2 Qatar Petroeum (QP), a state-owned corporation estabished in 1974, is responsibe for a phases of the oi and gas industry in Qatar. The principa activities of Qatar Petroeum and its subsidiaries and joint ventures cover exporation, driing and production operations, transport, storage, marketing and sae of crude oi, natura gas iquids, iquefied natura gas, gas-to-iquids, refined products, petrochemicas and fertiizers, and heicopter and financia services. Qatar Petroeum s strategy of conducting hydrocarbon exporation and new projects is through Exporation and Production Sharing Agreements (EPSA) and Deveopment and Production Sharing Agreements (DPSA) concuded with major internationa oi and gas companies. Thriving on a spirit of enterprise, each of our joint ventures is underpinned by transparency, innovation and determination to achieve unparaeed standards of both quaity and service. The operations and activities of Qatar Petroeum are conducted on various onshore ocations, which incude Doha, Dukhan, Mesaieed and Ras Laffan industria cities, as we as offshore areas incuding Hau Isand, offshore production stations, driing patforms and the North Gas Fied. Qatar Petroeum is committed to its part as both a concerned partner and affiiate to the protection, preservation and conservation of the natura environment, whie ensuring that the company s empoyees and the genera pubic ive in a cean, safer word. w w w. q p. c o m. q a

3 United Deveopment Company PSC (UDC) is one of Qatar s eading private sector sharehoding companies. UDC s mission is to identify and invest in ong-term projects contributing to Qatar s growth and providing good sharehoder vaue. The company was estabished in 1999 and isted on the Qatar Exchange in June It has an authorized share capita of QR biion, tota assets of QR biion as of 31 March 2011 and a market capitaization of check current vaue on Qatar Exchange. UDC s target areas of interest incude: infrastructure, energy-intensive industries, hydrocarbon downstream manufacturing, rea estate, maritime and environment-reated businesses, urban deveopment and utiities, hospitaity, retai and fashion, information technoogy, media and communications, insurance and other services. From day one, the Company s mission has been to become a cornerstone in the deveopments of Qatar and the region, creating asting vaue and maximizing returns for partners and sharehoders. Through a combination of project activities and commercia enterprise, UDC has deveoped into the first-choice private sector and joint venture partner for internationa investors in Qatar, and has successfuy estabished severa new companies and investment vehices across the region. Due in great measure to the unique conditions for sustainabe economic activity in Qatar created by the country s eadership under His Highness the Emir, Sheikh Hamad Bin Khaifa A Thani, UDC has estabished a stabe business patform generating weath and returning vaue through investment and joint venture activities. Since 1999, UDC has moved from researching projects into deveopment, production and operations. Project research has ed to the creation of companies, considered to be among the most successfu in their reated fieds. The Company prides itsef in its abiity to create quaity investment opportunities, both at home and overseas. UDC s founders and current Board Members are among Qatar s most successfu investors and deveopers. Qatari sharehoders own 75 percent of the Company s tota shares whie the remaining 25 percent are hed by internationa investors. The Company continues its quest for exceence and progress by identifying and adding new investments and partnerships to its diversified portfoio of exceent businesses. w w w. u d c q a t a r. c o m

10 ABOUT QATAR Qatar is a peninsua of sq. Km. ocated hafway down the west coast of the Arabian Guf. The Emir, His Highness Sheikh Hamad Bin Khaifa A Thani, is the ruer of Qatar and is the head of the constitutiona authorities, hoding both egisative and executive powers. Oi and gas have given Qatar one of the highest per capita incomes in the word and made it one of the fastest-growing economies. Dispaying an enightened approach to prosperity, Qatar is channeing its weath not into trophy assets but into funding the advancement of cuture, science, and education. Its strategic path towards a posthydrocarbon economy wi be through a vibrant, knowedge-based society. Energetic and ambitious, the State of Qatar has emerged from virtua anonymity to become one of the most forward-thinking nations in the Midde-East, with increasing regiona and goba infuence. Latest estimates put Qatar s popuation at more than 1.5 miion. By 2030, Qatar aims to be an advanced society capabe of sustaining its deveopment and providing a high standard of iving for a of its peope. Qatar s Nationa Vision defines the ong-term outcomes for the country and provides a framework within which nationa strategies and impementation pans can be deveoped.
