2.2 Arizona Star Support for the Offer

(a) Arizona Star represents and warrants to and in favour of Barrick, and acknowledges that Barrick is relying upon such representations and warranties in entering into this Agreement, that as of the date hereof:

the Special Committee has received an opinion from its financial advisor, Citigroup Global Markets Inc., to the effect that, as of the date of such


		12

			opinion, the Offer Price to be received under the Offer by Shareholders (other than Barrick and its affiliates) is fair, from a financial point of view, to such Shareholders;

	(ii)		the Board of Directors, upon consultation with its financial and legal advisors and on receipt of a recommendation of the Special Committee, has unanimously determined that the Offer is in the best interests of Arizona Star and the Shareholders, and accordingly, has unanimously approved the entering into of this Agreement and the making of a recommendation that Shareholders (other than Barrick) accept the Offer;

	(iii)		each member of the Board of Directors has agreed to support the Offer and has agreed that the press release to be issued by Barrick announcing the Offer may so state and that references to such support may be made in the Circular and other documents relating to the Offer; and

	(iv)		the Board of Directors has by resolution deferred separation of the SRP Rights with respect to the Contemplated Transactions until a time to be determined by the Board of Directors (to be no earlier than immediately after the Expiry Time), and has irrevocably waived or suspended the operation of or otherwise rendered the Shareholder Rights Plan inoperative against the Offer and the acquisition of Common Shares pursuant thereto with effect as of thirty minutes prior to the scheduled expiry time (on the first scheduled expiry date of the Offer upon which Barrick elects to take up Common Shares deposited pursuant to the Offer.

(b) Arizona Star shall prepare and make available for distribution contemporaneously and together with the mailing of the Circular, in both the English and French languages as circumstances may require, sufficient commercial copies of the Directors’ Circular, prepared in all material respects in accordance with all Applicable Securities Laws and delivered in accordance with Section 2.1(h)(vi), which shall reflect the determinations and recommendation and agreement by the Board of Directors referred to in Section 2.2(a). Arizona Star shall take all reasonable actions to support the Offer and ensure the success of the Offer in accordance with this Agreement and Arizona Star shall provide Barrick with any information pertaining to Arizona Star and the Arizona Star Subsidiaries that is necessary or desirable for the completion of the Circular by Barrick, and shall provide Barrick with such other assistance in the preparation of the Circular as may be reasonably requested by Barrick. Notwithstanding the foregoing, if after the date hereof:

(i)

any representation or warranty made by Barrick in this Agreement shall be 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;


		13

	(ii)		the Board of Directors shall become aware of any untrue statement of a material fact, or an omission to state a material fact that is required to be stated or that is necessary to make a statement not misleading in light of the circumstances in which it was made, in the Circular or Directors’ Circular relating to Barrick; or

	(iii)		the Board of Directors is otherwise required in the exercise of its fiduciary duties to do so;

then the Board of Directors shall be entitled to not make such a positive recommendation, to make a negative recommendation or to withdraw, modify or change any recommendation regarding the Offer which it has previously made, provided that:

	(X)		the Board of Directors, acting in good faith and upon the advice of its legal advisors where appropriate, shall first have determined that the making of a positive recommendation, the failure to make a negative recommendation or the failure to withdraw, modify or change any recommendation regarding the Offer would be inconsistent with the fiduciary duties of the Board of Directors; and

	(Y)		not making such a positive recommendation, making a negative recommendation or so withdrawing, modifying or changing a recommendation regarding the Offer is otherwise in accordance with the terms of this Agreement.

(c) Arizona Star shall provide to Barrick all information regarding Arizona Star that is required for the preparation of the Circular. Arizona Star represents, warrants and covenants that such information will be true and correct in all material respects as at the date of the Circular and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

(d) Arizona Star hereby consents, pursuant to Section 10 of the Confidentiality Agreement, to the announcement of ▇▇▇▇▇▇▇’▇ intention to make the Offer, the making of the Offer and the consummation of the Contemplated Transactions.

