Each Party hereto will act in a manner that is consistent with the Parties' intention that the Arrangement be treated as a reorganization within the meaning of Section 368(a) of the Code for all U.S. federal income tax purposes, and will not take any action, or knowingly fail to take any action, if such action or failure to act would reasonably be expected to prevent the Arrangement from qualifying as a reorganization within the meaning of Section 368(a) of the Code.

2.13 Employees and Change of Control Payments

(a)

The Parties agree that all change of control payments pursuant to the Employment Agreements that are payable as a result of the Arrangement are disclosed in Section 27 of the Zazu Disclosure Letter and will be paid by Zazu to the applicable executive officer, employee or consultant of Zazu entitled thereto in accordance with the schedule included in Section 27 of the Zazu Disclosure Letter, in exchange for the execution of full and final releases in respect of the change of control entitlements in favour of Zazu and in form and substance satisfactory to Solitario, acting reasonably. To the extent that current agreements are not consistent with the information in Section 27 of the Zazu Disclosure Letter, Zazu covenants to amend such agreements or provide waivers where necessary to achieve consistency with the information in Section 27 of the Zazu Disclosure Letter.

(b)

Zazu will be exclusively responsible and will pay for any withholding obligations of Taxes pursuant to the Tax Act from any amounts paid for the payments contemplated in Section 2.13(a).

2.14 Withholding Taxes

Zazu, Solitario and the Depositary will be entitled to deduct and withhold from any consideration otherwise payable or deliverable to any Zazu Shareholder or Zazu Optionholder under the Plan of Arrangement (including any payment to Dissenting Zazu Shareholders) such amounts as Zazu, Solitario or the Depositary may be required or permitted to deduct and withhold with respect to such payment or deliverable under the Tax Act, the Code, and the rules and regulations promulgated thereunder, or any provision of any provincial, state, local or foreign tax Law. For the purposes hereof, all such withheld amounts will be treated as having been paid to the person in respect of which such deduction and withholding was made on account of the obligation to make payment to such person hereunder, provided that such deducted or withheld amounts are actually remitted to the appropriate Governmental Authority by or on behalf of Zazu, Solitario or the Depositary, as the case may be. To the extent necessary, such deductions and withholdings may be effected by selling any Solitario Shares to which any such person may otherwise be entitled under the Plan of Arrangement, on such terms as Solitario reasonably determines, and any amount remaining following the sale, deduction and remittance will be paid to the person entitled thereto as soon as reasonably practicable.

it will use commercially reasonable efforts to satisfy (or cause the satisfaction of) the conditions precedent to its obligations hereunder as set forth in Article 7 hereof to the extent the same is within its control and to take, or cause to be taken, all other action and to do, or cause to be done, all other things necessary and commercially reasonable to permit the completion of the Arrangement in accordance with its obligations under this Agreement, the Plan of Arrangement and applicable Laws and cooperate with the other Party in connection therewith, including using its commercially reasonable efforts to (i) obtain all approvals required to be obtained by it, (ii) effect or cause to be effected all necessary registrations, filings and submissions of information requested by Governmental Authorities required to be effected by it in connection with the Arrangement, (iii) oppose, lift or rescind any injunction or restraining order against it or other order or action against it seeking to stop, or otherwise adversely affecting its ability to make and complete, the Arrangement and (iv) cooperate with the other Party in connection with the performance by it of its obligations hereunder;

(b)

it will use commercially reasonable efforts not to take or cause to be taken any action which is inconsistent with this Agreement or which would reasonably be expected to prevent or significantly impede or materially delay the completion of the Arrangement;

(c)

it will extend the expiration date of any Zazu Options held by any Zazu directors, employees and consultants who are terminated or who resigns as a result of the completion of the Arrangement until the earlier of the expiration date as provided in such Zazu Option or 18 months from the Effective Date; and

(d)

it will use commercially reasonable efforts to execute and do all acts, further deeds, things and assurances as may be required in the reasonable opinion of the other Party's legal counsel to permit the completion of the Arrangement.

4.7 Covenants Related to Regulatory Approvals

Each Party, as applicable to that Party, covenants and agrees with respect to obtaining all Regulatory Approvals required for the completion of the Arrangement that, subject to the terms and conditions of this Agreement, until the earlier of the Effective Time and the time that this Agreement is terminated in accordance with its terms:

(a)

each Party will use its commercially reasonable efforts to obtain all required Regulatory Approvals, and will cooperate with the other Party in connection with all Regulatory Approvals sought by the other Party;

(b)

each Party will use commercially reasonable efforts to respond promptly to any request or notice from any Governmental Authority requiring that Party to supply additional information that is relevant to the review of the transactions contemplated by this Agreement in respect of obtaining or concluding the Regulatory Approvals sought by either Party, and each Party will cooperate with the other Party and will furnish to the other Party such information and assistance as a Party may reasonably request in connection with preparing any submission or responding to such request or notice from a Governmental Authority;

