Page 18

CONFORMED COPY

Termination Event – Set off

7.2 Following the occurrence of a Termination Event due to any insolvency event affecting a Seller, each of the Master Purchaser, the Funding Agent and the Security Trustee shall be entitled without notice (but shall not be obliged) to set off any obligation which is due and payable by that Seller and unpaid against any obligation (whether or not matured) owed under any Transaction Document by the Master Purchaser or the Funding Agent (as the case may be) to that Seller regardless of the place of payment or currency of either obligation.

Termination by a Seller – merger

7.3 A Seller may terminate its agreement to sell Receivables to the Master Purchaser at any time by giving five Business Days’ notice in writing to the Master Purchaser and the Funding Agent provided that either:

(a) the business of such Seller is merged or amalgamated with the other Seller; or

Continuing Effect

7.4 The termination by a Seller of its agreement to sell Receivables to the Master Purchaser pursuant to Clause 7.3 above shall not affect any rights or obligations of the parties in relation to any Receivables purchased prior to such termination and the provisions of this Agreement shall continue to bind the parties to the extent and for so far and so long as may be necessary to give effect to such rights and obligations. The covenants, obligations and undertakings contained in this Agreement and the rights and remedies in this Agreement in respect of any representation, warranty or statement made under or in connection with this Agreement and the indemnification and other payment obligations in this Agreement shall continue and remain in full force and effect notwithstanding the termination of this Agreement.

8. REMEDIES FOR BREACH OF WARRANTY

Non-Conforming Receivables

8.1 If any representation or warranty set out in Part A of Schedule 1 insofar as it relates to the assignability, collectability, validity or enforceability of a Purchased Receivable or if any representation or warranty set out in Part B of Schedule 1 in respect of a Purchased Receivable proves to have been incorrect on the relevant Purchase Date and remains incorrect, or if the relevant Purchased Receivable has never existed (each affected Purchased Receivable being a Non-Conforming Receivable) the Relevant Seller, in respect of each Non-Conforming Receivable, shall treat the amount equal to the Outstanding Balance of the relevant Non-Conforming Receivable as a Deemed Collection and the Relevant Seller shall pay to the relevant Master Purchaser Account an amount equal to the Outstanding Balance of the relevant Non-Conforming Receivable on the next Settlement Date. Notwithstanding

Page 19

Master Receivables Purchase Agreement

CONFORMED COPY

the fact that the Deemed Collection shall be paid by the Relevant Seller on the next Settlement Date, for all other purposes including, without limitation, the calculation of the Daily Asset Base, the Deemed Collection shall be deemed to have been received as of the day such Non-Conforming Receivable arises. To the extent that a Seller has made a payment to the Master Purchaser in respect of a Non-Conforming Receivable in accordance with this Clause 8.1 and an actual Collection is subsequently received by the Master Purchaser in respect of such Non-Conforming Receivable, the Master Purchaser will pay to that Seller on the immediately succeeding Settlement Date, in accordance with the applicable Master Purchaser Priority of Payments and by way of refund of the payment made by the Seller pursuant to this Clause 8.1, an amount equal to the Collection so received in respect of such Non-Conforming Receivable.

Dilutions

8.2 If a Dilution occurs in respect of any Purchased Receivable, the Relevant Seller shall be deemed to have received a collection in an amount equal to each such Dilution and on the next Settlement Date shall pay to the relevant Master Purchaser Account an amount equal to such Dilution and the amount paid by the Relevant Seller pursuant to this Clause 8.2 shall be treated as a Deemed Collection in respect of the relevant Purchased Receivable. Notwithstanding the fact that the Relevant Seller shall make payment in respect of the Dilution on the next Settlement Date, for all other purposes including, without limitation, the calculation of the Daily Asset Base, the Dilution shall be deemed to have occurred as of the day such Dilution arises.

Means of remedying breach

8.3 For the avoidance of doubt, the payment by a Seller in full of the amount due in respect of any Purchased Receivable under Clause 8.1 or Clause 8.2 on the date on which it is due will remedy any breach or default by such Seller in respect of that Receivable or the relevant part thereof and the Master Purchaser and the Funding Agent shall not have any other right or remedy in respect of such breach or default.

Recoupment of Value Added Tax

8.4 For the purpose of ensuring recoupment of any value added tax forming part of a Purchased Receivable:

(a) all or part of which remains unpaid after the statutory period for purposes of claiming bad debt relief has elapsed; or

(b) the Outstanding Balance of which is, or would be, reduced, adjusted or cancelled by the Relevant Seller,

the Relevant Seller will use its reasonable endeavours to recover such value added tax to the extent that the Relevant Seller is legally entitled to claim a repayment of such value added tax (or the appropriate part thereof) from the appropriate tax authorities, and shall, upon receipt of any amount in respect of such value added tax, to the extent that the Master Purchaser has not already been fully compensated for the non-receipt of such part of the Purchased Receivable as is equal to the valued added tax charged

