Notwithstanding the foregoing, the Lessor or the property management company designated by the Lessor has the right to cut off water, power or air conditioning of the Object leased by the Lessee without any responsibility, provided that the Lessee shall be notified of such intention three days in advance. The expenses incurred by the Lessor or the property management company designated by the Lessor due to cut-off and re-connecting of water, power or air conditioning shall be borne by the Lessee, which may be recovered by the Lessor from the Lessee or deducted from the deposit paid by the Lessee in accordance with Article VIII of these Detailed Rules.

(2)                       Exercise of rights

Instead of actually entering the Object, the Lessor sending to the Lessee a written notice of taking back the Object in the form prescribed by the Lease will be deemed as fully exercising the right. The Lessor will be deemed to have taken back the Object and the Lessee be deemed to have been expelled from the Object seven days after the Lessor delivers such a written notice (that is, the evacuation period for the Lessee). During the evacuation period, if the Lessee fails to restore the Object to the state described in the confirmation document signed upon acceptance of the Object, the Lessor shall be entitled to freely dispose any item left by the Lessee in the Object without taking any responsibility to the Lessee, and all expenses resulting therefrom shall be borne by the Lessee.

When the Lessee returns the Object, if there remains some items, fixtures or fittings in the Object, the Lessee hereby declares a waiver of its ownership of such properties, and consents to free disposal by the Lessor of such properties (including but not limited to abandonment, selling off or other means), with all proceeds thereof to the account of the Lessor (if any) and all expenses involved to be borne by the Lessee (if any). The Lessor shall assume no responsibility to the Lessee or any other person for any loss or damage caused by such disposal or any other treatment method.

(3)                       Acceptance of rent and property management fees

The acceptance of rent by the Lessor and the acceptance of property management fees by the property management company designated by the Lessor shall not be deemed as an automatic waiver of their right to prosecute the Lessee for default, incompliance with or nonperformance of terms and conditions it shall comply with and perform.

24

(4)                       Acts of contractors, employees, agents and visitors

For the purpose of the Lease, any act of any employee, visitor, contractor, representative or agent of the Lessee or user of the Object shall be deemed as act of the Lessee.

(5)                       Payment order

The failure of the Lessee to pay the rent and property management fee for the Object in the time and manner prescribed by the Lease shall constitute delay in payment. In such case, the Lessor or the property management company designated by the Lessor may apply to the people’s court for a payment order in accordance with the Civil Procedure Law of the People’s Republic of China, with all related expenses incurred therefrom to be borne by the Lessee.

(6)                       Overdue fines

Without prejudice to any other right and remedial measure available to the Lessor upon default, if the rent, property management fees, any other expenses or a part thereof hereunder haven’t been paid in the way and time prescribed in Articles 4 to 6 of the Lease and Part I of the Detailed Rules, the Lessee shall pay overdue fines equivalent to 0.1% of the aggregate amount due but unpaid each day from the due date to the actual payment date (both the due date and the actual payment date are included).

(7)                       Commitment

Unless otherwise specified herein, in no event (except force majeure) may the Lessee terminate the Lease in advance during the Tenancy Term, if the Lease is early terminated or becomes unfulfillable due to reasons of the Lessee, the Lessor is not liable to return to the Lessee the paid deposit. The Lessor may not terminate the Lease for no cause, or otherwise, it shall be liable for breach of contract.

VIII. Deposit

(1)                       Deposit

Simultaneously with the execution of the Lease, the Lessee shall pay to the Lessor the deposit prescribed in Article 5 of the Lease, so as to ensure the compliance with the terms and conditions the Lessee shall comply with and perform.

The deposit shall be preserved free of interest by the Lessor on behalf of the Lessee.

(2)                       Withholding and deduction of deposit

In the instance the Lessee violates any term or condition of the Lease, the Lessor shall be entitled to urge actual performance and deduct from the deposit: the expenses due but unpaid by the Lessee, the charges required to be assumed by the Lessee according to the Lease or provisions of laws and regulations, or losses suffered by the Lessor because of default, incompliance or nonperformance of the Lessee.

(3)                       Complement of deposit

Pursuant to the Lease, in case the rent and property management fees increase in the Tenancy Term, or the deposit becomes insufficient as deducted by the Lessor due to default of the Lessee, the Lessee shall, within ten working days after the receipt of a written notice from

25

the Lessor or the property management company designated by the Lessor, make up the deposit.

Complementing the deposit is a prerequisite for further performance of the Lease. If the Lessee fails to do so, the Lessor shall be entitled to exercise all remedies and rights available.

(4)                       Return of deposit

Subject to the above provisions, the deposit shall be returned in Renminbi free of interest to the Lessee at the latest of thirty days after the Object vacated is handed over to the Lessor upon expiration of the Lease, or thirty days after the resolution of claims arising from default, incompliance with or nonperformance of the terms and conditions of the Lease and from incompliance and nonperformance of regulations that the Lessee shall comply with and perform, or thirty days after the settlement of the Lessee’s accounts with the telecommunications company and the power corporation, except the part that the Lessor has the right to deduct, withhold or offset pursuant to the Lease.

(5)                       Change of Lessor

If the Lessor changes during the Tenancy Term, all rights and obligations in respect of the deposit paid by the Lessee or the deposit remaining after the Lessor exercises its deduction right according to the Lease shall be succeeded by the new lessor. In this case, the Lessor shall make sure the Lessee’s rights will not be adversely affected by such change of lessor.

When the formulation and update of any rules cause a significant impact on the Lessee’s rights, the Lessee shall be entitled to raise an objection and retains the right to recover its losses from the Lessor.

(2)                       Conflict

Such rules are merely supplementary to these terms and conditions of the Lease, which will not invalidate the latter. In the case of controversy between such rules and these terms and conditions hereof, the terms and conditions of the Lease shall prevail.

The marginal notes, headings and indexes are for guidance only, and shall not constitute an integral part of the Lease, which shall not be given consideration to or affect or restrict the interpretation or clarification of any provision hereof.

26

(2)                       No waiver by tolerance

The Lessor’s tolerance, forgiveness or excuse of one-off or repeated nonperformance, violation, incompliance or non-execution of responsibility hereunder by the Lessee doesn’t imply a waiver of rights regarding continuous or further nonperformance, violation, incompliance or non-execution by the Lessee, nor eliminate or affect the Lessor’s rights or compensation available hereunder in respect of such continuous or further nonperformance of violation.

Unless the Lessor waives its rights in written statement, no act or omission of the Lessor implies waiver of rights or infers as waiver.

Any approval given by the Lessor applies only to certain issues specifically approved, which shall not operate as simultaneous waiver of other rights available to the Lessor nor exempt the Lessee from further applying to the Lessor for any other specific written approval.

(3)                       Service of notice
