sell its shares, either spontaneously or because it has received an offer from a third party, to grant a right of first refusal (hereinafter the Right of First Refusal) to purchase such shares to the other shareholders who are parties to
the Shareholders Agreement



THEREFORE, the Parties agree
to the following:



ARTICLE FIRST

JOINT ACTION



1.1 Joint Action.



(a) The Parties agree to exercise control of Lan Chile jointly, thus ensuring a majority of votes at shareholders meeting and at board meetings. For these
purposes, the



2



---

parties undertake to act in coordination and by mutual consent in all matters and decisions relating to the management and administration of Lan Chile,
whether such matters and decisions must be decided by the shareholders meeting or by the companys board of directors.



(b) If the Parties are unable to agree on how to act, they undertake to respect the mandate granted to the third party indicated in Section 1.2(b) below
in order not to hinder the management and administration of Lan Chile. This obligation of respect for the mandate will be ongoing and permanent as long as there is a disagreement among the parties until this Joint Action Agreement is terminated in
the manner stipulated in Article Fourth below.



1.2
Shareholders Meetings.



(a) The Parties shall appoint a
common representative to attend shareholders meetings and vote the Committed Shares in terms agreed upon by the Parties. The appointment of the common representative shall be made prior to each shareholders meeting through the grant of the
respective powers of attorney in the terms indicated in Articles 63 and 64 of the Companies Regulations.



(b) If the Parties do not agree on how to vote the Committed Shares five days prior to a shareholders meeting, Mr. Sergio Urrejola Monckeberg shall be
appointed common representative and if he is unable or unwilling to accept the position, Mr. Juan Claro González; and if he is unable or unwilling to accept the position, Mr. Arturo Yrarrázaval Covarrubias; and if he is unable or
unwilling to accept the position, Mr. Felipe Larraín Bascuñan; and if he is unable or unwilling to accept the position, Mr. Enrique Barros Bourie. Once the common representative that has been appointed has accepted the position, the
Parties shall grant the respective powers of attorney thereto in the terms indicated in Articles 63 and 64 of the Companies Regulations. The common representative thus appointed shall vote the Committed Shares as he deems pertinent.



(c) Notwithstanding the stipulations in Section 1.2(b) above, if the
shareholders meeting must decide on the election of directors and there is no agreement among the Parties on the five directors to be elected with the Committed Shares, each Party shall have the right to propose two directors and to instruct the
common representative to vote the



3



---

Committed Shares in order to elect the candidates thereof. The fifth director will be decided by the common representative and such appointment shall fall
upon his person or upon any of the following independent third parties: Sergio Urrejola Monckeberg, Juan Claro González, Arturo Yrarrázaval Covarrubias, Felipe Larraín Bascuñán or Enrique Barros Bourie. For these
purposes, the Parties shall grant the common representative the respective powers of attorney in the terms indicated in Articles 63 and 64 of the Companies Regulations.



1.3 Board of Directors.



(a) The Parties shall endeavor for the directors elected with the Committed Shares to always act together and vote for resolutions of the board so as to
constitute the majority necessary to adopt them. For these purposes, the Parties shall ensure that the meeting agenda is distributed sufficiently in advance in order to allow them to analyze and agree upon each item contained in such agenda prior to
the board meeting and to undertake to recommend and persuade such directors how to vote.



(b) If the Parties do not reach an agreement on the items contained in the agenda five days prior to a board meeting, the Parties shall resort to the common representative indicated in Section 1.2 (b) above and
undertake to recommend and persuade the directors elected with the Committed Shares to vote in the terms decided by such common representative.



(c) Notwithstanding the stipulations in Sections 1.3(a) and (b) above, the Parties shall endeavor to meet as soon as possible when there are urgent
matters or items arising at the same board meeting on which a decision cannot be postponed without seriously affecting the management and administration of Lan Chile and, if necessary, to cause the directors elected with the Committed Shares to
leave the meeting temporarily in order for the Parties to analyze and agree on how to proceed and recommend and persuade such directors how to vote. If circumstances warrant, the Parties shall resort to the common representative indicated in Section
1.2(b) above and they undertake to recommend and persuade the directors elected with the Committed Shares to vote in the terms decided by such common representative.



4



---

(d) If the mechanism established in Section 1.2(c) above must be used for the election of the board of
directors, each Party undertakes to recommend and persuade the directors nominated thereby to vote in the terms decided by the director nominated by the common representative.



(e) If at any time any of the directors elected with the Committed Shares votes against the agreements of the Parties, the
Parties shall endeavor to secure the voluntary resignation thereof and appointment of his replacement by the board in office for the period until the next regular shareholders meeting in the terms of Article 32 of the Companies Law. If it were
impossible to secure the voluntary resignation of the dissident director or to ensure the appointment of the replacement thereof in the aforesaid terms, any of the Parties may require that the board of directors convene a special shareholders
meeting in order to revoke the entire board of directors in office and elect a new one, and thus be able to replace the dissident director. Upon exercising this right, the Parties shall vote in favor of the revocation and proceed with the renewal of
the board of directors using the mechanisms established in Section 1.2 above.



