Item 3. Source and Amount of Funds or Other Consideration On December 21, 2004, Pampa acquired 6,000,000 Series A Shares on the Chilean Stock Exchange for an aggregate purchase price of Ch$24,006,000,000. Yara loaned Pampa the funds necessary to complete the acquisition. In order to secure the loan from Yara, Pampa issued notes to Yara in the amount of US$43,000,000 (the "Notes"). On January 10, 2005, Pampa repaid Yara the full amount due under the Notes with the proceeds of a loan from Banco BCI, which matures on May 30, 2012 and accrues interest at an annual rate of 6.56%. 14 On January 14, 2005, SQYA acquired 6,145,092 Series A Shares on the Chilean Stock Exchange for an aggregate purchase price of Ch$24,592,658,184. Yara and Banco BCI loaned SQYA the funds necessary to complete the acquisition. In order to secure the loans from Yara and Banco BCI, SQYA issued notes to Yara and Banco BCI in the amounts of US$30,000,000 and US$20,000,000, respectively. The notes issued to Yara mature on May 30, 2015 and accrue interest at an annual rate of 6.65%. The notes issued to Banco BCI mature on May 30, 2011 and accrue interest at an annual rate of 6.40%. Pampa originally acquired ownership of 53,557,332 Series A Shares prior to SQM's registration with the Securities Exchange Commission with funds received from bank loans and capital contributions of its affiliates. On June 4, 2006, Pampa initiated a tender offer in Chile for Series B Shares. The tender offer was consummated on July 3, 2006, and in connection with the tender offer Pampa acquired 6,207,539 Series B shares for an aggregate purchase price of Ch$35,072,595,350. The source of funds for the acquisition of shares include (i) affiliate contributions in the amount of Ch$13,602,595,350; (ii) a loan from Banco Santander Santiago in the amount of US$30,000,000, which matures in 180 days from June 4, 2006 (this loan is in the process of being refinanced with a new loan from Banco Santander Santiago, which is expected to mature in June 2012); (iii) a loan from Banco BCI in the amount of US$6,500,000, which matures in June 2012 and (iv) a loan from Banco Corpbanca in the amount of US$6,500,000, which matures in June 2012. The average annual interest rate on these three loans is 7.19%. Item 4. Purpose of Transaction Pampa and SQYA undertook the purchase of additional shares of Series A Shares in order to increase their interest in SQM. The interests of Pampa, SQYA and the Reporting Persons in SQM were acquired solely for the purpose of investment. Pampa purchased the Series B Shares in order to increase Mr. Ponce's indirect combined ownership in SQM to over 25% for investment purposes so that he would be deemed, solely for purposes of Chilean law, as a "controlling shareholder" under Articles No. 97 and No. 99 of the Chilean Securities Market Law. The acquisition by Pampa of the Series B Shares, however, did not materially affect the Reporting Persons' control rights over SQM since the Series B Shares have limited voting rights (holders of Series B Shares elect one of eight members of the Board of Directors (the "Series B Director") and vote together with the Series A Shares on other matters); the Reporting Persons' ownership of 5.16% of the Series B Shares does not allow them to materially influence the election of the Series B Director and their increased ownership, on a combined basis, of Series A and Series B Shares from 24.97% to 27.33% does not materially increase their voting power with respect to other matters. Although being deemed as a "controlling shareholder" for purposes of Chilean law does not provide additional control rights, it does result, under Chilean corporate law, in the "controlling shareholder" not being required to extend a mandatory public tender offer upon subsequent purchases of securities of the Company. Each of the Reporting Persons intends to review its investment in SQM on a regular basis and, as a result thereof, may at any time or from time to time determine, either alone or as part of a group, (a) to acquire additional securities of SQM, through open market purchases, privately negotiated transactions or otherwise, (b) to dispose of all or a portion of the securities of SQM owned by it in the open market, in privately negotiated transactions, in one or more registered public offerings or otherwise, or (c) to take any other available course of action, which could involve one or more of the types of transactions or have one or more of the results described in the next paragraph of this Item 4. Notwithstanding anything contained herein, each of the Reporting Persons specifically reserves the right to change its intention with respect to any or all of such matters. In reaching any decision as to its course of action (as well as to the specific elements thereof), each of the Reporting Persons currently expects that it would take into consideration a variety of factors, including, but not limited to, the following: SQM's business and prospects; other developments concerning SQM and its businesses generally; other business opportunities available to the Reporting Persons; changes in law and government regulations; 15 general economic conditions; and financial and stock market conditions, including the market price of the Series A and Series B Shares. Except as set forth in this Item 4, the Reporting Persons have no present plans or proposals that relate to, or that would result in, any of the actions specified in clauses (a) through (j) of Schedule 13D of the Exchange Act.

In order to set the terms and conditions governing their joint ownership of SQYA, Inversiones SQ Holding S.A. ("SQ Holding") (predecessor entity of SQH) and Norsk Hydro Holland B.V. ("Norsk") entered into the Shareholders Agreement of Inversiones SQNH S.A. (predecessor entity of SQYA) dated April 18, 2002 (the "Shareholders Agreement"). Pursuant to the Shareholders Agreement, SQ Holding and Norsk agree that Norsk, as the then-owner of 49% of the share capital of SQYA, had the right to designate at least one person to be elected to the boards of directors of Norte, Oro, Pampa and SQM. SQ Holding and Norsk further agreed that any of their votes remaining after electing a person designated by Norsk to the boards of Norte, Oro, Pampa and SQM would be used to elect three directors designated by SQ Holding to the boards of Norte, Oro and Pampa and two directors designated by SQ Holding to the board of SQM. Under the Shareholders Agreement, SQ Holding and Norsk further agreed that the president of SQM would always be designated by SQ Holding. On September 15, 2004, Yara acquired Norsk's interest in SQYA and assumed all of Norsk's rights and obligations under the Shareholders Agreement. On November 9, 2005, the shareholders of SQ Holding resolved to split SQ Holding into two companies, SQ Holding (surviving entity) and SQH (newly formed entity).