(c)

each Party will permit the other Party an opportunity to review in advance any proposed substantive applications, notices, filings, submissions, undertakings, correspondence and communications (including responses to requests for information and inquiries from any Governmental Authority or the Commissioner) in respect of obtaining or concluding all required Regulatory Approvals, and will provide the other Party with a reasonable opportunity to comment thereon and agree to consider those comments in good faith, and each Party will provide the other Party with any substantive applications, notices, filings, submissions, undertakings or other substantive correspondence provided to a Governmental Authority, or any substantive communications received from a Governmental Authority, in respect of obtaining or concluding the required Regulatory Approvals; and

(d)

each Party will keep the other Party reasonably informed on a timely basis of the status of discussions relating to obtaining or concluding the required Regulatory Approvals sought by such Party and, for greater certainty, no Party will participate in any substantive meeting (whether in person, by telephone or otherwise) with a Governmental Authority in respect of obtaining or concluding the required Regulatory Approvals, unless it advises the other Party in advance and, to the extent permitted by such Governmental Authority, gives such other Party an opportunity to attend.

4.8 Indemnification and Insurance

(a)

The Parties agree that all rights to indemnification existing in favour of the present and former directors and officers of Zazu (each such present or former director or officer of Zazu being herein referred to as an "Indemnified Party" and such persons collectively being referred to as the "Indemnified Parties") as provided by the by-laws of Zazu and any Contracts or agreements to which Zazu is a party and in effect as of the date hereof, and, as of the Effective Time, will survive and will continue in full force and effect and without modification, and Zazu and any successor to Zazu (including any Surviving Corporation) will continue to honour such rights of indemnification and indemnify the Indemnified Parties pursuant thereto, with respect to actions or omissions of the Indemnified Parties occurring prior to the Effective Time, for six years following the Effective Date.

(b)

Solitario acknowledges that Zazu may purchase run-off directors’ and officers’ liability insurance, at a cost not exceeding 200% of Zazu’s current annual aggregate premium for directors’ and officers’ liability policies currently maintained by Zazu, providing coverage for a period of up to six years from the Effective Date with respect to claims arising from or related to facts or events which occur on or prior to the Effective Date.

(c)

Zazu shall act as agent and trustee of the benefits of the foregoing the Indemnified Parties for the purpose of this Section 4.8 and this Section 4.8 shall survive the execution and delivery of this Agreement and the completion of the Arrangement and shall be enforceable against Solitario by the Indemnified Persons.

4.9 Reorganization

(a)

Zazu will affect such reorganization of its business, operations, subsidiaries and assets or such other transactions (each, a "Pre-Acquisition Reorganization") as Solitario may reasonably request prior to the Effective Date, and the Plan of Arrangement, if required, will be modified accordingly; provided, however, that Zazu need not effect a Pre-Acquisition Reorganization which would impede or materially delay the consummation of the Arrangement.

(b)

Without limiting the foregoing and other than as set forth in clause (a) above, Zazu will use its commercially reasonable efforts to obtain all necessary consents, approvals or waivers from any persons to effect each Pre-Acquisition Reorganization, and Zazu will cooperate with Solitario in structuring, planning and implementing any such Pre-Acquisition Reorganization. Solitario will provide written notice to Zazu of any proposed Pre-Acquisition Reorganization at least ten Business Days prior to the date of the Zazu Meeting. In addition, the Parties agree:

(i)

any Pre-Acquisition Reorganization will not unreasonably interfere in Zazu's material operations prior to the Effective Time;

(ii)

any Pre-Acquisition Reorganization will not require Zazu to contravene any applicable Laws, its organizational documents or any Zazu Material Contract; and

(iii)

Zazu will not be obligated to take any action that could result in any Taxes being imposed on, or any adverse Tax or other consequences to, any Zazu Shareholder incrementally greater than the Taxes or other consequences to such party in connection with the consummation of the Arrangement in the absence of any Pre-Acquisition Reorganization.

(c)

Solitario acknowledges and agrees that the planning for and implementation of any Pre-Acquisition Reorganization will not be considered a breach of any covenant under this Agreement and will not be considered in determining whether a representation or warranty of Zazu hereunder has been breached. Solitario and Zazu will work cooperatively and use commercially reasonable efforts to prepare prior to the Effective Time all documentation necessary and do such other acts and things as are necessary to give effect to such Pre-Acquisition Reorganization. For greater certainty, Zazu will not be liable for the failure of Solitario to benefit from any anticipated Tax efficiency as a result of a Pre-Acquisition Reorganization.

(d)

If the Arrangement is not completed, Solitario shall reimburse Zazu for all reasonable costs and expenses including reasonable legal fees and disbursements incurred in connection with the Pre-Acquisition Reorganization.

4.10 Disclosure Letters

Each Party acknowledges and agrees that the Zazu Disclosure Letter, the Solitario Disclosure Letter and all information contained in the Zazu Disclosure Letter and the Solitario Disclosure Letter, respectively, is confidential information and may not be disclosed unless (i) it is required to be disclosed pursuant to Law unless such Law permits the Parties to refrain from disclosing the information for confidentiality or other purposes or (ii) a Party needs to disclose it in order to enforce or exercise its rights under this Agreement.

