                    ----------------------------------------------------
Liabilities.  The Seller represents to Buyer that the State of Louisiana has no

attorney's fees and costs in defending such claims. The Seller represents that
there are no trade liabilities of any nature (accrued, absolute, contingent or
otherwise), liens, encumbrances, or security interests on any of the Assets.
Notwithstanding anything contained in this Agreement to the contrary, the Buyer
expressly states that it is not assuming any existing liabilities of any kind in
connection with its purchase of the Assets.

     3.   Existing Obligations.  The Seller represents and warrants that, to the
          --------------------                                              
best of its knowledge and belief, all of the debts, liabilities and obligations
of Seller are listed on the Schedule of Liabilities attached hereto as Exhibit
"I", and such Schedule is complete and accurately reflects all of Seller's
"Existing Obligations" (as hereinafter defined) as of the Closing Date. The term
"Existing Obligations" shall mean and refer to all of the Seller's debts,
liabilities and obligations of any nature (whether absolute, accrued,
contingent, or otherwise) on the Closing Date, including but not limited to any
and all accounts payable, notes payable, trade payables, lease obligations,
indebtedness for borrowed money, accrued interest, contractual obligations, etc.
The Seller acknowledges that the purchase price for the Assets is based on the
accuracy of Seller's representations and warranties contained in this Agreement,
including but not limited to the Seller's representations and warranties
contained in this paragraph 3.

     4.   Right of Offset Against the RoTech Stock.  In the event that: (i) the
          ----------------------------------------                         
Buyer is required to pay for any debts or liabilities of Seller ("Liabilities
Deficiencies") (for the purposes of this subparagraph 4.(i), whether Buyer is
"required" to pay shall be determined by Buyer in the exercise of its reasonable
discretion based on all the facts of which Buyer is aware, e.g., whether legal
action to force payment has commenced, etc.), or (ii) the aggregate value of the
Corporation's collectible accounts receivable as of October 31, 1995, are
determined to be less than $180,140, as determined by actual cash
collections of such receivables during the twelve (12) month period immediately
following the Effective Date (the "Asset Value Deficiency"), or (iii) the
Corporation has, since October 1, 1995, except as disclosed on an exhibit
hereto, made expenditures or incurred obligations or liabilities, except in the
ordinary course of business; discharged or satisfied any liens or encumbrances,
except in the ordinary course of business; declared or made any shareholder
payment or distribution or purchased or redeemed any of its common capital stock
or agreed to do so; mortgaged, pledged or subjected to lien or encumbrance any
of the Assets; sold or transferred any of the Assets; suffered any damage or
loss (whether or not covered by insurance) materially affecting its properties;
waived any rights of substantial value; or entered into any transaction other
than in the ordinary course of business (the "Subsequent Event Deficiency"), or
(iv) the Buyer is required to pay any debts, liabilities or obligations of any
nature (whether absolute, accrued, contingent, or otherwise), other than those
subject to subparagraphs (i) through (iii) of this paragraph 4 (the
"Obligations"), that become known, are uncovered or arise after the Effective
Date, which Obligations pertain to any actions, omissions, debts, liabilities or
obligations of the Corporation or any of its shareholders, created or arising on
or before the Effective Date (said Obligations

                                       3
<PAGE>
 
hereinafter referred to as the "Contingent Liability"); then, and in any of such
events, Buyer shall have the right, for a period of twenty-four (24) months from
the Effective Date, to make offset against the RoTech Stock, in accordance with
the terms and conditions of the Pledge Agreement and Escrow Agreement, in
amounts from time to time equal to any Liabilities Deficiency, Asset Value
Deficiency, Subsequent Event Deficiency or Contingent Liability which becomes
known, is uncovered or arises during the twenty-four (24) month period after the
Effective Date (subject, however, in the case of a "Dispute", to the provisions
of paragraph 18 hereof applicable to a "Dispute") and Seller agrees to pay said
amounts to Buyer immediately upon written request from Buyer to Seller. During
the twenty-four (24) month period following the Effective Date, in the event
Buyer makes written request to Seller hereunder for Seller to pay any
Liabilities Deficiency, Asset Value Deficiency, Subsequent Event Deficiency or
Contingent Liability, and Seller fails to make the requested payment within ten
(10) days from the date of such written request (said ten (10) day period
hereinafter referred to as the "Notice Period"), Buyer shall have the right to
make offset against the RoTech Stock, in accordance with the terms and
conditions of the Pledge Agreement and Escrow Agreement, in amounts from time to
time equal to the amount of any Liabilities Deficiency, Asset Value Deficiency,
Subsequent Event Deficiency or Contingent Liability which becomes known, is
uncovered or arises during the twenty-four (24) month period following the
Effective Date (subject, however, in the case of a "Dispute", to the provisions
of paragraph 18 hereof applicable to a "Dispute"), and the Corporation agrees to
allow Buyer to make offset against the RoTech Stock as herein provided. In the
event an offset against the RoTech Stock is to occur, an offset against one
share of RoTech Stock shall have the effect of reducing any amounts owed Buyer
by $22.75. Buyer's right of offset against the RoTech Stock shall terminate on
that date which is twenty-four (24) months from the Effective Date (the "Release
Date"), provided, however, that notwithstanding anything contained in this
Agreement or in the Pledge Agreement or Escrow Agreement to the contrary, the
right of offset shall extend past the Release Date in the event a claim is in
dispute at the time of the Release Date and, in such instance, the right of
offset shall not terminate until after the settlement of such claim or claims.
In the event the right of offset is extended past the Release Date because a
claim is in dispute, RoTech Stock having a value equal to twice the amount of
the claim asserted by Buyer (using $22.75 per share in such calculation) shall
continue to be held in escrow past the Release Date until such claim is
resolved, with the remaining shares of RoTech Stock released to Seller within
fifteen (15) days after the Release Date. The Buyer shall be entitled to
reimbursement from Seller of the amount of any reasonable legal fees and
expenses (including court costs and the costs of appeal) incurred by Buyer to
enforce the collection of amounts owed Buyer by Seller hereunder.
Notwithstanding anything contained in this paragraph 4 to the contrary, in the
case of a "Dispute" (as defined in paragraph 18 hereof), the provisions of
paragraph 18 hereof applicable to a "Dispute" shall govern, and no offset
against the RoTech Stock shall occur until the applicable "Dispute" is resolved
in accordance with the provisions of paragraph 18 hereof.

     5.   Characteristics of RoTech Stock.
          ------------------------------- 

               (a)  Investment.  The RoTech Stock which the Seller is acquiring
                    ----------                                                 
hereunder is being acquired for Seller's own account, not as a nominee or agent,
and not with a view to the sale or distribution of any part thereof for the
purposes of the Securities Act of 1933, as amended (the "Securities Act").

                                       4
<PAGE>
 
               (b)  Securities Not Registered.  The Seller understands that the
                    -------------------------                                  
RoTech Stock has not been registered under the Securities Act on the ground that
the issuance of such securities hereunder is exempt from registration under the
Securities Act and that Buyer's reliance on such exemption is predicated on
Seller's representations set forth in this paragraph 5.

               (c)  Rule 144.  The Seller acknowledges that the RoTech Stock
                    --------                                                  
must be held indefinitely unless subsequently registered under the Securities
Act or an exemption from such registration is available. Seller is aware of the
provisions of Rule 144 promulgated under the Securities Act which permit limited
resale of securities purchased in a private placement subject to the
satisfaction of certain conditions. Rule 144 currently requires, among other
things, that current information on the issuer be available to the public and
that the shareholder intending to sell under the Rule hold the shares for at
least two (2) years. In the event any of the RoTech Stock held by Seller becomes
eligible for sale pursuant to Rule 144, and an opinion of Buyer's counsel is
necessary to effectuate the transfer of RoTech Stock thereunder, Seller or any
subsequent holder of the RoTech Stock shall bear the costs of obtaining such
opinion of counsel, up to $275.00 for each opinion of counsel issued in
connection with transfers under Rule 144. Buyer shall process any requests for
transfer of RoTech Stock pursuant to Rule 144 in an efficient and prompt manner.

               (d)  Access to Data.  Seller has received and reviewed
                    --------------                                              
information about RoTech Medical Corporation ("RoTech"), including but not
limited to all of items listed on the Schedule of Securities Filings attached
hereto as Exhibit "V", and has had an opportunity to ask questions of, and
receive answers from, Buyer and RoTech concerning RoTech's business, management,
legal and financial affairs and to obtain additional information (to the extent
Buyer possesses such information or could acquire it without unreasonable effort
or expense) necessary to verify the accuracy of any information furnished.
Seller also had the opportunity to inspect RoTech's facilities. Seller
understands that such discussions, as well as any written information issued by
RoTech, were intended to describe the aspects of RoTech's business and prospects
which it believes to be material, but were not necessarily a thorough or
exhaustive description.

               (e)  Risks.  Seller, by reason of its business and financial
                    -----                                                  
experience, has the capacity to protect its own interests in connection with the
transactions contemplated by this Agreement and has the ability to bear the
economic risk of its investment.

               (f)  Restrictive Legends.  Each certificate representing RoTech
                    -------------------                                       
Stock, including any securities issued as a dividend or other distribution with
respect to, in exchange for, or in replacement of such RoTech Stock shall be
stamped or otherwise imprinted with the following legend as well as any other
legends required by applicable state securities laws:

               The securities represented by this stock
               certificate or warrant have been acquired
               pursuant to an investment representation on
               the part of the purchaser thereof and shall
               not be sold, pledged, hypothecated, donated,
               or otherwise transferred, whether or not for
               consideration, by the purchaser except upon
               the issuance to the 

                                       5

               company of a favorable opinion of its counsel
               and/or the submission to the company of such
               other evidence as may be satisfactory to
               counsel to the company, in either case to the
               effect that any such transfer shall not be in
               violation of the Securities Act of 1933, as
               amended, and applicable state securities
               laws.

               (g)  No Registration Rights.  Seller acknowledges that it
                    ----------------------                                    
possesses no rights whatsoever to have any of the RoTech Stock registered.

     6.   Contingent Reduction of Shares of RoTech Stock; Repayment of Cash
          -----------------------------------------------------------------
Consideration; Put Option.
- ------------------------- 

          (a)  Contingent Reduction of Shares of RoTech Stock; Repayment of Cash
               -----------------------------------------------------------------
Consideration.
- ------------- 

                      (1)  Terms of Reduction.  In the event the "First Two
                           ------------------                                  
Year's Average Operating Profits" of the "Purchased Entity" is less than FIVE
HUNDRED THOUSAND DOLLARS ($500,000.00) (the "Threshold Amount"), the number of
shares of RoTech Stock required to be delivered by Buyer to Seller at the end of
the Escrow Period shall be reduced by .2198 shares o f RoTech Stock for every
ONE DOLLAR ($1.00) of the First Two Year's Average Operating Profits during the
Measurement Period below the Threshold Amount, rounded to the nearest full
share, with Buyer retaining complete title to and possession of such shares as
if Buyer were at all times the sole owner of such shares. For example, in the
event the First Two Year's Average Operating Profits of the Purchased Entity
during the Measurement Period is FOUR HUNDRED THOUSAND DOLLARS ($400,000.00),
the difference from the Threshold Amount of ONE HUNDRED THOUSAND DOLLARS
($100,000.00) would result in a reduction hereunder of 21,980 shares of RoTech
Stock ($100,000.00 x .2198), with all of such shares being returned to Buyer by
the Escrow Agent upon final determination of the First Two Year's Average
Operating Profits and with the balance of 13,185 shares of RoTech Stock (less
any offsets pursuant to paragraph 4 hereof) delivered to Seller at the end of
the Escrow Period. In the event the First Two Year's Average Operating Profits
of the Purchased Entity during the Measurement Period is less than THREE HUNDRED
FORTY THOUSAND DOLLARS ($340,000.00) (the "Cash Repayment Threshold Amount"),
resulting in a reduction of all shares of RoTech Stock, the Seller shall pay to
Buyer, immediately upon final determination of the First Two Year's Average
Operating Profits, an amount equal to FIVE DOLLARS ($5.00) for every ONE DOLLAR
($1.00) of the First Two Year's Average Operating Profits during the Measurement
Period below the Cash Repayment Threshold Amount (the "Cash Repayment Amount"),
rounded to the nearest dollar, up to a maximum Cash Repayment Amount of FOUR
HUNDRED FIFTY THOUSAND DOLLARS ($450,000.00). For example, in the event the
First Two Year's Average Operating Profits of the Purchased Entity during the
Measurement Period is THREE HUNDRED THOUSAND DOLLARS ($300,000.00), the
difference from the Cash Repayment Threshold Amount of FORTY THOUSAND DOLLARS
($40,000.00) would result in Seller being obligated to pay Buyer the sum of TWO
HUNDRED THOUSAND DOLLARS ($200,000.00) ($40,000.00 x $5.00). In the event that
the First Two Year's Average Operating Profits of the Purchased Entity are less
than the Threshold Amount and/or Cash Repayment Threshold Amount, the parties
agree that the sole consequence under this Agreement shall be the reduction in
the number of shares of RoTech Stock required to be delivered by Buyer

                                       6

to Seller at the end of the Escrow Period and the payment by Seller to Buyer of
the Cash Repayment Amount as determined above. Buyer shall not effect any
reorganization, recapitalization, splitup, splitoff, consolidation, merger, sale
of all or substantially all of its assets or change in effective control of
Buyer unless prior to or simultaneously with the consummation thereof, the
successor corporation (if other than the Buyer) resulting from such
reorganization, recapitalization, splitup, splitoff, consolidation or merger, or
the corporation purchasing such assets or the persons assuming control of Buyer
shall, by written instrument, preserve the terms of this subparagraph. The
acquisition by an unaffiliated third party of 50% or more of Buyer's issued and
outstanding common stock shall be deemed a change of effective control of Buyer.

                      (2)  Certain Definitions.  The term "First Two Year's
                           -------------------                                
Average Operating Profits" shall have the definition set forth on Exhibit "J"
attached hereto. The term "Purchased Entity" shall mean that division of the
Buyer which represents the Business purchased from Seller hereunder. The
Measurement Period shall mean that period commencing November 1, 1995 and ending
October 31, 1997. During the Measurement Period, the Buyer shall maintain
separate accounting records for the Purchased Entity to track the First Two
Year's Average Operating Profits during the Measurement Period. The term
"Delivered RoTech Shares" shall mean the total number of shares of RoTech Stock
actually delivered to Seller by Buyer by the end of the Escrow Period,
reflecting all reductions pursuant to paragraph 6.(a)(1) hereof and all offsets
pursuant to paragraph 4 hereof. The Delivered RoTech Shares shall be issued with
certificates titled in the name of the Seller's shareholders and having the
following legends printed thereon: the restrictive legend required by paragraph
5.(f) hereof.

