                                  THE COMPANY
 
    CITATION  Computer  Systems,  Inc. ("CITATION"  or  the  "Company") designs,
develops,  markets  and   supports  patient-centered   clinical  and   financial
information  systems  for  hospitals,  clinics,  physician  groups  and emerging
Integrated Delivery Networks ("IDNs"). The Company offers a comprehensive  suite
of  products using open client/server architecture to  meet a broad range of the
information systems needs  of the  healthcare industry.  The Company's  products
integrate  clinical,  financial  and  decision  support  information  within the
enterprise and provide  community-wide patient  registration and  identification
throughout   the  IDN.   The  Company's   systems  are   modular,  scalable  and
interoperable, enabling hospitals and  IDNs to purchase  systems that fit  their
specific needs and leverage their existing information technology.
 
    Since  the Company's  inception, CITATION  has developed client/server-based
solutions  for  clients   in  the   healthcare  industry.   CITATION  offers   a
comprehensive  suite  of  products  to  manage  information  in  the  healthcare
enterprise. CITATION offers products addressing four functional areas: clinical,
financial,  community  registration  and  decision  support.  As  part  of   its
continuing  efforts to deliver advanced solutions to its clients, the Company is
presently migrating substantially all of its products to a Windows NT  operating
system, which is an emerging client/server industry standard. In addition to its
own  development  efforts,  the  Company acquires  or  licenses  technologies or
products developed  by  third parties  that  complement and  enhance  CITATION's
internally developed product offerings.
 
    As  the need  for readily  accessible information  throughout the healthcare
enterprise continues to grow, hospitals, providers  and payors of all sizes  are
faced with the challenge of implementing healthcare information systems that are
scalable,  capable of working with existing information systems and adaptable to
changes in the  healthcare marketplace.  In the future,  as healthcare  delivery
systems become more complex and IDNs emerge, the Company believes that access to
information  and the  ability to integrate  patient data  from disparate sources
will grow  in importance.  For example,  a master  patient index  ties  together
information  about  individuals  no matter  where  or  how the  data  is stored,
providing a universal electronic record of a patient's demographic, clinical and
payor history.  In a  1996  survey conducted  by  Modern Healthcare/  Coopers  &
Lybrand  that appears in  the March 4,  1996 issue of  MODERN HEALTHCARE, 59% of
hospital chief information officers  surveyed identified master patient  indices
as one of their top four information priorities. In late calendar year 1996, the
Company  intends  to ship  its  master patient  index  product, the  Common User
Registration Entry  System,  CURES.  CURES distributes  demographic  and  health
assessment  information  across  multiple  sites  located  throughout healthcare
enterprises, IDNs or the  community. CURES is designed  to function as a  master
patient  index and as a central data  repository for all patient demographic and
health status  information,  streamlining  the  intake  process  by  eliminating
repetitive   registration  questions  about   medical  history  and  eligibility
information.
 
    CITATION's goal  is  to  leverage  its 15  years  of  experience  developing
client/server  application solutions to become  a leading provider of healthcare
information systems.  In order  to  achieve this  goal, the  Company's  strategy
includes  increasing the  number of  comprehensive systems  sales, expanding its
existing client  base  to include  larger  enterprises, broadening  its  product
portfolio  to address the changing needs  of healthcare enterprises and building
upon its international presence. CITATION's systems are installed in nearly  600
healthcare  institutions worldwide, ranging in size  from under 100 beds to over
1,000. CITATION markets its products directly in the United States, Canada,  the
United Kingdom and Europe as well as through distribution partners in the Middle
East, the Far East and Latin America.
 
    As  part  of  its strategy  to  sell  more comprehensive  systems  to larger
entities, the  Company intends  to expand  its sales  and marketing  effort.  In
addition,  the  Company sees  an opportunity  to  expand its  value-added client
support services by assisting clients in  the design and configuration of  their
systems,   including  networking,  systems   integration  and  data  conversion.
Furthermore, the Company intends  to provide advice on  data analysis to  assist
care providers in evaluating their operations.
 
    In Janury 1995, J. Robert Copper became Chairman and Chief Executive Officer
of  CITATION. From  that time  until September  1995, the  Company recruited and
reorganized its  senior  management to  improve  its operating  performance  and
position the Company for future growth. Under the guidance of the new management
team, in January 1995 the Company initiated a plan to restructure its operations
in  order to reduce  its cost structure.  In addition, in  June 1995 the Company
decided to consolidate the  operations of its  Madison, Wisconsin facility  into
its St. Louis, Missouri headquarters.

- ----------
 
(1) On December 11, 1992, the Company issued 596,559 shares of its Common  Stock
    in  exchange for all of the outstanding shares of Health Micro Data Systems,
    Inc. ("HMDS"). The merger was accounted  for as a pooling of interests,  and
    accordingly,  the  consolidated  financial  statements  of  the  Company for
    periods up to the date of consummation  of the merger have been restated  to
    include the accounts of HMDS.
 
(2)  In January 1995, the Company initiated a plan to restructure its operations
    in order to reduce its cost structure.  As a result, the Company incurred  a
    restructuring  charge of $3.4 million in  the fourth quarter of fiscal 1995.
    See Note 4 of Notes to Consolidated Financial Statements.
 
(3) In  June 1995,  the Company  decided to  consolidate the  operations of  its
    Madison,  Wisconsin facility into  its St. Louis,  Missouri headquarters and
    recorded a charge of $1.4 million for the related costs in the first,  third
    and  fourth quarters  of fiscal 1996.  The consolidation  and relocation has
    been substantially completed. See Note 3 of Notes to Consolidated  Financial
    Statements.
 
(4)  Adjusted to reflect the sale of 2,025,000 shares of Common Stock offered by
    the Company hereby at an assumed public offering price of $16.125 per  share
    and  the application  of the estimated  net proceeds therefrom.  See "Use of
    Proceeds."

                                  RISK FACTORS
 
    IN  ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, THE FOLLOWING RISK
FACTORS SHOULD  BE  CONSIDERED  CAREFULLY  IN EVALUATING  THE  COMPANY  AND  ITS
BUSINESS BEFORE PURCHASING THE SHARES OF COMMON STOCK OFFERED HEREBY.
 
    QUARTERLY  FLUCTUATIONS  IN  OPERATING  RESULTS.    The  Company's quarterly
results of operations have varied greatly in  the past and are expected to  vary
in  the  future  because of  the  relatively  high average  sales  price  of the
Company's information systems and long length of the sales process. In addition,
the Company is increasingly committed to international sales. Historically,  the
Company's  international  sales  have  been  more  volatile  than  the Company's
domestic sales on a quarterly basis. Any shortfall in revenues recognized in any
given period could  have a material  adverse effect on  the Company's  business,
results  of  operations  and  financial condition  for  such  period.  Because a
significant percentage  of the  Company's total  expenses is  relatively  fixed,
variations   in  the  timing  of  systems  sales  and  installations  can  cause
significant variations  in operating  results from  quarter to  quarter and  may
magnify the adverse effect of any shortfalls in revenue on the Company's results
of  operations.  The  Company  believes  that  period-to-period  comparisons  of
revenues and results of operations are not necessarily meaningful and should not
be relied upon as indicators of future performance. At some point in the  future
the  Company's quarterly results will likely  be below those projected by market
analysts. Quarterly results fluctuations  and variations from projections  could
have  a  significant  impact  on  the market  price  of  the  Common  Stock. See
"Management's Discussion  and Analysis  of Financial  Condition and  Results  of
Operations -- Quarterly Results of Operations."
 
    TECHNOLOGICAL CHANGE; DEPENDENCE ON NEW PRODUCT DEVELOPMENT.  The healthcare
information systems industry is characterized by rapid technological change. The
Company's  future success  will depend upon  its ability  to continually develop
software applications  that  incorporate new  technologies  and to  enhance  and
expand  its  current products.  There  can be  no  assurance that  the Company's
financial and technological resources  will permit it to  develop or market  new
products  successfully  or  respond effectively  to  technological  changes. The
Company anticipates that significant amounts  of future revenue will be  derived
from  products and product enhancements which either  do not exist today or have
not been  sold in  large  enough quantities  to  ensure market  acceptance.  The
development  of  new  systems  is a  complex,  expensive  and  uncertain process
requiring technical innovation  and the accurate  anticipation of  technological
and  market trends.  The Company  will need  to continue  to attract  and retain
appropriately skilled employees to successfully  develop new systems. There  can
be  no assurance  that the Company  will not experience  difficulties that could
delay  or  prevent  the  successful  development  and  introduction  of  product
enhancements  or new  products, or that  such enhancements or  new products will
adequately  meet  the  requirements  of   the  marketplace  or  achieve   market
acceptance.   If  the  Company  is  unable  to  develop  and  introduce  product
enhancements and new products in a timely and cost-effective manner in  response
to  changing market conditions  or client requirements,  the Company's business,
results of operations and financial condition could be materially and  adversely
affected.
 
    The  software products offered by the  Company may contain undetected errors
or failures when  first introduced or  as new versions  are released. Errors  or
failures  that  are  not detected  until  after the  commencement  of commercial
shipments of a product could result in loss of or delay in market acceptance  of
the  product and  in claims  against the  Company, which  could have  a material
adverse impact on the  Company's business, results  of operations and  financial
condition.
 
    PRODUCT  CONVERSIONS  TO  WINDOWS  NT.    The  Company  intends  to  migrate
substantially all  of its  products  to Windows  NT.  The Company  expects  that
Windows  NT will become  the operating system  foundation for a  large number of
healthcare enterprises, although there can be no assurance that this will be the
case. As  a  result  of the  complexities  involved  in the  conversion  of  the
Company's  products to  Windows NT,  the new  versions will  require significant
development and testing periods before they achieve marketability. There can  be
no  assurance that the Windows  NT versions will be  completed before demand for
the Company's software written  for other operating systems  slows. Some of  the
Company's  competitors  have  already been  able  to convert  their  products to
operate on Windows NT. Further,  certain potential clients may delay  purchasing
decisions  until Windows  NT versions of  the Company's  products are available.
There can be no assurance that the Company will not experience difficulties that
could delay or prevent the  successful and timely development, introduction  and
marketing   of  the   new  Windows  NT   versions  of  its   products,  or  that
 
                                       6
<PAGE>
such versions  will adequately  meet  the requirements  of the  marketplace  and
achieve  market acceptance. In addition,  the conversions could divert resources
away from developing or enhancing other products. The occurrence of any of these
potential product conversion problems  could have a  material adverse impact  on
the  Company's  business, results  of  operations and  financial  condition. See
"Business -- Products" and "Business -- Product Development."
 
    CHANGE IN MARKETING  FOCUS.  While  the Company has  traditionally sold  its
products  to small and  medium-sized hospitals, the Company  believes it will be
necessary to extend its  marketing efforts to  larger healthcare providers  with
which  the  Company has  less sales  experience.  Many healthcare  providers are
consolidating  to  create   larger  healthcare   delivery  organizations.   This
consolidation  reduces  the  number  of potential  customers  for  the Company's
products, and the increased purchasing  power of these organizations could  lead
to  reductions  in the  amounts  paid for  the  Company's products.  The Company
anticipates that the  laboratory information systems  market and the  integrated
healthcare information systems market will continue to expand despite a decrease
in the number of small and medium-sized hospitals, but there can be no assurance
that  such expansion will occur  in these markets. The  Company intends to focus
its sales efforts on selling more comprehensive products to large hospitals  and
IDNs.  Because the Company has expanded  its product offerings into an extensive
package of integrated products, purchases of the Company's products increasingly
require approval by a customer's  executive officers as opposed to  departmental
managers,  lengthening the sales process and rendering the sale more competitive
and uncertain. There can be no assurance that the Company will be successful  in
these  sales efforts. Failure  to compete successfully  in these market segments
could have  a material  adverse impact  on the  Company's business,  results  of
operations  and  financial condition.  See "Business  -- Business  Strategy" and
"Business -- Sales and Marketing."
 
    RISKS ASSOCIATED WITH FOREIGN  SALES.  In  1996 the Company's  international
sales  increased  to 12.2%  of total  revenues  from 6.0%  in 1995.  The Company
expects international sales to continue  to constitute a significant portion  of
its  revenues. The Company's sales outside the  United States are subject to the
risks that: agreements may be more difficult to enforce and that receivables may
be more difficult to collect through  a foreign country's legal system;  foreign
customers  often  have  longer  payment  cycles;  foreign  countries  could make
unexpected changes in regulatory requirements  or be the subject of  significant
political and economic instability; foreign subsidiaries, distributors and sales
representatives  may  be difficult  to  manage; foreign  countries  could impose
additional withholding  taxes or  otherwise tax  the Company's  foreign  income,
impose  tariffs or adopt  other restrictions on  foreign trade; and intellectual
property rights  may be  more  difficult to  enforce  in foreign  countries.  In
addition,  exchange  rate fluctuations  may render  the Company's  products less
competitive relative  to local  product offerings,  or could  result in  foreign
exchange  losses, depending  upon the  currency in  which the  Company sells its
products. To  date,  the  Company  has not  engaged  in  exchange  rate  hedging
activities  to minimize the risks of such  fluctuations. The Company may seek to
implement hedging techniques in the future with respect to its foreign  currency
transactions.  There  can be  no assurance,  however, that  the Company  will be
successful in  such  hedging activities.  Problems  arising from  the  Company's
international  sales  could  have a  material  adverse impact  on  the Company's
business, results of operations and financial condition. See "Business --  Sales
and Marketing."
 
