  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;b&gt;&lt;font size="2"&gt;18. Acquisition/Sales of Assets and Interests&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;b&gt;&lt;font size="2"&gt;a) Sale option of the Pasadena refinery by Astra&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;In a decision reached on April 10, 2009, in the existing arbitration process between Petrobras America Inc - PAI and others and Astra Oil Trading NV -ASTRA and others, the exercise of the put option by ASTRA with respect to PAI, of the remaining 49.13% of the shares of ASTRA in Pasadena Refinery Systems Inc. (&amp;quot;PRSI&amp;quot;), was considered valid.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;According to the decision reached on April 10, 2009, the consideration to acquire the remaining shareholding interest in the refinery and in the trading company in Pasadena was fixed at US$466. There is still a pending consideration, regarding the acquisition of the shares, which will be made by Petrobras to Astra in September, 2010 in the amount of US$85.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;In March 2009, a loss was recognized in the amount of US$147, corresponding to the difference between the fair value of the net assets and the value defined by the arbitration panel. As a result of this decision, the Company recorded a charge of US$289 in Additional Paid in Capital due to the acquisition of the remaining 49.13% of the shares of ASTRA in Pasadena Refinery Systems Inc. (&amp;quot;PRSI&amp;quot;).&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;There are still judicial proceedings ongoing asking for indemnifications by both parties and others revindications.&lt;/font&gt;&lt;/p&gt;
&lt;/div&gt;&lt;br&gt;&lt;/br&gt;
&lt;div style="PADDING-RIGHT: 0%; PADDING-LEFT: 0%; WIDTH: 100%"&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;b&gt;&lt;font size="2"&gt;b) Investment agreement between Petrobras, Petroquisa, Braskem, Odebrecht and Unipar&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On January 22, 2010, Petrobras and Odebrecht entered into an agreement to consolidate all petrochemical interests of both companies into Braskem, which resulted in the following transactions up to the third quarter of 2010.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;In April 2010, Petrobras contributed to Braskem approximately US$1,388, through an affiliate, as a result of a private subscription.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On April 27, 2010, Braskem acquired from Unipar 60% of Quattor Participa&amp;#231;&amp;#245;es and, on May 10, 2010, 100% of Unipar Comercial and 33.33% of Polibutenos.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On June 18, 2010, shares representing 40% of interest in Quattor Participa&amp;#231;&amp;#245;es S.A. held by Petrobras were exchanged by 18,000,087 new common shares issued by Braskem. The exchange was accounted for in accordance with ASC 860 &amp;quot;Transfers and Servicing&amp;quot;, based on the fair value of the interest received from Braskem at the date of the transaction. As a result of the transaction a loss of US$226, net of tax, was recognized.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On August 17, 2010, Braskem transferred 1,515,433 of its preferred shares for a nominal amount in order to accomplish the terms of the agreement.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On August 30, 2010, shares representing 10% of interest in Rio Pol&amp;#237;meros S.A. held by Petrobras were exchanged into 1,280,132 new preferred shares issued by Braskem. The exchange was accounted for in accordance with ASC 860 &amp;quot;Transfers and Servicing&amp;quot;, based on the fair value of the interest received from Braskem at the date of the transaction. As a result of the transaction a loss of US$ 46, net of tax, was recognized.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;As a result of the abovementioned transactions, Petrobras increased its interest in Braskem from 25.41% to 36.1% throughout 2010.&lt;/font&gt;&lt;/p&gt;
&lt;/div&gt;&lt;br&gt;&lt;/br&gt;
&lt;div style="PADDING-RIGHT: 0%; PADDING-LEFT: 0%; WIDTH: 100%"&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;b&gt;&lt;font size="2"&gt;c) Acquisition and partnerships in the ethanol market&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;&amp;#149;&lt;/font&gt;&lt;b&gt;&lt;font size="2"&gt;Total Agroind&amp;#250;stria Canavieira S/A&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;In 2010, Petrobras acquired interest in an ethanol refinery by contributing US$77 into the capital of Total Agroind&amp;#250;stria Canavieira S/A, pursuant to the commitment established in the Special General Shareholders&amp;#146; Meeting of December 22, 2009, to pay in the amount of US$89 not later than March 2011, when it will then hold 40.4% of the capital.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;&amp;#149;&lt;/font&gt;&lt;b&gt;&lt;font size="2"&gt;S&amp;#227;o Martinho S/A&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On June 18, 2010, Petrobras entered into an investment agreement with Grupo S&amp;#227;o Martinho S.A., in order participate in certain ethanol refineries located in Goias. Petrobras will hold 49% of the investment after 12 months by a capital contribution US$234.&lt;/font&gt;&lt;/p&gt;
&lt;/div&gt;&lt;br&gt;&lt;/br&gt;
