(b) undertakes with the Lender that whenever the Principal does not pay or discharge all or any part of the Principal’s Obligations when the same become due for payment or discharge, the Guarantor shall immediately on demand pay that amount as if it was the principal obligor; and

2.2 The Guaranteed Obligations include in the case of insolvency of the Principal, all sums which would at any time have been owing to the Lender by the Principal in respect of the Principal’s Obligations if such insolvency had commenced at the time when the Lender receives actual notice thereof and notwithstanding such insolvency.

2.3 The Guarantor’s liability under this Deed shall be as sole and primary obligor and not merely as surety and the Guarantor hereby waives all and any of its rights as surety which may at any time be inconsistent with any of the provisions of this Deed.

3. REPRESENTATIONS AND WARRANTIES

The Guarantor makes the representations and warranties set out in Schedule 2 to the Lender on the date of this Deed.

4. CONTINUING SECURITY

4.1 This Deed is a continuing security for all of the Principal’s Obligations and shall not be discharged by any intermediate discharge or payment of or on account of the Guaranteed Obligations or any of them or any settlement of accounts between the Lender and the Principal or any other person. No demand made by the Lender under this Deed shall prejudice or restrict the right of the Lender to make further demands.

4.2 If this Deed ceases for any reason to be a continuing security, this Deed shall relate to all the Guaranteed Obligations as at the date of such cessation, together with any monies advanced by the Lender to the Principal or liabilities incurred by the Principal to the Lender pursuant to the Promissory Note after the date of such cessation in either case pursuant to an obligation or commitment of the Lender entered into prior to the date of such cessation;

4.3 The Guarantor acknowledges and agrees that:

(a) this Deed is irrevocable; and

(b) it will not serve notice or take any other action to determine or revoke its obligations under this Deed as a continuing security; and

(c) service of notice by it to determine or revoke its obligations under this Deed or any other action taken to determine or revoke those obligations shall constitute a breach of the undertakings in this Deed for the purposes of Clause 2.1(c).

5. WAIVER OF DEFENCES

The obligations of the Guarantor under this Deed will not be affected by any act, omission, matter or thing which, but for this Clause 5, would reduce, release, prejudice or diminish any of its obligations under this Deed or prejudice or diminish those obligations in whole or in part (whether or not known to it or the Lender).

4

6. GUARANTOR INTENT

Without prejudice to the generality of Clause 5, the Guarantor expressly confirms that it intends that this Deed shall extend from time to time to any variation, increase, extension or addition (however fundamental and of whatsoever nature and whether or not more onerous) of or to the Promissory Note and/or any facility or amount made available under the Promissory Note provided the Guarantor is provided with advance written notice of any such change and consents to the extending (if applicable) of its obligations under this Deed.

7. AVOIDANCE OF PAYMENTS; REINSTATEMENT

7.1 Avoidance of Payments

Any discharge or release by the Lender of the Guarantor in respect of all or any part of the Guaranteed Obligations and any agreement between the Guarantor and the Lender concerning any such liabilities shall be void, and deemed to have been given or entered into by the Lender on the footing or express condition that it would be void, if any act or thing in reliance upon or on the faith of which the Lender gave such discharge or release or entered into that agreement shall be subsequently avoided by or in pursuance of any provision or rule of law.

7.2 Reinstatement

If any payment by the Principal or the Guarantor or any discharge, release or settlement given by the Lender (whether in respect of the obligations of the Principal or the Guarantor or any security for those obligations or otherwise) is avoided, adjusted or reduced as a result of insolvency:

(a) the liability of the Guarantor shall continue as if the payment, discharge, release, settlement, avoidance, adjustment or reduction had not occurred;

(b) the Lender shall be entitled to recover the value or amount of that security or payment from the Guarantor, as if the payment, discharge, release, settlement, avoidance, adjustment or reduction had not occurred; and

(c) the Lender shall be entitled to enforce this Deed subsequently as if such payment, discharge, release, settlement, avoidance, adjustment or reduction had not occurred and any such payment had not been made.

8. PAYMENTS

8.1 All payments by the Guarantor under this Deed shall be made to the Lender to its account at such office or such bank as it may notify to the Guarantor for this purpose.

8.2 Payments under this Deed to the Lender shall be made for value on the due date at such times and in such funds specified by the Lender as being customary at the time for the settlement of transactions in the relevant currency in the place for payment.

8.3 If a payment under this Deed is due on a day which is not a Business Day, the due date for that payment shall instead be the next Business Day in the same calendar month (if there is one) or the preceding Business Day (if there is not).

5

8.4 The Guarantor will pay all monies due under this Deed free and clear of and without deduction for or on account of any set-off or counterclaim or any and all present or future taxes, levies, imposts, charges, fees, deductions or withholdings. If any sums payable under this Deed shall be or become subject to any such deduction or withholding, the amount of such payments shall be increased so that the net amount received by the Lender shall equal the amount which, but for such deduction or withholding, would have been received by the Lender under this Deed.