    RISKS  ASSOCIATED WITH IDENTIFYING AND  INTEGRATING ACQUISITIONS.  A portion
of the net proceeds of  this offering and other  funds available to the  Company
may be used to acquire complementary products, technologies or businesses in the
healthcare   information  systems  industry.  The  evaluation,  negotiation  and
integration of any such acquisition may divert the time, attention and resources
of the Company, particularly its  management. In addition, there is  significant
competition  for acquisition opportunities in the healthcare information systems
industry. Consolidation  in  the industry  may  intensify such  competition  and
thereby increase the costs of such opportunities. There can be no assurance that
the Company will be able to identify suitable acquisition candidates, consummate
acquisitions  on terms favorable  to the Company,  or integrate successfully any
acquired products, technologies or businesses  into its current operations.  The
failure to do so could have a material adverse impact on the Company's business,
results  of operations and financial condition. See "Use of Proceeds," "Business
- -- Business Strategy" and "Business -- Product Development."
 
    COMPETITION.  The market for  healthcare information systems, including  the
market for the Company's information systems, is highly competitive. Most of the
Company's  revenues are derived from  lengthy, competitive procurement processes
managed  by   sophisticated   purchasers  that   extensively   investigate   and
 
                                       7
<PAGE>
compare  the  healthcare  information systems  offered  by the  Company  and its
competitors.  The  Company  believes  that  the  principal  competitive  factors
influencing the market for its healthcare information systems include vendor and
product  reputation, product  architecture, functionality and  features, ease of
use, rapidity of implementation, quality of client support, product  performance
and  price. There can be  no assurance that the Company  will be able to compete
successfully with respect to any of such factors. In the healthcare  information
systems  market, the  Company competes with  a large number  of other healthcare
information systems  vendors.  Many  of  the  Company's  current  and  potential
competitors  have  significantly  greater  financial,  managerial,  development,
technical, marketing and  sales resources than  the Company and  may be able  to
devote  those resources to develop and  introduce products more rapidly than the
Company or systems with significantly  greater functionality than, and  superior
overall performance to, those offered by the Company. These competitors may also
be  able to initiate and withstand  significant price decreases more effectively
than the Company. Moreover, the continuing consolidation of hospitals and  other
healthcare  providers has resulted  in fewer individual  purchasing decisions, a
trend that may favor larger vendors. To be competitive, the Company must be able
to respond  effectively  to the  introduction  of new  and  improved  healthcare
information  systems  by its  competitors. There  can be  no assurance  that the
Company will be able to develop new or improved healthcare industry  information
services in a timely and cost effective manner or that the Company's current and
future  healthcare information  systems and  services will  achieve and maintain
market acceptance. Failure of  the Company to effectively  compete could have  a
material  adverse impact  on the Company's  business, results  of operations and
financial condition. See "Business -- Competition."
 
    GOVERNMENT REGULATION.  The Company  is subject to the general  requirements
of  the Food and  Drug Administration's regulations for  Class I Medical Devices
because it  produces  C-CIS,  the Company's  clinical  information  system.  The
Company  has  decided  not  to internally  develop  products  (E.G.,  blood bank
software), at  this time,  that  would subject  the  Company to  the  pre-market
approval  requirements of  Section 510(k)  of the  Food, Drug  and Cosmetic Act.
Additional legislation governing the dissemination of medical record information
has been  proposed.  Currently  pending  in  Congress  is  the  Medical  Records
Confidentiality  Act  (the  "Medical  Records  Act"),  which  would  protect and
regulate the confidentiality of medical record information. The Medical  Records
Act  would  preempt  most  state  laws regarding  access  to,  and  the  use and
disclosure of,  medical  record  information.  If the  Medical  Records  Act  is
enacted,  compliance with  it could  be costly and  could preclude  or delay the
introduction of certain new products. The Company is unable to determine at this
time the effect, if any, that these requirements may have on its business. There
can be no assurance that future regulation of the healthcare industry would  not
have  a material adverse impact on the Company's business, results of operations
and financial condition. See "Business -- Regulation."
 
    HEALTHCARE INDUSTRY REFORM.  The healthcare industry is subject to  changing
political,  economic and regulatory  influences that may  affect the procurement
practices and operations of healthcare providers. Many lawmakers have  announced
that  they intend  to propose  programs to  reform the  United States healthcare
system. The Company cannot predict with any certainty what impact, if any,  such
legislative  or market-driven, regulatory reforms might have on its business and
results of operations. There can be no assurance that such proposed changes,  if
adopted,  would not  have a material  adverse impact on  the Company's business,
results of operations and financial condition. See "Business -- Regulation."
 
    PRODUCT LIABILITY.   The  Company's systems  include applications  that  may
relate  to  confidential  patient medical  histories,  clinical  information and
treatment plans. Improper disclosure of this  information or any failure by  the
Company's  systems to  provide accurate and  timely information  could result in
claims against the Company by its clients or their patients. A successful  claim
brought  against the Company  in excess of  its insurance coverage  could have a
material adverse effect  on the  Company's business, results  of operations  and
financial   condition,  and  even  unsuccessful   claims  could  result  in  the
expenditure of substantial funds in  litigation and the diversion of  management
time  and resources.  There can  be no  assurance that  the Company  will not be
subject to  such claims  in the  future, that  such claims  will not  result  in
liability  in excess  of any insurance  coverage maintained by  the Company with
respect  to  such  claims,  that  insurance  will  cover  such  claims  or  that
appropriate   insurance  will  continue  to  be  available  to  the  Company  at
commercially reasonable rates.
 
    INTELLECTUAL PROPERTY.  The  Company's success depends  upon its ability  to
prevent  the  unauthorized  use  of  its software  products,  none  of  which is
patented.   The    Company    relies   largely    on    copyright    protection,
 
                                       8
<PAGE>
license   agreements,  confidentiality  procedures  and  employee  nondisclosure
agreements to protect its proprietary rights. It may nonetheless be possible for
third  parties  to  misappropriate  the  Company's  technology  and  proprietary
information  or to develop  independently similar or  superior technology. There
can be no assurance that the legal  protections afforded to the Company and  the
measures  taken  by the  Company will  be adequate  to protect  its intellectual
property. In addition, the laws of  some foreign countries in which the  Company
sells, or may in the future sell, its products do not protect proprietary rights
to as great an extent as do the laws of the United States. Moreover, the Company
is  subject to  the risk  that others  will assert  adverse claims  and commence
litigation alleging  infringement  or  misappropriation  of  their  intellectual
property  rights.  Any  such claims  regardless  of  their merit  could  be time
consuming, result in costly  litigation, delay or  prevent product shipments  or
require  the Company to enter into costly royalty or licensing agreements. There
can be  no assurance  that the  Company  would be  able to  develop  alternative
technology  or  that  any necessary  licenses  would  be available  or  that, if
available, such licenses could be obtained on commercially reasonable terms. The
occurrence of any of the foregoing could  have a material adverse impact on  the
Company's business, results of operations and financial condition. See "Business
- -- Intellectual Property."
 
    DEPENDENCE ON KEY PERSONNEL.  The success of the Company is dependent on the
efforts  and abilities  of its  senior executive  officers. In  January 1995, J.
Robert Copper became Chairman and Chief Executive Officer of CITATION. From that
time until  September 1995,  the Company  recruited and  reorganized its  senior
management.  There  can  be no  assurance  that  this new  management  team will
continue to be successful. Loss  of one or more  members of the management  team
could  have  a material  adverse impact  on the  Company's business,  results of
operations and financial condition. See "Management."
 
    POSSIBLE VOLATILITY OF STOCK  PRICE.  The market  price of the Common  Stock
could  be subject to significant  fluctuations in response to quarter-to-quarter
variations in the  Company's operating results,  announcements of  technological
innovations  or new  products by  the Company  or its  competitors, governmental
regulatory actions,  general  trends  in  the  industry  and  other  events.  In
addition,  the stock  market in  recent years  has experienced  price and volume
fluctuations  that  have  particularly  affected  the  market  prices  of   many
technology  companies and that have often  been unrelated or disproportionate to
the operational performance of these  companies. These fluctuations, as well  as
general  economic and market  conditions, could materially  and adversely affect
the market price of the Common Stock. See "Price Range of Common Stock."
 
    SHARES ELIGIBLE  FOR FUTURE  SALE;  POTENTIAL FOR  ADVERSE EFFECT  ON  STOCK
PRICE.   Sales of substantial amounts of Common Stock in the public market could
have a material adverse  impact on the  market price of  the Common Stock.  Upon
completion  of this offering,  substantially all shares  of the Company's Common
Stock will be freely tradeable without  restriction, or may be sold pursuant  to
Rule  144 under the Securities  Act of 1933, as  amended (the "Securities Act").
The Company, its  Directors, executive  officers and  the Selling  Shareholders,
beneficially holding an aggregate of 2,125,528 shares of Common Stock (excluding
shares  offered  hereby  other  than the  shares  subject  to  the Underwriters'
over-allotment option), have  agreed that they  will not sell  any Common  Stock
without  the prior consent  of Volpe, Welty &  Company for a  period of 120 days
from the date of this Prospectus  (the "Lockup Period"). Upon expiration of  the
Lockup  Period, these shares will become eligible for immediate sale, subject in
certain cases to volume and other  limitations under Rule 144. Additionally,  at
June  30,  1996,  options  to  purchase  291,497  shares  of  Common  Stock were
outstanding, of which options to  purchase 283,497 shares were exercisable.  The
Company  has filed  a registration  statement to  permit the  shares acquired on
exercise of options  to be  freely tradeable.  See "Shares  Eligible for  Future
Sale" and "Underwriting."
 
    ANTI-TAKEOVER  PROVISIONS.  Certain provisions  of the Company's Articles of
Incorporation and By-laws may be regarded as "anti-takeover" provisions  because
they  could have the effect of limiting the ability of other entities or persons
to acquire  control of  the Company.  The existence  of these  provisions  could
materially  and  adversely affect  the  market price  of  the Common  Stock. See
"Description of  Capital Stock  --  Anti-Takeover Effects  of Missouri  Law  and
Articles of Incorporation and By-laws."

                                  THE COMPANY
 
    The  Company was organized in 1979  as a Missouri corporation. The Company's
principal executive  office is  located  at 424  South  Mills Road,  Suite  200,
Chesterfield,  Missouri 63017  and its telephone  number is  (314) 579-7900. The
Company also has a branch office in London.
 
                                USE OF PROCEEDS
 
    The net  proceeds to  the Company  from  the sale  of the  2,025,000  shares
offered  by the Company hereby (after deducting estimated underwriting discounts
and commissions and estimated offering  expenses), at an assumed offering  price
of  $16.125 per  share, are estimated  to be approximately  $30.3 million ($33.5
million if the Underwriters'  over-allotment option is  exercised in full).  The
Company  will not  receive any of  the proceeds from  the sale of  shares by the
Selling Shareholders. See "Principal and Selling Shareholders."
 
    The Company intends to  use the net proceeds  from the offering for  working
capital and general corporate purposes, including sales force expansion, product
development  and acquisitions  of complementary businesses  and technologies. No
material acquisitions are currently pending.  The net proceeds will be  invested
by  the  Company in  short-term,  interest-bearing, investment  grade securities
until used for such purposes.
 
                                DIVIDEND POLICY
 
    The Company has never declared or  paid cash dividends on its Common  Stock.
Pursuant  to the Company's line of credit agreement, the Company may not declare
or pay any dividends without the prior written consent of the lender thereunder.
The Company anticipates that it will retain all of its net earnings or available
funds, if any, for use in the  operation and expansion of its business and  does
not  anticipate paying any cash dividends on its Common Stock in the foreseeable
future.

(1) On December 11, 1992, the Company issued 596,559 shares of its Common  Stock
    in  exchange  for all  of the  outstanding  shares of  HMDS. The  merger was
    accounted for as a pooling  of interests, and accordingly, the  consolidated
    financial  statements  of  the  Company  for  periods  up  to  the  date  of
    consummation of the  merger have been  restated to include  the accounts  of
    HMDS.
 
(2)  In January 1995, the Company initiated a plan to restructure its operations
    in order to reduce its cost structure.  As a result, the Company incurred  a
    restructuring  charge of $3.4 million in  the fourth quarter of fiscal 1995.
    See Note 4 of Notes to Consolidated Financial Statements.
 
(3) In  June 1995,  the Company  decided to  consolidate the  operations of  its
    Madison,  Wisconsin facility into  its St. Louis,  Missouri headquarters and
    recorded a charge of $1.4 million for the related costs in the first,  third
    and  fourth quarters  of fiscal 1996.  The consolidation  and relocation has
    been substantially completed. See Note 3 of Notes to Consolidated  Financial
    Statements.

OVERVIEW
 
    CITATION designs, develops, markets  and supports patient-centered  clinical
and  financial information systems for  hospitals, clinics, physician groups and
emerging  Integrated   Delivery  Networks   ("IDNs").  The   Company  offers   a
comprehensive  suite of products using open client/server architecture to meet a
broad range of the information systems  needs of the healthcare industry.  These
products  integrate  patient care  processes within  the enterprise  and provide
community-wide patient registration and  identification throughout the IDN.  The
Company's  systems are  modular, scalable, and  allow clients  to leverage their
investments in existing systems. Individual components of the Company's  systems
can  function independently,  giving clients the  ability to  build their system
over time and  to integrate  existing software  which is  meeting their  current
needs.  CITATION's systems are  installed in nearly  600 institutions ranging in
size from fewer  than 100 beds  to more  than 1,000 beds.  CITATION markets  its
products  directly in the United States,  Canada, the United Kingdom, and Europe
as well as through distribution partners in  the Middle East, the Far East,  and
Latin America.
 
