However, the Security Agent shall not exercise such power of sale until the Enforcement Date has occurred, or a Receiver has been appointed, but this provision shall not affect a purchaser or require him to ask whether a demand or appointment has been made. 12.3 Powers of Security Agent to Grant Leases: The statutory powers of sale, leasing and accepting surrenders exercisable by the Security Agent by virtue of this Debenture are extended so as to authorise the Security Agent (whether in its own name or that of the Charging Company concerned) to grant a lease or leases of any Land vested in a Charging Company or in which it has an interest, with such rights relating to other such Land, and containing such covenants on the part of such Charging Company, and generally on such terms and conditions, as the Security Agent shall think fit. 12.4 Power to Sever Fixtures: The statutory power of sale exercisable by the Security Agent is extended so as to authorise the Security Agent to sever any fixtures from Land and sell them separately. 12.5 Third Parties not to be concerned with Validity of Demand: No person dealing with the Security Agent or any Receiver, its agents or brokers, shall be concerned to enquire whether this Debenture has become enforceable, or whether any power exercised or purported to be exercised has become exercisable, or whether any Secured Sums remain due upon this Debenture, or as to the necessity or expediency of any stipulations and conditions subject to which the sale of any Assets shall be made, or otherwise as to the propriety or regularity of the sale of any Asset, or to see to the application of any money paid to the Security Agent or such Receiver, or its agents or brokers, and each such dealing shall be deemed to be within the powers hereby conferred and to be valid and effectual accordingly. 12.6 Exclusion of liability: The Security Agent shall not be liable (save in the event of its gross negligence or wilful misconduct) for: (a) any loss arising out of such sale or other disposal of any of the Securities or the exercise of or failure to exercise any of the Security Agent's powers of sale over any Securities under this Debenture, however caused and whether or not a better price could or might have been obtained by deferring or advancing the date of such sale or other disposal and the Security Agent shall not be liable to account as mortgagee in possession for any of the Securities; or (b) any neglect or default to pay any call or instalment or to accept any offer or to notify the relevant Charging Company of any matter or for any other loss of any nature whatsoever in connection with any of the Securities. 13. OPENING OF NEW ACCOUNTS 13.1 Ruling off Accounts: On receiving notice that any Charging Company has encumbered or disposed of any of its Assets, the Security Agent and/or any Beneficiary may rule off such Charging Company's account or accounts and open a new account or accounts with such Charging Company. 13.2 Credits not to reduce Indebtedness: If the Security Agent or any Beneficiary does not open a new account or accounts immediately on receipt of such notice, it shall nevertheless be treated as if it had done so at the time when it received such notice and as from that time all payments made by such Charging Company to the Security Agent or such Beneficiary shall be treated as having been credited to such new account or accounts and shall not operate to reduce the amount owing from such Charging Company to the Security Agent or such Beneficiary at the time when it received such notice. 14. APPOINTMENT AND POWERS OF A RECEIVER 14.1 Appointment of Receiver: At any time: (a) on or after the Enforcement Date; or (b) if so requested by the Primary Borrower and/or any Charging Company in respect of its own Assets; the Security Agent may appoint by writing any person or persons to be a receiver and manager or receivers and managers of all or any part of the Assets of the Primary Borrower and/or such Charging Company (as the case may be). 14.2 Power of Receivers Joint and Several: Where more than one Receiver is appointed, they shall have power to act separately unless the Security Agent shall in the appointment specify to the contrary. 14.3 Security Agent to Determine Remuneration of Receiver: The Security Agent may from time to time determine the remuneration of the Receiver. 14.4 Removal of Receiver: The Security Agent may (subject to Section 45 of the Insolvency Act 1986) remove the Receiver from all or any of the Assets of which he is the Receiver. 14.5 Further Appointment: Such an appointment shall not preclude (i) the Security Agent from making any subsequent appointment of a Receiver over all or any Assets over which a Receiver has not previously been appointed or has ceased to act, or (ii) a Receiver, while continuing to act, consenting to the appointment of an additional Receiver to act with him. 14.6 Receiver to Act as Agent: The Receiver shall be the agent of the Charging Company concerned (which shall be solely liable for his acts, defaults and remuneration) unless and until such Charging Company goes into liquidation, after which he shall act as principal and shall not become the agent of the Security Agent or the Beneficiaries. 