1.   CERNER'S LETTER OFFERING EMPLOYMENT TO YOU.
     ------------------------------------------

     The  position, terms, compensation, benefits and  other
     provisions   of   your  offer  letter   represent   the
     conditions of your Cerner employment.  The offer letter
     is  incorporated into this Agreement as  Attachment  I.
     Cerner  reserves  the right to modify  at  anytime  the
     conditions of your employment by Cerner.

2.   EMPLOYMENT RELATIONSHIP.
     -----------------------

         A.   Formation.
              ---------    By  signing this  Agreement,  you
              represent  that  every material fact contained
              in your resume and  application for employment
              with Cerner  is  true and accurate to the best
              of  your knowledge and belief.  You also agree
              that   falsification   of   your   resume   or
              application    is    grounds   for   immediate
              discharge.

         B.   Type.
              ----    To the extent permitted by  law,  your
              employment  relationship  with  Cerner  is "at
              will", which  means  that  you may resign from
              Cerner at  any time, for any reason, or for no
              reason  at  all,  and  without  advance notice
              (except as described  below).  It  also  means
              that  Cerner  may  terminate  your  employment
              at any time, for any legally permitted reason,
              or for no reason at all, and   without advance
              notice.

         C.   Resignation  and Termination.
              ----------------------------    You  agree  to
              cooperate with Cerner  by  participating fully
              in  an  exit  interview in the event you leave
              the employ of Cerner. You agree to give Cerner
              written  notice  of  your  intention to resign
              from employment at  least twenty (20) business
              days prior to the last day you intend to  work
              at  Cerner.   To  facilitate the provisions of
              paragraphs 7 and 8 of this agreement, you also
              agree to report to Cerner, in conjunction with
              your written notice of intent, the identity of
              your  new  employer (if any) and the nature of
              your  proposed   duties   for  that  employer.
              Cerner, however,  reserves the right either to
              accelerate your intended effective termination
              date to an earlier  actual  date  or to  allow
              your  intended  effective  termination date to
              stand.

              If you resign, however, with fewer than twenty
              (20) business  days notice, or if you actually
              leave  Cerner's  employ  prior  to  expiration
              of the  twenty business days notice period and
              without   the   permission of Cerner, then you
              agree that  (to the extent

_/s/JRC_____________
Associate's Initials


              permitted  by   law)   no    salary  or  other
              compensation otherwise due,   from the date of
              your resignation notice until the time of your
              approved  effective termination date,  will be
              owed or paid to  you   by  Cerner.  Failure to
              provide a four week notice period  may  affect
              your future rehire ability with Cerner.

              If  Cerner  terminates  your  employment  (and
              unless  the   termination  was  due  to   your
              dishonesty,  illegal  conduct,  or  breach  of
              Cerner's  policy  or  this  Agreement), Cerner
              will   pay   you   in  conjunction  with  such
              termination  the  equivalent  of  $10,000  per
              month  for  the  remaining  period   of   your
              employment  contract  which   expires   twenty
              months   after  the   Cerner   acquisition  of
              Citation is  completed. Further  more,  Cerner
              agrees  that  you  will be elgibile to receive
              COBRA benefits for a perio  of eighteen months
              after termination or until October 31, 2003 at
              your cost and election.  You acknowledge  that
              the  consideration for the increased severance
              benefit  beyond  Cerner's  standard  severance
              benefit  is  the  termination  by  you  of the
              Severance Benefit in  the Event of Termination
              of  Your  Employment  with  Citation  Computer
              Systems,  Inc.  under   Certain  Circumstances
              Following a Change of Control entered into  by
              and between you and Citation Computer Systems,
              Inc.   dated   as   of  July   15,  1999.   By
              signing this agreement, you agree  that   such
              agreement    is    terminated,   and   of   no
              further force and effect. You agree to execute
              such  further  documents  as may be reasonably
              requested   by    Cerner  to  effectuate  such
              termination.

