      modifying the ratio of ordinary shares to series B ADRs from the current ratio
      of 10:1 to a new ratio of 1:1. From the perspective of the series B ADR holder,
      the ratio change has the same effect as a ten-for-one share split, and series
      B
      ADR holders will receive nine additional series B ADRs for every series B ADR
      held. There will be no change to SQM underlying ordinary shares traded on the

      than 1% of SQM's outstanding shares were held by series A ADR holders. SQM
      intends to delist the series A ADRs from the NYSE on or about March 27, 2008.

      7,
      2008, SQM will provide formal notice to the Bank of New York Mellon that the
      ADR-A Facility will be terminated. Once the Bank of New York Mellon receives
      formal notice of the termination of the ADR-A Facility, it will establish a
      termination date, which will be no sooner than 90 days from the date of that
      notice. Upon termination, holders of series A ADRs will have one year to decide
      if they would like to exchange their series A ADRs for ordinary shares of SQM.
      If a holder of series A ADRs does not exchange his or her shares within the
      one-year holding period, the Bank of New York Mellon will be authorized to
      sell
      the remaining shares and deliver to such holder the net proceeds from the sale
