Ladies and Gentlemen:

Lone Pine Resources Inc., a Delaware corporation (the “Company”) and a wholly-owned subsidiary of Forest Oil Corporation, a New York corporation (“Forest”), proposes to issue and sell to the several persons listed in Schedule 1 hereto as a “Canadian Underwriter” or a “U.S. Underwriter” (collectively, the “Underwriters”), for whom you are acting as representative (the “Representative”), an aggregate of 15,000,000 shares (the “Firm Securities”) of common stock, par value $0.01 per share (the “Common Stock”), of the Company.  In addition, the Company proposes to issue and sell to the Underwriters, at the option of the Underwriters, up to an additional 2,250,000 shares of Common Stock solely to cover over-allotments (the “Optional Securities”).  The Firm Securities and the Optional Securities are herein referred to as the “Securities.” The shares of Common Stock to be outstanding after giving effect to the sale of the Securities are referred to herein as the “Stock.”  The Stock, including the Securities, will have attached thereto rights (the “Rights”) to purchase one preferred share of the Company.

Prior to the Company’s offering of the Securities, Forest will obtain a private letter ruling from the U.S. Internal Revenue Service and/or an opinion of its outside tax advisor, in either case reasonably acceptable to the Forest board of directors, to the effect that the contribution by Forest of its direct and indirect ownership interests in CFOL and the Wiser Entities to the Company and the distribution by Forest of the shares of the Common Stock of the Company held by Forest after the Offering should qualify for U.S. federal income tax purposes as a tax-free transaction under Sections 355 and 368(a)(1)(D) of the U.S. Internal Revenue Code of 1986, as amended.

In addition, immediately prior to the Company’s offering of the Securities, Forest will contribute its direct ownership interests in Canadian Forest Oil Ltd., an Alberta corporation (“CFOL”), and its direct and indirect ownership interests in Wiser Oil Delaware, LLC, a Delaware limited liability company, and Wiser Delaware, LLC, a Delaware limited liability company (collectively, the “Wiser Entities”), to the Company. Subsequent to the Company’s offering of the Securities, Forest intends to distribute its remaining equity in the Company to

Forest’s shareholders as described in the U.S. Prospectus (as defined herein) (the “Spin-off”).  In connection with this offering and the Spin-off, the Company will enter into the agreements listed in Schedule 2 hereto with Forest prior to the completion of this offering relating to the separation of its business operations from Forest.  The agreements listed in Schedule 2 are collectively referred to herein as the “Transaction Documents.”

The Company hereby confirms its agreement with the several Underwriters concerning the purchase and sale of the Securities, as follows:

1.                                       U.S. Registration Statement and Canadian Prospectus.

(a)                                  The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the United States Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form S-1 (File No. 333-171123), including a prospectus, relating to the Securities and Rights.  Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary U.S. Prospectus” means the preliminary prospectus included in Amendment No. 6 to the registration statement on Form S-1 (File No. 333-171123) filed with the Commission under the Securities Act on May 11, 2011 and the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, and the term “U.S. Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Securities.  If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement.  Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the U.S. Prospectus.

For the purposes of this Agreement, (i) the term “Preliminary Canadian Prospectus” means the fifth amended and restated preliminary base PREP prospectus dated May 11, 2011; (ii) the term “Final Canadian Prospectus” means the final base PREP prospectus of the Company dated May 25, 2011 relating to the distribution of the Securities, except that, when a Supplemented PREP Prospectus is (A) furnished to the Underwriters for use in connection with the offering of the Securities in Canada, or (B) filed with the Canadian Securities Regulators, the term “Final Canadian Prospectus” shall refer to such Supplemented PREP Prospectus, as applicable; (iii) the term “Canadian Prospectus” means, collectively, the preliminary base PREP prospectus of the Company dated February 22, 2011, the amended and restated preliminary base PREP prospectuses of the Company dated March 14, 2011, April 14, 2011 (which for the purposes of the Qualifying Canadian Jurisdictions other than Alberta and Ontario constituted a preliminary prospectus), April 27, 2011 and May 3, 2011, the Preliminary Canadian Prospectus and the Final Canadian Prospectus; (iv) the term “Canadian Prospectus Amendment” means any amendment to the Final Canadian Prospectus; and (v) the term “Canadian Securities Laws” means the applicable securities statutes in each of the Qualifying Canadian Jurisdictions and the respective rules, regulations and blanket orders and rulings made thereunder, together with any related policy statements and written interpretation notices issued by the Canadian Securities Regulators.

2.                                       Purchase, Sale, and Delivery of the Securities.  On the basis of the representations, warranties, and agreements and subject to the terms and conditions set forth herein, the Company agrees to sell to the several Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at a purchase price of $12.22 per share, the respective number of Securities set forth opposite the names of the Underwriters in Schedule 1 hereto.

