                LIMITED PARTNERSHIP INTEREST PURCHASE AGREEMENT
                          -----------------------------

     This Limited Partnership  Interest Purchase Agreement (this "AGREEMENT") is
made as of the 28th day of February,  1998,  among Cambridge  Health Services of
Texas, Inc., a Texas corporation (the "BUYER"), Integrated Health Services, Inc.
("IHS"), and Uro-Tech, Ltd., a Texas limited partnership (the "Seller").

                                    PREMISES

     WHEREAS,  the Seller is the owner of an 18%  limited  partnership  interest
(the "Limited Partnership Interest") in Southwest  Lithotripter  Partners,  Ltd.
("Southwest"), a Texas limited partnership; and

     WHEREAS, Buyer wishes to acquire Seller's Limited Partnership Interest from
the Seller,  and the Seller wishes to sell the Limited  Partnership  Interest to
Buyer, in accordance with the terms and conditions hereinafter set forth; and

     WHEREAS, Buyer is a wholly owned subsidiary of IHS; and

     NOW,  THEREFORE,  in  consideration  of the premises and for other good and
valuable  consideration,   the  receipt  and  sufficiency  of  which  is  hereby
acknowledged  by the parties  hereto,  Seller,  IHS and Buyer,  intending  to be
legally bound, agree as follows:

          ARTICLE I: SALE AND PURCHASE OF LIMITED PARTNERSHIP INTEREST

     1.1 SALE AND PURCHASE OF LIMITED PARTNERSHIP INTEREST. Subject to the terms
and conditions of this Agreement, Buyer hereby acquires from the Seller, and the
Seller hereby sells,  assigns,  transfers and conveys to Buyer,  Seller's right,
title and  interest in or to the  Limited  Partnership  Interest  and all rights
arising  out of the  Limited  Partnership  Interest  (the  "Rights"),  including
without  limitation,  all rights to distributions from Southwest (whether or not
currently due or hereafter arising),  and all rights to Seller's Capital Account
(as such term is  defined  in the First  Restatement  of  Agreement  of  Limited
Partnership of Southwest (the "Limited  Partnership  Agreement")).  Concurrently
herewith Seller is delivering a Limited Partnership Interest Transfer Instrument
to Buyer.







                           ARTICLE II: PURCHASE PRICE

     2.1  PURCHASE PRICE.

          Amount and Payment.  Seller hereby  acknowledges  its receipt from the
Buyer of the purchase price (the "Purchase  Price") for the Limited  Partnership
Interest in the amount of SIX HUNDRED THIRTY THOUSAND DOLLARS ($630,000) payable
by the delivery of Nineteen  Thousand Seven Hundred (19,700) newly issued shares
(as may be adjusted, the "IHS Shares"), par value $.001 per share, of Integrated
Health Services,  Inc. ("IHS Stock") subject to  re-calculation  as set forth in
Section 3.1(c) below.

                             ARTICLE III: IHS STOCK

     3.1  IHS STOCK.  All of the IHS Shares are being  delivered  in  accordance
with the following:

          (a) SHARE VALUE.  The number of shares of IHS Stock issued pursuant to
Section 2.1 has been calculated based upon a price per share of such stock equal
to the average  closing NYSE price of such stock for the thirty (30) trading day
period  immediately  preceding the Closing Date, and  certificates  representing
such shares of IHS Stock shall be delivered to Seller  within three (3) business
days of the date hereof. The parties agree that such per share price is $31.98.

          (b) REGISTRATION RIGHTS. IHS shall use its best efforts to cause to be
prepared  and filed  within  fifteen (15)  calendar  days of the date hereof,  a
registration  statement for the  registration  under the  Securities Act of 1933
(the  "SECURITIES  ACT") of the IHS  Stock  issued to  Seller  pursuant  to this
Agreement;  provided,  in any event, IHS shall use its best efforts to cause the
registration  statement  to be  declared  effective  by  May  1,  1998.  If  the
registration statement is not reviewed by the Securities and Exchange Commission
(the  "COMMISSION"),  IHS  shall use its  reasonable  best  efforts  to have the
registration  statement  declared  effective by the Commission and to deliver to
Buyer the final  prospectus  within  fourteen (14) days of the date IHS receives
notice from the commission  that it will not review the  registration  statement
and IHS shall maintain the  effectiveness of such  registration  statement for a
period of one (1) year  following  the date on which it becomes  effective  (the
"REGISTRATION  DATE"), or until Seller shall not own any of the IHS Stock issued
pursuant to this Agreement, whichever shall occur first.

