Ladies and Gentlemen:

Bancolombia S.A., a Colombian banking institution incorporated under the laws of the Republic of Colombia (“Colombia”) as a sociedad anónima (the “Company”), proposes to issue and sell to the underwriters named in Schedule A hereto (the “Underwriters”), for whom you are acting as representatives, an aggregate of 17,788,008 preferred shares, Ps.500 par value per share (the “Preferred Shares”) of the Company in the form of American Depositary Shares (the “ADSs”) (such ADSs hereinafter referred to as the “Firm Securities”). In addition, the Company proposes to grant to the Underwriters the option to purchase from the Company up to an additional 2,668,196 Preferred Shares, in the form of ADSs (the “Additional Securities”). The Firm Securities and the Additional Securities are hereinafter collectively referred to as the “Securities.”

You have requested that the Company deposit on behalf of the Underwriters all the Preferred Shares underlying the ADSs to be purchased by them hereunder pursuant to the Deposit Agreement, as amended and restated as of January 24, 2008 (the “Deposit Agreement”), by and among the Company, The Bank of New York Mellon, as depositary (the “Depositary”) and all owners and beneficial owners from time to time of the ADRs (as defined below). Upon deposit of any Preferred Shares, the Depositary will issue ADSs representing the Preferred Shares so deposited (such Preferred Shares, the “Underlying Shares”).

The ADSs will be evidenced by American Depositary Receipts (the “ADRs”). Each ADS will represent four (4) Preferred Shares and each ADR may represent any number of ADSs. Each reference herein to ADRs shall include the corresponding ADSs, and vice versa.

The Company has prepared and filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the “Act”), with the Securities and Exchange Commission (the “Commission”) a registration statement on Form F-3 (File No. 333-168077) under the Act (the “registration statement”), including a prospectus, which registration statement incorporates by reference documents which the Company has filed, or will file, in accordance with the provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the “Exchange Act”). Such registration statement has become automatically effective upon filing under the Act.

Except where the context otherwise requires, “Registration Statement,” as used herein, means the registration statement, as amended at the time of such registration statement’s effectiveness for purposes of Section 11 of the Act, as such section applies to the respective Underwriters (the “Effective Time”), including (i) all documents filed as a part thereof or incorporated or deemed to be incorporated by reference therein, (ii) any information contained or incorporated by reference in a prospectus filed with the Commission pursuant to Rule 424(b) under the Act, to the extent such information is deemed, pursuant to Rule 430B under the Act, to be part of the registration statement at the Effective Time, and (iii) any registration statement filed to register the offer and sale of Securities pursuant to Rule 462(b) under the Act.

For the purposes of this Agreement, the “Applicable Time” is 8:00 p.m. (Eastern time) on the date of this Agreement.

The terms “herein,” “hereof,” “hereto,” “hereinafter” and similar terms, as used in this Agreement, shall in each case refer to this Agreement as a whole and not to any particular section, paragraph, sentence or other subdivision of this Agreement. The term “or,” as used herein, is not exclusive.

The Company and the Underwriters agree as follows:

1. Sale and Purchase. Upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Company agrees to issue and sell to the respective Underwriters and each of the Underwriters, severally and not jointly, agrees to purchase from the Company the number of Firm Securities set forth opposite the name of such Underwriter in Schedule A hereto, subject to adjustment in accordance with Section 7 hereof, for the aggregate purchase price set forth opposite the name of such Underwriter in Schedule A hereto. The Company is advised by you that the Underwriters intend (i) to make a public offering of their respective portions of the Firm Securities as soon after the effectiveness of this Agreement as in your judgment is advisable and (ii) initially to offer the Firm Securities upon the terms set forth in the Prospectus. You may from time to time increase or decrease the public offering price after the initial public offering to such extent as you may determine.

