     This Prospectus contains certain forward-looking statements within the
meaning of the Securities Act. Actual results could differ materially from those
projected in the forward-looking statements as a result of certain of the risk
factors set forth below and certain other factors set forth elsewhere in this

Shares offered hereby.

DEPENDENCE ON MEDICARE, MEDICAID AND OTHER SOURCES OF REIMBURSEMENT

     The Company is reimbursed for dialysis services primarily at fixed rates as
established in advance under the Medicare End Stage Renal Disease ("ESRD")
program.  Under this program, once a patient becomes eligible for Medicare
reimbursement, Medicare is responsible for payment of approximately 80% of the
composite rate for dialysis treatment.  The composite rate is determined by the
Health Care Financing Administration ("HCFA") for reimbursement of Medicare
patients.  Approximately 65% and 58% of the Company's net patient revenue during
the year ended December 31, 1995 and the six months ended June 30, 1996,
respectively, was funded by Medicare.  Since 1983, numerous Congressional
actions have resulted in changes in the Medicare composite reimbursement rate
from a national average of $138 per treatment in 1983 to a low of $125 per
treatment on average in 1986 and to approximately $126 per treatment on average
at present. The Company is not able to predict whether future rate changes will
be made. Reductions in composite rates could have a material adverse effect on
the Company's revenues and net earnings.  Furthermore, increases in operating
costs that are subject to inflation, such as labor and supply costs, without a
compensating increase in prescribed rates, may adversely affect the Company's
earnings in the future. The Company is also unable to predict whether certain
services, as to which the Company is currently separately reimbursed, may in the
future be included in the Medicare composite rate.

     Since June 1, 1989, the Medicare ESRD program has provided reimbursement
for the administration to dialysis patients of erythropoietin ("EPO"), a drug
that is beneficial in the treatment of anemia, a complication experienced by
most dialysis patients.  Most of the Company's dialysis patients receive EPO.
Revenues associated with the administration of EPO are significant to the
Company and the Company cannot predict future changes in the reimbursement
rate, the typical dosage per administration or the cost of EPO.  EPO is produced
by only one manufacturer, and any interruption of supply could adversely affect
the Company's operations.

     All of the states in which the Company currently operates dialysis centers
provide Medicaid (or comparable) benefits to qualified recipients to supplement
their Medicare entitlement.  The Company estimates that approximately 4% of its
net patient revenue during the fiscal year ended December 31, 1995 and during
the six months ended June 30, 1996 was funded by Medicaid or comparable state
programs.  The Medicaid programs are subject to statutory and regulatory
changes, administrative rulings, interpretations of policy and governmental
funding restrictions, all of which may have the effect of decreasing program
payments, increasing costs or modifying the way the Company operates its
dialysis business.

                                       3
<PAGE>
 
     Approximately 31% and 38% of the Company's net patient revenue during the
fiscal year ended December 31, 1995 and during the six months ended June 30,
1996, respectively, was from sources other than Medicare and Medicaid.  These
sources include payments from third-party, non-government payors and payments
from hospitals with which the Company has agreements for the provision of
inpatient acute dialysis treatments, in each case at rates that generally exceed
the Medicare and Medicaid rates.  Any restriction or reduction of the Company's
ability to charge for such services at rates in excess of those paid by Medicare
would adversely affect the Company's net patient revenue and net income.  The
Company is unable to quantify or predict the degree, if any, of the risk of
reductions in payments under these various payment plans.

     In March 1996, HCFA published a request for proposals from managed care
companies to arrange for the treatment of ESRD patients on a large scale for the
first time.  Currently, managed care companies are only permitted to arrange for
the treatment of existing members in their programs who develop ESRD.  Formal
bids were due on or before May 17, 1996.  HCFA has announced its intention to
choose, from those companies submitting proposals, approximately four managed
care companies that will be allowed to recruit ESRD patients beginning in mid-
1997 in a test program.  The results of the test program will determine whether
HCFA will open up the market to additional managed care companies.  The Company
is unable to predict whether the test program will result in large numbers of
ESRD patients enrolling in managed care programs, or the impact of the
enrollment of ESRD patients in managed care programs on the Company.  The
widespread introduction of managed care to dialysis services could result in a
reduction in the rates of reimbursement for the Company's services, which could
have a material adverse effect on the Company's revenues and net earnings.

OPERATIONS SUBJECT TO, AND POTENTIAL EFFECTS OF, GOVERNMENTAL REGULATION

     The Company is subject to extensive regulation by both the Federal
government and the states in which it conducts its business, including the
illegal remuneration provisions of the Social Security Act and similar state
laws, which impose civil and criminal sanctions on persons who solicit, offer,
receive or pay any remuneration, directly or indirectly, in consideration for
referring a patient for treatment that is paid for in whole or in part by
Medicare, Medicaid or similar state programs. In July 1991 and November 1992,
the Federal government published regulations that provide exceptions or safe
harbors for certain business transactions.  Transactions that are structured
within the safe harbors are deemed not to violate the illegal remuneration
provisions.  Transactions that do not satisfy all elements of a relevant safe
harbor do not necessarily violate the illegal remuneration statute, but may be
subject to greater scrutiny by enforcement agencies.  The arrangements between
the Company and the physician directors of its dialysis centers ("Physician
Directors") have been structured to satisfy the elements of the applicable safe
harbors, but there can be no assurance that they will not be found to violate
the illegal remuneration provisions.  However, certain of the Company's
Physician Directors from whom the Company has acquired dialysis centers have
received shares of the Company's Common Stock in full or partial consideration
for such acquisitions, and other Physician Directors may have purchased shares
of the Company's Common Stock in the open market, and such security ownership
does not fall within any of the safe harbors.  Although the Company has never
been challenged under these statutes and believes it complies in all material
respects with these and all other applicable

                                       4
<PAGE>
 
laws and regulations, there can be no assurance that the Company will not be
required to change its practices or relationships with its Physician Directors
or that the Company will not experience material adverse effects as a result of
any such challenge.

     The Omnibus Budget Reconciliation Act of 1989 includes certain provisions
("Stark I") that restrict physician referrals for clinical laboratory services
to entities with which a physician or an immediate family member has a financial
relationship.  In August 1995, HCFA published regulations interpreting Stark I.
The regulations specifically provide that services furnished in an ESRD facility
that are included in the composite billing rate are excluded from the coverage
of Stark I.  The Company believes that the language and legislative history of
Stark I indicate that Congress did not intend to include laboratory services
provided incidental to dialysis services within the Stark I prohibition;
however, laboratory services not included in the Medicare compos ite rate could
be included within the coverage of Stark I.  Violations of Stark I are
punishable by civil penalties, which may include exclusion or suspension of a
provider from future participa tion in Medicare and Medicaid programs and
substantial fines.  Due to the breadth of the statutory provisions, it is
possible that the Company's practices might be challenged under this law.

     The Omnibus Budget Reconciliation Act of 1993 includes certain provisions
("Stark II") that restrict physician referrals for certain designated health
services to entities with which a physician or an immediate family member has a
financial relationship.  The Company believes that the language and legislative
history of Stark II indicate that Congress did not intend to include dialysis
services and the services and items provided incident to dialysis services
within the Stark II prohibitions; however, certain services, including the
provision of, or arrangement and assump tion of financial responsibility for,
outpatient prescription drugs, including EPO, and clinical laboratory services,
could be construed as designated health services within the meaning of Stark II.
Violations of Stark II are punishable by civil penalties, which may include
exclusion or suspension of the provider from future participation in Medicare
and Medicaid programs and substantial fines.  Due to the breadth of the
statutory provisions and the absence of regulations or court decisions
addressing the specific arrangements by which the Company conducts its business,
it is possible that the Company's practices might be challenged under these
laws.

     The Clinton administration's health care reform proposals, and other health
care reform proposals in general, have not addressed the Medicare ESRD program.
Nonetheless, health care reform in general, and Medicare reform in particular,
could bring radical change in the financing and regulation of the health care
business, and the Company is unable to predict the effect of such changes on its
future operations.  Changes in reimbursement levels under Medicare or Medicaid
and changes in applicable governmental regulations could significantly affect
the Company's results of operations.  It is uncertain at this time what
legislation on health care reform, if any, will ultimately be implemented or
whether other changes in the administration or interpretation of governmental
health care programs will occur. There can be no assurance that future health
care legislation or other changes in the administration or interpretation of
governmental health care programs will not have a material adverse effect on the
results of operations of the Company.

RISKS INHERENT IN GROWTH STRATEGY

     The Company's business strategy depends in significant part on its ability
to acquire or develop additional dialysis centers.  This strategy is dependent
on the continued availability of suitable acquisition candidates and subjects
the Company to the risks inherent in assessing the value, strengths and
weaknesses of acquisition candidates, integrating and managing the operations of
acquired companies and identifying suitable locations for additional facilities.
The Company's growth is expected to place significant demands on the Company's
financial resources. The Company plans to borrow a significant portion of the
funds needed to acquire or develop centers in the future.  While the Company's
credit facility with a consortium of bank lenders (the "Credit Agreement")
includes up to $100,000,000 for acquisition and development activities and
general working capital requirements, and the Company completed an offering of
$125,000,000 principal amount of 5 5/8% Convertible Subordinated Notes due 2006
on June 12, 1996, a portion of the proceeds of which will be used to fund future
acquisitions, additional equity or debt financings are expected to be required
in order for the Company to fund its expansion plans.  There can be no assurance
that the Company will continue to be able to obtain necessary financing on
acceptable terms for the acquisition or development of centers or that the
Company will otherwise be successful in acquiring or developing new centers.  No
assurance can be given that the Company will make any additional acquisitions or
develop any additional centers.

DEPENDENCE ON PHYSICIAN REFERRALS

     The Company's centers are dependent upon referrals of ESRD patients for
treatment by physicians specializing in nephrology and practicing in the
communities served by the Company's dialysis centers.  As is customary in the
dialysis industry, at each center one or a few physicians account for all or a
significant portion of the patient referral base.  The loss of one or more key
referring physicians at a particular center could have a material adverse impact
on the operations of that center and could adversely affect the Company's
overall operations.  Financial relationships with physicians and other referral
sources are highly regulated.  The illegal remuneration provisions of the
Social Security Act and similar state laws prohibit contracts for referrals.

COMPETITION

     The dialysis industry is fragmented and highly competitive, particularly
from the standpoint of competition for acquisition of existing dialysis centers
and developing relationships with referring physicians.  Competition for
qualified physicians to act as Physician Directors is also high.  Also, a number
of health care providers have entered or may decide to enter the kidney dialysis
business.  Certain of the Company's competitors have substantially greater
financial resources than the Company and may compete with the Company for
acquisitions and for development of centers in markets targeted by the Company.
There can be no assurance that the Company can continue to compete effectively
with such providers.  In addition, competition has increased the cost of
acquiring existing dialysis facilities and there can be no assurance that these
costs will not continue to increase as a result of future industry
consolidation.  Furthermore, some of the Company's centers are in urban areas
where there are many competing facilities in close proximity.  The Company has
also experienced competition from the establishment of facilities by former
Physician Directors and referring physicians.

                                       6
<PAGE>
 
DEPENDENCE ON KEY PERSONNEL

     The Company is dependent on certain key management personnel, particularly
its President and Chief Executive Officer, Robert L. Mayer, Jr., the loss of
whom could have an adverse effect on the Company's business.  Moreover, the
Company believes that its future success will be significantly dependent on its
ability to attract and retain qualified physicians to serve as Physician
Directors of its dialysis centers.  In addition, the Company will need to
continue to attract and retain highly skilled nurses, competition for whom is
intense.

VOLATILITY OF MARKET PRICE OF COMMON STOCK

     The trading price of the Common Stock is subject to significant
fluctuations in response to variations in quarterly operating results, general
conditions in the health care industry, changes in the regulatory environment
and other factors.

SHARES ELIGIBLE FOR FUTURE SALE

     Of the 24,258,767 outstanding shares of Common Stock as of August 16, 1996,
21,552,311 shares were freely tradeable and 2,706,456 shares were restricted and
therefore not freely tradeable.  Of the restricted shares, 2,206,321 shares had
been registered under the Securities Act on shelf registration statements and
were eligible for sale in the public market as of August 16, 1996.  An
additional 482,377 of the restricted shares are the Shares offered by this
Prospectus, which have also been registered on a shelf registration statement.
The remaining 17,758 restricted shares and 1,740,488 shares subject to exercise
of outstanding options as of August 16, 1996 will become eligible for future
sale in the public market at prescribed times pursuant to applicable regulations
and, with respect to options, as they are exercised.  Sales of a substantial
number of shares of Common Stock in the public market following the offering
made hereby could adversely affect prevailing market prices of the Common Stock.

POTENTIAL ANTI-TAKEOVER EFFECTS OF DELAWARE LAW AND BY-LAW PROVISIONS; POSSIBLE
ISSUANCES OF PREFERRED STOCK

     Certain provisions of Delaware law and the Company's By-Laws could delay or
impede the removal of incumbent directors and could make it more difficult for a
third party to acquire, or could discourage a third party from attempting to
acquire, control of the Company.  Such provisions could limit the price that
certain investors might be willing to pay in the future for  shares of the
Company's Common Stock.  The Company's Board of Directors is divided into three
classes, with directors in each class elected for three-year terms.  The By-Laws
impose various procedural and other requirements that could make it more
difficult for stockholders to effect certain corporate actions. Shares of

approval on such terms and conditions, and having such rights, privileges and
preferences, as the Board may determine.  The rights of the holders of Common
Stock will be subject to, and may be adversely affected by, the rights of the
holders of any preferred stock that may be issued in the future. The Company has
no current plans to issue any shares of preferred stock.

                                 THE COMPANY

     The Company is a leading, high-quality provider of dialysis treatments
and ancillary services to patients suffering from chronic kidney failure,
primarily in its freestanding outpatient dialysis treatment centers or in the
patient's home.  The Company currently operates 101 outpatient dialysis centers
in 21 states and the District of Columbia and one dialysis center in the
Republic of Argentina.  As of July 31, 1996, the Company provided dialysis
services to approximately 7,000 patients.  The Company also provided ancillary
medications and services to patients, the most significant of which is the
administration of EPO, a protein used to treat anemia, a complication
experienced by most dialysis patients.  In addition, the Company provided
inpatient acute dialysis services to 79 hospitals located in its service areas
as of July 31, 1996.  The Company has expanded rapidly, primarily through
acquisitions, increasing the number of dialysis centers in its network from 15
as of December 31, 1991 to its current level of 102 centers.

     The Company is a Delaware corporation formed on August 11, 1988.  Its
principal executive offices are located at 1180 West Swedesford Road, Building
2, Suite 300, Berwyn, Pennsylvania 19312, and its telephone number is (610) 
644-4796.

                              SELLING STOCKHOLDERS

     The Shares covered by this Prospectus are, or may be, offered by the
Selling Stockholders.  The Selling Stockholders are Ronald A. Sinicrope, M.D.,
Richard F. Walker, Jr., M.D. and Scott E. Dean, M.D.

     The Selling Stockholders consist of the former shareholders of two
corporations (collectively, the "Florida Companies"), which operated a total of
two dialysis centers located in Florida.  The Company acquired each of the
Florida Companies on July 23, 1996.  The acquisition was structured as the
merger of each of the Florida Companies into a wholly owned subsidiary of the
Company.  As a result of these mergers, the outstanding capital stock of the
Florida Companies, all of which was held by the Selling Stockholders, was
converted into an aggregate of 482,377 shares of the Company's Common Stock.

     None of the Selling Stockholders, nor any affiliate of any of the
Selling Stockholders, is now, or ever has been, an officer, director or employee
of the Company.  Nephrology Associates, P.A., a physician practice group with
which each of the Selling Stockholders is affiliated, however, provides
physician director services at the two dialysis centers acquired by the Company
pursuant to a physician director agreement with the Company.  Nephrology
Associates, P.A. and the Selling Stockholders have also entered into certain
covenants not to compete with the Company that, for a specified period following
the acquisition of the Florida Companies by the Company, restrict each of the
Selling Stockholders from soliciting clients, employees or contractors of
certain of the acquired dialysis centers, from disclosing information relating
to the operations of certain of the acquired dialysis centers, and from any
involvement in the provision of dialysis services in specified geographic areas
surrounding the respective acquired dialysis centers.

