                                   PROSPECTUS
                                       OF
                                 HBO & COMPANY
                           UP TO 3,981,407 SHARES OF
                                  COMMON STOCK

   
    This  Proxy Statement/Prospectus is being furnished  to holders of shares of
Common Stock, $.001 par value per  share ("CliniCom Common Stock"), of  CliniCom
Incorporated,  a  Delaware corporation  ("CliniCom"),  as a  proxy  statement in
connection with  the  solicitation of  proxies  by  the Board  of  Directors  of
CliniCom  (the "CliniCom Board") for use  at the special meeting of stockholders
of CliniCom to  be held on  Saturday, September  30, 1995, at  The Courtyard  by
Marriott,  4710  Pearl  East  Circle,  Boulder,  Colorado  80301  at  10:00 a.m.
(Mountain Time), and at any adjournment or postponement thereof (the "Meeting").
    

   
    This Proxy Statement/Prospectus  also constitutes  the prospectus  of HBO  &
Company, a Delaware corporation ("HBOC"), with respect to up to 3,981,407 shares
(less  the aggregate  amount of  fractional shares  which are  paid in  cash) of
Common Stock, $.05  par value  per share  of HBOC  ("HBOC Common  Stock") to  be
issued  in connection with the  merger (the "Merger") of  CliniCom with and into
HBO &  Company  of Georgia,  a  Delaware corporation  which  is a  wholly  owned
subsidiary of HBOC ("HBOC-GA"), in exchange for all of the outstanding shares of
CliniCom  Common Stock. In the Merger, subject  to the terms of the Agreement of
Merger, dated as of July 14, 1995, among CliniCom, HBOC and HBOC-GA (the "Merger
Agreement"), each outstanding share of CliniCom  Common Stock and each right  to
acquire  a share of CliniCom  Common Stock, will be  converted into the right to
receive .4 of a share of HBOC Common Stock (the "Exchange Ratio"). As more fully
discussed herein,  CliniCom  will have  the  right  but not  the  obligation  to
terminate the Merger Agreement in the event the average of the closing prices on
the  Nasdaq Stock Market National Market  ("NASDAQ-NM") of the HBOC Common Stock
is less than $50.00 for any period of twenty consecutive trading days ending  on
any  date  prior  to  the second  trading  day  prior to  the  Closing  Date (as
hereinafter defined).  In addition,  it  is a  condition  to the  obligation  of
CliniCom to close the transactions contemplated by the Merger Agreement that the
average  of the closing prices on the NASDAQ-NM of the HBOC Common Stock for the
ten consecutive  trading days  ending on  the second  trading day  prior to  the
Closing  Date  not  be less  than  $50.00.  The CliniCom  Board  may  waive this
condition.
    

    Outstanding and unexercised  options to purchase  shares of CliniCom  Common
Stock  will be assumed by  HBOC upon the completion of  the Merger such that the
holder will have the right to purchase the number of shares of HBOC Common Stock
into which the  shares of CliniCom  Common Stock subject  to such options  would
have been converted in the Merger.

   
    As  a result of  the Merger, holders  of shares of  CliniCom Common Stock or
rights to acquire shares  of CliniCom Common Stock  will receive shares of  HBOC
Common Stock, which in the aggregate will represent up to 3,981,407 shares (less
the  aggregate amount of any  fractional shares which are  paid in cash) of HBOC
Common Stock. Shares of HBOC Common  Stock are currently approved for  quotation
on the NASDAQ-NM. On August 31, 1995, the reported closing sale price of a share
of  HBOC Common Stock on the NASDAQ-NM was $55.00, and the reported closing sale
price of a  share of CliniCom  Common Stock  on the NASDAQ-NM  was $21.50.  This
Proxy Statement/Prospectus and the related Notice of Special Meeting and form of
proxy  are first being mailed to stockholders  of CliniCom on or about September
1, 1995.

CliniCom  system  is  an integrated  software/hardware  solution  which provides
access to detailed clinical information through an open-systems architecture,  a
relational  database and a  wireless network. The system  is designed to enhance
the efficiency of  an entire  healthcare provider network  by unifying  clinical
information  from  all  areas with  a  consistent user  interface  and providing
on-line access to patient care  information. CliniCom's modular software  allows
healthcare  organizations to purchase a base  system and add software modules as
requirements change and new products are released. CliniCom continually  expands
the scope and functionality of its products to address the changing needs of the
evolving  healthcare market.  Currently, CliniCom's  primary market  consists of
approximately 5,300  hospitals  in  the  United  States  (excluding  psychiatric

Certificates for exchange and/or payment

                                       7

purposes  of  Rule  145  under  the  Securities  Act  will  be  subject  to  the
restrictions  imposed by such rule. In accordance with Rule 145, an affiliate of
CliniCom receiving HBOC  Common Stock  issued in the  Merger may  not sell  such
shares  except pursuant to the  volume and manner of  sale limitations and other
requirements  specified  therein  or  pursuant  to  an  effective   registration
statement  under the Securities  Act. See "The  Merger Proposal --  Terms of the
Merger -- Limitations  on Transferability  of HBOC Common  Stock." In  addition,
certain  CliniCom affiliates are subject to  certain restrictions on transfer of
both CliniCom  Common Stock  prior  to, and  HBOC  Common Stock  following,  the
Effective Date of the Merger to ensure pooling treatment of the transaction.
    

   
    CONDITIONS;  WAIVER.  The obligations  of HBOC and HBOC-GA  on the one hand,
and of CliniCom, on the other hand, to consummate the Merger are contingent upon
the satisfaction  or waiver  of certain  conditions, including  approval of  the
Merger by holders of the requisite number of shares of CliniCom Common Stock. It
is  a condition  of the  obligation of CliniCom  to consummate  the Merger that,
unless waived, the average of the closing prices of the HBOC Common Stock on the
NASDAQ-NM for the ten consecutive trading days ending on the second trading  day
prior  to the Closing Date be not less  than $50.00. See "The Merger Proposal --
Terms of the Merger -- Conditions; Waiver."
    

    HART-SCOTT-RODINO.   The  Merger  is  subject to  the  requirements  of  the
Hart-Scott-Rodino  Antitrust Improvements  Act of  1976, as  amended (the "H-S-R
Act"), which provides that certain  transactions (including the Merger) may  not
be  consummated until  certain information has  been furnished  to the Antitrust
Division of the Department of Justice (the "Antitrust Division") and the Federal
Trade Commission (the "FTC") and  certain waiting period requirements have  been
satisfied.  HBOC and CliniCom  filed the required  information and material with
the Antitrust Division and the FTC on July 21, 1995 and were notified that  they
had  been granted early termination of the waiting period on August 4, 1995. See
"The Merger Proposal -- Terms of the Merger -- Hart-Scott-Rodino."

    TERMINATION.  The Merger  Agreement may be terminated  at any time prior  to
the  Effective  Time of  the  Merger by:  (i) mutual  consent  of the  Boards of
Directors of  HBOC  and  CliniCom;  (ii)  HBOC-GA,  in  the  event  of  material
condemnation,  destruction,  loss  or  damage  of  CliniCom;  (iii)  HBOC-GA  or
CliniCom, after the earlier to occur of November 15, 1995, and the date that  is
twenty-four  (24) business days following the date the Registration Statement on
Form S-4 is declared effective  by the Commission, if  the other party fails  to
fulfill  any of its  conditions, unless fulfillment has  been made impossible by
the party seeking termination; (iv) CliniCom, if, in the good faith exercise  of
its  fiduciary  duties to  the  stockholders of  CliniCom  in the  context  of a
proposal to acquire CliniCom by another  party, the CliniCom Board decides  that
such  termination is required;  or (v) CliniCom,  if the average  of the closing
prices of  the HBOC  Common Stock  on the  NASDAQ-NM for  any period  of  twenty
consecutive  trading days  ending on  any date prior  to the  second trading day
prior to the Closing Date is less than $50.00. See "The Merger Proposal -- Terms
of the Merger -- Termination."

ACCOUNTING TREATMENT

    It is a condition of the closing  of the Merger that the parties shall  have
received  letters  from their  independent  accountants advising  them  that the
Merger may  be  accounted  for  under  the  "pooling  of  interests"  method  of
accounting in accordance with generally accepted accounting principles. See "The
Merger Proposal -- Accounting Treatment."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

    The Merger is intended to qualify as a "tax-free reorganization" for federal
income  tax purposes. Davis,  Graham & Stubbs, L.L.C.,  counsel to CliniCom, has
advised CliniCom, subject  to the receipt  of certain customary  representations
and   assumptions,   that   no   gain   or   loss   would   be   recognized   by

                                       8
<PAGE>
CliniCom or by  holders of  CliniCom Common Stock  on the  exchange of  CliniCom
Common Stock for HBOC Common Stock (except with respect to cash received in lieu
of  fractional shares). See  "The Merger Proposal --  Certain Federal Income Tax
Consequences." EACH HOLDER OF CLINICOM COMMON  STOCK IS URGED TO CONSULT HIS  OR
HER TAX ADVISOR TO DETERMINE THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO SUCH
HOLDER.

NO APPRAISAL RIGHTS

    The  holders of  shares of  CliniCom Common  Stock will  not be  entitled to
appraisal rights pursuant to Section 262 of the Delaware General Corporation Law
(the "DGCL")  in connection  with the  Merger. See  "The Merger  Proposal --  No
Appraisal Rights."

                                     OTHER

INTERESTS OF CERTAIN PERSONS

   
    SECURITY  OWNERSHIP OF DIRECTORS  AND EXECUTIVE OFFICERS.   As of the Record
Date, directors and  executive officers  of CliniCom and  their affiliates  were
beneficial  owners  of 3,421,070  outstanding  shares of  CliniCom  Common Stock
representing approximately  39% of  the total  issued and  outstanding  CliniCom
Common  Stock. Holders  of all  of such shares  have advised  CliniCom that they
presently intend to vote  or direct the  vote of all  shares of CliniCom  Common
Stock  over which  they have  voting control in  favor of  the Merger Agreement.
Directors and executive officers of HBOC and their affiliates beneficially owned
approximately 4.4% of the outstanding shares  of HBOC Common Stock at August  1,
1995. See "Interests of Certain Persons in Each of HBOC and CliniCom."
    

    INTERESTS  OF CERTAIN PERSONS IN  MATTERS TO BE ACTED  UPON.  In considering
the Merger, stockholders  of CliniCom should  be aware that  certain members  of
management  and the  CliniCom Board  have interests  in the  Merger that  are in
addition to,  or  different from,  the  interests of  stockholders  of  CliniCom
generally.  See "Interests of  Certain Persons in  Each of HBOC  and CliniCom --
Interests of Certain Persons in Matters to be Acted Upon."

COMPARISON OF STOCKHOLDER RIGHTS

    HBOC and CliniCom are each incorporated under Delaware law. For a summary of
material differences between the rights of holders of shares of each of CliniCom
Common Stock and  HBOC Common  Stock, see "Comparison  of Rights  of Holders  of
Shares of Each of HBOC Common Stock and CliniCom Common Stock."

CERTAIN MARKET INFORMATION

                                  RISK FACTORS

    IN  ADDITION TO THE OTHER INFORMATION CONTAINED OR INCORPORATED BY REFERENCE
IN THIS PROXY  STATEMENT/ PROSPECTUS,  HOLDERS OF CLINICOM  COMMON STOCK  SHOULD
CONSIDER CAREFULLY THE FOLLOWING FACTORS IN DETERMINING HOW TO VOTE WITH RESPECT
TO THE MERGER.

EXCHANGE RATIO

    Stockholders should consider that, because the Exchange Ratio is fixed at .4
of a share of HBOC Common Stock for each share of CliniCom Common Stock, holders
of  CliniCom Common Stock will not receive additional consideration in the event
that the value of a share of CliniCom  Common Stock exceeds 40% of that of  HBOC
Common  Stock.  In addition,  although the  Merger  Agreement provides  that the
CliniCom Board may  terminate the  Merger Agreement or  elect not  to close  the
transactions  contemplated thereby in the event the average closing price of the
HBOC Common  Stock is  less  than $50.00  over  certain specified  periods,  the
CliniCom  Board may waive such provisions. See  "The Merger Proposal -- Terms of
the Merger."

ACQUISITIONS AND INTEGRATION

   
    An important element of HBOC's business strategy has been to expand  through
acquisitions.  See  "Business of  HBOC --  Strategy."  HBOC's future  success is
partially  dependent  upon  its   ability  to  effectively  integrate   acquired
businesses  with  HBOC's  operations.  Although HBOC  believes  that  its recent
acquisitions will  be  successful  and that  it  will  be able  to  effect  such
integration,  there can be no assurance that past or future acquisitions will be
successfully  integrated  or  that  any  such  acquisition  will  otherwise   be
successful.  In  addition, the  financial performance  of HBOC  is now  and will
continue to  be subject  to various  risks associated  with the  acquisition  of
businesses,  including the financial effects  associated with the integration of
such businesses. During the fiscal quarter ended June 30, 1995, HBOC recorded  a
$126 million pre-tax charge in connection with its acquisition of HSG from FDC.
    

HEALTHCARE INDUSTRY AND MARKET CHANGES

    The  healthcare  industry is  subject  to changing  political,  economic and
regulatory influences  that  may  affect the  procurement  practices  and  other
operational  aspects of the healthcare industry.  During the past several years,
the healthcare  industry  has  been  subject  to  an  increase  in  governmental
regulation  of,  among other  things,  reimbursement rates  and  certain capital
expenditures. A number of lawmakers have  announced that they intend to  propose
programs  to  reform  the U.S.  healthcare  system. These  programs  may contain
proposals  to   increase   governmental   involvement   in   healthcare,   lower
reimbursement  rates and otherwise  change the operating  environment for HBOC's
customers. Cost containment  measures instituted by  healthcare providers  could
result  in greater selectivity  in the allocation of  capital funds, which could
have an adverse effect on HBOC's ability to sell its products and services. HBOC
cannot predict  with  any certainty  what  effect,  if any,  such  proposals  or
healthcare reforms might have on its business, financial condition or results of
operations.

    In  addition, the  healthcare industry  is currently  undergoing significant
consolidation of healthcare providers  resulting in a  smaller number of  larger
healthcare  delivery enterprises. The changing industry profile produced by this
consolidation could have an adverse  impact on HBOC's margins and  profitability
due to increased competition.

    Certain  clinical applications  of HBOC's computer-assisted  services may be
subject to regulation by the federal Food and Drug Administration (the "FDA") as
medical  devices.  Such  regulation  would  require  the  registration  of   the
applicable manufacturing facility and software/hardware products, application of
detailed  recordkeeping and manufacturing standards, and pre-market notification
to the  FDA  of  HBOC's intent  to  market  the applications  in  question.  The
pre-market  notification procedure could create delays in marketing, and the FDA
could require supplemental filings or object to certain of these applications.

                                       12
<PAGE>
COMPETITION

    The industry in  which HBOC operates  is highly competitive  and subject  to
continual  change in the manner in which  products and services are marketed and
vendors are selected by customers. The primary competitive factors are scope and
quality of products and  service and support  capabilities. Certain current  and
potential competitors have greater resources than HBOC.

TECHNOLOGICAL CHANGE; PROPRIETARY TECHNOLOGY

    Future advances in the healthcare information systems industry could lead to
new  technologies, products or  services that are  competitive with the products
and services offered by HBOC. HBOC's continued success will depend, in part,  on
its  ability to be responsive to technological developments and challenges. Such
technological advances could also lower the  cost of such products and  services
or  otherwise  result  in competitive  pricing  pressures, which  could  have an
adverse effect  on  HBOC.  To  remain competitive  in  the  evolving  healthcare
information  systems marketplace,  HBOC must  develop new  products on  a timely
basis. The failure to develop competitive products or to introduce new  products
on  a  timely basis  could have  an  adverse effect  on HBOC's  future financial
performance.

    HBOC relies on a combination of trade secret, copyright and trademark  laws,
nondisclosure and other contractual provisions and technical measures to protect
its  proprietary rights in  its products. There  can be no  assurance that these
protections will be adequate or  that HBOC's competitors will not  independently
develop  technologies that  are substantially  equivalent or  superior to HBOC's
technology. Although  HBOC  believes that  its  products and  other  proprietary
rights  do not infringe upon the proprietary  rights of third parties, there can
be no assurance that third parties  will not assert infringement claims  against
HBOC in the future.

PRODUCT LIABILITY

    Certain  of  HBOC's products  provide  applications that  relate  to patient
medical histories and  treatment plans.  Although HBOC has  not experienced  any
material  claims to date, any failure of HBOC's products to provide accurate and
timely information could result in claims against HBOC. HBOC maintains insurance
to protect against claims associated with the use of its products, but there can
be no assurance  that its insurance  coverage would adequately  cover any  claim
asserted against HBOC.

POSSIBLE VOLATILITY OF STOCK PRICE

    The  stock market has from time to time experienced extreme price and volume
fluctuations, particularly in the high technology sector, which have often  been
unrelated   to  the   operating  performance   of  particular   companies.  Such
fluctuations and factors such as  announcements of technological innovations  or
new  products by  HBOC or its  competitors or  third parties, as  well as market
conditions in the computer software or hardware industries and healthcare reform
measures, may have  a significant effect  on the market  price of HBOC's  Common
Stock.  Also,  since  HBOC recognizes  revenues  for certain  products  upon the
completion of certain  milestone conditions, delays  in meeting such  conditions
could  result in the shift  of revenue recognition from  one quarter to another.
Any such shift could adversely impact the results of operations for a particular
quarter, which in turn could cause fluctuations in HBOC's stock price.

SHARES ELIGIBLE FOR FUTURE SALE

   
    HBOC has  filed  a registration  statement  in connection  with  a  proposed
underwritten  public offering of up to 4,000,000  shares of HBOC Common Stock by
FDC. Sales, or the availability for sale,  of a substantial number of shares  of
HBOC Common Stock in such offering or otherwise could have a significant adverse
effect on the market price for the HBOC Common Stock.

                                 (In Thousands)

GENERAL
    1.  The foregoing  Pro Forma Combined Income  Statements for the six  months
ended  June 30, 1995, and  the year ended December 31,  1994, give effect to the
acquisition of HSG which  was completed on  June 17, 1995,  and the Merger.  The
foregoing  Pro Forma Combined Balance Sheets as of June 30, 1995, give effect to
the Merger as  if it had  occurred on that  date. No pro  forma adjustments  are
necessary  for the  HSG acquisition  on the  June 30,  1995, Pro  Forma Combined
Balance Sheets since that transaction was completed on June 17, 1995.

    HBOC accounted for the acquisition of  HSG as a purchase. The Merger,  which
is  subject to  certain conditions  including CliniCom  stockholder approval, is
expected to close early in the fourth  quarter of 1995. The transaction will  be
accounted for as a pooling of interests.

    Adjustments  to  the  Pro  Forma  Combined  Income  Statements  include such
adjustments as are  necessary to allocate  the HSG purchase  price based on  the
estimated  fair market value of the  assets acquired and the liabilities assumed
and to  give  effect  to  events  that are  directly  attributable  to  the  HSG
transaction  and the Merger, which  are expected to have  a continuing impact on
HBOC and are  factually supportable. The  adjustments related to  the Pro  Forma
Combined Income Statements assume the transactions were consummated on January 1
of each period presented.

   
    Adjustments   to  the  Pro  Forma   Combined  Balance  Sheets  include  such
adjustments as  are  necessary  to  give effect  to  events  that  are  directly
attributable to the Merger and factually supportable. The adjustments related to
the  Pro Forma Combined Balance Sheets assume the Merger was consummated on June
30, 1995.
    

HSG ACQUISITION
    2.  HSG  revenue and  expense classifications were  historically broken  out
using  different policies than those applied  by HBOC. The adjustments necessary
to reclassify HSG revenue and expenses in accordance with HBOC policies are:

    Historically, HSG  netted certain  costs against  revenue for  presentation,
while HBOC has historically reported revenue as a gross number.

    3.  The following adjustments are necessary to adjust the June 30, 1995, and
December  31,  1994, income  statement impact  of the  asset and  liability fair
market value adjustments, assuming the purchase  of HSG had been consummated  on
January 1 of each period presented:

</TABLE>

    HBOC  recorded the HSG  deferred revenue acquired  at its cost  (the cost to
service remaining commitment). The net profit  which had been deferred has  been
eliminated.

    The  reduction of expense  related to terminated  employees results from the
termination of certain  HSG employees  in order to  eliminate certain  redundant
positions and increase the efficiency of the combined operations.
    4.  HSG was charged an allocated amount for the use of FDC's Data Center. In
1994,  the amount charged was less than  that deemed reasonable by management by
$1,500. The adjusted charge reflects that which  will be charged to HBOC in  the
future. The 1995 charge has been deemed reasonable by management.
    5.  In the second quarter of 1995, HBOC recorded a $125,520 charge primarily
related  to purchased research and development  of HSG. This nonrecurring charge
has  been  eliminated  from  the  June  30,  1995,  Pro  Forma  Combined  Income
Statements.
    6.  The provision for income tax was derived by using the HBOC effective tax
rate of 40%.
    7.   The weighted average shares outstanding  have been adjusted for the HSG
acquisition to give  effect to the  additional 4 million  shares of HBOC  Common
Stock outstanding, assuming the transaction had been consummated on January 1 of
each period presented and to give effect to the dilutive effect of stock options
outstanding at June 30, 1995, assuming that HBOC had net income.

THE MERGER

    8.   Beginning in 1988,  HBOC and CliniCom were  parties to various informal
cooperative   marketing   arrangements.   Accordingly,   certain    intercompany
transactions and balances are included in the historical financial statements of
HBOC   and  CliniCom.  The  adjustments   necessary  to  eliminate  intercompany
transactions assuming the pooling of interests had been consummated on January 1
of each period presented are:

                                  THE MEETING

   
    The enclosed proxy is solicited by the CliniCom Board for use at the Meeting
to be  held at  The Courtyard  by  Marriott, 4710  Pearl East  Circle,  Boulder,
Colorado  80301 on Saturday,  September 30, 1995 at  10:00 a.m. (Mountain Time).
Holders of record of CliniCom Common Stock  on the Record Date will be  entitled
to  vote  at  the Meeting  and  any  adjournment thereof.  On  the  Record Date,
8,663,359 shares of CliniCom Common Stock were outstanding and entitled to vote.
Each of such  shares is entitled  to one vote  on each matter  presented at  the
Meeting.
    

    The  presence at  the Meeting, in  person or by  proxy, of the  holders of a
majority  of  the  issued  and  outstanding  shares  of  CliniCom  Common  Stock
constitutes  a quorum for the transaction of business. If a proxy is returned by
a broker or other stockholder who does not have authority to vote, does not give
authority to a proxy to vote, or  withholds authority to vote as to any  shares,
such  shares  will  be  considered  present  at  the  Meeting  for  purposes  of
determining a quorum. If a quorum is not present or represented at the  Meeting,
the  stockholders entitled to  vote, present in person  or represented by proxy,
have the power to adjourn  the Meeting from time  to time, without notice  other
than  an announcement at the Meeting, until  a quorum is present or represented.
CliniCom will issue a press release  if the Meeting is adjourned, informing  the
stockholders  of the time and place where the Meeting will be reconvened. At any
such reconvened  Meeting  at which  a  quorum  is present  or  represented,  any
business  may be transacted  that might have  been transacted at  the Meeting as
originally described in the notice of the Meeting.

    In order to be  approved, the Merger proposal  must receive the  affirmative
vote  of holders of a majority of  the issued and outstanding shares of CliniCom
Common Stock. Shares of CliniCom Common Stock not represented at the Meeting  or
abstaining  on the proposal to  approve the Merger Agreement  will thus have the
effect of a negative vote.

    Any stockholder giving a proxy has the power to revoke it at any time before
it is  voted by  filing  with the  Secretary of  CliniCom  a written  notice  of
revocation  or duly  executed proxy  bearing a later  date, or  by attending the
Meeting and voting  in person. Each  properly executed unrevoked  proxy will  be
voted  as indicated.  Where specific instructions  are not  indicated, the proxy
will be voted FOR the Merger.

    The cost of soliciting proxies will  be borne by CliniCom. Arrangements  may
be  made with  brokerage houses, custodians,  nominees and  other fiduciaries to
send proxy materials to the beneficial owners of CliniCom Common Stock. CliniCom
will reimburse them for their reasonable out-of-pocket expenses. In addition  to
solicitation  by mail, directors,  officers and employees  of CliniCom, who will
receive no  compensation for  their services  other than  regular salaries,  may
solicit proxies by mail, telephone and electronic transmission and personally.

                              THE MERGER PROPOSAL

BACKGROUND OF THE MERGER

   
    Beginning  in  1988,  CliniCom and  HBOC  were parties  to  various informal
cooperative marketing arrangements. In December 1993, HBOC and CliniCom  entered
into a three-year Software License and Distribution Agreement (together with the
related  agreements dated  as of  such date,  the "HBOC  Agreement") pursuant to
which HBOC was granted a non-exclusive, non-transferable license to use CliniCom
software as described below under "Business of CliniCom -- HBOC Agreement." As a
result of  that long  standing relationship,  CliniCom and  HBOC were  generally
familiar with each other's business and operations.
    
   
    In  June 1994, HBOC reviewed its product  plans for the next 24-month period
and determined that its internal development of a point-of-care nursing solution
with functionality similar to that of the CliniCom product would not be complete
prior to  December 31,  1996, the  date  of expiration  of the  HBOC  Agreement.
Development  of  such  a  product  was  projected  to  require  significant HBOC
resources and expenditures. In addition, HBOC believed it could be disadvantaged
in the marketplace because of  potential confusion over HBOC's clinical  product
direction  in the event it introduced an internally developed product to replace
the product it was offering jointly with CliniCom. As a result of HBOC's review,
HBOC determined that the acquisition of CliniCom would be a solution that should
be pursued.
    