In addition, the Company hereby grants to the several Underwriters the option (the “Option”) to purchase, and upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Underwriters shall have the right to purchase, severally and not jointly, from the Company, ratably in accordance with the number of Firm Securities to be purchased by each of them, all or a portion of the Additional Securities set forth opposite the name of such Underwriter in Schedule B hereto at a purchase price of U.S.$58.77000 per ADS less an amount per share equal to any dividends or distributions declared by the Company and payable on the Firm Securities but not on the Additional Securities. The Option may be exercised by the Representatives on behalf of the several

Underwriters at any time and from time to time on or before the thirtieth day following the date of this Agreement, by written notice to the Company. Such notice shall set forth the aggregate number of Additional Securities as to which the Option is being exercised and the date and time when the Additional Securities are to be delivered (any such date and time being herein referred to as an “additional time of purchase”); provided, however, that no additional time of purchase shall be earlier than the “time of purchase” (as defined in Section 2 below) nor, unless you and the Company otherwise agree in writing, except with respect to any Additional Securities to be purchased at the “time of purchase,” earlier than the second business day after the date on which the Option shall have been exercised, nor later than the tenth business day after the date on which the Option shall have been exercised. The number of Additional Securities to be sold to each Underwriter shall be the number which bears the same proportion to the aggregate number of Additional Securities being purchased as the number of Firm Securities set forth opposite the name of such Underwriter on Schedule A hereto bears to the total number of Firm Securities subject, in each case, to such adjustment as the Representatives may determine to eliminate fractional shares and subject to adjustment in accordance with Section 7 hereof.

The Company acknowledges and agrees that the Underwriters may offer and sell Securities to or through any affiliate of Underwriters and that any such affiliate may offer and sell Securities purchased by it to or through the Underwriters.

In addition, the Company agrees that it shall pay, at the time of purchase (as defined herein), to the Underwriters a special structuring fee (the “Special Structuring Fee”) of $1,099,149.90.

2. Payment and Delivery. Payment of the purchase price for the Firm Securities shall be made to the Company by Federal Funds (same day) wire transfer against delivery of the Firm Securities which shall be evidenced by one or more global certificates to you through the facilities of The Depository Trust Company (“DTC”) for the respective accounts of the Underwriters. Such payment and delivery shall be made at 10:00 A.M., New York City time, on February 6, 2012 (unless another time shall be agreed to by you and the Company or unless postponed in accordance with the provisions of Section 7 hereof; provided that such date is a business day and a day on which commercial banks in Colombia are not legally obliged or authorized to close). The time at which such payment and delivery are to be made is hereinafter sometimes called the “time of purchase.” Electronic transfer of the ADR certificates evidencing the Firm Securities shall be made to you at the time of purchase in such names and in such denominations as you shall specify.

Payment of the purchase price for the Additional Securities shall be made at the additional time of purchase in the same manner and at the same office as the payment for the Firm Securities. Electronic transfer of the ADR Certificates evidencing the Additional Securities shall be made to you at the additional time of purchase in such names and in such denominations as you shall specify.

6. Effective Date of Agreement; Termination. This Agreement shall become effective when the parties hereto have executed and delivered this Agreement.

The obligations of the several Underwriters hereunder shall be subject to termination in the absolute discretion of the Underwriters if (i) since the Applicable Time there has been any change or any development involving a prospective change in the business, properties, management, financial condition or results of operations of the Company and the subsidiaries taken as a whole, the effect of which change or development is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Registration Statement, the Disclosure Package or the Prospectus or (ii) since the Applicable Time there shall have occurred: (A) a suspension or material limitation in trading in securities generally on the NYSE, or the Bolsa de Valores de Colombia (the Colombian Stock Exchange); (B) a suspension or material limitation in trading in the Company’s securities on the NYSE; (C) a general moratorium on commercial banking activities declared by either federal, Colombian or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States or Colombia; (D) an outbreak or escalation of hostilities or acts of terrorism involving the United States or Colombia or a declaration by the United States or Colombia of a national emergency or war; (E) a change or development involving a prospective change in Colombian taxes affecting the Company, the Securities or the transfer thereof or the imposition of exchange controls by Colombia, in each case that may limit or in any way would materially and adversely affect the financial markets or the market for the Securities or materially impair the ability of the Underwriters to purchase, hold or effect resales of the Securities on the terms and in the manner contemplated by this Agreement, the Registration Statement, the Disclosure Package and the Prospectus; or (F) any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (D), (E) or (F), in the sole judgment of the Representatives, makes it impractical or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Registration Statement, the Disclosure Package or the Prospectus or (iii) since the Applicable Time, there shall have occurred any downgrading, or any notice or announcement shall have been given or made of: (A) any intended or potential downgrading or (B) any watch, review or possible change that does not indicate an affirmation or improvement in the rating accorded any securities of or guaranteed by the Company by any “nationally recognized statistical rating organization,” as that term is defined in Rule 436(g)(2) under the Act.