          (c) SHARE  ADJUSTMENT.  For purposes hereof,  the "SHARE VALUE AMOUNT"
shall mean  $630,000;  provided that, if the Share  Adjustment  Date (as defined
below) shall not occur by May 1, 1998,  the Share Value Amount shall increase by
an amount equal to the amount of the interest that would have accrued thereon at
an annual  rate  (compounded  daily) of eight  percent  (8%)  during  the period
commencing on May 2, 1998 and ending on the Share Adjustment Date. Promptly, and
in any event,  within three (3) business  days,  following the Share  Adjustment
Date, the number of shares of IHS Stock  deliverable as the Purchase Price shall
be  re-calculated  (the "ADJUSTED SHARE COUNT") to the extent  necessary so that
such shares will have an aggregate value (the "RECALCULATED VALUE") equal to the
Share Value Amount  based upon the average  closing NYSE price for IHS Stock for
the 30-trading day period  immediately  preceding the Share  Adjustment Date. If
the Adjusted  Share Count exceeds the number of shares of IHS Stock issued as of
the Closing


                                       2





Date (the "CLOSING DATE SHARE  COUNT"),  IHS promptly  shall deliver over to the
Seller an  additional  number of shares of IHS Stock as shall have a value equal
to the amount of such excess (using the  Recalculated  Value for determining the
number of such shares of IHS Stock to be delivered),  and such additional shares
shall be included in the  aforementioned  registration  statement  by means of a
post-effective  amendment  thereto.  If the Closing Date Share Count exceeds the
Adjusted Share Count,  Seller shall promptly  return to IHS the number of shares
of IHS Stock  having a value equal to the amount by which the the  Closing  Date
Share Count exceeds the Adjusted Share Count (using the  Recalculated  Value for
determining  the number of shares of IHS Stock to be  delivered).  For  purposes
hereof,  "SHARE  ADJUSTMENT  DATE"  shall  mean the first to occur  of:  (x) the
Registration  Date and (y) the date on which such IHS Shares become  saleable in
accordance  with Rule 144  promulgated  pursuant  to the  Securities  Act ("RULE
144"). If any IHS Shares are transferred by Seller prior to the Share Adjustment
Date,  appropriate  adjustments shall be made to exclude the amount of the Share
Value Amount allocable to such transferred shares from the adjustments  required
by this subsection (c).

          (d) REGISTRATION  EXPENSES.  IHS shall bear all of the expenses of IHS
related to such  registration and incident to IHS's performance of or compliance
with this Article III including,  without  limitation,  the fees and expenses of
its  counsel,  accountants  and any other  person  retained  by IHS,  all of its
messenger  and delivery  expenses and fees and all of its other costs,  fees and
expenses  incident to the preparation,  printing,  registration and filing under
the  Securities  Act  of the  registration  statement  and  all  amendments  and
supplements   thereto,  the  cost  of  furnishing  copies  of  each  preliminary
prospectus,  each final  prospectus and each amendment or supplement  thereto to
underwriters,  dealers  and  other  purchasers  of IHS  Stock  and the costs and
expenses   (including  fees  and  disbursements  of  its  counsel)  incurred  in
connection  with  the  qualification  of IHS  Stock  under  the Blue Sky laws of
various jurisdictions.  IHS, however, shall not be required to pay underwriter's
or brokerage discounts, commissions or expenses, or to pay any costs or expenses
arising  out  of  Seller's  or any  transferee=s  failure  to  comply  with  its
obligations under this Article III.