                      (3)  Inspection by Seller.  Seller may, at its expense,
                           --------------------                               
from time-to-time during the Measurement Period, review or cause its accountants
to review all books, records, work papers and other accounting records of the
Purchased Entity which pertain specifically to the calculation of the First Two
Year's Average Operating Profits; provided, however, that this right to review
may only be exercised upon reasonable written notice from Seller to Buyer and
then only at reasonable times and dates and with a frequency not more often than
twice in any twelve (12) month period. Any right to review shall immediately
cease if Buyer, in the exercise of its reasonable discretion, determines that
such review is disruptive to the business operations of the Buyer.

     Buyer shall provide to Seller no later than thirty (30) days after the end
of the Measurement Period a statement (the "Statement") showing in reasonable
detail Buyer's calculation of the First Two Year's Average Operating Profits and
the number of shares of RoTech Stock, if any, that Buyer intends to deduct from
the escrow account pursuant to paragraph 6.(a)(1) above.

     Seller may, at its expense, review or cause its accountant to review the
Statement, for which purpose Seller or its accountants shall be given access to
all books, records, work papers and other materials and information relevant to
the calculations set forth in the Statement at such times and dates as are
mutually convenient for Buyer and Seller.

     Seller shall, within fifteen (15) days after receipt of the Statement,
notify Buyer in writing either that (i) it agrees with the amount set forth in
the Statement or (ii) it disagrees with one or more 

                                       7
<PAGE>
 
items in the Statement. Any such notice shall identify the disputed item or
items and shall describe in reasonable detail the basis for the disagreement. If
Seller fails to give any notice in writing to Buyer within fifteen (15) days of
receipt of the Statement, Seller shall be conclusively deemed to agree with the
amounts set forth therein and waive its right to dispute thereafter the amounts
set forth in the Statement unless fraud or bad faith is involved in the
calculation of such amounts.

     If Seller delivers a notice disagreeing with one or more items in the
Statement (which notice shall specify Seller's proposed calculation of the First
Two Year's Operating Profits), Seller and Buyer shall use all reasonable efforts
to resolve the disputed items in such notice.  If, within fifteen (15) days
after receipt by Buyer of such notice, Seller and Buyer are unable to resolve
all of the disputed items specified in such notice, such remaining disputed
items shall be resolved by a firm of independent accountants jointly selected by
Seller and Buyer (or in the absence of agreement on the firm so to be selected,
by Coopers & Lybrand) and the determinations by such firm shall be final and
binding on Seller and Buyer.  All fees and expenses of such firm of independent
accountants shall be borne by Seller and Buyer in inverse proportion to the
amounts of their respective awards with respect to the disputed items resolved
by the firm of independent accountants.  For example, in the event Buyer's
calculation results in a reduction of 10,000 shares of RoTech Stock, and
Seller's calculation results in a reduction of 8,000 shares of RoTech Stock, a
finding by such firm of independent accountants that the reduction should be
9,500 shares would result in Buyer bearing 25% of the cost of such firm of
independent accountants (10,000 minus 9,500, divided by 10,000 minus 8,000) and
Seller bearing 75% of the cost of such firm of independent accountants (9,500
minus 8,000, divided by 10,000 minus 8,000).  Within fifteen (15) days after
final determination of the First Two Year's Average Operating Profits (caused
either by Seller's acceptance of the Statement, or, in the case of any dispute,
final resolution by Buyer and Seller or final resolution by such firm of
independent accountants), all required reductions of RoTech Stock shall be made
(if any) and the Delivered RoTech Shares shall be delivered to Seller (if any),
and Seller shall immediately pay Buyer the Cash Repayment Amount if due as a
result of such final determination. In the event the Cash Repayment Amount, if
due, is not paid immediately upon final determination of the First Two Year's
Average Operating Profits, Buyer shall be entitled to receive interest from
Seller on such amount, calculated at the highest rate allowable by law, and in
the event Buyer institutes legal action against Seller to collect the Cash
Repayment Amount, Seller shall reimburse Buyer for the all attorneys' fees and
costs incurred by Buyer as a result of such legal action.




               (b)  Put Option.
                    ---------- 

                      (1)  Amount and Price.  The Seller shall have the right
                           ----------------
(the "Put Option") to require Buyer to repurchase some or all of the Delivered
RoTech Shares received by Seller pursuant to this Agreement (sometimes herein
referred to as the "Option Shares") at a repurchase price of $22.75 per share
(the "Option Price").

                      (2)  Restrictions On Exercise.  This Put Option is not
                           ------------------------                    
assignable, provided, however, that if Seller distributes any of the Option
Shares to its shareholders (which Seller may do by proper corporate action
without the consent of Buyer), Seller may assign this Put Option to its
shareholders to the extent of the Option Shares distributed to its shareholders.
Seller or, after proper assignment, its shareholders may submit Option Shares
for redemption by Buyer at the applicable Option Price during the period
commencing November 1, 1997 and ending October 31, 1998, but only with respect
to Option Shares representing RoTech Stock which has been released from the
escrow arrangement. This Put Option may only be exercised in blocks of 5,000
shares or more.

                      (3)  Term of Option.  All Option Shares submitted pursuant
                           --------------                              
to this Put Option must be delivered to the executive offices of Buyer, at the
address set forth on page 1 hereof (or at such other address as is communicated
by Buyer to Seller in writing). At 5:00 p.m., E.S.T., October 31, 1998, this Put
Option shall expire and shall thereafter have no prospective effect.

                      (4)  Exercise of Put Option and Delivery of Shares.  To
                           ---------------------------------------------
validly exercise this Put Option, Seller or its shareholders, as applicable,
must execute a statement in which Seller or its shareholders, as applicable,
warrants that it or they have full and clear title to the applicable Option
Shares, free of all liens and encumbrances. Such statement must be accompanied
by original stock certificates evidencing not less than the number of Option
Shares for which the option exercise is made. Further, such certificates must be
accompanied by a validly executed stock power, with signature guaranteed by a
member of the New York Stock Exchange (and who is also a member of the Medallion
Group) or a commercial bank who is a member of the Federal Reserve System (and
who is also a member of the Medallion Group).

                      (5)  Settlement.  Settlement for any Option Shares
                           ----------                                           
redeemed pursuant to this Put Option shall occur on that day which is fifteen
(15) business days from the day such Option Shares are submitted to Buyer with
all required documentation. Such payment shall be made without interest.

                      (6)  Changes in Capitalization.  If, while the Put Option
                           -------------------------                  
is outstanding, the outstanding Option Shares have increased, decreased, changed
into, or been exchanged for a different number or kind of shares or securities
of Buyer or any other corporation through reorganization, merger, consolidation,
tender offer, exchange offer, recapitalization, reclassification, stock split,
reverse stock split, stock dividend or similar transaction, appropriate and
proportionate adjustments shall be made by Buyer in the number and/or kind of
shares which are subject to the Put Option and in the Option Price applicable
thereto.

     7.   Effective Date.  The effective date for the transaction contemplated
          --------------                                                      
under this Agreement will be November 1, 1995 (herein sometimes referred to as

both the Seller and Buyer is herein sometimes referred to as the "Closing Date".

conditions, any of which may be waived in writing by Seller.

               (a)  Compliance with Agreement.  All of the terms and conditions

     17.  Corporate Covenant Not to Compete. The Corporation hereby agrees that
          ---------------------------------                                    
for a period of sixty (60) months from November 1, 1995, the Corporation will
not, directly or indirectly, own, manage, operate, join, control or participate
in the ownership, management, operation or control, of or be connected with, in
any manner, any physician practice management business within the city limits of
New Orleans, Louisiana, or within fifty (50) miles of New Orleans, Louisiana.

     The Corporation agrees that the remedy at law for any breach by the
Corporation of the foregoing will be inadequate and that Buyer shall be entitled
to injunctive relief and reimbursement from the Corporation for all costs and
expenses, including attorneys' fees and court costs, incurred by Buyer in
connection with the enforcement of this Covenant Not to Compete.  If any
provisions of this paragraph shall be held invalid, the Corporation agrees that
such provisions shall be severed and the balance thereof shall remain valid and
enforceable.  In the event that a court of competent jurisdiction determines
that the scope of business restricted or the time or geographic limitations
imposed are too broad to be capable of enforcement, the Corporation agrees that
such court may ignore such provisions and instead enforce the provisions as to
such scope, time and geographical area as the court deems proper.  This Covenant
Not to Compete shall be governed by the internal laws of the State of Louisiana,
without reference to applicable principles of conflicts of law, and any action
involving this Covenant Not to Compete shall be brought in the court of
appropriate jurisdiction in Orleans Parish, Louisiana.

               (a)  Indemnification of Seller.  The Seller shall and hereby
                    -------------------------                               
agrees to indemnify and hold harmless at all times, Buyer and its directors,
officers, employees, agents and assigns, as to and against any Damages (as
hereinafter defined) resulting from: (i) any materially inaccurate
representation made by Seller in or under this Agreement; (ii) breach of any
warranties made by Seller in or under this Agreement; (iii) breach or default in
the performance by Seller of any of the covenants to be performed by Seller
hereunder; and (iv) any debts, liabilities or obligations of the Seller
pertaining to the Business, whether accrued, absolute, contingent or otherwise,

               (d)  Remedies.
                    -------- 

                      (1)  Buyer's Remedies.  In the event Buyer makes written
                           ----------------
request to the Seller for the payment of Damages and the Seller fails to make
the requested payment within ten (10) days from the date of such written request
(said ten (10) day period hereinafter referred to as the "Notice Period"), Buyer
shall have the right: (i) if such request is made during the Escrow Period and
RoTech Stock sufficient to pay such Damages in full is held by Buyer in escrow,
to make offset against the RoTech Stock, in accordance with the terms and
conditions of this Agreement and the related Pledge Agreement and Escrow
Agreement; (ii) if such request is made during the Escrow Period and the amount
of RoTech Stock held by Buyer in escrow is insufficient to pay such Damages in
full, to first make offset against any RoTech Stock held in escrow and then to
require Seller to pay Buyer the remaining balance in cash within the ten (10)
day period following the applicable Notice Period (and Seller shall be liable
for such balance and for the payment of such balance in full during such
period); and (iii) if such request is made during the Escrow Period and no
RoTech Stock is being held in escrow by Buyer at the time of such request, or if
such request is made after the Escrow Period, to require the Seller to pay Buyer
the full amount of such Damages in cash within the ten (10) day period following
the applicable Notice Period (and Seller shall be liable for such amount and for
the payment of such amount in full during such period); provided, however, that
in any of the events described in (i) through (iii) of this subparagraph (d),
the Seller shall have the option to provide written notice to Buyer within the
Notice Period that the Seller disputes the validity of the Damages triggering
the right of offset against the RoTech Stock and/or the requirement for payment
by Seller in cash, and in the event Buyer and the Seller cannot reach agreement
on the validity of such Damages by the end of the ten (10) day period following
the Notice Period, the dispute over the validity of such claim or liability (the
"Dispute") shall be settled as set forth in subparagraph (e) of this paragraph
18, with the non-prevailing party bearing the prevailing party's costs of
arbitration in the event any Dispute is resolved by arbitration.

                      (2)  Seller's Remedies.  In the event Seller makes written
                           -----------------                          
request to Buyer for the payment of Damages and Buyer fails to make the
requested payment within ten (10) days from the date of such written request
(said ten (10) day period hereinafter referred to as the "Notice Period"),
Seller shall have the right to require Buyer to pay Seller the full amount of
such Damages in cash within the ten (10) day period following the applicable
Notice Period (and Buyer shall be liable for such amount and for the payment of
such amount in full during such period); provided, however, that Buyer shall
have the option to provide written notice to Seller within the Notice Period
that Buyer disputes the validity of the Damages triggering the requirement for
payment by Buyer in cash, and in the event Seller and Buyer cannot reach
agreement on the validity of such Damages by the end of the ten (10) day period
following the Notice Period, the dispute over the validity of such Damages shall
be settled by arbitration, with the non-prevailing party bearing all of the
prevailing party's costs of arbitration. In the event an arbitration is required
pursuant to this subsection (2) of subparagraph (d), Buyer and Seller will each
select an arbitrator; those two arbitrators will then select a third arbitrator;
and the three arbitrators so chosen will determine the validity of the claim for
Damages. In the event either party fails to appoint an abitrator by the end of
the thirty (30) day period following the Notice Period, the arbitrator appointed
by the other party shall arbitrate the dispute.

               (e)  Settlement of Disputes.
                    ---------------------- 

                      (1)  Disputes Involving Claims by Buyer Against the Seller
                           -----------------------------------------------------
(Not Involving Third Parties). In the event a Dispute arises which Dispute
- ----------------------------     
involves claims by Buyer against the Seller (i.e., not involving any third
parties), Buyer and the Seller shall settle the Dispute by submitting same to
settlement by arbitration. In the event arbitration is required pursuant to this
subsection (1) of subparagraph (e), the Seller shall immediately place cash in
the full amount of the requested Damages into a separate escrow fund at Buyer's
direction pending resolution of the Dispute, and Buyer and the Seller will each
select an arbitrator; those two arbitrators will then select a third arbitrator;
and the three arbitrators so chosen will settle the Dispute (the failure of
Seller to place such amount in escrow shall cause the full amount of Damages to
be immediately due and payable by Seller in full). In the event either party
fails to appoint an abitrator by the end of the thirty (30) day period following
the Notice Period, the arbitrator appointed by the other party shall arbitrate
the dispute. In the event the final settlement of the Dispute is for an amount
less than the amount in escrow, the balance shall be refunded to the Seller; and
in the event the final settlement of the Dispute is for an amount greater than
the amount in escrow, the Seller shall be liable for the excess, which amount
shall be immediately due and payable.

