(e)                                  borrow or raise money either unsecured or on the security of the Mortgaged Property (either in priority to the Mortgage or otherwise);

11

(j)                                     do anything else it may think fit for the realisation of the Mortgaged Property or incidental to the exercise of any of the rights conferred on the Collateral Agent under or by virtue of any document to which the Mortgagor is party; and

(k)                                  exercise all rights and remedies afforded to it under this Mortgage and applicable law.

7.2                               The Collateral Agent shall not be obliged to make any enquiry as to the nature or sufficiency of any payment received by it under this Mortgage or to make any claim or to take any action to collect any moneys assigned by this Mortgage or to enforce any rights or benefits assigned to the Collateral Agent by this Mortgage or to which the Collateral Agent may at any time be entitled hereunder.

7.3                               Upon any sale of the Mortgaged Property or any part thereof by the Collateral Agent, the purchaser shall not be bound to see or enquire whether the Collateral Agent’s power of sale has become exercisable in the manner provided in this Mortgage and the sale shall be deemed to be within the power of the Collateral Agent, and the receipt of the Collateral Agent for the purchase money shall effectively discharge the purchaser who shall not be concerned with the manner of application of the proceeds of sale or be in any way answerable therefor.

7.7                               The Collateral Agent shall not, by reason of the taking of possession of the whole or any part of the Mortgaged Property or any part thereof, be liable to account as mortgagee-in-possession or for anything except actual receipts or be liable for any loss upon realisation or for any default or omission for which a Collateral Agent-in-possession might be liable.

8.                                      APPOINTMENT OF A RECEIVER

8.1                               At any time after:

(a)                                  the occurrence of an Event of Default; or

(b)                                 a request has been made by the Mortgagor to the Collateral Agent for the appointment of a receiver over its assets or in respect of the Mortgagor,

then notwithstanding the terms of any other agreement between the Mortgagor and any person, the Collateral Agent may (unless precluded by law) appoint in writing any person or persons to be a receiver or receiver and manager of all or any part of the Mortgaged Property as the Collateral Agent may choose in its entire discretion.

8.2                               Where more than one receiver is appointed, the appointees shall have power to act jointly or separately unless the Collateral Agent shall specify to the contrary.

12

8.3                               The Collateral Agent may from time to time determine the remuneration of a receiver.

8.4                               The Collateral Agent may remove a receiver from all or any of the Mortgaged Property of which he is the receiver and after the receiver has vacated office or ceased to act in respect of any of the Mortgaged Property, appoint a further receiver over all or any of the Mortgaged Property in respect of which he shall have ceased to act.

8.5                               Such an appointment of a receiver shall not preclude:

(a)                                  the Collateral Agent from making any subsequent appointment of a receiver over all or any Mortgaged Property over which a receiver has not previously been appointed or has ceased to act; or

(b)                                 the appointment of an additional receiver to act while the first receiver continues to act.

8.6                               The receiver shall be the agent of the Mortgagor (which shall be solely liable for his acts, defaults and remuneration) unless and until the Mortgagor is placed into liquidation, after which time he shall act as principal. The receiver shall not at any time become the agent of the Collateral Agent.

9.                                      POWERS OF A RECEIVER

9.1                               Subject to the terms of the Intercreditor Agreement, in addition to those powers conferred by law, a receiver shall have and be entitled to exercise in relation to the Mortgagor all the powers set forth below:

(a)                                  to exercise all rights of the Collateral Agent under or pursuant to this Mortgage, including all voting and other rights attaching to the Mortgaged Property;

(b)                                 to make any arrangement or compromise with others as he shall think fit;

(c)                                  to appoint managers, officers and agents for the above purposes at such remuneration as the receiver may determine;

(d)                                 to redeem any prior encumbrance and 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 Mortgagor and the money so paid shall be deemed an expense properly incurred by the receiver;

(e)                                  to pay the proper administrative charges in respect of time spent by its agents and employees in dealing with matters raised by the receiver or relating to the receivership of the Mortgagor; and

(f)                                    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 Mortgaged Property or the value thereof.

10.                               FURTHER ASSURANCES

10.1                         The Mortgagor shall at its own expense promptly do all such acts or execute all such documents (including assignments, transfers, mortgages, charges, notices and instructions) as the Collateral Agent may reasonably specify and in such form as the Collateral Agent may reasonably require in order to:

13

(a)                                  perfect or protect the security created or intended to be created under or evidenced by this Mortgage (which may include the execution of a charge, assignment or other security over all or any of the assets which are, or are intended to be, the subject of this Mortgage) or for the exercise of any rights, powers and remedies of the Collateral Agent provided by or pursuant to this Mortgage, the Indenture Documents or by law; or

(b)                                 following an Event of Default, subject to the Intercreditor Agreement, facilitate the realisation of the assets which are, or are intended to be, the subject of this Mortgage.

