MATERIAL CHANGE REPORT

FORM 51-102F3

Item 1 Name and Address of Company

HudBay Minerals Inc.

Dundee Place

1 Adelaide Street East, Suite 2501

Toronto, Ontario

M5C 2V9

Item 2 Date of Material Change

January 9, 2011.

Item 3 News Release

A news release with respect to the material change referred to in this report was disseminated through Marketwire on January 10, 2011 and subsequently filed on SEDAR.

Item 4 Summary of Material Change

HudBay Minerals Inc. (“HudBay”) announced that it has entered into a support agreement (the “Support Agreement”) with Norsemont Mining Inc. (“Norsemont”), pursuant to which HudBay has agreed to offer to acquire by way of formal take-over bid (the “Offer”) all of the outstanding common shares of Norsemont (“Norsemont Shares”), including any Norsemont Shares issued prior to the expiration of the Offer upon the exercise, exchange or conversion of convertible securities of Norsemont, that HudBay does not already own.

Under the Offer, holders of Norsemont Shares who deposit their Norsemont Shares in accordance with the Offer will have the ability to elect to receive 0.2617 common shares of HudBay (“HudBay Shares”) and $0.001 in cash, $4.50 in cash, or a combination thereof (with the share consideration based on a price per HudBay Share of $17.19), subject to pro-ration necessary to effect maximum aggregate cash consideration of $130 million.

The board of directors of Norsemont, upon the recommendation of a Special Committee of the board and after consultation with its financial advisors, has determined that the consideration to be offered for the Norsemont Shares pursuant to the Offer is fair, from a financial point of view, to the holders of Norsemont Shares (other than HudBay and its affiliates), that it would be in the best interests of Norsemont to support and facilitate the Offer and enter into the Support Agreement and to recommend that the holders of Norsemont Shares tender their Norsemont Shares to the Offer.

Full details of the Offer will be included in HudBay’s take-over bid circular, which is expected to be mailed to holders of Norsemont Shares before the end of the month. The Offer will be open for acceptance until at least 5:00 p.m. (Toronto time) on the day that is 36 days from the date that the circular is mailed and will be subject to certain conditions (which may be waived by HudBay in its discretion), including there being deposited

under the Offer and not withdrawn at the expiry time of the Offer such number of Norsemont Shares that represent at least 50% (on a fully-diluted basis) plus one of the Norsemont Shares.

Item 5 Full Description of Material Change

On January 10, 2011, HudBay announced that it has entered into the Support Agreement, pursuant to which HudBay has agreed to offer to acquire all of the outstanding Norsemont Shares, including any Norsemont Shares issued prior to the expiration of the Offer upon the exercise, exchange or conversion of convertible securities of Norsemont, that HudBay does not already own.

Under the Offer, holders of Norsemont Shares who deposit their Norsemont Shares in accordance with the Offer will have the ability to elect, on an individual basis, to receive (a) 0.2617 HudBay Shares and $0.001 in cash, or (b) such amount of cash that is at least $0.001 and not greater than $4.50 and the number of HudBay Shares equal to (i) the excess of $4.50 over such elected cash amount, divided by (ii) $17.19, in each case subject to pro-ration to give effect to the maximum possible aggregate cash consideration to be paid for all Norsemont Shares on a fully-diluted basis, being no more than $130 million.

Pursuant to the Offer, holders of Norsemont Shares who tender their shares to the Offer and elect to receive the maximum equity consideration will receive consideration with a value of $4.65 per share, based on the volume weighted average trading price of $17.76 per HudBay Share on the Toronto Stock Exchange (the “TSX”) for the 20 trading days ended January 7, 2011, the last trading day prior to the announcement of the Offer. Such consideration represents a premium of 33%, based on the volume weighted average trading price of $3.49 per Norsemont Share on the TSX for the 20 trading days ended January 7, 2011.

Assuming HudBay acquires all of the Norsemont Shares pursuant to the Offer (and assuming holders of Norsemont Shares elect to receive the maximum equity consideration under the Offer) current holders of HudBay Shares will represent approximately 83% of the outstanding HudBay Shares and the former holders of Norsemont Shares will represent approximately 17% of the outstanding HudBay Shares.

The board of directors of Norsemont, upon the recommendation of a Special Committee of the board and after consultation with its financial advisors, has determined that the consideration to be offered for the Norsemont Shares pursuant to the Offer is fair, from a financial point of view, to the holders of Norsemont Shares (other than HudBay and its affiliates), that it would be in the best interests of Norsemont to support and facilitate the Offer and enter into the Support Agreement and to recommend that the holders of Norsemont Shares tender their Norsemont Shares to the Offer.

Cutfield Freeman & Co. Ltd. and Wellington West Capital Markets Inc. have provided opinions to the board of directors of Norsemont and the Special Committee of the board of directors of Norsemont that, as of January 9, 2011, the consideration to be received by the holders of Norsemont Shares under the Offer is fair, from a financial point of view, to the holders of Norsemont Shares (other than HudBay and its affiliates).

In addition, officers, directors and other shareholders of Norsemont holding approximately 34.4% of the Norsemont Shares, on a fully-diluted basis, have entered into lock-up agreements with HudBay under which they have agreed to tender their Norsemont Shares to the Offer. Together with HudBay’s 1.1% interest, these shares represent approximately 35.6% of the outstanding Norsemont Shares (on a fully-diluted basis).

The Support Agreement contains customary representations, warranties and covenants, including “non-solicitation” provisions that permit the board of directors of Norsemont to terminate the Support Agreement and enter into an agreement in respect of an unsolicited, superior proposal under certain circumstances, subject to, among other things, “matching rights” in favour of HudBay and payment of a termination payment of $21.6 million. A copy of the Support Agreement has been filed with the Canadian securities regulators and is available on SEDAR at www.sedar.com. Reference should be made to the Support Agreement for complete details of the terms and conditions contained therein.

Norsemont owns 100% of the Constancia copper project in southern Peru.

Full details of the Offer will be included in HudBay’s take-over bid circular, which is expected to be mailed to holders of Norsemont Shares before the end of the month. The Offer will be open for acceptance until at least 5:00 p.m. (Toronto time) on the day that is 36 days from the date that the circular is mailed and will be subject to certain conditions (which may be waived by HudBay in its discretion), including there being deposited under the Offer and not withdrawn at the expiry time of the Offer such number of Norsemont Shares that represent at least 50% (on a fully-diluted basis) plus one of the Norsemont Shares.

(a) The Offeror and the Company agree that, between the date hereof and the Take-Up Date, subject to the terms of the Company’s Stock Option Plan and the receipt of any necessary approvals and to Securities Laws, the Company may take such

- 19 -

actions as may be necessary or desirable, including amending the terms of any Options and the Company’s Stock Option Plan, to provide that all Options vest no later than immediately prior to the Take-Up Date and that each holder of vested Options shall be entitled to exercise such Options, in accordance with their terms, and thereby acquire Common Shares and, for that purpose, the Company may establish a facility pursuant to which holders of Options may borrow the funds necessary for the exercise of Options to permit all Common Shares issuable pursuant to such Options to be deposited under the Offer on terms that, among other things, result in the consideration received for such Common Shares being immediately applied to repay such borrowings.

(b) The Offeror and the Company agree that all Options tendered to the Company for exercise, surrender or cancellation, conditional upon the Offeror taking up the Common Shares under the Offer (a “Conditional Option Exercise”), shall be deemed to have been exercised or surrendered immediately prior to the take-up of the Common Shares by the Offeror. The Offeror shall accept as validly tendered under the Offer all of the Common Shares to be issued pursuant to the Conditional Option Exercise, provided that the holders of such Options confirm to the Company and the Offeror that such Common Shares are tendered pursuant to the Offer and provided that such holders have irrevocably agreed to surrender any of their remaining Options to the Company for cancellation effective on the Take-Up Date.

(c) The Company agrees that it will use commercially reasonable efforts to allow all outstanding Options to be either exercised, terminated, surrendered, cancelled or expire prior to the Take-Up Date, provided that, except as provided in Section 2.9(a) or Section 2.9(b), the Company shall not pay the holders any amount in consideration therefor without the prior approval of the Offeror, and the Company shall not grant any additional Options or other rights to purchase or acquire Common Shares, or make any amendments to outstanding Options without the prior written consent of the Offeror.

(d) The Company agrees to use reasonable commercial efforts to obtain as soon as practicable, and in any event prior to the Effective Time, the irrevocable agreement of all holders of Options that any Options that are not converted or exercised prior to the Take-Up Date shall either be surrendered or terminated or otherwise dealt with in a manner satisfactory to the Offeror prior to the Take-Up Date.

(e) The Offeror agrees to co-operate and make all such tendering or other arrangements with the Company to facilitate the exercise, conditional exercise, cancellation or surrender of Options and the deposit, pursuant to the Offer, of all Common Shares issued in connection therewith prior to the Expiry Time.

(f) The Company shall promptly notify the Offeror in writing of any exercise or surrender of Options pursuant to in Section 2.9(a) or Section 2.9(b). Such notice shall include full particulars of each such exercise or surrender.

- 20 -

(g) Notwithstanding any of the foregoing, the Company shall withhold and remit to the relevant Governmental Authority any amounts necessary in compliance with applicable Law and in connection therewith shall withhold such number of Common Shares issuable upon the exercise, conversion or exchange of any Convertible Securities, including Options, as may be necessary to satisfy the Company’s withholding obligations under applicable Law; and the Company shall use commercially reasonable efforts to take or cause to be taken all actions necessary to amend the Company’s Stock Option Plan in accordance with the foregoing.

(h) The Offeror acknowledges and agrees that the Offeror, the Company or any other Person or entity that makes a cash payment to a holder of Options in connection with the cancellation, surrender or termination of the Options as described herein will forego any deduction under the Tax Act with respect to such payment and will comply with the requirements described in subsection 110(1.1) of the Tax Act.

2.10 Change in Nature of Transaction

(a) On or prior to the Expiry Date, if the Offeror determines in its sole discretion that it is necessary or desirable to proceed with another form of transaction, including for greater certainty, a plan of arrangement, (an “Alternative Transaction”) whereby following completion of such Alternative Transaction, the Offeror or one or more of its Affiliates would own or control, directly or indirectly, 100% of the Common Shares on a Fully-Diluted Basis or substantially all of the assets of the Company and which provides the holders of Common Shares with a financial result at least equivalent to or better than the Offer, then, provided that such Alternative Transaction would not result in a delay or time to completion materially longer than the time permitted for the Contemplated Transactions and is otherwise not materially prejudicial to the Shareholders, the Company shall support the completion of such Alternative Transaction and take all actions necessary or desirable which are within its power to effect the completion of such Alternative Transaction, including, the holding of a meeting of holders of securities of the Company within 60 days of being notified of the Alternative Transaction and preparing and mailing any proxy circular of the Company in connection with such meeting.