                      (2)  Disputes Involving Claims Made by Third Parties.  In
                           -----------------------------------------------
the event a Dispute arises which Dispute involves claims made by a third party
or parties (the "Third Party Claim"), Buyer shall give written notice to the
Seller as soon as practical after Buyer receives notice of a Third Party Claim.
If any lawsuit or enforcement action is filed against Buyer by a person
asserting a Third Party Claim, written notice shall be given to the Seller as
promptly as is practicable (in any event, within ten (10) days after the service
of citation or summons). After such notice, if the Seller shall acknowledge in
writing to Buyer that the Seller shall be obligated for such Third Party Claim
and if the Seller shall have placed the disputed amount of the Third Party Claim
(which amount shall be the full amount of the Third Party Claim or, in the
exercise of the Buyer's sole discretion, an amount specified by Buyer which is
less than the full amount of the Third Party Claim) in a separate escrow fund at
Buyer's direction pending resolution of the Third Party Claim (the failure of
Seller to place such amount in escrow shall cause the full amount of Damages to
be immediately due and payable by Seller in full), then the Seller shall be
entitled, if Seller so elects, to take control of the defense and investigation
of such lawsuit or action and to employ and engage attorneys of its own choice
to handle and defend the same, at the Seller's cost, risk and expense, provided
that the Seller and its counsel shall proceed with diligence and in good faith
with respect thereto. Buyer shall cooperate in all reasonable respects with the
Seller and their attorneys in the investigation, trial and defense of such
lawsuit or action and any appeal arising therefrom; provided, however, that
Buyer may, at Buyer's expense, participate in the investigation, trial and
defense of such lawsuit or action and any appeal arising therefrom. If the
Seller has acknowledged to Buyer its obligation to Buyer hereunder and has
placed the disputed amount (or such lesser amount specified by Buyer in the
exercise of its sole discretion) of the Third Party Claim in a separate escrow
fund as required hereunder, Buyer shall not settle such lawsuit or enforcement
action without the prior written consent of the Seller and, if the Seller has ot
so acknowledged its obligation or has failed to place the required amount in
escrow, Buyer shall not settle such lawsuit or enforcement action without ten
(10) days prior notice to the Seller. In the event the final settlement of the
Third Party Claim is for an amount less than the 

                                       18
<PAGE>
 
amount in escrow, the balance shall be refunded to the Seller; and in the event
the final settlement of the Third Party Claim is for an amount greater than the
amount in escrow, the Seller shall be liable for the excess, which amount shall
be immediately due and payable.

     19.  Use of Corporate Name.  Seller agrees to take all actions reasonably
          ----------------------                                              
necessary to assist Buyer in obtaining the rights to utilize the corporate name

               --------------                                            
Covenant Not to Compete shall be TWO MILLION FIVE HUNDRED THOUSAND DOLLARS

Seller's account number 4000052229 at First American National Bank against and

pursuant to paragraph 15 hereof, for the twelve (12) month period following the

for a period of twelve (12) months (the "Escrow Period") with the law firm of

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

- -----------                                                                     
bulk sales and transfer laws of the State of Tennessee. Seller agrees to
indemnify Buyer and hold Buyer harmless against all claims made by creditors of
the Seller which relate to the Business, including, but not limited to
reasonable attorney's fees and costs in defending such claims.

                                       2
<PAGE>
 
     The Seller represents that there are no trade liabilities of any nature
(accrued, absolute, contingent or otherwise), liens, encumbrances, or security
interests on any of the Assets. Notwithstanding anything contained in this
Agreement to the contrary, the Buyer expressly states that it is assuming no
existing liabilities of any kind in connection with its purchase of the Assets,
except for those operating leases and debts (not to exceed $202,071.11.) set
forth on the Schedule of Liabilities Assumed attached hereto as Exhibit "F." The
Buyer is also assuming a durable medical equipment agreement by and between
Seller and Sentry Home Health Services, as more specifically described in
Exhibit "I," attached hereto and made a part hereof.

     3.   Existing Obligations. The Seller represents and warrants that, to the 
          --------------------                                       
best of its knowledge and belief all of the Seller's debts, liabilities and
obligations are listed on the Schedule of Liabilities attached hereto as Exhibit
"J" and such schedule accurately reflects all of Seller's "Existing Obligations"
(as hereinafter defined) as of the Closing Date. The term "Existing Obligations"
shall mean and refer to all of the Seller's debts, liabilities and obligations
of any nature (whether absolute, accrued, contingent, or otherwise) on the
Closing Date, including but not limited to any and all accounts payable, notes
payable, trade payables, lease obligations, indebtedness for borrowed money,
accrued interest, contractual obligations, etc. The Seller acknowledges that the
purchase price for the Assets is based on the accuracy of Seller's
representations and warranties contained in this Agreement, including but not
limited to the Seller's representations and warranties contained in this
paragraph 3.

     4.   Right of Offset Against the Escrowed Amount. In the event that:
          -------------------------------------------                    
(i) the Buyer pays for any debts or liabilities of Seller other than those
liabilities in the amounts listed on the Schedule of Liabilities Assumed
attached hereto as Exhibit "F" (the "Liabilities Deficiencies"), or (ii) the
aggregate value of the Corporation's collectible accounts receivable as of
December 31, 1995, are determined to be less than $250,000.00, as determined by
actual cash collections of such receivables during the twelve (12) month period
immediately following the Effective Date (the "Asset Value Deficiency"), or
(iii) the Corporation has, since December 1, 1995, made expenditures or incurred
obligations or liabilities, except in the ordinary course of business;
discharged or satisfied any liens or encumbrances, except in the ordinary course
of business; declared or made any shareholder payment or distribution or
purchased or redeemed any of its common capital stock or agreed to do so;
mortgaged, pledged or subjected to lien or encumbrance any of its assets; sold
or transferred any assets; suffered any damage or loss (whether or not covered
by insurance), materially affecting its properties; waived any rights of
substantial value; or entered into any transaction other than in the ordinary
course of business (the "Subsequent Event Deficiency"), or (iv) any debts,
liabilities or obligations of any nature (whether absolute, accrued, contingent,
or otherwise), other than those subject to subparagraphs (i) through (iii) of
this paragraph 4 (the "Obligations"), become known, are uncovered or arise after
the Effective Date, which Obligations pertain to any actions, omissions, debts,
liabilities or obligations of the Corporation or any of its shareholders,
created or arising on or before the Closing Date (said Obligations hereinafter
referred to as the "Contingent Liability"); then, and in any of such events,
Buyer shall have the right, for a period of twelve (12) months from the
Effective Date, to make offset against the Escrowed Cash, in accordance with the
terms and conditions of the Escrow

                                       3
<PAGE>
 
Agreement, in amounts from time to time equal to any Liabilities Deficiency,
Asset Value Deficiency, Subsequent Event Deficiency or Contingent Liability
which becomes known, is uncovered or arises during the twelve (12) month period
after the Effective Date, and Seller agrees to pay said amounts to Buyer
immediately upon written request from Buyer to Seller. During the twelve (12)
month period following the Effective Date, in the event Buyer makes written
request to Seller hereunder and Seller fails to make the requested payment
within ten (10) days from the date of such written request (said ten (10) day
period hereinafter referred to as the "Notice Period"), Buyer shall have the
right to make offset against the Escrowed Cash, in accordance with the terms and
conditions of the Escrow Agreement, in amounts from time to time equal to the
amount of any Liabilities Deficiency, Asset Value Deficiency, Subsequent Event
Deficiency or Contingent Liability which becomes known, is uncovered or arises
during the twelve (12) month period following the Effective Date, and the
Corporation agrees to allow Buyer to make offset against the Escrowed Cash as
herein provided. In the event an offset against the Escrowed Cash is to occur,
an offset against one dollar ($1.00) of the Escrowed Cash shall have the effect

     NOW, THEREFORE, in consideration of the mutual promises contained herein
and for other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, it is hereby agreed as follows:

     2.   Purchase Price.
          -------------- 

          (a)  Purchase Price.  The purchase price for the Assets and the
               --------------                                            
Covenant Not to Compete shall be TWO MILLION SIX HUNDRED THOUSAND DOLLARS
($2,600,000.00) in cash (the "Cash Consideration"), plus 41,818 shares of the
common stock, par value $.0002, of RoTech Medical Corporation, a Florida
corporation (the "RoTech Stock") (the Cash Consideration and RoTech Stock are
sometimes herein referred to together as the "Purchase Price"), which RoTech
Stock shall be issued with certificates titled in the name of the Seller and
having the following legends printed thereon: the restrictive legend required by
paragraph 5(f) hereof.  The Purchase Price shall be allocated among the Assets
and the Covenant Not to Compete in the manner set forth on the Allocation
Schedule attached hereto as Exhibit "F" and by this reference made a part
hereof, and both parties hereto expressly consent to the allocation stated
therein.

          (b)  Method of Payment.  Cash Consideration in the amount of
               -----------------                                      
$2,600,000.00 (less $65,000.00 payable to Steven Richards & Associates and less
$110,000.00 payable to Timothy Binkley) will be paid to Seller on the Closing
Date, by wired funds to Seller's account number 00039834 at Central Southern 
Bank against and in consideration of the Assets and Covenant Not to Compete.
Seller agrees that each of Steven Richards & Associates and Timothy Binkley have
acted as their representative and broker in connection with the transactions
contemplated by this Agreement. Accordingly, Seller agrees that Buyer shall be
authorized to withhold from its payment of the Cash Consideration the amount of
$65,000.00, payable by Seller to Steven Richards & Associates and to disburse
said amount directly to Steven Richards & Associates, and Seller further agrees
that RoTech shall be authorized to withhold from its payment of the Cash
Consideration the amount of $110,000.00, payable by Seller to Timothy Binkley
and to disburse said amount directly to Timothy Binkley. The RoTech Stock shall
be pledged pursuant to the terms of that certain Stock Pledge and Security
Agreement, in the form attached hereto as Exhibit "G" and by reference made a
part hereof (the "Pledge Agreement"), and shall be placed in escrow for a period
of twenty-four (24) months (the "Escrow Period") with the law firm of
Winderweedle,

                                       2
<PAGE>
 
Haines, Ward & Woodman, P.A. ("WHWW"), to be held by WHWW pursuant to the terms
of that certain Escrow Agreement, in the form attached hereto as Exhibit "H" and
by reference made a part hereof (the "Escrow Agreement").  The Buyer shall cause
the RoTech Stock to be delivered directly to Escrow Agent within thirty (30)
days from the Closing Date. The parties hereto acknowledge that the RoTech Stock
being placed in escrow is subject to reduction pursuant to paragraph 6(a)
hereof.

          (c)  Indemnity Against Creditors Claims; Assumption of Certain
               ---------------------------------------------------------
Liabilities.  The Seller has requested the Buyer to waive the requirements of
- -----------                                                                     
the bulk sales and transfer laws of the State of Georgia. Seller agrees to
indemnify Buyer and hold Buyer harmless against all claims made by creditors of
the Seller which relate to the Business, including, but not limited to
reasonable attorney's fees and costs in defending such claims. The Seller
represents that there are no trade liabilities of any nature that encumber the
Assets (accrued, absolute, contingent or otherwise), nor are there any other
liens, encumbrances, or security interests on any of the Assets. Notwithstanding
anything contained in this Agreement to the contrary, the Buyer expressly states
that it is assuming no existing liabilities of any kind in connection with its
purchase of the Assets, except those certain liabilities set forth on the
Schedule of Liabilities Assumed attached hereto as Exhibit "U," and those
certain leases, contracts and agreements set forth on the Schedule of Leases,
Contracts and Agreements attached hereto as Exhibit "O."

     3.   Existing Obligations.  The Seller represents and warrants that, to the
          --------------------                                       
best of its knowledge and belief all of the Seller's debts, liabilities and
obligations are listed on the Schedule of Liabilities attached hereto as Exhibit
"I" and such schedule accurately reflects all of Seller's "Existing Obligations"
(as hereinafter defined) as of December 31, 1995, except for liabilities
incurred in the ordinary course of business between November 30, 1995, and
December 31, 1995, which will be provided to Buyer as soon as available. The
term "Existing Obligations" shall mean and refer to all of the Seller's debts,
liabilities and obligations of any nature (whether absolute, accrued,
contingent, or otherwise) on the Effective Date, including but not limited to
any and all accounts payable, notes payable, trade payables, lease obligations,
indebtedness for borrowed money, accrued interest, contractual obligations, etc.
The Seller acknowledges that the purchase price for the Assets is based on the
accuracy of Seller's representations and warranties contained in this Agreement,
including but not limited to the Seller's representations and warranties
contained in this paragraph 3.

