                   A.  Executive  is the  founder  of the  Company  and has been
President and a director since its formation.

                  B.  The  directors  of  the  Company  consider  the  continued
services of its principal  executives to be in the best interests of the Company
and its  shareholders.  The  directors  of the  Company  desire  to  assure  the
continued  services of such  principal  executives on an objective and impartial

of the principal executives whose continued services are deemed essential to the
future performance of the Company.  The execution and delivery of this Agreement
provides the Company with  continuity in  Executive's  services and  Executive's
continued loyalty.

                  In  consideration  of the  premises  and  conditions  of  this
Agreement, the Company and Executive agree as follows:

                   1.  Employment.  The Company and Executive hereby confirm the
continued  employment  of  Executive  by the  Company  under  the  terms of this
Agreement.

presently by the Company's  Bylaws.  Executive  shall serve as a director of the
Company if so elected by the shareholders.

date hereof and shall continue until terminated by either party on not less than

<PAGE>

                            (b)  In  the   event   Executive's   employment   is
terminated by Executive  following the occurrence,  without  Executive's written
consent,  of one or more of the following events in anticipation of or following
a Change in Control:

                                     (i) Executive is assigned reduced duties or
responsibilities   that  are   inconsistent   with  his  position,   duties  and
responsibilities   immediately  prior  to  such  assignment,  or  his  reporting
responsibilities or titles in effect at such time are reduced;

                                     (ii)  Executive's  annual  base  salary  is
reduced; or

                                     (iii)   Executive  is   transferred   to  a
location  which is an  unreasonable  distance  from his current  principal  work
location or is required to engage in a substantially greater amount of travel on
Company business.

                   6.  Salary  Continuation.  Upon  occurrence  of any  Event of
Termination,  the Company will continue to pay Executive's annual base salary on
a  regular  monthly  basis  for a  period  ending  on the  first to occur of the
following:

                            (a) Two  years  following  the date of the  Event of
Termination; or

                            (b)  The   obtaining   by   Executive  of  permanent
full-time employment by any other employer;  provided, however, that Executive's
annual base salary shall continue to be paid until two years  following the date
of the Event of  Termination  to the extent that the salary paid to Executive in
the new  employment  is less than the annual base salary  received by  Executive
prior to the Event of Termination. Executive will promptly advise the Company of
the fact of such new employment. The salary to be paid shall be Executive's base
salary  in  effect  on the date of the  Event of  Termination,  but  before  any
reduction that resulted in an Event of Termination under Section 5.3(b)(ii). The
base salary shall not include any cash bonus, profit sharing, pension, incentive
bonus or any fringe benefits.

                   7.  Benefits  Upon  Death.  In  the  event  of the  death  or
disability  of Executive  prior to the payment to Executive of all amounts which
have become payable to Executive  during his lifetime,  the Company will pay all
such amounts to his personal  representative or the executor or administrator of
his estate in the event of death or to Executive or the guardian or  conservator
of Executive in the event of disability.

                   8.  Attorney  Fees.  The  Company  recognizes  the  disparate
economic  positions of the Company and Executive in legal  actions  arising from
disputes as to the  enforceability or interpretation of agreements such as this.
Accordingly, to the fullest extent that a court having jurisdiction will enforce
a unilateral agreement for the payment of a party's legal expenses, it is agreed
that in any suit or action  brought by Executive  under this  Agreement in which
Executive shall prevail,  the Company will pay the reasonable  attorney fees and
court costs incurred by Executive in the prosecution of such suit or action.
<PAGE>

                   9. Limitation on Benefits. The benefits provided to Executive
by Section 6 shall be payable to the Executive only once,  even though there may
be two or more events constituting an Event of Termination.

                   10. General Provisions.

                            (a) No right, benefit or interest hereunder shall be
subject to assignment,  anticipation,  alienation,  sale,  encumbrance,  charge,
pledge, hypothecation or set-off in respect of any claim, debt or obligation, or
to execution, attachment, levy or similar process.

