(c) Prior to the printing of the Circular, Offeror shall provide Miramar and its counsel with a reasonable opportunity to review and comment on it, recognizing that whether or not such comments are appropriate will be determined by Offeror, acting reasonably.

(e) The Offer shall be made in accordance with Applicable Securities Laws and shall expire not earlier than midnight (Toronto time) on the 36^th day after the date that the Offer was first commenced within the meaning of the Securities Act, subject to the right of Offeror to extend (not more than twice unless Common Shares deposited under the Offer have, on or before the third or subsequent extension, been taken up) from time to time the period during which Common Shares may be deposited under the Offer (such time on such date, as the same may be extended, is referred to in this Agreement as the “Expiry Time”). The Offer shall be subject to the conditions set forth in Schedule A to this Agreement. Offeror shall use all reasonable efforts to consummate the Offer, subject to the terms and conditions hereof and thereof.

(f) Offeror may, in its sole discretion, modify or waive any term or condition of the Offer; provided that Offeror shall not, without the prior consent of Miramar, not to be unreasonably withheld, increase or decrease the Minimum Tender Condition, impose additional conditions to the Offer, decrease the consideration per Common Share, decrease the number of Common Shares in respect of which the Offer is made, change the form of consideration payable under the Offer (other than to increase the total consideration per Common Share and/or add additional consideration or consideration alternatives) or otherwise vary the Offer or any terms or conditions thereof (which, for greater certainty, does not include a waiver of a condition) in a manner that is adverse to the Shareholders.

(g) The obligation of Offeror to mail the Offer is conditional on the prior satisfaction of the following conditions, all of which conditions are included for the sole benefit of Offeror and any or all of which may be waived by Offeror in whole or in part in its sole discretion (other than the condition set out in Section 2.1(g)(iv) below, which must be waived if Offeror has failed to use its commercially reasonable efforts to obtain such assurances) without prejudice to any other right it may have under this Agreement and which conditions shall be deemed to have been waived by the making of the Offer:

Miramar and the Offeror further agree that the provisions of Section 8 of the Subscription Agreement cease to apply to the Offeror and its affiliates in their entirety until the earlier of (i) the Expiry Time (if Offeror has not publicly announced its intention to take up Common Shares deposited under the Offer), and (ii) the acquisition by Offeror of Common Shares that result in Offeror and its affiliates beneficially owning at least 50.01% of the Common Shares.

2.4 Outstanding Stock Options

The Board of Directors has resolved to (i) permit all persons holding Options, which by their terms are otherwise currently exercisable or not, to exercise or surrender such Options, including, if permitted by the Stock Exchanges, by causing the vesting thereof to be accelerated, by way of cashless exercise, which exercise may be conditional upon the Offeror taking up and paying for Common Shares under the Offer; and (ii) cause each outstanding Option that has not been exercised (including any conditional exercise as contemplated in (i) above) to be terminated, upon the take-up and payment by the Offeror pursuant to the Offer of such number of Common Shares that satisfies the Minimum Tender Condition.

2.5 Directors

Promptly upon the take-up and payment by the Offeror pursuant to the Offer of such number of Common Shares that, together with the Common Shares held by the Offeror and its affiliates, constitutes at least 66 ²/3% of the outstanding Common Shares (calculated on a fully-diluted basis), the Offeror shall designate the directors of the Board of Directors, and any committees thereof, and the Company shall not frustrate the Offeror’s attempts to do so, and covenants to cooperate with the Offeror, subject to applicable Laws, to obtain the resignation of the then incumbent directors effective on the date, not more than five business days later, specified by the Offeror and facilitate the Offeror’s designees to be elected or appointed to the Board of Directors.

2.6 Subsequent Acquisition Transaction

If, within 120 days after the date of the Offer, the Offer has been accepted by holders of not less than 90% of the outstanding Common Shares as at the Expiry Time, excluding Common Shares held by or on behalf of Offeror or an “affiliate” (as such term is defined in the BCBCA) of Offeror at the date of the Offer, Offeror may, to the extent possible, acquire (a “Compulsory Acquisition”) the remainder of the Common Shares from those Shareholders who have not accepted the Offer pursuant to section 300 of the BCBCA. If that statutory right of acquisition is not available or Offeror chooses not to avail itself of such statutory right of acquisition, Offeror will use its commercially reasonable efforts to pursue other means of acquiring the remaining Common Shares not tendered to the Offer, provided that the consideration per Common Share offered in connection with such other means of acquiring such Common Shares shall be at least equivalent in value to the consideration per Common Share offered under the Offer. If Offeror takes up and pays for Common Shares under the Offer in such number as satisfy the original Minimum Tender Condition, Miramar will assist Offeror in connection with any proposed amalgamation, statutory arrangement, amendment to articles, consolidation, capital reorganization or other transaction involving Miramar, Offeror or an affiliate of the Offeror that Offeror may, in its sole discretion, undertake to pursue (a “Subsequent Acquisition Transaction”) to acquire the remaining Common Shares, provided that the consideration per Common Share offered in connection with the Subsequent Acquisition Transaction is at least equivalent in value to the consideration per Common Share offered under the Offer.