If the Representatives elect to terminate this Agreement as provided in this Section 6, the Company and each other Underwriter shall be notified promptly in writing.

If the sale to the Underwriters of the Securities, as contemplated by this Agreement, is not carried out by the Underwriters for any reason permitted under this Agreement, or if such sale is not carried out because the Company shall be unable to comply with any of the terms of this Agreement, the Company shall not be under any obligation or liability under this Agreement (except to the extent provided in Sections 8 and 9 hereof); and the Underwriters shall be under no obligation or liability to the Company under this Agreement (except to the extent provided in Section 8 hereof) or to one another hereunder; provided, however, that Sections 3, 12, 14, 20 and 21 shall also survive termination and remain in full force and effect.

7. Increase in Underwriters’ Commitments. Subject to Sections 5 and 6 hereof, if any Underwriter shall default in its obligation to take up and pay for the Firm Securities to be purchased by it hereunder (otherwise than for a failure of a condition set forth in Section 5 hereof or a reason sufficient to justify the termination of this Agreement under the provisions of Section 6 hereof) and if the number of Firm Securities which all Underwriters so defaulting shall have agreed but failed to take up and pay for does not exceed 10% of the total number of Firm Securities, the non-defaulting Underwriters (including the Underwriters, if any, substituted in the manner set forth below) shall take up and pay for (in addition to the aggregate number of Firm Securities they are obligated to purchase pursuant to Section 1 hereof) the number of Firm Securities agreed to be purchased by all such defaulting Underwriters, as hereinafter provided. Such Securities shall be taken up and paid for by such non-defaulting Underwriters in such amount or amounts as you may designate with the consent of each Underwriter so designated or, in the event no such designation is made, such Securities shall be taken up and paid for by all non-defaulting Underwriters pro rata in proportion to the aggregate number of Firm Securities set forth opposite the names of such non-defaulting Underwriters in Schedule A hereto.

Without relieving any defaulting Underwriter from its obligations hereunder, the Company agrees with the non-defaulting Underwriters that it will not sell any Firm Securities hereunder unless all of the Firm Securities are purchased by the Underwriters (or by substituted Underwriters selected by you with the approval of the Company or selected by the Company with your approval).

If a new Underwriter or Underwriters are substituted by the Underwriters or by the Company for a defaulting Underwriter or Underwriters in accordance with the foregoing provision, the Company or you shall have the right to postpone the time of purchase for a period not exceeding five business days in order that any necessary changes in the Registration Statement and the Prospectus and other documents may be effected.

The term “Underwriter” as used in this Agreement shall refer to and include any Underwriter substituted under this Section 7 with like effect as if such substituted Underwriter had originally been named in Schedule A hereto.

If the aggregate number of Firm Securities which the defaulting Underwriter or Underwriters agreed to purchase exceeds 10% of the total number of Firm Securities which all Underwriters agreed to purchase hereunder, and if neither the non-defaulting Underwriters nor the Company shall make arrangements within the five business day period stated above for the purchase of all the Firm Securities which the defaulting Underwriter or Underwriters agreed to purchase hereunder, this Agreement shall terminate without further act or deed and without any liability on the part of the Company to any Underwriter and without any liability on the part of any non-defaulting Underwriter to the Company; provided, however, that Sections 3, 12, 14, 20 and 21 shall also survive termination and remain in full force and effect. Nothing in this paragraph, and no action taken hereunder, shall relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

8. Indemnity and Contribution

(a) The Company agrees to indemnify, defend and hold harmless each Underwriter, its affiliates (as such term is defined in Rule 501(b) of the Act), directors and officers, and any person who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, any such Underwriter or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Underwriter furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in, the Registration Statement or arises out of or is based upon any omission or alleged omission to state a material fact in the Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact included in any Prospectus (the term Prospectus for the purpose of this Section 8 being deemed to include any Base Prospectus, any Pre-Pricing Prospectus, the Prospectus Supplement, the Prospectus and any amendments or supplements to the foregoing), in any Permitted Free Writing Prospectus, in any “issuer information” (as defined in Rule 433 under the Act) of the Company or in any Prospectus together with any combination of one or more of the Permitted Free Writing Prospectuses, if any, or arises out of or is based upon any

omission or alleged omission to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, except, with respect to such Prospectus or Permitted Free Writing Prospectus, insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Underwriter furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in, such Prospectus or Permitted Free Writing Prospectus or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in light of the circumstances under which they were made, not misleading.