(b) In the event of any proposed Alternative Transaction, the references in this Agreement to the Offer shall be deemed to be changed to “Alternative Transaction” with necessary modifications and all terms, covenants, representations and warranties of this Agreement (with the adjustments necessary to reflect the Alternative Transaction) shall be and shall be deemed to have been made in the context of the Alternative Transaction and, if requested by the Offeror, the Parties shall execute and deliver either an arrangement agreement in a customary form and consistent with the commercial terms of this Agreement or such other agreement giving effect to and evidencing such amendment as may be reasonably required as a result of such modification and adjustments.

The Company acknowledges that, promptly upon the take-up and payment by the Offeror pursuant to the Offer of such number of Common Shares which represent in excess of 50% of the then outstanding Common Shares plus one Common Share and from time to time thereafter, the Offeror shall be entitled to designate such number of directors of the Board of Directors, which would constitute a majority of the Board of Directors and the Company shall not frustrate the attempts of the Offeror to do so and covenants to co-operate with the Offeror, subject to applicable Law, to enable the designees of the Offeror to be elected or appointed to the Board of Directors, and to constitute a majority of the Board of Directors, including, without limitation, at the request of the Offeror, by using its best efforts to increase the size of the Board of Directors and reasonable commercial efforts to secure the resignations of such directors as the Offeror may request.

The Offeror and each of its subsidiaries is duly registered or otherwise authorized and qualified to do business and each is in good standing in each jurisdiction in which the character of its property and assets, owned, leased, licensed or otherwise held, or the nature of its activities makes such registration or authorization and qualification necessary except where the failure to be so registered, authorized or in good standing would not reasonably be expected to be material to the Offeror.

3.2 Capitalization

The authorized and issued capital of the Offeror consists of an unlimited number of Offeror Shares and an unlimited number of preference shares of which 149,431,339 Offeror Shares have been validly issued and are outstanding as fully paid and non-assessable shares as of January 4, 2011 and have not been issued in violation of any pre-emptive rights.

Except stock options and restricted share units of the Offeror issued or granted pursuant to incentive compensation plans of the Offeror, there are no options, warrants, conversion privileges, commitments (contingent or otherwise) or other Contract or any right or privilege

- 22 -

(whether by Law, pre-emptive or contractual) capable of becoming an agreement, for the purchase, allotment or issuance of, or subscription for, any securities of the Offeror, or any securities convertible or exchangeable into, or exercisable for, or otherwise evidencing a right to acquire, any securities of the Offeror. All securities of the Offeror (including the stock options and restricted share units) have been issued in compliance with all applicable corporate Laws and Securities Laws. Other than the Offeror Shares, stock options and restricted share units, there are no securities of the Offeror or of any of its subsidiaries outstanding which have the right to vote generally (or are convertible into or exchangeable for securities having the right to vote generally) with the shareholders of the Offeror on any matter. There are no outstanding Contracts or other obligations of the Offeror to (i) repurchase, redeem or otherwise acquire any of its securities or with respect to the voting or disposition of any of its outstanding securities, (ii) make any investment in or provide any funds to (whether in the form of a loan, capital contribution or otherwise) any Person in excess of $5 million in the aggregate, other than a wholly-owned subsidiary of the Offeror, or (iii) provide any guarantee with respect to any Person (other than a wholly-owned subsidiary of the Offeror).

All necessary corporate action has been taken by the Offeror to authorize the execution and delivery of this Agreement and the performance of its obligations hereunder and no other corporate proceedings on the part of the Offeror are necessary to authorize the execution and delivery by it of this Agreement or the performance of its obligations under this Agreement. Without limiting the generality of the foregoing, no approval of the shareholders of the Offeror is required for the Offeror to issue the Offeror Shares required to be issued pursuant to the Contemplated Transactions. This Agreement has been duly executed and delivered by the Offeror and constitutes a legal, valid and binding obligation of the Offeror enforceable against it in accordance with its terms, subject to the qualification that such enforceability may be limited by bankruptcy, insolvency, reorganization or other Laws of general application relating to or affecting rights of creditors and that equitable remedies, including specific performance, are discretionary and may not be ordered.

3.4 No Violations

None of the execution and delivery of this Agreement by the Offeror, and the performance by the Offeror of its obligations hereunder, will result in a material violation, contravention or default (or an event which, with notice or lapse of time or both, would constitute a default) under or require any consent, approval or notice under any of the terms and conditions of (A) the provisions of the constating documents of the Offeror, (B) any Law applicable to the Offeror or any of its subsidiaries or any of their property, or (C) any Contract to which the Offeror or any of its subsidiaries is a party or to which the Offeror, any of its subsidiaries or any of their respective property or assets, may be subject or by which the Offeror or any of its subsidiaries is bound except, in each case, for such violations, contraventions or defaults which would not, individually or in the aggregate, reasonably be expected to be material to the Offeror.

(i) solicit, assist, initiate, encourage or otherwise facilitate (including by way of furnishing information, permitting any visit to any facilities or properties of the Company or any of its subsidiaries or entering into any form of written or oral agreement, arrangement or understanding) any inquiries, offers or proposals regarding an Acquisition Proposal or otherwise co-operate in any way with, or assist with or participate in any way in any effort or attempt by any Person to make an Acquisition Proposal;

(v) accept, recommend, approve or enter into any letter of intent, agreement in principle, agreement, understanding or arrangement in respect of an Acquisition Proposal or providing for the payment of any break, termination or other fees or expenses to any Person in the event that the Company completes the transactions contemplated in this Agreement or any other transaction with the Offeror or any of its Affiliates agreed to prior to any termination of this Agreement, whether formal or informal.

- 47 -

(b) The Company shall, and shall cause its and its Representatives to, immediately terminate any existing discussions or negotiations with any Person (other than the Offeror or its Representatives) with respect to any Acquisition Proposal, whether or not initiated by the Company. The Company shall not amend, modify or waive any confidentiality agreement, standstill agreement or standstill provisions contained in any agreements entered into by the Company with other Parties relating to a potential Acquisition Proposal. Immediately upon execution of this Agreement, the Company shall request the return or destruction of all information provided to any third Parties who have entered into a confidentiality agreement with the Company (other than confidentiality agreements that by their terms have lapsed and were entered into prior to the convening of the Special Committee) relating to any potential Acquisition Proposal and shall use commercially reasonable efforts to ensure that such requests are honoured in accordance with the terms of such confidentiality agreements. The Company has provided the Offeror with a copy of the form of confidentiality agreement initially requested from any Person (if any) seeking access to the Company’s data room following the date on which the Special Committee was convened.

(c) The Company shall, as soon as practicable and in any event within 24 hours following receipt thereof notify the Offeror, at first orally and then as soon as possible thereafter in writing, of any inquiry, proposal or offer (or any amendment thereto) or request relating to or constituting an Acquisition Proposal, any request for discussions or negotiations, and/or any request for non-public information relating to the Company or for access to properties, books and records or a list of the Shareholders of the Company or other Company Securityholders of which the Company’s Representatives, are or become aware, or any amendments to the foregoing. Such notice shall include the material terms and conditions of, and the identity of the Person making, any inquiry, proposal or offer (including any amendment thereto), and shall include, in the case of a proposal or offer, copies of any such proposal or offer or any amendment to any of the foregoing. The Company shall keep the Offeror promptly and fully informed of the status, including any change to the material terms, of any such proposal or offer or any amendment to the foregoing, and will respond promptly to all reasonable inquiries by the Offeror with respect thereto.

(d) Notwithstanding Section 6.1(a) or any other provision of this Agreement to the contrary, if after the date of this Agreement, the Company receives a request for material non-public information in relation to a potential Acquisition Proposal or receives a bona fide Acquisition Proposal (that was not solicited, encouraged or facilitated after the date hereof in contravention of Section 6.1(a)), and (i) the Board of Directors determines in good faith consultation with its financial advisors and its legal counsel, that such Acquisition Proposal is, or could reasonably be expected to lead to, a Superior Proposal (notwithstanding that such Acquisition Proposal may be subject to a due diligence condition at such time), and (ii) the failure to provide the Person making such Acquisition Proposal with

- 48 -

access to such information regarding the Company would be inconsistent with the fiduciary duties of the Board of Directors, then, and only then, the Company may provide such Person with access to information regarding the Company, subject to the execution of a confidentiality agreement providing for standstill provisions (which shall not be waived or modified without the prior written approval of the Offeror) other than to effect a Superior Proposal, provided however that the Company sends a copy of any such confidentiality agreement to the Offeror promptly upon its execution and the Offeror is provided with a list of or copies of the information provided to such Person and is immediately provided with access to similar information to which such Person was provided.

(e) The Company shall ensure that its Representatives are aware of the provisions of this Section 6.1 and the Company shall be responsible for any breach of this Section 6.1 by such Representatives.

(i) the Board of Directors determines that the Acquisition Proposal constitutes a Superior Proposal;

(ii) the Company has complied with its obligations under all other provisions of this Article 6 and has provided the Offeror with a copy of the Acquisition Proposal (including, if applicable, a copy of any proposed agreement relating to such Acquisition Proposal);

(iii) a period (the “Response Period”) of five (5) Business Days shall have elapsed from the later of (A) the date on which the Offeror received written notice from the Board of Directors that the Board of Directors determined, subject only to compliance with this Section 6.2, to accept, approve, recommend or enter into a binding agreement to proceed with the Superior Proposal and (B) the date the Offeror received a copy of such Acquisition Proposal;

(iv) after the Response Period, the Board of Directors determines in good faith, after consultation with its financial advisors and outside counsel, that such Acquisition Proposal continues to constitute a Superior Proposal; and

(v) the Company concurrently terminates this Agreement pursuant to Section 8.1(g) and has paid or concurrently pays to the Offeror the Termination Payment pursuant to Section 6.3(a)(ii).