Each party to this Agreement, where appropriate, will reasonably co-operate with the other in taking such actions.

(b) In furtherance and not in limitation of Section 6.1(a) and subject to the other Subsections of this Section, and except with respect to any specific limitations set forth in this Section concerning the actions which the Offeror is required to take in order to obtain necessary approvals or remove any opposition that might be imposed or raised by a Governmental Entity pursuant to any Regulatory Laws with respect to any of the Contemplated Transactions, each party to this Agreement agrees to make:

(i) the appropriate pre-merger notifications and/or application pursuant to Part IX of the Competition Act (Canada) (“Competition Act”) and any other submissions in connection with the Competition Act as may be appropriate and advisable as promptly as reasonably practicable and to supply as promptly as reasonably practicable any additional information and documentary material that may be reasonably requested by the Canadian Commissioner of Competition (the “Commissioner”) and to take all other reasonable actions necessary, proper or advisable to cause the expiration or termination of any applicable waiting periods and to obtain any approval, exemption or notification required or sought to be obtained from the Commissioner in order to complete the Offer, any Compulsory Acquisition or any Subsequent Acquisition Transaction as soon as reasonably practicable; and

(d) Without limiting the generality of Section 6.1, if determined to be required by counsel to Offeror, Offeror will make an application for review required under Part IV of the Investment Canada Act and/or any other submissions, notifications or filings pursuant to such legislation as may be appropriate and advisable as promptly as reasonably practicable and to supply as promptly as reasonably practicable any additional

- 19 -

information and documentary material that may be reasonably required by the Director of Investments and/or the Minister of Industry or their designates. Each party shall use its commercially reasonable efforts, subject to all applicable Regulatory Laws relating thereto and to the exchange of privileged, confidential or competitively-sensitive information, to (i) provide the other parties with information on a timely basis, which is required in order to make an application for review required under Part IV of the Investment Canada Act and/or any other submissions, notifications or filings pursuant to such legislation as may be appropriate and advisable (ii) the keep the other parties (or their external counsel in respect of competitively sensitive, privileged or confidential matters) promptly informed of any material communication received by such party in respect of the application for review under the Investment Canada Act and any material communication received or given in connection with any proceeding by a private party, and (iii) consult with the other parties (or their external counsel in respect of competitively sensitive, privileged or confidential matters) prior to making any filings or submissions or participating in any substantive meeting or discussion in respect of the application for review under the Investment Canada Act in respect of any filings, investigation or inquiry concerning the Offer, any Compulsory Acquisition or any Subsequent Acquisition Transaction.

(e) Other than to the extent any Regulatory Laws expressly require Miramar or any of the Miramar Subsidiaries to obtain any consent of any Governmental Entity or to make any filing with any Governmental Entity, Offeror shall be solely responsible for making all such filings and otherwise pursuing all Competition Clearances and any other consents from Governmental Entities which are required to consummate the Offer (including under the Investment Canada Act), any Compulsory Acquisition or any Subsequent Acquisition Transaction or deemed by Offeror to be appropriate or advisable. Miramar shall fully co-operate with Offeror in pursuing all Competition Clearances and any other clearances contemplated by Section 6.1(b) (including under the Investment Canada Act) and to the extent it is so required to obtain a consent or make a filing it shall do so only after the prior review thereof and concurrence thereto by and in co-ordination with Offeror.

(f) All filing fees required in connection with the notification of the Offer, any Compulsory Acquisition or any Subsequent Acquisition Transaction or the application for or prosecution of any consent, approval, authorization, registration, filing or submission in accordance with this Section 6.1 shall be borne by the party required to obtain or make such consent, approval, authorization, registration, filing or submission. Unless otherwise provided, all other fees, expenses and disbursements (including the costs of preparation of any such filings and fees and expenses of legal counsel) incurred in connection with the matters referred to in this Section 6.1 shall be borne by Offeror if incurred by or on its behalf and by Miramar if incurred by or on behalf of Miramar.

(g) Each of Offeror and Miramar shall promptly notify the other if at any time before the Expiry Time it becomes aware that the Circular, the Directors’ Circular, an application for an order, any registration, consent, circular or approval, registration statement or any other filing under companies, corporations or Applicable Securities Laws contains an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements contained therein not misleading in light of the circumstances in which they are made, or that otherwise requires an amendment or supplement to the Circular, the Directors’ Circular, such application, registration statement or filing, and Offeror and Miramar shall co-operate in the preparation of any

- 20 -

amendment or supplement to the Circular, the Directors’ Circular, application, registration statement or filing, as required.

