                                  COMMON STOCK
                                 --------------
                                      

     This Prospectus  covers the issuance and sale of up to 3,579,766  shares of
Common  Stock,  $.001 par value per share  (together  with the  Preferred  Stock
Purchase Rights associated therewith,  the "Common Stock"), of Integrated Health
Services, Inc., a Delaware corporation ("IHS" or the "Company"), issuable either
to (a) holders of outstanding 6% Convertible Subordinated Debentures due 2003 of
the Company (the "Debentures")  upon conversion of the Debentures,  or (b) Smith
Barney Inc. (the  "Purchaser")  pursuant to the standby  arrangements  described
herein and the resale from time to time by the  Purchaser  of any such shares of
Common Stock.

     The Company  has called for  redemption  on June 29, 1998 (the  "Redemption
Date") all Debentures at a redemption  price of 103.0% of the principal  amount,
plus accrued  interest of $29.83 from January 1, 1998 to the Redemption Date for
each $1,000 principal amount of Debentures,  making a total of $1,059.83 payable
for each such $1,000  principal  amount.  Prior to 5:00 p.m.  New York City time
(the "Close of Business") on the  Redemption  Date, at the option of the holder,
the Debentures (or any portion  thereof which is $1,000 or an integral  multiple
thereof)  may be  converted  into  shares of Common  Stock of the  Company  at a
conversion  price of  $32.125  per share of Common  Stock  (equivalent  to 31.13
shares of Common Stock for each $1,000  principal  amount of  Debentures).  Cash
will be paid in lieu of any  fractional  shares of Common  Stock  issuable  upon
conversion of the Debentures.  Debentures surrendered for conversion will not be
entitled to  interest  accrued to the date of  conversion.  See  "Redemption  of
Debentures and  Alternatives to  Redemption."  ANY DEBENTURES NOT SO SURRENDERED
FOR  CONVERSION  PRIOR TO THE CLOSE OF BUSINESS ON THE  REDEMPTION  DATE WILL BE
REDEEMED FOR CASH ON THE REDEMPTION  DATE AND NO FURTHER  INTEREST SHALL ACCRUE.
After  the  Redemption  Date,  the  Debentures  will no  longer  be deemed to be
outstanding and all rights of the holders of the Debentures  will cease,  except
the right to receive the redemption  price,  without interest from and after the
Redemption Date, upon surrender of the Debentures.

   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE

May  , 1998

Information   contained  herein  is  subject  to  completion  or  amendment.   A
registration  statement  relating  to these  securities  has been filed with the
Securities  and Exchange  Commission.  These  securities may not be sold nor may
offers to buy be accepted prior to the time the registration  statement  becomes
effective.  This  prospectus  shall  not  constitute  an  offer  to  sell or the
solicitation of an offer to buy nor shall there be any sale of these  securities
in any State in which such offer,  solicitation  or sale would be unlawful prior
to registration or qualification under the securities laws of any such State.



(continued from previous page)
     The Common Stock is traded on the New York Stock  Exchange  ("NYSE")  under
the symbol  "IHS." On May 28,  1998,  the reported  closing  price of the Common
Stock on the NYSE  Composite Tape was $38.1875 per share. A holder of Debentures
who converted such Debentures on that date would have received Common Stock (and
cash in lieu of a fractional  share) having a market value,  based on such price
on that date, of  approximately  $1,188.78 for each $1,000  principal  amount of
Debentures converted.  If such Debentures were surrendered for redemption on the
Redemption  Date,  such holder would  receive  $1,059.83 in cash for each $1,000
principal amount.

     AS LONG AS THE MARKET PRICE OF THE COMMON STOCK  REMAINS AT OR ABOVE $34.05
PER SHARE,  THE HOLDERS OF DEBENTURES  WHO ELECT TO CONVERT WILL  RECEIVE,  UPON
CONVERSION, COMMON STOCK (INCLUDING CASH, IF ANY, RECEIVED IN LIEU OF FRACTIONAL
SHARES)  HAVING A GREATER MARKET VALUE THAN THE AMOUNT OF CASH  RECEIVABLE  UPON
REDEMPTION OF SUCH DEBENTURES (BEFORE DEDUCTING ANY TAXES, COMMISSIONS AND OTHER
COSTS WHICH WOULD LIKELY BE INCURRED ON SALE OF THE COMMON STOCK  RECEIVED  UPON
CONVERSION OF THE DEBENTURES).  IT SHOULD BE NOTED,  HOWEVER,  THAT THE PRICE OF
THE COMMON STOCK  RECEIVED  UPON  CONVERSION  WILL  FLUCTUATE IN THE MARKET.  NO
ASSURANCE  CAN BE GIVEN AS TO THE PRICE OF THE COMMON  STOCK AT ANY FUTURE TIME,
AND THE HOLDERS  SHOULD EXPECT TO INCUR VARIOUS  EXPENSES OF SALE IF SUCH COMMON
STOCK IS SOLD.

     The  conversion  right  expires at the Close of Business on the  Redemption
Date, time being of the essence.  From and after that date and time,  holders of
Debentures will be entitled only to the redemption price,  without interest from
and after the Redemption Date.

     The  Company  has  entered  into a  standby  purchase  agreement  with  the
Purchaser  pursuant  to which the  Purchaser  has  agreed,  subject  to  certain
conditions,  to purchase  from the Company such number of shares of Common Stock
(the  "Purchased  Shares") as would have been  issuable  upon the  conversion of
those  Debentures  which have not been duly  surrendered  for  conversion by the
Close of Business on the  Redemption  Date. The purchase price for the Purchased
Shares will be an amount equal to a price per share of $34.05. The Purchaser may
also purchase  Debentures in the open market or otherwise  prior to the Close of
Business on the Redemption Date. The Purchaser has agreed to convert into Common
Stock all Debentures owned by it or so acquired.  See "Standby Arrangements" for
a description of the Purchaser's  compensation and indemnification  arrangements
with the Company.

                                --------------

     Prior to and after the  Redemption  Date, the Purchaser may offer shares of
Common Stock,  including shares of Common Stock acquired pursuant to the standby
arrangements  or upon the  conversion of  Debentures,  directly to the public at
prices set from time to time by the Purchaser. The Purchaser may also make sales
to dealers at prices which  represent a concession from the prices at which such
shares of Common Stock are then being offered to the public.  The amount of such
concessions will be determined from time to time by the Purchaser.  In effecting
such  transactions,  the Purchaser may realize profits or losses  independent of
the compensation  described under "Standby  Arrangements."  Any shares of Common
Stock will be offered by the Purchaser when, as and if accepted by the Purchaser
and subject to the Purchaser's  right to reject orders in whole or in part. This
Prospectus  does not constitute an offer to sell any  securities  other than the
Common Stock offered by the Purchaser.  The Common Stock and any shares acquired
through  conversion of Debentures are listed,  and application  will be made for
listing of the Purchased Shares, on the NYSE.

                                --------------

     CERTAIN PERSONS  PARTICIPATING  IN THIS OFFERING MAY ENGAGE IN TRANSACTIONS
THAT  STABILIZE,  MAINTAIN OR  OTHERWISE  AFFECT THE PRICE OF THE COMMON  STOCK,
INCLUDING   OVERALLOTMENT,   ENTERING   STABILIZING  BIDS,   EFFECTING  COVERING
TRANSACTIONS AND IMPOSING  PENALTY BIDS. FOR A DESCRIPTION OF THESE  ACTIVITIES,

                                  THE COMPANY

     Integrated  Health  Services,  Inc.  ("IHS" or the "Company") is one of the
nation's leading providers of post-acute healthcare services. Post-acute care is
the  provision of a continuum of care to patients  following  discharge  from an
acute care  hospital.  IHS'  post-acute  care services  include  subacute  care,
skilled nursing facility care, home respiratory  care, home health nursing care,
other homecare services and contract  rehabilitation,  hospice,  lithotripsy and
diagnostic  services.  The  Company's  post-acute  care  network is  designed to
address  the fact that the cost  containment  measures  implemented  by  private
insurers  and  managed  care   organizations   and   limitations  on  government
reimbursement of hospital costs have resulted in the discharge from hospitals of
many  patients who continue to require  medical and  rehabilitative  care.  IHS'
post-acute healthcare system is intended to provide cost-effective continuity of
care for its patients in multiple  settings and enable  payors to contract  with
one provider to provide all of a patient's needs following  discharge from acute
care  hospitals.  The Company  believes that its post-acute  care network can be
extended beyond post-acute care to also provide "pre-acute" care, i.e., services
to patients  which reduce the  likelihood  of a need for a hospital  stay.  IHS'
post-acute  care  network  currently  consists of  approximately  2,000  service
locations in 47 states and the District of Columbia.

     The Company's post-acute care network strategy is to provide cost-effective
continuity of care for its patients in multiple  settings,  using geriatric care
facilities  as  platforms  to provide a wide  variety of  subacute  medical  and
rehabilitative  services  more  typically  delivered in the acute care  hospital
setting and using home  healthcare to provide  those medical and  rehabilitative
services which do not require  24-hour  monitoring.  To implement its post-acute
care network strategy,  IHS has focused on (i) developing  market  concentration
for its  post-acute  care services in targeted  states due to  increasing  payor
consolidation  and the increased  preference of payors,  physicians and patients
for dealing with only one service  provider;  (ii)  expanding  the range of home
healthcare  and  related  services  it offers to  patients  directly in order to
provide patients with a continuum of care throughout  their recovery,  to better
control  costs and to meet the growing  desire by payors for one-stop  shopping;
and (iii)  developing  subacute care units.  Given the increasing  importance of
managed care in the healthcare  marketplace  and the continued cost  containment
pressures  from  Medicare,  Medicaid  and private  payors,  the Company has been
restructuring its operations to enable IHS to focus on obtaining  contracts with
managed care organizations and to provide capitated  services.  IHS' strategy is
to become a preferred  or  exclusive  provider of  post-acute  care  services to
managed care organizations and other payors.

     In  implementing  its post-acute  care network  strategy,  IHS has recently
focused  on  expanding  its  home  healthcare  services  to  take  advantage  of
healthcare  payors'  increasing  focus  on  having  healthcare  provided  in the
lowest-cost  setting possible,  recent advances in medical technology which have
facilitated the delivery of medical services in alternative  sites and patients'
desires to be treated at home.  Consistent with the Company's  strategy,  IHS in
October  1996  acquired  First  American  Health Care of Georgia,  Inc.  ("First
American"), a provider of home health services,  principally home nursing, in 21
states, primarily Alabama, California,  Florida, Georgia, Michigan, Pennsylvania
and  Tennessee.   IHS  in  October  1997  acquired  RoTech  Medical  Corporation
("RoTech"),  a  provider  of home  healthcare  products  and  services,  with an
emphasis on home  respiratory,  home medical  equipment  and  infusion  therapy,
principally  to patients  in  non-urban  areas (the  "RoTech  Acquisition").  In
October 1997, IHS also acquired the lithotripsy division (the "Coram Lithotripsy
Division") of Coram Healthcare Corporation ("Coram"), which provided lithotripsy
services and equipment  maintenance  in 180 locations in 18 states,  in order to
expand the mobile  diagnostic  treatment  and  services  it offers to  patients,
payors  and  other  providers.  Lithotripsy  is a  non-invasive  technique  that
utilizes shock waves to disintegrate  kidney stones. IHS intends to use the home
healthcare  setting and the delivery franchise of the home healthcare branch and
agency network to (i) deliver  sophisticated care, such as skilled nursing care,
home  respiratory  therapy and  rehabilitation,  outside the hospital or nursing
home;  (ii) serve as an entry point for patients  into the IHS  post-acute  care
network; and (iii) provide a cost-effective site for case management and patient
direction.

     IHS has also continued to expand its post-acute  care network by increasing
the number of facilities it operates or manages. In September 1997, IHS acquired
Community Care of America,  Inc.  ("CCA"),  which develops and operates  skilled
nursing facilities in medically underserved rural communities (the

                                       6

"CCA  Acquisition").  IHS  believes  that CCA will broaden its  post-acute  care
network to include more rural markets and will complement its existing home care
locations  in rural  markets  as well as  RoTech's  business.  In  addition,  in
December 1997, IHS acquired from  HEALTHSOUTH  Corporation  ("HEALTHSOUTH")  139
owned,  leased or managed long-term care facilities and 12 specialty  hospitals,
as well as a  contract  therapy  business  having  over 1,000  contracts  and an
institutional pharmacy business serving approximately 38,000 beds (the "Facility
Acquisition").

