Treasurer and Chief Financial Officer of the Corporation, and he agrees to
perform the duties normally incidental to these offices for as long as he holds

duties and responsibilities as may be prescribed from time to time by the Board.

     6.   Extent of Service.  The Employee shall devote his full time, attention
          -----------------

industriously, and to the best of his ability perform all of the duties that may
be required of him as an Employee.  The Employee shall not directly or

     7.   Disclosures of Information.  The Employee recognizes and acknowledges
          --------------------------

(as hereinafter defined) and that

                                       2
<PAGE>
 
such information constitutes valuable, special and unique property of the
Corporation.  The Employee will not, during or after the term of his employment,
directly or indirectly divulge, disclose or otherwise communicate or make
available any of such Confidential Information to any person, firm, corporation,
association, or other entity for any reason or purpose whatsoever without the
prior written consent of the Corporation.  Confidential Information includes
without limitation each of the following with respect to the Corporation: (i)
financial information; (ii) information concerning marketing plans or
strategies; (iii) information concerning customers, equipment suppliers and
other vendors; (iv) demographic information concerning the Corporation's markets
and potential markets; (v) information concerning business methods and
practices; and (vi) any other information which the Corporation treats as
confidential.  Confidential Information shall also include without limitation
any information or materials received by the Corporation from third parties in
confidence (or subject to nondisclosure or similar agreements).  The Employee
should consider all information coming into his possession by virtue of his
employment relationship with the Corporation to be Confidential Information
unless it is freely available to the public.

     8.   Materials.  All data, listings, charts, drawings, records, documents,
          ---------                                                            
programs, software, documentation, memoranda, journals, notebooks, records,
files, drafts, specifications and similar items relating to the business of the

customers, whether compiled by the Employee, furnished to the Employee by the
Corporation, its customers or clients or otherwise made accessible to the
Employee or coming into his possession, while the Employee is in the employ of
the Corporation, and copies of any such items, shall be and remain the sole and
exclusive property of the Corporation or its customers or clients, as the case
may be, and none of such items shall be removed from the Corporation's business
premises by the Employee without the prior consent of the Corporation, except as
required in the course of his employment.  All of such items shall be returned
to the Corporation by the Employee upon the termination of his employment with
the Corporation for whatever reason.  The provisions of this Section 8 shall
not, however, prohibit the Employee from using any materials published by the
Corporation and made available (without breach of this Section) to the general
public.

     9.   Termination.
          ----------- 

          (a) Death or Disability.  In the event of the Employee's death or in
              -------------------                                             
the event of his disability for a period in excess of one (1) month during the
term of this Agreement, the Corporation (i) shall pay to the Employee or to his
heirs or personal representatives the amount of compensation accrued under
Section 3 hereof through the date of death or (in case of disability) through
the end of the one-month period commencing with the onset of disability and (ii)
shall make any other payment required under Section 9(e) of this Agreement.  The
Corporation shall thereafter

                                       4
<PAGE>
 
have no further liability under this Agreement to the Employee or his heirs or
personal representatives.  "Disability" for purposes hereof shall be deemed to
have occurred if the Employee because of injury or sickness is unable to perform
each of the material duties of his occupation.  In the event of any dispute as
to whether the Employee is disabled, the determination of the Board shall be
final and binding.

          (b) Termination with Cause by the Corporation.  At any time during the
              -----------------------------------------                         
term hereof, the Corporation shall have the right to terminate for cause the
Employee's employment under this Agreement upon the occurrence of any of the
following events by the Employee:

               (i)  persistent neglect of his duties hereunder or a willful
     violation of any of the provisions of this Agreement or any other
     arrangement with the Corporation, which continues after written notice and
     ten (10) days in which to cure;

              (ii)  dishonesty, fraud, embezzlement, defalcation, or conviction
     of any felonious offense; or

             (iii)  intentionally imparting Confidential Information, as defined
     in Section 7, to competitors or to other third parties other than in the
     course of carrying out his corporate duties.

Such termination shall be effective immediately upon the delivery to the
Employee by the Corporation of written notice of such termination.  In the event
of a termination of the Employee's employment for cause in accordance with the
provisions of this Section 9(b), the Corporation shall pay to the Employee on
the date of termination all compensation accrued under Section 3 of this

                                       5

Agreement to the date of such termination.  Thereafter, the Corporation shall
have no further obligation to the Employee.

     10.  No Termination Without Cause by the Corporation.  The Corporation
          -----------------------------------------------                  
shall not be entitled to terminate the Employee's employment during either the
initial or any renewal term hereof without cause.  The Corporation may, however,
with or without cause, suspend the performance of the Employee's duties
hereunder, such suspension to be effective immediately upon written notification
by the Corporation to the Employee.  In such event, the Employee shall continue
to be an employee of the Corporation through the conclusion of the initial or
renewal term during which suspension of duties occurs, and the Employee shall be
entitled during such initial or renewal term to receive all compensation and
benefits provided for herein, including any benefits related to the vesting of
options pursuant to the Stock Option Agreement to which the Employee is a party.

     11.  Notices.  Any notice required or permitted to be given under this
          -------

notice to the other.  Such notice shall be effective as of the date received or
(if mailed as described above) the date of mailing.

     12.  Assignment.  This Agreement may not be assigned by either party hereto
          ----------                                                            
without the consent of the other party.  Subject to the foregoing, the rights
and obligations of the Corporation under this Agreement shall inure to the
benefit of and shall be binding upon the successors and assigns of the

          (d) Whenever possible, each provision of this Agreement will be
interpreted in such a manner as to be effective and valid under applicable law,
but if any provision of this Agreement, or the application thereof to any party
hereto or under any circumstances, shall be invalid or unenforceable to any

party in seeking any of such remedies.
