3.6 Purchase Price Adjustment

(a) Purchaser shall cause Company to prepare and deliver to Sellers, as soon as practicable, and in any event within 30 days following the Closing Date: (i) an unaudited consolidated balance sheet of the Company as of the Calculation Time (the "Closing Balance Sheet") prepared in accordance with GAAP applied consistently with the past practices of the Company; (ii) a statement setting forth the calculation of the Working Capital of Company as of the Calculation Time determined by reference to the Closing Balance Sheet (the "Working Capital Statement"), which statement shall be calculated in accordance with GAAP and shall include the amount of the Company's Working Capital (the "Adjustment Amount") as of the Calculation Time, it being understood that a positive Working Capital amount will result in an equivalent positive Adjustment Amount and a negative Working Capital amount will result in an equivalent negative Adjustment Amount.

No reserves or other accruals shall be increased or created. Purchaser shall provide, or cause to be provided to Sellers, copies of all working papers resulting from, or used in connection with, the preparation of the Purchase Price Adjustment Documents.

(b) On or prior to the 10^th Business Day after Sellers' receipt of the Purchase Price Adjustment Documents (such 10 Business Day period, the "Objection Period"), either Seller may give Purchaser a written notice (the "Objection Notice") stating in reasonable detail that Seller's objections to the Purchase Price Adjustment Documents. Any Objection Notice shall specify in reasonable detail the dollar amount and nature of any objection and the basis therefor.

20

Except to the extent that either Seller makes a specific objection to a specific determination set forth on a Purchase Price Adjustment Document pursuant to the Objection Notice delivered to Purchaser within the Objection Period, the Purchase Price Adjustment Documents will be conclusive and binding upon the parties hereto for purposes of determining the adjustment in Section 3.6(d).

(c) If either Seller delivers a timely Objection Notice as described in Section 3.6(b), then Purchaser and Sellers will negotiate in good faith to resolve their disputes regarding the Purchase Price Adjustment Documents. If Purchaser and Sellers are unable to resolve all disputes regarding the Purchase Price Adjustment Documents on or prior to the 10^th day after Purchaser's receipt of the Objection Notice, then Sellers and Purchaser will retain an independent accounting firm (selected either by mutual agreement or, in the absence of mutual agreement, by random choice after eliminating any such firm which is conflicted or otherwise unable to participate) (an "Independent Accounting Firm"), to resolve the dispute as soon as practicable, and in any event within 20 days of its appointment. Each of Sellers, on the one hand, and Purchaser, on the other hand, shall provide to the Independent Accounting Firm its view of the correct amount of the Adjustment Amount and the constituent items forming part of the Working Capital Statement. The Independent Accounting Firm shall act as an expert and not as an arbitrator to determine, based solely on the written submissions of the parties and not by independent investigation, only the specific items under dispute by Sellers and Purchaser. The Independent Accounting Firm shall render a written report as to the resolution of the dispute and the resulting computation of the Adjustment Amount. The Adjustment Amount as determined by the Independent Accounting Firm will, absent manifest error, be conclusive and binding upon the parties hereto and will constitute the Adjustment Amount for all purposes of this Section 3.6. In resolving any disputed item, the Independent Accounting Firm: (x) shall be bound by the provisions of this Section 3.6(c); and (y) may not assign a value to any item greater than the greatest value for such item claimed by either Sellers or Purchaser or less than the smallest value for such item claimed by either Sellers or Purchaser. Where the Independent Accounting Firm determines that the Adjustment Amount should be increased by more than 15% from the amount contemplated in the Working Capital Statement delivered by Purchaser to Sellers, Purchaser shall pay all fees, costs and expenses of the Independent Accounting Firm in resolving the dispute, otherwise such fees, costs and expenses shall be the responsibility of Sellers.

(d) If there is a negative Adjustment Amount, Sellers shall pay such amount to Purchaser by wire transfer of immediately available funds. If there is a positive Adjustment Amount, Purchaser shall pay such amount to Sellers by wire transfer of immediately available funds. Any payment made pursuant to this Section 3.6(d) shall be made within two (2) Business Days (i) if no Objection Notice is delivered, after the Objection Period has expired, or (ii) if an Objection Notice is delivered, after all disputes are finally resolved pursuant to Section 3.6(c).

