Page 4

ARTICLE III
Consideration

3.1. Consideration during the Lease Term. In addition to payment of the Claimholders’ Consideration, YCKM agrees and covenants that:

(a) On the Lease Closing Date YCKM shall (i) pay to ANF the Cash Payment set forth as the amount due to ANF on such date in Schedule B hereof and (ii) issue to the ANF Distributees in accordance with Section 3.3 hereof the number of Shares set forth as shares due to ANF on such date in Schedule B hereof.

(b) On each Lease Payment Date, YCKM shall (i) pay to the ANF Distributees in accordance with Section 3.3 hereof the amount of the Cash Payment set forth as the amount due to ANF on such date in Schedule B hereof and (ii) issue to the ANF Distributees in accordance with Section 3.3 hereof the number of Shares set forth as shares due to ANF on such date in Schedule B hereof.

(c) On each Supplemental Payment Date, YCKM shall pay to the ANF Distributees in accordance with Section 3.3 hereof the amount of the Supplemental Payment calculated in accordance with Schedule E hereof.

3.2. Consideration upon Exercise of Option. In the event YCKM exercises the Option in accordance with the Lease and Option Agreements, YCKM shall (i) pay to the ANF Distributees in accordance with Section 3.3 hereof during the Option Exercise Period the amount of the Cash Payment set forth as the amount due to ANF in Schedule C hereof with respect to the year of the Option Exercise Period during which the Option is exercised and (ii) issue to the ANF Distributees in accordance with Section 3.3 hereof the number of Shares set forth as shares due to ANF in Schedule C hereof with respect to the year of the Option Exercise Period during which the Option is exercised.

3.3. Distribution of ANF Payments and Shares.

(a) With the exception of the amount of the Cash Payment due to ANF on the Lease Closing Date, which shall be payable directly to ANF, YCKM shall pay the amount of the Cash Payments, and shall issue the Shares, due to ANF, to the members and designees of ANF set forth on Schedule D (“ANF Distributees”) in accordance with each ANF Distributee’s respective percentage interest in ANF (as set out in Schedule D) for the benefit of ANF, provided, however, that ANF shall indemnify and hold YCKM harmless from any claim, cause of action, damages, and costs arising out of or relating to the making of any Cash Payments or issuance of the Shares to the ANF Distributees, and ANF shall cause each ANF Distributee, at the option of YCKM, to execute such receipts and disclosure documents as YCKM or its counsel reasonably deem necessary or required as a condition to receiving a Cash Payment or Shares. YCKM’s making of Cash Payments and issuance of the Shares to the ANF Distributees shall constitute prima facie evidence of payment of the Cash Payments and issuance of the Shares due to ANF as required by this Article III.

(b) Nothing in Schedule D shall expand or modify YCKM’s obligations to ANF hereunder. YCKM shall have no obligation to make a Cash Payment and shall have no obligation to issue Shares to any party not designated as an ANF Distributee on Schedule D; provided, however, that in the event of any transfer of rights to receive Cash Payments or Shares that meets the

Page 5

requirements of Article X, YCKM shall have no obligation to recognize the transferee of an ANF Distributee’s rights until YCKM has received certified copies of all legal documents effectuating such transfer reasonably acceptable to YCKM, the transferee ratifies in writing the terms of this Agreement and executes such receipts and disclosure documents as YCKM its legal counsel reasonably deem necessary or required as a condition to receiving a Cash Payment or Shares and regulatory approval is obtained for the issuance of Shares to such transferee where such regulatory approval is required.

(c) Nothing in this Agreement shall, nor shall it be construed to, create or grant any enforceable right, claim or remedy in the ANF Distributees, and all such rights, claims and remedies are expressly reserved to ANF. To the extent the ANF Distributees are deemed to be third party beneficiaries under this Agreement, ANF shall indemnify and hold YCKM harmless from all claims, costs and liabilities arising out of a claim by an ANF Distributee.

3.4. Shares.

(a) The Shares shall be subject to resale restrictions which are required to be imposed on the Shares issued to the ANF Distributees hereunder, pursuant to applicable securities laws, including the rules and policies of any stock exchange upon which YCKM may be listed at the time and any applicable resale restrictions imposed by the U.S. Securities and Exchange Commission or under state securities laws.

