Item 1.01.                                        Entry into a Material Definitive Agreement.

On November 13, 2012, Lone Pine Resources Inc.’s (“Lone Pine”) wholly-owned subsidiary, Lone Pine Resources Canada Ltd. (“LPR Canada”) entered into an Agreement for Purchase and Sale (the “Agreement”) with Canadian Natural Resources Limited (“CNRL”), pursuant to which LPR Canada has agreed to sell to CNRL certain natural gas properties located in the Wild River area of Alberta, Canada (the “Wild River Assets”). The effective date of the purchase and sale of the Wild River Assets is October 1, 2012 (the “Effective Date”). The transaction is expected to close on or about December 14, 2012, subject to certain customary closing conditions, as described below.

The total consideration to be received by LPR Canada for the Wild River Assets is Cdn$82,000,000 in cash, subject to customary adjustments to reflect the operation of the Wild River Assets prior to the closing, and the effect of any uncured title defects or environmental defects (the “Purchase Price”).  Upon executing the Agreement, CNRL delivered to a third party escrow agent a letter of credit in the amount of Cdn$8,200,000 (the “Deposit”).

The Agreement contains customary representations and warranties and covenants.  Among other things, closing of the transaction is conditional on: (i) the representations and warranties of LPR Canada and CNRL in the Agreement being true in all material respects; (ii) all obligations of LPR Canada and CNRL required to be performed under the Agreement prior to closing having been performed; (iii) all preferential, pre-emptive or first purchase rights of third parties having been exercised or waived; and (iv) satisfaction of the applicable requirements of the Competition Act (Canada).

The Agreement provides LPR Canada and CNRL certain termination rights, including, among others: (i) the parties may terminate by mutual consent; (ii) LPR Canada may terminate if, on or before the closing, the sum of the aggregate uncured title defects and aggregate cost of resolving identified uncured environmental defects exceeds 8% of the Purchase Price; (iii) CNRL may terminate if, on or before closing, the sum of the aggregate uncured title defects and aggregate cost of resolving identified uncured environmental defects exceeds 15% of the Purchase Price; (iv) LPR Canada may terminate if, at or prior to the closing all representations and warranties of CNRL are not true in all material respects, or if CNRL has not performed all of its obligations set forth in the Agreement in all material respects; and (v) CNRL may terminate if, at or prior to the closing all representations and warranties of LPR Canada are not true in all material respects, or if LPR Canada has not performed all of its obligations set forth in the Agreement in all material respects. LPR Canada may retain the Deposit if the Agreement is terminated for any reason other than as set forth in clauses (i), (ii), (iii) or (v) above.

The foregoing is not a complete description of all of the terms and provisions of the Agreement and is qualified in its entirety by reference to the full text of the Agreement, a copy of which is attached as an exhibit to this Current Report on Form 8-K and incorporated herein by reference.