    CliniCom's management  and  Board  of  Directors  has  regularly  considered
CliniCom's  position in the healthcare  information systems industry. Over time,
the CliniCom Board concluded that  CliniCom's long-term strategy must be  either
to  become an integrated system provider or to form strategic alliances with one
or more such providers for  which the CliniCom system would  become a part of  a
larger  integrated  system. See  "--  Reasons of  CliniCom  for Engaging  in the
Merger." In considering the long-term  strategy of CliniCom, the CliniCom  Board
evaluated  the  financial  requirements  necessary  for  CliniCom  to  become an
integrated system provider and  compared the risks and  opportunities of such  a
strategy  with  a strategy  of  forming an  alliance  with an  integrated system
provider.

    On November  9,  1994, Charles  W.  McCall, President  and  Chief  Executive
Officer  of HBOC,  and Jay  P. Gilbertson, Vice  President --  Finance and Chief
Financial Officer of HBOC, met in New Orleans with William H. Brehm, Chairman of
the Board and Chief  Executive Officer of CliniCom,  Catherine K. Milburn,  Vice
President of Finance and Administration and Chief Financial Officer of CliniCom,
and  a representative of Punk, Ziegel and Knoell ("Punk, Ziegel"), an investment
banking firm on  retainer with HBOC,  to discuss  a possible merger  of the  two
companies.

    On  November 10, 1994, HBOC  forwarded to CliniCom a  draft letter of intent
which contemplated the merger of CliniCom with HBOC in which the stockholders of
CliniCom would  receive  shares of  HBOC  with an  implied  value per  share  of
CliniCom  Common  Stock  of  approximately $15.00,  subject  to  certain limited
adjustments tied to fluctuations  in the market price  of HBOC Common Stock.  On
November 10, 1994, the closing price of the CliniCom Common Stock was $11.75 per
share.  The  draft  letter of  intent  included  a requirement  of  a  "no shop"
agreement from CliniCom.

    The draft letter of intent was provided to the CliniCom Board, which met  on
November  18,  1994 to  consider the  proposed  transaction. The  CliniCom Board
concluded that the price proposed in the draft letter of intent was  inadequate,
particularly  in view of the  fact that the market  price of the CliniCom Common
Stock had been as high as $20.75 per share within the preceding two months.  The
CliniCom  Board believed that the decline in the market price of CliniCom Common
Stock to  the  level  prevailing  in November  1994,  which  occurred  following
CliniCom's  announcement  of  results of  its  operations for  the  third fiscal
quarter, was unwarranted  given CliniCom's long-term  outlook. Accordingly,  the
CliniCom  Board authorized  a counterproposal to  HBOC and on  November 22, 1994
CliniCom forwarded a proposed redraft of a letter of intent which contemplated a
merger with an

                                       25
<PAGE>
implied value of approximately $18.50 for  each share of CliniCom Common  Stock,
again  with  certain  limited adjustments.  CliniCom  offered to  allow  HBOC an
opportunity to conduct due diligence  which CliniCom believed would support  its
pricing response.

    On   November  28,  1994,  HBOC   responded  to  CliniCom's  counterproposal
reoffering the terms of  HBOC's original proposal  as to pricing,  as well as  a
number  of other issues, and advising CliniCom that HBOC's offer would terminate
on the following day. On  November 29, 1994, the  offer expired and the  parties
ceased negotiations.

   
    In December 1994, pursuant to authorization by the CliniCom Board granted at
a  meeting on December 1, 1994, CliniCom engaged Volpe, Welty & Company ("Volpe,
Welty"), an investment  banking firm,  as its  financial advisor  to advise  the
CliniCom  Board concerning financial  alternatives for CliniCom  and to identify
and conduct  negotiations with  possible  candidates to  acquire or  merge  with
CliniCom.  On January 4, 1995, a representative of Volpe, Welty met with Messrs.
McCall and  Gilbertson  to  discuss  the  possibility  of  proceeding  with  the
contemplated  merger at an implied value of  $18.50 per share of CliniCom Common
Stock. The HBOC representatives reiterated that HBOC was unwilling to proceed at
an implied value of $18.50 per share. However, due to increases in the price  of
HBOC  Common Stock and anticipated cost savings  from the combination of the two
entities, the HBOC representatives stated that they would be willing to consider
a transaction with an implied  value of up to $17  per share of CliniCom  Common
Stock.  Later in January 1995  CliniCom advised HBOC that  it had no interest in
proceeding on this basis. CliniCom's  engagement of Volpe, Welty was  terminated
in February 1995.
    

    Shortly thereafter, the CliniCom Board determined that it should be prepared
to  pursue a strategy  of remaining an independent  company, and that additional
capital would be  required to implement  that strategy. In  furtherance of  that
strategy,  CliniCom  filed a  registration  statement on  May  5, 1995  with the
Commission which  contemplated  the sale  by  CliniCom of  1,000,000  shares  of
CliniCom  Common  Stock as  well  as the  sale  of 1,000,000  shares  by certain
existing stockholders. On May  4, 1995, the closing  sale price of the  CliniCom
Common Stock was $18.75 per share.

   
    In late May, Mr. Gilbertson had discussions with Arthur DelVesco, a director
of  CliniCom, and representatives of Punk, Ziegel,  which was then acting as one
of the managing underwriters in CliniCom's proposed public offering,  concerning
CliniCom's  business and the possibility of reviving the discussions relating to
a merger of CliniCom with HBOC. Mr.  DelVesco informed the other members of  the
CliniCom  Board of  these discussions  and conferred  with directors  William H.
Brehm and Marshall D. Miller about formulating a response.
    

   
    On June 1, 1995, the parties agreed to resume negotiation of a merger at  an
exchange  ratio of  .47961 of  a share of  HBOC Common  Stock for  each share of
CliniCom Common Stock. On  June 1, 1995,  the closing price  of the HBOC  Common
Stock  was  $48.375, implying  a value  per  share of  CliniCom Common  Stock of
$23.20.
    

   
    Thereafter, HBOC conducted due diligence with respect to CliniCom. Following
informal discussions  among CliniCom's  directors and  management, the  CliniCom
Board  met on June 14, 1995. At  that meeting, Mr. DelVesco advised the CliniCom
Board that  Mr.  Gilbertson had  informed  him that,  as  a result  of  its  due
diligence  investigation, HBOC had determined that an adjustment to the proposed
exchange ratio was  appropriate. The  CliniCom Board determined  that the  price
adjustment  proposed by Mr. Gilbertson, to an  implied value of $18.00 per share
for the CliniCom  Common Stock,  was unacceptable. However,  the CliniCom  Board
directed  CliniCom's  management to  gather  additional information  relating to
CliniCom, and negotiations were suspended pending an opportunity to discuss that
response with  HBOC. At  the same  meeting, the  CliniCom Board  authorized  the
engagement  of Dean Witter Reynolds Inc.  ("Dean Witter"), which was then acting
as one of the managing underwriters  in CliniCom's proposed public offering,  to
represent CliniCom in connection with the negotiation of a proposed transaction,
including the rendering of a fairness opinion to the CliniCom Board.
    

                                       26
<PAGE>
    During  the week of June 26, a  number of conversations took place among the
principals and representatives of HBOC and CliniCom, including a meeting at HBOC
on June 28, 1995,  attended by representatives of  CliniCom, HBOC, Punk,  Ziegel
and  Dean  Witter. As  a result  of these  conversations, on  June 30,  1995 Mr.
Gilbertson, Mr. DelVesco and representatives of Punk, Ziegel and Dean Witter met
by telephone and agreed  to explore a  merger on the basis  of a fixed  exchange
ratio  of .4 of a share  of HBOC Common Stock for  each share of CliniCom Common
Stock, but with a right of CliniCom to terminate if the price of the HBOC Common
Stock declined below  $50.00 per  share for  certain periods.  The parties  then
directed  their  respective  representatives to  negotiate  a  definitive merger
agreement. On June  30, 1995  the closing  price of  the HBOC  Common Stock  was
$54.50 making the implied value per share of the CliniCom Common Stock $21.80.

    On  July 10, 1995, the CliniCom Board of Directors met to consider the draft
Merger Agreement  that had  been  negotiated and  to consider  the  transactions
contemplated  thereby. At that  meeting representatives of  Dean Witter reviewed
the proposed financial  terms of  the Merger,  discussed their  analysis of  the
proposed  transaction  and discussed  their opinion  as to  the fairness  of the
proposed exchange ratio  to the  CliniCom stockholders.  Negotiations with  HBOC
continued,  and the CliniCom  Board convened additional meetings  on July 13 and
July 14. At the July 14 meeting Dean Witter presented its written opinion  that,
as of that date, the Exchange Ratio was fair, from a financial point of view, to
the  CliniCom stockholders. See "-- Opinion  of Financial Advisor for CliniCom."
After deliberating about the proposed Merger Agreement, considering, among other
things, the matters discussed below and  the opinion of Dean Witter referred  to
above,  the CliniCom  Board unanimously authorized  the execution  of the Merger
Agreement and adopted resolutions recommending the  Merger as being in the  best
interests of CliniCom and its stockholders.

    On  July 14, 1995, the HBOC Board also approved the terms of the transaction
and authorized the execution of the  Merger Agreement. The Merger Agreement  was
signed by the parties on that date.

OPINION OF FINANCIAL ADVISOR FOR CLINICOM

   
    In  considering  the proposed  Merger and  whether or  not to  recommend the
Merger to CliniCom's stockholders for approval, the CliniCom Board engaged  Dean
Witter  to provide  financial advisory  services, which  included evaluating the
fairness to the  holders of  CliniCom Common Stock,  from a  financial point  of
view, of the Exchange Ratio. On July 10, 1995, in connection with the evaluation
of  the Merger Agreement by the CliniCom  Board, Dean Witter made a presentation
to the  CliniCom Board  with respect  to  the Merger.  In connection  with  this
presentation,  the  CliniCom  Board was  given  written materials  based  on the
proposed merger as it stood on July 10,  1995. At its meeting on July 14,  1995,
the  CliniCom Board received the oral opinion of Dean Witter to the effect that,
as of such  date and based  upon and subject  to certain matters  stated in  its
opinion,  the Exchange Ratio  was fair, from  a financial point  of view, to the
holders of CliniCom Common  Stock. Dean Witter's opinion  as to the fairness  of
the Exchange Ratio takes into account the provision of the Merger Agreement that
provides  that CliniCom is not required to  consummate the Merger if the average
of the per share closing prices on the NASDAQ-NM as reported in THE WALL  STREET
JOURNAL of HBOC Common Stock for the ten (10) consecutive trading days ending on
the  second trading day prior to the Closing  Date is less than $50.00. The oral
opinion of Dean Witter was subsequently confirmed in writing as of July 14, 1995
and was substantially identical  to their opinion dated  the date of this  Proxy
Statement/Prospectus,  the  full  text  of  which  is  attached  to  this  Proxy
Statement/Prospectus as  Appendix B  and is  incorporated by  reference  herein.
Holders  of shares of CliniCom Common Stock are urged to read the opinion in its
entirety for a  description of the  factors considered and  assumptions made  by
Dean Witter in rendering its opinion.
    

    Dean  Witter was not requested to, and  did not, make any recommendations to
the CliniCom Board as to the form or amount of the consideration to be  received
by  the holders  of shares  of CliniCom  Common Stock  in the  Merger, which was
determined through arm's length negotiations  among the parties. In arriving  at
its  opinion, Dean  Witter did  not ascribe  a specific  range of  fair value to
CliniCom, but made its determinations as  to the fairness of the Exchange  Ratio
on the basis of the financial and comparative analysis described below.

                                       27
<PAGE>
    Dean  Witter's opinion is directed  to the CliniCom Board  only and does not
constitute a recommendation to  any holders of CliniCom  Common Stock as to  how
such  holders should vote on the Merger at the Meeting. In addition, Dean Witter
was not  requested  to opine  as  to, and  its  opinion does  not  address,  the
underlying business decision of the CliniCom Board to proceed with or effect the
Merger.

   
    In  arriving at its  opinion, Dean Witter, among  other things, (i) reviewed
the Merger Agreement; (ii) reviewed the Annual Reports on Form 10-K and  related
publicly  available financial information of CliniCom  for the three most recent
fiscal years ended  December 31,  1994, the  final prospectus,  dated April  20,
1992,  for  CliniCom's initial  public offering  of  CliniCom Common  Stock, the
Quarterly Report on Form 10-Q for the period ended June 30, 1995, and CliniCom's
definitive proxy statement on  Schedule 14A, dated May  3, 1995; (iii)  reviewed
the  Annual  Reports  on  Form 10-K  and  related  publicly  available financial
information of HBOC for  the three most recent  fiscal years ended December  31,
1994,  the Quarterly Report on Form 10-Q for the period ended June 30, 1995, and
HBOC's definitive proxy  statement on Schedule  14A, dated April  3, 1995;  (iv)
reviewed  certain other  information, including  publicly available information,
relating to the business, earnings, cash flow, assets and prospects of  CliniCom
and  HBOC, respectively; (v)  reviewed an income  statement forecast of CliniCom
for the remaining portion of the 1995  fiscal year and for the fiscal year  1996
as  furnished to Dean Witter  by CliniCom; reviewed balance  sheet and cash flow
forecasts of CliniCom for the remaining portion of the 1995 fiscal year and  for
the  fiscal year 1996 as prepared on  the basis of information furnished to Dean
Witter by CliniCom;  (vi) reviewed income  statement forecasts of  HBOC for  the
remaining  portion  of the  1995 fiscal  year and  for the  fiscal year  1996 as
furnished to Dean Witter  by HBOC; (vii) conducted  discussions with members  of
senior  management of CliniCom  and HBOC, respectively,  concerning the past and
current business,  operations, assets,  present financial  condition and  future
prospects  of CliniCom  and HBOC,  respectively; (viii)  reviewed the historical
reported market prices and  trading activity for the  CliniCom Common Stock  and
the  HBOC Common Stock;  (ix) compared certain  financial information, operating
statistics and market  trading information relating  to CliniCom with  published
financial  information,  operating  statistics  and  market  trading information
relating to selected public companies that  Dean Witter deemed to be  reasonably
similar   to  CliniCom;   compared  certain   financial  information,  operating
statistics and  market  trading  information relating  to  HBOC  with  published
financial  information,  operating  statistics  and  market  trading information
relating to selected public companies that  Dean Witter deemed to be  reasonably
similar  to HBOC; (x) compared  the proposed financial terms  of the Merger with
the financial terms, to the extent publicly available, of selected other  recent
acquisitions  that Dean  Witter deemed  to be  relevant; and  (xi) reviewed such
other financial studies and analyses and performed such other investigations and
took into account such other matters as Dean Witter deemed necessary.
    

   
    In preparing its opinion, Dean Witter  assumed and relied upon the  accuracy
and  completeness  of all  financial  and other  information  supplied to  it by
CliniCom and HBOC  or that  was publicly  available, respectively,  and did  not
independently  verify such information.  Dean Witter also  assumed that the HBOC
Agreement has not been materially modified  or amended since the dates  thereof.
Dean  Witter  has  also  relied  upon  the  managements  of  CliniCom  and HBOC,
respectively, as  to  the reasonableness  and  achieveability of  the  financial
forecasts  of CliniCom and HBOC (and the assumptions and bases thereof) provided
to it or prepared on the basis  of information and assumptions furnished to  it,
and,  with the  CliniCom Board's consent,  has assumed that  such forecasts have
been reasonably prepared on  the basis reflecting  the best currently  available
estimates  and  judgments  of  such  respective  managements  as  to  the future
operating performance  of CliniCom  and  HBOC, respectively.  Furthermore,  Dean
Witter  assumed  that  the Merger  would  qualify  (i) for  pooling  of interest
accounting treatment and (ii) as a reorganization within the meaning of  Section
368(a)  of the  Internal Revenue  Code of  1986, as  amended (the  "Code"). Dean
Witter was not requested to make, and  Dean Witter has not made, an  independent
appraisal  or  evaluation of  assets, properties,  facilities or  liabilities of
CliniCom or HBOC and it was not furnished with any such appraisal or evaluation.
    

                                       28
<PAGE>
    Dean   Witter's  opinion  was  necessarily   based  upon  prevailing  market
conditions (including market prices  for CliniCom Common  Stock and HBOC  Common
Stock)  and  other circumstances  and conditions  as they  existed and  could be
evaluated as of the  date of the  opinion, and did  not represent Dean  Witter's
opinion  as to  what the actual  value of  CliniCom Common Stock  or HBOC Common
Stock would be after the date thereof.

    In connection with advising  the CliniCom Board of  its opinion on July  14,
1995  and in preparing its written and oral presentations to the CliniCom Board,
Dean Witter performed a variety of financial and comparative analyses  including
those  described below. The  preparation of a  fairness opinion involves various
determinations as  to the  most appropriate  and relevant  methods of  financial
analysis  and the application  of those methods  to the particular circumstances
and,  therefore,  such  an  opinion  is  not  readily  susceptible  to   summary
description.  Furthermore, in arriving at its  fairness opinion, Dean Witter did
not attribute  any  particular  weight  to any  particular  analysis  or  factor
considered  by it, but rather made  qualitative judgments as to the significance
and relevance of  each analysis  and factor. Accordingly,  Dean Witter  believes
that its analysis must be considered as a whole and that considering any portion
of  such analysis and  the factors considered,  without considering all analyses
and factors,  could  create a  misleading  or  incomplete view  of  the  process
underlying the opinion.

    In  its  analysis, Dean  Witter made  numerous  assumptions with  respect to
industry  performance,  general  business  and  economic  conditions  and  other
matters,  many  of  which are  beyond  the  control of  CliniCom  and  HBOC. Any
estimates contained in this  analysis are not  necessarily indicative of  actual
values  or predictive  of future results  or values, which  may be significantly
more or less favorable than as set forth therein. In addition, analyses relating
to the value of  businesses do not  purport to be appraisals  or to reflect  the
prices at which businesses actually may be sold.

    Unless  otherwise  indicated, all  references  to the  value  of a  share of
CliniCom Common Stock in the following description of the analyses conducted  by
Dean  Witter assume the  exercise of all  options for shares  of CliniCom Common
Stock.

    ANALYSIS OF SELECTED  PUBLICLY TRADED COMPANIES.   Using publicly  available
information,   Dean  Witter  compared   selected  quantitative  data  (including
revenues,  earnings  before  interest,  taxes,  depreciation  and   amortization
("EBITDA"),  earnings before interest and taxes ("EBIT"), and earnings per share
("EPS")), and qualitative information (including competitive position,  customer
base,  management, stage of technological  development, stage of capital funding
and intercompany relationships) regarding CliniCom with similar data of selected
publicly traded health care information systems ("HCIS") companies competing  in
the  hospital applications business  segment ("Hospital Applications Companies")
and other HCIS companies engaged in  businesses considered by Dean Witter to  be
comparable  to those of CliniCom  (including the Hospital Application Companies,
the "HCIS Universe"). Specifically,  for CliniCom, Dean  Witter included in  its
review   of  Hospital  Applications  Companies,  Cerner  Corporation  and  Pyxis
Corporation, and in the HCIS Universe, a group of 13 additional HCIS  companies,
consisting of C.I.S. Technologies, Inc., CyCare Systems, Inc., GMIS, Inc., HBOC,
HCIA,  Inc.,  Health  Management  Systems,  Inc.,  Medaphis  Corporation,  Medic
Computer Systems,  Inc., Medicus  Systems Corporation,  Phamis, Inc.,  Physician
Computer  Network,  Inc.,  Quality  Systems,  Inc.  and  Shared  Medical Systems
Corporation.

    Of these companies, the analysis  relied primarily on trading multiples  and
qualitative factors associated with the Hospital Applications Companies, as they
were  deemed by Dean Witter to be  the most comparable companies to CliniCom due
to their similar business focus. Such  data and ratios included a comparison  of
CliniCom  with  the  Hospital  Applications Companies  assuming  a  valuation of
CliniCom Common  Stock of  $23.40 per  share (the  price per  share of  CliniCom
Common  Stock on July  14, 1995 after  giving effect to  the Exchange Ratio), in
relation to latest 12  months ("LTM") revenues, LTM  EBITDA, LTM EBIT, LTM  EPS,
projected  1995 calendar  year EPS  and projected  1996 calendar  year EPS (such
projected EPS figures for the HCIS Universe, other than CliniCom and HBOC, being
based upon the means of publicly  available estimates made by research  analysts
and  provided by  Dean Witter  research analysts  or as  reported by  First Call
Corporation, an earnings

                                       29
<PAGE>
estimate reporting service provided by Thompson Financial Services Company). The
valuation multiples for CliniCom based on  a price of $23.40 per share  compares
with  the range (and  mean) of the  Hospital Applications Companies  of: for LTM
revenues, 5.6  times for  CliniCom versus  6.1  to 5.6  times for  the  Hospital
Applications Companies (5.9 times mean); for LTM EBITDA, 29.6 times for CliniCom
versus  19.7 to 15.6  times for the Hospital  Applications Companies (17.7 times
mean); for LTM EBIT, 37.3 times for  CliniCom versus 25.3 to 16.3 times for  the
Hospital  Applications Companies (20.8 times mean);  for LTM EPS, 52.5 times for
CliniCom versus 45.7 to 27.1 times for the Hospital Applications Companies (36.4
times mean);  for calendar  year 1995  projected EPS,  39.8 times  for  CliniCom
versus  38.6 to 23.2  times for the Hospital  Applications Companies (30.9 times
mean); and for calendar year 1996 projected EPS, 29.1 times for CliniCom  versus
31.5 to 18.2 for the Hospital Applications Companies (24.9 times mean).

    Although  Dean Witter relied primarily  on trading multiples and qualitative
factors associated with Hospital Applications Companies, Dean Witter also relied
on trading multiples and  qualitative factors associated  with all companies  in
the  HCIS Universe. Such data and ratios  included a comparison of CliniCom with
all the companies in the HCIS Universe in relation to the same trading multiples
as set forth above, assuming a valuation of CliniCom Common Stock of $23.40  per
share. The valuation multiples for CliniCom based on a price of $23.40 per share
compares  with the range (and  mean) of the HCIS  Universe of: for LTM revenues,
5.6 times for CliniCom versus 9.4 to 1.5 times for the HCIS Universe (4.5  times
mean);  for LTM EBITDA, 29.6 times for CliniCom versus 33.0 to 8.4 times for the
HCIS Universe (19.9 times  mean); for LTM EBIT,  37.3 times for CliniCom  versus
40.7  to 10.0 times for  the HCIS Universe (26.9 times  mean); for LTM EPS, 52.5
times for CliniCom versus 61.6 to 14.3  times for the HCIS Universe (38.4  times
mean); for calendar year 1995 projected EPS, 39.8 times for CliniCom versus 54.8
to  11.1 times for  the HCIS Universe  (33.2 times mean);  and for calendar year
1996 projected EPS,  29.1 times for  CliniCom versus  36.8 to 8.7  for the  HCIS
Universe (24.4 times mean).

   
    Because  of the  inherent differences  between the  products, operations and
other characteristics of CliniCom and  selected public companies comprising  the
HCIS  Universe, Dean  Witter believes  that an  appropriate use  of a comparable
company analysis  also  involves qualitative  judgments  concerning  differences
between the financial and operating characteristics of CliniCom and the selected
public  companies, which affects  the public trading values  of CliniCom and the
selected companies, which judgments are reflected in Dean Witter's opinion.
    

    COMPARABLE TRANSACTION ANALYSIS.   Dean  Witter reviewed  with the  CliniCom
Board  the  prices  and  multiples  paid  for  other  HCIS  companies  in recent
acquisitions or mergers that Dean Witter  deemed comparable to the Merger.  Dean
Witter  specifically  reviewed the  following public  transactions (the  date of
announcement of the transaction is set forth next to each such transaction): The
Thompson Corporation/The  MEDSTAT,  Group  Inc. (November  11,  1994),  Medaphis
Corporation/AdvaCare,  Inc. (July 21, 1994) and HBOC/Serving Software, Inc. (May
13, 1994). In addition, Dean Witter  examined 25 private market transactions  in
the  HCIS industry during the  time period beginning in  1991 through July 1995.
Such analysis  indicates  the average  of  the  purchase prices  in  the  public
transactions  on a basis of a multiple  of revenue, EBITDA, EBIT, net income and
tangible book value was 3.5  times, 17.4 times, 30.9  times, 50.0 times and  9.2
times,  respectively,  with  respect  to  the  public  market  transactions, (as
compared to CliniCom multiples of 5.6 times, 29.6 times, 37.3 times, 52.5  times
and  7.7 times,  respectively, and assuming  a valuation of  the CliniCom Common
Stock of $23.40 per share) and on a basis of a multiple of revenue and EBIT  for
the  private market  transactions, 2.8 times,  and 15.2  times, respectively (as
compared to  CliniCom  multiples of  5.6  times and  37.3  times,  respectively,
assuming a valuation of the CliniCom Common Stock of $23.40 per share).

    No  company or  transaction used  as a comparison  in the  above analysis is
identical to CliniCom or the Merger. Accordingly, analysis of the results of the
foregoing is not  mathematical; rather  it involves  complex considerations  and
judgments  concerning the differences in financial and operating characteristics
and terms and  structure of  CliniCom and  the Merger,  respectively, and  other
factors  that could affect the  public trading values of  the companies to which
CliniCom is being compared.

                                       30

    INTERCOMPANY RELATIONSHIPS.  In its presentation to the CliniCom Board, Dean
Witter noted the extent to which,  particularly during recent fiscal periods,  a
substantial  and  increasing  percentage  of  CliniCom's  revenues  were derived
pursuant to  the  HBOC Agreement.  Dean  Witter  noted that  the  percentage  of
CliniCom  revenues attributable to HBOC pursuant to the HBOC Agreement increased
from 29.2% of total revenues during the 1994 fiscal year to over 56.0% of  total
revenues during the quarter ended March 31, 1995.