14.7 Powers of Receiver: The Receiver shall have and be entitled to exercise in relation to the Charging Company concerned all the powers set out in Schedules 1 and 2 to the Insolvency Act 1986 and in particular, by way of addition and without limiting such powers (and without prejudice to the powers of the Security Agent and the Beneficiaries), the Receiver shall have power: (a) to take possession of, collect and get in all or any part of the Assets of the relevant Charging Company and to take and defend any proceedings (including proceedings for its winding up or proceedings by way of arbitration) in its name or otherwise as he shall think fit; (b) to carry on or concur in carrying on the business of the relevant Charging Company and raise money from any Beneficiary or others without security or on the security of all or any of its Assets; (c) to sell or concur in selling (where necessary with the leave of the Court), lease or concur in leasing, licence or concur in licensing, grant options over and, without the need to observe any of the provisions of Sections 99 and 100 of the Law of Property Act 1925, let or concur in letting and to terminate or to accept surrenders of leases, licences or tenancies of all or any of the Assets of the relevant Charging Company in such manner and generally on such terms and conditions as he shall think fit in his absolute and unfettered discretion and any such sale or disposition may be for cash, debentures, securities or other valuable consideration (in each case payable in a lump sum or by instalments) and to carry any such transactions into effect in the name of and on behalf of such Charging Company; (d) to promote the formation of a Subsidiary or Subsidiaries of the relevant Charging Company with a view to such Subsidiary or Subsidiaries purchasing, leasing, licensing or otherwise acquiring interests in all or any of the Assets of such Charging Company; (e) to arrange for such Subsidiary or Subsidiaries to trade or cease to trade as the Receiver may think fit from time to time; (f) to sever any fixtures from the Land of which they form part; (g) to exercise all voting and other rights attaching to Securities owned by the relevant Charging Company; (h) to arrange for the purchase, lease, licence or acquisition of all or any Assets of the relevant Charging Company by any such Subsidiary on a basis whereby the consideration may be for cash, shares, debentures, loan stock, convertible loan stock or other securities, shares of profits or sums calculated by reference to profits or turnover or royalties or licence fees or otherwise, whether or not secured on the assets of such Subsidiary and whether or not such consideration is payable or receivable in a lump sum or by instalments over such period as the Receiver may think fit; (i) to make any arrangement or compromise with the Security Agent or any Beneficiary as he shall think fit; (j) to make and effect all repairs, renewals and improvements to the Assets of the relevant Charging Company and to effect, renew or increase insurances on such terms and against such risks as he shall think fit; (k) to appoint managers, officers and agents for the above purposes at such salaries as the Receiver may determine; (l) to call up all or any portion of the uncalled capital of the relevant Charging Company; (m) to redeem any prior Security Interest and to settle and pass the accounts of the encumbrancer and any accounts so settled and passed shall (subject to any manifest error) be conclusive and binding on the relevant Charging Company and the money so paid shall be deemed an expense properly incurred by the Receiver; (n) to pay the proper administrative charges of the Security Agent and/or the Beneficiaries in respect of time spent by their agents and employees in dealing with matters raised by the Receiver or relating to the receivership of the relevant Charging Company; (o) to commence and/or complete any building operations upon any freehold or leasehold Land of the relevant Charging Company and to apply for and obtain any planning permissions, building regulation consents or licences in each case as he may in his absolute discretion think fit; (p) to vary the terms of the leases of any such freehold and leasehold Land; (q) to take all steps necessary to effect all registrations, renewals, applications and notifications as the Receiver will in his discretion think prudent to maintain in force or protect any of the relevant Charging Company's Intellectual Property Rights; (r) to do all such other acts and things as may be considered by the Receiver to be incidental or conducive to any of the above matters or powers or otherwise incidental or conducive to the preservation, improvement or realisation of the relevant Assets. 14.8 No Obligation to Account as Mortgagee in Possession: Neither the Security Agent nor any Beneficiary nor the Receiver shall be liable to account as mortgagee in possession or otherwise for any money not actually received by it or him respectively. 