                            (b) This  Agreement may not be amended,  modified or
canceled except by written agreement of the parties.

                            (c) No  provisions  of this  Agreement may be waived
except by writing signed by the party to be bound thereby.

                            (d) In the event  that any  provision  or portion of
this  Agreement  shall be  determined  to be  invalid or  unenforceable  for any
reason,  the remaining  provisions of this Agreement  shall remain in full force
and effect to the fullest extent permitted by law.

                            (e) This  Agreement  shall be binding upon and inure
to the benefit of Executive and his personal  representative  and Company in any
successor organization or organizations which shall succeed to substantially all
of  the  business  and  property  of  Company,   whether  by  means  of  merger,
consolidation, acquisition of substantially all of the assets or voting stock of
Company or otherwise, including by operation of law.

                            (f) This  Agreement  has been  made in and  shall be
governed and construed in accordance with the laws of the state of Oregon.

                       AMENDMENT TO EMPLOYMENT AGREEMENT




                  This document  amends the  Employment  Agreement  entered into
between JOHN TORTORICI  ("Tortorici") and INFORMEDICS,  INC.  (formerly known as
Western Star, Inc.) (the "Corporation")  dated October 15, 1988 (the "Employment
Agreement").

                  Effective  and  conditioned  upon the  filing of  Articles  of
Merger  providing  for  the  merger  of the  Corporation  into an  affiliate  of
Mediware, Inc. (the "Merger"), the Employment Agreement is amended as follows:

         1.       Continuation and Termination of Employment.

                  Tortorici  shall  continue  as the  President  and  CEO of the
Corporation until the effective date of the Merger,  and as a full-time employee
of the  Corporation,  but not as an officer  or  director,  for the  three-month
period  following  the closing of the Merger  transaction  at his existing  base
salary of $150,000 per year, payable at the Corporation's normal pay periods. At
the  conclusion of such  three-month  period,  Tortorici's  employment  with the
Corporation  shall  terminate  and he shall be paid his accrued  vacation as may
exist at that date, if any. Any unvested  stock options held by Tortorici  shall
become immediately vested upon execution of this Amendment.

         2.       Consulting Services.

                  For the two-year  period  commencing  with the  termination of
employment date (the  "Consulting  Period"),  Tortorici will provide  consulting
services to the Corporation on such matters as the Corporation may request. Such
services  shall be at times  convenient  to  Tortorici  and shall be arranged in
advance so as not to  interfere  with  Tortorici's  other  business  or personal
activities. During the two-year period of consulting services, Corporation shall
continue to provide at its cost coverage for Tortorici  under medical  insurance
plans of the Corporation as may exist from time to time.

         3.       Noncompete Covenant.

                  During the period from the effective date of the Merger to the
end of the  Consulting  Period,  Tortorici  covenants  that  he will  not,  as a
principal,  shareholder,  director, officer, employee or consultant, directly or
indirectly,  engage in any business in any way connected  with the sale of blood
banking  software  that is in any  way  competitive  with  the  business  of the
Corporation or any affiliate in any geographic  markets then being served by the
Corporation or any affiliate.

         4.       Payments by Corporation.

                  As  consideration  for Tortorici's  noncompete  covenant,  the
Corporation  shall pay  Tortorici  monthly  payments in the amount of  $8,333.33
commencing on the first day of the month  immediately  following the termination
of employment and continuing on the first day of each month  thereafter  through
and including the 24th month.

         5.       Deletion of Inapplicable Provisions.

                  Paragraphs  2  through  6 and  paragraph  9 of the  Employment
Agreement  are  deleted  in their  entirety.  The  remaining  paragraphs  of the
Employment Agreement remain applicable to the relationship of the parties.

         6.       Effective Date.

                  This Agreement  shall become  effective upon and shall have no
effect unless and until the Articles of Merger  referenced  above are filed with
the Secretary of State for the State of Oregon.

                  EXECUTED this 5th day of December, 1997.
