5.5 Pre-Acquisition Reorganization

(a)

▇▇▇▇▇▇ shall effect such reorganization of its business, operations, subsidiaries and assets or such other transactions (each, a “Pre-Acquisition Reorganization”) as HudBay may reasonably request prior to the Effective Date, and the Plan of Arrangement, if required, shall be modified accordingly; provided, however, that ▇▇▇▇▇▇ need not effect a Pre-Acquisition Reorganization which in the opinion of ▇▇▇▇▇▇, acting reasonably: (i) would require ▇▇▇▇▇▇ to obtain the prior approval of the ▇▇▇▇▇▇ Shareholders in respect of such Pre-Acquisition Reorganization other than at the ▇▇▇▇▇▇ Meeting; (ii) would impede or materially delay the consummation of the Arrangement; or (iii) would be inconsistent with Section 2.13 hereof. Without limiting the foregoing and other than as set forth in clause (i) above, ▇▇▇▇▇▇ shall use its best efforts to obtain all necessary consents, approvals or waivers from any persons to effect each Pre-Acquisition Reorganization, and ▇▇▇▇▇▇ shall cooperate with HudBay in structuring, planning and implementing any such Pre-Acquisition Reorganization. HudBay shall provide written notice to ▇▇▇▇▇▇ of any proposed Pre-Acquisition Reorganization at least ten (10) business days prior to the date of the ▇▇▇▇▇▇ Meeting. In addition:

(i)

HudBay shall indemnify and save harmless the officers, directors, employees, agents, advisors and representatives of ▇▇▇▇▇▇ and the ▇▇▇▇▇▇ Subsidiaries from and against any and all liabilities, Taxes, losses, damages, claims, costs, expenses, interest awards, judgments and penalties suffered or incurred by any of them in connection with or as a result of any Pre-Acquisition Reorganization;

(ii)

if the Plan of Arrangement is not completed, HudBay shall pay the implementation costs of the Pre-Acquisition Reorganization and any direct or indirect costs and liabilities thereof, including employment costs, Taxes

and liabilities as well as any costs, Taxes and liabilities that may be incurred to unwind any such Pre-Acquisition Reorganization (including actual out-of-pocket costs and expenses for Filing fees and external counsel).

(iii)

any Pre-Acquisition Reorganization or required cooperation of ▇▇▇▇▇▇ in structuring, planning and implementing any Pre-Acquisition Reorganization shall not become effective unless HudBay shall have waived or confirmed in writing the satisfaction of all conditions in its favour in Section 6.1 and Section 6.2 and shall have confirmed in writing that it is prepared to promptly without condition (other than the satisfaction of the condition contemplated by Section 6.2(a)) proceed to effect the Arrangement;

(iv)

any Pre-Acquisition Reorganization or required cooperation of ▇▇▇▇▇▇ in structuring, planning and implementing any Pre-Acquisition Reorganization shall not unreasonably interfere in material operations prior to the Effective Time of ▇▇▇▇▇▇ or any ▇▇▇▇▇▇ Subsidiary;

(v)

unless the Parties otherwise agree, any Pre-Acquisition Reorganization shall not require any filings with, notifications to or approvals of any Governmental Entity or third party (other than such Tax rulings, and filing such Tax elections or notifications and prefilings or pre-clearances with corporations branches or similar Governmental Entities, as are necessary or advisable in the circumstances);

(vi)

any Pre-Acquisition Reorganization shall not require ▇▇▇▇▇▇ or any ▇▇▇▇▇▇ Subsidiary to contravene any applicable Laws, their respective organizational documents or any Material Contract;

(vii)

▇▇▇▇▇▇ and the ▇▇▇▇▇▇ Subsidiaries shall 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 securityholder of ▇▇▇▇▇▇ 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; and

(viii)

such cooperation does not require the directors, officers, employees or agents of ▇▇▇▇▇▇ or the ▇▇▇▇▇▇ Subsidiaries to take any action in any capacity other than as a director, officer or employee.

(b)

HudBay acknowledges and agrees that the planning for and implementation of any Pre-Acquisition Reorganization shall not be considered a breach of any covenant under this Agreement and shall not be considered in determining whether a representation or warranty of ▇▇▇▇▇▇ hereunder has been breached. HudBay and ▇▇▇▇▇▇ shall work cooperatively and use reasonable commercial 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, ▇▇▇▇▇▇ shall not be liable for the failure of HudBay to benefit from any anticipated tax efficiency as a result of a Pre-Acquisition Reorganization.

5.6 Employment Agreements

Following the approval of the Arrangement Resolution, HudBay shall cause ▇▇▇▇▇▇ to honour such obligations, if any, under ▇▇▇▇▇▇’▇ employment agreements as are disclosed in Schedule 5.6 of the ▇▇▇▇▇▇ Disclosure Letter.