Article 5
ADDITIONAL AGREEMENTS

5.1 Acquisition Proposals

(a)

Except as expressly contemplated by this Agreement, until the earlier of the Effective Time or the date, if any, on which this Agreement is terminated pursuant to Section 6.1, Zazu will not and will cause its Representatives to not, directly or indirectly through any other person:

(i)

make, initiate, assist, solicit, promote, entertain or encourage (including by way of furnishing or affording access to information or any site visit or entering into any oral or written form of agreement, arrangement or understanding), or take any other action that facilitates, directly or indirectly, any inquiries or the making of any proposal or offer with respect to an Acquisition Proposal or that reasonably could be expected to constitute or lead to an Acquisition Proposal; or

(ii)

participate, directly or indirectly, in any discussions or negotiations with, furnish information to, or otherwise co-operate in any way with, any person (other than Solitario and its subsidiaries) regarding an Acquisition Proposal or that reasonably could be expected to constitute or lead to an Acquisition Proposal, provided, however, that Zazu will be entitled to advise such person of the existence of this Agreement or advise such person that their proposal does not constitute a Superior Proposal and is not reasonably expected to constitute or lead to a Superior Proposal; or

(iii)

remain neutral with respect to, or agree to, approve or recommend, or propose publicly to agree to, approve or recommend any Acquisition Proposal (it being understood that publicly taking no position or a neutral position with respect to an Acquisition Proposal for a period exceeding two Business Days after such Acquisition Proposal has been publicly announced will be deemed to constitute a violation of this Section 5.1(a)(iii)); or

(iv)

make or propose publicly to make a Change of Recommendation; or

(v)

accept, enter into, or propose publicly to accept or enter into, any agreement, understanding or arrangement effecting or related to any Acquisition Proposal or potential Acquisition Proposal (other than an Acceptable Confidentiality Agreement permitted by and in accordance with Section 5.1(c)); or

(vi)

make any public announcement or take any other action inconsistent with, or that could reasonably be likely to be regarded as detracting from, the approval, recommendation or declaration of advisability of the Zazu Board of the transactions contemplated hereby.

(b)

Zazu and its Representatives and its subsidiaries and their Representatives will immediately cease and cause to be terminated any solicitation, encouragement, discussion or negotiation with any person (other than Solitario and its subsidiaries) conducted heretofore by Zazu or any of its Representatives or its subsidiaries or any of their Representatives with respect to any Acquisition Proposal and, in connection therewith, Zazu will discontinue access to any of its confidential information, including access to any data room, virtual or otherwise, to any person (other than access by Solitario and its Representatives).

(c)

Notwithstanding anything to the contrary contained in Section 5.1(a), in the event that Zazu receives a bona fide written Acquisition Proposal from any person after the date hereof and prior to the Zazu Meeting that was not solicited by Zazu, that did not otherwise result from a breach of this Section 5.1 and where such person making the Acquisition Proposal was not restricted from making such Acquisition Proposal pursuant to an existing standstill or similar restriction, and subject to Zazu's compliance with Section 5.1(d), Zazu and its Representatives may (i) furnish information with respect to it to such person pursuant to an Acceptable Confidentiality Agreement, provided that (x) Zazu provides a copy of such Acceptable Confidentiality Agreement to Solitario promptly upon its execution and prior to furnishing any such information; and (y) Zazu contemporaneously provides to Solitario any non-public information concerning Zazu that is provided to such person which was not previously provided to Solitario or its Representatives, and (ii) participate in any discussions or negotiations regarding such Acquisition Proposal; provided, however, that, prior to taking any action described in clauses (i) or (ii) above, the Zazu Board determines in good faith, after consultation with its financial advisors and outside legal counsel, that such Acquisition Proposal constitutes or would be reasonably expected to constitute or lead to a Superior Proposal. Notwithstanding the foregoing, nothing in this Section 5.1(c) shall prevent Zazu from contacting a person who makes an unsolicited Acquisition Proposal to clarify the terms of such Acquisition Proposal.

(d)

Zazu will promptly (and, in any event, within 24 hours) notify Solitario, at first orally and thereafter in writing, of any Acquisition Proposal (whether or not in writing) received by Zazu, any inquiry received by Zazu that could reasonably be expected to lead to an Acquisition Proposal, or any request received by Zazu for non-public information relating to Zazu in connection with an Acquisition Proposal or for access to the properties, books or records of Zazu by any person that informs Zazu that it is considering making an Acquisition Proposal, and such notice will include a copy of the Acquisition Proposal, a description of the material terms and conditions of such inquiry or request and the identity of the person making such Acquisition Proposal, inquiry or request, and promptly provide to Solitario such other information concerning such Acquisition Proposal, inquiry or request as Solitario may reasonably request. Zazu will keep Solitario promptly and fully informed of the status and details (including all amendments) of any such Acquisition Proposal, inquiry or request.

(e)

Except as expressly permitted by this Section 5.1, neither the Zazu Board, nor any committee thereof will permit Zazu to accept or enter into any Acquisition Agreement requiring Zazu to abandon, terminate or fail to consummate the Arrangement or providing for the payment of any break, termination or other fees or expenses to any person proposing an Acquisition Proposal in the event that Zazu completes the transactions contemplated hereby or any other transaction with Solitario or any of its affiliates.

