Consolidated Condensed Interim Financial Statements for the three-month period ended March 31, 2006 -------------------------------------------------------------------------------- NOTES TO THE CONSOLIDATED CONDENSED INTERIM FINANCIAL STATEMENTS (In the notes all amounts are shown in U.S. dollars, unless otherwise stated) 1 General information and basis of presentation Tenaris S.A. (the "Company" or "Tenaris"), a Luxembourg corporation (societe anonyme holding), was incorporated on December 17, 2001 as a holding company for investments in steel pipe manufacturing and distribution companies. The Company consolidates its subsidiary companies, as detailed in Note 31 to the audited Consolidated Financial Statements for the year ended December 31, 2005, and modified as discussed in Note 8 to these consolidated condensed interim financial statements. These consolidated condensed interim financial statements have been prepared in accordance with IAS 34, "Interim Financial Reporting". The accounting policies used in the preparation of these consolidated condensed interim financial statements are consistent with those used in the audited consolidated financial statements for the year ended December 31, 2005. These consolidated condensed interim financial statements should be read in conjunction with the audited Consolidated Financial Statements for the year ended December 31, 2005, which have been prepared in accordance with International Financial Reporting Standards ("IFRS"). The preparation of consolidated condensed interim financial statements in conformity with IFRS requires management to make certain accounting estimates and assumptions that might affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the balance sheet dates, and also the reported amounts of revenues and expenses for the reported periods. Actual results may differ from these estimates. Material intercompany transactions and balances between Tenaris subsidiaries have been eliminated in consolidation. However, some financial gains and losses do arise from intercompany transactions because certain subsidiaries use their respective local currencies as their functional currency for accounting purposes. Such gains and losses are included in the consolidated income statement under Financial income (expense), net. The Company applies hedge accounting treatment for certain qualifying financial instruments. These transactions are classified as cash flow hedges (mainly currency forward contracts on highly probable forecast transactions and interest rate swaps). The effective portion of the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in equity. The gain or loss relating to the ineffective portion is recognized in the income statement. The fair value of the Company's derivative financial instruments (asset or liability) is reflected on the Balance Sheet. For transactions designated and qualifying for hedge accounting, the Company documents at the time of designation of the transaction the relationship between hedging instruments and hedged items, as well as its risk management objectives. The Company also documents its assessment at hedge designation and at each period end whether the derivatives that are used in hedging transactions are expected to be effective in offsetting changes in cash flows of hedged items. At March 31, 2006, the effective portion of designated cash flow hedges amounts to $0.4 million and is included in Other reserves in equity. Upon the adoption of IFRS 3, which was adopted together with the revised IAS 38, "Intangible Assets", and IAS 36, "Impairment of Assets", previously accumulated negative goodwill is required to be derecognized through an adjustment to retained earnings. The derecognition of negative goodwill in this manner resulted in an increase of $110.8 million in the beginning balance of the Company's equity at January 1, 2005. These consolidated condensed interim financial statements were approved for issue by the Tenaris Board of Directors on May 2, 2006. 6 Tenaris S.A.