- 49 -

(b) During the Response Period, the Offeror will have the right, but not the obligation, to offer to amend in writing the terms of this Agreement and the Offer. The Company agrees that, if requested by the Offeror, it will negotiate with the Offeror in good faith to amend the terms of this Agreement and the Offer. The Board of Directors will review any such written amendment to determine, in good faith in the exercise of its fiduciary duties whether the Acquisition Proposal to which the Offeror is responding would be a Superior Proposal when assessed against the Offer as it is proposed by the Offeror to be amended. If the Board of Directors does not so determine, the Board of Directors will cause the Company to enter into an amendment to this Agreement reflecting the offer by the Offeror to amend the terms of the Offer and upon the execution by the Parties of such amendment will reaffirm its approval and recommendation in respect of the Offer, as so amended. If the Board of Directors does so determine, the Company may approve, recommend, accept or enter into an agreement, understanding or arrangement to proceed with the Superior Proposal.

(c) 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 Shareholders shall constitute a new Acquisition Proposal for the purposes of this Section 6.2 and the Offeror shall be afforded a new Response Period in respect of each such Acquisition Proposal.

6.3 Termination Payment and Expense Reimbursement

(a) The Offeror shall be entitled to a cash termination payment (the “Termination Payment”) in an amount equal to $21.6 million upon the occurrence of any of the following events (each a “Termination Payment Event”), which shall be paid by the Company, in immediately available funds, within the time specified in respect of any such Termination Payment Event to an account designated by the Offeror, as consideration for disposing of rights under this Agreement:

(i) the Offeror shall have terminated this Agreement pursuant to Section 8.1(c) (intentional breach or default by the Company) or Section 8.1(d) (change in or failure to make recommendation), in which case the Termination Payment shall be paid by 1:00 pm (Toronto time) on the third Business Day after this Agreement is terminated;

(ii) the Company proposes to terminate this Agreement pursuant to Section 8.1(g) (acceptance of Superior Proposal), in which case the Company shall pay the Offeror the Termination Payment prior to accepting, recommendation or approving or entering into of any definitive agreement relating to, a Superior Proposal; or

(iii) on or after the date hereof and prior to the Expiry Time, (A) an Acquisition Proposal is publicly announced or any Person has publicly announced an intention to make an Acquisition Proposal, and such Acquisition Proposal has not expired, been withdrawn or been publicly abandoned, (B) the Offer is not completed as a result of the Minimum

- 50 -

Tender Condition not having been met, (C) the Offeror terminates this Agreement, and (D) the Company enters into a definitive agreement providing for the completion of an Acquisition Proposal with the Person who made the Acquisition Proposal referred to in clause (A) above) and such Acquisition Proposal is completed within nine (9) months of such termination, in which case the Termination Payment shall be paid to the Offeror concurrently with the consummation of such Acquisition Proposal.

(b) If the Company does not have sufficient financial resources to pay the Termination Payment, in order for the Company to enter into any agreement (other than a confidentiality agreement permitted by Section 6.1(d)) relating to an Acquisition Proposal or Superior Proposal, where the entering into of such agreement or the acceptance, recommendation or approval of such Acquisition Proposal or Superior Proposal, as the case may be, (or the proposal by the Company to do so) would or may give rise to a Termination Payment Event, the Company shall not enter into any such agreement unless the Person making such Acquisition Proposal or Superior Proposal, as applicable, advances or otherwise provides to the Company the cash required for the Company to pay the Termination Payment, which amount shall be so advanced or provided prior to the date on which the Company is required to pay the Termination Payment pursuant to Section 6.3(a).

(c) Upon written notice to the Company, the Offeror may assign its right to receive the Termination Payment to any of its Affiliates.

(d) The Company acknowledges that the amount set out in Section 6.3(a) in respect of the Termination Payment represents liquidated damages which are a genuine pre-estimate of the damages, including opportunity costs, which the Offeror will suffer or incur as a result of the event giving rise to such damages and resultant termination of this Agreement, and is not a penalty and irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive.

(e) For greater certainty, the Company shall not be obligated to make more than one payment under this Section 6.3 if one or more of the events specified in Section 6.3(a) occurs.

6.4 Injunctive Relief

(a) Except as otherwise provided herein, any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by Law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy.

(b) The Parties hereby agree that irreparable damage would occur in the event that any provision of this Agreement were not performed in accordance with its

- 51 -

specific terms or were otherwise breached, and that money damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the Parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Company, on the one hand, or the Offeror, on the other hand, of any of their respective covenants or obligations set forth in this Agreement, the Company, on the one hand, and the Offeror, on the other hand, shall be entitled to an injunction or injunctions to prevent or restrain breaches or threatened breaches of this Agreement by the other, and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. Each of the Parties hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the other Party under this Agreement.

(c) The Parties hereto further agree that (x) by seeking the remedies provided for in this Section 6.4, a Party shall not in any respect waive its right to seek any other form of relief that may be available to a Party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 6.4 are not available or otherwise are not granted, and (y) nothing set forth in this Section 6.4 shall require any Party hereto to institute any proceeding for (or limit any Party’s right to institute any proceeding for) specific performance under this Section 6.4 prior or as a condition to exercising any termination right under Article 8 (and pursuing damages after such termination), nor shall the commencement of any legal proceeding restrict or limit any Party’s right to terminate this Agreement in accordance with the terms of Article 8 or pursue any other remedies under this Agreement that may be available then or thereafter.

6.5 Consents

The Company shall use its commercially reasonable efforts to obtain any consent from or to provide notice to any Person, in each case in form and substance acceptable to the Offeror, where consent is required or that has a right to receive notice in respect of this Agreement or the transaction contemplated hereunder.

GENERAL PROVISIONS

9.1 Officers’ and Directors’ Insurance

(a) The Offeror agrees that for the period from the Effective Time until six years after the Effective Time, the Offeror will cause the Company or any successor to the Company (including the successor resulting from the winding-up or liquidation or dissolution of the Company) to maintain the Company’s current directors’ and officers’ insurance policy or an equivalent policy, on a “trailing” or “run-off” basis, subject in either case to terms and conditions no less advantageous to the directors and officers of the Company than those contained in the policy in effect on the date hereof, for all present and former directors and officers of the Company, covering claims made prior to or within six years after the Effective Time; provided, however, that neither the Company nor the Offeror shall be required, in order to maintain such directors’ and officers’ insurance policy, to pay an annual premium in excess of 200% of the annual cost (the “Current Premia”) of the existing policies; and provided further that, if equivalent coverage cannot be obtained or can only be obtained by paying an annual premium in excess of 200% of the Current Premia, the Company and the Offeror shall only be required to obtain as much coverage as can be obtained by paying an annual premium equal to 200% of the Current Premia. Furthermore, prior to the Effective Time, the Company may, in the alternative, purchase pre-paid non-cancellable run off directors’ and officers’ liability insurance for a period of up to six years from the Effective Time providing such coverage for such Persons on terms comparable to those contained in the current insurance policies and at a cost that does not exceed $75,000 and in such event none of the Offeror, the Company or any of its subsidiaries will have any further obligation under this Section 9.1(a), except that from and after the Effective Time, the Company or the Offeror, as applicable, agrees not to take any action to terminate such directors’ and officers’ liability insurance.

- 60 -

(b) From and after the Effective Time, the Offeror shall, and shall cause the Company (or its successor) to, indemnify and hold harmless, to the fullest extent permitted under applicable Law, each present and former director, officer and employee of the Company (each, an “Indemnified Person”) against any costs or expenses (including reasonable legal fees), judgements, fines, losses, claims, damages or liabilities incurred in connection with any claim, inquiry, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or related to such Indemnified Person’s service as a director or officer of the Company, whether asserted or claimed prior to, at or after the Effective Time, including the approval of this Agreement, the completion of the Offer or any of the other Contemplated Transactions arising out of or related to this Agreement and the transactions contemplated hereby; provided that such Indemnified Person acted honestly and in good faith with a view to the best interests of the Company and, in the case of a criminal or administrative action or proceeding that is enforced by monetary penalty, the Indemnified Person had reasonable grounds for believing that his or her conduct was lawful. Neither the Offeror nor the Company shall settle, compromise or consent to the entry of any judgement in any claim, action, suit, proceeding or investigation or threatened claim, action, suit, proceeding or investigation involving or naming an Indemnified Person or arising out of or related to an Indemnified Person’s service as a director, officer or employee of the Company or services performed by such Persons at the request of the Company at or prior to or following the Effective Time without the prior written consent of that Indemnified Person (such consent not to be unreasonably withheld) unless such settlement, compromise or consent includes an unconditional release of such Indemnified Person from all liability arising out of such claim, action, suit, proceeding or investigation.

9.2 Certain Obligations

The Offeror acknowledges that the Company has obligations, among others, pursuant to the terms of the Notes, the Purchase Warrants and Options disclosed by the Company in writing to the Offeror prior to the date of this Agreement.

9.3 Notices

(a) Any notice, consent, waiver, direction or other communication required or permitted to be given under this Agreement by a Party shall be in writing and may be given by delivering same or sending same by facsimile transmission or by delivery addressed to the Party to which the notice is to be given at its address for service herein. Any notice, consent, waiver, direction or other communication aforesaid shall, if delivered, be deemed to have been given and received on the date on which it was delivered to the address provided herein (if a Business Day, if not, then the next succeeding Business Day, in the place of receipt) and if sent by facsimile transmission be deemed to have been given and received at the time of receipt (if a Business Day, if not, then the next succeeding Business Day) unless actually received after 5:00 p.m. (local time in the place of receipt) at the point of receipt in which case it shall be deemed to have been given and received on the next Business Day.

The failure by the Offeror at any time to exercise any of the foregoing rights will not be deemed a waiver of any such right and each such right will be deemed an ongoing right which may be asserted at any time and from time to time.

THIS LOCK-UP AGREEMENT (this “Agreement”) dated January 8, 2011 between HudBay Minerals Inc. (the “Offeror”), a corporation governed by the laws of Canada, and Robert William Baxter, an individual resident in the City of Lima, Peru (the “Seller”).

