Santiago, Chile, May 21, 2015 - LATAM Airlines Group S.A. and its affiliates, (“LATAM Airlines Group” or “the Company”) (NYSE: LFL / IPSA: LAN / Bovespa: LATM33), the leading airline group in Latin America, announced today it intends to offer (the “Offering”) Senior Notes (the “Notes”).

A portion of the Notes will be used to refinance the existing 9.50% Senior Guaranteed Notes due 2020 of TAM Capital 2 Inc. (the “TAM 2020 Notes”). As part of the refinancing, Citigroup Global Markets Inc. (the “Offeror”) has launched a cash tender offer for any and all of the TAM 2020 Notes and related consent solicitation to amend certain provisions in the indenture governing the TAM 2020 Notes. It is intended that the TAM 2020 Notes purchased by the Offeror in the tender offer will be exchanged by the Offeror with LATAM for a portion of the Notes sold in the Offering. LATAM intends to use the net proceeds from the Notes sold in the Offering that are not exchanged for TAM 2020 Notes to redeem any TAM 2020 Notes that are not tendered pursuant to the Tender Offer. Any remaining proceeds will be used for general corporate purposes.

The Notes will be senior unsecured obligations of LATAM. The Offering is subject to customary conditions, and there can be no assurances that the Offering will be consummated.

The Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any other jurisdiction.

The Notes will be offered only to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to non-U.S. persons outside the United States under Regulation S under the Securities Act.

This news release does not constitute an offer to sell, or a solicitation of an offer to buy, any securities. The Offering will be made only by means of the confidential offering memorandum.

The tender offer and the consent solicitation are being made only pursuant to the terms and conditions set forth in an offer to purchase and consent solicitation statement dated May 21, 2015 (the “Tender Offer and Consent Solicitation Statement”) and the related letter of transmittal and consent (the “Letter of Transmittal” and, together with the Offer and Solicitation Statement, the “Offer Documents”), which have been sent to holders of the TAM 2020 Notes. This news release is not an offer to purchase, a solicitation of an offer to sell or a solicitation of consents with respect to any securities. The tender offer is made only by, and pursuant to the terms of, the Offer Documents.

LATAM AIRLINES GROUP S.A. ANNOUNCES COMMENCEMENT OF CASH TENDER OFFER AND CONSENT SOLICITATION FOR 9.50% SENIOR GUARANTEED NOTES DUE 2020 OF TAM CAPITAL 2 INC.

Santiago, Chile, May 21, 2015 - LATAM Airlines Group S.A., its affiliates, (“LATAM Airlines Group” or the “Company”) (NYSE: LFL / IPSA: LAN / Bovespa: LATM33), TAM Capital 2 Inc. (the “Issuer”) and Citigroup Global Markets Inc. (the “Offeror” or the “Dealer Manager”) today announced the commencement of an offer by the Offeror to purchase for cash (the “Tender Offer”) any and all of the outstanding 9.50% Senior Guaranteed Notes due 2020 (the “Notes”) of the Issuer. The Tender Offer is being made by the Offeror on behalf of LATAM and the Issuer pursuant to the offer to purchase and consent solicitation statement dated May 21, 2015 (the “Tender Offer and Consent Solicitation Statement”) and the related letter of transmittal and consent (the “Letter of Transmittal” and, together with the Tender Offer and Consent Solicitation Statement, the “Offer Documents”). The principal purpose of the Tender Offer is to acquire all the outstanding Notes and the principal purpose of the Consent Solicitation (as defined below) is to eliminate substantially all of the restrictive covenants and certain events of default contained in the Indenture (as defined below).

In connection with the Tender Offer, the Issuer is also soliciting (the “Consent Solicitation”), with respect to the Notes, consents (the “Consents”) to (i) amendments to the indenture, dated October 29, 2009 (as amended and supplemented to the date hereof, the “Indenture”), among the Issuer, TAM S.A. (“TAM S.A.”) and TAM Linhas Aéreas S.A. (“TAM Linhas” and, together with TAM S.A., the “Guarantors”), as guarantors, The Bank of New York Mellon, as trustee, registrar, transfer agent and principal paying agent (the “Trustee”), and The Bank of New York Mellon (Luxembourg) S.A., as Luxembourg transfer agent (the “Luxembourg Transfer Agent”), under which the Notes were issued, which would eliminate most of the covenants, eliminate certain events of default applicable to the Notes, eliminate or amend certain other provisions contained in the Indenture and the Notes and shorten the minimum period in which the Issuer is required to give notice to holders of a redemption from 30 days to five Business Days prior to a redemption date (the “Majority Consent Amendments”) and (ii) an amendment to the Indenture, which would eliminate the “Limitations on the Company” covenant (the “Two-Thirds Consent Amendments”, and together with the Majority Consent Amendments, the “Proposed Amendments”). If the Proposed Amendments become operative, any Notes remaining outstanding after that date will no longer be entitled to the benefit of substantially all of the restrictive covenants and certain of the events of default contained in the Indenture.

