between

THE BOEING COMPANY

and

LAN AIRLINES S.A.

Relating to Boeing Model 787-916/787-816 Aircraft

THIS SUPPLEMENTAL AGREEMENT, entered into as of the 8 day of July of 2010, (hereinafter called “Supplemental Agreement 2” or “SA-2”by and between THE BOEING COMPANY, a Delaware corporation (hereinafter called “Boeing”), and LAN Airlines S.A., a Chilean corporation (hereinafter called “Customer”);

WITNESSETH:

WHEREAS, the parties entered into that certain Purchase Agreement No. 3256, dated as of October 29, 2007 relating to the purchase and sale of Boeing Model 787-916 and Model 787-816 aircraft (hereinafter referred to as "Aircraft") which agreement, including all tables, exhibits, supplemental exhibits and specifications thereto, together with all letter agreements then or thereafter entered into that by their terms constitute part of such purchase agreement and as such purchase agreement may be amended or supplemented from time to time, is hereinafter called the "Purchase Agreement;"

WHEREAS, the parties have agreed to accelerate the delivery of two (2) Model 787-816 Aircraft to September 2011 and

WHEREAS, Boeing and Customer have agreed to amend the Purchase Agreement to incorporate the above changes;

NOW THEREFORE, in consideration of the mutual covenants herein contained, the parties hereto agree to amend the Purchase Agreement as follows:

1. Delivery of September 2011 Accelerated Aircraft

1.1.     Delivery of the two (2) 787-816 Aircraft are accelerated as shown in the chart below (hereinafter called “September 2011 Accelerated Aircraft”).

Serial Numbers	Original Delivery Month	Accelerated Delivery Month
38471	Sep 2015	September 2011
38466	Oct 2015	September 2011

2. Engine Selection.

Customer has selected Rolls Royce Engines for its September 2011 Accelerated Aircraft.  Sections of the Purchase Agreement related to GENX engines no longer apply to the September 2011 Accelerated Aircraft.

3. Table of Contents.

The “Table of Contents” to the Purchase Agreement is revised to reflect the changes made by this SA-2.  The revised Table of Contents is attached hereto.

4. Articles.

4.1.   [***]:

“[***].”

5.      Tables.

The Aircraft Information Tables are revised a) to delete the September 2011 Accelerated Aircraft from Table 1-ROLLS 787-816 and b) to add Table 5 for the September 2011 Accelerated Aircraft.  The revised Table 1-ROLLS 787-816 and Table 5 are attached hereto and identified with the SA-2 legend.

6. Exhibits and Supplemental Exhibits.

6.1           Exhibit A1, “Aircraft Configuration” relating to 2011 787-816 Aircraft provides the configuration for the September 2011 Accelerated Aircraft.  If Boeing defers the delivery of one or both of the September 2011 Accelerated Aircraft so that the new delivery date is June 2012 or later, the deferred aircraft will have the same configuration as Customer’s Aircraft delivering in May 2012.  Boeing and Customer continue to analyze what, if any, of Customer’s May 2012 configuration could be incorporated into the Aircraft delivering in 2011 during production.

6.2.          Subject to paragraph 6.1, BFE seats are not available for the September 2011 Accelerated Aircraft.  Supplemental Agreements “Buyer Equipment Variables” (BFE1) and “Buyer Equipment Variables for 2012-2013 Aircraft” (BFE2) do not apply to the September 2011 Accelerated Aircraft.  If Boeing defers the delivery of one or both of the September 2011 Accelerated Aircraft so that the new delivery date is June 2012 or later, “Buyer Equipment Variables for 2012-2013 Aircraft” (BFE2) will be revised to include such deferred September 2011 Accelerated Aircraft.

7. Letter Agreements.

7.1.          For the Accelerated Aircraft and the September 2011 Accelerated Aircraft the Initial Provisioning Meeting called out in paragraph 2.2 of Letter Agreement 3256-01 entitled “Spare Parts Initial Provisioning” was held in March 2010.

7.2.          The September 2011 Accelerated Aircraft configuration is finalized at the time SA-2 is signed.  Therefore, except for paragraphs 1.2.4 and 1.2.5, Letter Agreement 3256-02, “Boeing Model 787 Open Configuration Matters” does not apply to the September 2011 Accelerated Aircraft.  Master changes may still be processed in accordance with Boeing standard processes.