(b) Each ANF Distributee entitled to Shares under this Agreement shall execute and deliver to YCKM a “Shareholder Questionnaire” in the form attached hereto as Schedule G in connection with the issuance of such Shares and agrees to YCKM filing certain personal information about the ANF Distributees with any stock exchange upon which YCKM may be listed at the time and applicable securities regulators as required by applicable securities laws and policies and the rules and policies of any such exchange. YCKM shall be entitled to reserve from issuance any Shares issuable to any ANF Distributee under this Agreement pending delivery of an executed Shareholder Questionnaire by such ANF Distributee.

3.5. Royalty.

(a) ANF acknowledges and represents that each of the Claimholders has entered into a royalty deed in favor of ANF (the “Royalty Deeds”), and that each of the Royalty Deeds is in the form attached as Schedule H hereto.

(b) YCKM hereby acknowledges and expressly assumes the burden of a royalty (the “Royalty”) granted pursuant to and on the terms and conditions of each Royalty Deed. The Royalty with respect to each of the Mining Properties shall become payable in accordance with the terms of the applicable Royalty Deed. YCKM shall pay the amount of the Royalty owing from time to time to ANF to the ANF Distributees, in accordance with each ANF Distributee’s respective percentage interest in ANF, as set out in Schedule D. ANF reserves the right to transfer, and nothing herein shall be construed in any manner to restrict the right of ANF to transfer, all or any portion of its interest in the Royalty to any one or more affiliated parties or third persons.

3.6. Option to Terminate or Exclude Defective Claims prior to the First Lease Payment Date. During the period between the Effective Date and the First Lease Payment Date (March 31, 2008), YCKM shall use reasonable diligence to investigate whether there exists any defect

Page 6

or competing rights of any third party to any of the mining claims included among the Mining Properties. YCKM’s investigation shall include an examination of public records relating to the Mining Properties as of not less than 90 days following the relevant filing dates of the Mining Properties as well as an on-site examination of each of the claims included within the Mining Properties. ANF shall provide reasonable cooperation and assistance to YCKM in its investigation, as reasonably requested by YCKM, including assistance locating the Mining Properties in the course of YCKM’s on-site examination. If as of the First Lease Payment Date, YCKM’s investigation has revealed that one or more of the mining claims included within the Mining Properties is subject to an incurable or potentially incurable defect in title or to valid or potentially valid competing rights of a third party (each, a “Defective Claim”), then YCKM has the following options under each of the Lease and Option Agreements:

i. YCKM may elect, by delivery of written notice to the relevant Lessor and ANF on or prior to the First Lease Payment Date, to exclude from the relevant Lease and Option Agreement any Defective Claim, provided that YCKM may not elect to exclude more than 80% of the mining claims included under any one Lease and Option Agreement;

ii. YCKM may elect, by delivery of written notice to the Lessor and ANF on or prior to the First Lease Payment Date, to terminate the relevant Lease and Option Agreement.

