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"), a Luxembourg corporation (societe anonyme
holding), was incorporated on December 17, 2001 as a holding company for
investments in steel pipe manufacturing and distributing operations. The Company
holds, either directly or indirectly, controlling interests in various
subsidiaries. References in these financial statements to "Tenaris" refer to
Tenaris S.A. and its consolidated subsidiaries. A list of the Company's
subsidiaries is included in Note 32 to the audited Consolidated Financial
Statements for the year ended December 31, 2006 and updated in Note 9 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, 2006. These consolidated condensed
interim financial statements should be read in conjunction with the audited
Consolidated Financial Statements for the year ended December 31, 2006, which
have been prepared in accordance with International Financial Reporting
Standards ("IFRS").

Certain comparative amounts have been reclassified to conform to changes in
presentation in the current year.

In May 2007, Tenaris acquired Hydril Company ("Hydril"), a company engaged in
engineering, manufacturing and selling of premium connections and pressure
control products for oil and gas drilling production. Hydril's premium
connections business was allocated to the Tubes segment and a new segment was
created -Pressure Control- for Hydril's pressure control business.

The Tubes segment includes the operations that consist in the production and
selling of both seamless and welded steel tubular products and related services
mainly for energy and industrial applications.

The Projects segment includes the operations that consist in the production and
selling of welded steel pipe products mainly used in the construction of major
pipeline projects.

The Pressure Control segment includes the operations that consist in the
production and selling of products such as blowout preventers and subsea control
systems and related products used in oil and gas drilling applications.

The Others segment includes the operations that consist in the production and
selling of sucker rods, welded steel pipes for electric conduits, industrial
equipment and raw materials, such as hot briquetted iron, or HBI, that exceed
Tenaris's internal requirements.

Corporate general and administrative expenses have been allocated to the Tubes
segment.

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, since the functional currency of
some subsidiaries is its respective local currency, some financial gains
(losses) arising from intercompany transactions are generated. These are
included in the consolidated condensed interim income statement under Other
financial results.

These consolidated condensed interim financial statements were approved for
issue by Tenaris's Board of Directors on November 7, 2007.

8        Contingencies, commitments and restrictions to the distribution
         of profits

This note should be read in conjunction with Note 26 to the Company's audited
Consolidated Financial Statements for the year ended December 31, 2006.
Significant changes or events since the date of such financial statements are
the following:

Asbestos-related Litigation

In addition to the previously known 12 civil proceedings for work-related
injuries arising from the use of asbestos in its manufacturing processes during
the period from 1960 to 1980, 40 asbestos-related out-of-court claims and 1
civil party claim, 2 new asbestos-related out-of-court claims have been notified
to Tenaris's subsidiary Dalmine during third quarter 2007; while 1 claim was
adjudicated, dismissed or settled. Accordingly, as of September 30, 2007, the
total asbestos-related claims pending against Dalmine are 54 (of which, 3 are
covered by insurance). Aggregate settlement costs to date are Euro 5.1 million.
Dalmine estimates that its potential liability in connection with the claims
above that are not yet settled is approximately Euro 17.7 million ($25.1
million) of which Euro 8.7 million ($12.3 million) relate to the claims and
proceedings notified to Dalmine during 2007.

Accruals for Dalmine's potential liability are based on the average of the
amounts paid by Dalmine for asbestos-related claims plus an additional amount
related to some reimbursements requested by the social security authority. The
maximum potential liability is not determinable as in some cases the requests
for damages do not specify amounts, and are instead to be determined by the
court. The timing of payment of the amounts claimed is not presently
determinable.

Maverick litigation

On December 11, 2006, The Bank of New York ("BNY"), as trustee for the holders
of Tenaris's subsidiary Maverick Tube Corporation ("Maverick") 2004 4%
Convertible Senior Subordinated Notes due 2033 issued pursuant to an Indenture
between Maverick and BNY ("Noteholders"), filed a complaint against Maverick and
Tenaris in the United States District Court for the Southern District of New
York. The complaint alleges that Tenaris's acquisition of Maverick triggered the
"Public Acquirer Change of Control" provision of Indenture, asserting breach of
contract claim against Maverick for refusing to deliver the consideration
specified in the Public Acquirer Change of Control provision of the Indenture to
Noteholders who entered their notes for such consideration. This complaint seeks
a declaratory judgement that Tenaris's acquisition of Maverick was a Public
Acquirer Change of Control under the Indenture, and asserts claims for tortuous
interference with contract and unjust enrichment against Tenaris. Defendants
filed a motion to dismiss the complaint, or in the alternative, for summary
judgment on March 13, 2007. Plaintiff filed a motion for partial summary
judgment on the same date. Briefing on the motions has been completed.

