The Escrow Parties agree that neither the Escrow Agent nor any member of the Citi Organisation is responsible or liable for any action taken to comply with sanctions or government requirements. Upon the occurrence of any Force Majeure Event, to the extent allowed by applicable law, the Escrow Agent shall use its reasonable efforts to minimise the effect of the Force Majeure Event on the Escrow Parties.

The Escrow Agent may act in reliance upon any instrument or signature believed by it to be genuine and may assume that any person purporting to give receipt or advice or make any statement or execute any document in connection with the provisions hereof has been duly authorised to do so;

(g) the Escrow Parties acknowledge that:

(i) adverse or conflicting claims, demands or Instructions being made, threatened or given in connection with the Escrow Property; or

4.2 Cash Held as Banker.  The Custodian, or where applicable a sub-custodian, will hold Cash as banker, as a debt due to the Client, and not as trustee or fiduciary.  As a result, Cash will not be held in accordance with Client Money Rules or similar rules in any jurisdiction and, in the event of the Custodian’s insolvency (or analogous event), the Client may not be entitled to share in any distribution under the Client Money Distribution and Transfer Rules.

4.3 Cash Held by a Sub-Custodian.

4.3.2 Any cash held directly by a sub-custodian on behalf of the Client will be owed by that sub-custodian directly to the Client, and will not be subject to UK or other client money rules or held by the Custodian as banker for the Client. Such cash will be subject to the relevant laws or regulatory rules applicable to the sub-custodian, including the laws and rules of the jurisdiction in which the sub-custodian is located. Notwithstanding the previous sentence, or any other terms of this Agreement, the Custodian agrees that it shall have the same liability to the Client for the cash held with a sub-custodian as if such cash was held for the Client by the Custodian as banker in the relevant market.

4.3.3 Unless otherwise specified in this Agreement, the terms of this Agreement in relation to Custody Cash Accounts shall apply to a cash account held by the Client with a sub-custodian.

The Custodian intends that Securities will be held in such manner that they should not become available to the insolvency administrator or creditors of the Custodian.

4.6.2 The Custodian may hold Securities with an Agent only where the Agent has been selected and appointed as a sub-custodian. The Custodian shall hold Securities only in an account at the sub-custodian that holds exclusively assets held by the Custodian for the Client and that has been so identified on the books and records of the sub-custodian. The Custodian shall require the sub-custodian to identify on its records in a manner so that it is readily apparent that the Securities: (i) do not belong to the Custodian and are held by the Custodian for and belong to the Client; (ii) do not belong to the sub-custodian or other clients of the sub-custodian; and (iii) are segregated on the books and records of the sub-custodian from the sub-custodian’s and its other clients’ assets. The Custodian shall require each sub-custodian to agree that Securities will not be subject to any right, charge, security interest, lien or claim of any kind in favour of the sub-custodian. Any Securities held with any sub-custodian will be subject only to instructions of the Custodian and any Securities held in a Clearance System for the account of a sub-custodian will be subject only to the instruction of the sub-custodian.

4.6.3 The Custodian shall and shall require any sub-custodian to hold Securities in a Clearance System only in an account that holds assets exclusively belonging to the Client and that has been so identified on the books and records of the Clearance System or that is identified at the Clearance System in the name of a nominee of the Custodian or sub-custodian used exclusively to hold Securities for the Client. In certain markets, the Custodian or its sub-custodian may open an account at a Clearance System in the name of the Client or its customer, as required by the rules of the Clearance System.

4.6.4 The Custodian shall and shall require any sub-custodian to record book-entry Securities or uncertificated Securities settled outside a Clearance System on the books and records of the applicable transfer agent or registrar (or the issuer if none) in a way that identifies that the Securities are being held by the Custodian or its sub-custodian as custodian for the clients and are not assets belonging to the Custodian or the sub-custodian, if applicable.

4.6.5 The Custodian shall and shall require any sub-custodian to hold certificated Securities in registered or bearer form in its vault segregated from certificates held for itself and/or any other clients. If the registered certificates are not registered in the Custodian’s or its sub-custodian’s name (or its nominee name) the Custodian will not be responsible for asset services as provided in Section 8 of the Custody Terms.