If YCKM elects to exclude any Defective Claims from one or more Lease and Option Agreements as described in this Section 3.6 or to terminate any Lease and Option Agreement(s) as described in this Section 3.6, then (i) Defective Claims excluded from any Lease and Option Agreement shall henceforth be deemed excluded in their entirety from this Agreement, (ii) all Mining Properties covered by terminated Lease and Option Agreements shall henceforth be deemed excluded in their entirety from this Agreement, (iii) all payments and issues of Shares to ANF pursuant to Sections 3.1(a), 3.1(b) and 3.2 shall be reduced by the percentage that the sum of the number of Defective Claims excluded from all the Lease and Option Agreements and the number of Mining Properties covered by terminated Lease and Option Agreements bears to the total number of mining claims included within the Mining Properties (the reduction in the amounts due and numbers of Shares issuable with respect to the First Lease Payment Date being applied against the amounts due and numbers of Shares issuable with respect to the Second Lease Payment Date, and, if necessary, subsequent Lease Payment Dates), (iv) YCKM shall make no claim against Lessor or ANF in the event that YCKM suffers any loss arising from the exclusion of such Defective Claims from this Agreement and the Lease and Option Agreements, and (v) notwithstanding anything to the contrary herein, neither ANF nor YCKM shall have any further liability to the other in respect of such Defective Claims and terminated Lease and Option Agreements. In the event that YCKM elects to terminate all of the Lease and Option Agreements as described in this Section 3.6, ANF shall promptly (i) repay to YCKM the amount paid to ANF on the Effective Date and (ii) reassign to YCKM the number of Shares issued to ANF on the Effective Date. Thereafter, this Agreement shall be terminated and notwithstanding anything to the contrary herein, neither ANF nor YCKM shall have any further liability to the other whatsoever. In no event shall ANF have any obligation to repay any amount paid or advanced to ANF and/or the Claimholders by YCKM prior to the Effective Date, and ANF shall be entitled to retain all such amounts distributed to ANF notwithstanding termination of this Agreement or one or more of the Lease and Option Agreements. If YCKM makes no election as described in this Section 3.6 either to

Page 7

exclude Defective Claims from any Lease and Option Agreement or to terminate any Lease and Option Agreement, then this Agreement shall remain in full force and effect and YCKM (i) shall be deemed to have accepted and consented to any defect in Lessor’s title to any Defective Claims that remain subject to the Lease and Option Agreements known to YCKM on or prior to the First Lease Payment Date, (ii) shall, upon exercise of the Option, take title to any such Defective Claims subject to any such defects, and (iii) shall make no claim against any Claimholder or ANF in the event that YCKM suffers any loss arising from such defects.

ARTICLE IV
Protection of Mining Properties

4.1. Property Maintenance.

(a) YCKM shall (i) pay all taxes levied or assessed against the Mining Properties and due during the Lease Term, and (ii) pay and perform all applicable fees and work requirements to hold the unpatented mining claims included in the Mining Properties and file and/or record in the applicable office(s) all evidence of such payments as is required by Law (the cost of which is referred to herein as “Property Maintenance Costs”) not less than forty-five (45) days prior to the date such obligations become due. YCKM shall provide ANF evidence of payment and performance of the Property Maintenance Costs as incurred and paid. Property Maintenance Costs shall constitute Qualified Expenditures.

All such locations, amendments, or relocations shall be made in the name of the relevant Claimholders. All expenses authorized by YCKM in connection with the locating, amending, or relocating mining claims or mill sites shall be borne by YCKM and shall constitute Qualified Expenditures for purposes of YCKM’s Work Commitment. The rights of YCKM under this Agreement shall extend to all such locations, amended locations, and relocations of the mining claims and mill sites, and the Royalty shall extend to all such locations. At the request of ANF or the relevant Claimholders, YCKM shall execute and record any documents necessary to clarify and confirm the interests of the Claimholders and ANF in the new, amended or relocated mining or mill site claims.

4.3. Change in Federal Mining Law. If the United States establishes a leasing system or other system of tenure for lands or minerals now subject to location under the mining laws, and if the new system gives the Claimholders an election to acquire rights under the new system in exchange for or in modification of the Claimholders’ existing rights, upon prior written consent of the Claimholders pursuant to the Lease and Option Agreements, YCKM may make the election in the name of the relevant Claimholders with respect to any or all of the unpatented claims included in the

Page 8

Upon termination of this Agreement by exercise of the Option, YCKM shall not be required to complete any Qualified Expenditures, the obligation for which has not yet matured; except that, for so long as the Mining Properties remain unpatented mining claims, and unless YCKM has abandoned such Mining Properties in compliance with Section 8.3 hereof, YCKM covenants and agrees, following such termination, to pay and perform, in a timely manner, all work upon the Mining Properties as is necessary to maintain the Mining Properties under all applicable Laws.