     Pursuant to each of two separate Agreements and Plans of Merger dated
as of July 23, 1996 among the Company, a subsidiary of the Company, the Selling
Stockholders and the Florida Companies (collectively, the "Florida Merger
Agreements"), the Company granted the Selling Stockholders certain registration
rights with respect to the Shares.  The Company has agreed to use reasonable and
diligent efforts to register the Shares within 75 days after July 23, 1996 on a
Form S-3 registration statement in a manner that will constitute a "shelf"
registration for purposes of Rule 415 under the Securities Act of 1933.  The
Registration Statement is being filed by the Company in order to register the
Shares and fulfill the foregoing obligation of the Company.

     Additional information as to the Selling Stockholders and their beneficial
ownership of the Company's Common Stock is set forth below. Except as otherwise
indicated, each Selling Stockholder has sole investment and voting power with
respect to the shares listed below.

     Pledgees, donees or transferees of or other successors in interest to the
Selling Stockholders will be identified in a supplement to this Prospectus. If
the number of shares of Common Stock transferred is material, the new holders of
the shares transferred will also be identified in a post-effective amendment to
the Registration Statement.

                              PLAN OF DISTRIBUTION

     The Company has been advised that the distribution of the Shares by the
Selling Stockholders, or by pledgees, donees or transferees of or other
successors in interest to the Selling Stockholders, may be effected from time
to time in one or more transactions (which may involve block transactions) on
the New York Stock Exchange or such other exchange or market in which the Common
Stock may from time to time be trading, in negotiated transactions or in a
combination of any such transactions. Such transactions may be effected by the
Selling Stockholders at market prices prevailing at the time of sale, at prices
related to such prevailing market prices, at negotiat-

                                       9
<PAGE>
 
ed prices or at fixed prices.  The Selling Stockholders may effect such
transactions by selling Shares to or through broker-dealers, including purchases
by a broker-dealer as principal and resale by such broker-dealer for its account
pursuant to this Prospectus.  Such broker-dealers will receive compensation in
the form of discounts or commissions from the Selling Stockholders and may
receive commissions from the purchasers of Shares for whom such broker-dealers
may act as agents (which discounts or commissions from the Selling Stockholders
or such purchasers, if in excess of those customary for the types of
transactions involved, will be disclosed in a supplemental prospectus).

     Any broker-dealer that participates with the Selling Stockholders in the
distribution of Common Stock may be deemed to be an "underwriter" within the
meaning of the Securities Act of 1933, and any commissions or discounts received
by such broker-dealer and any profit on the resale of Shares by such broker-
dealer may be deemed to be underwriting discounts and commissions under the
Securities Act of 1933.

     Under the terms of the Florida Merger Agreements, the respective costs and
expenses of the registration of the Shares, except for underwriting or selling
discounts or commissions, will be paid by the Company. These costs and expenses
borne by the Company will include, without limitation, all registration and
filing fees, printing expenses and costs of special audits incident to or
required by the registration of the Shares.

                                USE OF PROCEEDS

     The Company will not receive any of the proceeds from the sale of the
Shares offered hereunder by the Selling Stockholders.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the General Corporation Law of the State of Delaware
empowers a Delaware corporation to indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon plea of nolo contendere or its equivalent, does not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

     In the case of an action or suit by or in the right of the corporation to
procure a judgment in its favor, Section 145 empowers a corporation to indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by reason of the fact that he is
or was acting in any of the capacities set forth above against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, except that indemnifica tion is not permitted
in respect of any claim, issue or matter as to which such person is adjudged
<PAGE>
 
to be liable to the corporation unless and only to the extent that the Court of
Chancery of the State of Delaware or the court in which such action or suit was
brought determines upon application that, despite the adjudication of liability
but in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses which the Court of Chancery
or such other court deems proper.

     Section 145 further provides: that a Delaware corporation is required to
indemnify a director, officer, employee or agent against expenses (including
attorneys' fees) actually and reasonably incurred by him in defense of any
action, suit or proceeding referred to above or in defense of any claim, issue
or matter therein to the extent that such person has been successful on the
merits or otherwise; that the indemnification provided for by Section 145 shall
not be deemed exclusive of any other rights to which the indemnified party may
be entitled; that the indemnification provided for by Section 145 shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of such person's heirs, executors and administrators; and empowers the
corporation to purchase and maintain insurance on behalf of any person who is or
was a director, officer, employee or agent of the corporation against any
liability asserted against him and incurred by him in any such capacity or
arising out of his status as such, whether or not the corporation would have the
power to indemnify him against such liability under Section 145. A Delaware
corporation may provide indemnification only as authorized in the specific case
upon a determination that indemnification of the director, officer, employee or
agent is proper in the circumstances because he has met the applicable standard
of conduct. Such determination is to be made (i) by the board of directors by a
majority vote of a quorum consisting of directors who were not parties to such
action, suit or proceeding, or (ii) if such a quorum is not obtainable, or, even
if obtainable a quorum of disinterested directors so directs, by independent
legal counsel in a written opinion or (iii) by the stockholders.

     Article Eighth of the Company's Restated Certificate of Incorporation
provides for indemnification of directors and officers of the Company to the
fullest extent permitted by the General Corporation Law of the State of
Delaware, as presently or hereafter in effect.

     The Company provides liability insurance for each director and officer for
certain losses arising from claims or charges made against them while acting in
their capacities as directors or officers of the Company up to an aggregate of
$5,000,000 inclusive of defense costs, expenses and charges.

     Additionally, Article Seventh of the Company's Restated Certificate of
Incorporation limits the liability of the Company's directors to the fullest
extent permitted by Section 102(b)(7) of the General Corporation Law of the
State of Delaware, as the same may be amended and supplemented.  Section
102(b)(7) permits the certificate of incorporation of a Delaware corporation to
include a provision eliminating or limiting the personal liability of a director
of a corporation to the corporation or its stockholders for monetary damages for
breach of his fiduciary duty as a director; provided, however, that the
provision may not eliminate or limit the liability of a director for (i) any
breach of the director's duty of loyalty to the corporation or its stockholders;
(ii) acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law; (iii) the unlawful payment of dividends or
unlawful purchase or redemption of
<PAGE>
 
stock under Section 174 of the General Corporation Law of the State of Delaware;
or (iv) any transaction from which the director derived an improper personal
benefit.

ITEM 17.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes:

     (a)  to file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

          (i)  to include any prospectus required by Section 10(a)(3) of the
Securities Act;

         (ii)  to reflect in the prospectus any facts or events arising after
the effective date of this Registration Statement (or the most recent post-
effective amendment hereto) which individually or in the aggregate, represent a
fundamental change in the information set forth in this Registration Statement;
and

        (iii)  to include any material information with respect to the plan of
distribution not previously disclosed in this Registration Statement or any
material change to such information in this Registration Statement;

provided, however, that the undertakings set forth in paragraphs (i) and (ii)
above shall not apply if the information required to be included in a post-
effective amendment by those paragraphs is contained in periodic reports filed
by the registrant pursuant to Section 13 or 15(d) of the Exchange Act that are
incorporated by reference in this Registration Statement;

     (b)  that, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof; and

     (c)  to remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     The undersigned registrant hereby further undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933 and is, therefore, unenforceable.  In
the event that a claim for indemnification against such liabilities (other than
the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of any

officer or controlling person in connection with the securities being
registered, the registrant will,  unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act of 1933 and will be
governed by the final adjudication of such issue.

     The undersigned registrant hereby undertakes that:

     (1)  For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act of 1933 shall be deemed to be part of this registration
statement as of the time it was declared effective.

     (2)  For the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

(collectively, the "Financial Statements"):

               (i)  the unaudited balance sheet of PCAKC as of December 31, 1995
(the "Unaudited Balance Sheet"), and the related statements of operations, and
stockholders' equity for the year ended December 31, 1995; and

              (ii)  the unaudited balance sheets and income statements of PCAKC
as of December 31, 1993, 1994 and 1995 and the six month period ended June 30,

1995.

     Each of the Financial Statements has been prepared, to the extent
applicable, substantially in accordance with generally accepted accounting
principles applied on a consistent basis both as to classification of items and
amounts (except as may be indicated therein, excluding any notes thereto,
excluding accrued benefits and taxes, and except that management has elected to
omit substantially all of the disclosures and statements of retained earnings
and cash flows required by generally accepted accounting principles); and fairly
presents the financial position of PCAKC for the periods then ended (subject, in
the case of unaudited interim financial statements, to normal year-end
adjustments, which adjustments will not be material in amount or in effect).
Except as may be set forth in the Financial Statements, all of the revenues and
expenses of PCAKC reflected in the Financial Statements were derived or incurred

Financial Statements accurately and fairly reflect, in reasonable detail, the

applied on a consistent basis.  Except as set forth in Schedule 3.01(g), all
accounts, notes and other receivables of PCAKC as reflected in the Financial
Statements as of June 30, 1996, are valid and enforceable, and are not subject
to any valid defense, set off, counterclaim or claim for returns or refunds, and
are collectible substantially in full in accordance with their terms in the
ordinary course of business of PCAKC, except to the extent of any reserves
therefor reflected on the Financial Statements or taken in the ordinary course
of business consistent with past practice that in the aggregate will not a have
material adverse effect upon the financial condition, results of operation,
business,

PCAKC.  All amounts previously collected by PCAKC in respect of accounts, notes
and other receivables of PCAKC are not subject to any valid defense, set off,
counterclaim or claim for returns or refunds, except for the right of the
Medicare and Medicaid programs to reopen cost reports, adjust open cost reports
and claim refunds against other amounts payable, in which cases PCAKC has the
unrestricted right to pursue all available appeals of any such reopening,
adjustment or claim, or as reflected in the Financial Statements.

the said leases to which it is a party and has not received any notice of any
breach of its obligations under any covenants, agreements, statutory

best knowledge of the Individuals and PCAKC, complaints to, or by, any
government agency have been filed or are pending with respect to any Employee
Plan.

               (vi)  No Employee Plan, PCAKC and none of PCAKC's ERISA
Affiliates, or any "party in interest" or "disqualified person" (as such terms
are defined in Section 3 of ERISA, and Section 4975 of the Code) with respect to
any Employee Plan has taken any action (including the making of any investment),
or failed to take any action, that could subject any of them or any other person
to any liability for any tax or for breach of fiduciary duty with respect to or
in connection with any Employee Plan.

               (vii)  No Employee Plan, administrator or fiduciary of any
Employee Plan, or PCAKC has any liability under any provision of any applicable
law by reason of any communication or failure to communicate with respect to or
in connection with any Employee Plan, or any filing or failure to file with any
governmental entity.

               (viii) No Employee Plan, administrator or fiduciary of any
Employee Plan, none of PCAKC and none of PCAKC's ERISA Affiliates has any
liability to any plan participant, beneficiary or other person under any
provision of any applicable law by reason of any payment of benefits or other
amounts or failure to pay benefits or any other amounts, or by reason of any
credit or failure to give credit for any benefits or rights (such as, but not
limited to, vesting rights) with respect to benefits under or in connection with
any Employee Plan, other than benefit claims in the normal administration of
each Employee Plan. PCAKC is not delinquent or in arrears on any amounts owed
to, or with respect to any contributions under, any Employee Plan.
<PAGE>
 
               (ix) No person is a participant in, or eligible for participation
(without regard to age or service) in, any Employee Plan who is not a present or
former employee of PCAKC or a PCAKC ERISA Affiliate or a beneficiary of such an
employee.

               (x) None of the Employee Plans provides for continuing accrual of
benefits or coverage for any participant or beneficiary of a participant after
such participant's termination of employment with PCAKC or one of PCAKC's ERISA
Affiliates except as mandated by Section 4980B of the Code and Sections 601 et.
seq. of ERISA.

               (xi) Each Employee Plan and all amendments thereto intended to
qualify under Section 401(a) of the Code has been determined by the Internal
Revenue Service to so qualify, and the trusts created thereunder have been
determined to be exempt from tax under the provisions of Section 501(a) of the
Code, and copies of all determination letters with respect to each such Employee
Plan have been previously delivered by PCAKC to RTC, and nothing has since
occurred, or will occur prior to the Closing Date, which might cause the loss of
such qualification or exemption, no such Employee Plan has been operated in a
manner which would cause it to be disqualified in operation, and all such
Employee Plans have been administered in material compliance with and consistent
with all applicable requirements of the Code and ERISA, including, without
limitation, all reporting and disclosure requirements.

               (xii)  Nothing expressed or implied herein shall confer upon any
past or present employee of PCAKC, his or her representatives, beneficiaries,
successors and assigns, nor upon any collective bargaining agent, any rights or
remedies of any nature, including, without limitation, any rights to employment
or continued employment with PCAKC, RTC, the RTC Subsidiary or any successor or
affiliate thereto.

               (xiii) PCAKC has materially complied with the applicable
requirements of Section 4980B of the Code and Sections 601 et. seq. of ERISA.

          (aa) Cost Reports. All of the Medicare and Medicaid cost reports for
               ------------                                                   
the years ended December 31, 1992, 1993, 1994 and 1995 filed with respect to
each of the Facilities have previously been made available for review by PCAKC
to RTC and the RTC Subsidiary (collectively, the "Cost Reports"), and are true
and correct in all material respects and present fairly the cost of PCAKC's
operations at the relevant health care facility for the respective periods then
ended in substantial conformity with state and federal law.  PCAKC has filed all
cost reports required to have been filed for Medicare, Medicaid and, where
applicable, Blue Cross.
<PAGE>
 
          (bb) Licenses and Certification.  Schedule 3.01(bb) sets forth a
               --------------------------   -----------------             
complete list of all material licenses, certifications, accreditations,
consents, permits, approvals and certificates of need including, without
limitation, all Medicare, Medicaid and state health care facility licenses,
permits, certifications and governmental approvals that are necessary for, or
held and used in connection with the operation of each Facility owned, leased or
operated by PCAKC specifying with respect to each such license, permit,
certification and governmental approval the location and size of each part of
the applicable Facility so licensed or certified.  Each Facility is certified by
the appropriate state and federal authorities for the applicable Medicare and
Medicaid program, and such Facility is licensed to operate under the laws of the
state in which it is located, and all licenses, permits, certifications and
governmental approvals that are materially necessary to operate such Facility
are valid, current and in good standing.  None of the Facilities has incurred or
committed for expenditures requiring certificates of need but for which
certificates of need have not been duly obtained.  Attached to Schedule 3.01(bb)
                                                               -----------------
is a true and correct copy of all governmental licenses, permits and
certificates of need with respect to each Facility.

          (cc) Reimbursement Claims.  PCAKC has not made any claim for
               --------------------                                   
reimbursement under Medicare, Medicaid or any other payor programs without a
substantial basis for such claim other than billing errors occurring in the
ordinary course of business which billing errors have not had and will not have
a Material Adverse Effect on PCAKC or RTC Subsidiary.  PCAKC has not received
any notice that any Medicare, Medicaid or any other payor programs have any
claims against it that could result in a net offset against past or future
reimbursement.  PCAKC has no liability for any overpayment, refund,  discount or
adjustment ("Overpayment") in connection with Medicare, Medicaid or any other
reimbursement program or third party payer, except Overpayments customary in the
business.  No reimbursement program or payer has made or threatened any claim
for any Overpayment.  No Facility has ever claimed or received from the Medicare
program reimbursement for bad debts.  To the best knowledge of PCAKC and the
Individuals, within the last five years, none of the employees of PCAKC (while
acting in the capacity of an employee of PCAKC) has committed a violation of
the Medicare and Medicaid fraud and abuse provisions of the Social Security Act
or the Civil Monetary Penalties Law of the Social Security Act.

