Santiago, May 12, 2004 Mr. Alejandro Ferreiro Y. Superintendent Securities and Insurance Superintendence Avda. Libertador Bernardo O'Higgins 1449 Santiago -------- ESSENTIAL ISSUE Dear Mr. Superintendent. We hereby refer to your Memorandum Number 02853, dated April 6, 2004, and to our answer to the same, dated April 8, 2004 and, as an update, we hereby inform you the following: 1. Sociedad Quimica y Minera de Chile S.A. ("SQM") and Distrinor S.A. ("Distrinor") subscribed, on May 22, 2001, a Natural Gas Supply Contract, of a "fixed nature", pursuant to which Distrinor, among other aspects, is required to supply and sell to SQM -for a period of 10 years beginning on June 1, 2001- all the natural gas SQM requires for "heat generation" at its industrial facilities located in Chile's Second Region and that the parties have estimated to be of approximately 3,850,000 million Btu per year. 2. Distrinor has recently informed SQM that, as of this date and for the remainder of May, it will reduce the natural gas supply it has been providing SQM from approximately 240 thousand cubic meters per day to a new amount of approximately 100 thousand cubic meters per day. To that effect, Distrinor has invoked a force majeure reason as the basis for its decision, which, in turn, is based on the restrictions that Distrinor's natural gas supplier is allegedly experiencing due to the export restrictions supposedly imposed by the Argentinean Government on natural gas exports. 3. Distrinor has also informed SQM that, if the restriction criteria that is being supposedly imposed by the Argentinean authorities remains unchanged, the status of the natural gas supply provided by Distrinor to SQM should be normalized, partially during June and fully during July 2004. 4. SQM is prepared to immediately replace, as an alternative energy source, natural gas consumption by diesel. Therefore, SQM will be able to meet its annual production and sales programs. 5. SQM is currently carrying out the necessary investments that will allow it to adapt, during the fourth quarter of 2004, the relevant equipment to operate with fuel oil, instead of diesel. Fuel oil costs are substantially lower than the costs of diesel. 6. SQM estimates that the lower natural gas consumption and the higher diesel consumption will translate, for the remainder of this month, in increased production costs that are currently being assessed. This higher cost will later be reduced as Distrinor increases the supply of natural gas to SQM and to the extent that SQM is able to use fuel oil as an alternative energy source. 7. SQM will carry out all the applicable actions against Distrinor and third parties involved to request their contractual obligations and indemnifications. We inform you the above as an essential issue and in compliance with articles 9 and 10 of Law number 18.045. Additionally, also in compliance with the indications set forth in the Rule of General Character Number 30 that was issued on November 10, 1989. We remain at your disposal to clarify any additional aspects that you may deem relevant in relation to the above. Yours truly, Sociedad Quimica y Minera de Chile S.A.
