On December 10, 2015, Midstates Petroleum Company, Inc. (the “Company”) announced that Mark E. Eck, Executive Vice President & Chief Operating Officer of the Company, would resign from his position effective January 4, 2016 to pursue other opportunities.  Subsequent to Mr. Eck’s departure, his duties and responsibilities will be assumed by other members of the Company’s management team.  Mr. Eck did not resign due to any disagreement with the Company or any matter relating to the Company’s operations, policies or practices.

In connection with his resignation, Mr. Eck entered into an agreement (the “Separation Agreement”) with the Company pursuant to which Mr. Eck resigned as an officer of the Company effective January 4, 2016.  Pursuant to the Separation Agreement, Mr. Eck will receive a lump sum payment equivalent to his accrued 2015 short term incentive bonus, to be paid in such amount and at such time (which shall be no earlier than January 1, 2016 but no later than March 14, 2016) as the Company’s Board of Directors determines.  Such payment shall be no less than Mr. Eck’s current base salary multiplied by his 2015 target incentive percentage multiplied by the corporate bonus percentage award as approved by the Company’s Board of Directors pursuant to the terms and conditions of the Company’s 2015 Short-Term Incentive Plan, less applicable taxes and withholdings.  Pursuant to the terms of Company’s 2012 Long-Term Incentive Plan, any unvested shares of restricted stock which were previously awarded to Mr. Eck will expire on January 4, 2016.

The Separation Agreement also contains confidentiality, non-competition, non-solicitation and non-disparagement provisions and a waiver and release.

The foregoing description of the Separation Agreement is not complete and is qualified by reference to the complete document, which is attached hereto as Exhibit 10.1 and incorporated herein by reference.