(f)

Notwithstanding Section 5.1, in the event Zazu receives a bona fide written Acquisition Proposal that is a Superior Proposal from any person after the date hereof and prior to the Zazu Meeting, then the Zazu Board may, prior to the Zazu Meeting, withdraw, modify, qualify or change in a manner adverse to Solitario its approval or recommendation of the Arrangement and/or approve or recommend such Superior Proposal or enter into an Acquisition Agreement with respect to such Superior Proposal but only if:

(i)

Zazu has given written notice to Solitario that it has received such Superior Proposal and that the Zazu Board has determined that (x) such Acquisition Proposal constitutes a Superior Proposal and (y) the Zazu Board intends to withdraw, modify, qualify or change in a manner adverse to Solitario its approval or recommendation of the Arrangement (including the recommendation that the Zazu Shareholders vote in favour of the Arrangement Resolution), and/or enter into an Acquisition Agreement with respect to such Superior Proposal in each case promptly following the making of such determination, together with a summary of the material terms of any proposed Acquisition Agreement or other agreement relating to such Superior Proposal (together with a copy of such agreement and any ancillary agreements) to be executed with the person making such Superior Proposal;

(ii)

a period of five full Business Days (such period being the "Superior Proposal Notice Period") will have elapsed from the date Solitario received the notice from Zazu referred to in Section 5.1(f)(i), together with the summary of material terms and copies of agreements referred to therein. During the Superior Proposal Notice Period, Solitario will have the right, but not the obligation, to propose to amend the terms of this Agreement and the Arrangement;

(iii)

Zazu did not breach any provision of this Section 5.1 in connection with the preparation or making of such Acquisition Proposal and Zazu has complied with the other terms of this Section 5.1(f);

(iv)

the Zazu Board will have determined in accordance with Section 5.1(g) that such Acquisition Proposal remains a Superior Proposal compared to the Arrangement as proposed to be amended by Solitario;

(v)

Zazu concurrently terminates this Agreement pursuant to Section 6.1(d)(i); and

(vi)

Zazu has previously, or concurrently will have, paid to Solitario the Termination Fee.

(g)

The Zazu Board will review in good faith any offer made by Solitario to amend the terms of this Agreement and the Arrangement in order to determine, in consultation with its financial advisors and outside legal counsel, whether the proposed amendments would, upon acceptance, result in the Acquisition Proposal previously constituting a Superior Proposal ceasing to be a Superior Proposal. Zazu agrees that, subject to Zazu's disclosure obligations under applicable Securities Laws, the fact of the making of, and each of the terms of, any such proposed amendments will be kept strictly confidential and will not be disclosed to any person (including without limitation, the person having made the Superior Proposal), other than Zazu's Representatives, without Solitario's prior written consent. If the Zazu Board determines that such Acquisition Proposal would cease to be a Superior Proposal as a result of the amendments proposed by Solitario, Zazu will forthwith so advise Solitario and will promptly thereafter accept the offer by Solitario to amend the terms of this Agreement and the Arrangement and the Parties agree to take such actions and execute such documents as are necessary to give effect to the foregoing. If the Zazu Board continues to believe in good faith, after consultation with its financial advisors and outside legal counsel, that such Acquisition Proposal remains a Superior Proposal and therefore rejects Solitario's offer to amend this Agreement and the Arrangement, if any, Zazu may, subject to compliance with the other provisions hereof, terminate this Agreement in accordance with Section 6.1(d)(i) to enter into an Acquisition Agreement in respect of such Superior Proposal.

(h)

Each successive modification of any Superior Proposal will constitute a new Superior Proposal for the purposes of Section 5.1(f) and will require a new five full Business Day Superior Proposal Notice Period from the date described in Section 5.1(f)(ii) with respect to such new Superior Proposal. If the Zazu Meeting is scheduled to occur during a Superior Proposal Notice Period, upon the request of Solitario, Zazu will, adjourn or postpone the Zazu Meeting to (i) a date specified by Solitario that is not later than six Business Days after the date on which the Zazu Meeting was originally scheduled to be held, or (ii) if Solitario does not specify such date to the sixth day after the date on which the Zazu Meeting was originally scheduled to be held.

(i)

The Zazu Board will reaffirm its recommendation in favour of the Arrangement by news release promptly after (A) the Zazu Board has determined that any Acquisition Proposal is not a Superior Proposal if the Acquisition Proposal has been publicly announced or made; or (B) the Zazu Board makes the determination referred to in Section 5.1(g) that an Acquisition Proposal that has been publicly announced or made and which previously constituted a Superior Proposal has ceased to be a Superior Proposal. Solitario will be given a reasonable opportunity to review and comment on the form and content of any such news release. Such news release will state that the Zazu Board has determined that such Acquisition Proposal is not a Superior Proposal.

