§ 680.12 One-year NSF post-employment restrictions.

(a) For one year after leaving NSF employment, a former NSF employee, including a special Government employee who has performed work for NSF on more than 60 days in the previous twelve months, shall not represent himself, herself, or any other person in dealings with any NSF official on any proposal, project, or other particular matter.

(b) The one-year restriction contained in paragraph (a) of this section is in addition to any post-employment restriction imposed by statute, including 18 U.S.C. 207 and 41 U.S.C. 423. To the extent that any disqualification required by paragraph (a) of this section is not also required by statute, written exceptions may be granted by the NSF's General Counsel, whose decisions shall be final. Exceptions will be rare and will be granted only where strict application of the rules would result in undue hardship for former short-term employees or for other former employees, and when granting an exception would not result in an unfair advantage to the former employee.