     4.   Right of Offset Against the RoTech Stock.  Subject to the limitations
          ----------------------------------------                  
of paragraph 17 of this Agreement, in the event that: (i) the Buyer pays for any
debts or liabilities of Seller in excess of those certain liabilities, set forth
on the Schedule of Liabilities Assumed attached hereto as Exhibit "U," and those
certain leases, contracts and agreements set forth on the Schedule of Leases,
Contracts and Agreements attached hereto as Exhibit "O (amount in excess of the
amounts set forth on Exhibits "U" and "O" are herein referred to as the
"Liabilities Deficiency"), or (ii) the aggregate value of the Corporation's
collectible accounts receivable as of November 30, 1995, are determined to be
less than $_______, as determined by actual cash collections of such receivables
during the twelve (12) month period immediately following the Closing Date (the

                                       3
<PAGE>
 
"Asset Value Deficiency"), or (iii) the Corporation has, since November 1, 1995
except as disclosed on an exhibit hereto, made expenditures or incurred
obligations or liabilities, except in the ordinary course of business;
discharged or satisfied any liens or encumbrances except in the ordinary course
of business, declared or made any shareholder payment or distribution except in
the ordinary course of business, or purchased or redeemed any of its common
capital stock or agreed to do so; mortgaged, pledged or subjected to lien or
encumbrance any of its assets except in the ordinary course of business; sold or
transferred any assets; suffered any damage or loss (whether or not covered by
insurance), materially affecting its properties; waived any rights of
substantial value; or entered into any transaction other than in the ordinary
course of business (the "Subsequent Event Deficiency"), or (iv) any debts,
liabilities or obligations of any nature (whether absolute, accrued, contingent,
or otherwise), other than those subject to subparagraphs (i) through (iii) of
this paragraph 4 (the "Obligations"), become known, are uncovered or arise after
the Closing Date, which Obligations pertain to any actions, omissions, debts,
liabilities or obligations of the Corporation or any of its shareholders,
created or arising on or before the Closing Date (said Obligations hereinafter
referred to as the "Contingent Liability");then, and in any of such events,
Buyer shall have the right, for a period of twenty-four (24) months from the
Effective Date, to make offset against the RoTech Stock, in accordance with the
terms and conditions of the Pledge Agreement and Escrow Agreement, in amounts
from time to time equal to any Liabilities Deficiency, Asset Value Deficiency,
Subsequent Event Deficiency or Contingent Liability which becomes known, is
uncovered or arises during the twenty-four (24) month period after the Effective
Date (subject, however, in the case of a "Dispute", to the provisions of
paragraph 17 hereof applicable to a "Dispute") and Seller agrees to pay said
amounts to Buyer immediately upon written request from Buyer to Seller.  During
the twenty-four (24) month period following the Effective Date, in the event
Buyer makes written request to Seller hereunder for Seller to pay any
Liabilities Deficiency, Asset Value Deficiency, Subsequent Event Deficiency or
Contingent Liability, and Seller fails to make the requested payment within ten
(10) days from the date of such written request (said ten (10) day period
hereinafter referred to as the "Notice Period"), Buyer shall have the right to
make offset against the RoTech Stock, in accordance with the terms and
conditions of the Pledge Agreement and Escrow Agreement, in amounts from time to
time equal to the amount of any Liabilities Deficiency, Asset Value Deficiency,
Subsequent Event Deficiency or Contingent Liability which becomes known, is
uncovered or arises during the twenty-four (24) month period following the
Effective Date (subject, however, in the case of a "Dispute", to the provisions
of paragraph 17 hereof applicable to a "Dispute"), and the Corporation agrees to
allow Buyer to make offset against the RoTech Stock as herein provided.  In the
event an offset against the RoTech Stock is to occur, an offset against one
share of RoTech Stock shall have the effect of reducing any amounts owed Buyer
by $27.50.  Buyer's right of offset against the RoTech Stock shall terminate on
that date which is twenty-four (24) months from the Effective Date (the "Release
Date"), provided, however, that notwithstanding anything contained in this
Agreement or in the Pledge Agreement or Escrow Agreement to the contrary, the
right of offset shall extend past the Release Date in the event a claim is in
dispute at the time of the Release Date and, in such instance, the right of
offset shall not terminate until after the settlement of such claim or claims.
In the event the right of offset is extended past the Release Date because a
claim is in dispute, RoTech Stock having a value equal to twice the amount of
the claim asserted by Buyer (using $27.50 per share in such calculation) shall
continue to be held in escrow

                                       4
<PAGE>
 
past the Release Date until such claim is resolved, with the remaining shares of
RoTech Stock released to Seller within fifteen (15) days after the Release Date.
The Buyer shall be entitled to reimbursement from Seller of the amount of any
reasonable legal fees and expenses (including court costs and the costs of
appeal) incurred by Buyer to enforce the collection of amounts owed Buyer by
Seller hereunder.  Notwithstanding anything contained in this paragraph 4 to the
contrary, in the case of a "Dispute" (as defined in paragraph 17 hereof), the
provisions of paragraph 17 hereof applicable to a "Dispute" shall govern, and no
offset against the RoTech Stock shall occur until the applicable "Dispute" is
resolved in accordance with the provisions of paragraph 17 hereof. The offset
provisions of this paragraph 4 shall also be subject to the threshold liability
provisions set forth in subparagraph (f) of paragraph 17 hereof.

     5.   Characteristics of RoTech Stock.
          ------------------------------- 

          (a)  Investment.  The RoTech Stock which the Seller is acquiring
               ----------                                                 
hereunder is being acquired for Seller's own account, not as a nominee or agent,
and not with a view to the sale or distribution of any part thereof for the
purposes of the Securities Act of 1933, as amended (the "Securities Act").

          (b)  Securities Not Registered.  The Seller understands that the
               -------------------------                                  
RoTech Stock has not been registered under the Securities Act on the ground that
the issuance of such securities hereunder is exempt from registration under the
Securities Act and that Buyer's reliance on such exemption is predicated on
Seller's representations set forth in this paragraph 5.

          (c)  Rule 144.  The Seller acknowledges that the RoTech Stock must be
               --------                                                        
held indefinitely unless subsequently registered under the Securities Act or an
exemption from such registration is available.  Seller is aware of the
provisions of Rule 144 promulgated under the Securities Act which permit limited
resale of securities purchased in a private placement subject to the
satisfaction of certain conditions.  Rule 144 requires, among other things, that
current information on the issuer be available to the public and that the
shareholder intending to sell under the Rule hold the shares for at least two
(2) years.  In the event any of the RoTech Stock held by Seller becomes eligible
for sale pursuant to Rule 144, and an opinion of Buyer's counsel is necessary to
effectuate the transfer of RoTech Stock thereunder, Seller or any subsequent
holder of the RoTech Stock shall bear the costs of obtaining such opinion of
counsel, up to $275.00 for each opinion of counsel issued in connection with
transfers under Rule 144.  Buyer shall process any requests for transfer of
RoTech Stock pursuant to Rule 144 in an efficient and prompt manner.

          (d)  Access to Data.  Seller has received and reviewed information
               --------------                                               
about RoTech and has had an opportunity to ask questions of, and receive answers
from, Buyer concerning RoTech's business, management, legal and financial
affairs and to obtain additional information (to the extent Buyer possesses such
information or could acquire it without unreasonable effort or expense)
necessary to verify the accuracy of any information furnished.  Seller also had
the opportunity to inspect RoTech's facilities.  Seller understands that such
discussions, as well as any written information issued by RoTech, were intended
to describe the aspects of RoTech's business

                                       5
<PAGE>
 
and prospects which it believes to be material, but were not necessarily a
thorough or exhaustive description.

          (e)  Risks.  Seller is experienced in evaluating and investing in
               -----                                                       
high risk companies such as Buyer and by reason of its business and financial
experience has the capacity to protect its own interests in connection with the
transactions contemplated by this Agreement and has the ability to bear the
economic risk of its investment.

          (f)  Restrictive Legend.  Each certificate representing RoTech Stock,
               ------------------                                              
including any securities issued as a dividend or other distribution with respect
to, in exchange for, or in replacement of such RoTech Stock shall be stamped or
otherwise imprinted with the following legend as well as any other legends
required by applicable state securities laws:

          The securities represented by this stock
          certificate or warrant have been acquired pursuant
          to an investment representation on the part of the
          purchaser thereof and shall not be sold, pledged,
          hypothecated, donated, or otherwise transferred,
          whether or not for consideration, by the purchaser
          except upon the issuance to the company of a
          favorable opinion of its counsel and/or the
          submission to the company of such other evidence
          as may be satisfactory to counsel to the company,
          in either case to the effect that any such
          transfer shall not be in violation of the
          Securities Act of 1933, as amended, and applicable
          state securities laws.

          (g)  No Registration Rights.  Seller acknowledges that it possesses
               ----------------------                                        
no rights whatsoever to have any of the RoTech Stock registered.

     6.   Contingent Reduction of Shares of RoTech Stock; Put Option.
          ---------------------------------------------------------- 

          (a)  Contingent Reduction of Shares of RoTech Stock.
               ---------------------------------------------- 

               (1)  Terms of Reduction.  In the event the "First Two Year's
                    ------------------                               
Average Operating Profits" of the "Purchased Entity" is less than SEVEN HUNDRED
FIFTY THOUSAND DOLLARS ($750,000.00) (the "Threshold Amount"), the number of
shares of RoTech Stock required to be delivered by Buyer to Seller at the end of
the Escrow Period shall be reduced by .1818 shares of RoTech Stock for every ONE
DOLLAR ($1.00) of the First Two Year's Average Operating Profits during the
Measurement Period below the Threshold Amount, rounded to the nearest full
share, with Buyer retaining complete title to and possession of such shares as
if Buyer were at all times the sole owner of such shares. For example, in the
event the First Two Year's Average Operating Profits of the Purchased Entity
during the Measurement Period is $650,000.00, the difference from the Threshold
Amount of $100,000.00 would result in a reduction hereunder of 18,181 shares of
RoTech Stock ($100,000.00 x .1818), with all of such shares being returned to
Buyer by the Escrow Agent upon final determination of the First

                                       6
<PAGE>
 
Two Year's Average Operating Profits and with the balance of 23,637 shares of
RoTech Stock (less any offsets pursuant to paragraph 4 hereof) delivered to
Seller at the end of the Escrow Period. In the event that the First Two Year's
Average Operating Profits of the Purchased Entity are less than the Threshold
Amount, the parties agree that the sole consequence under this Agreement shall
be the reduction in the number of shares of RoTech Stock required to be
delivered by Buyer to Seller at the end of the Escrow Period.  If said reduction
results in return of all of the RoTech Stock to Buyer, there shall be no other
liability of Seller to Buyer solely for failure to equal or exceed the Threshold
Amount.  Both Buyer and Seller agree, that if at any time during the first two
(2) years following the Effective Date, the Purchased Entity achieves
$1,500,000.00 in Two Years' Average Operating Profits, all escrowed RoTech Stock
shall be released to Seller, subject to any extraordinary event, and any RoTech
Stock released shall remain subject to the restrictions set forth in paragraph 5
above.

delivered to Seller by Buyer by the end of the Escrow Period, reflecting all
reductions pursuant to paragraph 6(a)(1) hereof and all offsets pursuant to
paragraph 4 hereof.  The Delivered RoTech Shares shall be issued with
certificates titled in the name of the Seller and having the following legends
printed thereon: the restrictive legend required by paragraph 5(f) hereof.

               --------------------                                          
Employment Agreement substantially in the form attached hereto as Exhibit "T"
and by this reference made a part hereof.

     15.  Survival of Representations and Warranties.  The representations and
          ------------------------------------------                          
warranties of Seller and Buyer contained and made pursuant to this Agreement
shall survive the execution of this Agreement.

     16.  Corporate Covenant Not to Compete. The Corporation hereby agrees
          ---------------------------------                               
that for a period of sixty (60) months from January 1, 1996, the Corporation
will not, directly or indirectly, own, manage, operate, join, control or
participate in the ownership, management, operation or control, of or be
connected with, in any manner, any home care business within fifty (50) miles of
511 North Cobb Street, Suite 6, Milledgeville, Georgia and/or within fifty (50)
miles of 220 Alcovy Street, Monroe, Georgia.

     The Corporation agrees that the remedy at law for any breach by the
Corporation of the foregoing will be inadequate and that Buyer shall be entitled
to injunctive relief and reimbursement from the Corporation for all costs and
expenses, including attorneys' fees and court costs, incurred by Buyer in
connection with the enforcement of this Covenant Not to Compete.  If any
provisions

                                       13
<PAGE>
 
of this paragraph shall be held invalid, the Corporation agrees that such
provisions shall be severed and the balance thereof shall remain valid and
enforceable.  In the event that a court of competent jurisdiction determines
that the scope of business restricted or the time or geographic limitations
imposed are too broad to be capable of enforcement, the Corporation agrees that
such court may ignore such provisions and instead enforce the provisions as to
such scope, time and geographical area as the court deems proper.  This Covenant
Not to Compete shall be governed by the laws of the State of Georgia and any
action involving this Covenant Not to Compete shall be brought in the court of
appropriate jurisdiction in Baldwin County, Georgia.

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

          (c)  Definition of Damages.  The term "Damages" as used herein, shall
               ---------------------                                           
include any demands, claims, actions, deficiencies, losses, delinquencies,

          (d)  Remedies.
               -------- 

               (1)  Buyer's Remedies.  In the event Buyer makes written request
                    ----------------                                          
to the Seller for the payment of Damages and the Seller fails to make the
requested payment within ten (10) days from the date of such written request
(said ten (10) day period hereinafter referred to as the "Notice Period"), Buyer
shall have the right: (i) if such request is made during the Escrow Period and
RoTech Stock sufficient to pay such Damages in full is held by Buyer in escrow,
to make offset against the RoTech Stock, in accordance with the terms and
conditions of this Agreement and the related Pledge Agreement and Escrow
Agreement; (ii) if such request is made during the Escrow Period and the amount
of RoTech Stock held by Buyer in escrow is insufficient to pay such Damages

                                       14
<PAGE>
 
in full, to first make offset against any RoTech Stock held in escrow and then
to require Seller to pay Buyer the remaining balance in cash within the ten (10)
day period following the applicable Notice Period (and Seller shall be liable
for such balance and for the payment of such balance in full during such
period); and (iii) if such request is made during the Escrow Period and no
RoTech Stock is being held in escrow by Buyer at the time of such request, or if
such request is made after the Escrow Period, to require the Seller to pay Buyer
the full amount of such Damages in cash within the ten (10) day period following
the applicable Notice Period (and Seller shall be liable for such amount and for
the payment of such amount in full during such period); provided, however, that
in any of the events described in (i) through (iii) of this subparagraph (d),
the Seller shall have the option to provide written notice to Buyer within the
Notice Period that the Seller disputes the validity of the Damages triggering
the right of offset against the RoTech Stock and/or the requirement for payment
by Seller in cash, and in the event Buyer and the Seller cannot reach agreement
on the validity of such Damages by the end of the ten (10) day period following
the Notice Period, the dispute over the validity of such claim or liability (the
"Dispute") shall be settled as set forth in subparagraph (e) of this paragraph
17, with the non-prevailing party bearing the prevailing party's costs of
arbitration in the event any Dispute is resolved by arbitration.

               (2)  Seller's Remedies.  In the event Seller makes written
                    -----------------                                      
request to Buyer for the payment of Damages and Buyer fails to make the
requested payment within ten (10) days from the date of such written request
(said ten (10) day period hereinafter referred to as the "Notice Period"),
Seller shall have the right to require Buyer to pay Seller the full amount of
such Damages in cash within the ten (10) day period following the applicable
Notice Period (and Buyer shall be liable for such amount and for the payment of
such amount in full during such period); provided, however, that Buyer shall
have the option to provide written notice to Seller within the Notice Period
that Buyer disputes the validity of the Damages triggering the requirement for
payment by Buyer in cash, and in the event Seller and Buyer cannot reach
agreement on the validity of such Damages by the end of the ten (10) day period
following the Notice Period, the dispute over the validity of such Damages shall
be settled by arbitration, with the non-prevailing party bearing all of the
prevailing party's costs of arbitration. In the event an arbitration is required
pursuant to this subsection (2) of subparagraph (d), Buyer and Seller will each
select an arbitrator; those two arbitrators will then select a third arbitrator;
and the three arbitrators so chosen will determine the validity of the claim for
Damages. If Seller or Buyer delays in appointing an arbitrator when required,
and twenty (20) days or more has elapsed, the arbitrator appointed by the other
party shall arbitrate the dispute.Compete.

