The average annual interest rate on these three loans is 7.19%.

As described in Schedule I, on various dates from November 8, 2006 to December 20, 2006, Pampa purchased on the open market 7,758,446 Series B Shares for an aggregate purchase price of Ch$55,507,557,750. The source of funds for the acquisition of these shares was (i) a loan from Banco Santander Santiago in the amount of US$14,495,000, which matures on February 18, 2007 and accrues interest at an annual rate of 7.56%; (ii) a loan from BCI in the amount of US$8,500,000, which matures on February 7, 2007 and accrues interest at an annual rate of 7.88%; (iii) a loan from Banco Scotiabank in the amount of US$30,000,000, which matures on February 19, 2007 and accrues interest at an annual rate of 6.4%, (iv) a loan from Banco Corpbanca in the amount of US$24,256,000, which matures February 2007 and accrues interest at an annual rate of 6.6% and (v) a capital increase on December 12, 2006 which raised approximately US$37,600,000 of which US$27,749,000 was used for the acquisition of shares.

Item 4. Purpose of Transaction

The Reporting Persons undertook the purchases of Series A Shares and Series B Shares listed above in Item 3 in order to increase their interest in SQM and for investment purposes.

Pampa purchased the Series B Shares on July 3, 2006 in order to increase Mr. Ponce Lerou’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). 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.

Pampa purchased additional Series B Shares for investment purposes on the open market on various dates ranging from November 8, 2006 to December 20, 2006, and on December 22, 2006, entered into the Kowa Shareholders Agreement, as described in Item 6 hereof, in order to maintain Mr. Ponce Lerou’s position of “controlling shareholder” under Articles No. 97 and No. 99 of the Chilean Securities Market Law. For the reasons described in the preceding paragraph, these transactions did not materially affect the Reporting Persons’ control rights over SQM. The Reporting Persons’ together with the Grupo Miwa Reporting Persons’ combined ownership of 11.64% 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 27.33% (in the case of the Reporting Persons) to 32.30% (in the case of the Reporting Persons together with Grupo Miwa Reporting Persons) does not materially increase their voting power with respect to other matters.

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; 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.
