(gg) Absence of Labor Dispute. Neither the Company nor any of its subsidiaries is engaged in any unfair labor practice; except for matters which would not, individually or in the aggregate, have a Material Adverse Effect, (i) there is (A) no unfair labor practice complaint pending or, to the Company’s best knowledge, threatened against the Company or any of its Significant Subsidiaries before any government entity and no grievance or arbitration proceeding arising out of or under collective bargaining agreements is pending or threatened, (B) no strike, labor dispute, slowdown or stoppage pending or, to the Company’s best knowledge, threatened against the Company or any of its Significant Subsidiaries and (C) no union representation dispute currently existing concerning the employees of the Company or any of its Significant Subsidiaries, and (ii) to the Company’s best knowledge, (A) no union organizing activities are currently taking place concerning the employees of the Company or any of its subsidiaries and (B) there has been no violation of any federal, state, local or foreign law or regulation relating to discrimination in the hiring, promotion or pay of employees, any applicable wage or hour laws or any provision of the Employee Retirement Income Security Act of 1974, as amended, or the rules and regulations promulgated thereunder (collectively, “ERISA”) concerning the employees of the Company or any of its Significant Subsidiaries.

(kk) Compliance with the Xxxxxxxx-Xxxxx Act. There is and has been no failure on the part of the Company or, to the Company’s best knowledge, on the part of any of the Company’s officers or directors, in their capacities as such, to comply in all material respects with any provision of the Xxxxxxxx-Xxxxx Act of 2002 and the rules and regulations promulgated in connection therewith applicable to the Company as of the date hereof.

(ll) Foreign Corrupt Practices Act. Neither the Company nor, to the best knowledge of the Company, any director, officer, agent, employee, affiliate or other person acting on behalf of the Company or any of its subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a violation by such persons of the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder (the “FCPA”), including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA and the Company and, to the best knowledge of the Company, its affiliates have conducted their businesses in compliance with the FCPA and have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith.

-15-

(qq) Waiver of Immunity by the Company. The Company and its obligations under this Agreement are subject to civil and commercial law and to suit and neither the Company nor any of its properties, assets or revenues has any right of immunity under Chilean or New York law from any legal action, suit or proceeding, from the giving of any relief in any such legal action, suit or proceeding, from setoff or counterclaim, from the jurisdiction of any Chilean, New York State or U.S. federal court, from service of process, attachment upon or prior to judgment, or attachment in aid of execution of judgment, or from execution of a judgment, or other legal process or proceeding for the giving of any relief or for the enforcement of a judgment, in any such court, with respect to its obligations, liabilities or any other matter under or arising out of or in connection with this Agreement and, to the extent that the Company or any of its properties, assets or revenues may have or may hereafter become entitled to any such right of immunity in any such court in which proceedings may at any time be commenced, the Company has waived or will waive such right to the extent permitted by law and has consented to such relief and enforcement as provided in Section 18 of this Agreement.

(rr) Consent to Jurisdiction; Appointment of Agent for Service of Process. The Company has the power to submit, and pursuant to this Agreement has legally, validly, effectively and irrevocably submitted to the exclusive personal jurisdiction of any federal or state court in the State of New York, County of New York, and has validly and irrevocably waived any objection to the laying of the venue of any such suit, action or proceeding brought in any such court and has the power to designate, appoint and empower, and pursuant to this Agreement has legally, validly and effectively designated, appointed and empowered, CorpBanca New York Branch, 000 Xxxxx Xxxxxx, 0^xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000 (“Authorized Agent”) as its agent for service of process in any suit or proceeding based on or arising under this Agreement in any federal or state court in the State of New York, County of New York, as provided in Section 19 of this Agreement.