(j)

Zazu will not become a party to any Contract with any person subsequent to the date hereof that limits or prohibits Zazu from (x) providing or making available to Solitario and its affiliates and Representatives any information provided or made available to such person or its officers, directors, employees, consultants, advisors, agents or other representatives (including solicitors, accountants, investment bankers and financial advisors) pursuant to any confidentiality agreement described in this Section 5.1 or (y) providing Solitario and its affiliates and Representatives with any other information required to be given to it by Zazu under this Section 5.1.

(k)

Zazu agrees (i) not to release any persons from, or terminate, modify, amend or waive the terms of, any confidentiality agreement or standstill agreement or standstill provisions in any such confidentiality agreement that Zazu entered into prior to the date hereof, (ii) to promptly and diligently enforce all standstill, non- disclosure, non-disturbance, non-solicitation and similar covenants that it has entered into prior to the date hereof or enter into after the date hereof (it being acknowledged and agreed that the automatic termination of any standstill provisions of any such agreement as the result of entering into an announcement of this Agreement will not be a violation of this Section 5.1(k)). Zazu will forthwith, if provided for in a confidentiality agreement with such person, request the return or destruction of all information provided to any third party that, has entered into a confidentiality agreement with Zazu to the extent that such information has not previously been returned or destroyed, and will use all commercially reasonable efforts to ensure that such requests are honoured.

(l)

Notwithstanding any of the provisions of this Section 5.1, the Zazu Board will have the right to respond, within the time and in the manner required by applicable Securities Laws, to any take-over bid or tender or exchange offer made for the Zazu Shares that it determines is not a Superior Proposal.

(m)

Zazu will ensure that its Representatives are aware of the provisions of this Section 5.1, and Zazu will be responsible for any breach of this Section 5.1 by any of its Representatives.

5.2 Expenses and Termination Fee

(a)

"Zazu Termination Fee Event" means any of the following events:

(i)

an Acquisition Proposal will have been made public or proposed publicly to Zazu or the Zazu Shareholders after the date hereof and prior to the Zazu Meeting, and

either Zazu or Solitario will have exercised its respective termination right under Section 6.1(b)(i) or Section 6.1(b)(ii), and

(B)

Zazu will have (x) completed any Acquisition Proposal within twelve months after this Agreement is terminated or (y) entered into an Acquisition Agreement in respect of any Acquisition Proposal or the Zazu Board will have recommended any Acquisition Proposal, in each case, within twelve months after this Agreement is terminated, which Acquisition Proposal in either case, as it may be modified or amended, is subsequently completed (whether before or after the expiry of such twelve-month period);

provided, however, that for the purposes of this Section 5.2(a)(i) all references to "20%" in the definition of Acquisition Proposal will be changed to "50%";

(ii)

this Agreement will have been terminated by Solitario pursuant to Section 6.1(c)(i) or Section 6.1(c)(ii); or

(iii)

this Agreement will have been terminated by Solitario pursuant to Section 6.1(c)(iii), Section 6.1(c)(vi) or Section 6.1(c)(vii) and Zazu will have (x) completed any Acquisition Proposal within twelve months after this Agreement is terminated or (y) entered into an Acquisition Agreement in respect of any Acquisition Proposal or the Zazu Board will have recommended any Acquisition Proposal, in each case, within twelve months after this Agreement is terminated, which Acquisition Proposal in either case, as it may be modified or amended, is subsequently completed (whether before or after the expiry of such twelve month period); and

(iv)

this Agreement will have been terminated by Zazu pursuant to Section 6.1(d)(i).

(b)

If a Zazu Termination Fee Event occurs, Zazu will pay to Solitario a termination fee of US$750,000 (the "Termination Fee") by wire transfer in immediately available funds to an account specified by Solitario. Zazu will pay the Termination Fee to Solitario on or prior to completion of the applicable Acquisition Proposal (in the case of a Zazu Termination Fee Event referred to in Section 5.2(a)(i) or 5.2(a)(iii), within one Business Day following termination of this Agreement (in the case of a Zazu Termination Fee Event referred to in Section 5.2(a)(ii)), or prior to or concurrent with termination of this Agreement (in the case of a Zazu Termination Fee Event referred to in Section 5.2(a)(iv)). If Zazu does not have sufficient financial resources to pay the Termination Fee, then it will be a condition of (i) any Superior Proposal referred to in Section 5.2(a)(ii) or Section 5.2(a)(iv), and (ii) any share or asset acquisition referred to in Section 5.2(a)(i)(B) or Section 5.2(a)(iii) where Zazu has entered into any agreement to support such share acquisition or to transfer such assets, as applicable, that the person making such Superior Proposal or acquisition, as applicable, will advance or otherwise provide to Zazu the cash required for Zazu to pay the Termination Fee, which amount will be so advanced or provided prior to the date on which Zazu is required to pay the Termination Fee. Solitario acknowledges that in no event will Zazu be obligated to pay more than one Termination Fee pursuant to this Section 5.2.