     The  Company  provides   subacute  care  through  medical  specialty  units
("MSUs"),  which  are  typically  20 to 75 bed  specialty  units  with  physical
identities,   specialized  medical  technology  and  staffs  separate  from  the
geriatric  care  facilities  in which they are  located.  MSUs are  designed  to
provide comprehensive medical services to patients who have been discharged from
acute  care  hospitals  but  who  still  require  subacute  or  complex  medical
treatment.  The levels and quality of care  provided in the  Company's  MSUs are
similar to those provided in the hospital but at per diem treatment  costs which
IHS believes are  generally 30% to 60% below the cost of such care in acute care
hospitals. Because of the high level of specialized care provided, the Company's
MSUs generate  substantially higher net revenue and operating profit per patient
day than traditional geriatric care services.

     IHS presently  operates 313 geriatric care  facilities (258 owned or leased
and 55 managed),  excluding 13 facilities acquired in the CCA Acquisition and 42
facilities  acquired in the Facility  Acquisition which are being held for sale,
and 158 MSUs located within 84 of these  facilities.  Specialty medical services
revenues,   which   include  all  MSU  charges,   all  revenue  from   providing
rehabilitative therapies, pharmaceuticals,  medical supplies and durable medical
equipment to all its patients, all revenue from its Alzheimer's programs and all
revenue from its provision of pharmacy, rehabilitation therapy, home healthcare,
hospice care and similar services to  third-parties,  constituted  approximately
65%, 70% and 79% of net revenues  during the years ended December 31, 1995, 1996
and 1997,  respectively,  and 79% and 72% of net  revenues  in the three  months
ended  March 31,  1997 and 1998,  respectively.  IHS also offers a wide range of
basic  medical  services  as  well  as a  comprehensive  array  of  respiratory,
physical, speech,  occupational and physiatric therapy in all its geriatric care
facilities.  For the year ended  December  31, 1997 and the three  months  ended
March 31, 1998,  approximately 35% and 31%, respectively,  of IHS' revenues were
derived  from  home  health  and  hospice  care,   approximately  44%  and  41%,
respectively,   were  derived  from  subacute  and  other  ancillary   services,
approximately  19% and 28%,  respectively,  were derived from traditional  basic
nursing home services,  and approximately 2% and 1%, respectively,  were derived
from management and other services.  On a pro forma basis after giving effect to
the  acquisitions  consummated  by IHS in 1997,  for the year ended December 31,
1997,  approximately  30% of IHS'  revenues  were  derived  from home health and
hospice care,  approximately  43% were derived from subacute and other ancillary
services,  approximately  26% were derived from  traditional  basic nursing home
services and the remaining  approximately  1% were derived from  management  and
other services.

     Integrated  Health  Services,  Inc.  was  incorporated  in March  1986 as a
Pennsylvania  corporation and reorganized as a Delaware  corporation in November
1986. IHS' principal  executive  offices are located at 10065 Red Run Boulevard,
Owings Mills, Maryland 21117 and its telephone number is (410) 998-8400.  Unless
the  context  indicates  otherwise,  the terms "IHS" and the  "Company"  include
Integrated Health Services, Inc. and its subsidiaries.

                                 RISK FACTORS

     In addition to the other  information  in this  Prospectus,  the  following
factors  should be  considered  carefully  in  evaluating  the  Company  and its
business  before  purchasing  the shares of Common Stock  offered  hereby.  This
Prospectus  contains,  in addition to  historical  information,  forward-looking
statements that involve risks and  uncertainties.  The Company's  actual results
could  differ  materially.  Factors  that  could  cause  or  contribute  to such
differences  include,  but are not limited to, those discussed below, as well as
those  discussed   elsewhere  in  this   Prospectus   (including  the  documents
incorporated by reference herein).

     Risks Related to Substantial  Indebtedness.  The Company's  indebtedness is
substantial in relation to its  stockholders'  equity.  At March 31, 1998,  IHS'
total  long-term debt,  including  current  portion,  accounted for 73.3% of its
total  capitalization  (70.8% on a pro forma  basis after  giving  effect to the
redemption of the  Debentures  and the issuance of Common Stock upon  conversion
thereof  or  pursuant  to the  standby  arrangement  with  the  Purchaser).  See
"Capitalization." IHS also has significant lease obligations with respect to the
facilities operated pursuant to long-term leases, which aggregated approximately
$684.0  million at March 31, 1998.  For the year ended December 31, 1997 and the
three months ended March 31, 1998 the Company's  rent expense was $105.1 million
($163.7  million on a pro forma basis after  giving  effect to the  acquisitions
consummated by IHS in 1997) and $35.4 million, respectively. In addition, IHS is
obligated to pay an  additional  $155 million in respect of the  acquisition  of
First American  during 2000 to 2004, of which $115.2 million  (representing  the
present  value  thereof)  has been  recorded at March 31,  1998.  The  Company's
strategy of  expanding  its  specialty  medical  services  and  growing  through
acquisitions  may  require  additional  borrowings  in order to finance  working
capital,  capital  expenditures and the purchase price of any acquisitions.  The
degree to which the Company is  leveraged,  as well as its rent  expense,  could
have important consequences to securityholders,  including:  (i) IHS' ability to
obtain  additional  financing  in  the  future  for  working  capital,   capital
expenditures, acquisitions or general corporate purposes may be impaired, (ii) a
substantial  portion of IHS' cash flow from  operations  may be dedicated to the
payment of principal and interest on its indebtedness and rent expense,  thereby
reducing the funds  available to IHS for its  operations,  (iii) certain of IHS'
borrowings  bear, and will continue to bear,  variable rates of interest,  which
expose IHS to increases in interest rates, and (iv) certain of IHS' indebtedness
contains financial and other restrictive covenants,  including those restricting
the incurrence of additional indebtedness, the creation of liens, the payment of
dividends and sales of assets and imposing  minimum net worth  requirements.  In
addition,  IHS'  leverage may also  adversely  affect IHS' ability to respond to
changing business and economic conditions or continue its growth strategy. There
can be no  assurance  that IHS'  operating  results will be  sufficient  for the
payment of IHS' indebtedness.  If IHS were unable to meet interest, principal or
lease payments,  or satisfy  financial  covenants,  it could be required to seek
renegotiation of such payments and/or covenants or obtain  additional  equity or
debt financing. If additional funds are raised by issuing equity securities, the
Company's stockholders may experience dilution.  Further, such equity securities
may have rights,  preferences or privileges senior to those of the Common Stock.
To the extent IHS finances its activities with  additional  debt, IHS may become
subject to certain  additional  financial and other  covenants that may restrict
its ability to pursue its growth  strategy  and to pay  dividends  on the Common
Stock.  There can be no assurance  that any such efforts  would be successful or
timely  or that  the  terms  of any  such  financing  or  refinancing  would  be
acceptable to IHS. See "-- Risks Related to Capital Requirements." 

     In connection  with IHS' offering of its 9 1/4% Senior  Subordinated  Notes
due 2008 in September 1997 (the "9 1/4% Senior Notes"), Standard & Poors ("S&P")
confirmed its B rating of IHS' other  subordinated debt obligations,  but with a
negative  outlook,  and assigned the same rating to the 9 1/4% Senior Notes.  In
November  1997,  S&P placed the Company's  senior credit and  subordinated  debt
ratings on CreditWatch with negative  implications due to the proposed  Facility
Acquisition  and in January 1998 S&P downgraded  IHS' corporate  credit and bank
loan  ratings to B+ and its  subordinated  debt ratings to B- as a result of the
Facility Acquisition.  S&P stated that the speculative grade ratings reflect the
Company's high debt leverage and aggressive acquisition strategy,  uncertainties
with respect to future  government  efforts to control Medicare and Medicaid and
the unknown impact on IHS of recent changes in healthcare  regulation  providing
for a prospective payment system for both nursing homes and home healthcare. S&P
noted IHS'  outlook was stable.  In  connection  with the offering of the 9 1/4%
Senior  Notes,  Moody's  Investors  Service  ("Moody's")  downgraded  to B2  the
Company's other senior

                                       8


subordinated  debt  obligations,  but noted that the  outlook for the rating was
stable,  and assigned the new rating to the 9 1/4% Senior Notes.  Moody's stated
that the rating action reflects  Moody's  concern about the Company's  continued
rapid  growth  through  acquisitions,  which has  resulted in negative  tangible
equity of $114 million, making no adjustment for the $259 million of convertible
debt of IHS outstanding.  Moody's also stated that the availability  provided by
the Company's  new credit  facility and the 9 1/4% Senior Notes  positioned  the
Company to complete sizable acquisition  transactions using solely debt. Moody's
further  noted  that the rating  reflects  that  there are  significant  changes
underway in the  reimbursement  of services  rendered by IHS, and that the exact
impact of these changes is uncertain.

     Risks Associated with Growth Through Acquisitions and Internal Development.
IHS'  growth  strategy   involves  growth  through   acquisitions  and  internal
development  and, as a result,  IHS is subject to various risks  associated with
this growth strategy.  The Company's  planned  expansion and growth require that
the Company  expand its home  healthcare  services  through the  acquisition  of
additional home healthcare  providers and that the Company acquire, or establish
relationships  with,  third parties which provide  post-acute  care services not
currently provided by the Company and that the Company acquire, lease or acquire
the right to manage for others additional facilities.  Such expansion and growth
will depend on the Company's  ability to create demand for its  post-acute  care
programs,  the  availability  of  suitable  acquisition,   lease  or  management
candidates and the Company's  ability to finance such  acquisitions  and growth.
The successful  implementation of the Company's  post-acute  healthcare  system,
including  the  capitation  of rates,  will depend on the  Company's  ability to
expand the amount of post-acute care services it offers directly to its patients
rather  than  through  third-party  providers.  There can be no  assurance  that
suitable  acquisition  candidates  will be  located,  that  acquisitions  can be
consummated,   that  acquired  facilities  and  companies  can  be  successfully
integrated  into the  Company's  operations,  or that the  Company's  post-acute
healthcare  system,  including  the  capitation  of rates,  can be  successfully
implemented.  The post-acute care market is highly competitive,  and the Company
faces   substantial   competition  from  hospitals,   subacute  care  providers,
rehabilitation  providers and home healthcare  providers,  including competition
for  acquisitions.  The Company  anticipates  that  competition  for acquisition
opportunities will intensify due to the ongoing  consolidation in the healthcare
industry. See "-- Risks Related to Managed Care Strategy" and "-- Competition."

     The  successful   integration  of  acquired  businesses,   including  First
American,  RoTech,  CCA, the Coram  Lithotripsy  Division and the facilities and
other businesses acquired from HEALTHSOUTH, is important to the Company's future
financial  performance.  The anticipated benefits from any of these acquisitions
may not be  achieved  unless  the  operations  of the  acquired  businesses  are
successfully  combined  with  those  of the  Company  in a  timely  manner.  The
integration  of the  Company's  recent  acquisitions  will  require  substantial
attention from management. The diversion of the attention of management, and any
difficulties  encountered  in the  transition  process,  could  have a  material
adverse effect on the Company's  operations and financial results.  In addition,
the process of integrating the various  businesses  could cause the interruption
of, or a loss of momentum in, the activities of some or all of these businesses,
which  could have a material  adverse  effect on the  Company's  operations  and
financial  results.  There can be no assurance that the Company will realize any
of the anticipated  benefits from its  acquisitions.  The acquisition of service
companies that are not  profitable,  or the  acquisition of new facilities  that
result in significant integration costs and inefficiencies, could also adversely
affect the Company's profitability.

     IHS' current and anticipated future growth has placed, and will continue to
place,  significant  demands  on  the  management,   operational  and  financial
resources of IHS. The Company's  ability to manage its growth  effectively  will
require it to continue  to improve its  operational,  financial  and  management
information  systems and to continue to  attract,  train,  motivate,  manage and
retain key employees.  There can be no assurance that IHS will be able to manage
its  expanded  operations   effectively.   See  "--  Risks  Related  to  Capital
Requirements."

     There  can  be  no  assurance  that  the  Company  will  be  successful  in
implementing  its strategy or in responding to ongoing changes in the healthcare
industry  which  may  require  adjustments  to its  strategy.  If IHS  fails  to
implement its strategy successfully or does not respond timely and adequately to
ongoing changes in the healthcare  industry,  the Company's business,  financial
condition and results of operations will be materially adversely affected.