    The  Company generates  revenues from  the sale  of information  systems and
services.  System  sales  consist   of  software  licenses,  related   hardware,
installation  and  training,  and  the sale  of  third-party  software. Hardware
revenues are generated from sales of third-party manufactured hardware typically
sold in  conjunction  with  the Company's  software.  Service  revenue  includes
maintenance and support services.
 
    The  sales cycle for the  Company's systems is typically  six to nine months
from initial contact to  contract execution. Depending  upon the combination  of
products   purchased  and  the  installation  schedule,  installation  typically
requires six  to  12 months.  Revenue  from  systems sales  is  recognized  upon
shipment  to the client  provided that no  significant vendor obligations remain
and collection of the related receivable is deemed probable. Revenue related  to
the  installation is  recognized as  the work  is performed.  Service revenue is
recognized ratably over the term of the contract period. Revenue recognized from
the sale of hardware as a percentage of total revenue has declined from 18.7% in
fiscal 1995 to 14.6% in fiscal 1996 because of increased software sales and also
because the Company's clients are buying hardware directly from third parties.
 
    Cost of products and services sold includes cost of system sales and cost of
service  revenue.  Cost  of  system  sales  includes  cost  of  hardware   sold,
installation  and training expenses, and software amortization expenses. Cost of
service revenue  includes all  client  service expenses  plus an  allocation  of
certain other overhead expenses.
 
    Research  and development expenses include  salaries and expenses related to
development and  documentation  of  software  systems,  reduced  by  capitalized
software  development costs. Software development  costs are expensed until such
time as technological  feasibility is  established and then  are capitalized  in
compliance  with Statement of Financial  Accounting Standards No. 86 "Accounting
for the Costs of Computer Software to be Sold, Leased or Otherwise Marketed."
 
    Sales and  marketing expenses  include salaries,  commissions,  advertising,
trade  show costs, and user group costs related to the sale and marketing of the
Company's systems.  General and  administrative  expenses include  salaries  and
expenses  for the corporate administration, finance, legal, and human resources,
as well as profit sharing, bonuses and insurance.

    In January  1995,  J. Robert  Copper  became Chairman  and  Chief  Executive
Officer  of  the  Company. From  that  time  until September  1995,  the Company
recruited and  reorganized  its  senior  management  to  improve  its  operating
performance and position the Company for future growth.
 
    In  January 1995, the Company initiated a plan to restructure its operations
in order to  reduce its  cost structure.  As a  result, the  Company incurred  a
restructuring  charge of $3.4 million in the  fourth quarter of fiscal 1995. See
Note 4  of  Notes  to  Consolidated Financial  Statements  for  details  of  the
restructuring charge.
 
    In  June 1995, the new management team decided to consolidate the operations
of its Madison, Wisconsin  facility into its  St. Louis, Missouri  headquarters.
During  the fiscal year ended  March 31, 1996, the  Company recorded a charge of
$1.4 million for the  related costs. The consolidation  and relocation has  been
substantially  completed.  See Note  3 of  the  Notes to  Consolidated Financial
Statements for details of the office consolidation and relocation charge.

</TABLE>
 
  COMPARISON OF FISCAL YEAR ENDED MARCH 31, 1995 TO FISCAL YEAR ENDED MARCH 31,
1996
 
    REVENUE.  Total revenues increased 7.2% from $23.4 million in fiscal 1995 to
$25.1 million in fiscal 1996 due to a 5.7% increase in system sales, and a 10.1%
increase in  service revenue.  Revenues from  domestic operations  were flat  in
fiscal  1996. However, revenues increased at  accelerated rates during the third
and fourth quarters of  fiscal 1996. The Company  believes that the results  for
the  first six months of  the year were negatively  impacted by (i) a management
reorganization within  the Company,  (ii) the  refocusing of  its sales  efforts
toward larger, fully integrated hospital information systems sales and (iii) the
consolidation of its
 
                                       14
<PAGE>
domestic operations. The increased revenues in the third and fourth quarters are
due  to this  refocusing of  sales efforts  in the  United States  and increased
efforts to sell the  products internationally. International revenues  increased
119%  to $3.1 million in fiscal 1996. This increase is due to several key system
sales to  hospitals  in  England,  Ireland and  the  Netherlands.  Domestic  and
international sales represented 87.8% and 12.2% of total revenues, respectively,
in fiscal 1996.
 
    System sales increased from $15.3 million in fiscal 1995 to $16.2 million in
fiscal  1996. The  5.7% increase in  system sales was  primarily attributable to
additional revenue generated  from international operations.  While the  Company
sold fewer systems in fiscal 1996 as compared to fiscal 1995, the average system
contract  value was  higher in fiscal  1996. The higher  average system contract
value reflects the growth in the sale of more comprehensive systems. The average
system contract value increased  from approximately $180,000  in fiscal 1995  to
approximately  $280,000 in 1996. This trend was especially evident in the fourth
quarter of fiscal year 1996 during which the average systems contract  increased
166%  from $154,000 during the  fourth quarter of fiscal  year 1995 to $410,000.
System sales represented 65.6% and 64.7% of total revenues in fiscal years  1995
and 1996, respectively.
 
    Service  revenue increased from $8.0 million  in fiscal 1995 to $8.8 million
in fiscal  1996. The  10.1% increase  was primarily  due to  additional  service
revenue from the growth in the client base and renewals of maintenance contracts
from  existing clients.  Service revenue  represented 34.4%  and 35.3%  of total
revenues in fiscal years 1995 and 1996, respectively.
 
    COST OF PRODUCTS AND SERVICES SOLD AND  GROSS PROFIT.  Cost of products  and
services  sold includes cost  of hardware sold,  installation and client service
expenses, and software  amortization costs.  Cost of sales  relating to  service
revenue includes all client service expenses plus an allocation of certain other
expenses  based upon  estimates made by  management. Total cost  of products and
services sold decreased from $11.9 million in 1995 to $11.1 million in 1996. The
total cost of products and services sold decreased from 50.8% of total  revenues
in  fiscal 1995 to 44.2%  in fiscal 1996. The decrease  was primarily due to the
decrease in hardware costs as a percentage  of total revenues and a decrease  in
client  service  expense  reflecting  the closing  of  the  Madison  office. The
decreases in hardware costs and client service expenses were offset by a  slight
increase  in amortization of  capitalized software costs  for the year. Software
amortization costs of  $1.7 million in  fiscal 1995 and  $1.8 million in  fiscal
1996  represented 14.4% and 16.2%, respectively,  of total costs of products and
services sold for fiscal years 1995 and 1996.
 
    Gross profit increased  $2.5 million from  $11.5 million in  fiscal 1995  to
$14.0  million in fiscal  1996. Gross profit  as a percentage  of total revenues
increased from 49.2% in fiscal  1995 to 55.8% in  fiscal 1996. The increase  was
primarily  attributable to higher average per  system contract value and a lower
hardware component as a percentage of the system contract value. Several  system
sales  in fiscal 1996 were software-only sales, which have a higher gross profit
percentage than  similarly  priced  systems  which  include  both  software  and
hardware.
 
    RESEARCH  AND DEVELOPMENT EXPENSES.   Total outlays for software development
for fiscal years 1995 and 1996 were $5.3 million and $4.4 million, respectively,
representing 22.8% and 17.6%  of total revenues for  those periods. The  Company
capitalized  $3.6  million  in fiscal  1995  and  $2.6 million  in  fiscal 1996,
resulting in research and  development expense of $1.7  million for both  fiscal
years  1996 and 1995. The decrease of $1.0 million in total outlays for software
development was primarily due to the consolidation of domestic development  into
one  location.  Software development  costs  for domestic  operations  were $3.5
million in fiscal year 1996 of which $2.0 million was capitalized.
 
    SELLING AND ADMINISTRATIVE EXPENSES.  Selling and administrative expenses as
a percentage of total revenues decreased  from 39.4%, or $9.2 million in  fiscal
1995,  to 34.8%,  or $8.7 million  in fiscal  1996. The decrease  in selling and
administrative  expenses  as  a  percentage  of  total  revenues  resulted  from
consolidating  domestic operations  in St. Louis.  The $0.5  million decrease is
also due  to  lower costs  associated  with the  support  of both  domestic  and
international operations.
 
                                       15
<PAGE>
    OFFICE  CONSOLIDATION AND RELOCATION.  A charge of $1.4 million was recorded
in fiscal  1996  to  provide  for costs  of  the  consolidation  of  facilities,
settlement  of related employee  claims and the  relocation of certain employees
and equipment due to the consolidation of domestic operations in St. Louis.
 
    OPERATING INCOME.    Operating income  for  fiscal 1996  increased  to  $3.6
million,  excluding $1.4 million in office consolidation and relocation charges,
from $0.6 million,  excluding restructuring  charges of $3.4  million in  fiscal
1995.  The increase in operating income is due to the growth in revenues and the
reduction in  the  cost  of  sales  and  selling  and  administrative  expenses.
Including  the above non-recurring charges, the  Company incurred a loss of $2.2
million in fiscal 1995 compared with operating income of $2.8 million in  fiscal
1996.
 
    INCOME TAXES.  The Company's effective income tax (benefit) rate was (32.5)%
in  fiscal 1995 versus 39.0%  in fiscal 1996. The  fiscal 1995 rate reflects the
non-deductibility for tax purposes  of a relatively minor  portion of the  asset
write-offs included in the restructuring costs recorded during the year.
 
  COMPARISON OF FISCAL YEAR ENDED MARCH 31, 1994 TO FISCAL YEAR ENDED MARCH 31,
1995
 
    REVENUE.  Total revenues increased 8.5% from $21.5 million in fiscal 1994 to
$23.4 million in fiscal 1995 due to a 3.9% increase in system sales and an 18.7%
increase in service revenue.
 
    System sales increased from $14.8 million in fiscal 1994 to $15.3 million in
fiscal  1995. The  3.9% increase in  system sales was  primarily attributable to
additional revenue generated  from international operations.  While the  Company
sold fewer systems in fiscal 1995 as compared to fiscal 1994, the average system
contract  value was  higher in fiscal  1995. The higher  average system contract
value reflects  the  growth  in  the sale  of  systems  consisting  of  clinical
information  systems. In fiscal 1994 less than  10% of system sales (as measured
by the  number of  contracts sold)  consisted of  clinical information  systems,
versus  20% in fiscal  1995. System sales  represented 68.6% and  65.6% of total
revenues in fiscal years 1994 and 1995, respectively. Revenue from international
sales represented 3.2% and 6.0% of total revenues in fiscal years 1994 and 1995,
respectively.
 
    Service revenue increased from $6.8 million  in fiscal 1994 to $8.0  million
in  fiscal  1995. The  18.7% increase  was primarily  due to  additional service
revenue from the  growth in the  client base and  renewals of service  contracts
from  existing clients.  Service revenue  represented 31.4%  and 34.4%  of total
revenues in fiscal years 1994 and 1995, respectively.
 
    COST OF PRODUCTS AND SERVICES  SOLD AND GROSS PROFIT.   For fiscal 1994  and
1995,  total cost  of products  and services sold  were $10.5  million and $11.9
million, respectively, for a  12.8% increase in fiscal  1995. The total cost  of
products and services sold increased from 48.9% of total revenues in fiscal 1994
to  50.8% in  fiscal 1995.  The increase  was primarily  due to  the increase in
amortization of capitalized software costs for the year, related to the increase
in product development expenditures over the past two years, and to an  increase
in  client service expenses related to additional employees hired to support the
growth in  the client  base.  The increases  in  amortization costs  and  client
service  expenses  were offset  by  a slight  decrease  in hardware  costs  as a
percentage of total  revenues. Software  amortization costs of  $1.3 million  in
fiscal  1994  and  $1.7 million  in  fiscal  1995 represented  12.1%  and 14.4%,
respectively, of total costs of products and services sold for fiscal years 1994
and 1995.
 
    Gross profit increased  $0.5 million from  $11.0 million in  fiscal 1994  to
$11.5  million in fiscal 1995.  While gross profit increased,  gross profit as a
percentage of total  revenues decreased from  51.1% in fiscal  1994 to 49.2%  in
fiscal  1995. The  decrease in  gross profit as  a percentage  of total revenues
primarily reflects the fact  that the increases  in software amortization  costs
(34.3%),  and client  service expenses  (15.2%) outpaced  the increase  in total
revenues (8.5%) in fiscal 1995.
 
    RESEARCH AND DEVELOPMENT COSTS.  Total outlays for software development  for
fiscal  years 1994  and 1995 were  $3.7 million and  $5.3 million, respectively,
representing 17.0% and 22.6%  of total revenues for  those periods. The  Company
capitalized  $2.4  million  in fiscal  1994  and  $3.6 million  in  fiscal 1995,
resulting in research and development expense  of $1.3 million and $1.7  million
for  fiscal years 1994 and  1995, respectively. The increase  of $1.7 million in
total  outlays   for   software  development   was   primarily  due   to   costs
 
                                       16

associated  with allocating more  resources to the  development of new products,
such as Windows-based products and  enhancements to existing products. See  also
the discussion of restructuring of operations following.
 
    SELLING AND ADMINISTRATIVE EXPENSES.  Selling and administrative expenses as
a  percentage of total revenues increased from  35.8%, or $7.7 million in fiscal
1994 to  39.4% or  $9.2 million  in fiscal  1995. The  increase in  selling  and
administrative  expenses as a percentage of total revenues resulted from selling
and administrative  expenses  increasing at  a  greater rate  (19.4%)  than  the
increases  in total revenues  (8.5%). Total selling  and administrative expenses
increased $1.5 million primarily due to costs associated with higher selling and
administrative costs  to  support  international  and  domestic  operations.  In
addition,  the increase is attributable to increases in facilities and equipment
expenses resulting from moving to new  offices, as well as increases to  ongoing
expenses  related to  insurance, taxes, professional  services, travel, salaries
and benefits.
 