(e) Any payment made pursuant to Section 3.6(d) will be treated as an adjustment to the Estimated Purchase Price for all purposes, unless a contrary treatment is required by applicable Laws.

Notwithstanding any investigations made, or knowledge acquired, by Purchaser prior to Closing, each Seller, individually and not jointly and severally, shall defend and indemnify Purchaser and hold it harmless from and against any liability of the Company for Taxes for all taxable periods (or in the case of Straddle Periods, the portion thereof) ending on or before the Closing Date. For the purposes of this Section 7.4, in the case of any Taxes that are imposed on a periodic basis and are payable for a Straddle Period, the portion of such Tax related to the portion of such Straddle Period ending on and including the Closing Date shall (A) in the

50

case of any Taxes other than Taxes based upon or related to gross receipts, sales or use taxes or income, be deemed to be the amount of such Tax for the entire relevant Straddle Period multiplied by a fraction, the numerator of which is the number of days in the relevant Straddle Period ending on and including the Closing Date and the denominator of which is the number of days in the relevant Straddle Period, and (B) in the case of any Tax based upon or related to gross receipts, sales or use or income, be deemed equal to the amount which would be payable if the relevant Straddle Period ended on and included the Closing Date.

7.5 Change of Control Payment Indemnity

Notwithstanding any investigations made, or knowledge acquired, by Purchaser prior to Closing, each Seller, individually and not jointly and severally, shall defend and indemnify Purchaser and hold it harmless from and against any liability of the Company in respect of Change of Control Payments.

7.6 Environmental Indemnity

(a) Each Seller, individually and not jointly and severally, shall defend and indemnify and save harmless each of Purchaser, its managers, officers, employees and agents and any successor to Purchaser and its managers, officers, employees and agents from and against all Losses suffered or incurred by any such Person as a result of or arising directly or indirectly out of or in connection with any: (i) event occurring or conditions existing at or prior to the Closing Date relating to the Business, the Company, the Owned Property, the Leased Mining Claims and Leased Real Property which as at the Closing Date constitutes a violation of, or gives rise to liability under, Environmental Laws; or (ii) any generation, manufacture, processing, distribution, use, presence, treatment, storage, disposal, Release, transport or handling of any Hazardous Substance in, on, under or from any Owned Property, the Leased Mining Claims, Leased Real Property or Former Property, whether by the Company, a Seller or any other Person prior to the Time of Closing and whether or not known at the Time of Closing (except as a result of or arising directly or indirectly out of or in connection with any re-disturbance after the Time of Closing of the heap xxxxx pad and associated facilities described on Schedule 4.33(a)).

(b) Purchaser shall defend, indemnify and save harmless each of Sellers and their respective Affiliates, and their managers, officers, employees and agents and any successors and their respective managers, officers, employees and agents from and against all Losses suffered or incurred by any such Person as a result of or arising directly or indirectly out of or in connection with any: (i) Release of any Hazardous Substance in, on, under or from any Owned Property, the Leased Mining Claims, Leased Real Property or Former Property, whether by the Company or Purchaser after the Time of Closing, or (ii) re-disturbance after the Time of Closing of the heap xxxxx pad and associated facilities described on Schedule 4.33(a).

7.7 Assignability of Environmental Indemnification

Purchaser may, at any time and from time to time, assign all or any part of the benefit of the indemnity set out in Section 7.6(a) in respect of all or any part of the Business, the Owned Property, the Leased Mining Claims, the Leased Real Property or the Former Property to any purchaser of, or lender to Purchaser in respect of the Company, the Business, the Owned

51

Property, the Leased Mining Claims or Leased Real Property, by delivering a notice in writing to Sellers setting out Purchaser's intention to assign all or part of the benefit of the indemnity and the identity of the Person or Persons to whom the assignment is to be made. Upon any such assignment, each Seller shall be bound to indemnify the Person or Persons named in such notice to the extent of the assignment of the indemnity as if such Person or Persons were a party to this Agreement as Purchaser. No such assignment shall relieve such Seller of the continuing obligation to indemnify under the indemnity and such obligation shall continue unaffected by the assignment. Any such assignee may make a further assignment in accordance with the foregoing provisions, as if all references therein to Purchaser were to such assignee.

