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.

For the purposes of this Agreement, the “Applicable Time” is 5:00 p.m. (Eastern time) on the date of this Agreement.

The Company has furnished to you, for use by the Underwriters and by dealers in connection with the offering of the Notes, copies of one or more preliminary prospectus supplements, and the documents incorporated by reference therein, relating to the Notes.

(b) Each Underwriter severally 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 caption Underwriting in the third sentence of the third paragraph and the fourth and sixth paragraphs (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 any obligations to any indemnified party (other than the indemnification obligation provided in paragraph (a) or (b) above). 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(c), 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 Notes 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 Notes. 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 Notes. 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 Notes, or in connection with the Registration Statement, any Base Prospectus, any Pre-Pricing Prospectus, the Prospectus or any Permitted Free Writing Prospectus.

13. Parties at Interest.

14. No Fiduciary Relationship. The Company hereby acknowledges that the Underwriters are acting solely as underwriters in connection with the purchase and sale of the Company’s securities.

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.

17. 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 the Republic 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.

Ladies and Gentlemen:

In connection with the several purchases today by you pursuant to the Underwriting Agreement, dated July [•], 2010 (the “Underwriting Agreement”), between Bancolombia S.A., a financial institution incorporated under the laws of the Republic of Colombia as a sociedad anónima (the “Bank”), and you, of U.S. $[•] aggregate principal amount of the Bank’s [•]% Subordinated Notes due 2020 (the “Notes”), issued pursuant to the Indenture, dated as of July [•], 2010 (the “Indenture”), between the Bank and The Bank of New York Mellon, as trustee (“Trustee”) (the Underwriting Agreement, the Indenture and the Notes together the “Opinion Documents”), we, as special United States counsel for the Bank, have examined such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion. Upon the basis of such examination, it is our opinion that:

(1) the Underwriting Agreement has been duly executed and delivered by the Bank.

the Indenture has been duly executed and delivered by the Bank, has been duly qualified under the Trust Indenture Act of 1939 and constitutes a valid and legally binding obligation of the Bank enforceable against it in accordance with its terms.

the Notes have been duly executed, authenticated and delivered and constitute valid and legally binding obligations of the Bank enforceable against it in accordance with their terms.

(4) All regulatory consents, authorizations, approvals and filings required to be obtained or made by the Bank under the Covered Laws for the execution and delivery by the Bank of the Opinion Documents and the issuance and sale of the Notes by the Bank, have been obtained or made.

Ex. A-1

(5) The Bank is not, and after giving effect to the offering and sale of the Notes and the application of the proceeds thereof as described in the Prospectus Supplement dated July [•], 2010 under the caption “Use of proceeds” will not be, required to be registered as an “investment company” under the Investment Company Act of 1940, as amended.

(6) The issuance of the Notes in accordance with the Indenture and the sale of the Notes by the Bank to you pursuant to the Underwriting Agreement do not, and the performance by the Bank of its obligations under the Opinion Documents will not, violate any Covered Laws applicable to the Bank.

(7) Under the laws of the State of New York relating to submission to personal jurisdiction, the Bank has, pursuant to Section 12 of the Underwriting Agreement and 11.10 of the Indenture, validly and irrevocably submitted to the personal jurisdiction of any court of the State of New York, located in the City and County of New York or the United States District Court for the Southern District of New York, in any suit or proceeding arising out of or relating to the Underwriting Agreement, the Indenture or the transactions contemplated thereby, has validly and irrevocably waived, to the fullest extent it may effectively do so, any objection to the venue of a proceeding in any such court, has, pursuant to Section 11 of the Underwriting Agreement and 11.10 of the Indenture, validly and irrevocably appointed CT Corporation System in New York as its authorized agent for service of process, and service of process effected on such agent in the manner set forth in the Underwriting Agreement and Indenture and otherwise in accordance with applicable law will be effective to confer valid personal jurisdiction over the Bank in any such action, in each case, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles, and assuming (a) the due authorization, execution and delivery of the Underwriting Agreement by the underwriters named therein and the Indenture by the Trustee and (b) the validity and effectiveness of such actions insofar as the laws of the Republic of Colombia are concerned.

