interest Consultant may have in Q-Flow or the Software, or Intellectual Property

whatsoever in or to any Company  product or technology and expressly  waives any

warranty and waiver herein collectively referred to as "Waiver").

4.       COMPENSATION:

         4.1 In consideration of the Assignment and Waiver,  Company shall issue
50,000 shares of Company's  Common Stock,  par value $.01 per share (the "Common
Stock") to  Consultant,  promptly after the execution of this  Agreement,  which
shares shall  constitute full and complete  compensation for such Assignment and
Waiver.  The issuance of the shares is subject to the  provisions of Section 4.7
hereof.

         4.2 In  consideration  of  Consultant's  performance of the Phase 1 and
Phase 2 Tasks, as set forth in the Statement of Work,  Company shall  compensate
Consultant on a time and materials  basis,  at the rates set forth in Exhibit B;
provided,  however, that the amounts specified in Exhibit B shall constitute the
maximum amount  Company shall be required to pay  Consultant for  performance of

writing.  At the option of Company,  the  compensation  payable pursuant to this
Section 4.2 may be paid in cash or by the  issuance  of shares of Common  Stock.
The value of the shares of Common Stock to be so issued shall be  determined  as
the  average of the  closing  price of the Common  Stock on the NASDAQ  National
Market for the five trading days immediately preceding the date on which Company
becomes  obligated to make such payment.  The issuance of such shares is subject
to the provisions of Sections 4.7 and 4.8 hereof.

         4.3 Company  shall also pay to  Consultant a ten percent  (10%) royalty
based upon Company's Net Sales of Q-Flow;  provided,  however, that such royalty
shall  only be  payable  with  respect  to sales made prior to the date of first
customer  shipment  of the  Phase  2  product,  upon  which  date  such  royalty
obligation shall automatically terminate.

         4.4 In  consideration  of  Consultant's  performance of the Maintenance
Services as set forth in Section 2.3,  Company shall pay Consultant a royalty of
three percent (3%) based upon Company's Net Sales of the Phase 2 product.

         4.5 "Net  Sales"  shall mean  payments  collected  by Company  from its
customers on account of sales of licenses for the Phase 1 or Phase 2 product, as
the case may be ("License Payments"),  less any sales, use, excise,  value-added
or similar taxes,  shipping  charges,  import duties,  customs fees,  discounts,
allowances,  and  returns  actually  made or  allowed  as  supported  by  credit
memoranda issued to customers.  The royalties owed Consultant hereunder shall be
calculated  on a  quarterly  calendar  basis and shall be  payable no later than
thirty (30) days  following the close of Company's  fiscal  quarter during which
such License Payments are received.  Concurrently with the payment of royalties,
Consultant  shall be provided with a summary  statement of the  transactions  on
which the royalties are based.

         4.6 Consultant shall not be entitled to receive any other  compensation
or any benefits from Company. Except as otherwise required by law, Company shall
not withhold any sums from payments made to  Consultant  for Social  Security or
other federal,  state or local tax  liabilities or  contributions,  and all such
withholdings,  liabilities,  and  contributions  shall  be  solely  Consultant's
responsibility.

         4.7 In  connection  with the  issuance  of shares  of  Common  Stock to
Consultant  pursuant to Section 4.1 and, if any, Section 4.2,  Consultant hereby
represents and warrants to, and agrees with, Company as follows:

<PAGE>

         (a) The Consultant has sufficient knowledge and experience in investing
in  companies  similar  to Company  so as to be able to  evaluate  the risks and
merits of the Consultant's  receipt of shares of Common Stock of Company and the
Consultant is able financially to bear the risks thereof.

         (b) The Consultant has had an opportunity to discuss Company's
business, management and financial affairs with the Company's management.

         (c) The shares of Common  Stock being  acquired by the  Consultant  are
being  acquired for the  Consultant's  own account for the purpose of investment
and not with a view to or for sale in connection with any distribution thereof.

         (d) The  Consultant  understands  that  (i) the  shares  have  not been
registered under the Securities Act by reason of their issuance in a transaction
exempt from the  registration  requirements  of the  Securities  Act of 1933, as
amended (the  "Securities  Act") pursuant to Section 4(2) thereof or Rule 505 or
506  promulgated  under  the  Securities  act,  (ii)  the  shares  must  be held
indefinitely  unless a subsequent  disposition  thereof is registered  under the
Securities  Act or is exempt  from such  registration  and (iii) the shares will
bear a legend to such effect.  With respect to the shares of Common Stock issued
pursuant to Section 4.1 hereof,  Consultant  hereby  further agrees that he will
not sell,  transfer,  pledge or  otherwise  dispose  of the  shares  (except  in
connection  with an  acquisition  of Company)  for a period of one year from the
date of issuance of the shares.

         4.8 Company agrees that promptly after a request from Consultant  after
the  issuance of shares,  if any,  pursuant to Section 4.2 hereof,  Company will
prepare and file with the  Securities  and Exchange  Commission  a  registration
statement  on Form  S-3 to  register  such  shares,  and the  Company  will  use
commercially  reasonable  efforts to have such registration  statement  declared
effective and to maintain the effectiveness of such registration statement for a
period of at least six months.

5.       NONDISCLOSURE AND TRADE SECRETS:

         5.1 During the term of this Agreement and in the course of Consultant's
performance  hereunder,  Consultant  may  receive  and  otherwise  be exposed to

--------------------------------------------------------------------------------
                                  Phase 1 Tasks
--------------------------------------------------------------------------------

Summary
To produce,  at a minimum, a functionally  equivalent web only based application
that has the same level of  functionality  as the current  version of  Q-Browser
(v1.03) and the Q-Flow Process Module (build 21). The following functionality is
also to be included in Phase 1:

     o        Ability to add/modify/view/delete call subjects to a call and to
              include call subject information, and scripting

     o        Include  a  "Universal  Field  Control  (UFC)"  object  which,  by
              manipulation    of   object    properties,    can   be   used   to
              add/modify/view/delete  data contained in any accessible  database
              table

     o        Ability to add/modify/view/delete call reference codes

     o        Ability to  add/modify/view/delete  call  comments in a read-only,
              full edit access and append only mode (object property selectable)

     o       Ability to add/modify/view/delete dual SLTs for a call.

     o       Ability to add/modify/view/delete call priorities

     o       Ability to add/modify/view/delete Allocation and/or Assignments
             including the ability for the application to set these
             automatically based on system defaults

     o       Ability to perform the call functions of (including the
             modification of the function's timer):

             1.       Respond to Call (SLT1 and SLT2)
             2.       Fix Call (SLT1 and SLT2), including the ability to add/
                      modify/view/delete call fix codes

     o       Ability to add/modify/view/delete inventory (client/logon/config/
             item) to a call, including the ability to perform QBE functions
             from  within the call. The ability to auto-select inventory based
             on a parent/child relationship is to be preserved.

     o       Ability to add/modify/view/delete the organization structure
             (including location and cost code) to a call

     o       Ability to search for, list and browse calls based on List, List+,
             and by the general QBE function.  When listing and browsing calls,
             the full use of system indicators must be used.

System security parameters should be sourced from within the Quetzal|SC database
and from object property settings.

The expected milestones for Phase 1 tasks are:

     o       October  30,  2000- All  functionality  listed  above  ready for
             beta trials
     o       November 30, 2000- All functionality listed above ready for general
             production release.