The Company will deliver the Firm Securities to or as instructed by the Representative for the accounts of the several Underwriters against payment of the purchase price by the Underwriters in Federal (same day immediately available) funds by wire transfer to an account specified by the Company to the Representative drawn to the order of Lone Pine Resources Inc. at the offices of Simpson Thacher & Bartlett LLP, at 8 A.M., New York time, on June 1, 2011, or

at such other time or place on the same or such other date as the Representative and the Company determine, such time being herein referred to as the “First Closing Date.”  For purposes of Rule 15c6-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Firm Securities sold pursuant to the offering.  The Firm Securities shall be delivered through the facilities of The Depository Trust Company (“DTC”) against payment of the purchase price therefor.

In addition, upon written notice from the Representative given to the Company from time to time not more than 30 days subsequent to the date of the U.S. Prospectus, the Underwriters may purchase all or less than all of the Optional Securities at the purchase price per Security to be paid for the Firm Securities. The Company agrees to sell to the Underwriters the number of Optional Securities specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Optional Securities. Such Optional Securities shall be purchased for the account of each Underwriter in the same proportion as the number of Firm Securities set forth opposite such Underwriter’s name bears to the total number of Firm Securities (subject to adjustment by the Representative to eliminate fractions) and may be purchased by the Underwriters only for the purpose of covering over-allotments made in connection with the sale of the Firm Securities. No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised from time to time during the above-mentioned 30-day period and to the extent not previously exercised may be surrendered and terminated at any time upon notice by the Representative to the Company.

(r)                                    Legal Proceedings.  Except as described in each of the Time of Sale Information, the U.S. Prospectus, and the Final Canadian Prospectus, there are no legal, governmental or regulatory investigations, actions, suits, claims or proceedings (collectively “Legal Proceedings”) pending to which the Company or any of its Subsidiaries is or may be a party or to which any property of the Company or any of its Subsidiaries is or may be the subject that, individually or in the aggregate, if determined adversely to the Company or any of its Subsidiaries, could reasonably be expected to have a Material Adverse Effect; and to the best knowledge of the Company, no such Legal Proceedings are threatened by any governmental or regulatory authority or other third party; and there are no current or pending legal, governmental or regulatory actions, suits or proceedings that are required under the Securities Act to be described in the Time of Sale Information, the U.S. Prospectus, and the Final Canadian Prospectus that are not so described in the Time of Sale Information, the U.S. Prospectus, and the Final Canadian Prospectus.

(s)                                  Independent Accountants.  Ernst & Young LLP, who have certified certain financial statements of each of the Company and CFOL and its consolidated subsidiaries included in the Time of Sale Information, the U.S. Prospectus, and the Final Canadian Prospectus, are (i) independent public accountants with respect to each of the Company and CFOL and its consolidated subsidiaries within the meaning of Rule 101 of the Code of Professional Conduct of the American Institute of Certified Public Accountants and its interpretations and rulings thereunder within the applicable rules and regulations adopted by the Commission and the Public Company Accounting Oversight Board (United States) and as required by the Securities Act; and (ii)  independent with respect to the Company within the meaning of the rules of professional conduct applicable to auditors in the Province of Alberta; and there has not been any reportable event (within the meaning of National Instrument 51-102 — Continuous Disclosure Obligations adopted by the Canadian Securities Regulators (“NI 51-102”)) with such firm or any other prior auditor of the Company.

(t)                                    Information Underlying D&M Report.  The factual information underlying the estimates of the oil and natural gas reserves, which was supplied to DeGolyer and MacNaughton (“D&M”) for the purposes of preparing the reserve reports and estimates of proved reserves disclosed in the Registration Statement, the Time of Sale Information, and the U.S. Prospectus, including production and costs of operation, was true and correct in all material respects on the dates such estimates were made, and such information was supplied and was prepared in accordance with customary industry practices; the estimates of such proved reserves and standardized measure as described in the Registration Statement, the Time of Sale Information, and the U.S. Prospectus and reflected in the report referenced therein have been prepared in a

11

manner that complies with the applicable requirements of the rules under the Securities Act with respect to such estimates.

(u)                                 Information Underlying Canadian D&M Report.  The Company has made available to D&M prior to the issuance of the report of D&M dated February 9, 2011 evaluating the crude oil, natural gas, and natural gas liquids reserves of CFOL as of December 31, 2010 (the “D&M Evaluation Report”), for the purpose of preparing the D&M Evaluation Report, all information requested by D&M, which information did not contain any material misrepresentation at the time such information was provided.  Except with respect to changes in commodity prices, the Company has no knowledge of a material adverse change in any costs, reserves or other relevant information provided to D&M since the dates that such information was so provided.  The Company believes that the D&M Evaluation Report reasonably presents the quantity and pre-tax present worth values of the oil and gas reserves attributable to the crude oil, natural gas, and natural gas liquids properties of the Company evaluated in the D&M Evaluation Report as of December 31, 2010 based upon information available at the time the D&M Evaluation Report was prepared and given the assumptions contained therein, and except with respect to changes in commodity prices, the Company has no knowledge of any material adverse change to such oil, natural gas and natural gas liquids reserves from that disclosed in the D&M Report since the preparation date of the D&M Report.