(b) Each Underwriter severally and not jointly agrees to indemnify, defend and hold harmless the Company, its directors and officers, and any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Company or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Underwriter furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in, the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company), or arises out of or is based upon any omission or alleged omission to state a material fact in such Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Underwriter furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in, a Prospectus or a Permitted Free Writing Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in light of the circumstances under which they were made, not misleading, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectus or a Permitted Free Writing Prospectus furnished on behalf of the Underwriter under the captions “Underwriting—Price Stabilization, Short Positions” and “Underwriting—Commissions and Discounts” (such information being defined as the “Underwriter Information”).

(c) If any action, suit or proceeding (each, a “Proceeding”) is brought against a person (an “indemnified party”) in respect of which indemnity may be sought against the Company or an Underwriter (as applicable, the “indemnifying party”) pursuant to subsection (a) or (b), respectively, of this Section 8, such indemnified party shall promptly notify such indemnifying party in writing of the institution of such Proceeding and such indemnifying party shall, if it so elects, assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify such indemnifying party shall not relieve such indemnifying party from any liability which such indemnifying party may have to any indemnified party pursuant to subsection (a) or (b) above unless such omission results in the forfeiture by the indemnifying party of substantial rights and defenses and shall not, in any event, relieve such indemnifying party from obligations to any indemnified party. The indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such Proceeding or the indemnifying party shall not have, within a reasonable period of time in light of the circumstances, employed counsel to defend such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with those available to such indemnifying party (in which case such indemnifying party shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by such indemnifying party and paid as incurred (it being understood, however, that such indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The indemnifying party shall not be liable for any settlement of any Proceeding effected without its written consent but if settled with its written consent such indemnifying party agrees to indemnify and hold harmless the indemnified party or parties from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this Section 8, then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable to an indemnified party under subsections (a) and (b) of this Section 8 or insufficient to hold an indemnified party harmless in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (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 Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only 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 in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company, and the total underwriting discounts and commissions received by the Underwriters, bear to the aggregate public offering price of the Securities. The relative fault of the Company on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

(e) The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in subsection (d) above. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount equal to the total underwriting discounts and commissions received by such Underwriters. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 8 are several in proportion to their respective underwriting commitments and not joint.

(f) The indemnity and contribution agreements contained in this Section 8 and the covenants, warranties and representations of the Company contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of any Underwriter, its partners, directors or officers or any person (including each partner, officer or director of such person) who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or on behalf of the Company, its directors or officers or any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Securities. The Company and each Underwriter agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Company, against any of their officers or directors in connection with the issuance and sale of the Securities, or in connection with the Registration Statement, any Base Prospectus, any Pre-Pricing Prospectus, the Prospectus or any Permitted Free Writing Prospectus.

9. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all costs, expenses, fees and taxes in connection with (i) the preparation and filing of the Registration Statement, each Base Prospectus, each Pre-Pricing Prospectus, the Prospectus Supplement, the Prospectus, each Permitted Free Writing Prospectus required to be filed and any amendments or supplements thereto, and the printing and furnishing of copies of each thereof to the Underwriters and to dealers (including costs of mailing and shipment), (ii) the registration, authorization, issue, sale and delivery of the Securities including any stock or transfer taxes and stamp or similar duties payable upon the sale, issuance or delivery of the Securities to the Underwriters, (iii) the producing, word processing and/or printing of this Agreement, any agreement among Underwriters, any dealer agreements and any closing documents (including compilations thereof) and the reproduction and/or printing and furnishing of copies of each thereof to the Underwriters and (except closing documents) to dealers (including costs of mailing and shipment), (iv) the qualification of the Securities for offering and sale under Colombian, United States, state or other foreign laws and the determination of their eligibility for investment under Colombian, United States, state or other foreign law (including the legal fees and filing fees and other reasonable disbursements of counsel for the Underwriters) and the printing and furnishing of copies of any blue sky surveys or legal investment surveys to the Underwriters and to dealers, (v) any listing of the Securities on any securities exchange or qualification of the Securities for quotation on the NYSE and any registration thereof under the Exchange Act, (vi) the fees and disbursements of any Depositary, transfer agent or registrar for the Securities (including the fees and expenses of Depositary’s counsel), (vii) the inclusion of the Securities in the book-entry system of DTC, (viii) the rating of the Securities by rating agencies, (ix) the costs and expenses of the Company relating to presentations or meetings undertaken in connection with the marketing of the offering and sale of the Securities to prospective investors and the Underwriters’ sales forces, including, without limitation, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations, travel, lodging and other expenses incurred by the officers of the Company and any such consultants, (x) all the reasonable fees and expenses of the

