D. REASONS FOR AND BENEFITS OF THE TRANSACTIONS

Since 2009, the governments of the United States and European Union have imposed anti-dumping measures and countervailing duties on imported Chinese-made oil pipes, accusing the relevant imports as selling below fair market value. Such policies restricted the Company’s abilities to sell the Oil Pipe Products directly in the overseas markets and it imposed adverse effects on the business of the Company. However, in September 2010, the entering into of the Shareholders Agreement symbolized strategic partnership between the Company and Vallourec Group. Making use of the Distributor’s global supply network, the Company maintained its sales of the Oil Pipe Products outside the PRC through the Sales Agreement and the Extension Agreement despite the restrictions in certain key markets overseas. In the past few years under the Sales Agreement and the Extension Agreement, the Company’s Oil Pipe Products had been sold to the global oil field enterprises, such as France’s Total, Kuwait National Petroleum Company, etc.

In addition, currently the Company is able to sell its manufactured Premium Products in form of Premium Products or premium products threaded with premium connections. When sold in latter form, the Company has to engage VAM CZ (a subsidiary of Vallourec) to process the Premium Products into the premium products threaded with premium connections branded with Vallourec pursuant to the Extended Processing Agreement,the Extended Trademark License Agreementand the Extended Technical and Commercial Support Agreement before selling the processed products in Chinaas the Company does not own the relevant patentedtechnology. However, in reality, customers are more willing to accept that Vallourec sells its own brandedpremium productsthreaded with premium connections for ensuring the quality. Therefore the Company believes that the appointment of Distributors to sell the Premium Productsnot only savesthe processing fees, royalty fee for trademark license and the technical support fee, but also is more conducive to market development.

Strategically, the entering into of the New SalesAgreement indicates the willingness and intention of continuingthe existing strategic partnership between the Company and Vallourec group. The New Sales Agreement will help the Groupcontinue to realize its vision of global development strategies and enlarge its customer base.

The Groupshould be able to expand its product offerings in the PRC of new products equipped with more advanced technologies and through the New Sales Agreement, maintain its sales outside of the PRC despite the current restrictions in certain key markets overseas and is conducive to market development for the Premium Products. Such cooperation would accordingly continue to enhance the Group’s competitiveness in line with the long term interest of the Groupand the Board believes that the terms of the New Sales Agreement are fair and reasonable and in the interests of the Shareholders and the Group as a whole.
