omissions  occurring on or before the Closing Date; (ii) amounts due or that may
become due to Medicare or Medicaid  or any other  health care  reimbursement  or

contemplated  hereby,  Buyer shall  assume and  thereafter  in due course  fully
satisfy:

                           (i)  all operating trade payables, operating expenses
and other  current  liabilities  of Sellers that would be  classified as current
liabilities  ("Current  Liabilities") on a consolidated balance sheet of Sellers
as of the Closing Date prepared in accordance with generally accepted accounting
principles  (except  as  disclosed  on  Schedule  1.2(b)(i))  applied on a basis

satisfied  concurrently with the Closing,  but excluding any current liabilities
arising out of the Excluded NY O2 Services ("Excluded NY 02 Liabilities"); and

                           (ii)     those  obligations  which  arise  under  the
Designated  Contracts  specified  pursuant to Section 1.3 below and  assigned by
Sellers to Buyer,  with  respect to, and only with  respect  to,  services to be
rendered or goods to be supplied or  benefits to be  conferred  to Buyer  solely
after the Closing Date.  Liabilities  under such Designated  Contracts that have
accrued, or the performance of which is due, on or prior to the Closing Date, or
which are in payment or consideration for Excluded Assets, shall remain the sole
responsibility  of  Sellers  except  to  the  extent  same  constitute   Current
Liabilities.




                                        3





                  1.3      Designated Contracts.

                           (a)     As soon as practicable after the date hereof,
but in no event within two (2) business days after the date hereof,  Buyer shall
deliver notice in writing to Sellers designating which, if any, of the Contracts
to which any Seller is a party listed on Schedule 4.7 hereto pursuant to Section
4.7 of this  Agreement  will be assigned to and assumed by Buyer  (collectively,
the  "Designated  Contracts").  If within  said period of time Buyer fails to so
deliver notice to Sellers,  Buyer will be deemed to have  designated all of said
Contracts;  provided  however,  that  in no  event  will  any of  the  Contracts
described  on Schedule  4.17 below or Schedule  4.7(b)(ix)  below be included as
Designated Contracts.  To the extent Buyer makes (or is deemed to have made) any
such  designation,  Sellers shall at Closing be obligated to assign all of their
right,  title and interest  under such  Designated  Contracts to Buyer and Buyer
shall  assume the  obligations  accruing  after  Closing  under such  Designated
Contracts to the extent provided in Section 1.2 above.

                           (b)      Immediately  after notice  of the Designated
Contracts by Buyer,  each Seller will use its best efforts and shall  diligently
proceed to obtain any consents of any parties necessary to permit the assignment
of the Designated  Contracts.  If any Designated  Contract is not assignable and
the  parties  to any  Designated  Contract  fail or  refuse  to  consent  to any
assignment  on or before the  Closing  Date,  Buyer shall have no  liability  to
assume any such Designated  Contract,  and if such Designated Contract shall not
be a Provider  Contract  (as defined in Section  4.7(b)(vi)  below) and shall be
material to the Business,  Buyer shall be permitted to terminate  this Agreement
in accordance with Article XI hereof.

                  1.4 Designated  Related Contracts;  Other Designated  Provider
Contracts. As soon as practicable after the date hereof, each Seller will notify
or, if  applicable,  provide a form of consent of (in each case, in a writing in
form and  substance  acceptable  to IHS) each  nursing  home,  hospital or other
facility and each licensed professional corporation that is a party to a Related
Contract or other Provider  Contract (as such terms are  hereinafter  defined in
Section 4.7 below) that is a Designated Contract ("Designated Related Contracts"
and  "Designated   Provider   Contracts",   respectively)  that  the  applicable
Designated  Related  Contract  or  Designated  Provider  Contract  with,  or the
management of the  provider(s) of Rehab  Services  and/or O2 Services to, as the
case may be, such  nursing home or hospital or other  facility or such  licensed
professional  corporation  will be  assigned  to  Buyer,  a  subsidiary  of IHS,
effective  at the  Closing.  If at least  fourteen  (14) days shall have elapsed
since the date on which a notice (as set forth  above) is received by a party to
a Related  Contract  or a Provider  Contract  (which  Contract  does not require
consent to the assignment to Buyer) and no termination or threatened termination
of such  Contract  shall  occur prior to Closing,  then such  Contract  shall be
deemed to qualify as  effectively  assigned to Buyer for purposes of Section 1.5
hereof.  Sellers shall not be obligated to provide the notice or form of consent
as required  above with  respect to a  Designated  Provider  Contract if Sellers
obtain the  written  consent (in form and  substance  reasonably  acceptable  to
Buyer)  on or  prior to the  Closing  Date  from  each  applicable  party to the
Designated  Provider  Contract  to the  assignment  to Buyer of said  Designated
Provider Contract or the written

                                        4





acknowledgment  (in form and  substance  reasonably  acceptable  to Buyer) on or
prior to the Closing from each party to the  Designated  Related  Contract  that
Buyer, a subsidiary of IHS, will become the manager of the  applicable  provider
under such Designated Related Contract. Sellers will promptly notify IHS if they
become aware or receive any written or oral notice (directly from any applicable
nursing home, hospital or other facility or licensed  professional  corporation,
or  indirectly  from any  provider  or  otherwise)  of the actual or  threatened
termination of any Designated Related or any other Designated Provider Contract.

                  1.5 Termination of Provider  Contracts and Related  Contracts.
For  purposes of this Section  1.5, a  Designated  Provider  Contract or Related
Contract shall be deemed  "Matured" if it shall have been in effect for at least
sixty (60) days on the Closing  Date.  If, after the date hereof and on or prior
to Closing,  Sellers are unable to assign to Buyer Matured  Designated  Provider
Contracts and Matured  Designated  Related  Contracts (none of which  Designated
Provider  Contracts  and  Designated  Related  Contracts  shall be terminated or
subject to threatened  termination),  that  generate  aggregate  annualized  net
revenues to Sellers  measured as of the Closing Date equal to at least  fourteen
million  four  hundred  thousand  dollars  ($14,400,000),  then  Buyer  shall be
permitted to terminate this Agreement in accordance with Article XI hereof.  For
purposes  of  this  Agreement,  annualized  net  revenues  to a  Seller  for any
Designated  Contract or  Designated  Related  Contract  for the 1996 fiscal year
shall be calculated as follows: The daily net revenue to said Seller arising out
of said Designated Contract or Designated Related Contract shall be equal to the
amount of net  revenue  for the period  commencing  on the later to occur of (x)
January  1,  1996,  and (y) the  date  on  which  such  Designated  Contract  or
Designated  Related Contract was executed and delivered,  and ending October 31,
1996, shall be divided by the number of days during such period.  The annualized
net revenue  shall be equal to the daily net revenue  calculated  in  accordance
with the  preceding  sentence  multiplied by three hundred and sixty five (365);
provided,  however,  that no  revenues  generated  by the  South  Shore  Home or
Woodbridge Nursing Pavillion, Ltd. contracts shall be included.

                  1.6     02 Services in New York; Southshore and Central Island
Management Agreements.

                           (a)      Notwithstanding  anything  to  the  contrary
contained in this Agreement,  Buyer shall not assume, and shall not be assigned,
any Contracts,  obligations  or  liabilities  with respect to O2 Services in the
State of New York  ("Excluded  NY O2  Services"),  except as expressly  provided
below in subsection (b) (ii) below.

                           (b)      (i)     The Group has an  understanding with
Southshore Health Center, 275 West Merrick Road,  Freeport,  New York 11520 (the
"Southshore Home") pursuant to which Rehab 02 (or its successors and assigns) is
to provide management services for the respiratory therapists at such facilities
in  consideration  for a management fee of  approximately  $10,000 per month and
with Central  Island  Nursing Home,  825 Old Country Road,  Plainview,  New York
11803 (the "Central Island Home") pursuant to which Rehab (or its successors and
assigns) is to provide management services for the rehabilitation  therapists at
such facilities in consideration  for a management fee of approximately  $10,000
per month.

                                        5





                                    (ii)    (A)       If within thirty (30) days
after the Closing  Date,  Buyer shall not be assigned and shall not enter into a
written  Management  Agreement  with the Southshore  Home to provide  management
services for the respiratory  therapists at such facility in the form of Exhibit
1.6(b)(ii) (a "Southshore Management  Agreement"),  then Buyer shall be entitled
to a reduction in the  Purchase  Price equal to Five  Hundred  Thousand  Dollars
($500,000),  which amount shall be paid to Buyer out of the Escrow  Deposit upon
demand. If there shall be insufficient shares of IHS Stock in the Escrow Deposit
to cover such $500,000  payment,  the Group shall pay any deficiency to Buyer on
demand.  At the time  that any such  Southshore  Management  Agreement  shall be
assigned to Buyer or executed by Buyer, Sellers shall be deemed automatically to
have  represented  and warranted as of such date that:  (aa) they shall not have
taken  any  action  or  omitted  to take any  action  in  connection  with  such
assignment  or  execution  that  is  not  in  compliance   with  all  applicable
Governmental Requirements; (bb) each representation and warranty that they would
have made pursuant to Section 4.7 hereof had the Southshore Management Agreement
been in effect on the date  hereof  and been  deemed a  Contract  ; and (cc) the
obligations  set forth  under  Sections  B.1.,  B.6.  and D.1 of the  Southshore
Management  Agreement  have  been  satisfied  in  full,  or in the  case  of the
obligations  set forth under  Sections  B.1. and B.6,  Sellers have no reason to
believe,  after  reasonable  investigation,  that Buyer  shall not be capable of
timely and properly satisfying such obligations in full. No Buyer Indemnitee (as
such term is defined in Section  10.2(a))  shall be entitled to  indemnification
for a breach of any  representation  or  warranty  made  pursuant to this clause
(ii)(A)  except to the extent the amount of the claim shall exceed the amount of
any purchase price reduction made in accordance with this clause (ii).

                                            (B) If there  shall be a  Southshore
Management Agreement and it shall be terminated (other than a termination by the
Southshore  Home for cause as  provided  in  Paragraph  F(2) of such  Management
Agreement,  or a  termination  by Buyer  other  than for  cause as  provided  in
Paragraphs F(2) or F(3) of such Management Agreement) prior to the date which is
six months  after its  commencement  date,  then Buyer  shall be  entitled  to a
reduction  in  the  Purchase  Price  equal  to  Five  Hundred  Thousand  Dollars
($500,000)  less the amount of net income  (determined in accordance  with GAAP)
earned by Buyer under such Management  Agreement,  which amount shall be paid to
Buyer out of the Escrow  Deposit  upon  demand.  If there shall be  insufficient
shares of IHS Stock in the Escrow  Deposit to cover such $500,000  payment,  the
Group shall pay any deficiency to Buyer on demand.

                                            (C)   If there shall be a Southshore
Management  Agreement  and  it  shall  not be  terminated  (or  if it  shall  be
terminated  by the  Southshore  Home for cause as provided in Paragraph  F(2) of
such Management Agreement) by notice given prior to the date which is six months
after its  commencement  date (the  "Southshore  Contingency")  and the  Central
Island Contingency (defined below) shall have been satisfied, then Sellers shall
be entitled to receive One Hundred Fifty Thousand  Dollars  ($150,000)  from the
Escrow Deposit upon demand.


                                        6



                                    (iii)   (A)      If  within thirty (30) days
after the Closing  Date,  Buyer shall not be assigned and shall not enter into a
written Management  Agreement with the Central Island Home to provide management
services for the physical, occupational or speech therapists at such facility in
the form of Exhibit 1.6(b)(iii) (a "Central Island Management Agreement"),  then
Buyer  shall be  entitled to a  reduction  in the  Purchase  Price equal to Five
Hundred Thousand Dollars ($500,000),  which amount shall be paid to Buyer out of
the Escrow  Deposit upon demand.  If there shall be  insufficient  shares of IHS
Stock in the Escrow Deposit to cover such $500,000 payment,  the Group shall pay
any  deficiency  to Buyer on demand.  At the time that any such  Central  Island
Management  Agreement  shall be assigned to Buyer or executed by Buyer,  Sellers
shall be deemed  automatically to have represented and warranted as of such date
that: (aa) they shall not have taken any action or omitted to take any action in
connection  with such assignment or execution that is not in compliance with all
applicable Governmental Requirements;  and (bb) each representation and warranty
that they would have made pursuant to Section 4.7 hereof had the Central  Island
Management  Agreement  been in  effect  on the date  hereof  and  been  deemed a
Contract;  and (cc) the obligations set forth under Section [B.1., B.6. and D.1]
of the Central  Island  Management  Agreement have been satisfied in full, or in
the case of the obligations set forth under Sections B.1. and B.6,  Sellers have
no reason to believe,  after reasonable  investigation,  that Buyer shall not be
capable of timely and properly  satisfying  such  obligations  in full. No Buyer
Indemnitee   shall  be  entitled  to   indemnification   for  a  breach  of  any
representation  or warranty made pursuant to this clause  (iii)(A) except to the
extent the amount of the claim  shall  exceed the amount of any  purchase  price
reduction made in accordance with this clause (ii).