          (dd) Access to Books and Records.  All contracts of PCAKC with a value
               ---------------------------                                      
or cost of $10,000 or more over a twelve-month period entered into or renewed
since December 5, 1980, provide, or at the Effective Time of the Merger will
provide, to the extent required by law in conformity with Section 2 of the
Omnibus Reconciliation Act of 1980, P.L. 96499, for access to books and records
of subcontractors of Medicare providers by the
<PAGE>
 
Secretary of the Department of Health and Human Services.

          (ee) Inspection/Incident Reports.  (i) PCAKC has previously made
               ---------------------------                                
available for review by to RTC and the RTC Subsidiary true and complete copies
of all inspection/incident reports received since December 31, 1992 from the
state departments of health or other accreditation body of each state in which
PCAKC operates a health care facility.  PCAKC does not have any knowledge of any
change in any of the Facilities since the date of such reports that would make
any such reports inaccurate as of the date hereof.

               (ii)  PCAKC has not received any notice of any claim, requirement
or demand of any Governmental Authority, accreditation body, third party payor
or any insurance body having or claiming any licensing, certifying, supervising,
evaluating or accrediting authority over any health care or dialysis facility
owned, leased or operated by PCAKC to rework or redesign such facility, its
professional staff or its professional services, procedures or practices in any
respect or to provide additional furniture, fixtures, equipment or inventory so
as to make such facility conform to or comply with any applicable legal
requirement.

          (ff) Medicare/Medicaid Participation/Accreditation.  All of the
               ---------------------------------------------             
Facilities have a current and valid provider contract with the Medicare and
Medicaid programs, if required, as an ESRD facility providing the ESRD services
indicated on the Patient List, are in  substantial compliance with the
conditions of participation of such programs.  PCAKC has not received notice
from either the Medicare or Medicaid program of any pending or threatened
investigations or surveys, and PCAKC does not have any reason to believe that
any such investigations or surveys are pending, threatened or imminent.  PCAKC
has made available for review by RTC and the RTC Subsidiary complete and correct
copies of all surveys, reports or deficiency notices concerning the Facilities
by the Medicare program, the state survey agency, the Medicaid Program or the
respective state's kidney disease program.  The Medicare certification of each
Facility is in full force and effect, and (i) no violation of the condition and
standards of coverage, participation or certification exists, and (ii) no event
or circumstances exist (other than failure to perform an obligation not yet due)
which with the giving of notice or passage of time would constitute a violation.

               (ii)  Schedule 3.01(gg) sets forth a true and complete list of 
                     -----------------          
the rates currently charged for all services provided by PCAKC, and to PCAKC's
knowledge all of which rates do not exceed the maximum allowable rate, if any,
imposed by any applicable law or regulation.  PCAKC does not have any rate
appeal currently pending before any Governmental Authority or any administrator
of any third party payor program or referral
<PAGE>
 
source.

          (gg) Utilization Reviews.  The most recent utilization reviews
               -------------------                                      
relating to the Facilities by all applicable third party payors, accreditation
bodies and Governmental Authorities and reviews or scrutiny by any managed care
or utilization review companies have not had an adverse impact on the
utilization of programs at any such Facility.  No claims or assertions have been
made in any utilization review in possession of PCAKC or to which PCAKC has
access that any of the practices or procedures used at any such Facility are
improper or inappropriate.

          (hh) Operating Constraints.  There are no government contracts,
               ---------------------                                     
government permits or applicable legal requirements that require that a
percentage of slots or stations in any programs at any of the Facilities be
reserved for Medicaid or Medicare eligible patients or that any such facility
provide a certain amount of welfare, free or charity care or discontinued or
government-assisted patient care.

          (ii) Occupational Safety and Health.   PCAKC is in compliance with the
               ------------------------------                                   
applicable federal, state and local laws relating to occupational safety and
health, including, without limitation, the OSHA Bloodborne Pathogen Standard (29
C.F.R., 1910.130), and the general duty clause of the Occupational Safety and
Health Act (29 U.S.C.(S)654), other than violations which individually or
collectively would not have a Material Adverse Effect on PCAKC.

          (jj) RTC Common Stock Received; Lack of Registration Thereof;
               --------------------------------------------------------
Investment Intent.  Neither of the Individuals has any current plan or intention
- -----------------                                                               
to sell or otherwise dispose of more than fifty percent (50%) of the shares of
RTC Common Stock to be received by him upon consummation of the Merger.  The
Individuals understand that (i) the shares of RTC Common Stock to be issued to
the Individuals pursuant to the Merger will be issued under certain exemptions
from the registration provisions of the Securities Act of 1933 (the "Securities
Act"); (ii) the Individuals are acquiring the shares of RTC Common Stock without
being furnished any offering literature or prospectus; (iii) the issuance of the
shares of RTC Common Stock has not been examined by the Securities and Exchange
Commission or by any agency charged with the administration of the securities
laws of any state or other jurisdiction; and (iv) the Individuals have had the
opportunity to review certain materials, including financial information,
regarding RTC and the RTC Subsidiary and to ask questions of officers of the RTC
regarding RTC and the RTC Subsidiary.  Each of the Individuals represent and
warrant that he has such knowledge and experience in financial and business
matters that he is capable of evaluating the merits and risks of an investment
in the shares of RTC Common Stock and of making an informed investment decision
with respect thereto.  Each of the
<PAGE>
 
Individuals understand that RTC is relying on the truth and accuracy of the
representations, declarations and warranties made in this Section 3.01(kk) by
the Individuals in issuing the shares of RTC Common Stock without having first
registered the shares under the Securities Act or under the securities laws of
any state or other jurisdiction.  Each of the Individuals also confirms that (i)
he understands that there are substantial restrictions on the transferability of
the shares of RTC Common Stock he is to receive pursuant to the Merger and,
accordingly, it may not be possible for him to liquidate his investment in the
shares of RTC Common Stock in case of emergency and (ii) he is able to bear the
economic risk of his investment in the shares and to hold the shares for an
indefinite period of time.  The shares of RTC Common Stock are being acquired by
the Individuals in good faith solely for his own accounts, for investment
purposes only, and are not being acquired with a view to or for the resale,
distribution, subdivision or fractionalization thereof.  Neither of the
Individuals has any contract, undertaking, understanding, agreement or
arrangement, formal or informal, with any person to sell, transfer or pledge to
any person the shares of RTC Common Stock, or any part thereof, and neither of
the Individuals has any current plan to enter into any such contract,
undertaking, agreement or arrangement.  Each of the Individuals understands that
the legal consequences of the foregoing representations and warranties are that
he must bear the economic risk of his investment in the shares of the RTC Common
Stock for an indefinite period of time because the shares have not been
registered under the Securities Act.

          (kk) Sources of Revenue.  The sources of revenue of the business of
               ------------------                                            
each Facility consist of reimbursement for dialysis services, items and supplies
and related tests, studies, drugs, biologicals and blood provided by and through
the Facilities.  There are no other sources of revenue of the business of each
Facility other than immaterial revenues associated with management services
rendered on behalf of North Florida Artificial Kidney Center, Inc.

          (ll) Accounting Matters.  To the best knowledge of PCAKC and the
               ------------------                                        
Individuals on the basis of the representations and warranties set forth in that
certain pooling representation letter dated the date hereof addressed to Coopers
and Lybrand, L.L.P., the terms of which are hereby incorporated by reference,
neither the Individuals nor PCAKC have through the date of this Agreement taken
or agreed to take any action that (without giving effect to this Agreement, the
transactions contemplated hereby, or actions relating thereto, or any taken or
agreed to be taken by RTC or any of the RTC Subsidiary) would prevent RTC from
accounting for the business combination to be effected by the Merger as a
pooling of interests.

          (mm) Pooling of Interests Accounting.  The Individuals
               -------------------------------                  
<PAGE>
 
and PCAKC have consulted with Segers, Sowell & Stewart, P.A. as their
independent accountants, regarding the availability of pooling of interests
accounting for the transactions contemplated hereunder.  Such independent
accountants have reviewed the amounts and timing of salary, bonus and
distribution payments to the Individuals during 1994, 1995 and 1996 (as set
forth in Schedule 3.01(mm) hereto) and such independent accountants have not
         -----------------                                                  
stated to the Individuals any doubt that pooling of interests accounting will be
available with respect to the transactions contemplated hereunder.  The
Individuals and PCAKC do not presently believe that the condition precedent
contained in Section 6.01(c) hereof will not be capable of satisfaction or that
the Individuals and PCAKC will be required to take any action pursuant to
Section 4.01(c)(ii) hereof.   The provisions of this Section 3.01(mm) are hereby
qualified to the extent that such independent accounts have not performed audits
of PCAKC's financial statements and such independent accountants services on
behalf of their clients have been limited to compilations of financial
statements and tax return preparation.

          (nn) Material Misstatements or Omissions.  No representation or
               -----------------------------------                       
warranty by either the Individuals or PCAKC in this Agreement nor any documents,
exhibits, certificates or schedules furnished to RTC or the RTC Subsidiary
pursuant hereto, contains or will contain any untrue statement of a material
fact, or omits or will omit to state any material fact necessary to make the
statements or facts contained therein not misleading.  The copies of all
documents furnished to RTC or the RTC Subsidiary hereunder are true and complete
copies of the originals thereof in all material respects.

     SECTION 3.02. Representations and Warranties of RTC and  the RTC
                   --------------------------------------------------

- ----------
follows:
 
          (a)  Corporate Existence and Power.  Each of RTC and the RTC
               -----------------------------

standing under the laws of the State of Delaware and has all corporate power and
authority necessary to enable it to own, lease or otherwise hold its properties
and assets and to carry on its business as now conducted and proposed to be
conducted. RTC is duly qualified to do business as a foreign corporation and is
in good standing in each jurisdiction where the character of the property owned
or leased by it or the nature of its activities makes such qualification
necessary, except for those jurisdictions where the failure to be so qualified
would not, individually or in the aggregate, have a material adverse effect upon
the financial condition, results of operations, business, properties, assets,
operations or prospects of RTC or any of the RTC Subsidiary, individually or in
the aggregate (a "Material Adverse Effect on RTC"). RTC has previously made
available for inspection by the Individuals and
<PAGE>
 
to PCAKC true and complete copies of the certificates of incorporation and by-
laws of RTC and the RTC Subsidiary, as currently in effect.

          (b)  Corporate Authorization.  The execution, delivery and performance
               -----------------------                                          
by RTC and the RTC Subsidiary of this Agreement, and the consummation by RTC and
the RTC Subsidiary of the Merger and other transactions contemplated by this
Agreement, are within the corporate power and authority of RTC and the RTC
Subsidiary, respectively, and have been duly authorized by all necessary
corporate action.  This Agreement has been duly and validly authorized, executed
and delivered by RTC and the RTC Subsidiary and constitutes a valid and binding
obligation of RTC and the RTC Subsidiary enforceable against RTC and the RTC
Subsidiary in accordance with its terms.

          (c)  Governmental Authorization.  The execution, delivery and
               --------------------------                              
performance by RTC and the RTC Subsidiary of this Agreement, and the
consummation of the Merger and other transactions contemplated by this Agreement
by RTC and the RTC Subsidiary, do not and will not require any consent, approval
or action by or in respect of, or any declaration, filing or registration with,
any Governmental Authority, other than compliance with any applicable
requirements of the HSR Act, such ownership and disclosure forms and approvals
as may be required under federal and state health care and licensure laws and
regulations applicable to RTC, the RTC Subsidiary or any of their subsidiary,
approvals required under the health care and licensure laws and regulations of
the State of Florida, routine filings with the Secretary of State of the States
of Delaware and Florida, necessary to consummate the Merger, and compliance with
the applicable requirements of the Securities Act, the Securities Exchange Act
of 1934 (the "Exchange Act") and any applicable state securities and blue sky
laws in connection with the offer, sale and delivery of the shares of RTC Common
Stock to be issued in the Merger.

          (d)  Non-Contravention.  The execution, delivery and performance by 
               -----------------               
RTC and the RTC Subsidiary of this Agreement, and the consummation of the Merger
and other transactions contemplated by this Agreement by RTC and the RTC
Subsidiary, do not and will not, with or without the giving of notice, the lapse
of time or other: (i) contravene or conflict with the certificates of
incorporation or by-laws of RTC or any of the RTC Subsidiary, (ii) assuming
compliance with the matters referred to in Section 3.02(c), contravene or
conflict with or constitute a violation of any provision of any law, rule,
regulation, judgment, injunction, order or decree binding upon or applicable to
RTC or any of the RTC Subsidiary, (iii) require any consent, approval or other
action by any person, contravene or conflict with or constitute a violation of
or a default under, or give rise to any right of termination, cancellation or
acceleration of
<PAGE>
 
any right or obligation of RTC or any of the RTC Subsidiary or to a loss of any
benefit to which RTC or any of the RTC Subsidiary is entitled, under any
material provision of any material agreement, contract, indenture, any license,
franchise, permit or other similar authorization held by RTC or any of the RTC
Subsidiary, or any lease or other instrument binding upon RTC or any of the RTC
Subsidiary, assuming compliance with the matters referred to in Section 3.02
(c), except for the consent of First Union National Bank of North Carolina
("FUNB") required under the Fourth Amended and Restated Loan Agreement dated as
June 5, 1996, among, inter alia, RTC and FUNB or (iv) result in the creation or
                     ----- ----                                                
imposition of any Lien on any asset of RTC or any of the RTC Subsidiary.

          (e)  Finders' Fee.   There is no investment banker, broker, finder or
               ------------                                                    
other intermediary that has been retained by or is authorized to act on behalf
of RTC or any of the RTC Subsidiary who might be entitled to any fee or
commission upon consummation of the transactions contemplated by this Agreement.

          (f)  Litigation.  There is no action, suit, investigation or 
               ----------      
proceeding pending against, or to the knowledge of RTC and the RTC Subsidiary
threatened against, RTC or the RTC Subsidiary before any court or arbitrator or
any Governmental Authority that, if decided adversely to RTC or the RTC
Subsidiary would result in a Material Adverse Effect on RTC or the RTC
Subsidiary.

          (g)  Capitalization.  (i)  As of December 31, 1995, the authorized
               --------------                                               
capital stock of RTC consisted of (1) 5,000,000 shares of Preferred Stock, par
value $.01 per share, of which no shares were issued and outstanding or held in
the treasury of RTC, and (ii) 20,000,000 shares of RTC Common, of which
10,845,056 shares were issued and outstanding and 18,601 shares were held in the
treasury of RTC.  As of December 31, 1995, there were reserved for issuance
under RTC's stock option plans 842,111 shares of RTC Common Stock.  As of
December 31, 1995, there were outstanding options to purchase 631,199 shares of
RTC Common Stock under RTC's stock option plans.  Except as set forth above, as
of December 31, 1995, there were no outstanding (i) shares of capital stock or
other voting securities of RTC, (ii) securities of RTC convertible into or
exchangeable for shares of capital stock or voting securities of RTC or (iii)
(except for the right of the third party from whom RTC acquired certain assets
to require RTC to issue shares of its Common Stock in payment of a note)
options, warrants, exchange rights, subscription rights or other agreements,
commitments or rights to purchase or otherwise acquire from RTC, or agreements,
commitments or obligations of RTC to issue or sell, any capital stock, voting
securities  or securities convertible into or exchangeable for capital stock or
voting securities of RTC (items in clauses (i), (ii) and (iii) being referred to
collectively as the "RTC Securities").
<PAGE>
 
               (ii)  The authorized capital stock of the RTC Subsidiary consists
of 1,000 shares of Common Stock, par value $1.00 per share, 100 of which are
issued and outstanding and owned of record by RTC. All issued and outstanding
shares of Common Stock of the RTC Subsidiary are validly issued, fully paid and
nonassessable, and have not been issued in violation of any preemptive, first
refusal or other subscription rights of any stockholder of RTC, the RTC
Subsidiary or any other person.

