To Our Stockholders:

    You  are cordially  invited to attend  a Special Meeting  of Stockholders of
Horizon Healthcare Corporation at the Albuquerque Marriott Hotel, 2102 Louisiana
Avenue, N.E., Albuquerque, New Mexico on July 6, 1995, at 10:00 a.m., local time
(the "Special Meeting").

    At the  Special Meeting,  you will  be asked  to consider  and vote  upon  a
proposal  to approve and  adopt the Amended  and Restated Agreement  and Plan of
Merger dated  as of  May 23,  1995 (the  "Merger Agreement")  providing for  the
merger  (the  "Merger")  of  a wholly  owned  subsidiary  of  Horizon Healthcare
Corporation with and into Continental Medical Systems, Inc. ("CMS"). The  Merger
Agreement  provides  that,  upon consummation  of  the Merger,  each  issued and
outstanding share of common stock of CMS would be converted into .5397 shares of
Horizon Common Stock and CMS would become a wholly owned subsidiary of  Horizon.
The  Merger  Agreement  and the  Merger  are  discussed in  more  detail  in the
accompanying Joint Proxy  Statement/Prospectus. Please review  and consider  the
enclosed materials carefully.

    For    the   reasons   set   forth   in   the   accompanying   Joint   Proxy
Statement/Prospectus, your Board of Directors  believes that the Merger is  fair
to,  and in the  best interests of,  the stockholders of  Horizon and recommends
that you vote  in favor of  approval and  adoption of the  Merger Agreement.  In
making that determination, the Board of Directors received and took into account
the  opinion dated March 31, 1995  of Salomon Brothers Inc ("Salomon Brothers"),
an investment banking  firm retained by  Horizon for that  purpose, that, as  of
such date, the consideration to be paid by Horizon in the Merger was fair to the
stockholders  of  Horizon  from  a financial  point  of  view.  Salomon Brothers
subsequently delivered its written  opinion dated the date  of this Joint  Proxy
Statement/Prospectus (the "Salomon Brothers Opinion") that, as of such date, the
consideration  to be paid by Horizon in  the Merger was fair to the stockholders
of Horizon  from a  financial point  of view.  A copy  of the  Salomon  Brothers
Opinion  is  included in  the accompanying  Joint Proxy  Statement/Prospectus as
Appendix B thereto.

    At the Special Meeting, stockholders will also be asked to approve,  subject
to  consummation of  the transactions contemplated  by the  Merger Agreement, an
amendment to Horizon's Restated Certificate of Incorporation to change Horizon's
name to Horizon/CMS Healthcare Corporation upon the effectiveness of the Merger.

    If you  have any  questions prior  to the  Special Meeting  or need  further
assistance,  please  call Georgeson  & Company  Inc., who  will be  assisting in
connection with the Special Meeting, at (800) 223-2064.

    Whether or not  you plan to  be at the  Special Meeting, please  be sure  to
sign,  date and  return the  enclosed proxy  or voting  instruction card  in the
enclosed envelope as promptly as possible so that your shares may be represented
at the Special Meeting and  voted in accordance with  your wishes. Your vote  is
important regardless of the number of shares you own.

                                          Sincerely,

       effectiveness of the Merger; and

    3.  To transact such other business as may properly come before the  Horizon
       Special Meeting or any adjournment thereof.

    The  Board of Directors has  fixed the close of business  on May 19, 1995 as
the record date for the determination of stockholders entitled to notice of, and
to vote at, the Horizon Special Meeting or any adjournment thereof. Only holders
of record of  shares of Horizon  Common Stock at  the close of  business on  the

To Our Stockholders:

    You are cordially invited to attend a Special Meeting of Stockholders to  be
held  at 11:00  a.m., local  time, on  Thursday, July  6, 1995  at the executive
offices of  Continental  Medical  Systems,  Inc. ("CMS")  at  600  Wilson  Lane,
Mechanicsburg, Pennsylvania (the "Special Meeting").

    At  the  Special Meeting,  you will  be asked  to consider  and vote  upon a
proposal to approve  and adopt the  Amended and Restated  Agreement and Plan  of
Merger  dated as  of May  23, 1995  (the "Merger  Agreement") providing  for the
merger (the  "Merger")  of  a  wholly owned  subsidiary  of  Horizon  Healthcare
Corporation  into CMS. Under the terms of the Merger Agreement, each outstanding
share of CMS common stock would be  converted into .5397 shares of common  stock
of Horizon Healthcare Corporation and CMS would become a wholly owned subsidiary
of  Horizon. Horizon  will thereupon change  its name  to Horizon/CMS Healthcare
Corporation.

    The Board of Directors of CMS has  received an opinion dated March 31,  1995
from  its financial advisor, Merrill Lynch,  Pierce, Fenner & Smith Incorporated
("Merrill Lynch"), that, as of such date, the exchange ratio contemplated by the
Merger Agreement was fair to the stockholders  of CMS from a financial point  of
view. Merrill Lynch subsequently delivered its written opinion dated the date of
this  Joint Proxy Statement/Prospectus (the "Merrill Lynch Opinion") that, as of
such date,  the Exchange  Ratio  was fair  to the  stockholders  of CMS  from  a
financial  point of  view. A copy  of the  Merrill Lynch Opinion  is included as
Appendix C to the Joint Proxy Statement/Prospectus.

    For   the   reasons   set   forth   in   the   accompanying   Joint    Proxy
Statement/Prospectus,  your Board of Directors believes  that the Merger is fair
to and in the best  interests of CMS and  its stockholders, and recommends  that
stockholders vote FOR approval and adoption of the Merger Agreement.

    The  Merger Agreement,  the Merrill  Lynch Opinion  and financial  and other
information concerning the  business of Horizon  Healthcare Corporation and  CMS
are included in the enclosed Joint Proxy Statement/Prospectus. Please review the
Joint Proxy Statement/Prospectus carefully.

    If  you have  any questions  prior to  the Special  Meeting or  need further
assistance, please call  Corporate Investor  Communications, Inc.,  who will  be
assisting in connection with the Special Meeting, at (800) 242-4410.

    The  affirmative vote of the holders of a majority of the outstanding shares
of CMS common stock is  required to approve and  adopt the Merger Agreement,  so
failure  to  vote  will  have the  same  effect  as a  vote  against  the Merger
Agreement. Accordingly, we  urge you  to complete,  sign and  date the  enclosed
proxy  or voting instruction card and return it in the enclosed return envelope,
whether or  not  you  plan  to  attend the  meeting.  Your  vote  is  important,
regardless of the number of shares you own.

                                          Sincerely,

    TERMS OF THE MERGER.  At the Effective Time (as hereinafter defined), Merger
Sub  will merge with and into CMS,  with CMS being the surviving corporation and
becoming a wholly owned subsidiary of Horizon (the "Surviving Corporation").  In
the  Merger, each share  of CMS Common  Stock outstanding at  the Effective Time
(other than  shares held  directly or  indirectly  by Horizon  or CMS)  will  be
converted into .5397 shares of Horizon Common Stock (the "Exchange Ratio").

                                       6
<PAGE>
    Based  on the number of shares of  Horizon Common Stock and CMS Common Stock
outstanding as of the record dates for  the Horizon Special Meeting and the  CMS
Special  Meeting, 20,849,844  shares of  Horizon Common  Stock will  be issuable
pursuant to the Merger  Agreement (assuming no issuance  prior to the  Effective
Time  of CMS Common Stock upon exercise of CMS Options or the CMS Warrants, upon
conversion of  the CMS  Convertible Debenture  or pursuant  to the  CMS  Earnout
Agreements), representing approximately 41% of the total Horizon Common Stock to
be outstanding after such issuance.

    RECOMMENDATION  OF THE HORIZON BOARD OF DIRECTORS. THE BOARD OF DIRECTORS OF
HORIZON HAS DETERMINED THAT THE MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF,
THE STOCKHOLDERS  OF HORIZON  AND RECOMMENDS  THAT THE  STOCKHOLDERS OF  HORIZON
APPROVE  THE  ISSUANCE  AND RESERVATION  FOR  ISSUANCE OF  HORIZON  COMMON STOCK
PURSUANT TO THE TERMS  OF THE MERGER AGREEMENT  AND APPROVE THE HORIZON  CHARTER
AMENDMENT.

    Management  of  Horizon believes  that the  Merger would  create one  of the
nation's major post-acute care companies  and the largest specialty health  care
providers.  In the course of its evaluation  of the proposed Merger, the Horizon
Board of  Directors considered  the numerous  positive factors  set forth  under
"Horizon's  Reasons  for the  Merger; Recommendation  of  Board of  Directors of
Horizon". In  addition,  it  considered  certain factors  that  it  regarded  as
negative.   Those  negative  factors,  which  are  more  fully  described  under
"Horizon's Reasons for the Mergers; Recommendation of the Board of Directors  of
Horizon,"  were anticipated  dilution of  up to  10% in  Horizon's projected net
income per  share for  fiscal 1995,  the financial  performance of  and  special
charges  recorded by CMS for  the fiscal years 1993 and  1994 and the six months
ended December 31, 1994 and certain  regulatory matters regarding CMS. Based  on
the  total mix  of information  available to it,  however, the  Horizon Board of
Directors unanimously approved the Merger Agreement and recommended its approval
to the stockholders of Horizon.

    RECOMMENDATION OF CMS BOARD OF DIRECTORS.  THE BOARD OF DIRECTORS OF CMS HAS
DETERMINED THAT  THE MERGER  IS  FAIR TO,  AND IN  THE  BEST INTERESTS  OF,  THE
STOCKHOLDERS  OF CMS  AND RECOMMENDS  THAT THE  STOCKHOLDERS OF  CMS APPROVE AND
ADOPT THE MERGER AGREEMENT.  See "The Merger --  Background" and "CMS's  Reasons
for the Merger; Recommendation of the Board of Directors of CMS." In considering
the recommendation of the CMS Board with respect to the Merger, CMS stockholders
should  be  aware  that  certain  officers and  directors  of  CMS  have certain
interests respecting the Merger, apart  from their interests as stockholders  of
CMS. See "The Merger -- Interests of Certain Persons in the Merger."

    OPINIONS  OF FINANCIAL ADVISORS.   Salomon Brothers Inc ("Salomon Brothers")
has delivered its written opinion dated March 31, 1995 to the Board of Directors
of Horizon that, as of such date, the consideration to be paid by Horizon in the
Merger was fair to the holders of Horizon Common Stock from a financial point of
view. Merrill Lynch, Pierce, Fenner  & Smith Incorporated ("Merrill Lynch")  has
delivered  its written opinion dated March 31, 1995 to the Board of Directors of
CMS that,  as  of such  date,  the exchange  ratio  contemplated by  the  Merger
Agreement  was fair to the  stockholders of CMS from  a financial point of view.
Salomon Brothers subsequently delivered  its written opinion  dated the date  of
this  Joint Proxy Statement/Prospectus (the "Salomon Brothers Opinion") that, as
of such date, the consideration to be paid by Horizon in the Merger was fair  to
the  holders of  Horizon Common  Stock from a  financial point  of view. Merrill
Lynch subsequently delivered its  written opinion dated the  date of this  Joint
Proxy  Statement/Prospectus (the "Merrill Lynch Opinion") that, as of such date,
the Exchange Ratio was fair to the stockholders of CMS from a financial point of
view.

    For information regarding the Salomon Brothers Opinion and the Merrill Lynch
Opinion, including  the assumptions  made  and matters  considered in,  and  the
limitations  on, the review undertaken by  Salomon Brothers and Merrill Lynch as
set forth in their respective opinions, see "The Merger -- Opinions of Financial
Advisors." Stockholders of Horizon and CMS  are urged to read in their  entirety
the  Salomon  Brothers  Opinion  and  the  Merrill  Lynch  Opinion,  attached as
Appendices B and C, respectively, to this Joint Proxy Statement/Prospectus.

EFFECTIVE TIME OF THE MERGER

    The Merger will become effective upon the filing of a certificate of  merger
with  the Secretary of  State of the  State of Delaware  (the "Effective Time"),
unless the certificate of merger specifies a later Effective Time. Assuming  all
conditions  to the Merger contained in the Merger Agreement are satisfied or, to
the extent susceptible to waiver, waived  prior thereto, it is anticipated  that
the Effective Time of the Merger will occur as soon as practicable following the
Horizon and CMS Special Meetings.

CERTAIN CONDITIONS TO THE CONSUMMATION OF THE MERGER

    The obligations of both Horizon and CMS to consummate the Merger are subject
to the satisfaction of certain conditions, including the following: (i) approval
by  the stockholders of Horizon of the issuance of Horizon Common Stock pursuant
to the Merger Agreement,  and approval and adoption  of the Merger Agreement  by
the stockholders of CMS; (ii) the absence of any order making the Merger illegal
or  otherwise prohibiting consummation of the  Merger; (iii) Horizon having been
advised in writing by Arthur Andersen LLP that the Merger should be treated  for
financial  accounting purposes as a "pooling of interests;" and (iv) the absence
of certain  regulatory conditions.  None  of the  foregoing conditions  will  be
waived by either Horizon or CMS. In addition, the obligations of each of Horizon
and CMS are subject to the accuracy of the representations and warranties of the
other  party and to compliance with all  agreements and covenants on the part of
the other party  contained in the  Merger Agreement. Either  Horizon or CMS  may
extend the time for performance of any of the obligations of the other party or,
except  as aforesaid, waive compliance with those obligations at its discretion.
See "Certain Terms of the Merger Agreement -- Conditions to the Merger".

    Horizon and CMS anticipate that all of the conditions to the consummation of
the Merger (other than receipt of the required approvals of the stockholders  of
Horizon  and CMS)  will be  satisfied prior  to or  at the  time of  the Horizon
Special Meeting and the CMS Special Meeting.

GOVERNMENTAL APPROVALS

    On April 20,  1995, Horizon and  CMS each filed  a notification and  report,
together  with requests for  early termination of the  waiting period, under the
Hart-Scott-Rodino Antitrust  Improvements  Act of  1976,  as amended  (the  "HSR
Act"),  with  the Federal  Trade Commission  and the  Antitrust Division  of the
Department of Justice in respect of the Merger. Expiration or early  termination
of  the  applicable waiting  period  under the  HSR Act  is  a condition  to the
obligations of Horizon and CMS  to consummate the Merger.  On May 20, 1995,  the
applicable  waiting period  expired with  no request  for additional information
having been made.

   
    Horizon and CMS have provided the appropriate regulatory authorities in  all
of  the states in which CMS  operates rehabilitation hospitals with any required
notices, disclosures and/or  applications for determination  of need  consistent
with  applicable licensure and/or  certificate of need  statutory and regulatory
provisions. On  June  2, 1995,  the  Commonwealth of  Massachusetts  issued  its
determination  of need in respect of the  Merger. Virtually all of the remaining
states in  which  CMS  operates rehabilitation  hospitals  have  concurred  with
Horizon's  and CMS's view that the proposed  Merger does not constitute a change
of ownership for  either licensure  or certificate  of need  purposes. See  "The
Merger  -- Governmental and  Regulatory Approvals and  Matters." Neither Horizon
nor CMS is aware of any  other governmental or regulatory approval required  for
consummation  of the  Merger, other  than compliance  with applicable securities
laws.

NO SOLICITATION

    The Merger  Agreement  provides  that  CMS will  not  initiate,  solicit  or
encourage  (including  by  way  of  furnishing  information  or  assistance) any
inquiries or the making  of any proposal relating  to any Competing  Transaction
(as defined below), or enter into discussions or negotiations with any person in
furtherance  of a  Competing Transaction, or  agree to, or  endorse, a Competing
Transaction; PROVIDED, HOWEVER, that CMS  may furnish information or enter  into
discussions or negotiations with respect to an unsolicited bona fide proposal in
writing  relating to a Competing Transaction  for which financing, to the extent
required, is then committed (except that a financing commitment is not  required
for  purposes of furnishing information only), if,  and only to the extent that,
the Board  of Directors  of CMS,  after  consultation with  and based  upon  the
written  advice of  outside legal  counsel, determines  in good  faith that such
action is  required  for such  Board  to comply  with  its fiduciary  duties  to
stockholders  imposed by  the DGCL. CMS  is required to  provide Horizon written
notice prior to taking any such actions,  to notify Horizon of any inquiries  or
proposals  received  by CMS  and to  provide  copies of  any written  inquiry or
proposal. Further, the Board  of Directors of CMS  may determine not to  solicit
proxies  in favor of the  approval and adoption of  the Merger Agreement if such
Board determines in  good faith after  consultation with legal  counsel and  its
financial  advisors that other  action is necessary  due to applicable fiduciary
duties of the  directors of  CMS. A  "Competing Transaction"  means any  merger,
consolidation,  share  exchange,  business  combination  or  similar transaction
involving CMS or any of its  Significant Subsidiaries (as defined in the  Merger
Agreement)  or  the acquisition  in  any manner,  directly  or indirectly,  of a
material interest in any voting securities of, or a material equity interest  in
a  substantial  portion  of  the  assets  of,  CMS  or  any  of  its Significant
Subsidiaries, other than the transactions contemplated by the Merger  Agreement.
See "Certain Terms of the Merger Agreement -- No Solicitation."

TERMINATION OF THE MERGER AGREEMENT

    GENERAL.   The Merger Agreement  may be terminated at  any time prior to the
Effective Time (i) by mutual consent of Horizon and CMS or (ii) by either  party
if  (a) the Merger has  not been consummated on or  before December 31, 1995 (or
March 31, 1996, if  the Merger shall  not have been consummated  as a result  of
either  party  having  failed  by  December 31,  1995  to  receive  all required
regulatory approvals or  consents with  respect to  the Merger),  (b) any  final
court  or governmental order shall have prohibited consummation of the Merger or
(c) the  required  approvals of  the  stockholders of  Horizon  or CMS  are  not
received at the applicable meeting of stockholders.

    BY HORIZON.  Horizon may terminate the Merger Agreement (i) upon a breach of
any  material representation, warranty, covenant or agreement on the part of CMS
set forth in the Merger Agreement or the Stock Option Agreement, or if any  such
representation  or warranty shall  have become untrue, in  either case such that
Horizon's conditions  to closing  of  the Merger  would  be incapable  of  being
satisfied,  or (ii)  if the  Board of  Directors of  CMS withdraws,  modifies or
changes its  recommendation of  the Merger  in a  manner adverse  to Horizon  or
recommends  to the stockholders of CMS  any Competing Transaction or resolves to
do so, or (iii) if a tender or exchange offer for 20% or more of the outstanding
CMS Common  Stock is  commenced, and  the Board  of Directors  of CMS  does  not
recommend  that stockholders not tender their shares into such offer, or (iv) if
any person (other than Horizon or its  affiliates) acquires or has the right  to
acquire  beneficial  ownership of,  or  any group  shall  have been  formed that
beneficially owns, or has the right  to acquire beneficial ownership of, 20%  or
more of the outstanding CMS Common Stock.

    BY  CMS.  CMS  may terminate the Merger  Agreement (i) upon  a breach of any
material representation, warranty, covenant or agreement on the part of  Horizon
set  forth in the  Merger Agreement, or  if any such  representation or warranty
shall have become untrue, in either  case such that CMS's conditions to  closing
of  the Merger  would be incapable  of being satisfied,  or (ii) if  a tender or
exchange offer  for 20%  or more  of  the outstanding  Horizon Common  Stock  is
commenced,  and  the  Board of  Directors  of  Horizon does  not  recommend that
stockholders not tender  their shares into  such offer, or  (iii) if any  person
acquires or has the right to acquire beneficial ownership of, or any group shall
have  been formed that beneficially owns, or has the right to acquire beneficial
ownership of, 20% or more of

                                       9
<PAGE>
the outstanding Horizon Common Stock, or (iv) if CMS accepts a bona fide written
proposal relating  to  a  Competing  Transaction on  terms  that  the  Board  of
Directors  of CMS determines that it cannot reject in favor of the Merger, based
upon applicable  fiduciary duties  and  the advice  of  counsel, and  for  which
financing, to the extent required, is then committed (a "Superior Proposal").

    See  "Certain Terms of  the Merger Agreement --  Termination or Amendment of
the Merger Agreement."

TERMINATION FEES

    If the Merger Agreement is terminated upon the occurrence of certain of  the
events  described  above, CMS  will be  required  to pay  to Horizon  an amount,
subject to certain  limitations, equal  to $20 million  plus Horizon's  expenses
incurred  in  connection  with  the  transactions  contemplated  by  the  Merger
Agreement, not to exceed $5 million. In addition, under those circumstances, the
Stock Option granted by CMS to Horizon to acquire up to 5,793,567 shares of  CMS
common  stock would  become exercisable. If  the Merger  Agreement is terminated
upon the occurrence  of certain other  events described above,  Horizon will  be
required  to pay CMS  a termination fee  of $10 million.  See "-- Stock Option;"
"Stock Option Agreement;" "Certain Terms of the Merger Agreement -- Expenses and
Termination Fees."

ASSUMPTION OF CMS OPTIONS AND OTHER OBLIGATIONS

    As of the Effective Time, Horizon  will assume each CMS Option that  remains
unexercised  in whole or in part. Accordingly, each CMS Option will be deemed to
remain outstanding as an option to purchase, in lieu of the shares of CMS Common
Stock previously subject thereto, that number of shares of Horizon Common  Stock
equal  to the product of the number of shares of CMS Common Stock subject to the
CMS Option multiplied  by the Exchange  Ratio. The exercise  price per share  of
Horizon  Common Stock  will be  equal to the  previous exercise  price per share
under the CMS Option divided  by the Exchange Ratio.  See "Certain Terms of  the
Merger Agreement -- Assumption of Obligations to Issue CMS Common Stock."

    In  addition, Horizon has agreed  in the Merger Agreement  to assume, at the
Effective Time,  the obligations  of CMS  with respect  to the  issuance of  CMS
Common  Stock under  the CMS  Warrants, the  CMS Debenture  and the  CMS Earnout
Agreements by agreeing  to issue  in lieu thereof  Horizon Common  Stock on  the
basis  described under "Certain  Terms of the Merger  Agreement -- Assumption of
Obligations to Issue CMS  Common Stock." Assuming that  no shares of CMS  Common
Stock  are issued prior to the Effective Time  on exercise of any CMS Options or
any of the CMS Warrants, on conversion  of the CMS Debenture or pursuant to  the
CMS  Earnout Agreements,  Horizon will  be required  to reserve  for issuance an
aggregate of 4,394,818 shares of Horizon Common Stock for such purposes. Of such
shares, 3,917,916 will be reserved in connection with CMS Options, 188,895  will
be  reserved in connection  with the CMS  Warrants, 126,097 will  be reserved in
connection with the  CMS Debenture and  161,910 will be  reserved in  connection
with the CMS Earnout Agreements.

HORIZON BOARD OF DIRECTORS

    Prior  to the Merger, Horizon will expand  its Board of Directors from eight
to 13 positions, and will ensure that the five newly created directorships  will
be filled with individuals designated by CMS. At least one of such CMS designees
will  serve on  each of  the Horizon  Audit Committee,  the Horizon Compensation
Committee and the Horizon Executive Committee (subject to their determination to
not serve).

INDEMNIFICATION

    The Merger Agreement  provides that,  for a period  of six  years after  the
Effective Time, Horizon (i) will not amend certain indemnification and liability
limitation  provisions  of  CMS's  charter  or bylaws  in  a  manner  that would
adversely affect the rights of individuals who were officers or directors of CMS
and (ii) will  cause to  be maintained in  effect CMS's  current directors'  and
officers'  liability  insurance, subject  to  certain limitations.  See "Certain
Terms of the Merger Agreement -- Indemnification."

<PAGE>
                                  STOCK OPTION

    Horizon and CMS  have entered into  a Stock Option  Agreement in  connection
with,  and as  consideration for,  Horizon's and  Merger Sub's  execution of the
Merger Agreement. Under the Stock Option  Agreement, CMS has granted to  Horizon
an  irrevocable option  to purchase up  to 5,793,567 shares,  subject to certain
adjustments, of CMS  Common Stock  for an exercise  price of  $13.00 per  share,
subject  to certain adjustments, which option is exercisable in whole or in part
and from time to time after  the Merger Agreement becomes terminable by  Horizon
under  circumstances that  would, if the  Merger Agreement were  terminated as a
result thereof,  entitle Horizon  to payment  of the  termination fee  described
above. See "Certain Terms of the Merger Agreement -- Termination or Amendment of
the Merger Agreement" and "Stock Option Agreement."

                                VOTING AGREEMENT

    Pursuant  to the  Voting Agreement,  Rocco A.  Ortenzio, Chairman  and Chief
Executive Officer  of CMS,  Robert A.  Ortenzio, President  and Chief  Operating
Officer  of CMS, and certain corporations  controlled by them have agreed, among
other things, to vote all shares of CMS  Common Stock owned by them in favor  of
the  Merger Agreement.  As of  the CMS  Record Date,  approximately 8.9%  of the
outstanding shares of CMS Common Stock were subject to the Voting Agreement. See
"Voting Agreement."

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES

    The Merger is intended to qualify  as a reorganization under Section  368(a)
of  the Internal  Revenue Code  of 1986,  as amended  (the "Code"),  and should,
therefore, constitute a non-taxable transaction for Horizon, CMS and the holders
of CMS Common Stock, except to the extent  of cash received, if any, in lieu  of
fractional  shares of Horizon Common Stock. For  a discussion of these and other
federal income tax considerations in connection with the Merger, see "The Merger
- -- Certain Federal Income Tax Consequences."

                        ANTICIPATED ACCOUNTING TREATMENT

    The Merger is expected to be accounted  for as a "pooling of interests"  for
financial accounting purposes. See "The Merger -- Accounting Treatment."

                              NO APPRAISAL RIGHTS

    Under  Delaware  law,  neither  Horizon's  nor  CMS's  stockholders  will be
entitled to any appraisal or dissenter's  rights in connection with the  Merger.
See "The Merger -- Rights of Dissenting Stockholders."

                   EXCHANGE OF CMS COMMON STOCK CERTIFICATES

    Promptly  after consummation  of the Merger,  Horizon will mail  a letter of
transmittal with  instructions to  each holder  of record  of CMS  Common  Stock
outstanding  immediately  before  the  Effective  Time  for  use  in  exchanging
certificates formerly representing shares of  CMS Common Stock for  certificates
representing  shares of Horizon Common Stock and  cash in lieu of any fractional
shares. Certificates should  not be  surrendered by  the holders  of CMS  Common
Stock  until  they have  received the  letter of  transmittal from  Horizon. See
"Certain Terms  of  the Merger  Agreement  --  Manner and  Basis  of  Converting
Shares."

                   INTERESTS OF CERTAIN PERSONS IN THE MERGER

    At  the  Effective Time,  Rocco A.  Ortenzio,  Chairman and  Chief Executive
Officer of  CMS, will  become Vice  Chairman of  Horizon's Board  of  Directors.
Immediately  following  that  time,  in satisfaction  of  his  rights  under his
existing  employment   arrangements   with   CMS,  he   will   receive   certain

                                       11
<PAGE>
payments  aggregating $15.3 million and his  employment with CMS will cease. Mr.
Ortenzio has agreed,  following the  Merger, to provide  consulting services  to
Horizon  on an hourly  basis at a  rate of $300  per hour. Of  the $15.3 million
payment, $3.7 million represents  a contractual payment  due Mr. Ortenzio  under
the  terms of his  employment agreement with CMS  upon termination without cause
after a change in control  of CMS, up to $0.6  million represents payment for  a
non-competition  agreement, and the balance represents a payment to Mr. Ortenzio
in satisfaction of  his contractual  right to  receive an  annual bonus  payment
equal  to three percent  of CMS's consolidated pre-tax  profits (as adjusted) in
excess of $2.5 million per fiscal year  until the expiration of the term of  his
employment  agreement in 1998. The present  value of Mr. Ortenzio's future bonus
payments was  determined  by projecting  the  future operating  results  of  CMS
through  the remaining term of his employment  agreement and was confirmed by an
independent benefits consultant. The payment for terminating the annual bonus is
capped at $11.6  million less  any amounts to  be paid  under a  non-competition
agreement.  Robert A.  Ortenzio, President and  Chief Operating  Officer of CMS,
will at  the  same time  become  a director  and  enter into  a  new  employment
agreement with Horizon initially at his current salary level. See "The Merger --
Employment Arrangements."

    Following  the Merger,  the other senior  executive officers of  CMS will be
entitled to  certain payments  if their  employment is  subsequently  terminated
under  certain  circumstances pursuant  to their  previously existing  change in
control agreements with CMS in the following approximate amounts: Frank Fritsch,
$595,000; Dennis Lehman,  $595,000; David Nation,  $650,000; and Patricia  Rice,
$395,000.  See  "The  Merger  -- Employment  Arrangements."  Under  the proposed
Merger, Mr. Neal M. Elliott, Chairman of the Board, Chief Executive Officer  and
President of Horizon will receive approximately 5,397 shares of Horizon Stock on
account  of his ownership of 10,000 shares  of CMS Common Stock. See "The Merger
- -- Interests of Certain Persons in the Merger."

    Certain members of the Boards of Directors and management of CMS and Horizon
have  certain  additional  interests  respecting  the  Merger,  including  those
referred  to above in this Summary under "-- The Merger and the Merger Agreement
- -- Horizon Board  of Directors"  and "--  Indemnification." See  "The Merger  --
Board Arrangements" and "The Merger -- Employment Arrangement."

               COMPARATIVE RIGHTS OF CMS AND HORIZON STOCKHOLDERS

    Rights  of  stockholders of  CMS  are currently  governed  by the  DGCL, the
Restated Certificate of Incorporation,  as amended, of  CMS (the "CMS  Charter")
and  CMS's By-Laws,  as amended  (the "CMS  By-Laws"). Upon  consummation of the
Merger, CMS stockholders will become stockholders of Horizon and their rights as
stockholders of Horizon will be governed  by the DGCL, the Restated  Certificate
of  Incorporation, as amended, of Horizon  (the "Horizon Charter") and Horizon's
Amended and  Restated  Bylaws, as  amended  (the "Horizon  Bylaws").  There  are
certain  differences between  the rights of  CMS stockholders and  the rights of
Horizon stockholders. See "Comparative Rights  of Horizon and CMS  Stockholders"
and "Description of Horizon Capital Stock."

                             SPECIAL CONSIDERATIONS

    The  stockholders of Horizon  and CMS should  consider the factors discussed
under "Special Considerations" in evaluating  the Merger. Those factors  include
(i)  the  risks associated  with  Horizon's expansion  and  development program,
including the risk that  acquired operations could  be subject to  unanticipated
business   uncertainties  or   legal  liabilities,   the  risk   that  currently
unanticipated difficulties  may  arise  in  the  integration  of  operations  of
combining  business  entities  and  the  risk  that  anticipated  synergies from
business combinations may not be realized; (ii) the uncertainties created by the
promulgation by  the  Health  Care  Financing  Administration  of  a  memorandum
relating  to  nonbinding rates  guidelines for  speech and  occupational therapy
costs reimbursement of inpatient providers;  (iii) the reliance of both  Horizon
and  CMS on Medicaid and Medicare programs  as payor sources; (iv) the extensive
regulation of the  businesses of  Horizon and CMS  by federal,  state and  local
governments;  (v) health care  reform proposals intended  to control health care
costs, to improve  access to  medical services and  to assist  in balancing  the
federal budget; (vi) the risks imposed on the

                                       12
<PAGE>
businesses  of Horizon  and CMS  with respect  to medical  malpractice, personal
injury and  other  liability claims  and  the insurance  coverage  with  respect
thereto;  (vii) the dependency  of both Horizon  and CMS on  the availability of
competent, trained and experience personnel  in marketing, nursing, therapy  and
certain  other discplines; (viii) the dependency  of Horizon on a limited number
of  key  officers;   and  (ix)  the   antitakeover  implications  of   Horizon's
stockholders  rights plan and  certain provisions of its  charter and bylaws. In
addition,  Horizon  stockholders  should   consider  certain  negative   factors
evaluated  by the Horizon Board of Directors in its consideration of the Merger,
including anticipated dilution of up to 10% in Horizon's pro forma combined  net
income  per  share for  fiscal 1995,  the financial  performance of  and special
charges recorded by CMS  in the fiscal  years 1993 and 1994  and the six  months
ended  December  31,  1994 and  certain  regulatory matters  involving  CMS. CMS
stockholders should consider the fact that  the Exchange Ratio is fixed and  the
market  price of  the Horizon  Common Stock is  subject to  fluctuation based on
market influences, most of which are beyond the control of Horizon.

                               MARKET PRICE DATA

    Horizon Common Stock is traded  on the NYSE under  the symbol "HHC" and  CMS
Common  Stock is traded on the NYSE  under the symbol "CNM." The following table
sets forth, for the periods indicated, the range of high and low per share sales

                            HORIZON DIVIDEND POLICY

    Horizon has not paid or declared any dividends on Horizon Common Stock since
its inception and anticipates that future  earnings will be retained to  finance
the  continuing development of its business. The payment of any future dividends
will be at the discretion of Horizon's Board of Directors and will depend  upon,
among   other  things,  future  earnings,  the  success  of  Horizon's  business
activities, regulatory and capital requirements, the general financial condition
of Horizon  and  general  business conditions.  In  addition,  Horizon's  credit
facility restricts the payment of dividends.

                             SPECIAL CONSIDERATIONS

    The  following  are  certain  factors  which  should  be  considered  by the
stockholders of Horizon and CMS in evaluating the Merger.

   
    FACTORS SPECIFICALLY  AFFECTING  HORIZON  STOCKHOLDERS.__Among  the  factors
considered  by  the Board  of  Directors of  Horizon  in the  evaluation  of the
proposed Merger were certain negative factors. Those negative factors, which are
more fully described  under "The  Merger --  Horizon's Reasons  for the  Merger;
Recommendation  of  the Board  of Directors  of  Horizon," were  (i) anticipated
dilution of up to 10% in Horizon's  pro forma combined net income per share  for
fiscal  1995, (ii) the financial performance  of and special charges recorded by
CMS for the fiscal  years 1993 and  1994 and the six  months ended December  31,
1994 and (iii) certain regulatory matters regarding CMS.
    

   
    FACTORS SPECIFICALLY AFFECTING CMS STOCKHOLDERS.__Because the Exchange Ratio
is  fixed and  because the market  price of  Horizon Common Stock  is subject to
fluctuation, the market value of the shares of Horizon Common Stock that holders
of CMS Common Stock will receive in the Merger may increase or decrease prior to
and following  the Merger.  There  can be  no assurance  that  at or  after  the
Effective  Time of the Merger such shares  of Horizon Common Stock will maintain
or equal the prices at which such shares have traded in the past. The prices  at
which  Horizon Common Stock  trades after the  Merger may be  influenced by many
factors, including, among others, the liquidity of the market for Horizon Common
Stock, investor perceptions of  Horizon and the industry  in which it  operates,
the operating results of Horizon and its subsidiaries, Horizon's dividend policy
and general economic and market conditions. Similar factors affect the prices at
which CMS Common Stock currently trades. See "Summary -- Market Price Data."
    

   
    Among  the  factors considered  by  the Board  of  Directors of  CMS  in the
evaluation of the proposed Merger were certain negative factors. Those  negative
factors,  which are more fully described under  "The Merger -- CMS's Reasons for
the Merger; Recommendation of the Board of Directors of CMS," were (i) the rapid
growth of Horizon through  a number of relatively  recent acquisitions and  that
such  acquisitions may  not have been  fully integrated into  Horizon, (ii) that
currently unanticipated difficulties could arise in integrating the operation of
Horizon and CMS, (iii) that the synergies expected from combining the operations
of CMS and Horizon may not be realized and (iv) Horizon's greater dependence  on
Medicaid-based revenues and the risks associated with regulatory changes in that
area.
    

    ACQUISITIONS  AND  EXPANSION.   Since  its  inception in  1986,  Horizon has
rapidly expanded  its  operations  through the  acquisition  of  long-term  care
facilities  as  well  as  through the  development  of  specialty  hospitals and
subacute care units. Growth  through acquisition entails  certain risks in  that
acquired  operations could be subject to unanticipated business uncertainties or
legal liabilities. Horizon seeks to  minimize these risks through  investigation
and evaluation of the operations proposed to be acquired and through transaction
structure and indemnification. The various risks associated with the operational
integration  of  future  acquisitions  and the  subsequent  performance  of such
acquired operations may  adversely affect  Horizon's results  of operations.  In
addition,  the ability of Horizon to  acquire additional operations depends upon
its ability to obtain appropriate financing and personnel.

