is also an important provider of midstream services, which consist mainly of gas treatment and removal

of impurities from the natural gas stream and gas compression, as well as other services relating to

pipeline construction, operation and maintenance. TGS was organized in Argentina on November 24,

TGS is a foreign private issuer within the meaning of Rule 405 under the Securities Act of 1933 (the

"Securities Act") and Rule 3b-4 under the Exchange Act. TGS's Class B Shares are listed on the

Mercado de Valores de Buenos Aires, S.A.(the "MERVA~")and trade under the ticker symbol "TGSU2"

and its ADSs and the Class B Shares underlying them are registered under the Exchange Act and listed

on The New York Stock Exchange under the ticker symbol "TGS".

Background

The Argentine Offer

In Argentina, the Offerors are offering to purchase up to 194,651,345 outstanding Class B Shares (the

"Argentine Offer') held by any holder, wherever resident, in cash at a price of Ps. 18.39 per Class B

Share, which is the same price being offered in the U.S. Offer (before adjustments to reflect the five-toone ratio of Class B Shares to ADSs and foreign currency conversion). The Argentine Offer is being

conducted in accordance with Argentine Law No. 26,831 (the "Argentine Capital Markets Law") and

General Resolution No. 622/2013, issued by the Argentine securities commission, the Argentine

Comisibn Nacional de Valores (the "CNV"), as amended (the "CNV Regulations"). The Argentine Offer

is required in Argentina as a mandatory offer pursuant to Article 87(and related articles} of the Argentine

Capital Markets Law and Article 10 of Section II of Chapter II of Title 111 of the CNV Regulations.

The U.S. Offer

Due to certain irreconcilable differences, as set forth below, between law in Argentina and the U.S., such

as differing withdrawal rights for tendering security holders, it was not possible to structure a single

tender o~Fer for both Class B Shares and ADSs that would have been compliant with both Argentine law

and Regulation 14D under the Exchange Act.

As a result, concurrently with the Argentine Offer, the Offerors are offering to purchase (the "U.S. Offer'

and, together with the Argentine Offer, the "Offers"):

(i}

Class B Shares for Ps. 18.39 per Class B Share from shareholders that are resident in the U.S.

("U.S. Holders")(the same price being offered for Class B Shares in the Argentine Offer); and

Page 2 of 6

Li n klate rs

(ii)

ADSs for Ps. 91.95 per ADS (five times the per Ciass B Share price in the Argentine Offer)from

all holders, wherever located.

U.S. Holders tendering their Class B Shares and U.S. Holders or non-U.S. Holders tendering ADSs in

the U.S. Offer and whose Class B Shares orADSs are accepted by the Offerors will receive payment in

U.S. dollars, in each case based on the Ps./U.S. dollar selling exchange rate reported by Banco de la

Naci6n Argentina at the close of business on the Argentine business day prior to the expiration date of

the U.S. Offer,

The U.S. Offer is on the same terms as the Argentine Offer, except:

The U.S. Offer is for ADSs held by any holder wherever resident and Class B Shares

held by U.S. Holders. The Argentine Offer is for Class B Shares held by any holder,

wherever resident.

The U.S. Offer will allow the withdrawal of all tendered Class B Shares and ADSs until

the Expiration Time (as defined below) of the U.S. Offer. Argentine law does not allow

withdrawal of tendered Class B Shares.

Class B shareholders and ADS holders who tender in the U.S. Offer will receive U.S.

dollars. Class B shareholders who tender in the Argentine Offer will receive Argentine

pesos.

The U.S. Offer was commenced on December 30, 2016. The Argentine Offer was commenced on

February 6, 2017. Unless extended, the U.S. Offer will expire at 11:00 a.m., New York City time on March

15, 2017(the "Expiration Time"). The Argentine Offer will expire concurrently with the U.S. Offer at 1:00

p.m. Buenos Aires time on March 15, 2017.

Qualification for Tier II Relief

In conducting the Offers on the terms described in this letter, the Offerors are relying on Rule 14d-1(d)

under the Exchange Act, which provides exemptive relief from otherwise applicable rules to persons

conducting a tender offer under certain conditions. In order for the Offerors to qualify for exemptive relief

under Rule 14d-1(d)("Tier II Relief'), (i) TGS must be a foreign private issuer,' (ii) TGS must not be,

and the Offerors must believe, based on publicly available information, that it is not, an investment

company registered or required to be registered under the Investment Company Act of 1940 and (iii)

shareholders that are resident in the U.S.("U.S. Holders") must not hold more than forty percent (40°/a)

of the class of securities sought in the Offers (TGS Class B Shares, including those represented by

ADSs).