14.9 Third Parties: A person dealing with the Receiver in good faith and for full value shall not be concerned to enquire whether the Receiver is validly appointed or acting within his powers. Neither the Security Agent nor any Beneficiary nor the Receiver shall be liable to account as mortgagee in possession or otherwise for any money not actually received by it or him respectively, whether by way of payment, set-off, counterclaim or otherwise. 14.10 Section 109, Law of Property Act 1925: Section 109 of the Law of Property Act 1925 shall not apply to this Debenture. 15. POWER OF ATTORNEY 15.1 Power of Attorney: Each Charging Company by way of security hereby irrevocably appoints the Security Agent (whether or not a Receiver has been appointed) and any Receiver separately the attorney of such Charging Company (with full power to appoint substitutes and to delegate) for such Charging Company, in its name and on its behalf, and as its act and deed or otherwise, at any time to execute and deliver and otherwise perfect any agreement, assurance, deed, instrument or Document, perform any act or give any instructions in relation to Securities under the rules and practices of a Relevant System or otherwise, which may be required of such Charging Company under and in accordance with the terms of this Debenture and which such Charging Company has failed to do within 14 days of being notified by the Security Agent that it is required, or (on or after the Enforcement Date) as may be deemed by such attorney necessary or desirable for any purpose of this Debenture or to enhance or perfect the security intended to be constituted by it or to convey or transfer legal ownership of any Assets. 15.2 Ratification: Without prejudice to the generality of the provisions contained in clause 15.1 (Power of Attorney), each Charging Company hereby covenants with the Security Agent and separately with any Receiver that if required so to do such company will ratify and confirm: (a) all transactions entered into by it or (as the case may be) them at its or (as the case may be) their instance in the proper exercise of its or (as the case may be) their powers in accordance with this Debenture; and (b) all transactions entered into by it or (as the case may be) them in signing, sealing, delivering and otherwise perfecting any assignment, mortgage, charge, security, deed, assurance, document or act as aforesaid; and each Charging Company irrevocably acknowledges and agrees that such power of attorney is (inter alia) given to the Security Agent, or as the case may be, the Receiver or both, to secure the performance of these obligations owed to him or them by the Charging Companies. 16. ADJUSTMENT OF ACCOUNT If the state of account between the Security Agent or any Beneficiary and a Company by reference to which any Secured Sums are calculated for the purposes of this Debenture requires adjustment at any time because of any claim made against the Security Agent or such Beneficiary by an officeholder (within the meaning of Section 234 of the Insolvency Act 1986) then, notwithstanding any other provision of this Debenture: (a) such Company's liability to the Security Agent or such Beneficiary will be correspondingly adjusted; and (b) the Security Agent or such Beneficiary may treat any release or settlement made by it with such Company or any Charging Company before any such adjustment is required as being of no effect; and (c) the Security Agent or such Beneficiary may recover from such Company or any Charging Company such sum as will place the Security Agent or such Beneficiary in the same position as if such release or settlement had not been made. If any claim is made against the Security Agent or any Beneficiary under any insolvency law, the Security Agent or such Beneficiary may agree the claim or settle it on any terms it chooses without asking for the relevant Company's or any Charging Company's agreement. If the Security Agent or such Beneficiary does agree or settle the claim, the Primary Borrower will be liable under this Debenture as if a court order had been made containing the terms which the Security Agent or Beneficiary have agreed. The Primary Borrower will be responsible for all costs and expenses which the Security Agent or such Beneficiary properly incurs in defending such a claim. 17. OTHER POWERS EXERCISABLE BY THE SECURITY AGENT 17.1 Security Agent may Exercise Receiver's Powers: All powers of the Receiver conferred by this Debenture may be exercised by the Security Agent following demand by the Security Agent whether as attorney of the Charging Companies or otherwise and whether or not the Receiver shall have been appointed and so that clause 14.7(m) (Powers of Receiver) shall be read and construed as if the words "be charged on the Assets of the relevant Charging Company" were substituted for the words "be deemed an expense properly incurred by the Receiver." 