ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

On November 27, 1996, Home Health Corporation of America, Inc. (the "Company")
acquired from Randy DiSalvo all of the outstanding capital stock of R.S.D.
Management Services, Inc., a provider of primarily Medicare-reimbursed nursing
and related patient services with approximately $18.3 million of net revenues
for the twelve month period ended June 30, 1996 and operations in Massachusetts
and New Hampshire (the "RSD Acquisition"). The consideration paid for the RSD
Acquisition was approximately $11.4 million, consisting of $9.4 million in cash,
which includes repayment of $4.3 million in indebtedness, $1.0 million in notes,
and the balance by the issuance of 91,118 shares of the Company's common stock.
The cash portion of this consideration was paid through borrowings under the
Company's senior credit facility. This acquisition will be accounted for as a
purchase.

ITEM 5.  OTHER EVENTS

On December 5, 1996, the Company signed a definitive agreement to acquire
certain assets and assume certain liabilities of LHS Holdings, Inc. and certain
of its subsidiaries and affiliates, providers of primarily Medicare-reimbursed
nursing and related patient services and, to a lesser extent, infusion therapy
services, with $16.0 million in net revenues for the twelve month period ended
June 30, 1996 and operations in Texas (the "LHS Acquisition"). The aggregate
consideration payable for the LHS Acquisition is approximately $9.3 million,
including a contingent amount estimated at $2.7 million based upon four and one-
half times the earnings before interest, taxes, depreciation and amortization of
certain of the companies being acquired in this acquisition. The aggregate
consideration payable for the LHS Acquisition, excluding the contingent amount,
is comprised of approximately $5.1 million in cash, $1.0 million in notes, and
the balance in shares of the Company's common stock. This acquisition will be
accounted for as a purchase.

  Calendar Year             Target Net Revenue
  -------------             ------------------

     "Eligible Companies" shall mean and be limited to NSS and NSI and shall not
include RSD, HHCA or any of their other subsidiaries.

     "Net Revenue" shall mean the Eligible Companies' consolidated net revenue
from the provision of professional nursing and related services to private pay
patients (i.e. without third party reimbursement) and from the provision of
staffing and related services to hospitals, nursing homes and other health care
providers, after deduction of all direct costs and expenses of providing such
services and an allocation of RSD overhead (which allocation shall be based on
the percentage of revenue generated by the Eligible Companies in proportion to
the total revenue generated by the Selling Companies), except for income taxes,
interest expense and allocated HHCA home office expense to RSD or the Eligible
Companies. Net Revenue shall not include revenues and related expenses arising
in connection with (i) the sale or provision of services or goods not provided
or sold by the Eligible Companies prior to the date hereof, or (ii) businesses
acquired after the date hereof. The Purchasing Parties shall endeavor to conduct
such excluded businesses through companies other than the Eligible Companies.
During the Earnout Period, the Purchasing Parties:

     (i)    shall not distribute or reallocate any revenue attributable to the
Eligible Companies;
 
     (ii)   shall manage the Eligible Companies in good faith and not with a
view towards preventing the Eligible Companies from achieving the Target Net
Revenue;

     (iii)  shall permit Seller and Salvatore DiSalvo to devote a reasonable
amount of time to the Eligible Companies subject to the terms of the Employment
Agreements; and

     (vi)   shall not materially impair the ability of the Seller to earn the
Maximum Earnout Amount, subject to HHCA Policies and Procedures (as defined in
the Employment Agreement).

     Within one hundred twenty (120) days after each calendar year referred to
above (the "Determination Period"), Purchaser and HHCA shall notify Seller in
writing of the Actual Net Revenue from the preceding calendar year and shall
provide supporting work papers.  Actual Net Revenue shall be determined in
accordance with GAAP (hereinafter defined), subject to the modifications set
forth herein.  Unless there is a disagreement among the parties, the required
Earnout Payment will be made within the Determination Period.  If Seller does
not agree with Purchaser's determination of Actual Net Revenue for any calendar
year during the Earnout Period,  Seller shall notify Purchaser and HHCA in
writing within 30 days of receipt thereof and Purchaser, HHCA and Seller shall
use reasonable efforts to resolve such dispute.  Any dispute between such
parties relating to the required Earnout Payment shall be resolved by Peat
Marwick (the "Independent Accountant") who shall be engaged to provide a final
and conclusive resolution of all unresolved disputes within thirty (30) calendar
days after such engagement.  The determination of the Independent Accountant
shall be final and binding on such parties and the 

                                      -6-
<PAGE>
 
fees and expenses of the Independent Accountant shall be borne by the party who,
in the Independent Accountant's determination, submitted a disputed amount which
differs more significantly from the amount finally determined by the Independent
Accountant.

     In the event that substantially all of the assets or stock of the Eligible
Companies is sold prior to the end of the Earnout Period, at the closing on such
sale, Purchaser and HHCA shall pay Seller an amount equal to the Maximum Earnout
Amount discounted to present value using a rate of interest equal to eight
percent (8%) less any Earnout Payments previously made to Seller; provided,
however, that such acceleration shall not be triggered by a merger of HHCA where
HHCA is the surviving entity (and Employment Agreements continue in accordance
with the terms thereof) or by a merger where HHCA is not surviving entity so
long as the surviving entity agrees in writing to continue to pay the Earnout
Payments in accordance with the terms hereof and to honor the terms of the
Employment Agreements.  In the event that Seller's or Salvatore DiSalvo's
employment under the Employment Agreements (hereinafter defined) is terminated
for any reason, the Earnout Payments, if any, will continue to be made  in
accordance with the terms hereof.

        2.3  Acquisition Price Adjustment.
             ---------------------------- 

             (a)   The Preliminary Acquisition Price shall be adjusted (the
"Acquisition Price Adjustment") upward or downward on a dollar-for-dollar basis,
as applicable, to the extent that the "Consolidated Net Book Value of RSD" (as
hereinafter defined) reflected on the Closing Date Balance Sheet is greater or
less than Sixty Thousand Dollars ($60,000) (the "Base Net Book Value"). For
purposes of this Agreement, "Consolidated Net Book Value of RSD" shall mean the
aggregate value reflected on the Closing Date Balance Sheet (determined in
accordance with generally accepted accounting principles consistently applied
("GAAP")) of the Selling Companies' (i) cash, (ii) Accounts Receivable (less
allowance for doubtful accounts and reserves for cost report disallowances and
contractual allowances)(the "Closing Date Accounts Receivable"), plus (iii)
Inventory, plus (iv) Prepaid Expenses, plus (v) Equipment and Improvements (net
of accumulated depreciation), plus (vi) the Contribution to Capital, less (vii)
cash overdrafts, less (viii) short term and long term borrowings including the
Linc Indebtedness, the Merrill Lynch Indebtedness, the Roberts Indebtedness, the
August Seller Loan and the Remaining Seller Loan, if any, less (ix) amounts due
to Medicare and other third party payors, less (x) accounts payable, accrued
expenses and other liabilities (the "Accounts Payable and Accrued Expenses") and
less (xi) customer deposits.

             (b)   For purposes of determining Consolidated Net Book Value of
RSD, (i) the Excluded Assets and the Selling Parties Expenses (hereinafter
defined, which shall be borne entirely by Seller and not the Selling Companies)
shall not be taken into account, (ii) the Linc Indebtedness, the Merrill Lynch
Indebtedness, the Roberts Indebtedness, the August

                                      -7-
<PAGE>
 
Seller Loan and the Remaining Seller Indebtedness, if any, shall be treated as
if each such loan was still outstanding and (iii) the Contribution to Capital
shall be taken into account.

             (c)   At least five (5) business days prior to Closing, Seller will
cause Simione & Simione (the "Selling Parties' Accountant") to deliver to
Purchaser a good faith estimate of the Acquisition Price Adjustment (the
"Estimated Acquisition Price Adjustment") as of September 30, 1996 adjusted to
reflect an estimate of the actual balance of any cash and indebtedness as of the
Closing. Purchaser and its accountants shall have the right to participate in
the determination of the Estimated Acquisition Price Adjustment.

             (d)   As promptly as practicable (but in no event later than ninety
(90) calendar days after the Closing Date) Seller shall cause the Selling
Parties' Accountant to prepare in accordance with GAAP (subject to the
adjustments required by this Agreement) and deliver to Purchaser and its
accountants for their review and comment (i) a consolidated balance sheet for
the Selling Companies dated as of the Closing Date (the "Closing Date Balance
Sheet"), (ii) a consolidated income statement for the Selling Companies dated as
of the Closing date (the "Closing Date Income Statement") and (iii) an
accompanying closing statement (the "Closing Statement") reasonably detailing as
of the Closing Date its final determination of each element of the Acquisition
Price Adjustment.  To facilitate the preparation of the foregoing financial
statements, the Purchaser shall provide the Selling Parties' Accountant and
Seller with reasonable and complete access to the Books and Records and to the
Selling Companies' personnel; provided, however that Purchaser and its
accountants shall have the right to participate in the preparation of the
foregoing financial statements and that such access will not unreasonably
interfere with the operations of the Selling Companies. Seller shall cause the
Selling Parties' Accountants to provide Purchaser and its accountants with such
supporting documentation as they shall reasonably request.

             (e)   If Purchaser objects to any amounts reflected on the Closing
Date Balance Sheet, the Closing Date Income Statement or the Closing Statement,
Purchaser must, within twenty (20) calendar days after Purchaser's receipt of
the Closing Date Balance Sheet, the Closing Date Income Statement and Closing
Statement, give written notice (the "Notice") to Seller specifying in reasonable
detail Purchaser's objections, or the Selling Parties' Accountant's
determination of the Acquisition Price Adjustment and the financial statements
referred to above shall be final, binding and conclusive on the parties. With
respect to any disputed amounts, the parties shall meet in person and negotiate
in good faith during the fifteen (15) calendar day period (the "Resolution
Period") after the date of Seller's receipt of the Notice to resolve any such
disputes. If the parties are unable to resolve all such disputes within the
Resolution Period, then within five (5) business days after the expiration of
the Resolution Period, all disputes shall be submitted to the Independent
Accountant who shall be engaged to provide a final and conclusive resolution of
all unresolved disputes within thirty (30) calendar days after such engagement.
The determination of the Independent Accountant shall be final, binding and

                                      -8-
<PAGE>
 
conclusive on the parties hereto, and the fees and expenses of the Independent
Accountant shall be borne by the party who, in the Independent Accountant's
determination, submitted a disputed amount which differs more significantly from
the amount finally determined by the Independent Accountant.