(a)

cause any of the representations or warranties of any Party contained herein to be untrue or inaccurate in any material respect on the date hereof or at the Effective Time (provided that this paragraph (a) shall not apply in the case of any event or state of facts resulting from actions or omissions of ▇▇▇▇▇▇ which are permitted or required by this Agreement); or

7.2 Non-Solicitation

7.2.1 Except as otherwise expressly provided in this Section 7.2, ▇▇▇▇▇▇ shall not, directly or indirectly, through any officer, director, employee, representative (including any financial or other advisor) or agent of ▇▇▇▇▇▇ or any of its subsidiaries (collectively, the “Representatives”): (a) solicit, initiate, knowingly encourage or facilitate (including by way of furnishing information or entering into any form of agreement, arrangement or understanding) any inquiries or proposals regarding an Acquisition Proposal; (b) engage in any discussions or negotiations with any person (other than HudBay or any of its affiliates) regarding an Acquisition Proposal, provided, however, that ▇▇▇▇▇▇ may advise any Person making an Acquisition Proposal that it does not constitute a Superior Proposal when the ▇▇▇▇▇▇ Board has so determined; (c) approve, accept, endorse or recommend, or propose publicly to accept, approve, endorse or recommend, any Acquisition Proposal; (d) accept or enter into or publicly propose to accept or enter into, any letter of intent, agreement in principle, agreement, understanding or arrangement in respect of an Acquisition Proposal; or (e) make a Change in Recommendation.

7.2.2 Except as otherwise provided in this Section 7.2, ▇▇▇▇▇▇ shall, and shall cause the ▇▇▇▇▇▇ Subsidiaries and the Representatives to immediately cease and cause to be terminated any solicitation, encouragement, discussion or negotiation with any persons conducted heretofore by ▇▇▇▇▇▇, any subsidiary of ▇▇▇▇▇▇ or any Representatives with respect to any Acquisition Proposal, and, in connection therewith, ▇▇▇▇▇▇ will discontinue access to any of its confidential information (and not establish or allow access to any of its confidential information, or any data room, virtual or otherwise) and shall as soon as possible request, to the extent that it is entitled to do so (and exercise all rights it has to require) the return or destruction of all confidential information regarding ▇▇▇▇▇▇ and its subsidiaries previously provided to any such person or any other person and will request (and exercise all rights it has to require) the destruction of all material including or incorporating or otherwise reflecting any material confidential information regarding ▇▇▇▇▇▇ and its subsidiaries. ▇▇▇▇▇▇ agrees that neither it nor any of its subsidiaries, shall terminate, waive, amend or modify any provision of any existing confidentiality agreement relating to an Acquisition Proposal or any standstill agreement to which it or any of its subsidiaries is a party (it being acknowledged and agreed that the automatic termination of any standstill provisions of any such agreement as the result of the entering into and announcement of this Agreement by ▇▇▇▇▇▇, pursuant to the express terms of any such agreement, shall not be a violation of this Section 7.2.2) and ▇▇▇▇▇▇ undertakes to enforce all standstill, non-disclosure, non-disturbance, non-solicitation and similar covenants that it or any of its subsidiaries have entered into prior to the date hereof, provided that ▇▇▇▇▇▇ shall not be prevented from considering any Superior Proposal if the provisions of this Section 7.2 are otherwise complied with.

7.2.3 Notwithstanding Sections 7.2.1 and 7.2.2 and any other provision of this Agreement or of any other agreement between the Parties or between ▇▇▇▇▇▇ and any other

person, including the provisions of any confidentiality or standstill agreement, if at any time following the date of this Agreement and prior to obtaining the approval of the Arrangement Resolution at the ▇▇▇▇▇▇ Meeting, ▇▇▇▇▇▇ receives a written Acquisition Proposal that the ▇▇▇▇▇▇ Board determines in good faith, after consultation with its financial advisors and outside counsel, constitutes or, if consummated in accordance with its terms, could reasonably be expected to result in a Superior Proposal, then ▇▇▇▇▇▇ may, provided it is in compliance with Section 7.2.4:

(a)

furnish information with respect to ▇▇▇▇▇▇ and its subsidiaries to the person making such Acquisition Proposal; and/or

(b)

enter into, participate, facilitate and maintain discussions or negotiations with, and otherwise cooperate with or assist, the person making such Acquisition Proposal,

provided that ▇▇▇▇▇▇ shall not, and shall not allow its Representatives to, disclose any non-public information with respect to ▇▇▇▇▇▇ to such person (i) if such non public information has not been previously provided to, or is not concurrently provided to, HudBay; and (ii) without entering into an agreement with such person substantially in the form of the Confidentiality Agreement containing terms that are no more favourable to such person than those found in the Confidentiality Agreement and that are not individually or in the aggregate materially more favourable to such person than those found in the Confidentiality Agreement. In particular but without limitation such agreement may not include any provision calling for an exclusive right to negotiate with ▇▇▇▇▇▇ and may not restrict ▇▇▇▇▇▇ or the ▇▇▇▇▇▇ Subsidiaries from complying with this Section 7.2.