(8) The execution and delivery by the Company of the Opinion Documents do not, and the performance by the Company of its obligations under the Opinion Documents will not violate the Deposit Agreement between the Bank and Bank of New York Mellon, as Depositary, relating to the American Depositary Shares of the Bank, which agreement is listed as an exhibit to the Bank’s most recent Annual Report on Form 20-F filed with the Securities and Exchange Commission.

We are expressing no opinion in paragraphs (2), (3) and (6) above, insofar as performance by the Company of its obligations under any Opinion Document is concerned, as to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights. Also, for purposes of the opinions in paragraphs (4) and (6) above, “Covered Laws” means the federal laws of the United States and the laws of the State of New York (including the published rules or regulations thereunder) that in our experience normally are applicable to general business corporations and transactions such as those contemplated by the Opinion Documents; provided further, that such term does not include Federal or state securities laws, other antifraud laws and fraudulent transfer laws, tax laws, the Employee Retirement Income Security Act of 1974, antitrust laws or any law that is applicable to the Company, the Opinion Documents or the transactions contemplated thereby solely as part of a regulatory regime applicable to the Bank or its affiliates due to its or their status, business or assets.

Ex. A-2

In connection with our opinion set forth in paragraph (7) above, we assume that any such action will be properly brought in a court having jurisdiction over the subject matter, and we are expressing no opinion with respect to the subject matter jurisdiction of any such court. Also, we are expressing no opinion as to whether or under what circumstances such a court might decline to accept jurisdiction over such action on the ground that New York is an inconvenient forum. Furthermore, we express no opinion with respect to the provisions of Section 11 of the Underwriting Agreement and 11.10 of the Indenture insofar as it relates to (i) the subject matter jurisdiction of any United States Federal court to adjudicate any controversy, (ii) the jurisdiction of any courts other than the courts of the State of New York and United States Federal courts, (iii) the conclusiveness or enforceability of foreign judgments, or (iv) the waiver of inconvenient forum with respect to proceedings in the United States District Court for the Southern District of New York.

The foregoing opinion is limited to the federal laws of the United States and the laws of the State of New York, and we are expressing no opinion as to the effect of the laws of any other jurisdiction. We have, with your approval, assumed that the Bank has been duly incorporated and is validly existing as a sociedad anónima in good standing under the laws of the Republic of Colombia, and that any document referred to in this opinion and executed by the Bank has been duly authorized, executed and delivered insofar as the laws of the Republic of Colombia are concerned and is valid, binding and enforceable under the laws of the Republic of Colombia. With respect to all matters of Colombian law, we understand that you are relying upon the opinion, dated July [•], 2010, of ▇▇▇▇▇-▇▇▇▇▇▇ ▇▇▇▇▇▇ Abogados S.A. delivered to you pursuant to Section 6(b) of the Underwriting Agreement.

We have also relied as to certain matters upon information obtained from public officials, officers of the Bank and other sources believed by us to be responsible, and we have assumed that the Indenture has been duly authorized, executed and delivered by the Trustee, that the Notes conform to the specimen thereof examined by us, that the Trustee’s certificates of authentication of the Notes have been manually signed by one of the Trustee’s authorized officers, and that the signatures on all documents examined by us are genuine, assumptions which we have not independently verified.

Very truly yours,

Ladies and Gentlemen:

[This is with reference to the registration under the Securities Act of 1933 (the “Securities Act”) and offering of $[•] aggregate principal amount of [•]% Subordinated Debt Securities due 2020 (the “Notes”) of Bancolombia S.A., a financial institution incorporated under the laws of the Republic of Colombia as a sociedad anónima (the “Bank”).

The Registration Statement relating to the Notes (File No. [•]) was filed on Form F-3 in accordance with procedures of the Securities and Exchange Commission (“Commission”) permitting a delayed or continuous offering of securities pursuant thereto and, if appropriate, a post-effective amendment, document incorporated by reference therein or prospectus supplement that provides information relating to the terms of the securities and the manner of their distribution. The Notes have been offered by the Prospectus, dated July [•], 2010 (the “Basic Prospectus”), as supplemented by the Prospectus Supplement, dated July [•], 2010 (the “Prospectus Supplement”), which updates or supplements certain information contained in the Basic Prospectus. The Basic Prospectus, as supplemented by the Prospectus Supplement, does not necessarily contain a current description of the Bank’s business and affairs since, pursuant to Form F-3, it incorporates by reference certain documents filed with the Commission that contain information as of various dates.