7.8 Monetary Limitation of Liability; Effect of Materiality Qualifiers

(a) An Indemnified Party shall not be entitled to require payment of any amount by the Indemnifying Party on the indemnities contained in Sections 7.2, 7.3 or 7.6, as applicable, until the aggregate of all such amounts for which the Indemnified Party would otherwise be entitled to require payment under such Sections exceeds $500,000 (the "Deductible Amount"). Once the Deductible Amount has been exceeded, the Indemnified Party shall be entitled to require payment on such indemnities only on that portion of Losses that exceeds the Deductible Amount.

(b) An Indemnified Party shall not be entitled to require payment of amounts by the Indemnifying Party on the indemnities contained in Sections 7.2 and 7.6 in the aggregate, or the indemnities contained in Section 7.3, as the case may be, in excess of $18,750,000 (the "Cap Amount"). With respect to the Cap Amount, neither Seller shall be obligated to make payments in excess of its proportionate share of the Cap Amount, such proportion to be based on such Seller's Membership Interest immediately prior to the Closing.

(c) Where a Claim pursuant to Section 7.2 or Section 7.3 is predicated on an underlying representation and warranty or covenant that is qualified by a reference to "materiality" or "Material Adverse Effect", the underlying representation and warranty or covenant shall be read as if it did not contain such qualifier.

7.9 Notice of Claim

(a) A party that may be entitled to make a claim for indemnification (a "Claim") under this Agreement (the "Indemnified Party") shall give written notification to the other party (the "Indemnifying Party") of such Claim (a "Notice of Claim") promptly upon becoming aware of the Claim, but in no event later than the relevant date, if any, specified in Section 7.10. The Notice of Claim shall specify whether the Claim arises as a result of a claim by a Person (other than a party to this Agreement) against the Indemnified Party (a "Third-Party Claim") or whether the Claim does not so arise (a "Direct Claim"), and shall also specify with reasonable particularity, to the extent that the information is available, the factual basis for the Claim and the amount of the Claim.

(b) If an Indemnified Party fails to provide the Indemnifying Party with a Notice of Claim promptly as required by Section 7.9(a), the Indemnifying Party shall be relieved of the obligation to pay damages to the extent it can show that it was prejudiced in its defence of the

52

Claim or in proceeding against a third party who would have been liable to it by the fact of the delay, but the failure to provide such Notice of Claim promptly shall not otherwise release the Indemnifying Party from its obligations under this Article 7.

(c) If the date by which a Notice of Claim must be given as set out in Section 7.10 in respect of a breach of representation and warranty has passed without any Notice of Claim having been given to the Indemnifying Party, then the related Claim shall be forever extinguished, notwithstanding that by the date specified in Section 7.10 the Indemnified Party did not know, and in the exercise of reasonable care could not have known, of the existence of the Claim.

7.10 Time Limits for Notice of Claim

(a) Sellers shall not be required to indemnify or save harmless Purchaser pursuant to Section 7.2(a) unless Purchaser shall have provided to such Seller a Notice of Claim within the following time limits:

(i) with respect to the representations and warranties set out in Sections 4.1 through 4.5 and 4.10, at any time after Closing;

(ii) with respect to the representations and warranties set out in Section 4.29, not later than the day that is 60 days after the expiration of the period, if any, during which an assessment, reassessment or other form of recognized written demand assessing liability for Tax, interest or penalties under applicable legislation in respect of any taxation year to which such representations and warranties relate could be issued to the Company under such legislation;

(iii) with respect to the representations and warranties set out in Section 4.33, not later than the third anniversary of the Closing Date;

(iv) with respect to a claim for any breach of any of the representations and warranties contained in this Agreement or in any agreement, instrument, certificate or other document executed or delivered pursuant hereto involving fraud, at any time after Closing; and

(v) with respect to all other representations and warranties, not later than the second anniversary of the Closing Date.