          (h)  Reports and Financial Statements.  RTC has previously furnished 
               --------------------------------          
to PCAKC true and correct copies of (i) its Annual Report on Form 10-K for the
fiscal year ended December 31, 1995, (ii) its Quarterly Report on Form 10-Q for
the period ended March 31, 1996 and (iii) all other reports or registration
statements filed by it with the Commission under the Exchange Act since December
31, 1995 all in the form (including exhibits) so filed (collectively, the
"Reports").  As of their respective dates, the Reports did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.  Each of the audited
consolidated financial statements and unaudited interim financial statements
included in the Reports has been prepared in accordance with generally accepted
accounting principles applied on a consistent basis (except as may be indicated
therein or in the notes thereto) and fairly presents the financial position of
the entity or entities to which it relates as at its date or the results of
operations, stockholders' equity or cash flows, subject to normal year-end
adjustments and any other adjustments described therein, which adjustments will
not be material in amount or effect.

          (i)  Compliance with Laws; No Defaults.  (i)  Neither RTC nor any RTC
               ---------------------------------                               
Subsidiary is in violation of, and since December 31, 1995 has not violated, any
applicable provisions of any laws, statutes, ordinances or regulations, except
for violations that could not reasonably be expected to have, individually or in
the aggregate, a Material Adverse Effect on RTC.

               (ii)  Neither RTC nor any RTC Subsidiary is in default under, and
no condition exists that with notice or lapse of time or both would constitute a
default under, (A) any mortgage, loan agreement, indenture or evidence of
indebtedness for borrowed money to which RTC or any RTC Subsidiary is a party or
by which any of their assets is bound, which defaults or potential defaults,
individually or in the aggregate, have had, or could reasonably be expected to
have, a Material Adverse Effect on RTC or (B) any judgment, order or injunction
of any court, arbitrator or Governmental Authority.

          (j)  Pooling of Interests Accounting.  RTC has consulted with 
               -------------------------------           
Coopers & Lybrand, L.L.P. as its independent
<PAGE>
 
auditors, regarding the availability of pooling of interests accounting for the
transactions contemplated hereunder.  Such auditors have reviewed the amounts
and timing of salary, bonus and distribution payments to the Individuals during
1994, 1995 and 1996 (as set forth in Schedule 3.01(mm) hereto) and such auditors
                                     -----------------                          
have not stated to RTC any material doubt that pooling of interests accounting
will be available with respect to the transactions contemplated hereunder.  RTC
does not presently believe that the condition precedent contained in Section
6.01(c) hereof will not be capable of satisfaction or that the Individuals will
be required to take any action pursuant to Section 4.01(d)(ii) hereof.

          (k)  Issuance of the Total Shares.  The issuance and delivery by RTC 
               ----------------------------        
of the Total Shares in connection with the Merger and this Agreement have been
duly and validly authorized by all necessary corporate action on the part of
RTC. The Total Shares of RTC Common Stock to be issued in connection with the
Merger and this Agreement, when issued in accordance with the terms of this
Agreement, will be validly issues, fully paid and nonassessable.

          (l)  Absence of Certain Changes.  Except as disclosed in the Reports
               --------------------------                                     
filed with the SEC prior to the date hereof, since December 31, 1995, RTC has
conducted its business only in the ordinary course of such business and there
has not been (i) any Material Adverse Effect on RTC; or (ii) any change in its
accounting principles, practices or methods.

          (m)  Material Misstatements or Omissions.  No representation or
               -----------------------------------                       
warranties by RTC in this Agreement nor any Reports, documents, exhibits,
certificates or schedules furnished to PCAKC or the Individuals pursuant hereto,
contains or will contain any untrue statement of a material fact, or omits or
will omit to state any material fact necessary to make the statements or facts
contained therein not misleading.  The copies of all documents furnished to
PCAKC hereunder are true and complete copies of the originals thereof in all
material respects.

          (n)  Reimbursement Claims.  RTC has not made any material claim for
               --------------------                                          
reimbursement under Medicare, Medicaid or any other payor programs without a
substantial basis for such claim other than billing errors occurring in the
ordinary course of business which billing errors have not had and will not have
a Material Adverse Effect on RTC.  RTC has no liability for any overpayment,
refund,  discount or adjustment ("Overpayment") in connection with Medicare,
Medicaid or any other reimbursement program or third party payer, except
Overpayments customary in the business.  No reimbursement program or payer has
made or threatened any claim  for any Overpayment which claim if determined
adversely to RTC would have a Material Adverse Effect on RTC.  To the best
knowledge of RTC, within the last five
<PAGE>
 
years, none of the employees of RTC (while acting in the capacity of an employee
of RTC) ) has committed a violation of the Medicare and Medicaid fraud and abuse
provisions of the Social Security Act or the Civil Monetary Penalties Law of the
Social Security Act.

          as a pooling of interests or from treating the Merger as a
          "reorganization" under Section 368(a) of the Code; or

                    (xii)  authorize any of, or commit or agree to take any of,

directly or indirectly, through any officer, director, employee, representative

Subsidiary each hereby agrees (i) not to take any action that would adversely
affect the ability of RTC to treat the Merger as a pooling of interests, and

any past actions which would adversely affect the ability of RTC to treat the
Merger as a pooling of interests in accordance with generally accepted
accounting principles consistently applied and all published rules, regulations
and policies of the Securities Exchange Commission in effect on the date hereof.

          (d)  Other Actions.  PCAKC on the one hand and RTC and the RTC

               ------------------- 
 
               (i)  Each of the Individuals understands and agrees that the RTC
Common Stock may be transferred by any holder thereof only pursuant to (A) a
public offering thereof registered under the Securities Act, (B) Rule 144 of the
Securities and Exchange Commission (the "Commission") (or any similar rule in
force at the time of such transfer) if such rule is available, or (C) any other
legally available means of transfer.

               (ii) In connection with the transfer of the RTC Common Stock, or
any part thereof, the holder thereof shall deliver written notice to RTC
describing in reasonable detail the transfer or proposed transfer, together with
an opinion of counsel that it is knowledgeable in securities law matters and
reasonably acceptable to RTC, to the effect that such transfer may be effected
without registration under the Securities Act and under applicable state
securities laws. In addition, if the holder of the securities to be transferred
delivers to RTC an opinion of counsel that no subsequent transfer of such RTC
Common Stock will require registration under the Securities Act or under
applicable state securities laws, RTC shall promptly upon such 
<PAGE>
 
contemplated transfer deliver new certificates for such RTC Common Stock that do
not bear the restrictive legend set forth in Section 5.01(b)(i) hereof.  If RTC
is not required to deliver new certificates for such RTC Common Stock not
bearing such legend, the holder thereof shall not transfer such RTC Common Stock
until the prospective transferee has confirmed to RTC in writing his or its
agreement to be bound by the conditions contained in this Section 5.01(a).

          (b)  Restrictive Legends.  The RTC Common Stock and any shares of
               -------------------

                    THE SECURITIES ACT OF 1933 OR THE SECURITIES LAWS OF ANY
                    STATE.  THESE SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN
                    THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM
                    UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS.

               (ii) THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
                    TO RESTRICTIONS ON TRANSFERABILITY SET FORTH IN SECTIONS
                    5.01 AND 5.06 OF THE AGREEMENT AND PLAN OF MERGER, DATED AS

file all reports required to be filed by it under the Exchange Act and the rules
and regulations thereunder and shall take such further action as any holder of
RTC Common Stock may reasonably request, all to the extent required to enable
any such holder to sell the RTC Common Stock pursuant to Rule 144 under the
Securities Act (as such rule may be amended from time to time) or any similar
rule or regulation then in force.  Upon written request, RTC shall deliver to
any holder of any RTC Common Stock a written statement as to whether RTC is in
compliance with such requirements.
<PAGE>
 
          (d)  S-3 Registration Rights.
               ----------------------- 

               (i)  Registration Rights.  RTC will register the shares of RTC

Common Stock issued to the Individuals in the Merger within the seventy (75)
days following the Effective Time of the Merger on Form S-3 under the Securities
Act, or any successor to such form in a manner that will, upon being declared
effective, constitute a "shelf" registration for purposes of Rule 415 under the
Securities Act, pursuant to which the Shareholder may sell the shares of RTC
Common Stock received by him in the Merger, from time to time and in such
amounts as Shareholder may hereafter determine, all in a manner consistent with
the provisions of 5.07(a) hereof, Exhibit D hereto and all applicable provisions
of the Securities Act and the Exchange Act. RTC will use its best efforts to
have the Form S-3 declared effective.

               (ii) Registration Procedure.  With respect to registration under
                    ----------------------                                     
Section 5.01(d)(i), RTC shall prepare and file such amendments, post-effective
amendments and periodic reports under the Exchange Act as may be necessary to
keep such registration statement continuously effective until the second
anniversary of the Closing Date.  Notwithstanding the foregoing, RTC shall not
be required to update, pursuant to this Section 5.01(d), any document during a
period when RTC shall, in good faith and using reasonable business judgment,
believe that the premature disclosure of any event or information would have a
Material Adverse Effect on RTC or its prospects.  The Individuals hereby agree,
that upon receipt of notice from RTC of the happening of any occurrence
described in the preceding sentence, each of the Individuals shall forthwith
discontinue disposition of the shares of RTC Common Stock received by him in the
Merger pursuant to such registration statement until the Individuals's receipt
of the copies of the supplemented or amended prospectus, and, if so directed by
RTC, each of the Individuals shall deliver to RTC all copies in his possession,

prospectus covering such RTC Common Stock current at the time of receipt of such
notice.

without limitation, all registration and filing fees, printing expenses, and
costs of special audits incident to or required by such registration) or the
transactions contemplated herein.

          (e)  Further Actions by the Individuals.  Each of the Individuals
               ----------------------------------                          
agrees to furnish to RTC and the RTC Subsidiary such
<PAGE>
 
information and execute such documents regarding the shares of RTC Common Stock
received by him in the Merger and the intended method of disposition thereof as
RTC shall reasonably request and as shall be required in connection with the
actions to be taken by RTC under the provisions of Section 5.01(d) above.  Each
of the Individuals further agrees to comply with all provisions of the
Securities Act and the Exchange Act and all applicable state securities law.

     SECTION 5.02.  Best Efforts; Notification.  (a)  Upon the terms and subject
                    --------------------------                                  
to the conditions set forth in this Agreement, each of the parties agrees to use
its best efforts to take, or cause to be taken, all actions, and to do, or cause
to be done, and to assist and cooperate with the other parties in doing, all
things necessary, proper or advisable to consummate and make effective, in the
most expeditious manner practicable, the  Merger and the other transactions
contemplated by this Agreement, including (i) the obtaining of all necessary
actions or nonactions, waivers, consents and approvals from Governmental
Authorities and the making of all necessary registrations and filings (including
filings with Governmental Authorities, if any) and the taking of all reasonable
steps as may be necessary to obtain an approval or waiver from, or to avoid an
action or proceeding by any Governmental Authority, (ii) the obtaining of all
necessary consents, approvals or waivers from third parties and (iii) the
execution and delivery of any additional instruments necessary to consummate the
transactions contemplated by, and to fully carry out the purposes of this
Agreement.

          (b)  PCAKC and the Individuals shall give prompt notice to RTC and the
RTC Subsidiary, and RTC and the RTC Subsidiary shall give prompt notice to the
Individuals and PCAKC, of (i) any representation or warranty made by it
contained in this Agreement that is qualified as to materiality becoming untrue
or inaccurate in any respect or any such representation or warranty that is not
so qualified becoming untrue or inaccurate in any material respect or (ii) the
failure by it to comply with or satisfy in any material respect any covenant,
condition or agreement to be complied with or satisfied by it under this
Agreement; provided, however, that no such notification shall affect the
           -----------------                                            
representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under this Agreement.

     SECTION 5.03 (a).  Indemnification by PCAKC and Individuals.  (i) PCAKC and
                        ----------------------------------------                
the Individuals, jointly and severally, agree to indemnify, defend and hold
harmless RTC and the RTC Subsidiary, at any time after the Closing from and
against all liabilities, losses, claims, costs or damages whatsoever, including
expenses and reasonable fees of legal counsel (collectively, "RTC Indemnified
Losses"), arising out of or from or based upon:
<PAGE>
 
     (A)  the inaccuracy of any representation or warranty contained herein made
by PCAKC or the Individuals;

     (B)  the non-performance or breach by PCAKC or the Individuals of any
covenant, agreement or obligation to be performed by PCAKC or the Individuals
hereunder; or

     (C)  any contract or arrangement entered into prior to the Closing Date
between PCAKC and the Individuals that did not or may not have satisfied the
provisions of federal and state laws and regulations relating to restrictions on
physician referrals or claims for payment under the Medicare, Medicaid or other
programs for the furnishing of health services, including, but not limited to
the provisions of the Omnibus Budget Reconciliation Act of 1993 which failure
could have a Material Adverse Effect on PCAKC.

     (ii) The indemnification for any RTC Indemnified Losses pursuant to this
Section 5.03(a) shall be calculated net of any net tax benefit (giving effect to
the payment of any additional taxes that may be incurred by RTC or the RTC
Subsidiary from treatment of such indemnification payments as taxable income or
gain to RTC or the RTC Subsidiary) to RTC or the RTC Subsidiary (utilized by RTC
or the RTC Subsidiary against income of RTC or the RTC Subsidiary in the year
that RTC or the RTC Subsidiary deducts such liability, loss, claim, cost or
expense in its income tax returns, regardless of whether RTC or the RTC
Subsidiary receives any tax benefits in any other year by reason of any net
operating loss or other available income tax carryforwards or carrybacks),
resulting from such RTC Indemnified Losses, provided that the amount of any tax
liabilities arising from the payment of such indemnification shall not increase
the amount of the underlying claim.

     (iii)     Limitation on Liability.  PCAKC and the Individuals shall not be
               -----------------------                                         
liable under this Section 5.03(a) for RTC Indemnified Losses in the event that
RTC Indemnified Losses in the aggregate are less than $200,000.  If the
aggregate amount of RTC Indemnified Losses exceeds $200,000 then RTC and the RTC
Subsidiary may claim indemnification for the aggregate amount of RTC Indemnified
Losses less $200,000.  In no event shall the obligations of PCAKC and the
Individuals for RTC Indemnified Losses exceed $10,600,000.  In addition, the
individual joint and several liability of each Individual shall not exceed Five
Million Three Hundred Thousand Dollars ($5,300,000).

     (iv) Indemnification Payment in RTC Shares.  In the event that the
          -------------------------------------

     (b)  Indemnification by RTC.  (i) RTC agrees to indemnify, defend and hold
          ----------------------                                               
harmless PCAKC and the Individuals, at any time after the Closing from and

expenses and reasonable fees of legal counsel (collectively, "PCAKC Indemnified
Losses") arising out of or from or based upon:

     (A)  the inaccuracy of any representation or warranty contained herein made
by RTC or the RTC Subsidiary.

     (B)  the non-performance or breach by RTC or the RTC Subsidiary of any
covenant, agreement or obligation to be performed by RTC or the RTC Subsidiary
hereunder, or

     (C)  any and all liabilities, losses, claims, costs or damages whatsoever
relating to the Registration Statement on Form S-3 to be filed by RTC pursuant
to Section 5.01 of this Agreement (the "Registration Statement") or the failure
to so file such Form S-3 other than liabilities, losses, claims, costs or
damages resulting from (A) information provided in writing by or on behalf of
either of the Individuals or (B) the failure of either of the Individuals to
disclose to RTC any fact relating to either of the Individuals required to be
disclosed in the Registration Statement.

     (ii)  The indemnification for any PCAKC Indemnified Losses pursuant to this
Section 5.03(b) shall be calculated net of any net tax benefit (giving effect to
the payment of any additional taxes that may be incurred by PCAKC or the
Individuals from treatment of such indemnification payments as taxable income or
gain to PCAKC or the Individuals) to PCAKC or the Individuals (utilized by PCAKC
or the Individuals against income of PCAKC or the Individuals in the year that
PCAKC or such Individual deducts such liability, loss, claim, cost or expense in
its or his income tax returns, regardless of whether PCAKC or such Individuals
receive any tax benefits in any other year by reason of any net operating loss
or other available income tax carryforwards or carrybacks), resulting from such
PCAKC Indemnified Losses, provided that the amount of any tax liability arising
from the payment of such indemnification shall not increase the amount of the
underlying claim.