          (e)  Settlement of Disputes.
               ---------------------- 

               (1)  Disputes Involving Claims by Buyer Against the Seller (Not
                    ----------------------------------------------------------
Involving Third Parties).  In the event a Dispute arises which Dispute involves
- ------------------------                                                       
claims by Buyer against the Seller (i.e., not involving any third parties),
Buyer and the Seller shall settle the Dispute by submitting same to settlement
by arbitration.  In the event arbitration is required pursuant to this
subsection (1) of subparagraph (e), the Seller shall immediately place cash in
the full amount of the requested Damages into a separate escrow fund at Buyer's
direction pending resolution of the Dispute, and Buyer and the Seller will each
select an arbitrator; those two arbitrators will then select

                                       15
<PAGE>
 
a third arbitrator; and the three arbitrators so chosen will settle the Dispute
(the failure of Seller to place such amount in escrow shall cause the full
amount of Damages to be immediately due and payable by Seller in full).  In the
event the final settlement of the Dispute is for an amount less than the amount
in escrow, the balance shall be refunded to the Seller; and in the event the
final settlement of the Dispute is for an amount greater than the amount in
escrow, the Seller shall be liable for the excess, which amount shall be
immediately due and payable.

               (2)  Disputes Involving Claims Made by Third Parties.  In the
                    -----------------------------------------------    
event a Dispute arises which Dispute involves claims made by a third party or
parties (the "Third Party Claim"), Buyer shall give written notice to the Seller
as soon as practical after Buyer receives notice of a Third Party Claim. If any
lawsuit or enforcement action is filed against Buyer by a person asserting a
Third Party Claim, written notice shall be given to the Seller as promptly as is
practicable (in any event, within ten (10) days after the service of citation or
summons). After such notice, if the Seller shall acknowledge in writing to Buyer
that the Seller shall be obligated for such Third Party Claim and if the Seller
shall have placed the disputed amount of the Third Party Claim (such amount
shall be the full amount of the Third Party Claim or, in the exercise of the
Buyer's sole discretion, an amount less than the full amount of the Third Party
Claim) in a separate escrow fund at Buyer's direction pending resolution of the
Third Party Claim (the failure of Seller to place such amount in escrow shall
cause the full amount of Damages to be immediately due and payable by Seller in
full), then the Seller shall be entitled, if Seller so elects, to take control
of the defense and investigation of such lawsuit or action and to employ and
engage attorneys of its own choice to handle and defend the same, at the
Seller's cost, risk and expense, provided that the Seller and its counsel shall
proceed with diligence and in good faith with respect thereto. Buyer shall
cooperate in all reasonable respects with the Seller and their attorneys in the
investigation, trial and defense of such lawsuit or action and any appeal
arising therefrom; provided, however, that Buyer may, at Buyer's expense,
participate in the investigation, trial and defense of such lawsuit or action
and any appeal arising therefrom. If the Seller has acknowledged to Buyer its
obligation to Buyer hereunder and has placed the disputed amount of the Third
Party Claim in a separate escrow fund as required hereunder, Buyer shall not
settle such lawsuit or enforcement action without the prior written consent of
the Seller and, if the Seller has not so acknowledged its obligation or has
failed to place the required amount in escrow, Buyer shall not settle such
lawsuit or enforcement action without ten (10) days prior notice to the Seller.
In the event the final settlement of the Third Party Claim is for an amount less
than the amount in escrow, the balance shall be refunded to the Seller; and in
the event the final settlement of the Third Party Claim is for an amount greater
than the amount in escrow, the Seller shall be liable for the excess, which
amount shall be immediately due and payable.

          (f)  Threshold Amount.  Unless specifically provided for elsewhere in
               ----------------                                                
this Agreement, errors or omissions by the Seller pertaining to those items or
matters contained in or delivered pursuant to this Agreement shall not be deemed
breaches of warranty hereunder resulting in Damages unless such errors or
omissions exceed $10,000.00 in the aggregate.

     18.  Use of Corporate Name and Fictitious Name.  Seller agrees to take all
          -----------------------------------------                        
actions necessary to assist Buyer in obtaining the rights to utilize the
corporate name "Respiratory Home

person, shall be considered to be part of the Assets being purchased by Buyer
and shall, upon the consummation of the transactions contemplated by this
Agreement, be considered the property of Buyer.

     20.  Miscellaneous.  This Agreement shall not be assignable by Seller or

such instance, the right of offset shall not terminate until after the
settlement of such claim or claims. In the event the right of offset is extended
past the Release Date because a claim is in dispute, RoTech Stock having a value
of twice the amount of the claim asserted by RoTech using the per share closing
price of RoTech common stock as of January 3, 1996, shall continue to be held in
escrow past the Release Date until such claim is resolved , with the remaining
shares of RoTech Stock released to Shareholders within fifteen (15) days after

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

          (a)  Investment. The RoTech Stock which Shareholders are acquiring
               ----------                                                    
hereunder is being acquired for Shareholders' own account, not as a nominee or
agent, and not with a view to the sale or distribution of any part thereof for
the purposes of the Securities Act of 1933, as amended (the "Securities Act").

                                       3
<PAGE>
 
          (b)  Securities Not Registered. Shareholders understand that the
               -------------------------   
RoTech Stock has not been registered under the Securities Act on the ground that
the issuance of such securities hereunder is exempt from registration under the
Securities Act and that RoTech's reliance on such exemption is predicated on
Shareholders' representations set forth in this paragraph 5.

          (c)  Rule 144. Shareholders acknowledges that the RoTech Stock must be
               --------  
held indefinitely unless subsequently registered under the Securities Act or an
exemption from such registration is available. Shareholders are aware of the
provisions of Rule 144 promulgated under the Securities Act which permit limited
resale of securities purchased in a private placement subject to the
satisfaction of certain conditions. Rule 144 requires, among other things, that
current information on the issuer be available to the public and that the
Shareholders intending to sell under the Rule hold the shares for at least two
(2) years. In the event any of the RoTech Stock held by Shareholders becomes
eligible for sale pursuant to Rule 144, and an opinion of RoTech's counsel is
necessary to effectuate the transfer of RoTech Stock thereunder, Shareholders
shall bear the costs of obtaining such opinion of counsel, up to $275.00 for
each opinion of counsel issued in connection with transfers under Rule 144.
RoTech shall process any requests for transfer of RoTech Stock pursuant to Rule
144 in an efficient and prompt manner. Notwithstanding the foregoing, all costs
of the first request shall be fully paid by RoTech.

          (d)  Access to Data. Shareholders have received and reviewed
               --------------   
information about RoTech and have had an opportunity to ask questions of, and
receive answers from RoTech concerning RoTech's business, management, legal and
financial affairs and to obtain additional information (to the extent RoTech
possesses such information or could acquire it without unreasonable effort or
expense) necessary to verify the accuracy of any information furnished.
Shareholders also had the opportunity to inspect RoTech's facilities.
Shareholders understand that such discussions, as well as any written
information issued by RoTech, were intended to describe the aspects of RoTech's
business and prospects which it believes to be material, but were not
necessarily a thorough or exhaustive description.

          (e)  Risks. Shareholders are experienced in evaluating and investing
               -----  
in high risk companies such as RoTech and by reason of their business and
financial experience have the capacity to protect their own interests in
connection with the transactions contemplated by this Agreement and have the
ability to bear the economic risk of their investment.

          otherwise transferred, whether or not for consideration,
          by the purchaser except upon the issuance to the company 
          of a favorable opinion of its counsel and/or the submission 
          to the

                                       4
<PAGE>
 
          company of such other evidence as may be satisfactory to 
          counsel to the company, in either case to the effect that 
          any such transfer shall not be in violation of the 
          Securities Act of 1933, as amended, and applicable state 
          securities laws.

          (g)  No Registration Rights. Shareholders acknowledge that they

     4.    Right of Offset Against the Escrowed Amount.  In the event that: (i)

the RoTech pays for any debts or liabilities of the Corporation in excess of
$20,000.00 in the aggregate, other than as disclosed on the Schedule of
Liabilities attached hereto as Exhibit "C," (amount in excess of $20,000.00 is
herein referred to as the "Liabilities Deficiency"), or (ii) the aggregate value
of the Corporation's collectible accounts receivable as of December 31, 1995,
are determined to be less than $600,000.00, as determined by actual cash
collections of such receivables during the twelve (12) month period immediately

obligations or liabilities, except in the ordinary course of business;
discharged or satisfied any liens or encumbrances, except in the ordinary course
of business; declared or made any payment or distribution to any Shareholder or
purchased or redeemed any of its common capital stock or agreed to do so;
mortgaged, pledged or subjected to lien or encumbrance any of its assets; sold
or transferred any assets; suffered any damage or loss (whether or not covered
by insurance), materially affecting its properties; waived any rights of
substantial value; or entered into any

transaction other than in the ordinary course of business (the "Subsequent Event
Deficiency"), or (iv) any debts, liabilities or obligations of any nature
(whether absolute, accrued, contingent, or otherwise), other than those subject
to subparagraphs (i) through (iii) of this paragraph 4 (the "Obligations"),
become known, are uncovered or arise after the Effective Date, which Obligations
pertain to any actions, omissions, debts, liabilities or obligations of the
Corporation or any of its shareholders, created or arising on or before the
Effective Date (said Obligations hereinafter referred to as the "Contingent
Liability"); then, and in any of such events, RoTech shall have the right, for a
period of three (3) months from the Closing Date, to make offset against the
Escrowed Cash, in accordance with the terms and conditions of the Escrow
Agreement, in amounts from time to time equal to any Liabilities Deficiency,
Asset Value Deficiency, Subsequent Event Deficiency or Contingent Liability
which becomes known, is uncovered or arises during the three (3) month period
after the Closing Date, and Shareholders agree to pay said amounts to RoTech
immediately upon written request from RoTech to Shareholders.  During the three
(3) month period following the Closing Date, in the event RoTech makes written
request to Shareholders hereunder and Shareholders fails to make the requested
payment within ten (10) days from the date of such written request (said ten
(10) day period hereinafter referred to as the "Notice Period"), RoTech shall
have the right to make offset against the Escrowed Cash, in accordance with the
terms and conditions of the Escrow Agreement, in amounts from time to time equal

Event Deficiency or Contingent Liability which becomes known, is uncovered or
arises during the three (3) month period following the Closing Date, and the
Corporation agrees to allow RoTech to make offset against the Escrowed Cash as
herein provided.  In the event an offset against the Escrowed Cash is to occur,
an offset against one dollar ($1.00) of the Escrowed Cash shall have the effect
of reducing any amounts owed RoTech by Shareholders by one dollar ($1.00).
RoTech's right of offset against the Escrowed Cash shall terminate on that date
which is three (3) months from the Closing Date; provided, however, that
notwithstanding anything contained herein to the contrary, Shareholders shall
remain fully liable at all times for any and all debts and liabilities of
Shareholders, and in the event any debts or liabilities of Shareholders
(including but not limited to any Liabilities Deficiency, Asset Value
Deficiency, Subsequent Event Deficiency or Contingent Liability) become known,
are uncovered or arise at any time, including any time after the end of the
Escrow Period, RoTech may, at its option in the exercise of its sole discretion,
either refuse to pay any of such debts or liabilities of Shareholders or,
alternatively, may pay one or more of such debts or liabilities, in which case
Shareholders shall immediately reimburse RoTech for the full amount paid by
RoTech.  The RoTech shall be entitled to reimbursement from Shareholders of the
amount of any legal fees and expenses (including court costs and the costs of
appeal) incurred by RoTech to enforce the collection of amounts owed RoTech by
Shareholders hereunder.

outstanding shares of the Corporation, in that the Corporation has 100 shares of
its $10.00 par common capital stock outstanding, and Shareholders hold, in the
aggregate, 100 shares (the "Stock"), and there are no shares of any other class
of stock issued and outstanding.

     B.   The Corporation is engaged in the business of providing health care
services in the State of Texas (the "Business") and fully licensed by all
applicable agencies to do so.

     C.   The Boards of Directors of RoTech, Merger Sub and Rhema have
determined that it is in the best interests of their respective shareholders for

"Rhema, Inc."

the Corporation's collectible accounts receivable as of  December 31, 1995, are
less than $1,250,000, as determined by actual cash collections of such
receivables during the twelve (12) month period immediately following the

October 1, 1995, except as disclosed in writing, made expenditures or incurred
obligations or liabilities, except in the ordinary course of business;
discharged or satisfied any liens or encumbrances, except in the ordinary course
of business; declared or made any payment or distribution to Shareholders or

as disclosed on the Schedule of Shareholders, Distributions, and Exempted
Transactions attached hereto as Exhibit "F"; mortgaged, pledged or subjected to
lien or encumbrance any of its assets; sold or transferred any assets except in
the ordinary course of business; suffered any damage or loss (whether or not
covered by insurance), materially affecting its properties; waived any rights of
substantial value; or entered into any transaction other than in the ordinary

liabilities or obligations of the Corporation of any nature (whether absolute,
accrued, contingent, or otherwise), other than those subject to subparagraphs
(i) through (iii) of this paragraph 6 (the "Obligations"), become known to
RoTech, are uncovered or arise after the Closing Date, which Obligations pertain
to any actions, omissions, debts, liabilities or obligations of the Corporation
or any of its Shareholders (excluding deferred income tax liabilities and
assets), created or arising on or before the Closing Date (said Obligations
hereinafter referred to as the "Contingent Liability"); then, and in any of such
events, RoTech shall have the right to recover same from Shareholders on the
terms provided herein and in the Pledge Agreement and Escrow Agreement.
Shareholders jointly and severally agree to pay said amounts to RoTech
immediately upon written request from RoTech to Shareholders (the date of such
written request being hereinafter sometimes referred to as the "Request Date")
provided that the aggregate amounts under (i) - (iv) above plus the aggregate
Indemnifiable Damages under paragraph 14 exceed a threshold Claim amount of
$25,000.00 (the "Threshold Claim Amount") and do not exceed the Ceiling Amount,
as hereinafter defined.  During the twenty-four (24) month period following the
Closing Date, in the event RoTech makes written request to Shareholders
hereunder and Shareholders fail to make the requested payment within ten (10)
days from the date of such written request (said ten (10) day period hereinafter
referred to as the "Notice Period"), RoTech shall have the right to make offset

and conditions of the Pledge Agreement and Escrow Agreement, in amounts from
time to time equal to the amount of any Liabilities Deficiency, Asset Value
Deficiency, Subsequent Event Deficiency or Contingent Liability which becomes
known, is uncovered or arises during the twenty-four (24) month period following
the Closing Date.  Shareholders shall permit RoTech to make offset against the
RoTech Stock, and/or Cash  Collateral as herein provided, subject to the
Threshold Claim Amount limitations above.  In the event an offset against the
RoTech Stock is to occur, an offset against one (1) share of RoTech Stock shall
have the effect of reducing any amounts owed to RoTech by  $27.50.  RoTech's
right of offset against the RoTech Stock shall terminate no later than  December
31, 1997 (the "Release Date"); provided, however, that notwithstanding anything
contained in this Agreement or in the Pledge Agreement or Escrow Agreement to
the contrary, the right of offset shall extend past the Release Date in the
event a claim is in dispute at the time of the Release Date and, in such
instance, the right of offset shall not terminate until after the settlement of
such claim or claims.  In the event the right of offset is extended past the
Release

Date because a claim is in dispute, RoTech Stock, and/or Cash  Collateral having
a value of twice the amount of the claim asserted by RoTech (using   $27.50 as
previously defined) shall continue to be held in escrow past the Release Date
until such claim is resolved, with the remaining shares of RoTech Stock released
to Shareholders within fifteen (15) days after the Release Date.  RoTech shall
be entitled to reimbursement from Shareholders of the amount of any reasonable
legal fees and expenses (including court costs and the costs of appeal) incurred
by RoTech to enforce the collection of amounts owed RoTech by Shareholders
hereunder.