10.2                         Without limiting the other provisions of this Mortgage, the Mortgagor shall at its own expense take all such action as is available to it (including making all filings and registrations) as may be necessary for the purpose of the creation, perfection, protection or maintenance of any security conferred or intended to be conferred on the Collateral Agent by or pursuant to this Mortgage.

11.                               INDEMNITIES

11.1                         The Mortgagor will indemnify and save harmless the Collateral Agent, any receiver and each agent or attorney appointed under or pursuant to this Mortgage from and against any and all reasonable expenses, claims, liabilities, losses, taxes, costs, duties, fees and charges suffered, incurred or made by the Collateral Agent or such agent or attorney other than as a result of the gross negligence or wilful default of the Mortgagee:

(a)                                  in the exercise or purported exercise of any rights, powers or discretions vested in them pursuant to this Mortgage;

(b)                                 in the preservation or enforcement of the Collateral Agent’s rights under this Mortgage or the priority thereof;

(c)                                  on the release of any part of the Mortgaged Property from the security created by this Mortgage; or

(d)                                 arising out of any breach by the Mortgagor of any term of this Mortgage,

and the Collateral Agent or such receiver, agent or attorney may retain and pay all sums in respect of the same out of money received under the powers conferred by this Mortgage.  All amounts suffered, incurred or paid by the Collateral Agent or such receiver, agent or attorney or any of them shall be recoverable on a full indemnity basis provided that nothing in this Clause 11.1 shall require the Mortgagor to indemnify and save harmless the Collateral Agent from and against any expenses, claims, liabilities, losses, taxes, costs, duties, fees and charges suffered, incurred or made by the Collateral Agent as a result of the Collateral Agent’s dishonesty or wilful default.

11.2                         If, under any applicable law or regulation, and whether pursuant to a judgment being made or registered against the Mortgagor or the bankruptcy or liquidation of the Mortgagor or for any other reason any payment under or in connection with this Mortgage is made or fails to be satisfied in a currency (the “Payment Currency”) other than the currency in which such payment is due under or in connection with this Mortgage (the “Contractual Currency”), then to the extent that the amount of such payment actually received by the Collateral Agent when converted into the Contractual Currency at the rate of exchange, falls short of the amount due under or in connection with this Mortgage, the Mortgagor, as a separate and independent obligation, shall indemnify and hold harmless the Collateral Agent against the amount of such shortfall.  For the purposes of this Clause 11.2, “rate of exchange” means the rate at which the Collateral Agent is able on or about the date of such payment to purchase the Contractual Currency with the Payment Currency and shall take into account any premium and other costs of exchange with respect thereto.

14

12.                               POWER OF ATTORNEY

12.1                         The Mortgagor, by way of security and in order more fully to secure the performance of its obligations hereunder, hereby irrevocably appoints the Collateral Agent and the persons deriving title under it (including, but without any limitation, any receiver) jointly and also severally (with full power of substitution and delegation) to be its attorney-in-fact:

(a)                                  to execute and complete in favour of the Collateral Agent or its nominees or of any purchaser any documents which the Collateral Agent may from time to time require for perfecting the Collateral Agent’s title to, for vesting any of the assets and property hereby mortgaged, or charged in the Collateral Agent or its nominees or in any purchaser or for any of the purposes contemplated in Clause 7.1 hereof;

(b)                                 after the occurrence of an Event of Default, to give effectual discharges for payments, to take and institute on non-payment (if the Collateral Agent in its sole discretion so decides) all steps and proceedings in the name of the Mortgagor or of the Collateral Agent for the recovery of such moneys, property and assets hereby mortgaged or charged;

(c)                                  after the declaration by the Collateral Agent of an Event of Default, to agree accounts and make allowances and give time or other indulgence to any surety or other person liable;

(d)                                 so as to enable the Collateral Agent to carry out in the name of the Mortgagor any obligation imposed on the Mortgagor by this Mortgage (including the execution and delivery of any deeds, charges, assignments or other security and any transfers of the Mortgaged Property and the exercise of all the Mortgagor’s rights and discretions in relation to the Mortgaged Property);