                                       9


     Risks Related to Managed Care Strategy. Managed care payors and traditional
indemnity insurers have experienced pressure from their policyholders to curb or
reduce  the  growth  in  premiums  paid to  such  organizations  for  healthcare
services.  This pressure has resulted in demands on healthcare service providers
to reduce  their  prices or to share in the  financial  risk of  providing  care
through  alternate fee structures such as capitation or fixed case rates.  Given
the increasing importance of managed care in the healthcare  marketplace and the
continued cost  containment  pressures from Medicare and Medicaid,  IHS has been
restructuring its operations to enable IHS to focus on obtaining  contracts with
managed  care  organizations  and to provide  capitated  services.  The  Company
believes that its home healthcare capabilities will be an important component of
its  ability  to  provide  services  under  capitated  and other  alternate  fee
arrangements.  However, to date there has been limited demand among managed care
organizations  for  post-acute  care  network  services,  and  there  can  be no
assurance that demand for such services will increase.  Further, IHS has limited
experience  in  providing  services  under  capitated  and other  alternate  fee
arrangements  and setting the  applicable  rates.  Accordingly,  there can be no
assurance  that  the  fees  received  by IHS will  cover  the  cost of  services
provided.  If  revenue  for  capitated  services  is  insufficient  to cover the
treatment  costs,  IHS'  operating  results  could be adversely  affected.  As a
result,  the success of IHS' managed care  strategy will depend in large part on
its ability to increase  demand for post-acute  care services among managed care
organizations,  to obtain favorable  agreements with managed care  organizations
and to manage  effectively  its operating and healthcare  delivery costs through
various methods,  including  utilization  management and competitive pricing for
purchased  services.  Additionally,  there  can  be no  assurance  that  pricing
pressures faced by healthcare  providers will not have a material adverse effect
on the Company's business, results of operations and financial condition. 

     Further,  pursuing a  strategy  focused on  risk-sharing  fee  arrangements
entails certain  regulatory risks. Many states impose  restrictions on a service
provider's  ability  to  provide  capitated  services  unless  it meets  certain
financial  criteria,  and may view  capitated fee  arrangements  as an insurance
activity,  subjecting the entity accepting the capitated fee to regulation as an
insurance company rather than merely a licensed  healthcare provider accepting a
business  risk in  connection  with the manner in which it is  charging  for its
services.  The laws  governing  risk-sharing  fee  arrangements  for  healthcare
service  providers  are  evolving  and are not  certain  at  this  time.  If the
risk-sharing  activities of IHS require licensure as an insurance company, there
can be no assurance  that IHS could obtain or maintain the necessary  licensure,
or that IHS would be able to meet any financial  criteria imposed by a state. If
the Company were  precluded  from  providing  services  under  risk-sharing  fee
arrangements,  its  managed  care  strategy  would be  adversely  affected.  See
"--Uncertainty of Government Regulation."

     Risks  Related to  Capital  Requirements.  IHS'  growth  strategy  requires
substantial  capital for the  acquisition  of  additional  home  healthcare  and
related  service   providers  and  geriatric  care  facilities.   The  effective
integration,  operation  and  expansion  of the  existing  businesses  will also
require  substantial  capital.  The Company expects to finance new  acquisitions
from a combination of funds from  operations,  borrowings  under its bank credit
facility  and the  issuance  of  debt  and  equity  securities.  IHS  may  raise
additional capital through the issuance of long-term or short-term  indebtedness
or  the  issuance  of  additional   equity   securities  in  private  or  public
transactions,  at such  times as  management  deems  appropriate  and the market
allows.  Any of such  financings  could  result in dilution  of existing  equity
positions,  increased  interest and amortization  expense or decreased income to
fund future expansion.  There can be no assurance that acceptable  financing for
future  acquisitions or for the integration and expansion of existing businesses
and operations can be obtained.  The Company's bank credit  facility  limits the
Company's  ability to make  acquisitions,  and certain of the  indentures  under
which the Company's  outstanding senior subordinated debt securities were issued
limit the Company's  ability to incur  additional  indebtedness  unless  certain
financial tests are met. See "-- Risks Related to Substantial Indebtedness."

     Risks Related to Recent  Acquisitions.  IHS has recently  completed several
major  acquisitions,  including the acquisitions of First American,  RoTech, CCA
and the Coram Lithotripsy Division and the Facility Acquisition, and is still in
the process of integrating those acquired businesses. The IHS Board of Directors
and senior  management of IHS face a  significant  challenge in their efforts to
integrate the acquired  businesses,  including First American,  RoTech, CCA, the
Coram Lithotripsy Division and the facilities and other businesses acquired from
HEALTHSOUTH.  The  dedication of management  resources to such  integration  may
detract attention from the day-to-day business of IHS. The difficulties of

                                       10


integration  may be increased by the  necessity of  coordinating  geographically
separated   organizations,   integrating   personnel  with  disparate   business
backgrounds  and  combining  different  corporate  cultures.  There  can  be  no
assurance  that  there  will  not be  substantial  costs  associated  with  such
activities  or that there will not be other  material  adverse  effects of these
integration  efforts.  Further,  there  can be no  assurance  that  management's
efforts to integrate the operations of IHS and newly acquired  companies will be
successful or that the anticipated  benefits of the recent  acquisitions will be
fully realized.

     IHS has recently  expanded  significantly  its home healthcare  operations.
During the years ended  December  31, 1996 and 1997 and the three  months  ended
March 31, 1997 and 1998,  home  healthcare  accounted for  approximately  16.3%,
35.4%,  33.8% and 30.2%,  respectively,  of IHS' total revenues.  On a pro forma
basis,  after giving effect to the acquisitions and divestitures  consummated by
IHS in 1996 and 1997,  home  healthcare  accounted for  approximately  28.8% and
29.6% of IHS'  total  revenues  in 1996 and 1997,  respectively.  On a pro forma
basis,  approximately  70.7%  and 73.0% of IHS' home  healthcare  revenues  were
derived  from  Medicare  in  the  years  ended   December  31,  1996  and  1997,
respectively.  On a pro forma basis, after giving effect to the acquisitions and
divestitures  consummated  by  IHS in  1996  and  1997,  home  nursing  services
accounted  for  approximately  64.2%  and  56.2%,  respectively,  of  IHS'  home
healthcare  revenues in these  periods.  Medicare  has  developed a national fee
schedule  for  infusion  therapy  and  home  medical  equipment  which  provides
reimbursement at 80% of the amount of any fee on the schedule. The remaining 20%
is  paid  by  other  third  party  payors  (including  Medicaid  in the  case of
"medically  indigent"  patients)  or  patients.  With  respect to home  nursing,
Medicare generally  reimburses for the cost of providing such services,  up to a
regionally adjusted allowable maximum per visit and per discipline with no fixed
limit on the number of visits prior to 1998. There generally is no deductible or
coinsurance. As a result, there is no reward for efficiency, provided that costs
are below the cap, and traditional home healthcare services carry relatively low
margins.  The Balanced  Budget Act of 1997 (the "BBA"),  enacted in August 1997,
provides  for a reduction in current  cost  reimbursement  for home nursing care
pending implementation of a prospective payment system for home nursing services
for cost reporting periods beginning on or after October 1, 1999. Implementation
of a  prospective  payment  system will be a critical  element to the success of
IHS'  expansion  into  home  nursing  services.  Based  upon  prior  legislative
proposals,  IHS believes  that a  prospective  payment  system would most likely
provide a healthcare  provider a  predetermined  rate for a given service,  with
providers  that have costs below the  predetermined  rate being entitled to keep
some or all of this  difference.  There can be no assurance  that  Medicare will
implement a  prospective  payment  system for home nursing  services in the next
several  years or at all. The  implementation  of a prospective  payment  system
requires  IHS  to  make  contingent  payments  related  to  the  First  American
Acquisition  of $155  million over a period of five years.  Until a  prospective
payment system for home nursing  services is introduced,  IHS  anticipates  that
margins for home nursing will remain low and may adversely  impact its financial
performance.  IHS is currently  exploring  ways to reduce the impact of its home
nursing business on its financial performance, which may include a "spin-off" of
such  operations.  In addition,  the BBA reduces the Medicare  national  payment
limits for oxygen and oxygen equipment used in home  respiratory  therapy by 25%
in  1998  and  30%  (from  1997  levels)  in  1999  and  each  subsequent  year.
Approximately  50% of RoTech's  total  revenues  for 1997 were  derived from the
provision  of oxygen  services to Medicare  patients.  The  inability  of IHS to
realize  operating  efficiencies and provide home healthcare  services at a cost
below the established Medicare fee schedule could have a material adverse effect
on IHS' home healthcare operations and its post-acute care network. See "-- Risk
of Adverse Effect of Healthcare Reform."

     Reliance on  Reimbursement  by Third  Party  Payors.  The Company  receives
payment for services  rendered to patients  from  private  insurers and patients
themselves,  from the Federal government under Medicare,  and from the states in
which it operates  under  Medicaid.  The healthcare  industry is  experiencing a
trend toward cost  containment,  as government and other third party payors seek
to impose  lower  reimbursement  and  utilization  rates and  negotiate  reduced
payment  schedules  with service  providers.  These cost  containment  measures,
combined with the  increasing  influence of managed care payors and  competition
for  patients,  has  resulted in reduced  rates of  reimbursement  for  services
provided by IHS,  which has  adversely  affected,  and may continue to adversely
affect,  IHS'  margins,   particularly  in  its  skilled  nursing  and  subacute
facilities.  Aspects of certain healthcare reform proposals, such as cutbacks in
the Medicare and Medicaid programs,  reductions in Medicare  reimbursement rates
and/or limitations

                                       11

on reimbursement  rate increases,  containment of healthcare costs on an interim
basis by means  that  could  include a  short-term  freeze on prices  charged by
healthcare   providers,   and  permitting   greater  state  flexibility  in  the
administration of Medicaid,  could adversely affect the Company. There can be no
assurance that adequate  reimbursement  levels will continue to be available for
services to be provided by IHS which are currently being reimbursed by Medicare,
Medicaid  or  private  payors.  Significant  limits  on the  scope  of  services
reimbursed  and on  reimbursement  rates and fees could have a material  adverse
effect on the Company's results of operations and financial  condition.  See "--
Risk of Adverse  Effect of Healthcare  Reform."  During the years ended December
31, 1995,  1996 and 1997 and the three months ended March 31, 1997 and 1998, the
Company derived approximately 55%, 60%, 66%, 67% and 63%,  respectively,  of its
patient  revenues from Medicare and Medicaid.  On a pro forma basis after giving
effect to the acquisitions and divestitures consummated by IHS in 1996 and 1997,
approximately  69% of the  Company's  patient  revenues  have been  derived from
Medicare and Medicaid in each of the years ended December 31, 1996 and 1997.

     The sources and amounts of the Company's  patient revenues derived from the
operation of its geriatric care  facilities and MSU programs are determined by a
number of factors, including licensed bed capacity of its facilities,  occupancy
rate, the mix of patients and the rates of reimbursement  among payor categories
(private,  Medicare and Medicaid).  Changes in the mix of the Company's patients
among the private pay, Medicare and Medicaid categories can significantly affect
the  profitability of the Company's  operations.  The Company's cost of care for
its MSU patients  generally exceeds regional  reimbursement  limits  established
under Medicare. The success of the Company's MSU strategy will depend in part on
its  ability  to obtain  per diem rate  approvals  for costs  which  exceed  the
Medicare  established  per diem rate  limits and by  obtaining  waivers of these
limitations.  There can be no assurance  that the Company will be able to obtain
the waivers necessary to enable the Company to recover its excess costs.

     Managed care  organizations  and other third party payors have continued to
consolidate  to enhance  their  ability to influence  the delivery of healthcare
services. Consequently, the healthcare needs of a large percentage of the United
States  population are provided by a small number of managed care  organizations
and third  party  payors.  These  organizations  generally  enter  into  service
agreements with a limited number of providers for needed services. To the extent
such  organizations  terminate  IHS as a preferred  provider  and/or engage IHS'
competitors as a preferred or exclusive  provider,  the business of IHS could be
materially adversely affected.

     Risk of Adverse  Effect of  Healthcare  Reform.  In addition  to  extensive
existing government healthcare regulation, there are numerous initiatives on the
federal and state levels for comprehensive reforms affecting the payment for and
availability of healthcare services,  including a number of proposals that would
significantly limit  reimbursement under Medicare and Medicaid.  It is not clear
at this time what proposals, if any, will be adopted or, if adopted, what effect
such proposals would have on the Company's business. Aspects of certain of these
healthcare  proposals,  such as cutbacks in the Medicare and Medicaid  programs,
containment of healthcare  costs on an interim basis by means that could include
a short-term  freeze on prices charged by healthcare  providers,  and permitting
greater state  flexibility in the  administration  of Medicaid,  could adversely
affect  the  Company.  IHS  expects  that  there will  continue  to be  numerous
initiatives on the federal and state levels for comprehensive  reforms affecting
the payment for and  availability of healthcare  services,  including  proposals
that will further limit  reimbursement  under  Medicare and Medicaid.  It is not
clear at this time what proposals,  if any, will be adopted or, if adopted, what
effect  such  proposals  will have on IHS'  business.  See "-- Risks  Related to
Recent  Acquisitions"  and "-- Reliance on Reimbursement by Third Party Payors."
There  can  be  no  assurance  that  currently  proposed  or  future  healthcare
legislation  or  other  changes  in  the  administration  or  interpretation  of
governmental  healthcare programs will not have an adverse effect on the Company
or that payments under governmental programs will remain at levels comparable to
present  levels or will be sufficient  to cover the costs  allocable to patients
eligible  for  reimbursement  pursuant  to  such  programs.  Concern  about  the
potential  effects  of the  proposed  reform  measures  has  contributed  to the
volatility  of prices of  securities  of  companies  in  healthcare  and related
industries,  including the Company,  and may  similarly  affect the price of the
Company's   securities  in  the  future.   See   "--Uncertainty   of  Government
Regulation."
 