              In   the    event   Cerner   terminates   your
              employment,  Cerner  reserves the right to set
              the effective date of  such termination.  Upon
              your resignation or  the termination  of  your
              employment,  you   agree  to promptly  execute
              a  Termination  Statement   in   the  form  of
              Attachment III.

     -----------

     You   agree   that  you  will  forever   maintain   the
     confidentiality of Confidential Information.  You  will
     never  disclose  Confidential  Information  except   to
     persons  who have both the right and need to  know  it,
     and  then  only  for the purpose and in the  course  of
     performing Cerner duties, or of permitting or assisting
     in  the authorized use of Cerner products and services.
     In  the  event  your employment with Cerner  terminates
     (voluntarily  or  involuntarily),  you  will   promptly

     including  any Confidential Information on any  laptop,

     full-time responsibility.  As a part-time associate, it
     is  Cerner's  expectation that you will not  engage  in
     other employment activities that would detract from  or
     conflict  with your ability to carry out your part-time
     duties at Cerner.

5.   NEW PRODUCTS AND IDEAS.
     ----------------------

     With  respect  to  New  Products  and  Ideas  that  you
     develop, author, or conceive in whole or in part  while
     employed  at Cerner, plus for one year thereafter,  you
     agree to keep accurate, complete and timely records  of
     such New Products and Ideas, and will promptly disclose
     and  fully  describe  such New Products  and  Ideas  in
     writing  to Cerner.  You further agree to maintain  all
     information  respecting any New Products and  Ideas  as

     any  party  outside  of  Cerner  without  the  express
     written approval of an officer of Cerner.

     You  agree  to  assign and transfer to Cerner,  without
     further  consideration, your entire  right,  title  and
     interest  in  and  to all such New Products  and  Ideas
     including  any patents, copyrights, trade  secrets  and
     other  proprietary rights in the same.  You  waive  any
     and all moral rights which you otherwise would have  in

     written  assignment of title to Cerner, and all letters
     (and applications for letters) of patent and copyright,
     in  all  countries,  for  any  New  Products  or  Ideas
     required  to be assigned by this Agreement.   You  also
     agree   to  assist  Cerner  or  its  nominee  in  every
     reasonable way (at Cerner's request and expense, but at
     no  charge to Cerner), both during and after your  time
     of employment at Cerner, in vesting and defending title
     to the New Products and Ideas in and for Cerner, in any
     and   all  countries,  including  the  obtainment   and
     preservation of patents, copyrights, trade secrets  and
     other proprietary rights.

     This  Section  does not apply to your new products  and
     ideas  which do not relate directly to the business  of
     Cerner,  and which are developed entirely on  your  own
     time.   You acknowledge that this provision applies  to
     all products and ideas which relate to the business  of
     Citation  Computer  Systems, Inc. that  were  developed
     during  your employment with Citation Computer Systems,
     Inc..

7.   NON-COMPETITION AND NON-SOLICITATION
     ------------------------------------

     For  a  period of two (2) years after the voluntary  or
     involuntary termination of your employment with Cerner:

         A.   You  will  tell any prospective new  employer,
              prior  to  accepting  employment   that   this
              Employment Agreement exists.

         B.   If  you  have  worked for Cerner  in  a  sales
              capacity,  you  will not provide  services  to
              any  Conflicting   Organization in  connection
              with the marketing, sale  or promotion of  any
              Conflicting Product:

                 (1)  to  any  person  or  organization upon
                      whom you called or whose account   you
                      supervised  on  behalf  of  Cerner any
                      time during the last three  (3)  years
                      of your employment by Cerner, and

                 (2)  within  any  Cerner   sales  territory
                      assigned to you during the last  three
                      (3) years of your employment by Cerner.