In accordance with Instruction 2 to Rule 14d-1(d), in connection with the U.S. Offer and Argentine Offer,

the Offerors undertook an assessment of the level of ownership of Class B Shares and ADSs in the

Uni#ed States to determine the applicability of the U.S tender offer rules to the Offers. To this end, the

Offerors obtained a shareholder list from Caja de Valores S.A. as of May 31, 2016. An analysis of this

Based on TGS's most recent Form 20-F, filed with EDGAR on May 2, 2016, TGS holds itself out to be a foreign private issuer.

Furthermore, TGS is a corporation organized under the laws of Argentina and, to the Offerors' knowledge of TGS: (i) the

majority of TGS' executive o~cers and directors are not U.S. citizens or residents; (ii) fifty percent (50%) or more of TGS'

assets ars located outside the U.S.; and (iii) TGS' business is principally administered outside the U.S.

Linklaters

information reveals that as of May 31, 2016, such date within 60 days prior to the announcement of the

Argentine Offer on July 27, 2016, of the 389,302,689 Class B Shares outstanding, shareholders with

U.S. addresses held approximately 160,Q91,995 Ciass B Shares, including Class B Shares underlying

ADSs.

Based on these share totals, shareholders with U.S. addresses held approximately 41.1 percent(41.1%)

of the total number of Class B Shares outstanding on May 31, 2016. The Offerors also examined the

beneficial ownership of shares held by brokers, dealers, banks and other nominees in the U.S. and

Argentina. After such reasonable inquiry, the Offerors determined that approximately 28.4 percent

(28.4%)of outstanding ordinary shares (including ADSs) were held by U.S. Holders.

Based on the foregoing, the Offerors believe that they qualify for Tier it Relief.

Discussion

Relevant Rules

Article 70 (Distribution and Proration Rules), Section VII, Chapter 11, Title III of the CNV Regulations

Article 70 (Distribution and Proration Rules), Section VII, Chapter II, Title III of the CNV Regulations

{"Article 70") governs the proration method applicable to the Argentine Offer in the event that proration

of tendered securities is required due to the number of securities being tendered in the Offers exceeding

194,651,345 Class B Shares (including Class B Shares represented byADSs}. Article 70 states:

"a) Linear allocation: The allocation will be started by allocating an equal number of

securities to each accepting participant. Such number of allocated securities will be the

number that results from dividing twenty-five percent(25%) of the total of the offer by

the number of acceptances received.

b) All tenders for a number of securities lower than the number resulting from the

arithmetic operation described in paragraph a) above will be fully accepted for

purchase.

c) All acceptances made, directly or indirectly by the same legal or natural person will

be deemed a single acceptance.

d) Excess distribution: Any remaining securities not accepted for purchase as stated

above will be distributed proportionally to the number of securities included in each

acceptance."

As requested by the Commission, an opinion of the Offerors' Argentine counsel, Marval, O'Farrell &

Mairal, to that effect is attached to this letter as Annex A.

Rule 14d-1(d)(2)(ii) under the Exchange Act

Rule 14d-1(d)(2)(ii) under the Exchange Act permits a bidder conducting a Tier 11 tender offer to separate

an offer into multiple offers, one offer made to U.S. Holders and one ar more offers to nan-U.S. Holders,

provided that the U.S. offer must be made on terms at least as favorable as those offered to any other

holder of the same class of securities that is the subject of the tender offers.

Linklaters

Exchange Act Section 14(d)(6) and Rule 14d-8 under the Exchange Act

Exchange Act Section 14(d)(6) provides that where any person makes a tender offer, or request or

invitation for tenders, for less than ail the outstanding equity securities of a class, and where a greater

number of securities is deposited pursuant thereto within ten days after copies of the offeror request or

invitation are first published or sent or given to security holders than such person is bound or willing to

take up and pay for, the securities taken up shall be taken up as nearly as may be pro rata, disregarding

fractions, according to the number of securities deposited by each depositor.

Rule 14d-8 under the Exchange Act provides that if a person makes a tender offer for less than all of

the outstanding securities of a class, and a greater number of securities are deposited pursuant thereto

than such person is bound or willing to take up and pay for, the securities taken up and paid for shall be

taken up and paid for as nearly as may be pro rata, disregarding fractions, according to the number of

securities deposited by each depositor during the period the offer remains open.

