2.       AGREEMENTS BY THE CONDITIONAL PURCHASER AND THE ISSUER

2.1      TERM OF CONDITIONAL PURCHASE COMMITMENT

         (a)      The Conditional Purchaser makes this Conditional Purchase
                  Commitment (i) to the Remarketing Bank and (ii) if the
                  Remarketing Bank is terminated pursuant to Clause 4 of the
                  Remarketing Agreement and no replacement Remarketing Bank has
                  been appointed, to the Issuer Cash Manager.

         (b)      Save as otherwise provided in this Agreement, the Issuer Cash
                  Manager or the Remarketing Bank may deliver, not more than
                  sixty (60) days and not less than forty (40) days before the
                  end of each Conditional Purchase Commitment Period, to the
                  Conditional Purchaser an irrevocable request in writing to
                  extend the Conditional Purchase Commitment Period,
                  substantially in the form of Schedule 1 hereto (an "EXTENSION
                  REQUEST") to the date that is not more than 364 days following
                  the last day of the current Conditional Purchase Commitment
                  Period.

         (c)      If the Conditional Purchaser wishes to accept an Extension
                  Request then it shall deliver, by not less than 30 days before
                  the last day of the current Conditional Purchase Commitment
                  Period, to the Issuer Cash Manager and the Remarketing Bank an
                  irrevocable notice, substantially in the form of Schedule 2
                  hereto ("NOTICE OF EXTENSION") that the Conditional Purchaser
                  has consented to the Extension Request. Failure to deliver
                  such a Notice of Extension by the day referred to above shall
                  be deemed a refusal to grant an extension of the Conditional
                  Purchase Commitment Period.

         (d)      The Conditional Purchaser is not obliged to agree to extend
                  the Conditional Purchase Commitment Period and in no event
                  (unless otherwise agreed in writing by the parties to this
                  Agreement) will it be extended beyond the Transfer Date
                  occurring in August 2010. The Conditional Purchaser will not
                  extend the Conditional Purchase Commitment Period unless the
                  Standard & Poor's and Moody's have confirmed in writing that
                  the then current rating of the commercial paper issued by the
                  Conditional Purchaser will not be reduced or withdrawn as a
                  consequence of the extension of the Conditional Purchase
                  Commitment.

         (e)      The Remarketing Bank agrees to deliver an Extension Request to
                  the Conditional Purchaser prior to each Transfer Date through
                  and including the Transfer Date occurring in August 2010,
                  pursuant to Clause 2.1(b) above, unless instructed otherwise
                  by the Issuer Cash Manager.

2.2      REMARKETING OF CLASS A NOTES AND CONDITIONAL PURCHASE BY THE
         CONDITIONAL PURCHASER

         (a)      The Conditional Purchaser agrees to purchase some or all of
                  the Class A Notes at any time during the Conditional Purchase
                  Commitment Period at the applicable Transfer Price (not to
                  exceed $1,000,000,000 outstanding at any time) payable on each
                  Transfer Date, on the terms of this Agreement and the
                  Remarketing Agreement, as specified in the Conditional
                  Purchase Activation Notice described in this Clause (the
                  "CONDITIONAL PURCHASE COMMITMENT").

                  For the avoidance of doubt, the Conditional Purchase
                  Commitment shall not, at any time, exceed $1,000,000,000.

         (b)      The Remarketing Bank will give notice to the Conditional
                  Purchaser in writing, substantially in the form of Schedule 3
                  hereto (a "CONDITIONAL PURCHASE ACTIVATION NOTICE"), (i) in
                  accordance with Clause 3.7 of the Remarketing Agreement and
                  (ii) immediately upon the occurrence of a Remarketing
                  Termination Event, which notice shall be irrevocable. The
                  Conditional Purchaser agrees to purchase all of the
                  Unremarketed Notes in accordance with the provisions of this
                  Agreement and as specified in the Conditional Purchase
                  Activation Notice.

                           that a Remarketing Termination Event (other than
                           pursuant to Clause 5.1(a) of the Remarketing
                           Agreement) has occurred on or before the relevant
                           Transfer Date;

                  (ii)     the Unremarketed Notes to be purchased by the
                           Conditional Purchaser on the Transfer Date specified
                           therein;

                  (iii)    the Transfer Price payable by the Conditional
                           Purchaser to the Securities Account on the Transfer
                           Date specified therein; and

                  (iv)     that the Remarketing Bank has not received notice
                           from (i) the Note Trustee that any of the events
                           specified in Clause 2.2(d)(i) and (ii) below has
                           occurred and is continuing and the Remarketing Agent
                           is otherwise not aware that any of the events in
                           Clause 2.2(d) below has occurred and is continuing.