17.2 Security Agent Empowered to receive Book Debts: The Security Agent or any manager or officer of the Security Agent is hereby irrevocably empowered to receive all book debts and other debts and claims which may be assigned to the Security Agent pursuant to clause 7 and on payment to give an effectual discharge for them and on non-payment to take and institute (if the Security Agent in its sole discretion so decides) all steps and proceedings either in the name of the relevant assignor or in the name of the Security Agent for their recovery and also to agree accounts and to make allowances and to give time to any surety. The relevant assignor hereby undertakes to ratify and confirm whatever the Security Agent or any manager or officer of the Security Agent shall do or purport to do under this clause 17. 17.3 Security Agent not obliged to take action relating to Book Debts: The Security Agent shall have no liability or responsibility to any Charging Company arising out of the exercise or non-exercise of the rights conferred on it by this clause 17, except for gross negligence and wilful default. The Security Agent shall not be obliged to make any enquiry as to the sufficiency of any sums received by it in respect of any book debts or other debt or claim so assigned to it or to make any claim or take any other action to collect in or enforce them. 18. APPLICATION OF MONEY RECEIVED BY THE SECURITY AGENT OR A RECEIVER 18.1 Application of Recoveries: Any money received under the powers conferred by this Debenture shall, subject to the discharge of any prior-ranking claims, be paid or applied in the order of priority set out in clause 8.9 of the Facility Agreement. 18.2 Suspense Accounts: The Security Agent may, in its absolute discretion on or at any time or times after demand and pending the payment to the Security Agent of the whole of the Secured Sums, place and keep to the credit of a separate or suspense account any money received, recovered or realised by the Security Agent by virtue of this Security for so long and in such manner as the Security Agent may determine without any intermediate obligation to apply it in or towards the discharge of any Secured Sum. 19.

SET-OFF (a) Each Beneficiary may, on or after the Enforcement Date, retain any money standing to the credit of any Charging Company with such Beneficiary in any currency upon any account or otherwise (in any country and whether or not in such Charging Company's name) as cover for any Secured Sums and/or at any time or times without notice to such Charging Company combine or consolidate all or any of such money with all or such part of the Secured Sums as such Beneficiary may select (whether presently payable or not) and such Beneficiary may purchase with any such money any other currency required to effect such combination. (b) Each Charging Company irrevocably authorises the Security Agent and each Beneficiary on or after the Enforcement Date in its name and at its expense to perform such acts and sign such documents as may be required to give effect to any set-off or transfer pursuant to clause 20(a), including the purchase with the money standing to the credit of any such account of such other currencies as may be necessary to effect such set-off or transfer. (c) The foregoing provisions of this clause shall be in addition to and without prejudice to such rights of set-off, combination, consolidation, lien and other rights whatsoever conferred on the Security Agent and the Beneficiaries by law. (d) If the Security Agent or a Beneficiary exercises its rights under this clause 20, it shall as soon as practicable notify the Primary Borrower. 21. SECURITY AGENT AS TRUSTEE, PERPETUITY PERIODS AND NO PARTNERSHIP 21.1 Security Agent: The Security Agent hereby declares itself to be a trustee of this Debenture (and any other security in its favour created pursuant to this Debenture) for the Beneficiaries.

Continuing Security: This Guarantee is a continuing security to the Security Agent and each Beneficiary and will continue in full force until no sum remains payable under the Finance Documents and the Beneficiaries have irrevocably received or recovered all sums payable under the Finance Documents irrespective of whatever dealings may occur on any account between the Security Agent or such Beneficiary and the Principal. 2. Opening of New Accounts: If this Guarantee ceases for any reason to be binding on the Guarantor as a continuing security in relation to the Principal, then each Beneficiary may break such accounts of the Guarantor and the Principal with such Beneficiary as such Beneficiary deems appropriate and open new accounts for the account holders affected. If that is done, no money credited to such new account at that time or later will have the effect of reducing the amount due to such Beneficiary on the original account. If that is not done, such Beneficiary will still be treated as if it had broken all such accounts at the time when such notice expired or this Guarantee ceased to be a continuing security and as if all payments made to such Beneficiary then or later had been credited to a new account with the same result. Such Beneficiary may also refuse payment (without notice to the Guarantor) of any cheque or order which, if paid or honoured, would reduce or further reduce the Guarantor's credit balances below the amount of its liability to such Beneficiary under this Guarantee at such time. 3. Payments: All payments falling to be made by