Compensation Upon Early Termination
 (a)
    
    If Employee resigns during the term of this Agreement (without mutual consent
of Employer), or if this Agreement is terminated by Employer for cause, Employee shall
be entitled to all accrued but unpaid Base Salary and vacation pay accrued through the
date of delivery of the notice of termination, and all non-vested options shall be
deemed canceled as of that date.(b)
    
    If Employee is terminated without cause, as defined in subsection (i) through
(vii) of Section 5 above, Employer shall pay to Employee as liquidated damages and in
lieu of any and all other claims which Employee may have against Employer twelve (12)
months of Employees salary including amounts for medical benefits coverage under COBRA
commensurate with Employees coverage as of the date of termination. If Employees
contract is not renewed at the end of the term of this contract, Employee will receive
aforementioned monthly severance for up to twelve months or until employed elsewhere,
which ever comes first. Employers payment pursuant to this subparagraph shall fully
and completely discharge any and all obligations of Employer to Employee arising out of
or related to this Agreement and shall constitute liquidated damages in lieu of any and
all claims which Employee may have against Employer not including any obligation under
the workers compensation laws including Employers liability provisions.

 (c)
    
    If Employees employment is terminated as a result of death or total
disability, Employee shall be entitled to accrued but unpaid Base Salary to date of
termination. The date of termination shall be deemed the date of death or, in the
event of disability, the date Employee qualified for total disability payments under
Employers long-term disability plan.(d)
    
    If Employees employment is terminated or constructively terminated as a result
of a Change in Control of Employer, Employee shall be entitled to a lump-sum payment
equal to three times Employees Base Salary at the time. A Change in Control shall
mean an event involving one transaction or a related series of transactions in which
one of the following occurs: (i) Employer issues securities equal to 33% or more of
Employers issued and outstanding voting securities, determined as a single class, to
any individual, firm, partnership or other entity, including a group within the
meaning of Section 13(d)(3) of the Securities Exchange Act of 1934; (ii) Employer
issues securities equal to 33% or more of the
issued and outstanding common stock of Employer in connection with a merger,
consolidation or other business combination; (iii) Employer is acquired in a merger
or other business combination transaction in which Employer is not the surviving
company; or (iv) all or substantially all of Employers assets are sold or
transferred.
