	5.	Obligations of TRINA 

  

	5.1	TRINA will deliver the Products on the basis of confirmed orders placed by IBC and TRINA, provided, however, that the orders have been made according to the regulations of this
Agreement. 

  

	5.2	TRINA will deliver the Products according to the specifications in Annex 3 and in accordance to all other written technical agreements between both parties.

  

	5.3	TRINA will deliver the Products on a very high quality-level. TRINA will at every time do his best efforts to improve quality and reliability of the Products. Especially TRINA will
work on a high relative power-output of the solar-modules at lower insolation compared to the nominal power at nominal insolation to ensure a high energy-production of these modules per year. 

  

	5.4	TRINA will deliver the Products certified according to international rules, esp. IEC 61215:2005, IEC 60904-1, IEC 60904-3 and TÜV-safety-class II in the actual and valid
version. If the certifications are still in the testing procedure, Trina provides IBC a confirmation from the testing institute that Trina has applied for the both tests. When IEC 61730-1 becomes mandatory in Europe IBC will only accept modules
according to this standard. 

  

	5.5	TRINA will acknowledge any official test-result from a first-class international research-institute such as Fraunhofer ISE in Freiburg or TÜV-Rheinland in Cologne (or any other
reputable institute) concerning the Products. If in any case discrepancy is found between TRINA’s specification and institute test-result, TRINA ensures to take action to supply Products according to the specification and to replace the
originated damage. 

  

	5.6	TRINA will support IBC in customer and warranty services for the Products in accordance with the warranty-terms in Annex 2. TRINA will bear all costs for warranty-services
according to TRINA’s obligation as set forth in Annex 2 once both parties reach mutual agreement. 

  

	5.7	TRINA will receive IBC’s representatives from time to time and grant such representative any assistance required in assessing the Products, the quality and the manufacturing of
the Products. 

  

	5.8	TRINA will observe at all times any and all applicable rules and regulations regarding fair competition and the avoidance of corruption and other illicit business practices.
Furthermore, TRINA shall inform IBC about any unfair competition practices of third parties with regard to the Products as well as possible infringements of patents, trade-marks and other intellectual property rights of IBC without undue delay and
in writing. 

  

	5.9	TRINA will inform IBC without undue delay in writing should any third party acquire direct or indirect control of TRINA. 

  

	5.10	void 

  

 4 

	5.11	TRINA will keep clear sales-structures. This means, that in Europe TRINA will establish only distributors (wholesalers) in Europe, but will not offer or deliver the Products to
end-users or installers (exception for customers with a demand of above 3MWp/Year). If IBC asks for customer-protection or project-protection TRINA will give such protection and will not offer or deliver directly with the exception, that TRINA can
clearly prove, that TRINA had continuous business with such customers before our request. 

  

	5.12	TRINA shall advise and support IBC in connection with the establishment and operation of its business as well as with regard to the servicing of the Products and to use all
reasonable endeavours to meet all orders for the Products forwarded to TRINA by IBC in accordance with the terms of this Agreement. 

  

	5.13	TRINA shall provide such information and support as may reasonably be requested by IBC to enable it properly and efficiently to discharge its duties under this Agreement.

  

	6.	Prices and Payments 

  

	6.1	The price for each Product will be calculated on the basis of the formulae set forth in Annex 5. All prices quoted in the price list are net prices to which VAT, sales or
other taxes and levies shall be added as required under applicable statutes, rules and regulations. All taxes and levies that are by applicable statutes, rules and regulations required to be paid by TRINA shall be paid by TRINA. All other taxes or
levies shall be paid by IBC. 

  

	6.2	Prices and payment terms shall be fixed bindingly for each calendar quarter at least 12 weeks before the beginning of this calendar quarter. A changed price for the following
calendar quarter becomes valid when both parties agree on that new Annex 5 in writing. 

  

	 6.3
	 Prices and payment terms shall be fair and reasonable according to the market-situation. Both parties have the right to
request a price adaptation for the following quarter. In case both parties can not agree on new pricing and payment terms for the following calendar quarter, both parties will supply information on pricing and market to explain their position. Both
parties will always engage to find a mutual agreement on pricing. In case both parties can not find an agreement on new pricing for a calendar quarter even after such discussion, the old price for a calendar quarter stays valid for the next calendar
quarter. In case this automatic extension of price-validity has taken place for 2 calendar quarters following each other, both parties have the right to reduce shipments. In general both parties agree in the goal to reduce pricing by at least [****]
† per year.

TRINA shall have the right to cancel the respective order by IBC and dispose otherwise of such shipment at its sole discretion. Before TRINA disposes any shipment to another customer, TRINA will inform IBC and give him a time of 14 days to fulfil
the delayed payment-request. 

  

	6.6	IBC shall be free to determine its own prices and conditions in reselling the Products. We will work on mutual agreement in case of any conflict. 

  

	6.7	The delivered goods remain property of Trina until all his rights to IBC that are based on the delivery according to Art.6 of this agreement have been fulfilled. Should the
delivered goods be connected with other goods or be processed by IBC, then the goods are partially property of Trina to the fraction that corresponds to the relation of the delivered goods to the other goods used by IBC on time of connection.
Mortgage, transfer of ownerships as security on a debt or other degrees that restrict the right of property are not admissible. Intervention costs are chargeable to IBC. 

  

	7.	Withdrawal of Products and Specification Changes
