it based on the relevant service contact. 
 10. Delivery Metering and Payment Settlement 

10.1 By adhering to the international delivery metering principle of “metered by the deliverer under the supervision of the
receiver”, the parties shall work with each other to procure a satisfactory delivery metering. Metering at the loading point when the Shipper’s resources are loaded onto the pipelines shall be mainly performed by the Shipper under the
supervision of the Carrier; and on the contrary, metering at the unloading point of the pipelines shall be mainly performed by the Carrier under the supervision of the Shipper. For any unloading point at which the metering facilities are not
adequate to satisfy the delivery metering requirement, the party who is the owner of such delivery metering facilities shall upgrade such facilities to ensure accurate metering. 

  
 7 













 10.2 Metering data shall be subject to confirmation by the Shipper, the Carrier and the
related upstream or downstream operator. The authentication certificates of relevant instruments and calibration curves shall comply with applicable national standards, and shall be fully open to each other. The metering dispute reconciliation
mechanism and resolution method shall be set forth in the relevant delivery metering agreement among such three parties. 
 10.3 Oil and gas
transportation shall be managed by following the “delivery at the loading point and confirmation and settlement at the unloading point” model. The Carrier shall satisfy the Shipper’s requirements for physical inventory check at the
oil and gas depots (for natural gas, such check shall be done against account books) and shall follow the yearly check and yearly settlement practice. For crude oil and refined products, the actual pipeline transmission loss shall be calculated
based on actual loss, and any loss in excess the designed loss rate shall be borne by the Carrier, and any surplus oil (if any) shall be returned to the Shipper in proportion to the Shipper’s pipeline transportation volume. The surplus oil (if
any) shall be returned to the Shipper in a manner to be jointly considered and determined by the parties. The parties shall establish a joint inventory check coordination mechanism and develop an inventory check implementation plan through
consultations. 
 10.4 The parties have jointly determined that the designed loss rate for both crude oil pipeline transmission and refined
product pipeline transmission is £0.06%. In the event that the actual pipeline transmission loss rate in the course of operation deviates materially from the designed loss rate for three consecutive
years, the parties shall establish a mechanism to resolve such issue through consultations and jointly consider making an appropriate amendment to the designed pipeline transmission loss rate. Matters related to natural gas pipeline transmission
loss shall be governed by the Measures for Supervision and Examination of the Cost Base for Natural Gas Pipeline Transportation Pricing (the 2017 version, trial). Considering the fact that the loss cost is inclusive in the pipeline
transportation price, the transmission loss for natural gas arising from actual operations shall be borne by the Carrier. It is recommended that the transmission loss rate for natural gas to be adopted for those natural gas pipelines transferred to
the Carrier from the Shipper should be close to the actual loss rate incurred in actual operation during the three years immediately prior to handover of such pipelines to the Carrier. 

10.5 The quality of refined products entering the pipelines shall comply with the sequential transportation requirements and the line entry
quality standard agreed between the parties, and the refined products for offtake shall comply with the applicable national standards. The crude oil for offtake shall be substantially consistent with the quality of the crude oil entered the
pipeline. And natural gas transported through pipelines shall comply with the transmission and distribution quality requirements, and the parties shall work with each other to promote the measurement of natural gas transported through pipelines by
caloric value. 

  
 8 













 10.6 The pipeline transportation, gas storage, and LNG gasification services shall be priced
in accordance with the applicable pricing policies currently in effect, which consist of such three types as government-guiding prices, agreed prices and negotiated prices. The parties agree that, subject to applicable national natural gas pipeline
transportation pricing policies, the natural gas pipeline transportation fee shall be settled at the freight rate adopted in asset appraisal. For those pipelines crossing provinces appraised by the income approach shall be adjusted based on the
impact of changes in turnover volume (=Pipeline transportation volume × Average transportation distance) on the freight rate. 
 10.7
The parties agree that the settlement period for pipeline transportation fee shall be seven to ten days. The pipeline transportation fee for refined products and natural gas shall be paid by following the existing methods. The pipeline
transportation fee for crude oil shall be paid by using the agency collection and payment method. In the event that either party raises a dispute over any metering data, settlement bill or invoice, the part of the pipeline transportation fee that is
not subject to dispute shall be paid first, with the remaining amount of pipeline transportation fee to be paid after the dispute is eliminated. 

11. Overhaul and Maintenance of Production Equipment and Facilities 

11.1 Planned Overhaul and Maintenance  

11.1.1 Both parties shall schedule window periods for planned overhaul and maintenance in line with the overhaul and maintenance needs, and
strive to synchronize the overhaul and maintenance of upstream, midstream and downstream operations. In the course of actual operation, the overhaul and maintenance shall be arranged by following the principle of “annual negotiation, quarterly
confirmation and monthly implementation”. The parties shall work with each other to make the planned inspection and maintenance more seriously observed. In the event that the performance of any other contract is adversely affected by the
rescheduling of any planned overhaul and maintenance, such issues such be resolved in accordance with the applicable provisions in relevant contract(s). 

11.1.2 As for crude oil transmission pipelines, the overhaul and maintenance of transnational pipelines and storage tanks shall be
synchronized with that of domestic refineries. Before the Carrier and the applicable foreign party determine any plan to suspend the operation of any international pipeline, the Carrier shall have adequate discussions with the Shipper. The parties
shall jointly formulate the oil gas resource balancing plan for the overhaul and maintenance period of refineries designed to reduce the linepack to the lowest level immediately prior to the commencement of the overhaul and maintenance and increase
the pipeline transportation capacity to the highest level during the overhaul and maintenance period. 
 11.1.3 As for refined product
transmission pipelines, the overhaul and maintenance of pipelines and refineries shall be synchronized. The parties shall jointly formulate the pipeline refined product stock balancing plan for the overhaul and maintenance period of pipelines and
refineries so as to secure a steady supply of resources. 
 11.1.4 As for natural gas transmission pipelines, the overhaul and maintenance
of cross-border pipelines, domestic pipelines and domestic gas fields shall be synchronized. The window periods for centralized overhaul and maintenance of domestic pipelines and large gas fields shall be May and September each year. In anticipation
of such overhaul and maintenance, the parties shall formulate the resource balancing plan in advance, and strive to synchronize the overhaul of natural gas pipelines, gas storage depots and downstream users.
