Notice to US Holders of Polymetal Shares or Polymetal GDRs

The Institutional Share Swap Facility is being made for the securities of a company incorporated outside of the United States. The Institutional Share Swap Facility is subject to disclosure requirements of a foreign country that are different from those of the United States. Financial statements, if any, included in the documents relating to the Institutional Share Swap Facility have been prepared in accordance with foreign accounting standards that may not be comparable to the financial statements of United States companies.

It may be difficult for you to enforce your rights and any claim you may have arising under the U.S. federal securities laws, since the Company and PMTL are located in foreign countries, and some or all of their officers and directors may be residents of foreign countries. You may not be able to sue a foreign company or its officers or directors in a foreign court for violations of the U.S. securities laws. It may be difficult to compel a foreign company and its affiliates to subject themselves to a U.S. court's judgment.

You should be aware that the Company and PMTL may purchase securities otherwise than under the Institutional Share Swap Facility, such as in open market or privately negotiated purchases.

The Institutional Share Swap Facility is not being made available to residents of Connecticut, Illinois, Massachusetts, Maryland or Oregon save to certain exempt institutional investors, as further set forth on the website for Polymetal International and in the ISSF Offer Document.