                                            (B)      If there shall be a Central
Island Management Agreement and it shall be terminated (other than a termination
by the Central Island Home for cause as provided in Section F(2) such Management
Agreement,  or  termination  by Buyer  other  than  for  cause  as  provided  in
Paragraphs F(2) or F(3) of such Management Agreement) prior to the date which is
six months  after its  commencement  date,  then Buyer  shall be  entitled  to a
reduction  in  the  Purchase  Price  equal  to  Five  Hundred  Thousand  Dollars
($500,000)  less the amount of net income  (determined in accordance  with GAAP)
earned by Buyer under such Management  Agreement,  which amount shall be paid to
Buyer out of the Escrow  Deposit  upon  demand.  If there shall be  insufficient
shares of IHS Stock in the Escrow  Deposit to cover such $500,000  payment,  the
Group shall pay any deficiency to Buyer on demand.

                                            (C)      The      "Central    Island
Contingency" means that there shall be a Central Island Management Agreement and
it shall not be terminated  (unless it shall be terminated by the Central Island
Home for cause as provided in Section  F(2) of such  Management  Agreement or by
IHS other than for cause) by notice  given prior to the date which is six months
after its commencement date.

                                    (iv)    If  not  assigned  at  Closing,  any
assignment and assumption of the Southshore Management Agreement and the Central
Island  Management  Agreement  shall  be  made  pursuant  to an  assignment  and
assumption   agreement   in  the  form  of   Exhibit   8.9-2   hereto   (revised
appropriately).  The assignment and assumption shall be accompanied by a Bill of
Sale conveying to Buyer all of each Seller's right, title and interest in and to
all of such Seller's assets that relate to the Management Agreement.

                           ARTICLE II: PURCHASE PRICE

                  2.1  Determination  and Payment of Purchase Price.  Subject to
adjustment as provided in this  Agreement,  the aggregate  purchase  price to be
paid to  Sellers  for the  Assets and their  respective  obligations  under this
Agreement  (the  "Purchase  Price")  shall be EIGHT  MILLION and 00/100  DOLLARS
($8,000,000.00), and which Purchase Price shall be payable as follows:

                           (a)     FIVE MILLION THREE HUNDRED AND 00/100 DOLLARS
($5,300,000) shall be paid at the Closing to Sellers in cash by wire transfer of
immediately  available funds to the account  designated in writing by Sellers at
least one business day prior to the Closing;

                           (b)     TWO MILLION FIFTY THOUSAND AND 00/100 DOLLARS
($2,050,000) shall be paid at the Closing by delivery to Sellers of newly issued
shares of the Common Stock, par value $.001 per share, of IHS (the "IHS Stock"),
based upon the valuation and subject to the terms and  conditions of Section 2.5
below; and

                           (c)     SIX HUNDRED FIFTY THOUSAND AND 00/100 DOLLARS
($650,000)  (the "Escrow  Deposit")  shall be paid by the deposit into an escrow
account as provided in Section 2.4 below of shares of IHS Stock,  based upon the
valuation and subject to the terms and conditions of Section 2.5 below.

                  2.2  Allocation  of  Purchase  Price.  The  Purchase  Price as
adjusted pursuant to this Agreement (and all other capitalizable costs) shall be
allocated  among  the  Sellers  and  with  respect  to each  Seller,  among  the
categories of Assets, as shall be determined by Sellers,  subject to the consent
of Buyer (which consent shall not unreasonably be withheld),  in accordance with
Section 1060 of the Internal Revenue Code of 1986, as amended (the "Code"). Each
of the parties hereto agrees to prepare and file all tax returns (including Form
8594) in a manner consistent with such allocation and to report this transaction
for Federal and state income tax purposes in accordance  with such allocation of
the Purchase Price.

                  2.3      Working Capital Adjustments to the Purchase Price.

                           (a)      For the purposes of this Agreement, "Current
Assets" shall mean the aggregate  amount of all assets of the Sellers that would
be classified as current assets on the consolidated balance sheet of the Sellers
as of the Closing Date  prepared in  accordance  with GAAP,  but  excluding  any
current assets that constitute  Excluded NY O2 Assets,  it being understood that
all Southshore  Receivables shall be included as Current Assets. As used herein,
"Working  Capital"  means the amount by which  Current  Assets  exceeds  Current
Liabilities.

                                        8





                           (b)    At the Closing, Sellers shall deliver to Buyer
the consolidated  balance sheet of Sellers as of the Closing Date,  certified by
the Chief  Financial  Officer  of each  Seller to be his or her best good  faith
estimate of such  balance  sheet as of the Closing  (the  "Closing  Date Balance
Sheet").  The Closing Date Balance Sheet shall  indicate which of the assets and
liabilities constitute Excluded NY O2 Assets and Excluded NY O2 Liabilities. The
Purchase  Price  payable to the  Sellers  shall be reduced if the  Closing  Date
Balance Sheet discloses that the  consolidated  Working Capital of Sellers as of
the Closing Date (the "Closing Date Working Capital") is less than EIGHT HUNDRED
THOUSAND DOLLARS ($800,000 (the "Minimum Amount").  In such event, the amount of
the Purchase  Price payable to the Sellers at the Closing shall be reduced by an
amount, on a  dollar-for-dollar  basis, equal to the amount by which the Closing
Date Working Capital is less than such Minimum Amount.

                           (c)      Buyer may complete,  at its own  expense,  a
review of the Closing Date Working Capital, and, if it does so, shall deliver to
Sellers its written  report (the  "Working  Capital  Review")  setting forth the
amount of such  Closing  Date Working  Capital as  confirmed  or  determined  in
accordance  with such review.  If Buyer shall not have  completed such a Working
Capital  Review and delivered a copy thereof to Sellers  within ninety (90) days
following the Closing Date, Buyer shall be deemed to conclusively  have accepted
the  determination  of the  Closing  Date  Working  Capital  as set forth on the
Closing Date Balance Sheet, and such determination  shall become final and shall
not be subject to further review, challenge or adjustment,  absent fraud. In the
event that the  Working  Capital  Review is timely  prepared  and  delivered  to
Sellers and it discloses that the Closing Date Working Capital was less than the
lesser of: (x) the Minimum Amount and (y) the amount of the Working  Capital set
forth on the Closing Date Balance  Sheet,  the Purchase Price shall be deemed to
have been  reduced  by the  amount of such  deficiency;  provided,  however,  if
Sellers shall dispute the amount set forth in the Working Capital  Review,  they
shall give notice to Buyer (a "Delay  Payment  Notice")  within thirty (30) days
after delivery to them of the Working Capital Review that the payment  specified
in subsection (d) hereof should not then be made and setting forth in reasonable
detail their objections and the basis therefor,  in which case the parties shall
meet and in good faith attempt to resolve any  disagreements  within thirty (30)
days after  delivery to Buyer of the Delay  Payment  Notice.  If the parties are
unable to resolve such disagreements  within such time period, the disagreements
shall be referred to a "Big Six" accounting firm selected by mutual agreement of
Sellers, on the one hand, and Buyer, on the other hand (or if the parties cannot
agree on such selection,  then a "Big Six" accounting firm, other than KPMG Peat
Marwick  LLP  selected  by  lot)  (the   "Settlement   Accountants"),   and  the
determination  of the  Settlement  Accountants  shall be final  and shall not be
subject to further review, challenge, or adjustment absent fraud. The Settlement
Accountants shall be directed to use their best efforts to reach a determination
not more than forty-five  (45) days after such referral.  The costs and expenses
of the  services  of the  Settlement  Accountants  shall be  borne by the  party
against  whom  the  Settlement  Accountants  shall  rule;  provided  that if the
Settlement Accountants shall not clearly rule against any party, then such costs
and expenses shall be borne equally by Sellers,  on the one hand, and Buyer,  on
the other hand.

                                        9





                           (d)    If the Purchase Price is decreased as provided
in this  Section  2.3,  the amount of the  decrease  shall be paid  promptly  by
Sellers to Buyer.  Such payment shall be made in IHS Stock (valued in accordance
with Section  2.4(c) below) out of the Escrow  Deposit to the extent there shall
be sufficient  shares therefor and any further  deficiency shall be paid in cash
by Sellers.

                           (e)      The parties acknowledge  that   because  the
Purchase Price is payable,  in part, by the delivery of shares of IHS Stock, and
that at least two (2) business days  lead-time is necessary to prepare the stock
certificates,  it may be impractical  to make Purchase Price  adjustments at the
Closing  by  changing  the  number  of  shares  of IHS  Stock  to be  delivered.
Accordingly,  to the extent such  adjustments  can not be made at the Closing by
way of decreasing  the number of shares  delivered,  the parties agree that such
adjustments  will be made by the  reduction  in the  payment of cash at Closing.
Notwithstanding  the  foregoing,  in lieu  of  reducing  the  cash  payments  in
accordance with the foregoing  sentence,  Sellers may elect to instruct  Buyer's
attorneys to hold the stock certificates evidencing the Purchase Price in escrow
pending the  issuance to Sellers of stock  certificate(s)  evidencing  the exact
amount of the Purchase Price.

                  2.4      Escrow Indemnification.

                           (a)   At the Closing, pursuant to an Escrow Agreement
to be executed by the parties in substantially the form and substance of Exhibit
2.4 hereto,  the Escrow  Deposit  shall be  deposited  with an escrow agent (the
"Escrowee")  acceptable  to Buyer and Sellers and shall be held by the Escrowee,
together with all dividends  (stock or cash), if any,  earned  thereon,  and any
interest or income earned thereon in accordance with the Escrow Agreement,  as a
non-exclusive  source of indemnification  from the Sellers for any amount due to
any Buyer  Indemnitee (as such term is  hereinafter  defined) and as a source of
repayment  of any  reduction in the  Purchase  Price  pursuant to Section 1.6 or
Section  2.3 above.  The Escrow  Deposit  shall be deemed to be the  property of
Buyer  unless and until paid to Sellers  pursuant to the Escrow  Agreement.  The
Escrow Deposit (plus all dividends,  if any, earned thereon, and any interest or
income earned thereon in accordance  with the Escrow  Agreement) less any claims
made pursuant to Section 1.6 or Section 2.3 above or for Losses (as such term is
defined  in  Section  10.2(a)  hereof),  and also  less any  amounts  previously
released to Sellers in accordance  with Section 1.6 above,  shall be released to
Sellers on the first  anniversary  of the Closing Date. If any Buyer  Indemnitee
shall  have  asserted  a  claim  to  indemnification  or  for a  Purchase  Price
reduction,  and the amount of such claim shall not have been finally  determined
by the first  anniversary  of the  Closing  Date,  then the amount of the Escrow
Deposit to be  released to Sellers in  accordance  with the  foregoing  sentence
shall be reduced by a reasonable  reserve for such claim as  determined by Buyer
in good faith and set forth in a notice to  Sellers  and the  Escrow  Agent.  If
Sellers  shall  dispute  the amount of such  reserve,  they shall give notice to
Buyer  setting  forth  in  reasonable  detail  their  objections  and the  basis
therefor,  in which case the  parties  shall  meet and in good faith  attempt to
resolve any  disagreements  within  thirty (30) days after  Sellers'  receipt of
notice of the amount of the  reserve.  If the parties are unable to resolve such
disagreements  within such time period,  the disagreements  shall be referred to
the Settlement Accountants,  and the determination of the Settlement Accountants
shall be final and

                                       10





shall not be subject to further review,  challenge,  or adjustment absent fraud.
The Settlement  Accountants shall be directed to use their best efforts to reach
a  determination  not more than  forty-five  (45) days after such referral.  The
costs and expenses of the services of the Settlement  Accountants shall be borne
by the party against whom the Settlement  Accountants shall rule;  provided that
if the  Settlement  Accountants  shall not clearly rule against any party,  then
such costs and expenses shall be borne equally by Sellers,  on the one hand, and
Buyer, on the other hand.