     7.   Characteristics of RoTech Stock.

          (a)  Investment.  The RoTech Stock which Shareholders are acquiring
               ----------                                                    
hereunder is being acquired for Shareholders' own account, not as a nominee or
agent, and not with a view to the sale or distribution of any part thereof for
the purposes of the Securities Act of 1933, as amended (the "Securities Act").

          (b)  Securities Not Registered.  Shareholders understand that the
               -------------------------                                   
RoTech Stock has not been registered under the Securities Act on the ground that
the issuance of such securities hereunder is exempt from registration under the
Securities Act and that RoTech's reliance on such exemption is predicated on
Shareholders' representations set forth in this paragraph 7.

          (c)  Rule 144.  Shareholders acknowledge that the RoTech Stock must be
               --------                                                         
held indefinitely unless subsequently registered under the Securities Act or an
exemption from such registration is available. Shareholders are aware of the
provisions of Rule 144 promulgated under the Securities Act which permit limited
resale of securities purchased in a private placement subject to the
satisfaction of certain conditions. Rule 144 requires, among other things, that
current information on the issuer be available to the public and that the
Shareholders intending to sell under the Rule hold the shares for at least two
(2) years.  In the event any of the RoTech Stock held by Shareholders become
eligible for sale pursuant to Rule 144, and an opinion of RoTech's counsel is
necessary to effectuate the transfer of RoTech Stock thereunder, Shareholders
shall bear the costs of obtaining such opinion of counsel, up to $275.00 for
each opinion of counsel issued in connection with transfers under Rule 144.
RoTech shall process any requests for transfer of RoTech Stock pursuant to Rule
144 in an efficient and prompt manner.

          (d)  Access to Data.  Shareholders have received and reviewed
               --------------                                          
information about RoTech and have had an opportunity to ask questions of, and
receive answers from RoTech concerning RoTech's business, management, legal and
financial affairs and to obtain additional information (to the extent RoTech
possesses such information or could acquire it without unreasonable effort or
expense) necessary to verify the accuracy of any information furnished.
Shareholders also had the opportunity to inspect RoTech' s facilities.
Shareholders understand that such discussions, as well as any written
information issued by RoTech, were intended to describe the aspects of RoTech's
business and prospects which it believes to be material, but were not
necessarily a thorough or exhaustive description.

          (e)  Risks.  Shareholders are experienced in evaluating and investing
               -----                                                           
in high risk companies such as RoTech and by reason of their business and
financial experience have the capacity to protect their own interests in
connection with the transactions contemplated by this Agreement and have the
ability to bear the economic risk of its investment.

          (f)  Restrictive Legends.  Each certificate representing RoTech Stock,
               -------------------                                              
including any securities issued as a dividend or other distribution with respect
to, in exchange for, or in replacement of such RoTech Stock shall be stamped or
otherwise imprinted with the following legend as well as any other legends
required by applicable state securities laws:

          The securities represented by this stock certificate or
          warrant have been acquired pursuant to an investment
          representation on the part of the purchaser thereof and
          shall not be sold, pledged, hypothecated, donated, or
          otherwise transferred, whether or not for consideration, by
          the purchaser except upon the issuance to the company of a
          favorable opinion of its counsel and/or the submission to
          the company of such other evidence as may be satisfactory to
          counsel to the company, in either case to the effect that
          any such transfer shall not be in violation of the
          Securities Act of 1933, as amended, and applicable state
          securities laws.

          (g)  No Registration Rights. Shareholders acknowledge that they
               ----------------------
possess no rights whatsoever to have any of the RoTech Stock registered.

     8.   Contingent Return of Shares of RoTech Stock; Put Option.
          ------------------------------------------------------- 

          (a)  Contingent Return of Shares of RoTech Stock.
               ------------------------------------------- 

               (i)  Terms of Return.  In the event the "First Two Year's Average
                    ---------------                                             
Operating Profits" of the "Acquired Entity" is less than ONE MILLION SIX HUNDRED
THOUSAND DOLLARS ($1,600,000.00) (the "Threshold Amount"), the number of shares
of RoTech Stock, and/or Cash  Collateral under the terms of the Stock Pledge and
Security Agreement, required to be distributed to Shareholders at the end of the
Escrow Period shall be reduced by a factor of .1818 (or in the case of Cash
Collateral, a cash equivalent of $5.00) for every ONE DOLLAR ($1.00) of the
First Two Year's Operating Profits during the Measurement Period below the
Threshold Amount, rounded to the nearest full share, with Buyer receiving
complete title to and possession of such Shares and/or Cash   Collateral.  For
example, in the event the First Two Year's Average Operating Profits of the
Acquired Entity during the Measurement Period is $1,500,000.00, the difference
from the Threshold Amount of $100,000.00 would result in a reduction hereunder
of  18,180 shares of RoTech Stock ($100,000 x .1818), (or in the case of Cash
Collateral the full $500,000 held in escrow, calculated at $5.00 x $100,000) at
the exchange rate of  $27.50 per share, with all of such shares (or in the case
of Cash Collateral

                                  6
<PAGE>
 
the full $500,000 held in escrow, calculated at $5.00 x $100,000) being
distributed to RoTech by the Escrow Agent upon final determination of the First
Two Year's Average Operating Profits and with the balance of  36,365 shares of
RoTech Stock (less any offsets pursuant to paragraph 6 hereof) delivered to the
Shareholders at the end of the Escrow Period.  In the event all of the assets or
capital stock of the RoTech is to be sold to a third party, the restriction
imposed by this subparagraph on the number of shares to be delivered to the
Shareholders at the end of the Escrow Period shall be null and void, and the
remainder of this subparagraph shall no longer apply, effective as of the
closing date of such sale by RoTech to a third party, unless RoTech successfully
negotiates as part of any such transaction, the preservation of all of the
remaining provisions of this subparagraph and Boyce D. Harbour continues to be
in charge of the supervision of financial reports of subsidiary identifiable or
division which succeeds to the business of the Corporation. In the event that
the First Two Years Average Operating Profits of the  Acquired Entity are less
than the Threshold Amount, the parties agree that the sole consequence under
this Agreement shall be the reduction in the number of shares of RoTech Stock,
and/or Cash  Collateral, required to be distributed by the Escrow Agent to
Shareholders at the end of the Escrow Period.  If said reduction results in a
distribution of all of the RoTech Stock, and/or Cash  Collateral, to RoTech,
there shall be no other liability of Shareholders to RoTech solely for failure
to equal or exceed the Threshold Amount.

               (ii) Certain Definitions.  The term "First Two Year's Average
                    -------------------

"Delivered RoTech Shares" shall mean the total number of shares of RoTech Stock
actually delivered to Shareholders by the Escrow Agent by the end of the Escrow
Period, reflecting all reductions pursuant to paragraph 8(a)(i) hereof and all
offsets pursuant to paragraph 6 hereof and therefore does not include the RoTech
Stock issued to the Shareholders under Paragraph 3 which are not subject to the
Escrow Agreement.  The Delivered RoTech Shares shall be issued with certificates
titled in the name of the  applicable Shareholders and having the restrictive
legend required by paragraph 7(f) hereof printed thereon.

to this Put Option must be delivered to the executive offices of RoTech, at the
address set forth   in paragraph 26 hereof (or at such other address as is
communicated by RoTech to Shareholders in writing). At 5:00 p.m., E.S.T.,

during the term of his Employment Agreement, shall be responsible for the
continued bookkeeping, and preparation of financial statements, for the business
of  Merger Sub.

     10.  Representations and Warranties by Shareholders.  Shareholders jointly
          ----------------------------------------------                       
and severally represent and warrant to RoTech that, to the best of each

obligations of the Corporation are listed on the Schedule of Liabilities
attached hereto as Exhibit "E" and such schedule accurately reflects all of
Corporation's "Existing Obligations" (as hereinafter defined) as of the Closing

absolute, accrued, contingent, or otherwise) on the Closing Date, including but
not limited to any and all accounts payable, trade payables, lease obligations,
indebtedness for borrowed money, accrued interest, contractual obligations, etc.

     4.    Right of Offset Against the RoTech Stock.  In the event that: (i)
           ----------------------------------------                         
RoTech pays for any debts or liabilities, of the Corporation in excess of
$250,000.00, (amount in excess of $250,000.00 is herein referred to as the
"Liabilities Deficiency"), or (ii) the aggregate value of the Corporation's
collectible accounts receivable as of January 31, 1996, are determined to be
less than $587,000.00, as determined by actual cash collections of such
receivables during the twelve (12) month period immediately following the
Effective Date (the "Asset Value Deficiency"), or (iii) the Corporation has,
since December 1, 1995 through the Closing Date, except as disclosed in writing,
made expenditures or incurred obligations or liabilities, except in the ordinary
course of business; discharged or satisfied any liens or encumbrances, except in
the ordinary course of business; declared or made any payment or distribution to
Shareholder or purchased or redeemed any of its common capital stock or agreed
to do so except as disclosed on the Schedule of Shareholders, Distributions, and
Exempted Transactions attached hereto as Exhibit "F"; mortgaged, pledged or
subjected to lien or encumbrance any of its assets; sold or transferred any
assets except in the ordinary course of business; suffered any damage or loss
(whether or not covered by insurance), materially affecting its properties;
waived any rights of substantial value; or entered into any transaction other
than in the ordinary course of business (the "Subsequent Event Deficiency"), or
(iv) any debts, liabilities or obligations of any nature (whether absolute,

                                       2
<PAGE>
 
accrued, contingent, or otherwise), other than those subject to subparagraphs
(i) through (iii) of this paragraph 4 (the "Obligations"), become known, are
uncovered or arise after the Effective Date, which Obligations pertain to any
actions, omissions, debts, liabilities or obligations of the Corporation or its
Shareholder, created or arising on or before the Effective Date (said
Obligations hereinafter referred to as the "Contingent Liability"); then, and in
any of such events, RoTech shall have the right to recover same from
Shareholder.  Shareholder agrees to pay said amounts to RoTech immediately upon
written request from RoTech to Shareholder (the date of such written request
being hereinafter sometimes referred to as the "Request Date"). During the
twenty-four (24) month period following the Effective Date, in the event RoTech
makes written request to Shareholder hereunder and Shareholder fails to make the
requested payment within ten (10) days from the date of such written request
(said ten (10) day period hereinafter referred to as the "Notice Period"),
RoTech shall have the right to make offset against the RoTech Stock, in
accordance with the terms and conditions of the Pledge Agreement and Escrow
Agreement, in amounts from time to time equal to the amount of any Liabilities
Deficiency, Asset Value Deficiency, Subsequent Event Deficiency or Contingent
Liability which becomes known, is uncovered or arises during the twenty-four
(24) month period following the Effective Date. Shareholder shall permit RoTech
to make offset against the RoTech Stock as herein provided.  In the event an
offset against the RoTech Stock is to occur, an offset against one (1) share of
RoTech Stock shall have the effect of reducing any amounts owed to RoTech by
$30.125.  RoTech's right of offset against the RoTech Stock shall terminate no
later than January 31, 1998 (the "Release Date"); provided, however, that
notwithstanding anything contained in this Agreement or in the Pledge Agreement
or Escrow Agreement to the contrary, the right of offset shall extend past the
Release Date in the event a claim is in dispute at the time of the Release Date
and, in such instance, the right of offset shall not terminate until after the
settlement of such claim or claims. In the event the right of offset is extended
past the Release Date because a claim is in dispute, RoTech Stock having a value
of twice the amount of the claim asserted by RoTech (using $31.125 as previously
defined) shall continue to be held in escrow past the Release Date until such
claim is resolved, with the remaining shares of RoTech Stock released to
Shareholder within fifteen (15) days after the Release Date.  RoTech shall be
entitled to reimbursement from Shareholder of the amount of any reasonable legal
fees and expenses (including court costs and the costs of appeal) incurred by
RoTech to enforce the collection of amounts owed RoTech by Shareholder
hereunder.

     5.    Characteristics of RoTech Stock.
           ------------------------------- 

           (a)   Investment.  The RoTech Stock which Shareholder is acquiring
                 ----------                                                  
hereunder is being acquired for Shareholder's own account, not as a nominee or
agent, and not with a view to the sale or distribution of any part thereof for
the purposes of the Securities Act of 1933, as amended (the "Securities Act").

           (b)   Securities Not Registered. Shareholder understands that the
                 -------------------------
RoTech Stock has not been registered under the Securities Act on the ground that
the issuance of such securities hereunder is exempt from registration under the
Securities Act and that RoTech's reliance on such exemption is predicated on
Shareholder's representations set forth in this paragraph 5.