             (f)  If the Acquisition Price Adjustment (as finally determined in
accordance with the provisions set forth above) is a (i) positive amount, then,
within five (5) business days after such final determination, Purchaser shall
pay to Seller such amount in immediately available funds, or (ii) negative
amount, then, within five (5) business days after such final determination, the
Seller shall pay to Purchaser such amount in immediately available funds.   If
Seller fails to pay such amount, the parties shall cause the Escrow Agent to
release to Purchaser from the Escrow such unpaid amount in immediately available
funds. Notwithstanding the foregoing, all undisputed amounts shall be paid
promptly by the party responsible for the payment thereof.

        2.4  Uncollected Accounts Receivable Adjustments.  In the event
             -------------------------------------------               
that all of the Closing Date Accounts Receivable (less reserves for bad debts,
cost report disallowances and contractual allowances set forth on the Closing
Date Balance Sheet) are not fully collected by Purchaser within fifteen (15)
months after the Closing (the "Uncollected Accounts Receivable"), the parties
shall cause the Escrow Agent to release to Purchaser in immediately available
funds from the Escrow an amount equal to the Uncollected Accounts Receivable and
Seller shall promptly pay to Purchaser any remaining deficiency.  Any
Uncollected Accounts Receivable shall be assigned to Seller without recourse to
Purchasing Parties and to the extent that any such Uncollected Accounts
Receivable are collected by Purchaser or the Selling Companies after such
assignment, they shall be promptly paid over to Seller.  Purchaser shall use
commercially reasonable efforts to collect the Closing Date Accounts Receivable
in accordance with its established collection practices and policies; provided,
however, that Purchaser shall not be required to engage a collection firm or to
commence any legal action in connection therewith. Seller may pursue and collect
any Uncollected Accounts Receivable assigned to Seller. Notwithstanding the
foregoing, with respect to the collection of Medicare Uncollected Accounts
Receivable, (i) such amounts shall not be assigned to Seller, (ii) Purchaser
(with the assistance of Seller) shall appeal any such amounts which remain
unpaid after 15 months and (iii) the proceeds thereof, if any, when collected,
less the reasonable costs incurred in the collection thereof, will be paid by
Purchaser promptly to Seller.

        2.5   Unbooked Cost Adjustments.  In the event that after the Closing
              -------------------------
the Selling Companies shall incur or receive any Medicare, Medicaid, Eldercare
or other unbooked cost adjustment or audit (which is not taken into account as
part of the Acquisition Price Adjustment) with respect to any period prior to
the Closing, any such negative cost or audit adjustments shall be promptly
reimbursed by Seller and any such positive cost or audit adjustments shall be
promptly paid to Seller by Purchaser. Purchaser (with the assistance of

                                      -9-
<PAGE>
 
Seller) shall appeal any audit determinations at Seller's request, and the
proceeds thereof, if any, when collected, less the reasonable costs incurred in
the collection thereof, will be paid by the Purchaser promptly to Seller.

        2.6  Holdback Amount.  Subject to the provisions of Section 11
             ---------------                                ----------
of this Agreement, as security for the indemnities and other agreements of the
Selling Parties contained in this Agreement, on the Closing Date the Escrow
Agent shall retain the Holdback Amount, the Note and the HHCA Stock in
accordance with the terms of the Escrow Agreement.  Nothing in this Section 2.6
                                                                    -----------
or in the Escrow Agreement shall be construed as limiting the liability of the
Selling Parties under this Agreement to the amount of the Holdback Amount, the
Note or the HHCA Stock nor shall that amount be considered as liquidated damages
for any breach of this Agreement by the Selling Parties.

        2.7  The Closing.  Unless this Agreement shall have been earlier
             -----------                                                
terminated in accordance with the terms hereof, the transactions contemplated by
this Agreement shall be consummated (the "Closing") at the offices of Kleinbard,
Bell & Brecker on the last business day to fall within the ten (10) calendar day
period after receipt by Purchaser of the Regulatory Approvals (as hereinafter
defined), or at such other place or on such other date as Purchaser and Seller
may agree in writing; provided, however, that if Purchaser shall have waived the
condition that the Regulatory Approvals be granted (in accordance with the
provisions of Section 5.10), the Closing shall be consummated on the last
              ------------                                               
business day to fall within the ten (10) calendar day period after Purchaser
notifies Seller in writing of Purchaser's intention to waive such condition. The
date on which the Closing shall occur is referred to in this Agreement as the
"Closing Date". The Closing shall be deemed to have occurred as of 12:01 a.m. on
the Closing Date.

respective terms, except to the extent that enforceability may be limited by the
effect of bankruptcy,  reorganization or other similar laws relating to or
affecting the rights of creditors generally.  Except as set forth on Schedule
                                                                     --------

shall disagree with or dispute the accuracy of any Current Return, the
Purchasing Parties shall notify the Selling Parties in writing of such dispute
within thirty (30) days of the delivery of the Current Return. In connection
with the review of the Current Return, the Selling Parties shall cause the

Parties. In the event of such a dispute, the Selling Parties and the Purchasing
Parties shall attempt to reconcile their differences and any resolution by them
of any disputed amounts shall be final, binding and conclusive on the parties.
If the parties are unable to reach a resolution to such effect within twenty
(20) days of the delivery of the Purchasing Parties' written notice of the
dispute to the Selling Parties, the items

     8.   Confidentiality.
          --------------- 

               (a)    As used in this Agreement, the term "Confidential
Information" shall mean all confidential and proprietary material considered to
be confidential by any of the parties and knowledge and information not readily
available to the public heretofore or hereafter conceived, learned or disclosed
(including all documents, writings, memoranda, business plans, computer
software, reports, pricing, cost and sales information, financial statements or
condition, customer, patient, provider, referral source and supplier lists,
trade secrets, and marketing strategies, plans and techniques).

               (b)    From and after the date hereof, the Selling Parties shall
(and shall use their best efforts to cause the Related Parties to) keep secret
and retain in strictest confidence, and shall not, without Purchasing Parties'
express prior written consent, directly or indirectly, disclose, disseminate,
publish, reproduce, retain, use (for their benefit or for the benefit of others
after Closing), or otherwise make available in any manner whatsoever, any
Confidential Information regarding the Selling Companies or the Purchasing
Parties (or this Agreement or the transactions contemplated hereby) to anyone
except (i) to their representatives (who shall be informed of the confidential
nature of such information and who shall agree to keep such information
confidential), (ii) to Purchasing Parties and its affiliates or representatives,
(iii) as otherwise required by law, (iv) as required by the Selling Parties to
enforce their rights under this Agreement, or (v) as required to obtain the
Regulatory Approvals. Notwithstanding the foregoing the Selling Companies shall
be permitted to utilize their respective Confidential Information in the conduct
of the Business in the ordinary course.

               (c)    From and after the date hereof and continuing until the
Closing Date, the Purchasing Parties shall keep secret and retain in strictest
confidence, and shall not, without Seller's express prior written consent,
directly or indirectly, disclose, disseminate, publish, reproduce, retain, use
(for its benefit or for the benefit of others) or otherwise make available in
any manner whatsoever, any Confidential Information regarding the Selling
Parties (or this Agreement or the transactions contemplated hereby) to anyone
except (i) to its representatives (who shall be informed of the confidential
nature of such information and who shall agree to keep such information
confidential), (ii) as otherwise required by law, including securities laws,
(iii) as required by its lenders, (iv) as required by the Purchasing Parties to
enforce their rights under this Agreement, or (v) as required to obtain the
Regulatory Approvals.

               (d)    If any party (the "Disclosing Party") breaches, or
threatens to commit a breach of, any of the provisions of this Section 8.1, the
                                                               -----------
other party (the "Non-Disclosing Party") shall have the right (in addition to
any other rights and remedies available to the Non-Disclosing Party at law or in
equity) to equitable relief (including injunctions) against such breach or
threatened breach, it being acknowledged and agreed that any such breach or
threatened breach will cause irreparable harm to the Non-Disclosing Party and
that money


                                     -40-
<PAGE>
 
damages would not be an adequate remedy to the Non-Disclosing Party.  The
Disclosing Party agrees that it will not seek, and hereby waives any requirement
for, the securing or posting of a bond or proving actual damages in connection
with the Non-Disclosing Party's seeking or obtaining such relief.
 
     9.   Books and Records; Use of Names.
          ------------------------------- 

               (a)  Each party agrees that it will cooperate with and make
available to the other party, during normal business hours, all books and
records relating to the Business, information and employees (without substantial
disruption of employment) retained and remaining in existence after the Closing
which are necessary or useful in connection with any tax inquiry, audit,
investigation or dispute, any litigation or investigation or any other matter
requiring any such books and records, information or employees for any
reasonable business purpose.  All information received pursuant to this Section
                                                                        -------
9(a) shall be subject to the confidentiality provisions of Section 8.
- ----                                                       --------- 

               (b)  Cooperation and Records Retention.  The parties shall (i)
                    ---------------------------------
each provide the other with such assistance as may reasonably be requested by
either of them in connection with the preparation of any return, audit, or other
examination by any taxing or any other authority or judicial or administrative
proceedings relating to any liability, (ii) for a reasonable period of time,
each retain and provide the other with any records or other information that may
be relevant to such return, audit or examination, proceeding or determination,
and (iii) each provide the other with any final determination of any such audit
or examination, proceeding, or determination that affects any amount required to
be shown on any tax return or other documents of the other for any period.
Without limiting the generality of the foregoing, the parties shall each retain,
until the applicable statutes of limitations (including any extensions) has
expired, copies of all tax returns, supporting work schedules, and other records
or information that may be relevant to such returns for all tax periods or
portions thereof ending on or before the Closing Date and shall, during such
period, provide the other party with a reasonable opportunity to review and copy
the same. The parties shall also make reasonably available financial and other
information concerning the Selling Companies, as a party may from time to time
reasonably request.
 