As special United States counsel to the Bank, we reviewed the Registration Statement, the Basic Prospectus, the Prospectus Supplement and the documents listed in Schedule A (those listed documents, taken together with the Basic Prospectus, being referred to herein as the “Pricing Disclosure Package”) and participated in discussions with your representatives, your United States and Colombian counsel and representatives of the Bank, its accountants and its Colombian counsel. In addition, we reviewed opinions addressed to you from the Bank’s Colombian counsel regarding certain portions of the Basic Prospectus, the Prospectus Supplement and the Pricing Disclosure Package. Between the date of the Prospectus Supplement and the time of delivery of this letter, we participated in further discussions with your representatives, your United States and Colombian counsel and representatives of the Bank, its accountants and its Colombian counsel, concerning certain matters relating to the Bank and reviewed certificates of certain officers of the Bank, letters addressed to you from the Bank’s accountants and opinions addressed to you from the Bank’s Colombian counsel.

Ex. A-4

On the basis of the information that we gained in the course of the performance of the services referred to above, considered in the light of our understanding of the applicable law (including the requirements of Form F-3 and the character of prospectus contemplated thereby) and the experience we have gained through our practice under the Securities Act, we confirm to you that, in our opinion, the Registration Statement, as of the date of the Prospectus Supplement, and the Basic Prospectus, as supplemented by the Prospectus Supplement, as of the date of the Prospectus Supplement, appeared on their face to be appropriately responsive, in all material respects relevant to the offering of the Notes, to the requirements of the Securities Act, the Trust Indenture Act of 1939 and the applicable rules and regulations of the Commission thereunder. Also, we confirm to you that the statements contained in the Registration Statement, the Basic Prospectus, the Prospectus Supplement and the Pricing Disclosure Package under the caption “Description of Debt Securities” in the Basic Prospectus and under the captions “Description of the notes” and “Underwriting” in the Prospectus Supplement, in each case insofar as they relate to provisions of the Notes the Indenture under which the Notes are being issued and the underwriting agreement between you and the company regarding the purchase and sale of the Notes, and the statements contained under the caption “United States Taxation” in the Prospectus Supplement, insofar as such statements relate to provisions of United States federal income tax law, constitute a fair and accurate summary of such provisions in all material respects. Further, nothing that came to our attention in the course of such review has caused us to believe that, insofar as relevant to the offering of the Notes,

(a) the Registration Statement, as of the date of the Prospectus Supplement, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading, or

(b) the Pricing Disclosure Package, as of [•]p.m. on July [•], 2010, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

(c) the Basic Prospectus, as supplemented by the Prospectus Supplement, as of the date of the Prospectus Supplement, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

We also advise you that nothing that came to our attention in the course of the procedures described in the second sentence of this paragraph has caused us to believe that the Basic Prospectus, as supplemented by the Prospectus Supplement, as of the time of delivery of this letter, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

We confirm to you that, based solely upon a telephonic confirmation from a representative of the Commission on the date hereof, the Registration Statement is effective under the Securities Act and no stop order had been issued as of the time of such telephone conversation. In addition, we do not know of any litigation or any governmental proceeding instituted or threatened against the Company that would be required to be disclosed in the Basic Prospectus, as supplemented by the Prospectus Supplements, and is not so disclosed. Also, we do not know of any documents that are required to be filed as exhibits to the Registration Statements and are not so filed.

Ex. A-5

The limitations inherent in the independent verification of factual matters and the character of determinations involved in the registration process are such, however, that we do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Pricing Disclosure Package, except to the extent specifically noted in the second sentence of the second preceding paragraph. Also, we do not express any opinion or belief as to the financial statements or other financial data derived from accounting records contained in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Pricing Disclosure Package, as to the report of management’s assessment of the effectiveness of internal control over financial reporting or the auditors’ attestation report thereon, each as included in the Registration Statement, the Basic Prospectus, the Prospectus Supplement, or the Pricing Disclosure Package, or as to the statement of the eligibility of the Trustee under the Indenture under which the Notes are being issued.

