The Contractor shall not use or permit the solicitation for or securing of any agreement or employment in connection with this Agreement upon an agreement or arrangement for payment, either directly or indirectly, of a commission, percentage, brokerage, or contingent fee. If Federal funds are used to pay the Contractor under this Agreement, no part of the money appropriated by any enactment of Congress shall, in the absence of express authorization by Congress, be used directly or indirectly to pay for any personal service, advertisement, telegram, telephone, letter, printed or written matter, or other device, intended or designed to influence in any manner a member of Congress, to favor or oppose, by vote or otherwise, any legislation or appropriation by Congress, whether before or after the introduction of any xxxx or resolution proposing such legislation or appropriation; but this shall not prevent officers or employees of the United States or of its departments or agencies from communicating to members of Congress on the request of any member or to Congress, through the proper official channels, requests for legislation or appropriations which they deem necessary for the efficient conduct of the public business. 18 U.S.C. § 1913 (2002).
