If Initial Completion has not been achieved [PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY]* but the results of the last completed Completion Test *[PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY], then the Owners shall pay Silver Wheaton, by the delivery, within five (5) Business Days of the end of [PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY]* prior to Initial Completion being achieved (each an "Initial Monthly Delivery Period"), an amount of Refined Silver equal to the Refined Silver that would have otherwise been delivered to Silver Wheaton during each Initial Monthly Delivery Period if Initial Completion had been achieved. For purposes of determining the amount of Refined Silver that would have otherwise been delivered to Silver Wheaton during an Initial Monthly Delivery Period, the Refined Silver due to Silver Wheaton pursuant to Section 5(a) shall be multiplied by a fraction the numerator of which will be the Initial Targeted Capacity and the denominator of which will be the average daily throughput capacity achieved during the last completed Completion Test.

(d)	The Owners shall perform and complete a Completion Test as and when determined by them, *[PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY]. If Final Completion is achieved on or prior to [PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY], then the remainder of this Section 8(d) and Section 8(e) shall not apply. If Final Completion has not been achieved [PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY]* but the results of the last completed Completion Test *[PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY], then the Owners shall pay Silver Wheaton, by the delivery, within five (5) Business Days of the end of each of [PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY]* being achieved (each a "Final Monthly Delivery Period"), an amount of Refined Silver equal to the Refined Silver that would have otherwise been delivered to Silver Wheaton during each Final Monthly Delivery Period if Final Completion had been achieved. For purposes of determining the amount of Refined Silver that would have been delivered to Silver Wheaton during a Final Monthly Delivery Period, the Refined Silver due to Silver Wheaton pursuant to Section 5(a) shall be multiplied by a fraction the numerator of which will be the Final Targeted Capacity and the denominator of which will be the average daily throughput capacity achieved during the last completed Completion Test. For greater certainty and the avoidance of any doubt, if the Owners are required to sell and deliver Refined Silver to Silver Wheaton under this Section 8(d),

	then they shall not be required to sell and deliver Refined Silver to Silver Wheaton under Section 5(a) and the remainder of Section 5 shall continue to apply.

(e)	If the Owners do not perform and complete a Completion Test *[PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY], then the Mine will be deemed to have extracted, and the Mineral Processing Facility will be deemed to have processed, an average of 0 tons of ore per day [PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY]. If, at any time during the period between the date that is [PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY]* the date that is the Outside Completion Date, the Owners perform and complete a Completion Test with results that are *[PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY], then Section 20(a)(iii) shall apply, unless prior to Silver Wheaton exercising its rights under Section 20(b), the Owners perform and complete a subsequent Completion Test with results that are [PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY]*.

(f)	If Final Completion has not been achieved on or prior to the Outside Completion Date, the Owners shall refund (the "Capacity Related Refund") a portion of the Deposit to Silver Wheaton within thirty (30) days of the Outside Completion Date. The amount of the Capacity Related Refund shall equal the Deposit multiplied by the percentage equal to one hundred percent (100%) less the percentage that the actual throughput attained during the most recently completed Completion Test is of the Final Targeted Capacity. *[PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY]*. Notwithstanding any payment of the Capacity Related Refund by the Owners to Silver Wheaton, the Owners shall still be required to sell to Silver Wheaton twenty-five percent (25%) of the Payable Silver mined, produced, extracted or otherwise recovered from the Mining Properties in accordance with the terms of this Agreement.

(g)	If the Owners are required to pay Silver Wheaton a Capacity Related Refund in accordance with Section 8(f), then Final Completion shall be deemed to have been achieved.

9.	Processing/Commingling

20.	Events of Default and Remedies

	(i)	the Owners fail to sell and deliver Refined Silver to Silver Wheaton in accordance with Section 5 of this Agreement within five (5) Business Days of the date by which the Owners are required to sell and deliver Refined Silver;

	(ii)	the Owners do not perform and complete a Completion Test on or before the six (6) month anniversary of the Targeted Completion Date and/or, at any time during the period that is thirty (30) months from the Targeted Completion Date, the Owners perform and complete a Completion Test with results that are less than fifty percent (50%) of the Initial Targeted Capacity;

	(iii)	the Owners do not perform and complete a new Completion Test within six (6) months of the thirty (30) month anniversary of the Targeted Completion Date and/or if, at any time during the period between the date that is thirty (30) months from the Targeted Completion Date and the date that is the Outside Completion Date, the Owners perform and complete a Completion Test with results that are less than fifty percent (50%) of the Final Targeted Capacity;