         (d)      The obligation of the Conditional Purchaser to purchase the
                  Unremarketed Notes on any Transfer Date shall be subject to
                  the conditions that:

                  (i)      no Note Event of Default has occurred and is
                           continuing;

                  (ii)     no Conditional Purchase Loss Event has occurred and
                           is continuing;

                  (v)      the Conditional Purchaser shall not have received

                           pay all amounts of interest on the Class A Notes
                           scheduled to be paid on such Transfer Date,

         to this Agreement that the Conditional Purchaser has the requisite

                           added tax) which it may incur as a result or arising
                           out of or in relation to any inaccuracy or alleged
                           inaccuracy contained in, or any breach or alleged
                           breach of, any of the representations and warranties
                           in Clause 3.1 or any breach or alleged breach of any
                           of the undertakings in Clause 4.1; and

                                       8



                  (ii)     furnish to the Conditional Purchaser on the date
                           hereof a copy of the Prospectus certified by a duly
                           authorised officer of the Issuer and, without charge,
                           such additional number of copies of the Prospectus as
                           the Conditional Purchaser may reasonably request.

         (b)      The Note Trustee undertakes to the Conditional Purchase that
                  it will so long as any of the Class A Notes remains
                  outstanding, furnish to the Conditional Purchaser copies of
                  any notice given to Class A Noteholders under the Issuer Trust
                  Deed;

         (c)      The Issuer Cash Manager undertakes that it will:

                  (i)      notify the Remarketing Bank and the Conditional
                           Purchaser not less than ten (10) Business Days of
                           each Transfer Date if any of the events specified in
                           Clause 2.2(d) has occurred and is continuing; and

                  (ii)     on or prior to the tenth (10th) Business Day prior to
                           each Transfer Date provide notice to the Remarketing
                           Bank and the Conditional Purchaser as to whether or
                           not there will be insufficient Issuer Available
                           Revenue Receipts or Issuer Available Principal
                           Receipts to pay all amounts of interest on and
                           principal of the Class A Notes scheduled to be paid
                           on such Transfer Date.

         (d)      The Conditional Purchaser undertakes to the Remarketing Bank

4.2      If any claim,  demand or action is brought or asserted under Clause
         4.1(a)(i)  (each a "CLAIM"),  the following provisions shall apply:

         (a)      NOTIFICATION: the Conditional Purchaser (here the "INDEMNIFIED
                  PERSON") shall promptly notify Northern Rock (here the
                  "INDEMNIFYING PARTY") as soon as reasonably practicable after
                  becoming aware of a Claim (but failure to do so shall not
                  relieve the Indemnifying Party from liability);

         (b)      ASSUMPTION OF DEFENCE: the Indemnifying Party shall, subject
                  to Clause 4.4, be entitled to assume the defence of the
                  relevant Claim including the retention of legal advisers
                  approved by each Indemnified Person (which shall not be
                  unreasonably withheld or delayed), subject to the payment by
                  the Indemnifying Party of all legal and other expenses of such
                  defence; and

         (c)      SEPARATE REPRESENTATION: if the Indemnifying Party assumes the
                  defence of the relevant Claim, each Indemnified Person shall
                  be entitled to retain separate legal advisers and to
                  participate in such defence but the legal or other expenses
                  incurred in so doing shall, subject to Clause 4.4, be borne by
                  such Indemnified Person unless the Indemnifying Party has
                  specifically authorised such retention or participation.

4.3      Notwithstanding Clause 4.2, the Indemnified Person may retain separate
         legal advisers in each relevant jurisdiction and direct the defence of
         the relevant Claim. The Indemnifying Party shall reimburse the
         Indemnified Person for any legal or other expenses reasonably so
         incurred if:

                                       9



         (a)      INDEMNIFYING PARTY'S FAILURE: the Indemnifying Party (having
                  assumed such defence) fails properly to make such defence or
                  to retain for such purpose legal advisers approved by such
                  Indemnified Person;

         (b)      CONFLICT OF INTEREST: such Indemnified Person has reasonably
                  concluded that the use of any legal advisers chosen by the
                  Indemnifying Party to represent such Indemnified Person would
                  present such legal advisers with a conflict of interest; or

         (c)      DIFFERENT DEFENCES: the actual or potential defendants in, or
                  targets of, such Claim include both the Indemnifying Party and
                  such Indemnified Person and such Indemnified Person has
                  reasonably concluded that there are legal defences available
                  to it which are different from or additional to those
                  available to the Indemnifying Party.

4.4      The Indemnifying Party shall not, without the prior written consent of
         the Indemnified Person, settle or compromise, or consent to the entry
         of judgement with respect to, any pending or threatened Claim
         (irrespective of whether any Indemnified Person is an actual or
         potential defendant in, or target of, such Claim) unless such
         settlement, compromise or consent includes an unconditional release of
         each Indemnified Person from all liability arising out of the matters
         which are the subject of such claim. The Indemnifying Party shall not
         be liable to indemnify any Indemnified Person where the relevant Claim
         has been settled or compromised without its written consent (which
         shall not be unreasonably withheld).

4.5      The rights and remedies conferred upon the Conditional Purchaser under
         this Clause shall continue in full force and effect notwithstanding the
         completion of the arrangements set out herein for the purchase of, and
         payment for, the Class A Notes and regardless of any investigation made
         by the Conditional Purchaser.

