(iv) to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement or any notice that would prevent its use has been issued, and no proceedings for that purpose have been instituted or threatened;

(a) In addition to any other remedies which may be available to the Underwriters, the Underwriters (or any of them) shall be entitled, at their option, to terminate and cancel, without any liability on the Underwriters’ part, their obligations under this Agreement to purchase the Units and any Additional Securities, by giving written notice to the Corporation at any time at or prior to the Closing Time on the Closing Date if at any time prior to the closing of the Offering:

(i) the state of the financial markets in Canada or elsewhere where it is planned to market the Units, or the industry or state of the markets in which the Corporation operates, is such that, in the reasonable opinion of the Underwriters (or any of them), the Units cannot be marketed profitably; or

(ii) there shall have occurred any adverse material change in relation to the Corporation, or there should be a previously undisclosed material adverse change (whether actual, proposed or prospective) which is discovered or required to be disclosed, or there should occur a change in a material fact contained in the disclosure of the Corporation, or in the Offering Documents that in the reasonable opinion of the Underwriters (or any of them), has or would be expected to result in a Material Adverse Effect or have a significant adverse effect on the market price or value of the Units and/or the Common Shares and/or Warrants; or

(iii) any inquiry, investigation or other proceeding (whether formal or informal) is made or any order is issued under or pursuant to any statute of Canada or any province thereof or any statute of the United States or any

state thereof or any other jurisdiction to which the Corporation or any of its Subsidiaries is subject or any stock exchange in relation to the Corporation or any of its securities (except for any inquiry, investigation or other proceeding or order based upon the activities of the Underwriters and not upon activities of the Corporation), which, in the opinion of the Underwriters (or any of them), acting reasonably, prevents or restricts trading in or the Distribution of the Common Shares and/or Warrants or significantly adversely affects the market price of the Units or the business, operations or affairs of the Corporation and its Subsidiaries, taken as a whole; or

(iv) there should develop, occur or come into effect or existence any event, action, state, condition or major financial occurrence of national or international consequence, including, without limiting the generality of the foregoing, any military conflict, civil insurrection, or any terrorist action (whether or not in connection with such conflict or insurrection), or any law or regulation (or change in the interpretation or administration thereof) which, in the opinion of the Underwriters (or any of them) seriously adversely affects, or involves, or will seriously adversely affect or involve, the financial markets or the business, operations or affairs of the Corporation and its subsidiaries, taken as a whole, and/or prevent or materially restrict the trading in or the Distribution of the Units, the Common Shares and/or Warrants; or

(b) The Corporation agrees that all material terms and conditions of this Agreement shall be construed as conditions and complied with so far as they relate to acts to be performed or caused to be performed by it, that it will use its commercially reasonable best efforts to cause such conditions to be complied with, and that any breach or failure by the Corporation to comply with any such conditions shall entitle any of the Underwriters to terminate their obligations to purchase the Units by notice to that effect given to the Corporation at or prior to the Closing Time, unless otherwise expressly provided in this Agreement. The Underwriters may waive, in whole or in part, or extend the time for compliance with, any terms and

conditions without prejudice to their rights in respect of any other of such terms and conditions or any other or subsequent breach or non-compliance, provided that any such waiver or extension shall be binding upon the Underwriters only if such waiver or extension is in writing and signed by all of the Underwriters.

(c) The Underwriters shall make reasonable best efforts to give notice to the Corporation (in writing or by other means) of the occurrence of any of the events referred to in paragraphs (a) or (b) of this Section 11, provided that neither the giving nor the failure to give such notice shall in any way affect the entitlement of the Underwriters to exercise this right at any time prior to or at the Closing Time.