Losses in the aggregate are less than $200,000.  If the aggregate amount of
PCAKC Indemnified Losses exceeds $200,000 then PCAKC and the Individuals may
claim indemnification for the aggregate amount of PCAKC Indemnified Losses less
$200,000.  In no event shall the obligations of RTC for PCAKC Indemnified Losses
exceed $10,600,000.

     (c)  Conditions of Indemnification.
          ----------------------------- 
 
     (i)  Whenever any claim is made by any person not a party to this Agreement
with respect to any matter to which the indemnifications contained in this
Section 5.03 relate, the indemnified party (the "Indemnitee") shall notify the
indemnifying party (the "Indemnitor") in writing within twenty (20) days after
the Indemnitee has notice of the facts constituting the basis for such claim
(the "Notice of Claim").  Whenever any claim is made by one of the parties to
this Agreement with respect to any matter to which the indemnification contained
in this Section 5.03 relates, as soon as practicable after the Indemnitee
becomes aware of such claim, the Indemnitee shall send a Notice of Claim to the
Indemnitor.  The Notice of Claim shall specify all facts known to the Indemnitee
giving rise to such indemnification claim and the amount of an estimate of the
amount of the liability arising therefrom.  The Notice of Claim shall be given
in accordance with Section 8.03 hereto.

     (ii)   Each claim will be deemed approved by the Indemnitor, unless the
Indemnitor gives the Indemnitee written notice of disapproval within thirty (30)
days of receipt of such second Notice of Claim.  The parties shall undertake, in
good faith, to resolve any dispute with respect to any such claim which is so
disapproved; if the parties are unable to agree on such resolution within thirty
(30) days after the Indemnitee receives notice of disapproval from the
Indemnitor, the respective rights of the parties shall be determined by
arbitration in Panama City, Florida, in accordance with the rules of the
American Arbitration Association.  If the two parties cannot  jointly select a
single arbitrator to determine the matter, one arbitrator shall be chosen by
each party (or, if a party fails to make a choice, by the American Arbitration
Association on behalf of such party) and the two arbitrators so chosen will
select a third.  The decision of the single arbitrator jointly selected by the
parties, or, if three arbitrators are selected, the decision of any two of them,
will be final and binding upon the parties and the judgement of a court of
competent jurisdiction may be entered thereon.  Fees of the arbitrators and
costs of arbitration shall be borne by the parties in such manner as shall be
determined by the arbitrator or arbitrators.

     (iii)  If the facts giving rise to any such
<PAGE>
 
indemnification shall involve any actual, threatened or possible claim or demand
by any person against the Indemnitee, the Indemnitor shall be entitled to
contest or defend such claim at its expense and through counsel of its own
choosing if it gives written notice of its intention to assume the contest and
defense of such claim to the Indemnitee within thirty (30) days after receipt
of the Notice of Claim.  If the Indemnitor shall exercise such option, it shall
have control over such contest and defense and over the payment, settlement or
compromise of such claim, and the Indemnitee agrees to cooperate fully with the
Indemnitor and its attorneys with respect to such contest and defense.  If the
Indemnitor shall not exercise such option, the Indemnitee may, but shall not be
obligated to, assume the contest and defense of such claim.  Any payment or
settlement resulting from such contest, together with the total expenses
thereof, including but not limited to attorneys' fees, shall be binding upon the
Indemnitor and the Indemnitee.

     (d)  Actual Knowledge.  An Indemnitor shall not be liable under this 
          ----------------        
Section 5.03(a)(i)(A) for a loss resulting from any event relating to a breach
of any representation or warranty if the Indemnitor can establish that the
Indemnitee had actual knowledge on or before the Closing Date of such event.

     (e)  Personal Indemnification.  The Individuals, jointly and severally,
          ------------------------                                          
hereby agree to personally indemnify and hold harmless RTC and the RTC
Subsidiary from and against any and all Indemnified Losses arising out of events
occurring on or before the first anniversary of the Effective Time of the
Merger.

     (f)  Survival of Indemnification Obligations.

indemnification under Sections 5.03(a)(i)(A) and (B) hereof, the earlier of (1)

the report on the first audit of the combined operations of RTC and PCAKC; and
(B) in the case of indemnification under Sections 5.03(a)(i)(C) and
5.03(a)(i)(D) hereof, the expiration of the applicable statute of limitations
period.

          (ii) Notwithstanding anything herein to the contrary, the obligations
of RTC under this Section 5.03 shall survive the Effective Time of the Merger

consummated.

     SECTION 5.05.  Public Announcements.  RTC and the RTC Subsidiary, on the
                    --------------------                                     
one hand, and PCAKC and the Individuals, on the other hand, will consult with
each other before issuing, and provide each other the opportunity to review,
comment upon and concur with, any press release or other public statements with
respect to the transactions contemplated by this Agreement, including the
Merger, and shall not issue any such press release or make any such public
statement prior to such consultation, except as may be required by applicable
law, court process or by obligations pursuant to any listing agreement with any
national market system.  The parties agree that the initial press release to be
issued with respect to the transactions contemplated by this Agreement is set
forth in Exhibit A to this Agreement and that no other press release regarding
this transaction is contemplated.

     SECTION 5.06.  Affiliates and Certain Stockholders.  (a) Prior to the

Closing Date, the Individuals and PCAKC shall deliver to RTC and the RTC
Subsidiary a letter identifying all persons who are "affiliates" of the
Individuals and PCAKC, respectively, for purposes of applicable interpretations
regarding the pooling-of-interests method of accounting.  The Individuals and
PCAKC shall use their best efforts to cause each such person to deliver to RTC
and the RTC Subsidiary on or prior to the Closing Date a written agreement
substantially in the form attached as Exhibit B hereto.  If the Merger would
otherwise qualify for pooling-of-interests accounting treatment, shares of RTC
Common Stock issued to such affiliates of the Individuals or PCAKC in exchange
for shares of PCAKC Common Stock shall not be transferable until such time as
financial results covering at least thirty (30) days of combined operations of
RTC, the RTC Subsidiary and PCAKC have been published within the meaning of
Section 201-01 of the SEC's Codification of Financial Reporting Policies,
regardless of whether each such affiliate has provided the written agreement
referred to in this Section 5.06, except to the extent permitted by, and in
accordance with, Accounting Series Release 135 and Staff Accounting Bulletins 65
and 76.  Any shares of PCAKC Common Stock held by such affiliates shall not be
transferable, regardless of whether each such affiliate has provided the written
agreement referred to in this Section 5.06, if such transfer, either alone or in
the aggregate with other transfers by affiliates, would preclude RTC's ability
to account for the business combination to be effected by the  Merger as a
pooling of interests.  Neither the Individuals nor PCAKC shall register the
transfer of any certificate representing capital stock of PCAKC, unless such
transfer is made in compliance with the foregoing.  Except as provided in
Section 5.01 hereof, RTC
<PAGE>
 
shall not be required to maintain the effectiveness of any registration
statement under the Securities Act for the purposes of resale of the RTC Common
Stock by such affiliates and the certificates representing the RTC Common Stock
received by such affiliates in the Merger shall bear a customary legend
regarding applicable Securities Act restrictions and the provisions of this
Section 5.06.

          (b)  The Individuals shall deliver to RTC on the Closing Date a
letter, dated as of such date, identifying all persons who are, as of such date,
beneficial owners of five percent (5%) or more of the capital stock of PCAKC.
The Individuals shall cause each such person, including himself, to deliver to
counsel to RTC on the Closing Date a representation letter, in each case dated
as of such date and substantially in the form attached as Exhibit C hereto.

          (c)  Each of the Individuals agrees that he will hold, either directly
or indirectly, at least fifty-one percent (51%) of the shares of RTC Common
Stock received by him in the Merger for a period of at least one year from the
Closing Date and acknowledges that he presently intends to hold, either directly
or indirectly, at least fifty-one percent (51%) of the shares of RTC Common
Stock received by them in the Merger for at least two (2) years from the Closing
Date.

and substantially in the form of Exhibit E hereto, for the purpose of the
reliance of such counsel delivering the opinions described in Section 6.01(d).

least one historic business line of the PCAKC, or to use at least a significant
portion of its historic business assets in a business, in each case within the
meaning of Treas. Reg. Section 1.368-1(d) for at least 5 years.

     SECTION 5.09.  Tax-Free Reorganization.  RTC, RTC Subsidiary and the
                    -----------------------                              
Individuals shall each use their respective best efforts
                                            ------------
<PAGE>
 
to cause the Merger to be treated as a reorganization within the meaning of
Section 368 of the Code provided however such best effort shall not apply to RTC
for any actions taken by any third party including the Individuals which would
effect in any way the Merger being treated as an reorganization.  RTC Subsidiary

method of accounting to the accrual method of accounting shall be borne by RTC
Subsidiary.

hereto.  PCAKC employees will be entitled to all benefits offered to other

preserve and keep the records of PCAKC acquired by it pursuant to this Agreement
for a period of seven (7) years, or for any longer period as may be required by

     in Section 6.01, 6.02 or 6.03, as the case may be, to be satisfied if such

     Individuals and PCAKC;

          (b)  by either RTC or PCAKC:

                    (i) if the Merger shall not have been consummated on or
               before the date ninety (90) days following the date of this

               result of a willful and material breach of this Agreement by the
               party  seeking to terminate this Agreement; provided,  however,
                                                           ------------------

               condition set forth in Section 6.02(a) or (b) or Section 6.03(a)
               or (b), as applicable, and (B) cannot be or has not been cured

     this Agreement as provided in Section 7.01, this Agreement shall forthwith
     become void and have no effect, without any liability or obligation on the
     part of RTC, the RTC Subsidiary, the Individuals or PCAKC, other than the
     provisions of Section 7.02 and all of Article VIII and except to the extent
     that such termination results from the willful and material breach by a
     party of any of its representations, warranties, covenants or agreements
     set forth in this Agreement.

          (b)  Expenses.  Notwithstanding anything herein to the contrary, in
               --------                                                         
     the event this Agreement is terminated (i) due to a failure of the
     shareholders of any of the corporate parties hereto to approve this
     Agreement and the transactions contemplated hereby or (ii) by RTC or the
     RTC Subsidiary due to a Breach by the Individuals or PCAKC, or by the
     Individuals or PCAKC due to a Breach by RTC or the RTC Subsidiary, then the
     other party shall be entitled to reimbursement from the other, jointly and
     severally, within ten (10) days after written demand therefor for all fees
     and expenses incurred by such other party in connection with this Agreement
     and the transactions contemplated hereby.

          (c)  Specific Performance, Injunctive Relief and Other Remedies.  In
               ----------------------------------------------------------     
     the event (a) this Agreement is terminated (i) due to a failure of the
     shareholders of PCAKC to approve this Agreement and the transactions
     contemplated hereby or (ii) by RTC or the RTC Subsidiary due to a breach by
     the Individuals, and (b) PCAKC  is involved in a "Change of Control", as
     defined herein, within one (1) year after such termination and any
     preliminary contracts or discussions with any of the Individuals and or
     PCAKC or any representative thereof relative thereto occurred prior to the
     termination of this Agreement, then the Individuals and PCAKC acknowledge
     and agree that any intentional and material breach by them of the
     provisions of this Agreement will cause RTC and the RTC Subsidiary
     irreparable injury and damage, for which RTC and the RTC Subsidiary cannot
     be adequately compensated in damages.  Therefore, the Individuals and PCAKC
     expressly agree that RTC and the RTC Subsidiary shall, in addition to all
     other remedies legally available to them, be entitled to specific
     performance,

                                     -50-
<PAGE>
 
     preliminary and permanent injunctive relief and/or other equitable relief
     to prevent any anticipatory or continuing breach of this Agreement, or any
     part thereof, and to secure its enforcement and shall be entitled to the
     recovery of reasonable attorney's fees and costs in connection therewith.
     Nothing herein shall be construed as a waiver by RTC or the RTC Subsidiary
     of any right they may now have or hereafter acquire to monetary damages,
     including without limitation consequential damages and special damages, by
     reason of any injury to their property, business or business prospects or
     otherwise arising out of any wrongful act or omission of the Individuals
     and/or PCAKC hereunder.  The Individuals and PCAKC acknowledge that the
     provisions of this Section 7.02(c) are made as part of a contract for the
     sale of a business interest; the parties are of equal bargaining power; RTC
     and the RTC Subsidiary would not acquire the capital stock of PCAKC from
     the Individuals as the sole shareholders of PCAKC in exchange for shares of
     capital stock of RTC as provided in this Agreement except in consideration
     of the provisions of this Section 7.02(c); the restrictions contained
     herein are reasonable and necessary to protect the legitimate interests of
     RTC, the RTC Subsidiary and their Affiliates; and any violation of these
     restrictions would result in irreparable injury to RTC and its Affiliates
     not compensable by payment of monetary damages.  If any provision of this
     Section 7.02(c) shall be invalid or unenforceable, in whole or in part,
     then such provision shall be deemed to be modified or restricted to the
     extent and in the manner necessary to render the same valid and
     enforceable, or shall be deemed excised from this Section 7.02(c), as the
     case may require, and this Section 7.02(c) shall be construed and enforced
     to the maximum extent permitted by law as if such provision had been
     originally incorporated herein as so modified or restricted or as if such
     provision had not been originally incorporated herein, as the case may be.

     SECTION 7.03. Amendment.  This Agreement may be amended by  the parties at
                   ---------                                                   
any time; provided, however, there shall be made no amendment that by law
          --------  -------                                              
requires further approval by such stockholders of any of the parties hereto
without the further approval of the stockholders.  This Agreement may not be
amended except by an instrument in writing signed on behalf of each of the
parties.

     SECTION 7.04. Extension; Waiver.  At any time prior to the Effective Time
                   -----------------                                          
of the Merger, the parties may (a) extend the time for the performance of any of
the obligations or other acts of the other parties, (b) waive any inaccuracies
in the representations and warranties of the other parties contained in this
Agreement or in any document delivered pursuant to this Agreement, or (c)
subject to the proviso of Section 7.03, waive

                                     -51-
<PAGE>
 
compliance by the other parties with any of the agreements or conditions
contained in this Agreement.  Any agreement on the part of a party to any such
extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party.  The failure of any party to this Agreement to
assert any of its rights under this Agreement or otherwise shall not constitute
a waiver of such rights.

     SECTION 7.05. Procedure for Termination, Amendment,  Extension or Waiver.
                   ----------------------------------------------------------  
A termination of this Agreement pursuant to Section 7.01, an amendment of this
Agreement pursuant to Section 7.03 or an extension or waiver pursuant to Section
7.04 shall, in order to be effective, require in the case of RTC, the RTC
Subsidiary or PCAKC, action by its Board of Directors or the duly authorized
designee of its Board of Directors.

               ------------------------------------------------
              Constituent Corporations; Exchange of Certificates
              --------------------------------------------------

      SECTION 2.01. Effect on Capital Stock.  As of the  Effective Time
                    ------------------------                           
of the Merger, by virtue of the Merger and without any action on the part of the
holder of any shares of NFAKC Common Stock or any shares of capital stock of
the RTC Subsidiary:

          (a)  Capital Stock of Subsidiary.  Each issued and outstanding share 
               ---------------------------             
of capital stock of the RTC Subsidiary shall remain issued and outstanding.

          (b)  Cancellation of Treasury Stock.  Each share of NFAKC Common Stock
               ------------------------------                                   
that is owned by NFAKC or by any subsidiary (as defined in Section 8.03 hereof)
of NFAKC shall automatically be cancelled and retired and shall cease to exist,
and no RTC Common Stock or other consideration shall be delivered in exchange
therefor.

          (c)  Conversion of NFAKC Common Stock.   All of the issued and
               --------------------------------                         
outstanding shares of NFAKC Common Stock (other than shares to be cancelled in
accordance with Section 2.01(b)) shall be converted into the right to receive an
aggregate of the Total Shares (as defined below).  As of the Effective Time of

each holder of a certificate representing any such shares of NFAKC Common Stock
shall cease to
<PAGE>
 
have any rights with respect thereto, except the right to receive that number of
shares of RTC Common Stock to be issued in consideration therefor upon surrender
of such certificate in accordance with Section 2.02.  For purposes herein the
term "Total Shares" shall be deemed the number of shares of RTC Common Stock

Common Stock for the five (5) business days immediately prior to the Effective
Time of the Merger.