                           (b)   Subject to the limitations set forth in Section
2.5 below  (including  without  limitation,  Sections  2.5 (b) and 2.5(c))  with
respect to the sale of shares of IHS Stock issued pursuant to this Agreement, if
Sellers shall so request, Buyer and IHS shall agree to the sale of shares of IHS
Stock  constituting  all or part  of the  Escrow  Deposit  if the  entire  gross
proceeds  of such sale  shall  become  part of the Escrow  Deposit  and shall be
deposited with the Escrow Agent and held pursuant to the Escrow  Agreement,  and
Buyer and IHS shall have  determined  that a satisfactory  procedure  shall have
been  established  so that at all times  before,  during and after such sale the
escrowed shares of IHS Stock to be sold and said gross proceeds thereof shall be
subject to the sole possession and control of the Escrow Agent and shall be free
and clear of all Liens of third  parties  (other than the Escrow Agent if and as
provided in the Escrow Agreement).

                           (c)      For purposes of determining the value of any
shares of IHS Stock claimed as a source for indemnification,  for Purchase Price
reductions  or for  release of less than all of the shares  held in escrow,  the
Current  Market  Value Per Share shall be used.  For  purposes  hereof  "Current
Market  Value Per Share"  means the  average  closing  New York  Stock  Exchange
("NYSE")  price of IHS Stock for the thirty (30)  business day period  ending on
the date  which is two (2)  business  days  prior to the date on which  such IHS
Stock is to be released from the Escrow pursuant to the Escrow Agreement.

                           (d)      If any shares of IHS Stock constituting  any
part of the Escrow Deposit shall be sold,  the gross  proceeds  thereof shall be
held by the Escrow Agent  pursuant to the terms of the Escrow  Agreement and may
be invested in  accordance  with the mutual  instructions  of Sellers and IHS as
provided in the Escrow Agreement. Any interest or income or dividends paid on or
in respect of all or any part of the Escrow Deposit  ("Escrow  Income") shall be
added to the Escrow  Deposit  and shall be used for the benefit of Sellers or be
paid to Sellers upon release of the balance of the Escrow Deposit.

                           (e)      The costs, fees and expenses of  the  Escrow
Agent shall be borne  equally by Buyer,  on the one hand,  and  Sellers,  on the
other hand.

                  2.5      IHS Stock.

                           (a)    As set forth in Sections 2.1(b) and (c) above,
but subject to Sections  2.3(d) and (e) above,  a portion of the Purchase  Price
equal to TWO MILLION  SEVEN  HUNDRED  THOUSAND AND 00/100  DOLLARS  ($2,700,000)
shall be payable by means of the

                                       11





delivery to Sellers  and the  Escrowee of IHS Stock based upon a price per share
of such stock equal to the  average  closing  New York Stock  Exchange  ("NYSE")
price of such stock for the thirty (30)  business day period  ending on the date
which is two (2) business  days prior to the Closing Date (the  "Initial  Market
Value Per Share").

                           (b)      Resale Limitations.   All sales of IHS Stock
issued pursuant to this Agreement shall be effected solely through Smith Barney,
Inc.,  as  broker,   which  shall  charge  not  more  than  customary  brokerage
commissions,  and sales of such shares shall not at any time, in the  aggregate,
exceed fifty  thousand  (50,000)  shares  during any thirty (30) day period;  it
being  understood  however,  that such  covenant will not apply to shares of IHS
Stock issued  pursuant to the Asset  Purchase  Agreement,  dated as of April 20,
1996,  among  them,  Hospice  of the  Great  Lakes,  Inc.  ("HGL"),  Hospice  of
Integrated Health Services, Inc., IHS and various other shareholders of HGL.

                           (c)      Investment  Representations.   All shares of
IHS Stock to be issued hereunder will be newly issued shares of IHS. Sellers and
the  Members  represent  and  warrant to IHS and Buyer that the IHS Stock  being
issued  hereunder  is being  acquired,  and will be  acquired,  by  Sellers  for
investment  for their  own  accounts  or for the  account  of any  Member or the
Consultant  (as such term is defined in Section 13.1) to whom transfer of any of
such shares is expressly  permitted in accordance with this  Agreement,  and not
with a view to or for sale in connection  with any  distribution  thereof within
the meaning of the Securities Act of 1933, as amended (the "Securities  Act") or
any applicable state  securities law;  Sellers and each Member  acknowledge that
the IHS Stock  constitutes  restricted  securities under Rule 144 promulgated by
the  Securities  and  Exchange  Commission  (the  "Commission")  pursuant to the
Securities  Act,  may  have  to be  held  indefinitely  and  may  not  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 and the rules and regulations thereunder. Sellers and each Member
have the knowledge and experience in financial and business matters, are capable
of evaluating the merits and risks of the  investment,  and are able to bear the
economic  risk of such  investment.  Sellers and each Member have been  provided
with such materials as are generally  provided to  shareholders  of IHS and have
had the  opportunity  to make inquiries of and obtain from  representatives  and
employees  of IHS such other  information  about IHS as they deem  necessary  in
connection with such investment.

                           (d)  Legends.  It is understood that the certificates
evidencing  the 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):

                  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.

                                       12





                           (e)     Transfers.  Upon prior notice to IHS, Sellers
shall be  permitted  to transfer  any of the shares of IHS Stock  acquired by it
pursuant  to this  Agreement  (other  than shares then being held as part of the
Escrow  Deposit)  and the  registration  rights  related  thereto  to any of the
Members,  the Consultant or TRS Protective  Trust,  Trustees David S. Krause and
Ronald Paler,  dated October 23, 1996,  (each a "Transferee") in accordance with
Section 13.1 hereof,  provided  that said  transfer  shall be made in compliance
with all applicable securities laws. As a condition to any such transfer, if IHS
shall  reasonably  so request,  Sellers  shall cause an opinion of legal counsel
(such  opinion  and legal  counsel  to be  reasonably  acceptable  to IHS) to be
delivered  to IHS upon  which IHS and its legal  counsel  may rely to the effect
that such  transfer may be made in  compliance  with all  applicable  securities
laws. Upon such transfer the acquiring  Transferee  shall be deemed to have made
each of the  representations  and  warranties  set forth in subsection (c) above
with respect to himself, herself or itself, as of the date of such transfer, and
he, she or it shall be bound by the  provisions  of this  Agreement  relating to
such transferred shares,  including without  limitation,  the resale limitations
set forth in  subsection  (b) above and all of the  obligations  relating to the
registration  of the shares.  No such transfer shall release any Seller from any
of its obligations under this Agreement  relating to such transferred  shares or
otherwise.

                           (f)      Registration of IHS Stock.

                                    (i)   IHS will use its best efforts to cause
to be prepared, filed and declared effective by the Commission within sixty (60)
days following the Closing Date, a registration  statement for the  registration
under the  Securities  Act of the IHS Stock  issued to Seller  pursuant  to this
Agreement  (including,  without  limitation,  all of  the  shares  of IHS  Stock
constituting   part  of  the  Escrow  Deposit),   and  IHS  shall  maintain  the
effectiveness  of such  registration  statement  for a period  of two (2)  years
following the date on which it becomes  effective,  or for so long as any Seller
(or any  Transferee)  shall own any of the IHS  Stock  issued  pursuant  to this
Agreement,  whichever  shall occur first, in each case except to the extent that
an exemption from registration may be available.  If the number of shares of IHS
Stock constituting the Purchase Price shall be increased pursuant to clause (ii)
below, IHS shall, prior to the effective date, estimate the number of additional
shares and shall use its best efforts to include all of the newly issued  shares
in the  registration  statement.  IHS  shall use its best  efforts  to cause the
shares of IHS Stock to be approved for listing on the NYSE.

                                    (ii)             If, notwithstanding the use
of its best  efforts as  provided  in clause  (i) above,  IHS does not cause the
registration  statement to be prepared,  filed and declared effective within one
hundred and eighty (180) days after the Closing  Date,  then as of the date that
such registration statement shall become effective,  the number of shares of IHS
Stock  constituting  the Purchase  Price shall be adjusted so that the number of
shares  issued to  Sellers  pursuant  to this  Agreement  (including  the shares
constituting the Escrow Deposit) shall have an aggregate fair market value equal
to the amount of the stock portion of the Purchase Price as adjusted pursuant to
this  Agreement  based upon a price per share of such stock equal to the average
closing NYSE price of such stock for the thirty (30)  business day period ending
on the date which is two (2)

                                       13





business  days prior to such  effective  date (the  "Adjusted  Market  Value Per
Share").  Within  five (5)  business  days after such  effective  date IHS shall
deliver notice (the "Adjustment  Notice") to Seller of the Adjusted Market Value
Per Share and the number of shares to be  delivered  by Buyer to Sellers and the
Escrow  Agent (if the  Adjusted  Market  Value Per Share  shall be less than the
Initial  Market Value Per Share) or by Sellers and the Escrow Agent to Buyer (if
the Adjusted  Market  Value Per Share shall be greater  than the Initial  Market
Value Per Share) so as to effect the  adjustment  described in this clause (ii).
The number of shares to be  delivered  or issued,  as the case may be,  shall be
rounded up or down so that no fractional shares need be issued.  Within five (5)
business  days the parties  shall make (and if  applicable,  shall  instruct and
cause the Escrow Agent to make) the delivery of the shares of IHS Stock required
in the Adjustment Notice.

                           (g)      Registration Procedures, etc.  In connection
with the registration rights granted to Sellers with respect to the IHS Stock as
provided in this Section 2.5, IHS agrees as follows:

                                    (i)      IHS will promptly notify Sellers at
any time when a prospectus  relating to a  registration  statement  covering any
Seller's  shares under this  Section 2.5 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,  and, to the extent
required by applicable law, IHS shall promptly  prepare and file with the SEC as
appropriate a supplement or amendment to such  prospectus so that, as thereafter
timely  delivered to the  purchaser of any IHS Stock such  prospectus  shall not
contain an untrue  statement  of a material  fact or omit to state any  material
fact required to be stated therein or necessary to make the  statements  therein
not misleading.

                                    (ii)    IHS shall furnish Sellers with  such
number of  prospectuses as shall  reasonably be requested,  and Sellers agree to
comply  with the  prospectus  delivery  requirements  of the  Securities  Act in
connection with any sale of IHS Stock by it.

                                    (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 Sellers,  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  2.5 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. The

                                       14





registration  statement will comply in all material respects with the provisions
of the Securities Act and the rules and regulations thereunder.  With respect to
sales of IHS Stock sold in  accordance  with the  provisions of this Section 2.5
pursuant to the registration  statement,  IHS shall indemnify  Sellers and their
permitted successors and assigns, and the Transferees,  and each person, if any,
who controls  Sellers  within the meaning of Section 15 of the Securities Act or
Section 20(a) of the Securities  Exchange Act of 1934, as amended (the "Exchange
Act"),  against all loss,  claim,  damage,  expense or liability  (including all
expenses  reasonably  incurred in investigating,  preparing or defending against
any  claim  whatsoever)  to  which  any of them may  become  subject  under  the
Securities Act, the Exchange Act or any other statute,  common law or otherwise,
based upon a sale by them  pursuant to any untrue  statement  or alleged  untrue
statement of a material fact contained in such registration  statement  executed
by IHS or based upon a sale by them pursuant to 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,  NASDAQ, 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 any Seller or any  Transferee  for use in such  registration
statement,  any amendment or supplement thereto or any application,  as the case
may be. If any action is brought against any Seller or any controlling person of
any Seller or any Transferee in respect of which indemnity may be sought against
IHS pursuant to this subsection,  such Seller or such controlling person or such
Transferee  shall within thirty (30) days after the receipt thereof of a summons
or complaint,  notify IHS in writing of the  institution  of such action and IHS
shall assume the defense of such action, including the employment and payment of
reasonable  fees and  expenses  of counsel.  Any Seller or any such  controlling
person or any such  Transferee  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 such  Sellers  or such  controlling  persons or such  Transferee
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
indemnified  party or parties 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 indemnified party or parties), in any of
which  events  the fees and  expenses  of not more than one  additional  firm of
attorneys for Seller,  such  controlling  person and such  Transferees  shall be
borne by IHS and such law firm shall be reasonably  acceptable to IHS. Except as
expressly provided in the previous  sentence,  in the event that any Seller, any
such controlling person or any such Transferee assumes control of the defense of
any such action or claim,  IHS shall not  thereafter be liable to such Seller or
any such controlling  person or such Transferee in  investigating,  preparing or
defending any such action or claim. IHS agrees promptly to notify Sellers of the
commencement  of  any  litigation  or  proceedings  against  IHS  or  any of its
officers,  directors or controlling persons in connection with the resale of IHS
Stock or in connection with such registration  statement. If the indemnification
provided for in this Section 2.5 is held by a court of competent jurisdiction to
be  unavailable  to any  Seller or any  controlling  person of any Seller or any
Transferee with respect to any loss,

                                       15





liability,  claim,  damage or expense  referred  to herein,  then IHS in lieu of
indemnifying  any  Seller  or  any  controlling  person  of  any  Seller  or any
Transferee  hereunder,  shall  contribute  to the amount  paid or payable by any
Seller  or  any  controlling  person  of  such  Seller  or any  such  Transferee
hereunder,  as a result of such  loss,  liability,  claim,  damage,  expense  or
liability in such  proportion as is appropriate to reflect the relative fault of
IHS on the one hand and of such Seller or any controlling  person of such Seller
or any  Transferee  on the  other  hand in  connection  with the  statements  or
omissions which resulted in such loss,  liability,  claim,  damage,  expense, or
liability, as well as any other relevant equitable considerations.  The relative
fault of IHS and of such Seller or any controlling  person of such Seller or any
Transferee shall be determined by reference to, among other things,  whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material  fact relates to  information  supplied by IHS or by such Seller or any
controlling  person of such Seller or any Transferee  and the parties'  relative
intent,  knowledge,  access to information and opportunity to correct or prevent
such statement or omission.