(i) any statement (except for statements furnished by and relating solely to the Underwriters specifically for use in the Preliminary Prospectuses, Final Prospectuses, the Registration Statement, any Free Writing Prospectus, Issuer Free Writing Prospectus, or Supplementary Material, as identified by the Underwriters to the Corporation in writing on the date hereof) contained in the Offering Documents (including, for greater certainty, in any Documents Incorporated by Reference) or any Issuer Free Writing Prospectus (taken together with the Disclosure Package), which at the time and in the light of the circumstances under which it was made

contains or is alleged to contain a misrepresentation or any misstatement of material fact; or

(ii) the omission or alleged omission to state in the Offering Documents (including, for greater certainty, in any Documents Incorporated by Reference) or any Issuer Free Writing Prospectus (taken together with the Disclosure Package), or any certificate of the Indemnifier delivered hereunder or pursuant hereto, any material fact (except for any material fact contained in the statements furnished by and relating solely to the Underwriters specifically for use in the Preliminary Prospectuses, Final Prospectuses, the Registration Statement, any Free Writing Prospectus, Issuer Free Writing Prospectus, or Supplementary Material, as identified by the Underwriters to the Corporation in writing on the date hereof) required to be stated therein or necessary to make any statement therein not misleading; or

(iii) any order made, or inquiry, investigation or proceeding commenced by any securities regulatory authority or other competent authority based upon any misrepresentation, untrue statement or omission or alleged untrue statement or omission in the Offering Documents (including, for greater certainty, in any Documents Incorporated by Reference) or any Issuer Free Writing Prospectus (taken together with the Disclosure Package), (except for statements furnished by and relating solely to the Underwriters specifically for use in the Preliminary Prospectuses, Final Prospectuses, the Registration Statement, any Free Writing Prospectus, Issuer Free Writing Prospectus, or Supplementary Material, as identified by the Underwriters to the Corporation in writing on the date hereof) that prevents or restricts the trading in any of the Indemnifier’s securities or the Distribution of any of the Units or Additional Securities in any of the Qualifying Provinces or the United States or any other jurisdiction in which they are offered; or

(iv) the Indemnifier not complying with any requirement of Canadian Securities Laws or U.S. Securities Laws or stock exchange requirements in connection with the transactions herein contemplated, including without limitation, the Indemnifier’s non-compliance with any statutory requirement to make any document available for inspection; or

(v) any breach of a representation or warranty of the Indemnifier contained in this Agreement or the failure of the Indemnifier to comply with any of its obligations hereunder.

(b) If any matter or thing contemplated by this Section shall be asserted against any Indemnified Party in respect of which indemnification is or might reasonably be considered to be provided, such Indemnified Party will notify the Indemnifier as soon as possible of the nature of such claim (provided that omission to so notify the Indemnifier will not relieve the Indemnifier of any liability that it may

otherwise have to the Indemnified Party hereunder, except to the extent the Indemnifier is materially prejudiced by such omission) and the Indemnifier shall be entitled (but not required) to assume the defence of any suit brought to enforce such claim; provided, however, that the defence shall be through legal counsel reasonably acceptable to such Indemnified Party and that no admission of liability or settlement may be made by the Indemnifier or such Indemnified Party without the prior written consent of the other, such consent not to be unreasonably withheld.

(c) In any such claim, such Indemnified Party shall have the right to retain other legal counsel to act on such Indemnified Party’s behalf, provided that the fees and disbursements of such other legal counsel shall be paid by such Indemnified Party, unless: (i) the Indemnifier and such Indemnified Party mutually agree to retain other legal counsel; or (ii) the representation of the Indemnifier and such Indemnified Party by the same legal counsel would, in the opinion of such counsel, be inappropriate due to actual or potential differing interests, or (iii) the Indemnifier has not assumed the defence of the action within a reasonable period of time after receiving notice of the claim, or (iv) there are one or more defences available to the Indemnified Party which are different from or in addition to those available to the Indemnifier; in which event such fees and disbursements shall be paid by the Indemnifier to the extent that they have been reasonably incurred, provided that in no circumstances will the Indemnifier be required to pay the fees and expenses of more than one set of legal counsel for all Indemnified Parties.

(d) To the extent that any Indemnified Party is not a party to this Agreement, the Underwriters shall obtain and hold the right and benefit of this Section in trust for and on behalf of such Indemnified Party.