         C.   If  you have not worked for Cerner in a  sales
              capacity during the last three years  of  your
              employment  by  Cerner,  you  will not provide
              services  directly  or  indirectly  related to
              your  employment at  Cerner to any Conflicting
              Organization  in  the  United States or in any
              country  in  which  Cerner   has   a  business
              interest.   However  you may accept employment
              with  a large Conflicting  Organization  whose
              business is diversified, and with a portion of
              its   business  that  is  not  a   Conflicting
              Organization,  provided that Cerner, prior  to
              your acceptance   of  such  employment,  shall
              receive     separate     written    assurances
              satisfactory to Cerner from  such  Conflicting

_/s/JRC_____________                 3
Associate's Initials




              Organization and  from  you that you will  not
              render  services  directly  or  indirectly  in
              connection  with  any  Conflicting Product.

        D.    Notwithstanding    the   foregoing,    nothing
              contained in  this Paragraph 7 shall  prohibit
              you (after your termination of employment with
              Cerner) from taking a  position with a general
              consulting organization whose only Conflicting
              Product   is   the  provision  of   consulting
              services to the  healthcare industry,  so long
              as you personally do not  thereby provide   or
              assist in providing consulting  services to  a
              Client  with  respect to any  Cerner  product,
              process or service or any Conflicting Product.

     E.       You  agree  not, on  behalf  of yourself or on
              behalf  of  any   other   person,  entity,  or
              organization,   to    employ,    solicit   for
              employment, or  otherwise  seek  to employ  or
              retain any Cerner associate or employee,    or
              any employee of a Cerner client company, or in
              any   way   assist  or  facilitate  any   such
              employment, solicitation, or retention effort.

8.   POST-TERMINATION PAYMENTS BY CERNER.
     -----------------------------------

         If  you  are  unable  to  obtain  employment within
         three   (3)  months  after  termination   of   your
         employment  at  Cerner  due  solely  to  the   non-
         competition   restrictions  imposed   on   you   by
         Paragraph  7  of this Agreement, the  provision  of
         Paragraph 7 shall continue to bind you only so long
         as  Cerner  shall  make  to  you  monthly  payments
         equivalent, on an annualized basis, to your average
         earnings during the last three years of your Cerner
         employment (or of your average Cerner earnings,  if
         you  were  employed fewer than 3 years),  for  each
         month of such unemployment.

         You   will,   during   each   month    of      such
         unemployment,  make  conscientious  and  aggressive
         efforts to find employment.  You will also,  within
         ten days after the end of each calendar month, give
         Cerner  a detailed written account of your  efforts
         to  obtain  employment.  In  your  monthly  written
         account,   you   will  identify  each   Conflicting
         Organization with which you have sought employment.

         Cerner   shall,  at  Cerner's  option,  be relieved
         of  making  a monthly payment to you for any  month
         during   which   you   fail  to   seek   employment
         conscientiously and aggressively, and to account to
         Cerner as described above.

         Cerner  is  obligated  to  make  such  payments  to
         you  upon  your  fulfillment of the conditions  set
         forth  above  beginning in the 4th  month  of  your
         unemployment  and  continuing  for  the   following
         twenty (20) consecutive months (for a total  of  21
         monthly payments), unless Cerner gives you:

         A.  Written    permission   to   accept   available
             employment, or

         B.  A  written  release  from  the  non-competition
             obligations   set  forth in Paragraph 7 of this
             Agreement.

9.   PUBLICITY RELEASE.
     -----------------

     You  consent  and agree to the use of your name,  voice
     and  picture (including but not limited to use in still
     photographs,  videotape  and  film  formats,  and  both

     newspapers, brochures, magazines, journals and films or
     videotapes) by Cerner.

