| Tenaris Announces the Approval of its Acquisition of the Remaining Minority Interests in Siderca |
| Luxembourg, April 3, 2003. Tenaris S.A. (NYSE, BASE and Mexico: TS; MTA Italy: TEN), announced today that the Argentine securities regulator has approved its proposal to acquire the remaining minority interests in Siderca S.A.I.C. (Siderca) (BASE: ERCA), which represent approximately 0.89% of Siderca’s outstanding capital stock. Tenaris also announced that Siderca has given notice of termination of the deposit agreement relating to the Siderca ADSs and has instructed JPMorgan Chase Bank, the depositary for the Siderca ADSs, to discontinue the acceptance of Siderca shares for deposit and the issuance of ADSs. |
| In accordance with Argentine law, Tenaris shall unilaterally acquire for cash all the outstanding Siderca shares not held by Tenaris or its affiliates, including any Siderca shares underlying Siderca ADSs, for a purchase price of: |
| • | six Argentine pesos (ARP6.00) per Siderca share; and |
| • | sixty Argentine pesos (ARP60.00) per Siderca ADS. |
| The purchase price for the Siderca shares will be deposited at BBVA Banco Francés S.A., Tenaris’s payment agent for this transaction. These amounts will be made available to holders of Siderca shares beginning on April 8, 2003, in accordance with procedures that will be announced by public notice in at least one Argentine newspaper of wide circulation and through the Buenos Aires Stock Exchange. The purchase price for the shares underlying Siderca ADSs will be converted into U.S. dollars at the free market rate of exchange of Argentine pesos into U.S. dollars and deposited into the account of JP Morgan Chase Bank on April 8, 2003, or as soon as practicable thereafter. |
| In addition, Tenaris has agreed to assign to the holders of the Siderca shares that are being acquired, including shares underlying Siderca ADSs, the dividend of Argentine pesos 0.16 per share (Argentine pesos 1.60 per ADS) proposed by Siderca’s board of directors, in case this dividend is approved by Siderca’s general shareholders’ meeting which will be held in April 2003. Tenaris will announce as soon as practicable the timing and manner of such assigment and its related payment. |
| Notwithstanding the fact that Tenaris’s has the express approval of the Argentine securities’ regulator, four registered holders of Siderca shares, accounting for 0.01% of Siderca’s total share capital, have presented a petition to halt the unilateral acquisition of their shares by Tenaris. This petition does not in any way affect the right of Tenaris to acquire the shares belonging to other shareholders nor the right of those shareholders to receive due payment for those shares in accordance with this notice. |
| This communication does not constitute an offer or solicitation for the sale, purchase or acquisition of securities of Siderca or Tenaris in any jurisdiction. |