                                    (v)  Sellers and any Transferee who proposes
to sell IHS Stock  pursuant to a  registration  statement,  and its,  his or her
respective successors and assigns, shall severally,  and not jointly,  indemnify
IHS and Buyer,  their  respective  officers,  directors and  advisers,  and each
person,  if any,  who  controls IHS or Buyer within the meaning of Section 15 of
the Securities Act or Section 20(a) of the Exchange Act against all loss, claim,
damage,  expense or liability  (including  all expenses  reasonably  incurred in
investigating,  preparing or defending  against any claim  whatsoever)  to which
they may become subject under the Securities  Act, the Exchange Act or any other
statute,  common law or  otherwise,  insofar as such  losses,  claims,  damages,
expenses  or  liabilities  (or actions in respect  thereof)  arise out of or are
based upon any untrue or alleged untrue statement of any material fact contained
in a  registration  statement,  a  prospectus,  or any  amendment or  supplement
thereto filed by IHS in accordance with this  Agreement,  or arise out of or are
based upon the  omission or alleged  omission to state  therein a material  fact
required to be stated  therein or necessary to make the  statements  therein not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue  statement or omission or alleged  omission was made
in a  registration  statement,  a  prospectus,  or any  amendment or  supplement
thereto  filed  in  accordance  with  this  Agreement  in  reliance  upon and in
conformity  with written  information  furnished  to IHS by the Sellers,  or any
Transferee, or its, his or her respective successors or assigns.

                           (h)      Registration Expenses.    IHS shall bear all
reasonable expenses related to such registration.  Such costs and expenses shall
include, without limitation, the fees and expenses of counsel for IHS and of its
accountants,  all  other  costs,  fees  and  expenses  of  IHS  incident  to the
preparation,  printing,  registration and filing under the Securities Act of the
registration  statement and all amendments and supplements thereto, the fees and
expenses  of one  counsel  to  Sellers  and  the  Transferees  relating  to such
registration, 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 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

                                       16





underwriter's  or brokerage  discounts,  commissions or expenses,  or to pay any
costs  and  expenses  in  excess  in the  aggregate  of  $20,000  for  Blue  Sky
qualifications of Sellers' (and any Transferee's) IHS Stock, or to pay any costs
or expenses  arising out of any Seller's or any  Transferee's  failure to comply
with its obligations under this Section 2.5.

                           (i)      Notice  of  Sale.     Except  for  transfers
permitted under Section 2.5(e), above, if any Seller (or any of its Transferees)
desires to transfer all or any portion of its,  his or her IHS Stock,  it, he or
she will deliver  written  notice to IHS,  describing in  reasonable  detail its
intention to effect the transfer and the manner of the proposed transfer.

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

                  3.1      Time and Place of Closing.

                           (a)   The closing (the "Closing") of the transactions
contemplated  by  this  Agreement  shall  take  place  by  mail  through  escrow
arrangements  satisfactory to the parties hereto on November 8, 1996, or at such
other  time and place upon which the  parties  may agree.  The date on which the
Closing is held is hereinafter referred to as the "Closing Date."

                           (b)      If  prior  to  or  on the Closing Date: each
license  to  operate  the  Business  by  the  state  agency  or  agencies   with
jurisdiction  over the  licensing  of the  Business has not been issued to Buyer
(the  "Required  Approvals");  then,  the Closing  Date  automatically  shall be
extended  until  the date  which is  sixty  (60)  days  after  the date  hereof;
provided, however, that if the Required Approvals are not obtained by such date,
this  Agreement  automatically  shall  terminate,  unless Buyer and Seller shall
mutually  agree to extend said date, and such  termination  shall be governed in
accordance with Article XI herein.

                           (c)      If  prior  to  or on the Closing Date, Buyer
shall have the right to terminate  this Agreement by reason of the occurrence of
any of the events specified in Section 1.3(b) or Section 1.5 above,  then Buyer,
in its sole discretion shall be entitled to extend the Closing Date for up to an
additional  sixty (60) days to provide  time to obtain the consents or approvals
contemplated  thereby.  If prior to or on the Closing Date, Buyer shall have the
right to  terminate  this  Agreement by reason of the  occurrence  of any of the
events specified in Section 1.5 above,  then Sellers,  in their sole discretion,
shall be entitled to extend the Closing Date until November 15, 1996, to provide
time to  obtain  the  consents  or  approvals  or  acknowledgments  contemplated
thereby.

          ARTICLE IV: REPRESENTATIONS AND WARRANTIES OF SELLERS AND THE
          -------------------------------------------------------------
                                     MEMBERS
                                     -------

                  Sellers and the Members hereby jointly and severally represent
and  warrant to Buyer and IHS as provided  in this  Article  IV,  subject to the
following rules of construction and qualification:

                           (a)     Each representation and warranty qualified by
the phrase "to the Group's  Knowledge"  shall be  considered  to be made by each
Seller to its actual knowledge after reasonable investigation and by each Member
to his or her actual knowledge after reasonable investigation; and

                           (b)      To the extent any representation or warranty
is made with  respect to the  status,  affairs,  circumstances  or effect on any
Member  (as  opposed  to on any  Seller),  such  as the  enforceability  of this
Agreement against a Member,  said  representation or warranty shall be deemed to
have been made  individually  (and not  jointly) by each Group  Participant  and
shall be deemed to have been made by each  Member  other  than the Member who is
the subject of such  representation or warranty only to such Member's knowledge;
provided that the foregoing  knowledge  shall not apply to  representations  and
warranties of the Ruby Members with respect to Ruby.

                  4.1      Organization and Standing; Subsidiaries.

                           (a)      Each Seller is a limited  liability  company
duly  organized,  validly  existing and in good  standing  under the laws of the
State of Illinois.  Copies of each such limited liability company's  Certificate

been  delivered  to Buyer,  and are  complete  and  correct.  Each such  limited
liability company has the power and authority to own the property and assets now
owned by it and to conduct the business  presently  being  conducted by it. Each
such limited  liability company is qualified to do business as a foreign limited
liability  company in any state where the ownership of its assets or the conduct
of its business makes such qualification necessary.

                           (b)      Ruby  is  a  limited  liability company duly
organized,  validly existing and in good standing under the laws of the State of
Wisconsin. Copies of its Certificate of Organization and Operating Agreement and
all amendments  thereof to date, have been delivered to Buyer,  and are complete

                           (c)      Except  as  set forth on Schedule 4.1(b), no
Seller has any equity interest or investment in any other  corporation,  limited
liability  company,  partnership,  joint venture or other entity or association.
Schedule 4.1(b) sets forth a complete list of all  subsidiaries,  joint ventures
and  partnerships in which any Seller is the record or beneficial  owner of five
(5%) percent or more of the equity  interest.  All of the issued and outstanding
capital  stock or other  equity  interest  of the  entities,  if any,  listed on
Schedule 4.1(b) hereto is owned of record and  beneficially by the listed Seller
or by one of the listed  wholly-owned  subsidiaries except as listed on Schedule

                  4.2 Authority.  (a) Each Seller has the full limited liability
company power and authority to make, execute, deliver and perform this Agreement
including  all  Schedules  and  Exhibits  hereto,   and  the  other  agreements,
instruments,  certificates  and  documents  required or  contemplated  hereby or
thereby to be executed or delivered by it,  including  without  limitation,  the
Escrow Agreement  (collectively the "Seller  Transaction  Documents") and all of
the  transactions  contemplated  hereby and thereby.  Such execution,  delivery,
performance and consummation  have been duly authorized by all necessary action,
limited liability company or otherwise,  on the part of each Seller, its members
and all necessary  consents of holders of  indebtedness of each Seller have been
obtained.

                           (b)        Each Member has  the full legal  power and
capacity to make,  execute,  deliver and perform this  Agreement  including  all
Schedules  and  Exhibits  hereto,   and  the  other   agreements,   instruments,
certificates  and  documents  required or  contemplated  hereby or thereby to be
executed  or  delivered  by him  or her  ("Member  Transaction  Documents",  and
collectively  with the Seller  Transaction  Documents,  the  "Group  Transaction
Documents"),  and all of the transactions  contemplated hereby and thereby. Such
execution, delivery, performance and consummation have been made in the exercise
of each such  Member's free will and  volition,  and any  necessary  consents of
holders of indebtedness of such Members have been obtained. In the case of Ruby,
such execution, delivery, performance and consummation have been duly authorized
by all necessary action, limited liability company or otherwise,  on the part of
Ruby, and its members and all necessary  consents of holders of  indebtedness of
Ruby have been obtained.

                  4.3 Binding Effect.  This Agreement and the Group  Transaction
Documents  executed  by any Seller or Member  constitute  the  legal,  valid and
binding  obligations  of  such  Seller  or  such  Member,  as the  case  may be,
enforceable  against it, him or her, as the case may be in accordance with their
respective terms.

                  4.4 Absence of Conflicting  Agreements.  Neither the execution
or delivery of this Agreement or any of the Group  Transaction  Documents by any
Group   Participant  nor  the  performance  by  any  Group  Participant  of  the
transactions  contemplated hereby and thereby,  conflicts with, or constitutes a
breach  of or a  default  under  or the  termination  of (a) in the case of each
Seller and Ruby, its Certificate of Organization or Operating Agreement;  or (b)
any judgment,  order, writ, injunction, or decree of any court applicable to any
Group  Participant;  or (c)  any  applicable  Federal,  state,  local  or  other
governmental  laws or ordinances,  or any applicable  order,  rule or regulation
("Governmental Requirements") of any Federal, state, local or other governmental
or quasi-governmental agency, bureau, board,  administrator,  court, commission,
department,  instrumentality,  body or other authority having  jurisdiction over
it, him or her ("Governmental  Authorities");  or (d) any agreement,  indenture,
contract or instrument to which any Group Participant is now a party or by which
any of them or any of the Assets is bound.

                                       19





                  4.5  Consents.  Except  as  set  forth  in  Schedule  4.5,  no
authorization,  consent, approval,  license, exemption by filing or registration
with any Governmental  Authority, is or will be necessary in connection with any
Group  Participant's  entry into,  execution,  delivery and  performance of this
Agreement or any of the Group Transaction Documents,  or for the consummation of
the transactions contemplated hereby and thereby.

                  4.6      Schedule of Assets and Properties.

                           (a)      Set  forth  in Schedule 4.6 are complete and
accurate lists of all of the material items  comprising the Assets and inventory
as of the date of this Agreement as follows:

                                    (i)   All machinery, vehicles and equipment,
office  equipment,  furniture and supplies  owned or leased by either Seller and
any other  items of personal  property  (not  otherwise  set forth on a schedule
hereto) that comprise or are otherwise used by either Seller in connection  with
any part of the Business.