     SECTION 2.02.  Exchange of Certificates.   At the Closing, the
                    ------------------------                       
Individuals as the holders of one hundred percent (100%) of the outstanding
shares of NFAKC Common Stock shall deliver to the RTC Subsidiary the
certificates for cancellation that immediately prior to the Effective Time of
the Merger represented all of the outstanding shares of NFAKC Common Stock
(collectively, the "Certificates") duly endorsed for transfer by the
Individuals.  Upon delivery by the Individuals to the RTC Subsidiary of the
Certificates so endorsed and such other documents as may reasonably be required
by the RTC Subsidiary, the Individuals, as the sole holders of shares of NFAKC
Common Stock, shall be entitled to receive in exchange therefor a certificate
representing that number of shares, rounded to the nearest whole share, of RTC
Common Stock which such Individuals as such holders have the right to receive
pursuant to the provisions of this Article II, and each of the Certificates so
surrendered shall forthwith be cancelled.  As of the Effective Time of the
Merger, the RTC Subsidiary shall cause to be issued in the name of the
Individuals as the sole holder of shares of NFAKC Common Stock a certificate
representing the Total Shares in exchange for the Certificates.

delivered to RTC and the RTC Subsidiary the following financial statements
(collectively, the "Financial Statements"):

               (i)   the unaudited balance sheet of NFAKC as of December 31,
1995 (the "Unaudited Balance Sheet"), and the related statements of operations,
and stockholders' equity for the year ended December 31, 1995; and

               (ii)  the unaudited balance sheets and income statements of NFAKC
as of December 31, 1994 and 1995 and the six month period ended June 30, 1996
(collectively the "Unaudited Balance Sheets") and the related statements of
operations for the years then ended; and

               (iii) to the extent completed before the date hereof, a correct
and complete copy of HCFA Form 265, Renal Dialysis Facility Statistical Data,
for the Facilities listed on Schedule 3.01(j) for the year ended December 31,
                             ----------------     
1995.

     Each of the Financial Statements has been prepared, to the extent
applicable, substantially in accordance with generally accepted accounting
principles applied on a consistent basis both as to classification of items and
amounts (except as may be indicated therein, excluding any notes thereto,
excluding accrued benefits and taxes, and except that management has elected to
omit substantially all of the disclosures and statements of retained earnings
and cash flows required by generally accepted accounting principles); and fairly
presents the financial position of NFAKC for the periods then ended (subject, in
the case of unaudited interim financial statements, to normal year-end
adjustments, which adjustments will not be material in amount or in effect).
Except as may be set forth in the Financial Statements, all of the revenues and
expenses of NFAKC reflected in the Financial Statements were derived or incurred
in the ordinary course of business of NFAKC.  The account records underlying the
Financial Statements accurately and fairly reflect, in reasonable detail, the
transactions of NFAKC, and NFAKC's books of account have been maintained in
accordance with generally accepted accounting principles applied on a consistent
basis.  Except as set forth in Schedule 3.01(g), all accounts, notes and other
receivables of NFAKC as reflected in the Financial Statements as of June 30,
1996, are valid and enforceable, and are not subject to any valid defense, set
off, counterclaim or claim for returns or refunds, and are collectible
substantially in full in accordance with their terms in the ordinary course of
business of NFAKC, except to the extent of any reserves therefor reflected on
the Financial Statements or taken in the ordinary course of business consistent
with past practice that in the aggregate will not have a material adverse effect
upon the financial condition, results of operation, business,
<PAGE>
 
properties, assets, operations or prospects ("Material Adverse Effect") on
NFAKC.  All amounts previously collected by NFAKC in respect of accounts, notes
and other receivables of NFAKC are not subject to any valid defense, set off,
counterclaim or claim for returns or refunds, except for the right of the
Medicare and Medicaid programs to reopen cost reports, adjust open cost reports
and claim refunds against other amounts payable, in which cases NFAKC has the
unrestricted right to pursue all available appeals of any such reopening,
adjustment or claim, or as reflected in the Financial Statements.

disclosed in this Agreement or in the Schedules hereto, or (c) incurred in the
ordinary course of business consistent with past practice since December 31,
1995, that, individually or in the aggregate, do not have a Material Adverse
Effect on NFAKC.  Other than potential liabilities for which claims of

basis for any assertion against NFAKC of any liability or obligation of any
nature or in any amount not (d) fully reflected or adequately reserved against

properties have been paid, NFAKC has complied in all respects with its
obligations under the said leases to which it is a party and has not received
any notice of any breach of its obligations under any covenants, agreements,

Individuals, within the last five years, none of the employees of NFAKC (while
acting in the capacity of an employee of NFAKC ) has committed a violation of
the Medicare and Medicaid fraud and abuse provisions of the Social Security Act
or the Civil Monetary Penalties Law of the Social Security Act.

          (dd) Access to Books and Records.  All contracts of NFAKC with a value
               ---------------------------                                      
or cost of $10,000 or more over a twelve-month period entered into or renewed
since December 5, 1980, provide, or at the Effective Time of the Merger will
provide, to the extent required by law in conformity with Section 2 of the
Omnibus Reconciliation Act of 1980, P.L. 96499, for access to books and records
of subcontractors of Medicare providers by the
<PAGE>
 
Secretary of the Department of Health and Human Services.

          (ee) Inspection/Incident Reports.  (i) NFAKC has previously made
               ---------------------------                                
available for review by to RTC and the RTC Subsidiary true and complete copies
of all inspection/incident reports received since December 31, 1992 from the
state departments of health or other accreditation body of each state in which
NFAKC operates a health care facility.  NFAKC does not have any knowledge of any
change in any of the Facilities since the date of such reports that would make
any such reports inaccurate as of the date hereof.

               (ii) NFAKC has not received any notice of any claim, requirement
or demand of any Governmental Authority, accreditation body, third party payor
or any insurance body having or claiming any licensing, certifying, supervising,
evaluating or accrediting authority over any health care or dialysis facility
owned, leased or operated by NFAKC to rework or redesign such facility, its
professional staff or its professional services, procedures or practices in any
respect or to provide additional furniture, fixtures, equipment or inventory so
as to make such facility conform to or comply with any applicable legal
requirement.

          (ff) Medicare/Medicaid Participation/Accreditation.  All of the
               ---------------------------------------------             
Facilities have a current and valid provider contract with the Medicare and
Medicaid programs, if required, as an ESRD facility providing the ESRD services
indicated on the Patient List, are in  substantial compliance with the
conditions of participation of such programs and have received all approvals or
qualifications necessary for capital reimbursement of the applicable assets of
NFAKC.  NFAKC has not received notice from either the Medicare or Medicaid
program of any pending or threatened investigations or surveys, and NFAKC does
not have any reason to believe that any such investigations or surveys are
pending, threatened or imminent.  NFAKC has made available for review by RTC and
the RTC Subsidiary complete and correct copies of all surveys, reports or
deficiency notices concerning the Facilities by the Medicare program, the state
survey agency, the Medicaid Program or the respective state's kidney disease
program.  The Medicare certification of each Facility is in full force and
effect, and (i) no violation of the condition and standards of coverage,
participation or certification exists, and (ii) no event or circumstances exist
(other than failure to perform an obligation not yet due) which with the giving
of notice or passage of time would constitute a violation.

               (ii) Schedule 3.01(gg) sets forth a true and complete list of the
                    -----------------                                           
rates currently charged for all services provided by NFAKC, and to NFAKC's
knowledge all of which rates do not exceed the maximum allowable rate, if any,
imposed by any applicable law or regulation.  NFAKC does not have any rate
<PAGE>
 
appeal currently pending before any Governmental Authority or any administrator
of any third party payor program or referral source.

          (gg) Utilization Reviews.  The most recent utilization reviews
               -------------------                                      
relating to the Facilities by all applicable third party payors, accreditation
bodies and Governmental Authorities and reviews or scrutiny by any managed care
or utilization review companies have not had an adverse impact on the
utilization of programs at any such Facility.  No claims or assertions have been
made in any utilization review in possession of NFAKC or to which NFAKC has
access that any of the practices or procedures used at any such Facility are
improper or inappropriate.

          (hh) Operating Constraints.  There are no government contracts,
               ---------------------                                     
government permits or applicable legal requirements that require that a
percentage of slots or stations in any programs at any of the Facilities be
reserved for Medicaid or Medicare eligible patients or that any such facility
provide a certain amount of welfare, free or charity care or discontinued or
government-assisted patient care.

          (ii) Occupational Safety and Health.   NFAKC is in compliance with the
               ------------------------------                                   
applicable federal, state and local laws relating to occupational safety and
health, including, without limitation, the OSHA Bloodborne Pathogen Standard (29
C.F.R., 1910.130), and the general duty clause of the Occupational Safety and
Health Act (29 U.S.C.(S)654), other than violations which individually or
collectively would not have a Material Adverse Effect on NFAKC.

          (jj) RTC Common Stock Received; Lack of Registration Thereof;
               --------------------------------------------------------
Investment Intent.  None of the Individuals has any current plan or intention to
- -----------------                                                               
sell or otherwise dispose of more than fifty percent (50%) of the shares of RTC
Common Stock to be received by him upon consummation of the Merger.  The
Individuals understand that (i) the shares of RTC Common Stock to be issued to
the Individuals pursuant to the Merger will be issued under certain exemptions
from the registration provisions of the Securities Act of 1933 (the "Securities
Act"); (ii) the Individuals are acquiring the shares of RTC Common Stock without
being furnished any offering literature or prospectus; (iii) the issuance of the
shares of RTC Common Stock has not been examined by the Securities and Exchange
Commission or by any agency charged with the administration of the securities
laws of any state or other jurisdiction; and (iv) the Individuals have had the
opportunity to review certain materials, including financial information,
regarding RTC and the RTC Subsidiary and to ask questions of officers of the RTC
regarding RTC and the RTC Subsidiary.  Each of the Individuals represent and
warrant that he has such knowledge and experience in financial and business
matters that he is capable of evaluating the merits and risks of
<PAGE>
 
an investment in the shares of RTC Common Stock and of making an informed
investment decision with respect thereto.  Each of the Individuals understand
that RTC is relying on the truth and accuracy of the representations,
declarations and warranties made in this Section 3.01(kk) by the Individuals in
issuing the shares of RTC Common Stock without having first registered the
shares under the Securities Act or under the securities laws of any state or
other jurisdiction.  Each of the Individuals also confirms that (i) he
understands that there are substantial restrictions on the transferability of
the shares of RTC Common Stock he is to receive pursuant to the Merger and,
accordingly, it may not be possible for him to liquidate his investment in the
shares of RTC Common Stock in case of emergency and (ii) he is able to bear the
economic risk of his investment in the shares and to hold the shares for an
indefinite period of time.  The shares of RTC Common Stock are being acquired by
the Individuals in good faith solely for his own accounts, for investment
purposes only, and are not being acquired with a view to or for the resale,
distribution, subdivision or fractionalization thereof.  Neither of the
Individuals has any contract, undertaking, understanding, agreement or
arrangement, formal or informal, with any person to sell, transfer or pledge to
any person the shares of RTC Common Stock, or any part thereof, and neither of
the Individuals has any current plan to enter into any such contract,
undertaking, agreement or arrangement.  Each of the Individuals understands that
the legal consequences of the foregoing representations and warranties are that
he must bear the economic risk of his investment in the shares of the RTC Common
Stock for an indefinite period of time because the shares have not been
registered under the Securities Act.

          (kk) Sources of Revenue.  The sources of revenue of the business of
               ------------------                                            
each Facility consist of reimbursement for dialysis services, items and supplies
and related tests, studies, drugs, biologicals and blood provided by and through
the Facilities.  There are no other sources of revenue of the business of each
Facility.

          (ll) Accounting Matters. To the best knowledge of NFAKC and the
               ------------------                                        
Individuals based upon the representations and warranties set forth in that
certain pooling representation letter dated the date hereof addressed to Coopers
& Lybrand, L.L.P., neither the Individuals nor NFAKC have through the date of
this Agreement taken or agreed to take any action that (without giving effect to
this Agreement, the transactions contemplated hereby, or actions relating
thereto, or any taken or agreed to be taken by RTC or any of the RTC Subsidiary)
would prevent RTC from accounting for the business combination to be effected by
the Merger as a pooling of interests.

          (mm) Pooling of Interests Accounting.  The Individuals and NFAKC have
               -------------------------------                                 
consulted with Segers, Sowell & Stewart, P.A. as
<PAGE>
 
their independent accountants, regarding the availability of pooling of
interests accounting for the transactions contemplated hereunder.  Such
independent accountants have reviewed the amounts and timing of salary, bonus
and distribution payments to the Individuals during 1994, 1995 and 1996 (as set
forth in Schedule 3.01(mm) hereto) and such independent accountants have not
         -----------------                                                  
stated to the Individuals any doubt that pooling of interests accounting will be
available with respect to the transactions contemplated hereunder.  The
Individuals and NFAKC do not presently believe that the condition precedent
contained in Section 6.01(c) hereof will not be capable of satisfaction or that
the Individuals and NFAKC will be required to take any action pursuant to
Section 4.01(c)(ii) hereof.  The provisions of this Section 3.01(mm) are hereby
qualified to the extent that such independent accountants have not performed any
audits of NFAKC's financial statements and such independent accountants services
on behalf of their clients have been limited to compilations of financial
statements and tax return preparation.

          (nn) Material Misstatements or Omissions.  No representation or
               -----------------------------------                       
warranty by either the Individuals or NFAKC in this Agreement nor any documents,
exhibits, certificates or schedules furnished to RTC or the RTC Subsidiary
pursuant hereto, contains or will contain any untrue statement of a material
fact, or omits or will omit to state any material fact necessary to make the
statements or facts contained therein not misleading.  The copies of all
documents furnished to RTC or the RTC Subsidiary hereunder are true and complete
copies of the originals thereof in all material respects.

     SECTION 3.02.  Representations and Warranties of RTC and the RTC
                    -------------------------------------------------
Subsidiary.  RTC and the RTC Subsidiary hereby represent and warrant to NFAKC as
- ---------- 
follows:
 
          (a)  Corporate Existence and Power.  Each of RTC and the RTC
               ----------------------------- 
Subsidiary is a corporation duly incorporated, validly existing and in good
standing under the laws of the State of Delaware and has all corporate power and
authority necessary to enable it to own, lease or otherwise hold its properties
and assets and to carry on its business as now conducted and proposed to be
conducted.  RTC is duly qualified to do business as a foreign corporation and is
in good standing in each jurisdiction where the character of the property owned
or leased by it or the nature of its activities makes such qualification
necessary, except for those jurisdictions where the failure to be so qualified
would not, individually or in the aggregate, have a material adverse effect upon
the financial condition, results of operations, business, properties, assets,
operations or prospects of RTC or any of the RTC Subsidiary, individually or in
the aggregate (a "Material Adverse Effect on RTC"). RTC has previously made
available for inspection by the Individuals and to NFAKC true and complete
copies of the certificates of
<PAGE>
 
incorporation and by-laws of RTC and the RTC Subsidiary, as currently in effect.

          (b)  Corporate Authorization.  The execution, delivery and performance
               -----------------------                                          
by RTC and the RTC Subsidiary of this Agreement, and the consummation by RTC and
the RTC Subsidiary of the Merger and other transactions contemplated by this
Agreement, are within the corporate power and authority of RTC and the RTC
Subsidiary, respectively, and have been duly authorized by all necessary
corporate action.  This Agreement has been duly and validly authorized, executed
and delivered by RTC and the RTC Subsidiary and constitutes a valid and binding
obligation of RTC and the RTC Subsidiary enforceable against RTC and the RTC
Subsidiary in accordance with its terms.