               (c)  After the Closing Date, Seller shall not permit any Related
Party to conduct business in any location under a name confusing similar to the
name of any Selling Company.
 
     10.  Survival of Representations and Warranties. Any disclosures contained
          ------------------------------------------                           
in any Schedule or any certificate delivered pursuant to this Agreement by any
party hereto shall constitute a representation and warranty of such party.  The
representations and warranties of the Selling Parties and the Purchasing Parties
contained herein shall survive the consummation of the 

                                      -41-
<PAGE>
 
transactions contemplated hereby and the Closing Date, without regard to any
investigation made by any of the parties hereto, and shall expire three (3)
years after the Closing Date; provided, however, that the representations and
                              --------  -------    
warranties (and all claims and causes of action with respect thereto) in
Sections 3.16, 3.19, and 3.25 and claims based on fraud and obligations under
- ----------------------------- 
Sections 2.4 and 2.5 hereof shall survive the Closing Date until the expiration
of the applicable statute of limitations. The termination of the representations
and warranties provided herein shall not affect the rights of a party seeking
indemnification under this Agreement, provided that such party shall have given
written notice to the other party, prior to the expiration of the applicable
survival period provided above, of a claim for indemnification.

     11.  Indemnification.
          --------------- 

          11.1  Obligation to Indemnify by Selling Parties.  Subject to the
                ------------------------------------------                 
terms of Section 10, Selling Parties prior to the Closing and the Seller after
         ----------                                                           
the Closing, agree to indemnify, defend and hold harmless Purchasing Parties and
the Selling Companies (and their shareholders, affiliates, and their directors,
officers, stockholders and employees), from and against all losses, Taxes,
liabilities, damages, lawsuits, deficiencies, claims, demands, costs or
expenses, including interest, penalties and reasonable attorneys' fees and
disbursements ("Losses"), based upon, incurred in connection with, arising out
of or otherwise in respect of (i) any breach of any representation or warranty
of the Selling Parties contained in this Agreement or in any agreement attached
as an exhibit hereto delivered pursuant to this Agreement, (ii) any breach of
any covenant or agreement of the Selling Parties contained in this Agreement or
in any agreement attached as an exhibit hereto delivered pursuant to this
Agreement, (iii) any liability or obligation of the Selling Companies which is
not reflected and adequately reserved for on the Closing Date Balance Sheet,
except for executory liabilities under Contracts with respect to periods after
the Closing Date, or (iv) Tax Deficiencies.

          11.2  Obligation to Indemnify by Purchaser. Subject to the terms of
                ------------------------------------                      
Section 10, the Purchasing Parties agree to indemnify, defend and hold harmless
- ----------                                                            
Seller from and against all Losses based upon, incurred in connection with,
arising out of or otherwise in respect of (i) any breach of any representation
or warranty of the Purchasing Parties contained in this Agreement or in any
agreement attached as an exhibit hereto, (ii) any breach of any covenant or
agreement of the Purchasing Parties contained in this Agreement or in any
agreement attached as an exhibit hereto, (iii) any liability or obligation of
the Selling Companies to the extent reflected and adequately reserved for on the
Closing Date Balance Sheet, (iv) executory liabilities under Contracts with
respect to periods after the Closing Date or (v) any liability or obligation of
the Selling Companies arising solely out of Purchaser's operation of the
Business after the Closing.

          11.3  Losses.  The term "Losses" as used herein (i) is not limited to
                ------                                              
matters asserted by third parties against the Selling Parties or the Purchasing
Parties and includes Losses incurred or sustained in the absence of third-party
claims, (ii) includes Losses incurred through 

                                      -42-
<PAGE>
 
and after the date of the claim for indemnification (including any
Losses related thereto and suffered after the end of any applicable survival
period provided that a claim for indemnification was timely given pursuant to
Section 10), (iii) does not include any decline in value of the HHCA Stock and
- ----------
(iv) does not include consequential damages (unless awarded to a third party).

          11.4  Procedures for Claims Between the Parties.  If a claim (a
                -----------------------------------------                
"Claim") is to be made by the party claiming indemnification (the "Claimant")
against the other party (the "Indemnifying Party"), the Claimant shall give
written notice (a "Claim Notice") to the Indemnifying Party as soon as
practicable after the Claimant becomes aware of the facts, condition or event
which may give rise to Losses for which indemnification may be sought under this
Section 11.  The Claim Notice shall specify in reasonable detail the nature and
- ----------                                                                     
extent of the Claim.  Following receipt of the Claim Notice from the Claimant,
the Indemnifying Party shall have thirty (30) calendar days to make such
investigation of the Claim as the Indemnifying Party deems necessary or
desirable; provided, however, that if Claimant reasonably determines that it
           --------  -------                                                
will be materially prejudiced by affording the Indemnifying Party such period of
time for investigation, the Claimant shall so notify the Indemnifying Party and
the Indemnifying Party and the Claimant shall agree promptly on the appropriate
period of time for such investigation. For the purposes of such investigation,
the Claimant agrees to make available to the Indemnifying Party and/or its
authorized representative(s) the information relied upon by the Claimant to
substantiate the Claim. If the Claimant and the Indemnifying Party agree at or
prior to the expiration of said thirty (30) day period (or any mutually agreed
upon period or extension thereof) to the validity and amount of such Claim, the
Indemnifying Party shall pay promptly to the Claimant the agreed upon amount of
such Claim. If the Claimant and the Indemnifying Party do not agree within said
period (or any mutually agreed upon period or extension thereof), the Claimant
may seek appropriate legal remedy subject to this Section 11.
                                                  ---------- 

          11.5  Defense of Third-Party Actions.  If any lawsuit or enforcement
                ------------------------------                    
action (a "Third Party Action") is filed against a Claimant entitled to the
benefit of indemnity hereunder, written notice thereof (the "Third-Party Action
Notice") shall be given by Claimant to the Indemnifying Party as promptly as
practicable (and in any event within fifteen (15) calendar days after the
service of the citation or summons or other manner of process). The failure of
any Claimant to give notice timely hereunder shall not affect rights to
indemnification hereunder, except to the extent that the Indemnifying Party
demonstrates actual damage caused by such failure. After such notice, the
Indemnifying Party shall be entitled, if it so elects, (i) to take control of
the defense and investigation of such Third-Party Action, (ii) to employ and
engage attorneys reasonably satisfactory to the Claimant to handle and defend
the same, at the Indemnifying Party's cost, risk and expense, and (iii) to
compromise or settle such Third-Party Action, which compromise or settlement
shall be made only with the written consent of the Claimant, such consent not to
be unreasonably withheld, conditioned or delayed. If the Indemnifying Party
fails to assume the defense of such Third-Party Action at its cost within
fifteen (15) calendar days after receipt of the Third-Party Action Notice, the
Claimant will (upon

                                      -43-
<PAGE>
 
delivering notice to such effect to the Indemnifying Party) have the right to
undertake, at the Indemnifying Party's cost and expense, the defense, compromise
or settlement of such Third-Party Action on behalf of and for the account and
risk of the Indemnifying Party; provided, however, that such Third-Party Action
                                --------  -------
shall not be compromised or settled, nor shall an entry of judgment be agreed
to, without (i) the written consent of the Indemnifying Party, which consent
shall not be unreasonably withheld, conditioned or delayed and (ii) an
unconditional release of the Claimant and the Indemnifying Party. In the event
the Claimant assumes the defense of the Third-Party Action, the Claimant will
keep the Indemnifying Party reasonably informed of the progress of any such
defense, compromise or settlement. The Indemnifying Party shall be liable for
any settlement of any Third-Party Action effected pursuant to and in accordance
with this Section 11 and for any final judgment (subject to any right of
          ----------
appeal), and the Indemnifying Party agrees to indemnify and hold harmless
Claimant from and against any Losses by reason of such settlement or judgment.

          11.6  Limitation of Indemnification.  The Indemnifying Party's
                -----------------------------                           
obligations to indemnify the Claimant pursuant to this Section 11 shall be
                                                       ----------         
subject to the following limitations:

                (a) No indemnification shall be required to be made by the
Indemnifying Party until the aggregate amount of the Claimant's Losses (which
Losses shall include Losses relating to any representation or warranty qualified
by reference to materiality or to a material adverse change even if such Loss
does not in and of itself result in a breach of such representation or warranty)
exceeds $100,000 (the "Basket"), and then indemnification shall only be required
by the Indemnifying Party to the extent of such excess. Notwithstanding the
foregoing, the limitation imposed by the Basket shall not apply to (i) the
Acquisition Price Adjustment, or (ii) breaches of the provisions of Sections
                                                                    --------
2.4, 2.5 or 13.4.
- ---------------- 

                (b) No indemnification shall be required to be made by the
Indemnifying Party under this Section 11 for the amount of the Claimant's Losses
                              ----------                                        
that are in excess of $2,000,000, except with respect to (i) breaches of the
provisions of Sections 2.4 or 2.5 which will be subject to a separate limitation
              -------------------                                               
in the amount of the Closing Date Accounts Receivable (less allowance for
doubtful accounts, and reserves for cost report disallowances and contractual
allowances reflected on the Closing Date Balance Sheet) which amount shall be
reduced by Accounts Receivable actually collected by the Purchaser after the
Closing, (ii) the Acquisition Price Adjustment which is not subject to a
limitation, and (iii) Losses incurred in connection with undisclosed liabilities
which are subject to a separate limitation in the amount of $3,500,000 for
Claims asserted during the first 15 months after Closing and $2,000,000 for
Claims asserted thereafter.

