(2)   GPCH LIMITED (registered number 4128437), a private limited company

      expressions shall include such persons and all other persons for the time
      being acting as note trustee or note trustees under the Current Issuer
      Deed of Charge).


IT IS HEREBY AGREED AS FOLLOWS:

1.    INTERPRETATION

      The provisions of:

      (a)   the Master Definitions Schedule as amended and restated by (and
            appearing in Appendix 1 to) the Master Definitions Schedule Third
            Amendment and Restatement Deed made on [o] 2002 between, among
            others, the Seller, Funding and the Mortgages Trustee, and

      (b)   the Issuer Master Definitions Schedule signed for the purposes of
            identification by Sidley Austin Brown & Wood and Allen & Overy on

      (as the same have been and may be amended, varied or supplemented from
      time to time with the consent of the parties hereto) are expressly and
      specifically incorporated into and shall apply to this Agreement.

      The Issuer Master Definitions Schedule shall prevail to the extent that it
      conflicts with the Master Definitions Schedule.


2.    OPTION

2.1   In the event that (a) the Current Issuer Security is enforced and, after
      payment of all other claims ranking in priority to the Current Issuer
      Notes under the Current Issuer Deed of Charge, the remaining proceeds of
      such enforcement are insufficient to pay in full all principal and
      interest and other amounts whatsoever due in respect of the Current Issuer
      Notes and all other claims ranking PARI PASSU therewith, or (b) within 20
      days following the Final Maturity Date of the latest maturing Notes, the
      Note Trustee certifies that there is no further amount outstanding under
      the Current Issuer Intercompany Loan, then all interests in the Global
      Note Certificates will be automatically exchanged (such date of exchange
      being the "OPTION EXERCISE DATE") for equivalent interests in an
      equivalent amount of Notes in an equivalent Principal



      Amount Outstanding represented by Individual Note Certificates and such
      Global Note Certificates will be cancelled.

2.2   In connection with the issuance of the Current Issuer Notes, the Note
      Trustee hereby grants, and the Current Issuer hereby acknowledges, an
      option (the "OPTION"), under which the Note Trustee has no personal
      liability, exercisable by the Post-Enforcement Call Option Holder (or by
      any designated subsidiary of the Post-Enforcement Call Option Holder, to
      be designated by notice from the Post-Enforcement Call Option Holder to
      the Note Trustee at the discretion of the Post-Enforcement Call Option
      Holder (the "DESIGNATED SUBSIDIARY") permitting the Post-Enforcement Call
      Option Holder (or any Designated Subsidiary) to acquire at any time on or
      after the Option Exercise Date all (but not some only) of the Relevant
      Notes (as defined below) outstanding as at the Option Exercise Date,
      together with accrued interest thereon ("RELEVANT NOTES" being for the
      purposes of this Deed, all the Current Issuer Notes represented by
      Individual Note Certificates as at the Option Exercise Date).

2.3   The Option shall be exercised by the Post-Enforcement Call Option Holder
      (or any Designated Subsidiary) by notice from the Post-Enforcement Call
      Option Holder (or the Designated Subsidiary) to the Note Trustee and the
      Noteholders in accordance with Condition 14 of the Current Issuer Notes.


3.    REPRESENTATIONS AND WARRANTIES
