Barry Golsen will continue to serve as a member of the Company’s Board of Directors.

As part of the succession planning, the Board of Directors also appointed Mark T.

Effective as of the Company’s 2015 Annual Meeting of Shareholders, Mr. Shelby will transition from CFO to the role of Executive Vice President to ensure a methodical and successful transition.

The Board of Directors has also approved and directed the Company to enter into an amendment to Jack Golsen’s previously-disclosed existing Employment Agreement to provide that (a) he will serve as an executive officer of the Company in the capacity of Executive Chairman of the Board of Directors; and (b) the term of his employment agreement will be three years and will be automatically renewed for two additional terms of one year each, unless the Company or Jack Golsen provides notice of termination six months prior to the expiration of the then current term. The amendment will further provide, among other things, that, upon becoming the Executive Chairman of the Board, Jack Golsen’s responsibilities will generally include assisting the CEO and President in developing overall corporate strategy and providing leadership, and building consensus, in conjunction with the CEO and President, in the development of the Corporation’s overall strategic plan, capital markets activities and corporate development initiatives within the context of the corporate strategy. In addition, among other responsibilities, he will chair all Board of Director meetings, serve as the spokesperson for the Board, manage the Board’s functions, coordinate with management to keep the Board informed, and assist senior management with employee, customer, and stockholder relations. Prior to such amendment, the term of his Employment Agreement would expire on March 21, 2017, but would have been automatically renewed for one additional three-year period and thereafter automatically renew for additional three-year periods, unless terminated by the Company or Jack Golsen at least one year prior to the expiration of the then current term. The amendment to Jack Golsen’s Employment Agreement is effective January 1, 2015.