&lt;div style="PADDING-RIGHT: 0%; PADDING-LEFT: 0%; WIDTH: 100%"&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;b&gt;&lt;font size="2"&gt;d) Investment in A&amp;#231;&amp;#250;car Guarani S.A.&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On April 30, 2010, an investment agreement established the entry of Petrobras into the capital of A&amp;#231;&amp;#250;car Guarani S.A., by a capital contribution of US$894 until 2015, when it will then hold 45.7% of the capital shares. A&amp;#231;&amp;#250;car Guarani S.A. is engaged in sugar cane processing focused on the ethanol and sugar market.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On May 14, 2010, Petrobras contributed US$379 into the capital of Cruz Alta Participa&amp;#231;&amp;#245;es S.A (a wholly owned subsidiary of Guarani). As a result of the contribution, Petrobras has 49% of interest in Cruz Alta Participa&amp;#231;&amp;#245;es S.A &lt;/font&gt;&lt;b&gt;&lt;font size="2"&gt;.&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On August 13, 2010 the corporate restructuring was concluded, where Tereos Internacional incorporated the shares of Guarani, which became a wholly owned subsidiary. After this restructuring there are corporate acts in progress which will promote the replacement of the shares of Cruz Alta by shares of Guarani.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;b&gt;&lt;font size="2"&gt;e) Increase of interest in the capital of Breitener Energ&amp;#233;tica S.A.&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On December 31, 2009, Petrobras had 30% of the capital of Breitener Energ&amp;#233;tica S.A., a company established for the purpose of generating electric power, located in the city of Manaus, in the state of Amazonas. On February 12, 2010, Petrobras obtained control of Breitener by acquiring an additional 35% of interest for US$2. As a result of the acquisition, Petrobras has 65% of interest in Breitener Energ&amp;#233;tica S.A. Due to immateriality, proforma information has not been presented.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;b&gt;&lt;font size="2"&gt;f) Sale option of the Nansei Sekiyu refinery&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On April 1, 2010 the Sumitomo Corporation announced its interest in exercising the right of sale to Petrobras, through its wholly owned subsidiary Petrobras Internacional Braspetro B.V., &amp;#147;PIBBV&amp;#148;, of 12.5% of the shares of the capital of the Nansei Sekiyu K.K. refinery (Nansei). The remaining shares (87.5%) are already owned by PIBBV since 2008.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;The share purchase agreement was signed on September 29, 2010, and on October 20, 2010 the payment was made in the amount equivalent to US$29 (R$48,843 thousand - JPY 2,365,268 thousand ), through the delivery of the shares.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;As a result of the exercise of the right of sale by Sumitomo Corporation, a loss was&lt;/font&gt; &lt;font size="2"&gt;recognized in the amount of US$10 corresponding to the difference between the fair value of the shares and the estimated purchase price.&lt;/font&gt;&lt;/p&gt;
&lt;/div&gt;&lt;br&gt;&lt;/br&gt;
&lt;div style="PADDING-RIGHT: 0%; PADDING-LEFT: 0%; WIDTH: 100%"&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;b&gt;&lt;font size="2"&gt;g) Acquisition of G&amp;#225;s Brasiliano Distribuidora S.A.&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On May 26, 2010 Petrobras S.A., through its subsidiary Petrobras G&amp;#225;s S.A. (Gaspetro), entered into an agreement with Enti Nazionale Idrocarburi S.p.A. (ENI) for acquisition of 100% of the shares of Gas Brasiliano Distribuidora S.A. (GBD), for the approximate amount of US$250, subject to adjustments due to the value of the company&amp;#146;s working capital on the date of settlement of the transaction.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;Transfer of the control will be made only after the conclusion of the transaction, which is subject to approval by the Regulatory Agency for Sanitation and Energy of the State of Sao Paulo (ARSESP).&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;b&gt;&lt;font size="2"&gt;h) Sale of the San Lorenzo refinery and part of the distribution network in Argentina&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On May 4, 2010, Petrobras Argentina S.A. (formerly Petrobras Energia S.A.) approved the terms and conditions of the agreement for the sale to Oil Combustibles S.A. of refining and distribution assets in Argentina. The deal comprises a refinery located in San Lorenzo in the province of Santa F&amp;#233;, a fluvial unit and a fuel trading network connected to this refinery, consisting of 360 sales points and associated wholesaler clients.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;The offer for the aforementioned assets was approximately US$36. In addition, on the closing date the petroleum inventories and the different products will be sold to Oil Combustibles for approximately US$74. The total amount of the transaction is estimated at around US$110.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;The transaction is in the process of approval by the administrative authorities required by the prevailing legislation in Argentina.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;The transaction does not consider the sale of the reformer unit that Petrobras Argentina has in its Puerto General San Mart&amp;#237;n Petrochemical Complex.&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;&lt;b&gt;i) Bio&amp;#243;leo Industrial e Comercial S.A&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;On August 24, 2010, Petrobras paid the amount of US$9 into the capital of Bio&amp;#243;leo Industrial e Comercial S.A., through the purchase and sale of shares and now holds 50% of the capital. Bio&amp;#243;leo is a company for extracting vegetal oils, located in the city of Feira de Santana, in the State of Bahia.
&lt;/font&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;&lt;/font&gt;&lt;font size="2"&gt; Additionally, transfers of US$4 were made for operating and security, environment and health (SMS) improvements, paid out in August 2010 in equal parts by the partners.&lt;/font&gt;&lt;/p&gt;
&lt;/div&gt;&lt;br&gt;&lt;/br&gt;

  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;b&gt;&lt;font size="2"&gt;j) Variable interest entities&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
  &lt;p style="TEXT-ALIGN: justify"&gt;&lt;font size="2"&gt;During 2010 Petrobras exercised options to acquire all the shares from non-controlling owners of certain Variable Interest Entities, which were previously consolidated. In accordance with ASC 810, these acquisitions were accounted for in equity attributable to Petrobras.&lt;/font&gt;&lt;/p&gt;
