                                   WITNESS:

     WHEREAS, the Company desires to retain Advisor as an independent contractor
to provide services for the Company on a nonexclusive basis; and

     WHEREAS, Advisor is willing to render such services to the Company on the
terms and conditions set forth in this Agreement.

     THEREFORE, it is agreed as follows:

     Section 1.  Duties and Term. The Company hereby engages Advisor, effective
as of the date hereof, as an advisor to provide services to the Company. The
goal of this agreement is to have Advisor work closely with the Company's
management team and its Board of Directors. Advisor and Timothy J. Kilgallon,
President & Chief Executive Officer of the Company, have had substantive
discussions about the Company and its immediate needs. Based on the
conversations, the parties have agreed that Advisor will provide services in the
following principle areas:

               (i)   Assistance and advice in the development, implementation
and ongoing refinement of: marketing plans; customer implementation; customer
service and support strategies; sales programs and activities; company
management and organization development.

               (ii)  Be a mentor and coach to the C.E.O. and President, along
with key senior managers, particularly Scott Wiley.

               (iii) Become a trusted advisor and confidant to senior
management.

               (iv)  Become a member of the Board of Directors and operate as a
"Lead Director" on Company operations and execution of effectiveness.

               (v)   Apply concentrated effort to assure the Company's
achievement of its Second Quarter 1999 Vital 5 Objectives.

     Advisor and the Company have projected that to provide services to meet the
responsibilities identified above, Mr. Davenport will have to commit to, at
minimum an average of eight (8) day(s) per month for the first ninety (90) days
of this Agreement. The time commitment by Advisor will begin April 5, 1999 and
continue until July 2, 1999, but may be increased or decreased upon the mutual
acceptance of both parties. Any increase or decrease in the time requirement of
Advisor may change the terms of compensation contained in "Section 2.
<PAGE>

Compensation." Mr. Davenport and Mrs. White have agreed that essentially Mr.
Davenport will have to be available on an "as needed basis" and therefore
readily available to assist the Company.

     Section 2.  Compensation.

          2.1  Fee Rate. Recognizing the early stage nature of the Company, its
               --------

Advisory will reduce his normal and customary fees of two thousand five hundred
dollars ($2,500) per day to five hundred dollars ($500) per day and receive a
stock or stock option grant(s) to offset this reduction and to provide an
incentive for Mr. Davenport to make significant contributions to the Company's
performance. Advisor will provide a monthly statement to the President and
C.B.O. detailing activities and services provided beginning with the month of
April, 1999. In satisfaction of the cash portion of the fee, the Company will
pay Advisor the sum of $4333.33 on or prior to the last day of each of the
months of April, May and June, 1999; provided Advisor continues to provide
services to the Company.

Directors) on the date of grant (currently estimated to be $0.125 per share).
This option will vest and become exercisable as follows: 16,666.66 shares will
vest on the last day of April, May, and June 1999 until fully vested; provided
Advisor continues to provide services to the Company.

involves products or services which could reasonably be determined to be
competitive with the products or services or proposed products or services of
the Company. If, however, Advisor decides to do so, Advisor agrees to notify the
Company in writing in advance (specifying the identity of the entity or the
person) and provide information sufficient to allow the Company to determine if
such consulting would conflict with projects or products of the Company. If the
Company determines that such business is in competition with that conducted by
the Company, this Agreement shall terminate immediately.