7.2.4 ▇▇▇▇▇▇ shall promptly notify HudBay, at first orally and then in writing within 24 hours of receipt of the Acquisition Proposal, in the event it receives an Acquisition Proposal, or a request for non-public information, including the material terms and conditions thereof, and the identity of the person or persons making the Acquisition Proposal, and shall include copies of any such proposal, inquiry, offer or request, or any amendment to any of the foregoing. ▇▇▇▇▇▇ shall thereafter also provide such other details of such proposal, inquiry, offer or request, or any amendment to any of the foregoing, as HudBay may reasonably request. ▇▇▇▇▇▇ shall keep HudBay fully informed as to the status, including any changes to the material terms, of such proposal, inquiry, offer or request, or any amendment to any of the foregoing, and shall respond promptly to all inquiries from HudBay with respect thereto.

7.2.5 Notwithstanding anything in this Agreement to the contrary, but subject to Section 7.3, if at any time following the date of this Agreement and prior to obtaining the ▇▇▇▇▇▇ Shareholder Approval at the ▇▇▇▇▇▇ Meeting, ▇▇▇▇▇▇ receives an Acquisition Proposal which the ▇▇▇▇▇▇ Board concludes in good faith constitutes a Superior Proposal, the ▇▇▇▇▇▇ Board may enter into a definitive agreement with respect to such Superior Proposal.

7.2.6 Subject to Section 7.3, nothing contained in this Agreement shall prohibit the ▇▇▇▇▇▇ Board from taking any action or making a Change in Recommendation or from making any disclosure to any securityholders of ▇▇▇▇▇▇ prior to the Effective Time, if, in the good faith judgment of the ▇▇▇▇▇▇ Board, after consultation with outside legal counsel, failure to take such action or make such disclosure would be inconsistent with the ▇▇▇▇▇▇ Board’s exercise of its

fiduciary duties or such action or disclosure is otherwise required under applicable Law (including by responding to an Acquisition Proposal under a directors’ circular or otherwise as required under applicable Securities Laws); provided that, for greater certainty, in the event of a Change in Recommendation and a termination by HudBay of this Agreement pursuant to Section 8.2.1(c)(i) (but not including a termination by HudBay pursuant to Section 8.2.1(c)(i) in circumstances where the Change in Recommendation resulted from the occurrence of a Material Adverse Change with respect to HudBay), ▇▇▇▇▇▇ shall pay the Termination Fee as required by Section 7.5. In addition, subject to the provisions of this Section 7.2 and Section 7.3, nothing contained in this Agreement shall prevent ▇▇▇▇▇▇ or the ▇▇▇▇▇▇ Board from calling and holding a meeting of ▇▇▇▇▇▇ Shareholders, or any of them, requisitioned by ▇▇▇▇▇▇ Shareholders, or any of them, in accordance with the CBCA or ordered to be held by a court in accordance with applicable Laws.

7.3 Right to Match

▇▇▇▇▇▇ covenants that it will not accept, approve, endorse, recommend or enter into any agreement, understanding or arrangement in respect of an Acquisition Proposal (other than a confidentiality and standstill agreement permitted by Section 7.2.3) or make a Change in Recommendation in respect of an Acquisition Proposal unless:

(a)

▇▇▇▇▇▇ has complied with its obligations under Section 7.2 in all material respects and has provided HudBay with a copy of the Acquisition Proposal, pursuant to Section 7.2.4; and

(b)

a period (the “Response Period”) of five (5) business days has elapsed from the date that is the later of: (x) the date on which HudBay receives written notice from the ▇▇▇▇▇▇ Board that the ▇▇▇▇▇▇ Board has determined that the Acquisition Proposal constitutes a Superior Proposal, and to accept, approve, endorse, recommend or enter into a definitive agreement with respect to such Acquisition Proposal or to make a Change in Recommendation in respect of such Acquisition Proposal; and (y) the date HudBay receives a copy of the Acquisition Proposal.

7.3.2 During the Response Period, HudBay will have the right, but not the obligation, to offer to amend this Agreement and the Plan of Arrangement, including an increase in, or modification of, the aggregate Consideration. The ▇▇▇▇▇▇ Board shall review any such offer by HudBay to amend this Agreement and the Plan of Arrangement to determine whether the Acquisition Proposal to which HudBay is responding would continue to be a Superior Proposal when assessed against the Arrangement as it is proposed in writing by HudBay to be amended. If the ▇▇▇▇▇▇ Board determines that the Acquisition Proposal no longer constitutes a Superior Proposal, the ▇▇▇▇▇▇ Board will cause ▇▇▇▇▇▇ to enter into an amendment to this Agreement with HudBay incorporating the amendments to the Agreement and Plan of Arrangement as set out in the written offer to amend, and will promptly reaffirm its recommendation of the Arrangement and the prompt issuance of a press release to that effect. If the ▇▇▇▇▇▇ Board determines that the Acquisition Proposal continues to be a Superior Proposal, ▇▇▇▇▇▇ may approve and recommend that ▇▇▇▇▇▇ Shareholders accept such Superior Proposal and may make a Change in Recommendation in respect of the Superior Proposal or, subject to Section 7.3.4, terminate this Agreement pursuant to Section 8.2.1(d)(i) in order to accept or enter into an agreement, understanding or arrangement to proceed with the Superior Proposal.

