With a view to increasing the liquidity of the Option shares and their visibility to the US investors, Option has decided to implement a Level I American Depositary Receipts ("ADR") Program. An F-6 registration statement has been filed with The Securities and Exchange Commission.

This Level I ADR Program has the following characteristics: 

• ADRs are U.S. securities issued by a depositary bank representing shares of a non-US company. In this case, The Bank of New York has been selected as depositary bank;
• An ADR gives, investors a voting right and future dividend rights according to the terms and conditions of the deposit agreement entered into between The Bank of New York, Option and future ADR holders;
• An ADR gives US investors access to the Option shares through the over-the-counter market on which ADRs are freely negotiable in the US.

Institutional investors and brokers that do not have the capability to trade in the local market should contact Jason Paltrowitz, who will put them in touch with a market maker. This market maker will quote the investor a price and execute the trade with the appropriate charges on a one-time basis, even if this particular market maker does not choose to file the Form 211, commit the requisite capital, and post a public, binding quote on an ongoing basis.

Retail investors should refer to their local broker for a price on the ADR and trade execution. If the broker cannot price the stock because they do not work with a market maker, the broker should contact Jason Paltrowitz as indicated above.
