Press Release, 4 February 2010

OAO TMK announces the launch of approximately US$350 million guaranteed convertible bond offering

OAO TMK ("TMK") announces the launch of an offering of approximately US$350 million principal amount of senior unsecured guaranteed convertible bonds (the "Convertible Bonds") due 2015 convertible into Global Depositary Receipts ("GDRs"), each representing four ordinary shares of TMK (the "Offering"). The Convertible Bonds will be issued by TMK BONDS SA (the "Issuer"), a Luxembourg-incorporated special purpose vehicle, and will be initially guaranteed by TMK, OAO Volzhsky Pipe Plant, a production subsidiary of TMK, and ZAO TMK Trade House, a trading subsidiary of TMK. TMK will procure that OAO Seversky Pipe Plant, OAO Sinarsky Pipe Plant, OAO Taganrog Metallurgical Works and IPSCO Tubulars Inc., four additional production subsidiaries of TMK, will provide further guarantees with respect to the Convertible Bonds within 90 days of closing. The proceeds from the Offering will be used to refinance TMK's existing short-term indebtedness.

The aggregate principal amount of the Convertible Bonds to be issued is expected to be US$350 million, subject to the final terms of the Offering. The Convertible Bonds will be convertible into GDRs, each representing four ordinary shares of TMK, and are expected to carry a coupon of 5.0-5.5 per cent. per annum, payable quarterly in arrear, and to be convertible into GDRs at a premium of 27.5-32.5 per cent. above the reference price (the "Conversion Price"), which will be the placing price in a concurrent placement of GDRs conducted in a bookbuilding process on behalf of potential holders of the Convertible Bonds (the "Placing").

The Convertible Bonds will be issued at 100 per cent. of their principal amount and, unless previously redeemed, converted or cancelled, will mature on the fifth anniversary of the issue, in 2015. Bondholders will have the right to convert their bonds into GDRs of TMK at any point following 41 days after the closing date and before the close of business on the seventh day prior to the final maturity date or, if earlier, ending on the seventh day prior to any earlier date fixed for redemption of the Convertible Bonds. TMK will have the option to redeem the Convertible Bonds after three years from issuance at the principal amount together with accrued interest, if the volume weighted average price of the GDRs traded on the London Stock Exchange exceeds 130 per cent. of the Conversion Price on each of at least 20 dealing days out of 30 consecutive dealing days ending not earlier than five days prior to the notice of redemption. The Issuer will also have the option to call the Convertible Bonds at par plus accrued interest, if 15% or less of the Convertible Bonds remain outstanding. Bondholders will have the right to request redemption of the bonds on the third anniversary following the issue date at the principal amount plus accrued interest. Bondholders will also have puts for, inter alia, certain changes of control, delisting and the failure by TMK to procure further guarantees for the Convertible Bonds from its four additional production subsidiaries, all as more fully described in the terms and conditions of the Convertible Bonds.

In connection with the launch of the Offering, TMK expects to announce a capital increase of its charter capital by way of open subscription (the "Capital Increase") for up to 86,166,871 additional ordinary shares, including the placement of shares to TMK Steel Limited, an indirect majority shareholder of TMK (the "Controlling Shareholder"), through the exercise of the Controlling Shareholder's pre-emptive right in connection with such Capital Increase, at a price per share to be determined based on the reference price of the Offering by the Board of Directors at or around 5 February 2010.

The pricing for the Offering is expected to take place later today or tomorrow and settlement is expected to occur on or around 11 or 12 February 2010.

TMK has made an application to list the Convertible Bonds on the Official List of the UKLA and for the Convertible Bonds to trade on the EEA Regulated Market of the London Stock Exchange.

Initially, the Controlling Shareholder and Rockarrow Investments Limited, a subsidiary of TMK, will lend sufficient GDRs to form the aggregate conversion property of the Convertible Bonds. The Controlling Shareholder is expected to participate in the Capital Increase, which will be sized such that the Controlling Shareholder's loan of GDRs can be satisfied through the replenishment of ordinary shares.

There will be a lock up from the date of pricing to 90 days after the closing date for the Issuer, the Guarantors, the Controlling Shareholder and their respective subsidiaries and controlled affiliates (subject to customary exceptions).

Morgan Stanley, UBS Investment Bank and VTB Capital are acting as Joint Bookrunners in connection with the Offering and the Placing.
