	(e)	At the Purchaser’s request, Banro shall, and shall cause the Seller (and any other Banro Group Entity from which Produced Gold is sold) to provide in any Processing Agreement or selling agreement that the account with any third party in respect of any Refined Gold related to the Produced Gold will form part of the Project Collateral.

7.3

Processing/Commingling

Banro and the Seller shall not and shall cause each of the Banro Group Entities to not process Other Minerals through the Processing Plant in priority to, or commingle Other Minerals with, gold mined, produced, extracted or otherwise recovered from the Properties, unless (i) the applicable Banro Group Entity has adopted and employs reasonable practices and procedures for weighing, determining moisture content, sampling and assaying and determining recovery factors (a “Commingling Plan”), such Commingling Plan to ensure the division of Other Minerals and Produced Gold for the purpose of determining the quantum of Produced Gold; (ii) the Purchasers shall not be disadvantaged as a result of the processing of Other Minerals in priority to, or concurrently with, Produced Gold; (iii) the Agent has approved the Commingling Plan, such approval not to be unreasonably withheld; (iv) the Banro Group Entity keeps all books, records, data, information and samples required by the Commingling Plan; and (v) the Banro Group Entity enters into a commingling agreement with the Agent, for and on behalf of the Purchasers, that provides that there is no negative impact on the gold production attributable to the stream as a result of the commingling. The Seller agrees to revisit the Commingling Plan if the Agent determines that circumstances have changed, in order to ensure that the Commingling Plan continues to provide for the accurate measurement of gold produced from the Properties.

7.4

Processing Agreements

	(a)	From and after the date hereof, the Seller (together with the PSA Entities from which Produced Gold is sold) shall be a party to any Processing Agreements and the PSA Entities party thereto shall be responsible for delivering all gold to each Processor, in such quantity, description and amounts and at such times and places as required under and in accordance with each Processing Agreement.

- 32 -

(d)

Banro shall ensure that the final sale and delivery of doré shall only be made to a Processor pursuant to a Processing Agreement. For greater certainty, nothing in this Section 7.4(d) shall prohibit the processing of Produced Gold by a PSA Entity, provided that the doré is eventually sold to a Processor.

7.5

Insurance

	(a)	Banro and the Seller shall maintain with reputable insurance companies insurance with respect to the Project Assets and the operations conducted on and in respect of the Namoya Project against such casualties and contingencies and of such types and in such amounts as is customary in the case of similar operations and, until the Deposit Reduction Date, shall have the Agent, on behalf of the Purchasers added as an additional insured and loss payee in the insurance policies.

	(b)	The Seller shall ensure that each shipment of gold is adequately insured in such amounts and with such coverage as is customary in the mining industry, until the time that risk of loss and damage for such gold is transferred to the processor.

	(c)	When a Banro Group Entity receives payment under any insurance policy in respect of a shipment of Produced Gold that is lost or damaged after leaving the Namoya Project and before the risk of loss or damage is transferred to the Processor, the Seller shall use 10% of the amount of the Net Proceeds of any insurance payment received by the Banro Group Entity in respect thereof to acquire Refined Gold in accordance with Section 2.2(d) and shall sell and deliver to the Purchasers, in accordance with each Purchaser’s Applicable Percentage, (without duplication to the extent previously sold and delivered to the Purchasers by the Seller) such amount of Refined Gold at the applicable Gold Purchase Price.