This letter is furnished by us, as special United States counsel to the Bank, to the Underwriters, solely for the benefit of the Underwriters in their capacity as such, and may not be relied upon by any other person. This letter may not be quoted, referred to or furnished to any purchaser or prospective purchaser of the Notes and may not be used in furtherance of any offer or sale of the Notes.]

Ladies and Gentlemen:

[We have acted as special Colombian counsel to Bancolombia S.A., a Colombian financial institution organized and existing as a sociedad anónima under the laws of the Republic of Colombia (the “Company”), in connection with the Company’s offering of U.S. $[●] [●]% subordinated notes due 2020 (the “Notes”) issued pursuant to the Indenture dated ______, between the Company and the Bank of New York Mellon, as trustee (the “Trustee”).

This opinion is delivered to you pursuant to Section 6(b) of the Underwriting Agreement (the “Underwriting Agreement”) entered into by the Company with you as underwriters (collectively, the “Underwriters”), dated ______, 2010.

In stating our opinion, we have assumed the genuineness of all signatures on original or certified copies, the authenticity of documents submitted to us as originals and the conformity to original or certified copies, of all copies submitted to us as certified or reproduction copies. We have also assumed, for the purposes of the opinions expressed herein, that each of the parties to the Underwriting Agreement and the Indenture, other than the Company, has the corporate power and authority to enter into and perform each of the Underwriting Agreement and the Indenture and that the Underwriting Agreement and the Indenture have been duly authorized, executed and delivered by such party. Also, we have examined such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion.

Capitalized terms used herein without definition shall have the respective meanings ascribed to them in the Underwriting Agreement.

Based upon the foregoing, we are of the opinion that:

1 NTD: Comments to follow

Ex. B-1

(i) The Company has been duly incorporated and is validly existing as a sociedad anónima under the laws of the Republic of Colombia, with full corporate power and authority to own, lease and operate its properties and conduct its business as described in the Registration Statement, the preliminary prospectus supplement of the Company, dated [●], 2010, relating to the Notes (including the base prospectus attached thereto and the documents incorporated by reference therein, the “Pre-Pricing Prospectus”), the Prospectus and the Disclosure Package (including any Permitted Free Writing Prospectuses attached hereto as Annex A) to execute and deliver the Underwriting Agreement and to perform its obligations thereunder, including, without limitation, to issue, sell and deliver the Notes as contemplated by the Underwriting Agreement.

(ii) The Company is duly qualified to do business as a foreign corporation in each jurisdiction where the ownership or leasing of its respective properties or the conduct of its businesses requires such qualification, except where the failure to be so qualified would not, individually or in the aggregate, have a Material Adverse Effect.

(iii) The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

(iv) The Notes have been duly and validly authorized and executed and, assuming the due authentication of the Notes by the Trustee and assuming that the Notes constitute valid and legally binding obligations under the laws of the State of New York, upon authentication by the Trustee and delivery by the Company against payment therefor by the Underwriters in accordance with the terms of the Underwriting Agreement and the Indenture, the Notes will be legally binding and valid obligations of the Company, entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms, except as the enforcement thereof may be limited by the Bankruptcy Exceptions.

(v) The Notes qualify as Tier Two Capital pursuant to the relevant Colombian laws.

(vi) The Indenture has been duly and validly authorized, executed and delivered by the Company and, assuming the due authorization, execution and delivery thereof by the Trustee and assuming that the Indenture constitutes valid and legally binding obligations under the laws of the State of New York, the Indenture is a legally binding and valid obligation of the Company, enforceable against it in accordance with its terms, except as the enforcement thereof may be limited by the Bankruptcy Exceptions.