    In addition, each such business combination presents the risk that currently
unanticipated difficulties  may  arise  in integrating  the  operations  of  the
combined  entities.  This  is  particularly  true  in  the  case  of  a business
combination of two major corporations, such  as Horizon and CMS. Moreover,  such
business  combinations present  the risk  that the  synergies expected  from the
combined operations may  not be  realized. For  a description  of the  synergies
which  management of Horizon anticipates to  be realized from the combination of
Horizon  and  CMS,  see  "The  Merger  --  Horizon's  Reasons  for  the  Merger;
Recommendation of Horizon Board of Directors."

    REIMBURSEMENT  RATES  FOR CONTRACT  THERAPY SERVICES.    In April  1995, the
Health Care  Financing  Administration  ("HCFA")  issued  a  memorandum  to  its
Medicare  fiscal intermediaries  as guidelines  for assessing  costs incurred by
inpatient providers  relating to  payment of  occupational and  speech  language
pathology  services furnished under arrangements  that include contracts between
therapy

                                       21
<PAGE>
providers  and   inpatient  providers.   While  not   binding  on   the   fiscal
intermediaries,  the  memorandum suggested  certain rates  to assist  the fiscal
intermediaries in  making  annual  "prudent buyer"  assessments  of  speech  and
occupational  therapy rates paid  by inpatient providers. In  light of the fluid
nature of the circumstances surrounding the memorandum, neither Horizon nor  CMS
can now determine whether HCFA will continue to recommend the rates suggested in
the  memorandum  or whether  such rates  will be  used  by HCFA  as a  basis for
developing a  salary  equivalency  based reimbursement  system  for  speech  and
occupational therapy services. For more information with respect to this matter,
see  "The  Merger  --  Governmental  and  Regulatory  Approvals  and  Matters --
Reimbursement Rates for Contract Therapy Services."

    REIMBURSEMENT BY THIRD PARTY PAYORS.  For fiscal years 1992, 1993, and 1994,
Horizon derived approximately 62%,  56% and 46%,  respectively, of its  revenues
from  Medicaid (excluding certain out-of-state  Medicaid revenues), and 12%, 15%
and 19%, respectively, from  Medicare. During the  comparable fiscal years,  CMS
derived approximately 3%, 3% and 2%, respectively, of its revenues from Medicaid
and  39%,  38% and  40%,  respectively, from  Medicare.  Changes in  the  mix of
patients among Medicaid, private  pay sources and Medicare  and with respect  to
different types of private pay sources can significantly affect the revenues and
profitability  of  both  Horizon's  and CMS's  operations.  Moreover,  there are
increasing pressures from many payor sources to control health care costs and to
limit increases in  reimbursement rates for  medical services. There  can be  no
assurance  that payments under governmental and  third party payor programs will
remain at  levels comparable  to present  levels or  that Horizon  and CMS  will
continue  to attract and  retain private pay patients  or maintain their current
payor or revenue mixes. In attempts  to limit the federal budget deficit,  there
have  been, and Horizon and CMS expect that  there will continue to be, a number
of proposals to limit Medicare and Medicaid reimbursement for certain  services.
Neither  Horizon nor CMS can predict whether any of these pending proposals will
be adopted or, if adopted and implemented, what effect such proposals would have
on Horizon, CMS or the combined enterprise.

    REGULATION.  The federal government and  all states in which Horizon or  CMS
operates  regulate various aspects of their  respective businesses. There can be
no assurance  that  federal or  state  governments will  not  impose  additional
restrictions  on their activities that  might adversely affect their businesses.
The operation of Horizon's long-term care facilities and certain segments of its
specialty health care services and the  provision of these services, as well  as
certain  aspects of the business of CMS, are subject to federal, state and local
licensure and certification laws. Long-term care facilities and certain segments
of Horizon's  specialty  health  care  services,  as  well  as  certain  of  the
operations  of CMS, are subject to periodic inspection by governmental and other
authorities to  assure compliance  with the  various standards  established  for
continued  licensure  under  state  law, certification  under  the  Medicare and
Medicaid programs and participation in the Veteran's Administration program. The
failure by either Horizon  or CMS to obtain  or retain such approvals,  licenses
and   certifications  could  adversely  affect   its  operations  and  financial
performance. To the extent that Certificates of Need or other similar  approvals
are  required for  expansion of  Horizon's or  CMS's operations,  Horizon or CMS
could be  adversely  affected  by  the  failure  or  inability  to  obtain  such
approvals,  by changes in the standards  applicable to approvals and by possible
delays and expenses associated with  obtaining approvals. The failure to  obtain
or  renew any  required regulatory  approvals, licenses  or certifications could
prevent Horizon or CMS from being reimbursed for or offering its services or, in
the case of Horizon, could adversely affect its ability to expand.

    HEALTH CARE REFORM.  Various federal legislators have introduced health care
reform proposals that are intended to  control health care costs and to  improve
access  to medical services for uninsured individuals and to balance the federal
budget by the year 2002. Certain  of these budgetary proposals have been  passed
by  both Houses of Congress and are now in conference committee. These proposals
include reduced  rates of  growth  in the  Medicare  and Medicaid  programs  and
proposals to block grant funds to the states to administer the Medicaid program.
While  these proposals do not, at this time, appear to affect adversely Horizon,
CMS or  the combined  enterprise, significant  changes in  reimbursement  levels
under  Medicare or Medicaid  and changes in  applicable governmental regulations

                                       22
<PAGE>
could significantly affect the future results  of operations of Horizon, CMS  or
the  combined enterprise.  There can  be no  assurance that  future legislation,
health  care  or  budgetary,   or  other  changes   in  the  administration   or
interpretation  of governmental  health care programs  will not  have an adverse
effect on the results of operations of Horizon, CMS or the combined enterprise.

    POTENTIAL LIABILITY;  INSURANCE.    Health care  companies  are  subject  to
medical  malpractice,  personal  injury  and  other  liability  claims  that are
customary risks in  the operation of  health care facilities  and are  generally
covered  by insurance.  Both Horizon  and CMS  maintain property,  liability and
professional malpractice  insurance  in  amounts and  with  such  coverages  and
deductibles  that  are deemed  appropriate  by management,  based  on historical
claims, industry standards and the nature of their respective businesses.  There
can  be no  assurance that  a future claim  will not  exceed available insurance
coverages or that  such policies  will continue to  be available  with the  same
scope  of coverages at reasonable premiums. Any substantial increase in the cost
of such insurance  or the  unavailability of any  such coverages  could have  an
adverse  effect on  business and  results of operations  of Horizon,  CMS or the
combined enterprise.

    DEMAND FOR  PERSONNEL.   The  success and  growth  strategy of  Horizon  are
dependent  in part  on its ability  to attract and  retain competent individuals
with training and experience in  marketing, nursing, therapy and other  clinical
or operating disciplines. The success of CMS is dependent in part on its ability
to  attract and  retain competent  individuals with  training and  experience in
marketing, therapy  and certain  other  disciplines. Such  persons are  in  high
demand and often are subject to competing offers. In past years, the health care
industry  has experienced nursing and therapy  personnel shortages. There can be
no assurance  that Horizon,  CMS or  the  combined enterprise  will be  able  to
attract  and retain the qualified clinical  or operating personnel necessary for
its business and planned growth. A future lack of such personnel could adversely
affect results of operations of Horizon, CMS or the combined enterprise.

    DEPENDENCY ON KEY PERSONNEL.   Horizon is dependent  on a limited number  of
key  officers, the  loss of services  of any one  of whom could  have an adverse
effect on it. Horizon  maintains no key man  life insurance policies.  Horizon's
future  success will depend in part on  its ability to attract and retain highly
qualified individuals to  fill key  management positions.  Horizon competes  for
such  individuals  with  similar  health  care companies  and  there  can  be no
assurance that it will be successful in hiring or retaining qualified personnel.
The loss  of  key  personnel  or  the inability  to  hire  or  retain  qualified
management personnel could adversely affect Horizon's results of operations.

   
    ANTI-TAKEOVER  PROVISIONS.  Horizon's stockholder rights plan, together with
certain provisions in its Certificate of  Incorporation and Bylaws, may make  it
more difficult to effect a change in control of Horizon and to replace incumbent
management.   Such   provisions  could   potentially  deprive   stockholders  of
opportunities to sell shares at above market prices.
    

                                 THE COMPANIES

HORIZON

    Horizon is a leading  provider of long-term care  and specialty health  care
services in selected geographic markets in the United States, principally in the
Midwest,  Southwest and  Northeast. Horizon's long-term  care facilities provide
skilled nursing care and basic patient services with respect to daily living and
general medical  needs. Horizon's  specialty hospitals  and subacute  facilities
provide  a range of high acuity, complex medical services. Horizon also provides
specialty health  care services  to  third parties  and  to its  long-term  care
facilities.  Of total operating revenues,  long-term care services accounted for
71% and 60% and specialty health care services accounted for 27% and 38% for the
years ended May  31, 1993  and May  31, 1994,  respectively. At  April 1,  1995,
Horizon  owned, leased or  managed 133 long-term care  facilities. At that date,
Horizon operated 16  licensed specialty  hospitals and centers  and 15  subacute
care  units,  all  of which,  except  two stand-alone  specialty  hospitals, are
located in discrete  areas of the  physical structures of  certain of  Horizon's
long-term  care facilities. These facilities contain an aggregate of 17,760 beds
located in 18 states.

                                       23
<PAGE>
    Horizon's broad  range of  specialty health  care services  consists of  (i)
subacute  care,  which includes  dedicated programs  for ventilator  care, wound
management, general rehabilitation,  head trauma/coma  stimulation and  infusion
therapy,  (ii) contract rehabilitation therapies,  such as occupational, speech,
physical  and  respiratory  therapies,  (iii)  institutional  pharmacy  services
designed  to  provide  full  pharmaceutical services  and  supplies  to patients
residing in  institutional settings,  (iv)  Alzheimer's care,  (v)  non-invasive
medical diagnostic testing services, such as echocardiography, peripheral venous
and  arterial imaging, holter monitoring,  doppler scanning and sleep diagnostic
services, (vi) home respiratory care services and supplies and home infusion and
intravenous therapies and (vii) clinical  laboratory services that provide  body
fluid  testing to assist in detecting, diagnosing and monitoring diseases in the
subacute and long-term care settings.

    LONG-TERM CARE.  Horizon's long-term care facilities provide skilled nursing
care and routine basic patient services with respect to daily living  activities
and  general medical  needs. Such basic  patient services  include daily dietary
services, recreational  activities, social  services, housekeeping  and  laundry
services,  pharmaceutical  and  medical  supplies and  24  hour-a-day  access to
registered nurses, licensed practical nurses and related services prescribed  by
the  patient's physician. At  April 1, 1995, the  Company operated 133 long-term
care facilities in 18 states.

    SUBACUTE CARE.  Horizon provides subacute care to high acuity patients  with
medically complex conditions who require ongoing, multi-disciplinary nursing and
medical supervision and access to specialized equipment and services, but do not
require  many of the other services provided by an acute care hospital. Subacute
services are  provided under  both hospital  licenses (specialty  hospital)  and
skilled  nursing facility  licenses. Subacute  care services  are provided  in a
discrete area within  the physical  structure of  a specialty  hospital and  are
supervised  by a  separate medical  staff employed  by Horizon.  Such units also
provide ventilator care, intravenous therapy and various forms of coma, pain and
wound management. Horizon  believes that private  insurance companies and  other
third  party payors, including  certain state Medicaid  programs, recognize that
treating patients requiring subacute care in  subacute care units such as  those
operated  by Horizon is a cost effective  alternative to treatment in acute care
hospitals. In addition,  Horizon has 14  facilities which provide  comprehensive
in-patient  rehabilitation  and  skilled and  intermediate  nursing  services to
patients who  have  sustained  traumatic head  injuries  or  other  neurological
impairments.

    CONTRACT  REHABILITATION THERAPIES.  Horizon  provides a comprehensive range
of rehabilitation therapies, including  physical, occupational, respiratory  and
speech  therapies  through  contracts with  third  parties  and in  most  of its
long-term care facilities. As of  April 1, 1995, Horizon provided  comprehensive
physical,  occupational and speech therapy services  through 442 contracts in 21
states serving approximately 40,300 beds, of which approximately 14,200 beds are
in Horizon-operated  long-term  care  facilities  and  specialty  hospitals  and
approximately  26,100 are in third party  long-term care facilities, home health
agencies, hospitals, outpatient clinics and school systems.

    INSTITUTIONAL PHARMACY SERVICES.   Horizon has established  a network of  19
regionally  located  pharmacies  through  which  it  provides  a  full  range of
prescription drugs and  infusion therapy services,  such as antibiotic  therapy,
pain management and chemotherapy, to facilities operated by Horizon and by third
parties.  These  pharmacy  operations (certain  of  which are  managed  by third
parties) enable Horizon to generate  revenues from services previously  provided
to Horizon by third-party pharmacy vendors.

    ALZHEIMER'S  LIVING  CENTERS.    Horizon offers  a  specialized  program for
persons with  Alzheimer's disease  through its  Alzheimer's Living  Centers.  At
April 1, 1995, this program had been instituted at 28 of the Company's long-term
care  facilities with a total of 851 beds. Each Alzheimer's Living Center, which
is located in a  designated wing of  a long-term care  facility, is designed  to
address  the problems of disorientation  experienced by Alzheimer's patients and
to help reduce stress  and agitation resulting from  a short attention span  and
hyperactivity.   Each   Alzheimer's   Living   Center   employs   a   specially-

                                       24
<PAGE>
trained nursing staff and an activities director and engages a medical  director
with  expertise  in  the  treatment of  Alzheimer's  disease.  The  program also
provides education and support to the patient's family.

    NON-INVASIVE  MEDICAL  DIAGNOSTICS.    During  fiscal  1994,  Horizon  began
providing  non-invasive,  portable and  static  diagnostic testing  services for
physicians and acute care hospitals. These services include cardiovascular (both
cardiac imaging and vascular imaging), pelvic and abdominal testing services and
sleep  diagnostic  services.  Horizon  has  recently  expanded  its   diagnostic
expertise  and its diagnostic market through  acquisitions. As a consequence, it
now provides these diagnostic services in 11 states.

    HOME RESPIRATORY CARE.   Commencing  in the  first quarter  of fiscal  1995,
Horizon began providing home respiratory care services and supplies to home care
patients in Texas, Oklahoma, Arkansas, Louisiana, Tennessee and Kentucky through
a  physician  referral  base.  These  supplies  include  gas  and  liquid oxygen
cylinders, oxygen concentrators and  aerosol nebulizers. These services  include
the  provision of  home respiratory supplies  and home  infusion and intravenous
therapies.

    CLINICAL LABORATORY.   Horizon owns  and operates  a comprehensive  clinical
laboratory  to  serve  the  long-term  care  industry.  At  April  1,  1995, the
laboratory provided services to  approximately 9,300 beds  in 73 facilities  and
anticipates  serving a  total of  approximately 12,000  beds by  the end  of the
fourth quarter of fiscal 1995.

Enterprises' equity  interest in  its Texas  pharmacy joint  venture. Under  the
terms  of  the  agreements  between  the  parties,  Horizon  paid  Texas  Health
Enterprises, Inc.  the  sum of  approximately  $24  million in  cash  for  these
operational and related assets.

                                       25
<PAGE>
    DOCTORS  HEALTH  CARE CENTER.   On  March 1,  1995, Horizon  consummated the
acquisition of the Doctors Health Care Center, a 325-bed long-term care facility
located in Dallas,  Texas. Under  the terms  of the  transaction documents,  the
Company  issued approximately 507,813 shares of  Horizon Common Stock (valued at
closing at approximately $13 million) for this facility.

    TOTAL REHABILITATION,  INC.   On  March 20,  1995, Horizon  consummated  the

each in Texas, Colorado and Nevada) consisting of 881 beds, a medical diagnostic
services company,  a  medical diagnostic  laboratory  and two  sleep  diagnostic
companies.  Horizon also undertook  the management of  1,020 long-term care beds
and entered into a  joint venture with another  health care provider to  provide
pharmaceutical  services  and  supplies in  three  states in  the  Northeast. In
connection with these acquisitions, Horizon  paid $11.2 million in cash,  issued
73,214  shares of Horizon Common Stock, guaranteed approximately $6.7 million of
lease and note obligations  and became obligated  to provide approximately  $2.8
million of working capital with respect to certain of the managed facilities.

MERGER SUB

    Merger Sub is a wholly owned subsidiary of Horizon incorporated on March 30,
1995 for the purpose of consummating the Merger.

CMS

    CMS  is  one  of  the  largest  providers  of  comprehensive  inpatient  and
outpatient medical rehabilitation programs and services in the country. CMS  has
a  significant presence in each of the rehabilitation industry's three principal
sectors --  inpatient rehabilitation  care, outpatient  rehabilitation care  and
contract  therapy.  CMS  has  developed and  provides  inpatient  and outpatient
rehabilitation programs  and services  for patients  suffering from  stroke  and
other  neurological and  cardiac disorders, orthopedic  problems, head injuries,
spinal cord  injuries,  work-related  disabilities and  multiple  trauma.  CMS's
inpatient  and outpatient rehabilitation programs  and services are delivered to
patients through a plan of treatment developed by an interdisciplinary team that
includes physician  specialists,  therapists  and  other  medical  personnel  as
determined by the individual patient's needs.

    CMS  currently operates 37 freestanding comprehensive medical rehabilitation
hospitals with a total, as of March 31, 1995, of 2,437 licensed beds located  in
15  states. Many  of CMS's rehabilitation  hospitals are  operated through joint
ventures  with  local  general  acute  care  hospitals,  physicians  and   other
investors.  CMS's rehabilitation  unit management  group operates  inpatient and
outpatient rehabilitation  programs within  acute care  hospitals and  currently
manages 13 rehabilitation units with more than 250 beds.

    CMS's  comprehensive freestanding medical rehabilitation hospitals typically
provide on-site outpatient  services. As of  March 31, 1995,  CMS also  provided
outpatient  services through 136 outpatient rehabilitation clinics, 102 of which
are  operated  as  satellite   facilities  to  CMS's  inpatient   rehabilitation
hospitals.  The  remaining  34  outpatient clinics  are  operated  through CMS's
contract therapy subsidiaries.

    Through  its   contract  therapy   subsidiaries,  CMS   provides   physical,
occupational,  speech and  respiratory therapy services  on a  contract basis to
over 2,300 skilled  nursing facilities, general  acute care hospitals,  schools,
home  health agencies, inpatient rehabilitation hospitals and outpatient clinics
in 32 states.

                                       26

bearing  a later date,  (ii) filing written  notice of such  revocation with the
Secretary of Horizon or CMS, as  appropriate, stating that the proxy is  revoked
or (iii) attending the appropriate Special Meeting and voting in person.

VOTE REQUIRED

    HORIZON.   Horizon's Bylaws provide that the presence at the Horizon Special
Meeting, in person or by proxy, of the holders of a majority of the  outstanding
shares of Horizon Common Stock entitled to vote thereat will constitute a quorum
for  the  transaction  of  business.  On the  Horizon  Record  Date,  there were
29,469,296 shares of Horizon  Common Stock outstanding and  entitled to vote  at
the  Horizon Special  Meeting. The issuance  of Horizon Common  Stock by Horizon
pursuant to the Merger Agreement, does not, under the DGCL, require  stockholder
approval.  The  rules  of  the  NYSE require,  however,  that  such  issuance be
submitted to the stockholders of  Horizon and be approved  by a majority of  the
votes  cast on the proposal,  provided that the total  vote cast on the proposal
represents over  50% of  the  shares of  Horizon  Common Stock  outstanding  and
entitled to vote on the proposal. Abstentions, but not broker non-votes, will be
included  in the total vote and, assuming that holders of over 50% of the shares
of Horizon Common Stock entitled to vote on the proposal cast votes in favor  of
or  against the proposal or  abstain, broker non-votes will  have no effect upon
the outcome of the vote. Abstentions will have the same effect as votes  against
the proposal.

    Under  the applicable provisions of the  DGCL, the Horizon Charter Amendment
will require the affirmative  vote of a majority  of the issued and  outstanding
Horizon  Common  Stock entitled  to vote  thereon  for approval.  In determining
whether the  Horizon Charter  Amendment  has received  the requisite  number  of
affirmative votes, abstentions and broker non-votes will have the same effect as
a vote against the Horizon Charter Amendment.

    CMS.  The presence at the CMS Special Meeting, in person or by proxy, of the
holders  of a majority of the outstanding shares of CMS Common Stock entitled to
vote thereat  will constitute  a quorum  for the  transaction of  business,  and
approval  and adoption of the Merger Agreement require the affirmative vote of a
majority of  the  issued and  outstanding  CMS  Common Stock  entitled  to  vote
thereon.  On the  CMS Record  Date, there were  38,632,286 shares  of CMS Common
Stock  outstanding  and  entitled  to  vote  at  the  CMS  Special  Meeting.  In
determining  whether the Merger  Agreement has received  the requisite number of
affirmative votes, abstentions and broker non-votes will have the same effect as
a vote against the Merger Agreement.

    Rocco A. Ortenzio, Chairman  and Chief Executive Officer  of CMS, Robert  A.
Ortenzio,  President of  CMS, and certain  corporations controlled  by them have
agreed pursuant to the Voting Agreement to  vote all shares of CMS Common  Stock
owned  by them  in favor  of the Merger  Agreement. As  of the  CMS Record Date,
approximately 8.9% of the outstanding shares of CMS Common Stock were subject to
the Voting Agreement. The signatories to  the Voting Agreement have also  agreed
to  vote such shares  against any business combination  proposal or other matter
that may interfere or  be inconsistent with the  Merger or the Merger  Agreement
(including, without limitation, a Competing Transaction). The obligations of the
signatories  to the Voting Agreement are not subject to the continued support of
the Board  of Directors  of CMS  in recommending  approval and  adoption of  the
Merger   Agreement  (although  the  Voting  Agreement  would  terminate  upon  a
termination of the Merger Agreement). See "Voting Agreement."

SOLICITATION OF PROXIES

    In addition to solicitation by mail, the directors, officers, employees  and
agents  of each  of Horizon  and CMS may  solicit proxies  from their respective
stockholders by personal  interview, telephone, telegram  or otherwise.  Horizon
and  CMS will  each bear  the costs  of the  solicitation of  proxies from their
respective stockholders, except that Horizon and  CMS will each pay one-half  of
the  cost of printing  this Joint Proxy  Statement/Prospectus. Arrangements will
also be made with brokerage firms and other custodians, nominees and fiduciaries
who hold of record  voting securities of  Horizon or CMS  for the forwarding  of
solicitation  materials to the  beneficial owners thereof.  Horizon and CMS will
reimburse such brokers, custodians, nominees and fiduciaries for the  reasonable
out-of-pocket expenses incurred by them in connection therewith. CMS has engaged
the  services  of Corporate  Investor Communications,  Inc. to  distribute proxy
solicitation materials to brokers, banks and other nominees and to assist in the
solicitation of  proxies  from  CMS  stockholders  for  a  fee  of  $5,000  plus
reasonable out-of-pocket expenses. Horizon has engaged the services of Georgeson
&  Company Inc. to distribute proxy solicitation materials to brokers, banks and
other nominees  and  to assist  in  the  solicitation of  proxies  from  Horizon
stockholders for a fee of $12,000, plus reasonable out-of-pocket expenses.

OTHER MATTERS

    At  the  date  of  this  Joint  Proxy  Statement/Prospectus,  the  Boards of
Directors of Horizon  and CMS do  not know of  any business to  be presented  at
their  respective  Special  Meetings other  than  as  set forth  in  the notices
accompanying this Joint Proxy Statement/Prospectus. If any other matters  should
properly  come before the  respective Special Meetings, it  is intended that the
shares represented by  proxies will  be voted with  respect to  such matters  in
accordance with the judgment of the persons voting such proxies.

                                   THE MERGER

GENERAL DESCRIPTION OF THE MERGER

    The  Merger Agreement provides that, at  the Effective Time, Merger Sub will
merge with and into  CMS with CMS becoming  the Surviving Corporation, and  each
outstanding  share of CMS  Common Stock (other  than shares of  CMS Common Stock
held in the treasury  of CMS or owned  by Horizon or by  any direct or  indirect
wholly  owned subsidiary of Horizon  or of CMS, all  of which will be canceled),
will be  converted into  .5397 shares  of Horizon  Common Stock.  Any  resulting
fractional  shares will be settled in cash.  As a consequence of the Merger, CMS
will become a wholly owned subsidiary of Horizon.

    Based on the number of shares of CMS Common Stock outstanding as of the  CMS
Record Date, 20,849,844 shares of Horizon Common Stock will be issuable pursuant
to  the Merger Agreement  (assuming no issuance  prior to the  Effective Date of
shares of CMS Common Stock  upon exercise of CMS  Options or CMS Warrants,  upon
conversion  of the  CMS Debentures  or pursuant  to the  CMS Earnout Agreements)
representing  approximately  41%  of  the  total  Horizon  Common  Stock  to  be
outstanding after such issuance (based on the number of shares of Horizon Common
Stock outstanding as of the Horizon Record Date).

BACKGROUND

    The   terms  of  the  Merger  Agreement   are  the  result  of  arm's-length
negotiations between  representatives of  CMS and  Horizon. The  following is  a
brief   discussion  of  the   background  of  these   negotiations  and  related
transactions.

    During  late  1994,  in  response   to  Horizon's  increased  equity   base,
representatives  of a commercial  bank and several  investment banking firms met
with the  Chief  Executive Officer,  Neal  M.  Elliott, and  other  officers  of
Horizon,  and  identified  certain  companies  that  they  considered  might  be
interested in a sale of certain assets. The Hillhaven Corporation ("Hillhaven"),
a company engaged in substantially

                                       29
<PAGE>
the same business  as Horizon,  and CMS's contract  therapy services  operations
were  cited by  these organizations. Horizon  had previously  been exploring the
possibility of making a proposal for a combination with Hillhaven.

    Mr. Elliott,  who had  been acquainted  with Rocco  A. Ortenzio,  the  Chief
Executive  Officer of  CMS, for  a number  of years,  contacted Mr.  Ortenzio in
December 1994 by telephone to determine whether Mr. Ortenzio would be interested
in discussing the possibility  of a joint  venture with Horizon  in the area  of
contract  therapy services operations.  Mr. Ortenzio expressed  a willingness to
listen to Mr. Elliott's views.

    On January 26, 1995, Horizon announced publicly that it had made a  proposal
to Hillhaven for a business combination involving the issuance of Horizon Common
Stock to the stockholders of Hillhaven.

    On  February 3,  1995, the  two chief  executive officers  and certain other
officers met at  the offices  of CMS  to discuss  the potential  for a  contract
therapy  services  joint venture  between the  two  companies. This  meeting was
introductory and exploratory in nature and did not deal with the details of  any
particular form or terms of a transaction.

    On  February 6, 1995, Hillhaven publicly rejected Horizon's initial proposal
for a business  combination without  entering into  discussions or  negotiations
with Horizon.

    On February 9 and 10, the Chief Financial Officer of CMS and the Senior Vice
President  of Subsidiary Operations of Horizon  met at Horizon's headquarters to
continue  the  discussions  related  to   the  proposed  joint  venture.   These
discussions  were preliminary  and exploratory  and were  focused on  each party
acquiring an  understanding of  the contract  therapy services  business of  the
other,  but not on  the terms of  any particular transaction.  At that time, the
parties executed a  confidentiality agreement prior  to exchanging  confidential
information  with each  other in  connection with  their investigations  of each
other's contract therapy services business. The parties also consulted technical
advisors concerning tax, reimbursement,  accounting and other structural  issues
relating to a possible joint venture.

    On  February  20, 1995,  a dinner  meeting was  held at  a hotel  in Boston,
Massachusetts. In  attendance  at that  meeting  were the  two  chief  executive
officers,  the Executive Vice President of Horizon, the Senior Vice President of
Subsidiary Operations of  Horizon, and the  Chief Financial Officer  of CMS.  At
this  meeting, the parties  worked on structuring  the proposed contract therapy
services joint venture and reviewed its economic potential. As a result of  that
meeting,  Horizon's  Senior  Vice  President of  Subsidiary  Operations  went to
Mechanicsburg on February 21, 1995, with CMS's Chief Financial Officer to gather
more information regarding the contract  therapy services operations of CMS.  At
that  time, CMS's Chief Financial Officer and Horizon's Senior Vice President of
Subsidiary  Operations  initialed  an  amendment   to  the  February  9,   1995,
confidentiality  agreement  to  expand its  coverage  to  potential transactions
beyond the contract  therapy services joint  venture, and information  regarding
CMS's operations was provided.

    Preparatory  to  meetings during  the following  days, both  chief executive
officers and other  officers of Horizon  and CMS met  for dinner at  a hotel  in
Mechanicsburg  on February  26, 1995.  On February  27 and  28, 1995,  the chief
executive  officers  and  other  officers   of  both  companies  met  in   CMS's
Mechanicsburg  office to discuss further the feasibility of the contract therapy
joint venture  and to  discuss  a broader  business  combination. A  variety  of
personnel   were  assigned  responsibilities  to   review  and  visit  operating
facilities of the respective companies. These visits occurred during the  period
from February 28, 1995 through March 1, 1995.

    On  March 6 and 7, 1995, there were meetings between officers of Horizon and
CMS for the purpose of acquiring further information regarding the businesses of
the two companies.  All these discussions  were exploratory regarding  primarily
the  formation of a joint venture in  the contract therapy services business or,
secondarily, a possible business combination.

                                       30
<PAGE>
    On March 7, 1995,  Horizon publicly announced an  increase in the amount  of
Common  Stock that it would  be willing to issue  in a business combination with
Hillhaven and that the offer would expire on March 21, 1995. Specifically, total
consideration was increased from approximately $1.3 billion to $1.7 billion.

    On March 8, 1995, at a regular meeting of the Board of Directors of CMS, the
Board reviewed CMS's  continuing discussions  with Horizon with  respect to  the
potential joint venture in the contract therapy services business. At that time,
management of CMS also reported to the Board that the analysis and due diligence
discussions  had been extended to include a  possible merger of CMS and Horizon.
The CMS Board discussed the potential strategic benefits to CMS of a combination
with a company in the long-term health care field and of the specific advantages
of a combination with Horizon.

    On March  13, 1995,  the Board  of Directors  of Horizon,  at its  regularly
scheduled  meeting, discussed management's request for authority to enter into a
contract therapy services joint  venture with CMS.  Included in that  discussion
was the possibility of some other form of business combination and the directors
were  furnished with  detailed financial  information with  respect to  both the
proposed joint venture and a possible business combination. After exploring  the
subject  in detail, the Board of  Directors authorized management to negotiate a
joint venture arrangement. Promptly thereafter, management of Horizon  presented
a draft letter of intent to CMS regarding the formation of a joint venture.

    The  objective of management of Horizon in pursuing a joint venture with CMS
in the contract  therapy services  business had  been to  enhance the  potential
synergies  of a transaction with Hillhaven.  As the negotiations progressed, the
parties determined  that the  joint  venture, in  the form  contemplated,  could
potentially  prevent  one  or  both  parties  from  subsequently  engaging  in a
transaction accounted for as a  pooling of interests, a  matter deemed to be  of
importance  to both  companies, especially to  Horizon in light  of its proposed
transaction with Hillhaven.

    On March 21, 1995,  Horizon's proposal to  Hillhaven expired without  having
been accepted by Hillhaven and was not renewed.

    On  March  22, 1995,  Mr. Elliott  contacted Mr.  Ortenzio by  telephone and
suggested that,  in lieu  of  a joint  venture  transaction, the  parties  begin
serious  negotiations concerning a merger of the two companies. Mr. Ortenzio was
amenable to this proposal. At that time, Merrill Lynch, CMS's financial advisor,
began to work on the preparation of its valuation analyses.

    On March 23,  1995, at  a special  meeting of  the CMS  Board of  Directors,
senior  management of CMS  explained in detail  Horizon's proposal and discussed
Horizon, its business and financial  condition and operating results. The  Board
discussed the Horizon proposal and reviewed the significant strategic advantages
and  synergies identified in  connection with the proposed  joint venture of the
two companies' contract therapy services  business and considered the  strategic
benefits  of  also  combining  CMS's  rehabilitation  hospitals  and out-patient
services  with  Horizon's  long-term  and  subacute  care  facilities.  At   the
conclusion  of  this  meeting,  the CMS  Board  of  Directors  authorized senior
management to continue with negotiating the merger transaction.

    On March 24, 1995, Horizon engaged Salomon Brothers to render an opinion  to
the  Board  of Directors  of  Horizon with  respect to  the  fairness of  such a
business combination, from  a financial point  of view, to  the stockholders  of
Horizon.

    On  March 27, 1995, the chief executive officers, together with other senior
officers of both companies  and their outside advisors,  met in Albuquerque  and
reached  a  mutual understanding  with  respect to  the  basic framework  of the
proposed  transaction.   From  March   27,  1995,   through  March   31,   1995,
representatives,   including  their  financial  advisors,  of  Horizon  and  CMS
conducted further investigations of  each other. Commencing  on March 29,  1995,
representatives of Horizon and CMS, including their financial advisors and legal
counsel, met to discuss and resolve business and legal

                                       31
<PAGE>
issues  related  to  the  proposed  combination.  During  the  course  of  these
discussions, the  representatives  of  the  parties  negotiated  the  terms  and
provisions  of the Merger  Agreement, the Voting Agreement  and the Stock Option
Agreement.

    On March  29, 1995,  CMS's Board  of Directors  met and,  together with  its
outside  advisors, considered in  detail the proposed  business combination with
Horizon. CMS's Board of  Directors reviewed the material  terms of the  business
combination that representatives of Horizon and CMS had discussed to that point,
including  the  material  terms  of the  draft  Merger  Agreement,  Stock Option
Agreement and  Voting Agreement,  and the  Board requested  CMS's management  to
negotiate  further  certain of  such terms  with Horizon.  Merrill Lynch  made a
presentation to  the  Board  analyzing the  proposed  transaction,  including  a
valuation  of CMS  using various methodologies.  See " --  Opinions of Financial
Advisors --  CMS."  CMS's  legal  counsel  made  a  presentation  to  the  Board
concerning  the Board's fiduciary duties to  CMS's stockholders in considering a
business combination.

    On March 31,  1995, the CMS  Board of  Directors met again  and resumed  its
discussion  of the proposed merger. At this time, Merrill Lynch reviewed certain
aspects of its  valuation presentation with  the Board of  Directors of CMS  and
delivered its oral opinion, which was subsequently confirmed in writing, that as
of  such date and based  on the assumptions made  and matters considered in, and
the limitations  on, the  review  undertaken by  Merrill  Lynch as  reviewed  by
Merrill  Lynch with the Board of Directors  of CMS, the Exchange Ratio was fair,
from a financial point  of view, to  the CMS stockholders.  See "-- Opinions  of
Financial  Advisors -- CMS." After consideration of the opinion of Merrill Lynch
and additional  consideration of  the topics  presented at  the March  29,  1995
meeting,  the directors present  at the meeting  unanimously approved the Merger
Agreement and  the related  transactions. The  CMS Board  also amended  the  CMS
Rights  Agreement, dated March 11,  1991, between CMS and  Mellon Bank, N.A., as
rights agent, as amended to date  (the "CMS Rights Agreement"), to provide  that
neither  the  Merger nor  any  of the  transactions  contemplated by  the Merger
Agreement, the Voting Agreement or the Stock Option Agreement would be an  event
that  triggers the distribution or exercisability of rights under the CMS Rights
Agreement.

    On March 31,  1995, Horizon's Board  of Directors met.  After reviewing  the
results  of Horizon's due diligence with  respect to CMS, reviewing the material
terms of the Merger Agreement, the Voting Agreement, the Stock Option  Agreement
and  other transaction  documents and  receiving Salomon  Brothers' oral opinion
(which was later confirmed in writing) that, as of such date, the  consideration
to  be paid by Horizon  in the Merger was fair  to Horizon's stockholders from a
financial point of view, Horizon's  Board authorized the execution and  delivery
of  the Merger Agreement,  the Voting Agreement, the  Stock Option Agreement and
other  transaction  documents.  After  the   meeting,  an  officer  of   Horizon
communicated the results of the meeting to an officer of CMS.