(e)                                  so as to enable the Collateral Agent and any receiver or other person to exercise, or delegate the exercise of, any of the rights, powers and authorities conferred on them by or pursuant to this Mortgage or by law (including, after the occurrence of an Event of Default, the exercise of any right of a legal and beneficial owner of the Mortgaged Property), and

(f)                                    generally for it and in its name and on its behalf and as its act and deed or otherwise execute, seal and deliver and otherwise perfect and do any such legal assignments and other assurances, charges, authorities and documents over the moneys, property and assets hereby charged, and all such deeds, instruments, acts and things which may be required for the full exercise of all or any of the powers conferred or which may be deemed proper on or in connection with any of the purposes aforesaid,

in each case, subject to the terms, conditions and provisions of the Intercreditor Agreement.

12.2                         Notwithstanding any other provision of Clause 12.1, the power of attorney created by Clause 12.1 shall not be exercisable by or on behalf of the Collateral Agent as the case may be until an Event of Default has occurred.

12.3                         The power hereby conferred shall be a general power of attorney and the Mortgagor hereby ratifies and confirms and agrees to ratify and confirm any instrument, act or thing which any attorney appointed pursuant hereto may execute or do.  In relation to the power referred to herein, the exercise by the Collateral Agent of such power shall be conclusive evidence of its right to exercise the same.

15

13.                               EXPENSES

13.1                         The Mortgagor shall pay to the Collateral Agent on demand all reasonable costs, fees and expenses (including, but not limited to, properly incurred legal fees and expenses) and taxes thereon incurred by the Collateral Agent or for which the Collateral Agent may become liable in connection with:

(a)                                  the negotiation, preparation and execution of this Mortgage;

(b)                                 the preserving or enforcing of, or attempting to preserve or enforce, any of its rights under this Mortgage or the priority hereof;

(d)                                 any consent or waiver required from the Collateral Agent in relation to this Mortgage

and in the case referred to in Clauses 13.1(c) and 13.1(d), regardless of whether the same is actually implemented, completed or granted, as the case may be.

13.2                         The Mortgagor shall pay promptly all registration, stamp, documentary and other like duties and taxes to which this Mortgage may be subject or give rise and shall indemnify the Collateral Agent on demand against any and all liabilities with respect to or resulting from any delay or omission on the part of the Mortgagor to pay any such duties or taxes.

14.                               RELEASE

14.1                         Subject to Clause 14.2, when all the Secured Obligations have been paid in full in cash or the Security Interest created by this Mortgage is automatically released pursuant to Section 11.04 of the Indenture, the Collateral Agent shall (at the request and cost of the Mortgagor) execute such documents and do all such reasonable acts as may be necessary to release the Mortgaged Property from the security constituted by this Mortgage.  Such release shall not prejudice the rights of the Collateral Agent under Clause 11.

14.2                         If the Collateral Agent considers in good faith that any amount received in payment or purported payment of the Secured Obligations (whether received from or paid by the Company, any Other Guarantor or any other relevant person) is capable of being avoided or reduced by virtue of any insolvency or other similar laws:

(a)                                  the liability of the Mortgagor under this Mortgage and the security constituted by this Mortgage shall continue and such amount shall not be considered to have been irrevocably paid; and

(b)                                 the Collateral Agent may keep any security held by it in respect of the Mortgagor’s liability under the Indenture Documents in order to protect the Secured Parties against any possible claim under insolvency law for up to six years after all Secured Obligations have been satisfied.  If a claim is made against a Secured Party within that period, the Collateral Agent may keep the security until that claim has finally been dealt with.

15.                               NOTICES

Any notice or other communication given or made under or in connection with the matters contemplated by this Mortgage shall be provided in accordance with Section 12.03 of the Indenture (with any notice to the Mortgagor prior to the Transaction Time to be delivered care of the Borrower).

16

16.                               ASSIGNMENTS

16.1                         This Mortgage shall be binding upon and shall enure to the benefit of the Mortgagor, the Collateral Agent and each of their respective successors and (subject to clauses 16.2 and 16.3) assigns and references in this Mortgage to any of them shall be construed accordingly.

16.2                         The Mortgagor may not assign or transfer all or any part of its rights and/or obligations under this Mortgage.

17.2                         Nothing in this Mortgage shall constitute or be deemed to constitute a partnership between any of the Secured Parties and the Collateral Agent.