    RESTRUCTURING OF OPERATIONS.  During the fourth quarter of fiscal 1995,  the
Company  incurred a restructuring  charge of $3.4 million.  In January 1995, the
Company initiated a plan  to restructure its operations  in order to reduce  its
cost  structure and remain  competitive. The restructuring  charge includes $2.8
million related  primarily  to  the write-off  of  capitalized  software  costs,
inventory  and intangible assets associated with discontinued product lines, and
$0.6 million for severance and related benefit costs associated with changes  in
the  Company's executive management. The restructuring required a cash outlay of
approximately $0.3  million  in  fiscal  1995 and  required  a  cash  outlay  of
approximately $0.3 million in fiscal 1996.
 
    OPERATING  INCOME.    Operating  income for  fiscal  1994  was  $2.0 million
compared to $0.6 million in fiscal 1995 (excluding restructuring charges of $3.4
million in 1995). The decrease in operating income before restructuring costs of
$1.4 million reflected growth in revenue at a slower rate than growth in various
expenses,  including  increased  product  development  expenditures  and  higher
selling  and  administrative costs  to  support the  international  and domestic
operations.
 
    INCOME TAXES.  The Company's effective  income tax (benefit) rate was  37.6%
in  fiscal 1994 versus (32.5)% in fiscal 1995. The fiscal 1995 rate reflects the
non-deductibility for tax purposes  of a relatively minor  portion of the  asset
write-offs described in restructuring of operations above.

</TABLE>
 
    The Company's  quarterly  revenues and  results  of operations  have  varied
significantly in the past, and are likely to vary in the future as a result of a
number  of  factors,  including: the  volume  and  timing of  systems  sales and
installations;  the  Company's  internal   management  changes  and   facilities
consolidation  efforts;  the  timing  of  client  acceptances;  the  length  and
complexity of the systems sales and installation cycles; seasonal buying  trends
as  a  result of  clients' annual  purchasing and  budgeting practices;  and the
increased size of  the average contract.  While the Company  expects that  these
variations will continue for the foreseeable future, it believes that the impact
of  the Company's internal changes will be less dramatic. However, the timing of
revenue recognition is difficult to forecast because the Company's systems sales
and installation cycles  are relatively  long and frequently  depend on  factors
such  as the  size and scope  of installations and  general economic conditions.
Also,  because  a  significant  percentage  of  the  Company's  total  expenses,
particularly employee compensation, is relatively fixed, variations in timing of
systems  sales and installations  can cause significant  variations in operating
results from quarter to quarter. If total revenues are below expectations in any
period, the Company's inability to adjust  spending to compensate fully for  the
lower  revenues  may magnify  the  adverse effect  of  such a  shortfall  on the
Company's results of  operations. Accordingly,  period-to-period comparisons  of
revenues and results of operations may not necessarily be meaningful and are not
necessarily indicative of future results.

LIQUIDITY AND CAPITAL RESOURCES
 
    The  Company's primary source of liquidity  is cash flow from operations. At
March 31, 1995, the  Company had cash  and cash equivalents  of $2.6 million  as
compared to $2.1 million at March 31, 1996.
 
    The Company generated cash from operations of $2.4 million, $2.4 million and
$2.7  million in fiscal years  of 1994, 1995 and  1996, respectively. Total cash
decreased $2.2 million in  fiscal 1995. The decrease  was primarily due to  $4.8
million  used in  investing activities,  including $3.6  million for capitalized
software offset  by cash  provided by  operations. Fiscal  1995 cash  flow  from
operating activities includes a non-cash restructuring charge of $2.6 million.
 
    For  the year ended  March 31, 1996,  the Company generated  $2.7 million in
cash from operating activities,  and used $3.0  million in investing  activities
(including  $2.6 million for  capitalized software development  and $0.4 million
for capital expenditures). Cash from investing activities was immaterial.
 
    As of March  31, 1996, the  Company had a  line of credit  agreement with  a
bank. The line of credit allows the Company to borrow up to $1.0 million through
July  1996 with interest at the bank's prime rate (8.25% at March 31, 1996). The
line of credit is  secured by the Company's  accounts receivable, inventory  and
general intangible assets. The Company anticipates that it will renew or replace
its line of credit with a similar facility. There were no borrowings outstanding
under the line of credit agreement as of March 31, 1996.
 
    The  Company's  current  commitments consist  primarily  of  operating lease
obligations aggregating  $3.9 million  over the  next ten  years. The  operating
leases  consist primarily of the Company's  office lease in St. Louis, Missouri,
which expires in May 2004.
 
    The Company believes that its cash  and cash equivalents, together with  its
current  borrowing facilities, cash generated  from operations and cash proceeds
from this offering will be sufficient to fund its anticipated cash  requirements
for  at  least  the next  12  months. The  Company's  ability to  meet  its cash
requirements on  a long-term  basis  will depend  on profitable  operations  and
consistent and timely collections of its accounts receivable.
 
INFLATION AND CHANGING PRICES
 
    The  Company  believes  inflation  has  not had  a  material  effect  on the
Company's operations or its financial condition.
 
NEW ACCOUNTING STANDARDS
 
    In October 1995, the Financial  Accounting Standards Board issued  Statement
of   Financial  Accounting   Standards  No.  123   "Accounting  for  Stock-Based
Compensation"  ("FAS  123"),  which  addresses  accounting  for  stock  options,
purchase  and award plans.  FAS 123 specifies that  companies utilize either the
"fair value based  method," or the  "intrinsic value based  method" for  valuing
stock  options granted. The  Company will adopt  FAS 123 during  the year ending
March 31, 1997, and  expects to utilize the  "intrinsic value based method"  for
valuing  stock options granted.  The Company anticipates  that when adopted, FAS
123 will  have no  material effect  on its  consolidated financial  position  or
consolidated results of operations.

INDUSTRY BACKGROUND
 
    The  United States healthcare industry is  undergoing rapid change. In 1995,
healthcare  expenses   in  the   United  States   approximated  $1.0   trillion.
Historically,  reimbursement  for  healthcare  services  has  been  based  on  a
fee-for-service model  of payment.  With increasing  pressure to  reduce  costs,
managed  care organizations and other payors  are shifting the economic risk for
the delivery  of care  to providers  through alternative  reimbursement  models,
including  capitation and fixed fees. As  a result, healthcare providers such as
hospitals, multi-specialty  physician  groups,  laboratories,  pharmacies,  home
health services and nursing homes are integrating horizontally and vertically to
create  IDNs. IDNs are designed to serve all of the healthcare needs of regional
populations while achieving economies of scale.
 
    In order to lower healthcare  delivery costs while maintaining or  improving
the  quality of  patient care,  providers need  access to  detailed clinical and
management information to  (i) manage  the patient care  process throughout  the
IDN;  (ii)  automate patient  care  documentation; (iii)  compare  care provider
performance and clinical and cost outcomes  both within the organization and  to
established  norms; (iv) monitor  performance under managed  care contracts; (v)
monitor practice patterns of care  providers; (vi) measure the effectiveness  of
new  technologies and therapeutics;  and (vii) support  intra and inter facility
communication. A comprehensive  healthcare information  system must  be able  to
assist  both  clinicians  and  administrators  in  managing  patient information
throughout the continuum of care.
 
    Certain information-intensive departments of healthcare organizations,  such
as  laboratories, were early adopters of  information systems in order to manage
workflow and  clinical data.  However, as  multiple legacy  systems have  become
increasingly  prominent on  an enterprise-wide  basis, the  integration of these
systems across  the enterprise  has become  more difficult  given the  different
architectures, platforms and operating systems of these information systems.
 
    Integration  and  accessibility  to  patient  information  are  increasingly
necessary for  healthcare  providers  to operate  efficiently  and  improve  the
quality  of  patient  care. For  example,  creation  of a  master  patient index
represents  a  current  information  goal  of  many  hospitals,  providers  and,
increasingly,  IDNs.  A master  patient  index ties  together  information about
individuals no matter  where or how  the data is  stored, integrating data  from
disparate  systems and  providing a universal  electronic record  of a patient's
demographic, clinical and payor  history. In a 1996  survey conducted by  Modern
Healthcare/Coopers  & Lybrand that appears in the  March 4, 1996 issue of MODERN
HEALTHCARE, 59%  of  hospital  chief information  officers  surveyed  identified
master  patient indices as one of their top four information priorities, and 54%
identified remote access to data  as another pressing information systems  need.
Further,  a majority of  executives surveyed indicated that  they either have or
are planning for operations that extend  beyond the hospital to integrate  other
elements  of the healthcare system such as physicians, outpatient facilities and
payors.
 
    As the need  for readily  accessible information  throughout the  healthcare
enterprise  continues to grow, hospitals, providers  and payors of all sizes are
faced   with   the    challenge   of    implementing   healthcare    information
 
                                       20
<PAGE>
systems  that are scalable, capable of working with existing information systems
and flexible  to adapt  to changes  in the  healthcare marketplace.  Also,  such
systems  must  be  patient-centered,  integrating all  aspects  of  managing the
healthcare  process,   such  as   clinical   care,  financial   management   and
administrative decision support.
 
THE CITATION SOLUTION
 
    CITATION  designs, develops, markets and  supports products that address the
healthcare industry's need for  patient-centered, fully integrated clinical  and
financial information systems. CITATION's products are designed using a modular,
client/server approach, offering clients the ability to build their systems over
time  and  to  allow  existing  legacy  applications  to  interoperate  with the
Company's products.
 
    CURES, the Common User Registration Entry System, which the Company  expects
to  ship to  clients in late  calendar 1996, distributes  demographic and health
assessment information  across  multiple disparate  entities  within  healthcare
enterprises  or  IDNs. CURES  serves  as a  central  data repository,  or master
patient index,  for  all  patient demographic  and  health  status  information,
streamlining the intake process by eliminating repetitive registration questions
about medical history and eligibility information.
 
BUSINESS STRATEGY
 
    CITATION's  goal is  to leverage its  experience of over  fifteen years with
client/server application solutions to become  a leading provider of  healthcare
information systems. The Company's strategy for achieving this goal includes the
following elements:
 
    TARGET  COMPREHENSIVE SYSTEM  SALES.   CITATION intends  to focus  its sales
efforts on selling larger,  more comprehensive systems  to larger hospitals  and
IDNs  to address a broad range of needs. The Company's new management team began
to implement this strategy in April 1995.  In the fourth quarter of fiscal  1996
the  average systems contract value  was $410,000, an increase  of 166% from the
fourth quarter of the previous year.
 
    LEVERAGE EXISTING  CLIENT  BASE.    With  an  installed  base  of  over  600
facilities,  the Company believes it has  the potential to cross-sell additional
products to  its  existing  clients  because many  of  those  clients  have  not
purchased  all of  the Company's  products. CITATION's  products are  modular in
design and can be added over time as each client's needs expand and evolve.
 
    EXPAND PRODUCT PORTFOLIO.  The Company  plans to expand its product line  to
meet  the evolving needs  of its clients. The  Company continually evaluates its
offerings to determine what additional products or enhancements are required  by
the  healthcare  information systems  marketplace and  the Company  develops and
enhances products internally to meet clients' needs. If the Company can purchase
or license proven products at reasonable  cost on its chosen technology base  it
will  do  so in  order  to avoid  the time  and  expense involved  in developing
products.
 
    CAPITALIZE ON INTERNATIONAL MARKETS.   CITATION believes that a  significant
opportunity exists to expand the sales of its products in international markets.
Healthcare  providers  in  a  number  of  countries  have  not  yet  invested in
sophisticated information systems, and increasingly they are seeking to purchase
state-of-the  art  products,  particularly  clinical  information  systems.  The
Company believes that its open, client/server architecture and modular, scalable
systems  provide  a  cost  effective solution  to  these  markets.  CITATION has
successfully entered  several international  markets  through a  combination  of
direct sales and distribution arrangements.
 
    EXPAND  SERVICES.   The  Company intends  to expand  the range  of strategic
client support  and  data  interpretation  services  it  provides  in  order  to
strengthen  relationships  with  clients.  The  Company  intends  to  expand its
services to  design  and  configure  the architecture  of  a  client's  systems,
including  networking,  systems integration  and  data conversion.  Further, the
Company intends to provide advice on  data analysis to assist care providers  in
evaluating their operations.
 
    EXTEND  BEYOND  HOSPITALS TO  THE IDN  MARKET.   Leveraging  the opportunity
presented by CURES  and the  Company's other existing  products as  well as  its
position in the hospital market, CITATION believes that it is well positioned to
broaden its product array to offer products which meet the complete needs of the
IDN.  These opportunities  include physician  practice management,  home health,
long-term care and specialty facilities, including psychiatric care,  ambulatory
care and rehabilitation.
 
                                       21

PRODUCTS
 
    CITATION   has  developed  a  comprehensive  suite  of  products  to  manage
information in the healthcare enterprise. A client can purchase a  comprehensive
system  or can buy modules separately  to match its individual needs. CITATION's
systems  address  the   information  needs  of   care  providers  and   hospital
administrators  by  enabling  joint  access to  clinical  and  cost information,
thereby facilitating cost containment, effective decision making and delivery of
high-quality care. CITATION  offers products addressing  four functional  areas:
clinical, financial, community registration and decision support.