4.6.6 The Custodian may hold Securities in the name of a nominee of the Custodian or its sub-custodian or a nominee of the Clearance System as may be required by that Clearance System.

4.6.7 The Custodian shall require that any actions with respect to Securities held for the Client under this Agreement in a Clearance System or in the name of the Custodian, a sub-custodian or any nominee on the books and records of any transfer agent or registrar will be subject only to the instructions of the Custodian or its sub-custodian, if applicable.

5.1.1 The Client shall ensure that it has sufficient Securities or sufficient immediately available Cash in the required currency credited with the Custodian as necessary to effect any Instruction or other delivery or payment required under this Agreement.

5.1.2 The Custodian may, but is not obliged to, credit Cash to the Custody Cash Account before a corresponding and final receipt in cleared funds. The Client acknowledges that the Custodian may at any time before final receipt, or if a Clearance System at any time reverses an applicable credit to the Custodian, reverse all or any part of a credit of Cash to the Client and make an appropriate entry to its records including restatement of the Custody Cash Account and reversing any interest paid.

5.1.3 The Custodian will credit Securities to the Custody Account upon receipt of the Securities by final settlement determined in accordance with the practices of the relevant market.  Finalsettlement depends on the market confirmation of settlement to the Custodian and may include real time movement with finality, real time movement without finality, or confirmation of settlement but with movement of securities at end of the day. If any Clearance System reverses any credit of Securities (or the Custodian is otherwise obliged to return Securities as a result of a settlement reversed in accordance with market requirements), the Client acknowledges that the Custodian may reverse all or any part of the credit of the Securities to the Custody Account and make an appropriate entry to its records including restatement of the Custody Account.  In the event of any reversal of Securities, the Custodian may reverse any credit of Cash provided to the Client with respect to the Securities, such as distributions or the proceeds of any transaction.

5.1.4 The Custodian shall provide the Client with prompt notice of a reversal of Cash or Securities.

5.1.5 Where notice of a reversal of Cash or Securities has been given and there is insufficient Cash or Securities to satisfy the reversal, the Client shall, as applicable, promptly repay in the applicable currency the amount required to satisfy the deficit in the Custody Cash Account and/or return any Securities to the Custody Account.

5.1.6 If the Custodian has received Instructions (or is authorised under this Agreement to make any delivery or payment without an Instruction) that would result in the delivery of a Security or payment of Cash in any currency exceeding credits to the Client for that Security or Cash, the Custodian may in its discretion, subject to acting consistently with the standard of care in this Agreement: (i) make partial deliveries or payments consistent with market practice; (ii) fulfil a subsequently received Instruction to the extent of then available Securities or Cash held for the Client; or (iii) suspend or delay acting on any Instruction until it receives the required Securities or Cash.  The Custodian shall notify the Client if the Custodian does not act on any Instruction because the Client has insufficient Securities or Cash.

5.1.7 Notwithstanding termination of the Agreement, these Custody Terms or any Instruction, the Custodian may retain such amount of Securities or Cash as is necessary to close out or complete

- 41 -

any: (i) Instruction received by the Custodian in accordance with the terms of the Agreement and not revoked; or (ii) other transaction which the Custodian was required or expressly permitted to effect in accordance with the terms of the Agreement (including the Custody Terms) or pursuant to Applicable Law, in each case prior to the date of termination of the Agreement but which has not been settled, closed out or completed as of the date of termination of the Agreement.

5.1.8 The Client will not enforce any payment obligation of the Custodian at or against another branch or affiliate of the Custodian. The Custodian is obliged to pay Cash only in the currency in which the applicable payment obligation is denominated and only in the country in which such Cash is used in connection with Securities received, held or delivered or other services under this Agreement are provided in that country, regardless of whether that currency’s transferability, convertibility or availability has been affected by any law, regulation, decree rule or other governmental or regulatory action. The Client agrees that it may not require the Custodian or any member of the Citi Organisation to substitute a currency for any other currency.

5.2 Instructions

The Custodian shall not act upon any Custody Instruction unless it is signed by the Relevant Authorised Representative(s) of each of the Escrow Parties, save that, in the case of a Custody Instruction to be delivered pursuant to Clause 4.1(c) of the Agreement, the Custodian may act upon such Custody Instruction if it is signed by the Relevant Authorised Representative(s) of the Client only.

