                             EMPLOYMENT AGREEMENT


     THIS AGREEMENT, by and between Patrick K. Brady (the "Employee") and
Teledata Solutions, Inc., an Illinois corporation (the "Company"), is made as of
March 19, 1996.

     In consideration of the mutual covenants herein contained, and in
consideration of the employment of Employee by the Company, the parties agree as
follows:

     1.   Duties and Scope of Employment.
          ------------------------------

     (a)  Position.  The Company agrees to employ the Employee under the terms
          --------
of this Agreement in the position of Chairman and Chief Executive Officer.
Employee shall report to the Board of Directors of the Company.

     (b)  Obligations.  During the term of this Agreement, the employee shall
          -----------
devote his full business efforts and time to the Company.

     (c)  Director.  As long as the Employee serves as Chief Executive Officer
          --------
or Chairman, Employee shall be nominated to serve on the Company's Board of
Directors.

     2.   Compensation.
          ------------

     (a)  Base Salary and Bonus.  Beginning on the effective date of this
          ---------------------
Agreement, the Employee shall be paid a base salary (the "Base Compensation) of
$90,000, per year, payable in accordance with the Company's standard payroll
policies. The Board of Directors shall review Employee's performance and the
Company's financial and operating results on at least an annual basis and shall
adjust Employee's base salary as it deems appropriate based on such review.

     (b)  Bonus.  Employee shall also be eligible for a bonus of up to $35,000
          -----
for fiscal year 1996 based on the criteria set forth in Exhibit A. The bonus
will be due and payable on the 15th day of February, 1997. The Board of
Directors shall set bonus levels and targets for years after fiscal year 1996 as
it deems appropriate. In the event Employee's employment with the Company
terminates for any reason other than pursuant to Section 6(c) hereof (voluntary
termination by the Employee) or 6(b)(ii) hereof (Termination for Cause),
Employee shall be entitled to receive a pro rated bonus for such year,
determined by dividing the aggregate bonus which he would have earned for the
entire year (assuming he had remained employed for the entire year and the
original revenue/milestone targets established for such year continued to apply)
by the number of full or partial months during which he was employed by the
Company. Such bonus shall be paid on February 15 of the following year. If
Employee's employment with the Company terminates pursuant to Section 6(c)
hereof or Section 6(b)(ii) hereof, Employee shall be deemed to have forfeited
his entire bonus for such year and no such bonus shall be due or payable by the
Company.

     (c)  Vacation.  Employee shall be entitled to three (3) weeks paid vacation
          --------
during each year of employment. Such vacation shall be taken at a time mutually
convenient for both the Company and the Employee. Unused vacation time may not
be accrued from year to year during
<PAGE>

the term of this Agreement without the Company's prior written approval. In the
event this Agreement is terminated by either the Company or the Employee, the
Employee shall be paid for any unused, accrued vacation time.

     3.   Definitions.  As used herein, the following definitions shall apply:
          -----------

     (a)  "Cause" shall mean the termination of employment of Employee shall
have taken place as a result of (i) act or acts of dishonesty undertaken by
Employee and intended to result in substantial gain or personal enrichment of
Employee at the expense of the Company, (ii) persistent failure by Employee to
perform the duties and obligations of Employee's employment which are not
remedied in a reasonable period of time after receipt of written notice from the
Company; (iii) the conviction of Employee of a felony; or (iv) Employee's
continued breach of any term of this Agreement or any Exhibit to this Agreement
after written notice and a reasonable period to cure.

     (b)  "Constructive Termination" shall mean (i) a material reduction in
Employee's salary or benefits not agreed to by Employee (except in connection
with a decrease to be applied because the Company's performance has decreased
and which is also applied to other officers, and excluding the substitution of
substantially equivalent compensation and benefits), or (ii) a material change
in Employee's responsibilities (other than as contemplated by, and consistent
with the spirit of, Section l(a)) not agreed to by Employee.