(v)                                 Title to Real and Personal Property.  As of the First Closing Date and each Optional Closing Date, as the case may be, and except as disclosed in each of the Time of Sale Information, the U.S. Prospectus, and the Final Canadian Prospectus, the Company and its Subsidiaries will have good and marketable title to all material real and personal property of the Company and its Subsidiaries, in each case free and clear of all liens, encumbrances, claims and defects and imperfections of title except those that (i) do not materially interfere with the use made and proposed to be made of such property by the Company and its Subsidiaries or (ii) could not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.

(w)                               Title to Intellectual Property.  As of the First Closing Date and each Optional Closing Date, as the case may be, the Company or its Subsidiaries will own, possess, or can acquire on reasonable terms, adequate rights to use all material patents, patent applications, trademarks, service marks, trade names, trademark registrations, service mark registrations, copyrights, licenses, and know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems, or procedures) necessary for the conduct of their respective businesses; and the Company or its Subsidiaries will not have received any notice of any claim of infringement of or conflict with any rights of others that, if determined adversely to the Company or any of its Subsidiaries would, individually or in the aggregate, have a Material Adverse Effect.

(x)                                   Investment Company Act.  Neither the Company nor any of its Subsidiaries is, and after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in each of the Time of Sale Information, the U.S. Prospectus, and the Final Canadian Prospectus none of them will be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission thereunder (collectively, “Investment Company Act”).

12

(y)                                 Taxes.  The Company and its Subsidiaries have paid all federal, provincial, territorial, state, local, and foreign taxes and filed all tax returns required to be paid or filed through the date hereof (taking into account timely filed extensions), and except as otherwise disclosed in the Time of Sale Information, the U.S. Prospectus, and the Final Canadian Prospectus, there is no tax deficiency that has been, or could reasonably be expected to be, asserted against the Company or any of its Subsidiaries or any of their respective properties or assets, except for any failure to pay, failure to file, or tax deficiency that would not, individually or in the aggregate, have a Material Adverse Effect.

(z)                                   Licenses and Permits.  As of the First Closing Date and each Optional Closing Date, as the case may be, the Company and its Subsidiaries will possess all licenses, certificates, permits, approvals and other authorizations required by, and will have made all required declarations and filings with, the appropriate federal, provincial, territorial, state, local, or foreign governmental or regulatory authorities that are necessary for the ownership, operation or lease of their respective properties or the conduct of their respective businesses as described in each of the Time of Sale Information, the U.S. Prospectus, and the Final Canadian Prospectus, except where the failure to possess or make the same would not, individually or in the aggregate, have a Material Adverse Effect, and except as described in each of the Time of Sale Information, the U.S. Prospectus, and the Final Canadian Prospectus, neither the Company nor any of its Subsidiaries will have received notice of any revocation or modification of any such license, certificate, permit, approval or other authorization, or received notice that any work, repairs, construction or capital expenditures are required to be made by it as a condition of continued compliance with any license, certificate, permit, approval of other authorizations, that if determined adversely to the Company or any of its Subsidiaries, would, individually or in the aggregate, have a Material Adverse Effect.

(aa)                            No Labor Disputes and Compliance with Employment Laws.  No labor disturbance by or dispute with employees of the Company or any of its Subsidiaries exists or, to the best knowledge of the Company, is contemplated or threatened that could reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.  No union has been accredited or otherwise designated to represent any employees of the Company or any of its Subsidiaries and, to the knowledge of the Company, no accreditation request or other representation question is pending with respect to the employees of the Company or any of its Subsidiaries and no collective agreement or collective bargaining agreement or modification thereof has expired or is in effect in any of the facilities of the Company or any of its Subsidiaries, and none is currently being negotiated by the Company or any of its Subsidiaries.   Each of the Company and its Subsidiaries is in compliance with the provisions of all applicable federal, provincial, local and foreign laws and regulations respecting employment and employment practices, terms and conditions of employment and wages and hours, except for any failure to comply that would not, individually or in the aggregate, have a Material Adverse Effect.

(bb)                          Compliance With ERISA. Each “employee benefit plan,” within the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), for which the Company or any member of its “Controlled Group” (defined as any organization which is a member of a controlled group of corporations within the meaning of Section 414 of the Internal Revenue Code of 1986, as amended (the “Code”)) would have any liability (each, a