(e) The Indemnifier hereby consents to personal jurisdiction, service and venue in any court in which any claim that is subject to indemnification hereunder is brought against the Underwriters or any Indemnified Party and to the assignment of the benefit of this Section to any Indemnified Party for the purpose of enforcement provided that nothing herein shall limit the Indemnifier’s right or ability to contest the appropriate jurisdiction or forum for the determination of any such claims.

(f) The rights of indemnity contained in this Section shall not enure to the benefit of any Indemnified Party in respect of a particular claim if the Underwriters were provided with a copy of any amendment or supplement to the Offering Documents which corrects any untrue statement or omission or alleged omission that is the basis of that claim by a party against such Indemnified Party and that is required, under the Canadian Securities Laws and/or U.S. Securities Laws, to be delivered to such party by the Underwriters.

(g) The rights accorded to the Indemnified Parties hereunder will be in addition to any rights an Indemnified Party may have at common law or otherwise.

(h) The Indemnifier agrees to reimburse the Underwriters monthly for the time spent by the Underwriters’ personnel in connection with any Claim at their normal per diem rates.

13. CONTRIBUTION

In the event that the indemnity provided for in Section 12 of this Agreement is unavailable for any reason (other than in accordance with the terms hereof) to the Indemnified Parties (or any of them) or is insufficient to hold them harmless, the Corporation will contribute to the amount paid or payable by the Indemnified Parties as a result of such Claims in such proportion as is appropriate to reflect not only the relative benefits received by the Corporation or the Corporation’s shareholders on the one hand and the Indemnified Parties on the other, but also the relative fault of the parties and other equitable considerations which may be relevant. Notwithstanding the foregoing, the Corporation will in any event contribute to the amount paid or payable by the Indemnified Parties as a result of such Claim any amount in excess of the fees actually received by any Indemnified Parties hereunder. Notwithstanding the foregoing, a person guilty of fraudulent misrepresentation or gross negligence or wilful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment) shall not be entitled to contribution from any other party.

14. SEVERABILITY

If any provision of this Agreement is determined by a court of competent jurisdiction to be void or unenforceable in whole or in part, it shall be deemed not to affect or impair the validity of any other provision of this Agreement and such void or unenforceable provision shall be severed from this Agreement.

15. EXPENSES

(c) No action taken pursuant to this Section 17 shall relieve any defaulting Underwriter from liability in respect of its default to the Corporation or to any non-defaulting Underwriter.

The Corporation agrees that it will not claim that the Underwriters owe an agency, fiduciary or

similar duty to the Corporation, in connection with such transaction or the process leading thereto.

21. SURVIVAL

All warranties, representations, covenants and agreements herein contained or contained in documents submitted or required to be submitted pursuant to this Agreement shall survive the purchase by the Underwriters of the Units and any Additional Securities and shall continue in full force and effect, regardless of the closing of the sale of the Units and any Additional Securities and regardless of any investigation which may be carried on by the Underwriters, or on their behalf. Without any limitation of the foregoing, the provisions contained in this Agreement in any way related to the indemnification or the contribution obligations shall survive and continue in full force and effect, indefinitely.

(18) There are no documents required to be filed, no proceedings needed to be taken and no approvals, permits, consents, orders or authorizations of any governmental entity or regulatory authority in the DRC required to be obtained in connection with the Transaction.

(19) To the best of our knowledge, information and belief, there are no disputes or potential disputes with any third party in relation to the title or rights to the Exploitation Permits and Exploration Permits held by any of the Banro DRC Companies.

By way of additional information, we confirm that the claims made by Somico S.A.R.L. (in liquidation) and Mr. Moto Mabanga (together, the “Claimants”) two years ago against Banro Congo in respect of its real estate properties in the DRC (the “Suit”) have been definitely dismissed by the Supreme Court in the DRC on the grounds that such claims have no foundation in law and there is accordingly no prospect of any of these claims being resurrected by the aforementioned parties.