          (c)  Governmental Authorization.  The execution, delivery and
               --------------------------                              
performance by RTC and the RTC Subsidiary of this Agreement, and the
consummation of the Merger and other transactions contemplated by this Agreement
by RTC and the RTC Subsidiary, do not and will not require any consent, approval
or action by or in respect of, or any declaration, filing or registration with,
any Governmental Authority, other than compliance with any applicable
requirements of the HSR Act, such ownership and disclosure forms and approvals
as may be required under federal and state health care and licensure laws and
regulations applicable to RTC, the RTC Subsidiary or any of their subsidiary,
approvals required under the health care and licensure laws and regulations of
the State of Florida, routine filings with the Secretary of State of the States
of Delaware and Florida, necessary to consummate the Merger, and compliance with
the applicable requirements of the Securities Act, the Securities Exchange Act
of 1934 (the "Exchange Act") and any applicable state securities and blue sky
laws in connection with the offer, sale and delivery of the shares of RTC Common
Stock to be issued in the Merger.

          (d)  Non-Contravention.  The execution, delivery and performance by
               -----------------
RTC and the RTC Subsidiary of this Agreement, and the consummation of the Merger
and other transactions contemplated by this Agreement by RTC and the RTC
Subsidiary, do not and will not, with or without the giving of notice, the lapse
of time or other:  (i) contravene or conflict with the certificates of
incorporation or by-laws of RTC or any of the RTC Subsidiary, (ii) assuming
compliance with the matters referred to in Section 3.02(c), contravene or
conflict with or constitute a violation of any provision of any law, rule,
regulation, judgment, injunction, order or decree binding upon or applicable to
RTC or any of the RTC Subsidiary, (iii) require any consent, approval or other
action by any person, contravene or conflict with or constitute a violation of
or a default under, or give rise to any right of termination, cancellation or
acceleration of any right or obligation of RTC or any of the RTC Subsidiary or
to
<PAGE>
 
a loss of any benefit to which RTC or any of the RTC Subsidiary is entitled,
under any material provision of any material agreement, contract, indenture, any
license, franchise, permit or other similar authorization held by RTC or any of
the RTC Subsidiary, or any lease or other instrument binding upon RTC or any of
the RTC Subsidiary, assuming compliance with the matters referred to in Section
3.02 (c), except for the consent of First Union National Bank of North Carolina
("FUNB") required under the Fourth Amended and Restated Loan Agreement dated as
June 5, 1996, among, inter alia, RTC and FUNB or (iv) result in the creation or
                     ----- ----                                                
imposition of any Lien on any asset of RTC or any of the RTC Subsidiary.

          (e)  Finders' Fee.  There is no investment banker, broker, finder or
               ------------                                                    
other intermediary that has been retained by or is authorized to act on behalf
of RTC or any of the RTC Subsidiary who might be entitled to any fee or
commission upon consummation of the transactions contemplated by this Agreement.

          (f)  Litigation.  There is no action, suit, investigation or
               ----------
proceeding pending against, or to the knowledge of RTC and the RTC Subsidiary
threatened against, RTC or the RTC Subsidiary before any court or arbitrator or
any Governmental Authority that, if decided adversely to RTC or the RTC
Subsidiary would result in a Material Adverse Effect on RTC or the RTC
Subsidiary.

          (g)  Capitalization.  (i)  As of December 31, 1995, the authorized
               --------------                                               
capital stock of RTC consisted of (1) 5,000,000 shares of Preferred Stock, par
value $.01 per share, of which no shares were issued and outstanding or held in
the treasury of RTC, and (ii) 20,000,000 shares of RTC Common, of which
10,845,056 shares were issued and outstanding and 18,601 shares were held in the
treasury of RTC.  As of December 31, 1995, there were reserved for issuance
under RTC's stock option plans 842,111 shares of RTC Common Stock.  As of
December 31, 1995, there were outstanding options to purchase 631,199 shares of
RTC Common Stock under RTC's stock option plans.  Except as set forth above, as
of December 31, 1995, there were no outstanding (i) shares of capital stock or
other voting securities of RTC, (ii) securities of RTC convertible into or
exchangeable for shares of capital stock or voting securities of RTC or (iii)
(except for the right of the third party from whom RTC acquired certain assets
to require RTC to issue shares of its Common Stock in payment of a note)
options, warrants, exchange rights, subscription rights or other agreements,
commitments or rights to purchase or otherwise acquire from RTC, or agreements,
commitments or obligations of RTC to issue or sell, any capital stock, voting
securities  or securities convertible into or exchangeable for capital stock or
voting securities of RTC (items in clauses (i), (ii) and (iii) being referred to
collectively as the "RTC Securities").
<PAGE>
 
               (ii) The authorized capital stock of the RTC Subsidiary consists
of 1,000 shares of Common Stock, par value $1.00 per share, 100 of which are
issued and outstanding and owned of record by RTC. All issued and outstanding
shares of Common Stock of the RTC Subsidiary are validly issued, fully paid and
nonassessable, and have not been issued in violation of any preemptive, first
refusal or other subscription rights of any stockholder of RTC, the RTC
Subsidiary or any other person.

          (h)  Reports and Financial Statements.  RTC has previously furnished
               --------------------------------
to NFAKC true and correct copies of (i) its Annual Report on Form 10-K for the
fiscal year ended December 31, 1995, (ii) its Quarterly Report on Form 10-Q for
the period ended March 31, 1996 and (iii) all other reports or registration
statements filed by it with the Commission under the Exchange Act since December
31, 1995 all in the form (including exhibits) so filed (collectively, the
"Reports").  As of their respective dates, the Reports did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.  Each of the audited
consolidated financial statements and unaudited interim financial statements
included in the Reports has been prepared in accordance with generally accepted
accounting principles applied on a consistent basis (except as may be indicated
therein or in the notes thereto) and fairly presents the financial position of
the entity or entities to which it relates as at its date or the results of
operations, stockholders' equity or cash flows, subject to normal year-end
adjustments and any other adjustments described therein, which adjustments will
not be material in amount or effect.

          (i)  Compliance with Laws; No Defaults.  (i)  Neither RTC nor any RTC
               ---------------------------------                               
Subsidiary is in violation of, and since December 31, 1995 has not violated, any
applicable provisions of any laws, statutes, ordinances or regulations, except
for violations that could not reasonably be expected to have, individually or in
the aggregate, a Material Adverse Effect on RTC.

               (ii) Neither RTC nor any RTC Subsidiary is in default under, and
no condition exists that with notice or lapse of time or both would constitute a
default under, (A) any mortgage, loan agreement, indenture or evidence of
indebtedness for borrowed money to which RTC or any RTC Subsidiary is a party or
by which any of their assets is bound, which defaults or potential defaults,
individually or in the aggregate, have had, or could reasonably be expected to
have, a Material Adverse Effect on RTC or (B) any judgment, order or injunction
of any court, arbitrator or Governmental Authority.

          (j)  Pooling of Interests Accounting.  RTC has consulted with Coopers
               -------------------------------
& Lybrand, L.L.P. as its independent
<PAGE>
 
auditors, regarding the availability of pooling of interests accounting for the
transactions contemplated hereunder.  Such auditors have reviewed the amounts
and timing of salary, bonus and distribution payments to the Individuals during
1994, 1995 and 1996 (as set forth in Schedule 3.01(mm) hereto) and such auditors
                                     -----------------                          
have not stated to RTC any material doubt that pooling of interests accounting
will be available with respect to the transactions contemplated hereunder.  RTC
does not presently believe that the condition precedent contained in Section
6.01(c) hereof will not be capable of satisfaction or that the Individuals will
be required to take any action pursuant to Section 4.01(d)(ii) hereof.

          (k)  Issuance of the Total Shares.  The issuance and delivery by RTC
               ----------------------------
of the Total Shares in connection with the Merger and this Agreement have been
duly and validly authorized by all necessary corporate action on the part of
RTC. The Total Shares of RTC Common Stock to be issued in connection with the
Merger and this Agreement, when issued in accordance with the terms of this
Agreement, will be validly issues, fully paid and nonassessable.

          (l)  Absence of Certain Changes.  Except as disclosed in the Reports
               --------------------------                                     
filed with the SEC prior to the date hereof, since December 31, 1995, RTC has
conducted its business only in the ordinary course of such business and there
has not been (i) any Material Adverse Effect on RTC; or (ii) any change in its
accounting principles, practices or methods.

          (m)  Material Misstatements or Omissions.  No representation or
               -----------------------------------                       
warranties by RTC in this Agreement nor any Reports, documents, exhibits,
certificates or schedules furnished to NFAKC or the Individuals pursuant hereto,
contains or will contain any untrue statement of a material fact, or omits or
will omit to state any material fact necessary to make the statements or facts
contained therein not misleading.  The copies of all documents furnished to
NFAKC hereunder are true and complete copies of the originals thereof in all
material respects.

     (n)  Reimbursement Claims.  RTC has not made any claim for reimbursement
          --------------------                                               
under Medicare, Medicaid or any other payor programs without a substantial basis
for such claim other than billing errors occurring in the ordinary course of
business which billing errors have not had and will not have a Material Adverse
Effect on RTC.  RTC has not received any notice that any Medicare, Medicaid or
any other payor programs have any claims against it that could result in a net
offset against past or future reimbursement.  RTC has no liability for any
overpayment, refund, discount or adjustment ("Overpayment") in connection with
Medicare, Medicaid or any other reimbursement program or third party payer,
except Overpayments customary in the business.  No reimbursement program or
payor has made or threatened any claim
<PAGE>
 
for any Overpayment.  No Facility has ever claimed or received from the Medicare
program reimbursement for bad debts.  To the best knowledge of RTC, within the
last five years, none of the employees of RTC (while acting in the capacity of
an employee of RTC)) has committed a violation of the Medicare and Medicaid
fraud and abuse provisions of the Social Security Act or the Civil Monetary
Penalties Law of the Social Security Act.

                                   ARTICLE IV

                   Covenants Relating to Conduct of Business
                   -----------------------------------------

     SECTION 4.01.  Conduct of Business.
                    ------------------- 

     (a)  Conduct of Business by NFAKC.  During the period from the date of this
          ----------------------------                                          
Agreement to the Effective Time of  the Merger, NFAKC shall and the Individuals
shall cause NFAKC to, carry on its business in the usual, regular and ordinary
course in substantially the same manner as heretofore conducted and, to the
extent consistent therewith, use all reasonable efforts to preserve intact its
current business organizations, keep available the services of its current
officers and employees, preserve its relationships with customers, suppliers,
licensors, licensees, distributors and others having business dealings with it
to the end that its goodwill and ongoing businesses shall be unimpaired at the
Effective Time of the Merger.

Without limiting the generality of the foregoing, during the period from the
date of this Agreement to the earlier of the Effective Time of the Merger or the
date on which this Agreement is terminated, NFAKC shall not:

                    (i)  (x)  declare, set aside or pay any dividends on, or
          make any other distributions in respect of, any of its capital stock,
          (y) split, combine or reclassify any of its capital stock or issue or
          authorize the issuance of any other securities in respect of, in lieu
          of or in substitution for shares of its capital stock or (z) purchase,
          redeem or otherwise acquire any shares of capital stock of NFAKC or
          any other securities thereof or any rights, warrants or options to
          acquire any such shares or other securities;

                    (ii) issue, deliver, sell, pledge or otherwise encumber any

<PAGE>
 
          effect to any action taken or agreed to be taken by RTC or any of its

          from treating the Merger as a "reorganization" under Section 368(a) of
          the Code; or

                    (xii)     authorize any of, or commit or agree to take any

directly or indirectly, through any officer, director, employee, representative

the foregoing.

Subsidiary each hereby agrees (i) not to take any action that would adversely
affect the ability of RTC to treat the Merger as a pooling of interests, and
(ii) to take such action as may be reasonably required to negate the impact of
any past actions which would adversely affect the ability of RTC to treat the
Merger as a pooling of interests in accordance with generally accepted
accounting principles consistently applied and all published rules, regulations
and policies of the Securities Exchange Commission as in effect on the date
hereof.

          (d)  Other Actions.  NFAKC on the one hand and RTC and the RTC

untrue, (ii) any of such representations and warranties that are not so
qualified becoming untrue in any material respect or (iii) any of the conditions
to the Merger set forth in Article VI not being satisfied.

any part thereof, the holder thereof shall deliver written notice to RTC
describing in reasonable detail the transfer or proposed transfer, together with
an opinion of counsel that it is knowledgeable in securities law matters and
reasonably acceptable to RTC, to the effect that such transfer may be effected
without registration under the Securities Act and under applicable state
securities laws. In addition, if the holder of the securities to be transferred
delivers to RTC an opinion of counsel that no subsequent transfer of such RTC
Common Stock will require registration under the Securities Act or under
applicable state securities laws, RTC shall promptly upon such contemplated
transfer deliver new certificates for such RTC
<PAGE>
 
Common Stock that do not bear the restrictive legend set forth in Section
5.01(b)(i) hereof.  If RTC is not required to deliver new certificates for such
RTC Common Stock not bearing such legend, the holder thereof shall not transfer
such RTC Common Stock until the prospective transferee has confirmed to RTC in
writing his or its agreement to be bound by the conditions contained in this
Section 5.01(a).

          (b)  Restrictive Legends.  The RTC Common Stock and any shares of
               -------------------

                    THE SECURITIES ACT OF 1933 OR THE SECURITIES LAWS OF ANY
                    STATE.  THESE SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN
                    THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM
                    UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS.

               (ii) THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
                    TO RESTRICTIONS ON TRANSFERABILITY SET FORTH IN SECTIONS
                    5.01 AND 5.06 OF THE AGREEMENT AND PLAN OF MERGER, DATED AS

file all reports required to be filed by it under the Exchange Act and the rules
and regulations thereunder and shall take such further action as any holder of
RTC Common Stock may reasonably request, all to the extent required to enable
any such holder to sell the RTC Common Stock pursuant to Rule 144 under the
Securities Act (as such rule may be amended from time to time) or any similar
rule or regulation then in force.  Upon written request, RTC shall deliver to
any holder of any RTC Common Stock a written statement as to whether RTC is in
compliance with such requirements.

          (d)  S-3 Registration Rights.

               (i)  Registration Rights.  RTC will register the shares of RTC
                    ------------------- 
Common Stock issued to the Individuals in the Merger within the seventy (75)
days following the Effective Time of the Merger on Form S-3 under the Securities
Act, or any successor to such form in a manner that will, upon being declared
effective, constitute a "shelf" registration for purposes of Rule 415 under the
Securities Act, pursuant to which the Shareholder may sell the shares of RTC
Common Stock received by him in the Merger, from time to time and in such
amounts as Shareholder may hereafter determine, all in a manner consistent with
the provisions of 5.07(a) hereof, Exhibit D hereto and all applicable provisions
of the Securities Act and the Exchange Act. RTC will use its best efforts to
have the Form S-3 declared effective.

               (ii) Registration Procedure.  With respect to registration under
                    ----------------------                                     
Section 5.01(d)(i), RTC shall prepare and file such amendments, post-effective
amendments and periodic reports under the Exchange Act as may be necessary to
keep such registration statement continuously effective until the second
anniversary of the Closing Date.  Notwithstanding the foregoing, RTC shall not
be required to update, pursuant to this Section 5.01(d), any document during a
period when RTC shall, in good faith and using reasonable business judgment,
believe that the premature disclosure of any event or information would have a
Material Adverse Effect on RTC or its prospects.  The Individuals hereby agree,
that upon receipt of notice from RTC of the happening of any occurrence
described in the preceding sentence, each of the Individuals shall forthwith
discontinue disposition of the shares of RTC Common Stock received by him in the
Merger pursuant to such registration statement until the Individuals's receipt
of the copies of the supplemented or amended prospectus, and, if so directed by
RTC, each of the Individuals shall deliver to RTC all copies in his possession,
other than permanent file copies then in such Individuals's possession, of the
prospectus covering such RTC Common Stock current at the time of receipt of such
notice.

                      --------

without limitation, all registration and filing fees, printing expenses, and
costs of special audits incident to or required by such registration) or the
transactions contemplated herein.

          (e)  Further Actions by the Individuals.  Each of the Individuals
               ----------------------------------                          
agrees to furnish to RTC and the RTC Subsidiary such

received by him in the Merger and the intended method of disposition thereof as
RTC shall reasonably request and as shall be required in connection with the
actions to be taken by RTC under the provisions of Section 5.01(d) above.  Each
of the Individuals further agrees to comply with all provisions of the
Securities Act and the Exchange Act and all applicable state securities law.