The Issuer currently intends to redeem the Notes that remain outstanding following the Early Settlement Date at a cash redemption price per $1,000 principal amount of the Notes equal to $1,047.50, plus accrued and unpaid interest to the redemption date. However, the Issuer is under no obligation to do so, and may elect not to do so on that date, or at all.

The table below summarizes certain payment terms for the Notes:

Description of Notes	CUSIP/ ISIN Nos.	Outstanding Principal Amount	Tender Offer Consideration(1)(2)	Early Tender Payment(1)	Total Consideration(1)(2)
9.50% Senior Guaranteed Notes due 2020	G86665AA7, 87217AAA1 / USG86665AA70, US87217AAA16	U.S.$300,000,000	U.S.$1,023.00	U.S.$30.00	U.S.$1,053.00

The Tender Offer and Consent Solicitation will expire at 11:59 P.M., New York City time, on June 18, 2015, unless extended or earlier terminated (such date and time, including as extended or earlier terminated, the “Expiration Date”). Holders of Notes who validly tender (and do not validly withdraw) their Notes at or prior to 5:00 P.M., New York City time, on June 4, 2015, unless extended or earlier terminated (such date and time, including as extended or earlier terminated, the “Early Tender Date”), will be eligible to receive the Total Consideration (as defined below), which includes the Early Tender Payment (as defined below), plus accrued interest to the date of payment. Holders of Notes who validly tender Notes after the Early Tender Date but at or prior to the Expiration Date in the manner described herein will not be eligible to receive the Early Tender Payment and will therefore only be eligible to receive the Tender Offer Consideration (as defined below), plus accrued interest to the date of payment. Notes that have been validly tendered pursuant to the Tender Offer may be validly withdrawn prior to the Early Tender Date but not thereafter except as may be required by applicable law.

The “Total Consideration” for each U.S.$1,000 principal amount of Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Date and accepted for purchase pursuant to the Tender Offer will be U.S.$1,053.00, which includes an early tender payment equal to U.S.$30.00 (the “Early Tender Payment”), and Holders of such Notes will be eligible to receive the Total Consideration within three business days following the Early Tender Date (the “Early Settlement Date”). Holders of Notes who validly tender Notes after the Early Tender Date but at or prior to the Expiration Date and whose Notes are accepted for purchase will not be entitled to receive the Early Tender Payment and will therefore be entitled to receive, for each U.S.$1,000 principal amount of Notes accepted for purchase, U.S.$1,023.00 (the “Tender Offer Consideration”).

The Offeror intends to accept for purchase on the settlement date that is expected to be within three business days following the Expiration Date or as promptly as practicable thereafter (the “Final Settlement Date”), all Notes validly tendered (and not validly withdrawn) at or prior to the Expiration Date.

Adoption of the Majority Consent Amendments requires the written consent of the Holders of at least a majority of the principal amount of the outstanding Notes (the “Majority Consents”) and adoption of the Two-Thirds Consent Amendments requires the consent of not less than 66 2/3% of the aggregate principal amount of the Notes (the “Two-Thirds Consent” and, together with the Majority Consents, the “Requisite Consents”). The Offeror will only accept Notes for purchase if Consents representing at least a majority of the principal amount of the outstanding Notes to authorize the Proposed Amendments are validly delivered and not validly revoked. Assuming that Consents representing at least a majority of the principal amount of the outstanding Notes (excluding any Notes owned by the Issuer or its affiliates) are validly delivered and not validly revoked, the Issuer, the Guarantors and the Trustee will execute a supplemental indenture with respect to the Indenture (the “Supplemental Indenture”) providing for the Proposed Amendments. The Supplemental Indenture will become effective upon its execution and delivery by the Issuer, the Guarantors and the Trustee, but will provide that the Proposed Amendments will not become operative until the Offeror accepts for purchase in the Tender Offer at least a majority (in the case of the Majority Consent Amendments), or not less than 66 2/3% (in the case of the Two-Thirds Consent Amendments), in principal amount of the outstanding Notes (excluding any Notes owned by the Issuer or its affiliates), and the Exchange (as defined below) is consummated.

Holders may not tender their Notes without delivering their Consents to the Proposed Amendments and to the execution and delivery of the Supplemental Indenture pursuant to the Consent Solicitation and may not deliver Consents to the Proposed Amendments and the execution and delivery of the Supplemental Indenture without tendering their Notes pursuant to the Tender Offer. Holders that validly tender their Notes pursuant to the Tender Offer will be considered to have validly delivered their Consents.

The Issuer and LATAM have consented to the Offeror making the Tender Offer and the Consent Solicitation. It is intended that the Notes purchased by the Offeror in the Tender Offer will be exchanged by the Offeror with LATAM for certain new notes (the “Exchange”) issued in a new offering by LATAM (the “New Offering”).

The obligation of the Offeror to accept for purchase, and to pay for, Notes validly tendered pursuant to the Tender Offer is subject to, and conditioned upon, the satisfaction or waiver of certain conditions as set forth in the Offer Documents, in the sole discretion of the Offeror, including consummation of the New Offering in terms satisfactory to LATAM and receipt by the Offeror of valid tender (that are not withdrawn) of a majority of the outstanding Notes.