   
    STOCK  TRADING HISTORY.   Dean  Witter examined  the history  of the trading
prices and volume of CliniCom  Common Stock, the relationship between  movements
in  the prices of CliniCom Common Stock  and movements in certain stock indices,
and a relationship between movements in the prices of CliniCom Common Stock  and
press  announcements and other public disclosures.  From January 2, 1995 through
July 14, 1995 (the  last trading date prior  to CliniCom's announcement that  it
had  entered into the Merger Agreement),  the highest closing price for CliniCom
Common Stock was $21.00, on April 11  and 12, 1995. During the same period,  the
lowest  closing price for CliniCom Common Stock was $11 1/2, on January 2, 1995.
In the month prior to the announcement of the execution of the Merger Agreement,
CliniCom Common Stock  traded in the  $15 3/4  to $18 5/8  range. Following  the
announcement of the execution of the Merger Agreement on July 17, 1995, CliniCom
Common Stock traded as high as $22.00 during such trading day.
    

    Dean Witter reviewed and analyzed performance of the per share market prices
and  trading volume  of CliniCom  Common Stock  and HBOC  Common Stock  over the
period from July  7, 1994 through  July 6, 1995  (the "Comparison Period")  both
separately and in relation to each other and/or certain performance indices (Dow
Jones  Industrial  Average and  Nasdaq  Composite Index  (the  "Indices")). Dean
Witter noted that  during the  term of  the Comparison  Period, CliniCom  Common
Stock  had not performed consistently as well  as the Indices. Dean Witter noted
that this performance could be attributable  in part to the relative  volatility
of CliniCom's earnings stream and increasing percentage of revenues attributable
to  CliniCom's relationship with HBOC. Conversely,  for a substantial portion of
the Comparison Period, HBOC Common Stock  performance was well in excess of  the
Indices.

    Dean  Witter also  noted that  the trading volume  of HBOC  Common Stock was
substantially greater  than  that  of  CliniCom  Common  Stock  and,  therefore,
ownership  of HBOC Common Stock would  provide greater liquidity for the holders
of CliniCom  Common Stock.  Dean Witter  noted that  the recent  performance  of
CliniCom  Common Stock when  compared with the Indices  and recent and long-term
performance of HBOC  Common Stock at  levels at or  above the Indices  described
above, were all factors to be considered by the CliniCom Board in evaluating the
Merger.

    CONTRIBUTION  ANALYSIS.  Dean Witter calculated  the contribution of each of
CliniCom and HBOC  to the pro  forma combined entity  with respect to  revenues,
EBIT  and net income. The foregoing contributions were examined for the one year
period ended  December 31,  1994,  and for  the  projected fiscal  years  ending
December  31, 1995 and December  31, 1996. The analysis  was based on CliniCom's
projections for the foregoing  periods and produced  a relative contribution  of
CliniCom  to the pro  forma combined entity  (unadjusted for intercompany sales)
for the foregoing periods, respectively, of (i) 9.8%, 9.1% and 9.7% of revenues,
(ii) 9.7%, 8.8% and 8.5% of EBIT and  (iii) 11.6%, 9.7% and 9.2% of net  income.
Based  on the closing prices of CliniCom Common Stock and HBOC Common Stock, the
holders of CliniCom Common Stock would  have approximately 9.6% pro forma  fully
diluted equity ownership of the pro forma combined entity.

    Dean  Witter concluded that CliniCom's  pro forma equity ownership generally
equaled or  exceeded such  contribution to  the pro  forma combined  entity  and
therefore concluded that the results of such analysis support its opinions. Dean
Witter  did not compute  implied exchange ratios  from the contribution analysis
but prepared  such analysis  only for  informational purposes  for the  CliniCom
Board.

    DISCOUNTED  CASH FLOW ANALYSIS.  Using a discounted cash flow analysis, Dean
Witter estimated the  present value  of the future  cash flow  that CliniCom  is
projected to produce over a one and three

                                       31
<PAGE>
quarter  year  period  from  April 1995  through  December  1996,  under various
assumptions,  if  CliniCom   were  to  perform   in  accordance  with   CliniCom
management's  forecasts. Dean Witter  estimated the terminal  values of CliniCom
Common Stock at the end of the one and three quarter year period and  discounted
such  terminal values back  to present values at  different discount rates based
upon a consideration of a number of factors, including cost of capital, required
rates of  return to  investors  and risks  attributable  to uncertainty  of  the
projected  cash  flow. The  foregoing analysis  resulted in  a range  of present
values per share  for CliniCom Common  Stock of $17.28  to $24.34. As  indicated
below, this analysis is not necessarily indicative of actual values or of actual
future  results  and  does  not  purport to  reflect  the  prices  at  which any
securities may trade at the present time or at any time in the future.

   
    In addition, Dean Witter applied the discounted cash flow analysis, based on
available information, to the HBOC cash flow to arrive at an estimated range  of
present  values per  share for  HBOC Common  Stock. After  giving effect  to the
Exchange Ratio,  Dean  Witter compared  the  relative values  of  the  resulting
analysis.  Dean  Witter  noted  that  during  the  period  for  which management
projections were available,  the relative  value of  the HBOC  Common Stock  was
higher than that of the CliniCom Common Stock.
    

    Dean  Witter is an  internationally recognized investment  banking firm with
substantial experience in  transactions similar  to the Merger  and is  familiar
with  CliniCom  and  HBOC  and  their  respective  businesses.  As  part  of its
investment banking business, Dean Witter  is regularly engaged in the  valuation
of  businesses and their securities in connection with mergers and acquisitions,
negotiated underwritings, private placements, secondary distributions of  listed
and  unlisted securities, and  valuations for corporate  and other purposes. The
CliniCom Board selected  Dean Witter  because of its  expertise, reputation  and
familiarity with the HCIS industry.

    As  compensation for its financial advisory  services in connection with the
Merger,  Dean  Witter  will  receive  a  fee  of  $690,000  from  CliniCom  upon
consummation  of the Merger. Whether or  not the Merger is consummated, CliniCom
has agreed to  reimburse Dean Witter  for reasonable expenses  incurred by  Dean
Witter, including fees and disbursements of counsel, up to $25,000. CliniCom has
also agreed to indemnify Dean Witter and certain related persons against certain
liabilities  to  which  Dean  Witter  may become  subject  as  a  result  of its
engagement, including liabilities under the federal securities laws.

    Dean Witter  had  recently been  selected  by  CliniCom to  lead  manage  an
offering  of CliniCom Common Stock, in respect of which a Registration Statement
on Form S-3 had been previously filed with the SEC, but which was not completed.
Dean Witter has received  no fees in  respect of such  proposed offering or  any
other services for CliniCom prior to the Merger. Dean Witter regularly publishes
research  reports regarding the HCIS industry and the business and securities of
publicly owned companies in that industry and has previously published  research
reports  regarding CliniCom  and HBOC. In  the ordinary course  of its business,
Dean Witter  trades CliniCom  Common Stock  and HBOC  Common Stock  for its  own
account  and for the account of its customers and may at any time hold a long or
short position in such securities.

    Dean Witter does not intend to undertake any review or analysis with respect
to the Merger after the date of this Proxy Statement/Prospectus.

REASONS OF CLINICOM FOR ENGAGING IN THE MERGER

    The CliniCom Board has unanimously approved the proposed Merger pursuant  to
the  Merger  Agreement  as being  in  the  best interests  of  CliniCom  and its
stockholders. In reaching their decision the directors considered the  following
factors  and recommend that these factors also be considered by the stockholders
in voting on the Merger Agreement:

    1.  The healthcare  information systems industry  has been characterized  by
rapid  change and development over the last several years. One characteristic of
this change has been the movement toward integrated information systems that are
available from  a single  provider  to meet  the  needs of  regional  healthcare
networks.  After evaluation of CliniCom's position in the industry, the CliniCom

                                       32
<PAGE>
Board had concluded  that its  long-term strategy must  be either  to become  an
integrated  system provider or to form strategic alliances with one or more such
providers for  which  the  CliniCom system  would  become  a part  of  a  larger
integrated system.

   
    To  become an  integrated system provider  would require  that CliniCom both
substantially expand its development of  the CliniCom systems and seek,  through
acquisitions  or strategic alliances  with other companies,  to obtain access to
those portions of the integrated system that would be unfeasible for CliniCom to
develop independently.  The CliniCom  Board  authorized CliniCom  management  to
explore  and evaluate acquisition candidates and strategic alliances which might
facilitate CliniCom's expansion to become an integrated system provider. Several
possible candidates  for  pursuing that  strategy  were explored  by  CliniCom's
management,  and one  acquisition, of  KSH Systems,  Inc., was  completed in the
summer of 1994.  It was  recognized, however,  that substantial  funds would  be
required  to successfully pursue such a strategy,  and in anticipation of such a
need, in May 1995, CliniCom filed  a registration statement with the  Commission
in  preparation for  a public  offering of CliniCom  Common Stock  to raise such
funds.
    

    While authorizing the pursuit of a growth strategy, the CliniCom Board  also
remained  open  to the  possibility  that it  would  be better  for  CliniCom to
accomplish a strategic partnership  through a merger  with another company.  The
proposal  from HBOC appeared  to the CliniCom  Board to offer  an opportunity to
realize value for the stockholders with  less risk than the course of  expanding
CliniCom into an integrated system provider.

   
    2.   The  existing relationship  between HBOC  and CliniCom  provides a firm
foundation for  combining  CliniCom's products  and  business into  HBOC.  After
entering  into  the HBOC  Agreement in  December 1993,  29% of  CliniCom's total
revenues in  1994  were received  through  HBOC,  and revenues  from  HBOC  have
represented  more than 50% of CliniCom's revenues in 1995. The importance of the
CliniCom clinical  information system  as a  part of  HBOC's information  system
offerings,  as well as the importance of the HBOC relationship to the successful
marketing of CliniCom's systems, has therefore been established. Moreover,  HBOC
has  substantially greater resources to support the continued development of the
CliniCom system, and its larger customer base and marketing organization  offers
opportunities  for wider distribution  of the CliniCom  system. The inclusion of
the CliniCom system  in the  HBOC system  will permit  CliniCom stockholders  to
realize  economic benefits from  CliniCom's product development  efforts to date
through continued participation as stockholders  of HBOC. For these reasons  the
CliniCom Board believes that the Merger with HBOC is strategically appropriate.
    

    3.   The CliniCom Board considered that  the prospects of HBOC are likely to
be enhanced as  a result  of the  Merger because  of the  contribution that  the
CliniCom  systems  offer  to  the  HBOC  integrated  information  systems,  thus
enhancing HBOC's position  as a leader  in offering integrated  systems with  an
additional key component owned internally by HBOC. The cost savings of operating
the  CliniCom business  as a  part of HBOC  as distinguished  from a stand-alone
business  was  believed  to  enhance  HBOC's  prospects  for  benefitting   from
integration of the CliniCom products into the HBOC systems.

   
    4.   The opinion of Dean Witter that the transaction is fair to the CliniCom
stockholders from a  financial point of  view, and the  analysis of Dean  Witter
which led to that conclusion, were considered by the directors.
    

   
    5.   The CliniCom Board recognized that the implied value of the HBOC Common
Stock, which  will be  received  by the  CliniCom  stockholders in  the  Merger,
represents a premium over the market prices of the CliniCom Common Stock at most
times  in  recent  months.  The  Merger  also  offers  CliniCom  stockholders an
opportunity to acquire,  in a  tax-free transaction, shares  in a  significantly
larger  company whose  shares have  increased significantly  in price  in recent
years and have  generally had  less price  volatility than  the CliniCom  Common
Stock.
    

    6.   The CliniCom Board considered financial  and other terms of the Merger,
including (a)  that the  Merger  would generally  be  tax-free to  the  CliniCom
stockholders who will receive HBOC Common

                                       33
<PAGE>
Stock  in the Merger (see "-- Certain  Federal Income Tax Consequences") and (b)
that the Merger will  be subject to approval  by the CliniCom stockholders  and,
while  the Merger Agreement  contains a "no  shop" clause and  a termination fee
provision  (see   "--   Terms   of   the  Merger   --   No   Solicitation"   and
"--  Termination"), the Merger Agreement permits CliniCom to provide information
to or enter into discussions or negotiations with other persons if the  CliniCom
Board  determines that  this is  appropriate in  the exercise  of the Directors'
fiduciary duties. The Merger Agreement  also provides that CliniCom may  decline
to  consummate the Merger or  may terminate the Merger  Agreement if the average
price of the HBOC Common Stock falls below $50.00 per share for certain  periods
prior  to completion of the Merger,  thus permitting the Directors to reconsider
whether the  transaction  is  still  in  the  best  interests  of  the  CliniCom
stockholders  if  a substantial  and sustained  decline in  the market  price of
HBOC's Common Stock occurs prior to consummation of the Merger.

    7.   The  CliniCom  Board  analyzed  the  financial  condition,  results  of
operations  and prospects of HBOC in  evaluating the consideration that would be
received by CliniCom  stockholders in the  Merger. HBOC's history  of growth  in
revenue  and earnings over several years, together with increasing market prices
for the HBOC Common Stock which appears to reflect that growth, were  considered
potentially  beneficial to the CliniCom stockholders  who would receive the HBOC
Common Stock in the Merger.

    8.  In considering the possible exchange of shares of CliniCom Common  Stock
for  shares  of HBOC  Common Stock,  the CliniCom  Board considered  the greater
diversity of  products  offered by  HBOC  than by  CliniCom  and that  HBOC  may
therefore be less vulnerable to adverse business developments than CliniCom on a
stand-alone  basis. As a result, HBOC offers  a prospect of greater stability in
its future operations.

    The foregoing discussion of  the information and  factors considered by  the
CliniCom  Board is not intended to be  exhaustive but is believed to include the
material factors considered by the CliniCom Board. In reaching its determination
to approve  and recommend  the Merger,  the CliniCom  Board did  not assign  any
relative  or specific weights to the  foregoing factors and individual Directors
may have given differing  weights to different factors.  The CliniCom Board  is,
however,  unanimous  in its  recommendation  to CliniCom  stockholders  that the
Merger Agreement be adopted.

REASONS OF HBOC FOR ENGAGING IN THE MERGER

    The HBOC Board believes that  the addition of CliniCom's  multi-disciplinary
clinical  solution (as to  which HBOC currently  has a license  from CliniCom to
offer through 1996) to its product  line will further its business objective  of
providing  healthcare information systems and technology to meet virtually every
need of healthcare enterprises.

    The HBOC  Board  considered  that  the alternative  to  the  acquisition  of
CliniCom  was internal development of a  competitive product which would require
significant resources and expenditures. In  addition, the HBOC Board  recognized
that  it could  be disadvantageous  to market  a new  HBOC developed  product in
competition with the jointly offered product of HBOC and CliniCom.

    The  HBOC  Board  believes  that   the  jointly  offered  CliniCom   product
complements  HBOC's  clinical information  systems  portfolio and  satisfies the
needs of its existing customer base.

TERMS OF THE MERGER

   
    HBOC, HBOC-GA and  CliniCom entered into  the Merger Agreement  dated as  of
July  14, 1995. The following summary of  the terms and conditions of the Merger
Agreement is qualified in  its entirety by  reference to the  full terms of  the
Merger  Agreement  which  is  attached  hereto  as  Appendix  A  and  is  hereby
incorporated by reference herein.
    

    EFFECTIVE TIME OF  THE MERGER.   As  soon as  practicable after  all of  the
conditions  to the Merger have been satisfied  or waived, HBOC and CliniCom will
cause a Certificate of Merger to be filed on behalf of HBOC-GA and CliniCom with
the Secretary of State of  Delaware to make the  Merger effective (the time  the
Merger  becomes effective being referred to herein as the "Effective Time of the
Merger").

                                       34
<PAGE>
   
    EXCHANGE RATIO.   Each share  of CliniCom Common  Stock that  is issued  and
outstanding at the Effective Time of the Merger will be converted into the right
to receive .4 of a share of HBOC Common Stock (the "Exchange Ratio").
    

    FRACTIONAL  SHARES.  No certificates or scrip representing fractional shares
of HBOC Common Stock will  be issued in the Merger  but in lieu thereof, a  cash
payment will be made therefor, without interest, at a pro rata amount based on a
per  share amount equal to the average of  the closing prices of the HBOC Common
Stock on the NASDAQ-NM for the ten  (10) consecutive trading days ending on  the
second  trading day prior to  the date on which  the closing of the transactions
contemplated by the Merger Agreement occurs (the "Closing Date").

    OPTIONS.  Options to purchase shares of CliniCom Common Stock outstanding at
the Effective Time of the Merger shall  be assumed by HBOC, by which  assumption
the optionee shall have the right to purchase the number of shares (rounded down
to the nearest whole share) of HBOC Common Stock into which the number of shares
of  CliniCom  Common  Stock the  optionee  was  entitled to  purchase  under the
existing options would have been converted  pursuant to the Exchange Ratio.  The
aggregate  price for the total number of shares of HBOC Common Stock purchasable
pursuant to an  option shall  be the  aggregate price  at which  the option  was
exercisable  for the total number of shares of CliniCom Common Stock purchasable
thereunder reduced (as necessary for rounding down) to that price that will  buy
the  number of whole shares of HBOC  Common Stock purchasable thereunder and the
purchase price per  share of  HBOC Common Stock  shall be  such aggregate  price
divided  by  the  total  number  of  shares  of  HBOC  Common  Stock purchasable
thereunder. No other terms of the options will be modified.

    EMPLOYEE STOCK PURCHASE PLAN.  Each participant in the CliniCom Incorporated
Employee Stock Purchase Plan (the  "Employee Stock Purchase Plan") will  receive
the  number of  shares of HBOC  Common Stock  into which the  shares of CliniCom
Common Stock issuable to such participant in accordance with the Employee  Stock
Purchase Plan would have been converted and cash in lieu of any fractional share
of  HBOC Common Stock, together  with a cash refund of  any excess of the amount
collected during the purchase  period over the amount  of the purchase price  of
the CliniCom Common Stock that would otherwise be issuable to the participant.

    EXCHANGE  OF  CERTIFICATES.   HBOC has  designated  Trust Company  Bank (the
"Exchange Agent") to act as exchange agent in connection with the Merger. At the
Effective Time of the Merger, HBOC shall  deliver (or cause to be delivered)  to
the  Exchange Agent a sufficient number of  shares of HBOC Common Stock and cash
to make payment for shares of CliniCom  Common Stock converted by reason of  the
Merger. Promptly after the Effective Time of the Merger, the Exchange Agent will
mail  to each  record holder  (as of  the Effective  Time of  the Merger)  of an
outstanding certificate or certificates that immediately prior to the  Effective
Time  of the Merger represented outstanding shares of CliniCom Common Stock (the
"Certificates") a letter of  transmittal and instructions  for use in  effecting
the surrender of the Certificates for exchange and/or payment therefor.

    Upon  surrender to the  Exchange Agent of a  Certificate, together with such
letter of transmittal properly  completed and duly  executed, together with  any
other  required documents, the  holder of such Certificate  shall be entitled to
receive in exchange therefor a certificate representing the number of shares  of
HBOC  Common Stock  equal to  the product  of the  number of  shares of CliniCom
Common Stock represented by the Certificate multiplied by the Exchange Ratio and
cash in lieu of any fractional share interest (the "Merger Consideration"),  and
such Certificate shall then be cancelled. If payment of the Merger Consideration
is  to be made to a  person other than the person  in whose name the Certificate
surrendered  is  registered,  the  Certificate  must  be  properly  endorsed  or
otherwise  in proper  form for transfer  and the person  requesting such payment
must pay any  transfer or other  taxes required by  reason of the  payment to  a
person  other  than  the registered  holder  of the  Certificate  surrendered or
establish to the  satisfaction of the  Surviving Corporation that  such tax  has
been paid

                                       35
<PAGE>
or  is not applicable.  Until surrendered, each  Certificate shall represent for
all purposes only the right to receive  shares of HBOC Common Stock and cash  in
lieu  of  any  fractional share  interest,  without  any interest  on  the value
thereof.

    Notwithstanding the foregoing,  neither HBOC nor  the Surviving  Corporation
shall  be liable to  any holder of Certificates  formerly representing shares of
CliniCom Common Stock  for any  property delivered or  amount paid  to a  public
official pursuant to any applicable abandoned property, escheat or similar law.

    PAYMENT  OF DIVIDENDS.   No  cash or  stock dividend  payable to  holders of
record of HBOC Common Stock at any time subsequent to the Effective Time of  the
Merger will be paid or delivered to any holder of a Certificate unless and until
such  Certificate  has been  surrendered  to the  Exchange  Agent in  the manner
described above. However, upon such surrender, there shall be paid or  delivered
to  the holder  of record  of the  certificates of  HBOC Common  Stock issued in
exchange therefor, the cash  and other property  resulting from such  dividends,
without interest thereon.

   
    LIMITATIONS  ON TRANSFERABILITY OF HBOC COMMON STOCK.  Shares of HBOC Common
Stock received by  certain persons  deemed to  be "affiliates"  of CliniCom  for
purposes  of  Rule  145  under  the  Securities  Act  will  be  subject  to  the
restrictions imposed by such rule. In accordance with Rule 145, an affiliate  of
CliniCom  receiving HBOC  Common Stock  issued in the  Merger may  not sell such
shares except pursuant to  the volume and manner  of sale limitations and  other
requirements   specified  therein  or  pursuant  to  an  effective  registration
statement under the Securities Act. It is a condition to the obligation of  HBOC
to  consummate the Merger that  HBOC shall have received  from each affiliate of
CliniCom a  letter  agreement confirming  that  such  person will  not  sell  or
otherwise  dispose of the shares of HBOC Common Stock received by such person as
a result of the Merger other than in  compliance with Rule 145 or pursuant to  a
registration  statement or pursuant  to any other  available exemptions from the
registration requirements of the Securities Act. In general, directors, officers
and substantial beneficial owners of a corporation's securities may be deemed to
be "affiliates" of a corporation.  In addition, certain CliniCom affiliates  are
subject  to certain restrictions on transfer of both CliniCom Common Stock prior
to, and HBOC Common Stock following, the Effective Date of the Merger to  ensure
pooling treatment of the transaction.

    HART-SCOTT-RODINO.   The Merger is subject  to the requirements of the H-S-R
Act, which provides that certain transactions (including the Merger) may not  be
consummated  until  certain  information  has been  furnished  to  the Antitrust
Division  and  the  FTC  and  certain  waiting  period  requirements  have  been
satisfied.  HBOC and CliniCom  filed the required  information and material with
the Antitrust Division and the FTC on July 21, 1995, and were notified on August
4, 1995, that  they had been  granted early termination  of the waiting  period.
Satisfaction  of the waiting period requirement  does not preclude the Antitrust
Division, the FTC or  any other party  from challenging or  seeking to delay  or
enjoin the Merger on antitrust or other grounds.

    NO  SOLICITATION.  CliniCom has  agreed that prior to  the Effective Time of
the Merger or earlier termination of  the Merger Agreement, CliniCom shall  not,
directly  or indirectly, initiate, solicit, encourage, endorse or enter into any
agreement with respect to or take any action to facilitate, any inquiries or the
making of any proposal or offer for any tender or exchange offer, proposal for a
merger, share exchange or other  business combination involving CliniCom or  any
proposal  or offer  to acquire  in any manner  a substantial  equity interest in
CliniCom or a substantial portion of the  assets of CliniCom with any person  or
entity;  provided, however, that the Board  of Directors of CliniCom may furnish
information to or enter  into discussions or  negotiations with any  unsolicited
person or entity if the Board of Directors of CliniCom determines in good faith,
after  receiving written advice from its outside counsel, that such action would
be required  under applicable  law  in the  exercise  of its  fiduciary  duties.
CliniCom  has agreed to notify  HBOC-GA if any such  proposals are received, any

Merger Agreement not to exceed $500,000 and a fee in the amount of $1,500,000.

ACCOUNTING TREATMENT

   
    It is a condition of the closing  of the Merger that the parties shall  have
received  letters from  Arthur Andersen  LLP, independent  public accountants to
CliniCom and HBOC, that the  Merger may be accounted  for under the "pooling  of
interests"   method  of  accounting,  in   accordance  with  generally  accepted
accounting principles.
    

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

    It is a  condition to the  obligation of CliniCom  to consummate the  Merger
that  CliniCom  receive an  opinion from  its counsel,  Davis, Graham  & Stubbs,
L.L.C., as to  certain tax  matters affecting  CliniCom or  holders of  CliniCom
Common  Stock, and it  is a condition to  the obligation of  HBOC and HBOC-GA to
consummate the  Merger that  HBOC  and HBOC-GA  receive  an opinion  from  their
counsel, Jones, Day, Reavis & Pogue, as to certain tax matters affecting HBOC or
HBOC-GA.

    CliniCom  has  been  advised by  Davis,  Graham  & Stubbs,  L.L.C.  that the
principal federal income  tax consequences  of the  Merger to  CliniCom and  its
stockholders are expected to be substantially as follows:

        (i)  The Merger  will qualify  as a  reorganization pursuant  to Section
    368(a) of the Internal Revenue Code of 1986, as amended (the "Code");

        (ii) No gain or loss will be recognized by CliniCom as the result of the
    consummation of the Merger;

       (iii) No gain or loss will  be recognized by a CliniCom stockholder  upon
    the  exchange of  the shares  of CliniCom  Common Stock  for shares  of HBOC
    Common Stock pursuant to the Merger, except  on the receipt of cash in  lieu
    of a fractional share interest in HBOC Common Stock;

       (iv)  The aggregate  adjusted tax  basis of  shares of  HBOC Common Stock
    received  (including  fractional  share  interests  deemed  received)  by  a
    CliniCom  stockholder as the  result of the  Merger will be  the same as the
    aggregate adjusted  tax  basis  of  the  shares  of  CliniCom  Common  Stock
    surrendered in exchange therefor;

        (v)  The  holding period  of the  shares of  HBOC Common  Stock received
    (including  fractional  share  interests  deemed  received)  by  a  CliniCom
    stockholder as a result of the Merger will include the holding period of the
    shares  of CliniCom Common Stock  surrendered in exchange therefor, provided
    that such CliniCom Common Stock is held  as a capital asset by the  CliniCom
    stockholder at the consummation of the Merger; and

       (vi)  A CliniCom  stockholder who receives  cash in lieu  of a fractional
    interest in shares of HBOC Common Stock will be treated as if the fractional
    share were distributed as part of the exchange and then as having received a
    cash distribution in  redemption of  such fractional share,  which would  be
    taxed as provided in Section 302 of the Code.