Underwriters (including, without limitation, reasonable legal fees and expenses of the Underwriters including a U.S. counsel and a local counsel), and (xi) the performance of the Company’s other obligations hereunder.

(b) If (i) this Agreement is terminated pursuant to Section 6, (ii) the Company for any reason fails to tender the Securities for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement, the Company shall not be subject to any obligation or liability under this Agreement; provided, however, that the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby to the extent set forth in Section 9(a) and the Underwriters shall be under no obligation or liability to the Company under this Agreement (except to the extent provided in Section 8 hereof).

The Company further acknowledges that the Underwriters are acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis, and in no event do the parties intend that the Underwriters act or be responsible as a fiduciary to the Company, its management, stockholders or creditors or any other person in connection with any activity that the Underwriters may undertake or have undertaken in furtherance of the purchase and sale of the Company’s securities, either before or after the date hereof. The Underwriters hereby expressly disclaim any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect. The Company and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Underwriters to the Company regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the Company’s securities, do not constitute advice or recommendations to the Company. The Company hereby waives and releases, to the full extent permitted by law, any claims that the Company may have against the Underwriters with respect to any breach or alleged breach of any fiduciary or similar duty to the Company in connection with the

transactions contemplated by this Agreement or any matters leading up to such transactions. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.

17. Counterparts. This Agreement may be signed by the parties in one or more counterparts which together shall constitute one and the same agreement among the parties.

18. Successors and Assigns. This Agreement shall be binding upon the Underwriters and the Company and their respective successors and assigns and any successor or assign of any substantial portion of the Company’s and any of the Underwriters’ respective businesses and/or assets.

19. Amendments or Waivers. No amendment or waiver of any provision of this Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.

20. Foreign Taxes. All payments by the Company to the Underwriters hereunder shall be made free and clear of, and without deduction or withholding for or on account of, any and all present and future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereinafter imposed, levied, collected, withheld or assessed by the government of Colombia or any other jurisdiction from or through which payment is made or deemed to be made, or any political subdivision thereof or therein excluding (i) any such tax imposed by reason of the Underwriters having some present or former connection with any such jurisdiction other than their participation as the Underwriters hereunder, and the receipt of payments hereunder, and (ii) any income or franchise tax on the overall net income of the Underwriters imposed by the United States or by the State of New York or any political subdivision of the United States or of the States of New York (all such non-excluded taxes, “Foreign Taxes”). If the Company is prevented by operation of law or otherwise from paying, causing to be paid or remitting that portion of amounts payable hereunder represented by Foreign Taxes withheld or deducted, then amounts payable under this Agreement shall be increased to such amount as is necessary to yield and remit to the Underwriters an amount that, after withholding or deduction of all Foreign Taxes (including all Foreign Taxes payable on such increased payments) equals the amount that would have been payable if no Foreign Taxes applied.

21. Judgment Currency. The Company agrees to indemnify each Underwriter against any loss incurred by such Underwriter as a result of any judgment or order being given or made for any amount due hereunder and such judgment or order being expressed and paid in a currency (the “Judgment Currency”) other than United States dollars and as a result of any variation as between (i) the rate of exchange at which the United States dollar amount is converted into the Judgment Currency for the purpose of such judgment or order, and (ii) the rate of exchange at which the Underwriter is able to purchase United States dollars, on the nearest business day following the date of judgment, with the amount of the Judgment Currency actually received by the Underwriter. The foregoing indemnity shall constitute a separate and independent obligation of the Company and shall continue in full force and effect

notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, the relevant currency.

22. Miscellaneous.
