2.01 In consideration of the credit established by the Bank under the Finance Contract, the Guarantor hereby irrevocably and unconditionally guarantees to the Bank the due and punctual payment and performance of all present and future obligations and liabilities of the Borrower (whether solely or jointly with one or more persons and whether as principal or as surety or in some other capacity) to the Bank under the Finance Contract (collectively, the "Liabilities", and each, a "Liability") and the payment of all Guaranteed Sums in accordance with the Finance Contract. The Guarantor undertakes that, if the Borrower should fail to pay any Guaranteed Sum to the Bank in accordance with the Finance Contract, whether upon the normal due date, upon acceleration or otherwise, the Guarantor shall unconditionally pay the sum in question to the Bank on demand as if the Guarantor were the principal obligor, in the currency specified in the Finance Contract and to the account specified in the demand.

For the purposes of this Guarantee, a "Guaranteed Sum" means any and all principal, interest, commission, liquidated damages, charge, indemnity, expense or other sum which may from time to time become due by the Borrower to the Bank under or pursuant to the Finance Contract and any other sum due from time to time by the Borrower in connection with any advance or credit extended or to be extended pursuant to the Finance Contract (in each case, whether actual or contingent, whether owed jointly or severally and whether owed as principal or surety or in any other capacity and references to the Guaranteed Sum includes references to any part of it).

The Guarantor further agrees and undertakes to pay interest to the Bank at the rate and on the terms specified in Article 3.02 (Interest on overdue sums) of the Finance Contract for payment of overdue sums on all sums demanded under this Guarantee (before and after any judgement) from the date of the Bank's demand until the date of receipt of such sum by the Bank, provided that there shall be no double counting with the Finance Contract.

2.02 The obligations of the Guarantor hereunder are those of a primary obligor and not merely those of a surety. Neither the obligations of the Guarantor under this Guarantee nor the rights, powers or remedies conferred upon the Bank in this Guarantee or by law shall be impaired, discharged or otherwise affected by reason of:

(a) any illegality, invalidity, ineffectiveness or unenforceability in or of the terms of the Finance Contract or of any other security for the Liabilities;

(b) any disability, incapacity or lack of power, authority or legal personality or change in status or constitution of the Borrower, the Bank or any other person;

(c) any winding-up, dissolution, administration, re-organisation, liquidation, insolvency or other similar procedure in respect of the Borrower or any other person or any change in the status, function, control or ownership of the Borrower or of any other person or the claiming, proving for, accepting or transferring any payment in respect of the Guaranteed Sum in any winding-up, dissolution, administration, re-organisation, liquidation, insolvency or composition of the Borrower or any other person or abstaining from so claiming, proving for, accepting or transferring;

(d) any time or other indulgence agreed or granted by the Bank or any arrangement entered into or composition accepted by the Bank, varying the rights of the Bank under the Finance Contract or any security arrangement;

(e) any release of the Borrower or any other person under the terms of any composition or arrangement with any creditor of any member of the Group;

(g) any other guarantee or Security Interest which the Bank now has or may hereafter acquire with respect to the Borrower's or any other person’s obligations under the Finance Contract or any related agreement;

(h) any amendment to, or any variation, waiver, assignment, novation, supplement, extension, restatement, replacement or release of (in each case, however fundamental and whether or not more onerous), the Finance Contract or any other document or security (including, without limitation, any change in the purpose, time, manner or place of payment, any extension of or any increase in any facility or the addition of any new facility under the Finance Contract or other document or security), the Guaranteed Sums or the Liabilities or any of them or any Security Interest (or of any person thereunder) held by the Bank in respect thereof;

(i) the taking, acceptance, variation, compromise, exchange or renewal of any Security Interest or any total or partial failure to take or perfect any security proposed to be taken in respect of any Guaranteed Sums or Liabilities or any total or partial failure to realise the value of, or any surrender, release, discharge, exchange or substitution of, any Security Interest held by the Bank in respect of any Guaranteed Sum or Liabilities or any non-presentation or non-observance of any formality or other requirement in respect of any instrument; or

(j) any other act, event, omission or circumstance, which, but for this Article 2.02, might otherwise discharge, impair or otherwise affect any of the obligations of the Guarantor contained in this Guarantee or any of the rights, powers or remedies conferred upon the Bank by this Guarantee or by law,

it being the intent of the Guarantor that its liability to the Bank under this Guarantee shall be absolute and unconditional under any and all circumstances and shall not be discharged except by payment in full of the Guaranteed Sums and the satisfaction of the Liabilities.