18.                               SET-OFF

18.1                         The Mortgagor authorises the Collateral Agent (but the Collateral Agent shall not be obliged to exercise such right), after the occurrence of an Event of Default to set off against the Secured Obligations any amount or other obligation (contingent or otherwise) owing by the Collateral Agent to the Mortgagor.

19.                               SUBSEQUENT SECURITY INTERESTS

19.1                         If the Collateral Agent at any time receives or is deemed to have received notice of any subsequent Security Interest affecting all or any part of the Mortgaged Property or any assignment or transfer of the Mortgaged Property which is prohibited by the terms of this Mortgage, all payments thereafter by or on behalf of the Mortgagor to the Collateral Agent shall be treated as having been credited to a new account of the Mortgagor and not as having been applied in reduction of the Secured Obligations as at the time when the Collateral Agent received such notice.

20.                               MISCELLANEOUS

20.1                         The Collateral Agent, at any time and from time to time, may delegate by power of attorney or in any other manner to any person or persons all or any of the powers, authorities and discretions which are for the time being exercisable by the Collateral Agent under this Mortgage in relation to the Mortgaged Property or any part thereof.  Any such delegation may be made upon such terms and be subject to such regulations as the Collateral Agent may think fit.  The Collateral Agent shall not be in any way liable or responsible to the Mortgagor for any loss or damage arising from any act, default, omission or misconduct on the part of any such delegate provided the Collateral Agent has acted reasonably in selecting such delegate.

20.2                         If any of the clauses, conditions, covenants or restrictions (the “Provision”) of this Mortgage or any deed or document emanating from it shall be found to be void but would be valid if some part thereof were deleted or modified, then the Provision shall apply with such deletion or modification as may be necessary to make it valid and effective.

17

20.3                         This Mortgage (together with any documents referred to herein) constitutes the whole agreement between the Parties relating to its subject matter and no variations hereof shall be effective unless made in writing and signed by each of the Parties.

20.4                         Each document, instrument, statement, report, notice or other communication delivered in connection with this Mortgage shall be in English or where not in English shall be accompanied by a certified English translation which translation shall with respect to all documents of a contractual nature and all certificates and notices to be delivered hereunder be the governing version and upon which in all cases the Collateral Agent and the Secured Parties shall be entitled to rely.

20.5                         This Mortgage may be executed in counterparts each of which when executed and delivered shall constitute an original but all such counterparts together shall constitute one and the same instrument.

20.6                         The parties intend that this Mortgage take effect as a deed notwithstanding the fact that the Collateral Agent may only execute it under hand.

20.7                         Whenever reference is made in this Mortgage to any action by, consent, designation, specification, requirement or approval of, notice, request or other communication from, or other direction given or action to be undertaken or to be (or not to be) suffered or omitted by the Collateral Agent or to any election, decision, opinion, acceptance, use of judgment, expression of satisfaction or other exercise of discretion, rights or remedies to be made (or not to be made) by the Collateral Agent, it is understood that in all cases the Collateral Agent shall be acting, giving, withholding, suffering, omitting, taking or otherwise undertaking and exercising the same (or shall not be undertaking and exercising the same) as directed in accordance with the Indenture.  This provision is intended solely for the benefit of the Collateral Agent and its successors and permitted assigns and is not intended to and will not entitle the other parties hereto to any defense, claim or counterclaim, or confer any rights or benefits on any party hereto.

21.                               LAW AND JURISDICTION

21.1                         This Mortgage shall be governed by and construed in accordance with the laws of the Cayman Islands and the Parties hereby irrevocably submit to the non-exclusive jurisdiction of the courts of the Cayman Islands, provided that nothing in this clause shall affect the right of the Collateral Agent to serve process in any manner permitted by law or limit the right of the Collateral Agent to take proceedings with respect to this Mortgage against the Mortgagor in any jurisdiction nor shall the taking of proceedings with respect to this Mortgage in any jurisdiction preclude the Collateral Agent from taking proceedings with respect to this Mortgage in any other jurisdiction, whether concurrently or not.

22.                               INTERCREDITOR AGREEMENT

22.1                         The Security Interests created by this Mortgage on the property described herein are subordinate to the Security Interests on such property created by any similar instrument already granted to any First Priority Secured Party, in such property, in accordance with the provisions of the Intercreditor Agreement.  Notwithstanding anything to the contrary, the exercise of any right or remedy by the Collateral Agent hereunder is subject to the provisions of the Intercreditor Agreement.  In the event of any conflict between the terms of the Intercreditor Agreement and this Mortgage, the terms of the Intercreditor Agreement shall govern.