7.3.3 Each successive amendment to any Acquisition Proposal that results in an increase in, or modification of, the Consideration (or value of such Consideration) to be received by the holders of the ▇▇▇▇▇▇ Shares shall constitute a new Acquisition Proposal for the purposes of this Section 7.3 and HudBay shall be afforded a new Response Period and the rights afforded in paragraph 7.3.2 in respect of each such Acquisition Proposal.

7.3.4 If prior to the expiry of the Response Period and during the Response Period, HudBay requests in writing that the ▇▇▇▇▇▇ Meeting proceed in compliance with Section 2.3 hereof, ▇▇▇▇▇▇ shall not be permitted to terminate the Agreement pursuant to Section 8.2.1(d)(i). Notwithstanding the foregoing, ▇▇▇▇▇▇ shall be permitted to accept or enter into an agreement, understanding or arrangement to proceed with a Superior Proposal provided that any such agreement, understanding or arrangement shall terminate if the Arrangement is approved at the ▇▇▇▇▇▇ Meeting and does not prevent the ▇▇▇▇▇▇ Meeting from proceeding in compliance with Section 2.3 hereof or impose any termination, expense reimbursement or other fees on ▇▇▇▇▇▇ or any of its Subsidiaries or result in the grant of any options or rights to acquire assets or securities of ▇▇▇▇▇▇ or any of its Subsidiaries, in each case that would be effective prior to the termination of this Agreement or survive the Effective Date.

7.3.5 Either ▇▇▇▇▇▇ or HudBay shall be entitled to adjourn or postpone the ▇▇▇▇▇▇ Meeting for a period of up to seven (7) business days from the date that ▇▇▇▇▇▇ has provided HudBay with a notice of an Acquisition Proposal under Section 7.3.1 if the Acquisition Proposal is received by ▇▇▇▇▇▇ less than seven (7) business days prior to the date of the ▇▇▇▇▇▇ Meeting provided, however, that the ▇▇▇▇▇▇ Meeting shall not be adjourned or postponed to a date later than the seventh (7) business day prior to the Outside Date.

7.4 HudBay Non-Solicitation

7.4.1 Except as otherwise expressly provided in this Section 7.4.1, HudBay shall not, directly or indirectly, through any officer, director, employee, representative (including any financial or other advisor) or agent of HudBay or any of its subsidiaries (collectively, the “HudBay Representatives”): (a) solicit, initiate, knowingly encourage or facilitate (including by way of furnishing information or entering into any form of agreement, arrangement or understanding) any inquiries or proposals regarding an Acquisition Proposal; (b) engage in any discussions or negotiations with any person regarding an Acquisition Proposal; (c) approve, accept, endorse or recommend, or propose publicly to accept, approve, endorse or recommend, any Acquisition Proposal; or (d) accept or enter into or publicly propose to accept or enter into, any letter of intent, agreement in principle, agreement, understanding or arrangement in respect of an Acquisition Proposal.

7.4.2 Except as otherwise provided in this Section 7.4, HudBay shall, and shall cause its subsidiaries and the HudBay Representatives to immediately cease and cause to be terminated any solicitation, encouragement, discussion or negotiation with any persons conducted heretofore by HudBay, any subsidiary of HudBay or any HudBay Representatives with respect to any Acquisition Proposal, and, in connection therewith, HudBay will discontinue access to any of its

confidential information (and not establish or allow access to any of its confidential information, or any data room, virtual or otherwise) and shall as soon as possible request, to the extent that it is entitled to do so (and exercise all rights it has to require) the return or destruction of all confidential information regarding HudBay and its subsidiaries previously provided to any such person or any other person and will request (and exercise all rights it has to require) the destruction of all material including or incorporating or otherwise reflecting any material confidential information regarding HudBay and its subsidiaries. HudBay agrees that neither it nor any of its subsidiaries, shall terminate, waive, amend or modify any provision of any existing confidentiality agreement relating to an Acquisition Proposal or any standstill agreement to which it or any of its subsidiaries is a party (it being acknowledged and agreed that the automatic termination of any standstill provisions of any such agreement as the result of the entering into and announcement of this Agreement by HudBay, pursuant to the express terms of any such agreement, shall not be a violation of this Section 7.4.2) and HudBay undertakes to enforce all standstill, non-disclosure, non-disturbance, non-solicitation and similar covenants that it or any of its subsidiaries have entered into prior to the date hereof.

7.4.3 Notwithstanding Sections 7.4.1 and 7.4.2 and any other provision of this Agreement or of any other agreement between the Parties or between HudBay and any other person, including the provisions of any confidentiality or standstill agreement, if at any time following the date of this Agreement and prior to the Effective Time, HudBay receives a Change of Control Proposal, then HudBay may, provided it is in compliance with Section 7.4.4:

(a)

furnish information with respect to HudBay and its subsidiaries to the person making such Change of Control Proposal; and/or

(b)

enter into, participate, facilitate and maintain discussions or negotiations with, and otherwise cooperate with or assist, the person making such Change of Control Proposal,

provided that HudBay shall not, and shall not allow the HudBay Representatives to, disclose any non-public information with respect to HudBay to such person (i) if such non-public information has not been previously provided to, or is not concurrently provided to, ▇▇▇▇▇▇; and (ii) if such person is not already party to a Confidentiality Agreement with HudBay, without entering into an agreement with such person substantially in the form of the Confidentiality Agreement containing terms that are no more favourable to such person than those found in the Confidentiality Agreement and that are not individually or in the aggregate materially more favourable to such person than those found in the Confidentiality Agreement. In particular but without limitation such agreement may not include any provision calling for an exclusive right to negotiate with HudBay and may not restrict HudBay or its subsidiaries from complying with this Section 7.4.3.