(b) Such Seller shall not be required to indemnify or save harmless Purchaser pursuant to Section 7.4 unless Purchaser shall have provided to such Seller a Notice of Claim not later than the day that is 60 days after the expiration of the limitation period within which the relevant Governmental Body may make a claim against the Company for Taxes in respect of which the indemnity in Section 7.4 is given.

(c) Purchaser shall not be required to indemnify or save harmless Sellers pursuant to Section 7.3(a) unless Sellers shall have provided to Purchaser a Notice of Claim not later than the second anniversary of the Closing Date.

53

(d) Such Seller shall not be required to indemnify or save harmless Purchaser pursuant to Section 7.6 unless Purchaser shall have provided to Sellers a Notice of Claim not later than the third anniversary of the Closing Date.

7.11 Limitation Periods for Claims for Breach of Representations and Warranties and Taxes Owing

Notwithstanding the provisions of any statute, the period within which an Indemnified Party may commence a proceeding in respect of a Claim for which a Notice of Claim is required to be, and has been, given in accordance with Section 7.10, shall be 18 months from the last date upon which such Notice of Claim is permitted to be delivered thereunder, and any applicable limitation period is hereby so extended to the fullest extent permitted by Law.

7.12 Direct Claims

With respect to any Direct Claim, following receipt of notice from the Indemnified Party of the Claim, the Indemnifying Party shall have 45 days to make such investigation of the Claim as is considered necessary or desirable. For the purpose of such investigation, the Indemnified Party shall make available to the Indemnifying Party the information relied upon by the Indemnified Party to substantiate the Claim, together with all such other information as the Indemnifying Party may reasonably request. If both parties agree at or prior to the expiration of such 45-day period (or any mutually agreed upon extension thereof) to the validity and amount of such Claim, the Indemnifying Party shall immediately pay to the Indemnified Party the full agreed-upon amount of the Claim, failing which the matter shall be referred to binding arbitration in such manner as the parties may agree or shall be determined by a court of competent jurisdiction.

7.13 Third-Party Claims

(a) The Indemnifying Party shall have the right, at its expense, to participate in or assume control of the negotiation, settlement or defence of any Third-Party Claim for damages and if the Indemnifying Party assumes control, it shall reimburse the Indemnified Party for all of the Indemnified Party's reasonable out-of-pocket expenses prior to the time the Indemnifying Party assumed control. If the Indemnifying Party elects to assume such control, the Indemnified Party shall have the right to participate in the negotiation, settlement or defence of such Third-Party Claim and to retain counsel to act on its behalf, provided that the fees and disbursements of such counsel shall be paid by the Indemnified Party unless the named parties to any action or proceeding include both the Indemnifying Party and the Indemnified Party and representation of both the Indemnifying Party and the Indemnified Party by the same counsel would be inappropriate due to actual or potential differing interests between them (such as the availability of different defences).

(b) If the Indemnifying Party, having elected to assume such control, thereafter fails to defend the Third-Party Claim within a reasonable time, the Indemnified Party shall be entitled to assume such control and the Indemnifying Party shall be bound by the results obtained by the Indemnified Party with respect to such Third-Party Claim.

54

(c) If any Third-Party Claim is of a nature such that the Indemnified Party is required by applicable Law to incur losses or make a payment to any Person not a party to this Agreement (a "Third Party") with respect to the Third-Party Claim before the completion of settlement negotiations or related legal proceedings, the Indemnified Party may incur such Losses or make such payment and the Indemnifying Party shall, forthwith after demand by the Indemnified Party, reimburse the Indemnified Party for such payment. If the amount of any liability of the Indemnified Party under such Third-Party Claim, as finally determined, is less than the amount that was paid by the Indemnifying Party to the Indemnified Party, the Indemnified Party shall, forthwith after the receipt of the difference from the Third Party, pay the amount of such difference, together with any interest thereon paid by the Third Party to the Indemnified Party, to the Indemnifying Party. In addition, the Indemnifying Party shall post all security required by any court, regulatory body or other authority having jurisdiction, including for purposes of enabling the Indemnifying Party to contest any Third-Party Claim.