	(iv)	if applicable, the Owners do not deliver the amount of Refined Silver required under Sections 8(b) or (d);

	(v)	the Owners fail to pay the Capacity Related Refund in accordance with Section 8(f);

	(vi)	the Water Licence has not been issued to and in the name of the an Owner by December 31, 2010;

	(vii)	the Owners are in breach or default of any of its representations, warranties, covenants or obligations set forth in this Agreement in any material respect, including the delivery of Monthly Reports and Annual Reports in accordance with the terms of this Agreement, and such breach or default is not remedied within the Cure Period;

	(viii)	Alexco is in breach or default of any of its representations or warranties set forth in this Agreement in any material respect and such breach or default is not remedied within the Cure Period;

	(ix)	Alexco is in breach or default of any of its covenants or obligations set forth in this Agreement in any material respect, other than its covenants and obligations set forth in Section 18 of this Agreement, and such breach or default is not remedied within the Cure Period;

	(x)	Alexco is in breach or default of any of its covenants or obligation set forth in Section 18 of this Agreement;

	(xi)	the Existing Alexco Entities are in breach or default (or an event which with notice or lapse of time or both would become a default) under any of the Silver Wheaton Security Agreements or any Permitted Initial Project Financing or the GSA;

	(xii)	the conditions set forth in Section 3(c) have not been satisfied in full on or before the date that is ninety (90) days from the Effective Date;

	(xiii)	the conditions set forth in Section 3(d) have not been satisfied by the Owners by December 31, 2009; and

	(xiv)	upon the occurrence of an Insolvency Event affecting either or both of the Owners or Alexco; provided that any action under any bankruptcy or insolvency law which is frivolous or vexatious, which is contested by the Party made subject to the Insolvency Event in good faith and which is discharged or dismissed within sixty (60) days from commencement, shall not constitute an Insolvency Event for the purpose of this section.

(b)

If an Event of Default occurs and is continuing, Silver Wheaton shall have the right, upon written notice to the Owners, at its option and in addition to and not in substitution for any other remedies available at law or equity, to demand repayment of the outstanding balance of the Deposit, if any, calculated under Section 3(f), at the time of the occurrence of such Event of Default, together with any and all damages or losses resulting or arising from the occurrence of an Event of Default (the “Default Fee”). The Default Fee shall accrue interest at a rate of [PROPRIETARY TERMS – REDACTED FOR CONFIDENTIALITY] per annum, compounded monthly, from the date of demand until the Default Fee is paid in full. Upon demand from Silver Wheaton, which demand shall include a calculation of the Default Fee, the Owners shall promptly pay the Default Fee to Silver Wheaton by wire transfer, in immediately available funds, to a bank account designated by Silver Wheaton. For greater certainty, in the event the Owners are required to pay the Default Fee under this Section 20(b), the provisions of Section 3 requiring the payment of a Deposit Refund will no longer be applicable and upon payment of the Default Fee to Silver Wheaton then the obligation of the Owners to sell Refined Silver to Silver Wheaton, as set out in Section 2(a), will no longer be applicable.

21.	General Provisions

(n)	This Agreement may not be changed, amended or modified in any manner, except pursuant to an instrument in writing signed on behalf of each of the Parties. The failure by any Party to enforce at any time any of the provisions of this Agreement shall in no way be construed to be a waiver of any such provision unless such waiver is acknowledged in writing, nor shall such failure affect the validity of this Agreement or any part thereof or the right of any Party to enforce each and every provision. No waiver or breach of this Agreement shall be held to be a waiver of any other or subsequent breach.

(r)	This Agreement constitutes the entire agreement between the Parties with respect to the subject matter hereof and cancels and supersedes any prior understandings and agreements between the Parties with respect thereto.

Dispute Resolution

The following rules and procedures shall apply with respect to any matter to be arbitrated by the Parties under the terms of the Agreement.

1.	Initiation of Arbitration Proceedings

(a)	If any Party to this Agreement wishes to have any matter under this Agreement arbitrated in accordance with the provisions of this Agreement, it shall give notice to the other Party hereto specifying particulars of the matter or matters in dispute and proposing the name of the person it wishes to be the single arbitrator. Within 20 days after receipt of such notice, the other Party to this Agreement shall give notice to the first Party advising whether such Party accepts the arbitrator proposed by the first Party. If such notice is not given within such 20 day period, the other Party shall be deemed to have accepted the arbitrator proposed by the first Party. If the Parties do not agree upon a single arbitrator within such 20 day period such arbitrator shall be chosen in accordance with the Arbitration Rules.