6.2 No Solicitations, Opportunity to Match, Etc.

(a) On and after the date hereof, except as otherwise provided in this Agreement, Miramar shall not, and shall cause each of the Miramar Subsidiaries not to, directly or indirectly, through any officer, director, employee, representative (including for greater certainty any financial or other advisors) of Miramar or any Miramar Subsidiary, or consultant to Miramar previously identified to Offeror (collectively, the “Miramar Parties”), take any action of any kind that might reasonably be expected to, directly or indirectly, interfere with the successful acquisition of Common Shares by Offeror under the Offer, any Compulsory Acquisition, any Subsequent Acquisition Transaction or any Alternative Transaction, including any action to:

(i) make, solicit, assist, initiate, encourage or otherwise facilitate (including by way of furnishing information, permitting any visit to any facilities or properties of Miramar or any Miramar Subsidiary or mineral property, or entering into any form of written or oral agreement, arrangement or understanding) the initiation of any Acquisition Proposal or inquiries relating to an Acquisition Proposal;

(ii) engage or participate in any discussions or negotiations regarding, or provide any information with respect to, any Acquisition Proposal or otherwise co-operate in any way with, or assist or participate in, facilitate or encourage, any effort or attempt by any other person to do or seek to do any of the foregoing, provided that, for greater certainty, Miramar may advise any person making an unsolicited Acquisition Proposal that such Acquisition Proposal does not constitute a Superior Proposal when the Board of Directors has so determined;

(iii) withdraw, modify or qualify, or propose publicly to withdraw, modify or qualify, in any manner adverse to Offeror, the approval or recommendation of the Board of Directors or any committee thereof of this Agreement or the Offer;

(iv) approve or recommend, or propose publicly to approve or recommend, any Acquisition Proposal; or

(v) accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement in principle, agreement, arrangement or undertaking related to any Acquisition Proposal,

provided, however, that nothing contained in this Section 6.2(a) or any other provision of this Agreement shall prevent the Board of Directors from, and the Board of Directors shall be permitted to:

(A) withdraw, modify or qualify (or propose to withdraw, modify or qualify) in any manner adverse to Offeror the approval or recommendation of the Offer; or

(B) engage in discussions or negotiations with any person in response to an Acquisition Proposal made by any such person,

- 21 -

- 22 -

all Shareholders the same consideration in form and amount per Common Share to be purchased or otherwise acquired (an “Unsolicited Proposal”), and with respect to which (x) the Board of Directors determines in good faith after receipt of advice from its Financial Advisors that such Acquisition Proposal would, if consummated in accordance with its terms (but not assuming away any risk of non-completion), reasonably be expected to result in a Superior Proposal (notwithstanding that such proposal may be subject to a due diligence condition or a financing condition, or both), and (y) in the opinion of the Board of Directors, acting in good faith and on advice of its outside legal advisors, the failure to provide such party with access to information regarding Miramar would be inconsistent with the fiduciary duties of the Board of Directors, then, and only in such case, Miramar may:

(i) provide such person with access to information regarding Miramar, and/or

(ii) engage in discussions with such person and its officers, directors and representatives (including any financial or other advisers) in response to a proposal to effect an Acquisition Proposal that would reasonably be expected to result in a Superior Proposal,

As soon as possible following the date of this Agreement and, in any event, within five business days from the date of this Agreement (or, where information has been provided pursuant to Section 6.2(b)(i), promptly following the Effective Time), Miramar shall request the return or destruction of all information provided to any third parties who have entered into a confidentiality agreement with Miramar relating to any potential Acquisition Proposal and shall use all reasonable efforts to ensure that such requests are honoured in accordance with the terms of such confidentiality agreements.

- 23 -

(d) Miramar shall not waive, release any person from, or fail to enforce on a timely basis any obligation under any confidentiality agreement or standstill agreement or amend any such agreement, except to allow such person to propose confidentially to the Board of Directors (but without restricting Miramar from making public disclosure to the extent required by Applicable Securities Laws) an Unsolicited Proposal or otherwise make a Superior Proposal, provided in any case that the remaining provisions of this Agreement are complied with.

(e) From and after the date of this Agreement, Miramar shall promptly (and in any event within 24 hours after it has received any proposal, inquiry, offer or request) notify Offeror, at first orally and then in writing, of any proposal, inquiry, offer (or any amendment to any of the foregoing) or request of which Miramar’s directors, officers, employees, representatives or agents are or become aware (i) relating to or constituting an Acquisition Proposal, (ii) relating to any request for discussions or negotiations, and/or any request for non-public information relating to Miramar, any Miramar Subsidiary or any mineral property or contractual or legal rights, (iii) relating to any request for access to properties, books and records or a list of the Shareholders or the shareholders of Miramar Subsidiaries, or (iv) any request for representation on the Board of Directors, or any amendments to the foregoing.

Miramar shall keep Offeror promptly and fully informed of the status, including any change to the terms, of any such proposal, inquiry, offer or request, or any amendment to the foregoing, and will respond promptly to all inquiries by Offeror with respect thereto.

(f) Miramar shall ensure that the Miramar Parties are aware of the provisions of this Section 6.2 and agree to be bound thereby, and Miramar shall be responsible for any breach of this Section 6.2 by the Miramar Parties.