	(ii)		it shall agree with Arizona Star to tendering arrangements in respect of the Offer in order to facilitate the conditional exercise of the Options and


		14

			tender to the Offer, concurrent with the first scheduled expiry time of the Offer in respect of which Barrick takes up Common Shares, of the Common Shares to be issued as a result of such conditional exercise (including providing for the ability of holders of Options to tender the Common Shares issuable upon such conditional exercise of their Options on the basis of guaranteed deliveries); and

	(iii)		(A) holders of Options will be permitted to tender Common Shares issuable upon the exercise thereof and for such purpose to exercise their Options, conditional upon Barrick taking up and paying for the Common Shares under the Offer, which Options shall be deemed to have been exercised concurrent with the first scheduled expiry time of the Offer in respect of which Barrick takes up Common Shares and (B) all Common Shares that are to be issued pursuant to any such conditional exercise shall be accepted as validly tendered under the Offer, provided that the holders of such Options indicate that the Common Shares are tendered pursuant to the Offer and otherwise validly accept the Offer in accordance with its terms with respect to such Shares.

2.4 Shareholder Rights Plan

(a) Without limiting Section 2.2(a)(iv), Arizona Star and the Board of Directors shall take all further action necessary:

	(i)		in order to ensure that the Separation Time (as defined in the Shareholder Rights Plan) does not occur in connection with this Agreement or any of the Contemplated Transactions;

	(ii)		otherwise to give effect to the waiver, if required, of the application of the Shareholder Rights Plan to the Contemplated Transactions and to ensure that the Shareholder Rights Plan does not interfere with or impede the success of any of the Contemplated Transactions; and

	(iii)		in order to ensure that upon the take-up of Common Shares pursuant to the Offer, all SRP Rights cease to be exercisable and are immediately redeemed at the “Redemption Price” as provided under the Shareholder Rights Plan without further formality and to ensure that upon such redemption all SRP Rights become null and void.

(b) Arizona Star covenants that (i) it will not waive the application of the Shareholder Rights Plan to any Acquisition Proposal unless it is a Superior Proposal and the Right to Match Period has expired and (ii) it will not amend the Shareholder Rights Plan nor authorize, approve or adopt any other shareholder rights plan or enter into any agreement providing therefor. Notwithstanding the foregoing, Arizona Star shall be entitled to defer the Separation Time in connection with an Acquisition Proposal.


		15

2.5 Officers and Employees

From and after the time at which persons designated by Barrick represent a majority of the Board of Directors, Barrick will cause Arizona Star and the Arizona Star Subsidiaries to comply with all of their respective obligations to the employees and officers of Arizona Star and the Arizona Star Subsidiaries pursuant to applicable Law.

2.6 Directors of Arizona Star

Arizona Star acknowledges that promptly following the time (the “Change in Control Time”) at which Barrick takes up for purchase such number of Common Shares as represents at least a majority of the then outstanding Common Shares on a fully-diluted basis and from time to time thereafter, Barrick shall be entitled to designate such number of members of the Board of Directors, and any committees thereof, as is proportionate to the percentage of the outstanding Common Shares beneficially owned from time to time by Barrick (the “Barrick Percentage”) and Arizona Star shall not frustrate ▇▇▇▇▇▇▇’▇ attempts to do so and covenants to co-operate with Barrick, subject to all applicable Laws, to enable ▇▇▇▇▇▇▇’▇ designees to be elected or appointed to the Board of Directors, and any committee thereof, and to constitute the Barrick Percentage of the Board of Directors, including, at the request of Barrick, by its commercially reasonable best efforts to increase the size of the Board of Directors and to secure the resignations of such directors as Barrick may request.

2.7 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 Barrick, or an “affiliate” or an “associate” (as those terms are defined in the BCBCA) of Barrick, Barrick 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 Barrick chooses not to avail itself of such statutory right of acquisition, Barrick shall use its commercially reasonable efforts to pursue other means of acquiring the remaining Common Shares not tendered to the Offer. Arizona Star agrees that, in the event Barrick takes up and pays for Common Shares under the Offer representing at least a simple majority of the outstanding Common Shares (calculated on a fully-diluted basis as at the Expiry Time), it will assist Barrick in connection with any proposed amalgamation, statutory arrangement, amendment to articles, consolidation, capital reorganization or other transaction involving Arizona Star and Barrick or a Barrick Subsidiary that Barrick 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 and provided that, in connection with a Subsequent Acquisition Transaction consummated within 120 days of the Expiry Time, if such value is greater than that paid to Shareholders pursuant to the Offer, the Shareholders who accepted the Offer will be “topped up” to be paid, when added to the consideration per Common Share paid pursuant to the Offer, the same value per Common Share as is received pursuant to such Subsequent Acquisition Transaction.