                                       12


     The BBA provides,  among other things, for a prospective payment system for
skilled  nursing  facilities  to  be  implemented  for  cost  reporting  periods
beginning  on or after  July 1,  1998,  a  prospective  payment  system for home
nursing to be  implemented  for cost  reporting  periods  beginning  on or after
October 1, 1999, a reduction in current cost reimbursement for home nursing care
pending  implementation of a prospective payment system,  reductions  (effective
January 1, 1998) in Medicare  reimbursement  for oxygen and oxygen equipment for
home  respiratory  therapy and a shift of the bulk of home health  coverage from
Part A to Part B of Medicare.  The BBA also instituted  consolidated billing for
skilled nursing facility services, under which payments for non-physician Part B
services  for  beneficiaries  no  longer  eligible  for Part A  skilled  nursing
facility  care will be made to the  facility,  regardless of whether the item or
service was furnished by the facility,  by others under arrangement or under any
other  contracting  or consulting  arrangement,  effective for items or services
furnished on or after July 1, 1997.  With  respect to Medicaid,  the BBA repeals
the  so-called  Boren  Amendment,  which  required  state  Medicaid  programs to
reimburse nursing  facilities for the costs that are incurred by efficiently and
economically  operated  providers in order to meet quality and safety standards.
As a result,  states now have considerable  flexibility in establishing  payment
rates.  The inability of IHS to provide home  healthcare  and/or skilled nursing
services at a cost below the  established  Medicare  fee  schedule  could have a
material  adverse effect on IHS' home  healthcare  operations,  post-acute  care
network and business generally.

     Under the new  prospective  payment  system for Medicare  reimbursement  to
skilled nursing facilities, facilities will receive a pre-established daily rate
for each individual Medicare  beneficiary being cared for, based on the activity
level of the  patient.  The  pre-established  daily rate will cover all routine,
ancillary and capital costs.  It is anticipated  that this  prospective  payment
system   will  be  phased  in  over  four  years  on  a  blended   rate  of  the
facility-specific costs and the new federal per diem, which has not to date been
established.  The blended rate for the first year of transition will take 75% of
the  facility-specific  per diem rate and 25% of the federal  per diem rate.  In
each subsequent  transition year, the  facility-specific per diem rate component
will  decrease by 25% and the federal per diem rate  component  will increase by
25%,  ultimately  resulting in a rate based 100% upon the federal per diem.  The
facility-specific  per diem rate is based upon the  facility's  1995 cost report
for routine,  ancillary and capital  services,  updated using a skilled  nursing
market basket index.  The federal per diem is calculated by the weighted average
of each  facility's  standardized  costs,  based  upon the  historical  national
average per diem for freestanding facilities. Prospective payment for IHS' owned
and leased skilled  nursing  facilities will be effective  beginning  January 1,
1999 for all  facilities  other than the facilities  acquired from  HEALTHSOUTH,
which will become  subject to prospective  payment on June 1, 1999.  Prospective
payment for skilled nursing facilities managed by IHS will be effective for each
facility at the  beginning of its first cost  reporting  period  beginning on or
after July 1, 1998. The new prospective payment system will also cover ancillary
services provided to patients at skilled nursing facilities.

     IHS anticipates  that the prospective  payment system for home nursing will
provide  for  prospectively  established  per visit  payments to be made for all
covered services,  which will then be subject to an annual aggregate per episode
limit at the end of the year.  Home health  agencies that are able to keep their
total  expenses per visit during the year below their per episode  annual limits
will be able to retain a  specified  percentage  of the  difference,  subject to
certain aggregate limitations. Such changes could have a material adverse effect
on the Company and its growth  strategy.  The  implementation  of a  prospective
payment system requires the Company to make contingent  payments  related to the
acquisition of First  American of $155 million over a period of five years.  The
failure to implement a prospective  payment system for home nursing  services in
the next  several  years could  adversely  affect IHS'  postacute  care  network
strategy. See "-- Risks Related to Recent Acquisitions."

     Uncertainty  of  Government  Regulation.  The  Company  and the  healthcare
industry generally are subject to extensive federal,  state and local regulation
governing   licensure  and  conduct  of   operations  at  existing   facilities,
construction of new facilities, acquisition of existing facilities, additions of
new services, certain capital expenditures, the quality of services provided and
the manner in which such  services are provided and  reimbursement  for services
rendered.  Changes in applicable laws and regulations or new  interpretations of
existing laws and regulations could have a material adverse effect on licensure,
eligibility for participation,  permissible activities,  operating costs and the
levels of reimbursement from

                                       13


governmental  and other  sources.  There  can be no  assurance  that  regulatory
authorities  will  not  adopt  changes  or  new   interpretations   of  existing
regulations that could adversely affect the Company.  The failure to maintain or
renew any required  regulatory  approvals or licenses  could prevent the Company
from offering  existing  services or from  obtaining  reimbursement.  In certain
circumstances,  failure to comply at one  facility may affect the ability of the
Company to obtain or maintain  licenses or approvals under Medicare and Medicaid
programs at other  facilities.  In addition,  in the conduct of its business the
Company's  operations  are  subject  to review by federal  and state  regulatory
agencies to assure continued compliance with various standards,  their continued
licensing  under  state  law and their  certification  under  the  Medicare  and
Medicaid  programs.  In the course of these  reviews,  problems are from time to
time identified by these agencies.  The Company has to date been able to resolve
these problems in a manner  satisfactory  to the regulatory  agencies  without a
material  adverse effect on its business,  and the Company believes that it will
be  able  to  resolve  all  current  reviews  in a  manner  satisfactory  to the
regulatory agencies without a material adverse effect on its business.  However,
there can be no assurance  that IHS will be able to  satisfactorily  resolve all
current or future reviews.

     In 1995 the  Health  Care  Financing  Administration  ("HCFA")  implemented
stricter  guidelines for annual state surveys of long-term  care  facilities and
expanded remedies available to enforce compliance with the detailed  regulations
mandating  minimum  healthcare  standards.  Remedies  include fines, new patient
admission moratoriums,  denial of reimbursement,  federal or state monitoring of
operations,  closure of facilities  and  termination  of provider  reimbursement
agreements.  These  provisions  eliminate the ability of operators to appeal the
scope and severity of any  deficiencies and grant state regulators the authority
to impose new remedies,  including  monetary  penalties,  denial of payments and
termination  of the  right  to  participate  in  the  Medicare  and/or  Medicaid
programs. The Company believes these new guidelines may result in an increase in
the number of facilities that will not be in "substantial  compliance"  with the
regulations  and, as a result,  subject to  increased  disciplinary  actions and
remedies,  including admission holds and termination of the right to participate
in the Medicare and/or Medicaid programs. In ranking facilities,  survey results
subsequent  to  October  1990  are  considered.   As  a  result,  the  Company's
acquisition of poorly performing facilities could adversely affect the Company's
business to the extent remedies are imposed at such facilities.

     In September 1997, President Clinton, in an attempt to curb Medicare fraud,
imposed a moratorium on the certification  under Medicare of new home healthcare
companies,  which  moratorium  expired in January 1998,  and  implemented  rules
requiring home healthcare providers to reapply for Medicare  certification every
three years. In addition, HCFA will double the number of detailed audits of home
healthcare  providers it  completes  each year and increase by 25% the number of
home healthcare  claims it reviews each year. IHS cannot predict what effect, if
any,  these new rules will have on IHS'  business and the  expansion of its home
healthcare operations.

     Federal and state regulatory and law enforcement  authorities have recently
expanded the scope of enforcement  activities with respect to laws applicable to
the Company's  business,  including  with respect to Medicare and Medicaid fraud
and abuse regulations,  other reimbursement laws and laws relating to quality of
patient  care.  In addition,  media  attention  to  enforcement  activities  has
recently  increased.  There  can  be no  assurance  that  any  such  enforcement
activities  with  respect to the Company or its  competitors,  or any  resultant
media  attention  given to such matters,  will not directly or indirectly have a
material adverse effect on the Company's business,  financial condition, results
of operations or the market price of the Common Stock. 

     The  Company  is also  subject  to  federal  and state  laws  which  govern
financial and other arrangements between healthcare providers.  These laws often
prohibit  certain  direct and indirect  payments or  fee-splitting  arrangements
between  healthcare  providers  that are  designed  to induce or  encourage  the
referral of patients to, or the  recommendation  of, a  particular  provider for
medical  products and  services.  These laws include the federal  "Stark  Acts,"
which  prohibit,  with  limited  exceptions,   financial  relationships  between
ancillary   service  providers  and  referring   physicians,   and  the  federal
"anti-kickback  law," which prohibits,  among other things, the offer,  payment,
solicitation  or receipt of any form of  remuneration in return for the referral
of  Medicare  and  Medicaid  patients.  The Office of  Inspector  General of the
Department  of Health and Human  Services,  the  Department of Justice and other
federal

                                       14

agencies  interpret these fraud and abuse provisions  liberally and enforce them
aggressively.  The BBA contains new civil  monetary  penalties for violations of
these laws and imposes an  affirmative  duty on providers to insure that they do
not employ or contract with persons excluded from the Medicare program.  The BBA
also  provides a minimum 10 year  period for  exclusion  from  participation  in
Federal  healthcare   programs  of  persons  convicted  of  a  prior  healthcare
violation.  In addition,  some states restrict  certain  business  relationships
between  physicians  and other  providers of  healthcare  services.  Many states
prohibit business  corporations from providing,  or holding  themselves out as a
provider of,  medical  care.  Possible  sanctions  for violation of any of these
restrictions  or  prohibitions  include  loss of  licensure  or  eligibility  to
participate in reimbursement  programs (including Medicare and Medicaid),  asset
forfeitures  and civil and  criminal  penalties.  These  laws vary from state to
state,  are often  vague  and have  seldom  been  interpreted  by the  courts or
regulatory agencies. The Company seeks to structure its business arrangements in
compliance  with  these  laws and,  from time to time,  the  Company  has sought
guidance  as to the  interpretation  of  such  laws;  however,  there  can be no
assurance that such laws ultimately  will be interpreted in a manner  consistent
with the practices of the Company.

     Many  states  have  adopted  certificate  of need  or  similar  laws  which
generally require that the appropriate state agency approve certain acquisitions
or capital  expenditures  in excess of defined  levels and determine that a need
exists for certain new bed additions,  new services and the  acquisition of such
medical equipment or capital  expenditures or other changes prior to beds and/or
services  being  added.  Many  states  have  placed  a  moratorium  on  granting
additional  certificates  of need or otherwise  stated their intent not to grant
approval  for new beds.  To the  extent  certificates  of need or other  similar
approvals are required for expansion of the Company's operations, either through
facility  acquisitions  or  expansion  or  provision  of new  services  or other
changes,  such expansion could be adversely affected by the failure or inability
to obtain the necessary  approvals,  changes in the standards applicable to such
approvals and possible delays in, and the expenses  associated  with,  obtaining
such approvals.

     The  Company is unable to predict the future  course of  federal,  state or
local regulation or legislation,  including  Medicare and Medicaid  statutes and
regulations.  Further changes in the regulatory  framework could have a material
adverse  effect on the Company's  business,  results of operations and financial
condition. See "-- Risk of Adverse Effect of Healthcare Reform."

     Competition.  The healthcare  industry is highly competitive and is subject
to  continuing  changes in the  provision  of  services  and the  selection  and
compensation  of providers.  The Company  competes on a local and regional basis
with other  providers  on the basis of the breadth and quality of its  services,
the quality of its facilities and, to a more limited extent,  price. The Company
also  competes  with other  providers  in the  acquisition  and  development  of
additional facilities and service providers. The Company's current and potential
competitors  include  national,  regional and local  operators of geriatric care
facilities,  acute care hospitals and  rehabilitation  hospitals,  extended care
centers,  retirement  centers and  community  home health  agencies,  other home
healthcare companies and similar institutions,  many of which have significantly
greater financial and other resources than the Company. In addition, the Company
competes with a number of tax-exempt  nonprofit  organizations which can finance
acquisitions  and  capital   expenditures  on  a  tax-exempt  basis  or  receive
charitable  contributions  unavailable to the Company. New service introductions
and  enhancements,   acquisitions,  continued  industry  consolidation  and  the
development  of  strategic  relationships  by  IHS'  competitors  could  cause a
significant  decline in sales or loss of market  acceptance  of IHS' services or
intense  price  competition  or  make  IHS'  services  noncompetitive.  Further,
technological  advances  in drug  delivery  systems and the  development  of new
medical  treatments  that cure certain  complex  diseases or reduce the need for
healthcare  services could adversely impact the business of IHS. There can be no
assurance  that IHS will be able to  compete  successfully  against  current  or
future  competitors  or that  competitive  pressures  will not  have a  material
adverse effect on IHS' business,  financial condition and results of operations.
IHS also competes with various  healthcare  providers with respect to attracting
and retaining qualified management and other personnel.  Any significant failure
by IHS to attract and retain  qualified  employees could have a material adverse
effect on its business, results of operations and financial condition.

