  &lt;p style="text-align: justify;"&gt; &lt;b&gt;a) Sale option of the Nansei Sekiyu refinery&lt;/b&gt;&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; On April 1, 2010 the Sumitomo Corporation informed its interest in exercising the right of sale to Petrobras of 12.5% of the shares of the capital of the Nansei Sekiyu K.K. refinery (Nansei).The remaining shares are already owned by Petrobras since 2008.&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; Petrobras is analyzing the question, based on the terms established in the shareholders&amp;#146; agreement in force.&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; Sumitomo also informed that its interest in the sale of the shares of Nansei is part of the rearrangement of its stake holding in the oil products sector.&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; Nansei has a refinery located in the Japanese province of Okinawa, with a processing capacity of 100 thousand barrels of light petroleum per day, and it produces high quality oil products at the standards of the Japanese market. It also has an oil and oil products terminal for storage of 9.6 million barrels and three wharves capable of receiving Very Large Crude Carriers (VLCC) of up to 280,000 tbp.&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; &lt;b&gt;b) Investment in A&amp;ccedil;&amp;#250;car Guarani S.A.&lt;/b&gt;&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; In April 2010 an investment agreement was executed that establishes the entry of Petrobras Biocombust&amp;iacute;vel into the capital of A&amp;ccedil;&amp;#250;car Guarani S.A., with a capital contribution of US&amp;#36;905 until 2015, when it will then hold 45.7% of the capital shares.&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; The investment will be made in three stages as established in the investment agreement, as follows: &lt;/p&gt;
  &lt;p style="text-align: justify;"&gt;1 &amp;#150; Initial investment of US&amp;#36;383 (R&amp;#36;682 million) through a capital increase in the company Cruz Alta Participa&amp;ccedil;&amp;otilde;es S.A. (a wholly owned subsidiary of Guarani); &lt;/p&gt;
  &lt;p style="text-align: justify;"&gt;2 &amp;#150; Delisting of Guarani with a subsequent exchange by Petrobras Biocombust&amp;iacute;vel of the shares of Cruz Alta for the initial interest of 26.3% in the capital of Guarani.&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; 3 &amp;#150; Additional investment of US&amp;#36;522 (R&amp;#36;929 million) through increases in the capital of Guarani, to be made in a maximum period of five years (until 2015), in order to reach a 45.7% interest in the capital of Guarani.&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; The agreement also establishes additional contributions on the part of the partners up to the limit of a 49% interest by Petrobras Biocombust&amp;iacute;vel.&lt;/p&gt;
&lt;/div&gt;
&lt;div style="PADDING-RIGHT: 0%; PADDING-LEFT: 0%"&gt;
  &lt;p style="text-align: justify;"&gt; &lt;b&gt;c) New partnership for the development of Comperj&lt;/b&gt;&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; On April 28, 2010 Comperj Participa&amp;ccedil;&amp;otilde;es S.A. signed a contract with SMU Energia e Servi&amp;ccedil;os de Utilidades Ltda (SMU) for the creation of a new company, Companhia de Desenvolvimento de Plantas de Utilidades (CDPU), for the purpose of analyzing the execution of the project for Comperj's Utilities Center.&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; CDPU will have a 20% interest in Comperj Participa&amp;ccedil;&amp;otilde;es S/A and an 80% interest in SMU, a Brazilian company with an interest in Sembcorp Utilities PTE Ltd (Singapore), through its wholly-owned subsidiary Sembcorp Utilities (BVI) Pte Ltd, Mitsui &amp;amp; Co. Ltd. (Japan) and Utilitas Participa&amp;ccedil;&amp;otilde;es S.A. (Brazil).&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; The project for the Utilities Center comprises the units for supplying electric power, steam, treatment of water and effluents, as well as hydrogen, and it is also an integral part of the Petrochemical Complex of Rio de Janeiro. Comperj, located in the state of Rio de Janeiro, also forecasts the building of a refinery, and first and second generation petrochemical units. It is forecast to enter into operation in the second semester of 2013.&lt;/p&gt;
  &lt;p style="text-align: justify;"&gt; Among the procedures for installation of Comperj, bidding has been held for the construction of a coke unit, where the winner was the Techint and Andrade Gutierrez consortium. The final amount of the contract was US&amp;#36;1,061 (R&amp;#36;1,890 million).&lt;/p&gt;
