Mr. Richard Brown
Hamilton Lodge
Dean Lane
Cookham Dean, Berkshire SL6 9AF
United Kingdom

Dear Richard:

Over the last several months we have spent a great deal of time evaluating our
plans to launch into the international marketplace. After careful evaluation by
the management team it has been determined that we are willing, financially
capable, and have a product that is ready with minimal entry level changes
required. Furthermore, the international market for a standards based call
center product with rich CTI functionality appears to be potentially more robust
than the US.

This immediate market opportunity has focused our attention on recruiting an
experienced, high energy individual that will be able to both plan for and
exploit this opportunity. After our initial meeting and your subsequent visit to
our corporate facility, the management team is in unanimous agreement that you
fit this profile.

I am pleased to extend this invitation to you to join Teledata Solutions, Inc.
in the capacity of Director International Operations, reporting to me.

Your objectives will include:

  .  Develop a plan to exploit the International marketplace. The initial focus
     will be on Europe and anticipate we will move to Asia Pacific in the near
     future. The plan you develop will determine the best business model which
     will be primarily focused on product distribution and support strategies,

  .  Provide Product Marketing with focused input regarding the special product,
     literature, trade show, home page, and other unique requirements of your
     marketplace,

  .  Work with Finance in setting up the optimal business structure,

  .  Develop a hiring plan that brings the appropriate staff in when required to
     sell and support our systems in line with the distribution methods
     selected,

  .  Virtually any other task that is required to create a world class call
     center solution company.

Your compensation package will consist of an annual base salary of
(pound)67,000. In addition, a bonus package will be provided with an annualized
target of (pound)24,000 paid quarterly which will consist of a set of mutually
agreed upon MBOs. This bonus will transition to a plan based 50% on MBOs and 50%
on financial performance such as revenue, bookings, and/or margin contribution
in 1998. This will result in a targeted annual compensation of (pound)91,000. In
addition you will be granted an incentive stock option (ISO) for 20,000 shares
of Teledata stock. The ISO has a standard twelve month probation period after
which on the first anniversary date, you will vest the first twelve (12) months
and accrue 1/48 of the total option each month thereafter until the option is
fully vested at four years.

You will be provided with a benefit plan which includes health insurance for you
and your dependents, life insurance at 3 times your annual salary, annual
pension contribution of 5%, and permanent health insurance.

You will be provided with (pound)12,500 towards your own vehicle with mileage
reimbursed at 30-40 pence per mile.

You will be required to sign a statement agreeing to hold the company's
proprietary information confidential during and after your employment.

Richard, I am sincerely looking forward to working with you in building from the
ground up the best designed and performing international operation for an
American software firm in the industry. We have the foundation in place with our
current products and set of partners to aggressively launch this endeavor. The
window of opportunity is wide open for all of us to exploit this opportunity.

While the offer we are providing provides some obvious financial rewards, I
truly believe that the greater opportunity for you is to build something from
scratch that has your name on it. The entire management team at Teledata will do
whatever is necessary to make you and your efforts a success. I personally
believe in you and the opportunity and am committed to making this an exceeds
expectations situation for all involved.

This offer will remain open for 7 days from the date of this letter. Should you
decide to join Teledata, I would appreciate you signing and returning one copy
of this letter to me.

Sincerely,

James M. Nelson
Vice President Sales

or discharged unless the modification, waiver or discharge is agreed to in
writing and signed by the Employee and by the President. No waiver by either
party of any breach of, or of compliance with, any condition or provision of
this Agreement by the other party shall be considered a waiver of any other
condition or provision or of the same condition or provision at another time.

          (b) Whole Agreement.  No agreements, representations or understandings
(whether oral or written and whether express or implied) which are not expressly
set forth in this  Agreement or the Exhibits hereto have been made or entered
into by either party with respect to the  subject matter hereof.  This Agreement
shall supersede and control in the event of any conflict between this Agreement
and any other correspondence with the Company.

          (c)  Choice of Law.  This Agreement shall be governed by and construed
in accordance with the internal laws of the State of Illinois.  Any claims or
legal actions by one party against the other arising out of the relationship
between the parties contemplated herein (whether or not arising under this
Agreement) shall be governed by the laws of the State of Illinois and shall be
commenced and maintained in any state or federal court located in Cook County,
Illinois, and both parties hereby submit to the jurisdiction and venue of any
such court.

          (d)  Severability. The invalidity or unenforceability of any provision

damages, awards, or compensation other than as provided by this Agreement.

          (g)  Employment Taxes.  All payments made pursuant to this Agreement
will be subject to withholding of applicable taxes.