	(d)	Banro and the Seller shall insure the Project in such amounts and with such coverage as is customary in the mining industry for the construction, development and operation of the Project, including the Processing Plant. Banro and the Seller covenant and agree that in the event of any loss or damage that is insured prior to the date on which the uncredited balance of the Deposit has been reduced to nil, the Seller shall either (i) use all Net Proceeds of any insurance payment received by the Banro Group Entity to rebuild or repair all damaged facilities forming part of the Namoya Project, or (ii) use each Purchaser’s share of the Net Proceeds of such insurance payment received by any Banro Group Entity within 30 days after receipt of such proceeds by such Banro Group Entity, to acquire Refined Gold in accordance with Section 2.2(d) and shall deliver to the Purchasers, in accordance with each Purchaser’s Applicable Percentage, such amount of Refined Gold, each Purchaser’s share being calculated as the ratio of the fair value of each Purchaser’s interest in the Namoya Project (taking into account each Purchaser’s Applicable Percentage) as represented by its rights under this Agreement to the value of Banro’s interests in the Namoya Project when measured by the same criterion which establishes the value of such Purchaser’s interest. A failure to agree on the foregoing proportion is arbitrable under Section 14.1.

- 33 -

	(e)	Banro and the Seller shall, on or prior to the Closing Date and upon the reasonable request of the Agent at reasonable intervals no more than once per year, furnish to the Agent a certificate setting forth the nature and extent of all insurance maintained by or on behalf of the PSA Entities in accordance with Section 7.5(a). Banro and the Seller shall, upon the request of the Agent, provide the Purchasers with copies of all insurance policies as in effect from time to time relating to the Project Assets.

	(f)	Banro and the Seller, acting reasonably, shall not at any time do or omit to do anything, or cause anything to be done or omitted to be done, whereby any insurance required to be effected hereunder would, or would be likely to, be rendered void or voidable or suspended, impaired or defeated in whole or in part.

	(i)	to its auditor, legal counsel, lenders, brokers, underwriters and investment bankers and to persons with which it is considering or intends to enter into a transaction for which such Confidential Information would be relevant (and to the legal counsel and advisors of any such entity), provided that such persons are advised of the confidential nature of the Confidential Information, undertake to maintain the confidentiality of it and are strictly limited in their use of the Confidential Information to those purposes necessary for such persons to perform the services for which they were, or are proposed to be, retained by the Receiving Party or to consider or effect the applicable transaction, as applicable;

	(ii)	subject to Sections 7.6(c) and 14.9, where that disclosure is necessary to comply with Applicable Laws or court order, provided that such disclosure is limited to only that Confidential Information so required to be disclosed and that the Receiving Party will have availed itself of the full benefits of any laws, rules, regulations or contractual rights as to disclosure on a confidential basis to which it may be entitled;

	(iii)	for the purposes of the preparation of any arbitration proceeding commenced under Section 14.1;

- 34 -

	(iv)	where such information is already widely known by the public other than by a breach of the confidentiality terms of this Agreement or is known by the Receiving Party prior to the entry into of this Agreement or obtained independently of this Agreement and the disclosure of such information would not breach any other confidentiality obligations;

	(v)	with the consent of the disclosing Party; and

	(vi)	to those of its and its Affiliates’ directors, officers, employees, representatives and agents who need to have knowledge of the Confidential Information for purposes of the rights and obligations contemplated by this Agreement.

	(b)	Each Party shall ensure that its and its Affiliates’ employees, directors, officers, representatives and agents and those persons listed in Section 7.6(a)(i) are made aware of this Section 7.6 and comply with the provisions of this Section 7.6. Each Party shall be liable to the other Party for any improper use or disclosure of such terms or information by such persons.

	(c)	If in compliance with Applicable Laws, either Party is required to file this Agreement on SEDAR or XXXXX, such Party shall notify the other Party of such requirement within two Business Days of the date of this Agreement, and the Parties shall consult with each other with respect to any proposed redactions to the Agreement in compliance with Applicable Laws before it is filed on SEDAR or XXXXX. Neither Party shall file this Agreement on SEDAR or XXXXX without reasonable prior consultation with the other Party, provided that such reasonable prior consultation shall not prohibit either Party from filing this Agreement on SEDAR or XXXXX redacted only to the extent such Party considers it permitted pursuant to Applicable Laws.

	(d)	The PSA Entities and the Agent will consult with each other before issuing any press release or otherwise making any public disclosure in respect of this Agreement and the transactions contemplated hereunder and shall not issue any such press release or make any such public disclosure before receiving the consent of the other Party. Nothing in this Section 7.6(d) prohibits any party from making a press release or other disclosure required by Applicable Laws or by the policies or rules of any stock exchange.

