out in the Master Definitions Schedule will apply to this Agreement.

(p)   CHANGE OF ACCOUNT

Section 2(b) of this Agreement is hereby amended by the addition of the
following at the end thereof:

"; provided that such new account will be in the same legal and tax jurisdiction
as the original account and such new account, in the case of Party B, is held
with a financial institution with a short-term, unsecured, unsubordinated and
unguaranteed debt obligation rating of at least "Prime-1" (in the case of
Moody's), "A-1+" (in the case of S&P) and "F1+" (in the case of Fitch) (or, if
such financial institution is not rated by a Rating Agency, at such equivalent
rating that is acceptable to such Rating Agency)."

                                       37



(q)   MODIFICATIONS TO CLOSE-OUT PROVISIONS

Upon the occurrence of an Event of Default with respect to Party A or an
Additional Termination Event which entitles Party B to terminate any Affected
Transaction pursuant to Section 6(b) of the Agreement, Party B will be entitled
(but not obliged in the event that it does not designate an Early Termination
Date) to proceed in accordance with Section 6 of this Agreement, subject to the
following:

(i)   For the purposes of Section 6(d)(i), Party B's obligation with respect to
      the extent of information to be provided with its calculations is limited
      to information Party B has already received in writing and provided Party
      B is able to release this information without breaching the provisions of
      any law applicable to, or any contractual restriction binding upon, Party
      B.

(ii)  The following amendments will be deemed to be made to the definition of
      "Market Quotation":

      (A)  the word "firm" will be added before the word "quotations" in the
           second line; and

      (B)  the words ", provided that such documentation would either be the
           same as this Agreement and the existing confirmations hereto (and the
           long-term, unsecured and unsubordinated debt obligations of the
           Reference Market-maker are rated not less than "AA-" by S&P and "A1"
           by Moody's and the short-term, unsecured and unsubordinated debt
           obligations of the Reference Market-maker are rated not less than
           "Prime-1" by Moody's and "A+" by Fitch (or, if such Reference
           Market-maker is not rated by a Rating Agency, at such equivalent
           rating that is acceptable to such Rating Agency)) or the Rating
           Agencies have confirmed in writing that such proposed documentation
           will not adversely impact the ratings of the Notes" will be added
           after "agree" in the sixteenth line; and

      (C)  the last sentence will be deleted and replaced with the following:

           "If, on the last date set for delivery of quotations, exactly two
           quotations are provided, the Market Quotation will be either (a) the
           lower of the two quotations where there would be a sum payable by
           Party A to Party B, or (b) the higher of the two quotations where
           there would be a sum payable by Party B to Party A. If only one
           quotation is provided on such date, Party B may, in its discretion,
           accept such quotation as the Market Quotation and, if Party B does
           not accept such quotation (or if no quotation has been provided), it
           will be deemed that the Market Quotation in respect of the Terminated
           Transaction cannot be determined. If no quotation has been provided,
           it will be deemed that the Market Quotation in respect of the
           Terminated Transaction cannot be determined."

(iii) For the purpose of the definition of "Market Quotation", and without
      limitation of the general rights of Party B under the Agreement:

      (A)  Party B will undertake to use its reasonable efforts to obtain at
           least three firm quotations as soon as reasonably practicable after
           the Early Termination Date and in any event within the time period
           specified pursuant to Part 5(q)(iii)(C) below;

                                       38



      (B)  Party A will, for the purposes of Section 6(e), be permitted to
           obtain on behalf of Party B quotations from Reference Market-makers;

      (C)  If no quotations have been obtained within 6 Local Business Days
           after the occurrence of the Early Termination Date or such longer
           period as Party B may specify in writing to Party A, then it will be
           deemed that the Market Quotation in respect of the Terminated
           Transaction cannot be determined;

      (D)  Party B will be deemed to have discharged its obligations under Part
           5(q)(iii)(A) above if it promptly requests, in writing, Party A (such
           request to be made within two Local Business Days after the
           occurrence of the Early Termination Date) to obtain on behalf of
           Party B quotations from Reference Market-makers. Party A agrees to
           act in accordance with such request; and

      (E)  Party B will not be obliged to consult with Party A as to the day and
           time of obtaining any quotations.

(r)   TERMINATION RIGHTS OF CREDIT SUPPORT PROVIDER

The following will constitute an Additional Termination Event:

If, 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 the
Credit Support Provider of Party A (or its successor or assignee) or a party to
this Agreement) or (y) a Change in Tax Law, the Credit Support Provider of Party
A (or its successor or assignee) would, on the next succeeding Scheduled Payment
Date, provided that a payment under the Credit Support Document in respect of
Party A were then due, be required to pay to Party B an additional amount in
respect of an Indemnifiable Tax under Section 8(a) of such Credit Support
Document (other than in respect of default interest).

For the purposes of this Part 5(r):

(i)   the definition of "law" shall be amended by the insertion of the words
      "either generally or with respect to a party to the Credit Support
      Document in respect of Party A" after the phrase "any relevant
      governmental authority" and the addition of the words "Change in Tax Law"
      before the word "lawful" on the second line; and

(ii)  "Indemnifiable Tax" shall have the meaning given to it in Section 8(a)(iv)
      of the Credit Support Document in respect of Party A.

For the purposes of the foregoing Additional Termination Event, Party A will be
the sole Affected Party and all Transactions will be Affected Transactions,
provided that, for the purposes of Section 6(b)(iv) only, Party B will be deemed
to be the sole Affected Party. Notwithstanding the foregoing, if the Security
Trustee gives notice to Party A and its Credit Support Provider that it wishes
the relevant Transactions to remain in effect, such Additional Termination Event
will be deemed not to have occurred.

(s)   CONTRACTS (RIGHTS OF THIRD PARTIES) ACT 1999

Except as contemplated by the provisions of Part 5(r) above, a person who is not
a party to this

                                       39



Agreement will not have any right under the Contracts (Rights of Third Parties)
Act 1999 to enforce any of its terms but this will not affect any right or
remedy of a third party which exists or is available apart from that Act.