The Suit brought before the Supreme Court in the DRC related to the allegations brought by the claimants as to the actual ownership of three real estate properties held by Banro Congo located in Kinshasa. The Claimants were of the view that since the existence of the Presidential Decree No.103 of 29 July 1998 (the “Presidential Decree”) founding Somico S.A.R.L, as a State owned company, that ownership of the referred real estate properties passed onto them and that Somico S.A.R.L was still in existence. Somico S.A.R.L in its enthusiasm took possession of Banro Congo properties without title or right until 2002 when the Settlement Agreement was signed.

In its defense, Banro Congo argued that none of the provisions of the Presidential Decree transferred ownership of the real estate properties to Somico S.A.R.L. In addition, Presidential Decree No. 04/065 of 5 July 2004 cancelled the previous Presidential Decree and dissolved Somico S.A.R.L as a company; consequently that the Suit must be dismissed.

It is our further opinion that:

(1) Title: Pursuant to the Mining Convention, the State is obligated to renew title to the Exploitation Permits or to grant other forms of title with identical terms and conditions as those contained in Section 3 of the Mining Convention during term of the Mining Convention. In addition, Section 340 of the New Mining Code grants to the holders of new mining titles arising out of the Mining Convention the right to maintain the terms and conditions as stated in their respective original conventions. Section 273 also provides a guarantee by the State with respect to the rules and agreements or Conventions entered into with partners.

(2) Term: The initial term of the Mining Convention is 30 years ending March 13, 2027, subject to an extension under the New Mining Code which will be considered pursuant to the terms and conditions of the New Mining Code in existence at the time; at present, an extension can be granted until exhaustion of all reserves (whether delineated at prior to the grant of the Exploitation Permits or subsequently during mining operations or otherwise) pursuant to Article 67 of the New Mining Code.

(3) DRC Companies, etc: Notwithstanding that the Banro DRC Companies were not incorporated on the date of the Mining Convention, or the Amendment thereto, the Banro DRC Companies, as well as all third party beneficiaries referred to in Articles 8 through 34 of the Mining Convention (such as agents, suppliers, contractors, employees and money-lenders), have the rights purportedly ascribed therein and thereto, and the Mining Convention is otherwise fully enforceable in accordance with its terms. Third parties involved in projects pertaining to the Banro DRC Companies are also entitled to benefit from the abovementioned rights through the provisions of Section 18 of the Mining Convention.

(4) Development Obligations: The production, investment and employment targets set out in Sections 6.1, 6.2, 6.3, 6.4 and 6.5 of the Mining Convention are not binding upon Banro because the figures referred to in these sections are estimations and projections that may change depending on the local and international parameters relating to the stability of the country and the gold market.

(5) Taxes, etc: No laws relating to taxation, export or import of products, or royalties, which would otherwise be applicable to mining companies operating within the DRC, are or will be applicable to Banro insofar as the Exploitation Permits are concerned, as all such laws are displaced and superceded by the provisions of the Mining Convention.

(6) Development Permits, etc: In order to commence production on the Exploitation Permits, or any part thereof, Banro has applied for an environmental permit (through submission of an Assessment of Environmental Impact and Environmental Management Plan) which has been approved on 28 March 2006, and will be required to apply for a processing permit for which Banro could expect to receive the assistance of the State in this regard pursuant to Article 43 of the Mining Convention.

(7) Surface Rights: Banro has the full right to use all of the surface area contained within the Exploitation Permits and no other user of the surface, nor any occupier thereof, is entitled to any compensation or rights of relocation should Banro engage in construction activities that interfere with other uses of the surface. However, Banro is legally forbidden from conducting its mining activities in a surface zone that may be less than fifty meters around villages. Areas where artisan miners are present within the boundaries of the Exploitation Permits are operating illegally and will be removed upon proper request being made to the relevant authorities.

(8) Export Right: The right of export of products in Article 25 of the Mining Convention is absolute and supersedes Article 85 of the New Mining Code, which otherwise would require processing within the DRC of unprocessed products.