8.5 If any payment to be made by the Guarantor under this Deed would attract a liability to tax in the hands of the Lender and if such payment were made by the Principal it would in the hands of the Lender either be tax free or attract a lesser liability to tax, then the Guarantor will concurrently pay to the Lender such additional amount as will compensate the Lender for such tax or increased tax.

9. POWERS OF THE LENDER

In the event of any proceedings in or analogous to insolvency of or concerning the Principal, the Lender may notwithstanding any payment made under this Deed approve and agree to accept any dividend or composition in respect of the whole or any part of the Principal’s Obligations in the same manner as if this Deed had not been given.

10. IMMEDIATE RECOURSE

10.1 The Guarantor waives any right it may have of first requiring the Lender (or any trustee or agent on its behalf) to make demand upon, proceed against or enforce any other rights or security or claim payment from or make or file any proof or claim in any insolvency proceedings relative to the Principal or any other person before claiming from the Guarantor under this Deed. This waiver applies irrespective of any law.

10.2 The Guarantor confirms to the Lender that the Lender need not advise the Guarantor of its dealings with the Principal or any default by the Principal of which the Lender may have notice.

11. DEFERRAL OF GUARANTOR’S RIGHTS

11.1 Until the Guaranteed Obligations have been irrevocably paid and discharged in full and the Lender is not under any obligation to grant or continue any loans to the Principal and unless the Lender otherwise directs, the Guarantor may not exercise any rights which it may have by reason of performance by it of its obligations under the Promissory Note to:

(a) demand or accept repayment in whole or in part of any indebtedness now or hereafter due to the Guarantor from the Principal or from any other person liable for that indebtedness;

(b) accept from the Principal either directly or indirectly any undertaking, obligation or security whereby the Guarantor or any person claiming through the Guarantor by endorsement, assignment or otherwise would or might on the insolvency of the Principal and to the prejudice of the Lender increase the proofs in such liquidation or diminish the assets distributable amongst the creditors of the Principal;

(c) make or enforce any claim (whether by way of set-off, counterclaim or otherwise) or right against the Principal or prove in competition with the Lender in respect of any payment under this Deed made by the Guarantor;

(d) claim or be entitled to claim, or have the benefit of, any set-off, counterclaim or proof against, or dividend, composition or payment by, the Principal or any co-guarantor in respect of any payment under this Deed made by the Guarantor;

6

(e) claim or prove in competition with the Lender in the insolvency of the Principal or any co-guarantor or have the benefit of or share in any payment or composition from the same but if so directed by the Lender, it will prove for the whole or any part of its claim in the insolvency of the Principal on terms that the benefit of such proof and all money received by it in respect thereof shall be held on trust for the Lender and applied in or toward discharge of the Guaranteed Obligations in such manner as the Lender shall deem appropriate;

(f) be indemnified or reimbursed by the Principal;

(g) claim or enforce any contribution from any other guarantor of all or part of the Guaranteed Obligations; and/or

(h) take the benefit (in whole or in part and whether by way of subrogation or otherwise) of any rights of the Lender under the Promissory Note or any document guarantee or security taken pursuant to, or in connection with, the Promissory Note / Principal’s Obligations by the Lender.

11.2 If the Guarantor receives any benefit, payment or distribution in relation to the rights specified in Clause 11.1 it shall hold on trust for the Lender that benefit, payment or distribution to the extent necessary to enable all amounts which may be or become payable to the Lender by the Principal under or in connection with the Guaranteed Obligations to be repaid in full and shall immediately pay or transfer the same to the Lender or as the Lender may direct.

11.3 The Guarantor waives all or any of its rights as surety which may be inconsistent with any provisions of this Deed.

11.4 The provisions of Clause 11.2 stating that a trust is created shall have effect only to the extent that such provisions do not constitute or create any charge and if they are so deemed to create a charge then the Guarantor agrees that a debt instead shall be due from them to the Lender in an amount equivalent to the benefit, payment or distribution received by it as referred to in Clause 11.2.

12. ADDITIONAL SECURITY

This Deed is in addition to and shall not merge with or otherwise prejudice or affect any contractual or other right or remedy or any other guarantee or security for the Guaranteed Obligations or any of them which are now or may hereafter be held by the Lender whether from the Guarantor or otherwise.

13. LIMITATIONS

This Deed does not apply to any liability to the extent that it would result in this Deed constituting unlawful financial assistance within the meaning of Section 82 of the Companies Act or any equivalent and applicable provisions under the laws of any Relevant Jurisdiction.

14. PARTIAL INVALIDITY

If, at any time, any provision of this Deed is or becomes illegal, invalid or unenforceable in any respect under any law of any jurisdiction, neither the legality, validity or enforceability of the remaining provisions nor the legality, validity or enforceability of such provision under the law of any other jurisdiction will in any way be affected or impaired.

7

15. REMEDIES AND WAIVERS

No failure to exercise, nor any delay in exercising, on the part of the Lender, any right or remedy under this Deed shall operate as a waiver, nor shall any single or partial exercise of any right or remedy prevent any further or other exercise or the exercise of any other right or remedy.
