unless and to the extent that any of them arises as a result of: (i) the fraud, bad faith, negligence or wilful default of an Indemnified Person; or (ii) from a material breach of the terms of this Agreement by Investec; or (iii) from a contravention by an Indemnified Person of the regulatory system (as defined in the handbook and rules of the Financial Services Authority) or breach or contravention of the provisions of the FSMA or the AIM Rules; or (iv) is of such a nature that liability may not be excluded pursuant to the FSMA.

9.4

If Investec becomes aware of any claim made or threatened within the scope of the indemnity set out in this Clause 9, Investec shall promptly notify the Company thereof and shall thereafter (subject to the Indemnified Person being indemnified and secured to their reasonable satisfaction by the Company against all costs, charges, damages and expenses the Indemnified Person may suffer or incur as a result of so doing), subject to the requirements (if any) of the Indemnified Person’s insurers, consult with the Company regarding the Indemnified Person’s conduct of the Claim and shall provide the Company with such information and copies of such documents relating to the claim as the Company may reasonably require provided that the Indemnified Person shall not be under any obligation to take into account any requirements of the Company in connection with such conduct nor to provide the Company with a copy of any document which is, or in the reasonable opinion of the Indemnified Person’s advisers, is likely to be privileged in the context of the claim.

(a)

the Company in good faith considers a relevant document to be subject to a bona fide duty of confidentiality owed by it to a third party or to be privileged in the context of any litigation by the Company against the Indemnified Person (or vice versa) connected with the claim; or

(b)

it would prejudice any insurance cover to which the Company may from time to time be entitled.

9.6

The Company agrees that it will not without the prior written consent of Investec settle or compromise or consent to the entry of any judgement with respect to any pending or threatened claim in respect of which indemnification may be sought by any Indemnified Person under this Clause 9 (whether or not the Indemnified Person is an actual or potential party to such claim) unless such settlement, compromise or consent includes an unconditional release of the Indemnified Person from all liability arising out of such claim.

Termination

11.1

If at any time before Admission:

(a)

the Company fails, in any material respect, to comply with any of its obligations under this Agreement; or

(b)

it comes to the notice of Investec that any statement contained in the Presentation has become untrue, incorrect or misleading in any respect which Investec considers in good faith to be material in the context of the Placing or that any matter which Investec considers to be material in the context of the Placing has arisen which would, if the Placing were made at that time, constitute a material omission therefrom; or

(c)

in the reasonable opinion of Investec any of the Warranties was not at the date of this Agreement true and accurate in any material respect in the context of the Placing by reference to the facts subsisting at the time when the notice referred to below is given; or

(d)

in the reasonable opinion of Investec any of the Warranties by reference to the circumstances prevailing from time to time has ceased to be true and accurate in any material respect in the context of the Placing by reference to the facts subsisting at the time when the notice referred to below is given.

Investec may in its absolute discretion by notice in writing to the Company prior to Admission terminate its obligations under this Agreement (save to the extent specified in Clause 13).

11.2

If prior to Admission there happens, develops or comes into effect:

(a)

a general moratorium on commercial banking activities in London declared by the relevant authorities or a material disruption in commercial banking or securities settlement or clearance services in the United Kingdom or the US; or

(b)

the outbreak or escalation of hostilities or acts of terrorism involving the United Kingdom or the US or the declaration by the United Kingdom or the US of a national emergency or war; or

(c)

any other occurrence of any kind which (by itself or together with any other such occurrence) in Investec’s reasonable opinion is likely to materially and adversely affect the market’s position or prospects of the Group taken as a whole; or

(d)

any other crisis of international or national effect or any change in any currency exchange rates or controls or in any financial, political, economic or market conditions

which, in any such case, in Investec’s reasonable opinion is materially adverse to the success of the Placing and Admission and distribution of the Placing Shares. Then in any such case Investec may, after having to the extent practicable in the circumstances consulted with the Company, give notice in writing to the Company prior to Admission to rescind this Agreement without incurring any liability to the other parties to this Agreement or any of them.

12.