8.4 Taxes.

8.4.1 The Client shall provide the Custodian, from time to time and in a timely manner, with information and proof (copies or originals) as to the Client’s tax status, residence, beneficial ownership or other information as the Custodian reasonably requests in order for the Custodian or any Agent to achieve compliance with the requirements of governmental or regulatory authorities and applicable law. Information and proof may include executed certificates, representations and warranties, or other

- 44 -

documentation the Custodian deems necessary or proper to fulfil the requirements of applicable tax authorities.  The Client shall notify the Custodian in writing of any change that affects the Client’s tax status pursuant to any applicable law or regulation, legal, governmental or regulatory authority, or agreement entered into between any two or more governmental authorities (law, regulation and authority, as used in this sentence, may be domestic or foreign), and the Client shall provide the notice within thirty (30) days of that change or any lesser period as stipulated under any applicable law or regulation.

8.4.2 Taxes are the responsibility of the Client and the Client agrees that Taxes shall be paid by the Client. The Custodian will deduct or withhold for or on account of Taxes from any payment to the Client if required by any applicable law including, but not limited to: (i) statute or regulation; (ii) a requirement of any legal, governmental or regulatory authority; or (iii) an agreement entered into by the Custodian and any governmental authority or between any two or more governmental authorities (applicable law as used in this sentence may be domestic or foreign).  The Client acknowledges that the Custodian may debit any amount available in any balance held for the Client and apply such Cash in satisfaction of Taxes.

8.4.3 In the event the Client requests that the Custodian provide tax relief services and the Custodian agrees to provide such services, the Custodian will apply for appropriate tax relief (either by way of reduced tax rates at the time of an income payment or retrospective tax reclaims in certain markets as agreed from time to time); provided that the Client provides to the Custodian such documentation and information relating to it or its underlying beneficial owner customers as is necessary to secure such tax relief. However, in no event will the Custodian be responsible, or liable, for any Taxes resulting from the inability to secure tax relief, or for the failure of any Client or beneficial owner to obtain the benefit of credits, on the basis of foreign taxes withheld, against any income tax liability.

8.4.4 For the avoidance of doubt, if Taxes are deducted or withheld (by any person or entity) from any payment which is received by the Custodian for the Client in relation to Securities held for the Client by the Custodian, the Custodian shall only be required to pay or credit to the Client the amount actually received and retained by the Custodian in respect of that payment.

11.6.2 Country Risk.  The Client agrees that it shall bear all risks and expenses associated with investing in Securities or holding Cash denominated in any currency.  The Client acknowledges that the Custodian will not be liable for country specific risks of loss or value or other restrictions resulting from country risk, including the risk of investing and holding Securities and Cash in a particular country or market such as, but not limited to, risks arising from: (i) any Force Majeure Event (as defined in the Agreement); (ii) investment, repatriation or exchange control restriction or nationalization, expropriation or other actions by any governmental authority; (iii) devaluation or revaluation of any currency; (iv) changes in applicable law; and (v) a country’s financial infrastructure and practices including market rules and conditions.

11.6.3 Conformity with Market Practices.  Notwithstanding the Client’s Instruction to deliver Securities against payment or to pay for Securities against delivery, the Client authorises the Custodian to make or accept payment for or delivery of Securities at such time and in such form and manner as complies with relevant local law and practice or with the customs prevailing in the relevant market.

- 47 -

11.6.4 Prevention of Performance. The Custodian shall not be responsible for any loss or damage, or failure to comply or delay in complying with any duty or obligation, under or pursuant to this Agreement arising as a direct or indirect result of any Force Majeure Event or any event where, in the opinion of the Custodian, acting reasonably, performance of any duty or obligation under or pursuant to this Agreement would or may be illegal or would result in the Custodian being in breach of any law, rule, regulation, or any decree, order, award, decision or judgment of any court, or practice, request, direction, notice, announcement or similar action (whether or not having the force of law but with which the Custodian would normally comply) of any relevant government, government agency, regulatory authority, stock exchange or self-regulatory organisation to which the Custodian is subject.  In such case its obligations will be suspended for so long as the Force Majeure Event or other event as aforesaid continues (and, in the case of the Custodian, neither it nor any member of the Citi Organisation shall become liable). The Client agrees that neither the Custodian nor any member of the Citi Organisation is responsible or liable for any action taken to comply with sanctions or government requirements.  Upon the occurrence of any Force Majeure Event, to the extent allowed by applicable law, the Custodian shall inform the Client and shall use its reasonable efforts to minimise the effect of the Force Majeure Event on the Client. The Custodian confirms that it and each Agent maintains and regularly tests disaster recovery plans and contingency back-up services designed to mitigate the effects of any Force Majeure Event and which meet the standards to be expected of an internationally regulated financial institution.