13

“Plan”) has been maintained in compliance with its terms and the requirements of any applicable statutes, orders, rules and regulations, including but not limited to ERISA and the Code, except for any failure to comply that would not, individually or in the aggregate, have a Material Adverse Effect.  No prohibited transaction, within the meaning of Section 406 of ERISA or Section 4975 of the Code, has occurred with respect to any Plan excluding transactions effected pursuant to a statutory or administrative exemption and transactions that would not, individually or in the aggregate, have a Material Adverse Effect.  For each Plan that is subject to the funding rules of Section 412 of the Code or Section 302 of ERISA, no failure to satisfy the “minimum funding standard” or “minimum required contribution” (as such terms are defined in Section 412 or 430 of the Code or Section 302 of ERISA), whether or not waived, has occurred or is reasonably expected to occur.  The fair market value of the assets of each Plan that is subject to ERISA and is required to be funded under ERISA equals or exceeds the present value of all benefits accrued under such Plan (determined based on those assumptions used to fund such Plan), except for any failure to be so funded that would not, individually or in the aggregate, have a Material Adverse Effect.  No “reportable event”, as defined in Section 4043 of ERISA (other than an event with respect to which the 30-day notice requirement has been waived), has occurred with respect to any Plan.  The Company and any members of the Controlled Group have neither incurred, nor reasonably expect to incur, liability under Title IV of ERISA with respect to the termination of or underfunding of any pension plan.

(cc)                            Compliance With Employee Arrangements.  Each benefit and compensation plan, agreement, policy and arrangement (other than any such plan, agreement, policy, or arrangement covered by Section 3(bb)) that is maintained, administered, or contributed to by the Company or any of its Subsidiaries for current or former employees or directors of, or independent contractors with respect to, the Company or any of its Subsidiaries, or with respect to which any of such entities would reasonably be expected to have any current, future or contingent liability or responsibility, has been maintained in compliance with its terms and the requirements of any applicable statutes, orders, rules and regulations, except for any failure to comply that would not, individually or in the aggregate, have a Material Adverse Effect.

(dd)                          Compliance With Environmental Laws.  Except as would not, individually or in the aggregate, have a Material Adverse Effect, neither the Company nor any of its Subsidiaries: (i) has violated or is in violation of any statute, law (including, without limitation, common law), rule, regulation, decision, or order of any governmental authority or any court, domestic or foreign, relating to protection of the environment or of human health and safety, including, without limitation, with respect to the use, disposal, or release of hazardous or toxic substances or wastes, pollutants or contaminants (collectively, “Environmental Laws”); (ii)  owns, leases or operates any real property that contains as of the Closing Date any hazardous or toxic substance or waste, pollutant or contaminant in amounts or under conditions that could reasonably be expected to result in liability under any Environmental Laws; (iii) is liable for any onsite or offsite release or disposal of any hazardous or toxic substances or wastes, pollutants or contaminants pursuant to any Environmental Laws, or (iv) is subject to any pending or, to Company’s knowledge, threatened Legal Proceedings relating to any Environmental Laws, and to the Company’s knowledge, there is no pending or threatened investigation which could reasonably be expected to result in such a Legal Proceeding.

14

(ee)                            No Broker’s Fees.  Neither the Company nor any of its Subsidiaries is a party to any contract, agreement, or understanding with any person (other than this Agreement) that would give rise to a valid claim against any of them or any Underwriter for a brokerage commission, finder’s fee or other like payment in connection with the offering and sale of the Securities contemplated hereby.

(ff)                                Disclosure Controls.  The Company and its Subsidiaries maintain an effective system of “disclosure controls and procedures” (as defined in Rule 13a-15(e) of the Exchange Act) that are designed to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms, including controls and procedures designed to ensure that such information is accumulated and communicated to the Company’s management as appropriate to allow timely decisions regarding required disclosure.

(gg)                          Accounting Controls.  The Company and its Subsidiaries maintain a system of “internal control over financial reporting” (as defined in Rule 13a-15(f) of the Exchange Act) that (i) pertains to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company and its Subsidiaries; (ii) provides reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company and its Subsidiaries are being made only in accordance with authorizations of management and directors of the Company and its Subsidiaries, as applicable; and (iii) provides reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s or any of its Subsidiary’s assets that could have a material effect on the financial statements.  Except as disclosed in the Time of Sale Information, the U.S. Prospectus, and the Final Canadian Prospectus as of December 31, 2010, there are no significant deficiencies or material weaknesses in the internal controls of the Company and its Subsidiaries.

(hh)                          Absence of Significant Acquisition.  No acquisition has been made by the Company or CFOL since January 1, 2010 that is a “significant acquisition” for the purposes of Item 35 of Form 41-101F1 of the Canadian Securities Administrators and, other than the Company’s proposed acquisition of Forest’s direct and indirect ownership interests in CFOL, no proposed acquisition by the Company of a business or related businesses has progressed to a state where a reasonable person would believe that the likelihood of the Company completing the acquisition is high and that, if completed by the Company at the date of the Final Canadian Prospectus, would be a “significant acquisition” for the purposes of Item 35 of Form 41-101F1, in each case, that would require the prescribed disclosure in the Final Canadian Prospectus pursuant to Canadian Securities Laws.