The payment or performance of any of the Liabilities or Guaranteed Sums shall continue to be effective or be reinstated, as the case may be, if at any time any payment or performance of the Liabilities or the Guaranteed Sums is rescinded or must otherwise be returned by the Bank upon the insolvency, bankruptcy or reorganization of the Borrower or of the Guarantor or otherwise, all as though such payment or performance had not been made.

2.03 It is the intent of this Guarantee that the Bank be fully indemnified for the complete payment and performance of the Liabilities and the Guaranteed Sums. As an independent, continuing and primary obligation additional to and separate from those set out in Articles 2.01 and 2.02, and without prejudice to the validity or enforceability of those obligations, the Guarantor unconditionally and irrevocably undertakes (as a primary obligor and not merely as surety) that, if any Guaranteed Sum should not be recoverable from the Guarantor under Article 2.01 for whatsoever reason (including as a result of the Finance Contract or any of the Guaranteed Sums being or becoming void, voidable, unenforceable or ineffective as against the Borrower for any reason whatsoever), and whether or not the reason may have been known to the Bank or any other person at any material time, the Guarantor shall, upon first written demand by the Bank, and as if the Guarantor were a sole and independent obligor, fully indemnify, compensate and hold harmless the Bank by way of a full indemnity for all costs, losses, damages, expenses, claims or liabilities resulting from: (a) the failure of the Borrower to duly and punctually make payment of any Guaranteed Sum in the amount and currency provided for by or pursuant to the Finance Contract, whether upon the normal

5

due date, upon acceleration or otherwise; (b) any Liability being or becoming void, voidable, unenforceable or ineffective as against the Borrower for any reason whatsoever, whether or not known to the Bank, the amount of such loss being the amount which the Bank would have been entitled to recover from the Borrower but for such Liability being or becoming void, voidable, unenforceable or ineffective as against the Borrower; or (c) any act or omission of the Bank in connection with the enforcement of its rights or remedies against the Borrower or the Guarantor.

2.04 This Guarantee is a continuing security and the obligations of the Guarantor under this Guarantee shall constitute and be continuing obligations notwithstanding any settlement of account or other matter or thing whatsoever, and shall endure until all Guaranteed Sums have been fully paid or discharged and shall not be released or discharged by any intermediate payment or settlement of the Guaranteed Sums or of any of them or by any intermediate satisfaction of all or any of the obligations of the Borrower in relation to any of the Liabilities. This Guarantee shall continue in full force and effect until final payment in full of all amounts owing by the Borrower in respect of the Liabilities and total satisfaction of all the Borrower's actual and contingent obligations in relation to the Liabilities. No payment or discharge which may be avoided under any enactment relating to insolvency, bankruptcy, voluntary or involuntary dissolution, winding up, merger or amalgamation of the Borrower, the Guarantor or any other person, no payment or discharge made or given which is subsequently avoided and no release, return, cancellation or discharge of this Guarantee given or made or any other agreement reached between the Bank and the Guarantor on the faith of any payment or discharge aforesaid shall constitute discharge of the Guarantor under this Guarantee or prejudice or affect the Bank's right to recover from the Guarantor to the full extent of this Guarantee, and any such discharge, release, return, cancellation or agreement shall be deemed always to have been void. This is a guarantee of payment not a deficiency guarantee. The originals of this Guarantee which are in the possession of the Bank shall remain the property of the Bank after any release, cancellation or discharge of this Guarantee.

2.05 Any money received, recovered or realised in connection with this Guarantee (including the proceeds of any conversion of currency) may be placed by the Bank in its discretion to the credit of a suspense account, with a view to preserving the right of the Bank to prove for the whole of the claims against the Borrower or may be applied by the Bank in or towards satisfaction of such of the Guaranteed Sums as the Bank in its absolute discretion may from time to time determine; provided, however, that if any such money, being freely disposable by the Bank, is not applied towards satisfaction of the Guaranteed Sums for which payment of the money was made hereunder, the Guarantor's responsibility in respect of the Guaranteed Sums shall be discharged to the extent of such payment.

2.06 The Guarantor agrees that until all the Guaranteed Sums have been irrevocably fully paid or discharged and so long as the Borrower is under any actual or contingent obligations in respect of the Liabilities, the Guarantor shall:

(a) not exercise any rights which it may at any time have by reason of performance by it of its obligations under this Guarantee or by reason of any amount being payable, or liability arising, under this Guarantee to:

(i) be indemnified by the Borrower or to receive any collateral from the Borrower; and/or

(ii) claim any contribution from any other guarantor of any of the Liabilities or Guaranteed Sums; and/or

(iii) take the benefit (in whole or in part and whether by way of subrogation or otherwise) of any rights of the Bank in respect of any of the Liabilities or Guaranteed Sums or of any other security taken by the Bank pursuant