7.4.4 HudBay shall promptly notify ▇▇▇▇▇▇, at first orally and then in writing within 24 hours of receipt of the Acquisition Proposal, in the event it receives an Acquisition Proposal, or a request for non-public information, including the material terms and conditions thereof, and the identity of the person or persons making the Acquisition Proposal, and shall include copies of any such proposal, inquiry, offer or request, or any amendment to any of the foregoing. HudBay shall thereafter also provide such other details of such proposal, inquiry, offer or request, or any

amendment to any of the foregoing, as ▇▇▇▇▇▇ may reasonably request. HudBay shall keep ▇▇▇▇▇▇ fully informed as to the status, including any changes to the material terms, of such proposal, inquiry, offer or request, or any amendment to any of the foregoing, and shall respond promptly to all inquiries from ▇▇▇▇▇▇ with respect thereto.

7.4.5 Notwithstanding anything in this Agreement to the contrary, at any time following the date of this Agreement and prior to the Effective Time, the board of directors of HudBay may publicly accept or recommend that its shareholders accept and/or enter into a definitive agreement with respect to such Change of Control Proposal provided that:

(a)

if the Change of Control Proposal is structured as a take-over bid, the date upon which any securities may be taken up by the offeror shall be after the Effective Date, and

(b)

if the Change of Control Proposal requires approval by the HudBay Shareholders, the record date for any meeting of HudBay Shareholders that is required to be held to consider the Change of Control Proposal shall be after the Effective Date.

7.5 Expenses and Termination Fees

7.5.1 Except as otherwise provided herein, all fees, costs and expenses incurred in connection with this Agreement and the Plan of Arrangement shall be paid by the Party incurring such fees, costs or expenses.

7.5.2 If a Termination Fee Event occurs, ▇▇▇▇▇▇ shall pay HudBay (by wire transfer of immediately available funds) the Termination Fee in accordance with Section 7.5.5.

7.5.3 For the purposes of this Agreement, “Termination Fee” means $24,250,000.

7.5.4 For the purposes of this Agreement, “Termination Fee Event” means the termination of this Agreement:

(a)

by HudBay pursuant to Section 8.2.1(c)(i) (but not including a termination by HudBay pursuant to Section 8.2.1(c)(i) in circumstances where the Change in Recommendation resulted from the occurrence of a Material Adverse Change with respect to HudBay) or Section 8.2.1(c)(v), in either case prior to the ▇▇▇▇▇▇ Meeting;

(b)

by HudBay pursuant to Section 8.2.1(c)(iv);

(c)

by ▇▇▇▇▇▇ pursuant to Section 8.2.1(d)(i); or

(d)

by HudBay pursuant to Section 8.2.1(b)(i) or by either Party pursuant to 8.2.1(b)(iii), but only if, in the case of this paragraph (d), prior to the earlier of the termination of this Agreement or the holding of the ▇▇▇▇▇▇ Meeting, a bona fide Acquisition Proposal, or the intention to make an Acquisition Proposal, with respect to ▇▇▇▇▇▇ shall have been made to ▇▇▇▇▇▇ or publicly announced by any person (other than HudBay or any of its affiliates) and, within twelve months

following the date of such termination: (i) an Acquisition Proposal is consummated; or (ii) ▇▇▇▇▇▇ or one or more of its Subsidiaries enters into a definitive agreement in respect of an Acquisition Proposal or the ▇▇▇▇▇▇ Board approves or recommends such Acquisition Proposal which is subsequently consummated at any time thereafter, provided that for the purposes of this Section 7.5.4(d), all references to “20%” in the definition of “Acquisition Proposal” shall be deemed to be references to “50%”.

7.5.5 If a Termination Fee Event occurs due to a termination of this Agreement by ▇▇▇▇▇▇ pursuant to Section 8.2.1(d)(i), or by HudBay pursuant to Section 8.2.1(c)(i) or Section 8.2.1(c)(v), the Termination Fee shall be payable simultaneously with the occurrence of such Termination Fee Event. If a Termination Fee Event occurs due to a termination of this Agreement by HudBay pursuant to Section 8.2.1(c)(iv), the Termination Fee shall be payable within two (2) business days following such Termination Fee Event. If a Termination Fee Event occurs in the circumstances set out in Section 7.5.4(d), the Termination Fee shall be payable within two (2) business days following the closing of the applicable transaction referred to therein.

7.5.6 If ▇▇▇▇▇▇ terminates this Agreement pursuant to Section 8.2.1(d)(iv), HudBay shall pay ▇▇▇▇▇▇ (by wire transfer of immediately available funds) the Termination Fee within two (2) business days following such termination.