(ss) Judgments. Any final and conclusive monetary judgment against the Company of any New York State or Federal court sitting in New York City based upon this Agreement and the Indenture shall be recognized and enforced by the courts of the Republic of Chile, without re-examining or re-litigating the merits of the original action, provided the following conditions are met (the existence or non-existence of which would be determined by the Corte Suprema de Justicia (Supreme Court of Chile)): (A) if there is a treaty between Chile and the country where the judgment was rendered with respect to the enforcement of foreign judgments, the provisions of such treaty will apply, (B) in the absence of a treaty, the rules of reciprocity will apply to the enforcement of judgments; if the country where the judgment was passed does not recognize judgments of Chilean courts, such foreign judgments may not be enforced in Chile, and (C) if the previous rules cannot be applied, the monetary judgment of foreign courts will have in Chile the same effect as the judgments given by Chilean courts, provided that: (w) the foreign monetary judgment does not contain anything contrary to the laws of Chile, (x) the foreign monetary judgment is not contrary to public policy of Chile and does not affect in any way properties situated in Chile, which are subject exclusively to the jurisdiction of local courts, (y) the defendant against whom the enforcement is sought has been given personal notice of the proceedings in accordance

-16-

with Chilean law and has been afforded a real opportunity to appear before the foreign court and defend his case, which are factual issues that must be established when obtaining in Chile the enforcement of a foreign monetary judgment. Personal service made upon the Company’s process agent, assuming that manner of service to be valid under the local law of the place where service was made, would constitute due notice. However, under Chilean law, service of process by mail will not be deemed to constitute due service of process for the above purposes, and (z) the foreign monetary judgment is final (i.e., not subject to any recourse), conclusive and enforceable under the laws of the country where it was rendered. Upon compliance with the above, the courts in the Republic of Chile shall enforce a final and conclusive monetary judgment rendered by any New York State or Federal court sitting in New York City, in accordance with the procedure applicable to the enforcement of final and conclusive foreign judgments in Chile under the provisions of the Chilean Civil Procedure Code (Código de Procedimiento Civil). To enforce a foreign judgment in Chile, a judgment must be submitted to the Supreme Court of Chile, in the form of a legalized and officially translated copy. The Supreme Court of Chile will hear arguments from the party against whom enforcement is sought, but such hearing will be limited to aspects relating to such enforcement and not to substantive issues resolved in the foreign judgment. As of the date hereof, there is no treaty between the Republic of Chile and the United States on the enforcement of foreign judgments. In practice, due to the difficulties of proving in each case whether the reciprocity rule on the enforcement of foreign judgments applies or not in respect of a specific country, the Supreme Court of Chile’s approach on the matter has generally been the examination of whether circumstances in letters (w) and (x) above are duly met by such foreign judgment.

(tt) Except as described in the Registration Statement and the Prospectus, there are no contracts, agreements or understandings in relation to the offering of the Notes between the Company and any person that would give rise to a valid claim against the Company or the Underwriters for a brokerage commission, finder’s fee or other like payment.

(uu) No forward-looking statement (within the meaning of Section 27A of the Act and Section 21E of the Exchange Act) contained in the Registration Statement, the Pricing Prospectus and the Prospectus has been made or reaffirmed without a reasonable basis or has been disclosed other than in good faith.

(vv) Any certificate signed by any officer of the Company pursuant to Section 7 and delivered to the Underwriters or to the counsel for the Underwriters for the benefit of the Underwriters shall be deemed a representation and warranty by the Company to the Underwriters as to the matters covered thereby.

(ww) The Company is a “foreign private issuer” as defined in Rule 3b-4 under the Exchange Act as of the date hereof.

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 8(c) below) any such settlement is effected with the written consent of the Company;

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of one counsel chosen by the Underwriters (together with local counsel in each jurisdiction)), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above; provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, the Pricing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

-28-

failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 8(a) above, counsel to the indemnified parties shall be selected by the Underwriters, and, in the case of parties indemnified pursuant to Section 8(b) above, counsel to the indemnified parties shall be selected by the Company.

In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 8 or Section 9 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 8(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 9. Contribution.

(a) If the indemnification provided for in Section 8 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Notes pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only

-29-

the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

(b) The relative benefits received by the Company, on the one hand, and the Underwriter, on the other hand, in connection with the offering of the Notes pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discount received by the Underwriter, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Notes as set forth on the cover of the Prospectus.

(c) The relative fault of the Company, on the one hand, and the Underwriter, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(d) The Company, and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 9. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 9 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

(e) Notwithstanding the provisions of this Section 9, the Underwriters shall not be required to contribute any amount in excess of the underwriting commissions received by it in connection with the Notes underwritten by it and distributed to the public.