(g) Miramar shall not accept, approve or recommend, nor enter into any agreement (other than a confidentiality agreement permitted by this Section 6.2 relating to an Acquisition Proposal) unless:

(i) the Acquisition Proposal constitutes a Superior Proposal;

(ii) Miramar has complied with Sections 6.2(a) through 6.2(h), inclusive;

(iii) Miramar has provided Offeror with (A) notice in writing that there is a Superior Proposal, and (B) all documentation related to and detailing the Superior Proposal (including a copy of the confidentiality agreement between Miramar and the person making the Superior Proposal if not previously delivered), in each case at least five business days prior to the date on which the Board of Directors proposes to accept, approve, recommend or enter into any agreement relating to such Superior Proposal;

(iv) five business days shall have elapsed from the later of the date Offeror received the notice and documentation referred to in Section 6.2(g)(iii) from Miramar in respect of the Acquisition Proposal and the date Offeror received notice of Miramar’s proposed determination to accept, approve, recommend or to enter into any agreement relating to such Superior Proposal, and, if Offeror has

- 24 -

proposed to amend the terms of this Agreement and the Offer in accordance with Section 6.2(h), the Board of Directors (after receiving advice from the Financial Advisors and outside legal counsel) shall have determined in good faith that the Acquisition Proposal is a Superior Proposal compared to the proposed amendment to the terms of the Offer by Offeror;

(v) Miramar concurrently terminates this Agreement pursuant to Section 7.1(k); and

(vi) Miramar has previously, or concurrently will have, paid to Offeror or the Offeror Assignee the Termination Payment.

(h) During the five business day periods referred to in Section 6.2(g)(iii) and Section 6.2(g)(iv) or such longer period as Miramar may approve for such purpose (the “Right to Match Period”), Offeror shall have the opportunity, but not the obligation, to propose to amend the terms of this Agreement and the Offer, and Miramar shall co-operate with Offeror with respect thereto, including negotiating in good faith with Offeror to enable Offeror to make such adjustments to the terms and conditions of this Agreement and the Offer as Offeror deems appropriate and as would enable Offeror to proceed with the Offer and any Contemplated Transactions on such adjusted terms. The Board of Directors shall review any proposal by Offeror to amend the terms of the Offer in order to determine, in good faith in the exercise of its fiduciary duties, whether Offeror’s proposal to amend the Offer would result in the Acquisition Proposal not being a Superior Proposal compared to the proposed amendment to the terms of the Offer.

(i) The Board of Directors shall promptly reaffirm its recommendation of the Offer by press release after any Acquisition Proposal is publicly announced or made and (A) the Board of Directors determines that the Acquisition Proposal is not a Superior Proposal; or (B) the Board of Directors determines that a proposed amendment to the terms of the Offer would result in the Acquisition Proposal not being a Superior Proposal, and Offeror has so amended the terms of the Offer. Offeror and its counsel and other advisors shall be given a reasonable opportunity to review and comment on the form and content of any such press release. Such press release shall state that the Board of Directors has determined that the Acquisition Proposal is not a Superior Proposal.

(j) Nothing in this Agreement shall prevent the Board of Directors from responding through a directors’ circular or otherwise as required by Applicable Securities Laws to an Acquisition Proposal that it determines is not a Superior Proposal. Offeror and its counsel shall be given a reasonable opportunity to review and comment on the form and content of any such directors’ circular prior to its printing, recognizing that whether or not such comments are appropriate will be determined by Miramar, acting reasonably.

(k) Each successive modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for purposes of Section 6.2.

6.3 Notification of Certain Matters

Each party shall give prompt notice to the other of:

(a) the occurrence or failure to occur of any event, which occurrence or failure would cause or may cause any representation or warranty on its part contained in this Agreement to be untrue or inaccurate at any time from the date hereof to the Effective Time; and

- 25 -

(b) any failure of such party, or any officer, director, employee, representative or agent thereof, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder.

6.4 Investigation by Offeror

Upon reasonable notice, Miramar agrees to provide Offeror and its representatives with reasonable access (without disruption to the conduct of Miramar’s business) during normal business hours to all books, records, information, corporate charts, tax documents, filings, memoranda, working papers and files and all other materials in its possession and control, including contracts, and access to the personnel of Miramar and the Miramar Subsidiaries on an as reasonably requested basis as well as reasonable access to the properties of Miramar and the Miramar Subsidiaries in order to allow Offeror to conduct such investigations as Offeror may consider necessary or advisable to confirm the accuracy of Miramar’s representations and warranties in this Agreement, for strategic planning and integration, for the structuring of any Pre-Acquisition Reorganization and for any other reasons reasonably relating to any Contemplated Transactions, and further agrees to assist Offeror in all reasonable ways in any such investigations that Offeror may wish to conduct. Any such investigation by Offeror and its advisors shall not mitigate, diminish or affect the representations and warranties of Miramar contained in this Agreement or any document or certificate given pursuant hereto.