7.5.7 If ▇▇▇▇▇▇ terminates this Agreement pursuant to Section 8.2.1(d)(iii), HudBay shall pay ▇▇▇▇▇▇ $2,500,000 within two (2) business days following such termination.

7.5.8 If HudBay terminates this Agreement pursuant to Section 8.2.1(c)(iii), ▇▇▇▇▇▇ shall pay HudBay $2,500,000 within two (2) business days following such termination.

7.5.9 Each of the Parties acknowledges that the agreements contained in this Section 7.4 are an integral part of the transactions contemplated in this Agreement and that, without those agreements, the Parties would not enter into this Agreement. Each Party acknowledges that all of the payment amounts set out in this Section 7.4 are payments of liquidated damages which are a genuine pre-estimate of the damages, which the Party entitled to such damages 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. Each of ▇▇▇▇▇▇ and HudBay irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive. For greater certainty, each Party agrees that, upon any termination of this Agreement under circumstances where ▇▇▇▇▇▇ or HudBay is entitled to the Termination Fee and such Termination Fee is paid in full, ▇▇▇▇▇▇ or HudBay, as the case may be, shall be precluded from any other remedy against the other Party at law or in equity or otherwise (including, without limitation, an order for specific performance), and shall not seek to obtain any recovery, judgment, or damages of any kind, including consequential, indirect, or punitive damages, against the other Party or any of its subsidiaries or any of their respective directors, officers, employees, partners, managers, members, shareholders or affiliates in connection with this Agreement or the transactions contemplated hereby.

7.5.10 For the avoidance of doubt, in no event shall ▇▇▇▇▇▇ or HudBay be obligated to pay to the other Party an amount in respect of the termination of this Agreement that is, in aggregate, in excess of the Termination Fee.

7.5.11 Nothing in this Section 7.4 shall preclude a Party from seeking injunctive relief to restrain any 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 such covenants or agreements, without the necessity of posting bond or security in connection therewith.

7.6 Access to Information; Confidentiality

From the date hereof until the earlier of the Effective Time and the termination of this Agreement, subject to compliance with applicable Law and the terms of any existing Contracts, ▇▇▇▇▇▇ shall, and shall cause its subsidiaries and their respective officers, directors, employees, independent auditors, accounting advisers and agents to, afford to HudBay and to the officers, employees, agents and representatives of HudBay such access as HudBay may reasonably require at all reasonable times, including for the purpose of facilitating integration business planning, to their officers, employees, agents, properties, books, records and Contracts, and shall furnish HudBay with all data and information as HudBay may reasonably request. HudBay and ▇▇▇▇▇▇ acknowledge and agree that information furnished pursuant to this Section 7.6 shall be subject to the terms and conditions of the Confidentiality Agreement.

7.7 Insurance and Indemnification

7.7.1 HudBay will, or will cause ▇▇▇▇▇▇ and its subsidiaries to, maintain in effect without any reduction in scope or coverage for six (6) years from the Effective Date customary policies of directors’ and officers’ liability insurance providing protection no less favourable to the protection provided by the policies maintained by ▇▇▇▇▇▇ and its subsidiaries which are in effect immediately prior to the Effective Date and providing protection in respect of claims arising from facts or events which occurred on or prior to the Effective Date; provided, however, that HudBay acknowledges and agrees that prior to the Effective Date, ▇▇▇▇▇▇ may, in the alternative, purchase run off directors’ and officers’ liability insurance for a period of up to six (6) years from the Effective Date.

7.7.2 HudBay agrees that it shall directly honour all rights to indemnification or exculpation now existing in favour of present and former officers and directors of ▇▇▇▇▇▇ and its subsidiaries to the extent that they are disclosed in Schedule 7.7.2 of the ▇▇▇▇▇▇ Disclosure Letter, and acknowledges that such rights, to the extent that they are disclosed in Schedule 7.7.2 of the ▇▇▇▇▇▇ Disclosure Letter, shall survive the completion of the Plan of Arrangement and shall continue in full force and effect for a period of not less than six (6) years from the Effective Date.

7.7.3 The provisions of this Section 7.7 are intended for the benefit of, and shall be enforceable by, each insured or indemnified person, his or her heirs and his or her legal representatives and, for such purpose, ▇▇▇▇▇▇ hereby confirms that it is acting as agent and trustee on their behalf. Furthermore, this Section 7.7 shall survive the termination of this Agreement as a result of the occurrence of the Effective Date for a period of six (6) years.

9.3 Governing Law; Waiver of Jury Trial

This Agreement shall be governed, including as to validity, interpretation and effect, by the laws of the Province of Ontario and the laws of Canada applicable therein. Each of the Parties hereby irrevocably attorns to the exclusive jurisdiction of the Courts of the Province of Ontario in respect of all matters arising under and in relation to this Agreement and the Arrangement and waives any defences to the maintenance of an action in the Courts of the Province of Ontario. EACH PARTY TO THIS AGREEMENT HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF THE PARTIES IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT.