     (c)  "Disability" shall mean that the Employee, at the time notice is
given, has been unable to perform his duties under this Agreement for a period
of not less than six (6) consecutive months or for a period of two hundred
seventy (270) days in any three hundred sixty-five (365) day period as the
result of his incapacity due to physical or mental illness. In the event that
the Employee resumes the performance of substantially all of his duties
hereunder before the termination of his employment under Section 6(b) (iii)
become effective, the notice of termination shall automatically be deemed to
have been revoked.

     (d)  "Voluntary Termination of Employment" shall mean Employee voluntarily
terminates his employment with the Company, unless such termination occurs
within three (3) months following a Constructive Termination.

     4.   Employee Benefits.

     (d)  Waiver of Notice.  Any waiver of notice shall be valid only if
          ----------------
it is made in writing and expressly refers to the applicable notice requirement

     7.   Payments Upon Termination of Employment.
          ---------------------------------------

     (a)  Payments Upon Termination Pursuant to Section 6(b)(i) and
          ----------------------------------------------------------
Constructive Termination.  If, during the term of this Agreement, the Employee's
------------------------
employment is terminated by the Company pursuant to Section 6(b)(i) or
voluntarily by Employee within three (3) months following a Constructive
Termination, the Employee shall be entitled to receive the following:

          (i)  Severance Payment.  (A) The Company shall continue to pay to the
               -----------------
     Employee his Base Compensation for six (6) months following the date of
     Employee's actual termination of employment (together with amounts payable
     pursuant to (B) below, the "Severance Payment"). Such Base Compensation

                                      -3-
<PAGE>

     amount shall be the Base Compensation determined as of the commencement
     date of this Agreement, and as is agreed to in future years by the Board of
     Directors.

               (B)  The Employee shall have no duty to mitigate damages by
     attempting to secure new employment after termination of employment.
     However, in the event that the Employee does use his best efforts to secure
     equal or better employment than the employment hereunder after termination
     of employment from the Company and has not secured such new employment on
     the date six (6) months following Employee's termination of employment,
     then the Company shall continue to pay to the Employee the Base
     Compensation payable pursuant to (A) above for so long as the Employee
     continues to use his best efforts to secure such new employment, up to a
     maximum of an additional six (6) months. Notwithstanding anything herein or
     in Employee's Noncompetition, Nondisclosure and Developments Agreement of
     even date herewith to the contrary, the six-month time period set forth in
     paragraph 1 of the Employee's Noncompetition, Nondisclosure and
     Developments Agreement shall be extended by the amount of time that the
     Employee receives such additional Severance Payment.

          (ii)  Method of Payment.  The Severance Payment shall be made in
                -----------------
     monthly installments.

          (iii) Payment in Lieu of Contract Damages.  The Severance Payment
                -----------------------------------
     shall be in lieu of any further payments to the Employee and any further
     accrual of benefits with respect to periods subsequent to the date of the
     employment termination. Notwithstanding the preceding sentence, neither the
     Severance Payment nor any other payments under this Section 7(a) shall
     reduce or offset any benefits the Employee may be entitled to under the
     specific terms of the benefit plans of the Company.

     (b)  Termination By Company for Cause or Voluntary Termination.  If the
          ---------------------------------------------------------
Employee's employment is terminated pursuant to Section 6(b)(ii) or voluntarily
(other than within three (3) months following a Constructive Termination)
pursuant to Section 6(c), no compensation or payments will be paid or provided
to the Employee for the periods following the date when such a termination of
employment is effective. Notwithstanding the preceding sentence, the Employee's
rights under the benefit plans shall be determined under the provisions of those
plans.

     (c)  Termination on Death or Disability.  If the Employee's employment
          ----------------------------------
is terminated because of Employee's Death or Disability (as defined in Section
3(d) herein), then Employee shall receive other severance and disability
payments as provided in the Company's standard benefit plans.

          ----------------------------------------------