(f) If, in the case indicated in Section 1.3 (e) above, the dissident director has been proposed by one of the Parties, such Party shall be liable for securing the voluntary resignation thereof and if it cannot, for
requiring that the board convene the respective special shareholders meeting.



(g) If one or more of the directorships elected with the Committed Shares are vacant and the Parties have been unable to secure the appointment of the replacement thereof by the board in office until the next regular
shareholders meeting in the terms of Article 32 of the Companies Law, and the Parties foresee that it will be impossible to obtain the majority necessary to adopt resolutions as controllers of Lan Chile, the Parties will recommend and persuade the
directors elected with the Committed Shares to refrain from attending board meetings until the vacant directorships have been filled. For these purposes, any of the Parties may require that the board convene a special shareholders meeting in order
to revoke the entire board of directors in office and elect a new one, and thus be able to fill the vacant directorship. Upon exercising this right, the Parties shall vote in favor of the revocation and proceed with the renewal of the board of
directors using the mechanisms established in Section 1.2 above.



5



---

1.4 Exclusivity. The Parties undertake not to enter into shareholders agreements or joint action
agreements with third parties, either in writing or verbally, in relation to the Committed Shares that prevent them from complying faithfully with the obligations arising from this Joint Action Agreement.



1.5 Scope. Committed Shares shall be understood not only
to be the 143,509,092 shares in Lan Chile mentioned in letter (d) of the Recitals but also all such other shares that Lan Chile may issue in the future, whether cash shares or paid-up shares, as well as all such preemptive rights or options of any
nature, either for a priority subscription of shares, of bonds convertible to shares or of any other securities that confer future rights in respect of Lan Chile, provided such shares or securities arise from, or bear a relationship to, the
Committed Shares.



ARTICLE SECOND

LIENS AND ATTACHMENTS



2.1 Liens.



(a) Except for the restrictions on the transfer of shares contained in the Shareholders Agreement and the exception indicated in Section 2.1(b) below,
none of the Parties may establish or tolerate the existence of any Lien on the Committed Shares. Lien shall be understood to be any real guarantee or any charge, lien, prohibition, third-party right, attachment, impediment or restriction
that might affect or hinder the free use, enjoyment or disposition of the Committed Shares.



(b) Each Party may pledge as much as 50% of the Committed Shares owned thereby to secure its own obligations specifically set down in the pledge agreement, but only provided the other Party consents thereto. Each
Party hereby consents to pledges that are at this time assessed on the Committed Shares owned by the other Party. When one Party wishes to grant new pledges in respect of the Committed Shares owned thereby, the other Party shall give its consent
thereto if the pledgee (hereinafter also the Pledgee) agrees, in the deed establishing the pledge, that the other Party shall, if the pledge is enforced, have the right to pay the Pledgee, prior to the auction of the pledged Committed
Shares, the lower of: (i) the sum owed by the pledgor to the Pledgee specifically determined in the pledge agreement; and (ii) the market price of the pledged Committed



6



---

Shares appraised at the average weighted exchange price of the last five exchange business days prior to payment. And, if the other Party makes this payment,
it shall have nullified the action of the Pledgee against the pledgor and be subrogated in the rights that the Pledgee has against the pledgor, including the entire real right of pledge. Hence, if the sum paid by the other Party is less than the sum
owed to the Pledgee, the balance of the Pledgees credit will not be benefited by the pledge.



2.2 Attachments or Other Measures. If all or part of the Committed Shares are assessed for any reason by any unpermitted Lien (including an
attachment petitioned by a Pledgee), the Party owning the Committed Shares undertakes to secure the removal of such Lien as soon as possible and, if more than 30 days pass without removal of the Lien, the Party owning such shares shall be deemed to
have defaulted on this Joint Action Agreement.



ARTICLE THIRD

COMPLIANCE



3.1 Good Faith. The Parties promise to comply with all provisions in this Joint Action Agreement, not only the text, but also the spirit hereof,
and undertake to act in good faith and transparently.



3.2
Liability. In addition to the personal liability of the Parties for faithful compliance with the obligations arising under this Joint Action Agreement, each Party shall be liable for the directors that are related thereto pursuant to Article
100 of the Companies Law or are appointed pursuant to Section 1.2(c) above applying in full the provisions of this Joint Action Agreement.



ARTICLE FOURTH

TERM



4.1 Termination.



(a) Any of the Parties may at any time, unilaterally, without reason,
terminate this Joint Action Agreement by written notice sent to the other Party and to the chairman of the board of directors of Lan Chile (hereinafter also the Notice of Termination).