The Parties acknowledge and agree that any breach by Banro of its obligations under this Section would cause the Agent and the Purchasers irreparable harm for which monetary damages alone would not be a sufficient remedy and that therefore the Agent and the Purchasers may seek and obtain orders of specific performance, injunctions and other equitable remedies and remedies available under civil laws against Banro with respect thereto as a court of competent jurisdiction or an arbitrator under Section 14.1 may see fit to grant with respect to any such breach and neither Banro, the Seller or any Banro Group Entity shall oppose or seek to deny any such remedies.

For certainty, and at all times, the Seller shall not, and Banro shall ensure that the Seller does not, make any Distributions other than a Permitted Distribution from such account if a Banro Event of Default, or event which with the giving of notice or the passage of time or both would constitute a Banro Event of Default, has occurred and is continuing, or if a Banro Event of Default would occur or arise immediately after, or as a result of, making a Distribution.

	(f)	The PSA Entities shall cause all such further agreements, instruments and documents to be executed and delivered and all such further acts and things to be done as the Agent may from time to time reasonably require to obtain, perfect and maintain first ranking prior perfected charges and security interests in, to and over all of the PSA Collateral, subject only to Prior Ranking Permitted Encumbrances.

	(g)	Banro and the Seller shall not, and shall cause each Banro Group Entity to not, contest in any manner the effectiveness, validity, binding nature or enforceability of this Agreement or any of the PSA Security.

	(h)	In addition to the foregoing, Banro, the Seller and each applicable Banro Group Entity that has provided security to one or more Lenders where such security also secures the PSA Obligations shall not seek any discharge of any such security except where the Agent has provided its prior written consent, in its sole discretion, with a view to ensuring that such security or any replacement security in favour of the Agent continues to secure the PSA Obligations and with no change in the priority thereof. The Seller shall pay all costs and expenses associated with the foregoing including in connection with the preparation and registration of all documentation in connection therewith that is required by the Agent.

Intercreditor Agreement

If, after the Deposit Reduction Date, any PSA Entity wishes to enter into any Secured Financing or grant an Encumbrance over any PSA Collateral to any Lenders as security for the payment or performance of any Secured Financing, and it is the intention of such PSA Entity that such Encumbrance modify the security interests in favour of the Agent set out in Section 9.2, then the Agent, for and on behalf of the Purchasers, agrees to enter into an intercreditor agreement (in each such case, an “Intercreditor Agreement”) with the Lenders and the applicable PSA Entity (such agreement to be negotiated in good faith), on the principal terms and conditions set out in Schedule C. The Parties agree that if an Intercreditor Agreement is not negotiated and executed within 60 days of the Purchasers receiving notice from a PSA Entity that it intends to enter into a Secured Financing or grant on Encumbrance, then either Party may seek to have any dispute related thereto determined by arbitration as set out in Section 14.1.

9.4

Stockpiling

The Seller shall not stockpile, store or place Produced Gold off of the Properties unless the Seller has first secured from the property owner where such stockpiling, storage or placement is to occur a written agreement in recordable form which provides that the Purchasers’ rights to the Produced Gold shall be preserved. Such agreement shall provide, inter alia, that (a) the Purchasers’ rights pursuant to this Agreement, insofar as they are applicable, shall continue in full force and effect; (b) the Purchasers’ rights in and to the Produced Gold shall be the same as if the Produced Gold were situate on the Properties; (c) the Purchasers’ rights set forth in this Section 9.4 shall have precedence over the rights to the Produced Gold of the property owner where the Produced Gold is stockpiled, stored or placed; (d) the agreement shall be irrevocable as long as the Produced Gold, or any part thereof, remains on the property not part of the Properties and (e) the Agent and the Purchasers shall have substantially similar access rights and obligations as provided in Section 6.6.