          (e)  REGISTRATION  PROCEDURES.  In  connection  with the  registration
rights  granted to the Seller with respect to the IHS Shares as provided in this
Section 3.1, IHS covenants and agrees as follows:

               (i) At IHS's  expense,  IHS will  file with the  Commission  such
amendments and post-effective amendments to the registration statement as may be
necessary  to keep the  registration  and  qualification  under this Section 3.1
effective (and in compliance  with the Securities  Act) and will take such other
actions as may be necessary or appropriate  with respect  thereto for so long as
Seller  owns any of the IHS Stock  except to the extent that an  exemption  from
registration may be available.  IHS will immediately  notify Seller, at any time
when a prospectus relating to a registration statement under this Section 3.1 is
required to be delivered under the Securities Act, of the happening of any event
known to IHS as a result of which the prospectus  included in such  registration
statement, as then in effect, includes an untrue statement of a material fact or
omits to state any material fact  required to be stated  therein or necessary to
make the statements  therein not misleading in light of the  circumstances  then
existing.


                                       3





               (ii) IHS shall furnish Seller with such number of prospectuses as
shall reasonably be requested.

               (iii) IHS shall take all  necessary  action which may be required
in qualifying or registering IHS Stock included in a registration  statement for
offering  and sale  under  the  securities  or Blue Sky laws of such  states  as
reasonably are requested by Seller,  provided that IHS shall not be obligated to
qualify as a foreign  corporation or dealer to do business under the laws of any
such jurisdiction.

               (iv) The information included or incorporated by reference in the
registration  statement filed pursuant to this Section 3.1 will not, at the time
any such registration statement becomes effective,  contain any untrue statement
of a material  fact,  or omit to state any material  fact  required to be stated
therein as necessary in order to make the  statements  therein,  in light of the
circumstances under which they were made, not misleading or necessary to correct
any  statement  in any  earlier  filing of such  registration  statement  or any
amendments thereto. IHS shall, as soon as practicable, notify the Seller, at any
time when a prospectus relating to such registration statement is required to be
delivered under the Securities Act, of the happening of any event as a result of
which  the  prospectus  contained  in such  registration  statement,  as then in
effect,  includes an untrue  statement  of  material  fact or omits to state any
material fact required to be stated  therein or necessary to make the statements
therein not  misleading in the light of the  circumstances  then existing and at
the request of the Seller prepare and furnish to the Seller a reasonable  number
of  copies of a  supplement  to or an  amendment  of such  prospectus  as may be
necessary so that, as thereafter  delivered to the purchaser of such IHS Shares,
such prospectus  shall not include any untrue statement of material fact or omit
to state a material fact required to be stated  therein or necessary to make the
statements therein, in light of the circumstances under which they are made, not
misleading. The registration statement will comply in all material respects with
the provisions of the Securities Act and the rules and regulations thereunder.

          (f) INDEMNIFICATION.

               (i) IHS, without  limitation as to time, shall indemnify  Seller,
any successors and assigns and the officers,  directors, agents and employees of
each of them, and each person, if any, who controls Seller within the meaning of
Section 15 of the Securities Act or Section 20(a) of the Securities Exchange Act
of 1934 ("EXCHANGE  ACT") and the officers,  directors,  agents and employees of
such controlling person, against all losses, claims, damages, liabilities, costs
(including  all  expenses  reasonably  incurred in  investigating,  preparing or
defending against any claim whatsoever) and expenses (collectively, "Losses") to
which any of them may become subject under the Securities  Act, the Exchange Act
or any other statute, common law or otherwise,  arising out of or based upon any
untrue  statement or alleged  untrue  statement of a material fact  contained in
such registration  statement (and any prospectus  contained therein) executed by
IHS or based upon written information furnished by IHS filed in any jurisdiction
in order to qualify IHS Stock under the  securities  laws  thereof or filed with
the  Commission,  any  state  securities  commission  or  agency,  NYSE  or  any
securities exchange; or the omission or alleged omission therefrom of a material
fact required to be stated therein or necessary to make the statements contained
therein not  misleading,  unless such statement or omission was made in reliance
upon and in  conformity  with  written  information  furnished  to IHS by Seller
expressly for use in such registration statement, any