6

to, or in connection with, any of the Liabilities or Guaranteed Sums; and/or

(iv) bring any legal or other proceedings for an order requiring the Borrower to make any payment, or perform any obligation, in respect of which the Guarantor has given a guarantee, undertaking or indemnity pursuant to this Guarantee; and/or

(v) exercise any right of set-off against the Borrower; and/or

(vi) claim or prove as a creditor of the Borrower in competition with the Bank;

(b) not seek to enforce any obligation owed to it by the Borrower which arises by virtue of the discharge by the Guarantor of its obligations hereunder;

(c) pay to the Bank all dividends or distributions, in bankruptcy, insolvency, receivership, liquidation, winding up or otherwise received by it from or for the account of the Borrower in respect of any obligation referred to in paragraph (b) above; the Bank shall apply such sums to reduce the outstanding Guaranteed Sums in such sequence as it may decide;

(d) have no right of subrogation to the rights of the Bank under the Finance Contract or any related security arrangement;

(e) comply with the terms of and do all that is necessary to maintain in full force and effect all authorisations, approvals, licences and consents required in or by the laws and regulations of England and Wales to enable the Guarantor lawfully to enter into and perform its obligations under this Guarantee and to ensure the legality, validity, enforceability and admissibility in evidence in England of this Guarantee;

(f) not take any action which would cause any of the representations made in Article 7 below to be untrue at any time during the continuation of this Guarantee; and

(g) notify the Bank of the occurrence of any event which results in or may reasonably be expected to result in any of the representations made in Article 7 below being untrue when made or when deemed to be repeated.

2.07 If the Guarantor receives any benefit, payment or distribution in relation to any of the rights set out in Article 2.06(a)(i) to (vi), the Guarantor shall hold on trust for the Bank that benefit, payment or distribution to the extent necessary to enable all amounts which may be or become payable to the Bank by the Borrower and/or the Guarantor under or in connection with the Finance Contract and/or this Guarantee to be repaid in full and shall promptly pay or transfer the same to the Bank as the Bank may direct.

2.08 The Guarantor acknowledges: (i) that it has entered into this Guarantee on the basis of its own assessment of the Borrower and any security provided, and (ii) that it has not been induced to enter into this Guarantee by any representation made by the Bank. The Bank is not obliged to report to the Guarantor on the financial position of the Borrower or of any other guarantor or on any security provided. The Bank shall have no liability for granting or disbursing the Loan, for cancelling or suspending, or not cancelling or suspending the Credit or for demanding or not demanding prepayment under the Finance Contract.

2.09 The obligations of the Guarantor contained in this Guarantee shall be in addition to, independent of and in no way prejudiced by any other security or any other guarantee that the Bank holds or may at any time hold in relation to any of the Liabilities or the Guaranteed Sums.

7

2.10 The Bank may set off any matured obligation due from the Guarantor under this Guarantee against any obligation (whether or not matured) owed by the Bank to the Guarantor regardless of the place of payment, booking branch or currency of either obligation. If the obligations are in different currencies, the Bank may convert either obligation at a market rate of exchange in its usual course of business for the purpose of the set-off. If either obligation is unliquidated or unascertained, the Bank may set off in an amount estimated by it in good faith to be the amount of that obligation.

ARTICLE 3

Enforcement of Guarantee

3.01 A certificate of the Bank as to any default by the Borrower in the payment of any Guaranteed Sum shall be conclusive against the Guarantor save in the event of a proven error.

3.02 The Guarantor undertakes to pay all sums due hereunder in full, free of set‑off or counterclaim. This Guarantee may be enforced by the Bank upon provision of a statement of the reason for the demand.

3.03 The Bank shall not be obliged before exercising any of the rights, powers or remedies conferred upon it in respect of the Guarantor by this Guarantee or by law to:

(c) make or file any claim or proof in a winding-up or dissolution of the Borrower;

(d) enforce or seek to enforce any security taken in respect of any of the obligations of the Borrower in respect of the Guaranteed Sums or Liabilities; or

(e) have recourse to any other guarantee,

and the Guarantor waives any right it may have of first requiring the Bank (or any trustee or agent on its behalf) to proceed against or enforce or exhaust any other rights or security or claim payment from any person before claiming from the Guarantor under this Guarantee. This waiver applies irrespective of any law or any provision of the Finance Contract to the contrary.

3.04 Where the Bank makes any demand hereunder, the Guarantor may pay to the Bank all outstanding Guaranteed Sums, including sums arising under Article 3.02 (Interest on overdue sums) of the Finance Contract, in settlement of its obligations hereunder.