Tenaris believes that these claims are without merit. Accordingly, no provision
was recorded in these financial statements. Were plaintiff to prevail, Tenaris
estimates that the recovery would be approximately $50 million.

European Commission Fine

On January 25, 2007, the Court of Justice of the European Commission confirmed
the December 8, 1998 decision by the European Commission to fine eight
international steel pipe manufacturers, including Dalmine, for violation of
European competition laws. Pursuant to the Court's decision, Dalmine is required
to pay a fine of Euro 10.1 million plus interest ($13.3 million plus interest).
Since the infringements for which the fine was imposed took place prior to the
acquisition of Dalmine by Tenaris in 1996, Dalmine's former owner, has
reimbursed Dalmine for 84.1% of the fine. The remaining 15.9% of the fine has
been paid out in 2007 of the provision that Dalmine established in 1999 for such
proceeding.

Customer Claim

A lawsuit was filed on September 6, 2007 against Tenaris's subsidiary Maverick
Tube Corporation ("Maverick"), alleging negligence, gross negligence and
intentional acts characterized as fraudulent inducement concerning allegedly
defective well casing and the complete loss of one natural gas production well.
Plaintiff seeks compensatory and punitive damages of $25 million in its original
petition. On September 10, 2007, this lawsuit was tendered to Maverick's insurer
and on September 26, 2007, Maverick received the insurer's agreement to provide
a defense. No provision was recorded on these financial statements.

Employee retention and long term incentive program

On January 1, 2007 Tenaris adopted an employee retention and long term incentive
program. Pursuant to this program, certain senior executives will be granted a
number of units equivalent in value to the equity book value per share
(excluding minority interest). The units will be vested over a period of four
years and Tenaris will redeem vested units following a period of ten years from
the grant date, or when the employee ceases employment, at the equity book value
per share at the time of payment. Beneficiaries will also receive a cash amount
per unit equivalent to the dividend paid per share whenever the Company pays a
cash dividend to its shareholders.

Compensation under this program is not expected to exceed 35% in average of the
total annual compensation of the beneficiaries.

The total value of the units granted to date under the program, considering the
number of units and the book value per share as of September 30, 2007, is $7.6
million. As of September 30, 2007, Tenaris has recorded a total liability of
$14.3 million taking into account expected industry growth and discount rate.

Commitments

Set forth is a description of Tenaris's main outstanding commitments:

     o    A Tenaris company is a party to a ten year raw material purchase
          contract with QIT, under which it committed to purchase steel bars,
          with deliveries starting in July 2007. The estimated aggregate amount
          of the contract at current prices is approximately $299 million.

     o    A Tenaris company is a party to a five year contract with Nucor
          Corporation, under which it committed to purchase from Nucor steel
          coils, with deliveries starting in January 2007. Prices are adjusted
          quarterly in accordance with market conditions and the estimated
          aggregate amount of the contract at current prices is approximately
          $1,053 million.

     o    A Tenaris company is a party to a steel supply agreement with IPSCO,
          under which it is committed to purchase steel until 2011. Prices are
          adjusted monthly or quarterly and the estimated aggregate amount of
          the contract at current prices is approximately $123 million. Each
          party may terminate this agreement at any time upon a one-year notice.

     o    A Tenaris company is a party to transportation capacity agreements
          with Transportadora de Gas del Norte S.A. for capacity of 1,000,000
          cubic meters per day until 2017. As of September 30, 2007, the
          outstanding value of this commitment was approximately $55.4 million.
          The Tenaris company also expects to obtain additional gas
          transportation capacity of 315,000 cubic meters per day until 2027.
          This commitment is subject to the enlargement of certain pipelines in
          Argentina.

     o    A Tenaris company is party to a contract with Siderar for the supply
          of steam generated at the power generation facility owned by Tenaris
          in San Nicolas. Under this contract, the Tenaris company is required
          to provide 250 tn/hour of steam, and Siderar has the obligation to
          take or pay this volume. This outsourcing contract is due to terminate
          in 2018.

reserve are not required under Luxembourg law. Dividends may not be paid out of
the legal reserve.