                                       4





amendment or supplement  thereto or any application,  as the case may be. If any
action is  brought  against  Seller or any  controlling  person of Seller or any
officer,  director,  agent or employee of Seller or of such  controlling  person
(collectively,  the "SELLER INDEMNIFIED PARTIES" and each, a "SELLER INDEMNIFIED
PARTY") in respect of which indemnity may be sought against IHS pursuant to this
subsection  3.1(e)(iv),  the Seller  Indemnified  Party shall within thirty (30)
days after the receipt thereby of a summons or complaint,  notify IHS in writing
of the  institution  of such  action and IHS shall  assume  the  defense of such
actions,  including the  employment  and payment of fees and expenses of counsel
(reasonably  satisfactory to the Seller Indemnified Party);  provided,  however,
that the failure to so notify IHS will not relieve  IHS from any  obligation  or
liability  except to the extent that IHS has been prejudiced  materially by such
failure.  The  Seller  Indemnified  Party  shall have the right to employ its or
their own counsel in any such case,  but the fees and  expenses of such  counsel
shall  be at  the  expense  of the  Seller  Indemnified  Party  unless  (A)  the
employment  of such  counsel  shall  have been  authorized  in writing by IHS in
connection  with the defense of such action,  or (B) IHS shall not have employed
counsel  to have  charge  of the  defense  of such  action,  or (C) such  Seller
Indemnified  Party shall have  reasonably  concluded  that there may be defenses
available  to it or them  which  are  different  from  or  additional  to  those
available  to IHS (in which  case,  IHS  shall not have the right to direct  the
defense of such  action on behalf of the Seller  Indemnified  Party),  in any of
which  events  the fees and  expenses  of not more than one  additional  firm of
attorneys  for such Seller  Indemnified  Party shall be borne by IHS.  Except as
expressly  provided in the  previous  sentence,  in the event that IHS shall not
previously  have assumed the defenses of any such action or claim,  and if it is
not otherwise  required to so hereunder,  IHS shall not  thereafter be liable to
any Seller  Indemnified Party in investigating,  preparing or defending any such
action or claim and if it is not  otherwise  required  to do so  hereunder.  IHS
agrees  promptly  to notify  Seller of the  commencement  or any  litigation  or
proceedings against IHS or any of its officers, directors or controlling persons
in  connection  with  the  resale  of IHS  Shares  or in  connection  with  such
registration statement.

               (ii)  The  Seller  of  IHS  Shares  to  be  sold  pursuant  to  a
registration statement,  and its successors and assigns, shall indemnify IHS, or
any officer,  director, agent or employee of Buyer or of such controlling person
(collectively,  the "BUYER  INDEMNIFIED  PARTIES") and each a "BUYER INDEMNIFIED
PARTY"  against any Losses to which they may become subject under the Securities
Act, the Exchange Act or any other statute, common law or otherwise, arising out
of or based  upon any  untrue  statement  of a material  fact  contained  in the
registration  statement,  prospectus or preliminary prospectus or arising out of
or based upon any omission of a material fact  required to be stated  therein or
necessary to make the statements therein not misleading, to the extent, but only
to the extent,  that such untrue  statement  or  omission  is  contained  in any
information  so furnished in writing by Seller to IHS  expressly for use in such
registration  statement  or  prospectus  and  was  relied  upon  by  IHS  in the
preparation   of  such   registration   statement,   prospectus  or  preliminary
prospectus.  In no event will the  liability  of Seller  hereunder be greater in
amount than the dollar  amount of the proceeds  (net of payment of all expenses)
received  by  Seller  upon  the  sale  of the  IHS  Shares  giving  rise to such
indemnification obligation.

          (g) CONTRIBUTION.  If the indemnification provided for in this Section
3.1 is unavailable to an indemnified party under Section 3.1(f)(i) or 3.1(f)(ii)
hereof in  respect  of any Losses or is  insufficient  to hold such  indemnified
party harmless, then each applicable indemnifying


                                       5





party,  in lieu of  indemnifying  such  indemnified  party,  will,  jointly  and
severally, contribute to the amount paid or payable by such indemnified party as
a result of such Losses,  in such  proportion as is  appropriate  to reflect the
relative fault of the  indemnifying  party or indemnifying  parties,  on the one
hand,  and such  indemnified  party,  on the other hand, in connection  with the
actions,  statements  or omissions  that  resulted in such Losses as well as any
other relevant equitable considerations. The relative fault of such indemnifying
party or indemnifying  parties,  on the one hand, and such indemnified party, on
the other hand, will be determined by reference to, among other things,  whether
any action in question,  including any untrue or alleged  untrue  statement of a
material fact or omission or alleged omission of a material fact, has been taken
or made by, or related to information  supplied by, such  indemnifying  party or
indemnified  party,  and the  parties'  relative  intent,  knowledge,  access to
information  and  opportunity  to correct or prevent such  action,  statement or
omission.  The amount  paid or payable by a party as a result of any Losses will
be deemed to include any legal or other fees or expenses  incurred by such party
in connection with any action or proceeding.