    On  the  afternoon  of March  31,  1995,  the Merger  Agreement,  the Voting
Agreement, the  Stock  Option Agreement  and  other transaction  documents  were
executed  and  delivered,  and Horizon  and  CMS  issued a  joint  press release
announcing the execution of the definitive agreements.

CERTAIN INFORMATION PROVIDED

    In connection with the discussions between Horizon and CMS described  above,
Horizon  provided to CMS certain  preliminary financial projections with respect
to  Horizon's   operating  results,   cash  flows   and  financing   activities,
capitalization  and capital expenditures for fiscal years 1995 and 1996, and the
assumptions on  which  such  financial  forecasts  were  based.  Such  financial
forecasts  were  developed for  internal use  only, were  not prepared  with the
intent  that  they  would  be  publicly  distributed,  were  based  on  numerous
assumptions  (many  of which  are beyond  the  control of  Horizon) and  are not
necessarily indicative of future results. Such preliminary financial projections
assumed a  consolidated compound  average  annual revenue  growth of  19.5%  and
average EBITDAR (earnings before interest, taxes, depreciation, amortization and
rent  expenses  for  hospitals and  similar  facilities) margins  of  20.7% (the
"Horizon Base Case"). Such projections do  not include any special charges  that
relate to the operations of any entity acquired by Horizon for any periods prior
to acquisition.

                                       32
<PAGE>
    In  connection with the discussions between Horizon and CMS described above,
CMS provided to  Horizon certain preliminary  financial projections relating  to
CMS's  fiscal years 1995 and 1996 and  the assumptions on which such projections
were based.  Such preliminary  financial projections  were prepared  by CMS  for
internal use only, were not prepared with the intent that they would be publicly
distributed,  were based on  numerous assumptions (many of  which are beyond the
control of CMS)  and are  not necessarily  indicative of  future results.  These
financial projections were prepared by management of CMS based on the assumption
of  a consolidated  compound average annual  revenue growth of  7.3% and average
EBITDA (earnings before interest, taxes, depreciation and amortization)  margins
of  12.5% (the "CMS Base Case"). The  CMS projections were adjusted to eliminate
any special charge reflected in the unaudited consolidated financial  statements
of  CMS (which,  for the  nine months  ended March  31, 1995,  reflected special
charges of $18.4 million). (See "CMS Selected Historical Consolidated  Financial
Information.")  The  projections  included  the  anticipated  expense reductions
resulting from the special charges reported by CMS during fiscal 1994 and fiscal
1995, including the special  charge recorded for the  third quarter ended  March
31, 1995.

    Horizon  provided EBITDAR information and CMS provided EBITDA information as
additional financial  data  to  measure  their  respective  projected  operating
performance. Although such data is commonly used by the investment community, it
may  not be representative of, and is not a substitute for, operating results or
net income  for  the  periods  presented  under  generally  accepted  accounting
principles. For example, the companies do not consider EBITDAR or EBITDA data to
be representative measures of their respective operating cash flows.

    Once  each party had received each  other's financial forecasts as indicated
above, the parties, with  the assistance of  their financial advisors,  extended
such  forecasts  through  the fiscal  year  2000. The  extended  forecasts were,
however, largely mathematical derivations from the initial forecasts.

HORIZON'S REASONS FOR THE MERGER; RECOMMENDATION OF HORIZON BOARD OF DIRECTORS

    CMS is engaged in the businesses of operating 37 rehabilitation hospitals in
15 states,  providing  outpatient  rehabilitation  services  at  more  than  130
locations,  managing 13  inpatient rehabilitation  units and  providing contract
therapy services  in  more  than  30  states  to  more  than  2,300  facilities.
Management  of Horizon believes that the Merger  of CMS with Horizon will create
one of the  nation's major post-acute  care companies and  will be the  nation's
largest  specialty  health  care  provider. The  combined  company  will  have a
substantial capability  in a  large  array of  post-acute care  services:  acute
medical  rehabilitation;  outpatient  rehabilitation;  subacute  care; long-term
care; contract  therapy; institutional  pharmacy services;  clinical  laboratory
services;  medical  diagnostic  services;  and  home  care  services.  Moreover,
management of Horizon believes that  the combined company will have  significant
growth opportunities, particularly in acquisitions of additional long-term care,
subacute  care and outpatient facilities,  internal development of specialty and
rehabilitation hospitals, the  expansion of  contract therapy  services and  the
addition of other specialty services.

    The  analyses of the combined company performed by management of Horizon and
Salomon Brothers indicate that  there are significant  synergies to be  realized
through  the combination, particularly through  (i) revenue enhancement and cost
savings  from  consolidation  of   contract  therapy  operations;  (ii)   margin
improvements  from  enhanced  utilization  of  contract  therapists;  (iii)  the
expansion of Horizon's institutional pharmacy  services into CMS facilities  and
new  markets;  (iv)  the  consolidation  of  corporate  overhead;  and  (v)  the
introduction of other specialty services.

    Management of Horizon  also believes that  there are other  synergies to  be
realized  from  a combination  of  the companies  which  are not  susceptible of
quantification. Among them are  (i) the potential  to increase business  through
the  ability to provide  a full range of  care to managed  care payors; (ii) the
ability  to  increase  capacity  and  margins  in  rehabilitation  hospitals  by
transferring  patients to Horizon subacute  and long-term care facilities; (iii)
the potential to increase patient volume  by expanding the continuum of care  of
each    company    on    a    stand   alone    basis;    (iv)    the   potential

                                       33
<PAGE>
to retain therapist employees  by providing an  exceptional career path  ranging
from  acute rehabilitation hospital positions  to skilled nursing contracts; (v)
the potential for  improved buying  power with  respect to  suppliers; and  (vi)
reduced capital costs through the refinancing of CMS indebtedness.

    These  analyses also  indicate that  the valuation  of CMS  under the Merger
Agreement falls within the range suggested by market measures of value. See  "--
Opinions  of  Financial  Advisors."  They further  suggest  that,  based  on the
preliminary financial projections adjusted as discussed under
"-- Certain  Information Provided,"  (i)  CMS should  contribute over  half  the
revenues  and almost half the net income of the combined company for fiscal 1996
and (ii) while it would likely be dilutive to Horizon's net income per share  in
fiscal  1995, the  proposed Merger  should be  neutral to  somewhat accretive to
Horizon's net  income per  share in  fiscal  1996 before  giving effect  to  any
expected  synergies from the transaction. For more detailed information, see "--
Opinion of  Financial  Advisors --  Horizon  -- Pro  Forma  Merger  Consequences
Analysis."

    Horizon's  management  believes  investor apprehension  over  pending salary
equivalency reimbursement limitations for occupational therapists and speech and
language pathologists has created questions as to the value of contract  therapy
companies.  See  "Governmental and  Regulatory  Approvals and  Matters." Horizon
believes this  is an  overreaction to  the ultimate  effect of  these  potential
reimbursement  limitations on future revenues and margins. Horizon also believes
that this  reduced  valuation  of  contract  therapy  companies  creates  unique
acquisition  opportunities. Horizon  further believes  that the  proposed Merger
would result in a  combined enterprise which  would be an  industry leader in  a
managed  health care environment.  For these reasons,  the management of Horizon
deemed it appropriate to seek a business combination with CMS at this time.

    The Board of Directors of Horizon  believes that the Exchange Ratio and  the
other  terms of the Merger Agreement are fair  to, and in the best interests of,
Horizon and the stockholders of  Horizon. In reaching its conclusion,  Horizon's
Board  considered (i) the matters set forth  above, (ii) the judgment and advice
of Horizon's  management,  (iii)  the prior  financial  performance  and  future
operating  prospects of  CMS, (iv)  the reasonableness  of achieving prospective
cost savings and future  incremental revenues from  the combined operation,  (v)
the financial flexibility offered by the combination, (vi) the historical prices
and trading information for Horizon Common Stock and CMS Common Stock, (vii) the
respective  valuations of  each company  based on  several different  methods of
valuation, (viii) detailed financial information, including historical financial
information for  each  company  and  pro  forma  combined  financial  statements
reflecting  effectuation of  the Merger, (ix)  the results of  the due diligence
review of the business  and operations of CMS,  (x) the complementary nature  of
the  expertise of employees and other resources  of each company, (xi) the terms
of the Merger  Agreement, the Voting  Agreement and the  Stock Option  Agreement
(including   the  termination  fee  arrangements  and  the  proposed  employment
arrangements (which were subsequently modified in certain respects) with respect
to the Chairman  and President of  CMS), (xii) the  opinion of Salomon  Brothers
described below and (xiii) the probability of achieving expected results.

    In  analyzing the Merger Agreement, the  Horizon Board of Directors received
an oral opinion from Salomon Brothers at  its March 31, 1995 meeting (which  was
subsequently  confirmed in writing) that, as  of such date, the consideration to
be paid by Horizon in the Merger was fair to the holders of Horizon Common Stock
from a financial  point of  view. At  such meeting,  the Board  of Directors  of
Horizon  entertained a  detailed description of  the procedures  used by Salomon
Brothers in  arriving at,  and the  bases for,  its conclusions  and  thereafter
accepted  the oral  opinion. The  Horizon Board of  Directors did  not adopt the
opinion of Salomon Brothers as the exclusive basis for the Board's determination
as to the  fairness of  the Exchange  Ratio and the  other terms  of the  Merger
Agreement  to Horizon and the stockholders of Horizon; rather, the Horizon Board
of Directors,  as indicated  above, included  the opinion  in the  total mix  of
information  regarding the proposed Merger that  was available to, and evaluated
by, it. (Salomon  Brothers subsequently delivered  the Salomon Brothers  Opinion
dated  the date of this Joint Proxy  Statement/Prospectus that, as of such date,
the consideration to be paid by Horizon in the Merger was fair to the holders of
Horizon Common Stock from a

financial point of view.) See "-- Opinions of Financial Advisors -- Horizon" for
information regarding the assumptions  made and matters  considered in, and  the
limitations  on,  the review  undertaken by  Salomon  Brothers and  on Horizon's
agreement to compensate and indemnify Salomon Brothers.
    

    In evaluating the foregoing factors, the Board of Directors understood  that
the implications of some of the factors were negative rather than positive.

    1995 DILUTION.  The analyses of the combined company performed by management
of  Horizon  and  Salomon  Brothers indicated  that,  based  on  the preliminary
financial projections  adjusted  as  discussed  under  "--  Certain  Information
Provided,"  the proposed Merger would be likely  to be dilutive to Horizon's net
income per  share in  fiscal 1995.  In  fact, the  Salomon Brothers  Report,  as
discussed  under "Opinions of Financial Advisors  -- Horizon -- Pro Forma Merger
Consequences Analysis," indicates that the analysis described therein showed pro
forma dilution to  the stockholders of  Horizon in earnings  per share  (without
giving  effect to any  projected synergies) for the  projected period ending May
31, 1995 ranging (depending on the final exchange ratio) from 10% to 2.3%. Based
on the final Exchange Ratio, the projected dilution would be 10%.

    PRIOR FINANCIAL PERFORMANCE.  In its evaluation of CMS, the Horizon Board of
Directors reviewed the historical financial information relating to CMS and  its
consolidated  subsidiaries. The  Horizon Board  was apprised  of, and  took into
account, the  consolidated results  of operations  of CMS  and its  consolidated
subsidiaries  during  the fiscal  years  1993 and  1994,  in which  CMS recorded
special charges of $14.5 million and $74.8 million, and for the six months ended
December 31, 1994, in which CMS recorded special charges of $13.4 million.

    DUE DILIGENCE.  As  part of its  review, the Board  of Directors of  Horizon
also  considered certain  compliance and  regulatory issues  currently affecting
CMS. During the  course of  Horizon's examination of  CMS, Horizon's  management
reviewed information provided by CMS regarding an employment tax audit currently
being  conducted  by the  Internal  Revenue Service  (the  "IRS Audit")  and the
pending inquiries of the U.S. Department of Justice with respect to certain  CMS
operations  (the "DOJ Inquiry"). Horizon's management and legal counsel attended
a presentation by  CMS and  its tax  and regulatory  counsel on  March 30,  1995
regarding  these matters.  During the course  of that  presentation, the Horizon
representatives were  advised that  (i) the  IRS Audit  was in  its  preliminary
stages  and that no assessment had been  asserted, (ii) the DOJ Inquiry had been
previously reported by CMS (in the Quarterly Report on Form 10-Q for the quarter
ended December 31, 1994) and (iii) these  matters were not expected to have  any
material  adverse effect on the financial  condition or results of operations of
CMS. In reaching its determination with respect to the Merger, the Horizon Board
of Directors  assessed  these matters  on  the  basis of  the  information  made
available  to  Horizon's  representatives and  the  evaluation by  them  of that
information in  the context  of the  proposed Merger  and the  Horizon Board  of
Directors  recognized  that, notwithstanding  the  expectations of  CMS  and its
advisors, there was no  assurance that these matters  would not have a  material
adverse effect on the financial position or results of operations or business of
CMS.

    These  factors  were  regarded  by  the Board  of  Directors  of  Horizon as
negative. All  of  the other  factors  to which  reference  is made  above  were
regarded  by the Board of Directors as  positive. The Board of Directors did not
assign relative weights  to any  of the factors  considered by  it; rather,  the
Board  evaluated  the proposed  Merger  based on  the  total mix  of information
available to it. Based on the totality  of that information, all members of  the
Board  of Directors of  Horizon, at the  special meeting held  on March 31,1995,
expressed support for the Merger and the Board of Directors unanimously approved
the Merger Agreement and the Horizon Charter Amendment and recommended that  the
stockholders of Horizon vote "FOR" approval and adoption of the Merger Agreement
and approval and adoption of the Horizon Charter Amendment.

CMS'S REASONS FOR THE MERGER; RECOMMENDATION OF CMS BOARD OF DIRECTORS

    At  a meeting held on March 31, 1995 the Board of Directors of CMS concluded
that the Merger was  fair to and  in the best interests  of the stockholders  of
CMS,  approved the Merger Agreement and recommended that the stockholders of CMS
approve and adopt the Merger Agreement.

    As part of its  review, the CMS Board  of Directors considered, among  other
things,  information  presented  by  CMS  management,  Merrill  Lynch  and legal
counsel, including information relating to the relative resources and  strengths
of  each company, and their respective business lines, geographic dispersion and
long-term strategic  focus. See  "-- Opinions  of Financial  Advisors." The  CMS
Board of Directors considered information concerning the current and prospective
status  of the  rehabilitation and  long-term care  industries and  the relative
capabilities and strengths of the management  of each company. The CMS Board  of
Directors  also considered the  unique strategic opportunities  the Merger would
provide for CMS  to extend its  clinical expertise and  expand the continuum  of
health  care services it can offer  to include the complementary long-term care,
contract services and  other related  businesses of  Horizon. The  CMS Board  of
Directors  also considered certain other financial information, including (among
other things) historical financial information for each of the companies and pro
forma combined financial information reflecting  the effects of the Merger,  the
results  of the due diligence  review of the business  and operations of Horizon
conducted by CMS's management and advisors,  the ability of the combined  entity
to  raise  additional  debt  and  equity  capital  on  a  favorable  basis,  the
complementary nature of the  employee expertise and other  resources of CMS  and
Horizon   and  the  possibility  of   achieving  specific  savings  by  reducing
duplicative  administrative  costs.  In  addition,  the  Board  considered   the
prospects of CMS on both a stand-alone and combined basis, and the likelihood of
obtaining  by other  means the strategic  advantages offered by  the Merger. The
Board also reviewed  in detail the  terms of the  Merger Agreement, the  related
transactions,  including the  terms of  the Stock  Option Agreement,  the Voting
Agreement and  the proposed  employment arrangements  with the  Chief  Executive
Officer  and the President  of CMS (which were  subsequently modified in certain
respects), and the termination fee  payable to Horizon in certain  circumstances
if the transaction is not consummated.

    In  reaching  its determination,  the CMS  Board  of Directors  considered a
number of factors,  including, without limitation,  the matters discussed  above
and the following:

        (i) the immediate and potential long-term benefits to CMS's stockholders
    inherent  in the  terms of  the Merger and  the long-term  prospects for the
    combined entities;

        (ii) the oral opinion  of Merrill Lynch (which  was accepted by the  CMS
    Board  of Directors and  was subsequently confirmed in  writing) that, as of
    March 31, 1995 and based on the assumptions made and matters considered  in,
    and  the limitations on, the review undertaken by Merrill Lynch as discussed
    by Merrill Lynch  with the  Board of Directors  of CMS,  the exchange  ratio
    contemplated  by the  Merger Agreement was  fair to the  stockholders of CMS
    from a financial point of view;

       (iii) the strategic benefits  of significantly expanding CMS's  continuum
    of  offered health care  services and of taking  advantage of CMS's existing
    expertise in clinical care, rehabilitation services and contract services to
    enhance  CMS's  competitive  position   in  an  increasingly  managed   care
    environment;

       (iv) a conclusion that further consolidations in the health care industry
    were  inevitable, including in contract therapy  services, that CMS could be
    at  a  competitive  disadvantage  as   a  stand-alone  entity  in  such   an
    environment,  and that market conditions were  favorable to a transaction in
    the current time frame;

        (v) the  compatibility  of  the  respective  businesses  and  management
    philosophies  of  CMS  and  Horizon  with  a  common  emphasis  on low-cost,
    efficient health care delivery systems;

       (vi)  the  potential   cost  savings  in   management  and  general   and
    administrative expenses;

                                       36
<PAGE>
       (vii) the opportunity to achieve significant synergies through exploiting
    economies  of scale afforded by  the transaction, including greater leverage
    as a purchaser;

      (viii) the diversification of market risks inherent in the combination  of
    the two entities' businesses;

       (ix)  the relative prospects for growth and growth in shareholder values,
    as a stand-alone entity and as a part of a substantially larger organization
    operating in economically diversified trading areas;

        (x) the  relative  prospects for  raising  capital in  current  industry
    conditions as a stand-alone entity and as part of a larger organization; and

       (xi)  the tax-free nature of the  transaction to CMS stockholders and the
    advantageous effects on the combined enterprise as treating the  transaction
    as a pooling for accounting purposes.

    The  CMS  Board of  Directors  also took  into  consideration the  fact that
Horizon has grown rapidly through a number of relatively recent acquisitions and
that these acquired businesses may not have been fully integrated into Horizon's
existing management, operational and other systems. The Board also evaluated the
risks,  inherent  in  any  transaction  such  as  the  Merger,  that   currently
unanticipated  difficulties  could arise  in integrating  the operations  of two
large  corporations;  and  that  the  synergies  expected  from  combining   the
operations  of CMS and Horizon  may not be realized.  In addition, the CMS Board
reviewed the relatively greater dependence of Horizon on Medicaid-based revenues
and the  possibility  of  significant  changes in  the  Medicaid  program  as  a
consequence  of  deficit  reduction  and health  care  reform  legislation being
considered by the  United States Congress.  The CMS Board  also considered  that
Horizon's  Common Stock price was  trading at a relatively  high multiple to its
earnings, raising the possibility of greater  volatility in its stock price  and
the  risk that  the Horizon  Common Stock to  be received  by CMS's stockholders
would decline  in value  between the  signing of  the Merger  Agreement and  the
closing   of  the  Merger  or  thereafter.  The  CMS  Board  also  reviewed  the
restructuring of its  operations that had  begun in fiscal  1994 and  considered
whether  a  more favorable  transaction  could be  obtained  by waiting  for the
benefits of the restructuring to be further realized, in light of the risks that
these benefits could be delayed and that the significant strategic opportunities
presented by the Merger would be lost if CMS did not pursue the Merger. The  CMS
Board  of Directors  viewed the factors  described in this  paragraph as perhaps
militating against the Merger, but determined that they did not provide a  basis
for  deferring or rejecting the  Merger. The CMS Board  also recognized that the
possibility of a higher offer was not precluded by the Merger Agreement.

   
    In analyzing the proposed Merger, the  CMS Board of Directors evaluated  the
factors  and considerations described above and consulted with its financial and
legal advisors and with CMS management. The CMS Board of Directors did not adopt
the  opinion  of  Merrill  Lynch  as   the  exclusive  basis  for  the   Board's
determination  as to the fairness  of the Exchange Ratio  and the other terms of
the Merger  Agreement to  the stockholders  of  CMS; rather,  the CMS  Board  of
Directors,  as  indicated  above,  included  the opinion  in  the  total  mix of
information regarding the proposed Merger  that was available to, and  evaluated
by,  it. The CMS Board of Directors did not view any one factor as determinative
and did not assign particular weight to any one factor. Based on the information
presented to the  directors, the  members of  the Board  of CMS  present at  the
special meeting held on March 31, 1995 unanimously approved the Merger Agreement
and  recommended that the stockholders of CMS vote FOR the adoption and approval
of the Merger Agreement. Prior to reaching its conclusion as to the fairness  of
the  Merger, the Board of Directors of CMS also considered the matters described
in the first paragraph under "-- Interests of Certain Persons in the Merger."
    

OPINIONS OF FINANCIAL ADVISORS

HORIZON

    Salomon Brothers delivered to the Horizon Board its written opinion that, as
of March 31, 1995, the  consideration to be paid  by Horizon in connection  with
the Merger was fair to the holders of

                                       37
<PAGE>
Horizon Common Stock from a financial point of view. No limitations were imposed
by  the Horizon Board  upon Salomon Brothers with  respect to the investigations
made or the procedures followed by it in rendering its opinion.

    SALOMON BROTHERS SUBSEQUENTLY DELIVERED  THE SALOMON BROTHERS OPINION  DATED
THE  DATE OF THIS  JOINT PROXY STATEMENT/PROSPECTUS  THAT, AS OF  SUCH DATE, THE
CONSIDERATION TO BE PAID BY  HORIZON IN CONNECTION WITH  THE MERGER WAS FAIR  TO
THE  HOLDERS OF HORIZON COMMON STOCK FROM A FINANCIAL POINT OF VIEW. THE SALOMON
BROTHERS OPINION IS  SUBSTANTIALLY SIMILAR  TO THE OPINION  OF SALOMON  BROTHERS
DATED  MARCH 31, 1995. THE FULL TEXT OF THE SALOMON BROTHERS OPINION, WHICH SETS
FORTH ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITS ON THE REVIEW  UNDERTAKEN,
IS  ATTACHED AS  APPENDIX B TO  THIS JOINT PROXY  STATEMENT/ PROSPECTUS. HORIZON
STOCKHOLDERS ARE URGED  TO READ  THE OPINION IN  ITS ENTIRETY.  THE OPINIONS  OF
SALOMON  BROTHERS ARE DIRECTED ONLY  TO THE FAIRNESS OF  THE CONSIDERATION TO BE
PAID  BY  HORIZON  AND  DO  NOT  CONSTITUTE  A  RECOMMENDATION  TO  ANY  HORIZON
STOCKHOLDER  AS TO HOW SUCH STOCKHOLDER SHOULD VOTE. THE SUMMARY OF THE OPINIONS
OF SALOMON  BROTHERS SET  FORTH  IN THIS  JOINT PROXY  STATEMENT/PROSPECTUS  ARE
QUALIFIED  IN  THEIR ENTIRETY  BY  REFERENCE TO  THE  FULL TEXT  OF  THE SALOMON
BROTHERS OPINION.

    In arriving  at  its opinions,  Salomon  Brothers (i)  reviewed  the  Merger
Agreement  and its related  schedules, (ii) reviewed  certain publicly available
business and financial information relating  to Horizon and CMS, (iii)  reviewed
certain  other information, including financial projections, provided to Salomon
Brothers by Horizon and CMS  and (iv) met with  members of senior management  of
both  Horizon and CMS to  discuss the past and  current operations and financial
condition and prospects  of Horizon  and CMS. Salomon  Brothers also  considered
such   other  information,  financial   studies,  analyses,  investigations  and
financial, economic and market criteria as it deemed relevant.

    In  connection  with  its  review,  Salomon  Brothers  did  not  assume  any
responsibility  for independently verifying any of the foregoing information and
relied on such information being complete and accurate in all material respects.
With respect to the  financial projections, Salomon  Brothers assumed that  they
had  been reasonably prepared  on bases reflecting  the best currently available
estimates and judgments of the management of Horizon or CMS, as the case may be,
as to the future financial  performance of Horizon or CMS,  as the case may  be.
Salomon Brothers did not express any opinion with respect to such projections or
the  assumptions on  which they are  based, including  assumptions regarding the
effects of any outstanding or potential litigation, investigations, inquiries or
other actions.  In  addition,  Salomon  Brothers did  not  make  an  independent
evaluation  or appraisal of any of  the assets of Horizon or  of CMS, nor was it
furnished with  any such  appraisals.  Each of  Salomon Brothers'  opinions  was
necessarily  based upon business, market, economic  and other conditions as they
existed on, and could be evaluated as of, the respective dates of such opinions,
and does  not  address Horizon's  underlying  business decision  to  effect  the
Merger.  Salomon Brothers' opinions do not imply any conclusion as to the likely
trading range for  the Horizon Common  Stock following the  consummation of  the
Merger,  which may vary  depending on, among other  factors, changes in interest
rates, dividend rates, market conditions, general economic conditions and  other
factors that generally influence the price of securities.

   
    The  following is a summary  of the report presented  by Salomon Brothers to
the Horizon Board of Directors  on March 31, 1995  in connection with its  March
31,  1995 fairness opinion  (the "Salomon Brothers  Report"). In connection with
the Salomon  Brothers Opinion,  Salomon Brothers  performed certain  procedures,
including each of the financial analyses described below, to update its analyses
made  in  connection with  the  delivery of  its  opinion dated  March  31, 1995
(utilizing, where applicable, an  exchange ratio of  0.5397), and reviewed  with
the  managements  of Horizon  and CMS  the financial  information on  which such
analyses were based and other  factors, including the current financial  results
of  such companies  and the future  prospects for such  companies. These updated
analyses performed  by Salomon  Brothers  were not  delivered  to the  Board  of
Directors  of Horizon. The Salomon  Brothers Opinion confirmed Salomon Brothers'
opinion dated  March 31,  1995 and  thus continued  to provide  support for  the
recommendation  of the  Board of Directors  of Horizon that  the stockholders of
Horizon approve and adopt the Merger Agreement.
    

                                       38
<PAGE>
    OVERVIEW OF CMS.  Salomon Brothers reviewed the businesses of CMS (including
its latest twelve months ("LTM") revenues by business segment for the year ended
December 31, 1994).  Salomon Brothers also  reviewed CMS's historical  financial
performance  for  1992, 1993,  1994  and the  LTM,  and its  projected financial
performance for the twelve month periods  ending June 30, 1995-99 (including  in
each  case revenues,  earnings before  depreciation, interest,  amortization and
taxes ("EBDIAT"), earnings before  interest and taxes  ("EBIT"), net income  and
capital  expenditures). Salomon  Brothers compared certain  growth and operating
ratios of  CMS  (including  LTM  EBDIAT/  Revenue,  LTM  EBIT/Revenue,  LTM  Net
Income/Revenue,  LTM Historical Revenue Growth, LTM Historical EBDIAT Growth and
LTM Historical  EBIT  Growth)  to  those of  a  group  of  comparable  companies
including HEALTHSOUTH Corporation, NovaCare, Inc., Advantage Health Corporation,
Rehabcare  Corporation,  TheraTx  Incorporated and  Rehability  Corporation (the
"Comparable Group").

    DISCOUNTED CASH  FLOW ANALYSIS.    Using a  discounted cash  flow  analysis,
Salomon  Brothers estimated the present value of  the future cash flows that CMS
could produce over  a five-year  period from  1995 through  1999, under  various
assumptions,  if  CMS were  to perform  on a  stand-alone basis  (without giving
effect to  any  operating or  other  efficiencies  pursuant to  the  Merger)  in
accordance  with  management's  forecasts. Salomon  Brothers  set  forth certain
equity market value  reference ranges  for CMS  based upon  the sum  of (i)  the
aggregate  discounted value  (using various discount  rates ranging  from 10% to
14%) of the five-year unlevered free cash flows of CMS, plus (ii) the discounted
value (using various discount rates  ranging from 10% to  14%) of (a) the  final
year's  projected EBDIAT multiplied by (b) numbers representing various terminal
or exit  multiples (ranging  from  5.0x to  9.0x).  From this  analysis  Salomon
derived an equity value reference range per share of CMS Common Stock on a fully
diluted  basis from $15.00 to $18.00. Salomon Brothers also reviewed the pre-tax
value of the synergies that management  expects to achieve following the  Merger
and  performed a second discounted cash flow analysis incorporating the expected
synergies. From this analysis Salomon Brothers derived an equity value reference
range per share  of CMS Common  Stock on a  fully diluted basis  from $17.00  to
$21.00.

    COMPARABLE  COMPANY ANALYSIS.   Salomon  Brothers reviewed  and compared the
financial and  market performance  of the  Comparable Group  with that  of  CMS.
Salomon  Brothers  examined certain  publicly  available financial  data  of the
Comparable Group, including multiples  of total revenues,  EBDIAT, EBIT and  net
income,  for the latest  available twelve month  period (and in  the case of net
income, analysts'  consensus estimates  for the  twelve months  ending June  30,
1995).  Salomon  Brothers then  derived from  this data  (based on  the relative
comparability of the financial performance  of the comparable companies to  that
of  CMS) the ranges of these multiples  deemed most meaningful for its analysis,
which were as follows: total  revenues (from 82% to  94%), EBDIAT (from 7.5x  to
9.8x),  EBIT (from 9.5x to 12.7x) and  net income (from 13.0x to 20.0x). Salomon
Brothers then applied these multiples  to CMS's reported revenues, EBDIAT,  EBIT
and  net income for the twelve months  ended December 31, 1994, and management's
estimates for the twelve  months ending June  30, 1995 and, in  the case of  net
income,  also the twelve months ending June  30, 1996. This analysis resulted in
an equity value reference range per share of CMS Common Stock on a fully diluted
basis from $11.50 to $15.60.

    COMPARABLE  TRANSACTION  ANALYSIS.    Salomon  Brothers  also  reviewed  the
consideration paid or proposed to be paid in other recent transactions involving
long-term and rehabilitative health care companies and analyzed the multiples of
revenues,  EBDIAT,  EBIT and  net  income (for  the  LTM preceding  the  date of
announcement of  the  transaction and,  in  the case  of  net income,  also  the
analysts'  consensus estimates  at the time  of the announcement  for the twelve
months following the  date of  announcement of the  transaction) represented  by
such  consideration.  Specifically,  Salomon  Brothers  reviewed  the  following
acquiror/target transactions:  Sun Healthcare/CareerStaff  Unlimited  (announced
March  30, 1995),  HEALTHSOUTH/Relife (announced September  19, 1994), Multicare
Companies/Providence   Health   Care   (announced   February   2,   1994),   Sun
Healthcare/Mediplex  Group  (announced  January  4,  1994),  Regency Health/Care
Enterprises (announced December 22, 1993),

                                       39
<PAGE>
HEALTHSOUTH/Rehabilitation  Hospitals  (announced  December  6,  1993),  Genesis
Health   Ventures/   Meridian   Healthcare  (announced   September   21,  1993),
Horizon/Greenery   Rehabilitation   (announced   August   2,   1993),    Mariner
Health/Pinnacle  Care  (announced January  6,  1994) and  NovaCare/Rehab Clinics
(announced October  21, 1993).  Salomon  Brothers then  derived from  this  data
(based  on the  relative comparability  of the  transactions to  the Merger) the
ranges of the multiples deemed most  meaningful for its analysis, which were  as
follows:  total revenues (from  76% to 86%),  EBDIAT (from 7.6x  to 10.1x), EBIT
(from 9.5x to 12.3x) and net income (from 15.6x to 20.0x). Salomon Brothers then
applied the multiples derived from the comparable transactions to CMS's reported
revenues, EBDIAT, EBIT and net income  for the twelve months ended December  31,
1994, and management's estimates for the twelve months ending June 30, 1995 and,
in  the case of  net income, also the  twelve months ending  June 30, 1996. This
analysis resulted in  an equity value  reference range per  share of CMS  Common
Stock on a fully diluted basis from $11.00 to $15.40.

    PRO  FORMA MERGER CONSEQUENCES ANALYSIS.   Salomon Brothers analyzed certain
pro forma  effects  on Horizon  resulting  from  the Merger  for  the  projected
twelve-month periods ending May 31, 1995 and 1996. This analysis, based upon the
assumptions  described above  and management's  estimates of  Horizon's 1995 and
1996  stand-alone  earnings  per  share,  showed  pro  forma  dilution  to   the
stockholders  of Horizon in  earnings per share for  the projected period ending
May 31, 1995 ranging (depending on the  final exchange ratio) from 10% to  2.3%.
For  the  projected  period  ending  May  31,  1996,  the  analysis  showed  the
transaction to result in pro forma dilution or accretion to the stockholders  of
Horizon (depending on the final exchange ratio) ranging from dilution of 0.3% to
accretion  of 7.7%. No revenue or operating synergies were taken into account in
this analysis. Salomon Brothers also  performed a pro forma merger  consequences
analysis  giving effect to the synergies  that management expects to result from
the Merger. This  analysis showed  pro forma  accretion to  the stockholders  of
Horizon  in earnings  per share  for the  projected period  ending May  31, 1995
ranging (depending on  the final exchange  ratio) from 29.4%  to 40.5%. For  the
projected  period ending  May 31, 1996,  the analysis showed  the transaction to
result in pro forma accretion to  the stockholders of Horizon (depending on  the
final exchange ratio) ranging from 30.9% to 41.4%.

    In  arriving at its  opinion dated March  31, 1995 and  the Salomon Brothers
Opinion, and  in  presenting  the  Salomon  Brothers  Report,  Salomon  Brothers
performed  certain  financial  analyses,  the  material  portions  of  which are
summarized above. The summary set forth above does not purport to be a  complete
description  of Salomon Brothers'  analyses. Salomon Brothers  believes that its
analyses and the summary set forth above must be considered as a whole and  that
selecting  portions  of its  analyses  could create  an  incomplete view  of the
process underlying  the analyses  set  forth in  the  opinions and  the  Salomon
Brothers  Report.  In performing  its analyses,  Salomon Brothers  made numerous
assumptions with respect  to industry performance,  general business,  economic,
market  and financial conditions and other matters, many of which are beyond the
control of Horizon and CMS. The trading values specified in the Salomon Brothers
Report do not purport to  be indicative of actual  trading values of CMS  Common
Stock, which may be significantly more or less than the amounts set forth in the
Salomon  Brothers  Report.  Actual  values  will  depend  upon  several factors,
including events  affecting the  rehabilitative  health care  industry,  general
economic,  market and interest rate conditions and other factors which generally
influence the price of securities.

    No company used in the comparable company analysis nor any transaction  used
in  the comparable transaction analysis summarized  above is identical to CMS or
the Merger, respectively.  Accordingly, any such  analysis of the  value of  the
proposed   Merger  involves  complex  considerations  and  judgments  concerning
differences in  the potential  financial and  operating characteristics  of  the
comparable   companies  and  other  factors  in  relation  to  the  trading  and
acquisition  values  of   the  comparable  companies   and  publicly   announced
transactions.

    Salomon  Brothers is  an internationally recognized  investment banking firm
and regularly engages  in the valuation  of businesses and  their securities  in
connection  with mergers  and acquisitions and  for other  purposes. The Horizon
Board of Directors selected Salomon Brothers to act as its financial advisor  on
the basis of Salomon Brothers' international reputation and its familiarity with

                                       40
<PAGE>
Horizon  and CMS and the  health care industry in general.  In the course of its
business, Salomon Brothers actively trades the securities of Horizon and CMS for
its own account and for the accounts of customers. Accordingly, Salomon Brothers
may at any time hold a long or short position in such securities.