(a) If either party (the “Notifying Party”) believes the other party (the “Notified Party”) is in breach of this Agreement, the Notifying Party shall notify the Notified Party and give it the opportunity, as set forth in this subsection, to cure such breach. If the Notified Party does not:

i. cure such breach within thirty (30) days of the Notified Party’s actual receipt of said notice,

Page 12

ii. as to breaches that can be cured, but cannot be cured within thirty (30) days of the Notified Party’s actual receipt of said notice using reasonable diligence, commence (and notify the Notifying Party of its commencement) to cure such breach within thirty (30) days after its actual receipt of notice and thereafter diligently pursue all steps necessary to cure the breach as expeditiously as is reasonable under the circumstances and thereafter cure the breach (it being intended in connection with a breach not susceptible of being cured with due diligence within said thirty (30) day period that the time within which to cure the same shall be extended for such period as may be necessary to complete the same with all due diligence),

iii. notify the Notifying Party within thirty (30) days of its actual receipt of notice from the Notifying Party that it disputes that there has been a breach and submit the dispute for resolution in accordance with Article 12 hereof within ten days after it so notifies the Notifying Party;

and if such breach is determined to be of a material nature, then, subject to the other provisions of this Section, the Notifying Party may terminate this Lease upon notice to the Notified Party.

(b) If the Notified Party contests the existence of an alleged breach in accordance with Article 12 hereof, then this Agreement may not be terminated, and shall not terminate, under this Section until the arbitrators have rendered a final decision. In the event said final decision holds that the Notified Party was in breach and that such breach was of a material nature, then this Agreement shall terminate upon thirty (30) days notice from the Notifying Party if the Notified Party, within the time periods specified in subsection (a) (with said time periods running from the date of entry of such final decision) has not: (i) cured such breach, or (ii) as to breaches that due to their nature cannot be cured within thirty (30) days, diligently pursued all steps specified in subsection (a).

(c) Nothing in this Section shall preclude either party from seeking equitable remedies to protect their interests hereunder.

(d) Unless otherwise expressly provided herein, termination of this Agreement under this Section shall be without prejudice to any other rights or remedies to which the parties may be entitled, including the right to damages.

8.2. Termination and Surrender.

(a) This Agreement: (i) shall terminate automatically upon termination of any of the Lease and Option Agreements (other than upon termination of one or more Lease and Option Agreements on or prior to the First Lease Payment Date at the election of YCKM on account of the discovery of Defective Claims), (ii) may be terminated by written notice of the non-defaulting party in the event that the other party is in default pursuant to Section 8.1 hereof, (iii) may be terminated by mutual agreement of the parties, and (iv) shall terminate automatically on the Option Closing Date in the event of YCKM’s exercise of the Option.

(b) Upon termination of this Agreement, by default or otherwise, all rights, liabilities, and obligations of YCKM under this Agreement shall terminate except as expressly provided herein. For the avoidance of doubt, termination of this Agreement shall not terminate the obligations of YCKM under the royalties reserved by the Claimholders pursuant to the Lease and Option Agreements

Page 13

and the Royalty granted by the Claimholders to ANF and acknowledged by YCKM in Section 3.5 hereof.

(c) In the event of any controversy, the parties may, by mutual agreement, continue operations under this Agreement and YCKM shall make the payments provided for in this Agreement notwithstanding the existence of the controversy. Upon the resolution of the controversy, such payments or restitutions shall be made as required by the terms of the decision of the court or arbitrators, or otherwise.

(d) Upon termination of this Agreement prior to exercise of the Option, the Escrow Instructions shall terminate and the Mining Deeds shall be returned to the Claimholders.