WHEREAS:

A. The Offeror is willing to make the Offer on the terms and subject to the conditions set out in the support agreement (as the same may be amended, modified or supplemented from time to time, the “Support Agreement”) with the Company;

B. The Seller is the registered and/or direct or indirect beneficial owner of, or exercises control or direction over, the issued and outstanding Common Shares and options, restricted share units and warrants to acquire Common Shares, as described more particularly in Appendix I hereto;

C. This Agreement sets out the terms and conditions of the Seller’s agreement to (i) support the Offer, (ii) exercise, convert or exchange all Convertible Securities (other than out-of-the money Convertible Securities) presently or subsequently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, (iii) deposit or cause to be deposited irrevocably under the Offer all Common Shares presently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, and all Common Shares subsequently legally or beneficially acquired by the Seller or over which the Seller will have control or direction, including Common Shares acquired upon exercise or exchange of Convertible Securities (collectively, the “Seller’s Securities”), and (iv) surrender for cancellation all out-of-the-money Convertible Securities;

D. The Offeror is relying on the covenants, representations and warranties of the Seller set forth in this Agreement in connection with the Offeror’s execution and delivery of the Support Agreement; and

E. Capitalized terms used herein but not otherwise defined herein have the meanings ascribed to such terms in the Support Agreement.

NOW THEREFORE in consideration of the Offeror agreeing to make the Offer, and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the Offeror and the Seller agree as follows:

ARTICLE 1

The Offeror will publicly announce its intention to make the Offer and make the Offer on the terms and subject to the conditions set out in the Support Agreement.

Provided all conditions to the Offer set out in Schedule A to the Support Agreement have been satisfied or waived prior to the Expiry Time, the Offeror will take up and pay for all the Common Shares deposited under the Offer as soon as reasonably possible and in any event not later than three (3) Business Days following the time at which it first becomes entitled to take up such securities under the Offer pursuant to applicable Laws. The obligation of the Offeror to take up and pay for the Common Shares under the Offer shall not be subject to any conditions except those conditions set out in Schedule A to the Support Agreement.

1.3 Conditions

The conditions to the making of the Offer are set out in Section 2.2 of the Support Agreement and the conditions of the Offer are set out in Schedule A to the Support Agreement.

ARTICLE 2

REPRESENTATIONS AND WARRANTIES

2.1 Representations and Warranties of the Seller

The Seller represents and warrants to and in favour of the Offeror as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and acknowledges that the Offeror is relying upon such representations and warranties in connection with the matters contemplated by this Agreement:

(a) Ownership, etc. The Seller is either (i) the legal and beneficial owner of, or (ii) the beneficial owner exercising control and direction over (but not the holder of record of) all of the Seller’s Securities. The only securities of the Company legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, are those listed on Appendix I to this Agreement. For greater certainty the term “Seller’s Securities” as used herein, includes the Common Shares and Convertible Securities listed on Appendix I and any securities of the Company into which they may be converted through the exercise, conversion or exchange of any Seller’s Securities. Except for the securities set out in Appendix I, the Seller has no agreement or option, or right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase or acquisition by the Seller or transfer to the Seller of additional securities of the Company (other than any agreements or amendments that the Seller may enter into to facilitate the exercise, cancellation or surrender of its Options, if any, as contemplated under the Support Agreement).

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

securityholders’ agreement, voting trust or other agreement affecting the Seller’s Securities or the ability of the Seller (or, after the acquisition by the Offeror pursuant to the Offer, the Offeror) to exercise all ownership rights thereto, including the voting of any such Seller’s Securities or any securities of the Company for which the Seller’s Securities may be exercised, converted or exchanged.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate, made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

- 3 -

(h) Existence and Authorization. If the Seller is not an individual, the Seller is validly existing under the laws of its jurisdiction of formation, continuance, incorporation or organization and has all necessary power, authority and capacity to enter into this Agreement and to carry out its obligations hereunder.

(i) Execution and Delivery. This Agreement has been duly executed and delivered by the Seller and constitutes a legal, valid and binding obligation of the Seller enforceable against it in accordance with its terms except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution.

2.2 Representations and Warranties of the Offeror

The Offeror represents and warrants as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and, where applicable, covenants to the Seller as follows and acknowledges that the Seller is relying upon these representations, warranties and covenants in connection with the entering into of this Agreement:

(a) the Offeror is validly existing under the laws of Canada and has the requisite power and authority to enter into this Agreement and to perform its obligations hereunder and under the Support Agreement;

(c) none of the execution and delivery by the Offeror of this Agreement, the Support Agreement or the performance of its obligations hereunder or thereunder will result in a breach of (i) the constating documents of the Offeror; (ii) any agreement or instrument to which the Offeror is a party or by which the Offeror or any of its property or assets is bound; (iii) any judgment, decree, order or award of any Governmental Authority applicable to the Offeror; or (iv) subject to receipt of the approval of the TSX and NYSE with respect to the listing of the Offeror Shares, any Law applicable to the Offeror; and

(d) the Offeror Shares to be issued pursuant to the Offer will, when issued pursuant to the Offer, be duly and validly issued as fully paid and non-assessable common shares in the capital of the Offeror; the Offeror has sufficient cash on-hand available to enable it to satisfy the aggregate cash consideration payable by the Offeror pursuant to the Offer.

(c) except to the extent that the Company provides notice in accordance with the Support Agreement, immediately notify the Offeror of any Acquisition Proposal of which the Seller or, to the knowledge of the Seller, any of its representatives or agents or, if applicable, its respective officers, directors, employees, directly or indirectly, becomes aware or any discussions or negotiations in respect thereof or request for non-public information relating to the Company or any of its Affiliates; such notification shall be made orally and in writing and shall include a description of the material terms and conditions together with a copy of all documentation relating to any such Acquisition Proposal or inquiry in respect of an Acquisition Proposal;

B. The Seller is the registered and/or direct or indirect beneficial owner of, or exercises control or direction over, the issued and outstanding Common Shares and options, restricted share units and warrants to acquire Common Shares, as described more particularly in Appendix I hereto;

C. This Agreement sets out the terms and conditions of the Seller’s agreement to (i) support the Offer, (ii) exercise, convert or exchange all Convertible Securities (other than out-of-the money Convertible Securities) presently or subsequently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, (iii) deposit or cause to be deposited irrevocably under the Offer all Common Shares presently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, and all Common Shares subsequently legally or beneficially acquired by the Seller or over which the Seller will have control or direction, including Common Shares acquired upon exercise or exchange of Convertible Securities (collectively, the “Seller’s Securities”), and (iv) surrender for cancellation all out-of-the-money Convertible Securities;

D. The Offeror is relying on the covenants, representations and warranties of the Seller set forth in this Agreement in connection with the Offeror’s execution and delivery of the Support Agreement; and

E. Capitalized terms used herein but not otherwise defined herein have the meanings ascribed to such terms in the Support Agreement.

NOW THEREFORE in consideration of the Offeror agreeing to make the Offer, and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the Offeror and the Seller agree as follows:

REPRESENTATIONS AND WARRANTIES

2.1 Representations and Warranties of the Seller

The Seller represents and warrants to and in favour of the Offeror as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and acknowledges that the Offeror is relying upon such representations and warranties in connection with the matters contemplated by this Agreement:

(a) Ownership, etc. The Seller is either (i) the legal and beneficial owner of, or (ii) the beneficial owner exercising control and direction over (but not the holder of record of) all of the Seller’s Securities. The only securities of the Company legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, are those listed on Appendix I to this Agreement. For greater certainty the term “Seller’s Securities” as used herein, includes the Common Shares and Convertible Securities listed on Appendix I and any securities of the Company into which they may be converted through the exercise, conversion or exchange of any Seller’s Securities. Except for the securities set out in Appendix I, the Seller has no agreement or option, or right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase or acquisition by the Seller or transfer to the Seller of additional securities of the Company (other than any agreements or amendments that the Seller may enter into to facilitate the exercise, cancellation or surrender of its Options, if any, as contemplated under the Support Agreement).

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

securityholders’ agreement, voting trust or other agreement affecting the Seller’s Securities or the ability of the Seller (or, after the acquisition by the Offeror pursuant to the Offer, the Offeror) to exercise all ownership rights thereto, including the voting of any such Seller’s Securities or any securities of the Company for which the Seller’s Securities may be exercised, converted or exchanged.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate, made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

- 3 -

(h) Existence and Authorization. If the Seller is not an individual, the Seller is validly existing under the laws of its jurisdiction of formation, continuance, incorporation or organization and has all necessary power, authority and capacity to enter into this Agreement and to carry out its obligations hereunder.

(i) Execution and Delivery. This Agreement has been duly executed and delivered by the Seller and constitutes a legal, valid and binding obligation of the Seller enforceable against it in accordance with its terms except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution.

2.2 Representations and Warranties of the Offeror

The Offeror represents and warrants as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and, where applicable, covenants to the Seller as follows and acknowledges that the Seller is relying upon these representations, warranties and covenants in connection with the entering into of this Agreement:

(c) none of the execution and delivery by the Offeror of this Agreement, the Support Agreement or the performance of its obligations hereunder or thereunder will result in a breach of (i) the constating documents of the Offeror; (ii) any agreement or instrument to which the Offeror is a party or by which the Offeror or any of its property or assets is bound; (iii) any judgment, decree, order or award of any Governmental Authority applicable to the Offeror; or (iv) subject to receipt of the approval of the TSX and NYSE with respect to the listing of the Offeror Shares, any Law applicable to the Offeror; and

(d) the Offeror Shares to be issued pursuant to the Offer will, when issued pursuant to the Offer, be duly and validly issued as fully paid and non-assessable common shares in the capital of the Offeror; the Offeror has sufficient cash on-hand available to enable it to satisfy the aggregate cash consideration payable by the Offeror pursuant to the Offer.

LOCK UP AGREEMENT

THIS LOCK-UP AGREEMENT (this “Agreement”) dated January 8, 2011 between HudBay Minerals Inc. (the “Offeror”), a corporation governed by the laws of Canada, and Gaston Augusto Loyola Puma, an individual resident in the City of Arequipa, Peru (the “Seller”).

WHEREAS:

A. The Offeror is willing to make the Offer on the terms and subject to the conditions set out in the support agreement (as the same may be amended, modified or supplemented from time to time, the “Support Agreement”) with the Company;

B. The Seller is the registered and/or direct or indirect beneficial owner of, or exercises control or direction over, the issued and outstanding Common Shares and options, restricted share units and warrants to acquire Common Shares, as described more particularly in Appendix I hereto;

C. This Agreement sets out the terms and conditions of the Seller’s agreement to (i) support the Offer, (ii) exercise, convert or exchange all Convertible Securities (other than out-of-the money Convertible Securities) presently or subsequently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, (iii) deposit or cause to be deposited irrevocably under the Offer all Common Shares presently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, and all Common Shares subsequently legally or beneficially acquired by the Seller or over which the Seller will have control or direction, including Common Shares acquired upon exercise or exchange of Convertible Securities (collectively, the “Seller’s Securities”), and (iv) surrender for cancellation all out-of-the-money Convertible Securities;

D. The Offeror is relying on the covenants, representations and warranties of the Seller set forth in this Agreement in connection with the Offeror’s execution and delivery of the Support Agreement; and

E. Capitalized terms used herein but not otherwise defined herein have the meanings ascribed to such terms in the Support Agreement.