  CLINICAL
 
    C-CIS  is CITATION's clinical  information system. It  currently consists of
five main components, each of  which can operate independently  or as part of  a
fully integrated system.
 
        C-COM captures and tracks comprehensive patient clinical information and
    routes  that  information among  departments  or systems  in  the healthcare
    organization, enabling providers to  evaluate quality of care,  productivity
    and  cost-effectiveness of services. C-COM  accepts orders from and displays
    the resulting information at any networked PC location where patient care is
    being delivered, such as a nursing  station or even the bedside. C-COM  also
    supports  hand-held, wireless  technology. C-COM is  currently available for
    DOS and Windows and is expected to become available for Windows NT in August
    1996. Depending on  the modules  purchased, its  price range  is $30,000  to
    $80,000.
 
        C-LAB   (marketed  as   LAB  2000   in  the   United  Kingdom)  provides
    comprehensive  laboratory  automation  solutions  for  clinics,  single  and
    multiple  site  hospitals  and  clinical  and  research  laboratories. C-LAB
    automates order entry and dissemination of results and interfaces with  care
    providers'  financial systems. C-LAB consists  of General Lab, Microbiology,
    Anatomical Pathology and Blood Bank submodules. The Blood Bank submodule  is
    licensed by CITATION for use and implementation in C-LAB. C-LAB is currently
    available  for DOS and  is in the  process of being  migrated to Windows NT.
    Depending on the modules purchased, its price range is $85,000 to $800,000.
 
        C-CARE is a patient care management system which is designed to increase
    the productivity  of  nurses and  other  clinicians  and to  assist  in  the
    creation  and  management  of  care  plans  and  clinical  pathways.  C-CARE
    documents variances against  established care plans  and clinical  pathways,
    enabling  care providers to focus on both  improving the quality of care and
    controlling costs. This system enables the healthcare enterprise to allocate
    resources and schedule  procedures and tests  automatically. C-CARE must  be
    used  in  conjunction with  C-COM. C-CARE  is  currently available  for DOS.
    Depending on the modules purchased, its price range is $25,000 to $75,000.
 
        C-RIS (marketed  as  XR2000  in  the  United  Kingdom)  is  a  radiology
    management  system  providing  patient  tracking,  transcription,  radiology
    reporting, auto-fax capabilities, statistical reporting, film management and
    mammography management. C-RIS is currently  available for DOS in the  United
    States  and for Windows  in the United Kingdom  and it is  in the process of
    being migrated to Windows NT. Depending on the modules purchased, its  price
    range is $25,000 to $250,000.
 
        C-MED  is a medication dispensing and inventory control system which can
    increase productivity through the use of tools such as bar-coding to control
    narcotics or floor stock items. C-MED can integrate with a hospital's  other
    information  systems to verify patient status and to provide patient billing
    and laboratory  information.  C-MED also  enables  a single  data  entry  to
    produce  patient  charges,  labels,  profiles,  inventory  control  and drug
    utilization management. The Company licenses  C-MED from a third party,  and
    it  is currently available for DOS.  Depending on the modules purchased, its
    price range is $20,000 to $85,000.
 
  FINANCIAL
 
    CITATION's financial systems consist  of C-FIS (CITATION's registration  and
billing  system),  C-GEN  (CITATION's  general  accounting  system),  and  C-REC
(CITATION's medical and financial records mixed tracking system). These  modules
provide  a  flexible  system  for evaluating  contracts,  controlling  costs and
managing financial information for multiple entity healthcare organizations.
 
        C-FIS handles patient  admissions, discharges and  transfers as well  as
    accounts  receivable, patient  billing and collection  arrangement. C-FIS is
    currently available  for DOS  and is  in the  process of  being migrated  to
    Windows  NT. Depending on the modules  purchased, its price range is $40,000
    to $80,000.
 
        C-GEN has a  general ledger  module providing  budgetary comparisons  as
    well  profit and loss statements for each department or division, or for the
    entire enterprise.  It  has an  accounts  payable module  to  maintain  cash
    management  through disbursement controls. C-GEN  also has the capability to
 
                                       23
<PAGE>
    handle  human  resources  functions,  tracking  authorized  staff  positions
    against  actual labor resources  consumed. C-GEN has  a payroll module which
    assists in  managing labor  costs.  C-GEN is  currently available  for  DOS.
    Depending on the modules purchased, its price range is $40,000 to $80,000.
 
        C-REC  is designed  to help  a medical  records department  meet quality
    assurance, concurrent  review,  and  special study  requirements.  C-REC  is
    currently  available for  DOS and  is in  the process  of being  migrated to
    Windows NT. Depending  on the  modules purchased,  its price  range will  be
    $15,000 to $25,000.
 
  REGISTRATION
 
    CURES,  the Company's  community-wide user  registration system, distributes
demographic and health assessment information across multiple disparate entities
within  healthcare  enterprises  or  IDNs.  CURES  serves  as  a  central   data
repository,  or master  patient index,  for all  patient demographic  and health
status information, streamlining  the intake process  by eliminating  repetitive
registration  questions about medical history and eligibility information. CURES
is capable  of  linking multiple  healthcare  facilities in  a  community  (E.G.
doctors'  offices, hospitals, clinics, nursing  homes, and home health agencies)
as well as multiple  departments within a single  facility, providing each  user
with  access to common demographic  information. CURES can also  serve as a link
between existing information  systems in home  health, physician's offices,  and
other  health facilities, thereby offering a  significant step towards the goals
of a  computerized  patient  record and  the  establishment  of  community-based
healthcare  services. CURES is in final testing  and the Company expects to ship
the product  in  late 1996.  The  Company has  received  orders for  five  CURES
systems.  CURES  will be  available  for Windows  NT.  Depending on  the modules
purchased, its price range will be $25,000 to $250,000.
 
  DECISION SUPPORT
 
    C-MIS, CITATION's decision  support module,  provides healthcare  executives
access  to  financial and  census information,  as  well as  medical, physician,
payor, rate, case  mix and labor  trends. The module  offers report writing  and
word  processing  applications,  enabling  the  user  to  produce  reports tying
together financial and  clinical information. C-MIS  includes multiple  security
levels  to limit access  to sensitive information.  C-MIS is currently available
for DOS.  Depending on  the modules  purchased, its  price range  is $10,000  to
$35,000.
 
SERVICES
 
    Client  service is an important component of the Company's operations. As of
March 31, 1996, the Company employed  57 persons in client services. The  client
services  team  generally  provides  implementation,  application  and  support,
education and consulting services to the Company's clients and primarily employs
medical technologists  and  other  healthcare professionals  in  supporting  and
implementing  healthcare  information  systems.  Instrument  interface,  network
consulting, operating system  and hardware  support are provided  by experts  in
each  area.  Additional  client  services  are  provided  through computer-based
training or formal instructor-led, Company-sponsored ongoing educational courses
and seminars.
 
    In addition, the Company provides comprehensive training for clients at  its
headquarters  near St. Louis. Before  the Company's product becomes operational,
training is  also  provided  at  the client's  location.  The  Company  provides
additional  training at  the client's  request for a  fee. The  Company offers a
maintenance  program  covering  hardware  replacement,  software  upgrades,  and
telephone  consulting  service. Depending  on the  type  of system,  the Company
offers service contracts for periods of  one to five years. Customer support  is
available 24 hours a day.
 
    The Company intends to expand the range of strategic client support and data
interpretation  services it provides  in order to  strengthen relationships with
clients. The Company intends to expand its services to design and configure  the
architecture  of a  client's systems, including  networking, systems integration
and data conversion.  Further, the  Company intends  to provide  advice on  data
analysis to assist care providers in evaluating their operations.

PRODUCT DEVELOPMENT
 
    CITATION  is dedicated to providing  state-of-the-art integrated systems for
healthcare  enterprises.   The  cornerstone   of   CITATION's  system   is   its
long-standing  commitment to  client/server technology.  CITATION's multi-tiered
products are  modular in  nature,  using an  open  architecture that  is  easily
integratable with third party systems as well as other CITATION systems.
 
    CITATION's   current   product  development   efforts   use  object-oriented
programming methodologies. This allows the Company to develop applications based
on reusable  libraries  of  code  that the  Company  believes  results  in  more
cost-effective  and rapid product development cycles. The Company is a Microsoft
Solutions Provider and extensively employs  Microsoft toolsets and standards  in
its product development efforts. The Company believes use of these standards and
tools  facilitates interfacing with other systems and products. The Company also
supports other industry standards  such as HL/7 and  the Novell Netware  Network
Operating System.
 
    Currently,  a majority of  CITATION's products are  available solely on DOS.
C-COM is also available for Windows and is expected to be available for  Windows
NT in August 1996. CURES, which is expected to be shipped in late 1996, will run
on  Windows NT. The Company intends to migrate substantially all of its products
to Windows  NT, which  the  Company expects  will  become the  operating  system
foundation  for a large number of  healthcare enterprises, although there can be
no assurance that  this will be  the case.  While the Company  believes it  will
accomplish  its migration  to Windows NT  in a  timely fashion, there  can be no
assurance that the Company will not experience difficulties that could delay  or
prevent the successful and timely development, introduction and marketing of the
new   Windows  NT  products,  that  such   versions  will  adequately  meet  the
requirements of  the marketplace  or  that the  migration will  be  accomplished
before  demand for existing  versions of the  Company's products slows. Negative
developments in  these  areas  could  have a  material  adverse  effect  on  the
Company's business, results of operations and financial condition.
 
    The  Company plans to expand its product  line to meet the evolving needs of
its clients. The Company continually  evaluates its offerings to determine  what
additional  products or enhancements are  required by the healthcare information
systems marketplace. The  Company develops and  enhances products internally  to
meet  clients' needs, but if the Company can purchase or license proven products
at reasonable  costs it  will do  so  in order  to avoid  the time  and  expense
involved  in developing products. The Company actively seeks out for acquisition
and licensing  other companies  and products  that fit  into CITATION's  overall
product  and technology plan. There is much competition for suitable acquisition
candidates and  there can  be no  assurance that  the Company  will be  able  to
successfully acquire or license additional products.
 
    For  the years ended March 31, 1995 and 1996, CITATION invested $5.3 million
and $4.4 million, respectively, on research  and development. At March 31,  1996
the Company employed 49 persons in research and development. The Company expects
to  continue  to  make  significant  investments  in  research  and development,
however,  there  can  be   no  assurance  that   the  Company's  financial   and
technological  resources  will  permit  it to  develop  or  market  new products
successfully or  respond  effectively  to  technological  changes.  The  Company
expects  to complete the development of the  majority of its Windows and Windows
NT-based products during fiscal  1997. The Company anticipates  that due to  the
nature  of the planned development activities (E.G., product enhancements versus
the significant  development  effort  involved  in porting  software  to  a  new
operating  system), the ratio of software development costs capitalized to total
software development  outlays will  decline  in future  periods as  compared  to
recent years.
 
SALES AND MARKETING
 
    The Company markets its products in the United States, Canada and the United
Kingdom  through  a direct  sales  force under  the  direction of  the Company's
Executive Vice  President  Sales  and  Marketing. As  of  March  31,  1996,  the
Company's  sales force consisted  of 22 employees. In  addition to the Company's
sales force employees, the Company has an 11-person marketing team that promotes
the Company's  products,  participates  in  trade  shows  and  demonstrates  the
Company's products. In addition, members of the Company's development and client
services  departments provide pre-sales  support for the  Company's direct sales
force in  making  presentations to  and  preparing comprehensive  proposals  for
potential customers.
 
                                       25
<PAGE>
    The  Company  intends to  focus its  sales efforts  on selling  larger, more
comprehensive systems to larger hospitals and  IDNs to address a broad range  of
needs.  As part of this strategy, the  Company is cross training its sales force
so that each salesperson will have the  background necessary to sell all of  the
Company's  products. The Company is also planning to increase its sales force in
fiscal 1997.
 
    The  Company  has  a  branch  office  in  the  United  Kingdom  to   enhance
international  marketing. The Company markets  its products through distribution
alliance in the Middle East,  the Far East and  Latin America. For example,  the
Company's  UK office  is providing  support to  El Sief  Development Corporation
(Saudi Arabia) in its efforts to market CITATION products in the Middle East. In
addition, the Company has a  strategic relationship with Microstate  Separations
Plc.  Ltd. ("Microstate"), a healthcare information systems integration based in
Singapore. Microstate  has  agreed to  purchase  the Company's  systems  and  to
install  and support them in other bases,  enhancing the Company's access to the
Asian/Pacific Rim market. In Latin America, CITATION has a strategic arrangement
with Laboratories Para Laboratorios.
 
REGULATION
 
    The Company is  subject to  the general requirements  of the  Food and  Drug
Administration's  regulations for  Class I  Medical Devices  because it produces
C-CIS. The Company complies  with these regulations  and follows Medical  Device
Reporting  guidelines as  well. The  Company decided  not to  internally develop
products (e.g., blood bank  software), at this time,  as doing so would  subject
the  Company to  the pre-market approval  requirements of Section  510(k) of the
Food, Drug and Cosmetic Act.
 
    Additional  legislation  governing  the  dissemination  of  medical   record
information  has been  proposed. The Medical  Records Act,  currently pending in
Congress, would  protect  and regulate  the  confidentiality of  medical  record
information.   The  Medical  Records  Act   would  prohibit  the  disclosure  of
individually identifiable health information, except with the patient's consent.
Without the patient's consent, medical  information could be disclosed only  for
other  limited  purposes,  including  disclosures  to  permit  the  creation  of
nonidentifiable health  information  and  to facilitate  medical  research.  The
Medical  Records Act would preempt most state  laws regarding access to, and the
use and disclosure of, medical record information. If the Medical Records Act is
enacted, compliance with  it could  be costly and  could preclude  or delay  the
introduction of certain new products. The Company is unable to determine at this
time the effect, if any, that these requirements may have on its business.
 
