On January 3, 2017, Eclipse Resources Corporation (the “Company”) announced that, effective January 1, 2017: (i) Thomas S. Liberatore has assumed the new position of Executive Vice President, Corporate Development and Geosciences of the Company and will no longer serve as the Company’s Chief Operating Officer, and (ii) Oleg Tolmachev has been appointed Executive Vice President and Chief Operating Officer of the Company.

Oleg Tolmachev, age 41, previously served as the Company’s Vice President, Drilling & Completions since February 2013. Prior to joining the Company, from April 2011 to February 2013, Mr. Tolmachev served as the Senior Asset Manager, Utica Shale with Chesapeake Energy Corporation where he was responsible for leading an asset team comprised of land, geology, drilling, resource development and operations for Chesapeake Energy Corporation’s Utica Shale projects in Ohio. Prior to joining Chesapeake Energy Corporation, from August 2008 to 2011, Mr. Tolmachev held the position of Group Lead Completions, Mid-Continent Business Unit at EnCana Oil and Gas (USA) Inc. where he managed well completions and intervention operations in its Barnett Shale, Deep Bossier and East Texas Haynesville Shale business units. Mr. Tolmachev received his Bachelors of Science degree in Petroleum Engineering from the University of Oklahoma.

In connection with Mr. Tolmachev’s appointment as the Company’s Executive Vice President and Chief Operating Officer, the Company and Mr. Tolmachev entered into an amended and restated executive employment agreement, dated as of January 1, 2017 (the “Employment Agreement”).

The Employment Agreement is for a term of three years, and automatically extends for an additional one-year renewal term for every year thereafter unless the Company or Mr. Tolmachev gives written notice to the other party that the automatic extension will not occur at least 90 days prior to the end of the initial term, or, if applicable, the then-current renewal term, in each case, unless terminated earlier in accordance with the terms and conditions set forth therein. Pursuant to the terms of the Employment Agreement, Mr. Tolmachev will (i) receive an annual base salary of $355,000 and (ii) be eligible to receive an annual performance-based bonus with a target value equal to 85% of his base salary. The base salary and the annual performance-based bonus percentage may be increased by the Company’s Board of Directors or a designated committee thereof in its discretion but may not be decreased without Mr. Tolmachev’s written consent.

The Employment Agreement also provides Mr. Tolmachev with certain severance benefits upon termination. If Mr. Tolmachev’s employment is terminated by the Company “without Cause” or by Mr. Tolmachev for “Good Reason” (as such terms are defined in the Employment Agreement), then:

If Mr. Tolmachev’s employment is terminated upon his death or “Disability” (as defined in the Employment Agreement), then the Company will make a lump sum payment to Mr. Tolmachev equal to one times his annual base salary as of the termination date and the Company will provide him with the Post-Employment Health Coverage.

The Employment Agreement also contains non-solicitation, non-competition and confidentiality covenants on behalf of Mr. Tolmachev in favor of the Company. In addition, any amounts payable to Mr. Tolmachev under the Employment Agreement will be subject to any “clawback” policy established by the Company from time to time.