                (c) The indemnification obligation of an Indemnifying Party
shall be adjusted so as to give effect to any net reduction in federal, state,
local or foreign income or franchise tax liability actually realized at any time
by the Claimant in connection with the

                                      -44-
<PAGE>
 
satisfaction by the Indemnifying Party of a Claim with respect to which
indemnification is sought hereunder. Any Claims payable by the Indemnifying
Party to the Claimant hereunder shall also include the federal, state, local or
foreign income or franchise tax liability that the Claimant will incur upon the
receipt of payment in respect of such Claims (taking into account any net
operating loss, capital loss or credit carryover of the Claimant); however, with
respect to any Claims for which the Claimant (but for the operation of this
sentence) is entitled to indemnification hereunder, there shall be disregarded
any tax liabilities arising by reason of (i) any reduction or disallowance of
deductions from taxable income in one taxable year, but only to the extent such
reduction or disallowance actually results in a corresponding increase in
allowable deductions from income in another year, (ii) the shifting of items of
income from one taxable year to another, or (iii) the capitalization of amounts
that were expended, but only if such capitalized amounts are subject to
amortization or depreciation or recovery in costs of goods sold, inventory or
materials, except insofar as such reduction, disallowance, shifting or
capitalization would only result in the increase of any unutilized net operating
loss, capital loss or carryover. The indemnification obligation of an
Indemnifying Party with respect to any Claim shall also be adjusted to take into
account the amount, if any, of any insurance proceeds recovered by the Claimant
as a result of such Claim, after the deduction of all costs incurred to obtain
such proceeds.

          11.7  Exclusive Remedy.  The remedies provided under this Agreement
                ----------------                                   
shall constitute the sole and exclusive remedy of the parties hereto for any
breach of representation or warranty contained in this Agreement or in any of
the agreements attached as Exhibits hereto or for any breach or covenant of or
failure to perform any covenant contained in this Agreement or in any of the
agreements attached as Exhibits hereto and the parties waive any other remedy
which they or any other person entitled to indemnification hereunder may have at
law or in equity with respect thereto; provided, however that this exclusion
shall not apply to Claims based on fraud.

     12.  Breaches and Defaults; Termination; Remedies.
          -------------------------------------------- 

          12.1  Termination.  This Agreement may be terminated at any time
                -----------                                               
prior to the Closing as follows:

                (a) by mutual written agreement of the parties hereto;

                (b) provided the Purchasing Parties are not then in breach of
this Agreement, at the election of the Purchasing Parties (pursuant to a written
notice to the Selling Parties), (i) if any one or more of the conditions to the
Purchasing parties' obligations to close has not been fulfilled in any material
respect as of the Closing Date, (ii) if the conditions set forth in Sections
                                                                    --------
6.19 (Board Approval), 6.20 (Lender Approval) or 6.21(Due Diligence
- -------------------------------------------------------------------
Investigation) are not satisfied; provided, however, that these conditions shall
- --------------
expire as provided therein, (iii) if

                                      -45-
<PAGE>
 
any of the Selling Parties have breached in any material respect any
representation, warranty, covenant or agreement contained in this Agreement or
in any other agreement or document delivered pursuant hereto, or (iii) if the
Closing shall not have taken place by December 31, 1996 (the "Outside Date")
(unless any of the foregoing events shall have resulted primarily from the
Purchasing Parties breaching any representation, warranty, covenant or agreement
contained in this Agreement);

                (c) provided the Selling Parties are not then in breach of this
Agreement, at the election of the Selling Parties (pursuant to a written notice
to the Purchasing Parties), (i) if any one or more of the conditions to the
Selling Parties' obligations to close has not been fulfilled in any material
respect as of the Closing Date, (ii) if the Purchasing Parties have breached in
any material respect any representation, warranty, covenant or agreement
contained in this Agreement or in any other agreement or document delivered
pursuant to hereto, or (iii) if the Closing shall not have taken place by the
Outside Date (unless any of the foregoing events shall have resulted primarily
from the Selling Parties' breach of any representation, warranty, covenant or
agreement contained in this Agreement); and

                (d) in accordance with the terms of Sections 5.8 or 13.8.
                                                    -------------------- 

          12.2  Effect of Termination.  In the event of any termination of
                ---------------------                                     
this Agreement, all obligations of the parties hereto under this Agreement shall
terminate as of such date of termination and this Agreement shall thereafter
become void and be of no further force and effect, and upon such termination no
party hereto shall be liable to the other party; provided however, that (i) the
obligations contained in Sections 8 and 11 shall survive any termination hereof,
                         -----------------                                      
and (ii) the foregoing provisions shall not limit or restrict the availability
of specific performance (as provided in Section 12.3) or other injunctive relief
                                        ------------                            
to the extent that specific performance or such other relief would otherwise be
available to a party hereunder.

          12.3  Specific Performance.  The Selling Parties agree that the Shares
                --------------------                                     
and the Business are unique assets that cannot be readily obtained on the open
market and that the Purchasing Parties will be irreparably injured if this
Agreement is not specifically enforced. Therefore, notwithstanding anything to
the contrary contained herein or otherwise, prior to the consummation of the
Closing, the Purchasing Parties shall have the right to enforce specifically the
Selling Parties' performance under this Agreement, and the Selling Parties waive
any defense in any such suit that the Purchasing Parties have an adequate remedy
at law and to interpose no opposition, legal or otherwise, as to the propriety
of specific performance as a remedy. The remedies described in this Section 12.3
                                                                    ------------
shall be in addition to, and not in lieu of, any other remedies that the
Purchasing Parties may elect to pursue.

                -----------------------                          
hereof, each of the parties hereto (i) submits and consents to the personal

(iii) waives the right to object that any such court does not have personal
jurisdiction over such party, and (iv) consents to the service of process in any
such suit, action or proceeding upon the receipt through the United States mail
of copies of such process to such party by certified mail to the addresses
indicated herein or at such other addresses of which the other parties shall
have received written notice. Nothing herein shall pre clude any party from
bringing suit or taking other legal action in any other jurisdiction or from
serving legal process in any other manner permitted by law or in equity.

          13.2  Expenses.  The parties to this Agreement shall bear their
                --------

execution and performance of this Agreement and the transactions contemplated
hereby, including all fees and expenses of agents, representatives, consultants,
counsel and accountants. The Selling Parties shall pay in full all such expenses
at or prior to the Closing (the "Selling Parties' Expenses").  Notwithstanding
the foregoing, at the Closing the Purchasing Parties shall pay the audit
expenses incurred by the Selling Companies for services performed by the Selling
Parties' Accountant solely with respect to the audit of the Selling Companies'
financial statements for the year ended June 30, 1996 (excluding the audit
expense incurred in auditing NSL's June 30, 1996 financial Statements) and the
preparation of the Closing Date Balance Sheet, the Closing Date Income Statement
and the Closing Statement, which in each case, will not be considered to be
Selling Parties' Expenses.

          13.3  Further Assurances.  Each of the parties shall execute such
                ------------------                                         
agreements and documents and take such further actions as may be reasonably
required or desirable to carry out the provisions hereof and the transactions
contemplated hereby.  Each such party shall use its reasonable best efforts to
fulfill or obtain the fulfillment of the conditions to the Closing, including
the execution and delivery of any other agreement or document, the execution and
delivery of which are conditions precedent to the Closing.

          13.4  Indemnification for Brokerage.  The Selling Parties agree to
                -----------------------------                            
indemnify and save the Purchasing Parties harmless from any claim or demand for
commissions or other compensation by any broker, finder, agent or similar
intermediary claiming to have been employed by or on behalf of the Selling
Parties and to bear the cost of legal fees and expenses incurred in defending
against any such claim. The Purchasing Parties agree to indemnify and save the
Selling Parties harmless from any claim or demand for commissions or other

                                      -47-
<PAGE>
 
compensation by any broker, finder, agent or similar intermediary claiming to
have been employed by or on behalf of the Purchasing Parties and to bear the
cost of legal fees and expenses incurred in defending against such claim. The
Selling Parties shall pay any commission due to Advest.

          13.5  Severability.  Any provision of this Agreement which is
                ------------                                           
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.  If any court determines
that any covenant, or any part of any covenant is invalid or unenforceable, such
covenant shall be enforced to the extent permitted by such court, and all other
covenants shall not thereby be affected and shall be given full effect, without
regard to the invalid portions.

          13.6  Notices.  Any notice or other communication required or 
                -------

                ----------------                                          
Exhibits) and the agreements, certificates and other documents delivered

          13.8  Disclosure Schedules; Independent Significance.
                ---------------------------------------------- 

                (a) The parties acknowledge and agree that (i)the parties have
not yet completed the Schedules to this Agreement; and (ii) the failure to
complete the Schedules prior to signing this Agreement shall not constitute a
waiver of any parties' right to require that the Schedules be completed and
attached. Selling Parties shall as promptly as possible complete the Schedules
and submit the same to the Purchasing Parties for their review on or before 5:00
P.M. on Tuesday, November 5, 1996.

                (b) In the event that any of the Schedules delivered to the

Parties, the Purchasing Parties shall have the right to terminate this Agreement
by giving Seller written notice thereof within 5 days after receipt of
Schedules.

                (c) Nothing in any Schedule hereto shall be deemed adequate to
disclose an exception to a representation or warranty made herein unless the
Schedule identifies the exception with reasonable particularity. The parties
intend that each representation, warranty, covenant and agreement contained
herein shall have independent significance; accordingly, if any party has
breached any representation, warranty, covenant or agreement, the fact that
there

                                      -49-
<PAGE>
 
exists another representation, warranty, covenant or agreement relating to

or mitigate the fact that the party is in breach of the first representation,
warranty, covenant or agreement.

          13.9   Amendments and Waivers.  This Agreement may be modified or
                 ----------------------                                    
amended, and the terms hereof may be waived, only by a written instrument signed
by the parties or, in the case of a waiver, by the party waiving compliance.  No
delay on the part of any party in exercising any right, power or privilege
hereunder shall operate as a waiver thereof, nor shall any waiver on the part of
any party of any such right, power or privilege, nor any single or partial
exercise of any such right, power or privilege, preclude any further exercise
thereof or the exercise of any other such right, power or privilege.