(ii)                                  Related Party Agreements.  No director or officer, former director or officer, or stockholder or employee of, or any other person not dealing at arm’s length with, the Company will continue after the First Closing Date to be engaged in any transaction or arrangement with or to be a party to a contract with, or has any indebtedness, liability, or obligation to, the Company, except (i) as disclosed in the Time of Sale Information, the U.S. Prospectus, and the Final Canadian Prospectus, (ii) for employment or consulting arrangements with employees or

15

consultants or those serving as a director or officer of the Company as described in the Time of Sale Information, the U.S. Prospectus and the Final Canadian Prospectus, and (iii) for indemnity agreements to which the Company and current or former officers or directors are party.

(jj)                                  Share Certificate.  The form of the certificate for the Common Stock has been approved by the board of directors of the Company and adopted by the Company and will comply with all legal and stock exchange requirements and will not conflict with the Company’s charter documents.

(kk)                            Absence of Restrictions by Canadian Securities Commissions.  None of the Canadian Securities Regulators, TSX, or comparable Canadian authority has issued any order:  (i) requiring trading in any of the Company’s securities to cease, (ii) preventing or suspending the use of the Preliminary Canadian Prospectus, the Final Canadian Prospectus, or any Canadian Prospectus Amendment, or (iii) preventing the distribution of the Securities in any Qualifying Canadian Jurisdiction.  The Company has not been informed that any such proceedings have been instituted for that purpose and, to the knowledge of the Company, no such proceedings are pending or contemplated.

(ll)                                  Transfer Agent.  BNY Mellon Shareowner Services, at its principal office in the city of Jersey City, New Jersey, has been duly appointed as U.S. registrar and transfer agent for the Common Stock of the Company, and Equity Financial Trust Company, at its principal offices in the cities of Calgary, Alberta and Toronto, Ontario, has been duly appointed as Canadian registrar and transfer agent for the Common Stock of the Company.

(mm)                      Insurance.  The Company and its Subsidiaries have insurance covering their respective properties, operations, personnel, and businesses, which insurance is in amounts and insures against such losses and risks as are adequate to protect the Company and its Subsidiaries and their respective businesses; and neither the Company nor any of its Subsidiaries has (i) received notice from any insurer or agent of such insurer that capital improvements or other expenditures are required or necessary to be made in order to continue such insurance or (ii) any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage at reasonable cost from similar insurers as may be necessary to continue its business.

(nn)                          No Unlawful Payments.  Neither the Company nor any of its Subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee or other person associated with or acting on behalf of the Company or any of its Subsidiaries has (i) made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds; (ii) violated or is in violation of any provision of the Foreign Corrupt Practices Act of 1977, as amended, or the equivalent legislation of any other jurisdiction to which the Company is subject; or (iii) made any bribe, rebate, payoff, influence payment, kickback or other unlawful payment.

(oo)                          Compliance with Money Laundering Laws.  The operations of the Company and its Subsidiaries are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the Proceeds of Crime (Money Laundering) and Terrorist Financing

16

Act (Canada), the equivalent money laundering statutes of any other jurisdiction to which the Company is subject, the rules and regulations thereunder, and any related or similar rules, regulations, or guidelines, issued, administered, or enforced by any governmental authority (collectively, the “Money Laundering Laws”), and to the knowledge of the Company no action, suit, or proceeding by or before any court, arbitrator, or governmental authority involving the Company or any of its Subsidiaries with respect to the Money Laundering Laws is pending or threatened.

(pp)                          Compliance with OFAC.  None of the Company, any of its Subsidiaries or, to the knowledge of the Company, any director, officer, agent, employee, or affiliate of the Company or any of its Subsidiaries, is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Department of the Treasury (“OFAC”); and the Company will not, directly or indirectly, use the proceeds of the offering of the Securities hereunder, or lend, contribute, or otherwise make available such proceeds to any subsidiary, joint venture partner, or other person or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC.

(qq)                          No Stabilization.  The Company has not taken, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Common Stock.

(rr)                                Margin Rules.  Neither the issuance, sale and delivery of the Securities nor the application of the proceeds thereof by the Company as described in each of the Time of Sale Information, the U.S. Prospectus and the Final Canadian Prospectus will violate Regulation T, U, or X of the Board of Governors of the Federal Reserve System or any other regulation of such Board of Governors.

(ss)                            Forward-Looking Statements.  No forward-looking statement (within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act) contained in any of the Time of Sale Information or the U.S. Prospectus has been made or reaffirmed without a reasonable basis or has been disclosed other than in good faith. The Company has a reasonable basis for all information in the Final Canadian Prospectus that would be considered “forward-looking information” as defined in NI 51-102.

(tt)                                Statistical and Market Data.  Nothing has come to the attention of the Company that has caused the Company to believe that the statistical and market-related data included in each of the Time of Sale Information, the U.S. Prospectus, and the Final Canadian Prospectus is not based on or derived from sources that are reliable and accurate in all material respects.

(uu)                          Sarbanes-Oxley Act.  The Company is in compliance in all material respects with the applicable provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith.