                                    (ii) All patents, trademarks, service marks,
copyrights,  or applications for any of the same,  franchises,  rights and other
authorizations  (other than Licenses as set forth on Schedule  4.10 hereof),  if
any, and any other item of intangible or  intellectual  property that are owned,
possessed or used by either  Seller or any other person in the  operation of any
of the Business (the "Proprietary  Rights").  Schedule 4.6 sets forth any of the
foregoing items which have been registered  under any state or federal  statute.
All of the Proprietary  Rights of Seller are fully and freely  assignable by it,
and are free and clear of all Liens.

                  4.7      Contracts.

                           (a)     Schedules 4.7(b) and (c) set forth a complete
and correct list of all agreements,  leases,  contracts and commitments  whether
written or oral,  relating to the Business or to which either  Seller is a party
or by which any Seller or any of the Assets  are bound  (the  "Contracts").  The
Group has delivered to Buyer true,  complete and correct  copies of each written
Contract and a written  description  of each oral  Contract.  The Contracts were
entered into and require  performance in the ordinary course of business and are
in full force and effect.  No Seller is in default  under any Contract and there
has not been asserted,  either by or against any Seller under any Contract,  any
notice of default,  set-off or claim of default. Except as set forth on Schedule
4.7(b),  to the Knowledge of the Group,  the parties to the Contracts other than
Sellers are not in default of any of their respective  obligations  under any of
the  Contracts,  and there has not  occurred any event which with the passage of
time or the  giving of notice  (or both)  would  constitute  a default or breach
under any Contract.  Except as set forth in Schedule 4.7(b), all amounts payable
under each of the  Contracts  are, and will at the Closing Date, be on a current
basis.  Except as set forth in Schedule  4.7(b),  the  Contracts  are freely and
fully assignable to Buyer without the consent of the remaining  parties thereto.
No Group  Participant  has received  notice or has reason to believe that any of
the Contracts will be terminated by any party thereto  pursuant to any provision
thereof  permitting  any such party to terminate  such  Contract with or without
cause. If the Contracts with Concord  Extended Care and/or  Fairhaven of Chicago
Ridge
                                       20





are  re-negotiated  as  contemplated by the disclosure on Schedule  4.7(b),  the
revenues and profits  generated by such Contracts as so renegotiated  (including
the  addition of  Washington  Heights  Nursing  Center and  Tri-State  Nursing &
Rehabilitation Center) will not be materially reduced.

                           (b)    Except as listed in Schedule 4.7(b), no Seller
is a party to or liable in connection with and no Seller has granted any written
or express, oral or implied:

                                    (i)    contract, agreement or commitment for
the  employment  or  retention  of,  or  collective  bargaining,   severance  or

with any such person or persons;

                                    (ii)   agreement or arrangement for the sale
of any of its assets, property or rights outside the ordinary course of business
or requiring the consent of any party to the transfer and assignment of any such
assets,  property  or  rights  (by sale of  assets,  sale of  stock,  merger  or
otherwise);

                                    (iii)            contract which contains any
provisions  requiring  either Seller to indemnify or act for any other person or
entity or to guaranty or act as surety for any other person or entity;

                                    (iv)   agreement restricting any Seller from
conducting  business anywhere in the world for any period of time or restricting
its use or disclosure of any confidential or proprietary information;

                                    (v)     partnership,    joint   venture   or
management  contract or similar  arrangement or agreement which involves a right
to share  profits or future  payments  with  respect to the  business  of either
Seller or any portion thereof or the business of any other person or entity;

                                    (vi)     agreement    (including,    without
limitation,  management  agreements)  with any nursing home or hospital or other
facility or any professional  corporation with respect to the provision of Rehab
or O2 Services to patients or residents ("Provider Contracts");

                                    (vii)        licensing, distributor, dealer,
franchise,  sales or  manufacturer's  representative,  agency  or other  similar
contract, arrangement or commitment; or

                                    (viii)        agreement granting a leasehold
or other interest in real property (the "Leases");


                                       21





                                    (ix)      profit   sharing,  thrift,  bonus,
incentive,  deferred compensation,  stock option, stock purchase, severance pay,
pension, retirement hospitalization,  insurance or other similar plan, agreement
or  arrangement  applicable to any  employee,  consultant or agent to Seller not
covered by clause (i) above; or

                                    (x)     agreement  not  made in the ordinary
and normal  course of business and  consistent  with past  practice or involving
consideration in excess of $25,000 except as set forth in Schedule 4.17.

                           (c)      Schedule 4.7(c)  sets  forth  a complete and
correct list of all agreements,  contracts and  commitments,  whether written or
oral,  relating to the provision of Rehab Services or O2 Services as to which no
Seller  is a party,  but with  respect  to which  either  Seller  is acting as a
manager or  consultant  (the  "Related  Contracts").  The Group has delivered to
Buyer true,  complete and correct copies of each written Related  Contract and a
written  description of each oral Related  Contract.  The Related Contracts were
entered into and require  performance in the ordinary course of business and are
in full force and effect.  No provider is in default under any Related  Contract
and there has not been  asserted,  either by or against  any Seller or  provider
under any Related Contract, any notice of default,  set-off or claim of default.
Except as set forth on  Schedule  4.7(c),  to the  Knowledge  of the Group,  the
parties to the Related  Contracts other than the providers are not in default of
any of their  respective  obligations  under any of the Related  Contracts,  and
there has not occurred any event which with the passage of time or the giving of
notice  (or both)  would  constitute  a  default  or  breach  under any  Related
Contract. Except as set forth in Schedule 4.7(c), all amounts payable under each
of the Related Contracts are on a current basis. Except as set forth in Schedule
4.7(c), each Related Contract to which any Seller is a party is freely and fully
assignable  to Buyer without the consent of the remaining  parties  thereto.  No
Group  Participant  has received notice or has reason to believe that any of the
Related  Contracts  will be  terminated  by any party  thereto  pursuant  to any
provision  thereof  permitting any such party to terminate such Related Contract
with or without cause.

                  4.8      Financial Statements.

                           (a)      (i)    Attached hereto as Schedule 4.8(a)(i)
are the unaudited  consolidated  financial  statements of Sellers for the fiscal
quarters  ended  June 30,  1996 and March 31,  1996,  the  audited  consolidated
financial statements of Sellers for the fiscal year ended December 31, 1995, and
each Seller's unaudited  consolidated  financial  statements for the fiscal year
ended  December 31, 1994 and for each fiscal month since January 1, 1995 through
the date hereof,  in each case,  certified as true and correct by the applicable
Seller's chief  financial  officer (the "Financial  Statements").  The Financial
Statements  (including  any related  notes  thereto) are true and correct in all
material  respects and present  fairly the  financial  condition  and results of
operations of Sellers on a consolidated basis as, at and for the periods therein
specified  and were  prepared in  accordance  with GAAP except as expressly  set
forth on  Schedule  4.8.  The books of  account  of each  Seller  from which the
Financial Statements were prepared accurately reflect all of the items of income
and expense, assets, liabilities and accruals of Sellers on a consolidated

                                       22





basis. The income statements included in the Financial Statements do not contain
any items of special or  nonrecurring  income or expense or any other income not
earned or expense not  incurred  in the  ordinary  course of business  except as
expressly  specified  therein,   and  such  financial   statements  include  all
adjustments, which consist only of normal recurring accruals, necessary for such
fair presentation.

                                    (ii)  Attached hereto as Schedule 4.8(a)(ii)
are the unaudited  consolidated  financial  statements of Sellers for the fiscal
quarters  ended June 30,  1996 and March 31,  1996,  in each case,  adjusted  to
exclude therefrom the results of operations and the effect of the Excluded NY O2
Services, in each case, certified as true and correct by the applicable Seller's
chief  financial  officer (the "Adjusted  Financial  Statements").  The Adjusted
Financial Statements  (including any related notes thereto) are true and correct
in all material respects and present fairly the financial  condition and results
of operations of Sellers on a consolidated basis after adjustment to exclude the
results of  operations  and the effect of the Excluded NY O2 Services as, at and
for the periods  therein  specified and were  prepared in  accordance  with GAAP
except as expressly set forth on Schedule 4.8(a)(ii).

                           (b)      (i)      The  unaudited consolidated balance
sheet  contained in the Financial  Statements as of March 31, 1996 (the "Balance
Sheet")  reflects all liabilities as of the date thereof,  and no Seller has any
Liabilities that are not reflected thereon,  except for such current Liabilities
as have been incurred since the date of the Balance Sheet in the ordinary course
of business  consistent  with past practice and  Liabilities  listed on Schedule
4.8(b)(i).  There is no basis for the  assertion  against  either  Seller of any
Liability  of any  nature or in any amount  (other  than  current  or  scheduled
Liabilities as aforesaid) not fully reflected or reserved against in the Balance
Sheet.

                                    (ii)    The  unaudited  consolidated balance
sheet contained in the Adjusted  Financial  Statements as of March 31, 1996 (the
"Adjusted  Balance Sheet") reflects all liabilities as of the date thereof other
than liabilities  arising out of the Excluded NY O2 Services,  and no Seller has
any  Liabilities  that  are not  reflected  thereon,  except  for  such  current
Liabilities as have been incurred  since the date of the Adjusted  Balance Sheet
in the ordinary course of business consistent with past practice and Liabilities
listed on Schedule  4.8(b)(ii),  and other than  liabilities  arising out of the
Excluded NY O2 Services.

                  4.9 Material Changes.  Except as noted on Schedule 4.9 hereto,
between the date of the Balance Sheet and the date of this Agreement,  there has
not been any material adverse change in the condition  (financial or otherwise),
of the assets,  properties or operations of either  Seller,  and each Seller has
conducted its business only in the normal course, consistent with past practice.
The Group has identified and communicated to Buyer all material information with
respect to any fact or condition that, to the Group's Knowledge, might adversely
affect the future  prospects  (financial  or  otherwise)  of any of the Business
other than matters generally affecting the rehabilitation or respiratory service
industry.


                                       23





                  4.10 Licenses;  Permits;  Certificates of Need.  Schedule 4.10
sets forth a description of (a) each license and all other permits and approvals
of  Governmental  Authorities  relating  to the  operation  of any  part  of the
Business  heretofore  obtained  and that is now in  effect;  and (b) each  other
license,  permit,  easement,  right or other authorization that is necessary for
the operation of any part of the Business (collectively, the "Licenses"). Seller
has delivered to Buyer true,  correct and complete copies of all of the Licenses
and the  applications  therefor.  Schedule 4.10 also sets forth a description of
each  accreditation  of the Business,  copies of which Sellers have delivered to
Buyer.  Sellers own,  possess or have the legal right to use the Licenses,  free
and clear of all  Liens.  No  Seller  is in  default  under,  and no Seller  has
received  any notice of any claim or default  or any other  claim or  proceeding
relating to, any such License.  The Business is fully and completely licensed by
all  appropriate  Governmental  Authorities  to  carry  on  all  aspects  of the
Business. No member, director or officer,  employee or former employee of either
Seller,  or any  other  person,  firm or  entity  owns  or has any  proprietary,
financial or other interest, direct or indirect, in whole or in part in any such
License owned, possessed or used in the operation of any aspect of the Business.

                  4.11     Title, Condition to Personal Property.

                           (a)      Each Seller has good and marketable title to
all of the personal property comprising the Assets, subject to no liens, claims,
security interests,  mortgages,  pledges, charges,  easements, rights of setoff,
restraints  on  transfers,   restrictions  on  use,  options,  conditional  sale
agreements,  subleases,  sublicenses  and  encumbrances  of any  kind or  nature
whatsoever  ("Liens"),  other than Permitted  Liens. No person other than Seller
has any right to the use or  possession of any of such property and no currently
effective  financing  statement with respect to such personal  property has been
filed in any jurisdiction, and no Seller has signed any such financing statement
or any security  agreement  authorizing any secured party thereunder to file any
such financing  statement.  Since its  formation,  each Seller has conducted its
business  activities only under the limited liability company and/or trade names
set forth in  Section  1.1  hereto.  All of such  personal  property  comprising
equipment, improvements, furniture and other tangible personal property, whether
owned or leased,  is in good  operating  condition  and repair except for normal
wear and tear in the ordinary  course of  business,  and is  functioning  in the
manner and for the purpose for which it was intended and is in  compliance  with
(and the operation  thereof is in compliance  with) all applicable  Governmental
Requirements,  and is  sufficient  and  suitable to enable  Buyer to operate the
Business in a normal and efficient manner.