    FEES PAID TO SALOMON BROTHERS.  Horizon has paid Salomon Brothers  aggregate
fees of $250,000 in consideration for Salomon Brothers' services. Such fees were
payable  regardless of  the outcome of  Salomon Brothers'  opinions. Horizon has
also agreed  to  reimburse  Salomon Brothers  for  its  out-of-pocket  expenses,
including  reasonable fees and  disbursements of counsel.  Horizon has agreed to
indemnify Salomon  Brothers, and  its  affiliates, their  respective  directors,
officers,  partners, agents and  employees and each  person, if any, controlling
Salomon Brothers or any of its affiliates against certain liabilities, including
certain liabilities under the  federal securities laws,  relating to or  arising
out of its engagement.

CMS
    On  March 31, 1995, Merrill Lynch delivered its oral opinion to the Board of
Directors of CMS, which opinion was subsequently confirmed in writing, that,  as
of  such date and based upon the assumptions made and matters considered in, and
the limitations  on, the  review  undertaken by  Merrill  Lynch as  reviewed  by
Merrill   Lynch  with  the  Board  of  Directors  of  CMS,  the  exchange  ratio
contemplated by the Merger Agreement was fair to the stockholders of CMS from  a
financial  point of view. Merrill Lynch subsequently delivered the Merrill Lynch
Opinion dated as of the date  of this Joint Proxy Statement/Prospectus that,  as
of  such date and based  on the assumptions made  and matters considered in, and
the limitations on, the review undertaken by  Merrill Lynch as set forth in  the
Merrill  Lynch Opinion, the Exchange  Ratio was fair to  the stockholders of CMS
from a financial point of view. A copy of the Merrill Lynch Opinion, which  sets
forth  the assumptions made  and matters considered in,  and the limitations on,
the review undertaken by Merrill Lynch, is attached as Appendix C to this  Joint
Proxy  Statement/Prospectus. The summary of the  Merrill Lynch Opinion set forth
in this  Joint  Proxy  Statement/Prospectus  is qualified  in  its  entirety  by
reference  to  the full  text of  such opinion.  The March  31, 1995  opinion is
substantially similar  to the  Merrill Lynch  Opinion. STOCKHOLDERS  OF CMS  ARE
URGED TO READ THE MERRILL LYNCH OPINION IN ITS ENTIRETY.

    The  Merrill Lynch Opinion is directed only  to the fairness of the Exchange
Ratio to the stockholders  of CMS from  a financial point of  view and does  not
constitute  a recommendation to  any CMS stockholder as  to how such stockholder
should vote at the CMS Special  Meeting. The exchange ratio contemplated by  the
Merger Agreement was determined through negotiations between Horizon and CMS and
was  approved by the Board of Directors of CMS. Merrill Lynch provided advice to
CMS during the course  of such negotiations, but  did not make a  recommendation
with respect to the exchange ratio contemplated by the Merger Agreement.

   
    In arriving at the Merrill Lynch Opinion, Merrill Lynch, among other things:
(i)  reviewed CMS's Annual Reports, Forms 10-K and related financial information
for the five fiscal  years ended June  30, 1994 (and, with  respect to the  Form
10-K  for the fiscal year ended June  30, 1994, the amendment thereto) and CMS's
Forms 10-Q and  the related  unaudited financial information  for the  quarterly
periods  ended September 30, 1994, December 31, 1994 and March 31, 1995 (and the
amendments thereto),  (ii) reviewed  Horizon's Annual  Reports, Forms  10-K  and
related  financial information for the five fiscal years ended May 31, 1994 (and
the amendments  thereto) and  Horizon's  Forms 10-Q  and the  related  unaudited
financial  information for the quarterly periods ended August 31, 1994, November
30, 1994 and  February 28,  1995 (and  the amendments  thereto); (iii)  reviewed
certain  information, including  financial forecasts, relating  to the business,
earnings, cash  flow, assets  and prospects  of CMS  and Horizon,  furnished  to
Merrill  Lynch by  CMS and Horizon;  (iv) conducted discussions  with members of
senior management of CMS and Horizon concerning their respective businesses  and
prospects;  (v) reviewed certain  information furnished to  Merrill Lynch by CMS
and conducted discussions with members of  senior management of CMS and  Horizon
concerning  potential synergies to be  realized as a result  of the Merger; (vi)
reviewed the  historical  market prices  and  trading activity  for  outstanding
shares  of CMS Common Stock  and outstanding shares of  Horizon Common Stock and
    

                                       41
<PAGE>
compared them with that of certain publicly traded companies which Merrill Lynch
deemed to be reasonably similar to CMS and Horizon, respectively; (vii) compared
the results of  operations of  CMS and Horizon  with that  of certain  companies
which  Merrill  Lynch  deemed  to  be reasonably  similar  to  CMS  and Horizon,
respectively; (viii) compared the proposed  financial terms of the  transactions
contemplated  by the Agreement with the financial terms of certain other mergers
and acquisitions which Merrill  Lynch deemed to be  relevant; (ix) reviewed  the
Merger  Agreement; (x)  reviewed the Stock  Option Agreement;  (xi) reveiwed the
Voting Agreement; and (xii) reviewed  such other financial studies and  analyses
and performed such other investigations and took into account such other matters
as Merrill Lynch deemed necessary, including its assessment of general economic,
market and monetary conditions.

    In  preparing  the  Merrill Lynch  Opinion,  Merrill Lynch  relied  upon the
accuracy  and  completeness  of  all  information  supplied  or  otherwise  made
available  to it  by CMS  and Horizon, and  Merrill Lynch  did not independently
undertake an independent appraisal or evaluation of the assets or liabilities of
CMS or  Horizon.  With respect  to  financial  forecasts furnished  by  CMS  and
Horizon,  Merrill Lynch assumed that they were reasonably prepared and reflected
the best currently available estimates and judgment of the management of CMS  or
Horizon  as to the expected  future financial performance of  CMS or Horizon, as
the case may be. Moreover, with respect to the estimates of potential  synergies
furnished  by CMS, Merrill Lynch assumed  that they were reasonably prepared and
reflected the best currently available estimates and judgment of the  management
of  CMS as to the potential synergies to  be realized as a result of the Merger.
Merrill Lynch also assumed that the Merger will qualify for pooling-of-interests
accounting treatment and as a tax-free transaction for the stockholders of CMS.

    In connection with  the preparation  of the Merrill  Lynch Opinion,  Merrill
Lynch was not authorized by CMS or its Board of Directors to solicit, nor did it
solicit,  third-party indications of interest for  the acquisition of all or any
part of CMS.

    The following is a summary of certain analyses performed by Merrill Lynch in
connection with its opinion dated March 31, 1995. In connection with the Merrill
Lynch Opinion, Merrill Lynch performed certain procedures, including each of the
financial analyses described below,  to update its  analyses made in  connection
with  the  delivery  of  its  opinion dated  March  31,  1995  (utilizing, where
applicable, an exchange ratio of 0.5397),  and reviewed with the managements  of
Horizon  and CMS the financial information on which such analyses were based and
other factors, including the current financial results of such companies and the
future prospects for such companies. These updated analyses performed by Merrill
Lynch were not delivered  to the Board  of Directors of  CMS. The Merrill  Lynch
Opinion  confirmed  Merrill  Lynch's  opinion  dated  March  31,  1995  and thus
continued to provide support for the recommendation of the Board of Directors of
CMS that the stockholders of CMS approve and adopt the Merger Agreement.

    DISCOUNTED CASH FLOW ANALYSIS  -- CMS.  Merrill  Lynch calculated ranges  of
equity  value for CMS  based upon the  value, discounted to  the present, of its
fiscal year end five-year stream of  unlevered after-tax free cash flow and  its
projected fiscal year 2000 terminal value based upon a range of multiples of its
projected  fiscal year  2000 earnings  before interest,  taxes, depreciation and
amortization ("EBITDA"). In conducting its analysis, Merrill Lynch utilized  the
CMS  Base Case and also  developed a sensitivity analysis  based on the CMS Base
Case (the  "CMS  Conservative  Case"), which  assumed  a  consolidated  compound
average  annual revenue growth of 4.6% and  average EBITDA margins of 11.6%. See
"-- Certain  Information  Provided."  In  both  cases,  Merrill  Lynch  utilized
discount  rates reflecting a weighted average cost of capital ranging from 11.5%
to 15.5% and terminal  value multiples of fiscal  year 2000 EBITDA ranging  from
5.0x  to 8.0x. Based on this analysis, Merrill Lynch calculated a range of value
of between $10.00 and $16.00 per share of CMS Common Stock based on the CMS Base
Case, and of between $6.75 and $11.50 per share of CMS Common Stock based on the
CMS Conservative Case.

    DISCOUNTED CASH FLOW ANALYSIS --  HORIZON.  Merrill Lynch calculated  ranges
of  equity value for Horizon based upon the value, discounted to the present, of
its five-year stream of unlevered after-tax

                                       42
<PAGE>
free cash flow and  its fiscal year  2000 terminal value based  upon a range  of
multiples  of its  projected fiscal year  2000 earnings  before interest, taxes,
depreciation,  amortization  and  rent   expenses  for  hospitals  and   similar
facilities  ("EBITDAR"). In conducting its  analysis, Merrill Lynch utilized the
Horizon Base Case, which assumed a consolidated compound average annual  revenue
growth  of  19.5%  and  average  EBITDAR  margins  of  20.7%.  See  "--  Certain
Information Provided."  In  addition,  Merrill  Lynch  developed  a  sensitivity
analysis based on the Horizon Base Case (the "Horizon Conservative Case"), which
assumed  a  consolidated compound  average annual  revenue  growth of  16.5% and
average EBITDAR margins of 20.7%. In both cases, Merrill Lynch utilized discount
rates reflecting a weighted average cost of capital ranging from 14.0% to  18.0%
and  terminal value multiples of  fiscal year 2000 EBITDAR  ranging from 8.0x to
11.0x. Based on  this analysis,  Merrill Lynch calculated  a range  of value  of
between $25.75 and $40.00 per share of Horizon Common Stock based on the Horizon
Base  Case, and of between  $19.50 and $31.75 per  share of Horizon Common Stock
based on the Horizon Conservative Case.

    Merrill Lynch also calculated ranges of equity value for Horizon based  upon
a  discounted  cash flow  analysis for  each of  the Horizon  Base Case  and the
Horizon Conservative Case assuming that annual savings from synergies  projected
by  the  managements  of  CMS  and  Horizon  as  a  result  of  the  Merger (the
"Synergies") would be achieved. Based on this analysis, Merrill Lynch calculated
that the Horizon  Base Case indicated  a range  of value of  between $31.00  and
$46.50  per share  of Horizon  Common Stock,  and the  Horizon Conservative Case
indicated a range of  value of between  $24.75 and $38.50  per share of  Horizon
Common Stock.

    SEGMENT  DISCOUNTED CASH  FLOW ANALYSIS  -- CMS.   Merrill  Lynch calculated
ranges of equity value for CMS based upon the value, discounted to the  present,
of  its five-year stream of unlevered after-tax free cash flow and a fiscal year
2000 terminal value  based upon a  range of multiples  of projected fiscal  year
2000   EBITDA   for  CMS's   medical   rehabilitation  hospital   business  (the
"Rehabilitation Hospital  Group") and  contract therapy  and physician  services
business  (the "Contract Therapy  and Physician Services  Group"). Merrill Lynch
analyzed each segment based on both the  CMS Base Case and the CMS  Conservative
Case.  In  both  cases, for  the  Rehabilitation Hospital  Group,  Merrill Lynch
utilized discount rates ranging from 12.0% to 14.0% and terminal value multiples
of fiscal year 2000  EBITDA ranging from  5.0x to 8.0x. In  both cases, for  the
Contract  Therapy and Physician Services Group,  taken as a whole, Merrill Lynch
utilized discount rates ranging from 10.0% to 14.0% and terminal value multiples
of fiscal year 2000 EBITDA  ranging from 6.5x to  9.5x. Based on this  analysis,
Merrill Lynch calculated a range of value of between $11.50 and $16.50 per share
of  CMS Common Stock based on the CMS Base  Case and a range of value of between
$7.50 and $11.75 per  share of CMS  Common Stock based  on the CMS  Conservative
Case.

    ANALYSIS  OF SELECTED COMPARABLE PUBLICLY TRADED  COMPANIES -- CMS.  Merrill
Lynch compared  certain publicly  available historical  financial and  operating
data  and projections of future financial performance (reflecting a composite of
research analysts'  estimates)  of  Advantage  Health  Corporation,  HEALTHSOUTH
Corporation,  NovaCare, Inc.,  RehabCare Corporation  and Rehability Corporation
(collectively, the  "Rehabilitation  and Contract  Services  Comparables")  with
similar   historical  financial  and  operating  data  and  projected  financial
performance of CMS which was provided to Merrill Lynch by the management of CMS.
Merrill Lynch compared  the market value  as multiples of  fiscal 1995 and  1996
estimated  earnings per share  ("EPS") (which were obtained  from First Call and
were arithmetically adjusted by Merrill Lynch to reflect a December 31 year end)
and compared  market capitalization  as  a multiple  of publicly  reported  last
twelve months ("LTM") EBITDA and publicly reported LTM revenues. For purposes of
this analysis, Merrill Lynch defined market value as the closing price per share
on  March 24,  1995 multiplied  by the number  of shares  outstanding and market
capitalization as the  market value  plus liquidation value  of preferred  stock
plus  total  debt  and  minority  interests  less  cash,  cash  equivalents  and
marketable securities. Merrill  Lynch determined  that these  multiples were  as
follows:  (i) market value to estimated fiscal year 1995 estimated EPS was 14.4x
for  CMS  compared  to  those  of  the  Rehabilitation  and  Contract   Services
Comparables,  which ranged from  11.2x to 18.8x; (ii)  market value to estimated
fiscal year 1996 estimated EPS was 10.4x

                                       43
<PAGE>
for  CMS  compared  to  those  of  the  Rehabilitation  and  Contract   Services
Comparables, which ranged from 8.4x to 15.0x; (iii) market capitalization to LTM
EBITDA  was 8.7x for  CMS compared to  those of the  Rehabilitation and Contract
Services  Comparables,  which  ranged  from  6.1x  to  11.1x;  and  (iv)  market
capitalization  to  LTM revenues  was 0.59x  for  CMS compared  to those  of the
Rehabilitation and Contract  Services Comparables,  which ranged  from 0.62x  to
2.29x.  Based  on  the  foregoing ranges  for  the  Rehabilitation  and Contract
Services Comparables,  as  well  as Merrill  Lynch's  experience  in  evaluating
publicly  traded companies, Merrill Lynch calculated that the Rehabilitation and
Contract Services Comparables indicated a range of value of CMS ranging  between
$6.00 and $13.00 per share of CMS Common Stock.

    ANALYSIS    OF   SELECTED   COMPARABLE    PUBLICLY   TRADED   COMPANIES   --
HORIZON.   Merrill  Lynch  compared certain  publicly  available  financial  and
operating  data and  projections of  future financial  performance (reflecting a
composite of research analysts' estimates) of Beverly Enterprises, Inc., Genesis
Health Ventures, Inc.,  Health Care  and Retirement  Corporation, The  Hillhaven
Corporation,  Integrated Health Services, Inc., Living Centers of America, Inc.,
Manor Care, Inc., The  Multicare Companies, and Sun  Healthcare Group Inc.  (the
"Long-Term  Care Comparables -- Group A"), as well as Arbor Health Care Company,
GranCare, Inc., Mariner  Health Group,  Inc. and Regency  Health Services,  Inc.
(the  "Long-Term Care Comparables  -- Group B" and,  together with the Long-Term
Care Comparables  -- Group  A, the  "Long-Term Care  Comparables") with  similar
historical  financial  and operating  data and  projections of  future financial
performance of Horizon. Merrill Lynch compared the market value as multiples  of
fiscal 1995 and 1996 estimated EPS (which were obtained from First Call and were
arithmetically adjusted by Merrill Lynch to reflect a December 31 year end), and
compared  market  capitalization plus  eight  times the  LTM  rent expense  as a
multiple of publicly reported LTM EBITDAR as well as market capitalization as  a
multiple  of publicly  reported LTM  revenues. Merrill  Lynch also  analyzed the
estimated five year  EPS growth  rates (which were  obtained from  Institutional
Brokerage  Estimate  Service)  for  Horizon  and  each  of  the  Long-Term  Care
Comparables. Merrill Lynch determined that these multiples were as follows:  (i)
market  value to estimated fiscal year 1995  estimated EPS was 19.1x for Horizon
compared to those of the Long-Term Care Comparables, which ranged from 10.7x  to
20.6x;  (ii) market value to estimated fiscal  year 1996 estimated EPS was 15.3x
for Horizon compared to  those of the Long-Term  Care Comparables, which  ranged
from  9.3x to 17.5x; (iii)  market capitalization plus eight  times LTM rents to
LTM EBITDAR  was 11.8x  for Horizon  compared  to those  of the  Long-Term  Care
Comparables,  which ranged from 7.8x to 12.8x; (iv) market capitalization to LTM
revenues was  1.65x  for  Horizon  compared  to  those  of  the  Long-Term  Care
Comparables,  which ranged from 0.31x to 3.43x;  and (v) estimated five year EPS
growth rate  was 24.9%  for Horizon  compared  to those  of the  Long-Term  Care
Comparables, which ranged from 14.9% to 30.0%. Based on the foregoing ranges for
the  Long-Term  Care  Comparables,  as well  as  Merrill  Lynch's  experience in
evaluating  publicly  traded  companies,  Merrill  Lynch  calculated  that   the
Long-Term  Comparables indicated a  range of value of  between $25.00 and $30.00
per share of Horizon Common Stock.

    No company utilized in the comparable publicly traded companies analysis was
identical to CMS or Horizon. Accordingly, an  analysis of the results of such  a
comparison   is   not   purely  mathematical;   rather,   it   involves  complex
considerations and judgments concerning differences in historical and  projected
financial  and operating characteristics  of the comparable  companies and other
factors that could affect the public  trading value of the comparable  companies
or company to which they are being compared.

    ANALYSIS  OF SELECTED  COMPARABLE ACQUISITION  TRANSACTIONS.   Merrill Lynch
reviewed certain publicly available information regarding ten selected  business
combinations  involving  companies involved  in  the medical  rehabilitation and
contract services business  announced since October  25, 1991 (the  "Acquisition
Comparables").  The Acquisition Comparables  included: HEALTHSOUTH Corporation's
acquisition  of  the  rehabilitation   hospital  division  of  NovaCare,   Inc.;
HEALTHSOUTH    Corporation's   acquisition   of    ReLife,   Inc.;   HEALTHSOUTH
Rehabilitation Corporation's acquisition of selected rehabilitation hospitals of
National  Medical   Enterprises,   Inc.;   NovaCare,   Inc.'s   acquisition   of

                                       44
<PAGE>
RehabClinics,  Inc.;  NovaCare,  Inc.'s acquisition  of  Rehabilitation Hospital
Corp.; RehabCare Corporation's acquisition of Advanced Rehabilitation Resources,
Inc.; ReLife,  Inc.'s  acquisition  of  Rebound  Inc.;  National  Rehabilitation
Centers,  Inc.'s acquisition  of Healthfocus,  Inc.; ReLife  Acquisition Corp.'s
acquisition of American Health Resources,  Inc.; and ReLife, Inc.'s  acquisition
of Renaissance America, Inc.

    Merrill  Lynch compared  the transaction  value (which  it defined  for this
purpose as (i) the offer price per share multiplied by the sum of the number  of
shares  outstanding and the number of  exercisable options outstanding plus (ii)
the liquidation value  of preferred  stock plus  (iii) total  debt and  minority
interests  less (iv) cash, cash equivalents  and proceeds received upon exercise
of options) of each such transaction as a multiple of the publicly available LTM
EBITDA. The  range  of  multiples  for the  Acquisition  Comparables,  based  on
transaction value to LTM EBITDA, ranged from 2.4x to 9.9x.

    Merrill  Lynch then calculated aggregate and per share imputed equity values
of CMS Common Stock by applying CMS's actual and forecasted financial results to
the multiples derived from its analysis of the Acquisition Comparables described
above. Based  on its  analysis,  Merrill Lynch  concluded that  the  Acquisition
Comparables indicated a range of values of between $9.00 and $17.00 per share of
CMS Common Stock.

    No  company  utilized in  the Selected  Comparable Acquisition  Analysis was
identical to CMS. Accordingly, an analysis of the results of this comparison  is
not   purely  mathematical;  rather,  it  involves  complex  considerations  and
judgments concerning  differences  in  historical and  projected  financial  and
operating characteristics of the comparable acquired companies and other factors
that could affect the acquisition value of such companies and CMS.

    RELATIVE  EXCHANGE RATIO ANALYSIS.  Merrill Lynch utilized a discounted cash
flow methodology to compare implied exchange ratios based on relative ranges  of
value  for CMS and Horizon.  The comparison of the CMS  Base Case to the Horizon
Base Case  (without Synergies)  yielded  an implied  exchange ratio  of  between
0.2532  and 0.6188 shares of  Horizon Common Stock for  each share of CMS Common
Stock. The comparison of the CMS  Conservative Case to the Horizon  Conservative
Case (without Synergies) yielded an implied exchange ratio of between 0.2130 and
0.5934  shares of Horizon Common  Stock for each share  of CMS Common Stock. The
comparison of  the CMS  Base Case  to  the Horizon  Base Case  (with  Synergies)
yielded an implied exchange ratio of between 0.2170 and 0.5132 shares of Horizon
Common  Stock for  each share  of CMS  Common Stock.  The comparison  of the CMS
Conservative Case to the Horizon  Conservative Case (with Synergies) yielded  an
implied  exhange ratio  of between  0.1761 and  0.4665 shares  of Horizon Common
Stock for each share of CMS Common Stock.

    Merrill Lynch then utilized a comparable publicly traded company analysis to
compare implied exchange ratios  based on relative ranges  of value for CMS  and
Horizon.  The comparison  of values  imputed for CMS  to the  values imputed for
Horizon yielded an implied exchange ratio of between 0.2000 and 0.5200 shares of
Horizon Common Stock for each share of CMS Common Stock.

    CONTRIBUTION ANALYSIS.  Merrill Lynch  also compared the relative  ownership
of  the stockholders  of CMS and  the stockholders  of Horizon of  the pro forma
combined operations of 40.0% and 60.0% (based on an exchange ratio of 0.4906) to
the relative contributions of CMS to  the pro forma combined operations for  the
years  ending May  1996, 1997  and 1998  to net  sales, EBITDAR,  EBIT and fully
diluted net  income. Based  on  the CMS  Base Case  and  the Horizon  Base  Case
(without  Synergies), CMS would  contribute to the  combined operations, for the
years ending May  1996, 1997  and 1998,  respectively, (a)  an estimated  56.3%,
53.6%  and  51.1% of  net  sales; (b)  an estimated  53.1%,  50.5% and  47.8% of
EBITDAR; (c) an estimated 49.7%, 47.8% and  45.2% of EBIT; and (d) an  estimated
43.0%, 43.8% and 43.0% of fully-diluted net income.

    PRO  FORMA ANALYSIS.   Merrill  Lynch analyzed  the potential  impact of the
Merger on the  estimated EPS  of CMS and  Horizon, respectively,  for the  years
1996-1999, assuming that the Merger will qualify

                                       45
<PAGE>
for  pooling-of-interests  accounting  treatment  in  both  the  case  where the
Synergies would  be achieved  and the  case  where the  Synergies would  not  be
achieved  (based on  an exchange ratio  of 0.4906). Merrill  Lynch also analyzed
certain pro forma effects on the estimated EPS of CMS and Horizon, respectively,
that could occur if the Merger were not consummated. Based on the CMS Base  Case
and the Horizon Base Case, the analysis indicated that for a holder of shares of
CMS Common Stock, the Merger would be accretive on an estimated EPS basis in the
amount  of 8.6% for the fiscal  year 1996, in the amount  of 5.9% for the fiscal
year 1997, in the amount of 7.4% for  the fiscal year 1998 and in the amount  of
9.0%  for the fiscal year  1999. Assuming the same  cases as above, the analysis
indicated that for a holder of shares of Horizon Common Stock, the Merger  would
be  accretive in the amount of 23.8% in fiscal year 1996, in the amount of 23.7%
in fiscal year 1997 and in the amount of 20.9% in fiscal year 1998. Assuming the
same cases as above,  but without Synergies, the  analysis indicated that for  a
holder  of Horizon Common Stock, the Merger  would be accretive in the amount of
6.6% in fiscal year 1996, in the amount  of 8.6% in fiscal year 1997 and in  the
amount  of 7.8% in fiscal year 1998. Based  on the CMS Conservative Case and the
Horizon Base  Case projections,  the analysis  indicated that  for a  holder  of
shares  of Horizon Common Stock, the  Merger, with Synergies, would be accretive
in the amount of  14.4% in fiscal year  1996, in the amount  of 12.7% in  fiscal
year  1997 and in  the amount of 9.3%  in fiscal year 1998.  If no Synergies are
assumed, the analysis  assuming the same  cases indicated that  for a holder  of
shares  of Horizon Common Stock, the Merger  would be dilutive in the amounts of
2.8%, 2.4% and 3.9% in fiscal years 1996-1998, respectively.

    HISTORICAL STOCK PRICE ANALYSIS.  Merrill Lynch reviewed the per share daily
closing market price of CMS Common Stock over the period from March 24, 1994  to
March  30, 1995 compared with the performance of the Standard & Poor's 500 Index
and a composite index of  the Rehabilitation and Contract Services  Comparables.
Merrill  Lynch  also reviewed  the performance  of the  per share  daily closing
market price of  Horizon Common Stock  over the  period from March  24, 1994  to
March 30, 1995 compared with the movement of the Standard & Poor's 500 Index and
a composite index of the Long-Term Care Comparables -- Group A.

    The summary set forth above does not purport to be a complete description of
the  analyses performed by Merrill Lynch. In arriving at its opinion dated March
31, 1995, Merrill Lynch performed a variety of financial analyses, the  material
portions of which are summarized above. In addition, Merrill Lynch believes that
its  analyses must be considered  as a whole and  that selecting portions of its
analyses and  of the  factors considered  by it,  without considering  all  such
factors  and analyses, could create a  misleading view of the process underlying
its  opinions.  In  performing  its   analyses,  Merrill  Lynch  made   numerous
macroeconomic,  operating  and financial  assumptions  with respect  to industry
performance, general business and economic conditions and other matters, many of
which are beyond CMS's or Horizon's  control. Any estimates incorporated in  the
analyses  performed by  Merrill Lynch are  not necessarily  indicative of actual
past or  future results  or values,  which  may be  significantly more  or  less
favorable  than such estimates. Estimated values do not purport to be appraisals
and do not necessarily reflect the  prices at which businesses or companies  may
be sold in the future, and such estimates are inherently subject to uncertainty.
The  preparation  of a  fairness opinion  is a  complex process  not necessarily
susceptible to partial or summary description. Merrill Lynch did not assign  any
relative weights to any of its analyses in preparing its opinion.

    As  part of  its investment banking  business, Merrill  Lynch is continually
engaged in the valuation of businesses  and their securities in connection  with
mergers  and acquisitions. The Board of  Directors of CMS selected Merrill Lynch
to act as  its financial  advisor because  Merrill Lynch  is an  internationally
recognized  investment banking firm with  substantial experience in transactions
similar to the Merger and because it is familiar with CMS and its business.

    Merrill Lynch has rendered from time to time various investment banking  and
financial  advisory  services to  Horizon for  which  it has  received customary
compensation. In the  ordinary course  of business, Merrill  Lynch may  actively
trade the securities of both CMS and Horizon for its own account and the account
of its customers and, accordingly, may at any time hold a long or short position
in such securities.

    For  its financial advisory services in  connection with the Merger, CMS has
agreed to pay Merrill Lynch  a fee of $500,000 upon  the execution on March  31,
1995  of the Merger Agreement and has  agreed to pay Merrill Lynch an additional
fee of 0.5% of the aggregate purchase price paid in the Merger at the  Effective
Time (against which the $500,000 fee will credited). In addition, CMS has agreed
to reimburse Merrill Lynch for its reasonable out-of- pocket expenses (including
reasonable  fees and  expenses of  its legal  counsel) and  to indemnify Merrill
Lynch  and  certain  related  persons  against  certain  liabilities,  including
liabilities under securities laws, arising out of its engagement.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

    In  considering the recommendation of CMS's  Board of Directors with respect
to the Merger, CMS's stockholders should be aware that certain members of  CMS's
Board  and management have certain interests respecting the Merger separate from
their interests as holders of CMS  Common Stock, including those referred to  in
"-- Employment Arrangements;" "-- Board Arrangements;" and "Certain Terms of the
Merger Agreement -- Indemnification."

    In  addition, Mr.  Neal M. Elliott,  Horizon's Chairman  and Chief Executive
Officer, beneficially owned 15,000 shares of CMS Common Stock at March 31, 1995.
Of these shares,  10,000 shares  were acquired in  the aggregate  on January  25
through  January 26, 1995, for an  average purchase price of approximately $4.74
per share, and 5,000 shares  were acquired on February  23, 1995 for $5.875  per
share.  Mr. Elliott acquired these shares in ordinary brokerage transactions. On
April 12, 1995,  Mr. Elliott sold  to CMS 5,000  shares of CMS  Common Stock  at
$5.875  per share (an aggregate of $29,375),  representing the price paid by Mr.
Elliott in his February purchase. The closing  price of the CMS Common Stock  on
the  NYSE Composite  Tape on April  11, 1995  was $11.00 per  share. Pursuant to
these arrangements, no profit was realized with respect to such 5,000 shares  by
Mr.  Elliott in order to eliminate any  question concerning the propriety of the
purchase of  shares  by  him  in February.  To  Horizon's  knowledge,  no  other
executive officer or director of Horizon owns any shares of CMS Common Stock.

EMPLOYMENT ARRANGEMENTS

    At  the Effective Time, Mr. Rocco  A. Ortenzio, Chairman and Chief Executive
Officer of CMS, will become a director  and Vice Chairman of Horizon's Board  of
Directors.  At that time,  he will cease to  be an employee of  CMS and will not
become an  employee  of Horizon.  Mr.  Rocco Ortenzio  has  agreed to  become  a
director and Vice Chairman of Horizon's Board of Directors following the Merger,
and  to provide consulting services  to Horizon on an hourly  basis at a rate of
$300 per hour. Mr. Rocco Ortenzio's  employment agreement with CMS, under  which
he agreed to serve as CMS's Chairman and Chief Executive Officer, provides for a
base  salary  of  $400,000  per  year and  also  provides  for  additional bonus
compensation of 3% of CMS's consolidated pre-tax income (excluding extraordinary
gains, losses  or charges)  in excess  of $2.5  million per  fiscal year.  If  a
"change  in control"  of CMS  occurs and  within one  year thereafter  Mr. Rocco
Ortenzio's services are terminated for any  reason other than for "cause" or  if
he  terminates his employment for  "good reason" (as these  terms are defined in
his employment agreement), his bonus payments would continue until December  31,
1998, the remainder of the contract term, and CMS would also be obligated to pay
him  an amount equal to his cash  compensation for the preceding three years or,
if less, three times  his average annual cash  compensation for the five  fiscal
years  prior to the  change in control.  The Merger will  constitute a change in
control for purposes of this employment agreement.

    In evaluating the Merger,  the Horizon Board of  Directors and CMS Board  of
Directors   recognized  that  Mr.  Rocco  Ortenzio's  bonus  arrangement  would,
following the  Merger, require  that  CMS's current  operations continue  to  be
accounted  for separately, which would be impractical in light of the companies'
plans to realize many of the  significant opportunities presented by the  Merger
by  combining certain  aspects of  their respective  businesses. Accordingly, in
order  to  remove  the  impediment  that  these  contractual  obligations  might
otherwise  have on future operations, Mr. Rocco  Ortenzio agreed on the value to
be ascribed to the provisions relating  to the termination without cause of  his
employment  arrangements with CMS,  including the bonus,  in connection with the
Merger. The terms of the

                                       47
<PAGE>
agreement, which  were reviewed  and approved  by the  CMS Board  of  Directors,
provide  that  following the  Merger Mr.  Rocco  Ortenzio would  cease to  be an
employee of CMS  and would receive  $3.7 million in  satisfaction of his  rights
under the change in control provisions described above and would also receive up
to  $11.6 million in  lieu of a bonus  for periods after the  Merger and for his
agreement to enter  into a mutually  acceptable non-compete agreement,  provided
that  an independent  third party  agreed that  the present  value of  the bonus
equalled or exceeded  such amount. The  present value of  Mr. Ortenzio's  future
bonus  payments was determined by projecting the future operating results of CMS
through the  remaining  term  of his  employment  agreement.  These  projections
included   an  average  annual  revenue  growth  of  approximately  7%  with  an
improvement  in  the  operating  margin  over  the  term  of  the  agreement  of
approximately  10%. The  projections also  took into  account anticipated future
benefit of CMS's  recent restructuring  measures as well  as anticipated  future
benefit  bo be derived by CMS because of the merger. The projections contemplate
that CMS will minimize  its interest expense by  using substantially all  excess
cash  it  generates  to  repay  indebtedness  including  continued  open  market
repurchases of  its  Senior  Subordinated Notes.  Under  these  assumptions  Mr.
Ortenzio's  potential  bonus  is  approximately  $14.5  million.  An independent
benefits consultant actuarially valued and discounted (at 7.50%) this amount  to
a  current value of approximately $12.2 million. The payment for terminating the
annual bonus was capped at $11.6 million  less any amounts to be paid under  the
non-competition  agreement.  In addition,  pursuant  to his  existing employment
arrangements with CMS, Rocco Ortenzio's outstanding unvested options to purchase
800,000 shares of CMS Common Stock (which by virtue of the Merger will have been
converted into options to purchase shares  of Horizon Common Stock based on  the
Exchange  Ratio)  will  become  fully  vested.  Horizon  has  agreed  that Rocco
Ortenzio's existing CMS  term life  insurance policy  will be  converted into  a
whole  life policy pursuant to a split-dollar  arrangement with CMS prior to the
Effective Time.

    At the Effective  Time, Robert  A. Ortenzio, President  and Chief  Operating
Officer  of CMS will become Executive Vice  President of Horizon and a member of
its Board  of Directors.  At that  time, he  will enter  into a  new  employment
agreement  (the  "Employment  Agreement")  with  Horizon  containing  terms  and
conditions (including  current salary)  substantially similar  to those  in  his
existing  employment agreement with CMS.  This agreement will be  in lieu of his
existing arrangements and  agreements with  CMS. The  Employment Agreement  will
also  provide for a retirement benefit equal  to 5% of Robert Ortenzio's highest
annual base salary during his employment by Horizon multiplied by his number  of
years  of service,  determined as  described below.  This retirement  benefit is
subject to a  maximum of  50% of Robert  Ortenzio's highest  annual base  salary
during his employment with Horizon, reduced by all amounts payable under federal
social   security  or  any  Horizon  retirement   plan.  For  purposes  of  this
calculation, Robert Ortenzio will be granted full credit for service retroactive
to March 1986. The Employment Agreement will also provide for a death benefit to
the surviving spouse or  minor children in  an amount equal  to one-half of  the
retirement benefit payable at his death (whether before or after retirement). In
addition,  the Employment Agreement  will provide for  disability benefits in an
amount equal to 50%  of the annual  base salary at the  time of any  disability,
reduced  by  any  disability  insurance  benefits  paid.  Under  the  Employment
Agreement,  disability  payments  will  be  payable  until  recovery  from   the
disability  or until  he reaches age  65. The Employment  Agreement will provide
that, upon termination of  the agreement (i) by  Horizon without cause, (ii)  by
Robert  Ortenzio after 18 months following the Effective Time or (iii) by Robert
Ortenzio prior to such date but after a material diminution or limitation of his
duties and powers  or demotion or  removal from  the Board of  Directors, or  in
certain   other  circumstances,  Robert  Ortenzio  will  receive  severance  pay
generally equal to  the aggregate  of his  cash compensation  for the  preceding
three  years. In addition to such severance compensation, all options, warrants,
stock bonuses and similar awards held by Robert Ortenzio will immediately  vest.
Upon  termination by Horizon  for cause or termination  by Robert Ortenzio under
any other circumstances, Robert Ortenzio will receive no severance compensation.