     Effect of Certain Anti-Takeover Provisions. IHS' Third Restated Certificate
of Incorporation  and By-laws,  as well as the Delaware General  Corporation Law
(the "DGCL"), contain certain provisions that could have the effect of making it
more difficult for a third party to acquire, or discouraging a third

                                       15

party from attempting to acquire,  control of IHS. These  provisions could limit
the price  that  certain  investors  might be  willing  to pay in the future for
shares of Common Stock.  Certain of these provisions allow IHS to issue, without
stockholder  approval,  preferred  stock having voting rights senior to those of
the  Common  Stock.   Other  provisions  impose  various  procedural  and  other
requirements  that  could  make it more  difficult  for  stockholders  to effect
certain corporate actions. In addition, the IHS Stockholders' Rights Plan, which
provides  for  discount  purchase  rights to  certain  stockholders  of IHS upon
certain  acquisitions of 20% or more of the outstanding  shares of Common Stock,
may also inhibit a change in control of IHS. As a Delaware  corporation,  IHS is
subject to Section 203 of the DGCL,  which, in general,  prevents an "interested
stockholder"  (defined  generally  as  a  person  owning  15%  or  more  of  the
corporation's   outstanding   voting   stock)  from   engaging  in  a  "business
combination"  (as defined) for three years following the date such person became
an  interested   stockholder  unless  certain  conditions  are  satisfied.   See
"Description of Capital Stock -- Stockholders' Rights Plan."

     Possible Volatility of Stock Price. There may be significant  volatility in
the  market  price of the  Common  Stock.  Quarterly  operating  results of IHS,
changes in general  conditions  in the  economy,  the  financial  markets or the
healthcare  industry,  or other  developments  affecting IHS or its competitors,
could cause the market price of the Common Stock to fluctuate substantially.  In
addition,  in recent years the stock market and, in  particular,  the healthcare
industry segment,  has experienced  significant  price and volume  fluctuations.
This  volatility  has  affected the market  price of  securities  issued by many
companies for reasons  unrelated to their  operating  performance.  In the past,
following  periods of volatility in the market price of a company's  securities,
securities  class  action  litigation  has often  been  initiated  against  such
company.  Such litigation  could result in substantial  costs and a diversion of
management's attention and resources, which could have a material adverse effect
upon IHS' business, operating results and financial condition.


                              RECENT DEVELOPMENTS

     In March 1998 the Company  sold five  long-term  care  facilities  to Omega
Healthcare Investors,  Inc. ("Omega"),  a publicly-traded real estate investment
trust,  for  approximately   $50.5  million.   Omega  immediately  leased  these
facilities to Lyric Health Care LLC ("Lyric") at an annual rent of approximately
$4.95 million. Lyric is a newly-formed company 50% owned by IHS and 50% owned by
TFN Healthcare  Investors,  Inc., an entity controlled by Timothy  Nicholson,  a
director of the Company.  The Company  manages these  facilities as well as five
other long-term care facilities which the Company sold to Omega and Omega leased
to Lyric in January 1998.  The Company  receives a base  management fee of 3% of
gross revenues, subject to increase if gross revenues exceed $350 million, and a
franchise  fee of 1% of gross  revenues.  The  management  agreement  with Lyric
provides  for an incentive  management  fee equal to 70% of annual net cash flow
(as defined in the management  agreement).  IHS did not recognize a gain or loss
on the sale.

     In April 1998 the Company  reached an  agreement  in  principle  to sell 44
facilities to Monarch  Properties,  Inc., a newly-formed  real estate investment
trust  ("Monarch"),  for an  aggregate  purchase  price  of  approximately  $371
million.  It is  currently  contemplated  that Monarch will lease 42 of these 44
facilities  to Lyric,  and that  Lyric  will  engage  the  Company to manage the
facilities  pursuant to the arrangements  described above. The transactions with
Monarch and Lyric are subject to  completion  of  definitive  documentation  and
completion of Monarch's  initial public offering,  and there can be no assurance
that the transaction  will be completed on these terms, on different terms or at
all. Dr. Robert N. Elkins,  the Company's Chairman of the Board, Chief Executive
Officer and President,  is Chairman of the Board of Directors of Monarch, and it
is currently  contemplated  that he will  beneficially  own between five and ten
percent of Monarch following completion of Monarch's public offering.

     In April  1998 IHS  acquired a company  that  operates  13 skilled  nursing
facilities  for  approximately  $15.9  million.  In April 1998, the Company also
purchased, for an aggregate of approximately $5.5 million, seven companies which
provide  respiratory  therapy  services.  In May 1998 the Company  acquired five
companies  which  provide  respiratory  therapy  services  for an  aggregate  of
approximately $15.1 million.

     The Company has reached agreements in principle to purchase a company which
operates 31 skilled  nursing  facilities  for  approximately  $53.2  million,  a
skilled nursing  facility for $4.7 million,  two  lithotripsy  operations for an
aggregate  of  approximately  $20.4  million and 18  respiratory  companies  for
approximately  $30.7  million.  There  can be no  assurance  that  any of  these
acquisitions will be consummated on these terms, on different terms or at all.

                                USE OF PROCEEDS

     The net proceeds,  if any,  received by the Company from the sale of Common
Stock to the  Purchaser  pursuant to the standby  arrangements  described  under
"Standby Arrangements" will be used to fund the redemption of any Debentures not
surrendered for conversion.  Any other amounts  received by the Company from the
Purchaser  pursuant  to the  standby  arrangements  will  be  used  for  general
corporate  purposes.  The amount of the  proceeds  to be received by the Company
from the Purchaser is not determinable at this time,  because neither the number
of shares,  if any, that will be sold to the Purchaser nor the amount of profit,
if any,  that the  Purchaser  may  realize  upon  resale of such  shares  can be
determined at this time. The Company will not receive any cash proceeds from the
issuance of Common Stock upon conversion of the Debentures.


                                 CAPITALIZATION

     The following table sets forth the  capitalization  of the Company at March
31, 1998 and as adjusted  to give  effect to the assumed  conversion  of all the
outstanding Debentures and the issuance of 3,579,766 shares of Common Stock, net

- ----------------
(1) The Company has grown substantially  through acquisitions and the opening of
    MSUs,   which   acquisitions   and  MSU  openings   materially   affect  the
    comparability of the financial data reflected herein. In addition,  IHS sold
    its  pharmacy  division in July 1996,  a majority  interest in its  assisted
    living  services  subsidiary  ("ILC")  in  October  1996  and the  remaining
    interest in ILC in July 1997 (the "ILC Sale").

(2) In 1995,  the Company merged with  IntegraCare,  Inc.  ("IntegraCare")  in a
    transaction  accounted  for as a  pooling  of  interests.  Accordingly,  the
    Company's  historical  financial  statements  for all  periods  prior to the
    effective  date of the merger  have been  restated to include the results of
    IntegraCare.

(3) In 1995,  consists of (i) expenses of $1,939,000  related to the merger with
    IntegraCare,  (ii) a $21,915,000 loss on the write-off of accrued management
    fees  ($8,496,000),  loans  ($11,097,000)  and contract  acquisi- tion costs
    ($2,322,000) related to the Company's termination of its agreement,  entered
    into in January 1994, to manage 23 long-term care and psychiatric facilities
    owned by Crestwood Hospital,  (iii) the write-off of $25,785,000 of deferred
    pre-opening costs resulting from a change in accounting  estimate  regarding
    the  future  benefit  of  deferred  pre-opening  costs  and  (iv) a loss  of
    $83,321,000  resulting from the Company's election in December 1995 of early
    implementation of SFAS No. 121,  Accounting for the Impairment of Long-Lived
    Assets  and for  Long-Lived  Assets to Be  Disposed  Of.  In 1996,  consists
    primarily  of (i) a gain  of  $34,298,000  from  the  sale  of its  pharmacy
    division,  (ii) a loss of $8,497,000 from its sale of shares in its assisted
    living services subsidiary,  (iii) a $7,825,000 loss on write-off of accrued
    management  fees and loans  resulting from the Company's  termination of its
    ten year  management  contract  with All  Seasons,  originally  entered into
    during  September  1994 and (iv) a $3,519,000  exit cost  resulting from the
    closure of redundant home  healthcare  agencies.  Because IHS' investment in
    the Capstone common stock received in the sale of its pharmacy  division had
    a very small tax basis, the taxable gain on the sale significantly  exceeded
    the  gain  for  financial  reporting   purposes,   thereby  resulting  in  a
    disproportionately higher income tax provision related to the sale. In 1997,
    consists  primarily  of (i) a gain of  $7,580,000  realized on the shares of
    Capstone  common stock received in the sale of its pharmacy  division in the
    first  quarter,  (ii) the write-off of $6,555,000 of  accounting,  legal and
    other costs resulting from the proposed merger transaction with Coram in the
    first quarter,  (iii) the payment to Coram of $21,000,000 in connection with
    the termination of the proposed merger  transaction with Coram,  (iv) a gain
    of $3,914,000  from the ILC Sale,  (v) a loss of $4,750,000  resulting  from
    termination  payments in connection  with the RoTech  Acquisition and (vi) a
    loss  of  $112,231,000  resulting  from  its  plan  to  dispose  of  certain
    non-strategic assets to allow the Company to focus on its core operations.

(4) In 1993, the Company recorded a loss on extinguishment of debt of $3,730,000
    relating  primarily to the write-off of deferred financing costs. Such loss,
    reduced by the related income tax effect of $1,455,000, is presented for the
    year ended  December 31, 1993 as an  extraordinary  loss of  $2,275,000.  In
    1994, the Company  recorded a loss on  extinguishment  of debt of $6,839,000
    relating  primarily to the write-off of deferred financing costs. Such loss,
    reduced by the related income tax effect of $2,565,000, is presented for the
    year ended  December 31, 1994 as an  extraordinary  loss of  $4,274,000.  In
    1995, the Company  recorded a loss on  extinguishment  of debt of $1,647,000
    relating  primarily  to  prepayment  charges and the  write-off  of deferred
    financing  costs.  Such loss,  reduced by the  related  income tax effect of
    $634,000,  is  presented  for  the  year  ended  December  31,  1995  as  an
    extraordinary  loss of $1,013,000.  In 1996, the Company  recorded a loss on
    extinguishment of debt of $2,327,000, relating primarily to the write-off of
    deferred  financing  costs.  Such loss,  reduced by the  related  income tax
    effect of $896,000, is presented in the statement of operations for the year
    ended December 31, 1996 as an extraordinary loss of $1,431,000. In 1997, IHS
    recorded  a loss on  extinguishment  of debt  of  $33,692,000,  representing
    approximately  (i) $23,554,000 of cash payments for premium and consent fees
    relating to the early  extinguishment  of $214,868,000  aggregate  principal
    amount of IHS' senior  subordinated  notes and (ii)  $10,138,000 of deferred
    financing costs written off in connection with the early  extinguishment  of
    such debt and the Company's revolving credit facility. Such loss, reduced by
    the related income tax effect of $13,140,000,  is presented in the statement
    of operations for the year ended December 31, 1997 as an extraordinary  loss
    of $20,552,000.

(5) Represents  the  write-off,  net of income tax benefit,  of the  unamortized
    balance  of  costs  of  business  process   reengineering   and  information
    technology projects.

(6) The share and per share  information  for the years ended December 31, 1993,
    1994,  1995 and 1996 and the three  months  ended  March 31,  1997 have been
    restated  to reflect  share and per share  information  in  accordance  with
    Statement of Financial  Accounting  Standards No. 128, "Earnings per Share,"
    which was required to be adopted by the Company effective with its financial
    statements  for the year ended  December  31,  1997.  The  diluted  weighted
    average number of common shares outstanding for the years ended December 31,
    1993,  1994 and 1996 and the three  months  ended  March  31,  1997 and 1998
    includes  the  assumed  conversion  of the  Debentures  into  Common  Stock.
    Additionally,  interest  expense  and  amortization  of  underwriting  costs
    related to such Debentures are added,  net of tax, to income for the purpose
    of  calculating   diluted  earnings  per  share.  Such  amounts   aggregated
    $4,516,000, $10,048,000, $9,888,000, $2,452,000 and $2,388,000 for the years
    ended December 31, 1993,  1994 and 1996 and the three months ended March 31,
    1997 and 1998,  respectively.  The diluted weighted average number of common
    shares  outstanding  for the years ended December 31, 1995 and 1997 does not
    include the assumed  conversion of the  Debentures  or the related  interest
    expense and underwriting costs, as such conversion would be anti-dilutive.