                           (b)      "Permitted Liens" means:

                                    (i)     each lien set forth on Schedule 4.11
(b) hereto;

                                    (ii)   carriers', warehouseman's, mechanics,
materialmen's, repairmen's or other like liens arising in the ordinary course of
business which are not overdue for a period of more than 30 days;


                                       24





                                    (iii)     deposits to secure the performance
of bids,  trade contracts  (other than for borrowed  money),  leases,  statutory
obligations, surety and appeal bonds, performance bonds and other obligations of
like nature incurred in the ordinary course of business, provided that each such
deposit shall be included in the Assets and shall not exceed  $15,000 in any one
case, or $75,000 in the aggregate;

                                    (iv)     pledges  or deposits  in connection
with worker's compensation,  unemployment  insurance,  and other social security
legislation; and

                                    (v)    the security interest granted to ANB;
provided that  provision  shall have been made for said security  interest to be
released and terminated at Closing as provided in Section 8.15 below.

                           (c)      Except  as set forth on Schedule 4.11(c), no
tangible  personal  property used by any Seller in connection with the operation
of the Business is subject to a lease, conditional sale, or similar arrangement.
Schedule  4.11(c)  sets forth a true,  complete  and correct copy of each of the
personal  property  leases  relating to the Business as to which any Seller is a
party (together with all modifications or amendments thereto), the annual rental
and unexpired  lease term thereby and all the  information  set forth thereon is
true, complete and correct.

                  4.12     Title, Condition of the Leased Properties.

                           (a)      No  Seller owns any real property or,  other
than the Leases,  has a leasehold or other  interest in any real  property.  The
applicable Seller has a valid leasehold  interest,  free and clear of all Liens,
in each of the properties covered by the Leases (the "Leased Properties").

                           (b)      There  are  no  leases, subleases  or  other
agreements  of any Seller as lessor or  sublessor,  granting any third party the
right to use or occupy  any of the  Leased  Properties  and no  person,  firm or
entity has any ownership interest (other than the landlord thereunder) or option
or right of first refusal to acquire any ownership interest in any of the Leased
Properties.

                           (c)      The  maintenance, operations and use by each
Seller of the  buildings  and other  improvements  comprising  any of the Leased
Properties  (the  "Improvements")  comply with and do not violate the applicable
lease or any zoning, building or similar law, ordinance,  order or regulation or
any statement of occupancy  issued for or in respect of the Business.  There has
been no violation of any  Governmental  Requirement  affecting any of the Leased
Properties  and no written  notice of any such  violation has been issued by any
Governmental  Authority.  To the Group's Knowledge,  the Improvements and all of
their systems,  including without limitation,  the heating,  ventilating and air
condition  systems,  and  the  plumbing,  electrical,  mechanical  and  drainage
systems,  and roofs are in good  operating  condition,  repair and working order
(except for

                                       25





normal  wear  and  tear  which  has not had a  material  adverse  effect  on the
condition  thereof),  and have  passed  all  previous  safety  and/or  licensing
inspections.

                  4.13 Legal  Proceedings.  Other than as set forth on  Schedule
4.13, there are no disputes, claims, actions, suits or proceedings, arbitrations
or  investigations,  either  administrative  or  judicial,  pending,  or, to the
Group's Knowledge, threatened or contemplated, nor, to the Group's Knowledge, is
there any basis  therefor,  against or affecting  Seller or any of the Assets or
Seller's  rights  therein or the ability of any Group  Participant to consummate
the transactions  contemplated herein, at law or in equity or otherwise,  before
or by any court or governmental  agency or body,  domestic or foreign, or before
an arbitrator of any kind, including,  without limitation,  any of the foregoing
relating to the infringement of proprietary  rights. No Participant of the Group
has  received  any requests  for  information  with respect to the  transactions
contemplated hereby from any Governmental Authority.

                  4.14 Employees.  Schedule 4.7(b)(i) and Schedule 4.14 together
contain a true, complete and correct list of the name, position, current rate of
compensation  and any vacation or holiday pay, sick pay,  personal leave and any
other  compensation  arrangements or fringe benefits,  of each current employee,
consultant  and agent of Seller  (together  with a  description  of any specific
arrangements  or rights  concerning  such persons that are not  reflected in any
agreement or document referred to in Schedule 4.7). Each Seller is in compliance
with all  Governmental  Requirements  applicable to any of the employee  benefit
plans, agreements and arrangements identified on Schedule 4.7(b)(ix), including,
without  limitation,  the Employee  Retirement  Income  Security Act of 1974, as
amended  ("ERISA").  No such  employee,  consultant or commission  agent has any
vested or unvested retirement benefits or other termination benefits,  except as
described on Schedule  4.7(b)(i) or (ix). The Balance Sheet contains an adequate
reserve for  vacation,  sick  leave,  severance  and all other  employee-related
accruals.

                  4.15  Collective  Bargaining,   Labor  Contracts,   Employment
Practices,  etc.  During the two (2) years prior to the Closing Date,  there has
been no material  adverse change in the  relationship  between either Seller and
any two or more employees acting together nor any strike or labor disturbance by
any of such  employees  affecting the Business and there is no  indication  that
such a change,  strike or labor  disturbance  is likely.  No employees of either
Seller are represented by any labor union or similar  organization in connection
with their  employment by or relationship  with, any Seller,  and to the Group's
Knowledge there are no pending or threatened  activities the purpose of which is
to achieve such  representation of all or some of such employees.  Except as set
forth on  Schedule  4.15,  there are no pending  suits,  actions or  proceedings
against any Seller relating to any of its past or present respective  employees,
and there are no threats of strikes, work stoppages or pending grievances by any
such  employees.  Except  as set  forth on  Schedule  4.15,  no  Seller  has any
collective bargaining or other labor contracts.

                  4.16     ERISA.  No Seller maintains or makes contributions to
and no Seller has at any time in the past  maintained or made  contributions  to
any employee benefit plan which is

                                       26





subject to the minimum funding  standards of ERISA. No Seller maintains or makes
contributions to or has at any time in the past maintained or made contributions
to any multi-employer  plan subject to the terms of the  Multi-employer  Pension
Plan Amendment Act of 1980 (the "Multi- employer Act").

                  4.17 Insurance and Surety Agreements. Schedule 4.17 contains a
true and correct list of: (a) all policies of fire, liability and other forms of
insurance  held or owned by any  Seller  or  otherwise  in force  and  providing
coverage for the Business or any of the Leased  Properties or Assets  (including
but not limited to medical malpractice  insurance,  and any state sponsored plan
or program for worker's  compensation);  (b) all bonds, indemnity agreements and
other  agreements of  suretyship  made for or held by any Seller or otherwise in
force and  relating to the Business or any of the Leased  Properties  or Assets,
including a brief  description  of the character of the bond or  agreement,  the
name of the surety or the indemnifying party.  Schedule 4.17 sets forth for each
such insurance policy the name of the insurer, the amount of coverage,  the type
of insurance,  the policy number,  the annual premium and a brief description of
the nature of insurance  included  under each such policy and of any claims made
thereunder  during the past two years.  Such  policies  are owned by and payable
solely to Sellers, and said policies or renewals or replacements thereof will be
outstanding and duly in force at the Closing Date. All insurance policies listed
on Schedule 4.17 are in full force and effect, all premiums due on or before the
Closing Date have been or will be paid on or before the Closing  Date, no Seller
has been advised by any of its  insurance  carriers of an intention to terminate
or  modify  any such  policies,  nor has it  failed  to  comply  with any of the
material conditions contained in any such policies.

                  4.18  Relationships.  Except as disclosed on Schedule 4.18, no
officer,  director  or employee of either  Seller,  no Member,  no member of any
Member's immediate family, and no person or entity which is controlled by, under
common control with or controlling any of them (each,  an "Affiliate")  has, and
at no time within the last two (2) years has had, a material  ownership interest
in any business,  corporate or otherwise, that is a party to, or in any property
that is the subject  of,  business  relationships  or  arrangements  of any kind
relating to the operation of the Business.

                  4.19 Assets  Comprising  the Business.  The Assets,  including
without limitation,  the inventory included therein,  and the Leased Properties,
Contracts,  Proprietary  Rights and  Licenses  listed on the  Schedules  to this
Agreement as owned by Sellers represent all of the property (real,  personal and
mixed), licenses, intellectual property, permits and authorizations,  contracts,
leases and other  agreements  that are necessary or material to the operation of
the Business as now operated (the "Necessary  Assets"),  except for the Excluded
Assets.  No Medicare or Medicaid provider number is necessary or appropriate for
the operation of the Business  because  Sellers do not directly bill Medicare or
Medicaid.

                  4.20     Absence of Certain Events.     Except as set forth on
Schedule 4.20, since the date of the Balance Sheet, no Seller has:

otherwise), properties, assets, liabilities,  operations, business or prospects;
or

                           (l)      entered into any  material transaction other
than in the ordinary course of business consistent with past practice.

                  4.21     Compliance with Laws.

                           (a)      Each Seller  is in compliance with all laws,
statutes,  rules,  regulations,  orders,  and  ordinances,  and to  the  Group's
Knowledge,  with all directives and guidelines,  of all Governmental Authorities
applicable to any or all of it, its Assets and the operation of the Business. No
Seller has  received  any claim or notice that any of the Leased  Properties  or
Assets is not in compliance with any applicable Governmental  Requirements.  The
Group shall report to Buyer, within five (5) days after its receipt thereof, any
written or oral claims or notices  that any of the Leased  Properties  or Assets

hazardous,  toxic or  infectious  waste,  material or  substance  or  (including
Medical Waste) and petroleum  products,  material or waste whether  performed on
any of the  Leased  Properties  or at any other  location.  No  notice  from any
Governmental  Authority has ever been served upon either  Seller,  or any of its
agents or  representatives  claiming any violation of any Environmental  Law, or
requiring or calling attention to the need for any work, repairs, or demolition,
on or in  connection  with any of such  properties  in order to comply  with any

                  5.2  Power  and  Authority.  Each  of IHS  and  Buyer  has the

agreements  required  to be  delivered  by it  to  the  Group  at  the  Closing,
including, without limitation, the Escrow Agreement (collectively the "Buyer/IHS
Transaction  Documents")  and all of the  transactions  contemplated  hereby and
thereby.

                  5.3 Binding  Agreement.  This Agreement has been duly executed
and delivered by each of IHS and Buyer. This Agreement is, and when executed and
delivered  by Buyer or IHS,  as the case  may be,  at the  Closing,  each of the
Buyer/IHS  Transaction  Documents  executed by Buyer or IHS, as the case may be,
will be, the legal,  valid and binding  obligation  of Buyer or IHS, as the case
may be, enforceable against Buyer or IHS, as the case may be, in accordance with
their respective terms.