NOW THEREFORE in consideration of the Offeror agreeing to make the Offer, and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the Offeror and the Seller agree as follows:

ARTICLE 1

OFFER

1.1 Offer for Common Shares

The Offeror will publicly announce its intention to make the Offer and make the Offer on the terms and subject to the conditions set out in the Support Agreement.

1.2 Take-Up and Payment

Provided all conditions to the Offer set out in Schedule A to the Support Agreement have been satisfied or waived prior to the Expiry Time, the Offeror will take up and pay for all the Common Shares deposited under the Offer as soon as reasonably possible and in any event not later than three (3) Business Days following the time at which it first becomes entitled to take up such securities under the Offer pursuant to applicable Laws. The obligation of the Offeror to take up and pay for the Common Shares under the Offer shall not be subject to any conditions except those conditions set out in Schedule A to the Support Agreement.

1.3 Conditions

The conditions to the making of the Offer are set out in Section 2.2 of the Support Agreement and the conditions of the Offer are set out in Schedule A to the Support Agreement.

ARTICLE 2

REPRESENTATIONS AND WARRANTIES

2.1 Representations and Warranties of the Seller

The Seller represents and warrants to and in favour of the Offeror as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and acknowledges that the Offeror is relying upon such representations and warranties in connection with the matters contemplated by this Agreement:

(a) Ownership, etc. The Seller is either (i) the legal and beneficial owner of, or (ii) the beneficial owner exercising control and direction over (but not the holder of record of) all of the Seller’s Securities. The only securities of the Company legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, are those listed on Appendix I to this Agreement. For greater certainty the term “Seller’s Securities” as used herein, includes the Common Shares and Convertible Securities listed on Appendix I and any securities of the Company into which they may be converted through the exercise, conversion or exchange of any Seller’s Securities. Except for the securities set out in Appendix I, the Seller has no agreement or option, or right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase or acquisition by the Seller or transfer to the Seller of additional securities of the Company (other than any agreements or amendments that the Seller may enter into to facilitate the exercise, cancellation or surrender of its Options, if any, as contemplated under the Support Agreement).

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

securityholders’ agreement, voting trust or other agreement affecting the Seller’s Securities or the ability of the Seller (or, after the acquisition by the Offeror pursuant to the Offer, the Offeror) to exercise all ownership rights thereto, including the voting of any such Seller’s Securities or any securities of the Company for which the Seller’s Securities may be exercised, converted or exchanged.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate, made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

- 3 -

(h) Existence and Authorization. If the Seller is not an individual, the Seller is validly existing under the laws of its jurisdiction of formation, continuance, incorporation or organization and has all necessary power, authority and capacity to enter into this Agreement and to carry out its obligations hereunder.

(i) Execution and Delivery. This Agreement has been duly executed and delivered by the Seller and constitutes a legal, valid and binding obligation of the Seller enforceable against it in accordance with its terms except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution.

2.2 Representations and Warranties of the Offeror

The Offeror represents and warrants as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and, where applicable, covenants to the Seller as follows and acknowledges that the Seller is relying upon these representations, warranties and covenants in connection with the entering into of this Agreement:

(a) the Offeror is validly existing under the laws of Canada and has the requisite power and authority to enter into this Agreement and to perform its obligations hereunder and under the Support Agreement;

(b) this Agreement has been duly executed and delivered by the Offeror and constitutes a legal, valid and binding obligation, enforceable by the Seller against the Offeror in accordance with its terms, except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution;

(c) none of the execution and delivery by the Offeror of this Agreement, the Support Agreement or the performance of its obligations hereunder or thereunder will result in a breach of (i) the constating documents of the Offeror; (ii) any agreement or instrument to which the Offeror is a party or by which the Offeror or any of its property or assets is bound; (iii) any judgment, decree, order or award of any Governmental Authority applicable to the Offeror; or (iv) subject to receipt of the approval of the TSX and NYSE with respect to the listing of the Offeror Shares, any Law applicable to the Offeror; and

(d) the Offeror Shares to be issued pursuant to the Offer will, when issued pursuant to the Offer, be duly and validly issued as fully paid and non-assessable common shares in the capital of the Offeror; the Offeror has sufficient cash on-hand available to enable it to satisfy the aggregate cash consideration payable by the Offeror pursuant to the Offer.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate, made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

B. The Seller is the registered and/or direct or indirect beneficial owner of, or exercises control or direction over, the issued and outstanding Common Shares and options, restricted share units and warrants to acquire Common Shares, as described more particularly in Appendix I hereto;

C. This Agreement sets out the terms and conditions of the Seller’s agreement to (i) support the Offer, (ii) exercise, convert or exchange all Convertible Securities (other than out-of-the money Convertible Securities) presently or subsequently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, (iii) deposit or cause to be deposited irrevocably under the Offer all Common Shares presently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, and all Common Shares subsequently legally or beneficially acquired by the Seller or over which the Seller will have control or direction, including Common Shares acquired upon exercise or exchange of Convertible Securities (collectively, the “Seller’s Securities”), and (iv) surrender for cancellation all out-of-the-money Convertible Securities;

D. The Offeror is relying on the covenants, representations and warranties of the Seller set forth in this Agreement in connection with the Offeror’s execution and delivery of the Support Agreement; and

E. Capitalized terms used herein but not otherwise defined herein have the meanings ascribed to such terms in the Support Agreement.

NOW THEREFORE in consideration of the Offeror agreeing to make the Offer, and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the Offeror and the Seller agree as follows:

REPRESENTATIONS AND WARRANTIES

2.1 Representations and Warranties of the Seller

The Seller represents and warrants to and in favour of the Offeror as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and acknowledges that the Offeror is relying upon such representations and warranties in connection with the matters contemplated by this Agreement:

(a) Ownership, etc. The Seller is either (i) the legal and beneficial owner of, or (ii) the beneficial owner exercising control and direction over (but not the holder of record of) all of the Seller’s Securities. The only securities of the Company legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, are those listed on Appendix I to this Agreement. For greater certainty the term “Seller’s Securities” as used herein, includes the Common Shares and Convertible Securities listed on Appendix I and any securities of the Company into which they may be converted through the exercise, conversion or exchange of any Seller’s Securities. Except for the securities set out in Appendix I, the Seller has no agreement or option, or right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase or acquisition by the Seller or transfer to the Seller of additional securities of the Company (other than any agreements or amendments that the Seller may enter into to facilitate the exercise, cancellation or surrender of its Options, if any, as contemplated under the Support Agreement).

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

securityholders’ agreement, voting trust or other agreement affecting the Seller’s Securities or the ability of the Seller (or, after the acquisition by the Offeror pursuant to the Offer, the Offeror) to exercise all ownership rights thereto, including the voting of any such Seller’s Securities or any securities of the Company for which the Seller’s Securities may be exercised, converted or exchanged.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate, made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

- 3 -

(h) Existence and Authorization. If the Seller is not an individual, the Seller is validly existing under the laws of its jurisdiction of formation, continuance, incorporation or organization and has all necessary power, authority and capacity to enter into this Agreement and to carry out its obligations hereunder.

(i) Execution and Delivery. This Agreement has been duly executed and delivered by the Seller and constitutes a legal, valid and binding obligation of the Seller enforceable against it in accordance with its terms except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution.

2.2 Representations and Warranties of the Offeror

(c) none of the execution and delivery by the Offeror of this Agreement, the Support Agreement or the performance of its obligations hereunder or thereunder will result in a breach of (i) the constating documents of the Offeror; (ii) any agreement or instrument to which the Offeror is a party or by which the Offeror or any of its property or assets is bound; (iii) any judgment, decree, order or award of any Governmental Authority applicable to the Offeror; or (iv) subject to receipt of the approval of the TSX and NYSE with respect to the listing of the Offeror Shares, any Law applicable to the Offeror; and

B. The Seller is the registered and/or direct or indirect beneficial owner of, or exercises control or direction over, the issued and outstanding Common Shares and options, restricted share units and warrants to acquire Common Shares, as described more particularly in Appendix I hereto;

C. This Agreement sets out the terms and conditions of the Seller’s agreement to (i) support the Offer, (ii) exercise, convert or exchange all Convertible Securities (other than out-of-the money Convertible Securities) presently or subsequently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, (iii) deposit or cause to be deposited irrevocably under the Offer all Common Shares presently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, and all Common Shares subsequently legally or beneficially acquired by the Seller or over which the Seller will have control or direction, including Common Shares acquired upon exercise or exchange of Convertible Securities (collectively, the “Seller’s Securities”), and (iv) surrender for cancellation all out-of-the-money Convertible Securities;

D. The Offeror is relying on the covenants, representations and warranties of the Seller set forth in this Agreement in connection with the Offeror’s execution and delivery of the Support Agreement; and

E. Capitalized terms used herein but not otherwise defined herein have the meanings ascribed to such terms in the Support Agreement.

NOW THEREFORE in consideration of the Offeror agreeing to make the Offer, and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the Offeror and the Seller agree as follows:

REPRESENTATIONS AND WARRANTIES

2.1 Representations and Warranties of the Seller

The Seller represents and warrants to and in favour of the Offeror as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and acknowledges that the Offeror is relying upon such representations and warranties in connection with the matters contemplated by this Agreement:

(a) Ownership, etc. The Seller is either (i) the legal and beneficial owner of, or (ii) the beneficial owner exercising control and direction over (but not the holder of record of) all of the Seller’s Securities. The only securities of the Company legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, are those listed on Appendix I to this Agreement. For greater certainty the term “Seller’s Securities” as used herein, includes the Common Shares and Convertible Securities listed on Appendix I and any securities of the Company into which they may be converted through the exercise, conversion or exchange of any Seller’s Securities. Except for the securities set out in Appendix I, the Seller has no agreement or option, or right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase or acquisition by the Seller or transfer to the Seller of additional securities of the Company (other than any agreements or amendments that the Seller may enter into to facilitate the exercise, cancellation or surrender of its Options, if any, as contemplated under the Support Agreement).