                                       48
<PAGE>
    Each of  CMS's other  senior executive  officers is  a party  to  previously
existing  change  in control  agreement with  CMS which,  following a  change of
control of CMS (which as defined in these agreements will occur as a consequence
of the Merger),  provides for  severance payments equal  to approximately  three
times  his or  her average  annual cash  compensation from  CMS during  the five
preceding taxable  years  (or,  if  such individual  was  not  employed  by  CMS
throughout  such period, the period during which he or she was so employed) upon
a termination of employment  without cause or  resignation following a  material
limitation   of  the  individual's   duties  and  power   or  in  certain  other
circumstances. If such  terminations of  employment occur  following the  Merger
with  respect  to any  of  these officers,  such  officer would  be  entitled to
payments in the following approximate  amounts: Frank Fritsch, $595,000;  Dennis
Lehman,  $595,000;  David  Nation,  $650,000; and  Patricia  Rice,  $395,000. In
addition to  such severance  compensation,  pursuant to  the change  in  control
agreements,  the unvested  options held  by such  an individual  to purchase CMS
Common Stock (which by virtue  of the Merger will  be converted into options  to
purchase   shares  of  Horizon  Common  Stock)  will  immediately  vest  upon  a
termination of such  individual's employment under  the circumstances  described
above.  As of the Effective Time, the senior executive officers of CMS will have
unvested options to purchase  the following number of  shares of Horizon  Common
Stock: Frank Fritsch, 42,501 shares; Dennis Lehman, 57,438 shares; David Nation,
70,257  shares; and Patricia Rice, 28,586 shares.  The vesting of options upon a
termination of employment following a change in control will be pursuant to  the
change in control agreements; not the original terms of the stock options.

BOARD ARRANGEMENTS

    Pursuant to the Merger Agreement, Horizon will expand its Board of Directors
prior  to  the Effective  Time to  thirteen and  will ensure  that five  of such
directorships will be  filled with individuals  designated by CMS  prior to  the
Effective  Time. CMS intends to designate five of its current directors, Russell
L. Carson, Brian C. Cressey, Rocco A. Ortenzio, Robert A. Ortenzio and LeRoy  S.
Zimmerman, to fill such positions. Pursuant to the Merger Agreement, immediately
after being elected to the Horizon Board of Directors, one of such five nominees
shall  be elected (subject to such nominee's  determination to not serve) to the
Horizon Audit Committee, another  shall be elected  to the Horizon  Compensation
Committee  (provided such designee  shall not be  an employee of  Horizon or any
subsidiary following the Effective Time) and  Rocco A. Ortenzio will be  elected
to the Horizon Executive Committee. The five directors appointed by CMS shall be
nominated  for election as directors  of Horizon at the  first annual meeting of
stockholders of Horizon subsequent to the Effective Time and shall be  nominated
for  election in the  class of directors  whose term expires  at the 1996 annual
meeting of stockholders of Horizon.

    The  Merger   Agreement  provides   that  Horizon   will  maintain   certain
indemnification  and  limitation of  liability provisions  in CMS's  Charter and
By-Laws for a period of six years after the Effective Time and will continue for
six years CMS's directors and  officers liability insurance, subject to  certain
limitations. See "Certain Terms of the Merger Agreement -- Indemnification."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

    The  following  is a  general  summary of  the  material federal  income tax
consequences of the Merger to the holders of CMS Common Stock and is based  upon
current  provisions  of the  Code, existing  regulations thereunder  and current
administrative rulings and court decisions, all of which are subject to  change.
No  attempt has been made  to comment on all  federal income tax consequences of
the Merger that may  be relevant to particular  holders, including holders  that
are subject to special tax rules such as dealers in securities, foreign persons,
mutual  funds, insurance companies,  tax-exempt entities and  holders who do not
hold their shares as capital assets. Holders of CMS Common Stock are advised and
expected to consult  their own  tax advisers  regarding the  federal income  tax
consequences  of the  Merger in  light of  their personal  circumstances and the
consequences under state, local and foreign tax laws.

    No ruling from  the Internal  Revenue Service ("IRS")  has been  or will  be
requested  in connection with the Merger. Horizon has received from its counsel,
Vinson & Elkins L.L.P., an opinion to the effect

                                       49
<PAGE>
that  the  Merger  will  be  treated  for  federal  income  tax  purposes  as  a
reorganization  within the meaning of Section  368(a) of the Code, that Horizon,
Merger Sub and CMS will each be a party to the reorganization within the meaning
of Section 368(b) of  the Code, and  that Horizon, Merger Sub  and CMS will  not
recognize  any gain or loss as a result of  the Merger. It is a condition to the
obligation of Horizon to consummate the Merger that such opinion shall not  have
been  withdrawn or modified in  any material respect. CMS  has received from its
counsel, Drinker Biddle & Reath, an opinion  to the effect that the Merger  will
be  treated  for federal  income  tax purposes  as  a reorganization  within the
meaning of Section 368(a)  of the Code,  that Horizon, Merger  Sub and CMS  will
each  be a party to  the reorganization within the  meaning of Section 368(b) of
the Code, and that stockholders of CMS will not recognize any gain or loss  from
the  receipt of Horizon Common Stock for their CMS Common Stock, other than with
respect to cash received in lieu  of fractional shares of Horizon Common  Stock.
Such   opinions  are  subject  to  certain  assumptions  and  based  on  certain
representations of Horizon, Merger  Sub and CMS. Stockholders  of CMS should  be
aware  that such  opinions are not  binding on the  IRS and no  assurance can be
given that the IRS  will not adopt  a contrary position or  that a contrary  IRS
position would not be sustained by a court.

    Assuming  the Merger qualifies  as a reorganization  under Section 368(a) of
the Code, the following federal income tax consequences will occur:

        (a) no gain or loss will be recognized by Horizon, Merger Sub or CMS  in
    connection with the Merger;

        (b)  no gain or loss will be recognized  by a holder of CMS Common Stock
    upon the exchange of all of such holder's shares of CMS Common Stock  solely
    for shares of Horizon Common Stock in the Merger;

        (c)  the aggregate basis of the  shares of Horizon Common Stock received
    by a CMS stockholder  in the Merger (including  any fractional share  deemed
    received)  will be  the same  as the  aggregate basis  of the  shares of CMS
    Common Stock surrendered in exchange therefor;

        (d) the holding period of the shares of Horizon Common Stock received by
    a CMS  stockholder in  the Merger  will include  the holding  period of  the
    shares  of CMS Common Stock surrendered  in exchange therefor, provided that
    such shares of CMS Common Stock are held as capital assets at the  Effective
    Time; and

        (e) a stockholder of CMS who receives cash in lieu of a fractional share
    will  recognize gain or loss  equal to the difference,  if any, between such
    stockholder's basis in the fractional  share (as described in paragraph  (c)
    above)  and the amount of cash received. Such gain or loss will be a capital
    gain or  loss if  the CMS  Common Stock  is held  by such  stockholder as  a
    capital asset at the Effective Time.

ACCOUNTING TREATMENT

    The  Merger is expected to be accounted for using the "pooling of interests"
method of accounting  pursuant to Opinion  No. 16 of  the Accounting  Principles
Board.  The pooling of interests method of accounting assumes that the combining
companies have  been  merged from  inception,  and the  historical  consolidated
financial  statements  for  periods  prior to  consummation  of  the  Merger are
restated as  though the  companies had  been combined  from inception.  See  the
Unaudited  Pro Forma Condensed Financial  Information and notes thereto included
elsewhere in this Joint Proxy Statement/ Prospectus.

    Horizon  has   been  preliminarily   advised  by   its  independent   public
accountants, Arthur Andersen LLP, that the Merger should be treated as a pooling
of  interests  in  accordance  with  generally  accepted  accounting principles.
Consummation of the Merger is conditioned upon the written confirmation of  such
advice.  Also, such advice  contemplates that each  person who may  be deemed an
affiliate of CMS or  Horizon will enter  into an agreement  with Horizon not  to
sell or otherwise transfer any shares of

                                       50
<PAGE>
CMS  Common Stock or  Horizon Common Stock, as  the case may  be, within 30 days
prior to the Effective Time or any Horizon Common Stock thereafter prior to  the
publication  of financial results  that include at least  30 days of post-Merger
combined operations of Horizon and CMS.

GOVERNMENTAL AND REGULATORY APPROVALS AND MATTERS

    ANTITRUST MATTERS.   Transactions such  as the  Merger are  reviewed by  the
Department  of  Justice  and  the  FTC to  determine  whether  they  comply with
applicable antitrust laws. Under the provisions  of the HSR Act, the Merger  may
not  be consummated until such time as the specified waiting period requirements
of the HSR Act have been satisfied. Horizon and CMS filed notification  reports,
together  with requests  for early termination  of the waiting  period, with the
Department of Justice  and the  FTC under  the HSR Act  on April  20, 1995.  The
applicable  waiting period expired on Saturday, May 20, 1995 with no request for
additional information having been made.

    At any time before or after  the Effective Time, the Department of  Justice,
the FTC or a private person or entity could seek under the antitrust laws, among
other  things, to  enjoin the Merger  or to  cause Horizon to  divest itself, in
whole or in part, of CMS or of other businesses conducted by Horizon. There  can
be no assurance that a challenge to the Merger will not be made or that, if such
a challenge is made, Horizon and CMS will prevail.

   
    STATE  LICENSURE AND CERTIFICATE OF NEED REQUIREMENTS.  Horizon and CMS have
provided the regulatory authorities in all  of the states in which CMS  operates
rehabilitation   hospitals  with   any  required   notices,  disclosures  and/or
applications for  determination of  need  consistent with  applicable  licensure
and/or   certificate   of   need  statutory   and   regulatory   provisions.  In
Massachusetts, CMS filed an application for  determination of need on April  21,
1995.  The application  was accepted as  of May  9, 1995 and  the public comment
period on the application expired on May  11, 1995 with no comments having  been
filed.   On  June  2,  1995,  the   Commonwealth  of  Massachusetts  issued  its
determination of need in respect of the  Merger. At this time, virtually all  of
the  remaining  states  in  which  CMS  operates  rehabilitation  hospitals have
concurred with  Horizon's and  CMS's  view that  the  proposed Merger  does  not
constitute  a change  of ownership for  either licensure or  certificate of need
purposes. At this time,  however, neither Horizon nor  CMS anticipates that  any
such  notification, disclosure or  review will hinder  or delay the transactions
contemplated by the Merger Agreement.
    

    MASSACHUSETTS.   In connection  with Horizon's  acquisition of  Greenery  in
February  1994, the Massachusetts Department of Public Health (the "Department")
deemed Horizon to  be neither suitable  nor responsible in  connection with  its
initial  application to the Department for a  license to acquire and operate the
Massachusetts facilities then operated  by Greenery, due in  part to certain  of
Horizon's  historical  certification  and decertification  experiences  in other
states. Horizon appealed  that determination.  In order to  resolve the  matter,
Horizon entered into an agreement with the Department under which the Department
agreed,  subject to compliance  by Horizon with  the terms of  the agreement, to
issue three  successive  six-month  probationary licenses  to  Horizon  for  the
acquisition  and operation of those facilities and, during the 18-month duration
of the agreement, Horizon agreed to  commit the management of the  Massachusetts
facilities and patient care oversight to a management company owned and operated
by  Horizon's regional  vice president. (During  the pendency  of the agreement,
Horizon derives substantially all of  the financial benefits from the  operation
of  these facilities.) In  addition, Horizon agreed not  to file any application
seeking to  acquire  or manage  any  other  long-term care  or  assisted  living
facility  in Massachusetts for  the duration of the  agreement. Horizon has been
advised by the Department that the agreement does not apply to the  transactions
contemplated  by  the  Merger  Agreement.  Horizon  does  not  believe  that the
agreement with the  Department will  hinder or  delay the  effectiveness of  the
Merger.

    The  first of the probationary licenses contemplated under the agreement was
issued on May 24, 1994  and the second was issued  effective as of November  26,
1994.  Horizon recently filed its  application for renewal probationary licenses
with the Department and anticipates  that those probationary licenses should  be
issued  in June 1995. Horizon believes that its relationship with the Department
has

                                       51
<PAGE>
improved since Horizon began operating in Massachusetts in February 1994.  Thus,
absent  the occurrence of unanticipated  adverse circumstances (which cannot now
be anticipated), Horizon anticipates receiving full licensure at the  expiration
of  the agreement.  Assuming, however, that  the Department  denies Horizon full
licensure and gives Horizon sufficient time to market and sell these facilities,
the denial  of  such  licensure should  not  have  a material  impact  upon  the
financial results of Horizon or the Merger.

    MEDICARE.   The parties to  the Merger Agreement have  been advised by their
counsel that  the transactions  contemplated by  the Merger  Agreement will  not
constitute  a "change of  ownership" of the  Horizon or the  CMS "providers" for
purposes of the Medicare  program, because the  actual "providers" for  Medicare
purposes  are  the  CMS  subsidiaries  in  the  states  in  which  CMS  operates
rehabilitation facilities.

    Except as  described above,  Horizon and  CMS  are not  aware of  any  other
governmental  or regulatory approvals  required for consummation  of the Merger,
other than compliance with applicable securities laws.

    REIMBURSEMENT RATES  FOR CONTRACT  THERAPY  SERVICES.   In April  1995,  the
Health  Care  Financing  Administration  ("HCFA")  issued  a  memorandum  to its
Medicare fiscal intermediaries (the  "Fiscal Intermediaries") as guidelines  for
assessing  costs incurred by inpatient  providers ("Care Providers") relating to
Payment of Occupational and Speech  Language Pathology Services furnished  under
arrangements  including contracts between therapy  providers and Care Providers.
While not binding on  the Fiscal Intermediaries,  the HCFA memorandum  suggested
certain  rates  to the  Fiscal Intermediaries  to assist  them in  making annual
"prudent buyer" assessments  of speech  and occupational therapy  rates paid  by
Care  Providers during the Fiscal Intermediary's  reviews of the Care Providers'
cost reports.  The HCFA  memorandum acknowledges  that the  rates noted  in  the
memorandum  are  not absolute  limits  and should  only  be used  by  the Fiscal
Intermediaries for  comparative purposes.  Following the  issuance of  the  HCFA
memorandum,  meetings between industry  representatives and HCFA  have been held
concerning  the  merits  of  the  HCFA  memorandum.  HCFA  has  asked   industry
associations  and groups to provide  recommendations for inclusion in clarifying
instructions to the Fiscal Intermediaries. In  light of the fluid nature of  the
HCFA  memorandum, neither Horizon nor  CMS can predict what  effect, if any, the
HCFA memorandum will have on Horizon, CMS  or the combined enterprise or if  the
rates  suggested in the HCFA memorandum will continue to be recommended by HCFA.
Additionally, neither Horizon  nor CMS can  determine at this  time whether  the
rates  suggested in  the HCFA memorandum  would be used  by HCFA as  a basis for
developing possible  future  regulations  creating a  salary  equivalency  based
reimbursement  system for speech and occupational therapy services. Although the
managements of Horizon and CMS have developed strategies to deal with  potential
future   changes,  there  can  be  no  assurance  that  future  changes  in  the
administration or interpretation of governmental  health care programs will  not
have  an adverse  effect on  the results  of operations  of Horizon,  CMS or the
combined enterprise.

    HEALTH CARE REFORM  AND BUDGETARY  PROPOSALS.   Various federal  legislators
have  introduced health care  reform and "balanced  budget" proposals, which are
intended to control health  care costs, improve access  to medical services  for
uninsured  individuals and balance the federal  budget by the year 2002. Certain
of these budgetary proposals have been reported out of committee in both  Houses
of Congress. These proposals include reduced rates of growth in the Medicare and
Medicaid programs and proposals to block grant funds to the states to administer
the  Medicaid program.  While these  proposals do not,  at this  time, appear to
affect adversely Horizon, CMS or the combined enterprise, significant changes in
reimbursement levels  under  Medicare  or Medicaid  and  changes  in  applicable
governmental  regulations could affect  the future results  of operations of the
combined enterprise whether positively or negatively. There can be no  assurance
that  future legislation,  health care  or budgetary,  will not  have an adverse
effect on the future results of operation of the combined enterprise.

<PAGE>
CMS DEBT

    The indentures pursuant  to which CMS  has issued  its 10 3/8%  and 10  7/8%
Senior  Subordinated  Notes contain  provisions permitting  each holder  of such
notes, upon a "change in  control" of CMS, to  require that CMS repurchase  such
holder's notes at a purchase price payable in cash in an amount equal to 100% of
the  principal amount thereof, together with  accrued and unpaid interest. As of
March 31, 1995, there  was approximately $264.8  million of Senior  Subordinated
Notes  outstanding  pursuant  to  these indentures.  In  addition,  CMS  will be
required to  repay  amounts  outstanding under  its  existing  revolving  credit
facility,  aggregating approximately  $72 million as  of March 31,  1995, upon a
"change in control." A "change in control" will not occur upon completion of the
Merger for purposes of such indentures  and credit facility because the  holders
of  CMS  Common Stock  immediately prior  to  the Merger  will own,  directly or
indirectly, at  least 40%  of  the outstanding  Horizon  Common Stock  upon  the
completion  of  the Merger.  Horizon  may from  time  to time  make  open market
purchases of Senior Subordinated Notes subsequent to the Effective Time.

RESTRICTIONS ON RESALES BY AFFILIATES

    The shares of  Horizon Common Stock  to be received  by CMS stockholders  in
connection  with the Merger  have been registered under  the Securities Act and,
except as set forth  in this paragraph, may  be traded without restriction.  The
shares  of Horizon Common Stock  to be issued in  connection with the Merger and
received by persons who are deemed to  be "affiliates" (as that term is  defined
in  Rule 144 under the Securities Act) of  CMS prior to the Merger may be resold
by them only  in transactions  permitted by the  resale provisions  of Rule  145
under  the Securities Act (or, in the case of such persons who become affiliates
of Horizon, Rule 144 under the  Securities Act) or as otherwise permitted  under
the  Securities Act. Under  guidelines published by the  Commission, the sale or
other disposition of Horizon Common Stock or CMS Common Stock by an affiliate of
either Horizon or CMS, as the case may be, within 30 days prior to the Effective
Time or the sale or other  disposition of Horizon Common Stock thereafter  prior
to  the  publication of  financial  results that  include  at least  30  days of
post-Merger combined operations of Horizon and CMS (the "Pooling Period")  could
preclude  pooling of interests accounting  treatment of the Merger. Accordingly,
the Merger  Agreement  provides  that each  of  CMS  and Horizon  will  use  all
reasonable efforts to cause its affiliates to execute a written agreement to the
effect  that such persons  will not sell,  transfer or otherwise  dispose of any
shares of CMS Common Stock or Horizon  Common Stock, as the case may be,  during
the  Pooling Period and,  with respect to  affiliates of CMS,  that such persons
will not sell, transfer or otherwise dispose of Horizon Common Stock at any time
in violation of  the Securities  Act or  the rules  and regulations  promulgated
thereunder, including Rule 145.

RIGHTS OF DISSENTING STOCKHOLDERS

    Under  Delaware  law,  neither  Horizon's  nor  CMS's  stockholders  will be
entitled to any appraisal or dissenter's rights in connection with the Merger.

                     CERTAIN TERMS OF THE MERGER AGREEMENT

    The  following description does not purport  to be complete and is qualified
in its  entirety by  reference  to the  Merger Agreement,  a  copy of  which  is
attached  as  Appendix  A  to  this  Joint  Proxy  Statement/Prospectus  and  is
incorporated herein by reference.

EFFECTIVE TIME OF THE MERGER

    The Merger Agreement  provides that,  as promptly as  practicable after  the
satisfaction  or waiver of  the conditions to effecting  the Merger, the parties
shall cause the Merger to be consummated by filing a Certificate of Merger  with
the  Secretary of State of  the State of Delaware, in  such form as required by,
and executed in  accordance with,  the relevant provisions  of the  DGCL. It  is
anticipated that, if the Merger Agreement is approved and adopted at each of the
Horizon  Special Meeting and the CMS Special Meeting and all other conditions to
the Merger have been satisfied or waived,  the Effective Time will occur on  the
date  of  the  Horizon  and  CMS  Special  Meetings  or  as  soon  thereafter as
practicable.

MANNER AND BASIS OF CONVERTING SHARES

   
    At the Effective  Time, each outstanding  share of CMS  Common Stock,  other
than  shares of CMS Common Stock held in the treasury of CMS or owned by Horizon
or any  direct or  indirect wholly-owned  subsidiary of  either Horizon  or  CMS
(which  shares will be  canceled at the  Effective Time) will  be converted into
 .5397 shares of  Horizon Common Stock.  The Merger Agreement  provides that  the
Exchange Ratio is to be calculated by dividing $13.00 by the Horizon Transaction
Value  (as defined  below), rounded to  four decimal  places; PROVIDED, HOWEVER,
that the  Exchange Ratio  shall not  be less  than .4415  nor more  than  .5397.
"Horizon  Transaction  Value"  means  the  average  closing  price  on  the NYSE
Composite Tape of Horizon Common Stock for the 20 NYSE trading days ending  with
the third NYSE trading day immediately preceding the mailing of this Joint Proxy
Statement/Prospectus  to the  stockholders of CMS.  Based on  the foregoing, the
Horizon Transaction  Value  was  equal  to $18.075,  resulting  in  the  maximum
Exchange  Ratio of .5397  shares of Horizon  Common Stock for  each share of CMS
Common Stock. Notwithstanding the foregoing, if  between the date of the  Merger
Agreement  and the Effective Time the outstanding shares of Horizon Common Stock
or CMS Common Stock shall have been changed into a different number of shares or
a  different   class,   by   reason  of   any   stock   dividend,   subdivision,
reclassification,  recapitalization, split,  combination or  exchange of shares,
the Exchange  Ratio  will be  correspondingly  adjusted to  reflect  such  stock
dividend, subdivision, reclassification, recapitalization, split, combination or
exchange of shares.
    

    As  soon as practicable  following the Effective Time,  Horizon will mail to
each record holder of CMS Common Stock immediately prior to the Effective  Time,
a  letter  of transmittal  and  other information  advising  such holder  of the
consummation  of  the  Merger  and  for  use  in  exchanging  CMS  Common  Stock
certificates  for  Horizon  Common  Stock  certificates  and  cash  in  lieu  of
fractional shares. Letters of transmittal  will also be available following  the
Effective  Time at the offices of Horizon  in Albuquerque, New Mexico. After the
Effective Time, there will be no further registration of transfers on the  stock
transfer  books  of CMS  of shares  of  CMS Common  Stock that  were outstanding
immediately prior  to  the Effective  Time.  Share certificates  should  not  be
surrendered  for exchange by stockholders of CMS prior to the Effective Time and
the receipt of a letter of transmittal.

    No fractional shares of Horizon Common  Stock will be issued in the  Merger.
Each stockholder of CMS entitled to a fractional share will receive an amount in
cash equal to the value of such fractional share based upon the closing price of
Horizon  Common Stock on  the NYSE Composite  Tape on the  date of the Effective
Time. No interest  will be paid  on such amount,  and all shares  of CMS  Common
Stock  held by a record holder shall be aggregated for purposes of computing the
amount of such payment.

    Until surrendered and exchanged, each certificate previously evidencing  CMS
Common  Stock  shall represent  solely  Horizon Common  Stock  and the  right to
receive  cash  in  lieu  of  fractional  shares.  Unless  and  until  any   such
certificates  shall  be  so surrendered  and  exchanged, no  dividends  or other

                                       54
<PAGE>
distributions payable to the holders of record of Horizon Common Stock as of any
time after the Effective Time shall be paid to the holders of such  certificates
previously  evidencing CMS Common Stock; PROVIDED,  HOWEVER, that, upon any such
surrender and exchange of such certificates,  there shall be paid to the  record
holders  of  the  certificates issued  and  exchanged therefor  (i)  the amount,
without interest thereon, of dividends and  other distributions, if any, with  a
record date after the Effective Time theretofore paid with respect to such whole
shares  of Horizon Common Stock,  and (ii) at the  appropriate payment date, the
amount of dividends or other distributions, if any, with a record date after the
Effective Time  but  prior to  surrender  and  a payment  date  occurring  after
surrender, payable with respect to such whole shares of Horizon Common Stock.

ASSUMPTION OF OBLIGATIONS TO ISSUE CMS COMMON STOCK

    The  Merger Agreement provides that Horizon and CMS will take such action as
may be necessary to permit  Horizon to assume, at  the Effective Time, each  CMS
Option  that remains unexercised in whole or in part and to substitute shares of
Horizon Common  Stock for  shares of  CMS Common  Stock purchasable  under  such
assumed  CMS Option,  subject to certain  terms and conditions.  The assumed CMS
Option will not give the optionee additional benefits that such optionee did not
have under the CMS Option, and shall be assumed on the same terms and conditions
as the  CMS  Option being  assumed,  subject to  the  matters described  in  the
following paragraph.

    The  number  of shares  of Horizon  Common Stock  purchasable under  any CMS
Option assumed by  Horizon will  be equal  to the  number of  shares of  Horizon
Common  Stock that  the holder  of the CMS  Option would  have received (without
regard to any  vesting schedule) upon  consummation of the  Merger had such  CMS
Option  been exercised in full immediately prior  to the Effective Time, and the
per share exercise price will  be equal to the per  share exercise price of  the
CMS Option divided by the Exchange Ratio.

    Horizon has agreed in the Merger Agreement to assume, at the Effective Time,
the  obligations of CMS with  respect to the issuance  of CMS Common Stock under
the CMS Warrants, the CMS Debenture  and the CMS Earnout Agreements by  agreeing
to  issue in lieu thereof  Horizon Common Stock. Assuming  that no shares of CMS
Common Stock are  issued prior  to the  Effective Time  on exercise  of any  CMS
Options  or the CMS Warrants, on conversion  of the CMS Debenture or pursuant to
the CMS Earnout Agreements, Horizon will be required to reserve for issuance  an
aggregate of 4,394,818 shares of Horizon Common Stock for such purposes.

CONDITIONS TO THE MERGER

    The  respective obligations of Horizon and  CMS to consummate the Merger are
subject to the satisfaction of the following conditions, any or all of which may
be waived in  writing by CMS  and Horizon, in  whole or in  part, to the  extent
permitted  by applicable  law: (a)  the Registration  Statement shall  have been
declared effective by  the Commission under  the Securities Act,  no stop  order
suspending  the  effectiveness of  the  Registration Statement  shall  have been
issued by the  Commission and no  proceedings for that  purpose shall have  been
initiated  by the Commission; (b) the Merger Agreement and the Merger shall have
been approved and adopted by the requisite vote of the stockholders of CMS,  and
the  issuance of the Horizon Common Stock in the Merger shall have been approved
by the requisite vote of the stockholders of Horizon; (c) no Governmental Entity
(as defined in  the Merger  Agreement) or federal  or state  court of  competent
jurisdiction  shall have enacted,  issued, promulgated, enforced  or entered any
statute, rule, regulation,  executive order, decree,  injunction or other  order
(whether  temporary, preliminary or permanent) which  is in effect and which has
the effect of making the Merger illegal or otherwise prohibiting consummation of
the Merger; (d) the applicable waiting period under the HSR Act with respect  to
the transactions contemplated by the Merger Agreement shall have expired or been
terminated;  (e) Horizon and  CMS shall have  been advised in  writing by Arthur

for financial accounting purposes as a  pooling of interests in accordance  with
generally   accepted  accounting  principles  and  the  rules,  regulations  and
interpretations of the Commission and (f)  there shall not be any action  taken,
or  any  statute,  rule,  regulation  or  order  enacted,  entered,  enforced or

                                       55
<PAGE>
deemed applicable to the  Merger by any Governmental  Entity in connection  with
the  grant of a regulatory approval necessary to the continuing operation of the
business or future prospects of CMS,  that imposes any condition or  restriction
upon  Horizon or the  business or operations  of CMS that,  individually or when
taken together with  all such  conditions or restrictions,  would be  materially
adverse to the financial condition, results of operations, business or prospects
of CMS or Horizon.

    The  obligation  of Horizon  to effect  the  Merger is  also subject  to the
satisfaction at or prior to the Effective Time of the following conditions,  any
or  all of which may be  waived in writing by Horizon,  in whole or in part: (a)
each of  the representations  and  warranties of  CMS  contained in  the  Merger
Agreement  and  the Stock  Option Agreement  shall  be true  and correct  in all
material respects as of the  Effective Time as though  made as of the  Effective
Time; (b) CMS shall have performed or complied in all material respects with all
agreements  and covenants  required by the  Merger Agreement to  be performed or
complied with by it on  or prior to the Effective  Time; (c) Horizon shall  have
received all "blue sky" permits and other authorizations necessary to consummate
the  transaction contemplated by the Merger Agreement and (d) none of the events
described in Sections  11(a)(ii) or 13  of CMS's stockholder  rights plan  shall
have  occurred, and the rights thereunder shall not have become unredeemable and
such rights  shall not  become exercisable  for capital  stock of  Horizon  upon
consummation  of the Merger.  Horizon will not waive  the condition described in
clause (c) above.

    The obligation  of  CMS  to  effect  the  Merger  is  also  subject  to  the
satisfaction  at or prior to the Effective Time of the following conditions, any
or all of which may be waived in writing  by CMS, in whole or in part: (a)  each
of the representations and warranties of Horizon and Merger Sub contained in the
Merger  Agreement shall be true  and correct in all  material respects as of the
Effective Time as  though made as  of the  Effective Time; and  (b) Horizon  and
Merger  Sub shall have performed  or complied in all  material respects with all
agreements and covenants  required by the  Merger Agreement to  be performed  or
complied with by them on or prior to the Effective Time.

    There  can be no assurance that all of  the conditions to the Merger will be
satisfied.

pay a  termination fee  to  Horizon under  certain circumstances  and  Horizon's
agreement  to  pay a  termination  fee to  CMS  under certain  circumstances, as
discussed below, in the  event of the termination  of the Merger Agreement,  the

the  parties thereto shall cease, except that no party will be relieved from its
obligations with respect to any breach of the Merger Agreement.

    The Merger Agreement may be amended  by the parties thereto by action  taken
by or on behalf of their respective Boards of Directors at any time prior to the

stockholders of CMS, no amendment  may be made that  would reduce the amount  or
change the type of consideration into which each share of CMS Common Stock shall
be  converted pursuant to the Merger  Agreement upon consummation of the Merger.
At any time prior to the Effective  Time, any party to the Merger Agreement  may
(a)  extend the time for the performance of any of the obligations or other acts
of the other party  thereto, (b) waive any  inaccuracies in the  representations

printing, filing  and mailing  this Joint  Proxy Statement/  Prospectus and  all
Commission  and other  regulatory filing  fees incurred  in connection  with the

transaction  contemplated  by the  Merger Agreement  up to  $5 million),  if the
Merger Agreement  is terminated  in accordance  with its  terms: (a)  by  either
Horizon  or CMS, if the Merger Agreement fails to receive the requisite vote for
approval and adoption  by the stockholders  of CMS at  the CMS Special  Meeting,
and, prior to the time of such meeting, CMS shall have furnished information to,
or  entered into  discussions or  negotiations with,  any person  or entity with
respect to a Competing Transaction involving CMS or any of its subsidiaries  and
the  Board of Directors of  CMS shall not have  reaffirmed its recommendation to
the stockholders of  CMS with respect  to the transactions  contemplated by  the

to do so); (c) by Horizon, if the Board of Directors of CMS shall recommend  any
Competing  Transaction  to CMS's  stockholders (or  resolves to  do so);  (d) by
Horizon, if a tender or exchange offer for  20% or more of the capital stock  of

time of termination a Terminating CMS Breach exists and, with respect to (i) and
(ii) above, within nine months after such termination a Competing Transaction is
consummated or any person shall have acquired beneficial ownership or the  right
to  acquire beneficial ownership of, or any  "group" shall have been formed that
beneficially owns, or has the right  to acquire beneficial ownership of, 20%  or
more  of the then outstanding capital stock of CMS; PROVIDED, HOWEVER, that, for
such purpose only,  a breach of  a representation shall  not be deemed  to be  a
Terminating CMS Breach if the representation was true and correct as of the date
of the Merger Agreement. The "Termination Fee" is equal to $20 million, less the
aggregate amount of any cash

                                       59
<PAGE>
payments to Horizon in excess of $10 million pursuant to provisions of the Stock
Option  Agreement requiring CMS,  under the circumstances  described therein, to
repurchase the Option or the Option Shares (each as defined below).

    The  Merger  Agreement  also  provides  that  Horizon  will  pay  to  CMS  a
termination  fee  of  $10  million  if the  Merger  Agreement  is  terminated in
accordance with its terms: (a) by CMS, if a tender or exchange offer for 20%  or
more  of  the capital  stock of  Horizon  is commenced,  and Horizon's  Board of
Directors does not recommend that stockholders not tender their shares into such
tender offer or exchange  offer; (b) by CMS,  if any person acquires  beneficial
ownership  or the right  to acquire beneficial  ownership of, or  any "group" is
formed that  beneficially  owns,  or  has  the  right  to  acquire  beneficially
ownership  of, 20% or  more of the  then outstanding shares  of capital stock of
Horizon; or (c)(i) by CMS, as a  result of a Terminating Horizon Breach or  (ii)
by Horizon or CMS, if the Merger shall not have been consummated before December
31,  1995 (or  March 31,  1996 if  extended) and  at the  time of  termination a
Terminating Horizon  Breach exists  and, with  respect to  (i) and  (ii)  above,
within  nine months  after such termination  a Horizon  Competing Transaction is
consummated or any person shall have acquired beneficial ownership or the  right
to  acquire beneficial ownership of, or any  "group" shall have been formed that
beneficially owns, or has the right  to acquire beneficial ownership of, 20%  or
more  of the then outstanding capital stock of Horizon; PROVIDED, HOWEVER, that,
for such purpose only, a breach of a representation shall not be deemed to be  a
Terminating  Horizon Breach if the representation was true and correct as of the
date of  the  Merger Agreement.  A  "Horizon Competing  Transaction"  means  any
merger,   consolidation,  share   exchange,  business   combination  or  similar
transaction involving  Horizon or  any of  its Significant  Subsidiaries or  the
acquisition in any manner, directly or indirectly, of a material interest in any
voting  securities of, or a material equity interest in a substantial portion of
the assets of, Horizon or any of its Significant Subsidiaries.

INDEMNIFICATION

    The Merger Agreement  provides that,  for a period  of six  years after  the
Effective  Time,  Horizon  (i)  shall  not  amend  or  otherwise  modify certain
limitation of  liability and  indemnification provisions  of CMS's  Charter  and
By-Laws  in a manner  that would adversely  affect the rights  thereunder of any
individuals who  at any  time prior  to  the Effective  Time were  directors  or
officers  of CMS in  respect of acts or  omissions occurring at  or prior to the
Effective Time (including, without limitation, the transactions contemplated  by
the  Merger Agreement), unless such amendment or modification is required by law
and (ii)  shall  cause  to be  maintained  in  effect the  current  policies  of
directors'  and officers' liability  insurance maintained by  CMS (or substitute
policies under certain circumstances) with respect to claims arising from  facts
or  events which occurred before the  Effective Time; PROVIDED, HOWEVER, that in
no event shall  Horizon be  required to  expend more  than 200%  of the  current
annual premiums paid by CMS for such insurance.

                             STOCK OPTION AGREEMENT

    Pursuant to the Stock Option Agreement, Horizon has an option ("the Option")
to  acquire from CMS up to 5,793,567 shares, subject to certain adjustments (the
"Option Shares"), of CMS Common Stock for  $13.00 per share in cash, subject  to
certain  adjustments  (the  "Exercise  Price").  The  number  of  Option  Shares
represents 15% of the outstanding shares of CMS Common Stock on March 31,  1995,
the  date of  the Stock  Option Agreement. The  Option was  granted by  CMS as a
condition of  and  in  consideration  for Horizon's  entering  into  the  Merger
Agreement.

    The  Option may be exercised by Horizon, in whole or in part, at any time or
from time to time after the Merger Agreement becomes terminable by Horizon under
circumstances that would, if  the Merger Agreement were  terminated as a  result
thereof,  entitle Horizon to the Termination  Fee described under "Certain Terms
of the Merger  Agreement --  Expenses and Termination  Fees." The  circumstances
giving  rise to the  exercisability of the  Option are referred  to in the Stock
Option Agreement as "Trigger Events."