          13.10  Governing Law.  This Agreement shall be governed and
                 -------------

law) by any party without the prior written consent of the other party, except
that Purchaser may, without such consent, assign any and all such rights and
obligations to any affiliate, provided that Purchasing Parties shall remain
liable for the discharge of such obligations. Subject to the foregoing, this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and permitted assigns.

          13.12  Joint and Several.  HHCA hereby guarantees all of the
                 -----------------

Selling Party, on the one hand, and each Purchasing Party, on the other hand,
under this Agreement, shall be joint and several.

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

the other party hereto and are not intended to benefit, and may not be relied

     RE:  Amendment to Stock Purchase Agreement and Promissory Note

Dear Randy:

     Reference is made to (i) that certain "Stock Purchase Agreement" dated
October 31, 1996 among each of the parties listed above, Home Health Corporation
of America, Inc. ("HHCA") and HHCA New Hampshire, Inc. and (ii) that certain
"Promissory Note" dated August 8, 1996 given by Randy DiSalvo in favor of HHCA.
Capitalized terms not otherwise defined herein shall have the meanings given
such terms in the Stock Purchase Agreement.  The purpose of this Amendment is to
memorialize our entire agreement and understanding concerning the amendment of
the Stock Purchase Agreement and the Promissory Note which is as follows:

     1.   The parties have agreed to provide the Purchasing Parties with
additional time in which to review and accept the schedules to the Stock
Purchase Agreement.  Accordingly, in Section 13.8(b) of the Stock Purchase
Agreement, the phrase "within 5 days after receipt of the Schedules" is hereby
deleted and replaced with the phrase "on or before 5:00 P.M. on Friday, November
15, 1996".

     2.   The parties have agreed to amend the maturity date of the Promissory
Note. In Section 3(ii) of the Promissory Note, the phrase "Letter of Intent" is
hereby deleted and replaced with the phrase "Stock Purchase Agreement dated
October 31, 1996 among Creditor, Debtor and Guarantors". The Selling Parties
acknowledge their obligations under the Promissory Note which will be repaid in
accordance with its terms.

     3.   Creditor waives any defaults under the Promissory Note caused by
defaults by a Selling Party under its third party loan agreements; provided,
however, that such defaults do not result in the acceleration of a material
portion of such obligations and the election by such third party to pursue any
                            ---                                               
remedy against a Selling Party that would have a material adverse effect on a
Selling Party or their ability to repay the Promissory Note.

     4.   The Stock Purchase Agreement and Promissory Note as modified by this
Amendment are hereby ratified and confirmed.  In the event of any conflict
between this Amendment and the terms of the Stock Purchase Agreement or the
Promissory Note, the terms of this Amendment shall govern and

     RE:  Second Amendment to Stock Purchase Agreement

Dear Randy:

     Reference is made to (i) that certain "Stock Purchase Agreement" dated
October 31, 1996 among each of the parties listed above,  Home Health
Corporation of America, Inc. ("HHCA") and a subsidiary of HHCA, as amended by an
amendment dated November 8, 1996 (as amended the "Stock Purchase Agreement").
Capitalized terms not otherwise defined herein shall have the meanings given
such terms in the Stock Purchase Agreement.  The purpose of this Amendment is to
memorialize our entire agreement and understanding concerning the amendment of
the Stock Purchase Agreement which is as follows:

     1.   The parties have agreed to provide the Purchasing Parties with
additional time in which to review and accept the schedules to the Stock
Purchase Agreement.  Accordingly, in Section 13.8(b) of the Stock Purchase
Agreement, the date "November 15, 1996" is hereby replaced with the date
"November 26, 1996".

     2.   The parties have agreed to provide the Purchasing Parties with
additional time in which to obtain Lender Approval.  Accordingly, in Section
6.20 of the Stock Purchase Agreement, the date "November 22, 1996" is hereby
replaced with the date "November 27, 1996".

     3.   The parties have agreed to provide the Purchasing Parties with
additional time in which to complete their Due Diligence Investigation.
Accordingly, in Section 6.21 of the Stock Purchase Agreement, the date "November
30, 1996" is hereby replaced with the date "December 4, 1996".

     4.   All references to HHCA New Hampshire, Inc., a New Hampshire
corporation are replaced with Home Health Corporation of Delaware, Inc., a
Delaware corporation, which by virtue of its execution hereof, assumes all of
the obligations of Purchaser under the Stock Purchase Agreement.

 
     5.   After the Closing, the Purchasing Parties shall provide Seller (i) on
a monthly basis with documentation showing the Closing Date Accounts Receivable
which have been collected during the

previous month and (ii) with reasonable access to books and records pertaining
to the Closing Date Accounts Receivable and any reports generated with respect
thereto.  Closing Date Accounts Receivable will be processed by RSD until such
time as RSD has been provided with a computer terminal providing it with the
collection information and receivable runs.

     6.   After the Closing, Seller will pay the premiums for malpractice
insurance currently maintained by the Selling Companies until such policies
expire in the Spring of 1997.  Immediately prior to the expiration of such
policies, Seller will obtain at Seller's expense continuing malpractice
insurance coverage (known as tail coverage) for the preceding three year period.

     7.   The Stock Purchase Agreement as modified by this Amendment is hereby
ratified and confirmed.  In the event of any conflict between this Amendment and
the terms of the Stock Purchase Agreement, the terms of this Amendment shall
govern and control.

     8.   In the event that Closing occurs on a date other than November 30,
1996, the parties acknowledge and agree that for financial reporting purposes,
the Closing will be considered to have occured as of the close of business on
November 30, 1996 and the Closing Date Balance Sheet, the Closing Date Income
Statement, the Closing Statement and the Purchase Price Adjustment shall be
determined as of such date. In all other respects, the Closing shall been deemed
to have occurred on the actual date of Closing.

     Please acknowledge your agreement to be legally bound by this Amendment by
signing the enclosed copy where indicated below and returning the same to the

(as hereinafter defined) of Seller (as reflected on the Closing Date Balance
Sheet (as hereinafter defined)) is less than $50,000 (the "Required Closing Date

parties. With respect to any disputed amounts, the parties shall meet in person
and negotiate in good faith during the five (5) business day period (the

disputes within the Resolution Period, then within five (5) business days after

Independent Accountant shall be final, binding and conclusive on the parties
hereto, and the fees and expenses of the Independent Accountant shall be borne
by the party that the Independent Accountant determines is the non-prevailing
party.

Estimated Minimum Assets Deficiency, Seller shall pay such shortfall (together
with interest at the rate of eight percent (8%) from the Closing Date) to
Purchaser within five (5) days after its final determination pursuant to this

          (a)  HHCA has delivered to Seller copies of HHCA's audited balance
sheet and income statement as of June 30, 1996 (collectively, the "Financial
Statements"). As used herein, the term "HHCA Balance Sheet Date" shall mean June

Balance Sheet Date that have not been paid or discharged since the date thereof,
and (ii) liabilities incurred since the HHCA Balance Sheet Date in the ordinary

their respective employees; nor, to their knowledge, are there any facts upon
which any such Action may reasonably be expected to be based, except for such
Actions that have not had and would not reasonably be expected to have a

there has been no material adverse change in the business, operations, condition
(financial or otherwise), or prospects of the Purchasing Parties and, to the
knowledge of Purchasing Parties, no such change is threatened. Since the HHCA
Balance Sheet Date, the Purchasing Parties have conducted their respective
businesses only in the ordinary course and there has been no damage, destruction
or loss materially adversely affecting the business, operations or condition
(financial or otherwise) of the Purchasing Parties, whether or not covered by

Purchasing Parties contained in this Agreement, in any Schedule or Exhibit, or
any agreement or document delivered under this Agreement or in connection
herewith contains or will contain any untrue statement of a material fact or
omits to state a material fact necessary to make the statements contained herein

Seller that could reasonably be expected to have a material adverse effect on
the ability of the Purchasing Parties to perform this Agreement.

be deemed to cure any violation or breach of any such representation, warranty,
covenant, agreement or provision), or (iii) any event, occurrence, transaction
or other item that would have been required to have been disclosed on any
Schedule delivered hereunder, had such event, occurrence, transaction or item
existed on the date hereof.

     5.2  Access to Information.  From and after the date hereof, the
          ---------------------                                      
Purchasing Parties shall be entitled, through their employees and
representatives, to make such investigation of the assets, properties,
facilities, personnel, business and operations of the Business and such
examination of the books, records and financial condition of the Business as
Purchaser reasonably requests, and Seller shall fully cooperate with Purchaser
in connection with such investigation.  No investigation by Purchaser shall
diminish, obviate, constitute a waiver as to the enforcement of, or affect
Purchaser's right to rely on, any of the representations, warranties, covenants
or agreements of Seller under this Agreement.

     5.3  Governmental Permits and Approvals; Consents.  Seller shall use its
          --------------------------------------------                       
best efforts to obtain promptly (a) all permits and approvals from any
governmental or regulatory body required to be obtained by Seller for lawful
consummation of the Closing, (b) the consents set forth or required to be set
forth on Schedule 3.11 and (c) appropriate estoppel representation letters in
         -------------                                                       
form and substance reasonably satisfactory to Purchaser from the lessors under
the Real Property Leases.  The Purchasing Parties will fully cooperate in
connection with Seller's obtaining of such permits, approvals, consents and
estoppel letters, including without limitation, by providing any necessary
documents and information.

     5.4  Maintenance of Permits.  Seller shall at all times prior to the
          ----------------------                                         
Closing Date preserve and maintain each of the material Permits free and clear
of all liens and other encumbrances.  Seller shall not take any action that
would cause any governmental or regulatory body to institute proceedings
regarding any material Permit or take any other action that would result in
Seller being in noncompliance in any material respect with the requirements of
or any governmental or regulatory body having jurisdiction thereof that would
impair Seller's qualifications to be the assignor of such Permits or Purchaser's
rights with respect thereto.