(c)

"Solitario Termination Fee Event" will occur if an Acquisition Proposal has been made public or proposed publicly to Solitario or the Solitario Shareholders after the date hereof and prior to the Solitario Meeting, and either Zazu or Solitario has exercised its termination rights under Section 6.1(b)(iv), provided, however, that for the purposes of this Section 5.2(c) all references to "Zazu" or "Zazu Shares" in the definition of Acquisition Proposal will be changed to "Solitario" and all references to "20%" in the definition of Acquisition Proposal will be changed to "50%".

(d)

If a Solitario Termination Fee Event occurs, Solitario will pay to Zazu US$750,000 by wire transfer in immediately available funds to an account specified by Zazu on or prior to termination of this Agreement.

(e)

Subject to Section 5.2(f), and except as otherwise specified herein, each Party will pay its respective legal and accounting costs, fees and expenses incurred in connection with the preparation, execution and delivery of this Agreement and all documents and instruments executed pursuant to this Agreement and any other costs, fees and expenses whatsoever and howsoever incurred, and will indemnify and save harmless the others from and against any claim for any broker's, finder's or placement fee or commission alleged to have been incurred as a result of any action by it in connection with the transactions hereunder.

(f)

Each Party acknowledges that all of the payment amounts set out in this Section 5.2 are payments in consideration for the disposition of Solitario's rights under this Agreement and represent liquidated damages which are a genuine pre-estimate of the damages which Solitario will suffer or incur as a result of the event giving rise to such payment and the resultant termination of this Agreement and are not penalties. Zazu irrevocably waives any right that it may have to raise as a defence that any such liquidated damages are excessive or punitive. For greater certainty, the Parties agree that the payment of an amount pursuant to this Section 5.2 in the manner provided herein is the sole and exclusive remedy of Solitario in respect of the event giving rise to such payment, provided, however, that nothing contained in this Section 5.2, and no payment of any such amount, will relieve or have the effect of relieving Zazu in any way from liability for damages incurred or suffered by Solitario as a result of an intentional or wilful breach of this Agreement, including the intentional or wilful making of a misrepresentation in this Agreement and nothing contained in this Section 5.2 will preclude Zazu from seeking injunctive relief in accordance with Section 8.13 to restrain the breach or threatened breach of the covenants or agreements set forth in this Agreement or the Confidentiality Agreement or otherwise to obtain specific performance of any of such acts, covenants or agreements, without the necessity of posting a bond or security in connection therewith.

Notwithstanding anything to the contrary contained in this Agreement, the Confidentiality Agreement will survive any termination hereof pursuant to Section 6.1.

6.3 Notice and Cure Provisions

If any Party determines at any time prior to the Effective Time that it intends to refuse to complete the transactions contemplated hereby because of any unfilled or unperformed condition contained in this Agreement, such Party will so notify the other Party forthwith upon making such determination in order that the other Party will have the right and opportunity to take such steps, at its own expense, as may be necessary for the purpose of fulfilling or performing such condition within a reasonable period of time, but in no event later than the Outside Date.

This Agreement may, at any time and from time to time before or after the holding of the Zazu Meeting but not later than the Effective Time, be amended by written agreement of the Parties without, subject to applicable Laws, further notice to or authorization on the part of the Zazu Shareholders, and any such amendment may, without limitation:

each Zazu Option, to the extent it has not been exercised as of the Effective Date, will be exchanged by the holder thereof, without any further act or formality and free and clear of all Liens, for a Replacement Option to purchase a number of Solitario Shares equal to the product of 0.3572 multiplied by the number of Zazu Shares issuable on exercise of such Zazu Option immediately prior to the Effective Time for an exercise price per Solitario Share equal to the exercise price per share of such Zazu Option immediately prior to the Effective Time divided by 0.3572 and rounded up to the nearest whole cent (provided that, if the foregoing calculation results in a Replacement Option being exercisable for a fraction of a Solitario Share, then the number of Solitario Shares subject to such Replacement Option will be rounded down to the next whole number of Solitario Shares) and the Zazu Options will thereupon be cancelled. The term of expiry, conditions to and manner of exercise and other terms and conditions of the Replacement Option will be the same as the terms and conditions of the Zazu Options for which it is exchanged except that such Replacement Option will be governed by the terms and conditions of the Solitario Incentive Plans and, in the event of any inconsistency or conflict the Solitario Incentive Plans will govern. Notwithstanding the foregoing, no such Replacement Option shall expire due to the holder ceasing to hold office or ceasing to be an employee or consultant and each such Replacement Option shall terminate on the earlier of (i) the date of expiry of the Zazu Option for which it was exchanged and (ii) the date 18 months after the Effective Date. Any document previously evidencing the Zazu Option will thereafter evidence and be deemed to evidence such Replacement Option and no certificates evidencing the Replacement Option will be issued;

If the adjustment to the Zazu Options contemplated by this paragraph results in a disposition of Zazu Options for options to acquire Solitario Shares or "new" Zazu Options, it is intended that the provisions of subsection 7(1.4) of the Tax Act apply to any such disposition. In the event that the Solitario Option In-The-Money Amount exceeds the Zazu Option In-The-Money Amount in respect of the Zazu Option exchanged in accordance with this Section 3.1(e), the number of Solitario Shares which may be acquired on exercise of the Zazu Option at and after the Effective Time will be adjusted accordingly with effect at and from the Effective Time to ensure that the Solitario Option In-The-Money Amount does not exceed the Zazu Option In- The-Money Amount;

(f)

each Zazu Optionholder and Zazu Shareholder, with respect to each step set out above applicable to such holder, will be deemed, at the time such step occurs, to have executed and delivered all consents, releases, assignments and waivers, statutory or otherwise, required to transfer such Zazu Option and Zazu Share, as the case may be, in accordance with such step; and

(g)

Zazu will file an election with the CRA to cease to be a public corporation for the purposes of the Tax Act.

