Employee shall have failed during such thirty (30) day period to resume the
diligent performance of his duties.  If Employee, in good faith, disputes
Switchboard's determination that he has not so resumed the diligent performance
of his duties, the parties agree to submit such dispute to arbitration in

Switchboard, at the Employee's then current contribution rate for such benefits
for a period of up to six months commencing on the effective date of Employee's
termination (the "Continuation Period") in the event that the Employee remains
unemployed during the Continuation Period. If Employee obtains other employment
during the Continuation Period, any continuing benefits will cease.

     5.  Circumstances Triggering Receipt of Termination Benefits.
         --------------------------------------------------------

          5.1  Termination by Switchboard.  Switchboard shall provide the
               --------------------------
Employee with the benefits set forth in Section 6 upon termination by
Switchboard of the Employee's employment at any time during the term of this
Agreement for reasons other than termination for "cause."  For the purposes
hereof, "cause" shall be defined as the willful and repeated failure of the
Employee to perform substantially his duties, or action by the Employee
involving willful misfeasance, gross negligence or the commission of any
felonious action; provided, however, that termination for cause shall not be
effective unless the Employee shall have received written

                                      -5-
<PAGE>

notice from Switchboard of such failure (specifying in detail the facts and
circumstances on which Switchboard is relying) and a demand for substantial
performance thirty (30) days prior to such termination, and Switchboard
determines that the Employee shall have failed during such thirty (30) day
period to resume the diligent performance of his duties. If Employee, in good
faith, disputes Switchboard's determination that he has not so resumed the
diligent performance of his duties, the parties agree to submit such dispute to
arbitration in accordance with the provisions of Section 12 below.

          5.2  Termination by Employee.  Switchboard shall provide the Employee
               ------------------------
with the benefits set forth in Section 6 upon termination by the Employee of the
Employee's employment with Switchboard at any time during the term of this
Agreement if the Employee elects to resign within 90 days of either of the
following events:

               (i)  The Employee's job is relocated more than 35 miles from
     Westboro, Massachusetts; or

               (ii) The Employee's job title and/or overall targeted cash
     compensation are materially reduced from levels in effect at the
     commencement of the initial or any renewal term of this Agreement.

          5.3  Notice of Termination.  Any termination of the Employee's
               ---------------------
employment by Switchboard or by the Employee as referred to in this Section
shall be communicated by written notice of termination to the other party.

     6.   Termination Benefits.  Subject to and in accordance with the
          --------------------
provisions set forth in Section 5, and further subject to the execution of a
mutually agreeable release agreement, the following benefits (subject to any
applicable taxes required to be withheld) shall be paid to the

                                      -6-
<PAGE>

Employee as follows:

          (a) Compensation.  The Employee will be paid his base salary for a
              ------------
period of six months from the effective date of his termination (the
"Continuation Period"), in the event that the Employee remains unemployed during
the Continuation Period.  If the Employee obtains other employment during the
Continuation Period, any salary continuation will cease unless the Employee's
new employment is at a base salary lower than his base salary under Section 3.1,
in which case the Company will pay the Employee the difference between his base
salary under Section 3.1 and his new base salary during the Continuation Period.

          (b) Insurance Benefits, etc.  The Employee's participation (including
              ------------------------
dependent coverage) in the life, health and dental insurance plans (excluding
further participation in the existing 401K Plan) of Switchboard in effect
immediately prior to the effective date of Employee's termination shall be
continued, or equivalent benefits provided, by Switchboard, at the Employee's
then current contribution rate for such benefits for a period of up to six
months commencing on the effective date of Employee's termination in the event
that the Employee remains unemployed during the Continuation Period.  If
Employee obtains other employment during the Continuation Period, any continuing
benefits will cease.

     7.   Continuing Obligations.  In order to induce Switchboard to enter into
          ----------------------
this Agreement, the Employee hereby ratifies and confirms his Invention and Non-
Disclosure Agreement with Switchboard.  Without limiting the generality of the
foregoing, the Employee agrees that all documents, records, techniques, business
