                                WARRANT AGREEMENT
                                -----------------

     WARRANT  AGREEMENT  dated as of October 21,  1997,  executed by  INTEGRATED
HEALTH SERVICES,  INC., a Delaware corporation (the "Company"),  for the benefit
of Stephen P. Griggs (the "Holder").

     The  Company  and the  Holder  wish to set forth  the terms and  conditions
whereby  the  Holder  will have the option to  purchase  shares of the $.001 par
value common stock of the Company (the "Stock").  Accordingly,  in consideration
of the mutual  covenants  and  agreements  contained  herein and in that certain
Employment  Agreement (the "Employment  Agreement")  dated as of the date hereof
between RoTech Medical Corporation, a subsidiary of the Company, and the Holder,
and  intending to be legally  bound  hereby,  the Company and the Holder  hereby
agree as follows:

     1. Grant of the Warrant.  Subject to the terms and  conditions set forth in
this  Agreement  and any  adjustment  required  by Section 6 below,  the Company
grants to Holder the warrant  (the  "Warrant")  to  purchase  all or any part of
750,000  shares of the Stock (the  "Warrant  Shares") for the purchase  price of
$33.16 per  Warrant  Share.  The Company  shall  cause the Warrant  Shares to be
registered pursuant to an S-3 registration statement.

     2. Term of the Warrant.  The Warrant granted hereunder shall expire at 5:00
p.m., Eastern Standard Time on the date which is on the tenth anniversary of the
date hereof (the "Expiration Time").

     3.  Restrictions  on  Exercisability.   Unless  accelerated,  in  the  sole
discretion of the Company, or except as specifically  provided otherwise herein,
the Warrant will become  exercisable  in accordance  with the following  vesting
schedule:  the Warrant shall become  exercisable  with respect to twenty percent
(20%) of the  Warrant  Shares on October 22 of each  year,  commencing  in 1998,
until the  Warrant  has become  exercisable  with  respect to all of the Warrant
Shares;  provided,  however,  that if Holder  shall die  during  the term of his
employment with the Company, or if a Change of Control (as hereinafter  defined)
shall occur, the Warrant shall become fully exercisable.  For purposes hereof, a
"Change of  Control"  of the  Company  shall mean the  occurrence  of any of the
following  events:  (a) any party or two or more parties acting in concert shall
have acquired beneficial  ownership,  directly or indirectly,  of, or shall have
acquired by  contract or  otherwise,  or shall have  entered  into a contract or
arrangement that, upon consummation, will result in its or their acquisition of,
control  over,  Stock of the Company  representing  25% or more of the  combined
voting power of all Stock of the  Company,  or (b) during any period of up to 24
consecutive  months,  commencing  after the date hereof,  individuals who at the
beginning of such 24-month  period were directors of the Company  (together with
any new director  whose  election by the  Company's  Board of Directors or whose
nomination for election by the Company's  shareholders was approved by a vote of
at least  fifty-one  percent  (51%) of the  directors  then  still in office who
either were directors at the beginning





of such period or whose  election or nomination  for election was  previously so
approved) cease to constitute a majority of the directors of the Company then in
office. As used herein,  "beneficial  ownership" shall have the meaning provided
in Rule 13d-3  promulgated  pursuant to the Securities  Exchange Act of 1934, as
amended.

     4.  Exercise  of the  Warrant.  Subject  to the  restrictions  set forth in
Section 3 above,  the Holder may exercise the Warrant with respect to all or any
portion  of the  Warrant  Shares at any time or from  time to time  prior to the
Expiration  Time by  tendering  to the Company  payment in full of the  purchase
price for the Warrant Shares then being  purchased  together with written notice
to the Company of such exercise that sets forth the following, as applicable:

          (a) if not yet  registered  as set  forth in  paragraph  1  above,  an
acknowledgment  that the Warrant  Shares are being  purchased for investment and
not for  distribution  or resale (other than a distribution  or resale which, in
the  opinion of counsel  reasonably  satisfactory  to the  Company,  may be made
without  violating the provisions of the Securities Act of 1933, as amended (the
"Act"), or any other applicable federal or state securities laws); and