(vii) No approval, authorization, consent or order under any laws of Colombia or approval, authorization, consent of or filing with any Colombian governmental or regulatory commission, board, body, authority or agency is required in connection with the execution, delivery and performance by the Company of the Underwriting Agreement, the Indenture and the Notes or with the consummation by the Company of the transactions contemplated by the Underwriting Agreement.

(viii) The execution, delivery and performance of the Underwriting Agreement and the Indenture by the Company, the issuance and sale of the Notes, the consummation of the transactions contemplated by the Underwriting Agreement and the application of the proceeds thereof as described in the Prospectus Supplement under the heading “Use of Proceeds” do not and will not result in any breach or violation of or constitute a default under, nor constitute any event which, with notice, lapse of time or both, would result in any breach or violation of or constitute a default under or give the holder of any indebtedness or a person acting on such holder’s behalf, the right to require the repurchase, redemption or repayment of all or a part of such indebtedness under, or result in the creation or imposition of a lien, charge or encumbrance on any property or assets of the Company pursuant to: (i) the charter or bylaws of the Company, or (ii) Colombian laws, or (iii) any decree, judgment or order applicable to the Company or any of its respective properties, which decree, judgment or order is known by us.

Ex. B-2

(ix) To our knowledge, (i) the Company is not a party to any legal or governmental action or proceeding that challenges the validity or enforceability, or seeks to enjoin the performance, of the Underwriting Agreement; and (ii) there are no actions, suits, claims, investigations or proceedings pending, threatened or contemplated to which the Company or any of its directors or officers is or would be a party or to which any of its properties is or would be subject at law or in equity, before or by any federal, state, local or foreign governmental or regulatory commission, board, body, authority or agency which are required to be described in the Registration Statement, the Pre-Pricing Prospectus or the Prospectus but are not so described as required.

(x) The statements in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus under the headings “Enforcement of civil liabilities against foreign persons,” “Summary – the Offering,” “Risk factors,” “Colombian banking regulations,” “Description of the Notes,” and “Tax Considerations – Colombian Tax Considerations,” in each case insofar as such statements constitute summaries of Colombian legal matters or documents referred to therein, fairly summarize the information purported to be shown.

(xi) Subject to the qualifications set forth below, the choice of law of the State of New York as the governing law of the Underwriting Agreement, the Indenture and the Notes is a valid choice of law under the laws of Colombia, and the courts of Colombia will honor this choice of law. The irrevocable submission of the Company to the jurisdiction of the courts specified in the Underwriting Agreement, the Indenture and the Notes, the waiver by the Company of any objection to the venue of such specified courts, and the appointment of CT Corporation System as the agent for service of process in any suit or proceeding based on or arising under each of the Underwriting Agreement, the Indenture and the Notes in any federal or state court in the State of New York, is valid and enforceable under Colombian law and would be recognized by the courts of Colombia. A final and conclusive judgment (not subject to appeal) of the courts of the State of New York for the payment of money rendered against the Company in respect of the Underwriting Agreement, the Indenture and the Notes, would be recognized by the courts of Colombia.

(xii) The Company and its respective assets are subject to suit in Colombia and neither the Company nor its assets have any right of immunity, on the grounds of sovereignty or otherwise, from any legal action, suit or proceeding in Colombia.

(xiii) No Colombian stamp, registration, documentary or other issuance or transfer taxes or duties and no capital gains, income, withholding or other taxes or duties are payable by or on behalf of the Underwriters to Colombia or any political subdivision or taxing authority thereof or therein in connection with the sale and delivery by the Company of the Notes to the Underwriters or the sale and delivery by the Underwriters of the Notes as contemplated in the Underwriting Agreement.

(xiv) Except as set forth, and subject to the conditions provided in the Disclosure Package, and provided that the holders of the Notes are not Colombian residents for tax purposes, there is no tax, impost, deduction, or withholding imposed by Colombia or by any political subdivision or taxing authority thereof or therein on any payment to be made by the Company pursuant to the Notes.

Ex. B-3

(xv) It is not necessary under the laws of Colombia, in order to enable the Underwriters, the Trustee or the holders of the Notes, to enforce any of their rights under the Underwriting Agreement, the Indenture or the Notes, that the Underwriters, the Trustee or the holders of the Notes, should be licensed, qualified or entitled to carry on business in Colombia.