a Guarantor under this Guarantee will be made to the Security Agent or the relevant Beneficiary without any set-off or counterclaim and free from any deduction or withholding for or on account of any taxes or other charges in the nature of taxes imposed by any competent authority. If any such deduction or withholding is required by law, the Guarantor will pay to the relevant Beneficiary any additional amount necessary to ensure that such Security Agent receives and retains the full amount of the relevant payment as if such deduction or withholding had not been made. 4. Suspense Account: The Security Agent and/or any Beneficiary may at any time (without prejudice to its other rights) place and keep for such time as the Security Agent or such Beneficiary may think prudent any money received, recovered or realised under or by virtue of this Guarantee on a separate or suspense account to the credit of either the Security Agent or such Beneficiary or the Guarantor (as the Security Agent or such Beneficiary thinks fit), without any intermediate obligation on its part to apply such money or any part of it in or towards discharge of the Secured Sums. 5. Additional to Other Security: This Guarantee is to be in addition to and is not to prejudice or be prejudiced by any other guarantee or security (including any other guarantee signed by the Guarantor) which the Security Agent or any Beneficiary may hold from or on account of the Principal either now or in the future. This Guarantee may be enforced at any time on or after the Enforcement Date without the Security Agent or any Beneficiary first making demand on the Principal or taking any steps or proceedings against the Principal or having recourse to any such other guarantee or security. 6. Restriction on each Guarantor: The Guarantor shall have no right to: (i) make any claim (whether by way of proof in liquidation or otherwise) against the Principal or any property of the Principal; or (ii) participate in any security held or money received by the Security Agent or any Beneficiary on account of the Secured Sums; or (iii) stand in the place of the Security Agent or any Beneficiary in respect of any such security or money; until in each case all Secured Sums have been repaid to the Security Agent and/or the Beneficiaries in full. However, if so directed by the Security Agent but not otherwise, the Guarantor shall prove in the Principal's liquidation for the whole or any part of the money due or owing to the Guarantor from the Principal in any manner whatever and the benefit of such proof and of all money received by the Guarantor in respect of it shall be held on trust for the Security Agent and applied in reduction of the Secured Sums. 7. Right to act without affecting the Guarantee: The Security Agent or any Beneficiary may at any time (without affecting its rights against the Guarantor under this Guarantee) grant, extend, increase, renew, vary, determine or refuse any credit or facility to the Principal, or take, hold, exchange, vary, release, abstain from perfecting or enforcing any guarantee or security for the Secured Sums, or compromise with or extend time or grant waivers, releases or any indulgence to the Principal or any co-surety, or make any arrangement, concession or settlement with any of them or do or omit or neglect to do anything whatever which, but for this provision, might exonerate or discharge the Guarantor's obligations under this Guarantee (except for a specific written release given by the Security Agent of such obligations). 8. Receipt of Payments: After this Guarantee becomes enforceable, no payment received by the Security Agent or any Beneficiary from any source (except the Principal) in respect of the Secured Sums will be treated (regardless of the manner in which the Security Agent or such Beneficiary may deal with it in its books or otherwise) as reducing the Guarantor's liability to the Security Agent or such Beneficiary under this Guarantee, so that until the Security Agent or such Beneficiary has received payment in full of all Secured Sums, it will be deemed, as between the Security Agent or such Beneficiary and the Guarantor and except for any payment by the Principal, to remain wholly unsatisfied. 9. Adjustments: If the state of account between the Security Agent or any Beneficiary and the Principal (by reference to which any Secured Sums are calculated for the purposes of this Guarantee) requires adjustment at any time because of any claim made against the Security Agent or such Beneficiary by an office-holder (within the meaning of Section 234 of the Insolvency Act 1986), then, notwithstanding any other provision of this Guarantee: (a) the Guarantor's liability to the Security Agent or such Beneficiary will be correspondingly adjusted, and (b) the Security Agent or such Beneficiary may treat any release or settlement made by it with the Guarantor before any such adjustment is required as being of no effect, and (c) the Security Agent or such Beneficiary may recover from the Guarantor such sum as will place the Security Agent or such Beneficiary in the same position as if such release or settlement had not been made. If any claim is made against the Security Agent or any Beneficiary under any insolvency law, the Security Agent or such Beneficiary may agree the claim or settle it on any terms it chooses without the necessity of asking for the Guarantor's agreement. If the Security Agent or such Beneficiary does agree or settle the claim, the Guarantor will be liable under this Guarantee as if a court order had been made containing the terms which the Security Agent or such Beneficiary have agreed. The Guarantor will be responsible for all costs and expenses which the Security Agent or such Beneficiary properly incurs in defending such a claim. 