          (b) if not yet  registered  as at  forth  in  paragraph  1  above,  an
acknowledgment  that Holder  understands that the Warrant Shares are "restricted
securities"  within the meaning of Rule 144  promulgated  by the  Securities and
Exchange Commission,  that the Warrant Shares have not been registered under the
Act or any other  applicable  federal or state  securities laws and must be held
indefinitely  unless  they are  subsequently  registered  under such Act and all
applicable laws or an exemption from  registration is available  therefrom,  and
that the Company is under no obligation to register the Warrant Shares under the
Act or any other  applicable  securities  laws or to take any action which would
make available to the Holder any exemption from such registration.

               The  Company   shall  issue  a  stock   certificate   bearing  an
appropriate  legend,  if applicable,  representing the Warrant Shares then being
purchased  upon the actual receipt by the Company of any such written notice and
payment; provided,  however, that if the listing,  registration or qualification
of the Warrant Shares then being purchased upon any securities exchange or under
any  federal  or state  law or the  consent  and  approval  of any  governmental
regulatory  body shall be required in  connection  with the  purchase of Warrant
Shares then being  purchased by such Holder,  the Company shall not be obligated
to issue or deliver a certificate  representing  such Warrant  Shares unless and
until such listing, registration,  qualification, consent or approval shall have
been effected or obtained.  Holder shall have no rights as a stockholder  of the
Company with respect to his Warrant Shares then being  purchased  until the date
on which a stock certificate representing such Warrant Shares has been issued to
the Holder.  The Warrant  granted  hereunder  shall  expire with  respect to any
Warrant Shares as to which Holder has not exercised the Warrant on or before the
Expiration Time.

     5. Transfer of the Warrant. The Warrant may be exercised only by the Holder
or by the Holder's heirs, personal representatives and executors in the event of
such Holder's  death,  and neither the Warrant nor any interest or right therein
shall be subject to or liable for any debts,  contracts  or  engagements  of the
Holder  or  be  subject  to   disposition  by  transfer,   alienation,   pledge,
encumbrance,  assignment  or  any  other  means,  whether  such  disposition  be
voluntary or involuntary or by operation of law by judgment,  levy,  attachment,
garnishment or any other legal or equitable proceedings (including bankruptcy).

     6. Adjustment.

          (a) If the number of shares of issued and outstanding Stock changes at
any time on or before the Expiration  Time as a result of any  recapitalization,
stock  split,  stock  dividend or other  change in the capital  structure of the
Company,  the number of Warrant Shares covered by the Warrant shall be increased
or  decreased  in direct  proportion  to such  change in the number of shares of
issued and  outstanding  Stock and the per share  purchase price of such Warrant
Shares shall be adjusted accordingly so that it is the substantial equivalent of
the purchase price prior to such change.

          (b) If the  Company is merged  into,  or  consolidated  with,  another
company, or another company is merged into the Company, or in the case of a sale
or conveyance  to another  company of the property of the Company as an entirety
on or before the Expiration Time, the Company shall provide in the agreement for
such  merger,  consolidation  or sale that the Warrant is fully vested as of the
date that the merger, consolidation or sale is consummated, and the surviving or
new company  shall grant to the Holder  under  substantially  the same terms and
conditions  as are  contained  in this  Agreement  the option to  acquire  for a
purchase  price adjusted as provided in Section 6(a) above that number and class
of shares in the  surviving  or new  company  into which the shares of the Stock
then  subject to this  Warrant  would have been  converted  or  exchanged if the
Warrant  had  been  exercised  prior  to the  effective  date of the  merger  or
consolidation.

     7.  Taxes.  All  amounts  which,  under  federal,  state or local law,  are
required  to be  withheld  from the amount  reportable  as taxable  income  with
respect to the  exercise of this  Warrant  shall be so withheld by the  Company.
Whenever the Company  proposes or is required to issue or transfer shares of the
Stock hereunder,  the Company shall have the right to require Holder to remit to
the  Company  an  amount  sufficient  to  satisfy  any  federal,  state or local
withholding  tax  requirements  prior  to the  delivery  of any  certificate  or
certificates for such shares of the Stock.