    HBOC  and HBOC-GA have been  advised by Jones, Day,  Reavis & Pogue that the
principal federal income tax consequences of the Merger to HBOC and HBOC-GA  are
expected to be substantially as follows:

        (i)  The Merger  will qualify  as a  reorganization pursuant  to Section
    368(a) of the Code; and

        (ii) No  gain or  loss will  be recognized  by either  HBOC, HBOC-GA  or
    CliniCom as the result of the consummation of the Merger.

    The advice referred to above and the tax opinions of Davis, Graham & Stubbs,
L.L.C.  and  Jones, Day,  Reavis &  Pogue are,  and will  be, premised  upon the
receipt of certain customary representations

                                       38
<PAGE>
and  assumptions   referred   to  in   the   opinion  letters.   The   necessary
representations  have not  yet been  received, but  are expected  to be received
prior to the Effective Time of the Merger. In particular, the advice is premised
on, and the opinions will be issued in reliance on, certain representations from
CliniCom and/or certain  holders of CliniCom  Common Stock with  respect to  the
satisfaction  of  the "continuity  of interest"  requirement of  the regulations
interpreting Section 368 of the Code.  In general, the "continuity of  interest"
requirement  is considered to be  satisfied if 50% or  more of the capital stock
issued in a merger is held by the recipient stockholders of the acquired  entity
following  the  merger other  than under  a plan  or intent  to dispose  of such
shares. To satisfy this requirement,  the Merger Agreement provides that,  prior
to  the Effective Time of the Merger,  CliniCom will deliver to HBOC and HBOC-GA
letters to the  reasonable satisfaction of  HBOC and HBOC-GA  from CliniCom  and
certain  of its  stockholders that  provide assurance that  there is  no plan or
intention on the part of the holders  of CliniCom Common Stock (or knowledge  of
such  plan or intent with respect to holders  of less than 5% of CliniCom Common
Stock) to sell,  exchange or otherwise  dispose of  a number of  shares of  HBOC
Common  Stock received in the Merger  that would reduce CliniCom's stockholders'
ownership of HBOC  Common Stock received  in the  Merger to a  number of  shares
having  a value, as of the Effective Time of the Merger, of less than 50% of the
value of all of the outstanding  CliniCom Common Stock immediately prior to  the
Effective  Time of the  Merger. No ruling  has been requested  from the Internal
Revenue Service in  connection with  the Merger,  and the  opinions referred  to
above would neither be binding upon the Internal Revenue Service nor preclude it
from adopting a contrary position.

    THE  FOREGOING DISCUSSION IS  INTENDED ONLY AS A  SUMMARY OF CERTAIN FEDERAL
INCOME TAX CONSEQUENCES  OF THE MERGER  AND DOES  NOT PURPORT TO  BE A  COMPLETE
ANALYSIS  OR LISTING OF ALL POTENTIAL TAX EFFECTS RELEVANT TO A DECISION WHETHER
TO VOTE  IN  FAVOR  OF  APPROVAL  AND ADOPTION  OF  THE  MERGER  AGREEMENT.  THE
DISCUSSION  DOES NOT  ADDRESS THE  TAX CONSEQUENCES  THAT MAY  BE RELEVANT  TO A
PARTICULAR HOLDER OF SHARES OF CLINICOM COMMON STOCK THAT IS SUBJECT TO  SPECIAL
TREATMENT  UNDER CERTAIN FEDERAL INCOME TAX LAWS, SUCH AS DEALERS IN SECURITIES,
BANKS, INSURANCE COMPANIES, TAX EXEMPT ORGANIZATIONS, NON-UNITED STATES  PERSONS
AND  HOLDERS  OF  SHARES OF  CLINICOM  COMMON  STOCK WHO  ACQUIRED  THEIR SHARES
PURSUANT TO THE EXERCISE OF OPTIONS TO PURCHASE SHARES OF CLINICOM COMMON  STOCK
("CLINICOM  OPTIONS") OR OTHERWISE AS COMPENSATION, NOR ANY CONSEQUENCES ARISING
UNDER THE LAWS OF ANY STATE, LOCALITY OR FOREIGN JURISDICTION. MOREOVER, THE TAX
CONSEQUENCES TO HOLDERS OF CLINICOM OPTIONS ARE NOT DISCUSSED. THE DISCUSSION IS
BASED UPON THE CODE, TREASURY REGULATIONS THEREUNDER AND ADMINISTRATIVE  RULINGS
AND  COURT DECISIONS AS OF THE DATE HEREOF.  ALL OF THE FOREGOING ARE SUBJECT TO
CHANGE AND  ANY  SUCH  CHANGE  COULD AFFECT  THE  CONTINUING  VALIDITY  OF  THIS
DISCUSSION.  HOLDERS OF  SHARES OF  CLINICOM COMMON  STOCK ARE  URGED TO CONSULT
THEIR OWN TAX  ADVISORS CONCERNING  THE FEDERAL,  STATE, LOCAL  AND FOREIGN  TAX
CONSEQUENCES OF THE MERGER TO THEM.

NO APPRAISAL RIGHTS

    The  holders of  shares of  CliniCom Common  Stock will  not be  entitled to
appraisal rights pursuant  to Section  262 of the  DGCL in  connection with  the
Merger.

INTERESTS OF CERTAIN PERSONS IN MATTERS TO BE ACTED UPON

    In considering the  Merger, stockholders  of CliniCom should  be aware  that
certain  members  of management  and  the Board  of  Directors of  CliniCom have
interests in  the  Merger  that are  in  addition  to, or  different  from,  the
interests of stockholders of CliniCom generally.

   
    EXECUTIVE  RETENTION PLAN.  Pursuant  to the CliniCom Incorporated Executive
Retention Plan (the "Retention Plan"), participants therein may become  entitled
to  certain cash  payments following the  Merger. Generally,  the Retention Plan
provides for certain cash payments to be made to participants in the event of  a
"Qualified  Termination"  described below,  following a  "Change of  Control." A
Change of Control for purposes of the Retention Plan is deemed to have  occurred
if  the stockholders  of CliniCom  approve a  merger other  than a  merger which
results in the voting  securities of CliniCom representing  at least 80% of  the
combined voting power of the surviving corporation. Accordingly, the Merger will
constitute a Change of Control for purposes of the Retention Plan.
    

                                       43
<PAGE>
   
    In  the event of a Qualified Termination following the Merger, a participant
in the Retention Plan will be entitled to receive in cash (i) the  participant's
annual  base salary  (as in  effect immediately prior  to the  Merger); (ii) the
amount of the participant's  bonus (net of sales  commission) for the  preceding
year  (the "Bonus"); and  (iii) one-twelfth of  the Bonus received  in the prior
year times  the number  of months  worked in  the year  in which  the  Qualified
Termination occurs. A participant may also receive an additional amount of up to
one-half  of  such  participant's annual  base  pay upon  recommendation  of the
committee appointed to administer the Retention Plan. Finally, each  participant
is  entitled to continue to participate  in CliniCom's welfare benefit plans for
one year  following the  date of  a Qualified  Termination. Notwithstanding  the
foregoing,  to  the extent  the  payments described  above,  either alone  or in
conjunction with other compensation payable to participants, would constitute an
"excess parachute payment" for purposes of  Section 280G(b)(2) of the Code,  the
amount of such payments shall be reduced so as not to constitute such an "excess
parachute  payment." Pursuant to the Retention  Plan, CliniCom will be funding a
trust in  the amount  of approximately  $2,000,000 to  make payments  prescribed
thereunder.
    

    For  purposes  of  the Retention  Plan,  a "Qualified  Termination"  means a
termination of a participant's employment within one year after the Merger:  (i)
by  HBOC for any reason other than "Cause"  or (ii) by the participant for "Good
Reason."  Generally,   "Cause"  means   serious,  willful   misconduct  in   the
participant's  obligations to  his or  her employer  or gross  violations of the
employer's established policies and  procedures. "Good Reason" means  generally:
(i) a change in the participant's duties which causes the participant's position
to  become one of less responsibility, importance  or scope; (ii) reduction in a
participant's base salary; (iii) elimination of benefit plans; and (iv)  certain
relocations.

    The  following persons  are participants in  the Retention  Plan: William H.
Brehm, Chief Executive Officer and Chairman of the Board; Catherine K.  Milburn,
Vice  President  of  Finance  and Administration  and  Chief  Financial Officer,
Secretary and Treasurer; Linda J. McConnon, Vice President and General  Counsel;
Brian E. Higgins, Vice President of Business Development; Michael E. Myers, Vice
President  of  Marketing  and  Product  Development;  Dennis  J.  Gardner,  Vice
President of  Operations; Mark  W. Fidler,  Vice President  of Client  Services;
Craig  J. Lund, Vice President of Direct  Channel Sales; and Marjorie M. Rodell,
Director of Critical Care.

   
    REGISTRATION RIGHTS.  Pursuant to the  Merger Agreement, HBOC has agreed  to
provide  certain registration  rights in  certain limited  circumstances to Wind
Point Partners (or  its partners), Marshall  D. Miller, his  children, David  J.
Miller,  Susan D. Lyons  and Steven L.  Miller, Phileona Foundation,  which is a
tax-exempt, non-profit organization of which  Marshall Miller is a trustee,  and
Dorado  Investment Company, in  which Marshall Miller holds  a 99% interest (the
"Selling Stockholders"). In the event that the average weekly reported volume of
trading of the HBOC Common Stock, as reported through the NASDAQ-NM, during  any
four (4) calendar week period ending on any date within six months following the
Closing  Date constitutes less than two percent  of the number of shares of HBOC
Common Stock outstanding as  of such date,  HBOC will be  obligated to file  one
registration statement covering the shares owned by the Selling Stockholders.
    

    INDEMNIFICATION  AGREEMENTS.  HBOC-GA has  agreed to provide indemnification
to the  directors and  officers  of CliniCom,  in  accordance with  the  current
provisions  of the  Certificate of Incorporation  and Bylaws of  CliniCom, for a
period of five  years from  the Effective  Time of  the Merger  with respect  to
matters   arising  prior  thereto  including,  without  limitation,  the  Merger
Agreement and the transactions contemplated thereby.

              COMPARISON OF RIGHTS OF HOLDERS OF SHARES OF EACH OF
                  HBOC COMMON STOCK AND CLINICOM COMMON STOCK

INTRODUCTION

    HBOC and  CliniCom are  each incorporated  under the  laws of  the State  of
Delaware.  The  holders of  shares  of CliniCom  Common  Stock, whose  rights as
stockholders are currently governed by Delaware law, the CliniCom Certificate of
Incorporation (the "CliniCom Charter"), and the Amended and Restated By-laws  of
CliniCom  (the  "CliniCom  Bylaws"), will,  upon  the exchange  of  their shares
pursuant to the Merger, become holders of shares of HBOC Common Stock, and their
rights as  such  will be  governed  by Delaware  law,  the HBOC  Certificate  of
Incorporation  (the "HBOC Charter") and the  Amended and Restated Bylaws of HBOC
(the "HBOC Bylaws"). The material differences  between the rights of holders  of
shares  of CliniCom Common Stock and of the  rights of holders of shares of HBOC
Common Stock result from differences in their governing corporate documents  and
are summarized below.

    The  following summary does  not purport to  be a complete  statement of the
rights of holders of shares of HBOC Common Stock under applicable Delaware  law,
the  HBOC Charter and HBOC Bylaws or  a comprehensive comparison with the rights
of the holders of shares of CliniCom Common Stock under applicable Delaware law,
the CliniCom  Charter and  CliniCom Bylaws,  or a  complete description  of  the
specific   provisions  referred  to  herein.   The  identification  of  specific
differences is not  meant to  indicate that  other equally  or more  significant
differences do not exist. This summary is qualified in its entirety by reference
to  the Delaware  General Corporation Law  ("DGCL") and  the governing corporate
documents of HBOC and  CliniCom, to which holders  of shares of CliniCom  Common
Stock are referred.

AUTHORIZED CAPITAL STOCK

    The  DGCL  requires that  a corporation's  certificate of  incorporation set
forth the total number of shares of  all classes of stock which the  corporation
has  authority to  issue and  a statement  of the  designations and  the powers,
preferences and  rights, and  the  qualifications, limitations  or  restrictions
thereof.  The  HBOC  Charter  provides  that HBOC  has  authority  to  issue (i)
60,000,000 shares of HBOC  Common Stock and (ii)  1,000,000 shares of  preferred
stock,  no  par  value. The  CliniCom  Charter  provides that  CliniCom  has the
authority to  issue (i)  30,000,000 shares  of CliniCom  Common Stock  and  (ii)
5,000,000  shares of preferred  stock, par value $.001  per share (the "CliniCom
Preferred Stock").

BOARD OR STOCKHOLDER APPROVED PREFERRED STOCK

    The DGCL permits a corporation's  certificate of incorporation to allow  its
board  of directors to issue, without  stockholder approval, series of preferred
or preference stock and to  designate their rights, preferences, privileges  and
restrictions.  The HBOC Charter grants such power to the HBOC Board of Directors
(the "HBOC Board"). The HBOC Board has designated one series of preferred stock,
the Series A Junior Participating Preferred Stock. See "Incorporation of Certain
Information by Reference." The  CliniCom Charter also grants  such power to  the
CliniCom Board. There are no shares of CliniCom Preferred Stock outstanding.

VOTING RIGHTS

    The  DGCL states that,  unless a corporation's  certificate of incorporation
or, with respect to clauses (ii)  and (iii), the bylaws, specify otherwise,  (i)
each  share of  its capital stock  is entitled to  one vote, (ii)  a majority of
voting power of the shares entitled to vote, present in person or represented by
proxy, shall constitute a  quorum at a stockholders'  meeting, and (iii) in  all
matters  other  than the  election  of directors,  the  affirmative vote  of the
majority of the  voting power  of shares, present  in person  or represented  by
proxy  at the meeting and  entitled to vote on the  subject matter, shall be the
action of  the stockholders.  The holders  of shares  of HBOC  Common Stock  are
entitled to one vote per share on all matters to be voted on by the stockholders
of HBOC. The holders of shares of CliniCom Common Stock are entitled to one vote
per share on all matters to be voted on by the stockholders of CliniCom.

                                       45
<PAGE>
NUMBER OF DIRECTORS

    Under   the  DGCL,  unless  a  corporation's  certificate  of  incorporation
specifies the number  of directors, such  number shall  be fixed by,  or in  the
manner  provided in, its bylaws. If a corporation's certificate of incorporation
expressly authorizes its board  of directors to amend  its bylaws, its board  of
directors  may change the authorized number of  directors by an amendment to the
corporation's bylaws,  if  fixed therein,  or  in  such manner  as  is  provided
therein. If such certificate of incorporation specifies the number of directors,
the  number of  directors can  only be  changed by  amending the  certificate of
incorporation. The HBOC Bylaws provide that  the number of members of the  board
of  directors shall be not less than three nor more than fifteen, such number to
be established  by  the  board  of directors  or  stockholders.  The  number  of
directors  on the HBOC Board is currently  nine (9). The CliniCom Bylaws provide
that the number of  directors shall be  seven (7), which  number may be  changed
from  time to time by resolution of  the CliniCom Board. The number of directors
constituting the CliniCom Board is currently six.

ELECTION OF BOARD OF DIRECTORS

    The DGCL  provides that  a corporation's  directors shall  be elected  by  a
plurality  of the votes of the shares  present in person or represented by proxy
at the meeting  and entitled to  vote on  the election of  directors. Under  the
DGCL, a corporation's certificate of incorporation may provide that stockholders
of  a corporation  can elect  directors by  cumulative voting.  Neither the HBOC
Charter nor the CliniCom Charter provide for cumulative voting.

VOTE ON MERGER, CONSOLIDATION OR SALE OF SUBSTANTIALLY ALL ASSETS

    The DGCL generally requires approval of any merger, consolidation or sale of
substantially all the assets  of a corporation at  a meeting of stockholders  by
vote  of the holders of a majority  of all outstanding shares of the corporation
entitled to  vote  thereon.  The  certificate of  incorporation  of  a  Delaware
corporation  may provide for a greater vote. The HBOC Charter generally requires
the affirmative vote  of four-fifths  of the  outstanding HBOC  Common Stock  to
approve  certain business combinations, except  under certain circumstances. See
"-- Anti-Takeover Protection." The CliniCom Charter does not provide for a  vote
greater  than a majority of all outstanding  shares of CliniCom Common Stock for
approval of any merger, consolidation or sale of substantially all the assets of
CliniCom.

SPECIAL MEETINGS OF STOCKHOLDERS

    Under the DGCL, special stockholder meetings of a corporation may be  called
by  its board of directors and  by any person or persons  authorized to do so by
its certificate of incorporation or bylaws.  Under the HBOC Charter and  Bylaws,
special  meetings  of  the stockholders,  for  any purpose  or  purposes, unless
otherwise prescribed by statute, may be called  by the Chairman of the Board  or
the  President or by  holders of four-fifths  of the outstanding  shares of HBOC
Common Stock and shall be  called by the Chairman of  the Board or President  at
the  request in writing of three-fourths of the directors of HBOC. Such requests
shall state the purpose or purposes of the proposed meeting. The CliniCom Bylaws
provide that special meetings of stockholders  may be called for any purpose  by
the  President,  by the  Secretary if  directed  by the  CliniCom Board,  by the
holders of at least 20% of  any issued and outstanding CliniCom Preferred  Stock
or by the holders of all issued and outstanding stock of CliniCom representing a
majority of the voting power of CliniCom.

STOCKHOLDER ACTION BY WRITTEN CONSENT

    Under  the DGCL, any action by a corporation's stockholders must be taken at
a meeting of such  stockholders, unless a consent  in writing setting forth  the
action  so taken is signed by the  stockholders having not less than the minimum
number of votes necessary to authorize or take such action at a meeting at which
all shares entitled to vote thereon  were present and voted. Actions by  written
consent,  however, may not be taken if otherwise provided for in the certificate
of incorporation.  The  HBOC Charter  expressly  prohibits written  consents  by
stockholders; the CliniCom Charter does not.

                                       46
<PAGE>
AMENDMENT OF CERTIFICATE OF INCORPORATION

   
    The DGCL allows amendment of a corporation's certificate of incorporation if
its board of directors adopts a resolution setting forth the amendment proposed,
declaring  its  advisability,  and  the  stockholders  thereafter  approve  such
proposed amendment, either  at a  special meeting called  by the  board for  the
purpose  of approval of such amendment by the stockholders or, if so directed by
the board, at the  next annual stockholders' meeting.  At any such meeting,  the
proposed  amendment generally must be approved  by a majority of the outstanding
shares entitled to vote. The  holders of the outstanding  shares of a class  are
entitled  to vote as a separate class  upon a proposed amendment, whether or not
entitled to vote thereon by the  certificate of incorporation, if the  amendment
would  increase or  decrease the aggregate  number of authorized  shares of such
class, increase or decrease the par value of the shares of such class, or  alter
or change the powers, preferences, or special rights of the shares of such class
so  as to affect them adversely. If any proposed amendment would alter or change
the powers, preferences, or special rights of one or more series of any class so
as to affect  them adversely, but  not affect  the entire class,  then only  the
shares  of the series so affected by the amendment will be considered a separate
class for  the  purposes  of  a  vote  on  the  amendment.  Under  the  DGCL,  a
corporation's  certificate of incorporation also may  require, for action by the
board or by the holders of any class or series of voting securities, the vote of
a greater number or proportion than is required by the DGCL and the provision of
the certificate of incorporation requiring such greater vote cannot be  altered,
amended  or repealed  except by  such greater  vote. The  HBOC Charter  does not
contain provisions requiring a vote greater  than that specified in the DGCL  to
amend  the  HBOC  Charter,  except for  those  provisions  relating  to business
combinations. See " -- Anti-Takeover Protection." The CliniCom Charter does  not
contain a provision requiring a vote greater than that specified in the DGCL.
    

AMENDMENT OF BYLAWS

    Under  the DGCL, the power to adopt,  amend or repeal a corporation's bylaws
resides with the stockholders entitled to  vote thereon, and with the  directors
of  such corporation if such  power is conferred upon  the board of directors by
the certificate of incorporation. The HBOC Charter authorizes the HBOC Board  to
make,  alter or repeal the HBOC Bylaws. The CliniCom Charter also authorizes the
CliniCom Board to make, repeal, alter, amend and rescind the CliniCom Bylaws.

LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS

    The DGCL provides  that a corporation  may limit or  eliminate a  director's
personal  liability for monetary damages to  the corporation or its stockholders
for breach of fiduciary  duty as a  director, except for  liability (i) for  any
breach   of  the  director's  duty  of   loyalty  to  such  corporation  or  its
stockholders, (ii) for  acts or  omissions not in  good faith  or which  involve
intentional  misconduct  or a  knowing  violation of  law,  (iii) for  paying or
approving a stock repurchase in  violation of Section 174  of the DGCL, or  (iv)
for  any  transaction  from  which the  director  derived  an  improper personal
benefit. The HBOC Charter provides for elimination of personal liability subject
to the statutory exceptions. The CliniCom Charter provides that, to the  fullest
extent  permitted by the DGCL, a director shall not be liable to CliniCom or its
stockholders for monetary damages for breach of fiduciary duty as a director.

    Under the  DGCL, directors  and  officers as  well  as other  employees  and
individuals  may be  indemnified against  expenses (including  attorneys' fees),
judgments, fines and  amounts paid  in settlement in  connection with  specified
actions,  suits  or  proceedings,  whether  civil,  criminal,  administrative or
investigative (other than an action by or  in the right of the corporation as  a
derivative  action) if they acted in good  faith and in a manner they reasonably
believed to be in, or not opposed to, the best interest of the corporation, and,
with respect to  any criminal action  or proceeding, if  they had no  reasonable
cause  to  believe  their  conduct  was unlawful.  The  HBOC  Bylaws  provide to
directors and officers of HBOC indemnification to the fullest extent provided by
law. Article IX of  the HBOC Bylaws  also provides that  expenses incurred by  a
person  in defending a civil or criminal action, suit or proceeding by reason of
the fact that he or she is a director, officer, employee or agent may be paid in
advance of  the final  disposition  of such  action,  suit or  proceeding,  upon
receipt of an undertaking by or

                                       47
<PAGE>
on  behalf of  such director,  officer, employee or  agent to  repay such amount
unless it  shall ultimately  be determined  that he  or she  is entitled  to  be
indemnified  by HBOC as  authorized by relevant  Delaware law. Article  V of the
CliniCom Bylaws provides for  indemnification of directors  and officers to  the
fullest  extent  authorized by  the DGCL,  including  the right  to be  paid for
expenses  in  advance  of  the   final  disposition  of  any  civil,   criminal,
administrative  or investigative action provided  that such director, officer or
legal representative undertakes, to  the extent required by  the DGCL, to  repay
such amounts if it is ultimately determined that such director, officer or legal
representative was not entitled to such indemnification.

PAYMENT OF DIVIDENDS

    The  DGCL permits the payment of dividends  and the redemption of shares out
of a corporation's surplus. Under the DGCL, if a dividend is paid out of capital
surplus, stockholders need not be so notified, and the dividends may in  certain
cases  also be paid out of net profits  for the fiscal year in which declared or
out of net profits for the preceding  fiscal year. Neither the HBOC Charter  nor
the  HBOC  Bylaws have  any provisions  limiting the  payment of  dividends. The
CliniCom Charter  does not  limit the  payment of  dividends, but  the  CliniCom
Bylaws  allow the Board of Directors, before  payment of dividends, to set aside
out of any funds available for dividends  a reserve or reserves for any  purpose
the  directors  think  in their  sole  discretion  is in  the  best  interest of
CliniCom.

ANTI-TAKEOVER PROTECTION

    Under the DGCL, a merger or consolidation generally must be approved by  the
affirmative  vote of the holders of a  majority of all of the outstanding shares
of stock entitled to vote thereon. However, no stockholder approval is  required
if  the acquiring corporation owns 90% or  more of the outstanding shares of the
acquired corporation.

    In addition to  the DGCL's general  requirements, Section 203  of the  DGCL,
"Business  Combinations with  Interested Stockholders,"  prohibits a corporation
that does not  opt out  of its provisions  from entering  into certain  business
combination  transactions with  "interested stockholders"  (generally defined to
include persons beneficially owning 15% or more of the corporation's outstanding
capital stock) unless certain super-majority votes are obtained. HBOC has  opted
out  of Section  203 in  its Bylaws.  However, the  HBOC Charter  places certain
restrictions on "Business  Combinations" (such  as a  merger) with  "Controlling
Persons"  (generally, a person holding  more than 10% of  the HBOC Common Stock)
unless, generally speaking, the  Business Combination has  been approved by  the
affirmative  vote of the  holders of four-fifths of  the outstanding HBOC Common
Stock not  held by  the  Controlling Person  or its  related  entities or  by  a
majority  of  directors who  were directors  prior to  the time  the Controlling
Person became  a  Controlling  Person  and  who  are  not  affiliated  with  the
Controlling  Person. Such  provisions do not  apply to the  Merger. CliniCom has
opted out of Section 203 in the CliniCom Charter.

APPRAISAL RIGHTS

    Under the DGCL, stockholders  of corporations being  acquired pursuant to  a
merger  have  the right  to  serve upon  the  corporation a  written  demand for
appraisal  of  their  shares   when  the  stockholders   receive  any  form   of
consideration   for  their  shares  other  than  (a)  shares  of  the  surviving
corporation, (b)  shares of  any  other corporation  (i)  listed on  a  national
securities  exchange, (ii) designated as a national market system security on an
inter-dealer quotation system by the National Association of Securities Dealers,
Inc. or (iii) held of record by more than 2,000 shareholders or (c) cash in lieu
of fractional  shares  or  any combination  thereof.  Stockholders  entitled  to
appraisal  rights subsequently  receive cash from  the corporation  equal to the
value of their  shares as  established by judicial  appraisal. Corporations  may
enlarge   these  statutory   rights  by   including  in   their  certificate  of
incorporation a provision allowing appraisal rights  in any merger in which  the
corporation  is  a constituent  corporation. Neither  the  HBOC Charter  nor the
CliniCom Charter contains such a provision.