8.3. Reassignment. If at any time following exercise of the Option by YCKM, YCKM intends to abandon any portion of the Mining Properties, YCKM shall send to ANF and the Claimholder(s) that previously owned such portion of the Mining Properties thirty (30) days prior written notice of YCKM’s intention to abandon along with a description of the Mining Properties to be abandoned. Commencing on the effective date of notice from YCKM of its intention to abandon such portion of the Mining Properties, the Claimholder(s) that previously owned such portion of the Mining Properties shall have fifteen (15) days in which to notify YCKM that it or they wish to reacquire that portion of the Mining Properties that YCKM is abandoning. Following the initial fifteen day period, if Claimholder(s) have not notified YCKM that they wish to reacquire any portion of the Mining Properties, YCKM shall send notice to ANF and ANF shall have an additional fifteen day period from the effective date of YCKM’s notice to notify YCKM that ANF wishes to acquire such portion of the Mining Properties. YCKM shall take all reasonable steps to facilitate the acquisition by Claimholder(s) and/or ANF any such portion of the Mining Properties for no additional consideration. If Claimholders and/or ANF reacquire any portion of the Mining Properties, as to that property so reacquired, all obligations of YCKM shall be terminated except for YCKM’s obligations under Section 4.1(b), and Section 6.5(b) relating to Data. If Claimholders and ANF fail to notify YCKM within the required periods, YCKM shall have the right to abandon such portion of the Mining Properties and YCKM’s obligations as to that portion of the abandoned Mining Properties shall cease, excepting the obligation to perform any and all mined land reclamation required with respect to such abandoned Mining Properties.

Any additional discovery shall only occur by agreement of the parties or as ordered by the arbitrators upon a finding of good cause.

12.6. Costs. Each party shall bear its own costs, expenses and attorney’s and party arbitrator fees; and one-half of the neutral arbitrator’s fees, provided that if court proceedings to stay litigation or compel arbitration are necessary, the party who unsuccessfully opposes such proceedings shall pay all reasonable associated costs, expenses, and attorney’s fees in connection with such court proceedings.

calendar quarter in which the same accrue. Royalty payments shall be by Miner's check, ACH or wire transfer, and shall be accompanied by a settlement sheet showing the quantities and grades of Minerals mined or extracted from the Mining Properties, saved and removed for sale or processing, proceeds of sale, costs, and other pertinent information in sufficient detail to explain the calculation of the royalty payment.

b. Depository Bank. Upon written request of Miner, ANF shall designate a bank to act as ANF's agent to receive from Miner all payments payable under the terms hereof, and all such payments may be made by paying or tendering the same to ANF, or to said bank for ANF's credit, which bank shall continue as the depository for all royalty payments hereunder regardless of changes of ownership of the Mining Properties, or rights to receive payments hereunder, subject only to the subsequent provisions in this Section 4.b. All charges of such depository bank shall be for ANF's account. A single payment or tender to said depository bank shall be made by mailing or by delivering a check, ACH or wire transfer, to it, and such a payment shall effectively and for all purposes whatsoever constitute full payment of the amount thereof to ANF to the same extent as if made directly. In the event ANF fails to name said bank upon the request of Miner, or in the event such bank (or any successor bank) should fail, liquidate or be succeeded by another bank, or for any reason fail or refuse to accept royalties, or should the owners of all rights to payments hereunder desire to designate another depository bank, then Miner shall not be held in default for failure to make payment or tender of payments until thirty (30) days after said persons shall deliver to Miner a proper, recordable instrument naming a bank as agent to receive such payments or tenders.

c. Objections to Payments. All royalty payments shall be considered final and in full satisfaction of all obligations of Miner with respect thereto unless ANF gives Miner written notice describing and setting forth a specific objection to the calculation thereof within sixty (60) days after receipt by ANF of the quarterly statement herein provided for. If ANF objects to a particular quarterly statement as herein provided, ANF shall, for a period of thirty (30) days after ANF's receipt of notice of such objection, have the right to have Miner's accounts and records relating to calculation of the quarterly statement in question audited by a certified public accountant acceptable to ANF and to Miner. Miner shall account for any deficits or excess in the payment made to ANF pursuant to the quarterly statement in question which may be confirmed by such an audit by adjusting the next quarterly statement following completion of such audit to account for such deficits or excess. If the variation between the amount of a particular royalty payment made to ANF hereunder as calculated by the audit provided for herein exceeds Five Percent (5%), Miner shall pay all costs of such audit. If such variation is Five Percent (5%) or less, ANF shall pay all costs of such audit. For the purpose of determining the amount of royalties payable hereunder all figures, accounts, and records used in connection with the calculation of royalties shall be determined in accordance with generally accepted accounting principles and from accounts maintained by Miner in connection with its operations upon the Mining Properties.

