         NOTICE IS HEREBY GIVEN to Holders of American Depositary Receipts
("ADRs") of CRISTALERIAS DE CHILE S.A. that, pursuant to Section 6.02 of the
Amended and Restated Deposit Agreement, dated October 9, 2000 with respect to
the Company's ADRs (the "Deposit Agreement"), among CRISTALERIAS DE CHILE
S.A., The Bank of New York, as Depositary (the "Depositary") and the Owners
and Beneficial Owners of ADRs issued thereunder, the Deposit Agreement will be
terminated effective June 21, 2005 (the "Termination Date").

         If any ADRs remain outstanding after the Termination Date,
registration of transfers of ADRs will be discontinued, distribution of
dividends will be suspended, and the Depositary will give no further notices
or, subject to certain limited exceptions, perform any further acts under the
Deposit Agreement.

         As a result of the termination of the Deposit Agreement described
above, you have until December 21, 2005 to decide if you would like to retain
your interest in shares of the Issuer. If you do not surrender your ADRs and
request delivery of the underlying Issuer shares by 5:00 p.m., New York City
time, on December 21, 2005, the Depositary will use reasonable efforts to sell
those shares on or about December 22, 2005, and you will receive the net
proceeds of sale upon subsequent surrender of your ADRs.

         If you surrender your ADRs for the purpose of withdrawing the
underlying Issuer shares by December 21, 2005, you must pay the fee of the
Depositary as provided in Section 2.05 of the Deposit Agreement of up to $5.00
per 100 ADRs (or portion thereof) surrendered, a cable fee of $12.50, and any
applicable taxes or governmental charges. Payment should be made to The Bank
of New York.

         If you surrender your ADRs to obtain payment of proceeds of sale of
Issuer shares after December 21, 2005, the fee of the Depositary as provided
in Section 2.05 of the Deposit Agreement of up to $5.00 per 100 ADRs (or
portion thereof) surrendered, the expenses of sale and any applicable taxes or
governmental charges will be deducted from the payment you will receive.

         For Registered Holders wishing to surrender ADRs, the address of the
Depositary is: The Bank of New York, 101 Barclay Street, Floor 22 West, New
York, NY 10286. Registered or overnight mail is the suggested method of
delivering ADRs to the Depositary. Beneficial Holders should deliver ADRs