4.                                       Further Agreements of the Company.  Each of Forest (solely with respect to Section 4(s)) and the Company covenants and agrees with each Underwriter that:

(d)                                 Delivery of Canadian Documents.  On or prior to the time of filing of the Supplemented PREP Prospectus, the Company shall deliver to the Representative (except to the extent such documents have been previously delivered to the Representative or are available on the SEDAR website) a copy of:  (i) each of the Preliminary Canadian Prospectus, the Final Canadian Prospectus, and the Supplemented PREP Prospectus, in each case signed and certified by the Company as required by Canadian Securities Laws; (ii) the U.S. Prospectus (including all amendments and supplements thereto and each Issuer Free Writing Prospectus) and (iii) any other document required to be filed by the Company under Canadian Securities Laws at or before such time in respect of the offering of the Securities.

(g)                                 Amendments to Canadian Prospectus.  In the event that the Company is required by Canadian Securities Laws to prepare and file a Canadian Prospectus Amendment, the Company shall prepare and deliver promptly to the Underwriters signed and certified copies of such Canadian Prospectus Amendment. Any Canadian Prospectus Amendments shall be in form and substance satisfactory to the Underwriters, acting reasonably.

(h)                                 Notice to the Representative.  The Company will advise the Representative promptly, (i) when the Registration Statement has become effective, (ii) when any amendment to the Registration Statement has been filed or becomes effective, (iii) when any supplement to the U.S. Prospectus or any Issuer Free Writing Prospectus or any amendment to the U.S. Prospectus has been filed, (iv) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the U.S. Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information, (v) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary U.S. Prospectus, any of the Time of Sale Information or the U.S. Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act, (vi) of the occurrence of any event within the U.S. Prospectus Delivery Period as a result of which the U.S. Prospectus, the Time of Sale Information or any Issuer Free Writing Prospectus as then amended or supplemented would include any untrue

19

statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing when the U.S. Prospectus, the Time of Sale Information, or any such Issuer Free Writing Prospectus is delivered to a purchaser, not misleading, (vii) of the time when the Supplemented PREP Prospectus or any Canadian Prospectus Amendment has been filed and when the receipt(s) in respect thereof, if any, have been obtained and will provide evidence satisfactory to the Underwriters of each filing and the issuance or deemed issuance of receipts from all of the Canadian Securities Regulators, (viii) of the issuance by any Canadian Securities Regulator of any order suspending or preventing the use of the Preliminary Canadian Prospectus, the Final Canadian Prospectus (including the Supplemented PREP Prospectus), or any Canadian Prospectus Amendment or suspending the qualification of the Securities for distribution in any of the Qualifying Canadian Jurisdictions, (ix) of the receipt by the Company of any requests made by any Canadian Securities Regulator for any amendment or supplement to the Final Canadian Prospectus, or for additional information, and (x) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Securities for offer and sale in any other jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its commercially reasonable efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing the distribution of the Securities in the Qualifying Canadian Jurisdictions, preventing or suspending the use of any Preliminary U.S. Prospectus, any of the Time of Sale Information, the U.S. Prospectus, or the Final Canadian Prospectus, or suspending any such qualification of the Securities and, if any such order is issued, will take commercially reasonable steps to obtain as soon as practicable the withdrawal thereof.

In addition, during the period from the date of this Agreement to the later of the final Closing Date and the date of completion of distribution of the Securities, the Company shall promptly notify the Representative in writing of any of the representations or warranties made by the Company in this Agreement no longer being true and correct in all material respects at any particular time (but following the closing time, after giving effect to the transactions contemplated by this Agreement and the Transaction Documents), except in respect of any representations and warranties that are to be true and correct as of a specified date (in which case the Company shall notify the Underwriters if the representations or warranties are no longer true and correct as of that date), and except in respect of any representations and warranties that are subject to a materiality qualification, in which case they will be true and correct in all respects.

5.             Certain Agreements of the Underwriters.  The Underwriters hereby represent to, and agree with, the Company as follows:

(a)           Each Underwriter has not and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus”, as defined in Rule 405 under the Securities Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company) other than (i) a free writing prospectus that, solely as a result of use by such underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433, (ii) any Issuer Free Writing Prospectus prepared pursuant to Section 3(c) or Section 4(c) above (including any electronic road show), or (iii) any free writing prospectus prepared by such underwriter and approved by the Company in advance in writing (each such free writing prospectus referred to in clauses (i) or (iii), an “Underwriter Free Writing U.S. Prospectus”).

(b)           Each Underwriter is not subject to any pending proceeding under Section 8A of the Securities Act with respect to the offering (and will promptly notify the Company if any such proceeding against it is initiated during the U.S. Prospectus Delivery Period).