    In  addition,  the healthcare  industry  is subject  to  changing political,
economic and regulatory influences that may affect the procurement practices and
operations of  healthcare providers.  Many lawmakers  have announced  that  they
intend  to propose programs to reform the United States healthcare system. These
programs  may  contain  proposals   to  increase  governmental  involvement   in
healthcare,  lower  reimbursement  rates  and  otherwise  change  the regulatory
environment in which  the Company's  clients operate.  Healthcare providers  may
react  to  these proposals  and the  uncertainty  surrounding such  proposals by
curtailing  or  deferring  investments,   including  those  for  the   Company's
healthcare  information systems. Even if healthcare  providers do not curtail or
defer investments, they may institute cost containment measures in  anticipation
of  regulatory reform or for other reasons. These measures may result in greater
selectivity in the  allocation of  capital funds,  which could  have a  material
adverse  effect  on the  Company's ability  to  sell its  healthcare information
systems and services. The Company cannot predict with any certainty what impact,
if any, such legislative or market-driven reforms might have on its business and
results of operations. There can be no assurance that such proposed changes,  if
adopted,  would not have a material adverse effect on the Company's business and
results of operations.
 
COMPETITION
 
    The market for healthcare information systems is highly competitive. Most of
the  Company's  revenues  are  derived  from  lengthy,  competitive  procurement
processes  managed by sophisticated purchasers  that extensively investigate and
compare the products  offered by the  Company and its  competitors. The  Company
believes that the principal competitive factors in this market are the features,
functions, and capabilities of the information systems, the user's evaluation of
the  ongoing support for the information systems, the potential for enhancements
and future compatible products,  and price. There can  be no assurance that  the
 
                                       26
<PAGE>
Company  will  be able  to  compete successfully  with  respect to  any  of such
factors.  Many  of  the  Company's   current  and  potential  competitors   have
significantly  greater financial, managerial,  development, technical, marketing
and sales resources than the Company and  may be able to devote those  resources
to  develop and  introduce systems more  rapidly than the  Company or healthcare
information systems with significantly greater functionality than, and  superior
overall performance to, those offered by the Company. These competitors may also
be  able to initiate and withstand  significant price decreases more effectively
than the Company. The continuing consolidation of hospitals and other healthcare
providers has resulted in  fewer individual purchasing  decisions, a trend  that
may  favor  larger vendors  with greater  numbers  of hospitals  currently under
contract. Moreover, the healthcare information industry is entering a period  of
consolidation  which  could have  a material  adverse effect  on the  Company by
increasing the size and strength of its competitors.
 
    The Company competes  with a  large number of  other healthcare  information
systems vendors, some of which sell comprehensive systems and some of which sell
products  which compete with only one or more modules of the Company's products.
The Company  believes that  it is  competitive  in the  marketplace due  to  the
functional  capability, sophistication, client/server  architecture and price of
its software systems; the ability of each user to customize the systems to  meet
its  unique needs;  and the high  level of  service the Company  provides to all
clients.
 
PRODUCT LIABILITY
 
    The Company's products may from time to time be involved in the  conveyance,
retrieval  or storage of confidential  data. Improper disclosure of confidential
information as a  result of  an error  in the  Company's healthcare  information
systems  or any failure by the Company's  systems to provide accurate and timely
information could result in claims against  the Company by its clients or  their
patients.  There can  be no assurance  the Company  will not be  subject to such
claims in the future, that such claims will not result in liability in excess of
any insurance coverage maintained  by the Company with  respect to such  claims,
that  insurance  will  cover  such claims  or  that  appropriate  insurance will
continue to be available to the Company at commercially reasonable rates.
 
INTELLECTUAL PROPERTY
 
    The Company regards its products as proprietary and relies on a  combination
of  trade secrecy, contractual provisions, and technical measures to protect its
proprietary rights.  Under  the  Company's  license  agreements,  the  Company's
clients  agree  not  to disclose  sensitive  information about  the  system. The
Company also requires  each employee to  sign a nondisclosure  agreement at  the
commencement of employment. Notwithstanding these safeguards, it is possible for
competitors  of  the Company  to obtain  its  trade secrets  and to  imitate its
products.  Furthermore,  there  can  be  no  assurance  that  others  will   not
independently develop software products similar to those developed or planned by
the  Company.  The Company  has decided  not  to apply  for patent  or copyright
protection for  its  software.  The  Company  believes  that  trade  secret  and
copyright  protection  are  less important  to  the Company's  success  than the
Company's ability to further develop, enhance, and modify its software. However,
the Company has decided to seek trademark protection for the names of certain of
its products in order to avoid confusion in the marketplace.
 
EMPLOYEES
 
    As of March 31, 1996, the Company employed 161 persons. Of these  employees,
49  were involved in product development, 57 in client services, 33 in sales and
marketing and 22 in general administration, clerical and finance. The  Company's
employees  are not  represented by  a labor  union and  the Company's management
believes that its relationship with its employees is good.
 
BACKLOG
 
    The Company sells its products on a purchase order basis, with shipments  of
"turnkey"  systems made shortly after receipt  of executed purchase orders. As a
result, the  level of  backlog at  any  particular time  is not  necessarily  an
indication of future results.

liquidation, dissolution or  winding up  of the  Company, holders  of shares  of
Common Stock are entitled to share ratably in all assets remaining after payment

Preferred Stock, if any. Holders  of Common Stock are  entitled to one vote  for
each  share held on all matters submitted to a vote of the shareholders. Holders

issue one or  more series of  Preferred Stock  and to determine  the rights  and
preferences  of  each  series,  to  the  extent  permitted  by  the  Articles of
Incorporation and applicable law. Among other rights, the Board of Directors may
fix (i)  the  number of  shares  constituting  the series  and  the  distinctive
designation  of the series; (ii)  the annual dividend rate  on the shares of the
series, whether dividends  will be  cumulative, and if  so, from  which date  or
dates;  (iii) whether the series  shall be redeemable, and  if so, the terms and
conditions of such redemption, including the date or dates upon and after  which

conversion or exchange, including the  price or prices or  the rate or rates  of
conversion  or exchange and  the terms of  adjustment, if any;  (vi) whether the
shares of that series shall have voting rights, in addition to any voting rights
provided by law, and if so, the terms of such voting rights; (vii) the rights of
the shares of the series in  the event of voluntary or involuntary  liquidation,
dissolution  or winding up of the Company; and (viii) any other relative rights,
powers, preferences,  privileges, qualifications,  limitations, or  restrictions

shall be identical with each other in  all respects except as to the dates  from
and after which dividends shall cumulate, if cumulative.
 
ANTI-TAKEOVER EFFECTS OF MISSOURI LAW AND ARTICLES OF INCORPORATION AND BY-LAWS
 
    Set  forth  below is  a description  of the  relevant provisions  of Section
351.459 of the Missouri General and  Business Corporations Law, the Articles  of
Incorporation and the By-laws. The descriptions are
 
                                       31
<PAGE>
intended  as a summary only and are  qualified in their entirety by reference to
the Articles of Incorporation  and By-laws, which are  filed as exhibits to  the
Registration  Statement  of which  this  Prospectus is  a  part, and  to Section
351.459 of the Missouri General and Business Corporations Law.
 
    MISSOURI  GENERAL  AND  BUSINESS   CORPORATIONS  LAW  BUSINESS   COMBINATION
PROVISION.  Section 351.459 of the Missouri General and Business Corporation Law
(the "Business Combination Statute"), a statutory provision restricting business
combinations with shareholders who acquire 20% or more of a corporation's voting
stock,  is applicable to the Company because it applies to Missouri corporations
that have a class  of voting stock registered  with the Securities and  Exchange
Commission  (the "Commission")  pursuant to Section  12 of the  Exchange Act and
that have  not elected  to opt  out  of the  Business Combination  Statute;  the
Company has not opted out of the Business Combination Statute.
 
    The  Business  Combination  Statute  prohibits  mergers  and  certain  other
business combination transactions between a publicly held Missouri  corporation,
such  as the Company, and any beneficial owner of 20% or more of the outstanding
voting stock of the Company (an  "Interested Shareholder") for a period of  five
years  after the  date on  which the  latter becomes  an Interested Shareholder,
unless the proposed business combination or the proposed purchase of stock  made
by   such  Interested   Shareholder  on  such   Interested  Shareholder's  stock
acquisition date is approved by the board of directors on or prior to such stock
acquisition date. After such five year restriction, a business combination  with
an Interested Shareholder can only be effected if: (i) such business combination
is  approved by the board of directors prior  to the acquisition of stock by the
Interested Shareholder; or  (ii) a majority  of the holders  of the  outstanding
voting  stock of  the company  (not including  shares beneficially  owned by the
Interested Shareholder) approve such business combination; or (iii) certain fair
price provisions are met by the proposed business combination.
 
    The  Business  Combination  Statute  would  not  prevent  the  holder  of  a
controlling  interest from  exercising control  over the  Company or  preclude a
hostile takeover or  acquisition of  control of  the Company.  It may,  however,
discourage  or make more difficult a hostile takeover or acquisition of control.
Thus, the Business  Combination Statute could  deprive shareholders of  possible
opportunities  to  realize premiums  for  their shares  and  reduce the  risk to
management that it might be displaced by a takeover.
 
    AVAILABILITY  OF  SHARES  OF  CAPITAL  STOCK  FOR  FUTURE  ISSUANCE.     The
availability  for issue  of shares  of Preferred Stock  and Common  Stock by the
Company without further  action by shareholders  (except as may  be required  by
applicable  Nasdaq National Market regulations) could  be viewed as enabling the
Board of Directors to make  more difficult a change  in control of the  Company,
including  by issuing warrants or rights to acquire shares of Preferred Stock or
Common Stock to discourage or defeat unsolicited stock accumulation programs and
acquisition proposals and  by issuing shares  in a private  placement or  public
offering to dilute or deter stock ownership of persons seeking to obtain control
of  the  Company.  The Company  has  no present  plans  to issue  any  shares of
Preferred Stock or Common Stock other than as offered hereby or as  contemplated
under the Stock Option Plans.
 
    REMOVAL OF DIRECTORS ONLY FOR CAUSE AND RELATED PROVISIONS.  The Articles of
Incorporation  provide that Directors may  be removed only for  cause and by the
affirmative vote of the holders of two-thirds of all outstanding stock  entitled
to  vote. This provision, in conjunction with  the provisions of the Articles of
Incorporation authorizing the Board of  Directors to fill vacant  directorships,
may  prevent shareholders  from removing  incumbent Directors  without cause and
filling the resulting vacancies with their own nominees.
 
    CLASSIFIED BOARD  OF DIRECTORS  AND  RELATED PROVISIONS.   The  Articles  of
Incorporation  provide that the Board of Directors is divided into three classes
of Directors serving staggered three-year terms. This classified board provision
will prevent  a party  who acquires  control of  a majority  of the  outstanding
voting  stock from obtaining control of the  Board of Directors until the second
annual shareholders'  meeting  following  the  date  the  acquirer  obtains  the
controlling  interest. The classified  board provision could  have the effect of
discouraging a  potential  acquirer from  making  a tender  offer  or  otherwise
attempting  to  obtain  control  of  the Company  and  could  thus  increase the
likelihood that incumbent Directors will retain their positions.
 
                                       32
<PAGE>
    The Articles of Incorporation provide that  the number of Directors will  be
set  at seven, or such other number as  may be determined in accordance with the
By-laws. The Directors will have the power to change the number of Directors  on
the Board by resolution adopted by vote of a majority of the Board of Directors.
The number of directors is currently set at six.
 
    The foregoing provisions of the Articles of Incorporation and the provisions
described  under  "Description  of  Capital Stock  --  Anti-Takeover  Effects of
Missouri Law and Articles of Incorporation  and By-laws -- Removal of  Directors
Only  for Cause and Related  Provisions" may be changed  only by the affirmative
vote of the holders of two-thirds of the shares of capital stock of the  Company
entitled to vote for directors on such matters at a meeting duly called for such
purpose.
 
    BOARD CONSIDERATION OF ACQUISITION PROPOSALS; OTHER CONSTITUENCIES.  Section
351.347  of the Missouri  General and Business  Corporations Law authorizes, but
does not require,  the Company's  Board of Directors  to consider  a variety  of
factors  and  constituencies  in  addition  to  the  economic  interests  of the
Company's shareholders when exercising its business judgment in connection  with
acquisition  proposals (such  as tender offers,  merger offers and  the like) by
other entities.  The  Articles of  Incorporation  provide that,  in  determining
whether  to  take or  refrain from  taking  any corporate  action, the  Board of
Directors may take into account long-term as well as short-term interests of the
Company  and  its   shareholders,  clients,  employees,   suppliers  and   other
constituencies,  including the effect  on communities in  which the Company does
business. As a consequence, the economic  interests of the shareholders may  not
be  the exclusive factor considered by the Board of Directors in response to any
such proposals.
 
    SHAREHOLDER PROPOSALS.  The By-laws  provide that, if a shareholder  desires
to  submit  a  proposal  at  an annual  or  special  shareholders'  meeting, the
shareholder must submit  written notice to  the Company in  accordance with  the
provisions of Rule 14a-8 promulgated under the Exchange Act.
 