     5.5  Employees; Employee Compensation.
          -------------------------------- 

          (a)  Purchaser has informed Seller that Purchaser may offer employment
on an "at will" basis to certain employees of LHS, Holdings and Nurses
(collectively, " Employees") immediately after the Closing. Immediately prior to
Closing, Seller shall terminate the employment of all Employees that Purchaser
intends to hire. Seller waives any claims against Purchaser or any Employees
arising from such employment (including arising from any employment agreement or
noncompetition agreement). Nothing contained in this Agreement shall confer upon
any Employee


                                     -18-
<PAGE>
 
any right with respect to continued employment by Seller or Purchaser.  No
provision of this Agreement shall create any third-party rights in any Employee,
or any beneficiary or dependent thereof, with respect to the compensation, terms
and conditions of employment and benefits that may be provided to such  Employee
by Purchaser or under any benefit plan that Purchaser may maintain.
Notwithstanding anything to the contrary in this Section 5.5(a), Purchaser will
                                                 --------------

form of Exhibit 5.5 (collectively, the "Employment Agreements"), the following

employees of Seller: April Anthony, Maura Coriston, Amy Figgins and Gene Schulle
(collectively, the "Executives").

          (b)  Seller agrees to discharge when due all liabilities to any
employee of the Business under all pay and compensation practices applicable to
the Business and under any employment agreements entered into prior to the
Closing Date. Seller shall pay all severance costs in respect of employees
severed prior to the Closing Date.

     5.6  Accounts Receivable.  Between the date hereof and the Closing Date,
          -------------------                                                
Seller will use prudent credit and collection procedures in order to collect the
Accounts Receivable so as not to jeopardize Purchaser's future customer,
patient, provider and third-party payor relations.

     5.7  Title; Risk of Loss.  Legal title and risk of loss with respect to
          -------------------                                               
the Purchased Assets shall not pass to Purchaser until the Purchased Assets are
transferred at the Closing.  If prior to the Closing Date any of the Purchased
Assets are destroyed or damaged by fire or other casualty, or are otherwise
unable to be conveyed to Purchaser at the Closing, Purchaser may, at its option,
(i) require that Seller replace or restore such property; or (ii) elect to
receive at the Closing a reduction in the Preliminary Acquisition Price in an
amount reasonably estimated by Purchaser to replace or repair such property.

     5.8  Regulatory Approvals.  The parties agree that in order to consummate
          --------------------                                                
the transactions contemplated hereby, all material federal, state and local
governmental or regulatory approvals (collectively, the "Regulatory Approvals")
must be obtained, subject to Purchaser's right to waive in writing this
condition on behalf of the parties.

     5.9  Refunding to Seller of Certain Prepaid Expenses. Notwithstanding
          -----------------------------------------------                 
anything to the contrary contained in Section 1.2, Purchaser agrees that in the
                                      -----------                              
event that any of the Prepaid Expenses set forth on Schedule 5.9 are refunded to
                                                    ------------                
the Purchaser after the Closing Date, it will pay such amounts over to Seller.

Agreement, the Selling Parties have not delivered to the Purchasing Parties the
Schedules to this Agreement (and supporting agreements and documents) that are
required to be delivered hereunder by the Selling Parties ("Selling Parties'
Disclosure Schedules").  Within ten (10) business days after the date hereof,
the Selling Parties will deliver a complete set of Selling Parties' Disclosure
Schedules to the Purchasing Parties, who shall then have five (5) business days
after receipt of Selling Parties' Disclosure Schedules to review the same and to
either advise the Selling Parties that the Selling Parties' Disclosure Schedules
are acceptable or, if not, to provide comments thereon to the Selling Parties.

                                     -19-

If the Purchasing Parties do not so advise or provide comments to the Selling
Parties within such five (5) business day period, the Purchasing Parties shall
be deemed to have accepted the Selling Parties' Disclosure Schedules.  With
respect to any disagreement over the Selling Parties' Disclosure Schedules, the
parties shall negotiate in good faith during the five (5) business day period
after the date of the Selling Parties' receipt of the Purchasing Parties'
comments to discuss such comments and to attempt to reach agreement concerning
the Selling Parties' Disclosure Schedules.  If the parties are unable to reach
agreement, the Purchasing Parties shall have the right, in their sole
discretion, to terminate this Agreement at any time during such negotiation
period if the Selling Parties' Disclosure Schedules are not acceptable to the
Purchasing Parties.  The Selling Parties agree that during the Purchasing
Parties' review of the Selling Parties'  Disclosure Schedules, Purchaser may
elect not to assume certain of the contracts or other agreements that are listed
thereon.

                     -----------

Purchased Assets.  To the extent that Seller or any Related Party owns any
assets that are useful to the Business, but which do not constitute Purchased
Assets, Seller shall, if requested by Purchaser, grant (or, with respect of any
Related Party, cause any such Related Party to grant) Purchaser an irrevocable,

          (b)   At least two (2) business days prior to the Closing, Seller will

recognized accounting firm mutually acceptable to the parties (the "Independent
Accountant") who shall be engaged to provide a final and conclusive resolution
of all unresolved disputes within twenty (20) business days after such
engagement. The determination of the Independent Accountant shall be final,
binding and conclusive on the parties hereto, and the fees and expenses of the
Independent Accountant shall be borne by the party that the Independent
Accountant determines is the non-prevailing party.

          (d)   If the Minimum Assets Deficiency, if any, is greater than the
Estimated Minimum Assets Deficiency, Seller shall pay such shortfall (together
with interest at the rate of eight percent (8%) from the Closing Date) to
Purchaser within five (5) days after its final determination pursuant to this
Section 2.4. Seller and Purchaser agree not to assert, in connection with any 
- -----------  
tax return, tax audit or similar proceeding, any allocation of the Acquisition
Price that differs from that determined pursuant to this section.

Period, then within five (5) business days after the expiration of the Pre-
Closing Resolution Period, all disputes shall be submitted to the Independent

     NOW, THEREFORE, in consideration of the foregoing Background and the mutual
covenants and agreements contained herein, the parties hereto, intending to be
legally bound hereby, agree as follows:

1.   Covenants of the Parties.
     ------------------------ 

     1.1  Non-Solicitation.  From the date hereof until the closing under the
          ----------------                                                   
PDN/MIV Acquisition Agreement (the "PDN/MIV Closing"), neither the Selling
Parties nor any Related Party will, directly or indirectly, solicit, initiate,
encourage, entertain or participate in discussions or negotiations, enter into
any agreements relating to, or consummate any transaction with respect to any
Third-Party Proposal with any person other than the Purchasing Parties or the
Purchasing Parties' representatives.  During such period, Seller shall promptly
inform the Purchasing Parties of the occurrence of a Third-Party Proposal and
the terms thereof (including the identity of the prospective purchaser or
soliciting party).

     1.2   Management Agreement. At the closing under the LHS/Holdings
           --------------------                                       
Acquisition Agreement (the "LHS/Holdings Closing"), PDN and MIV will enter into
a Management Agreement with HHCA pursuant to which HHCA will manage PDN and MIV
during the period commencing on the date of the LHS/Holdings Closing and ending
on the date of the PDN/MIV Closing substantially on the terms set forth on
Exhibit 1.2 (the "Management Agreement").
- -----------                              

     1.3  Public Offering.  HHCA filed with the Securities and Exchange
          ---------------                                              
Commission ("SEC") on November 1, 1996 a registration statement for an
underwritten public offering (the "Public Offering") of shares of common stock
of HHCA ("Registration Statement").  Each of HHCA's nominees and the Selling
Parties shall use all reasonable efforts to assist HHCA in having the
Registration Statement declared effective under the Securities Act of 1933, as
amended ("Securities Act"), as promptly as practicable after such filing.  The
Purchasing Parties and the Selling Parties shall cooperate to take any action
required to be taken under any applicable state securities or "blue sky" laws in
connection with the Public Offering.  The Selling Parties shall furnish promptly
to HHCA and its counsel for inclusion in any prospectus and the Registration
Statement in connection with the Public Offering in a form reasonably
satisfactory to HHCA and its counsel, such information concerning each of
Holdings, LHS, Nurses, PDN and MIV, its respective operations, capitalization,
stock ownership, financial statements, businesses, assets and other matters as
HHCA or its counsel may reasonably request in connection with the Public
Offering, including without limitation, audited financial statements (including
pro formas) for any period prior the date of the PDN/MIV Closing. The Purchasing
Parties agree to reimburse the Selling Parties (in an amount not to exceed
$50,000) for the reasonable fees and expenses of the Selling Parties'
independent certified public accounting firm for its work in connection with the
Registration Statement. The information supplied by any of the Selling Parties
to be included in the Registration Statement or in any prospectus made a part
thereof, or in any amendments thereof or supplements thereto, will not, taken as
a whole, at the date the Registration Statement (or on the date of any
amendments thereof or supplements thereto) is declared effective by the SEC and
on the closing of the Public Offering, (i) contain any statement that, at such
time and in light of the circumstances under which it was made, will be false or
misleading with respect to any material fact, or (ii) omit to state any material
fact 

                                       2
<PAGE>
 
required to be stated therein or necessary in order to make the statements made
therein not misleading or necessary to correct any statement in any earlier
communication with respect to the Public Offering that has become false or
misleading.

     1.4   Winding-Up of LHS, Nurses, PDN and MIV.  Notwithstanding anything to
           --------------------------------------                              
the contrary contained herein or in the Employment Agreements, the Purchasing
Parties shall permit each of the Executives to devote such time during regular
business hours as may be reasonably necessary to the winding-up of LHS and
Nurses (commencing on the date of the LHS/Holdings Closing) and the winding-up
of PDN and MIV (commencing on the date of the PDN/MIV Closing) with respect to
billings, collection of Accounts Receivable, preparation of cost reports, cost
report audits and related managerial and administrative duties; provided that:
(i) such activities do not, in the Purchasing Parties' reasonable opinion,
interfere in any material respect with the performance of Executives' duties
under the Employment Agreements; (ii) the Executives use their best efforts to
give priority to their HHCA-related work in the event of a conflict; and (iii)
Executives shall not be permitted to devote time to such duties during regular
business hours after the conclusion of the final procedural step with respect to
any third-party reimbursement program audit for any period  prior to the date of
the LHS/Holdings Closing.