                                       20

                         REDEMPTION OF THE DEBENTURES
                        AND ALTERNATIVES TO REDEMPTION

     The Company has called for  redemption,  on the  Redemption  Date (June 29,
1998),  unless  previously  converted into Common Stock,  all of the outstanding
Debentures.  As of May 28,  1998,  $115,000,000  aggregate  principal  amount of
Debentures was outstanding.

     The following alternatives are available to holders of Debentures:

     1.  Conversion  into Common Stock.  Holders may convert  Debentures (or any
portion thereof which is $1,000 or an integral multiple thereof) into the Common
Stock of the Company at a conversion  price of $32.125 per share of Common Stock
(equivalent to 31.13 shares of Common Stock for each $1,000  principal amount of
Debentures). No fractional shares of Common Stock will be issued upon conversion
of  Debentures.  Instead,  the Company will pay a cash  adjustment in respect of
such  fraction in an amount equal to the same  fraction of the Closing Price (as
defined  below) at the Close of Business on the day of  conversion  (or, if such
day is not a Trading Day (as  defined  below),  on the  Trading Day  immediately
preceding such day). Debentures  surrendered for conversion will not be entitled
to interest  accrued to the date of conversion.  "Closing  Price" means the last
reported  sales price  regular way or, in case no such reported sale takes place
on such day,  the average of the reported  closing bid and asked prices  regular
way,  in either  case on the NYSE.  "Trading  Day" means each  Monday,  Tuesday,
Wednesday,  Thursday  and  Friday,  other than any day on which  securities  are
generally not traded on the NYSE. The Debentures  will not be convertible  after
5:00 P.M., New York City time, on the Redemption Date.

     To convert  Debentures into Common Stock, the holder thereof must surrender
such Debentures prior to 5:00 P.M. New York City time, on the Redemption Date to
The Bank of New York, as paying and conversion agent (the "Paying and Conversion
Agent").  Such surrender of any Debenture must be accompanied by a duly executed
notice of the holder's  election to convert in the form  provided on the reverse
side of such Debenture (the  "Conversion  Notice").  The Conversion  Notice must
also state the name or names,  together with the address or addresses,  in which
the Common Stock shall be issuable  upon the  conversion  if different  from the
registered holder of the Debentures surrendered.  Each Debenture surrendered for
conversion must be accompanied by proper  assignments  thereof to the Company or
in blank for transfer and any  requisite  federal or state  transfer tax stamps.
The Conversion  Notice that must be given to the Paying and Conversion Agent may
be provided  by  surrendering  Debentures  accompanied  by a properly  completed
Letter  of  Transmittal  in the  form  provided  to all  registered  holders  of
Debentures  (each,  a "Letter of  Transmittal").  Each  holder's  signature in a
Letter of  Transmittal  or any other  Conversion  Notice must be guaranteed by a
commercial bank or trust company having an office or correspondent in the United
States,  a  member  firm  of a  national  securities  exchange  or the  National
Association of Securities Dealers,  Inc. or an "eligible guarantor  institution"
within the meaning of Rule 17Ad-15  under the  Exchange Act (each,  an "Eligible
Institution") if shares of Common Stock are to be delivered other than to and in
the name of the registered  holder of the Debentures  converted.  Holders should
inquire of such Eligible Institutions  sufficiently in advance of the Redemption
Date  whether  there  are any  dollar  limitations  on the  principal  amount of
Debentures  with respect to which  signatures may be guaranteed by such Eligible
Institutions.  A Letter of Transmittal  and any other  Conversion  Notice,  once
given to the Paying and  Conversion  Agent,  is not  revocable.  As  promptly as
practicable  after the surrender of a Debenture as aforesaid,  the Company shall
deliver  to the  holder  at the  office of the  Paying  and  Conversion  Agent a
certificate  or  certificates  for the  number of full  shares  of Common  Stock
issuable upon the conversion of such Debenture or portion thereof and a check in
an amount  equivalent to the value of any fractional  shares otherwise  issuable
upon such conversion. Debentures surrendered for conversion will not be entitled
to  interest  accrued to the date of  conversion.  See  "Paying  and  Conversion
Agent."

     Debenture  holders wishing to convert their Debentures whose Debentures are
not immediately  available or who cannot deliver their  Debentures and all other
documents  required by the Letter of  Transmittal  to the Paying and  Conversion
Agent on or prior to 5:00 p.m., New York City time, on the  Redemption  Date may
elect to convert their Debentures pursuant to the following procedures: (a) such
election to convert  must be made by or through an Eligible  Institution,  (b) a
properly completed and

                                       21

duly executed Notice of Guaranteed  Delivery in the form provided by the Company
to  all  registered  holders  of  Debentures  (each,  a  "Notice  of  Guaranteed
Delivery")  must be received by the Paying and  Conversion  Agent on or prior to
5:00 p.m., New York City time, on the Redemption Date, and (c) the Debentures in
proper form for transfer,  together with a properly  completed and duly executed
Letter of Transmittal and all other documents required thereby, must be received
by the Paying and  Conversion  Agent within three  business  days after the date
such Notice of  Guaranteed  Delivery  is  received by the Paying and  Conversion
Agent.  Notwithstanding the foregoing,  shares of Common Stock will be issued in
respect of Debentures  surrendered  for conversion  only after timely receipt by
the  Paying  and  Conversion  Agent of the  surrendered  Debentures,  a properly
completed  and duly  executed  Letter of  Transmittal  and any  other  documents
required by the Letter of Transmittal.

     Each holder of Debentures that does not directly hold  certificates for its
Debentures,  but instead maintains its holdings  indirectly in an account with a
broker or other intermediary (each, a "Beneficial  Holder") must comply with the
procedures of such intermediary to convert such Beneficial Holder's  Debentures.
Such an intermediary may maintain its holdings with The Depository Trust Company
("DTC").  In those instances,  the procedures of DTC must also be followed for a
Beneficial Holder to convert its Debentures.

     IT IS THE  RESPONSIBILITY OF EACH BENEFICIAL HOLDER TO GIVE INSTRUCTIONS TO
ITS  INTERMEDIARY  IN  SUFFICIENT  TIME  FOR  THAT   INTERMEDIARY,   ANY  HIGHER
INTERMEDIARIES  AND THE RECORD  HOLDER OF SUCH  BENEFICIAL  HOLDER'S  DEBENTURES
(WHICH MAY BE DTC) TO TAKE THE ACTIONS WHICH ARE NECESSARY TO EFFECT  CONVERSION
OF SUCH BENEFICIAL  HOLDER'S  DEBENTURES PRIOR TO 5:00 P.M., NEW YORK CITY TIME,
ON THE REDEMPTION DATE.

     The Company will decide,  in its sole  discretion,  all questions as to the
form of documents and the validity,  eligibility (including time of receipt) and
acceptance  for  conversion  by the  Company  of any  Debentures.  Any defect or
irregularity in the surrender or delivery of any document in connection with the
conversion of Debentures may result in such  Debentures not being converted into
Common Stock and, therefore, being redeemed on the Redemption Date.

     THE RIGHT TO CONVERT  DEBENTURES  INTO COMMON STOCK EXPIRES AT THE CLOSE OF
BUSINESS ON THE REDEMPTION DATE, TIME BEING OF THE ESSENCE.  FROM AND AFTER THAT
DATE AND TIME,  HOLDERS OF DEBENTURES  WILL BE ENTITLED  ONLY TO THE  REDEMPTION
PRICE, WITHOUT INTEREST.

     The Common  Stock is traded on the NYSE under the symbol  "IHS." On May 28,
1998, the reported  closing price of the Common Stock on the NYSE Composite Tape
was $38.1875 per share. A holder of Debentures who converted such  Debentures on
that date would have  received  Common  Stock (and cash in lieu of a  fractional
share) having a market value, based on such price on that date, of approximately
$1,188.78  for each $1,000  principal  amount of Debentures  converted.  If such
Debentures were  surrendered for redemption on the Redemption  Date, such holder
would receive $1,059.83 in cash for each $1,000 principal amount.

     AS LONG AS THE MARKET PRICE OF THE COMMON STOCK  REMAINS AT OR ABOVE $34.05
PER SHARE,  THE HOLDERS OF DEBENTURES  WHO ELECT TO CONVERT WILL  RECEIVE,  UPON
CONVERSION, COMMON STOCK (INCLUDING CASH, IF ANY, RECEIVED IN LIEU OF FRACTIONAL
SHARES)  HAVING A GREATER MARKET VALUE THAN THE AMOUNT OF CASH  RECEIVABLE  UPON
REDEMPTION OF SUCH DEBENTURES (BEFORE DEDUCTING ANY TAXES, COMMISSIONS AND OTHER
COSTS WHICH WOULD LIKELY BE INCURRED ON SALE OF THE COMMON STOCK  RECEIVED  UPON
CONVERSION OF THE DEBENTURES).  IT SHOULD BE NOTED,  HOWEVER,  THAT THE PRICE OF
THE COMMON STOCK  RECEIVED  UPON  CONVERSION  WILL  FLUCTUATE IN THE MARKET.  NO
ASSURANCE  CAN BE GIVEN AS TO THE PRICE OF THE COMMON  STOCK AT ANY FUTURE TIME,
AND THE HOLDERS  SHOULD EXPECT TO INCUR VARIOUS  EXPENSES OF SALE IF SUCH COMMON
STOCK IS SOLD.


                                       22

     2. Sale in Open Market. Holders may sell the Debentures in the open market.
Holders of  Debentures  who wish to sell  their  Debentures  in the open  market
should  consult with their own  advisors  regarding if and when they should sell
their  Debentures and the tax  consequences  thereof.  Holders may incur various
fees and expenses in connection with any such sale.

     3. Redemption.  Holders may allow the Debentures to be redeemed on June 29,
1998. Pursuant to the terms of the Indenture between the Company and The Bank of
New York, as Trustee,  dated as of December 1, 1992,  holders of the  Debentures
will be entitled  to receive  upon  redemption  103.0% of the  principal  amount
thereof, plus interest accruing from January 1, 1998 to the Redemption Date (the
"Redemption  Price"). A holder of $1,000 principal amount of Debentures redeemed
at the  Redemption  Price  would  receive  $1,059.83  in  cash.  Payment  of the
Redemption  Price will be made by the Paying and Conversion Agent upon surrender
of  Debentures  to the Paying  and  Conversion  Agent by  holders of  Debentures
accompanied  by a  properly  completed  Letter  of  Transmittal.  Each  holder's
signature  in a  Letter  of  Transmittal  must  be  guaranteed  by  an  Eligible
Institution  if the Redemption  Price for Debentures  surrendered by such holder
for  redemption  is to be paid  other  than  to the  registered  holder  of such
Debentures. Holders should inquire of such Eligible Institutions sufficiently in
advance of the Redemption  Date whether there are any dollar  limitations on the
principal  amount  of  Debentures  with  respect  to  which  signatures  may  be
guaranteed  by such Eligible  Institutions.  On and after the  Redemption  Date,
interest will cease to accrue and holders of Debentures will not have any rights
as such  holders  other  than the right to receive  the  Redemption  Price.  See
"Paying and Conversion Agent."

     The alternatives available to the holders of Debentures are illustrated,
in tabular form, below, based upon the Redemption Price of $1,059.83. Reference
is made to "Certain Federal Income Tax Considerations."

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

     The following is a general  summary of certain United States federal income
tax considerations relevant to the conversion,  redemption or sale of Debentures
by a  beneficial  owner of  Debentures.  This  summary is based on the  Internal
Revenue Code of 1986, as amended (the "Code"),  Treasury Regulations  (including
proposed regulations and temporary regulations) promulgated thereunder, Internal
Revenue Service ("IRS") rulings, official pronouncements and judicial decisions,
all as in effect on the date  hereof  and all of which are  subject  to  change,
possibly with retroactive effect, or different interpretations.  This summary is
applicable  only to holders who are "United  States  persons" for federal income
tax purposes  and who hold  Debentures  as capital  assets and who will hold any
Common  Stock   received  on  conversion   of  Debentures  as  capital   assets.
Additionally,  this summary is not  applicable to non-United  States persons who
have an indirect  interest in Debentures or Common Stock through a United States
partnership, trust or estate, or other flow-through entity.

     This summary does not discuss all the tax consequences that may be relevant
to a particular holder in light of the holder's particular  circumstances and it
is not intended to be applicable in all respects to all categories of investors,
some  of whom -- such as  insurance  companies,  tax-exempt  persons,  financial
institutions,   regulated  investment   companies,   dealers  in  securities  or
currencies,  persons that hold the  Debentures as a position in a "straddle," as
part of a  "synthetic  security,"  "hedge,"  "conversion  transaction"  or other
integrated investment,  persons that enter into "short sales against the box" or
certain other  "constructive  sales"  involving the Debentures or  substantially
identical  property,  or persons whose functional  currency is other than United
States  dollars -- may be subject to different  rules not  discussed  below.  In
addition,  this  summary  does not  address  any  state,  local or  foreign  tax
considerations that may be relevant to a particular holder.