Analysis

In order for the Argentine Offer to be compliant with Argentine law, proration under the Argentine Offer

must follow the linear allocation formula specified by Article 70. Under this linear allocation formula, a

number of securities equal to twenty-five percent(25%) of the total number of securities included in the

offer divided by the number of acceptances received, is first allocated for purchase from each

participating holder (the "Initial Allocation"). Any tender for a number of securities less than or equal to

such Initial Allocation will be fully accepted for purchase. Following the Initial Allocation, Article 70

provides that the remaining securities are to be distributed proportionally to the number of securities

included in each acceptance (the "Excess Distribution"). Holders who had their tender fully accepted

in the Initial Allocation do not participate in the Excess Distribution. As a result of the Initial Allocation,

holders tendering a relatively smaller number of Class B Shares will have a greater percentage of their

tendered Class B Shares accepted for purchase than Class B shareholders who tender a relatively

larger number of Class B Shares.

Rule 14d-1(d)(2)(ii) under the Exchange Act requires that the U.S. Offer be on terms that are at least as

favorable as those offered under the Argentine Offer. In order to comply with Rule 14d-1(d)(2)(ii), the

Offerors must provide for proration in the U.S. Offer that is at least as favorable to tendering holders as

the proration terms provided for in the Argentine Offer. As such, failure to provide the Initial Allocation

required under Article 70 in the U.S. Offer could be considered a violation of Rule 14d-1(d)(2)(ii), as the

Initial Allocation is a term in the Argentine Offer that may be more favorable to certain tendering holders

of Class B Shares.

Section 14(d)(6) and Rine 14d-8 under the Exchange Act, however, require that in the case of a tender

offer for less than all of the outstanding securities of a class where a greater number of securities are

tendered than the offeror is willing to accept, the securities taken up must be paid for pro rata according

to the number of securities deposited by each depositor during the offer period. Providing the Initial

Allocation required under Article 70 in the U.S. Offer therefore could be considered a violation of Section

14(d)(6) and Rule 14d-8, as by following the proration procedure mandated by Article 70 with respect to

the Initial Allocation, the Offerors may not be considered to be distributing securities to all tendering

holders pro rata according to the number of securities tendered.

Page 5 of 6

Linklaters

Additionally, because the proration procedures mandated by Article 70 may allow holders tendering a

relatively smaller number of shares to have a greater percentage of their tendered securities accepted

for purchase than the percentage accepted from holders tendering a relatively larger number of shares,

following the Article 70 proration procedures in the U.S. Offer could be considered a violation of the "all

holders" rule in Rule 14d-10(a)(2) under the Exchange Act, which requires that the consideration paid

to any security holder for securities tendered in the tender offer is the highest consideration paid to any

other security holder for securities tendered in the tender offer.

In discussions between the CNV and the Offerors, the CNV has made it clear to the Offerors that in its

view if the Offers (or either of them) did not follow the proration mechanics described in Article 70, the

Offers would be non-compliant with Argentine rules. On February 6, 2017, the Offerors met with the

CNV who confirmed that a request for exemptive relief from application of the pro-ration mechanics

described in Article 70 would be denied by the CNV. As a consequence, the Offerors are seeking the

exemptive relief set forth herein. Therefore, we respectfully request exemptive relief under Section

14(d)(6), Rule 14d-8 and Rule 14d-10(a)(2) to permit the Offerors, in the event proration is required in

the U.S. Offer, to calculate such proration in accordance with the formula required by Article 70.

Requested Exemptive Relief

For the reasons described above, we respectfully request exemptive relief from provisions of Section

14(d)(6), Rule 14d-8 and Rule 14d-10(a)(2) under the Exchange Act as discussed in this letter. We note

that the relief sought is consistent with the position previously taken by the Staff with respect to

Advanced Semiconductor Engineering, Inc.'s tender offer for shares of Siliconware Precision Industries

Co., Ltd. to permit proration rules required by the subject company's home jurisdiction (see Siliconware

Precision Industries Co., Ltd. (September 17, 2015) and Siliconware Precision Industries Co., Ltd.

(December 28, 2015)).

If you have any questions or comments or need additional information, please contact the undersigned

at (212) 903-9424. If, for any reason, it does not appear that the Staff will be able to concur with the

Offerors' position as stated in this letter, we would appreciate the opportunity to discuss this matter with

the Staff prior to the issuance of its formal response.

Yours sincerely,