9.4 Injunctive Relief

Subject to Section 7.5, the Parties agree that irreparable harm would occur for which money damages would not be an adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions and other equitable relief to prevent breaches of this Agreement, any requirement for the securing or posting of any bond in connection with the obtaining of any such injunctive or other equitable relief hereby being waived.

9.5 Time of Essence

Time shall be of the essence in this Agreement.

9.6 Entire Agreement, Binding Effect and Assignment

This Agreement (including the exhibits and schedules hereto and the ▇▇▇▇▇▇ Disclosure Letter and the HudBay Disclosure Letter) and the Confidentiality Agreement constitute the entire agreement, and supersede all other prior agreements and understandings, both written and oral, between the Parties, or any of them, with respect to the subject matter hereof and thereof and, except as expressly provided herein, this Agreement is not intended to and shall not confer upon any person other than the Parties any rights or remedies hereunder. Neither this Agreement nor any of the rights, interests or obligations hereunder may be assigned by either of the Parties without the prior written consent of the other Parties.

9.7 Severability

If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

9.8 Counterparts, Execution

This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument. The Parties shall be entitled to rely upon delivery of an executed facsimile or similar executed electronic copy of this Agreement, and such facsimile or similar executed electronic copy shall be legally effective to create a valid and binding agreement between the Parties.

ARRANGEMENT

Section 3.01 Arrangement

At the Effective Time, except as otherwise noted herein, the following shall occur and shall be deemed to occur sequentially, in the following order, without any further act or formality, in each case, effective at the Effective Time:

(a)

each ▇▇▇▇▇▇ Share outstanding immediately prior to the Effective Time held by a Former ▇▇▇▇▇▇ Shareholder (other than a Dissenting Shareholder or HudBay or any subsidiary of HudBay) shall be transferred by the holder thereof to HudBay and, in consideration therefor, HudBay shall issue HudBay Shares on the basis of 0.3919 of a fully paid and non-assessable HudBay Share for each ▇▇▇▇▇▇ Common Share (the “Consideration”), subject to Sections 3.03, 3.04 and Article 5 hereof; and

(b)

contemporaneous with the transaction in paragraph (b) above, each ▇▇▇▇▇▇ Option outstanding immediately prior to the Effective Time, whether or not vested, shall be exchanged for an option (a “Converted HudBay Option”) to acquire (on the same terms and conditions as were applicable to such ▇▇▇▇▇▇ Option immediately before the Effective Time under the ▇▇▇▇▇▇ Stock Option Plan and the agreement evidencing the grant except to the extent that such Converted HudBay Option will expire on the expiry date for such option), the number (rounded down to the nearest whole number) of HudBay Shares equal to the product of: (A) the number of ▇▇▇▇▇▇ Shares subject to such ▇▇▇▇▇▇ Option

immediately prior to the Effective Time and (B) the ▇▇▇▇▇▇ Share Exchange Ratio. The exercise price per HudBay Share subject to any such converted HudBay Option shall be the amount (rounded up to the nearest one-hundredth of a cent) equal to the quotient of (A) the exercise price per ▇▇▇▇▇▇ Share subject to such ▇▇▇▇▇▇ Option immediately before the Effective Time divided by (B) the ▇▇▇▇▇▇ Share Exchange Ratio, provided that the exercise price otherwise determined shall be adjusted to the extent, if any, required to ensure that the Converted HudBay Option In-the-Money Amount immediately after the exchange is equal to (but in no event greater than) the ▇▇▇▇▇▇ Stock Option In-the-Money Amount of the exchanged ▇▇▇▇▇▇ Option immediately before the Effective Time.

Section 3.02 Post-Effective Time Procedures

(b)

Subject to the provisions of Article 5 hereof, and upon return of a properly completed letter of transmittal by a registered Former ▇▇▇▇▇▇ Shareholder together with certificates representing ▇▇▇▇▇▇ Shares and such other documents as the Depositary may require, Former ▇▇▇▇▇▇ Shareholders shall be entitled to receive delivery of the certificates representing the HudBay Shares and a cheque for the cash consideration to which they are entitled pursuant to Section 3.01(b) hereof.

Pursuant to the Interim Order, registered holders of ▇▇▇▇▇▇ Shares may exercise rights of dissent (“Dissent Rights”) under Section 190 of the CBCA, as modified by this Article 4, the Interim Order and the Final Order, with respect to ▇▇▇▇▇▇ Shares in connection with the Arrangement, provided that the written notice setting forth the objection of such registered ▇▇▇▇▇▇ Shareholders to the Arrangement and exercise of Dissent Rights must be received by ▇▇▇▇▇▇ not later than 5:00 p.m. on the business day that is two (2) business days before the ▇▇▇▇▇▇ Meeting or any date to which the ▇▇▇▇▇▇ Meeting may be postponed or adjourned and provided further that holders who exercise such rights of dissent and who:

(a)

are ultimately entitled to be paid fair value for their ▇▇▇▇▇▇ Shares, which fair value, notwithstanding anything to the contrary contained in Part XV of the CBCA, shall be determined as of the close of business on the day before the Effective Date, shall be deemed to have transferred their ▇▇▇▇▇▇ Shares to ▇▇▇▇▇▇ for cancellation immediately prior to the Effective Time, and ▇▇▇▇▇▇ shall fund such payment using its own assets; and

(b)

are ultimately not entitled, for any reason, to be paid fair value for their ▇▇▇▇▇▇ Shares shall be deemed to have participated in the Arrangement, as of the Effective Time, on the same basis as a non-dissenting holder of ▇▇▇▇▇▇ Shares and shall be entitled to receive only the consideration contemplated in Section 3.01(a) hereof that such holder would have received pursuant to the Arrangement if such holder had not exercised Dissent Rights.

