    WHEREAS,
the Company recognizes the substantial contributions the Employee has made to
the Company in such position; and

    


    WHEREAS,

    WHERAS,

Employee may be subject to the requirements of Section 409A of the Internal
Revenue Code of 1986, as amended (the “Code”);

    


    NOW,
THEREFORE, in consideration of the continued service of the Employee and the
mutual covenants and agreements herein contained, the Company and the Employee
hereby agree as follows:

              Term
      of Agreement; Employment Status

            


    

    


    (a)           This
Agreement shall be in effect from the effective date hereof throughout the
period of the Employee’s employment with the Company.  In the event of
a “Change-in-Control” of the Company (as defined herein), this Agreement shall
remain in effect until the later of (i) twelve months following the date of such
“Change-in-Control” or (ii) the date on which the Employee receives payment in
full of the severance compensation payable to Employee by the Company pursuant
to Section 2 of this Agreement.

    


    (b)           Notwithstanding
the above, the parties hereby agree that the Employee’s employment is “at-will”
and can be terminated by either party (with or without cause) at any
time.  The benefits provided hereunder shall be in addition to the
Employee’s annual salary, as determined by the Board of Directors of the
Company, and shall not (i) affect the right of the Employee to participate in
any current or future Company retirement plan or in any supplemental
compensation arrangement which constitutes a part of the Company’s regular
compensation structure, or (ii) be deemed salary or other compensation to the
Employee for the purpose of computing benefits to which the Employee may be
entitled under any retirement plan or other arrangement maintained by the
Company for the benefit of its employees.

    In the
event of the complete termination by the Company of Employee’s employment (as
contemplated under Code Section 409A)  within one year following a
“Change-in-Control” (as defined below) of the Company, the Company shall pay
Employee, within thirty (30) days of the termination of employment (subject to
Section 4 below), an amount equal to the average of the base salary paid to the
Employee for the three (3) preceding fiscal years (calculated by adding the base
salary paid for each of the three (3) preceding completed fiscal years and
dividing the sum by three (3), with the quotient equaling the amount to be
paid). All amounts
paid to the Employee under this Section shall be paid in twelve equal
installments over the twelve-month period commencing on the date of such
termination, shall be treated as additional compensation and the Company shall
have the right to deduct any taxes required by law to be withheld with respect
to such amounts.

              Definition
      of Change in Control

            


    

    


    As used
herein “Change-in-Control” means (a) a change in control as such term is
presently defined in Regulation 240.12b-2 under the Securities Exchange Act of
1934 ("Exchange Act"); or (b) if any “person” (as such term is used in Section
13(d) and 14(d) of the Exchange Act) (other than any “person” who on the date of
this Agreement is a director or officer of the Company), becomes the “beneficial
owner” (as defined in Rule 13(d)-3 under the Exchange Act), directly or
indirectly, of securities of the Company representing twenty (20%) percent of
the voting power of the Company’s then outstanding securities, as the case may
be, other than as a result of an acquisition of such securities from or by the
Company; or (c) if during any period of two (2) consecutive years during the
term of Employee's employment, individuals who at the beginning of such period
constitute the Board of Directors of the Company cease for any reason to
constitute at least a majority thereof.

    


    
      	
               
      

            	
              4.

            	
              Specified
      Employee

            


    

    


    In the
event the Employee is classified as a “Specified Employee” as of the date of
termination of employment, as such term is defined in Code Section 409A and the
regulations thereunder, and provided that the payment required pursuant to
Section 2 hereof is determined to be subject to Code Section 409A, then
notwithstanding the terms of Section 2, such payment shall commence on the first
day of the seventh month following the date of the Employee’s termination of
employment.
