      4. Voluntary Termination. In the event that Employee voluntarily resigns
from Employee's employment with the Company, or in the event that Employee's
employment terminates as a result of Employee's death or disability (meaning
that Employee is unable to perform Employee's duties for any 90 days in any
one-year period as a result of a physical and/or mental impairment), Employee
will be entitled to no compensation or benefits from the Company other than
those earned under Paragraph 3 through the date of Employee's termination.
Employee agrees that if Employee voluntarily terminates Employee's employment
with the Company for any reason, Employee will provide the Company with 30 days'

Employee's resignation at an earlier date.

      5. Other Termination. Employee employment may be terminated under the
circumstances set forth below.

            (a) Termination for Cause: If Employee's employment is terminated by
the Company for cause as defined below, Employee shall be entitled to no
compensation or benefits from the Company other than those earned under
Paragraph 3 through the date of Employee's termination for cause.

      For purposes of this Agreement, a termination "for cause" occurs if
Employee is terminated for any of the following reasons: (i) theft, dishonesty,
misconduct or falsification of any employment or Company records; (ii) improper
use or disclosure of the Company's confidential or proprietary information;
(iii) any action by Employee which has a material detrimental effect on the
Company's reputation or business; (iv) failure by the Employee to abide by the
policies of the Company (including, without limitation, policies relating to
confidentiality and reasonable workplace conduct); (v) Employee's failure or
inability to perform any assigned duties after written notice from the Company
to Employee of, and a reasonable opportunity to cure, such failure or inability;
or (vi) Employee's conviction (including any plea of guilty or no contest) for
any criminal act that impairs Employee's ability to perform Employee's duties
under this Agreement.

            (b) Termination Without Cause or For Good Reason: If Employee's
employment is terminated (i) by the Company without cause (and not as a result
of Employee's death or disability) or (ii) by Employee for "good reason", and if
Employee enters into a binding general release of known and unknown claims in a
form satisfactory to the Company, Employee will receive severance payments at
Employee's final base salary rate, less applicable withholding, and payment for
medical benefits provided by Company to Employee at time of termination until
the earlier of (A) twelve months or six months (as determined in accordance with
the next two sentences) after the date of Employee's termination without cause
or for good reason, or (B) the date on which Employee first commences other
employment. If Employee's employment is terminated by the Company without cause
(and not as a result of Employee's death or disability) then, for purposes of
determining twelve or six months in (A) of the prior sentence, the number of
months shall be twelve if such termination occurs within twelve months of your
hire date, and shall be six if such termination occurs after the anniversary of
your hire date. If Employee's employment is terminated by the Employee for good
reason, then, for purposes of determining twelve or six months in (A) of the
first sentence of this paragraph, the number of months shall be twelve.
Severance payments will be made in accordance with the Company's normal payroll
procedures. For purposes of this section "good reason" means any of the
following after a Change of Control occurs (i) the relocation without your
authorization of your place of work more than 80 miles from your principal place
of residence at 62 Countryside Drive, Cumberland, Rhode Island, or (ii) the
assignment to the Employee of duties inconsistent in any material respect with
the Employee's duties on the hire date which results in a material diminution in
such position.