ARTICLE FIVE

DELIVERY OF HUDBAY SHARES

Section 5.01 Delivery of HudBay Shares

(a)

Upon surrender to the Depositary for cancellation of a certificate that immediately before the Effective Time represented one or more outstanding ▇▇▇▇▇▇ Shares that were exchanged for HudBay Shares in accordance with Section 3.01 hereof, together with such other documents and instruments as would have been required to effect the transfer of the ▇▇▇▇▇▇ Shares formerly represented by such certificate under the CBCA and the articles of ▇▇▇▇▇▇ and such additional documents and instruments as the Depositary may reasonably require, the holder of such surrendered certificate shall be entitled to receive in exchange therefor, and the Depositary shall deliver to such holder following the Effective Time, a certificate representing the HudBay Shares that such holder is entitled to receive in accordance with Section 3.01 hereof.

(b)

After the Effective Time and until surrendered for cancellation as contemplated by Section 5.01(a) hereof, each certificate that immediately prior to the Effective

Time represented one or more ▇▇▇▇▇▇ Shares shall be deemed at all times to represent only the right to receive in exchange therefor a certificate representing HudBay Shares that the holder of such certificate is entitled to receive in accordance with Section 3.01 hereof.

Section 5.02 Lost Certificates

If any certificate, that immediately prior to the Effective Time represented one or more outstanding ▇▇▇▇▇▇ Shares that were exchanged for HudBay Shares in accordance with Section 3.01 hereof, shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the holder claiming such certificate to be lost, stolen or destroyed, the Depositary shall deliver in exchange for such lost, stolen or destroyed certificate, a certificate representing HudBay Shares that such holder is entitled to receive in accordance with Section 3.01 hereof. When authorizing such delivery of a certificate representing HudBay Shares that such holder is entitled to receive in exchange for such lost, stolen or destroyed certificate, the holder to whom a certificate representing such HudBay Shares is to be delivered shall, as a condition precedent to the delivery of such HudBay Shares, give a bond satisfactory to HudBay and the Depositary in such amount as HudBay and the Depositary may direct, or otherwise indemnify HudBay and the Depositary in a manner satisfactory to HudBay and the Depositary, against any claim that may be made against HudBay or the Depositary with respect to the certificate alleged to have been lost, stolen or destroyed and shall otherwise take such actions as may be required by the articles of ▇▇▇▇▇▇.

Section 5.03 Distributions with Respect to Unsurrendered Certificates

No dividend or other distribution declared or made after the Effective Time with respect to HudBay Shares with a record date after the Effective Time shall be delivered to the holder of any unsurrendered certificate that, immediately prior to the Effective Time, represented outstanding ▇▇▇▇▇▇ Shares unless and until the holder of such certificate shall have complied with the provisions of Section 5.01 or Section 5.02 hereof. Subject to applicable Law and to Section 5.04 hereof, at the time of such compliance, there shall, in addition to the delivery of a certificate representing HudBay Shares to which such holder is thereby entitled, be delivered to such holder, without interest, the amount of the dividend or other distribution with a record date after the Effective Time theretofore paid with respect to such HudBay Shares.

Section 5.04 Withholding Rights

HudBay and the Depositary shall be entitled to deduct and withhold from all dividends or other distributions otherwise payable to any Former ▇▇▇▇▇▇ Shareholder such amounts as HudBay or the Depositary is required or permitted to deduct and withhold with respect to such payment under the Tax Act, the United States Internal Revenue Code of 1986 or any provision of any applicable federal, provincial, state, local or foreign tax Law or treaty, in each case, as amended. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the Former ▇▇▇▇▇▇ Shareholder in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority.

Section 5.05 Limitation and Proscription

To the extent that a Former ▇▇▇▇▇▇ Shareholder shall not have complied with the provisions of Section 5.01 or Section 5.02 hereof on or before the date that is six (6) years after the Effective Date (the “final proscription date”), then the HudBay Shares that such Former ▇▇▇▇▇▇ Shareholder was entitled to receive shall be automatically cancelled without any repayment of capital in respect thereof and the certificates representing such HudBay Shares to which such Former ▇▇▇▇▇▇ Shareholder was entitled, shall be delivered to HudBay by the Depositary and the certificates shall be cancelled by HudBay, and the interest of the Former ▇▇▇▇▇▇ Shareholder in such HudBay Shares to which it was entitled shall be terminated as of such final proscription date.