6.5 Officers’ and Directors’ Insurance and Indemnification

(a) Offeror will, or will cause Miramar to, maintain in effect without any reduction in amount or scope for six years from the Effective Time customary policies of directors’ and officers’ liability insurance providing protection comparable to the protection provided by the policies maintained by Miramar and its Subsidiaries that are in effect immediately prior to the Effective Time and providing protection in respect of claims arising from facts or events which occurred on or prior to the Effective Time; provided, however, that Offeror will not be required, in order to maintain or cause to be maintained such directors’ and officers’ liability insurance policy, to pay an annual premium in excess of 200% of the cost 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 such amount, Offeror shall only be required to obtain or cause to be obtained as much coverage as can be obtained by paying an annual premium equal to 200% of such amount. Furthermore, prior to the Effective Time Miramar may, in the alternative, purchase run off directors’ and officers’ liability insurance for a period of up to seven years from the Effective Time provided that the premium will not exceed 200% of the premium currently charged to Miramar for directors’ and officer’s liability insurance, and in such event none of the Offeror, Miramar or any of its Subsidiaries will have any further obligation under this Section 6.5(a).

(b) Offeror agrees that it shall directly honour all rights to indemnification or exculpation now existing in favour of present and former officers and directors of Miramar and its Subsidiaries, which shall survive the completion of the Offer and the provisions of this Section 6.5 shall be binding, jointly and severally, on all successors of the Offeror.

6.6 Shareholder Claims

Miramar shall notify Offeror forthwith of any claim brought by (or threatened to be brought by) any present, former or purported holder of any securities of Miramar in connection with the Contemplated Transactions prior to the Effective Time. Miramar shall consult with Offeror prior to

- 26 -

settling any such claim prior to the Effective Time and shall not settle or compromise, or agree to settle or compromise any such claim prior to the Effective Date without the prior written consent of Offeror.

6.7 Required Securities Law Approvals

Offeror will promptly take such action, including obtaining any exemption orders, consents or approvals or filing any such documents, as may be required under Applicable Securities Laws to permit Offeror to make the Offer and perform Offeror’s other obligations hereunder, and Miramar shall co-operate in good faith in connection with any such action by Offeror.

6.8 Reorganization

Upon request by Offeror, Miramar shall:

(a) effect such reorganizations of its business, operations and assets or such other transactions as Offeror may request, acting reasonably (each a “Pre-Acquisition Reorganization”); and

(b) co-operate with Offeror and its advisors in order to determine the nature of the Pre-Acquisition Reorganizations that might be undertaken and the manner in which they might most effectively be undertaken; provided that the Pre-Acquisition Reorganizations:

(i) do not result in any breach by Miramar of any existing contract or commitment of Miramar or of any Law; or

(ii) would not reasonably be expected to impede or delay Offeror’s ability to take up and pay for the Common Shares tendered to the Offer.

Offeror shall provide written notice to Miramar of any proposed Pre-Acquisition Reorganization at least ten business days prior to the Expiry Time. Upon receipt of such notice, Offeror and Miramar shall co-operate and use commercially reasonable efforts to prepare prior to the Expiry Time all documentation necessary and do all such other acts and things as are necessary to give effect to such Pre-Acquisition Reorganization. Offeror agrees to waive any breach of a representation, warranty or covenant by Miramar where such breach is a result of an action taken by Miramar in good faith pursuant to a request by Offeror in accordance with this Section 6.8. The completion of any such Pre-Acquisition Reorganization shall be subject to the satisfaction or (where permitted by this Agreement) waiver of the conditions to the Offer set forth in Schedule A and shall be effected prior to any take-up by Offeror of Common Shares tendered to the Offer. If Offeror does not take up and pay for the Common Shares deposited under the Offer other than as a result of any occurrence, event or action described in Sections 7.1(g), 7.1(j) or 7.1(k), Offeror will reimburse Miramar for all reasonable fees and expenses incurred by Miramar and the Miramar Subsidiaries in considering and effecting the Pre-Acquisition Reorganization and shall be responsible for any reasonable fees and expenses of Miramar and the Miramar Subsidiaries for steps that the parties agree, acting reasonably, may be necessary to mitigate any material adverse effect that would result from any Pre-Acquisition Reorganization that was effected prior to the termination of the Agreement.

6.9 Transaction Structuring and Alternative Transaction

(a) Offeror and Miramar agree to co-operate in good faith and to take all reasonable steps and actions after the date hereof, as are not adverse to the party requested to take any

- 27 -

such step or action, to complete the Contemplated Transactions contemplated by this Agreement as promptly as practicable.

