Subject to the satisfaction or waiver in writing of each of the conditions set forth in Section 5 below and in reliance upon the representations, warranties, covenants and agreements contained in this Agreement, the Lenders party hereto, hereby grant the Limited Waivers. The Limited Waivers provided in this Section 3 shall apply solely with regard to the Specified Over-Hedging Event and solely to the extent the Specified Over-Hedging Event results or resulted from the Bakken Sale, and nothing contained in this Agreement shall be deemed a consent to, or waiver of, any other action or inaction of the Loan Parties that constitutes (or would constitute) a violation of or a departure from any provision of the Credit Agreement or any other Loan Document, or which constitutes (or would constitute) a Default or Event of Default. The Limited Waivers described in this Section 3 are

each a one-time waiver limited to the Specified Over-Hedging Event. Neither the Lenders nor the Administrative Agent shall be obligated to grant any future waivers, consents or amendments with respect to Section 6.18 of the Credit Agreement or any other provision of the Credit Agreement or of any other Loan Document. Other than the Limited Waivers expressly provided for in this Section 3, the Loan Parties hereby agree and acknowledge that no course of dealing and no delay in exercising any right, power or remedy conferred on the Administrative Agent or any Lender in the Credit Agreement or in any other Loan Document or now or hereafter existing at law, in equity, by statute or otherwise shall operate as a waiver of or otherwise prejudice any such right, power or remedy.