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

securityholders’ agreement, voting trust or other agreement affecting the Seller’s Securities or the ability of the Seller (or, after the acquisition by the Offeror pursuant to the Offer, the Offeror) to exercise all ownership rights thereto, including the voting of any such Seller’s Securities or any securities of the Company for which the Seller’s Securities may be exercised, converted or exchanged.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate, made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

- 3 -

(h) Existence and Authorization. If the Seller is not an individual, the Seller is validly existing under the laws of its jurisdiction of formation, continuance, incorporation or organization and has all necessary power, authority and capacity to enter into this Agreement and to carry out its obligations hereunder.

(i) Execution and Delivery. This Agreement has been duly executed and delivered by the Seller and constitutes a legal, valid and binding obligation of the Seller enforceable against it in accordance with its terms except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution.

(c) none of the execution and delivery by the Offeror of this Agreement, the Support Agreement or the performance of its obligations hereunder or thereunder will result in a breach of (i) the constating documents of the Offeror; (ii) any agreement or instrument to which the Offeror is a party or by which the Offeror or any of its property or assets is bound; (iii) any judgment, decree, order or award of any Governmental Authority applicable to the Offeror; or (iv) subject to receipt of the approval of the TSX and NYSE with respect to the listing of the Offeror Shares, any Law applicable to the Offeror; and

(d) the Offeror Shares to be issued pursuant to the Offer will, when issued pursuant to the Offer, be duly and validly issued as fully paid and non-assessable common shares in the capital of the Offeror; the Offeror has sufficient cash on-hand available to enable it to satisfy the aggregate cash consideration payable by the Offeror pursuant to the Offer.

THIS LOCK-UP AGREEMENT (this “Agreement”) dated January 9, 2011 between HudBay Minerals Inc. (the “Offeror”), a corporation governed by the laws of Canada, and Brian Kerzner, an individual resident in the City of Vancouver (the “Seller”).

WHEREAS:

A. The Offeror is willing to make the Offer on the terms and subject to the conditions set out in the support agreement (as the same may be amended, modified or supplemented from time to time, the “Support Agreement”) with the Company;

B. The Seller is the registered and/or direct or indirect beneficial owner of, or exercises control or direction over, the issued and outstanding Common Shares and options, restricted share units and warrants to acquire Common Shares, as described more particularly in Appendix I hereto;

C. This Agreement sets out the terms and conditions of the Seller’s agreement to (i) support the Offer, (ii) exercise, convert or exchange all Convertible Securities (other than out-of-the money Convertible Securities) presently or subsequently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, (iii) deposit or cause to be deposited irrevocably under the Offer all Common Shares presently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, and all Common Shares subsequently legally or beneficially acquired by the Seller or over which the Seller will have control or direction, including Common Shares acquired upon exercise or exchange of Convertible Securities (collectively, the “Seller’s Securities”), and (iv) surrender for cancellation all out-of-the-money Convertible Securities;

D. The Offeror is relying on the covenants, representations and warranties of the Seller set forth in this Agreement in connection with the Offeror’s execution and delivery of the Support Agreement; and

E. Capitalized terms used herein but not otherwise defined herein have the meanings ascribed to such terms in the Support Agreement.

NOW THEREFORE in consideration of the Offeror agreeing to make the Offer, and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the Offeror and the Seller agree as follows:

ARTICLE 1

OFFER

1.1 Offer for Common Shares

The Offeror will publicly announce its intention to make the Offer and make the Offer on the terms and subject to the conditions set out in the Support Agreement.

1.2 Take-Up and Payment

Provided all conditions to the Offer set out in Schedule A to the Support Agreement have been satisfied or waived prior to the Expiry Time, the Offeror will take up and pay for all the Common Shares deposited under the Offer as soon as reasonably possible and in any event not later than three (3) Business Days following the time at which it first becomes entitled to take up such securities under the Offer pursuant to applicable Laws. The obligation of the Offeror to take up and pay for the Common Shares under the Offer shall not be subject to any conditions except those conditions set out in Schedule A to the Support Agreement.

1.3 Conditions

The conditions to the making of the Offer are set out in Section 2.2 of the Support Agreement and the conditions of the Offer are set out in Schedule A to the Support Agreement.

ARTICLE 2

REPRESENTATIONS AND WARRANTIES

2.1 Representations and Warranties of the Seller

The Seller represents and warrants to and in favour of the Offeror as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and acknowledges that the Offeror is relying upon such representations and warranties in connection with the matters contemplated by this Agreement:

(a) Ownership, etc. The Seller is either (i) the legal and beneficial owner of, or (ii) the beneficial owner exercising control and direction over (but not the holder of record of) all of the Seller’s Securities. The only securities of the Company legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, are those listed on Appendix I to this Agreement. For greater certainty the term “Seller’s Securities” as used herein, includes the Common Shares and Convertible Securities listed on Appendix I and any securities of the Company into which they may be converted through the exercise, conversion or exchange of any Seller’s Securities. Except for the securities set out in Appendix I, the Seller has no agreement or option, or right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase or acquisition by the Seller or transfer to the Seller of additional securities of the Company (other than any agreements or amendments that the Seller may enter into to facilitate the exercise, cancellation or surrender of its Options, if any, as contemplated under the Support Agreement).

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

securityholders’ agreement, voting trust or other agreement affecting the Seller’s Securities or the ability of the Seller (or, after the acquisition by the Offeror pursuant to the Offer, the Offeror) to exercise all ownership rights thereto, including the voting of any such Seller’s Securities or any securities of the Company for which the Seller’s Securities may be exercised, converted or exchanged.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate, made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

- 3 -

(h) Existence and Authorization. If the Seller is not an individual, the Seller is validly existing under the laws of its jurisdiction of formation, continuance, incorporation or organization and has all necessary power, authority and capacity to enter into this Agreement and to carry out its obligations hereunder.

(i) Execution and Delivery. This Agreement has been duly executed and delivered by the Seller and constitutes a legal, valid and binding obligation of the Seller enforceable against it in accordance with its terms except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution.

2.2 Representations and Warranties of the Offeror

The Offeror represents and warrants as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and, where applicable, covenants to the Seller as follows and acknowledges that the Seller is relying upon these representations, warranties and covenants in connection with the entering into of this Agreement:

(a) the Offeror is validly existing under the laws of Canada and has the requisite power and authority to enter into this Agreement and to perform its obligations hereunder and under the Support Agreement;

(c) none of the execution and delivery by the Offeror of this Agreement, the Support Agreement or the performance of its obligations hereunder or thereunder will result in a breach of (i) the constating documents of the Offeror; (ii) any agreement or instrument to which the Offeror is a party or by which the Offeror or any of its property or assets is bound; (iii) any judgment, decree, order or award of any Governmental Authority applicable to the Offeror; or (iv) subject to receipt of the approval of the TSX and NYSE with respect to the listing of the Offeror Shares, any Law applicable to the Offeror; and

(d) the Offeror Shares to be issued pursuant to the Offer will, when issued pursuant to the Offer, be duly and validly issued as fully paid and non-assessable common shares in the capital of the Offeror; the Offeror has sufficient cash on-hand available to enable it to satisfy the aggregate cash consideration payable by the Offeror pursuant to the Offer.

B. The Seller is the registered and/or direct or indirect beneficial owner of, or exercises control or direction over, the issued and outstanding Common Shares and options, restricted share units and warrants to acquire Common Shares, as described more particularly in Appendix I hereto;

C. This Agreement sets out the terms and conditions of the Seller’s agreement to (i) support the Offer, (ii) exercise, convert or exchange all Convertible Securities (other than out-of-the money Convertible Securities) presently or subsequently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, (iii) deposit or cause to be deposited irrevocably under the Offer all Common Shares presently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, and all Common Shares subsequently legally or beneficially acquired by the Seller or over which the Seller will have control or direction, including Common Shares acquired upon exercise or exchange of Convertible Securities (collectively, the “Seller’s Securities”), and (iv) surrender for cancellation all out-of-the-money Convertible Securities;

D. The Offeror is relying on the covenants, representations and warranties of the Seller set forth in this Agreement in connection with the Offeror’s execution and delivery of the Support Agreement; and

E. Capitalized terms used herein but not otherwise defined herein have the meanings ascribed to such terms in the Support Agreement.

NOW THEREFORE in consideration of the Offeror agreeing to make the Offer, and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the Offeror and the Seller agree as follows:

Provided all conditions to the Offer set out in Schedule A to the Support Agreement have been satisfied or waived prior to the Expiry Time, the Offeror will take up and pay for all the Common Shares deposited under the Offer as soon as reasonably possible and in any event not later than three (3) Business Days following the time at which it first becomes entitled to take up such securities under the Offer pursuant to applicable Laws. The obligation of the Offeror to take up and pay for the Common Shares under the Offer shall not be subject to any conditions except those conditions set out in Schedule A to the Support Agreement.

REPRESENTATIONS AND WARRANTIES

2.1 Representations and Warranties of the Seller

The Seller represents and warrants to and in favour of the Offeror as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and acknowledges that the Offeror is relying upon such representations and warranties in connection with the matters contemplated by this Agreement:

(a) Ownership, etc. The Seller is either (i) the legal and beneficial owner of, or (ii) the beneficial owner exercising control and direction over (but not the holder of record of) all of the Seller’s Securities. The only securities of the Company legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, are those listed on Appendix I to this Agreement. For greater certainty the term “Seller’s Securities” as used herein, includes the Common Shares and Convertible Securities listed on Appendix I and any securities of the Company into which they may be converted through the exercise, conversion or exchange of any Seller’s Securities. Except for the securities set out in Appendix I, the Seller has no agreement or option, or right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase or acquisition by the Seller or transfer to the Seller of additional securities of the Company (other than any agreements or amendments that the Seller may enter into to facilitate the exercise, cancellation or surrender of its Options, if any, as contemplated under the Support Agreement).

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

securityholders’ agreement, voting trust or other agreement affecting the Seller’s Securities or the ability of the Seller (or, after the acquisition by the Offeror pursuant to the Offer, the Offeror) to exercise all ownership rights thereto, including the voting of any such Seller’s Securities or any securities of the Company for which the Seller’s Securities may be exercised, converted or exchanged.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate, made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

- 3 -

(h) Existence and Authorization. If the Seller is not an individual, the Seller is validly existing under the laws of its jurisdiction of formation, continuance, incorporation or organization and has all necessary power, authority and capacity to enter into this Agreement and to carry out its obligations hereunder.