     SECTION 5.02.  Best Efforts; Notification.  (a)  Upon the terms and subject
                    --------------------------                                  
to the conditions set forth in this Agreement, each of the parties agrees to use
its best efforts to take, or cause to be taken, all actions, and to do, or cause
to be done, and to assist and cooperate with the other parties in doing, all
things necessary, proper or advisable to consummate and make effective, in the
most expeditious manner practicable, the  Merger and the other transactions
contemplated by this Agreement, including (i) the obtaining of all necessary
actions or nonactions, waivers, consents and approvals from Governmental

steps as may be necessary to obtain an approval or waiver from, or to avoid an
action or proceeding by any Governmental Authority, (ii) the obtaining of all
necessary consents, approvals or waivers from third parties and (iii) the
execution and delivery of any additional instruments necessary to consummate the

RTC Subsidiary, and RTC and the RTC Subsidiary shall give prompt notice to the
Individuals and NFAKC, of (i) any representation or warranty made by it
contained in this Agreement that is qualified as to materiality becoming untrue
or inaccurate in any respect or any such representation or warranty that is not
so qualified becoming untrue or inaccurate in any material respect or (ii) the
failure by it to comply with or satisfy in any material respect any covenant,
condition or agreement to be complied with or satisfied by it under this
Agreement; provided, however, that no such notification shall affect the
           -----------------                                            
representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under this Agreement.

     SECTION 5.03 (a).  Indemnification by NFAKC and Individuals.  (i) NFAKC and
                        ----------------------------------------                
the Individuals, jointly and severally, agree to indemnify, defend and hold
harmless RTC and the RTC Subsidiary, at any time after the Closing from and
against all liabilities, losses, claims, costs or damages whatsoever, including
expenses and reasonable fees of legal counsel (collectively, "RTC Indemnified
Losses"), arising out of or from or based upon:
<PAGE>
 
     (A)  the inaccuracy of any representation or warranty contained herein made
by NFAKC or the Individuals;

     (B)  the non-performance or breach by NFAKC or the Individuals of any
covenant, agreement or obligation to be performed by NFAKC or the Individuals
hereunder; or

     (C)  any contract or arrangement entered into prior to the Closing Date
between NFAKC and the Individuals that did not or may not have satisfied the
provisions of federal and state laws and regulations relating to restrictions on
physician referrals or claims for payment under the Medicare, Medicaid or other
programs for the furnishing of health services, including, but not limited to
the provisions of the Omnibus Budget Reconciliation Act of 1993 which failure
could have a Material Adverse Effect on NFAKC.

     (ii) The indemnification for any RTC Indemnified Losses pursuant to this
Section 5.03(a) shall be calculated net of any net tax benefit (giving effect to
the payment of any additional taxes that may be incurred by RTC or the RTC
Subsidiary from treatment of such indemnification payments as taxable income or
gain to RTC or the RTC Subsidiary) to RTC or the RTC Subsidiary (utilized by RTC
or the RTC Subsidiary against income of RTC or the RTC Subsidiary in the year
that RTC or the RTC Subsidiary deducts such liability, loss, claim, cost or
expense in its income tax returns, regardless of whether RTC or the RTC
Subsidiary receives any tax benefits in any other year by reason of any net
operating loss or other available income tax carryforwards or carrybacks),
resulting from such RTC Indemnified Losses, provided that the amount of any tax
liabilities arising from the payment of such indemnification shall not increase
the amount of the underlying claim.

     (iii)     Limitation on Liability.  NFAKC and the Individuals shall not be
               -----------------------                                         
liable under this Section 5.03(a) for RTC Indemnified Losses in the event that
RTC Indemnified Losses in the aggregate are less than $60,000.  If the aggregate
amount of RTC Indemnified Losses exceeds $60,000 then RTC and the RTC Subsidiary
may claim indemnification for the aggregate amount of RTC Indemnified Losses
less $60,000.  In no event shall the obligations of NFAKC and the Individuals
for RTC Indemnified Losses exceed $2,400,000.  In addition, the individual joint
and several liability of each Individual shall not exceed Eight Hundred Thousand
Dollars ($800,000).

     (iv) Indemnification Payment in RTC Shares.  In the event that the
          -------------------------------------                        
Individuals become obligated under the provisions of this Section 5.03(a) to
indemnify RTC and RTC Subsidiary for RTC Indemnified Losses, the Individuals
shall have the right to pay the amount of the applicable RTC Indemnified Loss,
in whole and not in part, in RTC Common Stock by transferring to RTC and/or
<PAGE>
 
RTC Subsidiary a number of the shares of RTC Common Stock received by them
hereunder having an aggregate value equal to the amount of the RTC Indemnified
Loss; provided that such shares shall be valued based upon the closing price of
RTC Common Stock as of the Effective Time of the Merger.  In the event that the
aggregate value of the RTC Comon Stock owned by the Individuals is less than the
amount of the applicable RTC Indemnified Loss, the Individuals must pay the RTC
Indemnified Loss in cash and not in RTC Common Stock.
 
     (b)  Indemnification by RTC.  (i) RTC agrees to indemnify, defend and hold
          ----------------------                                               
harmless NFAKC and the Individuals, at any time after the Closing from and
against all liabilities, losses, claims, costs or damages whatsoever, including
expenses and reasonable fees of legal counsel (collectively, "NFAKC Indemnified
Losses") arising out of or from or based upon:

     (A)  the inaccuracy of any representation or warranty contained herein made
by RTC or the RTC Subsidiary;

     (B)  the non-performance or breach by RTC or the RTC Subsidiary of any
covenant, agreement or obligation to be performed by RTC or the RTC Subsidiary
hereunder; or

     (C)  any and all liabilities, losses, claims, costs or damages whatsoever
relating to the Registration Statement on Form S-3 to be filed by RTC pursuant
to Section 5.01 of this Agreement (the "Registration Statement") or the failure
to so file such Form S-3 other than liabilities, losses, claims, costs or
damages resulting from (A) information provided in writing by or on behalf of
either of the Individuals or (B) the failure of either of the Individuals to
disclose to RTC any fact relating to either of the Individuals required to be
disclosed in the Registration Statement.

     (ii) The indemnification for any NFAKC Indemnified Losses pursuant to this
Section 5.03(b) shall be calculated net of any net tax benefit (giving effect to
the payment of any additional taxes that may be incurred by NFAKC or the
Individuals from treatment of such indemnification payments as taxable income or
gain to NFAKC or the Individuals) to NFAKC or the Individuals (utilized by NFAKC
or the Individuals against income of NFAKC or the Individuals in the year that
NFAKC or such Individual deducts such liability, loss, claim, cost or expense in
its or his income tax returns, regardless of whether NFAKC or such Individuals
receive any tax benefits in any other year by reason of any net operating loss
or other available income tax carryforwards or carrybacks), resulting from such
NFAKC Indemnified Losses, provided that the amount of any tax liability arising
from the payment of such indemnification shall not increase the amount of the
underlying claim.
<PAGE>
 
     (iii)     Limitation on Liability.  RTC shall not be liable under this
               -----------------------                                     
Section 5.03(b) for NFAKC Indemnified Losses in the event that NFAKC Indemnified
Losses in the aggregate are less than $60,000.  If the aggregate amount of NFAKC
Indemnified Losses exceeds $60,000 then NFAKC and Individuals may claim
indemnification for the aggregate amount of NFAKC Indemnified Losses less
$60,000.  In no event shall the obligations of RTC for NFAKC Indemnified Losses
exceed $2,400,000.

     (c)  Conditions of Indemnification.
          ----------------------------- 
 
     (i)  Whenever any claim is made by any person not a party to this Agreement
with respect to any matter to which the indemnifications contained in this
Section 5.03 relate, the indemnified party (the "Indemnitee") shall notify the
indemnifying party (the "Indemnitor") in writing within twenty (20) days after
the Indemnitee has written notice of the facts constituting the basis for such
claim (the "Notice of Claim").  Whenever any claim is made by one of the parties
to this Agreement with respect to any matter to which the indemnification
contained in this Section 5.03 relates, as soon as practicable after the
Indemnitee becomes aware of such claim, the Indemnitee shall send a Notice of
Claim to the Indemnitor.  The Notice of Claim shall specify all facts known to
the Indemnitee giving rise to such indemnification claim and the amount of an
estimate of the amount of the liability arising therefrom.  The Notice of Claim
shall be given in accordance with Section 8.03 hereto.

     (ii) Each claim will be deemed approved by the Indemnitor, unless the
Indemnitor gives the Indemnitee written notice of disapproval within thirty (30)
days of receipt of such second Notice of Claim.  The parties shall undertake, in
good faith, to resolve any dispute with respect to any such claim which is so
disapproved; if the parties are unable to agree on such resolution within thirty
(30) days after the Indemnitee receives notice of disapproval from the
Indemnitor, the respective rights of the parties shall be determined by
arbitration in Panama City, Florida, in accordance with the rules of the
American Arbitration Association.  If the two parties cannot  jointly select a
single arbitrator to determine the matter, one arbitrator shall be chosen by
each party (or, if a party fails to make a choice, by the American Arbitration
Association on behalf of such party) and the two arbitrators so chosen will
select a third.  The decision of the single arbitrator jointly selected by the
parties, or, if three arbitrators are selected, the decision of any two of them,
will be final and binding upon the parties and the judgement of a court of
competent jurisdiction may be entered thereon.  Fees of the arbitrators and
costs of arbitration shall be borne by the parties in such manner as shall be
determined by the arbitrator or arbitrators.

     (iii)     If the facts giving rise to any such
<PAGE>
 
indemnification shall involve any actual, threatened or possible claim or demand
by any person against the Indemnitee, the Indemnitor shall be entitled to
contest or defend such claim at its expense and through counsel of its own
choosing if it gives written notice of its intention to assume the contest and
defense of such claim to the Indemnitee within thirty (30) days after receipt
of the Notice of Claim.  If the Indemnitor shall exercise such option, it shall
have control over such contest and defense and over the payment, settlement or
compromise of such claim, and the Indemnitee agrees to cooperate fully with the
Indemnitor and its attorneys with respect to such contest and defense.  If the
Indemnitor shall not exercise such option, the Indemnitee may, but shall not be
obligated to, assume the contest and defense of such claim.  Any payment or
settlement resulting from such contest, together with the total expenses
thereof, including but not limited to attorneys' fees, shall be binding upon the
Indemnitor and the Indemnitee.

     (d)  Actual Knowledge.  An Indemnitor shall not be liable under this

               or (b), as applicable, and (B) cannot be or has not been cured

     SECTION 7.02.  Effect of Termination.
                    --------------------- 

          (a)  Agreement Void and of No Effect.  In the event of termination of
               -------------------------------                                 
     this Agreement as provided in Section 7.01, this Agreement shall forthwith
     become void and have no effect, without any liability or obligation on the
     part of RTC, the RTC Subsidiary, the Individuals or NFAKC, other than the
     provisions of Section 7.02 and all of Article VIII and except to the extent
     that such termination results from the willful and material breach by a
     party of any of its representations, warranties, covenants or agreements
     set forth in this Agreement.

          (b)  Expenses. Notwithstanding anything herein to the contrary, in the
               --------                                                       
                                              
     event this Agreement is terminated (i) due to a failure of the shareholders
     of any of the corporate parties hereto to approve this Agreement and the
     transactions contemplated hereby or (ii) by RTC or the RTC Subsidiary due
     to a Breach by the Individuals or NFAKC, or by the Individuals or NFAKC due
     to a Breach by RTC or the RTC Subsidiary, then the other party shall be
     entitled to reimbursement from the other, jointly and severally, within ten
     (10) days after written demand therefor for all fees and expenses incurred
     by such other party in connection with this Agreement and the transactions
     contemplated hereby.

          (c)  Specific Performance, Injunctive Relief and Other Remedies.  In
               ----------------------------------------------------------     
     the event (a) this Agreement is terminated (i) due to a failure of the
     shareholders of NFAKC to approve this Agreement and the transactions
     contemplated hereby or (ii) by RTC or the RTC Subsidiary due to a breach by
     the Individuals, and (b) NFAKC  is involved in a "Change of Control", as
     defined herein, within one (1) year after such termination and any
     preliminary contracts or discussions with any of the Individuals and or
     NFAKC or any representative thereof relative thereto occurred prior to the
     termination of this Agreement, then the Individuals and NFAKC acknowledge
     and agree that any intentional and material breach by them of the
     provisions of this Agreement will cause RTC and the RTC Subsidiary
     irreparable injury and damage, for which RTC and the RTC Subsidiary cannot
     be adequately compensated in damages.  Therefore, the Individuals and NFAKC
     expressly agree that RTC and the RTC Subsidiary shall, in addition to all
     other remedies legally available to them, be entitled to specific
     performance,
<PAGE>
 
     preliminary and permanent injunctive relief and/or other equitable relief
     to prevent any anticipatory or continuing breach of this Agreement, or any
     part thereof, and to secure its enforcement and shall be entitled to the
     recovery of reasonable attorney's fees and costs in connection therewith.
     Nothing herein shall be construed as a waiver by RTC or the RTC Subsidiary
     of any right they may now have or hereafter acquire to monetary damages,
     including without limitation consequential damages and special damages, by
     reason of any injury to their property, business or business prospects or
     otherwise arising out of any wrongful act or omission of the Individuals
     and/or NFAKC hereunder.  The Individuals and NFAKC acknowledge that the
     provisions of this Section 7.02(c) are made as part of a contract for the
     sale of a business interest; the parties are of equal bargaining power; RTC
     and the RTC Subsidiary would not acquire the capital stock of NFAKC from
     the Individuals as the sole shareholders of NFAKC in exchange for shares of
     capital stock of RTC as provided in this Agreement except in consideration
     of the provisions of this Section 7.02(c); the restrictions contained
     herein are reasonable and necessary to protect the legitimate interests of
     RTC, the RTC Subsidiary and their Affiliates; and any violation of these
     restrictions would result in irreparable injury to RTC and its Affiliates
     not compensable by payment of monetary damages.  If any provision of this
     Section 7.02(c) shall be invalid or unenforceable, in whole or in part,
     then such provision shall be deemed to be modified or restricted to the
     extent and in the manner necessary to render the same valid and
     enforceable, or shall be deemed excised from this Section 7.02(c), as the
     case may require, and this Section 7.02(c) shall be construed and enforced
     to the maximum extent permitted by law as if such provision had been
     originally incorporated herein as so modified or restricted or as if such
     provision had not been originally incorporated herein, as the case may be.

     SECTION 7.03. Amendment.  This Agreement may be amended by  the parties at
                   ---------                                                   
any time; provided, however, there shall be made no amendment that by law
          --------  -------                                              
requires further approval by such stockholders of any of the parties hereto
without the further approval of the stockholders.  This Agreement may not be
amended except by an instrument in writing signed on behalf of each of the
parties.

     SECTION 7.04. Extension; Waiver.  At any time prior to the Effective Time
                   -----------------                                          
of the Merger, the parties may (a) extend the time for the performance of any of
the obligations or other acts of the other parties, (b) waive any inaccuracies
in the representations and warranties of the other parties contained in this
Agreement or in any document delivered pursuant to this Agreement, or (c)
subject to the proviso of Section 7.03, waive
<PAGE>
 
compliance by the other parties with any of the agreements or conditions
contained in this Agreement.  Any agreement on the part of a party to any such
extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party.  The failure of any party to this Agreement to
assert any of its rights under this Agreement or otherwise shall not constitute
a waiver of such rights.

     SECTION 7.05. Procedure for Termination, Amendment,  Extension or Waiver.
                   ----------------------------------------------------------  
A termination of this Agreement pursuant to Section 7.01, an amendment of this
Agreement pursuant to Section 7.03 or an extension or waiver pursuant to Section
7.04 shall, in order to be effective, require in the case of RTC, the RTC
Subsidiary or NFAKC, action by its Board of Directors or the duly authorized
designee of its Board of Directors.