     The  parties  hereto  agree  that it  would  not be just and  equitable  if
contribution  pursuant  to this  Section  3.1(g)  were  determined  by pro  rata
allocation or by any other method of allocation  that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding  the  provisions  of this  Section  3.1(g),  Seller  will not be
required  to  contribute  any amount in excess of the amount by which the dollar
amount of the proceeds (net of payment of expenses)  received by Seller upon the
sale of the IHS  Shares  exceed  the  amount of any  damages  which  Seller  has
otherwise  been  required  to pay by reason of such  untrue  or  alleged  untrue
statement  or  omission  or alleged  omission.  No person  guilty of  fraudulent
misrepresentation  (within the meaning of Section 11(f) of the  Securities  Act)
will be  entitled  to  contribution  from any  person who was not guilty of such
fraudulent misrepresentation.

     The indemnity,  contribution and expense  reimbursement  obligations of IHS
hereunder  will be in addition to any liability IHS may otherwise have hereunder
or otherwise. The provisions of this Section 3.1 will survive so long as the IHS
Shares  remain  outstanding,  notwithstanding  any transfer of the IHS Shares by
Seller or any termination of this Agreement.

          (h) NOTICE OF SALE.  Prior to the effective  date of the  registration
statement, if Seller desires to transfer all or any portion of IHS Stock, Seller
will  deliver  written  notice  to IHS,  describing  in  reasonable  detail  its
intention to effect the transfer and the manner of the proposed transfer. If the
transfer is to be pursuant to an effective statement as provided herein,  Seller
will  sell  the  IHS  Stock  in  compliance  with  the  disclosure  therein  and
discontinue  any  offers  and sales  thereunder  upon  notice  from IHS that the
registration  statement  relating  to the IHS  Stock  being  transferred  is not
Acurrent@  until  IHS  gives  further  notice  that  offers  and  sales  may  be
recommenced.  If  Seller  delivers  to  IHS an  opinion  of  counsel  reasonably
acceptable  to IHS and its counsel and to the effect that the proposed  transfer
of IHS Stock may be made without  registration  under the Securities Act, Seller
will be  entitled  to  transfer  IHS Stock in  accordance  with the terms of the
notice and opinion of their counsel.


                                       6





          (i) MISCELLANEOUS. If Seller desires to transfer all or any portion of
IHS Stock,  Seller will deliver written notice to IHS,  describing in reasonable
detail its  intention  to effect  the  transfer  and the manner of the  proposed
transfer.  If  the  transfer  is to be  pursuant  to an  effective  registration
statement as provided herein,  Seller will sell the IHS Stock in compliance with
the disclosure  therein and  discontinue  any offers and sales  thereunder  upon
notice from IHS that the registration  statement relating to the IHS Stock being
transferred  is not  "current"  until IHS gives  further  notice that offers and
sales may be  recommenced.  In the event of any such notice from IHS, IHS agrees
to file  expeditiously  such amendments to the registration  statement as may be
necessary to bring it current during the period  specified in Section 3.1(b) and
to give prompt notice to Seller when the registration statement has again become
current.  If Seller delivers to IHS an opinion of counsel reasonably  acceptable
to IHS and its counsel and to the effect that the proposed transfer of IHS Stock
may be made  without  registration  under the  Securities  Act,  Seller  will be
entitled to transfer  IHS Stock in  accordance  with the terms of the notice and
opinion of their counsel.