(i) Execution and Delivery. This Agreement has been duly executed and delivered by the Seller and constitutes a legal, valid and binding obligation of the Seller enforceable against it in accordance with its terms except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution.

2.2 Representations and Warranties of the Offeror

The Offeror represents and warrants as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and, where applicable, covenants to the Seller as follows and acknowledges that the Seller is relying upon these representations, warranties and covenants in connection with the entering into of this Agreement:

(a) the Offeror is validly existing under the laws of Canada and has the requisite power and authority to enter into this Agreement and to perform its obligations hereunder and under the Support Agreement;

(b) this Agreement has been duly executed and delivered by the Offeror and constitutes a legal, valid and binding obligation, enforceable by the Seller against the Offeror in accordance with its terms, except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution;

(c) none of the execution and delivery by the Offeror of this Agreement, the Support Agreement or the performance of its obligations hereunder or thereunder will result in a breach of (i) the constating documents of the Offeror; (ii) any agreement or instrument to which the Offeror is a party or by which the Offeror or any of its property or assets is bound; (iii) any judgment, decree, order or award of any Governmental Authority applicable to the Offeror; or (iv) subject to receipt of the approval of the TSX and NYSE with respect to the listing of the Offeror Shares, any Law applicable to the Offeror; and

(d) the Offeror Shares to be issued pursuant to the Offer will, when issued pursuant to the Offer, be duly and validly issued as fully paid and non-assessable common shares in the capital of the Offeror; the Offeror has sufficient cash on-hand available to enable it to satisfy the aggregate cash consideration payable by the Offeror pursuant to the Offer.

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

securityholders’ agreement, voting trust or other agreement affecting the Seller’s Securities or the ability of the Seller (or, after the acquisition by the Offeror pursuant to the Offer, the Offeror) to exercise all ownership rights thereto, including the voting of any such Seller’s Securities or any securities of the Company for which the Seller’s Securities may be exercised, converted or exchanged.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller is a sophisticated seller with respect to the Seller’s Securities and has adequate information concerning the business and financial condition of the Company to make an informed decision regarding the sale of the Seller’s Securities and has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate,

- 3 -

made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

(h) Existence and Authorization. If the Seller is not an individual, the Seller is validly existing under the laws of its jurisdiction of formation, continuance, incorporation or organization and has all necessary power, authority and capacity to enter into this Agreement and to carry out its obligations hereunder.

(i) Execution and Delivery.

(c) none of the execution and delivery by the Offeror of this Agreement, the Support Agreement or the performance of its obligations hereunder or thereunder will result in a breach of (i) the constating documents of the Offeror; (ii) any agreement or instrument to which the Offeror is a party or by which the Offeror or any of its property or assets is bound; (iii) any judgment, decree, order or award of any Governmental Authority applicable to the Offeror; or (iv) subject to receipt of the approval of the TSX and NYSE with respect to the listing of the Offeror Shares, any Law applicable to the Offeror; and

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

securityholders’ agreement, voting trust or other agreement affecting the Seller’s Securities or the ability of the Seller (or, after the acquisition by the Offeror pursuant to the Offer, the Offeror) to exercise all ownership rights thereto, including the voting of any such Seller’s Securities or any securities of the Company for which the Seller’s Securities may be exercised, converted or exchanged.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate, made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

B. The Seller is the registered and/or direct or indirect beneficial owner of, or exercises control or direction over, the issued and outstanding Common Shares and options, restricted share units and warrants to acquire Common Shares, as described more particularly in Appendix I hereto;

C. This Agreement sets out the terms and conditions of the Seller’s agreement to (i) support the Offer, (ii) exercise, convert or exchange all Convertible Securities (other than out-of-the money Convertible Securities) presently or subsequently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, (iii) deposit or cause to be deposited irrevocably under the Offer all Common Shares presently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, and all Common Shares subsequently legally or beneficially acquired by the Seller or over which the Seller will have control or direction, including Common Shares acquired upon exercise or exchange of Convertible Securities (collectively, the “Seller’s Securities”), and (iv) surrender for cancellation all out-of-the-money Convertible Securities;

D. The Offeror is relying on the covenants, representations and warranties of the Seller set forth in this Agreement in connection with the Offeror’s execution and delivery of the Support Agreement; and

E. Capitalized terms used herein but not otherwise defined herein have the meanings ascribed to such terms in the Support Agreement.

Provided all conditions to the Offer set out in Schedule A to the Support Agreement have been satisfied or waived, the Offeror will take up and pay for all the Common Shares tendered under the Offer as soon as reasonably possible and in any event not later than three (3) Business Days following the time at which it first becomes entitled to take up such securities under the Offer pursuant to applicable Laws.

REPRESENTATIONS AND WARRANTIES

2.1 Representations and Warranties of the Seller

The Seller represents and warrants to and in favour of the Offeror as follows as at the date hereof and immediately prior to the time of which the Seller’s Securities are taken up and paid for under the Offer, and acknowledges that the Offeror is relying upon such representations and warranties in connection with the matters contemplated by this Agreement:

(a) Ownership, etc. The Seller is either (i) the legal and beneficial owner of, or (ii) the beneficial owner exercising control and direction over (but not the holder of record of) all of the Seller’s Securities. The only securities of the Company legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, are those listed on Appendix I to this Agreement. For greater certainty the term “Seller’s Securities” as used herein, includes the Common Shares and Convertible Securities listed on Appendix I and any securities of the Company into which they may be converted through the exercise, conversion or exchange of any Seller’s Securities. Except for the securities set out in Appendix I, the Seller has no agreement or option, or right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase or acquisition by the Seller or transfer to the Seller of additional securities of the Company (other than any agreements or amendments that the Seller may enter into to facilitate the exercise, cancellation or surrender of its Options, if any, as contemplated under the Support Agreement).

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

securityholders’ agreement, voting trust or other agreement affecting the Seller’s Securities or the ability of the Seller (or, after the acquisition by the Offeror pursuant to the Offer, the Offeror) to exercise all ownership rights thereto, including the voting of any such Seller’s Securities or any securities of the Company for which the Seller’s Securities may be exercised, converted or exchanged.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller is a sophisticated seller with respect to the Seller’s Securities and has adequate information concerning the business and financial condition of the Company to make an informed decision regarding the sale of the Seller’s Securities and has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate,

- 3 -

made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

(h) Existence and Authorization. If the Seller is not an individual, the Seller is validly existing under the laws of its jurisdiction of formation, continuance, incorporation or organization and has all necessary power, authority and capacity to enter into this Agreement and to carry out its obligations hereunder.

(i) Execution and Delivery. This Agreement has been duly executed and delivered by the Seller and constitutes a legal, valid and binding obligation of the Seller enforceable against it in accordance with its terms except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution.

2.2 Representations and Warranties of the Offeror

The Offeror represents, warrants and, where applicable, covenants to the Seller as follows and acknowledges that the Seller is relying upon these representations, warranties and covenants in connection with the entering into of this Agreement:

(a) the Offeror is validly existing under the laws of Canada and has the requisite power and authority to enter into this Agreement and to perform its obligations hereunder and under the Support Agreement;

(c) none of the execution and delivery by the Offeror of this Agreement, the Support Agreement or the performance of its obligations hereunder or thereunder will result in a breach of (i) the constating documents of the Offeror; (ii) any agreement or instrument to which the Offeror is a party or by which the Offeror or any of its property or assets is bound; (iii) any judgment, decree, order or award of any Governmental Authority applicable to the Offeror; or (iv) subject to receipt of the approval of the TSX and NYSE with respect to the listing of the Offeror Shares, any Law applicable to the Offeror; and

(d) the Offeror Shares to be issued pursuant to the Offer will, when issued pursuant to the Offer, be duly and validly issued as fully paid and non-assessable common shares in the capital of the Offeror; the Offeror has sufficient cash on-hand available to enable it to satisfy the aggregate cash consideration payable by the Offeror pursuant to the Offer.

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller is a sophisticated seller with respect to the Seller’s Securities and has adequate information concerning the business and financial condition of the Company to make an informed decision regarding the sale of the Seller’s Securities and has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate,

- 3 -

made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

References to “Common Shares” and “Seller’s Securities” include any securities into which the Common Shares and other Convertible Securities of the Company may be reclassified, subdivided, consolidated or converted and any rights and benefits arising therefrom, including any distributions of securities which may be declared in respect of such Company Securities.

LOCK UP AGREEMENT

THIS LOCK-UP AGREEMENT (this “Agreement”) dated January 9, 2011 between HudBay Minerals Inc. (the “Offeror”), a corporation governed by the laws of Canada, and Chris Reynolds, an individual resident in the City of Oakville (the “Seller”).

WHEREAS:

A. The Offeror is willing to make the Offer on the terms and subject to the conditions set out in the support agreement (as the same may be amended, modified or supplemented from time to time, the “Support Agreement”) with the Company;

B. The Seller is the registered and/or direct or indirect beneficial owner of, or exercises control or direction over, the issued and outstanding Common Shares and options, restricted share units and warrants to acquire Common Shares, as described more particularly in Appendix I hereto;

C. This Agreement sets out the terms and conditions of the Seller’s agreement to (i) support the Offer, (ii) exercise, convert or exchange all Convertible Securities (other than out-of-the money Convertible Securities) presently or subsequently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, (iii) deposit or cause to be deposited irrevocably under the Offer all Common Shares presently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, and all Common Shares subsequently legally or beneficially acquired by the Seller or over which the Seller will have control or direction, including Common Shares acquired upon exercise or exchange of Convertible Securities (collectively, the “Seller’s Securities”), and (iv) surrender for cancellation all out-of-the-money Convertible Securities;

D. The Offeror is relying on the covenants, representations and warranties of the Seller set forth in this Agreement in connection with the Offeror’s execution and delivery of the Support Agreement; and

E. Capitalized terms used herein but not otherwise defined herein have the meanings ascribed to such terms in the Support Agreement.

NOW THEREFORE in consideration of the Offeror agreeing to make the Offer, and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the Offeror and the Seller agree as follows:

ARTICLE 1

OFFER

1.1 Offer for Common Shares

The Offeror will publicly announce its intention to make the Offer and make the Offer on the terms and subject to the conditions set out in the Support Agreement.