BANRO EVENTS OF DEFAULT

11.1

Banro Events of Default

Each of the following events or circumstances constitutes an event of default by the PSA Entities (each, a ”Banro Event of Default”):

	(a)	the Seller fails to sell and deliver the Payable Gold to the Purchasers on the terms and conditions set forth in this Agreement within three (3) Business Days after receipt of notice from the Agent notifying the Seller of such default;

	(b)	other than as provided in Section 11.1(a), any PSA Entity is in breach or default of any terms or conditions, or any of its covenants or obligations, set forth in this Agreement or any Security Agreement in any material respect, which breach or default is not remedied within a period of 30 days following delivery by the Agent to the PSA Entities of written notice of such breach or default, except in respect of the covenant set out in Section 7.10, which shall constitute a Banro Event of Default immediately on notice thereof, or such longer period of time as the Agent may determine in its sole discretion;

	(c)	any of the representations or warranties given by Banro and the Seller is inaccurate in any material respect as of the date given, and such inaccuracy is not remedied within a period of 30 days following delivery by the Agent to Banro and the Seller of written notice of such inaccuracy, or such longer period of time as the Agent may determine in its sole discretion;

- 44 -

	(d)	in respect of Indebtedness, any (i) failure by any Banro Group Entity to pay such Indebtedness at the stated maturity thereof or as a result of which, the holder of such Indebtedness has declared the principal thereof to be due and payable prior to the stated maturity thereof, or any event shall occur and shall continue after the applicable grace period (if any) specified in any agreement or instrument relating to any such Indebtedness of any Banro Group Entity, the effect of which is to permit the holder of such Indebtedness to declare the principal amount thereof to be due and payable prior to its stated maturity and in respect of which such holder has so declared the principal amount to be payable; or (ii) failure by any Banro Group Entity to perform or observe any covenant or agreement to be performed or observed by it contained in any other agreement or in any instrument evidencing any of such Indebtedness, the effect of which is to permit the holder of such Indebtedness to declare the principal amount thereof to be due and payable prior to its stated maturity and in respect of which the holder has so declared the principal amount to be payable or has sought to enforce a guarantee in respect thereof;

	(e)	upon the occurrence of an Insolvency Event affecting either Banro or the Seller; or

	(f)	except as otherwise contemplated herein, the PSA Security does not constitute a first ranking Encumbrance over the PSA Collateral, subject only to the Prior Ranking Permitted Encumbrances, and does not become a first ranking charge within 20 days of receipt of notice from the Agent notifying the PSA Entities of such default.

11.2

Remedies

(a)

If a Banro Event of Default occurs and is continuing, the Agent shall have the right, upon written notice to Banro and the Seller at its option and in addition to and not in substitution for any other remedies available at law or equity, to take any or all of the following actions:

	(i)	demand all amounts and deliveries owing by the Seller to the Purchasers;

	(ii)	terminate this Agreement by written notice to Banro and the Seller and, without limiting Section 11.2(a)(i), demand all losses suffered or incurred as a result of the occurrence of such Banro Event of Default and termination, including the greater of (A) the uncredited amount of the Deposit, and (B) a net present value calculation of the Payable Gold that would have been delivered by the Seller to the Purchasers hereunder, but for the occurrence of such Banro Event of Default. The net present value calculation shall be based on an assumption that the Project Assets are owned and operated by a person that has the financial, operational and technical capability of a prudent owner and operator, and shall be based on such other reasonable assumptions and forecasts as may be necessary to make such calculation, including with respect to the applicable discount rates to use, the applicable gold prices to use, and the reasonably expected Payable Gold that would have been sold and delivered to the Purchasers hereunder but for the occurrence of such Banro Event of Default (based on, among other factors, the reserves and resources, inferred resources and potential exploration success, the expected throughput through the Processing Plant, and expected gold recoveries). Upon demand from the Agent, the Seller shall promptly pay all such amounts to the Purchasers; and

- 45 -

(iii)

enforce the PSA Security.