Significant changes or events since the date of the annual report are the following: (i) Commitments (a) In August 2001, Dalmine Energie S.p.A. ("Dalmine Energie") entered into a ten-year contract ending October 1, 2011 with Eni S.p.A. Gas & Power Division ("Eni") for the purchase of natural gas with certain take-or-pay conditions. The outstanding value of these commitments at March 31, 2006 amounts to approximately EUR 770.2 million ($932.3 million). (b) Under the Gas Release Program enacted by Eni, in August 2004, Dalmine Energie increased its supply of natural gas for the period from October 1, 2004 to September 30, 2008. The gas purchase and sale agreements entered into with Eni contain customary take-or-pay conditions. The additional gas supply mentioned above is valued at approximately EUR 247.5 million ($299.6 million), based on prices prevailing at March 2006. Dalmine Energie has also obtained the necessary capacity on the interconnection infrastructure at the Italian border to transport the natural gas to Italy for the supply period. (c) Dalmine Energie has entered into arrangements and expects to obtain additional gas transportation capacity on the Trans Austria Gasleitung GmbH ("TAG") pipeline, which is presently under construction. This capacity will allow Dalmine Energie to import an incremental 1,176.5 million cubic meters of natural gas per year. The additional transportation capacity, which is subject to "ship or pay" provisions, will be available on a firm basis on the TAG pipeline beginning October 2008 and through September 2028. The expected annual value of this "ship or pay" commitment is approximately EUR 5.0 million per year. Tenaris provided bank guarantees in the amount of EUR 15.1 million in support of Dalmine Energie. The value of the bank guarantees corresponds to the termination penalties that would be due TAG in the event of termination or non-utilization of the transportation capacity. 9 Tenaris S.A. Consolidated Condensed Interim Financial Statements for the three-month period ended March 31, 2006 -------------------------------------------------------------------------------- 7 Contingencies, commitments and restrictions to the distribution of profits (Cont'd) (ii) Restrictions to the distribution of profits and payment of dividends As of March 31, 2006, shareholders' equity as defined under Luxembourg law and regulations consisted of the following: (all amounts in thousands of U.S. dollars) Share capital 1,180,537 Legal reserve 118,054 Share premium 609,733 Retained earnings including net income for the three month period ended March 31, 2006 1,173,773 ----------- Total shareholders equity according to Luxembourg law 3,082,097 =========== At least 5% of the net income per year as calculated in accordance with Luxembourg law and regulations must be allocated to the creation of a legal reserve equivalent to 10% of share capital. As of March 31, 2006, this reserve is fully allocated and additional allocations to the reserve are not required under Luxembourg law. Dividends may not be paid from this reserve. Tenaris may pay dividends to the extent, among other conditions, that it has distributable retained earnings calculated in accordance with Luxembourg law and regulations. At March 31, 2006, the retained earnings of Tenaris under Luxembourg law totalled $1,173.8 million, as detailed below. (all amounts in thousands of U.S. dollars) Retained earnings at December 31, 2005 under Luxembourg law 1,171,738 Other income and expenses for the three-month period ended March 31, 2006 2,035 ----------- Retained earnings at March 31, 2006 under Luxembourg law 1,173,773 =========== 8 Business acquisitions, incorporation of subsidiaries and other significant events (a) Investment in Ternium S.A. ("Ternium") On September 9, 2005, the Company exchanged its 21.2% equity interest in Consorcio Siderurgia Amazonia Ltd. ("Amazonia") and its 24.4% equity interest in Ylopa Servicos de Consultadoria Ltda. ("Ylopa"), for 209,460,856 shares in Ternium, the company into which San Faustin N.V. (a Netherlands Antilles corporation and the controlling shareholder of Tenaris) consolidated its Latin American holdings in flat and long steel producers Siderar S.A.I.C. ("Siderar"), Sidor C.A. ("Sidor") and Hylsamex, S.A de C.V. As a result of the exchange, which was carried out based on fair values as determined by an internationally recognized investment bank engaged for this purpose, Tenaris obtained an initial ownership interest of approximately 17.9% in Ternium. Subsequently, on October 27, 2005, Usinas Siderurgicas de Minas Gerais S.A. reached an agreement with Ternium to exchange its interests in Amazonia, Ylopa and Siderar, plus additional consideration of approximately $114.1 million provided as a convertible loan, for an equity stake in Ternium. As a consequence of the additional shares issued under this transaction, Tenaris' ownership stake was reduced to 15.0% of Ternium's outstanding common stock at December 31, 2005. The effect of this transaction resulted in an increase of the Company's proportional ownership in Ternium's equity of approximately $2.7 million, which Tenaris recognized in Other Reserves in equity. 10 Tenaris S.A. Consolidated Condensed Interim Financial Statements for the three-month period ended March 31, 2006 -------------------------------------------------------------------------------- 8 Business acquisitions, incorporation of subsidiaries and other significant events (Cont'd) In addition, in August 2005 Tenaris extended to Ternium two subordinated convertible loans consisting of principal amount of $39.7 million. The principal amount of these loans at the date issue corresponded to the amount of certain distributions received from Amazonia during the second and third quarters of 2005 in connection with Ternium's participation in Amazonia's financial debt restructuring in 2003. At the date of Ternium's initial public offering ("IPO"), the loans totaled approximately $40.5 million, including accrued interest.