11.6.5 Client’s Reporting Obligations.  The Client agrees that it shall be solely responsible for all filings, tax returns and reports relating to Securities or Cash as may be required by any relevant authority, whether governmental or otherwise.

11.6.6 Capacity of Custodian.  The Client acknowledges that the Custodian is not acting under this Agreement as an investment manager, broker, or investment, legal or tax adviser to the Client.  The Custodian’s duty is solely to act as a custodian in accordance with these Custody Terms.

11.6.7 No Implied Duties.  The Client agrees that the Custodian is responsible for the performance of only those duties set forth in these Custody Terms, including the performance of any Instruction. The Client acknowledges that the Custodian will have no implied duties or obligations except as cannot be excluded by applicable law.

11.6.8 Sole Obligations of the Custodian.  The Client understands and agrees that: (i) the obligations and duties of the Custodian will be performed only by the Custodian and are not obligations or duties of any other member of the Citi Organisation (including any branch or office of the Custodian); and (ii) the rights of the Client with respect to the Custodian extend only to such Custodian and, except as provided by law, do not extend to any other member of the Citi Organisation.

11.6.9 No Liability for Third Parties. The Custodian is not responsible for the acts, omissions, defaults or insolvency of any third party including, but not limited to, any broker, counterparty or issuer of Securities.

12. NOT AGENT FOR CLIENT’S CUSTOMERS; CLIENT’S DIRECT LIABILITY.

The Client agrees that it will not be relieved of its obligations as principal as the Client under these Custody Terms where (or if) the Client discloses that it has entered into these Custody Terms as agent, custodian or other representative of another person.  Notwithstanding any requirement that accounts, documentation or agreements, or transactions be effected in the name of any customer of the Client or for any other beneficial owner acting directly or indirectly though the Client, the Client agrees that it shall be responsible as principal for all obligations to the Custodian with regard to such beneficial owner accounts, agreements, or transactions.

- 48 -

13. CONFLICTS OF INTEREST

13.1 Compliance with Requirements.  The Client acknowledges that the Custodian has arrangements in place to manage conflicts of interest (the “Conflicts Policy”). If the Custodian deems that the arrangements are not sufficient to reasonably prevent risks of damage to the Client, the Custodian shall clearly disclose the general nature and/or the sources of the conflict of interest to the Client before undertaking the relevant business with or for the Client.

13.2 Information.  The Client acknowledges that members of the Citi Organisation including Citibank, N.A. may separately provide services, including advisory, credit, and other financial services, to the Client or to other persons other than as custodian under this Agreement. In connection with those services the Custodian or its Agent may be prohibited by applicable law or by its Conflicts Policy or other policies from disclosing information of which it becomes aware or from accessing any information in relation to those services. As a result, the Client agrees that neither the Custodian nor any member of the Citi Organisation is required or expected to disclose to the Client any non-public information it obtains in the course of providing services other than as Custodian. Also, the Client acknowledges that except as provided in these Custody Terms, the Custodian has no obligation to disclose to the Client any public or non-confidential information it obtains from any source about which relates to any issuer, counterparty or other person, regardless of whether such information relates to any Security held or to be received for the Client.

13.3 Services to Client or the Custodian.  The Custodian may share any fees, profits and non-monetary benefits with any member of the Citi Organisation or other third parties (including a person acting on their behalf) or receive fees, profits and non-monetary benefits from them in respect of the services provided pursuant to this Agreement. The Custodian shall provide details of the nature and amount of any such fees, profits or non-monetary benefits on the Client’s written request.