7



---

(b) The Notice of Termination shall include an offer to sell the Committed Shares of the Party giving the
Notice of Termination to the other Party in the terms established in the Right of First Refusal contained in the Shareholders Agreement provided this Joint Action Agreement continues in full force until the transfer of the Committed Shares of one
Party is consummated in the terms established in the Shareholders Agreement.



4.2 Transfer. This Joint Action Agreement shall also terminate when one of the Parties transfers its Committed Shares to a third party in the terms established in the Shareholders Agreement.



ARTICLE FIFTH

DEFAULT CLAUSE



5.1 Default Clause. The Parties stipulate that in the event of default on any of the principal or accessory obligations stipulated in this Joint Action Agreement, the defaulting Party shall be sanctioned each
time by a fine or penalty that the Parties assess in advance in the equivalent in pesos, legal tender, to 15% of the value of the Committed Shares owned by the defaulting Party at the time of the breach, appraised at the average weighted exchange
trading price for the last five exchange business days.



5.2
Graduation.



(a) The arbitrator appointed pursuant to
Section 6.2 below shall be empowered to set and regulate prudently the fine or penalty that he decides to apply between: (i) 10,000 Unidades de Fomento that will be payable in pesos, legal tender, at the parity for the Unidad de Fomento reported by
the Central Bank of Chile or replacement or subrogate thereof in that function, in effect on the day of actual payment and no later than the third bank business day after the arbitral ruling condemning payment becomes final and binding; and (ii) the
penalty indicated in Section 5.1 above, considering for this purpose the nature and materiality of the breached obligation, how imputable it is against the defaulting Party and the damage caused to the non-defaulting Party.



8



---

(b) If, due to the nature of the breached obligation, it can be fulfilled or remedied alternatively or
substitutively and the defaulting Party is willing to fulfill or remedy the breach in that way, the arbitrator shall consider this circumstance in particular in attenuating the penalty and may even release the defaulting Party from any fine in this
case only.



(c) If the breached obligation is, by nature,
capable of specific performance and this is petitioned by the non-defaulting Party, the arbitrator may set the fine or penalty in the nature of a moratorium and may impose it as a fine or penalty on a daily or periodic basis until the defaulting
Party fulfills the obligation.



5.3 Waiver of Other
Damages. The Parties waive the rights stipulated in Article 1513 of the Civil Code to claim ordinary damages caused by default on this Joint Action Agreement and limit themselves, for all purposes of this Joint Action Agreement, to the
conventional indemnity stipulated or those set by the arbitrator in application of this Article Fifth.



5.4 Interest. The maximum conventional interest on adjustable transactions beyond 360 days or non-adjustable transactions out to one year, as the
case may be, shall apply in the event of delinquency or simple delay in the payment of the fine or penalty set by the arbitrator, from the day of delinquency or simple delay through the day of actual payment of the fine or penalty.



5.5 No Accumulation. Provided one same act or failure of a Party
implies default on this Joint Action Agreement and on the Shareholders Agreement, there will be one single fine or penalty for such act or failure under both agreements.



ARTICLE SIXTH

ARBITRATION



6.1 Arbitration Clause. Any
and all controversies, difficulties or differences arising among the Parties that originate in the interpretation, application, performance, default, validity, enforcement, voidance, effects or effectiveness of this Joint Action Agreement, of any of
the clauses or effects thereof, the foregoing list being by way of example only, shall be submitted to the hearing and ruling of an arbitrator (árbitro



9



---

arbitrador or amigable componedor). The arbitrator will be appointed by mutual consent of the Parties. If the Parties are unable to reach an
agreement on the person of the arbitrator, the Parties hereby appoint Mr. Sergio Urrejola Monckeberg as arbitrator, and if he is unable or unwilling to assume the position, Mr. Juan Carlos González, and if he is unable or unwilling to assume
the position, Mr. Arturo Yrarrázaval Covarrubias, and if he is unable or unwilling to assume the position, Mr. Felipe Larraín Bascuñan, and if he is unable or unwilling to assume the position, Mr. Enrique Barros Bourie. The mere
fact that one of the Parties requests acceptance of the position from the first arbitrator herein appointed shall imply the absence of an agreement thereamong in regard to such appointment. If none of those appointed is able or willing to accept the
arbitration, the appointment shall be made by the ordinary courts and it shall fall upon a deputy justice of the Supreme Court who has held that position for a period of no less than three years or, on a subsidiary basis, if there is no one who
meets that requirement on such date, upon a deputy justice of the Santiago Court of Appeals who has held that position for the same period of time. The decision rendered by the arbitrator cannot be appealed.



6.2 Other Powers. The arbitrator shall be specially empowered to
decide on the voidance or validity of the arbitration clause and on the scope and ambit of his own competence. The arbitrator shall also have, in particular, the attributions and powers conferred thereupon in Section 5.2 above.



ARTICLE SEVENTH

7.2 Domicile. For all purposes of this Joint Action Agreement, the Parties elect their domicile as the jurisdiction of the Santiago Court of