Continuing Obligations

12.1

The Company undertakes to Investec that except for the release of the Press Announcements in the agreed form or as may be expressly required by the London Stock Exchange or any applicable laws whether of England or elsewhere, or the rules of any other regulatory body having jurisdiction, neither it nor any of its subsidiaries nor any person on its or their behalf will at any time prior to Admission make any public announcement, public statement or public communication regarding the Company or any subsidiary or associate of the Company, whether in response to enquiries or otherwise, without the prior written consent of Investec, such consent not to be unreasonably withheld or delayed. Any announcement, statement or communication which prior to Admission the Company is required to make by the London Stock Exchange or any other regulatory authority or under any applicable laws or by any provision of this Agreement shall not be released unless the contents and manner of making thereof have first been approved by Investec, such approval not to be unreasonably withheld or delayed. Any such consent or approval shall not constitute a waiver of a breach of any of the Warranties unless expressed to do so.

12.2

The Company and Investec agree that the terms of the Nominated Adviser and Broker Agreement dated 19 July 2005 between the Company, the Directors and Investec be amended such that the shareholder majority required to waive the pre-emption right granted to Investec be reduced from 75% to 50%. Accordingly it is agreed that the definition of “Shareholder Majority” contained in Schedule 2 of the said agreement be amended to refer to “holders of 50% of the voting rights at the relevant time”, and the existing definition be deleted.

13.

Effect of Termination

If the obligations of Investec under this Agreement (save to the extent specified in this Clause 13) shall be terminated or rescinded pursuant to Clause 11, no party shall have any claim against any other party hereto for compensation, costs, damages or otherwise, save that the provisions of Clauses 1, 7.3, 7.4, 9, 10, 16, 17, 18, 19, 20 and 21 shall continue to apply notwithstanding such termination and Clause 12.1 shall continue to apply for a period of 30 days from the date of such termination insofar as any public announcement, statement or communication refers to Investec.

14.

Withholding and Grossing-Up

14.1

All sums payable to Investec under this Agreement shall be paid free and clear of all deductions or withholdings unless the deduction or withholding is required by law, in which event the relevant person shall pay such additional amount as shall be required to ensure that the net amount received by Investec will equal the full amount which would have been received by it had no such deduction or withholding been made.

14.2

If HM Revenue & Customs or any other tax authority brings into charge to tax (or into any computation of income, profit or gains for the purposes of any charge to tax) any sum payable to Investec under this Agreement (other than the fees and commissions due under Clause 7.1), then the person liable to make such payment shall pay such additional amount as shall be required to ensure that the total amount paid, less the tax chargeable thereon (or that would be so chargeable but for the availability of relief in respect of that charge to tax), is equal to the amount that would otherwise be payable to Investec under this Agreement (additional payments being made on demand of Investec).

14.3

If, on payment of an additional amount to Investec under Clause 14.1 or 14.2 Investec determines that it has received or been granted (and has derived full use and benefit from) a credit against, relief or remission for, or repayment of, any tax in respect of or calculated with reference to the additional amount paid, Investec shall, to the extent that it can do so without prejudice to the retention of such credit, relief, remission or repayment, pay to the Company such amount as Investec shall, acting reasonably, determine to be the proportion of such credit, relief, remission or repayment as will leave Investec after such payment in the same after tax position it would have been in (after taking into account all reasonable expenses incurred in determining or, if necessary, claiming the appropriate credit, relief, remission or repayment) if no additional amount has been required to be paid. Provided always that:

(a)

Investec’s determination of any amount payable under this Clause 14.3 and the date by which it shall be paid shall be final and binding (subject to Investec’s right to adjust the amount determined should the initial determination prove to be correct);

(b)

Investec shall have absolute discretion as to the order and manner in which it employs or claims tax credits and allowances available to it and generally as to the conduct of its tax affairs; and

(c)

Investec shall not be obliged to disclose any information regarding its tax affairs or tax computations.

15.

16.

Assignment

The benefit of this Agreement may not be assigned or charged by the Company or any of the Warrantors without the prior written consent of Investec but subject thereto this Agreement shall be binding upon and ensure for the benefit of the respective executors, administrators, heirs, successors and assignees of the parties.