5.       CLOSING OF CONDITIONAL PURCHASE

5.1      PAYMENT

         As soon as is practicable in the working day in New York on each
         Transfer Date, the Conditional Purchaser will pay or cause to be paid
         to the Custodial Account the Transfer Price in respect of the relevant
         Unremarketed Notes specified in the Conditional Purchase Activation
         Notice applicable to such Transfer Date. The Remarketing Bank will hold
         the Transfer Price in the manner contemplated by Clause 3.13 of the
         Remarketing Agreement pending completion of the transfer of the
         relevant Unremarketed Notes in accordance with Clause 5.2.

5.2      TRANSFER

         The Remarketing Bank will procure the transfer of interests in the
         Unremarketed Notes to the Securities Account and will hold those
         interests in accordance with Clause 3.13 of the Remarketing Agreement
         and deliver them to the Conditional Purchaser against payment of the
         relevant Transfer Price.

6.       FEES

                                       10



         In consideration of the agreement by the Conditional Purchaser to make
         the Conditional Purchase Commitment, the Issuer agrees to pay or
         procure the payment to the Conditional Purchaser of a commitment fee as
         agreed in a fee letter of even date herewith between the Issuer and the
         Conditional Purchaser.

7.       TERMINATION OF THIS AGREEMENT

7.1      TERMINATION OF THIS AGREEMENT

         Notwithstanding anything contained herein, this Agreement shall
         terminate when the Conditional Purchaser ceases to be under an
         obligation to pay the Transfer Price in respect of the Class A Notes by
         virtue of Clause 2.2(d) or (e) (including for the avoidance of doubt
         where it has satisfied its obligation to pay each such amount).

7.2      CONSEQUENCES OF TERMINATION OF THIS AGREEMENT

         Upon such termination in accordance with Clause 7.1 this Agreement
         shall terminate and be of no further effect and no party shall be under
         any liability to any other in respect of this Agreement, except that

                  transferred to it pursuant to this Agreement, have the rights
                  and obligations of a Conditional Purchaser hereunder and the

                  obligations hereunder have been transferred by it pursuant to

         covenant or agreement of any person contained in this Agreement shall
         be had against any shareholder, officer or director of the Issuer or
         the Conditional Purchaser, by the enforcement of any assessment or by
         any legal proceedings, by virtue of any statute or otherwise; it being
         expressly agreed and understood that this Agreement is a corporate
         obligation of the Issuer and the Conditional Purchaser expressed to be
         a party hereto and no personal liability shall attach or be incurred by
         the shareholders, officers, agents or directors of such person as such,
         or any of them, under or by reason of any of the obligations, covenants
         or agreements of the Issuer or the Conditional Purchaser contained in
         this Agreement, or implied therefrom, and that any and all personal
         liability for breaches by such person of any such obligations,
         covenants or agreements, either under any applicable law or by statute

         is hereby expressly waived by each person expressed to be a party
         hereto as a condition of and consideration for the execution of this
         Agreement; provided, however, that the foregoing shall not relieve any
         such person or entity of any liability they might otherwise have as a
         result of wilful misconduct or fraudulent actions or omissions taken by
         them.

         The provisions of this Clause 11.2 shall survive the termination of
         this Agreement.

12.      COUNTERPARTS

         This Agreement may be executed in any number of counterparts and by
         different parties hereto on separate counterparts each of which, when
         executed and delivered, shall constitute an original, but all the
         counterparts shall together constitute but one and the same instrument,
         provided, however, that this Agreement shall have no force or effect
         until it is executed by the last party to execute the same and shall be
         deemed to have been executed as delivered in the place where such last
         party executed this Agreement.

                                       14

         This Agreement shall be governed by and construed in accordance with
         English law.

13.2     JURISDICTION

         The courts of England are to have jurisdiction to settle any disputes
         which may arise out of or in connection with this Agreement and
         accordingly any legal action or proceedings arising out of or in
         connection with this Agreement ("PROCEEDINGS") may be brought in such
         courts. The parties to this Agreement hereby irrevocably submit to the
         jurisdiction of such courts and waive any objection to Proceedings in
         such courts whether on the ground of venue or on the ground that the
         Proceedings have been brought in an inconvenient forum. This submission
         is for the benefit of each of the parties to this Agreement and shall
         not limit the right of any of them to take Proceedings in any other
         court of competent jurisdiction nor shall the taking of Proceedings in
         any one or more jurisdictions preclude the taking of Proceedings in any
         other jurisdiction (whether concurrently or not).

14.      CONTRACTS (RIGHTS OF THIRD PARTIES) ACT 1999

         A person who is not a party to this Agreement shall have no rights
         under the Contracts (Rights of Third Parties) Act 1999 to enforce any
         terms of this Agreement but this does not affect any rights or remedy
         of any person which exists or is available apart from that Act.

In witness whereof, this Agreement has been entered into on the date stated at
the beginning.