                                       3
<PAGE>
 
           (c)   Rule 144.  Shareholder acknowledges that the RoTech Stock must 
                 --------
be held indefinitely unless subsequently registered under the Securities Act or
an exemption from such registration is available. Shareholder is aware of the
provisions of Rule 144 promulgated under the Securities Act which permit limited
resale of securities purchased in a private placement subject to the
satisfaction of certain conditions. Rule 144 requires, among other things, that
current information on the issuer be available to the public and that the
Shareholder intending to sell under the Rule hold the shares for at least two
(2) years. In the event any of the RoTech Stock held by Shareholder becomes
eligible for sale pursuant to Rule 144, and an opinion of RoTech's counsel is
necessary to effectuate the transfer of RoTech Stock thereunder, Shareholder
shall bear the costs of obtaining such opinion of counsel, up to $275.00 for
each opinion of counsel issued in connection with transfers under Rule 144.
RoTech shall process any requests for transfer of RoTech Stock pursuant to Rule
144 in an efficient and prompt manner.

           (d)   Access to Data. Shareholder has received and reviewed 
                 --------------
information about RoTech and have had an opportunity to ask questions of, and
receive answers from RoTech concerning RoTech's business, management, legal and
financial affairs and to obtain additional information (to the extent RoTech
possesses such information or could acquire it without unreasonable effort or
expense) necessary to verify the accuracy of any information furnished.
Shareholder also had the opportunity to inspect RoTech's facilities. Shareholder
understands that such discussions, as well as any written information issued by
RoTech, were intended to describe the aspects of RoTech's business and prospects
which it believes to be material, but were not necessarily a thorough or
exhaustive description.

           (e)   Risks.  Shareholder is experienced in evaluating and investing 
                 -----
in high risk companies such as RoTech and by reason of their business and
financial experience have the capacity to protect their own interests in
connection with the transactions contemplated by this Agreement and have the
ability to bear the economic risk of its investment.

           (f)   Restrictive Legends.  Each certificate representing RoTech 
                 -------------------
Stock, including any securities issued as a dividend or other distribution with
respect to, in exchange for, or in replacement of such RoTech Stock shall be
stamped or otherwise imprinted with the following legend as well as any other
legends required by applicable state securities laws:

           The securities represented by this stock certificate or warrant have
           been acquired pursuant to an investment representation on the part of
           the purchaser thereof and shall not be sold, pledged, hypothecated,
           donated, or otherwise transferred, whether or not for consideration,
           by the purchaser except upon the issuance to the company of a
           favorable opinion of its counsel and/or the submission to the company
           of such other evidence as may be satisfactory to counsel to the
           company, in either case to the effect that any such transfer shall
           not be in violation of the Securities Act of 1933, as amended, and
           applicable state securities laws. 

                                       4
<PAGE>
 
           (g)   No Registration Rights.  Shareholder acknowledges that he
                 ----------------------                                   
possesses no rights whatsoever to have any of the RoTech Stock registered.

     6.    Contingent Reduction of Shares of RoTech Stock; Put Option.
           ---------------------------------------------------------- 

           (a)   Contingent Reduction of Shares of RoTech Stock.
                 ---------------------------------------------- 

                 (1)  Terms of Reduction. In the event the "First Two Year's
                      ------------------
Average Operating Profits" of the Corporation is less than SIX HUNDRED THOUSAND
DOLLARS ($600,000.00) (the "Threshold Amount"), the number of shares of RoTech
Stock required to be delivered by RoTech to Shareholder at the end of the Escrow
Period shall be reduced by .1549 of shares of RoTech Stock for every ONE DOLLAR
($1.00) of the First Year's Operating Profits during the Measurement Period
below the Threshold Amount, rounded to the nearest full share, with RoTech
retaining complete title to and possession of such shares as if RoTech were at
all times the sole owner of such shares. For example, in the event the First Two
Year's Average Operating Profits of the Corporation during the Measurement
Period is $500,000.00), the difference from the Threshold Amount of $100,000.00
would result in a reduction hereunder of 15,590 shares of RoTech Stock ($100,000
x .1549), with all of such shares being returned to RoTech by the Escrow Agent
upon final determination of the First Two Year's Average Operating Profits and
with the balance of 4,327 shares of RoTech Stock (less any offsets pursuant to

obligations of any nature (whether absolute, accrued, contingent, or otherwise)
on the Effective Date, including but not limited to any and all accounts
payable, trade payables, lease obligations (except operating leases),
indebtedness for borrowed money, accrued interest, contractual obligations, etc.

     4.    Right of Offset Against the Escrowed Amount.   In the event that: (i)
           -------------------------------------------                          
RoTech pays for any debts or liabilities of Corporation in excess of
$1,640,595.00, other than as disclosed on the January 31, 1996 Financial
Statement and Schedule of Liabilities attached hereto as Exhibit "D," (amount in
excess of $1,640,595.00 is herein referred to as the "Liabilities Deficiency"),
or (ii) the aggregate value of the Corporation's collectible accounts receivable
as of January 31, 1996, are determined to be less than $459,761.00 as determined
by actual cash collections of such receivables during the twelve (12) month
period immediately following the Closing Date using commercially reasonable
collection efforts (the "Asset Value Deficiency"), or (iii) the Corporation has,
since January 31, 1996, made expenditures or incurred obligations or
liabilities, except in the ordinary course of business; discharged or satisfied
any liens or encumbrances, except in the ordinary course of business; declared
or made any payment or distribution to Shareholders or purchased or redeemed any
of its common capital stock or agreed to do so; mortgaged, pledged or subjected
to lien or encumbrance any of its assets, except in the ordinary course of
business; sold or transferred any assets; suffered any damage or loss (whether
or not covered by insurance), materially affecting its properties; waived any
rights of substantial value; or entered into any transaction other than in the
ordinary course of business (the "Subsequent Event Deficiency"), or (iii) any
debts, liabilities or obligations of any nature (whether absolute, accrued,
contingent, or otherwise), other than those subject to subparagraphs (i) through
(iii) of this paragraph 4 (the "Obligations"), become known, are uncovered or
arise after the Closing Date, which Obligations pertain to any actions,
omissions, debts, liabilities or obligations of the Corporation, created or

                                       2
<PAGE>
 
arising on or before the Closing Date (said Obligations hereinafter referred to
as the "Contingent Liability"); then, and in any of such events, RoTech shall
have the right, for a period of twelve (12) months from the Effective Date, to
make offset against the Escrowed Cash, in accordance with the terms and
conditions of the Escrow Agreement, in amounts from time to time equal to any
Liabilities Deficiency, Asset Value Deficiency, Subsequent Event Deficiency or
Contingent Liability which becomes known, is uncovered or arises during the
twelve (12) month period after the Effective Date,  (subject, however, in the
case of a "Dispute", to the provisions of paragraph 13 hereof applicable to a
"Dispute") and Shareholders agree to pay said amounts to RoTech immediately upon
written request from RoTech to Shareholders. During the twelve (12) month period
following the Effective Date, in the event RoTech makes written request to
Shareholders hereunder for Shareholders, and Shareholders fail to make the
requested payment within ten (10) days from the date of such written request
(said ten (10) day period hereinafter referred to as the "Notice Period"),
RoTech shall have the right to make offset against the Escrowed Cash, in
accordance with the terms and conditions of the Escrow Agreement, in amounts
from time to time equal to the amount of any Liabilities Deficiency, Asset Value
Deficiency, Subsequent Event Deficiency or Contingent Liability which becomes
known, is uncovered or arises during the twelve (12) month period following the
Effective Date (subject, however, in the case of a "Dispute", to the provisions
of paragraph 13 hereof applicable to a "Dispute"), and the Shareholders agree to
allow RoTech to make offset against the Escrowed Cash as herein provided.  In
the event an offset against the Escrowed Cash is to occur, an offset against
$1.00 of Escrowed Cash shall have the effect of reducing any amounts owed RoTech
by $1.00. RoTech's right of offset against the Escrowed Cash shall terminate on
that date which is twelve (12) months from the Effective Date (the "Release
Date"); provided, however, that notwithstanding anything contained in this
Agreement or in the Escrow Agreement to the contrary, the right of offset shall
extend past the Release Date in the event a claim is in dispute at the time of
the Release Date and, in such instance, the right of offset shall not terminate
until after the settlement of such claim or claims. In the event the right of
offset is extended past the Release Date because a claim is in dispute, Escrowed
Cash having a value equal to that amount which is one hundred fifty percent
(150%) of the amount of the claim asserted by RoTech shall continue to be held
in escrow past the Release Date until such claim is resolved, with the remaining
Escrowed Cash released to Shareholders within fifteen (15) days after the
Release Date. RoTech shall be entitled to reimbursement from Shareholders of the
amount of any reasonable legal fees and expenses (including court costs and the
costs of appeal) incurred by RoTech to enforce the collection of amounts owed
RoTech by Shareholders hereunder. Notwithstanding anything contained in this
paragraph 4 to the contrary, in the case of a "Dispute" (as defined in paragraph
13 hereof), the provisions of paragraph 13 hereof applicable to a "Dispute"
shall govern, and no offset against the Escrowed Cash shall occur until the
applicable "Dispute" is resolved in accordance with the provisions of paragraph
13 hereof.

     5.    Effective Date.  The effective date for the transaction contemplated
           --------------

period following the applicable Notice Period (and Shareholders shall be liable
for such amount and for the payment of such amount in full during such period);
provided, however, that in any of the events described in (i) through (iii) of
this subparagraph (d), Shareholders shall have the option to provide written
notice to RoTech within the Notice Period that Shareholders dispute the validity
of the Damages triggering the right of offset against the Escrowed Cash and/or
the requirement for payment by Shareholders in cash, and in the event RoTech and
Shareholders cannot reach agreement on the validity of such Damages by the end
of the ten (10) day period following the Notice Period, the dispute over the
validity of such claim or liability (the "Dispute") shall be settled as set
forth in subparagraph (e) of this paragraph 13, with the non-prevailing party
bearing the prevailing party's costs of arbitration in the event any Dispute is
resolved by arbitration.

                 (2)   Shareholder's Remedies.  In the event Shareholders make
                       ----------------------                                   
written request to RoTech for the payment of Damages and RoTech fails to make
the requested payment within ten (10) days from the date of such written request
(said ten (10) day period hereinafter referred to as the "Notice Period"),
Shareholders shall have the right to require RoTech to pay Shareholders the full
amount of such Damages in cash within the ten (10) day period following the
applicable Notice Period (and RoTech shall be liable for such amount and for the
payment of such amount in full during such period); provided, however, that
RoTech shall have the option to provide written notice to Shareholders within
the Notice Period that RoTech disputes the validity of the Damages triggering
the requirement for payment by RoTech in cash, and in the event Shareholders and
RoTech cannot reach agreement on the validity of such Damages by the end of the
ten (10) day period following the Notice Period, the dispute over the validity
of such Damages shall be settled as set forth in subparagraph (e) of this
paragraph 13, with the non-prevailing party bearing the prevailing party's costs
of arbitration in the event any dispute is resolved by arbitration.

           (e)   Settlement of Disputes.
                 ---------------------- 

                 (1)   Disputes Not Involving Third Parties.  In the event a
                       ------------------------------------             
Dispute arises which Dispute involves claims not involving any third parties,
RoTech and Shareholders shall settle the Dispute by submitting same to
settlement by arbitration. In the event arbitration is required pursuant to this
subsection (1) of subparagraph (e), RoTech and Shareholders will each select an
arbitrator within ten (10) days after the ten (10) day period following the
Notice Period; those two arbitrators will then select a third arbitrator; and
the three arbitrators so chosen will settle the Dispute.

                 (2)   Disputes Involving Claims Made by Third Parties.  In the
                       -----------------------------------------------     
event a Dispute arises which Dispute involves claims made by a third party or
parties (the "Third Party Claim"), RoTech or Shareholders shall give written
notice to the other ("Non-Aggrieved Party") as soon as practical after the
aggrieved party (the "Aggrieved Party") receives notice of a Third Party Claim.
If any lawsuit or enforcement action is filed against an Aggrieved Party by a
person asserting a Third Party Claim, written notice shall be given to the Non-
Aggrieved Party as promptly as is practicable (in any event, within ten (10)
days after the service of citation or summons). Upon such notice, RoTech and
Shareholders shall submit the Dispute to arbitration, with RoTech and
Shareholders each selecting an arbitrator; those two arbitrators then selecting
a third arbitrator; and the three arbitrators so chosen arbitrating the Dispute
as follows: (i) the Third Party Claim, solely for the purpose of determining the
party responsible for defending the Third Party Claim, shall be considered by
the arbitrators to be a valid claim (although such consideration is by no means
any admission by RoTech or Shareholders of any liability to any third party or
parties); (ii) assuming the Third Party Claim is determined by the arbitrators
to be valid, the arbitrators shall then decide whether RoTech or Shareholders is
the party responsible for paying the Third Party Claim in the event such Third
Party Claim is favorably contested by such third party or parties (with the
decision of such arbitrators final and binding as between RoTech and
Shareholders); (iii) in the event Shareholders are found by the arbitrators to
be the party responsible for paying the Third Party Claim, and Shareholders
refuse to immediately settle the Third Party Claim, Shareholders shall
immediately select one of the following two options: Option One: Shareholders
                                                     ----------    
can take on the sole defense, at their expense and risk, of the Third Party
Claim, provided Shareholders place in escrow in favor of RoTech adequate
collateral (as determined by the arbitrators upon consideration of all relevant
facts) protecting RoTech from an adverse judgment against RoTech in the event
RoTech is found to be liable to such third party or parties for any portion or
all of such Third Party Claim (in which case RoTech shall be immediately
reimbursed by Shareholders for any amount required to be paid by RoTech to such
third party or parties, with RoTech having such rights of offset as set forth in
paragraph 4 hereof and in the Escrow Agreement); or Option Two: Shareholders can
                                                    ---------- 
co-defend, at its expense and risk, the Third Party Claim with RoTech, with
Shareholders also responsible for paying all costs incurred by RoTech in
connection with such defense, including without limitation, the legal fees and
expenses of RoTech's counsel for its reasonable involvement in such defense (in
the event RoTech is found to be liable to such third party or parties for any
portion or all of such Third Party Claim, RoTech shall be immediately reimbursed
by Shareholders for any amount required  

                                       13
<PAGE>
 
to be paid by RoTech to such third party or parties, with RoTech having such
rights of offset as set forth in paragraph 4 hereof and in the Escrow
Agreement), provided, however, in the event Shareholders select this option,
Shareholders shall diligently attempt to have RoTech removed as a party to any
legal action involving the Third Party Claim (and, upon such removal, the
involvement of RoTech's counsel shall cease unless requested by Shareholders or
Shareholders' counsel); and (iv) in the event RoTech is found by the arbitrators
to be the party responsible for paying the Third Party Claim, and RoTech refuses
to immediately settle the Third Party Claim, RoTech shall immediately select one
of the following two options: Option One: RoTech can take on the sole defense,
                              ----------  
at its expense and risk, of the Third Party Claim provided RoTech places in
escrow in favor of Shareholders adequate collateral (as determined by the
arbitrators upon consideration of all relevant facts) protecting Shareholders
from an adverse judgment against Shareholders in the event Shareholders are
found to be liable to such third party or parties for any portion or all of such
Third Party Claim (in which case Shareholder shall be immediately reimbursed by
RoTech for any amount required to be paid by Shareholders to such third party or
parties); or Option Two: RoTech can co-defend, at its expense and risk, the
             ----------- 
Third Party Claim with Shareholders, with RoTech also responsible for paying all
costs incurred by Shareholders in connection with such defense, including
without limitation, the legal fees and expenses of Shareholders' counsel for its
reasonable involvement in such defense (in the event Shareholders are found to
be liable to such third party or parties for any portion or all of such Third
Party Claim, Shareholders shall be immediately reimbursed by RoTech for any
amount required to be paid by Shareholders to such third party or parties),
provided, however, in the event RoTech selects this option, RoTech shall
diligently attempt to have Shareholders removed as a party to any legal action
involving the Third Party Claim (and, upon such removal, the involvement of
Shareholders' counsel shall cease unless requested by RoTech or RoTech's
counsel). Any party responsible for defending a Third Party Claim shall proceed
with diligence and in good faith with respect thereto.