    The  By-laws  also  provide  that,  in  order  for  shareholders  to approve
precatory proposals requesting the Board of Directors to take certain actions, a
majority of the outstanding stock of  the Company entitled to vote thereon  (and
not  of the stock  present at the meeting)  must be voted  for the proposal. The
requirement that  precatory proposals  receive  approval of  a majority  of  the
outstanding shares entitled to vote rather than a majority of the shares present
at  a meeting will  make it more  difficult for shareholders  to obtain the vote
required to  approve such  proposals.  As a  result,  the By-law  provision  may
discourage  or deter a third party from  conducting a solicitation of proxies to
request the Board of Directors to take certain actions.
 
    The By-laws provide that, if a  shareholder desires to nominate persons  for
election as Directors, the shareholder must submit written notice to the Company
at least 120 days and no more than 180 days prior to the anniversary date of the
prior  annual  meeting. Director  nomination notices  must  set forth  the name,
address and  occupation of  the  nominee, certain  other information  about  the
nominee and the shareholder proposing him or her, and other information as would
be required under Regulation 14A of the Exchange Act.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon  completion  of this  offering, the  Company  will have  outstanding an
aggregate of 5,781,936  shares of  Common Stock based  on the  number of  shares
outstanding  at June 30,  1996, including 25,000 shares  of Common Stock offered
hereby  directly   by  the   Company  to   eligible  Company   employees  on   a
non-underwritten  basis and excluding  options to purchase  291,497 shares which
were outstanding as of June 30, 1996. If the Underwriters' over-allotment option
is exercised in full the number of shares of Common Stock outstanding after  the
offering will be 5,991,783. All of these shares will be freely tradeable without
restriction  under the Securities Act of 1933, as amended (the "Securities Act")
or may currently be sold  pursuant to Rule 144  under the Securities Act  ("Rule
144").  If CFB Venture Fund  I, Inc. holds shares  remaining after this offering
with a market value of  at least $1,500,000, it will  have the right to  require
the   Company  to  register  the  shares   under  the  Securities  Act.  If  the
over-allotment is exercised in full, CFB Venture  Fund I, Inc. will not own  any
shares of the Company.
 
    In  general, under  Rule 144  as currently in  effect, a  person (or persons
whose shares are aggregated) who has beneficially owned "restricted  securities"
(as such term is defined in Rule 144) for at least two years, including a person
who  may be deemed an  affiliate of the Company, is  entitled to sell within any
three month period a number of shares  of Common Stock that does not exceed  the
greater  of 1% of the then outstanding shares of Common Stock of the Company and
the average weekly  trading volume of  the Common Stock  on the Nasdaq  National
Market  during the four calendar weeks preceding such sale. Sales under Rule 144
are further subject  to certain  restrictions relating  to the  manner of  sale,
notice  and the availability of current  public information about the Company. A
person who is not an affiliate of the Company as of or at any time during the 90
days preceding a sale and who has beneficially owned shares of Common Stock  for
at  least three  years, is entitled  to sell  such shares without  regard to the
volume limitations, manner of sale  provisions, notice or other requirements  of
Rule 144.
 
    In  addition, under the Company's Stock Option Plans, the Company has issued
options to purchase Common  Stock at prices which  are below current market  and
may  issue options to purchase additional shares  of Common Stock in the future.
At June  30, 1996,  options to  purchase  291,497 shares  of Common  Stock  were
outstanding  of  which  options  to  purchase  283,497  shares  were immediately
exercisable and  options to  purchase 4,000  shares will  become exercisable  on
September  26, 1996. An  additional 21,684 shares of  Common Stock are available
for  future  grants  under  the  Stock  Option  Plans.  The  Company  has  filed
registration  statements on Form S-8 to permit the shares acquired upon exercise
of options to be freely tradable or sold pursuant to Rule 144.
 
    The Company, its directors, executive officers and the Selling Shareholders,
holding an  aggregate of  2,125,528  shares of  Common Stock  (excluding  shares
offered hereby other than the shares subject to the Underwriters' over-allotment
option),  have entered into lockup agreements  with the Underwriters pursuant to
which such stockholders  have agreed  not to sell  or otherwise  dispose of  any
shares  of  Common  Stock for  a  period of  120  days  after the  date  of this
Prospectus without the  prior written consent  to Volpe, Welty  & Company.  Upon
expiration  of the  lockup period, these  shares will be  eligible for immediate
sale, subject in certain cases to  volume and other limitations under Rule  144.
See "Underwriting."
 
    No  prediction can be  made as to the  effect, if any,  that market sales of
shares or the  availability of shares  for sale  will have on  the market  price
prevailing  from time to time.  Sales of substantial number  of shares of Common
Stock could adversely affect prevailing market prices.
 
                           COMPANY EMPLOYEE OFFERING
 
    Of the shares of Common Stock offered hereby, the Company is offering 25,000
shares of  Common  Stock  (the  "Employee  Shares")  to  its  full-time  Company
employees  who are presently and  for at least six  months have been employed by
the Company (the "Employee Offerees"). The  Employee Shares will be offered  and
sold to eligible Employee Offerees on a non-discriminatory basis at the Price to
Public  less the amount  of Underwriting Discounts  and Commissions. The minimum
number of Employee Shares  that may be  purchased by an  Employee Offeree is  25
shares.  Employee  Offerees  must  advise the  Company  whether  they  desire to
purchase any of the Employee Shares  not later than twenty-four hours after  the
date of this
 
                                       34
<PAGE>
Prospectus.  Any Employee Shares not purchased  by Employee Offerees will not be
offered or sold to the public. In the event that the offering by the Company  of
Employee  Shares is over-subscribed,  each subscribing Employee  Offeree will be
sold a number of  Employee Shares equal to  his or her pro  rata portion of  the
25,000  Employee Shares available  for sale based on  the relationship which the
number of Employee Shares subscribed for  by such Employee Offeree bears to  the
total  number of  Employee Shares subscribed  for by all  Employee Offerees. The
offering to the public  pursuant to this Prospectus  is not contingent upon  any
minimum  number  of  Employee  Shares  being  sold.  The  Underwriters  are  not
responsible for and are not involved in any manner with the offering and sale of
the Employee Shares and  the Underwriters will not  receive any compensation  or
reimbursement in respect of the sale of the Employee Shares.
 
    Each  Employee Offeree who purchases Employee  Shares is required to include
in his  or her  gross income  in  the year  of purchase,  with respect  to  each
Employee  Share purchased by such  Employee Offeree, the excess,  if any, of the
fair market value of an Employee Share (determined at the time of transfer) over
the amount  paid  by such  Employee  Offeree. This  amount  will be  subject  to
applicable  income,  employment  and  other  withholding  taxes.  Any subsequent
appreciation or depreciation in the value of such Employee Share generally  will
be  taxable as capital gain or loss on an exchange or other taxable disposition.
This summary of  Federal income  tax consequences  to Employee  Offerees is  not
intended  to  be a  complete  summary of  such  tax consequences.  Further, this
summary does  not  cover other  tax  consequences, including  state  income  tax
consequences. Accordingly, Employee Offerees are urged to consult with their own
tax advisors concerning the purchase of Employee Shares.

</TABLE>
 
    The Underwriting Agreement provides that the obligations of the Underwriters
are  subject  to  certain conditions  precedent,  including the  absence  of any
material adverse change  in the Company's  business and the  receipt of  certain
certificates,  opinions  and  letters  from  the  Company  and  its  counsel and
independent auditors. The nature  of the Underwriters'  obligation is such  that
they  are committed to purchase all shares of Common Stock offered hereby if any
of such shares are purchased.
 
    The Representatives have advised the  Company that the Underwriters  propose
to  offer the  shares of Common  Stock to the  public at the  offering price set
forth on the cover page of this Prospectus and to certain dealers at such  price
less  a concession of not in excess of $        per share, of which $        may
be reallocated to other dealers. After the offering, the public offering  price,
concession  and reallowance to dealers may be reduced by the Representatives. No
such reduction shall change the amount of proceeds to be received by the Company
as set forth on the cover page of this Prospectus.
 
    The Company and the Selling Shareholders have granted to the Underwriters an
option, exercisable  within  30 days  after  the  date of  this  Prospectus,  to
purchase  up  to  an additional  209,847  and  200,000 shares  of  Common Stock,
respectively, at  the  same price  per  share as  the  Company and  the  Selling
Shareholders  receive for the  2,732,312 shares of  Common Stock offered hereby,
solely to  cover over-allotments,  if any.  If the  Underwriters exercise  their
over-allotment  option,  the  Underwriters  have  severally  agreed,  subject to
certain conditions, to purchase approximately  the same percentage thereof  that
the  number of shares of Common Stock to  be purchased by each of them, as shown
in the foregoing table,  bears to the 2,732,312  shares of Common Stock  offered
hereby.  The  Underwriters may  exercise  such option  only  to cover  the over-
allotments in connection with the sale  of the 2,732,312 shares of Common  Stock
offered hereby.
 
    Each  of the  Company's directors, certain  officers of the  Company and the
Selling Shareholders  have  agreed not  to  offer,  sell, contract  to  sell  or
otherwise dispose of Common Stock or securities convertible into or exchangeable
for, or any rights to purchase or acquire, Common Stock for a period of 120 days
following  the date  of this  Prospectus, without  the prior  written consent of
Volpe, Welty & Company. The Company also has agreed not to offer, sell, contract
to sell or otherwise  dispose of any  shares of Common  Stock or any  securities
convertible  into or  exchangeable for,  or any  rights to  purchase or acquire,
Common Stock for  a period of  120 days  following the date  of this  Prospectus
without  the prior  written consent  of Volpe, Welty  & Company,  except for the
offering of  25,000 shares  of  Common Stock  to  certain Company  employees  as
described  on  the cover  page of  this Prospectus  and under  "Company Employee
Offering" and the granting
 
                                       36
<PAGE>
of options pursuant to the Company's existing Stock Option Plans. Volpe, Welty &
Company, in its discretion, may waive the foregoing restrictions in whole or  in
part, with or without a public announcement of such action.
 
    The  Company is  offering 25,000  shares of  Common Stock  hereby to certain
Company employees as described  on the cover page  of this Prospectus and  under
"Company  Employee Offering." The offering of  Employee Shares by the Company is
not being underwritten by the Underwriters and will not be subject to the  terms
and  conditions of the Underwriting Agreement. The Underwriters will not receive
any compensation or reimbursement in connection  with the offer or sale of  such
shares.  Any of such shares of Common Stock not purchased by such employees will
not be offered or sold to the public.
 
    The offering of the underwritten shares is made for delivery when, as and if
accepted by  the Underwriters  and  subject to  prior  sale and  to  withdrawal,
cancellation  or modification of  the offering without  notice. The Underwriters
reserve the right to reject an order for  the purchase of shares in whole or  in
part.
 
    In  general,  the  rules  of the  Securities  and  Exchange  Commission (the
"Commission") will prohibit the Underwriters from making a market in the  Common
Stock  during the "cooling off" period immediately preceding the commencement of
sales in  the offering.  The Commission  has, however,  adopted exemptions  from
these  rules that permit  passive market making  under certain conditions. These
rules permit  an  underwriter  to continue  to  make  a market  subject  to  the
conditions,  among others, that its  bid not exceed the  highest bid by a market
maker not connected  with the offering  and that  its net purchases  on any  one
trading  day not exceed prescribed limits. Pursuant to these exemptions, certain
Underwriters, selling group members (if any) or their respective affiliates  may
have  engaged in passive market making in  the Company's Common Stock during the
cooling off period.
 
    The Company  and  the Selling  Shareholders  have agreed  to  indemnify  the
Underwriters   and  their  controlling   persons  against  certain  liabilities,
including liabilities  under the  Securities  Act of  1933,  as amended,  or  to
contribute  to  payments the  Underwriters may  be required  to make  in respect
thereof.
 
                                 LEGAL MATTERS
 
    The validity of  the shares  of Common Stock  being offered  hereby will  be
passed  upon for the Company by Mayer, Brown & Platt, Chicago, Illinois, special
counsel to the Company, which  may rely, as to matters  of Missouri law, on  the
opinion  of Suelthaus & Walsh, P.C.,  St. Louis, Missouri. Certain legal matters
will be passed upon  for the Underwriters by  Sachnoff & Weaver, Ltd.,  Chicago,
Illinois.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Shareholders and Board of Directors of CITATION Computer Systems, Inc.
 
    In  our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of cash flows and of shareholders' equity
present fairly, in all material respects, the consolidated financial position of
CITATION Computer Systems, Inc. and its subsidiaries at March 31, 1996 and 1995,
and the results of their operations and  their cash flows for each of the  three
years  in the period ended March 31, 1996, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of  the
Company's  management;  our responsibility  is to  express  an opinion  on these
financial statements  based on  our audits.  We conducted  our audits  of  these
statements  in  accordance  with  generally  accepted  auditing  standards which
require that we plan and perform the audit to obtain reasonable assurance  about
whether  the financial  statements are free  of material  misstatement. An audit
includes examining,  on  a  test  basis, evidence  supporting  the  amounts  and
disclosures  in the  financial statements,  assessing the  accounting principles
used and significant estimates  made by management,  and evaluating the  overall
financial   statement  presentation.  We  believe  that  our  audits  provide  a
reasonable basis for the opinion expressed above.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    The policies utilized  by the Company  in the preparation  of the  financial
statements  conform  to generally  accepted  accounting principles,  and require
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities at the date of the financial statements and the  reported
amounts  of revenues  and expenses during  the reporting  period. Actual amounts
could differ from these estimates.
 