(b) In addition, in the event that:

(i) Offeror concludes, acting reasonably, that it is necessary or desirable to proceed with another form of transaction (such as a plan of arrangement or amalgamation) whereby Offeror or any of its affiliates would effectively acquire all of the Common Shares within approximately the same time periods and on economic terms and other terms and conditions (including, without limitation, tax treatment) and having consequences to Miramar and the Miramar Shareholders that are equivalent to or better than those contemplated by this Agreement (an “Alternative Transaction”), and

(ii) Miramar concludes, acting reasonably, that no action or actions required to be taken by it or by the Miramar Subsidiaries in connection with such Alternative Transaction (and not required to be taken in connection with the Offer) prior to the consummation thereof would result in a Material Adverse Effect in respect of Miramar,

Miramar agrees to support the completion of such Alternative Transaction in the same manner as the Offer and shall otherwise fulfill its covenants contained in this Agreement in respect of such Alternative Transaction.

6.10 Disclosure of Material Information upon Termination

If this Agreement is terminated prior to the Effective Time (other than pursuant to Section 7.1(h) or 7.1(i)), Miramar shall, within 5 business days of such termination, disclose all Material Information to the public generally by means of a material change report and a filing on Form 8-K or other periodic report required or permitted to be filed under Applicable Securities Laws. For purposes of this Section 6.10, “Material Information” shall mean all material and non-public information concerning Miramar or any of its Subsidiaries that has been furnished to Offeror or any of its affiliates, in written, electronic or other form, in connection with this Agreement, the Contemplated Transactions or the due diligence therefor.

ARTICLE 7

TERMINATION, AMENDMENT AND WAIVER

7.1 Termination

This Agreement may be terminated at any time prior to the Effective Time:

(a) by mutual written consent of Offeror and Miramar;

(b) by Miramar, if Offeror does not mail the Circular by the Latest Mailing Time;

(c) by Offeror on or after the Latest Mailing Time, if any condition to making the Offer for Offeror’s benefit is not satisfied or waived by such date other than as a result of a default by Offeror hereunder;

- 28 -

(d) by Offeror if the Minimum Tender Condition or any other condition of the Offer shall not be satisfied or waived at the Expiry Time of the Offer and Offeror shall not elect to waive such condition;

(e) by Offeror or Miramar, if Offeror does not take up and pay for the Common Shares deposited under the Offer by a date that is four months following the date of mailing of the Offer (as it may be extended, the “Outside Date”), provided that the right to terminate this Agreement pursuant to this clause shall not be available to the party seeking to terminate if any action of such party or its affiliates, or any failure of such party or its affiliates to perform any of its obligations under this Agreement required to be performed by it, shall have resulted in a condition contained in Schedule A to this Agreement not having been satisfied prior to the Outside Date; provided, however, that if Offeror’s take up and payment for Common Shares deposited under the Offer is delayed by an injunction or order made by a Governmental Entity of competent jurisdiction, or Offeror not having obtained any waiver, consent or approval of any Governmental Entity which is necessary to permit Offeror to take up and pay for Common Shares deposited under the Offer, then, provided that such injunction or order is being contested or appealed or such waiver, consent or approval is being actively sought, as applicable, this Agreement shall not be terminated by Miramar pursuant to Section 7.1(e) until the fifth business day following the date on which such injunction or order ceases to be in effect or such waiver, consent or approval is obtained or six months from the date of mailing of the Offer, whichever occurs first;

(f) by Offeror if:

(i) any court of competent jurisdiction or other Governmental Entity shall have issued an order, decree or ruling enjoining or otherwise prohibiting any of the transactions contemplated in this Agreement (unless such order, decree or ruling has been withdrawn, reversed or otherwise made inapplicable); or

(ii) any litigation or other proceeding is pending or has been threatened to be instituted by any person or Governmental Entity, which, in the good faith judgment of Offeror, could reasonably be expected to result in a decision, order, decree or ruling which enjoins, prohibits, grants damages in a material amount in respect of, or materially impairs the benefits of, any of the Contemplated Transactions;

(g) by Offeror, if:

(i) Miramar is in default of any covenant or obligation in Section 6.2;

(ii) Miramar is in material default of any other covenant or obligation under this Agreement (without giving effect to, applying or taking into consideration any materiality qualification already contained in such covenant or obligation); or

(iii) any representation or warranty made by Miramar under this Agreement shall have been at the date hereof untrue or incorrect or, shall have become untrue or incorrect in any material respect at any time prior to the Expiry Time (without giving effect to, applying or taking into consideration any materiality or Material Adverse Effect qualification already contained within such representation or warranty),

- 29 -

and such default or inaccuracy in clauses (ii) or (iii) is not curable or, if curable, is not cured by the earlier of the date which is 15 days from the date of written notice of such breach and the Expiry Time;

(h) by Miramar, if any representation or warranty of Offeror under this Agreement is untrue or incorrect in any material respect at any time prior to the Expiry Time and such inaccuracy is reasonably likely to prevent, restrict or materially delay consummation of the Offer and is not curable or, if curable, is not cured by the earlier of the date which is 15 days from the date of written notice of such breach and the Expiry Time;

(i) by Miramar, if Offeror is in material default of any covenant or obligation under this Agreement;

(j) by Offeror, if:

(i) the Board of Directors fails to publicly reaffirm its approval of the Offer in accordance with Section 6.2(i);

(ii) the Board of Directors or any committee thereof withdraws, modifies, changes or qualifies its approval or recommendation of this Agreement or the Offer in any manner adverse to Offeror; or

(iii) the Board of Directors or any committee thereof recommends or approves or publicly proposes to recommend or approve an Acquisition Proposal; and

(k) by Miramar, if Miramar enters into a definitive agreement with respect to a Superior Proposal in compliance with the provisions of Section 6.2(g), provided that Miramar has previously or concurrently will have paid to Offeror the Termination Payment and further provided that Miramar has not breached in a material respect any of its covenants, agreements or obligations in this Agreement.

