Chapter 3 Contracted Gas Volume and Gas Supply Plan

1. Volume of Gas Supply

According to the current gas production and transfer situations of the Supplier and the demand of the User, through negotiation, both
parties agree to the following quantities of gas supply during the term of the Agreement:

(1) Annual Gas
Supply: 1,250  1,800 ×104m3

The User shall use gas and settle gas price with the Supplier based on the Type of Gas Usage and Structure (percentage) of Gas Usage
contemplated under this Agreement as follows:

A. Gas for use in production: 1,250  1,800×104m3, or 100% of Annual Gas Supply;

B. CNG gas: × 104m3, or  % of Annual Gas Supply; and

C. City gas (including domestic gas for staff) : ×
104m3, or  % of
Annual Gas Supply.

Among them,

(1) Gas for domestic or other use:× 104m3, or  % of Annual Gas Supply (ending
20 yearmonthday, the total number of households is
 in relation to the use of domestic gas by the Users residents or staff)

(2) Industry gas for re-supply:× 104m3, or  % of Annual Gas Supply;

D. Gas for other use: × 104m3, or  % of Annual Gas Supply.

The Supplier may suspend at short notice the supply of the abovementioned types of gas (with the exception of gas for use in glass
furnaces) under special circumstances, such as when acting in concert with planned maintenance or in execution of the gas marketing contingency plan. In such event, upon the completion of maintenance or the execution of the gas marketing contingency
plan, the Supplier shall resume gas supply in a timely manner. Regarding the supply of gas for use in glass furnaces, the Supplier shall supply gas according to the average gas flow per hour calculated based on the Daily Gas Supply stipulated in
this Agreement. In the event of pipeline explosion or other emergencies that dictate suspension of gas supply, or upon receiving request for suspension due to other circumstances with reasonable notice, the Supplier shall suspend the gas supply in a
cooperative manner. Glass furnaces factories must set up the relevant security and insulation facilities and contingency mechanisms.

For users that use more than one type of gas, the gas price shall be billed and settled in every settlement period according to percentage of different types of gas set out in the Structure of Gas Supply
above. If the actual structure of gas usage is different, the User shall provide materials in relation to the actual structure of gas usage, which, after being verified, can be used as basis to adjust the settlement.

In the event that the User uses up the Annual Gas Supply before the term of the Agreement expires, the Supplier may, as the case may be,
suspend the supply of gas to the User until the parties reach a gas supply Agreement for the following year.

(2) Verification
of Type of Gas and Structure of Gas Usage

Gas prices shall be calculated separately according to the Type of Gas. If such
separate calculations are not in place yet, the User shall provide the details of Type of Gas and Structure of Gas Usage, of which the User reserves the right to conduct verification whenever necessary.

Should the Supplier requests for verification at the time when the Agreement is entered into
or during the process of its execution, the User shall provide all the relevant materials that can feasibly prove the actual Structure of Gas Usage, e.g. any gas fee voucher, production statement, financial statement or sales statement. In the event
that the User refuses to provide materials or provides untrue materials, gas prices will be billed and settled based on the estimated Structure of Gas Usage and such settlement will not be adjusted until the User provides true materials.

The Supplier may reduce or terminate gas supply if the User refuses to make payment or provide relevant materials in accordance with this
Agreement, and the User shall be liable for all the consequences, including but not limited to shortage of gas funds caused to the Supplier and its own losses due to the suspension of gas supply.

Monthly Gas Supply refers to the volume of gas apportioned to each month from the Annual Gas Supply and
Daily Gas Supply refers to the average amount of the Monthly Gas Supply apportioned to each day or the average gas daily supply volume as arranged by the monthly gas supply plan, excluding the days when maintenance is scheduled or cooperation for
maintenance is required and the amount of gas used on such days.

In principal, Monthly Gas Supply shall be proportioned
according to the practical situation of gas production and transportation, so that the difference between the monthly highest gas usage and the monthly lowest gas usage (calculated based on Daily Gas Supply) shall not exceed 10% of the Monthly Gas
Supply of the previous month. Any request for supply beyond the abovementioned volume can only be met according to the monthly sales plan prepared by the Supplier within the term of the Agreement.

It is both parties responsibility to secure the use of gas for domestic and commercial purposes, for CNG and in airports and to
maintain social stability. According to the general principle of gas supply in the country Guarantee some, limit the others, industrial users shall reduce or suspend gas usage from November to March the next year to avoid the peak time
for gas consumption in the spring and winter. Suppler will give 3 days notice to the User if it is necessary to reduce or suspend gas supply. In such event the User must reduce or suspend gas usage accordingly in due time.

(4) Peak management facilities and peak management responsibilities

In line with the Suppliers actual production and transportation capacity and its responsibility to supply gas, the Supplier can
only supply gas according to the average hourly gas flow calculated based on the Daily Gas Supply, because the Supplier is incapable of and is not responsible for managing gas peak for the User. Under the current circumstances, the Supplier will
endeavor to satisfy the Users demand for gas, not its needs to meet the peak management requirements, and the Supplier shall not be liable for any influences or consequences in this regard.

