                  Executive's employment hereunder, and for a period of two (2)
                  years following the termination of such employment for any
                  reason whatsoever, Executive shall not employ or solicit the
                  employment of any employee of the Company who was an employee
                  of the Company at any time during the six (6) months preceding
                  the termination of Executive's employment with the Company,
                  for the purpose of causing such employee to take employment
                  with Executive or a competitor of the Company.

                  Executive agrees and acknowledges that the restrictions in
this Agreement are not vague, over broad or indefinite, and are reasonable and
designed to protect the legitimate business interests of the Company. In
addition to any other remedies which Company may have under the law for breach
of any or all of said covenants, Company shall be entitled to injunctive and/or
other equitable relief against Executive for any violation of any of said
Covenants.

         6.       Survival. Paragraphs 2, 3, 4, 5, and 6 hereof, together with
any provisions of the Company's Operations Policies expressly or by necessary
implication applicable after the termination of employment, shall survive
termination of this Agreement. Upon termination, Executive shall repay to
Company immediately any advances by Company, not offset by earnings or other
credits due him or her, even if not expressly made repayable at the time of such
advance, it being the intent of the parties that all such advances shall be
repayable as provided by this paragraph. Company may offset any sums owed to
Company by Executive against any amounts otherwise owed by Company to Executive.
No sums otherwise due Executive at termination shall be payable to Executive if,
at the time of termination or thereafter, Executive shall be in violation of any
term or provision of this Agreement.