     HOLDERS  OF  DEBENTURES  ARE  ADVISED  TO  CONSULT  THEIR OWN TAX  ADVISORS
REGARDING  THE  FEDERAL,  STATE,  LOCAL  AND  FOREIGN  TAX  CONSEQUENCES  OF THE
CONVERSION,  SALE  OR  REDEMPTION  OF THE  DEBENTURES  IN  LIGHT  OF  THEIR  OWN
PARTICULAR CIRCUMSTANCES.

CONVERSION OF DEBENTURES

     In general,  no gain or loss will be recognized on conversion of Debentures
solely into Common Stock.  The tax basis for the Common Stock received upon such
conversion will be equal to the tax basis of the Debentures  converted  (reduced
by the portion of such basis  allocable to any fractional  share of Common Stock
paid in cash).  The holding  period for the Common Stock  generally will include
the holding period of the Debentures converted.  Except as discussed below under
"Market  Discount,"  a holder  generally  will  recognize  gain (or loss) upon a
conversion  to the extent  that any cash paid in lieu of a  fractional  share of
Common Stock exceeds (or is less than) its tax basis in such fractional share.

SALE OR REDEMPTION OF DEBENTURES

     Generally, the sale or redemption of Debentures will result in taxable gain
or loss equal to the difference  between (i) the amount realized  (except to the
extent such amount is attributable to accrued  interest not previously  included
in income,  which amount  generally will be taxable as ordinary income) and (ii)
the holder's  adjusted tax basis in the  Debentures.  Except as discussed  below
under "Market  Discount,"  such gain or loss will be capital gain or loss.  Such
gain or loss will be long-term  capital  gain or loss if the holding  period for
the  Debentures  exceeds  one  year.  In the case of a  non-corporate  holder of
Debentures,  any such capital  gain will be subject to tax at a maximum  federal
income tax rate of 28% if the holder's  holding period in the Debentures is more
than one year but not more than 18 months  and at a maximum  federal  income tax
rate of 20% if the holder's  holding  period in the  Debentures  is more than 18
months.

MARKET DISCOUNT

     Special rules will apply to Debentures  acquired  with market  discount.  A
market discount note is, generally, a note the principal amount of which exceeds
the holder's  basis in the note  immediately  after  acquisition  by more than a
specified de minimis amount. Generally, any gain recognized on the sale or

                                       25


redemption of a market  discount note will be treated as ordinary  income to the
extent of the accrued market  discount on such note not  previously  included in
income. In general,  market discount accrues on a straight line basis or, at the
option of the holder, at a constant yield to maturity basis.

     Although  the matter is not free from doubt,  a holder of a Debenture  with
market  discount  should not have to recognize  income on the  conversion of the
Debenture,  even with  respect to market  discount  that has accrued but has not
been taken into account. Market discount not recognized on conversion will carry
over to the Common Stock acquired upon conversion thereof and will be recognized
as ordinary income to the extent of gain recognized upon the disposition of such
Common Stock,  including any deemed  disposition of fractional  shares of Common
Stock for cash at the time of conversion.

SALE OR DISPOSITION OF COMMON STOCK

     Subject to the  discussion  under "Market  Discount"  above,  a holder will
recognize  gain or loss on the sale or exchange of Common  Stock  received  upon
conversion of a Debenture equal to the difference between the amount realized on
such sale or exchange  and the  holder's  adjusted tax basis in the Common Stock
sold or exchanged.

BACKUP WITHHOLDING

     A holder of a  Debenture  or  Common  Stock  issued  upon  conversion  of a
Debenture may be subject to backup  withholding at a rate of 31% with respect to
the proceeds of a sale or redemption of such  Debenture or Common Stock,  as the
case may be,  unless (i) such holder is a  corporation  or comes within  certain
other exempt  categories  and,  when  required,  demonstrates  this fact or (ii)
provides a taxpayer identification number,  certifies as to no loss of exemption
from  backup   withholding,   and  otherwise  complies  with  applicable  backup
withholding  rules. The amount of backup  withholding from a payment to a holder
will be allowed as a credit against the holder's federal income tax liability.

                         DESCRIPTION OF CAPITAL STOCK

     The following summary does not purport to be complete and is subject in all
respects  to  the  applicable  provisions  of  the  DGCL,  IHS'  Third  Restated
Certificate of Incorporation, as amended (the "IHS Certificate"),  and the terms
of  IHS'  Stockholders'  Rights  Plan,  each  of  which  is an  exhibit  to  the
Registration Statement of which this Prospectus is a part.

AUTHORIZED CAPITAL STOCK

     IHS is authorized to issue up to  150,000,000  shares of Common Stock,  par
value $.001 per share, 46,425,880 shares of which were issued and outstanding at
May 27,  1998,  and  15,000,000  shares  of  Preferred  Stock,  none of which is
outstanding  as of the date  hereof.  Each  outstanding  share of  Common  Stock
currently has attached to it one preferred  share purchase  right,  as described
under "-- Stockholders' Rights Plan." 

COMMON STOCK

     Holders  of Common  Stock are  entitled  to one vote for each share held of
record on all matters to be submitted to a vote of the  stockholders  and do not
have  preemptive  rights.  Subject to preferences  that may be applicable to any
outstanding  shares of Preferred Stock,  holders of Common Stock are entitled to
receive ratably such dividends,  if any, as may be declared from time to time by
the IHS Board of  Directors  (the "IHS  Board") out of funds  legally  available
therefor.   All   outstanding   shares  of  Common  Stock  are  fully  paid  and
nonassessable. In the event of any liquidation, dissolution or winding-up of the
affairs of IHS, holders of Common Stock will be entitled to share ratably in the
assets of IHS  remaining  after  payment or provision for payment of all of IHS'
debts and  obligations  and  liquidation  payments to holders of any outstanding
shares of Preferred Stock.

PREFERRED STOCK

     The IHS Board, without further stockholder authorization,  is authorized to
issue shares of Preferred  Stock in one or more series and to determine  and fix
the rights, preferences and privileges of each series, including dividend rights
and preferences  over dividends on the Common Stock and one or more other series
of  Preferred  Stock,  conversion  rights,  voting  rights (in addition to those
provided by law),  redemption rights and the terms of any sinking fund therefor,
and rights upon  liquidation,  dissolution or winding up, including  preferences
over the Common  Stock and one or more series of Preferred  Stock.  Although IHS
has no present  plans to issue any shares of  Preferred  Stock,  the issuance of
shares of Preferred  Stock,  or the issuance of rights to purchase  such shares,
may have the effect of delaying,  deferring or preventing a change in control of
IHS or an unsolicited acquisition proposal.

     IHS has  designated  750,000  shares of Preferred  Stock as Series A Junior
Participating  Cumulative Preferred Stock, $.01 par value per share (the "Series
A Preferred  Stock").  The rights,  preferences  and  privileges of the Series A
Preferred Stock are set forth under "-- Stockholders' Rights Plan."

STOCKHOLDERS' RIGHTS PLAN

     The  following  is a  description  of IHS'  Stockholders'  Rights Plan (the
"Rights  Plan").  The  description  thereof set forth below is  qualified in its
entirety by  reference  to the Rights  Plan, a copy of which has been filed with
the  Commission.  See  "Available  Information"  and  "Incorporation  of Certain
Documents by Reference."

     The  Rights  Plan  provides  that one  preferred  stock  purchase  right (a
"Right")  will be issued  with each share of Common  Stock  (whether  originally
issued or from IHS' treasury) prior to the Rights  Distribution Date (as defined
herein). When exercisable, each Right entitles the registered holder to purchase
from IHS one  one-hundredth of a share of Series A Preferred Stock at a price of
$135.00  per one  one-hundredth  of a share of  Series A  Preferred  Stock  (the
"Purchase Price"), subject to adjustment.

     Until the earlier to occur of (i) 10 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
Common Stock or (ii) 10 business days (or such later date as may be deter-

                                       27

mined by action of the IHS  Board  prior to such time as any  person or group of
affiliated  persons becomes an Acquiring  Person) following the commencement of,
or  announcement  of an intention to make, 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 the outstanding  Common Stock (the earlier of such dates
being called the "Distribution  Date"),  the Rights will be evidenced by all the
Common Stock share  certificates  and will be transferred  with the Common Stock
certificates,  and no separate Rights certificates will be distributed.  As soon
as practicable following the Distribution Date, separate certificates evidencing
the  Rights  ("Right  Certificates")  will be mailed to holders of record of the
Common  Stock as of the  close of  business  on the  Distribution  Date and such
separate Right Certificates alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on September  26, 2005 (the "Final  Expiration  Date"),  unless the Final
Expiration  Date is  extended  or unless  the  Rights are  earlier  redeemed  or
exchanged by IHS, in each case, as described below.

     The Purchase Price payable,  and the number of shares of Series A Preferred
Stock or other securities or property  issuable,  upon exercise of the Right are
subject to adjustment from time to time to prevent  dilution (i) in the event of
a stock dividend on, or a subdivision,  combination or reclassification  of, the
Series A  Preferred  Stock,  (ii)  upon the  grant to  holders  of the  Series A
Preferred  Stock of certain  rights or  warrants  to  subscribe  for or purchase
shares  of  Series A  Preferred  Stock  with a  conversion  price  less than the
then-current  market  price of the  Series A  Preferred  Stock or (iii) upon the
distribution  to  holders  of the  Series  A  Preferred  Stock of  evidences  of
indebtedness or assets  (excluding  regular  periodic cash dividends paid out of
earnings or retained  earnings or dividends payable in Series A Preferred Stock)
or of subscription rights or warrants (other than those referred to above).

     The number of outstanding  Rights and the number of one one-hundredths of a
share of Series A Preferred  Stock issuable upon exercise of each Right are also
subject to  adjustment  in the event of a stock  split of the Common  Stock or a
stock  dividend on the Common  Stock  payable in Common  Stock or  subdivisions,
consolidations or combinations of the Common Stock occurring,  in any such case,
prior to the Distribution Date.

     Series A Preferred Stock  purchasable  upon exercise of the Rights will not
be  redeemable.  Each share of Series A  Preferred  Stock will be  entitled to a
minimum  preferential  quarterly  dividend  payment  of $1 per share but will be
entitled to an aggregate  dividend of 100 times the dividend  declared per share
of Common  Stock.  In the event of  liquidation,  the  holders  of the  Series A
Preferred Stock will be entitled to a minimum  preferential  liquidation payment
of $100 per share but will be entitled to an aggregate  payment of 100 times the
payment made per share of Common Stock.  Each share of Series A Preferred  Stock
will have 100 votes,  voting together with the shares of Common Stock.  Finally,
in the event of any merger,  consolidation or other  transaction in which Common
Stock is exchanged,  each share of Series A Preferred  Stock will be entitled to
receive 100 times the amount  received per share of Common  Stock.  These rights
are protected by customary antidilution provisions. The Series A Preferred Stock
will, if issued,  be junior to any other series of Preferred  Stock which may be
authorized and issued by IHS,  unless the terms of any such other series provide
otherwise.  Once the  shares of Series A  Preferred  Stock are  issued,  the IHS
Certificate  may not be  amended in a manner  which  would  materially  alter or
change the powers, preferences or special rights of the Series A Preferred Stock
so as to affect them adversely  without the  affirmative  vote of the holders of
two-thirds or more of the outstanding shares of Series A Preferred Stock, voting
separately as a class.

     Because  of  the  nature  of  the  Series  A  Preferred  Stock's  dividend,
liquidation and voting rights, the value of the one one-hundredth  interest in a
share of Series A Preferred Stock purchasable upon exercise of each Right should
approximate the value of one share of Common Stock.

     In the event that IHS is acquired in a merger or other business combination
transaction or 50% or more of its consolidated  assets or earning power are sold
after a person or group has become an Acquiring Person, 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 exercise price of the Right,  that
number of shares of common stock of the  acquiring  company which at the time of
such transaction will have a

                                       28

market value of two times the exercise price of the Right. In the event that any
person or group of affiliated or associated persons becomes an Acquiring Person,
proper provision shall be made so that each holder of a Right, other than Rights
beneficially owned by the Acquiring Person (which will thereafter be void), will
thereafter  have  the  right  to  receive  upon  exercise  such  number  of  one
one-hundredths  of a share of Series A Preferred Stock as shall equal the result
obtained by (x) multiplying the then current Purchase Price by the number of one
one-hundredths  of a share of Series A Preferred Stock for which a Right is then
exercisable  and dividing  that product by (y) 50% of the then current per share
market price of the Common Stock.