7.3.          Letter Agreement 6-1162-ILK-0310R1 entitled “Special Matters” is revised to address the economic considerations for the September 2011 Accelerated Aircraft.  The revised Letter Agreement 6-1162-ILK-0310R2 is attached hereto.

7.4.          Letter Agreement 6-1162-ILK-0312 entitled “Promotional Support Agreement” is revised and the revised Letter Agreement 6-1162-ILK-0312R1 attached hereto.

7.5.          [***].

7.6.          [***].

7.7.          [***].

7.8.          For the Accelerated Aircraft and the September 2011 Accelerated Aircraft the Planning Conferences called out in Letter Agreement 6-1162-ILK-0323 entitled “Special Matters Customer Support Document”, paragraph 1 revising CS1 Part 1, Art. 2.1 and Part 3, item 2 were in March 2010.

7.9.          Letter Agreement 6-1162-ILK-0326 entitled “Special Matters Customer 787 Fleet” does not apply to the September 2011 Accelerated Aircraft.

7.10.        [***].

7.12.        [***].

7.13.        Letter Agreement 6-1162-KSW-6473 entitled “Delivery Flexibility for September 2011 Accelerated Aircraft” is added to the Purchase Agreement and attached hereto.

8. [***].

8.1.          [***].

8.2.          The parties recognize that if Boeing exercises its right to slide either or both September 2011 Accelerated Aircraft the advance payments owed will change.  Therefore no advance payment is required at the signing of SA-2.  On August 1, 2010 Customer will either pay the advance payment amount called out in paragraph 8.1 if the delivery months remains September 2011 or a revised advance payment amount based on the new delivery positions.

9. Confidential Treatment.

Boeing and Customer understand that the commercial and financial information contained in this Supplemental Agreement is considered by the parties as confidential (Confidential Information) and both agree not to disclose such Confidential Information except as provided herein.  In addition to the parties’ respective officers, directors and employees who need to know the Confidential Information and who understand the obligation to keep it confidential, the parties may disclose Confidential Information (1) to the extent required by law and (2) to its agents, auditors and advisors who need to know the Confidential Information for purposes of enabling each party to understand, perform its obligations under, or receive the benefits of, this Agreement and who have agreed not to use or disclose the Confidential Information for any other purpose without the other party’s prior written consent.  In the event that a party concludes that disclosure of Confidential Information contained in this Supplemental Agreement 2 is required by applicable law, the party will so advise the other party promptly in writing and endeavor to protect the confidentiality of such Confidential Information to the widest extent possible.  In the event of a legal dispute with Boeing, nothing herein will preclude Customer from sharing with its legal counsel information necessary for purposes of enabling counsel to advise or represent Customer provided that so long as Customer causes its legal counsel to maintain the confidentiality of information that is the subject of this Article.  Except as provided in the assignment provisions of Article 10 of the Special Matters Letter Agreement 6-1162-ILK-0310R2, Customer will not disclose this Supplemental Agreement 2 for purposes of financing payments without the prior written consent of Boeing, which consent will be provided once the financier enters into a Non Disclosure Agreement with Boeing in form and substance reasonably satisfactory to Boeing, which will include agreeing not to disclose or use Confidential Information except for the purpose set forth herein. This provision shall not apply to any Confidential Information that is in the public domain except that a party will be liable to the other for breach of its obligations under this provision if the Confidential Information entered the public domain as a consequence of a wrongful act or omission on its part.

The Purchase Agreement shall be deemed amended to the extent herein provided and as amended shall continue in full force and effect.

6. Economic Considerations for the Option Aircraft.

Subject to Customer’s adherence to the Limitations on Use, Boeing agrees that the Option Aircraft [***].

[***]:

(iii) For 2017 delivery year option aircraft: Customer to provide Boeing with its notice of option exercise rights no later than July 1, 2014; and

(iv) for 2018 delivery year option aircraft: Customer to provide Boeing with its notice of option exercise rights no later than July 1, 2015.