The Company may pay dividends to the extent, among other conditions, that it has

9        Business acquisitions, incorporation of subsidiaries and other
         significant events

(a) Acquisition of Hydril Company

On May 7, 2007, Tenaris paid $2.0 billion to acquire Hydril, a North American
manufacturer of premium connections and pressure control products for the oil
and gas industry. To finance the acquisition, Tenaris entered into syndicated
loans in the amount of $2.0 billion, of which $0.5 billion were used to
refinance an existing loan in the Company. The balance of the acquisition cost
was paid out of cash on hand. Of the loan amount, $1.7 billion was allocated to
the Company and the balance to Hydril.

The main covenants on these loan agreements are limitations on liens and
encumbrances, restrictions on investments and capital expenditures, limitations
on the sale of certain assets and compliance with financial ratios (e.g.,
leverage ratio and interest coverage ratio in Hydril's syndicated loan
agreement, and leverage ratio and debt service coverage ratio in the Company's
syndicated loan agreement). In addition, the Company's syndicated loan agreement
is secured with a pledge of 100% of Hydril's shares; immediately upon each
payment or prepayment under this agreement, the number of shares subject to the
pledge shall be reduced proportionally, and the pledge will be completely
released immediately after the aggregate outstanding principal amount of the
loan is less than or equal to $600 million. The Company is allowed to make
payments such as dividends, repurchase or redemption of shares up to the greater
of $475 million or 25% of the consolidated operating profit for the previous
fiscal year; once the outstanding amount of this facility does not exceed $1,000
million, no such restrictions will apply.

9        Business acquisitions, incorporation of subsidiaries and other
         significant events (Cont'd)

(a) Acquisition of Hydril Company (Cont'd)

On October 29, 2007, Tenaris gave notice to the administrative agent under its
syndicated loan agreement entered into to finance the acquisition of Hydril, of
its commitment to prepay, on November 8, 2007, loans there under in a principal
amount of $0.7 billion plus accrued interest thereon to such date. Immediately
upon such prepayment, approximately 64% of Hydril shares shall be released from
the pledge granted to secure the obligations under the loan agreement, and all
dividend restrictions under the syndicated loan agreement will cease to apply.

Tenaris began consolidating Hydril's balance sheet and results of operations
since May, 2007.

Pro forma data including acquisitions for the nine-month period ended
September 30, 2007

Had the Hydril transaction been consummated on January 1, 2007, then Tenaris's
unaudited pro forma net sales and net income for the nine-month period ended
September 30, 2007 would have been approximately $7.7 billion and $1.5 billion,
respectively. These pro forma results were prepared based on public information
and unaudited accounting records maintained under US GAAP prior to such
acquisition and adjusted by depreciation and amortization of tangible and
intangible assets and interest expense of the borrowing incurred for the
acquisition as described in Note 9(a) considering the repayment stated in Note
9(b). Carrying amounts of assets, liabilities and contingent liabilities in
Hydril's books, determined in accordance with IFRS immediately before the
combination are not disclosed separately, as Hydril did not report financial
information under IFRS.

(b) Acquisition of Maverick

On October 5, 2006, Tenaris completed its acquisition of Maverick, pursuant to
which, Maverick merged with and into a wholly owned subsidiary of Tenaris. On
that date, Tenaris paid $65 per share in cash for each issued and outstanding
share of Maverick's common stock. The value of the transaction at the
acquisition date was $3,160 million, including Maverick's financial debt.
Tenaris began consolidating Maverick's balance sheet and results of operations
in the fourth quarter of 2006.

A Tenaris syndicated loan facility in an aggregate principal amount of $500
million, which had been incurred in connection with the Maverick acquisition,
was prepaid in its entirety in May 2007, and upon such prepayment the previous
pledge on Maverick's shares was released. During this quarter, Tenaris's
subsidiary Algoma Tubes syndicated loan facility in an aggregate amount of $100