(c)           The Underwriters will be permitted to appoint, at their sole expense, other registered dealers or brokers as their agents to assist in the distribution of the Securities in the Qualifying Canadian Jurisdictions (a “Selling Firm”).  The Underwriters shall, and shall require any Selling Firm, to comply with Canadian Securities Laws in connection with the distribution of the Securities and to offer the Securities for sale only in the Qualifying Canadian Jurisdictions directly and through duly appointed Selling Firms upon the terms and conditions set forth in the Final Canadian Prospectus and this Agreement.  The Underwriters shall, and shall require any Selling Firm to agree to, offer for sale and sell the Securities only in those jurisdictions where they may be lawfully offered by the Underwriters for sale or sold.  Without limiting the

23

generality of the foregoing, no Securities will be offered for sale or sold in any Qualifying Canadian Jurisdiction by any Canadian Underwriter or any Selling Firm unless such Canadian Underwriter or Selling Firm is duly registered as a dealer under the Canadian Securities Laws of such Qualifying Canadian Jurisdiction in a category that permits the trade.  For the purposes of this Section 5(c), the Underwriters shall be entitled to assume that the Securities are qualified for distribution in each of the Qualifying Canadian Jurisdictions.

(d)           Notwithstanding the foregoing, an Underwriter will not be liable for any breach under this Section 5 by another Underwriter if the Underwriter first mentioned is not itself also in breach of this Section 5.

(e)           The Canadian Underwriters shall use their commercially reasonable efforts to complete, and to cause each Selling Firm to complete, the distribution of the Securities as promptly as possible after the Closing Date, and shall, and shall cause each Selling Firm to, after the Closing Date, give prompt written notice to the Company when, in the opinion of the Canadian Underwriters, they have completed distribution of the Securities in the Qualifying Canadian Jurisdictions, including notice of the total proceeds realized or number of Securities sold in each of the Qualifying Canadian Jurisdictions and any other jurisdiction.

(f)            (i) The U.S. Underwriters and, except as provided in section (f)(ii) below, the Company shall use the “road show” presentation prepared specifically for U.S. investors in connection with the offering of the Securities in the United States; provided that each of the Company, Forest and the Underwriters acknowledge that there shall be no obligation to verify the identity of any investor purporting to be a U.S. investor other than requesting that such investor respond to click-through prompts accompanying the “road show” to verify that  such investor is a U.S. investor, and (ii) the Canadian Underwriters and, except as provided in section (f)(i) above, the Company shall use the “road show” presentation prepared specifically for Canadian investors in connection with the offering of the Securities in Canada; provided that each of the Company, Forest and the Underwriters acknowledge that there shall be no obligation to verify the identity of any investor purporting to be a Canadian investor other than requesting that such investor respond to click-through prompts accompanying the “road show” to verify such investor is a Canadian investor.

6.             Conditions of Underwriters’ Obligations.  The obligation of each Underwriter to purchase Securities on each Closing Date as provided herein is subject to the performance by the Company and Forest of their respective covenants and other obligations hereunder and to the following additional conditions:

24

(ii)           No order to cease or suspend trading in any securities of the Company or prohibiting or restricting the distribution of any of the Securities shall have been made, or proceedings announced, commenced, or threatened for the making of any such order, by any Canadian Securities Regulator or any other competent authority, that has not been rescinded, revoked, or withdrawn, and the Securities shall continue to be qualified for distribution in the Qualifying Canadian Jurisdictions pursuant to the Final Canadian Prospectus.

27

of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading; (ii) any untrue statement or alleged untrue statement of a material fact contained in the Time of Sale Information, any Issuer Free Writing Prospectus, or the U.S. Prospectus (or any amendment or supplement thereto) or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except in each of (i) and (ii) insofar as such losses, claims, damages, or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company and Forest by such Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 7(b) hereof; and (iii) any (A) information or statement (except any Canadian Underwriters’ Information) contained in the Canadian Prospectus, any Canadian Prospectus Amendment, or in any certificates of the Company delivered pursuant to this Agreement which at the time and in the light of the circumstances under which it was made contains or is alleged to contain a misrepresentation; (B) omission or alleged omission to state in the Canadian Prospectus or any Canadian Prospectus Amendment, any material fact (other than a material fact relating solely to any Canadian Underwriters’ Information) required to be stated in such document (C) order made or enquiry, investigation or proceedings commenced or threatened by any court, securities commission or other competent authority based upon any misrepresentation or alleged misrepresentation (in each case, other than relating solely to any Canadian Underwriters’ Information) contained in or omitted from the Canadian Prospectus or any Canadian Prospectus Amendment or based upon any failure to comply with Canadian Securities Laws (other than any failure or alleged failure to comply by the Underwriters), preventing or restricting the trading in or the sale or distribution of the Securities in any of the Qualifying Canadian Jurisdictions; and (D) non-compliance or alleged non-compliance by the Company with any Canadian Securities Laws in connection with the transactions contemplated by this Agreement.  Notwithstanding anything to the contrary in this Agreement, Forest’s indemnification obligation pursuant to this Section 7(a) and its contribution obligations pursuant to Section 7(d) hereof are limited to indemnification and contribution for claims that are both (i) made against any Underwriter or its Participating Affiliates, directors, officers or each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and (ii) reported to Forest in writing pursuant to Section 7(c) and Section 14(b) hereof prior to the consummation of the Spin-off.