                  5.4 Absence of Conflicting  Agreements.  Neither the execution
or delivery of this Agreement or any of the Buyer/IHS  Transaction  Documents by
Buyer or IHS,  as the case may be, nor the  performance  by Buyer or IHS, as the

with,  or  constitutes  a breach  of or a  default  under  (a) the  Articles  of
Incorporation  or  By-Laws  of  Buyer or IHS,  as the  case  may be;  or (b) any
applicable judgment, order, writ, injunction, or decree of any court; or (c) any
applicable Governmental Requirement; or (d) any agreement,  indenture,  contract
or  instrument  to which  Buyer or IHS, as the case may be, is now a party or by

annual  meeting  held  on May  23,  1996  (the  "SEC  Documents").  As of  their
respective dates, none of the SEC Documents contained any untrue statements,  or

render  any of such  documents  materially  misleading,  and  the SEC  Documents
complied  when  filed  in  all  material   respects  with  the  then  applicable
requirements of the Exchange Act, and the rules and  regulations  promulgated by
the Commission thereunder.

each  Seller's  financial  and  legal  condition  as Buyer  deems  necessary  or

into in the ordinary  and  customary  course of business  with  unrelated  third
parties on customary terms and conditions and for customary  prices as disclosed

or other  entity  which is directly  or  indirectly  in the  business of owning,

business, licensed or unlicensed, now or hereafter competitive with any contract
rehabilitation  or respiratory  service  business of Buyer  (including,  without
limitation, the Business), IHS or any of their respective Affiliates, located in
any or all of the States of Illinois, or Missouri or within twenty (20) miles of
Deland,  Florida or thirty (30) miles of New York City, New York or Kansas City,
Kansas (the  "Prohibited  Areas"),  or which business  solicits from or performs
contract  rehabilitation  or respiratory  services for any current  customers or
clients of the Business or any owner,  lessee or manager of any such customer or
client ( "Protected  Customers").  Each Ruby Member represents and warrants (and
notwithstanding  anything to the contrary  contained in this Agreement,  none of
Dacy,  Krause  and  neither  Seller  shall be  deemed  to have  represented  and
warranted)  that  the  only  persons  owning,  leasing,   managing,   performing

such  Ruby  Member  has a  relationship  that  would  give  such  Ruby  Member a

Source"). Schedule 8.10 also identifies the relationship of the Protected Source

limitation,  under Section 10.3 of this Asset Purchase  Agreement;  (y) does not
directly or indirectly  participate in the provision or solicitation of contract
rehabilitation  or respiratory  services business in any of the Prohibited Areas
or to or  with  any  of the  Protected  Sources;  provided,  however,  that  the
foregoing shall not be deemed to prohibit him or her from  participating  in any
general mass  marketing  effort which covers an area of which one or more of the
Prohibited  Areas  constitutes an incidental and  insubstantial  part, such as a
national  campaign,  and that does not involve personal contact by him or her in
any Prohibited Areas or personal contact with any Protected Source or use of any
confidential  information  referred  to in Section  10.3 of this Asset  Purchase
Agreement;  and (z) delivers to Buyer and IHS his or her written  acknowledgment
setting  forth:  the  name and  address  of the  business  in which he or she is
participating;  that he or she has  delivered to such  business a copy of his or
her Non-Competition  Agreement;  and that he or she continues to be bound by the
provisions of the Non-Competition  Agreement.  No Ruby Member shall be deemed to
be in violation of this Section 8.10 by reason of the acquisition and subsequent
ownership  by any  Protected  Customer of any business to which such Ruby Member
shall be providing contract rehabilitation or respiratory services prior to such
acquisition.  Said  Non-Competition  Agreements  also shall  contain  provisions
relating to non-solicitation of Protected Sources,  and of employees,  agents or
consultants of Buyer and

                                       37





Sellers. The Non-Competition Agreements shall not prohibit the ownership of less
than 0.1% of the issued and outstanding stock of any competitive  business whose
stock is listed  on a  national  securities  exchange  or  traded on the  NASDAQ
national market system.  Buyer and IHS agree that the Non-Competition  Agreement
shall not prohibit any Group Participant: (a) from continuing to own an interest
in and participating in the oxygen concentration  business as currently operated
by C.O.M.S.;  provided  that the Group  represents  and  warrants  that the only
connection  that  C.O.M.S.  has to O2 or Rehab  Services is supplying or leasing
durable medical equipment,  including, without limitation,  oxygen concentration
equipment;  or (b)  unless  otherwise  agreed  in such  person's  employment  or
consulting  agreement with Buyer, from operating a respiratory services business
in the State of New York;  provided,  however,  that no Group  Participant shall
provide  any such  services  (or solicit to provide  any such  services)  to the
Southshore Home.

                  8.11  Employment and Consulting  Agreements.  Buyer shall have

Consolidated Omnibus Budget  Reconciliation Act of 1985 ("COBRA"),  and which is
required to be given,  made,  paid,  obtained,  and performed as a result of the
Closing under this Agreement. This provision shall not be construed, however, to
require  Seller  to  maintain  its group  health  insurance  coverage  following
Closing, except as may be required by applicable Governmental Requirements.  IHS
shall take such steps as are commercially  reasonable to permit former employees
of Sellers to obtain  COBRA  coverage  under  insurance  plans  available to IHS
employees.

                  8.13 Assets  Transferred  at Closing.  Each Seller  shall have
delivered or caused to be delivered  to Buyer  possession  of the Assets (or the
right to obtain  possession  on  demand).  Each  Seller  shall also  execute and
deliver to Buyer at Closing such UCC financing  statements as shall be necessary
or  appropriate  to record  the  assignment  to Buyer of all  recorded  security
interests  held by  either  Seller.  All  Assets  shall be free and clear of all
Liens.

Section 1.5(b) hereof by reason thereof.

                  8.15 ANB  Security  Interest.  ANB  shall  have  executed  and
delivered to Buyer a payout letter setting forth the total amount of obligations
due to it as of the Closing Date and agreeing that, upon payment thereof on such
date,  its  security  interest in all of the Assets and all  guarantees  of said
obligations  (the  "Guarantees")  shall be released and terminated.  Such payout
letter  shall be in form  and  substance  satisfactory  to  Buyer  and  shall be
accompanied by all UCC

                                       38





termination  statements (to be held pending the occurrence of the conditions set
forth in said letter)  necessary to evidence said release and  termination.  All
costs incurred in connection  with  satisfying  this condition shall be borne by
Sellers.

                  8.16     Lease Amendment.  The Lease Agreement between Sellers
and 3100  Commercial  Partners  shall  have been  amended to  terminate  with no

                  10.2     Indemnification.

                           (a)      Each  Seller and each Member jointly (except

IHS and each of their respective shareholders,  directors,  officers, employees,
agents and advisors, and each of their respective successors and assigns ("Buyer
Indemnitees") against and with respect to any and all damages,  losses,  claims,
liabilities,  deficiencies,  costs and expenses (including,  without limitation,
reasonable  attorney's  fees and  expenses)  (all of the  foregoing  hereinafter

foregoing.  Notwithstanding the foregoing, no Member shall be jointly liable for
any breach of a  representation  or warranty  by any other  Member to the extent
such  representation  or warranty  was  expressly  made  severally by such other
Member in accordance with this Agreement.

                  Without  limiting the foregoing,  the Group hereby  represents
and  warrants  to  Buyer  and IHS  that it has  complied  with  any and all bulk

expenses incident to any of the foregoing.

                           (c)      Any claim for indemnification for any breach
of a representation  or warranty under this Section 10.2 or for a Loss described
in Section  10.2(a)(v)  above must be  asserted  by written  notice by the first

warranties of any of the Group  Participants  for any tax matter may be asserted
any time prior to expiration of the applicable  statute of  limitations  for the
assertion of the related tax claim by the  government,  and any such claim based
on Excess Reimbursement  Liability may be brought any time prior to a date which

by reason of any Group Participant's obligations under this Section 10.2 hereof.
To the extent any Buyer  Indemnitee shall be entitled to  indemnification  under
this Section 10.2, such Buyer Indemnitee shall first seek to recover against the
Escrow Deposit prior to proceeding against the assets of any Group Participants.

                           (e)      The  aggregate amount  for  which the  Group
Participants shall be liable for indemnification  obligations under this Section
10.2 shall not exceed the amount of the Purchase Price, as adjusted  pursuant to
Sections 1.6 and 2.3 hereof.

                  10.3     Restrictions.

                           (a)      From  and  after the  Closing Date, no Group
Participant shall disclose,  directly or indirectly, to any person or entity, or
make use of, without the express  authorization of IHS and Buyer, any non-public
pricing  strategies or records of either Seller,  any proprietary  data or trade
secrets  owned  by  either  Seller,  Buyer  or  IHS or any  financial  or  other
information about any of them  ("confidential  information");  provided that the
foregoing restrictions shall not apply to any information which:

                                    (i)     is or becomes publicly known through
no wrongful act on the part of any Seller or Member; or

                                    (ii)    is  or  becomes  available  to   the
disclosing  party  on  a  non-confidential  basis  from a  third  party  without
restriction and without breach of this Agreement; or

                                    (iii)    is approved for release by  written
authorization signed by Buyer; or

                                    (iv)     is   required  to   be disclosed in
accordance  with  applicable law;  provided,  however,  prior to making any such
disclosure the party required to make such  disclosure  shall provide Buyer with
prompt  notice  of such  requirement  to  enable  Buyer  to seek an  appropriate
protective order and such party will use its best efforts to preserve the

                                       42





confidentiality  of such  information and will disclose only that portion of the
information as is required to be disclosed.

                           (b)      Each Group Participant acknowledges that the
restrictions  contained  in this Section 10.3 are  reasonable  and  necessary to
protect  the  legitimate  business  interests  of Buyer  and  IHS,  and that any
violation  thereof by any of them would result in irreparable  harm to Buyer and
IHS.  Accordingly,  each Group Participant agrees that upon the violation by any
of them of any of the restrictions contained in this Section 10.3, Buyer and IHS
shall  be  entitled  to  obtain  from  any  court of  competent  jurisdiction  a
preliminary and permanent injunction as well as any other relief provided at law
or equity,  under this Agreement or otherwise,  without the necessity of posting
any bond or security whatsoever.

                  10.4 Records.  On the Closing Date,  each Seller shall use its
best  efforts to  deliver,  or cause to be  delivered,  to Buyer all records and
files not then in such  Seller's  possession  relating to the  operation  of the
Business.  Following the Closing,  Buyer shall provide either Seller with access
during  business  hours  upon  reasonable  prior  notice  (not less than two (2)
business  days), to such of its financial  records  relating to the operation of
the  Business  prior to the Closing  Date as Buyer shall  reasonably  request in
connection  with the  preparation  by it of any tax returns or the collection of
any accounts receivable owned by it.

                  10.5  Appeal of Denials and  Disallowances.  If there shall be
any claim for Excess Reimbursement Liability,  Buyer will contest or appeal such
claim (using at least the same standard of care as it would apply to contests or
appeals with respect to its own  reimbursement  liabilities)  in accordance with
the  procedures  set forth in  Buyer's  manual.  After any  contest or appeal in
accordance with the foregoing, Sellers shall within ten (10) business days after
any request by Buyer, accompanied by a log of procedures performed in accordance
with Buyer's  manual with respect to such claim and copies of all  documentation
submitted  to third  payors in  connection  therewith,  pay and satisfy any such
claim that was denied.  If Sellers  shall fail to comply with the  provisions of
this  Section  10.5,  then Buyer shall have the right,  but shall in no event be
obligated, to make any such payment on behalf of Sellers, in which case, Sellers
shall,  upon demand,  immediately  reimburse Buyer for any amount so paid by it.
The rights of Buyer under this Section 10.5 are in addition to, and shall not be
deemed to limit,  any other rights or remedies which Buyer might have under this
Agreement,  law,  equity or  otherwise.  Neither  Buyer  nor IHS shall  have any
obligation  with respect to any appeals or contests  arising out of any Excluded
NY O2 Service.  Buyer's obligations under this Section 10.5 shall be conditioned
on the cooperation of the Group  Participants,  including,  without  limitation,
their providing Buyer with all appropriate documentation to support an appeal or
contest in their possession or under their control.  Buyer shall not be required
to incur any extraordinary expense except to the extent required pursuant to the
manual in connection with its obligations under this Section 10.5 unless Sellers
shall have agreed to advance the funds therefor.

                  10.6     Audit.  Following Closing, each Seller will cooperate
with and assist Buyer in a review of the  financial  statements  of such Seller.
Buyer may, at its own expense, have an

                                       43





audit  performed of such  financial  statement,  and each Seller and Member will
cooperate in the performance of such audit.

                  10.7 Offer of Employment.  Except for Philip Esformes,  Andrew
Fleming and Lynn Mershon and employees working principally in the Excluded NY 02
Services,  Buyer  agrees to offer to retain (for so long as it deems it to be in
its best interests), after the Closing, the services of substantially all of the
licensed  professionals  and office staff who are  employees of either Seller on
the date hereof and on the Closing Date.

