[For Immediate Release] Xinhua Far East applauds progress of CAO’s restructuring and upgrades the issuer rating of CAO to investment grade HONG KONG, December 7, 2005 – Xinhua Far East China Ratings (Xinhua Far East) today upgrades the issuer credit rating of China Aviation Oil (Singapore) Corp Ltd (“CAO” or “the Company”, SGX ChinaAviOil) from C to BBB+. The rating is also on review for further possible upgrade. The rating action is prompted by the considerable progress made in the restructuring of CAO which will not only lead to an injection of USD 130 million new capital to CAO but also catalyze improvement in risk management and corporate governance by the two strategic investors, respectively linked to BP and Temasek Holding. In Xinhua Far East’s opinion, this latest development will give rise to a viable restructuring plan that will revitalize CAO’s credit profile which was abruptly devastated by the Company’s massive derivative trading loss last December. As such, it will be able to restore an investment grade credit risk profile quickly. Furthermore, Xinhua Far East believes that the demonstrated support by CAOHC and strategic investment by BP will reinforce CAO’s dominant market position in fast growing jet fuel sector in China, and thereby increase the likelihood for a further rating upgrade in next 18 months. According to CAO’s latest announcement, it has signed a conditional investment agreement with its holding company, China Aviation Oil Holding Company (“CAOHC”), and BP Investment Asia Ltd (“BP”), and a conditional subscription agreement with Aranda Investments Pte Ltd (“Aranda”), an indirect wholly-owned subsidiary of Temasek Holdings (Private) Ltd. According to the investment agreements, the three companies will inject US$130 million into CAO, of which CAOHC will invest US$75.77 million and will have a majority stake of 51% post-restructuring, BP will invest US$44 million for a post-restructuring stake of 20% and Aranda will invest US$10.23 million for a 4.65% post-restructuring stake. During the past year, CAO’s restructuring process has remained on track. Its Scheme of Arrangement (“the Scheme”) was overwhelmingly approved by its creditors in June 2005 and amid the buoyant growth in China’s jet fuel market, the Company has effectively resumed its jet fuel procurement operations through its wholly-owned subsidiary, China Aviation Oil Trading Ptd Ltd (“CAOT”) since last December. Xinhua Far East acknowledges that the Company’s investment agreements with CAOHC, BP and Aranda, albeit provisional in nature, present a critical breakthrough in the restructuring process and greatly eliminate the uncertainties about rehabilitation of CAO as a going concern. 1/3 In particular, the rating upgrade factors into Xinhua Far East‘s expectation that BP will expedite the overhaul of CAO’s corporate governance and operations, especially risk management, via its right to nominate two directors in CAO’s board and various co-operative agreements with CAO or CAOHC. Furthermore, Xinhua Far East recognizes that the injection of USD 130 million new capital along with CAO’s robust core business will bolster its financial strength to repay its deferred debt of US$145 million. The rating upgrade also factors into Xinhua Far East’s expectation that CAO will maintain its leading position in jet fuel import business. CAO was incorporated in Singapore in 1993 and went public on the Singapore Exchange (‘SGX’) in December 2001. CAO was the largest jet fuel supplier in China and eighth largest in the world. Its core business is in the procurement of jet fuel for distribution to the China’s civil aviation industry and the Company supplied nearly 100% of imported jet fuel to China. It also owns a 33% stake in Shanghai Pudong International Airport Aviation Fuel Supply Co Ltd (‘SPIA/AFSC’) and purchase of a 5% equity interest in Compania Logistica De Hidrocarburos CLH, S.A. (‘CLH’), Spain’s largest refined products transportation and storage business. In December 2004, CAO incurred huge losses in derivative trading and applied for a Scheme of Arrangement in Singapore court. China Aviation Oil Holding Company (‘CAOHC’) is CAO’s largest shareholder. CAOHC is a large state-owned aviation transportation logistics group and is one of the six civil aviation group companies in China. It is under the direct leadership of China’s State Council. As China’s largest air transportation service enterprise, CAOHC has constructed 155 oil depots at 94 airports with a total storage capacity of 1.4 million cubic meters, forming an independent, complete aviation fuel supply system across the country. In October 2004, CAOHC reduced its interest in CAO from 75% to approximately 60%. BP is one of the world’s largest energy companies with oil and gas businesses in both upstream and downstream sectors. Aranda is an indirect wholly-owned subsidiary of Temasek Holdings (Private) Ltd. Temasek Holdings is the investment arm of Singaporean government and has about US$63 billion in assets under management.