		16

2.8 Transaction Structuring and Alternative Transaction

(a) Barrick and Arizona Star 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 such step or action, to complete the Offer and the other transactions contemplated hereby as promptly as practicable.

(b) In addition, in the event that Barrick concludes that it is necessary or desirable to proceed with another form of transaction (such as a plan of arrangement or amalgamation) whereby Barrick or a Barrick Subsidiary 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 Arizona Star and its Shareholders that are equivalent to or better than those contemplated by this Agreement (an “Alternative Transaction”), Arizona Star 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.

(i)

make, solicit, assist, initiate, encourage or otherwise facilitate (including by way of furnishing non-public information, permitting any visit to any facilities or properties of Arizona Star or any Arizona Star Subsidiary, or entering into any form of written or oral agreement, arrangement or understanding) any inquiries, proposals or offers regarding (A) any merger, take-over bid, issuer bid, amalgamation, plan of arrangement, share exchange, business combination, consolidation, recapitalization, reorganization, liquidation, dissolution or winding-up in respect of Arizona Star or any Arizona Star Subsidiary; (B) any sale or acquisition of all or a material portion of the assets of Arizona Star or any Arizona Star Subsidiary; (C) any sale or acquisition of all or a material portion of the Common Shares or other securities of Arizona Star or of all or any of the securities of any Arizona Star Subsidiary; (D) any sale of an interest in any mineral property or joint venture; (E) any similar business combination or transaction of or involving Arizona Star or any of the Arizona Star Subsidiaries, including any joint venture, earn-in, farm-in or similar structure or arrangement, other than with Barrick or a Barrick Subsidiary; or (F) any proposal or offer to, or public announcement of an intention to do, any of the foregoing from any person other than Barrick or a Barrick Subsidiary (an “Acquisition Proposal”);

	(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:

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

	(Y)		engage in discussions or negotiations with, respond to enquiries from or provide information pursuant to Section 6.2(e) to, any person in response to an Acquisition Proposal made by any such person,

if and only to the extent that:

(A)

it has received an unsolicited bona fide written Acquisition Proposal from such person subsequent to the date hereof:

to purchase or otherwise acquire, directly or indirectly, by means of a merger, take-over bid, amalgamation, plan of arrangement, business combination or similar transaction, all of the Common Shares and pursuant to which all Shareholders are offered the same consideration in form and amount per Common Share to be purchased or otherwise acquired;

	2.		that did not result from a breach of this Section 6.2;

	3.		that complies with all Applicable Securities Laws;

	4.		in respect of which any required financing to complete such Acquisition Proposal has been demonstrated to the satisfaction of the Board of Directors, acting in good faith (after consultation with its financial advisors and outside legal counsel), will be obtained;

	5.		that is not subject to any due diligence and/or access condition which would allow access to the books, records, personnel or properties of Arizona Star or any Arizona Subsidiary or their respective representatives beyond 5:00 p.m. (Toronto time) on the fifth day after which access is first afforded to the third party making the Acquisition Proposal, provided that any such due diligence and/or access condition must be satisfied or waived at or before such time;

	6.		that the Board of Directors has determined in good faith (after consultation with its financial advisors and outside legal counsel) (x) is reasonably capable of completion without undue delay taking into account all legal, financial, regulatory and other aspects of such Acquisition Proposal and the person making such Acquisition Proposal, and (y) would, if consummated in accordance with its terms (but not assuming away any risk of non-completion), result in a transaction more favourable from a financial point of view to the Shareholders than the Offer (including any adjustment to the terms and conditions of the Offer proposed by Barrick pursuant to Section 6.2(h)); and

	7.		in respect of which the Board of Directors has determined in good faith (after receipt of advice from its outside legal counsel) that failure to recommend such Acquisition Proposal to Shareholders would be inconsistent with its fiduciary duties,

(any such Acquisition Proposal meeting all of the requirements of this Section 6.2(a)(A) being referred to herein as a “Superior Proposal”); and

(B)

in the case of Section 6.2(a)(X), Arizona Star shall have first complied with all of the requirements of Section 6.2(g).

(b) Arizona Star will immediately cease, and will instruct its financial advisors and other representatives and agents to cease, any existing solicitation, discussion or negotiation with any person (other than Barrick or a Barrick Subsidiary), by or on behalf of Arizona Star or any Arizona Star Subsidiary with respect to or which could lead to any potential Acquisition Proposal, whether or not initiated by Arizona Star or any Arizona Star Subsidiaries or any of its or their officers, directors, employees, representatives or agents, and, in connection therewith, Arizona Star will discontinue access to any data rooms (virtual or otherwise).

(c) Arizona Star 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 confidentially propose to the Board of Directors an unsolicited Acquisition Proposal meeting the criteria set out in Section 6.2(a)(A)1 that did not result from a breach of Section 6.2(a)), provided that this Section 6.2(c) shall not prevent the Board of Directors from considering and accepting any new Acquisition Proposal that is a Superior Proposal that might be made by any such third party, provided in each case that the remaining provisions of this Agreement are complied with. Within three business days from the date hereof, Arizona Star shall request the return or destruction of all information provided to any third parties who have entered into a confidentiality agreement with Arizona Star 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 and promptly (and in any event within 24 hours) provide copies of all correspondence relating to same to Barrick. Arizona Star will immediately advise Barrick orally and in writing of any response or action (actual, anticipated, contemplated or threatened) by any such third party which could reasonably be expected to hinder, prevent or delay or otherwise adversely affect the completion of the Offer.

(d) From and after the date of this Agreement, Arizona Star shall promptly (and in any event within 24 hours after it has received any proposal, inquiry, offer or request) notify Barrick, at first orally and then in writing, of any proposal, inquiry, offer or request (or any amendment thereto) relating to or constituting a bona fide Acquisition Proposal, any request for discussions or negotiations relating to, or which could lead to, an Acquisition Proposal, and/or any request for non-public information relating to Arizona Star or any Arizona Star Subsidiary or Arizona Star mineral property or contractual or legal rights or for access to properties, books and records or a list of the Shareholders of Arizona Star or Arizona Star Subsidiaries of which Arizona Star’s directors, officers, employees, representatives or agents are or become aware, or any amendments to the foregoing. Such notice shall include a description of the terms and conditions of, and the identity of the person making, any proposal, inquiry, offer or request, (including any amendment thereto) and shall include copies of any such proposal, inquiry, offer or request or any amendment to any of the foregoing. Arizona Star shall also provide such other details of the proposal, inquiry, offer or request, or any amendment to the foregoing, as Barrick may reasonably request. Arizona Star shall keep Barrick promptly and fully informed of the status, including any change to the material terms, of any such proposal, inquiry, offer or request, or any amendment to the foregoing, and will respond promptly to all inquiries by Barrick with respect thereto.

(e) If Arizona Star receives a request for non-public information from a person who, on an unsolicited basis, has proposed to Arizona Star a bona fide Acquisition Proposal and (x) the Board of Directors determines, in good faith, after consultation with its financial advisors and outside legal counsel, that such Acquisition Proposal would be, if consummated in accordance with its terms, reasonably likely to result in a Superior Proposal; and (y) in the opinion of the Board of Directors, acting in good faith and upon the advice of their outside legal advisors, the failure to provide such person with access to information regarding Arizona Star would be inconsistent with the fiduciary duties of the Board of Directors, then, and only in such case, Arizona Star may provide such person with access to information regarding Arizona Star, subject to the execution of a confidentiality agreement (the “Third Party Confidentiality Agreement”)

substantially in the form and on the terms of the Confidentiality Agreement, including for greater certainty, a standstill covenant on substantially the same terms as the standstill covenant contained in Section 10 of the Confidentiality Agreement, which standstill covenant in the Third Party Confidentiality Agreement shall have a duration of at least 12 months, and provided that the circumstances in which the standstill covenant in the Third Party Confidentiality Agreement shall be lifted shall not reflect the equivalent provisions of the Confidentiality Agreement but instead will be limited to allowing the party to the Third Party Confidentiality Agreement to confidentially propose to the Board of Directors an unsolicited Acquisition Proposal meeting the criteria set out in Section 6.2(a)(A)1 that did not result from breach of Section 6.2(a) and that is otherwise in compliance with this Agreement; and provided further that Arizona Star sends a copy of any such Third Party Confidentiality Agreement to Barrick promptly upon its execution and Barrick is provided with a list of or copies of the information provided to such person and is immediately provided with access to the same information which was provided by Arizona Star to such person.

(f) Arizona Star shall ensure that its officers, directors, employees, representatives and agents, and the Arizona Star Subsidiaries and their officers, directors, employees, representatives and agents, are aware of the provisions of this Section 6.2 and Arizona Star shall be responsible for any breach of this Section 6.2 by such officers, directors, employees, representatives or agents.

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

	(i)		the Acquisition Proposal constitutes a Superior Proposal;

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

	(iii)		Arizona Star has provided Barrick with notice in writing that there is a Superior Proposal, together with all documentation related to and detailing the Superior Proposal (including a copy of the confidentiality agreement between Arizona Star and the person making the Superior Proposal if not previously delivered and a written notice from the Board of Directors regarding the value in financial terms that the Board of Directors has in consultation with its financial advisors determined should be ascribed to any non-cash consideration offered under such Superior Proposal), at least five business days prior to the date on which the Board of Directors proposes to accept, approve, recommend or to enter into any agreement relating to such Superior Proposal;

	(iv)		five business days shall have elapsed (the “Right to Match Period”) from the date Barrick received the notice and documentation referred to in Section 6.2(g)(iii) from Arizona Star in respect of the Acquisition Proposal and, if Barrick has proposed to amend the terms of the Offer in accordance with Section 6.2(h), the Board of Directors shall have determined, in good faith, after consultation with its financial advisors and

outside legal counsel, that the Acquisition Proposal is a Superior Proposal compared to the proposed amendment to the terms of the Offer by Barrick;

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

	(vi)		Arizona Star has previously, or concurrently will have, paid to Barrick or the Barrick Assignee the Termination Payment.

(h) Arizona Star acknowledges and agrees that, 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 Arizona Star may approve for such purpose, Barrick shall have the opportunity, but not the obligation, to propose to amend the terms of this Agreement and the Offer and Arizona Star shall co-operate with Barrick with respect thereto, including negotiating in good faith with Barrick to enable Barrick to make such adjustments to the terms and conditions of this Agreement and the Offer as Barrick deems appropriate and as would enable Barrick to proceed with the Offer and any Contemplated Transactions on such adjusted terms. The Board of Directors will review any proposal by Barrick to amend the terms of the Offer in order to determine, in good faith in the exercise of its fiduciary duties and consistent with Section 6.2(a), whether ▇▇▇▇▇▇▇’▇ 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.

The Board of Directors shall promptly reaffirm its recommendation of the Offer by press release after: (x) any Acquisition Proposal which the Board of Directors determines not to be a Superior Proposal is publicly announced or made; or (y) the Board of Directors determines that a proposed amendment to the terms of the Offer would result in the Acquisition Proposal which has been publicly announced or made not being a Superior Proposal, and Barrick has so amended the terms of the Offer. Barrick and its counsel shall be given a reasonable opportunity to review and comment on the form and content of any such press release, recognizing that whether or not such comments are appropriate will be determined by Arizona Star, acting reasonably.

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. Further, nothing in this Agreement shall prevent the Board of Directors from making any disclosure to the securityholders of Arizona Star if the Board of Directors, acting in good faith and upon the advice of its legal advisors, shall have first determined that the failure to make such disclosure would be inconsistent with the fiduciary duties of the Board of Directors and provided further that such disclosure is otherwise in accordance with the terms of this Agreement. Barrick and its counsel shall be given a reasonable opportunity to review and comment on the form and content of any such directors’ circular, recognizing that whether or not such comments are appropriate will be determined by Arizona Star, acting reasonably.

(i) Arizona Star acknowledges and agrees that each successive modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for the purposes of Section 6.2.

6.3 Notification of Certain Matters

Each party shall give prompt notice to the others 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 (without giving effect to, applying or taking into consideration any materiality or Material Adverse Effect qualification already contained within such representation or warranty) in any material respect at any time from the date hereof to the Effective Time; and (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 Barrick

Upon reasonable notice, Arizona Star agrees to provide Barrick and its representatives with reasonable access (without disruption to the conduct of Arizona Star’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 material contracts, and access to the personnel of and counsel to Arizona Star and the Arizona Star Subsidiaries on an as reasonably requested basis as well as reasonable access to the properties of Arizona Star and the Arizona Star Subsidiaries in order to allow Barrick to conduct such investigations as Barrick may consider necessary or advisable to confirm the accuracy of Arizona Star’s representations and warranties herein, for strategic planning and integration, for the structuring of any Pre-Acquisition Reorganization and for any other reasons reasonably relating to the Contemplated Transactions, and further agrees to assist Barrick in all reasonable ways in any such due diligence investigations which Barrick may wish to conduct. Nothing in the foregoing shall require Arizona Star to disclose information which it is prohibited from disclosing pursuant to a written confidentiality agreement or confidentiality provision of an agreement with a third party or to provide Barrick with access to any property where Arizona Star is contractually or legally prohibited from doing so. Any such investigation by Barrick and its advisors shall not mitigate, diminish or affect the representations and warranties of the other party contained in this Agreement or any document or certificate given pursuant hereto.

6.5 Officers’ and Directors’ Indemnification

From and after the Effective Time, Barrick agrees that for the period from the Effective Time until six years after the Effective Time, Barrick will cause Arizona Star or any successor to Arizona Star to maintain Arizona Star’s current directors’ and officers’ liability insurance policy or a policy reasonably equivalent subject in either case to terms and conditions no less advantageous to the directors and officers of Arizona Star than those contained in the policy in effect on the date hereof, for all present and former directors and officers of Arizona Star and the Arizona Star Subsidiaries covering claims made prior to or within six years of the Effective Time, provided, however, that Barrick 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 policy; 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, Barrick 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. Alternatively, after the Effective Time, Barrick may, or may cause Arizona Star to, purchase as an extension to Arizona Star’s current directors’ and officers’ liability insurance policies run-off insurance providing such coverage for such persons on terms comparable to those contained in Arizona Star’s current insurance policies, provided that the premium will not exceed 200% of the premium currently charged to Arizona Star for directors’ and officers’ liability insurance, and in such event none of Barrick or Arizona Star or any Arizona Star Subsidiaries will have any further obligation under this Section 6.5.

6.6 Shareholder Claims

Arizona Star shall notify Barrick of any claim brought by (or threatened to be brought by) any present, former or purported holder of any securities of Arizona Star in connection with any of the Contemplated Transactions prior to the Effective Time. Arizona Star shall consult with Barrick prior to 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 Time without the prior written consent of Barrick.

6.7 Required Securities Laws Approvals

Barrick 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 Barrick to make the Offer and perform ▇▇▇▇▇▇▇’▇ other obligations hereunder, and Arizona Star shall co-operate in good faith in connection with any such action by Barrick.

6.8 Reorganization

Arizona Star agrees that, upon request by Barrick, Arizona Star shall (i) effect such reorganizations of its business, operations and assets or such other transactions as Barrick may request, acting reasonably (each a “Pre-Acquisition Reorganization”) and (ii) co-operate with Barrick 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 are not prejudicial to Arizona Star in any material respect and (A) do not result in any material breach by Arizona Star of (i) any existing contract or commitment of Arizona Star; or (ii) any Law; or (B) would not reasonably be expected to impede or delay ▇▇▇▇▇▇▇’▇ ability to take up and pay for the Arizona Star Shares tendered to the Offer. Barrick shall provide written notice to Arizona Star of any proposed Pre-Acquisition Reorganization at least ten business days prior to the Expiry Time. Upon receipt of such notice, Barrick and Arizona Star shall work co-operatively 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. Barrick agrees to waive any breach of a representation, warranty or covenant by Arizona Star where such breach is a result of an action taken by Arizona Star in good faith pursuant to a request by Barrick in accordance with this Section 6.8. The completion of any such Pre-Acquisition Reorganization shall be subject to the satisfaction of the Minimum Tender Condition and the satisfaction or waiver by Barrick of the other conditions to the Offer set forth in Schedule A and shall be effected immediately prior to any take-up by Barrick of Common

Shares tendered to the Offer. If Barrick does not take up and pay for the Common Shares tendered to the Offer, Barrick shall indemnify Arizona Star for all losses and reasonable out-of-pocket costs and expenses, including reasonable out-of-pocket legal fees and disbursements, incurred in connection with any proposed Pre-Acquisition Reorganization.

	(j)		by Barrick, if:

	(i)		the Board of Directors or any committee thereof fails to publicly recommend or reaffirm its approval of the Offer within two calendar days of any written request by Barrick (or, in the event that the Offer shall be scheduled to expire within such two calendar day period, prior to the scheduled expiry of the Offer);

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

7.2 Termination Payment

(a) Barrick shall be entitled to a cash termination payment (the “Termination Payment”) in an amount equal to $27,000,000, upon the occurrence of any of the following events (each a “Termination Payment Event”), which shall be paid by Arizona Star within the time specified in respect of each such Termination Payment Event:

	(i)		this Agreement is terminated pursuant to Section 7.1(f)(i) or pursuant to Section 7.1(j), in which case the Termination Payment shall be paid to Barrick or the Barrick Assignee by 4:00 p.m. (Toronto time) on the day on which this Agreement is so terminated;

	(ii)		this Agreement is terminated pursuant to Section 7.1(k), in which case the Termination Payment shall be paid to Barrick or the Barrick Assignee prior to or concurrently with the entering into of the definitive agreement referred to therein; or

	(iii)		on or after the date hereof and prior to the later of the Expiry Time and the date on which this Agreement is terminated, an Acquisition Proposal is publicly announced or made or any person has publicly announced an intention to make such Acquisition Proposal, and such Acquisition Proposal either has been accepted, recommended or approved by the Board of Directors or has not expired, been withdrawn or been publicly abandoned, and (A) the Offer is not completed as a result of the Minimum Tender Condition not having been met, and (B) any person or company acquires, directly or indirectly, more than 50% of the issued and outstanding Common Shares or more than 50% of the consolidated assets of Arizona Star, in each case within 12 months of the date of this Agreement, in which case the Termination Payment shall be paid to Barrick or the Barrick Assignee on the earlier of the date that an Acquisition Proposal is accepted, recommended or approved by the Board of Directors or concurrently with such acquisition of such Common Shares or assets.

(b) If Arizona Star does not have sufficient financial resources to pay the Termination Payment, then it shall be a condition of (i) any Superior Proposal referred to in Section 7.1(k) and (ii) any share or asset acquisition referred to in Section 7.2(a)(iii) where Arizona Star or its affiliate has entered into any agreement to support such share acquisition or to transfer such assets, as applicable, that the person making such Superior Proposal or acquisition, as applicable, shall advance or otherwise provide to Arizona Star the cash required for Arizona Star to pay the Termination Payment, which amount shall be so advanced or provided prior to the date on which Arizona Star is required to pay the Termination Payment.

(c) Upon written notice to Arizona Star, Barrick may assign its right to receive the Termination Payment to any Barrick Subsidiary (the “Barrick Assignee”).

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

(e) Arizona Star acknowledges that the amount set out in Section 7.2 in respect of the Termination Payment represents liquidated damages which are a genuine pre-estimate of the damages, including opportunity costs, which Barrick 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. Arizona Star 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, Arizona Star shall not be obligated to make more than one payment under Section 7.2 if one or more of the events specified therein occurs.

7.3 Effect of Termination Payment

For greater certainty, the parties agree that the Termination Payment to be received pursuant to Section 7.2 is the sole remedy in compensation or damages of the party receiving such Termination Payment with respect to the 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 misrepresentation in this Agreement (including the Schedules hereto). Nothing herein 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.