                                       60
<PAGE>
    At any  time  during  which  the  Option  is  exercisable  (the  "Repurchase
Period"),  Horizon  may require  CMS  to purchase  the  Option or  Option Shares
purchased by Horizon  pursuant to  the Option (the  "Put Right")  at the  prices
described  below under  "Option Repurchase  Price" and  "Option Share Repurchase
Price," respectively.

    OPTION REPURCHASE  PRICE.   The repurchase  price for  the Option  would  be
calculated  by reference to the  underlying Option Shares and  would be equal to
the excess, if any,  of (i) the  "Market/Offer Price" for  shares of CMS  Common
Stock  as of the date Horizon exercises  the Put Right (the "Repurchase Exercise
Date") over (ii) the Exercise Price.  The "Market/Offer Price" is the higher  of
(A)  the highest  price per  share offered  as of  the Repurchase  Exercise Date
pursuant to any tender or exchange offer or other Competing Transaction that was
made prior to such date and not terminated or withdrawn as of such date and  (B)
the  Fair Market Value of CMS Stock as  of such date. The "Fair Market Value" of
any share shall be the average of  the daily closing sales price for such  share
on the NYSE during the ten NYSE trading days prior to the fifth NYSE trading day
preceding the date such is to be determined.

    OPTION  SHARE REPURCHASE PRICE.  Under the second alternative, the aggregate
repurchase price per Option Share to be repurchased would be equal to the sum of
(i) the Exercise Price  paid by Horizon for  Option Shares acquired pursuant  to
the  Option  and (ii)  the  difference between  the  Market/Offer Price  and the
Exercise Price, but only if the Market/Offer Price is greater than the  Exercise
Price.

    Horizon  may not exercise its Put Right in a manner that would result in the
cash payment to Horizon of an aggregate amount pursuant to the Put Right of more
than $30  million, less  the amount,  if any,  of the  Termination Fee  paid  to
Horizon pursuant to the Merger Agreement. This limitation, however, relates only
to  the repurchase obligation, and does  not limit Horizon's ability to exercise
the Option in accordance with its terms.

    The Option will terminate upon the earlier of: (i) the Effective Time;  (ii)
the termination of the Merger Agreement in accordance with its terms (other than
upon  or during the continuance of a Trigger Event); or (iii) 180 days following
any termination of  the Merger  Agreement upon or  during the  continuance of  a
Trigger Event (or if, at the expiration of such 180 day period the Option cannot
be  exercised  by  reason of  any  applicable  judgment, decree,  order,  law or
regulation, ten business days after such impediment to exercise shall have  been
removed  or shall have become  final and not subject to  appeal, but in no event
under this  circumstance later  than December  31, 1996).  The Option  may  not,
however,  be exercised if Horizon  is in material breach  of any of its material
representations or warranties, or in material breach of any of its covenants  or
agreements, contained in the Stock Option Agreement or in the Merger Agreement.

    The  obligation of  CMS to  issue Option Shares  to Horizon  pursuant to the
Stock Option  Agreement  is  subject to  certain  conditions,  including,  among
others,  that (i) all waiting periods, if  any, under the HSR Act, applicable to
the issuance of Option  Shares shall have expired  or have been terminated;  and
(ii)  all consents,  approvals, orders  or authorizations  of, or registrations,
declarations or  filings with,  any  Governmental Entity,  if any,  required  in
connection  with the issuance of Option Shares shall have been obtained or made,
as the case may be.

    Horizon has agreed that for the five year period ending March 31, 2000  (the
"Expiration  Date"), it will vote any shares of capital stock of CMS acquired by
Horizon pursuant to  the Option ("Restricted  Shares) or otherwise  beneficially
owned  by Horizon (within the  meaning of Rule 13d-3  under the Exchange Act) on
each matter submitted  to a vote  of stockholders  of CMS for  and against  such
matter  in the same proportion as the vote  of all other stockholders of CMS are
voted (whether by proxy or otherwise)  for and against such matter. Horizon  has
also  agreed  that  prior to  the  Expiration  Date, it  will  not,  directly or
indirectly, by operation of law or otherwise, sell, assign, pledge, or otherwise
dispose of  or transfer  any Restricted  Shares beneficially  owned by  Horizon,
other than (i) pursuant to an exercise of the Put Right described above, (ii) in
connection with a "Qualifying Offer" or (iii) in connection with the exercise of
certain   registration  rights  granted   in  the  Stock   Option  Agreement.  A

                                       61
<PAGE>
"Qualifying Offer"  is a  tender or  exchange offer  that has  been approved  or
recommended,  or otherwise determined to be fair to and in the best interests of
the stockholders  of the  CMS, by  a majority  of the  members of  the Board  of
Directors  of CMS, which majority shall include a majority of directors who were
directors prior to the announcement of such tender or exchange offer.

    The Stock Option Agreement has been filed as an exhibit to the  Registration
Statement  of  which this  Joint Proxy  Statement/Prospectus is  a part,  and is
incorporated herein by reference.

                                VOTING AGREEMENT

    In order to  induce Horizon  to enter into  the Merger  Agreement, Rocco  A.
Ortenzio,  Chairman of the Board  and Chief Executive Officer  of CMS, Robert A.
Ortenzio, President  and Chief  Operating Officer  of CMS  and two  corporations
controlled  by them (collectively,  the "Stockholders") entered  into the Voting
Agreement with Horizon. As of the CMS Record Date, the Stockholders held  shares
of  CMS Common  Stock representing  in the  aggregate approximately  8.9% of the
voting power of CMS.

    Pursuant to the Voting Agreement, the Stockholders have, among other things,
agreed to vote  all shares of  CMS Common  Stock beneficially owned  by them  in
favor of the Merger and (if requested by Horizon, not (i) to attend, or vote any
CMS Common Stock beneficially owned by them at, any annual or special meeting of
stockholders or (ii) to execute any written consent of stockholders) against any
combination  proposal or other matter that may interfere or be inconsistent with
the Merger.

    The Stockholders have also agreed that no Stockholder or any corporation  or
other  person  controlled  by  any Stockholder  or  any  affiliate  or associate
thereof, other than  CMS and  its subsidiaries  (collectively, the  "Stockholder
Group"),  will,  directly or  indirectly,  sell, transfer,  pledge  or otherwise
dispose of, or grant  a proxy with  respect to, any shares  of CMS Common  Stock
beneficially  owned by any member  of the Stockholder Group  to any person other
than Horizon or  its designee, or  grant an option  with respect to  any of  the
foregoing,  or enter into any other agreement or arrangement with respect to any
of the foregoing.

    The Voting Agreement also provides that  no Stockholder or any other  member
of  the Stockholder Group will initiate,  solicit or encourage (including by way
of  furnishing  information  or  assistance),  or  take  any  other  action   to
facilitate, any inquiries or the making of any proposal relating to, or that may
reasonably  be expected  to lead  to, any  Competing Transaction,  or enter into
discussions or  negotiate with  any  person or  entity  in furtherance  of  such
inquiries  or to obtain  a Competing Transaction,  or agree to,  or endorse, any
Competing Transaction, or authorize or permit any of the officers, directors  or
employees  of any  Stockholder or  any member  of the  Stockholder Group  or any
investment  banker,   financial   advisor,   attorney,   accountant   or   other
representative   retained  by  any  Stockholder  or  any  other  member  of  the
Stockholder Group to take any such action.

    The parties to the Voting Agreement  have agreed that nothing in the  Voting
Agreement  will be deemed to prohibit  any Stockholder from acting in accordance
with such  Stockholder's  fiduciary  duties  solely  to  the  extent  that  such
Stockholder  is acting in the capacity of officer or director of CMS. The Voting
Agreement terminates upon the termination of the Merger Agreement.

    The Voting  Agreement has  been  filed as  an  exhibit to  the  Registration
Statement  of  which this  Joint Proxy  Statement/Prospectus is  a part,  and is
incorporated herein by reference.

                      INTRODUCTION TO UNAUDITED PRO FORMA
                         CONDENSED FINANCIAL STATEMENTS

    The  unaudited pro forma condensed balance  sheet at February 28, 1995 gives
effect to (i) the  combination of Horizon's  historical assets, liabilities  and
stockholders'   equity  at  February  28,   1995  with  the  historical  assets,
liabilities and stockholders' equity of CMS  as of March 31, 1995 accounted  for
as  a pooling of interests  as if the Merger had  occurred on February 28, 1995,
and  (ii)  as  adjusted  to  give  effect  to  the  individually   insignificant
acquisitions effected subsequent to February 28, 1995 as if the transactions had
occurred  on February 28, 1995. Such adjustments are more fully described in the
notes to the unaudited pro forma condensed balance sheet.

    The unaudited pro forma condensed statement  of earnings for the year  ended
May  31, 1994  gives effect  to (i)  the Merger  accounted for  as a  pooling of
interests, (ii) the merger  of Greenery into Horizon,  (iii) the acquisition  of
peopleCARE  and (iv) individually insignificant acquisitions effected subsequent
to June 1, 1993 by Horizon, as if all such transactions had occurred on June  1,
1993. The unaudited pro forma condensed statement of earnings for the year ended
May  31,  1994 includes  historical results  of operations  as follows:  (i) the
results of operations of Horizon  for its fiscal year  ended May 31, 1994,  (ii)
the  results of operations of CMS for its fiscal year ended June 30, 1994, (iii)

months  ended  April  30,  1994  and  (v)  the  results  of  operations  of  the
individually insignificant acquisitions for varying fiscal periods to the extent
not  already  included  in  the  historical  amounts  of  Horizon.  The combined
historical amounts have been  adjusted by giving effect  to the assumptions  and
adjustments  included  in  the accompanying  notes  to the  unaudited  pro forma
condensed financial statements.

    The unaudited pro forma condensed statement of earnings for the nine  months
ended  February  28, 1995  gives effect  to (i)  the Merger  accounted for  as a
pooling of  interests,  (ii) the  acquisitions  of peopleCARE  and  individually
insignificant  acquisitions by Horizon, as if all such transactions had occurred
on June 1, 1994. The unaudited pro forma condensed statement of earnings for the
nine months ended February 28, 1995 includes historical results of operations as
follows: (i) the  results of  operations of Horizon  for the  nine months  ended
February  28, 1995, (ii)  the results of  operations of CMS  for the nine months
ended March 31, 1995, (iii) the results  of peopleCARE for the two months  ended
July   31,  1994  and  (iv)  the  results  of  operations  of  the  individually
insignificant acquisitions for varying interim periods to the extent not already
included in the historical amounts  of Horizon. The combined historical  amounts
have  been adjusted by giving effect to the assumptions and adjustments included
in the  accompanying  notes  to  the unaudited  pro  forma  condensed  financial
statements.

    The unaudited pro forma condensed statements of earnings for the years ended
May  31, 1993 and 1992 give  effect to the Merger accounted  for as a pooling of
interests as  if  the  transaction  had  occurred on  June  1,  1992  and  1991,
respectively.  The unaudited pro forma condensed  statements of earnings for the
years ended May 31, 1993 and  1992 include the historical results of  operations
as  follows: (i) the results of operations of Horizon for its fiscal years ended
May 31, 1993 and 1992 and (ii) the  results of operations of CMS for its  fiscal
years ended June 30, 1993 and 1992.

    The  following pro forma  financial information may  not necessarily reflect
the financial condition or results of  operations of Horizon or Horizon and  CMS
combined,  which would have  actually resulted had  the transactions referred to
above occurred as  of the  date and  for the  periods indicated  or reflect  the
future  earnings of Horizon or Horizon and CMS combined. The pro forma financial
information should be  read in conjunction  with the accompanying  notes to  the
unaudited  pro forma condensed financial statements and the financial statements

                         CONDENSED FINANCIAL STATEMENTS
                                 (IN THOUSANDS)

I.  (1) The Merger Agreement provides  that each share of CMS Common Stock  will
    be converted into .5397 shares of Horizon Common Stock.

    (2) Other income, principally interest and merger expenses of CMS which have
    been  reported separately on CMS'  historical statements of operations, have
    been reclassified to operating revenues  and cost of services,  respectively
    for  purposes  of  presentation in  the  unaudited pro  forma  statements of
    earnings.

    (3) Notes receivable from officers at February 28, 1995 relating to the sale
    of 2,362  shares  of  CMS Common  Stock  has  been separately  stated  as  a
    component of stockholders' equity in CMS's historical amounts.

    (4)  The  pro forma  combined  earnings per  share  amounts for  all periods
    presented are based on the  weighted average shares outstanding for  Horizon
    plus  CMS  weighted average  shares outstanding  multiplied by  the Exchange
    Ratio.

    (5) The pro forma after acquisitions earnings per share amounts for the nine
    months ended  February 28,  1995 and  the year  ended May  31, 1994  reflect
    additional  weighted  average  shares  of  1,047  and  3,020,  respectively,
    relating to  the  issuance  of  Horizon  Common  Stock  in  connection  with
    individually insignificant acquisitions.

II. EXPLANATION OF PRO FORMA ADJUSTMENTS:

                            PRO FORMA BALANCE SHEETS

(1)  ISSUANCE OF SHARES AND MERGER COSTS

    (a)  To record the  issuance of 20,845  shares of Horizon  Common Stock, par
value $.001 per share, upon conversion of the 38,624 shares of CMS Common Stock,
par value $.01 per share, outstanding at March 31, 1995.

    (b) Certain non-recurring adjustments estimated to approximate $23,000  will
be   recorded  in  connection   with  the  Merger.   These  adjustments  include
approximately  $14,900  for  the   settlement  of  obligations  under   existing
employment  agreements  with  the chief  executive  officer of  CMS  as follows:
$11,000 related  to  the settlement  of  existing future  bonus  rights;  $3,700
related  to termination payments  payable following a change  in control of CMS;
and $200 related to the amortization  of a non-compete agreement. The  remaining
approximate  $8,100 represents expenses  related to effecting  the Merger. These
costs have been accrued in the unaudited pro forma combined balance sheet as  of
February  28, 1995. All of these costs are expected to be charged against income
of the  combined  company immediately  upon  closing  of the  Merger,  which  is
currently  expected  to  be in  Horizon's  first  quarter of  fiscal  year 1996.
Accordingly, the effects of these costs have not been reflected in the unaudited
pro forma condensed statements of earnings.  The impact of these adjustments  on
earnings  from continuing operations for the nine months ended February 28, 1995
is expected to  be $13,915, net  of income taxes.  Including these  adjustments,
earnings  from continuing operations per share-primary and fully diluted for the
nine months  ended February  28,  1995 would  have been  $0.22  on a  pro  forma
combined after acquisitions basis.

(2)  HISTORICAL ACQUISITIONS

    The  unaudited  pro  forma  condensed balance  sheet  at  February  28, 1995
includes the historical aggregated balance sheets of insignificant  acquisitions
by Horizon subsequent to February 28, 1995.

                                       72
<PAGE>
(3)  HISTORICAL INSIGNIFICANT ACQUISITIONS ADJUSTMENTS

    (a) Adjustments for $10,056 and $2,716 have been recorded to land, buildings
and  equipment and goodwill,  respectively, in the  Horizon and combined balance
sheets as of February 28, 1995 to  record the value of assets purchased and  the
excess  purchase  price related  to  the insignificant  acquisitions  by Horizon
completed after February 28, 1995. In addition, adjustments of $(9), $13,984 and
$(1,203) have  been recorded  to common  stock, additional  paid-in capital  and
retained  earnings, respectively, to eliminate the acquired entities' equity and
record the issuance of 761,719 shares of Horizon Common Stock, respectively.

                        PRO FORMA STATEMENTS OF EARNINGS

(4)  POOLING OF INTERESTS ADJUSTMENTS

    (a) Adjustments  have been  recorded to  conform CMS's  financial  statement
presentation  to  that  of Horizon.  Amounts  reclassified  represent historical
administrative and general expense which has  been classified by CMS as cost  of
services expense.

(5)  The unaudited pro forma condensed statement of earnings for the nine months
ended  February  28,  1995  includes the  historical  results  of  operations of
peopleCARE prior  to  its  acquisition on  July  29,  1994 and  the  results  of
operations  of  individually  insignificant  acquisitions  by  Horizon  for  the
appropriate periods prior to each individual acquisition.

    The unaudited pro forma condensed statement  of earnings for the year  ended
May  31, 1994 includes the historical results of operations of Greenery prior to
its acquisition on February  10, 1994, the historical  results of operations  of
peopleCARE  for  the twelve  months  ended April  30,  1994 and  the  results of
operations of individually insignificant acquisitions by Horizon for appropriate
twelve month periods.

(6)  ACQUISITION ADJUSTMENTS:

GREENERY ACQUISITION ADJUSTMENTS

    Horizon completed the Greenery merger  and related transactions on  February
10,  1994. As a result,  the historical financial statements  of Horizon for the
year ended  May 31,  1994 include  approximately three  and one-half  months  of
Greenery  operations. Following are adjustments  recorded to reflect the effects
of the Greenery merger  and related transactions for  the approximate eight  and
one-half  month period  ended February  10, 1994 as  if the  Greenery merger had
occurred on June 1, 1993:

    (a)   In  connection  with  the Greenery  merger,  Horizon  purchased  three
facilities  previously  leased  by Health  and  Rehabilitation  Properties Trust
("HRP") to Greenery  and incurred  additional debt related  to a  Greenery-owned
facility to raise additional cash. In addition, certain assets for which a write
down  of  approximately $3,100  was recorded  by Greenery  during the  eight and
one-half months  ended  February 10,  1994  were  sold, along  with  two  office
buildings  owned and operated by Greenery. Greenery also recorded a $775 loss on
the sale of one facility to HRP and expenses of $2,006 related to severance  pay
and  other Greenery merger  costs in preparation for  the Greenery merger during
the eight and one-half months ended February 10, 1994. The impact of the  above,
as well as the additional

                                       73
<PAGE>
depreciation  and  amortization expense  for the  allocation of  excess purchase
price to buildings and equipment  and goodwill (assuming a 40-year  amortization
period for goodwill), on earnings before income taxes is as follows:

    PEOPLECARE ACQUISITION ADJUSTMENT

    Horizon completed the peopleCARE acquisition on July 29, 1994. As a  result,
the  historical  financial  statements  of Horizon  for  the  nine  months ended
February 28, 1995 include approximately  seven months of peopleCARE  operations.
Following  are adjustments  recorded to  reflect the  effects of  the peopleCARE
acquisition and related transactions for the  twelve month period ended May  31,
1994  and two month period ended July  29, 1994 as if the peopleCARE acquisition
had occurred on June 1, 1993 and June 1, 1994, respectively. The adjustments for
the peopleCARE acquisition consist of the following:

    (g)  The historical financial  information reported for peopleCARE  includes
certain  de minimis  amounts which  were not acquired  or assumed  by Horizon in
connection with this acquisition. Therefore,  adjustments have been recorded  to
eliminate  interest and other  operating revenues of  $200 and $33  for the year
ended May 31, 1994  and the nine months  ended February 28, 1995,  respectively,
and cost of services expense of $211 and $35 for the year ended May 31, 1994 and
the  nine  months ended  February 28,  1995,  respectively, associated  with the
predecessor entity operations which were not acquired by Horizon.

    (h)    Adjustments  of  $300  and  $50  have  been  recorded  to   eliminate
distributions  to peopleCARE's prior owners for the  year ended May 31, 1994 and
the nine months ended February 28, 1995, respectively.

    (i)   The peopleCARE  acquisition  purchase price  included the  payment  of
$55,616  in cash, which was  funded from Horizon's line  of credit, for title to
seven facilities.  This acquisition  also called  for Horizon  to enter  into  a
capital  lease for  six facilities  formerly owned  by peopleCARE.  As a result,
interest expense has been adjusted  as follows for the  year ended May 31,  1994
and the nine months ended February 28, 1995, respectively:

    INDIVIDUALLY INSIGNIFICANT ACQUISITIONS AND ACQUISITIONS ADJUSTMENTS

    Horizon has completed various individually insignificant transactions in the
period from June 1, 1994 to March 1, 1995. As a result, the historical financial
statements  of  Horizon for  the  nine months  ended  February 28,  1995 include
varying periods of operations related  to these acquisitions. The following  are
adjustments  recorded to reflect the results of operations of these acquisitions
to the extent not included in Horizon's historical results of operations for the
periods ended February 28,  1995 and May  31, 1994 as  if such acquisitions  had
occurred on June 1, 1994 and June 1, 1993, respectively. The adjustments for the
insignificant acquisitions consist of the following:

    (k)    Adjustments for  ($821) and  ($921) have  been recorded  to eliminate
historical lease expense for the purchase of  leases for the year ended May  31,
1994 and the nine months ended February 28, 1995, respectively.

    (l)    Adjustments  for $2,483  and  $1,424  have been  recorded  to reflect
interest expense on long-term  debt incurred to fund  acquisitions for the  year
ended May 31, 1994 and the nine months ended February 28, 1995, respectively.

    (m)   Adjustments for $1,105 and $682 have been recorded to depreciation and
amortization to  reflect  the additional  costs  associated with  the  purchased
entities  for the year ended May 31, 1994 and the nine months ended February 28,
1995, respectively.

(7)  INCOME TAXES:

    An effective tax rate of 39.5% has  been applied to all entities and to  all
periods  except with respect  to historical CMS for  which the actual historical
effective tax rate has been maintained.

(8)  GREENERY:

    Administrative and  general  expenses included  in  the original  pro  forma
condensed  consolidated  financial  statements  prepared  to  reflect  Horizon's
acquisition of Greenery have been amended to reflect certain adjustments to  the
Greenery  historical period from  October 1, 1993  through the acquisition date,
February 11, 1994. The pro forma  financial statements were first amended  eight
months  following  the acquisition  to properly  reflect as  a reduction  to net
income in the unaudited pre-acquisition period adjustments that Horizon made  to
predecessor  company reserves that had not  previously been reflected in income.
The reduction  to  income  associated with  these  adjustments  totaled  $7,777,
pre-tax,  and $4,705  net of tax.  Further adjustments were  recorded related to
errors  discovered  in  the  original  Greenery  purchase  accounting  and   the
resolution   of  a   pre-acquisition  contingency  totaling   $7,710  and  $471,
respectively, pre-tax, and $4,665 and $285, respectively, net of taxes. All such
adjustments have been properly reflected in  each of the accompanying pro  forma
condensed statements of earnings for the year ended May 31, 1994.

                      DESCRIPTION OF HORIZON CAPITAL STOCK

GENERAL

    The following  descriptions of  certain  of the  provisions of  the  Horizon
Charter  and the Horizon Bylaws are necessarily general and do not purport to be
complete and are qualified in their entirety by reference to the Horizon Charter
and the  Horizon Bylaws,  which are  included as  exhibits to  the  Registration
Statement of which this Joint Proxy Statement/Prospectus is a part.

HORIZON COMMON STOCK

    Horizon  is authorized to issue 150,000,000  shares of Horizon Common Stock,
par value $.001. As of the Horizon Record Date, there were 29,469,296 shares  of
Horizon  Common Stock issued and outstanding  and approximately 1,450 holders of
record of Horizon Common Stock. The holders of Horizon Common Stock are entitled
to one vote for each share on  all matters submitted to a vote of  stockholders.
The  holders of Horizon Common Stock do not have cumulative voting rights in the
election of  directors  of  Horizon  unless  and until  a  person  or  group  of
affiliated  or  associated  persons  has acquired  beneficial  ownership  in one
transaction or a series of related transactions  of 40% or more of the stock  of
any  class or series thereof  entitled to vote in  the election of directors, in
which case cumulative voting will be in effect commencing with the first  annual
election  of directors  subsequent to such  acquisition. The  holders of Horizon
Common Stock are entitled to receive ratably  such dividends, if any, as may  be
declared  by the Horizon Board  of Directors out of  legally available funds. In
the event of liquidation, dissolution or  winding up of Horizon, the holders  of
Horizon  Common Stock  are entitled  to share ratably  in all  assets of Horizon
remaining after provision  for payment  of liabilities and  satisfaction of  the
liquidation  preference of  any shares  of Horizon  Preferred Stock  (as defined
below) that may  be outstanding.  The holders of  Horizon Common  Stock have  no
preemptive,  subscription,  redemptive  or  conversion  rights.  The outstanding
shares are fully paid and nonassessable. The rights, preferences and  privileges
of  holders of Horizon  Common Stock may  become subject to  those of holders of
Horizon Preferred Stock, if Horizon should issue Horizon Preferred Stock in  the
future. See "Horizon Preferred Stock."

RIGHTS TO PURCHASE PREFERRED STOCK

    On September 12, 1994, the Board of Directors of Horizon declared a dividend
of  one preferred share purchase right (a "Right") for each outstanding share of
Horizon Common  Stock held  of record  on September  22, 1994  and approved  the
further  issuance of Rights with  respect to all shares  of Horizon Common Stock
that are  subsequently issued.  Each  Right entitles  the registered  holder  to
purchase from Horizon one-thousandth of a share of Series A Junior Participating
Preferred  Stock, par value $.001 per  share ("Series A Preferred"), of Horizon,
at a price of $110 per one-thousandth of a share (the "Purchase Price"), subject
to adjustment. See "Horizon Preferred Stock -- Series A

                                       78
<PAGE>
Preferred." Until the occurrence of  certain events described below, the  Rights
are  not exercisable, will  be evidenced by the  certificates for Horizon Common
Stock and will not be transferable apart from the Horizon Common Stock.

    DETACHMENT OF RIGHTS; EXERCISE.   Initially, the Rights  will attach to  all
certificates  representing  outstanding shares  of Horizon  Common Stock  and no
separate Right Certificates will be  distributed. The Rights will separate  from
the  Horizon Common Stock and a Distribution Date will occur upon the earlier of
(i) 10 business days following a public  announcement that a person or group  of
affiliated or associated persons (an "Acquiring Person") has acquired beneficial
ownership  of 20% or  more of the  outstanding Voting Shares  (as defined in the
Rights  Agreement)  of  Horizon,  or   (ii)  10  business  days  following   the
commencement  or  announcement of  an intention  to commence  a tender  offer or
exchange offer  the  consummation  of  which  would  result  in  the  beneficial
ownership by a person or group of 20% or more of such outstanding Voting Shares.

    The  Rights  are not  exercisable until  the Distribution  Date. As  soon as
practicable following the  Distribution Date,  separate certificates  evidencing
the  Rights (the "Right  Certificates") will be  mailed to holders  of record of
Horizon Common Stock as of  the close of business  on the Distribution Date  and
such separate Right Certificates alone will thereafter evidence the Rights.

    If  a person or  group were to acquire  20% or more of  the Voting Shares of
Horizon, each Right then  outstanding (other than  Rights beneficially owned  by
the  Acquiring Person which would become null  and void) would become a right to
buy  that  number  of  shares  of   Horizon  Common  Stock  (or  under   certain
circumstances,  the equivalent number of one-thousandths  of a share of Series A
Preferred) that at the time of such acquisition would have a market value of two
times the Purchase Price of the Right.

    If  Horizon  were  acquired  in  a  merger  or  other  business  combination
transaction  or more than 50%  of its consolidated assets  or earning power were
sold, proper  provision  will be  made  so that  each  holder of  a  Right  will
thereafter  have the  right to  receive, upon the  exercise thereof  at the then
current Purchase Price of the  Right, that number of  shares of common stock  of
the  acquiring company which at the time of such transaction would have a market
value of two times the Purchase Price of the Right.

    ANTIDILUTION AND  OTHER ADJUSTMENTS.   The  number of  shares (or  fractions
thereof)  of Series  A Preferred or  other securities or  property issuable upon
exercise of the Rights, and the Purchase Price payable, are subject to customary
adjustments from time  to time to  prevent dilution. The  number of  outstanding
Rights  and the number  of shares (or  fractions thereof) of  Series A Preferred
issuable upon exercise of each Right are also subject to adjustment in the event
of a stock split of the Horizon Common Stock or a stock dividend on the  Horizon
Common  Stock payable in Horizon Common Stock or subdivisions, consolidations or
combinations of the Horizon Common Stock  occurring, in any such case, prior  to
the Distribution Date.

    EXCHANGE  OPTION.  At any time after the acquisition by a person or group of
affiliated or associated persons of beneficial  ownership of 20% or more of  the
outstanding  Voting Shares of Horizon and before  the acquisition by a person or
group of 50% or more  of the outstanding Voting  Shares of Horizon, the  Horizon
Board  of Directors may, at its option,  issue Horizon Common Stock in mandatory
redemption of, and  in exchange for,  all or  part of the  then outstanding  and
exercisable  Rights (other than Rights owned by such person or group which would
become null and void) at an exchange ratio of one share of Horizon Common  Stock
(or  one-thousandth of  a share of  Series A  Preferred) for each  two shares of
Horizon Common  Stock for  which  each Right  is  then exercisable,  subject  to
adjustment.

    REDEMPTION  OF RIGHTS.  At  any time prior to  the first public announcement
that a person or  group has become the  beneficial owner of 20%  or more of  the
outstanding Voting Shares, the Horizon Board of Directors may redeem all but not
less  than all  the then outstanding  Rights at a  price of $.01  per Right (the
"Redemption Price"). The redemption of the Rights may be made effective at  such
time, on

                                       79
<PAGE>
such  basis and with  such conditions as  the Horizon Board  of Directors in its
sole discretion may establish. Immediately upon the action of the Horizon  Board
of Directors ordering redemption of the Rights, the right to exercise the Rights
will  terminate and the only  right of the holders of  Rights will be to receive
the Redemption Price.

    EXPIRATION; AMENDMENT OF RIGHTS.   The Rights will  expire on September  22,
2004,  unless earlier  redeemed or  exchanged. The  terms of  the Rights  may be
amended by the Horizon Board of Directors without the consent of the holders  of
the  Rights, including an amendment to extend the expiration date of the Rights,
and, provided a Distribution Date has not occurred, to extend the period  during
which   the  Rights  may  be  redeemed,  except  that  after  the  first  public
announcement that a person or  group has become the  beneficial owner of 20%  or
more  of the  outstanding Voting  Shares, no  such amendment  may materially and
adversely affect the interests of the holders of the Rights.

    The Rights  have  certain  anti-takeover  effects.  The  rights  will  cause
substantial  dilution  to a  person or  group that  attempts to  acquire Horizon
without the approval of the Horizon  Board of Directors. The Rights should  not,
however,  interfere  with  any  merger or  other  business  combination  that is
approved by the Horizon Board of Directors.

    The description and terms of the Rights are set forth in a Rights  Agreement
(the  "Horizon Rights Agreement") dated as of September 15, 1994 between Horizon
and Chemical  Trust  Company  of  California, as  Rights  Agent.  The  foregoing
description  of the Rights does  not purport to be  complete and is qualified in
its entirety by reference to the Rights Agreement, a copy of which is  available
free of charge from Horizon.

HORIZON PREFERRED STOCK

    GENERAL.   Horizon is authorized to issue 500,000 shares of Preferred Stock,
par value $.001 per share ("Horizon  Preferred Stock"), of which 150,000  shares
had been designated as Series A Preferred as of September 12, 1994. No shares of
Horizon  Preferred Stock  were outstanding  at September  12, 1994.  The Horizon
Board of Directors has authority, without stockholder approval, to issue  shares
of  Horizon Preferred Stock in one or more series and to determine the number of
shares,  designations,  dividend  rights,   conversion  rights,  voting   power,
redemption  rights, liquidation preferences and other  terms of any such series.
The  issuance  of  Preferred  Stock,  while  providing  desired  flexibility  in
connection  with  possible  acquisitions  and  other  corporate  purposes, could
adversely affect the  voting power of  holders of Horizon  Common Stock and  the
likelihood  that such holders  will receive dividend  payments and payments upon
liquidation and could  have the effect  of delaying, deferring  or preventing  a
change  in control of Horizon. Horizon has  no present plans for any issuance of
Horizon Preferred Stock, other  than the reserved shares  of Series A  Preferred
Stock issuable pursuant to the Rights.

    SERIES  A PREFERRED.   The terms of  the Series A  Preferred are designed so
that the value of each one-thousandth of a share purchasable upon exercise of  a
Right  will approximate  the value  of one  share of  Horizon Common  Stock. The
Series A Preferred is non-redeemable and will rank junior to all other series of
Horizon's Preferred Stock. Each whole share of Series A Preferred is entitled to
receive a quarterly preferential  dividend in an amount  per share equal to  the
greater of (i) $1.00 in cash, or (ii) in the aggregate, 1,000 times the dividend
declared  on the Horizon Common Stock. In  the event of liquidation, the holders
of the Series  A Preferred are  entitled to receive  a preferential  liquidation
payment  equal to the greater of (i) $1,000 per share, or (ii) in the aggregate,
1,000 times the payment made  on the Horizon Common Stock.  In the event of  any
merger,  consolidation or other transaction in which the Horizon Common Stock is
exchanged for or changed into other stock or securities, cash or other property,
each whole share of Series  A Preferred is entitled  to receive 1,000 times  the
amount  received per share of Horizon Common Stock. Each whole share of Series A
Preferred is entitled to 1,000 votes on  all matters submitted to a vote of  the
stockholders  of Horizon, and Series A Preferred will generally vote together as
one class with  the Horizon  Common Stock  and any  other capital  stock on  all
matters submitted to a vote of stockholders of Horizon.

CERTAIN PROVISIONS OF HORIZON CHARTER AND BYLAWS

    Horizon's  Charter provides for  a classified Board  of Directors with three
classes, each  class  to consist  as  nearly as  possible  of one-third  of  the
directors. Currently, the authorized number of directors on the Horizon Board of
Directors is eight. Each director serves for a term of three years and until his
or her successor is elected and qualified. A classified Board of Directors could
make  it more difficult for stockholders,  including those holding a majority of
the outstanding shares,  to force an  immediate change in  the composition of  a
majority of the Horizon Board of Directors. Staggered terms moderate the pace of
changes in the Horizon Board of Directors by extending the minimum time required
to elect a majority of directors from one to two years.

    Directors  may be  removed only  for cause  by the  affirmative vote  of the
holders of two-thirds of outstanding shares entitled to vote, provided that  any
director  elected by  holders of any  series of Horizon  Preferred Stock, voting
separately as a class, may be removed only for cause by the affirmative vote  of
the  holders of two-thirds  of the outstanding  shares of such  series. For this
purpose "cause  for removal"  means  an adjudication  by  a court  of  competent
jurisdiction  that the director  to be removed  (i) is liable  for negligence or
misconduct in the performance of his duty,  (ii) has been convicted of a  felony
or  (iii) has acted or failed  to act in a manner  which is in derogation of the
director's duties.

    The Horizon Charter provides that, except in the case of nominations by  the
Horizon  Board of Directors, written notice must be given of any nomination of a
director, (i) with respect  to an election  to be held at  an annual meeting  of
stockholders,  not  later than  ten days  prior to  the date  which is  one year
following the date of the  notice of the prior  year's annual meeting, and  (ii)
with respect to an election to be held at a special meeting of stockholders, not
later  than the close of business on the seventh day following the day of notice
of such meeting.

    Certain actions  taken by  the  Horizon Board  of Directors,  including  the
appointment and removal of officers of Horizon, designation of committees of the
Horizon  Board  of  Directors  and  appointment  of  members  of  any  committee
established by the Horizon Board of  Directors, require the affirmative vote  of
80%  of  the  then authorized  number  of  directors. The  Horizon  Charter also
provides that the number of directors  on the Horizon Board of Directors  cannot
be  increased or decreased  without the approval  of 80% of  the then authorized
number of directors. Newly created directorships resulting from any increase  in
the authorized number of directors and any vacant directorships may be filled by
the affirmative vote of at least 80% of the directors then in office.

    The  Horizon Charter provides  that special meetings  of stockholders may be
called by the Horizon Board of Directors or by the holders of not less than  25%
of the outstanding shares of any class or any series thereof entitled to vote on
the  election of  directors. Holders  of any  series of  Horizon Preferred Stock
entitled to elect or remove one or  more directors separately as a class may  do
so  at  special meetings,  which may  be called  only for  such purposes  by the
holders of 25%  of the  outstanding shares of  such series.  The Horizon  Bylaws
provide  that  at special  meetings of  stockholders only  such business  may be
conducted as is  (i) specified in  the written notice  of meeting, (ii)  brought
before  the meeting at the direction of  the Horizon Board of Directors or (iii)
specified in a written notice given by or on behalf of the stockholders not more
than ten days after the date of the official notice of the meeting. The  Horizon
Charter  also provides that all stockholder actions must be taken at stockholder
meetings and not by written consent in lieu of a meeting.

