                             EMPLOYMENT AGREEMENT

THIS AGREEMENT, made and entered into effective the 1st day of October, 1996
and between Vicom, Incorporated ("Employer") and Marvin Frieman ("Employee").

WITNESSETH:

WHEREAS, Employer desires to employ in the capacity and on the terms and
conditions hereinafter set forth, and Employee has agreed to accept such
employment.

NOW THEREFORE, in consideration of the premises and the mutual promises
hereinafter contained, the parties hereto agree as follows:

     1.  EMPLOYMENT RELATIONSHIP.  Employer hereby employs Employee as an
officer of Employer. Employee accepts such employment and agrees to perform
such duties as may be reasonably requested by Employer, as directed by
Employer. Employee's job description is set forth in Exhibit A attached
hereto and incorporated herein.

     2.  TERMS OF EMPLOYMENT.  Subject to the provisions for termination
hereinafter set forth the term of this Agreement and the performance of
Employee's services shall be (5) years commencing October 1, 1996, unless
earlier terminated as provided in Paragraph 8 hereof.

     3.  COMPENSATION AND FRINGE BENEFITS.  For all services rendered by
Employee to Employer in any capacity, Employee shall be compensated in
accordance with the terms set forth in this Section and in Exhibit B which is
attached hereto and made a part hereof. Employee shall be entitled to
participate in and to be covered by a profit-sharing, pension, life
insurance, accident insurance, health insurance, hospitalization and any
other employee benefit plan effective with respect to employees of Employer
only to the extent he/she shall be eligible and qualify under the terms of
such plans.

Company shall furnish Employee a late model automobile acceptable to
Employee, and Company shall pay all of Employee's business related
automotive expenses, specifically, but not limited to gasoline, insurance,
maintenance, and repairs.

A.  SPECIAL COMPENSATION.  Upon a change in control of Vicom, Inc. and

employee for reasons other than those defined in Section 8 hereof, employer
shall pay employees special compensation.

<PAGE>

"A change in control" shall mean the acquisition by any corporation or group
of associated persons acting in concert, excluding affiliates, if any, of
Vicom, Inc. and of the date hereof, of an aggregate of more than 20 percent
of the outstanding shares of voting stock of Vicom, Inc. coupled with or
followed by the election as directors of Vicom, of persons who were not
directors at the time of such acquisition, if such persons shall become a
majority of the Board of Directors of Vicom, Inc. "Voluntary termination by
employee" means that if employee determines in good faith that his/her status
or responsibilities has or have diminished subsequent to a change in control,
and if employee for that reason resigns from his/her employment within two
years after a change in control, then employee shall be entitled to receive
all the compensation and benefits listed in this Section and in Exhibit B.
"Special compensation" is defined as Employer's payment to Employee
immediately upon employee's written demand, of a lump sum amount equal to two
and one-half times the highest annual base salary paid or payable by Employer
to Employee for the three calendar years ending with the year of such
termination.

business of the Employer only when authorized by the CEO or other executive

expenses to be incurred which exceed $1,000.00 require verbal or written
pre-approval by both the CEO and the CFO. Employee agrees to re-pay or

shall reimburse the Employee for Employee's travel expenses, where such
travel is authorized or required by Employer.

and Employee hereby acknowledge that there are not Agreements or
understandings of any nature, oral or written, regarding Employee's
employment, apart from this Agreement.