In accordance with relevant state regulations, city/county gas companies must properly resolve issues in relation to gas peak management
to make sure that stability of gas supply and the safety of the gas transfer pipeline network. Therefore, city/county gas companies must set up and improve gas reserve and management facilities and make sure that such facilities are put to effective
operation.

The Supplier will supply gas according to the hourly gas flow calculated based on the Daily Gas Supply in a
proportionate manner and the User shall be solely responsible for any influences or consequences thereto.

2. Monthly Gas Supply Plan

(1) The Supplier shall arrange its gas production according to the volume agreed upon under this Agreement and the User
shall use gas according to this Agreement, in both cases, in a proportionate manner. Subject to the Annual Gas Supply and disclaimers stipulated in this Agreement, the Supplier in principal shall arrange supply according to the Monthly Gas Supply
stipulated above.

(2) Adjustment to the Monthly Gas Supply: Subject to the Annual Contracted Volume and according to the
actual situation of production and usage, the User may request by giving 5 days written notice to adjust the Monthly Gas Supply for the next month. (The adjustment shall not exceed 10% of the Monthly Gas Supply stipulated in this Agreement. For the
exceeding part, the Supplier can only try to make arrangements according to the gas supply plan based on the actual status of gas sales. ) Upon receiving the written request for adjustment, the Supplier may decide whether to adjust supply according
to the actual production of the month and so notify the User.

Chapter 4 Prices

In line with the provisions of gas prices by state and local governments, the gas prices (after tax) are as follows:

adjusted accordingly effective from the price adjustment date stipulated in the regulations on gas prices by state and local governments.

Chapter 5 Billing and Payment

To ensure that the User stably and safely
uses gas and in order to ensure that the Supplier will receive the gas payments, this Agreement adopts the following methods of billing and settlement for the prepayment of gas supply.

(1) Payment period for gas supply: After the Agreement is signed and goes into effect, when the User first uses the gas supply in 2011,
he should remit the initial prepayment amount to the Suppliers account before April 1, 2011. For future payments, the User should remit the next periods prepayment amount to the Suppliers account before the last day of the
prior settlement period. Should the Supplier not receive the next periods gas supply prepayment, the Supplier will stop the provision of gas once the User finishes the using the gas supply provided from previous prepayments. If both parties
have not signed a gas supply Agreement for 2012 by December 31, 2011 yet both parties still continue to supply and use gas, then both parties will temporarily carry out billing and settlement according to the provisions in the Agreement for
2011 until a supply Agreement for the next year is signed.

(2) Every time the User prepays one settlement period, which is 45
days payments of gas supply, the prepayment amount shall be RMB6.55 million.

(3) The Supplier will base the settlement
of gas payments on the gas intersection measurement value and starting ten days before next month and on a monthly basis, shall issue a gas invoice to the User.

(4) Three days before a settlement period ends the Supplier shall either via written or telephone communication notify the User to prepay the following periods gas payment. The User should prepay
the following periods gas payment before the end of the prior settlement period (the balances for a settlement period should be added to the remaining balances in originally prepaid payments as the payment of a whole settlement period). If at
the end of the prior settlement period the Supplier has not received the Users prepayment for the following period, the Supplier will not notify the User and will discontinue the supply of gas once the User completely uses up its last fully
prepaid gas supply. All consequences from this will be borne solely by the User.

(5) Gas payment method: Before the end of
each settlement period the User should use the method of bank transfer to prepay the following periods gas payments to the Suppliers bank account. The User may not change the Suppliers bank and bank account number agreed upon in
this Agreement with formal written notification from the Supplier.

(6) The User should pay the gas payments to the Supplier
according to the payment methods set out in this Agreement. If the User uses bankers acceptance to pay the gas payments, it must receive approval from the Supplier and it will be responsible for the discounted interest rates, administration
fees etc. arising from the bankers acceptance.

Chapter 6 Maintenance and Coordination

The User and Supplier should coordinate with each other regarding the plans for production and transportation of gas, the use of
facilities or temporary maintenance. Should any changes or fluctuations in the supply and use of gas occur during the plans or temporary maintenance, the best effort should be made to control the situation within the appropriate boundaries.

1. Synchronous planned maintenance

According to the arrangements made by both parties in the arrangement table on gas production, purification, transportation, and planned maintenance of gas facilities, during the period of the
Suppliers planned maintenance, the User should, according to the plan, accommodate the planned maintenance. During the entire year, the number of the days that the User will produce (or use gas) will be
 calendar days and the number of days of maintenance or coordinated maintenance will be 
calendar days. Specific maintenance times are arranged based on the 20  synchronous maintenance plan arrangement table detailed below:

__(month) __(date), 20 to __(month)
 (date), 2009, an daily average of  x 104m3to be supplied during this period;

__(month) __(date), 20 to __(month)
 (date), 2009, an daily average of  x 104m3to be supplied during this period;

__(month) __(date), 20 to __(month)
