1 INTERCORPORATE SERVICES AGREEMENT This INTERCORPORATE SERVICES AGREEMENT (the "Agreement"), effective as of January 1, 1994, is entered into by and between CONTRAN CORPORATION ("Contran"), a Delaware corporation, and NL INDUSTRIES, INC. ("Recipient"), a New Jersey corporation. W I T N E S S E T H: WHEREAS, Harold C. Simmons, an employee of Contran and a director and the Chairman of the Board of Recipient, performs certain advisory functions for Recipient, which functions are unrelated to his function as a director and the Chairman of the Board of Recipient, without direct compensation from Recipient; and WHEREAS, Recipient does not separately maintain the full internal capability to perform all necessary advisory functions which Recipient requires; and WHEREAS, the cost of engaging the advisory services of someone possessing Mr. Simmons' expertise and the cost of maintaining the personnel necessary to perform the functions provided for by this Agreement would exceed the fee set forth in Section 3 of this Agreement and the terms of this Agreement are no less favorable to Recipient than could otherwise be obtained from a third party for comparable services; and WHEREAS, Recipient desires to continue receiving the advisory services of Harold C. Simmons which in the past have been provided by Contran indirectly, pursuant to certain intercorporate services agreements between the Recipient and Valhi, Inc., an affiliate of Contran, and Contran is willing to continue to provide such services directly under the terms of this Agreement.
