Filing Type: Form 6-K (Report of Foreign Issuer)
Reporting Period: Three months ended March 31, 2008
Business Overview: TGS operates a natural gas pipeline system in Argentina and produces/commercializes Natural Gas Liquids (NGL) at the Cerri Complex.

Key Financial Metrics (Three Months Ended March 31, 2008)

Segment Performance:

• Gas Transportation: Revenues of Ps. 127.3 million (27% of total). Slight increase of Ps. 1.8 million due to new firm contracts.
• NGL Production & Commercialization: Revenues of Ps. 320.4 million (69% of total). Significant increase of Ps. 137.9 million driven by higher international reference prices.
• Other Services: Revenues of Ps. 16.4 million. Decrease of Ps. 15.1 million due to lower construction service sales.

Liquidity & Debt:

• Liquidity Ratio: 2.46 (Current Assets / Current Liabilities).
• Debt Profile: Total loans approx. Ps. 1,631.6 million. Includes Ps. 1,584 million in non-current notes (US$ 500 million issuance in 2007) and Ps. 47.6 million in current loans.
• Dividends: Shareholders approved a Ps. 32 million dividend payment in April 2008.

Material Changes vs. Prior Period

• Revenue Growth: Net revenues increased by Ps. 124.6 million (36.7%) year-over-year, primarily driven by the NGL segment.
• Profitability: Net income rose by Ps. 14.3 million (21.5%) to Ps. 80.7 million. Operating income increased by Ps. 32.1 million.
• Cost Increases: Costs of sales and administrative expenses rose by Ps. 92.5 million. This was driven by a Ps. 47.5 million increase in NGL production costs and a Ps. 36.0 million increase in export taxes (rates increased from 20% to 25% for propane/butane and 5% to 45% for gasoline).
• Financial Expenses: Net financial expense decreased by Ps. 9.6 million (improvement) due to reduced interest expenses (approx. 20% reduction in financial indebtedness) and lower foreign exchange losses.
• Other Income: "Other (expense)/income, net" swung from a Ps. 15.4 million gain in 2007 to a Ps. 3.5 million expense in 2008. This was largely due to the partial reversal of a Ps. 15.5 million allowance related to a turnover tax claim, which was confirmed by the Tax Court in 2007 but not repeated in 2008.

Outlook, Risks, and Contingencies

Management Outlook:

• Focus on re-composing economic value through prepayment schemes from clients.
• Strategy to develop alternative expansion mechanisms and logistics solutions for the NGL segment.
• Continued emphasis on operational efficiency and new technologies.

Regulatory Risks & Tariff Renegotiation:

• Tariff "Pesification": Since 2002, tariffs have been fixed at US$1 = Ps.1, eliminating dollar-indexation. The Emergency Law expires December 31, 2008.
• Renegotiation Stalemate: Ongoing negotiations with UNIREN (Unit for Renegotiation and Assessment of Utilities Contracts) regarding license terms and tariff adjustments have seen no significant progress as of the filing date.
• Gas Electronic Market (MEG): Future revenues from interruptible transportation may be impacted by the creation of the MEG, which requires offering non-allocated capacity to the market.

Legal and Tax Contingencies:

• Turnover Tax (Buenos Aires): TGS maintains a provision of Ps. 16.9 million regarding a dispute over NGL sales tax exemptions. A formal assessment of Ps. 3.6 million was received in Feb 2008.
• Turnover Tax (Santa Cruz/Río Negro): Provision of Ps. 21.2 million recorded for potential tax liabilities on gas used as fuel. Management believes these costs could be recovered via tariff increases.
• GdE Lawsuit: Net provision of Ps. 12.5 million remains for a Supreme Court judgment regarding compressor plant costs, partially offset by pipeline expansion works.
• Bank of America Arbitration: Claim filed for US$ 9 million regarding a cancelled fund transfer.
• BCRA Proceedings: Summary proceedings initiated by the Central Bank regarding late foreign currency settlements (approx. US$ 14.7 million); no provision recorded as management contests the violation.

Investor Verification Checklist

• Tariff Renegotiation Status: Verify the current status of negotiations with UNIREN and the likelihood of tariff adjustments before the Emergency Law expires in Dec 2008.
• Export Tax Regime: Confirm the impact of the variable export tax regime (minimum 45%) on future NGL margins, given the segment's reliance on international prices.
• Asset Valuation: Review the auditor's qualified opinion regarding the recoverable value of non-current assets related to the regulated business, given the uncertainty of future cash flows.
• Debt Covenants: Monitor compliance with debt covenants (coverage ratio > 2.0:1, debt ratio < 3.75:1) which restrict dividend payments and new debt.
• Legal Provisions: Assess the potential for additional provisions related to the ongoing tax disputes in Buenos Aires, Santa Cruz, and Río Negro.