    The provisions of  the Horizon  Charter described  above may  be amended  or
repealed  only by  the vote  of holders  of two-thirds  of Horizon's outstanding
shares of all  classes or series  thereof entitled  to vote on  the election  of
directors.  The  Horizon Bylaws  may  be adopted,  amended  or rescinded  by the
Horizon Board  of Directors  or by  the vote  of holders  of two-thirds  of  the
outstanding shares of all classes or series of capital stock entitled to vote on
the election of directors.

                                       81
<PAGE>
STOCKHOLDER VOTE REQUIRED TO APPROVE CERTAIN BUSINESS COMBINATIONS

    The  Horizon Charter requires the approval by holders of at least two-thirds
of the outstanding shares of all classes or series of capital stock entitled  to
vote  on the  election of  directors for (i)(a)  any merger  or consolidation of
Horizon or  any  subsidiary  of Horizon  with  or  into, (b)  any  sale,  lease,
exchange,  mortgage, pledge,  transfer or  other disposition  of any substantial
part (defined generally  as 30%  or more  of the  total assets  of the  relevant
entity  or leasehold  interests in  more than ten  facilities) of  the assets of
Horizon or any subsidiary of Horizon to or with, or (c) the issuance or transfer
of securities of  Horizon or  any subsidiary  in exchange  for cash,  securities
(other  than securities  of Horizon  which by  their terms  are convertible into
other securities of Horizon) or other property to, a Related Person (as  defined
below),  (ii) any reclassification of securities or recapitalization of Horizon,
merger  or  consolidation  of  Horizon  with  any  subsidiary  or  any   similar
transaction  which has the effect of  increasing the proportionate interest of a
Related Person or any person associated or affiliated with a Related Person,  or
(iii) the adoption of a plan of liquidation or dissolution of Horizon.

    "Related  Person"  is defined  as  any person  (other  than a  subsidiary of
Horizon, certain employee  benefit plans  and Continuing  Directors (as  defined
below))  that,  together  with  such  person's  affiliates  and  associates, (i)
directly or indirectly, beneficially own or have the right to acquire or to vote
more than 5% of the Voting Shares  (as defined in the Horizon Charter); or  (ii)
within the preceding two years beneficially owned or had the right to acquire or
to vote not less than 5% of the Voting Shares; or (iii) is an assignee of or has
otherwise  succeeded, within the  preceding two years, to  any shares of capital
stock of Horizon  beneficially owned  by any  Related Person,  in a  transaction
other than a public offering within the meaning of the Securities Act.

    Notwithstanding  the foregoing, such stockholder approval is not required if
the transaction  is  approved by  at  least  80% of  all  Continuing  Directors.
"Continuing  Directors"  are  directors of  Horizon  who either  (i)  were first
elected prior to the date as of which any Related Person that proposes to  enter
into  or become a party to a business combination or other transaction described
above became a beneficial  owner of more  than 5% of the  Voting Shares or  (ii)
were  designated as Continuing Directors (prior  to being elected as a director)
by a majority of the then Continuing Directors; provided that all members of the
Horizon Board of Directors on  July 27, 1994, and  all persons nominated by  the
Horizon  Board  of  Directors  as  directors  of  Horizon  and  elected  by  the
stockholders  at  the  1994  Annual  Meeting  of  Stockholders  are   Continuing
Directors.

    The  Horizon  Charter allows  the  Continuing Directors,  in  evaluating any
business combination or other transaction listed above, to consider, in addition
to the  adequacy  of  the  amount  to  be  paid  in  connection  with  any  such
transaction,  certain  specified factors  and any  other factors  the Continuing
Directors deem relevant. Among the factors the Continuing Directors may consider
are: (i) the  social and  economic effects of  the transaction  on Horizon,  its
employees,  patients and  other elements of  the communities  in which Horizon's
facilities are located; (ii) the  business and financial condition and  earnings
prospects  of the  other party  or parties  to such  transaction; and  (iii) the
competence, experience  and integrity  of the  other party  or parties  to  such
transaction and its or their management.

    The  provisions described above  may tend to  deter any potential unfriendly
offers or other efforts to  obtain control of Horizon  that are not approved  by
the  Horizon  Board  of  Directors  and  thereby  deprive  the  stockholders  of
opportunities to sell shares  at above-market prices.  Such provisions may  also
have  the  effect of  preventing changes  in  the management  of Horizon.  It is
possible that  such  provisions  could  make it  more  difficult  to  accomplish
transactions that stockholders may otherwise deem to be in their best interests.

    The   foregoing  provisions  of  the   Horizon  Charter  regarding  business
combinations and other similar transactions may  be amended or repealed only  by
the vote of holders of two-thirds of Horizon's outstanding shares of all classes
or series of capital stock entitled to vote on the election of Directors.

TRANSFER AGENT AND REGISTRAR

    The  transfer agent and  registrar for the Horizon  Common Stock is Chemical
Mellon Shareholder Services.

               COMPARATIVE RIGHTS OF HORIZON AND CMS STOCKHOLDERS

    If  the  Merger  is  consummated,  the  stockholders  of  CMS  will   become
stockholders  of Horizon. The rights of the stockholders of both Horizon and CMS
are governed by and subject to the provisions of the DGCL. The rights of current
CMS stockholders following the  Merger will be governed  by the Horizon  Charter
and  Horizon's Bylaws rather than the provisions of the CMS Charter and By-Laws.
The following is a  brief summary of certain  differences between the rights  of
Horizon stockholders and the rights of CMS stockholders, and is qualified in its
entirety  by  reference to  the  relevant provisions  of  the DGCL,  the Horizon
Charter and Bylaws and the CMS Charter and By-Laws.

NUMBER, CLASSIFICATION AND REMOVAL OF DIRECTORS

    The Horizon Charter and Bylaws provide  for the classification of the  Board
of  Directors of  Horizon into three  classes, with  directors serving staggered
three-year terms. The Horizon Charter also provides that the number of directors
shall be five unless otherwise determined  by 80% of the then authorized  number
of  directors. The foregoing  provisions cannot be  altered, amended or repealed
without the affirmative  vote of the  holders of not  less than 66  2/3% of  the
Voting  Shares  (as defined  in the  Horizon Charter).  Currently the  number of
Horizon directors  is eight,  but will  be increased  upon consummation  of  the
Merger. See "The Merger -- Board Arrangements."

    The  CMS Charter and By-Laws provide for  the classification of the Board of
Directors of CMS. CMS's  By-Laws provide that the  number of directors shall  be
fixed  from time to time by the CMS Board, but may not consist of less than five
nor more than 13 persons. Currently, the number of CMS directors is seven.

    The Horizon Charter allows directors to  be removed only for cause and  such
removal  must be approved by 66 2/3% of the outstanding shares of Horizon Common
Stock entitled to  vote for the  election of directors.  The CMS Charter  allows
directors  to be removed only for cause and such removal must be approved by 75%
of the outstanding shares of capital stock entitled to vote for the election  of
directors.

VOTING RIGHTS

    Neither  Horizon's nor CMS's  Charter provides for  cumulative voting rights
under  current  circumstances,  although  Horizon's  Charter  does  provide  for
cumulative  voting rights if any stockholder attains ownership of 40% or more of
the shares of stock of any class or series entitled to vote for the election  of
directors.

POWER TO CALL SPECIAL MEETINGS

    Horizon's  Charter provides  that a special  meeting of  stockholders may be
called by a majority of directors then in  office or by the holders of not  less
than  25% of the issued  and outstanding shares of stock  of any class or series
entitled to vote for the election of  directors. In addition, if the holders  of
any  preferred stock  of Horizon  are entitled  to elect  one or  more directors
separately as  a  class,  the  holders  of 25%  of  such  preferred  stock  then
outstanding  may  call a  special meeting  for  limited purposes.  CMS's By-Laws
provide that a special meeting of  stockholders may be called by the  President,
by  a majority of CMS's Directors  or by the holders of  a majority of the stock
entitled to vote at the meeting.

STOCKHOLDER VOTE REQUIRED FOR CERTAIN TRANSACTIONS

    The Horizon Charter contains certain  provisions that require that a  higher
percentage   of  stockholders  approve  mergers,   consolidations,  sales  of  a
substantial amount of assets and other similar transactions involving a  Related
Person  (or an Affiliate or Associate  thereof) than would otherwise be required
under the  DGCL, subject  to  certain exceptions.  See "Description  of  Horizon
Capital Stock." The CMS Charter does not contain a similar provision.

ACTION BY WRITTEN CONSENT

    Horizon's Charter does not permit action to be taken by stockholders without
a  meeting. Because the  CMS Charter does  not contain a  similar provision, the
DGCL permits the taking of stockholder action by written consent.

    Horizon's Bylaws may be amended by the  Board of Directors of Horizon or  by
the  holders of not  less than 66  2/3% of the  Voting Shares outstanding. CMS's
By-Laws may be amended by the Board of Directors of CMS and by the holders of  a
majority  of the outstanding shares  of stock present and  entitled to vote at a

    SECTION 1.05.    DIRECTORS  AND  OFFICERS.   The  directors  of  Merger  Sub
immediately  prior to the Effective Time shall be the directors of the Surviving
Corporation,  each  to  hold  office  in  accordance  with  the  Certificate  of
Incorporation  and Bylaws of the Surviving  Corporation, and the officers of the
Company immediately prior  to the Effective  Time shall be  the officers of  the

                                   ARTICLE II
               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

    SECTION  2.01.    MERGER  CONSIDERATION;  CONVERSION  AND  CANCELLATION   OF
SECURITIES.   At  the Effective Time,  by virtue  of the Merger  and without any
action on the part of the Acquiror Companies, the Company or the holders of  any
of the Company's securities:

        (a)  Subject to the other  provisions of this Article  II, each share of
    common stock, par  value $.01  per share,  of the  Company ("Company  Common
    Stock")  issued  and outstanding  immediately  prior to  the  Effective Time
    (excluding any Company  Common Stock  described in Section  2.01(c) of  this
    Agreement)  shall be converted into a number  of shares of common stock, par
    value $.001 per share ("Acquiror Common Stock") of Acquiror equal to  $13.00
    divided  by the "Acquiror Transaction Value" as hereinafter defined, rounded
    to four  decimal  places  (the "Common  Stock  Exchange  Ratio");  provided,
    however, that notwithstanding the foregoing, the Common Stock Exchange Ratio
    shall  not  be less  than  .4415 nor  more  than .5397.  The  term "Acquiror
    Transaction Value" shall  mean the  average closing  price on  the New  York
    Stock  Exchange Composite Tape of Acquiror Common  Stock for the 20 New York
    Stock Exchange trading days  ending with the third  New York Stock  Exchange
    trading  day immediately preceding the date  of mailing of the Company Proxy
    Statement (as defined below). Notwithstanding the foregoing, if between  the
    date  of this  Agreement and  the Effective  Time the  outstanding shares of
    Acquiror Common Stock or Company Common Stock shall have been changed into a
    different number of  shares or  a different class,  by reason  of any  stock
    dividend,    subdivision,    reclassification,    recapitalization,   split,
    combination or exchange of shares, the Common Stock Exchange Ratio shall  be
    correspondingly  adjusted  to  reflect  such  stock  dividend,  subdivision,
    reclassification,  recapitalization,  split,  combination  or  exchange   of
    shares.

        (b)  As a result of their conversion pursuant to subsection 2.01(a), all
    shares of  Company Common  Stock shall  cease to  be outstanding  and  shall
    automatically  be canceled and retired, and each certificate ("Certificate")
    previously evidencing Company Common Stock outstanding immediately prior  to
    the  Effective Time  (other than Company  Common Stock  described in Section
    2.01(c) of this Agreement) ("Converted Shares") shall thereafter  represent,
    subject  to  Section 2.02(e)  of this  Agreement, that  number of  shares of
    Acquiror Common Stock determined pursuant to the Common Stock Exchange Ratio
    and, if applicable, the right to receive cash pursuant to Section 2.02(e) of
    this Agreement  (the "Merger  Consideration"). The  holders of  Certificates
    previously  evidencing Converted Shares shall cease  to have any rights with
    respect to such Converted Shares except  as otherwise provided herein or  by
    law.  Such  Certificates  previously evidencing  Converted  Shares  shall be
    exchanged for certificates evidencing whole shares of Acquiror Common  Stock
    upon the surrender of such Certificates in accordance with the provisions of
    Section  2.02 of  this Agreement.  No fractional  shares of  Acquiror Common
    Stock shall be issued  and, in lieu  thereof, a cash  payment shall be  made
    pursuant  to Section 2.02(e) of this Agreement. From and after the Effective
    Time, former stockholders of record of the Company shall be entitled to vote
    at any  meeting of  holders of  Acquiror Common  Stock the  number of  whole
    shares  of  Acquiror  Common Stock  into  which their  Converted  Shares are
    converted,  regardless  of  whether   such  holders  have  exchanged   their
    certificates representing the Converted Shares for certificates representing
    Acquiror  Common Stock in accordance with  the provisions of this Agreement.
    Until surrendered for exchange in accordance with the provisions of  Section
    2.02 of this

                                      A-2
<PAGE>
    Agreement, each Certificate theretofore representing Converted Shares (other
    than  shares  of Company  Common Stock  to be  canceled pursuant  to Section
    2.01(c) of this Agreement) shall from and after the Effective Time represent
    for all purposes only  shares of Acquiror Common  Stock and/or the right  to
    receive cash, as set forth in this Agreement.

        (c)  Notwithstanding any  provision of  this Agreement  to the contrary,
    each share of Company Common Stock held  in the treasury of the Company  and
    each  share  of Company  Common Stock  owned  by Acquiror  or any  direct or
    indirect wholly owned subsidiary of  Acquiror or of the Company  immediately
    prior  to the Effective Time shall  be canceled and extinguished without any
    conversion thereof and no payment shall be made with respect thereto.

        (d) Each share of common stock, par value $.001 per share, of Merger Sub
    issued and  outstanding immediately  prior to  the Effective  Time shall  be
    converted  into 210,000 shares of common stock, par value $.01 per share, of
    the Surviving Corporation.

    SECTION  2.02.      PAYMENT  FOR   COMPANY   COMMON  STOCK;   SURRENDER   OF
CERTIFICATES.
        (a)  EXCHANGE FUND.   Promptly after the  Effective Time, Acquiror shall
    deposit, or cause  to be deposited,  with a bank  or trust company  mutually
    agreeable  to the parties to this  Agreement (the "Exchange Agent"), for the
    benefit  of  the  former  holders  of  Converted  Shares,  for  exchange  in
    accordance   with  this  Article   II,  through  the   Exchange  Agent,  (i)
    certificates evidencing a number of shares of Acquiror Common Stock equal to
    the product of the Common Stock  Exchange Ratio multiplied by the number  of
    Converted  Shares and (ii) cash  in an amount equal  to the aggregate amount
    required to be paid in lieu of fractional interests of Acquiror Common Stock
    pursuant to Section 2.02(e). Subject to the provisions of subsection (f)  of
    this  Section 2.02, Acquiror shall, if and  when a payment date has occurred
    with respect to a dividend or distribution that has been declared subsequent
    to the Effective Time, deposit with the Exchange Agent an amount in cash (or
    property of like  kind to  that which  is the  subject to  such dividend  or
    distribution)  equal to the  dividend or distribution  per share of Acquiror
    Common Stock times the number of  shares of Acquiror Common Stock  evidenced
    by  Certificates that have not theretofore  been surrendered for exchange in
    accordance with this Section 2.02. The certificates and cash (and  property,
    if any) deposited with the Exchange Agent in accordance with this subsection
    2.02(a)  are hereinafter  referred to as  the "Exchange  Fund". The Exchange
    Agent shall, pursuant to  irrevocable instructions, deliver Acquiror  Common
    Stock  (and any dividends  or distribution related  thereto) and/or cash, as
    described above, in  exchange for surrendered  Certificates pursuant to  the
    terms  of this Agreement out of the Exchange Fund. Except as contemplated by
    Section 2.02(e) of this Agreement, the  Exchange Fund shall not be used  for
    any other purpose.

        (b)  LETTER OF TRANSMITTAL.  As  soon as practicable after the Effective
    Time, Acquiror  will send  to each  record holder  of Company  Stock at  the
    Effective  Time a letter of transmittal  and other appropriate materials for
    use in surrendering Certificates to the Exchange Agent.

        (c) PAYMENT PROCEDURES.  Promptly after the Effective Time, the Exchange
    Agent shall  distribute to  each  former holder  of Converted  Shares,  upon
    surrender   to  the  Exchange   Agent  of  one   or  more  Certificates  for
    cancellation, together with a duly executed and properly completed letter of
    transmittal, the  Merger Consideration  for  each Converted  Share  formerly
    represented  thereby, in accordance  with the provisions  of Section 2.01 of
    this Agreement. 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,  with  signatures  guaranteed,  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 such  person  shall
    establish  to the satisfaction of Acquiror that such tax has been paid or is
    not applicable. Notwithstanding  the foregoing, neither  the Exchange  Agent
    nor  any party  hereto shall  be liable  to any  former holder  of Converted
    Shares for any cash, Acquiror Common Stock or dividends thereon delivered to
    a public official pursuant to applicable  escheat law. No interest shall  be
    paid  on any  Merger Consideration  payable to  former holders  of Converted
    Shares.

        (d) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES OF ACQUIROR  COMMON
    STOCK.    No dividends  or other  distributions declared  or made  after the
    Effective Time with  respect to  Acquiror Common  Stock with  a record  date
    after  the Effective Time shall  be paid to the  holder of any unsurrendered
    Certificate with respect to  the shares of  Acquiror Common Stock  evidenced

                                      A-3
<PAGE>
    thereby  and no Merger Consideration shall be paid to any such holder, until
    the holder  of such  Certificate shall  surrender such  Certificate. If  any
    holder  of  Converted  Shares shall  be  unable to  surrender  such holder's
    Certificates because such  Certificates have  been lost  or destroyed,  such
    holder  may deliver in lieu thereof an  affidavit and indemnity bond in form
    and substance and with surety  reasonably satisfactory to Acquiror.  Subject
    to applicable laws, following surrender of any such Certificate, there shall
    be  paid  to  the holder  of  the  certificates evidencing  whole  shares of
    Acquiror Common Stock  issued in  exchange therefor,  without interest,  (i)
    promptly,  the amount of any cash payable with respect to a fractional share
    of Acquiror  Common Stock  to  which such  holder  is entitled  pursuant  to
    Section  2.02(e)  of this  Agreement and  the amount  of dividends  or other
    distributions with a record date  after the Effective Time theretofore  paid
    with  respect to such whole shares of Acquiror Common Stock, and (ii) at the
    appropriate payment date,  the amount of  dividends or other  distributions,
    with  a record date  after the Effective  Time but prior  to surrender and a
    payment date occurring after surrender,  payable with respect to such  whole
    shares of Acquiror Common Stock.

        (e) NO FRACTIONAL SHARES.
           (i)  Notwithstanding anything herein to the contrary, no certificates
       or scrip evidencing fractional shares  of Acquiror Common Stock shall  be
       issued  upon  the  surrender  for  exchange  of  Certificates,  and  such
       fractional share interests will not entitle the owner thereof to vote  or
       to  any  rights  as  a  stockholder of  Acquiror.  In  lieu  of  any such
       fractional shares,  each holder  of  Company Stock  upon surrender  of  a
       Certificate  for exchange  pursuant to this  Article II shall  be paid an
       amount  in  cash  (without  interest),  rounded  to  the  nearest   cent,
       determined by multiplying (a) the per share closing price on the New York
       Stock  Exchange  ("NYSE") of  Acquiror Common  Stock on  the date  of the
       Effective Time (or, if  shares of Acquiror Common  Stock do not trade  on
       the NYSE on such date, the first date of trading of Acquiror Common Stock
       on  the NYSE after the Effective Time)  by (b) the fractional interest of
       Acquiror Common Stock to  which such holder  would otherwise be  entitled
       (after  taking into account  all Converted Shares held  of record by such
       holder at  the Effective  Time),  subject to  the provisions  of  Section
       2.02(c) of this Agreement.

           (ii)  As soon as practicable after the determination of the amount of
       cash, if  any, to  be paid  to former  holders of  Converted Shares  with
       respect  to any fractional share interests  of Acquiror Common Stock, the
       Exchange Agent shall promptly pay such amounts to such former holders  of
       Converted  Shares subject  to and  in accordance  with the  terms of this
       Section 2.02. Acquiror will make available to the Exchange Agent the cash
       necessary for this purpose.

        (f) TERMINATION OF EXCHANGE FUND.  Any portion of the Exchange Fund that
    remains unclaimed by the former holders  of Converted Shares for six  months
    after  the Effective Time  shall be delivered to  Acquiror, upon demand, and
    any former holders  of Converted  Shares who have  not theretofore  complied
    with  this Article II shall thereafter look  only to Acquiror for the Merger
    Consideration and dividends  or distributions  to which  they are  entitled,
    without any interest thereon.

        (g)  WITHHOLDING.  Acquiror (or any affiliate thereof) shall be entitled
    to deduct and withhold from the consideration otherwise payable pursuant  to
    this  Agreement to  any former  holder of  Converted Shares  such amounts as
    Acquiror (or any affiliate thereof) is required to deduct and withhold  with
    respect to the making of such payment under the Code, or any other provision
    of  federal, state, local or foreign tax law. To the extent that amounts are
    so withheld by  Acquiror, such  withheld amounts  shall be  treated for  all
    purposes  of this Agreement as having been  paid to the former holder of the
    Converted Shares in respect of which such deduction and withholding was made
    by Acquiror.

        (h) EFFECT OF  ESCHEAT LAWS.   None Acquiror  nor the  Company shall  be
    liable to any holder of shares of Company Stock for any Merger Consideration
    (or  dividends or distributions with respect thereto) or cash delivered to a
    public official pursuant  to any  applicable abandoned  property escheat  or
    similar law.

                                      A-4
<PAGE>
    SECTION  2.03.   STOCK TRANSFER  BOOKS.   At the  Effective Time,  the stock
transfer books of  the Company shall  be closed  and there shall  be no  further
registration  of transfers of shares of  Company Stock thereafter on the records
of the Company.

                                  ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

    The Company hereby represents and warrants to the Acquiror Companies that:

    SECTION 3.01.  ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.  The Company is
a corporation,  and each  of  the Company's  subsidiaries  is a  corporation  or
partnership,  duly organized,  validly existing and  in good  standing under the
laws of the jurisdiction of its incorporation or organization, has all requisite
power and authority to own, lease and operate its properties and to carry on its
business as it is now being conducted and is duly qualified and in good standing
to do  business  in  each jurisdiction  in  which  the nature  of  the  business
conducted  by  it or  the  ownership or  leasing  of its  properties  makes such
qualification necessary, other than  where the failure to  be so duly  qualified
and in good standing could not reasonably be expected to have a Company Material
Adverse  Effect.  The term  "Company Material  Adverse Effect"  as used  in this
Agreement shall  mean any  change or  effect that,  individually or  when  taken
together  with all other such changes or effects, would be materially adverse to
the financial condition,  results of  operations, business or  prospects of  the
Company  and its subsidiaries, taken  as a whole, at the  time of such change or
effect. Section 3.01 of the Disclosure Schedule delivered by the Company to  the
Acquiror  Companies  concurrently  with  the execution  of  this  Agreement (the
"Company Disclosure Schedule") sets forth, as  of the date of this Agreement,  a
true  and  complete  list of  all  the  Company's directly  or  indirectly owned
subsidiaries,  together   with  (A)   the  jurisdiction   of  incorporation   or
organization  of  each  subsidiary  and  the  percentage  of  each  subsidiary's
outstanding capital stock  or other  equity interests  owned by  the Company  or
another  subsidiary of the  Company and (B)  an indication of  whether each such
subsidiary is a "Significant Subsidiary" as  defined in Section 9.03(f) of  this
Agreement.  Except  as  set forth  in  Section  3.01 of  the  Company Disclosure
Schedule, neither  the  Company nor  any  of  its subsidiaries  owns  an  equity
interest  in  any partnership  or joint  venture  arrangement or  other business
entity that  is material  to  the financial  condition, results  of  operations,
business or prospects of the Company and its subsidiaries, taken as a whole.

    SECTION  3.02.   CERTIFICATE OF INCORPORATION  AND BYLAWS.   The Company has
heretofore furnished or made available  to Acquiror complete and correct  copies
of   the  Certificate  of  Incorporation  and   the  Bylaws  or  the  equivalent
organizational documents,  in each  case  as amended  or  restated to  the  date
hereof, of the Company and each of its subsidiaries. Neither the Company nor any
of  its corporate subsidiaries is  in violation of any  of the provisions of its
Certificate of Incorporation or Bylaws (or equivalent organizational documents).
Except as disclosed in  the Company Disclosure Schedule,  none of the Company  s
noncorporate   subsidiaries   is  in   violation  of   any  provisions   of  its
organizational documents  (the  "Constituent  Documents") other  than  any  such
violations  that could  not reasonably  be expected  to have  a Company Material
Adverse Effect.

    SECTION 3.03.  CAPITALIZATION.

        (a) The authorized capital stock  of the Company consists of  80,000,000
    shares of Company Common Stock and 10,000,000 shares of preferred stock, par
    value  $.01 per  share ("Company Preferred  Stock"), of  which 50,000 shares
    have been designated as  Series A Junior  Participating Preferred Stock  and

    described in this subsection (a). Since March 28, 1995, the Company has  not
    granted  any options for, or other rights to purchase, any shares of capital
    stock of the  Company. Each of  the issued  shares of capital  stock of,  or
    other  equity interests in, each of the Company and its subsidiaries is duly
    authorized, validly issued  and, in  the case  of shares  of capital  stock,
    fully  paid and nonassessable, and has not  been issued in violation of (nor

    any of its subsidiaries is a party or is bound, and, except as set forth  in
    Section  3.21  of the  Company Disclosure  Schedule  and in  the Constituent
    Documents, all such  issued shares or  other equity interests  owned by  the
    Company  or a  subsidiary of  the Company  are owned  free and  clear of all
    security interests, liens, claims,  pledges, agreements, limitations on  the
    Company's or such subsidiaries' voting rights, charges or other encumbrances
    of any nature whatsoever.

        (b)  Except as set forth in Section 3.03(a) above, no bonds, debentures,
    notes or other  indebtedness of  the Company having  the right  to vote  (or
    convertible  into or exercisable for securities having the right to vote) on
    any matters on  which stockholders  may vote  ("Voting Debt")  is issued  or
    outstanding. All shares of Company Common Stock which may be issued pursuant
    to  the Option Plans will,  when issued in accordance  with the terms of the
    related Option Plan  and Stock  Option, be  validly issued,  fully paid  and
    nonassessable and not subject to preemptive rights.

    or  otherwise) pursuant to which any person is or may be entitled to receive
    any payment based on the revenues  or earnings, or calculated in  accordance
    therewith, of the Company or any of its subsidiaries. Except as set forth in
    the  Constituent Documents,  there are  no voting  trusts, proxies  or other
    agreements or understandings to which the Company or any of its subsidiaries
    is a party or by which the Company or any of its subsidiaries is bound  with
    respect  to  the voting  of  any shares  of  capital stock  or  other equity
    interests of the Company or any of its subsidiaries.

        (d) The Company has delivered to Acquiror complete and correct copies of
    the Option  Plans and  all forms  of Stock  Options issued  pursuant to  the

    as of March 28, 1995, (i) the number of Stock Options outstanding, (ii)  the
    exercise  price of  each outstanding  Stock Option  and (iii)  the number of
    Stock Options exercisable.

    SECTION 3.04.  AUTHORITY.  The Company has all requisite corporate power and
authority to execute and deliver this  Agreement and the Stock Option  Agreement
(the  "Transaction Documents"), to perform its obligations under the Transaction
Documents and to  consummate the  transactions contemplated  by the  Transaction
Documents  (subject to, with respect to the Merger, the approval and adoption of
this Agreement by the stockholders of the  Company as set forth in Section  3.16
of  this Agreement). The execution and  delivery of the Transaction Documents by
the Company and the consummation by the Company of the transactions contemplated
by the  Transaction  Documents  have  been  duly  authorized  by  all  necessary
corporate  action and no other corporate proceedings  on the part of the Company
are necessary  to  authorize the  Transaction  Documents or  to  consummate  the
transactions contemplated by the Transaction Documents (subject to, with respect
to  the Merger, the approval and adoption  of this Agreement by the stockholders
of the Company as set forth in Section 3.16 of this Agreement). The  Transaction
Documents have been duly executed and delivered by the Company and, assuming the
due  authorization, execution and delivery thereof by the Acquiror Companies (to
the extent a party thereto), constitute the legal, valid and binding  obligation
of the Company.

    SECTION 3.05.  NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

        (a)  Assuming that all consents,  licenses, permits, waivers, approvals,
    authorizations,  orders,  filings  and  notifications  contemplated  by  the
    exceptions  to Section 3.05(b) are obtained or made, and except as disclosed
    in Section 3.05(a)  of the  Company Disclosure Schedule,  the execution  and
    delivery  of  the Transaction  Documents by  the Company  does not,  and the
    consummation of the transactions contemplated by the Transaction  Documents,
    will  not (i) conflict  with or violate the  Certificate of Incorporation or
    Bylaws, or the equivalent organizational documents, in each case as  amended
    or  restated, of the Company or any  of its subsidiaries, (ii) conflict with
    or violate any  federal, state,  foreign or local  law, statute,  ordinance,
    rule,   regulation,  order,   judgment  or   decree  (collectively,  "Laws")
    applicable to the Company or any of  its subsidiaries or by or to which  any
    of  their respective properties is  bound or subject or  (iii) result in any
    breach of or constitute a default (or an event that with notice or lapse  of
    time or both would become a default)

                                      A-7

    under,  or give to others any rights of termination, amendment, acceleration
    or cancellation of, or require payment under, or result in the creation of a
    lien or encumbrance on any of the properties or assets of the Company or any
    of its  subsidiaries  pursuant  to, any  note,  bond,  mortgage,  indenture,
    contract,  agreement, lease, license, permit,  franchise or other instrument
    or obligation to which the Company or any of its subsidiaries is a party  or
    by  or to  which the  Company or  any of  its subsidiaries  or any  of their
    respective properties is bound  or subject, except  for any such  conflicts,
    violations,  breaches, defaults,  events, rights  of termination, amendment,
    acceleration or cancellation, payment  obligations or liens or  encumbrances
    that  could not  reasonably be expected  to have a  Company Material Adverse
    Effect. The  Board  of  Directors  of the  Company  has  taken  all  actions
    necessary   under  Delaware   Law,  including   approving  the  transactions
    contemplated by the Transaction Documents,  to ensure that the  prohibitions
    on  business combinations set forth  in Section 203 of  Delaware Law do not,
    and will  not, apply  to the  transactions contemplated  by the  Transaction
    Documents  or that certain Voting Agreement (the Voting Agreement ) dated as
    of March  31, 1995  by and  between  Acquiror and  the stockholders  of  the
    Company named therein.

        (b)  The  execution and  delivery of  the  Transaction Documents  by the
    Company do not,  and the  performance of  the Transaction  Documents by  the
    Company  will  not,  require the  Company  to obtain  any  consent, license,
    permit, waiver, approval, authorization or order  of, or to make any  filing
    with  or notification to, any governmental or regulatory authority, federal,
    state, local or foreign (collectively, "Governmental Entities"), except  (i)
    for  applicable  requirements, if  any, of  the Securities  Act of  1933, as
    amended (the "Securities Act"), and the Securities Exchange Act of 1934,  as
    amended  (the "Exchange Act"), state securities  or blue sky laws ("Blue Sky
    Laws"), the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
    (the "HSR  Act"),  and the  filing  and recordation  of  appropriate  merger
    documents as required by Delaware Law, (ii) where the failure to obtain such
    consents,  licenses, permits, waivers,  approvals, authorizations or orders,
    or to make such filings or notifications could not reasonably be expected to
    prevent the Company  from performing its  obligations under the  Transaction
    Documents  and could not  reasonably be expected to  have a Company Material
    Adverse Effect and  (iii) as  disclosed in  Section 3.05(b)  of the  Company
    Disclosure Schedule.

    SECTION 3.06.  PERMITS; COMPLIANCE.

        (a)  Except as  disclosed in Section  3.06(a) of  the Company Disclosure
    Schedule, each of the Company and  its subsidiaries is in possession of  (i)
    all   franchises,  grants,  authorizations,  licenses,  permits,  easements,
    variances,   exemptions,   consents,   certificates,   identification    and
    registration  numbers,  approvals and  orders  necessary to  own,  lease and
    operate its properties  and to  carry on  its business  as it  is now  being
    conducted and (ii) agreements from all federal, state and local governmental
    agencies  and accrediting  and certifying  organizations having jurisdiction
    over such facility or facilities that  are required to operate the  facility
    or  facilities in the manner in which  it or they are currently operated and
    receive reimbursement  for  care  provided to  patients  covered  under  the
    federal   Medicare  program   or  any  applicable   state  Medicaid  program
    (collectively, the "Company Permits"), except  where the failure to  possess
    such  Company Permits  could not  reasonably be  expected to  have a Company
    Material Adverse Effect. Without limiting  the generality of the  foregoing,
    all of the Company's hospitals are certified for participation or enrollment
    in the Medicare program, have a current and valid provider contract with the
    Medicare  program and are  in substantial compliance  with the conditions of
    participation  of  such  programs.  Neither  the  Company  nor  any  of  its
    subsidiaries  has  received  notice  from  the  regulatory  authorities that
    enforce the  statutory or  regulatory provisions  in respect  of either  the
    Medicare or the Medicaid program of any pending or threatened investigations
    or  surveys, and no  such investigations or  surveys are pending  or, to the
    knowledge of the Company,  threatened or imminent  that could reasonably  be
    expected  to have a Company Material  Adverse Effect. Section 3.06(a) of the
    Company Disclosure Schedule sets  forth, as of the  date of this  Agreement,
    all  actions,  proceedings, investigations  or  surveys pending  or,  to the
    knowledge of  the Company,  threatened against  the Company  or any  of  its
    subsidiaries  that could reasonably be expected to result in (i) the loss or

                                      A-8
<PAGE>
    revocation of a Company Permit necessary  to operate one or more  facilities
    or  for a facility  to receive reimbursement under  the Medicare or Medicaid
    programs, (ii) the suspension  or cancellation of  any other Company  Permit
    except  any such Company Permit where  such suspension or cancellation could
    not reasonably be expected to have a Company Material Adverse Effect. Except
    as set forth in Section 3.06(a) of the Company Disclosure Schedule,  neither
    the  Company nor any of its subsidiaries  is in conflict with, or in default
    or violation  of  (a) any  Law  applicable to  the  Company or  any  of  its
    subsidiaries  or by or to which any  of their respective properties is bound
    or subject or (b) any of the Company Permits, except for any such conflicts,
    defaults or  violations that  could not  reasonably be  expected to  have  a
    Company  Material Adverse Effect. Except as  set forth in Section 3.06(a) of
    the Company Disclosure Schedule,  since June 30,  1993, neither the  Company
    nor  any of its  subsidiaries has received from  any Governmental Entity any
    written  notification  with  respect  to  possible  conflicts,  defaults  or
    violations  of  Laws,  except  for  written  notices  relating  to  possible
    conflicts, defaults or violations that  could not reasonably be expected  to
    have a Company Material Adverse Effect.

        (b)  The  Company and  its  subsidiaries, as  appropriate,  are approved
    participating providers in and under  all third party payment programs  from
    which  they receive revenues.  No action or investigation  is pending, or to
    the  best  of  its  knowledge,  threatened  to  suspend,  limit,  terminate,
    condition, or revoke the status of the Company or any of its subsidiaries as
    a  provider in  any such  program, and  neither the  Company nor  any of its
    subsidiaries has  been provided  notice  by any  third  party payor  of  its
    intention  to suspend, limit, terminate, revoke,  condition or fail to renew
    in whole or in  part or decrease the  amounts payable under any  arrangement
    with   the  Company  or  such  subsidiary   as  a  provider,  which  action,
    investigation or proceeding would have a Company Material Adverse Effect.