    The significant accounting  policies followed by  the Company are  described
below:
 
    OPERATIONS
 
    CITATION  designs, develops, markets  and services client/server information
systems for the healthcare industry. The Company's products focus on three  main
areas: clinical, administrative/ financial, and community registration.
 
    INVENTORIES
 
    Inventories  are valued at  the lower of  cost, determined on  the first in,
first out basis, or market.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment is recorded  at cost. Major renewals and  betterments
are  capitalized  while maintenance  and  repairs are  expensed  currently. When
property is sold  or otherwise  disposed of,  the related  cost and  accumulated
depreciation  are removed from the respective accounts,  and any gain or loss on
disposition is credited or charged to income.

    The Company provides for depreciation of property and equipment by  charging
against  earnings amounts sufficient to amortize the cost of the properties over
the estimated useful lives generally using straight-line methods. The  estimated
useful life of the assets is as follows:

    REVENUE RECOGNITION
 
    Revenue from the sale of computer systems is recognized upon shipment to the
customer  providing that no significant vendor obligations remain and collection
of the related  receivable is  deemed probable.  Costs and  expenses related  to
installation  of the computer  equipment and software  system, training customer
personnel, and provision for  warranties offered are  estimated and recorded  as
cost of sales when the related revenue is recognized.
 
    Revenue  from the  sale of  additional hardware  and additional  software is
recognized upon  shipment.  Costs  and  expenses associated  with  the  sale  of
additional  hardware  and  software are  recorded  when the  related  revenue is
recognized. Revenue  related  to  product  warranties  and  maintenance  service
contracts  is recognized  ratably over  the term  of the  contract period. Sales
returns are treated as reductions to net system sales and service revenues.
 
    COST OF SALES
 
    For purposes of estimating the cost of sales related to service revenue, the
Company includes all  of its  customer service  expenses plus  an allocation  of
certain other expenses based upon estimates made by management.
 
    SOFTWARE DEVELOPMENT COSTS
 
    Certain  costs incurred in developing  software products are capitalized and
amortized on a  product-by-product basis  using the  greater of  the ratio  that
current  gross revenues for a product bear to the current and anticipated future
gross revenues for that product or  the straight-line method over the  estimated
three to five year economic life of the products. The costs consist of salaries,
computer  expenses and other overhead costs  directly related to the development
and/or major enhancement of  software products. Such  costs are capitalized,  to
the  extent  they  are  recoverable  through future  sales,  from  the  time the
products' technological feasibility is established up to its general release  to
customers. Costs incurred before or after this period are expensed as incurred.
 
    RESEARCH AND DEVELOPMENT COSTS
 
    Research and development costs are charged to expense as incurred.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    INCOME TAXES
 
    The  Company utilizes the  liability method of  accounting for income taxes.
Under the liability method,  deferred income taxes are  determined based on  the
difference  between  the  financial  statement  and  tax  bases  of  assets  and
liabilities using  enacted  tax  rates in  effect  in  the years  in  which  the
differences are expected to reverse. Such temporary differences result primarily
from  using  different  methods  to accrue  certain  expenses  and  to calculate
capitalization of software  development costs  for financial  and tax  reporting
purposes.  Deferred tax expense represents the  change in the deferred tax asset
or liability.
 
    EARNINGS PER COMMON AND COMMON EQUIVALENT SHARE
 
    Earnings per common and  common equivalent share  is determined by  dividing
net  income by the aggregate weighted average number of common shares and common
share  equivalents  outstanding  during  each  period  presented.  Common  share
equivalents  consist  of common  stock which  may be  issuable upon  exercise of
outstanding stock  options  (using  the  treasury  stock  method),  except  when
antidilutive.
 
    The  weighted average number of shares used in computing earnings per common
and common equivalent share are as follows:

    FOREIGN CURRENCY TRANSLATION
 
    The asset  and liability  accounts  of the  Company's foreign  division  are
translated  at  the  year-end exchange  rate.  Revenue and  expense  amounts are
translated  at  monthly  average  exchange  rates.  The  resulting   translation
adjustment  is recorded as a separate component of shareholders' equity. Foreign
currency transaction gains and  losses are included  in earnings when  incurred.
Such foreign currency transaction gains and losses were not material for each of
the three years in the period ended March 31, 1996.
 
    CASH AND CASH EQUIVALENTS
 
    Cash  and cash equivalents  includes all highly  liquid investments, such as
money-market accounts and short-term discount  notes, with an original  maturity
of three months or less.
 
    PRINCIPLES OF CONSOLIDATION
 
    The  consolidated financial statements  include the accounts  of the Company
and its wholly owned subsidiaries. All significant intercompany transactions and
balances have been eliminated.
 
    DIRECTORS' FEES
 
    During the year  ended March  31, 1995,  the Company  adopted the  Directors
Common  Share Plan ("Directors'  Plan") whereby certain  non-employee members of
the Board  of  Directors ("Directors")  may  receive all  or  a portion  of  the
Directors'  fees in the form of Company common stock in lieu of cash. During the
years ended March  31, 1995 and  1996, 5,433  and 4,959 shares  of common  stock
valued  at $37 and  $31, respectively, were  issued to such  Directors under the
Directors' Plan.
 
3.  OFFICE CONSOLIDATION AND RELOCATION
    In June  1995, the  Company decided  to consolidate  the operations  of  its
Madison, Wisconsin, facility into its St. Louis, Missouri, headquarters. Charges
of    $1,000,   $58   and    $322   were   recorded    in   the   first,   third

and fourth quarters, respectively,  of the fiscal year  ended March 31, 1996  to
provide  for the costs of the consolidation of facilities, settlement of related

</TABLE>
 
    All expenses associated  with the office  consolidation and relocation  were
recorded  during the fiscal  year ended March  31, 1996, and  no material future
costs are  expected.  With  the  exception  of  the  asset  write-offs  totaling
approximately $90, all costs resulted in cash payments.
 
4.  RESTRUCTURING OF OPERATIONS
    During  the fourth  quarter of  the fiscal  year ended  March 31,  1995, the
Company initiated various activities to  restructure its operations in order  to
reduce its cost structure and remain competitive.
 
    Restructuring  activities resulted in  net charges of  $3,426 which included
$2,801 related to  the write-off  of capitalized software  costs, inventory  and
intangible   assets   associated  with   discontinued  product   lines,  certain
maintenance contracts and intangible assets associated with the CPS  acquisition
and  $625 for severance and related benefit costs associated with changes in the
Company's executive  management. With  the exception  of the  asset  write-offs,
these restructuring charges resulted in cash outlays.
 
    Accrued  restructuring costs totaling $292 were  paid during the fiscal year
ended March 31, 1996, and no additional costs were incurred or are expected.
 
5.  CONCENTRATION OF CREDIT RISK
    The Company  generates revenue  primarily through  sales to  the  healthcare
industry  located  throughout  the  United States.  Due  to  this concentration,
substantially all receivables  at March 31,  1995 and 1996  are from  healthcare
institutions  which may be similarly affected by changes in economic, regulatory
or other conditions.
 
    The Company  performs  ongoing  credit  evaluations  of  its  customers  and
generally  does  not  require  collateral. The  Company  maintains  reserves for
potential  credit  losses  and  such   losses  have  been  within   management's
expectations.
 
    The  Company  invests  its  excess cash  in  deposits  with  major financial
institutions, in U.S. government  agency securities and  in commercial paper  of
companies  with strong credit ratings.  Generally, the investments mature within
90 days  and,  therefore,  are subject  to  little  risk. The  Company  has  not
experienced losses related to these investments.

7.  DEBT
    Long-term  debt consists of  bank notes payable  with interest rates ranging
from 8.09% to 8.75% due through March 2000. Long-term debt at March 31, 1995 and
1996, was $660 and $593, respectively.
 
    As of March  31, 1996, the  Company had a  line of credit  agreement with  a
bank.  The line of credit allows the Company to borrow up to $1,000 through July
31, 1996, with  interest at the  bank's prime  rate (8.25% at  March 31,  1996).
There  were  no borrowings  outstanding under  the line  of credit  agreement in
effect at March 31, 1996.
 
    The line  of credit  and the  notes  payable are  secured by  the  Company's
accounts  receivable, inventory,  equipment and  general intangible  assets. The
respective agreements require that certain minimum net worth and leverage  ratio
requirements  be maintained by  the Company. The Company  was in compliance with
these requirements at March 31, 1996.
 
    The aggregate maturities of long-term debt are as follows:

9.  STOCK OPTIONS AND WARRANTS
    On April 20,  1992, the  board of  directors and  shareholders approved  the
adoption of the 1992 Employee Incentive Stock Option Plan which provides for the
issuance  of up  to 148,347  stock options  to executive  officers or  other key
employees of the Company.
 
    On October 13, 1993, the board of directors adopted an amendment to the 1992
Employee Incentive Stock Option Plan which increased the number of stock options
available for  issuance to  executive officers  or other  key employees  of  the
Company by 200,000.
 
    The Company's incentive stock option plan allows participation, with certain
restrictions,  by  all full-time  employees with  one  year of  service. Options
granted allow employees  to purchase  shares of  the Company's  common stock  at
prices  not less  than the fair  market value  of the stock  at the  date of the
grant. Options which have been granted under the plan are exercisable during the
employment of the grantee  or at specified  time intervals. Outstanding  options
expire between 1995 and 2005.

    Paid-in  capital is  credited with  proceeds received  in excess  of the par
value of shares  issued under  the stock  option plan.  No charges  are made  to
income  in accounting  for this plan  due to  the options being  granted with an
exercise price at or  above the fair value  of the common stock  on the date  of
grant.
 
    At  March 31, 1996, 234,997 options outstanding were exercisable. During the
years  ended  March  31,  1997  and  1998,  an  additional  60,500  and   4,000,
respectively,  options outstanding  will become  exercisable. Options  on 21,684
shares were available for grant under  the 1992 Employee Incentive Stock  Option
Plan at March 31, 1996.
 
    NEW ACCOUNTING STANDARDS
 
    In  October 1995, the Financial  Accounting Standards Board issued Statement
of  Financial  Accounting   Standards  No.  123   "Accounting  for   Stock-Based
Compensation"  ("FAS 123") which addresses accounting for stock option, purchase
and award plans. FAS 123 specifies that companies utilize either the "fair value
based method" or the  "intrinsic value based method"  for valuing stock  options
granted.  The Company will adopt FAS 123  during the year ending March 31, 1997,
and expects to  utilize the  "intrinsic value  based method"  for valuing  stock
options granted. The Company anticipates that when adopted, FAS 123 will have no
material  effect on its consolidated  financial position or consolidated results
of operation.
 
10. PROFIT AND SAVINGS INCENTIVE PLANS
    CITATION  maintains  a   Retirement  Savings   Plan  for   the  benefit   of
substantially  all CITATION employees. Employee  contributions may range from 1%
to 15% of compensation,  and CITATION matches a  discretionary percentage of  an
employee's  contribution. The match will be based on the employee's contribution
up to 6% of the employee's compensation.
 
    For the plan year ended December 31, 1995, the matching contribution was 25%
of such contributions, and was paid in the form of cash the first three quarters
of the year and in the form of  Company stock for the fourth quarter. It is  the
Company's current intention to continue to make the matching contribution in the
form  of Company stock.  Employees are 100% vested  as to employee contributions
and are  vested as  to  employer contributions  at the  rate  of 20%  per  year,
beginning in the second year of service.
 
    For  the years  ended March  31, 1994, 1995  and 1996,  the Company recorded
expense of approximately $66, $82 and $66, respectively, relating to this plan.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    (a)  The Missouri  General and  Business Corporations  Law (Section 351.355)
gives Missouri corporations broad powers  to indemnify their present and  former
directors  and officers  and those  of affiliated  corporations against expenses
incurred in the defense of any lawsuit to which they are made parties by  reason
of  being  or  having been  such  directors  or officers,  subject  to specified
conditions and exclusions, gives a director or officer who successfully  defends
an  action the right to be so  indemnified, and authorizes the registrant to buy
directors' and  officers'  liability  insurance.  Such  indemnification  is  not
exclusive  of any other rights to which  those indemnified may be entitled under
any articles  of  incorporation, by-laws,  agreement,  vote of  shareholders  or
disinterested directors or otherwise.
 
    (b)  Article XI of the Articles  of Incorporation of the registrant permits,
and Article VII of the By-laws of the registrant provides for indemnification of
directors and officers, and  permits the Board of  Directors to grant  employees
and agents indemnification, to the fullest extent permitted by law.
 
    (c)  Reference is made to Section 11 of the Underwriting Agreement (the form
of which is included as Exhibit 1 to this Registration Statement) for provisions
regarding the indemnification under certain circumstances of the registrant, its
directors and certain of its officers by the Underwriters.

ITEM 17.  UNDERTAKINGS
 
    (a) Insofar as indemnification for liabilities arising under the  Securities
Act  of 1933, as amended (the "Securities  Act"), may be permitted to directors,
officers and controlling persons  of the registrant  pursuant to the  provisions
described  under Item  15 above, or  otherwise, the registrant  has been advised
that  in  the   opinion  of   the  Securities  and   Exchange  Commission   such
indemnification is against public policy as expressed in the Securities Act, and
is,  therefore, unenforceable.  In the  event that  a claim  for indemnification
against such liabilities (other than the  payment by the registrant of  expenses
incurred  or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities  being
registered, the registrant will, unless in the opinion of its counsel the matter
has  been settled  by controlling  precedent, submit  to a  court of appropriate
jurisdiction the question whether such  indemnification by it is against  public
policy  as expressed in such  Securities Act, and will  be governed by the final
adjudication of such issue.
 
    (b) For determining any liability  under the Securities Act, the  registrant