14. FEES AND EXPENSES

The Client agrees to pay all Fees to the Custodian in accordance with Clause 10 of the Agreement. In addition, the Client shall pay, on the written request of the Custodian, all Depository Services Fees and Dividend Fees incurred or to be incurred by the Custodian in relation to the Securities. The Client agrees that the Custodian may debit the Custody Cash Account to pay any such Fees, charges and obligations. The Client agrees that all Fees and amounts paid to the Custodian shall be payable without deduction for Taxes, which are the responsibility of the Client and if any deduction for Taxes is required by law in respect of any such payment, the Client shall pay to the Custodian such additional amounts as will ensure the Custodian receives the amount it was due had no such deduction been made.

15. TERMINATION

15.1 Termination. These Custody Terms shall terminate in accordance with Clause 16.1 of the Agreement and the Custodian shall be discharged from all duties and liabilities hereunder.

15.2 Closure of Custody Account. The Custodian may close any Custody Account or Cash Account as the Custodian reasonably considers necessary for the Custodian or any other member of the Citi Organisation to comply with applicable law in regard to Taxes or other requirements including, but not limited to: (i) statute or regulation; (ii) legal, governmental or regulatory authority; or (iii) agreement entered into by the Custodian and any governmental authority or between any two or more governmental authorities (applicable law as used in this sentence may be domestic or foreign) as provided in this Agreement, provided that the Custodian shall give the Client such notice of such closure as is reasonably practicable and such notice shall constitute a Resignation Notice for the purposes of Clause 9.2 of the Agreement.

- 49 -

15.3 Resignation. Delivery of a notice of replacement or resignation of the Escrow Agent in accordance with Clause 9.1 or 9.2 of the Agreement, as appropriate, shall be deemed a notice terminating these Custody Terms with effect from the Resignation Date. Where Clause 9.1 or 9.2 of the Agreement applies, the Custodian shall comply with Clause 9.3 of the Agreement, as applicable to the Custody Account and Custody Cash Account.

15.4 Effect on Securities and Cash. Where any of Clauses 16.1(b) to 16.1(e) of the Agreement applies, the Custodian shall comply with Clauses 16.4, 16.5 and 16.6 of the Agreement, as applicable to the Custody Account and Custody Cash Account. The Client shall be liable for standard fees for Securities or Cash retained in safekeeping after termination of these Custody Terms.

15.5 Surviving Terms.  The parties agree that the rights and obligations contained in Sections 5.1.2, 5.1.3, 5.1.8, 6. 7.4, 8.4.2, 10 and 11 of these Custody Terms shall survive the termination of this Agreement.

16. CITI ORGANISATION INVOLVEMENT

The Client agrees and understands that any member of the Citi Organisation can engage as principal or otherwise in any transaction effected by the Client or by any person for its account and benefit, or by or on behalf of any counterparty or issuer.  When instructed to effect any transactions (particularly foreign exchange transactions), the Custodian is entitled to effect any transaction by or with itself or any member of the Citi Organisation and to pay or keep any fee, commissions or compensation as specified in the Client’s Instruction or, if no specification is provided, any charges, fees, commissions or similar payments generally in effect from time to time with regard to such or similar transactions.

17. MISCELLANEOUS

17.1 Further Information.  The Client agrees to execute further documents and provide to the Custodian all documents and other information reasonably requested by the Custodian in relation to its performance of services under the Custody Terms and its duties and obligations under the Custody Terms in order to assist the Custodian with the requirements of a court, regulator or other legal authority in relation to an applicable market, including providing the identities of the beneficial owners of any Securities or Cash and providing any powers of attorney or similar authority or terms and conditions in relation to any cash account opened with any sub-custodian in the name of the Client or any of its customers to enable or facilitate the opening or operation of such cash account on behalf of the Client for the purpose of the Custody Terms.

17.2 Incorporation of Provisions. The provisions of Clause 7 (Escrow Agent), 10 (Fees and Expenses), 11 (Notices), 12 (General) and 13 (Governing Law and Arbitration) to 15 (Waiver of Sovereign Immunity), and Clause 17 (Language) of the Agreement will have effect as if set out in these Custody Terms mutatis mutandis.