10.  CERNER PROPERTY.

     equipment  is  issued,  you will  formally  acknowledge
     receipt  of it and will take all reasonable precautions

     Cerner.   You  further agree that Cerner  may,  at  its
     discretion,  deduct  from your  paycheck(s),  including

     immediately returned to Cerner upon your termination of

J. Robert Copper
28 West Brentmoor Place
Clayton, MO  63105

Dear Bob:

Under  your  leadership over the past 5 years,  Citation  has  created
significant value as a recognized brand in the laboratory  market.  We
expect  this brand and the product behind it to be valuable  additions
to  Cerner's enterprise-wide suite of HIS solutions. The value of  the
Citation business, and the synergies with Cerner's solutions have been
validated  by  our  due diligence process. Pending completion  of  the
proposed  Cerner/Citation  transaction, we  look  forward  to  joining
forces  as  we  position  our combined companies  to  make  healthcare
smarter. Your leadership throughout the coming months will be critical
to the long-term success of this partnership.

While  we  understand  that  it is your  intent  to  retire  upon  the
completion  of  the  merger  transaction, we  believe  your  continued
involvement  will be important as we capitalize on  a  unique  set  of
clinical  offerings to the laboratory marketplace.  As  a  result,  we
would like to retain you in an advisory capacity after the transaction
closes.  We  believe that your expertise with Citation's business  and
clients  will be important to making an effective transition over  the
coming months.

TERMS OF POSITION
- -----------------

Upon  closing  of  the  transaction, and for a  period  of  18  months
thereafter,  we  are  offering  you  a  position  as  Senior  Advisor,
Laboratory  Systems.  In this capacity, we expect  you  to  spend,  on
average 2-3 days per month as you serve in a consultative capacity  to
Cerner's laboratory leadership team.

In this capacity, you will be considered an active part-time associate
entitled  to all company benefits per our plans and receive a  monthly
gross  salary  of  $10,000.   As this position  may  require  personal
attendance at meetings or conferences in Kansas City or client  sites,
we  will  also reimburse appropriate travel and business expenses.  At
the  conclusion of this advisory assignment you will also be  eligible
to continue your health insurance through COBRA coverage for 18 months
or until September 30, 2003 at your option and expense.

Since  you  will  not  be technically retiring immediately  after  the
transaction closes, we agree that your Citation options will  continue
to  vest after they are converted to Cerner options under the terms of
the  original  stock option agreement and specified vesting  schedule.
Upon  leaving  Cerner, the retirement provision of your stock  options
will  be triggered as set forth in your original CITATION stock option
agreements.

Your  position  at  Cerner  is a professional,  exempt  position  that
requires  a  significant  level  of  responsibility,  discretion,  and
independent   judgment.  As  a  result,  it  carries   no   additional
compensation  for  overtime  worked.

Under  the  Immigration Reform and Control Act of 1986 and regulations

your identity and indicates that you are authorized for employment. If
you  are  unable to present the required document(s) within 3 business
days of the date employment begins, you must (1) present a receipt for
the  application for the document(s) within 3 business days;  and  (2)
indicate on the I-9 form that you are eligible to be employed  in  the
U.S.  Failure  to  comply  with  these  regulations  will  result   in
termination  of  your employment. We will be happy to explain  further
the documentation requirements for compliance with these regulations.

EMPLOYMENT AGREEMENT
- --------------------

Cerner  has  established significant momentum in  the  development  of
client   relationships,   professional  staff,   systems   development
methodology, and proprietary software products. We regard these  areas
as the most important assets owned by our Company. It is our intent to
guard  these assets closely. Therefore, every associate of the Company
is  required  to  execute  an  Employment  Agreement.  This  Agreement
includes  the  terms of your employment relationship  with  Cerner,  a
covenant not to disclose confidential client and internal information,
a  covenant not to compete against our Company in certain markets, and
establishes that, during the term of your employment, the benefits  of
your endeavors accrue to the Company. An Employment Agreement that has
been  updated  to  reflect your specific terms is  enclosed  for  your
review.

WORK ENVIRONMENT
- ----------------

For  the  benefit of all Cerner associates, all facilities are  `smoke

immediate vicinity.