Page 20

Master Receivables Purchase Agreement

CONFORMED COPY

thereon, promptly remit the net amount not so compensated to the Master Purchaser and any such net amount will be paid into a Master Purchaser Account and treated as a Collection. The Relevant Seller will make such accounting write-offs and transfers and raise such credit notes as may be necessary or desirable for this purpose, and take all such other steps as may be reasonably requested by the Master Purchaser provided that the Relevant Seller shall not be required to take any steps which it reasonably considers will unduly prejudice its tax affairs. At the request of the Relevant Seller and whether or not any amounts are payable to the Master Purchaser under this Clause 8.4, the Master Purchaser may, or at such time as the Master Purchaser is fully compensated, will, reassign or re-transfer such Purchased Receivable to the Relevant Seller, who will accept such re-assignment or re-transfer of any such Purchased Receivable (for a nil or nominal consideration), solely for the purpose of facilitating recoupment of such value added tax.

9. PROTECTION OF MASTER PURCHASER, FURTHER ASSURANCE

Non Petition Undertaking

9.1 Notwithstanding any other provision of this Agreement, or the winding up of the Master Purchaser, no Seller will take any corporate action or other steps or legal proceedings for the winding up, dissolution or reorganisation or examination or for the appointment of a receiver, administrator, administrative receiver, trustee, liquidator, examiner, sequestrator or similar officer of the Master Purchaser or of any or all of the revenues and assets of the Master Purchaser nor participate in any ex parte proceedings nor seek to enforce any judgment against the Master Purchaser.

Further Assurance

9.2 Each Seller agrees that from time to time it will, at its own cost, promptly execute and deliver all instruments and documents, and take all further action as the Master Purchaser or the Funding Agent may reasonably request in order to perfect, protect or more fully evidence the Master Purchaser’s interest in the Purchased Receivables and any proceeds thereof.

Enforcement

9.3 Each Seller hereby irrevocably consents to the Master Purchaser (or the Funding Agent on its behalf) or the Security Trustee at any time after the occurrence of a Termination Event, for its own benefit commencing proceedings in the name of such Seller in respect of any of the Purchased Receivables.

Currency Indemnity

9.4 If any payment under this Agreement is made or fails to be satisfied in a currency (the payment currency) other than the currency in which such payment is expressed to be due (the contractual currency) then the Seller making such payment as a separate and independent obligation shall indemnify and hold harmless (on an after-Tax basis) the Master Purchaser to the extent that the amount of the payment actually received by the Master Purchaser when converted into the contractual currency by the Master Purchaser purchasing the contractual currency (with the sum received) falls short of the amount expressed to be due.

Page 21

Master Receivables Purchase Agreement

CONFORMED COPY

Payment to the Seller Accounts

9.5 Whenever any amount is due, owing or payable to a Seller under or in connection with this Agreement, payment of such sum in cleared funds into the relevant Seller Account, or as otherwise directed in writing by the Relevant Seller at least two Business Days before any such payment is due to be made, shall constitute a complete discharge of the Master Purchaser’s obligation to pay such amounts. For the purposes of this Clause 9.5, where an amount is payable in EUR, the reference to the Seller Account shall be construed as a reference to the relevant Seller EUR Account. Where an amount is payable in US$, the reference to the Seller Account shall be construed as a reference to the relevant Seller US$ Account and where an amount is payable in GBP, the reference to the Seller Account shall be construed as a reference to the relevant Seller GBP Account.

Appropriation of Payments

9.6 If a person owing a payment obligation in respect of a Purchased Receivable makes a general payment to the Relevant Seller on account both of a Purchased Receivable which the Master Purchaser has purchased or agreed to purchase and of any other moneys due for any reason whatsoever to the Relevant Seller and makes no apportionment between them then such payment shall be treated as though the person had appropriated it first to the Purchased Receivable which the Master Purchaser has purchased or agreed to purchase and the proceeds of or comprised in such payment up to the full amount due or to become due in respect of the Purchased Receivable shall accordingly be the property of the Master Purchaser and the Relevant Seller shall immediately and without deduction transfer that amount in accordance with Clause 4 (Collection of Receivables) of the Servicing Agreement and shall in the meantime hold such moneys as fiduciary agent for the Master Purchaser.

10. SECURITY TRUSTEE

The Security Trustee (for itself and in its capacity as trustee under the Master Purchaser Deed of Charge) has agreed to become a party to this Agreement in order to receive the benefit of the warranties, covenants, undertakings and indemnities expressed in its favour, for agreeing amendments to this Agreement and for the better preservation and enforcement of the Security Trustee’s rights under the Master Purchaser Deed of Charge. However, the Security Trustee shall not assume or incur any obligation or liability whatsoever to the other parties hereto by virtue of the provisions contained in this Agreement.

11. COUNTERPARTS

This Agreement may be executed in any number of counterparts, and by each party on separate counterparts. Each counterpart is an original, but all counterparts shall together constitute one and the same instrument. Delivery of a counterpart of this Agreement by e-mail attachment or telecopy shall be an effective mode of delivery.