     At any time after any person or group becomes an Acquiring Person and prior
to the  acquisition  by such  person or group of 50% or more of the  outstanding
Common Stock,  the IHS Board may exchange the Rights (other than Rights owned by
such  person or group  which will have become  void),  in whole or in part,  for
consideration  consisting  of  one-half  the  securities  of IHS  that  would be
issuable at such time upon exercise of one Right.

     With  certain  exceptions,  no  adjustment  in the  Purchase  Price will be
required until  cumulative  adjustments  require an adjustment of at least 1% in
such Purchase  Price.  No fractional  shares of Series A Preferred Stock will be
issued (other than fractions which are integral  multiples of one  one-hundredth
of a share of Series A Preferred  Stock,  which may, at the  election of IHS, be
evidenced by depositary  receipts)  and in lieu  thereof,  an adjustment in cash
will be made based on the market  price of the Series A  Preferred  Stock on the
last trading day prior to the date of exercise.

     At any time prior to the tenth day following the acquisition by a person or
group of affiliated or associated persons of beneficial ownership of 20% or more
of the outstanding  Common Stock,  the IHS Board may redeem the Rights in whole,
but not in  part,  at a price  of  $.01  per  Right  (the  "Redemption  Price");
provided,  however,  that,  for the  120-day  period  after any date of a change
(resulting from a proxy or consent  solicitation) in a majority of the IHS Board
in office at the  commencement  of such  solicitation,  the  Rights  may only be
redeemed  if (A) there are  directors  then in office  who were in office at the
commencement of such solicitation and (B) the IHS Board, with the concurrence of
a majority of such directors then in office, determines that such redemption is,
in  their  judgment,  in the best  interests  of IHS and its  stockholders.  The
redemption  of the Rights may be made  effective at such time on such basis with
such  conditions  as  the  IHS  Board  in its  sole  discretion  may  establish.
Immediately upon any 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.

     The terms of the Rights may be amended by the IHS Board without the consent
of the holders of the Rights,  except that from and after a Distribution Date no
such amendment may adversely affect the interests of the holders of the Rights.

     Until a Right is  exercised,  the  holder  thereof,  as such,  will have no
rights as a stockholder of IHS, including, without limitation, the right to vote
or to receive dividends.

     The Rights  have  certain  anti-takeover  effects.  The  Rights  will cause
substantial  dilution to a person or group that  attempts to acquire IHS without
conditioning  the offer on the Rights being redeemed or a substantial  number of
Rights  being  acquired.  The effect of the Rights may be to inhibit a change in
control of IHS  (including  through a third party  tender offer at a price which
reflects a premium to the then prevailing  trading price) that may be beneficial
to IHS  stockholders.  See "Risk  Factors  -- Effect  of  Certain  Anti-Takeover
Provisions."

LIMITATIONS ON LIABILITY OF OFFICERS AND DIRECTORS

     IHS'  Certificate  contains a provision  eliminating  or limiting  director
liability to IHS and its  stockholders for monetary damages arising from acts or
omissions in the  director's  capacity as a director.  The  provision  does not,
however,  eliminate  or limit the  personal  liability of a director (i) for any
breach of such director's duty of loyalty to IHS or its  stockholders,  (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing  violation  of law,  (iii)  under  the DGCL for  unlawful  dividends  or
unlawful stock purchases or redemptions,  or (iv) for any transaction from which
the director derived an improper personal benefit. This provision offers persons
who serve on the IHS Board

                                       29


protection  against awards of monetary damages  resulting from breaches of their
duty of care (except as indicated  above).  As a result of this  provision,  the
ability of IHS or a  stockholder  thereof to  successfully  prosecute  an action
against a director  for a breach of his duty of care is  limited.  However,  the
provision  does not affect the  availability  of equitable  remedies  such as an
injunction or rescission based upon a director's breach of his duty of care. The
Commission  has taken the  position  that the  provision  will have no effect on
claims arising under the federal securities laws.

     In addition,  the IHS Certificate and the IHS By-laws provide for mandatory
indemnification rights, subject to limited exceptions, to any director, officer,
employee  or  agent  of IHS  who,  by  reason  of the  fact  that he or she is a
director,  officer,  employee or agent of IHS, is involved in a legal proceeding
of any nature. Such  indemnification  rights include  reimbursement for expenses
incurred by such director,  officer,  employee, or agent in advance of the final
disposition of such proceeding in accordance  with the applicable  provisions of
the DGCL. In addition, IHS has entered into indemnification  agreements with its
officers and directors. 

TRANSFER AGENT AND REGISTRAR

     The Transfer  Agent and  Registrar  for the Common Stock is American  Stock
Transfer & Trust Company, New York, New York.

                                       30

                              STANDBY ARRANGEMENTS

     Under the terms and  subject to the  conditions  in the  Standby  Agreement
dated  May 29,  1998  between  the  Company  and  the  Purchaser  (the  "Standby
Agreement"),  the  Purchaser  has agreed to purchase  from the  Company,  at the
Company's  option,  for  settlement  on July 2, 1998,  such  number of shares of
Common Stock as would have been issuable upon  conversion of any Debentures that
were not  surrendered  for conversion by the Close of Business on the Redemption
Date for a purchase price per share equal to $34.05. 

     On or  prior to the  Redemption  Date,  the  Purchaser  may  also  purchase
Debentures in the open market or otherwise.  The Purchaser has agreed to convert
into Common Stock all  Debentures  owned by it. Such Common Stock may be used by
the Purchaser to cover any short position in the Common Stock established by the
Purchaser.

     The Company has been advised by the Purchaser that it proposes to offer for
resale to the public at prices set from time to time by the Purchaser any shares
of Common Stock  purchased from the Company or acquired upon  conversion and not
used to cover any short  position.  The  Purchaser  may also make  sales of such
shares to certain securities dealers at prices that may reflect concessions from
the prices at which such shares are then being offered to the public. The amount
of such concessions will be determined from time to time by the Purchaser.

     Pursuant to the terms of the Standby  Agreement and in consideration of its
obligations  thereunder,  the Company has agreed to pay the Purchaser the sum of
(1)  $1,828,213 and (2) an additional  $1.36 per share for Purchased  Securities
(as defined below) and Compensible Conversion Securities (as defined below), but
the fee specified in clause (2) will be payable only if the Purchased Securities
and Compensible  Conversion Securities exceed, in the aggregate,  178,988 shares
of Common Stock and then only with respect to that number of shares of Purchased
Securities and Compensible  Conversion  Securities that in the aggregate exceeds
178,988 shares. Additionally, the Purchaser has agreed to pay to the Company 50%
of the excess,  if any, of (a) the aggregate  proceeds received by the Purchaser
from  the  sale  by the  Purchaser  of  Purchased  Securities  (net  of  selling
concessions and other  reasonable  expenses of sale and any transfer taxes) over
(b) an amount equal to the aggregate number of Purchased  Securities  multiplied
by the average price paid by the Purchaser for such shares. For purposes hereof,
the term  "Purchased  Securities"  means shares of Common Stock purchased by the
Purchaser  pursuant  to  the  Standby  Agreement,  and  "Compensible  Conversion
Securities"  means  shares  of  Common  Stock  acquired  by the  Purchaser  upon
conversion of  Debentures,  or that the Purchaser  obtained the right to acquire
upon  conversion of  Debentures,  on a date when the last reported sale price of
the Common Stock on the NYSE was less than or equal to $34.05. 

     The  Company  has  agreed  to  indemnify  the  Purchaser   against  certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments the Purchaser may be required to make in respect thereof.

     The  Company  and  its  executive   officers  have  agreed,   with  certain
exceptions,  from the date of the Standby  Agreement through the Redemption Date
(and the Company and its  executive  officers have agreed that, if the Purchaser
purchases or  receives,  in the  aggregate,  more than  450,000  shares,  for an
additional  period  of 90 days  after the  Redemption  Date)  without  the prior
written  consent of the  Purchaser,  not to offer,  sell or contract to sell, or
otherwise  dispose of (or enter into any  transaction  which is designed  to, or
might  reasonably be expected to, result in the  disposition  (whether by actual
disposition  or  effective  economic  disposition  due  to  cash  settlement  or
otherwise)  by the  Company or such  individuals),  directly or  indirectly,  or
announce the  offering  of, any other  shares of Common Stock or any  securities
convertible into, or exchangeable for, shares of Common Stock.

     The  Purchaser has performed  investment  banking  services for the Company
from  time to time in the  ordinary  course  of its  business  for  which it has
received  customary  compensation,  including acting as the financial advisor to
the  Company  in  connection  with  the  Company's   acquisition  of  the  Coram
Lithotripsy Division and as lead manager in connection with private offerings of
the  Company's  9 1/2%  Senior  Subordinated  Notes due 2007 in May 1997 and the
Company's 9 1/4%  Senior  Subordinated  Notes due 2008 in  September  1997.  The
Purchaser may assist the Company in providing  information  regarding conversion
of Debentures but will not receive any  compensation by the Company for any such
assistance.

                                       31

     In connection  with the sale of Common Stock to the  Purchaser  pursuant to
the Standby Agreement,  the Purchaser may purchase Debentures,  which may result
in the  maintenance of the price of the Common Stock at a level above that which
might  otherwise  prevail in the open market or may otherwise  affect the market
price of the Common Stock. Such purchases are not required,  and, if undertaken,
may be discontinued at any time.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Under the DGCL, a corporation may include  provisions in its certificate of
incorporation that will relieve its directors of monetary liability for breaches
of their fiduciary duty to the corporation,  except under certain circumstances,
including a breach of the director's  duty of loyalty,  acts or omissions of the
director not in good faith or which involve intentional  misconduct or a knowing
violation  of law,  the  approval  of an  improper  payment of a dividend  or an
improper  purchase by the corporation of stock or any transaction from which the
director  derived an improper  personal  benefit.  The Company's  Third Restated
Certificate of Incorporation,  as amended, provides that the Company's directors
are not liable to the  Company or its  stockholders  for  monetary  damages  for
breach of their fiduciary duty, subject to the described exceptions specified by
the DGCL.

     Section 145 of the DGCL grants to the Company the power to  indemnify  each
officer and director of the Company against liabilities and expenses incurred by
reason of the fact that he is or was an officer or director of the Company if he
acted in good  faith  and in a manner  he  reasonably  believed  to be in or not
opposed to the best  interests of the Company and,  with respect to any criminal
action or  proceeding,  had no  reasonable  cause to  believe  his  conduct  was
unlawful. The Company's Third Restated Certificate of Incorporation, as amended,
and  By-laws,  as  amended,  provide  for  indemnification  of each  officer and
director  of the  Company  to the  fullest  extent  permitted  by the  DGCL.  In
addition,  IHS has entered into  indemnity  agreements  with its  directors  and
executive  officers,  a form of  which  is  included  as  Exhibit  10.72 to IHS'
Registration  Statement on Form S-1,  No.  33-39339,  effective  March 31, 1992.
Section  145 of the DGCL also  empowers  the Company to  purchase  and  maintain
insurance  on behalf of any person who is or was an officer or  director  of the
Company  against  liability  asserted  against  or  incurred  by him in any such
capacity,  whether or not the  Company  would have the power to  indemnify  such
officer or director  against such liability under the provisions of Section 145.
The Company has  purchased and  maintains a directors'  and officers'  liability
policy for such purposes.

     Under  Section  8 of the  Standby  Purchase  Agreement,  the  Purchaser  is
obligated  under certain  circumstances,  to indemnify  officers,  directors and
controlling  persons  of the  Company  against  certain  liabilities,  including
liabilities  under the Securities Act of 1933.  Reference is made to the form of
Standby Purchase Agreement filed as Exhibit 1 hereto.

ITEM 17. UNDERTAKINGS.

     (a) The undersigned registrant hereby undertakes:

       (1) To file, during any period in which offers or sales are being made, a
   post-effective amendment to this registration statement:

          (i) To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

          (ii) To reflect in the  prospectus  any facts or events  arising after
       the  effective  date of the  registration  statement  (or the most recent
       post-effective   amendment   thereof)  which,   individually  or  in  the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement;

          (iii) To include any material  information with respect to the plan of
       distribution not previously  disclosed in the  registration  statement or
       any material change to such information in the registration statement;

     Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
the information  required to be included in a post-effective  amendment by those
paragraphs is contained in periodic reports filed by the registrant  pursuant to
Section  13 or Section  15(d) of the  Securities  Exchange  Act of 1934 that are
incorporated by reference in the registration statement.

       (2)  That,  for the  purpose  of  determining  any  liability  under  the
   Securities Act of 1933, each such post-effective amendment shall be deemed to
   be a new registration  statement  relating to the securities offered therein,
   and the  offering of such  securities  at that time shall be deemed to be the
   initial bona fide offering thereof.

       (3) To remove from  registration by means of a  post-effective  amendment
   any of the securities being registered which remain unsold at the termination
   of the offering.

                                      II-2


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

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