                  10.8 Option on Excluded NY 02 Services.  At any time after the
Closing  and on or prior  to the day  that is 30 days  after  the  Closing  (the
"Option  Period"),  Buyer  shall be  entitled  to acquire all of the assets then
relating  to the  Excluded  NY O2 Services  (the "O2  Business")  for no further
consideration  other than the assumption of all of the liabilities then relating
to the Excluded NY O2 Services as such liabilities are represented by Sellers to
Buyer at the time of such  acquisition.  Such option shall be exercisable by the
giving of notice to Sellers  during such  Option  Period and the closing of such
acquisition  shall  occur on such date as Buyer shall  designate  in such notice
(the  "Option  Closing");  provided  that such date shall be a business  day and
shall not be more than thirty (30) days or less than (10) days after the date of
such notice.  The Option Closing shall take place by mail and escrow in a manner
reasonably  satisfactory to each of the parties thereto.  At the Option Closing,
Sellers  shall  execute and  deliver to Buyer such bills of sale and  assignment
instruments as Buyer shall reasonably require to effectuate the acquisition, and
Sellers shall make such customary representations and warranties with respect to
the O2 Business, the subject assets and liabilities, the authority of Sellers to
complete the contemplated  transaction and such other customary  representations
and warranties as Buyer shall reasonably require.  At the Option Closing,  Buyer
shall  execute and deliver to Sellers  such  assumption  instruments  as Sellers
shall reasonably require to effectuate the assumption of liabilities,  and Buyer
shall make such customary  representations  and  warranties  with respect to the
acquisition and its authority as Sellers shall reasonably require. Sellers shall
use their  reasonable  efforts to advise Buyer of any material  occurrences with
respect to the O2 Business and shall promptly provide Buyer with any information
reasonably  requested  by it with  respect to the O2 Business  during the Option
Period. Notwithstanding anything to the contrary contained in this Section 10.8,
Sellers  shall be entitled to liquidate  and wind-up the O2 Business at any time
during  the  Option  Period;  provided  that  Sellers  shall give Buyer at least
fifteen (15) days prior written notice before it shall commence such process and
before  it shall  terminate  any  contracts  pursuant  to which it  directly  or
indirectly  provides O2 Services.  Except as provided  above,  Sellers shall not
sell or encumber any of the assets of the O2 Business  during the Option Period,
except in the ordinary course of business  consistent with past practice.  Buyer
shall pay to Sellers  upon  completion  of the  acquisition,  if any,  of the 02
Business  pursuant to this Section 10.8 the amount, if any, by which the sum of:
(x) current assets included in such acquisition  plus (y) $150,000,  exceeds the
current liabilities assumed by Buyer pursuant thereto, in each case,  determined
in accordance with GAAP; provided,  however,  that such payment shall not exceed
the amount,  if any, by which the Purchase Price is reduced  pursuant to Section
2.3 hereof. During the Option Period and for thirty (30) days thereafter Sellers
shall  make  available  to Buyer  the  services  of Tim  Fisher  (if he is still
employed by Sellers; provided, however, that the

                                       44





provision by Tim Fisher shall not interfere with his obligations to Seller), and
Buyer shall make  available to Sellers the services of R. Paler,  Andrew Fleming
and a billing  person  if they are  employed  or  retained  by  Buyer;  provided
however,  that the provision by R. Paler, Andrew Fleming and such billing person
shall not interfere  with any such  person's  obligations  to Buyer.  During the
Option Period and for thirty (30) days thereafter  Sellers,  shall not terminate
the  employment  of Tim  Fisher  without  having  given  Buyer at least five (5)
business days prior notice.  Thirty (30) days  following the  termination of the
Option  Period,  Sellers  shall  provide  Buyer  with the  opportunity  to offer
employment or  consulting  arrangements  to Tim Fisher,  and Sellers shall fully
cooperate  with Buyer to encourage  Tim Fisher to accept any such  employment or
consulting  arrangements.  Neither Buyer nor Sellers shall be reimbursed for the
cost of providing  the other with the  services of its  employees as required by
this Section 10.8; provided, however, that the costs of transportation, room and
board of such  employees in connection  with  providing the services  under this
Section 10.8 shall be borne by the party for whom the services are provided.


                             ARTICLE XI: TERMINATION
                             -----------------------

                  11.1     Termination.  This Agreement may be terminated at any
time at or prior to the time of Closing by:

                           (a)      Buyer,  if  any  condition  precedent to the
obligations  of Buyer  or IHS  hereunder,  including  without  limitation  those
conditions  set forth in Article  VIII  hereof,  have not been  satisfied by the
Closing Date or pursuant to Section 12.1 if any portion of the Assets is damaged
or destroyed as a result of fire, other casualty or from any reason whatsoever;

                           (b)      Sellers,  if  any condition precedent to the
obligations  of  the  Group  hereunder,   including  without   limitation  those
conditions  set forth in  Article  IX  hereof,  have not been  satisfied  by the
Closing Date;

                           (c)      the mutual consent of Buyer and Sellers.

                  11.2  Effect  of  Termination.  If  a  party  terminates  this
Agreement because one of its conditions precedent has not been fulfilled,  or if
this Agreement is terminated by mutual consent, this Agreement shall become null
and void  without any  liability of any party to the other;  provided,  however,
that if such  termination  is by reason of the breach by any party of any of its
representations, warranties or obligations under this Agreement, the other party
shall be  entitled  to be  indemnified  for any Losses  incurred by it by reason
thereof in  accordance  with  Section  10.2 hereof (and for such  purposes  such
Section 10.2 shall  survive the  termination  of this  Agreement).  Furthermore,
nothing  in this  Section  11.2  shall  affect  any  party's  right to  specific
performance of the obligations of the Group at Closing hereunder.

                       ARTICLE XII: CASUALTY, RISK OF LOSS
                       -----------------------------------


                                       45





                  12.1  Casualty,  Risk of Loss.  Sellers shall bear the risk of
all loss or damage to any of the Assets from all causes which occur prior to the
Closing.  If at any time  prior to the  Closing  any  portion  of the  Assets is
damaged  or  destroyed  as a result of fire,  other  casualty  or for any reason
whatsoever,  Sellers shall immediately give notice thereof to Buyer. Buyer shall
have the right,  in its sole and  absolute  discretion,  within ten (10) days of
receipt  of such  notice,  to (1)  elect not to  proceed  with the  Closing  and
terminate  this  Agreement,  or  (2)  proceed  to  Closing  and  consummate  the
transactions  contemplated  hereby and  receive any and all  insurance  proceeds
received or  receivable  by any Group  Members on account of any such  casualty.
Nothing contained in this Section 12.1 shall limit or adversely affect the right
of Buyer and IHS to receive indemnification for any Losses incurred by either of
them by reason of any  breach by any Group  Participant  of any  representation,
warranty or  obligation  under this  Agreement in  accordance  with Section 10.2
hereof (and for such purposes such Section 10.2 shall survive the termination of
this Agreement).


                           ARTICLE XIII: MISCELLANEOUS
                           ---------------------------

                  13.1  Costs  and  Expenses.   Except  as  expressly  otherwise
provided  in this  Agreement,  each  party  hereto  shall bear its own costs and
expenses in connection  with this  Agreement and the  transactions  contemplated
hereby. The Group shall pay all sales, transfer, recording, stamp and like taxes
payable  in  connection  with  any  of the  transactions  contemplated  by  this
Agreement,  and shall  timely and  truthfully  complete  and file any filings or
returns necessary in connection therewith. The Group, on the one hand, and Buyer
and IHS on the other hand,  shall each bear fifty  percent  (50%) of the cost of
obtaining the legal opinions  referred to in Section  8.4(b) hereto.  Subject to
Section 2.4 hereof, Buyer and IHS agree that Sellers may use shares of IHS Stock
to pay  the fee due to its  consultant,  C-III,  L.L.C.  (the  "Consultant"),  a
Missouri  limited  liability  company,  provided that said Consultant shall have
agreed in writing, in form and substance satisfactory to IHS, to be bound by the
provisions of Section 2.5 hereof (including 2.5(b) and (e)).

                  13.2 Benefit and  Assignment.  This Agreement binds and inures
to the benefit of each party hereto and its  successors  and  assigns.  Prior to
Closing,  Buyer may not assign its  interest  under this  Agreement to any other
person or entity  without  the  prior  written  consent  of  Sellers;  provided,
however,  that  prior to  Closing  Buyer  may  assign  its  rights,  duties  and
obligations  hereunder to one or more  subsidiaries or affiliates of IHS, except
that  no  such  assignment  shall  operate  to  relieve  IHS of its  obligations
hereunder.

                  13.3 Effect and Construction of this Agreement. This Agreement
and the Exhibits,  Schedules  and the  Transaction  Documents  embody the entire
agreement  and  understanding  of the  parties and  supersede  any and all prior
agreements,  arrangements  and  understandings  relating to matters provided for

                                       46





construction of the provisions of this Agreement. This Agreement may be executed
in one or more counterparts,  and all such counterparts shall constitute one and
the same instrument.

                  13.4 Cooperation - Further  Assistance.  From time to time, as
and when reasonably  requested by any party hereto after the Closing,  the other
parties will (at the expense of the requesting  party)  execute and deliver,  or
cause to be executed and delivered, all such documents, instruments and consents
and will use  reasonable  efforts to take all such  action as may be  reasonably
requested or  necessary to carry out the intent and purposes of this  Agreement,
and to vest in Buyer  good  title to,  possession  of and  control of all of the
Assets.

Section 13.5.

                  13.6  Waiver,   Discharge,   Etc.   This   Agreement  and  the
Transaction  Documents and the obligations hereunder and thereunder shall not be
released,  discharged,  abandoned,  changed,  waived or  modified in any manner,
except by an instrument in writing executed by Sellers, if any Group Participant
is to be the party to be  charged,  and by  Buyer,  if Buyer or IHS is to be the
party to be charged.  The failure of any party to enforce at any time any of the
provisions of this Agreement  shall in no way be construed to be a waiver of any
such  provision,  nor in any way to affect the validity of this Agreement or any
part hereof or the right of any party  thereafter to enforce each and every such
provision.  No waiver  of any  breach  of this  Agreement  shall be held to be a
waiver of any other or subsequent breach.

                  13.7 Rights of Persons Not Parties.  Nothing contained in this
Agreement shall be deemed to create rights in persons not parties hereto,  other
than the successors and proper assigns of the parties hereto, and other than the
Buyer Indemnitees and Group Indemnitees pursuant to Section 10.2 hereto.

                  13.8 Governing  Law. This  Agreement  shall be governed by and
construed  in  accordance  with  the  internal  laws of the  State  of  Illinois
applicable to contracts  executed,  delivered and to be fully  performed in such
State,  disregarding  any contrary  rules  relating to the choice or conflict of
laws.

                  13.9 Amendments, Supplements, Etc. At any time before or after
the  execution  and  delivery  of this  Agreement  by the parties  hereto,  this
Agreement may be amended or supplemented by additional  agreements,  articles or
certificates,  as may be mutually  determined  by the  parties to be  necessary,
appropriate or desirable to further the purposes of this  Agreement,  to clarify
the intention of the parties, or to add to or to modify the covenants,  terms or
conditions  hereof or thereof.  The  parties  hereto  shall make such  technical
changes to this Agreement,  not inconsistent with the purposes hereof, as may be
required to effect or facilitate any governmental approval or acceptance of this
Agreement or to effect or  facilitate  any filing or recording  required for the
consummation  of any  portion  of the  transactions  contemplated  hereby.  This
Agreement  may not be  amended  except by an  instrument  in  writing  signed by
Sellers on behalf of the Group Members and by Buyer on behalf of Buyer and IHS.

                  13.10 Severability.  Any provision, or distinguishable portion
of any  provision,  of this  Agreement  which is  determined  in any judicial or
administrative  proceeding to be prohibited or unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such prohibition
or unenforceability  without  invalidating the remaining  provisions hereof, and
any  such  prohibition  or   unenforceability  in  any  jurisdiction  shall  not
invalidate or render unenforceable such provision in any other jurisdiction.  It
is the  intention of the parties that if any  provision of Section 10.3 shall be
determined to be overly broad in any respect, then it

                                       48





should be enforceable to the maximum  extent  permissible  under the law. To the
extent permitted by applicable law, the parties waive any provision of law which
renders a provision hereof prohibited or unenforceable in any respect.

                  13.11 Public  Announcements.  Any general public announcements
or similar media  publicity with respect to this  Agreement or the  transactions
contemplated  herein  shall be at such  time  and in such  manner  as IHS  shall
determine; provided that nothing herein shall prevent either party, upon as much
prior notice as shall be possible  under the  circumstances  to the other,  from
making such written announcements as such party's counsel may consider advisable
in order to  satisfy  the  party's  legal and  contractual  obligations  in such
regard.

                  13.12 Joint and Several.  Except as expressly set forth in the
rules of construction  and  qualification  in the preamble to Article IV of this
Agreement,   all  obligations,   representations,   warranties,   covenants  and
agreements  of any Group  Participant  under this  Agreement or any of the Group
Transaction   Documents   shall   be  the   joint   and   several   obligations,
representations,  warranties,  covenants  and  agreements  of all  of the  Group
Members.