          (j)  FURNISH  INFORMATION.  It shall be a condition  precedent  to the
obligations  of the IHS to take any action  pursuant  to this  Article  III that
Seller shall furnish to the IHS such information regarding itself, the IHS Stock
held by it, and the intended  method of disposition of such  securities as shall
be reasonably  required to effect the  registration  of their IHS Stock. In that
connection,  each transferee of Seller shall be required to represent to the IHS
that all such  information  which is given is both  complete and accurate in all
material  respects.  Seller shall deliver to IHS a statement in writing from the
beneficial  owners of such  securities  that it has a bona fide  intent to sell,
transfer  or  otherwise  dispose  of  such  securities.  Each  transferee  will,
severally,  promptly  notify  IHS at any time when a  prospectus  relating  to a
registration  statement covering such transferee's shares under this Section 3.1
is required to be delivered  under the  Securities  Act, of the happening of any
event known to such  transferee as a result of which the prospectus  included in
such registration  statement, as then in effect, includes an untrue statement of
a  material  fact or omits to state  any  material  fact  required  to be stated
therein or necessary to make the  statements  therein not misleading in light of
the statements as then existing.

               (ii) INVESTMENT  REPRESENTATIONS.  All shares of IHS Stock issued
hereunder  have been duly  authorized  and validly issued and are fully paid and
non-assessable shares of IHS. Seller represents and warrants to IHS that the IHS
Stock being issued hereunder is being acquired,  and will be acquired, by Seller
for  investment  for its own  accounts  and  not  with a view to or for  sale in
connection  with any  distribution  thereof within the meaning of the Securities
Act or the applicable  state  securities law; Seller  acknowledges  that the IHS
Stock  constitutes  restricted  securities  under  Rule 144  promulgated  by the
Commission pursuant to the Securities Act, and may have to be held indefinitely,
and  Seller  agrees  that no  shares  of IHS  Stock  may be  sold,  transferred,
assigned,  pledged or  otherwise  disposed of except  pursuant  to an  effective
registration  statement or an exemption from  registration  under the Securities
Act,  the rules and  regulations  thereunder,  and  under all  applicable  state
securities  laws.  Seller has the  knowledge  and  experience  in financial  and
business  matters,  is  capable  of  evaluating  the  merits  and  risks  of the
investment, and is able to bear the economic risk of such investment. Seller has
had the  opportunity  to make inquiries of and obtain from  representatives  and
employees  of IHS such  other  information  about IHS as it deems  necessary  in
connection with such investment.


                                       7





               (iii) LEGEND.  It is understood that, prior to sale of any shares
of IHS Stock  pursuant to an effective  registration  pursuant to subsection (b)
above,  the  certificates  evidencing  such  shares of IHS Stock  shall bear the
following  (or a  similar)  legend  (in  addition  to any  legends  which may be
required in the opinion of IHS's counsel by the  applicable  securities  laws of
any  state),  and  upon  sale  of such  shares  pursuant  to  such an  effective
registration,  new certificates shall be issued for the shares sold without such
legends except as otherwise required by law:

          THE SHARES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN REGISTERED
          UNDER THE  SECURITIES  ACT OF 1933.  THE SHARES HAVE BEEN ACQUIRED FOR
          INVESTMENT AND MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE
          OF AN  EFFECTIVE  REGISTRATION  STATEMENT  FOR THESE  SHARES UNDER THE
          SECURITIES  ACT OF 1933 OR AN OPINION OF THE  COMPANY=S  COUNSEL  THAT
          REGISTRATION IS NOT REQUIRED UNDER SAID ACT.

               (i)  CERTAIN   TRANSFEREES.   Prior  to  the  effective  date  of
registration of the IHS Shares,  no transferee  shall transfer any IHS Shares to
any person or entity unless such  transferee  shall have agreed in writing to be
bound by the provisions applicable to Seller under this Article III.

        ARTICLE IV: REPRESENTATIONS AND WARRANTIES OF THE BUYER AND IHS

     The Buyer and IHS hereby represent and warrant to the Seller as follows:

     4.1 ORGANIZATION AND STANDING OF THE BUYER.  Each of the Buyer and IHS is a
corporation duly organized, validly existing and in good standing under the laws
of its state of  incorporation,  and it has the power and  authority  to own the
property and assets now owned by it and the Limited Partnership  Interest and to
conduct the  business  presently  being  conducted  by it and to enter into this
Agreement and each of the Buyer/IHS  Transaction  Documents (as defined below in
Section 4.2) to which it is a party and to perform its obligations hereunder and
thereunder.

     4.2 AUTHORITY.  Each of the Buyer and IHS has the full corporate  power and