3.2 Post Effective Time Procedures

(a)

Following the receipt of the Final Order and prior to the Effective Date, Solitario will deliver or arrange to be delivered to the Depositary the Consideration, including certificates representing the Solitario Shares required to be issued to Former Zazu Shareholders in accordance with the provisions of Section 3.1 hereof, which certificates will be held by the Depositary as agent and nominee for such Former Zazu Shareholders for distribution to such Former Zazu Shareholders in accordance with the provisions of Article 5 hereof.

(b)

Subject to the provisions of Article 5 hereof, and upon return of a properly completed Zazu Letter of Transmittal by a registered Former Zazu Shareholder together with certificates representing Zazu Shares and such other documents as the Depositary may require, Former Zazu Shareholders will be entitled to receive delivery of the certificates representing the Solitario Shares to which they are entitled pursuant to Section 3.1 hereof.

3.3 No Fractional Solitario Shares

In no event will any Zazu Shareholders be entitled to a fractional Solitario Share. Where the aggregate number of Solitario Shares to be issued to a Zazu Shareholder as consideration under or as a result of this Arrangement would result in a fraction of a Solitario Share being issuable, the number of Solitario Shares to be received by such securityholder will be rounded down to the nearest whole number of Solitario Shares and no former Zazu Shareholder will be entitled to any compensation in respect of a fractional Solitario Share.

3.4 U.S. Tax Matters

The Arrangement is intended to qualify as a reorganization within the meaning of Sections 368(a)(1)(B) of the Code and this Plan of Agreement and the Arrangement Agreement are intended to be a "plan of reorganization" within the meaning of the Treasury Regulations promulgated under Section 368 of the Code for purposes of Sections 354 and 361 of the Code.

Article 4
DISSENT RIGHTS

4.1 Rights of Dissent

Pursuant to the Interim Order, each registered Zazu Shareholder may exercise rights of dissent ("Dissent Rights") under Section 190 of the CBCA as modified by this Article 4 as the same may be modified by the Interim Order or the Final Order in respect of the Arrangement, provided that the written objection to the Arrangement Resolution contemplated by Section 190(5) of the CBCA must be sent to and received by Zazu not later than 5:00 p.m. (Eastern time) on the Business day immediately preceding the date of the Zazu Meeting or any date to which the Zazu

Meeting may be postponed or adjourned. Zazu Shareholders who duly exercise such rights of dissent and who:

(a)

are ultimately determined to be entitled to be paid fair value from Zazu, for the Dissenting Shares in respect of which they have exercised Dissent Rights, will be deemed to have irrevocably transferred such Dissenting Shares to Zazu pursuant to Section 3.1(a) in consideration of such fair value; or

(b)

are ultimately not entitled, for any reason, to be paid fair value for the Dissenting Shares in respect of which they have exercised Dissent Rights, will be deemed to have participated in the Arrangement on the same basis as a Zazu Shareholder who has not exercised Dissent Rights, as at and from the time specified in Section 3.1(a) and be entitled to receive only the consideration set forth in Section 3.1(c);

but in no case will Zazu or Solitario or any other person be required to recognize such holders as holders of Zazu Shares after the completion of the steps set forth in Section 3.1, and each Dissenting Zazu Shareholder will cease to be entitled to the rights of a Zazu Shareholder in respect of the Zazu Shares in relation to which such Dissenting Zazu Shareholder has exercised Dissent Rights and the central securities register of Zazu will be amended to reflect that such former holder is no longer the holder of such Zazu Shares as and from the completion of the steps in Section 3.1.

Article 5
CERTIFICATES

5.1 Payment of Consideration

(a)

As soon as practicable following the later of the Effective Date and the surrender to the Depositary for cancellation of a certificate that immediately prior to the Effective Time represented outstanding Zazu Shares that were transferred under Section 3.1, together with a duly completed Zazu Letter of Transmittal and such additional documents and instruments as the Depositary may reasonably require and such other documents and instruments as would have been required to effect such transfer under the CBCA and the articles of Zazu after giving effect to Section 3.1 the former holder of such Zazu Shares will be entitled to receive in exchange therefor, and the Depositary will deliver to such holder following the Effective Time, or, if requested by such former holder in the Zazu Letter of Transmittal, make available for pick up at its offices during normal business hours, the Consideration, comprised of a certificate representing the Solitario Shares that such holder is entitled to receive in accordance with Section 3.1 hereof, less any amounts withheld pursuant to Section 5.4.