     1.5   Confidentiality.
           --------------- 

           (a)   As used in this Agreement, the term "Confidential Information"
shall mean all confidential and proprietary knowledge and information not

statements, customer lists, provider lists, patient lists, referral source and
supplier lists, trade secrets, discoveries, ideas, concepts, models, prototypes,
diagrams and marketing strategies, plans and techniques).

           (b)   From and after the date hereof, the Selling Parties shall (and
shall use their respective best efforts to cause the Related Parties to) keep
secret and retain in strictest confidence, and shall not, without the Purchasing
Parties' express prior written consent, directly or indirectly, disclose,
disseminate, publish, reproduce, retain, use (for their benefit or for the
benefit of others), or otherwise make available in any manner whatsoever, any
Confidential Information regarding the Selling Parties or the Purchasing Parties
(or the Acquisition Agreements, this Agreement or the transactions contemplated
hereby) to anyone except (i) to their representatives (who shall be informed of
the confidential nature of such information and who shall agree to keep such
information confidential), (ii) to the Purchasing Parties and their affiliates
or representatives, (iii) as otherwise required by law, including securities
laws, (iv) as required by the Selling Parties to the extent necessary to enforce
their rights or to enjoy any benefit under this Agreement or the Acquisition
Agreements including, by way of illustration and not limitation, to collect
accounts receivable, to make such filings with third-party payors as may be
appropriate, to defend program audits and the like, or (v) as required to obtain
the Regulatory Approvals or any consents that are required for consummation of
the transactions contemplated by the Acquisition Agreements; provided, however,
that prior to the date of the LHS/Holdings Closing the Selling Parties shall be
permitted to use such Confidential Information as may be necessary to conduct
the Business in the ordinary course and 

                                       3

benefit, under this Agreement or the Acquisition Agreements; and provided
further that during the period from the date of the LHS/Holdings Closing until
the date of the PDN/MIV Closing, the Selling Parties shall be permitted to use
such Confidential Information relating to PDN and MIV as may be necessary to
conduct the portion of the Business conducted by PDN and MIV in the ordinary
course and thereafter to do so as may be required to enforce their rights, or to
enjoy any benefit, under this Agreement or the Acquisition Agreements.

           (c) From and after the date hereof and continuing until the date of
the LHS/Holdings Closing (with respect to any Confidential Information regarding
the Selling Parties) and from and after the date of the LHS/Holdings Closing
until the date of the PDN/MIV Closing (with respect to Confidential Information
regarding PDN and MIV), the Purchasing Parties shall keep secret and retain in
strictest confidence, and shall not, without the Selling Parties' express prior
written consent, directly or indirectly, disclose, disseminate, publish,
reproduce, retain, use (for its benefit or for the benefit of others) or
otherwise make available in any manner whatsoever, any Confidential Information
regarding the Selling Parties (or the Acquisition Agreements, this Agreement or
the transactions contemplated hereby) to anyone except (i) to its
representatives (who shall be informed of the confidential nature of such
information and who shall agree to keep such information confidential), (ii) as
otherwise required by law, including securities laws, (iii) as required by its
lenders or underwriters, (iv) as required by the Purchasing Parties to enforce
their rights under this Agreement, or (v) as required to obtain the Regulatory

dissemination describing the Acquisition Agreements, this Agreement and the
transactions contemplated herein.

     1.6   Restrictive Covenant. Each of the Selling Parties acknowledges that
           --------------------                                               
(a) Holdings', LHS's, Nurses', PDN's and MIV's ownership of the Business and the
Shareholder's ownership of stock of Holdings, PDN and MIV and Shareholder's

brought each of them in close contact with certain confidential and proprietary
information of the Business (including the Confidential Information) not readily
available to the public; and (b) the Purchasing Parties would not purchase the

                   -----------

           (ii)  call on or solicit or divert or take away from Purchasing

on behalf of the Selling Parties or any third party, any persons who are
employees of Holdings, LHS, Nurses, PDN or MIV immediately prior to the date of

Notwithstanding anything in this Section 1.6 to the contrary, during the period
                                 -----------

     1.7   Replacement Financing.  Each of Holdings, LHS, Nurses, PDN and MIV
           ---------------------                                             
hereby agrees to execute, deliver and perform on behalf of any successor or
replacement lender to the Senior Lender, a subordination agreement on terms
substantially similar to the terms of the Subordination Agreement.

     1.8   Use of Names.  From and after the date of the LHS/Holdings Closing,
           ------------                                                       
the Selling Parties shall not conduct business: (i) in any location under the
name "Liberty Health Services" or "Nurses Today" or any variation thereof or

Acquisition Agreements (or in any schedule or certificate delivered thereunder)
shall survive the consummation of the transactions contemplated by the
Acquisition Agreements, without regard to any investigation made by any of the
parties hereto, and shall expire on June 30, 1998; provided, however, that the
                                                   --------  -------          
representations and warranties (and all claims and causes of action with respect

4.2 and 4.3 of the Acquisition Agreements shall survive the date of the PDN/MIV

termination of the representations and warranties provided herein shall not
affect the rights of a party seeking indemnification under this Agreement,
provided that such party shall have given written notice to the other party,
prior to the expiration of the applicable survival period provided above, of:
(a) a claim for indemnification or (b) a contingent claim for indemnification
(provided that the party seeking indemnification for such contingent claim has

                                       5
<PAGE>
 
or demand for indemnification will be made and sets forth the estimated amount

the Purchasing Parties (their respective affiliates, and their respective
directors, officers, stockholders, representatives and employees), from and
against all losses, Taxes, liabilities, damages, lawsuits, deficiencies, claims,
demands, costs or expenses, including interest, penalties, and reasonable
attorneys', accountants' and other professionals' fees and disbursements
("Losses"), based upon, incurred in connection with, arising out of or otherwise

or occupied by PDN or MIV, or (d) any liability or obligation of the Selling
Parties that is not an Assumed Liability.

    3.2  Obligation to Indemnify by the Purchasing Parties.  Subject to the
         -------------------------------------------------                 
terms of Section 2, the Purchasing Parties agree to indemnify, defend and hold
         ---------                                                            
harmless the Selling Parties (their affiliates, and their respective directors,
officers, stockholders, representatives and employees) from and against all
Losses based upon, incurred in connection with, arising out of or otherwise in
respect of (a) any inaccuracy in or any breach of any representation or warranty
of the Purchasing Parties contained in the Acquisition Agreements or in any
document delivered pursuant to the Acquisition Agreements, (b) any breach of any
covenant or agreement of the Purchasing Parties contained in the Acquisition
Agreements, this Agreement or in any document or instrument contemplated
hereunder or thereunder, (c) any liability or obligation arising on and after
the date of the LHS/Holdings Closing with respect to any Assumed Liability under
the LHS/Holdings Acquisition Agreement or the date of the PDN/MIV Closing with
respect to any Assumed Liability under the PDN/MIV Acquisition Agreement, or (d)
any liability or obligation resulting from any Action described in Section 7.4
of the Acquisition Agreements for which the Purchasing Parties have agreed in a
separate writing to indemnify the Selling Parties.

    3.3  Losses.  The term "Losses" as used herein (a) is not limited to
         ------                                                         
matters asserted by third parties against the Selling Parties or the Purchasing
Parties, but includes Losses incurred or sustained by the Selling Parties or the
Purchasing Parties in the absence of third-party claims, and (b) includes Losses
incurred through and after the date of the claim for indemnification (including
any Losses suffered after the end of any applicable survival period), provided
that in the case of a claim for Losses incurred because of the breach of a
representation or warranty hereunder, such claim is made within the applicable
survival period under Section 2.  Payments by the Purchasing Parties of amounts
                      ---------                                                
for which the Purchasing Parties are indemnified hereunder, and payments by the
Selling Parties of amounts for which the Selling Parties are indemnified
hereunder, shall not be 

                                       6
<PAGE>
 
condition precedent to recovery. The indemnification rights contained in
Section 3 shall not limit any other rights, including rights of contribution
- ---------      
with respect to environmental liabilities, that either party may have under
statute or common law.

     3.4   Procedures for Claims Between the Parties.  If a claim (a "Claim") is
           -----------------------------------------                            
to be made by the party claiming indemnification (the "Claimant") against the
other party (the "Indemnifying Party"), the Claimant shall give written notice
(a "Claim Notice") to the Indemnifying Party as soon as practicable after the
Claimant becomes aware of the facts, condition or event that may give rise to
Losses for which indemnification may be sought under this Section 3.  Following
                                                          ---------            
receipt of the Claim Notice from the Claimant, the Indemnifying Party shall have
thirty (30) calendar days to make such investigation of the Claim as the
Indemnifying Party deems necessary or desirable; provided, however, that if
                                                 --------  -------         
Claimant reasonably determines that it will be materially prejudiced by
affording the Indemnifying Party such period of time for investigation, the
Indemnifying Party and the Claimant shall agree promptly on the appropriate
period of time for such investigation.  For the purposes of such investigation,
the Claimant agrees to make available to the Indemnifying Party and/or its
authorized representative(s) the information relied upon by the Claimant to
substantiate the Claim. If the Claimant and the Indemnifying Party agree at or
prior to the expiration of said thirty (30) day period (or any mutually agreed
upon period or extension thereof) to the validity and amount of such Claim, the
Indemnifying Party shall pay promptly to the Claimant the full amount of such
Claim.  If the Claimant and the Indemnifying Party do not agree within said
period (or any mutually agreed upon period or extension thereof), the Claimant
may seek appropriate legal remedy.