1.2 Take-Up and Payment

Provided all conditions to the Offer set out in Schedule A to the Support Agreement have been satisfied or waived prior to the Expiry Time, the Offeror will take up and pay for all the Common Shares deposited under the Offer as soon as reasonably possible and in any event not later than three (3) Business Days following the time at which it first becomes entitled to take up such securities under the Offer pursuant to applicable Laws. The obligation of the Offeror to take up and pay for the Common Shares under the Offer shall not be subject to any conditions except those conditions set out in Schedule A to the Support Agreement.

1.3 Conditions

The conditions to the making of the Offer are set out in Section 2.2 of the Support Agreement and the conditions of the Offer are set out in Schedule A to the Support Agreement. All such conditions are for the sole benefit of the Offeror and the Offeror may, in its sole discretion, modify or waive any such term or condition, subject to the terms of the Support Agreement.

ARTICLE 2

REPRESENTATIONS AND WARRANTIES

2.1 Representations and Warranties of the Seller

The Seller represents and warrants to and in favour of the Offeror as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and acknowledges that the Offeror is relying upon such representations and warranties in connection with the matters contemplated by this Agreement:

(a) Ownership, etc. The Seller is either (i) the legal and beneficial owner of, or (ii) the beneficial owner exercising control and direction over (but not the holder of record of) all of the Seller’s Securities. The only securities of the Company legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, are those listed on Appendix I to this Agreement. For greater certainty the term “Seller’s Securities” as used herein, includes the Common Shares and Convertible Securities listed on Appendix I and any securities of the Company into which they may be converted through the exercise, conversion or exchange of any Seller’s Securities. Except for the securities set out in Appendix I, the Seller has no agreement or option, or right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase or acquisition by the Seller or transfer to the Seller of additional securities of the Company (other than any agreements or amendments that the Seller may enter into to facilitate the exercise, cancellation or surrender of its Options, if any, as contemplated under the Support Agreement).

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

securityholders’ agreement, voting trust or other agreement affecting the Seller’s Securities or the ability of the Seller (or, after the acquisition by the Offeror pursuant to the Offer, the Offeror) to exercise all ownership rights thereto, including the voting of any such Seller’s Securities or any securities of the Company for which the Seller’s Securities may be exercised, converted or exchanged.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate, made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

- 3 -

(h) Existence and Authorization. If the Seller is not an individual, the Seller is validly existing under the laws of its jurisdiction of formation, continuance, incorporation or organization and has all necessary power, authority and capacity to enter into this Agreement and to carry out its obligations hereunder.

(i) Execution and Delivery. This Agreement has been duly executed and delivered by the Seller and constitutes a legal, valid and binding obligation of the Seller enforceable against it in accordance with its terms except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution.

2.2 Representations and Warranties of the Offeror

The Offeror represents and warrants as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and, where applicable, covenants to the Seller as follows and acknowledges that the Seller is relying upon these representations, warranties and covenants in connection with the entering into of this Agreement:

(a) the Offeror is validly existing under the laws of Canada and has the requisite power and authority to enter into this Agreement and to perform its obligations hereunder and under the Support Agreement;

(b) this Agreement has been duly executed and delivered by the Offeror and constitutes a legal, valid and binding obligation, enforceable by the Seller against the Offeror in accordance with its terms, except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution;

(c) none of the execution and delivery by the Offeror of this Agreement, the Support Agreement or the performance of its obligations hereunder or thereunder will result in a breach of (i) the constating documents of the Offeror; (ii) any agreement or instrument to which the Offeror is a party or by which the Offeror or any of its property or assets is bound; (iii) any judgment, decree, order or award of any Governmental Authority applicable to the Offeror; or (iv) subject to receipt of the approval of the TSX and NYSE with respect to the listing of the Offeror Shares, any Law applicable to the Offeror; and

(d) the Offeror Shares to be issued pursuant to the Offer will, when issued pursuant to the Offer, be duly and validly issued as fully paid and non-assessable common shares in the capital of the Offeror; the Offeror has sufficient cash on-hand available to enable it to satisfy the aggregate cash consideration payable by the Offeror pursuant to the Offer.

B. The Seller is the registered and/or direct or indirect beneficial owner of, or exercises control or direction over, the issued and outstanding Common Shares and options, restricted share units and warrants to acquire Common Shares, as described more particularly in Appendix I hereto;

C. This Agreement sets out the terms and conditions of the Seller’s agreement to (i) support the Offer, (ii) exercise, convert or exchange all Convertible Securities (other than out-of-the money Convertible Securities) presently or subsequently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, (iii) deposit or cause to be deposited irrevocably under the Offer all Common Shares presently legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, and all Common Shares subsequently legally or beneficially acquired by the Seller or over which the Seller will have control or direction, including Common Shares acquired upon exercise or exchange of Convertible Securities (collectively, the “Seller’s Securities”), and (iv) surrender for cancellation all out-of-the-money Convertible Securities;

D. The Offeror is relying on the covenants, representations and warranties of the Seller set forth in this Agreement in connection with the Offeror’s execution and delivery of the Support Agreement; and

REPRESENTATIONS AND WARRANTIES

2.1 Representations and Warranties of the Seller

The Seller represents and warrants to and in favour of the Offeror as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and acknowledges that the Offeror is relying upon such representations and warranties in connection with the matters contemplated by this Agreement:

(a) Ownership, etc. The Seller is either (i) the legal and beneficial owner of, or (ii) the beneficial owner exercising control and direction over (but not the holder of record of) all of the Seller’s Securities. The only securities of the Company legally or beneficially owned by the Seller, or over which the Seller exercises control or direction, are those listed on Appendix I to this Agreement. For greater certainty the term “Seller’s Securities” as used herein, includes the Common Shares and Convertible Securities listed on Appendix I and any securities of the Company into which they may be converted through the exercise, conversion or exchange of any Seller’s Securities. Except for the securities set out in Appendix I, the Seller has no agreement or option, or right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase or acquisition by the Seller or transfer to the Seller of additional securities of the Company (other than any agreements or amendments that the Seller may enter into to facilitate the exercise, cancellation or surrender of its Options, if any, as contemplated under the Support Agreement).

(b) Good Title. The Seller’s Securities will be transferred to and acquired by the Offeror pursuant to the Offer with good and marketable title, free and clear of any and all Encumbrances. The Seller’s Securities are not subject to any securityholders’ agreement, voting trust or similar agreement or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming a

- 2 -

securityholders’ agreement, voting trust or other agreement affecting the Seller’s Securities or the ability of the Seller (or, after the acquisition by the Offeror pursuant to the Offer, the Offeror) to exercise all ownership rights thereto, including the voting of any such Seller’s Securities or any securities of the Company for which the Seller’s Securities may be exercised, converted or exchanged.

(c) No Agreements. No Person, firm, corporation or other entity whatsoever has any agreement or option, or any right or privilege (whether by Laws, pre-emptive or contractual) capable of becoming an agreement or option, for the purchase, requisition or transfer from the Seller, or any registered holder of Seller’s Securities or any other Person, of any of the Seller’s Securities, or any interest therein or right thereto, except pursuant to this Agreement. Other than as disclosed in writing by the Seller to the Offeror, there does not exist any agreement, understanding or commitment giving rise to any obligations, financial or otherwise, on the part of the Company or any of its Affiliates to the Seller, or any Affiliates of the Seller as applicable (or any associates or insiders (as such terms are defined in the Securities Act (Ontario) of any of the foregoing).

(d) No Proceeding Pending. There is no claim, action, lawsuit, arbitration, mediation or other proceeding pending or threatened against the Seller, that relates or could relate to this Agreement or otherwise materially impairs or could materially impair the ability of the Seller to consummate the transactions contemplated hereby or the title of the Seller to any of the Seller’s Securities.

(e) Consents. There is no requirement of the Seller to make any filing with, give any notice to, or obtain any permit, licence, sanction, ruling, order, exemption or consent, approval or waiver of, any Governmental Authority or other Person (including the lapse, without objection, of a prescribed time under applicable Laws that states that a transaction may be implemented if a prescribed time lapses following the giving of notice) as a condition to the lawful completion of the transactions contemplated by this Agreement or the Offer, or the execution and delivery by the Seller and enforcement against the Seller of this Agreement.

(f) Non-Contravention. This Agreement and the completion of the transactions that it contemplates does not (and would not with the giving of notice, the lapse of time or the happening of any other event or condition) result in a breach or a violation of, or conflict with in any manner, or allow any other Person to exercise any rights under any of the terms or provisions of the constating documents and/or by-laws of the Seller, if applicable, or any agreement, contract or indenture to which the Seller is a party or by which the Seller’s property or the Seller’s Securities are bound, and will not result in the violation of any Laws.

(g) Sophisticated Seller. The Seller has independently and without reliance upon the Offeror, and based on such information as the Seller has deemed appropriate, made its own analysis and decision to enter into this Agreement. The Seller acknowledges that the Offeror has not made and does not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement.

- 3 -

(h) Existence and Authorization. If the Seller is not an individual, the Seller is validly existing under the laws of its jurisdiction of formation, continuance, incorporation or organization and has all necessary power, authority and capacity to enter into this Agreement and to carry out its obligations hereunder.

(i) Execution and Delivery. This Agreement has been duly executed and delivered by the Seller and constitutes a legal, valid and binding obligation of the Seller enforceable against it in accordance with its terms except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally, (ii) general equitable principles or (iii) limitations under applicable Laws in respect of rights of indemnity, contribution and waiver of contribution.

2.2 Representations and Warranties of the Offeror

The Offeror represents and warrants as follows as at the date hereof and immediately prior to the time at which the Seller’s Securities are taken up and paid for under the Offer, and, where applicable, covenants to the Seller as follows and acknowledges that the Seller is relying upon these representations, warranties and covenants in connection with the entering into of this Agreement:

(c) none of the execution and delivery by the Offeror of this Agreement, the Support Agreement or the performance of its obligations hereunder or thereunder will result in a breach of (i) the constating documents of the Offeror; (ii) any agreement or instrument to which the Offeror is a party or by which the Offeror or any of its property or assets is bound; (iii) any judgment, decree, order or award of any Governmental Authority applicable to the Offeror; or (iv) subject to receipt of the approval of the TSX and NYSE with respect to the listing of the Offeror Shares, any Law applicable to the Offeror; and

(d) the Offeror Shares to be issued pursuant to the Offer will, when issued pursuant to the Offer, be duly and validly issued as fully paid and non-assessable common shares in the capital of the Offeror; the Offeror has sufficient cash on-hand available to enable it to satisfy the aggregate cash consideration payable by the Offeror pursuant to the Offer.