(9) New Mining Code: Banro is required to adhere to the terms and conditions of the New Mining Code, as it may be amended from time to time, with respect to the maintenance of its mining title (as contemplated in Article 45 of the Mining Convention), including those obligations to make reports under the New Mining Code (as contemplated in Article 39 of the Mining Convention) and to renew the Exploitation Permits when required; however, Banro is not required to otherwise adhere to the fiscal requirements of the New Mining Code, including those requirements to make annual and royalty payments, pay turnover tax, corporate tax, withholding tax, import tax, land surface fees or land tax, repatriate revenues for local costs, comply with the “import regime” of the Mining Code, or to commence work on its Exploitation Permits within three years of the date of issue of the title evidencing this right (as contemplated in Article 197 of the New Mining Code).

(10) Approval: The Amendment was approved by decree of the President of the Democratic Republic of the Congo, as required pursuant to Article 48 of the Mining Convention, on March 30, 2003.

(11) Expansion: Any mining expansion works undertaken by Banro during the term of the Mining Convention (that is to say, works undertaken relating to mineral substances granted by the Mining Registry other than these referred to in the original exploration permit delivered to Banro) will be subject to terms of the provisions of the referred Mining Convention, especially with regard to the customs and tax provisions therein. This is to say that Banro will benefit from all tax exemptions referred to in the Mining Convention. However, if the mining expansion works are undertaken beyond the term of the Mining Convention then provisions of the New Mining Code will govern such expansion works.

(12) Prior Environmental Damage: Pursuant to the New Mining Code, Banro has no liability with respect to the mining operations carried on before February 1997 within the boundaries of the Exploitation Permits, including tin and gold mining operations.

(13) Mining Contracts Review Process: The notification letter dated 18 February 2008 addressed by the Minister of Mines to Banro and the references to Sakima (ex-Sominki)/Banro contained therein as well as the conclusions of the report of the Commission de Revisitation des Contrats Miniers at the Ministry of Mines of the Democratic Republic of the Congo, dated November 2007, on page 24 thereof, should be regarded as working documents which do not have yet any legal effect and do not impact on the Mining Convention and Banro Exploitation Permits. As pointed in the response letter addressed to the Minister of Mines, Banro is not liable for any tax liability because it enjoys exoneration of taxes and duties in accordance with the terms of the Mining Convention. In addition, as previous shareholder in Sakima and/or Sominki, Banro does not have any obligations to meet winding up costs of the referred companies which are independents entity distinct from their shareholders under the DRC Corporate law.

(14) Correspondence with the government of the DRC: Since the Settlement Agreement and excepting the letter of notification of 18 February 2008 and Banro’s response thereto, Banro has had no correspondence with or from the government of the Democratic Republic of the Congo nor any agency thereof.

(15) We have reviewed the preliminary short form prospectus dated 02 September 2008 prepared in relation to the Transaction (the “Prospectus”) and are of the opinion that the sections in the Prospectus addressing matters of DRC law( including, without limitation, under “Business of the Company” and “Risk Factors” is true, complete and accurate as at the date hereof”)

We issue this opinion as attorneys admitted to the Bar of Kinshasa and our Opinion herein is restricted to the laws of the DRC as of the date hereof. We express no opinion as to the law of any other jurisdiction.

	Very truly yours,

	DJUNGA & RISASI

The undersigned, a securityholder of Banro Corporation (the “Corporation”), understands that RBC Dominion Securities Inc., CIBC World Markets Inc., UBS Securities Canada Inc. and Xxxxxxx Xxxxx Ltd.

The undersigned understands that the Corporation and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the Offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s legal representatives, successors, and assigns, and shall enure to the benefit of the Corporation, the Underwriters and their legal representatives, successors and assigns. This Lock-Up Agreement shall be governed by and construed in accordance with the laws of the Province of Ontario and the laws of Canada applicable therein and the parties hereto hereby agree to attorn to the non-exclusive jurisdictions of the court of the Province of Ontario in connection with any dispute or claim hereunder.