(g) For purposes of this Section 9, each person, if any, who controls the Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and the Underwriter’s Affiliates and selling agents shall have the same rights to contribution as the Underwriter, and each director of the Company, each officer of the Company, and each person, if any, who controls the Company within the meaning of

-30-

Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company.

If within thirty six hours after such default by any Underwriter you do not arrange for the purchase of such Notes, then the Company shall be entitled to a further period of thirty six hours within which to procure another party or other parties satisfactory to you to purchase such Notes on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Notes, or the Company notifies you that it has so arranged for the purchase of such Notes, you or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Notes.

(b) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate number of such Notes which remains unpurchased does not exceed one eleventh of the aggregate number of all the Notes to be purchased at the Time of Delivery, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Notes which such Underwriter agreed to purchase hereunder at the Time of Delivery and, in addition, to require each non defaulting Underwriter to purchase its pro rata share (based on the number of Notes which such Underwriter agreed to purchase hereunder) of the Notes of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate number of such Notes which remains unpurchased exceeds one eleventh of the aggregate number of all the Notes to be purchased at such Time of Delivery, or if the Company shall not exercise the right described in subsection (b) above to require non defaulting Underwriters to purchase Notes of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Sections 8 and 9,

-31-

respectively, hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

SECTION 11. Termination of Agreement. If this Agreement shall be terminated pursuant to Section 10 hereof, the Company shall not then be under any liability to any Underwriter except as provided in Sections 6 and 8 hereof; but, if for any other reason, the Notes are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through you for all out of pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Notes not so delivered, but the Company shall then be under no further liability to any Underwriter except as provided in Sections 6 and 8 hereof.

SECTION 12. Representations, Warranties and Agreements to Survive. The respective indemnities, agreements, representations and warranties of the Company and the Underwriter, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of the Underwriter or any controlling person of the Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Notes or termination of this Agreement.

The term “spot rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, the relevant currency.

SECTION 21. Governing Law. This Agreement and any non-contractual matters related to this Agreement shall be governed by and construed in accordance with the

-34-

laws of the State of New York without regard to principles of conflict of laws that would result in the application of any law other than the laws of the State of New York. The Company agrees that any suit or proceeding arising in respect of this Agreement or the transactions contemplated hereby will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the Company agrees to submit to the exclusive jurisdiction of, and to venue in, such courts.

SECTION 22. TRIAL BY JURY. THE COMPANY AND THE UNDERWRITER HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

SECTION 23. Payments Free and Clear. All payments to be made by the Company under this Agreement shall be paid free and clear of and without deduction or withholding for or on account of, any present or future taxes, levies, imposts, duties, fees, assessments or other charges of whatever nature, imposed by Chile, or by any department, agency or other political subdivision or taxing authority thereof, and all interest, penalties or similar liabilities with respect thereto (collectively, “Chilean Taxes”). If any Chilean Taxes are required by law to be deducted or withheld in connection with such payments, the Company will increase the amount paid so that the full amount of such payment is received by the Underwriter. The Company will furnish to the Underwriter official acknowledgment of the relevant tax authority evidencing any payment of any Chilean Taxes in respect of which the Company has paid any increased amounts pursuant to this paragraph.

SECTION 24. Disclosure of Tax Consequences. Notwithstanding anything herein to the contrary, the Company is authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company relating to that treatment and structure, without the Underwriter’s imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

SECTION 25. Termination.

(a) The Underwriter may terminate this Agreement, by notice to the Company, at any time at or prior to the Time of Delivery (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus (exclusive of any supplement thereto) or the Pricing Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial

-35-

markets in Chile, Colombia or in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in Chilean, Colombian or the United States national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Underwriter, impracticable or inadvisable to market the Notes or to enforce contracts for the sale of the Notes, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Xxxxxxxx Stock Exchange, if trading in the Company’s common shares or ADSs, if any, has been suspended by the Commission or the NYSE, or if trading generally on the Xxxxxxxx Stock Exchange or the NYSE has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, FINRA or any other United States or Chilean governmental authority, or (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe, or (v) if a banking moratorium has been declared by any of Chilean, U.S. federal or New York authorities; and

(b) If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 6 hereof, and provided further that Sections 1, 8, 9, 12, 18, 19, 20, 21, 22 and 23 shall survive such termination and remain in full force and effect.

SECTION 26. Counterparts. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.