7.2 Termination and Expense Reimbursement Payments

(a) Offeror shall be entitled to a cash termination payment in the amount of $41.4 million (the “Termination Payment”), upon the occurrence of any of the following events (each a “Termination Payment Event”) which shall be paid by Miramar within the time specified in respect of each such Termination Payment Event:

(i) this Agreement is terminated pursuant to Section 7.1(j), in which case the Termination Payment shall be paid to Offeror or the Offeror Assignee no later than 1:00 p.m. (Toronto time) on the first business day following the occurrence of the action or inaction described therein;

(ii) this Agreement is terminated pursuant to Section 7.1(g)(i), in which case the Termination Payment shall be paid to Offeror or the Offeror Assignee no later than 1:00 p.m. (Toronto time) on the first business day following the occurrence of the action or inaction described therein;;

(iii) this Agreement is terminated pursuant to Section 7.1(k), in which case the Termination Payment shall be paid to Offeror or the Offeror Assignee in accordance with Section 6.2(g)(vi);

- 30 -

(iv) if it was publicly disclosed and was not formally withdrawn prior to the termination of the Offer, or involves a person with whom Miramar has entered into a confidentiality agreement after the date hereof and before the termination of the Offer, during the period commencing on the date hereof and ending 12 months following the termination of this Agreement (A) an Acquisition Proposal is consummated, or (B) the Board of Directors approves or recommends an Acquisition Proposal, or Miramar enters into a definitive agreement with respect to an Acquisition Proposal, in which case the Termination Payment shall be paid to Offeror or the Offeror Assignee on the earlier of the date the Acquisition Proposal is consummated and the date the Acquisition Proposal is approved or recommended or entered into or agreed to;

provided, in each case, that Offeror is not in material default in the performance of its obligations under this Agreement.

(b) Offeror shall be entitled to an expense reimbursement payment of $6.0 million (the “Expense Reimbursement Payment”) if the Agreement is terminated pursuant to Section 7.1(g)(ii) or 7.1(g)(iii).

(c) Upon written notice to Miramar, Offeror may assign its right to receive the Termination Payment or Expense Reimbursement Payment to any affiliate of Offeror (the “Offeror Assignee”).

(d) The Termination Payment and the Expense Reimbursement Payment shall be paid by Miramar to Offeror or the Offeror Assignee by wire transfer in immediately available funds to an account specified by Offeror. For greater certainty, the obligations of Miramar under this Section 7.2 shall survive the termination of this Agreement, regardless of the circumstances thereof.

(e) Miramar acknowledges that the amount set out in Section 7.2(a) in respect of the Termination Payment represents liquidated damages which are a genuine pre-estimate of the damages, including opportunity costs, which 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. Miramar irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive.

(f) For greater certainty, (i) Miramar shall not be obligated to pay the Termination Payment to Offeror or the Offeror Assignee more than once even if one or more of the events specified in Section 7.2(a) occurs and (ii) Miramar shall not be obligated to pay the Expense Reimbursement Payment to Offeror or the Offeror Assignee if the Termination Payment is paid.

7.3 Effect of Termination

For greater certainty, the parties agree that, where a Termination Payment Event occurs, the Termination Payment to be received pursuant to Section 7.2 is the sole remedy in compensation or damages of Offeror and the Offeror Assignee with respect to the event or events giving rise to the termination of this Agreement and the resulting Termination Payment Event; provided, however, that nothing contained in this Section 7.3, and no payment of any Termination Payment, shall relieve or have the effect of relieving any party in any way from liability for damages incurred or suffered by a party as a result of an intentional or wilful breach of this Agreement, including the intentional or wilful making of a

- 31 -

misrepresentation in this Agreement (including the Schedules hereto). Nothing in this Agreement shall preclude a party from seeking injunctive relief to restrain any breach or threatened breach of the covenants or agreements set forth in this Agreement or otherwise to obtain specific performance of any such covenants or agreements, without the necessity of posting bond or security in connection therewith.

7.4 Amendment

This Agreement may not be amended except by an instrument signed by each of the parties hereto.

7.5 Waiver

At any time prior to the termination of this Agreement pursuant to Section 7.1, any party hereto may: (a) extend the time for the performance of any of the obligations or other acts of any other party hereto; or (b) waive compliance with any of the agreements of the other party or with any conditions to its own obligations, in each case only to the extent such obligations, agreements and conditions are intended for its benefit.