        (c) The Company and  its subsidiaries have filed  on a timely basis  all
    claims,  cost  reports or  annual  filings required  to  be filed  to secure
    payments for services rendered by them under any third-party payment program
    from which  they receive  or expect  to receive  revenues except  where  the
    failure  to file such claim, report or other filing would not have a Company
    Material Adverse Effect.  Except as  indicated in  its financial  statements
    included in the Company SEC Reports (as hereinafter defined), the Company or
    its  subsidiaries,  as applicable,  have  paid, or  caused  to be  paid, all
    refunds, discounts, adjustments, or  amounts owing that  have become due  to
    such  third party  payors pursuant to  such claims, reports  or filings, and
    neither the Company nor any of its subsidiaries has any knowledge or  notice
    of  any material changes required to be  made to any cost reports, claims or
    filings made by them for any period or of any deficiency in any such  claim,
    report, or filing, except for changes and deficiencies that in the aggregate
    would not have a Company Material Adverse Effect.

    SECTION 3.07.  REPORTS; FINANCIAL STATEMENTS.

        (a) Since June 30, 1991, the Company and its subsidiaries have filed (i)

    statements  and  other  documents  required  to  be  filed  with  any  other
    Governmental  Entities, including,  without limitation,  state insurance and
    health regulatory authorities,  except where  the failure to  file any  such
    forms,  reports,  statements  or  other documents  could  not  reasonably be
    expected to have a Company Material Adverse Effect (all such forms, reports,
    statements and  other documents  in clauses  (i) and  (ii) of  this  Section
    3.07(a)  being referred to herein,  collectively, as the "Company Reports").
    The Company Reports  were prepared  in all material  respects in  accordance

    Company  SEC Reports did not at the  time they were filed contain any untrue
    statement of a material fact or omit to state a material fact required to be
    stated therein or necessary in order to make the statements therein, in  the
    light of the circumstances under which they were made, not misleading.

        (b)  Each of the  consolidated financial statements  (including, in each
    case, any related notes  thereto) contained in the  Company SEC Reports  (i)
    have been prepared in accordance with the published rules and regulations of
    the SEC and generally accepted accounting principles applied on a consistent
    basis  throughout the periods  involved (except (A)  to the extent disclosed

    regulations of the SEC) and  (ii) fairly present the consolidated  financial
    position  of the  Company and  its subsidiaries  as of  the respective dates
    thereof and the consolidated  results of operations and  cash flows for  the

    such consolidated financial statements are not necessarily indicative of the
    consolidated financial position of  the Company and  its subsidiaries as  of
    the  respective dates thereof and the consolidated results of operations and
    cash flows for the periods indicated.

                   REPRESENTATIONS AND WARRANTIES OF ACQUIROR

    The  Acquiror Companies hereby, jointly and severally, represent and warrant
to the Company that:

    SECTION 4.01.  ORGANIZATION  AND QUALIFICATION; SUBSIDIARIES.   Each of  the
Acquiror  Companies is a corporation, and  each of Acquiror's other subsidiaries
is a corporation or  partnership, duly organized, validly  existing and in  good
standing  under  the  laws of  its  jurisdiction  of incorporation  and  has all
requisite corporate power and authority to own, lease and operate its properties
and to carry on its business as it is now being conducted and is duly  qualified
and  in good standing to do business in each jurisdiction in which the nature of
the business conducted by it or the ownership or leasing of its properties makes
such qualification  necessary,  other than  where  the  failure to  be  so  duly
qualified  and in  good standing  could not  reasonably be  expected to  have an
Acquiror Material Adverse Effect. The term "Acquiror Material Adverse Effect" as
used in this  Agreement shall mean  any change or  effect that, individually  or
when  taken together with all such other changes or effects, would be materially
adverse to the financial condition, results of operations, business or prospects
of Acquiror and its subsidiaries, taken as  a whole, at the time of such  change
or  effect. Section  4.01of the  Disclosure Schedule  delivered by  the Acquiror
Companies to the Company concurrently with the execution of this Agreement  (the
"Acquiror  Disclosure Schedule") sets forth, as of the date of this Agreement, a
true and  complete list  of  all the  Acquiror's  directly or  indirectly  owned
subsidiaries,   together  with   (A)  the   jurisdiction  of   incorporation  or
organization  of  each  subsidiary  and  the  percentage  of  each  subsidiary's
outstanding capital stock or other equity interests owned by Acquiror or another
subsidiary  of Acquiror and (B) an indication of whether each such subsidiary is
a "Significant  Subsidiary" as  defined in  Section 9.03(f)  of this  Agreement.
Except as set forth in Section 4.01 of the Acquiror Disclosure Schedule, neither
Acquiror  nor any of its subsidiaries owns an equity interest in any partnership
or joint venture arrangement  or other business entity  that is material to  the
financial  condition, results of  operations, business or  prospects of Acquiror
and its subsidiaries, taken as a whole.

    SECTION 4.02.    CERTIFICATE OF  INCORPORATION  AND BYLAWS.    Acquiror  has
heretofore  furnished  or made  available to  the  Company complete  and correct
copies of the  Certificate of  Incorporation and  the Bylaws  or the  equivalent
organizational  documents,  in each  case  as amended  or  restated to  the date
hereof, of Acquiror and  each of its subsidiaries.  Neither Acquiror nor any  of
its  corporate subsidiaries  is in  violation of  any of  the provisions  of its
Certificate of Incorporation or Bylaws (or equivalent organizational Documents).
None of Acquiror s noncorporate subsidiaries  is in violation of any  provisions
of its organizational documents (the Acquiror Constituent Documents ) other than
any  such violations that could  not reasonably be expected  to have an Acquiror
Material Adverse Effect.

        (a) The authorized capital stock of Acquiror consists of (i) 150,000,000
    shares of  Acquiror  Common Stock,  of  which, as  of  March 28,  1995:  (A)

    validly issued,  fully  paid  and  nonassessable  and  were  not  issued  in

    interests  in, Acquiror or any of its subsidiaries or obligating Acquiror or
    any of its subsidiaries to  grant, issue or sell  any shares of the  capital
    stock of, or other equity interests in, Acquiror or any of its subsidiaries.
    Except  pursuant to  the terms  of the Acquiror  Rights Agreement  or as set
    forth in Section 4.03(a) of the  Acquiror Disclosure Schedule, there are  no

    issued  and,  in  the  case  of shares  of  capital  stock,  fully  paid and
    nonassessable, and has not been issued in  violation of (nor are any of  the

    Company or any of its subsidiaries is a party or is bound.

    Meeting, have been registered  under the Securities Act  and will have  been
    qualified  or registered or exempt therefrom under applicable Blue Sky Laws.
    In addition, the Acquiror  Common Stock will, prior  to the Effective  Time,
    have been registered under the Exchange Act and listed on the New York Stock

corporate power and authority to  execute and deliver the Transaction  Documents
(to  the  extent  a  party  thereto),  to  perform  its  obligations  under  the

Transaction  Documents  have been  duly executed  and delivered  by each  of the
Acquiror Companies  (to  the extent  a  party  thereto) and,  assuming  the  due

legal, valid and binding  obligation of each of  the Acquiror Companies (to  the

    SECTION 4.05.  NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

        (a)  Assuming that all consents,  licenses, permits, waivers, approvals,
    authorizations,  orders,  filings  and  notifications  contemplated  by  the
    exceptions  to Section 4.05(b) are obtained  or made and except as otherwise
    disclosed in  Section  4.05(a)  of the  Acquiror  Disclosure  Schedule,  the

    Incorporation or Bylaws, or the equivalent organizational documents, in each
    case as amended or restated, of Acquiror or any of Acquiror's  subsidiaries,
    (ii)  conflict with  or violate any  Laws in effect  as of the  date of this
    Agreement applicable to Acquiror or any of Acquiror's subsidiaries or by  or
    to  which any of their properties is bound or subject or (iii) result in any
    breach of or constitute a default (or  an event that with or without  notice
    or  lapse of time or  both would become a default)  under, or give to others
    any rights of  termination, amendment, acceleration  or cancellation of,  or
    require payment under, or result in the creation of a lien or encumbrance on
    any   of  the  properties  or  assets  of  Acquiror  or  any  of  Acquiror's
    subsidiaries pursuant  to, any  note, bond,  mortgage, indenture,  contract,
    agreement,   lease,  license,  permit,  franchise  or  other  instrument  or
    obligation to which Acquiror or any of Acquiror's subsidiaries is a party or
    by or to which Acquiror  or any of Acquiror's  subsidiaries or any of  their
    respective  properties is bound  or subject, except  for any such conflicts,
    violations, breaches, defaults,  events, rights  of termination,  amendment,
    acceleration  or cancellation, payment obligations  or liens or encumbrances
    that could not reasonably be expected  to have an Acquiror Material  Adverse
    Effect.

        (b)  Except as disclosed  in Section 4.05(b)  of the Acquiror Disclosure
    Schedule, the execution and delivery of the Transaction Documents by each of
    the Acquiror  Companies does  not, and  the performance  of the  Transaction
    Documents  by each of  the Acquiror Companies  will not, require  any of the
    Acquiror Companies to obtain any consent, license, permit, waiver  approval,
    authorization  or order of, or  to make any filing  with or notification to,
    any Governmental Entities, except (i)  for applicable requirements, if  any,
    of  the Securities Act, the Exchange Act, Blue  Sky Laws and the HSR Act and
    the filing and recordation  of appropriate merger  documents as required  by
    Delaware  Law and (ii) where the  failure to obtain such consents, licenses,
    permits, waivers,  approvals,  authorizations or  orders,  or to  make  such
    filings  or notifications could not reasonably be expected to prevent any of
    the Acquiror Companies from performing its obligations under the Transaction
    Documents and could not reasonably be expected to have an Acquiror  Material
    Adverse Effect.

    SECTION 4.06.  PERMITS; COMPLIANCE.

        (a)  Each of Acquiror and  its subsidiaries is in  possession of all (i)
    franchises, grants, authorizations, licenses, permits, easements, variances,
    exemptions, consents, certificates, identification and registration numbers,
    approvals and orders necessary to own, lease and operate its properties  and
    to  carry on its business  as it is now  being conducted and (ii) agreements
    from all federal, state and local governmental agencies and accrediting  and
    certifying   organizations  having   jurisdiction  over   such  facility  or
    facilities that are required  to operate the facility  or facilities in  the
    manner  in which it or they are currently operated and receive reimbursement
    for care provided to patients covered under the federal Medicare program  or
    any   applicable  state   Medicaid  program   (collectively,  the  "Acquiror
    Permits"), except where the failure  to possess such Acquiror Permits  could
    not  reasonably be  expected to  have an  Acquiror Material  Adverse Effect.
    Without  limiting  the  generality  of  the  foregoing,  all  of  Acquiror's
    hospitals  are  certified for  participation or  enrollment in  the Medicare
    program, have  a  current and  valid  provider contract  with  the  Medicare
    program   and  are  in   substantial  compliance  with   the  conditions  of
    participation of such programs. Neither Acquiror nor any of its subsidiaries
    has received  notice  from  the  regulatory  authorities  that  enforce  the
    statutory  or regulatory provisions in respect of either the Medicare or the
    Medicaid program of any pending or threatened investigations or surveys, and
    no such investigations or

                                      A-17
<PAGE>
    surveys are pending or, to the knowledge of Acquiror, threatened or imminent
    that could  reasonably be  expected  to have  an Acquiror  Material  Adverse
    Effect.  Section 4.06 of Acquiror Disclosure  Schedule sets forth, as of the
    date of this Agreement, all actions, proceedings, investigations or  surveys
    pending or, to the knowledge of Acquiror, threatened against Acquiror or any
    of  its subsidiaries that could reasonably be  expected to result in (i) the
    loss or revocation of  an Acquiror Permit necessary  to operate one or  more
    facilities  or for a facility to receive reimbursement under the Medicare or
    Medicaid programs, (ii) the suspension or cancellation of any other Acquiror
    Permit except any such Acquiror Permit where such suspension or cancellation
    could not  reasonably  be expected  to  have an  Acquiror  Material  Adverse
    Effect. Neither Acquiror nor any of its subsidiaries is in conflict with, or
    in  default or violation of (1) any Law applicable to Acquiror or any of its
    subsidiaries or by or to which  any of their respective properties is  bound
    or  subject or (2) any  of Acquiror Permits, except  for any such conflicts,
    defaults or violations  that could  not reasonably  be expected  to have  an
    Acquiror  Material Adverse Effect. Since June 30, 1993, neither Acquiror nor
    any of  its  subsidiaries has  received  from any  Governmental  Entity  any
    written  notification  with  respect  to  possible  conflicts,  defaults  or
    violations  of  Laws,  except  for  written  notices  relating  to  possible
    conflicts,  defaults or violations that could  not reasonably be expected to
    have an Acquiror Material Adverse Effect.

        (b)  Acquiror  and  its  subsidiaries,  as  appropriate,  are   approved
    participating  providers in and under all  third party payment programs from
    which they receive revenues.  No action or investigation  is pending, or  to
    the  best  of  its  knowledge,  threatened  to  suspend,  limit,  terminate,
    condition, or revoke the status of Acquiror or any of its subsidiaries as  a
    provider  in  any  such  program,  and  neither  Acquiror  nor  any  of  its
    subsidiaries has  been provided  notice  by any  third  party payor  of  its
    intention  to suspend, limit, terminate, revoke,  condition or fail to renew
    in whole or in  part or decrease the  amounts payable under any  arrangement
    with  Acquiror or such subsidiary as a provider, which action, investigation
    or proceeding would have an Acquiror Material Adverse Effect.

        (c) Acquiror  and its  subsidiaries have  filed on  a timely  basis  all
    claims,  cost  reports or  annual  filings required  to  be filed  to secure
    payments for services rendered by them under any third-party payment program
    from which  they receive  or expect  to receive  revenues except  where  the
    failure  to  file such  claim,  report or  other  filing would  not  have an

    in subsection (c)(i) above, such party shall use all reasonable efforts, and
    shall take any such  actions reasonably requested by  the other parties,  to
    limit  the adverse  effect upon the  Company and  Acquiror, their respective
    subsidiaries, and  their respective  businesses  resulting, or  which  could
    reasonably  be expected to result after the Effective Time, from the failure
    to obtain such consent.

    SECTION 6.07.  RIGHTS AGREEMENT; STATE TAKEOVER STATUTES.  The Company shall
take  all  action (including,  if necessary,  redeeming  all of  the outstanding

        (a) At the Effective Time, automatically  and without any action on  the
    part  of the holder thereof, each  outstanding Company Stock Option shall be

    of  Acquiror Common  Stock obtained by  multiplying the number  of shares of
    Company Common Stock issuable upon the exercise of such option by the Common
    Stock Exchange Ratio at an exercise price  per share equal to the per  share
    exercise price of such option divided by the Common Stock Exchange Ratio and
    otherwise  upon the same terms and conditions as such outstanding options to
    purchase Company Common Stock;  provided, however, that in  the case of  any
    option to which Section 421of the Internal Revenue Code applies by reason of
    the  qualifications  under Section  422 or  423 of  such Code,  the exercise
    price, the number  of shares  purchasable pursuant  to such  option and  the
    terms and conditions of exercise of such option shall be determined in order
    to comply with Section 424(a) of the Code.

        (b)   At  the  Effective  Time,  subject  to  the  any  requirements  or
    restrictions necessary  in order  for  the Merger  to constitute  a  Pooling
    Transaction,  automatically  and  without  any action  by  any  person, each
    outstanding Company Stock Option then held by an employee of the Company  or
    any  of its subsidiaries and  granted prior to January  1, 1995 shall become
    immediately exercisable.

        (c) The Acquiror shall take  all corporate actions necessary to  reserve

        (d)  As promptly as practicable after the Effective Time, Acquiror shall
    file a  Registration Statement  on Form  S-8, as  the case  may be  (or  any
    successor or other appropriate forms) with respect to the shares of Acquiror
    Common  Stock subject to  the Company Stock  Options and shall  use its best
    efforts to  maintain the  effectiveness of  such registration  statement  or
    registration  statements (and maintain the  current status of the prospectus
    or prospectuses  contained  therein) for  so  long as  such  options  remain
    outstanding.

        (e)  Except as provided herein or as otherwise agreed to by the parties,
    each of the Company Stock Option  Plans providing for the issuance or  grant
    of  options in respect  to the stock of  Company shall be  assumed as of the
    Effective Time  by the  Acquiror  with such  amendments  thereto as  may  be
    required to reflect the Merger.

        (f) In connection with the submission of the Acquiror Proxy Statement to
    its  stockholders, the Acquiror shall seek  such stockholder approval as may
    be necessary so that grants of options and issuances of securities  pursuant
    to the exercise of such options under the Company Stock Option Plans assumed
    by  it hereunder, as amended, and all other Company Stock Option Plans as in
    effect on the date hereof shall qualify for the exemption for such issuances
    provided by Rule 16b-3 under the Exchange Act.

        (g) At or  prior the Effective  Time the Acquiror  shall (i) assume  and
    agree   to   perform  the   Company   s  obligations   under   its  existing

    of  the Company Disclosure  Schedule, upon exercise of  the Warrant and upon
    conversion of  the Company  Debenture, in  each case  in lieu  of shares  of
    Company Common Stock, the number of shares to be so issued to be obtained by
    multiplying  the number of shares of Company Common Stock otherwise issuable
    thereunder by  the Common  Stock Exchange  Ratio and  the purchase  of  such
    shares  of Acquiror Common Stock, if  applicable, to be obtained by dividing
    the per share purchase price of a share of Acquiror Common Stock  thereunder

Acquiror) or liabilities.

    SECTION  6.11.  BOARD OF DIRECTORS.  Acquiror shall take action to cause the
number of directors on the Acquiror Board  at the Effective Time to be  thirteen
and  to  ensure  that five  of  such  directorships be  filled  with individuals

subsidiary  following the  Effective Time), and  (iii) a  third Company Designee
who, immediately after being elected to the Acquiror Board, shall be elected  to
the  Executive Committee thereof.  The Company Designees  shall be nominated for
election as directors of Acquiror at the first annual meeting of stockholders of
the Acquiror  subsequent  to the  Effective  Time  and shall  be  nominated  for

    reasonable  attorney's  fees  and  costs  of  investigation)  to  which  any
    indemnified  party may become subject under the Securities Act, the Exchange
    Act or  otherwise, insofar  as such  loss, claim,  damage, cost,  liability,
    obligation  or expense  or actions  in respect thereof  arises out  of or is
    based upon any untrue  statement or alleged untrue  statement of a  material
    fact  relating to such indemnifying party  and contained in the Registration
    Statement or arises out of or is based upon the omission or alleged omission
    to state therein a material fact required to be stated therein or  necessary
    to  make the statements therein with  respect to such indemnifying party not
    misleading.

           (b) (i) The Company and Acquiror agree that, until six years from the
       Effective Time,  the  Certificates of  Incorporation  and Bylaws  of  the
       Company and Acquiror as in effect immediately after the amendments to the
       Certificate  of Incorporation of the Company contemplated by Section 1.04
       have become effective shall not be amended to reduce or limit the  rights
       of indemnity afforded to the present and former directors and officers of
       the  Company and Acquiror thereunder or as to the ability of Acquiror and
       the Company to indemnify such persons,  or to hinder, delay or make  more
       difficult  the exercise  of such  rights of  indemnity or  the ability to
       indemnify. The  Company  and Acquiror  agree  that the  Company,  as  the
       surviving corporation of the Merger will at all times exercise the powers
       granted  to it  by its  Certificate of  Incorporation, its  Bylaws and by
       applicable law to  indemnify to  the fullest extent  possible present  or
       former  directors, officers, employees and  agents of the Company against
       claims made against them arising from their service in such capacities.

                                      A-34
<PAGE>
           (ii) Should any claim or claims be made against any present or former
       director, officer, employee or agent of the Company or Acquiror,  arising
       from  his services as such,  within six years of  the Effective Time, the
       provisions  of  this  Section  6.12(b)  respecting  the  Certificates  of
       Incorporation  and Bylaws of  Acquiror and the  Company shall continue in
       effect until the  final disposition of  all such claims.  Notwithstanding
       anything  to the contrary in this  Section 6.12, neither Acquiror nor the
       Company shall be liable for  any settlement effected without its  written
       consent, which shall not be unreasonably withheld.

          (iii)  The provisions of  this Section 6.12(b) are  intended to be for
       the benefit  of, and  shall be  enforceable by,  each party  entitled  to
       indemnification hereunder, his heirs and his representatives.

        (c) Acquiror shall cause to be maintained in effect until six years from
    the  Effective  Time  the  current  policies  of  directors'  and  officers'
    liability insurance  maintained  by  the  Company  (or  substitute  policies
    providing  at least  the same coverage  and limits and  containing terms and
    conditions that are not materially less advantageous) with respect to claims
    arising from  facts or  events  which occurred  before the  Effective  Time;
    provided, however that in no event shall Acquiror or the Company be required
    to  expend more than 200% of the current annual premiums paid by the Company
    for such insurance.

    if shorter, for 30 days), the Company may not terminate this Agreement under
    this Section 8.01(c);

        (d) by either Acquiror or the Company, if there shall be any Order which

    if the party seeking to terminate  this Agreement has not complied with  its
    obligations under Section 6.03(b) of this Agreement;

        (e) by either Acquiror or the Company, if the Merger shall not have been

    may  be extended by  written notice of  either Acquiror or  the Company to a
    date not  later than  March 31,  1996, if  the Merger  shall not  have  been

    Order;

available,  will not  be an  adequate remedy.  Accordingly, each  of the parties
hereto hereby consents  to the  issuance of injunctive  relief by  any court  of
competent  jurisdiction to compel performance of  any party's obligations and to
the granting by any  such court of  the remedy of  specific performance of  such
party's obligations hereunder.

                             AFFILIATE'S AGREEMENT

Horizon Healthcare Corporation
6001 Indian School Road, N.E., Suite 530
Albuquerque, N.M. 87110
Gentlemen:

    I  have been advised that  as of the date  hereof, I may be  deemed to be an
"affiliate" of Continental  Medical Systems, Inc.,  a Delaware corporation  (the
"Company"),  as that term is  defined for purposes of  paragraphs (c) and (d) of
Rule 145  of the  Rules and  Regulations (the  "Rules and  Regulations") of  the
Securities and Exchange Commission (the "SEC") under the Securities Act of 1933,
as amended (the "Securities Act").

    I  understand that pursuant  to the terms  and subject to  the conditions of
that certain  Agreement and  Plan  of Merger  by  and among  Horizon  Healthcare
Corporation,  a  Delaware corporation  ("Acquiror"),  CMS Merger  Corporation, a
Delaware corporation and wholly owned subsidiary of Acquiror ("Merger Sub"), and
the Company dated as of March 31, 1995 (the "Merger Agreement"), providing  for,
among  other things,  the merger of  Merger Sub  with and into  the Company (the
"Merger"), I will be entitled to receive shares of common stock, par value $.001
per share  ("Acquiror Common  Stock"), of  Acquiror in  exchange for  shares  of
common  stock, par value $.01 per share ("Company Common Stock"), of the Company
owned by  me at  the effective  time of  the Merger  (the "Effective  Time")  as
determined pursuant to the Merger Agreement.

    I  further  understand  that  the  Merger  will  be  treated  for  financial
accounting purposes as  a "pooling  of interests" in  accordance with  generally
accepted  accounting principles and that the staff of the SEC has issued certain
guidelines that should be followed to ensure the pooling of the entities.

    I hereby represent  and warrant that,  since 30 days  before closing to  and
including the date hereof, I have not sold, transferred or otherwise disposed of
any shares of Company Common Stock.

    In  consideration of the agreements contained herein, Acquiror's reliance on
this letter in connection with the consummation of the Merger and for other good
and valuable  consideration, the  receipt and  sufficiency of  which are  hereby
acknowledged, I hereby represent, warrant and agree that (i) I will not make any
sale, transfer or other disposition of Company Common Stock prior to the earlier
of  the Effective Time and the termination  of the Merger Agreement, (ii) I will
not make  any sale,  transfer  or other  disposition  of Acquiror  Common  Stock
received  by me pursuant to the Merger or  otherwise owned by me until such time
as financial results that include at least 30 days of combined operations of the
Company and Acquiror after the Merger shall have been published, unless I  shall
have   delivered  to  Acquiror  prior  to  any  such  sale,  transfer  or  other
disposition, a  written opinion  from Arthur  Andersen LLP,  independent  public
accountants  for Acquiror,  or a  written no-action  letter from  the accounting
staff of the SEC, in either  case in form and substance reasonably  satisfactory
to  Acquiror, to the effect  that such sale, transfer  or other disposition will
not cause the Merger not to be treated as a "pooling of interests" for financial
accounting purposes in accordance with generally accepted accounting principles,
the Rules and Regulations and  interpretations of the SEC  and (iii) I will  not
make  any sale, transfer or  other disposition of any  shares of Acquiror Common
Stock received by me pursuant to the  Merger in violation of the Securities  Act
or  the Rules  and Regulations.  I have  been advised  that the  issuance of the
shares of Acquiror Common Stock pursuant to the Merger will have been registered
with the SEC under the Securities Act on a Registration Statement on Form S-4. I
have also been advised, however, that since  I may be deemed to be an  affiliate
of  the  Company  at  the  time  the Merger  is  submitted  for  a  vote  of the
stockholders of the Company, the Acquiror  Common Stock received by me  pursuant
to  the Merger can be sold by me  only (i) pursuant to an effective registration
statement

                                      A-44
<PAGE>
under the  Securities  Act,  (ii)  in  conformity  with  the  volume  and  other
limitations  of Rule  145 promulgated  by the SEC  under the  Securities Act, or
(iii) in reliance upon  an exemption from registration  that is available  under
the Securities Act.

    I  also understand  that instructions will  be given  to Acquiror's transfer
agent with respect to the Acquiror Common Stock to be received by me pursuant to
the Merger and that there will  be placed on the certificates representing  such
shares of Acquiror Common Stock, or any substitutions therefor, a legend stating
in substance as follows:

    "These shares were issued in a transaction to which Rule 145 promulgated
    under  the  Securities Act  of 1933  applies. These  shares may  only be
    transferred in accordance with the terms of such Rule and an Affiliate's
    Agreement between  the  original  holder  of  such  shares  and  Horizon
    Healthcare  Corporation, a  copy of  which agreement  is on  file at the
    principal offices of Horizon Healthcare Corporation."

    It is understood and agreed that the legend set forth above shall be removed
upon surrender of  certificates bearing  such legend by  delivery of  substitute
certificates  without  such legend  if  I shall  have  delivered to  Acquiror an
opinion of counsel, in form  and substance reasonably satisfactory to  Acquiror,
to  the effect that (i) the sale or disposition of the shares represented by the
surrendered certificates may be effected  without registration of the  offering,
sale  and delivery of such shares under  the Securities Act, and (ii) the shares
to be  so  transferred  may be  publicly  offered,  sold and  delivered  by  the
transferee  thereof without compliance  with the registration  provisions of the
Securities Act.

    By its execution hereof, Acquiror agrees that it will, as long as I own  any
Acquiror  Common Stock  to be received  by me  pursuant to the  Merger, take all
reasonable efforts to make timely filings  with the SEC of all reports  required
to  be filed by it pursuant to the  Securities Exchange Act of 1934, as amended,
and will promptly  furnish upon  written request  of the  undersigned a  written
statement confirming that such reports have been so timely filed.

    If  you are in agreement  with the foregoing, please  so indicate by signing
below and returning a copy of this letter to the undersigned, at which time this
letter shall become a binding agreement between us.

                                         Very truly yours,

Gentlemen:

    I have been advised  that as of the  date hereof, I may  be deemed to be  an

    I  further  understand  that  the  Merger  will  be  treated  for  financial

Board of Directors
Horizon Healthcare Corporation
6001 Indian School Road, N.E., Suite 530
Albuquerque, New Mexico 87110

Dear Sirs:

    You have requested our opinion as to the fairness, from a financial point of
view, to the holders of common stock, par value $.001 per share ("Horizon Common
Stock"),  of Horizon Healthcare Corporation ("Horizon"), of the consideration to
be paid by Horizon in connection with the proposed merger (the "Merger") of  CMS
Merger  Corporation, a wholly  owned subsidiary of  Horizon ("Merger Sub"), with
and into  Continental Medical  Systems,  Inc. (the  "Company") pursuant  to  the
Amended  and Restated Agreement and Plan of Merger dated as of May 23, 1995 (the
"Merger Agreement"), by and  among Horizon, Merger Sub  and the Company. In  the
Merger,  each share of common  stock, par value $.01  per share ("Company Common
Stock"), of  the  Company  issued  and  outstanding  immediately  prior  to  the
effectiveness  of the Merger  (subject to certain  exceptions) will be converted
into     of one share of Horizon Common Stock. We understand that the Merger  is
intended  to  be accounted  for as  a  pooling of  interests in  accordance with
generally accepted accounting principles  as described in Accounting  Principles
Board Opinion Number 16.

    In  arriving at our opinion,  we have reviewed the  Merger Agreement and its
related exhibits and schedules. We also have reviewed certain publicly available
business and financial information relating to Horizon and the Company, as  well
as certain other information, including financial projections, provided to us by
Horizon  and the Company. We have discussed  the past and current operations and
financial condition and  prospects of Horizon  and the Company  with members  of
senior  management  of  such  companies.  We  have  also  considered  such other
information,  financial   studies,  analyses,   investigations  and   financial,
economic, market and trading criteria which we deemed relevant.

    We  have  assumed  and  relied  on  the  accuracy  and  completeness  of the
information reviewed by  us for  the purpose  of this  opinion and  we have  not
assumed  any responsibility for independent  verification of such information or
for any independent  evaluation or  appraisal of the  assets of  Horizon or  the
Company.  With respect to Horizon's and  the Company's financial projections, we
have assumed that  they have been  reasonably prepared on  bases reflecting  the
best  currently available estimates and judgments of Horizon's and the Company's
management and  we express  no opinion  with respect  to such  forecasts or  the
assumptions on which they are based, including assumptions regarding the effects
of  any outstanding or potential  litigation, investigations, inquiries or other
actions. Our opinion is  necessarily based upon  business, market, economic  and
other  conditions as they exist on, and can be evaluated as of, the date of this
letter and does not address Horizon's underlying business decision to effect the
Merger or constitute a recommendation to  any holder of Horizon Common Stock  as
to  how  such holder  should vote  with respect  to the  Merger. Our  opinion as
expressed below does not imply any conclusion as to the likely trading range for
the Horizon Common  Stock following the  consummation of the  Merger, which  may
vary  depending on,  among other  factors, changes  in interest  rates, dividend
rates, market conditions,  general economic  conditions and  other factors  that
generally influence the price of securities.

                                      B-1
<PAGE>
    We  have acted as financial advisor to  the Board of Directors of Horizon in
connection with the Merger and received a fee for our services which was payable
upon the earlier submission of an opinion substantially similar to this opinion.
In the ordinary course of  our business, we actively  trade the debt and  equity
securities  of Horizon and the Company, 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.

    Based  upon and subject to the foregoing, it  is our opinion that, as of the
date hereof, the  consideration to  be paid by  Horizon in  connection with  the
Merger  is fair to the holders of Horizon Common Stock from a financial point of
view.

                                          Very truly yours,

Board of Directors
Continental Medical Systems, Inc.
600 Wilson Lane
Mechanicsburg, Pennsylvania 17055

Gentlemen:

    Continental  Medical Systems, Inc., a  Delaware corporation (the "Company"),
Horizon Healthcare Corporation, a Delaware corporation (the "Acquiror"), and CMS
Merger Corporation, a Delaware corporation and a wholly owned subsidiary of  the
Acquiror  (the "Merger Sub"), have  entered into an agreement  dated as of March
31, 1995, as amended and  restated as of May  23, 1995 (the "Merger  Agreement")
pursuant  to  which  the  Company  will  be merged  with  the  Merger  Sub  in a
transaction (the "Merger") in  which each share of  the Company's common  stock,
par  value $.01 per  share (the "Shares"),  will be converted  into the right to
receive .5397 shares (the "Exchange Ratio") of the common stock, par value $.001
per share,  of the  Acquiror (the  "Acquiror Shares").  In connection  with  the
Merger,  the Company and the Acquiror also  have entered into an agreement dated
as of March  31, 1995  (the "Option Agreement")  pursuant to  which the  Company
granted  the Acquiror an option to acquire  15% of the total Shares outstanding.
Also in connection with the Merger, the Acquiror and certain stockholders of the
Company have entered into an agreement dated  as of March 31, 1995 (the  "Voting
Agreement")  pursuant to which such stockholders  agreed to vote their Shares in
favor of the Merger.

    You have asked us  whether, in our opinion,  the proposed Exchange Ratio  is
fair to the Company's stockholders from a financial point of view.

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

   
     (1)  Reviewed   the  Company's  Annual  Reports,  Forms  10-K  and  related
          financial information for the  five fiscal years  ended June 30,  1994
          (and, with respect to the Form 10-K for the fiscal year ended June 30,
          1994,  the amendment  thereto) and  the Company's  Forms 10-Q  and the
          related unaudited  financial  information for  the  quarterly  periods
          ended  September 30, 1994,  December 31, 1994 and  March 31, 1995 (and
          the amendments thereto);
    
   
     (2)  Reviewed  the  Acquiror's  Annual  Reports,  Forms  10-K  and  related
          financial  information for  the five fiscal  years ended  May 31, 1994

     (6)  Reviewed the historical  market prices  and trading  activity for  the
          Shares  and the Acquiror Shares and compared them with that of certain
          publicly traded companies which we deemed to be reasonably similar  to
          the Company and the Acquiror, respectively;

     (7)  Compared  the results  of operations of  the Company  and the Acquiror
          with that  of  certain companies  which  we deemed  to  be  reasonably
          similar to the Company and the Acquiror, respectively;

     (8)  Compared the proposed financial terms of the transactions contemplated
          by the Agreement with the financial terms of certain other mergers and
          acquisitions which we deemed to be relevant;

     (9)  Reviewed the Merger Agreement;

    (10)  Reviewed the Option Agreement;

    (11)  Reviewed the Voting Agreement; and

    (12)  Reviewed  such other financial studies and analyses and performed such
          other investigations and took  into account such  other matters as  we
          deemed necessary, including our assessment of general economic, market
          and monetary conditions.

    In preparing our opinion, we have relied on the accuracy and completeness of
all  information supplied or otherwise  made available to us  by the Company and
the Acquiror,  and  we  have  not independently  verified  such  information  or
undertaken  an independent appraisal of the assets or liabilities of the Company
or the  Acquiror. With  respect  to the  financial  forecasts furnished  by  the
Company  and  the  Acquiror, we  have  assumed  that they  have  been reasonably
prepared and reflect the best currently available estimates and judgment of  the
management  of the Company or  the Acquiror as to  the expected future financial
performance of the Company or the Acquiror,  as the case may be. Moreover,  with
respect  to the  estimates of potential  synergies furnished by  the Company, we
have assumed  that they  have  been reasonably  prepared  and reflect  the  best
currently  available estimates and judgment of  the management of the Company as
to the potential synergies  to be realized  as a result of  the Merger. We  have
also  assumed that the  Merger will qualify  for pooling-of-interests accounting
treatment and as a tax-free transaction for the stockholders of the Company.

    In connection  with  the preparation  of  this  opinion, we  have  not  been
authorized  by the  Company or the  Board of  Directors to solicit,  nor have we
solicited, third-party indications of interest for the acquisition of all or any
part of the Company.

    We have, in  the past,  provided financial advisory  and investment  banking
services to the Company and investment banking services to the Acquiror and have
received  fees for  the rendering  of such services.  In the  ordinary course of
business, we  may actively  trade the  securities of  both the  Company and  the
Acquiror  for our own account and the account of our customers and, accordingly,
may at any time hold a long or  short position in securities of the Company  and
the Acquiror.

    On  the basis of, and  subject to the foregoing, we  are of the opinion that
the proposed  Exchange  Ratio is  fair  to  the Company's  stockholders  from  a
financial point of view.

                                          Very truly yours,
                                          MERRILL LYNCH, PIERCE, FENNER &
                                               SMITH INCORPORATED
