================================================================================

(1)    The filing fee has been calculated pursuant to Rule 0-11(d) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), based upon
U.S. $25.00 per American Depositary Share ("ADS") with respect to 20,734
outstanding ADSs as of July 30, 2001, excluding ADSs beneficially owned by IVAX
Corporation ("IVAX") or its affiliates. The number of outstanding ADSs is based
upon information provided to the bidder by Laboratorio Chile S.A. ("LabChile").
Based upon information provided to the bidder by LabChile, there are no shares
of common stock, no par value (the "Shares"), excluding Shares represented by
ADSs and Shares beneficially owned by IVAX or its affiliates, held by U.S.
holders, as defined in Rule 14d-1(d) under the Exchange Act. Therefore, no fee
is being paid with respect to the acquisition of Shares.

(2)    The filing fee was paid on July 31, 2001, when the Schedule TO was