Notwithstanding Article 4.2 of the Option Aircraft Letter, [***].  A sample form of supplemental agreement (illustrative of the contractual documentation incident to implementation of the Customer’s exercise of its rights in respect of the purchase of Option Aircraft) that is acceptable to Boeing is attached as Appendix 1 to this Letter Agreement.  Appendix 1 reflects a Customer exercise of its rights in respect of two (2) Option Aircraft; however, the parties agree that Customer may exercise its rights in respect of a minimum of one (1) Option Aircraft so long as such Customer exercise occurs no later than the applicable Option Exercise Date.

7. Economic Considerations for the Substitution Aircraft.

In the event of substitution of an Aircraft by the Customer pursuant to the Aircraft Model Substitution Letter Agreement to the Purchase Agreement, Boeing agrees to provide Customer with [***].  A sample form of supplemental agreement (illustrative of the contractual documentation incident to implementation of the Customer’s exercise of its substitution rights in respect of one (1) Boeing Model 787-916 Aircraft to replace the purchase of one (1) Boeing Model 787-816 Aircraft) that is acceptable to Boeing is attached as Appendix 2 to this Letter Agreement.

8. Correction Time Objectives.

In the event that Boeing is able to make improvements to Correction Time Objectives as defined in Article 8.3.1 of Exhibit C to the AGTA, Product Assurance Document, then Boeing will revise the referenced Article to reflect the revision, e.g., to reflect subsequent schedule improvement to the extent realized.

Aircraft Model	Fuel Provided
Boeing Model 787 Aircraft,  including all minor models	3,000

10. Assignment.

Any assignment by Customer of any benefits, entitlements, or services described in this Letter Agreement requires Boeing's prior written consent.  Further, Customer will not reveal to any third party the amount of the credit memoranda provided to Customer by Boeing without Boeing’s prior written consent and subject to such circumstances as Boeing may reasonably require.

Boeing will not unreasonably withhold consent to Customer’s request to assign, as security, rights in the Purchase Agreement if done for purposes of obtaining financing or for such other purpose consistent with fulfilling its obligations under the Purchase Agreement.  Boeing’s consent will be conditioned on all parties accepting Boeing’s customary conditions for consenting to an assignment, including, but not limited to, the following: assignor and assignee indemnification of Boeing for any actions taken by an assignee under any assignment agreement; Boeing’s right to exercise the manufacturer’s option to assume Customer’s rights under the Purchase Agreement in the event of a default under an assignment agreement; and confidentiality.  A Party that is

i.       bound by a customary confidentiality agreement;

ii.      neither an airplane manufacturer nor an airline;  and

iii.     responding to a Customer request for proposals to provide financing of Aircraft pursuant to the Purchase Agreement, including pre-delivery payment financing

shall be deemed a “Financing Party”.

Without Boeing’s consent, Customer may represent to any Financing Party that Boeing will provide to that Financing Party, concurrently with the delivery of each of the Aircraft to that Financing Party, [***] each Aircraft escalated to the month of delivery in the same manner as the Airframe Price as described in Supplemental Exhibit AE-1.  Insofar as such Financing Party is concerned, this Financier Credit Memorandum shall be in lieu of any other provision in this Letter Agreement. When the Customer identifies a Financing Party and the preliminary terms of an assignment under which pre-delivery payment financing (PDP) or aircraft purchase financing could be provided, at Customer’s request, Boeing agrees to enter into discussions with the Customer to consider whether an additional credit memorandum can be assigned, with the goal of helping Customer obtain third-party financing.

Boeing will consent to any reasonable request by Customer to assign the Purchase Agreement to an affiliate provided that Boeing is provided with an adequate  guarantee of performance of all obligations under this Purchase Agreement and in a form reasonably satisfactory to Boeing.

Customer understands that Boeing is not required under any circumstances to consent to an assignment that would constitute a novation.

11.           MTOW and Other Configuration Matters.

Boeing recognizes that Customer requires early notification of Development Changes, incorporated into the Detail Specification, and Manufacturer Changes applicable to the Aircraft so Customer can evaluate, in a timely manner, the effect of such changes on maintenance and operation of the Aircraft.  Boeing will provide to Customer notification of such Developmental Changes and Manufacturer Changes affecting Customer's airplanes through Boeing's standard notification process.

This provision shall not apply to any Confidential Information that is in the public domain except that a party will be liable to the other for breach of its obligations under this provision if the Confidential Information entered the public domain as a consequence of a wrongful act or omission on its part.