(b)

Subject to Section 5.3, until surrendered as contemplated by this Section 5.1, each certificate which immediately prior to the Effective Time represented Zazu Shares will be deemed after the time described in Section 3.1 to represent only the right to receive from the Depositary upon such surrender the Consideration, comprised of a certificate representing the Solitario Shares, less any amounts withheld pursuant to Section 5.4.

(c)

Zazu and Solitario will cause the Depositary, as soon as a Former Zazu Shareholder becomes entitled to the Consideration in accordance with Section 3.1, to:

(i)

forward or cause to be forwarded by first class mail (postage paid) to such former holder at the address specified in the Zazu Letter of Transmittal;

(ii)

if requested by such former holder in the Zazu Letter of Transmittal make available at the offices of the Depositary specified in the Zazu Letter of Transmittal; or

(iii)

if the Zazu Letter of Transmittal neither specifies an address as described in Section 5.1(c)(i) nor contains a request as described in Section 5.1(c)(ii), forward or cause to be forwarded by first class mail (postage paid) to such former holder at the address of such former holder as shown on the applicable securities register maintained by or on behalf of Zazu immediately prior to the Effective Time;

a certificate representing the Solitario Shares issuable to such Former Zazu Shareholder in accordance with the provisions hereof.

(d)

No Zazu Shareholders or Zazu Optionholders will be entitled to receive any consideration or entitlement with respect to such Zazu Shares or Zazu Options other than any consideration or entitlement to which such holder is entitled to receive in accordance with Sections 3.1 and this Section 5.1 and the other terms of this Plan of Arrangement and, for greater certainty, no such holder with be entitled to receive any interest, dividends, premium or other payment in connection therewith, other than any declared but unpaid dividends.

5.2 Loss of Certificates

In the event any certificate which immediately prior to the Effective Time represented any outstanding Zazu Shares that were acquired by Solitario or Zazu pursuant to Section 3.1 has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the former holder of such Zazu Shares, the Depositary will deliver to such person or make available for pick up at its offices in exchange for such lost, stolen or destroyed certificate, the Consideration, comprised of a certificate representing the Solitario Shares which the former holder of such Zazu Shares is entitled to receive pursuant to Section 3.1 hereof in accordance with such holder's Zazu Letter of Transmittal. When authorizing such payment in relation to any lost, stolen or destroyed certificate, the former holder of such Zazu Shares will, as a condition precedent to the delivery of such Consideration, give a bond satisfactory to Zazu, Solitario and the Depositary in such sum as Solitario may direct or otherwise indemnify Zazu and Solitario in a manner satisfactory to Zazu and Solitario against any claim that may be made against Zazu or Solitario with respect to the certificate alleged to have been lost, stolen or destroyed.

5.3 Extinction of Rights

If any Former Zazu Shareholder fails to deliver to the Depositary the certificates, documents or instruments required to be delivered to the Depositary under Section 5.1 or Section 5.2 in order for such Former Zazu Shareholder to receive the Consideration which such former holder is entitled to receive pursuant to Section 3.1, on or before the sixth anniversary of the Effective Date, on the sixth anniversary of the Effective Date (i) such former holder will be deemed to have donated and forfeited to Solitario or its successor any Consideration held by the Depositary in trust for such former holder to which such former holder is entitled and (ii) any certificate representing Zazu Shares formerly held by such former holder will cease to represent a claim of any nature whatsoever and will be deemed to have been surrendered to Solitario and will be cancelled. Neither Zazu nor Solitario, or any of their respective successors, will be liable to any person in respect of any Consideration (including any consideration previously held by the Depositary in trust for any such former holder) which is forfeited to Zazu or Solitario or delivered to any public official pursuant to any applicable abandoned property, escheat or similar Law.

5.4 Withholding Rights

Subject to the provisions of any applicable income tax treaty between Canada and the country where the recipient is resident, Zazu, Solitario and the Depositary will be entitled to deduct and withhold from any consideration otherwise payable to any Zazu Shareholder or Zazu Optionholder under this Plan of Arrangement (including any payment to Dissenting Zazu Shareholders) such amounts as Zazu, Solitario or the Depositary may be required or permitted to deduct and withhold with respect to such payment or deliverable under the Tax Act, the Tax Code and the rules and regulations promulgated thereunder, or any provision of any provincial, state, local or foreign tax Law. For the purposes hereof, all such withheld amounts will be treated as having been paid to the person in respect of which such deduction and withholding was made on account of the obligation to make payment to such person hereunder, provided that such deducted or withheld amounts are actually remitted to the appropriate Governmental Authority by or on behalf of Zazu, Solitario or the Depositary, as the case may be. To the extent necessary, such deductions and withholdings may be effected by selling any Solitario Shares to which any such person may otherwise be entitled under this Plan of Arrangement, on such terms as Solitario reasonably determines, and any amount remaining following the sale, deduction and remittance will be paid to the person entitled thereto as soon as reasonably practicable.

5.5 No Liens

Any exchange or transfer of securities pursuant to this Plan of Arrangement will be free and clear of any Liens or other claims of third parties of any kind.

5.6 Paramountcy