(b)	The individual selected as Arbitrator shall be qualified by education and experience to decide the matter in dispute. The Arbitrator shall be at arm’s length from both Parties and shall not be a member of the audit or legal firm or firms who advise either Party, nor shall the Arbitrator be a person who is otherwise regularly retained by either of the Parties.

2.	Submission of Written Statements

(a)	Within 20 days of the appointment of the Arbitrator, the Party initiating the arbitration (the “Claimant”) shall send the other Party (the “Respondent”) a statement of claim setting out in sufficient detail the facts and any contentions of law on which it relies, and the relief that it claims.

	(i)	Within 15 days of the receipt of the statement of claim, the Respondent shall send the Claimant a statement of defence stating in sufficient detail which of the facts and contentions of law in the statement of claim it admits or denies, on what grounds, and on what other facts and contentions of law he relies.

	(ii)	Within 10 days of receipt of the statement of defence, the Claimant may send the Respondent a statement of reply.

	(iii)	All statements of claim, defence and reply shall be accompanied by copies (or, if they are especially voluminous, lists) of all essential documents on which the Party concerned relies and which have not previously been submitted by any Party, and (where practicable) by any relevant samples.

	(iv)	After submission of all the statements, the Arbitrator will give directions for the further conduct of the arbitration.

3.	Meetings and Hearings

(a)	The arbitration shall take place in Vancouver, British Columbia or in such other place as the Claimant and the Respondent shall agree upon in writing. The arbitration shall be conducted in English unless otherwise agreed by such Parties and the Arbitrator. Subject to any adjournments which the Arbitrator allows, the final hearing will be continued on successive working days until it is concluded.

(b)	All meetings and hearings will be in private unless the Parties otherwise agree.

(c)	Any Party may be represented at any meetings or hearings by legal counsel.

(d)	Each Party may examine, cross-examine and re-examine all witnesses at the arbitration.

4.	The Decision

(a)	The Arbitrator will make a decision in writing and, unless the Parties otherwise agree, will set out reasons for decision in the decision.

(b)	The Arbitrator will send the decision to the Parties as soon as practicable after the conclusion of the final hearing, but in any event no later than 30 days thereafter, unless that time period is extended for a fixed period by the Arbitrator on written notice to each Party because of illness or other cause beyond the Arbitrator’s control.

(c)	The decision shall determine and award costs.

(d)	The decision shall be final and binding on the Parties and shall not be subject to any appeal or review procedure provided that the Arbitrator has followed the rules provided herein in good faith and has proceeded in accordance with the principles of natural justice. In the event either Party initiates any court proceeding in respect of the decision of the Arbitrator or the matter arbitrated, such Party, if unsuccessful in the court proceeding, shall pay the other Party’s costs on a solicitor/client basis, all reasonable expenses incurred by such other Party and related to such court proceeding.

5.	Jurisdiction and Powers of the Arbitrator

(a)	By submitting to arbitration under these Rules, the Parties shall be taken to have conferred on the Arbitrator the following jurisdiction and powers, to be exercised at the Arbitrator’s discretion subject only to these Rules and the relevant law with the object of ensuring the just, expeditious, economical and final determination of the dispute referred to arbitration.

(b)	Without limiting the jurisdiction of the Arbitrator at law, the Parties agree that the Arbitrator shall have jurisdiction to:

	(i)	determine any question of law arising in the arbitration;

	(ii)	determine any question as to the Arbitrator’s jurisdiction;

	(iii)	determine any question of good faith, dishonesty or fraud arising in the dispute;

	(iv)	order any Party to furnish further details of that Party’s case, in fact or in law;

	(v)	proceed in the arbitration notwithstanding the failure or refusal of any Party to comply with these Rules or with the Arbitrator’s orders or directions, or to attend any meeting or hearing, but only after giving that Party written notice that the Arbitrator intends to do so;

	(vi)	receive and take into account such written or oral evidence tendered by the Parties as the Arbitrator determines is relevant, whether or not strictly admissible in law;

	(vii)	make one or more interim awards;

	(viii)	hold meetings and hearings, and make a decision (including a final decision) in Vancouver, British Columbia or elsewhere with the concurrence of the Parties thereto;

	(ix)	order the Parties to produce to the Arbitrator, and to each other for inspection, and to supply copies of, any documents or other evidence or classes of documents in their possession or power which the Arbitrator determines to be relevant; and

	(x)	make interim orders to secure all or part of any amount in dispute in the arbitration.