     3.5  Defense of Third-Party Actions.  If any lawsuit or enforcement action
          ------------------------------                                       
(a "Third Party Action") is filed against a Claimant entitled to the benefit of
indemnity hereunder, written notice thereof (the "Third-Party Action Notice")
shall be given by Claimant to the Indemnifying Party as promptly as practicable
(and in any event within fifteen (15) calendar days after the service of the
citation or summons or other manner of process).  The failure of any Claimant to
give notice timely hereunder shall not affect rights to indemnification
hereunder, except to the extent that the Indemnifying Party demonstrates actual
damage caused by such failure.  After such notice, if the Indemnifying Party
shall acknowledge in writing to the Claimant that the Indemnifying Party shall
be obligated under the terms of its indemnity hereunder in connection with such
Third-Party Action, then the Indemnifying Party shall be entitled, if it so
elects, (i) to take control of the defense and investigation of such Third-Party
Action, (ii) to employ and engage attorneys reasonably satisfactory to the
Claimant to handle and defend the same, at the Indemnifying Party's cost, risk
and expense, and (iii) to compromise or settle such Third-Party Action, which
compromise or settlement shall be made only with the written consent of the
Claimant, such consent not to be unreasonably withheld.  If the Indemnifying
Party fails to assume the defense of such Third-Party Action within fifteen (15)
calendar days after receipt of the Third-Party Action Notice, the Claimant will
(upon delivering notice to such effect to the Indemnifying Party) have the right
to undertake, at the Indemnifying Party's cost and expense, the defense,
compromise or settlement of such Third-Party Action on behalf of and for the
account and risk of the Indemnifying Party; provided, however, that such Third-
                                            --------  -------                 
Party Action shall not be compromised or settled without the written consent of
the Indemnifying Party, which consent shall not be unreasonably withheld,
conditioned or delayed.  In the event the Claimant assumes the defense of the
Third-Party Action, the Claimant will keep the Indemnifying Party reasonably
informed of the progress of any such defense, compromise or settlement.  The

                                       7
<PAGE>
 
Indemnifying Party shall be liable for any settlement of any Third-Party Action
effected pursuant to and in accordance with this Section 3 and for any final
                                                 --------- 
judgment (subject to any right of appeal), and the Indemnifying Party agrees to
indemnify and hold harmless Claimant from and against any Losses by reason of
such settlement or judgment.

     3.6  Bulk Sales.  It may not be practicable to comply or attempt to comply
          ----------                                                           
with the procedures of the "Bulk Sales Act," if applicable, or similar law of
any or all of the states in which the Purchased Assets are situated or of any
other state that may be asserted to be applicable to the transactions
contemplated hereby.  Accordingly, to induce the Purchasing Parties to waive any
requirements for compliance with any or all of such laws, the Selling Parties
hereby agree that the indemnity provisions of this Section 3 hereof shall apply
                                                   ---------                   
to any Losses of the Purchasing Parties arising out of or resulting from the
failure of the Selling Parties or the Purchasing Parties to comply with any such
laws.

     3.7  Interest on Unpaid Obligations.  If all or part of any indemnification
          ------------------------------                                        
obligation under this Agreement is not paid when due, the Indemnifying Party
shall pay the Claimant interest on the unpaid amount of such obligation for each
day from the date the amount became due until it is paid in full, interest at
the rate of 200 basis points in excess of the prime rate in effect from time to
time at CoreStates Bank, N.A., Philadelphia, Pennsylvania, or any successor
thereto.

     3.8  Reduction for Insurance.  The amount which an Indemnifying Party is
          -----------------------                                            
required to pay to, for or on behalf of the Claimant pursuant to this Section 3
                                                                      ---------
shall be reduced (including, without limitation, retroactively) by eighty
percent (80%) of any insurance proceeds actually recovered by or on behalf of
such Claimant in reduction of the related indemnifiable loss (the "Indemnifiable
Loss"). Amounts required to be paid, as so reduced, are hereafter called an
"Indemnity Payment".  If a Claimant shall have received or shall have had paid
on its behalf an Indemnity Payment in respect of an Indemnifiable Loss and shall
subsequently receive insurance proceeds in respect of such Indemnifiable Loss,
then such Claimant shall pay to such Indemnifying Party a sum equal to the
amount of eighty percent (80%) of such insurance proceeds up to an amount equal
to the Indemnity Payment).
 
4.   Breaches and Defaults; Termination; Remedies.
     -------------------------------------------- 

     4.1  Breaches and Defaults; Opportunity to Cure.  Prior to the exercise by
          ------------------------------------------                           
a party of any termination rights afforded under this Agreement, if either party
(the "Non-Breaching Party") believes the other (the "Breaching Party") to be in
breach of an Acquisition Agreement or hereunder, the Non-Breaching Party shall
provide the Breaching Party with written notice specifying in reasonable detail
the nature of such breach, whereupon the Breaching Party shall have fifteen (15)
calendar days from the receipt of such notice to cure such breach.  If a breach
has in fact occurred but is not cured within such time period, then the
Breaching Party shall be in default hereunder and the Non-Breaching Party shall
be entitled to terminate the Acquisition Agreements and this Agreement (as
provided in Section 4.2).  This right of termination shall be in addition to,
            -----------                                                      
and not in lieu of, any legal or equitable remedies available to the Non-
Breaching Party.

     4.2  Termination.  This Agreement and the Acquisition Agreements may be
          -----------                                                       
terminated at any time prior to the LHS/Holdings Closing as follows:

          (a) by mutual written agreement of the parties hereto;

          (b) by the Purchasing Parties, provided the Purchasing Parties are not
then in breach of the Acquisition Agreements or this Agreement, at the election
of the Purchasing Parties (pursuant to a written notice to the Selling Parties),
(i) if any one or more of the conditions to the Purchasing Parties' obligations
to consummate the LHS/Holdings Closing under the LHS/Holdings Acquisition
Agreement has not been fulfilled in any material respect as of the date of the
LHS/Holdings Closing, (ii) subject to Section 4.1, if the Selling Parties have
breached in any material respect any representation, warranty, covenant or
agreement contained in the Acquisition Agreements or in any other agreement or
document delivered pursuant to the Acquisition Agreements, or (iii) if the
LHS/Holdings Closing shall not have taken place by January 15, 1997 (the
"Outside Date") (unless any of the foregoing events shall have resulted
primarily from the Purchasing Parties' breach of any representation, warranty,
covenant or agreement contained in this Acquisition Agreements or this
Agreement); and

          (c) by the Selling Parties, provided the Selling Parties are not then
in breach of the Acquisition Agreements or this Agreement, at the election of
the Selling Parties (pursuant to a written notice to the Purchasing Parties),
(i) if any one or more of the conditions to the Selling Parties' obligations to
consummate the LHS/Holdings Closing has not been fulfilled in any material
respect as of the date of the LHS/Holdings Closing, (ii) subject to Section 4.1,
                                                                    ----------- 
if the Purchasing Parties have breached in any material respect any
representation, warranty, covenant or agreement contained in the Acquisition
Agreements or this Agreement or in any other agreement or document delivered
pursuant to the Acquisition Agreements, or (iii) if the LHS/Holdings Closing
shall not have taken place by the Outside Date (unless any of the foregoing
events shall have resulted primarily from the Selling Parties' breach of any
representation, warranty, covenant or agreement contained in this Agreement).

Notwithstanding any provision that may be to the contrary in this Agreement or
in the Acquisition Agreements, the parties shall have no right to terminate this
Agreement and the Acquisition Agreements after the LHS/Holdings Closing occurs.

     4.3  Effect of Termination.  In the event of any termination of the
          ---------------------                                         
Acquisition Agreements and this Agreement, all obligations of the parties hereto
thereunder and hereunder shall terminate as of such date of termination and the
Acquisition Agreements and this Agreement shall thereafter become void and be of
no further force and effect, and upon such termination no party hereto shall be
liable to the other party, except for Losses resulting from such termination and
from breaches of the Acquisition Agreement and this Agreement prior to such
termination; provided, however, that (a) the obligations contained in Sections
             --------  -------                                        --------
1.5, 3 and 5.2 shall survive any termination hereof, and (b) the foregoing
- --------------                                                            
provisions shall not limit or restrict the availability of specific performance
(as provided in Section 4.4) or other injunctive relief as to the obligations
                -----------                                                  
referred to in clause (a) to the extent that specific performance or such other
relief would otherwise be available to a party hereunder.

Purchased Assets under the Acquisition Agreements and the Business are unique
assets that cannot be readily obtained on the open market and that the
Purchasing Parties will be irreparably injured if the Acquisition Agreements are
not specifically enforced.  Therefore, notwithstanding anything to the contrary
contained in the Acquisition Agreements, this Agreement or otherwise, the
Purchasing Parties shall have the right (but not the obligation) to enforce
specifically the Selling Parties's performance under this Agreement (including
those obligations contained in Sections 1.1, 1.5 and 1.6) in lieu of the
                               --------------------------               
termination of this Agreement and the Acquisition Agreements, and each of the
Selling Parties waives the defense in any such suit that the Purchasing Parties
have an adequate remedy at law and will interpose no opposition, legal or
otherwise, as to the propriety of specific performance as a remedy. The remedies
described in this Section 4.4 shall be in addition to, and not in lieu of, any
                  -----------                                                 
other remedies that the Purchasing Parties may elect to pursue.

such court does not have personal jurisdiction over such party, and (d) consents

parties to this Agreement shall bear their respective expenses incurred in
connection with the preparation, negotiation, execution and performance of the
Acquisition Agreements and this Agreement and the transactions contemplated

the reasonable out-of-pocket costs and expenses (including the reasonable fees
of attorneys and accountants) incurred by them in connection with the
Acquisition Agreements and this Agreement.

     5.3  Further Assurances.  Each of the parties shall execute such agreements
          ------------------                                                    
and documents and take such further actions as may be reasonably required or
desirable to carry out the provisions hereof and the transactions contemplated
hereby.  Each such party shall use its reasonable best efforts to fulfill or
obtain the fulfillment of the conditions to the LHS/Holdings Closing and the
PDN/MIV Closing, including the execution and delivery of any other agreement or
document, the execution and delivery of which are conditions precedent to the

compensation by any broker, finder, agent or similar intermediary claiming to
have been employed by or on behalf of such party, and to bear the cost of legal

          ------------                                                        
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.  If any court determines that any covenant, or any part of
any covenant is invalid or unenforceable, such covenant shall be enforced to the
extent permitted by such court, and all other covenants shall not thereby be
affected and shall be given full effect, without regard to the invalid portions.

     5.6  Notices.  Any notice or other communication required or permitted
          -------