(d) If the Indemnifying Party fails to assume control of the defence of any Third-Party Claim or defaults in respect of any of its obligations under this Section 7.13 with respect thereto, the Indemnified Party shall have the exclusive right to contest the amount claimed and may settle and pay the same on 14 days' prior written notice to the Indemnifying Party and the Indemnifying Party shall, thereupon, be deemed to have agreed that such settlement is reasonable and may be agreed to by the Indemnified Party and all other Persons liable in respect of the Third-Party Claim unless within such 14-day period the Indemnifying Party notifies the Indemnified Party that it is assuming or reassuming control of such defence and thereafter assumes or reassumes such control and does not default.

(e) The Indemnified Party and the Indemnifying Party shall co-operate fully with each other with respect to Third-Party Claims, and shall keep each other fully advised with respect thereto (including supplying copies of all relevant documentation promptly as it becomes available).

7.14 Exclusivity

Neither Sellers, on the one hand, nor Purchaser, on the other hand, may make any claim for damages in respect of this Agreement or any agreement, certificate or other document delivered pursuant hereto, or in respect of any breach or termination thereof, against the other party hereto except by making a Claim pursuant to and in accordance with this Article 7. The provisions of this Section 7.14 shall survive any termination of this Agreement.

In the event of the termination of this Agreement in accordance with this Article 8, this Agreement shall thereafter become void and have no effect, and none of Sellers and Purchaser shall have any liability to Sellers, Purchaser or their respective Affiliates, or their respective partners, managers, directors, officers or employees, as applicable, pursuant to this Agreement except for the obligations of Sellers and Purchaser contained in this Section 8.5, Section 8.6, Article 10 (and any related definitional provisions set forth in Article 1) or Section 6.3. Notwithstanding the foregoing, nothing in this Section 8.5 shall relieve Sellers or Purchaser from liability for any willful breach of this Agreement that arose prior to such termination.

8.6 Termination Payment

9.2 Responding to an Acquisition Proposal

Notwithstanding Section 9.1, if at any time prior to the Closing, Sellers or the Company receive from a Person a written proposal for an Acquisition Transaction (an "Acquisition Proposal"), Sellers may engage in or participate in discussions or negotiations with such Person regarding such Acquisition Proposal, and may provide copies of, access to or disclosure of confidential information, properties, facilities, books or records of the Company for a maximum of seven Business Days from the date that such access or disclosure is first given, if and only if:

(a) the board of directors of either Solitario or Xxx Gold first determines in good faith, after consultation with its financial advisors and its outside legal counsel, that such Acquisition Proposal: (i) is or could reasonably be expected to result in a transaction that is more favourable, from a financial point of view, to the shareholders of either Solitario or Xxx Gold than the transaction provided for in this Agreement; (ii) constitutes or could reasonably be expected to constitute or lead to a Superior Proposal; and (iii) after consultation with its outside legal counsel, that the failure to engage in such discussions or negotiations would be inconsistent with its fiduciary duties;

(b) such Person was not restricted from making such Acquisition Proposal pursuant to an existing standstill or similar restriction with the Sellers;

(c) Sellers have been, and continue to be, in compliance with their obligations under this Article 9;

(a) Sellers have been, and continue to be, in compliance with their obligations under this Article 9;

(b) Sellers have delivered to Purchaser a written notice of the determination of the board of directors of either Solitario or Xxx Gold that such Acquisition Proposal

59

constitutes a Superior Proposal and of the intention of Sellers to enter into such definitive agreement, together with a written notice from such board regarding the value and financial terms that such board, in consultation with its financial advisors, has determined should be ascribed to any non-cash consideration offered under such Acquisition Proposal (the "Superior Proposal Notice");

(c) Sellers have provided Purchaser with a copy of the proposed definitive agreement for the Superior Proposal;

(d) at least three Business Days have elapsed from the date that is the later of the date on which Purchaser received the Superior Proposal Notice and a copy of the proposed definitive agreement for the Superior Proposal from Sellers;