(xvi) Assuming that each of the Underwriting Agreement, the Indenture and the Notes are executed and delivered outside of Colombia, none of the Underwriters, the Trustee or the holders of the Notes will be deemed residents or subject to taxation in Colombia, by virtue solely of the execution or performance of the Underwriting Agreement, the Indenture or the Notes, assuming that none of such persons is domiciled or a resident of Colombia for tax purposes.

This opinion is subject to the following qualifications.

(i) Under the laws of Colombia, the choice of the law of the State of New York as governing law would be recognized subject to the proof of the provisions of the applicable law of the State of New York in the manner provided for in such proceedings in Colombia. In any proceeding in Colombia to enforce a document subject to the law of the State of New York, the court would interpret the provisions of such document by reference to law of the State of New York provided that the provisions of law of the State of New York do not violate the public order Laws of Colombia.

(ii) The courts of Colombia would give effect to and enforce a final judgment rendered by any court of the State of New York or any courts outside of Colombia through a procedural system provided for under Colombian law known as “exequatur”, subject to the provisions of Article 693 of the Colombian Code of Civil Procedure which requires that there be reciprocity in the recognition of foreign judgments between the courts of the relevant jurisdiction and the courts of Colombia and subject to compliance with provisions of Article 694 of the Colombian Code of Civil Procedure. The pertinent provisions of such articles as they would affect a judgment obtained in a foreign court are as follows: (a) the foreign judgment presented in Colombia for enforcement does not conflict with public order laws of Colombia, other than Laws governing procedure; (b) the foreign judgment, in accordance with the laws of the country where it was rendered, is final and a duly certified and authenticated copy has been presented to the court in Colombia; (c) no proceedings are pending in Colombia with respect to the same cause of action and no final judgment has been awarded in Colombia in any proceeding on the same subject matter and between the same parties; (d) in the proceedings commenced in the foreign court which issued the judgment, the defendant was served process in accordance with the law of such jurisdiction and in a manner reasonably designed to give an opportunity to the defendant for the defense of the action; and (e) the judgment obtained in a foreign court will not adjudicate property rights (in rem rights) over assets located in Colombia at the time of commencement of the proceeding pursuant to which such judgment was obtained. Proceedings for execution of a money judgment by attachment or execution against any assets or property located in Colombia would be within the exclusive jurisdiction of Colombian courts. Bankruptcy proceedings, composition, liquidation, creditor’s arrangements proceedings, annulment of corporate resolutions, repossession, and proceedings in connection with “in rem” actions over assets located in Colombia would also be within the exclusive jurisdiction of Colombian courts.

Ex. B-4

(iii) The United States and Colombia do not have any bilateral treaty providing for reciprocal recognition and enforcement of judgments in civil and commercial matters, but the Supreme Court of Colombia has accepted that reciprocity exists when it has been proven either that a United States court has enforced a Colombian judgment or that a United States court would enforce a foreign judgment including a judgment issued by a Colombian court.

(iv) The enforcement of the Underwriting Agreement, the Indenture and the Notes may be limited: (a) by applicable laws relating to the enforcement of creditors’ rights generally, and any proceeding for enforcement in Colombia would be subject to the applicable limitation on actions by prescription, limiting the period for commencement for actions in Colombia; (b) articles 823 of the Colombian Code of Commerce and 260 of the Colombian Code of Civil Procedure pursuant to which any proceeding in Colombia requires that a translation into Spanish be the basis for enforcement, in any event of a disagreement over the meaning of the translation, the official Spanish translation will govern rather than the original English text for purposes of such proceeding; (c) applicable laws pursuant to which indemnification provisions are not enforceable if there has been gross negligence or willful misconduct from the indemnified party; and (d) in any proceeding filed, commenced or brought to a court in Colombia, service of notice to the parties will be made in accordance with the provisions of the Colombian Code of Civil Procedure and contractual provisions regarding service of process will not be enforceable.