5. General

a. Commingling of Ores. Miner shall have the right of mixing or commingling, either underground, at the surface, or at processing plants or other treatment facilities, any ores, mine waters, leachates, pregnant liquors, pregnant slurries, or other products

Schedule H – Page 5

or compounds containing Minerals mined or extracted from the Mining Properties with any similar substances derived from other lands or properties; provided that Miner shall first weigh, sample and determine the wet weight, moisture content, dry weight, pay metal content, amenability and mill recovery rates for any such ores, products, or compounds containing Minerals mined or extracted from the Mining Properties before the same are so mixed or commingled.

b. Sampling, Assay, and Analysis. Any determination of weight, volume, moisture content, amenability, or pay metal content, and any sampling and analysis shall be made in accordance with sound mining and metallurgical practices and standard sampling and analysis procedures prevailing in the uranium mining and milling industry. ANF shall have the right to have a representative present at the time samples are taken. If Miner xxxxx or otherwise processes ore, leachates, pregnant liquors, or pregnant slurries or other compounds or products mined or extracted from the Mining Properties, ANF shall be furnished at ANF's request, a portion of all samples taken for analysis. Split samples shall by retained by Miner for later analysis by an independent referee selected by mutual agreement of the parties, and; in the event of a dispute concerning Miner's assay of samples, Royalty payments shall be based on the assay results determined by the independent referee. All statements or reports wherein Miner's assay of samples are set forth shall be conclusively presumed to be true and correct, unless, within sixty (60) days after such statements or reports are delivered to ANF, ANF makes written objection thereto and demands an assay by the independent referee; and unless such objection and demand is made within such sixty-day period, Miner shall have no duty to preserve the split samples after the end of such sixty-day period. The cost of the independent referee shall be paid by the party whose assay shows the greatest variance from that of the independent referee.

c. Waste Rock, Spoil and Tailings. The ore, mine waters, leachates, pregnant liquors, pregnant slurries, or other products or compounds of Minerals mined or extracted from the Mining Properties shall be the property of Miner subject to the Royalty as provided herein. Miner shall not be liable for mineral values lost in mining or processing pursuant to sound mining and metallurgical engineering practices. The Royalty shall be payable on only Minerals recovered prior to the time waste rock, spoil, tailings, or other mine waste and residue are first disposed of as such, and such waste rock, spoil, tailings, or other mine wastes and residue shall be the sole property of the Miner. Miner shall have the sole right to dump, deposit, sell, dispose of, or reprocess such waste rock, spoil, tailings, or other mine wastes and residues, and ANF shall have no claim or interest therein or to proceeds or mineral values recovered therefrom.

d. Pooling or Unitization. For the purpose of conducting in situ solution mining on the Mining Properties, Miner shall have the right to pool and combine acreage from the Mining Properties with other property at any time and from time to time as a recurring right, either before or after production, for exploratory, developmental or operating purposes. Miner shall promptly notify ANF of such action. In the event Miner shall elect to produce Minerals from such pooled acreage, Miner shall have the location of any such production drilling pattern accurately surveyed in the form of a rectangle containing all injection and production xxxxx to determine the position of the drilling pattern with respect to the boundary line of the Mining Properties, and shall furnish ANF a copy of such survey; provided that Miner shall have the sole discretion to determine the location, size and shape of any such drilling pattern. For the purpose of determining and allocating royalty hereunder, production of Minerals from the well or xxxxx

Schedule H – Page 6

involved in such drilling pattern shall be allocated pro rata on the basis of surface acreage within the drilling pattern of the Mining Properties and the other lands pooled therewith, determined in accordance with the survey required hereunder. It shall be conclusively presumed that the Minerals which are produced from any such pooled acreage are homogeneous and are produced uniformly within the boundaries of such drilling pattern, both as to quantity and quality.

e. Ownership. No change or division in the ownership of the Royalty or payment of proceeds attributable to the Royalty shall enlarge the obligations or diminish the rights of Miner. No change or division in ownership shall be binding on Miner until thirty (30) days after ANF has given Miner a certified copy of the recorded instrument evidencing the change or division.

IN WITNESS WHEREOF, Owner has executed and delivered this Royalty Deed the day and year first written above.