	(b)	The Parties hereby acknowledge and agree that: (i) the Agent and the Purchasers will be damaged by a Banro Event of Default; (ii) it would be impracticable or extremely difficult to fix the actual damages resulting from a Banro Event of Default; (iii) any sums payable in accordance with Section 11.2(a) with respect to a Banro Event of Default are in the nature of liquidated damages, not a penalty, and are fair and reasonable; and (iv) the amount payable in accordance with Section 11.2(a) or with respect to a Banro Event of Default represents a reasonable estimate of fair compensation for the losses that may reasonably be anticipated from such Banro Event of Default in full and final satisfaction of all amounts owed in respect of such Banro Event of Default.

	(c)	For greater certainty, if the Agent, for and on behalf of the Purchasers does not exercise its right under Section 11.2(a)(ii), the obligations of Banro and the Seller or any successors shall continue in full force and effect.

ARTICLE 12
PURCHASER EVENTS OF DEFAULT

12.1

Purchaser Events of Default

Each of the following events or circumstances constitutes an event of default by the Purchaser (each, a “Purchaser Event of Default”):

	(a)	a Purchaser fails to pay a portion of the Deposit in accordance with Article 3 within (3) three Business Days of receipt of notice from the Seller notifying such Purchaser of such default (a “Deposit Default”);

	(b)	a Purchaser fails to pay for Payable Gold delivered to the Purchaser in accordance with Section 2.4 within (3) three Business Days of receipt of notice from the Seller notifying such Purchaser of such default (a “Purchaser Payment Default”);

	(c)	a Purchaser is in breach or default of any of its covenants or obligations set forth in this Agreement in any material respect (other than a breach or default of the covenants or obligations referenced in Sections 12.1(a) or (b) above), and such breach or default is not remedied within a period of 30 days following delivery by the Seller to such Purchaser of written notice of such breach or default, or such longer period of time as the Seller may determine in its sole discretion; or

- 46 -

(d)

any of the representations or warranties given by a Purchaser is inaccurate in any material respect as of the date given, and such inaccuracy is not remedied within a period of 30 days following delivery by the Seller to such Purchaser of written notice of such inaccuracy, or such longer period of time as the Seller may determine in its sole discretion.

12.2

Remedies

	(a)	If there should occur a Deposit Default, the non- defaulting Purchasers may deliver the Deposit amount that is the subject of the Deposit Default, and to the extent they choose to do so, such funding Purchasers’ Applicable Percentage will be adjusted accordingly. If all of the conditions precedents set out in Section 3.3 have been satisfied and a Deposit Default in respect of all of the Deposit occurs and is continuing and the Purchasers fail to cure the Deposit Default in full within 90 days of written notice from the Seller of such default, then the Seller may elect to at any time thereafter so long as the Purchasers have not already cured the Deposit Default, to terminate the Agreement.

	(b)	In addition to the PSA Entities’ rights and remedies available at law or in equity (other than any right at law or in equity to terminate this Agreement), if a Purchaser Payment Default occurs and is continuing, the Seller shall have the right, upon written notice to the defaulting Purchaser, at its option, to suspend obligations under Section 2.2 solely in respect of the defaulting Purchaser. If the Deposit is reduced to nil and following the Deposit Reduction Date, the defaulting Purchaser fails to cure the Purchaser Payment Default in full within 30 days, then the Seller may elect at any time thereafter so long as such defaulting Purchaser has not already cured the Purchaser Payment Default, to terminate the Agreement solely with respect to such defaulting Purchaser and thereupon all of the Seller’s obligations hereunder with respect to such defaulting Purchaser shall thereafter be terminated without prejudice to any other right or remedy it may have against such defaulting Purchaser. For greater certainty, the PSA Obligations shall continue unaffected in respect of the non-defaulting Purchasers.

	(c)	If a Purchaser Event of Default under Sections12.1(c) or 12.1(d) has occurred and is continuing, then the PSA Entities shall have no right to terminate this Agreement, but shall be entitled to all other remedies available to it at law or in equity against the Purchaser.