                                BUSINESS OF HBOC

GENERAL

    OVERVIEW.  HBOC  is a  leading healthcare information  systems company  that
develops  integrated patient care, clinical,  financial and strategic management
software solutions for  healthcare providers, payers  and integrated  healthcare
delivery  systems.  HBOC designs  open  systems solutions  which  facilitate the
integration of clinical, financial and administrative data from a wide range  of
customer systems and software. HBOC's broad product portfolio can be implemented
on  a stand-alone, combined or enterprisewide basis. HBOC's newer products offer
open systems solutions that enable customers to add incremental capabilities  to
existing information systems, without making prior capital investments obsolete.
HBOC  also  provides  networking  technologies  and  outsourcing  services under
contract management  agreements  whereby its  staff  manages and  operates  data
centers,  information systems, organizations and  business offices of healthcare
institutions of various sizes and structures.

    HBOC markets its products and  services to hospitals, integrated  healthcare
delivery  systems,  physicians'  offices, managed  care  providers,  home health
providers, pharmacies and reference laboratories, and currently has one or  more
applications  installed in  approximately 2,600  of the  5,900 hospitals  in the
United States. HBOC also sells its products and services internationally through
its subsidiaries in the United Kingdom and Canada and distribution agreements in
Saudi Arabia, Australia, Puerto Rico and New Zealand.

    INDUSTRY.   The  healthcare industry  is  undergoing significant  and  rapid
change. Healthcare delivery costs have increased dramatically in recent years as
compared to the overall rate of inflation. The growing influence of managed care
has  resulted in increasing pressure on participants in the healthcare system to
contain costs.  Accordingly, the  healthcare system  has migrated  towards  more
managed care reimbursement, including discounted fee for service and capitation.
Under  capitation, providers  are paid  a pre-determined  fee per  individual to
provide all healthcare services, thereby assuming the potential financial  risks
of  escalating healthcare costs.  In order to  deliver care in  a cost effective
manner, providers are forming integrated healthcare delivery systems ("IHDS") to
provide care across the continuum.

    IHDS are vertical  networks of care  providers that may  include acute  care
hospitals, physicians, out-patient care facilities and home healthcare. The goal
of  IHDS is to deliver comprehensive healthcare  in a cost effective manner and,
accordingly, their success is dependent  on effectively managing and  delivering
information  to the caregivers. As IHDS are evolving, the demand for information
services is increasing as  both financial and  clinical information is  required
across the multiple points-of-care.

    Traditionally,  the hospital information systems market has been the largest
segment of healthcare  information services. According  to Sheldon Dorenfest,  a
healthcare   consulting  company,   in  1994   the  healthcare   industry  spent
approximately $8.5  billion  for  products and  services  to  support  automated
information  systems, and  the growth rate  is expected to  continue to increase
over the next several years as healthcare information expenditures are  expected
to  rise  to  $13  billion  by  1997.  In  addition  to  this  expanding  market
opportunity, the demand  for healthcare information  systems is also  increasing
because hospitals and other providers are under pressure to quantify and control
their  costs. As a result, they are  spending more of their operating budgets on
systems which enable  them to  access such  information. According  to the  1995
Annual  HIMSS/HP  Leadership Survey,  an  industry survey  conducted  by Hewlett
Packard at the Healthcare Information and Management Systems Society conference,
75% of the  respondents stated  that their information  system investments  will
increase at a rate of 20% or more over the next two years.

    Healthcare  information systems are evolving to meet the needs of a changing
marketplace.  Initially,   healthcare  information   systems  were   financially
oriented, focusing on the ability to capture charges and generate patient bills.
As   cost   containment   efforts   have   forced   providers   and   payors  to

                                       49
<PAGE>
focus on their  costs, manage risk  and provide outcomes  and quality  analysis,
system  needs have evolved  from the traditional billing  information to a wider
range of  needs  including  enterprisewide  systems  capable  of  capturing  and
analyzing  data at all points-of-care as well  as data repositories to store the
data. Historically, cost  containment efforts have  been hampered by  a lack  of
integrated clinical and financial information. As reimbursement is shifting more
toward  risk sharing and capitation, providers  and payers need to better manage
risk  by  controlling  costs,  demonstrating  quality,  measuring  outcomes  and
influencing  utilization. Each of these  goals requires the collection, analysis
and interpretation of clinical and financial information related to the delivery
of healthcare.

    The availability of  a complete, timely  and cost-effective  patient-focused
information  system is essential to controlling healthcare costs while providing
high quality  patient care.  In  many cases,  information necessary  to  provide
effective  patient  care  is  located  at several  different  sites  and  is not
immediately  available  to   the  care  giver.   To  implement  a   computerized
patient-focused  information  system  that  accesses  patient  information  in a
cost-effective manner,  current  and  historical  paper  records  must  be  made
available  by computer  to all  points-of-care. In  order to  effectively manage
information in the  current healthcare environment,  providers, payers and  IHDS
need  information  systems that  can interface  fully  with existing  and future
systems,  capture  data  at  the  point-of-care,  communicate  data  across  the
continuum  of care and process and store large volumes of data necessary for the
development of the computer-based patient record.

STRATEGY

    HBOC's strategy  is  to  provide a  comprehensive  range  of  computer-based
information  systems  and  services  designed  to  meet  the  evolving  needs of
healthcare enterprises. The key elements of this strategy are to:

    LEVERAGE EXISTING  CUSTOMER  BASE.    HBOC  is  a  leader  in  the  hospital
information  systems  marketplace with  one  or more  applications  installed in
approximately 2,600 of  the 5,900 hospitals  in the U.S.  HBOC expands its  core
customer base through its sales and marketing efforts and strategic acquisitions
such  as  IBAX Healthcare  Systems and  HSG,  which added  475 and  500 hospital
customers, respectively.  This expanded  customer base  offers HBOC  significant
opportunities  to  sell both  additional  applications of  its  established core
product line and its new Pathways patient-centered enterprisewide solutions.  In
addition,   HBOC  believes  its  customer  relationships  and  familiarity  with
customers' existing  systems should  give HBOC  an advantage  over many  of  its
competitors  in  marketing  applications to  meet  the evolving  needs  of these
customers. HBOC also seeks to  further leverage its relationships with  existing
customers  to access additional healthcare organizations throughout newly-formed
IHDS.

    PROVIDE ENTERPRISEWIDE SOLUTIONS TO THE EVOLVING HEALTHCARE INDUSTRY.   HBOC
offers  one of the broadest product  lines in the healthcare information systems
industry serving patient care,  clinical, financial and strategic  applications.
Through  its Pathways 2000 family  of patient-focused enterprisewide information
systems, HBOC  facilitates  the  more  efficient  integration  of  IHDS.  HBOC's
Pathways  2000  client  server applications  are  designed to  provide  a common
information infrastructure,  enabling IHDS  to collect,  manage and  disseminate
clinically  oriented information  organized on the  basis of  a patient's entire
history of care.  The Pathways product  line provides the  capability to  create
longitudinal  computerized  patient records  as well  as connectivity  along the
entire continuum of care, enabling users  to access patient data from any  point
within an integrated delivery system.

    PROVIDE  SUPERIOR INTEGRATION OF  PRODUCTS AND DATA.   HBOC's products offer
customers  open  systems  solutions  with  flexibility  in  adding   incremental
capabilities,  which protects  the customers' capital  investments. In addition,
HBOC's client-server  architecture  facilitates  integration  of  clinical  with
financial  and administrative data from both  HBOC and non-HBOC applications for
efficient resource allocation  thereby allowing  its customers  to benefit  from
price/performance  advances. HBOC  believes that these  features will  be of key
significance to healthcare organizations as they face industry consolidation and
evolve as part of integrated delivery systems.

                                       50
<PAGE>
    EXPAND INTO  NEW  MARKETS.    HBOC  strives  to  establish  premier  product
brand-name   recognition  in   new  markets   that  provide   business  critical
applications in every  essential care  setting and the  payer marketplace.  HBOC
believes  that as the healthcare  industry decentralizes, management information
requirements at  the point-of-care  will  increase. HBOC  is developing  or  has
acquired  client  server applications  to meet  these  needs in  the physician's
office, home health market, reference lab and the payer market, all of which are
scheduled to be available in 1995 or early 1996.

    CONTINUE PRODUCT DEVELOPMENT.  HBOC believes that a key to implementing each
of its growth  strategies is  an ongoing focus  on research  and development  to
ensure  its product offerings  will continue to  meet the evolving  needs of its
existing  and  potential  customer  base.  HBOC's  research  efforts  focus   on
enhancements  of existing product offerings as  well as new product development.
In developing its products, HBOC's strategy is to ensure its information systems
are highly  flexible, quickly  adaptable and  can serve  the information  access
needs  of the increasingly  broad range of users.  HBOC's product developers use
state-of-the-art application  development  tools  such  as  program  generators,
artificial  intelligence and expert systems  which decrease development time and
lower the cost of new products. While HBOC's efforts focus primarily on internal
research and development of new products, HBOC has made and continues to explore
strategic acquisitions of developers of niche product software to complement and
diversify its product portfolio.

RECENT ACQUISITIONS

    A substantial portion of HBOC's recent growth has resulted from acquisitions
of companies which expanded  the HBOC product lines  and enhanced its  installed
customer base.

PRODUCT SUMMARY

    HBOC's  offering of  products and  services is based  on a  strategic mix of
applications and technologies that support  the restructuring of the  healthcare
delivery  system, backed  by implementation,  support and  outsourcing services.
This portfolio  of products  is organized  into four  areas: core  applications,
infrastructure   applications,   enterprisewide  clinical   practice  management
applications and enterprise management applications.

    CORE APPLICATIONS automate the operation of individual departments and their
respective functions within the healthcare enterprise.

    INFRASTRUCTURE APPLICATIONS  are  not  limited to  a  single  department  or
function;   rather,  they  form  the  foundation  of  the  emerging  information
structures of healthcare enterprises. Specific components include:

        - Interface managers  that  coordinate the  flow  of  information
          throughout  the greater system and allow disparate incompatible
          source systems  to  communicate with  one  another as  well  as
          enterprise applications;

        - Indexing   applications  that  organize  the  vast  information
          collected about  a  person  throughout the  enterprise  into  a
          patient-centered  index;  allowing  the patient  to  be tracked
          throughout the IHDS; and

        - Data  repository   applications  that   collect  all   of   the
          information  generated  by  source  systems  and  organized  by
          interface managers and patient indexes into central  relational
          databases,  thus forming  the basis for  the electronic medical
          record.

    ENTERPRISEWIDE CLINICAL  PRACTICE  MANAGEMENT  APPLICATIONS  facilitate  and
improve  the  actual practice  of medicine  throughout the  enterprise. Examples
include:

        - Point-of-care workstations  that give  professionals  immediate
          access  to the critical information necessary to provide better
          quality care;

        - Applications that  make use  of patient  information to  create
          protocols and care pathways; and

        - Applications  that  instantly  register  and  schedule patients
          anywhere in  the  enterprise from  any  other point  within  an
          enterprise.

    ENTERPRISE MANAGEMENT APPLICATIONS facilitate and improve the management and
operation  of  healthcare  enterprises. These  applications  focus  on providing
caregivers with  the clinical,  financial, and  other information  necessary  to
improve the operation of the enterprise. Examples include utilization review and
accounts  receivable management, as well as  managed care contracting and member
management applications.

SERVICES

    Installation  and implementation services are provided for purchasers of all
HBOC software products to assist with  the smooth introduction of or  transition
to  those  products. HBOC  also  provides software  maintenance  and enhancement
services, as well as custom programming and system modifications to meet special
client requirements. Equipment maintenance services are provided through  HBOC's
various hardware partners.

    CONNECT  TECHNOLOGY.   To support  the connectivity  needs of  hospitals and
their affiliates, the  Connect Technology Group  ("CTG") provides total  network
installation  and  support. In  addition,  CTG offers  comprehensive value-added
network information services  that extend local  and metropolitan area  networks
outside  of the hospital to include  payers, vendors, financial institutions and
the Internet. All together, HBOC's networking solutions provide customers with a
complete  network  solution   for  electronic  access   throughout  a   provider
enterprise.

    OUTSOURCING  SERVICES GROUP.   HBOC has been in  the outsourcing business in
the United States for more than 20 years and now offers outsourcing services  in
the  United  Kingdom as  well.  With the  change  and uncertainty  engendered by
healthcare reform  and the  resulting  economic pressures,  information  systems
outsourcing  is becoming increasingly popular  in the United States. Outsourcing
services go beyond managing  hospital data processing operations  (traditionally
known  as facilities management)  to encompass strategic  management services in
information  systems   planning,   receivables   management,   business   office
administration and major system conversions.

RESEARCH AND DEVELOPMENT AND TECHNOLOGY

    HBOC's  product development effort applies  advanced computer technology and
installation methodologies to the specific  information processing needs of  its
customers. HBOC believes a substantial and sustained commitment to such research
and development is important to the long-term success of the business.

    Many  of HBOC's products are portable to  a variety of hardware platforms to
protect a  healthcare  organization's  hardware investments  and  enable  it  to
benefit  from price/performance advances. For example,  HBOC offers a full range
of its products on RISC (Reduced  Instruction Set Computing) hardware using  the
UNIX   operating   system,   which   has   very   attractive   price/performance
characteristics.  Additionally,  workstation   technology,  via  PCs,   provides
enhanced  productivity  and appeal  for system  users by  giving them  access to
graphics,  image  processing,  voice   processing,  multiple  technologies   and
sophisticated user interfaces.

    HBOC also offers specialized processors, utilizing client/server technology,
which  provide  organizations with  improved  processing and  storage  for large
volumes of  data  and  specific applications,  including  imaging  and  document
processing.  HBOC utilizes local, metropolitan and wide area networks to provide
faster and more  effective pathways  to distribute  the wider  variety of  data,
images   and  recorded  voice  needed  by  image  processing  and  client/server
applications.

    Investment in software development, including both research and  development
expense as well as capitalized software, has increased as HBOC has addressed new
software  applications and enhanced existing  products for installed systems. In
each of the last three  fiscal years, HBOC expensed  9% of revenue for  research

INDUSTRY BACKGROUND

    The healthcare industry is subject to rapidly changing political, regulatory
and market driven  pressures to contain  healthcare costs. Healthcare  providers
must  demonstrate  not  only that  patients  are  being cared  for  in  the most
cost-efficient setting, but also that each patient's treatment regimen  utilizes
clinical  resources  efficiently  to  produce  the  desired  clinical  outcomes.
Moreover, in  response to  the  growing influence  of managed  care,  healthcare
providers  are increasingly being required to  share or assume the economic risk
of healthcare delivery.  Healthcare providers  must focus not  only on  treating
illness  in a  cost-effective manner  but also  on maintaining  wellness through
preventive care. In response to these dynamics, many providers are consolidating
to take advantage of economics of  scale and operating efficiencies in order  to
become  more  cost-efficient and  are  forming vertically  integrated healthcare
delivery networks to more effectively manage the continuum of patient care.

   
    In response  to  market and  economic  pressures, healthcare  providers  are
requiring  increasingly sophisticated information systems  that can serve larger
and more diverse patient populations,  provide better access to and  integration
of  clinical  information, improve  operating  efficiencies, measure  and report
patient outcomes  and provide  more complete  information regarding  the  actual
costs  of  delivering  and  managing  care.  Traditional  healthcare information
systems  are  limited  in  their  ability  to  automate  patient-care  processes
throughout  a healthcare  delivery network  and in their  ability to  adapt to a
variety of care delivery settings. These limitations stem from inflexible system
architectures  and,  more  importantly,  from  a  focus  on  administrative  and
financial   applications  rather  than  on  clinical  and  patient-care  process
applications, which are necessary to  address the changing clinical  information
needs of healthcare providers today.
    

STRATEGY

   
    CliniCom's  strategy for  operating as  a stand-alone  company addresses the
changing clinical information needs of healthcare organizations and responds  to
the  shift toward integrated delivery networks  by providing system solutions to
manage the  costs  and quality  of  care.  This strategy  includes  the  ongoing
development of software applications which provide an infrastructure for patient
care  management to support the entire continuum of care and enable providers to
develop an integrated computerized patient medical record.
    

                                       56
<PAGE>
   
    CliniCom's strategy is based upon the following factors:
    

    TEN YEARS OF SOLUTION-ORIENTED PRODUCT DEVELOPMENT.  CliniCom has ten  years
of experience in developing patient-focused clinical software applications. This
experience  provides a strong foundation for development of new products and the
enhancement  of  current  product  offerings.  CliniCom,  in  partnership   with
healthcare  providers, works directly with  clinicians to develop products which
meet the clinical information  needs of its  clients. The software  applications
and  enhancements are designed  to be flexible  with representation formats that
are easily modified to meet client standards and user requirements.

    ENABLING   SOFTWARE    TECHNOLOGY    FOR    COST-EFFECTIVE    AND    QUALITY
CARE.    CliniCom's software  products  provide tools  for  evaluation, outcomes
measurement, orders assessment and variance analysis, all of which assist in the
effective management  of patient  care and  healthcare costs.  Applications  are
designed so that information is available on a real-time basis and providers can
manage care efficiently at the time care is being delivered. Furthermore, use of
CliniCom's   system  reduces  time  spent   recording  patient  information  and
eliminates redundant  documentation, which  decreases  overall costs  for  nurse
staffing,  overtime  and  temporary hiring.  CliniCom  applications  improve and
standardize care planning, provide more rapid and accurate treatment  decisions,
improve  compliance  with physician  orders and  allow  multiple user  access to
patient information.

    COMMITMENT TO  OPEN  SYSTEMS  ARCHITECTURE AND  INTEGRATION.    CliniCom  is
committed  to an open  systems architecture, allowing  clinical information from
all areas of a  healthcare network to be  collected, accessed and analyzed  from
all  locations, thereby  reducing redundant data  entry and  providing access to
current patient  information. CliniCom  products incorporate  industry  standard
technologies,  including  the UNIX  operating  system, the  TCP/IP communication
protocol, a relational database management system, the OSF Motif Graphical  User
Interface  and  Microsoft Windows.  This enables  CliniCom to  incorporate third
party products into the CliniCom  system, increases flexibility and permits  the
storage of discreet data.

    PORTABLE  AND WIRELESS PRODUCTS.   The portable CliniView  PC and WIN enable
healthcare providers  to access  and update  information on-line.  The  system's
portability  allows  healthcare  organizations  to  respond  efficiently  to the
changing nature  and  location of  patients  within the  organization.  The  WIN
technology  provides cost savings and allows for easier installation compared to
hardwired  systems  and  enables  hundreds  of  portable  terminals  to  operate
simultaneously within a facility.

    HIGH  QUALITY  CLIENT SERVICE  AND  SUPPORT.   CliniCom  believes it  has an
excellent reputation  for providing  high quality  client service  and  support.
CliniCom provides a toll-free, 24-hour, seven-day-a-week hotline, offers ongoing
education programs and organizes user group meetings. CliniCom's ability to rely
on   its  installed  customer  base   as  reference  sites  establishes  product
credibility and is an integral part of product sales.

   
    CliniCom's long-term growth strategy has been to be the leading provider  of
clinical  information  systems by  offering  a comprehensive,  integrated system
solution for inpatient, home health,  physician clinic, ambulatory and  subacute
settings,  as well as for the  emerging healthcare delivery networks. CliniCom's
growth strategy is comprised  of the following key  elements: (i) continuing  to
develop  and offer  products with  increased functionality;  (ii) broadening its
target markets beyond the hospital;  (iii) leveraging its customer base  through
increased  direct  and  partner  system  sales;  and  (iv)  pursuing  additional
strategic partnerships and acquisitions.
    

TARGET MARKET

    Currently,  CliniCom's  primary  market  consists  of  approximately   5,300
hospitals in the United States (excluding psychiatric hospitals), 2,000 of which
represent  hospitals with 200 or more beds. The nature of the hospital market is
changing as the pressures of managed care, capitation and increasing competition
are forcing  many healthcare  providers to  align and  form integrated  delivery
networks.  Many of  CliniCom's hospital customers  are aggressively establishing
regional  healthcare  networks   by  merging  with   other  hospitals,   forming
primary-care networks and acquiring physician group practices

                                       57
<PAGE>
within  local and  regional markets.  CliniCom believes  that such consolidation
will increase the need for information systems that operate in a common  systems
environment  and integrate patient care processes throughout healthcare delivery
systems. CliniCom also continues to develop new product applications to reach  a
broader  client  base including  home health,  managed care,  physician clinics,
ambulatory and subacute settings.

PRODUCTS

    The CliniCom system is an integrated software/hardware solution based on the
HealthBasys architecture, an  information framework for  managing patient  care,
which  includes the ability to develop standard clinical guidelines for improved
resource  utilization  and  patient   outcomes  and  to  develop   comprehensive
computerized  medical records. The  system provides access  to detailed clinical
information through an  open-systems architecture, a  relational database and  a
wireless  network which allows  on-line access to  patient care information. The
system is designed to enhance the  efficiency of an entire healthcare system  by
unifying clinical information from all areas with a consistent user interface.

SOFTWARE

    CliniCom's  software applications assist  healthcare providers in assessing,
documenting, planning and managing each patient's condition and care. CliniCom's
modular software allows healthcare organizations  to purchase a base system  and
to  add software modules  as their requirements  change and as  new products are
released. CliniCom's  software  products  are functionally  integrated  to  give

APPLICATIONS FOR MANAGING PATIENT CARE

    COORDINATED   CARE.    CliniCom's  coordinated   care  applications  are  an
integrated set  of applications  that allow  for the  coordination of  treatment
planning and implementation, evaluation of patient care information and outcomes
management.  The Guidelines  Manager application is  designed for  both case and
critical pathway  management  and  enables  a  healthcare  provider  to  develop
clinical  guidelines  tailored to  specific  needs. The  Clinical Communications
application   is   a   multi-disciplinary   treatment   management   and   order
communications tool. Physician orders become part of the clinical guidelines and
order results are assessed along with the outcomes of the care plan. Coordinated
care  provides an objective ability to  automatically capture variances from the
established guidelines.

    ASSESSMENT.   These  applications facilitate  the  ongoing assessment  of  a
patient's  condition  from  admission  history through  discharge.  Data  can be
presented in  a  narrative or  flowsheet  format and  displayed  graphically  or
textually  either on-line or in reports. The user can define or modify the input
screens and reports on site.

    CARE PLANNING.  Care planning  applications allow care providers to  create,
revise  and evaluate the plan of care for each patient. These applications allow
each hospital to devise a standard plan of care or create a unique care plan for
each patient. These applications also support a variety of charting methods. The
patient's plan of care can be  accessed by any healthcare provider (with  proper
security  clearance), resulting  in a  comprehensive, multidisciplinary  plan of
care.

    IMPLEMENTATION.  These  applications enable care  providers to document  the
implementation  of  a plan  of  care and  include  (i) the  charting  of patient
treatments and the response to such treatments, (ii) a medication administration
system utilizing bar codes to identify the patient and providers and to  confirm
the  medication  to  be  administered  (providing  reminders  and  alerts  where
appropriate), (iii) an  IV medicated  drip module which  calculates dosages  and
rates automatically and (iv) the ability to acquire data from patient monitors.

    EVALUATION.   Evaluation  applications allow  care providers  to compare the
plan of care  with the  actual care  provided and  to manage  patient care.  The
screen  display  can  be configured  for  specialty groups  such  as cardiology,
urology and respiratory. Data can be displayed graphically or textually  on-line
in review systems or reports. A flowsheet format is generally used to facilitate
viewing of trends and correlation of patient data.

    SPECIFIC  CARE AREAS.  CliniCom also provides applications for specific care
areas  including  critical  care,   medical/surgical  care,  obstetrical   care,
pediatric  care and respiratory  care. Each application is  designed to meet the
unique requirements of all phases of  care and each specific application may  be
integrated  with the others. CliniCom's  home health product, Charisma, contains
applications which support  infusion therapy, pharmacy,  home medical  equipment
and  respiratory care. The Charisma system addresses patient management, managed
care pricing, document tracking,  inventory, outcomes and utilization  reporting
and electronic claims processing and reimbursement.

    SYSTEM  ADMINISTRATION.    System  administration  and  integration software
includes  system  administration  functions  and  allows  hospitals  to  control
security,  report  requests  and  formats.  The screen  system  can  be  used by
hospitals  to  customize  screen   displays  without  changing  the   underlying
application.  New  screens can  be  quickly and  easily  created on-site  by the
hospital as technology,  procedures and documentation  requirements change.  The
system  integration  software allows  the provider  to combine  information from
various sources into a single flowsheet presentation.

    DECISION SUPPORT.  CliniCom's decision support application, Clinical  Query,
is  an intuitive, user-friendly decision support tool that allows clinicians and
healthcare management  personnel  to  extract and  organize  clinical  data  for
on-line  review  and analysis.  Reports  generated from  Clinical  Query display
information in user-defined formats, including detailed graphics and charts, and
provide a  comprehensive,  clear  summary of  information  to  enhance  decision
making.

                                       60
<PAGE>
    COMMUNICATIONS.   CliniCom's  Carelink 7  is a  comprehensive communications
application designed to complement and integrate disparate information  systems,
information generated by medical devices and personal communication systems used
in  healthcare organizations. It is comprised  of various modules that translate
various communication protocols, support the automatic acquisition of data  from
medical  monitors  and  communicate information  on  network-based  systems. The
applications  are  functionally  integrated  to  support  the  clinical  process
regardless of care delivery location.

PATIENT CARE DATABASE

    CliniCom  currently utilizes a relational database management system for the
collection and integration of clinical information into a central database.  The
integration  of patient  information in  a relational  database allows  users to
access patient information from a variety of sources.

