 Schedule of Facilities for “Line for Treasury Products” shall be replaced by:

 SCHEDULE OF FACILITIES 
 Line for Treasury Products 
  

					
	Line for Treasury Products:	  	  
 The risk-weighted limit of the products to be
traded, including but not limited to, plain vanilla foreign exchange forward/foreign exchange swap trades (“Plain Vanilla Forward/Swap Trades”) and other derivative trades (“Other Derivative Trades”, together with Plain Vanilla
Forward/Swap Trades, “Trade” or “Trades”) must not exceed the limit as set out below at any time. The Bank may allocate the limit within the products below or other products as agreed to be traded between the Bank and the
Customer from time to time.

		
		  	Revised as below:
			
		  	Facility Limit (expressed in risk-weighted limit and represented in below currency or its equivalent in any other currency including RMB, calculated at the then prevailing
spot exchange rate)	  	Maximum Tenor (unless prior arrangement between the parties)
			
		  	Total Limit of Line for Treasury Products not exceeding USD2,500,000.-	  	12 months
		
		  	Products that can be traded under the Line for Treasury Products
		
		  	Foreign Exchange Trades (including Plain Vanilla Forward/Swap Trades)
		
		  	The aggregate amount of utilisation under the Facility will be calculated by the Bank on a risk-weighted basis using its standard risk-weighting algorithms. These
will use different weightings for different products. The aggregate amount of utilisation under the Facility shall be as calculated by the Bank, such calculation to be conclusive.

 Purpose and 
 Supporting Documents: 
  

			
		
		  	The Customer undertakes that it shall enter into Plain Vanilla Forward/Swap Trades or Other Derivative Trades contemplated under this Facility Letter with the Bank only to cover
trade related exchange exposure incurred in the normal course of business and/or other exchange exposure to the extent permitted by law (the “Purpose”), and that it shall be solely responsible for providing any documents evidencing the
Purpose and any other additional information and/or supporting documents as requested by the Bank from time to time (the “Supporting Documents”) to the Bank to the latter’s satisfaction to facilitate the entry into and settlement of
any Trade. For avoidance of doubt, the Bank may require any such Supporting Documents from the Customer from time to time, whether before or after the entry into or the settlement of the relevant Trade. The Bank shall have the right (but not the
obligation) to rely on the Supporting Documents provided by you without further verification.
		
		  	In the case of your breach of any obligation, undertaking, representation or covenant hereunder or in any other document relating to the Facility or the Trades (including, but
not limited to, your failure to or delay in providing any Supporting Documents to the Bank’s satisfaction), the Bank shall have the sole discretion to close out any or all of the outstanding transactions under the Facility and the Trades and
demand settlement of the balance due. Without prejudice and in addition to any general lien, right of set-off or other right which the Bank may have on any account whatsoever, the Customer agrees that the Bank may at any time and without prior
notice apply any monies held in any currency to the credit of any account or any other account in the name of the Customer against any settlement amount that the Customer owes to the Bank. If as a result of such settlement, there are payables to
you, the Bank shall have the right to retain for its own account such payables without the need to making such payments to you.
		
	Worst Case Scenario Of Plain Vanilla Forward/Swap Trade:	  	
		
		  	In relation to plain vanilla forward/swap transactions, the worst case scenario refers to as follows. If on each settlement date for forward/swap transactions the spot exchange
rate (represented by numbers of converted currency per one base currency) were to increase to an infinite number (in the case the Customer sells base currency and buys converted currency) or to decrease to a near-zero number (in the case the
Customer sells converted currency and buys base currency), the Customer would still have to settle the transactions on the original agreed settlement rate, in which case the Customer would pay all of the notional amounts in the currency originally
agreed to pay and receive the amount in the currency originally agreed to receive, and the current value represented by the amount of currency received by the Customer on such settlement date would be minimal.

	Dealing Procedures:	  	Application
		
		  	In relation to a Plain Vanilla Forward/Swap Trade (including where you request for rollover or early settlement in respect of any Plain Vanilla Forward/Swap Trade by entering

provided that any communication made by email, telephone or other method acceptable to the Bank shall contain information necessary for the Bank to proceed with the relevant Plain Vanilla Forward/Swap Trade, or shall be made in such other specific
form as required by the Bank from time to time. In relation to forward/swap transactions, if you request for rollover in respect of any original transactions by entering into reversal transactions and new transactions with the Bank, the netting
gains or losses generated after offsetting the reversal transactions against the original transactions must be settled between you and the Bank on the maturity date of the original transactions.

assets/liabilities are real and authentic, and there does not exist any unsettled derivative transaction exposure linked to these underlying assets/liabilities;

the Customer is capable to sustain the worst case scenario as described in the term sheet or other documents (if applicable) of the Trades;
		
	Payment:	  	Both you and the Bank agree that if payment under any Trade remains to be payable by both you and the Bank on the same day, the Bank shall not be required to make the payment due
from the Bank to you on that day until the time when the Bank has received confirmation that the Bank has received the payment due from you on that day in full at the Bank’s designated account.
		