10. Retention: The Security Agent may keep the security held by it for the Guarantor's liability under this Guarantee in order to protect the Security Agent and the Beneficiaries against any possible claim under insolvency law for such period after all Secured Sums have been satisfied as the Security Agent reasonably considers to be necessary to avoid any risk under applicable insolvency law. If a claim is made against the Security Agent or any Beneficiary within that period, the Security Agent may keep the security until that claim has finally been dealt with. 11. Guaranteed Liabilities Continue to be Payable: The winding-up or dissolution of the Principal will not affect the Guarantor's liability under this Guarantee and any sum payable to the Security Agent or any Beneficiary at the date of the commencement of such winding-up or immediately prior to such dissolution (as the case may be) will be treated as continuing payable until actually paid in full. 12. Capacity of Principal: If any question arises as to the capacity of the Principal in relation to any dealing between the Principal and the Security Agent or any Beneficiary, or as to the capacity, authority or power of any officer, employee or agent of the Principal to bind it to any transaction with the Security Agent or any Beneficiary, or as to whether any of the Secured Sums are immediately due and payable, that question shall, as between the Security Agent or such Beneficiary and the Guarantor, be disregarded and the Guarantor will for the purposes of this Guarantee be and continue to be liable to the Security Agent or such Beneficiary in respect of any such dealing, transaction and/or Secured Sums as if the Guarantor were a principal debtor. 13. Currency Conversion: Any money received by the Security Agent or any Beneficiary under or by virtue of this Guarantee may be converted by the Security Agent or such Beneficiary at any time as it thinks fit (and notwithstanding any previous conversion) into any currency in which any part of the Secured Sums is due or owing to the Security Agent or such Beneficiary, in which event the net amount available to the Security Agent or such Beneficiary in such other currency (after allowing for all costs of conversion) shall be deemed to be the amount received by the Security Agent or such Beneficiary under or by virtue of this Guarantee. 14. Admission and Acknowledgement of Indebtedness: Any admission or acknowledgement in writing by the Principal or on its behalf of the amount of any Secured Sums or otherwise in relation to this Guarantee, or any judgment or award obtained by the Security Agent or any Beneficiary against the Principal, or any proof by the Security Agent or any Beneficiary in winding up which is admitted, or any statement of account furnished by the Security Agent or any Beneficiary the correctness of which is certified by any one of its directors, regional directors or managers, will be binding and conclusive on the Guarantor (except in the case of manifest error). 15. Financial Assistance: Notwithstanding any other provision of this Guarantee, this Guarantee shall not operate to guarantee any money or liability if and insofar as such money was borrowed or such liability was incurred directly or indirectly for the purpose of the acquisition by any person of shares in the Guarantor or its holding company or the reduction or discharge of any existing liability incurred for the purpose of such acquisition and if and for so long as it would not be lawful under Chapter VI, Part V, of the Companies Act 1985 for such money or liability to be guaranteed by this Guarantee. 16. Disability or Incapacity of any Principal: As a separate and independent stipulation and without prejudice to the provisions of clause 2 (Covenant to Pay), the Guarantor agrees that all sums of money which have become due hereunder and which may not be recoverable from it on the footing of a guarantee whether by reason of any legal limitation on or disability or incapacity of any Company or any other fact or circumstance, and whether known to any Beneficiary or not, shall as to an equivalent amount thereof nevertheless be recoverable from the Guarantor as sole or principal debtor or debtors in respect thereof and shall be paid on demand in writing made by the Security Trustee. 17. No Termination: Other than with the prior written consent of the Security Agent, the Guarantor shall not terminate its guarantee contained in this Debenture whilst any part of the Secured Sums remains outstanding.