WIRELESS INTERACTIVE NETWORK

    CliniCom has developed  and patented a  wireless interactive network  (WIN),
designed  to  enable portable  terminals or  PCs and  other hardware  devices to
communicate on-line with the host server system without physical wiring. The WIN
utilizes spread spectrum, frequency hopping and data encryption technologies  to
ensure  the integrity of  data transmissions. The  WIN technology provides costs
savings and easier installation over  hardwired systems and enables hundreds  of
portable terminals to operate simultaneously within a facility.

THIRD PARTY HARDWARE AND SOFTWARE

    CliniCom  purchases third party hardware  and software which it incorporates
into the  CliniCom  system.  The  CliniCom  system  utilizes  industry  standard
components  such  as  the  ORACLE relational  database,  UNIX  operating system,
Ethernet network communications medium,  TCP/IP communication protocols and  the
ANSI-C  and Cognos'  POWERHOUSE programming  language. The  CliniCom system also
operates  on   multiple   computing  platforms   such   as  the   IBM   RS-6000,
Hewlett-Packard, Data General and Sequent Symmetry products. By utilizing "open"
hardware  options that meet industry standards, CliniCom offers clients a choice
of terminals. CliniCom's CliniView PC product allows for a similar  presentation
format  on a variety of terminals, from portable terminals to desktop computers.
CliniCom is currently marketing and installing the following terminals:

        CLINIVIEW PC:  A portable, pen-based computer that communicates  on-line
        via  the  WIN technology  and includes  an  optional barcode  reader for
        disposables,  medication  and  provider  identification.  CliniCom   has
        designed  a handle which  incorporates a radio  and wall mounted charger
        for  the  computer.  The  CliniView  PC  terminal  replaces   CliniCom's
        CliniView RF terminal.

        OTHER  TERMINALS:   X Window  terminals, manufactured  by other vendors,
        provide color and high  resolution graphics and  are offered along  with
        other  third-party terminals  and personal computers  that are Microsoft

NEW PRODUCT DEVELOPMENT

   
    CliniCom has made a significant  investment in research and development  and
continues  to expand the CliniCom system. CliniCom's product development efforts
are focused  on  the  completion of  CliniCom's  HealthBasys  architecture,  the
infrastructure  designed  to assist  healthcare providers  in the  management of
patient populations. CliniCom's  long-term product development  objective is  to
enable  healthcare organizations to  maintain a computerized  medical record for
all patient information  recorded and used  during each phase  of patient  care,
including  inpatient,  outpatient  and long  term/home  healthcare.  A strategic
element of  this objective  is  the ongoing  development  of the  LifeBase  data
repository.   CliniCom   is   currently   developing   the   following  software
applications:
    

        LIFEBASE:  A comprehensive database that integrates clinical, financial,
        cost,  administrative  and  demographic   information  into  a   central
        database.  This repository is  the enabling technology  for managing the
        information requirements  of  a  healthcare delivery  network  and  will
        contain  all of the clinical information  pertinent to a patient's case,
        including standards  of care,  a record  of patient  care variances,  an
        account  of  all scheduled  and actual  resources, a  long-term clinical
        profile and the computer-based patient record.

        COMMUNITY PATIENT INDEX AND REGISTRATION:  A patient identification  and
        tracking   tool  which  will  provide  a  healthcare  organization  with
        important information about  each patient's health  status and  previous
        healthcare  system encounters, as well  as demographic, employer, family
        and insurance information.

        CLINICAL PROFILE:  An intelligent, clinician-defined summary of relevant
        information from  the  patient  care database  that  includes  only  the
        specific  data the  clinician requires  to make  efficient and effective
        decisions.

        CLINICAL ENCOUNTER:   Several modular applications  designed to  support
        the  physician,  whether  in an  ambulatory  or acute  care  setting, in
        assessing and  diagnosing a  patient, developing  a treatment  plan  and
        documenting  the patient's progress. This information will become a part
        of the  continuum-based clinical  record in  the LifeBase  patient  care
        database.

        HEALTHVIEW:  A user-friendly graphical information tool that will enable
        clinicians   to  review  and  act  upon   patient  data  from  a  single
        application, eliminating the need to access multiple systems.

    In addition,  CliniCom intends  to expand  its Coordinated  Care product  to
include Order Management, which will communicate orders to ancillary systems and
departments  by  electronic messages  and/or paper-based  requisitions. CliniCom
also plans  to  extend Guidelines  Manager,  Clinical Communications  and  Order
Management  to  manage care  delivered in  an  outpatient setting.  In addition,
CliniCom may  seek  to acquire  additional  products or  develop  joint  venture
relationships.  There  can  be  no assurance,  however,  that  CliniCom  will be
successful in developing or acquiring such application software.

    In addition to the development  of new software applications, CliniCom  will
continue to enhance the WIN. CliniCom will also review new product introductions
by  other manufacturers in the area of hardware technology and will evaluate the
adoption of such new technology into its product line where appropriate.

SALES AND MARKETING

    CliniCom sells and markets its  products through a twenty-five person  sales
force.  The sales effort is  supported by a sales  support group and a marketing
communications program  designed to  achieve frequent  contact with  the  target
market.  The program includes  advertising, trade show  participation, a program
for industry consultants, quarterly newsletters, public relations activities and
a direct marketing effort.

    Under customary  sales  arrangements,  CliniCom agrees  to  deliver  to  its
clients both the hardware and software necessary to operate the CliniCom system.
CliniCom licenses software to its clients in

                                       62
<PAGE>
perpetuity  on  a  non-exclusive  and  non-transferable  basis.  Because  of the
relatively high  price  of a  new  system, healthcare  organization  procurement
cycles  for these products  have typically required  multiple approvals and have
often spanned six to  eighteen months. In  many cases, healthcare  organizations
employ  consultants to assist them in  assessing alternative systems and issuing
requests for proposals from vendors.

    CliniCom is an industry remarketer  for Oracle Systems Corporation,  Cognos,
IBM,  Hewlett-Packard  Company,  Toshiba,  Data  General  and  Sequent  Computer
Systems, each of whose products may be  used as part of the CliniCom system.  In
addition,  certain of these manufacturers provide additional sales and marketing
exposure for the CliniCom system through cooperative marketing programs,  direct
sales assistance and seminars jointly sponsored with CliniCom.

HBOC AGREEMENT

    In  December  of  1993,  CliniCom  entered into  the  HBOC  Agreement  for a
three-year term, expiring December 31, 1996, unless renewed. The HBOC  Agreement
grants  HBOC  a  non-exclusive,  non-transferable license  to  use  the CliniCom
software (i) to sublicense  to new and existing  customers, (ii) to develop  and
enhance  interfaces  with  HBOC's software  and  (iii) to  provide  training and
technical support. The HBOC  Agreement grants HBOC the  right to sublicense  the
software  modules only as an integrated  component of HBOC's product lines. HBOC
is prohibited from marketing the software as a stand-alone system or as a system
interfacing with a non-HBOC system. HBOC  is also prohibited from licensing  any
application  or system  software from or  to third parties  that are competitive
with CliniCom's  software,  including  software developed  by  HBOC.  Similarly,
CliniCom is prohibited from entering into similar distribution arrangements with
vendors  whose  principal  business  is the  development  and  sale  of hospital
information systems. Under the HBOC Agreement, HBOC pays CliniCom  approximately
50%  of revenues generated from CliniCom  software sales. HBOC and CliniCom have
also entered into agreements under which CliniCom provides hardware installation
and software support. For the years ended December 31, 1993 and 1994 and for the
six months ended June 30, 1995, CliniCom derived 19%, 29% and 54%, respectively,
of its total  sales from its  cooperative marketing arrangement  with HBOC.  The
HBOC Agreement may be terminated by HBOC only for a material breach.

    The  foregoing is  a summary  description of  the business  of CliniCom. For
further information, see "Incorporation of Certain Information By Reference."

                             CERTAIN LEGAL MATTERS

    The validity  of the  shares of  HBOC Common  Stock offered  hereby will  be

                                    EXPERTS

    The  audited financial statements of HBOC  incorporated by reference in this
Proxy Statement/ Prospectus and elsewhere in the Registration Statement of which
this Proxy Statement/Prospectus  is a part,  to the extent  and for the  periods
indicated in their report, have been audited by Arthur Andersen LLP, independent
public  accountants, and are  included herein in reliance  upon the authority of
said firm as experts in giving said reports.

    With respect to the unaudited interim financial information of HBOC for  the
quarter ended March 31, 1994 and 1995, and the quarter and six months ended June
30,  1994  and 1995,  which are  also incorporated  by reference  herein, Arthur
Andersen LLP  has applied  limited procedures  in accordance  with  professional
standards  for a  review of  that information.  However, their  separate reports
thereon state that they did not audit and they do not express an opinion on that
interim financial  information. Accordingly,  the degree  of reliance  on  their
reports  on that information should be restricted in light of the limited nature
of the review procedures applied. In  addition, the accountants are not  subject
to the liability provisions of Section 11 of the Securities Act for their report
on  the unaudited  interim financial  information because  that report  is not a
"report" or a "part" of the Registration Statement prepared or certified by  the
accountants within the meaning of Sections 7 and 11 of the Securities Act.

    The  audited financial statements  and schedule of  CliniCom incorporated by
reference in this Proxy Statement/Prospectus  and elsewhere in the  Registration
Statement  of which this Proxy Statement/Prospectus is a part, to the extent and
for the periods indicated in their reports, have been audited by Arthur Andersen
LLP, independent  public accountants,  and  are included  in reliance  upon  the
authority of said firm as experts in giving said reports.

    The  financial statements of HSG at December 31, 1993 and 1994, and for each
of the three years in the period ended December 31, 1994 incorporated herein and
in the Registration Statement of which this Proxy Statement/Prospectus is a part
have been audited by Ernst  & Young LLP, independent  auditors, as set forth  in
their reports thereon, and are incorporated herein in reliance upon such reports
given upon the authority of such firm as experts in accounting and auditing.

distribution of Parent shall relate to  any such fractional share interest,  and
no  such fractional share interest shall entitle the owner thereof to vote or to
any other rights  of a stockholder  of Parent.  In lieu of  any such  fractional
share, any holder of Acquired Company Stock shall be entitled, upon surrender in
accordance  herewith of  such holder's certificate  or certificates representing
Acquired Company Stock, to receive a cash payment therefor, without interest, at
a PRO RATA amount based  on a per share amount  equal to the Pre-Closing  Parent
Stock  Price. No  interest shall accrue  with respect  to any cash  held for the
benefit of holders of unsurrendered certificates theretofore representing shares
of Acquired Company Stock at the Effective Time.

    (e) All shares  of Parent Stock  into which shares  of the Acquired  Company
Stock have been converted pursuant to this Section 2.1.6 shall be deemed to have
been  issued in  full satisfaction  of all  rights pertaining  to such converted
shares and shall, when issued pursuant  to the provisions hereof, be fully  paid
and nonassessable.

    (f)  The stock transfer books of the Acquired Company shall be closed at the
Effective Time, and  thereafter no transfer  of any shares  of Acquired  Company
Stock  shall be recorded thereon. In the event a transfer of ownership of shares
of Acquired Company Stock  is not recorded  on the stock  transfer books of  the
Acquired Company, a certificate or certificates representing the number of whole
shares  of the  Parent Stock  into which such  shares of  Acquired Company Stock
shall have been converted  in connection with  the Merger may  be issued to  the
transferee  of  such shares  of  Acquired Company  Stock  if the  certificate or
certificates representing  such  shares of  Acquired  Company Stock  is  or  are
surrendered  to the Exchange Agent accompanied by all documents deemed necessary
by the  Exchange Agent  to evidence  and effect  such transfer  of ownership  of
shares of Acquired Company

                                      A-4
<PAGE>
Stock  and by the payment  of any applicable stock  transfer tax with respect to
such transfer,  subject  to  compliance  with  any  restrictions  or  conditions
contained  herein with  respect to  the transfer  of shares  of Acquired Company
Stock.

    (g) In the event that Parent at any time or from time to time after the date
of this Agreement,  but prior to  the Effective Time,  effects a subdivision  or
combination  of the outstanding Parent Stock into  a greater or lesser number of
shares, then and  in each  such event the  Exchange Ratio  described in  Section
2.1.6(a)  shall be  increased or  decreased proportionately.  In the  event that
Parent at any time or  from time to time shall  fix a record date, which  record
date  is after the date  of this Agreement but prior  to the Effective Time, for
the determination of holders of Parent  Stock entitled to receive a dividend  or
other  distribution payable in  additional shares of  Parent Stock, cash (except
Parent's regular quarterly dividend),  or any other property,  then and in  each
such  event, regardless of whether such dividend is to be paid prior to or after
the Effective  Time, the  Merger Consideration  payable hereunder  per share  of
Acquired   Company  Stock  shall  be  increased  to  reflect  such  dividend  or
distribution as though each stockholder of the Acquired Company were, as of such
issuance or record date, a holder of  record of that number of shares of  Parent
Stock  comprising the Merger Consideration otherwise payable to such stockholder
pursuant to Section 2.1.6(a).

    2.1.7.   STOCK OPTIONS.    Options granted  under  the Stock  Option  Plans,
regardless  of whether such options are  currently exercisable, shall be treated
as follows:

        (a) At the Effective  Time, Parent shall  assume the Acquired  Company's
    rights  and  obligations under  each of  the outstanding  options previously
    granted under the Director Stock Option  Plan and the Employee Stock  Option
    Plan  (each such  option existing  immediately prior  to the  Effective Time
    being called an "Existing Option," and each such option so assumed by Parent
    being called an "Assumed  Option"), by which  assumption the optionee  shall
    have  the right to purchase  that number of shares  of Parent Stock (rounded
    down to  the nearest  whole) into  which the  number of  shares of  Acquired
    Company   Stock   the  optionee   was   entitled  to   purchase   under  the
    Existing Option  would have  been converted  pursuant to  the terms  of  the
    Merger  as  described in  Section 2.1.6  hereof.  Each Assumed  Option shall
    constitute a continuation  of the Existing  Option, substituting Parent  for
    Acquired  Company as  issuer and employment  by Parent, Purchaser  or one of
    their respective subsidiaries  for employment by  the Acquired Company.  The
    aggregate  price for the total number of shares of Parent Stock at which the
    Assumed Option may be  exercised shall be the  aggregate price at which  the
    Existing  Option was exercisable for the  total number of shares of Acquired
    Company Stock, reduced (as necessary for  purposes of rounding down) to  the
    price  that will buy the number of whole shares for which the Assumed Option
    will be exercisable in accordance with this paragraph (a), and the  purchase
    price  per share  of Parent Stock  thereunder shall be  such aggregate price
    divided by the total number of shares of Parent Stock covered thereby.

        (b) Each participant  in the  Employee Stock  Purchase Plan  on the  day
    prior to the Effective Date shall receive (1) the number of shares of Parent
    Stock  into  which the  shares of  Acquired Company  Stock issuable  to such
    participant in accordance with the  Employee Stock Purchase Plan would  have
    been converted and (2) cash in lieu of any fractional share of Parent Stock,
    together with a cash refund of any excess of the amount collected during the
    purchase  period,  over the  amount of  the purchase  price of  the Acquired
    Company Stock that otherwise would be issuable to such participant.

    2.1.8.  STOCKHOLDERS'  MEETING.   The Acquired Company,  acting through  its
Board of Directors, shall:

        (a)  promptly furnish a copy  of the proxy statement/prospectus included
    in the Registration Statement  (defined in Section 2.3.1  below) to each  of
    its  stockholders after the Registration Statement has become effective with
    the SEC;

                                      A-5
<PAGE>
        (b) duly call, give notice of, convene and hold a special meeting of its
    stockholders  and  submit  this  Agreement  and  any  related  matters,   as
    appropriate, and the Merger to a vote of the Acquired Company's stockholders
    as soon as practicable for the purpose of considering and taking action upon
    this Agreement and any such related matters; and

        (c)  use  its  reasonable best  efforts,  subject to  the  provisions of
    Section 2.11,  to  obtain  the  necessary approval  of  the  Merger  by  its
    stockholders.

    2.1.9.    CLOSING; FILING  OF CERTIFICATE  OF  MERGER.   Upon the  terms and
subject  to  the  conditions  hereof,  as  soon  as  practicable  following  the
satisfaction  or waiver of  the conditions set  forth in Articles  V, VI and VII
hereof,  the  Acquired  Company  and  Purchaser  shall  execute  and  file   the
Certificate of Merger referred to in Section 2.1.2 in the manner required by the
Delaware  Code, and  the parties  hereto shall take  all such  other and further
actions as may be  required by law  to make the Merger  effective. Prior to  the
filing referred to in this Section 2.1.9, a closing (the "Closing") will be held
as  set forth in  Section 8.1 hereof, for  the purpose of  confirming all of the
foregoing.

    2.2  DELIVERY OF MERGER CONSIDERATION.

    2.2.1.   EXCHANGE AGENT.    Prior to  the  Effective Time,  Purchaser  shall
designate  a bank or trust  company to act as  Exchange Agent in connection with
the Merger (the "Exchange  Agent"). At the Effective  Time, Purchaser or  Parent
shall  take all  steps necessary  to enable  and cause  Parent or  the Surviving
Corporation to provide the  Exchange Agent with the  shares of Parent Stock  and
cash   in  respect  of  fractional  shares   necessary  to  deliver  the  Merger
Consideration to  each  holder of  Acquired  Company Stock  as  contemplated  by
Section  2.1.6 hereof prior to the time  that such deliveries are required to be
made by the Exchange Agent as provided in this Section 2.2.

    2.2.2.       SURRENDER   OF    CERTIFICATES   AND    DELIVERY   OF    MERGER
CONSIDERATION.  Promptly after the Effective Time, the Exchange Agent shall mail
to  each record holder (as of the  Effective Time) of an outstanding certificate
or certificates  that  immediately  prior  to  the  Effective  Time  represented
outstanding  shares of Acquired Company Stock  (the "Certificates"), a letter of
transmittal in customary form (which specifies that delivery shall be  effected,
and  risk of  loss and title  to the  Certificates shall pass,  only upon proper
delivery of the Certificates to the Exchange Agent) and instructions for use  in
effecting  the  surrender  of  the  Certificates  in  exchange  for  the  Merger
Consideration. Upon surrender to the  Exchange Agent of a Certificate,  together
with  such letter of transmittal properly  completed and duly executed, together
with any  other required  documents, the  holder of  such Certificate  shall  be
entitled  to receive  in exchange  therefor the  Merger Consideration,  and such
Certificate shall forthwith be cancelled. If payment  is to be made to a  Person
other  than the Person in whose  name the Certificate surrendered is registered,
it shall be a condition of payment that the Certificate so surrendered shall  be
properly  endorsed or otherwise in proper form  for transfer and that the Person
requesting such payment shall pay any transfer or other taxes required by reason
of the payment to a Person other  than the registered holder of the  Certificate
surrendered  or establish to the satisfaction  of the Surviving Corporation that
such tax has  been paid or  is not applicable.  Until surrendered in  accordance
with  the provisions of this Section 2.2.2, each Certificate shall represent for
all purposes only  the right to  receive the Merger  Consideration, without  any
interest on the value thereof.

    2.3.3.   ESCHEAT LAWS.  Notwithstanding any  provision of this Article II to
the contrary, neither Parent  nor the Surviving Corporation  shall be liable  to
any  holder  of Certificates  formerly representing  shares of  Acquired Company
Stock for any property  properly delivered or amount  paid to a public  official
pursuant to any applicable abandoned property, escheat or similar law.

    2.3  SEC REGISTRATION.

    2.3.1.   The Acquired Company shall furnish to Parent such information about
the  Acquired  Company,  including  without  limitation  information  about  its
stockholders,  as may be necessary to enable Parent to prepare and file with the
SEC a Registration Statement on Form S-4  under the 1933 Act, and the rules  and
regulations  promulgated thereunder, in respect of the Parent Stock to be issued
by reason of the  Merger (such registration  statement, the prospectus  included
therein and the proxy

                                      A-6
<PAGE>
statement  to be furnished to the holders of the Acquired Company Stock, in each
case together with any amendments thereto,  being referred to in this  Agreement
as  the "Registration Statement"). The  Acquired Company Information (as defined
below) included  in  the Registration  Statement  shall  not, at  the  time  the
Registration  Statement is declared effective, contain any untrue statement of a
material fact or omit to state any  material fact required to be stated  therein
or  necessary in order to make the  statements therein not misleading. If at any
time prior to the Effective  Time any event or  circumstance should come to  the
attention  of  the  Acquired  Company  with  respect  to  the  Acquired  Company
Information that is required to  be set forth in  an amendment or supplement  to
the Registration Statement, the Acquired Company shall immediately notify Parent
and   shall  assist  Parent  in  appropriately  amending  or  supplementing  the
Registration Statement in the  manner contemplated in  Section 2.3.4 below.  The
Registration  Statement  insofar as  it  relates to  information  concerning the
Acquired Company, or its business, assets, directors, officers, or  stockholders
or  other matters  pertaining to  the Acquired Company  that is  supplied by the
Acquired Company  for inclusion  in the  Registration Statement  (the  "Acquired
Company  Information") shall  comply as  to form  and substance  in all material
respects with the  applicable requirements  of the 1933  Act and  the rules  and
regulations  thereunder  and  the Exchange  Act  and the  rules  and regulations
thereunder; except  that  the  Acquired  Company  shall  have  no  liability  or
obligation for any information other than the Acquired Company Information.

    2.3.2.   The Acquired Company shall use its reasonable best efforts to cause
its accountants, Arthur Andersen, LLP, to deliver to Parent letters dated at the
time the Registration Statement  becomes effective and as  of the Closing  Date,
addressed  to Parent, both (i) to the effect that the Acquired Company satisfies
the tests  applicable to  it such  that the  Merger can  be accounted  for as  a
"pooling  of interests";  and (ii)  containing such  matters as  are customarily
contained in auditors' letters regarding information about the Acquired  Company
furnished  expressly for inclusion in the  Registration Statement, and in a form
and substance  reasonably  satisfactory to  Parent.  The Parent  shall  use  its
reasonable  best  efforts  to cause  its  accountants, Arthur  Andersen,  LLP to
deliver to the Acquired  Company letters at  such times to  the effect that  the
Parent  satisfies  the  applicable tests  for  accounting  for the  Merger  as a
"pooling of interests."

    2.3.3.  Parent shall file  and use its reasonable  best efforts to have  the
Registration Statement declared effective by the SEC as promptly as practicable,
and  shall use  its reasonable best  efforts to  take any action  required to be
taken to  comply  with  any  applicable federal  or  state  securities  laws  in
connection  with the issuance  of Parent Stock  in the Merger;  except that such
covenant of Parent is made, as  to those portions of the Registration  Statement
containing  or required  to contain  Acquired Company  Information, assuming and
relying on timely and full compliance with Sections 2.3.1 and 2.3.2.

    2.3.4.  Parent covenants that the  Registration Statement shall not, at  the
time  it is declared effective, contain any  untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements therein  not misleading; except that such  covenant
of Parent is made, as to those portions of the Registration Statement containing
or  required to  contain Acquired Company  Information, assuming  and relying on
timely and full compliance with Sections 2.3.1  and 2.3.2. If at any time  prior
to  the Effective Time any event or circumstance should come to the attention of
Parent that is required  to be set  forth in an amendment  or supplement to  the
Registration Statement, Parent shall use its reasonable best efforts to amend or
supplement  appropriately the Registration Statement. An amendment or supplement
may be accomplished,  to the  extent permitted by  law, rule  or regulation,  by
including  such  information  in  a  filing  under  the  Exchange  Act  that  is
incorporated by reference into the Registration Statement.

    2.3.5.   Parent covenants  that  the Registration  Statement and  all  other
documents  required to be  filed by Parent  with the SEC  in connection with the
transactions contemplated herein shall  comply as to form  and substance in  all
material  respects  with  the  applicable  requirements  of  the  1933  Act  and

                                      A-7
<PAGE>
the rules and  regulations thereunder  and the Exchange  Act and  the rules  and
regulations thereunder; except that Parent shall have no liability or obligation
for  any failure to  comply with such  requirements arising out  of the Acquired
Company Information.

    2.3.6.  Parent shall use all its reasonable best efforts to file all reports
required to be filed by it on a timely basis under the 1933 Act or the  Exchange
Act  and the rules and regulations adopted by the SEC thereunder. Parent and the
Acquired Company shall use  their reasonable best efforts  to take such  further
action  as may be necessary to ensure that the requirements of Rule 144(c) under
the 1933 Act  are satisfied so  as to  enable any "affiliates"  of the  Acquired
Company  (as that term is used in Rule 145  under the 1933 Act) to offer or sell
the Parent Stock received  by them in  the Merger pursuant  to paragraph (d)  of
Rule  145 (subject to compliance with the  provisions of paragraphs (e), (f) and
(g) of Rule 144).

    2.3.7.  Parent shall use its reasonable best efforts to obtain prior to  the
effective  date of the  Registration Statement all  necessary "Blue Sky" permits
and approvals, if any, required to consummate the Merger.

    2.4  AFFILIATES.

    (a) The Acquired Company shall use its reasonable best efforts to cause each
person that is an "affiliate" of  the Acquired Company under the Securities  Act
on  the date  of the  Acquired Company's stockholder  meeting to  deliver to the
Parent at the  Closing a written  agreement substantially in  the form  attached
hereto as EXHIBIT 2.4(A) ("Rule 145 Letters").

    (b) The Acquired Company shall use its reasonable best efforts to cause each
person  that is an "affiliate" of the  Acquired Company under the Securities Act
31 days  prior to  the date  of the  Acquired Company's  stockholder meeting  to
deliver to the Parent on such date a written agreement substantially in the form
attached hereto as EXHIBIT 2.4(B) ("Pooling Letters").

    2.5   TRADING PROHIBITIONS.  The parties hereto hereby acknowledge that as a
result of disclosures by the Acquired Company, Parent and Purchaser contemplated
under this Agreement, each of the parties and their affiliates may, from time to
time, have  material, non-public  information concerning  the Acquired  Company,
Parent, Purchaser and their respective subsidiaries or affiliated companies. The
parties confirm that they and their affiliates are aware, and have advised their
directors,  officers, employees and representatives  that, (i) the United States
securities laws may prohibit a  person who has material, non-public  information
from  purchasing or selling securities of  any company to which such information
relates, and (ii) material non-public  information shall not be communicated  to
any other person except as permitted herein.

    2.6  CONDUCT OF THE BUSINESS OF THE ACQUIRED COMPANY PRIOR TO CLOSING.

    2.6.1.   Except (i)  with the prior  consent in writing  of Purchaser (which
consent may not be unreasonably withheld in respect of subparagraph (e)  below),
(ii)  as  may  be  required  to effect  the  transactions  contemplated  by this
Agreement, or  (iii)  as provided  otherwise  in this  Agreement,  the  Acquired
Company  covenants that,  between the date  of this Agreement  and the Effective
Time, the Acquired Company will conduct its business in the ordinary course, and
that it will:

        (a) preserve the corporate organization  of the Acquired Company  intact
    and  use its reasonable  best efforts to preserve  the goodwill of customers
    and others having business relations with the Acquired Company;

        (b) use its reasonable  best efforts to maintain  the properties of  the
    Acquired  Company in substantially  the same working  order and condition as
    such properties are in as of the date of this Agreement, reasonable wear and
    tear excepted;

        (c) not effect  any sale, assignment  or transfer of  any of its  assets
    except  in the ordinary  course of business  and except for  the transfer of
    funds described on  EXHIBIT 2.6.1(C)  a trust under  the Acquired  Company's
    Executive Retention Plan;

                                      A-8
<PAGE>

    their present  limits  all  existing policies  of  insurance  or  comparable
    replacements thereof insuring the Acquired Company and its properties;

        (e)  not  enter into  or  renew any  Material  Contract, enter  into any
    material amendment to any Material Contract  or suffer, permit or incur  any
    of  the transactions or events described in Section 3.9 hereof to the extent
    such events or transactions are within  the control of the Acquired  Company
    (except  that the Acquired Company may  enter into Customer Contracts in the
    ordinary course of business consistent with historical practices);

        (f) not make or permit any change in the Acquired Company's  Certificate
    of Incorporation or Bylaws, or in its authorized securities;

        (g)  other than  pursuant to  the existing  terms of  the Employee Stock
    Purchase Plan, not grant any stock option or right to purchase any  security
    of   the  Acquired  Company,  issue   any  security  convertible  into  such
    securities, purchase,  redeem,  retire  or otherwise  acquire  any  of  such
    securities, or agree to do any of the foregoing or declare, set aside or pay
    any dividend, make any other distribution or declare any split in respect of
    such securities;

        (h)  not adopt any new Benefit Plan  or amend any existing Benefit Plan,
    and not make any contribution to  or distribution from any employee  benefit
    plan,  pension plan,  stock bonus plan,  401(k) plan or  profit sharing plan
    (except for  the  payment  of  any health,  disability  and  life  insurance
    premiums  that may become due and  except for contributions or distributions
    required to be  made or as  consistently made  in the past  pursuant to  the
    terms of any Benefit Plans);

        (l)  not alter in any manner  not permitted herein the terms, conditions

    which the Acquired Company  becomes aware after the  date of this  Agreement
    that,  if existing or known at the date  hereof, would be required to be set
    forth or described in this Agreement or the Exhibits hereto.

    2.6.2.   Except after  prior notification  to, and  with the  prior  written
consent  of, Purchaser,  which consent shall  not be  unreasonably withheld, the

Effective  Time, any change in its banking or safe deposit arrangements or grant
any powers of attorney.

    2.7  FILING OF  TAX RETURNS.   The Acquired Company shall  cause all of  the
Acquired  Company's material federal, state and local tax returns required to be
timely filed before the  Effective Time to be  timely and accurately filed  with
the  appropriate  taxing authorities.  For purposes  of  this Section  2.7, such
returns shall be  deemed timely filed  if the Acquired  Company has obtained  an
extension  from the appropriate taxing authority as  to the time in which it may
file such tax returns. The Acquired Company shall submit all such tax returns to
Purchaser at least fifteen (15) days prior  to the date they must be filed,  and
Purchaser  shall have the  opportunity to comment on  such returns. The Acquired
Company shall give  reasonable and  due consideration  to any  comments on  such
returns made by Purchaser in light of the circumstances in which they are made.

    2.8  EXAMINATION OF PROPERTY AND RECORDS; CONFIDENTIALITY OF INFORMATION.

    2.8.1.   Between  the date  of this  Agreement and  the Effective  Time, the
Acquired Company shall  allow Purchaser, its  counsel and other  representatives
full  access  to  its  books,  records,  files,  documents,  assets, properties,
contracts and  agreements  as may  be  reasonably requested,  and  the  Acquired
Company  shall furnish  the Purchaser,  its officers  and representatives during
such period with  all information concerning  its affairs as  may be  reasonably
requested.  Between the  date of this  Agreement and the  Effective Time, Parent
shall provide  to the  Acquired Company  such information  about Parent  as  the
executive  officers of the Acquired Company reasonably request in the context of
the transactions provided for herein. All such requests shall be directed to the
Chief Financial Officer of Parent. Each party shall conduct any investigation in
a manner that will not unreasonably  interfere with the businesses of the  other
party.

    2.8.2.   All  non-public information  acquired by  a party  pursuant to this
Section 2.8 or otherwise  in connection with this  Agreement, whether or not  in
writing,  concerning the business, operations and affairs of another party, will
be kept confidential  and will not  be disclosed  to any Person  other than  the
parties  hereto or their authorized representatives (who shall be subject to the
same obligations)  and  will  not  be  used  for  any  purpose  other  than  the
consummation  of  the  Merger  and the  related  transactions  described herein,
provided that any party may,  upon advice of counsel,  and upon prior notice  to
the  party whose information is sought to be disclosed, comply with any order of
any court or governmental body. Promptly upon termination of this Agreement, and
at the request  of a disclosing  party, all written  materials thus obtained  by
another  party or any of its representatives and all copies and extracts of such
materials will be delivered to the disclosing party.

    2.9  CONSENTS AND APPROVALS.  As  and to the extent requested by  Purchaser,
the Acquired Company shall use its reasonable best efforts to obtain the waiver,
consent and approval of all persons (other than customers) whose waiver, consent
or approval (i) is required in order to consummate the transactions contemplated
by  this  Agreement or  (ii) is  required by  any agreement,  lease, instrument,
arrangement, judgment, decree, order or license to which the Acquired Company is
a party or subject on the Effective Time and (a) that would prohibit or  require
the  waiver, consent or approval of any  party to such transactions or (b) under
which, without  such  waiver,  consent  or  approval,  such  transactions  would
constitute  an occurrence of default under the provisions thereof, result in the
acceleration of any obligation thereunder or give  rise to a right of any  party
thereto  to terminate  its obligations thereunder.  The failure  of the Acquired
Party to obtain any such waiver, consent or approval (after using its reasonable
best efforts to do so) shall not constitute a breach of, or default under,  this
Agreement.

    2.10   SUPPLYING OF  FINANCIAL STATEMENTS.  Parent  and the Acquired Company
shall each  deliver to  the other  all  of its  regularly prepared  audited  and
unaudited consolidated and consolidating financial statements prepared after the
date  of this Agreement, in format historically published or utilized internally
(as applicable), and any financial statements prepared for filing with the  SEC,
as soon as each is available.

    2.11   NO SOLICITATION.   The Acquired  Company shall not,  and the Acquired
Company shall not authorize or permit  any officer, director or employee of,  or
any  financial advisor, attorney, accountant  or other advisor or representative
retained by, the Acquired Company to, solicit, initiate, encourage (including by
way of furnishing information), endorse or enter into any agreement with respect
to, or take any other action to  facilitate, any inquiries or the making of  any
proposal  that  constitutes,  or may  reasonably  be  expected to  lead  to, any
Takeover Proposal (as hereafter defined). Neither the Board of Directors of  the
Acquired  Company nor  any committee  thereof shall  (a) withdraw  or modify, or
propose to withdraw or modify, in a manner adverse to Purchaser the approval  or
recommendation  by the Board of Directors of  the Acquired Company of the Merger
or this  Agreement  or  (b) approve  or  recommend,  or propose  to  approve  or
recommend,  any Takeover Proposal or any other acquisition of outstanding shares
of Acquired Company Stock other than  pursuant to the Merger or this  Agreement.
Notwithstanding the foregoing, nothing contained in this Agreement shall prevent
the Board of

                                      A-10
<PAGE>
Directors  of the  Acquired Company from  furnishing information  to or entering
into discussions  or negotiations  with any  unsolicited Person,  or taking  any
action  described in clauses (a) and (b)  of the preceding sentence, if and only
to the extent that  the Board of  Directors of the  Acquired Company shall  have
determined in good faith, after receiving written advice of its outside counsel,
that  such action would be required under  applicable law in the exercise of its
fiduciary duties. The Acquired Company will immediately notify the Purchaser  if
any  such  inquiries  or proposals  are  received  by, any  such  information is
requested from,  or  any such  negotiations  or  discussions are  sought  to  be
initiated  or continued  with the Acquired  Company. As used  in this Agreement,
"Takeover Proposal" shall  mean any  tender or exchange  offer, proposal,  other
than  a proposal  by Purchaser  or any  of its  affiliates, for  a merger, share
exchange or other  business combination  involving the Acquired  Company or  any
proposal  or offer to acquire in any manner a substantial equity interest in the
Acquired Company or a substantial portion of the assets of the Acquired Company.

    2.12  HSR  ACT FILINGS.   Parent  and the  Acquired Company  shall each,  in
cooperation  with the  other, make the  required filings in  connection with the
transactions contemplated by this Agreement under  the HSR Act with the  Federal
Trade  Commission and the Antitrust Division  of the United States Department of
Justice, and shall request early termination of the waiting period with  respect
to  such filings. As promptly as practicable from time to time after the date of
this Agreement, each party shall make all such further filings and  submissions,
and  take such further action,  as may be required  in connection therewith, and
shall furnish the other  all information in  its possession necessary  therefor.
Parent  and the  Acquired Company shall  each notify the  other immediately upon
receiving any request for  additional information with  respect to such  filings
from  either the Antitrust Division of the  Department of Justice or the Federal
Trade Commission, and the party receiving the request shall use its best efforts
to comply  with such  request as  soon  as possible.  Neither such  party  shall
withdraw any such filing or submission without the written consent of the other.

    2.13   TAX  REPORTING.   For federal and  state tax  purposes, Purchaser and
Parent shall  report  the  transactions  contemplated by  this  Agreement  as  a
reorganization  within the meaning of  Sections 368(a)(1)(A) and 368(a)(2)(D) of
the Tax Code and similar state laws.  Prior to the Effective Time, the  Acquired
Company  will  deliver  to  Purchaser  and  Parent  letters  to  the  reasonable
satisfaction of Purchaser and  Parent from the Acquired  Company and certain  of
its stockholders that when read together provide assurance that there is no plan
or  intention  on the  part  of the  stockholders  of the  Acquired  Company (or
knowledge of such plan or intent to  the extent the Acquired Company provides  a
representation  with respect to  holders of less  than five percent  (5%) of the
Acquired Company Stock) to  sell, exchange or otherwise  dispose of a number  of
shares  of Parent Stock  received in the  Merger that would  reduce the Acquired
Company's stockholders' ownership of  Parent Stock received in  the Merger to  a
number  of shares having a  value, as of the Effective  Time, of less than fifty
percent (50%) of the value of all  of the outstanding stock of Acquired  Company
immediately  prior to  the Effective  Time. Purchaser,  Parent and  the Acquired
Company agree  that satisfaction  of the  representations described  above  will
constitute   satisfaction  of  the  "continuity  of  interest"  requirement  for
reorganizations under Section 368(a) of the Tax Code. Each of Purchaser,  Parent
and  the Acquired Company shall use their  reasonable best efforts to obtain the
tax opinions described in 6.6 and 7.6 hereof.

    2.14   INDEMNIFICATION OF  ACQUIRED  COMPANY OFFICERS  AND DIRECTORS.    The
Purchaser  agrees that  it will  provide to  the directors  and officers  of the
Acquired Company indemnification  in accordance with  the current provisions  of
the  Certificate  of  Incorporation and  By-Laws  of the  Acquired  Company with
respect to matters  occurring prior  to the Effective  Time, including,  without
limitation,  this  Agreement and  the  transactions contemplated  hereby,  for a
period of  five years  from  the Effective  Time (or,  in  the case  of  matters
occurring  prior to the Effective Time which have not been resolved prior to the
fifth anniversary  of  the  Effective  Time,  until  such  matters  are  finally
resolved).  To the  fullest extent  permitted by  applicable law,  the Purchaser
shall advance expenses  in connection  with the  foregoing indemnification.  The
Parent  shall cause to be maintained in  effect for twelve (12) months following
the Closing the current policies of directors' and officers' liability insurance
currently maintained by the  Acquired Company, which  policies are described  on
EXHIBIT 3.19, at no

                                      A-11
<PAGE>
greater than one hundred percent (100%) of the annual premiums for such coverage
as  of the date  hereof (as reflected  on such EXHIBIT  3.19), provided that the
Parent may substitute therefor policies of at least the same coverage containing
terms and  conditions that  are no  less  advantageous. In  the event  that  the
premiums for the continued coverage exceed 100% of the premiums for the coverage
as  of the  date hereof (the  "100% Amount"), Purchaser  shall either substitute
coverage meeting the requirements  of the proviso in  the preceding sentence  or
continue  the existing  insurance but reduce  the maximum amount  of coverage to
that available for premiums equal to the 100% Amount.

    2.15   PUBLICATION OF  OPERATIONAL RESULTS.   Purchaser  agrees to  use  its
reasonable  best efforts to make publicly  available joint results of operations
of Parent and the Acquired Company in  respect of the first full calendar  month
subsequent  to Closing no later than twenty  (20) days following the end of such
calendar month.

    2.16  CONTINGENT REGISTRATION RIGHTS.  In the event that the average  weekly
reported  volume  of  trading  of  the Parent  Stock,  as  reported  through the
automated quotation system of  the Nasdaq Stock  Market National Market  System,
during  any four (4) calendar  week period ending on  any date within six months
following the Closing Date constitutes less than two percent (2%) of the  number
of shares of Parent Stock outstanding as of such date, Parent shall use its best
efforts  to  file  promptly  and  make effective  with  the  SEC  a Registration
Statement covering the Parent  Stock owned by Wind  Point Partners II, L.P.  (or
its  partners), Marshall D. Miller, his children, Phileona Foundation and Dorado
Investment Company (the "Selling  Stockholders") on the basis  set forth on  the
attached EXHIBIT 2.16. Parent acknowledges and agrees that this covenant is made
for the express benefit of the Selling Stockholders.

business  and in  good standing  as a  foreign corporation  in the jurisdictions
listed in EXHIBIT 3.1 hereto, and the character of the property owned or  leased
by  the Acquired Company and the nature of the business conducted by it does not
require such qualification and/or licensing in any other jurisdiction where  the
failure  to so qualify  would have a  Material Adverse Effect  upon the Acquired
Company.

    3.2  AUTHORITY AND STATUS.

    3.2.1.  The Board of Directors of the Acquired Company, by unanimous vote of
all directors present at a meeting duly called and held, has (i) determined that
the Merger is  fair to  and in  the best interests  of the  stockholders of  the
Acquired  Company  and  (ii) resolved  to  submit  the Merger  to  and recommend
approval of the Merger by the stockholders of the Acquired Company.

    3.2.2.  The Acquired Company has  the capacity and authority to execute  and
deliver  this  Agreement,  to  perform  hereunder,  and,  upon  approval  of the
transactions  provided  for  herein  by  its  stockholders,  to  consummate  the
transactions  contemplated  hereby without  any  other corporate  or stockholder
approval. The execution,  delivery and  performance by the  Acquired Company  of
this  Agreement  and each  and every  other  agreement, document  and instrument
provided for  herein have  been duly  authorized and  approved by  the Board  of
Directors  of the Acquired  Company. Assuming this Agreement  and each and every
agreement, document or instrument to be executed, delivered and performed by the
Acquired  Company  in  connection  herewith   are  valid  and  legally   binding
obligations  of  Purchaser  and  Parent,  this  Agreement  and  each  and  every

<PAGE>

obligation of the  Acquired Company  enforceable against it  in accordance  with
their  respective terms, except  as enforceability may  be limited by applicable
equitable principles or by  bankruptcy, insolvency, reorganization,  moratorium,
or  similar  laws from  time  to time  in  effect affecting  the  enforcement of
creditors' rights generally. Attached  hereto as EXHIBIT  3.2 are true,  correct
and  complete  copies of  the  Certificate of  Incorporation  and Bylaws  of the
Acquired Company.

    3.2.3.  The Board of Directors  of the Acquired Company received an  opinion

such stockholders from a financial point of view.

    3.3  CAPITALIZATION.   The entire authorized capital  stock of the  Acquired
Company  consists of thirty-five million (35,000,000)  shares of stock, of which

consummate the transactions  contemplated herein  by virtue of  any such  Person
having  an equitable or beneficial interest in the capital stock of the Acquired
Company. Except as set forth on  EXHIBIT 3.3, there are no outstanding  options,
warrants,  calls, commitments or plans by the Acquired Company or any Subsidiary
to issue any additional  shares of its  capital stock, to  pay any dividends  on
such  shares or  to purchase,  redeem, or retire  any outstanding  shares of its
capital stock, nor are there outstanding any securities or obligations that  are
convertible into or exchangeable for any shares of capital stock of the Acquired
Company.  Other than as disclosed on EXHIBIT 3.3,  there are not now, and at the
Effective Time  there will  not be,  any voting  trusts or  other agreements  or
understandings to which the Acquired Company is a party or is bound with respect

years through the  year ended December  31, 1990, and  all taxes,  deficiencies,

    3.16.2.  EXHIBIT 3.16 also lists,  with respect to all Benefit Plans  listed

trusts subject to ERISA  comply with and have  been administered in  substantial
compliance with the applicable provisions of ERISA, all applicable provisions of
the Tax Code relating to qualification and tax exemption under Tax Code Sections
401(a)  and 501(a) or  otherwise necessary to  secure intended tax consequences,
all applicable state or federal securities  laws and all other applicable  laws,
rules and regulations, and the Acquired Company has not received any notice from
any  governmental  agency  or instrumentality  questioning  or  challenging such
compliance. Any  noncompliance  or  failure properly  to  maintain,  operate  or
administer a Benefit Plan or related trust has not rendered nor will render such
Benefit  Plan  or related  trust or  the Parent,  Purchaser or  Acquired Company
subject to or liable  for any material taxes,  penalties, or liabilities to  any
Person.

    3.16.4.  None of the Acquired Company, and, to the knowledge of the Acquired
Company,  any administrator or fiduciary  of any such Benefit  Plan (or agent or
delegate of any of  the foregoing) has  engaged in any  transaction or acted  or
failed  to act  in any  manner that  could subject  the Acquired  Company to any
direct or indirect  liability (by indemnity  or otherwise) for  a breach of  any
fiduciary,  co-fiduciary or  other duty under  ERISA that would  have a Material
Adverse Effect on  the Company. No  material oral or  written representation  or
communication  with respect to any aspect of  the Benefit Plans has been or will
be made to employees of the Acquired  Company prior to the Closing Date that  is
not in accordance with the written or otherwise preexisting terms and provisions
of  such Benefit Plans in  effect immediately prior to  the Closing Date, except
for any amendments or terminations required  by the terms of this Agreement  and
except for any such representation or communication as would not have a Material
Adverse Effect on the Acquired Company. To the knowledge of the Acquired Company
there  are no pending  unresolved claims or  disputes under the  terms of, or in
connection with, the  Benefit Plans  (other than routine  undisputed claims  for

    3.16.5.   To the  knowledge of the  Acquired Company, all  annual reports or
returns,  audited  or  unaudited  financial  statements,  actuarial  valuations,
summary  annual reports and summary plan descriptions issued with respect to the
Benefit Plans are correct and accurate in all material respects as of the  dates
thereof;  and  there have  been  no amendments  filed  to any  of  such reports,
returns,  statements,  valuations  or  descriptions  or  required  to  make  the
information  therein true  and accurate. All  annual reports  (Form 5500 series)
required to be filed with respect to  any Current Plan for the Plan year  ending
in 1994 have been or will be timely filed prior to Closing.

    3.16.6.    No non-exempt  "prohibited  transaction" (within  the  meaning of
4975(c) of the Tax  Code involving any  Benefit Plan has  occurred. None of  the
assets  of  any ERISA  Plan is  an  "employer security"  (within the  meaning of
Section 407(d)(1) of ERISA) or "employer  real property" (within the meaning  of
Section 407(d)(2) of ERISA).

    3.16.7.   The  only Benefit Plan  that is  or has been  an "employee pension
benefit plan" as defined in Section 3(2) of ERISA is the 401(k) Plan. The 401(k)
Plan is qualified under Section 401(a) of the Tax Code and its related trust  is
exempt  from tax under Section 501(a) of the Tax Code and no circumstances exist
that could result in a disqualification of the 401(k) Plan or loss of tax-exempt
status for its related trust  that would have a  Material Adverse Effect on  the
Acquired Company. Neither the 401(k) Plan nor any predecessor plan has ever been
subject  to  the provisions  of  Title IV  of ERISA  or  to the  minimum funding
standards of Section 412 of the Tax Code.

    3.16.8.  As of March 31, 1995, the Acquired Company had no current or future
liability with respect to any events  or matters occurring, arising or  accruing
on  or prior to such date  under any Benefit Plan that  was not reflected in the
Interim 1995  Acquired  Company  Financial  Statements and  that  would  have  a
Material Adverse Effect on the Acquired Company.

    3.16.9.    Neither  the Acquired  Company  nor  any ERISA  Affiliate  of the
Acquired Company  has maintained,  and  neither now  maintains, a  Benefit  Plan
providing welfare benefits (as defined in ERISA Section 3(1)) to employees after
retirement  or other separation  of service except to  the extent required under
Part 6 of Title I of ERISA and Tax Code Section 4980B.

    3.16.10.  Except as  set forth on EXHIBIT  3.16.10, the consummation of  the
transactions  contemplated by this Agreement will not (i) entitle any current or
former employee  (or  any spouse,  dependent  or  other family  member  of  such
employee) of the Acquired Company to severance pay, unemployment compensation or
any  payment contingent upon  a change in  control or ownership  of the Acquired
Company, or (ii)  accelerate the  time of payment  or vesting,  or increase  the
amount,  of any compensation due to any such employee or former employee (or any
spouse, dependent or other family member of such employee).

    3.17  CUSTOMERS.  Except as set forth in EXHIBIT 3.17, as of the date hereof
the Acquired Company has  not received any  notice from, and  does not have  any
knowledge  that, any current customer of the  Acquired Company has taken or will
take any steps  that could  disrupt the  business relationship  of the  Acquired
Company  with such customer  in any material respect.  The Acquired Company will
not suffer subsequent to the date hereof and prior to the Closing any damage  to
the  business relationship of the Acquired  Company with any current customer or
customers of the Acquired  Company that would have  in the aggregate a  Material
Adverse Effect.

products used by  the Acquired Company  in the ordinary  course of business  and
except  as set forth in EXHIBIT 3.18,  no real property now or previously owned,

tribunal and, to the knowledge of  the Acquired Company, there is no  reasonable
basis  for any  such claim, action,  suit, proceeding or  investigation (i) with
respect to the Real Property (a) by virtue  of the actions or failure to act  of
the  Acquired Company or (b) to the knowledge of the Acquired Company, by virtue
of the actions or failure to act  of any other party, or (ii) otherwise  against
the  Acquired Company or any Subsidiary. Except as disclosed on EXHIBIT 3.18, to
the knowledge of the Acquired Company, there are no underground storage tanks on
the Real Property.  To the  knowledge of the  Acquired Company,  no building  or
other  improvement included in the Real Property contains any exposed or friable
asbestos currently required to be removed or otherwise treated under  applicable
law.  For the purposes  of this Agreement, "Hazardous  Substance" shall mean any

material  insurance policies that the Acquired Company maintains with respect to
its businesses, properties or  employees. Except as set  forth in EXHIBIT  3.19,
such  policies are in full force and effect and no event has occurred that would
give any insurance carrier a right  to terminate any such policy. Such  policies
are  adequate to  insure against  risks to  which the  Acquired Company  and its
properties and  assets are  exposed in  the operation  of its  business in  such
amounts  and types of coverage as are commercially reasonable and are consistent
with practices in the industry in which the Acquired Company operates. Except as
set forth in EXHIBIT 3.19, since March  31, 1995, there has not been any  change
in  the Acquired  Company's relationship  with its  insurers or  in the premiums
payable pursuant to such policies.

the  knowledge of  the Acquired  Company, no  stockholder owning  greater than a
five-percent (5%) interest in  the Acquired Company, no  affiliate or member  of
the  immediate family  of any  such stockholder, and  no officer  or director or
member of  the immediate  family of  such officer  or director  of the  Acquired
Company  possesses, directly or indirectly, any  beneficial interest in, or is a

IV.  REPRESENTATIONS AND WARRANTIES OF PURCHASER AND PARENT.

    Purchaser  and Parent, jointly  and severally, represent  and warrant to the
Acquired Company as follows:

    4.1  ORGANIZATION  AND STANDING.   Each of  Purchaser and Parent  is a  duly
organized  and validly existing  corporation in good standing  under the laws of
the State of Delaware.

    4.2  CORPORATE POWER AND  AUTHORITY.  Each of  Purchaser and Parent has  the
capacity  and  authority  to  execute and  deliver  this  Agreement,  to perform
hereunder and to  consummate the  transactions contemplated  hereby without  the
necessity  of any act or consent of  any other Person whomsoever. The execution,
delivery and performance by Purchaser and Parent of this Agreement and each  and
every  agreement, document  and instrument  provided for  herein have  been duly
authorized and approved by  their respective Boards  of Directors (or  Executive
Committees   thereof).  Assuming  this  Agreement,  and  each  and  every  other
agreement, document and instrument  to be executed,  delivered and performed  by
Purchaser and Parent in connection herewith are valid and legally binding on the
Acquired  Company, this Agreement, and each  and every other agreement, document
and instrument to be executed, delivered  and performed by Purchaser and  Parent
in  connection  herewith,  constitute  or  will,  when  executed  and delivered,
constitute the valid and legally binding obligations of Purchaser and Parent  as
applicable, enforceable against each of them in accordance with their respective
terms,   except  as  enforceability  may  be  limited  by  applicable  equitable
principles, or by bankruptcy, insolvency, reorganization, moratorium, or similar
laws from time to time in effect affecting the enforcement of creditors'  rights
generally.

    4.3   CAPITALIZATION.   The  entire authorized  capital stock  of the Parent
consists of  sixty-one million  (61,000,000)  shares of  stock, of  which  sixty
million  (60,000,000) shares  are designated  Common Stock,  par value  $.05 per
share, and one million (1,000,000) shares are designated Preferred Stock, no par
value per share ("Parent Preferred Stock"). Of the total authorized Common Stock
as of June 30, 1995, approximately fifty-three million one hundred one  thousand
(53,101,000)  shares were issued, of  which approximately thirty-six million one
hundred ninety-seven thousand (36,197,000)

                                      A-22
<PAGE>
shares were  outstanding and  approximately sixteen  million nine  hundred  four
thousand  shares were  held in  the Parent's  treasury. Of  the total authorized
Preferred Stock, none were outstanding. On February 12, 1991, Parent declared  a
dividend  distribution of one  Preferred Share Purchase Right  for each share of
Parent Stock. As of June 30, 1995 none of such Rights had been exercised. As  of
June  30,  1995, Parent  had  an aggregate  of  approximately one  million three
hundred  sixteen  thousand  ninety-seven  (1,316,097)  shares  of  Common  Stock
reserved  for issuance under previously approved employee stock option, purchase
or benefit plans. All of the  outstanding shares of Parent Stock (including  any
shares  issued pursuant  to existing  Parent stock  option, purchase  or benefit
plans, if exercised and purchased at  the applicable exercise price) and  Parent
Preferred  Stock were duly authorized (or will  be when issued and the option or
purchase price is paid), validly issued,  fully paid and nonassessable. None  of
the capital stock of the Parent is entitled or subject to preemptive rights. All
of  the outstanding capital stock  of the Purchaser is  owned by the Parent. The
authorization or consent of no  other person or entity  is required in order  to
consummate  the transactions as contemplated herein by virtue of any such person
or entity  having an  equitable or  beneficial  interest in  the Parent  or  the
Purchaser or in the capital stock of the Parent or the Purchaser.

    4.4    AGREEMENT DOES  NOT  VIOLATE OTHER  INSTRUMENTS.   The  execution and

with information previously furnished by Parent to the Acquired Company, did not
contain any untrue statement of a material fact or omit to state a material fact
required  to be stated therein or necessary to make the statements made therein,
in light of the circumstances in which  they were made, not misleading. As  used
in  this Section, "material" means material  to the financial condition, results
of operations,  business,  assets or  properties  of Parent  together  with  its

Statements"). The 1992, 1993, 1994 and Interim 1995 Parent Financial  Statements
have  been prepared in accordance with generally accepted accounting principles,
consistently  applied,  and  fairly  present   in  all  material  respects   the
consolidated  financial condition and statements of  cash flow of the Parent and
its subsidiaries (including the  Purchaser) as of  the respective dates  thereof
(subject,  in the case of  the Interim 1995 Parent  Financial Statements, to the
absence of footnotes and to normal year-end adjustments).

    4.8  ABSENCE OF CERTAIN CHANGES OR  EVENTS.  Except as disclosed on  EXHIBIT
4.8,  since March 31,  1995, the Parent  has operated in  the ordinary course of

    4.10   POOLING OF INTERESTS.  The Parent  and the Purchaser are not aware of
any facts  or  circumstances  respecting  either  thereof  or  their  accounting
procedures  which would have the effect of precluding accounting for transaction
contemplated hereby as a "pooling of interests."

VI. FURTHER CONDITIONS PRECEDENT TO OBLIGATIONS OF PURCHASER AND PARENT.

    In  addition  to  the conditions  set  forth  in Article  V  above,  all the
obligations of Purchaser and Parent to  consummate, or cause to be  consummated,
the  Merger shall  be contingent  upon and  subject to  the satisfaction,  on or
before the  Closing, of  each and  every one  of the  following conditions.  The
following conditions are for the sole benefit of Purchaser and Parent and may be
waived  by Purchaser or  Parent (which action  shall be deemed  a waiver by both
Purchaser and Parent), in whole or in part,  at any time and from time to  time,
in  the sole discretion of Purchaser or  Parent. The failure by either Purchaser
or Parent at  any time  to exercise  any of the  foregoing rights  shall not  be
deemed  a waiver of any  other right, and each right  shall be deemed an ongoing
right that may be asserted at any time and from time to time.

    6.1    REPRESENTATIONS  OF  ACQUIRED  COMPANY.    All  representations   and

Agreement there shall not  have been any Material  Adverse Effect in respect  of
the  Acquired Company.  A Material  Adverse Effect shall  not be  deemed to have
occurred for purposes of this Section 6.3 by reason of the inability of Acquired
Company to enter into contracts with those prospective new customers which prior
to the execution of this Agreement have been separately identified in a  writing
by  Acquired  Company to  Purchaser substantially  due to  the reaction  of such
prospective new customers to the  announcement of the transactions  contemplated
by this Agreement. In addition, a Material Adverse Effect shall not be deemed to
have  occurred for purposes of this Section 6.3 as a result of reductions in the
volume of

                                      A-25
<PAGE>
revenue received by Acquired Company from Purchaser where such reduction is  the

into contracts with prospective new customers.

        10.1.4.   by  Purchaser after  the Outside Closing  Date, if  any of the
    conditions set forth in Articles V  and VI hereof, to which the  obligations

    termination is required; or

        10.1.6.   by the  Board of  Directors  of the  Acquired Company  if  the
    average  of the per share  closing prices of the  Parent Stock on the Nasdaq

    any  period of twenty (20) consecutive trading days ending on any date prior
    to the second trading day prior to the Closing Date is less than $50.00.

    10.2  EFFECT OF TERMINATION.

    10.2.1.   In  the event  of  a termination  of  this Agreement  pursuant  to
Sections  10.1, each party  shall pay the  costs and expenses  incurred by it in
connection with this Agreement,  and except as provided  in the next  succeeding
sentence,  no  party  (or any  of  its officers,  directors,  employees, agents,
representatives or stockholders)  shall be  liable to  any other  party for  any
costs,  expenses, damage or loss of  anticipated profits hereunder. In the event
of a  termination of  this Agreement  other than  pursuant to  Sections  10.1.1,
10.1.5,  and 10.1.6, the parties shall retain  any and all rights attendant to a
breach of any covenant, representation  or warranty made hereunder. The  parties
agree  that the failure to  be satisfied of any  condition to Closing shall not,
absent a  breach  of  any  covenant, representation  or  warranty  made  herein,
constitute  a  breach of  this  Agreement; although  a  breach of  any covenant,
representation or warranty  that results in  or constitutes the  failure of  any
condition  to Closing shall nonetheless constitute  a breach for purposes of the
immediately preceding sentence. The parties also agree that Sections 5, 6 and  7
do not in and of themselves constitute representations, warranties or covenants.
Each party further agrees not to take any actions with the intent of frustrating
the satisfaction of the conditions to its obligation to close. In the event of a
termination  of this Agreement pursuant to Section 10.1.5 hereof, Section 10.2.2
shall govern.

    10.2.2.  In the event the Agreement is terminated by the Acquired Company in
accordance with  Section 10.1.5,  the  Acquired Company  shall promptly  pay  to
Purchaser  (i) in  an aggregate  amount not  to exceed  $500,000, all reasonable
costs and  expenses of  Purchaser and  Parent incurred  in connection  with  the
negotiation  and performance of this Agreement including without limitation fees
and expenses of counsel,  fees and expenses  of independent public  accountants,
filing  fees in respect  of compliance with  the HSR Act,  printing expenses and
registration fees and (ii) a fee in the amount of $1,500,000. In the case of any
termination of  this Agreement  under  Section 10.1.5,  payment of  the  amounts
specified  in  the preceding  sentence shall  constitute liquidated  damages and
shall be the sole and exclusive remedy  of Parent and Purchaser for any and  all
damages arising under or in connection with this Agreement, and, upon payment of
the  amounts specified in the preceding sentence, the Acquired Company shall not
have any liability  or further  obligation to Parent  or Purchaser  under or  in
connection with this Agreement or any such termination hereof.

    10.2.3.   Notwithstanding  anything in this  Agreement to  the contrary, the
provisions of  Section 2.8.2  shall survive  any termination  of this  Agreement
prior to Closing.

    10.3   RISK OF LOSS.  The Acquired Company retains all risk of condemnation,
destruction, loss or damage due to fire or other casualty from the date of  this
Agreement  up to the Effective Time.  If the condemnation, destruction, loss, or
damage is such  that the  business of the  Acquired Company,  is interrupted  or
curtailed or the assets of the Acquired Company are adversely affected such that
a  Material  Adverse  Effect Occurs,  then  Purchaser  shall have  the  right to
terminate this Agreement.

September 1, 1995
    

Board of Directors
CliniCom Incorporated
4720 Walnut Street
Boulder, CO 80301

Ladies and Gentlemen:

    CliniCom  Incorporated,  a  Delaware  corporation  (the  "Company"),  HBO  &
Company, a  Delaware corporation  ("HBOC"),  and HBO  &  Company of  Georgia,  a
Delaware  corporation and a  wholly owned subsidiary  of HBOC (the "Purchaser"),
have entered  into an  Agreement  of Merger,  dated as  of  July 14,  1995  (the
"Agreement"),  providing  for  the  merger  of the  Company  with  and  into the
Purchaser (the "Merger"). The Agreement provides that each outstanding share  of
common  stock, par value  $.001 per share,  of the Company  (the "Company Common
Stock") issued  and outstanding  immediately  prior to  the Effective  Time  (as
defined  in the Agreement), shall at the Effective Time, by virtue of the Merger
and without any action on the part of the holder thereof, be converted into  the
right  to receive  four-tenths (4/10ths)  of a  share (the  "Exchange Ratio") of
common stock,  par value  $.05 per  share, of  HBOC (the  "HBOC Common  Stock"),
deliverable  to the holder  thereof, without interest on  the value thereof. The
Company is not required to consummate the Merger if the average of the per share
closing prices on the  Nasdaq's National Market as  reported in THE WALL  STREET
JOURNAL  of the  HBOC Common  Stock for  the ten  (10) consecutive  trading days
ending on the second trading  day prior to the Closing  Date (as defined in  the
Agreement) is less than $50.00.

    You  have requested our opinion, as  investment bankers, as to the fairness,
from a financial  point of  view, to  the stockholders  of the  Company, of  the
Exchange Ratio.

    In arriving at the opinion set forth below, we have, among other things:

(1) reviewed the Agreement;

   
(2)  reviewed the  Annual Reports  on Form  10-K and  related publicly available
    financial information of the Company for the three most recent fiscal  years
    ended December 31, 1994, the final prospectus, dated April 20, 1992, for the
    Company's  initial public offering of Common  Stock, the Quarterly Report on
    Form 10-Q for the period ended  June 30, 1995, and the Company's  definitive
    Proxy Statement on Schedule 14A, dated May 3, 1995;
    

   
(3)  reviewed the  Annual Reports  on Form  10-K and  related publicly available
    financial information of HBOC for the  three most recent fiscal years  ended
    December  31, 1994, the Quarterly  Report on Form 10-Q  for the period ended
    June 30, 1995, and HBOC's definitive Proxy Statement on Schedule 14A,  dated
    April 3, 1995;
    

(4)   reviewed   certain   other  information,   including   publicly  available
    information, relating  to  the business,  earnings,  cash flow,  assets  and
    prospects of the Company and HBOC, respectively;

(5)  reviewed  an income  statement forecast  of the  Company for  the remaining
    portion of the 1995 fiscal year and for the fiscal year 1996 as furnished to
    us by the  Company; reviewed balance  sheet and cash  flow forecasts of  the
    Company for the remaining portion of the 1995 fiscal year and for the fiscal
    year  1996 as prepared on the basis of information and assumptions furnished
    to us by the Company;

(6) reviewed income statement forecasts of HBOC for the remaining portion of the
    1995 fiscal year and for the fiscal year 1996 as furnished to us by HBOC;

(7) conducted discussions with members of  senior management of the Company  and
    HBOC,  respectively, concerning  the past and  current business, operations,
    assets, present financial condition and future prospects of the Company  and
    HBOC, respectively;

(8)  reviewed the historical reported market prices and trading activity for the
    Company Common Stock and HBOC Common Stock;

                                      B-1
<PAGE>
(9) compared  certain financial  information,  operating statistics  and  market
    trading  information  relating  to  the  Company  with  published  financial
    information, operating statistics and market trading information relating to
    selected public companies  that we deemed  to be reasonably  similar to  the
    Company;  compared certain  financial information,  operating statistics and
    market  trading  information  relating  to  HBOC  with  published  financial
    information, operating statistics and market trading information relating to
    selected public companies that we deemed to be reasonably similar to HBOC;

(10)  compared the  proposed financial  terms of  the Merger  with the financial
    terms,  to  the  extent  publicly   available,  of  selected  other   recent
    acquisitions that we deemed to be relevant; and

(11) reviewed such other financial studies and analyses and performed such other
    investigations  and  took  into  account such  other  matters  as  we deemed
    necessary.

   
    In preparing our opinion, we have  assumed and relied upon the accuracy  and
completeness  of  all financial  and  other information  supplied  to us  by the
Company and HBOC or  that is publicly available,  respectively, and we have  not
independently  verified such information. We have also assumed that the Software
License and  Distribution Agreement,  Teaming  Agreement, Software  Support  and
Enhancement  Agreement, and Software Development  Agreement, each dated December
24, 1993 and entered into between the Company and HBO & Company of Georgia, have
not been materially modified  or amended since the  dates thereof. We also  have
relied  upon the managements  of the Company  and HBOC, respectively,  as to the
reasonableness and achievability of the  financial forecasts of the Company  and
HBOC  (and the assumptions and bases thereof)  provided to us or prepared on the
basis of information and assumptions furnished  to us, and with your consent  we
have  assumed that  such forecasts  have been  reasonably prepared  on the basis
reflecting  the  best  currently  available  estimates  and  judgments  of  such
respective managements as to the future operating performance of the Company and
HBOC,  respectively. Furthermore,  we assumed  the Merger  will qualify  (i) for
pooling of interests accounting  treatment and (ii)  as a reorganization  within
the  meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.
We have  not been  requested  to make,  and we  have  not made,  an  independent
appraisal  or evaluation of the assets, properties, facilities or liabilities of
the Company or HBOC and  we have not been furnished  with any such appraisal  or
evaluation.
    

    It  should be noted  that this opinion necessarily  is based upon prevailing
market conditions (including current market prices for the Company Common  Stock
and  the HBOC Common Stock) and other circumstances and conditions as they exist
and can be evaluated at this time, and does not represent our opinion as to what
the actual value of the  Company Common Stock or the  HBOC Common Stock will  be
after the date hereof.

    We  have acted as financial advisor to the Board of Directors of the Company
in connection with this transaction and will  receive a fee for our services,  a
portion of which is contingent upon the consummation of the Merger. In addition,
in  the ordinary course of our business, we actively trade the securities of the
Company and HBOC  for our own  account and  for the accounts  of customers  and,
accordingly,  may at any time hold a  long or short position in such securities.
In addition, we have not acted as  financial advisor to HBOC, nor have we  acted
as  manager of any HBOC security offering, and have not received any advisory or
offering fees from  HBOC. We do,  however, in the  ordinary course of  business,
provide our clients with research coverage of both the Company and HBOC.

    On  the basis  of, and subject  to the  foregoing and other  matters that we
consider pertinent, we  are of  the opinion  that, AS  OF THE  DATE HEREOF,  the
Exchange  Ratio is fair, from  a financial point of view,  to the holders of the
outstanding Company Common Stock.

Very truly yours,

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    HBO & Company's (the "Company") By-Laws (Article IX, Section 1) provide that
every  person who was or is a party or is threatened to be made a party to or is
involved  in  any   action,  suit  or   proceeding,  whether  civil,   criminal,
administrative  or investigative, by reason  of the fact that  he or a person of
whom he is  the legal  representative is  or was a  director or  officer of  the
corporation  or is or was  serving at the request of  the corporation or for its
benefit  as  a  director   or  officer  of  another   corporation,  or  as   its
representative in a partnership, joint venture, trust or other enterprise, shall
be indemnified and held harmless to the fullest extent legally permissible under
and  pursuant to any procedure  specified in the General  Corporation Law of the
State of  Delaware,  as  amended  from  time  to  time,  against  all  expenses,
liabilities  and losses (including attorneys' fees, judgments, fines and amounts
paid or to  be paid in  settlement) reasonably  incurred or suffered  by him  in
connection  therewith. Such right  of indemnification shall  be a contract right
that may be enforced in any manner by such person. Such right of indemnification
shall not be  exclusive of  any other right  which such  directors, officers  or
representatives  may  have  or  thereafter  acquire  and,  without  limiting the
generality of such statement,, they shall be entitled to their respective rights
of indemnification under any bylaw,  agreement, vote of stockholders,  provision
of law or otherwise, as well as their rights under such article.

    Article  IX, Section 2 of  the Company's By-Laws provides  that the Board of
Directors may cause the corporation to purchase and maintain insurance on behalf
of any person who is or was a  director or officer of the corporation, or is  or
was  serving  at the  request of  the corporation  as a  director or  officer of
another corporation, or as its  representative in a partnership, joint  venture,
trust or other enterprise against any liability asserted against such person and
incurred  in any such capacity or arising out of such status, whether or not the
corporation would have the power to indemnify such person.

    With respect to indemnification  of officers and  directors, Section 145  of
the  Delaware General  Corporation Law  provides that  a corporation  shall have
power to indemnify any person who was or is a party or is threatened to be  made
a  party to  any threatened,  pending or  completed action,  suit or proceeding,
whether civil, criminal, administrative, or investigative (other than an  action
by or in the right of the corporation) by reason of the fact that he is or was a
director,  officer, employee, or agent of the  corporation, or is or was serving
at the request of the corporation as a director, officer, employee, or agent  of
another  corporation, partnership,  joint venture,  trust, or  other enterprise,
against expenses including attorneys' fees), judgments, fines, and amounts  paid
in  settlement actually and  reasonably incurred by him  in connection with such
action, suit  or proceeding  if  he acted  in  good faith  and  in a  manner  he
reasonably  believed  to be  in  or not  opposed to  the  best interests  of the
corporation, and, with  respect to  any criminal  action or  proceeding, had  no
reasonable  cause to believe  his conduct was unlawful.  Under this provision of
the Delaware General  Corporation Law, the  termination of any  action, suit  or
proceeding  by judgment, order,  settlement, conviction, or upon  a plea of nolo
contenders or its equivalent,  shall not, of itself,  create a presumption  that
the  person  did not  act in  good faith  and  in a  manner which  he reasonably
believed to be in or not opposed to the best interests of the corporation,  and,
with  respect  to any  criminal action  or proceeding,  had reasonable  cause to
believe that his conduct was unlawful.

    Furthermore,  the  Delaware   General  Corporation  Law   provides  that   a
corporation shall have power to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending, or completed action or
suit by or in the right of the corporation to procure a judgment in its favor by
reason  of the fact that he is or was a director, officer, employee, or agent of
the corporation, or is  or was serving  at the request of  the corporation as  a
director, officer, employee, or agent of another corporation, partnership, joint
venture,  trust,  or other  enterprise,  against expenses  (including attorneys'
fees), actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he  acted in good faith and in a manner  he
reasonably  believed  to be  in  or not  opposed to  the  best interests  of the
corporation except that no indemnification shall be made

                                      II-1
<PAGE>
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the corporation unless and only to the extent that  the
Court  of Chancery or the  court in which such action  or suit was brought shall
determine upon application that, despite  the adjudication of liability, but  in
view  of all  circumstances of  the case, such  person is  fairly and reasonably
entitled to indemnity  for such  expenses which the  Court of  Chancery or  such
other court shall deem proper.

    In  addition, the  General Corporation  Law of  Delaware enables  a Delaware
corporation  to  include  in  its  certificate  of  incorporation  a   provision
eliminating  or  limiting  a  director's liability  to  the  corporation  or its
stockholders for monetary damages for breaches of a director's fiduciary duty as
a director. The statute provides, however, that liability for (a) breach of  the
director's duty of loyalty, (b) acts or omissions not in good faith or involving
intentional  misconduct or knowing violations of  law, (c) the unlawful purchase
or redemption of stock  or unlawful dividends or  (d) transactions from which  a
director derived an improper personal benefit cannot be eliminated or limited in
this   manner.  The   Company's  Certificate  of   Incorporation  contains  such
provisions.

ITEM 22.  UNDERTAKINGS.

    (a) (i) The undersigned registrant  hereby undertakes that, for purposes  of
determining  any liability under the Securities Act  of 1933, each filing of the
registrant's annual report  pursuant to Section  13(a) or Section  15(d) of  the
Securities  Exchange  Act of  1934  (and, where  applicable,  each filing  of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of  1934)  that is  incorporated  by reference  in the
registration statement  shall  be deemed  to  be a  new  registration  statement
relating  to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

    (ii) (1) The undersigned registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is  a part  of this registration  statement, by  any person  or
party   who   is  deemed   to   be  an   underwriter   within  the   meaning  of

                                      II-5
<PAGE>
Rule 145(c), the issuer undertakes that such reoffering prospectus will  contain
the  information called for by the  applicable registration form with respect to
reofferings by  persons who  may  be deemed  underwriters,  in addition  to  the
information called for by the other Items of the applicable form.

        (2)  The registrant undertakes  that every prospectus  (i) that is filed
pursuant to paragraph (1) immediately preceding,  or (ii) that purports to  meet
the  requirements of Section 10(a)(3) of the  Act and is used in connection with
an offering of securities  subject to Rule 415,  will be filed as  a part of  an
amendment  to  the  registration  statement  and will  not  be  used  until such
amendment is  effective, and  that, for  purposes of  determining any  liability
under  the Securities Act  of 1933, each such  post-effective amendment shall be
deemed to be  a new registration  statement relating to  the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

    (iii)  Insofar  as  indemnification   for  liabilities  arising  under   the
Securities  Act of 1933 may be  permitted to directors, officers and controlling
persons of the registrant  pursuant to the  foregoing provisions, 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 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 the Act and  will
be governed by the final adjudication of such issue.

    (b)  The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated  by reference into  the prospectus pursuant  to
Items  4, 10(b), 11, or 13  of this Form, within one  business day of receipt of
such request, and  to send  the incorporated documents  by first  class mail  or
other  equally prompt  means. This  includes information  contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

    (c) The undersigned  registrant hereby undertakes  to supply by  means of  a
post-effective  amendment  all  information concerning  a  transaction,  and the
company being  acquired  involved therein,  that  was  not the  subject  of  and
included in the registration statement when it became effective.

HBO & COMPANY
301 PERIMETER CENTER NORTH
ATLANTA, GEORGIA 30346

Gentlemen:

   
    We  have acted  as counsel  to HBO  & Company,  a Delaware  corporation (the
"Company"), in connection with  the registration of  3,981,407 shares of  Common
Stock,  $.05 par value per share, of the Company (the "Shares"), to be issued by
the Company  pursuant  to  a  Registration  Statement  on  Form  S-4  (File  No.
33-61905),  filed with the Securities and Exchange Commission (the "Registration
Statement").
    

    We have  examined  originals or  certified  or photostatic  copies  of  such
records  of the  Company, certificates  of officers  of the  Company, and public
officials and such other  documents as we have  deemed relevant or necessary  as
the basis of the opinion set forth below in this letter. In such examination, we
have  assumed  the genuineness  of all  signatures,  the conformity  to original
documents submitted as certified or photostatic copies, and the authenticity  of
originals  of  such latter  documents. Based  on  the foregoing,  we are  of the
following opinion:

            The Shares have been duly authorized and, when issued in the  manner
            contemplated  by the Registration Statement, will be validly issued,
            fully paid and nonassessable.

    We hereby  consent  to the  filing  of this  opinion  as Exhibit  5  to  the
Registration Statement and the reference to this Firm under the heading "Certain
Legal  Matters"  in  the  Proxy Statement/Prospectus  constituting  part  of the
Registration Statement.

                                          Sincerely,

   
                                          /s/

            ---------------------------------------------------
Dear Sirs:

    We  have acted  as counsel to  CliniCom Incorporated in  connection with the
Registration Statement on Form S-4, to  which this opinion appears as Exhibit  8
(the  "Registration Statement"), which includes  the Proxy Statement of CliniCom
Incorporated and the Prospectus  of HBO &  Company. Unless otherwise  indicated,
any  defined terms used herein shall have the same meanings that such terms have
in the  Proxy Statement/Prospectus.  We hereby  confirm that,  assuming the  due
receipt  of customary representations as referred  to under the heading "Certain
Federal Income  Tax  Consequences" in  the  Proxy Statement/Prospectus,  in  our
opinion  the statements attributed to us in the Proxy Statement/Prospectus under
the heading  "Certain  Federal Income  Tax  Consequences" are  accurate  in  all
material respects.

   
    We  hereby consent to the filing with the Securities and Exchange Commission
of this  opinion  as  an  exhibit  to the  Registration  Statement  and  to  the
references  to this Firm in the Proxy Statement/ Prospectus constituting part of
the Registration Statement.