                 (3)   Failure to Appoint Arbitrator.  If either party delays in
                       -----------------------------                            
appointing an arbitrator when required by this subparagraph (e) of this
paragraph 13, and another twenty (20) day period has elapsed in which such party
does not cure such failure by appointing an arbitrator, the arbitrator appointed
by the other party shall arbitrate the Dispute, and in such case such
arbitrator's decision shall be binding upon all parties.

     14.   Miscellaneous - Expense.  The parties agree to pay individually
           -----------------------                                        
whatever expenses they incur in connection with this Agreement.  In connection
with any action arising out of or concerning this Agreement, the prevailing
party shall be entitled to recover reasonable attorneys' fees and costs, whether
incurred at trial, on appeal or otherwise.

     15.   Amendment and Waiver.  This Agreement may be amended or modified at
           --------------------                                               
any time in all respects by an instrument in writing executed by Shareholders
and RoTech.

     16.   Assignment.  Neither this Agreement nor any right created hereby
           ----------

hereinafter referred to as the "Contingent Liability"); then, and in any of such
events, RoTech shall have the right, for a period of twelve (12) months from the
Effective Date, to make offset against the Escrowed Cash, in accordance with the
terms and conditions of the Escrow Agreement, in amounts from time to time equal
to any Liabilities Deficiency, Asset Value Deficiency, Subsequent Event
Deficiency or Contingent Liability which becomes known, is uncovered or arises
during the twelve (12) month period after the Effective Date, (subject, however,

(said ten (10) day period hereinafter referred to as the "Notice Period"),
RoTech shall have the right to make offset against the Escrowed Cash, in
accordance with the terms and conditions of the Escrow Agreement, in amounts
from time to time equal to the amount of any Liabilities Deficiency, Asset Value

<PAGE>
 
"Dispute"), and the Shareholders agree to allow RoTech to make offset against
the Escrowed Cash as herein provided. In the event an offset against the
Escrowed Cash is to occur, an offset against $1.00 of Escrowed Cash shall have
the effect of reducing any amounts owed RoTech by $1.00. RoTech's right of
offset against the Escrowed Cash shall terminate on that date which is twelve
(12) months from the Effective Date (the "Release Date"); provided, however,
that notwithstanding anything contained in this Agreement or in the Escrow
Agreement to the contrary, the right of offset shall extend past the Release
Date in the event a claim is in dispute at the time of the Release Date and, in
such instance, the right of offset shall not terminate until after the
settlement of such claim or claims. In the event the right of offset is extended
past the Release Date because a claim is in dispute, Escrowed Cash having a
value equal to that amount which is one hundred fifty percent (150%) of the
amount of the claim asserted by RoTech shall continue to be held in escrow past
the Release Date until such claim is resolved, with the remaining Escrowed Cash
released to Shareholders within fifteen (15) days after the Release Date. RoTech
shall be entitled to reimbursement from Shareholders of the amount of any
reasonable legal fees and expenses (including court costs and the costs of
appeal) incurred by RoTech to enforce the collection of amounts owed RoTech by
Shareholders hereunder. Notwithstanding anything contained in this paragraph 4
to the contrary, in the case of a "Dispute" (as defined in paragraph 13 hereof),
the provisions of paragraph 13 hereof applicable to a "Dispute" shall govern,
and no offset against the Escrowed Cash shall occur until the applicable
"Dispute" is resolved in accordance with the provisions of paragraph 13 hereof.

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

                 -------- 
                 (1)   RoTech's Remedies. In the event RoTech makes written
                       -----------------
request to Shareholders for the payment of Damages and Shareholders fail to make
the requested payment within ten (10) days from the date of such written request
(said ten (10) day period hereinafter referred to as the "Notice Period"),
RoTech shall have the right: (i) if such request is made during the Escrow
Period and Escrowed Cash is sufficient to pay such Damages in full is held by
RoTech in escrow, to make offset against the Escrowed Cash, in accordance with
the terms and conditions of this Agreement and the related Escrow Agreement;
(ii) if such request is made during the Escrow Period and the amount of Escrowed
Cash held by RoTech in escrow is insufficient to pay such Damages in full, to
first make offset against any Escrowed Cash held in escrow and then to require
Shareholders to pay RoTech the remaining balance in cash within the ten (10) day
period following the applicable Notice Period (and Shareholders shall be liable
for such balance and for the payment of such balance in full during such
period); and (iii) if such request is made during the Escrow Period and no
Escrowed Cash is being held in escrow by RoTech at the time of such request, or
if such request is made after the Escrow Period, to require the Shareholders to
pay RoTech the full amount of such Damages in cash within the ten (10) day
period following the applicable Notice Period (and Shareholders shall be liable
for such amount and for the payment of such amount in full during such period);
provided, however, that in any of the events described in (i) through (iii) of
this subparagraph (d), Shareholders shall have the option to provide written
notice to RoTech within the Notice Period that Shareholders dispute the validity
of the Damages triggering the right of offset against the Escrowed Cash and/or
the requirement for payment by Shareholders in cash, and in the event RoTech and
Shareholders cannot reach agreement on the validity of such Damages by the end
of the ten (10) day period following the Notice Period, the dispute over the
validity of such claim or liability (the "Dispute") shall be settled as set
forth in subparagraph (e) of this paragraph 13, with the non-prevailing party
bearing the prevailing party's costs of arbitration in the event any Dispute is
resolved by arbitration.

                 (2)   Shareholder's Remedies.  In the event Shareholders make
                       ----------------------                                 
written request to RoTech for the payment of Damages and RoTech fails to make
the requested payment within ten (10) days from the date of such written request
(said ten (10) day period hereinafter referred to as the "Notice Period"),
Shareholders shall have the right to require RoTech to pay Shareholders the full
amount of such Damages in cash within the ten (10) day period following the
applicable Notice Period (and RoTech shall be liable for such amount and for the
payment of
                                       12
<PAGE>
 
such amount in full during such period); provided, however, that RoTech shall
have the option to provide written notice to Shareholders within the Notice
Period that RoTech disputes the validity of the Damages triggering the
requirement for payment by RoTech in cash, and in the event Shareholders and
RoTech cannot reach agreement on the validity of such Damages by the end of the
ten (10) day period following the Notice Period, the dispute over the validity
of such Damages shall be settled as set forth in subparagraph (e) of this
paragraph 13, with the non-prevailing party bearing the prevailing party's costs
of arbitration in the event any dispute is resolved by arbitration.

           (e)   Settlement of Disputes.
                 ---------------------- 

                 (1)   Disputes Not Involving Third Parties.  In the event a
                       ------------------------------------                    
Dispute arises which Dispute involves claims not involving any third parties,
RoTech and Shareholders shall settle the Dispute by submitting same to
settlement by arbitration. In the event arbitration is required pursuant to this
subsection (1) of subparagraph (e), RoTech and Shareholders will each select an
arbitrator within ten (10) days after the ten (10) day period following the
Notice Period; those two arbitrators will then select a third arbitrator; and
the three arbitrators so chosen will settle the Dispute.

                 (2)   Disputes Involving Claims Made by Third Parties.  In the
                       -----------------------------------------------    
event a Dispute arises which Dispute involves claims made by a third party or
parties (the "Third Party Claim"), RoTech or Shareholders shall give written
notice to the other ("Non-Aggrieved Party") as soon as practical after the
aggrieved party (the "Aggrieved Party") receives notice of a Third Party Claim.
If any lawsuit or enforcement action is filed against an Aggrieved Party by a
person asserting a Third Party Claim, written notice shall be given to the Non-
Aggrieved Party as promptly as is practicable (in any event, within ten (10)
days after the service of citation or summons). Upon such notice, RoTech and
Shareholders shall submit the Dispute to arbitration, with RoTech and
Shareholders each selecting an arbitrator; those two arbitrators then selecting
a third arbitrator; and the three arbitrators so chosen arbitrating the Dispute
as follows: (i) the Third Party Claim, solely for the purpose of determining the
party responsible for defending the Third Party Claim, shall be considered by
the arbitrators to be a valid claim (although such consideration is by no means
any admission by RoTech or Shareholders of any liability to any third party or
parties); (ii) assuming the Third Party Claim is determined by the arbitrators
to be valid, the arbitrators shall then decide whether RoTech or Shareholders
is the party responsible for paying the Third Party Claim in the event such
Third Party Claim is favorably contested by such third party or parties (with
the decision of such arbitrators final and binding as between RoTech and
Shareholders); (iii) in the event Shareholders are found by the arbitrators to
be the party responsible for paying the Third Party Claim, and Shareholders
refuse to immediately settle the Third Party Claim, Shareholders shall
immediately select one of the following two options: Option One: Shareholders
                                                     -----------  
can take on the sole defense, at their expense and risk, of the Third Party
Claim, provided Shareholders place in escrow in favor of RoTech adequate
collateral (as determined by the arbitrators upon consideration of all relevant
facts) protecting RoTech from an adverse judgment against RoTech in the event
RoTech is found to be liable to such third party or parties for any portion or
all of such Third Party Claim (in which case RoTech shall be immediately
reimbursed by Shareholders for any amount required to be paid by RoTech to such

                                       13
<PAGE>
 
third party or parties, with RoTech having such rights of offset as set forth in
paragraph 4 hereof and in the Escrow Agreement); or Option Two: Shareholders can
                                                    ----------
co-defend, at its expense and risk, the Third Party Claim with RoTech, with
Shareholders also responsible for paying all costs incurred by RoTech in
connection with such defense, including without limitation, the legal fees and
expenses of RoTech's counsel for its reasonable involvement in such defense (in
the event RoTech is found to be liable to such third party or parties for any
portion or all of such Third Party Claim, RoTech shall be immediately reimbursed
by Shareholders for any amount required to be paid by RoTech to such third party
or parties, with RoTech having such rights of offset as set forth in paragraph 4
hereof and in the Escrow Agreement), provided, however, in the event
Shareholders select this option, Shareholders shall diligently attempt to have
RoTech removed as a party to any legal action involving the Third Party Claim
(and, upon such removal, the involvement of RoTech's counsel shall cease unless
requested by Shareholders or Shareholders' counsel); and (iv) in the event
RoTech is found by the arbitrators to be the party responsible for paying the
Third Party Claim, and RoTech refuses to immediately settle the Third Party
Claim, RoTech shall immediately select one of the following two options: Option
                                                                         ------ 
One: RoTech can take on the sole defense, at its expense and risk, of the Third
- ---
Party Claim provided RoTech places in escrow in favor of Shareholders adequate
collateral (as determined by the arbitrators upon consideration of all relevant
facts) protecting Shareholders from an adverse judgment against Shareholders in
the event Shareholders are found to be liable to such third party or parties for
any portion or all of such Third Party Claim (in which case Shareholder shall be
immediately reimbursed by RoTech for any amount required to be paid by
Shareholders to such third party or parties); or Option Two: RoTech can co-
                                                 ----------
defend, at its expense and risk, the Third Party Claim with Shareholders, with
RoTech also responsible for paying all costs incurred by Shareholders in
connection with such defense, including without limitation, the legal fees and
expenses of Shareholders' counsel for its reasonable involvement in such defense
(in the event Shareholders are found to be liable to such third party or parties
for any portion or all of such Third Party Claim, Shareholders shall be
immediately reimbursed by RoTech for any amount required to be paid by
Shareholders to such third party or parties), provided, however, in the event
RoTech selects this option, RoTech shall diligently attempt to have Shareholders
removed as a party to any legal action involving the Third Party Claim (and,
upon such removal, the involvement of Shareholders' counsel shall cease unless
requested by RoTech or RoTech's counsel). Any party responsible for defending a
Third Party Claim shall proceed with diligence and in good faith with respect
thereto.

                 (3)   Failure to Appoint Arbitrator.  If either party delays in
                       -----------------------------                            
appointing an arbitrator when required by this subparagraph (e) of this
paragraph 13, and another twenty (20) day period has elapsed in which such party
does not cure such failure by appointing an arbitrator, the arbitrator appointed
by the other party shall arbitrate the Dispute, and in such case such
arbitrator's decision shall be binding upon all parties.

     14.   Miscellaneous - Expense.  The parties agree to pay individually
           -----------------------                                        
whatever expenses they incur in connection with this Agreement.  In connection
with any action arising out of or concerning this Agreement, the prevailing
party shall be entitled to recover reasonable attorneys' fees and costs, whether
incurred at trial, on appeal or otherwise.

shall be assignable by Shareholders or RoTech without the prior written consent
of the other, except for an assignment incident to a merger, consolidation or
reorganization, or, in the event of any of the Shareholder's death, a transfer
