For this purpose, Payable Gold means the recoverable metal content calculated in accordance with the applicable Non-Doré Agreement. The Seller shall be deemed to receive a Gold Payment when it receives payment (whether provisional or final) for a Non-Doré Shipment and the sale and delivery of the Payable Gold payable on account of the Non-Doré Shipments shall be made in accordance with Section 2.2.

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 Purchaser shall not be disadvantaged as a result of the processing of Other Minerals in priority to, or concurrently with, Produced Gold; (iii) the Purchaser 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 Purchaser 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 Purchaser 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.

- 35 -

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 Twangiza 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 Purchaser 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 Twangiza Project and before the risk of loss or damage is transferred to the Processor, the Seller shall use the Applicable Entitlement Percentage (determined as at the time the loss occurred) 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(e) and shall sell and deliver to the Purchaser (without duplication to the extent previously sold and delivered to the Purchaser by the Seller) such amount of Refined Gold at the applicable Gold Purchase Price.
	(d)	Banro and the Seller shall insure the Twangiza Project in such amounts and with such coverage as is customary in the mining industry for the construction, development and operation of the Twangiza 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 Twangiza Project, or (ii) use the 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(e) and shall deliver to the Purchaser such amount of Refined Gold, the Purchaser’s share being calculated as the ratio of the fair value of the Purchaser’s interest in the Twangiza Project as represented by its rights under this Agreement to the value of Banro’s interests in the Twangiza Project when measured by the same criterion which establishes the value of the Purchaser’s interest. A failure to agree on the foregoing proportion is arbitrable under Section 13.1.
	(e)	Banro and the Seller shall, on or prior to the Closing Date and upon the reasonable request of the Purchaser at reasonable intervals no more than once per year, furnish to the Purchaser 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).

	(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 13.9, 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 13.1;
	(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;

- 37 -

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 Purchaser 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.

7.7 Adverse Impact to Payable Gold

Banro and the Seller shall promptly notify the Purchaser regarding any matter that has or is reasonably likely to have a Material Adverse Effect or any occurrence of or circumstances that may result in a Banro Event of Default, including, for greater certainty, receipt of a notice of acceleration in respect of any indebtedness or obligations or an intention to enforce security against any of the Project Assets.

Banro shall guarantee that the Seller and all Banro Group Entities shall observe, satisfy, perform and pay all of their actions, covenants, indebtedness, liabilities and obligations in accordance with the terms of this Agreement. The Parties acknowledge and agree that any breach by Banro of its obligations under this Section would cause the Purchaser irreparable harm for which monetary damages alone would not be a sufficient remedy and that therefore the Purchaser 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 13.1 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.

	(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 Purchaser 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 Purchaser may determine in its sole discretion;

- 47 -

	(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 Purchaser notifying the PSA Entities of such default.

11.2 Remedies

(a) If a Banro Event of Default occurs and is continuing, the Purchaser 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:

	(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 Purchaser 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 Purchaser 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). In the event the Seller and the Purchaser do not agree on the reasonable assumptions and forecasts necessary to make such net present value calculation, the parties shall agree on the appointment of any one of the major audit firms, being PricewaterhouseCoopers Canada, Deloitte LLP, Ernst & Young or KPMG, to determine and calculate the net present value. Upon demand from the Purchaser, the Seller shall promptly pay all such amounts to the Purchaser; and

	(c)	For greater certainty, if the Purchaser 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.