(b)           Indemnification of the Company and Forest.  Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless (i) the Company, each of its directors and officers, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and (ii) until the consummation of the Spin-Off, Forest, each of its directors and officers, and each person, if any, who controls Forest within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, in each case, to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company and Forest by such Underwriter through the Representative expressly for use in the Time of Sale Information, any

28

Issuer Free Writing Prospectus, the U.S. Prospectus (or any amendment or supplement thereto), the Canadian Prospectus or any Canadian Prospectus Amendment, it being understood and agreed that the only such information consists of the fourth, fifteenth, sixteenth, seventeenth and the material relationships described in the twenty-fourth paragraph under “Underwriting” in the Preliminary U.S. Prospectus and U.S. Prospectus and the fourth, fifteenth, sixteenth, seventeenth and the material relationships described in the twenty-fourth paragraph under the heading “Underwriting” in the Preliminary Canadian Prospectus and Final Canadian Prospectus.

(c)           Notice and Procedures.  If any suit, action, proceeding (including any governmental or regulatory investigation), claim, or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure and except as otherwise provided with respect to Forest under paragraph (a) above; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraphs (a) or (b) above.  If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) and any others entitled to indemnification pursuant to paragraphs (a) or (b) above that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred.  In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them.  It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred.  Any such separate firm for any Underwriter, its Participating Affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representative and any such separate firm for the Company, its directors, its officers, and any control persons of the Company shall be designated in writing by the Company.  The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment.  Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person

29

reimburse the Indemnified Person for fees and expenses of counsel in connection with a suit, action, proceeding, claim, or demand in respect of which indemnification is permitted under either paragraph (a) or (b) above, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into (A) more than 60 days after receipt by the Indemnifying Person of such request and (B) more than 30 days after receipt by the Indemnifying Person of the terms of the proposed settlement and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement.  No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d)           Contribution.  If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and Forest on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and Forest on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages, or liabilities, as well as any other relevant equitable considerations.  The relative benefits received by the Company and Forest on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company and Forest from the sale of the Securities and the total discounts and commissions received by the Underwriters in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities.  The relative fault of the Company and Forest on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and Forest or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e)           Limitation on Liability.  The Company, Forest and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above.  The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages, and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim.  Notwithstanding the provisions

of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person found guilty in a final judgment of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f)                                    Non-Exclusive Remedies.  The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

8.                                       Termination.  This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company and Forest, if after the execution and delivery of this Agreement and on or prior to the First Closing Date (i) trading generally shall have been suspended or materially limited on the NYSE, The Nasdaq Stock Market, the TSX, or the over-the-counter market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by U.S. or Canadian federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representative, is material and adverse and makes it impracticable, inadvisable, or unprofitable to proceed with the offering, sale, or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information, the U.S. Prospectus and the Final Canadian Prospectus.

9.                                       Defaulting Underwriter.  (a) If, on a Closing Date any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement.  If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms.  If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone such Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Time of Sale Information, the U.S. Prospectus, the Final Canadian Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Time of Sale Information, the U.S. Prospectus, or the Final Canadian Prospectus that effects any such changes.  As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

31

(b)                                 If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the number of such Securities that remains unpurchased does not exceed one-eleventh of the number of all the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the number of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c)                                  If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the number of such Securities that remains unpurchased exceeds one-eleventh of the aggregate number of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters.  Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 10(a) hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d)                                 Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

10.                                 Payment of Expenses.  (a)  Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including, without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities, and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary U.S. Prospectus, any other Time of Sale Information, any Issuer Free Writing Prospectus, and the U.S. Prospectus (including any amendment or supplement thereto) and the distribution thereof; (iii) the costs incident to the preparation, printing, and filing under Canadian Securities Laws of the Preliminary Canadian Prospectus, the Final Canadian Prospectus and any Canadian Prospectus Amendment; (iv) the fees and expenses of the Company’s counsel, independent accountants, and independent petroleum engineering firms; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the state or foreign securities or blue sky laws of such jurisdictions as the Representative may designate and the preparation, printing, and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters); (vi) the cost of preparing stock certificates; (vii) the costs and charges of any transfer agent and any registrar; (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, FINRA; (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; and (x) all expenses and application fees related to listing of the Securities on the NYSE and the TSX; provided, that except as provided in this Section 10 and in Section 7 hereof, the Underwriters shall pay their own costs and expenses, including the costs and expenses of their counsel.

32

(b)                                 If (i) this Agreement is terminated pursuant to clause (ii) of Section 8, (ii) the Company for any reason fails to tender the Securities for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Securities because a condition to closing is not satisfied, the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

12.                                 Survival.  The respective indemnities, rights of contribution, representations, warranties, and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Underwriters.