ARTICLE 8

GENERAL PROVISIONS

8.1 Further Assurances

The parties shall with reasonable diligence do all such things and provide all such reasonable assurances as may be required to consummate the transactions contemplated by this Agreement, and each party shall provide such further documents or instruments required by any other party as may be reasonably necessary or desirable to effect the purpose of this Agreement and carry out its provisions.

8.2 Expenses

Subject to Section 7.2, the parties agree that all costs and expenses of the parties relating to the Offer and the Contemplated Transactions, including legal fees, accounting fees, financial advisory fees, regulatory filing fees, stock exchange fees, all disbursements of advisors and printing and mailing costs, shall be paid by the Party incurring such expenses.

8.3 Advisors

Offeror and Miramar represent and warrant to each other that, with the exception of Genuity Capital Markets, Citibank and XX Xxxxxx and their affiliates, for whose fees and expenses Offeror shall be solely liable, and the Financial Advisors and their affiliates, for whose fees and expenses Miramar shall be solely liable, no securityholder, director, officer, employee, consultant, broker, finder or investment banker is entitled to any brokerage, finder’s or other fee or commission, or to the reimbursement of any of its expenses, in connection with the Offer or any similar transaction based upon arrangements made by or on behalf of Offeror or Miramar, as the case may be.

8.4 Public Statements

Except as required by applicable Law or applicable stock exchange requirements, none of Offeror and Miramar shall make any public announcement or statement with respect to the Offer or this Agreement without the approval of the other parties, such approval not to be unreasonably withheld or

- 32 -

delayed. Moreover, in any event, each party agrees to give prior notice to the other of any public announcement relating to the Offer or this Agreement and agrees to consult with each other prior to issuing each such public announcement. Each of Offeror and Miramar agrees that, promptly after the entering into of this Agreement, the parties shall issue a joint press release announcing the entering into of this Agreement, which press release shall be satisfactory in form and substance to each of the parties, acting reasonably.

8.5 Confidentiality

All information of a confidential nature relating to a party or its business that is disclosed to the other party in accordance with this Agreement or in connection with the Offer and the Contemplated Transactions shall be held in confidence by the receiving party and shall not be disclosed to any person or the public except with the prior written consent of the disclosing party, acting reasonably. Such consent shall not apply to the disclosure of confidential information as required by applicable Law, provided that:

(a) only the confidential information that is legally required may be disclosed; and

(b) the party making such disclosure as required by applicable Law shall consult with the party who disclosed the confidential information in accordance with this Agreement or in connection with the Offer and the transactions contemplated in this Agreement and co-operate with such party who disclosed the confidential information to obtain a protective order or other remedy.

8.6 Remedies

Subject to Section 7.3, the parties acknowledge and agree that an award of money damages would be inadequate for any breach of this Agreement by any party or its representatives and any such breach would cause the non-breaching party irreparable harm.

Accordingly, the parties agree that, in the event of any breach or threatened breach of this Agreement by one of the parties, the non-breaching party will also be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance. Such remedies will not be the exclusive remedies for any breach of this Agreement but will be in addition to all other remedies available at law or equity to each of the parties.

8.7 Notices

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 the same or sending the same by facsimile transmission or by delivery addressed to the party to which the notice is to be given at its address for service in this Agreement. 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 in this Agreement (if a business day, if not, the next succeeding business day) 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 the next succeeding business day) unless actually received after 4:30 p.m. (Toronto time) at the point of delivery in which case it shall be deemed to have been given and received on the next business day.

(c) shall be governed in all respects, including validity, interpretation and effect, by the Laws of the Province of British Columbia and the federal Laws of Canada applicable therein, without giving effect to any principles of conflict of Laws thereof which would result in the application of the Laws of any other jurisdiction, and all actions and proceedings arising out of or relating to this Agreement shall be heard and determined exclusively in the courts of the Province of British Columbia.

8.10 Contra Proferentum

The parties waive the application of any rule of Law which otherwise would be applicable in connection with the construction of this Agreement that ambiguous or conflicting terms or provisions should be construed against the party who (or whose counsel) prepared the executed agreement or any earlier draft of the same.

8.11 No Third Party Beneficiaries

Except as provided in Section 2.3, which rights are hereby acknowledged and agreed to by Miramar, this Agreement is not intended to confer on any person other than the parties any rights or remedies.

SCHEDULE A

CONDITIONS OF THE OFFER

Notwithstanding any other provision of the Agreement to which this schedule is attached and subject to applicable Laws, Offeror will have the right to withdraw or terminate the Offer (or amend the Offer to postpone taking up and paying for any Common Shares deposited under the Offer), and shall not be required to accept for payment, take up, purchase or pay for, or extend the period of time during which the Offer is open and postpone taking up and paying for, any Common Shares deposited under the Offer, unless all of the following conditions are satisfied or waived by Offeror at or prior to the Expiry Time:
