principal executive officer and principal financial officer, or under their supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP. Since the date of the latest audited consolidated financial statements included in the Public Record, there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of a date within 90 days prior to the filing date of the Form 10-K for the fiscal year most recently ended (such date, the “Evaluation Date”). The Company presented in its Form 10-K for the financial year most recently ended the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date and the disclosure controls and procedures are effective. Since the Evaluation Date, there have been no significant changes in the Company’s internal controls (as such term is defined in Item 307(b) of Regulation S-K under the Act) or, to the Company’s knowledge, in other factors that could significantly affect the Company’s internal controls.

(z) In the ordinary course of its business, the Company periodically reviews the effect of Environmental Laws on the business, operations and properties of the Company and its Subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities of the Company and its Subsidiaries. On the basis of such review, the Company has reasonably concluded that such associated costs and liabilities would not, singly or in the aggregate, have a Material Adverse Effect, except as set forth in the Public Record.

To the Company’s knowledge, it is in compliance with all applicable listing requirements of the NYSE and the TSX.

(nn) Except pursuant to this Agreement, neither the Company nor any of its Subsidiaries has incurred any liability for any finder’s or broker’s fee, agent’s commission or similar payments in connection with the execution and delivery of this Agreement or the consummation of the transactions contemplated hereby.

(pp) Neither the Company nor any of its Subsidiaries, nor any of their respective directors, officers, nor, to the Company’s knowledge, any of their respective affiliate or controlling persons, have taken, directly or indirectly, without giving effect to activities of the Underwriters, any action designed to or that would reasonably be expected to cause or result in stabilization or manipulation of the price of the Shares or of any “reference security” (as defined in Rule 100 of Regulation M under the Exchange Act (“Regulation M”)) with respect to the Company’s Common Stock, whether to facilitate the sale or resale of the Shares, or otherwise, and has taken no action which would directly or indirectly violate Regulation M.

(uu) The Company has not entered into any agreements or made any covenants with any parties with respect to the renunciation of CEE, which amounts have not been fully expended and renounced as required under such agreements or covenants.

(vv) The Company has not entered into any agreements or made any covenants with any parties that would restrict the Company from entering into the Subscription Agreement and agreeing to incur and renounce Resource Expenses during the Expenditure Period in accordance with the Subscription Agreements, nor that would require the prior renunciation to any other person of Resource Expenses prior to the renunciation of the aggregate amount paid for the Shares in favour of the Purchasers.

(ww) The issuance and sale by the Company of the Shares to the Purchasers in accordance with the terms of this Agreement are exempt from the prospectus requirements of applicable Canadian Securities Laws and U.S. securities laws and no documents are required to be filed, proceedings taken or approvals, permits, consents or authorizations obtained under the applicable Canadian Securities Laws or applicable U.S. securities laws to permit such issuance and sale other than as otherwise provided in this Agreement, including the requirement to file a report on Form 45-106F1 and/or Form 45-106F6 pursuant to National Instrument 45-106, together with the prescribed filing fee, within 10 days following the Closing Date.

(yy) Neither the Company, any Subsidiary, nor any of the Company’s or any Subsidiary’s affiliates or any other person acting on the Company’s or any Subsidiary’s behalf, has directly or indirectly engaged in any form of general solicitation or general advertising with respect to the Shares, nor have any of such persons made any offers or sales of any security of the Company, any Subsidiary or any of the Company’s or any Subsidiary’s affiliates or solicited any offers to buy any security of the Company, any Subsidiary or any of the Company’s or any Subsidiary’s affiliates under circumstances that would require registration of the Shares under the Act or any other applicable U.S. securities laws or cause this offering of Shares to be integrated with any prior offering of securities of the Company or any Subsidiary for purposes of the Act in any manner that would affect the validity of the private placement exemption under the Securities Act for the offer and sale of the Shares hereunder.

(zz) Neither the Company nor its Subsidiaries or any affiliates, nor any person acting on its or their behalf, has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under any circumstances that would require registration of the Shares under the Act.

(aaa) Assuming the accuracy of the representations and warranties of the Purchasers contained in the Subscription Agreements, the issuance of the Shares are exempt from registration under the Act.

Any certificate signed by any officer of the Company and delivered to the Underwriters in connection with the offering of the Shares shall be deemed to be a representation and warranty by the Company, as to matters covered thereby, to each Underwriter.

The Company has a reasonable basis for making each of the representations set forth in this Section 1. The Company acknowledges that the Underwriters and, for purposes of the opinions to be delivered pursuant to Section 6 hereof, counsel to the Company, will rely upon the accuracy and truthfulness of the foregoing representations and hereby consents to such reliance.

(c) The Company and the Underwriters do not act, and will not purport to act, as agent or representative of the other in connection with any Follow-On Transaction and services

or activities, if any, performed by the Company or the Underwriters in connection with any Follow-On Transaction are excluded from this Agreement. The consideration payable to the Underwriters hereunder is for the Underwriter’s services in respect of the Offering only. The parties further acknowledge that the Company is not entitled, and will not become entitled, to receive any consideration in respect of any Follow-On Transaction that might occur.

(d) Without limiting any indemnification obligations contained herein, neither the Company or the Underwriters shall be liable or responsible for any breach of any covenant or representation given in this Agreement if the Shares are “prescribed shares” under subsection 6202.1(1) of the regulations to the Tax Act as a result of the Follow-On Transactions.

2. Purchase and Sale.

The Subscription Price per Share to be paid by the Underwriters to the Company shall be $3.22; and

(b) In consideration of the services to be rendered by the Underwriters in connection with the offering of the Shares, the Company shall pay the Underwriters a cash commission equal to 4.0% of the aggregate gross proceeds of the sale of the Shares, including, for greater certainty, any Shares sold directly to Substituted Purchasers.

Delivery of the Shares shall be made either through one or more physical certificates or through the facilities of The Depository Trust Company unless the Lead Manager shall otherwise instruct.

4. The Offering.

The Underwriters shall offer for sale and sell the Shares in accordance with the terms of this

Agreement, on a private placement basis pursuant to exemptions from the prospectus requirements of Canadian Securities Laws and Regulation S under the Act.

5. Agreements.

The Company agrees with the Underwriters that:

(a) it hereby agrees to incur (or be deemed to incur) Resource Expenses in an amount equal to the Commitment Amount on or before December 31, 2018 in accordance with the Subscription Agreements in respect of the Shares and agrees to renounce to the Purchasers, with an effective date no later than December 31, 2017, pursuant to subsections 66(12.6) and 66(12.66) of the Tax Act, Resource Expenses in an amount equal to the Commitment Amount;

The Company shall not, without the prior written consent of the Underwriters, enter into any other agreement which would prevent or restrict its ability to renounce Resource Expenses to the Purchasers in the amount of the Commitment Amount. If the Company is required under the Tax Act to reduce Resource Expenses previously renounced to a Purchaser, such renunciation shall be made pro-rata by the number of Shares issued to each Purchaser on the Closing Date and shall not reduce Resource Expenses renounced to any Purchaser until it has first reduced to the extent possible all CEE renounced to persons under subscription and renunciation agreements for flow-through shares entered into after the Closing Date. Such reduction shall be without any prejudice to any other rights the Purchasers or the Underwriters may have under this Agreement or the Subscription Agreements;

(e) the expenses to be renounced by the Company to the Purchaser:

(i) will constitute Resource Expenses on the effective date of renunciation;

(ii) will not include the amount of any assistance described in paragraph 66(12.6)(a), expenses that are “Canadian exploration and development overhead expenses” (as defined in the regulations to the Tax Act for purposes of paragraph 66(12.6)(b) of the Tax Act) of the Company, amounts which constitute specified expenses for seismic data described in paragraph 66(12.6)(b.1) of the Tax Act or any expenses for prepaid services or rent that do not qualify as outlays and expenses for the period as described in the definition of “expense” in subsection 66(15) of the Tax Act;

(iii) will not include any amount that has previously been renounced by the Company to the Purchaser or any other person;

(iv) would be deductible by the Company in computing its income for the purposes of Part I of the Tax Act but for the renunciation to the Purchaser; and

(v) will not be subject to any reduction under subsection 66(12.73) of the Tax Act;

(f) it will not be subject to the provisions of subsection 66(12.67) of the Tax Act in a manner which impairs its ability to renounce Resource Expenses to the Purchasers in an amount

(g) if it receives, or becomes entitled to receive, any government assistance which is described in paragraph 66(12.6)(a) of the Tax Act and the receipt or entitlement to receive such government assistance has or will have the effect of reducing the amount of CEE validly renounced to the Purchasers to less than the Commitment Amount, the Company shall incur additional CEE so that it may renounce Resource Expenses in an amount not less than the Commitment Amount, and failing which the Company shall remit to the Purchasers the benefit of all amounts received or receivable in respect of such government assistance to the extent of such reduction;

(h) it shall use the aggregate Commitment Amount received under all of the Subscription Agreements solely to incur “Canadian exploration expenses” (as defined in subsection 66.1(6) of the Tax Act) on the Company’s directly held mineral properties in Ontario, and in that regard shall have, prior to the Closing Date, entered into all farm-in or other agreements as are necessary to obtain a working interest in properties upon which such expenditures are made;

(k) if it does not renounce to the Purchasers, effective on or before December 31, 2017, Resource Expenses equal to the Commitment Amount, and provided that the particular Purchaser is not in breach of any of its representations, warranties or covenants which would prevent the renunciation of such expenses, the Company shall indemnify and hold harmless the Purchaser and each of the partners thereof if the Purchaser is a partnership or a limited partnership (for the purposes of this paragraph, each an “Indemnified Person”) as to, and pay in settlement thereof to the Indemnified Person within 20 days of such failure to renounce, an amount equal to the amount of any tax (within the meaning of “excluded obligation” in paragraph 6202.1(5)(c) of the regulations to the Tax Act) payable under the Tax Act (and under any corresponding provincial legislation) by any Indemnified Person as a consequence of such failure. If the amount renounced to a Purchaser under a Subscription Agreement is reduced pursuant to subsection 66(12.73) of the Tax Act, the Company shall indemnify and hold harmless each Indemnified Person as to, and pay in settlement thereof to, the Indemnified Person within 20 days of the date such amount is determined, an amount equal to the amount of any tax (within the meaning of “excluded obligation” in paragraph 6202.1(5)(c) of the regulations to the Tax Act) payable under the Tax Act (and under any corresponding provincial legislation) by the Indemnified Person as a consequence of such reduction. For certainty, the foregoing indemnity shall have no force or effect to the extent that such indemnity would otherwise cause the Shares to be “prescribed shares” within the meaning of section 6202.1 of the regulations to the Tax Act;

(l) it shall file with the CRA within the time prescribed by subsection 66(12.68) of the Tax Act, the forms prescribed for the purposes of such legislation together with a copy of the Subscription Agreement or any “selling instrument” contemplated by such legislation or by this Agreement, necessary to effectively renounce Resource Expenses equal to the Commitment Amount and shall forthwith following such filings provide to the Purchasers and the Underwriter a copy of such forms certified by two officers of the Company;

(m) it will maintain proper, complete and accurate accounting books and records relating to the Resource Expenses. The Company will retain all such books and records as may be required to support the renunciation of Resource Expenses contemplated by the Subscription Agreement;

(n) it shall not enter into any other agreement which would prevent or restrict its ability to renounce Resource Expenses to the Purchasers in the amount of the Commitment Amount;

(o) it shall perform and carry out all acts and things to be completed by it as provided in the Subscription Agreements;

(p) if it amalgamates with any one or more companies, any shares issued to or held by the Purchasers as a replacement for the Shares as a result of such amalgamation will qualify, by virtue of subsection 87(4.4) of the Tax Act, as “flow through shares” and in particular will not be “prescribed shares” as defined in Section 6202.1 of the regulations to the Tax Act;

(q) it will not knowingly renounce any Resource Expense to any trust, corporation or partnership with which the Company has a “prohibited relationship” as defined in subsection 66(12.671) of the Tax Act;

(r) it will use its commercially reasonable efforts to list the Shares on the NYSE and the TSX, and during the period hereof until the date eighteen months from the date hereof, maintain the listing of the Common Stock, including the Shares listed on the NYSE, the TSX or another national stock exchange, and maintain its status as a “reporting issuer” under the applicable Canadian Securities Laws under which it currently is a reporting issuer (or the equivalent) in the Canadian Jurisdictions and Québec;

(s) it will not without the prior written consent of the Lead Manager (such consent not to be unreasonably withheld), issue, offer, sell, contract to sell, pledge, or otherwise dispose of or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any affiliate of the Company, directly or indirectly, including the filing (or participation in the filing) of a registration statement or prospectus with the Commission or any Canadian Regulator or the Autorite des marches financiers in Quebec in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, with respect to any other shares of Common Stock or any securities convertible into, or exercisable or exchangeable for, such Common Stock, or publicly announce an intention to effect any such transaction, for a

period of 90 days after the date of this Agreement, except that the Company may (i) file any registration statement on Form S-8 designed to register or replace any equity plan or arrangement described in the Public Record, (ii) issue and sell Common Stock or grant performance shares, stock appreciation rights, options or other equity-based awards pursuant to any employee stock option plan, stock ownership plan or dividend reinvestment plan of the Company in effect at the date of this Agreement and disclosed in the Public Record, (iii) issue Common Stock issuable upon the conversion of securities or the exercise of warrants or options outstanding at the date of this Agreement and disclosed in the Public Record, or (iv) issue Common Stock to a seller in connection with the acquisition by the Company of mineral properties or other entities engaged in the mining business (including, without limitation, pursuant to an option agreement, joint venture or asset purchase), provided that the aggregate number of shares of Common Stock issued in connection with such transactions shall not exceed 10% of the number of shares of Common Stock outstanding as of the Closing Date; provided, however, that, except in the circumstance of an unsolicited bid, any such securities issued may not be subsequently disposed of until 90 days after the date of this Agreement by any recipient of such shares who, subsequent to such transaction, beneficially owns more than 1% of the Common Stock outstanding as of the Closing Date.

(t) it will execute and file with the Canadian Regulators, the Commission, the TSX and the NYSE all forms, notices and certificates required to be filed by the Company pursuant to Canadian Securities Laws, U.S. securities laws, and the policies of the TSX and the NYSE in the time required, including, for greater certainty, Form 45-106F1 and Form 45-106F6, as applicable, of National Instrument 45-106.

The documents required to be delivered by this Section 6 shall be delivered at the office of Borden Ladner Gervais LLP, Canadian counsel for the Underwriters, at 3400 East Tower, Bay Adelaide Centre, 22 Adelaide Street West, Toronto, Ontario, M5H 4E3, on the Closing Date.

7. Reimbursement of Underwriters’ Expenses. Whether or not the transactions contemplated herein shall be completed, the Company shall reimburse the Underwriters on demand for all documented out-of-pocket costs and expenses (including reasonable fees of U.S. and Canadian legal counsel in an amount not to exceed US$40,000, excluding taxes and disbursements) that

shall have been incurred by them in connection with the proposed purchase and sale of the Shares.

8. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless the Underwriters to the fullest extent permitted by law, from and against any and all losses, claims, damages, obligations, penalties, judgments, awards, and other liabilities (collectively, “Liabilities”), and will fully reimburse the Underwriters for any and all fees, costs, expenses and disbursements (collectively, “Expenses”), as and when incurred, of investigating, preparing or defending any claim, action, suit, proceeding or investigation, whether or not in connection with pending or threatened litigation or arbitration, and whether or not any Underwriter is a party (collectively, “Actions”) (including any and all legal and other Expenses in giving testimony or furnishing documents in response to a subpoena or otherwise), arising out of or in connection with advice or services rendered or to be rendered by any Underwriter pursuant to this Agreement, the transactions contemplated thereby or any Underwriter’s actions or inactions in connection with any such advice, services or transactions; provided, however, such indemnity agreement shall not apply to any portion of any such Liability or Expense that is found in a final judgment by a court of competent jurisdiction (not subject to further appeal) to have resulted primarily and directly from the gross negligence or willful misconduct of CFCC.

(b) The indemnification provisions in this section 8 shall be in addition to any liability which the Company may otherwise have and shall extend to the respective affiliated entities, directors, officers, employees and controlling persons (within the meaning of Canadian securities laws) of each of the Underwriters.

(c) If any Action is commenced as to which any Underwriter proposes to demand indemnification hereunder, it shall notify the Company with reasonable promptness; provided, however, that any failure by an Underwriter to notify the Company shall not relieve the Company from its obligations hereunder. The Underwriters shall have the right to retain counsel of their own choice to represent them collectively, and the Company shall pay the Expenses of such counsel; and such counsel shall, to the extent consistent with its professional responsibilities, cooperate with the Company and any counsel designated by the Company. The Company shall be liable for any settlement of any claim against an Underwriter made with the Company’s written consent, which consent shall not be unreasonably withheld. The Company shall not, without the prior written consent of CFCC, settle or compromise any claim, or permit a default or consent to the entry of any judgment, in any Action in respect of which indemnification may be sought hereunder.

(d) In order to provide for just and equitable contribution, if a claim for indemnification pursuant to the indemnification provisions in this section 8 is made but it is found in a final judgment by a court of competent jurisdiction (not subject to further appeal) that such indemnification may not be enforced in such case, even though the express provisions hereof provide for indemnification in such case, then the Company, on the one hand, and the Underwriters, on the other hand, shall contribute to the Liabilities and Expenses to which the indemnified persons may be subject in accordance with the relative benefits received by the

Company, on the one hand, and the Underwriters, on the other hand, and also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements, acts or omissions which resulted in such Liabilities and Expenses.

(e) The Company agrees for purposes of paragraph (d) that the relative benefits to the Company and the Underwriters of any contemplated Offering (whether or not consummated) shall be deemed to be in the same proportion as the total value paid or issued or contemplated to be paid or issued to or by the Company or its security holders or subsidiaries in connection with such Offering bears to the fees paid or payable to the Underwriters under this Agreement. Notwithstanding the foregoing, no Underwriter shall be obligated to contribute any amount pursuant to this section 8 that exceeds the amount of fees previously received by such Underwriter pursuant to this Agreement.

9. Default by an Underwriter.

(a) If any Underwriter or Underwriters shall default in its or their obligation to purchase Shares hereunder, and if the Shares with respect to which such default relates (the “Default Securities”) do not (after giving effect to arrangements, if any, made by the Lead Manager pursuant to subsection (b) below) exceed in the aggregate 10% of the number of Shares, each non-defaulting Underwriter, acting severally and not jointly, agrees to purchase from the Company that number of Default Securities that bears the same proportion of the total number of Default Securities then being purchased as the number of Shares set forth opposite the name of such non-defaulting Underwriter in Schedule I hereto bears to the aggregate number of Shares set forth opposite the names of the non-defaulting Underwriters, subject, however, to such adjustments to eliminate fractional Shares as the Lead Manager in its sole discretion shall make.

(b) In the event that the aggregate number of Default Securities exceeds 10% of the number of Shares, the Lead Manager may in its discretion arrange for itself or for another party or parties (including any non-defaulting Underwriter or Underwriters who so agree) to purchase the Default Securities on the terms contained herein. In the event that within five calendar days after such a default the Lead Manager does not arrange for the purchase of the Default Securities as provided in this Section 9, this Agreement shall thereupon terminate, without liability on the part of the Company with respect thereto (except in each case as provided in Sections 8 and 11) or the non-defaulting Underwriters, but nothing in this Agreement shall relieve a defaulting Underwriter or Underwriters of its or their liability, if any, to the other Underwriters and the Company for damages occasioned by its or their default hereunder.

(c) In the event that any Default Securities are to be purchased by the non-defaulting Underwriters, or are to be purchased by another party or parties as aforesaid, the Lead Manager or the Company shall have the right to postpone the Closing Date for a period, not exceeding five Business Days, in order to effect whatever changes may thereby be made necessary in any documents and arrangements. The term “Underwriter” as used in this Agreement shall include any party substituted under this Section 9 with like effect as if it had originally been a party to this Agreement with respect to such Shares.

10. Termination.

(a) This Agreement shall be subject to termination in the absolute discretion of the Lead Manager, by notice given to the Company prior to delivery of and payment for the Shares, if at any time prior to such time (a) trading or quotation in any of the Company’s Common Stock shall have been suspended or limited by the Commission, the NYSE or the TSX or trading in securities generally on the NYSE or the TSX shall have been suspended or limited or minimum prices shall have been established on such exchange, (b) a general banking moratorium shall have been declared by Canadian or U.S. federal, New York State or Ontario provincial authorities, (c) there shall have occurred any outbreak or escalation of national or international hostilities, or a declaration by the U.S. or Canada of a national emergency or war, major terrorist attack in a world commercial financial center, or other calamity or crisis, including a health epidemic, the effect of which on financial markets is such as to make it, in the sole judgment of the Lead Manager, impracticable or inadvisable to proceed with the Offering or delivery of the Shares as contemplated herein, (d) in the judgment of the Lead Manager there shall have occurred any Material Adverse Effect, or (e) the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Lead Manager may interfere materially with the conduct of the business and operations of the Company regardless of whether or not such loss shall have been insured.

(b) The rights of termination contained in Section 10(a) may be exercised by the Lead Manager and are in addition to any other rights or remedies any of the Underwriters may have in respect of any default, act or failure to act or non-compliance by the Company in respect of any of the matters contemplated by this Agreement or otherwise. In the event of any such termination, there shall be no further liability on the part of the Underwriters to the Company or on the part of the Company to the Underwriters, except that the Company shall be obligated to reimburse the expenses of the Underwriters and except in respect of any liability which may have arisen prior to or arise after such termination under Sections 8 and 14.

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers or its directors and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of the affiliates, officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Shares.