		  	The Bank shall not be liable to you for any interest, loss, expense or any other cost associated with any delayed payment by the Bank as a result of acting in accordance with the
foregoing procedures provided that the Bank has acted promptly and in good faith.

		  	 (2)     the Bank shall be entitled to assume without further enquiry that any Indemnified Instrument
purporting to be that of any person authorized by you, is that of such person and genuine and is binding upon you;

		
		  	 (3)     the Bank is hereby irrevocably and unconditionally authorised to accept and to act on any
Indemnified Instruments which the Bank in its sole discretion believes emanates from you and shall not be liable to you for acting in good faith in reliance thereon;

		
		  	 (4)     the Bank shall not be liable for, and you hereby waive to the fullest extent permitted by

		  	 (5)     you hereby undertake to keep the Bank indemnified at all times against, and to keep the Bank

		  	The Bank reserves the right to refuse to accept or act upon any Indemnified Instrument or any part thereof without incurring any responsibility for loss, liability or expense
arising out of such refusal, if, at the Bank’s sole discretion:
		
		  	 (1)     such Indemnified Instrument is or proves to be in conflict with any applicable laws or

	Acknowledgement:	  	You hereby acknowledge and undertake that, in connection with this Facility Letter and the Trades:
		
		  	 (1)     you are not relying and will not rely upon any advice (whether written or oral) of the other
party to this Facility Letter or the Trades, other than the representations expressly set forth in this Facility Letter or the Trades;

		
		  	 (2)     you have made and will make your own decisions regarding the execution of this Facility
Letter and the Trades based upon your own judgment and/or advice from your own professional advisers as you have deemed necessary to consult with;

		
		  	 (3)     you fully understand and accept the terms, conditions and risks of this Facility Letter and

any other master agreement executed by and between the Bank and the Customer.


  
 15 










			
		  	The Bank may waive temporarily the requirement to sign any master agreement with the Customer for the transactions under the facilities. In the absence of any ISDA Master
Agreement or FX Master Agreement or any other master agreement executed by and between the Bank and the Customer, any Trade (together with all other documents referring to the 2002 ISDA Master Agreement (the “ISDA Form”) entered into
between the Bank and the Customer) shall be governed by the ISDA Form as if the Bank and the Customer had executed an agreement in such form on the Trade Date as of the first Trade between the Bank and the Customer (but without any schedule except
for the election of the laws of the PRC as the governing law, the submission of any dispute in connection with the ISDA Form to the Shanghai Sub-Commission of China International Economic and Trade Arbitration Committee by arbitration for final
settlement, USD as the Termination Currency and any other elections set out in the relevant trade documentation). The foregoing provisions in this paragraph shall apply, if the parties agree to use the ISDA Form to govern the Trades even though we
have executed the FX Master Agreement.
		
		  	The waiver in the foregoing paragraph will not prejudice the Bank’s right to require the Customer to sign a master agreement at the time the Bank deems fit.
		
		  	The definitions and provisions contained in the 1998 FX and Currency Option Definitions or the 2006 ISDA Definitions (as the case may be) shall be incorporated into the
Application and/or other Trade-related documents governing such transaction.
		
	Risk Disclosure Statement:	  	  
 The Bank wishes to draw your attention to the financial risks
and the market risks associated with the Trades offered by the Bank. Under certain market conditions, you may sustain gains as well as losses. In particular, the return on the Trades is dependent on the exchange rate or interest rate movements of
the relevant currencies prevalent at the relevant date or during the relevant period (as the case may be). Specific market movements of such exchange rates or interest rates cannot be predicted accurately and the profit and loss in a Trade related
to exchange rate or interest rate will be affected by fluctuations of such rates.

		
		  	You must be prepared to accept these risks and all other risks (which can be substantial) and the Bank will not be responsible for any losses whatsoever incurred by you in
respect of any Trade. You should therefore carefully consider whether such trading is suitable for you in light of your financial condition, experience and objectives.


  
 16 










			
		 	You should also ensure that you (a) fully understand the nature of any Trade and the contractual relationship into which you are entering and the nature and extent of your
exposure to risk of loss; and (b) evaluate the tax and accounting implications, the potential financial benefits and risks of any Trade.
		
		 	The Bank recommends that you obtain independent legal advice before placing any Trade.
		
		 	You should act in reliance on your own judgment and evaluation and upon such independent professional advice as you may deem appropriate.