(v) Furthermore, we express no opinion as to whether a court in any proceeding in Colombia would give effect to certain provisions that may be limited by: (i) applicable procedural rules that do not allow waivers of immunity and service of process by private companies within Colombia and pursuant to which any immunity from proceedings (jurisdiction, execution or attachment) which might in the future be available under Colombian law may not be validly waived in advance; and (ii) the unavailability under Colombian law of equitable remedies or injunctive relief, except for fundamental constitutional rights.

We are licensed to practice law in Colombia and we do not hold ourselves out as being conversant with, and express no opinion as to, the laws of any jurisdiction other than those of Colombia. In particular, to the extent that New York or United States Federal law is relevant to this opinion, we have relied, without any independent investigation, on the opinion of ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, special U.S. legal counsel to the Company, delivered to you pursuant to Section 6(a) of the Underwriting Agreement, and our opinion is subject to the same assumptions, qualifications and limitations with respect to such matters as are contained in such opinion of ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP. This opinion is limited to matters of Colombian law.

We are furnishing this letter to you solely for your benefit in connection with the offering of the Notes. This opinion is solely for your benefit and may not be relied upon in any manner or any purpose by any other person.]

Ladies and Gentlemen:

[This is with reference to the registration under the Securities Act of 1933 (the “Securities Act”) and offering of offering of U.S. $[●] [●]% subordinated notes due 2020 (the “Notes”) issued pursuant to the Indenture dated ______, between the Company and the Bank of New York Mellon, as trustee (the “Trustee”), by Bancolombia S.A., a Colombian financial institution organized and existing as a sociedad anónima under the laws of the Republic of Colombia (the “Company”). The Notes have been offered by the Prospectus, dated ______, 2010 (the “Basic Prospectus”), as supplemented by the Prospectus Supplement, dated _____, 2010 (the “Prospectus Supplement”), which updates or supplements certain information contained in the Basic Prospectus.

As special Colombian counsel of the Company, we reviewed the Registration Statement, the Basic Prospectus, the Prospectus Supplement and the documents listed in Annex A (those listed documents, taken together with the Basic Prospectus, and the Prospectus Supplement being referred to herein as the “Disclosure Package”).

This letter is delivered to you pursuant to Section 6(b) of the Underwriting Agreement (the “Underwriting Agreement”) entered into by the Company with you as underwriters (collectively, the “Underwriters”), dated ______, 2010.

Capitalized terms used herein without definition shall have the respective meanings ascribed to them in the Underwriting Agreement.

Because the primary purpose of our professional engagement was not to establish or confirm factual matters or financial or accounting information, and because many determinations involved in the preparation of the Disclosure Package are of a wholly or partially non-legal character or relate to legal matters outside the scope of our opinion letter to you of even date herewith, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Disclosure Package, except with respect to the statements in the Basic Prospectus and the Prospectus Supplement under the headings “Enforcement of civil liabilities against foreign persons,” “Summary – Recent developments,” “Risk factors,” “Colombian banking regulations,” “Tax considerations – Colombian Tax Considerations,” in each case insofar as such statements constitute summaries of Colombian legal matters or documents referred to therein.

Ex. B-6

In the course of our acting as Colombian counsel to the Company, we have participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants of the Company and representatives of the Underwriters at which the contents of the Registration Statement and the Disclosure Package were discussed and, although we are not passing upon and do not assume responsibility for the accuracy, completeness or fairness of the statements contained in the Disclosure Package (except as stated in the paragraph above), on the basis of the foregoing, nothing has come to our attention that causes us to believe that (i) the Registration Statement, at the Effective Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Disclosure Package, as of the Applicable Time (as defined below), included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) the Prospectus, as supplemented by the Prospectus Supplement, as of the date of the Prospectus Supplement or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that we express no opinion with respect to the financial statements and schedules, and other financial data derived therefrom, included in the Registration Statement, or the Disclosure Package).

As used herein, “Applicable Time” means [●], New York City time, on [●], 2010.

We are furnishing this letter to you solely for your benefit in connection with the offering of the Notes. This letter is solely for your benefit and may not be relied upon in any manner or any purpose by any other person. This letter may not be quoted, referred to or furnished to any purchaser or prospective purchaser of the Securities and may not be used in furtherance of any offer or sale of the Securities.]
